Researchers are expanding research showing that creating good sleeping habits can help people quit smoking to focus on smokers who are HIV positive.

An early interest in how the mind works led Dr. Rastogi to specialize in pediatric headaches, a widespread and under-studied health problem.

More studies will be required to back up the not-yet-peer-reviewed findings, but it's not "unreasonable to think that these immune memory components would last for years," Deepta Bhattacharya, an immunologist at the University of Arizona told the New York Times. It may also be another layer of good news on the vaccine front, since vaccinations typically provide better, longer-lasting protection than natural infections. If that holds true in the case of COVID-19, people would theoretically get to avoid an annual booster shot. Bhattacharya was not involved in the study cited in this article.

The University of Arizona Health Sciences is launching Wellness Wednesdays: Celebrating Health & Holiday — a free, seven-week e-newsletter series beginning Nov. 18, designed to encourage participants and build a sense of community to increase health and decrease stress.

An opinion columnist writes that hospitals could reach capacity quickly as coronavirus cases surge in Arizona. The article cites the research of Joe Gerald, an associate professor with the University of Arizona's Mel and Enid Zuckerman College of Public Health.

Once a person develops immunity against COVID-19, it could last for years, a new study suggests. At the very least, exposure appears to at least set up the body for immunity “memory,’’ meaning its protective system should kick in and significantly fight off a second attack. “I don’t think it’s an unreasonable prediction to think that these immune memory components would last for years, said Immunologist Dr. Deepta Bhattacharya from the University of Arizona College of Medicine – Tucson who was not involved in the study.

Researchers found no significant difference for all-cause mortality or cardiopulmonary hospitalization among patients who received the high-dose influenza vaccine compared with those who received the lower dose. Dr. Martha Gulati, Division Chief of Cardiology at the University of Arizona College of Medicine – Phoenix, provides perspective on the study.

Arizona was in the bottom tier in three of six categories in a new American Lung Association report, which put the state dead-last for the number of patients who receive treatment after getting a diagnosis of lung cancer. Dr. Dan Derksen, associate vice president for Health Equity, Outreach & Interprofessional Activities at the University of Arizona Health Sciences, said racial and ethnic data jumped out to him because of Arizona's relatively large Hispanic and Native American populations. "Those populations are disproportionately affected for a number of reasons," he said, including the cost of health insurance, as well as cost of and access to preventive health services.

Dr. Murtaza Akhter, an assistant professor at the University of Arizona College of Medicine answers MSNBC viewer questions about the coronavirus vaccine.

How long might immunity to the coronavirus last? Years, maybe even decades, according to a new study – the most hopeful answer yet to a question that has shadowed plans for widespread vaccination. These studies "are all by and large painting the same picture, which is that once you get past those first few critical weeks, the rest of the response looks pretty conventional," said Deepta Bhattacharya, an immunologist at the University of Arizona College of Medicine – Tucson who was not involved in the studies.
