Objective We conducted the present study to evaluate the prevalence of chronic kidney disease (CKD) and CKD complications among evacuees and non-evacuees after the Great East Japan Earthquake and Fukushima Daiichi nuclear disaster. Methods Twenty-seven thousand and eighty-eight subjects who were living near the Fukushima Daiichi Nuclear Power Plant in Fukushima Prefecture in Japan, aged ≥40 years by the Heath Care Insures, were included in the analyses. Metabolic factors were compared between the evacuees and non-evacuees stratified by the eGFR and proteinuria grades. Results The prevalence of CKD with a low eGFR (<60 mL/min/1.73 m2) and proteinuria were 21.59% and 1.85%, respectively. The risk of CKD complications was classified into four grades according to the eGFR and proteinuria grades. The prevalence of diabetes, hypertension, and dyslipidemia were significantly higher in the very high risk group than in the low risk group. The prevalence of diabetes and dyslipidemia were significantly higher in evacuees than in non-evacuees in only the low risk group. However, a multivariate logistic regression analysis showed that evacuation was not significantly associated with the risk of a low eGFR or proteinuria. Conclusion This study did not reach the definitive conclusion that evacuation elevated the risk of CKD complication, although evacuation might lead to increased CKD complications in the future. We believe that this information is important for follow-up and lifestyle change recommendations for evacuees.

In the Sea of Japan, changes in the oceanographic conditions affect fisheries, and new phenomena such as blooms of the harmful dinoflagellate Margalefidinium polykrikoides and mass occurrences of the giant jellyfish Nemopilema nomurai have been observed since the 2000s. In order to elucidate and formulate countermeasures to such new issues, it is essential to enhance the oceanographic/biological data. However, data especially on the phytoplankton assemblage are limited. In the present study, we investigated the population dynamics of the phytoplankton community together with environmental factors at two stations off Tajima, southwestern Sea of Japan for seven fiscal years from September 2009 to March 2016. The oceanographic observations revealed the general pattern in the seasonal and annual abundance of phytoplankton off Tajima. The major component of size-fractionated chlorophyll a concentrations were micro-size (filtered pore size: >10 µm). The results indicated that there was usually a low abundance of phytoplankton in this area. Relatively high abundances (cell densities over 100 cells mL−1) of micro-sized phytoplankton were observed only in spring, but total cell densities were less than 10 cells mL−1 in most months of the other three seasons. The major phytoplankton component was diatoms. Based on the abundance and frequency, the dominant seven diatom taxa were classified into three groups: Skeletonema spp., Thalassiosira spp. and Eucampia zodiacus were dominant in spring, Chaetoceros spp. and Pseudo-nitzschia spp. were dominant in spring and autumn, and Rhizosolenia spp. and Leptocylindrus danicus were dominant in autumn.

Objective The Great East Japan Earthquake and the Fukushima Daiichi nuclear disaster forced the evacuation of residents and led to many changes in the lifestyle of the evacuees. A comprehensive health check was implemented to support the prevention of lifestyle-related disease, and we analyzed changes in lipid metabolism before and after these disasters. Methods Subjects included Japanese men and women living near the Fukushima Daiichi nuclear power plant in Fukushima Prefecture. Annual health checkups, focusing on metabolic syndromes, were conducted for persons ≥40 years of age by the Heath Care Insures. Results A total of 27,486 subjects underwent a follow-up examination after the disaster, with a mean follow-up of 1.6 years. Following the disaster, the prevalence of hypo-high-density lipoprotein (HDL) cholesterolemia increased significantly from 6.0% to 7.2%. In the hypo-HDL cholesterolemia group, the body mass index (BMI), blood pressure, and LDL-C level increased significantly in men after the disaster. On the other hand, in the normal HDL-C level group, the BMI, blood pressure, glucose and lipid metabolism, and liver function were adversely affected. The decrease in HDL-C was significantly greater in evacuees than non-evacuees in the normal HDL-C level group. Furthermore, a multivariate logistic regression analysis showed that the evacuation was significantly associated with the incidence of hypo-HDL cholesterolemia. Conclusion This is the first study to evaluate how the evacuation affected the incidence of hypo-HDL cholesterolemia and led to an increase in cardiovascular disease. This information may be important in the follow-up and lifestyle change recommendations for evacuees.

