Objective
To detect the differentially expressed regulatory miRNAs in the late stage of red blood cell (RBC) preservation and predict their roles.
Methods
Suspended RBCs with different storage periods of 35 day, 42 day, and 50 day were collected for routine blood tests, RNA extraction, and preparation of small RNA sequencing libraries. The constructed libraries were sequenced and the biological functions of differential miRNAs in RBCs in the late storage were analyzed by bioinformatics.
Results
Routine indicators of RBCs in the late stage were not significantly affected by preservation time. The Pearson correlation analysis performing on RBC miRNAs with different storage days revealed that RBC miRNAs changed with the increase of storage days. RBC miRNAs from day 35 (D35), day 42 (D42) and day 50 (D50) showed significant differences (P < 0.05). Compared RBC miRNAs from D42 with these from D35, there were 690 up-regulated miRNAs and 82 down-regulated miRNAs; compared RBC miRNAs from D50 with these from D35, there were 638 up-regulated miRNAs and 123 down-regulated miRNAs; compared RBC miRNAs from D42 with these from D50, there were 271 up-regulated miRNAs and 515 down-regulated miRNAs. GO enrichment analysis of target genes of differential miRNAs were mainly involved in cell metabolism, biosynthesis, protein modification, gene expression and transcriptional regulation of biological processes. KEGG pathway enrichment analysis of miRNA target genes showed that differential miRNA target genes were closely related to pathways in cancer.
Conclusion
MiRNAs were differentially expressed in the late stage of RBC preservation, and may be involved in various biological processes, especially cancer.

Recent reports have highlighted that allogeneic blood transfusions decrease immune responses and affect patient outcomes. However, the effects of allogeneic red blood cell transfusions on the composition of immune cells are unclear. We aimed to clarify the alterations in host immune cells in patients who received allogeneic red blood cell transfusions during the perioperative period of cardiovascular surgery.
Materials and Methods
Eight non-transfused, 22 intraoperative autotransfusions, and 36 allogeneic red blood cell-transfused patients undergoing surgery were grouped, and lymphocyte subsets were analyzed using flow cytometry. Blood samples collected before surgery, approximately 1-week, and 1-month after surgery were used for analysis. Surgical parameters, operation time, blood loss, and length of hospital stay were also assessed.
Results
The group receiving transfusions showed statistical significance compared to non-transfused in the above-mentioned surgical parameters. When comparing the autologous and allogeneic transfusion groups, only the allogeneic red blood transfusion group had a longer hospital stay. In comparing preoperative and 1-week and 1-month postoperative samples, there were almost no differences in CD4, CD20, or NK counts between the autotransfusions and the allogenic red blood cell transfusion groups. In contrast, a significant decrease in lymphocyte count was observed in the allogenic red blood cell transfused group 1-week postoperatively compared to preoperatively. Moreover, the number of CD8 + cells was statistically lowest in the allogeneic transfusion group 1 week after the operation.
Conclusion
Our results suggest that allogeneic red blood cell transfusion could alter immune cell composition especially CD8 + cells, potentially impacting immune function.

Background and objectives
Vasovagal reactions (VVR) are the most common adverse reactions in blood donation. This study aimed to provide and analyze the data of the regional hemovigilance system in Chongqing, China from 2020 to 2022, report the prevalence and explore the risk factors of VVR.
Materials and methods
R software (version 4.2.3) was used for all statistical analyses. Frequency and composition rates were used to describe the data of total donation, as well as data on the different types of ADR. The Chi-square test was used to analyze risk factors for VVR and inter-group comparisons of VVR stratified by gender (female/male), age (18–22; 23–29; 30–39; 40–49; 50–60) and season(Spring (Mar.-May.); Summer (Jun.-Aug.); Autumn (sep.-Nov.); Winter (Dec.-Feb.)).
Results
The reported incidence rate of VVR was 8.69‰ during whole blood donations and 1.02‰ during platelet-apheresis donations.The stratified analysis revealed that female donors aged 18–22 years old and 30–39 years old were reported to have lower VVR rates than male donors, oppositely, higher in females in 50–60 years old. Statistically significant differences in the incidence rate of VVR were observed between winter and summer, and between winter and spring in 18–49 years old. No seasonal variation was found in 50–60 years old.
Conclusions
The reported incidence rate of VVR related to blood donation was very low and varied from those calculated by other haemovigilance systems. The higher prevalence of VVR in young, first-time donors, college students, donating in mobile vehicles, males and in spring. Among first-time donors, the prevalence of VVR was higher in males than in females; and stratified analysis revealed there were seasonal variation and gender differences within a same age group.

