Technical situation

Summary

Introduction

• Health care IT is health care information technology.  The AHRQ argues HCIT consists of a complex set of technologies, policies, standards and user sets.  Technically they represent it as a set of layers: Application: CPOE, CDS, e-prescribing, eMAR, Results reporting, Electronic documentation, Interface engines, etc.; Communication: Messaging standards (HL7, ADT, NCPDP, X12, DICOM, ASTM, etc,) Coding standards (LOINC, ICD10, CPT, NDC, RxNorm, SNOMED CT, etc.), Process: HIE, MPI, HIPAA security & privacy, etc.; Device: Tablet and PC, ASP, PDAs, Bar Coding, etc.; 
  offers to: Enhance the quality/process, extend the intelligence, increase the transparency, reduce the cost, improve RCM is either:
  
  • Restrictive cardiomyopathy, a rare disease where scar tissue makes the heart muscle rigid and reduces the efficiency.  Or
    
  • Revenue Cycle Management aligns treatment with reimbursement.  Customer service will be involved.  IT will architect the core billing, decision support and ad-hoc services, constructed by RCM vendors, into systems to support RCM.  The Hospital's central business office will aim to maximize cash recoveries.  As per Deming, mistakes in the RCM pipeline result in rework and lost cash flow and revenue of between 4 - 12%.  The staff must be trained and fully engaged in the design and operation of the pipeline.  The front end processes are best placed to capture all the information needed to make the cycle successful.  The activities include:
  • Scheduling and Appointments - where visits and procedures are booked and demographic and insurance information is collected.  If this information is incorrect it is likely the claims will not forward to third party payers.  When resources and their states are accurately known an optimal set of plans can be constructed to efficiently and effectively flow patients through the system.  But that is difficult to guarantee because of a number of interrelated problems:
  • Scale - as the number of resources increases the ability of a central scheduling system to represent all of them accurately and reliably becomes impossible. 
    
  • Ubiquity - a CAS strategy for ensuring availability is to have an over-abundance of equivalent resource that can be used for schedule allocation.  But often these resource levels are set by local decision makers who all respond at about the same time to imposed funding changes.  The effect is to suddenly and unpredictably undermine the guarantee of over-abundance.  Sometimes the assumption of equivalence also fails as in the desire of a patient to see only a specific surgeon. 
    
  • Changes can ripple through the plans requiring coordination meetings and notifications or guaranteed receipt of status updates. 
    
  • Verification checks for:
    
  • Referral - Is there PCP authorization?  Is the PCP referred service covered by the patient's plan,
    
  • Authorization - obtain Insurance authorization if required, and
    
  • Pre-certification - is there 'need' for inpatient care or other care before admission by the MCO.  Otherwise could introduce problems including not obtaining/verifying the insurance name, number and eligibility, not securing pre-certification and pre-authorization with time limits, not copying the insurance card, not checking for secondary coverage, not detecting expired referral or authorization,
    
  • Pre-registration - provide advice about their financial obligations and what documents to bring to the procedure.  If there is a copay or an outstanding payment to be paid these should be processed,
    
  • Registration - some patients are scheduled outside of the main admitting process (by OP clinic or E.D.) and this must be detected and the scheduling verification and pre-registration process be performed,
    
  • Time of service payments - co pays and self pays,
    
  • Coding - identify diagnosis (ICD 9 -> ICD-10 codes) and treatment (CPT) activities and charges for the episode.  More than 80% of hospital cases are coded in error. 
    
  • Demographics and billing data entry - enter charges and adjust capitated charges,
    
  • Patient statements - submit primary and secondary claims (following HIPAA formats) with or without involvement of a clearinghouse, produce patient statements including time of service, outstanding balance, charged amount with codes, insurance details, forms used (UB 92/04 and HCFA 1500).  A paper based claims filing has a rejection rate of 30%.  Duplicate claim payment rates of 1 - 2% of medical expenses are common.  Duplicate claims detection is often not part of the process.  Payer's goals are in conflict with Provider goals.  
    
  • Collections and payment posting - Post all payments and adjustments and deposit money into the bank,
    
  • Denials and appeals - resubmission and appeal of claims, denial analysis and bad debts and write offs.  To reduce denial rates and appeals the reimbursement contracts payer processes and actual denials must be analyzed and understood. 
    
  • Account follow up - Patient inquiries, resubmission of claims and issue refunds. 
    
  • Financial counseling;
  and extend the reach of health care;
• Central banks look at bitcoin is a set of open-source software, used to provide infrastructure that supports a distributed cryptocurrency and payment system, based on the blockchain.   All transaction inputs are unspent outputs from previous transactions.  All transaction inputs are signed.  Change is provided in an additional output to the transaction. 
  's blockchain is a bitcoin distributed database technology that allows several bitcoin operators to keep a shared, cryptographically verified, ledger and consensus mechanism to allow agreement on what transactions have happened and in what order.  It implements a Merkle tree.  Six times an hour on average, a new group of validated transactions, a block, is created, added to the local block chain and published to all nodes.  Paraphrasing breadwallet's Aaron Voisine, publishing is robust because: Each operator has connected via references from its initial peers to a random subset of all the other operators; and the new block is offered to the connected peers who can both ask for it if they have not seen it previously from some other source and pass it on to their other peers in a cascade (a gossip network).  To build new blocks an operator must have all the prior blocks in the chain.  All unspent bitcoins are represented [only] in the blockchain.  Miners keep the blockchain consistent by verifying that a new block has a proof-of-work.  This requires that miners find a nonce that multiplied by the block hash is smaller than the network's difficulty target.   to develop a distributed ledger (Oct 2016)

• Prosecutor Haun and TSRI's Topol review the problem and a blockchain is a bitcoin distributed database technology that allows several bitcoin operators to keep a shared, cryptographically verified, ledger and consensus mechanism to allow agreement on what transactions have happened and in what order.  It implements a Merkle tree.  Six times an hour on average, a new group of validated transactions, a block, is created, added to the local block chain and published to all nodes.  Paraphrasing breadwallet's Aaron Voisine, publishing is robust because: Each operator has connected via references from its initial peers to a random subset of all the other operators; and the new block is offered to the connected peers who can both ask for it if they have not seen it previously from some other source and pass it on to their other peers in a cascade (a gossip network).  To build new blocks an operator must have all the prior blocks in the chain.  All unspent bitcoins are represented [only] in the blockchain.  Miners keep the blockchain consistent by verifying that a new block has a proof-of-work.  This requires that miners find a nonce that multiplied by the block hash is smaller than the network's difficulty target.   solution for Health Data breaches (Jan 2017)
• Congress concludes Chinese distributors ship fentanyl is a synthetic opioid pain medication that acts on micro-opioid receptors in the brain.  It is 50 times more potent than morphine.  It was originally manufactured by Janssen Pharmaceutica in 1959 which was acquired by Johnson & Johnson.  It is branded as: Sublimaze, Actiq, Durogesic, Duragesic, Fentora, Matrifen, Subsys, Instanyl, Abstral, Lazanda; with a variety of deployment formulations.  It is often used, in a transdermal patch such as durogesic, to treat severe ongoing pain which can be induced by cancer.  It has followed heroin into the back-street opioid epidemic (Jun 2017).

• Imaging: CT is computerized tomography in which a series of X-ray views taken from many angles are combined by computer processing to create 3-D images.  It is very useful for examining people who have been subject to trauma such as car accidents.  The high dose of radiation is a cause for concern with over use of CT scanning (Jan 2014).  The Banyan Brain Trauma Indicator blood test should help here. 
  , fMRI is functional magnetic resonance imaging.  Seiji Ogawa leveraged the coupling of neuronal circuit activity and blood flow through the associated glial cells to build a 3 dimensional picture of brain cell activity.  As haemoglobin gives up its oxygen to support the neural activity it becomes magnetic and acts as a signal detected by the fMRI.  fMRI easily visualizes the state of activity in the living human brain at millimeter resolution, up to several times a second but it cannot track the time course of neural firing so it is augmented with EEG.  , molecular imaging allows the visualization of cellular function and molecular processes, allowing more precise and earlier diagnosis of disease.  It extends traditional imaging by:
  
  • Using biomarkers, including Nano sensors, which interact chemically with their surroundings, to image particular targets and pathways
    
  • Leveraging deep learning to reduce the required imaging, and target it more effectively
    
  • Providing quantitative data on the imaged process or function enabling Nano medicine.  
  • Extending mass spectrometry with MALDI to allow rapid (relative to sequencing or x-ray crystallography), low cost analysis of proteins, bacteria and viruses.  
  : MALDI is matrix-assisted laser desorption/ionization mass spectrometry.  It generates ions in the gas phase from large molecules.  The sample (a protein, DNA, sugar) is: 1. Mixed with an appropriate matrix material and is deployed to a metal plate.  2. Irradiated with a pulsed laser.  3. Ionized with an ablated gas; and then flowed to an appropriate mass spectrometer.  MALDI is low cost and rapid to perform but it is hard to make quantitatively repeatable.

• Genomics combines recombinant DNA editing with tools: CRISPR; DNA next generation sequencing and bioinformatics  to sequence, assemble and analyse genomes.   and proteomics may: transform screening, testing uses genomic analysis to diagnose genetic disorders - for example Genomic Health's Oncotype DX & Agendia's MammaPrint.  The desire to see the genetic risk factors identified by such tests should depend on the risk * burden * Possibility of intervention.  Early tests look at only single gene mutations, but big data research tools are showing promise with large gene algorithms (Aug 2018).  Genomic testing can be performed direct-to-consumer.  Data is being collated on the genetic components of most diseases to enable more sophisticated diagnosis in the future such as the OPHG (EGAPP initiative), USPSTF recommendations and NCBI (Genetic test registry).  While there is only limited identification of the significant mutations and limited patient bases misdiagnosis is a problem (Aug 2016). 
  , and drug delivery studies how genes affect a person's response to drugs so as to develop personalized drug treatment plans, tailored to a person's specific phenotype.  The process optimizes the treatment process but there are barriers to its deployment:
  • Large scale clinical trials may test 20,000 individuals, but if a toxic response impacts only 0.1% of them there would only be 20 cases found which is often too few to identify the cause of the response.  Instead a process for capturing adverse drug reactions after approval and marketing must be used along with the ability to take a blood sample in these cases.  
  • Simplified studies on a subset of individuals that have the target allele should be cheaper but are unattractive to pharmaceutical companies which typically want to maximize their target market (Aug 2016).  
  • F.D.A. has not required genomic testing for most drug developments.  
  • Health care providers are being slow to use pharmacogenomics.  Often third-party payers are unwilling to reimburse the tests. 
    
  • Transportation to centralized laboratories for genomic testing causes delays which makes some drug therapy applications impractical.  An alternative solution would be to have a patient's EHR contain their genome sequence for immediate genomic implications.

• Can the key mutations be identified? Can the control systems be understood? 
  
• Precision/Personalized medicines is a medical strategy where decisions, practices, and products are tailored to the individual patient.  Research is looking at the impact of providing potentially deleterious genomic testing information to people: The REVEAL study found no increased anxiety induced by hearing that one's genome implied increased risk of developing late onset Alzheimer's disease.  The take-up of personalized medicine benefits from the focus on genomics, enabled by next generation sequencing of DNA, and detailed by the NIH director Francis Collins and includes:
  • NCCN intensive cell therapies
    
  • Direct to consumer genomic testing
    
  • Direct to consumer diagnostics
    
  • Pharmacogenomics tailored drug treatments reducing the risk and cost of adverse drug reactions.   
  : Obesity is an addictive disorder where the brain is induced to require more eating, often because of limits to the number of fat cells available to report satiation (Jul 2016).  Brain images of drug-addicted people and obese people have found similar changes in the brain.  Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors.  Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so.  Obesity is associated with: metabolic syndrome including inflammation, cancer (Aug 2016), high cholesterol, hypertension, type-2-diabetes, asthma and heart disease.  It is suspected that this is contributing to the increase in maternal deaths in the US (Sep 2016).  Obesity is a complex condition best viewed as representing many different diseases, which is affected by the: Amount of brown adipose tissue (Oct 2016), Asprosin signalling by white adipose tissue (Nov 2016), Genetic alleles including 25 which guarantee an obese outcome, side effects of some pharmaceuticals for: Psychiatric disorders, Diabetes, Seizure, Hypertension, Auto-immunity; Acute diseases: Hypothyroidism, Cushing's syndrome, Hypothalamus disorders; State of the gut microbiome.  Infections, but not antibiotics, appear associated with childhood obesity (Nov 2016). 
  mechanism, Immuno-oncology uses the immune system to treat cancer.  Cancer cells often have different molecules on their cell surface.  Studies have shown that genetic signatures of tumors can help predict which patients will benefit from treatment with PD-1 checkpoint inhibitors.  Checkpoint inhibitor based treatments aim to make the immune system target these antigens.  Clinical trial results indicate they are prolonging lives - even if only by a few months.  They have reduced side effects relative to generic chemo therapy.  There are three main strategies: cellular, antibody and cytokine.  
  • Antibody therapies target receptors including CD20, CD274, CD279 and CTLA-4.  These therapies include MABs: Alemtuzumab, Ofatumumab, Rituximab; and may induce checkpoint inhibition.
    
  • Cellular therapies have typically involved removing the immune cells from the blood or a tumor, activating, culturing and then returning them to the patient.  Trials of these CAR and TCR therapies are proceeding, with some significant problems (Jul 2016). 
    
  • Cytokine therapies enhance anti-tumor activity through the cytokine's regulation and coordination of the immune system. 
    
  • Vaccines, including Sipuleucel-T for prostate cancer and BCG, classically a vaccine for tuberculosis, which is used for treating bladder cancer.

