This clinical trial studies cognitive function in men with prostate cancer treated with androgen receptor directed therapies such as abiraterone acetate and enzalutamide. The investigators use MRI imaging (non-invasive, non-contrast) to see whether there are changes in brain structure or activity related to treatment that may be related to changes in cognitive function. The investigators are also looking for genetic variations that might make patients more or less sensitive to cognitive changes during treatment for prostate cancer.

Thoracentesis is a very common procedure, rarely associated with severe complications. One relatively common complication is chest discomfort, which is most of the time felt to be secondary to negative pleural pressures generated during the procedure. While most proceduralists use suction to drain the pleural fluid, some drain effusions by gravity only. The investigators propose to evaluate whether gravity-driven thoracentesis results in less discomfort for patients than suction-drive thoracentesis.

This screening and multi-sub-study randomized phase II/III trial will establish a method for genomic screening of similar large cancer populations followed by assigning and accruing simultaneously to a multi-sub-study hybrid ?Master Protocol? (S1400). The type of cancer trait (biomarker) will determine to which sub-study, within this protocol, a participant will be assigned to compare new targeted cancer therapy, designed to block the growth and spread of cancer, or combinations to standard of care therapy with the ultimate goal of being able to approve new targeted therapies in this setting. In addition, the protocol includes a ?non-match? sub-study which will include all screened patients not eligible for any of the biomarker-driven sub-studies. This sub-study will compare a non-match therapy to standard of care also with the goal of approval.

Injection of OnabotulinumtoxinA (BTX-A) into the bladder is a widely used treatment option for patients with overactive bladder who have failed medical therapy. Urinary tract infection is the most common side effect of this procedure and therefore antibiotics are given around the time of injection in order to prevent these events. While antibiotics are commonly given at the time of injection, the duration of these antibiotic regimens are variable. The investigators propose a study to investigate different antibiotic protocols and their affect on the rate of urinary tract infection after injection.

Low carbohydrate diets such as the ketogenic (KD) and low glycemic index (LGIT) diets have been shown to be effective in treating drug resistant seizures in children with Angelman syndrome (AS). The investigators hypothesize that consuming a fat based nutritional formulation with an exogenous ketone throughout the day will produce urinary ketosis in children consuming both low and high carbohydrate diets, depending upon dietary background. The nutritional formulation will provide fuel substrates that push metabolism away from carbohydrates and towards fat utilization. This research is being done to assess the safety and tolerability of a nutritional formulation for use in dietary interventions in AS.

This partially randomized phase III trial is studying maintenance chemotherapy to see how well it works compared to observation following induction chemotherapy and radiation therapy in treating young patients with newly diagnosed ependymoma. Drugs used in chemotherapy, such as vincristine sulfate, carboplatin, cyclophosphamide, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving chemotherapy with radiation therapy may kill more tumor cells and allow doctors to save the part of the body where the cancer started.

It can be difficult to achieve remission in individuals with late-life depression (LLD) and they often require aggressive treatment. This challenge is in part due to age-related vascular changes that are common in LLD. Successful antidepressant treatment involve changes across affective, cognitive, and default mode networks. We hypothesize that in LLD, vascular disease adversely affects response to antidepressants by disrupting connectivity of these networks. The primary goal of this project is to characterize how focal vascular damage affects regional connectivity and response to antidepressants. Based on past work and pilot data, we a priori focus on the cingulum bundle and uncinate fasciculus. These key fiber bundles connect frontal, temporal, and cingulate regions involved in cognition and affective responses. Our central hypothesis is that ischemic damage to the cingulum bundle and uncinate fasciculus contributes to structural and functional connectivity deficits of those tracts. This results in a disconnection effect that alters the function of connected regions. In turn, this increases the risk of a poor response to antidepressants. Our approach is to enroll up to 130 adults over age 60 years with a diagnosis of Major Depressive Disorder. Subjects will complete clinical evaluation, cognitive testing, and MRI/functional MRI (fMRI) sessions, including an fMRI emotional oddball task that includes attentional and affective components. Participants will be stratified by cerebral lesion severity and randomized in a 2:1 ratio to a double-blinded 8-week trial of escitalopram or matching placebo. Those who do not remit will transition to an 8-week trial of open-label bupropion, an antidepressant with a different mechanism of action. This will allow us to determine if different and distinct circuit deficits affect response to antidepressants with different mechanisms of action while also accounting for the placebo response.

