Objective
Environmental factors are of importance for the etiology of rheumatoid arthritis (RA), but much remains unknown concerning the contributions from distinct occupational hazards. We explored the association between occupation and the risk of anti–citrullinated protein antibody (ACPA)+ RA or ACPA? RA.Methods
We analyzed 3,522 cases and 5,580 controls from the Swedish population–based Epidemiological Investigation of Rheumatoid Arthritis case–control study. A questionnaire was used to obtain information on work history and lifestyle factors. Blood samples were drawn for serologic analyses. Unconditional logistic regression was used to calculate the odds ratio (OR) of RA associated with the last occupation before study inclusion. Analyses were performed with adjustments for known environmental exposures and lifestyle factors, including pack‐years of cigarette smoking, alcohol use, body mass index, and education.Results
Among men, bricklayers and concrete workers (OR 2.9, 95% confidence interval [95% CI] 1.4–5.7), material handling operators (OR 2.4, 95% CI 1.3–4.4), and electrical and electronics workers (OR 2.1, 95% CI 1.1–3.8) had an increased risk of ACPA+ RA. For ACPA? RA, bricklayers and concrete workers (OR 2.4, 95% CI 1.0–5.7) and electrical and electronics workers (OR 2.6, 95% CI 1.3–5.0) had an increased risk. Among women, assistant nurses and attendants had a moderately increased risk of ACPA+ RA (OR 1.3, 95% CI 1.1–1.6). No occupations were significantly associated with ACPA? RA among women.Conclusion
Mainly occupations related to potential noxious airborne agents were associated with an increased risk of ACPA+ or ACPA? RA, after adjustments for previously known confounders.2.

Objective
In real life, in a substantial proportion of gouty patients receiving urate‐lowering therapy (ULT), urate levels are not maintained below the target of 6.0 mg/dl. We aimed to search for factors associated with poor control of serum uric acid (UA) levels in a large population of patients with gout receiving ULT.Methods
This cross‐sectional study involved adults with gout in primary care who were receiving ULT. Demographics, gout history, comorbidities, lifestyle, clinical factors, concomitant treatments, and laboratory data were compared in well‐controlled gout (serum UA ≤6.0 mg/dl) versus poorly controlled gout (serum UA >6.0 mg/dl) on univariate and multivariate analyses.Results
Among the 1,995 patients receiving ULT, only 445 (22.3%) had reached the target of 6.0 mg/dl serum UA. Such patients had a lower rate of gout flares within the previous year than patients without the target (mean ± SD 1.7 ± 1.4 versus 2.1 ± 1.4; P < 0.0001). The main factors associated with poor serum UA level control in multivariate analysis were low high‐density lipoprotein cholesterol level (adjusted odds ratio [OR] 0.5 [95% confidence interval (95% CI) 0.26–0.96]; P = 0.04), high total cholesterol level (OR 1.83 [95% CI 1.29–2.60]; P = 0.0007), increased waist circumference (OR 1.55 [95% CI 1.11–2.13]; P = 0.008), and alcohol consumption (OR 1.52 [95% CI 1.15–2.00]; P = 0.003).Conclusion
Dyslipidemia, abdominal obesity, and alcohol consumption are the main factors associated with a poor response to ULT. Knowledge of these factors might help physicians identify cases of gout that may be less likely to achieve target urate level.3.

Objective
The optimal timing of tumor necrosis factor antagonists before elective surgery is unknown. This study evaluated the association between infliximab timing and serious infection after elective hip or knee arthroplasty.Methods
A retrospective cohort study evaluated US Medicare patients with rheumatoid arthritis, inflammatory bowel disease, psoriasis, psoriatic arthritis, or ankylosing spondylitis who received infliximab within 6 months of elective knee or hip arthroplasty from 2007 to 2013. Propensity‐adjusted analyses examined whether infliximab stop timing (time between the most recent infusion and surgery) was associated with hospitalized infection within 30 days or prosthetic joint infection (PJI ) within 1 year.Results
Hospitalized infection within 30 days occurred after 270 of 4,288 surgeries (6.3%). Infliximab stop timing <4 weeks versus 8–12 weeks was not associated with an increase in infection within 30 days (propensity‐adjusted odds ratio [OR ] 0.90 [95% confidence interval (95% CI ) 0.60–1.34]). The rate of PJI was 2.9 per 100 person‐years and was not increased in patients with stop timing <4 weeks versus 8–12 weeks (hazard ratio [HR ] 0.98 [95% CI 0.52–1.87]). Glucocorticoid dosage >10 mg/day was associated with increased risk of 30‐day infection (OR 2.11 [95% CI 1.30–3.40]) and PJI (HR 2.70 [95% CI 1.30–5.60]). Other risk factors for infection included elderly age, comorbidities, revision surgery, and previous hospitalized infection.Conclusion
Administering infliximab within 4 weeks of elective knee or hip arthroplasty was not associated with a higher risk of short‐ or long‐term serious infection compared to withholding infliximab for longer time periods. Glucocorticoid use, especially >10 mg/day, was associated with an increased infection risk.4.

