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 purpose of this research study is to investigate how personality traits and neuroendocrine systems relate to decision-making patterns in individuals 18-45 years old. The main question it aims to answer is how neuroendocrine activity impacts decision-making. This study has two components. First, there will be an online session that participants complete to consent into the study, complete self-report surveys and a cognitive assessment, and confirm their eligibility for the second part of the study. If eligible to continue, participants will complete one in-person experiment session, during which they will complete self-report measures and a decision-making task. During the in-person session, participants will be randomly assigned (like flipping a coin) to ingest either a placebo (non-active) or the combination of hydrocortisone and yohimbine.
This study employed secondary database analysis of the Adelphi Dry Eye Disease (DED) Disease Specific Programme™ (DSP™), a templatized cross-sectional survey with retrospective data collection that is administered by Adelphi to a convenience sample of patients diagnosed with DED, and their consulting physicians in the United States. In addition to the survey data, the DED DSP also included recorded medical history data as reported by physicians (optometrists, ophthalmologists or refractive surgeons).
This is a Phase 1/2 Study to Assess the Safety and Efficacy of OCU410 for Geographic Atrophy Secondary to Dry Age-Related Macular Degeneration (AMD). This is a multicenter study, which will be conducted in two phases and will enroll up to a total of 63 subjects.
This research study seeks to determine the effects of an enzyme in the human body called NADPH oxidase (NOX) on blood flow. In addition, the study will investigate the benefits of creatine monohydrate, a common sports performance supplement, on blood food and vessel function. Participants will undergo two study arms, one in which they consume a high carbohydrate meal pre- and post-creatine monohydrate supplementation and one in which they will consume a high carbohydrate meal pre- and post-placebo supplementation. Blood flow and endothelial function will be assessed before and for 4 hours following the consumption of a high-carbohydrate meal pre and post-supplementation (creatine monohydrate and placebo).
Purpose: To evaluate preimplantation genetic testing counseling interventions on patients undergoing in vitro fertilization treatment. Preimplantation genetic testing for aneuploidy (PGT) allows patients undergoing in vitro fertilization (IVF) to screen embryos for genetic disorders. Preimplantation genetic testing for aneuploidy (PGT-A) is the testing most commonly ordered, and it screens for whole chromosome and large partial chromosome duplications or deletions. Currently, patient counseling varies based on the clinic, ranging from appointments to group seminars with a genetic counselor (GC), geneticist or reproductive endocrinology and infertility (REI) physicians for education regarding PGT. Patient knowledge regarding PGT has been varied with some studies indicating sufficient knowledge, while other studies have shown a potential lack of knowledge. One study indicated a third of patients had regret regarding their decision of whether or not to use PGT-A during IVF and another study indicated patients who choose to undergo PGT did so for reasons that were not evidence based. Additionally, educational materials have been illustrated to be inconsistent and with inappropriate literacy in regards to PGT counseling. One study has shown the potential of improvement with written intervention amongst providers and patients in regards to PGT related to a single genetic condition. The investigators hope to assess the efficacy of PGT-A educational and counseling interventions on patients undergoing IVF.
This is a Phase IIa, Randomized, Double-blind, Placebo-controlled, multi-center Proof-of-Concept (POC) Trial in subjects with severe Alopecia Areata.
The investigators will pilot test a clinician-led intervention to improve medication adherence in general rheumatology clinic across a spectrum of rheumatic diseases. The study will assess feasibility, acceptability, and fidelity, and explore signal for improved medication adherence.
The goal of this clinical trial is to assess the efficacy of DB-1303/BNT323 compared with investigator's choice chemotherapy in terms of progression-free survival (PFS) by blinded independent central review (BICR) in the HR+, HER2-low (immunohistochemistry [IHC]2+/in situ hybridization [ISH]- and IHC 1+) population.
The purpose of this study is to determine the feasibility and effects of an adapted Exercising Together, a partnered resistance training program, on the physical and mental health of prostate cancer survivors and their informal caregiver. The Exercising Together program is designed to promote teamwork during supervised group exercise classes delivered remotely through videoconferencing software. The intervention period will be 3-months with a 3-month follow-up.
Suicide is the second leading cause of death among young people aged 12-17 years in the United States, yet many youth at risk for suicide are not identified or go untreated. Stepped care approaches have been shown to be effective at reducing suicide risk in clinical settings, including primary care. The goal of this hybrid I stepped wedge effectiveness-implementation study is to test the effectiveness of a population-based quality improvement (QI) intervention, entitled STARRS-PC (Stepped Approach to Reducing Risk of Suicide in Primary Care) compared to treatment as usual (TAU), in reducing the risk of suicidal behavior among youth in the pediatric primary care setting. STARRS-PC implements a clinical pathway for youth at elevated risk for suicide in pediatric primary care clinics. Clinical pathways are tools used by health professionals to guide evidence-informed practice. The STARRS-PC pathway consists of three evidence-based suicide clinical care processes: risk detection, assessment and triage, and, if needed, follow-up transitional care. STARRS-PC is guided by the Practical, Robust Implementation, and Sustainability Model (PRISM), which allows for the study of factors that influence effective implementation of the suicide prevention clinical pathway and is focused on scalability. The main questions the study aims to answer are: - Will STARRS-PC be more effective than TAU at reducing the rate of suicide attempt at 12 months post-baseline (primary outcome)? - Will STARRS-PC be more effective than TAU at reducing suicidal ideation and non-suicidal self-injury, and improving family satisfaction at 12 months post-baseline (secondary outcomes)? - What are the barriers and facilitators of effective implementation and sustainability of STARRS-PC?
