Risk Factors for Reattempt and Suicide Within 6 Months After an Attempt in the French ALGOS Cohort: A Survival Tree Analysis

OBJECTIVE

Understanding the cumulative effect of several risk factors involved in suicidal behavior is crucial for the development of effective prevention plans. The objective of this study is to provide clinicians with a simple predictive model of the risk of suicide attempts and suicide within 6 months after suicide attempt.

METHODS

A prospective observational cohort of 972 subjects, included from January 26, 2010, to February 28, 2013, was used to perform a survival tree analysis with all sociodemographic and clinical variables available at inclusion. The results of the decision tree were then used to define a simple predictive algorithm for clinicians.

RESULTS

The results of survival tree analysis highlighted 3 subgroups of patients with an increased risk of suicide attempt or death by suicide within 6 months after suicide attempt: patients with alcohol use disorder and a previous suicide attempt with acute alcohol use (risk ratio [RR] = 2.92; 95% CI, 2.08 to 4.10), patients with anxiety disorders (RR = 0.98; 95% CI, 0.69 to 1.39), and patients with a history of more than 2 suicide attempts in the past 3 years (RR = 2.11; 95% CI, 1.25 to 3.54). The good prognosis group comprised all other patients.

CONCLUSIONS

By using a data-driven method, this study identified 4 clinical factors interacting together to reduce or increase the risk of recidivism. These combinations of risk factors allow for a better evaluation of a subject's suicide risk in clinical practice.

Development of an Online Resource for People Bereaved by Suicide: A Mixed-Method User-Centered Study Protocol

Introduction: Suicide bereavement is known to be highly distressing and is frequently associated with mental health problems. Despite high-level of need regarding mental and physical health, people bereaved by suicide display low level of help-seeking and perceived support in the aftermath of the loss. The lack of accessibility and reliability of face-to-face counseling resources is notably reported by suicide survivors. Online resources can enhance early access to help and support for people bereaved by suicide. The primary objective of the study is to design and implement an innovative and adaptive online resource for people bereaved by suicide according to their needs and expectation regarding online solutions dedicated to suicide bereavement. Methods: The ESPOIR₂S study is a mixed-method user-centered study. ESPOIR₂S seeks to build the resource from the perspectives and needs of both people bereaved by suicide and professionals or volunteers working in the field of postvention. The Information System Research (ISR) Framework is used to guide the design of the study through a 3-step research cycle. The structure of the ESPOIR₂S study relies on a simultaneous collection of qualitative and quantitative data which will be collected and analyzed during (a) the Relevance cycle through an online questionnaire and focus groups; (b) the Design cycle through focus groups; and (c) and the Rigor cycle through an online questionnaire and semi-structured interviews. The user-centeredness will be ensured by the active participation of people bereaved by suicide, members of associations for bereaved people and professionals of postvention. Discussion: The mixed-method and user-centered design of the ESPOIR₂S study will offer an in-depth collection of the needs and expectation of suicide survivors regarding online resources. Through the implementation of an adaptive online solution, we aim to enhance the access to help and support for suicide survivors which are highly correlated with well-being and recovery.

Occurrence of Side Effects in Treatment-Resistant Depression: Role of Clinical, Socio-Demographic and Environmental Characteristics

Introduction: Treatment-resistant depression (TRD) is a disabling psychiatric condition characterized by the failure of two antidepressants (ADs). Since the occurrence of side effects (SEs) appears to be one of the main determinants of early discontinuation of pharmacological treatments contributing to a pseudo-resistance, the purpose of this study was to determine the parameters associated with the occurrence of SEs under ADs in a cohort of patients with TRD. Methods: An observational, cross-sectional, multicentre study was carried out using data from the French network of Expert Centers for TRD. For the 108 patients enrolled in the study, the statistical analyses focused on the overall occurrence and on the profile of the SEs (9 categories, 32 items). Results: SEs were influenced by age and sex and were positively associated with the intensity of anxious, depressive and suicidal symptoms, a history of childhood trauma (sexual abuse, emotional abuse and neglect), and negatively associated with self-esteem, and assessment of overall functioning. Conclusion: Using variables accessible in common practice, these results fall within the dynamic of a more tailored approach to medicine that could allow, through integrated pharmacological management, the continuation of antidepressant treatments, and therefore limit the risk of therapeutic failure.

