Meta-Analysis
BACKGROUND
Many international clinical guidelines recommend therapeutic exercise as a core treatment for knee and hip osteoarthritis. We aimed to identify individual patient-level moderators of the effect of therapeutic exercise for reducing pain and improving physical function in people with knee osteoarthritis, hip osteoarthritis, or both.
METHODS
We did a systematic review and individual participant data (IPD) meta-analysis of randomised controlled trials comparing therapeutic exercise with non-exercise controls in people with knee osteoathritis, hip osteoarthritis, or both. We searched ten databases from March 1, 2012, to Feb 25, 2019, for randomised controlled trials comparing the effects of exercise with non-exercise or other exercise controls on pain and physical function outcomes among people with knee osteoarthritis, hip osteoarthritis, or both. IPD were requested from leads of all eligible randomised controlled trials. 12 potential moderators of interest were explored to ascertain whether they were associated with short-term (12 weeks), medium-term (6 months), and long-term (12 months) effects of exercise on self-reported pain and physical function, in comparison with non-exercise controls. Overall intervention effects were also summarised. This study is prospectively registered on PROSPERO (CRD42017054049).
FINDINGS
Of 91 eligible randomised controlled trials that compared exercise with non-exercise controls, IPD from 31 randomised controlled trials (n=4241 participants) were included in the meta-analysis. Randomised controlled trials included participants with knee osteoarthritis (18 [58%] of 31 trials), hip osteoarthritis (six [19%]), or both (seven [23%]) and tested heterogeneous exercise interventions versus heterogeneous non-exercise controls, with variable risk of bias. Summary meta-analysis results showed that, on average, compared with non-exercise controls, therapeutic exercise reduced pain on a standardised 0-100 scale (with 100 corresponding to worst pain), with a difference of -6·36 points (95% CI -8·45 to -4·27, borrowing of strength [BoS] 10·3%, between-study variance [τ] 21·6) in the short term, -3·77 points (-5·97 to -1·57, BoS 30·0%, τ 14·4) in the medium term, and -3·43 points (-5·18 to -1·69, BoS 31·7%, τ 4·5) in the long term. Therapeutic exercise also improved physical function on a standardised 0-100 scale (with 100 corresponding to worst physical function), with a difference of -4·46 points in the short term (95% CI -5·95 to -2·98, BoS 10·5%, τ 10·1), -2·71 points in the medium term (-4·63 to -0·78, BoS 33·6%, τ 11·9), and -3·39 points in the long term (-4·97 to -1·81, BoS 34·1%, τ 6·4). Baseline pain and physical function moderated the effect of exercise on pain and physical function outcomes. Those with higher self-reported pain and physical function scores at baseline (ie, poorer physical function) generally benefited more than those with lower self-reported pain and physical function scores at baseline, with the evidence most certain in the short term (12 weeks).
INTERPRETATION
There was evidence of a small, positive overall effect of therapeutic exercise on pain and physical function compared with non-exercise controls. However, this effect is of questionable clinical importance, particularly in the medium and long term. As individuals with higher pain severity and poorer physical function at baseline benefited more than those with lower pain severity and better physical function at baseline, targeting individuals with higher levels of osteoarthritis-related pain and disability for therapeutic exercise might be of merit.

BACKGROUND
Identifying subjects at risk of imminent psoriatic arthritis (PsA) would allow these subjects to participate in therapeutic interventions to delay or prevent PsA development.
METHODS
A systematic literature review (SLR) was conducted in 2021 in Medline, Embase, PubMed, Central databases and international congress abstracts (PROSPERO CRD42022255102). All articles reporting the characteristics of patients transitioning from psoriasis (PsO) to PsA and from undifferentiated arthritis (UA) to PsA were included. Clinical and imaging characteristics were collated before PsA onset and at time of PsA diagnosis.
RESULTS
Eighteen of 23 576 references evaluated for PsO/PsA transition were analysed; 14 were cohort studies, 2 case-control studies. Two SLRs were used to enrich the project but were not analysed per se. Of 7873 references focusing on UA to PsA, 3 studies were included. Meta-analysis was not possible due to excessive data heterogeneity. Patients with PsO who developed PsA often reported joint pain, joint tenderness and functional limitations. Arthralgia (PsO, n=669; incident PsA, n=99) was associated with subsequent PsA development. On imaging, subclinical enthesopathy (PsO=325; Incident PsA=39) appeared linked to later PsA development. At the time of PsA onset (incident PsA, N=214), peripheral arthritis, mainly oligo-arthritis (ie, the mean number of swollen joints ranged from 1.5 to 3.2), was the most frequent pattern of clinical presentation.
CONCLUSIONS
Joint pain, arthralgia and entheseal involvement detected by imaging were frequent in individuals with PsO at risk for imminent PsA. Very early PsA was mainly oligoarticular. This review informed a EULAR taskforce on transition to PsA.

