Longitudinal changes of swallowing safety and efficiency in infants with spinal muscular atrophy who received disease modifying therapies.

Background: Dysphagia is a common feature of the natural history of patients with spinal muscular atrophy (SMA). Literature regarding swallowing safety and efficiency is scarce in patients with SMA, particularly in the era of newborn screening programs and disease-modifying therapies.

Objective: To describe the longitudinal changes of swallowing safety and efficiency in children with SMA who received one or more disease modifying therapies METHODS: Case series of patients with SMA followed at the University of Florida from 1 May 2019 to 31 December 2022 who had two or more videofluoroscopy swallowing studies (VFSS), with the first being within 30 days of their first treatment.

Perspectives of the Friedreich ataxia community on gene therapy clinical trials.

Gene therapy is a potential treatment for Friedreich ataxia, with multiple programs on the horizon. The purpose of this study was to collect opinions about gene therapy from individuals 14 years or older with Friedreich ataxia or parents/caregivers of Friedreich ataxia patients who were diagnosed as children 17 or younger. Participants were asked to complete a survey after reading brief educational materials regarding gene therapy.
