Vagus nerve stimulation lead durability: Insights from an extensive monocentric single-operator adult series.

Background: Vagus nerve stimulation (VNS) is an established surgical option for neuromodulation. Lead failure is a significant complication mainly reported in children.

Methods: We conducted a retrospective review of all VNS-related surgeries for refractory epilepsy in adults performed by a single experienced surgeon at a French national referral center from November 2011 to March 2023.

Opinions of French psychiatrists on the regulatory status of cannabis: Results from the "PsyCan - Encéphale" national online survey.

Objective: To explore the opinions of French psychiatrists toward the legalization of medical or recreational use of cannabis in France.

Methods: Psycan was an anonymous Internet survey conducted between September 28, 2021 and March 29, 2022, among subscribers of the Encéphale Online community, i.e.

Predictors of postoperative epidural hematomas after custom-made porous hydroxyapatite cranioplasty: a single-center experience of 194 consecutive cases.

Cranioplasty is important for improving cosmesis and functional recovery after decompressive craniectomy. We assessed the incidence and predictors of post-cranioplasty epidural hematomas requiring surgical evacuation. A single-institution, retrospective study enrolled 194 consecutive patients who underwent a cranioplasty using custom-made hydroxyapatite between February 2008 and April 2022.

A Preoperative Scoring System to Predict Function-Based Resection Limitation Due to Insufficient Participation During Awake Surgery.

Background: Failure in achieving a function-based resection related to the insufficient patient's participation is a drawback of awake surgery.

Objective: To assess preoperative parameters predicting the risk of patient insufficient intraoperative cooperation leading to the arrest of the awake resection.

Methods: Observational, retrospective, multicentric cohort analysis enrolling 384 (experimental dataset) and 100 (external validation dataset) awake surgeries.

A new ranking index to identify the work-related psychosocial factors most impacting mental health: a cross-sectional study.

Objectives: In modern professional life, mental health prevention and promotion have become a major challenge for decision-makers. Devising appropriate actions requires better understanding the role played by each work-related psychosocial factor (WPSF). The objective of this study was to present a relevant tool to hierarchise WPSFs that jointly takes into account their (impact on mental health) and their (the proportion of the population exposed to WPSF).

BRET Analysis of GPCR Dimers in Neurons and Non-Neuronal Cells: Evidence for Inactive, Agonist, and Constitutive Conformations.

G-protein-coupled receptors (GPCRs) are dimeric proteins, but the functional consequences of the process are still debated. Active GPCR conformations are promoted either by agonists or constitutive activity. Inverse agonists decrease constitutive activity by promoting inactive conformations.

[Smoking cessation services during "Mois sans tabac": Smokers' profile and effectiveness].

Introduction: In November 2016, France implemented "Mois sans tabac", with the objective of promoting smoking cessation in November for at least one month. This study consisted of: (1) the description of the characteristics of smokers registered in the French cessation database during November 2014-2015 compared to November 2016-2017; (2) the comparison of abstinence factors between the two periods.

Methods: We used data from CDTnet with 4659 registered adults' smokers who came for a first visit in November from 2014 to 2017 and were followed up at least one month.

Clinical features and outcomes of COVID-19 patients hospitalized for psychiatric disorders: a French multi-centered prospective observational study.

Background: Patients with psychiatric disorders are exposed to high risk of COVID-19 and increased mortality. In this study, we set out to assess the clinical features and outcomes of patients with current psychiatric disorders exposed to COVID-19.

Methods: This multi-center prospective study was conducted in 22 psychiatric wards dedicated to COVID-19 inpatients between 28 February and 30 May 2020.

Cognitive remediation and professional insertion of people with schizophrenia: RemedRehab, a randomized controlled trial.

Background: People suffering from schizophrenia cannot easily access employment in European countries. Different types of vocational programs coexist in France: supported employment, sheltered employment (ShE), and hybrid vocational programs. It is now acknowledged that the frequent cognitive impairments constitute a major obstacle to employment for people with schizophrenia.

Meningioangiomatosis: Multimodal Analysis and Insights From a Systematic Review.

Background: Meningioangiomatosis is a poorly studied, rare, benign, and epileptogenic brain lesion.

Objective: To demonstrate that surgical resection and a short-time interval to surgery improves epileptic seizure control, we performed a systematic review and meta-analysis of meningioangiomatosis cases.

Methods: Using PRISMA-IPD guidelines, the authors performed a systematic review and meta-analysis of histopathologically-proven meningioangiomatosis cases.

Molecular dynamics of the histamine H3 membrane receptor reveals different mechanisms of GPCR signal transduction.

In this work, we studied the mechanisms of classical activation and inactivation of signal transduction by the histamine H3 receptor, a 7-helix transmembrane bundle G-Protein Coupled Receptor through long-time-scale atomistic molecular dynamics simulations of the receptor embedded in a hydrated double layer of dipalmitoyl phosphatidyl choline, a zwitterionic polysaturated ordered lipid. Three systems were prepared: the apo receptor, representing the constitutively active receptor; and two holo-receptors-the receptor coupled to the antagonist/inverse agonist ciproxifan, representing the inactive state of the receptor, and the receptor coupled to the endogenous agonist histamine and representing the active state of the receptor. An extensive analysis of the simulation showed that the three states of H3R present significant structural and dynamical differences as well as a complex behavior given that the measured properties interact in multiple and interdependent ways.

Association Between Anxiety and New Organ Failure, Independently of Critical Illness Severity and Respiratory Status: A Prospective Multicentric Cohort Study.

Objectives: Anxiety results from the anticipation of a threat and might be associated with poor outcome in the critically ill. This study aims at showing that anxiety at admission in critically ill patients is associated with new organ failure over the first 7 days of ICU hospitalization independently of baseline organ failure at admission.

Design: Prospective multicenter cohort study.

Immune Activation and Deficit in Neurotransmitters Synthesis in Treatment Resistant Depression: About a Case of Hashimoto Encephalopathy.

We report a case of Hashimoto encephalopathy initially presented as a drug-resistant depression with predominant apathy and asthenia, successfully treated with cyclophosphamide. We suspected that the psychiatric symptoms were due to a deficit in neurotransmitter synthesis related to immune activation. We hypothesized that the immunomodulatory treatment helped to restore the neurotransmitter synthesis and thus decreased the patient's depressive symptoms.

An Interspecies Molecular and Functional Study of Organic Cation Transporters at the Blood-Brain Barrier: From Rodents to Humans.

Organic cation transporters (OCTs) participate in the handling of compounds in kidneys and at the synaptic cleft. Their role at the blood-brain barrier (BBB) in brain drug delivery is still unclear. The presence of OCT1,2,3 (SLC22A1-3) in mouse, rat and human isolated brain microvessels was investigated by either qRT-PCR, quantitative proteomics and/or functional studies.

Predictors of early postoperative epileptic seizures after awake surgery in supratentorial diffuse gliomas.

Objective: Functional-based resection under awake conditions had been associated with a nonnegligible rate of intraoperative and postoperative epileptic seizures. The authors assessed the incidence of intraoperative and early postoperative epileptic seizures after functional-based resection under awake conditions.

Methods: The authors prospectively assessed intraoperative and postoperative seizures (within 1 month) together with clinical, imaging, surgical, histopathological, and follow-up data for 202 consecutive diffuse glioma adult patients who underwent a functional-based resection under awake conditions.
