The infection route of Flavobacterium psychrophilum into rainbow trout Oncorhynchus mykiss was studied using bath and cohabitation challenges as well as oral challenge with live feed as a vector. Additionally, the number of bacterial cells shed by infected fish into the surrounding water was determined in the cohabitation experiment and in challenge experiments at 3 different water temperatures. The experiments showed that skin and skin mucus abrasion dramatically enhanced the invasion of F. psychrophilum into the affected fish in bath and cohabitation challenges. Disruption of the skin is discussed as an important invasion route for F. psychrophilum into the fish. The shedding rate of F. psychrophilum by infected fish was associated with water temperature and the mortality of the infected fish. High numbers of F. psychrophilum cells were released into the water by dead rainbow trout during a long time period compared to the numbers of cells shed by live fish. The results emphasise the importance of removing dead and moribund fish from rearing tanks in order to diminish the infection pressure against uninfected fish in commercial fish farms. In immunohistochemical examinations of organs and tissues of orally infected fish, F. psychrophilum cells were detected in only 1 fish out of 31 studied. Mortality of the orally challenged fish was not observed in the experiment.

Health can be viewed from several perspectives. It has been shown that impingement of the shoulder leads to functional inability and decreased life quality. The aim of this study was to investigate the complexity of the effect of shoulder problems and discern and describe what it entails to be a patient suffering from shoulder problems. The study delineated patients' situations prior to and following medical intervention. This study is qualitative, and the data were collected through focus group interviews. Interviews with 26 respondents aged 43-63 (mean age 53) were made in 2005-2007. The sample group consisted of patients with supraspinatus tendinitis receiving either conservative treatment or surgery. Thematic analysis was used. Meaning units or themes were identified and interpreted in context and related to the ICF model and Antonovsky's theory for the factors capable of affecting health. Prior to intervention, pain was the attribute most strongly associated with shoulder problems. Four clear focus categories, all of which contain a dimension of pain, were identified. Postintervention interviews permitted data analysis from two main perspectives: 1) process and 2) result. Patients should feel part of the care process and their experience should include comprehensibility, manageability, and meaningfulness. A supportive environment helps ensure such, allowing for a successful rehabilitation process.

BACKGROUND: Occupational self-efficacy (OSE) is an appropriate adaption capability to react to continuous changes in work life today. While self-efficacy is an important component in work context, there is less knowledge regarding older workers’ OSE. OBJECTIVE: This study examined the relationship between work ability, OSE and work engagement among a middle-aged workforce, and whether there were any differences between age groups and between professionals in different work context. METHODS: Data were collected by questionnaire, which included Work Ability Index (WAI), Occupational Self-Efficacy Scale, and Utrecht Work Engagement Scale. RESULTS: A total of 359 home care workers and engineers (response rate 43%) participated. The average age was 54 (SD±5.3) years, 69%were women. The results of logistic regression analyses revealed an association between WAI, OSE (OR 0.66; 95%CI 0.52 to 0.86) and work engagement (OR 0.61; 95%CI 0.47 to 0.78). Higher OSE and work engagement were related to higher work ability. No difference in OSE (5.9; ±0.8) between professional groups was seen, but the home care workers scored considerably higher work engagement (5.1; ±0.9) than the engineers (4.5; ±1.3). CONCLUSIONS: Improving OSE could be worthwhile to support work ability among middle-aged workers, despite dissimilarities in work context and educational level.
