Trial of Indication-Based Transfusion of Red Blood Cells in ECMO
NCT05405426
Recruiting
TITRE - Trial of Indication-based Transfusion of Red Blood Cells in ECMO, is a multicenter, prospective, randomized clinical trial. The overarching goal of TITRE is to determine whether restricting red blood cell (RBC) transfusion according to an indication-based strategy for those with bleeding and/or deficit of tissue oxygen delivery, compared with transfusion based on center-specific hemoglobin or hematocrit thresholds, can reduce organ dysfunction and improve later neurodevelopment in critic...

Incentive Processing and Learning in Anorexia Nervosa and Bulimia Nervosa
NCT05056597
Recruiting
The purpose of this study is to investigate areas of the brain responsible for 'liking', 'wanting', and learning in adults with eating disorders using brain imaging techniques, computer tasks, a test meal, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 252 women with an eating disorder (63 AN-restricting type (AN-R), 63 AN-binge eating/purging type... Read More

A Study of Intravesical Enfortumab Vedotin For Treatment of Patients With Non-muscle Invasive Bladder Cancer (NMIBC)
NCT05014139
Recruiting
This study will test a drug called enfortumab vedotin in participants with a type of bladder cancer called non-muscle invasive bladder cancer (NMIBC). This study will also evaluate what the side effects are and if the drug works to treat NMIBC. A side effect is anything a drug does to your body besides treating your disease. In this study enfortumab vedotin will be put into the bladder using a catheter. A catheter is a thin tube that can be put into your bladder.

Cortical Stimulation to Treat Obsessive Compulsive Disorder
NCT04958096

The purpose of this study is to identify abnormal brain signals associated with Obsessive Compulsive Disorder (OCD) and psychiatric symptoms and to investigate novel therapeutic stimulation sites. While treating OCD with standard deep brain stimulation (DBS) therapy, the investigators will also monitor the activity of the anterior cingulate and prefrontal cortex, a region known be involved with OCD, decision making, and emotion regulation, and the investigators will identify abnormal activity co...

Therapeutic Exercise for Rotator Cuff Tendinopathy / Subacromial Pain Syndrome - Outcomes and Mechanisms
NCT04923477
Recruiting
Rotator cuff tendinopathy, one of the pathologies identified as part of the cluster of shoulder symptoms known as subacromial pain syndrome, is a common musculoskeletal shoulder condition. Resolution of pain and disability is poor despite treatment, with only about 50% reporting full recovery at 12 - 18 months. Prior studies suggest therapeutic exercise when used alone and with other interventions can have positive outcomes; however, not all patients with rotator cuff tendinopathy respond. Few s...

Dual Frequency Stimulation in Parkinson's Disease
NCT04650932
Recruiting
Deep brain stimulation (DBS) in the dorsal region of the subthalamic nucleus (STN) is very effective for reducing motor symptoms of Parkinson's disease (PD). Modeling studies suggest that this therapy may result in current spread into the ventral STN, causing altered cognitive processes. As a result, current stimulation parameters often lead to worsening in verbal fluency, executive function, and, particularly, cognitive control. There is evidence suggesting that low frequency oscillatory activi... Read More
