Interpersonal Process of Dyadic Coping in Rheumatoid Arthritis: A Perspective From the Australian Rheumatology Association Database.

OBJECTIVE: Dyadic coping, the process of coping that transpires between couples challenged by one partner's illness, is an important predictor of disease adjustment and patient well-being. However, the extent of dyadic coping in rheumatoid arthritis (RA) remains unclear. This study examines the effect of dyadic coping on psychological distress and relationship quality from the perspectives of both participants with RA and their spouses. METHODS: Participants and their spouses were invited to participate in an online survey study if they were aged ≥ 18 years and had lived together for more than a year. The survey included the Chronic Pain Grade Scale, Dyadic Coping Inventory, Depression Anxiety Stress Scale, and Dyadic Adjustment Scale. Participants and spouses completed the survey independently. The actor-partner interdependence model was used to analyze the dyadic data. RESULTS: One hundred sixty-three couples participated. Our findings showed that participants who reported higher supportive dyadic coping reported lower depression, anxiety, and stress, and higher relationship quality, whereas participants who reported higher negative dyadic coping reported higher depression, anxiety, and stress, and lower relationship quality. Spouses who reported higher supportive dyadic coping reported higher relationship quality, but no effect on depression, anxiety, and stress was observed. In contrast, spouses who reported higher negative dyadic coping reported higher levels of depression, anxiety, and stress, and lower relationship quality. CONCLUSION: Participants' and spouses' perceptions of supportive and negative dyadic coping closely influenced their psychological distress and relationship quality. Further, having a partner with RA also seemed to affect the spouse, especially when there was a negative dyadic coping pattern.

Methotrexate for juvenile idiopathic arthritis.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. Methotrexate has broad immunomodulatory properties and is the most commonly used disease-modifying antirheumatic drug (DMARD). This is an update of a 2001 Cochrane review. It supports a living guideline for children and young people with JIA. OBJECTIVES: To assess the benefits and harms of methotrexate for children and young people with juvenile idiopathic arthritis. SEARCH METHODS: The Australian JIA Living Guideline Working Group created a registry of all randomised controlled trials (RCTs) of JIA by searching CENTRAL, MEDLINE, Embase, and trials registries. The date of the most recent search of online databases was 1 February 2023. SELECTION CRITERIA: We searched for RCTs that compared methotrexate with placebo, no treatment, or another DMARD (with or without concomitant therapies) in children and young people (aged up to 18 years) with JIA. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. The main comparison was methotrexate versus placebo. Our outcomes were treatment response, sustained clinically inactive disease, function, pain, participant global assessment of well-being, serious adverse events, and withdrawals due to adverse events. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We identified three new trials in this update, bringing the total number of included RCTs to five (575 participants). Three trials evaluated oral methotrexate versus placebo, one evaluated methotrexate plus intra-articular glucocorticoid (IAGC) therapy versus IAGC therapy alone, and one evaluated methotrexate versus leflunomide. Doses of methotrexate ranged from 5 mg/m2/week to 15 mg/m2/week in four trials, and participants in the methotrexate group of the remaining trial received 0.5 mg/kg/week. Trial size varied from 31 to 226 participants. The average age of participants ranged from four to 10 years. Most participants were females and most had nonsystemic JIA. The study that evaluated methotrexate plus IAGC therapy versus IAGC therapy alone recruited children and young people with the oligoarticular disease subtype of JIA. Two placebo-controlled trials and the trial of methotrexate versus leflunomide were adequately randomised and blinded, and likely not susceptible to important biases. One placebo-controlled trial may have been susceptible to selection bias due to lack of adequate reporting of randomisation methods. The trial investigating the addition of methotrexate to IAGC therapy was susceptible to performance and detection biases. Methotrexate versus placebo Methotrexate compared with placebo may increase the number of children and young people who achieve treatment response up to six months (absolute difference of 163 more per 1000 people; risk ratio (RR) 1.67, 95% confidence interval (CI) 1.21 to 2.31; I2 = 0%; 3 trials, 328 participants; low-certainty evidence). However, methotrexate compared with placebo may have little or no effect on pain as measured on an increasing scale of 0 to 100 (mean difference (MD) -1.10 points, 95% CI -9.09 to 6.88; 1 trial, 114 participants), improvement in participant global assessment of well-being (absolute difference of 92 more per 1000 people; RR 1.23, 95% CI 0.88 to 1.72; 1 trial, 176 participants), occurrence of serious adverse events (absolute difference of 5 fewer per 1000 people; RR 0.63, 95% CI 0.04 to 8.97; 3 trials, 328 participants), and withdrawals due to adverse events (RR 3.46, 95% CI 0.60 to 19.79; 3 trials, 328 participants) up to six months. We could not estimate the absolute difference for withdrawals due to adverse events because there were no withdrawals in the placebo group. All outcomes were reported within six months of randomisation. We downgraded the certainty of the evidence to low for all outcomes due to indirectness (suboptimal dosing of methotrexate and diverse outcome measures) and imprecision (few participants and low event rates). No trials reported function or the number of participants with sustained clinically inactive disease. Serious adverse events included liver derangement, abdominal pain, and inadvertent overdose. Methotrexate plus intra-articular corticosteroid therapy versus intra-articular corticosteroid therapy alone Methotrexate plus IAGC therapy compared with IAGC therapy alone may have little or no effect on the probability of sustained clinically inactive disease or the rate of withdrawals due to adverse events up to 12 months in children and young people with the oligoarticular subtype of JIA (low-certainty evidence). We could not calculate the absolute difference in withdrawals due to adverse events because there were no withdrawals in the control group. We are uncertain if there is any difference between the interventions in the risk of severe adverse events, because none were reported. The study did not report treatment response, function, pain, or participant global assessment of well-being. Methotrexate versus an alternative disease-modifying antirheumatic drug Methotrexate compared with leflunomide may have little or no effect on the probability of treatment response or on function, participant global assessment of well-being, risk of serious adverse events, and rate of withdrawals due to adverse events up to four months. We downgraded the certainty of the evidence for all outcomes to low due to imprecision. The study did not report pain or sustained clinically inactive disease. AUTHORS' CONCLUSIONS: Oral methotrexate (5 mg/m2/week to 15 mg/m2/week) compared with placebo may increase the number of children and young people achieving treatment response but may have little or no effect on pain or participant global assessment of well-being. Oral methotrexate plus IAGC injections compared to IAGC injections alone may have little or no effect on the likelihood of sustained clinically inactive disease among children and young people with oligoarticular JIA. Similarly, methotrexate compared with leflunomide may have little or no effect on treatment response, function, and participant global assessment of well-being. Serious adverse events due to methotrexate appear to be rare. We will update this review as new evidence becomes available to inform the living guideline.

