Abstract
Intrapartum hypoxia-ischemia leading to neonatal encephalopathy (NE) results in significant neonatal mortality and morbidity worldwide, with > 85% of cases occurring in low- and middle-income countries (LMIC). Therapeutic hypothermia (HT) is currently the only available safe and effective treatment of HIE in high-income countries (HIC); however, it has shown limited safety or efficacy in LMIC. Therefore, other therapies are urgently required. We aimed to compare the treatment effects of putative neuroprotective drug candidates following neonatal hypoxic-ischemic (HI) brain injury in an established P7 rat Vannucci model. We conducted the first multi-drug randomized controlled preclinical screening trial, investigating 25 potential therapeutic agents using a standardized experimental setting in which P7 rat pups were exposed to unilateral HI brain injury. The brains were analysed for unilateral hemispheric brain area loss after 7 days survival. Twenty animal experiments were performed. Eight of the 25 therapeutic agents significantly reduced brain area loss with the strongest treatment effect for Caffeine, Sonic Hedgehog Agonist (SAG) and Allopurinol, followed by Melatonin, Clemastine, ß-Hydroxybutyrate, Omegaven, and Iodide. The probability of efficacy was superior to that of HT for Caffeine, SAG, Allopurinol, Melatonin, Clemastine, ß-hydroxybutyrate, and Omegaven. We provide the results of the first systematic preclinical screening of potential neuroprotective treatments and present alternative single therapies that may be promising treatment options for HT in LMIC.

A Comparison of Smoflipid® and Intralipid® in the Early Management of Infants with Intestinal Failure. J Pediatr Surg 2020; 55:153-157.

Abstract
PURPOSE Cholestasis is problematic for infants with intestinal failure (IF). The soy-based lipid Intralipid® (IL) has been implicated. An alternative, Smoflipid® (SMOF), is increasingly used. However, its role in cholestasis prevention is unclear. This study compares the incidence and degree of cholestasis between infants with IF receiving SMOF or IL. METHODS Infants with IF receiving SMOF or IL during the first 8 weeks of parenteral nutrition (PN) support between 2014 and 2017 were reviewed. Clinical characteristics, cholestasis incidence (conjugated bilirubin (Cbili) >2 mg/dL for >2 weeks), and nutritional parameters were compared using Welch's t-test. RESULTS 91% (21/23) of IL and 76% (16/21) of SMOF babies became cholestatic (p = 0.18). There was no significant difference in median peak Cbili, but SMOF babies normalized more quickly (p = 0.04). Median z-scores for weight were similar throughout the study. SMOF patients getting full PN had a lower incidence of cholestasis compared to IL patients (78% vs. 92%, p = 0.057), but those with cholestasis had similar peak Cbili, time to resolution, and growth. CONCLUSION Early use of Smoflipid® did not reduce the incidence of cholestasis compared to Intralipid® in infants with IF, but hyperbilirubinemia did resolve more quickly. SMOF may be most beneficial for infants tolerating no enteral nutrition. LEVEL OF EVIDENCE Level III Retrospective Comparative Treatment Study. TYPE OF STUDY Retrospective Review.

A Retrospective Analysis of the Effect of Combination of Pure Fish Oil with Third Generation Lipid Emulsion on Liver Function in Children on Long-Term Parenteral Nutrition. Nutrients 2019; 11:nu11102495. [PMID: 31627315 PMCID: PMC6836066 DOI: 10.3390/nu11102495] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Revised: 10/06/2019] [Accepted: 10/10/2019] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Deterioration of liver function, or intestinal failure-associated liver disease, is often observed in long-term parenterally fed children. Fish oil-based intravenous lipids have been reported to play a role in the prevention and treatment of intestinal failure associated liver disease. METHODS This retrospective analysis included 40 pediatric patients, (20 male and 20 female), median age 38 months (range 1.5-200 months) on long-term (≥1 month) parenteral nutrition who received the parenteral mixtures containing a combination of a third-generation lipid emulsion and pure fish oil because of laboratory liver function abnormalities. The total dose of fish oil from both emulsions for each patient exceeded 0.5 g/kg/day. Data from visits in an outpatient clinic were retrospectively analyzed using the Wilcoxon test, Mann-Whitney test, and Spearman correlation test. RESULTS The median time of therapy was 149 days (range 28-418 days). There was a decrease of median total and direct (conjugated) bilirubin concentration from 22.23 µmol/L (range 3.42-243 µmol/L) to 10.26 µmol/L (range 3.42-180.58 µmol/L; p < 0.005) and 8.55 (range 1.71-212.04 µmol/L) to 6.84 µmol/L (range 1.71-150.48 µmol/L; p < 0.007) respectively. A significant decrease in median alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl transferase was also observed. In 11 patients bilirubin concentrations increased or remained unchanged. When compared to the patients who responded to the combination therapy, the patients who did not respond received parenteral nutrition for a longer time prior to the start of the therapy (51 vs. 30 months; p < 0.05). CONCLUSIONS The mixture of an intravenous lipid emulsion containing soybean oil, medium-chain triglycerides, olive oil, and fish oil with the addition of pure fish oil emulsion may be helpful in the treatment of liver complications in children on long-term parenteral nutrition.

