Position statement on the management of pregnancy in sickle cell disease.

Sickle cell disease (SCD) is a hereditary haemoglobinopathy which causes multi-organ dysfunction. Pregnancies in SCD are high risk with significant maternal and fetal morbidity and mortality, including vaso-occlusive crises, thrombosis, anaemia, placental insufficiency, fetal growth restriction, preterm birth and medication effects. High level evidence on this topic is lacking.

Invasive fungal disease and antifungal prophylaxis in children with acute leukaemia: a multicentre retrospective Australian cohort study.

Background: Invasive fungal disease (IFD) is a significant complication for children receiving treatment for leukaemia, contributing to morbidity and mortality. Recent regional paediatric epidemiological IFD data are lacking. Additionally uncertainty remains regarding the optimal prophylactic approach in this context.

The role of convalescent plasma and hyperimmune immunoglobulins in the COVID-19 pandemic, including implications for future preparedness.

Introduction: When Coronavirus Disease-19 (COVID-19) struck the world in December 2019, initiatives started to investigate the efficacy of convalescent plasma, a readily available source of passive antibodies, collected from recovered patients as a therapeutic option. This was based on historical observational data from previous virus outbreaks.

Methods: A scoping review was conducted on the efficacy and safety of convalescent plasma and hyperimmune immunoglobulins for COVID-19 treatment.

Neuropsychological outcomes of patients with haematological malignancies undergoing chimeric antigen receptor T-cell therapy: protocol for a prospective study.

Introduction: Immune effector cell-associated neurotoxicity syndrome (ICANS) is a common side-effect of chimeric antigen receptor T-cell (CAR-T) therapy, with symptoms ranging from mild to occasionally life-threatening. The neurological, cognitive, psychiatric and psychosocial sequelae of ICANS are diverse and not well defined, posing a challenge for diagnosis and management. The recovery trajectory of the syndrome is uncertain.

Pulmonary complications post allogeneic haematopoietic stem cell transplant in children.

Objectives: Haematopoietic stem cell transplant (HCT) is a cellular therapy that, whilst curative for a child's underlying disease, carries significant risk of mortality, including because of pulmonary complications. The aims of this study were to describe the burden of pulmonary complications post-HCT in a cohort of Australian children and identify risk factors for the development of these complications.

Methods: Patients were identified from the HCT databases at two paediatric transplant centres in Australia.

A critical review of management of allogeneic transplant-eligible adults with Ph+ acute lymphoblastic leukaemia.

Acute lymphoblastic leukaemia (ALL) in 20%-30% of adult patients contains the Philadelphia (Ph+) chromosome. Historically, Ph+ ALL denoted a markedly inferior outcome and long-term survival in the absence of an allograft was uncommon. However, the advent of targeted therapy directed against the BCR::ABL1 fusion protein with various tyrosine kinase inhibitors (TKIs) has markedly improved the prognosis, resulting in a number of treatment controversies in allograft-eligible patients.

Outcomes with single-agent gilteritinib for relapsed or refractory FLT3-mutant AML after contemporary induction therapy.

Gilteritinib is the current standard of care for relapsed or refractory fms related receptor tyrosine kinase 3 (FLT3)-mutated acute myeloid leukemia in many countries, however outcomes for patients relapsing after contemporary first-line therapies (intensive chemotherapy with midostaurin, or nonintensive chemotherapy with venetoclax) are uncertain. Moreover, reported data on toxicity and health care resource use is limited. Here, we describe a large real-world cohort of 152 patients receiving single-agent gilteritinib in 38 UK hospitals.

Response to Single Agent Cyclosporin in Patients with Non-Severe Aplastic Anaemia.

Objective: To determine the effectiveness of cyclosporin A (CSA) monotherapy in treating patients with non-severe aplastic anaemia (NSAA).

Study Design: A cross-sectional observational study. Place and Duration of the Study: Department of Clinical Haematology, Armed Forces Bone Marrow Transplant Center, Rawalpindi, Pakistan, from January 2022 till December 2023.

Preneutropenic Fever in Patients With Hematological Malignancies: A Novel Target for Antimicrobial Stewardship.

Background: Many patients with hematological malignancy develop fever after chemotherapy/conditioning but before chemotherapy-induced neutropenia (preneutropenic fever [PNF]). The proportion of PNF with an infectious etiology is not well established.

Methods: We conducted a single-center, prospective observational substudy of PNF (neutrophils >0.

Impact of thrombocytopenia-associated c.-118C>T and c.-140C>G ANKRD26 5'UTR variants in three-generational pedigree.

Inherited thrombocytopenias (ITs) encompass a group of rare disorders characterized by diminished platelet count. Recent advancements have unveiled various forms of IT, with inherited thrombocytopenia 2 (THC2) emerging as a prevalent subtype associated with germline variants in the critical 5' untranslated region of the gene. This region is crucial in regulating the gene expression of , particularly in megakaryocytes.

Desmopressin for prevention of bleeding for thrombocytopenic, critically ill patients undergoing invasive procedures: A randomised, double-blind, placebo-controlled feasibility trial.

Thrombocytopenic patients have an increased risk of bleeding when undergoing invasive procedures. In a multicentre, phase II, blinded, randomised, controlled feasibility trial, critically ill patients with platelet count 100 × 10/L or less were randomised 1:1 to intravenous desmopressin (0.3 µg/kg) or placebo before an invasive procedure.

Comprehensive Characterization of Surface-Bound Proteins and Measurement of Fibrin Fiber Thickness on Extracorporeal Membrane Oxygenation Circuits Collected From Patients.

Objective: To characterize surface-bound proteins and to measure the thickness of fibrin fibers bound to extracorporeal membrane oxygenation (ECMO) circuits used in children.

Design: Single-center observational prospective study, April to November 2021.

Setting: PICU, Royal Children's Hospital, Melbourne, Australia.

The seasonal distribution of immune thrombotic thrombocytopenic purpura is influenced by geography: Epidemiologic findings from a multi-center analysis of 719 disease episodes.

Prior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5-year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included.
