- OBJECTIVE: Our objective was to characterize the pharmacokinetics of melagatran, the active form of the oral direct thrombin inhibitor ximelagatran, and the relationship between melagatran exposure and clinical outcome in patients with acute deep vein thrombosis. METHODS: A population pharmacokinetic analysis was performed on samples from patients with deep vein thrombosis participating in a randomized dose-finding study (THRombin Inhibitor in Venous thrombo-Embolism [THRIVE I]). Patients received fixed doses of oral ximelagatran (24, 36, 48, or 60 mg twice daily) for 12 to 16 days. Thrombus size was evaluated by venography before and after treatment. Exposure-response curves were characterized for the probability of regression, no change, and progression of the thrombus extension and of having a bleeding-related event, by use of logistic regression models. RESULTS: The pharmacokinetics of melagatran (1836 samples in 264 patients) was predictable, without significant time or dose dependencies. Clearance after oral administration (population mean, 27.3 L/h) was correlated with creatinine clearance (P < 10(-6)), and volume of distribution (population mean, 176 L) was correlated with body weight (P = 2 x 10(-5)). Gender, age, or smoking did not significantly influence melagatran pharmacokinetics after the influence of renal function and body weight was accounted for. Unexplained interpatient variability values in total plasma clearance and bioavailability were 19% and 21%, respectively. The median area under the plasma melagatran concentration versus time curve across all patients and dose levels was 3.22 h x micromol/L (5th-95th percentiles, 1.35-7.69). There was no significant relationship between area under the plasma concentration versus time curve and change in thrombus extension (P = .59) or bleeding-related events (P = .77), and the estimated exposure-response curves were relatively flat. CONCLUSIONS: The pharmacokinetics of melagatran in patients with acute deep vein thrombosis was predictable after oral ximelagatran administration. Shallow exposure-response curves for efficacy and bleeding indicate that there is no need for individualized dosing or therapeutic drug monitoring in the patient population studied.

- AIM: To compare irritable bowel syndrome (IBS) patients with apparently healthy persons and to evaluate body awareness therapy, which is a physiotherapeutic remedy focusing on normalising tensions in the body, for the treatment of IBS with the hypothesis that altered body tension is associated with the syndrome. METHODS: Twenty-one IBS patients received body awareness therapy two hours weekly for 24 wk. At baseline as well as after 12 and 24 wk, they underwent examinations including resource oriented body examination in combination with body awareness scale evaluation and filled in gastrointestinal and psychological symptom questionnaires. Saliva cortisol was analysed. A group of 21 apparently healthy persons underwent the same examinations once. RESULTS: Compared to the apparently healthy group, IBS patients scored higher at baseline for gastrointestinal and psychological symptoms. They showed more often alterations in normal body tension patterns, as well as deviating cortisol slopes in saliva. After 24 wk of body awareness therapy, their gastrointestinal and psychological symptoms were reduced overall. Somatic symptoms decreased in parallel with depressive symptoms. Whole body pain score decreased, coping ability as well as biochemical stress markers improved. CONCLUSION: IBS patients scored higher for gastrointestinal and psychological symptoms, and presented with altered biochemical stress markers. Their body tension deviated compared to healthy controls. Furthermore, body awareness therapy gave relief of both somatic complaints, psychological symptoms and normalised body tension. These findings indicate that distorted tension constitutes an important part of the symptoms in IBS.

- AIM: To elucidate the differences in somatic, psychological and biochemical pattern between the subtypes of irritable bowel syndrome (IBS). METHODS: Eighty IBS patients, 30 diarrhoea predominant (D-IBS), 16 constipation predominant (C-IBS) and 34 alternating IBS (A-IBS) underwent physiotherapeutic examinations for dysfunctions in body movements and awareness and were compared to an apparently healthy control group (AHC). All groups answered questionnaires for gastrointestinal and psychological symptoms. Biochemical variables were analysed in blood. RESULTS: The D-IBS group showed less body awareness, less psychological symptoms, a more normal sense of coherence and psychosocial rating as well as higher C-peptide values. C-IBS had a higher degree of body dysfunction and psychological symptoms, as well as the lowest sense of coherence compared to controls and D-IBS. They also demonstrated the most elevated prolactin levels. A-IBS had the lowest degree of body disturbance, deteriorated quality of life and affected biochemical pattern. All subtypes had higher pain scores compared to controls. In addition they all had significantly increased triglycerides and elevated morning cortisol levels, however, without statistical significance compared with the controls. CONCLUSION: IBS subtypes showed different profiles in body awareness, somatic and psychological symptoms and in biochemical variables. D-IBS differed compared to the other groups by lowered body awareness, less psychological symptoms and a higher sense of coherence and elevated C-peptide values. C-IBS and A-IBS subtypes suffered more from depression and anxiety, associated with a lower quality of life. These differences may be important and will be taken into account in our treatment of these patients.

