Abstract
Introduction This study aimed to assess if the implementation of a gentle transition of vacuum mode into a breast pump suction pattern commonly used to initiate milk production would improve user comfort while expressing during the first four days postpartum. Methods This prospective study was conducted at OLVG hospital in the Netherlands in two sequential phases. Breastfeeding patients delivering >36 weeks gestation with an infant aged ≤96 h old and a clinical indication to express milk with a breast pump were recruited. Intervention group 1 (n = 40) used a hospital-grade electric breast pump with a standard breast pump suction pattern. Intervention group 2 used a hospital-grade electric breast pump with a modified breast pump suction pattern (n = 40). The primary outcome was an objective assessment of comfort as measured by participants' need to reduce vacuum level during the 20 min test session. Secondary outcomes included the total expression volume (ml) in 20 min pumping. Results The study found that the primary outcome of comfort was significantly improved with the modified breast pump suction pattern compared to the standard pattern (OR 1.29, 95% CI 1.08 to 1.6) with 86% vs. 67% of participants not needing to reduce applied vacuum levels. The amount of milk expressed did not differ significantly between phases (group 1: 7.6 ml (2.7-25.5 ml), group 2: 12.0 ml (1.2-31.5 ml), p = 0.43). Discussion This study is the first to demonstrate an improvement in user comfort driven by the implementation of gentle transitions in vacuum modes in a commonly used breast pump suction pattern. Research into this novel population combining both pumping and breastfeeding in the first days after birth offers new unique insights on the requirements of breast pump suction patterns. Trial registration Registered on clinical trials.gov NCT04619212. Date of registration November 6, 2020.

Abstract
Aware of the utmost importance of feeding premature babies-especially those of lower weight-with human milk, as well as the need to monitor this important element of neonatal care, we focused on four aspects in this review. First of all, we reviewed the beneficial effects of feeding premature infants with breast milk in the short and long term. Secondly, we performed a quantitative evaluation of the rates of breastfeeding and feeding with human milk in Very-Low-Birth-Weight infants (VLBWs) during hospitalization in the Neonatal Intensive Care Unit (NICU) and at discharge. Our aim was to take a snapshot of the current status of human milk-feeding care and track its trends over time. Then we analyzed, on the one hand, factors that have been proven to facilitate the use of maternal milk and, on the other hand, the risk factors of not feeding with breast milk. We also considered the spread of human milk banking so as to assess the availability of donated milk for the most vulnerable category of premature babies. Finally, we proposed a protocol designed as a tool for the systematic monitoring of actions that could be planned and implemented in NICUs in order to achieve the goal of feeding even more VLBWs with human milk.

The relationship between creamatocrit and cumulative percentage of total milk volume: a cross-sectional study in mothers of very preterm infants in Bangkok, Thailand. Int Breastfeed J 2023; 18:63.

Abstract
BACKGROUND Human hindmilk contains higher concentrations of fat than foremilk and is more desirable for growth in preterm infants who can tolerate limited volumes of breastmilk. There is currently no clear demarcation between foremilk and hindmilk. This study characterized the change in breastmilk's fat content from the start to end of milk flow and defined this demarcation. METHODS Mothers of infants born at ≤ 32 weeks gestational age and ≥ 14 days after childbirth in a University hospital in Bangkok, Thailand between July, 2011, and April, 2012 were included in this cross-sectional study. Breastmilk samples were sequentially collected from the start to end of milk flow in 5-mL aliquots using breast pumps. The fat content of each aliquot from each breast was determined through creamatocrit. The average creamatocrit of foremilk and hindmilk were compared in predefined foremilk to hindmilk ratios of 20:80, 25:75, 33:67, and 50:50. Creamatocrit of the first and last aliquots were compared for mothers who expressed low- (≤ 25-mL per breast) and high-volumes (> 25-mL per breast) of breastmilk. RESULTS Of the 25 mothers enrolled, one was excluded due to unsuccessful creamatocrit measurement. The last aliquot of breastmilk had a significantly higher creamatocrit than the first from the same breast (median [interquartile range] of 12.7% [8.9%, 15.3%] vs. 5.6% [4.3%, 7.7%]; test statistic 1128, p < 0.001). Mean creamatocrit in hindmilk portions (9.23%, 9.35%, 9.81%, and 10.62%, respectively) was significantly higher than foremilk portions (6.28%, 6.33%, 6.72%, and 7.17%, respectively) at all predefined ratios. Creamatocrit increased by 1% for every 10% incremental increase in expressed breastmilk volume until the breast was emptied. Low-volume mothers had a significantly higher creamatocrit in the first aliquot compared with high-volume mothers (U = 437, p = 0.002). No significant difference in breastmilk volume was observed between mothers with and without breastfeeding experience. CONCLUSIONS Fat content in breastmilk increased on an incremental basis. More fluid definitions of foremilk and hindmilk should be adopted. Mothers should prepare their breastmilk into aliquots based on the required feeding volume of their infant. Hindmilk aliquots can be prioritized over foremilk aliquots to ensure infants obtain optimal caloric intake.

