RESUMO

Background and objectives Human milk benefits for both mothers and babies are widely acknowledged. Human milk banks (HMBs) are essential in providing newborns who would not otherwise have access to pasteurized and stored human milk. The objective of this research was to investigate the understanding, opinions, and outlooks of medical and paramedical students regarding breast milk donation and the concept of an HMB. Material and methods A total of 398 professional female students specializing in physiotherapy, nursing, and medicine were given an online self-administered questionnaire as part of a descriptive cross-sectional study. Data on the characteristics, HMB knowledge, awareness levels, and attitudes toward HMB and breast milk donation were to be gathered through the questionnaire. Every student's answer to the survey was kept private and confidential. Result According to the survey, 188 students (47.24%) belong to the medical college, 126 students (31.66%) belong to the physiotherapy college, and the remaining 84 students (21.11%) are from the nursing college. A total of 294 students (74.12%) had heard about human milk banking before and received information from health professionals (195 students, 48.99%), the news (67 students, 16.83%), and family and friends (61 students, 15.33%). However, only 224 students (56.28%) are willing to feed their babies with HMB milk in the future. On the other hand, 216 students (54.27%) are ready to donate breast milk to HMB. The majority of students have a favorable opinion of breast milk donation. A staggering 394 students (98.99%) think that donating human milk can save babies. Furthermore, 379 students (95.23%) think that all the nutrients needed for a baby's healthy development are found in human milk. Merely 350 students (87.93%) think that breastfeeding does not result in malnourishment for either the mother or the baby. When there is an excess of milk, the majority of students (378 or 94.97%) think that there is nothing wrong with donating it. Moreover, 312 (80.41%) students are happy to donate milk in the future. A total of 373 students (93.71%) are overjoyed that a sick baby will survive because of their donated milk. Only 100 students (25.12%) will give milk, though, and only to the infants of their friends and relatives, never to complete strangers. Conclusion A dearth of knowledge pertaining to human milk banking is rampant among medical and paramedical female students, yet the gravity of the circumstances remains concealed. Consequently, it is imperative to extensively educate all Indian communities about the concept of human milk banking to gain widespread acceptance. This research sheds light on the issue and promotes scientific knowledge of HMB, as many students are unaware of it.

RESUMO

Breastfeeding is a crucial public health approach that reduces infant morbidity and mortality by providing essential nutrients and antibodies, and breast milk is easily digested. Breastfeeding and donated milk serve as a preventative measure against necrotising enterocolitis. Additionally, they protect against viruses and nosocomial sepsis. When a birthing parent's own milk is unavailable, alternative enteral nutrition for preterm or low-birth-weight infants is either donor human milk (DHM) or artificial formula. This study aimed to understand mothers' acceptance of the donor human milk bank (DHMB) and DHM. A qualitative phenomenological study was conducted in Limpopo Province, South Africa. The study used purposive sampling to select 23 mothers in postnatal and neonatal wards. Data collection was via in-depth interviews using a semistructured interview guide. Manual data analysis using an interpretative phenomenological analysis (IPA) framework was used to coding. Concepts were grouped to generate themes. Three themes and nine subthemes were generated: (1) DHMBs (2) cultural perspective of DHMB, and (3) health considerations of DHM. Participants were unaware of the DHMB. Hesitancy in accepting DHM due to fear of contracting HIV was observed. Cultural beliefs are an influencing factor for use, while donation was driven by altruistic reasons, preventing waste, helping others and having previously benefited from DHM. The study found that mothers are willing to donate human milk. Willingness to donate can be increased by raising awareness about DHMB and addressing culture and safety concerns at antenatal clinics.

