Disease-modifying treatment and disability progression in subclasses of patients with primary progressive MS: results from the Big MS Data Network.

Background: Effectiveness of disease-modifying treatment (DMT) in people affected by primary progressive multiple sclerosis (PPMS) is limited. Whether specific subgroups may benefit more from DMT in a real-world setting remains unclear. Our aim was to investigate the potential effect of DMT on disability worsening among patients with PPMS stratified by different disability trajectories.

Endoscopic papillectomy versus surgical ampullectomy for adenomas and early cancers of the papilla: a retrospective Pancreas2000/European Pancreatic Club analysis.

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.

Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.

TWEAK and TNFɑ Pro-inflammatory Soluble Cytokines and their Specific Autoantibodies Secretion in Multiple Sclerosis Patients.

Multiple sclerosis (MS) is a complex, chronic inflammatory disease of the central nervous system, where immune dysregulation plays a critical role. We sought to explore the modulation of the pro-inflammatory cytokines tumor necrosis factor-alpha (TNFɑ) and TNF-like weak inducer of apoptosis (TWEAK), along with their respective autoantibodies, TNAb and TWAb, and to decipher potential associations between these and clinical characteristics which could assist personalized therapy in MS. We also assessed the complementarity to leading candidate biomarkers in MS patient monitoring, namely, glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL).

Current evidence gaps to support systematic cytomegalovirus screening in pregnancy.

The benefits of screening for cytomegalovirus (CMV) infection during pregnancy remain a topic of debate. To date, no randomized trial has compared the impact of screening versus routine management on the prevention of severe sequelae in newborns. Furthermore, it is unclear what actions can be taken in case of a positive screening given that there is limited evidence of effective interventions as no treatments showed significant effect on the frequency of congenital cytomegalovirus infections and, as additional challenge, the window for effective treatment initiation after maternal infection is narrow, estimated to be as short as five weeks.

CCDC69 maintains genome integrity by regulating KIF2C/MCAK depolymerase activity and the stability of the chromosomal passenger complex.

Accurate genome inheritance during cell division relies on a complex chromosome segregation mechanism. This process occurs once all the kinetochores of sister chromatids are attached to microtubules emanating from the opposite poles of the mitotic spindle. To control the precision of this mechanism, the Chromosome Passenger Complex (CPC) actively identifies and corrects improper microtubule attachments.

The role of acoustic telemetry in assessing fish connectivity within marine seascapes: A global review.

The study of aquatic animal movements is a rapidly growing field of research, with tracking methodology ever developing and refining. Acoustic telemetry is arguably the most popular method used to study the movements of fish. Despite this method being able to elucidate many aspects of movement behavior, including residency, home range, and migration, among others, one aspect that remains challenging is the study and definition of connectivity, particularly within marine seascapes.

Truly the best of both worlds: Merging lineage-specific and universal probe kits to maximize phylogenomic inference.

Premise: Hybridization capture kits are now commonly used for reduced representation approaches in genomic sequencing, with both universal and clade-specific kits available. Here, we present a probe kit targeting 799 low-copy genes for the plant family Annonaceae.

Methods: This new version of the kit combines the original 469 genes from the previous Annonaceae kit with 334 genes from the universal Angiosperms353 kit.

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.

How fast are viruses spreading in the wild?

Genomic data collected from viral outbreaks can be exploited to reconstruct the dispersal history of viral lineages in a two-dimensional space using continuous phylogeographic inference. These spatially explicit reconstructions can subsequently be used to estimate dispersal metrics that can be informative of the dispersal dynamics and the capacity to spread among hosts. Heterogeneous sampling efforts of genomic sequences can however impact the accuracy of phylogeographic dispersal metrics.

TPR is required for cytoplasmic chromatin fragment formation during senescence.

During oncogene-induced senescence there are striking changes in the organisation of heterochromatin in the nucleus. This is accompanied by activation of a pro-inflammatory gene expression programme - the senescence-associated secretory phenotype (SASP) - driven by transcription factors such as NF-κB. The relationship between heterochromatin re-organisation and the SASP has been unclear.

Pulmonary fibrosis in patients with autoimmune pulmonary alveolar proteinosis: a retrospective nationwide cohort study.

Background: Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare disease that may progress towards pulmonary fibrosis. Data about fibrosis prevalence and risk factors are lacking.

Methods: In this retrospective multicentre nationwide cohort, we included patients newly diagnosed with aPAP between 2008 and 2018 in France and Belgium.

Cyclophostin and Cyclipostins analogues counteract macrolide-induced resistance mediated by erm(41) in Mycobacterium abscessus.

Background: Mycobacterium abscessus is an emerging pathogen causing severe pulmonary infections, particularly in individuals with underlying conditions, such as cystic fibrosis or chronic obstructive pulmonary disease. Macrolides, such as clarithromycin (CLR) or azithromycin (AZM), represent the cornerstone of antibiotherapy against the M. abscessus species.

From seedlings to adults: Linking survival and leaf functional traits over ontogeny.

As long-lived tropical trees grow into the multi-layered canopy and face different environmental conditions, the relationships between leaf traits and whole-plant survival can vary over ontogeny. We tested the strength and direction of the relationships between leaf traits and long-term survival data across life stages for woody species from a subtropical forest in Puerto Rico. Trait-survival relationships were largely consistent across ontogeny with conservative traits leading to higher survival rates.

Identification of risk areas for avian influenza outbreaks in domestic poultry in Mali using the GIS-MCDA approach.

Mali is a country where little information is known about the circulation of avian influenza viruses (AIVs) in poultry. Implementing risk-based surveillance strategies would allow early detection and rapid control of AIVs outbreaks in the country. In this study, we implemented a multi-criteria decision analysis (MCDA) method coupled with geographic information systems (GIS) to identify risk areas for AIVs occurrence in domestic poultry in Mali.

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.

Characterizing the Slow Dynamics of the Swap Monte Carlo Algorithm.

The swap Monte Carlo algorithm introduces nonphysical dynamic rules to accelerate the exploration of the configuration space of supercooled liquids. Its success raises deep questions regarding the nature and physical origin of the slow dynamics of dense liquids and how it is affected by swap moves. We provide a detailed analysis of the slow dynamics generated by the swap Monte Carlo algorithm at very low temperatures in two glass-forming models.

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.
