Do men who have sex with men underestimate their HIV risk and miss out on preventive PrEP?

2014-06-23
(Press-News.org) New Rochelle, NY, June 23, 2014—Men who have sex with men (MSM) have a disproportionately high risk of acquiring HIV, and unprotected sex between men accounts for most new HIV diagnoses in the U.S. Yet this population tends to underestimate their HIV risk and not take advantage of effective options such as pre-exposure prophylaxis drug treatment to prevent HIV infection, as documented in an article published in LGBT Health, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the LGBT Health website.

Demetre Daskalakis, MD, MPH, Icahn School of Medicine at Mt. Sinai (New York, NY), Timothy Gallagher, New York University School of Medicine and Bellevue Hospital Center, and coauthors evaluated a group of MSM being tested for HIV to determine their HIV risk and whether they would be candidates for PrEP, based on demographic factors, sexual activity, and drug use during the previous three months. The authors also asked the men questions to assess how they perceived their own risk for HIV infection. The large discrepancy between actual risk and perception of risk among MSM is described in the article "Self-Perception of HIV Risk and Candidacy for Pre-Exposure Prophylaxis Among Men Who Have Sex with Men Testing for HIV at Commercial Sex Venues in New York City."

"For those MSM most at risk of HIV infection, adherence to a daily regimen of PrEP and use of condoms can potentially slow the forward transmission of HIV to the point that the epidemic cannot be maintained in regions where it is propelled by new infections among MSM," says Editor-in-Chief William Byne, MD, PhD, Icahn School of Medicine at Mount Sinai, New York, NY. "For this to occur, both MSM and their providers must be more knowledgeable about PrEP and assessment of HIV risk. Importantly, the U.S. Public Health Service just this month issued a clinical practice guideline on PrEP that addresses indications for use and assessment of HIV risk."

Diabetes drug, Liraglutide, improves risk factors for heart disease

2014-06-23
CHICAGO, IL — Treatment with the diabetes drug liraglutide, in combination with diet and exercise, led to a significant reduction in weight and improved a number of cardiovascular risk factors, including high blood pressure and high cholesterol, according to a multicenter study. The results, from more than 3,700 overweight and obese nondiabetic adults, were presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. "If these improvements continue over time, they may result in a lower risk ...

BUSM researchers investigating ways to improve type 2 diabetes treatments

2014-06-23
(Boston) – A better understanding of how the transcription factor Peroxisome Proliferator-Activated Receptor Gamma (PPARgamma) works is critical to find new ways to improve medications to treat type 2 diabetes. Drugs that activate PPARgamma, called thiazolidinediones (TZDs), have long been regarded as a treatment for type 2 diabetes based on their anti-inflammatory and potent insulin-sensitizing activity. When taken orally, TZDs help decrease insulin resistance. However, most medications in that class have now been withdrawn from the market, or severely limited in their ...

Long non-coding RNAs can encode proteins after all

2014-06-23
Case Western Reserve School of Medicine scientists have made an extraordinary double discovery. First, they have identified thousands of novel long non-coding ribonucleic acid (lncRNA) transcripts. Second, they have learned that some of them defy conventional wisdom regarding lncRNA transcripts, because they actually do direct the synthesis of proteins in cells. Both of the breakthroughs are detailed in the June 12 issue of Cell Reports. Kristian E. Baker, PhD, assistant professor in the Center for RNA Molecular Biology, led the team that applied high throughput gene ...

Exposure to BPA substitute causes hyperactivity and brain changes in fish

2014-06-23
CHICAGO, IL — A chemical found in many "BPA free" consumer products, known as bisphenol S (BPS), is just as potent as bisphenol A (BPA) in altering brain development and causing hyperactive behavior, an animal study finds. The results will be presented Sunday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. BPA has been linked to a wide range of hormone disorders, such as obesity, reproductive cancers and, recently, hyperactivity in children born to women exposed to high levels of this substance during ...

BPA stimulates growth of breast cancer cells, diminishes effect of treatment

2014-06-23
DURHAM, N.C. – Bisphenol A (BPA), a chemical commonly used in plastics, appears to increase the proliferation of breast cancer cells, according to Duke Medicine researchers presenting at an annual meeting of endocrine scientists. The researchers found that the chemical, at levels typically found in human blood, could also affect growth of an aggressive hormone-independent subtype of breast cancer cells called inflammatory breast cancer and diminish the effectiveness of treatments for the disease. "We set out to determine whether routine exposures to common chemicals ...

Hormone-disrupting activity of fracking chemicals worse than initially found

2014-06-23
CHICAGO, IL—Many chemicals used in hydraulic fracturing, or fracking, can disrupt not only the human body's reproductive hormones but also the glucocorticoid and thyroid hormone receptors, which are necessary to maintain good health, a new study finds. The results were presented Monday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. "Among the chemicals that the fracking industry has reported using most often, all 24 that we have tested block the activity of one or more important hormone receptors," ...

Common BPA-like chemical, BPS, disrupts heart rhythms in females

2014-06-23
CHICAGO, IL—Bisphenol S (BPS), a common substitute for bisphenol A (BPA) in consumer products, may have similar toxic effects on the heart as previously reported for BPA, a new study finds. The results were presented Monday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. In the years since research evidence first showed many potentially damaging health effects of the industrial chemical BPA, some manufacturers have switched to its chemical cousin, BPS, to make hard plastics and other products that ...

Electrostatics do the trick

Electrostatics do the trick
2014-06-23
Organic semiconductors allow for flexible displays (OLEDs), solar cells (OPVCs), and other interesting applications. One common problem in these devices, however, is the interface between the metallic contacts and the organic semiconductor material, where undesirable losses occur. Now Dr. Martin Oehzelt has shown what these losses between the metal and the organic semiconductors depend upon and how to minimize them. In particular, his model also explains why a thin, electrically insulating layer between the two materials can even facilitate the transition of charge carriers. ...
