Abstract
BACKGROUND Discordance between patient global assessment (PGA) and physician global assessment (PhGA) of rheumatoid arthritis (RA) disease activity is mainly determined by pain and functional disabilities. This study aimed to investigate the shift in PGA-PhGA discordance and the variables associated with future positive discordance (PGA > PhGA) based on the NinJa database in Japan. METHODS We examined 7557 adults with RA registered in both NinJa 2014 and 2018, with a discordance cutoff of 3 on a 10-cm scale. The affected joint distribution was investigated using the joint indices x, y, and z, which were calculated as indices for the upper joint, lower joint, and large joint involvement, respectively. The variables in NinJa 2014 that were associated with positive discordance in NinJa 2018 were examined using binary stepwise logistic regression analysis. RESULTS Due to the small number of patients with RA categorized as having negative discordance (PGA < PhGA), we focused on patients with RA categorized as having either concordance or positive discordance. Logistic regression analysis revealed that positive discordance in NinJa 2018 was associated with age, pain, modified Health Assessment Questionnaire (mHAQ) score, corticosteroid use, and existent positive discordance and was inversely associated with C-reactive protein (CRP) and x at baseline (NinJa 2014). The same findings were observed when patients with RA were divided based on the discordance status at baseline. Persistence (positive discordance to positive discordance) was associated with pain and mHAQ scores but inversely associated with CRP. CONCLUSIONS Positive discordance may persist. Circumventing this requires adequate management of pain and functional impairment.

Abstract
Psoriatic arthritis (PsA) is an inflammatory musculoskeletal disease with a chronic, progressive course. Various aspects of PsA, including its clinical features, disease course and response to treatment, are influenced by sociodemographic characteristics of the patient. This includes patient sex, the biological attributes associated with being male or female, and gender, a sociocultural construct that comprises attitudes, traits and behaviours associated with being a man or a woman. An understanding of sex- and gender-related differences in PsA, as well as their underlying mechanisms, is therefore important for individualized care. In this narrative review, the influence of sex and gender on PsA manifestation and course, patient function and quality of life, and their association with comorbidities are described. Sex- and gender-related disparities in response to advanced therapies and their potential underlying mechanisms are delineated. Differences in pathophysiological mechanisms between male and female patients including genetics, immune and hormonal mechanisms are discussed. Finally, fertility and pregnancy outcomes in PsA are outlined. By adopting sex and gender lenses, this review is aimed at highlighting key differences between male and female patients with PsA and uncovering mechanisms underlying these differences, ultimately promoting individualized care of men and women with PsA and informing future research in this area.

Abstract
ObjectivesTo evaluate the burden of residual disease in patients with axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA) who achieved low disease activity (LDA) status.MethodsWe used baseline data from a clinic registry of SpA in a tertiary hospital in Singapore. For axSpA, LDA was defined as Ankylosing Spondylitis (AS) Disease Activity Score based on erythrocyte sedimentation rate (ASDAS-ESR) < 2.1 or Bath AS Disease Activity Index (BASDAI) < 3/10. For PsA, LDA was defined by achieving 5/7 cutoffs in the minimal disease activity (MDA) or Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) ≤ 13.ResultsIn 262 cases of axSpA (21% women; mean ± standard deviation (SD) age 42 ± 14 yrs), 33% and 43% of patients achieved ASDAS-ESR and BASDAI LDA states, respectively, while in 142 cases of PsA (49% women, mean age 51 ± SD 14 yrs), 35% and 63% achieved MDA and cDAPSA LDA, respectively. Both axSpA and PsA patients with LDA had pain scores ranging from 14.0 to 21.4/100 and fatigue scores ranging from 3.1 to 3.6/10. Substantial burden in physical disability and mental well-being were observed, with low physical and mental component summary scores on the 36-item Short Form Health Survey. AxSpa patients in BASDAI LDA had higher ESR and lower disability than those in ASDAS-ESR LDA. cDAPSA classified nearly twice as many PsA patients into LDA than MDA. Compared to PsA patients in MDA LDA, those in cDAPSA LDA had higher active joint counts, dactylitis, enthesitis, pain scores, and patient global assessment.ConclusionDespite being in LDA, patients with axSpA and PsA experienced substantial residual burden in pain, poorer physical function, and mental well-being.

