Background: Routine preprocedural fasting before cardiac catheterization remains common practice, despite a lack of robust evidence to support this practice. We investigated the impact of a liberal nonfasting strategy vs a standardized nil per os (NPO) regimen prior to cardiac catheterization.

Methods: Adult inpatients undergoing elective or urgent cardiac catheterization were randomized (1:1 ratio) to either NPO past midnight or ad libitum intake of liquids and solids (without dietary constraints) until immediately prior to the procedure.

Aims: To examine the association of a remote monitoring programme (RMP) with all-cause mortality and hospital admissions for heart failure (HF) within the French healthcare system.

Methods And Results: A national-scale, real-world, propensity-weighted cohort study was conducted using the SNDS French database from August 2018 to December 2022 (NCT06312501). Patients receiving standard of care (SoC) were compared with those receiving RMP (Satelia® Cardio, NP Medical).

Genome-wide association study unravels mechanisms of brain glymphatic activity.

Nat Commun

January 2025

Department of Neurology and National Center for Neurological Disorders, Huashan Hospital, State Key Laboratory of Medical Neurobiology and MOE Frontiers Center for Brain Science, Shanghai Medical College, Fudan University, Shanghai, China.

Brain glymphatic activity, as indicated by diffusion-tensor imaging analysis along the perivascular space (ALPS) index, is involved in developmental neuropsychiatric and neurodegenerative diseases, but its genetic architecture is poorly understood. Here, we identified 17 unique genome-wide significant loci and 161 candidate genes linked to the ALPS-indexes in a discovery sample of 31,021 individuals from the UK Biobank. Seven loci were replicated in two independent datasets.

Background: Detection of atrial tachyarrhythmias (ATA) on long-term electrocardiogram (ECG) recordings is a prerequisite to reduce ATA-related adverse events. However, the burden of editing massive ECG data is not sustainable. Deep learning (DL) algorithms provide improved performances on resting ECG databases.

Purpose: Harmonizing variables for constructs measured differently across studies is essential for comparing, combining, and generalizing results. We developed and fielded a brief survey to harmonize Likert and continuous versions of measures for two constructs, self-rated health and self-rated memory, for use in studies of French older adults.

Methods: We recruited 300 participants from a French memory clinic in 2023 to answer both the Likert and continuous versions of self-rated health and self-rated memory questions.

Untargeted LC-HRMS analyses reveal metabolomic specificities between wine yeast strains selected for their malic acid production.

BIOLAFFORT, 11 rue Aristide Berges, 33270 Floirac, France; UMR OENO, Université de Bordeaux, INRAE, INP, BSA, ISVV, 210 Chemin de Leysotte, 33882 Villenave d'Ornon, France. Electronic address:

The alcoholic fermentation of wine is mostly achieved by the species Saccharomyces cerevisiae that display a large variability for their ability to consume or produce malic acid. To better characterize the metabolism of such group of strains we explored their non-volatile metabolome using an untargeted LC-HRMS approach. The chemical classes and the putative structures of several hundred compounds where annotated using MS2 spectra using the SIRIUS software.

Background: Aarskog-Scott syndrome (AAS) is a rare condition with multiple congenital anomalies, caused by hemizygote variants in the gene. Its description was based mostly on old case reports, in whom a molecular diagnosis was not always available, or on small series. The aim of this study was to better delineate the phenotype and the natural history of AAS and to provide clues for the diagnosis and the management of the patients.

Emergence and tunability of Fermi-pocket and electronic instabilities in layered Nickelates.

J Phys Condens Matter

January 2025

CNRS, LOMA, UMR 5798, Université de Bordeaux, 351 Cr de la Libération, Talence, Nouvelle-Aquitaine, 33400, FRANCE.

Layered Nickelates have gained intensive attention as potential high-temperature superconductors, showing similarities and subtle differences to well-known Cuprates. This study introduces a modelling framework to analyze the tunability of electronic structures by focusing on effective orbitals and additional Fermi pockets, mimicking doping or external pressure qualitatively. It investigates the role of the $3d_{z^2}$ orbital in interlayer hybridization, which leads to the formation of a second pocket in the Fermi surface.

Amphiphilic dynamic covalent polymer vectors of siRNA.

Chem Sci

Institut des Biomolécules Max Mousseron (IBMM), Université de Montpellier, CNRS, ENSCM Montpellier France

Dynamic covalent polymers (DCPs) recently emerged as smart siRNA delivery vectors, which dynamically self-assemble through siRNA templating and depolymerize in a controlled manner. Herein, we report the dynamic combinatorial screening of cationic and amphiphilic peptide-based monomers. We provide experimental evidence, by mass spectrometry analyses, of the siRNA-templated formation of DCPs, and show that amphiphilic DCPs display superior activity in terms of siRNA complexation and delivery in cells.

Background And Aim: Cannabis use disorder (CUD) is strongly influenced by genetic factors; however the mechanisms underpinning this association are not well understood. This study investigated whether a polygenic risk score (PRS) based on a genome-wide association study for CUD in adults predicts cannabis use in adolescents and whether the association can be explained by inter-individual variation in structural properties of brain white matter or risk-taking behaviors.

Design And Setting: Longitudinal and cross-sectional analyses using data from the IMAGEN cohort, a European longitudinal study integrating genetic, neuroimaging and behavioral measures.

Introduction: Several cardiovascular outcome trials have been conducted to assess the cardiovascular safety and efficacy of glucagon-like peptide-1 receptor agonists (GLP1-RAs) on cardiorenal outcomes in patients with type-2 diabetes (T2D). However, the strict requirements of randomised controlled trials to avoid most confounding factors are at the expense of external validity. Using national real-world data, we aimed to evaluate the effectiveness of GLP-1RAs in association with metformin especially on cardiovascular events, hospitalisation for heart failure and all-cause death in comparison with other diabetes treatment schemes using dipeptidyl peptidase IV inhibitors, sulfonylureas/glinides or insulin also associated with metformin.

Background: : With more than 60 million new cases around the world each year, traumatic brain injury (TBI) causes substantial mortality and morbidity. Managing TBI is a major human, social, and economic concern. In the last 20 years, there has been an increase in clinical trials in neurocritical care, leading mostly to negative results.

Major role of dolutegravir in the emergence of the S147G integrase resistance mutation.

J Antimicrob Chemother

December 2024

Department of Virology, Sorbonne Université, INSERM, UMR-S 1136, Institut Pierre Louis d'Epidémiologie et de Santé Publique, AP-HP, Hôpitaux Universitaires Pitié Salpêtrière - Charles Foix, 83 Boulevard de l'Hôpital 39, F-75013 Paris, France.

Background: The S147G mutation is associated with high-level resistance to the integrase strand transfer inhibitor (INSTI) elvitegravir. In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

Association between urate-lowering therapy and kidney failure in patients with chronic kidney disease.

J Nephrol

January 2025

Pharmacoepidemiology Unit, Department of Clinical Pharmacology, Amiens-Picardie University Medical Center, CHU Amiens-Picardie, Rond-Point du Professeur Christian Cabrol, 80054, Amiens Cedex, France.

Background: Hyperuricemia is a hallmark of gout and a suspected risk factor for the progression of chronic kidney disease (CKD). However, the impact of urate-lowering therapy on CKD progression is subject to debate. The objective of the present study was to describe the prevalence of inappropriate urate-lowering therapy prescriptions and evaluate the association between urate-lowering therapy prescription and the progression of kidney disease in patients with CKD.
