- Abstract
Fortified human milk is the first choice for preterm infants. Although individualized fortification is recommended, the optimal method for this population remains uncertain. We conducted a comparative study assessing the growth effects of adjusted (AF) and targeted fortification (TF) in extremely low birth weight (ELBW) infants. This single-center, randomized, controlled clinical trial was conducted at a tertiary neonatal unit in Spain. Eligible participants were premature infants with a birthweight of <1000 g exclusively fed with human milk. A total of 38 patients were enrolled, 15 of them randomized to AF group and 23 to TF group. AF was based on blood urea nitrogen (BUN) concentration and TF on human milk analysis. The primary outcome was weight gain velocity (g/kg/day). No significant differences were found in weight gain velocity at 28 days, at 36 weeks of postmenstrual age, at discharge, nor during the intervention. Protein intake was significantly higher in the AF group (5.02 g/kg/day vs. 4.48 g/kg/day, p = 0.001). No differences were found in the lipid, carbohydrate, and energy intake; in the weight z score change between the different time points; nor in the length and head circumference growth. Both AF and TF are comparable methods of fortification and provide the appropriate growth rate in ELBW infants.

- Abstract
Background: The aim of this study is to determine the effect of music-assisted kangaroo care, applied to mothers with premature babies in the intensive care unit on the amount of breast milk, the initiation time of breastfeeding, and the level of anxiety. Methods: The study was carried out with mothers whose premature babies were hospitalized in the neonatal intensive care unit. The sample size of the study was 99 mothers. Results: 85.5% of the mothers were aged >35 years, 30.1% were high school graduates, 38.6% had equal income and expenses and 77.1% had a cesarean section. The state and trait anxiety levels of the mothers in the music assisted kangaroo care (MAKC), kangaroo care (KC), and control (C) groups decreased after the first day according to the follow-up times. The trait anxiety levels of the mothers in the MAKC group experienced on the first and sixth days were lower than those of the mothers in the KC and C groups, with the statistically significant differences ( p < 0.05). It was found that the mothers in the MAKC group started breastfeeding earlier than those in the KC and C groups, and the difference was statistically significant ( p < 0.05). Conclusion: A significant difference was found between the MAKC and KC groups and the control group in terms of an increase in the amount of milk, a decrease in trait anxiety levels, and early initiation of breastfeeding ( p < 0.05).

- Abstract
Background: Breast milk is vital for the growth and development of preterm infants. However, in Neonatal Intensive Care Units (NICUs), mothers often encounter significant challenges in breastfeeding. Objective: This study aims to systematically evaluate the barriers to breastfeeding in NICUs, thereby providing evidence-based support for clinical practices. Methods: A comprehensive search was conducted in the Cochrane Library, PubMed, Web of Science, Embase, and Scopus databases, up to September 2023. Meta-analysis was performed using Stata 15.0, applying fixed or random effects models to calculate odds ratios (OR) and their 95% confidence intervals (CI). Study quality was assessed using the Newcastle-Ottawa Scale for cases and cohorts and the Agency for Healthcare Research and Quality standards for cross-sectional studies. Heterogeneity was evaluated using Cochran's chi-squared test (Cochran's Q) and I
2 statistics, and publication bias was assessed through funnel plots and symmetry tests. Results: A total of 32 studies were included, encompassing 96,053 preterm infants. The main barriers to breastfeeding in preterm infants included: low gestational age (OR = 1.36, 95% CI: 1.06-1.75), lower maternal education (OR = 1.64, 95% CI: 1.39-1.93), insufficient breast milk (OR = 2.09, 95% CI: 1.39-1.93), multiple births (OR = 1.615, 95% CI: 1.18-2.210), smoking (OR = 2.906, 95% CI: 2.239-3.771), and single motherhood (OR = 1.439, 95% CI: 1.251-1.654). Conclusion: This study underscores the need for individualized breastfeeding support strategies in NICUs, taking into account the diverse backgrounds of mothers. Future research should focus on unraveling the underlying mechanisms affecting breastfeeding in preterm infants, with the goal of enhancing breastfeeding rates and improving developmental outcomes.- Published

- Abstract
Objective: Processing speed is suboptimal among preterm-born children which is of concern as it is a foundational skill supporting higher-level cognitive functions. The study objective was to evaluate associations between early-life nutrition and processing speed in childhood., Methods: Macronutrient and human milk (mother's own, donor) intakes from 137 children born preterm with very low birth weight enrolled in a nutrition feeding trial were included. Processing speed was evaluated at age 5 using the Wechsler Preschool and Primary Scale of Intelligence-fourth edition Processing Speed Index. Associations between early-life nutrition and processing speed were explored through linear regression., Results: Children had a mean (standard deviation [SD]) birth gestational age of 28.1 (2.5) weeks, weight of 1036 (260) g and 52% were male. The mean (SD) assessment age was 5.7 (0.2) years. Sex-dependent relationships were identified between first postnatal month protein, lipid and energy intakes and processing speed at 5 years. For females, lower protein (per 0.1 g/kg/d: -0.88, 95% confidence interval [CI]: -1.53, -0.23; p = 0.01) and energy (per 10 kcal/kg/d: -2.38, 95% CI: -4.70, -0.05; p = 0.03) intakes were related to higher processing speed scores. Mother's milk provision was positively associated (per 10% increase: 0.80, 95% CI: 0.22, 1.37; p = 0.01) and donor milk was negatively associated (per 10% increase: -1.15, 95% CI: -2.22, -0.08; p = 0.04) with processing speed scores; no sex differences were observed., Conclusions: First postnatal month nutrition was related to processing speed at age 5 in children born preterm with very low birth weight. Early-life nutrition that supports processing speed may be leveraged to improve later cognitive outcomes for this vulnerable population., (© 2024 The Authors.

- Abstract
Objective: To identify the type of feeding and analyze the sociodemographic and clinical factors associated with exclusive breastfeeding at hospital discharge, in the first and in the last follow-up visit of the third stage of the Kangaroo Mother Care among infants admitted to the kangaroo unit., Method: Longitudinal and retrospective study. A total of 186 infants of gestational age <37 weeks admitted to the kangaroo unit in 2018 and 2019 was included. Data collected from medical records and subjected to inferential analysis and the Poisson regression model (P < 0.05)., Results: Exclusive breastfeeding rate was 73.1% at discharge, with a drop at the last follow-up visit (68.1%). At discharge, there was a greater probability of exclusive breastfeeding in younger mothers, with higher education, infants born with higher birth weight and who received exclusive human milk during hospitalization; in the first follow-up visit, in a younger mother and infant who received only human milk during hospitalization; and in the last follow-up visit, a young mother, infant who received only human milk and suckled at the breast for the first time in the kangaroo unit., Conclusion: Most infants hospitalized in the second stage of the Kangaroo Mother Care were exclusively breastfed and presented maternal and clinical factors related to breastfeeding. This fact can help manage the challenges of the method and promote breastfeeding.

- Abstract
The nutrition of preterm infants remains contaminated by wrong beliefs that reflect inexactitudes and perpetuate old practices. In this narrative review, we report current evidence in preterm neonates and in preterm neonates undergoing surgery. Convictions that necrotizing enterocolitis is reduced by the delay in introducing enteral feeding, a slow advancement in enteral feeds, and the systematic control of residual gastric volumes, should be abandoned. On the contrary, these practices prolong the time to reach full enteral feeding. The length of parenteral nutrition should be as short as possible to reduce the infectious risk. Intrauterine growth restriction, hemodynamic and respiratory instability, and patent ductus arteriosus should be considered in advancing enteral feeds, but they must not translate into prolonged fasting, which can be equally dangerous. Clinicians should also keep in mind the risk of refeeding syndrome in case of high amino acid intake and inadequate electrolyte supply, closely monitoring them. Conversely, when preterm infants undergo surgery, nutritional strategies are still based on retrospective studies and opinions rather than on randomized controlled trials. Finally, this review also highlights how the use of adequately fortified human milk is strongly recommended, as it offers unique benefits for immune and gastrointestinal health and neurodevelopmental outcomes.

