Investigator: Amy Rapp, PhD
Status: Closed
The goal of the project is to identify differences in learning in obsessive-compulsive disorder (OCD) by measuring the activity of the brain while participants complete computer tasks. Eligible participants will be asked questions about their medical and psychiatric history and perform tasks on a computer while an electroencephalogram (EEG) is recorded.…
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Rebecca Straus Farber, MD
Status: Closed
This study will be used to evaluate the immunologic effects of Prebiotics (soluble fiber required by beneficial bacteria), in comparison to Probiotics (beneficial bacteria), in individuals with Multiple Sclerosis (MS) and Clinically Isolated Syndrome (CIS).
Condition: Heart Disease / Coronary Artery Disease
Investigator: Ajay Kirtane, MD, SM
Status: Closed
This study is trying to determine if using a Dynamic Coronary Roadmap (which is a software used along with an x-ray imaging system) reduces the total iodine contrast volume per Percutaneous Coronary Intervention (PCI) procedure compared to procedures performed without Dynamic Coronary Roadmap. This X-ray system provides imaging support while directing the…
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Victoria Leavitt, PhD
Status: Closed
ASPIRE is a clinical trial to investigate aspirin as a treatment to improve exercise performance in people with multiple sclerosis (MS) who experience overheating during exercise. Persons with multiple sclerosis benefit from exercise, but many avoid it because of exhaustion and overheating. This randomized controlled trial (RCT) tests aspirin as a method to…
Condition: Heart Disease / Coronary Artery Disease
Investigator: Susheel Kodali, MD
Status: Closed
This is a research study designed to look at the safety and effectiveness of the TriGUARD 3 cerebral embolic protection device in patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of the study is to assess whether the TriGUARD 3 can prevent death, stroke, more subtle signs of brain injury, and/or silent brain injury as measured…
