Kawasaki disease (KD) is an acute febrile systemic vasculitis and has been reported to be associated with allergic disease. The risk of atopic dermatitis (AD) in preschool children with KD has not been investigated. The study was to determine the longitudinal risk of the development of AD in preschool children with KD. A nationwide 5-year population-based study was performed using data from the National Health Insurance Database in Taiwan between 1999 and 2003. The risk factors for AD were compared between the 2 study groups during the follow-up period using the Cox proportional hazards model. In addition, plasma interleukin (IL)-5 levels were analyzed in normal subjects and KD patients. Among the 1440 subjects included, 21.6% developed AD during the 5-year follow-up period, of which 30.3% and 18.7% belonged to the study cohort and the comparison group, respectively. Children with KD were 1.25 times more likely to have AD than those in controls (P=0.04). Levels of IL-5 and IgE were significantly higher in KD patients. Children with KD had a higher risk of developing AD during the 5-year follow-up period than the control group. Increased IL-5 and IgE levels may be key factors contributing to the risk of AD.

BackgroundThe potential relationship between anaesthesia, surgery and onset of dementia remains elusive.AimsTo determine whether the risk of dementia increases after surgery with anaesthesia, and to evaluate possible associations among age, mode of anaesthesia, type of surgery and risk of dementia.MethodThe study cohort comprised patients aged 50 years and older who were anaesthetised for the first time since 1995 between 1 January 2004 and 31 December 2007, and a control group of randomly selected patients matched for age and gender. Patients were followed until 31 December 2010 to identify the emergence of dementia.ResultsRelative to the control group, patients who underwent anaesthesia and surgery exhibited an increased risk of dementia (hazard ratio = 1.99) and a reduced mean interval to dementia diagnosis. The risk of dementia increased in patients who received intravenous or intramuscular anaesthesia, regional anaesthesia and general anaesthesia.ConclusionsThe results of our nationwide, population-based study suggest that patients who undergo anaesthesia and surgery may be at increased risk of dementia.

This study aimed to investigate the association between charcoal-burning suicide attempts and the risk of developing dementia. A nationwide, matched cohort, population-based study enrolled a total of 4103 patients with newly diagnosed charcoal-burning suicide attempts, between 2000 and 2010, which were selected from the National Health Insurance Research Database of Taiwan, along with 12,309 controls matched for sex and age. After adjusting for confounding factors, Fine and Gray’s competing risk analysis was used to compare the risk of developing dementia during the 10-year follow-up period. Of the enrolled patients (n=16,412), dementia developed in 303 (1.85%), including 2.56% in the study group (105 in 4103) and 1.61% (198 in 12,309) in the control group. The Fine and Gray’s survival analysis revealed that the patients with charcoal-burning suicide attempts were likely to develop dementia, with a crude HR of 5.170 (95% CI 4.022 to 6.644, p<0.001). After adjusting for age, sex, comorbidity, geographic area and urbanization level of residence, and monthly insured premium, the adjusted HR was 4.220 (95% CI 3.188 to 5.586, p<0.001). Suicide attempts were associated with an increased risk of degenerative dementia in this study. Patients with charcoal-burning suicide attempts had a fourfold risk of dementia than the control group.

Accumulating evidence has shown a significant correlation between periodontal diseases and systemic diseases. In this study, we investigated the association between the frequency of tooth scaling and acute myocardial infarction (AMI). Here, a group of 7164 participants who underwent tooth scaling was compared with another group of 7164 participants without tooth scaling through propensity score matching to assess AMI risk by Cox’s proportional hazard regression. The results show that the hazard ratio of AMI from the tooth scaling group was 0.543 (0.441, 0.670) and the average expenses of AMI in the follow up period was USD 265.76, while the average expenses of AMI in follow up period for control group was USD 292.47. The tooth scaling group was further divided into two subgroups, namely A and B, to check the influence of tooth scaling frequency on AMI risk. We observed that (1) the incidence rate of AMI in the group without any tooth scaling was 3.5%, which is significantly higher than the incidence of 1.9% in the group with tooth scaling; (2) the tooth scaling group had lower total medical expenditures than those of the other group because of the high medical expenditure associated with AMI; and (3) participants who underwent tooth scaling had a lower AMI risk than those who never underwent tooth scaling had. Therefore, the results of this study demonstrate the importance of preventive medicine.