- Abstract
Background: Preterm infants (born before 37 weeks' gestation) are often unable to co-ordinate sucking, swallowing, and breathing for oral feeding because of their immaturity. In such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feeding intolerance is common and can delay attainment of full enteral and sucking feeds, prolonging the need for nutritional support and the hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption. However, during tube feeding, milk bypasses the nasal and oral cavities, limiting exposure to the smell and taste of milk. Provision of the smell and taste of milk with tube feeds offers a non-invasive and low-cost intervention that, if effective in accelerating the transition to enteral feeds and subsequently to sucking feeds, would bring considerable advantages to infants, their families, and healthcare systems., Objectives: To assess whether exposure to the smell or taste (or both) of breastmilk or formula administered with tube feeds can accelerate the transition to full sucking feeds without adverse effects in preterm infants., Search Methods: We conducted searches in CENTRAL, MEDLINE, Embase, CINAHL, and Epistemonikos to 26 April 2023. We also searched clinical trial databases and conference proceedings., Selection Criteria: We included randomised and quasi-randomised studies that evaluated exposure versus no exposure to the smell or taste of milk (or both) immediately before or at the time of tube feeds., Data Collection and Analysis: Two review authors independently selected studies, assessed risk of bias, and extracted data according to Cochrane Neonatal methodology. We performed meta-analyses using risk ratios (RRs) for dichotomous data and mean differences (MDs) for continuous data, with their respective 95% confidence intervals (CIs). We used GRADE to assess the certainty of evidence., Main Results: We included eight studies (1277 preterm infants). Seven studies (1244 infants) contributed data for meta-analysis. The evidence suggests that exposure to the smell and taste of milk with tube feeds has little to no effect on time taken to reach full sucking feeds (MD -1.07 days, 95% CI -2.63 to 0.50; 3 studies, 662 infants; very low-certainty evidence). Two studies reported no adverse effects related to the intervention. The intervention may have little to no effect on duration of parenteral nutrition (MD 0.23 days, 95% CI -0.24 to 0.71; 3 studies, 977 infants; low-certainty evidence), time to reach full enteral feeds (MD -0.16 days, 95% CI -0.45 to 0.12; 1 study, 736 infants; very low-certainty evidence) or risk of necrotising enterocolitis (RR 0.93, 95% CI 0.47 to 1.84; 2 studies, 435 infants; low-certainty evidence), although the evidence for time to reach full enteral feeds is very uncertain. Exposure to the smell and taste of milk with tube feeds probably has little to no effect on risk of late infection (RR 1.14, 95% CI 0.74 to 1.75; 2 studies, 436 infants; moderate-certainty evidence). There were no data available to assess feeding intolerance. The included studies had small sample sizes and methodological limitations, including unclear or lack of randomisation (four studies), lack of blinding of participants and personnel (five studies), unclear or lack of blinding of the outcome assessor (all eight studies), and different inclusion criteria and methods of administering the interventions., Authors' Conclusions: The results of our meta-analyses suggest that exposure to the smell and taste of milk with tube feeds may have little to no effect on time to reach full sucking feeds and time to reach full enteral feeds. We found no clear difference between exposure and no exposure to the smell or taste of milk on safety outcomes (adverse effects, necrotising enterocolitis, and late infection). Results from one ongoing study and two studies awaiting classification may alter the conclusions of this review. Future research should examine the effect of exposing preterm infants to the smell and taste of milk with tube feeds on health outcomes during hospitalisation, such as attainment of feeding skills, safety, feed tolerance, infection, and growth. Future studies should be powered to detect the effect of the intervention in infants of different gestational ages and on each sex separately. It is also important to determine the optimal method, frequency, and duration of exposure., (Copyright © 2024 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd.)

- Abstract
Objective: Evaluate a single center quality improvement (QI) collaborative designed to increase the provision of mother's own milk (MOM) at discharge to premature infants through evidence-based practices while targeting perinatal health disparities., Design: This QI initiative was designed for preterm infants admitted to a single-center NICU within 24 h of life. Interventions were implemented between March 2022 and June 2022. MOM provision rates were compared between baseline (August 2021-February 2022), and after interventions (March 2022-December 2022)., Results: The percentage of mothers who discontinued pumping during the infant hospitalization decreased from 49% to 35% (p < 0.01). Infant discharge diet with MOM improved from 36% to 58% (p < 0.001). Pump frequency at two weeks increased from 4.0 ± 2.6 to 5.1 ± 2.4 (p = 0.026)., Conclusion: Our collaborative increased the percentage of preterm infants receiving MOM at discharge and reduced the number of mothers who discontinue pumping during the NICU hospitalization., (© 2023.

- Abstract
Background: In very low birth weight (VLBW) infants, human milk cream added to standard human milk fortification is used to improve growth. This study aimed to evaluate the impact of cream supplement on the intestinal microbiome of VLBW infants., Methods: Whole genome shotgun sequencing was performed on stool (n = 57) collected from a cohort of 23 infants weighing 500-1250 grams (control = 12, cream = 11). Both groups received an exclusive human milk diet (mother's own milk, donor human milk, and donor human milk-derived fortifier) with the cream group receiving an additional 2 kcal/oz cream at 100 mL/kg/day of fortified feeds and then 4 kcal/oz if poor growth., Results: While there were no significant differences in alpha diversity, infants receiving cream significantly differed from infants in the control group in beta diversity. Cream group samples had significantly higher prevalence of Proteobacteria and significantly lower Firmicutes compared to control group. Klebsiella species dominated the microbiota of cream-exposed infants, along with bacterial pathways involved in lipid metabolism and metabolism of cofactors and amino acids., Conclusions: Cream supplementation significantly altered composition of the intestinal microbiome of VLBW infants to favor increased prevalence of Proteobacteria and functional gene content associated with these bacteria., Impact: We report changes to the intestinal microbiome associated with administration of human milk cream; a novel supplement used to improve growth rates of preterm very low birth weight infants. Since little is known about the impact of cream on intestinal microbiota composition of very low birth weight infants, our study provides valuable insight on the effects of diet on the microbiome of this population. Dietary supplements administered to preterm infants in neonatal intensive care units have the potential to influence the intestinal microbiome composition which may affect overall health status of the infant., (© 2024.

- Abstract
Objective: We aimed to study donor milk (DM) supplementation when mother's own milk (MOM) was unavailable in term and late preterm infants (LPIs) admitted to the neonatal intensive care unit (NICU). We hypothesized that this study would be feasible, defined by the rate of consent, diet adherence, and study completion. We further hypothesized that compared with formula supplementation, DM supplementation, for no longer than 7 days from birth, would be associated with an increase in breastfeeding attempts and the percentage of MOM (MOM%) without adversely affecting growth. Breastfeeding attempts and MOM% were assessed over 48 hours at the end of the intervention, which was defined as NICU discharge or at the end of supplementation, whichever came sooner., Study Design: This was a pilot study ( n = 32). Infants with a gestational age > 34 weeks admitted to the NICU were included. Infants were randomized to one of two groups: human milk (MOM + DM) or formula (MOM + F)., Results: The consent rate was 52%. Adherence to the study diet was 97%, and completion was 100%. When the MOM + DM group was compared with the MOM + F group, there was no difference in breastfeeding attempts (median [interquartile range]: 3.5 [1.5-6] vs. 1.5 [0.5-4] times, p = 0.1) or MOM% (60 vs. 59%, p = 0.9). Weight and length at multiple time points were similar when the groups were compared., Conclusion: A study randomizing term and LPIs in the NICU to DM or formula when MOM was unavailable is feasible. It remains unclear if DM improves breastfeeding success in this population., Key Points: · A study that randomizes term and late preterm infants in the NICU to DM or formula supplementation when mother's own milk is not available is feasible.. · It remains unclear if DM compared to formula supplementation improves direct breastfeeding.. · In general, growth was similar in infants who received DM or formula as a supplement.., Competing Interests: K.L.C. has received research support from Fresenius Kabi.

