Incidence and predictors of metabolic syndrome onset in individuals with bipolar disorders: A longitudinal study from the FACE-BD cohort.

INTRODUCTION: Metabolic syndrome (MetS) is a cluster of components including abdominal obesity, hyperglycemia, hypertension, and dyslipidemia. MetS is highly prevalent in individuals with bipolar disorders (BD) with an estimated global rate of 32.6%. Longitudinal data on incident MetS in BD are scarce and based on small sample size. The objectives of this study were to estimate the incidence of MetS in a large longitudinal cohort of 1521 individuals with BD and to identify clinical and biological predictors of incident MetS. METHODS: Participants were recruited from the FondaMental Advanced Center of Expertise for Bipolar Disorder (FACE-BD) cohort and followed-up for 3 years. MetS was defined according to the International Diabetes Federation criteria. Individuals without MetS at baseline but with MetS during follow-up were considered as having incident MetS. A logistic regression model was performed to estimate the adjusted odds ratio and its corresponding 95% confidence interval (CI) for an association between each factor and incident MetS during follow-up. We applied inverse probability-of-censoring weighting method to minimize selection bias due to loss during follow-up. RESULTS: Among individuals without MetS at baseline (n = 1521), 19.3% developed MetS during follow-up. Multivariable analyses showed that incident MetS during follow-up was significantly associated with male sex (OR = 2.2, 95% CI = 1.7-3.0, p < 0.0001), older age (OR = 2.14, 95% CI = 1.40-3.25, p = 0.0004), presence of a mood recurrence during follow-up (OR = 1.91, 95% CI = 1.22-3.00, p = 0.0049), prolonged exposure to second-generation antipsychotics (OR = 1.56, 95% CI = 0.99, 2.45, p = 0.0534), smoking status at baseline (OR = 1.30, 95% CI = 1.00-1.68), lifetime alcohol use disorders (OR = 1.33, 95% CI = 0.98-1.79), and baseline sleep disturbances (OR = 1.04, 95% CI = 1.00-1.08), independently of the associations observed for baseline MetS components. CONCLUSION: We observed a high incidence of MetS during a 3 years follow-up (19.3%) in individuals with BD. Identification of predictive factors should help the development of early interventions to prevent or treat early MetS.

Functioning and neurocognition in very early and early-life onset bipolar disorders: the moderating role of bipolar disorder type.

Defining homogeneous subgroups of bipolar disorder (BD) is a major goal in personalized psychiatry and research. According to the neurodevelopmental theory, age at onset may be a key variable. As potential trait markers of neurodevelopment, cognitive and functional impairment should be greater in the early form of the disease, particularly type 1 BD (BD I). The age at onset was assessed in a multicenter, observational sample of 4190 outpatients with BD. We used a battery of neuropsychological tests to assess six domains of cognition. Functioning was measured using the Functioning Assessment Short Test (FAST). We studied the potential moderation of the type of BD on the associations between the age at onset and cognitive and functioning in a subsample of 2072 euthymic participants, controlling for potential clinical and socio-demographic covariates. Multivariable analyses showed cognition to not be impaired in individuals with early (21-30 years) and very early-life (before 14 years) onset of BD. Functioning was equivalent between individuals with early and midlife-onset of BD II and NOS but better for individuals with early onset of BD I. In contrast, functioning was not worse in individuals with very early-onset BD I but worse in those with very early-onset BD II and NOS. Early-life onset BDs were not characterized by poorer cognition and functioning. Our results do not support the neurodevelopmental view that a worse cognitive prognosis characterizes early-life onset BD. This study suggests that functional remediation may be prioritized for individuals with midlife-onset BD I and very early life onset BD 2 and NOS.

How to target disturbed identity in borderline patients? Self-identification program: A case study.

Borderline personality disorder (BPD) is a severe and relatively prevalent psychiatric disorder, responsible for high rates of suicidal behaviors. Disturbed identity appears as at the very core of this disorder, being inter-related with all other BPD features. Notably, from a dimensional perspective on mental disorders, one should realize that it is from our usual self-representation that we live all our daily experiences. Then, if the understanding of self-concept (or identity) is impaired, all the interventions implemented to decrease the self's suffering will subsequently be impaired. The purpose of the present case study was to illustrate the nine identity diffusion categories described by Jørgensen & Bøye (2022) and how the level of identity function can be improved in a third-wave cognitive and behavioral therapy targeting progressive correct self-identification.

