Comprehensive assessment of placental inflammation: Novel approach in predicting retinopathy of prematurity.

The purpose of this study was to determine the independent association between placental inflammation and the development of retinopathy of prematurity (ROP). This retrospective cohort study included 591 neonates born with a gestational age (GA) ≤32 weeks and/or a birthweight (BW) ≤1500 g. Clinical data were retrospectively collected, and placentas were reexamined for acute (e.

Difference in adverse neonatal outcomes between preterm singletons and twins possibly explained by placental abnormalities.

Introduction: The purpose of this study was to compare microscopic placental characteristics between preterm twins and singletons, and between preterm monochorionic and dichorionic twins, in order to explore the effect of placental pathology on adverse neonatal outcomes.

Methods: This study included 566 neonates born ≤32 weeks and/or ≤1500 g, of whom 429 were singletons and 137 were twins (38 monochorionic and 99 dichorionic). Clinical data was retrospectively collected, and placentas were prospectively examined for maternal vascular malperfusion, fetal vascular malperfusion and placental inflammation (acute and chronic).

The association between red blood cell transfusion timing and the development of retinopathy of prematurity: Application of the two-phase theory.

Purpose: Red blood cell (RBC) transfusions are believed to be associated with retinopathy of prematurity (ROP), but the underlying mechanism is not fully understood, partly due to the lack of information on RBC transfusion timing. The aim was to determine the association between the timing and amount of RBC transfusions and the development and severity of ROP.

Methods: This retrospective dual-center cohort study included 1177 neonates born in 2004-2022 with a gestational age at birth ≤28 weeks.

Enhancing the Retinopathy Of Prematurity Risk Profile Through Placental Evaluation of Maternal and Fetal Vascular Malperfusion.

Purpose: To determine the independent effect of uteroplacental malperfusion on the development of retinopathy of prematurity (ROP).

Methods: This cohort study included 591 neonates with a gestational age (GA) ≤ 32 weeks or birthweight (BW) ≤ 1500 g. Clinical data was retrospectively collected and placentas were prospectively examined for maternal vascular malperfusion (e.

Early-Onset Sepsis as an Early Predictor for Retinopathy of Prematurity: A Meta-analysis.

Objective:  Neonatal sepsis has been established as a risk factor for retinopathy of prematurity (ROP) but previous meta-analyses have predominately focused on late-onset sepsis (LOS). This meta-analysis aims to explore the association between early-onset sepsis (EOS) and the risk of ROP.

Study Design:  Observational studies reporting (unadjusted) data on proven EOS in neonates with ROP were included.
