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 randomly 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 randomized, 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, clinically 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, Inc.

Impact of educational programme regarding chelation therapy on the quality of life for B-thalassemia major children.

Objectives Thalassemia is the most common genetic disorder in Egypt, with an estimated carrier rate of 9-10%. It is a genetic blood disorder which can be fatal if proper chelation is not received. The introduction of chelating agents capable of removing excessive iron from the body has dramatically increased life expectancy and improved the overall quality of life. The aim of this study was to assess the impact of educational programmes regarding chelation therapy on the quality of life of thalassemic children. Methods The study was carried out at the Mansoura University Children's Hospital in the period between March 2010 and May 2011. It included 173 B-thalassemia children (84 boys and 89 girls) with age ranging between 8-18 years. The researcher used a predesigned interviewing questionnaire to collect data regarding children's knowledge about thalassemia and its management, especially regarding chelation therapy. The paediatric quality-of-life inventory tool (Peds QL 4.0 generic core) was also used to assess the studied children's quality of life. Results There was a significant statistical difference of the studied children's knowledge regarding chelation therapy and their quality of life. Conclusion There was a positive effect of the educational programme in improving children's knowledge score and their quality of life. Application of educational programmes for thalassemic children and their nurses regarding chelation therapy and its importance in preventing thalassemia complications is established.

Non-nutritive sucking for preterm infants in Egypt.

OBJECTIVE: To assess how non-nutritive sucking (NNS) using a pacifier affected physiological and behavioral outcomes of preterm infants. DESIGN: Short-term longitudinal, experimental design. SETTING: The study took place at the neonatal intensive care unit at Al-Mansoura, Egypt. METHODS: Forty-seven preterm infants were divided into intervention and control groups. Preterm infants in the intervention group received NNS during nasogastric tube feeding while infants in the control group never received NNS. During 10 days, behavioral responses were videotaped and physiological responses were monitored. RESULTS: Significantly higher oxygen saturation occurred during and after nasogastric feeding for the intervention infants as compared to the control group. No significant group differences occurred in heart rate. The NNS group showed an accelerated transition to nipple feeding and had better weight gain and earlier discharge. CONCLUSION: Non-nutritive sucking was found to improve physiological and behavioral responses of preterm infants.