RESUMO

Where a mother's own milk is not available or is insufficient, donor human milk (DHM) processed by a human milk bank (HMB) is the recommended next best alternative. HMBs exist in over 65 countries. However, most countries have yet to establish national policies or programmes that support the provision of DHM. In July 2019, a group of international experts in fields relevant to human milk banking gathered at a meeting organised by the Institute of Biomedical Ethics, University of Zurich, and co-sponsored by the World Health Organisation. Prompted by the growing interest globally in creating and sustaining HMBs and addressing current safety and ethical concerns and standards, the aims of the meeting were to define knowledge gaps, determine the need for and scope of global guidelines and provide recommendations on steps that need to be taken at the international level. Following wide-ranging discussions that included the integration of milk banks into health care systems, strategy and policy, quality and safety, the use of DHM and associated ethical considerations, the overall conclusion of the meeting was that in the absence of global recommendations on the implementation, operation and regulation of HMBs, evidence-based guidance is urgently needed.

RESUMO

Introduction: Human breast milk (HBM) contains a complex and dynamically changing variety of factors that contribute to the infant's developing immune system's ability to fight upper respiratory tract infections, including otitis media (OM). We sought to summarize the current evidence on the protective characteristics of HBM, through direct or donated feeding, toward early childhood OM. Methods: For this narrative review, we performed a literature search on OM in the context of HBM feeding in the PubMed, Embase, and Google Scholar databases, between January 1, 2008, and July 1, 2023. Results: Immunoglobulin A (IgA) provides a short-term immunity of 2-3 days against otopathogens causing OM. IgA-mediated immunity is effective against OM up to 7 months of age if breastfeeding continues. The role of transferred IgM and IgG in HBM is unclear. Although there is a potential protective value of microRNA, hormones, oligosaccharides, stem cells, and interleukins present in HBM, their role is unclear. Any duration of breastfeeding is superior to no breastfeeding in OM risk reduction, with a big variability among studies (odds ratio 0.23-0.81, depending on the duration). Duration of breastfeeding ≥6 months was found to be the most effective in OM risk reduction, but there was no evidence of continued benefits after 2 years of age. Expressed breastfeeding was not shown to be more beneficial. The protective values of donor HBM against OM are still undetermined. Conclusion: HBM has numerous components that contribute to protection against early childhood OM.

RESUMO

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.

RESUMO

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.

RESUMO

Background: Human milk banking has become an important aspect of Nutritional medicine. It is not just about the provision of mother's own milk (MOM) or donor human milk (DHM) in the hospital, but also a strategy to encourage breastfeeding in the clinical setting and beyond. Objective: To describe the feeding patterns of hospitalised infants including human milk dispensed by the Leipzig Donor Human Milk Bank (LMB). Design: A descriptive analysis of daily data on milk feeds dispensed by LMB for hospitalised infants distinguishing between MOM or DHM, either fresh or frozen, and raw/pasteurised milk from 2012-2019. Results: We included 2,562 infants with median hospitalisation of 23 days, for whom human milk was dispensed on median 76% of those days and other nutrition on the remaining days. Raw MOM and raw DHM comprised 52% and 8% of the dispensed milk, respectively. Dispensing exclusive DHM instead of MOM for at least one full day was required for 55% of the infants, mostly at the beginning but also later during hospitalisation. Exclusive raw DHM was dispensed on at least 1 day for 37% of the infants, in different birthweight strata <1,000 g: 10%, 1,000-1500 g: 11%, 1,500-2500 g: 13% and > 2,500 g: 3%. At discharge, MOM was dispensed for more than 60% of the infants. Conclusion: During an infant's hospital stay, LMB dispenses various human milk feeds with interspersed DHM resulting in complex intra-individual and time-variant feeding patterns. LMB dispenses raw MOM and especially raw DHM with the intention to retain the properties of human milk unlike a diet containing pasteurised DHM and/or formula. Although raw DHM comprises a small percentage of all dispensed milk, raw DHM is dispensed for a substantial portion of infants. Our results document that dispensing raw DHM, is possible in routine settings.