Childhood trauma increases vulnerability to attempt suicide in adulthood through avoidant attachment.

BACKGROUND: Childhood trauma and affective disorders are known risk factors for adult suicidal behavior. Studies have shown a mediating effect of insecure attachment on the effect of childhood trauma and suicidal behavior but so far it is not clear whether this effect is related to an attachment dimension (anxiety, avoidance). AIM: The present study sought to examine the mediating effect of attachment anxiety and avoidance on suicidal behavior. METHODS: We analyzed data on childhood trauma, attachment style, depression severity, presence of prior suicide attempts and current suicide ideation from 96 patients diagnosed with an affective disorder. Two mediation analyses were conducted to assess the effect of childhood trauma on 1) prior suicide attempts and 2) current suicidal ideation through its effect on attachment. RESULTS: We found that childhood trauma had a complete mediated effect on the presence of prior suicide attempts through its effect on avoidant attachment (a1b1 = 0.0120, 95%-CI [0.0031, 0.0276]). However, only emotional abuse had a direct influence on suicidal ideation (c' = 0.0273, p < 0.01) without any indirect effect of anxious or avoidant attachment. LIMITATIONS: Variables were not assessed in a prospective way and sample size was small. CONCLUSIONS: Our findings suggest that individuals with avoidant attachment and childhood trauma are likely to present a high suicide risk. Since avoidant attachment is associated with altered perceptions and eventual rejection of social support, we recommend to screen for attachment early and to engage patients in therapeutical approaches focusing on the client-therapist alliance.

Sexual orientation, gender: Where is the problem? Nowhere! Correct self-identification and minority stigma.

PURPOSE: Self-concept, at the core of minority stress, is associated with negative mental health outcomes. METHODS: We aimed to assess the effectiveness of a one-shot third-wave CBT intervention targeting correct self-identification to address suffering related to minority stress. The study population included 172 participants (n = 98 heterosexuals, n=13 transgenders). The intervention consisted of a 90 minutes conference including overview of LGBT's suffering related to distal and proximal factors, a wisdom understanding of the root of suffering (mistaken self-identification) followed by a Questions & Answers session. Participants completed online self-questionnaires assessing sociodemographic data, acceptance by others (external) and oneself (internal) for sexual orientation and gender variables before the conference, immediately after the conference, and three months later. RESULTS: The conference helped to improve external acceptance of transgender for the whole sample, especially among the majority group. Those belonging to the minority (LGBT) had a positive benefit from the conference by reducing their fear of judgment. Adding a Q&A session to the conference failed to show any additional benefits. CONCLUSION: A specific wisdom-based self-identification conference appears to be an effective and low-cost intervention to target minority stigma, and therefore mental health and social integration of LGBT people.

How Does COVID-19 Affect the Neurobiology of Suicide?

PURPOSE OF REVIEW: The aim of this review was to analyze COVID-19 effect on the biological features of suicidal vulnerability and its interaction with suicide-related biological pathways. We carried out a narrative review of international publications on the interactions of COVID-19 with the biological bases of suicide. RECENT FINDINGS: We hypothesize that SARS-CoV-2 interacts with multiple biological processes that underlie suicidal behavior, such as the renin-angiotensin system, nicotinic receptors, and central and systemic inflammation. Social distancing measures may also worsen subjective or objective social disconnection, thus increasing the risk of suicide. Interestingly, the drugs used to prevent suicide could be promising options to counteract brain damage caused by this coronavirus. SARS-CoV-2 interacts with multiple biological pathways involved in suicide and opens a new window for understanding the suicidal process. The development of suicide prevention treatments in the context of a pandemic may benefit from knowledge on these interactions.

Prevalence and impact of patient suicide in psychiatrists: Results from a national French web-based survey.

