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 investigate an evidence-based, manualized, behavioral health intervention, Cognitive Behavioral Therapy for Insomnia (CBT-I), in individuals with primary brain tumors (PBT) and insomnia. Our project will assess the feasibility and acceptability of recruitment, enrollment, data collection procedures, and retention of individuals with PBT and insomnia in the behavioral health intervention, CBT-I, and investigate the potential benefits of CBT-I within this at-risk and understudied population. In the long term, the goals are to expand treatment options for neuro-oncology patients and improve their mission readiness and overall wellbeing.
This study seeks to compare the effectiveness of two Patient Navigation models of care to evaluate the proportion who initiate PrEP/ART and substance use/substance use disorder (SU/SUD) treatment. A standardized Patient Navigation (PN) arm will be compared with a shared decision-making model in the form of Patient Choice (PC) through the offer of a menu of existing community-based health service delivery options. This design will offer providers, correctional and public health authorities, payers and policy makers' timely and relevant data to assess the effectiveness of Patient Navigation and Patient Choice models of care as potentially useful re-entry and relapse prevention treatment options.
The goal of the study is to assess how tirzepatide impacts bodyweight and cardiovascular risk factors when used in conjunction with healthy nutrition and physical activity in adolescents with obesity and multiple weight related comorbidities. The study will last approximately 76 weeks and may include up to 23 visits.
The objective of this study is to assess the implementation process for and the effectiveness of a quality improvement (QI) strategy to increase shared decision-making around anesthesia options for hip fracture surgery at 6 US hospitals. The QI strategy is to be facilitated by a clinician-administered 1-page bedside conversation aid designed to improve the quality of physician-patient communication, paired with brief clinician training. The evaluation will occur via a stepped wedge, cluster randomized trial to be carried out over a period of 27 months.
Vaginal infections are a common gynecologic issue and may cause significant symptoms and discomfort for individuals. Point of care tests are used to diagnose infections in the office, with an advantage of quick diagnosis and treatment. Examples of point of care tests are urine pregnancy, rapid strep and COVID-19 tests. This study will enroll persons with vaginal complaints and compare diagnosis and treatment based on usual care to diagnosis and treatment using a Food and Drug Administration-approved point of care test for the diagnosis of vaginitis. The study is being done to better understand diagnosis, treatment, and satisfaction using point of care tests compared to usual care. Participants will be randomized to one of two study arms: Arm 1: the healthcare provider will perform their usual evaluation and tests to make the diagnosis and provide treatment, as needed. Arm 2: the provider will be asked to use the results of the point-of-care test being used in the study to make the diagnosis and provide treatment, as needed. Regardless of arm, all diagnoses and treatment will be provided through the healthcare provider. All participants will be contacted 2 weeks later to answer a questionnaire related to diagnosis, treatment, current symptoms, and satisfaction with their visit. Medical records related to vaginal complaints, up to 30 days from enrollment, will be reviewed by the study team to obtain information on symptoms, tests performed, results, and treatments prescribed.
The goal of this clinical trial is to measure how well different formulations of vitamin A (VA) are absorbed by the body when they are added to bouillon (broth) as vitamin A palmitate (VAP). Fortifying bouillon cubes with VA is one potential approach to addressing VA deficiency, which is a major public health issue in many low- and lower-income countries. The main question this study aims to answer is to compare the amount of VA that is absorbed by the body from three different VAP formulations that are added to bouillon. Participants will consume different formulations of VA and have multiple blood collections.
The goal of this observational study is to determine phenotypic, transcriptional, and epigenetic underpinnings of renal allograft rejection in renal transplant rejection. The main questions it aims to answer are: - To determine the phenotype, frequency, location, and the inter-cellular interactions between the cells that constitute intra-graft inflammatory infiltrate in acute ejection. - To determine the phenotype, frequency, location, and the inter-cellular interactions between the cells that constitute intra-graft inflammatory infiltrate in recurrent/recalcitrant rejection vs. rejection that resolves with therapy. - To generate a scRNA sequencing (scRNAseq) map of the intra-graft immune cells and the renal parenchymal cells and compare the transcriptional and epigenetic changes within these cells in recurrent/recalcitrant rejection vs. rejection that resolves with therapy. - To determine phenotypic changes associated with chronic rejection. Participants will be asked to provide the following research specimens: - Renal biopsy specimens at the following timepoints: day of transplantation (pre-implantation and post-perfusion); routine protocol biopsies at 3 months and 12 months; and clinically indicated for-cause biopsies at any timepoint from time-0 to 1-yr post-transplantation. The 1st research core will be used for routine histopathological examination and left over tissue from this core will be used for deep phenotyping using multiparameter immunophenotyping, and digital spatial profiling. The second research core will be used for extraction of cells and nuclei for scRNAseq and snATACseq. - Blood samples will be processed to obtain plasma (for cytokine, chemokine and DSA measurements) and PBMC (for deep phenotyping and molecular analyses). For each collection timepoint, up to 75 mL (about 5 tablespoons) will be collected. - Prospective clinical data and outcomes will be collected from participant medical records. - Follow-Up Period: For-cause biopsies from 1-yr to 5-yr post-transplantation (by the transplant nephrologist): no additional cores will be obtained for research from these biopsies. The left-over tissue from the clinically indicated biopsy cores will be analyzed by deep phenotyping and digital spatial profiling. Blood samples will be processed to obtain plasma (for cytokine, chemokine and DSA measurements) and PBMC (for deep phenotyping and molecular analyses).
