Abstract
BACKGROUND Intrauterine exposure to hypertensive disorders of pregnancy (HDP) may increase the risk of neuropsychiatric disorders. This investigation examined for associations between maternal HDP and febrile seizures (FS) in offspring by the age of three years. METHODS The present cohort study analyzed data from the Japan Environment and Children's Study, a large national birth cohort. We included mother-child pairs recruited between January 2011 and March 2014. Information regarding maternal HDP, the presence of FS in offspring up to 3 years of age, and potential confounding factors were assessed using written questionnaires administered to mothers. RESULTS A total of 77,699 mother-child dyads were analyzed. The prevalence of FS was 8.4% in children without HDP exposure, 10.6% in those exposed to mild HDP, and 10.4% in those with severe HDP exposure. Among children with full-term birth, logistic regression analysis indicated that exposure to mild or severe HDP was significantly associated with a higher incidence of FS (adjusted odds ratio [95% confidence interval]: 1.27 [1.05-1.53] and 1.27 [0.90-1.78], respectively, P for trend = 0.008), compared with children without HDP exposure. CONCLUSION In children with full-term birth, intrauterine exposure to HDP was significantly associated with FS by the age of three years. IMPACT This study revealed a significant association between intrauterine exposure to hypertensive disorders of pregnancy (HDP) and the subsequent development of febrile seizures (FS) in offspring by three years. This increased incidence of FS by HDP was independent of preterm birth status. This is the first large nationwide birth cohort study showing the impact of intrauterine exposure to HDP on FS in early childhood.

Abstract
The effects of early-life exposure to per- and polyfluoroalkyl substances (PFAS) on the onset of asthma in children have been unclear. We examined the association between prenatal PFAS exposure and wheezing and asthma symptoms among 4-year-old children in a total of 17,856 mother-child pairs from the Japan Environment and Children's Study. Maternal first-trimester serum concentrations of six PFAS were used for the exposure assessment. We defined "wheeze ever," "current wheeze," "current symptoms of severe asthma," and "asthma ever" at the age of 4 years by the responses to the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire, and "doctor-diagnosed asthma" by the response to a corresponding question. Multivariate logistic regression models were used to examine exposure-outcome associations. Our findings revealed that doubling of the PFOA concentration was associated with a reduced occurrence of "wheeze ever," yielding an adjusted odds ratio of 0.94 (95% CI: 0.90-0.98). Also, doubling in the concentrations of PFOA and PFHxS was associated with a decreased prevalence of "asthma ever," with adjusted odds ratios of 0.94 (95% CI: 0.88-1.00) and 0.95 (95% CI: 0.90-0.99), respectively. However, these associations were not significant after applying the Bonferroni correction. The estimated exposure-response curves were nearly linear with a subtle or flat slope. When stratified by the child's sex or the mother's history of asthma, most of the estimated confidence intervals were overlapped between each pair of strata. Regional stratification analysis indicated low-to-moderate heterogeneity in 12 exposure-outcome pairs and moderate-to-high heterogeneity in 9 out of the 30 examined pairs. This study found no clear associations between prenatal PFAS exposure and the prevalence of wheezing and asthma among children at the age of 4 years.

Abstract
PURPOSE This investigation assessed the impact of dog and/or cat ownership during infancy on the presence of functional constipation (FC) at 3 years of age. METHODS The fixed data of 73,936 singleton births from a large national birth cohort study commencing in 2011 were used to identify FC as estimated by Rome III at 3 years of age. Multiple logistic regression analysis was employed to search for correlations between FC development and dog and/or cat ownership in early childhood. RESULTS A total of 8,459 toddlers (11.6%) met the Rome III criteria for FC at 3 years of age. Overall, 57,264 (77.5%) participants had never owned a dog or cat. We identified 7,715 (10.4%) infant-period owners, 1,295 (1.8%) current owners, and 7,762 (10.5%) long-term owners. Multivariate analysis showed that infant-period ownership remained significantly associated with the risk of developing FC at 3 years of age after adjusting for covariates (adjusted OR [95% CI] 1.09 [1.01-1.19] based on non-ownership). CONCLUSIONS This Japanese large nationwide survey uncovered a possible adverse effect of infant-period dog and/or cat ownership prior to 6 months of age on FC status at 3 years of age.

Abstract
OBJECTIVES To investigate the association between the number of teeth and the new onset of pre-diabetes. DESIGN Retrospective cohort study. SETTING The National Database of Health Insurance Claims and Specific Health Checkups of Japan, which holds information from both the yearly health check-up programme known as the 'Specific Health Checkup' and health insurance claims data. PARTICIPANTS 1 098 371 normoglycaemic subjects who participated in the Specific Health Checkup programme every year from fiscal year (FY) 2015 to FY 2018 and had dental insurance claims data with a diagnosis of periodontal disease during FY 2016. OUTCOME MEASURES Incidence of pre-diabetes or diabetes observed at the Specific Health Checkup during FY 2018. RESULTS Among the participants, 1 77 908 subjects developed pre-diabetes, and 579 developed diabetes at the check-up during the subsequent follow-up year. Compared with the subjects with 26-28 teeth, those with 20-25, 15-19 or 1-14 teeth were associated with an increased likelihood of developing pre-diabetes or diabetes onset with adjusted ORs of 1.03 (95% CI: 1.02 to 1.05), 1.06 (1.03 to 1.09) and 1.07 (1.04 to 1.11), respectively. No clear modifications were observed for age, sex, body mass index or current smoking. CONCLUSIONS Having fewer teeth was associated with a higher incidence of pre-diabetes. Due to the limitations of this study, however, causality remains undetermined.

