Abstract
Research on human milk has increased dramatically in recent years. The purpose of this review is to describe the literature on the health benefits of human milk for hospitalized, vulnerable neonates. PubMed, CINAHL, and Embase were searched for research articles reporting the health outcomes of hospitalized neonates who were exposed to human milk. Human milk, particularly a mother's own milk, has the potential to reduce the risk of death and the risk and severity of necrotizing enterocolitis, infection, retinopathy of prematurity, bronchopulmonary dysplasia, intraventricular hemorrhage, kidney disease, and liver disease. Dose and timing of human milk is important, with more human milk and earlier introduction having a greater impact on health. When a mother's own milk is not available, donor human milk provides benefits over infant formula.

Abstract
IMPORTANCE The effect of using an exclusive human milk diet compared with one that uses bovine products in preterm infants is uncertain, but some studies demonstrate lower rates of key neonatal morbidities. A potential mediating pathway is the gut microbiome. OBJECTIVE To determine the effect of an exclusive human milk diet on gut bacterial richness, diversity, and proportions of specific taxa in preterm infants from enrollment to 34 weeks' postmenstrual age. DESIGN, SETTING, AND PARTICIPANTS In this randomized clinical trial conducted at 4 neonatal intensive care units in the United Kingdom from 2017 to 2020, microbiome analyses were blind to group. Infants less than 30 weeks' gestation who had only received own mother's milk were recruited before 72 hours of age. Statistical analysis was performed from July 2019 to September 2021. INTERVENTIONS Exclusive human milk diet using pasteurized human milk for any shortfall in mother's own milk supply and human milk-derived fortifiers (intervention) compared with bovine formula and bovine-derived fortifier (control) until 34 weeks' postmenstrual age. Fortifier commenced less than 48 hours of tolerating 150 mL/kg per day. MAIN OUTCOMES AND MEASURES Gut microbiome profile including alpha and beta diversity, and presence of specific bacterial taxa. RESULTS Of 126 preterm infants enrolled in the study, 63 were randomized to control (median [IQR] gestation: 27.0 weeks [26.0-28.1 weeks]; median [IQR] birthweight: 910 g [704-1054 g]; 32 [51%] male) and 63 were randomized to intervention (median [IQR] gestation: 27.1 weeks [25.7-28.1 weeks]; median [IQR] birthweight: 930 g [733-1095 g]; 38 [60%] male); 472 stool samples from 116 infants were analyzed. There were no differences in bacterial richness or Shannon diversity over time, or at 34 weeks between trial groups. The exclusive human milk diet group had reduced relative abundance of Lactobacillus after adjustment for confounders (coefficient estimate, 0.056; P = .03), but not after false discovery rate adjustment. There were no differences in time to full feeds, necrotizing enterocolitis, or other key neonatal morbidities. CONCLUSIONS AND RELEVANCE In this randomized clinical trial in preterm infants using human milk-derived formula and/or fortifier to enable an exclusive human milk diet, there were no effects on overall measures of gut bacterial diversity but there were effects on specific bacterial taxa previously associated with human milk receipt. These findings suggest that the clinical impact of human milk-derived products is not modulated via microbiomic mechanisms. TRIAL REGISTRATION ISRCTN trial registry identifier: ISRCTN16799022.

Abstract
INTRODUCTION Mother's own breast milk (MOM) is the optimal nutrition for preterm infants as it reduces the incidence of key neonatal morbidities and improves long-term outcomes. However, MOM shortfall is common and either preterm formula or pasteurised donor human milk (DHM) may be used, although practice varies widely. Limited data suggest that the use of DHM may impact maternal beliefs and behaviours and therefore breastfeeding rates. The aim of this pilot study is to determine if longer duration of DHM exposure increases breastfeeding rates, and if a randomised controlled trial (RCT) design is feasible. METHODS AND ANALYSIS The Human Milk, Nutrition, Growth, and Breastfeeding Rates at Discharge (HUMMINGBIRD) Study is a feasibility and pilot, non-blinded RCT with a contemporaneous qualitative evaluation. Babies born less than 33 weeks' gestation or with birth weight <1500 g whose mothers intend to provide MOM are randomly assigned to either control (DHM used to make up shortfall until full feeds and preterm formula thereafter) or intervention (DHM used for shortfall until 36 weeks' corrected age or discharge if sooner). The primary outcome is breast feeding at discharge. Secondary outcomes include growth, neonatal morbidities, length of stay, breastfeeding self-efficacy and postnatal depression using validated questionnaires. Qualitative interviews using a topic guide will explore perceptions around use of DHM and analysed using thematic analysis. ETHICS APPROVAL AND DISSEMINATION Nottingham 2 Research Ethics Committee granted approval (IRAS Project ID 281071) and recruitment commenced on 7 June 2021. Results will be disseminated in peer-reviewed journals. TRIAL REGISTRATION NUMBER ISRCTN57339063.

Antenatal and Postnatal Sequelae of Oxidative Stress in Preterm Infants: A Narrative Review Targeting Pathophysiological Mechanisms. Antioxidants (Basel) 2023; 12:antiox12020422. [PMID: 36829980 PMCID: PMC9952227 DOI: 10.3390/antiox12020422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 02/01/2023] [Accepted: 02/07/2023] [Indexed: 02/11/2023] Open
Abstract
The detrimental effects of oxidative stress (OS) can start as early as after conception. A growing body of evidence has shown the pivotal role of OS in the development of several pathological conditions during the neonatal period, which have been therefore defined as OS-related neonatal diseases. Due to the physiological immaturity of their antioxidant defenses and to the enhanced antenatal and postnatal exposure to free radicals, preterm infants are particularly susceptible to oxidative damage, and several pathophysiological cascades involved in the development of prematurity-related complications are tightly related to OS. This narrative review aims to provide a detailed overview of the OS-related pathophysiological mechanisms that contribute to the main OS-related diseases during pregnancy and in the early postnatal period in the preterm population. Particularly, focus has been placed on pregnancy disorders typically associated with iatrogenic or spontaneous preterm birth, such as intrauterine growth restriction, pre-eclampsia, gestational diabetes, chorioamnionitis, and on specific postnatal complications for which the role of OS has been largely ascertained (e.g., respiratory distress, bronchopulmonary dysplasia, retinopathy of prematurity, periventricular leukomalacia, necrotizing enterocolitis, neonatal sepsis). Knowledge of the underlying pathophysiological mechanisms may increase awareness on potential strategies aimed at preventing the development of these conditions or at reducing the ensuing clinical burden.

Abstract
Objective To evaluate the impact of a standardized feeding protocol and donor breast milk (DBM) provision on clinical outcomes in moderate preterm infants (MPT, 29-33 6/7 weeks gestational age). Study Design A protocol for MPT infants born > 1500 g was implemented clinically to standardize feeding advancements at 30 mL/kg/day. Infants < 33 weeks received DBM. We retrospectively identified 131 and 144 infants born before and after implementation. Clinical data including central venous line (CVL) placement, feeding tolerance, growth, and provision of maternal breast milk (MBM) were collected. Result Number of CVLs, days to full enteral volume (FEV), and MBM provision was unchanged. There was a narrower range of days to FEV post-implementation. Growth metrics were similar between eras. Conclusion Implementation of a feeding protocol for MPT infants is associated with more consistent time to FEV With monitoring and appropriate fortification, DBM use in this population is not associated with worse growth outcomes.

