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 purpose of this research study is to investigate the relationship between light and circadian rhythms. Twenty healthy older adults will be recruited to participate in a randomized, cross-over study, where an active lighting intervention designed to maintain entrainment and a control intervention designed not to entrain will be tested.
This study investigates whether television viewing or music listening can reduce pre-operative anxiety and improve surgical outcomes for patients undergoing cataract surgery. It aims to determine the effectiveness of these interventions compared to a control group and assess their impact on physiological markers of anxiety as well as the incidence of intra-operative hypertensive events. The key questions that are to be answered are: 1. Does watching television before cataract surgery decrease intraoperative hypertensive events and/or pre-operative anxiety in patients? 2. Does listening to music before cataract surgery decrease intraoperative hypertensive events and/or pre-operative anxiety in patients?
This study will compare how safe and effective sacituzumab tirumotecan is versus the treatment of physician's choice (TPC) in participants with advanced/metastatic gastroesophageal adenocarcinoma. The primary hypothesis of this study is sacituzumab tirumotecan is superior to TPC with respect to Overall Survival (OS).
The purpose of this research is to identify a biomarker that is exists when human papillomavirus (HPV) mediated oropharyngeal squamous cell carcinoma is present and does not exist when HPV mediated oropharyngeal squamous cell carcinoma is absent.
The investigators propose the Gluten Free Nutrition Optimization through Ultra-processed food Reduction and Improved Strategies for Health (GF-NOURISH) study to demonstrate the feasibility and success of a nutritional education program focused on naturally occurring gluten-free foods and minimizing ultra-processed gluten-free foods. The investigators hypothesize that nutritional educational (GF-NOURISH) intervention will have multiple health benefits
This project aims to assess the effectiveness of using a Respiratory Muscle Training (RMT) device during high-intensity functional training (HIFT) to improve fitness and ventilatory parameters. Primary outcome measures include aerobic, anaerobic, and HIFT measures. Secondary measures include sleep, affect, and mood state questionnaires. Participants will be randomized into one of two groups: with the RMT device and without the RMT device.
This trial is a multi-site, single-arm, phase 2 trial of neoadjuvant combination of enfortumab vedotin and pembrolizumab in cisplatin-eligible patients with high-grade localized/locally advanced cT1-4 N0-1 M0 upper tract urothelial cancer who are deemed eligible for curative-intent surgery (radical nephroureterectomy or distal ureterectomy) followed by adjuvant pembrolizumab.
Repeated sprinting ability is key for athletic performance in a variety of sport settings. Significant degradations in work output (i.e. fatigue) have been shown to develop after just one sprinting bout1. This pilot study aims to investigate the effects that noninvasive transient temperature manipulation has on an individual's ability to perform repeated sprints. The investigators aim to enroll 90 healthy individuals, 18-30 years of age. Participants will be randomized into two groups (Group A, and B). All groups will perform a ten-minute warm-up followed by two minutes of rest. Following the warm-up and rest period, all groups will participate in a series of five sprints, 60 meters in total length with two 180 degree changes in direction. Between sprints, participants will have 10 seconds rest. After the first series of five sprints participants will be given a 2-minute rest interval. Then participants will perform another series of five sprints followed by another 2-minute rest interval. During each rest interval, Group A will utilize a palmar cooling device. Group B will utilize a placebo version of the palmar cooling device. All sprints will be timed. Heart rate recovery will be measured during all rest breaks, and a rating of perceived exertion will be measured at the beginning and end of each resting interval. Delayed onset muscle soreness will be assessed 48 hours post sprinting, utilizing a visual analog scale.
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
Suppose that observers are trying to classify a spot on the skin as normal or abnormal and suppose that the two attributes that are important are the color and shape of the spot. The investigators have found that perceptual decisions of this short are shaped by the prevalence of the target abnormality and by the feedback that observers (Os) receive. If abnormal spots are rare (low prevalence), Os will tend to become more conservative about calling spots abnormal. In this experiment, Os see items defined by color and shape. They are looking for one combination (bumpy green). Bumpy green targets can be common (50% prevalence) or rare (10%). Os in one group will get feedback about their responses based on color. The other group will receive feedback based on shape. The investigators will look for effects of prevalence and of the type of feedback. The goal is to better understand perceptual decisions in settings like clinical evaluation of skin lesions.
