RESUMO
ABSTRACT Introduction: Time series studies related to blood donor candidates and blood donations are rare in Brazil. Population aging suggests a better understanding of the context related to blood donor candidates and blood donations performed. Objective: The monthly series of candidates eligible to donate blood and actual donations between 2005 and 2019 at the Hemominas Foundation, Minas Gerais, Brazil, were described and analyzed. Methods: Ten time series were constructed of blood donor candidates and blood donations. Each series covered the period from January 2005 to December 2019. The stationarity of the series was verified by the unit root test; the data distribution, by the Shapiro-Wilk test; the trend, by the Cox-Stuart test, and; the seasonality, by the Fisher's test (significance levels of 10% for the first test and 5% for the last three). Results: All series were identified as non-stationary and presented trend and seasonality components. The rate of blood donor candidates and the rate of blood donations performed evidenced a positive upward trend until the last two-year analysis, when a drop occurred, from 1.75% and 1.42% in 2017 to 1.64% and 1.35% in 2019, respectively. The rate of blood donations trended downward, from 0.054% in 2005 to 0.046% in 2019. The proportion of unsuitable or unretained candidates reduced. Conclusion: The study emphasized the need to stimulate blood donation by specific groups and increase ways to reduce the demand for blood components through the implementation of programs that expand alternatives to blood transfusions.

【Objective】 To investigate the impact of ceasing mutual blood donation on voluntary blood donation in Guangzhou. 【Methods】 The data of blood donation from July 2016 to December 2019 (42-month before and after the official cease of mutual blood donation) in the Blood Collection and Supply System of Guangzhou Blood Center, including whole blood donations and apheresis platelets donations, were collected for interrupted time series analysis by month. Blood donors who donated (either whole blood or platelets) during 2016 were followed up until December 31, 2019, and the re-donation rate was analyzed by Chi-square test, t test and logistic regression analysis. 【Results】 The results showed that ceasing mutual blood donation had a significantly positive effect on the increase of platelet donations, but had no significant effect on whole blood donation. In 2016, whole blood donations and platelet donations were mainly voluntary (86.4% and 60.8%, respectively). In comparison of voluntary blood donation, the overall blood deferral rate(by dual assays) of mutual blood donation was higher (P<0.01), but the difference diminished as they donated twice or more. The re-donation rate of blood donors (mutual non-remunerated, voluntary, or both) all increased after the ceasing of mutual blood donation (mutual non-remunerated, : 4.7% vs 4.0%, χ2=29.8, P<0.01; voluntary: 24.8% vs 9.9%, χ2=17295.3, P<0.01; both: 36.3% vs 28.1%, χ2=29.3, P<0.01). The re-donation rate of mutual platelet donors decreased after the ceasing of mutual blood donation, but the number of voluntary platelet donors increased. 【Conclusion】 The ceasing of mutual blood donation was in favour of voluntary blood donation in Guangzhou since various means had been previously adopted by Guangzhou Blood Center to create a long-term mechanism of voluntary blood donation. The number of voluntary blood donors has increased, and the clinical use of blood has been further guaranteed.
RESUMO
【Objective】 To study and analyze the basic characteristics of blood donors under the COVID-19 epidemic in Tianjin area, so as to provide data support for improving the blood collection for emergency incidents. 【Methods】 The blood collection data of Tianjin Blood Center under the COVID-19 epidemic in 2020 were collected in terms of the number of blood donations, changes in blood donation units over time, group blood donation, donations given by regular blood donors and donations inside fixed blood donation sites, registered residence, gender, age, education, occupation, individual donation, group donation, and the annual daily blood collection and delivery data in Tianjin. 【Results】 The number of blood donations and donation units in Feb 2020 decreased by 56.96%(3 226/7 496-1)and 62.40%(5 382/14 314.5-1)compared with the same period in 2019, and decreased by 56.87%(3 226/7 480-1)and 60.70%(5 382/13 695.7-1)compared with the average value in the previous five years. The number of blood donations, donation units and rate of 400 mL donation in 2020 decreased by 13.25%(119 107/137 293-1), 17.7%(205 196.5/249 405-1)and 12.83%(66.0/75.8-1)respectively. Meanwhile the units of group donation increased by 22.59%(44 118.5/35 989.0-1)as compared with those in 2019. The proportion of regular blood donors raised up to 17.31%(20 623/119 107, which was the highest in recent 6 years. During the epidemic period, the number of blood donations of local registered residence, women, over 36 years old, with bachelor and above degree increased by varied extent compared with previous years. Workers, staff members and others were the main groups of voluntary blood donation, and civil servant, medical workers, farmers and teachers also played a certain role during the epidemic. 【Conclusion】 The clinical blood use in Tianjin was basically guaranteed during the COVID-19 epidemic. It is suggested to further optimize the structure of voluntary blood donors, establish a diversified and multi-level group blood donation team, and increase the number of regular blood donors.

RESUMO
OBJETIVO: Determinar la prevalencia de infecciones virales (VHB, VHC y VIH) en período de ventana serológica en donadores de sangre evaluados con la prueba de ácidos nucleicos (NAT). MATERIALES Y MÉTODOS: Se incluyeron donadores de sangre evaluados de 2008 a 2009 con pruebas serológicas y moleculares del VHB, VHC y VIH. El período de ventana serológica se definió con la prueba de NAT positiva y la prueba serológica negativa. RESULTADOS: Durante un año se evaluaron 47 847 donadores de sangre; no se identificó ningún caso con infección viral (VHB, VHC y VIH) en período de ventana serológica; únicamente se demostró NAT positivo en donadores con pruebas serológicas positivas: 26 de 78 con VHB, 56 de 318 con VHC y 16 de 155 con VIH. CONCLUSIÓN: Este es el primer estudio en México que demostró en donadores de sangre la ausencia de infecciones virales (VHB, VHC y VIH) en período de ventana serológica con la prueba de NAT.
OBJECTIVE: To determine the prevalence of viral infections (HBV, HCV and HIV) in serological window period in blood donors screened with nucleic acid testing (NAT). MATERIALS AND METHODS: We assessed all blood donors from July 2008 to June 2009 at the Central Blood Bank of the Mexican Institute of Social Security. Medical history was made and provided an information brochure and self-exclusion questionnaire. All blood donors were tested with serological tests (Ag-HBVs, Anti-HCV and Anti-HIV) and molecular testing with NAT for HBV, HCV and HIV. The window period was defined with the positive NAT and negative serological test. RESULTS: During one year, we evaluated 47 847 blood donors. None subject was identified with viral infection (HBV, HCV and HIV) in serological window period. Positive serological testing were found for HBV in 78 (0.2 percent), 318 (0.7 percent) for HCV and 155 (0.3 percent) for HIV. Positive NAT was demonstrated only in donors with positive serology: 26 of 78 with HBV, 56 of 318 with HCV and 16 of 155 with HIV. CONCLUSION: This is the first study in México showed no viral infections (HBV, HCV and HIV) during serological window period in blood donors; The medical history and the self-exclusion questionnaire help to improve blood transfusion safety.
