Inhaled DMT for Major Depressive Disorder

This Phase 2b, randomized, double-blind, active-controlled clinical trial will evaluate the efficacy and safety of inhaled N,N-dimethyltryptamine (DMT) in adults with Major Depressive Disorder (MDD). The study will test whether inhaled DMT can rapidly reduce depressive symptoms and suicide risk compared with a low-dose active comparator. A total of 140 participants will be randomized 1:1 to receive either 15 mg followed 1 hour later by 60 mg of inhaled DMT, or 1 mg followed 1 hour later by 4 mg of inhaled DMT. Participants who do not achieve remission at Day 7 will enter an open-label extension and receive a high-dose DMT session on Day 14 (±3 days). All participants will be followed for up to 12 months to evaluate the durability of response, safety, functioning, and quality of life.

Integrating Ketamine Effects on Neuronal Molecular Signatures and the Brain Functional and Structural Connectome

Subanesthetic dose of intravenous ketamine (KET) has been found to be highly effective in rapid treatment depression and associated suicidality but its exact mechanism of remains uncertain. This study will use a novel approach to elucidate KET's effects on the molecular/ gene expression pathways in living neurons obtained from the olfactory epithelium and correlate the changes to rapid improvement in depression via changes in the brain connectome. The study will identify the molecular targets and pathways involved in KET'S mechanism of rapid clinical action and pave the way for development of novel, more efficacious, and safer therapeutic agents.

Self-hangIng Patient and Hyperbaric Oxygen Therapy _ SIPHON Study

During an attempted hanging, patients present severe neurological distress that can lead to major neuropsychiatric sequelae. These sequelae are notably due to significant cerebral edema related to hanging. Hyperbaric Oxygen therapy is known to reduce cerebral edema and improve cerebral perfusion. The main objective of the study is to evaluate in patients who have attempted hanging without presenting cardio-respiratory arrest, the effect of one Hyperbaric Oxygen therapy session in addition to standard intensive care management on a potential reduction in short-term neurological sequelae. Patients will benefit from either standard management or standard management associated with one Hyperbaric Oxygen therapy session

Family Safety Net - Aim 3: Randomized Control Trial

Our parallel group clinical trial of the Family Safety Net (FSN) intervention addresses two main questions: * Is the Family Safety Net (FSN) intervention feasible and acceptable in two formats: motivational interviewing (FSN MI) counseling session and scripted psychoeducational session (FSN Scripted), with a primarily Alaska Native population in Northwest Alaska? * Secondarily, are there signals of efficacy at improving home safety (firearms unloaded, locked with ammunition separate) and dangerous medication locked? All participants will complete a baseline survey with firearm storage questions as well as 3 questions about mental health concerns in their family (e.g. 'Are you worried that someone in your home is at risk of suicide?'). * If participants answer "yes" to any of the following family-focused mental health questions, they will be randomly assigned to one of the two FSN intervention groups (1 and 2 below): 1. In the past two months, has anyone in your household been going through a rough time? 2. In the past two months, has someone in your home seemed down, sad, or depressed? 3. Are you worried that someone in your home is at risk of suicide? * If they do not endorse any of the three family-focused mental health questions, they will be randomly assigned to one of two general firearm safety conditions (3 and 4 below). 1. FSN MI group will participate in a 15-20-minute motivational interviewing (MI) session conducted by trained research staff focused on suicide lethal means reduction. 2. FSN Scripted group will participate in a 10-minute scripted session focused on suicide lethal means reduction. Both FSN groups (1 and 2): * Can take home trigger locks, cable locks, ammo boxes, medication boxes and mental health resources * Receive 4 weeks of tailored text message reminders and encouragement. * Complete 1-month follow-up survey consisting of items related to firearm storage, and facilitating factors hypothesized to contribute to this behavior. * Participants in both FSN conditions will be invited to participate in a semi-structured interview at follow-up focused on satisfaction and perceptions of the program. 3 General gun safety intervention group will participate in a 10-minute scripted conversation about safe gun storage practice, and: * Can take home trigger locks, cable locks, and ammo boxes. * Receive 4 weeks of tailored text message reminders and encouragement. * Complete 1-month follow-up survey consisting of items related to firearm storage, and facilitating factors hypothesized to contribute to this behavior. 4\. General gun safety comparison group: * Can take home trigger locks, cable locks, and ammo boxes. * Complete 1-month follow-up survey.

