Objective: Determine short-term outcomes following peritoneal drain (PD), laparotomy (LAP) after PD (PD-LAP), and LAP in extremely low birth weight (ELBW) infants with spontaneous intestinal perforation (SIP)., Study Design: ELBW infants with SIP were identified using the Children's Hospitals Neonatal Database. Mortality and length of stay (LOS) were compared among groups., Results: Of 729 SIP infants from 6/2010-12/2016, 383(53%) received PD, 61(8%) PD-LAP, and 285(39%) LAP. PD infants had lower GA at birth, at SIP diagnosis and upon admission than PD-LAP or LAP; and higher sepsis rates than LAP. Bivariate analysis and Kaplan-Meier survival estimates suggested PD had increased mortality vs. PD-LAP and LAP (27%, 11.5%, and 15.8% respectively, p < 0.001). However, surgical approach was not significantly associated with mortality in multivariable analysis accounting for GA and illness severity. LOS did not differ by surgical approach., Conclusions: In ELBW infants with SIP, mortality, and LOS are independent of the initial surgical approach., Competing Interests: Competing interests: The authors declare no competing interests. Ethics: IRB approval was obtained at each participating site prior to entering data into CHND. For analysis of de-identified data, the Stanley Manne Research Center (2011-14673) reviewed and approved this work. The study was performed in accordance with the Declaration of Helsinki., (© 2024.

Objective: Quantify blood fatty acids and growth outcomes in preterm infants fed the exclusive human milk diet., Methods: A prospective cohort study of 30 infants 24-34 weeks gestation and ≤1250 g fed the exclusive human milk diet. Blood fatty acids were quantified at two time points. Comparisons were made using two-sample t-tests and Wilcoxon rank sum., Results: Donor human milk-fed (n = 12) compared to mother's own milk-fed infants (n = 18) from birth to after 28 days of life, had an increased interval change of linoleic to docosahexaenoic acid ratio (5.5 vs. -1.1 mole percent ratio, p = 0.034). Docosahexaenoic and eicosapentaenoic acid interval changes were similar between groups. The arachidonic acid change was similar between groups (-2.3 vs. -0.9 mole percent, p = 0.37), however, both experienced a negative change across time. At 36 weeks postmenstrual age, growth velocities were similar for groups., Conclusion: An exclusive human milk diet maintains birth docosahexaenoic and eicosapentaenoic acid concentrations. However, the postnatal deficit in arachidonic acid was not prevented., (© 2023. The Author(s), under exclusive licence to Springer Nature America, Inc.)

Fortification of human milk is the standard of care for very low birth weight (VLBW) infants and is required to support adequate postnatal growth and development. Achieving adequate growth velocity and preventing growth faltering is critical for the developing neonatal brain and optimizing long-term neurodevelopmental outcomes. Mother's milk is the gold standard nutrition to feed preterm infants, however, it does not provide the nutrients needed to support the growth of VLBW infants. After the decision is made to use mother's milk (if available) or alternatively, donor human milk, many dilemmas exist with regards to additional treatment decisions surrounding the type of fortification to use, when to fortify, and the duration of fortification. In this article, we will review the differences in mother's milk compared to donor milk, the different types of human milk fortifiers, the optimal timing of fortification, and discuss when to discontinue human milk fortification., (© 2022.

Intestinal failure in neonatal and pediatric populations can be debilitating for patients and difficult to manage for clinicians. Management strategies include referral to an intestinal rehabilitation center, small volume trophic feeds to stimulate the intestine with cautious advancement of enteral nutrition using a standardized and evidence-based feeding protocol, and supplemental parenteral nutrition to optimize an infant's growth and nutrition. In this review, we discuss the causes of intestinal failure, parenteral nutrition strategies, enteral feeding initiation and advancement protocols, as well as the challenges in feeding an infant with intestinal failure., (© 2022.

