Methods of milk expression for lactating women

Relaxation Therapy and Human Milk Feeding Outcomes: A Systematic Review and Meta-Analysis

Importance

Human milk feeding is a key public health goal to optimize infant and maternal/parental health, but global lactation outcomes do not meet recommended duration and exclusivity. There are connections between lactation and mental health.

Objective

To appraise all available evidence on whether the provision of relaxation interventions to lactating individuals improves lactation and well-being.

Data Sources

Embase, MEDLINE, CINAHL, Allied and Complementary Medicine Database, Web of Science, and the Cochrane Library were searched on September 30, 2023, and topic experts were consulted.

Study Selection

Two independent reviewers screened for eligibility. Inclusion criteria were full-text, peer-reviewed publications with a randomized clinical trial design. Techniques that were entirely physical (eg, massage) were excluded. A total of 7% of initially identified studies met selection criteria.

Data Extraction and Synthesis

Two independent reviewers extracted data and assessed risk of bias with the Cochrane Risk of Bias 2 tool. Fixed-effects meta-analysis and Grading of Recommendations, Assessment, Development, and Evaluations guidelines were used to synthesize and present evidence.

Main Outcomes and Measures

Prespecified primary outcomes were human milk quantity, length and exclusivity of human milk feeding, milk macronutrients/cortisol, and infant growth and behavior.

Results

A total of 16 studies were included with 1871 participants (pooled mean [SD] age for 1656 participants, 29.6 [6.1] years). Interventions were music, guided relaxation, mindfulness, and breathing exercises/muscle relaxation. Provision of relaxation was not associated with a change in human milk protein (mean difference [MD], 0 g/100 mL; 95% CI, 0; 205 participants). Provision of relaxation was associated with an increase in human milk quantity (standardized mean difference [SMD], 0.73; 95% CI, 0.57-0.89; 464 participants), increased infant weight gain in breastfeeding infants (MD, z score change = 0.51; 95% CI, 0.30-0.72; 226 participants), and a slight reduction in stress and anxiety (SMD stress score, -0.49; 95% CI, -0.70 to -0.27; 355 participants; SMD anxiety score, -0.45; 95% CI, -0.67 to -0.22; 410 participants).

Conclusions and Relevance

Results of this systematic review and meta-analysis suggest that provision of relaxation was associated with an increase in human milk quantity and infant weight gain and a slight reduction in stress and anxiety. Relaxation interventions can be offered to lactating parents who would like to increase well-being and improve milk supply or, where directly breastfeeding, increase infant weight gain.

Effect of Lactation Management Model on Breastfeeding Process After Cesarean: A Prospective Randomized Controlled Study

It is important to implement supportive programs to ensure mothers breast feed for the desired period, and infants are fed by only mother's milk. In the research, it was aimed at evaluating the effects of lactation management model on mothers' breastfeeding process following a caesarean section. Women who gave birth by planned cesarean delivery were divided into two groups, randomized control and experimental. Data collection was performed during gestation, first day after postpartum, pre-discharge, on the 9th day in a face to face interview, and in the form of monthly phone interviews up to 6 months. While the experimental group exercised the lactation management model, the control group received routine lactation practices in clinic. In the scores of Breastfeeding Charting System and Documentation Tool, a significant difference was found between the groups (p<0.001). 87.9% of the experimental group and 48.5% of the control group were determined to apply successful breast-feeding techniques. In addition, it was found that all of the experimental group breast fed 1 month longer than the control group, and for the first month, 90.9% of the experimental group and 78.8% of the control group breast fed with mother's milk only and a higher breastfeeding. Among in the experimental group, it was found that breastfeeding self-efficacy was higher, and breastfeeding techniques were accurate and successful and breastfeeding only and continuity rates were higher while breastfeeding related breast problems developed less frequently.

Maternal diet and human milk composition: an updated systematic review

Context

Exclusive breastfeeding for 6 months after birth provides infants with the best start for life. A review by Bravi et al. summarized the importance of maternal diet as a determinant of human milk composition based on data up to 2015, but evidence on nutrient intake level was limited.

Objective

We updated the review by Bravi et al., critically assessed differences in study designs and sampling methods, and graphically visualized trends and associations.

Data sources

PubMed was systematically searched for articles published between January 2015 and March 2021.

Data extraction

Article screening, selection, and data extraction was done by two independent researchers, including a risk of bias assessment based on 11 criteria. Articles were eligible when including: quantitative information, commonly used effect estimates, healthy mother-infant dyads.

Results

Twenty seven observational and five intervention studies were identified (n = 7,138) and combined with results of Bravi et al. Fatty acids were still the most studied human milk components in relation to maternal diet (n = 17 studies) with maternal fish intake being predominantly positively associated with milk ALA (r = 0.28-0.42), DHA (r = 0.24-0.46), and EPA (r = 0.25-0.28) content. PUFAs from diet were generally positively correlated with their concentrations in milk, while SFA intake was negatively associated with several fatty acids in milk. Studies on associations with maternal diet and milk carbohydrates, proteins, vitamins and minerals were limited in number and varied in methods and results.

Conclusion

This updated review shows that evidence on the association between maternal diet and human milk fatty acids is rapidly increasing, but still diversified in methodology and results. Further studies, preferably intervention studies, assessing diet and milk carbohydrates, proteins, vitamins and minerals are needed to be able draw conclusions on the importance of maternal diet for human milk composition as a whole.

Predicting Chemotherapy Distribution into Breast Milk for Breastfeeding Women Using a Population Pharmacokinetic Approach

BACKGROUND AND OBJECTIVE

Information on the distribution of chemotherapeutic drugs to breast milk is scarce, and reports are limited to small sample sizes. Anecdotal pharmacokinetic data have typically been acquired from lactating but non-breastfeeding patients who collect breast milk by means of an expression pump, which might not necessarily be representative for a breastfeeding population due to differences in milk production. Consequently, little is known about the variability of chemotherapy distribution to breast milk and the effect of milk production on the distribution of chemotherapy to breast milk. Our aim was to predict chemotherapy distribution to breast milk in a more realistic breastfeeding population and evaluate the effect of discarding breast milk on the potential chemotherapy exposure in infants.

METHODS

We developed a population pharmacokinetic model that described the breast milk production and the chemotherapy distribution to breast milk of a non-breastfeeding population, linked it to plasma pharmacokinetics, and extrapolated this to a breastfeeding population.

RESULTS

We found that cumulative relative infant doses (RID) were higher than 10% for cyclophosphamide and doxorubicin and approximately 1% for paclitaxel. Simulations allowed us to predict the cumulative RID and its variability in the population for patients with different milk productions and the amount of breast milk that has to be discarded to reach cumulative RIDs below 1%, 0.1%, and 0.01%. Discarding 1-2, 3-6, and 0-1 days of breast milk (depending on the milk production of the patient) resulted in cumulative RID below 1% for cyclophosphamide, doxorubicin, and paclitaxel, respectively.

CONCLUSION

Our results may help clinicians to derive the optimal breast milk discarding strategy for an individual patient that wants to breastfeed during chemotherapy and minimize chemotherapy exposure in their infants.

Efficacy and safety of acupuncture for postpartum hypogalactia: protocol for a systematic review and meta-analysis

INTRODUCTION

Breast milk is recognised as the best natural food for neonates, but many women experience postpartum hypogalactia (PH). Randomised trials have found that acupuncture exert therapeutic effect on women with PH. However, systematic reviews on the efficacy and safety of acupuncture are still lacking; therefore, this systematic review aims to evaluate the efficacy and safety of acupuncture for PH.

