A once-a-day pill has been proven to lower the risk of getting HIV among needle-using drug addicts, just as it does among heterosexual couples and men who have sex with men.
Among 2,400 injecting drug users in Bangkok, those assigned to take a daily dose of an antiviral drug Viread, or tenofovir generically, had half the risk of getting HIV over a four-year period as those who took a placebo pill. Among those who took tenofovir faithfully, there were 74 percent fewer infections.
On Wednesday, the Urban Institute released a new report that revisits a famous study conducted almost 50 years ago by the late Sen. Daniel Patrick Moynihan. The original study, "The Negro Family: The Case for National Action," was written by Moynihan when he was an assistant secretary at the U.S. Department of Labor. In the report, Moynihan listed a series of ills he argued had helped cause poverty in black America.
Finding the right treatment for depression can be a struggle. People find relief with the first treatment only 40 percent of the time. Trying different antidepressants or therapies can take months, which means months of suffering.
Scientists are trying to better the odds by searching for signals in the body or in behavior that could be signposts to the right treatment. Researchers at Emory University say that PET scans of the brain may help predict which people do better on SSRI antidepressants, and which would benefit most from cognitive behavioral therapy instead.