BACKGROUND: Patient suicide (PS) is known to be a frequent and challenging occupational hazard for mental health professionals. No study previously explored the prevalence and impact of PS in a large sample of French psychiatrists. METHOD: A national web-based survey was performed between September and December 2019 to assess (a) the prevalence of the exposure to PS, (b) the emotional, traumatic and professional impacts of PS, and (c) the perceived support in the aftermath of PS in French psychiatrists. Participants were contacted through email to answer the online 62-item questionnaire, including a measure of traumatic impact through the Impact of Event Scale-Revised. Emotional and professional impacts and perceived support were assessed through dedicated items. RESULTS: A total of 764 psychiatrists fully completed the survey. Of them, 87.3% reported an exposure to PS and 13.7% reported PTSD symptoms afterward. Guilt, sadness and shock were the most frequent emotions. Among the exposed psychiatrists, 15.1% have temporarily considered changing their career path. The most emotionally distressing PS occurred during their ten first years of practice or during residency. A total of 37.1% of respondents felt unsupported and 50.4% reported that no team meeting had been organized in the aftermath. The feeling of responsibility for the death was strongly associated with negative impacts. CONCLUSION: Our results entail considerations to prevent negative mental health outcomes in psychiatrists after PS. Notably, our results advocate for the implementation of educational programs during psychiatric residency and postvention programs in healthcare settings to effectively help psychiatrists in dealing with PS.

Exploring the boundaries between borderline personality disorder and suicidal behavior disorder.

OBJECTIVE: To compare clinical traits of suicidal vulnerability among in-patients with suicidal behavior disorder (SBD) with and without borderline personality disorder (BPD). METHOD: we recruited adult patients with SBD, consecutively and voluntarily hospitalized in a specialized unit for affective disorders and suicidal behavior between July and October 2016. Ninety-two inpatients having attempted suicide within the past 2 years were divided into two subgroups according to the presence or absence of BPD. Clinical vulnerability traits for suicidal behavior were assessed. RESULTS: Half of the patients with SBD also had BPD. Patients with BPD were nine times more likely to be major suicide repeaters compared to those without. They were also more likely to display clinical and psychological vulnerability traits for suicidal behavior, even after considering potential confounders. Emotional dysregulation, shame-proneness, impulsiveness, preoccupied attachment pattern, and childhood trauma were high in both groups, but significantly increased in those with (vs. without) BPD status. Psychological traits remained stable in SBD-BPD patients, regardless of the time since the last suicide attempt (i.e. SBD in recent vs. early remission). CONCLUSIONS: Clinical and psychological traits associated with suicidal vulnerability are present in all SBD patients compared to non-suicidal populations, but comorbidity with BPD is associated with particularly high scores. BPD could be considered as a specifier for SBD diagnoses.

Somatic assessment of one hundred inpatients in a psychiatric crisis unit: A retrospective observational study.

OBJECTIVES: Compared to the general population, psychiatric patients are more exposed to physical illness but have reduced access to care. METHODS: We conducted a descriptive study in Montpellier between November 2011, 2nd and December 2012, 21st. Every Wednesday and Friday, the last two inpatients admitted in the psychiatric post-emergency unit of the University Hospital of Montpellier were assessed by a general practitioner and included in the study. This unit takes care of suicidal patients suffering from mood and/or personality disorders. The general practitioner assessed lifetime somatic history, current somatic comorbidities and medical follow-up for non-psychiatric issues. RESULTS: One hundred patients were included. The sample consisted of 81% women with a mean age of 43 years (18-79 years). The majority of patients had a lifetime history of somatic disease (96%) and was followed by a general practitioner (99%). Six patients had no met general practitioner for at least one year. Dyslipidemia was reported in 32 patients, among those only one patient was on lipid-lowering drug (96.88%). Among patients with impaired dental condition, 29 (55.77%) had not met a dentist for at least one year. Among those with impaired near visual acuity and/or impaired distance visual acuity, 19 (65.52%) had not met an ophthalmologist for at least one year. CONCLUSION: Although detected, somatic comorbidities seem outsourced in psychiatric patients. Greater awareness among different health professionals about the medical care of such patients could improve healthcare management and life expectancy.

[Suicidal behavior in light of COVID-19 outbreak: Clinical challenges and treatment perspectives]. / Épidémie de COVID-19 et prise en charge des conduites suicidaires : challenge et perspectives.

