RESUMO
Evening chronotype is known to be associated with various chronic diseases and cardiovascular risk factors. Metabolic syndrome is a group of conditions that together raise the risk of coronary heart disease, diabetes, stroke, and other serious health problems. Only a few studies have been published on the association between chronotype and metabolic syndrome in unselected population data, with conflicting results. The aim of this study was to evaluate the association between chronotype and metabolic syndrome at population level by using unselected Northern Finland Birth cohort 1966 (NFBC1966) database. The study population consists of participants with NFBC66 (n = 5,113, 57% female) at the age of 46 yr old. Chronotype was determined with shortened Morningness-Eveningness Questionnaires and expressed as morning (44%), intermediate (44%), and evening types (12%). Metabolic syndrome was determined according to the definition of International Diabetes Federation. One-way ANOVA, Kruskal-Walli's test, and χ2 tests were used to compare the chronotype groups, followed by logistic regression analysis (adjusted with alcohol consumption, smoking, marital status, level of education, and leisure-time physical activity). In women, the prevalence of metabolic syndrome was statistically significantly higher in the evening type group: 23, 24, and 34% for morning, intermediate, and evening groups, respectively (P < 0.001). In logistic regression analysis, evening chronotype was associated with higher risk of having metabolic syndrome (OR 1.5; CI 95% 1.2 to 2.0). In this population-based birth cohort study, the evening chronotype was independently associated with higher prevalence of metabolic syndrome in women.NEW & NOTEWORTHY Only a few studies have been conducted on the association between chronotype and metabolic syndrome in unselected population data, with conflicting results. In this population-based cohort study of 5,113 participants, the evening chronotype associated with metabolic syndrome in women when there was no such association in men. The result supports a previous South Korean population study of 1,620 participants, in which the association was also found in women, but not in men.

BACKGROUND: The association between rosacea and psychiatric comorbidity has been reported previously. However, there is a lack of general population studies about this subject area. OBJECTIVES: The aim of this study was to the association between rosacea with depressive and anxiety symptoms at the population level. METHODS: A clinical whole-body examination was performed by dermatologists for 1,932 subjects belonging to the Northern Finland Birth Cohort 1966 Study during the 46-year follow-up survey. The presence of depressive and anxiety symptoms was gathered by using validated Hopkins Symptom Checklist-25 (HSCL-25) included in the self-administered questionnaires. Binary logistic regression analysis was used to identify associations between rosacea and psychological symptoms. RESULTS: Rosacea was found in dermatological evaluation in 15.1% of the study subjects (n = 292). In logistic regression analyses, after adjusting for confounding factors, those with rosacea had 1.6-fold (OR 1.55, 95% CI: 1.02-2.32) risk for psychiatric symptoms according to HSCL-25 when compared with controls. In separate analyses of the HSCL-25 depression subscale, the risk was increased, especially for depressive symptoms (OR 1.56, 95% CI: 1.10-2.18). CONCLUSIONS: Patients with rosacea seem to have increased risk for depressive and anxiety symptoms in general population. Physicians treating patients with rosacea should pay more attention to the psychosocial health of patients.

