- There is evidence that complement components may be formed locally in inflammatory lesions containing monocytes and macrophages. To investigate the role of complement in Crohn's disease we measured jejunal-fluid concentrations of the complement components C4, C3, and factor B by perfusion of a closed segment of the jejunum in 22 patients with Crohn's disease thought to be limited to the terminal ileum.The mean (±SEM) jejunal-fluid C4 concentration was 2.0±0.3 mg per liter, significantly higher than the mean level in 35 healthy controls (0.7±0.1 mg per liter; P<0.001). The mean C3 concentration was 1.0±0.1 mg per liter in the patients and 0.7±0.1 mg per liter in the controls (P<0.05). The factor B levels were similar in the two groups. Calculated rates of intestinal secretion of these components showed differences of the same magnitude. Leakage of protein from plasma was not increased. The jejunal-fluid serum ratios of these complement proteins indicated that their appearance in the lumen of the jejunum was due at least in part to local mucosal synthesis. The increased jejunal secretion of C4, but not C3 or factor B, paralleled the clinical activity of Crohn's disease. Values were normal in first-degree relatives of the patients (n = 13), patients with celiac disease (n = 8), and patients with ulcerative colitis (n = 4).We conclude that increased secretion of complement by clinically unaffected jejunal tissue in patients with Crohn's disease reflects the systemic nature of this disorder and may be due to the stimulated synthesis of complement by activated intestinal monocytes and macrophages.

Tidskriftsartikel (refereegranskat)abstract
- In public health contexts, increased physical activity habits and fitness (aerobic and strength capacities) are positively related for promoting health and preventing and treating common diseases/problems, including obesity and overweight. A strongly graded inverse association between physical activity and obesity has been shown both for adults and children. However, a lower mortality risk has been shown for those with greater weight but good aerobic capacity than for those of recommended weight but less fit. On the basis of a health project with physical activity for persons with or without obesity, the paper discusses evidence-based methods for promoting physical activity. General guidelines for the amount of physical activity for persons are described, as are the numerous physiological and medical advantages of physical activity. The economic benefits are also illustrated. The paper exemplifies methods of measuring physical activity habits and physical fitness. These two factors must be observed when showing improvements in public-health contexts, including groups with obesity.

- En god kondition och styrka har samband med förbättrad hälsa, minskad förekomst av flera folksjukdomar samt ökad livslängd. Fysiologiska tester kan vara stimulerande för äldre att följa utvecklingen av sin fysiska kapacitet och för olika aktörer som vill göra hälsoutvärderingar.

Improved Physical Capacity in a Project with Guided Physical Activity for Persons with Depression or Anxiety.
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Background: Higher physical capacity is correlated with increased health. Knowledge in this area regarding psychiatric diseases is sparse. Purpose: The aim was to study aerobic and several strength capacities in a physical activity project for persons with depression or anxiety. Methods: Eighty-four persons (56 women and 28 men) with depression or anxiety were recruited from psychiatric out-patient clinics in Stockholm. Their mean age and BMI was 46 (21-80) years and 26 (17-41) kg/m2, respectively. 50% were sick-listed. 50% had BMI>25. Aerobic and strength tests were chosen by each subgroup´s project leaders. Directed physical activity was given, in groups 10-15, 1 hour twice/week during 8-12 weeks. Results: Significant changes (p<0.05, of all n=84) between pre- and post tests were seen in submaximal cycle test (11% enhanced values, n=56) and distance of 6 minutes walk test (16%, n=15) as well as in strength tests for the back for the back (i.e. time in static horizontal belly-back, 40%, n=44), abdominal and hip flexors (i.e. number of hip flexion sit-ups, 45%, n=38), leg (i.e. standing with 90O in hips and knees, 48%, n=56) and arm with shoulder muscles (i.e. number of raising weights alternately with the arms, 46%, n=32). Hand grip tests, BMI or blood pressure values did not change significantly. Conclusions: Directed 8-12 weeks physical activity programs can improve physical fitness in individuals with depression or anxiety.

- OBJECTIVE:To investigate the prevalence of urinary incontinence in a representative population in Sweden, and to assess to what extent the condition affects daily life and to what degree those afflicted desire treatment.MATERIAL AND METHODS:In a population-based study, a postal questionnaire comprising 12 questions on urinary incontinence was sent to a representative sample of 15 360 randomly selected residents (aged 18-79 years) of Orebro County, Sweden. This was a supplement to a comprehensive survey of public health and general living conditions.RESULTS:The response rate was 64.5%. The prevalence of urinary incontinence was 19% when defined as "any leakage" and 7% when defined as "at least once a week". Women were more afflicted than men, and the proportion of people with urinary incontinence increased markedly with increasing age. Most considered their problems to be minor, having little impact on daily life, which was reflected by the fact that only 18% of those with urinary incontinence desired treatment. About 17% of those with urinary incontinence reported severe problems that interfered with daily life. Of respondents with severe problems, 42% did not want treatment.CONCLUSION:According to this population-based study, urinary incontinence is not a major problem for most people in the community. Although a considerable proportion of the population report urinary incontinence, the majority experience minor problems and only 18% desire treatment. For a limited group of people, urinary incontinence is a severe problem. It is important that healthcare resources are optimized to identify and meet the needs of those who are most afflicted.
