Abstract
BACKGROUND When sufficient maternal milk is not available, donor human milk or formula are the alternative forms of enteral nutrition for very preterm or very low-birthweight (VLBW) infants. Donor human milk may retain the non-nutritive benefits of maternal milk and has been proposed as a strategy to reduce the risk of necrotising enterocolitis (NEC) and associated mortality and morbidity in very preterm or VLBW infants. OBJECTIVES To assess the effectiveness of donor human milk compared with formula for preventing NEC and associated morbidity and mortality in very preterm or VLBW infants when sufficient maternal milk is not available. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Maternity and Infant Care (MIC) database, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), from the earliest records to February 2024. We searched clinical trials registries and examined the reference lists of included studies. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing feeding with donor human milk versus formula in very preterm (< 32 weeks' gestation) or VLBW (< 1500 g) infants. DATA COLLECTION AND ANALYSIS Two review authors evaluated the risk of bias in the trials, extracted data, and synthesised effect estimates using risk ratio, risk difference, and mean difference, with associated 95% confidence intervals. The primary outcomes were NEC, late-onset invasive infection, and all-cause mortality before hospital discharge. The secondary outcomes were growth parameters and neurodevelopment. We used the GRADE approach to assess the certainty of the evidence for our primary outcomes. MAIN RESULTS Twelve trials with a total of 2296 infants fulfilled the inclusion criteria. Most trials were small (average sample size was 191 infants). All trials were performed in neonatal units in Europe or North America. Five trials were conducted more than 40 years ago; the remaining seven trials were conducted in the year 2000 or later. Some trials had methodological weaknesses, including concerns regarding masking of investigators and selective reporting. Meta-analysis showed that donor human milk reduces the risk of NEC (risk ratio (RR) 0.53, 95% confidence interval (CI) 0.37 to 0.76; I² = 4%; risk difference (RD) -0.03, 95% CI -0.05 to -0.01; 11 trials, 2261 infants; high certainty evidence). Donor human milk probably has little or no effect on late-onset invasive infection (RR 1.12, 0.95 to 1.31; I² = 27%; RD 0.03, 95% CI -0.01 to -0.07; 7 trials, 1611 infants; moderate certainty evidence) or all-cause mortality (RR 1.00, 95% CI 0.76 to 1.31; I² = 0%; RD -0.00, 95% CI -0.02 to 0.02; 9 trials, 2116 infants; moderate certainty evidence). AUTHORS' CONCLUSIONS The evidence shows that donor human milk reduces the risk of NEC by about half in very preterm or VLBW infants. There is probably little or no effect on late-onset invasive infection or all-cause mortality before hospital discharge.

Lata M, Ramya T. A comparative study of the substrate preference of the sialidases, CpNanI, HpNanH, and BbSia2 towards 2-Aminobenzamide-labeled 3'-Sialyllactose, 6'-Sialyllactose, and Sialyllacto-N-tetraose-b. Biochem Biophys Rep 2024; 39:101791. [PMID: 39156723 PMCID: PMC11326918 DOI: 10.1016/j.bbrep.2024.101791] [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: 05/24/2024] [Revised: 07/15/2024] [Accepted: 07/16/2024] [Indexed: 08/20/2024] Open
Abstract
Sialidases catalyze the removal of terminal sialic acids from sialylated biomolecules, and their substrate preference is frequently indicated in terms of the glycosidic linkages cleaved (α2-3, α2-6, and α2-8) without mention of the remaining sub-terminal reducing-end saccharide moieties. Many human gut commensal and pathogenic bacteria secrete sialidases to forage for sialic acids, which are then utilized as an energy source or assimilated into membrane/capsular structural components. Infant gut commensals similarly utilize sialylated human milk oligosaccharides containing different glycosidic linkages. Here, we have studied the preference of the bacterial sialidases, BbSia2 from Bifidobacterium bifidum, CpNanI from Clostridium perfringens, and HpNanH from Glaesserella parasuis, for the glycosidic linkages, Siaα2-3Gal, Siaα2-6Gal, and Siaα2-6GlcNAc, by employing 2-Aminobenzamide-labeled human milk oligosaccharides, 3'-Sialyllactose (3'-SL), 6'-Sialyllactose (6'-SL), and Sialyllacto-N-tetraose-b (LSTb), respectively, as proxies for these glycosidic linkages. BbSia2, CpNanI, and HpNanH hydrolyzed these three oligosaccharides with the glycosidic linkage preferences, 3'-SL (Siaα2-3Gal) ≥ LSTb (Siaα2-6GlcNAc) ≥ 6'-SL (Siaα2-6Gal), 3'-SL (Siaα2-3Gal) ≥ 6'-SL (Siaα2-6Gal) > LSTb (Siaα2-6GlcNAc), and 3'-SL (Siaα2-3Gal) ≥ 6'-SL (Siaα2-6Gal) > LSTb (Siaα2-6GlcNAc), respectively. Our finding suggests that sub-terminal reducing-end saccharide moieties can profoundly influence the substrate preference of sialidases, and advocates for the characterization and indication of the substrate preference of sialidases in terms of both the glycosidic linkage and the sub-terminal reducing-end saccharide moiety.

Abstract
OBJECTIVE In 2017, our Level IV NICU switched from providing bovine-derived (BOV-fort) to human milk-derived fortifiers (HM-fort) and donor human milk (DHM) to premature infants born ≤ 30 weeks or ≤1250 g. Following this change, providers anecdotally observed increased hypoglycemia, hypercalcemia, and hyperphosphatemia. This study investigated potential laboratory differences between infants fed Bovine vs. Human milk derived fortifier. METHODS Lab measurements from 402 infants (232 BOV-fort, 170 HM-fort) born between 2015 and 2019 were compared between groups. RESULTS The proportion of infants ever having a blood glucose ≤ 45 mg/dL (p < 0.0001) was higher in the HM-fort group. The proportion of infants ever experiencing a phosphorus > 8.0 mg/dL were higher in the HM-fort group (p < 0.0001). The proportion of infants ever experiencing calcium > 11.4 mg/dL was higher in the HM-Fort group (p = 0.019). CONCLUSIONS Provision of HM-Fort and DHM to extremely premature infants is associated with metabolic derangements.

Adjusted versus Targeted Fortification in Extremely Low Birth Weight Preterm Infants: Fortin Study-A Randomized Clinical Trial. Nutrients 2024; 16:2904. [PMID: 39275220 DOI: 10.3390/nu16172904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 08/23/2024] [Accepted: 08/29/2024] [Indexed: 09/16/2024] Open
Abstract
Fortified human milk is the first choice for preterm infants. Although individualized fortification is recommended, the optimal method for this population remains uncertain. We conducted a comparative study assessing the growth effects of adjusted (AF) and targeted fortification (TF) in extremely low birth weight (ELBW) infants. This single-center, randomized, controlled clinical trial was conducted at a tertiary neonatal unit in Spain. Eligible participants were premature infants with a birthweight of <1000 g exclusively fed with human milk. A total of 38 patients were enrolled, 15 of them randomized to AF group and 23 to TF group. AF was based on blood urea nitrogen (BUN) concentration and TF on human milk analysis. The primary outcome was weight gain velocity (g/kg/day). No significant differences were found in weight gain velocity at 28 days, at 36 weeks of postmenstrual age, at discharge, nor during the intervention. Protein intake was significantly higher in the AF group (5.02 g/kg/day vs. 4.48 g/kg/day, p = 0.001). No differences were found in the lipid, carbohydrate, and energy intake; in the weight z score change between the different time points; nor in the length and head circumference growth. Both AF and TF are comparable methods of fortification and provide the appropriate growth rate in ELBW infants.

