May 23, 2012 - The Food and Drug Administration is approving the
first drug to prevent HIV. The drug, Truvada was approved in
2004 to treat people already infected with HIV. The experts are
basing their decision on groundbreaking studies conducted among
gay men and heterosexual couples at high risk of becoming
infected with HIV. Those trials showed that Truvada cut the risk
of new infection by at least 44 percent in healthy gay and
bisexual men and by 73 percent in heterosexual couples in which
one partner had HIV but the other did not. Also, if high blood
pressure runs in your family, there is something you can do
about it. Moderate exercise, and better cardiovascular fitness
can significantly reduce your risk of having high blood
pressure. Researchers at the University of South Carolina
studied more than 6 thousand people, and those who were fit, had
a 34 percent lower risk of developing high blood pressure, even
if they had a parent who had the disease.
