Human milk is the ideal source of nutrition for most infants, but significant gaps remain in our understanding of human milk biology. As part of addressing these gaps, the Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN) Project Working Groups 1-4 interrogated the state of knowledge regarding the infant-human milk-lactating parent triad. However, to optimize the impact of newly generated knowledge across all stages of human milk research, the need remained for a translational research framework specific to the field. Thus, with inspiration from the simplified environmental sciences framework of Kaufman and Curl, Working Group 5 of the BEGIN Project developed a translational framework for science in human lactation and infant feeding, which includes 5 nonlinear, interconnected translational stages, T1: Discovery; T2: Human health implications; T3: Clinical and public health implications; T4: Implementation; and T5: Impact. The framework is accompanied by 6 overarching principles: 1) Research spans the translational continuum in a nonlinear, nonhierarchical manner; 2) Projects engage interdisciplinary teams in continuous collaboration and cross talk; 3) Priorities and study designs incorporate a diverse range of contextual factors; 4) Research teams include community stakeholders from the outset through purposeful, ethical, and equitable engagement; 5) Research designs and conceptual models incorporate respectful care for the birthing parent and address implications for the lactating parent; 6) Research implications for real-world settings account for contextual factors surrounding the feeding of human milk, including exclusivity and mode of feeding. To demonstrate application of the presented translational research framework and its overarching principles, 6 case studies are included, each illustrating research gaps across all stages of the framework. Applying a translational framework approach to addressing gaps in the science of human milk feeding is an important step toward the aligned goals of optimizing infant feeding across diverse contexts as well as optimizing health for all.

BackgroundGlobally, almost 15 million infants are born prematurely each year, disproportionately affecting low and middle-income countries. In the absence of mother's milk, the World Health Organization recommends using donor human milk (DHM) due to its protective effect against necrotizing enterocolitis, a life-threatening intestinal disorder. The use of DHM is increasing globally, with many low and middle-income countries integrating donor milk banks into their public health strategies to reduce neonatal mortality, yet very little is known about the nutritional composition of DHM. Additional knowledge gaps include how DHM composition is influenced by milk banking practices, and whether preterm nutrient recommendations are achieved when DHM is used with commercially available fortifiers.MethodsWe designed a multi-site study with eight geographically diverse milk bank partners in high, middle, and low-income settings that will examine and compare a broad range of nutrients and bioactive factors in human milk from 600 approved milk bank donors around the world to create comprehensive, geographically diverse nutrient profiles for DHM. We will then simulate the random pooling of 2 to 10 donors to evaluate the impact of pooling as a potential strategy for milk banks to manage nutrient variability in DHM. Finally, we will evaluate whether commercially available fortifiers meet nutrient recommendations when used with DHM.DiscussionWe expect that results from this study will improve nutritional care globally for the growing number of preterm infants who receive donor human milk.

Donor human milk is recommended by the World Health Organization both for its advantageous nutritional and biological properties when mother's own milk is not available and for its recognized support for lactation and breastfeeding when used appropriately. An increasing number of human milk banks are being established around the world, especially in low- and middle- income countries, to facilitate the collection, processing and distribution of donor human milk. In contrast to other medical products of human origin, however, there are no minimum quality, safety and ethical standards for donor human milk and no coordinating global body to inform national policies. We present the key issues impeding progress in human milk banking, including the lack of clear definitions or registries of products; issues around regulation, quality and safety; and ethical concerns about commercialization and potential exploitation of women. Recognizing that progress in human milk banking is limited by a lack of comparable evidence, we recommend further research in this field to fill the knowledge gaps and provide evidence-based guidance. We also highlight the need for optimal support for mothers to provide their own breastmilk and establish breastfeeding as soon as and wherever possible after birth. Lorsque la mere est dans l'impossibilite d'allaiter, l'Organisation mondiale de la Sante recommande d'opter pour le lait humain provenant de donneuses, tant pour ses proprietes nutritionnelles et biologiques que pour la contribution averee qu'il apporte a la lactation et a l'allaitement quand il est utilise a bon escient. Un nombre croissant de banques de lait humain s'etablissent dans le monde entier, en particulier dans les pays a faible et moyen revenu, afin de faciliter la collecte, le traitement et la distribution de lait humain provenant de donneuses. Cependant, contrairement a d'autres produits medicaux d'origine humaine, il n'existe aucune norme minimale de qualite, de securite et d'ethique en la matiere, et aucun organe de coordination global n'a ete cree pour guider les politiques nationales. Dans le present document, nous evoquons les principaux obstacles a la progression des banques de lait humain, notamment l'absence de definition claire ou de registre de produits; les problemes relatifs a la reglementation, la qualite et la securite; ainsi que les questions ethiques entourant la commercialisation et l'exploitation potentielle des femmes. Jugeant cette progression limitee par le manque de donnees comparables, nous encourageons a mener d'autres recherches dans ce domaine pour combler les lacunes et fournir des orientations fondees sur des preuves. Nous soulignons egalement la necessite d'offrir un soutien optimal aux meres afin qu'elles puissent produire leur propre lait et allaiter autant que possible immediatement apres la naissance. La Organizacion Mundial de la Salud recomienda la leche humana donada tanto por sus ventajosas propiedades nutricionales y biologicas cuando no se dispone de la propia leche materna como por su reconocido apoyo a la lactancia y al amamantamiento cuando se utiliza de manera adecuada. Cada vez se crean mas bancos de leche humana en todo el mundo, sobre todo en los paises de ingresos bajos y medios, para facilitar la recogida, el procesamiento y la distribucion de leche humana donada. Sin embargo, a diferencia de lo que ocurre con otros productos medicos de origen humano, no existen estandares minimos de calidad, seguridad y etica para la leche humana donada ni un organismo mundial de coordinacion que sirva de base a las politicas nacionales. En este documento se exponen los principales problemas que impiden el progreso de los bancos de leche humana, como la falta de definiciones claras o de registros de productos; los problemas relacionados con la regulacion, la calidad y la seguridad; y las preocupaciones eticas sobre la comercializacion y la posible explotacion de las mujeres. Dado que el progreso de los bancos de leche humana se ve limitado por la falta de evidencias comparables, se recomienda seguir investigando en este campo para compensar los vacios de conocimiento y proporcionar una guia asistencial. Asimismo, se destaca la necesidad de apoyar al maximo a las madres para que se provean de su propia leche materna y establezcan la lactancia materna tan pronto y siempre que sea posible despues del nacimiento.

