BACKGROUND: To understand the relationship between regulatory B cells (Bregs) and juvenile idiopathic arthritis (JIA), we analyzed the percentages of Bregs and their function in peripheral blood (PB) and synovial fluid (SF) of JIA patients.

METHODS: Twenty-one JIA patients and 11 children with growing pain but without known rheumatic diseases as controls were included. The B cell phenotype and intracellular production of IL-10 of Bregs were assessed by flow cytometry. Mononuclear cells from PB and SF were stimulated to produce IL-10 in vitro for the identification of IL-10- producing regulatory B cells.

RESULTS: The percentage of CD24

CONCLUSIONS: The inability …

Pediatric Rheumatology: Addressing The Transition To Adult-Orientated Health Care., Sara Sabbagh, Tova Ronis, Patience H White

Medicine Faculty Publications

The transition from pediatric to adult health care is often a challenging process due to multiple interwoven complexities, especially for children with chronic medical conditions. Health care transition (HCT) is a process of moving from a pediatric to an adult model of health care with or without a transfer to a new clinician. This paper focuses on what is known about HCT for youth and young adults (Y/YA) with rheumatic diseases within a larger context of HCT recommendations. HCT barriers for youth, families, and providers and current evidence for a structured HCT processes are reviewed. Practical advice is offered on …

Evaluation Of Performance, Acceptance, And Compliance Of An Auto-Injector In Healthy And Rheumatoid Arthritic Subjects Measured By A Motion Capture System., Xiao Xiao, Wei Li, Corbin Clawson, David Karvani, Perceval Sondag, James K Hahn

Pediatrics Faculty Publications

Purpose: The study aimed to develop a motion capture system that can track, visualize, and analyze the entire performance of self-injection with the auto-injector.

Methods: Each of nine healthy subjects and 29 rheumatoid arthritic (RA) patients with different degrees of hand disability performed two simulated injections into an injection pad while six degrees of freedom (DOF) motions of the auto-injector and the injection pad were captured. We quantitatively measured the performance of the injection by calculating needle displacement from the motion trajectories. The max, mean, and SD of needle displacement were analyzed. Assessments of device acceptance and usability were evaluated …
