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 is an open-label, parallel-group study to evaluate the safety and efficacy of ropanicant in participants with moderate to severe Major Depressive Disorder (MDD).
This study aims to emulate a hypothetical target pragmatic multi-center, non-blinded trial of adult inpatients in the PINC AITM dataset with B-lactam treated culture confirmed monomicrobial invasive Group A streptococcus (GAS) between the years 2015-2021
This is a virtual single-group study that will last three menstrual cycles (approximately 12 weeks). During the first menstrual cycle, participants will take the supplement as needed (pro re nata) when they feel symptoms of PMS, such as cramping or bloating. For the second and third menstrual cycles, Participants will take 2 capsules per day with water for 1 week, starting 4 days before their menstrual cycle and finishing on Day 3 of their cycle. Questionnaires will be completed at the following time points: - Baseline - Day 7 of their first cycle during the trial (After using the product PRN during their period) - 4 days before their second period during the trial (After using the product PRN for the previous month) - Day 3 of their second period during the trial (After using the product for 7 days straight) - Day 3 of their third period of the trial (After using the product for 7 days straight)
This is a virtual single-group study that will last 12 weeks. Participants will take 1 capsule every day, with water. Questionnaires will be completed at baseline, 2 weeks, 4 weeks, and 12 weeks.
This is a virtual single group study that will last 12 weeks. Participants will take 1 scoop of the female hormone balance supplement, and mix it with their drink of choice every morning. Questionnaires will be completed at baseline, 1 week, 2 weeks, 4 weeks, and 12 weeks
Gastrointestinal infections cause significant morbidity in the form of acute diarrheal illness in the United States (US) and among travelers to low- and middle-income countries (LMICs). One approach is to use passive protection (antibodies) to prevent infection. The purpose of this study are to assess the safety and tolerability of serum-derived bovine immunoglobulins in healthy adult subjects when orally administered and to estimate protective efficacy of those preparations against moderate-severe diarrhea upon challenge with Campylobacter C. jejuni strain CG8421.
This virtual single-arm trial will last 12 weeks. Participants will take the drops daily and complete questionnaires at Baseline, Week 4, Week 8, and Week 12. Urine pH measurements will be taken at Baseline, Week 4, Week 8, and Week 12 using pH test strips.
This is a prospective cohort study of outpatient adults with chronic abdominal wall pain receiving abdominal wall injections, as part of their usual care, with lidocaine. Subjects will be recruited at the outpatient gastroenterology clinic at OHSU.
This project is intended to collect data using standard clinical tests and psychophysics to quantify the effect of visual cortical damage on the structure of the residual visual system, visual perception, spatial awareness, and brain function. The investigators will also assess the effect of intensive visual retraining on the residual visual system, processing of visual information and the use of such information in real-world situations following damage. This research is intended to improve our understanding of the consequences of permanent visual system damage in humans, of methods that can be used to reverse visual loss, and of brain mechanisms by which visual recovery is achieved.
The COVID-19 pandemic has led to a mis/disinformation ecosystem that promotes divergent views of vaccine efficacy, as well as the legitimacy of science and medicine. Individuals are confronted with vaccine-related information from a multitude of sources, posing a challenge to identifying inaccurate information. COVID-19 vaccine uptake is lower among people with anxiety and depression than in the general population, due in part to higher levels of vaccine hesitancy. The prevalence of anxiety and depressive symptoms among US adults increased significantly during the COVID pandemic and has remained elevated. Interventions capable of mitigating the impact of vaccine hesitancy and mis/disinformation among undervaccinated people with anxiety or depression are therefore an urgent priority. Emerging evidence suggests that reasons for vaccine hesitancy and the impact of conventional vaccination messaging differ between those with and without mental health symptoms. There may also be added challenges overcoming logistical barriers to vaccination for people with anxiety or depressive symptoms. The investigators aim to determine the effectiveness of two different brief digital intervention strategies compared with conventional public health messaging for increasing vaccine uptake in undervaccinated adults with and without anxiety or depressive symptoms. Attitudinal inoculation is a brief, scalable strategy that leverages the power of narrative, values, and emotion to strengthen resistance to mis/disinformation and reduce hesitancy. Though this approach has been shown to decrease COVID-19 vaccine hesitancy among US adults, the extent to which this approach increases COVID-19 vaccination remains unknown. Cognitive-behavioral therapy (CBT) is an evidence-based intervention for anxiety and depression. However, the efficacy of incorporating CBT-informed messaging in a vaccine promotion intervention has not been tested. The investigators hypothesize that both attitudinal inoculation and CBT-style communication will be more effective than conventional public health messaging to increase COVID-19 vaccination. The investigators also hypothesize that the CBT-informed intervention will be more effective than the attitudinal inoculation intervention for increasing COVID-19 vaccination among participants with symptoms of anxiety or depression.
