Psychological factors and barriers to donating and receiving milk from human milk banks: A review.

Human milk banks (HMBs), established in the early 20th century, aimed to provide safe breast milk for infants with challenges obtaining it. The spread of infections since the 1980s resulted in strict regulations and screening in HMBs, to ensure the safety of donated milk. Several social and personal factors discourage mothers from practicing breastfeeding, making donated milk a viable alternative because of its protective and immunity-enhancing properties. However, psychological barriers can affect the decision to donate or receive donated milk. To identify psychological factors related to donating and receiving human milk from HMBs, we searched PubMed to identify studies reporting psychological factors in donating and receiving milk and excluding studies not reporting psychological factors. The search identified 28 articles meeting the inclusion criteria. Eligible studies from various countries spanned from 1995 to 2023 and focused on psychological factors influencing milk donation and receiving. Most studies were descriptive-qualitative. Factors facilitating or hindering milk donation and reception included perceptions, psychological aspects, and previous experiences. Positive factors for donors included the desire to help other mothers, support from health care professionals, and personal well-being. Negative factors included breast milk exclusivity and discomfort caused by health checks. For recipients, awareness of donated milk benefits was a positive factor, whereas fear regarding safety was negative. The altruistic motivation to help other mothers drove many women to donate. Proper awareness and support from health care professionals and families can help women understand the value of milk donation and support their personal and identity reintegration, especially in cases of the loss of a child.

Determining Knowledge and Opinions of Neonatal Intensive Care Unit Nurses on Wet-Nursing and Human Milk Banks: A Cross-Sectional Study in Türkiye.

BACKGROUND: Wet nursing and human milk banks are vital sources of human milk for infants unable to breastfeed. RESEARCH AIM: This study aims to determine the knowledge and opinions of neonatal intensive care unit nurses regarding wet-nursing and human milk banks in Türkiye. METHODS: This descriptive cross-sectional study was conducted with 219 neonatal intensive care unit nurses using an online survey comprising 20 questions. The data were collected between August and September 2021. RESULTS: Among the participants, 64.4% (n = 141) expressed that they would be a wet-nurse and 59.8% (n = 131) would search for a wet-nurse if necessary. Some, 47.0% (n = 103) of participants did not know if there were any human milk banks in Türkiye, 53.9% (n = 118) would like to be a donor if human milk banks were established, and 71.7% (n = 157) stated that the establishment of human milk banks should be supported. Religious concerns were the basis for reluctance to donate milk to human milk banks for 60% (n = 51) of the participants. Knowledge was greater and opinions about wet-nursing and human milk banks were more positive for participants with higher education, more time in the neonatal intensive care unit, or work at a tertiary care center. CONCLUSION: The approaches of neonatal intensive care unit nurses towards personally being wet-nurses and milk sharing were generally positive, although more information about human milk banks is needed. Religious beliefs are an important consideration when providing information about milk sharing.

Comparative analyses of holder pasteurization vs. HTST pasteurization for donor milk: a cost-minimization study applicable to human milk banks.

BACKGROUND: High-temperature short-time (HTST) pasteurization (72-75 °C, 15 s) is an alternative treatment to traditional Holder pasteurization (HoP) (62ºC, 30 min) for donor milk. HTST pasteurization guarantees the milk's microbiological safety and retains more of its biologically and nutritionally active compounds, but the cost of implementing this technology for a human milk bank is unknown. METHODS: A cost-minimization study was carried out on the facilities of a regional human milk bank in a public hospital. Total production costs (fixed plus variables) were quantified using HTST pasteurization and HoP in three hypothetical scenarios: (1) costs of the first 10 L of pasteurized milk in a newly opened milk bank; (2) costs of the first 10 L of pasteurized milk in an active milk bank; and (3) costs using the maximum production capacity of both technologies in the first two years of operation. The following costs were analyzed: health care professionals, equipment and software, external services, and consumables. RESULTS: In scenario 1, the total production costs were € 228,097.00 for the HTST method versus € 154,064.00 for the HoP method. In scenario 2, these costs were similar (€ 6,594.00 for HTST pasteurization versus € 5,912.00 for HoP). The cost of healthcare professionals was reduced by more than half when pasteurization was carried out by the HTST method versus the Holder method (€ 84.00 and € 191.00, respectively). In scenario 3, the unit cost of milk pasteurized by the HTST method decreased from the first to the second year by 43.5%, while for the HoP method, it decreased by 30%. CONCLUSIONS: HTST pasteurization requires a high initial investment in equipment; however, it provides a significant minimization of production costs in the long term, pasteurizes large quantities of donor milk per working day and achieves a more efficient management of the time of the health care professionals in charge of the bank's operation compared to HoP.

