Abstract
BACKGROUND We quantify the osmolality of human milk fortified with human milk fortifiers (HMFs), powder infant formulas and protein additives. METHODS Commercial liquid HMFs and powder infant formulas were added to pasteurized pooled donor human milk in triplicate and stirred. The osmolality of unfortified and fortified human milk at 22, 24, 26, 27, 28, and 30 kcal/oz (0.73, 0.8, 0.87, 0.9, 0.93, and 1 kcal/ml, respectively) was determined using freezing-point depression. RESULTS The osmolality of fortified human milk associated with energy density in a linear relationship regardless of the fortification strategies. Multiple liquid HMFs and every powder infant formula exceeded the osmolality threshold of 450 mOsm/kg H2 O within the energy densities tested. CONCLUSION The osmolality of fortified human milk is highly variable and should be considered when selecting a fortifying agent for human milk.

Front Pediatr 2023; 11:1173133. [PMID: 37772037 PMCID: PMC10522910 DOI: 10.3389/fped.2023.1173133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 08/29/2023] [Indexed: 09/30/2023] Open
Abstract
Background Perturbation of osmolality is associated with increased mortality in adults and children in critically ill conditions. However, it is still unclear whether osmolality imbalance impacts the prognosis of critically ill infants. This study aimed to investigate the relationship between plasma osmolality and prognosis in critically ill infants within 24 h of admission. Methods This retrospective study enrolled 1,042 infants who had plasma osmolality data from 2010 to 2018. The initial plasma osmolality (within 24 h after admission) was extracted from the pediatric intensive care database (PIC V1.1). The locally weighted scatter-plot smoothing (LOWESS) and restricted cubic splines (RCS) methods were used to explore the approximate relationship between plasma osmolality and in-hospital mortality. Univariate and multivariate logistic regression analyses were used to further analyse this relationship. Kaplan-Meier analysis was applied to estimate the probability of hospital mortality within 90 days of admission. Subgroup analysis was employed to assess the impact of potential confounders (including postnatal days, gender, and gestational age). Results An approximately"U"-shaped relationship between plasma osmolality and mortality was detected. In the logistic regression model, plasma osmolality <270 mmol/L (low osmolality group) was significantly associated with in-hospital mortality (P < 0.05; OR 2.52; 95% CI, 1.15-5.06). Plasma osmolality >300 mmol/L (high osmolality group) was also significantly associated with mortality (P < 0.05; OR 3.52; 95% CI, 1.16-8.83). This association remained even after multivariable adjustments. The 90-day survival rate was lower in the abnormal plasma osmolality group (including high or low osmolality groups) than in the intermediate group (log-rank test, P < 0.05). The abnormal plasma osmolality group had a significantly higher incidence of all-cause mortality in the 0-7 postnatal days subgroup (high osmolality group, P < 0.05; OR 5.25; low osmolality group, P < 0.05; OR 3.01). Infants with abnormal osmolality had a significantly higher mortality rate in the female group (P < 0.05). High osmolality was associated with a higher mortality rate in the preterm group (P < 0.05). Conclusions Both hypoosmolality and hyperosmolality were shown to be independently associated with increased risk of in-hospital infant mortality in NICUs.

Abstract
Multicomponent fortification is the standard of care to support short-term growth in preterm infants receiving human milk. There is no consensus regarding the optimal timing, method, or products used to fortify human milk. Both bovine milk-based and human milk-based human milk fortifiers are safe options, though increased fortification and enrichment may be needed to achieve adequate growth. Additional studies are needed to evaluate newer fortifier products and fortification strategies.

Abstract
OBJECTIVES To review the current literature and develop consensus conclusions and recommendations on nutrient intakes and nutritional practice in preterm infants with birthweight <1800 g. METHODS The European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee of Nutrition (CoN) led a process that included CoN members and invited experts. Invited experts with specific expertise were chosen to represent as broad a geographical spread as possible. A list of topics was developed, and individual leads were assigned to topics along with other members, who reviewed the current literature. A single face-to-face meeting was held in February 2020. Provisional conclusions and recommendations were developed between 2020 and 2021, and these were voted on electronically by all members of the working group between 2021 and 2022. Where >90% consensus was not achieved, online discussion meetings were held, along with further voting until agreement was reached. RESULTS In general, there is a lack of strong evidence for most nutrients and topics. The summary paper is supported by additional supplementary digital content that provide a fuller explanation of the literature and relevant physiology: introduction and overview; human milk reference data; intakes of water, protein, energy, lipid, carbohydrate, electrolytes, minerals, trace elements, water soluble vitamins, and fat soluble vitamins; feeding mode including mineral enteral feeding, feed advancement, management of gastric residuals, gastric tube placement and bolus or continuous feeding; growth; breastmilk buccal colostrum, donor human milk, and risks of cytomegalovirus infection; hydrolyzed protein and osmolality; supplemental bionutrients; and use of breastmilk fortifier. CONCLUSIONS We provide updated ESPGHAN CoN consensus-based conclusions and recommendations on nutrient intakes and nutritional management for preterm infants.