Australian recommendations on perioperative use of disease-modifying anti-rheumatic drugs in people with inflammatory arthritis undergoing elective surgery.

Disease-modifying anti-rheumatic drugs (DMARDs) are effective treatments for inflammatory arthritis but carry an increased risk of infection. For patients undergoing surgery, there is a need to consider the trade-off between a theoretical increased risk of infection with continuation of DMARDs perioperatively versus an increased risk of disease flare if they are temporarily withheld. We used the Grading of Recommendations Assessment, Development and Evaluation methodology to develop recommendations for perioperative use of DMARDs for people with inflammatory arthritis undergoing elective surgery. The recommendations form part of the National Health and Medical Research Council-endorsed Australian Living Guideline for the Pharmacological Management of Inflammatory Arthritis. Conditional recommendations were made against routinely discontinuing conventional synthetic and biologic (b) DMARDs in the perioperative period but to consider temporary discontinuation of bDMARDs in individuals with a high risk of infection or where the impact of infection would be severe. A conditional recommendation was made in favour of temporary discontinuation of targeted synthetic DMARDs in the perioperative period.

Australian recommendations on tapering of biologic and targeted synthetic disease-modifying anti-rheumatic drugs in inflammatory arthritis.

Biological and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARD) have been an important advance in the management of inflammatory arthritis, but are expensive medications, carry a risk of infection and other adverse effects, and are often perceived as a burden by patients. We used GRADE methodology to develop recommendations for dose reduction and discontinuation of b/tsDMARD in people with rheumatoid arthritis (RA), axial spondyloarthritis (AxSpA) and psoriatic arthritis (PsA) who have achieved a low disease activity state or remission. The recommendations form part of the Australian Living Guideline for the Pharmacological Management of Inflammatory Arthritis, an NHMRC-endorsed 'living' guideline, in which recommendations are updated in near real-time as new evidence emerges. Conditional recommendations were made in favour of dose reduction in RA and AxSpA but not in PsA. Abrupt discontinuation of b/tsDMARD is not recommended in any of the three diseases.