Objective: To leverage large scale genetic association data to investigate the interplay between circulating cytokines and cardiometabolic traits, and thus identifying potential therapeutic targets. Design: Bi-directional Mendelian randomisation study. Setting: Genome-wide association studies from three Finnish cohorts (Northern Finland Birth Cohort 1966, Young Finns Study, or FINRISK study), and genetic association summary statistics pooled from observational studies for expression quantitative trait loci and cardiometabolic traits. Participants: Data for 47 circulating cytokines in 13 365 individuals from genome-wide association studies, summary statistic data for up to 21 735 individuals on circulating cytokines, summary statistic gene expression data across 49 tissues in 838 individuals, and summary statistic data for up to 1 320 016 individuals on cardiometabolic traits. Interventions: Relations between circulating cytokines and cardiovascular, anthropometric, lipid, or glycaemic traits (coronary artery disease, stroke, type 2 diabetes mellitus, body mass index, waist circumference, waist to hip ratio, systolic blood pressure, glycated haemoglobin, high density lipoprotein cholesterol, low density lipoprotein cholesterol, total cholesterol, triglycerides, C reactive protein, glucose, fasting insulin, and lifetime smoking). Main outcome methods: Genetic instrumental variables that are biologically plausible for the circulating cytokines were generated. The effects of cardiometabolic risk factors on concentrations of circulating cytokines, circulating cytokines on other circulating cytokines, and circulating cytokines on cardiometabolic outcomes were investigated. Results: Genetic evidence (mendelian randomisation P<0.0011) suggests that higher body mass index, waist circumference, smoking, higher concentrations of lipids, and systolic blood pressure increase circulating concentrations of several inflammatory cytokines and C reactive protein. Evidence for causal relations (mendelian randomisation P<0.0011) were noted between circulating cytokines, including a key role of vascular endothelial growth factor on influencing the concentrations of 10 other cytokines. Both mendelian randomisation (P<0.05) and colocalisation (posterior probability >0.5) suggested that coronary artery disease risk is increased by higher concentrations of circulating tumour necrosis factor related apoptosis-inducing ligand (TRAIL), interleukin-1 receptor antagonist (IL1RA), and macrophage colony-stimulating factor (MCSF). Conclusion: This study offers insight into inflammatory mediators of cardiometabolic risk factors, cytokine signalling cascades, and effects of circulating cytokines on different cardiometabolic outcomes.
RESUMO
We evaluated the survival of a subarctic population and the significance of traditional risk factors for mortality, causes of death and their seasonal variation from the period of 1984-2014. By the end of 2014 (follow-up), 644 (34.4% from 1,869) participants had died (42.1% of cardiovascular causes, 22.4% of neoplastic diseases). The average age at death±SD was 74.6±11.4 years for women (n=284) and 70.2±12.0 years for men (n=360). After adjusting for baseline age, the major risk factors predicting death were male sex (hazard ratio [HR] 1.80; 95% confidence interval [CI] 1.54-2.10), current smoking (HR 1.85; 95% CI 1.58-2.17), obesity (HR 1.75; 95% CI 1.45-2.12), high blood pressure (HR 1.46; 95% CI 1.24-1.72), cardiovascular disease (HR 1.62; 95% CI 1.36-1.93) and depression (HR 1.61; 95% CI 1.21-2.14) at baseline.The most common causes of death and the main risk factors predicting death in this population were the same as reported globally. Lifestyle factors had an important impact in predicting survival. The most common causes of death were the same for men and women. There was no significant difference in overall mortality rate between winter and summer, but cerebrovascular and pulmonary causes of death were more common during winter.

Increased blood interleukin-6 (IL-6) levels are a replicated abnormality in schizophrenia, and may be associated with smaller hippocampal volumes and greater cognitive impairment. These findings have not been investigated in a population-based birth cohort. The general population Northern Finland Birth Cohort 1966 was followed until age 43. Subjects with schizophrenia were identified through the national Finnish Care Register. Blood IL-6 levels were measured in n = 82 subjects with schizophrenia and n = 5373 controls at age 31. Additionally, 31 patients with schizophrenia and 63 healthy controls underwent brain structural MRI at age 34, and cognitive testing at ages 34 and 43. Patients with schizophrenia had significantly higher median (interquartile range) blood IL-6 levels than controls (5.31, 0.85-17.20, versus 2.42, 0.54-9.36, p = 0.02) after controlling for potential confounding factors. In both schizophrenia and controls, higher blood IL-6 levels were predictors of smaller hippocampal volumes, but not cognitive performance at age 34. We found evidence for increased IL-6 levels in patients with midlife schizophrenia from a population-based birth cohort, and replicated associations between IL-6 levels and hippocampal volumes. Our results complement and extend the previous findings, providing additional evidence that IL-6 may play a role in the pathophysiology of schizophrenia and associated brain alterations.