Utility of the amino-terminal fragment of pro-brain natriuretic peptide in plasma for the evaluation of cardiac dysfunction in elderly patients in primary health care

Tidskriftsartikel (refereegranskat)abstract
- Background: The aims of this study were to measure the N-terminal fragment of pro-brain natriuretic peptide (proBNP) in plasma in medical conditions commonly found in primary care and to evaluate the utility of these measurements in identifying impaired cardiac function in elderly patients with symptoms associated with heart failure.Methods: We studied 415 patients (221 men and 194 women; mean age, 72 years) who had contacted a primary healthcare center for dyspnea, fatigue, and/or peripheral edema. One cardiologist evaluated the patients in terms of history, physical examination, functional capacity, electrocardiography, and suspicion of heart failure. Plasma N-terminal proBNP was measured by an in-house RIA. An ejection fraction ≤40% by Doppler echocardiography was regarded as reduced cardiac function. Abnormal diastolic function was defined as an abnormal mitral inflow defined as reduced ratio of peak early diastolic filling velocity to peak filling velocity at atrial contraction (E/A ratio), or as abnormal pulmonary venous flow pattern.Results: Patients with impaired functional capacity, impaired systolic function, and/or impaired renal function had significantly increased N-terminal proBNP concentrations. By multiple regression analysis, N-terminal proBNP concentrations were also influenced by ischemic heart disease, cardiac enlargement, and certain medications but not by increased creatinine. No gender differences were observed. Patients with isolated diastolic dysfunction attributable to relaxation abnormali-ties had lower concentrations than those with normal cardiac function, whereas those with pseudonormal E/A ratios or restrictive filling patterns had higher concentrations.Conclusions: Plasma N-terminal proBNP concentrations increase as a result of impaired systolic function, age, impaired renal function, cardiac ischemia and enlargement, and certain medications. Values are high in diastolic dysfunction with pseudonormal patterns, but not in patients with relaxation abnormalities. An increase in plasma N-terminal proBNP might be an earlier sign of abnormal cardiac function than abnormalities identified by currently used echocardiographic measurements.

Tidskriftsartikel (refereegranskat)abstract
- Objective :To study age and sex specific prevalence of 30 symptoms in random samples from the general population and to analyze possible secular trends across time. Study population: The study was based on data from eight on-going Swedish cohort studies, with baseline investigations performed between 1973 and 2003. Samples were drawn from the general population of the cities of Gothenburg and Eskilstuna, and of Uppsala County. Overall, 20,160 subjects were sampled, 14,470 (71.8%) responded, of whom 12.000 were unique subjects, and 2548 were part of more than one sample. Methods: The Complaint score sub-scale of the Gothenburg Quality of Life instrument, listing 30 general symptoms was used. Responders were asked to indicate which symptoms they had experienced during the last three months. Results: Women reported on average 7.8 symptoms, and men 5.3 (p<0.0001). Women reported higher prevalence than men for 24 of the 30 symptoms. In multivariate analyses four patterns of prevalence across age were identified in both men and women; increasing prevalence, decreasing, stable and biphasic prevalence. The symptoms in the various pattern groups differed somewhat between men and women. However, symptoms related to strain were prominent among symptoms decreasing with age. Moreover, there were secular trends. Across all symptoms reporting prevalence increased over time in men (p<0.001) as well as in women (p<0.0001). Conclusions: Women reported higher total symptom prevalence than men. Symptoms related to health generally increased with age, while symptoms related to stress decreased markedly. Significant secular trends across time regarding symptom prevalence were found. © 2019 Bardel et al.