Reducing Suicide Risk Among Aging Caregivers of Persons With AD/ADRD

This project aims to adapt, implement, and evaluate a Dialectical Behavior Therapy skills training group intervention for aging adult family caregivers of person with Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) to reduce suicidality. By adapting this modality, the investigators will provide a scalable intervention tailored for this high-risk population, maximizing the public health impact and improving suicide prevention.

Study About Group and Phone Follow-Up After a Crisis

Crisis stabilization centers (CSCs) provide a less costly and more comfortable alternative to Emergency Department care for individuals with suicidal crises. With demand for crisis alternatives growing, effective interventions that fit the unique workflows and workforce of CSCs are needed to realize their life-saving potential. To address this need, the investigators will adapt, and pilot test the effectiveness of an interpersonally enhanced recovery and follow-up intervention delivered during and after admissions acute suicidal crises.

RomSi: Mobile Health Intervention to Enhance Suicide Prevention by Reducing Stigma and Increasing Literacy

Suicide is one of the leading causes of death in Spain, representing a public health crisis that requires urgent and effective solutions. The stigma surrounding suicide prevents many at-risk individuals from seeking help, worsening the problem. Addressing this stigma is essential to implement more effective and accessible prevention strategies. This study aims to design and evaluate an innovative mobile health intervention to reduce stigma and encourage help-seeking behaviours in the general population. While the intervention targets the general population, two specific groups will access specialized and tailored content: individuals with low suicidal ideation and family members or close friends of people who have died by suicide. A daily assessment will collect real-time data and evaluate the intervention's impact. The study will employ a randomised controlled trial (RCT) with a crossover design, with participants randomly assigned to immediate or delayed use conditions. The intervention's effectiveness and usability will be assessed at four key points through quantitative analyses and qualitative interviews. We hypothesise that the intervention will improve suicide literacy, reduce suicide-related stigma, increase help-seeking behaviours, and demonstrate high usability and acceptability.

Youth Empowerment and Safety Intervention

This clinical trial will implement and evaluate the feasibility, acceptability, and initial impact of Peer Support Specialist (PSS) services for public system-involved sexual and gender minority (lesbian, gay, bisexual, queer and/or transgender) youth (SGMY) at risk of suicide.

Suicide Prevention for Sexual and Gender Minority Youth (Randomized Controlled Trial)

The overarching goal of this study is to evaluate a newly-developed suicide prevention program for sexual and gender minority youth and emerging adults. After development of the intervention program, a randomized controlled trial will be conducted to test its preliminary efficacy in lowering the risk for suicide attempts.

Rapid Personalization of Safety Plans for Psychiatrically Hospitalized Veterans at High-Risk for Suicide

Veterans psychiatrically hospitalized face significantly elevated suicide risk, particularly in the three months post-discharge. While Safety Planning is a required component of discharge planning, many safety plans lack personalization thereby reducing their effectiveness. The proposed intervention, Personalized Safety Plans (PSP), will be developed for rapid delivery on acute inpatient psychiatry units. PSP is a single-session intervention followed by twice monthly brief, personalized coaching sessions during the three-month high-risk discharge period. PSP will be iteratively refined and finalized in a case series (N = 15) then evaluated in a pilot randomized controlled trial (N = 96) comparing PSP to Safety Plans as Usual among psychiatrically hospitalized Veterans. Overall, the study aims to: 1) iteratively refine PSP; 2) examine PSP's preliminary effectiveness in reducing suicide ideation and increasing adaptive coping; 3) identify barriers and facilitators to implementation; and 4) develop a fidelity measure to support future personalization monitoring.

Brief Problem-solving Intervention in Different Formats for the Prevention of Suicide in Adults Over 50