METHODS AND ANALYSIS

Six English databases (PubMed, Cochrane Library, EMBASE, EBSCO, Scopus, and Web of Science) and four Chinese databases (China National Knowledge Infrastructure, Wan-Fang, Chinese Biomedical Literature and Chinese Scientific Journal) will be systematically searched from their establishment to 1 September 2022. Randomised controlled trials of the efficacy of acupuncture for PH will be reviewed. The study selection, data extraction and research quality evaluation will be conducted independently by two reviewers. The primary outcome is the change in serum prolactin level from baseline to the end of treatment. Secondary results include milk secretion volume, total effectiveness rate, degree of mammary fullness, rate of exclusive breast feeding, and adverse events. A meta-analysis will be performed using RevMan V.5.4 statistical software. Otherwise, a descriptive analysis will be conducted. The risk of bias will be assessed using the revised Cochrane risk-of-bias tool.

ETHICS AND DISSEMINATION

This systematic review protocol does not require ethical approval because it does not include private information/data of the participants. This article will be published in peer-reviewed journals.

Factors Associated with an Inadequate Volume of Expressed Milk Among Mothers of Preterm and Low Birth Weight Neonates Admitted to Neonatal Intensive Care Units of Government Hospitals in Addis Ababa, Ethiopia

Background

Around 15 million live newborns are born prematurely each year around the world before 37 weeks. One cause of inadequate nursing is prematurity. The goal of this study was to find parameters linked to an insufficient volume of expressed milk among mothers of preterm and low birth weight neonates at government hospitals in Addis Ababa, Ethiopia.

Methods

An nstitution-based cross-sectional study was conducted on a total of 124 mothers who were available in neonatal intensive care units during the study period in government hospitals that provided such units.

Results

One-third of the responders (33.9%) were unable to express the necessary amount of milk. An inadequate volume of expressed breast milk was significantly associated with a baby's stable health status (AOR=0.24; CI=0.07-0.86), the fair (subcritical) health status of the baby (AOR=0.178; CI=0.04-0.76), worry about the volume of milk (AOR=7.50; CI=3.32-16.95), and worry about the baby's health status (AOR=4.63; CI=2.21-9.70).

Conclusion

According to our findings, 33.9% of mothers were unable to express sufficient amounts of milk. To produce an adequate volume of expressed breast milk, health care workers must address mothers' psychological issues in the neonatal intensive care units and give all necessary care to prevent neonatal deterioration.

Evaluating the Challenges and Potential Complications of Breastfeeding in Naval Aviation

INTRODUCTION

Active duty flight crew plays a critical role in military operations. The occupational demands of the flying environment require a certain level of medical suitability. Additionally, such an environment could be more hazardous for certain populations. While the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the World Health Organization strongly support exclusive breastfeeding for the health benefit of both the mother and the child in the first 6 months of life, the aeromedical implications of lactating are not widely discussed. Breastfeeding is inherently challenging for many women, in part because of the frequent emptying required to maintain breastmilk supply and avoid complications such as engorgement, clogged ducts, and mastitis. This pilot study evaluated the experiences of individuals concurrently breastfeeding while on active duty Naval flying status to (1) assess whether these individuals experience frequent challenges or complications associated with lactating and (2) establish the need for future expanded studies.

MATERIALS AND METHODS

This survey-based, retrospective, descriptive study evaluated the experiences of 17 lactating individuals on active duty Naval flying status. Women were recruited using word of mouth and social media platforms. Responses were tabulated and summarized from the survey, which included yes/no questions and free-response sections regarding flying position, breastfeeding history, and breastfeeding challenges. This trial was approved by the Naval Air Warfare Center Aircraft Division (NAWCAD) Institutional Review Board (Protocol Number NAWCAD.2021.0004-IR-EP7).

RESULTS

Of the 27 women who received study materials after expression of interest, 17 individuals completed the informed consent and survey protocols. Although limited by sample size and the demographics of respondents, the results highlight that the active duty flying environment did impact the breastfeeding experiences of the participants, with 88% of respondents reporting some difficulty or complication associated with breastfeeding and the operational flying environment. Difficulty in maintaining breastmilk supply, engorgement, and the need for supplementation were some of the concerns discussed.

CONCLUSIONS

This study hypothesizes that occupational demands associated with aviation result in a decreased ability to maintain exclusive breastfeeding, an increased risk for engorgement and clogged ducts, and a higher likelihood of early weaning among Naval aviators. It included only the perspectives of Naval officers, thereby lacking the input of enlisted aircrew on flight status, who comprise a large population of active duty flyers. The responses, although limited by a lack of controls and survey limitations, indicate that a future study to expand understanding of the aeromedical implications on lactating individuals would be valuable for improving workplace support and the ultimate success of lactating women in meeting their breastfeeding goals.

Initiating and Supporting Breastfeeding: Guidelines for Interventions during the Perinatal Period from the French National College of Midwives

Exclusive breastfeeding is recommended for children for the first 4 to 6 months of life, with complementary foods added thereafter. It is the most ecological way of protecting the child's and mother's health. Training of health professionals is required to avoid transmitting inconsistent information in 3 areas: 1) implementing these 3 predictors: safe skin-to-skin, first breastfeed, and rooming-in 24/7; 2) teaching and monitoring: i) early signs of waking and feeding rhythms, ii) positioning and latching, and iii) signs of effective transfer; and 3) referring women to specialized support services if difficulties arise (eg, inadequate milk production, pain, cracked nipples, engorgement). Breastfeeding should continue during mastitis or an abscess. Ultrasound-guided needle aspiration is beneficial in treating an abscess. Précis: Information is provided to enable health professionals to better support breastfeeding and help women with the most common difficulties, thus promoting breastfeeding initiation and duration.

Effect of lullaby on volume, fat, total protein and albumin concentration of breast milk in premature infants' mothers admitted to NICU: a randomized controlled trial

Background

Listening to music can reduce or manage stress, fatigue, and accompanying symptoms in mothers. Music increases oxytocin secretion which affects breast milk. This study aimed to examine the effect of lullaby on volume, fat, total protein and albumin concentration of breast milk in mothers of premature infants admitted to the NICU.

Methods

This clinical trial was performed on 100 primiparous mothers whose premature infants were hospitalized in the NICU of Ayatollah Rouhani Hospital from January 2020 to December 2020. Using block randomization method, the participants were divided into three groups: control (A), playing lullaby for mother (B) and playing lullaby for a mother while holding a photo of her own baby (C). The mothers of the intervention groups listened to lullabies through headphones for 30 minutes every morning for 6 days. On the first and the sixth day of birth, the volume of breast milk (ml) and two milliliters of breast milk samples of all three groups were measured and compared in terms of fat, albumin concentration and total protein (mg/DL). ANOVA, Paired T-Test and ANCOVA model (the included variables were: basic value of dependent variable, group type, Maternal age, Birth weight, Gestational age and Maternal weight) was used for analytical statistics.

Results

The difference between the mean compositions of breast milk before and after the intervention in three groups of A, B and C: in terms of the breast milk volume were 66.33 ± 4.80, 71.30 ± 4.18 and 75.91 ± 6.80 ml; in terms of triglyceride level was 177.84 ± 50.57, 210.72 ± 34.55 and 224.17 ± 12.97 mg/DL, cholesterol level was 14.57 ± 3.70, 21.96 ± 3.82 and 26.26 ± 5.16 mg/DL, albumin concentration was 0.90 ± 0.30, 1.22 ± 0.19 and 1.46 ± 0.28 mg/DL and total protein level was 1.61 ± 0.61, 2.20 ± 0.57 and 2.72 ± 0.30 mg/DL. Finally, the results of ANCOVA analysis for the effects of the intervention, taking into account the baseline values, showed that the intervention was effective and had the greatest effect on cholesterol levels.

