BACKGROUND: Mother's own milk is the first choice for feeding preterm infants, but when not available, pasteurized human donor milk (PDM) is often used. Infants fed PDM have difficulties maintaining appropriate growth velocities. To assess the most basic elements of nutrition, we tested the hypotheses that fatty acid and amino acid composition of PDM is highly variable and standard pooling practices attenuate variability; however, total nutrients may be limiting without supplementation due to late lactational stage of the milk...

Background: Holder pasteurization (HP) destroys multiple bioactive factors in donor human milk (DM), and UV-C irradiation (UVC) is potentially a gentler method for pasteurizing DM for preterm infants.Objective: We investigated whether UVC-treated DM improves gut maturation and resistance toward bacterial infections relative to HP-treated DM.Methods: Bacteria, selected bioactive components, and markers of antioxidant capacity were measured in unpasteurized donor milk (UP), HP-treated milk, and UVC-treated milk (all from the same DM pool)...

Fucosyllactoses, including 2'-fucosyllactose (2'-FL) and 3-fucosyllactose (3-FL), are important oligosaccharides in human milk that are commonly used as nutritional additives in infant formula due to their biological functions, such as the promotion of bifidobacteria growth, inhibition of pathogen infection, and improvement of immune response. In this study, we developed a synthetic biology approach to promote the efficient biosynthesis of 2'-FL and 3-FL in engineered Escherichia coli. To boost the production of 2'-FL and 3-FL, multiple modular optimization strategies were applied in a plug-and-play manner...

BACKGROUND: Human milk oligosaccharides (HMOs) have important protective functions in human milk. A low-cost remote pasteurisation temperature-monitoring system has been designed using FoneAstra, a cell phone-based networked sensing system to monitor simulated flash heat pasteurisation. AIM: To compare the pasteurisation effect on HMOs of the FoneAstra FH method with the current Sterifeed Holder method used by human milk banks. METHODS: Donor human milk samples (n = 48) were obtained from a human milk bank and pasteurised using the two pasteurisation methods...

BACKGROUND: Premature infants have a high risk for dysbiosis of the gut microbiome. Mother's own milk (MOM) has been found to favorably alter gut microbiome composition in infants born at term. Evidence about the influence of feeding type on gut microbial colonization of preterm infants is limited. OBJECTIVE: The purpose of this study was to explore the effect of feeding types on gut microbial colonization of preterm infants in the neonatal intensive care unit. METHODS: Thirty-three stable preterm infants were recruited at birth and followed up for the first 30 days of life...

BACKGROUND: There are rising rates of multiple births worldwide with associated higher rates of complications and more hospital care, often due to prematurity. While there is strong evidence about the risks of not breastfeeding, rates of breastfeeding in women who have given birth to more than one infant are lower than with singleton births. Breastfeeding more than one infant can be more challenging because of difficulties associated with the birth or prematurity. The extra demands on the mother of frequent suckling, coordinating the needs of more than one infant or admission to the neonatal intensive care unit can lead to delayed initiation or early cessation...

Adequate nutrition is important for neurodevelopmental outcomes in preterm-born infants. In this review, we aim to summarize the current knowledge on nutritional interventions initiated during the hospital stay targeting brain and cognitive development benefits in preterm human infants. Studies can broadly be split in general dietary intervention studies and studies investigating specific nutrients or nutritional supplements. In general, mother's breast milk was reported to be better for preterm infants' neurodevelopment compared to infant formula...

A pasteurization temperature monitoring system has been designed using FoneAstra, a cellphone-based networked sensing system, to monitor simulated flash-heat (FH) pasteurization. This study compared the effect of the FoneAstra FH (F-FH) method with the Sterifeed Holder method currently used by human milk banks on human milk immune components (immunoglobulin A (IgA), lactoferrin activity, lysozyme activity, interleukin (IL)-8 and IL-10). Donor milk samples (N = 50) were obtained from a human milk bank, and pasteurized...

PURPOSE: Donor milk (DM) represents an important nutrition source for high-risk newborns. Holder pasteurization (HoP) is the most recommended procedure for DM treatment, providing a good compromise between microbiological safety and biological quality. HoP was previously shown to affect DM cytokines, growth factors and hormones levels, whilst no data concerning the possible effects of HoP on neurobiomarkers (NB) are available. Therefore, our study investigated whether the concentration in DM of a well-known NB involved in brain development/damage, namely S100B, changes due to HoP...

