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

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Heart Month: Helping narrowed aortic valves

Celebrating February’s American Heart Month at Emory Heart & Vascular Center

Emory cardiologists are using a promising new non-surgical treatment option for patients with severe aortic stenosis.

Emory University Hospital is one of about 20 hospitals nationwide, and the only site in Georgia, to study this new technology – with 75 patients receiving new valves at Emory since the clinical trial started in October 2007. Researchers hope to receive U.S. Food and Drug Administration approval in late 2011.

The life threatening heart condition affects tens of thousands of Americans each year when the aortic valve tightens or narrows, preventing blood from flowing through normally.

Peter Block, MD

Peter Block, MD, professor of medicine, Emory School of Medicine, and colleagues are performing percutaneous aortic valve replacement as part of a Phase II clinical trial, comparing this procedure with traditional, open-heart surgery or medical therapy in high-risk patients with aortic stenosis.

The procedure provides a new way for doctors to treat patients who are too ill or frail to endure the traditional surgical approach.

During the procedure, doctors create a small incision in the groin or chest wall and then feed the new valve, mounted on a wire mesh on a catheter, and place it where the new valve is needed.

Emory Heart & Vascular Center advances medicine

American Heart Month 2010

Learn about Emory Heart & Vascular Center advances during American Heart Month.

Research led by John Puskas, MD, professor of surgery and associate chief, Division of Cardiothoracic Surgery, Emory School of Medicine, has shown that off-pump bypass surgery reduces the risk of complications for high-risk patients, such as those that are especially frail or those with diabetes, obesity, kidney disease or a history of stroke.

This conclusion comes from a 10-year history of coronary bypass patients at Emory recently published in the Annals of Thoracic Surgery.

Puskas also recently presented long-term follow-up data from the first randomized U.S. trial to compare off-pump with conventional on-pump surgery.

The results from the landmark SMART (Surgical Management of Arterial Revascularization) study, which started in 2000, show that participants who had the off-pump procedure lost less blood, had less damage to their hearts during surgery and recovered more quickly than those who underwent on-pump surgery.

Beating-heart patients in the study also were able to breathe on their own sooner after surgery, spent less time in intensive care and left the hospital one day sooner, on average, than conventional coronary bypass patients.
