Your daily dose of omega-3s may not be doing what you think it is. Most fish oil supplements on the market today have labels boasting health benefits that aren’t supported by clinical data, according to a study published in JAMA Cardiology by researchers at UT Southwestern Medical Center.

Being younger doesn’t protect against the dangers of COVID-19 if you are overweight, according to a new study from UT Southwestern.

A UT Southwestern research team has catalogued gene activity in the skeletal muscle of mice, comparing healthy animals to those carrying a genetic mutation that causes Duchene muscular dystrophy (DMD) in humans.

A team led by UT Southwestern researchers has identified a key gene necessary for cells to consume and destroy viruses. The findings, reported online today in Nature, could lead to ways to manipulate this process to improve the immune system’s ability to combat viral infections, such as those fueling the ongoing COVID-19 pandemic.

Despite the high number of confirmed cases, the true prevalence of COVID-19 infections is believed to be underestimated due to insufficient testing capacity and a high percentage of asymptomatic people.

A once-daily combination treatment for those with uncontrolled Type 2 diabetes amplifies the treatment’s effects – lowering both weight and the number of hypoglycemic events, and improving quality of life and glucose control ¬– and makes participants more likely to adhere to their medications.

Researchers at UT Southwestern have uncovered evidence that the higher prevalence of “malignant” enlargement of the heart among blacks contributes to the higher incidence of heart failure in this population.

While Black and Hispanic families are enthusiastic about research participation, other provider and systems-focused factors may influence their involvement in pediatric oncology clinical trials, a new UT Southwestern Medical Center-led study has found.

Interpreting relatively inexpensive electrocardiograms (ECGs) with an artificial intelligence (AI) algorithm accurately screened patients for a key precursor of heart failure in Kenya, a study led by UT Southwestern Medical Center researchers shows.

A team co-led by UT Southwestern Medical Center researchers has identified cellular and molecular mechanisms that could explain the effects of deep brain stimulation (DBS).