- Abstract
Background: Raw, never stored or pasteurized mother's own milk (MOM) is not always available to feed preterm infants; however, storage and pasteurization of MOM diminishes some bioactive components. It can be difficult to feed raw MOM to preterm infants due to transportation and storage of small volumes that might be pumped away from the infant, and a concern that they might harbor bacteria. However, the higher availability of bioactive components in raw MOM may provide benefits to preterm infants compared to frozen or pasteurized MOM., Research Aim: To systematically review and summarize the results of studies on feeding raw MOM versus frozen or pasteurized MOM to preterm infants born at less than 37 weeks of gestation., Methods: Four databases were searched (Cochrane, Embase, Ovid MEDLINE, and Web of Science) for this systematic review. Of 542 studies identified, nine met inclusion criteria and were critically evaluated using the quality assessment tool for quantitative studies by the Effective Public Health Practice Project. Studies were organized using the Breastfeeding Challenges Facing Preterm Mother-Infant Dyads theoretical framework., Results: Included studies evaluated the outcomes of preterm infants fed raw versus pasteurized MOM ( n = 7, 77.8%) or raw versus frozen MOM ( n = 2, 22.2%). Researchers found that raw MOM did not increase infant infections and may have improved health and growth outcomes for study participants., Conclusion: There is laboratory evidence supporting the safety and efficacy of the use of raw MOM for preterm infants. A raw MOM diet is recommended for preterm infants by professional organizations. Despite this, it may not be universally prioritized and could require purposeful implementation by each institution. Further research is needed to pursue the potential benefits of a raw MOM diet for preterm infants., Competing Interests: Disclosures and Conflicts of InterestThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objective: Mothers of preterm infants face unique challenges in establishing milk supply. We hypothesized that daily meditation practice while pumping would increase milk volume., Study Design: This was a randomized control trial examining the effect of meditation on the breastmilk supply of women delivering preterm infants. The meditation group engaged in daily use of a mindfulness-focused meditation app in addition to routine lactation support. The primary outcome was mean breastmilk volume on the infant's nineth day of life. Secondary outcomes included use of lactation-promoting behaviors, continuation of breastfeeding, and measures of mental health and breastfeeding self-efficacy by validated questionnaires. In addition to the intention to treat analysis, a per protocol analysis examined the association of frequent meditation with these breastfeeding and mental health outcomes., Results: A total of 60 women were analyzed. Mean milk volume was 647.1 ± 467.8 mL in the meditation group and 514.9 ± 393.5 mL in the routine care group ( p = 0.27). Median number of pumping sessions was 7 (interquartile range [IQR] 5-8) in the meditation group, compared to 6 (IQR 4-7) in the routine care group ( p = 0.11). Other lactation-promoting behaviors, breastfeeding continuation, and questionnaire scores were similar.Adjusting for confounders, we found an increase in breastmilk production of 223.2 mL (95% CI 98.8-347.5, p = 0.001) and in pumping episodes by 0.93 (95% CI 0.16-1.70, p = 0.020) associated with frequent meditation. Skin-to-skin contact was increased to 100% ( p = 0.006) among women who meditated seven or more times. Adjusted odds of a clinically significant Edinburgh Postnatal Depression Scale score of >9 was 0.057 (95% CI 0.0014-0.711, p = 0.023) with frequent meditation., Conclusion: Breastmilk production was similar in mothers practicing meditation compared to those receiving routine lactation support. For women engaging in frequent mediation, there may be an effect in establishing breastmilk supply and reduction of depression symptoms., Key Points: · Breastmilk is not increased for neonatal intensive care unit (NICU) moms asked to engage in meditation.. · Maternal mental health is not improved among NICU moms asked to meditate.. · However, higher-frequency meditation is associated with increased milk volume and lower odds of high scores on depression screening.., Competing Interests: None declared., (Thieme.

- Abstract
Purpose of Review: For many decades, docosahexaenoic acid (DHA) supplementation was tested in premature infants to achieve an intake equivalent to the average level in breast milk, but this approach has led to conflicting results in terms of development and health outcomes. Higher doses of DHA closer to fetal accumulation may be needed., Recent Findings: The efficacy of DHA supplementation for preterm infants at a dose equivalent to the estimated fetal accumulation rate is still under investigation, but this may be a promising approach, especially in conjunction with arachidonic acid supplementation. Current data suggest benefit for some outcomes, such as brain maturation, long-term cognitive function, and the prevention of retinopathy of prematurity. The possibility that supplementation with highly unsaturated oils increases the risk of neonatal morbidities should not be ruled out, but current meta-analyzes do not support a significant risk., Summary: The published literature supports a DHA intake in preterm infants that is closer to the fetal accumulation rate than the average breast milk content. Supplementation with DHA at this level in combination with arachidonic acid is currently being investigated and appears promising., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Breast-feeding is associated with fewer comorbidities in very-low-birth-weight (VLBW) preterm infants. Bronchopulmonary dysplasia (BPD) of VLBW infants is a multifactorial pathology in which nutritional aspects may be of special importance. The aim of this study is to determine, in a cohort of VLBW infants, whether breast milk nutrition is associated with a reduced prevalence and severity of BPD. A retrospective study was conducted to record the intake of mother's own milk (MOM), pasteurised donor human milk or preterm formula milk in the first 2 weeks of postnatal life of 566 VLBW newborns at our hospital during the period January 2008-December 2021. After applying the relevant exclusion criteria, data for 489 VLBW infants were analysed; 195 developed some degree of BPD. Moderate or severe BPD is associated with less weight gain. Moreover, the preferential ingestion of breast milk in the first and second postnatal weeks had effects associated with lower OR for BPD, which were statistically demonstrable for mild (OR 0·16; 95 % CI 0·03, 0·71) and severe (OR 0·08; 95 % CI 0·009, 0·91) BPD. Breast-feeding during the first weeks of postnatal life is associated with a reduced prevalence of BPD, which is frequently associated with less weight gain as a result of greater respiratory effort with greater energy expenditure.

- Abstract
Background: Most moderate-to-late-preterm infants need nutritional support until they are feeding exclusively on their mother's breast milk. Evidence to guide nutrition strategies for these infants is lacking., Methods: We conducted a multicenter, factorial, randomized trial involving infants born at 32 weeks 0 days' to 35 weeks 6 days' gestation who had intravenous access and whose mothers intended to breast-feed. Each infant was assigned to three interventions or their comparators: intravenous amino acid solution (parenteral nutrition) or dextrose solution until full feeding with milk was established; milk supplement given when maternal milk was insufficient or mother's breast milk exclusively with no supplementation; and taste and smell exposure before gastric-tube feeding or no taste and smell exposure. The primary outcome for the parenteral nutrition and the milk supplement interventions was the body-fat percentage at 4 months of corrected gestational age, and the primary outcome for the taste and smell intervention was the time to full enteral feeding (150 ml per kilogram of body weight per day or exclusive breast-feeding)., Results: A total of 532 infants (291 boys [55%]) were included in the trial. The mean (±SD) body-fat percentage at 4 months was similar among the infants who received parenteral nutrition and those who received dextrose solution (26.0±5.4% vs. 26.2±5.2%; adjusted mean difference, -0.20; 95% confidence interval [CI], -1.32 to 0.92; P = 0.72) and among the infants who received milk supplement and those who received mother's breast milk exclusively (26.3±5.3% vs. 25.8±5.4%; adjusted mean difference, 0.65; 95% CI, -0.45 to 1.74; P = 0.25). The time to full enteral feeding was similar among the infants who were exposed to taste and smell and those who were not (5.8±1.5 vs. 5.7±1.9 days; P = 0.59). Secondary outcomes were similar across interventions. Serious adverse events occurred in one infant., Conclusions: This trial of routine nutrition interventions to support moderate-to-late-preterm infants until full nutrition with mother's breast milk was possible did not show any effects on the time to full enteral feeding or on body composition at 4 months of corrected gestational age.