Objective Whether or not combined lifestyle factors are associated with similar decreases in risks of incident hypertension and diabetes among individuals with and without chronic kidney disease (CKD) remains unclear. Methods This population-based prospective cohort study included participants 40-74 years old who were free from heart disease, stroke, renal failure, hypertension, diabetes, and hypercholesterolemia at baseline (n =60,234). Healthy lifestyle scores (HLSs) were calculated by adding the total number of 5 healthy lifestyle factors (non-smoking, body mass index <25 kg/m2, regular exercise, healthy eating habits, and moderate or less alcohol consumption). Cox proportional hazards models were used to examine associations between the HLS and incident hypertension or type 2 diabetes and whether or not CKD modified these associations. Results During a median of 4 years, there were 2,773 incident hypertension cases (30.1 cases per 1,000 person-years) and 263 incident diabetes cases (2.4 cases per 1,000 person-years). The risk of developing hypertension and diabetes decreased linearly as participants adhered to more HLS components. Compared with adhering to 0, 1, or 2 components, adherence to all 5 HLS components was associated with a nearly one-half reduction in the risk of hypertension (hazard ratio [HR] =0.52; 95% confidence interval [CI], 0.45-0.60) and diabetes (HR =0.51; 95% CI, 0.32-0.81) in fully adjusted models. CKD did not have a modifying effect on associations between the HLS and incident hypertension (Pinteraction =0.6) or diabetes (Pinteraction =0.3). Conclusion Adherence to HLS components was associated with reduced risks of incident hypertension and diabetes, regardless of CKD status.

Background: Aortic artery disease (AAD), such as aortic dissection or aortic aneurysm rupture, is fatal, with an extremely high mortality. Because of its low incidence, the risk for the development of AAD has not yet been elucidated. Hypertension (HT) is an established risk factor for cardiovascular disease, but there has been no prospective study on the effect of HT on AAD-related mortality. Methods and Results: We used a nationwide database of 276,197 subjects (aged 40–75 years) who participated in the annual “Specific Health Check and Guidance in Japan” from 2008 to 2010. There were 80 AAD-related deaths during the follow-up period of 1,049,549 person-years. On multivariate Cox proportional hazard regression, HT was an independent risk factor for AAD-related death in apparently healthy subjects. On receiver operating characteristics curve analysis for AAD-related death, abnormal systolic and diastolic blood pressure (SBP and DBP) were 130 mmHg and 82 mmHg, respectively. The prediction capacity was significantly improved by the addition of SBP to confounding risk factors. Notably, further improvement of the C index was observed by addition of DBP to the model with SBP. Conclusions: This is the first report to prospectively show that HT is a risk factor for AAD-related death. Both SBP and DBP are of critical importance in the primary prevention of AAD-related death in apparently healthy subjects.

Aims: Several guidelines propose target levels (TLs) of atherosclerotic risk factors (ARFs) to reduce atherosclerotic cardiovascular diseases; however, few data are available regarding the attainment statuses of TLs in Japan. In this study, utilizing the data obtained from the annual “Specific Health Check and Guidance in Japan” conducted from 2008 to 2011 (approximately 280,000 subjects each year), we determined TL attainments of ARFs in cardiovascular high-risk subjects.Methods: Those who had suffered from cerebrovascular disease (pCVD) or coronary heart disease (pCHD) or were receiving diabetes mellitus treatment (DM) were selected, and the rates of subjects that attained TLs of blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs) and glycated hemoglobin (HbA1c) were analyzed.Results: Approximately 70% of pCVD or pCHD and 35% of subjects with DM attained TLs of BP. With regard to HbA1c, >90% of pCVD or pCHD and approximately 50% of subjects with DM attained TLs. With regard to LDL-C, <25% of pCHD females and approximately 35% of pCHD males and 50%–55% of subjects with pCVD or DM attained TLs. The TL-attainment rates of HDL-C and TGs were approximately 90% and 75%, respectively, for the three diseases. Analyses of time course changes in their attainment statuses revealed that the attainment rates of BP and LDL-C significantly improved in all the diseases.Conclusions: TL-attainment rates of BP and LDL-C were not as high as those for HDL-C, TGs, and HbA1c; however, they both showed highly significant improvements during the study period.