OBJECTIVE: The COVID-19 pandemic affected today more than 3,000,000 worldwide, and more than half of humanity has been placed in quarantine. The scientific community and the political authorities fear an epidemic of suicide secondary to this crisis. The aim of this review is to analyze the impact of the COVID-19 pandemic on the dimensions of the suicidal process and its interaction with the various risk factors. We also propose innovative strategies to manage suicidal behavior in the context of pandemic. METHODS: We carried out a narrative review of international publications dealing with major pandemics (COVID-19, SARS) and their influence on suicidal vulnerability. RESULTS: Many factors are likely to increase the emergence of suicidal ideation and suicide attempts during this crisis. Social distancing and quarantine could increase the feeling of disconnection and the perception of social pain in vulnerable individuals. Some populations at high suicidal risk could be further impacted by the current pandemic: the elderly, medical staff and individuals exposed to economic insecurity. Several innovative tools adapted to the constraints of social distancing and quarantine may prevent suicide risk: e-health, VigilanS, buddhist-derived practices and art engagement. CONCLUSIONS: This unprecedented crisis may interact with certain dimensions of the suicidal process. However, it is time to innovate. Several suicide prevention tools all have their place in new modes of care and should be tested on a large scale.

Collaborative meta-analysis finds no evidence of a strong interaction between stress and 5-HTTLPR genotype contributing to the development of depression.

The hypothesis that the S allele of the 5-HTTLPR serotonin transporter promoter region is associated with increased risk of depression, but only in individuals exposed to stressful situations, has generated much interest, research and controversy since first proposed in 2003. Multiple meta-analyses combining results from heterogeneous analyses have not settled the issue. To determine the magnitude of the interaction and the conditions under which it might be observed, we performed new analyses on 31 data sets containing 38 802 European ancestry subjects genotyped for 5-HTTLPR and assessed for depression and childhood maltreatment or other stressful life events, and meta-analysed the results. Analyses targeted two stressors (narrow, broad) and two depression outcomes (current, lifetime). All groups that published on this topic prior to the initiation of our study and met the assessment and sample size criteria were invited to participate. Additional groups, identified by consortium members or self-identified in response to our protocol (published prior to the start of analysis) with qualifying unpublished data, were also invited to participate. A uniform data analysis script implementing the protocol was executed by each of the consortium members. Our findings do not support the interaction hypothesis. We found no subgroups or variable definitions for which an interaction between stress and 5-HTTLPR genotype was statistically significant. In contrast, our findings for the main effects of life stressors (strong risk factor) and 5-HTTLPR genotype (no impact on risk) are strikingly consistent across our contributing studies, the original study reporting the interaction and subsequent meta-analyses. Our conclusion is that if an interaction exists in which the S allele of 5-HTTLPR increases risk of depression only in stressed individuals, then it is not broadly generalisable, but must be of modest effect size and only observable in limited situations.

[Social pain at the core of suicidal behavior]. / La douleur sociale au centre des conduites suicidaires.

BACKGROUND: Intolerable pain is often reported in suicide notes. Moreover, the frequency of life events preceding a suicidal act is high, especially interpersonal difficulties. Such adversity is the source of psychological or social pain. METHODS: We propose a narrative review to discuss the role of pain in the suicidal process while having a focus on social ties. RESULTS: Using Ecological Momentary Assessment in suicide attempters it has been shown that being alone increased suicidal ideation while being with close others significantly reduced this risk. At a neuroanatomical level, suicidal vulnerability is associated with dysfunctional insula activation during social exclusion, a region involved in social and physical pain processing. Social pain elicited by social exclusion or devaluation shares common neurobiological patterns with physical pain. It is also an exemplar of psychological pain. Despite the complexity of its definition, higher psychological pain levels are associated with suicidal ideation and acts. Finally, intense physical pain or chronic pain are strong risk factors of suicidal ideation and act. Interestingly, suicide notes often report the existence of an intolerable pain. Presence of psychological pain and difficulties in communication predict the lethality and seriousness of suicide attempts. Moreover, presence of psychological pain is associated with more impulsive choices in suicidal patients, suggesting that a suicidal act is a means to escape intolerable suffering despite negative long-term consequences (i.e. death). Analgesics are usually used to get relief from pain but are also frequently involved in suicidal overdoses. It has been shown that opioid analgesics are associated with an increased risk of suicide. Higher consumption of opioid analgesics has been shown in suicidal patients in comparison to patients with history of depression but no suicidal act and healthy controls whereas non-suicidal patients were those reporting higher presence of pain in comparison to healthy controls. It may suggest that opioids are being used by suicidal patients to get relief from psychological/social pain rather than from physical pain. Involvement of opioidergic system in suicidal process opens new therapeutic strategies. Recently, the time-limited, short-term use of very low dosages of sublingual buprenorphine (vs. placebo) was associated with decreased suicidal ideation and mental pain in severely suicidal patients without substance abuse. In a randomized controlled trial comparing a 7-week acceptance and commitment therapy (ACT) versus relaxation group, as adjunct to treatment as usual for adult outpatients suffering from a current suicidal behavior disorder, ACT has shown its effectiveness in reducing suicidal ideation and psychological pain. Evidence indicates that maintaining contact either via letter, postcard or telephone with at-risk adults following discharge from care services after a suicide attempt can reduce reattempt risk. Based on these results, a preventive program of recontact for suicide attempters, VIGILANS, has been developed in France in usual care. CONCLUSION: The approach of the suicidal issue by the angle of pain and social disconnection offers new advances to improve clinical assessment, to identify new biological pathways involved in suicidal risk, and to propose innovative therapeutic and preventive actions.