Objective: The main objective of this study was to investigate the psychometric properties of the Zung Self-Rating Depression Scale (SDS) and evaluate screening parameters capability of the SDS with the Beck Depression Inventory (BDI-21) among the elderly population. Design: A population-based study Setting: Community Subjects: 520 adults, aged 72-73 years, living in the city of Oulu, Finland. Main outcome measures: The screening parameters of the SDS questions and BDI-21 for detecting severity of depression. The Mini Neuropsychiatric Interview for diagnosing major depression. Results: The optimal cut-off point for the SDS was 39. The sensitivity and specificity parameters for this cut-off point were 79.2% (95% CI 57.8-92.9) and 72.2% (95% CI 67.9-76.1), respectively. Positive and negative predictive values were 12.5% (95% CI 7.7-18.8) and 98.6% (95% CI 96.7-99.5), respectively. Moreover, there was no statistically significant difference in diagnostic accuracy indices of the cut-off points 39 and 40. In a receiver operating characteristic analysis, the area under the curve was 0.85 (95%CI 0.77-0.92) for the SDS total score and 0.89 (95% CI 0.83-0.96) for the BDI-21 (p = 0.137). Conclusion: Using the traditional cut-off point, the SDS was convenient for identifying clinically meaningful depressive symptoms in an elderly Finnish population when compared with the BDI-21 which is one of the most commonly used depression screening scales. The sensitivity and specificity of these two screening tools are comparable. Based on our study, the SDS is convenient for identifying clinically meaningful depressive symptoms among older adults at the community level. Key points The widely used Zung Self-Rating Depression Scale (SDS) has not previously been validated among elderly people at the community level. The sensitivity and specificity of SDS (cut-off point 39) were 79.2% and 72.2%. The positive and negative predictive values for SDS were 12.5% and 98.6%. SDS is convenient for identifying major depression in an elderly population and regarding sensitivity and specificity comparable to BDI-21.

Bullous pemphigoid (BP) and dermatitis herpetiformis (DH) are autoimmune bullous skin diseases. DH has been described to evolve into BP and the two diseases can have overlapping clinical appearances and diagnostic findings, but the association between DH and BP has not previously been studied in a large population. To evaluate DH and celiac disease as risk factors for BP, we conducted a retrospective case-control study of patients with BP and matched controls with basal cell carcinoma diagnosed in Finland between 1997 and 2013. A total of 3,397 patients with BP and 12,941 controls were included in the study. Forty-one (1.2%) BP patients and 7 (0.1%) controls had preceding DH. Diagnosed DH increased the risk of BP 22-fold (odds ratio = 22.30; 95% confidence interval = 9.99-49.70) and celiac disease 2-fold (odds ratio = 2.54; 95% confidence interval = 1.64-3.92) compared to controls. Eighteen (43.9%) of the patients who had DH and subsequent BP had bought dapsone during the 2 years prior to their BP diagnosis. Mean time between diagnosed DH and BP was 3 years. We conclude that diagnosis of DH is associated with a striking increase in the risk for BP.

BACKGROUND: Dipeptidyl peptidase 4 inhibitors (DPP4is) used to treat diabetes have been reported to be associated with an increased risk of bullous pemphigoid (BP). There are no previous reports analyzing the risk of BP in patients who are using other diabetes medications. OBJECTIVE: To evaluate the association between diabetes medications other than DPP4i and development of BP. METHODS: We investigated the prevalence of diabetes among patients with BP and the association between the use of diabetes drugs (excluding DPP4i, metformin, and insulin) and BP by analyzing national Finnish registry data for 3397 patients with BP and 12,941 patients with basal cell carcinoma as controls. RESULTS: Our results show that 19.6% of patients with BP have type 2 diabetes. Use of none of the investigated medications was associated with an increased risk of BP. LIMITATIONS: Because this was a registry-based study, it was not possible to verify the accuracy of the diagnoses. The risk of BP in users of glucagon-like peptide 1 receptor agonists could not be analyzed. CONCLUSION: Our study shows that the investigated diabetes drugs are not associated with an increased risk of BP in a Finnish patient database, indicating they can be safely used in this population. Generalization of these results to other populations will require further study.