Stem cell-directed therapies for osteoarthritis: The promise and the practice.

Osteoarthritis (OA) is a disease of an entire synovial joint characterized by clinical symptoms and distortion of joint tissues, including cartilage, muscles, ligaments, and bone. Although OA is a disease of all joint tissues, it is a defined accessible compartment and is thus amenable to topical surgical and regenerative therapies, including stem cells. All tissues arise from stem progenitor cells, and the relative capacity of different cellular compartments, and different individuals, to renew tissues into adulthood may be important in the onset of many different degenerative diseases. OA is driven by both mechanical and inflammatory factors, but how these factors affect the proliferation and differentiation of cells into cartilage in vivo is largely unknown. Indeed, our very basic understanding of the physiological cellular kinetics and biology of the stem-progenitor cell unit of the articular cartilage, and how this is influenced by mechano-inflammatory injury, is largely unknown. OA seems, rather deceptively, to be the low-hanging fruit for stem cell therapy. Without the basic understanding of the stem cell and progenitor unit that generate and maintain articular cartilage in vivo, we will continue to waste opportunities to both prevent and manage this disease. In this review, we discuss the biology of chondrogenesis, the stem cell populations that support articular cartilage in health and disease, and future opportunities afforded through the translation of basic articular chondrocyte stem cell biology into new clinical therapies.

Scleroderma renal crisis: observations from the South Australian Scleroderma Register.

BACKGROUND: Scleroderma renal crisis (SRC) is a rare but feared complication with high morbidity and mortality. Its aetiopathogenesis is unclear. AIM: To investigate epidemiological, serologic and clinical features of all patients with SRC listed on the population-based South Australian Scleroderma Register and to examine possible factors in aetiopathogenesis. METHOD: A case note review was performed on all SRC patients with relevant data extracted to determine incidence, clinical phenotype, presence of autoantibodies and survival. Possible precipitating and aetiopathogenic factors were also examined. Data from the South Australian Scleroderma Register and Australia Bureau of Statistics was sourced for comparative purposes. RESULTS: Over the 34-year period (1985-2018), 30 patients (21 females, 9 males) presented with SRC giving a South Australian mean annual incidence of 0.58/million/year (95% CI 0.39-0.89). Twenty-eight of these patients had diffuse cutaneous scleroderma and two with limited cutaneous scleroderma. The mean age at first symptom of scleroderma was 51.2 ± 15.9 (mean ± SD) years with SRC occurring 4.6 years later (median = 3.0 years, range 0.1-20 years). Possible precipitating factors for SRC included high dose steroids in five patients. Twelve patients were anti- RNA polymerase3 (RNAPol3) positive and two were anti-topoisomerase 1 (Topo1) positive. Renal outcome was poor with 13 patients requiring renal replacement therapy and two proceeding to renal transplantation. The mean age at death was 61.2 ± 11.6 years with SRC patient survival being significantly shorter than patients with diffuse scleroderma without renal involvement (P = 0.002). There was no significant difference in survival between the 1985-2002 and the 2003-2018 SRC cohorts (P = 0.2). Nailfold capillaroscopy performed in 10 patients revealed extensive microvascular damage with prominent capillary drop out. CONCLUSION: SRC is a rare occurrence with an incidence of 0.58/million/year in South Australia. This frequency has not changed over time. It continues to have a severe adverse outcome with frequent requirement for renal replacement therapy and poor survival. Nailfold capillaroscopy revealed evidence of extensive capillary damage. No improvement in survival was observed over the 34-year study period.

Patient satisfaction and acceptability with telehealth at specialist medical outpatient clinics during the COVID-19 pandemic in Australia.