Preventing severe necrotizing enterocolitis: Propensity score analysis of interventions associated with surgical NEC or NEC-associated death. J Pediatr Surg 2023; 58:828-833. [PMID: 36805136 DOI: 10.1016/j.jpedsurg.2023.01.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 01/03/2023] [Indexed: 01/19/2023]
Abstract
PURPOSE To determine what modifiable interventions used in the neonatal intensive care unit (NICU) are associated with severe necrotizing enterocolitis (NEC) requiring surgical intervention. METHODS A retrospective review of patients treated for NEC at a tertiary hospital from 1991 to 2016 was performed. Patient characteristics were used to calculate propensity scores for likelihood of exposure to seven interventions: enteral feeds, use of glucocorticoids, nonsteroidal anti-inflammatory drugs (NSAIDs), antacids, antibiotics, or umbilical arterial (UAC) and venous catheters (UVC). Conditional logistic regression was used to compare the odds of having surgical NEC if exposed to each treatment. RESULTS We included 195 NEC patients: 69 severe NEC managed with surgery and 126 non-severe NEC managed medically. After propensity score matching based on birth characteristics, exposure to glucocorticoids (OR 5.21, 95%CI: 1.62, 16.70), NSAIDs (OR 4.87, 95%CI: 1.67, 14.17), UVC (OR 2.53 (95%CI: 1.19, 5.73), and UAC (OR 4.91, 95%CI: 2.12, 11.37) were associated with surgical NEC in separate conditional logistic regression analyses. Including these treatments in a second round of propensity matching and conditional logistic regression revealed that glucocorticoids (OR 2.99, 95%CI: 1.01, 8.88), NSAIDs (OR 3.97, 95%CI: 1.41, 11.19), UVC (OR 3.07, 95%CI: 1.46, 6.48), and UAC (OR 5.10, 95%CI: 2.10, 12.36) were still associated with surgical NEC. CONCLUSION After controlling for birth confounders and common NICU supportive interventions, use of glucocorticoids, NSAIDs and umbilical catheters independently increased the odds of developing severe NEC requiring surgical intervention. LEVEL-OF-EVIDENCE RATING Case-control, Level III evidence.

Abstract
This study investigated whether delayed receipt of antibiotics in infants with necrotizing enterocolitis (NEC) is associated with disease severity. In this retrospective, single-center cohort study of infants diagnosed with NEC over 4 years, we compared the timing of antibiotic administration in infants (time order placed to time of receipt) in medical and surgical NEC. Cases were independently reviewed, then various clinical factors were compared. Of 46 suspected cases, 25 were confirmed by a panel of radiologists with good interrater reliability (ICC 0.657; p < 0.001). Delays in antibiotic receipt were 1.7× greater in surgical than medical NEC cases (p = 0.049). Every hour after order entry increased the adjusted odds of surgical NEC by 2.4 (1.08−5.23; p = 0.032). Delayed antibiotic receipt was more common in infants with surgical than medical NEC. Larger studies will be needed to investigate if optimizing antibiotic expediency could improve intestinal outcomes.

Abstract
OBJECTIVE To compare pH of human milk types (mother's own milk (MOM), pasteurized donor human milk (PDHM), fortified MOM, and fortified PDHM) fed to preterm infants. STUDY DESIGN This observational study consisted of 63 mother-infant dyads < 34 weeks gestation. Human milk samples (n = 245), along with maternal factors, were collected for pH analysis. pH of MOM was analyzed over the course of lactation accounting for fortification status, postpartum day, and storage conditions. RESULTS Mean pH of MOM was slightly acidic at 6.60 ± 0.28, which was significantly higher (p < 0.05) than other milk types. pH of MOM varied by fortification, postpartum day, and maternal vegetable/fiber intake. There was a significant interaction between fortification status and postpartum day; pH of MOM decreased over time, while pH of fortified MOM increased over time. CONCLUSION pH of human milk varied by type. pH of MOM was significantly associated with fortification status, postpartum day, and maternal vegetable/fiber intake.

Abstract
OBJECTIVE Prompted by an acute increase in necrotizing enterocolitis (NEC) rates, we aimed to decrease the rate of stage 2 or greater NEC in infants born at <1500 grams or <30 weeks gestational age from 19.5% to less than 9.7% (a 50% reduction) within 18 months, without adversely affecting central line-associated bloodstream infection (CLABSI) rates. STUDY DESIGN We utilized Define, Measure, Analyze, Improve, and Control (DMAIC) as our improvement model. Informed by our key driver diagram and root cause analyses, six Plan-Do-Study-Act cycles were completed. RESULTS 147 infants in the QI initiative had a median gestational age of 28.1 weeks and a median birthweight of 1070 grams. NEC rates decreased from the QI baseline of 19.5% to 6% (p = 0.03). Oral care administration increased, and maximal gavage tube dwell time decreased. CONCLUSION NEC rates decreased during this QI initiative through a combination of multidisciplinary interventions aimed at reducing dysbiosis.

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

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.

BACKGROUND Growing evidence supports the superior benefits of exposure to mother's own milk (MOM) in reducing prematurity-related comorbidities. Neonatal exposure to donor human Milk (DHM) is a suitable alternative when MOM is insufficient or unavailable. However, the same protective composition and bioactivity in MOM are not present in DHM. Additional evidence is needed to justify and inform evidence-based practices increasing MOM provision while optimizing adequate use of DHM for premature infants. PURPOSE A systematic review of the literature was conducted to determine differences in neonatal outcomes among premature infants exposed to predominately MOM versus DHM. METHODS/SEARCH STRATEGY Databases including PubMed, CINAHL and Cochrane were searched (2020-2021) using the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) guidelines. Evidence was classified using the John Hopkins evidence-based practice levels and quality of evidence. RESULTS Eleven studies met inclusion criteria. Studied neonatal outcomes included ( a ) growth parameters (n = 8), ( b ) neonatal morbidities (n = 6), and ( c ) gut microbiome (n = 4). Overall, evidence suggests DHM exposure is beneficial but not equivalent to MOM feeding. Compared with DHM, greater doses of MOM are ideal to enhance protection primarily related to infant growth, as well as gut microbiome diversity and richness. IMPLICATIONS FOR PRACTICE Standardized and evidence-based practices are needed to clearly delineate optimal use of DHM without undermining maternal and neonatal staff efforts to support and promote provision of MOM. IMPLICATIONS FOR RESEARCH Additional evidence from high-quality studies should further examine differences in neonatal outcomes among infants exposed to predominately MOM or DHM in settings using standardized and evidence-based feeding practices.

