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 study seeks to assess the efficacy of educational messages to correct misperceptions. People hold a number of misperceptions that are relevant to public health, including misperceptions regarding COVID vaccines. Some people incorrectly think the COVID vaccines authorized by FDA are not safe or effective. These misperceptions can reduce adherence to public health recommendations and result in continued spread of COVID. This study will test if humor and different types of framing increase the efficacy of messages to correct misperceptions about FDA's authorized coronavirus vaccine safety and effectiveness. The frames tested will include: framing the vaccine as a way to boost economic recovery and framing the vaccine as a way to increase freedom to choose how to behave. The addition of humor will also be tested. Message efficacy will be measured via improved accuracy of beliefs after being exposed to the message. In other words, participants will be asked how safe and effective FDA authorized COVID vaccines are before seeing a message, then they will see a message about why the COVID vaccines are safe and effective, and then they will again be asked how safe and effective they think the vaccines are. This study will also assess the accuracy of inferential beliefs. This will be accomplished by asking participants questions about other vaccines that either are or are not authorized by FDA. If participants have understood the messages and updated their mental models of how FDA evaluates vaccines, they should be able to infer if other vaccines are safe and effective based on their FDA authorization status. Hypotheses H1: Participants who are exposed to A.) a message with humor, B.) a message with an economic recovery fame, or C.) a message with a freedom frame will be more likely to increase their agreement with the statement that the FDA will only authorize coronavirus vaccines that are safe and effective after message exposure than participants exposed to the control condition. H2: Participants who are exposed to A.) a message with humor, B.) a message with an economic recovery fame, or C.) a message with a freedom frame will agree more strongly with the statement that the FDA approved flu vaccine is safe and effective after message exposure than participants exposed to the control condition. H3. Participants who are exposed to A.) a message with humor, B.) a message with an economic recovery fame, or C.) a message with a freedom frame will agree more strongly with the statement that the ResVax vaccine, which was not approved by the FDA for the treatment of RSV, is a safe and effective after message exposure than participants exposed to the control condition. H4. Participants who are exposed to A.) a message with humor, B.) a message with an economic recovery fame, or C.) a message with a freedom frame will be more likely to increase behavioral intentions to get an FDA authorized COVID vaccine after message exposure than participants exposed to the control condition.
This is a pragmatic, single center, feasibility pilot cluster randomized trial with embedded individual randomization to evaluate implementation strategies to increase the use of evidence-based practices to reduce upper gastrointestinal bleeding risk in patients using combination antithrombotic therapy (including warfarin) and that are managed by the Michigan Medicine anticoagulation monitoring service.
"A Trauma-Informed Intervention for Positive Youth Development and Teacher Wellness in Rural Montana" is intended to help mitigate stressors that may contribute to poor behavioral and mental health in rural Montana teachers. The immediate goals of this study is to promote student health by supporting teacher wellbeing through a remotely-delivered trauma-informed yoga intervention.
The purpose of this study is to determine the static SPF of three sunscreen products (ChapStick Lip Moisturizer [CLM] Original, CLM Mint Flavour and CLM Black Cherry Flavour) using the methodology described in the Food and Drug Administration (FDA) Final Rule (2011).
This was a single ascending dose, randomized, double-blind study assessing the safety, tolerability and pharmacokinetics of STSA-1005 in healthy participants. Four kinds different doses and dose-matched placebo were administered under fasted conditions.
The research proposal will be an 8-week randomized control trial (RCT) to examine the efficacy of an eHealth intervention, namely Healthy Parental Online Education (HOPE), on fruit and vegetable intake and active playtime among toddlers enrolled in early head start programs in Lubbock, Texas. Parents with toddlers ages one to three years will be recruited from Early Head Start centers. Written consent forms will be obtained before baseline data collection. The participants will be then randomly assigned to the intervention or control group. The participants in the intervention group will receive a multi-component online nutrition intervention for eight weeks. While the control group will receive a copy of the booklet that includes the 2020 U.S. Department of Agriculture Dietary Guidelines (USDA) for toddlers and adults. The investigators will measure sociodemographic, parental nutritional knowledge, parental attitude related to healthy eating, parental self-efficacy, parental feeding practices, carotenoids in the skin of both parents and toddlers, three-day food photos, and physical activity and sedentary times of toddlers. This research proposal hypothesizes that there will be significant differences in fruit and vegetable intake and physically active time among toddlers between the intervention and control group from baseline to 3 months. The investigators also hypothesize that there will be significant differences in parental nutrition knowledge, attitude, self-efficacy, and feeding practice between the intervention and control group from baseline to 3 months.
This study involves conducting a telephonic or in person survey regarding parental perception and attitudes about vaccinating the respective "technology dependent" child with the COVID 19 vaccination. "Technology dependent" includes tracheostomy dependence, artificial ventilator dependence and non invasive mechanical ventilation dependence. This population is vulnerable since most patients have underlying lung disease, chronic respiratory failure and require respiratory equipment to assist with breathing. "Technology dependent" patients are particularly vulnerable to respiratory infections and are considered high risk for developing severe COVID 19 illness. Despite this population's high risk for morbidity and mortality from respiratory viral infections, the investigator hypothesize that 50% of the parents are still vaccine hesitant.
The purpose of this study is to asses the efficacy, safety and tolerability of repeat doses of IRL201104 in Adult Participants with Active Eosinophilic Esophagitis (EoE)
Investigating whether delta-beta cross-frequency transcranial alternating current stimulation can increase goal-directed behavior in participants with major depressive disorder and elevated symptoms of anhedonia.
This is a randomised, double-blind, placebo-controlled study to assess the safety and tolerability of multiple ascending doses of BT051 in subjects with moderately to severely active ulcerative colitis. Subjects will be randomised using a 3 active:1 placebo ratio to 3 ascending dose cohorts of 8 subjects and will be dosed daily for 28 days. The 3 initial dose levels will be 200 mg, 800 mg and 3200 mg per day. Progression to the next cohort will be based on the safety and tolerability of the previous cohort.