BACKGROUND: Hidradenitis suppurativa (HS) is associated with various somatic and psychiatric comorbidities. Data regarding comorbidities in young patients with HS are sparse. OBJECTIVE: We analyzed both somatic and psychiatric comorbidities in young patients in a nationwide HS cohort. METHODS: In this retrospective case-control study, data from cases of HS in young (age 5 to <18 years) patients and age-matched controls with benign melanocytic nevi were collected from the Finnish Care Register for Health Care. The prevalence of preselected comorbidities was compared between the HS and control groups. RESULTS: A total of 153 HS cases were found in the specified age group. Of these, 34.0% had at least 1 somatic comorbidity compared with 4.9% of the controls. At least 1 of the preselected psychiatric diagnoses was present before the age of 18 years in 15.7% of case patients with HS compared with in 5.6% of the controls. By the age of 23 years, 23.5% of the patients with HS and 8.7% of the controls had at least 1 identified psychiatric comorbidity. LIMITATIONS: Despite this being one of the largest HS cohorts ever studied, the number of young patients with HS was relatively low. Because this was a registry-based study, it was not possible to verify the accuracy of the International Classification of Diseases codes. CONCLUSION: Physicians should monitor young patients with HS for both somatic and psychiatric comorbidities.

Low grade inflammation is associated with many noncommunicable diseases. The association between skin diseases in general and systemic inflammation has not previously been studied at the population level. A whole-body investigation on 1,930 adults belonging to Northern Finland Birth Cohort 1966 was performed and high sensitive C-reactive protein (CRP) level was measured as a marker of low grade inflammation in order to determine the association between low grade inflammation and skin diseases in an unselected adult population. After adjustment for confounding factors the following skin disorders were associated with low grade inflammation in multinomial logistic regression analysis: atopic eczema (OR 2.2, 95% CI 1.2-3.9), onychomycosis (OR 2.0, 1.2-3.2) and rosacea (OR 1.7, 1.1-2.5). After additionally adjusting for body mass index and systemic diseases, the risks for atopic eczema (OR 2.4, 1.3-4.6) and onychomycosis (OR 1.9, 1.1-3.1) remained statistically significant. In conclusion, low grade inflammation is present in several skin diseases.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease of hair follicles that is associated with various comorbidities. To further clarify the associations between HS and psychiatric disorders, we conducted a nationwide retrospective study that included 4,381 patients with HS, and 39,554 with psoriasis and 43,248 with melanocytic nevi as controls. Patient data were obtained from the statutory Finnish Care Register for Health Care. The incidence of HS was 3.0/100,000 persons/year. At least one psychiatric diagnosis was found in 24.1% of the patients with HS compared with 19.1% of the patients with psoriasis (odds ratio 1.34; 95% confidence interval 1.24-1.46) and 13.5% of those with melanocytic nevi (odds ratio 2.04; confidence interval 1.88-2.22). Every mental disorder examined was significantly more frequent in HS than in the two other groups. Mental disorders were more common in women than in men with HS and psoriasis. The main finding of our study is that patients with HS have a higher risk of mental disorders than patients with psoriasis. Additionally, this study reveals that HS is associated with both schizophrenia (odds ratio 1.57; confidence interval 1.24-1.98) and bipolar disorder (odds ratio 1.81; confidence interval 1.47-2.23), findings that to our knowledge have not been reported previously.

