Abstract
Acrylamide is a probable carcinogen in humans. Few studies have assessed dietary acrylamide intake and the risk of pancreatic cancer; however, these studies are based on Western populations. Our purpose was to investigate the association of dietary acrylamide intake with the risk of pancreatic cancer utilizing data from the Japan Public Health Center-based Prospective Study. We evaluated the data of 89,729 participants aged 45-74 years, who replied to a questionnaire on past medical history and lifestyle habits from 1995-1998. Dietary acrylamide intake was estimated utilizing a validated food frequency questionnaire. We calculated the hazard ratios and 95% confidence intervals by using Cox proportional-hazards regression models. The average follow-up was 15.2 years, and 576 cases of pancreatic cancer were diagnosed. In the multivariate-adjusted model, an association between dietary acrylamide intake and pancreatic cancer risk was not demonstrated (hazard ratio for the highest vs. lowest quartile = 0.83, 95% confidence interval: 0.65-1.05, p for trend = 0.07). Furthermore, in the analyses stratified by sex, smoking status, coffee consumption, green tea consumption, alcohol consumption, and body mass index, no significant association was detected. Dietary acrylamide intake was not associated with the pancreatic cancer risk in Japanese individuals.

Abstract
Skin cancer is the most frequently diagnosed cancer in the fair-skinned population. In recent years, the incidence of nonmelanoma skin cancer (NMSC) has been increasing worldwide. However, there is no epidemiological study on skin cancer in the Asian population. A prospective cohort study including 140 420 participants was initiated in 1990 for cohort Ⅰ and 1993 for cohort Ⅱ at baseline survey from 11 public health center (PHC) areas. Of these participants, 284 NMSC cases were diagnosed during the follow-up period (through 2012 in the Osaka PHC area and 2013 in the other PHC areas). The Cox proportional hazards model was used to estimate hazard ratios and 95% confidence intervals (CI) for NMSC incidence according to occupational type, lifestyle factors (alcohol consumption, coffee consumption, smoking status, physical activity, and body mass index), and family history of cancer. Among men, compared with indoor workers, outdoor workers were associated with 2.18 (95% CI, 1.17-4.04) higher risk of squamous cell carcinoma (SCC) but not of basal cell carcinoma (BCC). Furthermore, men who have a family history of cancer had 1.99 (95% CI, 1.10-3.62) higher SCC risk. In women, we did not observe any association between occupational type and the risk of SCC (1.26; 95% CI, 0.68-2.32) or BCC (0.74; 95% CI, 0.42-1.28). In conclusion, men who are outdoor workers or have a family history of cancer had an increased risk of SCC.

Abstract
AIMS We aimed to reveal the effects of application of public-access automated external defibrillators (AEDs) and bystander-initiated cardiopulmonary resuscitation (CPR) on survival of paediatric patients with out-of-hospital cardiac arrest (OHCA) occurring on school campuses in Japan. METHODS AND RESULTS Data were obtained from a nationwide prospective observational study of paediatric OHCAs in school settings in Japan, termed Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS). Non-traumatic OHCA patients from elementary school, junior high school, and high school/technical college between April 2008 and December 2015 were enrolled. A multivariable logistic regression analysis was conducted to assess the effect of bystander interventions (i.e. public-access AED application and bystander-CPR) on 30-day survival with favourable neurological outcome. In total, 232 OHCA cases were analysed. The proportion of 30-day survival with favourable neurological outcome was significantly higher among the patients receiving both public-access AED application and bystander-CPR than those without any bystander intervention (50.9% vs. 20.0%, adjusted odds ratio 4.08, 95% confidence interval 1.25-13.31; P = 0.020). During the study period, the proportion of patients to whom public-access AEDs were applied increased significantly (from 61.9% in 2008 to 87.0% in 2015, P-for trend = 0.014). Accordingly, the proportion of 30-day survival with favourable neurological outcome improved significantly (from 38.1% in 2005 to 56.5% in 2015, P-for trend = 0.026). CONCLUSION The combination of public-access AED application and bystander-CPR increased the chance of survival approximately four-fold in schools. The nationwide efforts towards disseminating public-access defibrillation systems in school settings may reduce the risk of sudden cardiac death among school children.

Abstract
Little is known about the epidemiological characteristics of patients with coronavirus disease 2019 (COVID-19) in Japan. This is a retrospective observational study of COVID-19 patients; study was conducted from February 1 to May 31, 2020. We used publicly collected data on cases of COVID-19 confirmed by polymerase chain reaction (PCR) testing in Osaka Prefecture, Japan. We described the patient characteristics. The Cox proportional-hazards model was applied to evaluate the association between factors (sex, onset month, age group, city of residence) and mortality, and hazard ratios (HRs) with 95% confidence intervals were estimated. During the study period, 5.7% (1782/31,152) of individuals who underwent PCR testing for COVID-19 showed positive results. Among 244 patients with information on symptoms, the most common symptom was fever (76.6%), followed by cough (44.3%). Of the 1782 patients, 86 patients died. Compared with those aged 0–59 years, higher mortality was observed among those aged 60–69 years (HR: 12.02 [3.37–42.93]), 70–79 years (HR: 44.62 [15.16–131.30]), 80–89 years (HR: 68.38 [22.93–203.89]), and ≥90 years (HR: 144.71 [42.55–492.15]). In conclusion, in Osaka Prefecture, Japan, the most common symptom was fever, and older adults had higher mortality among COVID-19 patients.

Abstract
In 1955, an outbreak of arsenic poisoning caused by the ingestion of arsenic‐contaminated Morinaga Dry Milk occurred in western Japan. This study aimed to assess the mortality and cancer incidence risk among Japanese individuals who were poisoned during this time as infants. In total, 6223 survivors (mean age at enrollment, 27.5 y) who had ingested contaminated milk when they were aged ≤ 2 y participated in this study. Follow‐up was conducted from 1982 to 2018 (mean follow‐up duration, 30.3 y). Standardized mortality ratio (SMR) and standardized incidence ratio (SIR) were used to compare mortality and cancer incidence rates of subjects with the respective Japanese population rates, and 95% confidence intervals (95% CIs) of the SMR and SIR were also calculated. In total, 561 deaths and 524 new cancer cases were observed. A statistically significant increase in mortality rate was observed for all causes (SMR, 1.15; 1.01‐1.19), nervous system disease (2.83, 1.62‐4.19), respiratory disease (2.02, 1.37‐2.62), genitourinary system disease (2.25, 1.10‐3.73), and traffic accident (2.03, 1.14‐3.04). In contrast, a significant decrease in cancer incidence rate was observed for all cancers (SIR, 0.96; 0.84‐0.99), stomach cancer (0.77, 0.57‐0.92), colon cancer (0.63, 0.41‐0.85), rectum cancer (0.69, 0.43‐0.95), and breast cancer (0.72, 0.52‐0.89). Liver cancer showed a high mortality rate (SMR, 1.68; 1.06‐2.31). In this study, after the long‐term follow‐up we revealed overall and cause‐specific mortality and cancer incidence risk among survivors who ingested arsenic‐contaminated dry milk as infants.

