Clinical Characterization and Long-Term Outcome in Children and Adults With Anti-AMPA Receptor Encephalitis.

Background And Objectives: Anti-alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor (anti-AMPAR) encephalitis manifests as limbic encephalitis in adults and is often associated with cancer. Although some reports suggest that it may occur in children, the clinical features in this population, as well as the prognostic factors and long-term outcomes in children and adults, are unknown.

Methods: We performed a retrospective, international collaborative study of patients with anti-AMPAR encephalitis.

Immune Checkpoint Inhibitors Trigger and Exacerbate Anti-CV2/CRMP5 Paraneoplastic Neurologic Syndromes.

Background And Objectives: Immune checkpoint inhibitors (ICIs) are oncologic treatments that may trigger or worsen paraneoplastic neurologic syndromes (PNSs). This study describes patients with CV2/CRMP5-PNS treated by ICI, compares the post-ICI group with ICI-naïve patients with CV2/CRMP5-PNS, and estimates the overall survival of ICI-treated patients with CV2/CRMP5-PNS, Hu-PNS, and Ma2-PNS.

Methods: The medical records of patients positive for anti-CV2/CRMP5 antibodies were retrospectively reviewed at the French Reference Centre to identify those treated with ICI (2016-2024).

Relapses in Anti-NMDAR Encephalitis: Clinical Characterization and Predictive Features.

Background And Objectives: During the recovery phase of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, up to 25% of relapses have been reported. Herein, we aimed to clinically characterize these relapses, analyze potential clinical predictors during the first episode, and evaluate the impact of immunotherapy in their occurrence.

Methods: This was a retrospective observational study of patients diagnosed with anti-NMDAR encephalitis relapses between January 2007 and June 2022 at the French Reference Center for Paraneoplastic Neurological Syndromes and Autoimmune Encephalitis with a follow-up longer than 1 year.

Workflow for Statistical Analysis of Environmental Mixtures.

Background: Human exposure to complex, changing, and variably correlated mixtures of environmental chemicals has presented analytical challenges to epidemiologists and human health researchers. There has been a wide variety of recent advances in statistical methods for analyzing mixtures data, with most methods having open-source software for implementation. However, there is no one-size-fits-all method for analyzing mixtures data given the considerable heterogeneity in scientific focus and study design.

Environmental exposure assessment in the international prospective study of Chronic Kidney Disease of UnceRtain Etiology (CKDu) in Agricultural Communities (CURE) research consortium: Design and protocol development.

Background: Chronic kidney disease of unknown etiology (CKDu) is a major health concern among outdoor manual workers in rural Central America and South Asia. The CURE study is a prospective longitudinal cohort designed to investigate CKDu's environmental risk factors through standardized exposure assessments, questionnaires, and biological and environmental sample collection.

Methods: This manuscript details the development of a standardized exposure assessment protocol within the CKDu CURE Consortium.
