Validation of the 2022 ACR/EULAR classification criteria for giant cell arteritis in Koran patients with giant cell arteritis.

Objectives: We applied the 2022 American College of Rheumatology (ACR)/European Alliance of Association for Rheumatology (EULAR) criteria to Korean patients previously diagnosed with giant cell arteritis (GCA) according to the 1990 ACR criteria and validated its clinical efficiency.

Methods: Nine patients with GCA were included in this study. The proportion of patients meeting each item of the 1990 ACR criteria and the 2022 ACR/EULAR criteria were assessed.

Ultrafast MRI for Pediatric Brain Assessment in Routine Clinical Practice.

Objective: To assess the feasibility of ultrafast brain magnetic resonance imaging (MRI) in pediatric patients.

Materials And Methods: We retrospectively reviewed 194 pediatric patients aged 0 to 19 years (median 10.2 years) who underwent both ultrafast and conventional brain MRI between May 2019 and August 2020.

Unveiling the Competition among Surface Damping Pathways in Single Gold Nanorods Immobilized on Graphene Using Amine Derivatives as Adsorbates.

Understanding plasmon damping in gold nanorods (AuNRs) is crucial for optimizing their use in photochemical processes and biosensing. This study used dark-field microscopy and spectroscopy to explore plasmon damping in single AuNRs on graphene monolayers (AuNR@GL) with pyridine derivatives as adsorbates. The Au-graphene heterostructure caused a Fermi-level downshift, making graphene a dominant electron acceptor.

Reclassification of the overlap syndrome of Behçet's disease and antineutrophil cytoplasmic antibody-associated vasculitis in patients with Behçet's disease.

Background/aims: This study applied the 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) criteria for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) to patients with Behçet's disease (BD) to investigate the proportion and clinical implications of the reclassification to the overlap syndrome of BD and AAV (OS-BD-AAV).

Methods: We included 280 BD patients presenting with ANCA positivity but without medical conditions mimicking AAV at diagnosis. Demographic data, items from the 2014 revised International Criteria for BD and 2022 American College of Rheumatology and European Alliance of Associations for Rheumatology criteria for AAV, ANCA positivity, and laboratory results were recorded as clinical data at diagnosis.
