Priors and decision thresholds in phase 2 and phase 3 randomized controlled trials evaluating drug efficacy using Bayesian methods: a systematic review.

Objective: To describe the priors and decision thresholds in phase 2 and 3 RCTs evaluating drug efficacy using Bayesian methods.

Study Design And Setting: A systematic review of phase 2 and 3 RCTs evaluating drug efficacy through Bayesian inference was conducted across the MEDLINE, EMBASE and Cochrane databases, with no date restrictions until September 2022. The type of prior used for the analysis of the primary endpoint and its characteristics (type and parameters of the distribution, justification, sensitivity analysis), the use of a posterior probability decision threshold defined a priori, and its value, were extracted.

Long-Term Clinical and Biological Prognostic Factors of Anti-NMDA Receptor Encephalitis in Children.

Background And Objectives: Anti-NMDAR encephalitis (NMDARE) is a severe neurologic condition, and recently, the NMDAR Encephalitis One-Year Functional Status (NEOS) score has emerged as a 1-year prognostic tool. This study aimed to evaluate NEOS score and biomarker (neurofilament light chains [NfL], total-Tau protein, glial fibrillary acidic protein, and serum cytokines) correlation with modified Rankin Scale (mRS), cognitive impairment, and clinical recovery in pediatric NMDARE over 2 years.

Methods: In this French multicenter observational study, 104 pediatric patients with NMDARE were followed for a minimum of 2 years.

What is the lower limb length discrepancy after arthroplasty for proximal femoral fracture? A prospective, multicenter observational study of 590 hips.

Introduction: Lower limb length discrepancy (LLD) following hip arthroplasty after proximal femoral fracture (PFFA) is little studied. The aim of this work was to answer the following questions: 1) What are the incidence and mean values ​​of LLD after PFFA? 2) What are the clinical consequences (tolerance) of LLD after PFFA? 3) Can we identify risk factors for LLD after PFFA? 4) Is there a significant difference in terms of LLD after PFFA to treat intra- versus extra-capsular fractures?

Hypothesis: LLD after proximal femoral fracture arthroplasty is rare but has good clinical tolerance, given the low functional demands of the patients.

Patients And Methods: This is a multicenter prospective observational cohort study (15 centers), including 590 patients, operated on for hip arthroplasty for proximal femur fracture between May 2022 and June 2023.

Spinal muscular atrophy is also a disorder of spermatogenesis.

Background: Spinal muscular atrophy (SMA) patients benefit from pre-mRNA splicing modifiers targeting the SMN2 gene, which aims to increase functional SMN production. The animal toxicity affecting spermatogenesis associated with one such treatment raised questions about male SMA patients' spermatogenesis.

Methods: This descriptive, cross-sectional study was conducted from June 2022 to July 2023.

Objective: This study aims to present and analyze the results of the French cohort in a European Board of Ophthalmology (EBO) survey on cataract surgical training in Europe, highlighting the particularities of French training.

Materials And Methods: A 23-question electronic questionnaire was sent to interns applying for the EBO examination from 2018 to 2022. Responses from French participants were specifically collected and analyzed.

Efficacy of convalescent plasma for the treatment of COVID-19 in lung transplant recipients: A multicenter French study.

Introduction: Lung transplant (LT) recipients are at greater risk of complications from COVID-19. Treatment options are limited partly due to interactions with immunosuppressive agents. Convalescent plasma (CP) is a potential treatment option, but it has not been extensively studied in LT patients.

Real-world multicentre study of cefiderocol treatment of immunocompromised patients with infections caused by multidrug-resistant Gram-negative bacteria: CEFI-ID.

Introduction: The increase in the population of immunocompromised patients due to advances in management of end-stage diseases and transplants poses challenges in treating infections caused by multi-drug resistant (MDR) pathogens. Cefiderocol (FDC), a siderophore cephalosporin, has shown efficacy against carbapenem-resistant Gram-negative bacteria.

Methods: This retrospective multicentre study investigated the real-world use of FDC in 114 immunocompromised adults treated for MDR infections in 12 French hospitals (June 2020-November 2023).

