This phase II trial studies how well surgery works in preventing ovarian cancer in patients with genetic mutations at risk of ovarian cancer. Risk reducing salpingo oophorectomy (RRSO) is surgery to remove the fallopian tubes and ovaries at the same time. Interval salpingectomy with delayed oophorectomy (ISDO) is surgery to remove the fallopian tubes. It is not known whether ISDO works better than RRSO at lowering risk of ovarian cancer and improving the sexual function and psychosocial well-being in patients with genetic mutation.

The purpose of this study is to identify individuals 18 or older who have diagnostic presentation of adhesive capsulitis and randomize them into two arms, distinguished by use of physical therapy and steroid injections compared with steroid injections followed by watchful waiting. This prospective study will be used to determine whether there is a significant impact on patient outcome and whether the additional financial burden is justified. There are no experimental interventions for this study. The use of physical therapy, oral and parenteral corticosteroids, and watchful waiting are offered following the standard of care for adhesive capsulitis. Our hypothesis is that patients will not have a significant difference in outcome between the two study arms. One group will undergo regular physical therapy with corticosteroid injections (Arm 1) and the other will have steroid injections during the inflammatory phase only and then be regularly observed (Arm 2). We also hypothesize there will be a significant financial burden associated with the PT arm that is not justified with the possibility of increased symptom reports in that arm.

The management of chronic pain is a significant public health issue related to escalating treatment costs, lost productivity, disability and medication use. The prevalence of chronic pain is rising alarmingly across all subpopulations with chronic low back pain (LBP) being labeled as one of the 15 most expensive medical conditions. Both study investigators are involved in the medical treatment of these patients. The investigators are interested in testing the effectiveness of alternative treatment strategies that address the complexity of chronic pain that is often mediated not only by physiologic variables, but also psychosocial issues. There is emerging evidence that Virtual Reality (VR) may be an effective pain management tool to augment care in this population, reducing medical costs, decreasing medication use, improving outcomes and empowering patients to take more control over their own health and management of chronic pain. Less is known about the use of this technology delivered in the context of care delivered in an outpatient clinical setting.

Screening for breast cancer improves early detection of aggressive cancers and has been shown to reduce breast cancer related mortality. Currently, mammography is the most effective way of detecting early stage, non palpable breast cancers. However, mammography only reveals the breast structure, and cannot say much about the breast physiological state. We propose Tomographic Optical Breast Imaging (TOBI) as an inexpensive, patient friendly technique that is non-invasive and does not use non-ionizing radiation. TOBI uses near infrared light and by measuring how such light passes through the breast, images of blood volume and hemoglobin oxygenation can be obtained. In this study, TOBI is combined with digital breast tomosynthesis (DBT, a form of 3D mammography) and our hypothesis is that the TOBI-DBT combined images can be used to diagnose breast cancer with significantly improved sensitivity and specificity compared to DBT alone.

Functional Neurological Disorder (FND/ Conversion Disorder) is a highly prevalent and disabling neuropsychiatric condition. Motor FND symptoms include Functional Movement Disorders (FMD) and Functional Weakness and Psychogenic Nonepileptic Seizures (PNES).Though patients with FND present with a wide variety of symptoms, FMD, PNES, and functional weakness may be viewed as overlapping conditions lying along a phenotypic spectrum for a single disorder. Patients with FND frequently present with psychiatric symptoms, including depression, anxiety, Borderline Personality Disorder, and Post-Traumatic Stress Disorder, alongside their physical symptoms. To treat these symptoms, patients with FND are frequently enrolled in physical therapy and cognitive behavioral therapy, which are considered usual care for FND at our center. Developing a further understanding of treatment outcome, including biomarkers of clinical improvement and psychometric factors associated with treatment response, could inform future interventions and better tailor treatments to patients with specific FND symptom profiles. We hypothesize that treatment response will be associated with structural and functional alterations in salience network regions and that more adaptive neuropsychiatric profiles at baseline will predict a positive treatment outcome.

Functional Neurological Disorder (FND/ Conversion Disorder) is a highly prevalent and disabling neuropsychiatric condition. Motor FND symptoms include Nonepileptic Seizures, Functional Movement Disorders and Functional Weakness. Clinical research across these motor FND subtypes, including research studies from the candidate's laboratory, suggest that these populations share many clinical and phenotypic similarities that warrant increased research integration. Furthermore, despite the prevalence of motor FND, little is known about the underlying neuropathophysiology of this condition, which is a prerequisite for the development of biologically informed prognostic and treatment response biomarkers. Across 3 published neurobiologically focused articles, the candidate proposed a framework through which to conceptualize motor FND. It is suggested that motor FND develops in the context of structural and functional alterations in neurocircuits mediating emotion awareness/expression, bodily awareness, viscerosomatic processing and behavioral regulation. The overall goal of this project is to comprehensively investigate structural and functional magnetic resonance imaging (MRI) biomarkers of prognosis across motor FND. Multimodal structural and functional MRI techniques (including voxel-based morphometry, cortical thickness, resting-state functional connectivity and diffusion tensor imaging tractography) will be used to systemically probe brain-prognosis relationships. Novel aspects of this proposal include the study of the full spectrum of motor FND, consistent with a trans-diagnostic approach.

