| 1. Neonatal complications typically associated with respiratory insufficiency and very low birth weight (VLBW): 1.1. Bronchopulmonary dysplasia (BPD) is diagnosed in all infants who still require supplemental oxygen at a postconceptual age of 36 weeks. In addition, quantitative comparisons of the duration of support will be performed (days on positive pressure ventilation via endotracheal tube, days on non-invasive continuous positive airway pressure [CPAP], days in oxygen) 1.2. Intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL) and ventriculomegaly are diagnosed ultrasonographically. Serial cranial ultrasound assessments are routinely performed in VLBW infants to detect hemorrhagic and ischemic changes. The worst scans obtained between days 14 and 28, and between 34-36 weeks post conception, respectively, will be recorded 1.3. Necrotising enterocolitis (NEC) is diagnosed at surgery, at autopsy, or by either the finding of pneumatosis intestinalis, hepatobiliary gas or free intraperitoneal air on abdominal X-ray. In the absence of these findings, suspected NEC is recorded in any infant in whom enteral feeds are withheld for more than 5 days, because of symptoms and signs suggestive of NEC 1.4. Retinopathy of prematurity (ROP) is diagnosed at routine ophthalmologic examinations, beginning at 32 weeks postconceptional age. The severity of ROP will be graded according to the international classification of ROP 2. Weight gain and head circumference will be recorded weekly until discharge from the study centre 3.
