Effectiveness of methotrexate and bridging glucocorticoids with or without early introduction of a 6-month course of etanercept in early RA: results of the 2-year, pragmatic, randomised CareRA2020 trial.

Objectives: To investigate if patients with early rheumatoid arthritis responding insufficiently to initial methotrexate (MTX) and bridging glucocorticoids (GCs) could benefit from early but temporary etanercept introduction as a second remission-induction attempt.

Methods: CareRA2020 (NCT03649061) was a 2-year, open-label, multicentre, pragmatic randomised controlled trial. Treatment-naïve patients started MTX and GC bridging (COBRA-Slim: CS).

No effects of cervical spine motion on cranial dura mater strain.

Objective: The aim of this study was to analyze the effects of cervical spine motion on cranial dura mater length variations in anatomical specimens using high-resolution linear displacement transducers. We hypothesized that transducer resolution was sufficient to measure dura mater length changes if they occurred during cervical spine motion.

Design: Cranial dura mater strain was measured using differential variable reluctance transducers during cervical spine motion in 11 formaldehyde-fixed whole-body anatomical specimens (mean age: 82 years).