RESUMO

Introduction: The gastrointestinal and immune systems of premature infants are not fully developed, rendering them more vulnerable to severe complications like necrotizing enterocolitis. Human milk offers a rich array of bioactive factors that collectively contribute to reducing the incidence of gut infections and inflammatory conditions. When a mother's milk is unavailable, preterm infants are often provided with donor human milk processed in Human Milk Banks. However, it remains uncertain whether pasteurized milk confers the same level of risk reduction as unprocessed milk. This uncertainty may stem from the well-documented adverse effects of heat treatment on milk composition. Yet, our understanding of the comprehensive impact on protective mechanisms is limited. Methods: In this study, we conducted a comparative analysis of the effects of raw versus pasteurized milk and colostrum versus mature milk on cellular functions associated with the gut epithelial barrier and responses to inflammatory stimuli. We utilized THP-1 and HT-29 cell lines, representing monocyte/macrophages and gut epithelial cells, respectively. Results: Our observations revealed that all milk types stimulated epithelial cell proliferation. However, only raw colostrum increased cell migration and interfered with the interaction between E. coli and epithelial cells. Furthermore, the response of epithelial and macrophage cells to lipopolysaccharide (LPS) was enhanced solely by raw colostrum, with a milder effect observed with mature milk. In contrast, both raw and pasteurized milk diminished the LPS induced response in monocytes. Lastly, we examined how milk affected the differentiation of monocytes into macrophages, finding that milk reduced the subsequent inflammatory response of macrophages to LPS. Discussion: Our study sheds light on the impact of human milk on certain mechanisms that potentially account for its protective effects against necrotizing enterocolitis, highlighting the detrimental influence of pasteurization on some of these mechanisms. Our findings emphasize the urgency of developing alternative pasteurization methods to better preserve milk properties. Moreover, identifying the key components critically affected by these protective mechanisms could enable their inclusion in donor milk or formula, thereby enhancing immunological benefits for vulnerable newborns.

RESUMO

Objectives: This study aimed to investigate the matching degree between the donated supply and demand, clinical characteristics of both donors and recipients, along with the operation cost. Methods: From January 1, 2018 to December 31, 2021, the data on human milk donation and usage, the clinical characteristics of donors and recipients, and the cost of each operating center were collected from the Manual Donation Registration Form and Information Management System of the selected human milk bank. Results: During the four years that the human milk bank was in operation, the volume of donated milk was slightly greater than the volume of consumed milk. A total of 1364 donors donated 2434.63 liters of qualified human milk, for RMB 1,791,000 (USD 257, 202), ie, RMB 385.3 (USD 55.3)/L; 97.8% of the donors were preterm puerperae, and 59% of the donors donated between 1 week and 1 month after delivery. All recipients were preterm infants and received donated human milk for a duration of 9.4 days on average. During the four years of operation, the proportion of donors who had previously received donated milk among all donors showed an overall increasing trend, while the incidence of NEC in preterm infants gradually decreased. Conclusions: The increasingly optimized structure of donors, the more economical operation, and the fact that the use of donated milk may not affect breastfeeding of the recipients have made it a human milk bank operation mode worthy of promotion.

RESUMO

Background/Objective: As human milk banking services expand, information about lifestyle characteristics and infant feeding experiences of milk bank donors is relatively limited. Our goal was to describe and compare milk bank donors' demographic, clinical, and lifestyle characteristics, and breastfeeding experiences in a variety of geographic settings. Methods: A cross-sectional online survey was conducted from August 2022 to December 2022 with approved donors from three milk banks in the United States (n = 369), and one milk bank in United Kingdom (n = 187). Results: Donors in all settings were predominantly in their early 30s, White, married, educated, and identified as female. U.K. donors reported more frequently being on maternity leave (33% versus 5%, p < 0.001), predominantly feeding directly at the breast in the first 3 months postpartum (51% versus 28%, p < 0.001), and breastfeeding a single child longer (21.2 versus 13.3 months, p < 0.001) than U.S. donors. Significantly more U.S. donors reported pumping due to work (34% versus 11%, p < 0.001) and pumping multiple times per day (57% versus 36%, p < 0.001). Most donors reported receiving information about breastfeeding from a health care provider (94% United States and 88% United Kingdom, p = 0.022), while the internet was the most popular source of information about pumping (65% United States and 64% United Kingdom, p = 0.751). Conclusion: Factors not directly related to milk banking (e.g., maternity leave, sources of breastfeeding/pumping assistance) may have an impact on how donors feed their children and ultimately on their milk donation pattern. The impact of donor characteristics and feeding practices on donation patterns warrants further investigation.

