RESUMO

BACKGROUND: It has been reported that psychological stress affects bone metabolism and increases the risk of fracture. However, the relationship between bone fractures and post-traumatic stress disorder (PTSD) is unclear. This study aimed to evaluate the effects of disaster-induced PTSD symptoms on fracture risk in older adults. METHODS: This study evaluated responses from 17,474 individuals aged ≥ 65 years without a history of fractures during the Great East Japan Earthquake who answered the Mental Health and Lifestyle Survey component of the Fukushima Health Management Survey conducted in 2011. The obtained data could determine the presence or absence of fractures until 2016. Age, sex, physical factors, social factors, psychological factors, and lifestyle factors were subsequently analyzed. Survival analysis was then performed to determine the relationship between the fractures and each factor. Thereafter, univariate and multivariate Cox proportional hazard models were constructed to identify fracture risk factors. RESULTS: In total, 2,097 (12.0%) fractures were observed throughout the follow-up period. Accordingly, univariate and multivariate Cox proportional hazard models showed that PTSD symptoms (total PTSD checklists scoring ≥ 44) [hazard ratio (HR): 1.26; 95% confidence interval (CI): 1.10-1.44; P = 0.001], history of cancer (HR: 1.49; 95% CI: 1.24-1.79; P < 0.001), history of stroke (HR: 1.25; 95% CI: 1.03-1.52; P = 0.023), history of heart disease (HR: 1.30; 95% CI: 1.13-1.50; P < 0.001), history of diabetes (HR: 1.23; 95% CI: 1.09-1.39; P < 0.001), current smoking (HR: 1.29; 95% CI: 1.02-1.63; P = 0.036), and high dissatisfaction with sleep or no sleep at all (HR: 1.33; 95% CI: 1.02-1.74; P = 0.035) promoted a significant increase in fracture risk independent of age and sex. CONCLUSIONS: The present study indicates that disaster-induced PTSD symptoms and insomnia contribute to increased fracture risk among older adults residing in evacuation areas within the Fukushima Prefecture.

RESUMO

OBJECTIVE: Several studies have reported that laughter is associated with health benefits. In addition, social interactions, such as social relationships, social participation and so forth, have shown the association with not only health but also individual emotion. In this study, we conducted a cross-sectional study to examine the association between variety of social interactions and the frequency of laughter. DESIGN: Cross-sectional study. SETTING: Sampled from 30 municipalities in Japan. PARTICIPANTS: Non-disabled Japanese men (n=11 439) and women (n=13 159) aged ≥65 years using data from the Japan Gerontological Evaluation Study, which was conducted during October to December in 2013. PRIMARY OUTCOME MEASURES: Laughing almost every day by self-reported questionnaire. RESULTS: Poisson regression analysis with robust error variance was used to calculate prevalence ratios (PRs) for laughing almost every day according to each social relationship and its potential community-level environmental determinants. The prevalence of laughing almost every day tended to increase with increased variety in each social interaction after adjusting, instrumental activities of daily living, number of living together, working status, depression, self-reported economic status and residence year. Among men and women, multivariate-adjusted PRs (95% CIs) by comparing participants with the highest and lowest categories were 1.18 (1.04 to 1.35) and 1.16 (1.04 to 1.29) in positive life events; 1.26 (1.10 to 1.45) and 1.09 (0.96 to 1.24) in perceived positive changes in the area; 1.15 (1.04 to 1.28) and 1.17 (1.07 to 1.28) in social participations; 2.23 (1.57 to 3.16) and 1.47 (1.02 to 2.12) in social relationships and 1.25 (1.08 to 1.45) and 1.29 (1.15 to 1.45) in positive built environments. These associations were also preserved after the restriction of participants who were not in depression. CONCLUSIONS: This study shows that a greater variety of each social relationships and the potential community-level environmental determinants are associated with higher frequencies of laughter in Japan.

