Generalizable and robust deep learning algorithm for atrial fibrillation diagnosis across geography, ages and sexes.

To drive health innovation that meets the needs of all and democratize healthcare, there is a need to assess the generalization performance of deep learning (DL) algorithms across various distribution shifts to ensure that these algorithms are robust. This retrospective study is, to the best of our knowledge, an original attempt to develop and assess the generalization performance of a DL model for AF events detection from long term beat-to-beat intervals across geography, ages and sexes. The new recurrent DL model, denoted ArNet2, is developed on a large retrospective dataset of 2,147 patients totaling 51,386 h obtained from continuous electrocardiogram (ECG).

Multiomic analysis of malignant pleural mesothelioma identifies molecular axes and specialized tumor profiles driving intertumor heterogeneity.

Malignant pleural mesothelioma (MPM) is an aggressive cancer with rising incidence and challenging clinical management. Through a large series of whole-genome sequencing data, integrated with transcriptomic and epigenomic data using multiomics factor analysis, we demonstrate that the current World Health Organization classification only accounts for up to 10% of interpatient molecular differences. Instead, the MESOMICS project paves the way for a morphomolecular classification of MPM based on four dimensions: ploidy, tumor cell morphology, adaptive immune response and CpG island methylator profile.

Preoperative flexion contracture does not affect outcome in total knee arthroplasty: A case-control study of 2,634 TKAs.

Background: One issue in total knee arthroplasty (TKA) is management of preoperative flexion contracture, which may be associated with poor functional outcome.

Aim: The aim of this study was to compare functional results in TKA with or without preoperative flexion contracture, treated according to a standardized algorithm of tissue release and bone cut.

Patients And Method: A single-center retrospective case-control study was performed on prospectively collected data for the period 1987-2016.

Longitudinal uric acid has nonlinear association with kidney failure and mortality in chronic kidney disease.

We investigated the shape of the relationship between longitudinal uric acid (UA) and the hazard of kidney failure and death in chronic kidney disease (CKD) patients, and attempted to identify thresholds associated with increased hazards. We included CKD stage 3-5 patients from the CKD-REIN cohort with one serum UA measurement at cohort entry. We used cause-specific multivariate Cox models including a spline function of current values of UA (cUA), estimated from a separate linear mixed model.

The Severity of Congenital Hypothyroidism With Gland-In-Situ Predicts Molecular Yield by Targeted Next-Generation Sequencing.

Introduction: Congenital hypothyroidism with gland-in-situ (CH-GIS) is usually attributed to mutations in the genes involved in thyroid hormone production. The diagnostic yield of targeted next-generation sequencing (NGS) varied widely between studies. We hypothesized that the molecular yield of targeted NGS would depend on the severity of CH.

Recency of Heart Failure Hospitalization, Outcomes, and the Effect of Empagliflozin: An EMPEROR-Pooled Analysis.

Background: Patients with a recent heart failure (HF) hospitalization have a high risk of rehospitalization and mortality. Early treatment may have a substantial impact on patient outcomes.

Objectives: This study sought to study the outcomes and effect of empagliflozin according to timing of prior HF hospitalization.

[Using simulation for assessment: the example of OSCE in medical students].

Training of health sciences students is based on the acquisition of clinical skills. Tools assessing the application of theoretical knowledge through written examinations or the tools evaluating student's performance at patient bedsides are characterized by a low reliability. The Objective Structured Clinical Examination (OSCE) was developed to address the lack of reliability and standardization of traditional forms of the assessment of clinical performance.

Multicenter randomized trial comparing diagnostic sensitivity and cellular abundance with aggressive versus standard biliary brushing for bile duct stenosis without mass syndrome.

BACKGROUND : The diagnosis of cholangiocarcinoma in patients with a biliary stricture without mass syndrome can be obtained by biliary brushing with a sensitivity of ~50 %. We performed a multicenter randomized crossover trial comparing the aggressive Infinity brush with the standard RX Cytology Brush. The aims were to compare sensitivity for cholangiocarcinoma diagnosis and cellularity obtained.