OBJECTIVE: To study and compare the utilisation of primary health care services among 46-year-old current smokers, ex-smokers and never-smokers, and to estimate the corresponding costs. METHODS: This population-based cohort study is based on the Northern Finland Birth Cohort 1966, which is a longitudinal research program in Finland's two northernmost provinces. The study is based on data collected at the 46-year follow-up, during which a total of 4997 individuals completed questionnaires on their primary health care service utilisation. Primary health care covered visits to both occupational and public health care (typically community health centres). RESULTS: Current smokers visited primary health care professionals more often per year than never-smokers, regardless of gender (RR 1.24, 95 % confidence interval 1.10-1.43 for men; RR 1.10, 1.01-1.22 for women). When primary health care services were categorised based on the type of service provided, current smokers of both genders were more likely to visit a dentist (RR 1.56, 1.32-1.84 for men; RR 1.34, 1.15-1.55 for women) or a physician (RR 1.20, 1. 03-1.40 for men; RR 1.15, 1.02-1.30 for women) than their never-smoking counterparts (BMI adjusted for). For men, the total annual costs of primary health care visits were 28 % higher for current smokers versus never-smokers (P < 0.001). For women, the difference was 21 % (P < 0.01). CONCLUSIONS: Smokers visit primary health care professionals more often already at the age of 46, before the expected diagnosis of fatal smoking-related illnesses. This phenomenon not only predicts an elevated incidence of serious illnesses in later life (such as cardiovascular disease), but also causes an economic burden on the health care system.

OBJECTIVE: Meta-analyses of cross-sectional studies confirm an increase in circulating inflammatory markers during acute psychosis. Longitudinal studies are scarce but are needed to understand whether elevated inflammatory markers are a cause or consequence of illness. We report a longitudinal study of serum C-reactive protein (CRP) in adolescence and subsequent risk of schizophrenia and related psychoses in adulthood in the Northern Finland Birth Cohort 1986. METHOD: Serum high-sensitivity CRP was measured at age 15/16 years in 6362 participants. ICD-10 diagnoses of schizophrenia and related psychoses were obtained from centralised hospital inpatient and outpatient registers up to age 27 years. Logistic regression calculated odds ratios (ORs) for psychotic outcomes associated with baseline CRP levels analysed as both continuous and categorical variables using American Heart Association criteria. Age, sex, body mass index, maternal education, smoking, and alcohol use were included as potential confounders. RESULTS: By age 27years, 88 cases of non-affective psychosis (1.38%), of which 22 were schizophrenia (0.35%), were identified. Adolescent CRP was associated with subsequent schizophrenia. The adjusted OR for schizophrenia by age 27yearsfor each standard deviation (SD) increase in CRP levels at age 15/16yearswas 1.25 (95% CI, 1.07-1.46), which was consistent with a linear, dose-response relationship (P-value for quadratic term 0.23). Using CRP as a categorical variable, those with high (>3mg/L) compared with low (<1mg/L) CRP levels at baseline were more likely to develop schizophrenia; adjusted OR 4.25 (95% CI, 1.30-13.93). There was some indication that higher CRP was associated with earlier onset of schizophrenia (rs=-0.40; P=0.07). CONCLUSIONS: A longitudinal association between adolescent CRP levels and adult schizophrenia diagnosis indicates a potentially important role of inflammation in the pathogenesis of the illness, although the findings, based on a small number of cases, need to be interpreted with caution and require replication in other samples.

Having multiple melanocytic naevi (< 50 naevi) is one of the strongest risk factors for melanoma. However, the epidemiology in adults is unclear. This comprehensive dermatological status investigation of 1,932 birth-cohort study cases aged 46 years analysed the prevalence of multiple melanocytic naevi and their association with sex, socioeconomic status (education) in childhood and adulthood, skin type and sunbathing habits. The prevalence of multiple melanocytic naevi was 11.6% (223/1,930). Higher education (odds ratio (OR) 2.11, 95% confidence interval (95% CI) 1.51-2.96), male sex (OR 1.48, 95% CI 1.07-2.06), sun-sensitive skin type (OR 2.09, 95% CI 1.34-3.27) and regular use of sunscreen (OR 2.03, 95% CI 1.23-3.37) were associated with increased risk of multiple naevi. Inflammatory skin diseases decreased (OR 0.49, 95 CI% 0.33-0.72) the risk of multiple naevi. In conclusion, several risk factors were found for multiple naevi among adults living in high latitudes, in Northern Finland.