Human milk provides essential nutrition for infants and holds many health benefits for infants and mothers. When a mother's own milk is not available for her infant, the World Health Organization recommends feeding donor human milk (DHM) from a human milk banking facility. DHM is human milk produced, collected then donated to a human milk bank (HMB). HMBs serve many vital functions, including screening donor mothers, then collecting, processing, storing, and allocating DHM to recipients. The first HMB opened in 1909, and today there are more than 700 HMBs globally. Unfortunately, HMB facilities are not present in all locales, with notable gaps in South Asia and Africa. Additionally, there are no global standards to guide HMB operational procedures. Even though most HMBs attempt to employ quality control systems to provide safe DHM, differences in community needs, resource availability, and a range of methods and policies to execute processes result in significant variations in DHM quality and HMB operations. Robust and collaborative systems that ensure safe and equitable access to DHM are needed. In this paper, we present a global snapshot of current human milk banking practices; review an interdisciplinary framework to guide and support HMB activities as an integrated part of health and newborn care systems; discuss factors that contribute to HMB sustainability; outline barriers to scaling HMBs worldwide; and highlight knowledge, policy, and research gaps. Developing global HMB guidance and rigorous, adaptable standards would strengthen efforts to improve newborn health. Key messages: Safe donor human milk (DHM) from a human milk bank (HMB) is a WHO recommendation when the mother's own milk is not available.Over 700 HMBs exist globally, with varying operational models and a wide range of practices due to lack of global guidelines and the current practice of adaptation to local needs and health systems.Scaling up of HMBs to meet the global demand for DHM would be facilitated by the development of global standards to guide integration with breastfeeding promotion and quality controlled processing to ensure provision of safe DHM.

We assessed the potential effectiveness of human milk banking and lactation support on provision of human milk to neonates admitted in the newborn unit (NBU) at Pumwani Maternity Hospital, Kenya. This pre–post intervention study collected data from mothers/caregivers and their vulnerable neonates or term babies who lacked sufficient mother's milk for several reasons admitted in the NBU. The intervention included establishing a human milk bank and strengthening lactation support. Preintervention data were collected between 5 October 2018 and 11 November 2018, whereas postintervention data were collected between 4 September 2019 and 6 October 2019. Propensity score‐matched analysis was performed to assess the effect of the intervention on exclusive use of human milk, use of human milk as the first feed, feeding intolerance and duration of NBU stay. The surveys included 123 and 116 newborns at preintervention and postintervention, respectively, with 160 newborns (80 in each group) being included in propensity score matched analysis. The proportion of neonates who exclusively used human milk during NBU stay increased from 41.3% preintervention to 63.8% postintervention (adjusted odds ratio [OR]: 2.68; 95% confidence interval [CI]: 1.31, 5.53) and those whose first feed was human milk increased from 55.0% preintervention to 83.3% postintervention (adjusted OR: 5.09; 95% CI: 2.18, 11.88). The mean duration of NBU stay was 27% (95% CI: 5.8%, 44.0%) lower in the postintervention group than in the preintervention group. The intervention did not affect feeding intolerance. Integrating human milk banking and lactation support may improve exclusive use of human milk among vulnerable neonates in a resource limited setting. Key messages: Mother's milk is recommended for feeding preterm and low birthweight neonates.However, when the provision of mother's milk is not feasible, the use of donor human milk—from a human milk bank—is recommended.In this quasi‐experimental study, human milk banking and lactation support intervention increased the exclusive use of human milk during hospital stay and the use of human milk as the first feed among neonates admitted in the newborn unit at Pumwani Maternity Hospital, Kenya.The intervention also reduced the duration of stay in the newborn unit and there was no impact on feeding intolerance.Human milk banking and lactation support may improve the exclusive use of human milk among vulnerable neonates in a resource‐limited setting.

