- In two independent human cohorts, the minor allele of SNP rs3850641 in TNFSF4 was significantly more frequent in individuals with myocardial infarction than in controls. In mice, Tnfsf4 expression is associated with increased atherosclerosis. The expression of TNFSF4 in human atherosclerosis and the association between genotype and cerebrovascular disease have not yet been investigated. TNFSF4 messenger RNA (mRNA) levels were significantly higher in human atherosclerotic lesions compared with controls (730∈±∈30 vs 330∈±∈65 arbitrary units, p∈<∈0.01). TNFSF4 was mainly expressed by macrophages in atherosclerotic lesions. In cell culture, endothelial cells upregulated TNFSF4 in response to tumor necrosis factor alpha (TNF-α; 460∈±∈110 vs 133∈±∈8 arbitrary units, p∈<∈0.001 after 6 h of stimulation). We analyzed the TNFSF4 gene in 239 patients who had undergone carotid endarterectomy and 138 matching controls from The Biobank of Karolinska Carotid Endarterectomies and Stockholm Heart Epidemiology Program cohorts and 929 patients and 1,382 matching controls from the Sahlgrenska Academy Study on Ischemic Stroke and Case Control Study of Stroke cohorts, limiting inclusion to patients with ischemic stroke. Participants were genotyped for the rs3850641 SNP in TNFSF4. Genotype associations were neither found with TNFSF4 mRNA levels nor with atherosclerosis associated systemic factors or risk for stroke. This study shows that TNFSF4 is expressed on antigen-presenting cells in human carotid atherosclerotic lesions but provides no evidence for an association of TNFSF4 gene variation with the risk for ischemic stroke.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Few studies have evaluated dipstick urinalysis for elderly and practically none present confidence intervals. Furthermore, most previous studies combine all bacteria species in a "positive culture". Thus, their evaluation may be inappropriate due to Yule-Simpson's paradox. The aim of this study was to evaluate diagnostic accuracy of dipstick urinalysis for the elderly in nursing homes. METHODS: In this cross-sectional study voided urine specimens were collected from 651 elderly individuals in nursing homes. Dipstick urinalysis for nitrite, leukocyte esterase and urine culture were performed. Sensitivity, specificity, positive and negative predictive values with 95% confidence intervals were calculated. Visual readings were compared to readings with a urine chemistry analyzer. RESULTS: 207/651 (32%) of urine cultures showed growth of a potentially pathogenic bacterium. Combining the two dipsticks improved test characteristics slightly compared to using only one of the dipsticks. When both dipsticks are negative, presence of potentially pathogenic bacteria can be ruled out with a negative predictive value of 88 (84-92)%. Visual and analyzer readings had acceptable agreement. CONCLUSION: When investigating for bacteriuria in elderly people at nursing homes we suggest nitrite and leukocyte esterase dipstick be combined. There are no clinically relevant differences between visual and analyzer dipstick readings. When dipstick urinalysis for nitrite and leukocyte esterase are both negative it is unlikely that the urine culture will show growth of potentially pathogenic bacteria and in a patient with an uncomplicated illness further testing is unnecessary.

Tidskriftsartikel (refereegranskat)abstract
- Background. Long-standing pelvic pain during pregnancy and after delivery (PPP) is common. Its causes are not fully understood. A scientifically, undocumented, clinical observation is PPP patients often reporting unspecific abdominal pain and adverse reactions to milk. The main objective in this pilot study was to investigate if lactose intolerance, celiac disease or allergic propensity are risk factors for developing pelvic pain after delivery. Methods. A matched, case control study, where consecutive patients consulting a registered physiotherapist specialised in treating women with postpartum pelvic pain were compared to matched controls. Results. Lactose intolerance was found in 10 of 15 patients, and in 3 of 15 matched, healthy controls (p=0.05). No difference was seen between groups in the prevalence of celiac disease or allergic propensity. Conclusion. This study suggests that lactose intolerance might be a possible risk factor for pelvic pain after delivery.