• New: Trial process, Pharmaceutical & biotech business model
  
• Can discrete signals be induced that differentiate every cell?  Why would a cancer is the out-of-control growth of cells, which have stopped obeying their cooperative schematic planning and signalling infrastructure.  It results from compounded: oncogene, tumor suppressor, DNA caretaker; mutations in the DNA.  In 2010 one third of Americans are likely to die of cancer.  Cell division rates did not predict likelihood of cancer.  Viral infections are associated.  Radiation and carcinogen exposure are associated.  Lifestyle impacts the likelihood of cancer occurring: Drinking alcohol to excess, lack of exercise, Obesity, Smoking, More sun than your evolved melanin protection level; all significantly increase the risk of cancer occurring (Jul 2016).

• Nanomedicine is the application of nanotechnology to medicine (May 2016, Feb 2019).  Commercial applications are focused on research and clinical tools for drug delivery, therapies, safer and more effective in vivo imaging, neuro-electronic interfaces, other Nano-sensors, and eventually cell repair machines!!  There are issues with determining toxicology etc. 
  will: Reduce the invasiveness of surgery, enhance screening, testing and drug delivery.  
• Expanded scientific conception of the patient: Awareness of the individual is a medical strategy where decisions, practices, and products are tailored to the individual patient.  Research is looking at the impact of providing potentially deleterious genomic testing information to people: The REVEAL study found no increased anxiety induced by hearing that one's genome implied increased risk of developing late onset Alzheimer's disease.  The take-up of personalized medicine benefits from the focus on genomics, enabled by next generation sequencing of DNA, and detailed by the NIH director Francis Collins and includes:

  , neuroscience deals with the structure, development, chemistry, pharmacology, function and pathology of networks of biological neurons. 
  : Dementia is a classification of memory impairment, constrained feelings and enfeebled or extinct intellect.  The most common form for people under 60 is FTD.  Dementia has multiple causes including: vascular disease (inducing VCI) including strokes, head trauma, syphilis and mercury poisoning for treating syphilis, alcoholism, B12 deficiency (Sep 2016), privation, Androgen deprivation therapy (Oct 2016), stress, Parkinson's disease, Alzheimer's disease, and prion infections such as CJD and kuru.  The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system.  It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training.  Dementia appears to develop faster in women than men.   research (Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough. 
    
  • Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016). 
    
  • Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
    
  • BACE inhibitors block an enzyme needed to form amyloid. 
    
  • Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons.  The Tau tangles kill nerve cells.  LMTX is a drug treatment targeted at these tangles. 
    
  • The brain becomes inflamed resulting in the killing of many more nerve cells.  The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable. 
    
  ), Memory (sleep facilitates salient memory formation and removal of non-salient memories.  The five different stages of the nightly sleep cycles support different aspects of memory formation.  The sleep stages follow Pre-sleep and include: Stage one characterized by light sleep and lasting 10 minutes, Stage two where theta waves and sleep spindles occur, Stage three and Stage four together represent deep slow-wave sleep (SWS) with delta waves, Stage five is REM sleep; sleep cycles last between 90-110 minutes each and as the night progresses SWS times reduce and REM times increase.   Sleep includes the operation of synapse synthesis and maintenance through DNA based activity including membrane trafficking, synaptic vesicle recycling, myelin structural protein formation and cholesterol and protein synthesis.  Sleep also controls inflammation (Jan 2019)  Sleep deprivation undermines the thalamus & nucleus accumbens management of pain. 
  ); microbiome, the trillions of bacteria and viruses that live inside higher animals' guts, on their skin etc.  These bacteria and viruses seem to play a role in: immune responses, digesting food, making nutrients, controlling mental health and maintaining a healthy weight.  The signals from the gut microbiota are relayed by major nerve fibers: vagus; to the central nervous system.  The symbiotic relationship must be actively managed.  Human armpits include glands which provide food favoring certain symbionts who build a defensive shield above the skin.  In the human gut: Barriers are setup: Mucus secretions form a physical constraint and provide sites for bacteriophages to anchor and attack pathogenic bacteria; Symbiont tailored nourishment: Plant-heavy food creates opportunities for fibre specialists like Bacteroides thetaiotaomicron; is provided, Selective binding sites are provided, Poisons are deployed against the unwelcome, and Temperature, acidity and oxygenation are managed.    High throughput sequencing allows the characterization of bacterial populations inside guts.  Beginning at birth, as they pass down the birth canal infants are supplied with a microbiome from their mothers.  If they are borne via cesarean they never receive some of the key bacteria: Bifidobaterium infantis which is also dependent on oligosaccharides in breast milk; from their mothers.  A variety of diseases may be caused by changes in the microbiome:
  • Eczema can be related to changes in the skin microbiome. 
    
  • Obesity can be induced by changes to the gut microbiome.  
  • Chronic inflammation
    
  • Allergies
    
  • Type 1 diabetes
    
  , Immune system has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome.  It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier.  It culls species within the microbiome that are expanding beyond requirements.  It destroys invaders who make it into the internal transport networks.  As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap.  The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding.  The immune system consists of two main parts the older non-adaptive part and the newer adaptive part.  The adaptive part achieves this property by being schematically specified by DNA which is highly variable.  By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen).  When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen.  Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. 
  : development is a phase during the operation of a CAS agent.  It allows for schematic strategies to be iteratively blended with environmental signals to solve the logistical issues of migrating newly built and transformed sub-agents.  That is needed to achieve the adult configuration of the agent and optimize it for the proximate environment.  Smiley includes examples of the developmental phase agents required in an emergent CAS.  In situations where parents invest in the growth and memetic learning of their offspring the schematic grab bag can support optimizations to develop models, structures and actions to construct an adept adult.  In humans, adolescence leverages neural plasticity, elder sibling advice and adult coaching to help prepare the deploying neuronal network and body to successfully compete. 
  , operation, extension uses the immune system to treat cancer.  Cancer cells often have different molecules on their cell surface.  Studies have shown that genetic signatures of tumors can help predict which patients will benefit from treatment with PD-1 checkpoint inhibitors.  Checkpoint inhibitor based treatments aim to make the immune system target these antigens.  Clinical trial results indicate they are prolonging lives - even if only by a few months.  They have reduced side effects relative to generic chemo therapy.  There are three main strategies: cellular, antibody and cytokine.

  and disease; Technological extensions: Overtreatment is the application of unnecessary health care.  It is a complex problem:
  • Overtreatment needs to be adaptive.  As people age their medicine levels typically need to be changed.  Often, as in the case of blood pressure, and blood sugar reduction, they should be reduced to avoid inducing falls (Nov 2015).  
  • Patients with chronic diseases, such as type 2 diabetes, often require different treatment settings.  And again these vary with age. 
    
  • Patients who have learned a regime, and been told it was successful, may resist instructions to change it.  Some worry that they will impact their health care provider's treatment performance measures. 
    
  , Mis-treatment, Medication adherence is focused on improving how effectively patients take their medicines.  In the US in 2017 the problem is huge and costly (Apr 2017).  Chronic diseases such as Malaria illustrate the complexity of the task.  A coherent medical network with shared access to EHR should help.  So do blister packs with the days of the week marked.  M-health glow caps with a wireless transmitter that lights up if medication has not been taken as expected.  An improved prescription label is less open to confusion.  Codes on drugs can be scanned by smartphones to initiate download of an informational video.  Smart pillboxes control when pills are dispensed.  Measuring the contents of a medication bottle can alert for intervention if too much or too little is in the bottle.  Drug manufacturers see ways to get closer to the patient: Sanofi Toujeo deployment; Pharmacies are implementing VDS to support medication adherence: Connected Care;
  , Brain computer interfaces; Double blind research and sham procedures: Stents is a small wire cage that can be inserted into an artery to prop it open.  They were introduced as an alternative to bypass surgery in the 1990s.  Stents are expensive.  Medicare payments vary depending on what kind of stent is used and how many, but are generally in the range $10,000 to $17,000 in 2015.   Double blind trials show that stents have no effect on chest pain relief (Nov 2017)

• Systemic understanding of antibiotics are compounds which kill bacteria, molds, etc.  Sulfur dye stuffs were found to be effective antibiotics.  The first evolved antibiotic discovered was penicillin.  Antibiotics are central to modern health care supporting the processes of: Surgery, Wound management, Infection control; which makes the development of antibiotic resistance worrying.  Antibiotics are:
  • Economically problematic to develop and sell. 
    
  • Congress enacted GAIN to encourage development of new antibiotics.  But it has not developed any market-entry award scheme, which seems necessary to encourage new antibiotic R&D. 
    
  • Medicare has required hospitals and SNFs to execute plans to ensure correct use of antibiotics & prevent the spread of drug-resistant infections.  
  • C.D.C. is acting to stop the spread of resistant infections and reduce unnecessary use of antibiotics.  
    
  • F.D.A. has simplified approval standards.  It is working with industry to limit use of antibiotics in livestock. 
    
  • BARDA is promoting public-private partnerships to support promising research.
    
  • Impacting the microbiome of the recipient.  Stool banking is a solution  (Sloan-Kettering stool banking).  
  • Associated with obesity, although evidence suggests childhood obesity relates to the infections not the antibiotic treatments (Nov 2016). 
    
  • Monitored globally by W.H.O.
    
  • Regulated in the US by the F.D.A. who promote voluntary labeling by industry to discourage livestock fattening (Dec 2013).  
  • Customer demands have more effect - Perdue shifts to no antibiotics in premier chickens (Aug 2015).

• Robotics: Robots & sensors, Virtual Reality is the full immersion of a human user into a virtually generated world.  Hence the user is not able to interact or think about the real world at the same time.  The use of sensors detecting the user's skin, eyes, ears, and other state and signal generators for touch, hearing, visuals etc. supports the transportation of the brain into an alternate situation where the user can interact.  As long as the sensors are broadly detecting the state of the user's body and the signals are generated at greater than 60 per second it is a truly real experience.  Unfortunately it is hard to fool gravity so these systems can induce motion sickness.  Virtual reality is likely to be significant in medicine in:
  • Training with new tools including surgical instruments. 
    
  • Remote treatment including surgery where the feedback allows the surgeon to operate robotic instruments experiencing the remote OR. 
    
  , Mind computer interfaces;  
• Pharmaceutical research on NME is a new molecular entity, including: biologics, biosimilars and some other specialty medications.

• Technology change provides the potential to destabilize!  As ever an enterprise dashboard bringing together an overview of process and population analytics is desired.  Christensen, Grossman and Huang argue that EMR refers to electronic medical records which are a synonym of EHR.  EMRs have strengths and weaknesses:
  • The EHR provides an integrated record of the health systems notes on a patient including: Diagnosis and Treatment plans and protocols followed, Prescribed drugs with doses, Adverse drug reactions;
  • The EHR does not necessarily reflect the patient's situation accurately. 
    
  • The EHR often acts as a catch-all.  There is often little time for a doctor, newly attending the patient, to review and validate the historic details. 
    
  • The meaningful use requirements of HITECH and Medicare/Medicaid specify compliance of an EHR system or EHR module for specific environments such as an ambulatory or hospital in-patient setting. 
    
  • As of 2016 interfacing with the EHR is cumbersome and undermines face-to-face time between doctor and patient.  Doctors are allocated 12 minutes to interact with a patient of which less than five minutes was used for recording hand written notes.  With the EHR 12 minutes may be required to update the record!
    
  , Imaging and Molecular diagnostics (nano-materials in medicine May 2016, Feb 2019) will enable disruption of the whole US health care network. 
  
• Big data -
  
• Big data encompasses the IT systems and processes necessary to do population based data collection, management and analysis.  The very low cost, robust, data storage organized by infrastructure: HADOOP; allows digital data to be stored en mass.  Data scientists then apply assumptions about the world to the data, analogous to evolved mechanisms in vision, in the form of algorithms: Precision medicine, Protein folding modeling (Feb 2019) assumes coevolutionary methods can be applied to identify contact points in a protein's tertiary structure.  Rather than depending on averages, analysis at Verisk drills down to specifics and then highlights modeling problems by identifying the underlying CAS.  For the analysis to be useful it requires a hierarchy of supporting BI infrastructure:
  • Analytics utilization and integration delivered via SaaS and the Cloud to cope with the silos and data intensive nature. 
    
  • Analytics tools (BI) for PHM will be hard to develop.  
  • Complex data models must include clinical aspects of the patient specific data, including disease state population wide.

• Could integrate cell phone data with health records refers to electronic medical records which are a synonym of EHR.  EMRs have strengths and weaknesses:
  • The EHR provides an integrated record of the health systems notes on a patient including: Diagnosis and Treatment plans and protocols followed, Prescribed drugs with doses, Adverse drug reactions;
  • The EHR does not necessarily reflect the patient's situation accurately. 
    
  • The EHR often acts as a catch-all.  There is often little time for a doctor, newly attending the patient, to review and validate the historic details. 
    
  • The meaningful use requirements of HITECH and Medicare/Medicaid specify compliance of an EHR system or EHR module for specific environments such as an ambulatory or hospital in-patient setting. 
    
  • As of 2016 interfacing with the EHR is cumbersome and undermines face-to-face time between doctor and patient.  Doctors are allocated 12 minutes to interact with a patient of which less than five minutes was used for recording hand written notes.  With the EHR 12 minutes may be required to update the record!

  through Medicare Advantage (MA) is a private provider administered health insurance plan providing access to Medicare benefits.  It was originally enacted as part of BBA Medicare + Choice or Part C plans.  The government funded the plan with an annual fee, based on age and severity of the subscriber's medical conditions, rather than FFS.  When a Medicare eligible person enrolls in a MA plan the government pays the private provider a set amount each month.  The participant pays the Medicare part B premium and if required a part C premium each month.  The MA plans offer a PCP who coordinates care.  And the plans have an annual limit on out-of-pocket expenses unlike traditional Medicare.  When they obtain treatment they will have to pay a copayment which may be quite high for some specialists.  It is the health plan's responsibility to contract the physician network that will provide the care, leaving the risk with the insurer.  About 36% of Medicare beneficiaries are enrolled with Medicare Advantage by 2019.  The ACA introduced quality outcome and patient satisfaction based differential payments into MA.  To measure the performance it added a five-star quality rating scheme.  MA plans report their quality and patient satisfaction data to CMS annually and based on the results are awarded one to five stars.  The highest rated plans are provided with large additional payments.  It was assumed that subscribers would shift to the highest rated plans and the other plans would improve or drop out of MA.  And the ACA eliminated subsidies which the federal government used to establish Medicare Advantage.  However, the Obama administration has used a $8.5 Billion demonstration project to maintain this funding.  It is intended that it will eventually taper off so that the cost of Medicare Advantage coverage will be equivalent to standard Medicare. 
  changes, affecting the costly half of Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS.  Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage.  It includes:
  
  • Benefits
  • Part A: Hospital inpatient insurance.  As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization.  Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital. 
    
  • Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
    
  • Part C: Medicare Advantage 
  • Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices. 
    
  • Eligibility
    
  • All persons 65 years of age or older who are legal residents for at least 5 years.  If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived.  Medicare is legislated to become the primary health plan. 
    
  • Persons under 65 with disabilities who receive SSDI. 
    
  • Persons with specific medical conditions:
  • Have end stage renal disease or need a kidney transplant. 
    
  • They have ALS. 
    
  • Some beneficiaries are dual eligible. 
    
  • Part A requires the person has been admitted as an inpatient at a hospital.  This is constrained by a rule that they stay for three days after admission.  
    
  • Sign-up
  • Part A has automatic sign-up if the person is drawing social security.  Otherwise the person must sign-up for Part A and Part B. 
    
  • Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office.  But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July.  Incremental yearly 10% penalties apply for not signing up at 65.  These penalties apply to all subsequent premiums.

  , Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough. 
    
  • Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016). 
    
  • Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
    
  • BACE inhibitors block an enzyme needed to form amyloid. 
    
  • Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons.  The Tau tangles kill nerve cells.  LMTX is a drug treatment targeted at these tangles. 
    
  • The brain becomes inflamed resulting in the killing of many more nerve cells.  The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable. 
    
  , Parkinson's corresponds to the breakdown of certain interneurons in the brain.  It is not fully understood why this occurs.  Dopamine system neuron breakdown generates the classical symptoms of tremors and rigidity.  In some instances an uncommon LRRK2 gene mutation confers a high risk of Parkinson's disease.  In rare cases Italian and Greek families are impacted in their early forties and fifties resulting from a single letter mutation in alpha-synuclein which alters the alpha-synuclein protein causing degeneration in the substantia nigra, after a build up of Lewy bodies in the neurons.  But poisoning from MPTP has also been shown to destroy dopamine system neurons.  DeLong showed that MPTP poisoning results in overactivity in the subthalamic nucleus.  People who have an appendectomy in their 20s are at lower risk of developing Parkinson's disease.  The Alpha-synuclein protein is known to build up in the appendix in association with changes in the gut microbiome.  This buildup may support the 'flow' of alpha-synuclein from the gut along neurons that route to the brain.  Paraquat has also been linked to Parkinson's disease.  Parkinson's disease does not directly kill many sufferers.  But it impacts swallowing which encourages development of pneumonia through inhaling or aspirating food.  And it undermines balance which can increase the possibility of falls.  Dememtia can also develop.  Treatment with deep-brain stimulation, after surgical implantation of electrodes in the subthalamic nucleus removes the symptoms of Parkinson's disease in some patients. 
  , CHF is congestive heart failure which occurs when the heart is unable to generate enough blood flow to meet the body's demands.  There are two main types: failure due to left ventricular dysfunction and abnormal diastolic function increasing the stiffness of the left ventricle and decreasing its relaxation.  Heart expansion in CHF distorts the mitral valve which exacerbates the problems.  MitraClip surgery trials found effective in correcting the mitral valve damage (Sep 2018).  Treatments include: digoxin; , rheumatoid Arthritis is an autoimmune disorder where the immune system attacks the joints and can generate inflammation around the lungs and heart.  It can be treated with: Enbrel, Humira, Ilaris, Xeljanz;
  , and some cancers is the out-of-control growth of cells, which have stopped obeying their cooperative schematic planning and signalling infrastructure.  It results from compounded: oncogene, tumor suppressor, DNA caretaker; mutations in the DNA.  In 2010 one third of Americans are likely to die of cancer.  Cell division rates did not predict likelihood of cancer.  Viral infections are associated.  Radiation and carcinogen exposure are associated.  Lifestyle impacts the likelihood of cancer occurring: Drinking alcohol to excess, lack of exercise, Obesity, Smoking, More sun than your evolved melanin protection level; all significantly increase the risk of cancer occurring (Jul 2016).

  • Plaques started to gather in the coronary arteries and grew until no blood flow was possible.  If this is true it makes sense to preventatively treat the buildup with angioplasty. 
    
  • Plaques form anywhere in the body due to atherosclerosis and then break up and get lodged in the coronary artery and start to clot.  If this is true it makes sense to preventatively limit the buildup of plaques with drugs like statins or PCSK9 inhibitors.

  , judged by changes in the entorinal cortex is a main limbic association area between the hippocampus and the neocortex, in the medial temporal lobe.  It is a hub for memory and navigation: location awareness is supported by grid cells.  It is the first brain area impacted in Alzheimer's disease. 
  , hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory.  It includes the dentate gyrus.  Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation.  The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle.  Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information.  During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation.  It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories.  The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point.  Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits.  It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky.  Prolonged stress makes the hippocampus atrophy.  He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different.  Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease.  It directly signals area 25.

  transcription factor are enzymes which associate with a transcription complex to bind to the DNA and control its transcription and hence translation into proteins.  The regulation of DNA transcription and protein synthesis are reviewed by Tsonis.  Transcription factors allow environmental state to become reflected in the control of DNA transcription.  Transcription factors can regulate multiple genes, allowing network effects & multiple transcription factors can regulate a gene allowing sophisticated control processes.  In AWF the transcription, translation and deployment infrastructure of the eukaryotic cell has been abstracted in a codelet based implementation. 
  binding motifs and signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy. 
  links with ApoE4 is a gene variant which produces the E4 variant of APOE.  It is a risk-factor for late-onset sporadic Alzheimer's disease.  Being homozygote for E4 does not imply getting Alzheimer's but does increase the risk 20 fold.  ApoE2 may reduce the risk of Alzheimer's.  It appears that ApoE4 differentially affects women.  Apoe4 is known to be broken down into fragments which impare mitochondrial operation.  It also promotes amyloid plaque buildup.  Therapies are being developed based on small molecules which reshape ApoE4 to be more like ApoE3 reducing the breakdown.

It seems likely that after remaining dormant for years the virus is a relatively small capsule containing genetic material which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins.  The relationship with the host is short term, relative to parasites, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it.

  • Makes it easier to learn a fear association and to consolidate it into long-term memory.  Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala.  And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces.  Accuracy of assessing emotions from faces suffers.  A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand.  The activation of the amygdala seems to determine how the hippocampus responds.

  ) & generates an immune has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome.  It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier.  It culls species within the microbiome that are expanding beyond requirements.  It destroys invaders who make it into the internal transport networks.  As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap.  The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding.  The immune system consists of two main parts the older non-adaptive part and the newer adaptive part.  The adaptive part achieves this property by being schematically specified by DNA which is highly variable.  By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen).  When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen.  Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. 
  response that stimulates plaques which kill neurons, specialized eukaryotic cells include channels which control flows of sodium and potassium ions across the massively extended cell membrane supporting an electro-chemical wave which is then converted into an outgoing chemical signal transmission from synapses which target nearby neuron or muscle cell receptors.  Neurons are supported by glial cells.  Neurons include a:
  • Receptive element - dendrites
    
  • Transmitting element - axon and synaptic terminals.  The axon may be myelinated, focusing the signals through synaptic transmission, or unmyelinated - where crosstalk is leveraged.

• Is there a conflict between Christensen's disruption of CABG by Angioplasty and ProvenCare's bundled pricing for CABG refers to Coronary artery bypass grafting, a treatment provided by cardiac surgeons.  Lower cost angioplasty has disrupted this business but both have been provided by general hospitals.  Christensen argues angioplasty should be part of a radically lower cost business which should disrupt the solution business of the general hospital.  .  
• Can historic data describing pre-disruption processes and associated VDS analyzed with additional IT infrastructure help effectively model the future price of bundled offers?  It didn't help much in high tech.  So these arguments are assuming no disruption.  
• Payers include four types:
  • From the 1930s the insurers Blue Cross and Blue Shield catalyzed health care activity by paying a daily per diem to hospitals for the diagnoses and treatments the hospital's dispensed.  At their inception in 1966 Medicare and Medicaid followed this reimbursement model. 
  • From 1983 Medicare and Medicaid switched to the PPS reimbursement mechanism.  This forced alignment of the supplier, diagnosis, treatment, billing and reimbursement processes.  The health care network is still structurally aligned around PPS.  Under scrutiny of ProPAC and its successor MedPAC,  as well as pressure of the BBA after 1997, the payments per DRG have been steadily reduced until it was below the cost of care, forcing hospitals to seek margin from their other payers.  Medicare outlier payments benefited hospitals that inflated charges and thus became eligible. 
    
  • Employers as they experienced cost shifting from the hospital's increased product charges moved their employees over to managed care based payment. 
  • Private payers pay hospitals directly for their diagnosis and treatment.  Typically this group has little power.  There are default rates for private payers - typically 40% of billed charges that are not covered by a fixed payment or a fee schedule.  For the uninsured poor until 2004 they obtained little discount on the hospital's chargemaster list price, because insurers and CMS required to be charged the lowest value offered to any patients.  Medicare has now relaxed this constraint. 
  are buying up bundled payment analytics companies.  They need to look across their environment to understand trends.  This could leave health systems (providers) dependent on payers for developing effective marketing and bundling strategies!

• Electronic medical records (EMR refers to electronic medical records which are a synonym of EHR.  EMRs have strengths and weaknesses:
  • The EHR provides an integrated record of the health systems notes on a patient including: Diagnosis and Treatment plans and protocols followed, Prescribed drugs with doses, Adverse drug reactions;
  • The EHR does not necessarily reflect the patient's situation accurately. 
    
  • The EHR often acts as a catch-all.  There is often little time for a doctor, newly attending the patient, to review and validate the historic details. 
    
  • The meaningful use requirements of HITECH and Medicare/Medicaid specify compliance of an EHR system or EHR module for specific environments such as an ambulatory or hospital in-patient setting. 
    
  • As of 2016 interfacing with the EHR is cumbersome and undermines face-to-face time between doctor and patient.  Doctors are allocated 12 minutes to interact with a patient of which less than five minutes was used for recording hand written notes.  With the EHR 12 minutes may be required to update the record!

• Accountable Care Organizations (ACO is an Accountable Care Organization. These are accredited bundles of companies which together try to offer Dartmouth-Hitchcock like business models (Dec 2015, Sep 2016) focused on wellness, improving the provision of primary care to a large group of Medicare patients, and rewarding doctors for preventing problems.  Advocate health illustrates the idea.  Robert Pearl notes that the transition is difficult: hospitals that find their efficiency improving should reduce the number of doctors they utilize.  But any doctors that are pushed out of the ACO will likely take their patients with them, undermining the revenues that support the FFV business.  The ACA regulates qualification to be a Medicare ACO.  Individual organizations within a Medicare shared savings ACO continue to submit their own claims and are paid by Medicare for FFS.  But the ACO is eligible for shared savings.  Within the shared savings program the CMS innovation center has setup advanced payment ACOs.  As an alternative to shared savings, in a Pioneer ACO, over time 50% of the FFS payments flow directly to the ACO as a bundled payment.  CMS has established quality measures for ACOs for Medicare.  The CMS program's purpose is to reward providers for reducing total cost of care for patients through prevention, disease management, and coordination. 
  
  • CMS initiated its Physician Group Practice Demonstration in 2005.  By 2008 the congressional budget office reported on Bonus-eligible organizations. 
    
  • CMS defines ACOs as organizations that "create incentives for health care providers to work together to treat an individual patient across care settings - including doctors' offices, hospitals and long-term care facilities."
  • CMS has developed APMs which include ACOs, and advanced APMs where the ACOs must be risk bearing. 
    
  • CMMI accepts providers' proposals to test various payment systems including shared savings and partial capitation.  
  • Private market ACOs have formed including: Providence Health & Services, Blue Shield California, Anthem Blue Cross, United Health Care, BCBS Minnesota, BCBS Illinois, Humana, CIGNA, Main Health Management Coalition, BCBS Massachusetts, Aetna.  
  ) need to be integrated.  In 2013 they are requiring interoperation of vendors of medical and radiation oncology with other technologies.  
• Premier suggests that ACOs can be constructed contractually without expanding transaction costs and undermining strategic coherence which would make them become uncompetitive - but this claim seems unlikely to be legitimate.  The transaction costs are likely to be higher and the independent businesses must either become phenotypically aligned, or remain strategically in conflict. 
  
• Startup Aledade demonstrates a way to integrate the PCP is a Primary Care Physician.  PCPs are viewed by legislators and regulators as central to the effective management of care.  When coordinated care had worked the PCP is a key participant.  In most successful cases they are central.  In certain Medicare ACO models (Pioneer) PCPs are committed to achieve meaningful use requirements.  Working against this is the: replacement of diagnostic skills by technological solutions, low FFS leverage of the PCP compared to specialists, demotivation of battling prior authorization for expensive treatments.

• Role based security infrastructure is seen as a key enabler of ACOs.  Also seen as key are clinical data warehouses, corporate wide reporting and peer group benchmarking. 
  