RESUMO

Background: Donor human milk (DHM) is essential to the operation of human milk banks (HMB). This study examined characteristics and factors associated with higher volumes of DHM donation at the first HMB in Vietnam. Method: Data from an online HMB monitoring system collected between February 2017 and July 2022 included demographic characteristics, child information, the timing of donation, and the volume of DHM. Higher volume is defined as equal to or greater than the median DHM volume per donor of 14.4 liters (L). Potential contributors to higher DHM volume were examined using the chi-square test in univariate and multivariable logistic regression analysis. Results: During the 5.5-year operation, this HMB recruited 517 donors with an average age of 28.6 years. Approximately 60.9% of donors had a college or higher degree and 97.3% gave birth in Da Nang city. Of these donors, the prevalence of cesarean birth was 48.2%, preterm births was 40.2%, and 27.9% had babies with a birth weight of less than 1,500 g. There was a similar proportion of donors between the hospital (48.2%) and community (51.8%). On average, hospital donors started their donations 15 days after birth when their newborns were 33.9 weeks corrected age compared to 63 days and 47.7 weeks among community-based donors. The overall median volume of DHM per donor was 14.4 L over a period of 46 days. The amount and duration were higher in community-based donors (17.5 L in 72 days, 300 ml/day) than those in the hospital (8.4 L in 30 days, 258 ml/day). More than 37% of donors contacted the HMB themselves; the remainder were introduced by health professionals. Factors associated with higher volumes of DHM included higher education (OR: 1.77; 95% CI: 1.09, 2.87), having a full-term newborn (OR: 2.46; 95% CI: 1.46, 4.13), and community-based donors (OR: 2.15; 95% CI: 1.22, 3.78). Conclusions: Mothers with higher education and from the community donate more breastmilk over a longer duration than those with lower education and from the hospital. Breastfeeding protection, promotion, and support should be offered to all mothers with specialized breastfeeding support for mothers of preterm and sick infants. This will ensure mothers have sufficient breastmilk for their newborns and potentially surplus breastmilk for donation.

RESUMO

Background: Mother's milk is the ideal food for a neonate. When mother's milk is unavailable for any reason, pasteurised donor human milk (PDHM) is the next best option. This quality improvement (QI) project aimed at improving voluntary donation in a public human milk bank (HMB) in South India. Methods: Between January 2018 and June 2019, the HMB received an average of 15 L of donor milk per month (0.5 L/day). Our aim was to increase voluntary donation by 50% from the baseline over a period of 8 months from July 2019 to March 2020 using QI methods. Two plan-do-study-act (PDSA) cycles were done during the intervention period (4 months). Interventions included the formation of micro teams in postnatal wards to promote exclusive breastfeeding and to liaison with the core QI team. We created a milk expression area in the postnatal ward, counseled postnatal mothers, and addressed supply chain issues like sterile pumping accessories. Results: The average daily voluntary milk donation to HMB increased from 0.83 L/day in the baseline phase to 1.16 and 1.14 L per day in the intervention and postintervention phases, respectively. The mean (SD) monthly donated volumes increased from 28.2 (6.1) L to 34.1 (3.7) L; mean difference (95% CI) 5.9 (0.33-11.4); P = 0.03. The volume of PDHM disbursed from HMB increased from 26.6 (3.2) L/month to 32.2 (9.2) L/month, although not statistically significant (p = 0.15). The number of mothers donating milk did not increase during the study period. Conclusions: A multipronged QI intervention effort focusing on exclusive breastfeeding improved voluntary milk donation in HMB bank. Multiple micro-teams and local networking facilitated the QI initiative.

