J Pediatr Gastroenterol Nutr 2024; 78:471-487. [PMID: 38314925 DOI: 10.1002/jpn3.12085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 02/07/2024]
Abstract
Various studies have shown that oropharyngeal colostrum application (OPCA) is beneficial to preterm neonates. We performed a systematic review and meta-analysis to assess whether OPCA reduces the incidence of culture-proven neonatal sepsis in preterm neonates. Randomized controlled trials comparing OPCA with placebo or standard care in preterm neonates were included. Medline, Embase, Web of Science, Cumulated Index to Nursing and Allied Health Literature, Scopus, and CENTRAL were searched for studies published up to June 15, 2023. We used the Cochrane Risk of Bias tool, version 2, for risk of bias assessment, the random-effects model (RevMan 5.4) for meta-analysis, and Gradepro software for assessing the certainty of evidence. Twenty-one studies involving 2393 participants were included in this meta-analysis. Four studies had a low risk of bias, whereas seven had a high risk. Oropharyngeal colostrum significantly reduced the incidence of culture-proven sepsis (18 studies, 1990 neonates, risk ratio [RR]: 0.78, 95% confidence interval [95% CI]: 0.65, 0.94), mortality (18 studies, 2117 neonates, RR: 0.73, 95% CI: 0.59, 0.90), necrotizing enterocolitis (NEC) (17 studies, 1692 neonates, RR: 0.59, 95% CI: 0.43, 0.82), feeding intolerance episodes (four studies, 445 neonates, RR: 0.59, 95% CI: 0.38, 0.92), and the time to full enteral feeding (19 studies, 2142 neonates, mean difference: -2 to 21 days, 95% CI: -3.44, -0.99 days). There was no reduction in intraventricular hemorrhage, retinopathy of prematurity, bronchopulmonary dysplasia, ventilator-associated pneumonia, neurodevelopmental abnormalities, hospital stay duration, time to full oral feeding, weight at discharge, pneumonia, and duration of antibiotic therapy. The certainty of the evidence was high for the outcomes of culture-positive sepsis and mortality, moderate for NEC, low for time to full enteral feeding, and very low for feeding intolerance. OPCA reduces culture-positive sepsis and mortality (high certainty), NEC (moderate certainty), and time to full enteral feeding (low certainty) in preterm neonates. However, scarcity of data from extremely premature infants limits the generalizability of these results to this population.

Oropharyngeal administration of colostrum targeting gut microbiota and metabolites in very preterm infants: protocol for a multicenter randomized controlled trial. BMC Pediatr 2023; 23:508. [PMID: 37845612 PMCID: PMC10577906 DOI: 10.1186/s12887-023-04346-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 10/03/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Oropharyngeal administration of colostrum (OAC) has an immune-stimulating effect on oropharyngeal-associated lymphoid tissue, and can promote the maturation of the gastrointestinal tract. However, how OAC promotes intestinal maturation in preterm infants by altering gut microbiota remains unclear. We aim to assess changes in gut microbiota and metabolites after OAC in very preterm infants. METHODS A multicenter, double-blind, randomized controlled trial will be conducted in three large neonatal intensive care units in Shenzhen, China, with preterm infants with gestational age less than 32 weeks at birth and birth weight less than 1500 g. It is estimated that 320 preterm infants will be enrolled in this study within one year. The intervention group will receive oropharyngeal administration of 0.2 ml colostrum every 3 h, starting between the first 48 to 72 h and continued for 5 consecutive days. Following a similar administration scheme, the control group will receive oropharyngeal administration of sterile water. Stool samples will be collected at the first defecation, as well as on the 7th, 14th, 21st and 28th days after birth for analysis of effect of OAC on gut microbiota and metabolites through 16sRNA gene sequencing and liquid chromatography-mass spectrometry. DISCUSSION This proposal advocates for the promotion of OAC as a safe and relatively beneficial protocol in neonatal intensive care units, which may contribute to the establishment of a dominant intestinal flora. Findings of this study may help improve the health outcomes of preterm infants by establishment of targeted gut microbiota in future studies. TRIAL REGISTRATION NCT05481866 (registered July 30, 2022 on ClinicalTrials.gov).