• Public Health Information Exchanges (HIE a Health Information Exchange is responsible for the transmission of health care-related data among facilities, health information organizations and government agencies according to national standards.  They are designed to address legal, organizational and technical challenges that would otherwise impede the sustainability of health information interchange.  An HIE is a component of the HIT.  It must enable reliable and secure transfer of data among diverse systems and facilitate access and retrieval.  The two main types are private and public exchanges.  Private exchanges may be able to leverage homogeneous IT infrastructure to facilitate data sharing.  Public exchanges are likely to be heterogeneous.  RHIO provide the regional organizations to support such HIE.  They are there to ensure that infrastructure amplification initiates.  The government will ensure that low healthcare density areas are served by public HIE infrastructure.  Both centralized and federated technical solutions were initially considered for implementation by the RHIOs for deploying HIE as specified in the Markle Foundation's NHIN common framework.  Common framework clients such as appropriately architected HIE use SOAP messaging to interact with their local SNO's ISB and RLS.  The HIE SOAP query transactions follow the HL7 Query Model.  Alternatively some HIE's are now using direct messaging to support interoperation.  HIE deployment goals have been phased (1 - supporting care transitions, 2 - Quality and care management, 3 - Population health).  Some HIEs will support "EHR-lite" as part of their functionality.  HIE does not yet solve some difficult challenges:
  • Safeguarding the security of health information.  Currently HIEs conforming to the common framework only provide locations of clinical data held remotely.  
  • Providing effective life cycle management.  The HIE is dependent on the local set of entities to provide updates that match the current state of the entity data.

  .  But as of 2013 deployment in key states is still primitive.  Indiana has one of the most developed and studied HIE projects (IHIE is the state wide Indiana Health Information Exchange which leverages the IT and informatics team at the INPC.  It includes clinical and administrative claims data to support electronic delivery of test reports to physician offices.  It also maintains a report card and incentives on established quality measures to physicians, practice groups, payers and employers.  ).

  1. 2011-2012 Data capture and sharing - Criteria focus on electronically capturing health information in a standardized format.  Using that information to track key clinical conditions.  Communicating that information for care coordination processes.  Initiating the reporting of clinical quality measures and public health information.  Using information to engage patients and their families in their care.  Achieving meaningful use stage 1 requires meeting all core and selected menu objectives. 
     
  2. 2014 Advance clinical processes - More rigorous health information exchange requirements.  Increased requirements for e-prescribing and incorporating lab results.  Electronic transmission of patient care summaries across multiple settings.  More patient-controlled data.  A patient portal is required.  CMS hospital core measures, CMS hospital menu set measures, NPRMs of stage 2 meaningful use and certification criteria have been announced (2013).  
  • MU2 requires EHR systems to support direct messaging to send PHI to registered users. 
    
  3. 2016 Improved outcomes - Improving quality, safety, and efficiency, leading to improved health outcomes.  Decision support for national high-priority conditions.  Patient access to self-managed tools.  Access to comprehensive patient data through patient-centered HIE.  Improving population health.

• Closed loop medication administration is focused on improving how effectively patients take their medicines.  In the US in 2017 the problem is huge and costly (Apr 2017).  Chronic diseases such as Malaria illustrate the complexity of the task.  A coherent medical network with shared access to EHR should help.  So do blister packs with the days of the week marked.  M-health glow caps with a wireless transmitter that lights up if medication has not been taken as expected.  An improved prescription label is less open to confusion.  Codes on drugs can be scanned by smartphones to initiate download of an informational video.  Smart pillboxes control when pills are dispensed.  Measuring the contents of a medication bottle can alert for intervention if too much or too little is in the bottle.  Drug manufacturers see ways to get closer to the patient: Sanofi Toujeo deployment; Pharmacies are implementing VDS to support medication adherence: Connected Care;
  , clinical decision support protocols and CPOE is computerized provider order entry.  Certified EHR technologies are required to support CPOE ordering of medications, laboratory and radiology/imaging.  CPOE can provide physician support reducing medication errors significantly, as illustrated at Beth Israel.  ISVs such as Surescripts can then route the order to the pharmacy.   has reached 14% in 2013.

• Molecular imaging allows the visualization of cellular function and molecular processes, allowing more precise and earlier diagnosis of disease.  It extends traditional imaging by:
  
  • Using biomarkers, including Nano sensors, which interact chemically with their surroundings, to image particular targets and pathways
    
  • Leveraging deep learning to reduce the required imaging, and target it more effectively
    
  • Providing quantitative data on the imaged process or function enabling Nano medicine.

• mass spectrometry with MALDI  is matrix-assisted laser desorption/ionization mass spectrometry.  It generates ions in the gas phase from large molecules.  The sample (a protein, DNA, sugar) is: 1. Mixed with an appropriate matrix material and is deployed to a metal plate.  2. Irradiated with a pulsed laser.  3. Ionized with an ablated gas; and then flowed to an appropriate mass spectrometer.  MALDI is low cost and rapid to perform but it is hard to make quantitatively repeatable.

• Dementia is a classification of memory impairment, constrained feelings and enfeebled or extinct intellect.  The most common form for people under 60 is FTD.  Dementia has multiple causes including: vascular disease (inducing VCI) including strokes, head trauma, syphilis and mercury poisoning for treating syphilis, alcoholism, B12 deficiency (Sep 2016), privation, Androgen deprivation therapy (Oct 2016), stress, Parkinson's disease, Alzheimer's disease, and prion infections such as CJD and kuru.  The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system.  It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training.  Dementia appears to develop faster in women than men.  
  
• Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:

  ; with Alzheimer's disease is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.

  , judged by changes in the entorinal cortex is a main limbic association area between the hippocampus and the neocortex, in the medial temporal lobe.  It is a hub for memory and navigation: location awareness is supported by grid cells.  It is the first brain area impacted in Alzheimer's disease. 
  , hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory.  It includes the dentate gyrus.  Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation.  The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle.  Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information.  During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation.  It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories.  The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point.  Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits.  It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky.  Prolonged stress makes the hippocampus atrophy.  He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different.  Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease.  It directly signals area 25.

  transcription factor are enzymes which associate with a transcription complex to bind to the DNA and control its transcription and hence translation into proteins.  The regulation of DNA transcription and protein synthesis are reviewed by Tsonis.  Transcription factors allow environmental state to become reflected in the control of DNA transcription.  Transcription factors can regulate multiple genes, allowing network effects & multiple transcription factors can regulate a gene allowing sophisticated control processes.  In AWF the transcription, translation and deployment infrastructure of the eukaryotic cell has been abstracted in a codelet based implementation. 
  binding motifs and signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy. 
  links with ApoE4 is a gene variant which produces the E4 variant of APOE.  It is a risk-factor for late-onset sporadic Alzheimer's disease.  Being homozygote for E4 does not imply getting Alzheimer's but does increase the risk 20 fold.  ApoE2 may reduce the risk of Alzheimer's.  It appears that ApoE4 differentially affects women.  Apoe4 is known to be broken down into fragments which impare mitochondrial operation.  It also promotes amyloid plaque buildup.  Therapies are being developed based on small molecules which reshape ApoE4 to be more like ApoE3 reducing the breakdown.

It seems likely that after remaining dormant for years the virus is a relatively small capsule containing genetic material which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins.  The relationship with the host is short term, relative to parasites, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it.

  • Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment! 
    
  • Activates the integration between the thalamus and amygdala. 
    
  • Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful. 
    
  • BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning. 
    
  • Makes it easier to learn a fear association and to consolidate it into long-term memory.  Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala.  And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces.  Accuracy of assessing emotions from faces suffers.  A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand.  The activation of the amygdala seems to determine how the hippocampus responds.

  for sickle-cell anemia is a recessive single gene disease where the sufferer's hemoglobin causes the red blood cells to distort.  It is a side effect of the evolved protection from malaria provided by sickle cell trait.  Potential treatments include gene therapy and drugs that block the sickling of red blood cells.  Carrier screening was undermined by there being no effective prenatal test limiting the benefit of the information and because the white doctors were not trusted by their black patients.  In the future iPS cells could have the problem mutations replaced with ex vivo gene therapy. 
  in trials: Boston Children's, Northwestern; resulting in patients with no symptoms, mid trail.  Red blood stem cells is a biological cell which is partly or wholly undifferentiated.  A totipotent cell can generate a complete embryo and placenta.  Embryos include pluripotent cells which can generate any tissue in the body.  Adult humans' cells have turned off this ability but still include multipotent stem cells that differentiate into multiple cell types.   Typically a cell's local environment will have the signals required for it to obtain context and differentiate appropriately.  This will include both the external environment and the internal state of the cell which has replicated from a parent and obtained its epi-genetic state.   So introduction of undifferentiated stem cells into an injured area is not likely to have either aspect of the environment suitable.  Consequently development is aiming to encourage differentiation to progenitor cells for the damaged region.  This requires delivering the cells to the appropriate part of the body.  To avoid rejection by the immune system techniques aim to use cell lines developed from the patient's cells.  The techniques to generate these cell lines include: SCNT, iPS.  Possible mechanisms of stem cell therapy are: Generation of new differentiated cells, Stimulation of growth of new blood vessels to repopulate damaged regions, Secretion of growth factors, Treatment of diabetes (1 and 2) with addition of pancreatic cells, Assistance of other mechanisms; are removed from the bone marrow, the sickle-cell gene mutation is removed from the DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains.  DNA naturally forms into helical pairs with the side chains stacked in the center of the helix.  It is a natural form of schematic string.  The purines and pyrimidines couple so that AT and GC pairs make up the stackable items.  A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence.  Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema.  To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. 
  and the stem-cells are flowed back into the body, where they must reenter the bone marrow for the therapy to work.  Genetic update can use newly discovered large viral vector.   An alternative to gene therapy uses a gene edit using CRISPR is clustered replicating interspersed silent palindromic repeats; a technique for exact targeting, cutting and editing of DNA based on leveraging bacterial enzymatic defenses against viruses generalized to any DNA sequence in a prokaryotic or eukaryotic cell.  It was identified during studies of a bacterial adaptive immune system.  In that system bacterial proteins grab parts of a virus that has infected them and record it within the palindromic structures that mark an array of inserted viral DNA used as a log persisted over generations.  If a new infection occurs the viral DNA is compared with the sequences and if a match exists the CAS proteins break up the viral DNA initiating its destruction.  This bacterial system was then updated and repurposed by the researchers to support targeted genetic engineering.  As explained by Dr. Doudna, the CRISPR proteins and the 20 nucleotide RNA template migrate into the nucleus where they rapidly target DNA which complements the RNA template and the Cas9 enzyme performs the edits.  Being a bacterial system CRISPR Cas9 does not target eukaryotic heterochromatic DNA well.  It is not fully understood how they find the target sequence so quickly.  It has been shown that Cas9 will bind to sites with a 5-8 base match but then it releases rapidly without cutting.  To cut, Cas9 has to reconfigure, which does not occur in the mismatch situations.  .  Another treatment strategy blocks the genetic transition from fetal to adult hemoglobin: fetal does not sickle.  NIH is the National Institute of Health, Bethesda Maryland.  It is the primary federal agency for the support and conduct of biomedical and behavioral research.  It is also one of the four US special containment units of the CDC.   is launching a funding program 'Cure Sickle-Cell' (Jan 2019)

• Irisin is a hormone which stimulates white adipose (fat) tissue to turn brown.  Irisin is created in working muscles in mice.  After entering the bloodstream it migrates to other tissues, in particular adipose cells where it signals a pathway that promotes UCP1 generation and causes some of the white adipose cells to turn brown.  Brown adipose: Burns calories, Controls insulin and blood sugar; and reduces the risk of type-2-diabetes.   Irisin signals white adipose stem cells to become bone cells.  Irisin has no apparent effect on brown adipose cells.  When irisin was injected into mice being fed a high fat, high calorie diet it inhibited them becoming obese.

  signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy.

• Novartis & University of Cambridge researchers find P53 is a tumor suppressor which improves the specificity of transcription's DNA binding and promotes the transcriptional activity of E2F.  P53's activity is controlled by phosphorylation by cyclin Cdk complexes allowing indirect control of the cell cycle.  Among the many genes controlled by p53 are cyclin genes, genes for an inhibitor of cyclin-dependent kinases (Cdk), and the bax gene, which promotes apoptosis.  p53 can thus promote cell proliferation.  It can drive cells into apoptosis.  But it can also stop cell proliferation by arresting the cell cycle.  Normally there is a dynamic balance between proliferation of cells and their death.  In cancer proliferation may become unregulated due to oncogenic mutations or over expression of key regulatory signalling G proteins such as Ras.  Mutations of the p53 suppressor gene are the most frequent suppressor gene mutations in human cancers.  Elephants like humans, have a relatively low buildup of cancer with age.  Elephant's cells have twenty copies of p53 gene pairs which ensure cells with damaged DNA go into apoptosis blocking cancer onset.  P53 has been shown to be involved in irregular brain cell activity in epilepsy and ASD.

• Juno Immuno-oncology uses the immune system to treat cancer.  Cancer cells often have different molecules on their cell surface.  Studies have shown that genetic signatures of tumors can help predict which patients will benefit from treatment with PD-1 checkpoint inhibitors.  Checkpoint inhibitor based treatments aim to make the immune system target these antigens.  Clinical trial results indicate they are prolonging lives - even if only by a few months.  They have reduced side effects relative to generic chemo therapy.  There are three main strategies: cellular, antibody and cytokine.  
  • Antibody therapies target receptors including CD20, CD274, CD279 and CTLA-4.  These therapies include MABs: Alemtuzumab, Ofatumumab, Rituximab; and may induce checkpoint inhibition.
    
  • Cellular therapies have typically involved removing the immune cells from the blood or a tumor, activating, culturing and then returning them to the patient.  Trials of these CAR and TCR therapies are proceeding, with some significant problems (Jul 2016). 
    
  • Cytokine therapies enhance anti-tumor activity through the cytokine's regulation and coordination of the immune system.

