Aspirin may lower melanoma risk

A new study has found that women who take aspirin have a reduced risk of developing melanoma—and that the longer they take it, the lower the risk. The findings suggest that aspirin's anti-inflammatory effects may help protect against this type of skin cancer. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

Pre-industrial hunter gatherers had clogged arteries too

Like nearly 4.6 million Americans, ancient hunter-gatherers also suffered from clogged arteries, revealing that the plaque build-up causing blood clots, heart attacks and strokes is not just a result of fatty diets or couch potato habits, according to new research in the journal The Lancet.

The researchers performed CT scans of 137 mummies from across four continents and found artery plaque in every single population studied, from preagricultual hunter-gatherers in the Aleutian Islands to the ancient Puebloans of southwestern United States.

Selectively manipulating protein modifications

Protein activity is strictly regulated. Incorrect or poor protein regulation can lead to uncontrolled growth and thus cancer or chronic inflammation. Members of the Institute of Veterinary Biochemistry and Molecular Biology from the University of Zurich have identified enzymes that can regulate the activity of medically important proteins. Their discovery enables these proteins to be manipulated very selectively, opening up new treatment methods for inflammations and cancer.

ECG screening for competitive athletes would not prevent sudden death

The risk of cardiovascular sudden death was very small and only about 30% of the incidence were due to diseases that could be reliably detected by pre-participation screening, even with 12-lead ECGs, according to research in a U.S. high school athlete population presented March 10 at the American College of Cardiology (ACC) Scientific Sessions.

Results released for first multicenter study of hybrid revascularization

The first multicenter study of hybrid revascularization shows that the emerging procedure for treating coronary artery disease has a similar rate of major adverse events in the first year, compared with percutaneous intervention (stenting).

Intermountain study finds length of DNA strands can predict life expectancy

SAN FRANCISCO – Can the length of strands of DNA in patients with heart disease predict their life expectancy?

Researchers from the Intermountain Heart Institute at Intermountain Medical Center in Salt Lake City, who studied the DNA of more that 3,500 patients with heart disease, say yes it can.

Biological tooth replacement -- a step closer

Scientists have developed a new method of replacing missing teeth with a bioengineered material generated from a person's own gum cells. Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant. The research is led by Professor Paul Sharpe, an expert in craniofacial development and stem cell biology at King's College London and published in the Journal of Dental Research.

Study shows confidence builds better exercise habits for cancer survivors

HOUSTON - Endometrial cancer survivors are more likely to complete physical activity, and for longer durations, when their daily self-efficacy is higher, according to a study published online in the journal Health Psychology – a publication of the American Psychology Association.

NIST panel expands recommendations for use of electronic health records in pediatrics

To speed development and adoption of electronic health records (EHRs) for pediatrics, a group of experts from industry, academia and government convened by the National Institute of Standards and Technology (NIST) has focused its attention on three key audiences—records-system vendors and developers, small-group pediatric medical practices and children's hospitals.

Why a hereditary anemia is caused by genetic mutation in mechanically sensitive ion channel

BUFFALO, N.Y. – A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper (http://bit.ly/13LgCzc) published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

Temp-controlled 'nanopores' may allow detailed blood analysis

Tiny biomolecular chambers called nanopores that can be selectively heated may help doctors diagnose disease more effectively if recent research by a team at the National Institute of Standards and Technology (NIST), Wheaton College, and Virginia Commonwealth University (VCU) proves effective. Though the findings* may be years away from application in the clinic, they may one day improve doctors' ability to search the bloodstream quickly for indicators of disease—a longstanding goal of medical research.

Emotion-health connection not limited to industrialized nations

Positive emotions are known to play a role in physical well-being, and stress is strongly linked to poor health, but is this strictly a "First World" phenomenon? In developing nations, is the fulfillment of basic needs more critical to health than how one feels? A new study shows that emotions do affect health around the world and may, in fact, be more important to wellness in low-income countries.

Partner abuse counseling for women insufficient

HERSHEY, Pa. -- Only about one in five central Pennsylvania women who have experienced intimate partner violence is asked or counseled by a health care provider about abuse, according to Penn State medicine and public health science researchers. Overall, approximately only one in nine women has received preventive counseling about violence and safety.

Hospitalizations for congenital heart disease increasing at greater rate among adults than children

Jared M. O'Leary, M.D., of Brigham and Women's Hospital, Boston, and colleagues analyzed U.S. hospitalizations from 1998 through 2010 for children and adults with congenital heart disease. "There are more than 787,000 adults with congenital heart disease in the United States. Adults with congenital heart disease remain at risk for frequent hospitalizations," the authors write in a Research Letter published online by JAMA to coincide with its presentation at the American College of Cardiology's annual Scientific Sessions.

Farmers who commit totally to sell locally can make a profit

UNIVERSITY PARK, Pa. -- Farmers can make a profit selling their produce directly to local businesses, but they must not let possible new costs weaken their commitment to the new venture, according to an international team of researchers.

"We found that the farmers who really made a conscious decision to sell local and who made more of a commitment tended to do better than those who are just testing the waters with local direct selling," said Amit Sharma, associate professor of hospitality management, Penn State.
