Background: Clinical blood resources are scarce and autologous blood transfusion for extracorporeal membrane oxygenation (ECMO) withdrawal is less studied.
Objectives: To assess the use of staged autotransfusion during ECMO decannulation.
Methods: The study included ECMO withdrawal patients. Patients in the autologous transfusion group underwent staged transfusion during ECMO withdrawal, while those in the control group received 2.0 units of allogeneic packed red blood cells (RBCs) to increase hemoglobin (Hb). Parameters such as Hb, hematocrit (Hct), adverse events, decannulation success rate, volume of allogeneic RBC transfusions, and transfusion costs were compared.
Results: A total of 82 Chinese patients were enrolled, with a mean age of 46 years, 27 were female, and the top three primary diagnoses were cardiac arrest, acute myocarditis, and severe pneumonia. There were 41 individuals in the autologous blood transfusion group and 41 in the control group. No significant differences were observed in Hb, Hct, adverse events, and the success rate for decannulation between the two groups (all P > 0.05). Compared with the control group, the volume of allogeneic RBC transfusions [0 (0∼1.50) U vs. 3.5 (1.88∼40) U, P < 0.001] and the total cost [130 (130∼390) Chinese Yuan (CNY) vs. 910 (487.50, 1040) CNY, P = 0.002] were lower in the autologous transfusion group.
Conclusion: In comparison with allogeneic RBC transfusion, staged autotransfusion during ECMO decannulation not only effectively maintained Hb levels but also reduced the requirement for allogeneic RBC transfusions. In addition, this approach decreased the associated costs and did not increase the risk of clinical adverse events.

Objectives: Identifying cardiac surgical patients at risk of requiring red blood cell (RBC) transfusion is crucial for optimizing their outcome. We critically appraised prognostic models preoperatively predicting perioperative exposure to RBC transfusion in adult cardiac surgery and summarized model performance.
Methods: Design: Systematic review and meta-analysis.

Exposure to allogenic red blood cells (RBCs), either through pregnancy or transfusion, can result in alloimmunization, which can lead to severe hemolytic transfusion reactions and pregnancy complications. Passively administered antibodies can be used to prevent alloimmunization, where steric hindrance of allogeneic epitopes has been postulated as one mechanism whereby antibody engagement may prevent RBC alloimmunization. However, the dynamics of antibody engagement on the RBC surface has remained difficult to study.

X-linked sideroblastic anemia (XLSA) is a congenital anemia caused by mutations in ALAS2, a gene responsible for heme synthesis. Treatments are limited to pyridoxine supplements and blood transfusions, offering no definitive cure except for allogeneic hematopoietic stem cell transplantation, only accessible to a subset of patients. The absence of a suitable animal model has hindered the development of gene therapy research for this disease.

Tacrolimus is widely recognized as an anti-rejection agent due to its immunosuppressive characteristics. It binds to the immunophilin FK506-binding protein (FKBP) and thus to calcineurin, and inhibits its activity. Tacrolimus' therapeutic concentration range in blood is narrow, and its pharmacokinetics are highly variable among individuals.
