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.

This study will establish the relationship between magnitude of opioid exposure and a pupillary measure referred to as PUAL (pupillary unrest in ambient light), in subjects aged 40-60. Previous investigation demonstrated that loss of PUAL was a sensitive, discriminative indicator of opioid toxicity and respiratory depression among subjects aged 20-40 years old. Population data indicate that pupil size and PUAL decline slightly with age. The investigators will explore whether PUAL proves to be a sensitive indicator of opioid exposure and respiratory depression in this older group.

Bipolar I disorder (BP-I) is a common, chronic, and disabling mental illness with significant morbidity and mortality defined by episodes of mania and depression (or symptoms of both at once, known as mixed features). This prospective, observational study will examine effectiveness, functioning and quality of life outcomes in adult patients with BP-I experiencing a major depressive episode (with or without mixed features) requiring treatment and initiating treatment with cariprazine. It will examine outcomes of cariprazine treatment in a real-world setting in patients with BP-I commonly seen in clinical practices. Cariprazine (Vraylar) is a medication indicated in the United States and Canada to treat adult patients experiencing manic, mixed or depressive episodes associated with BP-I. This study plans to enroll approximately 170 adult patients with BP-I from the United States and Canada. Cariprazine should be prescribed by the physician under the usual and customary practice of physician prescription. The decision to initiate treatment with cariprazine should be made prior to, and independently from, the patient's decision to participate in the study. Participants will receive cariprazine as prescribed by their physician. Observational data will be collected during visits which should align to routine standard of care for a duration of up to 24 weeks.

Although most people recover from acute pain (such as pain caused by injury, surgery, repetitive motion, or unknown causes), many people do not fully recover and will experience chronic pain. Untreated posttraumatic stress disorder (PTSD) appears to be a key risk factor for the transition from acute pain to chronic pain. However, few published studies have addressed the issue of preventing the transition from acute to chronic pain via PTSD reduction. This project will aim to test whether trauma-related PTSD symptoms can be reduced using either Stellate Ganglion Block (SGB) treatment or Cognitive Processing Therapy (CPT), and whether reducing PTSD symptoms can prevent the transition from non-injury based acute pain to chronic pain.
