BACKGROUND: Massive transfusion protocols (MTPs) have been adopted in many hospitals, and they may improve outcomes, as well as decrease the number of blood products transfused. However, there are no specific guidelines regarding the number and types of products that should be included in these protocols. MTPs may vary from hospital to hospital. METHODS: A short, web-based survey was sent to blood bank medical directors at academic institutions to learn details about MTPs...

Advanced therapy medicinal products (ATMPs) represent the current pinnacle of 'patient-specific medicines' and will change the nature of medicine in the near future. They fall into three categories; somatic cell-therapy products, gene therapy products and cells or tissues for regenerative medicine, which are termed 'tissue engineered' products. The term also incorporates 'combination products' where a human cell or tissue is combined with a medical device. Plainly, many of these new medicines share similarities with conventional haematological stem cell transplant products and donor lymphocyte infusions as well as solid organ grafts and yet ATMPs are regulated as medicines and their development has remained predominantly in academic settings and within specialist centres...

Although the Model for End-Stage Liver Disease (MELD) score has been used to evaluate mortality of patients on the waiting list for liver transplantation, it has not established if it correlates with post-liver transplantation prognosis. The aim of this study is to assess if there is a relationship between pretransplantation MELD and post-transplantation results, especially regarding 30-day post-LT survival rates. We analyzed data from 172 patients who underwent deceased-donor liver transplantation between February 2013 and May 2015 in a single center...

We aimed to evaluate whether blood conservation strategies including intraoperative autologous donation (IAD) could reduce perioperative blood transfusion for patients undergoing cardiac valve replacement including mitral valve replacement, aortic valve replacement (AVR), and double valve replacement (DVR).A total of 726 patients were studied over a 3-year period (2011-2013) after the implementation of IAD and were compared with 919 patients during the previous 36-month period (January 2008-December 2010). The method of small-volume retrograde autologous priming, strict blood transfusion standard together with IAD constituted a progressive blood-saving strategy...

Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells represent an ideal source for in vitro modeling of erythropoiesis and a potential alternative source for red blood cell transfusions. However, iPS cell-derived erythroid cells predominantly produce ε- and γ-globin without β-globin production. We recently demonstrated that ES cell-derived sacs (ES sacs), known to express hemangioblast markers, allow for efficient erythroid cell generation with β-globin production. In this study, we generated several iPS cell lines derived from bone marrow stromal cells (MSCs) and peripheral blood erythroid progenitors (EPs) from sickle cell disease patients, and evaluated hematopoietic stem/progenitor cell (HSPC) generation after iPS sac induction as well as subsequent erythroid differentiation...

BACKGROUND: The majority of allogeneic transfusions occur in the perioperative setting, especially during cardiac surgery. In addition to the economic implications, there is emerging evidence that blood transfusion may increase both morbidity and mortality. Acute normovolemic hemodilution (ANH) may limit the need for blood products. OBJECTIVES: The primary objective of this study was to determine if the method of blood collection (syringe or bag) during the ANH process impacted the platelet count and function...

BACKGROUND: Zika virus (ZIKV) is an emerging mosquito-borne Flavivirus of major public health concern. The potential for ZIKV transmission by blood transfusion has been demonstrated; however, inactivation or removal of ZIKV during the manufacture of plasma-derived medicinal products has not been specifically investigated. STUDY DESIGN AND METHODS: Inactivation of ZIKV by pasteurization and solvent/detergent (S/D) treatment was investigated by spiking high-titer ZIKV stocks into human serum albumin and applying either heat or adding different mixtures of S/D reagents and assaying for infectious virus particles...

OBJECTIVE: The aim of the study was to determine the frequency and reasons for donor deferral prior to the blood donation process in our population. BACKGROUND: Transfusion is an irreversible event that carries potential risks as well as benefits to the recipient. Therefore, donor selection prior to blood donation is one of the most important steps in ensuring the safety of blood and blood products. METHODS: A cross-sectional study was carried out at the blood bank department in our hospital from January 2012 to December 2014...

BACKGROUND/OBJECTIVES: The safety of administering uncrossmatched, group O, cold-stored, whole blood (cWB) during civilian trauma resuscitation was evaluated. METHODS/MATERIALS: Male trauma patients with haemorrhage-induced hypotension who received leuko-reduced uncrossmatched group O+, low titer (<50) anti-A and -B, platelet-replete cWB during initial resuscitation were included. The biochemical markers of haemolysis (lactate dehydrogenase, total bilirubin, haptoglobin, creatinine, serum potassium) were measured on the day of cWB receipt (day 0), and over the next 2 days, reports of transfusion reactions and total blood product administration in first 24 h of admission were recorded...