RESUMO

PURPOSE: The Controlling Nutritional Status (CONUT) Score, originally developed as a nutritional screening tool, is a cumulative score calculated from the serum albumin level, total cholesterol level, and total lymphocyte count. Previous studies have demonstrated that the score has significant prognostic value in various malignancies. We investigated the relationship between the CONUT score and long-term survival in obstructive colorectal cancer (OCRC) patients who underwent self-expandable metallic colonic stent placement and subsequently received curative surgery. METHODS: We retrospectively analyzed 57 pathological stage II and III OCRC patients between 2013 and 2019. The associations between the preoperative CONUT score and clinicopathological factors and patient survival were evaluated. RESULTS: A receiver operating characteristic curve analysis revealed that the optimal cut-off value for the CONUT score was 7. A CONUT score of ≥ 7 was significantly associated with elevated CA19-9 level (p = 0.03). Multivariate analyses revealed that a CONUT score of ≥ 7 was independently associated with cancer-specific survival (hazard ratio [HR] = 10.2, 95% confidence interval [CI] 1.2-85.9, p = 0.03) and disease-free survival (HR = 7.1, 95% CI 2.3-21.7, p = 0.0006). CONCLUSION: The results demonstrated that the CONUT score was a potent prognostic indicator. Evaluating the CONUT score might result in more precise patient assessment and tailored treatment.

RESUMO

To examine the associations of salt perception with salt intake and blood pressure levels in general populations, we performed a cross-sectional study in two communities where salt intake level is different, Akita and Osaka in Japan. Taste perception (detection for certain taste and recognition for salt taste) was determined using a Na-impregnated test strip for 1024 Akita and 1199 Osaka adults aged 30-74 years. The proportions of detection for 0·1 % salt were 61, 62, 79, and 79 % in Akita men, Osaka men, Akita women and Osaka women, respectively. The corresponding proportions of not recognising of 1·6 % salt taste (>1·6 %) were 34, 30, 16 and 21 %. Detection threshold was higher in Akita than in Osaka for women aged 60-74 years, and recognition threshold was lower in Akita than in Osaka for women aged 30-59 and 60-74 years. The high detection (≥0·4 %) and recognition (>1·6 %) thresholds of salt taste were associated with higher salt intake scores for Akita men aged 30-59 years, whose detection and recognition thresholds tended be positively associated with systolic and diastolic blood pressures (SBP and DBP) after adjustment for potential confounders. Among Akita elderly men, detection threshold tended to be positively associated with SBP and DBP, while among Akita middle-aged women, recognition threshold was associated with SBP. In conclusion, the high thresholds of salt perception were inversely associated with salt intake for Akita middle-aged men and with blood pressure levels for Akita middle-aged and elderly men and middle-aged women.

RESUMO

Background/Aims: The aim of this study was to evaluate the safety of sedation with propofol as an alternative to benzodiazepine drugs in outpatient endoscopy. Methods: In this prospective study, examinees who underwent outpatient endoscopy under propofol sedation and submitted a nextday questionnaire with providing informed consent were evaluated. Periprocedural acute responses, late adverse events within 24 hours, and examinee satisfaction were evaluated. Results: Among the 4,122 patients who received propofol in the 17,978 outpatient-based endoscopic examinations performed between November 2016 and March 2018, 2,305 eligible examinees (esophagogastroduodenoscopy for 1,340, endoscopic ultrasonography for 945, and total colonoscopy for 20) were enrolled, and their responses to a questionnaire were analyzed. The mean propofol dose was 69.6±24.4 mg (range, 20-200 mg). Diazepam, midazolam, and/or pentazocine in combination with propofol was administered to 146 examinees. Mild oxygen desaturation was observed in 59 examinees (2.6%); and mild bradycardia, in 2 (0.09%). Other severe reactions or late events did not occur. After eliminating 181 invalid responses, 97.7% (2,065/2,124) of the patients desired propofol sedation in future examinations. Conclusions: Propofol sedation was found to be safe-without severe adverse events or accidents-for outpatient endoscopy on the basis of the patients' next-day self-evaluation. Given the high satisfaction level, propofol sedation might be an ideal tool for painless endoscopic screening.