Pediatr Res 2024:10.1038/s41390-024-03483-y. [PMID: 39152334 DOI: 10.1038/s41390-024-03483-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Revised: 07/18/2024] [Accepted: 08/01/2024] [Indexed: 08/19/2024]
Abstract
BACKGROUND Use of standardized feeding protocols and donor breast milk (DBM) have been studied primarily in infants born <1500 g and not examined exclusively in infants born >1500 g. METHODS In this retrospective pre-post-implementation cohort study, we evaluated a protocol for preterm infants born >1500 g that was implemented clinically to standardize feeding advancements at 30 mL/kg/day, with infants born <33 weeks eligible to receive DBM. We compared placement of peripherally inserted central catheters for parenteral nutrition, feeding tolerance, growth, and maternal milk provision in the 18 months before/after implementation. The association between DBM intake and growth was evaluated using multivariable linear regression. RESULTS We identified 133 and 148 eligible infants pre/post-implementation. Frequency of peripherally inserted central catheters and rate of maternal milk provision was not statistically different. While there was no difference in median days to full enteral volume, there was a narrower distribution post-implementation (p < 0.001). Growth was similar between eras, but each 10% increase in DBM was associated with 1.0 g/d decrease in weight velocity (p < 0.001). CONCLUSIONS A feeding protocol for preterm infants >1500 g is associated with more consistent time to full enteral volume. Further investigation is needed to clarify DBM's impact on growth in this population. IMPACT Despite practice creep, no study has examined the use of standardized feeding protocols or pasteurized donor breast milk exclusively in infants >1500 g. A feeding protocol in this population may achieve full enteral feedings more consistently. With appropriate fortification, donor breast milk can support adequate growth in infants born >1500 g but warrants further study.

Abstract
Background The effects of blood transfusions on splanchnic oxygenation and complications related to blood transfusions, including red blood cell (RBC) transfusions, in premature infants undergoing enteral feeding, to provide clinical evidence for a management protocol for premature infants during the peri-transfusion period. Methods This single-blind, randomized, controlled trial enrolled sixty eligible preterm infants who were randomly divided into the withholding feeding group (n = 30) or feeding group (n = 30). Enteral feeding was withheld for 8 h, beginning from the start of transfusion infants in the feeding group were fed according to the pre-transfusion feeding approach during and after RBC transfusion. Results Baseline characteristics of those in the withholding and feeding groups were as follows: gestational age (weeks) 27.52 (24.86-30.14) and 27.13 (25.43-30.14); birth weight (g), 1,027 (620-1,450) and 1,027 (620-1,270); blood transfusion day, 48 (14-79) and 39 (10-78); and hemoglobin before blood transfusion (g/L), 81.67 (±10.56) and 85.93 (±14.77). No significant differences were observed between groups at baseline. No significant differences were observed in the average splanchnic tissue oxygenation changes or clinical results at any time. One patient in the withholding feeding group experienced transfusion-associated necrotizing enterocolitis. Conclusions No differences in splanchnic oxygenation observed these feeding protocols. This study suggests the feasibility of a sizable trial to evaluate clinical outcomes. The risks of mesenteric ischemia and transfusion-related necrotizing enterocolitis for premature infants were not increased by enteral feeding during RBC transfusion.

Abstract
The correct initial colonization and establishment of the gut microbiota during the early stages of life is a key step, with long-lasting consequences throughout the entire lifespan of the individual. This process is affected by several perinatal factors; among them, feeding mode is known to have a critical role. Breastfeeding is the optimal nutrition for neonates; however, it is not always possible, especially in cases of prematurity or early pathology. In such cases, most commonly babies are fed with infant formulas in spite of the official nutritional and health international organizations' recommendation on the use of donated human milk through milk banks for these cases. However, donated human milk still does not totally match maternal milk in terms of infant growth and gut microbiota development. The present review summarizes the practices of milk banks and hospitals regarding donated human milk, its safety and quality, and the health outcomes in infants fed with donated human milk. Additionally, we explore different alternatives to customize pasteurized donated human milk with the aim of finding the perfect match between each baby and banked milk for promoting the establishment of a beneficial gut microbiota from the early stages of life.

Abstract
BACKGROUND Vitamin D is essential for bone health and immune system. Vitamin D deficiency (VDD) poses a high-risk to very preterm (VP) infants. This study aimed to evaluate the risk factors associated with VDD in VP infants and its potential clinical outcomes. METHODS A retrospective cohort study was conducted on VP infants admitted to the neonatal intensive care unit of a specialized tertiary hospital in Seoul, Republic of Korea, between January 2018 and June 2022. Serum 25-hydroxyvitamin D (25(OH)D) levels and other biochemical parameters were measured between 4 and 6 weeks of age. VDD was defined as a serum 25(OH)D level <20 ng/mL. Prenatal and postnatal risk factors and clinical outcomes were compared between the VDD and non-VDD groups. RESULTS Of the 82 VP infants analyzed, 27 (32.9%) were diagnosed with VDD. The VDD group exhibited a significantly longer duration of parenteral nutrition (PN) compared to the non-VDD group (adjusted odds ratio [OR] = 1.12; 95% confidence interval [CI]: 1.008-1.245). Breast milk intake was lower in the VDD group than in the non-VDD group (adjusted OR = 0.976, 95% CI, 0.955-0.999). Notably, calcium levels were significantly lower in the VDD group, while parathyroid hormone levels were significantly higher, compared with the non-VDD group. Additionally, the rickets severity score was higher in the VDD group than in the non-VDD, although the difference was not statistically significant. CONCLUSIONS Prolonged PN duration and low breast milk intake significantly increased the risk of VDD in VP infants.

Abstract
Necrotizing enterocolitis (NEC) is a life-threatening disease predominantly affecting premature and very low birth weight infants resulting in inflammation and necrosis of the small bowel and colon and potentially leading to sepsis, peritonitis, perforation, and death. Numerous research efforts have been made to better understand, treat, and prevent NEC. This review explores a variety of factors involved in the pathogenesis of NEC (prematurity, low birth weight, lack of human breast milk exposure, alterations to the microbiota, maternal and environmental factors, and intestinal ischemia) and reports treatment modalities surrounding NEC, including pain medications and common antibiotic combinations, the rationale for these combinations, and recent antibiotic stewardship approaches surrounding NEC treatment. This review also highlights the effect of early antibiotic exposure, infections, proton pump inhibitors (PPIs), and H2 receptor antagonists on the microbiota and how these risk factors can increase the chances of NEC. Finally, modern prevention strategies including the use of human breast milk and standardized feeding regimens are discussed, as well as promising new preventative and treatment options for NEC including probiotics and stem cell therapy.

Human Breast Milk Exosomal miRNAs are Influenced by Premature Delivery and Affect Neurodevelopment. Mol Nutr Food Res 2024; 68:e2300113. [PMID: 38644336 DOI: 10.1002/mnfr.202300113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 02/27/2024] [Indexed: 04/23/2024]
Abstract
SCOPE This study investigates the exosomal microRNA (miRNA) profiles of term and preterm breast milk, including the most abundant and differentially expressed (DE) miRNAs, and their impact on neurodevelopment in infants. METHODS AND RESULTS Mature milk is collected from the mothers of term and preterm infants. Using high-throughput sequencing and subsequent data analysis, exosomal miRNA profiles of term and preterm human breast milk (HBM) are acquired and it is found that the let-7 and miR-148 families are the most abundant miRNAs. Additionally, 23 upregulated and 15 downregulated miRNAs are identified. MiR-3168 is the most upregulated miRNA in preterm HBM exosome, exhibiting targeting activity toward multiple genes involved in the SMAD and MAPK signaling pathways and playing a crucial role in early neurodevelopment. Additionally, the effects of miR-3168 on neurodevelopment is confirmed and it is determined that it is an essential factor in the differentiation of neural stem cells (NSCs). CONCLUSION This study demonstrates that miRNA expression in breast milk exosomes can be influenced by preterm delivery, thereby potentially impacting neurodevelopment in preterm infants.