Comparison of three antithrombotic strategies for emergent carotid stenting during stroke thrombectomy: a multicenter study.

Background: Periprocedural antithrombotic treatment is a key determinant for the risk-benefit balance of emergent carotid artery stenting (eCAS) during stroke thrombectomy. We aimed to assess the safety and efficacy of three types of antithrombotic treatment.

Methods: Retrospective review of prospectively collected endovascular databases in four comprehensive stroke centers, including consecutive cases of eCAS for tandem lesion strokes between January 2019 and July 2021.

Preliminary Results of Bone Lengthening over Telescopic Titanium Intramedullary Rod.

Background: Limb lengthening and deformity correction in patients with abnormal bone associating fragility often require an approach combining methods of external and internal fixation. This study demonstrates results of simultaneous application of external fixator, and telescopic rod for femoral lengthening and deformity correction in three children with osteogenesis imperfecta or severe form of Ollier's disease.

Materials And Methods: Three patients (two boys with Ollier's disease and a girl with osteogenesis imperfecta, type I) were operated on for femoral lengthening with combined technique associating Ilizarov frame and titanium telescopic intramedullary rodding.

COVID-19 Vaccination and the Incidence of De Novo or Recurrent Rheumatoid Arthritis: A French and International (VigiBase) Signal Detection Study.

COVID-19 vaccination is critical in frequently immunocompromised patients with rheumatoid arthritis (RA). However, there is a question about the risk of RA flares following vaccination. Our study intended to find out about cases of new RA or flare-ups in people who already had RA that were reported in French and international pharmacovigilance databases after COVID-19 vaccination.

[The impact of specialized management on allergic asthma outcomes].

Introduction: Allergic asthma has variable characteristics depending on the region of occurrence. Management is often organized without easy access to a specialized pneumo-allergological evaluation.

Objectives: PRIMARY: To characterize allergic asthma in patients followed at the Nancy University Hospital.

Dosimetric predictive factors for facial nerve paralysis after cyberknife® stereotactic radiotherapy for vestibular schwannomas: A single institution experience of 88 patients.

Improving representativeness in trials: a call to action from the Global Cardiovascular Clinical Trialists Forum.

Participants enrolled in cardiovascular disease (CVD) randomized controlled trials are not often representative of the population living with the disease. Older adults, children, women, Black, Indigenous and People of Color, and people living in low- and middle-income countries are typically under-enrolled in trials relative to disease distribution. Treatment effect estimates of CVD therapies have been largely derived from trial evidence generated in White men without complex comorbidities, limiting the generalizability of evidence.

Outcomes after endovascular mechanical thrombectomy for low compared to high National Institutes of Health Stroke Scale (NIHSS): A multicenter study.

Objective: The role of endovascular mechanical thrombectomy (MT) in patients presenting with "minor" stroke is uncertain. We aimed to compare outcomes after MT for ischemic stroke patients presenting with National Institutes of Health Stroke Scale (NIHSS) 5 and - within the low NIHSS cohort - identify predictors of a favorable outcome, mortality, and symptomatic intracranial hemorrhage (ICH).

Methods: We retrospectively analyzed a prospectively maintained, international, multicenter database.

Unattended home sleep studies for the diagnosis of obstructive sleep apnea in a population of French children.

Background: Ambulatory exams were preferred in children during the COVID-19 pandemic. Polysomnography (PSG), the gold standard for obstructive sleep apnea (OSA) diagnosis, requires several leads and sensors to be attached to the child's body. Children are more comfortable with respiratory polygraphic (RP) recording, which needs fewer sensors.

Implementing the Point Spread Function Deconvolution for Better Molecular Characterization of Newly Diagnosed Gliomas: A Dynamic F-FDOPA PET Radiomics Study.