Abstract
BACKGROUND There is a lack of large, nationwide, birth cohort studies in Japan that examine the relationships of initial feeding habits and breastfeeding period duration with offspring functional constipation at 3 years of age. This study assessed the impact of breastfeeding during infancy on early childhood functional constipation. METHODS The fixed data of 70,078 singleton births from the ongoing Japan Environment and Children's Study cohort study that commenced in 2011 were used to identify functional constipation as estimated by Rome III at 3 years of age. The exposure variables were breastfeeding period duration until 12 months of age (never, up to 6 months, or ≥ 7 months) as well as breastfeeding status at 1 month and 6 months of age (breastfeeding exclusively, partial breastfeeding, or infant formula feeding only). Multiple logistic regression analysis was employed to search for correlations for functional constipation development with breastfeeding period duration until 12 months of age and breastfeeding status during infancy. RESULTS We identified 8,118 toddlers (11.6%) who met the Rome III criteria at 3 years of age. After controlling for potential covariates, a breastfeeding period duration of 7 months or more was inversely related to functional constipation development (≥ 7 months: adjusted odds ratio [OR] [95% confidence interval (CI)] 0.76 [0.65, 0.88] versus never breastfed, P for trend < 0.001). Other initial feeding methods were significantly related to an increased risk of functional constipation as compared with breastfeeding exclusively at 1 month of age (partial breastfeeding: adjusted OR [95% CI] 1.17 [1.11, 1.23], formula feeding only: 1.23 [1.07, 1.40]) and 6 months of age (partial breastfeeding: adjusted OR [95% CI] 1.18 [1.12, 1.24], formula feeding only: adjusted OR [95% CI] 1.42 [1.20, 1.68]). CONCLUSION This large nationwide survey revealed a possible protective effect of a prolonged breastfeeding period duration and early exclusive breastfeeding in infancy on functional constipation at 3 years.

Abstract
Liquefied sake lees, a by-product of Japanese sake, is rich in Saccharomyces cerevisiae, proteins, and prebiotics derived from rice and yeast. Previous studies have reported that Saccharomyces cerevisiae fermentation products improved the health, growth, and faecal characteristics of preweaning calves. This study investigated the effects of adding liquefied sake lees to milk replacer on the growth performance, faecal characteristics, and blood metabolites of preweaning Japanese Black calves from 6 to 90 days of age. Twenty-four Japanese Black calves at 6 days of age were randomly assigned to one of three treatments: No liquefied sake lees (C, n = 8), 100 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (LS, n = 8), and 200 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (HS, n = 8). The intake of milk replacer and calf starter, as well as, the average daily gain did not differ between the treatments. The number of days counted with faecal score 1 in LS was higher than in HS (P < 0.05), while the number of days with diarrhoea medication in LS and C was lower than HS (P < 0.05). The faecal n-butyric acid concentration tended to be higher in LS compared to C (P = 0.060). The alpha diversity index (Chao1) was higher in HS than in C and LS at 90 days of age (P < 0.05). The principal coordinate analysis (PCoA) using weighted UniFrac distance showed that the bacterial community structures in faeces among the treatments at 90 days of age were significantly different (P < 0.05). The plasma β-hydroxybutyric acid concentration, an indicator of rumen development, was higher for LS than in C throughout the experiment (P < 0.05). These results suggested that adding liquefied sake lees up to 100 g/d (on a fresh matter basis) might promote rumen development in preweaning Japanese Black calves.

Abstract
BACKGROUND The effectiveness of the long-term care service in Japan has been unclear, and most of the relevant studies of this service have been limited to a single region and relatively small samples, necessitating large-scale studies. We examined the associations between long-term care service use and the service/care-need level progression at the national scale in Japan. METHODS We conducted a nationwide retrospective cohort study using data from the Japanese Long-Term Care Insurance Claims database. Individuals aged ≥ 65 years and newly certified as being at the support-need level 1 or 2 or the care-need level 1 between April 2012 and March 2013 were included. We first conducted 1:1 propensity score matching and then examined the associations between service use and the progression in support-need or care-need levels by using Kaplan-Meier survival curves and log-rank tests. RESULTS The final sample consisted of 332,766 individuals. We observed that service use was associated with a faster decline in the support/care-need level, although the differences in the subjects' survival rate diminished; the log-rank test showed significance (p < 0.001). When stratified for urban-rural classifications or regions of Japan, the results were similar to the primary analysis in all of the stratified groups, and no clear regional variations were observed. CONCLUSION We did not observe a clear beneficial effect of receiving long-term care in Japan. Our results suggest that Japan's current long-term care service may not be effective for the recipients of these services. Considering that the system is becoming a financial burden, a re-examination of the service to provide more cost-effective care may be advisable.

Abstract
There have been few studies in non-western countries on the relationship between low levels of daily fine particulate matter (PM2.5) exposure and morbidity or mortality, and the impact of PM2.5 concentrations below 15 μg/m3, which is the latest World Health Organization Air Quality Guideline (WHO AQG) value for the 24-h mean, is not yet clear. We assessed the associations between low-level PM2.5 exposure and cardiorespiratory admissions in Japan. We collected the daily hospital admission count data, air pollutant data, and meteorological condition data recorded from April 2016 to March 2019 in 139 Japanese cities. City-specific estimates were obtained from conditional logistic regression models in a time-stratified case-crossover design and pooled by random-effect models. We estimated that every 10-μg/m3 increase in the concurrent-day PM2.5 concentration was related to a 0.52% increase in cardiovascular admissions (95% CI: 0.13-0.92%) and a 1.74% increase in respiratory admissions (95% CI: 1.41-2.07%). These values were nearly the same when the datasets were filtered to contain only daily PM2.5 concentrations <15 μg/m3. The exposure-response curves showed approximately sublinear-to-linear curves with no indication of thresholds. These associations with cardiovascular diseases weakened after adjusting for nitrogen dioxide or sulfur dioxide, but associations with respiratory diseases were almost unchanged when additionally adjusted for other pollutants. This study demonstrated that associations between daily PM2.5 and daily cardiorespiratory hospitalizations might persist at low concentrations, including those below the latest WHO AQG value. Our findings suggest that the updated guideline value may still be insufficient from the perspective of public health.

Abstract
The short-term association between ambient air pollution and hospital admissions for ischemic stroke is not fully understood. We examined the association between four regularly measured major ambient air pollutants, i.e., sulfur dioxide (SO2), nitrogen dioxide (NO2), photochemical oxidants (Ox), and particulate matter with aerodynamic diameters ≤ 2.5 μm (PM2.5), and hospital admissions for ischemic stroke by analyzing 3 years of nationwide claims data from 97 cities in Japan. We first estimated city-specific results by using generalized additive models with a quasi-Poisson regression, and we obtained the national average by combining city-specific results with the use of random-effect models. We identified a total of 335,248 hospital admissions for ischemic stroke during the 3-year period. Our analysis results demonstrated that interquartile range increases in the following four ambient air pollutants were significantly associated with hospital admissions for ischemic stroke on the same day: SO2 (1.05 ppb), 1.05% (95% CI: 0.59-1.50%); NO2 (6.40 ppb), 1.10% (95% CI: 0.61-1.59%); Ox (18.32 ppb), 1.43% (95% CI: 0.81-2.06%); and PM2.5 (7.86 μg/m3), 0.90% (95% CI: 0.35-1.45%). When the data were stratified by the hospital admittees' medication use, we observed stronger associations with SO2, NO2, and PM2.5 among the patients who were taking antihypertensive drugs and weaker associations with SO2, NO2, and Ox among those taking antiplatelet drugs. Short-term exposure to ambient air pollution was associated with increased hospital admissions for ischemic stroke, and medication use and season may modify the association.