Abstract
BACKGROUND Sleep is essential for optimal health, and disturbed postpartum sleep is associated with compromised infant attachment. The postpartum experience of mothers with preterm infants is unlike the biological norm, as they are separated from their infants and often express breast milk. PURPOSE The purpose of this study was to examine the feasibility of conducting a clinical research study among women with hospitalized preterm infants. We also explored for associations between maternal sleep patterns and sleep-related psychological states and subsequent breast milk volume. METHODS Participants were recruited from Magee-Womens Hospital, located in Pittsburgh, Pennsylvania New mothers completed daily sleep and pumping logs and scales to measure stress, trauma, depression, fatigue, and sleep quality. RESULTS A total of 78 women were screened, 18 women consented, and a total of 8 participants completed the study. Screening from the postpartum unit increased recruitment. The participants experience worsening sleep quality over time, moderate stress, and fatigue. Stress, postnatal depression, and fatigue are negatively associated with milk volume. IMPLICATIONS FOR PRACTICE AND RESEARCH Postpartum recruitment with frequent follow-ups improved recruitment and retention. We present a preliminary association between maternal stress, fatigue, and depression, and subsequent breast milk volume. Sleep-related psychological states may negatively influence milk volume.

Abstract
Background Exclusive breastfeeding (EBF) in the first 6 weeks postpartum is key to continued breastfeeding. This study aimed to explore the role of EBF-related predictors (particularly breastfeeding intention) in breastfeeding behavior among preterm mothers at week 6 postpartum based on the theory of planned behavior (TPB). Methods A total of 352 mothers of preterm infants were recruited, 340 of whom participated in this study. Prior to discharge, participants completed the Chinese versions of the modified Breastfeeding Attrition Predictive Tool, the Breastfeeding Knowledge Questionnaire (BKQ), the Infant Feeding Intention, and the Edinburgh Postnatal Depression Scale. Responses to the items of the Breastfeeding Behavioral Questionnaire (BBQ) were also collected by telephone at week 6 postpartum. The final analyses included 321 participants who completed the full two-wave data collection. Results The fitness indices of the modified TPB model were acceptable. Breastfeeding knowledge and EBF before discharge positively impacted breastfeeding intention, whereas depression had a negative impact. Before discharge, breastfeeding intention fully mediated the impacts of breastfeeding attitude, social and professional support, knowledge, depression, and EBF on breastfeeding behavior and partially mediated the influence of perceived breastfeeding control on breastfeeding behavior. Conclusion These findings indicate that TPB accurately predicts breastfeeding behavior among preterm mothers at week 6 postpartum, and breastfeeding intention is key to the above-mentioned EBF-related factors and breastfeeding behavior. The findings underline the need for further longitudinal studies and corresponding interventions for preterm mothers with a high risk of EBF attrition.

Abstract
Nutrition management of the high-risk infant after hospital discharge is complicated by the infant's dysfunctional or immature oral feeding skills, nutritional deficits, and the family's feeding plan. Although evidence is limited, available studies point to developing an individualized nutritional plan, which accounts for these factors; protects and prioritizes the family's plan for breastfeeding; and promotes an acceptable growth pattern. Further research is needed to identify the type and duration of posthospital discharge nutrition to optimize high-risk infant neurodevelopment and body composition. Attention to infant growth, lactation support, and safe feed preparation practices are critical in the transition to home.

Abstract
Introduction: Mothers of preterm infants are at risk for inadequate milk production. Pumping logs are often used to both encourage lactation in the first week and track its efficacy. Our objectives were to determine whether mothers of preterm infants who keep pumping logs are demographically different from those who do not and to determine whether this practice affects the amount of mother's own milk (MOM) fed to their infants. We also aimed at determining whether there is a correlation between: (1) time to first breast milk expression, (2) cumulative frequency of expression in the first week, and (3) milk volume on day 7 with subsequent milk volumes and percent of infant diet consisting of MOM. Methods: Mothers of infants born ≤32 weeks and ≤1,500 g were enrolled within 48 hours of birth and encouraged to keep a pumping log. Data were collected on maternal characteristics, patterns of milk expression, and milk volumes on days 7, 14, 21, and 28 after delivery. Infant data were collected via chart review. Results: Mothers who kept pumping logs provided their own milk for a greater percentage of their infant's feeds at the time of achieving full feeds (p = 0.017). The total number of expressions in the first week was correlated with milk volume on day 21 (p = 0.016) and the provision of a higher percentage of MOM feeds at discharge (p = 0.03). Milk volume on day 7 correlated with volumes obtained at days 14, 21, and 28 (p < 0.001). Conclusions: Pumping logs may affect the availability of MOM for preterm infants. Frequency of pumping in the first week and milk volume on day 7 may impact long-term lactation success for these women.