- Abstract
Objective: The aim of this study was to explore the effect of in-hospital breast milk intake on the development of early gut microbiota in preterm infants in two dimensions: longitudinal over time and cross-sectional between groups., Methods: Researchers collected preterm infants' general data baseline characteristics, recorded their daily breast milk intake, probiotics, and antibiotics use, and collected their stool specimens at 1st week, 2 nd week, 3rd week and 4th week after birth. The researchers analyzed the effect of breast milk on gut microbiota of preterm infants by bioinformatics methods of intra-group longitudinal variation of gut microbiota structure and diversity in preterm infants and cross-sectional differences between >70 % in-hospital breast milk intake (BM) group and ≤70 % (PF) group., Results: A total of 60 preterm infants were included in this study, and a total of 213 stool specimens were retained. BM had statistically different Shannon and Simpson indices between the first and fourth week after admission (P < 0.05), both of them showed a lower diversity in the later week than in the previous week. The Shannon index and Simpson index of BM from week 3 onwards were statistically different from PF (P < 0.05), and the Shannon index and Simpson index of BM were lower than those of PF. Significantly statistical differences (P < 0.05) were found in the beta diversity of gut microbiota in preterm infants as time progressed, and both showed a lower beta diversity in the later week than in the preceding week. The dominant taxa of PF in the first postnatal week were Bifidobacterium animalis, etc., the dominant taxa of BM in the third postnatal week were Clostridium_sensu_stricto _1, etc. CONCLUSIONS: The development and evolution of gut microbiota in preterm infants' in-hospital period was a continuous, non-random process, and similar trends in species composition and changes in gut microbes emerged in preterm infants with different ratio of breast milk intake. In the NICU setting, alpha diversity was lower in preterm infants in the >70 % breast milk intake group than in the ≤70 % group when compared between groups at the same time, which may be related to delayed maturation of gut microbes and represents a more developmental gut time window., Competing Interests: Conflict of interest The authors declare no conflicts of interest., (Copyright © 2024 European Society for Clinical Nutrition and Metabolism.

- Abstract
Importance: Delayed meconium evacuation and delayed achievement of full enteral feeding among premature infants are associated with poor short- and long-term outcomes. Identifying a more effective and safer enema for meconium evacuation is imperative for improving neonatal care., Objective: To examine whether breast milk enemas can shorten the time to complete meconium evacuation and achievement of full enteral feeding for preterm infants., Design, Setting, and Participants: This randomized, open-label, parallel-group, single-center clinical trial was conducted from September 1, 2019, to September 30, 2022, among 286 preterm infants with a gestational age of 23 to 30 weeks in the neonatal ward of the Shengjing Hospital of China Medical University in Shenyang., Interventions: Preterm infants were randomly assigned to receive either breast milk enemas or normal saline enemas 48 hours after birth., Main Outcome and Measures: The primary outcomes were time to complete meconium evacuation and time to achieve full enteral feeding. Secondary outcomes were duration of hospitalization, weight at discharge, and duration of total parenteral nutrition. Intention-to-treat and per-protocol analyses were conducted., Results: In total, 286 preterm infants (mean [SD] gestational age, 198.8 [7.9] days; 166 boys [58.0%]) were eligible and included in this study. A total of 145 infants were randomized to the normal saline group, and 141 were randomized to the breast milk group. The time to achieve complete meconium evacuation was significantly shorter in the breast milk group than in the normal saline group (-2.2 days; 95% CI, -3.2 to -1.2 days). The time to achieve full enteral feeding was also significantly shorter in the breast milk group than in the normal saline group (-4.6 days; 95% CI, -8.0 to -1.2 days). The duration of total parenteral nutrition was significantly shorter in the breast milk group than in the normal saline group (-4.6 days; 95% CI, -8.6 to -1.0 days). There were no clinically notable differences in any other secondary or safety outcomes between the 2 groups., Conclusions and Relevance: In this randomized clinical trial testing the effects of breast milk enema on meconium evacuation, breast milk reduced the time to achieve complete meconium evacuation and achieve full enteral feeding for preterm infants with a gestational age of 23 to 30 weeks. Subgroup analyses highlight the need for tailored interventions based on gestational age considerations., Trial Registration: isrctn.org Identifier: ISRCTN17847514.

- Abstract
Introduction: Fortified expressed breast milk (FEBM) is a standard of care for premature and low birth weight neonates, but comes with an elevated risk of a rare but re-emergent pathology called milk curd obstruction (MCO). Little is known about normal sonographic appearances of bowel contents in this feeding setting, making the recognition of abnormalities difficult. Thus, we aimed to describe appearances that may be considered typical pre- and post-fortifier inclusion., Methods: Ten neonates of <32 weeks' gestation or a birth weight of <1,800 g recruited from Auckland City Hospital Neonatal Intensive Care between 1/5/2019 and 10/9/2019 received bowel ultrasounds within 24 h before and 10-14 days after starting FEBM. Bowel contents in six abdominal regions were assigned scores of 1-6 based on increasing solidification., Results: Lower gestational age was correlated with more solid contents on the pre-fortifier ultrasound (P = 0.02). Fortifier was significantly associated with increasing solidity, particularly in the left abdomen (P < 0.001). The left lower quadrant and rectum accounted for much of this change (P = 0.012 and P = 0.002). One subject who subsequently developed a clinical picture consistent with early MCO had uniquely demonstrated non-rectal solid contents (score 6). The interobserver kappa score for two assessors was 0.91 (95% CI 0.94-0.99) on still images., Conclusion: This small cohort demonstrated increasing bowel content solidification after breast milk fortification using a novel ultrasound scoring system with good interobserver agreement. Non-rectal solid contents (score 6) appeared atypical. Ultrasound shows promise for its non-irradiating diagnostic utility in the setting of early milk curd disease evaluation of the premature neonate., (© 2024 Royal Australian and New Zealand College of Radiologists.)

- Abstract
Mother's own milk (MOM) is known to decrease complications in preterm infants and when unavailable, it is recommended that preterm very low-birth weight infants be fed donor human milk (DHM). Due to the pasteurization, processing, and lactation stage of donors, DHM does not contain the same nutritional, immunologic, and microbial components as MOM. This review summarizes the differences between MOM and DHM, the potential effects on health outcomes, and the clinical implications of these differences. Finally, implications for research and clinical practice are discussed., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Propose: Introducing early oral feeding in premature infants is important because it supports intestinal maturation and helps prevent infections. In addition, early oral feeding is likely to contribute to improved neurocognitive outcomes in preterm infants. Several holistic therapeutic strategies have been developed to improve feeding skills, food tolerance, and the ability to drink independently, including practices such as early breastfeeding, oral stimulation, and subsequent olfactory stimulation. Based on several studies using olfactory stimulation with food odors (vanilla, breast milk) to promote oral feeding in preterm infants this study was conducted to test the following hypothesis: Does olfactory stimulation with vanilla or milk odor (breast milk or formula) lead to a reduction in the time required for nasogastric tube weaning in premature infants older than 26 + 6 weeks of gestational age? In addition, does it influence secondary outcomes such as length of hospital stay, weight development, and attainment of greater amounts of independently consumed food?, Methods: Premature with complete or partial feeding by gastric tube and without ventilation were included. For this study, 207 infants over 26 + 6 gestational weeks were randomized into three different study groups. Before each feeding, an olfactory presentation was made with milk odor, a vanilla Sniffin' Stick, or a control stick. In the final analysis, 165 infants were included (87 males, 78 females). At the time of randomization, infants were on average 12 ± 9.5 days old., Results: While the influence of vanilla and milk odor did not provide a significant difference from the control for the primary outcome, a secondary analysis showed a significant group difference in the cumulative amount of independently drunk food consumed in the first ten days was the highest amount in the vanilla group. This time period was chosen due to the high dropout rate after the first ten days. In addition, there was a promising significance for earlier hospital discharge for prematurely below 32 weeks of gestation receiving vanilla odor stimulation in comparison to milk odor stimulation., Conclusion: Although the primary outcome of this study (gastric tube removal) did not provide significant results, a significant benefit of vanilla olfactory stimulation for preterm infants was demonstrated in subgroup analysis above milk odor stimulation. Younger preterm infants seem to benefit from the stimulation., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023. Published by Elsevier Inc.)

