This research will assess the ability of nightly objective sleep scheduling and sleep heart rate data to predict variation in suicidal ideation in U.S. military veterans identified as high-risk according to actuarial and/or clinical indicators. These data will be recorded using one of two low-cost, commercial, zero-burden, mattress actigraphic systems that enable remote, centralized, data access. Participants will be veterans accrued both from the REACH VET and local high-risk lists, a process involving collaboration with the Suicide Prevention Coordinator at the VA Palo Alto HCS. In order to minimize burden, participants will be screened by telephone, consented by mail and telephone, administered a brief admission psychometric interview by telephone, and mailed a sleep sensor system and instructions for its installation in their home. Once sleep data collection has commenced, a trained interviewer will contact the participant by telephone weekly and administer the Columbia-Suicide Severity Rating Scale. Data collection will continue for three months. The study targets a sample of 40 veterans. Longitudinal mixed effects modeling will be employed to determine whether changes in sleep scheduling and sleep heart rate predict changes in suicidal ideation. Read Less

Few trials have reported the safety and efficacy of the COVID-19 vaccines. However, these trials were mostly focused on post-vaccination adverse events and short-term antibody detection with none monitoring the presence of immunoglobulin G (IgG) in blood at long-term follow-up after the vaccination. This study aims to evaluate the immune response in post-vaccinated individuals across a follow-up period of one year. Read Less

The 3q29 deletion syndrome is caused by a deletion of a small part of human chromosome 3, and the duplication syndrome is caused by a duplication of this same small region. The purpose of this study is to understand the medical and behavioral consequences of these syndromes. Read Less

With an average of 21,000 diagnosed brain injuries each year among military personnel, traumatic brain injury (TBI) remains a major health concern for the United States Military Health System. Mild traumatic brain injury (mTBI) is the most common type of brain injury sustained by military personnel and may result in chronic cognitive impairment.Unfortunately, many service members (SMs) have a history of multiple head injuries as well as psychological co-morbidities that negatively influence recovery. Advances in treatment options for cognitive rehabilitation following mTBI have been of increasing interest to the medical community and may increase treatment efficacy for injured SMs to ensure force readiness. Cognitive Rehabilitation (CR) for severe brain injury focuses on compensatory strategies for activities of daily living such as using lists to remember grocery items or reminders to take medications and attend medical appointments. Research has shown CR interventions to have considerable effectiveness in the acute and sub-acute phase of recovery after severe TBI. But there is insufficient evidence that they improve rates of individuals returning to work, independence in activities of daily living (ADL), community re-integration, or quality of life. Read Less

A novel patent-pending "Prodovite®" VMP35 Multi-Nutrient-Complex (MNC), a vitamin, mineral, and phytonutrient encapsulated liquid formulation, was prepared using a novel proprietary SK713 SLP multi-lamellar non-GMO phospholipid nutrient absorption/delivery technology in a state-of-the-art multistep cGMP and NSF-certified manufacturing facility. This developmental technology is biodegradable and biocompatible. Preliminary study in our laboratory demonstrated the efficacy of "Prodovite®" VMP35 in Sports Nutrition. The investigators hypothesize that "Prodovite®" VMP35 supplement will enhance strength, endurance, and athletic performance; and improve energy output, lean-body muscle mass, increase exercise tolerance, recovery, and improve anabolic parameters in healthy human subjects. The aim of this randomized double-blind placebo-controlled study is to evaluate the effect of oral supplementation of "Prodovite®" VMP35 on the parameters. The investigators hypothesize that "Prodovite®" VMP35 supplementation will enhance all the athletic parameters and improve blood chemistry parameters in healthy human subjects. Accordingly, 150 healthy male and female subjects will be randomly assigned to receive either "Prodovite®" VMP35 or placebo in the form of single dose sealed containers for 90 consecutive days and muscle strength, endurance, speed, anabolic/catabolic parameters and muscle mass will be evaluated by dual energy X-ray absorptiometry (DEXA), hand-grip strength test, cycle ergometer test, spirometer assessment and assay of Blood chemistry and serum biomarkers will be evaluated before and after intervention.

