Abstract: OBJECTIVE: To assess the intra and interobserver reproducibility of musculoskeletal ultrasonography (US) among rheumatologists in detecting destructive and inflammatory shoulder abnormalities in patients with rheumatoid arthritis (RA) and to determine the overall agreement between US and MRI. METHODS: A total of 14 observers examined 5 patients in 2 rounds independently and blindly of each other. US results were compared with MRI. Overall agreement of all findings, of positive findings on MRI, as well as intra and interobserver reliabilities, were calculated. RESULTS: Overall agreement between US and MRI was seen in 79% with regard to humeral head erosions (HHE), in 64% with regard to posterior recess synovitis (PRS), in 31% with regard to axillary recess synovitis (ARS), in 64% with regard to bursitis, in 50% with regard to biceps tenosynovitis (BT), and in 84% for complete cuff tear (CCT). Intraobserver and interobserver kappa was 0.69 and 0.43 for HHE, 0.29 and 0.49 for PRS, 0.57 and 1.00 for ARS, -0.17 and 0.51 for bursitis, 0.17 and 0.46 for BT and 0.52 and 0.6 for CCT, respectively. The intraobserver and interobserver kappa for power Doppler (PD) was 0.90 and 0.70 for glenohumeral signals and 0.60 and 0.51 for bursal signals, respectively. CONCLUSIONS: US is a reliable imaging technique for most shoulder pathology in RA especially with regard to PD. Standardisation of scanning technique and definitions of particular lesions may further enhance the reliability of US investigation of the shoulder.

Abstract: To evaluate the role of purpose in life among people with rheumatoid arthritis (RA), a questionnaire comprising the Purpose in Life test (PIL) and the purpose in life dimension of the Psychological Well-Being test (PWB-pil) was sent to a random sample of 300 patients with RA. Additional questions comprised sociodemographic and disease characteristics, physical, mental and social functioning, coping (Coping with rheumatic stressors questionnaire), and quality of life (RAND-36). Associations between sociodemographic and disease characteristics, physical, mental and social functioning, and coping on the one side and the two measures of purpose in life on the other side and associations between the two purpose of life measures and physical and mental dimensions of quality of life were assessed by means of univariate and multivariate regression analyses. The response rate was 156 of 300 (52%). The median PIL and PWB-pil scores were 103 (range 63-131) and 82 (41-110), respectively. A lower age, a better mental health status, and an optimistic coping style were significantly associated with both higher PIL and PWB-pil scores, whereas more participation in leisure and/or social activities was associated with a higher PIL score. It was found that the PIL and PWB-pil contributed independently and significantly to the mental component summary scale of the RAND-36. In RA patients, lower age, a better mental health status, an optimistic coping style, and participation in leisure and/or social activities were significantly associated with more sense of purpose in life. Purpose in life pays a significant and independent contribution to the mental component of quality of life. These findings highlight the significance of the concept of purpose in life in patients with RA.

Abstract: OBJECTIVES: To study the occurrence and duration of sick leave as potential risk factors for permanent job loss after 24 months among 112 individuals with chronic arthritis and a disease related problem at work. METHODS: Data collection was embedded in a multicentre randomised controlled trial in which the cost-effectiveness of a multidisciplinary job retention vocational rehabilitation programme for employees with chronic arthritis and a disease related problem at work was compared to usual outpatient care. Sick leave (complete or partial) was defined as absenteeism reported to the employer and permanent job loss as receiving a full work disability pension or unemployment. The association between sick leave at baseline and job loss after 24 months was investigated by multivariate logistic regression analysis, including those variables that were univariately significantly associated with job loss after 24 months. RESULTS: At baseline, 60 of the 112 subjects (54%) were on sick leave, with a mean duration of 18.7 weeks, in half of these patients the sick leave was complete. After 24 months, 26 of the 112 patients (23%) had lost their job. The presence of complete sick leave (OR 4.74, 95% CI 1.86-12.07) and the depression score of the hospital anxiety and depression scale (OR 1.18, 95% CI 1.02-1.36) were significantly and independently associated with job loss after 2 years follow-up. CONCLUSION: The occurrence of complete sick leave was found to be an independent risk factor for job loss in patients with chronic arthritis who have a disease related problem at work.
