RESUMO
【Objective】 To analyze the disease burden of benign prostatic hyperplasia (BPH) in China, Japan and South Korea from 1990 to 2019, so as to provide scientific basis for rational allocation of health resources. 【Methods】 Data were obtained from the Global Burden of Disease Study 2019. The incidence, prevalence and years lived with disability(YLD)were used to analyze the burden, and the average annual percent change and annual percent change were calculated. 【Results】 The incidence, prevalence and YLD rate in China were much higher than those in Japan and South Korea. The crude incidence in China, Japan and South Korea increased by 2.56%, 1.49% and 3.59% per year from 1990 to 2019, the crude prevalence rate increased by 2.70%, 2.34% and 4.03%, and the crude YLD rate increased by 2.68%, 2.33% and 4.04%. After age standardization, the disease burden in China decreased with time, but the trend was not significant, and the standardized rate in Japan and Korea increased significantly with time. The disease burden of BPH increased with age, and those aged 60 to 84 years had the highest burden. In addition, the disease burden increased with the increase of socio-demographic index (SDI) in all three countries. 【Conclusion】 The disease burden of BPH was very heavy in China, Japan and South Korea, especially in China. Males aged 60 to 84 years were the high-risk group. Targeted intervention should be adopted for these population.
RESUMO
Objective:To survey and supervise the risk of infection control and radiation safety in the radiological diagnostic workplace for COVID-19, and provide data support for the safety protection of radiographers and related staff.Methods:4 emergency hospitals for COVID-19 including 2 makeshift hospitals, module hospital and brick pattern hospital in Hubei province were performed for testing and evaluation of imaging performance and radiological protection for the 8 new installed CT scanners and places according to the national standards of WS 519-2019 and GBZ 130-2013. The infection control safety factors such as the layout of the equipment room were monitored and investigated. Two COVID-19 designated hospitals including general hospital and infectious disease specialized hospital were selected to carry out field investigation and sampling of environmental biological samples for 4 CT rooms. Then the samples were detected for the nucleic acid of novel coronavirus. The results of radiodiagnostic workplace overall arrangement, infection prevention and the nucleic acid testing were analyzed, and the biological safety reliability and risk point were evaluated.Results:The indicators of imaging performance and radiation protection for 8 CT scanners in emergency hospitals could meet the requirements of national standards.Each of 2 makeshift hospitals had 3 CT rooms with the area of 38.8 m 2 and 4 mm Pb equivalent thickness of protective shielding. The CT rooms in module hospital and brick pattern hospital were 20.0 m 2, and 35.8 m 2 in areas, with 4 mm Pb equivalent and 3 mm Pb equivalent thickness of protection shielding, respectively. The 8 radiological diagnostic workplaces of the emergency hospitals were designed and constructed based on " three zones with two passage ways" . The result of the nucleic acid test indicated that the positive samples were found at the multiple sites such as scanning bed, internal of gantry and ground touched by patients in CT scanning room. The areas such as console panel and ground were risked of pollution by the virus infected hands and feet of radiographers. In addition, the similar positive samples were found in the areas in scanning room with no touch of patients, such as observation window and air outlet. Conclusions:8 CT scanners and rooms in 4 emergency hospitals basically meet the requirements of imaging performance and radiation protection. The disinfection of COVID-19 radiodiagnostic workplace should be standardized.