Abstract
Acrylamide has been studied for its carcinogenicity in experimental animals, causing tumors at several organ sites, and has been considered probably carcinogenic to humans as well. Given the small number of epidemiological studies that have been conducted, it is still uncertain whether the consumption of acrylamide is associated with liver cancer. Therefore, we investigated a study to determine the possible relationship between acrylamide intake and the risk of developing liver cancer in the Japanese population. A total of 85,305 participants, from the Japan Public Health Center-based Prospective Study, who provided a validated food-frequency questionnaire were enrolled between 1995 and 1998. During a median of 16.0 years follow-up, 744 new liver cancer cases were identified. Compared to the lowest tertile of acrylamide consumption (<4.8 µg/day), the multivariate hazard ratio (HR) for the highest tertile (≥7.6 µg/day) was 0.79 (95% confidence interval [CI] = 0.65-0.95) for liver cancer using multivariable model 1, adjusted for smoking status, body mass index (BMI), physical activity, medical history, and alcohol consumption; whereas the inverse relationship disappeared after additionally adjusting for coffee consumption in multivariable model 2 with HR of 1.08 (95% CI = 0.87-1.34) for the highest tertile. The effect of dietary acrylamide intake on the risk of liver cancer was not observed in the Japanese population.

Abstract
In Japan, a study using population‐based cancer registry data from six prefectures revealed a difference in bladder cancer survival between men and women. However, the period of the study was limited to 1993‐2006. The recent introduction of immune checkpoint inhibitors, which have proved to be effective for the treatment for bladder cancer, has led to a rising demand for analysis of long‐term trends in net survival in order to accurately assess the effect of the new treatment. The aim of the present study was to examine long‐term trends in sex difference in bladder cancer net survival using large‐scale population‐based cancer registry data from Osaka, Japan (17,500 cases from 1975 to 2009). We also evaluated sex difference in bladder cancer survival after adjustment for stage, histologic type, and other prognostic factors. We showed the long‐term trend of five‐year net survival for each stage and found that women had poorer five‐year net survival than men for the whole study period. The risk of death from bladder cancer was higher among men than women even after adjusting for period at diagnosis, histologic type, stage, age group, and treatment (Excess hazard ratios: 1.17; 95% Confidence interval: 1.10‐1.25).

Abstract
Acrylamide, which forms in heat-treated foods with high carbohydrate content, is a probable human carcinogen. This study aimed to evaluate the association between dietary acrylamide intake and lung cancer using data from the Japan Public Health Center based Prospective Study. Our study included 85,303 participants who completed a food frequency questionnaire. Cox proportional hazards regression models were used to assess hazard ratios and 95% confidence intervals (CIs) after adjusting for confounders. After 14.3 years and 15.4 years of mean follow-up period, 1187 and 485 lung cancer cases were identified in men and women, respectively. The multivariable-adjusted hazard ratios of 10-µg/day increment in acrylamide intake were 1.01 (95% CI, 0.99–1.02) in men and 0.98 (95% CI, 0.95–1.02) in women. Compared with the lowest quartile of acrylamide intake, the hazard ratios for the highest quartile were 1.13 (95% CI, 0.95–1.33; p for trend = 0.12) in men and 1.03 (95% CI, 0.78–1.36; p for trend = 0.86) in women in the multivariable-adjusted model. Moreover, there was also no significant association observed in the stratified analysis for histological subtypes of lung cancer. This study demonstrated that dietary acrylamide intake was not associated with increased lung cancer risk in the Japanese population.

Abstract
There are limited real‐world data on the treatment practices, outcomes, and safety of chemoradiotherapy (CRT) alone in potential candidates for immune checkpoint inhibitors (ICI) for unresectable non‐small cell lung cancer (NSCLC). In this study, we analyzed the safety and efficacy of CRT in patients who underwent CRT and would satisfy the key eligibility criteria for maintenance therapy with durvalumab (eg, no progression after CRT) in real‐world settings (m‐sub) for unresectable Stage III NSCLC between 1 January 2013 and 31 December 2015 at 12 sites in Japan. The m‐sub comprised 214 patients with a median follow‐up of 31.6 months (range 1.9‐65.8 months). Median overall survival (OS) and progression‐free survival (PFS) from completing CRT were 36.4 months (95% confidence interval [CI] 28.1 months to not reached) and 9.5 months (95% CI 7.7‐11.7 months), respectively. Consolidation chemotherapy did not influence OS or PFS. Median PFS was 16.9 vs 9.1 months in patients with vs without epidermal growth factor receptor (EGFR) mutations, with PFS rates of ~20% at 3‐4 years. Pneumonitis was the most common adverse event (according to MedDRA version 21.0J), and about half of events were grade 1. Pneumonitis mostly occurred 10‐24 weeks after starting CRT, peaking at 18‐20 weeks. Esophagitis and dermatitis generally occurred from 0 to 4 weeks, peaking at 2‐4 weeks after starting CRT. Pericarditis was rare and occurred sporadically. In conclusion, the results of the m‐sub provide real‐world insight into the outcomes of CRT, and will be useful for future evaluations of ICI maintenance therapy after CRT.

Abstract
BACKGROUND Chemotherapy may be a cause of cancer-associated stroke, but whether it increases stroke risk remains uncertain. We investigated how chemotherapy affects stroke risk in cancer patients. METHODS Of 27,932 patients in a hospital-based cancer registry (which contains clinical data on all patients treated for cancer at Osaka University Hospital) screened between 2007 and 2015, medical records of 19,006 patients with complete data were investigated. A validated algorithm was used to identify stroke events within 2 years of cancer diagnosis. Patients were divided based on whether their initial treatment plan included chemotherapy. The association between chemotherapy and stroke was analyzed using the Kaplan-Meier method and stratified Cox regression. RESULTS Of 19,006 patients, 5,887 (31%) were in the chemotherapy group. Stroke occurred in 44 (0.75%) and 51 (0.39%) patients in the chemotherapy and nonchemotherapy group, respectively. Kaplan-Meier curve analysis showed that patients in the chemotherapy group had a higher stroke risk than those in the nonchemotherapy group (hazard ratio [HR] 1.84; 95% confidence interval [CI] 1.23-2.75). However, this difference was insignificant after adjustment for cancer status using inverse probability of treatment weighting with propensity scores (HR 1.20; 95% CI 0.76-1.91). Similarly, in the stratified Cox regression model, chemotherapy was not associated with stroke after adjustment for cancer status (HR 1.26; 95% CI 0.78-2.03). CONCLUSION In our study, the elevated stroke risk in cancer patients who received chemotherapy was presumably due to advanced cancer stage; chemotherapy was not associated with the increased risk of stroke.

Abstract
The effect of post-cardiac arrest care in children with out-of-hospital cardiac arrest (OHCA) has not been adequately established, and the long-term outcome after pediatric OHCA has not been sufficiently investigated. We describe here detailed in-hospital characteristics, actual management, and survival, including neurological status, 90 days after OHCA occurrence in children with OHCA transported to critical care medical centers (CCMCs).We analyzed the database of the Comprehensive Registry of Intensive Care for OHCA Survival (CRITICAL) study, which is a multicenter, prospective observational data registry designed to accumulate both pre- and in-hospital data on OHCA treatments. We enrolled all consecutive pediatric patients aged <18 years who had an OHCA and for whom resuscitation was attempted and who were transported to CCMCs between 2012 and 2016.A total of 263 pediatric patients with OHCA were enrolled. The average age of the patients was 6.3 years, 38.0% were aged < 1 year, and 60.8% were male. After hospital arrival, 4.9% of these pediatric patients received defibrillation; 1.9%, extracorporeal life support; 6.5%, target temperature management; and 88.2% adrenaline administration. The proportions of patients with 90-day survival and a pediatric cerebral performance category (PCPC) score of 1 or 2 were 6.1% and 1.9%, respectively. The proportion of patients with a PCPC score of 1 or 2 at 90 days after OHCA occurrence did not significantly improve during the study period.The proportion of pediatric patients with a 90-day PCPC score of 1 or 2 transported to CCMCs was extremely low, and no significant improvements were observed during the study period.