The Emerging Risk Factors Collaboration: analysis of individual data on lipid, inflammatory and other markers in over 1.1 million participants in 104 prospective studies of cardiovascular diseases
- 2007
-
Ingår i: Eur J Epidemiol. - 0393-2990. ; 22:12, s. 839-69
-
Tidskriftsartikel (refereegranskat)abstract
- Many long-term prospective studies have reported on associations of cardiovascular diseases with circulating lipid markers and/or inflammatory markers. Studies have not, however, generally been designed to provide reliable estimates under different circumstances and to correct for within-person variability. The Emerging Risk Factors Collaboration has established a central database on over 1.1 million participants from 104 prospective population-based studies, in which subsets have information on lipid and inflammatory markers, other characteristics, as well as major cardiovascular morbidity and cause-specific mortality. Information on repeat measurements on relevant characteristics has been collected in approximately 340,000 participants to enable estimation of and correction for within-person variability. Re-analysis of individual data will yield up to approximately 69,000 incident fatal or nonfatal first ever major cardiovascular outcomes recorded during about 11.7 million person years at risk. The primary analyses will involve age-specific regression models in people without known baseline cardiovascular disease in relation to fatal or nonfatal first ever coronary heart disease outcomes. This initiative will characterize more precisely and in greater detail than has previously been possible the shape and strength of the age- and sex-specific associations of several lipid and inflammatory markers with incident coronary heart disease outcomes (and, secondarily, with other incident cardiovascular outcomes) under a wide range of circumstances. It will, therefore, help to determine to what extent such associations are independent from possible confounding factors and to what extent such markers (separately and in combination) provide incremental predictive value.

Prognostic factors for recurrence of venous thromboembolism (VTE) or bleeding during long-term secondary prevention of VTE with ximelagatran
- 2005
-
Ingår i: Thromb Haemost. - 0340-6245. ; 94:3, s. 522-7
-
Tidskriftsartikel (refereegranskat)abstract
- The oral direct thrombin inhibitor ximelagatran (24 mg twice daily) has been shown to significantly reduce the incidence of recurrent venous thromboembolism (VTE) vs. placebo over 18 months, with no significant influence on bleeding (THRIVE III). The influence of potential prognostic factors on the risk of recurrent VTE or major and/or minor bleeding and their impact on ximelagatran treatment was evaluated in the THRIVE III study population. The effect of sex, age, body weight, renal function, malignancy, type of initial VTE event, and history of previous VTE events was investigated in the intention-to-treat population using Cox proportionate hazard modelling. Ximelagatran was administered to 612 patients and placebo to 611 patients. Within the placebo group, risk of recurrent VTE was higher among men than women (hazard ratio [HR]: 2.50,95% confidence interval [CI] 1.49,4.17), and in patients with one or more than one previous VTE event (HR: 1.73,95% CI 1.00, 2.99). There was a higher risk of bleeding among women than men in both the ximelagatran (HR: 1.49, 95% CI 1.06, 2.09) and placebo (HR: 1.48, 95% CI 1.01, 2.15) groups, and in placebo-treated patients with an initial pulmonary embolism (HR: 1.53, 95% CI 1.06,2.23) compared to those with initial deep vein thrombosis. There were no significant interactions between treatment effect and any of the potential prognostic factors. In conclusion, the superior efficacy of ximelagatran vs. placebo was maintained in all subgroups. Long-term use of oral ximelagatran, without coagulation monitoring or dose adjustment, should be feasible and well tolerated in a wide cross-section of patients for the secondary prevention of VTE.

Treatment of venous thromboembolism and long-term prevention of recurrence: present treatment options and ximelagatran
- 2004
-
Ingår i: Drugs. - 0012-6667. ; 64 Suppl 1, s. 37-46
-
Tidskriftsartikel (refereegranskat)abstract
- Despite the effectiveness of anticoagulant therapy for the treatment of acute venous thromboembolism and the prevention of recurrent venous thromboembolism, existing antithrombotic therapies are suboptimal. Unfractionated heparin, low-molecular-weight heparin (LMWH) and warfarin have practical limitations and carry the risk of treatment-related adverse events that restrict their clinical benefits and reduce cost-effectiveness. Efforts to achieve optimal venous thromboembolism prophylaxis by modifying the intensity of oral warfarin treatment have produced equivocal results, and there is a need for new, efficacious antithrombotic drugs providing predictable, well-tolerated oral dosing without the need for coagulation monitoring. Such agents would ideally have no significant food or drug interactions, and be suitable for both short- and long-term treatment. Ximelagatran, the first oral direct thrombin inhibitor, has the potential to fulfill many of the unmet needs in the management of venous thromboembolism.

