Aim: To describe parental perspective on health and developmental outcomes of their preterm child in relation to level of neurodevelopmental impairment (NDI). Methods:A parental survey about their children aged 15-36 months corrected age born ˂29 weeks' gestation investigated parental concerns and positive attributes.Parental responses in relation to their child's level of NDI were examined using Kruskal-Wallis and chi-square for trend tests.Results: One hundred ninety-nine parental responses were obtained for 163 children, including 44% with NDI. Vast majority of parents reported their children were developing well with good physical health. All parents, irrespective of NDI, reported their children were happy and had a positive personality. Appreciation of social interactions was higher for parents of children without versus with NDI (96% vs. 87%, p = 0.039).Parents of children with NDI were more likely to express concerns than those without NDI. Overall, development was the most common area of concern (45%), followed by the child's future (40%) and physical health (35%). Conclusion:Parents of preterm children report many positive points and concerns, some of which are not examined in neonatal follow-up data. These parental perspectives could be used to inform parents of preterm infants, both antenatally and in the neonatal unit.

Background Sodium fluctuations in very preterm neonates and their neurodevelopmental consequences are not well described. Methods We assessed the changes in plasma sodium and glucose in the first days of life in very preterm neonates and studied the association of glucose-corrected plasma sodium fluctuations on neurodevelopmental outcomes. We included 147 consecutive neonates born before 29 weeks of gestation in our center and retrospectively obtained plasma sodium, glucose, and glucose-corrected sodium levels. Neurodevelopmental assessment was obtained from the Canadian Neonatal Follow-Up Network. Results Mean ± standard deviation of plasma sodium changes within the first 10 days of life were 16.2 ± 6.0, 14.8 ± 5.3, and 11.1 ± 5.2 mmol/l in neonates born ≤25, 25–26, and 26–27 weeks of gestation, respectively ( p < 0.001). Non-steroidal anti-inflammatory drug administration was associated with larger plasma sodium fluctuation. Eighty-six percent had a known neurological status at 18 months. Higher fluctuations in glucose-corrected plasma sodium were associated with death or neurodevelopmental impairment at 18 months corrected age ( B = 3.19, 95% CI [1.24, 5.14]), and this association remained after adjustment for gestational age ( B = 2.1, 95% CI [0.16, 4.04]). Conclusions Neonates born very preterm show fluctuations in glucose-corrected plasma sodium during the first days of life, which may increase the risk of death or developmental impairment. Impact Risk factors and neurodevelopmental consequences of plasma sodium changes in early neonatal life of preterm infants are not well characterized. This study shows for the first time that glucose-corrected plasma sodium fluctuations within the first days of life are more severe in preterm infants receiving non-steroidal anti-inflammatory drugs (NSAIDs) and are associated with death or neurodevelopmental impairment at 18 months corrected age. Large plasma sodium and glucose fluctuations should be expected more often in preterm infants receiving NSAIDs and should be avoided.

Primary Subject area Neonatal-Perinatal Medicine Background Preterm birth outcome studies and clinical follow-up have traditionally focused on neurodevelopment. We previously showed in a selected sample of parents that they also valued other types of outcomes. Objectives This study aimed to validate these findings in a more diverse cohort by examining parental perspectives about the positive and negative aspects of their very preterm child’s health and development in relation to level of neurodevelopment impairment (NDI). Design/Methods Parents of children born &lt; 29 weeks gestational age in 2016-2018 and seen at two Canadian neonatal follow-up clinics were invited to complete an online survey about their level of agreement with statements about their child’s health, development, and well-being. Parental responses in relation to their child’s level of NDI were examined using Kruskal-Wallis and chi-square for trends tests. Results 199 parental responses were obtained for 165 children (65% of eligible children). Of these children, 52%, 27% and 21% had, respectively, no, mild to moderate, and severe NDI. Development was the most common source of concerns (49%), followed by the child’s future (35%), and physical health (35%). Parents of children with severe NDI were more likely to express concerns than those with mild to moderate or no NDI. Parents rated their child’s health relatively high with a median score of 8/10 (range 3-10). Children with no NDI were given higher scores than those with NDI (p = 0.004). Regardless of level of NDI, almost all parents agreed with their child being happy (p = 1.000) and having a positive personality (p = 0.207). Figure 1 shows that parental concerns increased with level of NDI. Conclusion Parents of preterm children have a balanced perspective on their child’s outcome. Integrating their views when developing core sets of important outcomes for neonatal follow-up is critical.
