Background: Nicotine dependence leads to about 480,000 deaths every year in the United States. People with major depressive disorder (MDD) are twice as likely to use nicotine compared to the general population. They have greater withdrawal symptoms and are more likely to relapse after quitting compared with smokers without MDD. More research is needed on how nicotine affects brain function in those with MDD. Objective: To understand how nicotine affects symptoms of depression and related brain function. Eligibility: People aged 18 to 60 years, at the time of consent, with and without MDD who do not smoke cigarettes or use other nicotine products. Design: Participants will have 2 or 3 study visits over 1 year. Participants will have 2 MRI scans no less than 4 days apart. Each scan visit will last 5 to 7 hours. At each scan, they will have urine and breath tests to screen for recent use of alcohol, nicotine, and illegal drugs. Before each scan, they will take 1 of 2 medications: nicotine or placebo. Participants will receive each medication once. They will not know which medication they are receiving at each scan. For each MRI scan, they will lie on a table that slides into a cylinder. Sometimes they will be asked to lie still. Sometimes they will complete tasks on a computer. Tasks may include identifying colors or playing games to win money. Each scan will take about 2 hours. Participants will answer questions about their thoughts, feelings, and behaviors before and after each scan. They will have a blood test after each scan.

The goal of the current project is to establish the efficacy and mechanisms of exercise-enhanced fear extinction retrieval and generalization in posttraumatic stress disorder (PTSD). Exposure therapy is the gold standard treatment for PTSD, yet is only associated with remission rates of ~55% and in clear need of improvement. Exposure therapy is hypothesized to work through mechanisms of fear extinction learning, and as such, laboratory-based fear extinction paradigms are widely used as models of exposure therapy. Recent data demonstrates that moderate-intensity aerobic exercise, delivered specifically during or after fear extinction learning, can boost the consolidation of fear extinction learning. Consistent with emerging models of exercise's pro-extinction effect, our pilot data among women with PTSD found that moderate intensity aerobic exercise delivered after fear extinction learning leads to a reduction in subsequent fear responding 24hrs later, an effect that was mediated by exercise-induced increases in peripheral brain derived neurotrophic factor (BDNF). Our pilot data using multivariate pattern analyses (MVPA) also identified divided neurocircuitry organization of fear vs safety memories, and that this divided neural organization was altered in PTSD. Building on our pilot data, the current project would 1) compare the impact of different intensities of exercise delivered following fear extinction learning on multimodal measures of fear extinction retrieval and generalization, 2) identify the impact of exercise on MVPA representations of fear vs safety memories, and 3) demonstrate that spontaneous reactivations of extinction encodings in the acute consolidation window operate as candidate mechanisms by which exercise enhances extinction retrieval and generalization. Using a 3-day fear conditioning, fear extinction, and fear extinction retrieval and recognition task during functional magnetic resonance imaging (fMRI), 200 adults with PTSD would be randomly assigned to either resting control or 30min of either light, moderate, or high intensity exercise. Testing dose-response relationships between exercise intensity and fear extinction will inform translation of this research to clinical settings. A one week-follow-up extinction retrieval test would investigate the impact of exercise on longer-term retention. This project would provide a critical evaluation of the impact of aerobic exercise on consolidation and recall of extinction learning in PTSD samples, thereby providing a strong foundation to translate this research to clinical care and enhance clinical outcomes for PTSD. The project would also provide general knowledge regarding dose-response relationships and neural mechanisms that support enhanced extinction, thereby informing development of additional novel treatments.

Repetitive Transcranial Magnetic stimulation (rTMS) is an FDA-approved therapy for treatment resistant depression (TRD) that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. But studies of rTMS alone show remission rates of ~30%. Additionally, rTMS has not been shown to improve cognitive functioning that may be an independent factor predicting treatment success. This study will develop a novel multimodal treatment, which combines intermittent theta burst stimulation (iTBS) - a type of rTMS with digital mindfulness training to engage brain plasticity, enhance cognition and alleviate depression symptoms in individuals with TRD.

The proposed study aims to establish the feasibility and safety of subcutaneous tocilizumab, a monoclonal antibody (mAb) against interleukin (IL)-6 receptor, in adults with Major Depressive Disorder (MDD) and evidence of peripheral immune activation. IL-6 is a pro-inflammatory cytokine implicated in the pathophysiology of depression. The investigators hypothesize that neutralizing peripheral immune signaling via IL-6 receptor blockade with tocilizumab will improve neural and behavioral measures of reward processing. This is an open-label, proof-of concept, trial in which up to N=20 adults with MDD meeting a specific immune enrichment criterion will receive open-label tocilizumab over 8 weeks. A healthy control (HC) group (N=20) will undergo baseline neuroimaging and blood-based biomarker assessment without receiving the study drug to aid interpretation of findings. Blood-based immune markers and brain MRI scans (including task-based reward activation and resting-state functional connectivity) will be assessed at baseline for all participants and again post treatment for the MDD group.

