Treatment drugs can do more than improve the health of people with HIV: If administered early, medications can also reduce the spread of the disease to sexual partners and may help stem the AIDS epidemic. But many logistical hurdles stand in the way of making this strategy feasible, affordable and effective, according to experts writing in Tuesday's edition of the journal PLoS Medicine. The medications in question are antiretroviral therapies, which prevent HIV from multiplying and drastically diminish the amount of virus circulating in the blood.

Are people who suffer from mental illnesses more likely to commit violent crimes? That question has been on the nation's mind since a 22-year-old community college dropout with a history of odd behavior was charged with shooting 19 people outside a Tucson supermarket this month, killing six and wounding Rep. Gabrielle Giffords (D-Ariz.), who police say was his target. The answer may seem obvious to the general public, given the popularity of movies, TV shows and books in which mentally unbalanced individuals are portrayed as homicidal maniacs.

The 2009 H1N1 "swine flu" epidemic killed up to 203,000 people across the globe -- a death toll 10 times greater than initially estimated by the World Health Organization, researchers say. In a study published Tuesday in the journal Plos Medicine, epidemiologists used data on respiratory deaths in 20 nations to calculate a global mortality rate for the pandemic. Prior to this research, the WHO counted just 18,631 lab-confirmed cases of H1N1, a viral infection of the airways.

Researchers have discovered a gene mutation that protects people in Southeast Asia against malaria in much the same fashion that a sickle cell trait protects Africans from the disease. But while the sickle cell protects against the frequently lethal form of the disease caused by the parasite Plasmodium falciparum , the newly discovered gene mutation protects against Plasmodium vivax , which is generally thought to be more benign. Malaria causes an estimated 1 million deaths per year worldwide, and at least half the world's population lives in areas at risk for the disease.

Multinational food corporations have a growing influence on the health of people around the world, including obesity, and their actions need greater scrutiny, according to an editorial Tuesday in the journal Public Library of Science Medicine. The editorial kicks off the journal's three-week series looking at what it calls “Big Food.” The first articles, and the editorial, criticize not just the food companies but also officials charged with protecting public health. “The big multinational food companies control what people everywhere eat, resulting in a stark and sick irony: one billion people on the planet are hungry while 2 billion are obese or overweight,” the editorial says.

With $3 billion in new pledges, world leaders say they believe that an ambitious goal to stop deaths from malaria by 2015 is finally within reach. A plan billed as the most comprehensive ever to tackle the mosquito-borne disease, which kills nearly 1 million people each year, was unveiled last week at a United Nations gathering of heads of government, global health leaders and philanthropists.

Before embarking on a medically invasive, expensive and emotionally taxing effort to get pregnant through in vitro fertilization, it sure would be nice to get a good sense of whether it’s likely to work. After all, only about 1 in 4 attempts resulted in a live birth as recently as 2007. So researchers from England and Scotland scoured data from more than 144,000 IVF cycles in the United Kingdom and looked for factors that might predict which couples stood the best chance of having a baby with assisted reproduction and which faced long-shot odds.

The twin plagues of economic hardship and low academic attainment turn out to be an inflammatory problem, not just for society but for the human bodies beset by them. And for many, including those in minority groups who disproportionately experience stunted economic and academic prospects, high rates of Type 2 diabetes are the common result, a new study says. The new research, based on a long-running study of British government workers, offers a partial explanation for a trend that is firmly established in industrialized democracies -- that where calories are plentifully available, those clinging to the lower rungs of the economic ladder are most likely to develop Type 2 diabetes.

Want to gauge your risk for developing Type 2 diabetes? Don't just step on the scale - reach for a measuring tape too, a new study suggests. The circumference of your waist can tell you a lot about your chances of getting diabetes, according to a study published Tuesday in the journal PLoS Medicine . Health providers usually rely on body mass index to determine patients' diabetes risk, but adding waist circumference to the equation would...

It will be an even 20 for Michelle and Jim Bob Duggar, who announced Tuesday that they're expecting their 20th child. The Duggars, stars of their own TLC show, are a source of fascination for some people, since super-sized families aren't the norm the way they were about a century ago. Michelle Duggar, you'll recall, didn't have such an easy time around with her last pregnancy in 2009. Daughter Josie was delivered early when it was discovered that Michelle had preeclampsia and gall bladder problems (Josie is now doing fine)
