Pediatric ECMO Outcomes in Children With Severe Infections: Does Infectious Source Matter?
J Pediatr Surg
January 2025
Division of Pediatric Surgery, Department of Surgery, Phoenix Children's Hospital, Phoenix AZ, USA.
Background: Although Extracorporeal Membrane Oxygenation (ECMO) utilization in pediatric patients with cardiopulmonary failure due to infection improves mortality, it is unclear whether the infectious etiology impacts outcomes. The aim of this study is to compare ECMO outcomes in children with sepsis and severe acute lung injury secondary to infections based on culture data.
Methods: A retrospective review was done of patients aged <18 with severe infections whose management included ECMO from 2013 to 2022 at a quaternary children's hospital.
Cleaning and sterilization are critical Prerequisite Programs in sanitation management based on HACCP. Most food factories clean and sanitize equipment daily after production using detergents containing benzalkonium chloride (BAC). However, in factories that produce oil and fat-rich foods, it has been discovered that microbes can persist on production equipment.

The limited understanding of microbial response mechanism remains as a bottleneck to evaluate the long-term remediation effectiveness of in situ chemical oxidation in contaminated groundwater. In this study, we investigated long-term response of bacterial communities throughout five remediation stages of pre-oxidation, early-oxidation, late-oxidation, early-recovery and late-recovery. By analyzing bacterial biomass, taxa, diversity and metabolic functions, this work identified the consistently suppressed glyceraldehyde-3-phosphate dehydrogenase pathway and the enrichment of naphthalene degradation pathways for secondary products, suggesting persistent oxidation stress and enhanced microbial utilization of lower-molecular weight carbon sources at the oxidation and early-recovery stages.

Exposure to influenza A virus (IAV), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) is well-known to increase the risk of pneumonia in humans. Type I interferon (IFN-I) is a hallmark response to acute viral infections, and alveolar macrophages (AMs) constitute the first line of airway defense against opportunistic bacteria. Our study reveals that virus-induced IFN-I receptor (IFNAR1) signaling directly impairs AM-dependent antibacterial protection.

Marine resources are attractive for screening new useful bacteria. From a marine sediment sample, we performed isolation and screening of bacterial strains in search of new bioactive compounds. HPLC and ESI-MS analysis indicated that the new bacterium, Lysinibacillus sp.