- Abstract
Background: A common neonatal intensive care unit (NICU) discharge feeding strategy for preterm infants with growth failure who are fed exclusively expressed human milk (EHM) has been to enrich mother's own milk with formula powder or supplement 2-3 feeds per day with formula. However, this strategy displaces human milk from the diet. Our NICU recently adopted the standard practice of adding commercial human milk fortifier (HMF) to human milk feedings after discharge., Objectives: We aimed to compare breastfeeding rates and growth using the aforementioned 2 strategies., Methods: Preterm infants (<34 wk of gestation at birth) exclusively feeding EHM fortified with HMF at 2 weeks before discharge were included in this retrospective study. The HMF group (n = 92) continued fortifying with HMF at home, whereas the historical comparison group (n = 35) received our previous guidance to enrich or supplement using postdischarge formula., Results: Rates of human milk exclusivity after discharge decreased significantly less in the HMF group than those in the historical comparison group (to 83% compared with 39% at the first outpatient visit and 27% compared with 6%, respectively, at the second outpatient visit). Rates of any EHM feedings were also significantly higher in the HMF group. Fenton z-scores for weight, length, and head circumference were not significantly different between the groups., Conclusions: Continuing EHM fortification with HMF after NICU discharge, rather than enriching or supplementing with postdischarge infant formula, increases rates of feeding EHM for ≥3 mo but does not affect growth., Competing Interests: Conflict of interest The authors report no conflicts of interest., (Copyright © 2023 American Society for Nutrition.

- Abstract
Background: Antisecretory Factor (AF) is a protein present in breastmilk that regulates inflammatory processes. We aimed to investigate the level of AF in mothers' own milk (MOM) in relation to sepsis and other neonatal morbidities in preterm infants., Methods: Samples of breastmilk and infant plasma were collected at 1, 4, and 12 weeks after birth from 38 mothers and their 49 infants born before 30 weeks gestation. AF-compleasome in MOM was determined by a sandwich enzyme-linked immunosorbent assay (ELISA) and inflammatory markers in infant plasma by a panel of 92 inflammatory proteins. Neonatal treatments and outcomes were recorded., Results: The level of AF in MOM week 1 was lower for infants with later sepsis compared to no sepsis (p = 0.005). Corrected for nutritional intake of MOM, higher levels of AF decreased the risk for sepsis, OR 0.24. AF in MOM week 1 was negatively correlated to inflammatory proteins in infant plasma week 4, markedly IL-8, which was also associated with infant sepsis. Overall, higher AF levels in MOM was associated with fewer major morbidities of prematurity., Conclusion: Mother's milk containing high levels of antisecretory factor is associated with reduced risk for sepsis and inflammation in preterm infants., Impact: High level of antisecretory factor (AF) in mothers' own milk is associated with less risk for later sepsis in preterm infants. Receiving mothers' milk with low AF levels during the first week after birth is correlated with more inflammatory proteins in infant's plasma 2-4 weeks later. Human breastmilk has anti-inflammatory properties, and antisecretory factor in mothers' own milk is a component of potential importance for infants born preterm. The findings suggest that food supplementation with AF to mothers of preterm infants to increase AF-levels in breastmilk may be a means to decrease the risk of inflammatory morbidities of prematurity., (© 2023.

- Abstract
Late preterm infants have lower breastfeeding rates than term infants, yet few published interventions or guidelines exist to guide hospitals in managing them in the non-intensive nursery setting. Here we describe the development and implementation of an interdisciplinary, hospital-based, breastfeeding support program among late preterm infants not requiring intensive care. The Early Bloomer Program includes an order set applied at birth, immediate lactation consultation, availability of donor milk, parent education on late preterm infants, hand expression teaching and kit including spoon and video link, and daily interdisciplinary team huddles. The program was developed with staff input using Diffusion of Innovation Theory, and implemented first among early adopters before expanding to all postpartum nurses. Nursing staff received education on late preterm infant physiology and feeding, and trainings on the Early Bloomers program through various learning modalities during the year leading up to implementation. To further understand the strengths and weakness of the program, we surveyed nurses ( n = 43). Nurses reported that they were more attentive to the needs of late preterm infants, more confident in their care, and more aware of possible complications and feeding needs. Areas noted in need of improvement included lack of overnight lactation consults and little involvement of labor and delivery staff in the program. The Early Bloomers program increased confidence in care and was well received by nurses. Well-designed clinical studies are needed to identify effective breastfeeding support practices for late preterm infants., Competing Interests: Disclosures and Conflicts of InterestThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Iron supplementation is routinely recommended for breast-milk-fed preterm infants. However, the Canadian Pediatric Society recommends no additional iron supplementation for preterm infants fed primarily with iron-rich formula. Other pediatric societies don't provide specific guidance on supplemental iron for formula-fed preterm infants. This study investigated how feeding type influences iron status of very preterm infants at 4-6-months corrected age (CA). A retrospective cohort study was conducted using a population-based database on all very preterm infants (<31 weeks gestational age) born in Nova Scotia, Canada from 2005-2018. Information about feeding type, iron intake from formula, supplemental iron therapy and iron status at 4-6-months CA was extracted. Iron deficiency (ID) was defined as serum ferritin <20 and <12 µg/L at 4-and 6-months CA, respectively. Of 392 infants, 107 were "breast-milk-fed" (exclusively or partially) and 285 were "not breast-milk-fed" (exclusively fed with iron-rich formula) at 4-6-months CA. Total daily iron intake was higher in the non-breast-milk-fed group (2.6 mg/kg/day versus 2.0 mg/kg/day). Despite this, 36.8% of non-breast-milk-fed infants developed ID versus 20.6% of breast-milk-fed infants. ID is significantly more prevalent in non-breast-milk-fed infants than breast-milk-fed infants despite higher iron intake. This suggests the need to revisit recommendations for iron supplementation in non-breast-milk-fed preterm infants.

- Abstract
While direct at-the-breast feeding is biologically optimal, Neonatal Intensive Care Unit (NICU) admission due to infant immaturity or illness often necessitates the expression and storage of parent's milk. The provision of freshly expressed (never stored) parent's own milk to preterm infants is not widely prioritized, and this article provides an exploration of NICU practices and their implications for feeding premature or ill infants with parent's own milk. In this article, we discuss the potential biological benefits of fresh parent's own milk, highlighting its dynamic components and the changes incurred during storage. Research suggests that fresh milk may offer health advantages over stored milk. The authors advocate for further research, emphasizing the need for standardized definitions. Research is needed on the biological impact of fresh milk, both short- and long-term, as well as defining and understanding healthcare economics when using fresh milk.

- Abstract
Background: When mother`s own milk (MOM) is unavailable or insufficient, donor milk (DM) from a human milk bank serves as an alternative feeding option. Our study sought to investigate and compare the outcomes and complications of very low birth weight (VLBW) preterm infants who receive MOM versus DM., Methods: In this retrospective cohort study conducted between 2018 and 2022, we compared 70 VLBW preterm infants exclusively fed with DM to 70 randomly selected counterparts fed with MOM. Both groups began enteral feeding within 72 hours of birth. Various clinical outcomes were investigated during a three-month follow-up. The clinical outcomes were compared via independent t-tests, Mann-Whitney U, and Fisher`s exact test., Results: The mean gestational age of the infants who were included was 29.6 ± 1.6 weeks, 84 (60%) were males, and the average birth weight was 1217 ± 151 grams. Both groups had similar baseline characteristics. The results of the study demonstrated no statistically significant differences between the groups in terms of hospital length of stay (37±16.3 days in MOM vs 40.3±16.9 days in DM group, P= 0.17), growth rate (13±4 gram/day in MOM vs 13±4 gram/day in DM group, P=0.51), growth velocity (9.8±3.0g/kg/d in MOM vs 9.5±3.2 g/kg/d in DM group), infants with in-hospital vomiting (51 cases in MOM vs 59 cases in DM group, P=0.15),vomiting frequency (1.3±1.1 times in MOM vs 1.5±1.0 times in DM group), incidence of retinopathy of prematurity (ROP) (4 cases in MOM vs 5 cases in DM group, P > 0.999) and incidence of bronchopulmonary dysplasia (BPD) (7 cases in MOM vs 6 cases in DM group, P > 0.999)., Conclusion: Our study findings indicate that the utilization of DM didn`t have a substantial negative impact on infants` outcomes nor any complications in comparison with MOM.