An important mechanism of nutritional "programming" induced by supplementation with methyl donors during pregnancy is the alteration of mRNA abundance in the offspring. We investigated the effects of rumen-protected Met (RPM) on abundance of 17 genes in the 1-carbon, Met, and transsulfuration pathways in calf liver from cows fed the same basal diet without (control, CON) or with RPM at 0.08% of diet dry matter/d (MET) from -21 through +30 d around calving. Biopsies (n = 8 calves per diet) were harvested on d 4, 14, 28, and 50 of age...

The aim of human milk banks is to deliver safe and high quality donor human milk. Treatment of human milk has to destroy most microorganisms while preserving immunological and nutrient components, which is obtained when using low time low temperature pasteurization. However it destroys bile-simulated lipase, reduces lactoferrin, lysozyme, immunoglobulins, and bactericidal capacity of human milk. New methods are under investigation such as high temperature short time pasteurization, high pressure processing, or ultraviolet irradiation...

This article summarizes evidence regarding whether a donor human milk (DHM) and/or an exclusively human milk (EHM) diet decreases the incidence of necrotizing enterocolitis (NEC) and the dose of human milk (HM) necessary to reduce the risk of NEC in premature infants. Additional research regarding protection afforded by DHM and EHM is necessary as well as research elucidating the exact dose of HM necessary for NEC risk reduction. Research is also needed to determine whether there is a dose-dependent effect of DHM, a combination of mother's own milk and DHM, and an EHM diet on NEC incidence...

The immune system of preterm infants is immature, placing them at increased risk for serious immune-related complications. Human milk provides a variety of immune protective and immune maturation factors that are beneficial to the preterm infant's poorly developed immune system. The most studied immune components in human milk include antimicrobial proteins, maternal leukocytes, immunoglobulins, cytokines and chemokines, oligosaccharides, gangliosides, nucleotides, and long-chain polyunsaturated fatty acids...

The provision of donor human milk avoids the risks associated with early infant formula feeding only when maternal milk is unavailable. Donor human milk-banking services (DHMBS) should provide an effective clinical service that causes no harm to donors or recipients. This article aims to begin the process of defining the minimum acceptable standard required for safe donor human milk banking in the neonatal unit. An assessment process is established to consider the potential risks and benefits of milk banking to both recipients and donors...

Best practices translating the evidence for high-dose human milk (HM) feeding for preterm infants during neonatal intensive care unit (NICU) hospitalization have been described, but their implementation has been compromised. Although the rates of any HM feeding have increased over the last decade, efforts to help mothers maintain HM provision through to NICU discharge have remained problematic. Special emphasis should be placed on prioritizing the early lactation period of coming to volume so that mothers have sufficient HM volume to achieve their personal HM feeding goals...

BACKGROUND: Peer milk sharing, the noncommercial sharing of human milk from one parent or caretaker directly to another for the purposes of feeding a child, appears to be an increasing infant-feeding practice. Although the U.S. Food and Drug Administration has issued a warning against the practice, little is known about how people who share human milk handle and store milk and whether these practices are consistent with clinical safety protocols. Research aim: This study aimed to learn about the milk-handling practices of expressed human milk by milk-sharing donors and recipient caretakers...

BACKGROUND: Potential donors of human milk are screened for Ebola virus (EBOV) using standard questions, but testing for EBOV and Marburg virus (MARV) is not part of routine serological testing performed by milk banks. Research aim: This study tested the hypothesis that EBOV would be inactivated in donor human milk (DHM) by standard pasteurization techniques (Holder) used in all North American nonprofit milk banks. METHODS: Milk samples were obtained from a nonprofit milk bank...

Inducing lactation in the absence of pregnancy (nonpuerperal lactation) is not always successful and, in many cases, only partial breastfeeding is achieved. Different protocols have been described, but scientific evidence and research are lacking in this area. The authors describe the case of a woman with a history of a miscarriage, for whom the lactation induction process was so effective that she became a milk donor even before she received her adopted child. She had not previously used hormone treatment...

BACKGROUND: The initial acquisition and early development of the intestinal microbiome during infancy are important to human health across the lifespan. Mode of birth, antibiotic administration, environment of care, and nutrition have all been shown to play a role in the assembly of the intestinal microbiome during early life. For preterm infants, who are disproportionately at risk of inflammatory intestinal disease (i.e., necrotizing enterocolitis), a unique set of clinical factors influence the establishment of the microbiome...

In the 1960s/early 70s there was a widespread conviction in West Germany that mother's milk was no longer essential even for premature infants given the availability of improved industrial milk products. But today the superiority of human milk is again undisputed, and progress in neonatology has created a growing target group of extremely premature infants who show clear benefits from being fed with human milk, particularly regarding improved outcomes. Currently there is a revival of donor milk banks (FMB)...
