are a large order of ubiquitous saprophytic zygomycete fungi and act as opportunistic pathogens in humans. In pediatric patients, little is known about the role of in airway colonization and infection or their role as contaminants of respiratory samples. Currently, polymerase chain reaction (PCR) is the most sensitive mode of detection in clinical specimen.

Recently, cystic fibrosis transmembrane regulator modulator therapy with elexacaftor/tezacaftor/ivacaftor has become available for children with cystic fibrosis (CF) carrying at least one mutation. To assess the intermediate term effects of elexacaftor/tezacaftor/ivacaftor in children with cystic fibrosis in a real-world setting. We performed a retrospective analysis of records of children with cystic fibrosis, who started elexacaftor/tezacaftor/ivacaftor between 8/2020 and 10/2022.

Article Synopsis
  • Mycobacterium chimaera is a non-tuberculous mycobacterium linked to difficult infections in cystic fibrosis patients, primarily affecting the lungs and rare in other sites unless there's immune deficiency.
  • A case study of an 8-year-old cystic fibrosis patient showed recurrent pulmonary issues and a confirmed M. chimaera infection in a central venous port, diagnosed using next-generation sequencing.
  • The patient's recovery highlights the need for catheter removal and targeted therapy as key steps in treating MAC infections, underscoring the importance of biofilm formation in such cases.

Background: Respiratory involvement defines the clinical outcome of neuromuscular diseases (NMD). The lung clearance index (LCI) is a marker of lung ventilation inhomogeneity and indicates small airway disease. It is determined by mulitple breath washout lung function (MBW).

High-flow nasal therapy (HFNT) is a safe and simple way to deliver humidified air and oxygen for respiratory support in infants and children. HFNT is well established in an inpatient setting, but home HFNT lacks evidence. In the current study, we studied characteristics and outcomes of pediatric patients with home HFNT.