Objective
To explore whether metabolic syndrome and its components are associated with hand osteoarthritis (OA) using longitudinal data from the Framingham Study.Methods
Our cross‐sectional analyses included 1,089 persons (ages 50–75 years), of whom 785 had longitudinal radiographs obtained 7 years apart. Of these, 586 with no hand OA at baseline were included in analyses of hand OA incidence. We explored associations between metabolic syndrome and its components (central obesity, hypertension, diabetes mellitus, triglyceridemia, and low high‐density lipoprotein) and radiographic hand OA (defined as ≥2 interphalangeal joints with a Kellgren/Lawrence [K/L] grade of ≥2) using logistic regression analyses with adjustment for age, sex, and body mass index. In longitudinal analyses, metabolic syndrome was used as a predictor for change in K/L sum score and incident hand OA.Results
Metabolic syndrome was not associated with the presence of hand OA (odds ratio [OR] 1.11 [95% confidence interval (95% CI) 0.78–1.59]), change in K/L sum score (OR 0.83 [95% CI 0.59–1.17]), or incidence of hand OA (OR 0.91 [95% CI 0.58–1.44]). Hypertension was borderline significantly associated with the presence of hand OA (OR 1.25 [95% CI 0.90–1.74]), and a significant association was found between hypertension and change in K/L sum score (OR 1.47 [95% CI 1.08–1.99]). Consistent dose‐response relationships were not demonstrated (data not shown). Furthermore, hypertension was not significantly associated with hand OA incidence (OR 1.23 [95% CI 0.82–1.83]). No significant associations were found between metabolic syndrome and erosive hand OA.Conclusion
We found no association between metabolic syndrome and hand OA. The role of hypertension in hand OA pathogenesis warrants further investigation.5.

Objective
A subset of patients with systemic sclerosis (SSc) develop severe gastrointestinal (GI) dysmotility. We sought to determine predictors of severe SSc GI dysmotility and to identify distinct features associated with this phenotype.Methods
Patients with SSc who required supplemental nutrition (enteral or parenteral tube feeding) were compared to SSc patients with mild GI symptoms in a cross‐sectional analysis. The association between severe GI dysmotility and clinical and serologic features was examined using logistic regression. Baseline data were examined to determine predictors of developing severe GI dysfunction using Cox regression.Results
SSc patients with severe GI dysmotility (n = 66) were more likely than those patients with mild GI symptoms (n = 1,736) to be male (odds ratio [OR] 2.47 [95% confidence interval (95% CI) 1.34–4.56]; P = 0.004), and to have myopathy (OR 5.53 [95% CI 2.82–10.82]; P < 0.001), and sicca symptoms (OR 2.40 [95% CI 1.30–4.42]; P = 0.005), even after adjustment for potential confounders. Baseline features that were associated with the future development of severe GI dysfunction included male sex (hazard ratio [HR] 2.99 [95% CI 1.53–5.84]; P = 0.001) and myopathy (HR 5.08 [95% CI 2.21–11.67]; P < 0.001).Conclusion
Distinct clinical features are present in SSc patients who are at risk of developing severe GI dysmotility. This finding is not only important clinically but also suggests that a unique pathologic process is at work in these patients.6.