Abstract
BACKGROUND In very low birth weight (VLBW) infants, human milk cream added to standard human milk fortification is used to improve growth. This study aimed to evaluate the impact of cream supplement on the intestinal microbiome of VLBW infants. METHODS Whole genome shotgun sequencing was performed on stool (n = 57) collected from a cohort of 23 infants weighing 500-1250 grams (control = 12, cream = 11). Both groups received an exclusive human milk diet (mother's own milk, donor human milk, and donor human milk-derived fortifier) with the cream group receiving an additional 2 kcal/oz cream at 100 mL/kg/day of fortified feeds and then 4 kcal/oz if poor growth. RESULTS While there were no significant differences in alpha diversity, infants receiving cream significantly differed from infants in the control group in beta diversity. Cream group samples had significantly higher prevalence of Proteobacteria and significantly lower Firmicutes compared to control group. Klebsiella species dominated the microbiota of cream-exposed infants, along with bacterial pathways involved in lipid metabolism and metabolism of cofactors and amino acids. CONCLUSIONS Cream supplementation significantly altered composition of the intestinal microbiome of VLBW infants to favor increased prevalence of Proteobacteria and functional gene content associated with these bacteria. IMPACT We report changes to the intestinal microbiome associated with administration of human milk cream; a novel supplement used to improve growth rates of preterm very low birth weight infants. Since little is known about the impact of cream on intestinal microbiota composition of very low birth weight infants, our study provides valuable insight on the effects of diet on the microbiome of this population. Dietary supplements administered to preterm infants in neonatal intensive care units have the potential to influence the intestinal microbiome composition which may affect overall health status of the infant.

Abstract
OBJECTIVE Quantify blood fatty acids and growth outcomes in preterm infants fed the exclusive human milk diet. METHODS A prospective cohort study of 30 infants 24-34 weeks gestation and ≤1250 g fed the exclusive human milk diet. Blood fatty acids were quantified at two time points. Comparisons were made using two-sample t-tests and Wilcoxon rank sum. RESULTS Donor human milk-fed (n = 12) compared to mother's own milk-fed infants (n = 18) from birth to after 28 days of life, had an increased interval change of linoleic to docosahexaenoic acid ratio (5.5 vs. -1.1 mole percent ratio, p = 0.034). Docosahexaenoic and eicosapentaenoic acid interval changes were similar between groups. The arachidonic acid change was similar between groups (-2.3 vs. -0.9 mole percent, p = 0.37), however, both experienced a negative change across time. At 36 weeks postmenstrual age, growth velocities were similar for groups. CONCLUSION An exclusive human milk diet maintains birth docosahexaenoic and eicosapentaenoic acid concentrations. However, the postnatal deficit in arachidonic acid was not prevented.

Abstract
BACKGROUND Fatty acids (FAs) in human milk are important nutrients for infants. They play important roles in energy supply, nervous system development, and metabolic function maintenance. However, how the composition of major milk FAs change with lactation stages remains controversial. OBJECTIVES To systematically review the concentration range of major FAs in human milk at various lactation stages. METHODS A total of 12 papers involving 50 sets of data with 3507 participants were reviewed according to the PRISMA checklist and flow diagram. The inclusion criteria was the literatures had the FAs contents in breast milk of healthy lactation mothers at three lactation stages and the dietary patterns could be calculated. The exclusion criteria were: the studies were duplicates, were unrelated to dietary patterns or breast milk composition, and/or the study populations were unhealthy. We searched PubMed, the China National Knowledge Infrastructure, WanFang, and Web of science. Agency for Health Care Research and Quality (AHRQ) was used to assess the bias of studies. The mean values of polyunsaturated fatty acids (PUFAs) including docosahexaenoic acid (DHA), arachidonic acid (AA), eicosapentaenoic acid (EPA), α-linolenic acid (ALA), linoleic acid (LA), monounsaturated fatty acids (MUFAs), and saturated fatty acids (SFAs, including lauric acid and palmitic acid), in human milk at three lactation stages (colostrum 1-7 d, transitional milk 8-14 d, mature milk 15 d-3 mo) of healthy lactating women were investigated in terms of the high protein dietary pattern. Publication biases were evaluated by Egger's test. RESULTS According to the percentage in total fat of colostrum, transitional milk, and mature milk (% wt/wt), respectively, the results showed that PUFA (25.72%, 24.92%, and 22.69%), AA (0.85%, 0.76%, and 0.59%), DHA (0.53%, 0.47%, and 0.39%), EPA (0.15%, 0.10%, and 0.10%), and MUFA (37.39%, 37.21%, and 36.14%) contents in breast milk decreased with lactation, while another two PUFA forms, LA (17.47%, 17.82%, and 17.48%), and ALA (1.09%, 1.39%, and 1.24%) arrived at a peak in the transitional milk and then decreased in the mature milk, SFA (37.46%, 38.64%, and 40.52%), and lauric acid contents (2.78%, 4.91%, and 4.97%) increased with the lactation stages. CONCLUSION These findings could shed light on the dynamic change progress of major FA metabolism, potentially enhancing the knowledge of lactation biology, and improving infant feeding practices to meet their needs.

Abstract
OBJECTIVE Fortification of human milk (HM) with either human milk-derived fortifier (HMDF) or cow milk-derived fortifier (CMDF) is important in preterm infants. The objective is to compare the incidence of hypoglycemia, and biochemical values in infants less than 1,250 g at birth fed HMDF versus CMDF. STUDY DESIGN It is a retrospective cohort study on infants less than 1,250 g at birth who were fed with HMDF or CMDF. Hypoglycemia was defined as blood glucose (BG) level equal to or less than 60 mg/dL within 72 hours of full enteral feeds when off total parenteral nutrition and intravenous fluids. RESULTS Ninety infants were enrolled (HMDF = 61, CMDF = 29). HMDF group had a higher rate of hypoglycemia (46 vs. 24%; p = 0.048) after achievement of full enteral feeding. The median minimum BG was lower (61 vs. 71; p ≤ 0.01), while blood urea nitrogen (12 vs. 6; p ≤ 0.01) and albumin (3.1 vs. 2.7; p ≤ 0.01) were higher in HMDF group compared with CMDF. CONCLUSION At full enteral feedings in infants less than 1,250 g at birth, an HMDF diet may predispose to hypoglycemia needing intervention. Close monitoring of BG levels once off parenteral nutrition is recommended. KEY POINTS · Exclusive human milk (EHM) feeding results in better nutritional indices.. · EHM feeding at higher calorie/ounce improves growth.. · Blood glucose needs to be monitored when off TPN during EHM feeding..

Abstract
OBJECTIVES The impact of exclusive human milk diet (EHMD) on postnatal growth remains controversial. This study aims to investigate the association between EHMD and short-term growth. METHODS This multicenter retrospective study aims to compare growth between the EHMD and non-EHMD groups among infants <32 weeks of gestation. Primary outcomes include weight, length, and head circumference growth trajectories between birth and 34 weeks postmenstrual age. Sensitivity and subgroup analyses were performed. RESULTS An EHMD was independently associated with poorer length growth, especially in infants born at ≥28 weeks' gestation or those exposed to hypertensive disorders of pregnancy. While initiating fortification at <26 kcal/oz on an EHMD showed inferior growth, initiating fortification at ≥26 kcal/oz was associated with improved weight growth, and similar length and head circumference growth when compared to the non-EHMD group. CONCLUSIONS An EHMD with initial fortification at ≥26 kcal/oz may be implemented to avoid bovine milk exposure while sustaining comparable growth.

Abstract
In humans, the interindividual variability of clinical outcome following exposure to a microorganism is immense, ranging from silent infection to life-threatening disease. Age-specific immune responses partially account for the high incidence of infection during the first 28 days of life and the related high mortality at population level. However, the occurrence of life-threatening disease in individual newborns remains unexplained. By contrast, inborn errors of immunity and their immune phenocopies are increasingly being discovered in children and adults with life-threatening viral, bacterial, mycobacterial and fungal infections. There is a need for convergence between the fields of neonatal immunology, with its in-depth population-wide characterization of newborn-specific immune responses, and clinical immunology, with its investigations of infections in patients at the cellular and molecular levels, to facilitate identification of the mechanisms of susceptibility to infection in individual newborns and the design of novel preventive and therapeutic strategies.

