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.
This observational study aims to assess recovery of the immune system and immunity to vaccine-preventable diseases in children and adolescents who recently completed treatment for acute lymphoblastic leukemia (ALL). Several children's hospitals in the United States are participating in the study, which will enroll approximately 75 pediatric participants. The study is intended to determine the rate of infection after leukemia treatment and to inform future studies and recommendations about whether children and adolescents who have leukemia should receive additional vaccine doses or boosters after treatment.
The purpose of this research is to learn about the difference in the endotracheal intubation condition (ease of using a device to view vocal cords, position of vocal cords, and patient's reaction to endotracheal tube insertion) and determining the appropriate time to perform the intubation.
This study is investigating the potential effects of a high-intensity home-exercise program among children with cerebral palsy. The program includes rhythmic movements to music that are adapted for wheelchair uses and age-appropriate themes. This project has the potential to address a large knowledge gap in the extant literature, because there are no widely accessible, evidence-based, enjoyable, and age-appropriate modalities for improving cardiovascular fitness or cardiometabolic health among children with disabilities who have mobility disabilities.
A prospective monitoring study for those individuals treated with Paxlovid
Young adults aged 18-26 engage in a number of behaviors that increase their risk of developing cancer later in life including sedentary lifestyles, unhealthy eating, nicotine produce us, heavy drinking of alcohol, increased UV exposure, and incomplete uptake of HPV vaccination. A multi-risk factor campaign will be developed to reduce these cancer risk behaviors and delivered to young adults over social media, a popular channel that can reach nearly all young adults. The campaign will be evaluated for effectiveness in a rigorous randomized trial with measures of moderate to vigorous physical activity, healthy eating patterns, nicotine product use, alcohol intake, sunburn prevalence, and HPV vaccination uptake.
Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are severe clinical conditions that, despite advances in therapeutics over the past 20 years, lead to serious morbidity and mortality. Guidelines on the diagnosis and treatment of pulmonary hypertension (PH) recommend the use of a multiparametric risk stratification tool to determine severity of disease, which should guide initial therapy and therapy modulation. This multiparametric risk stratification schema includes objective assessment of exercise capacity, right ventricular function and hemodynamic parameters in order to classify patients into severity categories. Cardiac index (CI) and right atrial pressure (RAP), measured via right heart catheterization (RHC), are the hemodynamic parameters used in risk assessment of PH. Arguably, stroke volume index (SVI) is the most important hemodynamic parameter for assessment of PH severity and there is currently no validated method for noninvasive measurement of cardiac output (CO), CI or SVI. Currently, a major obstacle in the field is that hemodynamic measurements are not obtained on a regular basis in the risk assessment and therapy modulation of patients with PAH and CTEPH. If a noninvasive method of hemodynamic measurement could be correlated with other objective measurements of risk assessment, it could become an invaluable tool in therapy initiation and modulation in the ambulatory setting. This is a single center study to evaluate the use of non-invasive measurement of CO and stroke volume to assess risk and response to treatment in patients with PAH and non- operable CTEPH. We anticipate to enroll a total of 100 subjects at Ronald Reagan UCLA Medical Center. A maximum of 10 hour in total for the study including the consent process, pre-procedure care, RHC procedure, and follow up visit. The initial visit will be approximately 4 hours with the RHC procedure itself will only be 20 minutes. Each follow up visit will be 1.5 hour. Patients with known or suspected PAH or CTEPH will undergo a RHC as part of his or her standard of care. Three techniques of CO measurement will be performed sequentially at the time of the RHC. The device that will be used is the Edwards ClearSight system and EV1000 clinical platform, a device that measures NIBP. Patients will be followed over the period of 1 year every 3 months to obtain serial measurements for six-minute walk distance (6MWD), World Health Organization (WHO)/New York Heart Association Functional Class (FC), B-type natriuretic peptide (BNP) or N-terminal-pro hormone BNP (NT-proBNP), and non-invasive hemodynamic measurements. Additional visits will be scheduled to obtain the serial measurements one month prior and one month following if a patient is initiating or changing PH-specific therapy. As this is a study looking at the feasibility of non-invasive measurement of cardiac output and stroke volume for risk assessment and response to therapy in pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH), study personnel performing the study procedures will not be blinded to the clinical diagnosis and the management of the subject.
The primary study objective is to evaluate a cementless partial knee system that has a modular 3-D printed porous metal tibial component and a cemented partial knee system. The hypothesis is that at minimum 2-year follow-up, fixed bearing medial partial knee replacements using cementless and cemented fixation will demonstrate no differences in clinical outcome.
The current project uses a web-based program called the Expectancy Challenge Alcohol Literacy Curriculum (ECALC) to reduce alcohol use and associated harms among college students. Participants complete the interactive program in 50 minutes, and then provide daily, real-time data on expectancies and alcohol use for 3 weeks after intervention, and again for one week at 13 and 25 weeks after intervention. One group will also receive biweekly boosters delivered via smart phone to assess their impact on intervention decay over time. It is hypothesized that ECALC effects may decay over time, and that biweekly boosters will prevent this decay. Access to the ECALC is available on request from the principal investigator.
This is a long-term, 3-year, follow-up study for patients completing the KS-GIG-001-01 Study
The goal of this clinical trial is to study the effect of peppermint oil in in children with bladder and bowel dysfunction. The main question it aims to answer is: Does peppermint oil improve symptoms of bladder and bowel dysfunction among children? Participants will: - Be provided peppermint oil capsules to be taken 3 times daily for 8 weeks. - At baseline and at a follow-up visit (8 weeks later), participants will be asked to complete the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire. Researchers will compare baseline and follow-up questionnaire data for each participant to determine if there is improvement in symptoms of bladder and bowel dysfunction.
