Background and purpose: The association between an increased supraventricular ectopic beat (SVEB) and subclinical cerebrovascular disease remains unclear. Given the emerging concept that an increased SVEB is a marker of atrial cardiomyopathy or atherosclerosis burden, we sought to determine whether excessive supraventricular ectopic activity (ESVEA) is associated with a higher burden of subclinical cerebrovascular disease in the middle-aged to older cohort with neither apparent stroke nor atrial fibrillation. Methods: We conducted a cross-sectional population-based study of 462 men (mean age, 68.1 years) who underwent 24-h Holter electrocardiography and brain magnetic resonance imaging. ESVEA was defined as the presence of >10 SVEBs/h. Subclinical cerebrovascular diseases were defined as silent brain infarct (SBI), white matter hyperintensity (WMH) and intracranial atherosclerotic stenosis (ICAS). The association of ESVEA with the presence of subclinical cerebrovascular diseases was adjusted for potential confounding covariates. Results: A total of 88 (19.0%) participants had ESVEA and 81 (17.5%), 91 (19.7%) and 109 (23.6%) had SBI, WMH and ICAS, respectively. In multivariable-adjusted Poisson regression with robust error variance, ESVEA was associated with the presence of WMH (relative risk, 1.58; 95% confidence interval, 1.06–2.36) and ICAS (relative risk, 1.49; 95% confidence interval, 1.02–2.18), but not with that of SBI (relative risk, 1.32; 95% confidence interval, 0.86–2.01). These associations were consistent when the graded distributions of subclinical cerebrovascular diseases were applied as outcomes in ordinal logistic regression. Conclusions: The ESVEA was independently associated with higher burdens of WMH and ICAS. This suggests that increased SVEBs might improve risk stratification of individuals at high risk of subclinical cerebrovascular disease and consequently apparent ischaemic stroke.

BACKGROUND: School teachers have a possibility toward at-risk Internet addiction (IA) due to increased opportunities to use the Internet, along with the spread of the Internet in recent years. Burnout syndrome (BOS) is found to be one of the symptoms related to unhealthy mental health, especially among teachers. This study aims to research the relationship between at-risk IA and the Internet usage or BOS by conducting a nationwide cross-sectional survey and examining the factors associated with IA. METHOD: This study was a cross-sectional survey by anonymous questionnaire. This survey was a random sampling survey of junior high schools across Japan in 2016. The participants were 1696 teachers at 73 schools (response rate in teachers 51.0%). We asked participants for details of their backgrounds, Internet usage, the Internet Addiction Test (IAT) by Young, and the Japanese Burnout Scale (JBS). We divided the participants into either the at-risk IA group (IAT score ≧ 40, n = 96) or the non-IA group (IAT score < 40, n = 1600). To compare the difference between at-risk IA and non-IA, we used nonparametric tests and t test according to variables. To analyze the relationship between the IAT score and the scores of three factors of the JBS (emotional exhaustion, depersonalization, and personal accomplishment), we used both ANOVA and ANCOVA, adjusted by relevant confounding factors. To clarify the contribution of each independent variable to IAT scores, we used multiple logistic regression analysis. RESULTS: In our study, at-risk IA was associated with using the internet many hours privately, being on the Internet both on weekdays and weekends, playing games, and surfing the Internet. In the relationship between IAT score and BOS factor score, a higher score for "depersonalization" had a positive relationship with at-risk IA, and the highest quartile for "decline of personal accomplishment" had a lower odds ratio with at-risk IA by multiple logistic regression analysis. CONCLUSION: We clarified there is a significant relationship between at-risk IA and BOS among junior high school teachers in a nationwide survey. Our results suggest that finding depersonalization at the early stage may lead to the prevention of at-risk IA among teachers. Those who are at-risk of IA may feel personal accomplishment through use of the Internet.

