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

Detecting Lung Cancer at a Higher Rate

The findings from a recent study show the risk of dying from lung cancer could be reduced by 20 percent by use of a low-dose helical computed tomography (CT) scan.  With 160,000 deaths each year related to cigarette smoking, this type of screening could save up to 32,000 lives each year.

The National Cancer Institute (NCI) launched the multicenter National Lung Screening Trial (NLST) in 2002,  led at Emory by radiologist and researcher Dr. Kay Vydareny.  This trial compared two ways of detecting lung cancer: low-dose helical (spiral) computed tomography (CT) and standard chest X-ray, for their effects on lung cancer death rates in a high-risk population.

Both chest X-rays and helical CT scans have been used as a means to find lung cancer early, but the effects of these screening techniques on lung cancer mortality rates had not been determined. Over a 20-month period, more than 53,000 current or former heavy smokers ages 55 to 74 joined NLST at 33 study sites across the United States. In November 2010, the initial findings from NLST were released. Participants who received low-dose helical CT scans had a 20 percent lower risk of dying from lung cancer than participants who received standard chest X-rays.