RESUMO

Background and Objective: Donor human milk (DHM) from the human milk bank (HMB) is the next best alterative in circumstances when mother's own milk is not available. There was a steep decline in the volume of DHM collected during the coronavirus disease-19 (COVID-19) pandemic due to various factors, while DHM demand increased. Hence, a quality improvement (QI) study was conducted to increase the volume of milk donation to HMB from postpandemic baseline of 300-400 to 1,000 mL/day over 8 weeks. Materials and Methods: Fish bone analysis was used to identify the potential barriers, and four Plan-Do-Study-Act (PDSA) cycles were conducted from January 2021 to March 2021 to address the key barriers. In the first PDSA cycle, training of health care providers was done. Sessions for educating mothers in the second PDSA cycle and individualized one-to-one counseling of mothers by a mother support group were done in the third PDSA cycle. The availability of breast pump was increased in the fourth PDSA cycle. Sustainability of the interventions was studied for 6 months and data were analyzed. Results: The average DHM collected per day at the end of each PDSA cycle was 900, 1,500, 1,000, and 1,100 mL. Although the sustenance phase was affected by the second COVID-19 wave, prompt identification of the issues and timely interventions prevented the donated volume from dropping to preintervention levels. Conclusion: QI initiatives customized for local settings can result in significant improvement in voluntary milk donation in HMB, which can result in more availability of DHM to premature babies.

RESUMO

Bacillus cereus is reported as a common cause of toxin-induced food poisoning and of contamination in pasteurized human milk donations. As various toxins can be produced by B. cereus, the aim of this work was first to investigate the toxigenic potential and profiles of 63 B. cereus isolates from Amiens Picardie human milk bank. A comparison to the toxigenic profiles of 27 environmental B. cereus isolates harvested in the hospital in which this human milk bank is situated was performed. Toxin gene prevalences were the highest for nhe (ABC) and entFM followed by cytK and hbl(ACD). A 27% prevalence was found for ces human milk isolates, which is higher than previous works reporting on pasteurized milk and dairy products. No significant differences could be found between human milk and environmental isolates regarding toxin gene prevalences and/or toxin gene profiles. The second aim was to establish whether a B. cereus cross-contamination between human milk and the environment could occur. This was achieved with the help of Fourrier-transform infra-red spectroscopy which enabled the discrimination of 2 main clusters of 11 and 8 isolates, each containing human milk and Amiens Picardie human milk bank environmental isolates. For these two clusters, the time sequence showed that human milk isolates were the first to occur and might have contaminated the milk bank environment as well as other human milk donations. Routinely used on B. cereus isolates, Fourrier-transform infra-red spectroscopy could help in rapidly detecting such clusters and in limiting the spread of a B. cereus strain that might generate rejection of pasteurized donation by the human milk bank.

RESUMO

The influence of the diet and nutritional status of milk donors on the nutritional composition of donor human milk (DHM) is unknown. The present study aimed to determine the nutritional profile of DHM and the associations between donors' dietary intake and nutritional status and the micronutrient and lipid composition in DHM. For this purpose, 113 donors completed a food frequency questionnaire, provided a five-day weighed dietary record, and collected milk for five consecutive days. Nutrient determinations in donors' erythrocytes, plasma, urine, and milk were performed. Multiple linear regressions were conducted for the evaluation of the associations. We highlight the following results: DHM docosahexaenoic acid (DHA) was positively associated with donors' plasma DHA content and donors' DHA intake (R2 0.45, p < 0.001). For every 1 g/day DHA intake, an increase of 0.38% in DHA content and 0.78% in total omega-3 content was observed in DHM (R2 0.29, p < 0.001). DHM saturated fatty acids were positively associated with erythrocyte dimethyl acetals, plasma stearic acid, trans fatty acids intake, and breastfeeding duration and negatively associated with erythrocyte margaroleic acid (R2 0.34, p < 0.01). DHM cholecalciferol was associated with plasma cholecalciferol levels and dairy intake (R2 0.57, p < 0.01). Other weaker associations were found for free thiamin, free riboflavin, pyridoxal, dehydroascorbic acid, and the lipid profile in DHM. In conclusion, the diet and nutritional status of donors influence the fatty acid profile and micronutrient content of DHM.