Abstract
BACKGROUND/OBJECTIVES The precise role of fish oil-based lipid emulsions (FBL=any lipid emulsion containing any amount of fish oil) and soy oil-based lipid emulsions (SBL=any lipid emulsion not containing fish oil or containing at least 50% soy oil) in neonatal parenteral nutrition (PN) needs to be explored. SUBJECTS/METHODS The PubMed, MedLine and Google Scholar databases were searched for randomised control trials in which PN with FBL and SBL was the only difference between intervention and control groups. Methodological quality was assessed based on the Cochrane handbook for systemic reviews and Jadad's score. Revman 5.2 software was used for meta-analysis. RESULTS Of 420 trials, 25 met the inclusion criteria. The aggregate results showed that both FBLs and SBLs are beneficial. FBLs were associated with significantly lower incidences of cholestasis (relative risk (RR)=0.50; 95% confidence interval (CI)=0.27-0.92, P=0.03) compared with SBLs. FBLs also had a tendency to improve the rates of weight gain, increase in head circumference and the time to regain birth weight (mean difference (MD)=0.24; 95% CI=-0.63-0.15). SBLs were associated with reduced duration of respiratory support (MD=2.22, 95% CI=0.35-4.09, P=0.02) and mortality rate in the first 28 days (RR=1.24, 95% CI=-0.72-2.13). CONCLUSIONS Both FBLs and SBLs are beneficial for neonatal PN. FBLs reduce cholestasis, and SBLs reduce the duration of respiratory support.

Abstract
Fat is an important macronutrient in the human diet. For patients with intestinal failure who are unable to absorb nutrients via the enteral route, intravenous lipid emulsions play a critical role in providing an energy-dense source of calories and supplying the essential fatty acids that cannot be endogenously synthesized. Over the last 50 y, lipid emulsions have been an important component of parenteral nutrition (PN), and over the last 10-15 y many new lipid emulsions have been manufactured with the goal of improving safety and efficacy profiles and achieving physiologically optimal formulations. The purpose of this review is to provide a background on the components of lipid emulsions, their role in PN, and to discuss the lipid emulsions available for intravenous use. Finally, the role of parenteral fat emulsions in the pathogenesis and management of PN-associated liver disease in PN-dependent pediatric patients is reviewed.

Abstract
OBJECTIVE Management of short bowel syndrome (SBS) has significantly evolved recently. We present our single-center, 25-year experience focusing on the implementation of a refined multidisciplinary SBS care protocol. METHODS This is a retrospective review of the patients with SBS treated at our tertiary center from 1988 to 2014, with either <25% short bowel remaining or duration of parenteral nutrition (PN) >3 months. Patients with primary intestinal motility disorders were excluded. Clinical characteristics, including intestinal anatomy, markers of cholestasis, and catheter-related infections (CRIs), were analyzed. The implementation of a refined modern uniform management protocol in 2009 divided the cohort into 2 subgroups, whose outcomes are compared. RESULTS Forty-eight patients with SBS were identified (median gestational age 33 weeks). Of them, 22 were born between 2009 and 2014. The main causes of SBS were necrotizing enterocolitis (46%) and midgut volvulus (23%). Median remaining small bowel length was 36 cm. The overall survival was 23 of 26 (88%) before 2009 and 21 of 22 (95%) thereafter, whereas none were transplanted. Duration of PN shortened from a median of 15 to 6 months (P = 0.0015) in the latter cohort, whereas frequency of autologous intestinal reconstruction surgery (31%) remained unchanged. Frequency of neonatal cholestasis was similar in both groups (75%), but cleared in all after 2009. Before 2009, 2 patients died of progressive cholestatic liver failure. The CRI rates decreased from 1.7 to 0.7 per 1000 catheter-days between 2000-2008 and 2009-2014, respectively (P = 0.0178). CONCLUSIONS Uniform refined multidisciplinary approach decreased the duration of PN and CRI rates with high transplant-free survival and avoidance of liver failure, although the frequency of transient neonatal cholestasis remained unchanged.

