A multivariable prediction model to identify anti-CCP positive people in those with non-specific musculoskeletal symptoms in primary care.

Objectives: We aimed to develop a prediction model identifying people presenting to primary care with musculoskeletal symptoms likely to be anti-CCP positive and therefore at risk of developing rheumatoid arthritis (RA).

Methods: Participants aged ≥16 years, with new-onset non-specific musculoskeletal symptoms and no history of clinical synovitis, completed a symptom questionnaire and had an anti-CCP test. Model development used LASSO-penalised logistic regression, performance was assessed using area under the receiver operating characteristic curve (AUROC) and decision curve analysis, model over-fit was estimated using bootstrapping and cross-validation.

The usefulness of ultrasound in predicting outcomes in patients with shoulder pain: a prospective observational study.

Objectives: Shoulder pain is common but current clinical classification has limited utility. We aimed to determine whether groups of ultrasound-based shoulder pathologies exist and to evaluate outcomes according to identified groups and individual pathologies.

Methods: This was a prospective study of a community-based cohort with shoulder pain referred for their first ultrasound scan at a single radiology unit, with subsequent routine clinical care.

Predicting Inflammatory Arthritis in At-Risk Persons: Development of Scores for Risk Stratification.

Background: Inflammatory arthritis (IA) is an immune-related condition defined by the presence of clinical synovitis. Its most common form is rheumatoid arthritis.

Objective: To develop scores for predicting IA in at-risk persons using multidimensional biomarkers.

Evaluation of two electronic-rehabilitation programmes for persistent knee pain: protocol for a randomised feasibility trial.

Introduction: Persistent, knee pain is a common cause of disability. Education and exercise treatment are advocated in all clinical guidelines; however, the increasing prevalence of persistent knee pain presents challenges for health services regarding appropriate and scalable delivery of these treatments. Digital technologies may help address this, and this trial will evaluate the feasibility and acceptability of two electronic-rehabilitation interventions: 'My Knee UK' and 'Group E-Rehab'.
