Toronto, OntarioAges 18–85 - NCT03035097Recruiting
Study of lung illness for people who served in Southwest Asia
This study is building a research database and stored samples from people who served in the Southwest Asia wars. It may help researchers learn what causes lung problems in veterans and how to better diagnose or treat them.
Denver, ColoradoAges 18 years+ - NCT03149341Enrolling by invitation
MRI and computer-heart simulations for heart disease
This study uses MRI scans and computer simulations to learn more about how the heart and blood flow work in people with certain heart or lung conditions. It may help researchers better understand heart problems and improve future care.
Palo Alto, CaliforniaAges Any age - NCT03209583Recruiting
Test of fast-pacing therapy for congenital heart rhythm issues
This trial studies whether a device-based fast pacing therapy (called ATP) can better treat certain rapid heart rhythm problems in people born with a heart condition. It may help prevent or reduce episodes of atrial (upper-chamber) arrhythmias that occur despite having a pacing/defibrillator device.
Los Angeles, CaliforniaAges Any age - NCT03273049Recruiting
Study of disease processes in children getting liver transplants
This study maps how biliary atresia (a childhood blockage/problem with bile flow from the liver) progresses and changes in the body around the time of a liver transplant. It may help doctors better understand the disease and improve future care.
Pittsburgh, PennsylvaniaAges Any age - NCT03190538Recruiting
Study of fatty liver inflammation in Chinese children
This trial looks at nonalcoholic steatohepatitis (fatty liver with inflammation) in children. It is meant to test whether a new approach can help improve this liver problem without being caused by alcohol or other known liver diseases.
BeijingAges 1–18 - NCT03201094Recruiting
NMES and whey protein for recovery after aneurysmal brain bleed
This pilot study tests whether a therapy that gently stimulates nerves (NMES) and a whey-protein supplement (HPRO) can improve recovery after an aneurysmal subarachnoid hemorrhage (SAH), a type of bleeding around the brain. Participants are usually treated soon after the bleed and stay in the ICU long enough for the study measures.
