    • Västra Götalandsregionen har drygt 1,5 miljoner invåna re. Patienter med diagnosen schizofreni (N = 4 593) under juli 2005 till och med decem ber 2009 har studerats. Läkemedelskostnaden var lägre för äldre neuroleptika än för nyare »atypiska« anti psykotika. Sjukhuskostna derna var lika för båda grup perna, medan öppenvårds­ kostnaderna var högre vid behandling med nya medel än med äldre. Totalkostnaden per patient varierade från 243 000 (äldre läkemedel) till 360 000 kro nor (nyare antipsykotika). Samsjukligheten tenderade att vara lägre för aripiprazol, men var lika för äldre och and ra nyare preparat. Sjukskrivningstiderna var lika oberoende av preparat. Dödligheten var 2,4 gånger högre hos schizofrenipatien ter än i totalbefolkningen, men den var inte signifikant lägre vid läkemedelsbehand ling än utan. Dock var den signifikant lägre vid behand ling med nyare antipsykotika än med äldre läkemedel.

  • Gender and regional differences in perceived job stress across Europe
  • 2005
  • Ingår i: Eur J Public Health. - : Oxford University Press. - 1101-1262. ; 15:5, s. 536-45
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Over the last 20 years stress at work has been found to be predictive of several conditions such as coronary heart disease, high blood pressure and non-specific sick leave. The Karasek demand/control/strain concept has been the most widely used in prospective epidemiological studies. OBJECTIVES: To describe distribution in Karasek's demand/control (DC) dimensions as well as prevalence of strain in samples from different parts of Europe grouped into three regions (South, Middle, Sweden), adjusting for occupation. To describe gender differences in Karasek's DC dimensions along with strain prevalence and assess the regional stability of those differences in different occupational groups. DESIGN: The Job stress, Absenteeism and Coronary heart disease in Europe (JACE) study, a Concerted Action (Biomed I) of the European Union, is a multicentre prospective cohort epidemiological study: 38,019 subjects at work aged 35-59 years were surveyed at baseline. Standardised techniques were used for occupation coding (International Standardised Classification of Occupations) and for the DC model (Karasek scale): five items for the psychological demand and nine items for the control or decision latitude dimensions, respectively. RESULTS: A total of 34,972 subjects had a complete data set. There were important regional differences in the Karasek scales and in prevalence of strain even after adjustment for occupational class. Mean demand and control were higher in the Swedish centres when compared to two centres in Milano and Barcelona (Southern region) and values observed in four centres (Ghent, Brussels, Lille and Hoofddorp) in Middle Europe were closer to those observed in the Southern cities than to those obtained in the Swedish cities. Clerks (ISCO 4) and, more specifically, office clerks (ISCO 41) exhibited the smallest regional variation. In a multivariate model, the factor 'region' explained a small fraction of total variance. In the two Southern centres as well as in the four Middle European centres, men perceived marginally less job-demand as compared to women whereas the reverse was observed in the two Swedish centres. Differences were larger for control: men appeared to perceive more control at work than did women. In a multivariate model, gender explained a small fraction whereas occupational level explained a large fraction of the variance. CONCLUSIONS: In this standardised multicentre European study Karasek's DC model showed large gender and occupational differences whereas geographic region explained a small fraction of the total DC variance, notwithstanding large differences in labour market and working conditions as pointed out by the European Commission as recently as 2000.