- One difficulty in performing meta-analyses of observational cohort studies is that the availability of confounders may vary between cohorts, so that some cohorts provide fully adjusted analyses while others only provide partially adjusted analyses. Commonly, analyses of the association between an exposure and disease either are restricted to cohorts with full confounder information, or use all cohorts but do not fully adjust for confounding. We propose using a bivariate random-effects meta-analysis model to use information from all available cohorts while still adjusting for all the potential confounders. Our method uses both the fully adjusted and the partially adjusted estimated effects in the cohorts with full confounder information, together with an estimate of their within-cohort correlation. The method is applied to estimate the association between fibrinogen level and coronary heart disease incidence using data from 154,012 participants in 31 cohorts

Ximelagatran vs low-molecular-weight heparin and warfarin for the treatment of deep vein thrombosis: a randomized trial
- 2005
-
Ingår i: Jama. - 1538-3598. ; 293:6, s. 681-9
-
Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: Ximelagatran, an oral direct thrombin inhibitor with a rapid onset of action and predictable antithrombotic effect, has the potential to be a simple therapeutic alternative to current standard treatment of acute venous thromboembolism. OBJECTIVE: To compare the efficacy and safety of ximelagatran with standard enoxaparin/warfarin treatment for the prevention of recurrent venous thromboembolism. DESIGN, SETTING, AND PATIENTS: Randomized, double-blind, noninferiority trial (Thrombin Inhibitor in Venous Thromboembolism [THRIVE] Treatment Study) of 2489 patients with acute deep vein thrombosis, of whom approximately one third had concomitant pulmonary embolism. The study was conducted at 279 centers in 28 countries from September 2000 through December 2002. INTERVENTIONS: Patients were randomized to receive 6 months of treatment with either oral ximelagatran, 36 mg twice daily, or subcutaneous enoxaparin, 1 mg/kg twice daily, for 5 to 20 days followed by warfarin adjusted to maintain an international normalized ratio of 2.0 to 3.0. MAIN OUTCOME MEASURES: Recurrent venous thromboembolism, bleeding, and mortality. RESULTS: Venous thromboembolism recurred in 26 of the 1240 patients assigned to receive ximelagatran (estimated cumulative risk, 2.1%) and in 24 of the 1249 patients assigned to receive enoxaparin/warfarin (2.0%). The absolute difference between ximelagatran and enoxaparin/warfarin was 0.2% (95% confidence interval [CI], -1.0% to 1.3%). This met the prespecified criterion for noninferiority. Corresponding values for major bleeding were 1.3% and 2.2% (difference, -1.0%; 95% CI, -2.1% to 0.1%), and for mortality were 2.3% and 3.4% (difference, -1.1%; 95% CI, -2.4% to 0.2%). Alanine aminotransferase levels increased to more than 3 times the upper limit of normal in 119 patients (9.6%) and 25 patients (2.0%) receiving ximelagatran and enoxaparin/warfarin, respectively. Increased enzyme levels were mainly asymptomatic. Retrospective analysis of locally reported adverse events showed a higher rate of serious coronary events with ximelagatran (10/1240 patients) compared with enoxaparin/warfarin (1/1249 patients). CONCLUSIONS: Oral ximelagatran administered in a fixed dose without coagulation monitoring, was as effective as enoxaparin/warfarin for treatment of deep vein thrombosis with or without pulmonary embolism and showed similar, low rates of bleeding. Increased levels of liver enzymes in 9.6% of ximelagatran-treated patients require regular monitoring; the mechanism requires further evaluation. Prospective assessment of coronary events in future studies is warranted.

Tidskriftsartikel (refereegranskat)abstract
- Simple global self-ratings of health (SRH) have become increasingly used in national and international public health monitoring, and in recent decades recommended as a standard part of health surveys. Monitoring developments in population health requires identification and use of health measures, valid in relation to targets for population health. The aim of the present study was to investigate associations between SRH and sick leave, disability pension, hospital admissions, and mortality, adjusted for effects of significant covariates, in a large population-based cohort. The analyses were based on screening data from eight population-based cohorts in southern and central Sweden, and on official register data regarding sick-leave, disability pension, hospital admissions, and death, with little or no data loss. Sampling was performed 1973-2003. The study population consisted of 11,880 women and men, age 25-99 years, providing 14,470 observations. Information on SRH, socio-demographic data, lifestyle variables and somatic and psychological symptoms were obtained from questionnaires. There was a significant negative association between SRH and sick leave (Beta -13.2, p<0.0001, and -9.5, p<0.01, in women and men, respectively), disability pension (Hazard ratio 0.77, p<0.0001 and 0.76, p<0.0001, in women and men, respectively), and mortality, adjusted for covariates. SRH was also significantly associated with hospital admissions in men (Hazard ratio 0.87, p<0.0001), but not in women (Hazard ratio 0.96, p0.20). Associations between SRH on the one hand, and sick leave, disability pension, hospital admission, and mortality, on the other, were robust during the follow-up period. SRH had strong predictive validity in relation to use of social insurance facilities and health care services, and to mortality. Associations were strong and robust during follow-up.