Sexual and gender minority adults often experience elevated levels of chronic stress due to stigma, discrimination, and social adversity, commonly referred to as minority stress. This persistent stress is associated with increased anxiety, mood disturbances, impaired sleep quality, and reduced quality of life. There is a need for safe, non-pharmacological interventions that can support mental well-being in this population. This randomized, double-blind, placebo-controlled study is designed to evaluate the efficacy and safety of Ashwagandha (Withania somnifera) root extract in reducing stress and improving anxiety and sleep quality in adults experiencing minority stress. A total of 80 adults aged 18 to 45 years who self-identify as sexual or gender minorities and report moderate to high perceived stress will be enrolled. Participants will be randomly assigned to receive either Ashwagandha root extract (300 mg capsules taken twice daily) or an identical placebo for 8 weeks. Efficacy will be assessed using validated psychological and quality-of-life questionnaires, including the Perceived Stress Scale, Depression Anxiety Stress Scale, Pittsburgh Sleep Quality Index, and other mood and minority stress measures. Salivary cortisol will be measured as a biological marker of stress. Safety will be evaluated through monitoring of adverse events throughout the study.

Purpose of the Study Post-traumatic stress disorder (PTSD) is a common and serious condition, but many people cannot get the help they need because there are not enough mental health specialists (like psychologists or psychiatrists) available. This study is testing a new program called NurseNET. The goal of NurseNET is to train nurses to provide a proven, short-term trauma treatment called Narrative Exposure Therapy (NET). Why This Study is Important Most people see their nurse or doctor for health concerns. Because nurses are highly trusted and already work on the front lines of healthcare, they may be in the best position to offer PTSD treatment quickly and conveniently. This study aims to see if nurse-led care can bridge the gap between patients and the treatment they deserve. What the Study Involves Researchers will enroll 100 participants who have symptoms of PTSD. Participants will work with a trained nurse in a primary care setting to complete the NurseNET program. The Treatment: The program consists of 4 to 6 sessions. During these sessions, the nurse helps the patient talk through their life story and process difficult memories in a safe, supportive way. What We Are Measuring: The research team will look at several factors to see if the program is successful: Effectiveness: Do PTSD symptoms improve after working with the nurse? Feasibility and Acceptability: Do patients and nurses find this type of care easy to use and helpful? Health Impact: Since PTSD is linked to heart health, the study will also look at whether the treatment improves things like blood pressure or physical activity levels. Goal of the Research By the end of this study, researchers hope to show that nurses can safely and effectively provide trauma care. If successful, this model could be used across the United States to make PTSD treatment much easier to access for everyone.

This phase II trial tests the safety, side effects and how well group retreat psilocybin therapy works for the treatment of anxiety and depression in patients with solid tumors that have spread from where they first started (primary site) to other places in the body (metastatic) or with hematologic cancers for which no treatment is currently available (incurable). For patients with metastatic, incurable cancer, unrelieved anxiety and existential distress can cause profound suffering. Psilocybin therapy can relieve anxiety and existential distress by disrupting patterns of thinking that contribute to anxiety and depression. Psilocybin is a substance being studied in the treatment of anxiety or depression in patients with cancer. In this study, a pharmaceutical grade of psilocybin will be used that has been approved by the FDA for research, provided by Filament Health. Psilocybin acts on the brain by resetting the brain's activity and increasing connections between brain regions, particularly those involved in mood regulation and self-perception. In this study psilocybin is combined with structured discussions and reflections that enable patients to have new insights about their situation. In a prior study, group retreat psilocybin therapy was proven to be safe and this study tests a refined dosing regimen for symptoms of anxiety and depression in patients with metastatic solid tumors or incurable hematologic malignancies.

The goal of this neuroimaging study is to investigate how emotional states fluctuate in people with bipolar disorder (BD) compared to healthy controls, and to understand the neural mechanisms driving mood instability. The main questions it aims to answer are: - Can emotional states be decoded from fMRI brain activity using machine learning? - Do individuals with BD show more unstable emotional state trajectories (e.g., high metastability, low fractal scaling) than healthy controls? - Does amplifying positive emotions stabilize brain and emotional dynamics in BD? Researchers will compare individuals with bipolar disorder (BD-I or BD-II, currently depressed or mixed state) to healthy controls without psychiatric history to see whether the BD group shows greater fluctuations in emotional brain activity and whether positive emotion regulation strategies normalize this instability. Participants will: - Complete self-report questionnaires on mood, emotion regulation, anxiety, and daily functioning. - Recall and provide short descriptions of personal positive and negative memories to be used in the MRI task. - Undergo fMRI scanning, including: - Resting-state scans - A Think and Regulate Affective States Task (TReAT) where they recall autobiographical memories, rate emotions, and practice amplifying positive mood. - Structural and diffusion MRI for brain mapping. - Receive physiological monitoring (heart rate, respiration) during scanning. - Complete post-scan surveys on emotional state and task experience. This research will help clarify how the brain supports or disrupts emotional regulation in bipolar disorder and may inform the development of personalized, neurobiologically informed treatments for mood instability.

This study teaches participants who are having colorectal surgery how to use mindfulness to feel calmer and manage pain better. Participants will be randomized (like a flip of a coin) into one of two groups: Mindfulness Intervention or Standard Treatment. Those in the Mindfulness group will have a 30-minute Zoom session before surgery to learn simple mindfulness exercises like deep breathing, using senses, and staying focused on the present. On the day after surgery, participants will watch a short video review of the mindfulness exercises. Regardless of the group assigned, participants may be asked to complete questionnaires, and some participants will be asked to complete a semi-structured interview via Zoom, about 2 weeks to 1 month after surgery. Additionally, access to the mindfulness curriculum will be provided to those not randomized to that group. Investigators will collect information such as age, surgery details, pain levels, and pain medication usage. Participants will also fill out surveys before and after surgery to assess physical and mental well-being. All personal information will be kept safe, and interviews or Zoom sessions will be deleted after notes are taken without names attached. Participants will be in this study for about 4 weeks.