RESUMO

Donor human milk (DHM) is the second-best nutrition for preterm infants when their own mother's milk is unavailable. The nutrient content of human milk is influenced by various factors, including gestational and postpartum age, but there are no data regarding DHM composition in Japan. The aim of this study was to determine the protein and immune component content of DHM in Japan and to elucidate the effects of gestational and postpartum age on nutrient composition. From September 2021 to May 2022, 134 DHM samples were collected from 92 mothers of preterm and term infants. Protein concentrations in preterm DHM (n = 41) and term DHM (n = 93) were analyzed using a Miris Human Milk Analyzer. The concentrations of secretory immunoglobulin A (sIgA) and lactoferrin, major immune components, were measured using enzyme-linked immunosorbent assays. Preterm DHM exhibited higher protein content than term DHM (1.2 g/dL and 1.0 g/dL, respectively, p < 0.001), whereas sIgA content was higher in term DHM than in preterm DHM (110 µg/mL and 68.4 µg/mL, respectively, p < 0.001). Gestational age was negatively correlated with protein levels and positively correlated with sIgA and lactoferrin levels. Furthermore, a negative correlation was found between postpartum week and protein, sIgA, and lactoferrin concentrations. Our data suggest that gestational and postpartum age affects protein, sIgA, and lactoferrin concentrations in DHM. These results indicate the importance of nutritional analysis for the appropriate use of DHM in preterm infants.

Women of childbearing age in Western societies are increasingly adopting vegetarian diets. These women are sometimes rejected as milk donors, but little about the composition of their milk is known. The present study aimed to compare the intake, nutritional status, and nutritional composition of human milk from omnivore human milk donors (Donors) and vegetarian/vegan lactating mothers (Veg). Milk, blood, and urine samples from 92 Donors and 20 Veg were used to determine their fatty acid profiles, as well as vitamins and minerals. In a representative sample of both groups, we also determined the lipid class profile as a distribution of neutral and polar lipids, the molecular species of triacylglycerols, and the relative composition of phospholipids in their milk. A dietary assessment was conducted with a five-day dietary record (while considering the intake of supplements). We highlight the following results, expressed as the mean (SE), for the Veg vs. Donors: (1) Their docosahexaenoic acid (DHA) intake was 0.11 (0.03) vs. 0.38 (0.03) g/day; the plasma DHA was 0.37 (0.07) vs. 0.83 (0.06)%; and the milk DHA was 0.15 (0.04) vs. 0.33 (0.02)%. (2) Their milk B12 levels were 545.69 (20.49) vs. 482.89 (4.11) pM; 85% of the Veg reported taking B12 supplements (mean dose: 312.1 mcg/day); and the Veg group showed no differences with Donors in terms of total daily intake or plasma B12. (3) Their milk phosphatidylcholine levels were 26.88 (0.67) vs. 30.55 (1.10)%. (4) Their milk iodine levels were 126.42 (13.37) vs. 159.22 (5.13) mcg/L. In conclusion, the Vegs' milk was shown to be different from the Donors' milk, mainly due to its low DHA content, which is concerning. However, raising awareness and ensuring proper supplementation could bridge this gap, as has already been achieved for cobalamin.

RESUMO

BACKGROUND: In Japan, the first human milk bank (HMB) was established in 2017, which changed the practice of enteral feeding in neonatal care. This study investigated the practice of enteral feeding of preterm infants after the establishment of the HMB in Japan and examined related future issues. METHODS: A survey on enteral feeding and the use of the HMB was conducted in 251 neonatal intensive care units (NICUs) from December 2020 to February 2021. RESULTS: The response rate was 61%. The ideal times to start enteral feeding for extremely-low-birthweight infants (ELBWI) and very-low-birthweight infants (VLBWI) were within 24 h after birth in approximately 59% and 62% of NICUs, however, only 30% and 46% could do so, respectively. Artificial nutrition was used to initiate enteral feeding for ELBWIs and VLBWIs in in 24% and 56% of NICUs, respectively. Of the NICUs, 92% considered the HMB "necessary" or "rather necessary". Fifty-five percent wanted to use the HMB but could not. The major reasons for this were (1) difficulty in paying the annual membership fee, (2) difficulty obtaining approval from the NICU, and (3) complexity in using the facility. The indications for using and discontinuation of use of donor milk varied among the NICUs. Only in 17%, milk expression was within 1h after delivery. CONCLUSIONS: Compared with before the establishment of the HMB, NICUs are currently more willing to start enteral feeding for preterm infants earlier. However, the implementation of enteral feeding appears to be challenging. Issues related to the HMB highlighted by the responses need to be addressed. Additionally, guidelines for using donor milk should be established.

