FDA to Approve Drug for HIV Prevention
An expert committee has recommended that a drug trade-named Truvada be offered daily to gay men and people living with infected partners to prevent them from catching HIV.
What's the Latest Development?
An expert committee at the Food and Drug Administration has recommended that an antiviral drug trade-named Truvada be offered daily to uninfected people to prevent them from catching HIV. The drug, which combines two antiviral drugs called tenofovir and emtricitabine, is currently available only to those who have already contracted the virus. The first beneficiaries of the drug's extended license are likely to be homosexual men and uninfected partners in relationships where one of the pair already has the virus. "The FDA will make a final decision on whether to approve Truvada for 'pre-exposure prophylaxis' by 15 June."
What's the Big Idea?
While we do not yet have a vaccine against HIV, the approval of Truvada for preventative use may be the next best thing. In a 2010 study, homosexual men who took Truvada reduced their risk of HIV contraction by 44%. In another study completed in Kenya and Uganda, researchers wanted to know if the drug could stop the virus from spreading in couples where one partner carried the disease but the other did not. "It found that Truvada given to the uninfected partner reduced their risk of infection by 73 per cent." The drug should act in concert with other preventative measures, including condoms, safe sex and male circumcision.

We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
