Annual fitness assessments are performed during group exercise therapy for people with axial Spondyloarthritis (axSpA) living in Switzerland. The core strength test (CST) is time-consuming, and interpretation limited. Thus, the objectives were to 1) compare the CST-performance of people with axSpA and healthy controls, and 2) evaluate if hand grip strength can be used as a proxy for core strength.

This study examined to examine the relationship of Epstein-Barr virus (EBV) in rheumatoid arthritis (RA) by evaluating disease activity and autoantibody levels in positive and negative cases using the anti-EBV early antigen diffuse type and restricted type (EA-DR) immunoglobulin G (IgG) antibody.

The objective of this study was to examine whether foot/ankle injury and injection contribute to the risk of foot/ankle OA in retired UK male professional footballers.

Systemic vasculitides are rare, heterogeneous, inflammatory disorders associated with high morbidity and mortality. Recent therapeutic advancements have improved life expectancy and reproductive opportunities for patients with vasculitis, but research on preterm delivery, maternal pregnancy complications, and medication use is limited. We aimed to investigate pregnancy outcomes in patients with systemic vasculitis using administrative claims data.

Rheumatoid arthritis increases the risk of generalised muscle wasting, with chronic inflammation contributing to the loss of muscle mass and strength. Tofacitinib, a Janus kinase (JAK) inhibitor used to treat rheumatoid arthritis, increases serum creatinine concentrations without conclusive evidence of nephrotoxicity. In the Rheumatoid Arthritis and Muscle (RAMUS) study, we investigated whether tofacitinib affects muscle volume, strength, and function.

Idiopathic inflammatory myopathies are a heterogeneous group of chronic autoimmune diseases characterized by inflammation and muscle weakness. In Colombia, these conditions have been poorly studied. Therefore, an analysis of the prevalence and demographic characteristics of the main reported inflammatory myopathies in the country (dermatomyositis and polymyositis) was carried out, based on data from the Ministry of Health.

Axial spondyloarthritis (axSpA) exhibits notable sex-related differences, particularly in Asian populations, influenced by genetic, cultural, and healthcare factors. This systematic review and meta-analysis assess sex-specific disparities in axSpA among Asian patients.

Synovial tissue is widely considered to be a strong candidate for contributing to the development of individualised therapeutic strategies for the treatment and management of rheumatoid arthritis. Recently, several factors have enabled major developments in synovial tissue analysis: (1) improvement in synovial tissue biopsy techniques; (2) availability of powerful biotechnologies with increasing granularity; (3) recruitment of larger cohorts of patients; (4) development of recommendations to standardise synovial tissue analysis; and (5) an expanded therapeutic armamentarium of targeted therapies. Although recent studies have suggested the existence of rheumatoid arthritis subtypes based on the synovial tissue inflammatory profile, with potential therapeutic implications, other studies have yielded different results. In this Viewpoint we discuss and contextualise the findings of recent major studies in the field of synovial tissue. We highlight how disease activity, synovial tissue inflammatory burden, and response to therapy are interdependent features in rheumatoid arthritis, both earlier and later in the disease course. From there, we discuss how this multidirectional relationship has impacted (and potentially influenced the interpretation of) the findings of synovial tissue-based studies. Finally, we discuss the different hypotheses explaining the link between synovial tissue, clinical features, and therapeutic response.

Immune-mediated vascular endothelial injury is considered one of the earliest pathological features in systemic sclerosis and is thought to occur simultaneously within a broad range of organs, although typically clinically manifesting only as Raynaud's phenomenon in the early stages. Overt vascular systemic sclerosis manifestations include Raynaud's phenomenon, abnormal nailfold capillary morphology, digital ulcers, pulmonary arterial hypertension, cardiovascular disease (primary and coronary), telangiectasia, renal crisis, and gastric antral vascular ectasia. Tissue ischaemia might also contribute to aberrant tissue remodelling, resulting in calcinosis and fibrosis. Recognition of the substantial inter-relationship between these vascular complications is growing; examples of vascular treatment interventions targeting digital vasculopathy having off-target vascular benefits in other organs have been reported. In general, treatment of life-threatening vascular complications, such as pulmonary arterial hypertension, is not commenced until classifiable organ disease has occurred; however, the identification of robust prognostic biomarkers might allow such complications to be averted with preventative disease modification. In this Personal View, we describe the inter-relationship between vascular features of systemic sclerosis. We consider how these features might be exploited to establish a unified vascular conceptual framework that can inform the development of both predictive composite indices to guide preventative intervention, and a unified vascular composite endpoint model that can effectively capture clinically meaningful disease modification in future clinical trials of vasoactive treatments in systemic sclerosis.

Evaluation of risk factors and screening strategies for rheumatoid arthritis-associated interstitial lung disease (ILD) in patients with early rheumatoid arthritis has been scarce. We investigated the prevalence of rheumatoid arthritis-associated ILD, risk factors, and the performance of proposed screening methods for rheumatoid arthritis-associated ILD in patients with early rheumatoid arthritis.

Socioeconomic deprivation as a fracture risk factor remains underexplored. We evaluated associations between deprivation indices and bone health outcomes in a UK clinical population.

This study aimed to establish the role of myositis-specific antibodies (MSAs) in the association between type I interferon (IFN-I) plasma levels and disease activity in juvenile dermatomyositis (JDM).

Biologic therapies for skin psoriasis (PsO) have been linked to a lower risk of developing psoriatic arthritis (PsA), but their efficacy across different mechanisms of action remains to be fully explored. This study aimed to compare PsA risk in PsO patients prescribed interleukin-23 inhibitors (IL23i) vs interleukin-17 inhibitors (IL17i).

Despite significant vascular inflammation, the relationship between Behçet's syndrome (BS) and atherosclerotic cardiovascular (CV) disease remains unclear. This study aimed to evaluate coronary artery involvement in asymptomatic male BS patients and matched controls using coronary computed tomography angiography (CCTA).
