Abstract
OBJECTIVE Pediatric nonalcoholic fatty liver disease (NAFLD) is a growing problem, but its underlying mechanisms are poorly understood. We used transcriptomic reporter cell assays to investigate differences in transcriptional signatures induced in hepatocyte reporter cells by the sera of children with and without NAFLD. METHODS We studied serum samples from 45 children with NAFLD and 28 children without NAFLD. The sera were used to induce gene expression in cultured HepaRG cells and RNA-sequencing was used to determine gene expression. Computational techniques were used to compare gene expression patterns. RESULTS Sera from children with NAFLD induced the expression of 195 genes that were significantly differentially expressed in hepatocytes compared to controls with obesity. NAFLD was associated with increased expression of genes promoting inflammation, collagen synthesis, and extracellular matrix remodeling. Additionally, there was lower expression of genes involved in endobiotic and xenobiotic metabolism, and downregulation of peroxisome function, oxidative phosphorylation, and xenobiotic, bile acid, and fatty acid metabolism. A 13-gene signature, including upregulation of TREM1 and MMP1 and downregulation of CYP2C9, was consistently associated with all diagnostic categories of pediatric NAFLD. CONCLUSION The extracellular milieu of sera from children with NAFLD induced specific gene profiles distinguishable by a hepatocyte reporter system. Circulating factors may contribute to inflammation and extracellular matrix remodeling and impair xenobiotic and endobiotic metabolism in pediatric NAFLD.

Abstract
LEARNING OUTCOME To learn how skimmed human milk (SHM) can be used in infants with chylothorax to support adequate weight gain and nutrition while receiving human milk. BACKGROUND Traditional nutrition management for chylothorax is to limit long-chain triglycerides (LCTs) and provide a diet high in medium-chain triglycerides (MCTs). Transition from human milk to formula has been required to provide the ratio of MCT to LCT required to stop the accumulation of chyle. Although SHM may provide the right fat content for a baby with chylothorax, previous studies have shown slow growth in infants receiving SHM. OBJECTIVE To demonstrate that infants receiving SHM fortified with high-MCT infant formula will have age appropriate growth without re-accumulation of chyle. DESIGN/METHODS Between 2017 and 2019, term infants with the diagnosis of chylothorax who were previously receiving human milk and transitioned to fortified SHM were monitored for growth and reaccumulation of chyle. RESULTS The six infants who were prescribed fortified SHM with high-MCT infant formula using standardized recipes did not show reaccumulation of chyle and showed positive weight gain in five of the six study patients. The infants gained a mean weight of 30.5 g/day (±19.5), and their weight z scores improved by a mean of +0.29 (±0.33). CONCLUSIONS Fortified SHM is a safe treatment option that can provide adequate nutrition for the infant with chylothorax to gain weight appropriately for age.

Abstract
OBJECTIVE To describe neonatal intensive care unit (NICU) medical interventions and NICU mortality by birth weight and major anomaly types for infants with trisomy 13 (T13) or 18 (T18). STUDY DESIGN Retrospective cohort analysis of infants with T13 or T18 from 2005 to 2012 in the Pediatrix Medical Group. We classified infants into three groups by associated anomaly type: neonatal surgical, non-neonatal surgical and minor. Outcomes were NICU medical interventions and mortality. RESULTS 841 infants were included from 186 NICUs. NICU mortality varied widely by anomaly type and birth weight, from 70% of infants <1500 g with neonatal surgical anomalies to 31% of infants ⩾2500 g with minor anomalies. Infants ⩾1500 g without a neonatal surgical anomaly comprised 66% of infants admitted to the NICU; they had the lowest rates of NICU medical interventions and NICU mortality. CONCLUSIONS Risk stratification by anomaly type and birth weight may help provide more accurate family counseling for infants with T13 and T18.

Abstract
The cholesterol molecule is at the center of the pathophysiology of many vascular diseases. Whole-body cholesterol pools are maintained by a balance of endogenous synthesis, dietary absorption and elimination from our bodies. While the cellular aspects of cholesterol metabolism received significant impetus from the seminal work of Goldstein and Brown investigating LDL receptor trafficking, how dietary cholesterol was absorbed and eliminated was relatively neglected. The identification of the molecular defect a rare human disorder, Sitosterolemia, led to elucidation of a key mechanism of how we regulate the excretory pathway in the liver and in the intestine. Two proteins, ABCG5 and ABCG8, constitute a heterodimeric transporter that facilitates the extrusion of sterols from the cell into the biliary lumen, with a preference for xenosterols. This mechanism explained how dietary xenosterols are prevented from accumulating in our bodies. In addition, this disease has also highlighted the potential harm of xenosterols; macrothrombocytopenia, liver disease and endocrine disruption are seen when xenosterols accumulate. Mouse models of this disease suggest that there are more dramatic alterations of physiology, suggesting that these highly conserved mechanisms have evolved to prevent these xenosterols from accumulating in our bodies.