In the context of a prevention of mother to child transmission of HIV program promoting exclusive breast-feeding (EBF) to 6 mo and offering HIV-PCR testing at ~6 mo, we ascertained the feasibility of expressing and heat-treating (EHT) all breast milk fed to HIV-exposed, uninfected infants following 6 mo of EBF. Twenty mother-baby pairs were enrolled from a hospital in rural Zimbabwe. Research nurses provided lactation, EHT, and complementary feeding counseling through 21 home visits conducted over an 8-wk period and collected quantitative and qualitative data on the mothers' EHT experiences, children's diets, and anthropometric measurements. Mothers kept daily logs of EHT volumes and direct breast-feeding episodes. Mothers successfully initiated and sustained EHT for 4.5 mo (range, 1-11 mo), feeding 426 [+ or -] 227 mL/d (mean [+ or -] SD). By wk 2 of follow-up, children were receiving EHT and Nutributter-enriched complementary foods that satisfied 100% of their energy requirements. During the 8-wk follow-up period, no growth faltering was experienced [changes in weight-for-age, weight-for-length, and length-for-age Z scores = +0.03 [+ or -] 0.50; +0.77 [+ or -] 1.59; and +0.02 [+ or -] 0.85 (mean [+ or -] SD), respectively]. Stigma was not a major deterrent, likely due to a social marketing campaign for EBF that promoted EHT as a practice to sustain breast-feeding for all women. This study provides evidence that resource-poor rural women can initiate and sustain EHT given family and health systems support. EHT provides a strategy for improving the diets of HIV-exposed but uninfected children after direct breast-feeding has ceased. doi: 10.3945/jn.110.122457.

A simple method of flash-heat to inactivate HIV in naturally infected breast milk from HIV-positive mothers is investigated. It is indicated that flash-heat is capable of inactivating cell-free HIV-1 in naturally infected breast milk from HIV-positive women.

If maternal milk is unavailable, the World Health Organization recommends that the first alternative should be pasteurised donor human milk (DHM). Human milk banks (HMBs) screen and recruit milk donors, and DHM principally feeds very low birth weight babies, reducing the risk of complications and supporting maternal breastfeeding where used alongside optimal lactation support. The COVID‐19 pandemic has presented a range of challenges to HMBs worldwide. This study aimed to understand the impacts of the pandemic on HMB services and develop initial guidance regarding risk limitation. A Virtual Collaborative Network (VCN) comprising over 80 HMB leaders from 36 countries was formed in March 2020 and included academics and nongovernmental organisations. Individual milk banks, national networks and regional associations submitted data regarding the number of HMBs, volume of DHM produced and number of recipients in each global region. Estimates were calculated in the context of missing or incomplete data. Through open‐ended questioning, the experiences of milk banks from each country in the first 2 months of the pandemic were collected and major themes identified. According to data collected from 446 individual HMBs, more than 800,000 infants receive DHM worldwide each year. Seven pandemic‐related specific vulnerabilities to service provision were identified, including sufficient donors, prescreening disruption, DHM availability, logistics, communication, safe handling and contingency planning, which were highly context‐dependent. The VCN now plans a formal consensus approach to the optimal response of HMBs to new pathogens using crowdsourced data, enabling the benchmarking of future strategies to support DHM access and neonatal health in future emergencies.

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. HMOs were purified from samples and labelled before separation using high-performance liquid chromatography. Concentrations of total HMOs, sialylated and fucosylated HMOs and individual HMOs using the two pasteurisation methods were compared using repeated-measures ANOVA. Results: The study demonstrated no difference in total concentration of HMOs between the two pasteurisation methods and a small but significant increase in the total concentration of HMOs regardless of pasteurisation methods compared with controls (unpasteurised samples) (p<0.0001). Conclusion: The FoneAstra FH pasteurisation system does not negatively affect oligosaccharides in human milk and therefore is a possible alternative for providing safely sterilised human milk for low- and middle-income countries.