Suicide represents a personal tragedy and an enormous global public health problem. One of the most vulnerable groups is adults 50 years and older. Despite this stage of life is particularly amenable to the implementation of targeted suicide prevention strategies, we have few studies of the efficacy of psychological interventions, those that do exist have methodological limitations, and none were implemented in formats other than face-to-face, which limits their accessibility. There is a need for brief psychological interventions that can be administered in both face-to-face and remote formats, do not require long training periods, and are effective in different contexts: for example, problem-solving therapy. The main objective of this project is to evaluate the efficacy of a brief problem-solving psychological intervention for targeted suicide prevention in people aged 50 years and older, administered in face-to-face, conference call, and smartphone app formats. A randomized controlled trial will be performed. Participants will be recruited through healthcare centers in the Autonomous Community of Galicia (Spain). To be included, participants must: (a) be at least 50 years old, (b) reside in Galicia, and (c) present suicidal ideation. Subjects will be excluded if they: (a) present serious mental health or medical disorders; (b) have begun receiving psychological or psychopharmacological treatment in the previous two months or are participating in other suicide prevention research; (c) do not have an appropriate mobile device or sufficient fluency to communicate in Spanish, or have problems that make it impossible to participate; or (d) plan to move in the next 18 months. At pre-intervention information will be collected on sociodemographic, family, personal history, current suicide risk and other clinical variables. 212 participants will be randomly assigned to (1) a problem-solving-based psychological intervention delivered face-to-face (PSPI-FF; experimental group 1); (2) a problem-solving-based psychological intervention delivered via telephone conference call (PSPI-CC; experimental group 2); (3) a problem-solving-based psychological intervention delivered via a smartphone app (PSPI-A; experimental group 3); or (4) a usual care control group (UCCG). Participants in the experimental groups will complete the six sessions/modules of the interventions. Finally, subjects in all groups will be evaluated at post-intervention and 3, 6 and 12-month follow-ups.

Preventing Suicidal Behavior With Diverse High-Risk Youth in Acute Care Settings

The study will compare the effectiveness of two relatively brief and scalable evidence-based interventions: the Stanley Brown Safety Planning Intervention and Follow-up Contacts (SPI+), a suicide-specific intervention that helps people prevent suicidal crises from escalating, and Interpersonal Psychotherapy for Adolescents Ultra Short Crisis Intervention (IPT-A SCI), a psychotherapeutic crisis intervention treatment for suicidal adolescents that teaches youth skills to prevent suicidal crises and addresses interpersonal problems that lead to suicidal crises. The results will inform the future standard of care for youth at risk for suicide presenting in the ED setting. This project focuses on suicidal youth ages 12-24 in five ethnically and racially diverse urban areas: Philadelphia, Pennsylvania; Baltimore, Maryland; Chapel Hill, North Carolina; St. Petersburg, Florida; and Northern Manhattan/lower Bronx/eastern Queens communities in New York City, New York.

Youth Depression and Suicide Research Network

The objective of this study is to build the Texas Youth Depression and Suicide Research Network to support the development of a Network Participant Registry and characterization of systems and interventions to examine statewide population health outcomes. All 12-13 sites represented in the Texas Child Mental Health Care Consortium (https://www.utsystem.edu/pophealth/tcmhcc/) have been invited to participate in the Texas Youth Depression and Suicide Research Network as "Nodes." 12 Nodes have been selected for this project. Each Node has obtained support of senior institutional leadership including the department chair. Leadership from each Node provided input and edits in the study design process by committee, with a focus on the inclusion of the "end user" in design decisions. Nodes will work closely with the Network Hub leadership to recruit, monitor, and retain participants. This will require active engagement and sustained relationships with clinics within the academic medical center as well as clinics in the community (i.e., psychiatry, psychology, counselling).

Neural Mechanisms and Predictors of an Ultra-Brief Suicide Prevention Strategy

The current study is a clinical trial, meaning a research study in which human subjects are prospectively assigned to one or more interventions to evaluate the effects of those interventions on health-related behavioral outcomes. Specifically, male and female adults with current suicidal intent will be randomly assigned to receive either a 1-hour session of crisis response planning (CRP) or a 1-hour session of standard crisis risk management (Treatment as Usual). The effects of both conditions on changes in emotion regulation, behavioral inhibition, stress reactivity, and suicide risk will be evaluated post-intervention and at six-month follow-up. Additional assessments of changes in mood and suicidality will be collected daily during the first 10-days following intervention, and then monthly for a duration of six months. A cohort of healthy controls is included in the study but are not randomized to either treatment condition. The investigators hypothesize the following: 1) A single session of CRP will acutely change suicide risk and 2) Individuals who receive CRP will show sustained improvements in measures of suicidality when compared to individuals who received the Treatment as Usual intervention.

Nudging Parental Actions for Youth Suicide Prevention

The goal of the study is to determine effectiveness of a behaviorally informed text messaging intervention to help parents increase safety practices and reduce their teens' access to lethal means following a suicide-related emergency department visit.