PurposeDietary behaviors and sleep are important lifestyle factors to protect adolescent health. However, little is known about how dietary behaviors are related to sleep disturbances. The purpose of this study was to conduct a large-scale survey among Japanese adolescents to verify the association between unhealthy dietary behaviors and sleep disturbances.MethodsThis study included 65,688 and 99,581 students enrolled in 140 and 120 randomly selected junior and senior high schools, respectively. A total of 85,931 self-administered questionnaires were collected from 79 junior and 77 senior high schools from 2014 to 2015. The survey included questions on sleep patterns, dietary behaviors, alcohol consumption, and smoking, as well as questions on mental health. For dietary behaviors, we adopted the items on meal habits in the National Health and Nutrition Survey including, the frequency of eating breakfast, the frequency of family meals, and subjective diet quality. We performed a multivariate analysis on the relationship between the dietary behaviors and sleep disturbance.ResultsData from 84,988 questionnaires were analyzed. Boys and girls with less healthy dietary behaviors had a significantly higher prevalence for each sleep disturbance. Subjective sleep quality and insomnia were significantly associated with breakfast frequency, family meal frequency, and diet quality. Short sleep duration was significantly associated with breakfast frequency and family meal frequency, but not with subjective diet quality.ConclusionsOur study suggested that sleep and dietary behaviors affect one another. Those involved in public health education should encourage adolescents to establish healthy sleep patterns as well as healthy dietary behaviors.

In 2018, a new training program for primary care physicians was launched in Japan. As physicians responsible for the training of new primary care physicians, we have faced many problems, particularly in rural areas. The influence of this new program on primary care physicians in rural areas of Japan has not been sufficiently investigated. The aim of this research was to improve training for primary care physicians in Japan by examining training programs in Sweden, where the population challenges are similar to those seen in Japan. In this paper, we will express our opinions and describe the differences in the primary care fostering systems and clinical research training for generalist in Japan and Sweden.

Bio-psychosocial factors of children and adolescents with internet gaming disorder: a systematic review. International journal

Nagisa Sugaya, Tomohiro Shirasaka, Kenzo Takahashi, Hideyuki Kanda

BioPsychoSocial medicine 13 3 - 3 2019

Authorship：Last author Language：English Publishing type：Research paper (scientific journal)

Previous large-scale studies suggest that internet gaming disorder (IGD) among children and adolescents has become an important public concern. Minors are known to be particularly susceptible to problematic internet gaming use owing to age-related underdevelopment of cognitive control. It has been shown that precursors of addictions appear during adolescence; therefore, prevention efforts must be established targeting minors who have their first experience with addictive substances and behaviors during pubescence. Since the DSM-5 classification of IGD in 2013, studies on IGD have drastically increased in number. Thus, we performed an updated review of studies of IGD in children and adolescents to assess the clinical implications of IGD. The search included all publication years, using PubMed, MEDLINE, and PsycINFO. Across studies, the presence of IGD had a negative effect on sleep and schoolwork in minors. Additionally, family factors, including the quality of parent-child relationships, were important social factors in minors with IGD. Brain imaging studies indicate that impaired cognitive control in minors with IGD is associated with abnormal function in the prefrontal cortex and striatum. Persistent pathological online game use from childhood may aggravate abnormal brain function; therefore, preventive care and early intervention are increasingly important. Although extant research supports the effectiveness of cognitive behavioral therapy for minors with IGD, effective psychological intervention for minors with IGD is an urgent issue that requires further research. This review, which presents updated findings of IGD in minors, is expected to contribute to the development of future research and be useful in clinical practice in the field of child and adolescent psychiatry.