Postpasteurization Testing of Human Milk Sterility at Human Milk Banks in Resource-Limited Settings: An Alternative to Standard Microbiological Quality Testing.

Introduction: Pasteurized donor human milk provides nutrition and bioactive factors for infant growth and health when a mother's own milk is not available. Bacteriological testing is recommended for each pasteurized batch of donor milk before distribution to ensure that the milk is safe for use. Charm Peel Plates (CPPs) are a simplified, easy-to-use culture method for detecting microorganisms in milk and milk products. This study investigates the feasibility of using CPPs as an alternative test for current standard postpasteurization screening by human milk banks (HMBs), particularly those in resource-limited settings. Aim: The aim of this study was to evaluate the feasibility of using the CPP versus the 5% horse blood agar (HBA) plate (standard South African National Health Laboratory Service method) for detecting bacterial growth in pasteurized human milk samples. Methods: For each of the 50 pasteurized donor milk samples, 100-µL aliquots were cultured on routine HBA and 1 mL on CPPs for the total bacterial colony count. Any positive growth was identified using VITEK® 2 (bioMérieux). To demonstrate the ability of CPPs to support bacterial growth, four spiked samples were tested. Results: Concurrent negative test results were reported for 49/50 (98%) samples with only one positive test with HBA. Conclusions and Recommendations: The CPP is equivalent to HBA for detection of bacterial growth. Additional advantages of CPPs are ease of use and cost-effectiveness. The CPP is therefore recommended as a point-of-care, bacteriological screening method for donor human milk by HMBs, particularly those in resource-limited settings.

Temperature curve of raw human milk heated by different methods: experimental study / Curva de temperatura de la leche humana cruda sometida a calentamiento por diferentes métodos: estudio experimental / Curva de temperatura do leite humano cru submetido à aquecimento por diferentes métodos: estudo experimental

ABSTRACT Objective: To analyze the temperature curve of raw or pasteurized human milk exposed to different heating methods. Method: Experiments with volumes of 5 ml to 100 ml of human milk were carried out between 2016 and 2021 and analyzed according to the exposure time by different heating methods. Descriptive statistics included the calculation of means, medians, minimum and maximum values, measures of dispersion and standard deviation. Results: The thermal curve made it possible to identify the heating of human milk close to body temperature when subjected to a water bath and microwaves. Milk exposed to room temperature (21°C) was unable to reach this temperature. When heated in a water bath at 40°C, smaller volumes reached body temperature between 3 and 5 minutes, while in a microwave at 50% power, practically all volumes reached temperature. Conclusion: The temperature curves of raw or pasteurized human milk were constructed, and it was possible to verify its behavior using different heating methods for administering the food in a neonatal intensive care unit, considering the volume, type and time of heating and temperature.

Abstract Objectives: to analyze the donation of human milk at the Banco de Incentivo e Apoio a Amamentação (BIAMA) (Breastfeeding Incentive and Support Bank) from 2018 to 2020. Methods: normative assessment, descriptive and exploratory character, with a quantitative approach and focus on the Donabedian Model. Study with a locus at BIAMA at Dom Malan Hospital, in the city of Petrolina-PE, based on registrations from the online platform of the Rede Brasileira de Bancos de Leite Humano (Brazilian Network of Human Milk Banks), with data from BIAMA from 2018 to 2020 and field activities. Results: in 2020, there was a decrease in the number of group assistance and medical consultations, in contrast to the increase in nursing consultations. Most of the milk supply comes from the external public, and in 2020 there was a reduction number of donors and in the volume of human milk collected. Conclusions: COVID-19 pandemic had a negative impact on BIAMA activities and on milk donation, however, the use of new means of communication for patient care was observed. Even so, new donor recruitment strategies must be implemented. Regarding the main norms that regulate the operation of Human Milk Banks, most of the items listed are obeyed by BIAMA.

