RESUMO
PURPOSE: We aimed to (1) establish linguistic and ethnic equivalence (i.e. lack of bias) for the items in the English and Chinese versions of the Singapore Health and Well Being (SHAWS) Physical Functioning (PF), Positive Mindset (PM) and Social Relationship (SR) item banks (IBs); and (2) evaluate the preliminary efficiency of these IBs using Computer Adaptive Testing (CAT) simulations. METHODS: In this cross-sectional study, 671, 670, and 672 subjects answered 55, 48 and 30 items of the PF, PM, and SR IBs, respectively. Rasch analysis was conducted to assess each IB's psychometric properties, particularly the presence of differential item functioning (DIF) for language and ethnicity. A set of performance criteria related to removing items that displayed notable DIF were employed. CAT simulations determined the mean number of items for high, moderate, and moderate-low measurement precisions (stopping rule: SEM 0.300, 0.387. 0.521, respectively). RESULTS: Half of subjects were >50 years old (40.9% PF, 42.1% PM, 41.4% SR), Chinese (50.7% PF, 51.0% PM, 50.6% SR) and female (50.0% PF. 49.4% PM, 52.8% SR) respectively. Rasch analysis revealed 4 items with DIF for the PF IB, 9 items with DIF for the PM IB and 2 items with DIF for the SR IB. In CAT simulations, the mean number of items administered was 8.5, 21.6 and 14.5 for the PF, PM and SR IBs, respectively (SEM 0.300), 5.1, 13.0, 8.0 for PF, PM and SR IBs, respectively (SEM 0.387) and 3.1, 5.3 and 4.1 for PF, PM and SR IBs, respectively (SEM 0.521). CONCLUSION: The PF, PM and SR IBs to measure health-related quality of life revealed minimal DIF for language and ethnicity after remedial efforts. CAT simulations demonstrated that these IBs were efficient, especially when the stopping rule was set at moderate precision, and support the implementation of the SHAWS IBs into routine clinical care.

OBJECTIVES: To determine if there were differences in the Assessment of SpondyloArthritis international Society Health Index (ASAS HI) scores between patients classified as radiographic axial spondyloarthritis (r-axSpA) and non-radiographic axSpA (nr-axSpA), and to identify factors associated with higher ASAS HI scores in both disease phenotypes. METHODS: This study was an ancillary analysis of the ASAS HI international validation project performed in 23 countries. Patients were included if they were ≥18 years of age and diagnosed with axSpA. Univariable and multivariable analysis were performed to determine if ASAS HI scores differed between the axSpA phenotypes, and to identify other variables associated with ASAS HI scores. We also tested for potential interactions between the axSpA phenotype and significant variables identified through the multivariable regression. RESULTS: A total of 976 patients were included, with 703 having r-axSpA and 273 nr-axSpA. Patients with r-axSpA reported higher (worse) ASAS HI scores compared with those with nr-axSpA (6.8 (4.4) vs 6.0 (4.0), p=0.02), but the axSpA phenotype was not associated with ASAS HI scores in the multivariable regression (ß: -0.19, 95% CI: -0.56 to 0.19). Female gender, having worse physical function (Bath Ankylosing Spondylitis Functional Index), disease activity (Ankylosing Spondylitis Disease Activity Score) and anxiety and depressive symptoms (Hospital Anxiety and Depression Scale) were associated with higher ASAS HI scores. No interactions were found to be significant. CONCLUSION: Overall health and functioning are similarly affected in patients with r-axSpA and nr-axSpA. Female patients, having worse physical function, disease activity, anxiety and depressive symptoms were independently associated with higher ASAS HI scores.

OBJECTIVES: Chinese herbal medicine (CHM) has been shown to be effective in autoimmune rheumatic diseases, but harmful herb-drug interactions might be inherent. We aim to review the evidence regarding herb-drug interactions between immunosuppressive drugs used in autoimmune rheumatic diseases and CHM. METHODS: We searched PubMed, EMBASE and CINAHL from inception till 30 April 2023 using keywords that encompassed 'herb-drug interactions', 'herbs' and 'immunosuppressants'. Articles were included if they contained reports about interactions between immunosuppressive drugs used in the treatment of rheumatic diseases with CHM. Level of evidence for each pair of interaction was graded using the algorithm developed by Colalto. RESULTS: A total of 65 articles and 44 unique pairs of interactions were identified. HDIs were reported for cyclophosphamide, cyclosporine, tacrolimus, methotrexate, mycophenolic acid, glucocorticoids, sulfasalazine, tofacitinib and biologic disease-modifying antirheumatic drugs. Among these, cyclosporine (n = 27, 41.5%) and tacrolimus (n = 19, 29.2%) had the highest number of documented interactions. Hypericum perforatum had the highest level of evidence of interaction with cyclosporine and tacrolimus. Consumption reduced the bioavailability and therapeutic effects of the drugs. Schisandra sphenanthera had the highest level of evidence of interaction with tacrolimus and increased the bioavailability of the drug. Majority of the articles were animal studies. CONCLUSION: Overall level of evidence for the included studies were low, though interactions between cyclosporine, tacrolimus, Hypericum perforatum and Schisandra sphenanthera were the most and well-documented. Healthcare professionals should actively enquire about the concurrent use of CHM in patients, especially when drugs with a narrow therapeutic index are consumed.