  CAR is chimeric antigen receptor.  Killer T lymphocytes are genetically engineered to produce a novel protein, composed of pieces from different parts of the immune system such as: antibody components to construct a new receptor binding site on the T cell that targeted an antigen exposed on the cell surface of cancer cells, and two receptor associated signals that switch the T-cell into kill mode and sustain it in that mode.  Small clinical trials of CAR-T cells have shown substantial remissions among patients with various blood cancers (Aug 2016, Jul 2017, Oct 2017, Nov 2017).  But there are severe side effects.  -T trial for adult ALL is acute lymphocytic/lymphoblastic leukemia.  The cancer starts in the lymphocytes of the bone marrow.  Too many lymphocytes are produced instead of mature white blood cells.  In 2010 combination chemotherapy, including 6-mercaptopurine, cures 85 to 90% of children suffering from ALL.   suspended after deaths (Jul 2016)
• BMS checkpoint inhibitors release the immune system's checkpoints: PD-1, CTLA-4; on attacking host cells: by 1) stopping T-cell division and 2) reducing their life spans.  They are used in immuno-oncology where, in 2016: They are approved for treatment of: Advanced melanoma, HL, lung, kidney, liver cancer; They have a general success rate of 20 - 40% and higher for melanoma.   Checkpoint inhibitors work best for tumors that have many mutations: melanomas, lung and bladder cancers.  They are enhanced by adjunct treatments that kill tumor cells generating debris to stimulate the immune system.  The drugs include: ipilimumab (CTLA-4 inhbition), nivolumab, pembrolizumab, atezolizumab (PD-1 inhibitors);  They are costly and often have high copayments.  They cause auto-immune side effects including inflammation, rheumatoid arthritis and damage to glands: Adrenal, Thyroid, Pituitary.  Powerful steroids such as prednisone can help reduce the inflammation.  Damaged glands require sustained hormone treatment.  Checkpoint inhibitor research is funded by the CRI.  cause heart damage in rare cases Vanderbilt cardio-oncology/Brigham & Women's find (Nov 2016)
  
• Active surveillance is an approach to early-stage prostate cancer which replaces treatment, such as surgery or radiation, with monitoring to ensure the cancers aren't growing rapidly.  It started to be used in about 2000 and so will take time to build a predictive history of the success of the regimen (10 year longitudinal study results Sep 2016).  Active surveillance treatements include: Oncotype DX, PSA, STHLM3; of prostate cancer is cancer of the prostate gland.  Genomics detected several common DNA variants associated with increased risk of prostate cancer.  Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8.  The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%.  The high risk variants occur more frequently in African-American men than European or Asians.  African-Americans die from prostate cancer at more than twice the rate of Europeans.  Research in mice may explain a link between obesity and prostate cancer (Jan 2018).  The average diagnosis is at age 66.  Worldwide in 2012 there were 1.1 million cases from which 307,000 died.  A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects.  Various classically defined types of cancer can occur.  The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid.  Epithelial cell differentiation potency makes these significant cancer agents.  Other very rare types of cancer that can start in the prostate are:

• Calico aging process researchers, Kenyon & Bohnert, identify sperm signalled, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy.

• Atopic dermatitis, is also called eczema is a long lasting inflammation of the skin.  It can be successfully treated with dupilumab.   (Eczema) biologic are drugs made in living cells.  Typically they are proteins developed using genetic engineering to develop the cellular host, and to customize animal source, DNA to produce human target proteins.  Such biologics partially solve the problem of previous protein sources, extracted from animals or human sources, of contamination and immune responses.  The strategy is very effective for blood transported proteins such as antibodies (MABs), hormones and blood factors.  But intra-cellular proteins still demand delivery and accurate cell targeting.  This creates analogous problems to those of gene therapy. 
  MAB as a terminator in medication names indicates the drug is a monoclonal antibody biologic.   drug treatment dupilumab is a monoclonal antibody which blocks two immune system pathways: interleukin 4 and interleukin 13; that are over produced in atopic dermatitis, by binding to the alpha subunit of the interleukin-4 receptor.  It was developed by Regeneron and marketed as Dupixent.   (Dupixent) has successful trials (Oct 2016).

Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:

  , judged by changes in the entorinal cortex is a main limbic association area between the hippocampus and the neocortex, in the medial temporal lobe.  It is a hub for memory and navigation: location awareness is supported by grid cells.  It is the first brain area impacted in Alzheimer's disease. 
  , hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory.  It includes the dentate gyrus.  Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation.  The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle.  Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information.  During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation.  It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories.  The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point.  Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits.  It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky.  Prolonged stress makes the hippocampus atrophy.  He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different.  Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease.  It directly signals area 25. 
  , promoter enrichments for C2H2 zink finger is a large set of finger like binding domains in mammalian transcription factors with a Cys2-His2 (C2H2) fold group, which can bind in the major groove of DNA. 
  transcription factor are enzymes which associate with a transcription complex to bind to the DNA and control its transcription and hence translation into proteins.  The regulation of DNA transcription and protein synthesis are reviewed by Tsonis.  Transcription factors allow environmental state to become reflected in the control of DNA transcription.  Transcription factors can regulate multiple genes, allowing network effects & multiple transcription factors can regulate a gene allowing sophisticated control processes.  In AWF the transcription, translation and deployment infrastructure of the eukaryotic cell has been abstracted in a codelet based implementation. 
  binding motifs and signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy. 
  links with ApoE4 is a gene variant which produces the E4 variant of APOE.  It is a risk-factor for late-onset sporadic Alzheimer's disease.  Being homozygote for E4 does not imply getting Alzheimer's but does increase the risk 20 fold.  ApoE2 may reduce the risk of Alzheimer's.  It appears that ApoE4 differentially affects women.  Apoe4 is known to be broken down into fragments which impare mitochondrial operation.  It also promotes amyloid plaque buildup.  Therapies are being developed based on small molecules which reshape ApoE4 to be more like ApoE3 reducing the breakdown.

It seems likely that after remaining dormant for years the virus is a relatively small capsule containing genetic material which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins.  The relationship with the host is short term, relative to parasites, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it. 
  activates (stressor is a multi-faceted condition reflecting high cortisol levels.  Dr. Robert Sapolsky's studies of baboons indicate that stress helps build readiness for fight or flight.  As these actions occur the levels of cortisol return to the baseline rate.  A stressor is anything that disrupts the regular homeostatic balance.  The stress response is the array of neural and endocrine changes that occur to respond effectively to the crisis and reestablish homeostasis.

  • Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment! 
    
  • Activates the integration between the thalamus and amygdala. 
    
  • Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful. 
    
  • BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning. 
    
  • Makes it easier to learn a fear association and to consolidate it into long-term memory.  Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala.  And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces.  Accuracy of assessing emotions from faces suffers.  A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand.  The activation of the amygdala seems to determine how the hippocampus responds.

• Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause.

• Syngenta's Paraquat is NN-dimethyl-44-bipyridinium dichloride, a systemic weed killer, used on oranges, coffee and suger cane, manufactured and sold by the Swiss pesticide company Syngenta.  It is banned in the EU, but still allowed to be sold and used in the US.  Drinking even a sip can be lethal.  Recent research by the NIH links paraquat to Parkinson's disease.  The 2011 research found Iowa and North Carolina farmers and family members that handled paraquat or rotenone were 2.5 times more likely to develop Parkinson's disease.  A 2012 study found paraquat increased the likelihood 11 fold for people with certain genetic variations.  The link is disputed by Syngenta.

• Memories in the brain includes functionally different types: Declarative, or explicit, (episodic and semantic), Implicit, Procedural, Spatial, Temporal, Verbal; Hebb suggested that glutamate receptive neurons learn by (NMDA channel based) synaptic strengthening: short term memory.  This was shown to happen for explicit memory formation in the hippocampus.  This strengthening is sustained by subsequent LTP.  The non-real-time learning and planning processes operate through consciousness using the working memory structures, and then via sleep, the salient ones are consolidated while the rest are destroyed and garbage collected.   actively destroyed in fruit flies using Rac is a class of small monomeric GTP-binding proteins including Rac1 and Rac2.  Rac GTPases are implicated in memory removal (Feb 2010) and control of cytoskeleton assembly.

• Purpose of sleep facilitates salient memory formation and removal of non-salient memories.  The five different stages of the nightly sleep cycles support different aspects of memory formation.  The sleep stages follow Pre-sleep and include: Stage one characterized by light sleep and lasting 10 minutes, Stage two where theta waves and sleep spindles occur, Stage three and Stage four together represent deep slow-wave sleep (SWS) with delta waves, Stage five is REM sleep; sleep cycles last between 90-110 minutes each and as the night progresses SWS times reduce and REM times increase.   Sleep includes the operation of synapse synthesis and maintenance through DNA based activity including membrane trafficking, synaptic vesicle recycling, myelin structural protein formation and cholesterol and protein synthesis.  Sleep also controls inflammation (Jan 2019)  Sleep deprivation undermines the thalamus & nucleus accumbens management of pain. 
  is to forget.  The mechanism includes removing synapses, a neuron structure which provides a junction with other neurons.  It generates signal molecules, either excitatory or inhibitory, which are kept in vesicles until the synapse is stimulated when the signal molecules are released across the synaptic cleft from the neuron.  The provisioning of synapses is under genetic control and is part of long term memory formation as identified by Eric Kandel.  Modulation signals (from slow receptors) initiate the synaptic strengthening which occurs in memory.

• Northeastern & Mass. General hospital psychologist Feldman Barrett's fMRI is functional magnetic resonance imaging.  Seiji Ogawa leveraged the coupling of neuronal circuit activity and blood flow through the associated glial cells to build a 3 dimensional picture of brain cell activity.  As haemoglobin gives up its oxygen to support the neural activity it becomes magnetic and acts as a signal detected by the fMRI.  fMRI easily visualizes the state of activity in the living human brain at millimeter resolution, up to several times a second but it cannot track the time course of neural firing so it is augmented with EEG.   studies found superagers' is a older person who remains as mentally agile: in terms of memory and attention; as a twenty year old according to neurologist Marsel Mesulam.  In fMRI analyses superagers are found to retain well developed 'emotional' brain regions: midcingulate cortex, anterior insula; which are major hubs for general communication throughout the brain.  In comparison in other older people these regions have thined and their mental responses are relatively poor.  The superagers maintain the communication networks by regularly performing hard tiring and taxing mental or physical work (Jan 2016).

• Cohen & Andersen's review common reference frames is a coordinate system (set of axis) centered on a particular aspect of the situation that describes the location of an object.  The brain supports many frames of reference including for vision (2009), hearing & movement planning (Jul 2002).  Auditory stimuli are initially coded in a head-centered reference frame.  The motor system codes actions in reference frames that depend on motor effectors.  Eye movements are codes in a reference frame that depends on the difference between current and desired arm position.  It is often necessary to transform the location representation of the sensory stimulus into a representation appropriate for the motor act.  An eye-centered reference frame depends on the location of the eye in the head.  A retinotopic reference frame depends on the retinal location that is activated by a visual stimulus.  Double-saccade tasks show how the location of the second visual target is coded relative to current and desired eye position (eye-centered).

• Working memory is a dominant function of the dorsolateral prefrontal cortex and the areas it connects with.  Prefrontal neurons implement an active memory continuing to fire after the signal is gone for potentially dozens of seconds from the inferior temporal cortex (multi-sensory integration area) and lower level sensory neurons characterized by Hubel & Weisel, while the short-term memory task continues.  If the prefrontal cortex gets distracted the memory is lost from consciousness.  Earl Miller argues the prefrontal cortex implements the rules that decide which working memory neurons will fire (Spring 2017).  Working memory develops from childhood through the late teens, and depends on pyramidal neurons within the PFC.

  loss induced prostate cancer is cancer of the prostate gland.  Genomics detected several common DNA variants associated with increased risk of prostate cancer.  Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8.  The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%.  The high risk variants occur more frequently in African-American men than European or Asians.  African-Americans die from prostate cancer at more than twice the rate of Europeans.  Research in mice may explain a link between obesity and prostate cancer (Jan 2018).  The average diagnosis is at age 66.  Worldwide in 2012 there were 1.1 million cases from which 307,000 died.  A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects.  Various classically defined types of cancer can occur.  The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid.  Epithelial cell differentiation potency makes these significant cancer agents.  Other very rare types of cancer that can start in the prostate are:

• Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.

• Columbia/New York-Presbyterian principal investigator Dr. Gregg Stone reported heart failure is congestive heart failure which occurs when the heart is unable to generate enough blood flow to meet the body's demands.  There are two main types: failure due to left ventricular dysfunction and abnormal diastolic function increasing the stiffness of the left ventricle and decreasing its relaxation.  Heart expansion in CHF distorts the mitral valve which exacerbates the problems.  MitraClip surgery trials found effective in correcting the mitral valve damage (Sep 2018).  Treatments include: digoxin; now has a powerful treatment, Abbott labs's MitraClip, a small device that improves the efficiency of the mitral valve allows blood to flow from the heart's left atrium to the left ventricle.  If it fails the heart will have trouble pumping blood around the body resulting in CHF.   that has been damaged by a heart attack is an AMI. It can induce cardiac arrest.  Blocking the formation of clots with platelet aggregation inhibitors, can help with treating and avoiding AMI.  Risk factors include: taking NSAID pain killers (May 2017).  There is uncertainty about why AMI occur.  Alternative hypotheses include:
  
  • Plaques started to gather in the coronary arteries and grew until no blood flow was possible.  If this is true it makes sense to preventatively treat the buildup with angioplasty. 
    
  • Plaques form anywhere in the body due to atherosclerosis and then break up and get lodged in the coronary artery and start to clot.  If this is true it makes sense to preventatively limit the buildup of plaques with drugs like statins or PCSK9 inhibitors.