Conclusion

In this small trial, there was a statistically significant association between trial arm and biochemical composition of breastmilk though further studies are needed to see if these changes result in meaningful clinical outcomes to the infant.

Comparing the effect of a lactation-specific relaxation and visualisation intervention versus standard care on lactation and mental health outcomes in mothers of very premature infants (the EXPRESS trial): study protocol for a multi-centre, unmasked, randomised, parallel-group trial

Background

Premature birth is the leading cause of neonatal death and can cause major morbidity. Maximising the amount of maternal breastmilk given to very premature infants is important to improve outcomes, but this can be challenging for parents. Parents of infants receiving neonatal care also have high rates of anxiety and distress. There is growing evidence for the impact of maternal relaxation interventions on lactation, as well as mental health. The trial will assess whether a brief self-directed relaxation and visualisation intervention, recommended for use several times a day during expression of milk, improves lactation and mental health outcomes for mothers of very premature infants.

Methods

Multi-centre, randomised, controlled, unmasked, parallel-group trial with planned 132 participants who have experienced premature birth between 23 weeks and 31 weeks and 6 days of gestation and plan to express milk for at least 14 days. The primary outcome is the highest 24-h expressed milk yield recorded on any of day 4, day 14 or day 21 after birth. Secondary outcomes include exclusive breastmilk feeding at 36 weeks post-menstrual age and at 4 months after the estimated date of delivery, Spielberger State Trait Anxiety Index at day 21 and Post-traumatic stress Check List (for DSM 5) at day 21.

Discussion

Breastmilk feeding for premature infants is an important research priority, but there are few randomised controlled trials assessing interventions to help parents reach lactation goals in this challenging context. This trial will assess whether a no cost, easily scalable relaxation tool has a role in this setting. Given the lack of harm and potential for immediate dissemination, even a small benefit could have an important global impact.

Changes in Human Milk Fat Globule Composition Throughout Lactation: A Review

There has been a growing interest in understanding how the relative levels of human milk fat globule (MFG) components change over the course of lactation, how they differ between populations, and implications of these changes for the health of the infant. In this article, we describe studies published over the last 30 years which have investigated components of the MFG in term milk, focusing on changes over the course of lactation and highlighting infant and maternal factors that may influence these changes. We then consider how the potential health benefits of some of the milk fat globule membrane (MFGM) components and derived ingredients relate to compositional and functional aspects and how these change throughout lactation. The results show that the concentrations of phospholipids, gangliosides, cholesterol, fatty acids and proteins vary throughout lactation, and such changes are likely to reflect the changing requirements of the growing infant. There is a lack of consistent trends for changes in phospholipids and gangliosides across lactation which may reflect different methodological approaches. Other factors such as maternal diet and geographical location have been shown to influence human MFGM composition. The majority of research on the health benefits of MFGM have been conducted using MFGM ingredients derived from bovine milk, and using animal models which have clearly demonstrated the role of the MFGM in supporting cognitive and immune health of infants at different stages of growth and development.

A Comparison of the Timing of Hand Expressing of Human Milk With Breast Massage to Standard Care for Mothers of Preterm Infants: An Exploratory Pilot Using a Randomized Controlled Design

BACKGROUND

Globally, 10% of all births are preterm. Access to human milk via manual breast expression is required to reduce the incidence of adverse outcomes related to prematurity. However, there is little evidence to recommend optimum timing to commence breast expression in mothers of preterm infants or the most effective method.

RESEARCH AIMS

(1) To test feasibility of recruitment and compliance to the protocol and (2) to determine influence of using hand expressing and breast massage on milk production, engorgement, mastitis, and breastfeeding status at 3 months.

METHODS

This study was an exploratory parallel two-group, pilot randomized controlled trial. Mothers of preterm infants at a metropolitan maternity hospital in Queensland Australia (N = 31) were randomized to receive either hand expressing and breast massage within the 1st hr of birth or standard care, hand expressing within 6 hr of birth, to determine the influence on milk production, engorgement, mastitis, and breastfeeding status at 3 months.

RESULTS

Feasibility targets were not met; however, valuable learning from this trial uncovered barriers facing midwives in the birth suite to commencing expressing in the 1st hr of birth. There was no difference in occurrence of secondary outcomes, although trends support future study.

CONCLUSIONS

Overall, unpredictability of preterm birth influenced our ability to recruit participants. Important directions for future study design would benefit from incorporating expressing times up to 6 hr with a replicable breast massage.

'Is there any point in me doing this?' Views and experiences of women in the Diabetes and Antenatal Milk Expressing (DAME) trial

The Diabetes and Antenatal Milk Expressing (DAME) randomised controlled trial (RCT) was conducted in 2011–2015, at six sites in Melbourne, Australia to explore the effect of advising women with diabetes in pregnancy to express breast milk from 36 weeks gestation. Infants whose mothers were randomised to express in pregnancy were more likely to be exclusively breast milk fed during their hospital stay, and there was no evidence of harm. This paper explores women's views and experiences of antenatal expressing. In this two‐arm RCT, 635 women with diabetes in pregnancy who were otherwise of low medical risk were randomised at 36–37 weeks gestation to usual care (not expressing, n = 316), or the intervention, where women were advised to hand express for 10 min twice daily until birth (n = 319). Semistructured face‐to‐face interviews were conducted with 10 women who expressed antenatally. They were asked about their experiences of antenatal expressing, including how they felt about the overall experience, the amount of breast milk they expressed, making time to express, and their experience of breastfeeding. Thematic analysis of the in‐depth interviews identified six themes: (1) learning and adapting expressing, (2) feelings and sensations associated with expressing, (3) support, (4) dis/empowerment, (5) health, and (6) the value of breast milk. Women had both positive and negative experiences of antenatal expressing. If health professionals are advising antenatal expressing to women, it is important they understand the range of outcomes and experiences.

Women's experiences of antenatal expressing were both positive and negative; it is important to understand the range of experiences.

Women should be advised that some women express little or no breast milk antenatally and therefore be reassured if they are concerned.

For women with diabetes in pregnancy, their diabetes management is a significant time burden, and should be considered when discussing antenatal expressing with women.

Maternity care providers need to follow‐up with pregnant women advised to express, to provide education, reassurance, and reassess expressing techniques.

Maternity care providers need to manage and prioritise the use of expressed breast milk.

Initiation of lactation and the provision of human milk to preterm infants in German neonatal intensive care units from the mothers' perspective

Background

If infants with a very low birth weight (VLBW) are to be fed exclusively with human milk, it is essential to focus on lactation initiation. The aim of the study is to learn more about the current state of lactation initiation and human milk provision in neonatal intensive care units in Germany from the mothers' perspective.

Methods

Written surveys were conducted with mothers of VLBW infants to learn more about the timing of initiation of lactation, pumping frequency during the first three days postpartum and feeding of the preterm infant during hospitalisation.

Results

The data of 437 mothers (response rate: 44.7%) were included in the analyses. Of these, only 7.8% stated that they had initiated lactation immediately after delivery and 38.2% within 6 h. In terms of pumping frequency, 50.1% pumped 7–9 times a day within the first 3 days postpartum; 60.9% reported that their infant received formula feedings during the hospital stay.

