    Cerebral venous thrombosis (CVT) covers up to a third of all venous thromboses (VTs) detected in patients with acute lymphoblastic leukemia (ALL). It usually hampers patients' lives and may also endanger efficient leukemia treatment. Although many factors have been suggested to account for an elevated risk of VTs in patients with ALL, there still is a lack of studies focusing on CVTs and especially in the setting of adult ALL patients. We studied in our retrospective population-based cohort the occurrence, characteristics, as well as risk factors for VTs in 186 consecutively diagnosed Finnish adult ALL patients treated with a national pediatric-inspired treatment protocol ALL2000. In the risk factor analyses for VTs we found a distinction of the characteristics of the patients acquiring CVT from those with other kinds of VTs or without thrombosis. In contrast to previous studies we were also able to compare the effects of asparaginase in relation to CVT occurrence. Notably, more than half of the CVTs were diagnosed prior the administration of asparaginase which accentuates the role of other risk factors on the pathophysiology of CVT compared to truncal or central venous line (CVL) VTs in adult ALL patients.

    Background: Studies investigating biomechanical risk factors for knee injuries in sport-specific tasks are needed. Purpose: To investigate the association between change of direction (COD) biomechanics in a 180-degree pivot turn and knee injury risk among youth team sport players. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 258 female and male basketball and floorball players (age range, 12-21 years) participated in the baseline COD test and follow-up. Complete data were obtained from 489 player-legs. Injuries, practice, and game exposure were registered for 12 months. The COD test consisted of a quick ball pass before and after a high-speed 180-degree pivot turn on the force plates. The following variables were analyzed: peak vertical ground-reaction force (N/kg); peak trunk lateral flexion angle (degree); peak knee flexion angle (degree); peak knee valgus angle (degree); peak knee flexion moment (N.m/kg); peak knee abduction moment (N.m/kg); and peak knee internal and external rotation moments (N.m/kg). Legs were analyzed separately and the mean of 3 trials was used in the analysis. Main outcome measure was a new acute noncontact knee injury. Results: A total of 18 new noncontact knee injuries were registered (0.3 injuries/1000 hours of exposure). Female players sustained 14 knee injuries and male players 4. A higher rate of knee injuries was observed in female players compared with male players (incidence rate ratio, 6.2; 95% CI, 2.1-21.7). Of all knee injuries, 8 were anterior cruciate ligament (ACL) injuries, all in female players. Female players displayed significantly larger peak knee valgus angles compared with male players (mean for female and male players, respectively: 13.9 degrees +/- 9.4 degrees and 2.0 degrees +/- 8.5 degrees). No significant associations between biomechanical variables and knee injury risk were found. Conclusion: Female players were at increased risk of knee and ACL injury compared with male players. Female players performed the 180-degree pivot turn with significantly larger knee valgus compared with male players. However, none of the investigated variables was associated with knee injury risk in youth basketball and floorball players.

    Background: Mental disorders can affect work ability and lead to early exit from the labour market through disability pension. Aims: This study aimed to identify childhood determinants of psychiatric disability pension in early adulthood. Methods: The 1987 Finnish Birth Cohort includes a complete census of children born in a single year. The children were followed up from birth until 31 December 2012 using official registers maintained by the Finnish authorities. Risk factors for disability pension were examined in the full 1987 cohort (N = 58,739) and among children who had received mental health care (N = 9,599). Odds ratios were calculated for disability pension due to all mental disorders and separately for schizophrenia, depressive and anxiety and other mental and behavioural disorders in association with childhood determinants. Results: Altogether, 1.4% of cohort members had retired due to mental disorders in 2003-2012. In the full 1987 cohort, female sex, parental divorce and social assistance, both mother's and father's psychiatric care and mother's psychiatric disability pension increased the risk for disability pension due to mental disorders. Among children who had received mental health care, risk factors for psychiatric disability pension were father's psychiatric care and mother's psychiatric disability pension. Conclusion: Childhood determinants were related to the risk of psychiatric disability pension before the age of 25. The risk factors varied by the diagnosis of the disability pension. Using knowledge of this study's risk factors should enable the identification of adolescents and young adults in general population and especially in the mental health care population who are at greatest risk of receipt of psychiatric disability pension.