The purpose of the ESCAPE Study is to determine the extent to which epidural spinal cord stimulation (SCS) reduces arterial blood pressure (BP) in patients which chronic low back pain and hypertension. We also aim to determine the extent to which higher baseline BP (i.e., hypertension) predicts reductions in pain following SCS implant. This is an observational study of patients undergoing an implantation of a SCS device. Read Less

Exercise tolerance decreases with age and a sedentary lifestyle. Muscle critical power (CP), is a sensitive measure of exercise tolerance that is more even more relevant to and predictive of endurance performance than VO2max. While recent evidence indicates that CP and muscle function decrease with aging, the cause of this decrease in CP and the best way to mitigate the decrease in CP are unknown. This study will: Measure knee extensor CP in young and old individuals and determine the extent to which changes in muscle oxygen delivery (e.g. resistance artery function, maximum exercise blood flow), muscle mass and composition (e.g. whole-muscle size, muscle fiber cross-sectional area) and mitochondrial oxygen consumption (e.g. maximal coupled respiration of permeabilized fibers biopsied from the knee extensors) contribute to the decrease in CP with age. Examine the effectiveness of two different therapies (1. High Intensity Interval Training, HIIT and 2. Muscle Heat Therapy) at improving muscle function and critical power in young and older adults. Examine the impact of muscle disuse (2 weeks of leg immobilization), a potential contributor to the decrease in muscle function with aging, on muscle function and critical power and determine if heat therapy is an effective means of minimizing the impact of disuse on muscle function and critical power.

MB-College (MBC) is an 9-week, 9 session program (i.e., the study intervention being tested in the RCT) providing systematic and intensive training in mindfulness meditation practices, applied to health behaviors relevant to college students and young adults. The MBC intervention will be administered live, online via the free video conferencing platform, Zoom, to all eligible study participants enrolled in the active arms of the study. In addition to the 9-week, 9 session MBC class, referred to as "standard dose MBC" from here on out, investigators will also be testing a "low-dose MBC" version of the intervention, where each weekly session will run 1.5 hours in length rather than 2.5 hours. This is a 3-arm randomized controlled trial. The standard-dose and low-dose versions of the MBC intervention will be compared to a third arm of the study, a health education active control group. Members of the control group will be offered the MBC class upon completion of the research study. The Study Aims are to: (1) Evaluate feasibility and acceptability of MBC delivered in two online formats (standard dose vs. low dose). (2) Evaluate impacts of MBC standard-dose vs. MBC low-dose vs. health education control group on health conditions relevant for emerging adults, demonstrated to be influenced by MBC in a prior study, specifically depressive symptoms, loneliness, and sedentary activity. (3) Explore mechanisms by which MBC may exert effects on aforementioned health conditions, including interoceptive awareness, decentering, and perceived stress. Participant Population: young adults aged 18-29 years of age, residing in the United States who screen eligible will be invited to enroll. Students will be screened using a two-part process taking place online. Research assessments at baseline and 3-month will take place digitally using Qualtrics, LLC (Provo, UT, USA) survey management tool. Participants will be sent secure links via email that can be accessed with their participant identification number. Enrolled participants will be randomly assigned to one of three groups: (1) standard MBC; (2) low-dose MBC or (3) health education control group. The control group will be given the opportunity to participate in the intervention after the study MBC course is completed and follow-up assessments have been administered. Read Less

Most pediatric gastroenterologists use an endoscopic pull technique to place gastrostomy tubes. We assessed an endoscopic gastropexy technique for gastrostomy tube placement that allows immediate placement of a low profile gastrostomy tube or gastro-jejunostomy tube. The procedure involves endoscopy with the placement of three T-fasteners that are placed through the skin into the stomach, placating and securing the stomach to the abdominal wall. This attachment process promotes formation of a stable gastrostomy tract, facilitating an immediate placement of a low profile gastrostomy button or gastro-jejunostomy tube. Serial dilators are then used to obtain the desired diameter of the ostomy for the tube placement. The gastropexy technique is most often associated with laparoscopic procedures involving gastric volvulus or complicated GERD, but little has been published investigating the outcomes of pediatric gastrostomy tube placement with the use of the gastropexy technique.