Conclusion

Overall, deficits were still evident with regard to the initiation of lactation in mothers of VLBW infants in Germany, resulting in a large proportion of VLBW infants receiving formula in the hospital.

Effects of a WeChat Mini-Program on Human Milk Feeding Rates in a Neonatal Intensive Care Unit During the COVID-19 Pandemic

OBJECTIVE

We investigated changes in maternal daily milk pumping frequency and milk volume per expression and their derived lactation indicators, as well as human milk (HM) feeding status with a focus on amount and rates in preterm infants admitted to the neonatal intensive care unit (NICU) after using a WeChat mini-program during the 2019 coronavirus (COVID-19) pandemic.

METHODS

The study was conducted with 482 mothers and their 544 babies. We prospectively enrolled mothers and infants with birth weight <1,500 g or gestational age <32 weeks born in 2020, and retrospectively included the same population in 2019. All study subjects were classified into three subgroups: pre-pandemic (PP, 2019), early pandemic (EP, January to April 2020), and late pandemic (LP, May to December 2020). From 1 January 2020, mothers recorded in an online pumping diary using the WeChat mini-program. We obtained the infants' feeding information from an online database for analysis.

RESULTS

Maternal lactation indicators did not change significantly. However, 56.7% (139/245) of mothers achieved milk volume ≥500 ml/day (CTV) in PP, 58.9% (33/156) in EP, and a slight increase to 60.7% (91/150) in LP. Maternal pumping frequency remained about eight times/day. In LP, daily milk volume was higher than the other two periods from day 4, and mothers achieved CTV by day 12, which was achieved in the other two groups by 13-14 days. There were several statistical differences in the amount and rates of feeding between the groups, particularly about HM and donor milk feeding, with the vast majority being decreased during EP, while during LP they returned to PP levels. Pleasingly, the median average daily dose of HM at 1-28 days was highest in LP (LP, 87.8 vs. PP, 75.5 or EP, 52.6 ml/kg/day, P _corrected < 0.001). In addition, most categorical feeding indicators decreased in EP and recovered in LP.

CONCLUSION

An education model based on the WeChat program could aid lactation education and management in mothers of preterm infants to maintain healthy lactation. The model, together with optimized management strategies, can ensure that the HM feeding rate is not compromised in vulnerable high-risk infants during NICU hospitalization in a public health emergency, like the COVID-19 pandemic.

In Vitro Flow Visualization in a Lactating Human Breast Model

Human milk extraction from the breast is affected by the infant's oral activities. Natural suckling by the infant includes both intraoral vacuum and peripheral oral compression during breastfeeding. However, the contribution of each of these motions to milk extraction at the outlet and at the duct bifurcations is unclear. In this work, we investigated the flow field in a lactating breast model considering bifurcated milk ducts and multiphase breast-infant interactions. A bio-inspired breastfeeding simulator device was utilized to mimic an infant's oral feeding mechanism during breastfeeding and extract the human milk-mimicking Fluid from the transparent and elastic lactating breast phantom during experiments. Using a particle image velocimetry system, we found that the oscillatory flow under vacuum pressure provides a higher velocity field at the outlet compared to that when an infant applies both vacuum and oral compression pressures. Additionally, the intraoral vacuum coordinated with the oral peripheral compression causes stronger vorticities and secondary flows at the adjunction of the bifurcated ducts than the vacuum-only case. Vacuum-only extraction yields an increase in flow velocity at the outlet and could be one of the reasons for nipple pain, whereas infant's oral activities on the breast generated more vortices in the milk duct adjunctions and might cause milk duct clogs. This phenomenon is rationalized based on the validation of a previous in vivo clinical study of milk production compared between commercial pumps and infant suckling. The fact that milk consumption of vacuum-only extraction is less than that of vacuum plus oral compression further explains the effectiveness of applying a natural suckling pattern in human lactation.

Surveying family access: kangaroo mother care and breastfeeding policies across NICUs in Italy

BACKGROUND

Studies on the application of developmental care initiatives in Italian NICUs are rather scarce. We aimed to assess parental access to the NICUs and facilities offered to the family members and to test "the state of art" regarding kangaroo mother care (KMC) and breastfeeding policies in level III Italian NICUs.

METHODS

A questionnaire both in paper and in electronic format was sent to all 106 Italian level III NICUs; 86 NICUs (i.e., 80% of NICUs) were completed and returned. The collected data were analysed. In addition, a comparison between the 2017 survey results and those of two previous surveys conducted from 2001 to 2006 was performed.

RESULTS

In total, 53 NICUs (62%) reported 24-h open access for both parents (vs. 35% in 2001 and 32% in 2006). Parents were requested to temporarily leave the unit during shift changes, emergencies and medical rounds in 55 NICUs (64%). Some parental amenities, such as an armchair next to the crib (81 units (94%)), a room for pumping milk and a waiting room, were common, but others, such as family rooms (19 units (22%)) and adjoining accommodation (30 units (35%)), were not. KMC was practised in 81 (94%) units, but in 72 (62%), i.e., the majority of units, KMC was limited to specific times. In 11 (13%) NICUs, KMC was not offered to the father. The average duration of a KMC session, based on unit staff estimation, was longer in 24-h access NICUs than in limited-access NICUs. KMC documentation in medical records was reported in only 59% of questionnaires. Breastfeeding was successful in a small proportion of preterm infants staying in the NICU.

CONCLUSION

The number of 24-h access NICUs doubled over a period of 13 years. Some basic family facilities, such as a dedicated kitchen, rooms with dedicated beds and showers for the parents, remain uncommon. KMC and breastfeeding have become routine practices; however, the frequency and duration of KMC sessions reported by NICU professionals still do not meet the WHO recommendations.

Developing global guidance on human milk banking

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.

Advice from Canadian Mothers Who Express Human Milk: An Interpretive Description Qualitative Study

OBJECTIVES

Human milk expression has become an increasingly common means for providing milk to an infant, with women expressing to address breastfeeding problems or to allow for flexible feeding options. This study explored the experiences and recommendations of mothers who expressed human milk, with this paper reporting on the advice mothers would offer to other mothers to address common challenges.

METHODS

Interpretive description was used in this qualitative project. Using purposive sampling, mothers of infants aged 0-24 months who expressed human milk were recruited to participate from two health regions in western Canada. Individual, audio-taped interviews were completed with 35 women. NVIVO™ software was used for data analysis.

RESULTS

Mothers reported the desire to offer experiential advice to other mothers navigating milk expression and encouraged other mothers to seek guidance from health care professionals such as lactation consultants, peer support online, and from family and friends. Experiential knowledge shared included: (a) product recommendations, (b) expression tips, (c) support for workplace expression, (d) encouragement to seek help, and (e) moral support.

CONCLUSIONS

Healthcare professionals should include evidence-based expression information as part of routine lactation support, while recognizing the importance of mother-to-mother knowledge transfer and emotional support. Services that assist mothers to determine and access pumps appropriate to their unique breastfeeding needs and goals should be offered, and the opportunity for peer support through creation of, or referral to, appropriate in-person or online support groups should be made available.

