This research study is being done to provide comparative data to the Mayo Clinic Adult Congenital Heart Disease Registry.
Evaluation of Outcome Metrics in Alexander Disease
The purpose of this study is to define the natural history of Alexander Disease, a leukodystrophy that causes neurological dysfunction. Investigators will obtain clinical outcome assessments to measure how the disease affects a patient's gross motor, fine motor, speech and language function, swallowing, and quality of life. Specimens are collected …
Microparticles in Obstructive Sleep Apnea
Obstructive sleep apnea (OSA) is independently associated with cardiovascular diseases, including myocardial infarction and stroke. OSA may promote atherosclerosis risk factors such as hypertension, diabetes and dyslipidemia and may have direct proatherogenic effects on the vascular wall. A growing number of studies have recently focused on the role of microparticles …
A Registered Cohort Study on Charcot-Marie-Tooth Disease
The aim of the study is to analyze the natural history data data from Charcot-Marie-Tooth disease and related disorders in China, to assess the clinical, genetic, epigenetic features of patients with Charcot-Marie-Tooth disease, and to optimize clinical management.
Virtual Bronchoscopic Navigation to Increase Diagnostic Yield in Patients With Pulmonary Nodules
Background Transthoracic computed tomography (CT)-guided procedures are the current gold Standard for obtaining diagnostic biopsies of solitary pulmonary nodules (SPN) in the peripheral lung. Novel endobronchial techniques, such as electromagnetic navigation bronchoscopy (ENB) or Virtual bronchoscopic navigation (VBN) are considered safer to approach SPNs. The newest technique combines VBN with …
Biomarkers in the Brain Oxygen Optimization in Severe Traumatic Brain Injury Trial
BioBOOST is a multicenter, observational study of the effect of derangements in brain physiologic parameters on brain injury biomarker levels in patients with severe traumatic brain injury.
EUS-guided Entero-biliary Anastomosis for Therapeutic Access in Benign Biliary Obstructions
Background: Transpapillary EUS-BD (rendezvous/antegrade) is gaining acceptance in BBO. The potential of transmural EUS-BD (hepaticogastrostomy/choledochoduodenostomy) in complex BBO warrants study. Aims: To assess feasibility and efficacy of TEA using transmural covered self-expandable metal-stents (cSEMS) to provide interval biliary drainage and create TAF for biliary endotherapy under cholangioscopy or fluoroscopy in …
Study of Alkaptonuria
The purpose of this study is to gain a better understanding of alkaptonuria and collect medical data on patients who may later participate in new drug trials for this rare genetic disease. In alkaptonuria, a pigment called homogentisic acid collects in bone and connective tissue, causing arthritis and eventually bone …
