Association between education level and access to disease-modifying treatment in patients with multiple sclerosis in France.

Background: We hypothesized that differences in access to disease-modifying treatments (DMTs) could explain the association between socioeconomic status and disability progression in multiple sclerosis (MS).

Objective: This study aimed to analyze the association between education level and DMT use in France.

Methods: All patients from OFSEP network with MS onset over 1996-2014 and aged ⩾ 25 years at onset were included.

Evaluating the added-value of video recording in respiratory polygraphy for the diagnosis of obstructive sleep apnea in children.

Polysomnography (PSG) is the gold standard for diagnosing obstructive sleep apnea (OSA) in children but not always available. Abbreviated exams exist, such as respiratory polygraphy (RP), but are less accurate for OSA diagnosis. Video recording (video-RP) may provide a more precise estimation of the total sleep time (TST) compared to RP alone.

Association between education level and disability progression in patients with multiple sclerosis in France.

Background: Studies have reported an association between socioeconomic status and disability progression in multiple sclerosis (MS), but findings using the pre-MS individual socioeconomic status are missing.

Objective: The objective was to investigate the association between education level and disability progression.

Methods: All Observatoire Français de la Sclérose en Plaques (OFSEP) patients with MS clinical onset over 1960-2014, and aged ⩾25 years at MS onset were included.

Mirror writing of digits: Is there a difference between boys and girls?

The neurological process of mirror generalization in memory, also known as mirror symmetrization, presents a real dilemma for typically developing 5- to 6-year-olds when learning to write characters (digits and letters). Should they write the digit 3 oriented to the left, that is correctly, or to the right, which leads to its mirror image ε? It has been anecdotally suggested that boys are more prone to mirror-writing than girls, but there is no scientific evidence for this idea. The present article gathers data from 691 children in the upper section of the French école maternelle (age between 5 and 6 ½), who each wrote the digits 0 to 9 four times under dictation and not necessarily in their natural order.

Endovascular therapy versus medical management in isolated anterior cerebral artery acute ischemic stroke: a multinational multicenter propensity score-weighted study.

Background: Isolated anterior cerebral artery occlusions (ACAo) in patients with acute ischemic stroke present significant challenges due to their rarity. The efficacy and safety of endovascular therapy (EVT) in comparison with best medical therapy (BMT) for ACAo remains unclear. This study aimed to assess the outcomes of these treatments.

"UDE DIATOMS in the Wild 2024": a new image dataset of freshwater diatoms for training deep learning models.

Background: Diatoms are microalgae with finely ornamented microscopic silica shells. Their taxonomic identification by light microscopy is routinely used as part of community ecological research as well as ecological status assessment of aquatic ecosystems, and a need for digitalization of these methods has long been recognized. Alongside their high taxonomic and morphological diversity, several other factors make diatoms highly challenging for deep learning-based identification using light microscopy images.

Mineralocorticoid Receptor and Sleep Quality in Chronic Kidney Disease.

The classical function of the mineralocorticoid receptor (MR) is to maintain electrolytic homeostasis and control extracellular volume and blood pressure. The MR is expressed in the central nervous system (CNS) and is involved in the regulation of the hypothalamic-pituitary-adrenal (HPA) axis as well as sleep physiology, playing a role in the non-rapid eye movement (NREM) phase of sleep. Some patients with psychiatric disorders have very poor sleep quality, and a relationship between MR dysregulation and this disorder has been found in them.

Modulating the Iron Microenvironment for a Cooperative Interplay Between Fe-N-C Single Atoms and FeC Nanoclusters on the Oxygen Reduction Reaction.

The coexistence of single atoms and nanoparticles is shown to increase the oxygen reduction performance in Fe-N-C electrocatalysts, but the mechanisms underlying this synergistic effect remain elusive. In this study, model Fe-N-C electrocatalysts with controlled ratios of FeN sites and FeC nanoclusters is systematically designed and synthesized. Experiments and density functional theory (DFT) computations reveal that FeC nanoclusters near FeN sites modulate the electron density of the Fe single-atom microenvironment through an electron withdrawing effect.

Streptolysin O accelerates the conversion of plasminogen to plasmin.

