What does it mean to live with a sound that has no external source? For millions worldwide, this is the daily reality of tinnitus—a complex auditory symptom that can range from a minor annoyance to a deeply distressing condition. This "universe" of sound is the primary focus of Anna Carolina Marques Perrella de Barros, an audiologist and researcher from the Tinnitus and Sound Intolerance Group at the Universidade Federal de São Paulo in Brazil. Her pursuit of advanced clinical management strategies and research collaboration brought her to the University of Iowa as an Obermann International Fellow.

A pregnant woman in rural Iowa must make so many extra decisions about her and her baby’s health. It isn’t just whether she should go to the hospital about unexpected complications, but which one. If she goes to the closest hospital, will it have the expertise to treat her? If not, will it have an ambulance that can transfer her to a more urban hospital? One Iowa mom facing these questions inspired Stephanie Radke, clinical associate professor of obstetrics and gynecology at the University of Iowa, to found the Iowa Perinatal Quality Care Collaborative (IPQCC). IPQCC is responsible for improving communication and collaboration among groups addressing obstetrical and neonatal care in Iowa, especially in rural communities.