    Patients with inflammatory bowel disease (IBD) are at increased risk for developing symptomatic Clostridium difficile infection (CDI) with worse clinical outcomes, including mortality, as compared with the general population. IBD-patients are also more susceptible to have recurrences of CDI. At present, predisposing factors for CDI in IBD-patients are poorly established. To characterize IBD-related CDI, a retrospective cohort from HUS register was gathered. Patient characteristics were compared with two control groups: IBD-patients with CDI and CDI-patients. According to our results, there was no statistically significant difference in mortality rate between IBD- and CDI-patients in contrary to previous reports. We detected corticosteroid consumption in IBD patients with CDI to be greater than in patient with IBD alone. It could be considered as a risk factor for CDI. Clarifying risk factors for CDI could lead to better understanding of optimal treatment for CDI in IBD patients.

    Aims: Disparity in cardiovascular disease (CVD) mortality and risk factor levels between urban and rural regions has been confirmed worldwide. The aim of this study was to examine how living in different community types (urban-rural) in childhood and adulthood are related to cardiovascular risk factors and surrogate markers of CVD such as carotid intima-media thickness (IMT) and left ventricular mass (LVM). Methods: The study population comprised 2903 participants (54.1% female, mean age 10.5 years in 1980) of the Cardiovascular Risk in Young Finns Study who had been clinically examined in 1980 (age 3-18 years) and had participated in at least one adult follow-up (2001-2011). Results: In adulthood, urban residents had lower systolic blood pressure (-1 mmHg), LDL-cholesterol (-0.05 mmol/l), lower body mass index (-1.0 kg/m(2)) and glycosylated haemoglobin levels (-0.05 mmol/mol), and lower prevalence of metabolic syndrome (19.9 v. 23.7%) than their rural counterparts. In addition, participants continuously living in urban areas had significantly lower IMT (-0.01 mm), LVM (1.59 g/m(2.7)) and pulse wave velocity (-0.22 m/s) and higher carotid artery compliance (0.07%/10 mmHg) compared to persistently rural residents. The differences in surrogate markers of CVD were only partially attenuated when adjusted for cardiovascular risk factors. Conclusions: Participants living in urban communities had a more favourable cardiovascular risk factor profile than rural residents. Furthermore, participants continuously living in urban areas had less subclinical markers related to CVD compared with participants living in rural areas. Urban-rural differences in cardiovascular health might provide important opportunities for optimizing prevention by targeting areas of highest need.

    Background and objectives Increased donor age is one of the most important risk factors for delayed graft function (DGF), and previous studies suggest that the harmful effect of cold ischemia time is increased in kidneys from older donors. Our aim was to study the association of increased donor age and cold ischemia time with the risk of delayed graft function in a large cohort kidney transplants from the current era. Design, setting, participants, & measurements The Scientific Registry of Transplant Recipients was used for this observational, retrospective registry analysis to identify all deceased donor kidney transplantations in the United States between 2010 and September 2018, who were on dialysis pretransplantation (n=90,810). The association of donor age and cold ischemia time with the risk of DGF was analyzed in multivariable models adjusted for recipient characteristics (age, race, sex, diabetes, calculated panel-reactive antibodies, pretransplant dialysis duration) and donor characteristics (cause of death, sex, race, body mass index, creatinine, donation after circulatory death status, history of hypertension, and HLA mismatch). Results Cold ischemia time and donor age were independently associated with the risk of DGF, but the risk of DGF was not statistically significantly lower in donor age categories between 50 and 64 years, compared with donors ?65 years. The harmful association of cold ischemia time was not higher in kidneys from older donors in any age category, not even among donation after circulatory death donors. When donor risk was assessed with kidney donor profile index, although a statistically significant interaction with cold ischemia time was found, no practically meaningful increase in cold-ischemia susceptibility of kidneys with a high kidney donor profile index was found. Conclusions We were unable to demonstrate an association between donor age and DGF. The association of longer cold ischemia time with the risk of DGF was not magnified in older or more marginal donors.

