The Computerized Registry of Patients with Venous Thromboembolism (RIETE) is a multidisciplinary Project initiated in march 2001 and consisting in obtaining an extensive data registry of consecutive patients with venous thromboembolism. The main objective is to provide information on the Internet to help physicians to improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy, extreme body weight, etc), with the purpose of decreasing mortality, frequency of thromboembolic recurrences as well as bleeding complications and arterial events. As an additional objective RIETE is also aimed to create predictive scores that help physicians to better identify patients with high risk of presenting some of these complications. The primary parameters recorded by the registry comprise details of each patient's clinical status, including any coexisting or underlying conditions, and the type, dose, duration and outcome (during the first 3 months of therapy) of antithrombotic treatment. Study endpoints are clinically recognized (and objectively confirmed) recurrences of VTE, major and minor bleeding complications, and death.

This project is a single center, prospective randomized controlled trial (N=198) primarily evaluating the efficacy of the Survivorship Sleep Program vs. Enhanced Usual Care on insomnia severity among cancer survivors. The investigators will also examine secondary outcomes associated with cancer-related insomnia including subjective and objective sleep measures (i.e., sleep diaries, actigraphy), emotional distress, fatigue, and use of sleep medications. Notably, most CBT-I trials with cancer survivors who have completed primary treatment with curative intent (i.e., curvivors) but not those in treatment or living with metastatic cancer (i.e., metavivors). To enhance generalizability, this RCT will stratify enrollment by survivorship phase (1:1:1). This project in strengthened by partnerships with community organizations (SurvivorJourneys and Ellie Fund) and use of both quantitative (i.e., surveys, actigraphy) and qualitative methods (i.e., interviews) to inform considerations for future implementation. Collectively, the proposed project will yield multiple deliverables to innovate cancer survivorship care, namely an efficacious, virtually delivered intervention addressing chronic insomnia, one of the most deleterious concerns among the growing population of cancer survivors in the US. Findings will inform a future effectiveness trial and the expansion of the synchronous delivery of CBT-I to survivors across different phases of cancer survivorship.

This study originally included 140 subjects with medication-refractory depression undergoing 10 Hz transcranial magnetic stimulation (10Hz-TMS) to the left dorsal lateral prefrontal cortex (DLPFC), with the goal of having 60 completers with good quality data. Subjects were recruited from the TMS clinics at Beth Israel Deaconess Medical Center, Brigham & Women's Hospital, and Butler Hospital. Subjects underwent an hour-long MRI scanning session, an optional DNA-sample collection, up to three 20 minute neuronavigation sessions for marking the site of TMS stimulation, questionnaires, and a behavioral testing battery before and after their TMS treatment course. The task battery included the Emotion Conflict Resolution (ECR) task, Multi-Source Interference Task (MSIT), War Game (Gambling) task, and Associative Learning with Reversal task. Subjects' scores on the Quick Inventory of Depressive Symptomatology (QIDS) and Beck Depression Inventory (BDI) were assessed before and after the TMS course. MRI data was utilized to identify brain regions whose connectivity to the stimulation site co-varies with the aforementioned measures of symptom improvement. This was the only study group until August 30, 2022, and the primary outcome was analyzed for the 10Hz-TMS group. Due to changes in clinical standard of care from 10Hz-TMS to a newer version of TMS termed intermittent theta burst (iTBS), in September 2022 a second group was added to include patients receiving this new form of TMS. This second group included another 100 patients with medication-refractory depression undergoing iTBS to the left dorsal lateral prefrontal cortex (DLPFC), with the intent to have 80 completers. Massachusetts General Hospital was added as a data collection site in lieu of Butler Hospital. Subjects will undergo an hour-long MRI scanning session, up to three 20 minute neuronavigation sessions for marking the site of TMS stimulation, questionnaires, and a behavioral testing battery before and after their TMS treatment course. The task battery will included the Emotion Conflict Resolution (ECR) task, Multi-Source Interference Task (MSIT), Penn Emotion Recognition Test, the Suicide/Death Implicit Association Test, and Associative Learning with Reversal task. Subjects' scores on the Beck Depression Inventory (BDI) were assessed before and after the TMS course. MRI data will be utilized to identify brain regions whose connectivity to the stimulation site co-varies with the aforementioned measures of symptom improvement. Due to a higher dropout rate than anticipated, in March of 2025 an amendment was added to include an additional 20 subjects in the second group's enrollment goal to increase the likelihood of achieving 80 completers.

In this research study we want to learn more about the effects of non-invasive brain stimulation on memory and brain-network function in cognitively unimpaired older adults and in patients with amnestic mild cognitive impairment (aMCI). This study will use a form of non-invasive brain stimulation called repetitive Transcranial Magnetic Stimulation (rTMS). rTMS will slightly alter activity in an area of your brain that controls memory. Changes resulting from this stimulation will be measured with behavioral tests of memory and general cognition, as well as by taking images of your brain with Magnetic Resonance Imaging (MRI). Participants will come in for one baseline visit followed by 10 days of daily rTMS study visits (Monday through Friday) and an evaluation visit. Then, there will be a 2-week break. After this break, they will return for another baseline visit, an additional 10 days of rTMS, and a final evaluation visit.