Abstract
BACKGROUND Due to concerns of carcinogenicity, it is necessary to assess long-term acrylamide exposure in individuals. Whether the available methods of estimating acrylamide intake can indicate long-term exposure remains unknown. We examined variations in the estimated dietary acrylamide intake of the Japanese population. METHODS The study included 240 participants aged 40-74 years who were a part of the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT). Twelve-day dietary records (DRs) were collected over a one-year period, and food frequency questionnaires (FFQs) were collected twice during the year. Dietary acrylamide intake was estimated from an acrylamide content database. Within-individual variations and between-individual variations were calculated using the random effects model. A linear regression analysis was performed to identify foods with large between-individual variations. RESULTS The ratios of within-individual variance to between-individual variation were 3.2 for men and 4.3 for women. Days of DRs required to estimate the usual individual intake within 20% of the true mean intake with 95% confidence were 60 days for men and 66 days for women. Coffee/cocoa, potato, and green tea contributed to between-individual variations, in that order, and seven foods contributed to 93% of the between-individual variation. CONCLUSIONS Estimating the acrylamide intake using DRs requires an extended data collection period to estimate the intragroup ranking and habitual intake of individuals. Long-term exposure assessments should be based on methods with less potential for measurement errors, such as the use of biomarkers.

Abstract
Introduction:
Chemotherapy may be a cause of cancer-associated stroke, but whether it increases stroke risk remains uncertain. We aimed to clarify the impact of chemotherapy on stroke risk in cancer patients.
Methods:
We investigated 27,932 patients enrolled in a hospital-based cancer registry at Osaka University Hospital between 2007 and 2015. The registry collects clinical data, including cancer status (site and stage), on all patients treated for cancer. Of them, 19,006 patients with complete data were included. A validated algorithm was used to identify stroke events within 2 years of cancer diagnosis. Patients were divided based on whether their initial treatment plan included chemotherapy. The association between chemotherapy and stroke was analyzed using the Kaplan-Meier method and stratified Cox regression.
Results:
Of the 19,006 patients, 5,887 (31%) patients were in the chemotherapy group. Non-targeted chemotherapy was used in 5,371 patients. Stroke occurred in 44 patients (0.75%) in the chemotherapy group and 51 patients (0.39%) in the no-chemotherapy group. Kaplan-Meier curve analysis showed that patients in the chemotherapy group had a higher stroke risk than patients in the no-chemotherapy group (HR 1.84; 95% CI 1.23-2.75; Figure [A]). However, this difference was insignificant after adjustment for cancer status using inverse probability of treatment weighting with propensity scores (HR 1.20; 95% CI 0.76-1.91; Figure [B]). Similarly, in the stratified Cox regression model, chemotherapy was not associated with stroke after adjustment for cancer status (HR 1.26; 95% CI 0.78-2.03). These findings were consistent with analysis wherein the effect of chemotherapy was treated as a time-dependent covariate (HR 1.02; 95% CI 0.55-1.88).
Conclusions:
In this population, the elevated stroke risk in cancer patients who received chemotherapy was presumably due to advanced cancer stage; chemotherapy was not associated with the increased risk of stroke.

Abstract
The incidence of breast cancer among Japanese women is substantially increasing. This study evaluated the effects of reproductive and lifestyle factors with respect to breast cancer overall and separately among pre- and postmenopausal women using data from the Three-Prefecture Cohort Study of Japan.A total of 33,410 women aged 40 to 79 years completed a self-administered questionnaire, which included items about menstrual and reproductive history and other lifestyle factors. The follow-up period was from 1984 to 1992 in Miyagi and 1985 to 2000 in Aichi Prefectures. We used Cox proportional hazards regression models to estimate hazards ratios (HRs) and 95% confidence intervals (CIs) after adjusting for confounding factors.After 9.8 mean years of follow-up, 287 cases of breast cancer were recorded. In the overall analysis, later menarche (≥16 years) and parity were significantly associated with a decreased risk of breast cancer, with HRs of 0.69 (95% CI 0.48-0.99) and 0.72 (95% CI 0.52-0.99), respectively. Further, there was a significant decline in the risk of breast cancer with increasing number of birth among parous women (P for trend = .010). On the contrary, a family history of breast cancer in the mother was significantly associated with an increased risk of breast cancer (HR 3.22, 95% CI 1.52-6.84). Analyses based on menopausal status at baseline indicated that height (≥160 cm) and weight (≥65 kg) were significantly associated with an increased risk of postmenopausal breast cancer, with HRs of 1.34 (95% CI 0.72-2.50) and 3.13 (95% CI 1.75-5.60), respectively. Risk associated with BMI significantly differs by menopausal status.Our findings suggest the important role of reproductive factors in the development of breast cancer in Japanese women; however, body mass index (BMI) may have different effects on breast cancer in Japanese women compared with western women.

Abstract
Aim To evaluate mortality among Japanese Olympic athletes compared with the general population and also evaluate their mortality based on total number of Olympics participation and intensity of sports disciplines. Methods Information on biography, vital status, date of birth, date of death and latest follow-up date on Japanese Olympians was retrieved from six online databases and compared. Standardised mortality ratio (SMR) was estimated according to observation periods and years from last participation in the Olympics. To further evaluate the association between mortality and total number of Olympics participation/intensity of sports disciplines within the study population, rate ratios (RRs) adjusted by sex, observation period and attained age group were estimated by a Poisson regression model. Results A total of 3381 Olympians were included in the analysis. The total person years was 94 076.82. The deaths of 153 (4.53%) Olympians were confirmed, and the overall SMR was 0.29 (95% CI, 0.25 to 0.34). SMRs categorised by years from last participation did not differ significantly. Higher mortality was observed among those who participated in the Olympics twice (RR: 1.52; 95% CI, 1.04 to 2.23) and three times or more (RR: 1.87; 95% CI, 1.08 to 3.25) compared with those who participated just once. Compared with combination of low static and low dynamic intensity category, higher mortality was observed in most combinations of middle-intensity or high-intensity categories. Conclusion Japanese Olympians lived longer than the general population. More frequent participation in the Olympics and higher intensity of sports disciplines were associated with higher mortality.

Abstract
BACKGROUND The effect of meat and fish consumption on cancer risk has been well studied in humans. However, studies related to biliary tract cancer (BTC) are scarce. METHODS We examined the association between meat and fish consumption and the risk of BTC in a population-based prospective cohort study in Japan. HRs and 95% confidence intervals (CI) were estimated using the Cox proportional hazard model. RESULTS During 1995 and 1999, 43,177 men and 49,323 women ages 45 to 74 years were enrolled and followed up for 607,757.0 person-years (men) and 728,820.3 person-years (women) until 2012, during which time 217 male and 162 female BTC cases were identified. Higher total meat consumption was significantly associated with a decreased BTC risk in men (HR for the highest vs. lowest quartiles = 0.66; 95% CI, 0.44-0.98; P trend = 0.011) but not in women. Similar association was observed with red meat, but no association was observed with poultry. Fish was not associated with BTC risk. We further analyzed each BTC subtype to confirm the observed association with BTC. However, significant association with each BTC subtype was not observed, although a trend of decreased extrahepatic bile duct cancer risk was observed. CONCLUSIONS BTC risk was lower among men who consumed more meat, particularly red meat, in Japan. IMPACT This is the first prospective study that evaluated the relationship between meat and BTC. This may provide important suggestions to elucidate the etiology of BTC.

