Abstract
Breastfeeding not only reduces infection-related morbidity, but also increases growth of preterm infants. Advantages of breast milk (BM) for preterm infants are significant. They continue to be studied. However, because not all preterm infants can receive breastfeeding, bovine-based infant formula (IF) is used as an alternative, which may increase the risk of several preterm complications. Exosomes isolated from biofluids are emerging as biomarkers in research of various diseases. Here, we characterized miRNA contents of exosomes in urine and serum samples of preterm infants who were BM and IF fed and performed transcriptomic analysis of small RNA libraries. We identified significantly up-regulated 6 miRNAs and 10 miRNAs, respectively. Gene Ontology (GO) analysis revealed that target genes of these miRNAs might participate in neuronal development, immunity modulation, detoxification of reactive oxygen species, and transmembrane exchange. Our data suggest that exosome-based systemic screening for preterm infants with breastfeeding might be a screening tool for identifying target molecules involved in therapy for preterm infants in neonatal intensive care unit (NICU) and for future application as nutraceutical formulations or pharmaceuticals.

Regulation of skeletal muscle protein synthesis in the preterm pig by intermittent leucine pulses during continuous parenteral feeding. JPEN J Parenter Enteral Nutr 2023; 47:276-286. [PMID: 36128996 PMCID: PMC10621874 DOI: 10.1002/jpen.2450] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/31/2022] [Accepted: 09/15/2022] [Indexed: 11/10/2022]
Abstract
BACKGROUND Extrauterine growth restriction is a common complication of preterm birth. Leucine (Leu) is an agonist for the mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) signaling pathway that regulates translation initiation and protein synthesis in skeletal muscle. Previously, we showed that intermittent intravenous pulses of Leu to neonatal pigs born at term receiving continuous enteral nutrition increases muscle protein synthesis and lean mass accretion. Our objective was to determine the impact of intermittent intravenous pulses of Leu on muscle protein anabolism in preterm neonatal pigs administered continuous parenteral nutrition. METHODS Following preterm delivery (on day 105 of 115 gestation), pigs were fitted with umbilical artery and jugular vein catheters and provided continuous parenteral nutrition. Four days after birth, pigs were assigned to receive intermittent Leu (1600 µmol kg-1 h-1 ; n = 8) or alanine (1600 µmol kg-1 h-1 ; n = 8) parenteral pulses every 4 h for 28 h. Anabolic signaling and fractional protein synthesis were determined in skeletal muscle. RESULTS Leu concentration in the longissimus dorsi and gastrocnemius muscles increased in the leucine (LEU) group compared with the alanine (ALA) group (P < 0.0001). Despite the Leu-induced disruption of the Sestrin2·GATOR2 complex, which inhibits mTORC1 activation, in these muscles (P < 0.01), the abundance of mTOR·RagA and mTOR·RagC was not different. Accordingly, mTORC1-dependent activation of 4EBP1, S6K1, eIF4E·eIF4G, and protein synthesis were not different in any muscle between the LEU and ALA groups. CONCLUSION Intermittent pulses of Leu do not enhance muscle protein anabolism in preterm pigs supplied continuous parenteral nutrition.

Abstract
Objective To investigate the effects of early combined training on the physical development of preterm infants of different gestational ages. Methods A total of 144 preterm infants from our hospital's neonatal intensive care unit (NICU) between 2019 and 2020 were selected as the research participants and randomly divided into an intervention group (77 cases) and a control group (67 cases). The physical development and catch-up growth satisfaction rate of preterm infants in the intervention and control groups were compared at 40 weeks, 3 months, 6 months and 12 months of corrected age. Results At 40 weeks of gestational age and corrected 3 months of gestational age, the physical growth indexes of the intervention group were higher than those of the control group, with a statistical difference (P < 0.05). At the corrected age of 12 months, the body weight and length of preterm infants in the <29 weeks intervention group were still higher than those in the control group (P < 0.05). The body weight of preterm infants in the 29-32 weeks and 32-34 weeks intervention groups was higher than in the control group (P < 0.05). There was no statistical difference between the intervention and control groups in the 34-37 weeks category (P > 0.05). The catch-up growth satisfaction rates of all the physical growth indexes in the intervention group were higher than those of the control group at the corrected 3 months for all the gestational ages (P < 0.05). While those indexes in the three >29 weeks intervention groups were higher than those in the <29 weeks intervention group at the corrected age of 12 months (P < 0.05). Conclusion Early combined training can promote the early catch-up growth of preterm infants, especially in the early gestational age groups (<34 weeks), and the catch-up growth promotion can last for 12 months. The older the gestational age, the sooner catch-up growth satisfaction will occur.

