This study aims to apply the synovitis assessment in routine care of naïve Rheumatoid Arthritis (RA) and to develop a multiparametric nomogram for baseline diagnostic and treatment response prediction.

1015 patients [545 RA, 167 Psoriatic Arthritis (PsA), 199 Undifferentiated Peripheral Inflammatory Arthritis (UPIA), 18 crystal arthritis, 26 connective tissue diseases and 60 osteoarthritis (OA)] undergoing ultrasound (US)-guided synovial tissue (ST) biopsy were enrolled (SYNGem) and stratified based on disease phase. The Krenn synovitis score(KSS) was assessed and integrated with disease characteristics and clinical outcome and a nomogram was created incorporating predictors of "DAS-Remission achievement at 6 months" in naïve RA treated with a treat to target strategy.

KSS significantly differs among patients with RA, as well as PsA and UPIA, when compared to OA. In RA, KSS directly correlated with DAS28 and was related to autoantibody positivity in naïve RA. Moreover, naïve RA achieving 6 months DAS-remission had, at baseline, lower KSS, shorter symptoms duration (VERA) and lower disease activity than naïve RA not achieving DAS-remission. On logistic regression, being VERA, not having high disease activity and having a KSS<5 at baseline, were synergistic factors of DAS-remission achievement at 6 months and a nomogram integrating baseline clinical and histological characteristics of naïve RA enabled to predict up to 81.7% of probability to achieve 6 months DAS-remission.

KSS is a reliable tool for synovitis assessment on US-guided ST biopsies being contingent on disease phase, autoimmune profile and integrated within a therapeutic response predictive nomogram in naïve RA.

Here we show that magic-angle spinning (MAS) solid-state NMR can be used to assess the structure of the influenza virus hemagglutinin stalk long alpha helix antigen, both in its free, unformulated form and once chemically coupled to the surface of large virus-like particles (VLPs). The sensitivity boost provided by high-field dynamic nuclear polarization (DNP) and proton detection at fast MAS rates allows to overcome the penalty associated with the antigen dilution. Comparison of the MAS NMR fingerprints between the free and VLP-coupled forms of the antigen provides structural evidence of the conservation of its native fold upon bioconjugation.

Eosinophilic granulomatosis with polyangiitis (EGPA, formerly Churg-Strauss syndrome) is a rare anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Environmental agents and occupational exposures may confer susceptibility to EGPA, but data are scarce. We investigated the association between occupational exposures (e.g., silica, farming, asbestos, organic solvents) and other environmental agents (e.g., smoking) and the risk of EGPA.

One-hundred and eleven newly diagnosed EGPA patients and 333 controls matched for age, sex and geographic area of origin were recruited at a national referral centre for EGPA. Exposures were assessed using a dedicated questionnaire administered by a blinded specialist in occupational medicine.

Exposures to silica [OR 2.79 (95% CI 1.55-5.01), p=0.001], organic solvents [OR 3.19 (95% CI 1.91-5.34), p<0.001], and farming [OR 2.71 (95% CI 1.71-4.29), p<0.001] were associated with an increased risk of EGPA. Co-exposure to silica and farming yielded an OR of 9.12 (95% CI 3.06-27.19) (p<0.001), suggesting a multiplicative effect between these two exposures. Smoking (current and former smokers combined) was significantly less frequent among cases than among controls [OR 0.49 (95% CI 0.29-0.70), p<0.001)]. The pack-year index was also lower among cases [OR 0.96 (95% CI 0.94-0.98), p<0.001]. The associations with silica and farming were primarily aligned with ANCA-positive EGPA, those with smoking and solvents with ANCA-negative EGPA.

The environment influences the susceptibility to EGPA exposures to organic solvents, silica, and farming are associated with an increased risk of the disease, while smoking with a lower risk. These exposures seem to have distinct effects on EGPA subsets.

We report the first case of a 12-year-old Japanese male with haploinsufficiency of R3HDM1. He presented with mild intellectual disability (ID) and developmental delay. He had a pericentric inversion of 46,XY,inv(2)(p16.1q21.3)dn with breakpoints in intron 19 of R3HDM1 (2q21.3) and the intergenic region (2p16.1). The R3HDM1 levels in his lymphoblastoid cells were reduced to approximately half that of the healthy controls. However, the expression of MIR128-1, in intron 18 of R3HDM1, was not affected via the pericentric inversion. Knockdown of R3HDM1 in mouse embryonic hippocampal neurons suppressed dendritic growth and branching. Notably, the Database of Genomic Variants reported the case of a healthy control with a 488-kb deletion that included both R3HDM1 and MIR128-1. miR-128 has been reported to inhibit dendritic growth and branching in mouse brain neurons, which directly opposes the novel functions of R3HDM1. These findings suggest that deleting both R3HDM1 and MIR128-1 alleviates the symptoms of the disease caused by loss-of-function mutations in R3HDM1 only. Thus, haploinsufficiency of R3HDM1 in the patient may be the cause of the mild ID due to the genetic imbalance between R3HDM1 and MIR128-1.
