Abstract
Objective
Small for gestational age (SGA) preterm infants (PT) are at greatest risk for growth failure. Our objective was to assess the impact of an exclusive human milk diet (HUM) on growth velocities and neonatal morbidities from birth to discharge in a SGA population.
Study design
Multicenter, retrospective cohort study, subgroup analysis of SGA PT comparing a cow’s milk diet (CMD) with HUM diet.
Results
At birth 420 PT were classified as SGA (197 CMD group, 223 HUM group). Demographics and anthropometric measurements were similar. HUM group PT showed improvement in length Z score at discharge (p = 0.024) and reduction in necrotizing enterocolitis (NEC) (p = 0.004).
Conclusion
SGA PT fed a HUM diet had significantly decreased incidence of NEC, surgical NEC, and late-onset sepsis. Due to concerns about growth in a HUM diet, it is reassuring SGA infants fed the HUM diet had similar growth to CMD diet with trends toward improvement

Abstract
Objective
An increasingly common practice is to feed preterm infants a base diet comprising only human milk (HM), usually fortified with a cow's milk (CM)-derived fortifier (CMDF). We evaluated the safety of CMDF in a diet of 100% mother's own milk (MOM) against a HM-derived fortifier (HMDF). To date, this has received little research attention.
Study Design
We reanalyzed a 12-center randomized trial, originally comparing exclusive HM feeding, including MOM, donor milk (DM), and HMDF, versus a CM exposed group fed MOM, preterm formula (PTF), and CMDF1. However, for the current study, we performed a subgroup analysis (n = 114) selecting only infants receiving 100% MOM base diet plus fortification, and fed no DM or PTF. This allowed for an isolated comparison of fortifier type: CMDF versus HMDF to evaluate the primary outcomes: necrotizing enterocolitis (NEC) and a severe morbidity index of NEC surgery or death; and several secondary outcomes.
Results
CMDF and HMDF groups had similar baseline characteristics. CMDF was associated with higher risk of NEC; relative risk (RR) 4.2 (p = 0.038), NEC surgery or death (RR 5.1, p = 0.014); and reduced head circumference gain (p = 0.04).
Conclusions
In neonates fed, as currently recommended with a MOM-based diet, the safety of CMDF when compared to HMDF has been little researched. We conclude that available evidence points to an increase in adverse outcomes with CMDF, including NEC and severe morbidity comprising NEC surgery or death.

Abstract
Objective
Substantial losses of nutrients may occur during tube (gavage) feeding of fortified human milk. Our objective was to compare the losses of key macronutrients and minerals based on method of fortification and gavage feeding method.
Methods
We used clinically available gavage feeding systems and measured pre- and post-feeding (end-point) nutrient content of calcium (Ca), phosphorus (Phos), protein, and fat. Comparisons were made between continuous, gravity bolus, and 30-minute infusion pump feeding systems, as well as human milk fortified with donor human milk-based and bovine milk-based human milk fortifier using an in vitro model.
Results
Feeding method was significantly associated with fat and Ca losses, with increased losses in continuous feeds. Fat losses in continuous feeds were substantial, with 40 ± 3 % of initial fat lost during the feeding process. After correction for feeding method, human milk fortified with donor milk-based fortifier was associated with significantly less loss of Ca (8 ± 4% vs. 28 ± 4%, p< 0.001), Phos (3 ± 4% vs. 24 ± 4%, p < 0.001), and fat (17 ± 2% vs. 25 ± 2%, p = 0.001) than human milk fortified with a bovine milk-based fortifier (Mean ± SEM).

Abstract
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.
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.
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.
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
Objective:
To determine whether weight gain velocity (g/kg/day) 30 days after the initiation of feeds after cardiac surgery and other clinical outcomes improve in infants with single ventricle physiology fed an exclusive human milk diet compared with a mixed human and bovine diet.
Study design:
In this multicenter, randomized, single blinded, controlled trial, term neonates 7 days of age or younger with single ventricle physiology and anticipated cardiac surgical palliation within 30 days of birth were enrolled at 10 US centers. Both groups received human milk if fed preoperatively. During the 30 days after feeds were started postoperatively, infants in the intervention group received human milk fortified once enteral intake reached 60 mL/kg/day with a human milk-based fortifier designed for term neonates. The control group received standard fortification with formula once enteral intake reached 100 mL/kg/day. Perioperative feeding and parenteral nutrition study algorithms were followed.
Results:
We enrolled 107 neonates (exclusive human milk = 55, control = 52). Baseline demographics and characteristics were similar between the groups. The median weight gain velocity at study completion was higher in exclusive human milk vs control group (12 g/day [IQR, 5-18 g/day] vs 8 g/day [IQR, 0.4-14 g/day], respectively; P = .03). Other growth measures were similar between groups. Necrotizing enterocolitis of all Bell stages was higher in the control group (15.4 % vs 3.6%, respectively; P = .04). The incidence of other major morbidities, surgical complications, length of hospital stay, and hospital mortality were similar between the groups.
Conclusions:
Neonates with single ventricle physiology have improved short-term growth and decreased risk of NEC when receiving an exclusive human milk diet after stage 1 surgical palliation.

