This trial is being performed to evaluate the feasibility of the study protocol and to test the efficacy and safety of platelets stored at cold conditions (1-6°C) in 100% plasma for 10-14 days (CSP) in cardiac surgery patients who are actively bleeding and require platelet transfusion. Read Less

The purpose of this study is to understand variation in the symptoms of psoriasis and psoriatic arthritis using simple, scalable smartphone-based measurements. This study uses an iPhone app to record these symptoms through questionnaires and sensors. Read Less

The primary objective of this study is to evaluate the impact of LF111 and drospirenone (DRSP) 3.5 mg chewable tablets on bone mineral density (BMD) at the lumbar spine after 12 months (13 medication cycles) of investigation in comparison to non-hormonal contraceptive methods. Secondary objectives include further evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on BMD and bone turnover after 12 months (13 medication cycles) in comparison to non-hormonal contraceptive methods and assessing the general safety and tolerability of LF111 and DRSP 3.5 mg chewable tablets in comparison to non-hormonal contraceptive methods. Exploratory objectives include evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on body fat and lean mass after 12 months (13 medication cycles) of investigation. Read Less

The purpose of this study is to understand if training Parkinson's disease patients in classical guitar will improve motor function, mood, and quality of life. While medication has been found to be effective for many Parkinson's disease patients, many patients still have symptoms. Previous studies have found that music and rhythm-based activities can help Parkinson's disease symptoms. A previous study looked at the effect of playing classical guitar on Parkinson's disease symptoms. They found positive changes in Parkinson's disease symptoms that lasted for 6 weeks after the study ended. Further, there were positive changes in depression, anxiety, and quality of life. Read Less

While appendectomy has been the main treatment of appendicitis for over 100 years, recent European studies found that, at least among highly selected patients, antibiotics alone can be an effective alternative. Surgeons and patients alike have a difficult time deciding if surgery or antibiotics are the best choice to treat appendicitis. The goal of the TRIAD is to evaluate the patients who are a part of the TRIAD implementation program and assess satisfaction and decisional regret for patients with appendicitis. This information will be used to inform the design of decision-support interventions to help patients improve their ability to make an informed decision in-line with their preferences and values.

A pilot randomized controlled trial comparing intercostal nerve blocks, cryo-ablation plus intercostal nerve blocks, and serratus plane catheter plus intercostal nerve blocks in patients undergoing esophagectomies with minimally invasive thoracic approaches. Read Less

Building upon formative research, this mixed methods study will be conducted in three phases to develop, refine, and pilot-test a multi-component Family Peer Navigator model designed to increase access to and initial engagement in coordinated specialty care for early psychosis among Black/African American families.

Prospective, patient-blinded study utilizing a novel Continuous Reassessment Method that concomitantly considers both block success and block side effects (lung dysfunction) for brachial plexus nerve blocks. Read Less

The proposed three-year pilot randomized trial aims to test the effectiveness of the newly-redesigned paraeducator-delivered RUBI for use in Educational Settings (RUBIES) intervention compared to usual care training in reducing disruptive behavior in 80 elementary-school children with ASD. Given the critical need to understand not just whether, but also how interventions work, this study also will examine paraeducator- and child-level mechanistic pathways of the RUBIES intervention.

This project will develop, implement, and evaluate models for use of point-of-care nucleic acid testing (POC NAT) among HIV-negative persons seeking HIV testing, PEP, and PrEP and HIV-positive persons in community and clinical settings. Study aims #1 and #2 will evaluate the sensitivity and specificity of a qualitative POC NAT in persons not known to be HIV-positive and will determine the impact of its use on PrEP uptake and persistence among persons testing HIV-negative and on time to HIV continuum of care outcomes among persons testing HIV-positive. Aim #3 will implement a POC NAT-tailored behavioral intervention to evaluate impact on time to virologic suppression among PLWH receiving ART. Aim #4 will quantify the acceptability and feasibility of implementation of POC NAT in community and clinical settings and collect cost and related data for cost-effectiveness analyses. Finally, in Aim #5, a distinct but related study will compare the sensitivity, specificity, and agreement of multiple POC NATs over a range of HIV RNA levels. Read Less

Offloading Ankle Foot Orthoses (AFOs) are devices designed for people following lower-limb reconstruction to restore mobility by reducing mechanical loading through the injury site and redistributing it proximally. While they perform well for some users, their current form limits full functional potential and may put joints proximal to the injury at risk of long-term damage. This study is directed toward designing and testing a lightweight, variable stiffness, dynamic brace that can adjust in response to user activity. Read Less

Rationale: The highest rates of coronavirus disease (i.e., COVID-19) vaccine hesitancy in the US are among young adults (YAs) aged 18-25. Our preliminary studies show that social norms - perceptions of peers' vaccination attitudes/behaviors - are most strongly related to YAs' vaccine intentions/uptake. Most YAs underestimate the perceived importance of vaccination and their peers' intentions to be vaccinated. The proposed research will develop and test an intervention to correct misperceived norms for vaccination hesitancy and uptake. Methodology: Rapid prototyping with 20 unvaccinated YAs will help refine the content and design of the online intervention. Then, a diverse national sample (N=600) of unvaccinated YAs will be randomized to treatment or an attention-matched control. The treatment condition will receive personalized normative feedback (PNF) designed to correct normative misperceptions for vaccine hesitancy and uptake. Normative feedback will be derived from the US Census Bureau's Household Pulse Survey. Follow-up surveys will be administered at 1, 2, 3, and 6 months to assess key outcomes including vaccine uptake, intentions, and reasons for vaccine hesitancy. Aims and Data Analysis: Aim 1: Develop and refine a PNF intervention for vaccine hesitancy/uptake with user feedback from YAs. Rapid analysis of qualitative data will involve looking for themes in responses. Changes will be made iteratively to refine intervention content, design, and delivery. Aim 2: Evaluate intervention efficacy for increasing vaccine uptake and reducing time to first vaccine dose, relative to control, over the following year. Aim 3: Examine mediators (changes in perceived norms) and moderators (intellectual humility, identification with other people and young adults) of intervention efficacy. A longitudinal moderated mediation model will be examined. Impact: Findings will clarify the causal role of psychological determinants of vaccine hesitancy (social norms, intellectual humility, group identification). If preliminary intervention efficacy is supported, this intervention could be a low-cost, and easily disseminated strategy to promote YAs' vaccine uptake and contribute to public health efforts to address the COVID-19 pandemic.
