- Diverging perceptions between individual patients with somatic diseases and their healthcare professionals might cause problems in communication and decision-making. To date, no measurement tool is available to compare the illness perceptions between these two groups. The Revised Illness Perception Questionnaire (IPQ-R) is a validated, widely used instrument in many patient populations with somatic conditions. The aim of this study was to adapt the IPQ-R to a healthcare professional's version (IPQ-R HP) and to perform a preliminary evaluation of its validity and reliability.

- Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) are complex chronic auto-immune diseases characterized by multiple organ involvement, comorbidities, and complications. This complexity results in a need for a multidisciplinary management and treatment of SLE and SSc by physicians from a number of medical disciplines, all of who may have different perceptions concerning the condition of a particular patient. The aim of this study was to explore differences in physicians' perceptions on the illness of SLE and SSc patients. Physicians from nine disciplines working at three hospitals in Belgium completed illness perception questionnaires for healthcare professionals based on four patient vignettes, i.e., two vignettes per disease (SLE-SSc). Statistical analysis was carried out by a k-means clustering technique for clustering physicians according to their illness perceptions. Fifty physicians, 62% men with a mean age of 42.8 years (SD 11.3) and mean working experience of 12.7 years (SD 11.6), participated. For each disease, three clusters of physicians with different scores in illness perceptions were identified. For SLE, these clusters were specified as the 'optimistic' group, the 'realistic' group, and the 'overwhelming impact by disease' group. For SSc, the clusters were characterized as the 'optimistic' group, the 'realistic' group, and the 'skeptical' group. We found divergent illness perceptions across physicians of the same and other disciplines. Our study yielded three clusters of physicians per disease with a large variability in illness perceptions. Further studies should focus on the factors that determine these differences and their consequences for patient care.

- Discrepancies in illness representations between patients and physicians result in treatment difficulties, decreased well-being of patients and misunderstandings and disrupted communication. Hence, the objective of this study was to compare illness perceptions of individual patients with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), their rheumatologists and their general practitioners (GPs) and explore potential differences.This study has a cross-sectional design. Patients with SLE and SSc, who were followed at the rheumatology department of the University Hospitals Leuven (Belgium), completed the revised Illness Perception Questionnaire which measures patients' perceptions of their condition and captures nine dimensions. Physicians completed the Revised Illness Perception Questionnaire for Healthcare Professionals which consists of seven dimensions and measures perceptions of the healthcare professional regarding the disease of their patients. Intraclass correlation was performed to examine relationships between pairs of respondents; Cohen's d was used for estimating the magnitude of the difference.Questionnaires were sent to 284 patients of whom 241 (113 SSc and 128 SLE patients) were included. Five rheumatologists and 160 GPs participated. For both diseases, positive correlations were found for 'consequences', 'illness coherence' and 'emotional representations' among patients, rheumatologists and GPs. GPs scored higher on the 'consequences' of these diseases for the patient (d=0.71 for SLE; d=0.80 for SSc). Differences between rheumatologists and GPs were small for SSc and moderate to large for 'consequences' (d=0.56) and 'timeline acute/chronic' (d=0.95) in SLE with higher scores for GPs.For both diseases and among the three groups, significant correlations are detected for the dimensions 'consequences', 'illness coherence' and 'emotional representations'. Differences between rheumatologists and GPs were mainly detected in the case of SLE patients. This can have implications for the collaboration between these two groups of physicians in daily clinical practice.NCT02655640; Pre-results.

- When individuals become ill, they want to understand and give meaning to their illness. The interpretation of this illness experience, or illness perception, is influenced by a range of individual, contextual, and cultural factors. Some of these factors may be modifiable by nursing interventions. The purpose of this systematic review was to investigate which modifiable factors were correlated with illness perceptions across studies of adults with different chronic somatic diseases. Using search terms tailored to each of four electronic databases, studies retrieved were reviewed by two independent evaluators, and each relevant article was assessed for methodological quality. Results were standardized by calculating correlation coefficients. Fifteen papers on illness perceptions in a variety of chronic diseases met the inclusion criteria. All used standardized measures of illness perceptions. We identified five groups of modifiable correlates of illness perceptions: illness-related factors, psychosocial factors, medication beliefs, information provision and satisfaction with information received, and quality of care. Our findings add to the knowledge of modifiable factors correlated with illness perceptions, including the importance of illness-related factors and psychosocial factors such as anxiety and depression. Knowledge of these correlates can facilitate understanding of patients' illness perceptions and might be useful in tailoring patient education programs.

