Early-Life Slow Enteral Feeding Progression Pattern Is Associated with Longitudinal Head-Size Growth Faltering and Neurodevelopmental Impairment Outcomes in Extremely Preterm Infants.

ABSTRACT:

Objective

To determine whether feeding progression patterns in the first eight postnatal weeks, depicted by clustering analysis of daily enteral feeding volume, are associated with longitudinal head-circumference (HC) growth and neurodevelopmental outcomes in extremely preterm (EP) infants.

Methods

200 infants who were admitted at gestational ages 23-27 weeks between 2011 and 2018; survived to discharge; and underwent longitudinal HC growth measurements at birth, term-equivalent age (TEA), corrected age (CA) 6-month, 12-month, and 24-month; and neurodevelopmental assessment using the Bayley Scales of Infant Development at CA 24 months were included for analysis.

Results

kmlShape analysis identified two distinct enteral feeding progression patterns: fast progression in 131 (66%) infants and slow progression in 69 (34%) infants. Compared to the fast progression group, the slow progression group showed significantly lower daily enteral volumes after day 13, was older in postnatal age reaching full feeding, had a higher rate of Delta z scores of HC (zHC) < -1 (p < 0.001) between birth and TEA, and displayed lower longitudinal zHC from TEA to CA 24 months. The slow progression group also showed higher rates of microcephaly [42% vs. 16%, p < 0.001; adjusted odd ratio (aOR): 3.269, p = 0.001] and neurodevelopmental impairment (NDI) (38% vs. 19%, p = 0.007; aOR: 2.095, p = 0.035) at CA 24 months. For NDI, the model including feeding progression patterns showed a lower Akaike information criterion score and a better goodness of fit than the model that did not include feeding patterns.

Conclusion

Characterizing feeding progression pattern may help identify EP infants at high-risk of head-size growth faltering and NDI at early childhood.

Project description:BackgroundEarly progression of feeding could influence the development of the gut microbiome.MethodsWe collected fecal samples from extremely preterm infants randomized to receive either early (feeding day 2) or delayed (feeding day 5) feeding progression. After study completion, we compared samples obtained at three different time points (week 1, week 2, and week 3) to determine longitudinal differences in specific taxa between the study groups using unadjusted and adjusted negative binomial and zero-inflated mixed models. Analyses were adjusted for a mode of delivery, breastmilk intake, and exposure to antibiotics.ResultsWe analyzed 137 fecal samples from 51 infants. In unadjusted and adjusted analyses, we did not observe an early transition to higher microbial diversity within samples (i.e., alpha diversity) or significant differences in microbial diversity between samples (i.e., beta diversity) in the early feeding group. Our longitudinal, single-taxon analysis found consistent differences in the genera Lactococcus, Veillonella, and Bilophila between groups.ConclusionsDifferences in single-taxon analyses independent of the mode of delivery, exposure to antibiotics, and breastmilk feeding suggest potential benefits of early progression of enteral feeding volumes. However, this dietary intervention does not appear to increase the diversity of the gut microbiome in the first 28 days after birth.Trial registrationClinicalTrials.gov identifier: NCT02915549.ImpactEarly progression of enteral feeding volumes with human milk reduces the duration of parenteral nutrition and the need for central venous access among extremely preterm infants. Early progression of enteral feeding leads to single-taxon differences in longitudinal analyses of the gut microbiome, but it does not appear to increase the diversity of the gut microbiome in the first 28 days after birth. Randomization in enteral feeding trials creates appealing opportunities to evaluate the effects of human milk diets on the gut microbiome.

Project description:ImportanceObservational studies have associated patent ductus arteriosus (PDA) ligation among preterm infants with adverse neonatal outcomes and neurodevelopmental impairment in early childhood, with a resultant secular trend away from surgical treatment. However, to our knowledge, studies have inadequately addressed sources of residual bias, including survival bias and major neonatal morbidities arising before exposure to ligation.ObjectiveEvaluate the association between PDA ligation vs medical management and neonatal and neurodevelopmental outcomes.Design, setting, and participantsThis retrospective cohort study of preterm infants younger than 28 weeks gestational age born between January 1, 2006, and December 31, 2012, with clinical and echocardiography diagnoses of hemodynamically significant PDA was conducted at 3 tertiary neonatal intensive care units and affiliated follow-up programs.ExposureSurgical ligation vs medical management.Main outcomes and measuresThe primary outcome was a composite of death or neurodevelopmental impairment (NDI) at 18 to 24 months corrected age. Secondary outcomes included death before discharge, NDI, moderate-severe chronic lung disease, and severe retinopathy of prematurity. Multivariable logistic regression analysis was used to adjust for perinatal and postnatal confounders.ResultsOf 754 infants with hemodynamically significant PDA (mean [standard deviation] gestational age 25.7 [1.2] weeks and birth weight 813 [183] grams), 184 (24%) underwent ligation. Infants who underwent ligation had a higher frequency of morbidities before PDA closure, including sepsis, necrotizing enterocolitis, and a dependence on mechanical ventilation. After adjusting for perinatal characteristics and preligation morbidities, there was no difference in the odds of death or NDI (adjusted odds ratio (aOR), 0.83; 95% CI, 0.52-1.32), NDI (aOR, 1.27; 95% CI, 0.78-2.06), chronic lung disease (aOR, 1.36; 95% CI, 0.78-2.39) or severe retinopathy of prematurity (aOR, 1.61; 95% CI, 0.85-3.06). Ligation was associated with lower odds of mortality (aOR, 0.09; 95% CI, 0.04-0.21).Conclusions and relevancePatent ductus arteriosus ligation among preterm neonates younger than 28 weeks gestational age was not associated with the composite outcome of death or NDI, and there were no differences in chronic lung disease, retinopathy of prematurity, or NDI among survivors. Mortality was lower among infants who underwent ligation, though residual survival bias could not be excluded. Previously reported associations of ligation with increased morbidity may be because of bias from confounding by indication.

Project description:BackgroundAmong infants born prematurely, competence at oral feeding is necessary for growth and hospital discharge. Extremely preterm (EP) infants (28 weeks of gestational age [GA]) are at risk for a variety of medical complications, which can limit the infant's capacity to develop oral feeding competence.ObjectiveThis study examined feeding progression by assessing timing of acquisition of five early feeding milestones among EP infants and the impact of immaturity and medical complications.DesignA chart review was conducted for 94 EP infants who participated in a larger longitudinal randomized study. Feeding progression was defined as infants' postmenstrual age (PMA) at five milestones: first enteral feeding, full enteral feeding, first oral feeding, half oral feeding, and full oral feeding. GA at birth and five medical complications (neurological risk, bronchopulmonary dysplasia, necrotizing enterocolitis, patent ductus arteriosus, and gastroesophageal reflux disease) were used as potential factors influencing the feeding progression. Linear mixed models were used to examine feeding progression across the milestones and contributions of GA at birth and five medical complications on the progression, after controlling for milk type as a covariate.ResultEP infants gradually achieved feeding milestones; however, the attainment of the feeding milestones slowed significantly for infants with younger GA at birth and the presence of medical complications, including neurological risk, bronchopulmonary dysplasia, necrotizing enterocolitis, and patent ductus arteriosus but not gastroesophageal reflux disease. Milk type was a significant covariate for all analyses, suggesting that infants fed with breast milk achieved each of five milestones earlier than formula-fed infants.DiscussionImproved understanding of the timing of essential feeding milestones among EP infants and the contribution of specific medical conditions to the acquisition of these milestones may allow for more targeted care to support feeding skill development.