Drug and alcohol dependence 193 55 - 62 2018.12

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Hazardous drinking (HD) and heavy episodic drinking (HED) constitute different types of alcohol-related harm. The socioeconomic status (SES) background of various alcohol consumption behaviors is not clear. The purpose of this study was to clarify existing SES differences between HD and HED. METHODS: The 2013 national survey regarding alcohol use among Japanese adults was utilized. The results from 1193 men and 1503 women aged 20-64 years were included in the analysis. Education attainment, household income, marital status, working status, and occupation were adopted as SES determinants. Binomial logistic regression analysis was conducted to estimate the odds ratios (ORs) of HD and HED for each SES group. RESULTS: ORs (95% confidence intervals) of HD were higher among persons with less education among both men [1.61 (1.18-2.20)] and women [1.78 (1.19-2.67)]. The OR of HED in men was significantly higher among those who belonged to high household income, were married, and managers or professionals. The OR of HED among women was higher in persons who were employed, as compared with those who engaged in housework. There were no correlations between HED and educational background. CONCLUSIONS: This study showed that in Japan, a lower educational background for both men and women was associated with a higher risk for HD, while higher current SES for men and working women were associated with a higher risk for HED. It is necessary to recognize the SES differences between HD and HED to achieve a policy to reduce alcohol-related harm.

Language：English Publishing type：Research paper (scientific journal) Publisher：MARY ANN LIEBERT, INC

Because schoolteachers are subject to suffer from mental health problems, this study aimed to examine the relationship between problematic Internet use (PIU) and psychological distress, insomnia, and alcoholism among schoolteachers. The cross-sectional study surveyed junior and senior high school teachers in Shimane prefecture, a rural area in Japan. A total of 2,663 junior and senior high school teachers (1,702 men and 961 women) completed the self-rated questionnaire measuring PIU, psychological distress, insomnia, and alcoholism. The results of hierarchical multiple regression analyses showed that psychological distress, insomnia, and alcoholism were associated with PIU among schoolteachers. The results indicate that schoolteachers with more severe psychological distress, insomnia, or alcoholism, regardless of gender, would use the Internet in a more problematic way. The study suggests that PIU could be an important condition related to multiple health problems in schoolteachers.

Language：English Publishing type：Research paper (scientific journal)

OBJECTIVE: This study investigated the association between secondhand-smoke (SHS) exposure and sleep disturbance symptoms. METHODS: This study was a cross-sectional survey of junior and senior high school students throughout Japan. A total of 85,931 adolescents responded, and 84,988 questionnaires were included in the analysis. RESULTS: Adolescents who had never smoked accounted for 88.0% of respondents; among that group 39.1% reported having been exposed to SHS over the previous week. The results of multiple logistic regression analyses indicated that the adjusted odds ratios for insomnia symptoms such as difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS) and early morning awakening (EMA), as well as sleep disturbance symptoms such as subjectively insufficient sleep and short sleep duration (<6 h), tended to be higher both among never-smoking adolescents with SHS exposure and among smoking adolescents, as compared with never-smoking adolescents without SHS exposure. When adolescents with one or more of DIS, DMS, and EMA were defined as having insomnia, the adjusted odds ratio for insomnia was highest for adolescents who smoked, followed in descending order by those exposed to SHS both inside and outside the home, those exposed to SHS only inside the home, those exposed to SHS only outside the home, and never-smoking adolescents without SHS exposure (p < 0.001). CONCLUSIONS: The present study has revealed that SHS exposure is associated with sleep disturbance. Thus, in addition to smoking cessation programs, it is also necessary to endorse measures to protect adolescents from SHS exposure in order to promote good sleep in this population.

Journal of epidemiology 28 ( 4 ) 202 - 206 2018.4

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: The prevalence of Internet addiction (IA) among employed adults has not been reported using a large sample. To clarify the actual status of addictive Internet use among employed adults, this study aimed to evaluate the prevalence and the risk factors of IA and at-risk IA among employed adults in Japan. METHODS: This cross-sectional study surveyed all junior and senior high school personnel in Shimane Prefecture, a rural area in Japan. Eligible participants included 3,211 junior and senior high school personnel (1,259 men and 1,952 women). Participants completed a questionnaire on their activities and factors related to Internet use. RESULTS: The prevalence of IA and at-risk IA was 0.03% and 4.82%, respectively. Furthermore, game playing was shown to be the Internet activity most closely associated with at-risk IA. CONCLUSIONS: This study showed that around 5% of school personnel in a rural area in Japan are at risk for developing addiction to the Internet and that using the Internet for game playing is related to at-risk IA. Our results suggest that employed adults should be instructed to use the Internet properly.
