The investigators are collecting genetic information through blood samples as well as clinical and EEG data from over 1000 people with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe and North America. This study will draw on both existing and new samples from JME patients. These will be compared to anonymised data from samples for 2000 controls. The goal of this study is to find the genetic cause of JME. Finding the cause will help create better treatments for JME, as well as improve patient outcomes by allowing us to detect it earlier.

This study will examine the efficacy of an internet-based brief intervention designed to reduce risky behavior in Soldiers as they transition from Active Duty into the civilian workforce as a Veteran. Up to 700 soldiers intending to separate from the Army will be recruited, with the intention of drawing a final sample of 450 participants. Study participants will be randomly assigned to either the intervention or the control group, stratified by age and gender. Read Less

Work capacity is an important predictor of declining health or physical function, and of mortality, and is commonly measured as peak oxygen consumption. Peak oxygen consumption is very low in individuals with Down syndrome, the most prevalent genetic cause of intellectual disability. Previous research suggests individuals with Down syndrome may experience a double disadvantage when they are exercising: they may not be able to increase cardiac output sufficiently and they may not be able to allocate adequate blood flow to the working muscles. The aim of this research proposal is therefore to investigate the responses in central and peripheral blood flow regulation and cardiac autonomic function to exercise training in individuals with DS. Additionally the effects of exercise on gait, balance and attitude towards exercise in individuals with DS are investigated. Read Less

Botox injections into the thyroarytenoid muscle are a predictable and effective treatment for SD, but typically result in transient symptoms of voice weakness and breathiness during the first 2-3 weeks after injection. Investigators hypothesize that voice weakness and breathiness after Botox treatment can be alleviated using amifampridine. Read Less

There are more than 2.1 million people in the United States with opioid use disorder, and according to preliminary data from the US Centers for Disease Control and Prevention opioid overdose deaths rose 36% to more than 69,000 deaths in 2020. Treatment with buprenorphine or methadone reduces overdose deaths in patients with opioid use disorder. However, most patients with opioid use disorder do not receive treatment. In addition to the rising rates of morbidity and mortality, the healthcare, social, and societal costs of the opioid epidemic are roughly one trillion dollars annually. Rapidly scalable strategies are needed to increase access to treatment and improve treatment retention. The investigators propose a novel buprenorphine micro-dosing study to evaluate the pharmacokinetics, treatment retention, and qualitative outcomes in participants transitioning from methadone maintenance therapy to buprenorphine using a micro-dosing initiation in the outpatient setting. The proposed study will report participant pharmacokinetics, treatment retention, Clinical Opiate Withdrawal Scale (COWS) score, Treatment Satisfaction Questionnaire for Medication (TSQM) score, and other qualitative outcomes.

NTS-104 TRIS will be administered as a single intravenous dose to healthy subjects at doses of 0.8, 4, 8 and 16 mg/kg in 4 Cohorts. Each cohort of 8 subjects will begin with dosing 2 sentinel subjects with one being given the investigational product and one the placebo. If no safety issues arise, dosing the remaining subjects in the cohort will begin. A Safety Review Committee will review the safety and pharmacokinetic data before approving escalation to the next dose level. Read Less

The over-arching goal of the Contrast-Enhanced Spectral Mammography Imaging Screening Trial (CMIST) is to determine if dual-energy contrast-enhanced spectral mammography (CESM) can detect more cancers with fewer false positives than digital breast tomosynthesis (DBT) in women with dense breasts. Aim 1: To evaluate the performance of CESM compared to DBT at baseline for breast-cancer screening in women with dense breasts. Aim 2: To evaluate the performance of CESM compared to DBT at the 1-year follow up for breast-cancer screening in women with dense breasts. Read Less

Phase I study with the hypothesis that Pulsed Low Dose Radiation (PLDR) radiation delivery technique can significantly decrease the rate of severe acute esophagitis in patients receiving concurrent Chemo-radiation therapy (CRT) for non-small cell lung cancer or esophageal cancer while maintaining similar efficacy. For these patients, the rate of severe acute esophagitis during concurrent CRT is high (approximately 20%) when conventional external beam radiation is utilized. Severe acute esophagitis can cause many adverse consequences such as severe discomfort, weight loss, hospitalization, interruption/early termination of treatment, and worse surgical complications for those who receive surgery after CRT. PLDR radiation has the potential to maintain the tumor control rates of conventional radiation while decreasing the toxicity to the surrounding normal tissue 29-35. We have completed accrual to a phase I PLDR radiation study, in which patient received palliative re-irradiation with PLDR technique for their metastatic disease in previous irradiated field. In that phase I study, PLDR demonstrated safety for acute toxicities in the setting of re-irradiation for a total dose of 50 Gy, with analysis of 60 Gy pending. The follow up time for that phase I study is limited as most enrolled patients have short overall survival due to their terminal illness. This proposed phase I study is, to our knowledge, the first clinical study with combination of PLDR radiation and concurrent chemotherapy for definitive treatment. Read Less

The study objectives are to define the safety and tolerability profile of oral, single ascending dose (SAD) levels of HOPO 14-1 capsules in cohorts of healthy participants and to assess the pharmacokinetic (PK) and excretion profile of HOPO 14-1. The study hypothesis is that a single dose of HOPO 14-1 will be safe and tolerable up to 7500 mg. Read Less

Focus of attention refers to what a person is thinking about during a task, with an internal focus being thinking about what one's body is doing and an external focus being thinking about a target or outcome in the environment. The purpose of this study is to fill some of the gaps in the literature by examining the effects of focus of attention on performance and learning of sit to stand in individuals post stroke. This study will investigate whether an internal or external focus of attention can lead to improved use of the affected lower extremity during the sit to stand transition, while maintaining an upright trunk position.

This project seeks to identify the how walking impairments in stroke survivors contribute to mobility deficits through the use of behavioral observations and computational models. The chosen approach integrates biomechanical analyses, physiological assessments and machine learning algorithms to explain how asymmetries during walking influence balance and the effort required to walk. Ultimately, the results of this work may lead to more personalized rehabilitation strategies to improve walking capacity and efficiency, and ultimately reduce fall risk in stroke survivors.