Abstract
BACKGROUND Improved health outcomes for critically ill infants including neurodevelopmental, immunological, and cost benefits are dependent upon the dose and duration of mother's own milk feedings. However, mothers of infants admitted to the neonatal intensive care unit (NICU) must express their milk (pump-dependent) and often struggle with milk production. PURPOSE To examine the state of the science on nonpharmacologic modifiable expression factors that may influence milk production in pump-dependent mothers of critically ill infants admitted to the NICU. DATA SOURCES PubMed, Embase, and CINAHL databases from 2005 to 2020. SEARCH STRATEGY Guided by the lactation conceptual model, the authors searched for peer-reviewed studies with terms related to milk volume, pump dependency, critically ill infants, and modifiable factors, which may influence milk volume and assessed 46 eligible studies. DATA EXTRACTION Data were extracted by 3 reviewers with a systematic staged review approach. RESULTS Evidence from 26 articles found expressed milk volume may be influenced by multiple potentially modifiable factors. Simultaneous expression with a hospital-grade electric pump at least 5 times per day beginning 3 to 6 hours after delivery, and adding complementary techniques including hand expression, hands-on-pumping, music, breast massage, warm compresses, skin-to-skin care, and the mother expressing near her infant may promote increased milk volume. IMPLICATIONS FOR PRACTICE AND RESEARCH Healthcare providers should assist pump-dependent mothers with early initiation and frequent milk removal with a hospital-grade breast pump. Further research is needed to explore optimal frequency of expressions, dose and timing of skin-to-skin care, and other targeted strategies to improve expressed milk volume.

Abstract
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.

Abstract
OBJECTIVE Preterm birth impacts approximately 10% of women globally. Midwives are often the first point of care after the birth of a preterm infant providing mothers with information and support for breast expression. However, despite guidelines that suggest expression within the first hour of birth, most first expressions occur much later. This study aimed to seek an understanding of midwives' experiences with the first expression for mothers of preterm infants, including the barriers and facilitators that midwives may face. DESIGN A qualitative design using semi-structured interviews via focus groups. Thematic analysis was used to identify relevant themes and sub-themes. PARTICIPANTS Participants included midwives providing care to women in preterm labour and birth at a tertiary maternity hospital in Australia (N=12). All participating midwives cared for mothers of preterm infants between 28 and 35 weeks' gestation up to six hours following birth. FINDINGS Two major themes resulted from the data, including the changing expectations of infant feeding and the responsibility versus expectation to support a woman to express in the first hour of birth with other competing clinical and organisational tasks. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Whilst individual philosophies on the benefits of human milk were positive, expressing in the birth suite was dictated by essential clinical tasks and by the institutions value placed on expressing in the first hour. Clear objectives to undertake expressing within the first hour or within the birth suite stay, need to be included in policy and supported by management and team leaders, to increase early expressing rates.

Abstract
Survival rates for extremely low-birth-weight (ELBW) infants are improving as neurodevelopmental impairment (NDI) rates stay stable, thereby increasing the overall number of infants with NDI. Although there are many determinants of NDI in this population, nutritional factors are of interest because they are readily modifiable in the clinical setting. Nurses can influence nutritional factors such as improving access to human milk feeding, using growth monitoring, establishing feeding policies, implementing oral care with colostrum, facilitating kangaroo care, and providing lactation education for the mother. All of these measures assist in leading to a decrease in NDI rates among ELBW infants.

Abstract
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. Trial registration ISRCTN16356650. Date assigned: 19/04/2021.

Abstract
Despite abundant research comparing postdischarge hospital diets for preterm infants, the ideal clinical approach has not been determined. Dilemmas persist because randomized controlled trials of preterm versus term infant formula have yielded equivocal results and because the predominant postdischarge diet for preterm infants has shifted from formula-based to a combination that includes maternal milk and increasingly includes a plan for breastfeeding. As the investigation of the influence of the post-hospital discharge diet on preterm infant outcomes evolves, factors to consider include the infant's oral feeding ability and the maternal lactation goal. The maturation of the preterm infant's oral feeding skills may at least partially explain why increased nutrient density appears to most benefit growth outcomes when given during the first 3 to 4 months after hospital discharge. At some point in maturation, the preterm infant may develop the ability to vary intake as needed to obtain sufficient nutrition no matter the density of the diet. In addition, attention to the maternal lactation goal is critical as intake of maternal milk likely influences neurodevelopmental outcomes as much or even to a greater extent than growth trajectory.