Group A Streptococcus (GAS) is a human-specific bacterial pathogen that can exploit the plasminogen-plasmin fibrinolysis system to dismantle blood clots and facilitate its spread and survival within the human host. In this study, we use affinity-enrichment mass spectrometry to decipher the host-pathogen protein-protein interaction between plasminogen and streptolysin O, a key cytolytic toxin produced by GAS. This interaction accelerates the conversion of plasminogen to plasmin by both the host tissue-type plasminogen activator and streptokinase, a bacterial plasminogen activator secreted by GAS.

Perioperative severity of acute appendicitis during the confinement related to SARS COVID-19: a retrospective comparative cohort.

Objective: To evaluate the perioperative severity of acute appendicitis during the COVID-19 pandemic compared to the same periods in 2018 and 2019 in the Nancy-Metz region, France. Acute appendicitis is a common surgical emergency that can lead to severe complications if not treated promptly. The COVID-19 pandemic and subsequent lockdowns resulted in reduced hospital visits, potentially delaying treatment for appendicitis and increasing perioperative severity.

A light-driven ultrafast sensor based on biocompatible solvatochromic metal-organic frameworks.

The design of fast, endurant, and biocompatible porous frameworks with solvatochromism, aimed to addressing the multiple visual sensing of chemicals, still remains a challenge. Here, we report on a solvatochromic metal-organic framework (MOF) based on cobalt and trimesic acid. We examined its solvatochromism through the solvent exchange and revealed high selectivity to water/dimethylformamide combination.

Mineralocorticoid Receptor Antagonists in Heart Failure: An Update.

Spironolactone, a steroidal mineralocorticoid receptor antagonist (MRA), has been used to treat patients with heart failure (HF) for more than half a century. Spironolactone improved outcomes in patients with severely symptomatic HF with reduced ejection fraction, and later, eplerenone expanded the benefits to patients with mildly symptomatic HF with reduced ejection fraction and myocardial infarction complicated by HF. Spironolactone reduced HF events in some patients with HF with preserved ejection fraction, but the results were not generalizable to all patients with HF with preserved ejection fraction.

Differential bioconcentration and sensitivity of Dreissena polymorpha and Dreissena rostriformis bugensis to the antidepressant sertraline.

Sertraline is one of the most widely prescribed antidepressants, worldwide detected in rivers, thus raising concern about its ecotoxicology. However, there is knowledge gap on its pharmacokinetics and pharmacodynamics in freshwater bivalves. Comparative biology can help to gain in understanding and improve our ability to assess ecotoxicological risks in a wide range of species.

Case report: A laser and radiofrequency ablation in a laryngeal chondrosarcoma.

Introduction And Importance: Chondrosarcoma is a tumor which arises from cartilage, and whose apparition can occur in any site. However, it remains rare in the larynx. Management depends on the grade and the stage of the tumor at the time of the presentation.

Customizable patterned membranes for cardiac tissue engineering: A model-assisted design method.

Myocardial infarction can cause irreversible damage to the heart muscle, which can lead to heart failure. The difficulty of the treatment mainly arises from the anisotropic behavior of the myocardium fibrous structure. Patches or cardiac restraint devices appear to be a promising approach to post-infarction treatment.

Measurement of Cumulative Drug Exposure from Clinical Data Warehouse.

Polypharmacy (PP) and hyperpolypharmacy (HPP), are prevalent among cancer patients and are associated with an increased risk of drug-drug interactions (DDI) and potentially inappropriate medications (PIM). This study aimed to characterize PP, HPP, DDI, and PIM in patients with hematological malignancies hospitalized for hematopoietic stem cell transplantation (HSCT) by introducing a novel metric: cumulative drug exposure. Clinical data warehouse (CDW) records were employed to develop algorithms that quantified patients' cumulative exposure to these prescribing determinants during hospitalization.

Catalytic mechanism underlying the regiospecificity of coumarin-substrate transmembrane prenyltransferases in Apiaceae.

Plant membrane-bound prenyltransferases (PTs) catalyse the transfer of prenyl groups to acceptor substrates, phenols, using prenyl diphosphates as the donor substrate. The presence of prenyl residues in the reaction products, prenylated phenols, is key to the expression of a variety of physiological activities. Plant PTs generally exhibit high specificities for both substrate recognition and prenylation sites, while the molecular mechanism involved in these enzymatic properties is largely unknown.
