The goal of this study is to learn if a enhanced environment (Metro Café) with multi model approach (an approach that combines several therapies) in chronic traumatic brain injury improves outcomes of recovery better than traditional therapy. The main questions it aims to answer are: - Determine the amount of therapy dosage (speech, cognition, arm and leg movements) obtained during the Metro Café therapy session. - Evaluate the connection between environmental enrichment dosage (the Metro Café) and clinical outcome scores. Researchers will compare Metro Café Treatment to those who do not receive this treatment to see if better improvements in function after a traumatic brain injury are seen in the Metro Café Treatment Participants will train in the Metro Cafe during the 2-month gap between assessments, for a total of 18 training sessions, each up to 2 hours, 3 times per week. Participants will greet and serve customers drinks and snacks, maintain food supplies at the counters and performs housekeeping tasks with advice and assistance from a supervising researcher as needed,

Crisis Response Planning is an efficacious, one-session intervention that increases positive affect, decreases negative affect and psychiatric hospitalizations, and reduces suicide attempts by 76% among Servicemembers. Crisis Response Planning is hypothesized to reduce suicidality by identifying a variety of personalized strategies that are designed to strengthen and/or promote emotion regulation processes.Research in nonmilitary samples suggests the effectiveness of emotion regulation strategies varies across situations. The applicability of these findings to suicidality among Servicemembers is unknown. Improved understanding of what strategies work under which circumstances and for whom will significantly advance our ability to prevent suicide among Servicemembers. Hypotheses include: 1. Use of self-management strategies, thinking about reasons for living, and seeking social support at time t will be associated with significant reductions in suicidal ideation at time t+1. 2. Use of distraction, reappraisal, and interpersonal emotion regulation strategies at time t will be associated with significant reductions in suicidal ideation at time t+1. 3. Affect intensity and social context will significantly moderate the time-lagged effects of Crisis Response Planning and emotion regulation strategy use on suicidal ideation. 4. Distinct profiles of demographic (e.g., gender, age), historical (e.g., prior suicide attempts), and psychological characteristics (e.g., emotion dysregulation, symptom severity) will predict who experiences a decrease in suicidal ideation following the use of Crisis Response Planning and emotion regulation strategies. 5. (Exploratory): Individuals who utilize their Crisis Response Planning more frequently and perceive Crisis Response Planning as more effective will be more likely to engage in mental health treatment at follow-up.

The goal of this clinical trial is to develop a five-week virtual cognitive training intervention for people with Mild Cognitive Impairment (MCI) based off an existing eight-week intervention. The main question it aims to answer is: • Is five weeks of training as good as eight weeks in improving cognition, quality of life, daily functioning, and mood, and in reducing caregiver burden? Researchers will compare five weeks of cognitive training to eight weeks of training to see if the shorter version is as effective as the full training. Participants will complete all activities virtually: - Complete a screening visit with a study partner (typically a family member, roommate, or close friend) to determine eligibility to participate in the study - Complete some tests of memory and thinking and some questionnaires - Attend weekly two-hour group cognitive training sessions with a trained group leader, for five or eight weeks - Redo the questionnaires and tests of memory and thinking immediately after completing the training, and three months after completing the training

The purpose of this study is to develop and evaluate the usefulness of MRI using 129Xe gas for regional assessment of pulmonary function. Specifically, three forms of 129Xe MRI contrast will be the investigators focus - 1) imaging of the 129Xe ventilation distribution, 2) imaging the alveolar microstructure via the 129Xe apparent diffusion coefficient (ADC), and 3) imaging 129Xe that dissolves in the pulmonary blood and tissues upon inhalation. Such imaging of 129Xe gas transfer is expected to be uniquely sensitive to pathologies affecting gas exchange (fibrosis, emphysema, pulmonary hypertension) and provide new insights regarding the normal resting heterogeneity of pulmonary gas exchange.

The goal of this study is to determine how a drug class called glucagon-like peptide-1 receptor agonists (GLP-1Ra) affects people during an early stage of Type 1 Diabetes undergoing clinical teplizumab treatment. This study involves giving participants a liquid meal under different conditions and observing how their bodies respond, focusing on blood sugar levels, insulin effectiveness, and blood vessel function. The meal tests are followed by two post-treatment tests, one with the GLP-1Ra drug and the other with a placebo. Each test involves blood draws before and during the meal test, GLP-1Ra or placebo administration, and an ultrasound to measure blood vessel function. The goal is to see if GLP-1Ra can help manage blood sugar levels and improve cardiovascular health in this population.

The 5-year K01 Mentored Research Scientist proposal will employ brain, neurocognitive, and computational tools (e.g., machine learning) to understand the impact of opioid-use disorder (OUD) and common co-occurring issues on executive function and clinical outcomes. There have been record numbers of fatal and non-fatal overdoses (ODs) associated with opioids (and other drugs) in the past 12-months. Improving classification and predictive capabilities to enhance treatment and prevent relapse is of the upmost importance. Deficits in neurocognition often are associated with poor treatment outcomes (e.g., more drug use, medication non-adherence), yet co-occurring issues associated with OUD (e.g., depression, anxiety, physical/sexual abuse, neglect) make it difficult to parse which contributing factors lead to worse executive function (EF) and poorer treatment outcomes. Novel brain, neurocognitive, and computational tools are needed to help determine these differences, in order to lay the foundation for better treatments. This need has shaped both the training plan and the associated research project in a 5-year K01 Mentored Research Scientist proposal, building on Dr. Regier's prior preclinical and clinical addiction neuroscience experience (focused mostly on cocaine-use disorders, cue-reactivity, subcortical networks, prior adversity, and univariate imaging techniques).

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 18-70 meeting the Canadian consensus criteria (CCC) for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) as well as having specifically Orthostatic Intolerance (OI). Long COVID (LC) subjects will also be included if they meet CCC and have OI. 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.

In this study the investigators are proposing to evaluate the efficacy, sustainability, and mechanisms of 3 months of individualized counseling of the FRD delivered by registered dietitians, over 8 sessions by phone/video conferencing on fatigue, quality of life, and associated symptoms in persistently fatigued lymphoma cancer survivors compared to 3 months of individualized counseling of the attention control (matched for time and frequency of interactions with the FRD) the General Health Curriculum (GHC). The investigators will randomize and follow 68 lymphoma cancer survivors; accounting for a ~10% drop out rate to achieve a target of 60 patients that will complete the study. The investigators hypothesize that persistently fatigued lymphoma cancer survivors will experience improvements in fatigue, quality of life, and symptoms commonly associated with fatigue, which are then maintained at 15-months post-enrollment; and decreased CRP and alterations in inflammation-associated DNA methylation consistent with reduced inflammation from following the FRD as compared to the GHC.
