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 research trial studies the incidence of human immunodeficiency virus (HIV) infection in screening Indian men who have sex with men (MSM). Gathering health information over time from Indian MSM may help doctors determine how many Indian MSM develop new cases of HIV infection.
The purpose of this research study is to examine the effects of physical therapy on the spinal discs. Back pain is the number one cause of disability in the US, and the spine is the most common location of chronic pain in Veterans. Physical therapy is often very effective at improving patients' back pain, but it does not work for everyone, and it is not understood how physical therapy alters the tissues within the spine. With this research the investigators hope to learn if the investigative team can measure changes to the spinal discs on MRI scans that might predict if a patient's back pain will improve with physical therapy or not.

To evaluate the efficacy of rituximab combined with omalizumab in achieving sustained complete remission, evaluated by Bullous Pemphigoid Disease Area Index (BPDAI) in patients with bullous pemphigoid (BP) at Week 24 in patients with active moderate-to-severe BP refractory to rituximab therapy alone.
Working through regional Accountable Care Organizations (ACO) the sponsor will establish a 2-year pilot project to demonstrate that early recognition and intervention in the various Social Determinant of Health (SDoH) domains can reduce avoidable Emergency Department (ED) visits by high utilizers. The regional ACO's will contract with Medicaid Managed Care Plans to assign traditional high ED utilizing members to the pilot project. Members will be offered enhanced peer facilitated care management services connecting members with available SDoH community based services. Members fitting our eligibility criteria will self-select by way of completing a pilot project consent form.
Long bone defect (LBD) is defined as a focalized loss of bone tissue in any long bone of the upper or lower extremity. Long bone defects are a complex problem, that may arise as a complication of many different pathologies, such as trauma, tumors or infection. Whereas post-traumatic defects are the largest group. Reports estimate that there are almost 4 million bone grafting procedures worldwide per year. However, limb reconstruction in the context of a bony defect is challenging and up to date there is little evidence and treatment recommendations. In a multi-national approach, the aim of this project is to set up an international, multicenter registry to gather information and details on prevalence or incidence, current treatments, complications and outcome.
As most adolescents visit a healthcare provider once a year, health behavior change interventions linked to clinic-based health information technologies hold significant promise for improving healthcare quality and subsequent behavioral health outcomes for adolescents (Baird, 2014, Harris, 2017). Recognizing the potential to leverage recent advances in machine learning and interactive narrative environments, the investigators are now well positioned to design health behavior change systems that extend the reach of clinicians to realize significant impacts on behavior change for adolescent preventive health. The proposed project centers on the design, development, and evaluation of a clinically-integrated health behavior change system for adolescents. CHANGEGRADIENTS will introduce an innovative reinforcement learning-based feedback loop in which adolescent patients interact with personalized behavior change interactive narratives that are dynamically personalized and realized in a rich narrative-centered virtual environment. CHANGEGRADIENTS will iteratively improve its behavior change models using policy gradient methods for Reinforcement Learning (RL) designed to optimize adolescents' achieved behavior change outcomes. This in turn will enable CHANGEGRADIENTS to generate more effective behavior change narratives, which will then lead to further improved behavior change outcomes. With a focus on risky behaviors and an emphasis on alcohol use, adolescents will interact with CHANGEGRADIENTS to develop an experiential understanding of the dynamics and consequences of their alcohol use decisions. The proposed project holds significant transformative potential for (1) producing theoretical and practical advances in how to realize significant impacts on adolescent health behavior change through novel interactive narrative technologies integrated with policy-based reinforcement learning, (2) devising sample-efficient policy gradient methods for RL that produce personalized behavior change experiences by integrating theoretically based models of health behavior change with data-driven models of interactive narrative generation, and (3) promoting new models for integrating personalized health behavior change technologies into clinical care that extend the effective reach of clinicians.
For many Veterans, success in achieving goals at work, school and in other aspects of life are top priorities. The abilities to regulate attention, remember key information, and stay calm and on track are fundamental to this success. Unfortunately, Veterans who have experienced a traumatic brain injury (TBI) often struggle with these very abilities, and a number of barriers can make it difficult for them to access the help Veterans need. Tele-rehabilitation has the potential to overcome some of these barriers and increase access to care, enabling providers to better reach Veterans 'where they are' in their communities. This project will assess two different approaches to brain injury rehabilitation that seek to help Veterans build personal strengths to better accomplish their goals. Both approaches will be delivered remotely via tele-rehabilitation and augmented by digital apps to best support Veterans' learning in community settings outside the VA.
The purpose of this study is to use a device called I-Portal® Portable Assessment System (I-PAS) to record eye movements in response to a number of visual and auditory stimuli designed to evaluate neural brain pathways related to oculomotor, vestibular, reaction time and cognitive (OVRT-C) development. The goal of this research is to collect normative data for the OVRT-C tests from a healthy pediatric population.
The purpose of the current study is to determine the effects of applying epidural stimulation (ES) on motor control recovery in Veterans with SCI. The intervention will be accompanied with the use of a powered exoskeleton (EKSO®) for 6 months to facilitate standing and to produce step-like movement in persons with chronic motor complete (AIS A or B) SCI and level of injury below C5 . Walking speed, distance, muscle activation pattern as measured by surface EMG and walking parameters including stand-up time, walking time, distance will be considered primary outcome variables. Cardiovascular performance, as measured by resting blood pressure and heart rate, peak oxygen consumption during walking, energy expenditure, whole and regional body composition assessments will also be measured. The effects of training (ES+EKSO) on , and speed of walking will also be evaluated.