Abstract
CONTEXT Many preterm neonates often cannot be fed enterally and hence do not receive the benefits of colostrum. Oropharyngeal application of colostrum is a novel way of harnessing the immunological benefits of colostrum. Randomized controlled trials (RCTs) investigating the efficacy of this approach have shown variable results. OBJECTIVE The aim of this systematic review was to synthesize available data on the effect of oropharyngeal application of colostrum or mother's own milk (CMOM) in preterm infants. DATA SOURCES Six electronic databases (MEDLINE, Embase, CINAHL, Scopus, Web of Science, and Cochrane Library) were searched until January 13, 2022. Only RCTs comparing oral application of CMOM with placebo/routine care in preterm infants were eligible. Studies enrolling term neonates or administering enteral feeds were excluded. DATA EXTRACTION Two investigators independently extracted data using a structured proforma. DATA ANALYSIS The Cochrane Risk of Bias 2 tool was used to assess bias. Random-effects meta-analysis was undertaken using RevMan 5.4 software. From 2787 records identified, 17 RCTs enrolling 4106 preterm infants were included. There was no significant difference between groups in incidence of necrotizing enterocolitis (NEC) stage 2 or higher (RR = 0.65; 95%CI, 0.36-1.20; 1089 participants in 12 trials). Application of CMOM significantly reduced the incidence of sepsis (RR = 0.72; 95%CI, 0.56-0.92; 1511 participants in 15 studies) and any stage of NEC (RR = 0.58; 95%CI, 0.37-0.92; 1616 participants in 16 trials). The CMOM group achieved full enteral feeds 1.75 days sooner (95%CI, 0.3-3.2 days; 1580 participants in 14 studies) and had higher weight at discharge (MD = 43.9 g; 95%CI, 3-85 g; 569 participants in 3 studies). There were no statistically significant differences in other outcomes. CONCLUSIONS Evidence with low to very low certainty suggests CMOM has a beneficial effect on NEC (any stage), sepsis, and time to full enteral feeds. Given its low cost and minimal risk of harm, routine CMOM use may be considered in preterm neonates. PROSPERO REGISTRATION NUMBER CRD42021262763.

Abstract
BACKGROUND Several studies have focused on the clinical outcomes of oral care using colostrum for a limited time (2-5 days) in very-low-birthweight (VLBW) infants. However, the effect of long-term mother's own milk (MOM) on the clinical outcomes and oral microbiota of VLBW infants remains unknown. METHODS In this randomized controlled trial, VLBW neonates were randomly assigned to oral care by MOM or sterile water (SW) groups until they started oral feeding. The primary outcome was oral microbiota composition including alpha and beta diversity, relative abundance, and linear discriminant analysis effect size (LEfSe). The secondary outcomes were various morbidities and mortality. RESULTS The baseline characteristics of the two groups did not differ (63 neonates, MOM group, n = 30, oral care 22 days; SW group, n = 33, oral care 27 days). There was no significant difference in alpha and beta diversities between the groups before and after the intervention. The MOM group had a significantly lower rate of clinical sepsis than the SW group (47% vs. 76%, risk ratio = 0.62, 95% CI: 0.40-0.97). The relative abundance of Bifidobacterium bifidum and Faecalibacterium were maintained after MOM care, especially in neonates without clinical sepsis, but decreased after SW care. LEfSe showed that neonates in the MOM and SW groups with clinical sepsis had the highest abundance of Pseudomonas and Gammaproteobacteria, respectively, compared with neonates without sepsis. CONCLUSIONS A longer duration of oral care using MOM in VLBW infants sustains healthy bacteria and decreases the risk of clinical sepsis.

Int J Nurs Stud 2023; 144:104527. [PMID: 37295286 DOI: 10.1016/j.ijnurstu.2023.104527] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 05/09/2023] [Accepted: 05/12/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Preterm complications are now the second leading cause of death in children under five years of age. Colostrum is essential to prevent infection and promote maturation in preterm infants. Guidelines recommend that preterm infants be fed colostrum by the oral and pharyngeal routes as early as possible after birth to provide immune protection; however, due to disease and an uncoordinated sucking and swallowing function, it is challenging to provide colostrum through the oropharyngeal route, which limits the immune protection it provides. OBJECTIVE To update the existing meta-analysis, evaluate the effect of oropharyngeal colostrum administration on related outcomes in preterm infants and explore the optimal frequency and duration of oropharyngeal colostrum administration through subgroup analysis. METHODS The Cochrane Library, PubMed, Web of Science, ScienceDirect, and Ovid databases were searched for randomized control trials (RCTs) of oropharyngeal colostrum administration for preterm infants. Two researchers screened the literature strictly according to the inclusion and exclusion criteria and evaluated the quality. Primary data and data from the included literature were extracted. Finally, the data were statistically analyzed by the Review Manager 5.3 software. RESULTS A total of 1736 preterm infants were included in 16 RCTs. The meta-analysis showed that the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and death was lower, the time to full enteral feeding was shorter, and the day of recovery to birth weight was earlier in the intervention group (oropharyngeal colostrum administration group) than in the control group, and this difference was statistically significant. Subgroup analysis: Frequency of oropharyngeal colostrum administration: The incidence of necrotizing enterocolitis and late-onset sepsis in the once every 4 h group was lower than that in the control group, and the time to complete enteral feeding was shorter. Duration of oropharyngeal colostrum administration: In the 1-3 days group and 4-7 days group, the time to full enteral feeding in the intervention group was shorter. In the 8-10 days group, the incidence of necrotizing enterocolitis and late-onset sepsis was lower in the intervention group. CONCLUSIONS Oropharyngeal colostrum administration can reduce the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance and mortality, shorten the time to full enteral feeding, and lead to a faster recovery to birth weight in preterm infants. The appropriate oropharyngeal colostrum administration frequency may be 4 h, and the optimal duration may be 8-10 days. Therefore, it is recommended that clinical medical staff implement oropharyngeal colostrum administration for premature infants based on existing evidence. TWEETABLE ABSTRACT Oropharyngeal colostrum administration can reduce the incidence of complications in preterm infants and shorten the time to full enteral feeding.

