Differentiated pattern of complement system activation between MOG-IgG-associated disease and AQP4-IgG-positive neuromyelitis optica spectrum disorder.

Background: Myelin oligodendrocyte glycoprotein antibody (MOG) immunoglobulin G (IgG)-associated disease (MOGAD) has clinical and pathophysiological features that are similar to but distinct from those of aquaporin-4 antibody (AQP4-IgG)-positive neuromyelitis optica spectrum disorders (AQP4-NMOSD). MOG-IgG and AQP4-IgG, mostly of the IgG1 subtype, can both activate the complement system. Therefore, we investigated whether the levels of serum complement components, regulators, and activation products differ between MOGAD and AQP4-NMOSD, and if complement analytes can be utilized to differentiate between these diseases.

Objective: To evaluate the efficacy of prednisolone in the treatment of medication-overuse headache (MOH) using data from a multicenter prospective registry (Registry for Load and Management of Medication Overuse Headache [RELEASE]).

Background: The treatment of MOH is challenging, especially when withdrawal headache manifests during the cessation of overused medication. Although systemic corticosteroids have been empirically used to reduce withdrawal headaches, their efficacy on the long-term outcomes of MOH has not been documented.

Creative Self-Efficacy, Cognitive Reappraisal, Positive Affect, and Career Satisfaction: A Serial Mediation Model.

With a substantial body of research supporting the critical role of positive affect in improving work outcomes and enhancing career success, investigating the factors that facilitate emotion regulation strategies for fostering positive affect becomes an important research question. In this context, our study explores the association between strong creative self-efficacy and high cognitive reappraisal-an established and potent emotion regulation strategy known to increase positive affect. We propose a model wherein high levels of creative self-efficacy lead to a tendency for cognitive reappraisal, resulting in high levels of positive affect that ultimately contribute to greater career satisfaction.