RESUMO

INTRODUCTION: Admission hyperglycemia is an indicator of poor functional prognosis in acute stroke, but investigations of its prevalence and effects on the outcomes of acute large vessel occlusion in real-world, large-scale studies are limited, especially in Asian population. OBJECTIVE: We aimed to elucidate the relationship between admission hyperglycemia and outcomes in a prospective multicenter registry in Japan. METHODS: We analyzed data from the Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism (RESCUE) Japan Registry 2, which was a prospective, multicenter registry that enrolled patients from 46 centers in Japan. Admission hyperglycemia was defined as blood glucose level >140 mg/dL. The relationships between clinical outcomes and admission hyperglycemia were analyzed in all 1,932 assessable patients. A favorable functional outcome, defined as a modified Rankin Scale score of 0-2 at day 90, as well as mortality within 90 days and symptomatic intracranial hemorrhage (SICH) within 72 h, was analyzed. We performed subgroup analyses of the adjusted variables to investigate the association between hyperglycemia and favorable outcome in relation to each variable. RESULTS: Admission hyperglycemia was present in 687 (35.6%) of the assessable patients and in 420 (26.9%) of the 1,561 patients without diabetes. A favorable outcome was significantly less frequent in the hyperglycemia group than in the no-hyperglycemia group (33.2% vs. 47.6%, adjusted odds ratio [OR]: 0.60, 95% confidence interval [CI]: 0.47-0.76). The mortality rates were 12.8% and 6.8% in the hyperglycemia and no-hyperglycemia groups, respectively. The incidence of SICH within 72 h was higher in the hyperglycemia group than in the no-hyperglycemia group (4.4% vs. 1.9%, adjusted OR: 2.54, 95% CI: 1.36-4.82). Hyperglycemia was associated with unfavorable outcomes in almost all subgroups. CONCLUSIONS: Admission hyperglycemia in Japanese patients with large vessel occlusion stroke is associated with an unfavorable functional outcome at 90 days, mortality within 90 days, and the occurrence of SICH within 72 h.

RESUMO

BACKGROUND: Few studies have investigated the association between serum albumin levels and the risk of stroke subtypes among the general Japanese population.Methods and Results:In this study, 5,071 men and 7,969 women aged 40-74 years, initially free from stroke, coronary artery disease, and kidney and hepatic failure, and residing in 4 Japanese communities completed a baseline risk factor survey between 1985 and 1994. During the 24-year follow-up, 528 men and 553 women experienced stroke. In the entire study cohort, multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) of total stroke, ischemic stroke, and intracerebral hemorrhage for the lowest vs. highest quartiles of serum albumin were 1.45 (1.18-1.77), 1.52 (1.17-1.97), and 1.57 (1.04-2.37), respectively. In men, multivariable HRs (95% CIs) for total stroke, ischemic stroke, and intracerebral hemorrhage in the lowest vs. highest serum albumin quartile were 1.44 (1.07-1.92), 1.48 (1.03-2.11) and 1.71 (0.92-3.18), respectively, whereas in women they were 1.50 (1.13-1.99), 1.63 (1.11-2.39), and 1.56 (0.89-2.74), respectively. Similar inverse associations were observed for each of the ischemic stroke subtypes, but not for subarachnoid hemorrhage. CONCLUSIONS: Low serum albumin levels were associated with an increased risk of total stroke, ischemic stroke, ischemic stroke subtypes, and intracerebral hemorrhage.

RESUMO

Evidence regarding the effect of psychological factors and evacuation on cardiovascular disease occurrence after large-scale disasters is limited. This prospective study followed up a total of 37,810 Japanese men and women aged 30-89 years from the Fukushima Prefecture with no history of stroke or heart disease at baseline (2012), until 2017. This period included 3000 cardiovascular events recorded through questionnaires and death certificates. The participants' psychological distress, trauma reaction, and evacuation status were defined, and divided into four groups based on combinations of psychological factors and evacuation status. We calculated the hazard ratios and 95% confidence intervals for only psychological, only evacuation, or both of them compared with neither using Cox proportional hazard models. Psychological factors along with evacuation resulted in approximately 5% to 25% higher magnitude of stroke and heart disease risk than psychological factors only among men. Compared to neither, the multivariable hazard ratios of those with both psychological distress and evacuation were 1.75 for stroke and 1.49 for heart disease, and those of both trauma reaction and evacuation were 2.01 and 1.57, respectively, among men. Evacuation combined with psychological factors increased the risk of stroke and heart disease risks especially in men after the Great East Japan Earthquake.

