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.
Despite recreational cannabis now being legal in 23 states, where more than 100 million Americans reside, studies on the actual health effects are limited. This study is a randomized trial, where each participant will be instructed to consume or avoid cannabis on randomly assigned days during a 14-day monitoring period. The goal of this study is to answer the question: "Does cannabis use increase the frequency of 'early' and abnormal heart beats?" During the 14-day period, participants will wear an external heart monitor, a glucose monitor, and a fitness tracker to track heart rhythm, glucose levels, step counts, and sleep health. Participants will use a mobile app or a text messaging service for daily instructions/reminders on cannabis use, and short surveys. The investigators ask that participants smoke or vape cannabis at least once on days they are instructed to consume cannabis. Compelling evidence of heart and other health effects would be important to the clinical care of our patients.
To compare an investigational oral form of the drug cladribine to the FDA approved form of the drug when it is given by vein (IV).
The primary objective of this study is to evaluate the long-term safety and tolerability of ecopipam tablets in children (greater than or equal to [>=] 6 and less than [<] 12 years of age), adolescents (>=12 and <18 years of age), and adults (>=18 years of age) with Tourette's Syndrome (TS).
The purpose of this study is to evaluate the effect of RBT-1 on reducing the risk of post-operative complications in subjects undergoing cardiac surgery on cardiopulmonary bypass (CPB). A sub-study will also be conducted to evaluate the pharmacokinetic (PK) profile of a single administration of RBT-1 by means of a popPK approach in subjects scheduled to undergo cardiac surgery.
The goal of this clinical trial is to examine the usefulness of a virtual reality-delivered intervention for individuals with opioid use disorder who are taking medication. The main question it aims to answer is will people with opioid use disorder who receive the study intervention, Mindfulness-Oriented Recovery Enhancement in Virtual Reality (MORE-VR), have fewer days in which they use opioids than will people who just receive their usual treatment. Participants will be randomly assigned to either receive 8 weekly sessions of MORE-VR in addition to their usual treatment, or treatment as usual only. Researchers will compare these groups at the end of treatment and three months after treatment is over on number of days of opioid use and time until first opioid use lapse, as well as drug craving and mood.
Iron deficiency (ID) is the most common micronutrient deficiency worldwide, and poor iron bioavailability is a major cause. While 30% of female athletes are affected by ID, and its consequences are highly relevant to athletic performance, ID affects women and children around the world with consequences just as relevant, if not more so (e.g. school performance, work capacity and thus wage earning). With poor iron absorption being a cause of ID in active women, it is especially important to discover simple ways to improve iron (Fe) uptake. While some studies have suggested that consumption of prebiotic fiber may improve Fe absorption in animal models, there have been few studies examining the effects of synbiotic supplementation (consumption of both a prebiotic and probiotic that work together) on Fe uptake in adult females (athletes and non-athletes). A recent pilot study demonstrated a substantial improvement in Fe uptake in female athletes after 4 and 8 weeks of synbiotic supplementation compared to placebo during Fe repletion with a low dose of ferrous sulfate (FeSO4). If synbiotic supplementation can improve the Fe bioavailability of FeSO4 (which is ~30%) in ID women during repletion of Fe status, it could possibly improve the Fe bioavailability of non-heme Fe sources, as well as mixed meals. Research Question: What is the effect of synbiotic supplementation (a supplement containing a prebiotic + a probiotic), compared to prebiotic supplementation or a placebo, on Fe uptake and the gut microbiome in ID athletes during low-dose Fe repletion? Hypothesis: In the proposed study, we hypothesize that synbiotic supplementation along with Fe repletion with a low dose of FeSO4 will have greatest impact on athletes' Fe uptake due to alterations in the microbiome, which will be assessed.
A randomized, double-masked, placebo-controlled safety, tolerability and efficacy study of VRDN-001 in participants with chronic thyroid eye disease (TED)
This is a prospective study to establish the analytical specificity of Bladder EpiCheck test in urine samples from healthy population and urology patients without prior history or evidence of bladder cancer.
Researchers are doing this study to find out if a high fermented food diet is tolerable, and if it will help improve quality of life after surviving a critical illness, including severe COVID-19, by promoting gut health recovery and decreasing gut inflammation.
Over 60 million persons in the United States (US) identify themselves as Latinx and 25.6% are children under the age of 16. Surgical disparities for adults and children have been identified as a major problem in the US and can be experienced at multiple points along a patient's health care trajectory. Data from the investigator's center indicates that a substantial portion of Latinx children who undergo surgery experience high anxiety and postoperative pain as well as postoperative impairments in psychological and physical functioning as compared to White non-Latin children who undergo surgery. Recent growth in use of mobile devices provides us an opportunity to create low-cost mobile health (mHealth) behavioral interventions to reduce this disparity in surgical outcomes. In a previous National Institutes of Health (NIH) award, the principal investigator (PI) developed and tested an evidence based mHealth tailored intervention (WebTIPS) that aims to prepare and be a companion of a child and their family during a surgical event. WebTIPS aims to enhance the recovery of the child in several ways such as reducing anxiety and pain and is based on information provision, modeling, and teaching of coping skills. WebTIPS, however, was developed and validated with a population of primarily White non-Latinx English-speaking children and their parents. Unfortunately, it is well established that mHealth interventions are significantly less effective when used with specific ethnic minorities unless they underwent a process of cultural adaptation. Over the past 4-years, the investigators have established multiple academic and community collaborations, conducted extensive participatory research with Latinx stakeholders and used the heuristic framework and a modified ecological validity model to culturally adapt WebTIPS. The culturally adapted intervention is called L-WebTIPS. The overall aim of this application is to reduce surgical disparities in a population of Latinx children undergoing surgery. The first phase of this application (R61) includes web programming of L-WebTIPS, conduct formative evaluation and conduct feasibly randomized control trial (RCT) to test this intervention. The second phase (R33) includes a multi-center RCT which aims to determine the effectiveness of L-WebTIPS compared to attention control intervention in decreasing postoperative pain, opioids consumption and lowering anxiety in Latinx children undergoing outpatient surgery. Secondary aims of the R33 include examining the impact of L-WebTIPS on home-based clinical recovery parameters such as pain, analgesic requirements, new onset behavioral changes and return to normal daily activity in Latinx children undergoing outpatient surgery. The investigators also plan to determine if the use of L-WebTIPS reduces anxiety and improve experience among the parents of Latinx children undergoing surgery. Finally, the investigators plan to determine if the use of L-WebTIPS reduces anxiety and enhance experience among the parents of Latinx children undergoing surgery. The investigators submit that using a cultural adaption process for an existing validated intervention will accelerate the process of reducing surgical disparities and bringing an effective intervention to clinical settings and routine use.
