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.
First Responders are expected to maintain high-performance levels under extreme conditions. However, constant intense workplace stress, physical work demands, and irregular shift hours are taking a severe toll on frontline workers. These demands often lead to physical and mental health problems, poor job performance, and lifestyle issues. Without better support and resources, these demands will continue to cause first responders to be trapped in a vicious cycle that typically includes occupational trauma, stress, and maladaptive coping skills. The purpose of this research is to: 1. Better understand the physiological, psychological, and cognitive impacts workplace stress and irregular shift hours have on first responders 2. Better understand the most prominent challenges first responders face when trying to manage their own physical and mental health. Through the results of this study, we hope to identify possible solutions/interventions at the individual, clinical and departmental levels to help first responders better manage their stress and improve their quality of life.
This study seeks to understand the performance of MRI to characterize pancreatitis and predict chronic complications (endocrine and exocrine) of pancreatitis. Through multiple aims, the investigators will benchmark MRI against relevant reference standards (e.g. endoscopic pancreatic function tests, laboratory data). The investigators will also characterize repeatability of the imaging findings and will work to develop methods to simplify and automate analysis of the MRI images. Research interventions depend on the Aim(s) participants enroll in but include: endoscopic pancreatic function testing (added on to clinically indicated upper GI endoscopy), blood tests, stool tests, gene sequencing, and survey completion. All participants will undergo research MRI examinations, a subset of which will include administration of intravenous secretin.
Obsessive-compulsive disorder impacts 1-2 percent of the population. Unfortunately, about fifteen percent of patients fail to benefit from existing therapies. A small number of OCD patients, who have a disabling illness that does not improve after conventional treatments, have neurosurgery as a last resort. One procedure, capsulotomy, involves making pairs of lesions in an anatomically-defined part of the anterior limb of the internal capsule, a structure containing nerve fiber bundles connecting the thalamus, in the center of the brain, to the prefrontal cortex, the most anterior and outermost brain region. The investigators will examine how the therapeutic effects of capsulotomy relate to changes in the structure of these brain pathways with structural (diffusion tensor imaging, DTI) and functional (resting-state and task-based) connectivity metrics. The investigators will also utilize experimental cognitive tasks that are sensitive to the circuitry impacted by this procedure.
This study will recruit women scheduled to undergo vaginal apical suspension surgery (either uterosacral ligament suspension or sacrospinous ligament fixation) with or without other prolapse or anti-incontinence procedures. Participants will be randomized 1:1 to preoperative gabapentin or preoperative placebo (both patients and investigators will be blinded). Note the control group will receive preoperative acetaminophen/celecoxib/placebo and the treatment group will receive preoperative acetaminophen/celecoxib/gabapentin (preoperative acetaminophen/celecoxib are part of our current ERAS protocol). The primary outcome will be postoperative opioid use in the first 24 hours postoperatively measured in morphine milligram equivalents.
A study evaluating HPV vaccine uptake among unvaccinated patients between the ages of 18 and 35 of a mobile health clinic serving the Mississippi Delta.
The goal of this observational study is to test the NuView device in participants with familial adenomatous polyposis (FAP). The main question it aims to answer is: - can the papilla be visualized using a forward-facing endoscope outfitted with the NuView device. Participants will undergo standard of care esophagogastroduodenoscopy with an additional endoscopic exam using NuView device, for which participant have given prior consent.
Broadly, this study (SCN-BP) seeks to examine sleep and circadian factors that contribute to blood pressure levels at night.
The purpose of this study is to evaluate the effects on folic acid supplementation in a population living in an environment with chronic arsenic exposure in Birmingham, Alabama.
High-risk polypharmacy is common among older adults in the United States, is particularly dangerous for individuals with dementia or cognitive impairment, and is associated with harms such as adverse drug reactions, falls, and higher costs of care. This project aims to test in a pragmatic clinic-randomized controlled trial two electronic health record-based behavioral economic nudges to help clinicians reduce high-risk polypharmacy among their older adult patients and in the subgroup with dementia or cognitive impairment. The main questions this trial aims to answer are: Aim 1: To evaluate the effects of an EHR-based commitment nudge, a justification nudge, and the combination of both nudges on a composite measure of high-risk polypharmacy via a pragmatic randomized controlled trial. The investigators will use cluster randomization in which primary care clinics are randomized to receive 0, 1, or 2 nudges using a factorial design. The nudges will run for 18 months, followed by 12 months of observation to assess persistence of effects. Aim 2: To qualitatively and quantitatively assess clinician experiences with the EHR-based nudges, including their acceptability and effects on workflow. At the conclusion of the intervention period, the investigators will perform semi-structured interviews and field a clinician survey.
To evaluate the effects of tradipitant relative to placebo on gastric motor functions, satiation, and postprandial symptoms in patients with functional dyspepsia.
