Treatment selection in the clinical practice of systemic lupus erythematosus: Results from the Kyushu Collagen Disease Network for Systemic Lupus Erythematosus (KCDN-SLE) registry.

Objectives: This study aimed to describe the treatment selection for systemic lupus erythematosus (SLE) using data from the Kyushu Collagen Disease Network for SLE (KCDN-SLE) registry, a multicentre prospective registry in Japan.

Methods: This study used data from patients registered between August 2022 and November 2023. Clinical characteristics, purpose of agent initiation, other candidate agents, and short-term efficacy and safety were evaluated.

GWAS for systemic sclerosis identifies six novel susceptibility loci including one in the Fcγ receptor region.

Here we report the largest Asian genome-wide association study (GWAS) for systemic sclerosis performed to date, based on data from Japanese subjects and comprising of 1428 cases and 112,599 controls. The lead SNP is in the FCGR/FCRL region, which shows a penetrating association in the Asian population, while a complete linkage disequilibrium SNP, rs10917688, is found in a cis-regulatory element for IRF8. IRF8 is also a significant locus in European GWAS for systemic sclerosis, but rs10917688 only shows an association in the presence of the risk allele of IRF8 in the Japanese population.

Behavioral and physiological fatigue-related factors influencing timing and force control learning in pianists.

Optimizing the training regimen depending on neuromuscular fatigue is crucial for the well-being of professionals intensively practicing motor skills, such as athletes and musicians, as persistent fatigue can hinder learning and cause neuromuscular injuries. However, accurate assessment of fatigue is challenging because of the dissociation between subjective perception and its impact on motor and cognitive performance. To address this issue, we investigated the interplay between fatigue and learning development in 28 pianists during three hours of auditory-motor training, dividing them into two groups subjected to different resting conditions.

No association between methotrexate and impaired bone mineral density in a cohort of patients with polymyalgia rheumatica, giant cell arteritis, granulomatosis with polyangiitis and other vasculitides-a cross-sectional analysis with dose-response analyses.

Objective: To investigate whether methotrexate (MTX) use is associated with bone mineral density (BMD) in patients with polymyalgia rheumatica (PMR) and various forms of vasculitis.

Methods: Rh-GIOP is a cohort study designed to evaluate bone health in patients with inflammatory rheumatic diseases. This cross-sectional analysis assessed the baseline visits of all patients with PMR or any kind of vasculitis.
