Database structure modification of internal exposure management suited for Japanese alimentation behavior

[Purpose] After the Fukushima nuclear accident, the anxieties about radiation exposure by eating food are growing. Management of internal radiation exposure by food is indicated. The authors have examined a modification of the database structure of an internal exposure management tool that is used in Belarus after the Chernobyl accident to be suited for Japanese alimentation behavior. This poster aims to solve the problem left that the method to constitute a dish is complicated. [Methods] 1) The foodstuffs and the amount of the each ingestion of dish are stored in ‘Ingredients’ table to constitute ingesting dish in the old database structure. In the new database structure, the ingestion of foodstuffs and the recipe of the dish are stored to separate table. The amount of ingested natural and artificial radionuclides are estimated by using the ingestion of foodstuffs. 2) To take into consideration of the estimation with detection limit of the radioactivity inspection, the detection limit value is stored.[Results] This database structure modification makes it easy to constitute ingesting dish reflecting Japanese alimentation behavior. Also, the data amount is up to 97% reduced. The estimation of the internal radiation considering the detection limit is enabled.[Conclusion] This modification makes it easy to constitute ingesting dish reflecting Japanese alimentation behavior. Also, the amount of data is drastically reduced. The authors built an internal exposure management tool with higher usability than the original.ECR2015(第27回欧州放射線学会議

Worldwide Disparities in Recovery of Cardiac Testing 1 Year Into COVID-19

BACKGROUND The extent to which health care systems have adapted to the COVID-19 pandemic to provide necessary cardiac diagnostic services is unknown.OBJECTIVES The aim of this study was to determine the impact of the pandemic on cardiac testing practices, volumes and types of diagnostic services, and perceived psychological stress to health care providers worldwide.METHODS The International Atomic Energy Agency conducted a worldwide survey assessing alterations from baseline in cardiovascular diagnostic care at the pandemic's onset and 1 year later. Multivariable regression was used to determine factors associated with procedure volume recovery.RESULTS Surveys were submitted from 669 centers in 107 countries. Worldwide reduction in cardiac procedure volumes of 64% from March 2019 to April 2020 recovered by April 2021 in high- and upper middle-income countries (recovery rates of 108% and 99%) but remained depressed in lower middle- and low-income countries (46% and 30% recovery). Although stress testing was used 12% less frequently in 2021 than in 2019, coronary computed tomographic angiography was used 14% more, a trend also seen for other advanced cardiac imaging modalities (positron emission tomography and magnetic resonance; 22%-25% increases). Pandemic-related psychological stress was estimated to have affected nearly 40% of staff, impacting patient care at 78% of sites. In multivariable regression, only lower-income status and physicians' psychological stress were significant in predicting recovery of cardiac testing.CONCLUSIONS Cardiac diagnostic testing has yet to recover to prepandemic levels in lower-income countries. Worldwide, the decrease in standard stress testing is offset by greater use of advanced cardiac imaging modalities. Pandemic-related psychological stress among providers is widespread and associated with poor recovery of cardiac testing. (C) 2022 The Authors.