Abstract
BACKGROUND Soybean oil lipid emulsion may compromise immune function and promote hepatic damage due to its composition of long-chain fatty acids, phytosterols, high proportion of ω-6 fatty acids, and low α-tocopherol levels. Combination lipid emulsions have been developed using medium-chain triglyceride oil, fish oil, and/or olive oil, which provide adequate essential fatty acids, a smaller concentration of ω-6 fatty acids, and lower levels of phytosterols. The purpose of this systematic review is to determine if combination lipid emulsions have a more favorable impact on bilirubin levels, triglyceride levels, and incidence of infection compared with soybean oil lipid emulsions in children receiving parenteral nutrition. METHODS This study comprises a systematic review of published studies. Data were sufficient and homogeneous to conduct a meta-analysis for total bilirubin and infection. RESULTS Nine studies met the inclusion criteria. Meta-analysis showed that combination lipid emulsion decreased total bilirubin by a mean difference of 2.09 mg/dL (95% confidence interval, -4.42 to 0.24) compared with soybean oil lipid emulsion, although the result was not statistically significant (P = .08). Meta-analysis revealed no statistically significant difference in incidence of infection between the combination lipid emulsion and the soybean oil lipid emulsion groups (P = .846). None of the 4 studies that included triglyceride as an outcome detected a significant difference in triglyceride levels between the combination lipid emulsion and soybean oil lipid emulsion groups. CONCLUSION There is inadequate evidence that combination lipid emulsions offer any benefit regarding bilirubin levels, triglyceride levels, or incidence of infection compared with soybean oil lipid emulsions.

Abstract
Parenteral nutrition (PN) is necessary for infants unable to receive adequate calories enterally due to prematurity, decreased bowel length, or functional intestinal disorders. While PN can be life saving, its use is associated with significant risks of sepsis from catheter-associated infections and progressive liver dysfunction from prolonged use. The preterm infant population is at highest risk for these complications due to the presence of multiple comorbidities and immaturity of the biliary system. Strong data has implicated parenteral lipids in the multifactorial pathogenesis of PN-associated liver disease (PNALD). However, lipids are essential in early infant development, particularly in the neurocognitive development of preterm infants. Substitution of the lipid source from soybean oil to fish oil has emerged as a safe and efficacious treatment of PNALD, with marked improvements in morbidity and mortality. Knowledge of the developmental needs and physiologic limitations of preterm infants is crucial to optimizing parenteral lipid administration to nurture growth, and minimize and treat associated complications. The purpose of this review is to provide an overview of lipid requirements of the preterm infant and discuss the role of parenteral lipid emulsions in the management of PNALD and other diseases of prematurity.

Abstract
PURPOSE OF REVIEW The liver adaptively responds to extra-intestinal and intestinal inflammation. In recent years, the role of the autonomic nervous system, intestinal failure and gut microbiota has been investigated in the development of hepatic, intestinal and extra-intestinal disease. RECENT FINDINGS The autonomic nervous system can be stimulated via enteral fat leading to cholecystokinin release, stimulating receptors in the gut and in the brain. This promotes bowel integrity, dampening the inflammatory response to food antigens. Consensus exists that intravenously administered long-chain fatty acids can cause liver damage but randomized-controlled trials are lacking. Disruption of the enterohepatic circulation of bile salts can give rise to cholestasis and nonalcoholic fatty liver disease, which may progress to fibrosis and cirrhosis. Reduced intestinal availability of bile salts reduces stimulation of the farnesoid X receptor. This may induce hepatic bile salt overload and associated hepatotoxicity through reduced action of intestinal fibroblast growth factor 19. Evidence is put forward to suggest that the intestinal microbiota is associated with liver abnormalities. SUMMARY Enteral lipids reduce inflammation and liver damage during stress or systemic inflammation, whereas parenteral lipid is associated with liver damage. Maintaining the enterohepatic circulation of bile salts limits hepatic cholestasis through an farnesoid X receptor feedback pathway. Changes in gut microbiota composition may induce liver disease.