Abstract
BACKGROUND AND OBJECTIVES Postnatal growth failure happens in about half of the very low birth weight infants and this can have long-term consequences. Human milk-based multi-nutrient fortifiers (HMBF) are thought to be better tolerated than bovine milk-based multi-nutrient fortifiers (BMBF), thus facilitating early progression to full feeds and improved growth in preterm neonates. This study was done to find the advantage of HMBF over BMBF on postnatal growth and other clinical outcomes. METHODS This is a retrospective cohort study where babies <1500 g birth weight or gestational age <32 weeks were included to compare the velocity of weight gain (g/kg/day), duration of hospital stay and clinical outcomes between fortification using HMBF and BMBF till 34 weeks postmenstrual age. RESULTS Eligible neonates included in the study were 322, out of whom 123 (37%) received HMBF and 209 (63%) received BMBF. During the stay, 18 babies were changed from BMBF to HMBF and vice versa in 24 babies due to logistic reasons and parents' preferences. The mean birth weight of the babies was 1124 ± 237 g. Weight gain was higher in the exclusive HMBF group [mean difference 0.77 (0.14, 1.39) g/kg/day; p-value = 0.018]. Feed intolerance [odds ratio (OR) 0.45 (0.22, 0.95), p-value 0.037] was also significantly less in this group. However, other morbidities did not differ significantly between the groups. CONCLUSION Higher weight gain and lower feed intolerance in the HMBF group underscores the possible advantage of using HMBF over BMBF. Larger prospective studies might bring out its effect on the duration of hospital stay and other morbidities.

Abstract
BACKGROUND The oral nutrition is big challenge for preterm neonates. Since the best oral feeding method for preterm neonates is not yet known, the present study aimed to evaluate the effect of cup, syringe, and finger feeding methods on reaching the time of full oral feeding and weight gain among preterm neonates. METHOD This randomized clinical trial study was conducted on 99 preterm neonate's, born at 30-34 weeks gestation, admitted to the neonatal intensive care unit (NICU) of Al-Zahra and Taleghani Therapeutic-Educational Centers in Tabriz, Iran. Subjects were assigned into finger feeding (n = 33), cup feeding (n = 33), and syringe feeding (n = 33) groups in the allocation ratio of 1:1:1 using block randomization with a block size 6 and 9. They were studied in terms of reaching the time of full oral feeding and weight gain. The data were analyzed using SPSS/version21 software, and ANOVA, chi-square, and ANCOVA tests. RESULTS There was no significant difference in the mean score of reaching the time of full oral feeding among cup, finger, and syringe feeding groups (p = 0.652). The mean score of daily weight gain, oxygen saturation (SaO2), and heart rate after feeding was not significantly different among the three groups (p > 0.05). The effect of confounding variables, including birth weight and age, arterial oxygen saturation, and heart rate before feeding, was controlled. CONCLUSION Based on the results, one of the cup, finger, and syringe feeding methods can be applied in the NICU, considering the staff's proficiency in feeding neonates. Trial registration IRCT20150424021917N11.

Abstract
There is limited information regarding the use of parenteral nutrition (PN) in term and late preterm infants. We conducted a survey to study the current clinical practices within Australia and New Zealand (ANZ). A fifteen-question online survey was distributed to 232 neonatologists and fifty-five paediatric intensivists across ANZ between September and November 2019. At least one neonatologist from twenty-seven out of thirty tertiary neonatal intensive care units responded (90 %). Responses were received from sixty-nine neonatologists (30 %) and seven paediatric intensivists (13 %). The overall response rate was 26 % (76/287). Thirty-three percent (25/76) commenced PN within 24 h of admission, 27 % (20/75) between 24 and 48 h, 24 % (18/75) between 48 and 72 h, 9 % (7/75) between 72 and 96 h and 4 % (3/75) between 96 h and 7 days. None of the respondents commenced PN after 7 d of admission. Sixty-one percent (46/75) aimed for 1·5-3 g/kg per d of parenteral amino acids, whereas 27 % (20/75) aimed for 2-3 g/kg per d. Renal failure (59 %; 38/64) and high plasma urea (44 %; 28/64) were the major indications for withholding/decreasing the amino acid intake. Eighty-three percent (63/76) aimed for a dose of 2·5g-3·5 g/kg per d of parenteral lipids; about 9 % (7/76) targeted a dose of 1-2·5 g/kg per d and 4 % (3/76) for > 3·5 g/kg per d. Thirty-two percent (24/74) reported that they would withhold/decrease the dose of parenteral lipids in infants with sepsis. The variations in clinicians' practices with respect to the use of PN in term and late preterm infants highlight the need for high-quality research in this population.

