Active clinical trials for "Suicide"

The goal of this mixed-methods study is to describe the association between the level of parent/adolescent discordance in the assessment of the adolescent's level of suicidal intentionality after a suicid attempt and the evolution of the suicidal crisis by assessing the evolution of the adolescent's suicidal intentionality between T0 and 3 months. The main questions it aims to answer are: To show the association between the level of parent/adolescent discordance in the assessment of the adolescent's level of suicidal intent after a suicid attempt and various markers of the evolution of the suicidal crisis at 3 months. Explore the experience of adolescents and their parents regarding the elements they consider relevant in assessing the adolescent's suicidal intent. Participants will be asked to complete various self- and hetero-questionnaires at T0 and T3

This study is prospectively enrolling a cohort of adolescent patients who present to the Emergency Department and an inpatient psychiatric adolescent unit with acute suicidality.

The ultimate aim of this study is to identify a biomarker of suicide risk in MDD by measuring the "hedonic spectrum" (pain and reward responsivity), attention and its associated brain structures using brain scans (fMRI and DTI), as well as the stability of markers over time.

Recent studies have revealed an association between history of suicide attempt and inflammatory markers in both the cerebrospinal fluid and the plasma. Post mortem studies have shown an increase in microglial activation in the brain tissue of suicide victims. However the relationship between peripheral and central inflammation in suicide is probably mediated by complex biological processes that are yet elucidated. An increase of blood S100B levels (biomarker of neurovascular damage; PMID 14530574) has been reported in adolescents with suicidal ideation vs. controls and independently of psychiatric disorder. The investigators hypothesize that peripheral inflammation may alter the blood brain barrier, which normally acts as a filter to ensure proper neuronal functioning, in suicidal patients. They propose to investigate peripheral inflammation, neurovascular permeability and miRNAs in suicidal behavior pathophysiology as biomarkers of suicidal behavior in depression

This is a mixed-methods study. The quantitative component will comprise of a multicentre rater-blind, randomized controlled trial to evaluate the feasibility and acceptability of AISHA in addition to treatment as usual (TAU) compared to TAU alone in Pakistan. In-depth interviews and focus groups with other stakeholders will take place to consider the wider implementation of AISHA in mental health services in Pakistan.

Bone marrow or blood stem cell transplantation is used to treat a wide range of life-threatening conditions. T lymphocytes carried in the graft have powerful beneficial effects and play a vital role in the eradication of leukaemia and in fighting infection, but can also damage healthy tissues and cause graft-versus-host disease (GVHD). To safeguard against GVHD, the investigators propose modifying T cells to encode a 'switch' so that they can be eliminated if problems arise. Children receiving half-matched (haploidentical) transplants from a parent are most likely to benefit from this strategy. At present these patients receive blood stem cells from a parent, but the T cells are removed because the risk of serious GVHD is unacceptable. This means that they are much more likely to suffer from life threatening infections or experience a relapse of leukaemia. The investigators want to use gene therapy to produce "safe" T cells which can be used to strengthen the transplant and prevent these serious complications.

The primary purpose of this phase I study is to determine the safety of combining replication-competent adenovirus-mediated suicide gene therapy with chemoradiotherapy in patients with non-metastatic pancreatic cancer.

Safety evaluation of combined immunogene therapy in patients with advanced melanoma.

The researchers seek to develop a text message intervention for caregivers of adolescents at elevated suicide risk following discharge from emergency department (ED) care.

Scientific advances are constantly leading to better treatments. However, it is quite challenging for healthcare systems, including VA, to ask very busy providers to change the way they practice. The MIDAS QUERI program helps providers improve the way they treat VA patients. This project will focus on increasing referrals to the Suicide Prevention 2.0 Clinical Telehealth (SP 2.0) initiative through the delivery of Academic Detailing and LEAP (a team-based quality improvement program). SP 2.0 provides accessible, evidence-based suicide prevention treatment to all Veterans with a history of suicidal self-directed violence or preparatory behaviors in the past 12 months.