RESUMO

Increase in left ventricular (LV) mass develops as a compensatory mechanism against pressure overload in aortic valve stenosis. However, long-standing LV geometrical changes are related to poor prognosis. The LV geometrical change occurs after transcatheter aortic valve replacement (TAVR). The present study aimed to investigate the relationship between improvement in valvuloarterial impedance (Zva) and change in LV mass index (LVMI) and the ratio of LVMI to LV end-diastolic volume index (LVMI/LVEDVI). We compared these relationships to that between Zva and mean pressure gradient (MPG). Baseline and follow-up transthoracic echocardiograms of 301 patients who underwent TAVR from November 2011 to December 2015 were reviewed. Spearman correlation coefficient (ρ) was used to compare ΔLVMI and ΔLVMI/LVEDVI with Zva or MPG. The correlation between ΔZva and ΔLVMI (ρ = 0.47, p < 0.001) was superior to that between ΔMPG and ΔLVMI (ρ = 0.15, p = 0.009) (p for comparison < 0.001). The correlation between ΔZva and ΔLVMI/LVEDVI was statistically significant (ρ = 0.54, p < 0.001); in contrast, that of ΔMPG and ΔLVMI/LVEDVI was not. The improvement in Zva after TAVR was more closely related to LVMI and LVMI/LVEDVI reduction than MPG reduction.

RESUMO

Introduction Traumatic experiences and disordered sleep are strongly associated with drinking problems. We examined the effects of experiencing the Great East Japan Earthquake and subsequent nuclear power plant accident, and of sleep problems, on behavioral changes observed in non-drinkers.Methods This study examined cross-sectional data from the Mental Health and Lifestyle Survey conducted among residents in restricted areas of Fukushima in 2012. Participants were 21,454 evacuees aged 20 years or older at the time of disaster. People who did not drink before the disaster but became drinkers afterwards were compared with the rest of the cohort. We analyzed the association between behavioral changes in non-drinkers and potentially predictive variables, using logistic regression.Results The behavioral change of non-drinkers becoming drinkers (n=2,148) was significantly related to being male (OR=1.93, 95% CI:1.74-2.15), being younger (21-49 yrs, OR=1.85, 95% CI: 1.60-2.13), having less educational attainment (up to high school graduate, OR=1.21, 95% CI:1.09-1.35), smoking (OR=1.22, 95% CI:1.08-1.38), losing family or relatives (OR=1.21, 95% CI:1.07-1.37), change in employment (OR=1.19, 95% CI:1.07-1.32), having severe sleep problems as measured by a Japanese version of the Athens Insomnia Scale (3-8, OR=1.45, 95% CI:1.30-1.62), and severity of traumatic symptoms as measured by the PTSD Checklist Stressor-Specific (PCL-S) score (<44, OR=1.33, 95% CI:1.17-1.51).Conclusion Having sleep problems and having more severe traumatic symptoms are significantly related to non-drinkers becoming drinkers.

RESUMO

BACKGROUND/AIMS: For early gastric cancer (EGC) treated using endoscopic submucosal dissection (ESD) with poor curability defined by the Japanese Guidelines (non-curative EGC, N-EGC), additional gastrectomy has been recommended. However, N-EGC patients without additional gastrectomy often die of other diseases within a relatively short interval after ESD. It has been unclear whether additional gastrectomy is beneficial or not for such patients. The aim of this study was to clarify predictors for short-term survival of N-EGC patients without additional gastrectomy after ESD. METHODS: One hundred six N-EGC patients without additional gastrectomy were included in this study. Factors related to short-term survival, defined as death within 3 years after ESD, were evaluated using uni- and multivariate analyses by comparing patients with and without short-term survival (Groups S and C, respectively). RESULTS: During the mean follow-up period of 89 months, 39 patients died (14 patients died within 3 years, being Group S). The cause of death was gastric cancer for only 1 patient in the Group C. The 3- and 5-year overall survival rates were 86.8 and 81.8%, respectively, and the 3- and 5-years disease-specific survival rates were 100 and 98.9%, respectively. Univariate analyses showed that short-term survival was statistically associated with elevated morphology, high-risk status for lymph node metastases as defined by the eCura system, severe comorbidity (Charlson Comorbidity Index [CCI] ≥3), low level of activity in daily living (being unable to go out by oneself), habitation (a nursing home), and several poor nutritional prognostic indices (neutrophil to lymphocyte ratio ≥2.5, geriatric nutritional risk index <92, C-reactive protein ≥1.0). In the multivariate analysis, a high CCI (≥3) was the independent predictor for short-term survival after ESD (odds ratio, 8.1; 95% confidence interval, 1.53-43.0; p = 0.014). CONCLUSIONS: Severe comorbidity indicated by a high CCI score (≥3) was the independent predictor for short-term survival for EGC patients without additional gastrectomy after non-curative ESD. Since the cause of death for most patients was not gastric cancer, observational follow-ups without additional gastrectomy might be a reasonable option for patients with a poor general status indicated by a CCI ≥3.