Abstract Background In the current study, we aimed to investigate the association of dietary inflammation scores (DIS) and lifestyle inflammation scores (LIS) with the risk of metabolic syndrome (MetS) in a prospective population-based study. Methods A total of 1625 participants without MetS were recruited from among participants of the Tehran Lipid and Glucose Study(2006–2008) and followed a mean of 6.1 years. Dietary data of subjects were collected using a food frequency questionnaire at baseline to determine LIS and DIS. Multivariable logistic regression models, were used to calculate the odds ratio (ORs) and 95 % confidence interval (CI) of MetS across tertiles of DIS and LIS. Results Mean ± SD age of individuals (45.8 % men) was 37.5 ± 13.4 years. Median (25–75 interquartile range) DIS and LIS for all participants was 0.80 (− 2.94, 3.64) and 0.48 (− 0.18, − 0.89), respectively. During the study follow-up, 291 (17.9 %) new cases of MetS were identified. Based on the age and sex-adjusted model, a positive association was found between LIS (OR = 7.56; 95% CI 5.10–11.22, P for trend < 0.001) and risk of MetS, however, the association of DIS and risk of MetS development was not statistically significant (OR = 1.30;95% CI 0.93–1.80, P for trend = 0.127). In the multivariable model, after adjustment for confounding variables, including age, sex, body mass index, physical activity, smoking, and energy intake, the risk of MetS is increased across tertiles of DIS (OR = 1.59; 95% CI 1.09–2.33, P for trend = 0.015) and LIS(OR = 8.38; 95% CI 5.51–12.7, P for trend < 0.001). Conclusions The findings of the current study showed that greater adherence to LIS and DIS, determined to indicate the inflammatory potential of diet and lifestyle, are associated with increased the risk of MetS.

BackgroundThe association between autoimmune diseases and schizophrenia has rarely been systematically investigated.AimsTo investigate the association between schizophrenia and a variety of autoimmune diseases and to explore possible gender variation in any such association.MethodTaiwan's National Health Insurance Research Database was used to identify 10 811 hospital in-patients with schizophrenia and 108 110 age-matched controls. Univariate and multiple logistic regression analyses were performed, separately, to evaluate the association between autoimmune diseases and schizophrenia. We applied the false discovery rate to correct for multiple testing.ResultsWhen compared with the control group, the in-patients with schizophrenia had an increased risk of Graves' disease (odds ratio (OR) = 1.32, 95% CI 1.04–1.67), psoriasis (OR = 1.48, 95% CI 1.07–2.04), pernicious anaemia (OR = 1.71, 95% CI 1.04–2.80), celiac disease (OR = 2.43, 95% CI 1.12–5.27) and hypersensitivity vasculitis (OR = 5.00, 95% CI 1.64–15.26), whereas a reverse association with rheumatoid arthritis (OR = 0.52, 95% CI 0.35–0.76) was also observed. Gender-specific variation was found for Sjögren syndrome, hereditary haemolytic anaemia, myasthenia gravis, polymyalgia rheumatica and dermatomyositis.ConclusionsSchizophrenia was associated with a greater variety of autoimmune diseases than was anticipated. Further investigation is needed to gain a better understanding of the aetiology of schizophrenia and autoimmune diseases.