Abstract
Psoriatic arthritis (PsA) is a seronegative spondyloarthropathy characterized by skin lesions, dactylitis, and enthesitis. Patients with PsA suffer from a variety of psychosocial difficulties and nonspecific symptoms early on in the disease course and continue to experience progressive disease due to delays in diagnosis and treatment. Symptoms initially viewed as somatization could lead to undertreatment and promote psychological distress, poor coping, and negative patient-provider relationships. Pain and fatigue are important complaints that affect the patient's perception and may need to be addressed with a multidisciplinary approach. Maladaptive cognitive responses can lead to a negative illness perception and impact patient beliefs and concerns over treatment, as well as nonadherence. An underlying inflammatory component in affective disorders has been examined, though whether and how it may interact mechanistically in PsA warrants interest. Cognitive behavioral therapy represents a nonpharmacological treatment modality that can be combined with cytokine-targeted therapy to address both somatic and psychological complaints. Future directions for research include: (1) Elucidating nonspecific manifestations (e.g., subclinical stage, differential with functional syndromes) of PsA and how they impact diagnosis and management; (2) characterizing immune-mediated components of mood disorders in PsA; and (3) whether a bidirectional approach with abrogating inflammation and psychotherapeutic support leads to improved outcomes.

Abstract
OBJECTIVE To describe the prevalence of and evaluate the factors associated with fatigue patients with psoriatic arthritis (PsA) in an Asian population. METHODS We used baseline data from a registry of patients with PsA attending an outpatient clinic of a tertiary hospital in Singapore. Demographic data and disease characteristics were evaluated. Fatigue was assessed by question one of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI-F) and the vitality domain of the Medical Outcome Survey, Short-Form 36 (SF-36 VT). We evaluated clusters of variables, and individual variables in association with fatigue. RESULTS We included 131 patients (50.4% men, 63.4% Chinese, median PsA duration 21.0 months) with completed data for fatigue. Forty-five patients (34%) experienced severe fatigue (defined by BASDAI-F > 5/10). We used principal component analysis and identified five clusters of variables that explained 62.9% of the variance of all factors. Of these, disease activity and impact, and disease chronicity were significantly associated with BASDAI-F and SF-36 VT. In multivariable analyses, back pain, peripheral joint pain and patient global assessment were associated with BASDAI-F, whereas peripheral joint pain and mental health were associated with SF-36 VT. CONCLUSION PsA-associated fatigue is prevalent in this Asian PsA cohort and is associated with disease activity, impact and chronicity.

Abstract
Objectives To evaluate factors associated with patient‐physician discordance in a multiethnic Asian cohort of psoriatic arthritis (PsA) patients. Methods We used data from a prospective cohort of consecutive patients with PsA fulfilling the Classification Criteria for Psoriatic Arthritis, recruited from a single center in Singapore. Sociodemographic, clinical data and patient‐reported outcomes were collected using a standardized protocol at baseline, 4 months, 8 months, 1 year, 2 years and 5 years. patient‐physician discordance was defined as patient global assessment minus physician global assessment (PGA‐PhGA). We evaluated variables associated with patient‐physician discordance using generalized linear regression to control for within‐subject effect. Results One hundred and fortytwo patients (51.4% male, 66.2% Chinese, mean [SD] age and duration of illness 51.1 [13.8] years and 27.5 [98.3] months) were recruited at baseline. Paired results for PGA and PhGA were available for 291 visits with median (interquartile range) follow‐up time of 11.6 (17) months. In univariable analysis, duration of illness, fatigue, pain, tender and swollen joint count, dactylitis count, and health‐related quality of life (Short Form‐36) domains were significantly correlated with patient‐physician discordance. In multivariable analysis, age, fatigue level, pain score were positively associated with patient‐physician discordance, while swollen joint count and mental health were negatively associated with patient physician discordance. Conclusions Increased age, higher fatigue levels, higher pain score and poorer mental health may explain underestimation of disease activity by physicians. Physicians’ overestimation of disease activity may be explained by higher swollen joint counts.
