Purpose: To establish a whole food, egg, as a viable study material to supplement mothers and infants with nutrients that support optimal brain development. There will be 84 breastfeeding dyads, 3 months postnatal. Mothers will be randomized to a whole egg or egg white (due to lack of an appropriate control food). Initial diet intake will be screened using the NDSR. Participants will come to the lab 3 times across 3 months (age 3 months, 4.5 months, and 6 months). Milk, saliva, and plasma will be collected from the mother, while saliva and plasma (heel stick) are collected from the infant. Diet data will be collected at each visit. The infant will complete a recognition memory test using electrophysiology at 6 months as well as the Bayley Scales of Infant Development at 4.5 months. The mother will complete a temperament questionnaire at 3 months and 6 months.

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.

Type 2 diabetes (T2D) affects the ability of the body to process glucose (sugar). Under fasting conditions, the liver is able to make sugar to maintain glucose levels in an important process called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to regulate levels of glucose in the body by communicating with the liver. This process can be impaired in people with type 2 diabetes, and can contribute to the high level of glucose seen in these individuals. The purpose of this study is to understand how activating control centers of the brain with a medication called diazoxide can affect how much glucose (sugar) is made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn can lead to diabetes complications.

A single subanesthetic dose infusion of the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has rapid and robust antidepressant effects in patients with treatment-refractory major depressive disorder (TRD). A family history of an alcohol use disorder (Family History Positive, FHP) is one of the strongest identified predictors of an improved antidepressant response to ketamine. Like ketamine, alcohol is a functional NMDA receptor antagonist. FHP is associated with differential response to ketamine, e.g. blunted psychotomimetic side effects. One of the primary mechanistic hypotheses for ketamine's antidepressant action is the acute intrasynaptic release of glutamate from major output neurons, e.g. cortical pyramidal cells. Preliminary clinical studies have demonstrated this acute glutamate "surge" in response to subanesthetic dose ketamine. Based on these findings, the investigators hypothesize that ketamine's enhanced antidepressant efficacy in FHP TRD subjects is, at least in part, attributable to increased glutamate release relative to TRD subjects without a family history of alcohol use disorder (Family History Negative, FHN). To test this hypothesis, the investigators have designed a now two-site, open-label study of 18-55-year-old medically and neurologically healthy, currently moderately-to-severely depressed TRD patients. In total, the investigators plan to recruit 25 FHP and 25 FHN TRD subjects. All subjects must not have a current substance use disorder (except nicotine or caffeine). The experimental portion consists of two phases. The preliminary first phase is a medication taper (if needed) and psychotropic medication-free period. The experimental second phase comprises one subanesthetic dose (0.5mg/kg x 40 minute) ketamine infusion. The ketamine infusion will occur during 7T-magnetic resonance imaging (MRI), both resting-state functional MRI (rs-fMRI) and magnetic resonance spectroscopy (MRS) to detect glutamate in the ventromedial prefrontal cortex/ventral anterior cingulate cortex (vmPFC/vACC). The primary outcome measure is group mean change in Montgomery-Åsberg Depression Rating Scale (MADRS) score from pre-ketamine infusion (baseline) to one-week post-infusion, where the investigators observed ketamine's greatest antidepressant effect in FHP TRD. Additional outcome measures are vmPFC/vACC glutamate change in response to ketamine based on family history status. In summary, this study will provide key mechanistic information on ketamine's improved antidepressant efficacy in a biologically-enriched subgroup. This will contribute to the systematic development of more efficacious, personalized treatments for major depression in an effort to reduce its enormous public health burden.

The American Academy of Pain Medicine has labeled pain as a "silent epidemic" due to its staggering costs to society (over $500 billion/year) and widespread prevalence (affects over 100 million Americans). Thus, it is imperative to test and validate cost-effective pain therapies. To this extent, cannabis is characterized as one of the most promising therapies to treat a wide spectrum of pain conditions. However, the clinical applicability of cannabis-based pain therapies has been limited due to lacking mechanistic characterization in human-focused studies. Of critical importance, the neural mechanisms supporting cannabis induced pain relief remain unknown. The primary objective of the proposed pilot study is to identify the brain mechanisms supporting the direct alleviation of acutely evoked pain through vaporized cannabis.

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.

This study will determine whether electrical stimulation of an area of the brain called the dorsolateral prefrontal cortex, which is important in determining the feeling of fullness after eating, affects how much food a person eats and weight loss over 4 weeks. It will also compare weight changes in people who attend weight loss counseling sessions and those who do not over this period of time. Obese, non-diabetic people between 18 and 60 years of age who are in good health and who live in the Phoenix, AZ, metropolitan area are eligible for this study. Candidates must have a body mass index of 35 kg/m(2) or more and weigh less than 350 pounds. Participants are admitted to the NIH inpatient unit in Phoenix for the first 9 days of the study for tests, which include meal tests to determine eating behaviors and caloric intake, blood and urine tests, glucose tolerance test, weight measurement, psychological assessments and DEXA scan to measure body fat. For 3 of the days, they will be asked to eat all of their food from automated vending machines. Some subjects receive transcranial direct current stimulation (TDCS). For this procedure, electrodes that conduct electricity are placed on the head and arm and the current is turned on for 40 minutes. Some tingling may be felt under the electrodes. Other subjects receive sham TDCS, with the current turned on only very briefly. After the evaluations, subjects are discharged home from the NIH unit and instructed to eat 25 percent fewer calories than they consumed while on a weight maintenance diet the first 3 days of their inpatient stay. They maintain the lower calorie diet at home for 4 weeks. During this period they come to the NIH unit 3 days a week to receive either real or sham TDCS. ...