Abstract
In human milk banks (HMBs), donor milk (DM) is commonly sterilized by Holder pasteurization (HoP). High hydrostatic pressure (HHP) processing is an innovative, alternative method for DM sterilization. We evaluated the impact of HHP processing on the concentration of seven metabolic milk hormones. Eight samples of raw DM were aliquoted. One aliquot was sterilized by HoP (62 °C for 30 min), and another was processed by HHP (350 MPa at 38 °C). Compared with raw DM, HoP milk displayed reduced concentrations of insulin, nesfatin-1, cortisol, leptin, apelin and GLP-1, though adiponectin levels were unchanged. HHP processing maintained the levels of insulin, nesfatin-1, cortisol and leptin at their initial levels in raw DM, reduced apelin and adiponectin levels, but increased GLP-1 level. Sterilization of DM by HHP thus preserves the main metabolic hormones in human milk, underlining the interest of this method for use in HMBs.

Abstract
OBJECTIVE Enteral feeding after intestinal atresia has always been a concern for clinicians. But the present studies mainly focused on single factors. This research aimed to comprehensively analyze the multiple factors on complete enteral nutrition after primary anastomosis, and establish the convenient prediction model. METHODS We retrospectively collected reliable information in neonates with intestinal atresia form January 2010 to June 2022. The cox regression analysis was performed to select independent risk factors and develop nomogram. Subsequently, ROC curve, calibration curve and decision curve were drawn to thoroughly evaluate the accuracy and applicability of the model. RESULTS The predictors finally included in the model were gestational age, meconium peritonitis, distance from the anastomosis to the ileocecal region, diameter ratio of proximal to distal bowels, and time of initial feeding. The nomogram of predicting the probability of week 2, week 3 and week 4 was drawn and their area under the curve were 0.765, 0.785 and 0.747, respectively. Similarly, calibration and decision curve indicated that the prediction model had a great prediction performance. CONCLUSION The clinical value of predictive models can be recognized. The hope is that the predictive model can help pediatricians reduce hospital costs and parental anxiety.

Abstract
OBJECTIVE This study aims to explore the difficulties related to fresh colostrum feeding for very (extremely) low birth weight infants (VLBWI/ELBWI) and optimize the colostrum administration process. METHODS The VLBWI/ELBWI who were admitted in the neonatal intensive care unit from January to December 2021, were enrolled as the experimental group, and an optimized colostrum feeding process was adopted. The VLBWI/ELBWI admitted from January to December 2020 were enrolled as the control group, and a conventional feeding process was adopted. The general situation of colostrum supply, number of adverse feeding events, maternal breastfeeding rate at the critical time points. RESULTS There were no significant differences between the baseline charatcteristics of the 2 groups. In the experimental group, compared with the control group, the time to first colostrum collection was significantly shorter (64.8% vs. 57.8% p < 0.05), and the rates of colostrum feeding (44.1% vs. 70.5% p < 0.001), and of maternal breastfeeding at 2 weeks after birth (56.1% vs. 46.7%, p < 0.05) and on the day of discharge (46.2% vs. 37.8%, p < 0.05) were significantly higher. Before and after process optimization, the average total time required for the time for nurses to receive the colostrum in the NICU reduced from 7.5 min/time to 2 min/time, and no feeding-related adverse events occurred. CONCLUSION Fresh colostrum feeding process optimization for VLBWI/ELBWI, improves the colostrum feeding rate, shortens the time to first colostrum collection, saves the working time of nurses, and improves the maternal breastfeeding rate at key time points.

Abstract
BACKGROUND Clinical experience in managing extremely low gestational age infants, particularly those born <24 weeks' gestation, is limited in Canada. Our goal was to develop a bedside care bundle for infants born <26 weeks' gestation, with special considerations for infants of <24 weeks, to harmonize and improve quality of care. METHODS We created a multidisciplinary working group with experience in caring for preterm infants, searched the literature from 2000 to 2019 to identify best practices for the care of extremely preterm infants and consulted colleagues across Canada and internationally. Iterative improvements were made following the Plan-Do-Study-Act methodology. RESULTS A care bundle, created in October 2015, was divided into three time periods: initial resuscitation/stabilization, the first 72 hours and days 4 to 7, with each period subdivided in 8 to 12 care themes. Revisions and practice changes were implemented to improve skin integrity, admission temperature, timing of initiation of feeds, reliability of transcutaneous CO2 monitoring and ventilation. Of 127 infants <26 weeks admitted between implementation and end of 2019, 78 survived to discharge (61%). CONCLUSION It will be important to determine, with ongoing auditing and further evaluation, whether our care bundle led to improvements of short- and long-term outcomes in this population. Our experience may be useful to others caring for extremely low gestational age infants.