Acute kidney injury as a key predictor of cardiovascular events in chronic kidney disease patients: the CKD-REIN study.

Background And Hypothesis: Cardiovascular diseases are a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). Acute kidney injury (AKI) has been increasingly recognized as a potential exacerbating factor for cardiovascular events in these patients. The CKD-REIN study aims to explore the relationship between AKI and the risk of major adverse cardiovascular events (MACE) in a cohort of CKD patients.

Vasodilator drugs and heart-related outcomes in systemic sclerosis: an exploratory analysis.

Background And Aims: Systemic sclerosis (SSc) is an autoimmune connective disease characterised by excessive extracellular matrix deposition and widespread skin and internal organ fibrosis including various cardiac manifestations. Heart involvement is one of the leading causes of death among patients with SSc. In this study, we aimed to assess the effect of various vasodilator treatments.

MRI management of NMOSD and MOGAD: Proposals from the French Expert Group NOMADMUS.

Background: Currently, there are no available recommendations or guidelines on how to perform MRI monitoring in the management of neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). The issue is to determine a valuable MRI monitoring protocol to be applied in the management of NMOSD and MOGAD, as previously proposed for the monitoring of multiple sclerosis.

Objectives: The objectives of this work are to establish proposals for a standardized and feasible MRI acquisition protocol, and to propose control time points for systematic MRI monitoring in the management of NMOSD and MOGAD.

Prognostic factors for patients with cancer-associated dermatomyositis: a retrospective, multicenter cohort study of 73 patients.

Objectives: To investigate factors associated with dermatomyositis (DM) complete clinical response and overall survival with a focus on the use of immunosuppressive therapies in patients with cancer-associated DM.

Methods: We performed a multicentre, retrospective cohort study. Multivariable survival analyses used a Cox model with time-dependent covariates and adjustments with inverse probability censoring weighting.

Laboratory practices for the diagnosis and management of mucormycosis in France, 2024.

This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

Factors associated with severity and mortality of COVID-19 in patients with connective tissue diseases and rheumatoid arthritis: A nation-wide, population-based analysis of the French national medico-administrative SNDS database.

Objectives: To investigate the risk and predictors of severity and mortality of COVID-19 infection in patients with Connective Tissue Diseases (CTDs).

Methods: Using the French nationwide claims and hospitalization database, we assembled a nation-wide exhaustive cohort of adult CTD patients with rheumatoid arthritis, systemic lupus, Sjögren's disease, inflammatory myopathies, systemic sclerosis. We analyzed the rates of hospitalization, severe inpatient stays (intensive care unit [ICU] admissions or in-hospital mortality), and in-hospital mortality with COVID-19 from January 1st to December 31st, 2020.

Epidermal maintenance of Langerhans cells relies on autophagy-regulated lipid metabolism.

Macroautophagy (often-named autophagy), a catabolic process involving autophagy-related (Atg) genes, prevents the accumulation of harmful cytoplasmic components and mobilizes energy reserves in long-lived and self-renewing cells. Autophagy deficiency affects antigen presentation in conventional dendritic cells (DCs) without impacting their survival. However, previous studies did not address epidermal Langerhans cells (LCs).

[Evaluate the host cellular immune response to better prevent and diagnose viral infections].

In medicine, virological diagnosis is mainly based on the detection of the viral genome and antigens, or on the identification of specific antibodies produced in response to infection. These strategies are suitable for characterizing an active infection or past contact with an already known virus. The recent development of tests for evaluating the host's cellular immune response opens new perspectives for personalized patient care based on immunomonitoring.

SEPSIGN: early identification of sepsis signs in emergency department.

Because 20-30% of patients with sepsis deteriorate to critical illness, biomarkers that provide accurate early prognosis may identify which patients need more intensive treatment versus safe early discharge. The objective was to test the performance of sVEGFR2, suPAR and PCT, alone or combined with clinical signs and symptoms, for the prediction of clinical deterioration. This prospective observational study enrolled patients with suspected infection who met SIRS criteria without organ dysfunction (delta SOFA <2 from baseline) from 16 emergency departments.