- The ethyl analogues of mesityleopper and mesitylsilver, 2,4,6-triethylphenylcopper and 2,4,6-triethylphenylsilver, have been prepared and characterised by means of crystal structure determination. Three different compounds, [Cu-4(Et3Ph)(4)] center dot 2C(6)H(5)CH(3) (1), [Cu-4(Et3Ph)(4)]center dot 1/2(C2H5)(2)O (2) and [Ag-4(Et3Ph)(4)] center dot 1/2C(6)H(5)CH(3) (3), have thus been obtained by crystallisation from toluene or diethylether/tetrahydrofuran. All three show the square-planar metal core, most characteristic of homoleptic copper and silver aryls. The ordered (1) or disordered (2 and 3) solvent molecules are situated in the channels formed between the organometallic complexes, there being no strong directional interactions between the solvent and 2,4,6-triethylphenyleopper or 2,4,6-triethylphenylsilver.

- Aim This study aimed to estimate the prevalence, incidence rate, and lifetime risk of developing atrial fibrillation (AF) in a population-based study of Swedish men. Methods and results The study is a part of 'The Study of Men Born in 1913', which is a longitudinal prospective cohort study of 855 men born in 1913 and living in the city of Gothenburg in Sweden. They were followed from the age of 50 years until 98 years with repeated examinations and data from the Swedish National Hospital Discharge Register. A total of 185 (21.6%) men developed AF. The prevalence of AF increased from 0.4% at 50 years old, to 1.9% by 60 years old, to 4.6% by 70 years old, to 12.5% by 80 years old, and to 15.7% by 90 years old. The lifetime risk of developing AF was 22.5%. Conclusion Atrial fibrillation is rare at the age of 50 in Swedish men, but it increases exponentially with age, markedly accelerating after 70 years old. In nonagenarians, one of five men has or has had AF.

- AIM: To assess the lifetime cumulative incidence of portal venous thrombosis (PVT) in the general population. METHODS: Between 1970 and 1982, 23,796 autopsies, representing 84% of all in-hospital deaths in the Malmo city population, were performed, using a standardised protocol including examination of the portal vein. PVT patients were characterised and the PVT prevalence at autopsy, an expression of life-time cumulative incidence, assessed in high-risk disease categories and expressed in terms of odds ratios and 95% CI. RESULTS: The population prevalence of PVT was 1.0%. Of the 254 patients with PVT 28% had cirrhosis, 23% primary and 44% secondary hepatobiliary malignancy, 10% major abdominal infectious or inflammatory disease and 3% had a myeloproliferative disorder. Patients with both cirrhosis and hepatic carcinoma had the highest PVT risk, OR 17.1 (95% CI 11.1-26.4). In 14% no cause was found; only a minority of them had developed portal-hypertension-related complications. CONCLUSION: In this population-based study, PVT was found to be more common than indicated by previous clinical series. The markedly excess risk in cirrhosis and hepatic carcinoma should warrant an increased awareness in these patients for whom prospective studies of directed intervention might be considered.

- AIMS: While right intracardiac thrombosis (IT) is a potential cause of pulmonary embolism (PE) similar to that of stroke in left-sided IT, its prevalence and prognostic significance has not been studied in the general population. The aim of this study was to assess the age- and gender-specific prevalence of IT and its relation to PE in a population-based autopsy cohort. METHODS AND RESULTS: Between 1970 and 1982, 23 796 autopsies, representing 84% of all in-hospital deaths in the Malmo city population, were performed, using a standardized procedure. The relationship between IT and PE was evaluated by cohort analyses and nested case-control studies. IT was present in 1706 (7.2%) patients, 727 and 747 of whom had right and left atrial IT, respectively. PE prevalence in patients with isolated left IT, isolated right IT, and combined IT was 28.5, 35.6, and 48.9%, with RR (95% CI) of 1.5 (1.3-1.8), 2.0 (1.6-2.5), and 3.5 (2.7-4.7), respectively, compared with age- and gender-matched controls. Patients dying from ischaemic heart disease had a 3.2 (2.7-3.6) times higher risk of right IT, which was associated with 43% PE prevalence. Of all patients with PE at autopsy, right IT was found in 354 (6.5%), and the only detected source of PE in 220 (4.0%). CONCLUSION: Right cardiac thrombosis, though difficult to assess clinically, is as common as left cardiac thrombosis and is associated with an increased risk of PE. The diagnosis should be considered in all cases of PE, especially in patients with atrial fibrillation or myocardial infarction and in the absence of confirmed deep vein thrombosis.