PURPOSE OF REVIEW To review the current evidence evaluating early versus delayed commencement of parenteral nutrition in infants. RECENT FINDINGS Recent studies in very premature infants (<32 weeks gestation) have shown that early commencement of parenteral nutrition immediately after birth improves physical growth. However, there are concerns that early use of very high dose of amino-acids (>3.5 g/kg/day immediately after birth) may cause metabolic acidosis, elevated blood urea, slower head growth and refeeding-hypophosphatemia syndrome. A recent multicentre randomized controlled trial found that commencement of parenteral nutrition within 24-h of admission increases the risk of infections and prolongs the duration of ventilation and ICU stay in full-term neonates, older infants and children. The study also found that delaying to day 8 of admission increased the risk of hypoglycaemia. SUMMARY Benefits of commencing parenteral nutrition on the first day of life appear to outweigh risks in very premature infants; however, it is prudent to avoid early very high doses of amino acids (>3.5 g/kg/day) in the first few days of life. In moderate to late preterm infants, if enteral feeds are not tolerated by 72 h, it is reasonable to commence parenteral nutrition. In full-term and older infants, it is preferable to avoid parenteral nutrition within 24 h of admission and consider delaying by further few days. Diligent monitoring of blood glucose, serum phosphate and other parameters is essential while on parenteral nutrition.

Abstract
Background: Intravenous lipid emulsions (IL) are an important part of parenteral nutrition (PN) to meet essential fatty acid (EFA) requirements and metabolic demands of neonates and preterm infants. Some critically-ill neonates may not metabolize IL effectively which can lead to hypertriglyceridemia. Risks associated with this include increased pulmonary vascular resistance, displaced bilirubins, and platelet or macrophage dysfunction. Serum triglyceride (TG) concentration is used as a marker for lipid tolerance and predictor of potential complications involved with IL administration, but the clinical significance of this is still debated. Management of TG levels with regard to timing of laboratory tests, the ideal goal range, and duration of infusion of IL varies across institutions and is not standardized. Methods: Single-center, retrospective study of newborn infants receiving parenteral nutrition (PN). Fasting and non-fasting TG levels were drawn during the same lipid infusion of 2-3g/kg/day. The primary outcome was the difference between fasting and non-fasting TG levels. Statistical assessment of continuous data was done with student t-test and nominal data was evaluated using X2-test and logistic regression. Results: Forty infants were included with mean gestational age at birth of 29.5 ± 3.4 weeks and mean birth weight of 1.3 ± 0.5 kg. Mean time between lab draws while on same IL dose was 11.6 ± 0.2 h with resulting mean fasting and non-fasting (random) TG levels 82 ± 40 mg/dL (95% CI 68.4, 97.6) and 101 ± 40 mg/dL (95% CI 88.5, 115.8), respectively. Mean difference between TG levels during lipid-free interval and during infusion was -18.6 ± 51.2 mg/dL (95% CI -35.0, -2.3; p = 0.03). Conclusion: We concluded there is no difference in the management of IL, when TG level was drawn randomly or as fasting sample. Obtaining TG level during routine lab draws is appropriate. We extrapolated that the administration of IL over 24 h will not interfere with TG level.

Abstract
The number of infants born preterm including extremely premature babies is rising worldwide, particularly in low- and middle-income countries, which challenge neonatologists and milk banks for the provision of the most adequate nutrition for successful infant's growth and development. The benefits of mother's own milk (MOM) have been extensively recognized, but the use of donor milk (DM) is a commonly routine practice in preterm neonates admitted to the NICU. Pasteurized mature milk from milk banks is not the same composition than the mother's colostrum and premature milk, the characteristics of which protect the infant from the risk for necrotizing enterocolitis, late-onset sepsis, and other comorbidities associated with prematurity. The development of a personalized nutrition unit (PNU) allows to obtain DM from mothers who have their infants admitted to the NICU and produce an excess of milk, a practice that matches MOM by gestational age and the stage of lactation, ensuring an adequate composition of DM to target the nutritional requirements of premature infants.Conclusion: This narrative review presents salient data of our current knowledge and concerns regarding milk feeding of preterm infants in the NICU, with special emphasis on personalized DM as a result of establishing a PNU. What is Known: • Donor milk bank is mature or pooled milk from lactating mothers at different stages of lactation. • Milk composition varies by gestational age and stage of lactation. What is New: • Donor milk from mothers delivered prematurely have the most adequate composition for preterm infant feeding. • Personalized nutrition for premature infants with preterm donor milk is feasible.

Abstract
BACKGROUND Umbilical venous catheters (UVC) and peripherally inserted central catheters (PICC) are commonly used in preterms. UVC is cheap, easy to insert but has shorter dwell time. UVC is replaced after 7 days due to the risk of complications. This is associated with increased cost, work, and risk of nosocomial infections. The aim of this study was to determine the antenatal and postnatal factors that predict the need for a central line for more than 7 days, thus helping select between UVC or PICC on day 1 of life in babies ≤1500 grams. METHODS We retrospectively collected antenatal and postnatal data of VLBW neonates over a period of 1 year who needed CL during their NICU stay. We then divided them into two cohorts. Group 1: CL ≤7 days. Group 2: CL > 7 days. RESULTS Sepsis and catheter complications were lower with use of a single CL or duration being ≤7 days. Birth weight, incomplete/no antenatal steroids, need for resuscitation, low Apgar's, RDS, hs-PDA, and initiation of feeds beyond 24 hours of birth were significant. The score was devised based on factors found significant that had an acceptable AUC of 0.767 on ROC analysis with a score of 1 or above having 74.8% sensitivity and 67.7% specificity for prediction of need for CL > 7 days. CONCLUSIONS Birth weight ≤1000 grams, incomplete steroids and need for resuscitation at birth were predictive of the need of CL beyond seven days, on day one of life.