Abstract
BACKGROUND Phenylalanine-free infant formula is an essential source of safe protein in a phenylalanine restricted diet, but its efficacy is rarely studied. We report a multicentre, open, longitudinal, prospective intervention study on a phenylalanine-free infant formula (PKU Start: Vitaflo International Ltd.). RESULTS This was a 2-part study: part I (28 days short term evaluation) and part II (12 months extension). Data was collected on infant blood phenylalanine concentrations, dietary intake, growth, and gastrointestinal tolerance. Ten infants (n = 8 males, 80%), with a median age of 14 weeks (range 4-36 weeks) were recruited from 3 treatment centres in the UK. Nine of ten infants completed the 28-day follow-up (one caregiver preferred the usual phenylalanine-free formula and discontinued the study formula after day 14) and 7/9 participated in study part II. The phenylalanine-free infant formula contributed a median of 57% (IQR 50-62%) energy and 53% (IQR 33-66%) of total protein intake from baseline to the end of the part II extension study. During the 12-month follow-up, infants maintained normal growth and satisfactory blood phenylalanine control. Any early gastrointestinal symptoms (constipation, colic, vomiting and poor feeding) improved with time. CONCLUSION The study formula was well tolerated, helped maintain good metabolic control, and normal growth in infants with PKU. The long-term efficacy of phenylalanine-free infant formula should continue to be observed and monitored.

Abstract
Ibuprofen is commonly used for the treatment of hemodynamically significant patent ductus arteriosus (PDA) in preterm infants. It seems that the oral formulation incurs a higher closure rate and has a better safety profile in preterm infants born > 26 weeks’ gestation. There is no consensus across Canadian centers regarding the minimum volume of enteral feeds required prior to starting ibuprofen for the treatment of patent ductus arteriosus, and the current practice is comfort-based depending on the centre and the local prevalence of neonatal morbidities.

Abstract
Formula feeding is an important risk factor for the development of necrotizing enterocolitis in preterm infants. The potential harmful effects of different preterm formulas on the developing intestinal tract remain incompletely understood. Here we demonstrate that feeding newborn mouse pups with various preterm formulas resulted in differing effects on intestinal inflammation, apoptosis, and activation of the pro-inflammatory transcription factor NFκB. 16S rRNA sequencing revealed that each preterm formula resulted in significant gut microbial alterations that were different from dam-fed controls. Formula feeding with EleCare and Similac Special Care caused greater intestinal injury compared to NeoSure. Pre-treatment with Lactobacillus rhamnosus GG ameliorated severity of intestinal injury from EleCare and Similac Special Care. Our findings indicate that not all preterm formulas are the same, and different formulations can have varying effects on intestinal inflammation, apoptosis, and microbiome composition.

