Association of Coffee Drinking with Total and Cause-Specific Mortality [FULL TEXT HTML]: "We used data from a very large study, the National Institutes of Health (NIH)–AARP Diet and Health Study (ClinicalTrials.gov number, NCT00340015), to determine whether coffee consumption is associated with total or cause-specific mortality. The current analysis, involving more than 400,000 participants and 52,000 deaths, had ample power to detect even modest associations and allowed for subgroup analyses according to important baseline factors, including the presence or absence of adiposity and diabetes, as well as cigarette-smoking status."

This past August, producer Bryan Singer (The Usual Suspects, X-Men) launched a new digital series: H+. The premise: in the near future, 33% of humanity has retired their smartphones, tablets and computers in favor of an implanted computer system, H+, which connects them directly to the internet 24/7. The story begins as a computer virus attacks the implants, killing billions. In intersecting storylines across four continents (told in part through flashbacks,) the series then unravels what happened, who caused it and why. [more inside]

On November 30, the Tampa Bay Times published a sympathetic profile of Spring Hill, FL resident Gretchen Molannen: "Persistent genital arousal disorder brings woman agony, not ecstasy." Her condition, also known as PGAD, is a rare sexual disorder (not recognized by the DSM,) 'characterized by spontaneous, persistent, unwanted sexual arousal unrelated to feelings of sexual desire.' The Times reported that Ms. Molannen's condition had virtually destroyed her personal and professional life and led to several suicide attempts. One day after the article was published, she successfully committed suicide. [more inside]
Susannah Cahalan has a month-long gap in her memory from when she was struck by the little known disease anti-NMDA receptor encephalitis. Cahalan, a New York Post journalist, wrote an account of her ordeal shortly after it happened, and went on the Today Show to talk about it. Now she has written a book on her experience called Brain on Fire and wants to make people aware of the disease, and that was the subject of a follow-up segment on the Today Show. She is not the only person to have been afflicted. There is more information about the disease and the book on Cahalan's website. She was interviewed at length on NPR's Fresh Air earlier this month. Novelist and essayist Leslie Jamison has a well-written review of Brain on Fire and puts it in its literary context.

Nanoparticles covered in proteins trick immune system. A breakthrough new experimental treatment that uses nanoparticles covered with proteins to trick the immune system, managed to stop it attacking myelin and halt disease progression in mice with relapsing remitting multiple sclerosis (MS). The researchers say the approach may also be applicable to other auto-immune diseases such as asthma and type 1 diabetes.
"Why do parasites harm their hosts? Conventional wisdom holds that because parasites depend on their hosts for survival and transmission, they should evolve to become benign, yet many parasites cause harm. Theory predicts that parasites could evolve virulence (i.e., parasite-induced reductions in host fitness) by balancing the transmission benefits of parasite replication with the costs of host death. This idea has led researchers to predict how human interventions—such as vaccines—may alter virulence evolution, yet empirical support is critically lacking." Two papers demonstrate empirical evidence for related models predicting the origin of virulence: [more inside]
Heaven is Real: A Doctor's Experience of the Afterlife. As a neurosurgeon, I did not believe in the phenomenon of near-death experiences...In the fall of 2008, however, after seven days in a coma during which the human part of my brain, the neocortex, was inactivated, I experienced something so profound that it gave me a scientific reason to believe in consciousness after death.

Drug-resistant and "extensively" resistant strains make containment and treatment of tuberculosis ever more difficult. Fortunately, researchers based in Switzerland have (re-)discovered a naturally-made antibiotic called pyridomycin, which will kill isoniazid-resistant M. tuberculosis bacteria.
First published in 1997, Anne Fadiman's book The Spirit Catches You and You Fall Down, a chronicle of a Hmong refugee family's interactions with the American medical system in the face of a child's devastating illness, has become highly recommended, if not required, reading for many medical students and health care professionals, over the past 15 years quietly changing how young doctors approach patients from different cultures. On August 31, with little publicity, Lia Lee, the young girl who inspired the book, after living most of her life in a persistent vegetative state, quietly died [NYT obit].

Sudden death suddenly becomes a lot less pressing. A team of scientists at the Boston Children’s Hospital have designed a microparticle that can be injected into the bloodstream which rapidly oxygenates blood, capable of keeping a person alive for up to 30 minutes after respiratory failure. This will even work if the ability to breathe has been restricted, or cut off entirely. Here's how it works, in greater detail. This finding has the potential to save millions of lives every year, and can buy emergency medical personnel a significant amount of time to address what would otherwise be fatal emergencies. It also has numerous potential applications for the Defense Department, which is funding part of the research.

Friends of Science in Medicine (FSM) is a new advocacy group of senior medical practitioners and researchers seeking to drive "complementary and alternative medicines" from universities around Australia, and to make non-evidence based therapies ineligible for private health insurance.

Earlier this year, six scientists and doctors filed a lawsuit against the US Food and Drug Administration alleging that the FDA had secretly monitored their personal e-mail accounts after they (legally) warned Congress that the "agency was approving medical devices that they believed posed unacceptable risks to patients." The agency said it had done so to "investigate allegations that the employees had leaked confidential information to the public." At the time, the FDA indicated their computer monitoring was limited to five scientists. But now, the New York Times is reporting that "what began as a narrow investigation" "quickly grew in mid-2010 into a much broader campaign to counter outside critics of the agency’s medical review process.".