Measuring Mothers' Viewpoints of Breast Pump Usage

Breastfeeding has short- and long-term positive influences on the health and wellbeing of the child. There are situations where breastfeeding does not occur and expressed or pumped mother's milk is used. Mothers and healthcare providers report problems or negative views on using pumps in studies across the globe. This systematic review and secondary analysis of 18 random control trials related to mothers' views of breast pumps examines the range of viewpoints gathered, the variety of measurement instruments used, how the outcomes are reported and the challenges that occur. It aims to inform critical reading of research as well as future research design. Devices which the mother views as comfortable and useful will facilitate more infants to receive human milk when direct breastfeeding does not occur, and they will have a positive influence on health and wellbeing.

Telelactation with a Mobile App: User Profile and Most Common Queries

Background: Mobile applications related to health issues are currently expanding. Different uses of new technologies have produced positive results regarding breastfeeding support. Breastfeeding applications are increasing. Objective: We conducted a descriptive analysis of a mobile application for breastfeeding (LactApp) to study the user profile and the most frequent queries. Materials and Methods: This was a retrospective, comparative, and descriptive ecological time-series study of LactApp from 2016 to 2019. Google Analytics and the app itself were used for data collection. The data were analyzed in Excel, and for the time series, Prais-Winsten autoregressions were applied based on the Durbin-Watson method in Stata. Results: A total of 115,830 users and 71,780 infants were registered in the application. A total of 1.91% of these users obtained the medical version. The application was used for both queries and surveys and for users to interact through chat. A total of 30.17% of the responses were related with "baby's sleep" (8.94%), 8.91% were related to "preservation of milk," 6.16% were related to "breastfeeding crisis," and 6.15% were related to "physiological evolution of breastfeeding," all with an increasing trend. Conclusion: LactApp is a resource for breastfeeding that is widely downloaded and used by a substantial number of individuals. The most recurring topics were baby's sleep, milk extraction and preservation, breastfeeding crisis and physiological evolution of breastfeeding.

Chlorine Solutions for a Safe Method of Decontamination of Breast Pump Milk Collection Kits Before and After the Coronavirus Disease 2019 Pandemic

To promote breast feeding and breast pumping is essential for the most vulnerable infants even if the current coronavirus disease 2019 (COVID-19) pandemic sanitary crisis imposes more stringent hygienic measures. As recommended by the Centers for Disease Control and Prevention, World Health Organization, and Milk Bank Association, "after each pumping session, all pump part that come into contact with breast milk should be appropriately disinfected." The present study proposed different methods than can be used and focus on the safety analysis of chlorine solution (CS) in terms of residual hypochlorous acid (HCA) and total trihalomethanes (THM). We also performed an efficacy testing of the CS approach to decontaminate the devices used to collect the milk (breast pumps and bottles). The bacteriologic results of 1,982 breast pump milk samples collected in three different settings showed a major decrease of the microbial contamination using either sterile device or decontamination with CS compared to a simple soap washing. The main messages from our study are to propose a guideline for the safe use of CS and to define situations when breast pump decontamination might be necessary: vulnerable babies for which sterile device is recommended; special circumstances, for example the current COVID-19 pandemic; special situations, for example women living in precarious conditions; or women pumping their milk at work but that would have low or no access to boiled water. Overall, cold decontamination reduced losses of milk for bacteriological reasons in human milk banks and may also be interesting to prevent horizontal contamination by virus like COVID-19.

The Acceptability, Feasibility, and Effectiveness of Breast Massage Combined with Acupoint Stimulation to Promote the Volume of Human Milk in Mothers with Preterm Infants: A Pilot Study

Background. Preterm infant mothers have always encountered difficulties in human milk production. For this reason, an intervention of breast massage combined with acupoint stimulation was designed to increase the production. Purpose. Through a pilot randomized trial, we assessed the acceptability, feasibility, and effectiveness of breast massage combined with acupoint stimulation and the study procedures. Methods. 40 participants of preterm infants born at less than 34 weeks of gestation were randomly allocated to the CG (control group) or the EG (group with breast massage combined with acupoint stimulation). Data related to the acceptability, feasibility, and effectiveness of the intervention and research procedures were collected and analysed. Results. The daily volume progressively increased each day in the first 7 days in both groups and a significant difference was observed between the groups ( $P$  < 0.001). The initiation time of lactogenesis stage II was 50.06 ± 6.78 (40.00–64.00) hours in the EG and 66.18 ± 14.64 (48.00–96.00) hours in the CG, where a significant difference was detected ( $P$  < 0.05). The mean score of satisfaction with the intervention in the EG was 4.56 ± 0.32 (4.0–5.0), while the retention rates were 82.5% and 85.5% (17/20) in the CG, and 80% (16/20) in the EG. Conclusion. This pilot study was oriented towards the effectiveness of breast massage combined with acupuncture stimulation for the increase of human milk production in the participants. The intervention was accepted well and the study process was reasonable. A large-scale RCT will be able to determine the beneficial effects of this intervention on human milk production.

Marketing Breastfeeding Substitutes: A Discussion Document

Marketing influences knowledge, attitudes, and decisions related to infant and young child nutrition, safety, development, parental confidence, and other aspects of health and wellbeing of the child. These attitudes and behaviours of parents, health workers, policy makers, and other influencers have short- and long-term effects on the child. There is an International Code of Marketing of Breast-Milk Substitutes. Is it time to have a code of marketing of breastfeeding substitutes?

Cost-effectiveness evidence for strategies to promote or support breastfeeding: a systematic search and narrative literature review

BACKGROUND

Global health policy recommends exclusive breastfeeding until infants are 6 months. Little is known about the cost-effectiveness of breastfeeding promotion strategies. This paper presents a systematic search and narrative review of economic evaluations of strategies to support or promote breastfeeding. The aim of the review is to bring together current knowledge to guide researchers and commissioners towards potentially cost-effective strategies to promote or support breastfeeding.

METHODS

Searches were conducted of electronic databases, including MEDLINE and Scopus, for economic evaluations relevant to breastfeeding, published up to August 2019. Records were screened against pre-specified inclusion/exclusion criteria and quality was assessed using a published checklist. Costs reported in included studies underwent currency conversion and inflation to a single year and currency so that they could be compared. The review protocol was registered on the PROSPERO register of literature reviews (ID, CRD42019141721).

RESULTS

There were 212 non-duplicate citations. Four were included in the review, which generally indicated that interventions were cost-effective. Two studies reported that breastfeeding promotion for low-birth weight babies in critical care is associated with lower costs and greater health benefits than usual care and so is likely to be cost-effective. Peer-support for breastfeeding was associated with longer duration of exclusivity with costs ranging from £19-£107 per additional month (two studies).

CONCLUSIONS

There is limited published evidence on the cost-effectiveness of strategies to promote breastfeeding, although the quality of the current evidence is reasonably high. Future studies should integrate evaluations of the effectiveness of strategies with economic analyses.

Origins of human milk microbiota: new evidence and arising questions

Human milk contains a diverse community of bacteria. The growing appreciation of commensal microbes and increasing availability of high-throughput technology has set the stage for a theory-driven approach to the study of milk microbiota, and translation of this knowledge to improve maternal and child health. We recently profiled the milk microbiota of healthy Canadian mothers and applied theory-driven causal modeling, finding that mode of breast milk feeding (nursing directly at the breast vs. pumping and feeding breast milk from a bottle) was significantly associated with milk microbiota composition. This observation could reflect an increased exposure to pumps and/or a decreased exposure to the infant mouth. Either way, it provides evidence for the retrograde mechanism of milk inoculation. Here, we discuss the implications of this research and related controversies, and raise new questions about the origins and function of milk bacteria.

