Association of systemic lupus erythematosus with a higher risk of cervical but not trochanteric hip fracture: a nationwide population-based study.
To determine the incidence rates and risk factors of cervical and trochanteric hip fractures (HFs) among patients with systemic lupus erythematosus (SLE) based on a nationwide population-based data set. ⋯ SLE is associated with a higher risk for cervical but not trochanteric HF, and these 2 types of HFs have different risk factors.

ReviewSystematic review and critical appraisal of validation studies to identify rheumatic diseases in health administrative databases.
To evaluate the quality of the methods and reporting of published studies that validate administrative database algorithms for rheumatic disease case ascertainment. ⋯ The methods used in administrative data validation studies of rheumatic diseases are highly variable. Few studies reported key measures of diagnostic accuracy despite their importance for drawing conclusions about the validity of administrative database algorithms. We developed a methodologic framework and recommendations for validation study conduct and reporting.

Review Meta AnalysisUtility of anti-melanoma differentiation-associated gene 5 antibody measurement in identifying patients with dermatomyositis and a high risk for developing rapidly progressive interstitial lung disease: a review of the literature and a meta-analysis.
To assess the utility of anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody measurement for predicting a risk for developing rapidly progressive interstitial lung disease (RP-ILD) in patients with polymyositis/dermatomyositis (PM/DM). ⋯ Detection of anti-MDA5 antibody is a valuable tool for identifying DM patients with a high risk for developing RP-ILD, but the distribution of classic DM and CADM in patients with this antibody varies among ethnic groups.

Multicenter Study Comparative StudyEuropean League Against Rheumatism Sjögren's Syndrome Disease Activity Index and European League Against Rheumatism Sjögren's Syndrome Patient-Reported Index: a complete picture of primary Sjögren's syndrome patients.
The European League Against Rheumatism (EULAR) Sjögren's Syndrome (SS) Disease Activity Index (ESSDAI) and the EULAR SS Patient-Reported Index (ESSPRI) were recently developed. We aimed to determine whether patients' symptoms differed between patients with and without systemic involvement and if the disease-specific indices correlated with each other in primary SS. ⋯ Alterations of common patient-reported outcomes are present in all patients with primary SS, including those with systemic complications. However, patient symptoms and systemic complications are 2 different facets of primary SS. Therefore, the use of both systemic and patients' indices, such as the ESSDAI and ESSPRI, are useful. Since these 2 facets weakly overlap, one should identify which of both components is the main target of the treatment to test, when designing clinical trials in primary SS.

Randomized Controlled TrialEffect of moderate to vigorous physical activity on long-term clinical outcomes and pain severity in fibromyalgia.
To evaluate the relationship between long-term maintenance of moderate to vigorous physical activity (MVPA) and clinical outcomes in fibromyalgia (FM). ⋯ Increased participation in MVPA for at least 12 weeks improved physical function and overall well-being in patients with FM. Although sustained physical activity was not associated with greater clinical benefit compared with unsustained physical activity, these findings also suggest that performing greater volumes of physical activity is not associated with worsening pain in FM. Future research is needed to determine the relationship between sustained MVPA participation and subsequent improvement in patient outcomes.