Meta-Analysis
OBJECTIVES
Among the over 80 different autoimmune diseases, psoriasis (PsO), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) are common representatives. Previous studies indicated a potential link with cancer risk, but suffered often from low statistical power. Thus, we aimed to synthesize the evidence and quantify the association to different female-specific cancer sites.
METHODS
The systematic review was performed according to PRISMA guidelines. A search string was developed for the databases PubMed, Web of Science, Cochrane Library and Embase. Results were screened independently by two investigators and the risk of bias was assessed using the ROBINS-E tool. Meta-analyses were performed using inverse variance weighted random-effects models. Statistical between-study heterogeneity was quantified by calculating Cochran's Q, τ, and Higgins' I statistics. Sources of heterogeneity were analyzed and adjusted for within an intensive bias assessment in the form of meta-regression, outlier, influential, and subgroup analyses. A range of methods were used to test and adjust for publication bias.
RESULTS
Of 10,096 records that were originally identified by the search strategy, 45 were included in the meta-analyses. RA was inversely associated with both breast and uterine cancer occurrence, while PsO was associated with a higher breast cancer risk. Outlier-adjusted estimates confirmed these findings. Bias assessment revealed differences in geographic regions, particularly in RA patients, with higher estimates among Asian studies. An additional analysis revealed no association between psoriatic arthritis and breast cancer.
CONCLUSIONS
RA seems to reduce the risk of breast and uterine cancers, while PsO appears to increase breast cancer risk. Further large studies are required to investigate potential therapy-effects and detailed biological mechanisms.

Comparative Study Meta-Analysis Review
OBJECTIVE
In this systematic review, we estimate the prevalence of six types of arthritis in Africa; namely rheumatoid arthritis, osteoarthritis, juvenile arthritis, psoriatic arthritis, gout, and ankylosing spondylitis.
METHODS
We comprehensively searched literature on 31 August 2014 in MEDLINE, EMBASE, Web of Science and the Cochrane Library to identify eligible studies from 1975 up to 31 July 2014. Two review authors independently selected studies, extracted data, and appraised studies. We carried out random effects meta-analysis of prevalence of arthritis and assessed heterogeneity through subgroup analyses. We performed separate analyses for population- and hospital-based studies, as well as rural and urban settings.
MAIN FINDINGS
We included 27 cross-sectional studies (20 population-based and 7 hospital-based) from Africa reporting on the prevalence of arthritis. The majority of the studies were from South Africa (44.4%, 12/27). Rheumatoid arthritis in urban settings ranged from 0.1% in Algeria, 0.6% in the DRC, to a meta-analysis overall prevalence of 2.5% in South Africa, and in rural settings ranged from a meta-analysis overall prevalence of 0.07% in South Africa, 0.3% in Egypt, to 0.4% in Lesotho. Osteoarthritis was the most prevalent form of arthritis and in urban settings it was 55.1% in South Africa and in rural settings, all in South Africa, ranged from 29.5%, 29.7%, up to 82.7% among adults aged over 65 years. Other results include highest prevalence of 33.1% for knee osteoarthritis in rural South Africa, 0.1% for ankylosing spondylitis in rural South Africa, 4.4% for psoriatic arthritis in urban South Africa, 0.7% for gout in urban South Africa, and 0.3% for juvenile idiopathic arthritis in urban Egypt. A third of the included studies had a low risk of bias (33.3%, 9/27), 40.8% (11/27) moderate risk, and 25.9% (7/27) had a high risk of bias.
CONCLUSIONS
In this systematic review, we have identified the paucity of latest prevalence data on arthritis in Africa. More studies are needed to address the prevalence and the true burden of this disease in Africa.

