Patient Reported Outcomes Due to Bladder Neck Obstruction in Women Treated With Botulinum Toxin A Injection.

Introduction: Primary bladder neck obstruction (BNO) occurs when the bladder neck fails to open during voiding, causing urinary symptoms despite no anatomic obstruction. The cause of BNO is unclear but may involve neurogenic dysregulation related to the sympathic nervous system such as upper motor neuron lesion or peripheral autonomic neuropathy (small fiber neuropathy (SFN)). Another etiology can incuded increased sympathetic tone secondary to anxiety or stress conditons.

Barriers to diverse clinical trial participation in Duchenne muscular dystrophy: Engaging Hispanic/Latina caregivers and health professionals.

Background: Despite the increasing availability of clinical trials in Duchenne muscular dystrophy, racial/ethnic minorities and other populations facing health disparities remain underrepresented in clinical trials evaluating products for Duchenne. We sought to understand the barriers faced by Hispanic/Latino families specifically and underrepresented groups more generally to clinical trial participation in Duchenne.

Methods: We engaged two participant groups: Hispanic/Latino caregivers of children with Duchenne in the US, including Puerto Rico, and health professionals within the broader US Duchenne community.

Bowel bladder dysfunction in control children in a pediatric urology office.

Introduction: Bowel bladder dysfunction (BBD) is common in children. Risk factors for BBD include age, gender, obesity, and behavioral issues such as ADHD. We investigated the modified Swedish Bowel-Bladder questionnaire as a sensitive indicator of BBD in healthy children.

Site-Specific Fluorescence Polarization for Studying the Disaggregation of α-Synuclein Fibrils by Small Molecules.

Fibrillar aggregates of the protein α-synuclein (αS) are one of the hallmarks of Parkinson's disease. Here, we show that measuring the fluorescence polarization (FP) of labels at several sites on αS allows one to monitor changes in the local dynamics of the protein after binding to micelles or vesicles, and during fibril formation. Most significantly, these site-specific FP measurements provide insight into structural remodeling of αS fibrils by small molecules and have the potential for use in moderate-throughput screens to identify small molecules that could be used to treat Parkinson's disease.
