Imagine a physician sitting down with his laptop and
a morning cup of coffee. On a website that he uses to
help manage his practice, an alert pops up. It tells
him that a series of studies have demonstrated a
connection between multiple rare mutations found
in 10 percent of people and the likelihood that they
might convert to type 2 diabetes. Nearly all of his
patients have had their entire genome sequenced
and entered into their electronic medical record – a
process that takes only a week, costs a few hundred
dollars, and is reimbursed by insurance companies
because of the many benefits it provides to lifelong
health management. He conducts a quick search of
his 2,000 patient database and finds about 80 who
are at risk. To half of those patients, he sends a strong
reminder and advice on diet and lifestyle choices
they can take to avoid the disease. To the other half,
whose medical records reveal pre‐diabetic
symptoms, he sets up appointments to consider
more proactive treatment with drugs that can
prevent the onset of disease.

Keynote at On the Move conference, October 2011, Greece.
Abstract:
Traditionally, we had to artificially simplify the complexity and richness of the real world to constrained computer models and languages for more efficient computation. Today, devices, sensors, human-in-the-loop participation and social interactions enable something more than a “human instructs machine” paradigm. Web as a system for information sharing is being replaced by pervasive computing with mobile, social, sensor and devices dominated interactions. Correspondingly, computing is moving from targeted tasks focused on improving efficiency and productivity to a vastly richer context that support events and situational awareness, and enrich human experiences encompassing recognition of rich sets of relationships, events and situational awareness with spatio-temporal-thematic elements, and socio-cultural-behavioral facets. Such progress positions us for what I call an emerging era of “computing for human experience” (CHE). Four of the key enablers of CHE are: (a) bridging the physical/digital (cyber) divide, (b) elevating levels of abstractions and utilizing vast background knowledge to enable integration of machine and human perception, (c) convert raw data and observations, ranging from sensors to social media, into understanding of events and situations that are meaningful to humans, and (d) doing all of the above at massive scale covering the Web and pervasive computing supported humanity. Semantic Web (conceptual models/ontologies and background knowledge, annotations, and reasoning) techniques and technologies play a central role in important tasks such as building context, integrating online and offline interactions, and help enhance human experience in their natural environment.
In this talk I will discuss early enablers of CHE including semantics-empowered social networking and sensor Web, and computation of higher level abstractions from raw and phenomenological data. An article in IEEE Internet Computing provides background information: http://bit.ly/HumanExperience

Bibliographie sur la couverture sanitaire universelle - AfHEAHFG Project
On October 28, Health Systems Global (HSG)’s Translating Evidence into Action Working Group hosted a webinar on a regional initiative to empower public and private leaders in Francophone Africa with evidence and research related to universal health coverage (UHC). In response to calls for UHC reforms in the region, the African Health Economics and Policy Association (AfHEA) has trained over 45 policymakers and other stakeholders from 16 countries across Francophone Africa to address their urgent need for relevant evidence and knowledge to advance their country’s progress towards UHC. Training participants were self- or employer- financed, and came from Ministries of Health, quasi-governmental agencies (social security agencies, health insurance), or were young African researchers, analysts, and activists in civil society.
The webinar focused on how AfHEA made the wealth of evidence on financing and structuring UHC in English, accessible in French (What did policy makers need to make UHC policy and how did AfHEA get it to them successfully?) and how the training participants continue to support each other in using evidence to inform policy (Where do policymakers go for evidence or technical support and what is most useful to them?). The hour-long webinar—held in French with a separate line for simultaneous English translation—saw over 50 participants and featured four speakers.
Speakers:
Pascal Ndiaye, Health Finance and Policy Specialist, AfHEA (Moderator)
Miloud Kaddar, Senior Health Economist, World Health Organization (Panelist)
Marie Nome Essoh Lattroh, Technical Adviser, Ministry of Economy and Finance, Senegal (Panelist)
Hugues B.M. Tchibozo, Deputy Director General, National Health Insurance Agency, Ministry of Health, Benin (Panelist)
The panel included training participants (Ms. Lattroh and Mr. Tchibozo), an instructor (Mr. Kaddar), and an organizer (Mr. Ndiaye). The diverse experiences provided for a rich panel and discussion.