Background: The COVID-19 pandemic has disrupted residency training. Several studies have been performed to investigate the impact of the pandemic on residency training in Accreditation Council for Graduate Medical Education-International (ACGME-I)-accredited institutions. However, these were either limited to certain specialties or failed to consider possible opportunities from the pandemic. Objective: To determine the stressors on residents as well as the opportunities that arose from the COVID-19 pandemic across multiple specialities in Singapore. Methods: A cross-sectional survey among SingHealth residents was conducted between July and September 2020. The survey assessed the balance between service and training during hospital postings, the pandemic's influence on examination and teaching, the psychological impact of the pandemic, the level of burnout, and the effect on morale of residents during the pandemic. Results: The response rate was 27.1% (253 of 934). Out of the 253 residents, 136 (53.8%) felt stressed during the pandemic. Concerns about family's health and safety pertaining to potential COVID-19 infection, progression in training, and completion of examinations were the top 3 stressors. One-hundred and three residents (40.7%) had their training disrupted either by being placed in an interim posting not part of their residency requirements or being deployed to care for patients with COVID-19. Although administrative support and information for virtual teaching were sufficient, only 108 (42.7%) agreed it had the same value as face-to-face sessions. Despite the challenges, 179 (70.8%) thought that experiencing this crisis provided more meaning in their career. Conclusions: The COVID-19 pandemic has brought about challenges and learning opportunities for residents.

OBJECTIVE: To determine prevalence and factors associated with flares post Coronavirus disease 2019 (COVID-19) mRNA vaccination in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and spondyloarthritis (SpA). METHODS: A retrospective multi-centre study was conducted (January 2021 to February 2022). Data were collected during index visit, defined as first post-vaccine visit in which the patient had a physician-defined flare, or if at least 3 months had elapsed since first vaccine dose, whichever came first. Factors associated with flares were identified using mixed effects Cox regression and expressed as hazard ratio (HR) and 95% confidence interval (CI). RESULTS: Total of 2377 patients were included (1563 RA, 415 PsA and 399 SpA). Among patients with RA, PsA and SpA, 21.3%, 24.1% and 21.8% experienced a flare respectively. Of those who experienced a flare, only 10.2%, 11.0% and 14.9% were severe in patients with RA, PsA and SpA respectively. Patients with low or moderate/high disease were more likely to flare compared to those in remission in patients with RA only (HR: 1.68, 95% CI 1.22-2.31; HR: 2.28, 95% CI 1.50-3.48, respectively). Receiving the Moderna vaccine was associated with a higher HR of flare compared to the Pfizer vaccine in patients with PsA only (HR: 2.21, 95% CI 1.20-4.08). Patients who had two vaccine doses were found to be less likely to flare (HR: 0.08, 95% CI 0.06-0.10). HRs of flares were not significantly different among RA, PsA and SpA. CONCLUSION: About one-fifth of patients experienced a disease flare post COVID-19 mRNA vaccination, but most flares were non-severe. Patients with active disease prior to vaccination should be monitored closely for disease flares, especially in patients with RA.

OBJECTIVES: To evaluate the association between anxiety, depression and resilience with overall health and functioning in axial spondyloarthritis (axSpA). DESIGN: Cross-sectional evaluation of baseline data from a prospective cohort study, with recruitment from January 2018 to March 2021. SETTING: Outpatient clinic in a tertiary hospital in Singapore. PARTICIPANTS: Patients aged 21 years and above who were diagnosed with axSpA. OUTCOME MEASURES: The Hospital Anxiety and Depression Scale (HADS) was used for assessing anxiety and depression, 10-item Connor Davidson Resilience Scale (CD-RISC-10) for resilience, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for disease activity, Bath Ankylosing Spondylitis Functional Index (BASFI) for functional limitation and Assessment of SpondyloArthritis International Society Health Index (ASAS HI) for overall health and functioning. Univariable and multivariable linear regression analyses were performed to assess the association between anxiety, depression and resilience with health and functioning. RESULTS: We included 296 patients in this study. The median (IQR) score for HADS-Anxiety was 5.0 (2.0-8.0), with 13.5% and 13.9% having borderline abnormal and abnormal anxiety, respectively. The median (IQR) score for HADS-Depression was 3.0 (1.0-7.0), with 12.8% and 8.4% having borderline abnormal and abnormal depression, respectively. The median (IQR) CD-RISC-10 score was 29.0 (23.0-32.0) while the median (IQR) ASAS HI score was 4.0 (2.0-7.0). Apart from BASDAI, BASFI and disease duration, anxiety and depression were associated with overall health and functioning (ß: 0.12, 95% CI 0.03, 0.20; ß: 0.20, 95% CI 0.09, 0.31) in the multivariable linear regression. Level of resilience was not associated with health and functioning. CONCLUSION: Anxiety and depression, but not resilience, were associated with poorer health and functioning. Clinicians could consider routinely screening for anxiety and depression in their patients, especially in patients with more severe symptoms.

