Article Synopsis
  • The study aimed to compare disability progression between primary progressive multiple sclerosis (PPMS) patients treated with anti-CD20 therapies (rituximab and ocrelizumab) and a control group that was untreated.
  • Data was gathered retrospectively from the French MS registry, including factors like time to confirmed disability progression (CDP), relapse rates, and MRI activity in patients from 2016 to 2021.
  • Results showed no significant difference in CDP or MRI activity between treated and untreated groups, although a trend suggested treated patients might experience fewer relapses, warranting further investigation.

  • MOGAD (myelin oligodendrocyte glycoprotein antibody-associated disease) is a new autoimmune disorder, and this study aims to examine the long-term outcomes and factors affecting relapse in adult patients.
  • The research included 128 patients from a French cohort with a follow-up period averaging over 6.5 years; results showed that a significant portion experienced relapses, with specific onset symptoms such as optic neuritis and myelitis.
  • Findings indicated that starting maintenance treatment after the first attack is linked to lower relapse risk, with notable impact on patients' disability scores over time.

Article Synopsis
  • Researchers sequenced the genomes of 822 families with suspected rare monogenic diseases that were previously undiagnosed through standard genetic tests, including exome sequencing.
  • They found that genome sequencing provided a molecular diagnosis for 29.3% of the initial families, with 8.2% requiring genome sequencing to identify variants that exome sequencing missed.
  • The study showed that both research and clinical approaches could benefit from genome sequencing, demonstrating its importance in uncovering previously undetected genetic variations.

Objectives: Impaired perivascular clearance has been suggested as a contributing factor to the pathogenesis of Alzheimer disease (AD). However, it remains unresolved when the anatomy of the perivascular space (PVS) is altered during AD progression. Therefore, this study investigates the association between PVS volume and AD progression in cognitively unimpaired (CU) individuals, both with and without subjective cognitive decline (SCD), and in those clinically diagnosed with mild cognitive impairment (MCI) or mild AD.

Purpose: Prolonged shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been observed in immunocompromised hosts. Early monotherapy with direct-acting antivirals or monoclonal antibodies, as recommended by the international guidelines, does not prevent this with certainty. Dual therapies may therefore have a synergistic effect.

A narrow structure in the pΛ[over ¯] system near the mass threshold, named as X(2085), is observed in the process e^{+}e^{-}→pK^{-}Λ[over ¯] with a statistical significance greater than 20σ. Its spin and parity are determined for the first time to be J^{P}=1^{+} in an amplitude analysis, with a statistical significance greater than 5σ over other quantum numbers (0^{-},1^{-} and 2^{+}). The pole positions of X(2085) are measured to be M_{pole}=(2084_{-2}^{+4}±9)  MeV and Γ_{pole}=(58_{-3}^{+4}±25)  MeV, where the first uncertainties are statistical and the second ones are systematic.

Background: Persons with multiple sclerosis (pwMS) might be particularly well suited to benefit from digital health applications because they are, on average, younger and less severely disabled than patients with many other chronic diseases. Many digital health applications for pwMS have been developed.

Objectives: Analysis of the evidence of digital health applications to improve health outcomes from a patient perspective.

Article Synopsis
  • This study compares two methods for estimating death probabilities in multiple sclerosis (MS) patients: the Cause-Specific Framework (CSF) which requires known causes of death, and the Excess Mortality Framework (EMF) which does not.
  • Using data from a large MS registry and a subset with detailed death records, the researchers found that EMF generally estimated higher death probabilities than CSF across different age groups.
  • Overall, the analysis revealed varying mortality probabilities for MS patients based on the initial disease type, sex, and age; with significant differences particularly noted between relapsing-onset MS and primary progressive patients over a 30-year follow-up.

Background And Objectives: The question of the long-term safety of pregnancy is a major concern in patients with multiple sclerosis (MS), but its study is biased by reverse causation (women with higher disability are less likely to experience pregnancy). Using a causal inference approach, we aimed to estimate the unbiased long-term effects of pregnancy on disability and relapse risk in patients with MS and secondarily the short-term effects (during the perpartum and postpartum years) and delayed effects (occurring beyond 1 year after delivery).

Methods: We conducted an observational cohort study with data from patients with MS followed in the Observatoire Français de la Sclérose en Plaques registry between 1990 and 2020.

Precision oncology relies on the accurate molecular characterization of individual patients with cancer at the time of treatment initiation. However, tumor molecular profiles are not static, and cancers continually evolve because of ongoing mutagenesis and clonal selection. Here, we performed genomic analyses of primary tumors, metastases, and plasma collected from individual patients to define the concordance of actionable genomic alterations and to identify drivers of metastatic disease progression.

Circulating tumor DNA (ctDNA) sequencing guides therapy decisions but has been studied mostly in small cohorts without sufficient follow-up to determine its influence on overall survival. We prospectively followed an international cohort of 1,127 patients with non-small-cell lung cancer and ctDNA-guided therapy. ctDNA detection was associated with shorter survival (hazard ratio (HR), 2.

Article Synopsis
  • SARS-CoV-2 is evolving rapidly, with new variants that have higher transmissibility and the potential to evade immune responses despite existing vaccines and antibodies.
  • The ongoing evolution of the virus, particularly in its Spike protein, exerts selection pressure that could lead to more immune-resistant variants.
  • To address this challenge, researchers developed a deep learning method to redesign specific regions of antibodies, resulting in one that effectively neutralizes multiple SARS-CoV-2 variants.

SARS-CoV-2 infection is a major global public health concern with incompletely understood pathogenesis. The SARS-CoV-2 spike (S) glycoprotein comprises a highly conserved free fatty acid binding pocket (FABP) with unknown function and evolutionary selection advantage. Deciphering FABP impact on COVID-19 progression is challenged by the heterogenous nature and large molecular variability of live virus.

Rationale: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.