Review
Psoriatic arthritis (PsA) is a chronic and systemic immune disease characterized by inflammation of peripheral and/or axial joints and entheses in patients with psoriasis (PsO). Extra-articular and extracutaneous manifestations and numerous comorbidities can also be present. These recommendations replace the previous version published in May 2013. A systematic review of the literature retrieved 191 articles that were used to formulate 12 recommendations in response to 12 clinical questions, divided into 4 sections: diagnosis, non-pharmacological treatment, conventional drug therapy and biologic therapy. These guidelines provide evidence-based information on the clinical management for PsA patients. For each recommendation, the level of evidence (highest available), degree of strength (Oxford) and degree of expert agreement (interrater reliability) are reported.

Review
(1) Background: Immunological laboratory testing is known to be complex, and it is usually performed in tertiary referral centers. Many criticalities affect diagnostic immunological testing, such as limited availability, the need for specifically trained laboratory staff, and potential difficulties in collecting blood samples, especially in the most vulnerable patients, i.e., the elderly and children. For this reason, the identification of a new feasible and reliable methodology for autoantibody detection is urgently needed. (2) Methods: We designed a systematic review to investigate the available literature on the utilization of saliva samples for immunological testing. (3) Results: A total of 170 articles were identified. Eighteen studies met the inclusion criteria, accounting for 1059 patients and 671 controls. The saliva collection method was mostly represented by passive drooling (11/18, 61%), and the most frequently described methodology for antibody detection was ELISA (12/18, 67%). The analysis included 392 patients with rheumatoid arthritis, 161 with systemic lupus erythematosus, 131 with type 1 diabetes mellitus, 116 with primary biliary cholangitis, 100 with pemphigus vulgaris, 50 with bullous pemphigoids, 49 with Sjogren syndrome, 39 with celiac disease, 10 with primary antiphospholipid syndromes, 8 with undifferentiated connective tissue disease, 2 with systemic sclerosis, and 1 with autoimmune thyroiditis. The majority of the reviewed studies involved adequate controls, and saliva testing allowed for a clear distinction of patients (10/12 studies, 83%). More than half of the papers showed a correlation between saliva and serum results (10/18, 55%) for autoantibody detection, with varying rates of correlation, sensitivity, and specificity. Interestingly, many papers showed a correlation between saliva antibody results and clinical manifestations. (4) Conclusions: Saliva testing might represent an appealing alternative to serum-based testing for autoantibody detection, considering the correspondence with serum testing results and the correlation with clinical manifestations. Nonetheless, standardization of sample collection processing, maintenance, and detection methodology has yet to be fully addressed.

Meta-Analysis Review
Previous studies have shown that patients with rheumatoid arthritis (RA) have a higher susceptibility to periodontitis, but the results of individual studies remain controversial. The aim of the present meta-analysis was to comprehensively evaluate the association between RA and periodontitis. A systematic literature search was conducted in PubMed and EMBASE. Data were extracted using standardized forms, and odds ratios (OR) with 95% confidence intervals (CI) were calculated for each study. Pooled data were estimated by fixed- and random-effects models if appropriate. Eight case-control studies were included in the present study. Study size ranged from 104 to 151,569 participants. The prevalence of periodontitis in RA patients ranged from 15.5% to 100%, compared with 10.0% to 82.1% in controls. In group 1 (control) and group 2, the heterogeneity was 38% and 11%, respectively. Using fixed-effects analysis, the overall pooled estimates of the ORs for periodontitis were 4.68 (95% CI: 3.11-7.05) and 1.28 (95% CI: 1.24-1.33) in groups 1 and 2, respectively. This meta-analysis indicates that RA was significantly associated with increased overall risk of periodontitis.

