There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this retrospective observational cohort study is to assess pregnancy and infant outcomes in three groups: the first is women with ulcerative colitis (UC) who were exposed to ozanimod during pregnancy; the second is women with UC exposed to conventional therapy during pregnancy; the third is women with UC exposed to advanced therapy during pregnancy. This study will use data from a large US healthcare claims database.
This is a single-center, prospective, randomized, controlled (crossover) clinical study designed to investigate the specific dose-response impact of insulin infusion rate (IIR) on blood glucose levels during a pancreatic clamp study in the setting of dexamethasone-induced insulin resistance. The investigators will recruit participants with a history of overweight/obesity but no history of prediabetes or diabetes. Participants will be rendered temporarily insulin resistant by taking seven doses of dexamethasone. They will then undergo two pancreatic clamp procedures in which individualized basal IIR are identified, followed in one by maintenance of basal IIR (maintenance hyperinsulinemia, MH) and in the other by a stepped decline in IIR (reduction toward euinsulinemia, RE). In both clamps the investigators will closely monitor plasma glucose and various metabolic parameters. The primary outcome will be the absolute and relative changes in steady-state plasma glucose levels at each stepped decline in IIR.
The goal of this study is to evaluate the effectiveness of a standardized lymphedema and fibrosis self-management program (LEF-SMP) to improve LEF self-management and reduce LEF-associated symptom burden, functional deficits, and improve quality of life in head and neck cancer (HNC) survivors.
The goal of this study is to evaluate patient perception and preference in physician attire. Eligible subjects admitted to medical-surgical hospital unit will complete a survey expressing perceptions and preference regarding physician attire.
The purpose of this research is to evaluate if intervention and education can change the behavior of someone's willingness to see an eye care provider to prevent blindness and glaucoma. The researchers are investigating if adding additional resources improves participant access to care.
The purpose of this study is to test if four different programs (prolonged overnighting fasting alone, exercise alone, a combination of prolonged overnight fasting and exercise, or general health education sessions alone) can reduce fatigue in women with advanced or metastatic breast cancer who are receiving a medication called a cyclin-dependent kinases-4 and 6 (CDK4/6) inhibitor.
The investigators will randomly assign participants with social anxiety disorder to receive oral cannabidiol (CBD) or placebo. Participants will undergo a fear conditioning and extinction trial, and the investigators will examine whether CBD increases the degree of fear reduction during extinction.
Osteonecrosis of the femoral head (ONFH) is a debilitating musculoskeletal disease that is characterized by localized death of bone cells and associated cellular elements within the subchondral bone. If it progresses, it results in the collapse of the femoral head (ball part of the hip) giving rise to secondary arthritis. This condition is associated with marked pain and loss of function, often necessitating a joint replacement. Due to the relatively young age of onset of ONFH (often in 20s and 30s), there is great interest in utilizing joint-preserving procedures prior to the need for joint replacement. Joint-preserving procedures include core decompression (CD) with and without bone grafts or cells, vascularized and non-vascularized bone grafting, as well as osteotomies. Inconsistent results for each of these procedures have been reported and there are no Clinical Practice Guidelines or medical community consensus opinions regarding the treatment of early-stage ONFH. The hypothesis to be tested is "Participants who have early-stage ONFH undergoing CD augmented with autogenous bone marrow aspirate concentrate will have better clinical and radiological outcomes than CD alone." This multi-center randomized controlled trial for early-stage ONFH is prospective and controlled for participant stage (only early-stage pre-collapse individuals) and surgical technique. Participants will be evaluated as per routine surgical follow-up, and at 6 months (telemedicine), 1- and 2- years using radiographs, MRIs, and questionnaires. This project will also explore the scientific basis for success vs. failure in individuals who have osteonecrosis, and have different demographics and bone marrow aspirate cell profiles.
Both Tart Cherry and Omega 3 FAs have better side effect profiles compared to other commonly used medications for AIMSS, such as nonsteroidal anti-inflammatories, steroids, and serotonin norepinephrine reuptake inhibitors. Additionally, in our clinics the investigators often find that patients tend to be more receptive to taking a supplement as opposed to an additional medication. Further, both Tart Cherry concentrate and fish oil have beneficial properties for helping with joint stiffness in general, in addition to other health issues like insomnia. There is some evidence in mouse models that when given together, these supplements may have an even greater anti-inflammatory effect than when taken separately. Although to our knowledge, no human studies have tested this hypothesis. This study has been designed to test the hypothesis that Tart Cherry and fish oil when given in combination over a 12-week period could produce beneficial changes in arthritis symptoms when compared to a control group in an obese breast cancer population experience AIMSS and on an AI. Secondary outcomes to be assessed include pain, functional performance, quality of life and cognition.
