Article Abstract
Intestinal perforation occurring in extremely low gestational age neonates is a devastating complication, associated with high mortality and morbidity. Multiple phenotypes of bowel perforation in premature infants have been described, with the most common being spontaneous, or isolated, intestinal perforation and perforated necrotizing enterocolitis. The purpose of this article is to summarize literature describing "meconium obstruction of prematurity", increasingly recognized as a distinct clinical phenotype in the smallest and most immature neonates. The goal of this review is to improve international recognition and understanding of this high-risk clinical condition. The lack of standardized nomenclature has been an obstacle to progress in understanding, preventing, and treating this important and more frequently encountered condition. The recognition of meconium obstruction requiring medical or surgical management is a clear distinguishing factor from other bowel pathologies of prematurity.

Purpose: To investigate the effectiveness of an aggressive treatment strategy for meconium-related ileus (MRI) in extremely low birth weight infants (ELBWIs).
Methods: Since April 2018, we have implemented a novel protocol, incorporating early Gastrografin injection, aggressive enema therapy, and early surgery without perforation (ES). Among 362 ELBWIs treated at our institute over the past 15 years, 91 with MRI were included in this study.

Purpose: Neonatal bowel obstruction secondary to inspissated meconium has been historically associated with cystic fibrosis. Increasingly, meconium-related obstruction (MRO) has been observed in preterm infants. We conducted a multicenter mixed-methods study to better characterize the contemporary experience with MRO.

: Cystic fibrosis (CF) is a rare autosomal recessive genetic disease that has a progressive and multisystemic course. The spectrum and frequency of mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) vary both in European countries and in other geographical regions. The aim of our retrospective study was to present the genetic variants identified in a group of 48 CF patients from the Moldova region (Romania), as well as to establish genotype-phenotype correlations.

Background: Data from cystic fibrosis (CF) animal models and case studies suggests that in utero administration of CF transmembrane conductance regulator (CFTR) modulators (variant specific therapies, VST) can rescue CFTR-related pathophysiology in the fetus. Use of VST during pregnancy to prevent disease in infants has not been systematically studied. Through stakeholder engagement, we sought to determine if formal research evaluation is warranted.
