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.
This is a pragmatic phase III, randomized, blinded, double placebo-controlled, three-arm trial of elderly patients following cardiac surgery to assess the relationship between nighttime intravenous (IV) and sublingual dexmedetomidine on postoperative delirium and functional outcomes after surgery.
The goal of this double-blind, placebo-controlled randomized clinical trial is to test the effect of 12 weeks of orally administered MitoQ (mitoquinol mesylate) supplementation on cognition in 50 people with early phase schizophrenia-spectrum disorders (E-SSD) who have mitochondrial dysfunction (called high risk, or HR). Cognitive impairments in SSD can cause significant disability. Yet, there are no effective treatments for cognitive impairments in SSD. It has been shown that alterations in a certain type of brain cell (parvalbumin interneurons, or PVI) underlie cognitive deficits in SSD. These PVI, which fire at a fast rate, utilize high amounts of energy from the mitochondria and are highly vulnerable to oxidative stress. MitoQ is an antioxidant. Research has shown that, in mice, MitoQ can reduce oxidative stress in the mitochondria. The main question that this clinical trial aims to answer is: • Does MitoQ supplementation, compared to placebo, improve cognition in HR patients? Secondary questions that this clinical trial aims to answer are the following: Does MitoQ supplementation, compared to placebo: - Improve positive and negative symptoms of SSD in HR patients? - Improve functioning in HR patients? - Improve/normalize blood markers of mitochondrial dysfunction in HR patients? The investigators will enroll 100 individuals with E-SSD. These enrolled participants will participate in an initial screening visit to determine if they qualify for the actual clinical trial. At the screening visit, the investigators will ask about psychiatric history to determine diagnosis; ask about medical history; do a physical exam; collect blood and urine samples; do a pregnancy test; and ask participants to bring in their current medications in their original packaging so it is known what they are taking. After the screening visit, the investigators will invite 50 HR patients (identified with a blood test) to continue with the clinical trial. Participants who qualify for the clinical trial will be asked to: - Take a supplement (MitoQ or placebo) once per day for 12 weeks in addition to their usual medications. - Come in for a study visit every 4 weeks over the 16-week study period. At these study visits, the investigators will do a physical exam; ask about symptoms and side effects; take blood and urine samples; and ask questions about general health and well-being, quality of life, mental health, emotional health, and mood. At visits 1 (baseline) and 4 (12 weeks), participants will also take a cognitive assessment.
This study will use a randomized controlled trial design to evaluate the effect of two evidence-based treatments for adults with mild-moderate Primary Progressive Aphasia (PPA). The aim of the study is to help us better understand the effects of speech-language therapy on communication abilities in individuals with PPA.
Complete and timely colonoscopy after an abnormal stool-based colorectal cancer screening test results in early detection, cancer prevention, and reduction in mortality, but follow-up in safety-net health systems occurs in less than 50% at 6 months. The proposal will implement multi-level approach consisting of a stepped-wedge clinic-level intervention of team-based best practices co-developed with primary and specialty care, a patient-level technology intervention to provide enhanced instructions and navigation to complete diagnostic colonoscopy, and a mixed methods evaluation to explore multi-level factors contributing to intervention outcomes. Developing a solution to this high-risk and diverse population has the potential to translate to other health systems, support patient self-management, and address other patient conditions.
The aim of the proposed clinical trial is to study the use of the Dexcom G7 continuous glucose monitor (CGM) within the intensive care unit (ICU) environment. The overall goal is to validate the accuracy and practicality of the Dexcom G7 when used to assess glycemia in critically ill patients.
The aim of this protocol is to assess the presence and severity of primary aldosteronism pathophysiology in patients with type 2 diabetes who have, or are at-risk for developing, chronic kidney disease.
A randomized, sham-controlled, double-blind clinical trial to examine the safety and effectiveness of tRNS on unmedicated pediatric patients (7-12 years) with ADHD. Subjects will undergo either tRNS or sham treatment for 10 days during a two-week period in a home-simulated environment. Each treatment session is 20 minutes, during which their attention will be maintained using a software game.
This is a Phase II, randomized, double-blind, placebo-controlled, multi-center study to evaluate the clinical efficacy and safety of Antimicrobial Peptide PL-5 Topical Spray in patients with mild infections of diabetic foot ulcers. Eligible subjects will be randomized (1:1:1) to receive twice a day, 14 days treatment of Antimicrobial Peptide PL-5 Topical Spray (1‰), Antimicrobial Peptide PL-5 Topical Spray (2‰) and topical placebo (vehicle) spray. In this study, the cut-off date for final analysis is defined as the time when all subjects have completed the last visit or discontinued the study
To evaluate the safety and efficacy of the Cleaner™ Pro Thrombectomy System for aspiration thrombectomy in patients with acute pulmonary embolism (PE).
Anxiety and depression symptoms occur at high rates in Veteran populations and can significantly impact function, compromising the ability to work and to successfully form and maintain valued relationships. Several other symptoms commonly occur with anxiety and depression, including poor sleep quality and chronic pain. Since all these symptoms frequently occur together, they may have a common underlying biological basis. A single medication that could effectively treat all these symptoms would be ideal. Converging data suggest that pregnenolone is a promising pharmacological agent for treating multiple psychiatric symptoms and functional impairment. The investigators thus propose to conduct a clinical trial of pregnenolone in Veterans with anxiety and depression symptoms. Pregnenolone has minimal side effects, and the prior research demonstrates that pregnenolone is well-tolerated by Veterans. Treatment with pregnenolone could thus be an efficacious new therapeutic for Veterans experiencing depression, anxiety, poor sleep quality and chronic pain conditions.
