Background: Lymphocytes are susceptible to damage from radiation, and the white blood cell (WBC) count, including counts of neutrophils and lymphocytes, is a useful method of dosimetry. According to the basic survey of the Fukushima Health Management Survey (FHMS), among 13 localities where evacuation was recommended, Iitate and Namie had more individuals with external radiation exposure of more than 5 mSv than the other evacuation areas. We analyzed whether or not WBC, neutrophil, and lymphocyte counts decreased after the disaster.Methods: The subjects of this study were 45 278 men and women aged 20 to 99 years (18 953 men and 26 325 women; mean age 56 years) in the evacuation zone who participated in the Comprehensive Health Check (CHC) from June 2011 to the end of March 2012.Results: Significant differences were detected in the mean values of WBC, neutrophil, and lymphocyte counts, and for the proportion of individuals under the minimum standard for WBC and neutrophil counts, among the 13 localities. However, the distribution of individuals at each 200-cell/µL increment in lymphocyte count were similar in these areas, and the WBC, neutrophil, and lymphocyte counts did not decrease in Iitate or Namie specifically.Conclusions: No marked effects of radiation exposure on the distribution of WBC counts, including neutrophil and lymphocyte counts were detected within one year after the disaster in the evacuation zone.

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.

Aim: To assist in the long-term health management of residents and evaluate health impacts after the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey. This report describes the results for residents aged 16 years or older who received the health check examinations and evaluates the data obtained from 2011 and 2012.Methods: The target group consisted of residents aged 16 years or older who had lived in the evacuation zone. The health check examinations were performed on receipt of an application for a health check examination from any of the residents. The examinations, including measurements of height, weight, abdominal circumference/body mass index (BMI), blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required.Results: 1) A total of 56,399 (30.9%) and 47,009 (25.4%) residents aged 16 years or older received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 16-39 year age group were found to suffer obesity, hyperlipidemia, hyperuricemia, or liver dysfunction, and the prevalence of obesity and hyperlipidemia among residents increased with age. Furthermore, the proportion of residents with hypertension, glucose metabolic abnormalities or renal dysfunction was higher in those aged 40 years or older. 3) The frequencies of obesity, hypertension and hyperlipidemia among residents in 2012 were lower than those in 2011. However, the prevalence of liver dysfunction, hyperuricemia, glucose metabolic abnormalities and renal dysfunction among residents was higher in 2012 than in 2011.Conclusions: These results suggested the number of residents who had lived in the evacuation zone with obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, glucose metabolic abnormalities, or renal dysfunction increased with age in all age groups. Therefore, we think that it is necessary to continue with health check examinations for these residents in order to ameliorate lifestyle-related disease.

Aim: After the Great East Japan Earthquake, over 160,000 residents near the Fukushima Daiichi Nuclear Power Plant were forced to evacuate due to a nuclear accident. Health problems in these evacuees have since become major issues. We examined the association between evacuation and incidence of metabolic syndrome (METS) among residents in Fukushima.Methods: We conducted a cohort study among residents aged 40-74 years without METS at the time of the disaster in Fukushima. Among 20,269 residents who met the inclusion criteria before the disaster, 8,547 residents (3,697 men and 4,850 women; follow-up proportion: 42.2%) remained available for follow-up examinations after the disaster by the end of March 2013. The main outcome was incidence of METS, defined by guidelines from the Japanese committee, using data from the Comprehensive Health Check 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 METS, adjusting for potential confounders, age, gender, waist circumference, exercise habit, and alcohol consumption.Results: Incidence of METS was higher in evacuees (men 19.2%, women 6.6%) than in non-evacuees (men 11.0%, women 4.6%). Evacuees had higher body mass index, waist circumference, triglycerides, and fasting plasma glucose after the disaster than non-evacuees. We found a significant association between evacuation and incidence of METS (adjusted odds ratio 1.72, 95% confidence interval; 1.46-2.02).Conclusion: This is the first study to demonstrate that evacuation after a disaster is associated with increased incidence of METS.

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.

A 40-year-old man was transferred to our hospital following an isolated horse kick injury to the anterior chest wall. The case showed bi-fascicular block, severe tricuspid valve regurgitation due to ruptured chordae tendineae of the anterior leaflet, moderate mitral valve regurgitation due to prolapse of mitral anterior leaflet, and hypokinetic motion of the inferior septal wall. Both tricuspid and mitral insufficiency were completely repaired by a surgical operation. Fortunately, these injuries were not fatal in this case, but the comprehensive assessment of cardiac damage and careful observation are important for managing patients with cardiac injury.