- BACKGROUND: Clinical studies with work participation (WP) as an outcome domain pose particular methodological challenges that hamper interpretation, comparison between studies and meta-analyses.OBJECTIVES: To develop Points to Consider (PtC) for design, analysis and reporting of studies of patients with inflammatory arthritis that include WP as a primary or secondary outcome domain.METHODS: The EULAR Standardised Operating Procedures were followed. A multidisciplinary taskforce with 22 experts including patients with rheumatic diseases, from 10 EULAR countries and Canada, identified methodologic areas of concern. Two systematic literature reviews (SLR) appraised the methodology across these areas. In parallel, two surveys among professional societies and experts outside the taskforce sought for additional methodological areas or existing conducting/reporting recommendations. The taskforce formulated the PtC after presentation of the SLRs and survey results, and discussion. Consensus was obtained through informal voting, with levels of agreement obtained anonymously.RESULTS: Two overarching principles and nine PtC were formulated. The taskforce recommends to align the work-related study objective to the design, duration, and outcome domains/measurement instruments of the study (PtC: 1-3); to identify contextual factors upfront and account for them in analyses (PtC: 4); to account for interdependence of different work outcome domains and for changes in work status over time (PtC: 5-7); to present results as means as well as proportions of patients reaching predefined meaningful categories (PtC: 8) and to explicitly report volumes of productivity loss when costs are an outcome (PtC:9).CONCLUSION: Adherence to these EULAR PtC will improve the methodological quality of studies evaluating WP.

- Objectives The aim of this study was to confirm the influence of TNFSF4 polymorphisms on systemic sclerosis (SSc) susceptibility and phenotypic features. Methods A total of 8 European populations of Caucasian ancestry were included, comprising 3014 patients with SSc and 3125 healthy controls. Four genetic variants of TNFSF4 gene promoter (rs1234314, rs844644, rs844648 and rs12039904) were selected as genetic markers. Results A pooled analysis revealed the association of rs1234314 and rs12039904 polymorphisms with SSc (OR 1.15, 95% CI 1.02 to 1.31; OR 1.18, 95% CI 1.08 to 1.29, respectively). Significant association of the four tested variants with patients with limited cutaneous SSc (lcSSc) was revealed (rs1234314 OR 1.22, 95% CI 1.07 to 1.38; rs844644 OR 0.91, 95% CI 0.83 to 0.99; rs844648 OR 1.10, 95% CI 1.01 to 1.20 and rs12039904 OR 1.20, 95% CI 1.09 to 1.33). Association of rs1234314, rs844648 and rs12039904 minor alleles with patients positive for anti-centromere antibodies (ACA) remained significant (OR 1.23, 95% CI 1.10 to 1.37; OR 1.12, 95% CI 1.01 to 1.25; OR 1.22, 95% CI 1.07 to 1.38, respectively). Haplotype analysis confirmed a protective haplotype associated with SSc, lcSSc and ACA positive subgroups (OR 0.88, 95% CI 0.82 to 0.96; OR 0.88, 95% CI 0.80 to 0.96; OR 0.86, 95% CI 0.77 to 0.97, respectively) and revealed a new risk haplotype associated with the same groups of patients (OR 1.14, 95% CI 1.03 to 1.26; OR 1.20, 95% CI 1.08 to 1.35; OR 1.23, 95% CI 1.07 to 1.42, respectively). Conclusions The data confirm the influence of TNFSF4 polymorphisms in SSc genetic susceptibility, especially in subsets of patients positive for lcSSc and ACA.