Abstract
AIM To understand the use of breast milk and breastfeeding in preterm infants in neonatal intensive care units (NICUs) in mainland China. METHODS An online questionnaire survey of reported practices was conducted among 18 tertiary NICUs distributed across all seven districts in mainland China. The items of the questionnaire consisted of the following areas: breastfeeding rate of preterm infants (<37 weeks' gestation) at discharge, the standards used for guiding the clinical practice and the use of breast milk and breastfeeding. RESULTS On average, across all hospitals, breastfeeding rate for preterm infants at discharge was 65%, with 41% preterm infants being exclusively breastfed during the hospitalisation prior to discharge. Sixteen (89%) NICUs had policies designating breast milk as the preferred first feed for preterm infants. Donor milk was available in 3 of 18 (17%) NICUs. Kangaroo care was provided in 11 of 18 (61%) NICUs, and 14 of 18 (78%) allowed parental access to the hospitalised preterm infants. A large variation was found in clinical practices around the breast milk testing, breast milk storage and transportation and breast milk fortification methods among different NICUs. CONCLUSIONS The use of breast milk in hospitalised preterm infants has increased greatly but still needs to be further improved. A recommendation is made to conduct high-quality original trials to find evidence of the controversial problems, develop evidence-based guidelines, promote the best implementation of the guidelines and provide updated breastfeeding education to health-care providers in order to standardise the use of breast milk and breastfeeding in hospitalised preterm infants.

Abstract
BACKGROUND Preterm infants who are fed breast milk in comparison to infant formula have decreased morbidity such as necrotizing enterocolitis. Multi-nutrient fortifiers used to increase the nutritional content of the breast milk are commonly derived from bovine milk. Human milk-derived multi-nutrient fortifier is now available, but it is not clear if it improves outcomes in preterm infants fed with breast milk. OBJECTIVES To determine whether the fortification of breast milk feeds with human milk-derived fortifier in preterm infants reduces mortality, morbidity, and promotes growth and development compared to bovine milk-derived fortifier. SEARCH METHODS We searched the following databases for relevant trials in September 2018. Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, Issue 9), electronic journal reference databases including MEDLINE (1980 to 20 September 2018), PREMEDLINE, Embase (1974 to 20 September 2018), CINAHL (1982 to 20 September 2018), biological abstracts in the database BIOSIS and conference abstracts from 'Proceedings First' (from 1992 to 2011). We also included the following clinical trials registries for ongoing or recently completed trials: ClinicalTrials.gov (ClinicalTrials.gov), the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP; www.whoint/ictrp/search/en/) and the ISRCTN Registry (www.isrctn.com/), and abstracts of conferences: proceedings of Pediatric Academic Societies (American Pediatric Society, Society for Pediatric Research and European Society for Paediatric Research) from 1990 in the 'Pediatric Research' journal and 'Abstracts online' (2000 to 2017). SELECTION CRITERIA We included randomized and quasi-randomized controlled trials that compared preterm infants fed breast milk fortified with human milk-derived fortifier versus those fed with breast milk fortified with bovine milk-derived fortifier. DATA COLLECTION AND ANALYSIS The data were collected using the standard methods of Cochrane Neonatal. Two authors evaluated trial quality of the studies and extracted data. We reported dichotomous data using risk ratios (RRs), risk differences (RDs), number needed to treat (NNT) where applicable, and continuous data using mean differences (MDs). We assessed the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS One randomized trial with 127 infants met the eligibility criteria and had low risk of bias. Human milk-based fortifier did not decrease the risk of necrotizing enterocolitis in exclusively breast milk-fed preterm infants (RR 0.95, 95% CI 0.2 to 4.54; 1 study, 125 infants, low certainty of evidence). Human milk-derived fortifiers did not improve growth, decrease feeding intolerance, late-onset sepsis, or death. AUTHORS' CONCLUSIONS There is insufficient evidence evaluating human milk-derived fortifier with bovine milk-derived fortifier in exclusively breast milk-fed preterm infants. Low-certainty evidence from one study suggests that in exclusively breast milk-fed preterm infants human milk-derived fortifiers in comparison with bovine milk-derived fortifier may not change the risk of necrotizing enterocolitis, mortality, feeding intolerance, infection, or improve growth. Well-designed randomized controlled trials are needed to evaluate short-term and long-term outcomes.