Abstract
BACKGROUND Various genetic and environmental influences have been studied for developmental disorders; however, the precise cause remains unknown. This study assessed the impact of maternal serum total cholesterol (TC) level in early pregnancy on early childhood neurodevelopment. METHODS The fixed data of 31,797 singleton births from a large national birth cohort study that commenced in 2011 were used to identify developmental disorders as estimated by Ages and Stages Questionnaire, third edition (ASQ-3) scores of less than -2 standard deviations at 12 months of age. Multiple logistic regression analysis was employed to search for correlations between possibility of developmental disorders and maternal TC levels in early pregnancy classified into 4 groups based on quartile (Q1-Q4) values. RESULTS After controlling for potential confounding factors in 27,836 participants who ultimately underwent multivariate analysis, we observed that elevated TC levels were significantly associated with a higher risk of screen positive status for communication (Q4: adjusted odds ratio [aOR] 1.20, 95% confidence interval [CI] 1.05-1.37) and gross motor (aOR 1.13, 95% CI 1.03-1.25) ASQ-3 domain scores. CONCLUSION This large nationwide survey revealed a possible deleterious effect of hypercholesterolemia in early pregnancy on infant neurodevelopment and age-appropriate skill acquisition at 12 months age.

Abstract
BACKGROUND Maternal exposure to pesticides during pregnancy may cause oxidative hemolysis leading to neonatal hyperbilirubinemia. This investigation examined for associations between maternal use of pesticides or repellents during pregnancy and neonatal hyperbilirubinemia requiring phototherapy. METHODS We used the dataset from the Japan Environment and Children's Study, a large national birth cohort study registered from January 31, 2011 to March 31, 2014. The fixed data of 61,751 live births were used to evaluate the presence of neonatal hyperbilirubinemia and potential confounding factors. We employed multiple logistic regression analysis to identify correlations between the frequency of maternal pesticide or repellent use during pregnancy and clinically relevant neonatal hyperbilirubinemia. RESULTS After controlling for confounding factors, there were significant associations between neonatal hyperbilirubinemia necessitating phototherapy and the frequent use of indoor insecticide spray (OR 1.21, 95% CI 1.05-1.38). For spray- or lotion-type insect repellents, an opposite relationship was observed (more than a few times a week: OR 0.70, 95% CI 0.61-0.81, up to a few times a month: OR 0.84, 95% CI 0.78-0.91). CONCLUSION The frequent use of indoor insecticide spray during pregnancy showed an increased risk of neonatal hyperbilirubinemia requiring phototherapy, which was absent for spray- or lotion-type insect repellents. IMPACT The frequent use of indoor insecticide spray during pregnancy showed an increased risk of neonatal hyperbilirubinemia requiring phototherapy, which was absent for spray- or lotion-type insect repellents. This is the first study examining the effects of maternal exposure to pesticides or repellents on clinically relevant neonatal hyperbilirubinemia using a dataset from a nationwide birth cohort study. This large-scale Japanese cohort study revealed that the frequent use of indoor insecticide spray during pregnancy may increase the risk of neonatal hyperbilirubinemia requiring treatment.

Abstract
BACKGROUND The association between fetal exposure to alcohol and congenital structural disorders remains inconclusive. The present study searched for relationships between maternal alcohol consumption during pregnancy and the risk of congenital malformations. METHODS We evaluated the fixed dataset of a large national birth cohort study including 73,595 mothers with a singleton live birth. Information regarding the alcohol consumption of mothers was obtained from self-reported questionnaires. Physicians assessed for 6 major congenital malformations (congenital heart defects [CHDs], male genital abnormalities, limb defects, cleft lip and/or cleft palate [orofacial clefts (OFC)], severe brain abnormalities, and gastrointestinal obstructions) up to 1 month after birth. Multiple logistic regression analysis was performed to identify associations between maternal alcohol consumption during pregnancy and each malformation. RESULTS The prevalence of maternal drinking in early pregnancy and until the second/third trimester was 46.6% and 2.8%, respectively. The onset of CHD was inversely associated with mothers who quit drinking during early pregnancy (OR 0.85, 95% CI 0.74-0.98). There was no remarkable impact of maternal drinking habit status on the other congenital malformations after adjustment for covariates. CONCLUSIONS Maternal alcohol consumption during pregnancy, even in early pregnancy, displayed no significant adverse impact on congenital malformations of interest. IMPACT This large-scale Japanese cohort study revealed that no teratogenic associations were found between maternal retrospective reports of periconceptional alcohol consumption and congenital malformations after adjustment for covariates. This is the first nationwide birth cohort study in Japan to assess the effect of maternal alcohol consumption during pregnancy on major congenital malformations. Our finding indicated that maternal low-to-moderate alcohol consumption during pregnancy, even in early pregnancy, displayed no significant adverse impact on congenital heart defects, male genital abnormalities, limb defects, orofacial clefts, severe brain abnormalities, or gastrointestinal obstructions.

Abstract
This study investigated the preventive effects of lactoferrin (LF) on subjective acute gastrointestinal symptoms during the winter in a randomized, double-blinded, placebo-controlled parallel-group comparative trial. The eligible subjects were healthy adults working at kindergartens and nursery schools. We randomized the subjects to the Placebo group (0 mg/day), the Low LF group (200 mg/day), and the High LF group (600 mg/day) for 12 weeks. The prevalence of acute gastrointestinal symptoms was significantly lower in the High LF (13/112 vs. 26/116; p = 0.030) and the Low LF (13/107 vs. 26/116; p = 0.040) groups than in the Placebo group. The adjusted odds ratio for the prevalence of acute gastrointestinal symptoms was 2.78 (95% CI: 1.19–6.47) in the Placebo group compared with the High LF group. LF is useful to prevent acute gastrointestinal symptoms among childcare workers, who mainly consist of women.