• Flaws seen in online treatment (May 2016)
  
• Revenue cycle is either:
  
  • Restrictive cardiomyopathy, a rare disease where scar tissue makes the heart muscle rigid and reduces the efficiency.  Or
    
  • Revenue Cycle Management aligns treatment with reimbursement.  Customer service will be involved.  IT will architect the core billing, decision support and ad-hoc services, constructed by RCM vendors, into systems to support RCM.  The Hospital's central business office will aim to maximize cash recoveries.  As per Deming, mistakes in the RCM pipeline result in rework and lost cash flow and revenue of between 4 - 12%.  The staff must be trained and fully engaged in the design and operation of the pipeline.  The front end processes are best placed to capture all the information needed to make the cycle successful.  The activities include:
  • Scheduling and Appointments - where visits and procedures are booked and demographic and insurance information is collected.  If this information is incorrect it is likely the claims will not forward to third party payers.  When resources and their states are accurately known an optimal set of plans can be constructed to efficiently and effectively flow patients through the system.  But that is difficult to guarantee because of a number of interrelated problems:
  • Scale - as the number of resources increases the ability of a central scheduling system to represent all of them accurately and reliably becomes impossible. 
    
  • Ubiquity - a CAS strategy for ensuring availability is to have an over-abundance of equivalent resource that can be used for schedule allocation.  But often these resource levels are set by local decision makers who all respond at about the same time to imposed funding changes.  The effect is to suddenly and unpredictably undermine the guarantee of over-abundance.  Sometimes the assumption of equivalence also fails as in the desire of a patient to see only a specific surgeon. 
    
  • Changes can ripple through the plans requiring coordination meetings and notifications or guaranteed receipt of status updates. 
    
  • Verification checks for:
    
  • Referral - Is there PCP authorization?  Is the PCP referred service covered by the patient's plan,
    
  • Authorization - obtain Insurance authorization if required, and
    
  • Pre-certification - is there 'need' for inpatient care or other care before admission by the MCO.  Otherwise could introduce problems including not obtaining/verifying the insurance name, number and eligibility, not securing pre-certification and pre-authorization with time limits, not copying the insurance card, not checking for secondary coverage, not detecting expired referral or authorization,
    
  • Pre-registration - provide advice about their financial obligations and what documents to bring to the procedure.  If there is a copay or an outstanding payment to be paid these should be processed,
    
  • Registration - some patients are scheduled outside of the main admitting process (by OP clinic or E.D.) and this must be detected and the scheduling verification and pre-registration process be performed,
    
  • Time of service payments - co pays and self pays,
    
  • Coding - identify diagnosis (ICD 9 -> ICD-10 codes) and treatment (CPT) activities and charges for the episode.  More than 80% of hospital cases are coded in error. 
    
  • Demographics and billing data entry - enter charges and adjust capitated charges,
    
  • Patient statements - submit primary and secondary claims (following HIPAA formats) with or without involvement of a clearinghouse, produce patient statements including time of service, outstanding balance, charged amount with codes, insurance details, forms used (UB 92/04 and HCFA 1500).  A paper based claims filing has a rejection rate of 30%.  Duplicate claim payment rates of 1 - 2% of medical expenses are common.  Duplicate claims detection is often not part of the process.  Payer's goals are in conflict with Provider goals.  
    
  • Collections and payment posting - Post all payments and adjustments and deposit money into the bank,
    
  • Denials and appeals - resubmission and appeal of claims, denial analysis and bad debts and write offs.  To reduce denial rates and appeals the reimbursement contracts payer processes and actual denials must be analyzed and understood.

  targets $6.3 billion for cancer is the out-of-control growth of cells, which have stopped obeying their cooperative schematic planning and signalling infrastructure.  It results from compounded: oncogene, tumor suppressor, DNA caretaker; mutations in the DNA.  In 2010 one third of Americans are likely to die of cancer.  Cell division rates did not predict likelihood of cancer.  Viral infections are associated.  Radiation and carcinogen exposure are associated.  Lifestyle impacts the likelihood of cancer occurring: Drinking alcohol to excess, lack of exercise, Obesity, Smoking, More sun than your evolved melanin protection level; all significantly increase the risk of cancer occurring (Jul 2016). 
  & Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough. 
    
  • Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016). 
    
  • Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
    
  • BACE inhibitors block an enzyme needed to form amyloid. 
    
  • Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons.  The Tau tangles kill nerve cells.  LMTX is a drug treatment targeted at these tangles. 
    
  • The brain becomes inflamed resulting in the killing of many more nerve cells.  The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable.

• Robotic systems perform remote surgery with virtual reality is the full immersion of a human user into a virtually generated world.  Hence the user is not able to interact or think about the real world at the same time.  The use of sensors detecting the user's skin, eyes, ears, and other state and signal generators for touch, hearing, visuals etc. supports the transportation of the brain into an alternate situation where the user can interact.  As long as the sensors are broadly detecting the state of the user's body and the signals are generated at greater than 60 per second it is a truly real experience.  Unfortunately it is hard to fool gravity so these systems can induce motion sickness.  Virtual reality is likely to be significant in medicine in:
  • Training with new tools including surgical instruments. 
    
  • Remote treatment including surgery where the feedback allows the surgeon to operate robotic instruments experiencing the remote OR.

• Carrier screening can provide powerful information for recessively inherited conditions.  It has been used for: Tay-Sachs disease, sickle-cell trait, cystic fibrosis, spinal muscular atrophy; with differing effects.  As more people have complete DNA sequencing carrier screening prior to pregnancy will make increasing sense.  Carrier screening:
  • Is being considered for: 
  • SMA but this requires a complicated and costly genetic test, 
  • Fragile X syndrome may be offered to all females,
    
  • Requires informed consent since it can result in difficult choices. 
    
  • Test reliability depends on the number of potential mutations are involved and how many of these are tested for in the screen.  As of 2010 even cystic fibrosis CFTR gene screening only looks at the 23 most common of the 1000 potential mutations.

• Maternal screening includes a variety of tests during pregnancy to assess the status of the fetus.  There is a degree of uncertainty with the tests facilitating counciling and implying a prospective mother should be given the choice not to have the tests.  Tests include:
  • Ultrasound to check for anatomical abnormalities including congenital heart defects. 
    
  • Maternal blood tests for chromosomal disorders such as Down syndrome and neural tube defects.  The development of liquid biopsys will allow assessment of fetal DNA and RNA in maternal blood. 
    
  for birth defects via maternal blood test: liquid biopsy uses a tiny blood sample used for diagnostic testing.  Often the testing is based on using DNA sequencing to detect DNA in the blood from cancer cells.  By identifying the mutations in a patient's tumor accurate treatments can be selected, and recurrence can be detected.  But aging generates many similar mutations which could lead to false positives in a broad screening test.  Research and development is ongoing (Jun 2016).

  associated with increased: Depression is a debilitating episodic state of extreme sadness, typically beginning in late teens or early twenties. This is accompanied by a lack of energy and emotion, which is facilitated by genetic predisposition - for example genes coding for relatively low serotonin levels, estrogen sensitive CREB-1 gene which increases women's incidence of depression at puberty; and an accumulation of traumatic events.  There is a significant risk of suicide: depression is involved in 50% of the 43,000 suicides in the US, and 15% of people with depression commit suicide.  Depression is the primary cause of disability with about 20 million Americans impacted by depression at any time.  There is evidence of shifts in the sleep/wake cycle in affected individuals (Dec 2015).  The affected person will experience a pathological sense of loss of control, prolonged sadness with feelings of hopelessness, helplessness & worthlessness, irritability, sleep disturbances, loss of appetite, and inability to experience pleasure.  Michael Pollan concludes depression is fear of the past.  It affects 12% of men and 20% of women.  It appears to be associated with androgen deprivation therapy treatment for prostate cancer (Apr 2016).  Chronic stress depletes the nucleus accumbens of dopamine, biasing humans towards depression.  Depression easily leads to following unhealthy pathways: drinking, overeating; which increase the risk of heart disease.   It has been associated with an aging related B12 deficiency (Sep 2016).  During depression, stress mediates inhibition of dopamine signalling.  Both depression and stress activate the adrenal glands' release of cortisol, which will, over the long term, impact the PFC.  There is an association between depression and additional brain regions: Enlarged & more active amygdala, Hippocampal dendrite and spine number reductions & in longer bouts hippocampal volume reductions and memory problems, Dorsal raphe nucleus linked to loneliness, Defective functioning of the hypothalamus undermining appetite and sex drive, Abnormalities of the ACC.  Mayberg notes ACC area 25: serotonin transporters are particularly active in depressed people and lower the serotonin in area 25 impacting the emotion circuit it hubs, inducing bodily sensations that patients can't place or consciously do anything about; and right anterior insula: which normally generates emotions from internal feelings instead feel dead inside; are critical in depression.  Childhood adversity can increase depression risk by linking recollections of uncontrollable situations to overgeneralizations that life will always be terrible and uncontrollable.  Sufferers of mild autism often develop depression.  Treatments include: CBT which works well for cases with below average activity of the right anterior insula (mild and moderate depression), UMHS depression management, deep-brain stimulation of the anterior insula to slow firing of area 25.  Drug treatments are required for cases with above average activity of the right anterior insula.  As of 2010 drug treatments: SSRIs (Prozac), MAO, monoamine reuptake inhibitors; take weeks to facilitate a response & many patients do not respond to the first drug applied, often prolonging the agony.  By 2018, Kandel notes, Ketamine is being tested as a short term treatment, as it acts much faster, reversing the effect of cortisol in stimulating glutamate signalling, and because it reverses the atrophy induced by chronic stress.   Genomic predictions of which treatment will be effective have not been possible because: Not all clinical depressions are the same, a standard definition of drug response is difficult; (Apr 2016), Dementia is a classification of memory impairment, constrained feelings and enfeebled or extinct intellect.  The most common form for people under 60 is FTD.  Dementia has multiple causes including: vascular disease (inducing VCI) including strokes, head trauma, syphilis and mercury poisoning for treating syphilis, alcoholism, B12 deficiency (Sep 2016), privation, Androgen deprivation therapy (Oct 2016), stress, Parkinson's disease, Alzheimer's disease, and prion infections such as CJD and kuru.  The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system.  It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training.  Dementia appears to develop faster in women than men.   including Alzheimer's disease is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause.

• NSAID is a nonsteroidal anti-inflammatory drug, such as ibuprofen.  They inhibit the production of prostaglandins.  They are often used to treat pain and inflammation.  Since prostaglandins are involved in collagen production NSAIDs can undermine healing.  They are also associated with increased risk of heart attacks (May 2017).

  of heart attacks is an AMI. It can induce cardiac arrest.  Blocking the formation of clots with platelet aggregation inhibitors, can help with treating and avoiding AMI.  Risk factors include: taking NSAID pain killers (May 2017).  There is uncertainty about why AMI occur.  Alternative hypotheses include:
  
  • Plaques started to gather in the coronary arteries and grew until no blood flow was possible.  If this is true it makes sense to preventatively treat the buildup with angioplasty. 
    
  • Plaques form anywhere in the body due to atherosclerosis and then break up and get lodged in the coronary artery and start to clot.  If this is true it makes sense to preventatively limit the buildup of plaques with drugs like statins or PCSK9 inhibitors.

• Dec 2015 Cardiac arrest is a sudden halt in the effective blood circulation due to the heart not contracting effectively.  This prevents delivery of oxygen and glucose to the body.  It can be caused by a heart attack.  CHF in contrast, typically has substandard circulation but the heart is still pumping sufficient blood to sustain life.  Cardiac arrest may be reversed with effective treatment.  The treatment regime and effectiveness vary significantly.  They can include:
  • CPR which needs endurance training to sustain for at least 45 minutes of deployment needed for success.  If no pulse is detected after 20 minutes more powerful treatments should be deployed.

• Infectious disease specialists are poorly reimbursed is the payment process for much of US health care.  Reimbursement is the centralizing mechanism in the US Health care network.  It associates reward flows with central planning requirements such as HITECH.  Different payment methods apportion risk differently between the payer and the provider.  The payment methods include:
  • Fee-for-service,
    
  • Per Diem,
    
  • Episode of Care Payment, 
  • Multi-provider bundled EPC,
    
  • Condition-specific capitation,
    
  • Full capitation.  
  , by payers include four types:
  • From the 1930s the insurers Blue Cross and Blue Shield catalyzed health care activity by paying a daily per diem to hospitals for the diagnoses and treatments the hospital's dispensed.  At their inception in 1966 Medicare and Medicaid followed this reimbursement model. 
  • From 1983 Medicare and Medicaid switched to the PPS reimbursement mechanism.  This forced alignment of the supplier, diagnosis, treatment, billing and reimbursement processes.  The health care network is still structurally aligned around PPS.  Under scrutiny of ProPAC and its successor MedPAC,  as well as pressure of the BBA after 1997, the payments per DRG have been steadily reduced until it was below the cost of care, forcing hospitals to seek margin from their other payers.  Medicare outlier payments benefited hospitals that inflated charges and thus became eligible. 
    
  • Employers as they experienced cost shifting from the hospital's increased product charges moved their employees over to managed care based payment. 
  • Private payers pay hospitals directly for their diagnosis and treatment.  Typically this group has little power.  There are default rates for private payers - typically 40% of billed charges that are not covered by a fixed payment or a fee schedule.  For the uninsured poor until 2004 they obtained little discount on the hospital's chargemaster list price, because insurers and CMS required to be charged the lowest value offered to any patients.  Medicare has now relaxed this constraint.

