Clinical significance of stratifying prostate cancer patients through specific circulating genes.

Patient stratification remains a challenge for optimal treatment of prostate cancer (PCa). This clinical heterogeneity implies intra-tumoural heterogeneity, with different prostate epithelial cell subtypes not all targeted by current treatments. We reported that such cell subtypes are traceable in liquid biopsies through representative transcripts.

Data-driven cluster analysis identifies distinct types of metabolic dysfunction-associated steatotic liver disease.

Metabolic dysfunction-associated steatotic liver disease (MASLD) exhibits considerable variability in clinical outcomes. Identifying specific phenotypic profiles within MASLD is essential for developing targeted therapeutic strategies. Here we investigated the heterogeneity of MASLD using partitioning around medoids clustering based on six simple clinical variables in a cohort of 1,389 individuals living with obesity.

Postoperative lymphopaenia as a risk factor for postoperative infections in cancer surgery: A prospective multicentre cohort study (the EVALYMPH study).

Background: Stress due to surgical trauma decreases postoperative lymphocyte counts (LCs), potentially favouring the occurrence of postoperative infections (PIs).

Objectives: We aimed to determine whether postoperative lymphopaenia following thoracic or gastrointestinal cancer surgery is an independent risk factor for PIs and to identify modifiable factors related to anaesthesia and surgical procedures that might affect its occurrence.

Study Design: The EVALYMPH study was a prospective, multicentre cohort study with a 30-day patient follow-up.

Academic impact of French Hip & Knee Surgery Society (SFHG): A bibliometric analysis.

Introduction: The French Hip & Knee Surgery Society (SFHG) brings together French-speaking hip and knee expert surgeons. There has been an exponential growth of orthopaedic surgical activity over the last decade and hip and knee surgery clinical research has had a similar growth. Despite this, the SFHG's contribution to the orthopaedic literature remains poorly known.

To assess a region-of-interest-based machine-learning algorithm aimed at characterising GG ≥2 prostate cancer on multiparametric MRI.

Efficacy and safety of one anastomosis gastric bypass versus Roux-en-Y gastric bypass at 5 years (YOMEGA): a prospective, open-label, non-inferiority, randomised extension study.

Background: The multicentre randomised trial YOMEGA (NCT02139813) comparing the one anastomosis gastric bypass (OAGB) with the Roux-en-Y gastric bypass (RYGB) confirmed the non-inferiority of OAGB on weight loss outcomes at 24 months. We aimed to report weight loss, metabolic, and safety outcomes at 5 years.

Methods: YOMEGA is a prospective, open-label, non-inferiority, randomised trial conducted at nine centres in France.

Fosfomycin-induced agranulocytosis: a case report and review of the literature.

Background: The intravenous form of fosfomycin, a bactericide antibiotic used to treat multiresistant bacterial infections is little prescribed. The most common reported adverse effects are hypokaliemia and hypernatremia. We describe a case of agranulocytosis, a rarely described side effect that may be fatal.

Integrating Echocardiography Parameters With Explainable Artificial Intelligence for Data-Driven Clustering of Primary Mitral Regurgitation Phenotypes.

Background: Primary mitral regurgitation (MR) is a heterogeneous clinical disease requiring integration of echocardiographic parameters using guideline-driven recommendations to identify severe disease.

Objectives: The purpose of this preliminary study was to explore novel data-driven approaches to delineate phenotypes of MR severity that benefit from surgery.

Methods: The authors used unsupervised and supervised machine learning and explainable artificial intelligence (AI) to integrate 24 echocardiographic parameters in 400 primary MR subjects from France (n = 243; development cohort) and Canada (n = 157; validation cohort) followed up during a median time of 3.

Quantification of primary mitral regurgitation by echocardiography: A practical appraisal.

The accurate quantification of primary mitral regurgitation (MR) and its consequences on cardiac remodeling is of paramount importance to determine the best timing for surgery in these patients. The recommended echocardiographic grading of primary MR severity relies on an integrated multiparametric approach. It is expected that the large number of echocardiographic parameters collected would offer the possibility to check the measured values regarding their congruence in order to conclude reliably on MR severity.

Clinical significance of myocardial contraction fraction in significant primary mitral regurgitation.

Background: The optimal timing for mitral valve (MV) surgery in asymptomatic patients with primary mitral regurgitation (MR) remains a matter of debate. Myocardial contraction fraction (MCF) - the ratio of the left ventricular (LV) stroke volume to that of the myocardial volume - is a volumetric measure of LV myocardial shortening independent of size or geometry.

Aim: To assess the relationship between MCF and outcome in patients with significant chronic primary MR due to prolapse managed in contemporary practice.

Reasons for delays to orthopaedic and trauma surgery: A retrospective five-year cohort.

Background: Early surgery seeks to decrease peri-operative complication rates and mean hospital stay lengths while also improving patient satisfaction. Few data exist on optimising care before orthopaedic and trauma surgery (OTS), notably regarding delays to surgery after admission. The objective of this study was to identify reasons for OTS delays at a university-hospital OTS centre in France.

