Association Between Metabolic Syndrome and Radiographic Changes in Psoriatic Arthritis: A Cohort Study

Arthritis Care &Research, EarlyView.
Objective Metabolic syndrome (MetS) is a known comorbidity of psoriatic arthritis (PsA) and is associated with PsA disease activity. We aimed to explore the association between MetS and radiographic features (peripheral and axial) in PsA. Methods We included patients with PsA followed at our prospective observational cohort for the period between 1978 ...

Stochastic Geometry and Dynamical System Analysis of Walker Constellation Networks [PDF]

arXiv
In practice, low Earth orbit (LEO) and medium Earth orbit (MEO) satellite networks consist of multiple orbits, each populated with many satellites. A widely used spatial architecture for satellites is the Walker constellation, where the longitudes of orbits are equally spaced and the satellites are periodically distributed along the orbits.

The Longitudinal Relationship Between Pain and Depression in People with Inflammatory Arthritis: a Narrative Review

Arthritis Care &Research, Accepted Article.
As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Co‐morbid depression is prevalent in adults with IA, affecting 15 to 39% of people. Whilst pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.