Abstract
Early life nutrition fundamentally influences neonatal development and health. Human milk oligosaccharides (HMO) are key components of breast milk but not standard infant formula that support the establishment of the newborn gut microbiota. Using an artificial rearing system, our objective was to test the effect of two HMO on the whole body and organ growth, adiposity, glucose tolerance and faecal microbiota in young rat pups. From postnatal days 4 to 21, Sprague-Dawley rats were randomised to receive one of: (1) CTR (rat milk substitute); (2) 2'FL (CTR + 1·2 g/l 2'-fucosyllactose); (3) 3'SL (CTR + 1·2 g/l 3'-sialyllactose) and (4) 2'FL + 3'SL (CTR + 0·6 g/l 2'-FL + 0·6 g/l 3'-SL). Body weight (BW), bowel movements and food intake were monitored daily, faecal samples collected each week and oral glucose tolerance, body composition and organ weight measured at weaning. No significant differences were observed between groups in growth performance, body composition, organ weight and abundance of dominant faecal microbes. A decreased relative abundance of genus Proteus in week 1 faecal samples and Terrisporobacter in week 3 faecal samples (P < 0·05) was suggestive of a potential pathogen inhibitory effect of 3'SL. Longitudinal changes in the faecal microbiota of artificially reared suckling rats were primarily governed by age (P = 0·001) and not affected by the presence of 2'-FL and/or 3'-SL in rat milk substitutes (P = 0·479). Considering the known protective effects of HMO, further investigation of supplementation with these and other HMO in models of premature birth, extremely low BW or malnutrition may show more pronounced outcomes.

Abstract
Background: Human milk does not meet the nutritional needs to support optimal growth of very preterm infants during the first weeks of life. Nutrient fortifiers are therefore added to human milk, though these products are suspected to increase gut dysmotility. The objective was to evaluate whether fortification with bovine colostrum (BC) improves bowel habits compared to a conventional fortifier (CF) in very preterm infants. Methods: In an unblinded, randomized study, 242 preterm infants (26−31 weeks of gestation) were randomized to receive BC (BC, Biofiber Damino, Gesten, Denmark) or CF (FM85 PreNAN, Nestlé, Vevey, Switzerland) as a fortifier. Stools (Amsterdam Stool Scale), bowel gas restlessness, stomach appearance score, volume, and frequency of gastric residuals were recorded before each meal until 35 weeks post-menstrual age. Results: As intake of fortifiers increased, stools became harder in both groups (p < 0.01) though less in BC infants (p < 0.05). The incidence of bowel gas restlessness increased with laxative treatments and days of fortification in both groups (p < 0.01), but laxatives were prescribed later in BC infants (p < 0.01). With advancing age, stomach appearance scores improved, but more so in BC infants (p < 0.01). Conclusions: Although there are limitations, a minimally processed, bioactive milk product such as BC induced similar or slightly improved bowel habits in preterm infants.

Abstract
Human milk is the gold standard to provide nutritional support for all healthy and sick newborn infants including the very low birth weight (VLBW) infant (<1500 g). It has both nutritional and anti-infective properties which are especially important for these infants at risk for sepsis and necrotizing enterocolitis. Human milk alone is insufficient to meet the nutritional needs for VLBW infants, especially protein and minerals. There is a conundrum between achieving the nutritional, immunologic, developmental, psychological, social, and economic benefit with human milk vs. the inadequate growth with unfortified human milk for VLBW leading to nutritional inadequacy, growth failure and poor neurodevelopmental outcome. The use of multicomponent fortifiers to increase calories and provide additional protein, vitamins, and minerals has been associated with short-term benefits in growth. Most current fortifiers are derived from cow's milk, however there are concerns regarding a possible association between the use of cow's milk-based fortifier and NEC. There is also an exclusive human milk diet with a fortifier derived solely from human milk. There are three approaches for fortifying human milk and include fixed dosage or "blind fortification", adjustable fortification using the blood urea nitrogen as a surrogate for protein nutriture to modify dosage of fortification, and targeted, individualized fortification that is based on periodic human milk analysis.

Abstract
OBJECTIVES Necrotizing enterocolitis (NEC) is a severe intestinal inflammatory disease and a leading cause of morbidity and mortality in NICUs. Management of NEC is variable because of the lack of evidence-based recommendations. It is widely accepted that standardization of patient care leads to improved outcomes. This quality improvement project aimed to decrease variation in the evaluation and management of NEC in a Level IV NICU. METHODS A multidisciplinary team investigated institutional variation in NEC management and developed a standardized guideline and electronic medical record tools to assist in evaluation and management. Retrospective baseline data were collected for 2 years previously and prospectively for 3.5 years after interventions. Outcomes included the ratio of observed-to-expected days of antibiotics and nil per os (NPO) on the basis of the novel guidelines and the percentage of cases treated with piperacillin/tazobactam. Balancing measures were death, surgery, and antifungal use. RESULTS Over 5.5 years, there were 124 evaluations for NEC. Special cause variation was noted in the observed-to-expected antibiotic and NPO days ratios, decreasing from 1.94 to 1.18 and 1.69 to 1.14, respectively. Piperacillin/tazobactam utilization increased from 30% to 91%. There were no increases in antifungal use, surgery, or death. CONCLUSIONS Variation in evaluation and management of NEC decreased after initiation of a guideline and supporting electronic medical record tools, with fewer antibiotic and NPO days without an increase in morbidity or mortality. A quality improvement approach can benefit patients and decrease variability, even in diseases with limited evidence-based standards.

Abstract
Giriş: Anne sütü bebeklerin sağlığı için çok önemlidir. Herhangi bir nedenle anne sütünü alamayan bebeklere donör süt önerilir. Bu nedenle anne sütü bankaları hem bebekler hem de anneler için çok önemli kurumlardır. Bu çalışmanın temel amacı prematüre bebeği olan annelerin anne sütü bankacılığı konusunda bilgi ve görüşlerini belirlemektir.
Gereç ve Yöntem: Araştırma, bebeği prematüre ve yenidoğan yoğun bakım ünitesinde yatan annelerle yapıldı. Örneklemi anketi doldurmayı kabul eden 230 anne oluşturmuştur. Veriler, araştırmacı tarafından hazırlanan 39 sorudan oluşan anket ile toplanmıştır. Araştırmanın analiz aşamasında tanımlayıcı istatistikler ve ki-kare testi kullanılmıştır.
Bulgular: Annelerin %86,1'inin anne sütü bankasını duymadığı, %90'ının bilmediği ve anne sütü bankasının kurulmasını isteme konusunda annelerin %43,9'unun kararsız olduğu saptanmıştır. Ülkemizde anne sütü bankası olması durumunda annelerin %41,3'ü süt bağışlamayacağını, %66,5'i süt bankasından süt talep etmeyeceğini ifade etmiştir. Annelerin %48,3'ü süt bankalarının din açısından herhangi bir sorun yaratıp yaratmayacağını bilmediklerini ifade etmiştir. Son olarak annelerin %58,3'ünün süt bankaları hakkında daha fazla bilgi talep ettiği görülmüştür.Annelerin eğitim düzeyi ile süt bankası ön bilgisi, süt bankası kurulmasına destek, süt bankasına ihtiyaç, süt bağışı ve süt talepleri arasında anlamlı bir istatistiksel oran bulunmuştur.
Sonuç: Annelerin büyük bir çoğunluğunun anne sütü bankacılığı konusunda yeterli bilgiye sahip olmadığı saptanmıştır. Annelerin süt bankasının kurulmasını isteme konusunda çoğunlukla kararsız oldukları görülmüştür. Eğitim durumu arttıkça anne sütü bankasına karşı annelerin daha olumlu bir görüş içinde olduğu söylenebilir. Toplumun süt bankacılığı konusunda endişelerinin ortadan kaldırılıp ve bu konuda bilgilendirilmesi gerekmektedir.

