Objectives: To assess the comparative safety of tumor necrosis factor inhibitor (TNFi), non-TNFi, and Janus kinase inhibitor (JAKi) biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARD) in patients with rheumatoid arthritis (RA) for the risk of major adverse cardiovascular events (MACE) using US administrative claims data.

Methods: We performed a cohort study using MerativeTM Marketscan® Research Databases (2012-2021) of individuals aged 18-64 years with RA initiating b/tsDMARD treatment. We used Cox proportional hazard models to estimate hazard ratios (HR) and 95% CI for developing MACE within 2 years of b/tsDMARD initiation, adjusting for potential confounders.

Objective: Radiographic axial spondyloarthritis (r-axSpA) has a 7-year average diagnostic delay. Although the effects of sex or gender on time to diagnosis have been evaluated, the role of social determinants of health remains understudied. We assessed whether time from initial clinical documentation of r-axSpA symptoms to r-axSpA diagnosis (diagnostic delay) varies based on sex, race, ethnicity, and/or the presence of social needs.

Article Synopsis
  • A multicentre, retrospective study analyzed the retention rates and reasons for stopping treatment in elderly patients with rheumatoid arthritis (EORA), comparing Janus kinase inhibitors (JAKi) to biologic disease-modifying drugs.
  • The study found that IL-6 inhibitors had better retention rates than TNF inhibitors, while JAKi showed lower discontinuation due to ineffectiveness but higher rates of discontinuation due to adverse events compared to TNF inhibitors.
  • The conclusions suggest that while IL-6i and JAKi are effective for EORA patients, the increased risk associated with JAKi requires careful consideration and a tailored treatment approach.

Background: The use of social media in health care may serve as a beneficial tool for education, information dissemination, telemedicine, research, networking, and communications. To better leverage the benefits of social media, it is imperative to understand the patterns of its use and potential barriers to its implementation in health care. A previous study in 2016 that investigated social media use among young clinical rheumatologists (≤45 years) and basic scientists showed that there was substantial social media use among them for social and professional reasons.

Null-polarimeters provide the best sensitivity to anisotropy measurements and so far have been developed for the detection of small optical activities. This paper revisits null polarimetry through an original configuration based on the concept of spectrally encoded light polarization, in order to measure, with unprecedented speed, either linear or circular retardance with the same degree of sensitivity . Using passive polarization optics and a high speed wavelength swept laser source, the achieved single-pass sensitivity was 55nrad/Hz and 45nrad/Hz for respectively linear and circular retardance considering a minimum acquisition time of 10 µs.