Objectives: To evaluate variability in antibiotic duration for necrotizing enterocolitis (NEC) and associated clinical outcomes., Study Design: Five-hundred ninety-one infants with NEC (315 medical; 276 surgical) were included from 22 centers participating in Children's Hospitals Neonatal Consortium (CHNC). Multivariable analyses were used to determine predictors of variability in time to full feeds (TFF) and length of stay (LOS)., Results: Median (IQR) antibiotic duration was 12 (9, 17) days for medical and 17 (14, 21) days for surgical NEC. Wide variability in antibiotic use existed both within and among centers. Duration of antibiotic therapy was associated with longer TFF in both medical (OR 1.04, 95% CI [1.01, 1.05], p < 0.001) and surgical NEC (OR 1.02 [1, 1.03] p = 0.046); and with longer LOS in medical (OR 1.03 [1.02, 1.04], p < 0.001) and surgical NEC (OR 1.01 [1.01, 1.02], p = 0.002)., Conclusion: Antibiotic duration for both medical and surgical NEC remains variable within and among high level NICUs., (© 2022.

Objective: The objective of this multi-center study was to compare, in infants ≤1250 g birth weight (BW) with neurodevelopmental assessment at 18-22 months of corrected age (CA), whether their neurodevelopmental outcomes differed based on exposure to an exclusive human milk-based (HUM) or to a bovine milk-based fortifier and/or preterm formula (BOV)., Study Design: Retrospective multi-center cohort study of infants undergoing neurodevelopmental assessment as to whether HUM or BOV exposure related to differences in outcomes of infants at 18-22 months CA, using the Bayley Scales of Infant Development III (BSID-III). BSID-III cognitive, language, and motor scores were adjusted for BW, sex, study site, and necrotizing enterocolitis., Results: 252 infants from 6 centers were included. BSID-III cognitive scores were higher in the HUM group (96.5 ± 15.1 vs 89.6 ± 14.1, adjusted p = 0.0001). Mean BSID-III language scores were 85.5 ± 15.0 in HUM and 82.2 ± 14.1 in BOV (adjusted p = 0.09). Mean BSID-III motor scores were 92.9 ± 11.7 in HUM and 91.4 ± 14.6 in BOV (adjusted p = 0.32)., Conclusion: In this cohort of infants undergoing neurodevelopmental assessment, infants receiving HUM diet had significantly higher cognitive BSID-III scores at 18-22 months CA. Further investigation is needed of this potential for HUM to positively influence infant cognitive outcomes., (© 2022. The Author(s).)

Objective: Small for gestational age (SGA) preterm infants (PT) are at greatest risk for growth failure. Our objective was to assess the impact of an exclusive human milk diet (HUM) on growth velocities and neonatal morbidities from birth to discharge in a SGA population., Study Design: Multicenter, retrospective cohort study, subgroup analysis of SGA PT comparing a cow's milk diet (CMD) with HUM diet., Results: At birth 420 PT were classified as SGA (197 CMD group, 223 HUM group). Demographics and anthropometric measurements were similar. HUM group PT showed improvement in length Z score at discharge (p = 0.024) and reduction in necrotizing enterocolitis (NEC) (p = 0.004)., Conclusion: SGA PT fed a HUM diet had significantly decreased incidence of NEC, surgical NEC, and late-onset sepsis. Due to concerns about growth in a HUM diet, it is reassuring SGA infants fed the HUM diet had similar growth to CMD diet with trends toward improvement., (© 2021. The Author(s).)

Objective: To evaluate the growth of premature infants fed a postdischarge diet of human milk (HM) complemented with transitional formula (TF) as compared with those fed TF only., Study Design: In this prospective cohort study, 51 infants' diets and anthropometrics were collected at discharge and at 12-15 months corrected gestational age., Results: Post discharge, infants in both groups exhibited similar growth velocities and changes in z-scores. The duration of infants' HM consumption was not correlated with weight gain (r = -0.25, p = 0.26). The duration of complementary TF feeds also did not correlate with increased growth (r = -0.11, p = 0.44). Both groups achieved catch-up growth and displayed growth velocities that significantly exceeded the upper limit of the World Health Organization (WHO) weight growth standard (p < 0.001)., Conclusions: Preterm infants receiving HM and complementary TF post discharge had growth velocities at or exceeding weight gain projected by the WHO growth standard for term infants.
