Conclusion Current evidence suggests that developmental care in only NICU setting could have significant effect on mental and motor development of preterm infants , especially at 12 months of age .
Background The aim of this study was to review the effects of developmental care in neonatal intensive care unit ( NICU ) setting on mental and motor development of preterm infants .
Timing for the Introduction of Cycled Light for Extremely Preterm Infants: A Randomized Controlled Trial
Day-night cycled light improves health outcomes in preterm infants , yet the best time to institute cycled light is unclear . The hypothesis of this study was that extremely preterm infants receiving early cycled light  would have better health and developmental outcomes than infants receiving  late cycled light .  Infants born at ≤28 weeks gestation were r and omly assigned to early cycled light ( ECL ) starting at 28 weeks postmenstrual age [ PMA ] or late cycled light ( LCL ) , starting at 36 weeks PMA . Daylight was 200 - 600 lux and night was 5 - 30 lux . Primary outcomes were weight over time and length of hospitalization . Secondary outcomes were hospital costs , sleep development , and neurodevelopment at 9 , 18 , and 24 months corrected age . Of 121 infants r and omized , 118 were included in analysis . Weight gain in the two groups did not differ significantly but increased across time in both groups . In PMA weeks 36 - 44 , the mean weight gain was 193.8 grams in the ECL group compared to 176.3 grams in the LCL group . Effect sizes for weight were Cohen d = 0.26 and 0.36 for 36 and 44 weeks PMA . Infants in the ECL group went home an average of 5.5 days earlier than the LCL group , but this difference was not statistically significant . There were no group differences on neurodevelopmental outcomes . Although statistically non-significant , clinical ly important differences of improved weight gain and decreased hospital stay were observed with ECL . The small observed effect sizes on weight during hospitalization should be considered in future cycled light research with extremely preterm infants . © 2017 Wiley Periodicals ,
