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 goal of this interventional study is to determine the impact of high potency THC product use on cognitive function of young adults aged 21-25. The main question it aims to answer is: will cannabis users who switch to less potent THC products demonstrate improved cognitive function compared to baseline? Other questions this study aims to answer include: - Can researchers accurately assess THC consumption among frequent cannabis users? - Can researchers effectively incentivize cannabis users to use less potent THC products? - Do genetic variations in THC metabolism impact urinary THC excretion? - Do genetic variations in THC metabolism impact cognitive performance in cannabis users? - Are quantitative urinary THC values predictive of cognitive impairment? - How can researchers use research findings to inform harm reduction practices for people who use cannabis? Participants will submit blood and urine samples and be incentivized to use less potent THC products.
The main purpose of this study is to see if treating cancer with the magnetic resonance imaging guided adaptive radiotherapy (MRIdian) can control patient's tumor and eliminate the need for surgery used to treat nerves in the spine flattened by pressure (compressed).
The goal of this investigator initiated interventional study is to improve the response to the anticancer treatments (chemotherapy) in people who have previously untreated metastatic pancreas cancer. The main question it aims to answer is: • Do new types of immune-based therapies, called botensilimab, and balstilimab, when given in combination with chemotherapy consisting of nab-paclitaxel + gemcitabine + cisplatin, and oral medications of chloroquine and celecoxib help patients with previously untreated metastatic pancreatic cancer? Participants will be administered two immune-based therapies: - Botensilimab (also referred to as AGEN1811) - Balstilimab (also referred to as AGEN2034) Patients will be evaluated when given in combination with: - Triple chemotherapy (nab-paclitaxel + gemcitabine + cisplatin), plus two oral medications: - chloroquine - celecoxib
This study is intended to assess the incidence and correlation to the development of peri-device leaks (PDLs), device related thrombosis (DRTs) and cerebral vascular accident (CVA)/transient ischemic attacks (TIAs) in association with left atrial appendage contrast flow (LAA-CF). It will be a multi-center, retrospective study. Approximately 100 subject charts will be reviewed.
The goal of this study is to test the contemplative practice is feasible and acceptable among informal dementia caregivers population at all stages.
The purpose of this study is to determine whether Motivating Youth to Reduce Infections, Disconnections, and Emotion dysregulation (MY-RIDE) decreases substance use , to determine whether MY-RIDE increases human immunodeficiency virus (HIV) prevention strategies and to evaluate MY-RIDE effects on willingness to take Pre-Exposure Prophylaxis (PrEP), stress, substance use urge, and use of mental health and substance use services when compared to attention control youth
The goal of this study is to investigate a new treatment for chronic symptoms after concussion or mild traumatic brain injury in people aged 18-65 years old. Chronic symptoms could include dizziness, headache, fatigue, brain fog, memory difficulty, sleep disruption, irritability, or anxiety that occurred or worsened after the injury. These symptoms can interfere with daily functioning, causing difficulty returning to physical activity, work, or school. Previous concussion therapies have not been personalized nor involved direct treatments to the brain itself. The treatment being tested in the present study is a noninvasive, personalized form of brain stimulation, called transcranial magnetic stimulation (TMS). The investigators intend to answer the questions: 1. Does personalized TMS improve brain connectivity after concussion? 2. Does personalized TMS improve avoidance behaviors and chronic concussive symptoms? 3. Do the improvements last up to 2 months post-treatment? 4. Are there predictors of treatment response, or who might respond the best? Participants will undergo 14 total visits to University of California Los Angeles (UCLA): 1. One for the baseline symptom assessments and magnetic resonance imaging (MRI) 2. Ten for TMS administration 3. Three for post-treatment symptom assessments and MRIs Participants will have a 66% chance of being assigned to an active TMS group and 33% chance of being assigned to a sham, or inactive, TMS group. The difference is that the active TMS is more likely to cause functional changes in the brain than the inactive TMS.
The overall objective of this proposal is to conduct a randomized-controlled study to determine whether treatment with dehydrated human amnion/chorion membrane (dHACMs) allografts can improve NAC viability in patients undergoing nipple sparing mastectomy (NSM). dHACM allografts are commercially available tissue membranes with biocompatible extracellular matrix and growth factors that have been shown to improve wound healing in patients with chronic and lower extremity wounds. To date, no study has evaluated the impact of dHACMs on NAC preservation following NSM. Investigators hypothesize that subareolar surgical implantation of dHACM allografts at time of NSM will reduce NAC necrosis and improve viability.
The current study will determine protein nutritional status (MPS and WBPB) in response to military-relevant sleep loss, and whether an even protein nutrition distribution during recovery optimally supports MPS and WBPB. Adults (n=20) will complete a 7d sleep satiated phase (~7-9h target/d), a 4d military-relevant sleep restriction phase (~4h /d), and a 3d recovery phase (~7-9h target/d) in a randomized, parallel design. During recovery, volunteers will consume 1.6 g protein/kg/d as an even (~0.4/0.4/0.4/0.4 g/kg) or skewed (~0.11/0.27/1.15/0.07 g/kg) distribution. Sleep will be monitored throughout the study using wrist actigraphy and diaries. During each phase, integrated daily MPS will be estimated using ingested deuterium oxide, salivary and blood sampling, and muscle biopsies, while WBPB will be estimated using ingested 15-N alanine and urine collections. At the end of each phase, metabolic testing will be used to assess the effects of sleep loss on substrate utilization and include consuming a carbohydrate beverage, serial blood draws, indirect calorimetry, and steady-state aerobic exercise. The knowledge products derived from the proposed effort will be informative to next generation ration development and support military-specific recovery nutrition guidance following operations involving sleep loss.
The aim of this study is to test the hypothesis that sotagliflozin (SGLT1/2 inhibitor) and ambrisentan (ERA) combination therapy augments nephroprotection and mitigates fluid retention and ketogenesis in people with T1D through complementary and synergistic mechanisms of actions.