Abstract
INTRODUCTION A parenteral lipid emulsion (LE), used as a key source of energy, essential fatty acids (FAs), and fat-soluble vitamins, is an integral part of a parenteral nutrition (PN) regimen. The conventional LEs, such as soybean oil (SO)-based emulsions, have caused concerns about the potential adverse effects involving oxidative stress, inflammation, and immune response probably because of undesirable FA composition. AREAS COVERED Recently, alternative LEs, optimizing the FA composition with partial substitution of SO with medium-chain triglyceride (MCT), olive oil (OO), and fish oil (FO), have been developed and applied in clinical practice. This review summarizes the characteristics and beneficial clinical effects of alternative parenteral LEs in critically ill, pediatric, and long-term PN patients. EXPERT OPINION More clinical data from sufficiently high-powered studies are required to characterize the integral biological properties of alternative LEs for further selection to fit individual needs and disease characteristics. Simultaneously, potential lipid sources with desirable FA compositions and biological properties should be selected to develop new therapeutic LEs. As supplements to current parenteral lipids, the new LEs with different therapeutic effects are expected to fit specified subpopulations of patients with different diseases. Great efforts should be devoted to the development of parenteral LEs.

Abstract
BACKGROUND Studies have suggested that when intravenous (IV) soybean oil (SO) is replaced with fish oil (FO), direct hyperbilirubinemia is more likely to resolve. The necessary duration of FO has not been established. This study seeks to determine if 24 weeks of FO is an effective and safe therapy for intestinal failure-associated liver disease (IFALD). MATERIALS AND METHODS This is a clinical trial using patients with IFALD between the ages of 2 weeks and 18 years. SO was replaced with FO (1 g/kg/d) in 10 patients who were receiving most of their calories from parenteral nutrition (PN). Patients were compared with 20 historic controls receiving SO. SO for both groups was prescribed by the primary medical team at variable doses. The primary outcome was time to reversal of cholestasis. Secondary outcomes were death, transplant, and full enteral feeds. Safety measurements included growth, essential fatty acid deficiency, and laboratory markers to assess bleeding risk. RESULTS The Kaplan-Meier method estimated that 75% in the FO group would experience resolution of cholestasis by 17 weeks vs 6% in the SO group (P < .0001). When compared with the SO group, the FO group had decreased serum direct bilirubin concentrations at weeks 8 (P = .03) and 12, 16, 20, and 24 weeks (P < .0001). Although length z score at the end of the study increased in the FO group compared with baseline (P = .03), there were no significant differences in other outcomes. CONCLUSIONS A limited duration of FO appears to be safe and effective in reversing IFALD.

Abstract
BACKGROUND Cholestasis is a significant life-threatening complication in children on parenteral nutrition (PN). Strategies to prevent/treat PN-associated cholestasis (PNAC) and intestinal failure-associated liver disease (IFALD) have reached moderate success with little supporting evidence. Aims of this systematic review were (1) to determine the incidence of PNAC/IFALD in children receiving PN for ≥ 14 days and (2) to review the efficacy of measures to prevent/treat PNAC/IFALD. METHODS Of 4696 abstracts screened, 406 relevant articles were reviewed, and studies on children with PN ≥ 14 days and cholestasis (conjugated bilirubin ≥ 2 mg/dL) were included. Analyzed parameters were (1) PNAC/IFALD incidence by decade and by PN length and (2) PNAC/IFALD prevention and treatment (prospective studies). RESULTS Twenty-three articles (3280 patients) showed an incidence of 28.2% and 49.8% of PNAC and IFALD, respectively, with no evident alteration over the last decades. The incidence of PNAC was directly proportional to the length of PN (from 15.7% for PN ≤ 1 month up to 60.9% for PN ≥ 2 months; P < .0001). Ten studies on PNAC met inclusion criteria. High or intermediate-dose of oral erythromycin and aminoacid-free PN with enteral whey protein gained significant benefits in preterm neonates (P < .05, P = .003, and P < .001, respectively). None of the studies reviewed met inclusion criteria for treatment. CONCLUSIONS The incidence of PNAC/IFALD in children has no obvious decrease over time. PNAC is directly correlated to the length of PN. Erythromycin and aminoacid-free PN with enteral whey protein have shown to prevent PNAC in preterm neonates. There is a lack of high-quality prospective studies, especially on IFALD.

