A microRNA that can be found in a blood sample may make it easier to detect gastric cancer and could lead to improved treatment for diseases that are resistant to common immunotherapies.

The personal protective equipment industry is trying to inject some clarity into the mask-purchasing experience by creating a uniform set of standards to show consumers how well the products would protect them and those around them. "Whether it's a standard or whether it's something equivalent to the Consumer Reports rating (of) good, better or best, it is probably useful because otherwise people are lost," said Philip Harber, a professor of public health at the University of Arizona who studies the use of respirators. He warned that given some Americans' hostility toward masks, the standards have to be "very, very, very simple."

A promising new biomarker that appears in patients before stomach cancer develops may help with early detection of the disease and improve patient response to therapy, according to findings in a study led by University of Arizona Health Sciences researchers.

A study conducted by researchers at the University of Arizona College of Medicine – Phoenix and an international team shows about 14% of cerebral palsy cases may be tied to de novo genetic mutations or mutations that appear in a child but not in the parents.

There is concern among ophthalmologists that increased screen time might further accelerate the myopia epidemic. “As ophthalmologists, we have now an opportunity to raise awareness among parents and teachers and eventually engage with policy makers and curriculum developers to set up strategies for myopia mitigation that will help students also beyond the pandemic,” said Jordana M. Smith, MD, Associate Professor of Ophthalmology at the University of Arizona College of Medicine – Tucson.

Community spread of the coronavirus is back to the levels Arizona saw in late May, according to Joe Gerald, an associate professor in the University of Arizona Mel and Enid Zuckerman College of Public Health, with increases now in all age groups, not just college students.

University of Arizona Heath Sciences researchers developed one of the most accurate COVID-19 antibody tests available and now have shown antibodies persist for months after infection, providing long-term immunity.

A blood sample may make it easier to detect gastric cancers and could lead to improved treatments for cancers that are resistant to common immunotherapies.

The Mel and Enid Zuckerman College of Public Health marks its 20th anniversary with a special celebration for 20 days.
