Improving growth in preterm infants through nutrition: a practical overview. Front Nutr 2024; 11:1449022. [PMID: 39318385 PMCID: PMC11421391 DOI: 10.3389/fnut.2024.1449022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Accepted: 08/30/2024] [Indexed: 09/26/2024] Open
Abstract
The primary purpose of this practical overview is to provide a practical update on appropriate nutritional strategies to improve growth in preterm infants. Current recommendations for improving preterm growth concern both macronutrients and micronutrients, with tailored nutrition since the first days of life, particularly when fetal growth restriction has been reported. Human milk is undoubtedly the best nutrition for all newborns, but, in some populations, if not adequately fortified, it does not adequately support their growth. In all preterms, growth should be correctly monitored weekly to intercept a negative trend of growth and implement nutritional strategies to avoid growth restriction. Similarly, growth should be accurately supported and monitored after discharge to improve long-term health consequences.

Abstract
BACKGROUND When sufficient maternal milk is not available, donor human milk or formula are the alternative forms of enteral nutrition for very preterm or very low-birthweight (VLBW) infants. Donor human milk may retain the non-nutritive benefits of maternal milk and has been proposed as a strategy to reduce the risk of necrotising enterocolitis (NEC) and associated mortality and morbidity in very preterm or VLBW infants. OBJECTIVES To assess the effectiveness of donor human milk compared with formula for preventing NEC and associated morbidity and mortality in very preterm or VLBW infants when sufficient maternal milk is not available. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Maternity and Infant Care (MIC) database, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), from the earliest records to February 2024. We searched clinical trials registries and examined the reference lists of included studies. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing feeding with donor human milk versus formula in very preterm (< 32 weeks' gestation) or VLBW (< 1500 g) infants. DATA COLLECTION AND ANALYSIS Two review authors evaluated the risk of bias in the trials, extracted data, and synthesised effect estimates using risk ratio, risk difference, and mean difference, with associated 95% confidence intervals. The primary outcomes were NEC, late-onset invasive infection, and all-cause mortality before hospital discharge. The secondary outcomes were growth parameters and neurodevelopment. We used the GRADE approach to assess the certainty of the evidence for our primary outcomes. MAIN RESULTS Twelve trials with a total of 2296 infants fulfilled the inclusion criteria. Most trials were small (average sample size was 191 infants). All trials were performed in neonatal units in Europe or North America. Five trials were conducted more than 40 years ago; the remaining seven trials were conducted in the year 2000 or later. Some trials had methodological weaknesses, including concerns regarding masking of investigators and selective reporting. Meta-analysis showed that donor human milk reduces the risk of NEC (risk ratio (RR) 0.53, 95% confidence interval (CI) 0.37 to 0.76; I² = 4%; risk difference (RD) -0.03, 95% CI -0.05 to -0.01; 11 trials, 2261 infants; high certainty evidence). Donor human milk probably has little or no effect on late-onset invasive infection (RR 1.12, 0.95 to 1.31; I² = 27%; RD 0.03, 95% CI -0.01 to -0.07; 7 trials, 1611 infants; moderate certainty evidence) or all-cause mortality (RR 1.00, 95% CI 0.76 to 1.31; I² = 0%; RD -0.00, 95% CI -0.02 to 0.02; 9 trials, 2116 infants; moderate certainty evidence). AUTHORS' CONCLUSIONS The evidence shows that donor human milk reduces the risk of NEC by about half in very preterm or VLBW infants. There is probably little or no effect on late-onset invasive infection or all-cause mortality before hospital discharge.

Abstract
Neonates with absent-or-reversed umbilical artery end-diastolic flow (AREDF) are at an increased risk of feeding problems. In this retrospective study, authors evaluated the incidence of feed intolerance in 213 preterm neonates (January 2017-May 2022) with AREDF. The median (IQR) gestation and birth weight were 32 (30, 33) wk and 1120 (840, 1425) g, respectively. Of 213 neonates, 103 (48.4%; 95% CI 41.5%, 55.3%) neonates developed feed intolerance. Twelve of 213 neonates developed any stage necrotizing enterocolitis (NEC) (5.6%; 95% CI 2.9%, 9.6%) at a median age of 10 d. On multivariate regression, gestation was the only independent predictor of feed intolerance (OR 1.48; 95% CI 1.28, 1.70; for every 1 wk decrease below 36 wk). Almost 50% of preterm neonates with AREDF develop feed intolerance. Alternative feeding strategies warrant exploration to optimise nutrition in these neonates.