Abstract
Infants who are dependent on parenteral nutrition (PN) sometimes develop PN-associated cholestasis (PNAC). A compassionate use protocol, approved by the U.S. Food and Drug Administration and the institutional review board, guided enrollment of hospitalized infants with PNAC (<1 year of age, PN dependence for >3 weeks). Plasma concentrations of essential fatty acids were monitored before and after a soybean-based PN lipid, infused at 3 g/kg body weight/d, was replaced by an experimental fish oil-based intravenous fat emulsion (FO-IVFE) at 1.0 g/kg/d. All participants were born premature (n = 10; 20% male). At enrollment, infants were (mean ± SD) 86.5 ± 53.5 days of life and weighed 2.24 ± 0.87 kg; direct bilirubin was 5.5 ± 1.3 mg/dL. After treatment, blood concentrations significantly increased from baseline (P < .017) for circulating eicosapentaenoic acid (6.3 ± 3.0 to 147.8 ± 53.1 µg/mL), docosahexaenoic acid (20.7 ± 6.5 to 163.7 ± 43.4 µg/mL), pristanic acid (0.01 ± 0.01 to 0.17 ± 0.03 µg/mL), and phytanic acid (0.06 ± 0.03 to 0.64 ± 0.15 µg/mL). In contrast, total plasma ω-6 fatty acids (including linoleic acid) decreased (P < .017). The triene/tetraene ratio remained below the threshold value of 0.2 that defines ω-6 deficiency. No adverse effects were observed attributable to FO-IVFE. Discontinuation of FO-IVFE was typically due to infants (body weight 3.76 ± 1.68 kg) transitioning to enteral feeding rather than for resolution of hyperbilirubinemia (direct bilirubin 7.9 ± 4.8 mg/dL). These exploratory results suggest that FO-IVFE raises circulating ω-3 fatty acids in premature infants without development of ω-6 deficiency in the 8.3 ± 5.8-week time frame of this study.

Abstract
PURPOSE OF REVIEW Parenteral nutrition-associated liver disease (PNALD) is a major cause of morbidity and mortality in the parenteral nutrition-dependent population. Here, we review the most recent literature involving a fish oil-based lipid emulsion (FOLE) and its effects on PNALD. RECENT FINDINGS Vegetable oil-based lipid emulsions (VBLEs) contribute to PNALD. This may be due to parenteral phytosterols and/or the presence of pro-inflammatory mediators. Whereas a small reduction in the dose of VBLE does not appear to prevent PNALD, a significant reduction in the dose may reverse PNALD; however, it carries the risk of essential fatty acid deficiency. Furthermore, the impact of extreme lipid restriction on subsequent neurodevelopment is unknown. Combination lipid emulsions containing fish oil are associated with decreased bilirubin levels, though no studies compare these emulsions with the outcomes with FOLE alone. The utility of FOLE in the reversal of PNALD has been demonstrated and its administration does not lead to essential fatty acid deficiency. Furthermore, there is evidence that FOLE may prevent PNALD. CONCLUSION FOLE appears to be an efficacious treatment to reverse PNALD. However, more studies are necessary to determine if FOLE might also be beneficial in the prevention of PNALD. Future studies should additionally focus on the preterm infant population, as they represent a major population requiring parenteral nutrition support for survival.

