Health professionals trained to work together can give children with severe pulmonary diseases better, more holistic care.

Continuing coverage: A recent study led by University of Arizona Health Sciences researchers found that COVID-19 antibodies can last between five and seven months after recovery. However, contradictory research suggests that they fade within weeks.

While the days leading up to most presidential elections carry a certain frenzied, exhausted energy fueled by attack ads and nonstop robocalls, this election cycle has felt abnormally anxiety-inducing for many Americans. “We’re certainly in the middle of a perfect storm,” said Dr. Esther Sternberg, research director at the Andrew Weil Center for Integrative Medicine at the University of Arizona. Humans respond physiologically to stress — we sweat, our hearts race — and those responses, Sternberg said, are essential for our survival.

Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix, is interviewed about how sudden changes in temperature can impact a person's health.

Dr. Elaine Situ-LaCasse, an associate professor and emergency ultrasound faculty at the University of Arizona College of Medicine – Phoenix, is leading a study to design an educational program teaching rural health care professionals about the use of lung ultrasound technology remotely.

The goal of reaching immunity for COVID has been intensely debated and we have new research on antibodies to throw into the mix. Dr. Deepta Bhattacharya, an immunobiologist and The Today Show - Hoda/Jenna associate professor and at the University of Arizona College of Medicine in Tucson, talks about his recent study published in the journal Immunity, to determine whether people who are infected are immune from reinfection and, if so, for how long.

Our sudden surge of winter weather is hitting the high country really hard. Some folks woke up to a foot of snow this morning. "When you have that big of a change in temperature, that drastic change, it means the body also has to adjust itself more quickly than normal," said Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix.

Antibodies that may protect against COVID-19 in people who have previously had the virus declined over the summer, according to a new study that could throw doubt on the idea that a population can develop herd immunity. A University of Arizona Health Sciences Study that examined a sample of nearly 6,000 COVID-19 patients, showed that antibodies persist for months after infection, providing long-term immunity. “We clearly see high-quality antibodies still being produced five to seven months after SARS-CoV-2 infection,” said Deepta Bhattacharya, associate professor of immunobiology, at University of Arizona College of Medicine.