Abstract
Mother's own milk (MOM) is known to decrease complications in preterm infants and when unavailable, it is recommended that preterm very low-birth weight infants be fed donor human milk (DHM). Due to the pasteurization, processing, and lactation stage of donors, DHM does not contain the same nutritional, immunologic, and microbial components as MOM. This review summarizes the differences between MOM and DHM, the potential effects on health outcomes, and the clinical implications of these differences. Finally, implications for research and clinical practice are discussed.

Abstract
OBJECTIVES To compare the duration required to regain birth weight following early fortification of human milk vs. late fortification among preterm infants. METHODS This randomized controlled trial included hemodynamically stable 120 preterm infants (≤32 wk of gestation). The intervention and comparator groups received standard fortification with human milk fortifier when enteral feeds reached 30 ml/kg/d (early fortification) and 80 ml/kg/d (late fortification) respectively. Neonates in both the groups received feed increments as per standard NICU protocol. Anthropometric measurements (weight, length, and head circumference) at birth and during postnatal follow-up were done following standard precautions and plotted on the sex-specific Fenton growth charts. Primary outcome was the mean duration required to regain birth weight. Secondary outcomes included weight gain velocity, linear growth, increase in head circumference and occurrence of sepsis, feed intolerance and necrotizing enterocolitis. RESULTS Preterm neonates who received early fortification regained birth weight earlier compared to those in the late fortification group (10.13 ± 2.90 vs. 11.26 ± 3.06, p <0.05). The weight gain velocity, linear growth and increase in head circumference were better in the early fortification group. There was no increased risk of culture proven sepsis, feed intolerance and necrotizing enterocolitis in the early fortification group compared to late fortification. CONCLUSIONS Standard fortification with human milk fortifier when enteral feeds reach 30 ml/kg/d helps preterm neonates regain birth weight earlier. Early fortification is well tolerated and safe for the population studied.

Abstract
Background: Implementation of exclusive human milk (EHM) feeding defined as mother's own milk or donor human milk fortified with human milk-derived fortifiers can place an economic burden on institutions. Methods: Retrospective study of very low birth weight (VLBW) infants before and after the implementation of EHM feedings. Neonatal demographics and clinical outcomes including necrotizing enterocolitis, severe retinopathy of prematurity, bronchopulmonary dysplasia, late-onset sepsis, days on parenteral nutrition (PN), and length-of-stay were collected. The net cost to the institution was estimated using published data. Results: Sixty-four infants in the pre-EHM period and 57 infants in the post-EHM period were enrolled. Net product acquisition cost in 2020 and 2021 was $884,823. The EHM feeding guideline led to a reduction in the mean length of stay and mean days of PN use by 6.3 and 6.8 days per infant, respectively. This led to a cost saving of $1,813,444 ($31,815 per infant). No significant difference in incidence of short-term morbidities was observed. Combining the cost avoidance from clinical outcomes, the estimated financial impact over 2 years excluding insurance reimbursement was an estimated $ 913,840 ($16,032 per infant). Conclusion: Implementation of EHM-based feeding in VLBW infants is a cost-effective option for neonatal intensive care units that can result in reduced length of stay and days on PN without adversely impacting short-term morbidities.

Malnutrition in Spinal Muscular Atrophy Type I: Case Report of a Novel Nutritional Intervention With Improved Growth and Function While Receiving Parallel Gene Splicing Therapies. Pediatr Neurol 2024; 151:76-79. [PMID: 38118381 DOI: 10.1016/j.pediatrneurol.2023.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 08/04/2023] [Accepted: 08/05/2023] [Indexed: 12/22/2023]
Abstract
Children with spinal muscular atrophy (SMA) frequently experience feeding intolerance and diminished growth. Although splicing modulators to prevent symptoms are available worldwide, adequate nutrition to support growth, development, and improved quality of life remains essential. We present a case study of a one-year-old malnourished male with SMA type I who achieved improved growth and feeding tolerance with a human milk (HM)-derived nutrition intervention. Despite feeding with appropriately balanced semielemental formula, he remained severely malnourished after two months of hospitalization. Feeds were partially replaced with HM-based diet plus a HM-based fat modular. Feeding tolerance, fecal calprotectin levels, and z scores for weight and length improved while receiving the HM-based intervention. We hypothesize that the HM-based feeding reduced intestinal inflammation by diminishing pathogenic elements of his microbiome. Owing to their aberrant fatty acid metabolism, patients with SMA are uniquely positioned to benefit from HM-based nutrient acquisition even while receiving splicing modulators to stabilize the disease process.

Abstract
BACKGROUND A common neonatal intensive care unit (NICU) discharge feeding strategy for preterm infants with growth failure who are fed exclusively expressed human milk (EHM) has been to enrich mother's own milk with formula powder or supplement 2-3 feeds per day with formula. However, this strategy displaces human milk from the diet. Our NICU recently adopted the standard practice of adding commercial human milk fortifier (HMF) to human milk feedings after discharge. OBJECTIVES We aimed to compare breastfeeding rates and growth using the aforementioned 2 strategies. METHODS Preterm infants (<34 wk of gestation at birth) exclusively feeding EHM fortified with HMF at 2 weeks before discharge were included in this retrospective study. The HMF group (n = 92) continued fortifying with HMF at home, whereas the historical comparison group (n = 35) received our previous guidance to enrich or supplement using postdischarge formula. RESULTS Rates of human milk exclusivity after discharge decreased significantly less in the HMF group than those in the historical comparison group (to 83% compared with 39% at the first outpatient visit and 27% compared with 6%, respectively, at the second outpatient visit). Rates of any EHM feedings were also significantly higher in the HMF group. Fenton z-scores for weight, length, and head circumference were not significantly different between the groups. CONCLUSIONS Continuing EHM fortification with HMF after NICU discharge, rather than enriching or supplementing with postdischarge infant formula, increases rates of feeding EHM for ≥3 mo but does not affect growth.

Abstract
Necrotizing enterocolitis (NEC) is one of the diseases in neonates, with a high morbidity and mortality rate, especially in preterm infants. This review aimed to briefly introduce the latest epidemiology, susceptibility factors, and clinical diagnosis and presentation of NEC. We also organized new prevention strategies by risk factors according to different pathogeneses and then discussed new treatment methods based on Bell's staging and complications, and the classification of mild to high severity based on clinical and imaging manifestations. Such a generalization will help clinicians and researchers to gain a deeper understanding of the disease and to conduct more targeted classification, grading prevention, and exploration. We focused on prevention and treatment of the early and suspected stages of NEC, including the discovery of novel biomarkers and drugs to control disease progression. At the same time, we discussed its clinical application, future development, and shortcomings.

Abstract
It is well recognized that human milk is the optimal nutritive source for all infants, including those requiring intensive care. This statement reviews evidence supporting the importance of breastfeeding and human milk for infants, and why breastfeeding practices should be prioritized in the neonatal intensive care unit (NICU). It also reviews how to optimally feed infants based on their stability and maturity, and how to support mothers to establish and maintain milk production when their infants are unable to feed at the breast.

