BACKGROUND: Acute mesenteric ischemia (AMI) is a rare but severe complication after cardiac surgery. However, AMI is likely to be more frequent in the subgroup of patients presenting with multiple organ failure after a cardiac surgery. The primary objective of this study was to identify AMI risk factors among patients requiring intensive care unit (ICU) admission after cardiac surgery. METHODS: Retrospective observational study of all the patients requiring admission to two ICUs in a large university hospital after a cardiac surgery procedure...

BACKGROUND: Endovascular therapy is well studied in atraumatic conditions; and there appears to be a growing interest in its application to traumatic injuries. The objective of this study is to compare open and endovascular techniques in the management of peripheral arterial trauma. METHODS: This is a retrospective review of patients admitted to a Level I Trauma Center sustaining injuries to the subclavian, axillary, superficial femoral, and popliteal arteries. Demographics, surgical interventions, complications, and clinical outcomes were evaluated in patients requiring open or endovascular repair between 2009 and 2015...

Coagulopathy is common in intensive care units (ICUs). Many physiologic derangements lead to dysfunctional hemostasis; these may be either congenital or acquired. The most devastating outcome of coagulopathy in the critically ill is major bleeding, defined by transfusion requirement, hemodynamic instability, or intracranial hemorrhage. ICU coagulopathy often poses complex management dilemmas, as bleeding risk must be tempered with thrombotic potential. Coagulopathy associated with intracranial hemorrhage bears directly on prognosis and outcome...

OBJECTIVE: To determine the epidemiology of bleeding in critically ill children. STUDY DESIGN: We conducted a cohort study of children <18 years old admitted to the pediatric intensive care unit for >24 hours and without clinically relevant bleed (CRB) on admission. CRB was defined as resulting in severe physiologic derangements, occurring at a critical site or requiring major therapeutic interventions. Using a novel bleeding assessment tool that we developed, characteristics of the CRB were abstracted from the medical records independently and in duplicate...

OBJECTIVES: Impaired oxygen delivery due to reduced cerebral blood flow is the hallmark of delayed cerebral ischemia following subarachnoid hemorrhage. Since anemia reduces arterial oxygen content, it further threatens oxygen delivery increasing the risk of cerebral infarction. Thus, subarachnoid hemorrhage may constitute an important exception to current restrictive transfusion practices, wherein raising hemoglobin could reduce the risk of ischemia in a critically hypoperfused organ...

BACKGROUND: Damage control laparotomy (DCL) is not well studied in the pediatric trauma population. The purpose of this study was to develop a surrogate definition of DCL compatible with national and administrative data sources so that the rate and outcomes of DCL in pediatric trauma patients could be determined. METHODS: Using the 2010-2014 National Trauma Data Bank, children ≤18 with an abdominal AIS ≥ 3 who underwent a laparotomy within 3 h of arrival were identified (n = 2989)...

BACKGROUND: Red blood cell transfusion is common in critically ill children after cardiac surgery. Since the threshold for hemoglobin (Hb) transfusion need is not well defined, the threshold Hb level at which dependent critical oxygen uptake-to-delivery (VO2-DO2) status compensation is uncertain. OBJECTIVES: To assess the effects of blood transfusion on the oxygen extraction ratio (O2ER) and central venous oxygen saturation (ScvO2) to identify a critical O2ER value that could help us determine the critical need for blood transfusion...

BACKGROUND: There is no standard method to ensure survival of random-pattern skin flaps. The authors developed a rat anemia model to observe survival of random-pattern skin flaps after blood transfusion and hemodilution. METHODS: Anemia was induced by withdrawal of 35 percent blood volume followed by compensation with the same amount of blood (blood transfusion model) or plasma equivalent (normovolemic hemodilution). Control rats were subjected to a sham procedure...

The administration of cisplatin (CDDP) may influence trace metal concentrations in body fluids. In order to test this hypothesis, the blood concentrations of trace metals were determined during the present study in eight Japanese esophageal and lung cancer patients receiving CDDP-based chemotherapy. The levels of manganese, iron (Fe), cobalt, copper, zinc (Zn), platinum and lead in the plasma were determined by inductively coupled plasma-mass spectrometry. In addition, the serum levels of Fe, transferrin and ferritin were evaluated...