Abstract
Purpose: This study aimed to clarify the experiences of caregivers desiring to refuse life-prolonging treatment for their elderly parents at the end of life. Methods: A semi-structured interview was performed for four family caregivers who wanted to refuse life-prolonging treatment suggested by the physicians. Results: In this study, four caregivers who refused life-prolonging treatment suggested by the physicians for their elderly parents completed semi-structured interviews. The obtained data were analyzed in relation to the theme “Experiences of caregivers who desire to refuse life-prolonging treatment for their elderly parents at the end of life.” As a result, 38 subcategories and 12 categories were extracted. Conclusions: Participants in this study initially had a negative view of life-prolonging treatment. However, they agonized over the decision when they received conflicting advice from the physicians. The participants indicated that physicians’ advice and attitudes complicated their decisions to reject life-prolonging treatment for their elderly parents.

Abstract
BACKGROUND Acrylamide has been classified as a probable human carcinogen based chiefly on laboratory evidence. However, the influence of dietary acrylamide intake on risk of esophageal, gastric, and colorectal cancer has not been extensively studied. We aimed to evaluate the association between dietary acrylamide intake and esophageal, gastric, and colorectal cancer using data from the Japan Public Health Center-based Prospective Study. METHODS Our study included 87,628 participants who completed a food-frequency questionnaire at enrollment in 1990 and 1993. We used Cox proportional hazards regression models to estimate hazards ratios and 95% confidence intervals (CI) after adjusting for confounding factors. RESULTS After 15.5, 15.3, and 15.3 mean years of follow-up for esophageal, gastric, and colorectal cancer, we identified and analyzed 391 esophageal, 2,218 gastric, and 2,470 colorectal cancer cases, respectively. Compared with the lowest quintile of acrylamide intake, the multivariate HR for the highest quintile was 0.86 (95% CI, 0.53-1.39; P trend = 0.814), 0.84 (95% CI, 0.69-1.01; P trend = 0.301), and 0.93 (95% CI, 0.79-1.08; P trend = 0.165) for esophageal, gastric, and colorectal cancer, respectively, in the multivariable-adjusted model. Furthermore, no significant associations were observed when the participants were stratified by cancer subsites. CONCLUSIONS In conclusion, this study demonstrated that dietary acrylamide intake was not associated with increased risk of esophageal, gastric, or colorectal cancer among the Japanese population. IMPACT It is the first time to assess the effect of dietary acrylamide intake on risk of digestive system cancer in Asian populations.

Abstract
Background:
It is commonly believed that a full moon affects human behavior or the occurrence and outcome of various diseases; thus, the occurrence of out-of-hospital cardiac arrest (OHCA) might increase during full moon nights. Methods and Results:
This nationwide, population-based observational study consecutively enrolled OHCA patients in Japan with attempted resuscitation between 2005 and 2016. The primary outcome measure was the occurrence of OHCA. Based on the double-control method, assuming Poisson sampling, we evaluated the average number of OHCA events that occurred on full moon nights compared with that which occurred on control nights, which included events that occurred on the same calendar days 1 week before and after the full moon nights. A total of 29,552 OHCA that occurred on 148 full moon nights and 58,707 OHCA that occurred on 296 control nights were eligible for analysis. The occurrence of OHCA did not differ between full moon and control nights (199.7 vs. 198.3 per night; relative risk [RR], 1.007; 95% CI: 0.993–1.021). On subgroup analysis, compared with control nights, the RR of OHCA occurrence were 1.013 (95% CI: 0.994–1.032, P=0.166) and 0.998 (95% CI: 0.977–1.020, P=0.866) for cardiac and non-cardiac origins, respectively. Conclusions:
In this population, there was no significant difference in OHCA occurrence between full moon and control nights.

Abstract
BACKGROUND Our objective was to assess the characteristics such as public-access defibrillation (PAD) by laypersons and the outcomes after pediatric out-of-hospital cardiac arrest by location in the PAD era. METHODS From a nationwide, prospective, population-based registry of out-of-hospital cardiac arrest patients in Japan, we enrolled consecutive pediatric patients aged ≤17 years before emergency medical service (EMS) arrival between 2013 and 2015. The primary outcome measure was 1-month survival, with favorable neurologic outcome defined as cerebral performance category 1 or 2. Factors associated with favorable neurologic outcome were assessed using multivariable logistic regression analysis. RESULTS Among 3991 eligible pediatric out-of-hospital cardiac arrests, the proportion of PAD was 0.2% (5/2888) at residence, 1.6% (2/125) in public areas, 0.9% (3/321) on streets/highways, 21.6% (11/51) at recreation/sports event areas, 46.1% (82/178) at education institutions, and 1.2% (5/428) in others. In the multivariable analysis, arrest witnessed by family members (adjusted odds ratio [AOR], 5.25; 95% confidence interval [CI], 3.22-8.58) and nonfamily members (AOR, 2.45; 95% CI, 1.26-4.77), first documented ventricular fibrillation (AOR, 12.29; 95% CI, 7.08-21.35), PAD (AOR, 2.63; 95% CI, 1.23-5.62), and earlier EMS response time (AOR for 1-min increment, 0.88; 95% CI, 0.81-0.94) were associated with improving outcome. As for locations, recreation/sports event areas (AOR, 3.43; 95% CI, 1.17-10.07) and education institutions (AOR, 3.03; 95% CI, 1.39-6.63) were also associated with favorable neurologic outcome. CONCLUSIONS In Japan, where public-access automated external defibrillators are well disseminated, characteristics such as PAD and outcomes for pediatric out-of-hospital cardiac arrest before EMS arrival differed substantially by location.

Abstract
IMPORTANCE Bystander interventions are a factor for improving survival of out-of-hospital cardiac arrest (OHCA), but it is hypothesized that girls and women experiencing OHCA may be less likely to receive bystander interventions than boys and men. OBJECTIVE To investigate sex disparities in receiving public-access automated external defibrillator (AED) pad application and bystander-initiated cardiopulmonary resuscitation (CPR) among students who experienced OHCA in school settings. DESIGN, SETTING, AND PARTICIPANTS This nationwide cohort study used the Stop and Prevent Cardiac Arrest, Injury, and Trauma in Schools (SPIRITS) database to link databases from 2 nationally representative registries-the Injury and Accident Mutual Aid Benefit System of the Japan Sport Council and the All-Japan Utstein Registry of the Fire and Disaster Management Agency. Students from elementary schools (ages 6-12 years), junior high schools (ages 12-15 years), high schools (ages 15-21 years), and technical colleges (ages 15-21 years) who experienced nontraumatic OHCA involving attempted resuscitation by emergency medical service personnel or bystanders in school settings from April 1, 2008, to December 31, 2015, were included. Data analysis was performed from January 5, 2019, to April 11, 2019. EXPOSURES Sex and school level. MAIN OUTCOMES AND MEASURES Application of public-access AED pads or initiation of CPR by a bystander. RESULTS A total of 232 students who experienced OHCA with nontraumatic causes in school settings (mean [SD] age, 14.5 [2.9] years; 175 [75.4%] male) were included. In multivariable analysis of the full cohort of students who experienced OHCA, female sex was associated with significantly lower odds of receiving public-access AED pad application compared with male sex (36 of 57 female students [63.2%] received AED pad application vs 141 of 175 male students [80.6%]; adjusted odds ratio [OR], 0.44; 95% CI, 0.20-0.97; P = .04). In the subgroup analysis of students who experienced OHCA in high schools or technical schools, female sex was associated with significantly lower odds of receiving public-access AED pad application compared with male sex (10 of 18 female students [55.6%] vs 84 of 101 male students [83.2%]; adjusted OR, 0.26; 95% CI, 0.08-0.87; P = .03). Among the full cohort, 48 of 57 female students (84.2%) and 151 of 175 male students (86.3%) received CPR from bystanders (adjusted OR, 0.81; 95% CI, 0.30-2.22), and there were no significant differences in receiving bystander-initiated CPR between sexes, irrespective of school level. CONCLUSIONS AND RELEVANCE Among students who experienced OHCA in schools in Japan, female sex was associated with lower odds of receiving public-access AED pad application compared with male sex.