RESUMO

AIMS: Patients with chronic kidney disease (CKD) have a higher burden of cardiovascular morbidity and mortality than the general population. Endothelial dysfunction has been suggested to play a role in both glomerular filtration rate loss and cardiovascular damage. Thus, the present study aimed to evaluate the relationship between endothelial dysfunction and the prevalence of CKD in the general Japanese population. METHODS: We conducted a cross-sectional study of 1042 men and women aged 30-81 years in two communities under the Circulatory Risk in Communities Study between 2013 and 2017. Endothelial function was evaluated by percent change of brachial artery flow-mediated dilation (%FMD) before and after the cuff inflation. RESULTS: Among the total 1042 participants, there were 62 cases of CKD (~6%). The multivariable odds ratios (ORs) (95% confidence intervals [CIs]) of CKD according to quartiles of %FMD were 2.02 (0.68-5.99), 3.56 (1.27-9.94), and 3.14 (1.10-8.93) for the third to lowest quartile compared with the highest %FMD quartile; p for trend=0.02. The respective multivariable ORs (95% CIs) of CKD in subjects without antihypertensive medication use (39 cases among 886 subjects) were 1.83 (0.46-7.33), 3.41 (0.92-12.61), and 4.60 (1.22-17.31); p for trend=0.01, and that for one-point decrement in %FMD was 1.16 (1.00-1.35); p for interaction with the status of antihypertensive medication use was 0.12. CONCLUSIONS: Our cross-sectional study suggested the relationship between endothelial dysfunction and the higher prevalence of CKD in the general Japanese population.

RESUMO

The Fukushima Daiichi Nuclear Power Plant accident occurred on March 11 2011, following the Great East Japan Earthquake and tsunami. Radioactive materials, including I-131, were released into the environment after the accident. Shortly after, the prefectural government initiated the Fukushima Health Management Survey for monitoring the long-term health conditions of the residents of Fukushima Prefecture. In the survey, thyroid ultrasonography was scheduled for all people aged 18 years or younger who were living in Fukushima Prefecture at the time of disaster. The total number of examinees was approximately 370,000 in the Preliminary Baseline Survey (PBLS), and 380,000 in the first Full-scale Survey (FSS). First, thyroid ultrasonography was performed as the Primary Examination. When a thyroid nodule that meets the fine needle aspiration cytology (FNAC) guideline is detected, thyroid FNAC is performed. By the end of June 2017, the cytological specimens of 187 examinees had been interpreted as Malignant or Suspicious for Malignancy (SFM). In this article, the cytological results of whole categories are presented using the criteria of The Bethesda System for Reporting Thyroid Cytopathology. The total numbers of examinees with SFM or Malignant in PBLS and at the first FSS were 106 (62.0%) and 71 (38.0%), respectively. The data of the cytological results of SFM and Malignant were already reported. However, this is the first report of cytological data from categories other than SFM and Malignant. The results of the current study will contribute to future research into the thyroid conditions of children and adolescents.