Bullous pemphigoid (BP) is an autoimmune blistering skin disease with increasing incidence. BP is associated with neurological disorders, but it has not been established, what subtypes of dementia and stroke are associated with BP, and what is the temporal relation between these diseases. Also, the association between BP and psychiatric disorders is controversial. We conducted a retrospective nationwide study, using the Finnish Care Register for Health Care diagnoses between 1987 and 2013. The study population of 4524 BP patients were compared with 66138 patients with basocellular carcinoma (BCC), neurological and psychiatric comorbid disorders were evaluated for both groups, and associations were estimated by Cox regression and logistic regression analyses. The strongest risk of developing BP was found after diagnosis of multiple sclerosis (MS) (OR=5.9, 95% CI 3.9-8.5). Among psychiatric diseases, the corresponding risk was strongest in schizophrenia (OR=2.7, 95% CI 2.0-3.5), and as a novel finding, also personality disorders (OR=2.2, 95% CI 1.3-3.3) preceded BP. In conclusion, many psychiatric disorders, especially schizophrenia, carry heightened risk for BP. Furthermore, several neurological diseases which cause central nervous system inflammation or degeneration were related to BP, and the association was strongest between MS and BP.

OBJECTIVE: To investigate how individual risk factors for cardiovascular disease (CVD) (blood pressure, lipid levels, body mass index, waist and hip circumference, use of antihypertensive or hypolipidemic medication, and diagnosed diabetes) differ in people aged 46â years with different smoking behaviour and history. METHODS: This population-based cohort study is based on longitudinal data from the Northern Finland Birth Cohort 1966 project. Data were collected at the 31-year and 46-year follow-ups, when a total of 5038 and 5974 individuals participated in clinical examinations and questionnaires. Data from both follow-ups were available for 3548 participants. In addition to individual CVD risk factors, Framingham and Systematic Coronary Risk Evaluation (SCORE) algorithms were used to assess the absolute risk of a CVD event within the next decade. RESULTS: The differences in individual risk factors for CVD reached statistical significance for some groups, but the differences were not consistent or clinically significant. There were no clinically significant differences in CVD risk as measured by Framingham or SCORE algorithms between never smokers, recent quitters and former smokers (7.5%, 7.4%, 8.1% for men; 3.3%, 3.0%, 3.2% for women; p<0.001). CONCLUSIONS: The effect of past or present smoking on individual CVD risk parameters such as blood pressure and cholesterol seems to be of clinically minor significance in people aged 46â years. In other words, smoking seems to be above all an independent risk factor for CVD in the working-age population. Quitting smoking in working age may thus reduce calculated CVD risk nearly to the same level with people who have never smoked.
RESUMO
BACKGROUND: Despite smoking cessation efforts, cigarette smoking remains a serious general and oral health problem. We aimed to investigate the putative benefits of smoking cessation on dentition and to analyse whether the time elapsed since smoking cessation associated positively with the remaining number of teeth. METHODS: This cross-sectional study analyses data from the 46-year follow-up of the Northern Finland Birth Cohort Study 1966 (NFBC1966). A total of 5 540 subjects participated in this cross-sectional study, which utilises both clinical dental examinations and mailed questionnaires. We used the following information on smoking: status (current, former, never), years of smoking (current, former) and years elapsed since smoking cessation (former). Self-reported and clinically measured number of teeth (including third molars) served as alternative outcomes. We used binary logistic regression models to analyse the dichotomised number of teeth ('0-27', '28-32') and then calculated unadjusted and adjusted odds ratios (OR) with 95 % confidence intervals (CI) for the smoking variables (never smoker as the reference). Gender, education, tooth brushing frequency, diabetes and alcohol use served as confounders for the adjusted models. RESULTS: Ten years or more of smoking associated with tooth loss; this effect was the strongest among men who reported having an ongoing smoking habit (self-reported outcome: adjusted OR = 1.74, CI = 1.40-2.16) and the weakest among women classified as former smokers (self-reported outcome: adjusted OR = 1.27, CI = 1.00-1.62). CONCLUSIONS: This study shows that smoking has long-term effects on tooth loss even after cessation. The findings support smoking cessation efforts to reduce oral health risks.