Magro, S; Cini, A; Sammut, R
Abstract
Objective: The purpose of this review was to determine whether breast milk fortified with human-based fortifiers decreases the incidence of necrotising enterocolitis in preterm infants.
Design: A search was carried out ending July 2021. Academic Search Complete, Cochrane Central Register of Control Trials, Cochrane Database of Systematic Reviews, PubMed, CINAHL plus with full text, Environmental Complete (EBSCO), JAMA Network, MEDLINE, BioMed Central and SAGE Journals and Google Scholar were searched. Keywords included: preterm, infants, breast milk, formula milk and necrotising enterocolitis.
Findings: Sixteen of the 1316 retrieved papers were included. Human milk, whether mother’s own or donor milk, and human milk fortifiers decrease the risk of necrotising enterocolitis, compared to formula milk and non-human fortifiers.
Conclusions: Standardised guidelines should be developed and applied in neonatal units, promoting the use of human milk with human milk fortifiers with the aim of reducing the risk of necrotising enterocolitis in preterm infants.

Abstract
Objectives: Small infants require adequate enteral nutrition to achieve continuous growth. Therefore, breast milk should be supplemented with fortifier. In addition to the cost-efficient fortifiers produced from bovine milk, an expensive fortifier derived from human milk has been available. We compared, whether preterm infants benefit from human fortifier supplementation and whether the higher purchase costs are economically viable for hospitals.
Methods: Preterm infants of <32+0 gestational week and <1000 g birth weight, were enrolled. The newborns were nourished with human milk. Supplementation with human fortifier or bovine fortifier was initiated once oral milk intake reached 100 mL/kg BW/d. Standardized documentation of body weight, respiratory situation, Intraventricular Hemorrhage (IVH), Periventricular Leukomalacia (PVL), Necrotizing Enterocolitis (NEC) and Retinopathy of Prematurity (ROP) and duration of the in-hospital stay was undertaken at day of life 7, 14, 21, 35 and 42. For each individual the revenue was calculated.
Results: Between 01/2019 and 12/2020, 23 children were enrolled. 10 preterms received human and 13 bovine fortifier. 2 infants developed BPD and one required ligature for a Patent Ductus Arteriosus Botalli (PDA) in the children who were supplemented with human milk-based fortifier. Three children in the group fed the bovine fortifier developed BPD, PVL was documented in one, ROP in 2, higher-grade NEC in one and ductus ligature was required by two children. Stool-calprotectin values measured on study days 35 and 42 were significant lower in infants given human fortifier. Nevertheless, the in-hospital stay was shorter in the human fortifier group (median of 75.5 days) than in the bovine fortifier (median of 80 days) group.
Total revenue gain was +39854.20 € (+5958.20 € per patient) in patients fed the human fortifier versus +20573.42 €(-346.00 € per patient) in individuals who received bovine fortifier. The costs for human fortifier supplementation were in total € 41005.00. Bovine fortifier was less expensive (total cost: € 250.00).
Conclusion: Fortifiers produced from human milk entail higher therapeutic costs but are offset by shorter in-hospital stays and fewer morbidities among preterm infants. Preterm infants tolerate human milk-based fortifiers significantly better than bovine-based fortifiers.

Abstract
Background
Our level III neonatal intensive care unit (NICU) implemented the use of an exclusive human milk diet (EHD) and sought to determine its effect on the severe co-morbidities of preterm infants as well as the potential cost-savings due to the anticipated reduction in these co-morbidities.
Methods
A retrospective cohort study was completed to determine if an EHD statistically decreased the rate of co-morbidities including length of stay (LOS), days on total parental nutrition (TPN), rates of late onset sepsis, necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), and severe retinopathy of prematurity (ROP).
Results
An EHD significantly decreased the odds of severe ROP (adjusted odds-ratio (aOR)=0.349; 95%CI [0.156, 0.739]; p=0.008) and late onset sepsis (aOR=0.323; 95%CI [0.123, 0.768]; p=0.014). Analysis of cost-effectiveness of an EHD relative to a BSD based on the incremental costs of these co-morbidities determined the net loss in direct hospital costs per patient were estimated to be $420 in 2016 US dollars; however, given the long-term health-care costs and non-pecuniary damages from the co-morbidities of severe ROP and sepsis this net loss appears negligible.
Conclusion
This study found that an EHD significantly decreased the odds of severe ROP and late onset sepsis; though not significant, there was a positive trend in decreasing cases of medical NEC; our surgical NEC rates dropped to 0. The benefits of human milk are vital, and the costs are nominal.

