Preterm less than 33 weeks
This cohort will be composed of premature infants born before 33 weeks of gestational age, admitted to the neonatal intensive care unit at Sainte-Justine hospital and receiving parenteral nutrition (PN) during their first week of life.
- Bronchopulmonary Dysplasia [ Time Frame: 4 Months ]To correlate the level of urinary Ascorbyl peroxide and BPD. Full diagnosis and classification (to mild, moderate or severe) is at 36 weeks of corrected age; so even for most premature infants (like 23 weeks of gestation) there will be a need for follow up for less than 4 month to have the final diagnosis at 36 weeks
- The redox status (in blood) [ Time Frame: First week of life (week 1) and 36 semaines CA ]Testing the correlation between the urinary level of ascorbyl peroxide and the redox status in the blood at 5 to 7 days of life. Measuring the Redox potential at 36 weeks corrected age to investigate long term effect of early oxidative stress.
- Major neonatal outcomes (NEC, ROP, PDA, IVH, PVL) [ Time Frame: 4 Months ]These outcomes are the major neonatal outcomes for preterm infants, we would test the correlation between ascorbyl peroxide (as marker of oxidative stress) and like Necrotising enterocolotis (NEC), Retinopathy of prematurity (ROP),patent ductus arteriosis(PDA), intraventricular hemorrhage (IVH) and periventricular leucomalacia (PVL).
