Offering option of initial HIV care at home increases use of antiretroviral therapy

LSTM Researchers found that offering adults in Malawi optional home initiation of care following HIV self-testing resulted in a significant increase in the proportion of adults initiating antiretroviral therapy (ART) compared with standard HIV care. The results are part of a study that was funded by the Wellcome Trust and published in the July 23/30 issue of JAMA , which is HIV/AIDS themed and released early to coincide with the International AIDS Conference taking place in Melbourne, Australia next week.

New trigger for ovulation could make IVF safer

New trigger for ovulation could make IVF safer

Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature. Doctors normally administer another hormone, hCG, for this purpose, but in some women, there is a risk that this can overstimulate the ovaries, with potentially life-threatening consequences.