Objective
To assess whether more frequent fish consumption is associated with lower rheumatoid arthritis (RA) disease activity scores among participants in an RA cohort.Methods
We conducted a cross‐sectional analysis using baseline data from participants in the Evaluation of Subclinical Cardiovascular Disease and Predictors of Events in Rheumatoid Arthritis cohort study. Frequency of fish consumption was assessed by a baseline food frequency questionnaire assessing usual diet in the past year. Multivariable, total energy–adjusted linear regression models provided effect estimates and 95% confidence intervals (95% CIs) for frequency of fish consumption (i.e., never to <1 time/month, 1 time/month to <1 time/week, 1 time/week, and ≥2 times/week) on baseline Disease Activity Score in 28 joints (DAS28) using the C‐reactive protein (CRP) level. We also estimated the difference in DAS28‐CRP associated with increasing fish consumption by 1 serving per week.Results
Among 176 participants, the median DAS28‐CRP score was 3.5 (interquartile range 2.9–4.3). In an adjusted linear regression model, subjects consuming fish ≥2 times/week had a significantly lower DAS28‐CRP compared with subjects who ate fish never to <1 time/month (difference ?0.49 [95% CI ?0.97, ?0.02]). For each additional serving of fish per week, DAS28‐CRP was significantly reduced by 0.18 (95% CI ?0.35, ?0.004).Conclusion
Our findings suggest that higher intake of fish may be associated with lower disease activity in RA patients.7.

Objective
Rheumatoid arthritis (RA) is a morbid, mortal, and costly condition without a cure. Treatments for RA have expanded over the last 2 decades, and direct medical costs may differ by types of treatments. There has not been a systematic literature review since the introduction of new RA treatments, including biologic disease‐modifying antirheumatic drugs (bDMARDs).Methods
We conducted a systematic literature review with meta‐analysis of direct medical costs associated with RA patients cared for in the US since the marketing of the first bDMARD. Standard search strategies and sources were used, and data were extracted independently by 2 reviewers. The methods and quality of included studies were assessed. Total direct medical costs as well as RA‐specific costs were calculated using random‐effects meta‐analysis. Subgroups of interest included Medicare patients and those using bDMARDs.Results
We found 541 potentially relevant studies, and 12 articles met the selection criteria. The quality of studies varied: one‐third were poor, one‐third were fair, and one‐third were good. Total direct medical costs were estimated at $12,509 (95% confidence interval [95% CI] 7,451–21,001) for all RA patients using any treatment regimen and $36,053 (95% CI 32,138–40,445) for bDMARD users. RA‐specific costs were $3,723 (95% CI 2,408–5,762) for all RA patients using any treatment regimen and $20,262 (95% CI 17,480–23,487) for bDMARD users.Conclusion
The total and disease‐specific direct medical costs for patients with RA is substantial. Among bDMARD users, the cost of RA care is more than half of all direct medical costs.8.

Objective
To examine the frequency of and factors associated with fear of movement (FOM ) among patients with symptomatic knee osteoarthritis (KOA ), using the new Brief Fear of Movement (BFOM ) measure.Methods
Participants (n = 350) enrolled in a clinical trial completed the BFOM scale prior to randomization. The relationships of BFOM with the following characteristics were examined: age, sex, race, education, pain and activities of daily living (ADL ) subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS ), knee symptom duration, depressive symptoms (8‐item Patient Health Questionnaire [PHQ ‐8]), history of falls and knee injury, family history of knee problems, self‐efficacy for exercise (SEE ), and unilateral balance test. A proportional odds logistic regression model examined multivariable associations of participant characteristics with a 3‐level BFOM variable (agreement with 0, 1–2, or ≥3 items).Results
The majority of participants (77%) agreed with at least 1 item on the BFOM scale, and 36% endorsed 3+ items, suggesting a high degree of FOM . In the multivariable model, the following remained significant after backward selection: age (odds ratio [OR ] 0.79 per 10‐point increase, 95% confidence interval [95% CI ] 0.66–0.95), KOOS ADL (OR 0.86 per 10‐point increase, 95% CI 0.76–0.97), PHQ ‐8 (OR 1.15, 95% CI 1.08–1.22), and SEE (OR 0.87 per 10‐point increase, 95% CI 0.78–0.96).Conclusion
FOM was common among patients with symptomatic KOA , and this could negatively impact physical activity. Psychological variables were significantly associated with FOM , suggesting behavioral and psychological interventions may decrease FOM and improve outcomes among individuals with symptomatic KOA .9.