Abstract
OBJECTIVE The devastation of pharmaceutical production facilities from Hurricane Maria caused a national shortage of parenteral amino acids in October 2017. Our institution decreased trophamine in very low birth weight (VLBW) infants and initiated human milk fortification at a lower feeding volume to increase enteral protein intake more quickly. The objective of this study was to assess how protein management during the shortage period affected the incidence of malnutrition. METHODS This was a retrospective cohort study of infants admitted to 2 neonatal intensive care units from June 1, 2017 to May 31, 2018. Infants between 23 and 32 weeks' gestation were included in this study. The primary outcome was the incidence of malnutrition at 14 days, defined as a z score decline of ≥0.8 SDs, in the pre-shortage period compared with the shortage period. Clinical data regarding adverse effects associated with early fortification and pharmacy costs were recorded. RESULTS There were 68 infants prior to and 65 during the shortage who met inclusion criteria. There was no difference in malnutrition between the pre-shortage and shortage groups; however, a significant increase in malnutrition was observed in infants who did not receive early fortification during the shortage. No difference in time to full enteral feeds or necrotizing enterocolitis was observed with early fortification. CONCLUSIONS Early fortification in VLBW infants receiving less trophamine during the shortage was not associated with an increase in malnutrition. Restricting trophamine in neonates during the shortage allowed for distribution to other critically ill patients.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is a multifactorial gastrointestinal disease which mostly occurs in very low birth weight (VLBW) infants. In addition to decreasing gestational age (GA) or birth weight (BW), artificial formula, delayed initiation or rapidly advanced feeding, severe anemia and systemic infections were associated with NEC. Several studies demonstrated that breast milk, standardized feeding advancement regimens and treatment of anemia are associated with less incidence of NEC. It is not known if including all these interventions in one multifaceted program will lead to significant reduction in NEC. METHODS The NICU team at The George Washington University Hospital created a multifaceted interdisciplinary quality improvement project to tackle several aspects of NEC prevention that addressed researched risk factors for NEC. The program was made of four quality improvement protocols: 1) Standardized Structured Feeding Program, 2) Feeding Intolerance Management Algorithm, 3) Enteral Osmolality Control Tool, and 4) Packed Red Blood Cell (RBC) Standardized Transfusion Protocol. This time-series, quasi experimental study design examined the differences in the incidence of NEC between infants with BW < 1500 g who were admitted to the GW Hospital NICU before and after the program implementation. RESULTS Data from 408 VLBW infants were included in the study. Although not statistically significant, there was a decreasing trend of NEC incidence in the post-implementation group (n = 199) compared to the pre-implementation group (n = 209), (3.5% vs. 5.3%, p = 0.88). The trend in the incidence of NEC declined further after the introduction of RBC transfusion protocol which was introduced ten month after starting the other elements of the program. CONCLUSION Integration of the multifaceted quality improvement program may be associated with a decline in the occurrence of NEC. Further analysis with a larger sample size is required to determine if the changes seen are statistically significant.

Abstract
There is a need to develop dosage forms suitable for children to improve drug treatment. Extemporaneous compounding of drugs for children is one way to meet these needs. However, excipients generally considered as safe in adults may not be appropriate in dosage forms intended for children. The aim was to optimize the composition of two pediatric liquid preparations by substituting paraben as a microbiological preservative and ethanol as a solubilizer, with excipients more suitable for pediatric use. The oral liquids were Naloxone 1 mg/mL and Propranolol 10 mg/mL. Twelve different formulations were tested with propranolol and naloxone, respectively, during the screening process to select appropriate formulations. Sodium benzoate and glycerol were used as a preservative and solubilizer, respectively, and different pH of the formulations were evaluated. The formulations were characterized according to dispensed dose (dosing accuracy), viscosity and osmolality. The optimized formulations from the screening process were tested with two amounts of sodium benzoate and microbiological assays were performed. These formulations were shown to have satisfactory preservative properties and dosing accuracy. The results showed that the oral liquids could be prepared without the addition of solubilizer and with lower osmolality (naloxone), thus reducing the risk of gastrointestinal side effects.

Abstract
INTRODUCTION Short bowel syndrome (SBS) results from significant intestinal loss and is characterized by insufficient absorption of nutrients and fluids. Preclinical large animal SBS models typically require parenteral nutrition (PN) support and may not be appropriate for studying interventions to improve intestinal absorption or adaptation. Here, we describe the development of a porcine SBS model that does not require PN support. METHODS Eight male Yorkshire piglets underwent either a 75% or 90% jejunoileal resection (n = 5) or no resection (n = 3). Continuous enteral nutrition (EN) was provided via a gastrostomy tube. The final SBS model consisted of a 75% resection and nutrition provided via combination EN (60%) and per oral pig chow (40%). Body weight and concentration of fat-soluble vitamins were assessed on postoperative days (POD) 7, 14, and 21. For assessing fat malabsorption, the coefficient of fat absorption (CFA) was calculated following a 72-h stool collection. RESULTS Resected animals had decreased weight gain compared to unresected controls (POD21 + 8.3% versus +28.8%, P = 0.048). Vitamin D concentration was significantly lower in resected animals compared to controls on POD 7, POD 14, and POD 21. Serum vitamin E concentration was also lower on POD 21. Resected animals developed fat malabsorption with lower CFA (76.5% versus 95.3%, P = 0.014). CONCLUSIONS We describe the development of a porcine SBS model that does not require PN support. Piglets in this model gain less weight, demonstrate fat malabsorption, and develop fat-soluble vitamin deficiencies. This model will benefit investigations of intestinal absorption or adaptation while potentially decreasing costs and confounding complications related to PN administration.

