Beth Malow, MD, professor of Neurology and Pediatrics, was quoted by The Washington Post in a story about melatonin doses can differ from the information on the label. An FDA study of 110 melatonin supplements marketed for children found doses ranged from 0 to 667 percent of the amount on the label.

William Schaffner, MD, professor of Preventive Medicine, was quoted by several news outlets about public health issues, including The Washington Times in a story about fewer adults being inclined to test for COVID; an Associated Press piece with interviews from families of people who died from vaccine-preventable diseases (Key quote: “If you’re not familiar with the disease, you don’t respect or even fear it. And therefore you don’t value the vaccine”); as well as ABC News and NBC News stories based on the same reporting from the AP. Schaffner also spoke to FactCheck.org about the effectiveness of giving hepatitis B vaccines to newborns — a practice that has been very effective at preventing disease, but which some federal officials are now questioning.

Heather Burrell Ward, MD, assistant professor of Psychiatry and Behavioral Sciences, was quoted in a HealthDay story about the research that she and Alexandra Moussa-Tooks, MD, published about how grip strength could provide a clue about psychosis; people with psychosis have weaker grip strength. VUMC News writer Danny Bonvissuto’s report on the research is here.

Stacie Dusetzina, PhD, professor of Health Policy, was quoted by The Washington Post in a story headlined, “A Texas boy needed protection from measles. The vaccine cost $1,400.”

Angela Jefferson, PhD, professor of Neurology and Medicine, was quoted in a HealthDay story about the relationship between living in a poor neighborhood and an increased risk for dementia.

Healio carried a report, “Navigational bronchoscopy similar to CT-guided biopsy in lung nodule diagnostic accuracy,” that quotes Fabien Maldonado, MD, MSc, professor of Medicine.