Introduction Better data regarding the incidence and risk factors for sudden cardiac death (SCD) in children with cardiomyopathy (CM) is critical in defining appropriate primary prevention strategies. Methods The National Australian Childhood Cardiomyopathy Study is a prospective cohort study, including all children in Australia with primary CM diagnosed at 0 – 10 years of age, between 1987–1997. SCD was defined as sudden and unexpected death in children who were not hospitalized and not in congestive heart failure at the time of death. Nine subjects with sudden death as presenting symptom were excluded. Indexed echocardiographic measurements at latest follow-up were compared between subjects with SCD and survivors. Results Study criteria were met by 291 children. Mean duration of follow-up was 9.2 years. The incidence of sudden death relative to each CM type, for all cases and as a proportion of deaths, is shown in the Table : Incidence of SCD by CM type. SCD incidence was significantly associated with CM type, for all cases ( p = 0.006) and when only those subjects who died were considered ( p = 0.005), with LVNC and RCM having up to 4 times the risk of other CM types. Children with familial DCM had a significantly higher rate of SCD than subjects with non-familial CM (12% vs 3%; p = 0.028), however, familial CM was not a risk factor in other CM types. DCM SCD subjects had larger LVEDd Z score than survivors (median 5.53 vs 1.16; p <0.0001) and lower FS Z score (median −9.23 vs −0.51; p = 0.0025). HCM SCD subjects had thicker LVPW dimension Z scores than survivors (median 4.63 vs 1.18; p = 0.007). Twelve subjects (2 DCM, 8 HCM and 2 LVNC) underwent ICD implantation (8/12 for primary prevention). Conclusions: This population based study defines new risk factors for sudden death in children with CM. RCM is well known to have a high incidence of SCD. In addition, children with LVNC and those with DCM who have severe dilatation, systolic dysfunction or familial DCM are at increased risk of sudden death.

The Impact

ObjectivesLow testosterone levels in men have been associated with cardiovascular risk factors and atherosclerosis and lately also an increased risk of both cardiovascular disease (CVD) and all-cause mortality. As arterial CVDs and venous thromboembolism (VTE) have been shown to share common risk factors, the purpose of the present study was to determine the impact of endogenous sex hormone levels on the incidence of VTE in a cohort of men.DesignA prospective, population-based study.MethodsSex hormone measurements were available in 1350 men, aged 50–84, participating in the Tromsø study in 1994–1995. First, lifetime VTE-events during the follow-up were registered up to September 1 2007.ResultsThere were 63 incident VTE-events (4.5 per 1000 person-years) during a mean of 10.4 years of follow-up. Age was significantly associated with increased risk of VTE; men 70 years or older had a 2.5-fold higher risk of VTE (HR 2.47, 95% CI 1.19–5.12), compared with those between 50 and 60 years of age. In age-adjusted analyses, endogenous sex hormones levels were not associated with risk of VTE; for each s.d. increase, hazards ratios (95% CI) were 1.06 (0.83–1.35) for total testosterone, 1.02 (0.79–1.33) for free testosterone, and 1.27 (0.94–1.71) for ln-estradiol. In dichotomized analyses comparing men in the lowest total and free testosterone quartile with men in the higher quartiles, hypoandrogenemia was not associated with risk of VTE.ConclusionsIn this population-based study of middle-aged and older men, endogenous sex hormone levels were not associated with 10-year risk of VTE.

Introduction: Genetic susceptibility and immune dysregulation play important roles in the pathogenesis of Kawasaki disease (KD). However, it is still unclear whether KD causes immune disorder later in life or whether inherited susceptibility to immune disorders causes KD. The aim of this study was to elucidate whether inherited immune disease properties from mothers increase the risk of KD from a population-based perspective.Method: Taiwan's National Health Insurance Research Database was the main data source in this study. Parents and children were linked using the Taiwan Maternal and Child Health Database. Patients diagnosed with KD and younger than 18 years from 2004 to 2015 were enrolled as the study population. The control group was randomly selected from individuals without the diagnosis of KD matched by age, index year, sex, and urbanization level at a ratio of 1 to 10. The prevalence of maternal autoimmune and allergic diseases was compared between groups.Results: In total, 7,178 children were found to have been diagnosed with Kawasaki disease. Then 71,780 children matched by index year, gender, and urbanization were randomly selected to serve as the control group. Children born from mothers with asthma and allergic rhinitis had a higher risk of developing KD. Children of mothers with an autoimmune disorder had a significantly increased tendency to develop KD. Maternal numbers of autoimmune disorders showed a dose-dependent relationship with KD incidence.Conclusion: This is the first population-based study to investigate maternal immune diseases and the risk of KD in their children. Children of mothers with immune disorders tend to have a higher risk of KD.

