An international study, led by researchers at the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU) at the University of Southampton, has found that obese patients who undergo bariatric surgery are not at an increased risk of broken bones in the first few years after the operation. However, the study, published in the British Medical Journal today (DATE) has shown that there is a possibility of an increase in fracture risk after three to five years. Generally, a higher Body Mass Index (BMI) protects the bone against most types of fracture because a higher ...

A Yale study of the care quality received at safety-net hospitals — which provide care for the majority of uninsured and other vulnerable populations — found that quality at these facilities is similar to non-safety-net hospitals. This is despite the unique financial challenges at safety-net hospitals in the face of rising costs and the potential impact of the health care law. Published in the August issue of Health Affairs, the study was conducted by Elizabeth E. Drye, M.D., of the Yale Center for Outcomes Research and Evaluation, Joseph S. Ross, M.D., assistant professor ...

OAKLAND, Calif., August 6, 2012 – Long-term use of commonly used blood pressure medications that increase sensitivity to sunlight is associated with an increased risk of lip cancer in non-Hispanic whites, according to a Kaiser Permanente study that appears in the current online issue of Archives of Internal Medicine. Funded by the National Cancer Institute, the study found that photosensitizing antihypertensive drugs such as nifedipine and hydrochlorothiazide were associated with cancer of the epithelial cells known as squamous cells—which are the main part of the outermost ...

Implantable cardioverter defibrillators account for one-third of the decrease in cardiac arrests caused by ventricular fibrillation in North-Holland, according to research in Circulation, an American Heart Association journal. VF is an abnormal heart rhythm that makes the heart quiver so it can't pump blood. ICDs are small electronic devices implanted in the chest that detect potentially fatal abnormal heart rhythms and try to stop them with electric shocks. Generally, only people with a high risk of sudden cardiac death — mostly those at high risk of abnormal heartbeats ...

Hospitals in areas with large minority populations are more likely to be overcrowded and to divert ambulances, delaying timely emergency care, according to a multi-institutional study focused on California. The researchers examined ambulance diversion in more than 200 hospitals around the state to assess whether overcrowding in emergency rooms disproportionately affects racial and ethnic minorities. They found that minorities are more at risk of being impacted by ER crowding and by diversion than non-minorities. The study will be published in the August issue of Health ...

Most earthquakes in the Barnett Shale region of north Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according to new research from The University of Texas at Austin. None of the quakes identified in the two-year study were strong enough to pose a danger to the public. The study by Cliff Frohlich, senior research scientist at the university's Institute for Geophysics, appears this week in the journal Proceedings of the National Academy of Sciences. "You ...

AMHERST, Mass. – By some estimates, a third of the Earth's organisms by mass live in our planet's rocks and sediments, yet their lives and ecology are almost a complete mystery. This week, microbiologist James Holden at the University of Massachusetts Amherst and others report in Proceedings of the National Academy of Sciences the first detailed data about a group of methane-exhaling microbes that live deep in the cracks of hot undersea volcanoes. Holden says, "Evidence has built over the past 20 years that there's an incredible amount of biomass in the Earth's subsurface, ...

Baltimore, MD — The study of muscular system protein myostatin has been of great interest to researchers as a potential therapeutic target for people with muscular disorders. Although much is known about how myostatin affects muscle growth, there has been disagreement about what types of muscle cells it acts upon. New research from a team including Carnegie's Chen-Ming Fan and Christoph Lepper narrows down the field to one likely type of cell. Their work is published the week of August 6 by Proceedings of the National Academy of Sciences. Myostatin is known to inhibit ...

ITHACA, N.Y. – A colorful, fruit-eating bird with a black mask, pale belly and scarlet breast – never before described by science – has been discovered and named by Cornell University graduates following an expedition to the remote Peruvian Andes. The Sira Barbet, Capito fitzpatricki, is described in a paper published in the July 2012 issue of The Auk, the official publication of the American Ornithologists' Union. The new species was discovered during a 2008 expedition led by Michael G. Harvey, Glenn Seeholzer and Ben Winger, young ornithologists who had recently graduated ...

Using just an upgraded desktop computer equipped with a relatively inexpensive graphics processing card, a team of computer scientists and biochemists at the University of California, San Diego, has developed advanced GPU accelerated software and demonstrated for the first time that this approach can sample biological events that occur on the millisecond timescale. These results have the potential to bring millisecond scale sampling, now available only on a multi-million dollar supercomputer, to all researchers, and could significantly impact the study of protein dynamics ...

MINNEAPOLIS (August 6, 2012) – University of Minnesota School of Public Health researchers have found that medical group practices can reduce costs for patients with diabetes by investing in improved quality of care. In the study, which appears in the August issue of Health Affairs, University of Minnesota researchers analyzed 234 medical group practices providing care for more than 133,000 diabetic patients. After developing a "quality of care" score based on select patient care initiatives, researchers found that medical providers saved an average of $51 in health ...

In a large epidemiologic study, researchers at UCLA's Jonsson Cancer Center found that the children of U.S.-born Latina women are at higher risk of having retinoblastoma, a malignant tumor of the retina which typically occurs in children under six. The study, which focused on babies born in California, also found that offspring of older fathers were at greater risk for retinoblastoma, as were children born to women with sexually transmitted diseases and those born in multiple births, which may indicate an increased risk from in vitro fertilization. Those findings confirmed ...