  • Chromosomal mosaicism mitigates stigmata and cardiovascular risk factors in Turner syndrome.
  • 2007
  • Ingår i: Clinical endocrinology. - 0300-0664. ; 66:5, s. 744-51
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To study genotype-phenotype correlations in Turner syndrome (TS) regarding body composition, cardiovascular risk factors, stigmata and age at diagnosis vs. degree of mosaicism estimated as the percentage of 45,X and 46,XX cells. METHODS: One hundred and twenty-six TS women, mean age 31 years, were examined by three specialists, who reported stigmata independent of each other. Dual energy X-ray absorptiometry (DXA) was used to measure bone mineral density (BMD). The karyotype was blinded. Fluorescence in situ hybridization (FISH) was performed on buccal cells. A random population sample served as controls. RESULTS: Forty-four per cent exhibited a 45,X karyotype and 56% a second-cell line, while 27% of all had a 45,X/46,XX mosaicism. Five 45,X cases with a conventional karyotype were 45,X/46,XX mosaic according to FISH. At diagnosis, 45,X cases were younger (P < 0.05) and had more stigmata per person (P < 0.01) than the mosaics. TS with marker chromosome X or Y, iso or ring, did not differ from 45,X in this aspect. The mosaics had higher BMD and SHBG and lower total cholesterol and FSH than TS with 45,X and did not differ compared with controls in terms of body mass index (BMI), waist/hip ratio, BMD, blood pressure, cholesterol, triglycerides, SHBG, diabetes or osteoporosis. The number of stigmata correlated positively to BMI, waist/hip ratio, cholesterol and %45,X and inversely to height and %46,XX according to FISH. CONCLUSIONS: Mosaicism seems to mitigate the TS phenotype and the cardiovascular risk factor profile. Mosaics were diagnosed 8 years later than 45,X cases. This emphasizes the necessity for a stricter genotype categorization not only in the clinic but also in research on TS than previously adopted.

  • Hypothyroidism is common in turner syndrome: results of a five-year follow-up.
  • 2005
  • Ingår i: The Journal of clinical endocrinology and metabolism. - : Oxford University Press. - 0021-972X .- 1945-7197. ; 90:4, s. 2131-5

    • Turner syndrome (TS) is caused by a sex chromosome aberration. The aim was to study the prevalence and incidence of thyroid disease in adults with TS. Women with TS (n = 91; mean age, 37.7 +/- 11 yr) were compared with an age-matched female random population sample (n = 228). At baseline, 15 (16%) TS women were treated for hypothyroidism, and elevated serum TSH was found in another eight (9%). As a result, hypothyroidism was more common in women with TS (25%) than in controls (2%; P < 0.0001). Serum free T4 was lower (P = 0.02), and serum TSH was higher (P < 0.0001) in TS women than in age-matched controls. Of all TS women with hypothyroidism, 10 (43%) had an elevated thyroid peroxidase antibody titer vs. 15 (22%) of those without hypothyroidism (P < 0.05), evenly distributed between the karyotype 45,X and mosaicism. A high body mass index, but not a family history or blood lipids, was associated with hypothyroidism in TS. After the 5-yr follow-up, an additional 11 (16%) developed hypothyroidism, of whom four (36%) had elevated thyroid peroxidase. Altogether, 34 (37%) TS women had hypothyroidism after the 5-yr follow-up. Autoimmune hypothyroidism was common, with an annual incidence of 3.2% in TS. Thyroid function should be checked regularly in TS.

    • Data on the prognostic value of hypertensive response to exercise in cardiovascular disease are limited. The aim was to determine whether SBP reactions during exercise have any prognostic value in relation to the long-term risk of stroke and myocardial infarction (MI).A representative cohort of men from Gothenburg, Sweden, born in 1913, who performed a maximum exercise test at age 54 years, (n = 604), was followed-up for a maximum of 44 years with regard to stroke and MI.Among the 604 men, the mean resting and maximum SBP was 141.5 (SD 18.8) and 212.1 (SD 24.6) mmHg, respectively. For maximum SBP, the risk of stroke increased by 34% (hazard ratio 1.34, 95% confidence interval 1.11-1.61) per 1-SD increase, while no risk increase was observed for MI. The highest risk of stroke among blood pressure groups was observed among men with a resting SBP of at least 140 mmHg and a maximum SBP of at least 210 mmHg with an hazard ratio of 2.09 (95% confidence interval 1.29-3.40), compared with men with a resting SBP of less than 140 mmHg and a maximum SBP of less than 210 mmHg, independent of smoking, blood glucose, cholesterol and BMI.Among middle-aged men with high resting and maximum blood pressure during maximum exercise workload, an increased risk of stroke was observed but not for MI. Further studies with larger sample sizes are needed to investigate the underlying mechanisms of the increased risk of stroke among individuals with hypertensive response to exercise.