Abstract
Milk fortifiers help meet the nutritional needs of preterm infants receiving their mother's own milk (MOM) or donor human milk. We conducted a randomized clinical trial (NCT03214822) in 30 very low birth weight premature neonates comparing bovine-derived human milk fortifier (BHMF) versus human-derived fortifier (H2MF). We found that fortifier type does not affect the overall microbiome, although H2MF infants were less often colonized by an unclassified member of Clostridiales Family XI. Secondary analyses show that MOM intake is strongly associated with weight gain and microbiota composition, including Bifidobacterium, Veillonella, and Propionibacterium enrichment. Finally, we show that while oxidative stress (urinary F2-isoprostanes) is not affected by fortifier type or MOM intake, fecal calprotectin is higher in H2MF infants and lower in those consuming more MOM. Overall, the source of human milk (mother versus donor) appears more important than the type of milk fortifier (human versus bovine) in shaping preterm infant gut microbiota.

Abstract
Introduction: The admission of neonates to Neonatal Intensive Care Units (NICUs) has been identified as a primary inhibiting factor in the establishment of breastfeeding. The aims of this study were to (1) estimate the prevalence and duration of breastfeeding in infants/toddlers who had been admitted to an NICU in Greece and (2) to investigate factors, associated with the NICU stay, which affected the establishment and maintenance of breastfeeding in infants/toddlers previously admitted to the NICU. Materials and methods: Data for this cohort study were retrieved from interviews with mothers of infants/toddlers who had been admitted to our NICU as neonates during the period of 2017−2019. Interviews were conducted based on a questionnaire regarding the child’s nutrition from birth to the day of the interview, including previous maternal experience with breastfeeding. Information related to the prenatal period, gestation age, delivery mode, duration of NICU stay, and neonatal feeding strategies during their hospital stay were recorded. Results: The response rate to the telephone interviews was 57%, resulting in 279 mother−infant pairs being included in this study. The results showed that 78.1% of children received maternal milk during their first days of life. Of all infants, 58.1% were exclusively breastfed during their first month, with a gradual decrease to 36.9% and 19.4% by the end of the third and sixth months of life, respectively. The prevalence of breastfed children reached 14.7% and 7.5% at the ages of twelve and eighteen months, respectively. In the multivariate analysis, prematurity emerged as an independent prognostic factor for the duration of exclusive and any breastfeeding (aHR 1.64, 95% CI: 1.03−2.62; and 1.69, 95% CI: 1.05−2.72, respectively; p < 0.05). Additionally, the nationality of the mother, NICU breastfeeding experience, the administration of maternal milk during neonatal hospital stay, and previous breastfeeding experience of the mother were independent prognostic factors for the duration of breastfeeding. Conclusions: Although breastfeeding is a top priority in our NICU, the exclusive-breastfeeding rates at 6 months were quite low for the hospitalized neonates, not reaching World Health Organization (WHO) recommendations. Mothers/families of hospitalized neonates should receive integrated psychological and practical breastfeeding support and guidance.

Abstract
OBJECTIVE To compare the time to full enteral feeds in preterm infants fed exclusive human milk (EHM) - mother's own milk (MOM) fortified with human milk-based fortifier (HMBF), to those who received partial human milk (PHM) - MOM fortified with bovine milk-based fortifier (BMBF), and exclusive formula. STUDY DESIGN A single-center retrospective study of infants with birth weight <1250 g from 2013 to 2018. Data on feeding, growth and other short-term neonatal morbidities were collected. RESULTS On regression analysis, time to full enteral feeds was significantly higher in PHM compared to EHM group (β-coefficient 4.14, 95% CI 0.00-8.29) and formula-fed group compared to EHM (β-coefficient 4.3, 95% CI 0.32-8.20). No significant differences in growth velocity, length of stay and other morbidities were found between the groups. CONCLUSION Infants in EHM had better feeding tolerance and reached their enteral feed goals sooner compared to PHM and formula-fed groups.

Abstract
The benefits of feeding human milk to human infants are well-established. Preterm infants, particularly those born with very low birthweight (VLBW; <1,500 g), are a uniquely vulnerable population at risk for serious, life-threatening complications as well as disruptions in normal growth and development that can affect their lives into adulthood. Feeding VLBW preterm infants an exclusive human milk diet (EHMD) from birth that consists of the mother's own milk or donor human milk plus a nutritional fortifier made exclusively from human milk has been associated with a reduction in morbidity and mortality and improved early growth and developmental metrics. Preliminary evidence suggests that the health benefits of adopting an EHMD (or avoiding cow milk products) early in life may last into adulthood. This review briefly summarizes the history of breastfeeding and describes the available evidence on the benefits of an EHMD among VLBW preterm infants as well as the importance of high-quality manufacturing standards for producing safe and effective human milk-based products.

Abstract
OBJECTIVE Increase the proportion of ≤33 weeks newborns exposed to mother's own milk (MOM) oral care by 12 h of age by 20% over 2 years to support a healthier microbiome. STUDY DESIGN We implemented interventions to support early expression of colostrum and reliable delivery of resultant MOM to premature newborns. Statistical process control charts were used to track progress and provide feedback to staff. Proportions of newborns exposed to MOM by 12 h were compared relative to baseline. RESULTS There were 46, 66, and 46 newborns in the baseline, implementation, and sustainability periods, respectively. The primary outcome improved from 48% to 61% in the implementation period (relative change 1.27, 95% CI 0.89, 1.81, p = 0.2), to 69% in sustainability period (relative to baseline 1.45, 95% CI 1.02, 2.08, p = 0.03). CONCLUSION An interdisciplinary team-based, multicycle, quality improvement intervention resulted in increased rates of early exposure to MOM.

Abstract
OBJECTIVE This study was aimed to evaluate the effect of human milk protein fortifier (HMPF) versus bovine milk protein fortifier (BMPF) on feeding tolerance defined as the time to reach full feeds and necrotizing enterocolitis (NEC) in premature very low birth weight (VLBW) infants. STUDY DESIGN A retrospective review using the BabySteps Database included 493 infants born ≤33 weeks of gestational age and ≤1,250 g (g) birth weight. A total of 218 infants fed a human milk diet (HMD) with BMPF were compared with 275 infants fed an HMD with HMPF. RESULTS Full feeds were reached significantly sooner in the HMPF group (median: 14 vs. 16 days, p = 0.04). Weight at full feeds was significantly lower in the HMPF group (1,060 vs. 1110 g, p = 0.03). CONCLUSION Using HMPF to provide an exclusively HMD allowed VLBW infants to achieve full feeds sooner, but did not affect rate of NEC compared with using a BMPF with an HMD. KEY POINTS · Human milk fortifiers with human milk are better than bovine human milk protein fortifiers.. · Full feeds are reached sooner with a human milk protein fortifier.. · The incidence of NEC did not change with the use of Prolacta..