Abstract
Mother's own milk is recognized as the optimal feeding not only for term but also for preterm infants. In addition to risk reduction for sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity in the early infancy, feeding preterm infants with mother's own milk is also associated with a better neurodevelopmental outcome; lower rates of otitis media, gastroenteritis, and respiratory infections; and a reduced risk of cardiovascular disease, obesity, and diabetes later in life. Donor human milk is the best alternative if mother's own milk is not available or with short supply. There is growing evidence that the benefits of human milk are mediated by the human milk microbiota and by human milk oligosaccharides through their influence on the infant's gut microbiota. Unfortunately, although human milk contains beneficial bacteria, it may also contain pathogenic bacteria. The antimicrobial properties of human milk protect those infants fed with their own mother's raw milk. In donor human milk, however, the antimicrobial activity is diminished due to storage and in particular by pasteurization, hereby lowering the resistance against bacterial infections. Subsequently, microbiological screening of donor human milk might enhance its safety for preterm infants. Up to date, a consensus on recommendations for the microbiological testing of donor human milk is lacking. Existing local and national guidelines for the microbiological screening vary significantly in terms of timing and frequency of testing as well as their specific acceptance and discard criteria. We reviewed the literature about microbiological testing of donor human milk to provide evidence-based recommendations for donor human milk.

Abstract
Phages and lipids in human milk (HM) may benefit preterm infant health by preventing gastrointestinal pathobiont overgrowth and microbiome modulation. Lipid association may promote vertical transmission of phages to the infant. Despite this, interrelationships between lipids and phages are poorly characterized in preterm HM. Shotgun metagenomics and untargeted lipidomics of phage and lipid profiles from 99 preterm HM samples reveals that phages are abundant and prevalent from the first week and throughout the first 100 days of lactation. Phage-host richness of preterm HM increases longitudinally. Core phage communities characterized by Staphylococcus- and Propionibacterium-infecting phages are significantly correlated with long-chain fatty acid abundances over lactational age. We report here a phage-lipid interaction in preterm HM, highlighting the potential importance of phage carriage in preterm HM. These results reveal possible strategies for phage carriage in HM and their importance in early-life microbiota development.

Abstract
Introduction Premature infants (PIs) are at risk of suffering necrotizing enterocolitis (NEC), and infants consuming human milk (HM) show a lower incidence than infants receiving formula. The composition of HM has been studied in depth, but the lipid content of HM-derived small extracellular vesicles (HM sEVs) remains unexplored. Identifying these molecules and their biological effects has potential for the treatment of intestinal disorders in PIs and could contribute to the development of HM-based fortified formulas. Methods We isolated HM sEVs from HM samples and analyzed their oxylipin content using liquid chromatography coupled to mass spectrometry, which revealed the presence of anti-inflammatory oxylipins. We then examined the efficacy of a mixture of these oxylipins in combating inflammation and fibrosis, in vitro and in a murine model of inflammatory bowel disease (IBD). Results HM-related sEVs contained higher concentrations of oxylipins derived from docosahexaenoic acid, an omega-3 fatty acid. Three anti-inflammatory oxylipins, 14-HDHA, 17-HDHA, and 19,20-DiHDPA (ω3 OXLP), demonstrated similar efficacy to HM sEVs in preventing cell injury, inducing re-epithelialization, mitigating fibrosis, and modulating immune responses. Both ω3 OXLP and HM sEVs effectively reduced inflammation in IBD-model mice, preventing colon shortening, infiltration of inflammatory cells and tissue fibrosis. Discussion Incorporating this unique cocktail of oxylipins into fortified milk formulas might reduce the risk of NEC in PIs and also provide immunological and neurodevelopmental support.

Abstract
A broad range of allergic disorders and intolerance are associated with cow's milk protein in the infant diet. Allergy and intolerance to cow's milk proteins are commonly recognized in the healthy term infant, and the prevalence cow's milk protein intolerance (CMPI) varies widely but 5 challenge confirmed studies free from selection bias ranged from 1.9%-4.9%. These disorders are classified by the presence of IgE, non-IgE or T-cell-mediated signaling. Additionally, the severity of these adverse food reactions can range from mild gastrointestinal symptoms to severe sepsis-like episodes, as in the case of food protein-induced enterocolitis syndrome (FPIES). Food protein-induced intolerance in the healthy young infant lies in stark contrast to enterocolitis that typically occurs in the preterm neonate. Necrotizing enterocolitis (NEC) is a distinct progressive disease process, usually characterized by a high mortality rate, with a risk of death from 30% to 50%. While its exact etiology is unclear, its main triggers include formula (cow's milk protein), hypoxia, perfusion-related issues, and unregulated inflammation in the premature intestine. The distinction between NEC and cow's milk protein intolerance is difficult to discern in some cases. In the late preterm population, infants with colitis can have both NEC and cow's milk intolerance on the differential. In infants with multiple episodes of mild NEC, cow's milk protein intolerance may be the underlying diagnosis. In this review, we compare the pathophysiological characteristics, diagnosis and treatment of disorders of cow's milk protein intolerance with the entity of preterm NEC. This review highlights similarities in both entities and may inspire future cross-disciplinary research.

Abstract
Background In recent years, the number of neonatal surgeries has been on the rise despite the decline in the number of births, and we examined the actual trends and problems at Tottori University Hospital located in the Sanin region. Methods Medical records were retrospectively searched for patients who underwent major surgery during the neonatal period (within 30 days of age) at the Tottori University Hospital over the past 10 years (Jan. 2011 to Dec. 2020). Results Sixty-five cases were included. Early birth infants (< 37 gestational weeks) comprised 15 cases (23%) and low birth weight (< 2500 g) infants involved 27 cases (42%). In the latter half (2016-2020), early birth and low birth weight infants were significantly less than in the first half (2011-2015). The common diseases were anorectal malformation (14 cases), esophageal atresia (10), duodenal atresia (10), and diaphragmatic hernia (9). Prenatal diagnosis was obtained in 26 cases (40%), with high diagnostic rate obtained in duodenal atresia (100%), abdominal wall defect (100%), ileal atresia (75%), meconium peritonitis (67%), and diaphragmatic hernia (67%). Fifty-five cases (85%) were operated on within 7 days of age. Other major malformations were associated in 23 cases (35%). There were 6 deaths (9%), of which 3 cases were low birth weight infants with gastrointestinal perforation, 2 cases with severe chromosomal abnormalities (esophageal atresia, omphalocele), and 1 case with diaphragmatic hernia with severe pulmonary hypertension. Home medical care has been required with gastrostomy tube in 2 cases. Conclusion Neonatal surgery at Tottori University has been well performed as required with acceptable results along with the progression of other perinatal care. However, further investigation for improvements in premature delivery or organ hypoplasia may be required.

Abstract
BACKGROUND This study quantified the displacement of human milk by commercial human milk fortifiers (HMFs) and infant formulas. METHODS Commercial liquid HMFs and powder infant formulas were added to pasteurized pooled donor human milk in triplicate, stirred, and weighed. The difference in weight between unfortified and fortified human milk at 22, 24, 26, 27, 28, and 30 kcal/ounce was calculated. RESULTS The displacement of human milk by liquid HMFs and powder infant formulas and powder HMF was highly associated with energy density. A human milk-derived HMF displaced significantly more human milk when compared with bovine milk-derived HMFs at equivalent energy densities. Similarly, powder infant formulas displaced less human milk when compared with a powder HMF, and the addition of hydrolyzed powder infant formulas resulted in less human milk displacement when compared with nonhydrolyzed powder infant formulas. CONCLUSIONS The displacement of human milk by commercial liquid HMFs and infant formulas must be considered when selecting a fortifying strategy.

Abstract
Maturational changes in the gut start in utero and rapidly progress after birth, with some functions becoming fully developed several months or years post birth including the acquisition of a full gut microbiome, which is made up of trillions of bacteria of thousands of species. Many factors influence the normal development of the neonatal and infantile microbiome, resulting in dysbiosis, which is associated with various interventions used for neonatal morbidities and survival. Extremely low gestational age neonates (<28 weeks' gestation) frequently experience recurring arterial oxygen desaturations, or apneas, during the first few weeks of life. Apnea, or the cessation of breathing lasting 15-20 s or more, occurs due to immature respiratory control and is commonly associated with intermittent hypoxia (IH). Chronic IH induces oxygen radical diseases of the neonate, including necrotizing enterocolitis (NEC), the most common and devastating gastrointestinal disease in preterm infants. NEC is associated with an immature intestinal structure and function and involves dysbiosis of the gut microbiome, inflammation, and necrosis of the intestinal mucosal layer. This review describes the factors that influence the neonatal gut microbiome and dysbiosis, which predispose preterm infants to NEC. Current and future management and therapies, including the avoidance of dysbiosis, the use of a human milk diet, probiotics, prebiotics, synbiotics, restricted antibiotics, and fecal transplantation, for the prevention of NEC and the promotion of a healthy gut microbiome are also reviewed. Interventions directed at boosting endogenous and/or exogenous antioxidant supplementation may not only help with prevention, but may also lessen the severity or shorten the course of the disease.