Natural History of Depression, Bipolar Disorder and Suicide Risk

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

The BH-Works Suicide Prevention Program for Sexual and Gender Minority Youth

Youth suicide is a serious public health concern. Compared to their heterosexual and cisgender peers, sexual and gender minority (SGM) adolescents report higher rates of suicidal ideation and suicide attempts. Unfortunately, many barriers complicate the implementation of suicide prevention in SGM communities. SGM youth often report feeling unwelcome in traditional behavioral health service organizations. Consequently, treatment attendance and retention remain low. Instead, this population generally seeks mental health services in community organizations for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. These organizations are often unprepared for this clinical challenge. The Behavioral Health-Works (BH-Works) suicide risk management system may offer a potential solution to this problem. BH-Works is an evidence-based, comprehensive youth suicide prevention program. It offers support for policy development, staff training, suicide and behavioral health screening, technology-assisted safety planning, an electronic patient referral system, real-time data analytics for program monitoring, and a learning collaborative structure to support sustainability. All functions are supported on a web-based software platform that facilitates cross-system communication, implementation, adoption, and expansion. In this project, the investigators will adapt this program for LGBTQ organizations and test feasibility, acceptability and preliminary effectiveness. This project builds upon robust partnerships with two diverse LGBTQ organizations in Philadelphia, Pennsylvania and rural Southwest, Virginia) and their respective behavioral health (BH) partnering sites. To facilitate BH-Works adaptation for SGM adolescents, the investigators will employ the Enhancing Engagement trajectory from Lau's cultural adaptation framework. To pilot the program within LGBTQ organizations and their partners, the investigators will use an Effectiveness-Implementation Hybrid Type 2 design with a historical comparison group. Informed by the Consolidated Framework for Implementation Research, the investigators will also pilot test a sequenced implementation strategy. This strategy focuses on promoting engagement, building partnerships, and creating sustainability. In Years 1 and 2, the investigators will collect de-identified treatment as usual data gathered by participating centers, and work with their advisory board and partners to adapt BH-Works policy, content, practices, and workflow. Starting in Year 2, the investigators will train staff/providers in suicide risk management, family engagement and affirmative care. In Years 3 and 4 (no cost extension year), the investigators will test the adapted SGM BH-Works Program and examine several essential program targets (training impact, partnership development, software usability) and outcomes (successful referral, program satisfaction, caregiver involvement, suicide identification).

An Implementation Study of Suicide Risk Management Among Discharged Psychiatric Patients

The post-discharge suicide risk among psychiatric patients is significantly higher than it among patients with other diseases and general population. The brief contact interventions (BCIs) are recommended to decrease the risk in areas with limited mental health service resource like China, however the best frequency to implement BCIs is unknown. This implementation study aims to 1) to develop an intervention strategy against post-discharge suicide based on BCIs for Chinese psychiatric patients; 2) to determine the best frequency of BCIs based on Sequential Multiple Assignment Randomized Trial; 3) to evaluate the effectiveness of the intervention strategy and explore its implementability based on the Implementation Outcome Framework (IOF). Based on the community-based participatory research (CBPR) approach, this study will invite psychiatric patients and family members, psychiatrist and nurses, community mental health workers and social workers as the community team to develop a post-discharge suicide intervention strategy. The study will recruit patients with psychotic symptoms and with major depressive disorder discharged from Shenzhen Kangning Hospital (SKH) in a Sequential Multiple Assignment Randomized Trial (SMART) to determine the best frequency for implementing BCIs and to evaluate the effectiveness. Participants will be randomized into two intervention groups to receive BCIs at different frequencies. Follow-ups to evaluate participants' suicide risk are scheduled at 1, 3, 6 and 12 months after discharge. The re-randomization will be applied at 3 months after discharge. With the Intent-to-treat (ITT) approach, generalized estimating equation (GEE) and survival analysis (SA) will be applied to compare the effectiveness among groups and to explore factors associated with suicide risk. Meanwhile, this study will collect qualitative and quantitative information on implementation and service outcomes from the community team.

TEEM-GIFTS: A Gamified mHealth to Reduce Post-Discharge Suicide Risk

Patients with mental disorders are at significantly higher risk of suicide after discharge compared to the general population and patients with other diseases. Currently, there is a lack of post-discharge community suicide risk management services in China. The research team's preliminary research suggests that mHealth interventions are well-accepted and feasible for reducing the suicide risk in patients with mental disorders. Furthermore, the inclusion of gamification elements can enhance treatment adherence and user engagement. However, determining the appropriate combination of gamification elements and evaluating the implementation effectiveness of gamified mHealth interventions for suicide risk are challenges in transforming these into regular community mental health services. This study will leverage gamification theory and community-based participatory research to design a gamified mHealth intervention model aimed at reducing suicide risk among discharged patients with mental disorders, and to develop a corresponding management strategy. Using the multi-phase optimization strategy (MOST), the study will identify the optimal combination of gamification elements to reduce suicide risk and increase the outpatient follow-up rate. Through an implementation science framework, the investigators will evaluate the process, outcomes, cost, and feasibility of this management strategy with the goal of reducing suicide risk among these patients. The findings from this study will provide a scientific basis for innovative suicide risk management models for discharged patients with mental disorders in China, thereby paving the way for the application of implementation science in mental health.