An Interdisciplinary Approach to Reducing NEC While Optimizing Growth: A 20-Year Journey. Adv Neonatal Care 2021; 21:433-442. [PMID: 34510070 DOI: 10.1097/anc.0000000000000929] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
BACKGROUND Necrotizing enterocolitis (NEC) and postnatal growth restriction are significant clinical dilemmas that contribute to short- and long-term morbidities for the most premature infants. PURPOSE After a rise in NEC rates in a regional neonatal intensive care unit (NICU), improvement practices were implemented by an interdisciplinary quality improvement (QI) work group whose focus was initially on nutrition and growth. QI work was refocused to address both NEC and growth concurrently. METHODS Through various QI initiatives and with evolving understanding of NEC and nutrition, the work group identified and implemented multiple practices changes over 2-decade time span. A standardized tool was used to review each case of NEC and outcomes were continually tracked to guide QI initiatives. LOCAL FINDINGS Focused QI work contributed to a significant reduction in NEC rates from 16.2% in 2007 to 0% in 2018 for inborn infants. Exclusive human milk diet was a critical part of the success. Postnatal growth outcomes initially declined after initial NEC improvement work. Improvement work that focused jointly on NEC and nutrition resulted in improved growth outcomes without impacting NEC. IMPLICATIONS FOR PRACTICE Use of historical perspective along with evolving scientific understanding can guide local improvement initiatives. Work must continue to optimize lactation during NICU hospitalization. More research is needed to determine impact of care practices on gastrointestinal inflammation including medication osmolality, probiotics, and noninvasive respiratory support.

Abstract
BACKGROUND The European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) position paper from 2015 on percutaneous endoscopic gastrostomy (PEG) required updating in the light of recent clinical knowledge and data published in medical journals since 2014. METHODS A systematic review of medical literature from 2014 to 2020 was carried out. Consensus on the content of the manuscript, including recommendations, was achieved by the authors through electronic and virtual means. The expert opinion of the authors is also expressed in the manuscript when there was a lack of good scientific evidence regarding PEGs in children in the literature. RESULTS The authors recommend that the indication for a PEG be individualized, and that the decision for PEG insertion is arrived at by a multidisciplinary team (MDT) having considered all appropriate circumstances. Well timed enteral nutrition is optimal to treat faltering growth to avoid complications of malnutrition and body composition. Timing, device choice and method of insertion is dependent on the local expertise and after due consideration with the MDT and family. Major complications such as inadvertent bowel perforation should be avoided by attention to good technique and by ensuring the appropriate experience of the operating team. Feeding can be initiated as early as 3 hours after tube placement in a stable child with iso-osmolar feeds of standard polymeric formula. Low-profile devices can be inserted initially using the single-stage procedure or after 2-3 months by replacing a standard PEG tube, in those requiring longer-term feeding. Having had a period of non-use and reliance upon oral intake for growth and weight gain-typically 8-12 weeks-a PEG may then safely be removed after due consultation. In the event of non-closure of the fistula the most successful method for closing it, to date, has been a surgical procedure, but the Over-The-Scope-Clip (OTSC) has recently been used with considerable success in this scenario. CONCLUSIONS A multidisciplinary approach is mandatory for the best possible treatment of children with PEGs. Morbidity and mortality are minimized through team decisions on indications for insertion, adequate planning and preparation before the procedure, subsequent monitoring of patients, timing of the change to low-profile devices, management of any complications, and optimal timing of removal of the PEG.

Abstract
Researchers have recently called for human lactation research to be conceptualized as a biological framework where maternal and infant factors impacting human milk, in terms of composition, volume and energy content are studied along with relationships to infant growth, development and health. This approach allows for the development of evidence-based interventions that are more likely to support breastfeeding and lactation in pursuit of global breastfeeding goals. Here we summarize the seminal findings of our research programme using a biological systems approach traversing breast anatomy, milk secretion, physiology of milk removal with respect to breastfeeding and expression, milk composition and infant intake, and infant gastric emptying, culminating in the exploration of relationships with infant growth, development of body composition, and health. This approach has allowed the translation of the findings with respect to education, and clinical practice. It also sets a foundation for improved study design for future investigations in human lactation.

Abstract
Necrotizing enterocolitis (NEC), which is characterized by severe intestinal inflammation and in advanced stages necrosis, is a gastrointestinal emergency in the neonate with high mortality and morbidity. Despite advancing medical care, effective prevention strategies remain sparse. Factors contributing to the complex pathogenesis of NEC include immaturity of the intestinal immune defense, barrier function, motility and local circulatory regulation and abnormal microbial colonization. Interestingly, enteral feeding is regarded as an important modifiable factor influencing NEC pathogenesis. Moreover, breast milk, which forms the currently most effective prevention strategy, contains many bioactive components that are known to support neonatal immune development and promote healthy gut colonization. This systematic review describes the effect of different enteral feeding interventions on the prevention of NEC incidence and severity and the effect on pathophysiological mechanisms of NEC, in both experimental NEC models and clinical NEC. Besides, pathophysiological mechanisms involved in human NEC development are briefly described to give context for the findings of altered pathophysiological mechanisms of NEC by enteral feeding interventions.