- BackgroundStudies have revealed low adherence to guidelines for treatment of diabetes and cardiovascular risk factors.ObjectiveTo explore general practitioners’ experiences regarding treatment practice in type 2 diabetes with specific focus on the prevention of cardiovascular disease.MethodsFourteen experienced general practitioners from nine health care centres with group practices were interviewed in focus groups. The interviews were digitally recorded, transcribed verbatim and analysed by qualitative content analysis.ResultsThe overall theme was “dilemmas” in GPs´ treatment practice for type 2 diabetes patients. Five main dilemma categories were identified. First, the GPs were hesitant about labelling someone who feels healthy as ill. Secondly, regarding communicating a diabetes diagnosis and its consequences; should the patient be frightened or comforted? Thirdly, the GPs experienced uncertainty in their role; were they to take responsibility for the care or not? Fourthly, the GPs expressed a conflict between lifestyle changes and drug treatment. Fifthly, the GPs described difficulties in integrating science into reality.ConclusionsThe five dilemmas in the general practitioners’ approach to diabetes patients and the treatment of their cardiovascular risk were related to the GPs´ professional role and communication with the patient. To consider these dilemmas in educational efforts is probably essential to achieve improved diabetes care and guideline adherence.

Studies of Secondary Prevention after Coronary Heart Disease with Special Reference to Determinants of Recurrent Event Rate
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objectives. The first aim was to examine the effects of secondary prevention with a focus on determinants in the risk of recurrent coronary heart disease (CHD). The second aim was to analyse the effects of a cognitive behavioural therapy (CBT) intervention on the risk of recurrent cardiovascular disease (CVD) and to investigate the psychosocial situation of CHD patients. Material and methods. Papers I and II were based on the Swedish Acute Myocardial Infarction Statistics Register, 1969 to 2001: 775,901 events in 589,341 subjects. Papers III and IV were based on The Secondary Prevention in Uppsala Primary Care project (SUPRIM), a randomized controlled clinical trial in 362 CHD patients. Results. The risk of a recurrent acute myocardial infarction (AMI) event was highly dependent on time from the previous event, with the greatest risk immediately after an AMI event. In addition, sex, age, and AMI number influenced the general risk level. Furthermore, there has been a major decline in recurrence risk over 30 years, and there were considerable geographical differences in risk, best explained by residential area population density, with a high recurrent AMI risk in areas with the lowest and the highest population densities, and the lowest risk in areas with moderate population density. Disease status and sex were determinants of psychological well-being the first year after a CHD event. Sex seemed to be the stronger determinant. The CBT intervention focused on stress management during one year in patients with CHD. There was significantly improved outcome in the intervention group on recurrent CVD and recurrent AMI during a 9 year follow up. A dose-response relationship was demonstrated between attendance rate at intervention group meetings and outcome, the higher the attendance rate the better the outcome. Conclusions. The risk of a recurrent AMI event was dependent on time from the previous event, with major improvement seen in recent decades. Regional differences were best explained by population density. Female CHD patients were at high risk concerning well-being after a coronary event, which deserves special attention. The CBT intervention for CHD patients improved outcomes concerning the risk of recurrent CVD and AMI events.