- Abstract
Purpose: Maternal concerns for health and growth in prematurely born infants affect the breastfeeding duration., Method: This prospective observational study evaluated whether maternal concerns regarding insufficient milk supply were supported by inadequate nutrients in human milk or low infant growth. The study followed mothers of 211 premature born infants for 6 months after delivery., Results: Of the 211 infants, 156 were not exclusively breastfed for the recommended 6 months after delivery. For 79 of these 156 infants, termination was due to maternal concerns regarding insufficient milk supply. There was no difference in human milk nutrients or infant growth when comparing infants who were exclusively breastfed with those who were not., Conclusion: Maternal concern regarding insufficient milk supply was the primary explanation for termination of exclusive breastfeeding after premature delivery. Concerns regarding insufficient milk supply were not found associated with inadequate nutrients in the human milk, nor with low infant growth., Implications: Breastfeeding support should remain in focus in this population., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Background: Lack of mother's own milk (MOM) at discharge from the neonatal intensive care unit (NICU) is a global problem and is often attributable to inadequate MOM volume. Evidence suggests that the origins of this problem are during the first 14 days postpartum, a time period that includes secretory activation (SA; lactogenesis II, milk coming in ). Objectives: To describe and summarize evidence regarding use of MOM biomarkers (MBMs) as a measure of SA in pump-dependent mothers of preterm infants in the NICU and to identify knowledge gaps requiring further investigation. Methods: An integrative review was conducted using Whittemore and Knafl methodology incorporating the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. A search using electronic databases MEDLINE (through PubMed) and CINAHL (Cumulative Index to Nursing and Allied Health Literature) and reference lists of included articles was conducted. Results: Of the 40 articles retrieved, 6 met the criteria for inclusion. Results revealed the following five findings: (1) Achievement of SA defined by MBMs is delayed and/or impaired in mothers of preterm infants. (2) MBMs are associated with pumped MOM volume. (3) Achievement of SA defined by MBMs is associated with pumping frequency. (4) Delayed and/or impaired achievement of SA defined by MBMs may be exacerbated by maternal comorbidities. (5) There is a lack of consensus as to which MBM(s) and analysis techniques should be used in research and practice. Conclusions: MBMs hold tremendous potential to document and monitor achievement of SA in mothers of preterm infants, with multiple implications for research and clinical practice.

Objective: Uncertainty exists regarding optimal supplemental diet for very preterm infants if the mother's own milk (MM) is insufficient. We evaluated feasibility for a randomised controlled trial (RCT) powered to detect important differences in health outcomes., Methods: In this open, parallel, feasibility trial, we randomised infants 25+0-31+6 weeks of gestation by opt-out consent to one of three diets: unfortified human milk (UHM) (unfortified MM and/or unfortified pasteurised human donor milk (DM) supplement), fortified human milk (FHM) (fortified MM and/or fortified DM supplement), and unfortified MM and/or preterm formula (PTF) supplement from birth to 35+0 weeks post menstrual age. Feasibility outcomes included opt-outs, adherence rates, and slow growth safety criteria. We also obtained anthropometry, and magnetic resonance imaging body composition data at term and term plus 6 weeks (opt-in consent)., Results: Of 35 infants randomised to UHM, 34 to FHM, and 34 to PTF groups, 21, 19, and 24 infants completed imaging at term, respectively. Study entry opt-out rate was 38%; 6% of parents subsequently withdrew from feeding intervention. Two infants met predefined slow weight gain thresholds. There were no significant between-group differences in term total adipose tissue volume (mean [SD]: UHM: 0.870 L [0.35 L]; FHM: 0.889 L [0.31 L]; PTF: 0.809 L [0.25 L], p = 0.66), nor in any other body composition measure or anthropometry at either timepoint., Conclusions: Randomisation to UHM, FHM, and PTF diets by opt-out consent was acceptable to parents and clinical teams, associated with safe growth profiles and no significant differences in body composition. Our data provide justification to proceed to a larger RCT., (© 2023 The Author(s). Published by S. Karger AG, Basel.)

- Abstract
Background: Breast milk is essential for premature infants. It contains a variety of functional and protective nutrients that help to create a suitable microenvironment for intestinal development and maturation. This prospective and observational study was planned to examine the effects of feeding premature infants with fresh or frozen breastmilk on their gut microbiota., Materials and Methods: The study was carried out with a total of 40 infants, with a gestational age of 28-32
6 weeks, fed fresh ( n = 20) or frozen ( n = 20) breastmilk. Stool samples were stored at -80°C until analysis. Infants were included in groups based on the feed type, which accounted for more than 70% of their 10-day feeding. The Mann-Whitney U, Chi-square, and t-tests were used to evaluate the demographic data. Stool samples were analyzed by sequencing the V3--V4 region of the 16S rRNA gene from the extracted DNA for microbiota analysis., Results: Streptococcus and Enterobacteriales, the majority of which are considered human pathogens, in infants receiving frozen breastmilk ( Streptococcus 69%, Enterobacteriales 79%) was higher than that in infants receiving fresh breastmilk ( Streptococcus 16%, Enterobacteriales 49%). Further, the Lactobacillus and Bifidobacterium species were more abundant in infants who received fresh breastmilk ( Lactobacillus 17%, Bifidobacterium 12%) than in infants who received frozen breastmilk ( Lactobacillus 3%, Bifidobacterium 1%)., Conclusion: Thus, compared to frozen breast milk, fresh breastmilk has an effect on the diversity of preterm infants' gut microbiota., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.- Published

- Abstract
Background & Aims: A balanced supply of arachidonic acid (ARA) and docosahexaenoic acid (DHA) may be crucial for quality of growth in preterm infants. This secondary analysis of a randomized controlled trial aimed to determine the effect of enhanced ARA and DHA supplementation on growth and body composition in infants born before 29 weeks of gestation. Furthermore, we aimed to study associations between human milk feeding, growth patterns and body composition., Methods: The ImNuT-trial randomized 121 infants to receive a daily supplement with medium chain triglycerides (control) or 100 mg/kg ARA and 50 mg/kg DHA (ARA:DHA group) from the second day of life until 36 weeks postmenstrual age. Growth and body composition were evaluated up to 3 months corrected age., Results: The ARA:DHA group showed better linear growth from birth to term equivalent age compared to the control group; mean difference in z score change from birth for length was 0.74 ([95% CI, 0.17-1.3]; p = 0.010). There were no differences in growth and body composition outcomes at 3 months corrected age between the groups. An increase in z score for weight after 36 weeks postmenstrual age and breastfeeding at 3 months corrected age were the strongest positive predictors of fat mass% at 3 months corrected age (both, p < 0.001)., Conclusion: Early enhanced supplementation of ARA and DHA may be beneficial with respect to somatic growth in very preterm infants., Clinical Trial Registration: The trial has been registered on www., Clinicaltrials: gov, ID: NCT03555019., Competing Interests: Conflict of interest The authors have no conflicts of interest to disclose., (Copyright © 2023 The Authors.

- 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., (© 2023. The Author(s).)

