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 study aims to evaluate the metabolizable energy of the typical American diet with and without the inclusion of fiber. We hypothesize that including fiber in the diet will decrease the metabolizable energy of the diet resulting in more nutrient loss into the feces and urine.
This is a randomized, double-blind, placebo-controlled study to investigate if Travelan® protects healthy adult volunteers from moderate-to-severe diarrhea upon challenge with Enterotoxigenic Escherichia coli (ETEC) strain H10407.
This is an observational cohort study to evaluate real-world vaccine effectiveness and durability of Moderna COVID-19 vaccine among a diverse population at Kaiser Permanente Southern California (KPSC). The primary objective of this study is to evaluate the vaccine effectiveness (VE) of receipt of Moderna COVID-19 vaccine in preventing SARS-CoV-2 infection and severe COVID-19 disease. SARS-CoV-2 infection will be defined as a positive antigen test result as well as a positive molecular diagnostic test among symptomatic or asymptomatic participants or a COVID-19 diagnosis code. Severe COVID-19 disease will be defined as COVID-19 hospitalization or mortality.
The purpose of this research is to assess mucosal immune function responses in the gastrointestinal (GI) tract to twice-daily yogurt consumption. Previous research has shown that dairy yogurt intake can benefit gastrointestinal health. The current study will determine whether a dietary intervention with dairy yogurt will improve mucosal immunity and the gut microbiome.
For this project the broad research objective is to evaluate the effectiveness of an enhanced digital wellbeing program in improving well-being, depression, anxiety, stress, resilience, and job satisfaction of physicians. The intent of the investigators is that this will enable a proactive culture of well-being and mental health support for the broader healthcare workforce during the multiple phases of the pandemic. The investigator's approach evaluates existing digital models which can be executed in a timely fashion and rapidly scaled for use across other health systems. Aim 1: Conduct interviews of URM and women physicians to identify barriers and facilitators to accessing and receiving digital well-being, mental health, and culturally sensitive support resources. Aim 2: Through a randomized controlled trial (RCT) investigate the immediate and long-term effect of a comprehensive well-being focused intervention (push text messaging, resource support, semi-facilitated peer groups hosted by Cobalt) vs. usual care on well-being, depression, anxiety, stress, resilience, and job satisfaction of physicians practicing in the era of COVID.
This is a multi-center series assessment with a planned accrual of 70 patients with diagnosed symptomatic primary GSV insufficiency. Patients will be consented at a Pre-Study Visit and evaluated for eligibility and for baseline characteristics of the disease. Patients will receive treatment with Sonovein for the targeted segments of GSV. At follow-up visits at 7 days (1 to 10 days), 3 months (+/- 20 days), 6 months (+/- 25 days), and 12 months (+/- 30 days) changes in veins and flow characteristics will be evaluated by ultrasound, and patient well-being, including pain which will be evaluated by patient-reported VAS evaluations. Continued follow-up for a total of 12 months will be completed prior to subject study exit. Adverse events (AE) will be assessed at every study visit following HIFU treatment.
The aim of this study is to assess the impact of an in-person multi-component Advanced Cooking Education (ACE) 4-H after school program. The ACE Program consists of mindfulness, nutrition education, cooking labs, and professional development activities.
The actual quality of Red Blood Cells (RBCs) salvaged during spinal deformity surgery has never been rigorously evaluated. To characterize the usefulness of intraoperatively salvaged RBCs in spinal deformity surgery. The study team hopes to answer the following questions: 1) What is the quality of RBCs salvaged during spine surgery? 2) Does intraoperatively transfused RBC salvage impact clinical outcomes?
This is a Phase 2/3, randomized, double-blind study to evaluate the safety and immunogenicity of different booster dose levels of the monovalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle (SARS-CoV-2 rS) vaccines with Matrix-M™ adjuvant (NVX-CoV2373 [prototype Wuhan vaccine with Matrix-M adjuvant] or NVX-CoV2601 [Omicron XBB.1.5 subvariant vaccine with Matrix-M adjuvant]).
The primary objective of this study is to understand the efficacy of S-309309 on the body weight of obese adults.