    Background: Coronary heart disease mortality has been internationally high in eastern Finland. The excessive mortality risk in Eastern compared with western Finns is explained by differences in cardiometabolic risk profile. Current risk profile differences and association with migration have not been reported. We examined the association of place of residence (east west) and specifically migration with cardiometabolic risk markers and carotid intima media thickness (IMT). Methods: The study population included 2204 participants with data available from childhood/youth in 1980 and follow-up examination in 2007. Results: Participants residing in eastern Finland in adulthood had 0.022 +/- 0.004mm higher IMT than Western participants. Those who migrated east-to-west had lower IMT than those staying in the east (0.027 +/- 0.006mm, p

    Background: Hormonal contraception is commonly used worldwide, but its systemic effects across lipoprotein subclasses, fatty acids, circulating metabolites and cytokines remain poorly understood. Methods: A comprehensive molecular profile (75 metabolic measures and 37 cytokines) was measured for up to 5841 women (age range 24-49 years) from three population-based cohorts. Women using combined oral contraceptive pills (COCPs) or progestin-only contraceptives (POCs) were compared with those who did not use hormonal contraception. Metabolomics profiles were reassessed for 869 women after 6 years to uncover the metabolic effects of starting, stopping and persistently using hormonal contraception. Results: The comprehensive molecular profiling allowed multiple new findings on the metabolic associations with the use of COCPs. They were positively associated with lipoprotein subclasses, including all high-density lipoprotein (HDL) subclasses. The associations with fatty acids and amino acids were strong and variable in direction. COCP use was negatively associated with albumin and positively associated with creatinine and inflammatory markers, including glycoprotein acetyls and several growth factors and interleukins. Our findings also confirmed previous results e.g. for increased circulating triglycerides and HDL cholesterol. Starting COCPs caused similar metabolic changes to those observed cross-sectionally: the changes were maintained in consistent users and normalized in those who stopped using. In contrast, POCs were only weakly associated with metabolic and inflammatory markers. Results were consistent across all cohorts and for different COCP preparations and different types of POC delivery. Conclusions: Use of COCPs causes widespread metabolic and inflammatory effects. However, persistent use does not appear to accumulate the effects over time and the metabolic perturbations are reversed upon discontinuation. POCs have little effect on systemic metabolism and inflammation.

    Background The aim of this study was to assess the association between endothelial function and early-onset cryptogenic ischemic stroke (CIS), with subgroup analyses stratified by sex and age groups. Methods and Results We prospectively enrolled 136 consecutive patients aged 18 to 49 years (median age, 41 years; 44% women) with a recent CIS and 136 age- and sex-matched (+/- 5 years) stroke-free controls. Endothelial function was measured with an EndoPAT 2000 device and analyzed as tertiles of natural logarithm of reactive hyperemia index with lower values reflecting dysfunction. We used conditional logistic regression adjusting for age, education, hypertension, diabetes mellitus, dyslipidemia, current smoking, heavy drinking, obesity, and diet score to assess the independent association between endothelial function and CIS. Patients in the lowest tertile of natural logarithm of reactive hyperemia index were more often men and they more frequently had a history of dyslipidemia; they were also more often obese, had a lower diet score, and lower high-density lipoprotein cholesterol. In the entire cohort, we found no association in patients with endothelial function and CIS compared with stroke-free controls. In sex- and age-specific analyses, endothelial dysfunction was associated with CIS in men (adjusted odds ratio [OR], 3.50 for lowest versus highest natural logarithm of reactive hyperemia index tertile; 95% CI, 1.22-10.07) and in patients >= 41 years (OR, 5.78; 95% CI, 1.52-21.95). These associations remained significant when dyslipidemia was replaced with the ratio of total to high-density lipoprotein cholesterol. Conclusions Endothelial dysfunction appears to be an independent player in early-onset CIS in men and patients approaching middle age.

    Low level of physical activity is a risk factor for chronic non-communicable diseases. Specifically, people at risk of Type 2 Diabetes (T2D) have shown to benefit from being physically active. The objective of this study was to explore what factors were associated with low physical activity in people at high risk of T2D living in Bogota and Barranquilla, Colombia. Methodology: Cross-sectional study using baseline data from a quasi-experimental clinical trial (PREDICOL Project). The study included 1,135 participants of Bogota and Barranquilla that presented a high risk of developing T2D according to the Finnish Diabetes Risk Score (>12 points) and who underwent an oral glucose tolerance test. The main outcome variable was the level of physical activity assessed by the International Physical Activity Questionnaire. Unadjusted and adjusted logistic regression analysis were used to calculate odds ratios (OR) and the corresponding 95% confidence intervals (CI). Results: In total, 72.5% of the study participants had low level of physical activity. Participants in the age group between 45 and 54 years showed 74% greater odds of having low physical activity compared with the youngest age group (OR 1.74, 95% CI 1.1 -2.8). People living in Barranquilla were eight times more likely to have low physical activity compared with those in Bogota D.C. (OR 8.1, 95% CI 5.7 to 11.4). Conclusion: A large proportion of the population at risk of developing D2T in two large cities of Colombia have a sedentary lifestyle. Interventions should be designed and implemented in order to increase physical activity in these populations.