(Santa Barbara, Calif.) –– Most people think of seafood as either wild or farmed, but in fact both categories may apply to the fish you pick up from your grocery store. In recent years, for example, as much as 40 percent of the Alaskan salmon catch originated in fish hatcheries, although it may be labeled "all wild, never farmed." An article produced by a working group of UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) recommends that when a combination of seafood production techniques are used, this be acknowledged in the marketplace. ...

CORVALLIS, Ore. – Young children who are able to pay attention and persist on a task have a 50 percent greater chance of completing college, according to a new study at Oregon State University. Tracking a group of 430 preschool-age children, the study gives compelling evidence that social and behavioral skills, such as paying attention, following directions and completing a task may be even more crucial than academic abilities. And the good news for parents and educators, the researchers said, is that attention and persistence skills are malleable and can be taught. The ...

Despite a twenty-five year old law that bans "patient dumping" the practice continues to put uninsured Americans at risk, according to a national team of researchers led by a professor at the George Washington School of Public Health and Health Services. Patient dumping is the practice of turning away or transferring uninsured patients with emergency medical conditions. The study, which appears in the August issue of Health Affairs, suggests that hospitals still practice "patient dumping" which is in violation of the law. The researchers investigate and present five ...

CHAMPAIGN, Ill. — A study from University of Illinois economics professors demonstrates a new method to analyze the relationships among voters' issue preferences, the candidates' policy positions and voter behavior. Estimating the distribution of voter preferences and the extent of policy divergence between the candidates' platforms, economics professors Stefan Krasa and Mattias Polborn are able to separate observed changes in voter behavior into those driven by voter radicalization versus those caused by increased policy differences between the two parties. "We have ...

Health coverage for the poorest Americans could be in jeopardy in many states as a result of the U.S. Supreme Court's ruling last month on the Affordable Care Act, according to a new legal analysis. The report examines federal and state Medicaid options following the United States Supreme Court's ruling in NFIB v Sebelius and appears in the August issue of the journal Health Affairs. "Some states will use the court's decision as an excuse to delay or refuse to participate in the expansion of Medicaid as outlined in the Affordable Care Act," says lead author of the report, ...

URBANA – The trade in ivory was largely outlawed in 1989, but poaching continues and remains a serious threat to the African elephant. Seizures of large amounts of ivory, sometimes over a ton, continue to occur. Research by Alfred Roca, an assistant professor at the university, could be the basis for the development of new law enforcement tools. Roca has found a way to determine where the ivory comes from. With funding from the Division of International Conservation of the U.S. Fish and Wildlife Service, he and his collaborators have sampled elephants at 22 locations ...

ZURICH — Though sophisticated three-dimensional imagery is abundant in computer-generated games and movies, a group of researchers from Disney Research, Zürich, University of California, San Diego, Limbic Software, and RWTH Aachen University say they have gained insights to improve the rendering of those images by envisioning a flat, two-dimensional world. The fundamental physics of light is easier to understand in that 2D world than in a 3D environment, they said, and enabled them to develop simplified equations for governing the behavior of light. This in turn allowed ...

When NASA's Aqua satellite captured an infrared view of the northwestern Pacific's latest tropical storm, Tropical Storm 13W, the data revealed the bulk of the heavy rainfall on the northern side of the center. NASA's Aqua satellite passed over Tropical Storm 13W on August 6 at 0205 UTC (Aug. 5 10:05 a.m. EDT). The Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the cloud temperatures that showed the strongest storms (purple) and heaviest rainfall north and east of the center of circulation. Infrared imagery shows temperature and the higher ...

Microbes, sponges, and worms—the side effects of pollution and heavy fishing—are adding insult to injury in Kenya's imperiled reef systems, according to a recent study by the Wildlife Conservation Society and the University of Azores. The authors of the study have found that pollution and overfishing on reef systems have an ecological cascading effect—the proliferation of microbes, sponges, and worms—that further degrade corals, a discovery that underlines the complexity of reefs and possible solutions. The study appears in the online edition of Marine Ecology Progress ...

The sixth tropical storm of the Atlantic Ocean hurricane season formed over the past weekend, and NASA kept an on its progression. Tropical Storm Florence was born in the eastern Atlantic and weakened when it interacted with dry air. On Friday, August 3, the low pressure area known as "System 90L" was being watched for development. It was located south of the Cape Verde Islands off the African coast. By the early evening (Eastern Daylight Time) it quickly organized. System 90L strengthened and became Tropical Storm Florence in the eastern Atlantic. Over August 4 and 5 ...

ZURICH — Scientists have yet to fully unravel the mysteries of rainbows, but a group of researchers from Disney Research, Zürich, UC San Diego, Universidad de Zaragoza, and Horley, UK, have used simulations of these natural wonders to unlock the secret to a rare optical phenomenon known as the twinned rainbow. Unlike the more common double-rainbow, which consists of two separate and concentric rainbow arcs, the elusive twinned rainbow appears as two rainbows arcs that split from a single base rainbow. Sometimes it is even observed in combination with a double rainbow. ...

"Pants on fire" isn't the only problem liars face. New research from the University of Notre Dame shows that when people managed to reduce their lies in given weeks across a 10-week study, they reported significantly improved physical and mental health in those same weeks. Funded by a grant from the John Templeton Foundation, the "Science of Honesty" study was presented recently at the American Psychological Association's 120th annual convention. "We found that the participants could purposefully and dramatically reduce their everyday lies, and that in turn was associated ...