Major takeaways from the webinar:
The increased global focus on UHC represents an opportunity to advance policies and strategies for extending health care access to vulnerable populations across Africa.
UHC should be a medium to long term goal requiring a health systems approach and sustained engagement by all actors and stakeholders.
There is no single source of funding for UHC.
Resolving shortages and unequal distribution of the health workforce in Africa is essential for achieving UHC.
While the term “universal” signals that the entire population will be “covered,” an unanswered question is: covered with what? What benefits or interventions represent “coverage”?
The importance and diversity of the informal sector requires special attention. Policies must be based on context-specific evidence of what works.

Genomics, Personalized Medicine and Electronic Medical RecordsLyle Berkowitz, MD
We are now unlocking the secrets of health at a molecular level – which includes not only why some people get diseases, but also how to prevent or cure them. However, as Osler points out, knowing this information is only valuable in the context of making it available for the right patient at the right time.
This presentation provides a basic introduction to genomic or personalized medicine, and discusses how this information can and should be integrated into our electronic medical record systems.

Non-invasive Diagnostic Tools: Cardiometabolic Risk Assessment and Predictionasclepiuspdfs
Cardiometabolic risks (CMRs) have rapidly increased to epidemic proportions worldwide in the past three decades. Cardiovascular disease (CVD) remains the number one killer. No country has reduced, reversed, or prevented the increase in the incidence or prevalence of chronic metabolic diseases. Framingham Heart Study group described the modifiable risk factors that promote the development of CVD. They also developed risk calculators, for the prediction of acute vascular events such as heart attacks and stroke. The risk predictor algorithms were fine-tuned, as and when additional risk factors were discovered. However, at the time of this writing, there is no such calculator for assessment, stratification, and management of CMRs. On the other hand, numbers of non-invasive diagnostic devices have been developed for continuous monitoring of blood pressure and glucose profiles.

Prediction of Heart Disease in Diabetic patients using Naive Bayes Classifica...Editor IJCATR
The objective of our paper is to predict the risk of heart disease in diabetic patients. In this research paper we are applying Naive Bayes data mining classification technique which is a probabilistic classifier based on Bayes theorem with strong (naive) independence assumptions between the features. Data mining techniques have been widely used in health care systems for prediction of various diseases with accuracy. Health care industry contains large amount of data and hidden information. Effective decisions are made with this hidden information by applying data mining techniques. These techniques are used to discover hidden patterns and relationships from the datasets. The major challenge facing the healthcare industry is the provision for quality services at affordable costs. A quality service implies diagnosing patients correctly and treating them effectively. In this proposed system certain attributes are consider in diabetic patients to predict the risk of heart disease
Effect of Urea on the Production of Chitinase by Trichoderma Virideijtsrd
Trichoderma spp. is proved to be an efficient bio control agent. It is one of the most frequently studied genera in relation to biological control of plant diseases. The bio control activity of Trichoderma spp depends on the production of large number of hydrolytic enzymes. Trichoderma spp. produces variety of antimicrobial substances or biologically active substances those are inhibitory to plant pathogens. Trichoderma is one of the groups of beneficial fungi, that have been shown to act, and are commercially applied as biocontrol agents against fungal pathogens. Trichoderma Biocontrol agents can even exert positive effects on plants with an increase in plant growth and also in the stimulation of plant defense mechanism. Urea did not show any negative impact on the growth of Trichoderma viride. Trichoderma viride cannot be applied to crops along with fungicides or insecticides. While applying chemical fertilizers, care maybe taken by avoiding the place and time of application of both.

