This is an open-label, two period, fixed-sequence, drug-drug interaction study to compare the PK and PD of orally administered AV-101 alone and in combination with probenecid in healthy subjects. In Treatment Period 1, subjects will receive AV-101 following an overnight fast of at least 8 hours. In Treatment Period 2, subjects will fast overnight for at least 8 hours, and then receive AV-101 2 hours after receiving 1,000 mg probenecid. Each Treatment Period will be separated by a washout period. The doses of AV-101 in Cohort 1 and a possible Cohort 2 will be 360 mg and 720 mg, respectively. Optional Cohorts 3 and 4 may be enrolled depending on results from Cohorts 1 and 2. CSF will be collected via indwelling catheter to determine the PK of AV-101 and its active metabolite 7-Cl-KYNA.

If your serious vaccine-induced adverse event has been entered in the CDC Vaccine Adverse Event Reporting System (VAERS) we are interested in enrolling you for this study in order to log your symptoms. The primary goal of this study is to create a national database and gather vaccine-associated serious adverse events/injury data from newly vaccinated individuals in the US in order to identify the possible underlying causal relationships and plausible underlying biological mechanisms. The project aims to identify the genetic determinants of vaccine-induced adverse response by studying host genetics. We plan to use whole genome sequencing to identify single nucleotide polymorphisms associated with cardiovascular, neurological, gastrointestinal, musculoskeletal and immunological symptoms induced by vaccine administration. The secondary goal is to establish criteria that enable classification of vaccine-induced adverse events/injuries compare data from our database with the official Vaccine Injury Table National Vaccine Injury Compensation Program on or after March 21, 2017. The tertiary goal is to establish a database to gather detailed long-term adverse reaction data from subjects enrolled in FDA Emergency Use Authorized vaccine clinical trials. Read Less

Subjects will participate in a 2-visit study protocol in which they will be administered cannabis of pre-determined concentrations and asked to complete a simulated drive in a driving simulator. Subjects will be scanned on two SpotLight-THC (Alpha and Beta iterations) devices and peripheral venous whole blood will be collected from subjects for analysis on up to four occasions on each visit. The purpose of the investigation will be to determine whether the SpotLight-THC device is a reliable measure of THC impairment at the roadside, with an objective to identify a unique blood analyte architecture for THC impairment using near infrared light and machine learning.

Individuals with low socioeconomic status (SES) are more likely to have a stroke, more disabled at 3 months, and less likely to be independently ambulatory. Individuals with low SES struggle to adhere to physician guidelines because of 1) increased disability leaves patients ineligible or unable to tolerate therapy, and 2) poor access to quality care i.e., lack of transportation to therapy. To reduce post-stroke disparity in low SES groups, we need to invest in development of novel tools that make therapy more accessible. For the past 5 years, the PI has been developing Startle Adjuvant Rehabilitation Therapy (START), a tele-enabled, low-cost treatment to improve upper-extremity therapy outcomes in individuals with stroke - in particular individuals with severe-to-moderate stroke. START is the application of a startling, acoustic stimulus (via headphones) which increases the intensity of practice, particularly in severe patient populations. START is adjuvant, meaning it does not replace clinical practice but instead enhances current evidence-based treatments. Objective: we seek to determine if START can be used to enhance functionally relevant movement of the upper extremity. Preliminary data: Individuals with severe-to-moderate disability from a stroke completed a remotely delivered, 3-day training of object manipulation with START. Box and Blocks, which was targeted during training, demonstrated a large increase under START (+47.1%) compared to Control (+3.3%). Modified functional reach was also increased under START (+8.9%) compared to Control (+1.1%). Impairment also decreased under START (Upper-Extremity-Fugl-Meyer: +8.6%) resulting in subject-reported increase in arm function both in quantity (Motor Activity Log: +26.2%) and quality (+20.2%). These results indicate that START can be deployed remotely and may prove a valuable, adjuvant tool to enhance functional upper extremity movement. We propose to perform a Phase 1 clinical trial on a larger cohort of 58 subjects, with a longer, 5-day training with the goal of establishing that START can 1) enhance functional movement of the upper extremity and 2) generate sustainable changes that impact quality of life. Impact: This proposal is significant because it tests a tool that has the potential to directly target the causes leading to disparity of care for individuals with low SES. A third (34%) of 6.5 million people in the U.S. with stroke are on Medicaid or uninsured. Our best evidence-based therapies (e.g., high-intensity, CIMT) and our emerging rehabilitation technologies (e.g., TMS, robotics) are inaccessible to our minority and low SES populations. START addresses disparity because it 1) targets individuals with severe disability, which disproportionally affects low SES and minority groups, and 2) is tele-enabled eliminating transportation which 60% of individuals with low SES report as a barrier to care. If successful, this study will set the stage for larger trials to establish 1) the effectiveness of START to be incorporated into traditional therapy and as well as patient compliance, adherence, and tolerance - particularly in low SES groups.

Arthritis is a common condition in the United States, and a leading cause of pain and disability. Physical exercise is recommended for managing arthritis, but access to evidence-based exercise programs is limited, particularly in rural areas. Therefore, the investigators propose to evaluate remote delivery of an evidence-based exercise program called Enhance Fitness (EF) that is recommended for arthritis management. The primary purpose of this study is to determine if remotely delivered EF is non-inferior to in-person EF on primary and secondary outcomes. Read Less

The development of symptomatic heart failure is frequently preceded by a pre-clinical period of structural remodeling in the heart. The remodeling process driving this transition, however, remains poorly understood. The investigators hypothesize that imaging the diffusion of water in the heart with MRI will allow its microstructure to be resolved. The investigators further hypothesize that the characterization of microstructural changes in the heart will help elucidate the pathogenesis of heart failure and the transition from a compensated to a decompensated state. Patients with recent myocardial infarcts and left ventricular hypertrophy, who are at risk for the development of heart failure, will be enrolled. The participants will undergo serial diffusion tensor MRI (DTI) imaging of the heart to characterize changes in myocardial microstructure over time. Read Less
