Article Abstract
Background: Gastrointestinal perforation in extremely low birth weight infants, characterized by its rapid onset, multiple complications, and critical condition, poses a significant risk of infant mortality. The aim of this study was to investigate the clinical characteristics of pneumoperitoneum in extremely low birth weight infants (ELBWI) and explore the risk factors associated with gastrointestinal perforation in very low birth weight preterm infants. Additionally, we shared our surgical experiences in managing gastrointestinal perforation among extremely low birth weight infants.
Methods: The Department of Neonatology at Chengdu Women and Children's Central Hospital conducted a retrospective study on gastrointestinal perforation in extremely low birth weight infants (birth weight <1000 g) who were admitted between 2014 and 2021. After baseline analysis and comparing it with the control group, we identified the risk factors associated with gastrointestinal perforation in ELBWI by multiple logistic regression analysis. The Kaplan-Meier analysis was performed to assess the adverse effect of gastrointestinal perforation for survival in ELBW infants. Cox multivariate regression analysis was used to evaluate hazard level of different variables for ELBW infants survival.
Results: Hemodynamically significant patent ductus arteriosus (hsPDA)(p = 0.043, OR = 2.779) and sepsis (p = 0.014, OR = 2.265) were significant risk factors for gastrointestinal perforation in extremely low birth weight infants. The Cox proportional hazard model revealed that intraventricular hemorrhage (HR = 2.854, p＜0.001) Sepsis (HR = 1.645, p = 0.015) and gastrointestinal perforation (HR = 1.876, p = 0.008) had detrimental effects on the survival of extremely low birth weight infants; conversely, ibuprofen (HR = 0.304, p＜0.001) and blood transfusion (HR = 0.372, p＜0.001) are beneficial factors for their survival. The preoperative indicators of infection in infants with spontaneous intestinal perforation (SIP) were significantly better than those in the necrotizing enterocolitis (NEC) group (p < 0.05).
Conclusions: Gastrointestinal perforation poses a significant threat the survival of extremely low birth weight (ELBW) infants, with hsPDA and sepsis serving as predisposing factors for gastrointestinal perforation. The gastrointestinal perforation caused by various diseases exhibits distinct clinical characteristics, necessitating tailored surgical approaches based on operative conditions.

Importance: For the first time in nearly 2 decades, the US infant mortality rate has increased, coinciding with a rise in overdose-related deaths as a leading cause of pregnancy-associated mortality in some states. Prematurity and low birth weight-often linked to opioid use in pregnancy-are major contributors.
Objective: To assess the health and economic impact of perinatal opioid use disorder (OUD) treatment on maternal and postpartum health, infant health in the first year of life, and infant long-term health.

Soybean meal (SBM) contains many bioactive compounds, such as isoflavones, which possess anti-inflammatory and anti-oxidative properties that may provide nutritional intervention to pigs infected with porcine reproductive and respiratory syndrome virus (PRRSv). The disease results in abortions, stillborn piglets, and overall impairs reproductive success in sows. Today, there are no data available on feeding SBM to sows infected with PRRSv to mitigate the negative impacts of PRRSv on sow and litter performance.

Introduction: Micro-RNAs (miRNAs) participate in different biological processes, including fetal hypoxia. In this work, we aimed to evaluate the existence of a miRNA differential expression profile in maternal blood of pregnancies affected with late-onset fetal growth restriction (LO-FGR).
Methods: In a prospective study, a group of 35 fetuses were evaluated with Doppler ultrasound after 36 weeks.
