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 long-term goal of this work is to determine if combining a highly intensive, task-specific behavioral language intervention with modulation of the efferent cerebellar-cortical pathway using transcranial direct current stimulation (tDCS) has a positive influence on discourse, verbal fluency and working memory in individuals with non-fluent aphasia after stroke. And if these changes can be related to neuroplastic change in the cerebellar cortical pathway indirectly measured through neurophysiologic changes using spectral electroencephalogram (EEG). The initial phase includes the proposed pilot study data from which will be used to inform a larger clinical trial. The primary aims of this pilot are to 1) determine the effect of combining cerebellar tDCS with constraint-induced language therapy (CILT) on language as measured by a verbal fluency task and discourse task in a small population and 2) identify the tolerance of the intervention and barriers to participation measured by the adverse events questionnaire that will inform the methodology of a larger study. The secondary aims include estimating the size of the treatment effect on 1) delta percentage in F3, F7 and Fp1 compared to F4, F8, and Fp2 using resting state EEG spectral analysis and coherence, 2) working memory as measured by the score on the n-back test and 3) quality of life as measured by the Stroke Aphasia Quality of Life survey tool. The secondary aims will be used to determine the utility of these measures in a larger clinical trial. This is a prospective, crossover study, sham-controlled intervention study with two intervention conditions delivered across 6 intervention sessions (3x/week for two weeks) with a 4-week washout in between. Conditions include: 1) sham cerebellar tDCS and 2) real cerebellar tDCS delivered at 2mA across 20 minutes. Each of these will be delivered during CILT intervention with a licensed, certified speech-language pathologist trained in CILT. Once tDCS stimulation has ended, CILT will continue to be delivered for an additional 25 minutes. Assessments of discourse, verbal fluency, working memory and EEG spectral analysis will be conducted at four timepoints, before and after each intervention phase.
The goal of this pilot study is to evaluate the magnitude of changes in glucose and hormone levels in response to structured exercise in the fasting state in individuals with post-bariatric hypoglycemia (PBH). This pilot study will assess the adequacy of a protocol to test the following hypotheses: (1) hypoglycemia will develop in individuals with PBH in response to exercise; (2) counterregulatory hormonal responses to hypoglycemia during exercise are impaired in individuals with PBH.
This is a two-part study. In Part A, eligible participants will undergo a baseline diagnostic liver biopsy to determine non-alcoholic fatty liver disease (NAFLD) Activity Score (NAS) and fibrosis stage, but will not receive study intervention. In Part B, participants with histologically confirmed NAFLD or non-alcoholic steatohepatitis (NASH) will receive study intervention.
The purpose of this study is to evaluate the pharmacokinetics and safety of multiple doses of VX-584 in participants with mild or moderate hepatic impairment as compared to matched healthy controls.
Lifetime risk for developing an alcohol use disorder increases with earlier onset of alcohol consumption. This risk may reflect a tendency for escalated alcohol intake among youth due to immature executive control, leading to more frequent binge drinking, which is associated with more alcohol-related problems. Binge drinking is associated with deficits in behavioral flexibility, which may suggest impaired control networks that contribute to automatic behavior. Individuals with an alcohol or substance use disorder (A/SUD) exhibit attentional bias toward drug- or alcohol-related stimuli that have attained salience through consistent use. Reward history increases attention towards non-drug stimuli, even among individuals with no lifetime A/SUD. Preliminary data (from Dr. Boettiger's lab) from a nationally representative US adult sample using data collected via Prolific found that a questionnaire measure of mindfulness moderates the relationship between alcohol misuse and attention to reward. Given evidence that heavy alcohol drinking impairs behavioral flexibility, which in turn promotes escalating intake, insight into the relationship between mindfulness and behavioral flexibility could inspire new strategies to prevent alcohol and substance use disorders in people at elevated risk.
The number of youth with type 2 diabetes in the U.S. is projected to increase by a staggering 49 percent by 2050, with higher rates among minority youth. The Diabetes Prevention Program (DPP) is recognized as a sentinel study demonstrating the effectiveness of lifestyle interventions for diabetes prevention among pre-diabetic adults but has not yet been replicated in youth. In addition, such intensive interventions are often not sustainable in high risk communities with limited resources. One strategy that has been successfully employed in adults from such communities is peer based health education. However, there have been no peer led interventions in ethnic minority teens and no interventions focused specifically on weight loss for diabetes prevention. Another challenge identified in existing youth health intervention programs is keeping youth engaged to enhance program participation and impact. One potential strategy is the use of mobile technologies (text messaging, mobile applications, social media) to support weight management programs, but to date use of such technologies has largely not been studied in youth. The Principal Investigator's NIH Mentored Patient-Oriented Research Career Development Award (K23) aimed to use CBPR to develop and pilot test a peer-led diabetes prevention intervention incorporating mobile health technologies for at-risk adolescents. Based on results of focus groups which explored strategies for using peer educators and mHealth tools as part of a group lifestyle change program, the researchers did not find existing tools with all the features and functionalities required by users. The investigators therefore began working with teen stakeholders to create a new text messaging platform to support participants as the teens complete the intervention. This R03 research proposal aims to bring together clinical, technology and community experts to further develop and evaluate the mobile health platform. This will provide important pilot data to refine and disseminate the intervention for a larger RCT to be tested in a future R01. Specific Aims: 1. Synthesize real-time data and analytics and conduct user interface (UI) testing to refine and enhance features of the prototype text messaging platform. 2. Investigate the potential for the developed platform to be used as an adjunct to a group educational intervention by examining whether level of use, user satisfaction, and degree of engagement with the platforms modifies behavioral and clinical outcomes.
To determine the effectiveness of an enhanced strategy for daily disinfection in acute care hospital rooms comparing the addition of sani24 to routine daily cleaning versus the control of routine daily cleaning.
The purpose of this study is to determine which method is most effective for teaching the kettlebell swing: verbal cueing, physical constraints, or a combination of the two.
As Dry Needling (DN) continues to see increased use in the clinic, there is a need to establish adverse events that could occur as a result of DN intervention. The adverse events are important to consider when an individual needs to make an informed decision regarding their care. It is important to consider how such information should be presented during the informed consent process to improve an individual's ability to make a sound decision regarding their own personal care.
Incisional dressings aim to prevent contamination of an incisional wound and protect against skin irritation. Surgeons use incisional negative pressure wound therapy (iNPWT) to manage incisional wounds. This study compares a new dressing designed for use with iNPWT that aims to improve comfort, tolerability, and dressing survivability over the standard of care for iNPWT. Further, no evidence exists that shows NPWT reduces the bacterial burden on the skin. This study will compare the incidence of skin irritation, dressing damage or lift, and changes in bacteria flora on healthy volunteer skin.