Abstract
OBJECTIVE To determine factors leading to resolution of cholestasis in patients with parenteral nutrition-associated liver disease treated with fish oil-based lipid emulsion (FOLE). STUDY DESIGN Prospective observational study of 57 infants <6 months of age with parenteral nutrition-associated liver disease who received parenteral FOLE as monotherapy. RESULTS Median gestational age of subjects at birth was 28 weeks (range 22.7-39.5). Median conjugated bilirubin level at initiation of therapy with FOLE was 7.5 mg/dL (range 2.1-25). Resolution of hyperbilirubinemia (conjugated bilirubin <2.0 mg/dL) and survival to hospital discharge occurred in 47 (82.5%) infants. Median number of days to resolution of cholestasis was 35 (range 7-129). Ten infants (17.5%) died. Non-survivors showed a trend towards being more premature than survivors at birth (25.9 vs 29.1 weeks, P = .056). Infants with higher conjugated bilirubin at initiation of therapy (>10.0 compared with <5.0 mg/dL) had longer times to resolution (98 vs 56 days, P < .005). Time to resolution correlated inversely with gestational age at birth (r(2) = 0.14, P = .02) and directly with time to receive 100% calories enterally (r(2) = 0.12, P = .03). CONCLUSIONS Younger gestational age infants demonstrated higher degree of cholestasis, longer time to resolution of cholestasis, and increased mortality. Higher levels of cholestasis were associated with longer time to resolution. FOLE monotherapy led to resolution of cholestasis in all surviving infants.

Abstract
Considerable information has accumulated to show that DHA and EPA have unique roles that differ from other n-3 fatty acids and the n-6 fatty acids, with increasing understanding of the mechanisms through which these fatty acids reduce risk of disease. DHA and EPA regulate hepatic lipid and glucose metabolism, but are present in foods of animal origin, which are generally high in protein with variable triglycerides and low carbohydrate. Biological activity at intakes too low to provide significant amounts of energy is consistent with the definition of a vitamin for which needs are modified by life-stage, diet and genetic variables, and disease. Recent studies reveal that DHA may play a central role in co-coordinating complex networks that integrate hepatic glucose, fatty acid and amino acid metabolism for the purpose of efficient utilization of dietary protein, particularly during early development when the milk diet provides large amounts of energy from fat.

Abstract
Nutritional and metabolic damage is an important manifestation of severe liver disease and is significantly associated with prognosis. In this paper, we review nutritional and metabolic abnormalities and nutritional support therapy in patients with liver failure by summarizing the indicators for evaluating the nutritional and metabolic status and the features of nutrients and energy metabolism. We point out that resting energy expenditure can be measured using CCM-D nutrition metabolism test system in liver failure patients. Energy supply is primarily contributed by fat oxidation in patients with chronic liver failure, and their respiratory quotient is significantly lower than the predicted values. In addition, we discuss nutritional support intervention methods and intake for different stages of liver failure. Our aim is to raise the awareness of clinicians for malnutrition in patients with liver failure to formulate individualized nutrition support therapy.

Abstract
BACKGROUND The use of intravenous lipid emulsions in preterm infants has been limited by concerns regarding impaired lipid tolerance. As a result, the time of initiation of parenteral lipid infusion to very-low-birth-weight (VLBW) infants varies widely among different neonatal intensive care units. However, lipids provide energy for protein synthesis and supply essential fatty acids that are necessary for central nervous system development. OBJECTIVE The objective was to summarize the effects of initiation of lipids within the first 2 d of life and the effects of different lipid compositions on growth and morbidities in VLBW infants. DESIGN A systematic review and meta-analysis of publications identified in a search of PubMed, EMBASE, and Cochrane databases was undertaken. Randomized controlled studies were eligible if information on growth was available. RESULTS The search yielded 14 studies. No differences were observed in growth or morbidity with early lipid initiation. We found a weak favorable association of non-purely soybean-based emulsions with the incidence of sepsis (RR: 0.75; 95% CI: 0.56, 1.00). CONCLUSIONS The initiation of lipids within the first 2 d of life in VLBW infants appears to be safe and well tolerated; however, beneficial effects on growth could not be shown for this treatment nor for the type of lipid emulsion. Emulsions that are not purely soybean oil-based might be associated with a lower incidence of sepsis. Large-scale randomized controlled trials in preterm infants are warranted to determine whether early initiation of lipids and lipid emulsions that are not purely soybean oil-based results in improved long-term outcomes.

