- Objective: To evaluate the presence of recall bias in retrospective studies of physical activity and myocardial infarction. Study Design and Setting: In 2005, seventy-eight cases who had suffered from a myocardial infarction and 243 control subjects, who had previously participated in the Swedish WOLF (Work, Lipids, and Fibrinogen) study, were asked about their physical activity level during 1990-2005. The answers about recalled past leisure time, occupational, and household physical activity level were compared with physical activity level as reported at the baseline examination of the WOLF study in 1992-1998. Results: The proportion who recalled the same activity level as originally reported ranged from 69% to 96% (cases) and 69% to 89% (controls), and the kappa values ranged from 0.30 to 0.91 (cases) and 0.46 to 0.59 (controls), with the exception of perceived physical workload in household work, which showed low agreement between the originally stated and later recalled activity levels. Some differences were found between cases and controls regarding recall of past occupational activity, indicating the presence of recall bias in this domain of physical activity. Conclusion: We cannot preclude the existence of recall bias when using retrospectively recalled information about occupational physical activity in studies of physical activity and myocardial infarction.

- OBJECTIVE: To determine whether a nurse-led support and education programme for spouses of patients affected by stroke improved the psychological health of the spouses.DESIGN: A longitudinal, open, randomized controlled trial.SAMPLE: One hundred spouses of stroke patients were randomly assigned to either an intervention or a control group.SETTING: The study was conducted in a hospital setting.INTERVENTION: The intervention consisted of six group meetings during six months, with a follow-up after further six months. Comparison between the intervention and the control groups was made at baseline, after six and 12 months using analysis with repeated measures.MAIN MEASURES: The Comprehensive Psychopathological Rating Scale--Self-Affective for psychological health.RESULTS: No significant difference was found between the intervention and control groups concerning overall psychological health. However, a subanalysis revealed that those who participated more frequently in the group meetings (five or six times) had significantly stronger psychological health (P<0.05). Knowledge about stroke increased over time in both groups, but participants in the intervention group learned more (P=0.041).CONCLUSION: Encouraging participation in the group meetings of a support programme might have a positive effect on psychological health.

- AIM: The aim of this study was to examine predictors of the life situation of the significant other of depressed or aphasic stroke patients.BACKGROUND: Depression and aphasia are common consequences of stroke, and both may put pressure on the significant other who have to deal not only with a possible physical handicap but also with communication and/or serious psychiatric difficulties.DESIGN: Descriptive, cross-sectional study.METHODS: The participants were significant others of 71 depressed and 77 aphasic stroke patients. Depression was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorder, and degree of aphasia was diagnosed with the Amsterdam Nijmegen Everyday Language Test. Assessments of the life situation, state of depression and aggression, personality change and need of assistance were made through questionnaires issued to the significant others.RESULTS: Perceived need of assistance was the only common predictor of life situation of the significant other in both groups (p < 0.001). With respect to the aphasic patients, perceived personality change (p < 0.001) and living with the patient (p = 0.004) were factors that had a negative effect on the life situation of the significant other.CONCLUSIONS: This study highlights that the perception of the patient's need of assistance is an important factor in predicting the life situation among spouses of depressed as well as aphasic stroke patients. A comparison of the two groups to explain the life situation of the significant others revealed greater explanatory power for the aphasic group.RELEVANCE TO CLINICAL PRACTICE: Assessments of the spouses' perception as well as of the patients' factual situation may identify those significant others at risk. With this new approach, necessary steps may be taken to alleviate pressure on the significant other.

- Spider silk is an interesting biomaterial for medical applications. Recently, a method for production of recombinant spider silk protein (4RepCT) that forms macroscopic fibres in physiological solution was developed. Herein, 4RepCT and MersilkTM (control) fibres were implanted subcutaneously in rats for seven days, without any negative systemic or local reactions. The tissue response, characterised by infiltration of macrophages and multinucleated cells, was similar with both fibres, while only the 4RepCT-fibres supported ingrowth of fibroblasts and newly formed capillaries. This in vivo study indicates that 4RepCT-fibres are well tolerated and could be used for medical applications, e.g., tissue engineering.

Tidskriftsartikel (refereegranskat)abstract
- The phenomenon of world-wide immigration and migration has major implications for the health of the migrants in addition to its impact upon social and other service providers. Studies of migrants that utilize social epidemiologic methods fall within the traditional boundaries of descriptive and analytic approaches; this article reviews some of the studies that exemplify these approaches. It then suggests specific methodological issues and cautions pertaining to research on migrants and provides a theoretical model for organizing the diverse research studies that have been conducted. By stimulating discussion regarding social epidemiologic research on migrants' health, this model is intended to serve as a compass point for future research and needed interventions.

- Background Internet-delivered self-help programmes with added guidance have shown efficacy in social anxiety disorder, unguided self-help has been insufficiently studied. Aims To evaluate the efficacy of guided and unguided self-help social anxiety disorder. Method Participants followed a cognitive-behavioural self-help programme in the form of either pure bibliotherapy or an internet-based treatment with therapist guidance and online group discussions. A subsequent trial was conducted to evaluate treatment specificity. Participants (n=235) were randomised to one of three conditions in the first trial, or one of four conditions in the second. Results Pure bibliotherapy and the internet-based treatment were better than waiting list on measures of social anxiety, general anxiety, depression and quality of life. The internet-based therapy had the highest effect sizes, but directly comparable effects were noted for bibliotherapy augmented with online group discussions. Gains were well maintained a year later. Conclusions Unguided self-help through bibliotherapy can produce enduring improvement for individuals with social anxiety disorder.

- BACKGROUND: Fetal screening for Down syndrome by an ultrasound examination, including measurement of fetal nuchal translucency, at 12 to14 weeks' gestation is presently being evaluated in a Swedish randomized controlled trial. Women at high risk were offered an amniocentesis to obtain a definite diagnosis. The aim of this study was to explore women's reactions and responses to information about being at high risk after the scan, with a special focus on reactions to a false positive test. METHOD: Interviews were conducted with 24 women within 1 week after the scan, in midpregnancy, and 2 months after the birth. The interviews were analyzed qualitatively. Down syndrome was confirmed in 4 women, who chose to terminate the pregnancy. The remaining 20 women had a false positive test. RESULTS: For the majority, the risk information caused strong reactions of anxiety and worries about the future. A typical way for women to cope was to "withhold" the pregnancy, to take a "timeout," and try to live as if they were not pregnant any longer. Some weeks later, when the women received normal results from the chromosome analysis, they resumed being pregnant. Six women ages more than 35 years who had a risk score lower than their age-related risk did not express similarly strong reactions. Two months after the birth of a healthy baby, most stated they would undergo the same procedure in a subsequent pregnancy. One woman still suffered from the experience when interviewed at 2 months after the birth, and another said she regretted participating in the fetal screening program. CONCLUSIONS: A false positive test of fetal screening for Down syndrome by ultrasound examination may cause strong reactions of anxiety and even rejection of the pregnancy. The prevalence of such reactions and possible long-term effects need further investigation.
