August 1, 2012 - Timothy Brown sounds like a pretty common name, so it might not mean much to you but this particular Tim Brown is allegedly the only person ever cured of the HIV infection. Brown, also known as "the Berlin Patient", was HIV positive and fighting leukemia in 2007. Doctors in Germany wiped out his immune system with chemotherapy and radiation. Then, they gave him two rounds of stem-cell transplants. German researchers say the donor had a rare, inherited gene mutation that makes stem cells naturally resistant to infection with HIV. Scientists are hesitant to call this a cure for HIV. They say Brown's situation was not typical, and treatment like his is not a practical option for most patients.
Also, a new study finds anxiety disorders among poor mothers are more likely the result of their difficult economic situation, rather than mental illness. Previous studies have shown that mothers living in poverty are at higher risk of having generalized anxiety disorders, but those studies did not look at environmental factors. Researchers say in many cases, the best way to help those mothers may be with financial aid, rather than therapy.