- Abstract
Human milk feeding can support premature infants to thrive. Yet those with premature infants can be challenged in human milk production. Considering this, and the use of potentially harmful human milk enhancers, the present study was conducted with the aim of determining the effect of orally consumed Lactuca sativa (L. sativa) syrup (lettuce extract) on human milk volume and subsequent weight gain in the preterm infant. Extracts from lettuce and other plants such as silymarin are already evidenced to be safe for use during lactation and have other therapeutic effects in humans. Yet this is the first study of its kind. This parallel randomized clinical trial included lactating participants with their preterm infants who were born at < 32 weeks' gestation and admitted to an intensive care unit. Convenience sampling was used to recruit participants. Eligible participants were allocated to groups randomly: intervention (n = 47), placebo (n = 46), and control (n = 47). The intervention group received one tablespoon of Lactuca sativa (L. sativa) syrup, and the placebo group received one tablespoon of placebo syrup 3 times a day for 1 week. Those in the control group did not receive any herbal or chemical milk-enhancing compounds. Routine care was provided to all three groups. Participants recorded their milk volume for 7 days in a daily information recorder form. Infant weight was measured prior to the intervention, and on the third, fifth and seventh days of the intervention period. There was a statistically significant difference observed in the adjusted mean volume of milk on the fourth and fifth days between the intervention, placebo, and control groups (P < 0.05). The adjusted mean milk volume of those in the intervention group on the first day was significantly higher than those in the control group and those in the placebo group. On the second day, the adjusted mean milk volume of those in the intervention group was higher than in those from the control group; and on the fourth day it was higher than in those from both the control and placebo groups; on the fifth day it was higher than in those in the placebo group; on the sixth day it was higher than in those in the control group and on the seventh day it was higher than in those in the control group (P < 0.05). There was no statistically significant difference in terms of the mean changes (with or without adjustment) in the weight of preterm infants between any of the groups. Lactuca sativa (L. sativa) syrup increases the volume of human milk production and no specific side effects have been reported in its use. Therefore, Lactuca sativa syrup can be recommended for use as one of the compounds that increase human milk volume., (© 2023. The Author(s).)

- Abstract
Background: Mother's breastmilk is the gold standard for feeding preterm infants. Preterm delivery may be precipitated by inflammatory maternal states, but little is known about milk cytokine profiles and how they correlate with markers of infant gut inflammation (i.e., stool calprotectin) in this vulnerable population., Research Aim: To assess cytokines and inflammatory markers in milk from parents of very preterm infants over time as well as correlations between milk and infant's stool calprotectin., Method: This is a secondary analysis of milk samples collected during OptiMoM, a triple-blind randomized clinical trial of infants born < 1250 g (NCT02137473). Longitudinally collected samples were analyzed for cytokines, choline, and inflammatory markers (C-reactive protein [CRP], IFN-γ, IL-10, IL-1β, IL-1ra, IL-6, IL-8, TNF-α). Infant stools were collected for longitudinal calprotectin analysis. Generalized estimating equations quantified longitudinal profiles of milk markers and stool calprotectin, their associations, and the correlation between free choline and C-reactive protein over follow-up., Result: Participants included 92 parents and infants (median weeks of gestation 27.3, median birth weight 845 g, and prevalence of male infants 45%). In all, 212 milk samples and 94 corresponding stool calprotectin levels were collected 1-11 weeks postpartum. C-reactive protein was present in much higher concentrations than other markers, and was highest in Week 1 postpartum. It decreased over time. IL-8 and free choline also changed over time while other markers did not. There was no correlation between any milk markers and stool calprotectin., Conclusion: Milk from mothers of very preterm infants has detectable inflammatory markers, some of which change over time. Research is needed to determine if infant outcomes are associated with these markers., Competing Interests: Disclosures and Conflicts of InterestThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- 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., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Aim: We aimed to gain insights into current nutritional management practices of late preterm infants (34-36 weeks gestational age) in Nigeria., Methods: Purposive sampling was employed to recruit 19 healthcare professionals (neonatologists, paediatricians, general practitioners and nurses) involved in the care and nutritional management of late preterm infants in Lagos and Ogun states, Nigeria. Data were collected using interviews, either individually or in small focus groups, between 15 August and 6 September 2022. Thematic analysis of interview transcripts was carried out to interpret the data., Results: Ten distinct themes emerged across the research questions and objectives. For growth monitoring, 11, 6, 1 and 1 of our participants preferred to use the 2006 WHO growth standards, Fenton preterm growth chart, Ballard score and Intergrowth-21, respectively. Regarding the growth velocity of late preterm infants, most healthcare professionals aimed for 15 g/kg BW/day or more during hospitalisation. Breastmilk was unanimously the primary feeding option for late preterm infants. Most healthcare professionals preferred to use international guidelines over local guidelines., Conclusion: Our study shows that there is a wide divergence in the nutritional guidelines used in managing late preterm infants in Nigeria. Regarding growth monitoring, healthcare professionals tended to aim for a growth velocity higher than necessary for late preterm infants, which may be disadvantageous for their long-term health., (© 2023 The Authors.

- Abstract
Background: Human milk is the preferred diet for very low birth weight (VLBW, <1500 g) infants. When mother's own milk is unable to meet the needs of VLBW infants, donor human milk (DHM) is the preferred alternative. Unfortunately, the composition of DHM remains elusive and no comparative studies between preterm human milk and DHM have been performed previously., Objectives: We aimed to analyze the nutrient content of commercial pooled DHM and compare nutrient content in DHM with that of early and mature preterm human milk., Methods: We analyzed nutrient content in 15 DHM samples provided from 7 commercial milk banks including calories, carbohydrate, fat, protein, sodium, chloride, potassium, zinc, calcium, phosphorus, magnesium, and vitamin D and compared each nutrient to early (7 d of life) and mature (28 d of life) preterm human milk samples (n = 28-36 per nutrient, gestational age = 28 ± 3 wk). Protein-to-energy ratio and carbohydrate-to-nonprotein energy ratio were calculated for each sample and compared., Results: Mean values for all macro- and micronutrients in DHM are reported. In comparison to early or mature preterm human milk, DHM had significantly lower protein, sodium, chloride, potassium, and zinc content. Calorie, carbohydrate, calcium, phosphorus, magnesium, and vitamin D content did not differ statistically between DHM and early or mature preterm human milk. Fat content was modestly lower in early but not mature human milk when compared with DHM., Conclusions: We provide mean values for several macro- and micronutrients for DHM and identify key differences between DHM and preterm human milk, which may be considered when designing human milk-based feeding plans.

- Abstract
Background: Human milk-based fortifiers (HMBF) are more costly than bovine milk-based fortifiers (BMBF); but, the efficacy of human or bovine fortification for infants born <1250 g has yet to be fully elucidated. Our objective was to determine the effect of fortifier source on tertiary neonatal costs., Methods: Costs associated with tertiary neonatal care, including direct and indirect hospital expenditures, feed-related costs and physician billing were analysed retrospectively for participants of OptiMoM (NCT02137473), a blinded RCT comparing fortifier type for babies born <1250 g. A generalized linear model of cost according to fortifier type was created., Results: Mean [95% confidence interval] daily costs per patient, adjusted for birth gestation and weight, was significantly greater in the human than the BMBF group ($3,452 [$3,186 - $3,740] Canadian dollars (CAD) versus $2,451 [$2,257 - $2,662] CAD) respectively, p < 0.0001)., Conclusion: HMBF usage entails additional costs on NICU stay that should be considered with implementation., (© 2023.

