Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Looking at simple foods to protect against breast cancer

Researchers at the Winship Cancer Institute of Emory University have found that the hormone adiponectin may reduce the ability of cancer cells to migrate from the breast and invade other tissues. Adiponectin appears to protect against the effects of obesity on metabolism, the heart and blood vessels, the researchers say.

Fat cells make up most of the breast tissue, and some of the hormones produced by fat cells can have tumor-stimulating effects. Previous studies have shown that women with high body mass index (highest fifth) have double the death rate from breast cancer compared to those in the lowest fifth.

The key to translating this research for patient care lies in finding a way to increase a person’s adiponectin, says Dipali Sharma, PhD, assistant professor of hematology and medical oncology at Winship.

Currently, Winship scientists are testing a molecule found in certain foods that appears to mimic the effects of adiponectin. The molecule is found in grapes, cabbage and green tea.