Affect lability predicts occurrence of suicidal ideation in bipolar patients: a two-year prospective study.

OBJECTIVE: The aim of our study was to investigate, in bipolar patients, whether affect lability was associated with suicidal ideation incidence during 2-year follow-up, and which subtype of affect lability was associated with suicidal ideation. METHOD: A total of 319 euthymic or mildly depressed bipolar outpatients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups according to the occurrence of suicidal ideation during a 2-year follow-up. Affect lability was assessed by the French version of the Affect Lability Scale. RESULTS: Bipolar patients with high affect lability were more likely to report suicidal ideation during follow-up, even after adjustment for age, study level, rapid cycling, current depression level, anxiety disorder, and lifetime history SA (OR = 2.47; 95% CI [1.15-5.30], P = 0.01). The risk of suicidal ideation increased with the level of affect lability. More specifically, the propensity to switch from neutral to elation affect, from anxious to depressive affect (or inversely), and from neutral to anger affect predicted suicidal ideation. CONCLUSION: Reducing affective lability could become a new therapeutic target of suicidal prevention in bipolar disorder.

Clinical and neuropsychological characteristics of euthymic bipolar patients having a history of severe suicide attempt.

OBJECTIVE: Identifying bipolar patients at high-suicide risk is a major health issue. To improve their identification, we compared dimensional and neuropsychological profile of bipolar patients with or without history of suicide attempt, taking into account suicidal severity (i.e. admission to intensive ward). METHOD: A total of 343 adult euthymic bipolar out-patients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into three subgroups: 214 patients without history of suicide attempt, 88 patients with past history of non-severe suicide attempt and 41 patients with past history of severe suicide attempt. General intellectual functioning, speed of information processing, verbal learning and memory, verbal fluency and executive functioning were assessed. RESULTS: Severe suicide attempters had lower affective intensity and lability than non-severe attempters. Severe suicide attempters outperformed non-severe attempters for verbal learning and non-attempters for Stroop word reading part after adjustment for study centre, age, gender, educational level, antipsychotics use, depression score, anxious and addictive comorbidities. CONCLUSION: Neuropsychological tasks commonly used to assess bipolar patients do not seem accurate to identify suicide attempters in euthymic patients. In the future, decision-making and emotional recognition tasks should be assessed. Moreover, clinical and neuropsychological profiles should be considered together to better define suicidal risk.

Increased severity of suicidal behavior in impulsive aggressive patients exposed to familial adversities.

BACKGROUND: The mechanisms by which childhood abuse and family history of suicidal behavior (FHS) lead to an increased risk of suicidal behavior are still unknown. Impulsive aggression may play an intermediate role. We investigated whether greater scores for aggression and impulsivity might be associated with the effects of FHS and/or childhood abuse on the severity of suicidal behavior. METHOD: We examined the scores of three scales measuring impulsive aggression in a sample of 696 suicide attempters. We compared the highest and lowest scores with regard to reports of childhood abuse and FHS using adjusted multinomial regression models. Genetic polymorphisms of the serotonergic system known to be associated with impulsive aggression were also analyzed. RESULTS: Patients with high impulsive aggressive scores showed significant differences in sociodemographic, clinical and suicidal features compared with patients with low impulsive aggressive scores. Adjusted results showed that combinations of some types of childhood abuse and FHS, particularly emotional abuse and emotional neglect, are associated with high impulsivity and hostility scores. The SS genotype of the serotonin transporter gene (5-HTTLPR) was associated with high levels of impulsivity when the subjects reported emotional abuse [odds ratio (OR) 5.55, 95% confidence interval (CI) 1.75-17.5] or physical abuse (OR 5.03, 95% CI 1.50-16.9) in their childhood. CONCLUSIONS: Our results support the role of impulsive aggression as one of the links that may connect childhood abuse and FHS with severity of suicidal behavior.