Interventions to improve linear growth during exclusive breastfeeding life-stage for children aged 0-6 months living in low- and middle-income countries: a systematic review with network and pairwise meta-analyses

Background: Exclusive breastfeeding (EBF) during the first six months of life is critical for child's linear growth. While there is strong evidence in favor of EBF, the evidence with regards to other interventions for linear growth is unclear. We evaluated intervention domains of micronutrients, food supplements, deworming, maternal education, water sanitation and hygiene (WASH), and kangaroo care, for their comparative effectiveness on linear growth. Methods: For this review, we searched for randomized clinical trials (RCTs) of the interventions provided to infants aged 0-6 months and/or their breastfeeding mothers in low- and middle-income countries reporting on length-for-age z-score (LAZ), stunting, length, and head circumference. We searched for reports published until September 17 th, 2019 and hand-searched bibliographies of existing reviews. For LAZ and stunting, we used network meta-analysis (NMA) to compare the effects of all interventions except for kangaroo care, where we used pairwise meta-analysis to compare its effects versus standard-of-care. For length and head circumference, we qualitatively summarized our findings. Results: We found 29 RCTs (40 papers) involving 35,119 mother and infant pairs reporting on the effects of aforementioned interventions on linear growth outcomes. Our NMA on LAZ found that compared to standard-of-care, multiple micronutrients administered to infants (MMN-C) improved LAZ (mean difference: 0.20; 95% credible interval [CrI]: 0.03,0.35), whereas supplementing breastfeeding mothers with MMN did not (MMN-M, mean difference: -0.02, 95%CrI: -0.18,0.13). No interventions including MMN-C (relative risk: 0.74; 95%CrI: 0.36,1.44) reduced risk for stunting compared to standard-of-care. Kangaroo care, on the other hand, improved head circumference (mean difference: 0.20 cm/week; 95% confidence intervals [CI]: 0.09,0.31 cm/week) and length (mean difference: 0.23 cm/week; 95%CI: 0.10,0.35 cm/week) compared to standard-of-care.   Conclusion: Our study found important improvements for kangaroo care, but we did not find sufficient evidence for other interventions.

Grading the evidence to identify strategies to modify risk for necrotizing enterocolitis

Although risk for necrotizing enterocolitis (NEC) is often presented from the perspective of a premature infant's vulnerability to nonmodifiable risk factors, in this paper we describe the evidence and present recommendations to manage modifiable risks that are amenable to clinical actions. Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, we present recommendations in the context of their supporting evidence in a way that balances risks (e.g. potential harm, cost) and benefits. Across the prenatal, intrapartum, early and late clinical course, strategies to limit NEC risk in premature infants are presented. Our goal is to summarize modifiable NEC risk factors, grade the evidence to offer quality improvement (QI) targets for healthcare teams and offer a patient-family advocate's perspective on how to engage parents to recognize and reduce NEC risk.

Oral galactagogues (natural therapies or drugs) for increasing breast milk production in mothers of non-hospitalised term infants

BACKGROUND

Many women express concern about their ability to produce enough milk, and insufficient milk is frequently cited as the reason for supplementation and early termination of breastfeeding. When addressing this concern, it is important first to consider the influence of maternal and neonatal health, infant suck, proper latch, and feeding frequency on milk production, and that steps be taken to correct or compensate for any contributing issues. Oral galactagogues are substances that stimulate milk production. They may be pharmacological or non-pharmacological (natural). Natural galactagogues are usually botanical or other food agents. The choice between pharmacological or natural galactagogues is often influenced by familiarity and local customs. Evidence for the possible benefits and harms of galactagogues is important for making an informed decision on their use.

OBJECTIVES

To assess the effect of oral galactagogues for increasing milk production in non-hospitalised breastfeeding mother-term infant pairs.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Health Research and Development Network - Phillippines (HERDIN), Natural Products Alert (Napralert), the personal reference collection of author LM, and reference lists of retrieved studies (4 November 2019).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) comparing oral galactagogues with placebo, no treatment, or another oral galactagogue in mothers breastfeeding healthy term infants. We also included cluster-randomised trials but excluded cross-over trials.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two to four review authors independently selected the studies, assessed the risk of bias, extracted data for analysis and checked accuracy. Where necessary, we contacted the study authors for clarification.

MAIN RESULTS

Forty-one RCTs involving 3005 mothers and 3006 infants from at least 17 countries met the inclusion criteria. Studies were conducted either in hospitals immediately postpartum or in the community. There was considerable variation in mothers, particularly in parity and whether or not they had lactation insufficiency. Infants' ages at commencement of the studies ranged from newborn to 6 months. The overall certainty of evidence was low to very low because of high risk of biases (mainly due to lack of blinding), substantial clinical and statistical heterogeneity, and imprecision of measurements. Pharmacological galactagogues Nine studies compared a pharmacological galactagogue (domperidone, metoclopramide, sulpiride, thyrotropin-releasing hormone) with placebo or no treatment. The primary outcome of proportion of mothers who continued breastfeeding at 3, 4 and 6 months was not reported. Only one study (metoclopramide) reported on the outcome of infant weight, finding little or no difference (mean difference (MD) 23.0 grams, 95% confidence interval (CI) -47.71 to 93.71; 1 study, 20 participants; low-certainty evidence). Three studies (metoclopramide, domperidone, sulpiride) reported on milk volume, finding pharmacological galactagogues may increase milk volume (MD 63.82 mL, 95% CI 25.91 to 101.72; I² = 34%; 3 studies, 151 participants; low-certainty evidence). Subgroup analysis indicates there may be increased milk volume with each drug, but with varying CIs. There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints, such as tiredness, nausea, headache and dry mouth (very low-certainty evidence). No adverse effects were reported for infants. Natural galactagogues Twenty-seven studies compared natural oral galactagogues (banana flower, fennel, fenugreek, ginger, ixbut, levant cotton, moringa, palm dates, pork knuckle, shatavari, silymarin, torbangun leaves or other natural mixtures) with placebo or no treatment. One study (Mother's Milk Tea) reported breastfeeding rates at six months with a concluding statement of "no significant difference" (no data and no measure of significance provided, 60 participants, very low-certainty evidence). Three studies (fennel, fenugreek, moringa, mixed botanical tea) reported infant weight but could not be meta-analysed due to substantial clinical and statistical heterogeneity (I² = 60%, 275 participants, very low-certainty evidence). Subgroup analysis shows we are very uncertain whether fennel or fenugreek improves infant weight, whereas moringa and mixed botanical tea may increase infant weight compared to placebo. Thirteen studies (Bu Xue Sheng Ru, Chanbao, Cui Ru, banana flower, fenugreek, ginger, moringa, fenugreek, ginger and turmeric mix, ixbut, mixed botanical tea, Sheng Ru He Ji, silymarin, Xian Tong Ru, palm dates; 962 participants) reported on milk volume, but meta-analysis was not possible due to substantial heterogeneity (I² = 99%). The subgroup analysis for each intervention suggested either benefit or little or no difference (very low-certainty evidence). There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints such as mothers with urine that smelled like maple syrup and urticaria in infants (very low-certainty evidence). Galactagogue versus galactagogue Eight studies (Chanbao; Bue Xue Sheng Ru, domperidone, moringa, fenugreek, palm dates, torbangun, moloco, Mu Er Wu You, Kun Yuan Tong Ru) compared one oral galactagogue with another. We were unable to perform meta-analysis because there was only one small study for each match-up, so we do not know if one galactagogue is better than another for any outcome.