BACKGROUND: Outpatient clinics were shifted rapidly to telehealth in Australia during the Coronavirus disease 19 (COVID-19) pandemic, drastically altering patient care and experience. AIMS: To investigate patient satisfaction and acceptability of telehealth consultations during the COVID-19 pandemic. METHODS: Prospective observation study conducted in two hospital rheumatology outpatient departments (OPD) undertaking telehealth consultations during COVID-19. A modified version of a validated telehealth evaluation survey was posted to all patients attending the telehealth OPD rheumatology clinics, including balanced 5-point Likert scales and free-text responses. Cluster analysis was applied to the Likert-scale questions, alongside thematic analysis of free-text responses. RESULTS: There were 128 respondents (29% response rate), of which 69.5% were women and the majority (87.5%) was aged 50 years or older. All telehealth consultations were conducted by telephone. Nearly one-fifth of patients indicated consistent dissatisfaction with telehealth across the range of questions. These patients were older, reported lower educational qualifications and lower health literacy scores and lacked access to the Internet. While many patients found this mode of consultation to be convenient, patients expressed concerns regarding absence of physical examination. A recurrent theme was a desire for a mixed-model clinic in the future, with flexibility of having both telehealth and face-to-face consultations. CONCLUSIONS: This study offers unique insights into patients' experiences with telehealth, which until the current global pandemic, has been an uncommon mode of consultation delivery in urban areas. This study suggests when defining the place of telehealth in future healthcare delivery, patient perspective and careful patient selection will be key. Disease progression, language and cognitive ability, health literacy, technology access and patient and clinician preference are important considerations when deciding how effectively to embed and integrate telehealth into consultations.

Non-steroidal anti-inflammatory drug (NSAID) therapy in patients with hypertension, cardiovascular, renal or gastrointestinal comorbidities: joint APAGE/APLAR/APSDE/APSH/APSN/PoA recommendations.

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed medications, but they are associated with a number of serious adverse effects, including hypertension, cardiovascular disease, kidney injury and GI complications. OBJECTIVE: To develop a set of multidisciplinary recommendations for the safe prescription of NSAIDs. METHODS: Randomised control trials and observational studies published before January 2018 were reviewed, with 329 papers included for the synthesis of evidence-based recommendations. RESULTS: Whenever possible, a NSAID should be avoided in patients with treatment-resistant hypertension, high risk of cardiovascular disease and severe chronic kidney disease (CKD). Before treatment with a NSAID is started, blood pressure should be measured, unrecognised CKD should be screened in high risk cases, and unexplained iron-deficiency anaemia should be investigated. For patients with high cardiovascular risk, and if NSAID treatment cannot be avoided, naproxen or celecoxib are preferred. For patients with a moderate risk of peptic ulcer disease, monotherapy with a non-selective NSAID plus a proton pump inhibitor (PPI), or a selective cyclo-oxygenase-2 (COX-2) inhibitor should be used; for those with a high risk of peptic ulcer disease, a selective COX-2 inhibitor plus PPI are needed. For patients with pre-existing hypertension receiving renin-angiotensin system blockers, empirical addition (or increase in the dose) of an antihypertensive agent of a different class should be considered. Blood pressure and renal function should be monitored in most cases. CONCLUSION: NSAIDs are a valuable armamentarium in clinical medicine, but appropriate recognition of high-risk cases, selection of a specific agent, choice of ulcer prophylaxis and monitoring after therapy are necessary to minimise the risk of adverse events.

Mining social media data to investigate patient perceptions regarding DMARD pharmacotherapy for rheumatoid arthritis.

OBJECTIVES: We hypothesise that patients have a positive sentiment regarding biological/targeted synthetic disease modifying anti-rheumatic drugs (b/tsDMARDs) and a negative sentiment towards conventional synthetic agents (csDMARDs). We analysed discussions on social media platforms regarding DMARDs to understand the collective sentiment expressed towards these medications. METHODS: Treato analytics were used to download all available posts on social media about DMARDs in the context of rheumatoid arthritis. Strict filters ensured that user generated content was downloaded. The sentiment (positive or negative) expressed in these posts was analysed for each DMARD using sentiment analysis. We also analysed the reason(s) for this sentiment for each DMARD, looking specifically at efficacy and side effects. RESULTS: Computer algorithms analysed millions of social media posts and included 54 742 posts about DMARDs. We found that both classes had an overall positive sentiment. The ratio of positive to negative posts was higher for b/tsDMARDs (1.210) than for csDMARDs (1.048). Efficacy was the most commonly mentioned reason in posts with a positive sentiment and lack of efficacy was the most commonly mentioned reason for a negative sentiment. These were followed by the presence/absence of side effects in negative or positive posts, respectively. CONCLUSIONS: Public opinion on social media is generally positive about DMARDs. Lack of efficacy followed by side effects were the most common themes in posts with a negative sentiment. There are clear reasons why a DMARD generates a positive or negative sentiment, as the sentiment analysis technology becomes more refined, targeted studies could be done to analyse these reasons and allow clinicians to tailor DMARDs to match patient needs.