Abstract
Objective: Milk expression is the key step of milk production in mothers of preterm infants. Our hospital has started an electrical breast pump loaning program to improve human milk feeding rate in our patients. This study was aimed to assess the beneficial effect of the loaning program. Materials and Methods: This was an interrupted time-series study. In addition to general information, mothers in the intervention period received electrical breast pump before discharge. Maternal milk volume was recorded for 28 days, and 24-hour-feeding record and recall were used to determine breastfeeding rate at discharge and 6 months postpartum, respectively. Results: There were 40 mothers, 20 mothers in each group, who participated in this study. Maternal milk volume in the control group was 169.3 + 152.4, 329.5 + 241.6, 547.4 + 390.8, and 704.2 + 439.6 mL/day in first, second, third, and fourth week, respectively. Milk volume in the intervention group was 308.5 + 269.6, 454.1 + 281, 544.9 + 282.2, and 531.9 + 282.2 mL/day in first, second, third, and fourth week. Average frequency of milk expression was higher in the intervention group [5.15 (1) and 6.01 (1.49) times per day, p-value 0.04]. There were one (5%) and four (20%) infants in the control and intervention groups who were exclusively breastfed at discharge. At 6 months, eight (40%) infants from each group were still breastfed. Conclusion: Mothers in the pump loaning program had expressed milk more frequently. Even though maternal milk volume difference did not reach statistical significance, the intervention group had higher milk volume in the first 2 weeks postpartum. There was no difference in terms of feeding type both at discharge and 6 months postpartum.

Abstract
Objective: This study examined the effect of postpartum administration of depo medroxyprogesterone acetate (DMPA) on milk production, time to onset of secretory activation, lactation duration, and infant consumption of mother's own milk (MOM) in mothers of preterm very low-birth-weight (VLBW) infants. Materials and Methods: We conducted a secondary analysis of data from mothers who delivered infants weighing ≤1,500 g and at ≤32 weeks' gestation. The volume of milk produced was measured on days 1-7, 14, and 21 by weighing all expressed milk on an electronic scale. Time to secretory activation was determined through self-report of a feeling of breast fullness. Information on lactation duration and the percent of feeds consisting of MOM consumed by infants was obtained from the medical records. Results: Mothers who received postpartum DMPA were more likely to be African American (72.4% versus 31.4%; p = 0.0006), unemployed (65.5% versus 44.5%; p = 0.027), and Medicaid eligible (89.7% versus 67.2%; p = 0.019). There were no differences in daily milk production between mothers who received DMPA before hospital discharge (n = 29) compared with those who did not (n = 141). When mothers who reached secretory activation before receiving DMPA were removed from analysis, receiving DMPA was associated with a later onset of secretory activation (103.7 versus 88.6 hours; p = 0.028). There were no statistically significant differences between the study groups in lactation duration or infant MOM consumption. Conclusions: DMPA, when administered postpartum to mothers of preterm VLBW infants, delayed secretory activation, but had no detrimental effect on milk production or lactation duration.

Abstract
BACKGROUND Breast care is an important routine during pregnancy and breastfeeding. Its absence leads to inadequate milk production before and after childbirth. OBJECTIVE This study aimed to determine the status of breast care during pregnancy, which is related to milk production and disease after childbirth in the Tinggede Health Center, Sigi Regency, Central Sulawesi. METHODS The method used was an analytic survey with a cross-sectional approach and the samples were 82 breastfeeding mothers in the working area of the Tinggede Health Center. The sampling used a total population, and data were obtained by interview and observation. Furthermore, the analysis technique used Chi-Square. RESULTS The results showed there was a relationship between breast care during pregnancy with milk production (p = 0.001), and breast care status with a disease (p = 0.012). The common diseases suffered by breastfeeding mothers due to inadequate care are non-protruding nipples, infections, blocked milk ducts, mastitis, and lumps. CONCLUSIONS Breastfeeding mothers' failure to care for their breasts during pregnancy can lead to lack of milk production and diseases such as non-protruding nipples, infections, blocked milk ducts, mastitis, and lumps.

Abstract
BACKGROUND Mother's own milk (MOM) is well known to decrease prematurity-related morbidities, yet mothers delivering preterm infants often produce insufficient quantities of milk to provide these benefits. Although a critical need exists for research to support lactation success in this vulnerable population, development and investigation of interventions to increase available MOM for infant consumption requires consistent, valid, and reliable measures of lactation outcomes. OBJECTIVES The aim of this study was to compare and contrast methods of measuring lactation outcomes in mothers of preterm infants and evaluate their advantages and disadvantages. METHODS Measures of lactation outcomes were reviewed and synthesized. Insights on best practices and future research directions are provided. RESULTS Volume of MOM produced, lactation duration, and time to onset of secretory activation are important measures of lactation success. The most valid and reliable measure of milk production is likely weighing each vial of expressed milk combined with test weighing when infants breastfeed. Measures of lactation duration should include actual days mothers lactated rather than limiting to infant consumption of MOM as a proxy for duration and include not only whether mothers are lactating at infant discharge but whether they are also lactating at other health-relevant time points during hospitalization. Although time to onset of secretory activation is an important lactation outcome, information regarding valid and reliable indicators of onset in women delivering preterm infants is limited, and investigation of such indicators is a research priority. Variables that may affect lactation outcomes, including time to initiation of expression following delivery, duration of expression sessions, expression method, time spent in skin-to-skin care, maternal demographics and comorbidities, as well as maternal intent to lactate, must be considered when researchers investigate lactation outcomes in mothers of very low birth weight infants. DISCUSSION Consistent and valid measures of lactation outcomes are required to produce reliable results from which evidence-based practice recommendations can be developed in order to improve lactation success in this vulnerable population.