OBJECTIVE: To analyse the utilization of health care services of people who tested positive for GAD compared to those who tested negative. SETTING: A cross-sectional study from the Northern Finland 1966 Birth Cohort. SUBJECTS: A total of 10,282 members followed from birth in a longitudinal study were asked to participate in a follow-up survey at the age of 46. As part of this survey they filled in questionnaries concerning health care utilization and their illness history as well as the GAD-7 screening tool. Althogether 5,480 cohort members responded to the questionnaries. MAIN OUTCOME MEASURES: Number of visits in different health care services among people who tested positive for GAD with the GAD-7 screening tool compared to those who tested negative. RESULTS: People who tested positive for GAD had 112% more total health care visits, 74% more total physician visits, 115% more visits to health centres, 133% more health centre physician visits, 160% more visits to secondary care, and 775% more mental health care visits than those who tested negative. CONCLUSION: People with GAD symptoms utilize health care services more than other people. Key Points Generalised anxiety disorder (GAD) is a common but poorly identified mental health problem in primary care. People who tested positive for GAD utilise more health care services than those who tested negative. About 58% of people who tested positive for GAD had visited their primary care physician during the past year. Only 29% of people who tested positive for GAD had used mental health services during the past year.

Bullous pemphigoid (BP) is an autoimmune skin disease of elderly people, which is associated with increased mortality. The aim of this study was to investigate the standardized mortality ratio (SMR) for BP in Finland, and concomitant comorbidities and medications. This was a retrospective database study of all cases of BP diagnosed at the Department of Dermatology, Oulu University Hospital, Finland, between 1985 and 2012. A total of 198 immunologically confirmed cases of BP were found. One-year mortality was 16.7%, and SMR 7.56 (95% confidence interval (CI) 4.98-10.14). The most common comorbidities were cardiovascular diseases (76.3%) and neurodegenerative diseases (40.9%). Malignancies (8.6%) were associated with increased mortality (hazard ratio = 2.4, 95% CI 1.1-5.5, p = 0.047). A novel finding was that polypharmacy was very common in patients with BP, and the higher the number of drugs, the greater the mortality. In conclusion, the mortality for BP in Finland is 7.6-fold that of a reference population, and malignancies and polypharmacy are associated with increased mortality.

BACKGROUND AND AIMS: The aim of the present study was to assess soluble CD40 Ligand (sCD40L) levels in relation to impaired glucose tolerance (IGT) at population level. METHODS: This study is part of a prospective, population-based cohort study, carried out from 1990 to 2008 in northern Finland. Study members, born in 1935 and living in the City of Oulu, underwent oral glucose tolerance test (OGTT) and measurement of plasma sCD40L at three different time points during the 15-year follow-up. The total number of study members who underwent OGTT was 768 at the baseline, 557 at the first and 467 at the second follow-up. SCD40L levels in patients with IGT were compared with those in subjects with normal glucose tolerance or impaired fasting glucose (non-IGT). RESULTS: Geometric mean level of sCD40L was significantly higher in the IGT group compared with the non-IGT group at the baseline (0.42 vs. 0.27 ng/mL) and at the first follow-up (1.50 vs. 0.36 ng/mL) (repeated measures mixed models ANOVA, p < 0.05). At the second follow-up (age 72-73 years), however, the difference was not statistically significant (9.44 vs. 7.24 ng/mL). During the entire follow-up, the levels of sCD40L increased significantly both in IGT and non-IGT groups. CONCLUSION: We found that plasma sCD40L level increases with age as well as there are elevated levels of plasma sCD40L in subjects with IGT compared with non-IGT. This may indicate an increased cardiovascular risk in older age and in subjects with IGT.
