Objectives
To examine (i) the association of adiposity with pain intensity and/or effusion-synovitis in people with knee osteoarthritis (OA), adjusting for body mass index (BMI), and (ii) whether indicators of systemic immune inflammation (i.e., the systemic immune-inflammation index (SII) and the systemic immune response index (SIRI)) moderate the above associations.
Methods
Individuals with knee OA were sampled from the Western Ontario Registry for Early Osteoarthritis Knee Study. Total body and visceral fat percentages were measured using bioimpedance analysis, and effusion-synovitis was graded using knee ultrasonography. Multiple regression models with interaction terms were used to examine the association between fat percentages and pain intensity (linear)/effusion-synovitis (logistic), and the interaction effect of fat and SII/SIRI on pain intensity/effusion-synovitis. The analyses were adjusted for confounders (age, sex, BMI, radiographic severity of the opposite knee, and anxio-depressive symptoms).
Results
Data from 225 participants (mean age: 61.1 (10.9), 68% female, mean BMI: 31.7 (7.7)) were analyzed. The associations for adjusted fat and pain intensity models were as follows: total body fat: β): - 0.03 (-0.54 to 0.46) and visceral fat: β (: -0.25 (-1.03 to 0.51)., The odds ratios for adjusted fat and effusion-synovitis models were total body fat: OR): 0.98 (0.92 to 1.05) and visceral fat: OR (): 1.01 (0.91 to 1.11)). Neither the main nor the interaction effects were significant.
Conclusion
Our preliminary results do not support an association of adiposity and its interaction with generalized inflammation with pain/effusion-synovitis adjusted for BMI. Further studies are needed.

To investigate whether systemic autoimmune rheumatic diseases (SARDs) were disproportionately reported as adverse events following COVID-19 vaccination compared with other vaccines, using data from the Vaccine Adverse Event Reporting System (VAERS).
Methods
We conducted a retrospective disproportionality analysis of VAERS reports collected between December 2020 and December 2024. Reports were identified using a structured query based on MedDRA terms for specific SARDs, including polymyalgia rheumatica, giant cell arteritis, systemic lupus erythematosus, systemic sclerosis, Sjögren’s syndrome, myositis, and other vasculitides. For each disease, the proportional reporting ratio (PRR), reporting odds ratio (ROR), and Bayesian information component (IC) were calculated, comparing COVID-19 vaccines (BNT162b2, mRNA-1273, Ad26.COV2.S) with all other vaccines in VAERS. Analyses were further stratified by sex to explore consistency.
Results
Among approximately 680,000 valid adverse event reports, encompassing both COVID-19 and non–COVID-19 vaccines, no significant disproportionality signal was identified for any SARD. Polymyalgia rheumatica, giant cell arteritis, systemic lupus erythematosus, systemic sclerosis, Sjögren’s syndrome, and myositis showed no evidence of disproportionate reporting following COVID-19 vaccination. The category “other vasculitides” displayed a lower reporting frequency following COVID-19 vaccination compared with other vaccines. Stratified analyses yielded consistent findings across sex subgroups.
Conclusion
In a large national pharmacovigilance dataset, COVID-19 vaccines were not associated with a disproportionate increase in reports of any SARD. These results support the favorable safety profile of COVID-19 vaccines with respect to autoimmune rheumatic events, while highlighting the value of ongoing post-marketing surveillance for rare immune-mediated reactions.

Background
Knee osteoarthritis (KOA) is a leading cause of disability worldwide; however current therapies offer only symptomatic relief. Metformin, a widely used antidiabetic agent, has been demonstrated to have anti-inflammatory and chondroprotective effects in preclinical models, suggesting its KOA modifying properties.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials evaluating the effects of metformin in patients with KOA. A comprehensive search of PubMed, Embase, and Cochrane Library was performed up to May 2025. Two reviewers independently screened studies and extracted data. Statistical analyses were conducted using a random-effects model to account for between-study heterogeneity. Subgroup analyses based on formulation, treatment duration, and nonsteroidal anti-inflammatory drugs (NSAIDs) co-administration were also performed.
Results
Five studies (n = 337) were included. Metformin significantly reduced pain scores (standardized mean difference [SMD] = −1.295; 95 % confidence interval [CI]: −2.063 to −0.526) and stiffness (SMD = −0.746; 95 % CI: −1.385 to −0.107), improved physical function (SMD = −2.042; 95 % CI: −3.372 to −0.712), and health-related quality of life (SMD = −1.505; 95 % CI: −2.896 to −0.115). Effects were consistent regardless of oral or topical metformin use, treatment duration, and NSAID use, although the benefits were greater when metformin was combined with NSAIDs.
Conclusion
While metformin demonstrated consistent benefits in pain and functional outcomes, these findings should be interpreted as symptomatic and adjunctive effects rather than definitive disease modification. Future trials incorporating structural endpoints are needed to confirm disease-modifying potential.

Objectives
To empirically compare the discriminant capacities of three outcome measurement instruments for assessment of physical functioning for psoriatic arthritis (PsA): HAQ-DI, SF36-PF and SF36-PCS.
Methods
We applied a network meta-analysis technique in a sample of randomized trials (RCTs) for PsA. For randomized comparison, we calculated net effect size estimates for each outcome measurement instrument using standardized mean differences (SMDs); positive values indicated a beneficial effect of the intervention compared to the control groups. We analyzed the differences between outcome measurement instruments at the trial level by applying a multiple-treatment meta-analysis to compare the SMDs within and across randomized comparisons for each outcome measurement instrument.
Results
From 42 articles (31 RCTs), 57, 18, and 18 randomized comparisons enabled a direct comparison between HAQ-DI and SF36-PCS (difference in SMDs: 0.057, 95 % confidence interval, CI: 0.003 to 0.110), SF36-PF and SF36-PCS (difference in SMDs: 0.101, 95 % CI: 0.018 to 0.184); and HAQ-DI and SF36-PF (difference in SMDs:0.059, 95 % CI:0.142 to 0.024), respectively. The network meta-analysis technique confirmed that both HAQ-DI and SF36-PF were more responsive to change than SF36-PCS, with differences between SMDs of 0.057 (95 % CI: 0.003 to 0.110) and 0.109 (95 % CI: 0.032 to 0.185), respectively. No difference in discriminatory capacity between HAQ-DI and SF36-PF was noted.
Conclusions
HAQ-DI and SF-36-PF were equally responsive to change and superior to SF36-PCS in PsA RCTs. We illustrated a new method for quantitative comparison of the performance of different outcome measurement instruments for a particular domain.