Human Milk for Vulnerable Infants: Breastfeeding and Milk Sharing Practice among Ghanaian Women.

Human milk has the best impact on childhood survival. In Ghana, it is estimated that 43% of women exclusively breastfeed for 0-5 months and only 42% of breastfeeding mothers continue through 20-23 months. Although the Ghanaian government has implemented policies to facilitate exclusive breastfeeding, substantial gaps to achieve optimal newborn health and wellbeing remain. The purpose of this study was to evaluate breastfeeding prevalence and human milk sharing practices among Ghanaian women. Qualitative responses were received from Ghanaian females (n = 1050). In our sample, 81% indicated they breastfed their children and 8% reported ever sharing breastmilk with another mother. Reasons for sharing milk included (i) insufficient breastmilk production of the recipient mother, and (ii) mother's unavailability prompting women to offer their milk to a crying baby. About 60% of our sample reported that they were not concerned about sharing their milk. Findings present a strong indicator for milk donation towards the establishment of a human milk bank in Ghana. Health promotion efforts should aim at increasing education about the risks involved in milk sharing as well as the benefits of human milk donation through formal and safer channels such as a Human Milk Bank.

Factors That Influence the Sustainability of Human Milk Donation to Milk Banks: A Systematic Review.

Donor human milk is the recommended alternative for feeding preterm or low birth weight infants when the mother's own milk is unavailable or not in sufficient quantity. Globally, the needs of vulnerable infants for donor human milk exceed the supply. This review aimed to identify the factors impacting the sustainability of human milk donation to milk banks. A systematic review of the literature was performed on eight databases to retrieve articles published until December 2021. The study protocol is available in PROSPERO (#CRD42021287087). Among the 6722 references identified, 10 studies (eight quantitative observational and two qualitative) met the eligibility criteria for a total of 7053 participants. Thirty factors influencing the sustainability of the donations to milk banks were identified and categorized as follows: (1) donation duration, (2) donors' infant features (e.g., gestational age, birth weight), (3) donors' features (e.g., socio-demographic characteristics, milk donation history), and (4) factors related to the milk bank and health care systems (awareness and support). The available evidence suggests that larger volumes of donated milk are associated with a longer duration of donation, as are early donation, previous milk donation, and donors with an infant of smaller weight and gestational age. Supporting and encouraging early donation and recruiting donors with infants of low birth weight and low gestational age could support longer donation times and greater volumes of milk donated. To identify efficient strategies and to draw appropriate recommendations to improve donor milk access, future studies should further explore the issues of the sustainability of human milk donation to milk banks.

Relationship Between Maternal COVID-19 Infection and In-Hospital Exclusive Breastfeeding for Term Newborns.

OBJECTIVE: To evaluate the relationship between maternal COVID-19 infection and the odds of in-hospital exclusive breastfeeding for term newborns. DESIGN: Retrospective descriptive quantitative. SETTING: A large, urban hospital with more than 6,000 births annually. SAMPLE: Term newborns born between March 1, 2020, and March 31, 2021 (N = 6,151). METHODS: We retrospectively extracted data from electronic health records to evaluate the relationship of maternal COVID-19 infection with the odds of in-hospital exclusive breastfeeding using univariate analysis and logistic regression models. The covariates included insurance type, race/ethnicity, glucose gel administration, length of stay, newborn gestational age, newborn birth weight, and maternal COVID-19 infection. RESULTS: Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding (p = .138) after adjustment for covariates in the logistic regression model. However, when newborns who received pasteurized donor human milk supplementation were excluded from the logistic regression model, maternal COVID-19 infection significantly decreased the odds of in-hospital exclusive breastfeeding (p = .043). CONCLUSION: Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding when newborns received donor human milk supplementation. Access to donor human milk for supplementation for term newborns may protect the odds of in-hospital exclusive breastfeeding.