Abstract
BACKGROUND The aim of this study was to determine the tube-related complications and feeding outcomes of infants discharged home from the neonatal intensive care unit (NICU) with nasogastric (NG) tube feeding or gastrostomy (G-tube) feeding. MATERIALS AND METHODS We performed a chart review of 335 infants discharged from our NICU with home NG tube or G-tube feeding between January 2009 and December 2013. The primary outcome was the incidence of feeding tube-related complications requiring emergency department (ED) visits, hospitalizations, or deaths. Secondary outcome was feeding status at 6 months postdischarge. Univariate and multivariate analyses were conducted. RESULTS There were 322 infants discharged with home enteral tube feeding (NG tube, n = 84; G-tube, n = 238), with available outpatient data for the 6-month postdischarge period. A total of 115 ED visits, 28 hospitalizations, and 2 deaths were due to a tube-related complication. The incidence of tube-related complications requiring an ED visit was significantly higher in the G-tube group compared with the NG tube group (33.6% vs 9.5%, P < .001). Two patients died due to a G-tube-related complication. By 6 months postdischarge, full oral feeding was achieved in 71.4% of infants in the NG tube group compared with 19.3% in the G-tube group ( P < .001). Type of feeding tube and percentage of oral feeding at discharge were significantly associated with continued tube feeding at 6 months postdischarge. CONCLUSION Home NG tube feeding is associated with fewer ED visits for tube-related complications compared with home G-tube feeding. Some infants could benefit from a trial home NG tube feeding.

Abstract
BACKGROUND Premature and critically ill infants receiving total parenteral nutrition (TPN) are at risk for dyslipidemia, and altered cholesterol levels in early life may contribute to later cardiovascular risk. Data regarding plasma cholesterol response to TPN in young infants are lacking. OBJECTIVE To determine the changes in plasma cholesterol levels during the first week of life in infants receiving TPN and a comparison group of infants who did not receive TPN during routine care. METHODS In a prospective, pilot cohort study, 38 neonates (30 TPN vs. 8 No-TPN) underwent serial blood sampling during the first week of life. Gas chromatography-mass spectrometry was used to measure cholesterol in plasma and TPN administered to study participants. RESULTS Baseline cholesterol level was similar between groups. In contrast to infants who did not receive TPN, cholesterol levels during the first week of life were significantly higher than baseline in infants receiving TPN (maximum cholesterol response 34% vs. 103% change from baseline, No-TPN vs. TPN, respectively, P = .036). After adjusting for cumulative cholesterol received by infants receiving TPN, maximum cholesterol response remained inversely related to gestational age and birth weight (P < .05). CONCLUSION Plasma cholesterol significantly increases during the first week of life in neonates receiving TPN. A higher cholesterol response was induced by TPN in infants of lower gestational age and birth weight.

Abstract
BACKGROUND Cyclic parenteral nutrition (PN) is used for both the treatment and prevention of parenteral nutrition-associated liver disease (PNALD). Early initiation of prophylactic cyclic PN may not be well tolerated in young neonates. Our objective was to test the hypothesis that prophylactic cyclic PN initiated prior to the onset of hyperbilirubinemia is associated with younger age at initiation, lower bilirubin levels, and similar rates of adverse events compared to therapeutic cyclic PN initiated after established cholestasis in surgical neonates. METHODS A retrospective review of infants with gastrointestinal disorders requiring surgical intervention who received cyclic PN 2006-2011 was performed. RESULTS Of the 43 infants eligible for analysis, 23 received prophylactic and 20 received therapeutic cyclic PN. Infants in both groups were comparable in demographics, surgical diagnoses, and illness severity. At initiation of cyclic PN, infants with prophylactic cyclic PN were significantly younger in chronologic (P = .003) and postmenstrual age (P = .029). Prophylactic cyclic PN was associated with a significantly lower incidence of hyperbilirubinemia (P = .001), lower maximum conjugated bilirubin (P < .0001), and lower last checked conjugated bilirubin (P = .032) compared to the therapeutic cyclic PN. The incidence of hypoglycemia, hyperglycemia, and hypertriglyceridemia was similar for the 2 groups. CONCLUSIONS There may be a potential benefit to initiating cyclic PN prior to the development of hyperbilirubinemia in surgical neonates. Early initiation of prophylactic cyclic PN does not appear to increase the risk for adverse events.