244 Background: Falls and fall-related injuries are important patient safety problems. Some studies suggest that pc patients have higher fall rates, however the severity of these falls is unknown. We sought to measure if pc patients are at increased risk of a debilitating fall requiring hospitalization. Methods: This is a retrospective population-based study utilizing the Manitoba Cancer Registry and Manitoba Health administrative databases. Our cohort consists of all community-dwelling patients living in Manitoba Canada who were diagnosed with pc between 2004 and 2008. These individuals were matched by age, sex, and time of diagnosis with up to three cancer-free controls. Debilitating falls were defined as falls/fractures requiring hospitalization and were identified using ICD-9 and -10 billing codes. A competing risk model was used to compare debilitating falls between the pc and cancer-free cohorts and expressed as sub-hazard ratios. Follow-up ended December 31, 2009. Results: 2,903 pc patients were identified along with 8,686 matched controls. The mean age was 69.3 and 68.8 respectively. The median follow-up was 3.05 years. Debilitating falls were identified in 109 patients (3.8%) with pc and 345 (4%) matched controls. The cumulative incidence of debilitating falls for those with pc vs cancer-free controls were: 1.08% vs. 1.13% at 1-year and 5.25% vs. 5.96% at five years of follow-up (SHR = 0.95, 95% CI = 0.77 – 1.18, p = 0.65). On univariate analysis, patients with stage IV pc were at higher risk of falls compared to matched controls. This difference was not significant on multivariate analysis though (SHR = 1.19, 95% CI = 0.74 – 1.89, p = 0.48). On multivariate analysis, patients with a Gleason score of ≤6 experienced a reduced risk of debilitating falls compared to matched controls (SHR = 0.44, 95% CI = 0.27 – 0.72, p = 0.001), whereas patients with other Gleason scores did not. The analysis was similar when patients with fractures were excluded. Conclusions: In this large population-based study, the 1- and 5-year cumulative incidence of debilitating falls did not differ significantly for patients with vs without pc. In fact, compared to matched controls, low grade pc patients were less likely to experience a debilitating fall.

Abstract Introduction To date, studies have estimated the phenoconversion rate from sleep clinics, using polysomnography proven RBD. However, no population-based estimates have been reported, testing to what degree possible RBD, screened by questionnaire is associated with increased risk of neurodegeneration. Methods We included those aged 45–85 years, living in one of 10 Canadian provinces in between 2012–2015 (at the baseline), recruited via three population-based sampling methods. Dream enactment behavior/possible RBD was screened using the RBD1Q single question-questionnaire. De-novo parkinsonism was defined as free of pre-existing diagnosis at the baseline with a ‘new’ diagnosis at the follow-up (205–2019). Relative risk (log-binomial regression), hazard ratio (Cox regression), incidence rate (Poisson regression) between the affected group and the symptom naïve group were assessed, adjusting for age and sex (and total years of education and language). Results Overall, 58 participants phenoconverted into parkinsonism and 53 into dementia at the follow-up (mean intervals=3.06±0.37 years). Participants with dream enactment behavior had 2.75 times higher risk to phenoconvert into parkinsonism than the symptom-free. Similarly, those with dream enactment behavior at the baseline possessed higher risk to screening positive of parkinsonism. No difference in time to phenoconversion was found between groups, The results remained robust after excluding non-RBD related symptoms, such as apnea and non-REM sleep parasomnia. Conclusion Compared to symptom-free, those with pRBD had higher risk to developing parkinsonism in near future. Support (if any):
