Dissolvable fabric loaded with medicine might offer faster protection against HIV

Soon, protection from HIV infection could be as simple as inserting a medicated, disappearing fabric minutes before having sex.

University of Washington bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams.

New intervention reduces risky sex among bisexual African-American men

A culturally tailored HIV prevention program developed and tested by investigators at UCLA and the Charles R. Drew University of Medicine and Science has been shown to significantly reduce unprotected sex among bisexual black men.

The innovative approach, called Men of African American Legacy Empowering Self, or MAALES, is described in an article in the peer-reviewed journal AIDS. (more…)

Women and HIV: A story of racial and ethnic health disparities

The history of women with HIV/AIDS in the United States is really a story of racial and ethnic health disparities.

Overall, the rate of American women contracting the disease relative to men has climbed from 8 percent in the 1980s to 25 percent today. But most of this burden is in underserved communities: one in 32 African-American women will be diagnosed with HIV in their lifetime, as will one in 106 Latina women. Meanwhile, one in 526 Caucasian and Asian women will contract the virus. Death rates are also higher for African-American and Latina women, making it one of the leading causes of death for those groups. (more…)

Economics of Public Health: Study Finds Price for Reducing HIV Risk

With a goal to reduce HIV risk behaviors, researchers investigated whether gay men and male sex workers in Mexico City would participate in a conditional cash transfer program that encourages HIV prevention education and regular testing. A new study in the European Journal of Health Economics reports the price that would get more than 75-percent participation: $288 a year.

PROVIDENCE, R.I. [Brown University] — Studies have found that conditional cash transfer programs, in which governments pay citizens if they consistently practice societally beneficial behaviors, have improved pediatric health care and education in Mexico, increased HIV testing in Malawi, and reduced sexually transmitted infections in Tanzania. Public health researchers therefore investigated whether the idea could be applied to HIV risk behaviors among gay men and male sex workers in Mexico City. A new study reports not only that some members of those populations would change behavior for conditional cash payments, but the exact prices they would accept. (more…)

Engineered Immune Cells Resist Infection from Hiv and Could Ultimately Replace Drug Therapy

AUSTIN, Texas — Researchers at The University of Texas at Austin and the Stanford University School of Medicine have found a novel way to engineer key cells of the immune system so they remain resistant to infection from HIV, the virus that causes AIDS. (more…)

Electrically Spun Fabric Offers Dual Defense Against Pregnancy, HIV

The only way to protect against HIV and unintended pregnancy today is the condom. It’s an effective technology, but not appropriate or popular in all situations.

A University of Washington team has developed a versatile platform to simultaneously offer contraception and prevent HIV. Electrically spun cloth with nanometer-sized fibers can dissolve to release drugs, providing a platform for cheap, discrete and reversible protection. (more…)

Groundbreaking Research Paves Way for HIV Prevention Drug Approval

For the first time, the U.S. Food and Drug Administration is considering approving a drug that helps prevent someone from acquiring HIV. It’s called Truvada, and has been approved for use since 2004 to treat infected people.

Now it has been shown to protect healthy people who are exposed to HIV. The UW’s International Clinical Research Center, within the Department of Global Health, played a key role in examining the drug’s effectiveness for HIV prevention.

Researchers Connie Celum and Jared Baeten led a study, published this week in the New England Journal of Medicine, of pre-exposure prophylaxis among heterosexual couples in Kenya and Uganda. One partner had HIV (and was not yet eligible for HIV treatment) and the other partner did not have HIV. Uninfected partners were given either Truvada or Tenofovir (both antiretroviral drugs) or a placebo. (more…)

Clergy can fight HIV on faith-friendly terms

In the United States, where blacks bear a disproportionate burden of the HIV/AIDS epidemic, black religious institutions could help turn the tide. In a new study in PLoS ONE based on dozens of interviews and focus groups with 38 of Philadelphia’s most influential black clergy, physicians and public health researchers find that traditional barriers to preaching about HIV prevention could give way to faith-friendly messages about getting tested and staying on treatment.

PROVIDENCE, R.I. [Brown University] — The public health community has long struggled with how best to reduce HIV infection rates among black Americans, which is seven times that of whites. In a new paper in the journal PLoS ONE, a team of physicians and public health researchers report that African-American clergy say they are ready to join the fight against the disease by focusing on HIV testing, treatment, and social justice, a strategy that is compatible with religious teaching.