Corrected fortification approach improves the protein and energy content of preterm human milk compared with standard fixed-dose fortification. Arch Dis Child Fetal Neonatal Ed 2021; 106:232-237.

Abstract
OBJECTIVE To evaluate whether a pragmatic corrected fortification (CF) model achieves recommended target protein and calorie content of human milk (HM) for preterm infants when compared with standard fixed-dose fortification (SF). DESIGN In this prospective non-interventional study, we enrolled mothers of infants with birth weight ≤1500 g fed exclusive HM. Infants with chromosomal or intestinal disorders were excluded. A total of 405 HM samples from 29 mothers and 45 donor milk samples were analysed for macronutrient content using a real-time HM analyser. A stepwise CF model was derived based on published data on HM calorie and protein content corrected for lactation stage and milk type. We applied both models to the measured protein and calorie content for all HM samples and compared the proportion of samples achieving target nutrient requirement in each group. RESULTS Target protein and calorie content of feed was achieved in 68% of HM samples with CF, compared with 5% samples with SF model (p<0.0001). For mother's own milk, none of the samples met the target macronutrient range with SF fortification during later lactation periods (≥week 5). With SF, over 40% of infants had poor growth (decline in weight z-score ≥0.8 SD) by 8 weeks. The final feed osmolality was acceptable for all fortification steps of the CF model. CONCLUSION The proposed CF model significantly improved the final protein and calorie content of HM with acceptable osmolality. It provides a proactive option to improve nutrient intake in premature infants.

Abstract
Quantification of human milk (HM) fat is important for determining the energy intake of infants. The simplest and most rapid method is the creamatocrit method. However, the reliability of the creamatocrit has not been comprehensively investigated. The aims of this study were to test the inter- and-intra-rater reliability of: 1) HM sampling after hand- or-machine mixing methods and 2) HM fat measurement by the creamatocrit method. Inter-and-intra rater HM sampling after hand- or-machine mixing methods had high intraclass correlation coefficient (>0.91). Inter-rater reliability of measurement of HM with low fat (<2%) resulted in high variability (median coefficient of variations (CVs) > 15%). Intra- and inter-rater reliability of measurement of HM with higher fat (>3.5%) had low variability (median CVs < 10%). As the greatest variation in the creamatocrit method occurred during the measurement of HM samples with low fat, duplicate readings are necessary to reduce discrepancies in every HM fat determination.

Abstract
OBJECTIVE The purpose of this study was to determine whether a point-of-care osmotic device concentrates important human milk (HM) nutrients to support feeding neonates requiring high-nutrient, low-volume feedings. STUDY DESIGN Raw and pasteurized HM samples were concentrated to determine the effects of time and temperature on concentration. Concentrated samples were compared with matched baseline samples to measure changes in selected nutrient concentrations. Furthermore, changes in concentration of certain bioactive components of raw milk samples were measured. RESULT The device significantly increased the concentrations of the majority of the measured nutrient and bioactive levels (p < 0.05). Increasing temperature of HM from 4 to 37 °C increased the concentration rate >30%. In all cases, the concentration rate of pasteurized HM was greater than that of raw HM. CONCLUSIONS The osmotic concentration of HM is a promising option for neonatal nutrition. Further studies are needed to establish an evidence base for the practical applications of this point-of-care device.

Abstract
OBJECTIVE The administration of hyperosmolar oral products in neonates has been associated with gastrointestinal complications. The American Academy of Pediatrics recommends a maximum osmolality of 450 mOsm/kg for formulas and enteral nutrition for term infants, and recent studies reported intolerance to enteral nutrition with osmolality above 500 mOsm/kg in low birthweight infants. The osmolality of medications administered to neonates is often not available in the literature or from manufacturers. The purpose of this study was to determine the osmolality of oral medications commonly administered to neonates in the NICU. METHODS Fifty-two oral medications were chosen for this study, including solutions, suspensions, syrups, elixirs, and intravenous solutions administered orally. The osmolality of each medication was measured in triplicate by using freezing point depression. RESULTS Thirty-seven of the 43 medications with measurable values (86.1%) had an osmolality greater than 500 mOsm/kg, and 6 medications (14%) had an osmolality less than 500 mOsm/kg. Nine medications did not result in a value. CONCLUSIONS Our study provides osmolality data on oral medications commonly used in neonates with most oral medications having an osmolality greater than 500 mOsm/kg.