- OBJECTIVE: Although deep vein thrombosis (DVT) and pulmonary embolism (PE) are manifestations of the same disease, far from all patients develop PE. Our objective was to investigate risk-modifying factors. SETTING, SUBJECTS AND DESIGN: Between 1970 and 1982, 23,796 autopsies, representing 84% of all in-hospital deaths in the Malmo City population, were performed, using a standardized procedure. In a case-control study nested in a population-based cohort of patients with proximal DVT, the relationship between PE and body mass index (BMI), thoracic and abdominal subcutaneous (SC) fat thickness was evaluated. RESULTS: Proximal DVT was found in 15%, of which 58% were women. Mean age in men was 4.5 years lower than in women (P<0.001). Fifty per cent of the patients had PE, half of which were fatal. Similar age- and gender distribution was found in cases and controls. Patients in the upper tertile of BMI, abdominal and thoracic SC fat thickness had, in comparison with mid-tertile, and independent of age, gender and death from cancer disease, an increased odds (95% CI) for PE of 1.24 (1.04-1.47) (P=0.014), 1.28 (1.07-1.53) (P=0.006) and 1.35 (1.13-1.61) (P=0.001), respectively, whereas in patients of the lower tertiles, a negative association was found. CONCLUSIONS: We found no differences in age- and gender distribution between PE cases and controls. BMI and SC fat thickness were markers of disease progression from proximal DVT to PE. The highly significant and independent association indicates that SC obesity may be of greater importance in venous thromboembolism as compared with cardiovascular diseases related to visceral (abdominal) obesity with lipid- and glucose metabolic disturbances.

- Despite numerous studies documenting the association between cancer and venous thromboembolism (VTE), the reason for the excessive risk in certain cancers remains obscure. No large-scale studies have yet investigated the independent effects of cancer type, site and growth pattern. Between 1970 and 1982, 23,796 standardised autopsies were performed, representing 84% of all in-hospital deaths in an urban Swedish population. The relationship between cancer and PE was evaluated with logistic regression. The overall PE prevalence was 23%, and 10% of the population had a fatal PE. Forty-two per cent of pancreatic cancer patients had PE (OR 2.55; 95% CI 2.10-3.09) (p<0.001); gall bladder, gastric, colorectal and pulmonary adenocarcinomas were similarly independently associated with PE. In comparison with squamous cell lung cancer, patients with pulmonary adenocarcinoma had 1.65 times higher odds for PE (95% CI 1.20-2.29). Adenocarcinoma and metastatic cancer were independently associated with PE risk (OR 1.27; 95% CI 1.16-1.40; p<0.001, and OR 1.10;95% CI 1.01-1.20; p=0.024, respectively) but when controlling for cancer type and spread, pancreatic cancer was still associated with an OR of 2.10 (95% CI 1.71-2.58) of PE (p<0.001). We conclude that the risk of PE in cancer patients depends not only on the cancer site and spread but also on the histological type. The excess independent risk in pancreatic cancer is intriguing and should warrant further research.

