BACKGROUND: The Geriatric Trauma Outcome Score, GTOS (= [age] + [Injury Severity Score (ISS)x2.5] + 22 [if packed red blood cells (PRBC) transfused ≤24hrs of admission]), was developed and validated as a prognostic indicator for in-hospital mortality in elderly trauma patients. However, GTOS neither provides information regarding post-discharge outcomes, nor discriminates between patients dying with and without care restrictions. Isolating the latter, GTOS prediction performance was examined during admission and 1-year post-discharge in a mature European trauma registry...

OBJECTIVE: We aimed to identify the role of the enzyme acid sphingomyelinase in the aging of stored units of packed red blood cells (pRBCs) and subsequent lung inflammation after transfusion. SUMMARY BACKGROUND DATA: Large volume pRBC transfusions are associated with multiple adverse clinical sequelae, including lung inflammation. Microparticles are formed in stored pRBCs over time and have been shown to contribute to lung inflammation after transfusion. METHODS: Human and murine pRBCs were stored with or without amitriptyline, a functional inhibitor of acid sphingomyelinase, or obtained from acid sphingomyelinase-deficient mice, and lung inflammation was studied in mice receiving transfusions of pRBCs and microparticles isolated from these units...

OBJECTIVE: To evaluate the impact of transfused packed red blood cell (PRBC) age on perioperative morbidity among patients undergoing major gastrointestinal surgery. BACKGROUND: Patients undergoing major surgery often receive PRBC transfusions. The effect of PRBC age (ie, storage duration before transfusion) on perioperative surgical outcomes remains poorly defined. METHODS: In this study, 1365 patients were identified who underwent a hepato-pancreatic or colorectal resection and received ≥1 unit of PRBCs between 2009 and 2014 at the Johns Hopkins Hospital...

Amniotic fluid embolism (AFE) is an unusual cause of life threatening peri partum hemorrhage (PPH). AFE resuscitation is often associated with renal and respiratory insufficiency, and a coagulopathy similar to disseminated intravascular coagulation (DIC). Resuscitation requires immediate recognition and limited use of crystalloid. We present a case of PPH caused by AFE with resultant cardiac arrest, renal and respiratory failure, and DIC-like coagulopathy, whose successful resuscitation was guided by perfusionist-directed serial thromboelastography (TEG)...

OBJECTIVE: Little is known about the outcomes of aortic root operations that involve inducing hypothermic circulatory arrest for relatively extensive proximal aortic surgery. We attempted to identify predictors of postoperative hospital length of stay (LOS) and factors that affect postoperative recovery. METHODS: During 2006-2014, 247 of 265 patients (93.2%) with disease extending into the aortic arch survived aortic root operations (206 elective, 41 urgent/emergent) in which hypothermic circulatory arrest with moderate hypothermia was used...

BACKGROUND: Microparticles (MP) are submicron, phosphatidylserine (PS)-bearing lipid vesicles with physiologic and pathologic roles in coagulation and inflammation. Microparticles accumulate in packed RBC (pRBC) stored for transfusion, potentially increasing recipient morbidity. Historically, canine MP have been detected with the PS label annexin V in supernatant samples. Other detection methods are available but have not been evaluated in dogs. OBJECTIVES: The purpose of the study was to detect and enumerate MP in canine pRBC using annexin V, lactadherin, and bio-maleimide to compare label performance and assess microparticle accumulation under standard storage conditions...

BACKGROUND: Age remains a significant and unmodifiable risk factor for cardiovascular diseases, and an increasing number of patients older than 80 years of age undergo Coronary Artery Bypass Grafting (CABG). Old age is also an independent risk factor for postoperative complications. The aim of this study is to describe the population of patients 80 years of age or older who underwent CABG procedure and to assess the mortality rate and risk factors for in-hospital mortality. METHODS: A retrospective case-series study analyzing 388 consecutive patients aged 80 years of age or older who underwent isolated CABG procedure between 2010 and 2014 in the Department of Cardiovascular Surgery and Transplantology, John Paul II Hospital, Krakow...

