RESUMEN
ObjectiveTo monitor the microbes in urban drinking water in Jiangxi from 2016 to 2020， to analyze the change in microbial qualification rate， and to provide a scientific basis for government decision-making. MethodsAccording to the Standard Examination Method for Drinking Water （GB/T 5750‒2006） and the Standards for Drinking Water Quality （GB 5749‒2006）， the water samples were collected， tested and evaluated for hygienic safety. The chi-square test was used to compare the qualification rates among different water periods， water source types， water supply modes， water samples， treatment processes， and disinfection methods. ResultsA total of 10 584 water samples were collected and examined from 2016 to 2020，with a qualification rate of 97.72%. The qualified rate of the microbiological index increased gradually over the years. There was no statistically significant difference in the microbiological qualification rate of water samples monitored in different water periods （χ2=0.718，P=0.398）， and the qualification rates were 97.85% and 97.60% in dry and abundant water periods respectively. There was a statistically significant difference in the qualification rates of water samples monitored in different water source types （χ2=79.560，P=0.398）， with groundwater having a higher qualification rate of 98.83% than surface water （97.70%）. The microbiological pass rate of water samples differed among different water supply methods （χ2=201.836，P<0.001）. The microbiological pass rates of municipal centralized water supply， self-built centralized water supply and secondary water supply were 97.51%， 88.94% and 96.56% respectively. The microbiological pass rates of water samples differed among different treatment processes. There were differences in the qualification rates of the water samples between different treatment processes（χ2=855.034，P<0.001）， with 98.22%， 67.19%， 95.60% and 53.13% of the conventionally treated， precipitated filtered， disinfected only and untreated water samples， respectively. The differences in the microbiological qualification rates of the monitored water samples between different disinfection methods were statistically significant （χ2=904.993，P<0.001）. Chlorination disinfection， chlorine dioxide disinfection， other disinfection methods and non-disinfected water samples had the pass rates of 98.35%， 98.19%， 84.38% and 60.16%， respectively. ConclusionThe qualified rate of the microbiological index of drinking water in Jiangxi increases year by year， but there are still some drinking water without appropriate disinfectants and water quality treatment processes. There is still a need to strengthen the purification， disinfection and monitoring of drinking water.
RESUMEN
Objective:To analyze the competence assessment examinations of registered dietitians in China during 2017-2021 to inform the training of dietetic professionals.Methods:A systematic review was conducted about the composition and changing trends of examination participants during 2017-2021. Participants were divided into subgroups based on gender, age, education, professional background and affiliations and the qualification rate was compared across different subgroups.Results:The number of examination participants showed an increasing trend overall, with the majority being females and aged 26-35 years. The ratio of participants with bachelor's: master's: doctor's degree was about 15: 9: 1. The proportion of participants majoring in nutrition science decreased from 32.1% to 20.3%, while that of participants majoring in other medical and food sciences increased. Among participants from healthcare institutions, a decreasing proportion of participants were with a major in nutrition science, while this proportion among participants from companies were stable at 38.8% to 50.2%. The average qualification rate was 35.7%, showing no significant differences among different gender and age groups. But the qualification rate varied significantly across subgroups with different education level, professional background, and affiliations ( P < 0.05). Subgroups with more advanced degrees showed higher qualification rate and the best rate was observed in the subgroups with professional background in nutrition science and from nutrition-related institutions. Conclusion:The training of dietetic professionals in China should be improved, lifelong learning should be promoted in nutrition practitioners, and the sustainable development of dietitians should be impelled.
RESUMEN
Objective:To determine the disinfection effect in child care institutions in Qingpu District of Shanghai， and provide evidence for improving the disinfection quality and preventing and controlling infectious diseases. Methods:According to the monitoring program of disinfection quality in child care institutions in Shanghai， disinfection quality was monitored for 3 years. Results:A total of 979 samples were monitored in the consecutive three years， in which 895 samples were qualified with a total qualification rate of 91.42%. The qualification rate of air samples was 100.00%， while the rate of staff hand samples was the lowest， with an average of 79.60%. During 2016-2018， the difference among the annual qualification rates was statistically significant（χ2=23.809，P<0.05）， whereas it was not significant in the rates between public institutions and private ones （χ2=0.141，P>0.05）. Conclusion:The quality of preventive disinfection in child care institutions in Qingpu District is generally good， but the disinfection of tableware， surface of objects and staff needs to be further improved.
RESUMEN
OBJECTIVE: To evaluate the effects of prescription evaluation system and the role of pharmacists through the analysis of the results of antibiotic prescription evaluation. METHODS: Random results evaluation analysis based on the results of prescription evaluation in paper during January 2013 to February 2015 and comments of software analysis during March to December 2015. RESULTS: The qualification rates of prescription are respectively 91.6%, 96.5% and 99.1% during 2013-2015 and the consistency of pharmacists and experts are respectively 88.6%, 89.3%, 97.9%, the types of unqualified prescription decrease. CONCLUSION: The evaluation system of antimicrobial agents prescription has accomplished transition from random evaluation of paper prescription evaluation to software ones, which fulfills the mode of prescription evaluation by information techniques.The improving consistency of pharmacists and experts indicates the professional standards of pharmacists.
