Changes in ultrasound imaging of joints, entheses, bursae and tendons 24 and 48 h after adjusted weight training.

Background: Joint effusion and enthesitis are common ultrasound findings in rheumatic diseases such as rheumatoid arthritis or spondyloarthritis. However, changes of joints and entheses were not only observed in patients but also in physically active individuals and athletes.

Objectives: The purpose of this study was to evaluate joint, entheseal, bursal and tendon musculoskeletal ultrasound (MSUS) findings in large and medium joints of young healthy individuals after completing a standardised weight training.

Humoral immunogenicity of COVID-19 vaccines in patients with inflammatory rheumatic diseases under treatment with Rituximab: a case-control study (COVID-19VacRTX).

Objectives: Patients with inflammatory rheumatic diseases (IRDs) treated with the anti-CD20 mAb rituximab (RTX) have been identified as high-risk for severe COVID-19 outcomes. Additionally, there is increased risk due to reduced humoral immune response, induced by therapeutic B cell depletion. This study sought to quantify humoral response after vaccination against SARS-CoV-2 in patients with IRD treated with RTX.

Prevalence of joint, entheseal, tendon, and bursal findings in young, healthy individuals by musculoskeletal ultrasound.

Objective: The purpose of this study was to determine the prevalence of joint, enthesis, bursa, and tendon ultrasound findings in large and medium joints of young, healthy individuals.

Method: Ultrasound assessment of large and medium joints, bursae, tendons, and entheses was performed in healthy individuals below the age of 30 years. Participants also underwent bioelectrical impedance analysis and conducted supervised weight training to determine maximum strength.