RESUMO

AIM: After the Great East Japan Earthquake, over 160,000 residents in Fukushima Prefecture were forced to evacuate the area around the Fukushima Daiichi power plant following nuclear accident there. Health problems in these evacuees have since become a major issue. We have examined the association between evacuation and incidence of hyperuricemia among residents in Fukushima. METHODS: We conducted a cohort study of residents aged 40-90 years without hyperuricemia at the time of the Fukushima disaster. Among 8173 residents who met the inclusion criteria before the disaster, 4789 residents (men: 1971, women: 2818; follow-up duration: 1.38 years; and follow-up rate: 58.6%) remained available for follow-up examinations at the end of March 2013. The main endpoint was incidence of hyperuricemia, defined by the Japanese committee guidelines, using local health data from before and after the disaster. We divided participants by evacuation status and compared outcomes between groups. Using a logistic regression model, we estimated the odds ratio for incidence of hyperuricemia, adjusting for potential confounders, age, gender, waist circumference, physical activity, and alcohol consumption. RESULTS: Incidence of hyperuricemia was higher in evacuees (men 10.1%; women 1.1%) than in non-evacuees (men 7.4%, women 1.0%). Evacuees had higher body mass index, waist circumference, triglycerides, LDL-cholesterol, fasting plasma glucose, HbA1c, and lower HDL-cholesterol after the disaster than non-evacuees. We found that evacuation was associated with incidence of hyperuricemia (adjusted odds ratio: 1.38; 95% confidence interval: 1.03-1.86). CONCLUSION: This is the first study to demonstrate an association between evacuation after a disaster and increased incidence of hyperuricemia.

RESUMO

OBJECTIVES: On March 11, 2011, a magnitude 9 earthquake (the Great East Japan Earthquake) occurred off the east coast of Japan. After the Fukushima Daiichi Nuclear Power Plant accidents, as of 2016, people were not allowed to live in the 6 districts (Tomioka, Okuma, Futaba, Namie, Katsurao, Iidate) in Fukushima Prefecture. In the present study, we aimed to evaluate the long-term effects of displacement on all-cause mortality in Fukushima Prefecture. METHODS: Data regarding population and deaths from 2009 to 2016 in Fukushima Prefecture were obtained from the governmental statistics. The age-adjusted all-cause mortality were compared among the 4 areas in Fukushima Prefecture; the Eastern, Middle, Western, and Displacement areas. RESULTS: The age-adjusted all-cause mortality rates in the Eastern and Displacement areas were higher than in the other 2 areas from 2009 to 2011. During the period from 2012 to 2016, all-cause mortality in the Displacement area decreased to the lowest, while the morality in the Eastern area remained the highest. CONCLUSIONS: Against all expectations, after the earthquake, all-cause mortality in the Displacement area was continuously lower than in the rest of the Fukushima Prefecture. Following disasters, long-term monitoring should be organized to meet local health-care needs.

RESUMO

Since Fukushima nuclear accident in 2011, thyroid ultrasound examinations have been conducted. The first full-scale examination detected 71 thyroid-cancer cases. This study examined whether radiation exposure was associated with thyroid-cancer incidence.Subjects were participants in the baseline screening and newborns during the 2011 fiscal year. Under nested matched case-control study design, 10 controls per each case were selected by matching the age, sex, baseline screening results, and interval between examinations. With 3 dose levels of external radiation: 1.3 + mSv (upper), 0.8 to 1.3 (middle), and 0.0 to 0.8 (reference), we applied 2 logistic models adjusting for 3 participation-proportions (primary, secondary, and fine-needle aspiratory cytology), overweight, and the B-result of baseline screening (Model 1), and past medical history, family history of thyroid cancer, and frequencies of eating seafood and seaweed in addition to the parameters in Model 1 (Model 2). We examined each model in 3 ways: (a) excluding subjects with a missing radiation exposure dose; and substituting (b1) median or (b2) mean dose of the municipality with missing dose.Odds ratios (ORs) of middle-dose exposure were (a) 1.35 (0.46-3.94), (b1) 1.55 (0.61-3.96), and (b2) 1.23 (0.50-3.03) for Model 1, and (a) 1.18 (0.39-3.57), (b1) 1.31 (0.49-3.49), and (b2) 1.02 (0.40-2.59) for Model 2. For upper-dose exposure, similar results were obtained. Past medical history was significantly associated (odds ratio  = 2.04-2.08) with both (b1) and (b2) in Model 2.No significant associations were obtained between the external radiation exposure and thyroid-cancer incidence.

