Meta AnalysisAn updated meta-analysis of the signal transducer and activator of transcription 4 (STAT4) rs7574865 G/T polymorphism and rheumatoid arthritis risk in an Asian population.
Signal transducer and activator of transcription 4 (STAT4) transmits signals induced by the cytokines interleukin (IL)-12, IL-23, and interferon (IFN)-γ, which play an important role in the development of rheumatoid arthritis (RA). Studies have shown conflicting results concerning the association between the rs7574865 G/T polymorphism in the STAT4 gene and RA in an Asian population. We have performed a meta-analysis to examine this relationship. ⋯ Our study indicates that the STAT4 rs7574865 G/T polymorphism was significantly associated with a decreased RA risk in an Asian population.

Left heart disease: a frequent cause of early pulmonary hypertension in systemic sclerosis, unrelated to elevated NT-proBNP levels or overt cardiac fibrosis but associated with increased levels of MR-proANP and MR-proADM: retrospective analysis of a French Canadian cohort.
Pulmonary hypertension (PH) causes mortality in systemic sclerosis (SSc). Pulmonary arterial hypertension (PAH) and left heart disease (LHD) are frequent causes of PH. Therefore, we studied PAH and LHD in early PH. ⋯ Early PH in SSc, like late PH, is heterogeneous and RHC is essential for determining its underlying cause. The most frequent cause of early PH was LHD. Levels of MR-proANP and MR-proADM, but not NT-proBNP, were increased in early LHD-PH, and may be more reliable than NT-proBNP as a biomarker of early PH in this subgroup of patients. Cardiac MRI did not explain LHD-PH. This study is the first to identify a high frequency of LHD in early PH correlating with normal NT-proBNP levels but increased MR-proANP and MR-proADM levels in SSc patients.

Observational StudyManagement of temporomandibular joint arthritis-related orofacial symptoms in juvenile idiopathic arthritis by the use of a stabilization splint.
Temporomandibular joint (TMJ) inflammation in patients with juvenile idiopathic arthritis (JIA) may interfere with optimal joint and muscle function. Orofacial symptoms are common findings in relation to TMJ arthritis. Previous research on management of TMJ arthritis-related orofacial symptoms in patients with JIA has focused on pharmacological treatment modalities without involving physical pain management strategies. The aim of this study was to evaluate changes in orofacial pain and TMJ function after stabilization splint treatment. ⋯ The stabilization splint is a safe, reversible, low-cost treatment, and familiar to most dental practitioners. Based on our findings, we propose the implementation of stabilization splint therapy for the treatment of JIA patients with TMJ arthritis-related symptoms.

Comparative StudyPain in primary Sjögren's syndrome: the role of catastrophizing and negative illness perceptions.
Pain is a major factor in health quality in Sjögren's syndrome (SS), but little is known about the factors that contribute to pain severity. Because pain perception has been linked to catastrophizing in other diseases, we assessed subjects with primary SS (pSS) to explore a possible link between pain, illness appraisal, and catastrophizing. ⋯ Pain catastrophizing was a significant predictor of pain severity in both seropositive and seronegative pSS patients. This study suggests that behavioural interventions designed to reduce pain catastrophizing and negative appraisal of illness could be of benefit in pSS patients. Research is needed to test the effect of psycho-educational therapies on key patient-reported outcomes, particularly pain, depression, and fatigue, in pSS.