Risk factors of suicide re-attempt: A two-year prospective study.

BACKGROUND: History of suicide attempt (SA) is the strongest predictor of a new SA and suicide. It is primordial to identify additional risk factors of suicide re-attempt. The aim of this study was to identify risk factors of suicide re-attempt in patients with recent SA followed for 2 years. METHODS: In this multicentric cohort of adult inpatients, the median of the index SA before inclusion was 10 days. Clinicians assessed a large panel of psychological dimensions using validated tools. Occurrence of a new SA or death by suicide during the follow-up was recorded. A cluster analysis was used to identify the dimensions that best characterized the population and a variable "number of personality traits" was created that included the three most representative traits: anxiety, anger, and anxious lability. Risk factors of re-attempt were assessed with adjusted Cox regression models. RESULTS: Among the 379 patients included, 100 (26.4 %) re-attempted suicide and 6 (1.6 %) died by suicide. The two major risk factors of suicide re-attempt were no history of violent SA and presenting two or three personality traits among trait anxiety, anger and anxious lability. LIMITATIONS: It was impossible to know if treatment change during follow-up occur before or after the re-attempt. DISCUSSION: One of the most important predictors of re-attempt in suicide attempters with mood disorders, was the presence of three personality traits (anger, anxiety, and anxious lability). Clinicians should provide close monitoring to patients presenting these traits and proposed treatments specifically targeting these dimensions, especially anxiety.

Comparative analysis of anticholinergic burden scales to explain iatrogenic cognitive impairment and self-reported side effects in the euthymic phase of bipolar disorders: Results from the FACE-BD cohort.

Bipolar disorders (BD) are characterized by cognitive impairment during the euthymic phase, to which treatments can contribute. The anticholinergic properties of medications, i.e., the ability of a treatment to inhibit cholinergic receptors, are associated with cognitive impairment in elderly patients and people with schizophrenia but this association has not been well characterized in individuals with remitted BD. Moreover, the validity of only one anticholinergic burden scale designed to assess the anticholinergic load of medications has been tested in BD. In a literature review, we identified 31 existing scales. We first measured the associations between 27 out of the 31 scales and objective cognitive impairment in bivariable regressions. We then adjusted the bivariable models with covariates: the scales significantly associated with cognitive impairment in bivariable and multiple logistic regressions were defined as having good concurrent validity to assess cognitive impairment. In a sample of 2,031 individuals with euthymic BD evaluated with a neuropsychological battery, two scales had good concurrent validity to assess cognitive impairment, whereas chlorpromazine equivalents, lorazepam equivalents, the number of antipsychotics, or the number of treatments had not. Finally, similar analyses with subjective anticholinergic side-effects as outcome variables reported 14 scales with good concurrent validity to assess self-reported peripheral anticholinergic side-effects and 13 to assess self-reported central anticholinergic side-effects. Thus, we identified valid scales to monitor the anticholinergic burden in BD, which may be useful in estimating iatrogenic cognitive impairment in studies investigating cognition in BD.

The impulsiveness level influences the salivary cortisol response and social stress sensitivity in suicidal patients.

