The transfusion of red blood cells (RBCs) is a common intervention in intensive care unit (ICU) patients, yet the benefits are far from clear in patients with moderate anemia (eg, hemoglobin (Hb) levels of 7-10 g/dL). Determining which of these patients benefit, and how to even define benefit, from transfusion is challenging. As the intended physiological benefit underpinning RBC transfusion is to improve tissue oxygenation, several studies utilizing a wide range of assessment techniques have attempted to study the effects of transfusion on tissue oxygenation and microcirculatory function...

Iron is an essential nutrient element for human, but has potential toxicity. Under physiological conditions, the processes of iron absorption, transportation, cellular uptake and utilization, storage, release, excretion as well as regulation of iron metabolism maintain the iron homeostasis. However under pathological conditions, the iron metabolism changes and is associated with the pathological states. In order to realize the relationship between the critical illness status and the iron metabolism, we start with an analysis of the basic processes of iron metabolism in human and the toxicity of iron, followed by summary on the alteration of iron metabolism in the settings of pathological conditions, such as inflammation, infection and anemia, which often occur in critical illness...

INTRODUCTION: Preoperative anemia and high red cell distribution width (RDW) are associated with higher perioperative mortality. Conditions with high RDW levels can be categorized by mean corpuscular volume (MCV). The relationship between RDW, anemia and MCV may explain causality between high RDW levels and outcomes. We aim to establish the prevalence of preoperative anemia and distribution of RDW and MCV among pre-surgical patients in Singapore. In addition, we aim to investigate the association between preoperative anemia, RDW and MCV levels with one-year mortality after surgery...

The most frequent germline mutations responsible for non syndromic congenital sideroblastic anemia are identified in ALAS2 and SLC25A38 genes. Iron overload is a key issue and optimal chelation therapy should be used to limit its adverse effects on the development of children. Our multicentre retrospective descriptive study compared the strategies for diagnosis and management of congenital sideroblastic anemia during the follow-up of six patients with an ALAS2 mutation and seven patients with an SLC25A38 mutation...

Mauricio Seguel, Nicole Gottdenker
Hookworms are blood-feeding nematodes that parasitize the alimentary system of mammals. Despite their high pathogenic potential, little is known about their diversity and impact in wildlife populations. We conducted a systematic review of the literature on hookworm infections of wildlife and analyzed 218 studies qualitative and quantitatively. At least 68 hookworm species have been described in 9 orders, 24 families, and 111 species of wild mammals. Black bears, red foxes, and bobcats harbored the highest diversity of hookworm species and Ancylostoma pluridentatum, A...

Non-ST elevation-acute coronary syndrome (NSTE-ACS) includes NSTE myocardial infarction and unstable angina. This patient population forms approximately two-thirds of all hospital admissions for ACS in the United States each year and is associated with an in-hospital mortality of 5%. NSTE-ACS is primarily due to an acute change in the supply and demand balance of coronary perfusion and myocardial oxygen consumption, because of the significant coronary artery obstruction presenting as plaque rupture or erosion...