Microbiological Quality of Milk Donated to the Regional Human Milk Bank in Warsaw in the First Four Years of Activity.

As the survival rate for preterm infants increases, more emphasis is placed on improving health-related quality of life through optimal nutritional management. Human Milk Banks (HMBs) provide bioactive nutrients and probiotic microorganisms to premature newborns, especially in the first year of life. Donated milk screening and selection of potential donors ensures the quality and microbiological safety of the donated milk. Therefore we reviewed the basic characteristics of donors and the amounts and contamination of breast milk donated to the Regional Human Milk Bank (RHMB) in Warsaw. In four years, the RHMB collected 1445.59 L of milk, of which 96.60% was distributed among hospitalised infants. Additionally, breastmilk from donor candidates (139 samples from 96 women) was tested at least once in the first year of lactation. First analyses showed that 18 women's milk samples were microbiologically pure, and 78 samples had one or more species of commensal and/or potentially pathogenic bacteria. In human milk samples from 10 women, the bacteria level was above the standard required by the RHMB; therefore, donors were re-educated, and further samples were tested. Most women followed the recommendations on hygienic expression and storage of milk before transfer to the RHMB. Our analysis will help to increase the accessibility and quality of raw donor milk and to meet the needs of more newborns.

Simulated dynamic digestion reveals different peptide releases from human milk processed by means of holder or high temperature-short time pasteurization.

High Temperature-Short Time (HTST) pasteurization was proposed as an alternative to Holder pasteurization (HOP) to increase the retention of specific human milk (HM) bioactive proteins. The present study explored whether HTST and HOP differently affect peptide release during simulated preterm infant gastrointestinal digestion. Raw (RHM), HOP- and HTST- pasteurized HM were digested using an in vitro dynamic system, and the identified peptides were analyzed by mass spectrometry and multivariate statistics. Before digestion, 158 peptides were identified in either RHM, HTST- or HOP- HM, mostly (84.4%) originating from ß-casein (CASB). During gastric digestion, HOP-HM presented a greater number and more abundant specific CASB peptides. A delayed release of peptides was observed in RHM during the intestinal phase, with respect to both pasteurized HM. Although limited to gastric digestion, the HM peptidomic profile differed according to the pasteurization type, and the pattern of the HTST peptides showed a greater similarity with RHM.

Problems and future development of human milk bank in China / 中华围产医学杂志

Human milk has its unique nutritional and immunological activities. Donor human milk, as the best alternative to breast milk, plays an important role in the rescue and treatment of premature and critically ill infants. This paper elaborates on the current situation, problems, and future development of human milk bank in China, and proposes to build a breast milk banking model based on local situation, establish evaluation standards, strengthen government supervision, set the charging standard based on the costs, and conduct research related to human milk bank, so as to improve the breastfeeding rate of critically ill and premature infants and reduce their mortality rate.

The Current State of Donor Human Milk Use and Practice.

Human milk contains nutrients and immune factors that promote health and growth of an infant. Donor human milk is recommended as the best alternative for infants whose mothers' breast milk is unavailable. This article describes the current status of donor human milk practice and suggests the areas of educational and research needs. Articles published in the last 10 years were reviewed, and findings were summarized under 4 themes: (1) women's knowledge and concerns about donor human milk use, (2) hospital practices, (3) cost-effectiveness, and (4) access and affordability of donor human milk. Women were concerned about donor human milk contamination, disease transmission, cost, and access to bank donor human milk, due to lack of knowledge and awareness of donor human milk benefits and its processing procedures. The absence of health care providers' support for donor human milk adds to the confusion. There is a rising trend of donor human milk use in hospitals for both healthy and vulnerable newborns and infants with varying policies on screening for donor human milk use, cost coverage, or consent procedure. However, a shortage of safe and affordable donor human milk is a barrier to its adoption. A standardized guideline is needed for hospitals regarding donor human milk implementation and cost coverage. Education programs for health care providers are needed to improve knowledge and understanding of donor human milk benefits and safety to provide guidance to parents. It is crucial to develop legislation expanding insurance coverage to achieve donor human milk equity and optimizing long-term human milk diet outcomes.