- OBJECTIVE: To study trends over 40 years in cardiovascular risk factors in normal weight, overweight and obese men, all aged 50 when examined. Design. Cross-sectional studies of five successive cohorts of men aged 50. SETTING: City of Göteborg, Sweden. SUBJECTS: Random population samples of altogether 3251 urban Swedish men born in 1913, 1923, 1933, 1943 and 1953. MAIN OUTCOME MEASURES: Anthropometry, cardiovascular risk factors, rates of nonsmoking, normotension and serum cholesterol <5 mmol L(-1) over four decades. RESULTS: Over 40 years, there was a net increase in body mass index (BMI) from 24.8 (SD = 3.2) to 26.4 (3.7) kg m(-2) (P < 0.0001), with an increase in the prevalence of obesity (BMI >or= 30 kg m(-2)) from 6.0% in 1963 to 13.8% in 2003. Favourable trends with respect to smoking, blood pressure and serum cholesterol were observed similarly amongst normal weight, overweight and obese men. In 1963, 24% of obese men were normotensive compared to 45% in 2003, and 6% had serum cholesterol <5 mmol L(-1) compared to 34% in 2003. Compared with obese men in 1963, men who were obese in 2003 had an odds ratio (OR) of 3.39 being a nonsmoker [95% confidence interval (CI): 1.56 to 7.36], 2.67 of being normotensive (1.23 to 5.83) and having serum cholesterol <5 mmol L(-1) of 8.30 (2.37 to 29.0). However, optimal risk factor status - no smoking, normotension and total serum cholesterol <5 mmol L(-1)- was still present in less than one in six men in 2003, similar across BMI categories. CONCLUSIONS: Obese Swedish men who are now in their fifties have much lower levels of other risk factors compared with obese men 40 years ago. This could contribute to explain why coronary heart disease death rates still are falling despite increasing rates of obesity.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The link between psychosocial factors and coronary heart disease is well established, but although effects on coagulation and fibrinolysis variables may be implicated, no population-based study has sought to determine whether venous thromboembolism is similarly related to psychosocial factors. OBJECTIVE: To determine whether venous thromboembolism (deep vein thrombosis or pulmonary embolism) is related to psychosocial factors. PATIENTS/METHODS: A stress questionnaire was filled in by 6958 men at baseline from 1970 to 1973, participants in a cardiovascular intervention trial. Their occupation was used to determine socio-economic status. RESULTS: After a maximum follow-up of 28.8 years, 358 cases of deep vein thrombosis and/or pulmonary embolism were identified through the Swedish hospital discharge and cause-specific death registries. In comparison with men who, at baseline, had no or moderate stress, men with persistent stress had increased risk of pulmonary embolism [hazard ratio (HR)=1.80, 95% CI: 1.21-2.67]. After multivariable adjustment, the HR decreased slightly to 1.66 (95% CI: 1.12-2.48). When compared with manual workers, men with white-collar jobs at intermediate or high level and professionals showed an inverse relationship between occupational class and pulmonary embolism (multiple-adjusted HR=0.57, 95% CI: 0.39-0.83). Deep vein thrombosis was not significantly related to either stress or occupational class. CONCLUSION: Both persistent stress and low occupational class were independently related to future pulmonary embolism. The mechanisms are unknown, but effects on coagulation and fibrinolytic factors are likely.

- OBJECTIVE: To relate lipid levels in middle-aged men to that of their fathers at 50 years of age measured 30 years earlier. DESIGN AND SUBJECTS: In 1963, 855 men born in 1913 took part in a cardiovascular risk factor survey when they were at 50 years of age. In 1993, 475 sons to these men, aged 44-56, were invited to another examination; 263 of these men were examined (response rate: 56%) and compared with their 217 fathers when they were examined at 50 years of age in 1963. In the 1993 survey, 798 men aged 50, were also examined, from a general population sample of men born in 1943 (response rate: 55%). SETTING: City of Goteborg, Sweden. MAIN OUTCOME MEASURES: Serum lipids in sons as a function of lipids in their fathers. RESULTS: Compared with the men born in 1913, both sons and men born in 1943 had lower mean serum cholesterol, but higher body mass index (BMI) and serum triglycerides. There was a significant relation between serum cholesterol in sons and their fathers (r = 0.25; P < 0.0001). Amongst sons to fathers in the highest cholesterol quartile (>6.9 mmol x L(-1)), 37% had serum cholesterol above 6.5 mmol x L(-1), compared with 16% amongst sons to fathers in the lowest quartile (<5.7 mmol x L(-1)) [adjusted odds ratio 3.73 (1.52-9.12)]. Sons to fathers with the highest serum cholesterol levels had slightly lower BMI; otherwise there was no relation between serum cholesterol in the father and any other lifestyle or biological risk factor in the sons. Serum triglyceride concentration in the father was unrelated to any variable in the son. CONCLUSIONS: There was a moderately strong association between serum cholesterol concentration in fathers and sons at middle age. However, secular trends were also important in determining serum cholesterol concentrations in those born at a later period, indicating a major role of environmental factors.