AUTHORS' CONCLUSIONS

Due to extremely limited, very low certainty evidence, we do not know whether galactagogues have any effect on proportion of mothers who continued breastfeeding at 3, 4 and 6 months. There is low-certainty evidence that pharmacological galactagogues may increase milk volume. There is some evidence from subgroup analyses that natural galactagogues may benefit infant weight and milk volume in mothers with healthy, term infants, but due to substantial heterogeneity of the studies, imprecision of measurements and incomplete reporting, we are very uncertain about the magnitude of the effect. We are also uncertain if one galactagogue performs better than another. With limited data on adverse effects, we are uncertain if there are any concerning adverse effects with any particular galactagogue; those reported were minor complaints. High-quality RCTs on the efficacy and safety of galactagogues are urgently needed. A set of core outcomes to standardise infant weight and milk volume measurement is also needed, as well as a strong basis for the dose and dosage form used.

"We Just Kind of Had to Figure It Out": A Qualitative Exploration of the Information Needs of Mothers Who Express Human Milk

BACKGROUND

Human milk expression, primarily by pump, is practiced by the majority of breastfeeding mothers in affluent countries. Existing literature is focused on determining prevalence and duration rates and the factors behind this trend. There is less research exploring mothers' perspectives and experiences related to expression.

RESEARCH AIM

To gather the experiential wisdom of mothers with a focus on their information needs and sources related to human milk expression.

METHODS

Audiotaped interviews were conducted with 35 mothers of infants, aged birth to 24 months, who had expressed milk at least once in western Canada. This study was guided by interpretive description, an applied qualitative research approach.

RESULTS

Registered nurses and international board-certified lactation consultants were the most common sources of information, with Internet, friends/family, and other mothers also important. Inconsistent expression advice was confusing for participants, and many reported health care providers did not address all their expression learning needs. Desired topic areas included practical advice on how to express, determining expression frequency/timing/duration, milk storage guidelines, the influence of expression on milk supply, product information, and general support/encouragement.

CONCLUSIONS

Assessment of expression learning needs should be part of routine lactation support at each encounter. Nonjudgmental, factual guidance will assist mothers in making evidence-informed decisions related to expression practices that are consistent with their unique breastfeeding goals. This should be supplemented by reputable online resources that provide timely and accurate information as well as efforts to connect mothers with peer support groups.

Mechanisms of support for exclusive breastmilk expressers in the community: a scoping review

Background

The World Health Organization recommends that infants be exclusively breastfed until the age of six months. Breastfeeding is generally understood to mean the provision of human breastmilk to the infant by direct feeding at the breast, and interventions aimed at supporting exclusive breastfeeding are therefore targeted at this activity. However, breastfeeding is actually an umbrella term covering the provision of breastmilk to an infant by any means. Our population of interest is mothers who exclusively feed their infants indirectly using expressed breastmilk. Some research suggests that any expressing, and exclusively expressing in particular, can be a risk factor for early cessation of exclusive breastmilk provision, so we were interested to identify whether any specific support existed for exclusively expressing mothers outside of the context of premature infants and the Neonatal Intensive Care Unit setting.

Methods

A scoping review following the Joanna Briggs Institute approach was used to explore the phenomenon of formal and informal supports in the community for exclusively expressing mothers. Searches were run across academic databases and of government websites and infant feeding support organisations. Finally, an informal internet search was run using a simple search string.

Results

On analysis of results, there were no studies or articles that met the search criteria. An informal internet search linked us directly with websites and blogs that could be considered a form of support intervention. These informal results suggest that support material or programs could possibly exist in other modalities but we cannot find them in the context of this type of scoping review.

Conclusions

The results of the search corroborated what we had suspected – that exclusively expressing mothers are not specifically supported by usual channels for new parents and that it is also difficult to find acknowledgement that exclusive expression exists.

The absence of results demonstrates the relevance of this study: exclusively expressing mothers are an under-served population. If we wish to strive towards achievement of World Health Organization breastfeeding goals, exclusively expressing mothers require targeted support to assist in their infant feeding experience, and there is little formal evidence of it currently being provided.

Interventions to improve linear growth during exclusive breastfeeding life-stage for children aged 0-6 months living in low- and middle-income countries: a systematic review and network and pairwise meta-analyses

Background: Exclusive breastfeeding (EBF) during the first six months of life is critical for child's linear growth. While there is strong evidence in favor of EBF, the evidence with regards to other interventions for linear growth is unclear. We evaluated intervention domains of micronutrients, food supplements, deworming, maternal education, water sanitation and hygiene (WASH), and kangaroo care, for their comparative effectiveness on linear growth. Methods: For this review, we searched for randomized clinical trials (RCTs) of the interventions provided to infants aged 0-6 months and/or their breastfeeding mothers in low- and middle-income countries reporting on length-for-age z-score (LAZ), stunting, length, and head circumference. We searched for reports published until September 17 th, 2019 and hand-searched bibliographies of existing reviews. For LAZ and stunting, we used network meta-analysis (NMA) to compare the effects of all interventions except for kangaroo care, where we used pairwise meta-analysis to compare its effects versus standard-of-care. For length and head circumference, we qualitatively summarized our findings. Results: We found 29 RCTs (40 papers) involving 35,119 mother and infant pairs reporting on the effects of aforementioned interventions on linear growth outcomes. Our NMA on LAZ found that compared to standard-of-care, multiple micronutrients administered to infants (MMN-C) improved LAZ (mean difference: 0.20; 95% credible interval [CrI]: 0.03,0.35), whereas supplementing breastfeeding mothers with MMN did not (MMN-M, mean difference: -0.02, 95%CrI: -0.18,0.13). No interventions including MMN-C (relative risk: 0.74; 95%CrI: 0.36,1.44) reduced risk for stunting compared to standard-of-care. Kangaroo care, on the other hand, improved head circumference (mean difference: 0.20 cm/week; 95% confidence intervals [CI]: 0.09,0.31 cm/week) and length (mean difference: 0.23 cm/week; 95%CI: 0.10,0.35 cm/week) compared to standard-of-care.   Conclusion: Our study found important improvements for kangaroo care, but we did not find sufficient evidence for other interventions.

A randomized crossover trial comparing the Nifty cup to a medicine cup in preterm infants who have difficulty breastfeeding at Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana

INTRODUCTION

Preterm infants make up the majority of the 9 million babies born in Africa and South Asia requiring supplemental feedings as they transition to exclusive breastfeeding. The World Health Organization recommends the use of a cup to feed newborns with breastfeeding difficulties in low-resource settings. We set out to evaluate the Nifty cup, a new feeding cup designed specifically for infants with breastfeeding difficulties.

MATERIALS AND METHODS

We conducted a randomized clinical trial in Ghana. We hypothesized infants would prefer the Nifty cup and that it would have less spillage as compared to a medicine cup. We enrolled mothers and preterm infants with breastfeeding difficulties indicated to cup feed at Komfo Anokye Teaching Hospital. Each mother-infant pair used the Nifty cup and a standard medicine cup; and two feeding assessments with each cup were conducted. We employed an intent-to-treat analysis comparing cup preference using a Wilcoxon signed rank test and spillage using generalized estimating equations.