Abstract
BACKGROUND Sudden cardiac death during exercise or sports is an important problem among young athletes and non-athletes. An understanding of the epidemiological features of sports-related out-of-hospital cardiac arrest (OHCA) among children is crucial for planning approaches for prevention and better outcomes of paediatric OHCAs. We assessed the characteristics and outcomes of sports-related OHCA among children at schools in Japan to prevent sports-related paediatric OHCA at schools. METHODS The Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS) is a nationwide, prospective, observational study linking databases of two nationally representative registries. Data on the characteristics and outcomes of sports-related paediatric OHCA at schools in Japan were obtained from these databases. RESULTS Between 2008 and 2015, 188 sports-related paediatric OHCAs due to presumed cardiac origin occurred. The greatest proportion of OHCA during or after sports was due to long-distance running (21.8%), followed by soccer/futsal (13.3%), basketball (12.2%), and baseball/rubber-ball baseball (11.2%). We also assessed the association between prehospital factors and one-month survival with favourable neurological outcome after sports-related OHCA. The proportions of ventricular fibrillation as the first documented rhythm, bystander cardiopulmonary resuscitation (CPR), and public-access defibrillation (PAD) were 87.8%, 87.2%, and 63.3%, respectively. Compared with the non-PAD group, the adjusted odds ratio (95% confidence interval) of the PAD group was 3.64 (1.78-7.45). CONCLUSIONS In Japan, 188 schoolchildren experienced OHCAs of cardiac origin occurring during or after sports activity at schools during the 8-year period. Increasing PAD is essential to enhance better neurological outcome after sports-related OHCA among students.

Abstract
BACKGROUND Coffee, which contains various bioactive compounds, is one of the most popular beverages. Further accumulation of evidence is needed, however, to confirm whether coffee consumption would be effective in preventing cardiovascular disease in the general Japanese population. Methods and Results: We evaluated the association between coffee consumption frequency (never, sometimes, 1-2 cups/day, 3-4 cups/day and ≥5 cups/day) and mortality from all causes, heart disease, and cerebrovascular disease, in 39,685 men and 43,124 women aged 40-79 years at baseline, in a 3-prefecture cohort study. The coffee consumption frequency was assessed on questionnaire. Cox proportional hazards regression modeling was used to assess the association between coffee consumption frequency and all-cause and cardiovascular disease mortality with adjustment for potential confounders. During 411,341 and 472,433 person-years in men and women, respectively, a total of 7,955 men and 5,725 women died. Coffee consumption frequency was inversely associated with all-cause mortality in both genders (P for trend<0.001). In addition, the risks of mortality from cerebrovascular disease in men (P for trend<0.001), and heart disease in women (P for trend=0.031) were inversely associated with coffee consumption. CONCLUSIONS In this Japanese population, coffee drinking has a preventive effect on all-cause and on cardiovascular mortality in men and/or women.

Abstract
Occupational asbestos exposure occurs in many workplaces and is a well‐known cause of mesothelioma and lung cancer. However, the association between nonoccupational asbestos exposure and those diseases is not clearly described. The aim of this study was to investigate cause‐specific mortality among the residents of Amagasaki, a city in Japan with many asbestos factories, and evaluate the potential excess mortality due to established and suspected asbestos‐related diseases. The study population consisted of 143 929 residents in Amagasaki City before 1975 until 2002, aged 40 years or older on January 1, 2002. Follow‐up was carried out from 2002 to 2015. Standardized mortality ratio (SMR) with its 95% confidence interval (CI) was calculated by sex, using the mortality rate of the Japanese population as reference. A total of 38 546 deaths (including 303 from mesothelioma and 2683 from lung cancer) were observed. The SMRs in the long‐term residents’ cohort were as follows: death due to all causes, 1.12 (95% CI, 1.10‐1.13) in men and 1.07 (95% CI, 1.06‐1.09) in women; lung cancer, 1.28 (95% CI, 1.23‐1.34) in men and 1.23 (95% CI, 1.14‐1.32) in women; and mesothelioma, 6.75 (95% CI, 5.83‐7.78) in men and 14.99 (95% CI, 12.34‐18.06) in women. These SMRs were significantly higher than expected. The increased SMR of mesothelioma suggests the impact of occupational asbestos exposure among men and nonoccupational asbestos exposure among women in the long‐term residents’ cohort. In addition, the high level of excess mortality from mesothelioma has persisted, despite the mixture of crocidolite and chrysotile no longer being used for three or four decades.

Abstract
Acrylamide, classified as a probable carcinogen to humans, forms during high- temperature cooking. Dietary exposure among the Japanese is unknown. To evaluate the validity of estimated acrylamide intake using a dietary record (DR) and the food frequency questionnaire (FFQ) in comparison with the duplicate diet method (DM) in a Japanese population. Design: A validation study was performed with 14 participants (age, 32-50 y; 11 women) from 11 households. Food samples were simultaneously collected for the DM and DR on the same day over 2 consecutive days. The FFQ was administered after collecting samples for the DM and DR. For the DM, dietary acrylamide was calculated from chemical analyses of each food. For the DR and FFQ, acrylamide intake for each food was calculated using the database of acrylamide contents of foods. Correlation coefficients were calculated using the Spearman rank method. Average acrylamide intake values calculated using the DM, DR, and FFQ were 0.106, 0.233, and 0.128 μg/kg body weight/d, respectively; these values showed a marginally positive correlation between the DM and DR (r=0.52), but a low correlation between the DM and FFQ (r=-0.011). For the DR, non-alcoholic drinks had the highest contribution, followed by confectionery and vegetables. For the DM, the contribution of confectionery was the highest, followed by vegetables and non-alcoholic drinks. In conclusion, the validity of acrylamide intake estimation using the DR was reasonably high when compared to the analytical value of the simultaneous DM. However, further improvement is required for estimating acrylamide intake using the FFQ.

Abstract
BACKGROUND To update the findings of relative risk associated with smoking for all-cause mortality and that for lung cancer by considering longitudinal changes in smoking status during follow-up. METHODS Data from the JPHC study of 98,747 middle-aged Japanese adults, which started in 1990-1993, were analyzed. The information on smoking status was obtained from three questionnaire surveys (baseline, the 5th year, and the 10th year after the start of follow-up). A Poisson regression model was used to investigate the impact of smoking on mortality from all causes and lung cancer using two approaches. Model 1 used information only from baseline, while model 2 used the updated smoking status from all three surveys. RESULTS During the 15-year follow-up, 10,702 all-cause deaths (including 870 lung cancer cases) were identified. We compared the results obtained from two models. The relative risks associated with former smokers versus never smokers were 1.42 (95% confidence interval [CI], 1.31-1.54) among men and 1.46 (95% CI, 1.23-1.73) among women for all-cause mortality and 2.98 (95% CI, 2.09-4.24) among men and 1.83 (95% CI, 0.92-3.64) among women for lung cancer mortality, as determined using model 2. All of these were higher than the relative risks obtained from model 1. In addition, former smokers who had quit smoking due to disease during follow-up had a higher mortality risk than continuous smokers did in this study. CONCLUSIONS The relative risks of all-cause mortality and mortality due to lung cancer among former smokers be higher than previously documented based on updated smoking status data from repeated surveys.

