ABSTRACT
【Objective】 To retrospectively analyze the transfusion records of COVID-19 patients from Feb to Mar 2020 in the Optical Valley Branch of Tongji Hospital in Wuhan, and summarize the clinical features and blood use of those patients. 【Methods】 1) The utilization of blood components in 81 blood recipients were collected and retrospectively analyzed; 2) Propensity score matching (PSM, by the clinical classification of COVID-19) was used to match the transfused and non-transfused patients according to the ratio of 1∶2, and the clinical features of the two groups were compared. 【Results】 The total transfusion rate in our hospital was 5.5%(81/1 463), among which 88.9%(72/81)transfused red blood cell (RBC). Ten patients received RBC transfusion > 20 U, consumed 48.3%(330/680)RBC, 57.5%(53 500/93 100)plasma, 36.2%(42/116)platelets, and 62.3%(114.25/183.25)cryoprecipitates due to ECMO or gastrointestinal bleeding. Compared to non-transfused patients, transfused patients showed worse lab-indexes related to inflammation, infection, and coagulation at admission, higher incidences of acute liver, kidney and cardiac injury, admission to the ICU and mortality(P<0.01). 【Conclusion】 The related functional indexes and prognosis of transfused COVID-19 patients were significantly worse than non-transfused ones. RBC transfusions were dominant, and massive blood transfusions were seldom.
ABSTRACT
Objective@#To provide data support for AIDS prevention and control by investigating HIV testing among technician school students in Guangzhou.@*Methods@#A total of 1 112 students were investigated with a questionnaire about AIDS knowledge, attitude, sexual behavior and HIV testing through a stratified cluster random sampling method in October 2018. A Logistic regression analysis was conducted for influencing factors of students’ HIV testing.@*Results@#The HIV testing rate of technician school student was 10.3%. The HIV testing rate (12.1%-24.3%) of male, under 18 years of age, with monthly living expenses over 3 000 yuan and with poor family atmosphere was higher than that of the corresponding group (6.6%-8.4%), the difference were statistically significant (χ2=12.07,7.25,10.73,9.77, P<0.05). Multivariate Logistic regression analysis showed that <18 years of age, willingness to participate in relevant AIDS prevention activities, homosexuality, “support for multiple sexual partners” and having sexual behavior were associated with more HIV testing(P<0.05).@*Conclusion@#The incidence of sexual behavior of students in technician school is high while the rate of HIV testing is low, especially for male and male homosexuals.The health and education departments should strengthen students’ AIDS counseling and testing services and raise students’ awareness of AIDS risk in order to improve the coverage of students’ HIV testing.
