BACKGROUND: Transarterial embolization (TAE) is a therapeutic option for patients with a high risk of recurrent bleeding after endoscopic haemostasis. The aim of our prospective study was a preliminary assessment of the safety, efficacy, and clinical outcomes following preventive TAE in patients with non-variceal acute upper gastrointestinal bleeding (NVUGIB) with a high risk of recurrent bleeding after endoscopic haemostasis. METHODS: Preventive visceral angiography and TAE were performed after endoscopic haemostasis on patients with NVUGIB who were at a high risk of recurrent bleeding (PE+ group)...

Nearly 21 million components of blood and whole blood and transfused annually in the United States, while on average only 13.6 million units of blood are donated. As the demand for Red Blood Cells (RBCs) continues to increase due to the aging population, this deficit will be more significant. Despite decades of research to develop hemoglobin (Hb) based oxygen (O2) carriers (HBOCs) as RBC substitutes, there are no products approved for clinical use. Lumbricus terrestris erythrocruorin (LtEc) is the large acellular O2 carrying protein complex found in the earthworm Lumbricus terrestris...

BACKGROUND AND OBJECTIVES: The accumulation of non-polar lipids arachidonic acid, 5-hydroxyeicosatetraenoic acid (HETE), 12-HETE and 15-HETE during storage of transfusion products may play a role in the onset of transfusion-related acute lung injury (TRALI), a syndrome of respiratory distress after transfusion. MATERIALS AND METHODS: We investigated non-polar lipid accumulation in red blood cells (RBCs) stored for 42 days, plasma stored for 7 days at either 4 or 20°C and platelet (PLT) transfusion products stored for 7 days...

BACKGROUND: Conflicting results have been reported concerning the effect of platelet transfusion on several outcomes. The aim of this study was to assess the independent effect of a single early intraoperative platelet transfusion on bleeding and adverse outcomes in cardiac surgery patients. METHODS: For this observational study, 23,860 cardiac surgery patients were analyzed. Patients who received one early (shortly after cardiopulmonary bypass while still in the operating room) platelet transfusion, and no other transfusions, were defined as the intervention group...

Malaria, which is one of the three most important infectious diseases globally, is endemic in many areas of the world. Plasmodium falciparum is not endemic to Turkey but can be seen after travel to epidemic countries. Transfusion-related acute lung injury (TRALI) syndrome is a rare disease, which may develop following the transfusion of all types of blood products, including plasma. Here we describe a case of TRALI syndrome in a 29-year-old male, who presented with fever after 15 days of returning from a business trip to Burkina Faso...

Microparticles have been shown to shed from a variety of viable cells as a consequence of inflammatory processes, activation or physical stress. Seventy to 90% of circulating microparticles are thought to be platelet-derived. The content of microparticles in blood collected from normal blood donors is highly variable and transfers into the final blood component. Elevated microparticle content (MPC) in donor blood might indicate an asymptomatic clinical condition of the donor which might affect the transfusion recipient, particularly pediatric patients...

BACKGROUND: Thioredoxin (TRX), an endogenous anti-oxidant protein induced in inflammatory conditions, has been shown to increase in plasma and to be associated with outcome in septic patients. This biomarker has never been studied in a trauma setting. We hypothesized that TRX would be increased after trauma and associated with post-injury sepsis. METHODS: Single-centre prospective observational study conducted at the intensive care unit (ICU) at the Karolinska University Hospital, Stockholm, Sweden, a level-1 trauma centre...

BACKGROUND: The combined effects of balanced transfusion ratios and use of procoagulant and antifibrinolytic therapies on trauma-induced exsanguination are not known. The aim of this study was to investigate the combined effect of transfusion ratios, tranexamic acid and products containing fibrinogen on the outcome of injured patients with bleeding. METHODS: A prospective multicentre observational study was performed in six level 1 trauma centres. Injured patients who received at least 4 units of red blood cells (RBCs) were analysed and divided into groups receiving a low (less than 1 : 1) or high (1 or more : 1) ratio of plasma or platelets to RBCs, and in receipt or not of tranexamic acid or fibrinogen products (fibrinogen concentrates or cryoprecipitate)...

BACKGROUND: Blood product transfusion is the most commonly performed hospital procedure. Intraoperative blood product utilization varies between institutions and anesthesiologists. In the United States in 2011, nearly 4 million plasma units were transfused. METHODS: A retrospective analysis of intraoperative plasma ordering patterns and utilization (thawing and transfusing) was performed at a tertiary, academic hospital between January 2015 and March 2016. RESULTS: Over 15 months, 46,002 operative procedures were performed...

Patients with cirrhosis used to be associated with frequent use of blood components because of their complex disorder of hemostasis and bleeding complications. Recent findings have indicated that patients with cirrhosis have a state of "rebalanced" or even procoagulant hemostasis and have questioned the prophylactic use of plasma. To evaluate the current status of plasma use in patients with cirrhosis, we conducted a retrospective survey in 11 tertiary-care hospitals in China from September 1 to October 31, 2013...

Coagulopathy and severe bleeding are associated with high mortality. We evaluated haemostatic treatment guided by the functional viscoelastic haemostatic assays, thromboelastography or rotational thromboelastometry in bleeding patients. We searched for randomised, controlled trials irrespective of publication status, publication date, blinding status, outcomes published or language from date of inception to 5 January 2016 in six bibliographic databases. We included 17 trials (1493 participants), most involving cardiac surgery...

Trauma haemorrhage is a common reversible cause of death. Haemostatic resuscitation focuses on replacing the lost blood with transfusions equivalent to whole blood as early as possible. In Denmark, the optimal ratio for transfusions in massive bleeding is four packs of red blood cells, four packs of plasma and one pool of platelets (equal to ratio 1:1:1 in USA). Haemostatic resuscitation also includes a restricted use of crystalloids, early tranexamic acid, and a goal-directed transfusion therapy by using viscoelastic haemostatic assays to detect coagulopathy and the need for additional transfusions or pro-haemostatics...

BACKGROUND: Granulocyte transfusion (GTX) is a potential approach to correcting neutropenia and relieving the increased risk of infection in patients who are refractory to antibiotics. To mobilize enough granulocytes for transfusion, healthy donors are premedicated with granulocyte-colony-stimulating factor (G-CSF) and dexamethasone. Granulocytes have a short circulatory half-life. Consequently, patients need to receive GTX every other day to keep circulating granulocyte counts at an acceptable level...
