The purpose of this project is to determine if specific gut microbiome or gut-derived metabolites are associated with depression in patients with Multiple Sclerosis (pwMS). Mechanistically, the investigators further hypothesize that depression in pwMS is related to decreased abundance of gut bacteria with GABA-producing activities and/or with anti-inflammatory properties. To determine if the presence of depression in pwMS is associated with specific gut microbiome, gut-derived metabolites or peripheral blood immune profiles. The investigators will perform a cross-sectional study in clinically stable pwMS recruited at the John L. Trotter MS Center. The investigators will evaluate the presence of depression using the Quality of Life in Neurological Disorders (Neuro-Qol) depression scale, one of the 13 scales in the Neuro-Qol recently developed by the NIH using modern psychometric techniques and validated in pwMS. A total of 120 pwMS will be recruited: 60 with and 60 without depression based on the Neuro-Qol depression scale. At the study visit each participant will be asked to provide a stool sample for microbiome analyses and a blood sample for peripheral blood immunophenotyping. Potential confounders will be collected and treated as covariates in the analyses. These include: 1) degree of disability (EDSS); 2) treatment with anti-depressants and DMTs; 3) a 4-days food diary to evaluate diet composition; 4) weight and height to calculate the BMI; 5) fatigue; 6) level of physical activity; 7) sleep quality.

Objective: Wearable technology holds promising potential for mental health monitoring and detection. Samsung has developed an algorithm that they believe can detect signs of depression and anxiety in smartwatch users. They have used this algorithm to create a "Mindfulness Index," which is an easily understood visual index of mental health. The primary aim of the study is to evaluate the performance of Samsung's Mindfulness Index in identifying those who have received a diagnosis of Major Depressive Disorder (MDD) from a clinician-administered semi-structured diagnostic interview. Research Procedures: The target sample size is 75 individuals diagnosed with current Major Depressive Disorder and 75 healthy controls. To meet this target, the recruitment target is set at 215 participants. Participants will be assigned to the MDD condition, or the healthy control condition based on their score on the Beck Depression Inventory. Each subject will be followed for 3 months. Participants will be provided with a Samsung smartphone and Samsung smartwatch. Participants will be asked to wear the smartwatch 24 hours per day, except while charging. This smartwatch will collect data on heartrate, sleep time, and step count. During the study, each day participants will receive texts prompting a link to a "daily diary." These surveys will ask about depression and anxiety symptoms. Additionally, during the first 3 weeks of the study, participants will participate in ecological momentary assessment; texts will be sent 5 times per day prompting participants to fill out a survey about how they currently feel in that moment. These extra surveys will stop after the first 3 weeks of the study, but the daily diary surveys will continue throughout the study. Furthermore, virtual clinician visits will occur at weeks 4, 8, and 12.

Proposed research will examine time-of-day effects on trauma-related fear extinction using Prolonged Exposure Therapy (PE) telemedicine for Posttraumatic Stress Disorder (PTSD) in the National Center for PTSD (NCPTSD). The primary mechanistic outcome measure will be change in psychophysiological reactivity to script-driven imagery (SDI-PR) measured, in person, at pre-treatment, after 5 PE sessions (mid-treatment), and after all 10 PE sessions (post-treatment). A secondary mechanistic outcome will be session-to-session reduction in peak subjective units of distress (SUDS) ratings to imaginal exposures. The primary clinical outcome will be change in Clinican Administered PTSD Scale (CAPS-5) severity score; a secondary clinical outcome will be session-to-session reduction in self-reported PTSD symptoms using the PTSD checklist (PCL-5). Participants meeting inclusion criteria (described below) will be randomized to either PE sessions that begin from 07:00 to a time no later than 2 hours past a participant's customary rise time, or to the last treatment session of the day beginning at 16:00 or later (26 per arm). Participants will complete daily at-home imaginal-exposure homework within the same time frame as their PE sessions are scheduled, i.e., within 2 hours of awakening for morning (AM) group and between 16:00 and 2 hours before bedtime for late afternoon (PM) group.