INTRODUCTION: Suicide attempters (SA) are more vulnerable to social stress and show disturbed cortisol response in stressful conditions compared with psychiatric and healthy controls. Recent data suggest that this dysregulation might be related to impulsivity traits. However, little is known about the emotional consequences of social stress in SA exposed to stress. OBJECTIVES: The aim of our study was to evaluate the cortisol and emotional responses to social stress in patients with depression with and without suicide attempt, by taking into account impulsivity traits and depression severity. METHODS: 67 adult women (41 SA and 26 affective controls (AC,i.e. without suicide attempt history)) with lifetime history of major depressive episode were included. Patients performed the Trier Social Stress Test (TSST), a well-validated social stress task. Patients provided seven saliva samples, to measure the cortisol response, and filled in questionnaires to assess psychological pain, positive and negative mood, and anxiety at different time points (from 10 min before to 120 min after the TSST). Moderated regression models were used including suicide attempt history, depression severity, and impulsivity as independent variables and their interactions. RESULTS: In patients with low depression and high impulsivity, salivary cortisol response during the TSST was higher in SA than in AC (p < .001). Psychological pain, negative mood, and anxiety were increased in all patients just after the TSST, followed by a decrease at 120 min. Positive mood recovery was slower in SA, and in patients with high impulsivity and low depression level (p < .001). CONCLUSIONS: Impulsivity traits have an important role in suicidal vulnerability in stress conditions. Impulsivity traits might help to differentiate patients at risk of suicide who are highly sensitive to stress when depression level is low. Higher impulsiveness may increase the sensitivity to emotional distress that translates into inadequate physiological responses.

Key findings on bipolar disorders from the longitudinal FondaMental Advanced Center of Expertise-Bipolar Disorder (FACE-BD) cohort.

BACKGROUND: The FACE-BD cohort is an observational cohort of individuals with bipolar disorders (BD) who benefited from a systematic evaluation with evidence-based treatment recommendations and who were followed-up every year for 3 years in France. The objectives were to describe the lifetime course of BD, associated psychiatric and somatic comorbidities, and cognition profile. This cohort aims to identify clinical/biological signatures of outcomes, trajectories of functioning and transition between clinical stages. This article summarizes 10 years of findings of the FACE-BD cohort. METHOD & RESULTS: We included 4422 individuals, all having a baseline assessment, among which 61.2% had at least one follow-up visit at either one, two or three years. A subsample of 1200 individuals had at least one biological sample (serum, plasma, DNA). Assessments include family history of psychiatric disorders, psychiatric diagnosis, current mood symptoms, functioning, hospitalizations, suicidal attempts, physical health, routine blood tests, treatment history, psychological dimensions, medico-economic data and a cognitive assessment. Studies from this cohort illustrate that individuals with BD display multiple coexistent psychiatric associated conditions including sleep disturbances, anxiety disorders, substance use disorders and suicide attempts as well as a high prevalence of metabolic syndrome. During follow-up, we observed a 55% reduction of the number of days of hospitalization and a significant improvement in functioning. CONCLUSIONS: The FACE-BD cohort provides a strong research infrastructure for clinical research in BD and has a unique position among international cohorts because of its comprehensive clinical assessment and sustainable funding from the French Ministry of Health.

Influence of childhood maltreatment on prevalence, onset, and persistence of psychiatric comorbidities and suicide attempts in bipolar disorders.

BACKGROUND: Psychiatric comorbidities and suicide attempts are highly prevalent in Bipolar Disorders (BD). We examined the associations between childhood maltreatment, psychiatric comorbidities, and suicide attempts, in terms of lifetime prevalence, sequence of onset, and current symptoms. METHODS: We assessed 3,047 individuals with BD for suicide attempts, anxiety disorders, substance use disorders, and eating disorders. Participants completed a self-report for the assessment of childhood maltreatment. Associations between childhood maltreatment and characteristics of comorbidities (lifetime prevalence, current symptoms, and age at onset) were examined using logistic regressions and network analyses. RESULTS: Psychiatric comorbidities were frequent with a mean number per individual of 1.23 (SD = 1.4). Most comorbidities occurred prior to the onset of BD. Participants who reported higher levels of childhood maltreatment had more frequent and multiple comorbidities, which were also more currently active at inclusion. Childhood maltreatment did not decrease the age of onset of comorbidities, but was associated with a faster accumulation of comorbidities prior to the onset of BD. Logistic regression and network analyses showed that emotional abuse and sexual abuse might play a prominent role in the lifetime prevalence of psychiatric comorbidities and suicide attempts. CONCLUSIONS: Childhood maltreatment was associated with suicide attempts, and with frequent, multiple, and persistent psychiatric comorbidities that accumulated more rapidly prior to the onset of BD. Hence, childhood maltreatment should be systematically assessed in individuals with BD, in particular when the course of the disorder is characterized by a high comorbid profile or by a high suicidality.
