*Behavior strategies, such as self-monitoring and goals, motivate best, MU study finds*

COLUMBIA, Mo. – Most people know that exercise is important to maintain and improve health; however, sedentary lifestyles and obesity rates are at all-time highs and have become major national issues. In a new study, University of Missouri researchers found that healthy adults who received interventions focused on behavior-changing strategies significantly increased their physical activity levels. Conversely, interventions based on cognitive approaches, which try to change knowledge and attitudes, did not improve physical activity. (more…)

Heat Therapy Could Be New Treatment for Parasitic Skin Disease

COLUMBUS, Ohio – Scientists are hoping that heat therapy could eventually replace a complex drug regimen as the first-line treatment of a parasitic skin infection common in tropical and subtropical regions of the world.

The researchers successfully treated the skin infection with heat therapy in two patients whose immune systems were deficient, which lowered their bodies’ ability to respond to medication. Both patients have remained free of the parasitic disease, called cutaneous leishmaniasis, for more than a year since receiving the heat treatment.

That long-term effectiveness, especially in people with compromised immune systems, makes this one-time application of heat to skin lesions an appealing alternative to the conventional treatment for the infection — a series of about 20 consecutive daily drug injections that is rife with compliance problems, researchers say.

GAINESVILLE, Fla. — The psychological effects of the BP oil spill, the largest recorded environmental disaster in human history, extend far beyond people living around the areas of the Gulf of Mexico that were directly impacted by the spill, a new study finds.

Writing in the online edition of the journal Environmental Health Perspectives, a publication of the National Institutes of Health, the researchers reported that even in areas that did not have oil exposure, people still experienced elevated levels of anxiety and depression and reduced ability to show resilience in difficult emotional and financial situations because of the disaster.

Regrowing Hair: UCLA-VA Researchers May Have Accidentally Discovered a Solution

It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters’ “miracle solvents” to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness.

Now, a team led by researchers from UCLA and the Veterans Administration that was investigating how stress affects gastrointestinal function may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with hair loss — entirely by accident. (more…)

*Study shows western high-income countries have achieved impressive progress in lowering hypertension and cholesterol*

The worldwide prevalence of obesity has nearly doubled since 1980, according to a major study on how three important heart disease risk factors have changed across the world over the last three decades. The study, published on Feb. 4 in three papers in the Lancet, looked at all available global data to assess how body mass index, blood pressure and cholesterol changed between 1980 and 2008.

The study shows that in 2008, more than one in ten of the world’s adult population was obese, with women more likely to be obese than men. An estimated 205 million men and 297 million adult women were obese – a total of more than half a billion adults worldwide. (more…)

Patient Privacy Should be Respected Abroad and Online

GAINESVILLE, Fla. — Taking an unauthorized photo of a patient and posting it on Facebook is a giant no-no for health-care providers, who follow strict federal guidelines protecting patient privacy.

But what if the patient is a little girl in Ecuador receiving a vaccine from an American medical student, who’s in the country on a medical outreach trip? Although taking photos of patients in developing countries and posting them on the Web may not be illegal, it’s not ethical, say researchers from the University of Florida.

It’s long been a common practice for health care providers to snap photos while volunteering their time in developing countries, generally to bring back evidence of the conditions patients face there. But reporting in the Journal of Medical Internet Research, UF College of Medicine researchers say providers should treat patients’ privacy with the same reverence no matter where the care takes place.

Does Social Anxiety Disorder Respond to Psychotherapy? Brain Study Says Yes

When psychotherapy is helping someone get better, what does that change look like in the brain? This was the question a team of Canadian psychological scientists set out to investigate in patients suffering from social anxiety disorder. Their findings are published in Psychological Science, a journal of the Association of Psychological Science.

Social anxiety is a common disorder, marked by overwhelming fears of interacting with others and expectations of being harshly judged. Medication and psychotherapy both help people with the disorder. But research on the neurological effects of psychotherapy has lagged far behind that on medication-induced changes in the brain. (more…)