RESUMO

In Europe, an increasing number of human milk banks (HMBs) collect donor human milk to feed preterm infants when their mother's milk is not available or not enough. Moreover, donor milk is a bridge to breastfeeding, with positive clinical and psychological advantages for both mother and infant. Italy, with 41 HMBs actively operating in 2022, has the highest number of HMBs in Europe. The process of human milk donation is complex, so activity of HMBs must be regulated according to well-established rules. The present recommendations have been prepared as a tool to standardize the organization, management, and procedures of HMBs operating in Italy and to determine the minimal essential requirements to establish new HMBs. This article covers all the aspects of human milk donation and human milk banking, including general recommendations, donor recruitment and screening, expression, handling and storage of donor human milk, milk screening, and milk treatment (pasteurization). A pragmatic approach was taken to drafting the recommendations. Items for which there was consensus or robust published evidence on which to base recommendations were included. When there were differences that could not be resolved by reference to published research, a statement of explanation based on the expert opinion of the authors (all members of the Italian Association of Human Milk Banks) was included. Implementation of these recommendations can contribute to promotion of breastfeeding.

RESUMO

Background: Microbiological quality is one of the key safety standards in human milk bank (HMB) operations. We describe the profiles of bacteria in donor human milk (DHM) before and after the pasteurization of samples collected from breastfeeding women in the hospital and from the community in the first HMB in Vietnam. Methods: Data were collected between February 2017 and January 2022 from an online HMB monitoring system. First, DHM samples were cultured, and the number of colony-forming units (CFU) were counted before (n = 708) and after pasteurization (n = 1146). The gram-staining method combined with the Vitek 2 Compact system were used to identify types of organisms at the Da Nang Hospital for Women and Children's Laboratory. Passing criteria for DHM included pre-pasteurization samples had a total colony count <105 CFU/mL and post-pasteurization was <10 CFU/mL. Results: During five years of operation, Da Nang HMB had 491 donors (48.7% were hospital and the rest community donors) who donated an average amount of 14.2 L over 45 days. Of this DHM volume, 84.9% of donor samples passed the pre- and post-pasteurization microbiological tests. DHM from community donors had a higher pass rate (87.8%) compared to that from hospital donors (79.5%). Before pasteurization, 15.4% of DHM samples had a bacteria count <103 CFU/mL, 63.0% had 103-<105 CFU/mL, and 21.6% had ≥105 CFU/mL. Most of the unpasteurized DHM samples (93.0%) had microorganism growth: with one organism (16.4%), two (33.9%), three or more (43.6%). After pasteurization, 17.9% samples had a bacteria count of 1−9 CFU/mL and 7.2% had ≥10 CFU/mL. DHM samples from community donors had a lower bacterial count and number of organisms than those from hospital donors both before and after pasteurization. The highest microorganisms from unpasteurized DHM samples were Staphylococcus epidermidis (74.2%), Acinetobacter sp. (52.1%), gram-positive bacillus (51.7%), Staphylococcus coagulase-negative (15.8%), and Staphylococcus aureus (10.5%). Common microorganisms from pasteurized DHM were gram-positive bacillus (21.0%), Staphylococcus epidermidis (3.9%), and Acinetobacter sp. (0.9%). Samples from the hospital tended to have a higher contamination with those microorganisms than those from community donors. Conclusions: The majority of DHM samples in Da Nang passed microbiological testing criteria. DHM from community donors had higher pass rates than hospital donors. Corrective actions are needed to improve HMB operations and hospital microbiological quality standards, as well as general improvements in water and sanitation.