Abstract
BACKGROUND Acrylamide, a probable carcinogen to humans, forms during high temperature cooking. Dietary exposure to acrylamide among the Japanese population is unknown. We aimed to establish and validate a method to assess acrylamide exposure among the Japanese population using a food frequency questionnaire (FFQ) from the Japan Public Health Center-based prospective study. METHODS Validation studies for the FFQ were conducted in 1994 (Cohort I, n = 215) and 1996 (Cohort II, n = 350). The 28-day dietary records (DRs) were collected over 1 year. The FFQ was distributed before and after DR collection. Data for acrylamide exposure were based on reported measurements in Japan, and calculations considered the cooking process for specific vegetables in a home setting. Spearman's rank correlation and weighted kappa coefficients were calculated from energy-adjusted data. RESULTS Mean acrylamide intake levels estimated from DRs for Cohorts I and II were 6.78 (standard deviation [SD], 3.89) µg/day and 7.25 (SD, 3.33) µg/day, and corresponding levels estimated from the FFQ were 7.03 (SD, 4.30) µg/day and 7.14 (SD, 3.38) µg/day, respectively. Deattenuated correlation coefficients for men and women were 0.54 and 0.48 in Cohort I and 0.40 and 0.37 in Cohort II, respectively. Weighted kappa coefficients were over 0.80 in all cases. The main contributing food groups from DRs were beverages, confectioneries, vegetables, potatoes and starches, and cereals. CONCLUSIONS High kappa values validate the use of FFQ in epidemiological studies. The marked contribution of cooked vegetables indicates the importance of considering household cooking methods in assessing acrylamide intake levels in the Japanese population.

Abstract
A meta-analysis published in 2015 noted a marginally increased risk of endometrial and ovarian cancers in non-smoking women with dietary acrylamide intake, but only a few studies were included, and they were limited to Western countries. The aim of this study was to investigate the association between dietary acrylamide intake and endometrial or ovarian cancer risk in the Japan Public Health Center-based Prospective Study (JPHC Study). In this prospective cohort study, 47 185 participants aged 45-74 years at the follow-up starting point in the JPHC Study were enrolled. Dietary acrylamide intake was assessed using a validated food frequency questionnaire. Cox proportional hazards regression models were used to estimate hazard ratios (HR) and 95% confidence intervals (95%CI). In participants with endometrial and ovarian cancer, the average follow-up periods were 15.5 and 15.6 years, respectively, and 161 and 122 cases of endometrial and ovarian cancer were diagnosed, respectively. Energy-adjusted dietary acrylamide intake was negatively associated with endometrial cancer, but the association disappeared after adjusting for coffee consumption with an adjusted HR for the highest vs lowest tertile of 0.85 (95%CI: 0.54-1.33). No association was observed, however, for ovarian cancer (adjusted HR, 0.77; 95%CI: 0.49-1.23). Furthermore, after stratifying by smoking status, coffee consumption, alcohol consumption, body mass index, and menopause status, no association was observed. Dietary acrylamide intake was not associated with the risk of endometrial or ovarian cancer in Japanese women with a relatively lower dietary intake of acrylamide compared with Western populations.

Abstract
This study aimed to investigate the incidence, patient characteristics, and outcomes of out-of-hospital cardiac arrest (OHCA) occurring while in a motor vehicle in Osaka City, Japan (with a population of 2.6 million), from 2009 to 2015. The OHCA data used in this study were obtained from the population-based Utstein-style registry in Osaka City. Patients who had OHCA occurring while in a motor vehicle were included. The primary end point was 1-month survival with favorable neurologic outcome after OHCA. During the study period, 18,458 OHCAs were observed, and 264 of them (1.4%) occurred while on or in a motor vehicle (drivers, n = 179; nondrivers, n = 85). The overall incidence rate of OHCAs occurring while in a motor vehicle was 14.0 per million population per year (drivers, 9.5; nondrivers, 4.5). In the drivers with OHCAs, 78 (43.6%) and 101 (56.4%) cases were of medical origin and traffic injuries, respectively. Approximately half of OHCAs with a medical origin in drivers presumably occurred while driving (46.2%, 36 of 78). The overall proportion of 1-month survival with favorable neurologic outcome after OHCA was 6.4% (17 of 264). In the drivers, the proportion of OHCAs with a medical origin and because of traffic injuries were 11.5% (9 of 78) and 2.0% (2 of 101) (p = 0.008), respectively. In conclusion, although OHCAs occurring while in a motor vehicle represented a small subset of the overall OHCA burden, a relatively large number of cardiac arrests with a medical origin occurred in drivers.

Abstract
Background Smoking and alcohol are established risk factors for several types of cancer, but the effects on biliary cancers, comprising biliary tract cancer (BTC) and intrahepatic bile duct cancer (IHBDC), have been inconclusive. Methods In this population-based prospective cohort study in Japan, we investigated the association of smoking and alcohol consumption with the risks of BTC and its subtypes and IHBDC incidence in men and women. Furthermore, the association of smoking stratified by drinking status was investigated. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the Cox proportional hazard model. Results A total of 48,367 men and 54,776 women aged 40–69 years were enrolled from 1990 through 1994 and followed up for 846,417 person-years in men and 1,021,330 person-years in women until 2012, during which 246 BTC and 80 IHBDC male cases and 227 BTC and 60 IHBDC female cases were identified. In men, smoking was significantly associated with an increased risk of IHBDC (HR 2.25; 95% CI, 1.19–4.25 for current smokers with ≥30 pack-years compared with non-smokers), and the risk was enhanced among regular drinkers compared with non/occasional-drinkers (HR 3.48; 95% CI, 1.41–8.61). A non-significant increase of IHBDC risk associated with alcohol was observed. Neither smoking nor alcohol consumption was associated with BTC risk. In women, the association of smoking and alcohol consumption with IHBDC and BTC was unclear because current smokers and regular drinkers were very few. Conclusion Our findings suggest that smoking increases IHBDC risk in men, especially among regular drinkers.

Abstract
Greater height and body mass index (BMI) have been associated with an increased risk of thyroid cancer incidence in Western countries. However, few epidemiological studies have assessed the association between anthropometric factors, such as BMI, height, or weight, and thyroid cancer incidence in Asian populations. Using the population‐based Japan Public Health Center‐based prospective study database, we investigated the relationship between anthropometric factors and thyroid cancer incidence. Data on anthropometric factors were collected through a self‐administered questionnaire at baseline. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the Cox proportional hazards model, and the exposure level was categorized into quintiles. A total of 49,062 men and 53,661 women enrolled between 1990 and 1994 were included in our analyses, and 191 cases (37 in men and 154 in women) of thyroid cancer were identified, with 1,695,702 person‐years of follow‐up until 2010. Compared with the male group with height ≤160 cm, HRs of the male groups with height 165–168 cm and ≥169 cm were 3.92 (95% CI; 1.33–11.55, P = 0.013) and 4.24 (95% CI; 1.32–13.61, P = 0.015), respectively, and the HR per 5‐cm increase in height was 1.12 (95% CI 1.06–1.18, P < 0.001). In contrast, the association between anthropometric features and the risk of thyroid cancer did not significantly differ among women. In this population, an increase in risk for increased height was observed in men, but no associations between anthropometric indexes and thyroid cancer risk were observed in women.