Objective
To assess hepatitis B virus (HBV) reactivation rates in patients with resolved or chronic HBV infection, receiving disease‐modifying antirheumatic drugs (DMARDs) and with or without antiviral prophylaxis.Methods
We conducted a systematic review and meta‐analysis. Electronic searches were conducted in PubMed, Medline, and Embase using Ovid through December 31, 2015. A search strategy was developed for each database using the following inclusion criteria: for participants, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and resolved or chronic HBV infection; for intervention, tumor necrosis factor (TNF) inhibitors or non‐TNF biologic or nonbiologic DMARDs; and for outcome, HBV reactivation. Four reviewers independently extracted study data and assessed study quality using the Newcastle‐Ottawa Scale. To determine the pooled HBV reactivation rate, the variances of the raw proportions were stabilized using a Freeman‐Tukey‐type arcsine square root transformation, using a random‐effects model.Results
Twenty‐five studies met the inclusion criteria. The overall pooled rate of HBV reactivation was 1.6% (95% confidence interval [95% CI] 0.8–2.6) in patients with resolved HBV. Similar rates were observed in resolved patients taking TNF inhibitors (1.4% [95% CI 0.5–2.6]), non‐TNF biologics (6.1% [95% CI 0.0–16.6]), and nonbiologic DMARDs (1.7% [95% CI 0.2–4.2]). We also found that the reactivation rate was lower in patients with chronic HBV infection who received antiviral prophylaxis (9.0% [95% CI 4.1–15.5]) than in those who did not (14.6% [95% CI 4.3–29.0]).Conclusion
We found that the HBV reactivation rate in inflammatory arthritis patients receiving DMARDs was low in resolved patients and moderate in patients with chronic HBV infection. Further, lower rates were observed in patients with chronic HBV infection who were using antiviral prophylaxis.10.

Objective
To determine the prevalence of lower urinary tract symptoms (LUTS) in systemic sclerosis (SSc), to find specific risk factors, and to assess their impact on quality of life (QoL).Methods
In a multicenter study, 334 patients completed a self‐administered questionnaire on LUTS and QoL. LUTS were classified into 3 main categories: storage, voiding, and post‐micturition symptoms. Digestive symptoms burden was captured by a visual analog scale, divided into 5 equal categories. Multivariable logistic regressions were performed to test association between risk factors and LUTS categories. Linear regression adjusted the association between LUTS and QoL.Results
LUTS were recorded in 311 SSc patients (96.0%) and classified as severe in 120 (38.0%). The storage category of LUTS was the most prevalent (91.9%), followed by voiding (72.2%) and then by post‐micturition symptoms (49.8%). Risk factors identified in the multivariable models were higher than the median Health Assessment Questionnaire disability index (HAQ DI; odds ratio [OR] 4.2 [95% confidence interval (95% CI) 1.4–12.9]) in the storage category; higher than the median HAQ DI (OR 2.4 [95% CI 1.2–4.9]) for digestive symptoms burden (OR 1.9 [95% CI 1.3–2.7]) and synovitis (OR 4.8 [95% CI 1.0–22.6) in the voiding category; and higher for digestive symptoms burden (OR 1.2 [95% CI 1.0–1.5]) in the post‐micturition category of symptoms. These factors also increased the odds of having further severe symptoms. QoL was affected by the 3 categories of LUTS and decreased progressively with increasing frequency of symptoms.Conclusion
Self‐reported LUTS are among the most frequent symptoms in SSc and are associated with digestive symptoms. SSc patients with LUTS have lower QoL.11.

Objective
To profile osteoporosis (OP) care in patients with rheumatoid arthritis (RA) over the past decade.Methods
Patients with RA or osteoarthritis (OA) were followed from 2003 through 2014. OP care was defined as receipt of OP treatment (with the exception of calcium/vitamin D) or screening (OPTS). Adjusted trends over followup, and the factors associated with OP care, were examined using multivariable Cox proportional hazards.Results
OPTS was reported in 67.4% of 11,669 RA patients and in 64.6% of 2,829 OA patients during a median (interquartile range) 5.5 (2–9) years of followup. In patients for whom treatment was recommended by the 2010 American College of Rheumatology (ACR) glucocorticoid‐induced OP (GIOP) guidelines (48.4% of RA patients and 17.6% of OA patients), approximately 55% overall reported OP medication use. RA patients were not more likely to undergo OPTS compared to OA patients (hazard ratio 1.04 [95% confidence interval 0.94–1.15]). Adjusted models showed a stable trend for OPTS between 2004 and 2008 compared to 2003, with a significant downward trend after 2008 in both RA and OA patients. Factors associated with receipt of OP care in RA patients were older age, postmenopausal state, prior fragility fracture or diagnosis of OP, any duration of glucocorticoid treatment, and use of biologic agents.Conclusion
Approximately half of RA patients for whom treatment was indicated never received an OP medication. OP care in RA patients was not better than in OA patients, and the relative risk of the application of this care has been decreasing in RA and OA patients since 2008 without improvement after the release of the 2010 ACR GIOP guideline.12.

