Background: The effects of blood transfusions on splanchnic oxygenation and complications related to blood transfusions, including red blood cell (RBC) transfusions, in premature infants undergoing enteral feeding, to provide clinical evidence for a management protocol for premature infants during the peri-transfusion period.
Methods: This single-blind, randomized, controlled trial enrolled sixty eligible preterm infants who were randomly divided into the withholding feeding group ( = 30) or feeding group ( = 30). Enteral feeding was withheld for 8 h, beginning from the start of transfusion infants in the feeding group were fed according to the pre-transfusion feeding approach during and after RBC transfusion.
Results: Baseline characteristics of those in the withholding and feeding groups were as follows: gestational age (weeks) 27.52 (24.86-30.14) and 27.13 (25.43-30.14); birth weight (g), 1,027 (620-1,450) and 1,027 (620-1,270); blood transfusion day, 48 (14-79) and 39 (10-78); and hemoglobin before blood transfusion (g/L), 81.67 (±10.56) and 85.93 (±14.77). No significant differences were observed between groups at baseline. No significant differences were observed in the average splanchnic tissue oxygenation changes or clinical results at any time. One patient in the withholding feeding group experienced transfusion-associated necrotizing enterocolitis.
Conclusions: No differences in splanchnic oxygenation observed these feeding protocols. This study suggests the feasibility of a sizable trial to evaluate clinical outcomes. The risks of mesenteric ischemia and transfusion-related necrotizing enterocolitis for premature infants were not increased by enteral feeding during RBC transfusion.

Diagnostic accuracy of gasdermin D as a biomarker for necrotizing enterocolitis: a single-center diagnostic test study.
Transl Pediatr

Department of Neonatology, Yunnan First People's Hospital, Kunming, China.
Background: Necrotizing enterocolitis (NEC) is a devastating gastrointestinal condition mainly affecting premature infants, and gasdermin D (GSDMD) has emerged as a molecule of interest due to its pivotal role in the inflammatory process called pyroptosis in NEC pathogenesis. The aim of this study is to examine the potential of GSDMD and interleukin-1β (IL-1β) as early diagnostic biomarkers for NEC.
Methods: We examined 207 infants with clinical symptoms of NEC admitted to our neonatal intensive care unit (NICU) between December 2023 and June 2024.

Objectives: The study was conducted to investigate the effect of swing on stress and comfort in premature newborns who could not be reunited with their mothers.
Methods: The study was conducted in a randomised controlled experimental design. The intervention group included newborns who received swing intervention (n = 64) and the control group included newborns who did not receive swing intervention (n = 64).

The administration of surfactant aerosol therapy to preterm infants receiving continuous positive airway pressure (CPAP) respiratory support is highly challenging due to small flow passages, relatively high ventilation flow rates, rapid breathing and small inhalation volumes. To overcome these challenges, the objective of this study was to implement a validated computational fluid dynamics (CFD) model and develop an overlay nasal prong interface design for use with CPAP respiratory support that enables high efficiency powder aerosol delivery to the lungs of preterm infants when needed (i.e.

Background: The study of women exposures and child outcomes occurring in the first 1,000 days of life since conception enhances understanding of the relationships between environmental factors, epigenetic changes, and disease development, extending beyond childhood and spanning the entire lifespan. Generation Gemelli is a recently launched case-control study that enrolls mother-newborns pairs in one of the largest university hospitals in Italy, in order to examine the association between maternal environmental exposures and intrauterine growth restriction (IUGR) and the risk of premature birth. The study will also evaluate the association of maternal exposures and the health and growth of infants and children up to 24 months of age.