Abstract
BACKGROUND An exclusive human milk-based diet has been shown to decrease necrotizing enterocolitis and improve outcomes for infants ≤1250 g birth weight. Studies have shown that infants who received an exclusive human milk diet with a donor-human milk-derived cream supplement (cream) had improved weight and length velocity when the cream was added to mother's own milk or donor-human milk when energy was <20 kcal/oz using a human milk analyzer. Our objective was to compare growth and cost outcomes of infants ≤1250 g birth weight fed with an exclusive human milk diet, with and without human milk cream, without the use of a human milk analyzer. METHODS Two cohorts of human milk-fed premature infants were compared from birth to 34 weeks postmenstrual age. Group 1 (2010-2011) received a donor-human milk fortifier, whereas Group 2 (2015-2016) received donor-human milk fortifier plus the commercial cream supplement, if weight gain was <15 g/kg/d. RESULTS There was no difference in growth between the 2 groups for weight (P = 0.32) or head circumference (P = 0.90). Length velocity was greater for Group 1 (P = 0.03). The mean dose of donor-human milk fortifier was lower in Group 2 (P < 0.001). Group 2 saved an average of $2318 per patient on the cost of human milk products (P < 0.01). CONCLUSIONS Infants receiving a human milk diet with cream supplementation for growth faltering achieve appropriate growth in a cost-effective feeding strategy.

Abstract
Background: Bronchopulmonary dysplasia (BPD) is the most common complication of very preterm birth and can lead to lifelong health consequences. Optimal nutrition is a cornerstone in the prevention and treatment of BPD. In very preterm infants, mother's own milk (MOM) feeding is associated with lower risks of necrotizing enterocolitis, retinopathy of prematurity, and sepsis. Although several studies have shown that MOM may protect against BPD, a systematic analysis of the evidence has not been performed to date. Methods: A comprehensive literature search was conducted using PubMed/MEDLINE and EMBASE, from their inception to 1 December 2017. Longitudinal studies comparing the incidence of BPD in preterm infants fed with exclusive MOM, MOM supplemented with preterm formula (PF), and/or exclusively fed with PF were selected. A random-effects model was used to calculate the Mantel Haenszel risk ratio (RR) and 95% confidence interval (CI). Results: Fifteen studies met the inclusion criteria (4,984 infants, 1,416 BPD cases). Use of exclusive MOM feedings was associated with a significant reduction in the risk of BPD (RR 0.74, 95% CI 0.57-0.96, 5 studies). In contrast, meta-analysis could not demonstrate a significant effect on BPD risk when infants fed with more than 50% MOM were compared with infants fed with <50% MOM (RR 0.98, 95% CI 0.77-1.23, 10 studies) or when infants fed with MOM supplemented with PF were compared with infants fed with exclusive PF (RR 1.00, 95% CI 0.78-1.27, 6 studies). Meta-regression showed that differences in gestational age were a significant confounder of the effect of MOM. Conclusion: To our knowledge, this is the first systematic review and meta-analysis that specifically evaluates the role of MOM on BPD. Our data indicate that MOM may reduce the incidence of BPD when used as an exclusive diet, but this result needs to be interpreted with caution. We did not find the same difference in analyses with other dosages of MOM. Further studies adequately powered to detect changes in BPD rates and that adjust for confounders are needed to confirm the beneficial effects of MOM on BPD.

Abstract
OBJECTIVES Preterm neonates have an immature gastrointestinal tract and show an altered bacterial colonization of the gut. However, it is not clear if such immature gut microbiota (GM) colonization is induced by specific delivery, diet, environment, and/or host factors related to preterm birth. Using piglets as models for infants, we hypothesized that both shortened gestational age (GA) and start of enteral feeding affect GM composition after caesarean delivery and rearing in identical environments. METHODS Caesarean-delivered preterm and term pigs were reared in incubators and fed total parenteral nutrition (TPN) or gradually increasing early enteral feeding (EEF) for 5 days, followed by full enteral feeding with bovine milk until day 26. GM composition was determined by 16S rRNA gene-amplicon sequencing and luminal short-chain fatty acids (SCFAs) by GC-MS. RESULTS Both GA and EEF feeding affected GM composition on day 5, but only the GA effect persisted until day 26. On day 5, Enterobacteriaceae were dominant, with Lachnospiraceae members also being abundant. Enterobacteriaceae still dominated the GM at day 26 but with higher Akkermansia relative abundance in term pigs. Colonic concentrations of acetate and propionate were higher, and formate lower in term pigs, relative to preterm pigs on day 26. CONCLUSIONS Preterm and term piglets, born and reared in similar ways, show differences in GM colonization during the first 4 weeks of life, which may play a role for early and later gut dysfunction resulting from preterm birth.

