Ketamine Alcohol (in Treatment-Resistant Depression)

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 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.

Intimate partner violence (IPV) is a serious public health problem that results in significant health and economic burdens including mortality, morbidity, and poor treatment outcomes. A well-developed field of research suggests that alcohol misuse and posttraumatic stress disorder (PTSD) can lead to IPV. Individuals with PTSD and/or problematic drinking behaviors are at risk for IPV because of several factors that are common symptoms of PTSD. Because individuals with PTSD often drink alcohol to "self-medicate" or cope with distressing PTSD symptoms, PTSD co-occurs with alcohol misuse and alcohol use disorder at extraordinarily high rates. However, few studies have examined the combined effects of alcohol misuse and PTSD on any form of violence. This study will examine the effects of alcohol misuse and posttraumatic stress disorder (PTSD) on alcohol-related intimate partner violence (IPV). We will examine these associations among couples (N=70) in a controlled laboratory setting using validated, standardized methods in a 'real-world' settings using 28 days of ecological momentary assessment (EMA).

Improving alcohol use disorder (AUD) treatment among Veterans is a national public health problem. The rate of AUD among Veterans is twice that of civilians, with up to 50% of Veterans having AUD. Family-based AUD programs are rarely undertaken in busy treatment clinics, and Veterans with problem drinking behavior or AUD are commonly excluded from couple therapies. As a result, there is a need to develop effective family AUD treatments that are both brief and highly accessible to Veterans. The purpose of this study is to evaluate a new treatment add-on called Brief Family-Involved Treatment (B-FIT), which will be delivered via telehealth among Veterans engaged in alcohol-based treatment/therapy. This study is an 12-week, Stage-II, open randomized controlled trial examining B-FIT in combination with treatment as usual (TAU), (in this case B-FIT+ Cognitive Behavioral Therapy treatment) as compared to TAU alone (CBT treatment).Veterans and their treatment companion (family member, partner, friend) will complete weekly assessments during the treatment phase in addition to 3 & 6 month follow-up assessments, all via telehealth.