  • Body temperature in acute myocardial infarction and its relation to early intervention with metoprolol.
  • 1988
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 20:1, s. 65-71
  • Tidskriftsartikel (refereegranskat)abstract
    • In a subsample of 223 patients participating in a double-blind trial with metoprolol in suspected acute myocardial infarction, body temperature during the first 5 days in hospital was recorded. Patients developing infarction had a mean temperature of 37.3 degrees C compared with 36.8 degrees C for those with no infarction (P less than 0.001). A positive association was observed between enzyme-estimated infarct size and body temperature (P less than 0.001). Patients given metoprolol had a mean temperature of 37.0 degrees C as compared with 37.2 degrees C in those given placebo (P = 0.03). The most marked difference between metoprolol and placebo was observed among those treated very early. We conclude that early treatment with metoprolol in suspected acute myocardial infarction appears to lower body temperature during the following days. This might reflect limitation of the infarct size.

  • Calcaneal ultrasound measurements are determined by age and physical activity. Studies in two Swedish random population samples.
  • 2000
  • Ingår i: Journal of internal medicine. - 0954-6820. ; 247:2, s. 269-78
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To present reference values and correlations with body composition, blood variables and lifestyle factors. SUBJECTS: Two random population samples from Göteborg, Sweden, one comprising 184 men and 455 women aged 25-64 years (MONICA) and the other 860 women aged 55-82 years (BEDA) were studied. METHODS: Calcaneal ultrasound measurement (LUNAR Achilles) and bioimpedance were measured. Smoking habits, coffee consumption, physical activity, psychological stress, education and marital status, as well as blood lipids, blood pressure, and fractures were studied. RESULTS: Broadband ultrasound attenuation and stiffness were higher in men than in women (P < 0. 001), but speed of sound did not differ between sexes. Speed of sound, broadband ultrasound attenuation and stiffness decreased with age (P < 0.001). In both sexes speed of sound, broadband ultrasound attenuation and stiffness correlated positively to body size variables, and negatively with smoking in women after adjustment for age. Speed of sound, broadband ultrasound attenuation and stiffness were positively related to physical activity in both sexes, and these relationships were the only ones that remained in multivariate analyses in addition to age (negative). Osteoporotic fractures increased with age. Speed of sound, broadband ultrasound attenuation and stiffness were lower amongst women with osteoporotic fractures. CONCLUSION: Speed of sound, broadband ultrasound attenuation and stiffness decreased with age and increased with physical activity, but body weight and height were not correlated in multivariate analyses. Osteoporotic fractures increased with age and were associated with lower calcaneal ultrasound values.