Struggling for clarity : cultural context, gender and a concept of depression in general practice
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Many depressed patients attend primary health care, and minority-group patients often see general practitioners for depressive symptoms. The diagnosis and classification criteria of depression and guidelines for management are based on symptoms. However,expressions of depression can vary with culture and gender but the diagnostic tools and guidelines are not adapted to gendered or cultural context and have shown to be poorly applicable in clinical practice. The purpose of this thesis was to analyse how socio-cultural factorswith focus on gender and ethnicity and their intersections- could influence the concept of depression from the perspectives of the patient and patient descriptions, of medical experts as well as general practitioners. By viewing these different perspectives I have tried to illustrate how depressive symptoms are expressed and interpreted in different gendered socio-cultural contexts and how they become a disease entity. Furthermore, I want, in particular, to illustrate a variety of difficulties that GPs may face during the process of care when meeting and treating men and women from different countries showing symptoms which may indicate depression. Study I. The aim of the study was to explore the reasons for and patterns of attendance among Roma women in primary health care and to shed light on health problems of the Roma. Four Roma women were interviewed in-depth. The data were audiotaped and analysed according to Grounded Theory. The resuIts showed that the daily life of women was characterized by marked hierarchical order and rules formed by gender, age and the collective culture. Young women had most rules to follow and if the rules were broken it was easy to end up outside the collective and display depressive symptoms or pain. The gendered, collective culture could both construct and/or form the concept of illness among the Roma women. Study II. The aim of the study was to highlight the gendered representations of lay persons´ experiences of depression by drawing on personal stories of depression that appeared in Swedish newspapers. The data were then subjected to a Qualitative Content Analysis. The mediated accounts of depression both upheld and challenged traditional gender stereotypes. The women’s stories were more detailed, relational, emotionally oriented, and embodied. The portrayal of men was less emotional and expressive, reflecting hegemonic patterns of masculinity. The media representations of gendered healthrelated beliefs and behaviours may influence the way patients, physicians and other health care professionals understand and communicate about issues of mental health and depression. Study III. The aim of the study was to explore how authors of medical articles wrote about different symptoms and expressions of depression in men and woman from various ethnic groups as well as to analyse the meaning of gender and ethnicity for expressions of depression. Through a search in the medical database PubMed 30 scientific articles were identified and included in the analysis. The result and the discussion section of each article was analysed with Qualitative Content Analysis. The analysis showed that culture and gender formed the expressions of depression, how depression was interpreted and the diagnosis of depression. The analysis of the articles identified a western point of view, which could lead to “cultural or gender gaps” and which could also influence the diagnosis of depression. Study IV. The aim of the study was to make a qualitative analysis of medical research articles in order to get a broader view of explanations of depression in men and women in various ethnic groups. Through a search in the medical database PubMed 60 scientific articles were identified and included in the analysis. The result and the discussion section of each article was analysed with Qualitative Content Analysis. The explanations for depression in our study have a strong emphasis on socio-cultural causes with focus on depressed persons from non-western minority groups. Even so, discussion about cultural or gendered explanations for depression was almost missing. We interpreted that the view of minority groups in the articles could be described as a view of “others”. The view of “othering” increases risks for cultural and gender gaps, such as biased scientific knowledge, medicalization of social problems, cultural stereotypes, risk for misdiagnosis of men´s depression, and affects the quality and care of depressed patients. Studv V. The aim of the study was to explore and analyse how GPs think and deliberate when seeing and treating patients from foreign countries who display potential depressive symptoms. The data were collected in focus group and individual interviews with GPs in northern Sweden and analysed by Qualitative Content Analysis. The study showed that patients’ early life events of importance were often unknown which blurred the accuracy. Reactions to trauma, cultural frictions and conflicts between the new and old gender norms made the diagnostic process difficult. The patient-doctor encounter comprised misconceptions, and social roles in meetings were sometimes confused. GPs based their judgement mainly on clinical intuition. Tools for management and adequate action were diffuse. There is a need for tools for multicultural, general practice care. It is also essential to be aware of the GPs’ own conceptions to avoid stereotypes and not to under-or overestimate the occurrence of depressive symptoms. Conclusion: The concept of depression is always situated. The gendered socio-cultural norms, beliefs and behaviours can both construct the concept of illness and influence patients’ experiences and expressions of depression as well as form the patient-doctor encounter. The knowledge of medical “experts” is based on a dominating, western view of knowledge, which defines diagnosis and classification criteria of depression as well as guidelines for management. GPs are struggling for clarity between the medical and the clinical practice. The multicultural appearances of depressive symptoms are a challenge for GPs but it is a challenge for society to improve the life circumstances which can lead to a depressed mood and suffering.

