RESUMEN
Due to the physiological peculiarities of pregnant women, general clinical studies exclude pregnant women. Therefore, there is a lack of evidence of precise medication for pregnant women with diseases worldwide, which poses a significant risk for them to use medication during pregnancy. Whether to include pregnant women as subjects in clinical research has always been a focus of ethical discussion. By providing a broad overview of pregnant women’s participation in clinical research from an ethical perspective, this paper explored the risks and challenges faced by pregnant women’s participation in clinical research, and provided theoretical basis and thinking paths for how to fairly and effectively include pregnant women as subjects and promoting clinical research on pregnant women.
RESUMEN
By searching the papers about medical ethics education in Chinese database CNKI and foreign database Web of Science Core Collection, and using the bibliometrics software CiteSpace to draw the knowledge map of medical ethics education at home and abroad, this paper conducted a quantitative and qualitative analysis of the evolution of hot spots and the development trend of medical ethics education research, and found that the development level of medical ethics education in the world varies greatly. China has experienced the development and evolution from medical ethics education to medical humanities, and its research hotspots mainly focus on the topics of "medical ethics" "medical education" "practice teaching" "medical humanities" "teaching reform" and so on. While foreign countries focus on "medical education" "clinical ethics" "hospice care" "health care" "global public health" "science and technology ethics" "organ transplantation" "curriculum construction" "health policy" and other topics. Through the comparative analysis of the development trend and the evolution of hot spots of education, this paper put forward theoretical reference direction for improving the medical ethics education system in China and further perfecting the discipline construction of medical ethics in China.
RESUMEN
Objective@#To analyze the comparability of different detection systems and methods for tumor markers (TM) by reviewing the results of TM external quality assessment (EQA) in Shandong province during 2015 and 2017. @*Methods@#The results of TM EQA from the Shandong Provincial Clinical Laboratory Center during 2015 and 2017 were collected, and grouped by the detection system or method. After outliers were removed by the CLInet EQA software, the mean and coefficient of variation (CV) in each group were calculated with median as the target value. The difference of TM results in different detection systems were compared by the Kruskal-Wallis H test. @*Results@#Taking alpha-fetoprotein (AFP) as an example, the average CV of different detection methods of TM EQA during 2015 and 2017 ranged from small to large in order of microparticle enzyme immunoassay, electrochemiluminescence, acridine ester chemiluminescence and chemiluminescence. The trends of CV of the other tumor markers were similar to AFP. The average CV of individual marker in electrochemiluminescence group was lower than that in microparticle enzyme immunoassay group. The intra-group CVs of imported detection systems such as Roche, Beckman etc. were relatively ideal, and the average CVs of most tumor markers were less than 10%. However, the intra-group CVs of domestic detection systems such as Shenzhen Snibe, Zhengzhou Autobio etc. were not ideal, and the average CVs of most tumor markers were more than 10%. The target values of different detection systems varied with different items and batches, and there were great variation in carbohydrate antigen (CA) series. @*Conclusion@#The results of TM detected by the same automatic detection system are comparable. However, the results of TM detected by most different detection systems and methods are not comparable.
