Prevalence and predictors of suicide attempt in an incidence cohort of 661 young people with first-episode psychosis

Studies investigating suicidal behaviour in psychosis rarely focus on incidence cohorts of first-episode patients. This is important, because patients who refuse study participation have higher rates of comorbid substance use disorders and longer duration of untreated psychosis as well as worse course illness, variables potentially linked to higher prevalence of suicidal behaviour. The aims of the present study were therefore to examine the prevalence and predictors of suicide and suicide attempt before and during the first 18-24 months of treatment.

Serious suicidal behaviors: socio-demographic and clinical features in a multinational, multicenter sample

BACKGROUND: Declared suicidal intent and physical danger are both considered important components in defining suicidal behaviors (SB). AIMS: 1) To investigate characteristics of serious suicidal behaviors (SSB), defined by either suicidal intent or lethality; 2) To determine any difference in terms of socio-demographic, clinical and/or service usage variables between SSB and non-serious suicidal behaviors (NSSB). METHODS: A total of 2631 contacts for SB were registered in the context of the MONSUE (Monitoring Suicidal Behavior in Europe) study project. Demographic and clinical information were registered. ICD-10 was used for classifying data about psychiatric diagnoses, methods used for SB and injuries reported. Clear intentionality, high-case fatality methods and serious injuries all defined SSB (n = 1169; 44.4%) RESULTS: SSB were more often preceded by a contact with an inpatient (either psychiatric or somatic) rather than an outpatient service. Among those having a previous history of SB, SSB subjects had fewer contacts with health services before the previous attempt. The strongest predictors for SSB appeared to be older age and not professing a religion. CONCLUSION: Many of the known factors contributing to the risk of completed suicide were also present for SSB. Our findings on service usage by suicide attempters show which aspects of mental health services should be strengthened in order to improve suicide prevention.

Suicidal ideation in a European Huntington's disease population.

BACKGROUND Previous studies indicate increased prevalences of suicidal ideation, suicide attempts, and completed suicide in Huntington's disease (HD) compared with the general population. This study investigates correlates and predictors of suicidal ideation in HD. METHODS The study cohort consisted of 2106 HD mutation carriers, all participating in the REGISTRY study of the European Huntington's Disease Network. Of the 1937 participants without suicidal ideation at baseline, 945 had one or more follow-up measurements. Participants were assessed for suicidal ideation by the behavioural subscale of the Unified Huntington's Disease Rating Scale (UHDRS). Correlates of suicidal ideation were analyzed using logistic regression analysis and predictors were analyzed using Cox regression analysis. RESULTS At baseline, 169 (8.0%) mutation carriers endorsed suicidal ideation. Disease duration (odds ratio [OR]=0.96; 95% confidence interval [CI]: 0.9-1.0), anxiety (OR=2.14; 95%CI: 1.4-3.3), aggression (OR=2.41; 95%CI: 1.5-3.8), a previous suicide attempt (OR=3.95; 95%CI: 2.4-6.6), and a depressed mood (OR=13.71; 95%CI: 6.7-28.0) were independently correlated to suicidal ideation at baseline. The 4-year cumulative incidence of suicidal ideation was 9.9%. Longitudinally, the presence of a depressed mood (hazard ratio [HR]=2.05; 95%CI: 1.1-4.0) and use of benzodiazepines (HR=2.44; 95%CI: 1.2-5.0) at baseline were independent predictors of incident suicidal ideation, whereas a previous suicide attempt was not predictive. LIMITATIONS As suicidal ideation was assessed by only one item, and participants were a selection of all HD mutation carriers, the prevalence of suicidal ideation was likely underestimated. CONCLUSIONS Suicidal ideation in HD frequently occurs. Assessment of suicidal ideation is a priority in mutation carriers with a depressed mood and in those using benzodiazepines.

