Background Safety of evacuation is paramount importance in disaster planning for elderly people; however, little effort has been made to investigate evacuation-related mortality risks. After the Fukushima Daiichi Nuclear Plant accident we conducted a retrospective cohort survival survey evacuees. Methods A total 715 residents admitted five nursing homes Minamisoma city, Prefecture years before 11th March 2011 joined this study. Demographic and clinical characteristics were drawn from...
ABSTRACT Objective To elucidate the impacts of nuclear plant accidents on neighboring medical centers, we investigated operations our hospital within first 10 days Great East Japan Earthquake followed by Fukushima Daiichi power accident. Methods Data were extracted from records and administrative covering 11 to 20 March 2011. Factual information disaster was obtained public access media. Results A total 622 outpatients 241 inpatients treated. Outpatients included 43 injured, 6 with...
Resettlement to their radiation-contaminated hometown could be an option for people displaced at the time of a nuclear disaster; however, little information is available on safety implications these resettlement programs. Kawauchi village, located 12–30 km southwest Fukushima Daiichi power plant, was one 11 municipalities where mandatory evacuation ordered by central government. This village also first municipality organize return villagers. To assess validity villagers' program, levels...
Maintaining low levels of chronic internal contamination among residents in radiation-contaminated areas after a nuclear disaster is great public health concern. However, the efficacy reduction measures for individual remains unknown. To reduce high radiation exposure group individuals exposed through environmental sources, we performed careful dietary intervention with identification suspected contaminated foods, as part mass voluntary screenings and counseling program Minamisoma Municipal...
Chronic internal radiation contamination accounts for a substantial fraction of long-term cumulative exposure among residents in radiation-contaminated areas. However, little information is available on ongoing chronic near the crippled Fukushima Daiichi nuclear power plant. Using whole body counter, levels elementary and middle school students who commute to 22 schools located within Minamisoma city were assessed between May July 2013 (26 28 mo after disaster). Of 3,299 city, 3,255...
An assessment of the external and internal radiation exposure levels, which includes calculation effective doses from chronic long-term radiation-related health risks, has become mandatory for residents living near nuclear power plant in Fukushima, Japan. Data all primary secondary children Minamisoma who participated both screening programs were employed to assess annual additional dose acquired due Fukushima Daiichi disaster. In total, 881 took part between 1st April 2012 31st March 2013....
After a major radioactive incident, accurate dose reconstruction is important for evaluating health risks and appropriate radiation protection policies. the 2011 Japan Fukushima nuclear we assessed level of agreement between modeled directly measured estimated uncertainties. The study population comprised 520 school children from Minamisoma city, located 20 km north plant. annual 18–30 months after incident was using two approaches: estimation model proposed by Japanese government direct...
Japan is rapidly becoming a full-fledged aged society, and physician shortage significant concern. The Japanese government has increased the number of medical school enrollments since 2008, but some researchers warn that this increase could lead to surplus in future. It unknown how many physicians will be required accommodate future healthcare needs.We simulated changes age/sex composition population, fatalities (the for consecutive five years), from 2010 2035. Two indicators were defined:...
Disaster has a negative impact on health conditions, especially those of temporary housing residents. Health status close relationship with physical activity and performance. However, few reports have assessed performance among residents living in housing. In this study, we compared capabilities between the elderly who evacuated to stayed their own homes after Great East Japan Earthquake. Subjects were recruited from over 65 years age participated medical check-ups for (TH group) or downtown...
Background: The Fukushima Dai-ichi nuclear disaster, the first level-7 major disaster since Chernobyl, raised concerns about future health consequences of exposure to and intake radionuclides. Factors determining risk level internal radiation contamination after a accident, which are key understanding improving current management, not well studied.Objective: We investigated both prevalence in residents Minamisoma, identified factors levels contamination.Methods: implemented program assessing...
Thyroid dysfunction after bone marrow transplantation (BMT) has been investigated in many studies, and most posttransplant thyroid disorders are now recognized as a late complication of transplantation. However, these studies mainly focused on function BMT, we have little information early changes BMT.We prospectively 57 patients receiving BMT. Serum thyroid-stimulating hormone, free triiodothyronine, thyroxine levels were determined at least monthly the first 3 months, once between 12...
Various angiogenic factors, such as vascular endothelial growth factor (VEGF) and an associated molecule, placenta (PlGF), are thought to be important for normal malignant hematopoiesis. This study examined mRNA expression of VEGF, PlGF receptors these molecules in AML cells identified the disease-specific patterns expression. M3 having t(15;17) abnormality showed highest VEGF receptor type 1 (VEGFR1), suggesting autocrine pathway VEGF-VEGFR1. Then, t(8;21) demonstrated augmented 2 (VEGFR2),...
After radioactive incidents, the exposure risk in daily activities among children is a major public concern. However, there are limited methods available for evaluation of this risk, which essential to future health management. To end, study assessed relationship between behavioral patterns school and radiation period 18–20 months following 2011 Fukushima nuclear incident. The population comprised 520 from Minamisoma city, located 20 km north plant. Data doses were obtained using individual...
After a radiation-release incident, intake of radionuclides in the initial stage immediately following incident may be major contributor to total internal radiation exposure for individuals affected areas. However, evaluation early contamination risk is greatly lacking. This study assessed relationship between evacuation/indoor sheltering and levels 4 months after 2011 Fukushima nuclear Japan estimated potential pathways contamination. The population comprised 525 participants screening...
Decontamination workers may face a high risk of exposure to internal irradiation through inhalation during decontamination activities; there is, however, little previous research on the levels contamination procedures. The authors reviewed medical records, including whole body counter measurements, in villages near crippled Fukushima Daiichi Nuclear Power Plant assess their radiation exposure. In total, 83 were enrolled this study. They regularly engaged activities highly contaminated areas...
Influenza vaccination is necessary to reduce severe influenza complications, especially in immunocompromised people such as cancer patients. However, few studies have examined uptake among adult Japanese patients with cancer; their attitudes toward vaccination, well factors related vaccine hesitancy, are unclear. From September 1 October 31, 2020, we disseminated a web-based questionnaire history of via snowball sampling through e-mails and social media two associations. A total 163 surveys...
Liver injury is a common complication in allogeneic hematopoietic stem cell transplantation. Its major causes comprise graft-versus-host disease (GVHD), infection, and toxicities of preparative regimens immunosuppressants; however, we have little information on liver injuries after reduced intensity cord blood transplantation (RICBT). We reviewed medical records 104 recipients who underwent RICBT between March 2002 May 2004 at Toranomon Hospital. Preparative regimen GVHD prophylaxis...
