Changing the way we think about food, not just as fuel but to fight illness and disease, is the focus of a growing culinary medicine program at the University of Arizona, where doctors are being trained to prescribe the right meals as medicine. "Food really is medicine and good food can really heal us, treat, prevent and reverse the diseases of our time," says Farshad Fani Marvasti, MD, MPH, associate professor and director of Public Health, Prevention and Health Promotion Curriculum at the College of Medicine – Phoenix.

COVID-19 has added another health hazard for older adults. Once infected with the virus, people in their 60s, 70s, 80s and above are at increasingly higher risk of experiencing severe COVID-19 illness, hospitalization and death. Although its difficult to precisely measure the impact of immune-system aging, "We know that it adds a massive risk. Those over 80 are 260-fold more likely to die from COVID-19 than those between 18 and 39," says Janko Nikolich-Žugich, MD, PhD, department head and professor of immunobiology at the College of Medicine – Tucson.

Allan J. Hamilton, MD, a professor of neurosurgery at the College of Medicine – Tucson, discusses how the human brain handles stress and the relationship between workplace design and employee well-being. "We get thrown into imbalance, and when we lose that connection with nature, we become perpetually anxious and stressed. Being more inclusive, more diverse and looking at group identity tends to end up being a better equation both for architecture and for the peace of mind of the human brain," Dr. Hamilton said.

A new study suggests that state laws requiring "universal" motorcycle helmet use – instead of helmet laws just for certain ages – may lower the rates of traumatic brain injuries in young riders. Traumatic brain injuries are "the biggest burden in trauma care, so we wanted to see whether having universal helmet laws versus age-specific helmet laws really made a difference in the younger population," said study co-author Bellal Joseph, MD, a trauma surgeon and associate professor of surgery at the College of Medicine – Tucson.

A proposed joint venture between Yuma Regional Medical Center and hospital management company LifePoint Health, a holding of the private equity firm Apollo Management Group, would change the hospitals' not-for-profit status to a for-profit model. Daniel Derksen, MD, professor of public health at the Mel and Enid Zuckerman College of Public Health and director of the UArizona Center for Rural Health, discusses various hospital ownership and management models, including the fairly recent introduction of private equity firms into the ownership landscape.

Vaccination against COVID-19 provides stronger protection than immunity from a previous infection with the coronavirus, according to a study from the Centers for Disease Control and Prevention published Friday. Deepta Bhattacharya, PhD, a professor of immunobiology at the College of Medicine – Tucson, cautioned that it can be very difficult to compare vaccine-induced immunity to infection-induced immunity. “What I would say is that these are maybe not the right terms of the debate,” he said. “The reason to prefer vaccine-induced immunity is that infections can make you really sick, not that they don’t leave you immune,” Dr. Bhattacharya said.

As border reopening nears, a $2.5 million grant and new HQ for the Ventanilla de Salud program are announced to support expected increase in visitors.

Psychologists and sleep doctors who study dreaming aren’t surprised if the hit Netflix series Squid Game is seeping into your non-waking hours. When you watch something that resonates with you, it’s going to stick with you, particularly if you watched a lot of the show in a short amount of time – and particularly if you’ve done so just before bed, says Michael Grandner, PhD, an associate professor and director of the sleep and health research program at the College of Medicine – Tucson. Dr. Grandner and other dream experts discuss why we dream and, more specifically, why we have nightmares.

Geoffrey Gurtner, MD, will join the College of Medicine – Tucson in January 2022 as head of the Department of Surgery.