Abstract
BACKGROUND Antibiotic overutilization in the neonatal intensive care unit (NICU) has many adverse effects, and necrotizing enterocolitis (NEC) is one of the most common indications for antibiotics in premature infants. Evidence for a preferred antibiotic regimen for NEC is lacking. This project aims to reduce piperacillin-tazobactam use and overall antibiotic duration in neonates with NEC through the implementation of an antibiotic stewardship pathway based on the modified Bell stage classification system. METHODS A multidisciplinary team consisting of neonatology, pharmacy, infectious disease, and surgery developed an antibiotic protocol for the management of NEC based on Bell stage. Recommendations included 48 h of ampicillin/gentamicin (AG) for stage I, 5-10 days of AG for stage II, the addition of metronidazole for stage IIIA, and 7-14 days of piperacillin-tazobactam (PT) for stage IIIB. We evaluated overall antibiotic and PT exposure, progression to surgical NEC, NEC recurrence, antibiotic resistance, bacteremia/fungemia, and mortality 1 year pre- and post-protocol implementation. RESULTS 27 patients pre-intervention and 44 post-intervention were analyzed. Antibiotic exposure was reduced from a median 119.19 to 80.65 days of therapy (DOT) per 1000 patient days (p = 0.11). PT exposure decreased after protocol implementation (median 68.78 vs. 7.97 DOT per 1000 patient days, p = 0.002). There were no significant differences in morbidity or mortality outcomes. CONCLUSIONS Antibiotic stewardship strategies can be implemented in the NICU without compromising outcomes in patients with NEC. Bell stage stratification appears to be an effective method for antibiotic selection. Further studies are needed in a larger population to optimize regimens and ensure safety. TYPE OF STUDY Retrospective comparative study. LEVEL OF EVIDENCE Level III.

Abstract
Newborn infants require adequate nutrition to achieve full potential growth and development. Early life nutrition and health impacts long-term outcomes through adulthood. Human milk is the optimal source of nutrition during the first 6 months of life. However, infants admitted to the neonatal intensive care unit (NICU) often have comorbidities that create more or different nutrition demands than healthy newborns. There are different strategies to meet the nutrition needs of sick newborns, including use of parenteral nutrition, human milk fortifiers (HMFs), and infant formulas. Multinutrient HMFs are frequently used to achieve the higher nutrition demands of preterm infants. They are available in various presentations, such as human milk- or cow milk-derived, liquid or powder, and acidified or nonacidified, each of which has different risks and benefits associated with its use. Infant formulas are available to meet a demand when mother's own milk or donor breast milk is not available or sufficient, and there are also specialty formulas for infants with certain diseases that present unique nutrition needs. This review is focused on the use of HMFs to support the unique nutrition requirements of preterm infants for healthy growth, as well as the indications for the use of formulas among infants in the NICU.

Abstract
Milk is often regarded as the gold standard for the nourishment of all mammalian offspring. The World Health Organization (WHO) recommends exclusive breastfeeding for the first 6 months of the life of the infant, followed by a slow introduction of complementary foods to the breastfeeding routine for a period of approximately 2 years, whenever this is possible ( Global Strategy for Infant and Young Child Feeding; WHO, 2003). One of the most abundant components in all mammals' milk, which is associated with important health benefits, is the oligosaccharides. The milk oligosaccharides (MOS) of humans and other mammals differ in terms of their concentration and diversity. Among those, goat milk contains more oligosaccharides (gMOS) than other domesticated dairy animals, as well as a greater range of structures. This review summarizes the biological functions of MOS found in both human and goat milk to identify the possible biological relevance of gMOS in human health and development. Based on the existing literature, seven biological functions of gMOS were identified, namely, MOS action as prebiotics, immune modulators, and pathogen traps; their modulation of intestinal cells; protective effect against necrotizing enterocolitis; improved brain development; and positive effects on stressor exposure. Overall, goat milk is a viable alternate supply of functional MOS that could be employed in a newborn formula.

Abstract
OBJECTIVES Enteral nutrition with unfortified human milk during the first 2 postnatal weeks often leads to cumulative protein and energy deficits among preterm infants. Fortified human milk administered soon after birth could increase fat-free mass (FFM) and improve growth in these infants. METHODS This was a masked, randomized trial. Starting on feeding day 2, extremely preterm infants 28 weeks or younger fed maternal or donor milk were randomized to receive either a diet fortified with a human-based product (intervention group) or a standard, unfortified diet (control group). This practice continued until the feeding day when a standard bovine-based fortifier was ordered. Caregivers were masked. The primary outcome was FFM-for-age z score at 36 weeks of postmenstrual age (PMA). RESULTS A total of 150 infants were randomized between 2020 and 2022. The mean birth weight was 795±250 g, and the median gestational age was 26 weeks. Eleven infants died during the observation period. The primary outcome was assessed in 105 infants (70%). FFM-for-age z scores did not differ between groups. Length gain velocities from birth to 36 weeks PMA were higher in the intervention group. Declines in head circumference-for-age z score from birth to 36 weeks' PMA were less pronounced in the intervention group. CONCLUSIONS In infants born extremely preterm, human milk diets fortified soon after birth do not increase FFM accretion at 36 weeks' PMA, but they may increase length gain velocity and reduce declines in head circumference-for-age z scores from birth to 36 weeks' PMA.

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
OBJECTIVE To improve our human milk practices by increasing early and sustained use of colostrum as oral immune therapy (OIT) in very low birthweight (VLBW) infants admitted at a level 3 neonatal intensive care unit. STUDY DESIGN Using the Institute for Healthcare Improvement's Model for Improvement, several interventions aimed at increasing early OIT administration were implemented. Four key drivers included: optimizing evidence-based OIT guidelines, personnel alignment and engagement, optimal electronic health record use for ordering practices, and timely lactation consultant involvement. The primary outcome measure was early OIT administration, whereas secondary outcome measures examined all OIT administration and human milk at discharge. Process measures included the percentage of staff members who were compliant with OIT protocol. RESULTS Early OIT administration increased from a baseline mean of 6% to 55% in the 12-month study period. Percentage of total (early and late) OIT administration to VLBW infants increased from a baseline of 21% to 85%. Average human milk at discharge for VLBW infants remained at 44%, without significant improvement. CONCLUSIONS A multidisciplinary quality improvement initiative led to significant improvement in OIT administration to infants at a level 3 neonatal intensive care unit.

Abstract
Beginning and achieving full enteral nutrition is a key step in the care of preterm infants, particularly very low birth weight (VLBW) infants. As is true for many organ system-specific complications of prematurity, the gastrointestinal tract must complete in utero development ex utero while concurrently serving a physiologic role reserved for after completion of full term development. The preterm gut must assume the placental function of the interface between a source of energy, precursors for anabolism, and micronutrients, and the developing infant-through digestion and absorption of milk, instead of directly from the mother via the uteroplacental interface. The benefits of enteral nourishment in preterm infants are counterbalanced by gastrointestinal complications of prematurity: dysmotility leading to difficulty establishing and advancing feeds, and the risk of necrotizing enterocolitis (NEC). Concern for these complications can prolong the need for parenteral nutrition with an associated increase in risk for central line-associated bloodstream infection (CLABSI) and parenteral nutrition (PN)-associated cholestasis or liver disease (PNALD). Thus, a daily issue facing neonatologists caring for preterm infants is how to optimally begin, advance, and reach full enteral nutrition sufficient to satisfy the nutrient, energy, and fluid requirements of VLBW infants while minimizing risk. In this perspective, we provide an overview of the approaches and supporting data for starting and advancing enteral feeds in preterm infants, particularly very low birth weight infants, and we discuss the significant gaps in knowledge that accompany current approaches. This framework recognizes the dilemmas of preterm feeding initiation and advancement and identifies areas of opportunity for further investigation.