Orthopaedic and trauma surgery in France: Do patterns differ across healthcare institution types (public community, public university, private not-for-profit, and private for-profit)?

Background: No studies have evaluated, to our knowledge, potential differences in practices in France according to type of healthcare institution, i.e., university public hospital, community public hospital, or private hospital with or without participation in the public healthcare system.

Button Battery Ingestion in Children (PilBouTox®): A Prospective Study Describing the Clinical Course and Identifying Factors Related to Esophageal Impaction or Severe Cases.

In this study, we aimed to identify the factors related to esophageal impaction following button battery (BB) ingestion in children. PilBouTox, a prospective multicentric observational cohort study, was conducted from French Poison Control Centers between June 1, 2016 and May 31, 2018. Children (0-12 years old) with BB ingestion were included.

Post-discharge and long-term follow-up after an acute coronary syndrome: International Collaborative Group of CNCF position paper.

Introduction: Long-term follow-up after an acute coronary syndrome (ACS) presents a crucial challenge due to the high residual cardiovascular risk and the potential for major bleeding events. Although several treatment strategies are available, this article focuses on patients who have undergone percutaneous coronary intervention (PCI) for ACS, which is a frequent clinical situation. This position paper aims to support physicians in daily practice to improve the management of ACS patients.

Significance of Left Ventricular Ejection Time in Primary Mitral Regurgitation.

The optimal timing for mitral valve (MV) surgery in asymptomatic patients with primary mitral regurgitation (MR) remains controversial. We aimed at evaluating the relation between left ventricular ejection time (LVET) and outcome in patients with moderate or severe chronic primary MR because of prolapse. Clinical, Doppler echocardiographic, and outcome data prospectively collected from 302 patients (median age 61 [54 to 74] years, 34% women) with moderate or severe primary MR were analyzed.

Knockout in U251 Glioblastoma Cells Reduces Tumor Sphere Formation by Increasing Oxidative Stress and Suppressing Methionine Dependency.

Previously, the in vitro growth of cancer stem cells in the form of tumor spheres from five different brain cancer cell lines was found to be methionine-dependent. As this earlier work indicated that , a folate-dependent mitochondria aldehyde dehydrogenase gene, is upregulated in glioblastoma stem cells, we invalidated this gene using CRISPR-cas 9 technique in this present work. We reported here that this invalidation was effective in U251 glioblastoma cells, and no cas9 off target site could be detected by genome sequencing of the two independent knockout targeting either exon I or exon III.

Identifying early indicators of secondary peritonitis in critically ill patients with cirrhosis.

Ascitic fluid infection (AFI) is a life-threatening complication of cirrhosis. We aimed to identify early indicators of secondary peritonitis (SP), which requires emergency surgery, and to describe the outcomes of SP and spontaneous bacterial/fungal peritonitis (SBFP). Adults with cirrhosis and AFI admitted to 16 university or university-affiliated ICUs in France between 2002 and 2017 were studied retrospectively.

French Hip & Knee Society classification of short-stem hip prostheses: Inter- and intra-observer reproducibility.

Introduction: In total hip replacement (THR), a short stem theoretically provides more physiological force transfer to the proximal femur, conserves bone stock and facilitates minimally invasive surgery. On the other hand, such implants involve a learning curve and incur risk of malpositioning or fracture and of secondary mobilization. There are several types of short stem, and classification is needed.

Hemodynamic Profiles of Cardiogenic Shock Depending on Their Etiology.

The pathophysiology of cardiogenic shock (CS) varies depending on its etiology, which may lead to different hemodynamic profiles (HP) and may help tailor therapy. We aimed to assess the HP of CS patients according to their etiologies of acute myocardial infarction (AMI) and acute decompensated chronic heart failure (ADCHF). We included patients admitted for CS secondary to ADCHF and AMI.

Characterization and Treatment of SARS-CoV-2 in Nasal and Bronchial Human Airway Epithelia.

In the current COVID-19 pandemic effective treatments represents a major challenge. However, the scarcity of biologically relevant pre-clinical models of SARS-CoV-2 infection imposes a significant barrier for scientific and medical progress, including the rapid transition of potentially effective treatments to the clinical setting. We use reconstituted human airway epithelia to isolate and then characterize the viral infection kinetics, tissue-level remodeling of the cellular ultrastructure, and transcriptional early immune signatures induced by SARS-CoV-2 in a physiologically relevant model.

Predictors of Outcomes Following Transcatheter Edge-to-Edge Mitral Valve Repair.

Transcatheter edge-to-edge mitral valve repair is a viable alternative to surgery in patients with severe mitral regurgitation and high surgical risk. Yet the specific group of patients who would optimally benefit from this therapy remains to be determined. Selection of patients for transcatheter strategy is currently based on surgical prognostic scores and technical feasibility.