Abstract
BACKGROUND The objective of our study was to examine whether outpatient respiratory morbidities in infants with bronchopulmonary dysplasia (BPD) are influenced by the human milk consumption. METHODS Caregivers of subjects recruited from a BPD clinic completed questionnaires regarding breast milk intake and respiratory outcomes. RESULTS One-hundred eighty-eight caregivers completed the questionnaire. Of these, 173 (92.0%) reported that the child received some breast milk. Infants who received breast milk for fewer months were more likely to be non-white, and have a lower household income, public insurance, and secondhand smoke exposure. A longer receipt of breast milk was associated with reduced likelihoods of emergency department visits, systemic steroid courses, and cough or chest congestion, and a trend towards a lower risk of re-hospitalizations. CONCLUSIONS Longer duration of breast milk intake was associated with markers of higher socio-economic status, and reduced likelihood of acute and chronic respiratory morbidities among preterm infants with bronchopulmonary dysplasia.

Abstract
Breast milk is considered the gold standard nutritional resource for very low birth weight (VLBW) infants in terms of nutrients and protective factors. If mother's milk is not available, the second choice is donated and fortified human milk (HM) from the Human Milk Bank (HMB). This study hypothesized that HM could be lyophilized and used as an additive to increase the levels of macronutrients and micronutrients available to VLBW infants. This study aimed to constitute a lyophilized HM concentrate and determine the osmolality and the concentration of macronutrients and micronutrients in HM samples at “baseline” and in “HM concentrates”, analyzed immediately (HMCI), and after 3 (HMC3m) and 6 (HMC6m) months of freezing. Osmolality was verified using the freezing point osmometric method. Macronutrient quantification was performed using the MIRIS Human Milk Analyzer. Micronutrients were determined by Flame Atomic Absorption Spectrophotometry and by the automated colorimetric method. Bayesian linear mixed effect models were adjusted using OpenBUGS to estimate mean differences and 95% credibility intervals (CrI) of osmolality and of macro- and micronutrients between the types of HM samples. A comparison of dosage values showed a significant increase between HM baseline and HMCI, HMC3m, and HMC6m. Comparing HM baseline and HMCI highlighted the increase in energy content and the concentration of carbohydrates and total lipids. The Ca and P contents increased and the levels of energy, total lipids, and Cu were reduced in HMC3m compared to HMCI. Ca, Mg, K, Zn, and P increased and the levels of energy, total lipids, and Cu were reduced in HMC6m, compared to HMCI. The present study confirms the possibility of formulation and utilization of the immediate concentrate. Partial stability of HM concentrates generated from freeze-drying of donated milk do not recommend storage.

Abstract
OBJECTIVE We examined the effect of two strategies to prevent necrotizing enterocolitis (NEC) in extremely low birth weight (ELBW) infants-adherence to a standardized feeding protocol and use of a hospital-based milk bank to provide exclusive preterm human milk feedings. STUDY DESIGN We conducted a single-center observational study from 2010 to 2015. Infants received preterm human milk, initially trophic feeds from days 7 to 14 after birth, followed by advancement of 15 mL/kg/day to reach a goal of 180 mL/kg/day. Fortification was used selectively for weight gain < 15 g/kg/day. We determined the incidence of NEC, other morbidities, and growth. RESULTS The cohort included 398 ELBW infants who survived to day 14 without congenital anomalies. Mean gestational age was 26.2 ± 1.9 weeks. Maternal milk was used as the sole feeding in 62% of infants; preterm donor milk was used solely or as supplement in 29%. Full feeds were reached at a median of 27 (IQR 23, 33) days. Four infants (1%) developed NEC. CONCLUSION Use of standardized feedings with a hospital-based milk bank is associated with an incidence of NEC lower than previously reported.

Choline and choline-related nutrients in regular and preterm infant growth. Eur J Nutr 2018; 58:931-945.

Abstract
BACKGROUND Choline is an essential nutrient, with increased requirements during development. It forms the headgroup of phosphatidylcholine and sphingomyelin in all membranes and many secretions. Phosphatidylcholine is linked to cell signaling as a phosphocholine donor to synthesize sphingomyelin from ceramide, a trigger of apoptosis, and is the major carrier of arachidonic and docosahexaenoic acid in plasma. Acetylcholine is important for neurodevelopment and the placental storage form for fetal choline supply. Betaine, a choline metabolite, functions as osmolyte and methyl donor. Their concentrations are all tightly regulated in tissues. CLINCAL IMPACT During the fetal growth spurt at 24-34-week postmenstrual age, plasma choline is higher than beyond 34 weeks, and threefold higher than in pregnant women [45 (36-60) µmol/L vs. 14 (10-17) µmol/L]. The rapid decrease in plasma choline after premature birth suggests an untimely reduction in choline supply, as cellular uptake is proportional to plasma concentration. Supply via breast milk, with phosphocholine and α-glycerophosphocholine as its major choline components, does not prevent such postnatal decrease. Moreover, high amounts of liver PC are secreted via bile, causing rapid hepatic choline turnover via the enterohepatic cycle, and deficiency in case of pancreatic phospholipase A2 deficiency or intestinal resection. Choline deficiency causes hepatic damage and choline accretion at the expense of the lungs and other tissues. CONCLUSION Choline deficiency may contribute to the impaired lean body mass growth and pulmonary and neurocognitive development of preterm infants despite adequate macronutrient supply and weight gain. In this context, a reconsideration of current recommendations for choline supply to preterm infants is required.