Abstract
BACKGROUND Mother's own milk does not provide enough nutrients to feed a preterm baby born before 32 weeks' gestation; therefore, human milk fortifiers are needed. However, human milk fortifiers increase the osmolality, and enteral administration of high osmolality fluids has been associated with gastrointestinal symptoms. For this reason, it is necessary for laboratories to have a validated system in order to measure human milk osmolality. RESEARCH AIM The aim of this study was to validate the OM-6050 Station System for measuring the osmolality of fortified mother's milk samples. METHODS Osmolality was measured using the osmometer OM-6050 Station System. Milk samples from healthy mothers (N = 3) unfortified and with two fortifiers (Almirón Fortifier® or NAN FM85®), as well as a nutritional supplement (Duocal MCT®) were used in the validation study through precision and linearity analysis. RESULTS In the precision study the mean intra-assay coefficient of variation was 1.2% and 1.7% for mother's milk and fortified mother's milk, respectively. The mean inter-assay coefficient of variation was ≤ 1% in both cases. In the linearity study the regression analysis had a linear response to fortified mother's milk osmolality between 294 mOsm/kg and 539 mOsm/kg. CONCLUSION The osmometer OM-6050 Station was reliable for determining the osmolality of fortified and unfortified mother's milk. It may be useful in the clinical practices within Neonatal Intensive Care Units.

Abstract
Necrotizing enterocolitis (NEC), the first cause of short bowel syndrome (SBS) in the neonate, is a serious neonatal gastrointestinal disease with an incidence of up to 11% in preterm newborns less than 1500 g of birth weight. The rate of severe NEC requiring surgery remains high, and it is estimated between 20–50%. Newborns who develop SBS need prolonged parenteral nutrition (PN), experience nutrient deficiency, failure to thrive and are at risk of neurodevelopmental impairment. Prevention of NEC is therefore mandatory to avoid SBS and its associated morbidities. In this regard, nutritional practices seem to play a key role in early life. Individualized medical and surgical therapies, as well as intestinal rehabilitation programs, are fundamental in the achievement of enteral autonomy in infants with acquired SBS. In this descriptive review, we describe the most recent evidence on nutritional practices to prevent NEC, the available tools to early detect it, the surgical management to limit bowel resection and the best nutrition to sustain growth and intestinal function.

Abstract
INTRODUCTION Necrotizing enterocolitis (NEC) is a disease predominantly affecting preterm infants. The administration of hyperosmolar solutions could lead to the development of NEC. The objective of this study was to measure the osmolality of enteral medications used in clinical practice and to assess the risk of NEC following exposure to hyperosmolar medications. METHODS A retrospective cohort study in extremely preterm infants (gestational age <28 weeks) born between 2010 and 2016 at a tertiary neonatal intensive care unit in Sweden. 465 infants were identified via the Swedish Neonatal Quality register. Data relating to enteral administrations received during a two-week period were collected from the medical records. The osmolalities of medications were measured using an osmometer. Logistic regression was used to calculate the odds ratio of developing NEC. RESULTS A total of 253 patients met the inclusion criteria. The osmolalities of 5 commonly used medications significantly exceeded the recommended limit of 450 mOsm/kg set by the American Academy of Paediatrics (AAP). Most patients (94%) received at least one hyperosmolar medication. No significant risk of developing NEC could be found. CONCLUSION The medications used in clinical practice can significantly exceed the limit set by the AAP. This study does not indicate an increased risk of developing NEC in extremely preterm infants following exposure to hyperosmolar medications. Further studies in larger cohorts are needed to determine the specific cut-off level of osmolality in relation to the pathogenesis of NEC.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants. Survivors may suffer both short- and long-term morbidities. Current evidence suggests that the incidence of NEC can be reduced by standardizing the care delivery in addressing key risk factors including an altered gut microbiome, use of formula milk, hyperosmolar feeds, and unrestricted use of high-risk medications METHODS: Since 2014, the department has a workgroup who analyzed all cases of NEC within a month of diagnosis to identify preventable risk factors. Existing evidence-based quality improvement strategies were revised and new ones were implemented sequentially over the next 4 years. These strategies include (1) a standardized feeding protocol, (2) early initiation of enteral feeding using human milk, (3) optimization of the osmolality of preterm milk feeds using standardized dilution guidelines for additives, and (4) promotion of healthy microbiome by use of probiotics, early oral care with colostrum and by restricting high-risk medications and prolonged use of empirical antibiotics RESULTS: Baseline characteristics of the patients including sex, gestational age, and birth weight were similar during the study period. After implementing the evidence-based practices successively over 4 years, the incidence of NEC in very- low birth-weight (VLBW) infants dropped from 7% in 2014 to 0% (P < .001) in 2018. The duration of parenteral nutrition, use of central line, and days to full feeds were also reduced significantly (P < .05) CONCLUSION: Adopting evidence-based best practices resulted in a significant decrease in the incidence of NEC and improved the nutrition outcomes in VLBW infants.