Clinical Results of the Implementation of a Breast Milk Bank in Premature Infants (under 37 Weeks) at the Hospital Universitario del Valle 2018-2020.

Breast milk is widely recognized as the best source of nutrition for both full term and premature babies. We aimed to identify clinical results of the implementation of a breast milk bank for premature infants under 37 weeks in a level III hospital. 722 neonates under 37 weeks, hospitalized in the Neonatal intensive care unit (ICU), who received human breast milk from the institution's milk bank 57% (n = 412) vs. mixed or artificial 32% (n = 229), at day 7 of life. An exploratory data analysis was carried out. Measures of central tendency and dispersion were used, strength of association of odds ratio (OR) and its confidence intervals (95% confidence interval (CI)). 88.5% had already received human milk before day 7 of life. Those who received human milk, due to their clinical condition, had 4 times a greater chance of being intubated (OR 4.05; 95% CI 1.80-9.11). Starting before day 7 of life decreases the opportunity to develop necrotizing enterocolitis by 82% (adjusted odds ratio (ORa) 0.18; 95% CI 0.03-0.97), intraventricular hemorrhage by 85% (ORa 0.15; 95% CI 0.06-0.45) and sepsis by 77% (ORa 0.23; 95% CI 0.15-0.33). Receiving human milk reduces the probability of complications related to prematurity, evidencing the importance that breast milk banks play in clinical practice.

The impact of the Covid-19 pandemic on North American milk banks.

This study aims to understand the impact of the Covid-19 pandemic on human milk banking services in North America, with a focus on the United States. We triangulated questionnaire data with interviews and text-based website data. Of the 30 human milk bank services from which data were obtained, the majority faced substantial internal organization change in terms of staffing and protocols and experienced financial hardship in particular because of decreases in donor human milk orders. At the same time, most banks reported an increase in their numbers of donors and in the volume of milk collected. These results show that the pandemic significantly affected the way in which many North American milk banks operate, some lactating mothers donate their milk and, at least during the first few months of the crisis, certain hospitals' donor human milk ordering patterns changed. It suggests in particular that stay-at-home orders and the turn to remote work created the potential for a surge in human milk available for donation as a number of parents no longer needed their surplus for their own children. Legal and policy reform should focus on replicating the positive effects of the pandemic on breastfeeding by guaranteeing paid parental leave and flexible work conditions. Initiatives should also aim at counteracting its negative effects by mandating the insurance coverage of donor human milk, supporting milk banks financially and, more generally, integrating lactation and human milk banking services within the health system.

Role of human milk banks amid COVID 19: perspective from a milk bank in India.

The COVID-19 pandemic has had a significant impact on the operation of donor human milk banks in various countries such as China, Italy and India. It is understandable that this impact on operations of donor human milk might hamper the capability of these milk banks to provide sufficient pasteurized donor milk to neonates who need it. Contrary to developed world, predominant donors in developing nations are mothers of hospitalised neonates who have a relatively long period of hospital stay. This longer maternal hospital stay enhances the feasibility of milk donation by providing mothers with access to breast pumps to express their milk. Any excess milk a mother expresses which is above the needs of their own infant can be voluntarily donated. This physical proximity of milk banks to donors may help continuation of human milk donation in developing nations during the pandemic. Nevertheless, protocols need to be implemented to i) ensure the microbiological quality of the milk collected and ii) consider steps to mitigate potential consequences related to the possibility of the donor being an asymptomatic carrier of COVID-19. We present the procedural modifications implemented at the Comprehensive Lactation Management Centre at Lady Hardinge Medical College in India to promote breastfeeding and human milk donation during the pandemic which comply with International and National guidelines. This commentary provides a perspective from a milk bank in India which might differ from the perspective of the international donor human milk banking societies.

The Impact of Human Milk on Necrotizing Enterocolitis: A Systematic Review and Meta-Analysis.

