First, the bad news: all across America, trucks and tractor-trailers are transporting industrial explosives on nearly every artery of the country's interstate and highway system. That's right, volatile explosives, including munitions, rocket motors, and dynamite, are moving at a high rate of speed down a roadway not too far from you.

Rochester, MN, March 1, 2012 – Opioids are a mainstay of care in the critical care unit, but their use frequently causes constipation which can lead to adverse outcomes including delayed feeding and later discharge from the ICU. Researchers from London, UK, and Chicago, IL, have found that methylnaltrexone (MNTX), a peripheral opioid antagonist, may restore bowel function in critically ill patients. Their retrospective study appears in the March issue of Mayo Clinic Proceedings.

Italian and Swiss researchers confirm that induced hyperammonaemia significantly increases daytime sleepiness in patients with cirrhosis. The findings available in the March issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases, show that higher blood levels of ammonia reduced the ability of cirrhotic patients to produce restorative sleep.

COLLEGE PARK, Maryland - The Israeli public is wary of launching airstrikes aimed at disrupting Iran's ability to develop nuclear weapons, reports a new public opinion poll by researchers at the University of Maryland.

Only 19 of percent of all Israelis favored a go-it-alone strike by Israel, while 42 percent supported a strike only with U.S. backing, and 34 percent opposed any strike. Survey findings for Israeli Jews closely paralleled the results for the entire population of the nation.

DARIEN, IL – Aging does not appear to be a factor in poor sleep, a new survey of more than 150,000 Americans shows. In fact, subjective sleep quality seems to improve over a lifetime, with the fewest complaints coming from people in their 80s.

"This flies in the face of popular belief," said Michael Grandner, PhD, lead author of the study. "These results force us to re-think what we know about sleep in older people – men and women."

Although a recent study suggests that women with normal results on dual-energy X-ray absorptiometry (DXA) scans at ages 67 and older may wait up to 15 years for a second test, a Viewpoint article published today in the Journal of Bone and Mineral Research (JBMR) cautions that such a lengthy interval is inappropriate for many adults.

HOUSTON - A drug that relieves the severe symptoms of a life-threatening bone marrow cancer called myelofibrosis also improves the survival of patients with the disease, according to a phase III clinical trial published in the March 1 edition of New England Journal of Medicine.

STANFORD, Calif. — People with a blood cancer — myelofibrosis — can benefit from a drug called ruxolitinib, according to a randomized, double-blind, placebo-controlled clinical trial that included patients and researchers from the Stanford University School of Medicine. The results of the multi-site phase-3 trial, which will be published in the March 1 issue of the New England Journal of Medicine, led the Food and Drug Administration to approve the drug in November as treatment for people with intermediate or advanced cases of the disease.

COLUMBIA, Mo. – Many leading causes of death are linked to unhealthy lifestyle behaviors, including inadequate physical activity. Adults in minority populations have lower levels of physical activity and higher rates of preventable deaths, according to the Department of Health & Human Services. In a new study, University of Missouri researchers found that minority adults who received exercise interventions increased their physical activity levels. However, these interventions are not culturally tailored to best assist minority populations in improving overall health.

Patients who had leaky mitral heart valves repaired along with bypass surgery had with healthier hearts than those who had bypass only, according to new research presented in the American Heart Association's Emerging Science Series webinar.

The mitral valve separates the heart's left atrium (upper chamber) from the left ventricle (lower chamber). It has two flaps, or cusps, and if the flaps don't close properly, the valve will leak.

Language barriers could deter more than 100,000 Californians from enrolling in the Health Benefit Exchange, according to a study released today by the California Pan-Ethnic Health Network, the UCLA Center for Health Policy Research, and the UC Berkeley Center for Labor Research and Education.

SALT LAKE CITY — A team of global scientists, led by researchers at Intermountain Medical Center in Salt Lake City, has developed a safer and more accurate way to administer warfarin, one of the most commonly prescribed but also potentially dangerous medications in the United States.

As part of a worldwide study, the research team developed and tested a new formula that combines individual genetic data with a mathematical model to help physicians more accurately predict patient response to the popular blood-thinning drug.

The number of people living in China's cities, which last year for the first time surpassed 50 percent of the national population, is considered a boon for the consumer goods market. That is based on the assumption that there will be more families with more disposable income when poor farmers from China's countryside move to cities and become middle-class industrial and office workers.

But the assumption overlooks a policy from the era of Chinese leader Mao Zedong that restricts the upward mobility of its rural citizens, says a University of Washington geographer.

The latest official unemployment figures show that unemployment among young people has soared to 22.3 per cent, higher than the recession of the 1990s, while the overall unemployment rate is nine per cent. New research from Understanding Society, a study of more than 40,000 UK households, has examined what is driving this uneven employment pattern and finds that young people suffer from a 'double-penalty' in their attempts to find and keep a job.

Lower back pain due to Modic changes can be hard to treat and the currently recommended therapy of exercise and staying active often does not help alleviate the pain. Results of a trial, published in BioMed Central's open access journal BMC Medicine, comparing exercise therapy, and staying active, to daily rest and lumbar support, showed that both treatments resulted in the same small level of improvement in pain, disability, and general health.
