- The aim was to investigate the predictive validity of the Worker Role Interview (WRI) for return to work at a 2-year follow-up of clients who attended an insurance medicine investigation center. The WRI identifies psychosocial and environmental factors that influence a person's abilities to return to work. Forty-eight of 202 consecutively selected clients constituted the study group. The Mann–Whitney U test was used to test the statistically significant differences in WRI ratings between those who were working (n=6) and those who were not (n=42) 2 years after their investigations. Five of the 17 items in WRI had a tentative predictive validity of return to work. The content area personal causation in WRI, had the best predictive validity. The results emphasize the importance of considering the unique individual's beliefs and expectations of his/her effectiveness at work when assessing clients' work ability and planning for further rehabilitation.

- Objective: To investigate the clinical logistics of laboratory routines at primary health care centres (PHCs). Design and methods: Prospective registration was carried out for each PHC using questionnaires during 2-week intervals between the end of November 2001 and mid-January 2002. The study included 9 PHCs in the county of Östergötland and 4 in the county of Jönköping, Sweden, with different numbers of blood tests analysed using point-of-care testing (POCT). Data for B-glucose, HbA1c, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), thyroid-stimulating hormone (TSH), T4, cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides were collected. Main outcome measures were median time from sampling to available test result (TATa) and median time from sampling to clinical decision (TATd), and the proportion of patients informed of the outcome of the blood test in question during the sampling occasion. Results: A total of 3542 samples were collected. The median TATa showed that B-glucose, ESR and CRP were immediately analysed at all 13 PHCs. For the other tests, TATa varied from immediately to about two days. The median TATd varied from immediately to about a week. When POCT was used, 30% of the patients were informed about the outcome of the test during the sampling occasion. Conclusion: POCT has a limited effect on the clinical logistics in PHCs.

Attached Bacterial Communities in Lakes – Habitat-Specific Differences
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- For many years, the importance of microorganisms attached to surfaces in littoral zones and wetlands has been disregarded when describing aquatic ecosystem dynamics. Supporting evidence is scarce but convincing that these microbial communities are not only very productive but can often serve as major regulators of nutrient and carbon dynamics in many freshwaters. In order to determine the quantitative importance of epiphytic bacteria for the overall carbon turnover, I compared the relative contribution of epiphytic bacteria on the submerged macrophyte Ranunculus circinatus, sediment and free-living bacteria to the total bacterial production. Sediment bacteria generally dominated total bacterial biomass in the littoral zone. Although the epiphytic biomass on R. circinatus was ten times lower than the biomass of sediment bacteria, it often contributed at least equally to the total bacterial production. Thus, the results presented in this thesis confirm that most bacterial biomass and production in shallow lakes is associated with surfaces, and that in littoral zones with dense macrophyte stands, epiphytic bacteria can contribute significantly to the overall carbon turnover. There is increasing evidence that not all cells in natural bacterial communities are metabolically active. In Lake Erken, there were large differences in the fraction of active bacteria between different habitats, while the within-habitat differences were small. The sediments had the largest bacterial fraction, followed by epiphytic bacteria, while in the water column only a few percent of the bacteria were active. In this thesis the fraction of active bacteria is connected to environmental fluctuations. I hypothesize that smaller fluctuations in chemical, biological or physical factors result in large active bacterial fractions. Thus, small environmental fluctuations within a habitat allow large active bacterial fractions, while the active fraction is constrained when the environmental fluctuations are large.