- Abstract
Background: Longitudinally conserved microbe-microbe interactions may provide insights to understand the complex dynamic system of early-life gut microbiota among preterm infants., Objectives: We aimed to profile the covarying network of gut microbiota among preterm infants and investigate its potential influence on host growth (2-5 y)., Methods: We collected time-series stool samples (n = 717 from children and n = 116 from mothers) among 51 preterm and 51 full-term infants from birth up to 5 y of age and among 53 mothers. The included infants underwent time-series measurements of early-life gut microbiota (0-5 y) and growth (2-5 y) from June 2014 to April 2017. The covarying taxa that exhibited consistent covariation from day 1 to year 5 were defined as conserved features in the development of gut microbiota. Childrens' height-for-age z score (HAZ) and weight-for-age z score were calculated according to World Health Organization Child Growth Standards., Results: We observed distinct dynamic patterns of both microbial alpha and beta diversity comparing preterm infants with full-term controls during the very early stage (<3 mo). Moreover, we identified a covarying network containing 10 taxa as a conserved gut microbial feature of these preterm infants from birth to 5 y old. This covarying network was distinctive between preterm and full-term infants before 3 mo of age (P < 0.001) and tended to be similar as the infants grew up. Several covarying taxa of the network during early life (<3 mo) were associated with childhood growth (2-5 y) (eg, Clostridium_sensu_stricto_1 with HAZ, β = -0.32, q < 0.01), and the human milk feeding duration was a main modulating factor., Conclusions: Preterm born children possess conserved and distinct covarying microbiota during very early life, which may have a profound influence on their growth later in life.

- Abstract
Background: Human milk (HM) is a proven optimal food for preterm infants. However, there is uncertainty regarding the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants. Therefore, we conducted a systematic review of studies examining the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants. Methods: We conducted a literature search in the Web of Science, PubMed, and Scopus databases. The methodological quality of the included articles and the certainty of evidence were assessed according to the Newcastle-Ottawa Scale and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool, respectively. Results: Twelve studies were included in the review. Among the clinical findings, the effect of different proportions of HM of the total enteral feeding on health outcomes in preterm infants was divided into six primary outcomes: physical growth, length of stay, morbidity of any disease, all-cause mortality, feeding-related outcomes, and other health outcomes. The studies presented a high risk of bias for most of the domains. The certainty of the evidence was considered low or very low. Conclusions: The findings reiterated that greater proportions of HM positively affect the health outcomes of preterm infants. Overall, when the HM accounts for at least 20% of the total enteral intake, it has an effect on health outcomes in preterm infants. If the proportion of HM reaches 50%, the incidence and severity of necrotizing enterocolitis, as well as the time to reach enteral feeds, will be reduced. Increasing the proportion of HM in enteral feeding should be considered a priority in the feeding strategy for preterm infants in clinical practice.

- Abstract
Immunoglobulin A (IgA) is secreted into breast milk and is critical for both protecting against enteric pathogens and shaping the infant intestinal microbiota. The efficacy of breast milk-derived maternal IgA (BrmIgA) is dependent upon its specificity; however, heterogeneity in BrmIgA binding ability to the infant microbiota is not known. Using a flow cytometric array, we analyzed the reactivity of BrmIgA against bacteria common to the infant microbiota and discovered substantial heterogeneity between all donors, independent of preterm or term delivery. Surprisingly, we also observed intradonor variability in the BrmIgA response to closely related bacterial isolates. Conversely, longitudinal analysis showed that the antibacterial BrmIgA reactivity was relatively stable through time, even between sequential infants, indicating that mammary gland IgA responses are durable. Together, our study demonstrates that the antibacterial BrmIgA reactivity displays interindividual heterogeneity but intraindividual stability. These findings have important implications for how breast milk shapes the development of the preterm infant microbiota and protects against necrotizing enterocolitis., (© 2023 Johnson-Hence et al.)

- Abstract
Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. ROP occurs in infants who are born very preterm. In ROP, retinal blood vessel development, which is prematurely arrested in preterm infants, is altered by perinatal exposures like oxygen and inflammation. Optimizing nutritional practices for preterm infants may mitigate the risk of ROP. In this article, we review the evidence that postnatal growth, hyperglycemia, polyunsaturated fatty acids, and breast milk provision may affect ROP risk. We also outline the current management strategies for ROP and describe the vision outcomes of children affected by ROP. [ Pediatr Ann . 2023;52(8):e303-e308.] .

- Abstract
Background: In 2020, a multidose human-milk fortifier (MDHMF) was designed to improve the process of human-milk (HM) fortification. The bottle of MDHMF (5.5 oz, 163 ml) allows aseptic removal of HMF in a precise measure. This survey aimed to examine the experience of nutrition care team (NCT) members who used the MDHMF in a hospital setting., Methods: A survey link (Qualtrics XM) was sent to NCT leaders (N = 108) at hospitals who participated in an evaluation of the MDHMF from June 1, 2020, through April 30, 2021. The NCT leaders sent the survey to members at their prospective hospitals (n = 344). The investigators did not know the identities of the recipients of the survey and collected no identifying information on respondents. Respondents were asked to evaluate their experience with the MDHMF compared with their previous practice., Results: The majority of respondents (n = 63, 72%) reported that the MDHMF improved their HM preparation practices and was better than their previous practice for reducing the time to prepare (n = 33, 71.7%), ensuring the accuracy of fortified HM (n = 32, 69.6%), ensuring aseptic preparation (n = 24, 52.2%), reducing HM waste (n = 27, 58.7%), and being easy to use (n = 30, 65.2%). Those responsible for evaluating nutrition status answered that the MDHMF was the same for feeding tolerance (n = 41, 58.6%), weight gain (n = 47, 67.1%), head growth (n = 56, 81.2%), and length growth (n = 53, 76.8%)., Conclusion: US neonatal intensive care unit NCT members perceived that the MDHMF resulted in improved HM preparation practices while maintaining growth and tolerance., (© 2022 Reckitt Mead Johnson Nutrition.

Objective: To examine associations between early exposure to mother's own milk (MOM) and neurodevelopmental outcomes among preterm infants, and to compare these associations between singletons and twins., Study Design: Retrospective cohort study that included low-risk infants born at <32 weeks gestational age. Nutrition was documented over a 3-day period at mean ages of 14 and 28 days of life; an average of the 3 days was calculated. The Griffiths Mental Development Scales (GMDS) were administered at 12 months corrected age., Results: Preterm infants (n = 131) with median gestational age of 30.6 weeks were included; 56 (42.7%) were singletons. On days 14 and 28 of life, 80.9% and 77.1% were exposed to MOM, respectively. Exposure rate was comparable, but MOM intake (mL/kg/day) was higher among singletons than among twins (P < .05). At both time points, MOM-exposed infants scored higher on personal-social, hearing-language, and total GMDS assessments than nonexposed infants. These differences were significant for the entire cohort and for twins (P < .05). MOM intake correlated with total GMDS score for both singletons and twins. Any exposure to MOM was associated with additional 6-7 points on total GMDS score or 2-3 additional points for every 50 mL/kg/day of MOM., Conclusions: The study supports the positive association between early MOM exposure among low-risk preterm infants and neurodevelopmental outcomes at 12 months corrected age. The differential effects of MOM exposure on singletons vs twins need further exploration., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare that are relevant to the content of this article., (Copyright © 2023 Elsevier Inc.

- Abstract
Aim: We compared milk volumes, skin-to-skin contact and breastfeeding by the mothers of very preterm twins and singleton infants born at 28-32 weeks of gestation., Methods: This Norwegian longitudinal prospective comparative study was carried out in two neonatal intensive care units: one with single family rooms and one open bay unit. It comprised 49 singleton infants, 28 twins and their mothers. The mothers' milk volume and direct breastfeeding were recorded from birth until 4 months' of corrected age. They also answered the breastfeeding self-efficacy scale and skin-to-skin contact was recorded., Results: The mothers of preterm twins produced doubled the volume of expressed milk at day 14, compared to the mothers of singletons (mean 816 ± 430 mL vs. 482 ± 372 mL, p < 0.05) and this difference was still sustained at 34 + 0 weeks/days (p < 0.02). Mothers of twins had their first breastfeeding attempt later than mothers of singletons (median of 133 h compared to 56 (p < 0.002). Preterm twins received less daily skin-to-skin contact (mean 157 ± 66 min each vs. 244 ± 109) (p < 0.001). There were no differences in receiving mother's own milk, exclusively direct breastfeeding or perceived breastfeeding self-efficacy., Conclusion: Breastfeeding was initiated as successfully in preterm twins as singletons as the mothers' milk production doubled., (© 2023 Foundation Acta Paediatrica.