Abstract
Introduction: Increasing breastfeeding rates is a national health objective, however substantial barriers and disparities continue to exist in breastfeeding initiation and continuation. Our study aim is to identify factors associated with birthing persons' breastfeeding “success” (patients admitted to Labor & Delivery desiring to breastfeed and discharged breastfeeding) and breastfeeding “failure” (patients admitted to Labor & Delivery desiring to breastfeed and discharged exclusively formula feeding). Materials and Methods: We conducted a retrospective cohort study between July 2015 and June 2016. Patients were asked infant feeding plan intentions (breast, formula, combination) upon admission for delivery. Feeding plan was reassessed at discharge from delivery stay and validated to serve as proxy for feeding status at discharge. Logistic regression was used to identify the population(s) most likely to voice intent to breastfeed and to identify predictors of altered breastfeeding intent at discharge. Results: Between July 2015 and June 2016, 6690 patients met criteria for analysis. Patients reporting intent to breastfeed before delivery were more likely Caucasian (p < 0.0001), married (p < 0.001), nulliparous (p < 0.01), privately insured (p < 0.0001), educated (p < 0.0001), and older (p < 0.01) compared with patients not intending to breastfeed. These characteristics were similar in those who were “successful breastfeeders,” that is, breastfeeding at discharge. The strongest predictor of breastfeeding at discharge was intent to breastfeed before delivery (p < 0.0001). African American race was the strongest predictor of nonbreastfeeding intent at admission (p < 0.0001) and conversion to formula feeding by hospital discharge (p < 0.001). Conclusion: Intent to breastfeed before delivery was the strongest predictor of breastfeeding at discharge; thus, prenatal breastfeeding education within the at-risk population is crucial to increasing breastfeeding rates.

Abstract
OBJECTIVES Human milk reduces the incidence of necrotizing enterocolitis (NEC). Prior studies have demonstrated that exogenous surfactant protein-A (SP-A) modulates intestinal inflammation, reduces NEC-like pathology in SP-A-deficient (SPAKO) pups, and may contribute to breast milk's immunomodulatory potential. We hypothesize that SP-A is present in milk and impacts inflammatory responses in the terminal ileum of neonatal mice. METHODS Human milk was collected at postpartum days 1-3 and 28. Mouse milk was collected at postpartum days 1-10. SP-A was detected in milk through immunoprecipitation and western blot analysis. The impact of murine wild-type (WT) milk on SPAKO pup ileum was evaluated in a model of intestinal inflammation via cross-rearing experiments. Terminal ileum was evaluated for inflammatory cytokine and toll-like receptor 4 (TLR4) mRNA expression via quantitative real-time RT-PCR. RESULTS SP-A was detected in human milk and wild type (WT) mouse milk, but not in SPAKO mouse milk. Expression of TLR4, interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α was decreased in SPAKO pups reared with WT dams compared to SPAKO pups reared with SPAKO dams, with a peak effect at day of life 14. When inflammation was induced using a lipopolysaccharide-induced model of inflammation, expression of TLR4, IL-1β, IL-6, CXCL-1, and TNF-α was significantly lower in SPAKO pups reared with WT dams compared to SPAKO pups reared with SPAKO dams. CONCLUSIONS SP-A is present in human and murine milk and plays a role in lowering inflammation in murine pup terminal ileum. Both baseline inflammation and induced inflammatory responses are reduced via exposure to SP-A in milk with the effect amplified in inflammatory conditions.

Abstract
Human milk (HM) is the best feeding option for preterm infants; however, when mother’s own milk (MOM) is not available, pasteurized donor human milk (DHM) is the best alternative. In this study, we profiled DHM microbiota (19 samples) using 16S rRNA amplicon sequencing and compared its compositional features with the MOM microbiota (14 samples) from mothers who delivered prematurely (PT-MOM). As a secondary study aim, we assessed the specific effect of pasteurization on the characteristics of the DHM microbiota. DHM showed significantly higher alpha diversity and significant segregation from PT-MOM. Compositionally, the PT-MOM microbiota had a significantly higher proportion of Staphylococcus than DHM, with Streptococcus tending to be and Pseudomonas being significantly overrepresented in DHM compared with the PT-MOM samples. Furthermore, pasteurization affected the HM microbiota structure, with a trend towards greater biodiversity and some compositional differences following pasteurization. This pilot study provided further evidence on the HM microbial ecosystem, demonstrating that the DHM microbiota differs from the PT-MOM microbiota, possibly due to inherent differences between HM donors and mothers delivering prematurely, and that pasteurization per se impacts the HM microbiota. Knowledge about HM microbiota needs to be acquired by investigating the effect of DHM processing to develop strategies aimed at improving DHM quality while guaranteeing its microbiological safety.

Abstract
Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease of the premature infant with high mortality and morbidity. Children who survive NEC have been shown to demonstrate neurodevelopmental delay, with significantly worse outcomes than from prematurity alone. The pathways leading to NEC-associated neurological impairments remain unclear, limiting the development of preventative and protective strategies. This review aims to summarize the existing clinical and experimental studies related to NEC-associated brain injury. We describe the current epidemiology of NEC, reported long-term neurodevelopmental outcomes among survivors, and proposed pathogenesis of brain injury in NEC. Highlighted are the potential connections between hypoxia-ischemia, nutrition, infection, gut inflammation, and the developing brain in NEC.

Abstract
INTRODUCTION Breast feeding is recommended for the first year of a baby's life due to numerous benefits for both the child and mother. After returning from maternity leave, surgical trainees face extensive barriers to breast feeding and tend to terminate breast feeding earlier than guideline recommendations. The aim of this scoping review is to assess existing breastfeeding policies for surgical trainees at the national level including postgraduate medical education offices, provincial resident unions and individual surgical programmes. METHODS AND ANALYSIS A modified Arksey and O'Malley (2005) framework will be used. Specifically, (1) identifying the research question/s and (2) relevant studies from electronic databases and grey literature, (3) identifying and (4) selecting studies with independent verification, and (5) collating, summarising, and reporting data while having ongoing consultation between experts throughout the process. Experts will include a lactation consultant (AGB), a human resource leader (JI), a health information specialist (ES), two independent coders (NZ, LR) and a board-certified surgeon (JD). This work will take place as of December 2020 and be carried out to completion in 2021. ETHICS AND DISSEMINATION Ethics approval will not be sought for this scoping review. Research findings will be disseminated through publications, presentations and meetings with relevant stakeholders.