RESUMO

AIM: This study aimed to investigate the association between the serum high-sensitivity C-reactive protein (hs-CRP) levels and incident atrial fibrillation risk in the general Japanese population, who have lower hs-CRP levels than the Western population, and assess whether the association is modified by sex, overweight, hypertension, and smoking status. METHODS: We conducted a prospective study in 6517 Japanese men and women aged 40-79 years without atrial fibrillation at baseline and enrolled in the Circulatory Risk in Communities Study (2002-2008). The hs-CRP levels were measured using the latex particle-enhanced immunonephelometric assay. Atrial fibrillation was identified using standard 12-lead electrocardiograms and information on physician-diagnosed atrial fibrillation history from the follow-up surveys. We used a Cox proportional hazard regression stratified by community. RESULTS: During a median follow-up of 11 years, 127 new cases of atrial fibrillation (74 and 53 cases among men and women, respectively) were found. Compared to the lowest quintile of hs-CRP levels, the multivariable hazard ratios (95% confidence intervals) were 2.54 (1.17-5.50), 2.28 (1.06-4.93), 2.92 (1.37-6.23), and 2.77 (1.30-5.91) for the second, third, fourth, and fifth (highest) quintiles, respectively. There was no significant effect modification by sex, overweight, hypertension, and smoking status (P for interaction >0.05). CONCLUSIONS: Elevated hs-CRP levels were significantly associated with increased risk of atrial fibrillation in the Japanese population. The association of hs-CRP levels with incident atrial fibrillation did not vary according to sex, overweight, hypertension status, or smoking status.

RESUMO

This study aimed to investigate associations between Brief Job Stress Questionnaire (BJSQ)-measured job stress factors and sickness absence in Japanese workers. Among 551 healthy, employed Japanese men and women (age range: 21-73 years) who underwent mental health examinations at the Osaka Medical Center for Health Science and Promotion between 2006 and 2009, 197 (67 men, 130 women) consented to participate in this study. Their sickness absences until the end of March 2010 were then followed-up via postal mail survey, with 112 participants effectively responding to the question on sickness absence (56.9%). The hazard ratio (HR) and 95% confidence interval (CI) were calculated using the Cox proportional hazards model, adjusting for age, sex, and lifestyle factors. Among the 112 respondents, 12 took sickness absence after their study entry, as found during the mean 2.3 years of follow-up (258.8 person-years). Among all sickness absences, those of eight participants were because of mental illness. Physical demands were positively associated with increased risks of all sickness absence (adjusted HR: 2.78, 95% CI: 1.01-7.64). Physical demands were predictive for all sickness absence, and should be alleviated at workplaces to prevent such absence.

RESUMO

OBJECTIVE: Dietary patterns more closely resemble actual eating behaviours because multiple food groups, not a single food group or nutrient, are considered. The present study aimed to identify and assess changes of dietary patterns in Fukushima residents. DESIGN: Dietary data were collected using a short-form FFQ in annual Fukushima Health Management Survey between 2011 and 2013 after the Great East Japan Earthquake. Year- and sex-specific dietary patterns were determined by the principal component analysis. SETTING: Evacuation and nonevacuation zones in Fukushima, Japan. PARTICIPANTS: Eligible participants aged ≥16 years answered the FFQ (n 67 358 in 2011, n 48 377 in 2012 and n 40 742 in 2013). RESULTS: Three identified dietary patterns were assessed similarly in men and women and among years: typical, juice and meat. In total participants, the Spearman's correlation coefficients between two survey years were 0·70-0·74 for the typical, 0·58-0·66 for the juice and 0·50-0·54 for the meat pattern scores. Adjusted for sociodemographic factors, evacuees had lower typical pattern scores, higher juice pattern scores and the same meat pattern scores compared with non-evacuees. The means of typical pattern scores in evacuees and it of juice pattern scores in non-evacuees continued declining over years. Similar profiles of dietary patterns and trends of pattern scores were observed in participants (n 22 805) who had provided three dietary assessments. CONCLUSIONS: Changes of dietary patterns have been observed between 2011 and 2013. Careful investigation of those with low intake of typical pattern foods and promotion of them, particularly in evacuees, are needed.
