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.
Study aims to examine the influence of out of plane interscalene approach to a brachial plexus block on the effect of phrenic nerve blockade.
This study compares the efficacy of two intervention strategies for improving social outcomes for autistic adolescents and young adults when interacting with unfamiliar non-autistic peers.
This study evaluates the efficacy of high-dose fish oil in decreasing rates of gastrointestinal bleeding in patients with continuous-flow left ventricular assist devices. Half of the patients without history of bleeding will receive fish oil while the other half will not. Half of the patients with history of bleeding will receive fish oil while the other half will not. Markers of angiogenesis and inflammation, as well as changes in the microbiome will be assessed in each group.
The objectives of the protocol are to: (1) evaluate the uptake of cascade screening and preventative therapies after the implementation of a simplified screening process and (2) assess proband and family member perspectives about the return of research results and cascade screening for the KCNQ1 Thr224Met variant. The investigators will conduct a mixed methods study in the Old Order Amish community where the KCNQ1 variant is enriched over 100,000-fold compared to other populations. The intervention will offer free, mail-in, saliva-based genetic testing for family members of probands. The rate of uptake of testing and preventative therapy after the intervention is implemented (i.e. when 'simplified' free, mail-in, saliva-based testing was available) will be compared to data from before the intervention (i.e. when 'traditional' $50 blood-based testing was available to family members) when uptake was essentially zero. The primary outcome is the rate of uptake of cascade screening with the intervention ('simplified'). The secondary outcomes include: extent of disclosure of genotype results before and after the intervention, proportion of informed relatives who get screened before and after the intervention, and the uptake of appropriate preventative care (e.g. seeing a cardiologist and/or taking beta-blocker). The tertiary outcomes are demographic characteristics associated with uptake of cascade screening or uptake of preventative therapy. The investigators will also assess qualitative themes surrounding the return of results process and cascade screening using interviews.
This study is designed to evaluate the safety and efficacy of deflazacort in participants with LGMD2I. Most participants enrolled will have a screening visit and 3 additional visits (after 1, 13, and 26 weeks of treatment).
This clinical investigation is an open-label, multi-center RCT to demonstrate the safety and effective performance of the Lungpacer DPTS (plus standard of care) as compared to Control (standard of care only) in patients aged 18 years or older who are receiving mechanical ventilation. Eligible Subjects will have received mechanical ventilation for ≥96 hours (4 days) and failed two weaning attempts. The goal or outcome is to show a numerically greater proportion of subjects weaned in the Treatment (Lungpacer DPTS) group as compared to the Control group.
This study is designed to investigate the treatment response of lymphedema, of the upper or lower extremity, during clinical, pharmacologic treatment of lymphedema with oral ketoprofen. Correlation of clinical responses (changes in limb volume and skin thickness) with changes in the inflammasome will help to define the molecular substrate of treatment response.
The purpose of this study is to determine if pain can be relieved by delivering small amounts of electricity (called "electrical stimulation") to the nerves in an individual's amputated leg.This study will involve the use of a Peripheral Nerve Stimulation (PNS) System that is made by SPR Therapeutics (the sponsor of the study). The PNS System was cleared by the FDA for up to 60 days of use for the management of chronic pain, including extremity (leg) pain.
The proposed research, building on an ongoing AHRQ-funded research project to prevent pediatric diagnostic errors in primary care (R01HS023608) and using a prospective, cluster-randomized, stepped wedge design, will investigate whether 1) a quality improvement collaborative (QIC) intervention without subspecialist involvement, 2) a QIC with subspecialists and primary care physicians (PCPs) mutually engaged, and/or 3) a hub and spoke co-diagnosis, co-management model where PCPs diagnose and manage pediatric hypertension (HTN) with a supporting subspecialist advisor, reduce errors in pediatric HTN diagnosis and management compared to each other and usual care.
The primary objective of this study is to determine if tomato-soy juice can reduce inflammation, which is linked to chronic disease
