Background: Metagenomic next-generation sequencing (mNGS) has become a valuable diagnostic tool in clinical etiology detection due to its rapidity, accuracy, and high throughput. However, the role of this technology in the diagnosis and treatment of infants with severe pneumonia after congenital heart surgery is still unclear.
Methods: We conducted a retrospective cohort study of infants with severe pneumonia after congenital heart surgery. Samples were collected from infants in the hospital's cardiac intensive care unit between January 2010 and January 2022. The conventional microbiological test (CMT) group consisted of patients who underwent routine microbiological examination, and the infants' bronchoalveolar lavage fluid was examined. The mNGS group consisted of patients who underwent mNGS and routine microbiological examinations.
Results: The overall positive rate of mNGS was significantly higher than that of CMT (88.4 vs. 62.5%, = 0.009). After receipt of the microbiological results, 30/43 (70%) patients in the mNGS group had a change in antibiotic use compared with 14/40 (35%) in the CMT group ( = 0.002). Subsequently, after adjusting the treatment plan according to the microbiological test results, the number of people with improved pulmonary infection in the mNGS group was significantly higher than that in the CMT group (63 vs. 28%, < 0.05). In addition, the duration of invasive ventilation, length of CICU stay and total hospital length of stay in the mNGS group were significantly lower than those in the CMT group ( < 0.05).
Conclusion: mNGS is a valuable tool to determine the etiology of infants with severe pneumonia after congenital heart disease surgery. It can significantly improve the sensitivity of pathogen detection, which can help determine appropriate antimicrobial drugs, improve the diagnostic accuracy of the disease, and improve outcomes.

Unbound bilirubin and risk of severe neurodevelopmental impairment in extremely low birthweight newborns.
Pediatr Res
January 2025
Division of Neonatal and Developmental Medicine, Department of Pediatrics, Stanford University School of Medicine, Palo Alto, CA, USA.
Background: Unbound bilirubin (UB) was measured on day 5 ± 1 in 1101 ELBW newborns in the Aggressive vs Conservative Phototherapy randomized controlled trial. We accessed this dataset to quantify the UB-mediated risk of severe neurodevelopmental impairment (sNDI) in extremely low birthweight (ELBW) newborns.
Methods: UB levels were standardized within laboratories as z-score percentiles.

Division of Pediatric Cardiology, Department of Pediatrics, Hasbro Children's Hospital, The Warren Alpert Medical School at Brown University, Providence, RI, USA.
Prenatal diagnosis of congenital heart disease requiring early cardiac catheterization or surgical intervention enables optimal delivery planning for appropriate postnatal cardiovascular intervention and care. This allows for improved morbidity and mortality. Prior national data reported prenatal diagnosis rates of 32% for congenital heart disease requiring intervention in infants in the first 6 months of life in the New England region.

Faculty of Psychology, SWPS University in Katowice, Poland.
Background: Social support and maternal self-efficacy are important protective factors against depression. However, the contribution of these variables to postpartum depression in the context of persistent maternal fatigue and prolonged unrestrained infant crying is unclear.
Objectives: This study aimed to explore possible mediating roles of maternal chronic fatigue, infant crying intensity, and frustration as a maternal emotional response to infant crying on the relationship between social support, maternal self-efficacy and maternal depression.

Background: Respiratory syncytial virus (RSV) is a major cause of severe health problems in newborns and young children. The protective role and limitations of serum maternal RSV antibodies in infants under 3 months remain controversial.
Methods: A two-center prospective study from 2020 to 2023 recruited infants (n=286) admitted to the respiratory departments of two children's hospitals in southwestern and southeastern China during RSV epidemic.