Mounting evidence shows that the gut microbiome plays an important role in communication within the gut-brain axis. However, the relationship between gut microbiota and their influence on anxiety is still not fully understood. Recent studies on mice found a specific microbe-produced molecule, 4-ethylphenyl sulfate (4EPS), can induce anxious behavior. 4EPS is produced by gut microbes in mice and humans. Research suggests higher 4EPS levels may strongly be associated with anxiety levels. However, anxiety is far more complicated than changes in a single molecule. There are many more factors to consider when it comes to anxiety, including various aspects of one's lifestyle and how humans perceive their environment (cognitive orientation). The primary research goal is to better understand the effects 4EPS has on human anxiety behavior and the role cognitive orientation has in connection to anxiety.

The diagnosis of major depression relies on patient reports, and two patients with the same diagnosis might share only one symptom. Thus, a single mechanism is unlikely to underlie a broad descriptive diagnosis such as major depression. Our approach is anchored by a neural circuit taxonomy that proposes distinct biotypes of depression derived from functional magnetic resonance imaging (fMRI) (Williams et al., 2016). In this study, we aim to target a putative type of major depression that arises from dysfunction in cognitive control neural circuitry with a drug called guanfacine.

The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serotonergic psychedelics through any clinical trial at Yale University. The main questions it aims to answer are: 1. Do serotonergic psychedelics cause the brain to rely on new information more than previously learned information while under the influence? What about 1 day, 5-14 days, and 4-6 weeks after use? 2. Do serotonergic psychedelics cause long-lasting side-effects in how people perceive (see, hear, feel, etc.) the world and how easily people change their beliefs? 3. How does the brain's electrical activity change after using serotonergic psychedelics? How does the balance between excitation and inhibition change while under their effect? 4. Can changes in how the brain uses information predict who will benefit from a psychedelic and who will have side effects from psychedelics? Researchers will compare with people given placebos to see what changes in brain processing are unique to serotonergic psychedelics. Participants will have the opportunity to do some combination of the following: 1. Online computer assessments consisting of games and questionnaires that probe how participants think. 2. Magnetoencephalography (MEG) or electroencephalography (EEG) with eyes closed and with repeated clicks, images, or sensations delivered. 3. A magnetic resonance imaging (MRI) scan. 4. Semi-structured qualitative interviews about their experience after taking a serotonergic psychedelic recorded via Zoom.

Chronic pain (CP) is a major health problem for military Veterans, and CP is often associated with comorbid mental health problems, including posttraumatic stress disorder (PTSD) and depression. CP with psychological comorbidity is associated with increased healthcare costs, medication use, risk of suicide and rates of disability and reduced quality of life. Current empirically supported treatments do not always lead to substantial improvements (up to 50% of patients drop out or are do not respond to treatment). This project was designed to evaluate the efficacy of a novel intervention for addressing these challenges. Compassion meditation (CM), a meditative practice that focuses on the wish to remove suffering, is a contemplative practice that has promise for the amelioration of physical and mental health problems as well as promoting positive affect and improving quality of life. This study will evaluate the efficacy of Cognitively-Based Compassion Training for Chronic Pain with Psychological Comorbidity (CBCT-CP+) compared to Health Education while Living with Pain (H.E.L.P.) control condition, in a sample of among Veterans with CP conditions and psychological comorbidity.

This research study is designed to test if electrical stimulation of the surface of the brain in the frontal region will help treat depressive symptoms. Participants receive intermittent electrical stimulation to the brain, which involves surgically placing electric leads in between the tough fibrous membrane covering the surface of the brain and the surface of the brain itself. This type of stimulation is referred to as bilateral subdural prefrontal cortical stimulation (PCS) because it will specifically target the outer layer of the brain at the midline, right behind the forehead. It uses a pacemaker-like device, the Proclaim Elite SCS System (non-rechargeable) or the Eterna SCS System (rechargeable), both by Abbott Laboratories for stimulation. Although the U.S. Food and Drug Administration (FDA) has approved the Proclaim Elite SCS system for brain stimulation for patients with chronic pain and muscular diseases, such as Parkinson's, its use is still investigational, and the surgery is still experimental for patients who have depression.