  • Individual human decision making includes conscious and unconscious aspects.  Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too.  Emotions are important in providing a balanced judgement.  The adaptive unconscious interprets percepts quickly supporting 'fast' decision making.  Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy.  The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex.  The BLA supports rejecting unacceptable offers.  Moral decisions are influenced by a moral decision switch.  Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference.  Word framing demonstrates the limitations of our fast intuitive decision making processes.  And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices.  Prior to the development of the PFC, the ventral striatum supports adolescent decision making.  Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex.  This allows them to link perceptions with a provisional action plan.  Association neurons can track probabilities connected to a choice.  As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive.  Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.

  treatment
  
• Sep 2015 Antibiotics associated with diabetes is the leading cause of blindness, limb amputations and kidney failure.  It is a risk factor for Alzheimer's disease.  Insulin and glucose levels are regulated by the pancreas, liver, muscle, brain and fat.  Diabetes occurs when the insulin level is insufficient to regulate the glucose in the system.  As we age our muscles become less sensitive to insulin and the pancreas responds by increasing the amount generated.  Increased fat levels in obesity demand more insulin overloading the pancreas.  Persistent high glucose levels are also toxic to the pancreas beta cells.  High glucocorticoid levels have been associated with type 2 diabetes.  There are genetic risk factors since siblings of someone with the disease have three times the baseline risk (about 50% of the risk of getting type 2 diabetes is genetic).  The inheritance is polygenic.  More than 20 genes have been identified as risk factors, but that is too few to account for the 50% weighting so many more will be identified.  Of those identified so far many are associated with the beta cells.  The one with the strongest relative risk is TCF7L2.  The disease can be effectively controlled through a diligent application of treatments and regular checkups.  Doctors are monitored for how under control their patients' diabetes is (Sep 2015).  Treatments include:
  • Metformin - does not change the course of pre-diabetes - if you stop taking it, it is as if it hasn't been taken. 
    
  • Diet
  • Exercise
  
  
• May 2015 Clostridium difficile usually competes with other bacteria in the human gut microbiome.  But antibiotic treatments provide it with an advantage where it becomes the predominant gut bacteria causing diarrhea, abdominal pain, and toxic megacolon.  Repeated treatments select for infections that are progressively more difficult to treat.  C. difficile infections kill more than 25,000 people a year in the US.  Fecal transplants, especially enabled by stool-banking, reintroduce competitive bacteria that limit the success of C. difficile and cure patients with previously recurrent infections.  But the F.D.A. has not approved such transplants as a treatment and the procedure is not covered by insurance.

  and prostate is cancer of the prostate gland.  Genomics detected several common DNA variants associated with increased risk of prostate cancer.  Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8.  The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%.  The high risk variants occur more frequently in African-American men than European or Asians.  African-Americans die from prostate cancer at more than twice the rate of Europeans.  Research in mice may explain a link between obesity and prostate cancer (Jan 2018).  The average diagnosis is at age 66.  Worldwide in 2012 there were 1.1 million cases from which 307,000 died.  A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects.  Various classically defined types of cancer can occur.  The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid.  Epithelial cell differentiation potency makes these significant cancer agents.  Other very rare types of cancer that can start in the prostate are:

  remotely inhibiting the immune system has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome.  It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier.  It culls species within the microbiome that are expanding beyond requirements.  It destroys invaders who make it into the internal transport networks.  As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap.  The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding.  The immune system consists of two main parts the older non-adaptive part and the newer adaptive part.  The adaptive part achieves this property by being schematically specified by DNA which is highly variable.  By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen).  When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen.  Once the antibody becomes bound to the antigen the immune system cells can destroy the invader.

  message, where the signal, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance.  In eukaryotic cells signalling is used extensively.  A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form.  Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell.  Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state.  Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals.  Cell signalling is reviewed by Helmreich.  Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors.  In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation.  To be credible signals must be hard to fake.  To be effective they must be easily detected by the target recipient.  To be efficient they are low cost to produce and destroy.

• Cuban immunotherapy vaccine are a core strategy of public health and have significantly extended global wellbeing over 200 years.  Smallpox & polio were virtually eradicated.  Recent successes include: HPV vaccine: Gardasil.  They induce active acquired immunity to a particular disease.  But the development and deployment of vaccines is complex:
  • The business model for vaccine development has been failing (Aug 2015): 
    
  • No Zika vaccine was available as the epidemic grew (Mar 2016).  No vaccine for: CMV;
    
  • Major foundations: Michael J. Fox, Gates, Wellcome; are working to improve the situation including sponsorship of the GAVI alliance.  A geographic cluster is forming in Seattle including PATH (Apr 2016). 
    
  • Commercial developers include: Affiris, Cell Genesis, Chiron, CSL, Sanofi, Valeant;
    
  • Vaccine deployment traditionally benefited from centrally managed vertical health programs.  But political issues are now constraining success with less than 95-99% coverage required for herd immunity (Aug 2015, Sep 2015, Nov 2015, Nov 2016, Jul 2018).  
  • Where clinics have been driven into local neighborhoods health improves (Apr 2016).  
  • Retail clinics (Mar 2016): CVS Minute Clinics focus on vaccination. 
    
  • NNT is a useful metric for vaccine benefit.  Influenza vaccine has an NNT of between 37 and 77, is cheap and causes little harm, so it is very beneficial. 
    
  • Key vaccines include: BCG, C. difficile (May 2015), Cholera (El Tor), Cervical Cancer (Gardasil HPV Jun 2018, Oct 2018), Dengvaxia (Mexico Dec 2015), Gvax, Influenza, Malaria vaccine, Provenge, Typbar-TCV (XDR typhoid Pakistan Apr 2018);
  • Regulation involves: FDA (CBER), with CMS monitoring (star ratings, PACE (Aug 2016), Report cards (Sep 2015)) & CDC promoting vaccines: as a sepsis measure, To control C. difficile (May 2015);  
  • Coding : CVX, MVX;
    
  • Research on vaccines includes: 
  • NIH: AIDS vaccines (AVRC), Focus on using genetic analysis to improve vaccine response.

  • Non-small-cell carcinomas are of three sub-types:
  • Adenocarcinomas (40% of lung cancers) are typically peripherally situated and mostly induced by smoking.
    
  • Squamous-cell carcinomas (30% of lung cancers) arise in the large bronchi an are highly correlated with smoking. 
    
  • Large-cell carcinomas (5 to 10% of lung cancers).
    
  • Small-cell carcinomas.

• NK are natural killer cells:
  
  • Are cell killing lymphocytes that participate in the innate and adaptive immune system responses.  
  • Are unusual in recognising stressed cells without signalling from antibodies or MHC.  They consequently respond relatively rapidly.  And they kill cells that T-lymphocytes will not. 
    
  • Attack viral-infected cells and tumor cells.  
  • Express cell surface proteins CD16 & CD56.

• Electric field found to be quick acting replacement for viral delivery platforms, allowing CRISPR is clustered replicating interspersed silent palindromic repeats; a technique for exact targeting, cutting and editing of DNA based on leveraging bacterial enzymatic defenses against viruses generalized to any DNA sequence in a prokaryotic or eukaryotic cell.  It was identified during studies of a bacterial adaptive immune system.  In that system bacterial proteins grab parts of a virus that has infected them and record it within the palindromic structures that mark an array of inserted viral DNA used as a log persisted over generations.  If a new infection occurs the viral DNA is compared with the sequences and if a match exists the CAS proteins break up the viral DNA initiating its destruction.  This bacterial system was then updated and repurposed by the researchers to support targeted genetic engineering.  As explained by Dr. Doudna, the CRISPR proteins and the 20 nucleotide RNA template migrate into the nucleus where they rapidly target DNA which complements the RNA template and the Cas9 enzyme performs the edits.  Being a bacterial system CRISPR Cas9 does not target eukaryotic heterochromatic DNA well.  It is not fully understood how they find the target sequence so quickly.  It has been shown that Cas9 will bind to sites with a 5-8 base match but then it releases rapidly without cutting.  To cut, Cas9 has to reconfigure, which does not occur in the mismatch situations.   introduction to T-cells are a type of leukocyte.  They appear mainly in the lymphatic network.  Their are various types:
  • B cells which make antibodies that bind to pathogens, and activate the complement system.  When malignant these cells can produce multiple myeloma.

  for sickle-cell anemia is a recessive single gene disease where the sufferer's hemoglobin causes the red blood cells to distort.  It is a side effect of the evolved protection from malaria provided by sickle cell trait.  Potential treatments include gene therapy and drugs that block the sickling of red blood cells.  Carrier screening was undermined by there being no effective prenatal test limiting the benefit of the information and because the white doctors were not trusted by their black patients.  In the future iPS cells could have the problem mutations replaced with ex vivo gene therapy. 
  in trials: Boston Children's; resulting in patients with no symptoms, mid trail.  Red blood stem cells is a biological cell which is partly or wholly undifferentiated.  A totipotent cell can generate a complete embryo and placenta.  Embryos include pluripotent cells which can generate any tissue in the body.  Adult humans' cells have turned off this ability but still include multipotent stem cells that differentiate into multiple cell types.   Typically a cell's local environment will have the signals required for it to obtain context and differentiate appropriately.  This will include both the external environment and the internal state of the cell which has replicated from a parent and obtained its epi-genetic state.   So introduction of undifferentiated stem cells into an injured area is not likely to have either aspect of the environment suitable.  Consequently development is aiming to encourage differentiation to progenitor cells for the damaged region.  This requires delivering the cells to the appropriate part of the body.  To avoid rejection by the immune system techniques aim to use cell lines developed from the patient's cells.  The techniques to generate these cell lines include: SCNT, iPS.  Possible mechanisms of stem cell therapy are: Generation of new differentiated cells, Stimulation of growth of new blood vessels to repopulate damaged regions, Secretion of growth factors, Treatment of diabetes (1 and 2) with addition of pancreatic cells, Assistance of other mechanisms; are removed from the bone marrow, the sickle-cell gene mutation is removed from the DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains.  DNA naturally forms into helical pairs with the side chains stacked in the center of the helix.  It is a natural form of schematic string.  The purines and pyrimidines couple so that AT and GC pairs make up the stackable items.  A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence.  Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema.  To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. 
  and the stem-cells are flowed back into the body, where they must reenter the bone marrow for the therapy to work.  Genetic update can use newly discovered large viral vector.   An alternative to gene therapy uses a gene edit using CRISPR is clustered replicating interspersed silent palindromic repeats; a technique for exact targeting, cutting and editing of DNA based on leveraging bacterial enzymatic defenses against viruses generalized to any DNA sequence in a prokaryotic or eukaryotic cell.  It was identified during studies of a bacterial adaptive immune system.  In that system bacterial proteins grab parts of a virus that has infected them and record it within the palindromic structures that mark an array of inserted viral DNA used as a log persisted over generations.  If a new infection occurs the viral DNA is compared with the sequences and if a match exists the CAS proteins break up the viral DNA initiating its destruction.  This bacterial system was then updated and repurposed by the researchers to support targeted genetic engineering.  As explained by Dr. Doudna, the CRISPR proteins and the 20 nucleotide RNA template migrate into the nucleus where they rapidly target DNA which complements the RNA template and the Cas9 enzyme performs the edits.  Being a bacterial system CRISPR Cas9 does not target eukaryotic heterochromatic DNA well.  It is not fully understood how they find the target sequence so quickly.  It has been shown that Cas9 will bind to sites with a 5-8 base match but then it releases rapidly without cutting.  To cut, Cas9 has to reconfigure, which does not occur in the mismatch situations.  .  Another treatment strategy blocks the genetic transition from fetal to adult hemoglobin: fetal does not sickle.  NIH is the National Institute of Health, Bethesda Maryland.  It is the primary federal agency for the support and conduct of biomedical and behavioral research.  It is also one of the four US special containment units of the CDC.   is launching a funding program 'Cure Sickle-Cell' (Jan 2019)

• Active surveillance is an approach to early-stage prostate cancer which replaces treatment, such as surgery or radiation, with monitoring to ensure the cancers aren't growing rapidly.  It started to be used in about 2000 and so will take time to build a predictive history of the success of the regimen (10 year longitudinal study results Sep 2016).  Active surveillance treatements include: Oncotype DX, PSA, STHLM3; helping in treatment for prostate cancer is cancer of the prostate gland.  Genomics detected several common DNA variants associated with increased risk of prostate cancer.  Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8.  The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%.  The high risk variants occur more frequently in African-American men than European or Asians.  African-Americans die from prostate cancer at more than twice the rate of Europeans.  Research in mice may explain a link between obesity and prostate cancer (Jan 2018).  The average diagnosis is at age 66.  Worldwide in 2012 there were 1.1 million cases from which 307,000 died.  A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects.  Various classically defined types of cancer can occur.  The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid.  Epithelial cell differentiation potency makes these significant cancer agents.  Other very rare types of cancer that can start in the prostate are:
  • Sarcomas

• Dementia
  
• Plaque helps predict Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.

  which garbage collect: tau, amyloid; and support immune has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome.  It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier.  It culls species within the microbiome that are expanding beyond requirements.  It destroys invaders who make it into the internal transport networks.  As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap.  The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding.  The immune system consists of two main parts the older non-adaptive part and the newer adaptive part.  The adaptive part achieves this property by being schematically specified by DNA which is highly variable.  By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen).  When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen.  Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. 
  regulation.  Mice memory in the brain includes functionally different types: Declarative, or explicit, (episodic and semantic), Implicit, Procedural, Spatial, Temporal, Verbal; Hebb suggested that glutamate receptive neurons learn by (NMDA channel based) synaptic strengthening: short term memory.  This was shown to happen for explicit memory formation in the hippocampus.  This strengthening is sustained by subsequent LTP.  The non-real-time learning and planning processes operate through consciousness using the working memory structures, and then via sleep, the salient ones are consolidated while the rest are destroyed and garbage collected.   and cognition is the ability to orchestrate thought and action in accordance with internal goals according to Princeton's Jonathan Cohen. 
  improved, with auditory cortex is part of the temporal lobe that processes auditory information.  It is present in both brain hemispheres.  Auditory sensations only reach consciousness once signalled by the auditory cortex.  Final sound processing is performed by the parietal and frontal lobes in humans. 
  and hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory.  It includes the dentate gyrus.  Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation.  The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle.  Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information.  During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation.  It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories.  The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point.  Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits.  It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky.  Prolonged stress makes the hippocampus atrophy.  He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different.  Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease.  It directly signals area 25. 
  protected by sounds, and sounds with light additionally helping maintain the PFC is prefrontal cortex which is:
  • The front part of the frontal lobe of the cerebral cortex.  It evolved most recently.  During adolescence when the PFC is still deploying, older brain agents provide equivalent strategies: ventral striatum.  The PFC has been implicated in planning, working memory: dorsolateral; decision making: Orbitofrontal cortex; and social behavior.  It regulates feelings.  Different PFC circuits track internal reward driven strategies and externally signalled advice.  The PFC chooses between conflicting options, letting go or restraint, especially between cognition and emotions.  It imposes an overarching strategy for managing working memory.  It is essential for thinking about multiple items with different labels.  It includes neurons that are interested in particular sub-categories: Dog, Cat.  Once it has made a decision it signals the rest of the frontal lobe just behind it.  Glucocorticoids decrease excitability of the PFC.