Abstract
Acrylamide forms during cooking and is classified as a probable carcinogen in humans, mandating the need for epidemiological studies of dietary acrylamide and cancers. However, the risk of dietary acrylamide exposure to breast cancer in Japanese women has not been assessed. We investigated the association between dietary acrylamide intake and risk of breast cancer in the Japan Public Health Center-based Prospective Study. The present study included 48 910 women aged 45-74 years who responded to a 5-year follow-up survey questionnaire. Dietary acrylamide intake was assessed using a validated food frequency questionnaire. Cox proportional hazards regression models were used to estimate hazard ratios and 95% confidence intervals. During an average of 15.4 years of follow up, 792 breast cancers were diagnosed. Energy-adjusted dietary acrylamide intake was not associated with the risk of breast cancer (adjusted hazard ratio for highest versus lowest tertile = .95, 95% confidence intervals: 0.79-1.14, P-trend = .58). Further, no significant associations were observed when stratified analyses were conducted by smoking status, coffee consumption, alcohol consumption, body mass index, menopausal status, estrogen receptor status, and progesterone receptor status. In conclusion, dietary acrylamide intake was not associated with the risk of breast cancer in this population-based prospective cohort study of Japanese women.

Abstract
CONTEXT Childhood thyroid cancer is of great concern after the Fukushima nuclear power plant accident. Baseline analytical data on thyroid ultrasound examination (TUE) in children are important for future studies. OBJECTIVE We analyzed the age and sex distribution of findings from the TUEs of children and adolescents in the Fukushima Health Management Survey (FHMS). DESIGN, SETTING, AND PARTICIPANTS From October 2011 through March 2014, 294,905 participants aged 18 years or younger at the time of the earthquake voluntarily had TUEs in the first round of the FHMS. A secondary confirmatory examination was performed in 2032 subjects. Age- and sex-dependent prevalence and size of thyroid cysts, nodules, and cancers were analyzed. MAIN OUTCOME MEASURES Age, sex, and size distribution of findings were analyzed. RESULTS Thyroid cysts, nodules, and cytologically suspected cancers were detected in 68,009, 1415, and 38 male subjects and in 73,014, 2455, and 74 female subjects, respectively. There was an age-dependent increase in the detection rate of thyroid nodules and cancer, but that of cysts reached a peak at 11 to 12 years. Sex affected the prevalence of thyroid nodules and cancers after the onset of puberty, but only a small difference was exhibited in that of cysts. CONCLUSIONS The thyroid cancer detection rate in Fukushima was clarified, and the proportion of individuals with thyroid nodules and cysts varied substantially by age. The results of this study will contribute to future epidemiological research on nodular thyroid diseases in children and adolescents.

Abstract
BACKGROUND A better understanding of the epidemiology of pediatric out-of-hospital cardiac arrest (OHCA) occurring in school settings is important to establish an evidence-based strategy for prevention and better prognosis.Methods and Results:The Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS) is a nationwide prospective observational study linking databases from 2 nationally representative registries, the Injury and the Accident Mutual Aid Benefit System of The Japan Sport Council and the All-Japan Utstein Registry of the Fire and Disaster Management Agency. Using these databases, we described the detailed characteristics and outcomes of pediatric OHCAs that occurred in school settings in Japan between 2009 and 2014. During the 6-year study period, 295 OHCA cases were confirmed. Overall incidence rate was 0.4 per 100,000 students per year. The majority of OHCA cases had a cardiac origin (71%), occurred during exercise (65%), were witnessed by bystanders (70%), and received bystander-initiated cardiopulmonary resuscitation (73%). In approximately one-third of cases the student was defibrillated by public-access automated external defibrillator (38%). The proportion of patients with 1-month survival and a favorable neurological outcome was 34% among all OHCAs and 43% among OHCAs of cardiac origin. CONCLUSIONS In Japan, approximately 50 pediatric cases of OHCA consistently occur yearly in school settings. The majority of students received basic life support from bystanders, and patients with OHCA of cardiac origin had a relatively good prognosis.

Abstract
BACKGROUND We assessed whether the occurrence of out-of-hospital cardiac arrest (OHCA) with cardiac origin increased in the disaster areas during the 3-year period after the Great East Japan Earthquake (GEJE).Methods and Results:From the OHCA registry in Japan, yearly changes in occurrence after the GEJE were assessed by applying Poisson regression models. The risk ratio of the first year after the earthquake was significantly greater in both men and women, but the difference disappeared in the second and third years. CONCLUSIONS The GEJE significantly increased the occurrence of OHCA with cardiac origin in the first year after the earthquake.

Abstract
OBJECTIVES This study was performed to identify the prevalence, influence, and risk factors associated with chronic pain among Japanese industry workers. METHODS We investigated 2,544 participants working at a manufacturing company A, a manufacturing company B, and 16 branch shops of a retail chain company C. The participants responded to self-administered questionnaires related to pain. Furthermore, data obtained from the lifestyle interview sheet of an annual health screening examination and those obtained from the questionnaires were merged. We analyzed the association between lifestyles, psychosocial factors, and chronic pain. Age- and sex-adjusted odds ratios were calculated with a 95% confidence interval using the logistic regression model. RESULTS Of 2,544 participants, 1,914 (1,224 men and 690 women) completed the questionnaire, and the response rate was 75.2%. The prevalence of chronic pain over 3 months was 42.7% and that of chronic pain with work disability was 11.3%. A higher proportion of obesity, smoking habit, insomnia, psychological stress, depressive state, workaholic nature, low social support from supervisors and coworkers, high job demand, low job control, and job dissatisfaction was observed in workers with chronic pain than in workers without pain. CONCLUSIONS Several risk factors of chronic pain in Japanese industry workers were found. Obesity, smoking habits, sleep disorders, workplace environment, and mental state should be taken into account as risk factors associated with chronic pain issues and general occupational health.

Abstract
The preventive effect of coffee on cancer at different sites has been reported, but the effect on all‐sites cancer incidence has not been extensively investigated. We evaluated the association between frequency of coffee consumption and risk of all‐sites cancer incidence and mortality among 39 685 men and 43 124 women (age 40–79 years, at baseline), in the Three‐Prefecture Cohort Study. The association between frequency of coffee consumption and risk of all‐sites cancer incidence and mortality was assessed by a Cox proportional hazards regression model, adjusted for potential confounders. During 411 341 person‐years among men and 472 433 person‐years among women, a total of 4244 men and 2601 women developed cancer at different sites and a total of 3021 men and 1635 women died of cancer at different sites. We showed an inverse association between frequency of coffee consumption and all‐sites cancer incidence in both men and women. Comparing participants who consumed coffee with those who never drank coffee, the adjusted hazard ratios (95% confidential interval) for all‐sites cancer incidence was 0.74 (0.62–0.88) for coffee consumption of ≥5 cups/day in men (P for trend < 0.001) and 0.76 (0.58–1.02) in women (P for trend = 0.020). Coffee consumption frequency was inversely associated with mortality from all‐sites cancer. In this population, increasing coffee consumption resulted in a decreased risk of all‐sites cancer incidence and mortality.

Abstract
Oral mucositis (OM) is a serious side effect of cancer chemotherapy. The pathobiology of oral mucositis remains incompletely understood due to lack of appropriate models which recapitulate the human condition. Existing rodent models are intraperitoneal and require radiation, chemical or mechanical injury to the chemotherapy protocol to induce oral lesions. We aimed to develop an OM mouse model that is induced solely by chemotherapy and reproduces macroscopic, histopathologic and inflammatory characteristics of the human condition. Female C57BL/6 mice were given intravenous 5-Fluorouracil (5-FU) injections every 48 hours, for 2 weeks. A high daily dose of intraperitoneal administration was tested for comparison. Mice were monitored daily for weight loss. Epithelial histomorphometric analyses in tongue, esophageal and intestinal tissues were conducted coupled with assessment of apoptosis, cell proliferation, neutrophilic infiltration and the integrity of adherens junctions by immunohistochemistry. Neutropenia was assessed in peripheral blood and bone marrow. Tissues were analyzed for pro-inflammatory cytokines at the protein and mRNA levels. Daily intraperitoneal administration of 5-FU led to rapid weight loss and intestinal mucositis, but no oral inflammatory changes. Intravenous administration triggered atrophy of the oral and esophageal epithelium accompanied by reduction in cell proliferation and increased apoptosis. Coincidental with these changes were up-regulation of NF-κB, TNFα, IL-1β, GM-CSF, IL-6 and KC. Despite neutropenia, increased oral neutrophilic infiltration and reduced E-cadherin was observed in oroesophageal mucosae. We developed a novel experimental tool for future mechanistic studies on the pathogenesis of chemotherapy-induced OM.