Beyond the established risk factors of myocardial infarction : lifestyle factors and novel biomarkers
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Age, male sex, hypertension, smoking, diabetes, dyslipidaemia, and obesity are considered as established risk factors for cardiovascular diseases. Several of these established cardiovascular risk factors are strongly influenced by lifestyle. Novel biomarkers from different mechanistic pathways have been associated with cardiovascular risk, but their clinical utility is still uncertain. The overall objective of the thesis was to evaluate the associations between certain lifestyle factors (physical activity and snuff use), biomarkers reflecting the haemostatic and the inflammatory systems and risk of a future first-ever myocardial infarction. A prospective incident nested case-control study design was used with a total of 651 cases of myocardial infarction and 2238 matched controls from the population-based Northern Sweden Health and Disease Study. The effects of commuting activity, occupational and leisure time physical activity on risk of myocardial infarction were studied. A clearly increased risk of myocardial infarction was found for car commuting compared to active commuting (walking, cycling or going by bus). High versus low leisure time physical activity was associated with decreased risk of myocardial infarction. Low occupational physical activity was associated with risk of myocardial infarction in men. The risk of myocardial infarction or sudden cardiac death was studied in male snuff users compared to non-tobacco users. No increased risk was found for myocardial infarction or sudden cardiac death among snuff users without a previous history of smoking. However, for sudden cardiac death the study did not have statistical power to detect small differences in risk. Plasma levels of haemostatic markers have previously shown to be associated with risk of myocardial infarction, but as haemostatic markers are also acute-phase reactants, it is not clear if their association with myocardial infarction is independent of inflammatory markers. In the present study, the haemostatic markers D-dimer, von Willebrand factor (VWF), tissue plasminogen activator (t-PA), and tissue plasminogen activator/plasminogen activator inhibitor-1 complex (t-PA/PAI-1 complex) were associated with risk of myocardial infarction after adjustment for established risk factors and the inflammatory markers C-reactive protein (CRP) and interleukin 6 (IL-6). Furthermore, the addition of eight haemostatic and inflammatory markers could improve the predictive ability for future myocardial infarction beyond that of a model utilizing only established risk factors. Established risk factors and novel biomarkers were explored as potential mediators of the reduced risk of myocardial infarction related to active commuting. A combination of established risk factors, haemostatic and inflammatory markers appeared to explain a substantial proportion (40%) of the difference in risk for myocardial infarction between active commuters and car commuters. IL-6, t-PA, t-PA/PAI-1 complex, apo B/apo A-1 ratio, and BMI seemed to be the largest potential mediators when tested individually. In conclusion, regular physical activity such as active commuting is associated with reduced risk of a first-ever myocardial infarction. This effect could in part be mediated through a beneficial influence on haemostasis and inflammation, as well as a positive impact on established risk factors. Several haemostatic markers are associated with risk of myocardial infarction independent of established risk factors and inflammatory markers. The combination of haemostatic and inflammatory markers may enhance predictive ability beyond established risk factors. Our findings do not support the hypothesis that snuff use increases the risk of myocardial infarction.

Towards Understanding of Determinants of Physicians’ Sick-listing Practice and their Interrelations : A Population-based Epidemiological Study
- 2003
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Physicians are supposed to act as sick-listing experts and they possess a role as gate-keepers to the social insurance system. Earlier studies have demonstrated variation between physicians and physician categories regarding sick-listing practice. In addition to the patient's disease and its severity, a number of other factors may be expected to influence sick-listing practice. Most earlier studies have focused on the patient's disease and his or her work place as cause for sickness absence.The aims of this study were to analyse variation of sick-listing practice between physician categories and the influence of physician characteristics on sick-listing practice, the influence of structure, organisation and remuneration of health care on physician sick-listing practice, the influence of local structural factors in the community, and the influence of a legislative change on physician sick-listing practice.The study was conducted as a cross-sectional epidemiological study of 57563 doctors’ certificates for sickness absence, received by 28 local social insurance offices in eight Swedish counties, during four months in 1995 and two months in 1996.Patient age, sex, and diagnostic group, issuing physician category, presence of a hospital in the municipality, municipality population size and county were all significantly and independently correlated to number of net days of sick-listing. Physician characteristics, such as age, sex and degree of specialisation were all associated with number of net days of sick-listing. Physicians working in general practice issued significantly shorter periods of sick-listing than the other physician categories. Reimbursement of general practice and participation in financial co-operation with social insurance were significantly correlated to length of sickness episode issued by general practitioners. A legislative change performed during the study period was associated with small effects in sick-listing practice.In conclusion, a number of factors other than disease and disease severity and other patient and physician linked factors were found to influence the variation of sick-listing practice. It appears that the closer the influencing factor was to the place were the decision was taken, i.e., the patient-physician consultation, the higher the impact on the decision appeared to be.
