Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Fighting HIV, biomedical and behavioral hand in hand

In the HIV/AIDS arena, the idea of “treatment as prevention” has been gaining strength. Multiple studies have shown that treatment with anti-retroviral drugs can dramatically reduce the likelihood that someone infected with HIV will be able to pass the virus to someone else.

However, a recent strategy document for HIV/AIDS prevention developed by a International Antiviral Society–USA panel, co-led by Rollins Global Health chair Carlos Del Rio, puts biomedical interventions hand in hand with psychosocial measures such as couples counseling and treatment for drug dependence.

Why? Because people everywhere can have trouble sticking to antiretroviral treatment, even if drugs are available. And couples counseling by itself is valuable.

A powerful example of how this plays out, and of the importance of couples counseling to the effectiveness of antiretroviral drugs in prevention, comes from a recent presentation from Emory epidemiologist Kristin Wall at the AIDS 2014 meeting in Australia. The website NAM Aidsmap had a helpful write-up of her presentation, which is available here. Thanks to co-author Susan Allen for alerting us to this.

CVCT (couples voluntary counseling and treatment) greatly enhanced the preventive effect of antiretroviral treatment, when compared to treatment without counselling, Wall’s analysis of a large cohort of couples in Zambia showed. 

Update: Allen points out that couples counseling by itself was effective in helping people avoid HIV, with a 75 percent reduction in incidence for couples where the HIV+ partner was not receiving antiviral therapy or with HIV negative couples.  Read more