Abstract
The amount of milk production in mothers of babies admitted to the neonatal intensive care unit (NICU) is mostly determined by some actions focused on the first hours and days after birth. Working for an improvement in our previous results in terms of maternal expressed breast milk (MEBM) production, we designed a pilot project and a small observational study. After increasing the number of breast milk pumps to allow full-time availability and implementing educational strategies and updated information for parents, the volume of MEBM production by day 14 after birth was doubled and increased to >500 mL per day. The rate of exclusive breastfeeding at discharge improved from 26.67% to 76.19%. The cost of the use of donor milk per patient decreased by 15.7%. This study is an example of a cost-beneficial quality improvement strategy. It demonstrates the importance of an optimal supply of breast milk pumps in NICU and educational interventions focused on enhancing MEBM production.

Abstract
Mother's own milk (MOM) feeding is a cost-effective strategy to reduce risks of comorbidities associated with prematurity and improve long-term health of infants hospitalized in the Neonatal Intensive Care Unit (NICU). Significant racial and socioeconomic disparities exist in MOM provision in the NICU, highlighting the importance of developing strategies to reduce these disparities. Mothers of infants in the NICU experience many health concerns which may negatively impact lactation physiology. Objective measures of lactation physiology are limited but may assist in identifying mothers at particular risk. Several strategies to assist mothers of hospitalized infants are essential, including maternal education, qualified lactation professionals, early and frequent milk expression with a hospital-grade double electric breast pump, and providing support for transitioning to direct breastfeeding prior to discharge from the NICU.

Abstract
Objective: Mothers of many preterm babies are unable to produce sufficient milk for their babies during the prolonged hospitalization. Domperidone stimulates the release of prolactin, thereby increasing breast milk production. The primary outcome was to study the efficacy of domperidone in augmenting breast milk production in mothers with lactation failure (LF). The secondary outcomes included the effect of domperidone on prolactin levels, adverse effects of domperidone, and outcome on breastfeeding rates at discharge. Materials and Methods: This was a randomized, double-blinded, placebo-controlled trial where mothers with LF were either allocated domperidone (10 mg) or placebo, 2 tablets three times a day for 14 days. Milk volumes were recorded daily for 14 days. Serum prolactin levels were measured at the start and at day 7 of study. Results: Out of 166 women eligible for the study, 119 (71.7%) mothers were able to increase their breast milk production without pharmacological treatment after being counseled on the advantages of human milk and proper breastfeeding management. Forty-seven mothers were finally enrolled in the study; 24 in the domperidone group (DG) and 23 in the placebo group (PG). Breast milk production increased from a baseline of 156 + 141.1 to 400.9 + 239.2 mL in the DG and increased from a baseline of 175.8 + 150.7 to 260.5 + 237.5 mL in the PG, after 14 days (p < 0.01). The prolactin levels in the DG and PG increased from 72.85 (22.2-167.15) and 42.33 (14.02-93.54) ng/mL, respectively, to 223.4 (49.79-280.2) ng/mL (p = 0.005) in the DG and 60.08 (14.31-132.14) ng/mL (p = 0.232) in the PG on the 7th day of treatment. No adverse effects were recorded. Ninety-five percent of babies in the DG were exclusively breastfeeding at hospital discharge, compared with 52.4% in the PG (p = 0.008). Conclusion: Domperidone treatment can result in an increase in breast milk production with no adverse effects. The study was registered with the Thai Clinical Trials Registry ID TCTR2020091008.