    This licentiate thesis consists of a literature review and a retrospective study. Diabetes mellitus is a common endocrinopathy in cats. It mainly resembles type II diabetes mellitus of humans, where the dysfunction of pancreatic beta cells together with peripheral insulin resistance causes increased blood glucose concentrations. Along with other risk factors such as breed and neuter status, obesity is closely related to the development of feline diabetes mellitus. The aim of the retrospective study was to assess risk factors and treatment protocols of diabetes mellitus. Factors influencing treatment outcome were also investigated. The results were compared with current scientific evidence. The hypotheses were that diabetic cats with an optimal body condition score (BCS) are more likely to achieve stable disease requiring administration of exogenous insulin and are more likely to achieve remission, where administration of exogenous insulin is no longer needed. The veterinary patient database ProvetNet was used to search for cats with diabetes mellitus presented to the University of Helsinki, Small Animal Teaching Hospital and the Saari Small Animal Clinic between March 2006 and March 2016. Data such as breed, gender, BCS and concurrent diseases were recorded for 123 cats. Statistical analyses were performed using GraphPad Prism. Neutered male cats had 2.8 times the risk of developing diabetes mellitus when compared to intact cats and neutered females. Domestic shorthair cats had 1.7 times the risk of developing diabetes mellitus when compared to other breeds. Remission rates were substantially lower than what has been reported in literature. The results did not support the hypotheses. Cats with an optimal BCS were not more likely to achieve stable disease or remission. However, the small sample size should be taken into consideration when interpreting the results. Investigating the relationship between BCS and diabetes mellitus was difficult due to incomplete documentation of BCS values and limitations of the veterinary patient database. Measures should be taken to develop the database so the evaluation and recording of BCS is a convenient routine. Further research into risk factors for both diabetes mellitus and obesity as well as treatment protocols resulting in remission is needed, so evidence-based data can be used for prevention and remission of the disease.

    Background and aims: In recent years online gambling has become a potential risk for young people. The purpose of this study was to analyse patterns of gambling activities and their association with behavioural risk factors and protective factors. Data and Method: A demographically balanced sample of Finnish respondents aged 15-25 years (N = 1200) filled out an online survey in March-April 2017. Principal component analysis was used to reduce the variables on gambling activities to smaller sets of components, and regression analysis was used to analyse whether behavioural risk factors and protective factors were associated with the gambling patterns found. Results: Two main components were found: online- and skill-based competent gambling and chance-based entertainment gambling. Competent gambling had statistically significant associations with a variety of behavioural problems and risks, including psychological distress, lower social support, lower delay of gratification, hazardous drinking, regular drug use, compulsive Internet use, and problem gambling. Entertainment gambling was associated with lower delay gratification, hazardous drinking, and problem gambling. Entertainment gambling had a negative association with compulsive Internet use and a positive association with social support. Conclusions: Online-based competent gambling is a potentially hazardous form of gambling. New forms of online gambling are potential risks for younger generations. Health professionals working with young people should be aware of the role of online gambling and associated activities.

    BACKGROUND: Coronary artery disease (CAD) is accelerated in subjects with type 2 diabetes mellitus (T2D). METHODS: To test whether this reflects differential genetic influences on CAD risk in subjects with T2D, we performed a systematic assessment of genetic overlap between CAD and T2D in 66 643 subjects (27 708 with CAD and 24 259 with T2D). Variants showing apparent association with CAD in stratified analyses or evidence of interaction were evaluated in a further 117 787 subjects (16 694 with CAD and 11 537 with T2D). RESULTS: None of the previously characterized CAD loci was found to have specific effects on CAD in T2D individuals, and a genome-wide interaction analysis found no new variants for CAD that could be considered T2D specific. When we considered the overall genetic correlations between CAD and its risk factors, we found no substantial differences in these relationships by T2D background. CONCLUSIONS: This study found no evidence that the genetic architecture of CAD differs in those with T2D compared with those without T2D.