Abstract
BACKGROUND Human milk-based fortifiers (HMBF) are more costly than bovine milk-based fortifiers (BMBF); but, the efficacy of human or bovine fortification for infants born <1250 g has yet to be fully elucidated. Our objective was to determine the effect of fortifier source on tertiary neonatal costs. METHODS Costs associated with tertiary neonatal care, including direct and indirect hospital expenditures, feed-related costs and physician billing were analysed retrospectively for participants of OptiMoM (NCT02137473), a blinded RCT comparing fortifier type for babies born <1250 g. A generalized linear model of cost according to fortifier type was created. RESULTS Mean [95% confidence interval] daily costs per patient, adjusted for birth gestation and weight, was significantly greater in the human than the BMBF group ($3,452 [$3,186 - $3,740] Canadian dollars (CAD) versus $2,451 [$2,257 - $2,662] CAD) respectively, p < 0.0001). CONCLUSION HMBF usage entails additional costs on NICU stay that should be considered with implementation.

Abstract
The infant gut microbiome is a crucial factor in health and development. In preterm infants, altered gut microbiome composition and function have been linked to serious neonatal complications such as necrotizing enterocolitis and sepsis, which can lead to long-term disability. Although many studies have described links between microbiome composition and disease risk, there is a need for biomarkers to identify infants at risk of these complications in practice. In this study, we obtained stool samples from preterm infant participants longitudinally during the first postnatal months, and measured pH and redox, as well as SCFA content and microbiome composition by 16S rRNA gene amplicon sequencing. These outcomes were compared to clinical data to better understand the role of pH and redox in infant gut microbiome development and overall health, and to assess the potential utility of pH and redox as biomarkers. We found that infants born earlier or exposed to antibiotics exhibited increased fecal pH, and that redox potential increased with postnatal age. These differences may be linked to changes in SCFA content, which was correlated with pH and increased with age. Microbiome composition was also related to birth weight, age, pH, and redox. Our findings suggest that pH and redox may serve as biomarkers of metabolic state in the preterm infant gut.

Abstract
Introduction: Mothers of preterm infants are at risk for inadequate milk production. Pumping logs are often used to both encourage lactation in the first week and track its efficacy. Our objectives were to determine whether mothers of preterm infants who keep pumping logs are demographically different from those who do not and to determine whether this practice affects the amount of mother's own milk (MOM) fed to their infants. We also aimed at determining whether there is a correlation between: (1) time to first breast milk expression, (2) cumulative frequency of expression in the first week, and (3) milk volume on day 7 with subsequent milk volumes and percent of infant diet consisting of MOM. Methods: Mothers of infants born ≤32 weeks and ≤1,500 g were enrolled within 48 hours of birth and encouraged to keep a pumping log. Data were collected on maternal characteristics, patterns of milk expression, and milk volumes on days 7, 14, 21, and 28 after delivery. Infant data were collected via chart review. Results: Mothers who kept pumping logs provided their own milk for a greater percentage of their infant's feeds at the time of achieving full feeds (p = 0.017). The total number of expressions in the first week was correlated with milk volume on day 21 (p = 0.016) and the provision of a higher percentage of MOM feeds at discharge (p = 0.03). Milk volume on day 7 correlated with volumes obtained at days 14, 21, and 28 (p < 0.001). Conclusions: Pumping logs may affect the availability of MOM for preterm infants. Frequency of pumping in the first week and milk volume on day 7 may impact long-term lactation success for these women.

Abstract
OBJECTIVE The study aimed to determine the association of surgical necrotizing enterocolitis (NEC) and its timing, with the development and timing of retinopathy of prematurity (ROP). STUDY DESIGN This was a secondary data analysis of 7,483 preterm infants from the Postnatal Growth and Retinopathy of Prematurity Study. Associations between infants with surgical NEC, early-onset surgical NEC (8-28 days), and late-onset surgical NEC (over 28 days) with ROP were evaluated by using multivariable logistic regression models, controlling for birth weight, gestational age, small for gestational age status, chronic lung disease, intraventricular hemorrhage, hydrocephalus, patent ductus arteriosus, and periventricular leukomalacia. RESULTS Three hundred fifty-six (4.8%) infants had surgical NEC, with 56% having early surgical NEC. Infants with surgical NEC had a higher risk of any ROP and severe ROP (adjusted odds ratio [OR]: 2.7; 95% CI: 1.9-3.7) and 2.5 (95% CI: 1.9-3.3), respectively; p < 0.001) compared with infants without surgical NEC. Infants with early surgical NEC were at the highest risk of developing ROP and severe ROP (adjusted OR: 3.1 [95% CI: 2.1-4.8], and 3.3 [95% CI: 2.3-4.7] respectively, p < 0.001). Infants with late surgical NEC were also at increased risk of developing ROP and severe ROP (adjusted OR: 2.1 [95% CI: 1.3-3.4], and 1.9 [95% CI: 1.3-2.8] respectively, p < 0.001) compared with infants without surgical NEC. CONCLUSION Infants with surgical NEC, especially early surgical NEC, are at higher risk of ROP and severe ROP. KEY POINTS · Infants with surgical NEC are at higher risk of ROP and severe ROP than those without surgical NEC.. · Increased ROP risk is seen in infants with both early- or later onset surgical NEC.. · Early-onset surgical NEC is associated with a higher ROP risk compared with later onset surgical NEC..

Abstract
OBJECTIVE Review of age of onset of necrotising enterocolitis (NEC) and focal intestinal perforation (FIP) in very preterm (≤32 weeks) and/or very low birthweight (VLBW, ≤1500 g) infants. DESIGN Preregistered review undertaken according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses in July 2021 and updated October 2021. DATA SOURCES MEDLINE/ PubMed, Embase, CINAHL and Cochrane Central Register of Controlled Trials. ELIGIBILITY Eligible studies reported age of onset of NEC and/or FIP in randomised controlled trials of >200 or observational studies of >500 infants. DATA EXTRACTION AND SYNTHESIS Titles/abstracts were screened; eligible articles underwent data extraction. Age of onset as day of life (DOL) and/or corrected gestational age (CGA) were extracted alongside study information, such as NEC definition, included population, intervention, location and dates studied. Weighted means were used to compare onset by birth gestation, study type, NEC definition, trial intervention, location and dates studied. Comparison was done by Mann-Whitney U test or one-way analysis of variance. RESULTS Of the 747 screened studies 188 were eligible. Removal of duplicates, studies without onset data and ineligible populations left 10 RCTs and 14 observational studies contributing 51 NEC cohorts; 49 reported onset DOL and 14 CGA. 2984 cases of NEC had average DOL onset of 16.7 (15.5 in RCTs, 16.9 in observational studies), and CGA onset of 30.1 weeks. Gestation did not impact DOL onset. No other demographic feature impacted NEC onset. Few studies included data on FIP. CONCLUSIONS Average onset of NEC in exclusively very preterm/very low birthweight infants is in the third week of life and unlike in cohorts including more mature or heavier infants is not impacted by birth gestation.

