Effectiveness of HIV Prevention Method Varies in Women

A new study by scientists at the Centre for the AIDS Programme in Research in South Africa (CAPRISA), published in Nature Medicine this week, shows that genital inflammation significantly reduces the effectiveness of tenofovir gel in preventing HIV infection in women. These findings indicate that both genital inflammation and adherence need to be addressed to improve the effectiveness of topical pre-exposure prophylaxis strategies for HIV prevention in women.

Saline in Intravenous Fluid, more Concerns Raised

A new set of studies has explored the saline used in intravenous fluids in hospitals and found that they may not be as safe as earlier believed. These two large studies have found that the presently used concentration of saline leads to an increased risk of kidney damage and death and replacing them with an alternate fluid could reduce the deaths by 50,000 to 70,000 and reduce the number of kidney failures by 100,000 annually in the U.S.

Calcium Supplements Doubles The Risk For Polyps

In this study, researchers assumed that calcium supplementation might reduce the development of precancerous colorectal polyps. It didn't. Calcium supplementation alone more than doubled the risk for serrated sessile adenomas or polyps (SSA/Ps), and when combined with vitamin D, it almost quadrupled the risk. The study has published online in Gut.
