AI Article Synopsis
- * It involved a retrospective cohort of 1,031 low-birth-weight infants, with 124 receiving sivelestat treatment, and measured outcomes at 36 weeks postmenstrual age.
- * Results showed no significant improvement in bronchopulmonary dysplasia-free survival rates or secondary outcomes between those treated with sivelestat and those who weren't.
Article Abstract
Background: Chorioamnionitis, or infiltration of the chorioamnion by neutrophils, is a risk factor associated with the development of bronchopulmonary dysplasia. Increased neutrophil elastase levels are observed in the tracheal aspirates of these patients.
Aims: To examine the effects of early administration of the selective neutrophil elastase inhibitor sivelestat, which is used to treat acute lung injury in adults, on bronchopulmonary dysplasia in extremely premature infants.
Study Design: Retrospective cohort study.
Subjects: This study included extremely low-birth-weight infants born at a gestational age<28weeks. Patients were divided into groups based on the receipt of sivelestat.
Outcome Measures: The primary outcome was the rate of bronchopulmonary dysplasia-free survival at a postmenstrual age of 36weeks, and the secondary outcomes included various clinically significant factors of neonatal mortality and morbidity and adverse events.
Results: Of the 1031 included neonates, 124 (12.0%) were treated with sivelestat. Significant differences between the groups were noted for gestational age, delivery method, fetal number, the frequency of chorioamnionitis, immunoglobulin M levels, and WBC counts. No differences were identified concerning the bronchopulmonary dysplasia-free survival rate at a postmenstrual age of 36weeks (adjusted odds ratio for sivelestat to control, 0.83; 95% confidence interval=0.53-1.30). Secondary outcomes did not significantly differ between the groups.
Conclusions: In extremely premature infants, early sivelestat use was not associated with an improved rate of survival without bronchopulmonary dysplasia at a postmenstrual age of 36weeks.

Bronchopulmonary dysplasia is a prevalent respiratory disorder posing a significant threat to the quality of life in premature infants. Its pathogenesis is intricate, and therapeutic options are limited. Besides genetic coding, protein post-translational modification plays a pivotal role in regulating cellular function, contributing complexity and diversity to substrate proteins and influencing various cellular processes.

Background: Preterm birth, particularly with lower gestational age and respiratory complications, can impact neurodevelopmental outcomes and participation in daily activities. Understanding how these children engage in everyday tasks, particularly from the perspective of their parents, is critical for assessing long-term health outcomes and quality of life.
Objectives: This study aims to assess parental perceptions of participation and daily performance in children born preterm, comparing early preterm infants with and without chronic lung disease, late preterms, and term-born children.

Children with bronchopulmonary dysplasia (BPD) often exhibit severe respiratory problems and significant pulmonary dysfunction during school age and adulthood. Exercise tests show a decline in cardiopulmonary function and physical performance in children with BPD, who also have a higher incidence of pulmonary hypertension. These children generally perform poorly in terms of intelligence, language, and motor development.

Background: Severe neonatal inflammatory conditions in very preterm infants (VPT: <32 weeks gestational age, GA) are linked to adverse neurodevelopmental outcomes. Differences in white matter (WM) microstructure of the corpus callosum (CC) have been observed at age 6 in VPT children with a history of severe neonatal inflammation. The goal of this study was to determine whether these CC differences can be detected at term-equivalent age using diffusion MRI (dMRI), and whether neonatal inflammation is associated with altered WM in additional tracts implicated in the encephalopathy of prematurity.
