Washington, January 7, 2010 – The American College of Physicians (ACP) today sent a letter to key legislators urging them to ensure that the final health care reform bill includes provisions to support the primary care workforce.

"Recent studies show that the U.S. faces a shortage of more than 40,000 primary care physicians, even before taking into account increased demand for primary care associated with increased coverage," said ACP President Joseph W. Stubbs, MD, FACP in the letter.

RICHLAND, Wash. – A new acoustic telemetry system tracks the migration of juvenile salmon using one-tenth as many fish as comparable methods, suggests a paper published in the January edition of the American Fisheries Society journal Fisheries. The paper also explains how the system is best suited for deep, fast-moving rivers and can detect fish movement in more places than other tracking methods.

The inviting expanse of shimmering snow contrasts with the benign blue sky above. The ski instructor briefly goes over the planned run, his first charge glides off into the distance … and sets off a slab avalanche. The group all look on helplessly as their friend is buried under a wall of snow. Bernhard Budaker of the Fraunhofer Institute for Manufacturing Engineering and Automation IPA knows this kind of scenario is all too common.

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated.

"Climate models must take this carbon sink into account," says Mario Lebrato, lead author of the study. The work was done when he was at the National Oceanography Centre, Southampton (NOCS) and affiliated with the University of Southampton's School of Ocean and Earth Science (SOES); he is now at the Leibniz Institute of Marine Science in Germany.

Frailty is a geriatric condition marked by weight loss, low energy and strength, and low physical activity. UCLA researchers followed 1,072 healthy adults aged 70 to 79 between 1988 and 1991 to determine if productive activities — specifically volunteering, paid work and child care — prevent the onset of frailty.

University of Florida urologists have used robot-assisted surgery to cut about 20 minutes off average surgery time for conventional vasectomy reversal using a microscope.

Sperm count after surgery is comparable over a year for the two procedures, but the robotic procedure appears to result in a quicker return of sperm count.

"For a couple that's trying to get pregnant, this is a big deal," said Sijo Parekattil, M.D., director of male infertility and microsurgery at UF, who led the study.

A Massachusetts General Hospital (MGH) study has found that relatively young men with longstanding HIV infection and minimal cardiac risk factors had significantly more coronary atherosclerotic plaques – some involving serious arterial blockage – than did uninfected men with similar cardiovascular risk. The investigation appearing in the January 2010 issue of the journal AIDS is the first to use CT angiography to identify coronary artery plaques in HIV-infected participants.

INDIANAPOLIS – Frequent testing and treatment of infection does not reduce the prevalence of chlamydia in urban teenage girls, according to a long term study by Indiana University School of Medicine researchers published in the January 1, 2010 issue of the Journal of Infectious Diseases.

Viruses love plane travel. They get to fly around the world inside a closed container while their infected carrier breathes and coughs, spreading pathogens to other passengers, either by direct contact or through the air. And once people deplane, the virus can spread to other geographical areas.

ANN ARBOR, Mich. -- When it comes to pumping up the appeal of plug-in hybrid electric vehicles (PHEVs), some regions are more ripe for the cars than others, and some consumers' buttons need more pushing than others – an important policy distinction when shaping subsidies, two energy policy experts say.

Amid concerns regarding terrorists targeting airliners using weapons less detectable by traditional means, the Transportation Security Administration (TSA) is ramping up deployment of whole body scanners at security checkpoints in U.S. airports. These systems produce anatomically accurate images of the body and can detect objects and substances concealed by clothing.

To date, TSA has deployed two types of scanning systems:

High antiretroviral therapy adherence, which has been shown to be a major predictor of HIV disease progression and survival, is now associated with lower health care costs, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers examined the effect of antiretroviral therapy adherence on direct health care costs and found that antiretroviral therapy improves health outcomes for people infected with HIV, saving a net overall median monthly health care cost of $85 per patient.

Scientists in Texas are reporting the development of a "nanodragster" that may speed the course toward development of a new generation of futuristic molecular machines. The vehicle — only 1/50,000th the width of a human hair — resembles a hot-rod in shape and can outperform previous nano-sized vehicles. Their report is in ACS' Organic Letters, a bi-weekly journal.
