Abstract: To develop and test the interreader reliability of the OMERACT Hand Osteoarthritis Magnetic Resonance Scoring System (HOAMRIS) for assessment of structural and inflammatory hand OA features in the interphalangeal joints. The HOAMRIS was developed through an iterative process. Selection of features and their scaling was agreed upon through consensus by members of the OMERACT Magnetic Resonance Imaging (MRI) Task Force, using the Oslo Hand Osteoarthritis (OA) MRI Score system as a template. Two reliability exercises were performed, in which 6 and 4 readers participated, respectively. After the first exercise, an atlas was developed and used in the second exercise to facilitate reading. In each exercise, readers independently scored 8 MRI scans from the Oslo Hand OA cohort (coronal/axial short-tau inversion recovery and coronal/axial/sagittal T1-weighted fat-suppressed pre- ost-Gadolinium images). Interreader reliability was assessed by intraclass correlation coefficients (ICC), percentage exact and close agreement (PEA/PCA). The preliminary OMERACT HOAMRIS included assessment of synovitis, erosive damage, cysts, osteophytes, cartilage space loss, malalignment, and bone marrow lesions (BML), of which all were scored on a 0–3 scale for normal, mild, moderate, and severe (increments of 0.5 for synovitis, erosive damage, and BML). In the first exercise, most features showed good to very good ICC values (0.64–0.94), except synovitis (0.34). In the second exercise using the atlas, the ICC values were 0.74 for all MRI features, and the PEA/PCA values were higher than in the first exercise. A preliminary HOAMRIS with good to very good interreader reliability was developed. Longitudinal studies are needed to assess its sensitivity to change.

Abstract: To assess the predictive value of magnetic resonance imaging (MRI)-detected subclinical inflammation for subsequent radiographic progression in a longitudinal study of patients with rheumatoid arthritis (RA) in clinical remission or low disease activity (LDA), and to determine cutoffs for an MRI inflammatory activity acceptable state in RA in which radiographic progression rarely occurs. Patients with RA in clinical remission [28-joint Disease Activity Score-C-reactive protein (DAS28-CRP) 2.6, n = 185] or LDA state (2.6 ≤ DAS28-CRP 3.2, n = 69) with longitudinal MRI and radiographic data were included from 5 cohorts (4 international centers). MRI were assessed according to the Outcome Measures in Rheumatology (OMERACT) RA MRI scoring system (RAMRIS). Statistical analyses included an underlying conditional logistic regression model stratified per cohort, with radiographic progression as dependent variable. A total of 254 patients were included in the multivariate analyses. At baseline, synovitis was observed in 95% and osteitis in 49% of patients. Radiographic progression was observed in 60 patients (24%). RAMRIS synovitis was the only independent predictive factor in multivariate analysis. ROC analysis identified a cutoff value for baseline RAMRIS synovitis score of 5 (maximum possible score 21). Rheumatoid factor (RF) status yielded a significant interaction with synovitis (p value = 0.044). RF-positive patients with a RAMRIS synovitis score of 5 vs ≤ 5, had an OR of 4.4 (95% CI 1.72–11.4) for radiographic progression. High MRI synovitis score predicts radiographic progression in patients in clinical remission/LDA. A cutoff point for determining an MRI inflammatory activity acceptable state based on the RAMRIS synovitis score was established. Incorporating MRI in future remission criteria should be considered.

Abstract: Australia needs a new shared vision that the current trajectory of loss of natural heritage on its offshore islands is not acceptable and needs to change. This Special Issue brings together seven papers from leaders and practitioners with experience in offshore islands across the Australian and New Zealand context. The fundamentals for each paper are to suggest potential solutions or scenarios to move forward with island policy, and management.

Abstract: If conservation depends on people, then community partnerships are the lynchpin to conservation success. The contribution of local knowledge, intellectual capital and volunteer labour not only saves project managers invaluable time and money, it fosters ownership and longevity into conservation initiatives well beyond their projected timeframe. Island communities are socially and culturally erse and driven by a range of motivations. Hence, if we are to deliver conservation programs at scale, we need to better understand and embed these drivers into program design. We present four contemporary case studies on major populated islands in Australia where community collaborations are building the collective impact needed to underpin conservation success. They contain key learnings about community involvement, to help guide managers with future island planning and avoid some pitfalls.

Abstract: Australia’s approach to managing and conserving its offshore islands as important national assets warrants urgent review. There is a growing realisation that the current trajectory of loss of natural heritage on islands must be reversed, particularly in an era of increasing climate change. We propose a role description and an organisational model for a national Australian Islands Alliance that ch ions conservation action, prioritises investments aligned to risks, and that connects partners at a strategic national level. A national alliance offers important opportunity to assess threats and report on condition. Four key foundations underpin a national alliance dedicated to ch ioning island care and expert management: (1) management informed by evidence (2) sound return on investment (3) national coordination in partnership with States and Territories and (4) community participation inclusive of Aboriginal peoples’ and Torres Strait Islanders’ custodial rights and interests. The message from experiences shared across Australia, New Zealand and the Pacific region is that traditional island custodians and stakeholders are vital partners to restoration efforts. These shared learnings collectively demonstrate the time is now for Australia to move forward with a respectful and unified direction to progress successful and sustainable island conservation and restoration.
