SAN FRANCISCO -- In the movie The Social Network, the character of Peter Thiel is played as a slick Master of the Universe, a tech industry king and kingmaker with the savvy to see that a $500,000 investment in Facebook could mint millions later.
Reality is a little more rumpled.
On a recent December night, Thiel walked, slightly stooped, across a San Francisco stage to make a pitch to an invitation-only audience of Silicon Valley luminaries - investors and innovators who had scored sometimes huge fortunes through a mix of skill, vision and risk-taking.
The billionaire PayPal co-founder didn't tell them about the next big startup. He wanted them to buy into a bigger idea: the future.

Hand-Washing May Have Kept Flu at Bay

Good hygiene is simply the best protection from infectious agents, experts say

THURSDAY, Dec. 29 (HealthDay News) -- Following mothers' advice may have played a big role in averting a major health crisis.
Fears of the H1N1 flu virus reached a fever pitch last winter, with public health officials fearing a widespread outbreak caused by short supplies of the needed vaccine. But an epidemic was averted, and some health experts believe that's because more people than ever before regularly washed their hands./.../
Hand-washing in the United States has become a widespread habit, according to the American Society for Microbiology and the American Cleaning Institute. They released a study in September finding that 85 percent of people washed their hands in public restrooms in 2008, the highest levels observed since they began researching hand-washing habits in 1996.
And though there's no direct scientific evidence that hand-washing fended off H1N1 long enough for a vaccine to be developed and distributed, the head of the American Public Health Association said he believes that good hygiene very likely played a prominent role in the virus never catching fire in the United States.

Busted well: 4.9 million

The number of barrels of crude oil that spilled into the Gulf of Mexico following the explosion that destroyed BP's Deepwater Horizon well. Eleven of its crew died. For three mishap-prone months the company tried, and repeatedly failed, to plug its runaway well. Meanwhile, the crude poured forth, wreaking havoc on deep-water fish, migrating baby sea turtles, and BP chief executive Tony Hayward's career./.../

Papel da dopamina no sistema de recompensa do cérebro ajuda a entender os problemas de compulsão associados a dependência

A selective role for dopamine in stimulus-reward learning

Mecanismos da compulsão
Uma nova descoberta sobre o papel do neurotransmissor dopamina no sistema de recompensa do cérebro poderá ajudar a compreender melhor os problemas de compulsão associados a dependência e a diversos distúrbios psiquiátricos.

O estudo, feito por cientistas das universidades de Michigan e deWashington, nos Estados Unidos, concluiu que, ao contrário do que se estimava, diferenças nos tipos de resposta a estímulos ambientais entre indivíduos podem influenciar padrões químicos no cérebro relacionados à recompensa./.../

Metbolic Syndrome

Arguments continue over the metabolic syndrome

JULY 27, 2010 | Sue Hughes
New York, NY - Years after the term metabolic syndrome was first coined, controversy continues over the validity of naming and treating this clustering of certain risk factors as a separate condition. While different organizations use different definitions, metabolic syndrome is generally defined as having any three of the following: increased waist circumference, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, or elevated fasting glucose.
But for almost as long as the metabolic syndrome has been around, disagreement over its relevance has pitted some of the diabetes community against some of those in cardiology. This came to a head in 2005 when the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) issued a statement discouraging the use of the term metabolic syndrome, and then just a few weeks later, the American Heart Association (AHA) and the National Heart, Lung, and Blood Institute (NHLBI) released their own statement encouraging use of the metabolic-syndrome concept. Five years later, it appears that little has changed, with arguments still raging over whether there is any point in identifying and labeling individuals with this clustering of risk factors./.../

Veggie Diet Best for Kidney Patients

By Kristina Fiore, Staff Writer, MedPage Today
Published: December 26, 2010
Reviewed by Robert Jasmer, MD; Associate Clinical Professor of Medicine, University of California, San Francisco.