Association between anhedonia and suicidal events in patients with mood disorders: A 3-year prospective study

BACKGROUND

As almost all mental disorders are associated with increased suicidal-related behavior, anhedonia might be a trans-diagnostic dimension to target for suicide prevention.

METHODS

For this 3-year-long prospective study, 2,839 outpatients with mood disorders were recruited. They were divided in: (a) two groups according to the occurrence or not of suicidal ideation during the follow-up, and (b) two groups according to the occurrence or not of suicide attempts during the follow-up. Anhedonia was assessed using a composite score (the French version of the 14-item Snaith-Hamilton Pleasure Scale and item 13 of the Quick Inventory of Depressive Symptomatology scale) at inclusion and at 6, 12, 24, and 36 months after inclusion.

RESULTS

Patients with mood disorders and anhedonia at least at one follow-up visit had a 1.4-fold higher risk of suicidal ideation (adjusted odds ratio = 1.35; 95% confidence interval [1.07, 1.70]), even after adjustment for confounding factors of suicide risk (i.e., bipolar or unipolar disorder, sex, age, marital status, education level, antidepressant intake, personal history of suicide attempt, at least one childhood trauma, and mean of the maximum depression score during the follow-up). Conversely, association between anhedonia and suicide attempt did not remain significant after adjustment.

CONCLUSIONS

The significant association between anhedonia and suicide ideation in patients with mood disorders stresses the need of targeting hedonia in mood disorders, and of research focusing on the position to pleasure in life through eudaimonia.

Is COVID-19 Associated With Posttraumatic Stress Disorder?

OBJECTIVE

To assess the prevalence of and risk factors for posttraumatic stress disorder (PTSD) in patients with COVID-19.

METHODS

We conducted a cohort study between March and May 2020 at the Lille University Hospital (France), including all patients with laboratory-confirmed COVID-19. Psychological distress symptoms were measured 3 weeks after onset of COVID-19 symptoms using the Impact of Event Scale-6 items (IES-6). The evaluation of PTSD symptoms using the PTSD Checklist for DSM-5 (PCL-5) took place 1 month later. Bivariate analyses were performed to analyze the relationship between PCL-5 scores and the demographic and health variables. The significant variables were then introduced into a multivariable linear regression analysis to establish their relative contributions to the severity of PTSD symptoms.

RESULTS

180 patients were included in this study, and 138 patients completed the 2 evaluations. Among the 180 patients, 70.4% patients required hospitalization, and 30.7% were admitted to the intensive care unit. The prevalence of PTSD was 6.5%, and the predictive factors of PTSD included psychological distress at the onset of the illness and a stay in an intensive care unit.

CONCLUSIONS

The prevalence of PTSD in patients with COVID-19 is not as high as that reported among patients during previous epidemics. Initial psychological responses were predictive of a PTSD diagnosis, even though most patients showing acute psychological distress (33.5% of the sample) improved in the following weeks. PTSD symptoms also increased following a stay in an intensive care unit. Future studies should assess the long-term consequences of COVID-19 on patients' mental health.

Emotional response in depersonalization: A systematic review of electrodermal activity studies

BACKGROUND

Depersonalization is a complex phenomenological experience initially described as a psychological disturbance of self-awareness. Among the different dimensions underlying depersonalization, emotional numbing appears to be a key symptom but remains a poorly understood phenomenon.

METHOD

We conducted a systematic review, following PRISMA guidelines, of studies investigating electrodermal activity, a well-documented marker of bodily arousal expression of emotion. Studies were selected from the PubMed, Scopus, Web of Science and PsychINFO databases.

