The goal of this observational study is to evaluate the feasibility of using wearable sensor and digital technologies to measure motor and speech function in adults with autoimmune Myasthenia Gravis (MG). The main question[s] it aims to answer are: - To measure the correlation of sensor-based measures of motor function with existing outcome measures including the MG-ADL, MGQOL15r, QMG, MGComposite, and Neuro-QOL Fatigue scales. - To develop and validate tablet-based digital assessments of speech and facial expression and to compare with existing outcome measures. Participants will wear a pendant sensor for 7 days and then participate in tablet-based and in-person myasthenia-specific physical examinations. This will be performed in concert with routine care in the Massachusetts General Hospital MG clinic.

The SUPRAMAX Study: Supramaximal Resection Versus Maximal Resection for High-Grade Glioma Patients1

A greater extent of resection of the contrast-enhancing (CE) tumor part has been associated with improved outcomes in high-grade glioma patients. Recent results suggest that resection of the non-contrast-enhancing (NCE) part might yield even better survival outcomes (supramaximal resection, SMR). Therefore, this study evaluates the efficacy and safety of SMR with and without mapping techniques in HGG patients in terms of survival, functional, neurological, cognitive, and quality of life outcomes. Furthermore, it evaluates which patients benefit the most from SMR, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 2-arm cohort study of observational nature. Consecutive HGG patients will be operated with supramaximal resection or maximal resection at a 1:3 ratio. Primary endpoints are: 1) overall survival and 2) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months postoperatively. Secondary endpoints are 1) residual CE and NCE tumor volume on postoperative T1-contrast and FLAIR MRI scans 2) progression-free survival; 3) onco-functional outcome, and 4) quality of life at 6 weeks, 3 months, and 6 months postoperatively. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).

This is a single-center pilot study to be conducted at Massachusetts General Hospital. The purpose of this study is to examine the non-pharmacological impact of Cognitive Behavioral Therapy (CBT) on gastroparesis symptoms and other clinical co-comorbidities such as pain, depression, anxiety, and catastrophizing. CBT trial patients will undergo careful phenotyping pre- and post- intervention with brain MRI, autonomic function test (AFT), gastric emptying scintigraphy (GES), and nutrient drink test (NDT) to determine the impact of CBT on these metrics in patients with gastroparesis. Characterization of these relationships or lack thereof can help guide future development of more targeted approaches and optimize treatment strategies for gastroparesis.

The investigators aim to conduct a fully powered randomized controlled trial to compare the efficacy of two symptom management programs for older adults with early cognitive decline (either self-reported or confirmed by testing) and chronic pain, Active Brains 1 and Active Brains 2. The investigators will assess how each program may help in improving multimodal physical, cognitive and emotional function. The investigators will also assess whether improvements in outcomes from the two programs are maintained through 6-months follow-up. The investigators will also explore whether improvements in outcomes are mediated by nonadaptive pain reactions, adaptive coping, social factors and compensatory strategies and modified by demographic and clinical predictors. Both programs will be delivered virtually (Zoom).

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.
