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 study is to assess Anterior Cruciate Ligament (ACL) healing through analyzing clinical, radiographic, functional and patient-reported outcomes following ACL reconstruction with quadriceps graft with and without internal bracing.
This project will be the first to examine the efficacy of a text messaging intervention designed to recruit first-time fathers-to-be using social media across the U.S. to become involved during pregnancy through two months of postnatal age to support infant, mother, and father well-being.
The goal of this interventional study is to compare the baseline neural mechanisms and parenting in depressed and non-depressed children and to examine baseline neural mechanisms and parenting as predictors of Family-Focused Treatment for Childhood-Depression (FFT-CD) outcomes. The main questions it aims to answer are: - What are differences between depressed and non-depressed participants on baseline neural and parenting indicators? - Do baseline neural and parenting indicators predict response to FFT-CD? - Does change in parenting and neural functioning mediate change in depression from baseline to follow-up? Participants will: - complete baseline clinical measures - complete neuroimaging tasks via Functional Magnetic Resonance Imaging (fMR) - undergo a 12-session course of FFT-CD - complete follow up evaluations and neuroimaging
The goal of this observational study is to determine if nerve transfer surgeries improve upper extremity function and quality of life in patients with a high level cervical spinal cord injury. Participants will: - undergo standard of care pre- and post-op testing and study exams - complete pre- and post-questionnaires - undergo standard of care nerve transfer surgeries - follow-up with surgeon at 6/12/18/24/36 and potentially at 48 months - attend therapy at local therapist for up to 2 years postop.
This study aims to investigate the influences behind patient choices regarding involvement, discontinuation, or re-engagement in keratoconus clinical trials. Uncovering these factors is essential to enhance the relevance and efficacy of future research endeavors. In essence, this trial aims to deepen understanding of the factors influencing participation in keratoconus clinical trials. Elevating participation rates could expedite the development of innovative treatments for this challenging condition.
Among individuals with opioid use disorder (OUD), posttraumatic stress disorder (PTSD) presents a significant clinical challenge. The prevalence of PTSD is substantially higher in individuals with OUD than in the general population, with nearly 90% reporting lifetime trauma exposure and 33% meeting diagnostic criteria for PTSD. The primary objective of this study is to evaluate the efficacy of a novel telemedicine-delivered prolonged exposure therapy protocol for improving PE attendance and reducing PTSD symptom severity in individuals with concurrent PTSD and OUD.
Clinical trials, specifically focused on TBI, are crucial in assessing the safety and efficacy of new treatments. These trials serve as fundamental instruments in determining whether emerging medications outperform standard therapies, providing compelling evidence to support wider implementation. The main goal is to thoroughly scrutinize trial completion rates and voluntary withdrawals among this particular group of patients.
Participants with IBS are skin patch tested (no needles) to 80 different foods and food additives, compounded for patch testing, in search of food allergies. The testing requires 3 office visits within a 4 or 5 day period. The patches are taped to the back at Visit #. At Visit #2 48 hours later, the patches are removed from the skin and the outside border of each patch is marked with a felt tip marker. At Visit #3 (final visit) 1 or 2 days later, the patch test reading is performed by the doctor-investigator. An allergy is identified as a small red mark where the food was in contact with the skin for 48 hours. Those participants found to have food allergies are then placed on an avoidance diet (no calorie restriction) for 16 weeks where they either avoid eating the food(s) to which they are allergic (the "true" avoidance diet) or food(s) to which the testing did not show an allergy (this is called the "sham" avoidance diet). There is a 50/50 chance of going on either avoidance diet. The avoidance diet is assigned in such a way that neither the participant or the doctor-investigator knows which diet is being followed. After the 16 weeks, the participants answers a brief online questionnaire that asks about the IBS symptoms while following the avoidance diet. After the 16 week avoidance diet and final questionnaire are completed, those participants who were on the sham diet will be told of their true food allergies which they may try avoiding on their own.
The De-emphasize Parathyroid Hormone (DePTH) Study is a 12-month pragmatic, randomized, parallel-group, active comparator, open-label, blinded end-point study of 90 patients with incident or prevalent secondary hyperparathyroidism and kidney failure treated with in-center hemodialysis. It tests the hypothesis that low fixed-dose oral calcitriol (intervention) will have more favorable effects on a comprehensive panel of biomarkers that assesses mineral metabolism, bone turnover, and serum calcification propensity, compared with variably-dosed intravenous activated vitamin D titrated to PTH targets (usual care).
Medically complex older Veterans are at greater risk for progressive declines in physical function, lower quality of life, and increasing care needs. Additionally, older Veterans experience social isolation and loneliness, and have low levels of physical activity. While the Veterans Health Administration has established programs to address rehabilitation needs, these programs tend to be diagnosis-focused, lack self-management approaches, include low-intensity rehabilitation, and typically require in-person attendance. A MultiComponent TeleRehabilitation (MCTR) program that includes high-intensity rehabilitation and self-management interventions, social support, and telehealth and technology supports may be more effective in improving and sustaining physical function for older Veterans with complex health conditions. Therefore, this project is designed to determine whether the MCTR program improves strength and physical function more effectively than traditional interventions.