Patients with end stage renal disease (ESRD) usually have high levels of urea that may interact with blood proteins and change their structure by a process known as carbamylation. Evidence suggests that high levels of carbamylated proteins may be linked to adverse outcomes in dialysis patients. This is a randomized, open-label study to evaluate the effects of amino acid supplementation on levels of carbamylated proteins in ESRD patients. Secondary objectives will be to determine whether this intervention can modify intermediate markers of inflammation, cardiac stress, and erythropoietin responsiveness in this population. Sixty ESRD patients on dialysis will be randomized into two groups of 30 patients each. Group 1 will receive intravenous supplementation with an FDA-approved amino acid solution (250 mL of NephrAmine®, 5.4% amino acids) during regular dialysis sessions (3 times weekly for 8 weeks); Group 2 will be treated according to standard-of-care (no amino acid supplementation). During the 8 weeks of therapy and for 4 weeks of follow-up, blood will be drawn from patients' existing hemodialysis access ports (~20 mL once per month) to measure levels of carbamylated albumin, amino acids, selected biomarkers, and standard laboratory values. Patients randomized to Group 1 will have fluid volume equivalent to the amino acid therapy removed by ultra-filtration to avoid net fluid gain. All patients will be monitored for safety (adverse events) and for changes in hemodynamics and dialysis prescription.

This phase II trial studies how well radiation therapy works when given with gemcitabine hydrochloride and cisplatin work in treating patients with squamous cell cancer of the vulva that has spread from where it started to nearby tissue or lymph nodes. 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. Drugs used in chemotherapy, such as gemcitabine hydrochloride 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 radiation therapy together with gemcitabine hydrochloride and cisplatin may kill more tumor cells.

The study is proposed as a single-site randomized double-blind placebo-controlled trial requiring 4 study visits, where two of the visits are combined with their appointment for routine clinical care. The study population will consist of patients with quiescent CD and UC and IBD-unspecified recruited from the Massachusetts General Hospital Crohn's and Colitis center. All eligible subjects will have a confirmed diagnosis of CD, UC, or IBD-unspecified according to accepted clinical, endoscopic, radiologic, and histologic criteria. Eligible patients will be contacted at the time of their routinely scheduled office visit and consented for the study. Self-report and review of medical records will be used to obtain detailed information regarding their disease on an intake questionnaire completed by a research study coordinator. The study is proposed as a 12-week double-blind randomized controlled trial of the probiotic supplement compared to placebo. We propose to examine the effect of a specific probiotic supplement on the changes in the gut microbiome, serum metabolomic profile, and fatigue symptoms in patients with quiescent IBD. Within 2 weeks of screening, eligible patients will be invited to visit MGH for a baseline visit. The patient will receive either the probiotic supplement or placebo for 4 weeks. The first follow up visit will be at week 4 to check for adverse events on study treatment, to check accountability of probiotics/placebo, and to complete the set of questionnaires. Also, subjects will receive probiotic/placebo samples for the remaining 8 weeks of treatment. At week 8, subjects will receive a phone call from a study research coordinator to check in with probiotics/placebo intake for treatment compliance and accountability records, and to complete the set of questionnaires ascertaining subjective symptoms. Last study visit will be at week 12 which is often combined with a regular office appointment. Subject will provide serum blood and stool sample, as well as complete the set of questionnaires.

The investigators propose a test of causality by examining a cohort of patients undergoing deep brain stimulation (DBS) within the ventral striatum. The investigators will examine behavior on and off stimulation across a range of tasks that index different forms of impulsivity. Patients will be studied in both the ON and OFF state - that is, they will be tested during active deep brain stimulation and 30 min to 1 hour after stimulation has been stopped (order of state will be counterbalanced across subjects). The investigators specific aim is to test the hypothesis that enhancing ventral striatal signaling (i.e. ON-state DBS) will cause more impulsive patterns of behavior across several impulsivity tasks. The investigators predict that ventral striatal DBS will increase stop-signal reaction time on the stop-signal task and commission errors on the Go/NoGo task, and increase delay aversion in a delay discounting paradigm.
