If you live in neighborhoods with access to grocery stores, healthy food, parks and a pleasant walking environment, you're more likely to be in ideal cardiovascular health.

That's the finding of research reported at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions.

WASHINGTON—March 14, 2012—More than half of likely voters doubt that the United States will be the No. 1 world leader in science, technology and health care by the year 2020, according to a new national public opinion poll commissioned by Research!America. The findings reveal deep concerns among Americans about the country's ability to maintain its world-class status in innovation, research and development before the next decade.

Developing nations experiencing economic and social growth might also see growing waistlines among their poorest citizens, according to a new study from Rice University and the University of Colorado.

The researchers found that while growth of developing countries may improve conditions such as malnutrition and infectious disease, it may increase obesity among people with lower socio-economic status.

Fecal transplantation through colonoscopy is an effective treatment for recurrent Clostridium difficile infection (CDI), according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. Additionally, the mortality rate in this study does not appear to be greater than in some previously reported series, suggesting that fecal transplantation itself seems to be a rather safe procedure. CDI is a common cause of both community- and hospital-acquired diarrhea, usually occurring after exposure to antibiotics.

DURHAM, N.C. -- One in four HIV patients was found to have been sexually abused as a child, according to a two-year Duke University study of more than 600 HIV patients. Traumatic childhood experiences were also linked to worse health outcomes among these patients, who are aged 20 to 71.

DURHAM, N.C. -- Candidates with lower-pitched voices may get more votes in the 2012 election.

A new study by biologists and a political scientist shows that both men and women prefer political candidates with deeper voices. The results also suggest that biology -- not just partisanship or ideology – can shape voters' choices.

"We often make snap judgments about candidates without full knowledge of their policies or positions. These findings might help explain why," said Duke University biologist Rindy Anderson.

Mobile phones could play a valuable role in helping HIV patients to take their medication every day, according to a new Cochrane Systematic Review. The researchers found that patients were less likely to miss doses if they were sent weekly mobile phone text message reminders.

Inadequate training or supervision of clinical staff and the absence of, or failure to follow clinical protocols were more important than a shortage of equipment or staff as causing harm to hospitalised patients in the developing world, claims a study published on bmj.com today.

The researchers estimate that on average, these failures account for more than one death per day in each hospital studied, the vast majority of which are preventable.

CHICAGO – Among hospitals in Ontario, Canada, those with higher levels of spending, which included higher intensity nursing and greater use of specialists and procedures, had an associated lower rate of deaths, hospital readmissions, and better quality of care for severely ill hospitalized patients, according to a study in the March 14 issue of JAMA.

CHICAGO – In the E coli outbreak in Germany in May 2011, treatment with azithromycin was associated with a lower frequency of long-term carriage of the bacteria and shorter duration of shedding of the bacteria in stool specimens, according to a study in the March 14 issue of JAMA.

A nightly breathing treatment may do more than help people with obstructive sleep apnea get a good night's rest — it may also help prevent heart failure.

In a study published in Circulation: Heart Failure, a journal of the American Heart Association, researchers in the U.K. discovered that moderate to severe obstructive sleep apnea (OSA) can cause changes in the heart's shape and function, similar to the effects of hypertension. These changes include increased mass, thickening of the heart wall and reduced pumping ability.

The odds of surviving their hospital stay for heart failure differ between Hispanic and non-Hispanic white patients according to their level of heart function, even when they received equal care in hospitals participating in the American Heart Association's Get With The Guidelines®–Heart Failure quality improvement program, researchers said.

COLLEGE PARK, Md. - Only one in four Americans favors Israel conducting a military strike against Iran's nuclear program, finds a new University of Maryland poll. Nearly seven in ten (69 percent) favor the United States and other major powers continuing to pursue negotiations with Iran, a position supported by majorities of Republicans (58 percent), Democrats (79 percent) and Independents (67 percent).

Might the "Twinkie defense" have a scientific foundation after all? Researchers at the University of California, San Diego School of Medicine have shown – by each of a range of measures, in men and women of all ages, in Caucasians and minorities – that consumption of dietary trans fatty acids (dTFAs) is associated with irritability and aggression.

CHICAGO (March 13, 2012) – According to the results of a new study published in the March 2012 issue of the Journal of the American College of Surgeons, patients who score highest on the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) experience longer postoperative hospital stays and more days in the intensive care unit (ICU); they are also more likely to return to the operating room (OR) within 30 days of a surgical procedure than patients with low AUDIT-C scores.
