High Psychological Impact of Covid-19 on French Healthcare Workers: An Observational Cohort Study of PTSD, Depression and Burn-Out.

Introduction: The Covid-19 outbreak hit the world forcing public institutions to rethink their core functioning. Healthcare workers (HCWs) were particularly at risk for negative mental health outcomes, given their direct exposure to many pandemic-related stressors. Our study aimed to assess the psychological outcomes of French HCWs during the Covid-19 pandemic, including PTSD, depression and burn-out.

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.

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.

Dietary Patterns and Major Depression: Results from 15,262 Participants (International ALIMENTAL Study).

Background: Different patterns of food consumption may be associated with a differential risk of depression. Differences in dietary patterns between men and women and across different age groups have been reported, but their influence on the risk of depression has not been fully explored.

Objectives: To investigate the associations between dietary patterns and risk of depression across sex and age groups to identify vulnerable subpopulations, which may inform targeted prevention and intervention strategies.

Role of early life adversities in inflammation-related neuropsychiatric comorbidity in obesity.

A growing body of data highlights the key role of adiposity-related inflammation in the development of neuropsychiatric comorbidity in obesity. Nevertheless, despite similar levels of inflammation, only a subgroup of obese subjects is afflicted with neuropsychiatric symptoms, suggesting the contribution of additional vulnerability factors. In light of previous work suggesting the involvement of early life adversity (ELA), this study aims to determine whether ELA promotes the emergence of inflammation-related neuropsychiatric symptoms in a sample of obese subjects.

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.

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.

Adherence to clinical practice guidelines for using electroconvulsive therapy in elderly depressive patients.

Objectives: Electroconvulsive therapy (ECT) is one of the most effective treatments in mood disorders, mainly in major depressive episode (MDE) in the context of either unipolar (MDD) or bipolar disorder (BD). However, ECT remains a neglected and underused treatment. Older people are at high risk patients for the development of adverse drug reactions.

Cord serum cytokines at birth and children's trajectories of mood dysregulation symptoms from 3 to 8 years: The EDEN birth cohort.

There is growing evidence that imbalance immune activity plays a role in the development of neurodevelopmental and psychiatric disorders in children. Mood dysregulation (MD) is a debilitating transnosographic syndrome whose underlying pathophysiological mechanisms could be revealed by studying its biomarkers using the Research Domain Criteria (RDoC) model. Our aim was to study the association between the network of cord serum cytokines, and mood dysregulation trajectories in offsprings between 3 and 8 years of age.

French Society for Biological Psychiatry and Neuropsychopharmacology (AFPBN) guidelines for the management of patients with partially responsive depression and treatment-resistant depression: Update 2024.

Introduction: The purpose of this update is to add newly approved nomenclatures and treatments as well as treatments yet to be approved in major depressive disorder, thus expanding the discussions on the integration of resistance factors into the clinical approach.

Methods: Unlike the first consensus guidelines based on the RAND/UCLA Appropriateness Method, the French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) developed an update of these guidelines for the management of partially responsive depression (PRD) and treatment-resistant depression (TRD). The expert guidelines combine scientific evidence and expert clinicians' opinions to produce recommendations for PRD and TRD.

Axo-axonic cells in neuropsychiatric disorders: a systematic review.

Imbalance between excitation and inhibition in the cerebral cortex is one of the main theories in neuropsychiatric disorder pathophysiology. Cortical inhibition is finely regulated by a variety of highly specialized GABAergic interneuron types, which are thought to organize neural network activities. Among interneurons, axo-axonic cells are unique in making synapses with the axon initial segment of pyramidal neurons.

Crossed clinical features between eating disorders and types of bipolar disorder: Results from the FondaMental Advanced Centers of Expertise - Bipolar Disorder cohort.

Background: Eating disorders (EDs) are liable to alter the disease course of bipolar disorder (BD). We explored the crossed clinical features between EDs and BD, particularly as a function of BD type (BD1 vs. BD2).

Long-term benzodiazepine prescription in treatment-resistant depression: A national FACE-TRD prospective study.

Background: Benzodiazepine long-term use (BLTU) is a public health challenge. We lack data on the consequences of LBTU on the trajectory of treatment-resistant depression (TRD).

Objective: To determine the prevalence of BLTU in a nationwide non-selected population of patients with TRD, to determine the rate of patients succeeding at withdrawing benzodiazepines at one year and to determine if persistent BLTU is associated with poorer mental health outcomes.

EMDR for symptoms of depression, stress and burnout in health care workers exposed to COVID-19 (HARD): A study protocol for a trial within a cohort study.

Stressful events during a pandemic are a major cause of serious health problems, such as burnout, depression and posttraumatic stress disorder (PTSD) among health care workers (HCWs). During three years, HCWs, on the frontline to fight the COVID-19 pandemic, have been at an increased risk of high levels of stress, anxiety, depression, burnout and PTSD. Regarding potential psychological interventions, Eye Movement Desensitization & Reprocessing (EMDR) is a structured, strongly recommended therapy based on its well-known efficacy in reducing PTSD symptoms and anxiety.

Clinical and pharmacological correlates of caffeine consumption in subjects with schizophrenia - Data from the FACE-SZ cohort.

Caffeine is the most consumed psychoactive substance worldwide. Previous studies suggested higher caffeine consumption in subjects with schizophrenia spectrum disorders (SSD) as well as associations with symptoms, medication and medication side-effects. In a large and well-characterized sample of SSD subjects we explored the association between caffeine consumption and clinical (psychosis related, severity, general health) as well as pharmacological (antipsychotic treatment, sedation potential) variables.