Abstract
Preterm and sick term infants are commonly fed with expressed breast milk (EBM) that has been subjected to various storage and handling conditions before feeding that may cause lipase-mediated elevation of free fatty acids (FFA). This study was designed to describe the variation, between mothers' and within the same mother over time, in the concentration of FFA in EBM used in an Australian neonatal unit. A total of 256 EBM samples, 149 freshly expressed in the unit cot-side and 87 expressed at home and brought in to the unit, were collected from 32 mothers with an infant admitted to the neonatal intensive and/or special care units at the Women's and Children's Hospital, Adelaide. Among the fresh EBM samples collected cot-side, the average total fat content was 29.78 ± 9.28 mg/mL, and the FFA concentration was 1.70% of total fats (interquartile range [IQR]: 1.17-2.37%). Among the 10 mothers who provided fresh EBM at different stages of lactation, the concentration of FFA remained low overall, with some day-to-day variation (min 0.58% and max 5.0% of total fats within the same mother). The average total fat content of home collected EBM was similar to the cot-side collected samples, at 27.37 ± 8.23 mg/mL, and the FFA concentration was slightly higher at 2.49% of total fats (IQR: 1.74-3.29%). Overall, the FFA concentration of breast milk in the neonatal unit before and even after a short period of cold storage and handling is universally low.

Abstract
Inadequate nutrition supply in the early stage after birth is a risk factor for the development of bronchopulmonary dysplasia (BPD) in preterm infants, and it is also closely associated with the progression and clinical outcome of BPD. Optimized nutritional support is of great importance to reduce the incidence and severity of BPD and promote lung development and neurological prognosis. Based on the relevant studies in China and overseas, the expert consensus on BPD nutrition management is developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method. The consensus includes the following seven aspects: the importance of nutrition in BPD, fluid intake, energy intake, enteral nutrition, parenteral nutrition, post-discharge nutrition, and nutrition monitoring and evaluation.

Abstract
BACKGROUND Human breast milk (BM) fortification is required to feed preterm newborns with less than 32 weeks of gestation. However, addition of fortifiers increases osmolarity and osmolarity values higher than 450 mOsm/kg may be related to gastrointestinal pathology. Hence, fortifier selection and dosage are key to achieve optimal feeding. OBJECTIVES To compare the effect on osmolality of adding different fortifications, including recently developed formulations, to BM and to study evolution of osmolarity over time in supplemented BM. METHODS Frozen mature BM from 10 healthy mothers of premature newborns was fortified with each of the following human milk fortifiers (HMF): AlmirónFortifier®, NANFM85®, or PreNANFM85®. In addition, fortified BMs were modified with one of the following nutritional supplements (NS): Duocal MCT®, Nutricia® AminoAcids Mix, or Maxijul®. Osmolality of BM alone, fortified and/or supplemented was measured at 1 and 22 hours after their preparation. All samples were kept at 4°C throughout the study. RESULTS Osmolality of BM alone was close to 300 mOsm/kg and did not change over 22 hours. When equicaloric amounts of HMF AlmirónFortifier®, NANFM85®, and PreNANFM85® were added to BM, osmolality increased roughly to 480 mOsm/kg with the first two fortifiers and only to 433±6 mOsm/kg with the third one. Upon addition of any of four different NSs to BM modified with AlmirónFortifier® and NANFM85®, osmolality reached values greater than 520 mOsm/kg, while osmolality of PreNANFM85® with two out of the four NSs remained below 490 mOsm/kg. NSs supplementing carbohydrates and hydrolysed proteins resulted into a higher increase of BM osmolarity. Osmolality increased significantly with time and, after 22h, only BM modified with PreNANFM85® remained below 450 mOsm/kg. CONCLUSIONS Upon addition of the HMFs tested, BM osmolality increases significantly and keeps raising over time. All HMFs but the recently developed PreNAN FM85® at 4% exceed the AAP recommended threshold for osmolarity of 450 mOsm/kg. Addition of NSs to PreNAN FM85® at 4% significantly increases osmolality above 450 mOsm/Kg. Thus, using PreNAN FM85® at 5% may be preferable to adding nutritional supplements since nutritional recommendations by the ESPGHAN are reached with a lower increase in osmolality.