• Research autopsies of Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough. 
    
  • Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016). 
    
  • Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
    
  • BACE inhibitors block an enzyme needed to form amyloid. 
    
  • Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons.  The Tau tangles kill nerve cells.  LMTX is a drug treatment targeted at these tangles. 
    
  • The brain becomes inflamed resulting in the killing of many more nerve cells.  The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable. 
    
  victims often indicate multiple problems that induce dementia is a classification of memory impairment, constrained feelings and enfeebled or extinct intellect.  The most common form for people under 60 is FTD.  Dementia has multiple causes including: vascular disease (inducing VCI) including strokes, head trauma, syphilis and mercury poisoning for treating syphilis, alcoholism, B12 deficiency (Sep 2016), privation, Androgen deprivation therapy (Oct 2016), stress, Parkinson's disease, Alzheimer's disease, and prion infections such as CJD and kuru.  The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system.  It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training.  Dementia appears to develop faster in women than men.  : silent-strokes is when brain cells are deprived of oxygen and begin to die.  750,000 patients a year suffer strokes in the US.  85% of those strokes are caused by clots.  There are two structural types: Ischemic and hemorrhagic.  Thrombectomy has been found to be a highly effective treatment for some stroke situations (Jan 2018). 
  , Lewy bodies are protein clumps that are a pathological mark of Parkinson's disease and Lewy body dementia.  A major component of the clumps is alpha-synuclein.  , amyloid, hippocampal sclerosis, TDP-43; and the disease is typically associated with reduced blood flow to the cerebrum is a developmental classification of brain areas formed from the embryonic prosencephalon.  These areas include the cerebral cortex, hippocampus, olfactory bulb and the basal ganglia. 
  explains Harvard's Dr. Hofman & Bristol's Dr. Love, age is the most significant risk factor asserts Washington University in St. Louis' Dr. Morris.  A decline of 15% in new cases over 25 years matches: reduced smoking, use of statins are serum cholesterol lowering drugs established as safe and effective at reducing the risk of heart-attacks, hemorrhagic & Ischemic strokes and deaths from atherosclerotic heart disease.  They also reduce inflammation that can induce blood clots.  They appear to stabilize plaque.  About 5% of people, most with a specific allele of SLCO1B1, have muscle aches, and in some blood sugar increases.  Statins inhibit HMG-CoA reductase which produces cholesterol in the liver.  , and hypertension is high blood pressure.  It is directly associated with death rate due to pressure induced damage to the left ventricle and in general to cardiovascular diseases.  Treated with antihypertensives: Diuretics, Calcium channel blockers, Angiotensin receptor blockers or Beta blockers.   management (Apr 2019)

• Alzheimer's develops faster and more often with obesity is an addictive disorder where the brain is induced to require more eating, often because of limits to the number of fat cells available to report satiation (Jul 2016).  Brain images of drug-addicted people and obese people have found similar changes in the brain.  Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors.  Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so.  Obesity is associated with: metabolic syndrome including inflammation, cancer (Aug 2016), high cholesterol, hypertension, type-2-diabetes, asthma and heart disease.  It is suspected that this is contributing to the increase in maternal deaths in the US (Sep 2016).  Obesity is a complex condition best viewed as representing many different diseases, which is affected by the: Amount of brown adipose tissue (Oct 2016), Asprosin signalling by white adipose tissue (Nov 2016), Genetic alleles including 25 which guarantee an obese outcome, side effects of some pharmaceuticals for: Psychiatric disorders, Diabetes, Seizure, Hypertension, Auto-immunity; Acute diseases: Hypothyroidism, Cushing's syndrome, Hypothalamus disorders; State of the gut microbiome.  Infections, but not antibiotics, appear associated with childhood obesity (Nov 2016).

  therapy for prostate cancer is cancer of the prostate gland.  Genomics detected several common DNA variants associated with increased risk of prostate cancer.  Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8.  The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%.  The high risk variants occur more frequently in African-American men than European or Asians.  African-Americans die from prostate cancer at more than twice the rate of Europeans.  Research in mice may explain a link between obesity and prostate cancer (Jan 2018).  The average diagnosis is at age 66.  Worldwide in 2012 there were 1.1 million cases from which 307,000 died.  A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects.  Various classically defined types of cancer can occur.  The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid.  Epithelial cell differentiation potency makes these significant cancer agents.  Other very rare types of cancer that can start in the prostate are:
  • Sarcomas
  • Small cell carcinomas
  • Neuroendocrine tumors

  treatment stents is a small wire cage that can be inserted into an artery to prop it open.  They were introduced as an alternative to bypass surgery in the 1990s.  Stents are expensive.  Medicare payments vary depending on what kind of stent is used and how many, but are generally in the range $10,000 to $17,000 in 2015.   Double blind trials show that stents have no effect on chest pain relief (Nov 2017)
  found to provide no relief for chest pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems.  But feeling pain is supported by older biological functions that support homeostasis.  These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems.  Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'.  Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers.  A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex.  The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks.  Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so.  Fear of pain is a significant contributor to female anxiety.  Pain is the main reason people visit the ED in the US.  Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation.

  , type 2 diabetes is the leading cause of blindness, limb amputations and kidney failure.  It is a risk factor for Alzheimer's disease.  Insulin and glucose levels are regulated by the pancreas, liver, muscle, brain and fat.  Diabetes occurs when the insulin level is insufficient to regulate the glucose in the system.  As we age our muscles become less sensitive to insulin and the pancreas responds by increasing the amount generated.  Increased fat levels in obesity demand more insulin overloading the pancreas.  Persistent high glucose levels are also toxic to the pancreas beta cells.  High glucocorticoid levels have been associated with type 2 diabetes.  There are genetic risk factors since siblings of someone with the disease have three times the baseline risk (about 50% of the risk of getting type 2 diabetes is genetic).  The inheritance is polygenic.  More than 20 genes have been identified as risk factors, but that is too few to account for the 50% weighting so many more will be identified.  Of those identified so far many are associated with the beta cells.  The one with the strongest relative risk is TCF7L2.  The disease can be effectively controlled through a diligent application of treatments and regular checkups.  Doctors are monitored for how under control their patients' diabetes is (Sep 2015).  Treatments include:
  • Metformin - does not change the course of pre-diabetes - if you stop taking it, it is as if it hasn't been taken.

• Crispr is clustered replicating interspersed silent palindromic repeats; a technique for exact targeting, cutting and editing of DNA based on leveraging bacterial enzymatic defenses against viruses generalized to any DNA sequence in a prokaryotic or eukaryotic cell.  It was identified during studies of a bacterial adaptive immune system.  In that system bacterial proteins grab parts of a virus that has infected them and record it within the palindromic structures that mark an array of inserted viral DNA used as a log persisted over generations.  If a new infection occurs the viral DNA is compared with the sequences and if a match exists the CAS proteins break up the viral DNA initiating its destruction.  This bacterial system was then updated and repurposed by the researchers to support targeted genetic engineering.  As explained by Dr. Doudna, the CRISPR proteins and the 20 nucleotide RNA template migrate into the nucleus where they rapidly target DNA which complements the RNA template and the Cas9 enzyme performs the edits.  Being a bacterial system CRISPR Cas9 does not target eukaryotic heterochromatic DNA well.  It is not fully understood how they find the target sequence so quickly.  It has been shown that Cas9 will bind to sites with a 5-8 base match but then it releases rapidly without cutting.  To cut, Cas9 has to reconfigure, which does not occur in the mismatch situations.   and Talen is transcription activator-like effector nuclease.  These are restriction enzymes that function as a dimer with unique DNA binding domains.

  with Geisinger - stored in EHR refers to electronic health records which are a synonym of EMR.  EHR analysis suggests strengths and weaknesses:
  • The EHR provides an integrated record of the health systems notes on a patient including: Diagnosis and Treatment plans and protocols followed, Prescribed drugs with doses, Adverse drug reactions;
  • The EHR does not necessarily reflect the patient's situation accurately. 
    
  • The EHR often acts as a catch-all.  There is often little time for a doctor, newly attending the patient, to review and validate the historic details. 
    
  • The meaningful use requirements of HITECH and Medicare/Medicaid specify compliance of an EHR system or EHR module for specific environments such as an ambulatory or hospital in-patient setting. 
    
  • As of 2016 interfacing with the EHR is cumbersome and undermines face-to-face time between doctor and patient.  Doctors are allocated 12 minutes to interact with a patient of which less than five minutes was used for recording hand written notes.  With the EHR 12 minutes may be required to update the record!

• Impacts of hospital stays on the elderly: disrupted sleep facilitates salient memory formation and removal of non-salient memories.  The five different stages of the nightly sleep cycles support different aspects of memory formation.  The sleep stages follow Pre-sleep and include: Stage one characterized by light sleep and lasting 10 minutes, Stage two where theta waves and sleep spindles occur, Stage three and Stage four together represent deep slow-wave sleep (SWS) with delta waves, Stage five is REM sleep; sleep cycles last between 90-110 minutes each and as the night progresses SWS times reduce and REM times increase.   Sleep includes the operation of synapse synthesis and maintenance through DNA based activity including membrane trafficking, synaptic vesicle recycling, myelin structural protein formation and cholesterol and protein synthesis.  Sleep also controls inflammation (Jan 2019)  Sleep deprivation undermines the thalamus & nucleus accumbens management of pain. 
  , unappetizing meal impacts, reduced muscle mass, poor balance, additional medicine complications, delirium, pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems.  But feeling pain is supported by older biological functions that support homeostasis.  These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems.  Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'.  Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers.  A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex.  The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks.  Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so.  Fear of pain is a significant contributor to female anxiety.  Pain is the main reason people visit the ED in the US.  Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation.

D. profitability has been helped by hospitals contracting with 3rd party companies who are able to improve margins through surprise billing.  The standalone E.D. competes with the positioning and brand power of lower cost urgent care clinics.  Commercial nature of care requires walk-ins to register to gain access to care.  With the focus on treatment of pain, E.D.s are a major distributor of opioids (5% of opioid prescriptions) and a major starting point of addiction in patients but are cutting back (Jun 2016).

• Alzheimer's is a dementia which correlates with deposition of amyloid plaques in the neurons.  As of 2015 there are 5 million Alzheimer's patients in the USA.  It was originally defined as starting in middle age which is rare, so it was a rare dementia.  But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI).  Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged.  The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease.  Grid cell destruction results in a sense of being lost.  The default mode network is disrupted.  Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes.  There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016).  The Alzheimer's pathway follows:
  • Plaques form.  These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes.  APP deployed in the cell membrane is cut into three parts.  The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough. 
    
  • Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016). 
    
  • Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
    
  • BACE inhibitors block an enzyme needed to form amyloid. 
    
  • Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons.  The Tau tangles kill nerve cells.  LMTX is a drug treatment targeted at these tangles. 
    
  • The brain becomes inflamed resulting in the killing of many more nerve cells.  The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable.

• Mount Sinai Icahn SOM's Dr. Joel Dudley's precision medicine is the integration of molecular research: genomics, proteomics, transcriptomics, metabolomics, cell signalling; and clinical data through a taxonomy based on CAS modeling overlaid on an information commons.  It aims to support treatment of disease and remove the organ and symptom based methodological flaws in the ICD.  Supporters of the D.S.M. note the aggressive shift to precision medicine at the NIMH under Dr. Insel, constrained useful clinical research (Nov 2015). 
  (Big Data encompasses the IT systems and processes necessary to do population based data collection, management and analysis.  The very low cost, robust, data storage organized by infrastructure: HADOOP; allows digital data to be stored en mass.  Data scientists then apply assumptions about the world to the data, analogous to evolved mechanisms in vision, in the form of algorithms: Precision medicine, Protein folding modeling (Feb 2019) assumes coevolutionary methods can be applied to identify contact points in a protein's tertiary structure.  Rather than depending on averages, analysis at Verisk drills down to specifics and then highlights modeling problems by identifying the underlying CAS.  For the analysis to be useful it requires a hierarchy of supporting BI infrastructure:
  • Analytics utilization and integration delivered via SaaS and the Cloud to cope with the silos and data intensive nature. 
    
  • Analytics tools (BI) for PHM will be hard to develop.  
  • Complex data models must include clinical aspects of the patient specific data, including disease state population wide.  
  • A key aspect is providing clear signals about the nature of the data using data visualization. 
    
  • Data communication with the ability to exchange and transact.  HIEs and EMPI alliance approaches are all struggling to provide effective exchange. 
    
  • Data labeling and secure access and retreival.  While HIPAA was initially drafted as a secure MPI the index was removed from the legislation leaving the US without such a tool.  Silos imply that the security architecture will need to be robust. 
    
  • Raw data scrubbing, restructuring and standardization.  Even financial data is having to be restandarized shifting from ICD-9 to -10.  The intent is to transform the unstructured data via OCR and NLP to structured records to support the analytics process. 
    
  • Raw data warehousing is distributed across silos including PCP, Hospital system and network, cloud and SaaS for process, clinical and financial data. 
    
  • Data collection from the patient's proximate environment as well as provider CPOE, EHRs, workflow and process infrastructure.  The integration of the EHR into a big data collection tool is key.