Abstract
Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology that affects mostly young women. Multiorgan complications and prolonged treatment significantly cause physical and mental stress in patients. Improving patients’ quality of life (QOL) in SLE treatment is essential. We examined the treatment effects on disease activity and QOL of SLE patients.Objectives:In recent years, lupus low disease activity state (LLDAS) has been proposed as a treatment target for SLE. Patients who achieve LLDAS have a low recurrence rate for lupus and a low risk of serious complications (1). The aim of this study is to investigate whether achieving LLDAS reduces not only recurrence rate and complications of SLE but also improves patients’ QOL.Methods:A total of 104 SLE patients were enrolled in our prospective SLE registry study (Juntendo, Multi-center, Prospective cohort for investigation of clinical course and outcome in SLE: JUMP) conducted at our institution. SLE was diagnosed using the American College of Rheumatology (ACR) 1982 criteria (revised in 1997). QOL was evaluated using the standard version of the 36-item short form health survey version 2 (SF36v2). Participants were divided into the LLDAS achievement and non-achievement groups, and the characteristics of each group including results of SF36v2 were examined.Results:This study included 104 SLE patients, 94 female and 10 male, and the average age and disease duration were 46.4±13.8 and 14.5±11.3 years, respectively. The average corticosteroid dose was 8.0±17.4 mg/day in terms of prednisolone, and anti-dsDNA antibody titer was 16.8±38.5 IU/ml. Of the 104 patients, 57 achieved LLDAS. The subscale’s standard scoring using SF36v2 for role physical (RP) was 78.9±24.0 and 64.6±27.6 (P<0.01), general health (GH) was 50.0±17.0 and 42.0±19.3 (P<0.05), vitality (VT) was 55.8±15.8 and 38.0±24.1 (P<0.01), social functioning (SF) was 82.0±20.7 and 66.5±26.3 (P<0.01), role emotional (RE) was 89.0±16.1 and 73.4±28.1 (P<0.01), and mental health (MH) was 72.4±15.9 and 58.3±21.8 (P<0.01) in the LLDAS achievement and non-achievement groups, respectively. Furthermore, scoring based on the national standard value in the LLDAS achievement group showed that two categories were >50. However, in the LLDAS non-achievement group, all categories were <50. In particular, RP, GH, VT, SF, RE, and MH of the LLDAS achievement group had significantly higher scores than the LLDAS non-achievement group (RP and GH: p<0.05 and VT, SF, RE and MH: p<0.01).Conclusion:Results of examining the association between LLDAS and QOL using SF36v2 in SLE patients showed that patients who achieved LLDAS had significantly better standard statistical scores in many subscale categories. Thus, LLDAS achievement as a treatment target for SLE patients greatly contributes to improving patients’ QOL.References:[1]Franklyn K, et al.

Abstract
Mount Ontake in Nagano Prefecture, Japan erupted on 27 September 2014. Many police officers were called in for duty as a disaster-support task force. We investigated the association between the peritraumatic situation and posttraumatic stress disorder (PTSD) symptoms in these police officers. In January 2015, a health survey (OHS) on disaster stress related to the Mt. Ontake eruption disaster support work was distributed to all of the police officers and staff involved in the disaster support. We analyzed the 213 participants who had PTSD symptoms following the eruption and no missing OHS data. Logistic regression analyses were conducted to clarify the relationship between the participants' symptom severity and their peritraumatic situation (i.e., stressors and daily support prior to the eruption, disaster-support work duties, and postdisaster stress relief). The symptom severity was associated with 'more than seven cumulative days at work' (odds ratio [OR] = 2.47, 1.21-5.06), 'selecting drinking and/or smoking as stress relief after disaster-support work' (OR = 2.35, 1.09-5.04), and 'female' (OR = 3.58, 1.19-10.77). As disaster-support work, 'supporting the victims' families' (OR = 1.99, 0.95-4.21) tended to be associated with symptom severity. The number of days of disaster-support work, stress-relief behavior, and gender were associated with the severity of PTSD symptoms.

Abstract
To evaluate the effects of bovine lactoferrin (LF)-containing yogurt on gastroenteritis in nursery school children during the winter season, we conducted a randomized prospective study. A total of 1296 children were randomized into a group in which LF was provided in yogurt (LF group, n = 661) and a non-LF consumption group (control group, n = 635). The LF group was given LF-containing yogurt (100 mg/day) on all 5 weekdays for approximately 15 weeks, and the control group consumed fruit jelly instead of the yogurt. The final totals of 578 children as the LF group and 584 as the control group were analyzed. The total number of children who were absent from school due to vomiting was significantly lower in the LF group compared to the control, accounting for ≥3 days in any week: 10/234 (4.3%) vs. 49/584 (8.4%), respectively; p = 0.04. Regarding the relationship between absences due to vomiting and the consumption of the LF-containing yogurt, the adjusted odds ratio for absence due to vomiting was 2.48 (95% CI: 1.19–5.14) in the LF children who consumed LF-containing yogurt ≤2 days/week compared to the LF children who consumed the yogurt ≥ 3 days/week. The consumption of LF-containing yogurt (100 mg/day) for ≥3 days/week might help alleviate the symptom of vomiting in nursery school children during the winter.

Abstract
Objective: We investigated the effects of lactoferrin (LF)-fortified formula on acute gastrointestinal and respiratory symptoms in children. Design: Randomized, double-blind, placebo-controlled trial. Setting and subjects: Children aged 12-32 months in Japan. Intervention: Intake of placebo or LF (48 mg/day)-fortified formula for 13 weeks. Primary endpoint: Prevalence of acute gastrointestinal and respiratory symptom. Results: One hundred nine participants were randomized. Eight participants were lost to follow-up, withdrew consent, or were deemed inappropriate for the trial, with 101 participants receiving complete analyses (placebo group, n = 48; LF group, n = 53). Outcomes: The prevalence of acute gastrointestinal symptoms was significantly less in the LF group (22/53 [41.5%]) than in the placebo group (30/48 [62.5%], p = 0.046). The total number of days having acute respiratory symptoms was significantly lower in the LF group (9.0) than in the placebo group (15.0, p = 0.030). Harms: The rate of adverse events was similar between the groups. No adverse drug reactions were found. Conclusions: LF intake decreased the prevalence of acute gastrointestinal symptoms in children aged 12-32 months.