During routine storage, packed red blood cells (PRBC) undergo biochemical and morphological changes including loss of red blood cell (RBC) membrane asymmetry and release of microparticles (MPs) bearing phosphatidylserine (PS), a procoagulant phospholipid. This study investigated the association between PRBC storage duration, MP profile and procoagulant activity. Leukodepleted PRBC-supernatant (PRBC-SN; n=13) was prepared at weekly intervals throughout storage. Phospholipid-dependent procoagulant activity, assessed using a factor X-activated clotting time (XACT) assay, decreased throughout storage (p<0...

AIM: To determine if packed red blood cell transfusions contribute to the development of parenteral nutrition associated liver disease. METHODS: A retrospective chart review of 49 premature infants on parenteral nutrition for > 30 d who received packed red blood cell (PRBC) transfusions was performed. Parenteral nutrition associated liver disease was primarily defined by direct bilirubin (db) > 2.0 mg/dL. A high transfusion cohort was defined as receiving > 75 mL packed red blood cells (the median value)...

Numerous observational studies appear to demonstrate an association between packed red blood cell (pRBC) transfusions and necrotizing enterocolitis (NEC). However, the limited numbers of randomized controlled trials (RCTs) do not support a causal relationship between pRBC transfusion and NEC. We sought to determine the quality of the evidence behind transfusion-associated necrotizing enterocolitis (TANEC), and to formulate a GRADE-based recommendation regarding transfusion practices to reduce the risk of TANEC...

: The degree of increase in haematocrit and equilibration time following packed red blood cell (PRBC) transfusion in neonates is not well studied. We evaluated change in haematocrit 15 min, 6 h and 24 h after PRBC transfusion in neonates and factors predicting this change. Among neonates receiving PRBC transfusion, we recorded pre-transfusion haematocrit and a priori identified putative variables affecting change in haematocrit following transfusion. The factors affecting change in haematocrit were analyzed by multiple linear regression analysis...

Current guidelines recommend adenosine diphosphate receptor inhibitors (ADPRi) be discontinued 5-7 days prior to cardiac surgery due to increased bleeding events, rates of re-exploration, and transfusions. However, the risks of left ventricular assist device (LVAD) implantation in patients taking an ADPRi have not previously been studied. We retrospectively identified 134 eligible patients with ischemic cardiomyopathy that underwent LVAD implantation between July 2009 and August 2013. The cohorts received an ADPRi ≤5 days of surgery (n = 25) versus >5 days prior or not at all (n = 109)...

BACKGROUND: Malaria antibody responses measured at delivery have been associated with protection from maternal anaemia and low birth weight deliveries. Whether malarial antibodies present in the first half of pregnancy may protect from these or other poor birth outcomes is unclear. To determine whether malaria antibodies in the first half of pregnancy predict pregnancy outcomes, antibodies were measured to a range of merozoite antigens and to antigens expressed on the surface of parasitized red blood cells (pRBCs) in plasma samples collected at 14-20 weeks of gestation from Malawian women...

BACKGROUND: Early excision of burn wounds is the standard approach for burns, but it is usually associated with the need of allogeneic blood transfusion. Our aim was to determine if intravenous administration of tranexamic acid (TXA) was able to reduce packed red blood cell (pRBC) transfusion requirements in burn patients. METHODS: We conducted a retrospective cohort study of 2 consecutive series of severely burned patients (≥ 20% total body surface are) admitted for primary burn surgery...

Hemoglobin-vesicles (HbV), encapsulating highly concentrated human hemoglobin in liposomes, were developed as a substitute for red blood cells (RBC) and their safety and efficacy in transfusion therapy has been confirmed in previous studies. Although HbV suspensions are structurally and physicochemically stabile for least 1-year at room temperature, based on in vitro experiments, the issue of whether the use of long-term stored HbV after a massive hemorrhage can be effective in resuscitations without adverse, post-transfusion effects remains to be clarified...