Meta-Analysis
BACKGROUND
To examine the association between pregnant women with rheumatoid arthritis (RA) and the risk of preeclampsia.
METHODS
This study was registered on the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42022361571. The primary outcome was preeclampsia. Two evaluators independently reviewed the included studies, assessed their risk of bias, and extracted the data. Unadjusted and adjusted ratios with 95% confidence intervals and 95% prediction intervals were calculated. Heterogeneity was quantified using the І2 statistic, where І2 ≥ 50% indicated the presence of significant heterogeneity. Subgroup and sensitivity analyses were performed to test the robustness of the overall findings.
RESULTS
A total of 8 studies, including 10,951,184 pregnant women, of whom 13,333 were diagnosed with RA, met the inclusion criteria. Meta-analysis revealed that pregnant women with RA were significantly more likely to develop preeclampsia than those without RA (pooled odds ratio, 1.66; 95% confidence interval, 1.52-1.80; P < .001; І2 < .001).
CONCLUSION
RA during pregnancy is associated with higher odds of preeclampsia.

Meta-Analysis
BACKGROUND
Psoriatic arthritis (PsA), rheumatoid arthritis (RA) and psoriasis (PsO) are associated with systemic inflammation and increased cardiovascular mortality and morbidity. Metabolic syndrome (MetS) is associated with systemic inflammation, and conditions associated with MetS, such as obesity, are associated with difficulty in attaining minimal disease activity (MDA) in individuals with inflammatory arthritis. This systematic review aims to determine whether there is an increased prevalence of MetS in PsA populations compared with PsO and RA populations.
METHODS
A systematic review was conducted to assess the prevalence of MetS in PsA, PsO, and RA populations following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The quality of the studies reviewed was assessed using the Joanna Briggs Institute Checklist for Prevalence Studies.
RESULTS
The pooled prevalence of MetS in PsA populations was 0.46 ± 0.06 (95% CI 0.40-0.51). In comparison, the prevalence of MetS in PsO and RA populations was 0.34 ± 0.03 (95% CI 0.32-0.37) and 0.31 ± 0.04 (95% CI 0.27-0.35), respectively. Patients with PsA were 1.62 ± 0.036 (95% CI 1.50-1.74) and 1.66 ± 0.038 (95% CI 1.54-1.79) times more likely to have MetS compared with PsO and RA populations.
CONCLUSION
The prevalence of MetS is significantly increased in PsA populations compared with PsO and RA populations. Further studies should be performed using a standardized definition of MetS in PsA, RA, and PsO populations to determine whether addressing the metabolic components in MetS offers any therapeutic benefits and in terms of attaining MDA and improving cardiovascular health.

Meta-Analysis
Rheumatoid arthritis (RA) is a chronic autoimmune disease primarily affecting joints but often also associated with lung involvement such as bronchiectasis (BE). The aim of the present systematic review and meta-analysis is to provide an update on the current evidence regarding the prevalence and association between RA and BE. This systematic review and meta-analysis was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines with literature search using the terms 'Bronchiectasis AND Rheumatoid Arthritis' without a date limitation on PubMed during May 2020. A total of 28 studies fulfilled the predefined criteria and were included in the present review, with 19 being cross-sectional studies. Twenty-three studies were included in the meta-analysis. The pooled prevalence estimate was 2.69% (95% CI 1.63-4.42) in clinically defined BE, and 24.9% (95% CI 19.21-31.67) in radiologic disease. Many inconsistencies exist regarding potential risk factors for BE in RA patients such as gender, RA duration and severity, as both negative and positive associations have been reported. Although very little is known about possible causative mechanisms between RA and BE, potential pathways might be antigenic stimulation from pulmonary mucus and/or systemic inflammation from joint disease affecting the lungs. At present, the available evidence of bronchiectasis in patients with RA is insufficient to identify RA-associated risk factors for the development of BE, possibly apart from duration of RA, and, consequently, also to fully explore a possible causal relationship between the two disease. However, the increased prevalence of BE in RA patients warrants further studies to explore the association between RA and BE.