Abstract
PURPOSE To investigate preliminarily the effect of lactoferrin (LF)-fortified formula on sleep conditions in children. STUDY DESIGN A preliminary, randomized, double-blind, placebo-controlled trial. METHODS Healthy children between the ages of 12 and 32 months who attended nursery schools in Japan were divided into two groups and assigned a placebo or LF (48 mg/day)-fortified formula. Children's sleep conditions were investigated before and after the 13-week intervention using the Japanese Sleep Questionnaire for Preschoolers (JSQ-P). RESULTS Altogether, 109 participants were randomized. Eight participants were eliminated due to lost to follow-up, withdrawal of consent, and ineligibility, with 101 participants (placebo, n = 48; LF, n = 53) included in the full analysis set (FAS) and used for analysis. Wake-up time, bedtime, and nighttime sleep were comparable between the two groups before and after intervention. The change in total JSQ-P T scores tended to improve in the LF group (placebo vs LF: 0.5 ± 6.5 vs -1.9 ± 6.1, p = 0.074), in particular, morning symptoms significantly improved (grumpy in the morning, hard to wake-up, and hard to get out of bed) (placebo vs LF: 0.8 ± 6.2 vs -1.9 ± 6.2, p = 0.028). A better trend was also observed in the LF group regarding restless legs syndrome (RLS)-motor (rubs feet at night and touches feet at night) (placebo vs LF: 2.3 ± 10.7 vs -0.6 ± 13.5, p = 0.083) and insufficient sleep (stays up more than one hour later the day before a holiday and wakes up more than one hour later on a holiday) (placebo vs LF: 0.1 ± 9.8 vs -1.7 ± 8.8, p = 0.095). No adverse drug reactions were found. CONCLUSION LF intake may improve sleep condition, especially morning symptoms in children above one year of age.

Abstract
Objective To investigate the effects of lactoferrin (LF) on subjective skin conditions in winter. Design A preliminary, randomized, double-blinded, placebo-controlled trial. Setting and subjects Healthy adults in Japan. Interventions Intake of placebo, 200 mg, or 600 mg of LF for 12 weeks in winter. Endpoints Changes in the scores of subjective skin conditions. Results Three hundred and forty-six subjects were randomized. Nine subjects (placebo, n=0; 200 mg, n=5; 600 mg, n=4) withdrew consent, and 7 subjects (placebo, n=4; 200 mg, n=2; 600 mg, n=1) were lost to follow-up, resulting in 330 for a full analysis set. Outcomes Changes in the scores of moisture were greater in the 600 mg group than in the placebo group. Changes in the scores of moisture were greater in the 200 mg and 600 mg groups, and of texture were greater in the 600 mg group than in the placebo group in female subjects. Conclusion Intake of LF may improve moisture or texture of skin in winter.

Abstract
There have been no large nationwide birth cohort studies examining for the effects of maternal alcohol use during pregnancy on placental abnormality. This study searched for associations between alcohol consumption and the placental abnormalities of placenta previa, placental abruption, and placenta accreta using the fixed dataset of a large national birth cohort study commencing in 2011 that included 80,020 mothers with a singleton pregnancy. The presence of placental abnormalities and potential confounding factors were recorded, and multiple logistic regression analysis was employed to search for correlations between maternal alcohol consumption during pregnancy and placental abnormalities. The overall rate of prenatal drinking until the second/third trimester was 2.7% (2,112). The prevalence of placenta previa, placental abruption, and placenta accreta was 0.58% (467), 0.43% (342), and 0.20% (160), respectively. After controlling for potential confounding factors, maternal alcohol use during pregnancy was significantly associated with the development of placenta accreta (OR 3.10, 95%CI 1.69-5.44). In conclusion, this large nationwide survey revealed an association between maternal drinking during pregnancy and placenta accreta, which may lead to excessive bleeding during delivery.

Abstract
Abstract
Background
Little is known about the effect of additional resection for a frozen-section-positive distal bile duct margin (DM) in perihilar cholangiocarcinoma.
Methods
Patients who underwent surgical resection for perihilar cholangiocarcinoma between 2001 and 2015 were analysed retrospectively, focusing on the DM.
Results
Of 558 consecutive patients who underwent frozen-section examination for a DM, 74 (13·3 per cent) had a frozen-section-positive DM with invasive cancer or carcinoma in situ. Eventually, 53 patients underwent additional resection (bile duct resection in 44 and pancreatoduodenectomy in 9), whereas the remaining 21 patients did not. Ultimately, R0 resection was achieved in 30 of the 53 patients (57 per cent). No patient who underwent additional resection died from surgical complications. The 44 patients with additional bile duct resection had a 5-year overall survival rate of 31 per cent. Overall survival of the nine patients who had pancreatoduodenectomy was better, with a 10-year rate of 67 per cent. Survival of the 21 patients without additional resection was dismal: all died within 5 years. Multivariable analyses identified nodal status and additional resection as independent prognostic factors (lymph node metastasis: hazard ratio (HR) 2·26, 95 per cent c.i. 1·26 to 4·07; bile duct resection versus no additional resection: HR 0·32, 0·17 to 0·60; pancreatoduodenectomy versus no additional resection: HR 0·08, 0·02 to 0·29).
Conclusion
Additional resection for frozen-section-positive DM in perihilar cholangiocarcinoma frequently yields R0 margins. It offers a better chance of long-term survival, and thus should be performed in carefully selected patients.

Abstract
Site-directed RNA editing is an important technique for correcting gene sequences and ultimately tuning protein function. In this study, we engineered the deaminase domain of adenosine deaminase acting on RNA (ADAR1) and the MS2 system to target-specific adenosines, with the goal of correcting G-to-A mutations at the RNA level. For this purpose, the ADAR1 deaminase domain was fused downstream of the RNA-binding protein MS2, which has affinity for the MS2 RNA. To direct editing to specific targets, we designed guide RNAs complementary to target RNAs. The guide RNAs directed the ADAR1 deaminase to the desired editing site, where it converted adenosine to inosine. To provide proof of principle, we used an allele of enhanced green fluorescent protein (EGFP) bearing a mutation at the 58th amino acid (TGG), encoding Trp, into an amber (TAG) or ochre (TAA) stop codon. In HEK-293 cells, our system could convert stop codons to read-through codons, thereby turning on fluorescence. We confirmed the specificity of editing at the DNA level by restriction fragment length polymorphism analysis and sequencing, and at the protein level by western blotting. The editing efficiency of this enzyme system was ~5%. We believe that this system could be used to treat genetic diseases resulting from G-to-A point mutations.