Review of gout clinic in a tertiary hospital setting.

Although updated consensus guidelines, and effective therapies, are available for management of gout, suboptimal management remains an issue. Barriers were identified and addressed as part of a dedicated, structured gout clinic. More frequent appointments resulted in a faster rate of serum urate reduction, and the clinic provided the opportunity for the education of both patients and general practitioners in the management of gout.

Early development of the Australia and New Zealand Musculoskeletal Clinical Trials Network.

The Australia and New Zealand Musculoskeletal (ANZMUSC) Clinical Trials Network was formed to build capacity and infrastructure for high-quality musculoskeletal clinical trials in our region. The purpose of this paper is to describe the steps taken in its formation to help others interested in establishing similar networks. In particular, we describe the steps taken to form the collaboration and our progress in achieving our vision and mission. Our aim is to focus on trials of highest importance and quality to provide definitive answers to the most pressing questions in our field.

Patients' experience of shoulder disorders: a systematic review of qualitative studies for the OMERACT Shoulder Core Domain Set.

OBJECTIVES: To describe the experiences (including symptoms and perceived impacts on daily living) of people with a shoulder disorder. METHODS: Systematic review of qualitative studies. We searched for eligible qualitative studies indexed in Ovid MEDLINE, Ovid Embase, CINAHL (EBSCO), SportDiscus (EBSCO) and Ovid PsycINFO up until November 2017. Two authors independently screened studies for inclusion, appraised their methodological quality using the Critical Appraisal Skills Programme checklist, used thematic synthesis methods to generate themes describing the experiences reported by participants and assessed the confidence in the findings using the Grading of Recommendations Assessment, Development and Evaluation Confidence in Evidence from Reviews of Qualitative research (GRADE-CERQual) approach. RESULTS: The inclusion criteria were met by eight studies, which included 133 participants (49 females and 84 males) with either rotator cuff disease, adhesive capsulitis, proximal humeral fracture, shoulder instability or unspecified shoulder pain. We generated seven themes to describe what people in the included studies reported experiencing: pain; physical function/activity limitations; participation restriction; sleep disruption; cognitive dysfunction; emotional distress; and other pathophysiological manifestations (other than pain). There were interactions between the themes, with particular experiences impacting on others (e.g. pain leading to reduced activities and sleep disruption). Following grading of the evidence, we considered it likely that most of the review findings were a reasonable representation of the experiences of people with shoulder disorders. CONCLUSION: Patients with shoulder disorders contend with considerable disruption to their life. The experiences described should be considered by researchers seeking to select the most appropriate outcomes to measure in clinical trials and other research studies in people with shoulder disorders.

Methotrexate for psoriatic arthritis.

