Impact of hyperuricaemia on patients with psoriatic arthritis treated with secukinumab in the FUTURE 2-5 and MAXIMISE studies.

Objectives: Patients with psoriatic arthritis (PsA) are at a significantly increased risk of hyperuricaemia and development of gout, and those with hyperuricaemia have been found to respond poorly to PsA treatment and have more peripheral and destructive joint damage. We present a comprehensive post hoc analysis using pooled data from the FUTURE 2-5 studies and the MAXIMISE study to further evaluate the impact of hyperuricaemia on clinical presentation/disease severity and response to secukinumab in patients with PsA.

Methods: Patients were stratified into two groups based on baseline serum uric acid (SUA) level (threshold of 360 µmol/L).

Examining the biological pathways underlying clinical heterogeneity in Sjogren's syndrome: proteomic and network analysis.

Objectives: Stratification approaches are vital to address clinical heterogeneity in Sjogren's syndrome (SS). We previously described that the Newcastle Sjogren's Stratification Tool (NSST) identified four distinct clinical subtypes of SS. We performed proteomic and network analysis to analyse the underlying pathobiology and highlight potential therapeutic targets for different SS subtypes.

Association Between Bruton's Tyrosine Kinase Gene Overexpression and Risk of Lymphoma in Primary Sjögren's Syndrome.

Objective: We undertook this study to analyze whole blood gene expression and to investigate the role of B cell genes in primary Sjögren's syndrome-related non-Hodgkin lymphoma (primary SS-NHL).

Methods: Peripheral whole blood samples were collected from 345 well-phenotyped patients with primary SS enrolled in the prospective Assessment of Systemic Signs and Evolution in Sjögren's Syndrome (ASSESS) cohort. Transcriptomic analysis was performed using human Clariom S Arrays (Affymetrix).

Spin- and angle-resolved inverse photoemission setup with spin orientation independent from electron incidence angle.

A new spin- and angle-resolved inverse photoemission setup with a low-energy electron source is presented. The spin-polarized electron source, with a compact design, can decouple the spin polarization vector from the electron beam propagation vector, allowing one to explore any spin orientation at any wavevector in angle-resolved inverse photoemission. The beam polarization can be tuned to any preferred direction with a shielded electron optical system, preserving the parallel beam condition.
