Study: Gay, Bisexual Men Who Know Their HIV Status Less Likely to Engage in Risky Sex
Gay and bisexual men who know their HIV status are far less likely to engage in unprotected sex, which in lessens the sexual risk both for them and for their partner, according to the U.S. Centers for Disease Control and Prevention's (CDC) latest Morbidity and Mortality Weekly Report. An analysis of HIV-positive men who have sex with men (MSM) in 20 U.S. cities found that about 33 percent of those who did not know their status engaged in unprotected sex with a partner, and also did not know the status of the partner; men who knew their status were 60 percent less likely to do so, for an overall rate of 13 percent. MSM account for about two-thirds of new HIV infections and about half of the 1.1 million people in the United States with HIV. "While we remain concerned about potentially increasing levels of sexual risk, it is encouraging to see that risk is substantially lower in those who know they have HIV," said CDC Director Tom Frieden, MD, MPH. "HIV testing remains one of our most powerful tools to reverse the epidemic. Everyone should know their HIV status." Read more on HIV/AIDS.
Improved HealthCare.gov Faces Next Challenges
HealthCare.gov, the online portal for the Affordable Care Act, faces another test starting today as the Obama administration announced it met a weekend deadline to make the site easier to use and more accessible for most users. The original launch of the site was met with must frustration across the county as many people were unable to navigate the site properly or even to log in. The administration now expects a rush of people--both a backlog and people who have yet to try the site--to enroll by the December 23 deadline for coverage that would begin January 1. Multiple organizations, including Enroll America and AIDS Alabama, have announced plans to help people enroll. Jeffrey Zients, an administration advisor, warned that the post-Thanksgiving wave of enrollment could still overwhelm the servers at times. Read more on the Affordable Care Act.
Study: Energy Drinks Can Increase Strain on Heart
People who consume energy drinks can experience rapid heart contractions and increased strain on the heart up to an hour later, according to new research to be presented today at the annual meeting of the Radiological Society of North America, in Chicago. The findings raise concerns over the effects of caffeine and taurine on heart health, especially for people who already suffer from heart disease. Researchers used magnetic resonance imaging to measure the heart function of 18 health people both before and after they consumed an energy drink, finding an average 6 percent increase in the heart contraction rate afterward. "We know there are drugs that can improve the function of the heart, but in the long term they have a detrimental effect on the heart," said Williams, a cardiology professor at Wayne State University School of Medicine, in Detroit. Researchers noted that further study is needed to determine the reason for the apparent link. Read more on heart health.