Cardiac surgery accounts for between 15% and 20% of all blood product utilization in the United States. A body of literature suggests that patients who are exposed to even small quantities of blood have an increased risk of morbidity and mortality, even after adjusting for pre-operative risk. Despite this body of literature supporting a restrictive blood management strategy, wide variability in transfusion rates exist across institutions. Recent blood management guidelines have shed light on a number of potentially promising blood management strategies, including acute normovolemic hemodilution (ANH) and retrograde autologous priming (RAP)...

Trauma is a leading cause of death and disability worldwide, in civilian environments and on the battlefield. Trauma-induced haemorrhage is the principal cause of potentially preventable death, which is generally attributable to a combination of vascular injury and coagulopathy. Survival rates following severe traumatic injury have increased due to advanced trauma management initiatives and treatment protocols, influenced by lessons learned from recent conflicts in Iraq and Afghanistan. The use of tourniquets and intraosseous needles, early blood and blood product transfusion, administration of tranexamic acid in pre-hospital settings, and consultant-led damage control resuscitation incorporating damage control surgery have all played their part...

BACKGROUND: Several studies have raised concerns that future demand for blood products may not be met. The ageing of the general population and the fact that a large proportion of blood products is transfused to elderly patients has been identified as an important driver of blood shortages. The aim of this study was to collect, for the first time, nationally representative data regarding blood donors and transfusion recipients in order to predict the future evolution of blood donations and red blood cell (RBC) use in Switzerland between 2014 and 2035...

BACKGROUND: Patients with end-stage liver disease (ESLD) are assumed to be at high risk of bleeding when undergoing any kind of invasive intervention (any kind of operation, including transplantation or minimally invasive interventions). Both bleeding and thrombosis are associated with a poor outcome. METHODS: A selective literature research was conducted with the following key words: 'cirrhosis', 'coagulation', 'bleeding', 'INR' (international normalized ratio), 'aPTT' (activated partial thromboplastin time), and 'thrombocytopenia'...

BACKGROUND: Transfusion of red blood cells (RBCs) is associated with adverse outcome, but the causative factor is unknown. Extracellular vesicles (EVs) have pro-inflammatory properties. We hypothesized that EVs released from both fresh and stored RBC products can induce a host inflammatory response in a dose-dependent manner. METHODS: Whole blood was incubated with supernatant from RBC units stored for different time periods, either containing (different numbers of) EVs or depleted from EVs...

BACKGROUND: The Australian and New Zealand (ANZ) Massive Transfusion (MT) Registry (MTR) has been established to improve the quality of care of patients with critical bleeding (CB) requiring MT (≥ 5 units red blood cells (RBC) over 4 h). The MTR is providing data to: (1) improve the evidence base for transfusion practice by systematically collecting data on transfusion practice and clinical outcomes; (2) monitor variations in practice and provide an opportunity for benchmarking, and feedback on practice/blood product use; (3) inform blood supply planning, inventory management and development of future clinical trials; and (4) measure and enhance translation of evidence into policy and patient blood management guidelines...

BACKGROUND: We aimed to quantify and predict variability that exists in resource utilization after pancreaticoduodenectomy and determine how such variability impacts postoperative outcomes. METHODS: The University HealthSystems Consortium database was queried for all pancreaticoduodenectomies performed between 2011-2013 (n = 9,737). A composite resource utilization score was created using z-scores of 8 clinically significant postoperative care delivery variables including number of laboratory tests, imaging tests, computed tomographic scans, days on antibiotics, anticoagulation, antiemetics, promotility agents, and total number of blood products transfused per patient...

The association of blood transfusions with GS after pediatric KTx is unclear. We retrospectively analyzed blood transfusions post-KTx and subsequent outcomes. Between 1984 and 2013, 482 children (<18 years of age) underwent KTx at our center. Recipient demographics, outcomes and transfusion data were collected. Cox regression with post-KTx blood transfusion as a time-dependent covariate was performed to model the impact of blood transfusion on outcomes. Of the 208 (44%) that were transfused, 39% had transfusion <1 month post-KTx; 48% >12 months...