Abstract
UNLABELLED As part of the Pre-B Project, a systematic review was conducted to evaluate associations between exclusive maternal milk (≥75%) intake and exclusive formula intake and growth and health outcomes in very-low-birthweight (VLBW) preterm infants. The protocols from the Academy of Nutrition and Dietetics' Evidence Analysis Center and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist were followed. Thirteen observational studies were included; 11 studies reported data that could be synthesized in a pooled analysis. The evidence is very uncertain (very low quality) about the effect of exclusive maternal milk on all outcomes due to observational study designs and risk of selection, performance, detection, and reporting bias in most of the included studies. Very-low-quality evidence suggested that providing VLBW preterm infants with exclusive maternal milk was not associated with mortality, risk of necrotizing enterocolitis, sepsis, or developing bronchopulmonary dysplasia, as compared with exclusive preterm formula, but exclusive maternal milk was associated with a lower risk of retinopathy of prematurity (very low certainty). Results may change when additional studies are conducted. There was no difference in weight, length, and head circumference gain between infants fed fortified exclusive maternal milk and infants receiving exclusive preterm formula; however, weight and length gain were lower in infants fed non-fortified exclusive maternal milk. Given the observational nature of human milk research, cause-and-effect evidence was lacking for VLBW preterm infants.

Abstract
INTRODUCTION Due to immature brain development, preterm infants are more likely to develop neurological developmental defects compared with full-term infants. Most preterm infants without neurodevelopmental damage can eventually reach the same scholastic level as their same-age peers; however, some show persistent impairment. Breast feeding (BF), which is an important public health measure, is of great significance for preterm infants. Various active substances in breast milk promote the development of the brain and central nervous system in premature infants. We present a protocol for a prospective longitudinal cohort study to explore the effect of in-hospital BF on brain development in preterm infants and possible influencing factors. METHODS AND ANALYSIS This study will enrol 247 Chinese preterm infants (gestational age: 30-34 weeks) delivered in Women's Hospital School of Medicine, Zhejiang University, and transferred to the neonatal intensive care unit. Demographic, clinical and in-hospital BF data will be collected through electronic medical records. Moreover, follow-up data will be obtained by telephone, interview or online. Measurements will be obtained using the Breastfeeding Self-Efficacy Scale-Short Form, neuroimaging with functional near-infrared spectroscopy, extrauterine growth restriction and the Ages and Stages Questionnaire. Follow-up will be performed at 3, 6 and 12 months after birth. ETHICS AND DISSEMINATION This study has been approved by the Women's Hospital School of Medicine Zhejiang University Medical Ethics Committee (2019-058). The study results are expected to be published in peer-reviewed journals and reported at relevant national and international conferences. TRIAL REGISTRATION NUMBER ChiCTR1900027648; Pre-results.

Abstract
Human milk provides not only ideal nutrition for infant development but also immunologic factors to protect from infection and inflammation. For the newborn preterm infant, the natural delivery of milk is not attainable, and instead pumped maternal milk, donor human milk, and human milk fortification are mainstays of clinical care. Current research demonstrates a decreased risk of necrotizing enterocolitis with maternal milk and donor human milk when individually compared to formula and with a complete human milk diet of maternal milk supplemented with donor human milk. The incidence of severe retinopathy of prematurity is decreased with an exclusive human milk diet, and this decrease is more pronounced with human milk-based compared to bovine milk-based human milk fortifier. The incidence of other morbidities such as late-onset sepsis and bronchopulmonary dysplasia is decreased with higher dose of human milk though significant differences are not apparent in exclusive human milk diet studies.

Abstract
PURPOSE This study aimed to evaluate the effect of delayed lactogenesis Ⅱ on early milk volume in mothers expressing milk for their preterm infants. METHODS 142 mothers with preterm infants participated in a longitudinal cohort study, the milk volumes over 14 days postpartum between mothers with delayed lactogenesis Ⅱ (≥ 72 hours) and mothers with non-delayed lactogenesis Ⅱ(< 72 hours) were compared using Wilcoxon's rank sum tests. RESULTS The prevalence of delayed lactogenesisⅡ among mothers of preterm infants was 36.0% (36/100). There existed negative correlations between the onset of lactogenesis Ⅱ and the daily milk volumes( rs = -0.525∼-0.354, p = .002 ∼ p < .001). The milk volumes in every 24-hour of the 14 days postpartum in delayed group were significantly less than that in non-delayed group (p = .002 ∼ p < .001). After controlling for the covariates, pregnancy-induced hypertension syndrome, delayed expression initiation, shorter daily sleeping time were found to be the risk factors for delayed lactogenesis Ⅱ. CONCLUSION Delayed lactogenesis Ⅱ was associated with lower milk volume in early postpartum period. Women who were at risk for delayed lactogenesis Ⅱ need targeted interventions and additional support during pregnancy and postpartum.

Abstract
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.