Abstract
Necrotizing enterocolitis (NEC) is the leading cause of morbidity and mortality in preterm infants. NEC is multifactorial and the result of a complex interaction of feeding, dysbiosis, and exaggerated inflammatory response. Feeding practices in the neonatal intensive care units (NICUs) can vary among institutions and have significant impact on the vulnerable gastointestinal tract of preterm infants. . These practices encompass factors such as the type of feeding and fortification, duration of feeding, and rate of advancement, among others. The purpose of this article is to review the data on some of the most common feeding practices in the NICU and their impact on the development of NEC in preterm infants. Data on the human milk bioactive component glycosaminoglycans, specifically hyaluronan, will also be discussed in the context of postnatal intestinal development and NEC prevention.

Abstract
Maternal breast milk is the penultimate nutritional source for term and preterm neonates. Its composition is highly complex and includes multiple factors that enhance the development of nearly every neonatal organ system leading to both short- and long-term health benefits. Intensive research is focused on identifying breast milk components that enhance infant health. However, this research is complicated by the significant impact of maternal factors and the processing of pumped breast milk on bioactive ingredients. Optimizing enteral nutrition is particularly important for preterm neonates who miss the transplacental acquisition of nutrients in the third trimester of pregnancy and are at risk for illnesses associated with gut barrier dysfunction, including sepsis and necrotizing enterocolitis. In this review, we will discuss the health benefits of breast milk and its bioactive components.

Abstract
The intestinal microbiota is a diverse and complex microecosystem that lives and thrives within the human body. The microbiota stabilizes by the age of three. This microecosystem plays a crucial role in human health, particularly in the early years of life. Dysbiosis has been linked to the development of various allergic diseases with potential long-term implications. Next-generation sequencing methods have established that allergic diseases are associated with dysbiosis. These methods can help to improve the knowledge of the relationship between dysbiosis and allergic diseases. The aim of this review paper is to synthesize the current understanding on the development of the intestinal microbiota in children, the long-term impact on health, and the relationship between dysbiosis and allergic diseases. Furthermore, we examine the connection between the microbiome and specific allergies such as atopic dermatitis, asthma, and food allergies, and which mechanisms could determine the induction of these diseases. Furthermore, we will review how factors such as mode of delivery, antibiotic use, breastfeeding, and the environment influence the development of the intestinal flora, as well as review various interventions for the prevention and treatment of gut microbiota-related allergies.

BMC Pediatr 2023; 23:237. [PMID: 37173652 PMCID: PMC10176849 DOI: 10.1186/s12887-023-04047-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 04/29/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND Human milk-based human milk fortifier (HMB-HMF) makes it possible to provide an exclusive human milk diet (EHMD) to very low birth weight (VLBW) infants in neonatal intensive care units (NICUs). Before the introduction of HMB-HMF in 2006, NICUs relied on bovine milk-based human milk fortifiers (BMB-HMFs) when mother's own milk (MOM) or pasteurized donor human milk (PDHM) could not provide adequate nutrition. Despite evidence supporting the clinical benefits of an EHMD (such as reducing the frequency of morbidities), barriers prevent its widespread adoption, including limited health economics and outcomes data, cost concerns, and lack of standardized feeding guidelines. METHODS Nine experts from seven institutions gathered for a virtual roundtable discussion in October 2020 to discuss the benefits and challenges to implementing an EHMD program in the NICU environment. Each center provided a review of the process of starting their program and also presented data on various neonatal and financial metrics associated with the program. Data gathered were either from their own Vermont Oxford Network outcomes or an institutional clinical database. As each center utilizes their EHMD program in slightly different populations and over different time periods, data presented was center-specific. After all presentations, the experts discussed issues within the field of neonatology that need to be addressed with regards to the utilization of an EHMD in the NICU population. RESULTS Implementation of an EHMD program faces many barriers, no matter the NICU size, patient population or geographic location. Successful implementation requires a team approach (including finance and IT support) with a NICU champion. Having pre-specified target populations as well as data tracking is also helpful. Real-world experiences of NICUs with established EHMD programs show reductions in comorbidities, regardless of the institution's size or level of care. EHMD programs also proved to be cost effective. For the NICUs that had necrotizing enterocolitis (NEC) data available, EHMD programs resulted in either a decrease or change in total (medical + surgical) NEC rate and reductions in surgical NEC. Institutions that provided cost and complications data all reported a substantial cost avoidance after EHMD implementation, ranging between $515,113 and $3,369,515 annually per institution. CONCLUSIONS The data provided support the initiation of EHMD programs in NICUs for very preterm infants, but there are still methodologic issues to be addressed so that guidelines can be created and all NICUs, regardless of size, can provide standardized care that benefits VLBW infants.

Abstract
Objectives: Impact of the proportion of human milk (HM) in mixed feeding on necrotizing enterocolitis (NEC) remains unknown. This study explores the influence of different proportions of HM on the risk of NEC. Materials and Methods: A retrospective cohort study was performed in infants with very low birth weight (VLBW). A spline smoothing curve was used to evaluate the dose-dependent association between HM and the risk of NEC. Univariate and multivariate analyses were performed to detect the association between the proportion of HM and NEC. Results: Twenty-four infants developed NEC, with 4 (1.9%) in the high HM group, 18 (28.1%) in the low HM group, and 2 (8.0%) in the exclusive formula group (p < 0.001). After adjusting for the relevant confounders, low HM (proportion of HM ≤54%) (OR 33.526, 95% confidential interval [CI] 7.183-156.475, p < 0.001) and exclusive formula feeding (OR 8.493, 95% CI 1.107-65.187, p = 0.040) significantly increased the incidence of NEC, compared with the high HM feeding (proportion of HM >54%). Similarly, low HM was independently associated with an increased risk of feeding intolerance compared with high HM feeding (OR 4.383, 95% CI 2.243-8.564, p < 0.001). Conclusion: A low ratio of HM (≤54%) significantly increased the risk of intestinal complications in VLBW infants. Mixed feeding should relate to the proportion of HM in premature infants.

Abstract
OBJECTIVE To investigate differences in hypoglycemia and extended feed prescriptions among premature infants provided bovine-derived human milk fortifiers (Bov-fort) with mother's milk or formula vs human milk-derived human milk fortifiers (HM-fort) with mother's milk or donor human milk. STUDY DESIGN This was a retrospective chart review (n = 98). Infants receiving HM-fort were matched with infants receiving Bov-fort. Blood glucose values and feed orders were retrieved from the electronic medical record. RESULTS Prevalence of ever having blood glucose <60 mg/dL was 39.1% in the HM-fort group vs. 23.9% in the Bov-fort group (p = 0.09). Blood glucose ≤45 mg/dL occurred in 17.4% of HM-fort vs 4.3% in Bov-fort (p = 0.07). Feeds were extended for any reason in 55% of HM-fort vs. 20% of Bov-fort (p < 0.01). Feed extension due to hypoglycemia occurred in 24% of HM-fort vs. 0% of Bov-fort (p < 0.01). CONCLUSION Predominately HM-based feeds are associated with feed extension due to hypoglycemia. Prospective research is warranted to elucidate underlying mechanisms.

Abstract
Objective: To compare growth velocity (GV) in preterm infants fed mother's own milk (MOM) fortified with human milk-based fortifier (HMBF) to those who received donor human milk (DHM) fortified with HMBF. Study Design: A retrospective study of preterm infants with birth weight <1,250 g receiving an exclusive human milk diet. Maternal and infant charts were reviewed for feeding, growth, and short-term neonatal morbidities. Results: On regression analysis, after adjusting (gestational age, multiple births, antenatal steroids, and small for gestational age), no significant difference was observed between the two groups in GV from birth to 32 weeks postmenstrual age (β-coefficient 0.83, 95% confidence interval [CI]: -0.47 to 2.14, p = 0.21), GV from the day of regaining of birth weight to discharge (β-coefficient -0.015, 95% CI: -1.08 to 1.05, p = 0.98). The rate of Grade 3 and 4 intraventricular hemorrhage was significantly higher in the DHM group (19.6% compared to 5.5% in MOM, p = 0.03). Conclusion: At our institution, there was no difference in GV of preterm infants fed HMBF-fortified MOM versus HMBF-fortified DBM.