Abstract
BACKGROUND The patient characteristics, pre-hospital interventions, and outcomes of out-of-hospital cardiac arrests (OHCA) occurring during exercise, have not been sufficiently investigated among the general population. METHODS OHCA data from 2009 to 2015 were obtained from the population-based OHCA registry in Osaka City, Japan. Patients who suffered OHCA, which occurred during exercise before the arrival of emergency medical service personnel, were included. The primary endpoint was one-month survival with a favourable neurological outcome after OHCA, defined using the Glasgow-Pittsburgh cerebral performance category scale 1 or 2. RESULTS During the 7-year study period, 16,278 OHCAs were observed, and 52 (0.3%) occurred during exercise (male, n=41 [79%]; median age, 62 years). These incidents occurred mainly during running activities (n=14), followed by swimming (n=8), dance/social dance (n=6), tennis (n=4), and weight training (n=3). Within these exercise-related OHCAs, 47 (90%) were of cardiac origin, 45 (87%) were bystander-witnessed cardiac arrests, 49 (94%) received bystander-initiated cardiopulmonary resuscitation, and 30 (57%) received public-access defibrillation (PAD). Overall, 56% (29/52) had one-month survival with a favourable neurological outcome after OHCA, which was significantly higher among OHCAs of cardiac origin with PAD (77%, 23/30) than among those of cardiac origin without PAD (35%, 6/17) and among those of non-cardiac origin (0%, 0/5) (p<0.001). CONCLUSION In Osaka, OHCAs during exercise represented a small subset of the overall OHCA burden, but occurred during a wide variety of exercise activities. Patients with OHCA of cardiac origin had a good prognosis, and PAD played an important role in improving patient outcomes.

Abstract
Background: Cruciferous vegetables, a rich source of isothiocyanates, have been reported to lower the risk of several types of cancer, including lung cancer. However, evidence from prospective observations of populations with a relatively high intake of cruciferous vegetables is sparse.Objective: We investigated the association between cruciferous vegetable intake and lung cancer risk in a large-scale population-based prospective study in Japan.Methods: We studied 82,330 participants (38,663 men; 43,667 women) aged 45-74 y without a past history of cancer. Participants were asked to respond to a validated questionnaire that included 138 food items. The association between cruciferous vegetable intake and lung cancer incidence was assessed with the use of Cox proportional hazard regression analysis to estimate HRs and 95% CIs (with adjustments for potential confounding factors).Results: After 14.9 y of follow-up, a total of 1499 participants (1087 men; 412 women) were diagnosed with lung cancer. After deleting early-diagnosed cancer and adjusting for confounding factors, we observed a nonsignificant inverse trend between cruciferous vegetable intake and lung cancer risk in men in the highest compared with the lowest quartiles (multivariate HR: 0.85; 95% CI: 0.69, 1.06; P-trend = 0.13). Stratified analysis by smoking status revealed a significant inverse association between cruciferous vegetable intake and lung cancer risk among those who were never smokers and those who were past smokers after deleting lung cancer cases in the first 3 y of follow-up [multivariate HR for never smokers: 0.49 (95% CI: 0.27, 0.87; P-trend = 0.04); multivariate HR for past smokers: 0.59 (95% CI: 0.35, 0.99; P-trend = 0.10)]. No association was noted in men who were current smokers and women who were never smokers.Conclusion: This study suggests that cruciferous vegetable intake may be associated with a reduction in lung cancer risk among men who are currently nonsmokers.

Abstract
Background We reutilized the existing Three-Prefecture Cohort to evaluate the relationship between lifestyle factors and the incidence or mortality from non-communicable diseases. Methods This study was a prospective population-based observation conducted from the 1980s to 2000 in three prefectures (Miyagi, Aichi, and Osaka) in Japan. The study subjects were residents aged ≥40 years who received a questionnaire. The follow-up period was 15 years from the baseline survey in each study area. A self-administered questionnaire, which included items on participants' demographic factors and lifestyle characteristics, was administered. Vital status and date of death were collected from residence certificates by the local government, and cause of death was identified using vital statistics. Cancer incidence and the date of diagnosis were collected from local cancer registry data. Results A total of 46,421 men and 54,189 women were eligible for our analysis. The person-years of follow-up for cancer incidence were 464,664 and 567,271 for men and women, respectively, and those for death were 527,940 and 648,601 for men and women, respectively. There were 8479 cancer incidences (5106 men and 3373 women) and 20,240 total deaths (11,156 men and 9084 women). The stomach was the most common cancer incidence site for both men (25.6%) and women (18.6%). The leading cause of death was cancer among men (35.0%) and cardiovascular disease among women (41.0%). Conclusions The Three-Prefecture Cohort Study enabled us to reveal the association of multiphasic lifestyle factors with cancer incidence and mortality. The study will also allow us to conduct a pooled analysis in combination with other large-scale cohorts. The Three-Prefecture Cohort had about 100,000 participants in urban and rural areas. This cohort collected detailed information on participants' lifestyles. This cohort had data on participants' cancer incidence and mortality.

Abstract
Tissues surrounding dental implants and teeth develop clinical inflammation in response to microbial stimuli. However, the literature suggests that differences exist in the microbial insult and inflammatory responses leading to gingivitis and peri-implant mucositis. In this pilot study, the authors use for the first time a systems biology approach to comprehensively evaluate clinical parameters, selected inflammatory markers, and the microbiome of subject-matched tooth and implant sites during native inflammation and in response to experimental plaque accumulation. Fifteen subjects with 2 posterior implants and corresponding contralateral teeth were examined at enrollment; at day 0, after reinstitution of gingival/mucosal health; at days 7, 14, and 21, during stent-mediated oral hygiene (OH) abstention; and at day 42, after resumption of OH. The subgingival microbiome was evaluated via 16S rRNA gene sequencing and 8 selected inflammatory markers measured in crevicular fluid. Comparison of teeth and implants via general linear models based on orthogonal polynomials showed similar responses in clinical parameters, inflammatory mediators, and proportions of individual microbial taxa during OH abstention. Implants, however, accumulated less plaque and underwent more heterogeneous shifts in microbiome structure. A multilevel, within-group, sparse partial least squares analysis of covariation of microbial, inflammatory, and clinical parameters throughout all study visits found inflammation around teeth and implants positively correlated with IL-1 alpha and IL-1 beta and with the proportions of Selenomonas, Prevotella, and 5 species-level phylotypes. Gingivitis, however, showed a stronger positive correlation with lactoferrin and IL-1ra and a stronger negative correlation with Rothia. Peri-implant mucositis, on the contrary, correlated positively with certain microbial taxa not associated with gingivitis by a previous study or the current one. In summary, differences existed between implants and tooth sites in microbiome evolution during OH abstention and in the correlation of specific inflammatory mediators and microbial taxa with clinical inflammation. Common biological features, however, were also identified for gingivitis and mucositis.