BACKGROUND: Psoriatic arthritis is an inflammatory disease associated with joint damage, impaired function, pain, and reduced quality of life. Methotrexate is a disease-modifying anti-rheumatic drug (DMARD) commonly prescribed to alleviate symptoms, attenuate disease activity, and prevent progression of disease. OBJECTIVES: To assess the benefits and harms of methotrexate for psoriatic arthritis in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, the WHO International Clinical Trials Registry Platform, and www.clinicaltrials.gov for relevant records. We searched all databases from inception to 29 January 2018. We handsearched included articles for additional records and contacted study authors for additional unpublished data. We applied no language restrictions. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) and quasi-RCTs that compared methotrexate versus placebo, or versus another DMARD, for adults with psoriatic arthritis. We reported on the following major outcomes: disease response (measured by psoriatic arthritis response criteria (PsARC)), function (measured by the Health Assessment Questionnaire for Rheumatoid Arthritis (HAQ)), health-related quality of life, disease activity (measured by disease activity score (28 joints) with erythrocyte sedimentation rate (DAS28-ESR)), radiographic progression, serious adverse events, and withdrawals due to adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently reviewed search results, assessed risk of bias, extracted trial data, and assessed the quality of evidence using the GRADE approach. We undertook meta-analysis only when this was meaningful. MAIN RESULTS: We included in this review eight RCTs conducted in an outpatient setting, in Italy, the United Kingdom, the United States of America, China, Russia, and Bangladesh. Five studies compared methotrexate versus placebo, and four studies compared methotrexate versus other DMARDs. The average age of participants varied across studies (26 to 52 years), as did the average duration of psoriatic arthritis (one to nine years). Doses of methotrexate varied from 7.5 mg to 25 mg orally per week, but most studies administered approximately 15 mg or less orally per week. Risk of bias was generally unclear or high across most domains for all studies. We considered only one study to have low risk of selection and detection bias. The main study informing results of the primary comparison (methotrexate vs placebo up to six months) was at low risk of bias for all domains except attrition bias and reporting bias.We restricted reporting of results to the comparison of methotrexate versus placebo for up to six months. Low-quality evidence (downgraded due to bias and imprecision) from a single study (221 participants; methotrexate dose 15 mg orally or less per week) informed results for disease response, function, and disease activity. Disease response, measured by the proportion who responded to treatment according to PsARC (response indicates improvement), was 41/109 in the methotrexate group and 24/112 in the placebo group (risk ratio (RR) 1.76, 95% confidence interval (CI) 1.14 to 2.70). This equates to an absolute difference of 16% more responders with methotrexate (4% more to 28% more), and a number needed to treat for an additional beneficial outcome (NNTB) of 6 (95% CI 5 to 25). Mean function, measured by the HAQ (scale 0 to 3; 0 meaning no functional impairment; minimum clinically important difference 0.22), was 1.0 points with placebo and 0.3 points better (95% 0.51 better to 0.09 better) with methotrexate; absolute improvement was 10% (3% better to 17% better), and relative improvement 30% (9% better to 51% better). Mean disease activity as measured by the DAS28-ESR (scale of 0 to 10; lower score means lower disease activity; minimum clinically important difference unknown) was 3.8 points in the methotrexate group and 4.06 points in the placebo group; mean difference was -0.26 points (95% CI -0.65 to 0.13); absolute improvement was 3% (7% better to 1% worse), and relative improvement 6% (16% better to 3% worse).Low-quality evidence (downgraded due to risk of bias and imprecision) from three studies (n = 293) informed our results for serious adverse events and withdrawals due to adverse events. Due to low event rates, we are uncertain if methotrexate results show increased risk of serious adverse events or withdrawals due to adverse events compared to placebo. Results show 1/141 serious adverse events in the methotrexate group and 4/152 in the placebo group: RR 0.26 (95% CI 0.03 to 2.26); absolute difference was 2% fewer events with methotrexate (5% fewer to 1% more). In all, 9/141 withdrawals in the methotrexate group were due to adverse events and 7/152 in the placebo group: RR 1.32 (95% CI 0.51 to 3.42); absolute difference was 1% more withdrawals (4% fewer to 6% more).One study measured health-related quality of life but did not report these results. No study measured radiographic progression. AUTHORS' CONCLUSIONS: Low-quality evidence suggests that low-dose (15 mg or less) oral methotrexate might be slightly more effective than placebo when taken for six months; however we are uncertain if it is more harmful. Effects of methotrexate on health-related quality of life, radiographic progression, enthesitis, dactylitis, and fatigue; its benefits beyond six months; and effects of higher-dose methotrexate have not been measured or reported in a randomised placebo-controlled trial.

In the clinic. Rotator cuff disease.

Shoulder pain is a common musculoskeletal disorder and has a substantial negative effect on quality of life. Its monthly prevalence in the general population is reported to be between 18% and 31%, whereas lifetime prevalence ranges between 6.7% and 66.7%. Shoulder pain is the third most frequent musculoskeletal reason to present to primary care and accounts for up to 10% of all referrals to physical therapists. Although the natural history of shoulder pain varies and is often self-limiting,up to half of persons who present for care, particularly the elderly, might continue to have pain and/or functional disturbance for up to 2 years after presentation.

Update on the diagnosis and management of gout.

