Fibrinolytic activity in infants undergoing cardiac surgery on cardiopulmonary bypass with routine tranexamic acid: A prospective cohort substudy within the FIBrinogen CONcentrate randomised control trial.

Background: Fibrinolytic activity contributes to bleeding after cardiopulmonary bypass (CPB).

Objective: Our objectives were, in a group of infants undergoing cardiac surgery with CPB: to document the extent of peri-operative fibrinolysis using rotational thromboelastometry (ROTEM) and standard biomarkers; to compare the agreement between these fibrinolytic measures; to assess whether fibrinolytic activity is associated with early postoperative mediastinal bleeding and assess whether supplementation with fibrinogen concentrate affected fibrinolysis.

Design: Prospective cohort, mechanistic substudy, nested within the FIBrinogen CONcentrate (FIBCON) randomised controlled trial.

Shared neutrophil and T cell dysfunction is accompanied by a distinct interferon signature during severe febrile illnesses in children.

Severe febrile illnesses in children encompass life-threatening organ dysfunction caused by diverse pathogens and other severe inflammatory syndromes. A comparative approach to these illnesses may identify shared and distinct features of host immune dysfunction amenable to immunomodulation. Here, using immunophenotyping with mass cytometry and cell stimulation experiments, we illustrate trajectories of immune dysfunction in 74 children with multi-system inflammatory syndrome in children (MIS-C) associated with SARS-CoV-2, 30 with bacterial infection, 16 with viral infection, 8 with Kawasaki disease, and 42 controls.

Parent and staff experiences of a feasibility trial evaluating neurally adjusted ventilatory assist in infants with acute viral bronchiolitis: A qualitative study.

Background: There is limited literature regarding family and staff experiences of participating in clinical trials. A qualitative study was embedded in the NAVABronch feasibility trial evaluating the effectiveness of a novel mode of ventilation, neurally adjusted ventilatory assist (NAVA), in infants with acute viral bronchiolitis.

Aim: The aim of this qualitative study was to explore the experiences of parents and health care practitioners (HCPs) involved in the NAVABronch Trial.