Diabetes: The Facts
The number of Americans with diabetes has tripled over the last 30 years – and experts see no end to the trend. The Centers for Disease Control and Prevention predicts that the number of people with diabetes will continue to rise, until 1 in 3 people could have the disease by 2050.
Getting more physical activity and sleep, eating a healthier diet, and managing stress are all lifestyle changes that can cut the risk for diabetes – and obesity.
This Infographic shows the Causes, Number of Affected People, the Cost related to Diabetes and ways of Prevention.
Diabetes is a significant cause of mortality and morbidity in different continents of the world. Many diabetes victims are found in developing countries like Sub-Saharan Africa. However, some developed nations like United States and Europe record significant records on diabetes prevalence. Studies project a dramatic increase of the infection spread in the world. Also, it provides visible results on the effects of the infection among the victims and the society at large. Studies of type 2 diabetes prevalence indicate minimal rates in rural population and moderate results in the developed regions of the same country. Such results create an alarm to the unaffected regions. The frequent observation of modestly high prevalence of impaired glucose tolerance in areas with low prevalence of diabetes indicate risk of early stage of diabetes epidemics.

Today it’s critical for providers to devote time to patient education; inform patients about their conditions and how to prevent, treat, and manage them. Proper management of chronic conditions extends well beyond episodic and infrequent visits to a provider’s office. This population health white paper discusses why patients must become responsible for their day-to-day disease management. Patients will frequently be required to self-monitor their health indicators, observe symptoms, and note behavior, but they must also adhere to complex medication regimens
Predictive and Preventive Care: Metabolic Diseasesasclepiuspdfs
South Asians have a very high incidence of ischemic heart disease and stroke. In addition, they also have a very high incidence of metabolic diseases such as prehypertension, hypertension, visceral obesity, metabolic syndrome, prediabetes, type-2 diabetes, and its clinical complications. Currently, there are over 75 million diabetic subjects in India and an equal number of prediabetics. Republic of China has taken over India as the diabetes capital of the world, with over 115 million diabetics. Modern medicine is disease focused and has failed to address the prevention of these chronic diseases. According to the reports from the United Nations (Millennium Development Goals [MDGs], the World Health Organization, Global Health Initiatives, and the non-communicable disease risk task force), obesity has increased by 2-fold and type-2 diabetes by 4-fold worldwide. Experts in this field predict that chances of meeting the MDGs set by the UN members of reducing the incidence of these diseases at 2025 to the level of 2020 are very little. Western medicine has failed to reduce or reverse the trend in the incidence of these diseases. We feel that an integrated approach to health care may be a better option, to reduce the disease burden in developing and resource-poor countries. Having said that, one cannot prevent something that one is not aware of, as such it is the need of the hour for us, to develop a robust predictive and preventive health-care platform. In an earlier article, we presented our views on reducing or reversing cardiometabolic diseases. There is great enthusiasm among the health-care providers and professional bodies that integration of emerging technologies will help develop personalized, precision medicine, as well as reduce the cost of health-care worldwide.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Introduction
Medicine today already contemplates the use of molecular markers to predict health risks.
Glucose and cholesterol measurements, for example, are standard of care. However, whereas
these are good screening tests for occult disease, they are not necessarily 'predictive' of future
events. Genomic information provides the opportunity to develop and refine the prediction for
risk and increase the precision of that prediction for the individual. Sir William Osler recognized
that "variability is the law of life, and no two individuals react alike and behave alike under the
abnormal conditions which we know as disease." [1]
We now have a new set of tools that can be used to understand biological and disease
variability. However, health and disease management today are further complicated by a
pharmaceutical industry that has developed medications using a one‐size‐fits‐all paradigm rather
than medications tailored to human variability. Thus, in medical practice today, many drugs work
in fewer than 50% of the patients to whom they are prescribed. Furthermore, more than 100,000
people die annually from drug‐related adverse events [1] A more personalized or customized
approach to medical care might be part of the solution to these healthcare woes.
