AbstractPast reports indicated that total-body irradiation at low to moderate doses could be responsible for cardiovascular disease risks, but the mechanism remains unclear. The purpose of this study was to investigate the association between radiation exposure and atherosclerosis, an underlying pathology of cardiovascular diseases, in the Japanese atomic bomb survivors. We performed a cross-sectional study measuring 14 clinical-physiological atherosclerosis indicators during clinical exams from 2010 to 2014 in 3274 participants of the Adult Health Study cohort. Multivariable analyses were performed by using a structural equation model with latent factors representing underlying atherosclerotic pathologies: (1) arterial stiffness, (2) calcification, and (3) plaque　as measured with indicators chosen a priori on the basis of clinical-physiological knowledge. Radiation was linearly associated with calcification (standardized coefficient per Gy 0.15, 95 % confidence interval: CI [0.070, 0.23]) and plaque (0.11, 95 % CI [0.029, 0.20]), small associations that were comparable to about 2 years of aging per Gy of radiation exposure, but not with arterial stiffness (0.036, 95 % CI [− 0.025, 0.095]). The model fitted better and had narrower confidence intervals than separate ordinary regression models explaining individual indicators independently. The associations were less evident when the dose range was restricted to a maximum of 2 or 1 Gy. By combining individual clinical-physiological indicators that are correlated because of common, underlying atherosclerotic pathologies, we found a small, but significant association of radiation with atherosclerosis.

Occupational Radiation

IntroductionAlthough fluoroscopically guided procedures involve a considerably high dose of radiation, few studies have investigated the effects of radiation on medical workers involved in interventional fluoroscopy procedures. Previous research remains in the early stages and has not reached a level comparable with other occupational studies thus far. Furthermore, the study of radiation workers provides an opportunity to estimate health risks at low doses and dose rates of ionising radiation. Therefore, the objectives of this study are (1) to initiate a prospective cohort study by conducting a baseline survey among medical radiation workers who involve interventional fluoroscopy procedures and (2) to assess the effect of occupational radiation exposure and on the overall health status through an in-depth cross-sectional study.Methods and analysisIntervention medical workers in Korea will be enrolled by using a self-administered questionnaire survey, and the survey data will be linked with radiation dosimetry data, National Health Insurance claims data, cancer registry and mortality data. After merging these data, the radiation organ dose, lifetime attributable risk due to cancer and the risk per unit dose will be estimated. For the cross-sectional study, approximately 100 intervention radiology department workers will be investigated for blood tests, clinical examinations such as ultrasonography (thyroid and carotid artery scan) and lens opacity, the validation of badge dose and biodosimetry.Ethics and disseminationThis study was reviewed and approved by the institutional review board of Korea University (KU-IRB-12-12-A-1). All participants will provide written informed consent prior to enrolment. The findings of the study will be disseminated through peer-reviewed scientific journals, conference presentations, and a report will be submitted to the relevant public health authorities in the Korea Centers for Disease Control and Prevention to help with the development of appropriate research and management policies.

ABSTRACT A retrospective and cross-sectional study of canine tumors was performed in the capital of State of Mexico from 2002-2016. Since then, 393 tumors were remitted. Descriptive epidemiology was made from all data: breed, age, sex, and tumor features. Then the risk association between cutaneous and non-cutaneous tumors with variables such as sex, breed, and age were analyzed through an exact Fisher test and Odds ratio. In addition, some characteristics of the canine population were studied under a survey. Of all tumors, skin tumors were the most frequent (59.0%). The group of tumors related to ultraviolet radiation was the most common (15.1%). The frequency of tumors in females was 53%, nevertheless, males had more risk to develop cutaneous tumors (OR=1.88, 1.24-2.84) (0.003). The Pure breeds were the most common (82.5%) and the most frequent age range was > 7 years (54.7%). The survey showed that males (53%) and the age range 1-7 years (62.1%) were the most frequent. Conclusions, age, breed, and sex were identified as the major risk factors for tumorigenesis. Likewise, skin tumors were associated with exposure to ultraviolet radiation, probably to the height of the locality (2667mamls).

Introduction: Radiological investigations form a cornerstone in the management of patients. Patient might me unware of the radiation exposure. The aim of this study is to assess patient’s knowledge of radiation exposure to common diagnostic imaging procedures.Methods: A cross-sectional study was conducted and questionnaire used to collect data from 216 patients who had undergone radiological investigations.Results: Among 216 patients, there were 112 (51.85 %) females and 104 (48.15 %) males. The age of the patients ranged from 12 years to 66 years. Only 65 patients (30.1 %) were aware of the radiation hazards. Neoplasm was the most common side effect chosen by 60 patients. 44 patients were informed of radiation hazards with only 17 patients however informed by the referring doctor. Patients having undergone radiological procedure previously were more aware of radiation hazards (21 patients out of 26 patients).Conclusion: This study showed dearth of knowledge and awareness regarding radiation hazards amongst general public which mandates education.
