The Arizona Department of Health Services is recommending a pause in the use of the single-shot Johnson & Johnson COVID-19 vaccine, following the guidance of federal officials. The University of Arizona does not administer the J&J vaccine and only administers the Pfizer vaccine. The estimated risk of a blood clot from the J&J vaccine is about 1 in a million while the overall risk of dying if you get COVID-19 is about 1 in 100, said Deepta Bhattacharya, an associate professor of immunobiology at the University of Arizona College of Medicine – Tucson.

Adults with osteoarthritis were more likely to use NSAIDs if they were more familiar with the drugs' risks and benefits, new data showed. Patient knowledge – and, by extension, NSAID use – was lower among patients of Hispanic ethnicity. Study author Dr. Ernest Vina, a rheumatologist and researcher at the University of Arizona College of Medicine – Tucson, discusses the findings and their implications.

Mary Beth Putz, a third-year medical student at the UArizona College of Medicine – Phoenix, was surprised with a scholarship from the Arizona Lottery.

Dr. Michael Johnson believes his remote summer internship program will continue opening doors for underrepresented students, even in the post-COVID-19 era.

COVID-19 vaccines will likely provide at least some degree of protection for a long time because there are so many layers of immunity, said Deepta Bhattacharya, an associate professor of immunobiology at the University of Arizona College of Medicine – Tucson. The first shots of the two-shot Pfizer and Moderna vaccines provide reasonable protection. Then the second shot bumps up the level of antibodies and T cells produced by the body, he said.

More than 23% of Arizonans are fully vaccinated against COVID-19. However, the virus still continues to move through the community as thousands of new COVID-19 cases are reported each week. Joe Gerald, an associate professor in the University of Arizona Mel and Enid Zuckerman College of Public Health, calls the trend a "plateau" after a decline in cases following the winter surge. Gerald said looser COVID-19 restrictions and more transmissible variants are part of the reasons why the change in the data.

Dr. Murtaza Akhter, an emergency physician at the University of Arizona College of Medicine – Phoenix, breaks down what the surge of COIVD-19 cases in Michigan means for other states in the U.S.

Researchers are exploring whether perfluoroalkyl and polyfluoroalkyl substances (PFAS) might worsen infections or hamper vaccine effectiveness. Seeking to gauge effects in a particularly hard hit population, a CDC-supported study called AZ HEROES, is tracking COVID-19 infections and antibody levels in Arizona healthcare workers, emergency responders, and other essential workers. The study is led by researchers at the University of Arizona Mel and Enid Zuckerman College of Public Health.

Over the course of the COVID-19 pandemic, people are reporting having what are now known as "pandemic dreams." Michael Grandner, director of the Sleep and Health Clinic at the University of Arizona College of Medicine – Tucson, answers questions from four people about where their dreams have taken them over the past year.

"Outside is protective, but it’s not a total risk eliminator," said Saskia Popescu, an infectious disease epidemiologist and adjunct professor at the University of Arizona Mel and Enid Zuckerman College of Public Health. "When we’re seeing transmission outdoors, it’s people who are close to each other, talking face to face. The three key factors to consider are distance, duration, and intensity," she says.
