This year, an estimated 785,000 people will experience their first heart attack, according to the American Heart Association. During that same period, some 470,000 people, who have already had one or more heart attacks, will have another. But an intervention program known as cardiac rehabilitation could help reduce both of those sobering figures.
Health professionals working with cardiac rehabilitation develop individualized plans for cardiology patients that target specific problems such as poor diet, stress, smoking, lack of exercise, and other lifestyle factors that affect heart health.
UAB cardiologist Vera Bittner, M.D., medical director of the Coronary Care Unit and the UAB Cardiac Rehabilitation Program, recently reported that, in an analysis of data taken from the Medicare database, cardiac rehabilitation lowered the death rate among participating patients by as much as 35 percent compared to non-participants with similar heart problems.
Alumnus Boosts Nation’s Drug Defenses

If there is trouble somewhere in the world, Michael V. Callahan, M.D., DTM&H, M.S.P.H., probably isn’t far away. For three months every year, Callahan, a 1991 graduate of the UAB School of Public Health and 1995 graduate of the UAB School of Medicine, works in the Division of Infectious Diseases at Massachusetts General Hospital. The rest of his time is spent on the move.
Callahan has been on the scene at some of the world’s most famous—and dangerous—virus outbreaks, including H5N1 avian flu in Hong Kong in 1999 and 2001, SARS in Hong Kong in 2003, Marburg in Angola in 2004, and so on. He also has responded to recent Ebola virus outbreaks in the Democratic Republic of the Congo, Lassa fever in Nigeria, and controversial laboratory accidents resulting in the infection of scientists at foreign biohazard laboratories.
But Callahan’s most enduring contribution to health care may come from the lab rather than the field. Since 2005, he has been a program manager for the Defense Advanced Research Projects Agency (DARPA), the secretive R&D center of the American military. Callahan was recruited to DARPA “to work on fast-paced solutions to health threats,” he says. His biggest mission: Create a government-funded drug research and production capability focused strictly on national priorities, such as defense and pandemic preparedness, rather than profits. “The Department of Defense had no idea how to make drugs, and neither did I,” Callahan recalls. But they knew they needed to learn how.
Taking Sleep Science into the Bedroom

You may think you're getting enough sleep, but your wrist might tell a different story.
Using a motion-sensing chip built into a wristwatch-shaped device, sleep scientists can create a highly accurate map of a person’s daily cycle of sleep and wakefulness. The method is called actigraphy, and UAB investigators are using it to take the university’s sleep research program to a new place: patients’ own bedrooms.
“An overnight sleep study is the gold standard” in order to get a precise understanding of a person’s sleep issues, says Kristin Avis, Ph.D., associate director of the Pediatric Sleep Disorders Center at Children’s of Alabama and associate professor of pediatrics at UAB. Overnight sleep studies are routinely conducted for adults at UAB Highlands Sleep Wake Disorders Center and for children at the Pediatric Sleep Disorders Center at Children’s of Alabama. “But in many cases, we would like to establish what a patient’s sleep pattern is over time, and how they sleep in their everyday environment," says Avis. "And we can’t do that in the clinic.”