Abstract
Objective
To conduct a systematic review and meta-analysis of the efficacy and safety of fortification of human milk with human milk-based fortifier versus cow’s milk-based fortifier for use in preterm and/or very low birthweight infants.
Design
Randomised or quasi-randomised controlled trials comparing the effect of human milk fortification with human milk-based milk fortifier versus cow’s milk-based fortifier in infants born <34 weeks’ gestation and/or with birth weight <1500 g were identified by searching databases, clinical trial registries and reference lists until 5 November 2019. Two authors independently extracted data and assessed evidence quality. Meta-analyses were conducted using fixed or random effects models, as appropriate.
Main outcome measures
Necrotising enterocolitis (Bell’s stage II or higher) and late-onset sepsis.
Results
Of 863 unique records identified, 16 full-text trials were screened and 2 trials involving 334 infants were included. Primary outcome data were available for 332 infants. Use of human milk-based fortifier compared with cow’s milk-based fortifier reduced the risk of necrotising enterocolitis (risk ratio 0.47, 95% CI 0.22 to 0.98). There was no clear evidence of an effect on late-onset sepsis or any other outcomes. The quality of evidence was low to very low due to imprecision and lack of blinding in one study.
Conclusions:
Findings suggest that there is a reduction in the incidence of necrotising enterocolitis with human milk-based fortifiers compared with cow’s milk-based fortifiers. The overall quality of evidence is low. Further appropriately powered trials are required before this intervention can be routinely recommended for preterm infants.

Abstract
Recently we published a meta-analyses of morbidity seen with the use of cow’s milk derived fortifier (CMDF) rather than human milk derived fortifier (HMDF) in very low birthweight (VLBW) infants. Here, we further analyse these data to estimate the annual population risk of CMDF-related major morbidity in the United States and Canada. The outcome used was a mortality/morbidity index which was positive if the infants had one or more of death, necrotising enterocolitis, sepsis retinopathy of prematurity or bronchopulmonary dysplasia. Using the risk difference (RD) between the CMDF and HMDF groups we estimated, provisionally, that 4150 additional VLBW infants in the United States and Canada each year, or an additional infant approximately every 2 hours, may be expected to develop a positive mortality/morbidity index in relation to being fed CMDF – over and above the number of infants with a positive index if fed HMDF. We provide an in-depth discussion of the limitations of our estimate. This analysis provides preliminary evidence of the magnitude of population risk of major neonatal morbidity with use of CMDF versus HMDF in VLBW infants in current practice.
Incidence of spontaneous intestinal perforations exceeds necrotizing enterocolitis in extremely low birth weight infants fed an exclusive human milk-based diet: A single center experience

Abstract
Background
Spontaneous intestinal perforation (SIP) and necrotizing enterocolitis (NEC) are complications of extremely low birth weight (ELBW, ≤1000 g) infants. ELBW infants at Texas Children's Hospital receive an exclusive human milk-based diet, which has been associated with a reduction of NEC.
Objectives
1) Assess incidence of SIP and NEC (Stage II or greater) in ELBW infants receiving 100% human milk-based diet, 2) Describe mortality rates of ELBW infants with SIP and NEC.
Methods
Prospective single-center observational cohort study of ELBW infants born between 2010 and 2014 with SIP or NEC (exclusion: congenital anomalies and death within 48 h).
Results
Of 379 ELBW infants, 345 were eligible. Of these, 28 (8.1%) had SIP and 8 (2.3%) had NEC (medical n = 1, surgical n = 7). SIP infant mortality was 32% (n = 9) compared to 63% (n = 5) for NEC patients. Of SIP infants with PD (n = 25), 52% required subsequent exploratory laparotomy (LAP). Of NEC infants with peritoneal drainage (PD) (n = 2), both required subsequent LAP.
Conclusion
Using an exclusive human milk-based diet, the incidence of SIP exceeds NEC in ELBW infants at our institution. This shows a changing trend in the incidence of these two diagnoses in the era of human milk, as NEC had previously been more prevalent in ELBW infants. More than half of infants who initially received PD later required LAP. There were no differences in survival outcomes in both SIP and NEC groups based on surgical management.