Blood request form (BRF) stands as a pivotal document in ensuring safe and effective blood transfusions within healthcare settings. Incomplete or erroneous data on BRF can heighten risk of adverse reactions and compromise patient safety. Aim of study was to assess level of completion of BRFs by clinicians and to evaluate root cause analysis (RCA) of incompleteness of BRFs and factors leading to their rejection.
Materials and Methods
This prospective study was carried out from February 2024 to April 2024 on BRFs received in the blood centre. They were audited and RCA for factors leading to their incompleteness and rejection were analysed.
Results
Total number of BRFs received in blood centre was 14,468. 13,358 (92.3%) BRFs were accepted and 1,110 (7.7%) BRFs were rejected. 12,804 (95.85%) of accepted BRFs were incomplete. Weight was the most common missing parameter (89% {n = 11403}) while name of the requesting clinician was least common (2.5% {n-318}). 3.52% n = 510) BRFs were rejected due to mismatch in name and patient registration number on BRF and samples. 0.14% n = 21) BRFs were rejected due to hemolysed samples. RCA for incompleteness of BRFs showed that main reason was manpower (61–83%) while environment was least common (17–67%). RCA for rejection of BRFs showed that environment was most common cause (13.3–80.15%) while manpower was least common (9–19.85%).
Conclusion
Regular audits and personnel training, and quality assurance measures can help identify and address deficiencies in BRF completion to enhance patient safety and reduce incidence of transfusion-related errors and complications.

Introduction
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common inherited enzyme disorder in red blood cell (RBC). Due to the importance of G6PD enzyme as an antioxidant in RBC, we tried to investigate the oxidative damage in red cell concentrates (RCCs) prepared from donors with G6PD enzyme deficiency in comparison with healthy donors.
Material method
This cross-sectional study was conducted on 20 male donors. Ten of the donors had G6PD deficiency (as a case) and the others had normal enzyme activity (as a control). Biochemical and oxidative damage parameters were examined in RCCs prepared from two groups on days 0, 7, 14, 21, 28 and 35 of RCCs storage; data comparison was analyzed by SPSS statistical software.
Results
According to the result, lactate concentration increased significantly from the 7th day to the 35th day of RCC storage in G6PD-deficient donors compared to the control (P < 0.05). In addition, malondialdehyde (MDA) concentration in G6PD-deficient RCC showed a significant increase compared to the control in all days of storage (P < 0.05). Among the hematological parameters, mean corpuscular volume (MCV) and mean cell hemoglobin (MCH) increased significantly in all days of RCC storage in G6PD-deficient donors compared to the control (P < 0.05).
Conclusion
Our study showed that oxidative changes in G6PD-deficient donors were significantly increased compared to the healthy donors, which probably leads to RCC storage lesion and an increase in blood transfusion complications. Due to the high prevalence of G6PD enzyme deficiency in pandemic areas, it seems that enzyme screening should be included in donor screening programs.

Ten of the donors had G6PD deficiency (as a case) and the others had normal enzyme activity (as a control). Biochemical and oxidative damage parameters were examined in RCCs prepared from two groups on days 0, 7, 14, 21, 28 and 35 of RCCs storage; data comparison was analyzed by SPSS statistical software.</div></div><div><h3>Results</h3><div>According to the result, lactate concentration increased significantly from the 7th day to the 35th day of RCC storage in G6PD-deficient donors compared to the control (<em>P</em> < 0.05). In addition, malondialdehyde (MDA) concentration in G6PD-deficient RCC showed a significant increase compared to the control in all days of storage (<em>P</em> < 0.05). Among the hematological parameters, mean corpuscular volume (MCV) and mean cell hemoglobin (MCH) increased significantly in all days of RCC storage in G6PD-deficient donors compared to the control (<em>P</em> < 0.05).</div></div><div><h3>Conclusion</h3><div>Our study showed that oxidative changes in G6PD-deficient donors were significantly increased compared to the healthy donors, which probably leads to RCC storage lesion and an increase in blood transfusion complications. Due to the high prevalence of G6PD enzyme deficiency in pandemic areas, it seems that enzyme screening should be included in donor screening programs.</div></div>","PeriodicalId":23262,"journal":{"name":"Transfusion Clinique et Biologique","volume":"31 4","pages":"Pages 201-208"},"PeriodicalIF":1.4,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141984236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