Might the Mothers of Premature Babies Feed Them and Devote Some Milk to the Milk Bank? Int J Pediatr 2018; 2018:3628952. [PMID: 30631373 PMCID: PMC6304568 DOI: 10.1155/2018/3628952] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 09/30/2018] [Accepted: 10/18/2018] [Indexed: 12/18/2022] Open
Abstract
The breast milk is the gold standard food for the feeding of the premature baby: it is the natural way to provide excellent nutritional, immunological, and biological nutriment so as to facilitate a healthy growth and the development of the infants. When the breast milk is not available, the alternative is represented by the donated milk. The mothers of premature infants are important opportunity if we consider the fact that they could devote some milk both because they provide a food which is closer to the needs of the vulnerable category of newborns and because it is, for the mothers, a way to overcome the detachment and the psychological trauma of a premature birth. There are no data on this kind of donation. The aim of the study is to evaluate the contribution of the milk donation to the HMB of CSS by women who gave birth to premature infants of gestational age <35 weeks and to analyze the macronutrient composition of the "preterm" donated milk. The CSS HMB has recruited 659 donors totalling 2236 liters of donated milk over a period of 7 years. 38 donors (5.7%) gave birth to a gestational age <35 weeks. Almost 20% of the donated milk comes from mothers of premature babies and this is a very important fact because it shows the huge potential belonging to this category of mothers. Taking into account the parameter regarding the birth weight, it was found that VLBW mothers contributed for 56% to preterm donation while ELBW mothers contributed for 41%. By evaluating the variable gestational age, about 40% of the average total donation derives from mothers who gave birth before the 25 weeks, while a contribution of 46% is attributable to the category of newborns with a GA between 25 and 32 weeks. Besides, some other exceptional examples can be outlined. Regarding the correlation analysis DM resulted in negative correlation with GA weeks (r=-0.31, p=0.058) and with BW g (r=-0.30, p=0.068) achieving values which are very close to the significance. The comparison between the donor volume averages of the preterm and full-term groups is statistically significant. The composition data are in line with the literature: there is an increase by 18 % in the protein component of the milk deriving from the mothers of the premature infants; the gap in carbohydrates is less significant (5-6%) and the gap in calories is similarly low being only 2% higher than the single donor milk and 11% more than the pooled milk. The data on the lipids line up to single donor term milk, while it grows by 24% compared to the pooled one. The study shows that even at very low or extreme gestational age it is possible to obtain an appropriate production of breast milk. This awareness becomes a fundamental starting point for the activation in a standardized way of all the strategies of promotion and support of food that have proven effective with the HM in NICU.

Abstract
A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Abstract
BACKGROUND More than 85% of contemporary lactating women in the United States express their milk at least sometimes. Some produce milk exclusively through pumping. We characterized women who pumped but never fed at the breast and compared their infant feeding practices with those of women who fed at the breast with or without pumping. SUBJECTS AND METHODS Study participants were those delivered at Ohio State University Wexner Medical Center in 2011 and completed a questionnaire at 12 months postpartum (n = 478). We used bivariate and multivariate approaches (survival analysis) to compare women who pumped but never fed at the breast with women who fed at the breast with or without pumping. RESULTS Women (n = 33, 6.9%) who pumped but never fed at the breast comprised a diverse group but were more likely to have delivered preterm and were of lower socioeconomic status on average. They initiated pumping and formula feeding earlier (median = day 1 after delivery) and were more likely to report difficulty making enough milk compared with women who fed at the breast with or without pumping. They had much shorter total duration of milk production (adjusted hazard ratio = 3.3, 95% confidence interval: 2.1, 5.2) after controlling for clinical and sociodemographic confounders. CONCLUSIONS Pumping without feeding at the breast is associated with shorter milk feeding duration and earlier introduction of formula compared with feeding at the breast with or without pumping. Establishing feeding at the breast, rather than exclusive pumping, may be important for achieving human milk feeding goals.

Increase in Weight in Low Birth Weight and Very Low Birth Weight Infants Fed Fortified Breast Milk versus Formula Milk: A Retrospective Cohort Study. Nutrients 2017; 9:nu9050520. [PMID: 28531098 PMCID: PMC5452250 DOI: 10.3390/nu9050520] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2017] [Revised: 05/12/2017] [Accepted: 05/18/2017] [Indexed: 11/18/2022] Open
Abstract
There has been a dramatic rise in preterm births in developed countries owing to changes in clinical practices and greater use of assisted reproductive techniques. However, few studies have examined the growth and outcomes of preterm infants according to the type of feeding (with fortified breast milk or formula). The purpose of this study was to examine the effect of breast milk feedings and formula on the growth and short-term outcomes of preterm infants in Hong Kong. In a single-center retrospective cohort study, we included 642 preterm infants at gestational age <37 weeks with birth weights <2200 g. According to World Health Organization criteria, 466 were classified as low birth weight (LBW) infants (≥1500 g and <2200 g) and 176 were classified as very low birth weight (VLBW) infants (<1500 g). The mothers of approximately 80% of VLBW infants and 60% LBW infants initiated breast milk feeding. When compared with no breast milk intake, LBW infants that received breast milk were significantly more likely to have growth z-scores closer to the median of the reference population on admission and experienced slower weight gain from birth to discharge. When breast milk was categorized by percent of total enteral intake, significant differences were seen among LBW infants, with lower percentages of small-for-gestational-age (SGA) status at discharge with increased proportions of breast milk intake. Our results suggest that LBW infants fed breast milk had better growth z-scores and lower SGA status at discharge compared with those predominately fed preterm formula.