Deep vein thrombosis (DVT) with its major complication, pulmonary embolism, is a global health problem. Mechanisms of DVT remain incompletely understood. Platelets play a role in DVT but the impact of specific platelet receptors remains unclear. Platelet C-type lectin-like receptor 2 (CLEC-2) is known to maintain the physiological state of blood vasculature under inflammatory conditions. DVT is a thromboinflammatory disorder developing largely as sterile inflammation in the vessel wall. We hypothesized therefore that CLEC-2 might play a role in DVT...

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...

OBJECTIVE: To assess the potential utility of a novel non-invasive muscle oxygen measurement to determine the presence of muscle hypoxia in patients with anaemia. BACKGROUND: Recent assessment of the risk/benefit ratio of blood transfusion has led to clinical strategies optimising transfusion decisions. These decisions are primarily based on haematocrit (Hct) but not oxygen delivery, the primary function of red blood cells (RBCs). We hypothesised that muscle oxygenation (MOx) would correlate with Hct in patients with anaemia and may be a physiologically relevant determinant of the transfusion threshold...

Dimethylsulfoxide (DMSO) is a solvent which protects the structure of allografts during the cryopreservation and thawing process. However, several toxic effects of DMSO in patients after transplantation of cryopreserved allografts have been described. The aim of this study is to determine the residual DMSO in the cardiovascular allografts after thawing and preparation of cryopreserved allografts for clinical application following guidelines of the European Pharmacopoeia for DMSO detection. Four types of EHB allografts (aortic valve-AV, pulmonary valve-PV, descending thoracic aorta-DA, and femoral artery-FA) are cryopreserved using as cryoprotecting solution a 10% of DMSO in medium 199...

BACKGROUND: Platelets are commonly transfused to critically ill patients. Reports suggest an association between platelet transfusion and infection. However, there is no large study to have determined whether platelet transfusion in critically ill patients is associated with hospital-acquired infection. METHODS: We conducted a multi-centre study using prospectively maintained databases of two large academic intensive care units (ICUs) in Australia. Characteristics of patients who received platelets in ICUs between 2008 and 2014 were compared to those of patients who did not receive platelets...

REVIEW
Laura Percy, Diana Mansour, Ian Fraser
Iron deficiency (ID) is the most common micronutrient deficiency worldwide with >20% of women experiencing it during their reproductive lives. Hepcidin, a peptide hormone mostly produced by the liver, controls the absorption and regulation of iron. Understanding iron metabolism is pivotal in the successful management of ID and iron deficiency anaemia (IDA) using oral preparations, parenteral iron or blood transfusion. Oral preparations vary in their iron content and can result in gastrointestinal side effects...

Jinlin Jiang, Chen-Yuan Kao, Eleftherios T Papoutsakis
Megakaryocytic microparticles (MkMPs), the most abundant MPs in circulation, can induce the differentiation of hematopoietic stem and progenitor cells (HSPCs) into functional megakaryocytes. This MkMP capability could be explored for applications in transfusion medicine but also for delivery of nucleic acids and other molecules to HSPCs for targeted molecular therapy. Understanding how MkMPs target, deliver cargo and alter the fate of HSPCs is important for exploring such applications. We show that MkMPs, which are distinct from Mk exosomes (MkExos), target HSPCs with high specificity since they have no effect on other ontologically or physiologically related cells, namely mesenchymal stem cells, endothelial cells or granulocytes...

BACKGROUND: The incidence of dengue hemorrhagic fever is increasing among the adult population living in endemic areas. The disease carries a 0.73% fatality rate for the general population, but what happens when the disease strikes a special subpopulation group, the obstetrics? Perhaps the important question specific to this special subpopulation revolves around the right time and mode of delivery under severe coagulopathy and plasma leakage in conditions of imminent delivery. CASE PRESENTATION: A 24-year-old primigravid Sundanese woman presented to our intensive care unit due to acute pulmonary edema secondary to massive plasma leakage caused by severe dengue...

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...