Objective
We examined rates of adverse pregnancy outcomes (APO) by race/ethnicity among women with systemic lupus erythematosus (SLE), with and without antiphospholipid antibodies (aPL), and whether socioeconomic status (SES) accounted for differences.Methods
Data were from the PROMISSE (Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Antibody Syndrome and Systemic Lupus Erythematosus) study, a multicenter study that enrolled 346 patients with SLE and 62 patients with SLE and aPL (50% white, 20% African American, 17% Hispanic, 12% Asian/Pacific Islander). Measures of SES were educational attainment, median community income, and community education. Logistic regression analyses were conducted to determine odds of APO for each racial/ethnic group, controlling first for age and clinical variables, and then for SES.Results
The frequency of APO in white women with SLE, with and without aPL, was 29% and 11%, respectively. For African American and Hispanic women it was approximately 2‐fold greater. In African American women with SLE alone, adjustment for clinical variables attenuated the odds ratio (OR) from 2.7 (95% confidence interval [95% CI] 1.3–5.5) to 2.3 (95% CI 1.1–5.1), and after additional adjustment for SES, there were no longer significant differences in APO compared to whites. In contrast, in SLE patients with aPL, whites, African Americans, and Hispanics had markedly higher risks of APO compared to white SLE patients without aPL (OR 3.5 [95% CI 1.4–7.7], OR 12.4 [95% CI 1.9–79.8], and OR 10.4 [95% CI 2.5–42.4], respectively), which were not accounted for by clinical or SES covariates.Conclusion
This finding suggests that for African American women with SLE without aPL, SES factors are key contributors to disparities in APO, despite monthly care from experts, whereas other factors contribute to disparities in SLE with aPL.13.

Objective
To investigate associations of body mass index (BMI), waist circumference (WC), and waist/hip ratio (WHR) with survival to age 85 years with mobility limitation or death before age 85 years among older women with total knee replacement (TKR) or total hip replacement (THR) for osteoarthritis (OA).Methods
This was a prospective study of women (ages 65–79 years at baseline) from the Women's Health Initiative, recruited during 1993–1998 and followed through 2012. Women's Health Initiative data were linked to Medicare claims data to determine TKR (n = 1,867) and THR (n = 944) for OA. Women were followed for up to 18 years after undergoing THR or TKR to determine mobility status at age 85 years.Results
Compared with normal‐weight women, overweight, obese I, and obese II women with THR had significantly increased risk of survival to age 85 years with mobility limitation (P < 0.001 for linear trend), with the strongest risk among obese II women (odds ratio [OR] 4.37 [95% confidence interval (95% CI) 1.96–9.74]). Obese II women with THR also had increased risk of death before age 85 years. Women with THR and WC >88 cm relative to ≤88 cm had increased risk of survival to age 85 years with mobility limitation (OR 1.65 [95% CI 1.17–2.33]) but not death before age 85 years. High BMI, WC, and WHR were associated with significantly increased risk of late‐life mobility limitation and death among women with TKR for OA.Conclusion
Among older women who underwent THR or TKR for OA, baseline general and abdominal obesity were associated with increased risk of late‐life mobility limitation.14.

