We investigated the electrophysiological properties of the heart in patients with definite or classical rheumatoid arthritis using programmed electrical stimulation techniques. Twelve patients with rheumatoid arthritis and without evidence of organic heart disease or arrhythmia detectable with serial electrocardiograms and 24-hour ambulatory electrocardiographic monitoring were compared with 12 control subjects. Stimulation was performed from the high right atrium and right ventricular apex at a drive cycle length of 600 msec and the recording sites included high right atrium, atrioventricular junction and distal coronary sinus. There was no statistically significant difference in the corrected sinus node recovery time between the study and control group of patients. Similarly, no differences from normal were found in the AH and HV intervals or in the atrial and ventricular refractoriness, whereas the atrioventricular nodal effective refractory period was higher in patients with rheumatoid arthritis, compared with the control group (338 +/- 38 vs 286 +/- 29, P less than 0.02). The atrial conduction time during basic cycle length had a tendency to increase from high right atrium to atrioventricular junction in the study group and reached statistical significance from high right atrium to coronary sinus (92 +/- 15 vs 74 +/- 14, P less than 0.05). Electrophysiologic differences between the study and control patients also included a greater increase in maximal intraatrial (40 +/- 13 vs 27 +/- 16, P less than 0.05) and interatrial conduction delay (54 +/- 16 vs 31 +/- 12, P less than 0.01) of early premature stimuli in patients with rheumatoid arthritis.(ABSTRACT TRUNCATED AT 250 WORDS)

Rheumatoid arthritis (RA) is a systemic, progressive illness marked by persistent synovitis that causes substantial functional disability. Treatment delays frequently affect health-related quality of life. Extra-articular features are prevalent findings in RA, which leads to significant morbidity and mortality.

Objectives: To determine the features of rheumatoid pulmonary nodules and the factors associated with nodule progression in patients with rheumatoid arthritis.
Methods: Between January 2010 and September 2018, RA patients with at least one chest computed tomography (CT) were included. Two experienced radiologists examined chest CTs.

Objectives: This study was aimed to investigate the efficacy of comprehensive conservative treatments in patients with temporomandibular joint (TMJ) retrodiscal layer rupture and/or disc perforation.
Materials And Methods: This was a retrospective study of thirty-one consecutive patients with findings of TMJ retrodiscal layer rupture and/or disc perforation using magnetic resonance imaging. Comprehensive stomatognathic system assessments were performed.

Objective: Interstitial lung disease (ILD) is rare, but it is one of the most frequent extra-articular manifestations and a relevant cause of morbidity and mortality in rheumatoid arthritis (RA). Over the past few years, Janus kinase inhibitors (JAKis) have been reported to have promising efficacy in the treatment of active RA, but recent concerns have been raised about their safety profile, namely malignancy and cardiovascular disease, limiting their use to certain patient categories.
Methods: The objective of this narrative review is to summarize the current evidence of the efficacy and safety of JAKis in RA-ILD management, investigating a possible emerging role for this drug class in such subset of patients.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disorder that causes joint inflammation and affects quality of life. Appropriate physical activity can enhance joint function and lower cardiovascular disease risk. However, individuals with RA often have reduced physical activity levels, likely due to kinesiophobia, or fear of movement.
