The Role of β-catenin in Synovial Lining Fibroblast Differentiation
Background/Purpose: In healthy synovium, lining fibroblasts promote joint health by secreting proteoglycans that lubricate the joint cavity. In rheumatoid arthritis (RA), sublining fibroblasts undergo marked…Abstract Number: 0610 • ACR Convergence 2022
Patient-derived Organoids Reveal Transcriptional Regulation of Synovial Lining Fibroblast Differentiation
Background/Purpose: Synovial lining fibroblasts secrete factors into the joint cavity that promote joint lubrication1. In inflammatory arthritis, sublining fibroblasts undergo marked expansion while lining fibroblasts…Abstract Number: 0803 • ACR Convergence 2022
Performance of Adenosine Deaminase Activity in Sinovial Fluid for the Early Diagnosis of Tuberculous Arthritis: A Meta Analysis
Background/Purpose: Adenosine deaminase (ADA) activity has shown good performance in diagnosing pleural, peritoneal, and meningeal tuberculosis. This study aimed to evaluate the performance of measuring…Abstract Number: 0972 • ACR Convergence 2022
Automated Joint Space Width Measurement for Hand Osteoarthritis: A Deep Learning Approach
Background/Purpose: Hand osteoarthritis (OA) can be assessed visually through radiographs using Kellgren and Lawrence (KL) system. However, the KL grading system is not fully objective…Abstract Number: 1511 • ACR Convergence 2022
Is There a Correlation Between Skin and Musculoskeletal Activity in Psoriatic Arthritis
Background/Purpose: The majority of patients with PsA present with skin manifestations first. Several studies have examined the relationship between activity/severity of skin and joint manifestations,…Abstract Number: 1914 • ACR Convergence 2022
Acoustic Classification of Early and Advanced Osteoarthritis of the Knee in Clinical Settings
Background/Purpose: Knee osteoarthritis (OA) is a prevalent and debilitating disease. Diagnosis of early knee OA is difficult and insensitive with current technologies. The human knee…Abstract Number: 2205 • ACR Convergence 2022
Non-Invasive in Vivo Metabolic Profiling of Inflammation in Joints and Entheses by Optoacoustic Imaging