Abstract
We report our initial experience of stenting for symptomatic stenoses of the proximal vertebral artery. A total of 25 lesions affecting the proximal vertebral artery were treated by PTA with stent in 23 patients. The lesions involved the vertebral artery ostium in 20 lesions and the nonostial V1 portion in five lesions. The mean stenosis rate of those lesions was 81% pre-stenting and was reduced to 4% post-stenting. There were two transient neurological complications: hemiparesis in one patient and visual acuity disturbance in another. Angiographic follow-up studies more than three months after treatment demonstrated restenosis in three patients. One of these patients was symptomatic. These restenoses were successfully treated by PTA. Our initial results demonstrated that stenting is a feasible and safe method of treating stenosis of the proximal vertebral artery.

Abstract
Certain attitudes toward suicide may be a risk factor for suicide among the bereaved. To explore this possibility, we examined the relationship between attitudes toward suicide and family history of suicide. We focused on two specific attitudes indicating resignation in a survey: #1 "When a person chooses to die by suicide, the suicide is inevitable" (i.e., inevitability belief); and #2 "A suicide cannot be stopped by any person, because suicide is unpreventable" (i.e., unpreventable belief). The data of 5117 fully completed questionnaires were analyzed. Logistic regression analysis revealed that the two attitudes of resignation were significantly associated with a family history of suicide. The adjusted odds ratio for #1 was 1.39 (95% CI, 1.07-1.79) for individuals having experienced suicide by a family member or relative, while that for #2 was 1.57 (95% CI, 1.27-1.95) for experiencing a suicide by a family member or relative and 1.25 (95% CI, 1.05-1.49) for experiencing a suicide by a friend, business associate, partner or other. These two attitudes of resignation toward suicide were significantly associated with a family history of suicide. These attitudes might increase suicide risk among the bereaved.

Abstract
Objectives: We aimed to assess the exposure of offset printing workers to hazardous substances in the rinsing processes of small-sized companies using a control banding method. Methods: We obtained half-year amounts of hazardous substances purchased through a questionnaire survey and the hazardous information from the safety data sheets (SDSs) and related literature. Results: The amount of petroleum kerosine and carbon hydride markedly increased in 2013 compared with that in 2010. In contrast, the amount of dichloromethane (DCM) decreased in 2013, and 1,2-dichloropropane (DCP) was not used in either 2010 or 2013. Mineral oil and xylene were allocated to Hazard Group D and judged to require Control Approach 3. In addition to DCM with Global Harmonization System's carcinogenic category 1, mildly treated mineral oil and solvent naphtha, allocated into Hazard Group E, are carcinogenic to humans and were judged to require Control Approach 4. There are two limitations of the control banding assessment: first, only limited and scarce hazard information could be obtained from SDSs, and second, safe-sided judgment for control technology for industrial hygiene. Conclusion: Small-sized enterprises are encouraged to implement control banding assessment for hazardous substances and to access expert advice available from Regional Industrial Health Centers. Easy access to appropriate expert advice is important to compensate for the limited and scarce hazard information and safe-sided judgment for control technology for Control Approaches 3 and 4.

Abstract
OBJECTIVES Students' depressive symptoms might be related to their own risk factors and to their parents' status. The objective of this cross-sectional study was to examine the relationship of depressive symptoms with lifestyle variables and parents' psychological and socio-demographic status among Japanese junior high school students. METHODS Of 477 students and their parents, 409 (85.7 %) students and 314 (65.8 %) parents participated in the study. Students answered self-reported questionnaire on depressive symptoms, their heights and weights, subjective stress, body dissatisfaction, lifestyles including sleep duration and extracurricular physical activity in school and other physical activity outside the school, and nutritional intake. Parents responded to questionnaire on depressive symptoms and socio-demographic status. RESULTS The prevalence of depressive symptoms was 24.9 %. Students with depressive symptoms were more likely to have stress. Students in shorter and longer sleep duration groups were more likely to have depressive symptoms. The students with depressive symptoms had smaller amount of energy intake than did those without depressive symptoms. Multiple logistic regression analysis revealed significant relationships between students' depressive symptoms and some independent variables. Sex, subjective stress, "almost-never"-categorized extracurricular physical activity in school and other physical activity outside the school, and having a parent with depressive symptoms were significantly associated with students' depressive symptoms. CONCLUSION Reducing mental stress and taking care of lifestyles, especially, "almost-everyday"-categorized extracurricular physical activity in school and other physical activity outside the school, may have benefits for students' mental health, and having a parent with depressive symptoms may be associated with students' depressive symptoms.

Abstract
OBJECTIVES Feeling ashamed for seeking help when distressed is known to be a critical factor promoting suicidal behaviors. The objective of this study was to examine the relationship between suicidal ideation and psychosocial factors, including worries or anxieties, having a person to confide in, feeling ashamed for seeking help when distressed, and K6 score. METHODS Fourteen out of 77 municipalities from Nagano Prefecture participated in this questionnaire survey. Participants of both sexes over 20 years of age were randomly selected according to age distribution in each municipality. Association between suicidal ideation and sociodemographic and psychosocial factors, including "feeling ashamed for seeking help", were determined by multiple logistic regression analysis. RESULTS Among a total of 11,100 participants, 7394 (66.6%) returned the questionnaire. 2147 participants responded properly to essential study parameters and were submitted to the final analyses. The adjusted odds ratio of suicidal ideation was 2.09 (95% CI 1.49-2.94) among participants feeling ashamed for seeking help, compared to those not feeling ashamed. Although the rate of "no person to confide in" was 4.4%, participants who responded with "no person to confide in" had significantly increased odds ratio of suicidal ideation compared with those who responded with "having a person to confide in" (OR 1.97, 95% CI 1.12-3.47). CONCLUSIONS Our findings suggest a need for tailored intervention targeting individuals at risk by gatekeepers to encourage individuals at risk to overcome feeling ashamed for seeking help and to cultivate an appropriate person to confide in.

