Official title
The Association Between Umbilical Cord Blood Vitamin A Levels and Adverse Outcomes in Extremely Preterm Infants: A Single-Center Prospective Cohort Study
Overview
This single-center prospective cohort study aims to describe the distribution of umbilical-cord blood vitamin A concentrations in extremely preterm infants (\<32 weeks' gestation) and to evaluate whether low cord blood vitamin A is associated with increased risk of neonatal morbidities such as bronchopulmonary dysplasia (BPD), necrotising enterocolitis (NEC), severe intraventricular haemorrhage (IVH), retinopathy of prematurity (ROP), periventricular leukomalacia (PVL), high-grade patent ductus arteriosus (hsPDA), respiratory distress syndrome (RDS), sepsis and death before discharge.
Primary outcome measures
- Composite adverse neonatal outcome (any of death, moderate-severe BPD, NEC≥stage II, IVH≥grade III, ROP≥stage 3, PVL, hsPDA, culture-proven sepsis) [Time frame: From birth to 36 weeks' PMA or discharge, up to 3 months chronological age.]