Objective
Objective measures of function are important in rheumatoid arthritis (RA). The objective of this study was to investigate grip strength in patients with early RA.Methods
An inception cohort of 225 patients with early RA was followed in accordance with a structured protocol. Average and peak grip force values of the dominant hand (measured using a Grippit device [AB Detektor]) were evaluated and compared to expected age‐ and sex‐specific reference values from the literature. Separate analyses were performed for those with limited self‐reported disability (Health Assessment Questionnaire disability index [HAQ DI] score ≤0.5) and clinical remission (Disease Activity Score in 28 joints <2.6).Results
Baseline average grip force among RA patients was significantly lower than the corresponding expected value (mean 105N versus 266N; P < 0.001). Observed average and peak grip force values were significantly reduced compared to those expected in women as well as in men over time and at all time points. The average grip force improved significantly from inclusion to the 12‐month visit (age‐corrected mean change 34N [95% confidence interval 26–43]). At 5 years, the average grip force was still lower than that expected overall (mean 139N versus 244N; P < 0.001), and also among those with HAQ DI scores ≤0.5 and those in clinical remission.Conclusion
Grip strength improved in early RA patients, particularly during the first year. However, it was still significantly impaired 5 years after diagnosis, even among those with limited self‐reported disability and those in clinical remission. This suggests that further efforts to improve hand function are important in early RA.15.

Objective
To investigate whether associations between pain and the additional symptoms associated with fibromyalgia are different in persons with chronic widespread pain (CWP ) compared to multisite pain (MSP ), with or without joint areas.Methods
Six studies were used: 1958 British birth cohort, Epidemiology of Functional Disorders, Kid Low Back Pain, Managing Unexplained Symptoms (Chronic Widespread Pain) in Primary Care: Involving Traditional and Accessible New Approaches, Study of Health and its Management, and Women's Health Study (WHEST ; females). MSP was defined as the presence of pain in ≥8 body sites in adults (≥10 sites in children) indicated on 4‐view body manikins, conducted first to include joints (positive joints) and second without (negative joints). The relationship between pain and fatigue, sleep disturbance, somatic symptoms, and mood impairment was assessed using logistic regression. Results are presented as odds ratios (OR s) with 95% confidence intervals (95% CI s).Results
There were 34,818 participants across the study populations (adults age range 42–56 years, male 43–51% [excluding WHEST ], and CWP prevalence 12–17%). Among those reporting MSP , the proportion reporting CWP ranged between 62% and 76%. Among those reporting the symptoms associated with fibromyalgia, there was an increased likelihood of reporting pain, the magnitude of which was similar regardless of the definition used. For example, within WHEST , reporting moderate/severe fatigue (Chalder fatigue scale 4–11) was associated with a >5‐fold increase in likelihood of reporting pain (CWP OR 5.2 [95% CI 3.9–6.9], MSP –positive joints OR 6.5 [95% CI 5.0–8.6], and MSP –negative joints OR 6.5 [95% CI 4.7–9.0]).Conclusion
This large‐scale study demonstrates that regardless of the pain definition used, the magnitude of association between pain and other associated symptoms of fibromyalgia is similar. This finding supports the continued collection of both when classifying fibromyalgia, but highlights the fact that pain may not require to follow the definition outlined within the 1990 American College of Rheumatology criteria.16.

Objective
Obesity is implicated in rheumatoid arthritis (RA) development, severity, outcomes, and treatment response. We estimated the independent effects of overweight and obesity on ability to achieve sustained remission (sREM) in the 3 years following RA diagnosis.Methods
Data were from the Canadian Early Arthritis Cohort, a multicenter observational trial of early RA patients treated by rheumatologists using guideline‐based care. sREM was defined as Disease Activity Score in 28 joints (DAS28) <2.6 for 2 consecutive visits. Patients were stratified by body mass index (BMI) as healthy (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2), and obese (≥30 kg/m2). Cox regression was used to estimate the effect of the BMI category on the probability of achieving sREM over the first 3 years, controlling for age, sex, race, education, RA duration, smoking status, comorbidities, baseline DAS28, Health Assessment Questionnaire disability index, C‐reactive protein level, and initial treatment.Results
Of 982 patients, 315 (32%) had a healthy BMI, 343 (35%) were overweight, and 324 (33%) were obese; 355 (36%) achieved sREM within 3 years. Initial treatment did not differ by BMI category. Compared to healthy BMI, overweight patients (hazard ratio [HR] 0.75 [95% confidence interval (95% CI) 0.58–0.98]) and obese patients (HR 0.53 [95% CI 0.39–0.71]) were significantly less likely to achieve sREM.Conclusion
Rates of overweight and obesity were high (69%) in this early RA cohort. Overweight patients were 25% less likely, and obese patients were 47% less likely, to achieve sREM in the first 3 years, despite similar initial disease‐modifying antirheumatic drug treatment and subsequent biologic use. This is the largest study demonstrating the negative impact of excess weight on RA disease activity and supports a call to action to better identify and address this risk in RA patients.18.