Abstract
In 2012, the American Academy of Pediatrics stated that all preterm infant diets should consist of human milk (mother's own milk or pasteurized donor human milk). The clinical reasons supporting this policy are many, including reducing infections and retinopathy of prematurity, decreased neonatal intensive care unit length of stay, subsequent readmissions, a decrease in mortality, and improved neurodevelopmental outcomes. This article focuses on human milk, its composition and bioactive factors, and how it affects the gut-brain axis through the microbiome. We examine how differences between mother's own milk and pasteurized donor human milk affect the premature infant.

Abstract
Human milk (HM) with appropriate fortification is the recommended nutrition for very low birth weight (VLBW) infants. Fortification provides additional nutrients, vitamins, and minerals to support the growing preterm infant during critical periods of development. This article discusses the variability of HM including differences between maternal and pasteurized donor human milk (DHM), fortification of HM through the use of single- and multi-nutrient fortifiers, and clinical controversies including the timing of fortification, volume of feedings, and future innovations in HM fortification.

Nutrients 2022; 14:nu14091779.

Abstract
Necrotizing enterocolitis (NEC), an inflammatory disease of the intestine, is a common gastrointestinal emergency among preterm infants. Intestinal barrier dysfunction, hyperactivation of the premature immune system, and dysbiosis are thought to play major roles in the disease. Human milk (HM) is protective, but the mechanisms underpinning formula feeding as a risk factor in the development of NEC are incompletely understood. Hyaluronic acid 35 kDa (HA35), a bioactive glycosaminoglycan of HM, accelerates intestinal development in murine pups during homeostasis. In addition, HA35 prevents inflammation-induced tissue damage in pups subjected to murine NEC, incorporating Paneth cell dysfunction and dysbiosis. We hypothesized HA35 treatment would reduce histological injury and mortality in a secondary mouse model of NEC incorporating formula feeding. NEC-like injury was induced in 14-day mice by dithizone-induced disruption of Paneth cells and oral gavage of rodent milk substitute. Mortality and histological injury, serum and tissue cytokine levels, stool bacterial sequencing, and bulk RNA-Seq comparisons were analyzed. HA35 significantly reduced the severity of illness in this model, with a trend toward reduced mortality, while RNA-Seq analysis demonstrated HA35 upregulated genes associated with goblet cell function and innate immunity. Activation of these critical protective and reparative mechanisms of the small intestine likely play a role in the reduced pathology and enhanced survival trends of HA-treated pups subjected to intestinal inflammation in this secondary model of NEC, providing potentially interesting translational targets for the human preterm disease.

Abstract
Background: Preterm birth is associated with an increased risk of many complications, which is a main public health problem worldwide with social and economic consequences. Human milk from breast feeding has been proved to be the optimal nutrition strategy for preterm infants when available. However, the lack of human milk from mothers makes formula widely used in clinical practice. In recent years, donated breast milk has gained popularity as an alternative choice which can provide human milk oligosaccharides and other bioactive substances. Objective: We aimed to conduct a systematic review and meta-analysis to evaluate the nutritional effects of donated breast milk on preterm infants compared with formula. Method: In the present study, we searched Medline, Web of Science, Embase, clinicaltrials.gov, the China national knowledge infrastructure, and the Cochrane central register of controlled trials for candidate randomized controlled trials (RCTs). Results: A total of 1390 patients were enrolled in 11 RCTs and meta-analysis results showed that donated breast milk is also more advantageous in reducing the incidence of necrotizing enterocolitis (NEC, RR = 0.67, 95% CI = 0.48 to 0.93, p = 0.02), reducing the duration of parenteral nutrition (MD = −2.39, 95% CI = −3.66 to −1.13, p = 0.0002) and the time of full enteral feeding (MD = −0.33, 95% CI = −3.23 to 2.57, p = 0.0002). In comparison, formula significantly promotes the growth of premature infants, including their weight gain (MD = −3.45, 95% CI = −3.68 to −3.21, p < 0.00001), head growth (MD = −0.07, 95% CI = −0.08 to −0.06, p < 0.00001) and body length (MD = −0.13, 95% CI = −0.15 to −0.11, p < 0.00001), and reduces the time it takes for premature infants to regain birth weight (MD = 6.60, 95% CI = 6.11 to 7.08, p < 0.00001. Conclusion: Compared with formula, donated breast milk could significantly reduce the incidence of NEC, the duration of parenteral nutrition, and the time of full enteral feeding. Adding fortifiers in donated milk could make it as effective as formula in promoting the physical growth of premature infants.

This study aimed to assess the impact of health education on the caring practices of low-birthweight (LBW) infant mothers in Central Jakarta, Indonesia. A quasi-experiment design with a pretest-post-test control group model was conducted on 159 mothers (78 in the intervention group and 81 in the control group) of LBW infants treated in the perinatology ward of three hospitals in Central Jakarta. Provision of health education to mothers of LBW infants consisted of counselling sessions and one-on-one visits provided by primary health centre nurses. Data were collected four times consecutively over 6 weeks. A generalized estimating equation model with a linear link function was employed to examine LBW infant practice score changes due to intervention and other influential factors at four time points. Results: The LBW infant care practice scores were higher in the intervention group than in the control group at each measurement point. After controlling for maternal attitudes, LBW infant health education increased mothers' infant care practices at 2, 6 and 12 weeks by 2.179, 2.803 and 2.981 points, respectively, and reduced infant morbidity. Six weeks of health education had an effective impact on mothers' home LBW infant care practices and infant health status.

Abstract
BackgroundBreastfed infants have a reduced risk of infections and allergies. The study of chrononutrition in human milk seeks to understand the circadian variation of various human milk immune factors.MethodsEmpirical studies on human milk, chrononutrition, and immune factors were searched through PUBMED, Google Scholar, and SCOPUS. Keywords included “chrononutrition,” “breastmilk composition,” “human milk,” “day-night cycles,” “sleep-wake cycles” and the names of various immune factors. After excluding duplicate articles, animal studies, studies looking at other human milk components, studies that did not collect human milk samples over a 24 hour period, and studies that were not in English, eleven studies on the topic remained and ten studies were included in the review. The excluded study had a sample size of two.ResultsThis review identified the circadian variation of certain immune factors found in human milk such as antibodies, complement proteins, cytokines, by-products of phagocyte activity, nucleotides, microRNAs, and antioxidants.ConclusionThe circadian variation observed in some human milk components highlights the unique ability of human milk to vary in composition based on the circadian rhythms of mothers and infants. The limited number of studies makes it difficult to make conclusive recommendations and creates an opportunity for further research in this growing field.

Impact of pasteurization on the self-assembly of human milk lipids during digestion. J Lipid Res 2022; 63:100183.

