Women are underrepresented in academic surgery, but women surgeons are earning a disproportionate share of research grants from the National Institutes of Health, a new study has found.
Pediatric cardiologists are offering important advice on if and when it is safe for children and teens to return to playing sports after recovering from COVID-19.
Disorganized efforts to implement artificial intelligence in hospitals could undermine the technology’s vast potential to benefit patients, the group warns.

The discovery of the oncogene responsible for glioblastoma could be the brain tumor’s Achilles’ heel, one researcher says.
Only 1.9% of uninfected household contacts who took a single dose of baloxavir marboxil came down with the flu.
The new discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called “microfibrils.”
Sweden’s controversial decision not to lock down during COVID-19 produced more deaths and greater healthcare demand than seen in countries with earlier, more stringent interventions, a new analysis finds.
Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests.
In addition to its predictive value, the discovery could lead to new treatments to prevent deadly cytokine storms. It also may help explain why diabetes contributes to worse outcomes in patients with COVID-19.
Invasive fire ants common in the Gulf Coast and Texas likely are limiting a tick-acquired meat allergy in these areas, scientists report. But they have a nasty bite of their own.
An innovative use of focused ultrasound is showing promise against glioblastoma, the deadliest brain tumor, and could prove useful against other difficult-to-treat cancers.
A collaborative program developed at UVA Health to work with local long-term care facilities to control COVID-19 is saving lives and offers a model for communities across the country, a new scientific paper reports.
A top exercise researcher is urging clinical trials of exercise in patients with Friedreich’s ataxia after finding that physical activity has a “profound” protective effect in mouse models of the debilitating genetic disease.
UVA Health has partnered with the Virginia Department of Health and other hospitals around the state to determine how many Virginians have been infected with COVID-19 – and how many remain at risk.
New research is shedding light on the biological architecture that lets us hear – and on a genetic disorder that causes both deafness and blindness.
The Integrated Translational Health Institute of Virginia (iTHRIV) has developed an online tool to collect COVID-19 information from volunteers who live in Virginia.
A new guide from emergency medicine doctors details the potentially deadly cardiovascular complications COVID-19 can cause.

Two top scientists are seeking answers to questions about spinal cord injuries that have long frustrated the development of effective treatments.
Improper removal of faulty brain cells during neurodevelopment may cause lifelong behavioral issues, new research from the University of Virginia School of Medicine suggests. The finding also could have important implications for a wide range of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.
By mining a vast trove of genetic data,researchers at the University of Virginia School of Medicine are enhancing doctors’ ability to treat cancer, predict patient outcomes and determine which treatments will work best for individual patients. The researchers have identified inherited variations in our genes that affect how well a patient will do after diagnosis and during treatment.
Though COVID-19 so far appears to be largely sparing children, researchers are cautioning that it is critical to understand how the virus affects kids to model the pandemic accurately, limit the disease’s spread and ensure the youngest patients get the care they need.
The researchers have already confirmed their discovery in human tissue samples and used it to reverse high blood pressure in lab mice.
A new guide seeks to ensure healthcare providers are ready to help new mothers with the challenging first week of breastfeeding – and to address gaps in knowledge and support created in previous decades when breastfeeding was far less common.
“Under-representation of Asian populations in genetic studies has meant that medical relevance for more than half of the human population is reduced,” one researcher said.
It would be the first treatment for “dry” age-related macular degeneration and could significantly improve treatment for wet AMD.
