Platelet concentrate (PC) transfusions are a lifesaving adjunct to control and prevent bleeding in cancer, hematologic, surgical, and trauma patients. Platelet concentrate availability and safety are limited by the development of platelet storage lesions (PSLs) and risk of bacterial contamination. Platelet storage lesions are a series of biochemical, structural, and functional changes that occur from blood collection to transfusion. Understanding of PSLs is key for devising interventions that prolong PC shelf life to improve PC access and wastage...

Autoimmune hemolytic anemia (AIHA) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT) associated with poor outcome. However, an optimal therapeutic approach is lacking. Between 2000 and 2015, 4099 allogeneic HSCT were performed in eight pediatric centers of the Grupo Español De Trasplante de Medula Osea en Niños (GETMON) and six adult centers of the Grupo Español de Trasplante Hematopoyetico (GETH). Sixty cases of AIHA were registered with a cumulative incidence of 1.5% occurring at a median of 6 months after HSCT...

Antigens of the Gerbich blood group system are expressed on glycophorin C (GPC) and glycophorin D (GPD), minor sialoglycoproteins of human erythrocytes. GPC and GPD help maintain erythrocyte shape of and contributes to the stability of its membrane. There are six high-prevalence Gerbich antigens: Ge2, Ge3, Ge4, GEPL (GE10), GEAT (GE11), GETI (GE12) and five low-prevalence Gerbich antigens: Wb (GE5), Lsa (GE6), Ana (GE7), Dha (GE8), GEIS (GE9). Some Gerbich antigens (Ge4, Wb, Dha , GEAT) are expressed only on GPC, two (Ge2, Ana ) are expressed only on GPD, while others (Ge3, Lsa , GEIS, GEPL, GETI) are expressed on both GPC and GPD...

Longer storage duration of red blood cell (RBC) units prior to transfusion has been associated with worse outcomes in observational studies. We performed a systematic review, including recently published randomized trials, to determine if storage age of RBCs is associated with mortality, morbidity or adverse events in patients. Searches were performed up to 21st July 2017 in Medline (OvidSP), 20 July in EMBASE (OvidSP) and June 2017 in Cochrane Library. Eligible studies were randomized controlled trials comparing transfusion of fresher or freshest available with older or standard issue RBCs...

Knowledge deficits of transfusion medicine are prevalent among learners and practicing physicians. In the past, the transfusion medicine community has thoughtfully defined the content of transfusion medicine curriculums through Transfusion Medicine Academic Award Group and The Academy of Clinical Laboratory Physicians and Scientists. The manner in which the curriculum should be delivered has been less carefully examined and defined. We completed an observational study in which we analyzed 3 different teaching techniques: in-person faculty-led simulation curriculum consisting of didactic session and simulation ("Simulation group"); hybrid education with a combination of online materials and short in-person simulation ("Hybrid group"); and online-only education module, which delivered the whole curricular content through a variety of online materials and videos ("Online-only group")...

REVIEW
Meaghan E Colling, Pavan K Bendapudi
Purpura fulminans (PF) is a highly thrombotic subtype of disseminated intravascular coagulation that can accompany severe bacterial, and more rarely, viral infections. PF is associated with an extremely high mortality rate, and patients often die of overwhelming multisystemic thrombosis rather than septic shock. Survivors typically experience amputation of involved extremities and significant scarring in affected areas. Despite the devastating clinical course associated with this hemostatic complication of infection, the mechanism of PF remains poorly understood...

Postoperative anemia is a common occurrence in surgical patients and leads to an increased risk for allogeneic blood transfusions. The efficacy of iron therapy in treating postoperative anemia has not been firmly established. The objective of this systematic review was to evaluate the efficacy of postoperative oral and intravenous (IV) iron therapy in increasing hemoglobin levels and improving patient outcomes following elective surgery. The databases Medline, EMBASE, CENTRAL, the Transfusion Evidence Library, and ClinicalTrials...

Tranexamic acid (TXA) is an effective hemostatic agent used for the reduction of blood loss and transfusion. However, the safety profile of TXA remains in question due to a potential increased risk of venous thromboembolism. By applying TXA topically as opposed to intravenously, systemic absorption may be reduced and unwanted side-effects mitigated. The objective of our review is to investigate the efficacy and safety of topically applied tranexamic acid compared to both placebo, and the intravenous administration...