The STRIVE study is the first national randomized trial to focus on improving well-being, access to surgical care and other health outcomes for transgender and nonbinary (referred to as trans) people seeking genital gender-affirming surgery (GGAS). Trans people have gender identities that are different from the sex they were assigned at birth. Due to discrimination based on their gender identity in settings such as schools, the workplace, housing and health care, trans people face much higher rates of distress as well as poorer health and quality of life. Trans people are often unable to access necessary surgeries and hormone therapy to help align their bodies with their gender identities due to a lack of trained medical providers and limited insurance coverage for gender-affirming care. The most common GGAS that trans people seek is vaginoplasty, which is the surgical creation of vaginal anatomy. Because of the high demand for this surgery and limited number of medical centers that offer it, trans people face lengthy wait times and complicated health system processes, increasing stress, negative mental health effects and social isolation. Social and peer-support interventions have been shown to decrease isolation and improve health. Social support during the GGAS process was also identified by the Transgender and Non-Binary Surgery - Allied Research Collective (TRANS-ARC) as the top research priority. Due to limited information on this topic, the STRIVE study was developed to meet this need. The research team's goals are to: - Compare the effectiveness of two approaches to presurgical preparation for vaginoplasty: a virtual group-based peer support intervention led by trans peers who have had GGAS, or usual care delivered by gender-affirming surgical teams, enhanced with patient education materials. - Determine if the intervention improves meeting presurgical criteria for vaginoplasty. - Evaluate if patients, peer supporters and healthcare staff find the intervention acceptable. The research team will conduct a pragmatic randomized controlled trial, meaning participants will be assigned by chance to one of two groups: peer-support group or usual care enhanced with written and web-based education materials. This study is pragmatic because it is happening under real-life conditions to understand if the intervention will work in practice. The research team will work with five academic gender-affirming surgery programs across the country to recruit and enroll 260 trans adults ages 18 and older who are seeking vaginoplasty. Participants assigned to the peer support group will receive the intervention virtually over the course of three months, facilitated by peer facilitators from Trans Lifeline. The usual care group will receive education from their gender-affirming surgical team, with in-depth materials that cover the same topics as the virtual course. The primary outcome to be measures at six months is coping self-efficacy, reported by patients, using a survey which assesses perceived ability to deal with stressors. The research team will explore additional outcomes at 12 months, including meeting GGAS presurgical criteria and other outcomes deemed important to trans community partners, surgeons and other gender-affirming providers (e.g., psychological stress, social support, resilience, quality of life, presurgical knowledge, surgical delays and cancellations). Postsurgical outcomes, including surgical satisfaction and other related outcomes, will be measured at 24 months. Finally, the team will conduct in-depth interviews with participants who undergo the intervention to understand their experiences at the beginning of the study and after six months. Researchers will also interview peer supporters and clinicians to understand how to improve and implement the support intervention more broadly. In designing this study, the research team worked closely with trans community members and patients, health services and policy researchers, gender-affirming surgeons, advocates, gender program administrators and representatives from social support organizations. Collaboration with and input from the trans community during the conduct of this study will be critical to ensure that the STRIVE study is patient centered. Results from this study will be shared in multiple forms, including clinical guideline recommendations, policy briefs, patient-centered reports, web-based information and summaries for clinicians and researchers. Trans people seeking gender-affirming surgery can use the study findings to understand options for social support to improve quality of life and health outcomes. Clinicians, gender program administrators, health insurance companies and health policy advisors can use the findings from this study to better support and prepare patients who are seeking gender-affirming surgery.
This observational study aims to look at the connections between kidney stones, insulin resistance, and inflammation. The researchers hypothesize that people who form calcium kidney stones and have insulin resistance may have higher levels of inflammation because they have more visceral fat (fat around the abdominal organs). The study will recruit 20 people who have had calcium kidney stones but don't have diabetes, and 20 healthy people who haven't had kidney stones. All the participants will come to the research center at the University of Chicago Medicine. Participants will have a dual-energy X-ray absorptiometry (DEXA) scan to measure their visceral fat, and give blood and urine samples. The blood will be tested for insulin resistance, inflammatory markers, and other metabolic factors. The urine will be analyzed for substances that increase kidney stone risk. The main goal is to see if the kidney stone formers with insulin resistance have more visceral fat compared to those without insulin resistance and the healthy participants. The researchers will also compare inflammatory marker levels between groups, and look at how visceral fat, inflammatory markers, insulin resistance, and urine stone risk factors are related. The findings may help explain how kidney stones are connected to metabolic conditions like diabetes and cardiovascular disease. Researchers hope this information will help identify stone formers at risk early and develop preventive treatments in the future.
