Cognitive problems, like memory loss, are common after brain injuries like trauma or stroke. These problems make daily life harder, and the investigators don't yet know the best ways to help the brain recover. Scientists think that a process in the brain called long-term potentiation (LTP) is important for memory and learning. When LTP isn't working properly, it may cause problems with thinking and memory. But studying LTP in people is hard because it happens deep inside the brain. Our research uses a treatment called electroconvulsive therapy (ECT) to better understand LTP. ECT is a treatment for severe depression that works by causing a controlled seizure in the brain. While ECT often helps depression, it can temporarily cause memory and thinking problems, which usually improve over time. This makes ECT a good way to study how thinking and memory recover. The investigators will use a tool called electroencephalography (EEG) to measure brain activity during different stages of ECT treatment. EEG is a safe and non-invasive way to track changes in LTP. Specifically, the investigators will measure how the brain responds to visual signals using something called visual evoked potentials (VEPs). These signals can show how LTP is affected by ECT. The study's main goal is to track changes in LTP using VEPs during and after ECT. By studying these changes, the investigators hope to learn how ECT affects the brain and how it recovers. This could help improve treatments for brain injuries and other conditions that cause memory and thinking problems. Read Less

This research study is being conducted to develop a brain controlled medical device, called a brain-machine interface. The device will provide people with a spinal cord injury some ability to control an external device such as a computer cursor or robotic limb by using their thoughts along with sensory feedback. Development of a brain-machine interface is very difficult and currently only limited technology exists in this area of neuroscience. Other studies have shown that people with high spinal cord injury still have intact brain areas capable of planning movements and grasps, but are not able to execute the movement plans. The device in this study involves implanting very fine recording electrodes into areas of the brain that are known to create arm movement plans and provide hand grasping information and sense feeling in the hand and fingers. These movement and grasp plans would then normally be sent to other regions of the brain to execute the actual movements. By tying into those pathways and sending the movement plan signals to a computer instead, the investigators can translate the movement plans into actual movements by a computer cursor or robotic limb. A key part of this study is to electrically stimulate the brain by introducing a small amount of electrical current into the electrodes in the sensory area of the brain. This will result in the sensation of touch in the hand and/or fingers. This stimulation to the brain will occur when the robotic limb touches the object, thereby allowing the brain to "feel" what the robotic arm is touching. The device being used in this study is called the Neuroport Array and is surgically implanted in the brain. This device and the implantation procedure are experimental which means that it has not been approved by the Food and Drug Administration (FDA). One Neuroport Array consists of a small grid of electrodes that will be implanted in brain tissue and a small cable that runs from the electrode grid to a small hourglass-shaped pedestal. This pedestal is designed to be attached to the skull and protrude through the scalp to allow for connection with the computer equipment. The top portion of the pedestal has a protective cover that will be in place when the pedestal is not in use. The top of this pedestal and its protective cover will be visible on the outside of the head. Three Neuroport Arrays and pedestals will be implanted in this study so three of these protective covers will be visible outside of the head. It will be possible to cover these exposed portions of the device with a hat or scarf. The investigators hope to learn how safe and effective the Neuroport array plus stimulation is in controlling computer generated images and real world objects, such as a robotic arm, using imagined movements of the arms and hands.

The virological efficacy of ibalizumab has been clearly demonstrated in multiple clinical trials. This study will expand ibalizumab's clinical data set and allow a better understanding of the virologic response durability on ARV regimens with or without ibalizumab in a heterogeneous real-world patient population. Additional data on the efficacy and safety of ibalizumab and its impact on patient reported outcomes will be captured until study end. Primary Objective: To evaluate the long-term efficacy, safety, and durability of ibalizumab in combination with other ARVs by comparing the virologic, immunologic and clinical outcomes of patients receiving ibalizumab treatment versus patients not receiving ibalizumab. Secondary Objective: To assess the efficacy of ibalizumab in combination with other antiretrovirals by comparing the virologic, immunologic, clinical and patient reported outcomes of patients before and after they receive ibalizumab treatment. To assess the long-term safety and tolerability of ibalizumab. Other Objectives: To assess risk factors/predictors of virologic and immunologic response. To assess efficacy and safety in special populations that enroll. Read Less

HIV transmission remains a significant public health concern, especially among men who have sex with men (MSM). Condomless anal intercourse (CAI) continues to be the major route of transmission for MSM. Thus, to reduce the incidence of HIV, it is critical to identify how contextual risk factors influence CAI and develop behavioral strategies that modify risk factors directly or reduce their influence on behavior. This study will examine the mechanisms through which one of the central contextual risk factors, heavy drinking, influences sexual decision processes in the natural environment and test the benefit of a brief intervention designed to reduce sexual risk behavior among those who engage in heavy drinking.

The LIFT will be conducted at Brigham and Women's Hospital (BWH) of Harvard Medical School, focusing on the effect of Pyridostigmine (Mestinon) and Low-Dose Naltrexone (LDN) in subjects aged 18-65 meeting the Canadian consensus criteria (CCC) for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) as well as having specifically Orthostatic Intolerance. This double-blind, placebo-controlled study will involve 160 participants randomized into one of four possible groups: Pyridostigmine/LDN (40), Pyridostigmine/Placebo (40), LDN/Placebo (40), Placebo/Placebo (40). The dose of Pyridostigmine will be carefully titrated from 30mg to 60mg three times a day, and the dose of LDN will be titrated from 1.5 mg to 4.5 mg once daily. The trial includes a scale-back plan, allowing participants to reduce their dosage if they experience intolerance symptoms, with adjustments made during weekly visits. This plan provides a personalized approach to medication tolerance, ensuring participant's safety and comfort throughout the trial. The time commitment for the participant is approximately three (3) months, and during this time, there will be three (3) in-person visits to BWH and four (4) virtual visits. Study procedures will include two (2) submaximum cardiopulmonary exercise tests, questionnaires (virtually completed), and blood and urine collection. We will be recruiting from the BWH Dyspnea Clinic as well as the Open Medicine Foundation (OMF) StudyME Registry and anticipate the entire trial will take two (2) years to complete. The LIFT represents a significant endeavor to improve treatment options for ME/CFS patients and contribute to the broader understanding of this debilitating condition. Read Less
