Objective: To examine erythroferrone (ERFE)-hepcidin iron regulation in premature infants under intensive care at risk of iron metabolic disorders.
Study Design: A retrospective cohort recruited 31 infants with a birth weight of <1500 g hospitalized in a tertiary center. Their hematological status was measured at birth and 2 and 4 weeks of life.
Results: ERFE was positively correlated with the reticulocyte hemoglobin content at 2 (r = 0.2374) and 4 weeks (r = 0.6005). An assumed negative correlation between ERFE and hepcidin was not determined during the neonatal period. Hepcidin was positively correlated with the leukocyte count (r = 0.3089) and ferritin (r = 0.7476) at birth and C-reactive protein (r = 0.3591) at 2 weeks and negatively correlated with the reticulocyte count (r = 0.2887) at 4 weeks.
Conclusion: The vulnerability of the ERFE-hepcidin pathway within 4 weeks may contribute to iron imbalance in premature infants.

Department of Neonatology, Children's Hospital of Soochow University, Suzhou, China.
This study investigated the correlation between quantitative echocardiographic characteristics within 3 days of birth and necrotizing enterocolitis (NEC) and its severity in preterm infants. A retrospective study was conducted on 168 preterm infants with a gestational age of < 34 weeks. Patients were categorized into NEC and non-NEC groups.

Retrospective Analysis of the Correlation between Umbilical Blood Flow Index and Maternal and Fetal Outcomes in Pregnant Women with Gestational Diabetes.
Br J Hosp Med (Lond)

Department of Obstetrics and Gynecology, The First Clinical Medical College of Three Gorges University, Yichang Central People's Hospital, Yichang, Hubei, China.
Gestational diabetes mellitus (GDM) is a common complication during pregnancy. This retrospective study investigates the correlation between umbilical blood flow index and maternal-fetal outcomes in pregnant women with GDM, aiming to contribute to evidence-based risk assessment and management strategy in this high-risk obstetric population. This retrospective study recruited 119 pregnant women with GDM who were admitted to the Yichang Central People's Hospital, between January 2022 and January 2024.

Nutrients

Neonatal Intensive Care Unit, Department of Women's and Children's Health, University Hospital of Padova, 35128 Padova, Italy.
Background: Preterm infants (PIs) are more susceptible to neurodevelopmental impairment compared with term newborns. Adequate postnatal growth has been associated with improved neurocognitive outcomes; therefore, optimization of nutrition may positively impact the neurodevelopment of PIs.
Objective: This study focused on macronutrient parenteral nutrition (PN) intake during the Neonatal Intensive Care Unit stay and their associations with neurodevelopmental outcomes in PIs in the first two years of life.
Microbial Pattern in Amniotic Fluid from Women with Premature Rupture of Membranes and Meconium-Stained Fluid.

Intra-amniotic infection (IAI), also known as chorioamnionitis, is a major cause of maternal and neonatal infection that occurs during pregnancy, labor and delivery, or in the postpartum period. Conditions such as meconium-stained amniotic fluid (MSAF) and premature rupture of membranes (PROMs) are recognized risk factors for amniotic fluid infection. This study identifies the microbial patterns in the amniotic fluid of women with PROMs and MSAF to determine the presence and types of bacterial growth.
