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 observational study is to learn about the effect improved access to culturally-appropriate fruits/vegetables has on cardiometabolic markers, specifically systolic blood pressure and markers of adiposity in immigrant Hispanic/Latinx individuals with hypertension and obesity. The secondary aim is to determine compliance to the increased F/V intake recommended by the Dietary Approaches to Stop Hypertension (DASH) Diet by assessing changes in skin carotenoid status. The main question it aims to answer is whether consuming 8-10 servings of culturally-appropriate, carotenoid-containing F/V daily for 4 weeks to meet the requirements of the DASH Diet supported by diet and lifestyle education will result in reductions in systolic BP and decreased markers of adiposity (body weight, Body Mass Index, and waist circumference).
The purpose of the study is to examine the implementation strategy, in terms of feasibility and the possible benefits, of a free online Zoom t'ai chi and qigong gentle movement and meditation program to reduce back pain and improve sleep and quality of life among those with chronic back pain. The primary objective of this study is to examine whether a safe and moderate online t'ai chi and qigong exercise program, offered without cost to individuals with chronic back pain, improves pain levels, sleep, and quality of life; The secondary objective is to explore whether improvements in pain levels are different among smokers and those with unhealthy BMI than among others.
The goal of this clinical trial is to compare two different types of activities in improving physical fitness in older adults. The main question it aims to answer is whether a person completing a large-scaled art project has similar physical improvements as a person completing a more traditional exercise program. Participants will be asked to either stand for up to an hour while completing a painting across a large canvas or stand for up to an hour while doing body weight exercises. Researchers will compare the painting group to the exercise group to see if physical improvements are the same or different.
The goal of this observational study was to better understand the impact of increased plasma volume on later exercise in hypoxia. Investigators examined young, healthy, males who regularly participated in aerobic exercise. Investigators first measured participant's response to exercise in hypoxia (simulated ~7,500 feet above sea level). The investigators then had participants either 1) undergo 1 bout of high intensity interval exercise or 2) undergo 1 bout of moderate, continuous exercise. 48 hours after the exercise, participants were again examined in hypoxia.
This study used a randomized controlled trial to evaluate whether Healium (designed to target preference elicitation) is as efficacious as Healing Choices (a comprehensive education and decision tool) in improving outcomes for decision-making and emotional quality of life.
This prospective clinical performance study is a non-interventional, multi-center study to evaluate the assay performance of the COVID-19 test using upper respiratory specimens. Prospectively collected nasopharyngeal and anterior nasal swabs will be collected from each participant recruited in the study.
The goal of this clinical trial is to test in three samples, including sample 1: lay people without reported depression symptoms, sample 2: lay people with reported depression symptoms and sample 3: mental health clinicians. The main questions it aims to answer are: 1) do each of these populations show a bias against psychotherapy wherein they judge psychotherapy to be less effective, relative to baseline ratings, when a mental illness (i.e., depression) is attributed to biological factors, 2) whether an intervention emphasizing the neurobiological effects of psychotherapy can remove this bias against psychotherapy for biologically-caused mental disorders, and 3) whether this intervention is more effective compared to an active control intervention that emphasizes the effectiveness of psychotherapy, but not its neurobiological effects. Participants will - rate the effectiveness of psychotherapy for depression before and after learning about the biological causes of depression - be assigned to one of three conditions: 1) an intervention condition where participants will receive a brief reading passage (approximately 126 words in length) providing psychoeducation about how psychotherapy changes the brain of an individual with depression, or 2) an active control condition where participants will receive a reading passage (approximately 115 words) emphasizing the effectiveness of psychotherapy, or 3) a control condition where they will receive no additional materials - as a secondary outcome, participants will also rate the effectiveness of medication for depression, before and after learning about the biological causes of depression
Primary care visits are a key aspect of clinical care focused on helping patients to close care gaps related to preventive care such as vaccination, diabetes testing, statin therapy and cancer screening. However, less than 50% of care gaps are closed during these visits and new approaches are needed to prime patients for a discussion during these visits. In this study, the study team will evaluate a health system initiative that uses text messaging to patients in days preceding a primary care visit to prime patients to be amenable to ordering of vaccination, diabetes testing, cancer screening, and statin prescribing.
The purpose of the study is to understand the effects and safety of PF-07817883 treatment. The study wants to know how PF-07817883 treatment lowers the level of the virus that causes COVID 19. To understand that samples are collected from adult participants who have the symptoms of COVID 19 but are not hospitalized. The study is seeking for participants who: - are 18 years of age or older at the time of entering the study. - have a positive rapid antigen test within 48 hours before entering the study. Rapid antigen test is a test done to confirm the presence of a specific virus in the body. - have onset of signs or symptoms of COVID-19 within 5 days before entering the study. - have at least 1 of the specified signs or symptoms of COVID-19 present on the day of entering the study. Around 228 participants with a confirmed case of COVID 19 are planned to be taken into the study. Participants will be randomly grouped to receive PF-07817883. Three groups will receive 100, 300, 600mg of PF-07817883 and one of the groups will receive placebo (a pill that doesn't have any medicines) orally every 12 hours for 5 days. The study is going to last up to 5 weeks. This includes the initial period of selecting participants, participants receiving the medicine or the placebo and then a 4-week follow-up period after giving the participants the last medicine. The study team will monitor how each participant is doing with the study treatment during the study.
The goal of this clinical trial is to evaluate the potential effects of photobiomodulation when used with topical disinfectants in the anterior nares of healthy adults. Over a three week period, participants will have their anterior nares swabbed with methylene blue, chlorhexidine gluconate, or a combination of the two followed by 4 minutes of non-thermal red light treatment. The fourth week of consist of only red light treatment. Culture samples of the subjects nasal microbiome will be taken prior to treatment, immediately after treatment, 4-, 8-, 24-, and 48 hours after treatment.