    • Turner syndrome (TS) is caused by an X chromosome aberration and is characterized by endogenous estrogen deficiency secondary to ovarian dysgenesis and short stature. Our aim was to study the prevalence of cardiovascular malformations and cardiovascular risk factors (blood pressure, blood lipids and glucose, coagulation factors, social factors, smoking habits) in adults with Turner syndrome in comparison with a female random population sample. One hundred women with Turner syndrome (aged 16-71 yr) underwent physical examination, echocardiography, electrocardiography, and blood sampling. Seventy-one of them were matched for age [mean age, 33.7 +/- 11 yr (range, 25-64)] with a random population sample (n = 213) of women [mean age, 34.8 +/- 9 yr (range, 25-64)] from the World Health Organization's Monitoring of Trends and Determinants in Cardiovascular Diseases Project, Göteborg. Six percent of Turner syndrome women were smokers compared with 25% in the population (P < 0.001). Turner syndrome women were relatively heavier and had a lower degree of leisure time physical activity than controls (P < 0.001). Diabetes and treatment for hypertension were present in 3 and 22% among Turner syndrome women vs. 2% (not significant) and 3% (P < 0.001) in controls, respectively. Cardiovascular malformations were found among 17% in Turner syndrome women (45,X dominated) vs. 0.5% in controls (P < 0.001). Systolic but not diastolic blood pressure was higher in Turner syndrome women. No differences were seen in serum total cholesterol, high- or low-density lipoprotein cholesterol, triglycerides, lipoprotein (a), or plasma fibrinogen concentrations between patients and controls. Diabetes or hypertension was not related to karyotype. In conclusion, congenital cardiovascular malformations were frequent. Most cardiovascular risk factors (glucose and lipid levels, fibrinogen, smoking habits) were not increased, but hypertension was more common in Turner syndrome women.

  • Insulin-like growth factor I levels in healthy adults.
  • 2004
  • Ingår i: Hormone research. - 0301-0163. ; 62 Suppl 1, s. 8-16
  • Tidskriftsartikel (refereegranskat)abstract
    • Insulin-like growth factor I (IGF-I) levels mainly reflect secretion of growth hormone (GH) in the body. The aims of this study were to compare different IGF-I assay methods in healthy individuals, test the reliability of the methods and discuss the utility of IGF-I measurement in adults. The Nichols Institute Diagnostics radioimmunoassay was used to evaluate IGF-I in two random population samples of men and women (aged 25-64 years, n = 392) taken 10 years apart, in 1985 and 1995. This method for IGF-I testing was also compared with an immunoradiometric assay (IRMA) method in 387 men and women participating in the World Health Organization MONICA (MONItoring of trends and determinants for CArdiovascular diseases) Project, Goteborg, Sweden, in 1995. Serum IGF-I decreased with increasing age in both men and women. IGF-I was higher in young women compared with young men in both cohorts, while the opposite was found in the highest age group. Age-adjusted significant correlations were found between IGF-I and smoking, fibrinogen, coffee consumption, lipoprotein (a), osteocalcin and IGF-binding protein 3. The two cohorts showed similar mean IGF-I concentrations irrespective of method. The correlation between the Nichols and the IRMA methods was high: r = 0.93 (p < 0.0001). Based on this and previous studies, population-based IGF-I measurements are robust irrespective of which commercially available method of assay is used. IGF-I levels can be used in diagnosing acromegaly as well as providing target values. IGF-I assay can be used as a complement to stimulation testing in the diagnosis of GH deficiency, and as a tool for GH dose titration.

  • Optimising health care within given budgets: Primary prevention of cardiovascular disease in different regions of Sweden
  • 2006
  • Ingår i: HEALTH POLICY. - Clare : Elsevier. - 0168-8510 .- 1872-6054. ; 75:2, s. 214-229
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the consequences of applying strict health maximisation to the choice between three different interventions with a defined budget. We analysed three interventions of preventing cardiovascular diseases, through doctor's advice on smoking secession, through blood-pressure-lowering drugs, and through lipid-lowering drugs. A state transition model has been used to estimate the cost–utility ratios for entire population in three different county councils in Sweden, where the populations were stratified into mutually excluding risk groups. The incremental cost–utility ratios are being presented in a league table and combined with the local resources and the local epidemiological data as a proxy for need for treatment. All interventions with an incremental cost–utility ratio exceeding the threshold ratios are excluded from being funded. The threshold varied between 1687 Euro and 6192 Euro. The general reallocation of resources between the three interventions was a 60% reduction of blood-pressure-lowering drugs with redistribution of resources to advice on smoking secession and to lipid-lowering drugs. One advantage of this method is that the results are very concrete. Recommendations can thereby be more precise which hopefully will create a public debate between decision-makers, practising physicians and patient groups.