RESULTS

Among the 64 studies initially identified, 11 were finally included, involving 148 patients with depersonalization disorder and 173 healthy subjects for whom depersonalization symptoms were assessed. The main results of these studies suggest that depersonalization is marked by a high skin conductance level and attenuated skin conductance responses to negative stimuli.

LIMITATIONS

Due to discrepancies in methodology, we were not able to conduct quantitative analyses. Moreover, the studies included had limited sample sizes, restricting the generalizability of the results.

CONCLUSION

Though further evidence is required, it appears from electrodermal studies that depersonalization is associated with hypervigilance and emotional detachment during threatening situations. However, because emotional numbing might not be restricted to negative events, we proposed perspectives for future research, stressing the need to explore emotional responses of patients with depersonalization to positive situations.

The Role of Adolescence in Development Paths Toward Suicide: Specificities and Shaping of Adversity Trajectories

Purpose: Adolescence is a key period of transitions in the psychological, cognitive, neurobiological and relational domains, which is associated to high susceptibility to adverse life experiences. However, the way adolescent development alters life paths toward suicide remains unclear. Thereby, we aimed at testing whether and how adolescence interfered with the adversity trajectories of individuals who died by suicide. Methods: In a sample of 303 individuals who died by suicide, longitudinal Burden of Adversity ratings were derived from extensive psychological autopsies and life trajectory narrative interviews conducted with informants. Piecewise Joint Latent Class Models allowed the identification of patterns of adversity trajectories and tested the introduction of breakpoints in life-paths. Classes inferred from the optimal model were compared in terms of socio-demographics, psychopathology, and rate of different adverse life events. Results: The most accurate model derived 2 trajectory patterns with a breakpoint in early adolescence. In the first class (n = 39), the burden of adversity increased steadily from birth to death, which occurred at 23 (SE = 1.29). In the second class (n = 264), where individuals died at 43 years of age (SE = 0.96), the burden of adversity followed a similar trajectory during infancy but stabilized between 10 and 14 years and started to increase again at about 25. Childhood family instability, dependent events, exposure to suicide, intra-family sexual victimization and affective disorders at death were more frequent in class 1. Conclusions: A bifurcation in trajectories between early and late suicides occurs during adolescence. The dynamic pattern of adversity during this period is a key issue to understand the developmental heterogeneity in suicide risk.

A Digital Companion, the Emma App, for Ecological Momentary Assessment and Prevention of Suicide: Quantitative Case Series Study

BACKGROUND

Many suicide risk factors have been identified, but traditional clinical methods do not allow for the accurate prediction of suicide behaviors. To face this challenge, emma, an app for ecological momentary assessment (EMA), ecological momentary intervention (EMI), and prediction of suicide risk in high-risk patients, was developed.

OBJECTIVE

The aim of this case report study was to describe how subjects at high risk of suicide use the emma app in real-world conditions.

METHODS

The Ecological Mental Momentary Assessment (EMMA) study is an ongoing, longitudinal, interventional, multicenter trial in which patients at high risk for suicide are recruited to test emma, an app designed to be used as a self-help tool for suicidal crisis management. Participants undergo clinical assessment at months 0, 1, 3, and 6 after inclusion, mainly to assess and characterize the presence of mental disorders and suicidal thoughts and behaviors. Patient recruitment is still ongoing. Some data from the first 14 participants who already completed the 6-month follow-up were selected for this case report study, which evaluated the following: (1) data collected by emma (ie, responses to EMAs), (2) metadata on emma use, (3) clinical data, and (4) qualitative assessment of the participants' experiences.

RESULTS

EMA completion rates were extremely heterogeneous with a sharp decrease over time. The completion rates of the weekly EMAs (25%-87%) were higher than those of the daily EMAs (0%-53%). Most patients (10/14, 71%) answered the EMA questionnaires spontaneously. Similarly, the use of the Safety Plan Modules was very heterogeneous (2-75 times). Specifically, 11 patients out of 14 (79%) used the Call Module (1-29 times), which was designed by our team to help them get in touch with health care professionals and/or relatives during a crisis. The diversity of patient profiles and use of the EMA and EMI modules proposed by emma were highlighted by three case reports.