Abstract
BACKGROUND The aim of the present study was to determine the incidence and risk factors of parenteral nutrition-associated liver disease (PNALD) in neonates. METHODS A 1 year prospective cohort study was carried out at the neonatal intensive care unit and sick neonatal wards, Chiang Mai University Hospital. Newborns >1000 g, receiving >7 days of parenteral nutrition (PN), were enrolled. Liver function tests were done by the end of first, second, and fourth week, and then every 4 weeks until the PN was discontinued and the jaundice resolved. The diagnosis of PNALD relied on a history of PN, direct bilirubin >2 mg/dL, and exclusion of other causes of neonatal cholestasis. Selected patient factors and PN compositions were analyzed to determine the risks for development of PNALD. RESULTS A total of 24 infants with a mean gestational age and birthweight of 32.5 weeks and 1840 g were enrolled. Eight of the 24 developed PNALD. Compared to those without PNALD, gastrointestinal surgery, duration of enteral starvation, duration of PN, maximum PN caloric intake, and maximum carbohydrate intake were significantly associated with the development of liver disease. Despite the lack of statistical significance, there was a trend towards cholestasis in patients with sepsis. Elevation of direct bilirubin was the earliest biochemical change, observed in the first week after PN, followed by increased transaminases. CONCLUSION Gastrointestinal surgery, duration of enteral starvation, duration of PN, maximum caloric and carbohydrate intake in PN were significant risks of PNALD in newborn infants.

Abstract
BACKGROUND Newborn infants with short bowel syndrome (SBS) represent a high-risk group of developing intestinal failure-associated liver disease (IFALD), which may be fatal. However, infants have a great capacity for intestinal growth and adaptation if IFALD can be prevented or reversed. A major contributing factor to IFALD may be the soybean oil-based intravenous lipid emulsions used since the introduction of parenteral nutrition (PN) 40 years ago. METHODS This retrospective study compares the outcome in 20 neonates with SBS treated with parenteral fish oil (Omegaven) in combination with ω-6/9 lipid emulsions (ClinOleic) with the outcome in a historical cohort of 18 patients with SBS who received a soybean oil-based intravenous lipid emulsion (Intralipid). RESULTS Median gestational age was 26 weeks in the treatment group and 35.5 weeks in the historical group. All patients were started on PN containing Intralipid that was switched to ClinOleic/Omegaven in the treatment group at a median age of 39 gestational weeks. In the treatment group, direct bilirubin levels were reversed in all 14 survivors with cholestasis (direct bilirubin >50 umol/L). Median time to reversal was 2.9 months. Only 2 patients died of liver failure (10%). In the historical cohort, 6 patients (33%) died of liver failure, and only 2 patients showed normalization of bilirubin levels. CONCLUSIONS Parenteral fish oil in combination with ω-6/9 lipid emulsions was associated with improved outcome in premature neonates with SBS. When used instead of traditional soybean-based emulsions, this mixed lipid emulsion may facilitate intestinal adaptation by increasing the IFALD-free period.

Abstract
BACKGROUND/PURPOSE The optimal management of neonates with gastroschisis is unclear, and there is a significant morbidity. We performed a review of neonates with gastroschisis treated at our center of pediatric surgery over the last 21 years to determine predictive factors of outcome. METHODS Single-center retrospective analysis of 79 neonates with gastroschisis (1989-2009) was done. Length of hospital stay (LOS), days of parenteral nutrition (PN), and survival were outcome measures. Univariate and multiple regression analyses were used. RESULTS Overall survival was 92%, and primary closure was achieved in 80%. Median LOS was 25 days, and median duration on PN, 17 days. Intestinal atresia, closed gastroschisis, secondary closure, and sepsis were the primary variables associated with poor outcome independent of other variables, but prematurity also affected outcome. Route of delivery and associated malformations were not related to poorer outcome. Necrotizing enterocolitis did not occur in any of our patients. CONCLUSION Outcome in our patients was favorable as measured by survival, LOS, and days on PN. Primary predictors of poor outcome were factors related to short bowel syndrome and secondary closure, indicating a need to further improve treatment of short bowel syndrome.