BACKGROUND: The use of social media in health care may serve as a beneficial tool for education, information dissemination, telemedicine, research, networking, and communications. To better leverage the benefits of social media, it is imperative to understand the patterns of its use and potential barriers to its implementation in health care. A previous study in 2016 that investigated social media use among young clinical rheumatologists (≤45 years) and basic scientists showed that there was substantial social media use among them for social and professional reasons. However, there is a limited inquiry into social media use in different areas of rheumatology, such as spondyloarthritis. OBJECTIVE: We aimed to explore the motivations, barriers, and patterns of social media use among an international group of experts in spondyloarthritis. METHODS: We distributed a web-based survey via email from March 2021 to June 2021 to 198 members of the Assessment of Spondyloarthritis International Society. It contained 24 questions about demographic characteristics, patterns of current social media use, and perceptions of utility. Univariable and multivariable logistic regression analyses were performed to identify the characteristics associated with use trends. RESULTS: The response rate was 78.8% (156/198). Of these, 93.6% (146/156) of participants used at least one social media platform. Apart from internet-based shopping and entertainment, the use of social media for clinical updates (odds ratio [OR] 6.25, 95% CI 2.43-16.03) and research updates (OR 3.45, 95% CI 1.35-8.78) were associated with higher social media consumption. Among the respondents, 66% (103/156) used social media in a work-related manner. The use of social media for new web-based resources (OR 6.55, 95% CI 2.01-21.37), interaction with international colleagues (OR 4.66, 95% CI 1.21-17.90), and establishing a web-based presence (OR 4.05, 95% CI 1.25-13.13) were associated with higher levels of consumption for work-related purposes. Time investment, confidentiality concerns, and security concerns were the top 3 challenges to a wider adoption of social media. CONCLUSIONS: Most respondents (103/156, 66%) use social media in a work-related manner. Professional development, establishing a web-based presence, and international collaboration were associated with higher use. Challenges to social media adoption should be addressed to maximize its benefits.

RESUMO
OBJECTIVE: Health-related quality of life (HRQOL) is an important aspect in the management of chronic diseases such as spondyloarthritis (SpA). A promising approach to reduce respondent burden when measuring HRQOL is the use of shorter patient-reported outcome measures (PROMs) delivered using computerized adaptive tests (CATs). However, the lack of an item bank that covers the entire continuum of the HRQOL domain impedes the development of CATs to measure HRQOL among patients with SpA. We aimed to develop an item bank for an HRQOL measure among patients with SpA based on the items from existing validated PROMs. METHODS: This study is guided by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) and Patient Reported Outcomes Measurement Information System (PROMIS) standards. Relevant articles were retrieved from PubMed, Embase, and PsycINFO (Ovid) databases. Items from existing PROMs were binned and winnowed according to the facets of HRQOL in the World Health Organization (WHO) quality of life framework. RESULTS: We identified 147 relevant articles, from which written permission was obtained for including 31 PROMs into the item bank. PROMs contained 1039 items, which underwent binning and winnowing. This resulted in 968 items covering 23 domains of HRQOL in the WHO framework, with the number of items within each domain ranging from 1 to 453. CONCLUSION: We created an item bank to measure HRQOL among patients with SpA using items from validated PROMs. This set can provide the foundation for the development of CATs to measure HRQOL among patients with SpA.

Evidence indicates that the metabolic inflammation induced by gut microbiota dysbiosis contributes to diabetic kidney disease. Prebiotic supplementations to prevent gut microbiota dysbiosis, inhibit inflammatory responses, and protect the renal function in DKD. Qing-Re-Xiao-Zheng formula (QRXZF) is a Traditional Chinese Medicine (TCM) formula that has been used for DKD treatment in China. Recently, there are growing studies show that regulation of gut microbiota is a potential therapeutic strategy for DKD as it is able to reduce metabolic inflammation associated with DKD. However, it is unknown whether QRXZF is effective for DKD by regulating of gut microbiota. In this study, we investigated the reno-protective effect of QRXZF by exploring its potential mechanism between gut microbiota and downstream inflammatory pathways mediated by gut-derived lipopolysaccharide (LPS) in the kidney. High-fat diet (HFD) and streptozotocin injection-induced DKD mice model was established to assess the QRXZF effect in vivo. Mice treated with QRXZF for 8 weeks had significantly lower levels of urinary albumin, serum cholesterol and triglycerides. The renal injuries observed through histological analysis were attenuated as well. Also, mice in the QRXZF group had higher levels of Zonula occludens protein-1 (ZO-1) expression, lower levels of serum fluorescein-isothiocyanate (FITC)-dextran and less-damaged colonic mucosa as compared to the DKD group, implying the benefit role for the gut barrier integrity. QRXZF treatment also reversed gut dysbiosis and reduced levels of gut-derived LPS. Notably, the expression of toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB), which are important inflammation pathways in DKD, were suppressed in the QRXZF groups. In conclusion, our results indicated that the reno-protective effects of QRXZF was probably associated with modulating gut microbiota and inhibiting inflammatory responses in the kidney.