Abstract
BACKGROUND When treating mentally ill criminal offenders, improving medication adherence is essential to achieving goals, such as long-term stabilization of symptoms and the prevention of recidivism. Most subjects who are treated under the Medical Treatment and Supervision Act have schizophrenia, which is considered a particularly difficult disorder for which to improve medication adherence. For such patients, we developed a Medication Discontinuation Program (MDP) that aims to improve medication adherence by discontinuing antipsychotic drugs and monitoring changes in psychiatric symptoms. We examined whether there was any utility for the MDP on a trial basis as well as whether it would be worthwhile to introduce the MDP to psychiatric programs. METHODS We conducted the MDP with an intervention group (n = 7) and compared Drug Attitude Inventory-30 (DAI-30) scores before and after implementation of the MDP. We also categorized 30 questions of the DAI-30 into three subscales: "awareness of the need for medication", "awareness of the effects of psychiatric drugs", and "impression of medication", and examined factors affecting improvement in medication adherence. RESULTS The total DAI-30 score significantly increased after completion of the MDP (P = 0.002). Significant elevations after completion of the MDP were also observed in the scores for three subscales of the DAI-30. CONCLUSIONS Our study suggests that the MDP has a possibility of improving medication adherence, and this program might have multidirectional and stimulatory effects on each factor related to the improvement of medication adherence.

Abstract
Engineered T-cell therapy using a CD19-specific chimeric antigen receptor (CD19-CAR) is a promising strategy for the treatment of advanced B-cell malignancies. Gene transfer of CARs to T-cells has widely relied on retroviral vectors, but transposon-based gene transfer has recently emerged as a suitable nonviral method to mediate stable transgene expression. The advantages of transposon vectors compared with viral vectors include their simplicity and cost-effectiveness. We used the Tol2 transposon system to stably transfer CD19-CAR into human T-cells. Normal human peripheral blood lymphocytes were co-nucleofected with the Tol2 transposon donor plasmid carrying CD19-CAR and the transposase expression plasmid and were selectively propagated on NIH3T3 cells expressing human CD19. Expanded CD3(+) T-cells with stable and high-level transgene expression (~95%) produced interferon-γ upon stimulation with CD19 and specifically lysed Raji cells, a CD19(+) human B-cell lymphoma cell line. Adoptive transfer of these T-cells suppressed tumor progression in Raji tumor-bearing Rag2(-/-)γc(-/-) immunodeficient mice compared with control mice. These results demonstrate that the Tol2 transposon system could be used to express CD19-CAR in genetically engineered T-cells for the treatment of refractory B-cell malignancies.

Abstract
PURPOSE The aim of this study was to construct a prediction model for posthepatectomy liver failure (PHLF), as defined by the International Study Group of Liver Surgery, and evaluate its accuracy in hepatocellular carcinoma (HCC) patients with cirrhosis or chronic hepatitis. METHODS A total of 277 consecutive hepatectomies for HCC between 2005 and 2013 were analyzed retrospectively. Multivariate logistic regression analysis was used to develop a predictive model for PHLF. The sensitivity, specificity, and area under the receiver operating characteristic (AUROC) curve were evaluated. The Hosmer-Lemeshow goodness-of-fit test was used to assess the model calibration. The constructed model was internally validated by k-fold cross-validation (k=5). RESULTS PHLF developed in 12.6% of hepatectomies. Multivariate analysis identified the following variables as predictors of PHLF: elevated preoperative serum bilirubin level, elevated preoperative international normalized ratio, and intraoperative packed red blood cell transfusion. The predictive model allowed discrimination between patients who developed PHLF and those who did not, with a sensitivity of 82.9%, specificity of 72.3%, and AUROC curve of 0.81 (95% CI, 0.74 to 0.89). The Hosmer-Lemeshow test indicated a good fit (P=0.545). The AUROC curve of the developed model was significantly greater than that of the model for end-stage liver disease (MELD) score (P=0.014), suggesting that the former model is better at predicting the PHLF than the latter one. CONCLUSIONS The developed model could be useful for predicting the occurrence of PHLF in HCC patients with underlying liver disease.

Abstract
OBJECTIVE We evaluated the percutaneous absorption of N,N-dimethylformamide (DMF) in DMF-exposed workers in the summer and winter by assessing their urinary levels of DMF metabolites. METHODS Breathing-zone concentrations of DMF and workers' urinary levels of N-methylformamide (NMF) and N-acetyl-S-(N-methylcarbamoyl)-cysteine (AMCC) were simultaneously measured in the summer and winter in 193 male workers wearing a respirator and chemical protective gloves. RESULTS The mean breathing-zone concentrations of DMF in both seasons were below the occupational exposure limit of 10 ppm. Although there was no significant seasonal difference in the breathing-zone concentrations of DMF, workers' urinary levels of NMF and AMCC were significantly higher in the summer than in the winter. Log-transformed urinary levels of the metabolites were significantly correlated with log-transformed breathing-zone concentrations of DMF in the summer, whereas no significant correlation between AMCC and DMF was found in the winter. The urinary levels of AMCC were dispersed more widely than those of NMF, suggesting that urinary AMCC reflected the cumulative exposure to DMF over a workweek. CONCLUSIONS Percutaneous absorption was the principal route of exposure to DMF for the respirator-wearing workers. Increased urinary levels of NMF and AMCC in the summer were attributed to increased percutaneous absorption of DMF resulting from the increased amount of water-soluble DMF absorbed by sweaty skin caused by the increased summertime room temperature and humidity.

Abstract
Cancer/testis (CT) antigens encoded by CT genes are immunogenic antigens, and the expression of CT gene is strictly restricted to only the testis among mature organs. Therefore, CT antigens are promising candidates for cancer immunotherapy. In a previous study, we identified a novel CT antigen, DNAJB8. DNAJB8 was found to be preferentially expressed in cancer stem-like cells (CSCs)/cancer-initiating cells (CICs), and it is thus a novel CSC antigen. In this study, we hypothesized that CT genes are preferentially expressed in CSCs/CICs rather than in non-CSCs/-CICs and we examined the expression of CT genes in CSCs/CICs. The expression of 74 CT genes was evaluated in side population (SP) cells (=CSC) and main population (MP) cells (=non-CSC) derived from LHK2 lung adenocarcinoma cells, SW480 colon adenocarcinoma cells and MCF7 breast adenocarcinoma cells by RT-PCR and real-time PCR. Eighteen genes (MAGEA2, MAGEA3, MAGEA4, MAGEA6, MAGEA12, MAGEB2, GAGE1, GAGE8, SPANXA1, SPANXB1, SPANXC, XAGE2, SPA17, BORIS, PLU-1, SGY-1, TEX15 and CT45A1) showed higher expression levels in SP cells than in MP cells, whereas 10 genes (BAGE1, BAGE2, BAGE4, BAGE5, XAGE1, LIP1, D40, HCA661, TDRD1 and TPTE) showed similar expression levels in SP cells and MP cells. Thus, considerable numbers of CT genes showed preferential expression in CSCs/CICs. We therefore propose a novel sub-category of CT genes in this report: cancer/testis/stem (CTS) genes.

