Polygenic risk scores for severe psychiatric disorders in bipolar disorders: associations with the clinical and dimensional expression, interactions with childhood maltreatment and mediation models.

Polygenic risk scores (PRSs) for several psychiatric disorders have been associated with the clinical presentation of bipolar disorder (BD). PRSs have also been suggested to moderate the associations between childhood maltreatment and BD severity. In this study, we investigated how PRSs for BD, schizophrenia, major depressive disorders (MDD) and attention-deficit/hyperactivity disorder (ADHD) might disentangle the clinical and dimensional heterogeneity of BD in a sample of 852 affected individuals.

Flowers for Algernon: How metacognition affects quality of life in schizophrenia. Structural equation modeling with the FACE-SZ cohort.

Background And Hypothesis: We examined the association between metacognitive performance, functioning, and quality of life (QoL) in schizophrenia using structural equation model analyses.

Study Design: A sample of 249 participants was assessed for symptoms, functioning, QoL, and both objective and subjective cognitive performance. Metacognitive performance was defined as the adequation between objective and subjective measures of cognitive performance.

Bright Light Therapy in the Morning or Midday for the Treatment of Nonseasonal Depression in Bipolar Disorder (LuBi): A Dose-Escalation Phase 1/2 Randomized Double-Blind Trial.

This dose-escalation study aimed to evaluate the tolerance (hypomanic symptoms) and efficacy of bright light therapy (BLT) in depressed patients with bipolar disorder (BD) with mood stabilizers, using different schedules (duration and escalation), applied in morning or midday. Patients with BD I or II () followed a 1-week placebo phase and were randomized to morning or midday BLT with dose escalation from 7.5 to 45 minutes/d, until September 2023.

Clinical and inflammatory markers associated with metabolic dysfunction-associated fatty liver disease in a cohort of individuals with chronic schizophrenia (FACE-SZ).

Aims: Recent studies on Metabolic dysfunction-associated fatty liver (MAFLD) in schizophrenia show inconsistent findings, often based on small or specific samples. This study aims to assess the prevalence of MAFLD and its sociodemographic, clinical, and treatment-related risk factors in a large cohort of chronic patients with schizophrenia. A secondary goal is to identify an immuno-inflammatory signature associated with MAFLD.

Association Between Adult Sexual Assault and Psychiatric Disorders: Results From the National Epidemiologic Survey on Alcohol and Related Conditions-III.

Sexual assault is a significant public health issue with high prevalence rates, particularly among women. Previous research suggests strong associations between sexual assault and psychiatric disorders, but studies focusing on adult sexual assault (ASA) and its sex specific consequences are limited. To estimate the prevalence of ASA in the US and assess its associations with psychiatric disorders and quality of life, focusing on sex differences.

Pro-inflammatory processes and metabolic syndrome: combined risk of resistance to treatment in patients with schizophrenia from the FACE-SZ cohort.

Schizophrenia (SZ) is characterized by a variable clinical expression and course peppered/hampered by severe complications. In particular, resistance to treatment (overall-TRS, treatment resistant SZ including UTRS, ultra-TRS) and metabolic syndrome (MetS) are highly prevalent, and both demonstrated to be underpinned, at least partly, by pro-inflammatory processes. Given that such processes also underlie SZ per se, we hypothesized that potential inter-twinning between SZ- and MetS-related inflammatory processes may exert a combined effect on the risk of having overall-TRS/UTRS.

Exploring the Association Between Residual Mood Symptoms and Self-Reported Side Effects in the Euthymic Phase of Bipolar Disorders: A Cross-Sectional Network Analysis.

Bipolar disorders (BD) are characterized by mood symptoms that can worsen medication side effects. We aimed to study the association between residual mood signs and self-reported side effects in the euthymic phase of BD. We assessed residual mood signs using the Montgomery-Asberg Depression Rating scale (MADRS) and Young Mania Rating scale (YMRS) and self-reported side effects using the Patient-Rated Inventory of Side Effects (PRISE-M) for 880 males and 1369 females with BD.

QT Interval, Antipsychotics and Correlates Among Patients with Schizophrenia: Cross-Sectional Data from the Multicentric Real-World FACE-SZ.

Background: The life expectancy of patients with schizophrenia is reduced, partly due to cardiovascular diseases. Antipsychotics are associated with QT interval prolongation, which is a risk factor for arrhythmia and cardiac arrest. The differences between antipsychotic with regard to QT interval prolongation are not well understood.

Clinical features and comorbidities associated with migraine in bipolar disorder: Results from the FACE-BD cohort.

Introduction: Individuals with bipolar disorder (BD) frequently experience comorbid medical conditions, with migraine being among the most common. While research on migraine prevalence in BD is growing, the associated clinical features, comorbidities, and treatments remain underexplored and sometimes inconsistent. This study aimed to investigate the clinical features and comorbidities associated with migraine in a large cohort of adults with BD.

Prediction of relapse in a French cohort of outpatients with schizophrenia (FACE-SZ): Prediction, not association.