Abstract
BACKGROUND Human milk, with essential nutrients and long chain polyunsaturated fatty acids (LC-PUFAs) such as the omega 3 and 6 fatty acids is important for development of the central nervous system and the retina in very low birth weight infants (<1,500 g). However, breast milk may not be sufficient to meet these needs. The possibility of supplementing breast milk with a lyophilisate of human milk was explored in this study. The objectives of this study were to determine the total lipid content and the lipid profile of the Human Milk on Baseline (HMB) and that of the Concentrates with the Human Milk + lyophilisate (with lyophilisate of milk in the immediate period (HMCI), at 3 months (HMC3m), and at 6 months (HMC6m) of storage). METHODS Fifty donors from the Human Milk Bank of Children's Hospital provided consent, and donated milk samples. Macronutrient (including total lipids) quantification was performed using the MIRIS® Human Milk Analyzer, and the fatty acid profile was determined by gas chromatography (CG-FID, SHIMADZU®). RESULTS There was a higher lipid concentration in HMCI relative to HMB. The concentrations of the main fatty acids (% of total) were as follows: palmitic acid (C16:0) HMB, 22.30%; HMCI, 21.46%; HMC3m, 21.54%; and HMC6m, 21.95% (p<0.01); oleic acid (C18:1n-9) HMB, 30.41%; HMCI, 30.47%; HMC3m, 30.55%; and HMC6m, 29.79% (p = 0.46); linoleic acid (C18:2n-6) HMB, 19.62%; HMCI, 19.88%; HMC3m, 19.49%; and HMC6m, 19.45% (p = 0.58); arachidonic acid (C20:4n-6) HMB, 0.35%; HMCI, 0.16%; HMC3m, 0.13%; and HMC6m, 0.15% (p<0.01); α-linolenic acid (C18:3n-3) HMB,1.32%; HMCI, 1.37%; HMC3m, 1.34%; and 1.34% HMC6m (p = 0.14); docosahexaenoic acid (C22:6n-3) HMB, 0.10%; HMCI, 0.06%; HMC3m, 0.05%; and HMC6m, 0.06% (p<0.01). There were no significant changes in the lipid profile when stored. There was no evidence of peroxidation during storage. CONCLUSIONS Freeze-dried human milk fortified with a human milk concentrate brings potential benefits to newborns, mainly by preserving the essential nutrients present only in breast milk; however, further clinical studies are required to evaluate the safety and efficacy of the concentrate as a standard nutritional food option for very low birth weight infants.

Abstract
BACKGROUND Extremely preterm birth is associated with a high risk of extrauterine growth retardation, which has been linked with adverse developmental outcomes. OBJECTIVE We investigated whether nutritional management during the first 7 days of life affects growth patterns until the corrected age of 2 years in extremely preterm infants. STUDY DESIGN A retrospective study of 78 extremely preterm (<28 weeks' gestation) neonates was conducted. Data regarding parenteral and enteral intake of energy, protein, lipids, and carbohydrates during the first 7 days of life were collected from patient records. The outcome measures included weight, height, and head circumference with Z scores at term-equivalent age and the corrected ages of 1 and 2 years. Analyses were performed with hierarchical-linear mixed models. RESULTS Nutritional intake during the first week of life did not reach the current recommendations. The total energy intake during the first 7 days of life was statistically significantly associated with weight, length, and head circumference until the corrected age of 2 years after adjusting for potential confounding factors. Individual macronutrient intake displayed no association with growth patterns. CONCLUSIONS Energy intake during the first 7 days of life is associated with growth until the corrected age of 2 years. These results provide support for the aggressive early nutritional management of extremely preterm infants.

Abstract
The goals of early nutrition in preterm infants are to provide all the necessary vital nutrients, achieve extra-uterine growth rates similar to fetuses of the same gestational age, and support functional neurodevelopmental outcomes that are comparable to those of infants born at term. It is vital to provide nutrition that will maximally support brain growth and development, but over-feeding with accelerated growth, fat accumulation and long-term metabolic consequences should also be avoided. Because the morbidity associated with prematurity increases nutritional and energetic demands, the basic approach is of providing early intensive nutrition. Protein is the main driving force for growth and brain development. Since deficits in protein occur from the first day of extra-uterine life, sufficient quantities of parenteral amino acids should be provided from the first hours of life. With protein and carbohydrates, enough energy should also be provided, via concomitant early administration of intravenous lipid emulsions. Early initiation of enteral feeding with advancement to full enteral nutrition is associated with better maturation of the gut and better neuro-developmental outcomes. Human milk is the best food for preterm babies, although enrichment may be needed.