Radiopaque stomach contents in postmortem CT in suicidal oral medication intoxication: report of three cases

In clinical medicine, plane radiography is used for detecting the remains of medications in the stomach in oral medication intoxication cases. Since postmortem computed tomography (CT), performed prior to autopsy, is currently intensively entering the forensic routine, the technique was applied to three fatal cases of oral medication intoxication. Here we report CT and autopsy findings for these cases. In all three cases, hyperdense areas within the stomach content were documented. The measurement of Hounsfield Units (HU) beyond 74HU showed mean values of 338, 88 and 98HU. Postmortem CT also showed brain edema and pulmonary aspiration in one case. At autopsy, tablet remains in the stomach were detected microscopically in all three cases. The ex vivo CT scans of the ingested medicaments showed similar HU values. Despite the fact that further case studies are necessary beyond this one, and in spite of its limitations, postmortem CT was found to be a useful screening and documentation method for stomach contents in oral medication intoxication.

An fMRI study on mental pain and suicidal behavior

Suicide is a poorly understood phenomenon. A clinical model of suicide conceptualizes suicidal behavior as a solution to an unbearable state of mind, experienced as mental pain.

Suicidal knife wound to the heart: challenges in reconstructing wound channels with post mortem CT and CT-angiography

We present a case of an individual who stabbed himself through the heart with a large knife. Post mortem computed tomography (CT) and CT-angiography were used to assess the stab channel and to reconstruct the sequence of events. After penetrating injuries to the chest, both the intra-thoracic organs and the injury causing instrument may shift (e.g. from pnemothorax) and render forensic reconstructions more challenging. This case report illustrates the potentials and the pitfalls of CT for the reconstruction of penetrating injures to the chest.

Sudden death among young people with first-episode psychosis: An 8-10 year follow-up study

Individuals with first episode psychosis (FEP) experience high rates of premature mortality, in particular due to suicide. The study aims were to: a) Estimate the rate of sudden death among young people with FEP during an 8-10 year period following commencement of treatment; b) Examine and describe the socio-demographic and clinical characteristics associated with sudden death; and c) Examine the timing of death in relation to psychiatric treatment.This was a cohort study. The sample comprised 661 patients accepted into treatment at the Early Psychosis Prevention and Intervention Centre between 1/1/1998 and 31/12/2000. Demographic and clinical data were collected by examination of the medical files. Mortality data were collected via a search of the National Coroners Information System; the Victorian State Coroner's office and clinical files. Nineteen patients died and just over two thirds of deaths were classified as intentional self-harm or suicide. Death was associated with male gender, previous suicide attempt and greater symptom severity at last contact. People with FEP are at increased risk of premature death, in particular suicide. A previous suicide attempt was very common amongst those who died, suggesting that future research could focus upon the development of interventions for young people with FEP who engage in suicidal behaviour.

Predictors of attempted suicide among Swiss patients with alcohol-use disorders

Objective: Suicide attempts are common in patients being treated for alcohol-use disorders (AUDs). However, clinical assessment of suicide risk is difficult. In this Swiss multisite study, we propose a decision tree to facilitate identification of profiles of AUD patients at high risk for suicidal behavior. Method: In this retrospective study, we used a sample of 700 patients (243 female), attending 1 of 12 treatment programs for AUDs in the German-speaking part of Switzerland. Sixty-nine patients who reported a suicide attempt in the 3 months before the index treatment were compared using risk factors with 631 patients without a suicide attempt. Receiver operating characteristic (ROC) analyses were used to identify patients at risk of having had a suicide attempt in the previous 3 months. Results: Consistent with previous empirical findings in AUD patients, a prior history of attempted suicide and severe symptoms of depression and aggression considerably increased the risk of a suicide attempt and, in combination, raised the likelihood of a prior suicide attempt to 52%. In addition, one third of AUD patients who had a history of suicide attempts and previous inpatient psychiatric treatment, or who were male and had previous inpatient psychiatric treatment, also reported a suicide attempt. Conclusions: The empirically supported decision tree helps to identify profiles of suicidal AUD patients in Switzerland and supplements clinicians' judgments in making triage decisions for suicide management.
