The investigators have designed a pragmatic trial of home-based transcranial direct current stimulation (tDCS) for phantom limb pain (PLP), the PLP-EVEREST trial (PLP-EffectiVEness pRagmatic Stimulation Trial) to test a portable device that would reach underrepresented populations and would validate this therapy in a more pragmatic setting. Subjects will be randomized to home-based tDCS of the primary motor cortex (M1) with somatosensory training or usual care only (including their current pharmacological treatments, physical therapy, and occupational therapy). The investigators will therefore test the effectiveness of home-based tDCS and somatosensory training in a real-world, home-based setting. The Investigator will compare patients randomized to this combined strategy vs. usual care alone (subjects from this group will be offered combined treatment at the end of the trial). The investigators hypothesize that the combined strategy will be associated with a significantly larger Cohen's d effect size (at least 1) compared to the control group.

With an incidence rate of about 1%, Anorexia Nervosa (AN) is a serious mental disorder associated with high mortality, morbidity, and cost. AN in youth is more responsive to early treatment but becomes highly resistant once it has taken an enduring course. The first-line treatment for adolescents with AN is Family Based Treatment (FBT). While FBT can be delivered using videoconferencing (FBT-V), therapists' limited availability hampers scalability. Guided self-help (GSH) versions of efficacious treatments have been used to scale and increase access to care. The main aim of this proposed comparative effectiveness study is to confirm that clinical improvements in GSH-FBT are achieved with greater efficiency than FBT-V in generalizable clinical settings.

This is a double-blind, 2-group randomized controlled trial evaluating the effects of topiramate versus placebo in patients with comorbid PTSD and moderate-to-severe AUD. This trial will provide one of the first rigorous tests of whether the effects of topiramate in AUD generalize to patients with co-occurring PTSD, and one of the first rigorous tests of whether topiramate has beneficial effects on PTSD symptoms in this population. It will be the first study to test whether the rs2832407 genotype predicts clinical response to topiramate for AUD and PTSD in patients with both disorders. Further, it will contribute to the understanding of topiramate's mechanisms of action in the co-morbid AUD/PTSD population, and to the discovery of predictors of treatment response.

This study meets the NIH definition of a clinical trial, but is not a treatment study. Instead, the goal of this study is to investigate how hearing ourselves speak affects the planning and execution of speech movements. The study investigates this topic in both typical speakers and in patients with Deep Brain Stimulation (DBS) implants. The main questions it aims to answer are: - Does the way we hear our own speech while talking affect future speech movements? - Can the speech of DBS patients reveal which brain areas are involved in adjusting speech movements? Participants will read words, sentences, or series of random syllables from a computer monitor while their speech is being recorded. For some participants, an electrode cap is also used to record brain activity during these tasks. And for DBS patients, the tasks will be performed with the stimulator ON and with the stimulator OFF.

This research study is called 'PRenatal and Obstetric Maternal Exposures and ISlet Autoantibodies in Early Life: The PROMISE Study'. The purpose of this study is to find out more about how exposures during pregnancy, such as having an infection, diet and growth may impact later risk of type 1 diabetes (TID) and islet autoimmunity in the child. We are also interested in finding out more about why having a father or sibling with T1D increases risk of autoimmunity in the child more than having a mother with T1D. We are enrolling women who are pregnant and either have T1D or another first degree relative (father or full sibling) of the baby has T1D. The biological father is also invited to enroll in study, as it is important to understand how the father's health and genetics may contribute to the child's risk of developing T1D. The study procedures for the mother, father and baby are explained below. Mother: Pregnant women will be asked to complete a visit once per trimester (3 visits) during pregnancy and one visit up to 12 weeks after delivery. At each visit, mothers will consent to a blood draw, collection of biological samples and the completion of questionnaires. . Mothers who have T1D will also be asked to download any diabetes device data they have, such as continuous glucose monitor or insulin pump data. Father: The (biological) father will be invited to enroll in a single visit. He will consent to a blood draw and completion of questionnaires. Fathers with T1D will also be asked to download any diabetes device data they have, such as continuous glucose monitor or insulin pump data. Baby: The baby will have blood collected at birth to determine the genetic risk for T1D. Families will consent to the completion of questionnaires about growth, health and diet at 6, 12, 18 and 24 months of age and between 5-7 years of age, and to complete blood testing for islet autoantibodies at 24 months and between 5-7 years of age. For those children with a high genetic risk score, we will also collect blood for autoantibody testing at 6, 12, and 18 months of age.