Abstract
Diuretics are commonly administered to infants with bronchopulmonary dysplasia (BPD) to improve respiratory function despite the absence of prospective data demonstrating long term benefits. While many potentially adverse effects of furosemide are known to clinicians, its direct and indirect impact on multiple pathophysiological processes need to be understood. While furosemide likely has a role in the management of infants with BPD, clinicians are encouraged to recognize these potential complications associated with furosemide administration. Specifically, a deeper understanding of the impact of diuretics on sodium metabolism neurohumoral regulation of cardiopulmonary physiology is required.

Abstract
OBJECTIVES The fortification of human milk can result in increased osmolality, which may be associated with adverse effects for preterm infants. To evaluate the effect of target fortification on the osmolality and microbiological safety of donor human milk and raw mature milk during the first 72 hours of storage. METHODS We performed target fortification of 63 pasteurized donor human milk (PDHM) and 54 raw mature milk (RMM) samples in a laminar flow hood. Osmolality (mOsm/kg) was evaluated before fortification (T0), immediately after fortification (T1), at 6 (T2), 24 (T3), 48 (T4), and 72 hours (T5) after fortification. Microbiological analysis was performed at T0, T4, and T5. During the study, all samples were stored at 4°C. RESULTS Mean osmolality at each study point for PDHM and RMM were, respectively: T0: 291.4 ± 11.0 versus 288.4 ± 5.6 (P = 0.06); T1: 384.8 ± 16.7 versus 398.3 ± 23.7; T2: 393.9 ± 17.7 versus 410.1 ± 27.0; T3: 397.8 ± 17.6 versus 417.9 ± 26.1; T4: 400.0 ± 16.5 versus 420.2 ± 24.9; T5: 399.6 ± 16.5 versus 425.2 ± 25.8 (P < 0.001 from T1 to T5). Microbiological analyses were negative at each study points for PDHM. At T0 16.1% of RMM samples had positive cultures, whereas the bacterial count remained stable thought the study. CONCLUSIONS PDHM's osmolality increases during the first 6 hours after fortification and remains stable and safe until 72 hours. RMM's osmolality increases during the first 24 hours and remains stable and safe until 72 hours. The storage at 4°C and the manipulation of PDHM and RMM samples in a laminar flow hood seem to be safe and preserve the microbiological safety of fortified pasteurized human milk until 72 hours.

Abstract
BACKGROUND Artificial formula can be manipulated to contain higher amounts of macro-nutrients than maternal breast milk but breast milk confers important immuno-nutritional advantages for preterm or low birth weight (LBW) infants. OBJECTIVES To determine the effect of feeding preterm or LBW infants with formula compared with maternal breast milk on growth and developmental outcomes. SEARCH METHODS We used the standard strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2018, Issue 9), and Ovid MEDLINE, Ovid Embase, Ovid Maternity & Infant Care Database, and CINAHL to October 2018. We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that compared feeding preterm or low birth weight infants with formula versus maternal breast milk. DATA COLLECTION AND ANALYSIS Two review authors planned independently to assess trial eligibility and risk of bias, and extract data. We planned to analyse treatment effects as described in the individual trials and report risk ratios and risk differences for dichotomous data, and mean differences for continuous data, with 95% confidence intervals. We planned to use a fixed-effect model in meta-analyses and to explore potential causes of heterogeneity in subgroup analyses. We planned to use the GRADE approach to assess the certainty of evidence. MAIN RESULTS We did not identify any eligible trials. AUTHORS' CONCLUSIONS There are no trials of formula versus maternal breast milk for feeding preterm or low birth weight infants. Such trials are unlikely to be conducted because of the difficulty of allocating an alternative form of nutrition to an infant whose mother wishes to feed with her own breast milk. Maternal breast milk remains the default choice of enteral nutrition because observational studies, and meta-analyses of trials comparing feeding with formula versus donor breast milk, suggest that feeding with breast milk has major immuno-nutritional advantages for preterm or low birth weight infants.

Abstract
The development of age-appropriate formulations should focus on dosage forms that can deliver variable yet accurate doses that are safe and acceptable to the child, are matched to his/her development and ability, and avoid medication errors. However, in the past decade, the medication needs of neonates have largely been neglected. The aim of this review is to expand on what differentiates the needs of preterm and term neonates from those of the older paediatric subsets, in terms of environment of care, ability to measure and administer the dose (from the perspective of the patient and carer, the routes of administration, the device and the product), neonatal biopharmaceutics and regulatory challenges. This review offers insight into those challenges posed by the formulation of medicinal products for neonatal patients in order to support the development of clinically relevant products.
