The electrolyte test products are composed of powder and provided in individual stick packs with 5 vitamins including Vitamins B3, B5, B6, B12 and Vitamin C. The products are gluten-, soy-, and dairy-free, and provide electrolytes at concentrations well below the daily value (DV). The DV tells us how much a particular nutrient in a serving of a food product contributes to a daily diet, based on a standard 2000 calorie diet. Despite what the name suggests, this product is taken orally, not intravenously. These packets contain a small percentage of the needed total daily electrolytes but adequate amounts to replace lost electrolytes as a result of physical activity. The products will be consumed following a 90-minute bout of cycling exercise at a moderate intensity of 70-80% max heart rate, at 30-32°C (86-89°F) and 50 ± 5% relative humidity. This same exercise duration and room temperature has been used in a recent study, which also utilized the same body temperature monitoring device as proposed in the present study. The purpose of the exercise bout is to simulate what many individuals are exposed to when exercising in the heat and to moderately dehydrate subjects, as would be the case during a moderate run or cycling event in exercise-trained individuals. Subjects will report to the lab on three separate occasions to consume one of the 3 drinks (hydration multiplier, sugar-free hydration matrix, or water), in random order. The drinks will be consumed during the post-exercise period (30 minutes following the completion of exercise). Read Less

The purpose of this research is to collect biological samples (urine) to develop assays for immune biomarkers to possibly in the future be able to screen subjects with Fabry disease and be able to understand better progression of nephropathy in Fabry disease and predict nephropathy in Fabry disease.

More than two million Americans are currently living with a full or partial limb loss, and an additional 185,000 amputations occur each year. The majority of amputations occur in the lower limbs. There are many potential causes for amputation, but the majority can be attributed to vascular diseases, such as diabetes, traumatic injury, and cancer. For these individuals, prosthetic devices play an important role in restoring mobility and enabling them to participate in everyday activities. However, when learning to use these devices, patients often alter their movement patterns to compensate for pain or discomfort, a decreased ability to feel what their prosthetic limb is doing, and/or a fear of falling. By changing their movement patterns, patients will tend to am their intact leg, which has been shown to lead to long-term joint damage and chronic injury. For perspective, 75% of United States veterans living with amputation are diagnosed with a subsequent disease affecting their muscle, bone, and/or joint health. Therefore, therapy sessions, known as gait retraining, are an integral part of teaching prosthesis users to walk in a safe and efficient manner. With recent advances in wearable technology, researchers and therapists have begun exploring the use of biofeedback systems to assist with this retraining. In these systems, wearable sensors are used to measure how the patient is moving in real-time, and can provide information on how much time they spend on each leg and how much each joint moves during walking. Biofeedback refers to the process of communicating the information from these sensors back to the patients instruct them whether they need to change their movements. Previous research has shown that these systems have excellent potential for helping patients with physical disabilities improve their quality of motion. However, relatively little research has explored how well individuals with above-knee leg amputations respond to biofeedback during gait retraining. Importantly, the question of whether the new movement patterns taught using biofeedback will persist after training has finished remains unanswered. Therefore, the primary objective of this research is to determine whether biofeedback is a feasible tool for gait retraining with above-knee prosthesis (including a prosthetic knee, ankle, and foot) users. To answer these questions, forty individuals currently using above-knee prosthetic systems will undergo a single session of biofeedback training. Half of these populations will be from the civilian population, and half will be military veterans. During this training, the biofeedback system will apply short vibrations - similar to those generated by cellphones - to their skin every time that the patient reaches the desired degree of hip rotation during walking. Participants will be instructed to keep increasing their hip motion until they feel a vibration on every step. Before training, they will be instrumented with a wearable motion captures system, pressure sensors embedded in their shoes, and a wearable heart rate monitor. Using these devices, researchers will measure the participants' walking patterns without biofeedback determine their current ability. Once training is complete, their walking patterns will be measured again, first while using the biofeedback system, and then again fifteen minutes and thirty minutes after the biofeedback system has been removed. The data measured during these tests will enable researchers to calculate functional mobility scores that are used to evaluate the quality of a patient's walking, and then compare how these scores change before, during, and after biofeedback training. The knowledge gained through this research constitutes a critical step towards identifying optimal biofeedback strategies for maximizing patient mobility outcomes. The findings will be essential for the development of gait retraining protocols designed to reduce the incidence of chronic injury, and enable patients to achieve their full mobility potential. Building on these results, the next research phase will be to incorporate biofeedback training into a standard six-week gait retraining protocol to evaluate its long-term effectiveness as a rehabilitation tool. Unlike traditional gait retraining, which requires patients to visit clinics in-person for all sessions, the wearable, automated nature of biofeedback training will allow patients to continue gait training from home. This ability will enable patients to continue training activities between sessions, and ultimately may be able to substitute for some in-person visits. This potential for remote therapy has exciting implications for improved access to care for individuals living long distances from their rehabilitation providers, or those suffering from social anxiety, as well as during global health pandemics where in-person visits are difficult.

To determine if a pre-operative ketamine infusion would provide a similar decrease in post-operative analgesic and opioid consumption as intra-operative ketamine, but expand the monitoring period through the post-operative phase up to 90 days. Hypothesis is that pre-operative ketamine infusion will lead to a decrease in narcotic consumption from baseline following an elective cervical or lumbar fusion, leading to increased functionality and quality of life for these patients.

The researchers want to find out more about a standalone software application, ImPACT Online and how it relates to other commonly used tests of memory, attention and reaction time. ImPACT Online is a computer-based neurocognitive test for concussion management. The test was designed to help measure the effects of concussion on cognitive processes (for example, memory, attention, brain speed) and visual functioning. Read Less

This is a pilot study using \[18F\]F AraG PET imaging to evaluate the immunological response to checkpoint inhibitor therapy (CkIT) in patients with advanced NSCLC tumors at multiple study sites. The main objectives of the study are to quantify the change in \[18F\]F AraG PET signal before and after CkIT therapy, and to correlate this change in \[18F\]F AraG PET signal with a radiographic response.

A Phase 2a, randomized, double-blind, placebo-controlled, multiple ascending dose study in patients who are hospitalized with presumed pneumonia requiring supplemental oxygen therapy. The purpose of this study is to examine the safety, tolerability and efficacy of AV-001 Injection administration daily to the earlier of day 28 or EOT (day prior to hospital discharge). A total of 120 eligible patients (20 patients in each of cohort 1, 2 and 3 and 60 patients in cohort 4) will be recruited from up to 25 participating institutions/hospitals. Patients will be randomized in a 1:1 ratio to receive either AV-001 Injection or AV-001 placebo Injection, together with standard of care (SOC). Read Less