Background: Schizophrenia (SZ) commonly manifests through multiple relapses, each impeding the path to recovery and incurring personal and societal costs. Despite the identification of various risk factors associated to the risk of relapse, the development of accurate algorithms predictive of relapse has been limited, partly due to inadequate statistical methods. Additionally, despite the wealth of data showing strong associations between inflammation and schizophrenia, the two existing studies failed to demonstrate whether inflammatory parameters could predict relapse.

Prevalence, correlates and comorbidity of irritability in adults with major depressive episode in the U.S. population (2012-2013).

Background: Irritability has been documented in major depressive episodes (MDE) in children and adolescents. However, the prevalence of irritability in MDE and its clinical correlates remain unknown in adults.

Method: We showed associations between the prevalence of irritability and its sociodemographic characteristics in a representative U.

Diet quality and associations with lactate and metabolic syndrome in bipolar disorder.

Background: Nutrition is largely affected in bipolar disorder (BD), however, there is a lack of understanding on the relationship between dietary categories, BD, and the prevalence of metabolic syndrome. The objective of this study is to examine dietary trends in BD and it is hypothesized that diets with increased consumption of seafood and high-fiber carbohydrates will be correlated to improved patient outcomes, and a lower frequency of metabolic syndrome.

Methods: This retrospective cohort study includes two French cohorts.

Distressing memories: A continuum from wellness to PTSD.

Background: Exposure to traumatic events is a frequent source of distress, provoking isolated symptoms such as distressing memories (DM) to full-blown post-traumatic stress disorder (PTSD). We aimed to assess the continuum theory using DM as an isolated symptom, and to examine trauma consequences in a exposed to traumatic events.

Methods: Using data from the National Epidemiologic Study of Alcohol and Related Conditions III, we assessed the prevalence of DM in a trauma exposed sample, and examined their sociodemographic and lifetime psychiatric correlates, comparing three groups: (i) controls (no DM, no PTSD); (ii) participants with isolated DM without PTSD; (iii) participants with PTSD.

Age of onset of major depressive episode and association with lifetime psychiatric disorders, health-related quality of life and impact of gender: A cross sectional and retrospective cohort study.

Objective: To assess the long-term impact of the age of onset (AOO) of the first major depressive episode (MDE) according to 3 age groups and considering gender.

Methods: Data were extracted from NESARC III, a representative U.S.

Modeling longitudinal relationships between sleep disturbances and depressed mood in postpartum: A cross-lagged panel design.

Background: This short communication explores the interrelationships between depressed mood and sleep disturbances in one-year postpartum period.

Methods: Utilizing data from the Interaction of Gene and Environment of Depression during PostPartum Cohort (IGEDEPP) involving 3310 French postpartum women, we employed a cross-lagged panel model (CLPM) to analyze the relationships between these two symptoms, across three time points (immediate postpartum [<1 week after delivery], early postpartum [<2 months after delivery], and late postpartum [2 months to 1 years after delivery]).

Results: Depressed mood significantly influences sleep disturbances in late postpartum (β = 0.

Comparative analysis of anticholinergic burden scales to explain iatrogenic cognitive impairment in schizophrenia: results from the multicenter FACE-SZ cohort.

Aim: The anticholinergic properties of medications are associated with poorer cognitive performance in schizophrenia. Numerous scales have been developed to assess anticholinergic burden and yet, there is no consensus indicating which anticholinergic burden scale is more relevant for patients with schizophrenia. We aimed to identify valid scales for estimating the risk of iatrogenic cognitive impairment in schizophrenia.

Predictors of Functional Impairment in Bipolar Disorder: Results From 13 Cohorts From Seven Countries by the Global Bipolar Cohort Collaborative.

Objectives: Persistent functional impairment is common in bipolar disorder (BD) and is influenced by a number of demographic, clinical, and cognitive features. The goal of this project was to estimate and compare the influence of key factors on community function in multiple cohorts of well-characterized samples of individuals with BD.

Methods: Thirteen cohorts from 7 countries included = 5882 individuals with BD across multiple sites.

Postpartum blues: a predictor of postpartum depression, from the IGEDEPP Cohort.

Background: To identify the different factors associated with postpartum blues and its association with postpartum depression, from a large French cohort.

Methods: We conducted an analysis of the Interaction Gene Environment in Postpartum Depression cohort, which is a prospective, multicenter cohort including 3310 women. Their personal (according to the Diagnostic and Statistical Manual, fifth edition [DSM-5]) and family psychiatric history, stressful life events during childhood, pregnancy, and delivery were collected.

Factors associated with lamotrigine concentration/dose ratio in individuals with bipolar disorders.

Monitoring of lamotrigine levels is recommended in epilepsy. However, in bipolar disorders (BD), no study has described the therapeutic range in daily practice and factors being associated to it. We used retrospective data of individuals with BD, treated with lamotrigine, and included in the FondaMental Advanced Centers of Expertise for Bipolar Disorders cohort.