Action Points  
  • Explain that in patients with chronic kidney disease, a grain-based vegetarian diet may be better than a meat-based diet in terms of holding down phosphorus levels.
  • Note that those on the grain-based diet ingested the same amount of phosphorus as those on the meat-based diet.
A grain-based vegetarian diet may be better than a meat-based diet in terms of holding down phosphorus levels in patients with chronic kidney disease, according to results from a small crossover study.
Even though they ingested the same amount of phosphorus, patients on the vegetarian diet had lower serum phosphorus levels as well as other markers of improved phosphorus metabolism, Sharon Moe, MD, of Indiana University in Indianapolis, and colleagues reported in the Journal of the American Society of Nephrology./.../

The cultural genome

Google Books reveals traces of fame, censorship and changing languages

December 20, 2010
Source: Discover, Dec 16, 2010
[+]Harvard University researchers have been analyzing the more than 15 million books scanned by Google, which created a massive electronic library that represents 12% of all the books ever published.
As the team says, the corpus “will furnish a great cache of bones from which to reconstruct the skeleton of a new science.”
There are strong parallels to the completion of the human genome. Just as that provided an invaluable resource for biologists, Google’s corpus will allow social scientists and humanities scholars to study human culture in a rigorous way. There’s a good reason that the team is calling this field “culturomics.”
The team has tracked and stored the frequency of billions or words, or sets of words, over time. The result is a “big table” that you can download and explore at Otherwise, you can play around with Google’s real-time browser.
The team also found that new technology permeates through our culture with growing speed. By scanning the corpus for 154 inventions created between 1800-1960, from microwave ovens to electroencephalographs, they found that more recent ones took far less time to become widely discussed.

ICD-10 Ramps Up

Year in Review: ICD-10 Ramps Up

By Joyce Frieden, News Editor, MedPage Today
Published: December 23, 2010
As part of the Year in Review series, MedPage Todayreporters are revisiting major news stories and following up with an analysis of the impact of the original report, as well as subsequent news generated by the initial publication. Here's what's happened on the ICD-10 front since we published the first 2010 piece on the topic.
Earlier this year, officials at the Centers for Medicare and Medicaid Services (CMS) declared that Oct. 1, 2013 would be the firm implementation date for ICD-10, the newest iteration of the International Classification of Diseases (ICD) coding system used on medical claim forms.
The question then became how to handle the transition from ICD-9 to ICD-10, especially when it came to updating each set of codes during the transition./.../

Progressive commercialization of American medicine

by Lucas Restrepo, MD

There is only one fundamental problem with American medicine: its progressive commercialization.
Every other problem derives from it centrifugally. Medicine, wroteWilliam Osler, is “a calling, not a business.” Patients are not clients, nor physicians businessmen. People do not spend over a decade studying medicine ―living years in poverty or overburdened with debt― merely hoping to get rich. While it is perfectly legitimate to expect a salary that enables a dignified living and financial stability, any medical student who dreams a life of luxury is misguided. Even doctors or nurses in private practice rarely consider their call a conduit to personal wealth. People become health care providers for many reasons that can’t be encompassed with a neat word; however, altruism can’t be absent from anybody’s list./.../

Variability in the Measurement of Hospital-wide Mortality Rates

David M. Shahian, M.D., Robert E. Wolf, M.Sc., Lisa I. Iezzoni, M.D., Leslie Kirle, M.P.H., and Sharon-Lise T. Normand, Ph.D.

N Engl J Med 2010; 363:2530-2539December 23, 2010
Hospital-performance metrics are increasingly used for value-based purchasing and public reporting. For example, Section 3001 of the Patient Protection and Affordable Care Act mandates incentive payments to hospitals that meet quality performance standards, which remain unspecified.
In 2008, the Massachusetts Health Care Quality and Cost Council1 directed the Division of Health Care Finance and Policy (DHCFP) to study various approaches to estimating hospital-wide mortality rates as performance metrics. Medicare released hospital-wide mortality rates for its beneficiaries beginning in 1986 but suspended publication of the rates in 1993 because of methodologic concerns.2,3 The United Kingdom, various European countries, and Canada currently publish variants of such metrics, but questions remain regarding their clinical rationale, their usefulness for informing consumers and practitioners, and statistical methods for calculating them.4-6
In response to the council's mandate, the DHCFP initiated systematic evaluations of various methods for calculating hospital-wide mortality rates.7 At the DHCFP's request, we studied four such commercial methods./.../
