BACKGROUND AND OBJECTIVES: Recently, thalassemia has been introduced as a chronic disease. In spite of prolonging life in thalassemia patients, the quality of their life has not significantly improved. One of the challenges that makes their quality of life poor is alloimmunisation which causes several complications to patients by restricting their options. Some individuals are more susceptible to developing an alloantibody than others. They are categorised as responders and non-responders...

BACKGROUND: Solid renal masses are increasingly treated with nephron-sparing surgery. As in other uro-oncological surgical techniques, minimally invasive and robotic-assisted techniques are becoming increasingly popular. OBJECTIVES: The perioperative results from minimally invasive nephron-sparing surgery versus open surgery were retrospectively compared. MATERIALS AND METHODS: In our single center retrospective study, all patients who underwent nephron-sparing tumor excision between 2006 and 2016 were divided into two groups (group O = open approach and group M = minimally invasive approach)...

EDITORIAL
Andrew W Yen
Blood transfusion practices for acute upper gastrointestinal hemorrhage have changed over time. Restrictive strategies, which gave way to more liberal approaches for the greater part of the 20th century, have again gained traction as emerging research suggests restricting transfusion is associated with similar, or possibly better outcomes in UGI bleeding. In a large, retrospective cohort study from an integrated health care system in Taiwan, Chen, et al., report the association between early blood transfusion and clinical outcomes in patients presenting to the emergency department with UGI bleeding, and these findings are discussed in the context of current knowledge and practice...

Non-variceal upper gastrointestinal bleeding remains an important emergency condition, leading to significant morbidity and mortality. As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages...

PURPOSE: The efficacy and thrombogenicity of transdermal estradiol in the management of refractory uremic bleeding in adults are examined. SUMMARY: Platelet dysfunction from chronic kidney disease may induce uremic bleeding. This type of bleeding may involve the skin, oral and nasal mucosa, gingivae, respiratory system, and gastrointestinal or urinary tract. While the mainstay of treatment for uremic bleeding primarily involves dialysis and use of prohemostatic agents such as desmopressin and erythropoiesis-stimulating agents, certain patients may experience bleeding refractory to these interventions...

Chemically modified hemoglobin (Hb)-based oxygen carriers are promising oxygen replacement therapeutics however their potential renal effects are not fully understood. Using a guinea pig exchange transfusion model, we examined the effects of glutaraldehyde-polymerized bovine hemoglobin (HbG) on the permeability and integrity of the glomerular filtration barrier (GFB), which is comprised of podocytes, fenestrated endothelium, and the glomerular basement membrane. HbG induced marked proteinuria characterized in part by the loss of high molecular weight proteins, including albumin, immunoglobulin, and transferrin, at 4 and 12 hours post-infusion that resolved by 72 hours...

BACKGROUND: Refrigerated red blood cell (RBC) storage results in the progressive accumulation of biochemical and morphological alterations collectively referred to as the storage lesion. Storage-induced metabolic alterations can be in part reversed by rejuvenation practices. However, rejuvenation requires an incubation step of RBCs for 1 hour at 37°C, limiting the practicality of providing "on-demand," rejuvenated RBCs. We tested the hypothesis that the addition of rejuvenation solution early in storage as an adjunct additive solution would prevent-in a time window consistent with the average age of units transfused to sickle cell recipients at Duke (15 days)-many of the adverse biochemical changes that can be reversed via standard rejuvenation, while obviating the incubation step...

BACKGROUND: The safety of platelet concentrates (PCs) is a major concern in transfusion medicine due to contamination mainly with skin Gram-positive bacteria. The predominant contaminant, Staphylococcus epidermidis, forms bacterial cell aggregates (biofilms) in PCs posing a safety risk for transfusion patients. Combinations of synthetic antimicrobial peptides (AMPs) have demonstrated bactericidal activity in PCs. Herein, we have evaluated the ability of a mix of AMPs to inhibit biofilm formation and/or eradicate S...

A nanoparticle-based electrochemical sandwich immunoassay was developed for bacteria detection in platelet concentrates. For the assay, magnetic beads were functionalized with antibodies to allow the specific capture of bacteria from the complex matrix, and innovative methylene blue-DNA/nanoparticle assemblies provided the electrochemical response for amplified detection. This nanoparticular system was designed as a temperature-sensitive nano-tool for electrochemical detection. First, oligonucleotide-functionalized nanoparticles were obtained by direct synthesis of the DNA strands on the nanoparticle surface using an automated oligonucleotide synthesizer...

Olivier Garraud, Jean-Daniel Tissot
Blood transfusion is made possible because, in most countries and organizations, altruistic individuals voluntarily, anonymously, and generously donate (without compensation) either whole blood or separated components that are then processed and distributed by professionals, prior to being allocated to recipients in need. Being part of modern medicine, blood transfusion uses so-called standard blood components when relative to cellular fractions and fresh plasma. However, as will be discussed in this paper, strictly speaking, such so-called labile blood components are not completely standard...
