Blood-Based Biomarkers for Identifying Disease Activity in AQP4-IgG-Positive Neuromyelitis Optica Spectrum Disorder.

Importance: The temporal dynamics of serum glial fibrillary acidic protein (sGFAP) and serum neurofilament light chain (sNfL) as biomarkers of disease activity for neuromyelitis optica spectrum disorder (NMOSD) remain underexplored.

Objective: To determine optimal timing for assessing sGFAP and sNfL, establish cutoff values differentiating between attacks and remissions in NMOSD, and evaluate these findings across independent cohorts.

Design, Setting, And Participants: This retrospective, longitudinal, multicenter cohort study was conducted among patients with aquaporin-4 antibody (AQP4-IgG)-positive NMOSD.

Impact of the Metal-Organic Frameworks Polymorphism on the Electrocatalytic Properties of CeO toward Oxygen Evolution.

Hydrogen (H) is a viable alternative as a sustainable energy source, however, new highly efficient electrocatalysts for water splitting are still a research challenge. In this context, metal-organic frameworks (MOFs)-derived nanomaterials are prominent high-performance electrocatalysts for hydrogen production, especially in the oxygen evolution reaction (OER). Here, a new synthesis of two cerium oxide (CeO) electrocatalysts using Ce-succinates MOFs as templates is proposed.

Neurofilament Light Chain as a Discriminator of Disease Activity Status in MOG Antibody-Associated Disease.

Background And Objectives: In patients with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD), acute disease activity is generally identified through medical history, neurologic examination, and imaging. However, these may be insufficient for detecting disease activity in specific conditions. This study aimed to investigate the dynamics of serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) after clinical attacks and to assess their utility in discriminating attacks from remission in patients with MOGAD.

Knowledge of the nursing team about cardiac arrest and cardiopulmonary resuscitation: mixed methods studies.

Objective: To analyze the knowledge and perceptions of the nursing team about arrest and cardiopulmonary resuscitation in adults before and after in situ simulation in emergency care.

Method: A sequential explanatory mixed methods study conducted in an Emergency Care Unit. Quantitative data were obtained through pre- and post-simulation questionnaire answered by 21 professionals and analyzed using descriptive and inferential statistics.

Dynamic Response of Masonry Structures to Temperature Variations: Experimental Investigation of a Brick Masonry Wall.

Structural health monitoring (SHM) is essential for preserving historical and modern infrastructure by tracking dynamic properties such as frequencies and mode shapes. Changes in these properties can indicate structural damage, but environmental factors like temperature can also cause similar variations, complicating damage detection. This study investigates from an experimental point of view the effect of temperature on the dynamic behaviour of masonry structures, focusing on a masonry wall subjected to thermal load variations within operational conditions.
