Serial Assessment of Body Fat Accrual in Very Preterm Infants

Despite evidence that both rapid weight gain and excessive body fat accrual are associated with overweight and obesity, usual neonatal care of preterm infants does not include assessment of body fat accrual. The study hypothesis is that identification of early changes in infant body composition (i.e. amount of fat mass and fat-free mass) reduces % body fat at 3 months of age.

Effects of Closed-loop Automatic Control of FiO2 in Extremely Preterm Infants

Extremely low gestational age neonates (ELGANs), i.e. those born at \<28 weeks, frequently experience intermittent hypoxemic/hyperoxemic episodes. Observational data indicate that severe and prolonged hypoxemic episodes are associated with retinopathy of prematurity (ROP), impaired long-term development and death. Closed-loop automated control of the inspiratory fraction of oxygen (FiO2-C) reduces time outside the oxygen target range, decreases number and duration of hypo- and hyperoxemic episodes, and reduces caregivers' workload. The proposed observer-blinded randomized controlled trial was designed and will be powered to compare the effect of FiO2-C in addition to manual adjustments, in comparison with manual adjustments of FiO2 only, on death and severe complications of prematurity thought to be related to hypoxia/hyperoxia and neurodevelopmental impairment in ELGANs. The results of this trial may help to improve the quality of life of ELGANs and reduce the burden of significant morbidity as well as costs for health care and society
