Deep Brain Stimulation of the subthalamic nucleus (STN) has become a standard of care, FDA-approved treatment for Parkinson's disease, with stimulation delivered at a constant amplitude and voltage, operating in an open-loop fashion that does not respond to a patient's current state. Although gait deficits and freezing of gait may initially respond to continuous open-loop deep brain stimulation (olDBS) and medication, the symptoms often recur over time. The episodic and predictable nature of FOG makes it well suited for adaptive DBS (aDBS) and a device that overcomes the limitations of traditional high frequency olDBS and is capable of adapting therapy either in the frequency or intensity domain transiently to treat FOG while also treating other PD signs such as tremor and bradykinesia. The purpose of this study is to determine the feasibility of an adaptive DBS system, that responds to patient-specific neural and kinematic variables with customized DBS parameters. Read Less

Chronic Obstructive Pulmonary Disease (COPD) is prevalent and debilitating chronic disease in Veterans. COPD is highly co-morbid with depression and anxiety conferring greater morbidity and mortality risk. Physical activity is a modifiable behavior that can improve COPD outcomes. However, to date, interventions targeting physical activity have not addressed the high comorbidity between COPD and depression and/or anxiety symptoms ("emotional distress") despite emotional distress predicting poorer response to physical activity interventions. This CDA-2 proposal will develop and test the acceptability and feasibility of an integrative physical activity and mental health intervention for Veterans with COPD, emotional distress, and low physical activity. The intervention will be delivered via VA Video Connect enabling access to care among Veterans with substantial barriers to hospital-based outpatient care. Read Less

This clinical trial aims to learn about the alterations in insulin resistance and metabolic flexibility following a transition to an obesogenic lifestyle in fit young men and women. The main questions it aims to answer are: 1. Does adding excess carbohydrates when transitioning to a sedentary lifestyle promote insulin resistance and impaired 24hr glucose regulation in healthy men and women? 2. Does adding excess carbohydrates when transitioning to a sedentary lifestyle lower the body's ability to break down fats and carbohydrates in healthy men and women? 3. Does the added physical activity blunt shifts in carbohydrate and fat oxidation in healthy men and women? Read Less

Obesity and cardiometabolic risks are significant public health issues, with about two-thirds of U.S. adults overweight or obese. Weight loss can prevent these health problems, but current lifestyle interventions have limited success. New, effective strategies are needed to address this rising issue at the population level. The goal of this clinical trial is to investigate how a behavioral intervention combined with technology impacts weight loss in young adults. The main questions it aims to answer are: • How does the combination of behavioral intervention and technology influence weight loss in young adults? Read Less

This project is a single-site, two-arm, randomized controlled pilot study examining the impact of a 2-hour version of Mindfulness-Oriented Recovery Enhancement (ONE MORE) training for individuals with HIV and chronic pain. Read Less

This study is being done to obtain samples from patients with primary hyperoxaluria, cystinuria, adenine phosphoribosyl transferase (APRT) deficiency, and Dent disease, and from their family members, for use in future research. Read Less

Persistent pain is a public health epidemic. The current protocol seeks to develop technology to aid patients' tracking of patients' pain, medications and pain-related variables. The investigators seek to talk with patients in co-investigator's clinic to solicit feedback, as well as pilot test the technology with pain patients. Read Less

This is a Phase 1b/2, single-arm, open-label, dose-escalation study including 2 stages: Phase 1b: Dose-Escalation Stage (Single-Dose and Consecutive-Dose Periods) Phase 2: recommended Phase 2 dose (RP2D) of chiauranib will be given to all patients enrolled in this phase once daily for 28-day cycles continuously with no interruption between cycles.

The purpose of this study is to test whether or not regular exercise training may improve brain blood flow regulation in patients with chronic kidney disease (CKD). Read Less

A Phase 2 multi-center, open-label, single arm study of nab-sirolimus in patients with well-differentiated neuroendocrine tumors (NETs) of the gastrointestinal tract, lung, or pancreas who have not received prior treatment with mTOR inhibitors Read Less

There is a high prevalence of anxiety and depression in patients with Type 2 Diabetes (T2D). While past studies demonstrate the potential therapeutic effect of mindfulness-based interventions in patients with T2D, little is understood about the mode of delivery or quantity of the intervention necessary to experience benefits. This project aims to develop and implement a self-compassion tool kit based on the principles of mindfulness and meditation to better understand how self-compassion works to affect psychological health and wellbeing in patients with T2D. The investigators will study the impact of a self-compassion tool kit - including mindfulness meditation, exercise, journaling and sleep parameters - on T2D. Enhancing emotional well-being could complement current T2D treatments to facilitate improved quality of life. Read Less

Sleep-disordered breathing (SDB or sleep apnea) is very common among elderly Veterans and leads to increased morbidity and mortality in this population. The proposal aims to identity whether oxygen, finasteride and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in the elderly via different mechanisms. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea in the elderly. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea. A cumulative effect of the investigators' research will fulfill the long-term goal of improving the quality of life of elderly Veterans suffering from sleep apnea and its potential life-threatening complications.