In less than an hour, the Supreme Court will hand down its final judgment in what has become one of the most crucial legal battles of our time: the constitutionality of President Obama's landmark health care reform law. The product of a strict party line vote following a
year century of debate, disinformation, and tense legislative wrangling, the Affordable Care Act would (among other popular reforms) require all Americans to buy insurance coverage by 2014, broadening the risk pool for the benefit of those with pre-existing conditions.
The fate of this "individual mandate," bitterly opposed by Republicans despite its similarity to past plans touted by conservatives (including presidential contender Mitt Romney) is the central question facing the justices today. If the conservative majority takes the dramatic step of striking down the mandate, the law will be toothless, and in danger of wholesale reversal, rendering millions uninsured, dealing a crippling blow to the president's re-election hopes, and possibly endangering the federal regulatory state.
But despite the pessimism of bettors, some believe the Court will demur, wary of damaging its already-fragile reputation with another partisan 5-4 decision.

"Adrian Owen still gets animated when he talks about patient 23. The patient was only 24 years old when his life was devastated by a car accident. Alive but unresponsive, he had been languishing in what neurologists refer to as a vegetative state for five years, when Owen, a neuro-scientist then at the University of Cambridge, UK, and his colleagues at the University of Liège in Belgium, put him into a functional magnetic resonance imaging (fMRI) machine and started asking him questions. Incredibly, he provided answers."
Since the U.S. Preventive Services Task Force recommended against screening for prostate cancer, the debate has been furious.

The emergence of a citation cartel. "Cell Transplantation is a medical journal published by the Cognizant Communication Corporation of Putnam Valley, New York. In recent years, its impact factor has been growing rapidly. In 2006, it was 3.482. In 2010, it had almost doubled to 6.204. When you look at which journals cite Cell Transplantation, two journals stand out noticeably: the Medical Science Monitor, and The Scientific World Journal. According to the JCR, neither of these journals cited Cell Transplantation until 2010. Then, in 2010, a review article was published in the Medical Science Monitor citing 490 articles, 445 of which were to papers published in Cell Transplantation. All 445 citations pointed to papers published in 2008 or 2009 — the citation window from which the journal’s 2010 impact factor was derived. Of the remaining 45 citations, 44 cited the Medical Science Monitor, again, to papers published in 2008 and 2009. Three of the four authors of this paper sit on the editorial board of Cell Transplantation. Two are associate editors, one is the founding editor. The fourth is the CEO of a medical communications company." (from Scholarly Kitchen, via Andrew Gelman.)

"Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets." After an extensive, months-long debate, one of two controversial papers showing ways the H5N1 "avian" influenza virus could potentially become transmissible in mammals with only 3 or 4 mutations was published in Nature today. The journal included an editorial on the merits and drawbacks of "publishing risky research" with regard to biosafety. The debate included an unprecedented recommendation by The US National Science Advisory Board for Biosecurity (NSABB) to block publication -- a decision they later reversed. (Via: 1, 2) Nature's special report has additional articles, including interviews with the teams behind both papers.
"We measure, in a single experiment, both the radiation pressure and the torque due to a wide variety of propagating acoustic vortex beams. The results validate, for the first time directly, the theoretically predicted ratio of the orbital angular momentum to linear momentum in a propagating beam. We experimentally determine this ratio using simultaneous measurements of both the levitation force and the torque on an acoustic absorber exerted by a broad range of helical ultrasonic beams produced by a 1000-element matrix transducer array." In other words, science has created the sonic screwdriver, and it could mean new advances in non-invasive surgery. [more inside]

Bombshell investigation reveals vast majority of landmark cancer studies cannot be replicated. In a shocking discovery, C. Glenn Begley, former researcher at Amgen Inc, and a team working with him, has found that 47 out of 53 so called "landmark" basic studies on cancer -- a high proportion of them from university labs -- cannot be replicated, with grim consequences for producing new medicines in the future. These were papers in top journals, from reputable labs, which achieved landmark status with frequent citations. The consequences for cancer research are far-reaching. [more inside]
Since 2000, the Centers for Disease Control and Prevention has based its estimates of how many children in the United States have autism on surveillance reports from its Autism and Developmental Disabilities Monitoring Network. Every two years, researchers count how many 8-year-olds have an autism spectrum disorder in about a dozen communities across the nation. According to a new report released by the CDC yesterday, (pdf), the latest data estimate that 1 in 88 American children has some form of autism spectrum disorder. (1 in 54 boys and 1 in 252 girls.) That's a 78% increase compared to a decade ago. The report, which analyzed data from 2008, indicates a 23 percent rise in diagnoses of ASDs over a two-year period. (Last link has autoplaying video)
This morning marked day two of marathon proceedings in what's likely the most momentous and politically-charged Supreme Court case since Bush v. Gore: the effort to strike down President Obama's landmark health care reform law. While yesterday was a sleepy affair of obscure technical debate, today's hearings targeted the heart of the law -- the individual mandate that requires most Americans to purchase insurance by 2014. With lower courts delivering a split decision before today, administration lawyers held some hope that at least one conservative justice could be persuaded to uphold the provision, which amortizes the risk that makes universal coverage possible. But after a day of deeply skeptical questioning by swing justice Anthony Kennedy and his fellow conservatives [transcript - audio], the mandate looks to be in grave trouble, with CNN legal analyst Jeffrey Toobin going as far as calling the day "a train wreck" for the administration. But it's far from a done deal, with a third day of hearings tomorrow and a final decision not expected until June.

"Nature is not always the best designer, at least when it comes to things that humans must build and maintain. So the newest artificial heart doesn’t imitate the cardiac muscle at all. Instead, it whirs like a little propeller, pushing blood through the body at a steady rate. After 500 million years of evolution accustoming the human body to blood moving through us in spurts, a pulse may not be necessary. That, in any case, is the point of view of the 50-odd calves, and no fewer than three human beings, who have gotten along just fine with their blood coursing through them as evenly as Freon through an air conditioner."