CONCLUSIONS

These preliminary results indicate that patients have different clinical and digital profiles and needs that require a highly scalable, interactive, and customizable app. They also suggest that it is possible and acceptable to collect longitudinal, fine-grained, contextualized data (ie, EMA) and to offer personalized intervention (ie, EMI) in real time to people at high risk of suicide. To become a complementary tool for suicide prevention, emma should be integrated into existing emergency procedures.

Factors Associated With Mental Health Disorders Among University Students in France Confined During the COVID-19 Pandemic

IMPORTANCE

The coronavirus disease 2019 (COVID-19) pandemic and quarantine measures have raised concerns regarding their psychological effects on populations. Among the general population, university students appear to be particularly susceptible to experiencing mental health problems.

OBJECTIVES

To measure the prevalence of self-reported mental health symptoms, to identify associated factors, and to assess care seeking among university students who experienced the COVID-19 quarantine in France.

DESIGN, SETTING, AND PARTICIPANTS

This survey study collected data from April 17 to May 4, 2020, from 69 054 students living in France during the COVID-19 quarantine. All French universities were asked to send an email to their students asking them to complete an online questionnaire. The targeted population was approximately 1 600 000 students.

EXPOSURE

Living in France during the COVID-19 quarantine.

MAIN OUTCOMES AND MEASURES

The rates of self-reported suicidal thoughts, severe distress, stress, anxiety, and depression were assessed using the 22-item Impact of Events Scale-Revised, the 10-item Perceived Stress Scale, the 20-item State-Trait Anxiety Inventory (State subscale), and the 13-item Beck Depression Inventory, respectively. Covariates were sociodemographic characteristics, precariousness indicators (ie, loss of income or poor quality housing), health-related data, information on the social environment, and media consumption. Data pertaining to care seeking were also collected. Multivariable logistic regression analyses were performed to identify risk factors.

RESULTS

A total of 69 054 students completed the survey (response rate, 4.3%). The median (interquartile range) age was 20 (18-22) years. The sample was mainly composed of women (50 251 [72.8%]) and first-year students (32 424 [47.0%]). The prevalence of suicidal thoughts, severe distress, high level of perceived stress, severe depression, and high level of anxiety were 11.4% (7891 students), 22.4% (15 463 students), 24.7% (17 093 students), 16.1% (11 133 students), and 27.5% (18 970 students), respectively, with 29 564 students (42.8%) reporting at least 1 outcome, among whom 3675 (12.4%) reported seeing a health professional. Among risk factors identified, reporting at least 1 mental health outcome was associated with female gender (odds ratio [OR], 2.10; 95% CI, 2.02-2.19; P < .001) or nonbinary gender (OR, 3.57; 95% CI, 2.99-4.27; P < .001), precariousness (loss of income: OR, 1.28; 95% CI, 1.22-1.33; P < .001; low-quality housing: OR, 2.30; 95% CI, 2.06-2.57; P < .001), history of psychiatric follow-up (OR, 3.28; 95% CI, 3.09-3.48; P < .001), symptoms compatible with COVID-19 (OR, 1.55; 95% CI, 1.49-1.61; P < .001), social isolation (weak sense of integration: OR, 3.63; 95% CI, 3.35-3.92; P < .001; low quality of social relations: OR, 2.62; 95% CI, 2.49-2.75; P < .001), and low quality of the information received (OR, 1.56; 95% CI, 1.49-1.64; P < .001).

CONCLUSIONS AND RELEVANCE

The results of this survey study suggest a high prevalence of mental health issues among students who experienced quarantine, underlining the need to reinforce prevention, surveillance, and access to care.