Historical accounts of the earliest experiments in blood transfusion celebrate work done in France and England in 1667 to 1668. Less attention has been given to pioneering experiments conducted at the same period in Italy. We review records of the first blood transfusion experiments conducted in 17th century Italy. Using original source documents, we provide details of early experiments focusing on the identity of early researchers, their instruments, and techniques. Accounts of the period describe animal-to-animal, animal-to-human, and human-to-human transfusions...

Allergic transfusion reactions (ATRs) are the most common adverse reactions occurring during transfusion of blood components. Although most reactions are mild and involve cutaneous manifestations, severe ATRs including life-threatening anaphylaxis may also occur. The mechanisms of ATRs are largely unknown because they have not been well studied. One of the reasons for this may be the absence of a standard assay system for investigating these processes. Basophils and/or mast cells are key effector cells in immediate-type allergic reactions...

The impact of donor characteristics, red cell age, and red cell processing methods on recipient outcomes is an emerging area of research. Knowledge generated from exploring this transfusion continuum has the potential to change the way donors are selected and how donations are processed and stored with important clinical and operational impact. Recently, donor characteristics including age, gender, donation frequency, genetics, and ethnicity have been shown to affect product quality and possibly recipient outcomes...

Using the French Hemovigilance Network database from 2007 to 2013, we provide information on demographics, incidence, and risk factors of reported transfusion-related acute lung injury (TRALI) and possible TRALI, analyze TRALI mitigation efforts for fresh frozen plasma and platelet concentrates, and consider the impact of platelet additive solutions on TRALI incidence. We applied the Toronto consensus conference definitions for TRALI and possible TRALI. Two TRALI subgroups were considered: "antibody positive" when a donor has human leukocyte antigen (class I or II) and/or human neutrophil antigen antibodies and the recipient has cognate antigen, and "antibody negative" when immunological investigation is negative or not done...

Estimating blood demand to determine collection goals challenges many low-income countries. We sampled Tanzanian hospitals to estimate national blood demand. A representative sample based on probability proportional to size sampling of 42 of 273 (15%) Tanzanian transfusing hospitals was selected. Blood bank registers, patient medical records, and blood component disposition records were reviewed prospectively from June to September 2013 to determine the number of components requested and the number and proportion issued, not issued due to nonavailability, and not issued for other reasons...

Optimal dose, timing and ratio to red blood cells (RBC) of blood component therapy (fresh frozen plasma [FFP], platelets, cryoprecipitate or fibrinogen concentrate) to reduce morbidity and mortality in critically bleeding patients requiring massive transfusion is unknown. We performed a systematic review for randomized controlled trials (RCT) in MEDLINE, The Cochrane Library, Embase, CINAHL, PubMed the Transfusion Evidence Library and using multiple clinical trials registries to 21 February 2017. Sixteen RCTs were identified: six completed (five in adult trauma patients, one pediatric burn patients) and ten ongoing trials...

REVIEW
Jean Cy Wang
To ensure an adequate blood supply, blood collection agencies must design campaigns to recruit and maintain an active donor pool. Such campaigns generally appeal to altruism and humanitarianism, which donors most commonly cite as their reasons for donating. However, large donor registries and the widespread recruitment campaigns that sustain them did not become a necessity until the technology for the collection, storage, and transfusion of blood had advanced to a point that enabled the establishment of transfusion services that could provide large amounts of stored blood to meet high demands...

REVIEW
Nishith N Patel, Gavin J Murphy
Cardiac surgical patients are among the highest consumers of allogeneic red blood cells (RBCs) due to the prevalence of anemia and bleeding. Up until recently, there was a paucity of high-quality evidence informing transfusion decisions in this patient group which led to wide variability in transfusion decision making. The article reviews and critically analyzes the available evidence for RBC transfusion in cardiac surgery, focusing on trials of transfusion triggers and age of blood, and provides suggestions for future research...

REVIEW
Aryeh Shander, Mazyar Javidroozi, Gregg Lobel
Patient Blood Management underscores a fundamental shift from a product-centered approach to a patient-centric approach through timely application of evidence-based medical and surgical concepts designed to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss in an effort to improve patient outcome. In this concept, allogeneic blood transfusion is not viewed as the treatment of default for anemic patients, but one among many treatment modalities that should be weighed based on its merits-potentials risks and benefits-for the individual patient in the context of other alternatives...