    In this study, the association between Eimeria spp. related signs and innate immune response in dairy calves was examined. Calves (n= 100) aged 15-60 days were clinically examined and faecal samples, blood samples and deep nasopharyngeal swabs obtained. The samples were analysed for intestinal pathogens, acute phase proteins and WBC count, and respiratory tract pathogens, respectively. Diarrhoea was diagnosed in 32.6% (23.3-43.0%, 95% CI) of calves. An association between the pathogenic Eimeria spp. and diarrhoea was detected by multiple correspondence analysis. Eimeria related signs (diarrhoea, presence of pathogenic species and total oocyst count) were combined resulting a four level variable. Calves with weak signs of eimeriosis had decreased haptoglobin concentrations (p = 0.02) and increased fibrinogen concentrations (p = 0.048) compared to no signs. Increased haptoglobin and fibrinogen concentrations were associated with respiratory tract infection and umbilical infection. Serum amyloid A and WBC counts showed no association with signs of eimeriosis or clinical diagnoses. (C) 2015 Elsevier Ltd. All rights reserved.

    Background Job strain is implicated in many atherosclerotic diseases, but its role in peripheral artery disease (PAD) is unclear. We investigated the association of job strain with hospital records of PAD, using individual-level data from 11 prospective cohort studies from Finland, Sweden, Denmark, and the United Kingdom. Methods and Results Job strain (high demands and low control at work) was self-reported at baseline (1985-2008). PAD records were ascertained from national hospitalization data. We used Cox regression to examine the associations of job strain with PAD in each study, and combined the study-specific estimates in random effects meta-analyses. We used tau(2), I-2, and subgroup analyses to examine heterogeneity. Of the 139 132 participants with no previous hospitalization with PAD, 32 489 (23.4%) reported job strain at baseline. During 1 718 132 person-years at risk (mean follow-up 12.8 years), 667 individuals had a hospital record of PAD (3.88 per 10 000 person-years). Job strain was associated with a 1.41-fold (95% CI, 1.11-1.80) increased average risk of hospitalization with PAD. The study-specific estimates were moderately heterogeneous (tau(2)=0.0427, I-2: 26.9%). Despite variation in their magnitude, the estimates were consistent in both sexes, across the socioeconomic hierarchy and by baseline smoking status. Additional adjustment for baseline diabetes mellitus did not change the direction or magnitude of the observed associations. Conclusions Job strain was associated with small but consistent increase in the risk of hospitalization with PAD, with the relative risks on par with those for coronary heart disease and ischemic stroke.

    Background: High alcohol consumption is a major cause of morbidity, yet alcohol is associated with both favourable and adverse effects on cardiometabolic risk markers. We aimed to characterize the associations of usual alcohol consumption with a comprehensive systemic metabolite profile in young adults. Methods: Cross-sectional associations of alcohol intake with 86 metabolic measures were assessed for 9778 individuals from three population-based cohorts from Finland (age 24-45 years, 52% women). Metabolic changes associated with change in alcohol intake during 6-year follow-up were further examined for 1466 individuals. Alcohol intake was assessed by questionnaires. Circulating lipids, fatty acids and metabolites were quantified by high-throughput nuclear magnetic resonance metabolomics and biochemical assays. Results: Increased alcohol intake was associated with cardiometabolic risk markers across multiple metabolic pathways, including higher lipid concentrations in HDL subclasses and smaller LDL particle size, increased proportions of monounsaturated fatty acids and decreased proportion of omega-6 fatty acids, lower concentrations of glutamine and citrate (P<0.001 for 56 metabolic measures). Many metabolic biomarkers displayed U-shaped associations with alcohol consumption. Results were coherent for men and women, consistent across the three cohorts and similar if adjusting for body mass index, smoking and physical activity. The metabolic changes accompanying change in alcohol intake during follow-up resembled the cross-sectional association pattern (R-2 = 0.83, slope = 0.7260.04). Conclusions: Alcohol consumption is associated with a complex metabolic signature, including aberrations in multiple biomarkers for elevated cardiometabolic risk. The metabolic signature tracks with long-term changes in alcohol consumption. These results elucidate the double-edged effects of alcohol on cardiovascular risk.