Supportive effect of body contact care with ylang ylang aromatherapy and mobile intervention team for suicide prevention: A pilot study

OBJECTIVES

To assess understudied, alternative suicide prevention modalities in a mental health care setting.

METHODS

This was a prospective study of patients (n = 140, 68 cases and 72 controls) who were admitted to hospital or who contacted an SOS suicide crisis line for suicidal ideation or attempts. Psychiatric diagnoses (Mini-International Neuropsychiatric Interview) and intensity of anxiety/depression/suicidality (Hamilton Anxiety Rating Scale, Montgomery-Åsberg Depression Rating Scale, and Beck Scale for Suicidal Ideation) were assessed. All intervention group subjects received a crisis card with a crisis line number, interviews with psychologists or volunteers and a telephone call on days 10 to 21, then 6 months later. These subjects also had a choice between two further 4-month interventions: body contact care or mobile intervention team visits.

RESULTS

The interventions significantly reduced the number of suicide attempts and suicide (3%) at 6 months compared with the control condition (12%). There were fewer losses to follow-up in the intervention group (7.35%) than in the control group (9.72%).

CONCLUSIONS

The results favour the implementation of integrated care and maintaining contact in suicide prevention.

Depression with and without a history of psychotic symptoms in the general population: sociodemographic and clinical characteristics

BACKGROUND

The aim of this study was to find the sociodemographic and clinical characteristics of major depressive episode (MDE) with (MDE-HPS+) and without a history of psychotic symptoms (MDE-HPS) in the general population.

METHODS

The Mental Health in the General Population survey interviewed 38,694 individuals in France by using the MINI. The prevalence and sociodemographic and clinical correlates of MDE-HPS+ were assessed.

RESULTS

Of the sample, 11.2% were diagnosed with current MDE and among them, 39.3% presented a history of at least one psychotic symptom (hallucination or delusion). Patients with MDE-HPS+ were younger with more severe social impairment than those with MDE-HPS-. We also found a higher proportion of three generations of migrants in the MDE-HPS+ group. Comorbid psychiatric disorders such as a history of a manic episode, alcohol use disorder, social anxiety, generalized anxiety disorder, and a personal history of a suicide attempt were more frequent in patients with MDE-HPS+ than in those with MDE-HPS-. Finally, we found a specific gradient of severity for psychiatric comorbid disorders depending on the number of psychotic symptoms lifetime in MDE.

LIMITATIONS

The study also has an observational cross-sectional design that does not permit causal inferences, and it is difficult to eliminate recall bias and reporting errors.

CONCLUSION

In the general population, patients with MDE-HPS+, when compared to MDE-HPS-, presented with a more severe clinical profile, with increased rates of psychiatric comorbidities, particularly a history of bipolar disorder and a history of a suicide attempt.

The PRINTEMPS study: protocol of a cluster-randomized controlled trial of the local promotion of a smartphone application and associated website for the prevention of suicidal behaviors in the adult general population in France

BACKGROUND

Suicide constitutes a cause of death which could be prevented by e-health programs accessible to the general population. Effective promotion has the potential to maximize the uptake of such programs. However, few e-health programs have been combined with promotion campaigns. The primary objective of this trial is to assess the effectiveness of a tailored promotion, at a local level, of a mobile application and website offering evidence-based content for suicide prevention (the StopBlues program), and to compare the effectiveness of two types of local promotion in terms of their impact on suicidal acts. Secondary objectives focus on the effectiveness of the promotion in terms of the intensity of utilization of the StopBlues program, help-seeking behaviors and the level of psychological impairment of program users.

METHODS/DESIGN

This is a three-arm, parallel-group, cluster-randomized controlled trial, with before-and-after observation. Thirty-four clusters, corresponding to geographical areas sharing a common local authority in France, will be included. They will be randomly assigned to one of the following arms with a ratio of 1:1:1: a control group; a basic promotion group in which promotion of the StopBlues program will be done by local authorities; and an intensified promotion group in which basic promotion will be supplemented by an additional one in a general practitioner's waiting room. The primary outcome measure will be the number of suicidal acts within each cluster over a 12-month period following the launch of the intervention. Baseline data will be collected for each cluster over the 12-month period prior to the trial. Secondary outcomes will include length of use of the StopBlues program, measures of help-seeking behaviors and level of psychological distress among users of the program, as well as the cost-effectiveness and budgetary impact of its promotion. A more sustained promotion by local authorities will also be implemented after 12 months in the control group and assessed using the same outcome measures.