Abstract
Although the natural history of H1N1 has been found to vary among patients, little is known about the factors that affect these variations. Infected patients with an extended infection history may shed virus longer and spread infection. To further clarify these variations, we evaluated the natural history of H1N1 infection in 324 university students using a descriptive epidemiological method and analyzed factors affecting the natural history of infection. The median times from infection to fever development and from fever development to cure were 2 days (range 0-8 days) and 5 days (range 1-12 days), respectively, and the median time not attending classes was 5 days (range, 1-13 days). Variations in H1N1 natural history were associated with both environmental and individual factors, including route of infection, grade, gender, epidemic period, respiratory and gastrointestinal symptoms and headache. Steps affecting these factors may help control variations in H1N1 natural history and may enhance infection control measures.

Abstract
BACKGROUND A worldwide outbreak of influenza A/H1N1 occurred in 2009. Little information is available regarding how the epidemic spread among young people, who composed the majority of individuals infected with this virus. We assessed the route of transmission of H1N1 among university students at Shinshu University, Japan. METHODS A total of 11,424 students were monitored between August 2009 and March 2010, and those who were diagnosed with confirmed, probable, or suspected H1N1 at a hospital or clinic were registered based on self-report to the university. Data including date of onset and suspected infection route were collected from the affected patients. RESULTS Of the 11,424 students, 1,016 (8.9%) were infected with H1N1. In most infected students, the suspected transmission route was associated with club activity, followed by close contact with friends and through lectures or laboratory work. After suspension of activity by clubs with more than 2 infected members, the number of infected individuals decreased. CONCLUSION H1N1 influenza spread in the university through specific routes, including club activity, close contact with friends, and lectures or laboratory work. During future outbreaks of influenza, interventions to reduce transmission through these routes may be effective infection control strategies in university students.

Abstract
We examined the effect of ambient temperature, air pressure and air pollutants on daily emergency admissions by identifying the cause of admission for each type of stroke and cardiovascular disease using generalized linear Poisson regression models allowing for overdispersion, and controlling for seasonal and inter-annual variations, days of the week and public holidays, levels of influenza and respiratory syncytial viruses. Every 1°C decrease in mean temperature was associated with an increase in the daily number of emergency admissions by 7.83% (95% CI 2.06-13.25) for acute coronary syndrome (ACS) and heart failure, by 35.57% (95% CI 15.59-59.02) for intracerebral haemorrhage (ICH) and by 11.71% (95% CI 4.1-19.89) for cerebral infarction. An increase of emergency admissions due to ICH (3.25% (95% CI 0.94-5.51)), heart failure (3.56% (95% CI 1.09-5.96)) was observed at every 1 hPa decrease in air pressure from the previous days. We found stronger detrimental effect of cold on stroke than cardiovascular disease.

Abstract
Cerebral ischaemia and intracranial haemorrhage are the major catastrophic events in the natural course of moyamoya disease. To prevent cerebral ischaemia extracranial/intracranial (EC/IC) bypass surgery has been done and the results of the surgery have been well documented. However, the mechanism(s) underlying intracranial bleeding and the therapeutic modalities used to prevent bleeding have not been well elucidated. We have retrospectively analysed 45 cases with intracranial haemorrhage among 192 patients with moyamoya disease treated and followed at our institute. Analysis of the initial patients with haemorrhage did not provide any new information other than the already reported theories about the origin and mechanism of bleeding. Analysis of 15 patients in whom haemorrhage occurred at least twice suggested that there were two different mechanisms of rebleeding. One group consisted of 7 cases, where haemorrhages were confined to the original bleeding site. In 3 of these 7 cases a small aneurysm was identified at the periphery of a moyamoya vessel. In 1 case a ruptured aneurysm was found on a major vessel. In 3 other cases no source of bleeding was identified. In all but 1 of these cases rebleeding occurred within 2 months after the initial ictus. The second group consisted of 8 cases where haemorrhage occurred repeatedly but at variable sites. In none of these cases were aneurysms or other vascular abnormalities identified to suggest the source of bleeding and in all of these cases rebleeding occurred more than 2 months after the initial ictus. In moyamoya disease intracranial bleeding may occur as a result of rupture of a tiny aneurysm situated at the periphery of the moyamoya vessels and which may have been destroyed after the initial bleeding. If the aneurysms persist after rupture they may re-rupture after a fairly short interval. In other cases bleeding occurs at different sites from the initial haemorrhage; these are considered to be a result of rupture of weak moyamoya vessels which are forced to act as collateral pathways and are under unusually increased haemodynamic stress. EC/IC bypass surgery is considered to be effective for the prevention of rebleeding in both groups of patients but in selected cases. Direct surgery is recommended when a peripheral aneurysm is found on a moyamoya vessel which has bled once.

Abstract
We retrospectively studied clinical characteristics of 368 patients with cerebral artery dissections who were diagnosed in 172 Japanese hospitals. Of these patients, 130 (35%) presented with subarachnoid hemorrhage, 217 (59%) with cerebral infarctions, and 21 (6%) with transient ischemic attacks. We analyzed 109 (84%) subarachnoid hemorrhage cases caused by vertebrobasilar artery dissection to evaluate conservative and surgical treatment from the viewpoint of postoperative rerupture and infarction.Subsequent ruptures were observed in 14% of the 21 cases with nonsurgical treatment. For the preventive purpose of rerupture, 88 patients received surgical interventions: 68 trappings, 13 proximal occlusions, 6 aneurysmal sac occlusions and 1 stenting. Rerupture was experienced in 33% of the aneurysmal sac occlusion patients while not occurring in the other three surgical interventions. In the group without vascular anastomosis, postoperative cerebral infarction was observed in 25% of the trapping, none of the proximal occlusion and 33% of the aneurysmal sac occlusion cases.In this study, aneurysmal sac occlusion treatments were more frequently complicated by rerupture or cerebral infarction postoperatively than the other treatment methods. It was difficult to determine which surgical treatment can achieve better surgical outcome among the proximal occlusion and trapping with or without vascular anastomosis.