Abstract
Research on human milk has increased dramatically in recent years. The purpose of this review is to describe the literature on the health benefits of human milk for hospitalized, vulnerable neonates. PubMed, CINAHL, and Embase were searched for research articles reporting the health outcomes of hospitalized neonates who were exposed to human milk. Human milk, particularly a mother's own milk, has the potential to reduce the risk of death and the risk and severity of necrotizing enterocolitis, infection, retinopathy of prematurity, bronchopulmonary dysplasia, intraventricular hemorrhage, kidney disease, and liver disease. Dose and timing of human milk is important, with more human milk and earlier introduction having a greater impact on health. When a mother's own milk is not available, donor human milk provides benefits over infant formula.

Abstract
OBJECTIVE To determine if oropharyngeal therapy with mother's own milk (OPT-MOM) reduces late-onset sepsis (L-OS; primary outcome), NEC, death, length of stay, time to full enteral nutrition (FEN) and full oral feeds in preterm infants (BW < 1250 g). DESIGN Infants (N = 220) were randomized to Group A (milk) or B (placebo) and received 0.2 mL every 2 h for 48 h, then every 3 h until 32 weeks CGA. RESULTS There were no significant differences in L-OS, NEC or death. Group A trended towards an 8-day reduction in stay, 8-day reduction in time to FEN and a 6-day reduction in time to full oral feeds, compared to B. While clinically relevant, due to large variability in outcomes and lack of power, p values were > 0.05. CONCLUSION OPT-MOM did not reduce L-OS, NEC or death. Group A trended towards a reduced stay and better nutritional outcomes, but results were not statistically significant. CLINICALTRIALS GOV: NCT02116699.

Abstract
Background Necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) are the major contributors to mortality and morbidity in preterm infants. This updated meta-analysis was aimed to assess the effects of mother's milk on the incidence of NEC, LOS, and other clinical outcomes in preterm infants. Methods PubMed, Embase, and the Cochrane library were searched for papers published up to October 2022. Results A total of 13 RCTs with 1330 infants were included in the final analysis. Significant difference in NEC (stage 2 or 3) was found between the intervention group and the control group (RR = 0.508, 95% CI: 0.314-0.822, and P=0.008). The incidence of proven LOS (RR = 0.809, 95% CI: 0.610-1.071, and P=0.139) and death (RR = 0.800, 95% CI: 0.571-1.122, and P=0.196) was comparable between the two groups. Statistical differences in the incidence of proven or probable LOS (RR = 0.705, 95% CI: 0.577-0.862, and P=0.001) and length of hospitalization (WMD = -4.868, 95% CI: -6.608 to -3.128, and P < 0.001) between the intervention group and the control group were observed. Conclusions The results of this updated meta-analysis showed that compared to the placebo, mother's milk provides better effects in reducing the incidences of NEC, proven or probable LOS, and the length of stay, whereas no significant benefit of mother's milk was observed in reducing the incidence of proven LOS and death.

Abstract
Objective: Colostrum, the first form of human milk, is strongly encouraged for infants due to its benefits. During the early postpartum (PP) period, the secreted colostrum volume can be minimal, causing concerns among mothers about sufficient milk supply. Few studies have examined temporal changes in the colostrum. This study aimed to elucidate the trajectory of expressed colostrum volume in the first 48 hours after delivery. Materials and Methods: This was a cross-sectional observational study performed at Kagawa National Children's Hospital. One hundred five mothers who did not directly breastfeed in the first 48 hours after delivery were enrolled in the study. Well-trained midwives instructed the mothers on how to express human milk, and mothers started to express as soon as possible after delivery. Mothers were advised to express human milk every 3 hours, and the milk volume was measured. Results: Within 3 hours PP, 60% of mothers expressed milk, and the median frequency of expression was 14 (interquartile range, 11-16) times in the first 48 hours. At 0-3 and 3-6 hours PP, the volume of initially expressed milk was 0.4 (0.0-2.0) mL and 1.0 (0.0-6.0) mL, respectively. Subsequently, milk volume decreased. The volume remained low until 30 hours PP and increased dramatically; this phenomenon is termed secretory activation, which began later in primiparous women than in multiparous women. Conclusion: The decline in expressed milk volume during the early PP period caused concern among mothers. Therefore, mothers should be informed of the PP trajectory of human milk volume.