What is personalized Medicine
Personalized medicine is a rapidly advancing field of healthcare that is informed by each
person's unique clinical, genetic (DNA‐based), genomic (whole genome or its products), and
environmental information. [2] The goals of personalized medicine are to take advantage of a
molecular understanding of disease to optimize preventive healthcare strategies and drug
therapies while people are still well or at the earliest stages of disease. Because these factors are
different for every person, the nature of disease, its onset, its course, and how it might respond
to drug or other interventions are as individual as the people who have them. For personalized
medicine to be used by healthcare providers and their patients, these findings must be translated
into precision diagnostic tests and targeted therapies. Because the overarching goal is to optimize
medical care and outcomes for each individual, treatments, medication types and dosages,
and/or prevention strategies may differ from person to person ‐‐ resulting in unprecedented
customization of patient care. [3]
What is Genomic Medicine?
Genomic medicine is an essential component of the broader personalized medicine
concept. Simply defined, it is the use of genomic information to guide medical decision making.
[4]The prospect of examining a person's entire genome (or at least a large fraction of it) to make
individualized risk predictions and treatment decisions is tantalizingly within reach.
Scientists have made extensive progress over the last two decades in understanding
human genetics and the role of proteins and chemicals in gene behavior. In 1989, the National
Institutes of Health launched the Human Genome Project (HGP) in an effort to identify the basic
building blocks for human beings. By 2003, investigators had sequenced the genome and
identified three billion discrete “chemical units.” [5]

between DNA sequence variations and human disease. Please refer to Figure 1. [3] They key
break through here would to reduce the cost to below $1,000 and time to few hours.
Rapid, low cost, and accurate secondary analysis
Once a genome is sequenced, it must be assembled into a complete genome. It is typically
done using supercomputers and takes several days to complete. During secondary analysis, raw
reads are assembled to form a complete genome, allowing scientists to from a complete picture
of an individual’s genetic variations. The process is similar to putting together jigsaw puzzle with
billions parts. The cost of this step could reach up to $10,000 per genome factoring in
infrastructure, supercomputers, trained bioinformaticians. [8]
In addition, there is the data storage question. Recently, the new technologies are able to
assemble a complete genome in a few hours with accuracy and low cost. While creating a single
genome creates terabytes of raw data, data from assembled genome that has gone through
secondary analysis cuts that data a thousand fold to merely gigabytes. As a result, secondary
analysis is also the area in which big data, high‐performance computing, and genomics really start
to overlap. Recent innovations in the former two categories are what make secondary analysis
possible in four hours or less.
Connecting the dots between genetic mutations and disease (Tertiary Analysis)
Completed genomes and their identified genotype then need to be interpreted for
biological relevance. This is where a certain mutation (or set of mutations) is matched with a
certain disease or physical trait (phenotype). This is a big data problem, whether establishing
standard processes and putting some real horsepower behind it will make it possible to perform
effective tertiary analysis. Essentially, we have to create software tools to enable scientists and
clinicians to extract maximum biological meaning from complex genomic data. The key
breakthrough here is the ability to identify specific disease phenotypes that are linked to specific
genotypes — connecting specific mutations to specific markers — in a repeatable way.
Injecting genetic information into medical care
Now that the patient’s genome have sequenced, and identified the list of candidate
mutations, the next step is to combine this knowledge with other medical factors — the patient’s
history, environment, family background, microbiome, diet, etc. Improving patient care and
developing personalized therapies depends on intelligently leveraging complex molecular and
clinical data from a variety of internal, external, and public sources. The key innovation at this
juncture is mainly cultural. Genomic data needs to be integrated with patient health records so
that it can be interpreted by trained physicians who can put genomic insights in wider context.
The goal is nothing less than redefining disease at the molecular level and integrating this data
with patient histories.
