Obesity Has Doubled Since 1980, Major Global Analysis of Risk Factors Reveals

*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…)

Quest for Designer Bacteria Uncovers a Spy

ANN ARBOR, Mich.—Scientists have discovered a molecular assistant called Spy that helps bacteria excel at producing proteins for medical and industrial purposes.

Bacteria are widely used to manufacture proteins used in medicine and industry, but the bugs often bungle the job. Many proteins fall apart and get cut up inside the bacteria before they can be harvested. Others collapse into useless tangles instead of folding properly, as they must in order to function normally.

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.

Why Are Vines Overtaking the American Tropics?

A Million-Dollar Question

Sleeping Beauty’s kingdom was overgrown by vines when she fell into a deep sleep. Researchers at the Smithsonian in Panama and the University of Wisconsin at Milwaukee received more than a million dollars from the U.S. National Science Foundation to discover why real vines are overtaking the American tropics. Data from eight sites show that vines are overgrowing trees in all cases. 

“We are witnessing a fundamental structural change in the physical make-up of forests that will have a profound impact on the animals, human communities and businesses that depend on them for their livelihoods,” said Stefan Schnitzer, research associate at the Smithsonian Tropical Research Institute in Panama and associate professor at the University of Wisconsin at Milwaukee.  (more…)

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…)