Gout is a common clinical problem encountered by both general and specialist clinicians. The key principles in gout management include establishing a definitive diagnosis, the swift treatment of acute attacks, and using urate-lowering therapies appropriately to prevent further attacks and joint damage. The gold standard diagnostic tool for gout remains the identification by polarised light microscopy of monosodium urate crystals in synovial fluid or in a tophus. Emerging diagnostic imaging techniques and novel therapies show promise in the diagnosis and treatment of gout. In most cases, using existing therapies judiciously remains the key determinant of success in managing gout.

The scope, funding and publication of musculoskeletal clinical trials performed in Australia.

Musculoskeletal conditions are the leading contributors to disability burden globally and account for 27.4% of total disability burden in Australia. Timely research that addresses important questions relevant to consumers, clinicians and policymakers is critical for reducing the burden associated with these conditions. Clinical trials are particularly important for providing information about whether interventions are effective and safe. They are also needed to test strategies for reducing the sizeable delays in translating evidence into practice. A review of the current scope of musculoskeletal clinical trials in Australia found that National Health and Medical Research Council funding is disproportionally low compared with the burden of these conditions (averaging 5.8 new trials per year through the project grant scheme over the past 5 years, representing 0.8% of all project grants and funding, and 5% of NHMRC clinical trial funding). In the past 2 years, 128 Australian-initiated trials were registered in a trial registry, while about one in 20 randomised trials published in 37 leading general medical and musculoskeletal-specific journals was initiated in Australia. None were implementation trials. Relative to the burden of musculoskeletal conditions in Australia, investment in clinical trials is not ideal. While Australian musculoskeletal trialists are productive and internationally competitive, we may not be addressing the most critical issues. There is an urgent need for Australian researchers, clinicians, policymakers and consumers to work collaboratively to prioritise the most important questions, secure appropriate research funding, and undertake well designed trials to ensure we deliver best evidence-informed care and optimal outcomes for people with musculoskeletal conditions.

Active foot synovitis in patients with rheumatoid arthritis: applying clinical criteria for disease activity and remission may result in underestimation of foot joint involvement.

OBJECTIVE: To determine whether application of criteria for remission in rheumatoid arthritis (RA) may result in underestimation of foot joint involvement among patients in a clinic setting. METHODS: RA patients (n = 123) were assessed at baseline and 6 months after commencement of a response-driven combination disease-modifying antirheumatic drug (DMARD) protocol. Remission was assessed using disease activity measures (the 28-joint Disease Activity Score using the erythrocyte sedimentation rate [DAS28-ESR], Simplified Disease Activity Index [SDAI], and Clinical Disease Activity Index [CDAI]) as well as Boolean-based criteria for remission (the 1981 American College of Rheumatology [ACR] preliminary criteria and the 2011 ACR/European League Against Rheumatism [EULAR] provisional criteria). The prevalence of foot synovitis and the mean swollen/tender foot joint count in RA patients meeting any of these remission criteria were estimated by hurdle (mixed distribution) regression. RESULTS: In patients who received 6 months of combination DMARD treatment, application of the 1981 ACR criteria and the newly proposed 2011 ACR/EULAR criteria, each utilizing full joint counts (which includes assessment of the feet), classified the least number of patients as being in remission (8-10%), and evidence of foot synovitis was minimal among these patients. In contrast, ongoing foot synovitis was present in a substantial proportion of patients (>20%) meeting the 28-joint count criteria for remission, including the DAS28-ESR, SDAI, CDAI, and 2011 ACR/EULAR criteria (clinical practice setting or clinical trials). Furthermore, applying the 2011 ACR/EULAR composite remission criterion of a SDAI score ≤3.3 to define remission did not adequately capture the resolution of foot synovitis (i.e., residual foot involvement was still detected in a substantial proportion of patients classified as being in remission by this definition). CONCLUSION: Although the DAS28-ESR, CDAI, and SDAI have been validated for assessment of remission in RA, this study shows that the performance of these 3 disease activity measures, which do not provide a direct assessment of the foot, in detecting foot synovitis is poor, in contrast to that of the 1981 ACR and 2011 ACR/EULAR remission criteria utilizing full joint counts. Thus, patients may be at risk of ongoing damage if treatment decisions are made solely on the basis of criteria that omit foot joint assessment.