RESULTS

We enrolled 200 mothers and 237 infants. Many infants were very low birth weight (62%), less than two weeks old (62%), and multiple birth (29%). In response to separate questions about each cup, more mothers reported liking the Nifty cup a lot as compared to the medicine cup (85% versus 57%, p<0.001). When asked to choose between the two cups, more than 75% preferred the Nifty cup (p < 0.001). There was slightly less spillage with the Nifty cup (8.9%) versus the medicine cup (9.3%), which was not statistically significant (p = 0.35). Mothers reported greater confidence and ease of using the Nifty cup and greater use one-month post-discharge compared to the medicine cup (p-values <0.001). Nearly all mothers were breastfeeding and cup feeding their infants at study initiation and at one-month post-discharge.

DISCUSSION

This is the first randomized clinical trial of cup feeding in sub-Saharan Africa. Mothers prefer the Nifty cup to a medicine cup for supplemental feeds to their preterm infant. The Nifty cup was used with greater ease and confidence. The Nifty cup can offer an improved feeding experience for the mother-infant pair.

Turkish Neonatal Society guideline on nutrition of the healthy term newborn

Research shows strong evidence that breastfeeding offers many health benefits for infants and mothers, as well as potential economic and environmental benefits for communities. The World Health Organization recommends breastfeeding exclusively for up to 6 months of age, with continued breastfeeding along with appropriate complementary foods up to two years of age or beyond.

Women's views about a free breast pump service: Online survey informing intervention development

Improving breastfeeding outcomes is a global priority; however, in the United Kingdom, continuation of breastfeeding remains low. Growing empirical evidence suggests a free breast pump service might be an acceptable and feasible incentive intervention to improve breastfeeding outcomes and reduce heath inequalities. To inform intervention development, we conducted an online survey with women recruited via social media using snowball sampling. Data were analysed descriptively (closed questions) with qualitative thematic analysis (free text). The survey was completed by 666 women, most of whom had recently breastfed and used a breast pump. Participants agreed that free pump hire (rental/loan; 567 women; 85.1%) or a free pump to keep (408; 61.3%) should be provided. Free text comments provided by 408 women (free pump) and 309 women (free hire) highlighted potential benefits: helping women to continue breastfeeding; express milk; overcome difficulties; and pump choice. Concerns are possible effect on breast milk supply, reduced breastfeeding, pumps replacing good support for breastfeeding, and pump hire hygiene. Personal and societal costs are important issues. Some suggested a pump service should be for low-income mothers, those with feeding difficulties or sick/preterm infants. A one-size service would not suit all and vouchers were proposed. Some suggested fees and deposits to prevent waste. To our knowledge, this is the first study reporting views about the acceptability of providing a free breast pump hire service. Mothers support and wish to have a say in breast pump service development. Future evaluations should address impact on feeding outcomes, professional support, hygiene for hired pumps, and costs.

Fifteen-minute consultation: Breastfeeding in the first 2 weeks of life-a hospital perspective

The beneficial health and economic impacts of breastfeeding are considerable. However the majority of babies in the UK are not exclusively breastfeeding by 6 weeks of age. The first few weeks of life are therefore a critical period to facilitate breastfeeding. Health professionals must have a thorough knowledge of normal breastfeeding patterns in order to minimise unnecessary interference, and an understanding of how to protect the breastfeeding relationship when medical problems occur.

High-Temperature Short-Time Pasteurization System for Donor Milk in a Human Milk Bank Setting

Donor milk is the best alternative for the feeding of preterm newborns when mother's own milk is unavailable. For safety reasons, it is usually pasteurized by the Holder method (62.5°C for 30 min). Holder pasteurization results in a microbiological safe product but impairs the activity of many biologically active compounds such as immunoglobulins, enzymes, cytokines, growth factors, hormones or oxidative stress markers. High-temperature short-time (HTST) pasteurization has been proposed as an alternative for a better preservation of some of the biological components of human milk although, at present, there is no equipment available to perform this treatment under the current conditions of a human milk bank. In this work, the specific needs of a human milk bank setting were considered to design an HTST equipment for the continuous and adaptable (time-temperature combination) processing of donor milk. Microbiological quality, activity of indicator enzymes and indices for thermal damage of milk were evaluated before and after HTST treatment of 14 batches of donor milk using different temperature and time combinations and compared to the results obtained after Holder pasteurization. The HTST system has accurate and simple operation, allows the pasteurization of variable amounts of donor milk and reduces processing time and labor force. HTST processing at 72°C for, at least, 10 s efficiently destroyed all vegetative forms of microorganisms present initially in raw donor milk although sporulated Bacillus sp. survived this treatment. Alkaline phosphatase was completely destroyed after HTST processing at 72 and 75°C, but γ-glutamil transpeptidase showed higher thermoresistance. Furosine concentrations in HTST-treated donor milk were lower than after Holder pasteurization and lactulose content for HTST-treated donor milk was below the detection limit of analytical method (10 mg/L). In conclusion, processing of donor milk at 72°C for at least 10 s in this HTST system allows to achieve the microbiological safety objectives established in the milk bank while having a lower impact regarding the heat damage of the milk.

Optimizing Nutrition in Preterm Low Birth Weight Infants-Consensus Summary

Preterm birth survivors are at a higher risk of growth and developmental disabilities compared to their term counterparts. Development of strategies to lower the complications of preterm birth forms the rising need of the hour. Appropriate nutrition is essential for the growth and development of preterm infants. Early administration of optimal nutrition to preterm birth survivors lowers the risk of adverse health outcomes and improves cognition in adulthood. A group of neonatologists, pediatricians, and nutrition experts convened to discuss and frame evidence-based recommendations for optimizing nutrition in preterm low birth weight (LBW) infants. The following were the primary recommendations of the panel: (1) enteral feeding is safe and may be preferred to parenteral nutrition due to the complications associated with the latter; however, parenteral nutrition may be a useful adjunct to enteral feeding in some critical cases; (2) early, fast, or continuous enteral feeding yields better outcomes compared to late, slow, or intermittent feeding, respectively; (3) routine use of nasogastric tubes is not advisable; (4) preterm infants can be fed while on ventilator or continuous positive airway pressure; (5) routine evaluation of gastric residuals and abdominal girth should be avoided; (6) expressed breast milk (EBM) is the first choice for feeding preterm infants due to its beneficial effects on cardiovascular, neurological, bone health, and growth outcomes; the second choice is donor pasteurized human milk; (7) EBM or donor milk may be fortified with human milk fortifiers, without increasing the osmolality of the milk, to meet the high protein requirements of preterm infants; (8) standard fortification is effective and safe but does not fulfill the high protein needs; (9) use of targeted and adjustable fortification, where possible, helps provide optimal nutrition; (10) optimizing weight gain in preterm infants prevents long-term cardiovascular complications; (11) checking for optimal weight and sucking/swallowing ability is essential prior to discharge of preterm infants; and (12) appropriate counseling and regular follow-up and monitoring after discharge will help achieve better long-term health outcomes. This consensus summary serves as a useful guide to clinicians in addressing the challenges and providing optimal nutrition to preterm LBW infants.

Reliance on Pumped Mother's Milk Has an Environmental Impact

Breastfeeding is an environmentally friendly process; however when feeding relies on pumped mother’s milk, the environmental picture changes. Waste plastics and heavy metals raise concerns regarding resource efficiency, waste treatment, and detrimental effects on health. Reliance on pumped milk rather than breastfeeding may also effect obesity and family size, which in turn have further environmental impacts. Information on pump equipment rarely includes environmental information and may focus on marketing the product for maximum profit. In order for parents, health workers, and health policy makers to make informed decisions about the reliance on pumped mother’s milk, they need information on the broad and far reaching environmental aspects. There was no published research found that examined the environmental impact of using pumped mother’s milk. A project is ongoing to examine this issue.