DISCUSSION

This research should contribute to the sparse evidence base regarding the promotion of e-health programs and will support the wider delivery of the intervention evaluated if proven effective.

[Psychopathological consequences of confinement]

The psychological effects of isolation have already been described in the literature (polar expeditions, submarines, prison). Nevertheless, the scale of confinement implemented during the COVID-19 pandemic is unprecedented. In addition to reviewing the published studies, we need to anticipate the psychological problems that could arise during or at a distance from confinement. We have gone beyond the COVID-19 literature in order to examine the implications of the known consequences of confinement, like boredom, social isolation, stress, or sleep deprivation. Anxiety, post-traumatic stress disorder, depression, suicidal or addictive behaviours, domestic violence are described effects of confinement, but the mechanisms of emergence of these disorders and their interrelationships remain to be studied. For example, what are the mechanisms of emergence of post-traumatic stress disorders in the context of confinement? We also remind the reader of points of vigilance to be kept in mind with regard to eating disorders and hallucinations. Hallucinations are curiously ignored in the literature on confinement, whereas a vast literature links social isolation and hallucinations. Due to the broad psychopathological consequences, we have to look for these various symptoms to manage them. We quickly summarize the diagnostic and therapeutic approaches already in place, such as telemedicine, which is undergoing rapid development during the COVID-19 crisis.

A blended cognitive behavioral intervention for patients with adjustment disorder with anxiety: A randomized controlled trial

Adjustment disorder with anxiety (ADA) is a common psychiatric pathology worldwide, but it is often undertreated. Cognitive behavioral therapy (CBT) is the first-line treatment, but very few studies have been carried out for the treatment of ADA. Internet-delivered CBT (iCBT) appears to be an effective treatment option, with the potential to reach a larger proportion of individuals suffering from ADA. Guidance is a beneficial feature of iCBT, provided in most studies by email or telephone (traditional guided iCBT). Blended CBT, which combines an online intervention and therapeutic guidance provided in person (face-to-face), could be a way to benefit from both the advantages of face-to-face CBT regarding human interactional quality and the advantages of internet-based CBT in terms of improved access to treatment. In this randomized controlled trial, the effectiveness of two forms of administration of Seren@ctif, a 5-week CBT program for patients with ADA according the DSM-5, was examined: one delivered through face-to-face sessions (face-to-face CBT) and the other delivered online and guided with face-to-face contact with a nurse (blended CBT); these formats were compared with a wait-list control group (WLC). A total of 120 patients were included and randomized to one of these three conditions. Measures were administered before treatment, after treatment and 6 months after inclusion in the study. Both treatment conditions displayed significant decreases in anxiety, depression, worry and perceived stress at posttreatment when compared to the WLC group. The decrease in symptoms was mostly maintained 6 months after inclusion for the two experimental groups. Blended CBT showed significantly greater reductions in anxiety and depression than did face-to-face CBT on some secondary outcome measures. We conclude that both face-to-face CBT and blended CBT are effective treatments for patients with ADA, and we suggest that blended CBT may be slightly more effective than classical face-to-face CBT.