Vanderbilt University Medical Center is one of the largest-volume DBS centers in the country. From 2007 through October 2017, 265 Parkinson's disease (PD) patients underwent deep brain stimulation (DBS), 168 of those implanted in subthalamic nucleus (STN) and 97 in globus pallidus interna (GPi). Pre-operatively, each patient is extensively evaluated with a battery of validated motor, cognitive, and mood instruments. This information is stored in RedCAP, a secure online database platform. In an attempt to capture longitudinal outcomes in this population of interest, we will recruit all PD patients two years or more status post DBS who are receiving regular care at Vanderbilt University Medical Center. Study participants will undergo a condensed evaluation of motor function (Unified Parkinson's Disease Rating Scale Part III), cognitive performance (Mini-Mental Status Examination), mood (Beck Depression Inventory), and quality of life (Parkinson's Disease Questionnaire-39). These results will be compared to baseline measures performed pre-operatively, allowing for assessment of interval change. STN and GPi DBS patients will be analyzed separately.

The investigators' overarching goal is to improve long-term outcomes for end stage renal disease (ESRD) patients. In this study we focus specifically on patients receiving peritoneal dialysis (PD). Volume regulation in PD patients is related to hypertension, heart failure, nutritional status, and survival. Salt (NaCl) is the body's ion transport target to normally regulate volume via the kidneys; however, in hemodialysis (HD) patients the dialyser or in PD patients the peritoneal membrane, must serve that purpose. Determining volume status in PD patients is not easy and monitoring sodium (Na+) is more difficult still. The investigators have developed a novel, noninvasive approach to this problem involving 23Na+ magnetic resonance imaging (Na-MRI). Na+ is stored bound to proteoglycans in mostly the skin. Our technique measures Na+ in skin and skeletal muscle. In this study, we propose to apply this novel technique to PD patients. Aim 1. To determine Na+ stores in PD patients, to compare Na+ stores to normal controls using Na-MRI technique, and to correlate Na+ stores by Na-MRI with multifrequency bioimpedance measurements and cross-sectional clinical data. Hypothesis: Na+ stores are increased in PD patients compared to normal controls; they are increased in PD patients with volume expansion and in those patients with high soluble vascular endothelial growth factor receptor-3 (sFlt-4) levels. Aim 2. To determine the utility of Na-MRI as an assessment of preserving residual renal function in PD patients. Hypothesis: Extracellular volume expansion as measured by multifrequency bioimpedance was found to have no utility in predicting preservation of residual renal function in PD patients. The investigators hypothesize that Na+ stores as determined by 23Na-MRI will fulfill that function and will be inversely, rather than directly, related.

Patients with POTS experience significant gastrointestinal symptoms. Current evidence suggesting that abnormal post-ganglionic sympathetic function could play a role in the pathophysiology of these GI abnormalities. Sympathetic fiber regulate motor and the postprandial GI peptides secretion. The focus of the present proposal is to determine glucose homeostasis, GI motility, and their association with GI and cardiovascular symptoms in POTS patients versus healthy controls. Furthermore, we will determine differences in these outcomes in POTS patients with and without evidence of postganglionic sympathetic fiber neuropathy. As a long-term goal, this study can lead us to understand the pathophysiology of common co-morbidities in patients with POTS to provide new treatment approaches and prevention strategies.

Neuromuscular blocking drugs (NMBDs) provide anesthesiologists with powerful intraoperative tools, but their use carries the potential risk of serious postoperative complications. NMBD-induced muscle weakness that lingers into the postoperative period, known as postoperative residual curarization (PORC), is present in as many as 40% of all patients that receive neuromuscular blocking agents. The Post Anesthesia Care Unit will be introducing monitoring as part of standard of care. This study will collect data about patients who receive NMBDs and examine the impact of monitoring on incidences of PORC. Our study is designed to test the following hypotheses: Hypothesis 1: The initiation of quantitative TOF monitoring as part of the standard PACU entry evaluation will change practitioner behavior in a manner that decreases the incidence of PORC in surgical patients at VUMC. Hypothesis 2: The initiation of the routine TOF monitoring program will decrease the incidence of short- and long-term postoperative complications at VUMC.