Objective
To investigate demographic, symptom‐related, and cognitive determinants of cane use for knee osteoarthritis (OA) and prioritize the factors that could facilitate cane use in people with no previous cane use.Methods
A survey of people ages ≥45 years with a clinical diagnosis of knee OA was conducted. The survey consisted of the following two sections: 1) demographic and cognitive determinants of cane use assessed via subscales of the Cane Cognitive Mediator Scale, and 2) 19 statements, underpinned by the Behaviour Change Wheel theoretical framework, relating to factors that could facilitate regular cane use. Logistic regression was used to examine determinants of cane use, while a priority pairwise ranking activity (1000minds software) determined the rank order of the 19 statements that could facilitate cane use.Results
A total of 529 people completed Part 1 (80% females; 35% cane users) and 231 people completed Part 2. Age (odds ratio [OR] 1.06, 95% confidence interval [95% CI] 1.03– 1.09), body mass index (BMI) (OR 1.03, 95% CI 1.01–1.06), knee pain ≥3 years (OR 2.62, 95% CI 1.63–4.21) and numeric rating scale pain level while walking (OR 1.19, 95% CI 1.09–1.30) were significant independent determinants of cane use. In people who had never used a cane, statements relating to cane‐use technique, fitting, knowledge of benefits, and motivation were ranked highest overall.Conclusion
Independent determinants of cane use include older age, higher BMI, greater pain duration, and greater severity of knee pain. Strategies targeting an individual's capability and motivation to use a cane may increase cane use among people with knee OA.19.

Objective
To compare microvascular damages on nailfold capillaroscopy (NFC) with macrovascular manifestations evaluated by hand power Doppler ultrasonography (PDUS) in systemic sclerosis (SSc) patients, and to assess the associations of these damages with the main digital manifestations of the disease: digital ulcers, acroosteolysis, and calcinosis.Methods
NFC, hand radiographs, and PDUS were systematically performed in 64 unselected SSc patients. PDUS evaluation with assessment of ulnar artery occlusion (UAO) and finger pulp blood flow (FPBF) were performed blinded for the results of radiographs and NFC.Results
UAO and pathologic FPBF were associated with severe capillary loss (<4 capillaries/mm) on NFC (odds ratio [OR] 4.04 [95% confidence interval (95% CI) 1.23–13.29]; P < 0.05, and OR 3.38 [95% CI 1.03–11.05]; P < 0.05, respectively). Digital ulcer history was associated with UAO (OR 10.71 [95% CI 3.36–34.13]; P < 0.0001), pathologic FPBF (OR 7.67 [95% CI 2.52–23.28]; P < 0.0001), late NFC pattern (OR 6.33 [95% CI 2.03–19.68]; P = 0.001), and severe capillary loss (OR 8.52 [95% CI 2.15–33.78]; P = 0.001). Acroosteolysis was also associated with UAO (OR 15.83 [95% CI 3.95–63.54]; P < 0.0001), pathologic FPBF (OR 5.52 [95% CI 1.71–17.90]; P = 0.003), late NFC pattern (OR 6.86 [95% CI 2.18–21.53]; P = 0.001), and severe capillary loss (OR 7.20 [95% CI 2.16–24.02]; P = 0.001). Calcinosis on radiographs was associated with late NFC pattern (OR 5.41 [95% CI 1.82–16.12]; P = 0.002), severe capillary loss (OR 12.69 [95% CI 3.14–51.26]; P < 0.0001), and UAO (OR 3.19 [95% CI 1.14–8.92]; P = 0.025). Combination of UAO and severe capillary loss in the same patient was especially associated with digital ulcer history (OR 18.60 [95% CI 2.24–154.34]; P = 0.001) and acroosteolysis (OR 10.83 [95% CI 2.56–45.88]; P = 0.001).Conclusion
Microvascular damages evaluated by NFC and macrovascular features like UAO assessed by PDUS show concordant associations with the main digital manifestations of the disease.20.