[Evolution of electro-convulsive therapy activity in France since the beginning of the COVID-19 pandemic]

La pandémie récente de COVID-19 a entraîné des changements organisationnels majeurs dans les lieux de soins et notamment en hospitalisation en psychiatrie. Pour évaluer l’évolution de l’activité des différents centres pratiquant l’ECT, une enquête nationale en ligne a été réalisée. 65 réponses de toute la France ont été analysées. Plus de 90 % des centres pratiquant l’ECT ont connu une diminution de leur activité. Plus inquiétant encore, la moitié des centres ont subi un arrêt total de leur activité et un quart des centres accusent une diminution de plus de la moitié de leur activité habituelle. Les soins psychiatriques post-pandémie COVID-19 s’annoncent difficiles. Il est essentiel de ne pas ajouter à cette difficulté les complications, souvent graves, qui seront liées au retard ou à l’arrêt de la pratique de l’ECT. Il conviendra aussi de rester vigilant quant aux conséquences spécifiques neuropsychiatriques qui feront suite à la pandémie.

Are there specific care requirements for patients with schizophrenia and diabetes or with a risk of diabetes?

An interactive workshop was held to discuss the risk of diabetes in patients with schizophrenia, to evaluate the available data concerninghow such patients should be managed in terms of minimising the risk of diabetes and of optimising their care where diabetes to develop. The subjects discussed covered monitoring of risk factors, education about lifestyle and the risk of diabetes, patient care and treatment options, and interfaces between psychiatry and diabetology. The workshop noted that all patients with a diagnosis of schizophrenia had an elevated risk of developing diabetes and that this needed to be reflected in the follow-up of the patients in order to reduce the chances of the emergence of disease. The risk of diabetes is complicated by the presence of other risk factors and the intensity of the diabetes prevention programme needs to reflect adequately the overall risk. The most important prevention methods relate to lifestyle changes that patients with schizophrenia may be spontaneously unlikely to adopt and therefore necessitate the implementation of specific education measures aimed at patients and their families. The workshop proposed follow-up intensities, monitoring procedures and prevention programmes stratified according to the risk of developing diabetes. It was not considered that there was sufficient data available to orientate treatment choices between individual antipsychotic drugs according to the potential risk of developing diabetes.

Data on diabetes from the French cohort study in schizophrenia

To establish the impact of antipsychotic medication on the incidence of diabetes, we have analysed data from the prospective French Cohort study of mortality in schizophrenia. This generated a large database of 3470 patients with schizophrenia initially enrolled in 1993 for which data collection on comorbidity has been collected systematically every three years since. The primary objective of the study was to evaluate the mortality rate in the study cohort. From this database, the prevalence and incidence of diabetes can be studied. In 1993, nine patients in 10 were prescribed conventional antipsychotics and the remainder amisulpride and clozapine. Since the introduction of risperidone and olanzapine, atypical antipsychotics are now used in one-third of patients. Multiple antipsychotic medications are used in many patients, with the exception of those receiving clozapine. At inclusion, 2.2% of patients in the study cohort had a diagnosis of diabetes. Morbidity rates were higher in females than in males (3.4% and 1.6%, respectively) and it was only in females that the standard morbidity ratio with respect to the general population was significantly elevated (2.2; 95% confidence intervals: 1.6 and 2.9). The prevalence of diabetes in the study cohort rose over the course of the study. Multivariate regression analysis was performed in order to identify potential determinants of diabetes. For pre-existing diabetes, four factors were identified: age at first hospitalisation, age, obesity and duration of schizophrenia. The same factors with the exception of length of illness were identified for the incident cases. There was no evidence for an interaction between the class and type of antipsychotic medication and risk of treatment emergent diabetes. However, the use of multiple antipsychotic treatments makes the individualisation of specific risks associated with any other antipsychotic drug impossible.

Association between childhood trauma and multimodal early-onset hallucinations

Previous reports suggest that adverse events during childhood could be related to an array of psychiatric problems. Here, we question the relationship between childhood traumatic experiences and the sensory complexity of hallucinations in a cohort of 75 children and adolescents. We evidence a positive link between the number of sensory modalities involved in hallucinations and history of childhood trauma, even after controlling for the co-occurrence of suicidal ideation or the number of ICD-10 diagnoses. These findings support initiatives in which a routine exploration of traumatic events in childhood is performed when multimodal hallucinations are present.
