REVIEW

Urgency and emergency in general, and even more in the pediatric setting, remain a thematic debate not yet fully resolved. The decision to undergo a pediatric patient to an invasive treatment not free from potentially serious side effects like an apheresis procedure should be weighted with great attention. At the moment there is no unanimous consensus about the clinical pictures in which an urgency procedure in pediatrics is indicated. Each center acts according to its own experience and not infrequently to its own fears...

Clinical practice and related diagnostic, development and research [DDR] strategies in pediatric transfusion and transplantation cover a broad range of multidisciplinary studies, performed by many professionals involved in this most challenging clinical field [1]. This commentary on the current position and future perspectives in pediatric transfusion field is aimed to highlight major unresolved transfusion complications in pediatric patients, namely red blood cell and platelet alloimmunisation, and new ones such as nosocomial infection, thrombosis and multi-organ failure...

REVIEW
Raymond P Goodrich, Jerard Segatchian
Pediatric patients requiring transfusion constitute one of the most challenging areas of transfusion practice. Due to the limitations posed by their particular physiological conditions they routinely require specialized component support and more personalised transfusion care than what is routinely utilized in the care of adult patients. Pediatric patients, unlike many adult patients requiring transfusion support, also generally have significant lifespans post-transfusion. This combined with the possibility of long term consequences to adverse events related to transfusion such as infection or change in immunological status drives the need to continue to use improved blood components in the transfusion support of pediatric patients...

Red cell transfusions are amongst the most common therapeutic procedures in seriously ill children, particularly in the inpatient setting. This is despite the fact that there is no evidence base for most clinical settings, with the exception of patients with hemoglobinopathies, particularly thalassemia and sickle cell anemia. Obviously exsanguinating hemorrhage and life threatening anemia are urgent indications for which no other therapeutic approach is currently available. Most transfusions are, however, given prophylactically to prevent the complications of hypoxia or hemodynamic stability, based upon expert opinion and a faith in the oxygen carrying capacity and beneficial hemodynamic properties of transfused red cells...

Artificial Intelligence (AI) reflects the intelligence exhibited by machines and software. It is a highly desirable academic field of many current fields of studies. Leading AI researchers describe the field as "the study and design of intelligent agents". McCarthy invented this term in 1955 and defined it as "the science and engineering of making intelligent machines". The central goals of AI research are reasoning, knowledge, planning, learning, natural language processing (communication), perception and the ability to move and manipulate objects...

Hematopoietic stem cell transplantation is a curative treatment for many hematologic malignancies with its most important side effect being graft-versus-host disease (GVHD). Herein, we present a 3.5 year-old male with weight of 9.8 kg with acute GVHD (grade IV gastrointestinal and cutaneous) who did not respond to the first line therapies (corticosteroids). Thus, the patient was a candidate for extracorporeal photochemotherapy (ECP). Due to the hyperbilirubinemia, two sessions of ECP every week as well as one session of plasmapheresis 24 h before each ECP session were performed (Spectra™ Optia® apheresis system)...

Pediatric peripheral blood stem cell collection (PBSC) is challenging because it has potentially more side effects than in adults due to the small body mass and unique physiology of children. The extracorporeal volume of the cell separator device, poor venous access and metabolic complications due to citrate toxicity are the main problems to face during PBSC collection. These aspects are more relevant in very low body weight (BW) children of 20 kg or lower. An efficient, experienced and well-prepared team of pediatricians, apheresis physicians and nurses, and physicians involved in CVC positioning is crucial to performing a safe PBSC collection...

Statistical process control (SPC) is closely related to good quality control practices in the manufacturing process. One of the primary goals is to detect unnatural patterns, allowing the production service to control the conformity of the blood components produced. Despite being recommended by national and international standards, its exercise is not uniform, and sometimes the methodology used is misinterpreted as SPC. When the input data has a Gaussian distribution, control charts for variables are proposed...

BACKGROUND: The Spectra Optia continuous mononuclear cell (CMNC) program is newly available, and herein validated in a single-center cohort enriched with AL amyloidosis patients to collect a target CD34+ yield of 2.5 × 106 cells/kg within 2 days. METHODS: Consecutive autologous transplant patients in 2016 are included. Patients undergo leukapheresis with Optia CMNC and Spectra v4.7 over a 2-day cycle. Data collection includes collection efficiency, adverse events and engraftment kinetics...

Hemophilia is a hereditary disease with impaired blood coagulation due to a genetic deficiency of blood coagulation factors. The development of inhibitors further complicates the course of the disease and management. The case is here reported of a haemophilia patient who presented with coexisting development of high titer inhibitor with Gastrointestinal Stromal Tumor (GIST) diagnosis and was admitted with upper gastrointestinal system bleeding. The patient had no prior history of inhibitor presence. During all procedures including surgery, excellent hemostasis was achieved with rFVIIa treatment and no hemorrhagic complication was observed...

BACKGROUND: Recently, novel protocol utilizing Continuous Mononuclear Cell Collection (cMNC) have been introduced for leukapheresis. We compared the efficacy of cMNC with an older protocol - mononuclear cell collection (MNC) for CD34+ cell collection in unrelated donors with negative stem cell collection predictors. MATERIAL AND METHODS: Retrospective data from a series of 258 consecutive unrelated hematopoietic stem cell donors was included in this single-center study (80 donors collected with cMNC and 178 with MNC)...

Antithrombin [AT] is the main inhibitor for activated plasma coagulation serine esterases, inhibiting thrombin, Factors Xa and IXa, but also Factors XIIa, XIa, VIIa, kallicrein, and plasmin. Its activity is highly enhanced by heparin, through binding to the pentasaccharide sequences, for inhibition of all coagulation proteases, except thrombin, which inhibition requires its additional binding to the heparin polysaccharide chain. However, AT is the major inhibitor of thrombin in the blood circulation. Congenital or acquired deficiencies of AT expose affected patients to an increased risk of developing unprovoked and recurrent thrombo-embolic diseases...

Iron deficiency anemia is one of the widespread forms of anemia worldwide with important consequences on public health in general and in the management of the hospital blood supply in particular. In this context we decided to "de novo"organize a new hospital service specifically dedicated to iron therapy to correctly diagnose iron deficiency anemia and support patients with the latest generation of i.v. iron formulation. We describe the organizational and educational solutions we adopted to start the new service...

Hematopoietic stem cells may be obtained by collection of bone marrow, mobilization and collection of peripheral blood stem cells or umbilical cord blood. Transplantation of peripheral blood hematopoietic cells has increased due to faster engraftment and practicability in both the related, unrelated or haploidentical setting. We reviewed the question of which stem cell source - bone marrow (BM) or peripheral blood (PBSC) - is the most suitable for individuals undergoing haploidentical stem cell transplantation...
