Breathing MRI using xenon gas to study lungs
This trial uses a special breathing MRI (you breathe a gas mixture) to measure how well your lungs work. It studies healthy kids and people with lung conditions like cystic fibrosis or asthma, and it may help researchers better understand lung function and flare-ups.
Toronto, OntarioAges 8 years+ - NCT02113644Recruiting
Prevent CardioKids for overweight children after the COACH program
This trial looks at ways to help children who are overweight or obese reduce future heart and health risks. It compares children in different groups based on weight and, for some, whether they are having elective surgery.
Maastricht, LimburgAges 6–18 - NCT02855554Recruiting
MRI heart scan study for specific heart conditions
This study uses a special MRI approach to measure details of your heart muscle in people with certain heart problems. It may help researchers better understand how different conditions affect the heart and how those changes can be measured.
Charleston, South CarolinaAges 18–90 - NCT02143986Recruiting
Testing glycosylated ferritin to evaluate inflammation
This trial looks at a blood test called “glycosylated ferritin” to help doctors better identify certain dangerous inflammatory conditions. It may help clarify whether your high iron-related marker is due to inflammation rather than other causes.
BrusselsAges Up to 85 years - NCT02147405Recruiting
PET scans and lymph node checks for HIV immune rebound
This study looks at people with HIV who either have not started HIV medicines yet or who recently started/changed them and may develop immune rebound (IRIS). It uses blood tests and optional PET/CT scans and lymph node biopsies to understand what’s happening in the body and to guide care.
Bethesda, MarylandAges 18–100 - NCT02119611Recruiting
Deep brain stimulation for Parkinson’s, dystonia, or tremor
This study tests deep brain stimulation (DBS), a therapy that sends electrical signals to the brain, for movement problems like Parkinson’s disease, dystonia, and essential tremor. It may help people whose symptoms are not controlled enough with medications, or who already have a DBS device and need ongoing management.
Bethesda, MarylandAges 18–100 - NCT02755974Recruiting
Study of COPD flare-ups in adults with reduced lung function
This study follows people with COPD flare-ups (sudden worsening of breathing) to better understand what happens and what might help. You may be asked for consent and lung-function tests if you meet the breathing and age requirements.
