One of the unsolved mysteries about COVID-19 is why it has a lesser impact on children, even kids with asthma. University of Arizona pediatric researcher Fernando Martinez, director of the Asthma and Airway Disease Research Center, says children in general are at lower risk for COVID-19, but why the disease does not affect those with asthma is especially interesting.

Roberta Diaz Brinton, PhD, at the University of Arizona Center for Innovation in Brain Science, is researching Type 2 diabetes therapies and associated risks of Alzheimer’s in women. The funding for her study is a $500,000 grant from the Women's Alzheimer's Movement.

The COVID-19 pandemic has seen an increase of digital healthcare, especially by older adults. The Arizona Telemedicine Program founded by Ronald S.

When it comes to sleep, need and ability are two different things. “It’s pretty clear that sleep ability decreases with age,” says Michael Grandner, director of the Sleep and Health Research Center at the University of Arizona College of Medicine – Tucson.

The significant role and impact of structural racism needs to be considered in racial and ethnic health-disparities research, say the editors of the American Heart Association journal Circulation: Cardiovascular Quality and Outcomes. Khadijah K. Breathett, MD, assistant professor in the Division of Cardiology at the University of Arizona College of Medicine – Tucson and associate editor of the journal, co-authored the statement.

The past two flu seasons were the worst the state has ever seen, but this season has seen a 93% decrease in the number of cases and is one of the lowest on record – all likely due to COVID-19. "It's a dominant organism in the community.
