Development and Validation of Patient Reported Outcome (PRO) Measures for Individuals With Neurofibromatosis 1 (NF1) and Plexiform Neurofibromas (pNFs)

Feb 3rd, 2023 - Background: Neurofibromatosis 1 (NF1) is a genetic disease with multiple clinical manifestations, including plexiform neurofibromas (pNFs) that can cause pain and may significantly impact daily functioning and quality of life (QOL). Patient-reported outcomes (PROs) are useful in trials for conditions that are disabling and chronic like NF1, where symptom reduction and improved functioning and Q...

The Pediatric Spine Foundation

Feb 3rd, 2023 - The Pediatric Spine Foundation is a registry designed to assist spine surgeons to efficiently identify and track patients with chest wall and spinal disorders. The registry allows spine surgeons to participate in retrospective and prospective studies for specific spinal disorders.

Biomarkers of Uterine Muscle Physiology

Feb 3rd, 2023 - Elevated amniotic fluid lactate (AFL) and uterine electromyography (EMG) mathematically transformed to calculated the power density spectrum median frequency have been found separately to be associated with labor dystocia and cesarean birth. Both are hypothesized to reflect that uterine fatigue plays a role in the pathophysiology of labor dystocia for some women. This study aims to characterize...

Natural History, Management, and Genetics of the Hyperimmunoglobulin E Recurrent Infection Syndrome (HIES)

Feb 3rd, 2023 - The Hyper IgE Syndromes (HIES) are primary immunodeficiencies resulting in eczema and recurrent skin and lung infections. Autosomal dominant Hyper IgE syndrome (AD-HIES; Job's syndrome) is caused by STAT3 mutations, and is a multi-system disorder with skeletal, vascular, and connective tissue manifestations. Understanding how STAT3 mutations cause these diverse clinical manifestations is critic...

Human Movement Database

Feb 3rd, 2023 - The purpose of this study is to develop a database of normative and adaptive control strategies for human motion.
