The relationship between disease activity and quality of life in rheumatoid arthritis patients: a network analysis.

Background: The relationship between disease activity and quality of life (QoL) in rheumatoid arthritis (RA) patients was explored using network analysis. The focus of network analysis has recently shifted from studying individual groups to comparing the network structures of different subgroups. RA patients with depressive symptoms generally have lower QoL scores, so we compared the QoL networks of RA patients with and without depressive symptoms to test for differences.

The predictive value of Holter monitoring in the risk of obstructive sleep apnea.

Background: Patients with obstructive sleep apnea (OSA) often present with cardiovascular symptoms. Holter monitors were reported to predict sleep apnea, though were rarely used in everyday clinical practice. In this study, by comparing Holter monitoring to polysomnography (PSG), we try to find out an operable way for clinicians to use Holter to predict OSA risk.