BACKGROUND: Premature infants receiving breastfeed have a lower incidence of NEC than those fed preterm formula. This study aimed: (1) to update a systematic review and meta-analyses to evaluate the relationship between feeding and necrotizing enterocolitis (NEC) in low weight premature infants; (2) to conduct meta-regression analyses by subgroups; (3) to describe geographical distribution of milk banks in the world. METHODS: Papers included in the meta-analysis were updated as of June 2019. Relative risks were used as a measure of effect size. Random effect models were used to account for different sources of variation among studies. For milk banks, the data reviewed by the literature were integrated with the information collected from countries' institutional sites and milk bank networks. RESULTS: Thirty-two papers were included in meta-analysis: six randomized controlled trials (RCTs) and 26 observational studies (OS). The census has found 572 milk banks around in the world. Brazil has the most active milk banks. RCTs meta-analysis indicates a risk reduction of NEC using human milk respect to formula: Relative risk (RR) = 0.62 (0.42-0.93). Seven OS compared quantities lower than human milk or higher than the 50th quantile showing a risk reduction of NEC:RR = 0.51 (0.31-0.85); 3 OS that evaluated human milk versus mixed feeding showing that human milk has a protective role on the development of NEC:RR = 0.74 (0.63-0.91). Results of subgroups analysis show that the risk reduction is statistically significant only for studies in which premature infants are given both their own and donated breastmilk. CONCLUSIONS: The possibility of preserving human milk and promoting donations guarantees an improvement in the health of newborns.

ABSTRACT Objective To evaluate the association between maternal characteristics and assistance services provided by a Human Milk Bank (HMB) to women in the puerperal period and their hospitalized newborns. Methods A quantitative cross-sectional study conducted at a public maternity in southern Brazil between July and December of 2017. It was used a structured form for data collection. The statistical analysis was conducted using Chi-Square for association or Fisher's Exact test. Results In total, 316 mothers were part of this study. The main reasons were weight loss of the newborn and difficulty in handling. Statistically significant associations were found between follow up services from HMB and mother's age (18-23 years old: 58.1%; 24-29: 63.8%; 30-35: 78.9%; 36-41: 71.8%, and 42-47: 85.7%; p = 0.036), mother's race/color (brown: 47.2%; white: 68.9%; black: 77.8%; p = 0.031), and type of delivery (normal: 61,0%; caesarean section: 75.2%; p = 0.011). Conclusion and implications for practice Mothers of older age, who were black and with children born by cesarean section were the ones who sought more often and had most follow-ups at the HMB of the maternity. The results found may contribute to the planning, monitoring and elaboration of strategies for breastfeeding actions.

A clinical audit of the growth of preterm infants fed predominantly pasteurised donor human milk v. those fed mother's own milk in the neonatal intensive care unit.

Preterm infants whose mothers are unable to produce sufficient breast milk are increasingly being supplemented with pasteurised donor human milk (PDHM) instead of commercial preterm infant formula. Concerns have been raised that this practice can result in reduced growth. This retrospective clinical audit collected data from the medical records of a cohort of preterm infants (≤30 weeks gestational age) receiving either ≥28 d of PDHM (n 53) or ≥28 d of their mother's own milk (MOM, n 43) with standard fortification supplied to both groups during admission. Weight growth velocity was assessed from regained birth weight to 34+1 weeks' postmenstrual age (PMA); and weight, length and head circumference were compared at discharge and 12 months (corrected age). At 34+1 weeks' PMA, the weight growth velocity (g/kg per d) was significantly lower in the PDHM group (15·4 g/kg per d, 95 % CI 14·6, 16·1) compared with the MOM group (16·9 g/kg per d, 95 % CI 16·1, 17·7, P=0·007). However, the increase was still within clinically acceptable limits (>15 g/kg per d) and no significant difference was observed in the weight between the two groups. There was no significant difference in weight between the groups at discharge or at the 12-month corrected gestational age review. Although we demonstrated a significant reduction in the weight growth velocity of preterm infants receiving PDHM at 34 weeks' PMA, this difference is not present at discharge, suggesting that the growth deficit is reduced by supplementation before discharge.