The challenges here are several. Again, there are no standard protocols for pulling this
information together in a common environment. Today, too many databases exist in isolation
5.
and are not cross‐mineable. Even basic availability is an issue, not to mention structure,
formatting, and method of data delivery. This summer Google announced plans to create a
database of human genetic information to streamline processes. Beyond alleviating a storage
burden though, by collecting so much medical information in one open space, such as cloud,
doctors have much more research to refer to when trying to help patients. One example would
be to figuring out what drugs might work best against what cancers by comparing a patient with
similar stored genomes. [9]
Here’s a simple chart spelling out the phases of escalation as the genomics landscape matures
and draws closer to realizing our long‐held vision of personalized medicine. [8]
Talent and investment dollars have already started to flow downstream in an effort to address
the challenges that cheap and fast sequencing has itself created — namely, taking piles upon
piles of data and deriving insights from that pipeline raw material. There’s a huge opportunity
right now, again, at the intersection of high‐performance computing, big data, and genomics.
The Challenges of Enabling Personalized Medicine
There are a number of challenges that can hinder the pace of advancement and ability to
gain the benefits of personalized medicine. Some of the issues are discussed here:
Regulatory Policy
Regulatory processes will be strained by genomic discoveries. There will be no way to conduct
conventional clinical studies for every genetic signature as a unique diagnostic test. FDA policies
pertaining to personalized medicine tests, pharmaceuticals, and companion diagnostics are
important and will determine the pace. One solution would be a statistical strength standard that
must be demonstrated before genetics can be applied to medical decision‐making. Statistical
strength could be determined through mining of federated data pools. This mechanism could
alleviate capacity constraints and costs associated with clinical studies and speed innovation to
the marketplace. [6]
Interoperability
Interoperability represents a major challenge because of the difficulty of integrating data from
different sources. If researchers and healthcare providers are not able to exchange information,
6.
it raises the cost of health care and makes it difficult to learn in real‐time. A considerable amount
of medical information is collected, but too little of it is integrated or put into databases that are
usable for research or public health purposes. [3]
Medical Education
As personalized medicine becomes a reality in mainstream medical practice, physicians and other
health care providers will have to advise on the application of growing numbers of molecular and
genetic tests and pharmacogenomically‐guided drugs, make treatment decisions based on more
predictive evidence, use information systems for managing patient care, and deal with new
ethical and legal issues. The adoption will depend heavily on the degree to which the provider
community is educated in the field and is prepared to engage in medical practice focused on risk
assessment and predictive/prognostic modeling. [10]
Health Information Technology
As our understanding of diseases becomes ever more stratified by their genomic signatures, even
larger data sets will be needed to establish treatment protocols. Patient data across geography
and health care plans will need to be queried simultaneously. This can only be achieved through
large, federated pools of information that includes patient genomic data and their health
histories.
Privacy Concerns
Legitimate concerns over privacy and confidentiality complicate secondary use of health care
information. Even when data are aggregated and depersonalized, it is hard for researchers to
gain access to information that helps spot trends or gain insights into public health trends.
Coverage and Payment Policy
There also are problems in terms of reimbursement policies. Many programs are not well aligned
with laudatory goals such as preventive medicine or positive health outcomes. This mismatch
makes it difficult to judge quality or build incentives for healthy outcomes. We need to reward
providers for good behavior and reduce incentives for wasteful or unnecessary treatment. [6]
Looking ahead
We are moving from the inefficient and experimental medicine of today towards the data‐
driven medicine of tomorrow. Soon, diagnosis, prognosis, treatment, and most importantly,
prevention will be tailored to individuals’ genetic and phenotypic information. [8] As we enter
the second decade of the 21st century, investments in molecular biology, bioinformatics, disease
management and the unraveling of the human genome are all finally bearing fruit. Additionally,
the collection, processing, and storing of molecular information will become a new and significant
driver of demand for information technology. Personalized medicine promises to revolutionize
the practice of medicine, transform the global healthcare industry, make healthcare affordable
and ultimately lead to longer and healthier lives. [11]