Abstract
BACKGROUND Breastfeeding is important, however not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on milk composition, contamination and costs of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 March 2016), handsearched relevant journals and conference proceedings, and contacted experts in the field to seek additional published or unpublished studies. We also examined reference lists of all relevant retrieved papers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS This updated review includes 41 trials involving 2293 participants, with 22 trials involving 1339 participants contributing data for analysis. Twenty-six of the trials referred to mothers of infants in neonatal units (n = 1547) and 14 to mothers of healthy infants at home (n = 730), with one trial containing mothers of both neonatal and healthy older infants (n = 16). Eleven trials compared one or more types of pump versus hand expression and 14 studies compared one type of pump versus another type of pump, with three of these studies comparing both hand expression and pump types. Twenty studies compared a specific protocol or adjunct behaviour including sequential versus simultaneous pumping protocols, pumping frequency, provision of an education and support intervention, relaxation, breast massage, combining hand expression with pumping and a breast cleansing protocol.Due to heterogeneity in participants, interventions, and outcomes measured or reported, we were unable to pool findings for most of the specified outcomes. It was not possible therefore to produce a 'Summary of findings' table in this update. Most of the included results were derived from single studies. Trials took place in 14 countries under a variety of circumstances and were published from 1982 to 2015. Sixteen of the 30 trials that evaluated pumps or products had support from the manufacturers. The risk of bias of the included studies was variable. Primary outcomesOnly one of the 17 studies examining maternal satisfaction/acceptability with the method or adjunct behaviour provided data suitable for analysis. In this study, self-efficacy was assessed by asking mothers if they agreed or disagreed with the following statement: 'I don't want anyone to see me (hand expressing/pumping)'. The study found that mothers who were using the electric pump were more likely to agree with the statement compared to mothers hand expressing, (mean difference (MD) 0.70, 95% confidence interval (CI) 0.15 to 1.25; P = 0.01, participants = 68). Mothers who were hand expressing reported that the instructions for expression were clearer compared to the electric pump, (MD -0.40, 95% CI -0.75 to -0.05; P = 0.02, participants = 68). Descriptive reporting of satisfaction in the other studies varied in the measures used, did not indicate a clear preference for one pump type, although there was satisfaction with some relaxation and support interventions.We found no clinically significant differences between methods related to contamination of the milk that compared any type of pump to hand expression (risk ratio (RR) 1.13, 95% CI 0.79 to 1.61; P = 0.51, participants = 28), manual pump compared to hand expression, (MD 0.20, 95% CI -0.18 to 0.58; P = 0.30, participants = 142) a large electric pump compared to hand expression (MD 0.10, 95% CI -0.29 to 0.49; P = 0.61, participants = 123), or a large electric pump compared to a manual pump (MD -0.10, 95% CI -0.46 to 0.26; P = 0.59, participants = 141).The level of maternal breast or nipple pain or damage was similar in comparisons of a large electric pump to hand expression (MD 0.02, 95% CI -0.67 to 0.71; P = 0.96, participants = 68). A study comparing a manual and large electric pump, reported sore nipples in 7% for both groups and engorgement in 4% using a manual pump versus 6% using an electric pump; and in one study no nipple damage was reported in the hand-expression group, and one case of nipple damage in each of the manual pump and the large electric pump groups.One study examined adverse effects on infants, however as the infants did not all receive their mothers' expressed milk, we have not included the results. Secondary outcomesThe quantity of expressed milk obtained was increased, in some studies by a clinically significant amount, in interventions involving relaxation, music, warmth, massage, initiation of pumping, increased frequency of pumping and suitable breast shield size. Support programmes and simultaneous compared to sequential pumping did not show a difference in milk obtained. No pump consistently increased the milk volume obtained significantly.In relation to nutrient quality, hand expression or a large electric pump were found to provide higher protein than a manual pump, and hand expression provided higher sodium and lower potassium compared to a large electric pump or a manual pump. Fat content was higher with breast massage when pumping; no evidence of difference was found for energy content between methods.No consistent effect was found related to prolactin change or effect on oxytocin release with pump type or method. Economic aspects were not reported. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low-cost interventions including initiation of milk expression sooner after birth when not feeding at the breast, relaxation, massage, warming the breasts, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Variation in nutrient content across methods may be relevant to some infants. Small sample sizes, large standard deviations, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings. Independently funded research is needed for more trials on hand expression, relaxation and other techniques that do not have a commercial potential.
