Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

HIV discordant couples

On Thursday, NPR had a nicely done story on discordant couples (one partner is HIV positive, the other is HIV negative) in Kenya.

It provided a reminder of Susan Allen’s work in Rwanda and Zambia with discordant couples. It also very simply laid out the policy issues connected with treating discordant couples:

Medical workers are http://www.raybani.com/ extremely interested in discordant couples for two reasons. One is that almost half of new infections in Kenya happen in these relationships. It’s one place where HIV is spreading. The second reason is that when couples are open with each other about their HIV status, managing HIV is more successful…

The World Health Organization now recommends that any HIV-positive individual in a discordant relationship be supplied HIV treatment. But discordant couples are still being treated on an ad hoc basis in Kenya, primarily because the funding for the medication just isn’t there.

Allen’s research provided critical data about HIV Ray Ban outlet transmission and prevention methods, and led to the adoption of the WHO guidelines mentioned in the story. She has said that the WHO guidelines were designed to help partners in a stable relationship work together to prevent the uninfected person from getting the virus and that low-tech, inexpensive prevention methods like condoms are just as important as antiretroviral therapy in this effort.

A storied look at HIV/AIDS in Africa

At a recent Emory global health seminar series, Kate Winskell showed how fiction penned by young Africans can help inform the response to HIV and AIDS. Since 1997, more than 145,000 young Africans have participated in scriptwriting contests as part of Scenarios from Africa HIV communication process.

The resulting archive of stories is a unique source of cross-cultural and longitudinal data on social representations of HIV and AIDS. The archive now spans 47 countries and a critical 12-year period in the history of the epidemic. Winskell’s presentation analyzed the stories that were part of the 2005 Scenarios contest. Six African countries were represented.

The seed for Scenarios was planted more than a decade ago–before the rise of the Internet—when Winskell, a public health educator, and her husband, Daniel Enger, were searching for innovative ways to reduce the spread of HIV/AIDS. The old ways of trying to stop the spread of the disease, focusing only on medical aspects of the epidemic or relying on educational materials that were not culturally adapted, were clearly limited.

Curiosity about health and a borderless world

Developing effective HIV prevention and intervention programs in the most affected communities is a challenge globally as well as locally. It’s also a challenge that Emory infectious disease specialist Carlos del Rio, MD, is addressing as newly appointed chair of the Rollins School of Public Health’s Hubert Department of Global Health.

Carlos del Rio, MD

Del Rio is uniquely equipped to address HIV prevention and intervention. As the former chief of medicine at Grady Memorial Hospital, Atlanta’s safety-net hospital, he witnessed firsthand patients affected by the disease. He says there ought to be incentives for people to stay healthy instead of barriers to staying healthy.

More daunting for del Rio is preventing disease on a global scale, much of which rests on changing unhealthy behaviors related to diet, exercise, smoking, and sex. He says we know very little about how to implement population-wide behavior change, and we need to learn more.

Del Rio says growing human capital to strengthen research capacity in resource-constrained countries is also key. Since 1998, the NIH/Fogarty International Center has funded the Emory AIDS Training and Research Program (AITRP) to build capacity in Armenia, the Republic of Georgia, Ethiopia, Mexico, Rwanda, Vietnam and Zambia. Led by del Rio, AITRP brings a select group of young scientists to Emory each year for advanced training. Emory faculty also train and mentor scientists in these countries.

The training program has opened avenues to improving health. In Ethiopia, del Rio helped expand HIV testing among the police force and bring antiretroviral therapy into the community for people living with HIV.

In the Republic of Georgia, the Emory AITRP and the Emory-Georgia Tuberculosis Research Training Program, another NIH/Fogarty program led by RSPH adjunct faculty member and Emory School of Medicine professor  Henry Blumberg, MD, has helped build research capacity in HIV, hepatitis, and tuberculosis research.
