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.

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…)

A study by researchers at the UCLA Stroke Center found that stroke and cardiovascular disease have exacted an enormous toll on Hollywood stars.

The findings were presented at the American Heart Association/American Stroke Association’s International Stroke Conference (ISC) in Los Angeles on Feb. 10.

“Since this is the first time the ISC is being held in Los Angeles, we thought it was an appropriate occasion to investigate the frequency and impact of stroke among leading Hollywood actors,” said Hannah Smith, a staff research associate at the UCLA Stroke Center. “By documenting the toll that stroke and myocardial infarction have exacted on stars like Kirk Douglas and Grace Kelly, we hope to illustrate the damage that cardiovascular disease can cause.” (more…)

GAINESVILLE, Fla. — Thousands of women receive unnecessary surgical breast biopsies in Florida each year, University of Florida researchers state in an article published online this week by the American Journal of Surgery.

These surgeries carry greater health risks and are more expensive than a less invasive, equally effective procedure called a needle biopsy. (more…)
