Active clinical trials for "Suicide"

This study evaluates the effects of an accelerated schedule of theta-burst stimulation, termed accelerated intermittent theta-burst stimulation (aiTBS), on the neural networks underlying explicit and implicit suicidal cognition in inpatients with major depressive disorder.

The purpose of this study is to determine if intravenous ketamine reduces suicidal thinking compared to an active placebo (midazolam) in adolescents who have treatment resistant depression and a recent history of a suicide event (defined as a suicide attempt, emergency room evaluation for suicidal thinking, or a transition to inpatient care for suicidality in the past 120 days). The primary objective of this study is to determine whether ketamine reduces suicidal ideation (as measured via the C-SSRS, recent ideation scale) relative to an active control, midazolam, 48-hours after first administration in adolescents with TRD at high suicide risk.

The purpose of this project is to conduct a randomized control trial with 470 Veterans to examine the impact of a revised version of Motivational Interviewing to Address Suicidal Ideation (MI-SI-R) on risk for suicide attempts and suicidal ideation when compared to high quality usual care.

The overall aim of this study is to reduce suicide among sexual and gender diverse youth ages 18-24 years old. This study will compare the effectiveness of two brief suicide prevention interventions that have been adapted for use with this population to use in primary care via telehealth and will recruit youth from primary care clinics in Texas metropolitan areas. The primary study outcome is suicidal ideation. Each clinic will be randomly assigned to deliver one of the two study interventions.

Suicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.

Investigators will evaluate a group format adaptation of Brief Cognitive-Behavioral Therapy for Suicide (i.e., G-BCBT) on suicide ideation (Aim 1), ability to use coping strategies (Aim 2), and overall mental health (exploratory analysis). The combination of tailored means safety counseling and training in evidence-based emotion regulation and cognitive flexibility skills delivered via a 12-session group therapy treatment will decrease service members' overall suicide risk. The group format will provide opportunities to learn and practice skills, thereby enhancing self-efficacy. G-BCBT outcomes are expected to be no worse than Dialectical Behavior Therapy (DBT) group skills training, an existing gold standard intervention that is twice the length of time as G-BCBT.

People with psychotic disorders are excluded from most suicide-focused clinical trials despite incredibly high rates of completed suicide, and interventions that have been tested for this population have shown limited impact on suicide. Emotion dysregulation is a significant suicidogenic factor that is understudied in people with psychotic disorders. The investigators propose to implement and evaluate an intervention targeting emotion dysregulation in people with psychotic disorders while employing rigorous statistical modeling and measurement techniques including Ecological Momentary Assessment, which will support future advanced research on suicide and suicide prevention for this high-risk group.

Suicide cognitions are conceptualized as enduring, chronic vulnerability factors that predispose individuals to suicidal crises. Therefore, modification of these beliefs may reduce suicidal thoughts and behaviors. The goal of this research is to develop, refine, and pilot-test a mobile intervention to reduce cognitions that contribute to elevated suicide risk and to assess the impact of reductions in suicide cognitions and anger cognitions on suicide risk and functioning.

The purpose of this research study is to learn about people who use the National Suicide Prevention (NSP) Lifeline during a suicidal crisis and those who don't. The researchers would also like to learn whether people who have experienced a suicidal crisis could benefit from participating in a therapy session about their thoughts and perceptions of the NSP Lifeline.

The primary goal of this Phase I study is to determine the maximum tolerated dose of oncolytic adenovirus mediated double suicide-gene therapy in combination with fractionated stereotactic radiosurgery in patients with recurrent high-grade astrocytoma undergoing resection.