Investigation on Suicide Risk Factors of Patients With Mood Disorders

This study investigates the level and distribution of suicide risk and learned suicide ability of patients with mood disorders, investigates the related risk factors of suicide and suicide ability formation of patients with mood disorders from multiple dimensions (biological, psychological, social and clinical perspectives) and clarifies their importance, forms a list of suicide risk factors, and establishes a prediction model of learned suicide ability formation. Upon enrollment, participants will undergo comprehensive assessments including blood and urine sample collection and scale evaluation. The collection of scientific blood and urine is mainly used for the exploration of molecular mechanism of disease occurrence and development, the discovery and verification of biomarkers. Scale evaluation includes: Beck Scale for Suicide Ideation , Columbia Suicide Severity Rating Scale,, Hamilton Depression Rating Scale , Hamilton Anxiety Rating Scale, PHQ-9, GAD-7, Personal and Social Function Scale , Schihan Disability Scale , Emotional Adjustment Difficulty Scale , Acquired Capability for Suicide Scale, Interpersonal Needs Questionnaire , Ottawa Self-Injury Scale, Chinese version of Stress Perception Scale and Beck Hopelessness Scale . Follow-up was carried out for 3 months, including whether suicide/self-injury occurred, current status, and some baseline questionnaires (such as BSI-CV, GAD-7, PHQ-9, HAMD-17,HAMA, etc.).

NIMH Clinical Pathway in Rural Appalachian School-based Health Clinics

This study will adapt and evaluate an evidence-based suicide risk screening and follow-up program in two school-based health centers in West Virginia. The suicide screening program is titled the "NIMH Clinical Pathway" and provides tools and procedures for routinely screening adolescents for suicide risk, completing risk assessments, safety planning, lethal means restriction, follow-up referrals, and other disposition planning as appropriate. Investigators aim to do the following: 1. Gather formative data from providers, parents, and youth to inform ways to adapt and implement the NIMH Clinical Pathway so that it can be effectively implemented in rural, Appalachian School-Based Health Centers (SBHCs). 2. Gather preliminary data regarding the feasibility, acceptability, and effectiveness of the adapted intervention.

Drivers of Suicide Mobile App Study

The central purpose of this project is to evaluate and facilitate access to evidence-based best practices for individuals struggling with suicidal ideation and co-occurring behavioral problems, including alcohol misuse, and provide assistance to the patients while they are waiting to receive care, as they are receiving care, and after they return home. While WisePath is highly innovative in how it delivers these best practices, the content is well-established and known to reduce suicidality and alcohol misuse. We will conduct a 12-week intent-to-treat RCT with 120 suicidal adults 22 years and older who may also be experiencing alcohol misuse. Participants will be randomly assigned to WisePath (n=60) or an active control condition (n=60) including a control suicide prevention self-help app plus an electronic wellness resources brochure containing links to health and wellness materials, psychoeducation about suicide, depression, self-help recovery-focused resources (e.g., Alcoholics Anonymous and other 12-Step programs, Moderation Management, etc.), and phone/text information for the 988 Suicide \& Crisis Lifeline. Participants will be assessed at baseline, 4, 8 and 12 weeks.

Sleep and Circadian Interventions for College Students at High Risk of Suicide

The purpose of this study is to examine the extent to which delivering sleep and circadian focused interventions in addition to evidenced based psychiatric care for depression and suicide risk may contribute to decreasing suicide risk among high risk young adults. Investigators will evaluate three interventions targeting sleep in acutely suicidal college students enrolled in intensive outpatient treatment. Participants will be randomly assigned to one of three intervention groups: 1. Triple Chronotherapy (TCT)+ Transdiagnostic Sleep and Circadian Intervention (TSC) 2. Transdiagnostic Sleep and Circadian Intervention (TSC) 3. Sleep Feedback (SF) Participants will be followed for 6 months with primary outcome domains of suicidal thoughts and behaviors and depression evaluated by blinded clinicians at short (Days 1-4 of intervention), medium (2 months) and long (6 month) term intervals.

Investigation of the Antidepressant Effects of (2R,6R)-HNK, an Enhancer of Synaptic Glutamate Release, in Treatment-Resistant Depression

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...