Abstract
Human milk is critical for the survival and development of infants. This source of nutrition contains components that protect against infections while stimulating immune maturation. In cases where the mother's own milk is unavailable, pasteurized donor milk is the preferred option. Although pasteurization has been shown to have minimal impact on the lipid and FA composition before digestion, no correlation has been made between the impact of pasteurization on the FFA composition and the self-assembly of lipids during digestion, which could act as delivery mechanisms for poorly water-soluble components. Pooled nonpasteurized and pasteurized human milk from a single donor was used in this study. The evolving FFA composition during digestion was determined using GC coupled to a flame ionization detector. In vitro digestion coupled to small-angle X-ray scattering was utilized to investigate the influence of different calcium levels, fat content, and the presence of bile salts on the extent of digestion and structural behavior of human milk lipids. Almost complete digestion was achieved when bile salts were added to the systems containing high calcium to milk fat ratio, with similar structural behavior of lipids during digestion of both types of human milk being apparent. In contrast, differences in the colloidal structures were formed during digestion in the absence of bile salt because of a greater amount of FFAs being released from the nonpasteurized than pasteurized milks. This difference in FFAs released from both types of human milk could result in varying nutritional implications for infants.

Abstract
Appropriate nutrition is essential for optimal development and growth of preterm infants. Infants less than 25 weeks corrected gestational age are frequently the most difficult group for which to provide adequate nutrition due to minimal energy stores and high fluid losses. Nutrient delivery becomes an integral, but also very challenging part in their management. Early administration of intravenous nutrients provides a critical bridge to full enteral nutrition. However, enteral feeding is challenging due to immaturities of the intestinal tract, feeding intolerance and the risk of catastrophic gastrointestinal disease such as necrotizing enterocolitis (NEC). Decreased gastric acid production, increased gut permeability, reduced immunoglobulins, immature intestinal epithelia and a decreased mucin barrier all contribute to weakness to gastrointestinal insult. This review aims to illustrate the importance of enteral feeding and the common challenges and approaches in the nutrition of infants born at this age.

Abstract
Necrotizing enterocolitis (NEC) is a disease mainly of preterm infants with a 30-50% mortality rate and long-term morbidities for survivors. Treatment strategies are limited and have not improved in decades, prompting research into prevention strategies, particularly with probiotics. Recent work with the probiotic B. infantis EVC001 suggests that this organism may generate a more appropriate microbiome for preterm infants who generally have inappropriate gut colonization and inflammation, both risk factors for NEC. Experimental NEC involving Paneth cell disruption in combination with bacterial dysbiosis or formula feeding was induced in P14-16 C57Bl/6 mice with or without gavaged B. infantis. Following completion of the model, serum, small intestinal tissue, the cecum, and colon were harvested to examine inflammatory cytokines, injury, and the microbiome, respectively. EVC001 treatment significantly decreased NEC in a bacterial dysbiosis dependent model, but this decrease was model-dependent. In the NEC model dependent on formula feeding, no difference in injury was observed, but trending to significant differences was observed in serum cytokines. EVC001 also improved wound closure at six and twelve hours compared to the sham control in intestinal epithelial monolayers. These findings suggest that B. infantis EVC001 can prevent experimental NEC through anti-inflammatory and epithelial barrier restoration properties.

Abstract
Human milk oligosaccharides (HMOs) have been researched by scientists for over 100 years, driven by the substantial evidence for the nutritional and health benefits of mother's milk. Yet research has truly bloomed during the last decade, thanks to the progress in biotechnology, which allowed the production of large amounts of bona fide HMOs. The availability of HMOs has been particularly crucial for the renewed interest in HMO research because of the low abundance or even absence of HMOs in farmed animal milk. This interest is reflected in the increasing number of original research publications and reviews on HMOs. Here, we provide an overview and critical discussion on structure function relations of HMOs that highlight why they are such interesting and important components of human milk. Clinical observations in breastfed infants backed by basic research from animal models provide guidance as to what physiological roles for HMOs are to be expected. From an evidence-based nutrition viewpoint, we discuss the current data supporting clinical relevance of specific HMOs based on randomized placebo controlled clinical intervention trials in formula-fed infants.

Abstract
An exclusive human milk diet (EHMD) has been shown to reduce health complications of prematurity in infants born weighing ≤1250 g compared with cow milk-based diets. Accordingly, the number of available human milk (HM)-based nutritional products continues to increase. Newly available products, and those reportedly soon to enter the market, include homogenized donor HM and homogenized HM-based fortifiers. Existing literature demonstrating the benefits of an EHMD, however, is limited to non-homogenized HM-based products. Herein, we summarize existing evidence on the impact of homogenization on HM, with a particular focus on changes to the macromolecular structure of the milk fat globule and the subsequent impact on digestion kinetics. We use these published data to create a conceptual framework for the potential implications of homogenized HM-based nutritional products on preterm infant health. Importantly, we underscore that the safety and efficacy of homogenized HM-based products warrant investigation.

Abstract
Amniotic fluid (AF) is the first fluid to enter the gastrointestinal tract. Preterm birth is leading to a sudden interruption of AF swallowing. Understanding the composition of amniotic fluid is crucial to implement strategies preventing intestinal injury in preterm infants. We hypothesized that the fetal gastrointestinal tract (GIT) is exposed to melatonin and antioxidant enzymes via amniotic fluid throughout prenatal development. Amniotic fluid samples from 76 pregnant women with a median (range) gestational age of 38.0 (14.3–40.1) weeks have been collected. Immediately after birth blood samples were collected from the umbilical vein (n = 53). Median (Interquartile range) melatonin concentration was 30.5 pg/ml (12.7–118.3) and superoxide dismutase 1 (SOD1) concentration was 84 ng/ml (59–123). Extracellular glutathione peroxidase concentration was either not detectable or exceptionally low. We found a positive correlation between melatonin concentration in amniotic fluid and gestational age (Spearman’s correlation coefficient, r = 0.570, p<0.001), while SOD1 concentration in amniotic fluid was inversely correlated with gestational age (r = −0.246, p = 0.032). Compared to serum samples, melatonin concentration was statistically significantly higher in amniotic fluid (p<0.001). Our results indicate that the fetal gastrointestinal system is continuously exposed to melatonin and SOD1 via the amniotic fluid throughout prenatal development.

Abstract
BACKGROUND Exosomes are nanosized extracellular vesicles, that play important roles in intercellular immune regulation. They have potential therapeutic utility for neonatal diseases including necrotizing enterocolitis. Breast-milk-derived exosomes have recently shown beneficial effects on intestinal damage in vitro and in vivo. However, the chronological change in breast-milk-derived exosome concentrations after delivery are unclear. METHODS In this prospective study, we enrolled 17 mothers who delivered premature infants admitted to a neonatal intensive care unit in Japan. We measured the consecutive concentrations of breast-milk-derived exosomes in the mothers for 48 weeks after delivery. RESULTS The median concentration of breast-milk-derived exosomes was 1.62 × 108 particles/ml in colostrum, showing a significant decrease after 2 weeks (P < 0.01). There was no association between the exosome concentration in colostrum and maternal perinatal factors including parity, mode of delivery, maternal age, and gestational age at delivery. CONCLUSIONS We concluded that breast-milk-derived exosomes were the richest in colostrum. Our basic data regarding breast-milk-derived exosomes are expected to aid in the clinical application of exosomes for treating neonatal diseases.

