P. aeruginosa bacteremia in children is rare but often fatal if initial antibiotics do not cover P. aeruginosa. Factors indicative of P. aeruginosa bacteremia remain elusive, especially in previously healthy young children. However, P. aeruginosa bacteremia should be considered if children present with a grave illness, seizures, serious gastrointestinal findings, hypotension, and leukopenia.

Background: This study aimed to describe the causative organisms of neonatal late-onset sepsis (LOS) and their antimicrobial resistance in Suzhou, Southeast China over a 7-year period. Methods: We performed a retrospective study on neonates with LOS from Jan1, 2011 to Dec 31, 2017. The demographic, clinical, and laboratory data of neonates with LOS were analyzed. Logistic regression was used to investigate the risk factors with mortality. Results: During the study period, 202 neonates with LOS were finally identified. The most common pathogens were Escherichia coli (29.2%), followed by Klebsiella pneumoniae (19.3%), and Coagulase-negative Staphylococcus (CoNS) (16.8%). Nearly 90% of the K. pneumoniae were resistant to cefazolin and 71.8% to ceftazidime. Thirty-four patients (16.8%) died. Multivariable logistic regression showed that significant predictors of mortality were birth weight < 1500 g, respiratory distress and convulsions. Conclusions: Gram-negative organisms have an important role in LOS in our region, with high levels of resistance to third-generation cephalosporins. These data may help in the selection of antibiotics for empirical treatment of neonates with sepsis.

Acute lung injury (ALI) caused by sepsis is a common respiratory critical illness with high morbidity and mortality. Protein kinase C-alpha (PRKCA) plays a protective role in sepsis-induced ALI.

Background: Published data and practice recommendations on end-of-life care generally reflect Western practice frameworks; there are limited data on withdrawal of treatment for children in China. Methods: Withdrawal of treatment for children in the pediatric intensive care unit (PICU) of a regional children's hospital in eastern China from 2006 to 2017 was studied retrospectively. Withdrawal of treatment was categorized as medical withdrawal or premature withdrawal. The guardian's self-reported reasons for abandoning the child's treatment were recorded from 2011. Results: The incidence of withdrawal of treatment for children in the PICU decreased significantly; for premature withdrawal the 3-year average of 15.1% in 2006-2008 decreased to 1.9% in 2015-2017 (87.4% reduction). The overall incidence of withdrawal of care reduced over the time period, and withdrawal of therapy by guardians was the main contributor to the overall reduction. The median age of children for whom treatment was withdrawn increased from 14.5 months (interquartile range: 4.0-72.0) in 2006 to 40.5 months (interquartile range: 8.0-99.0) in 2017. Among the reasons given by guardians of children whose treatment was withdrawn in 2011-2017, "illness is too severe" ranked first, accounting for 66.3%, followed by "condition has been improved" (20.9%). Only a few guardians ascribed treatment withdrawal to economic reasons. Conclusions: The frequency of withdrawal of medical therapy has changed over time in this children's hospital PICU, and parental decision-making has been a large part of the change.
