Study also confirms condom use significantly reduces risk of HIV infection The level of HIV-1 in the blood of an HIV-infected partner is the single most important factor influencing risk of sexual transmission to an uninfected partner, according to a multinational study of heterosexual couples in sub-Saharan Africa. The study, published in the Journal of Infectious Diseases, calculated the risk of HIV-1 transmission per act of sexual intercourse and found the average rate of infection to...
Researchers at Duke University Medical Center have developed a new way to identify the genes of harmful microbes, particularly those that have been difficult to study in the laboratory. This new method uses chemicals to create mutant bacteria, followed by genomic sequencing to identify all mutations. By looking for common genes that were mutated in Chlamydia sharing a particular trait, the investigators were able to rapidly "zero in" on the genes responsible for that trait. The approach...
An investigational vaccine protected some women against infection from one of the two types of herpes simplex viruses that cause genital herpes, according to findings in the New England Journal of Medicine. The vaccine was partially effective at preventing herpes simplex virus type 1 (HSV-1), but did not protect women from herpes simplex virus type 2 (HSV-2). There were less than half of the cases of genital herpes caused by HSV-1 -- 58 percent fewer -- in women who received the...
In this week's PLoS Medicine, Johannes Bogaards of VU University, the Netherlands and colleagues use mathematical models to investigate whether vaccinating females only, males only, or both sexes is the best way to achieve the most effective reduction in the population prevalence of sexually-transmitted infections. Specifically for human papillomavirus (HPV), the authors found that single-sex vaccination was the most effective strategy for prevention of disease and that it was preferable to...
(Ivanhoe Newswire) – Investigators at Johns Hopkins Children’s Center shed light on the need for greater recognition of the sexual and reproductive healthcare needs of teen boys, and show how essential these services are annually for this normally overlooked group. The first report underscores what experts say is glaring absence of guidelines on what sexual health tests and screening procedures teenage males should get and how often. The article offers a list of clinical practice...
More evidence emerges to support that the progenitor of syphilis came from the New World Skeletons don't lie. But sometimes they may mislead, as in the case of bones that reputedly showed evidence of syphilis in Europe and other parts of the Old World before Christopher Columbus made his historic voyage in 1492. None of this skeletal evidence, including 54 published reports, holds up when subjected to standardized analyses for both diagnosis and dating, according to an appraisal in the...
Behavioral interventions aimed at reducing sexual risk behaviors, such as unprotected sex, are effective at both promoting condom use and reducing sexually transmitted infections (STIs) long after the initial intervention, according to a new report in the December 15 issue of the Journal of Acquired Immune Deficiency Syndromes. Lead author Lori A. J. Scott-Sheldon, Ph.D., of The Miriam Hospital's Centers for Behavioral and Preventive Medicine, and colleagues at the University of...
HealthForumOnline (HFO), a provider of continuing education (CE/CEU) courses for psychologists, social workers, counselors, and nurses, announces a new online course entitled Promoting Sexual Health Among Young Adults: Getting Past the Stigmas of Sexually Transmitted Infections (STIs). Sexual health remains a sensitive and relatively taboo topic, for both patients and health professionals. Social stigmas and misinformation perpetuate a climate of confusion and anxiety which impede the...

PITMAN, N.J., Dec. 13, 2011 /PRNewswire/ -- And another sexual myth is busted: Not only are more people over 50 having sex, but more of these individuals are getting the sexually transmitted diseases (STDs) to prove it. According to an article in the November/December issue of the journal MEDSURG Nursing, rates of HIV/AIDS, herpes, syphilis, human papilloma virus (HPV), and other STDs are climbing steadily in this age group. But the news gets worse: thanks to ageism and social...

Mycoplasma genitalium is a small parasitic bacterium that lives on the ciliated epithelial cells of the primate genital and respiratory tracts. It is the smallest known free-living bacterium. Up until 2002 it was also considered to be the organism with the smallest genome. M. genitalium was isolated in 1980 from urethral specimens of two male patients with non-gonococcal urethritis. Infection is fairly common and can be transmitted between partners during unprotected sex. It can be treated...