Abstract
AIM To investigate the use of human milk fortifier (HMF) for very preterm infants (VPIs) and complications and nutritional status of VPIs due to various breast milk enhancement strategies among the Chinese population. METHODS VPIs with birth weight < 1,800 g and wholly or predominantly breastfed were assigned to the following fortification groups: no HMF, early HMF (adding HMF at an enteral volume of ≤ 80 ml·kg-1·day-1), middle HMF (adding HMF at an enteral volume of 80-100 ml·kg-1·day-1), and late HMF (adding HMF at an enteral volume of ≥100 ml·kg-1·day-1). The growth status and complications for various groups were evaluated. RESULTS We enrolled 985 VPIs, of which 847 VPIs (86.0%) received HMF, whereas 138 VPIs (14.0%) did not. The number of VPIs in the early, middle, and late fortification groups were 89 (9.0%), 252 (25.6%), and 506 (51.4%), respectively. The complete fortification of the early, middle, and late fortification groups was achieved in 13.2 ± 11.0, 13.8 ± 11.7, and 12.3 ± 13.0 days, respectively, without significant differences (p > 0.05). The groups did not exhibit significant differences in the incidence of feeding intolerance, necrotizing enterocolitis (Bell stage ≥ 2), late-onset sepsis, and metabolic bone diseases (p > 0.05). The middle fortification groups exhibited the fastest growth velocity and the least dramatic decrease in the Z-score of weight and length, and the lowest incidence of EUGR (35.7%), whereas the "no HMF" groups exhibited the slowest growth velocity and the largest decline in the Z-score, and the highest incidence of EUGR (61.6%). CONCLUSIONS The usage rate of HMF was relatively low among Chinese VPIs, fortification often occurred in the late feeding stage, and the time to reach complete fortification was long. Adding HMF and different breast milk enhancement strategies did not increase the incidence of feeding intolerance and necrotizing enterocolitis. The enteral volume of 80-100 ml·kg-1·day-1 with HMF addition led to increased growth in the weight and length and lower EUGR incidence, indicating that the addition of HMF at the specific feeding volume might be the best practice for promoting growth.

Neurodevelopmental outcomes of extremely preterm infants fed an exclusive human milk-based diet versus a mixed human milk + bovine milk-based diet: a multi-center study. J Perinatol 2022; 42:1485-1488. [PMID: 36171356 PMCID: PMC9616714 DOI: 10.1038/s41372-022-01513-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 07/07/2022] [Accepted: 09/07/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVE The objective of this multi-center study was to compare, in infants ≤1250 g birth weight (BW) with neurodevelopmental assessment at 18-22 months of corrected age (CA), whether their neurodevelopmental outcomes differed based on exposure to an exclusive human milk-based (HUM) or to a bovine milk-based fortifier and/or preterm formula (BOV). STUDY DESIGN Retrospective multi-center cohort study of infants undergoing neurodevelopmental assessment as to whether HUM or BOV exposure related to differences in outcomes of infants at 18-22 months CA, using the Bayley Scales of Infant Development III (BSID-III). BSID-III cognitive, language, and motor scores were adjusted for BW, sex, study site, and necrotizing enterocolitis. RESULTS 252 infants from 6 centers were included. BSID-III cognitive scores were higher in the HUM group (96.5 ± 15.1 vs 89.6 ± 14.1, adjusted p = 0.0001). Mean BSID-III language scores were 85.5 ± 15.0 in HUM and 82.2 ± 14.1 in BOV (adjusted p = 0.09). Mean BSID-III motor scores were 92.9 ± 11.7 in HUM and 91.4 ± 14.6 in BOV (adjusted p = 0.32). CONCLUSION In this cohort of infants undergoing neurodevelopmental assessment, infants receiving HUM diet had significantly higher cognitive BSID-III scores at 18-22 months CA. Further investigation is needed of this potential for HUM to positively influence infant cognitive outcomes.

J Paediatr Child Health 2022; 58:30-38. [PMID: 34669996 DOI: 10.1111/jpc.15810] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 06/15/2021] [Accepted: 10/05/2021] [Indexed: 01/18/2023]
Abstract
AIM To assess effects of early versus delayed introduction of human milk fortification in preterm infants. METHODS We searched Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PubMed and CINAHL for randomised controlled trials evaluating start time for human milk fortification in preterm infants (March 2020). Two authors assessed trial eligibility and risk of bias, extracted data and assessed evidence certainty. RESULTS We identified 1307 publications and included three trials (378 infants). Meta-analysis comparing fortification commencing at an enteral feed volume of ≤40 mL/kg/day versus ≥75 mL/kg/day, showed little to no difference in rates of necrotising enterocolitis (3 trials), sepsis (3 trials), feeding intolerance (2 trials) (low-quality evidence) and infant growth (1 trial, very low-quality evidence). CONCLUSIONS Whether early introduction of fortification, at an enteral feed volume of ≤40 mL versus delayed at ≥75 mL/kg/day improves growth or influences adverse feeding outcomes is very uncertain.

Human milk feeding and cognitive outcome in preterm infants: the role of infection and NEC reduction. Pediatr Res 2022; 91:1207-1214. [PMID: 34168271 PMCID: PMC9122812 DOI: 10.1038/s41390-021-01367-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 11/17/2020] [Accepted: 12/05/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Breast milk has been associated with lower risk of infection and necrotising enterocolitis (NEC) and improved long-term cognitive outcomes in preterm infants but, if unsupplemented, does not meet the nutritional requirements of preterm infants. METHODS Preterm infants were randomised to receive a high nutrient intervention diet: preterm formula (PTF) or the standard diet: term formula (TF) or banked donor breast milk (BBM), either as their sole diet or as supplement to maternal breast milk (MBM). IQ tests were performed at ages 7, 15, 20, and 30 years. RESULTS An increase in MBM and BBM intake was associated with a lower chance of neonatal infection/NEC. Neonatal infection/NEC was associated with lower Full Scale IQ (FSIQ) and Performance IQ (PIQ) score at ages 7 and 30 years. The relationship between higher intake of MBM and PIQ at age 7 years was partly mediated by neonatal infection/NEC. The intervention diet was associated with higher Verbal IQ (VIQ) scores compared to the standard diet. There was no evidence that these effects changed from childhood through to adulthood. CONCLUSIONS Neonatal diet is an important modifiable factor that can affect long-term cognitive outcome through a 'human milk' factor, protecting against infection/NEC, and a 'nutrient content' factor. IMPACT This is the first study to demonstrate the effects of neonatal infection/necrotising enterocolitis (NEC) on IQ in the same cohort in childhood and adulthood. Diet can be a key factor in long-term cognitive outcome in people born preterm by preventing neonatal infection/NEC and providing adequate nutrients. Human milk, whether MBM or BBM, is associated with a reduced risk of infection/NEC. A higher nutrient diet is associated with better cognitive outcome in childhood. Performance IQ is particularly vulnerable to the effects of infection/NEC and verbal IQ to the quantity of (macro)nutrients in the diet.