Abstract
Introduction: Human milk is the preferred source of enteral nutrition for very low birthweight (VLBW) infants, and it possibly decreases dependence on parenteral nutrition (PN) and reduces incidence of late-onset sepsis (LOS). No systematic review to date has specifically addressed the value of early versus late introduction of human milk diet (HMD) on duration of PN and incidence of LOS among VLBW infants. Objective: To review the evidence for an early versus late introduction of HMD on duration of PN and incidence of LOS in VLBW infants. Method: Preferred reporting items for systematic reviews and meta-analysis-guided search of EMBASE and PubMed/Medline databases was conducted for this systematic review using phrases addressing population, intervention, comparator, and outcome framework to identify articles published over the past two decades without language restrictions. Full-text articles (both observational and randomized) that studied an early versus late initiation of HMD were included. Mean difference (MD) and relative risk (RR) with 95% confidence intervals (CIs) were calculated for PN and LOS. Quality of evidence was analyzed using UK National Service Framework and the risk-of-bias was assessed using Robvis®. Results: One randomized controlled trial (RCT) and two observational studies (two English and one Chinese) recruited 474 VLBW infants (455 analyzed). Among an intrauterine growth-restricted cohort enrolled in the RCT (n = 72), early HMD resulted in statistically significant reduction in PN dependence. However, no statistically significant difference was found in LOS. Two observational studies found similar reductions in PN duration and LOS incidence among the early HMD cohort. One observational study reported significant PN reduction; however, the incidence of LOS did not reach statistical significance in either case. Conclusion: An early HMD may reduce the duration of PN for a growth-restricted VLBW cohort. Observational studies suggesting reduced PN and LOS from early HMD endorse the need for bioactivity-focused human milk research. Variations in feeding guidelines among VLBW infants have the potential to influence neonatal outcomes significantly.

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
OBJECTIVE Aim: To compare X-ray signs in different gestational and body weight groups of patients with NEC. PATIENTS AND METHODS Materials and Methods: We conducted a retrospective study, enrolling 52 preterm newborns with symptoms of NEC regardless of onset time, who underwent treatment at Neonatal Intensive Care Units in Municipal Non-commercial enterprise "City Children Hospital №2", Odesa. The patients were split into 3 clinical groups: very preterm newborns (VPN), moderately preterm newborns (MPN), and moderately preterm newborns with intrauterine growth restriction (MPN+IUGR). RESULTS Results: In the VPN group NEC was diagnosed at stage II (58,82±12,30) % and III (41,18±12,30) % by Bell MJ, р>0,05. In the group MPN+IUGR, NEC stage II (33,33±14,21) % and stage III (66,66 ±14,21) %, р>0,05, were equally observed. In the MPN group, NEC was diagnosed at stage I (41,67±10,28) % and II (58,33±10,28) %, р>0,05, without prevalence of any. Also only localized forms were observed. In VPN, we observed localized forms in most cases, while diffuse forms were diagnosed in (11,76±8,05) % cases, р<0,05. In the MPN+IUGR group, we found diffuse form of the NEC in half of the cases - (50,00±15,08) %. In the VPN and MPN+IUGR groups, NEC developed at 13,23±0,39 and 14,33±1,19 days, respectively. However, in MPN without IUGR, NEC developed at 17,75±0,55 days, significantly later than in the MPN+IUGR group, р<0,05. CONCLUSION Conclusions: We have described distinct features of NEC in MPN with IUGR. Compared to MPN without IUGR, NEC had more severe course and earlier manifestation in such neonates.

Abstract
Establishing full enteral nutrition in critically ill preterm infants with immature gastrointestinal function is challenging. In this article, we will summarize emerging clinical evidence from randomized clinical trials suggesting the feasibility and efficacy of feeding interventions targeting the early establishment of full enteral nutrition. We will also examine trial outcomes of higher volume feedings after the establishment of full enteral nutrition. Only data from randomized clinical trials will be discussed extensively. Future opportunities for clinical research will also be presented.

Abstract
OBJECTIVES In this systematic review and meta-analysis, we attempted to determine the most appropriate feed initiation and advancement practices in preterm neonates with antenatal Doppler abnormalities. METHODS We included randomized controlled trials comparing different feed initiation and advancement practices in neonates with antenatal Doppler abnormalities. The databases of PubMed, Embase, Cochrane, CINAHL, Scopus, and Google Scholar were searched on February 25, 2022. The risk of bias was assessed using the Risk of Bias tool, version 2. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. RevMan 5.4 was used for data analysis. RESULTS Of the 1499 unique records identified, 7 studies were eligible for inclusion (6 on feed initiation, 1 on feed advancement). Early enteral feeding did not increase NEC stage 2 or more [risk ratio (RR) 1.12, 95% confidence interval (CI) 0.71-1.78; 6 studies, 775 participants] and mortality (RR 0.83, 95% CI 0.47-1.48; 5 studies, 642 participants). A trend was noted towards an increase in feeding intolerance (RR 1.23, 95% CI 0.98-1.56; 5 studies, 715 participants). There was a significant reduction in age at full enteral feeds, duration of total parental nutrition, and rates of hospital-acquired infections. Rapid feed advancement decreased the age at full enteral feeds without affecting other outcomes. The overall certainty of the evidence was rated low. Heterogeneity was not significant. CONCLUSION There is low-certainty evidence that early feed initiation in preterm neonates with antenatal Doppler abnormalities does not increase rates of NEC and mortality. There is insufficient data on the speed of feed advancement.

Abstract
CONTEXT Early enteral feeding has been associated with adverse outcomes such as necrotizing enterocolitis in preterm and low birth weight infants. OBJECTIVES To assess effects of early enteral feeding initiation within the first days after birth compared to delayed initiation. DATA SOURCES Medline, Scopus, Web of Science, CINAHL from inception to June 30, 2021. STUDY SELECTION Randomized trials (RCTs) were included. Primary outcomes were mortality, morbidity, growth, neurodevelopment, feed intolerance, and duration of hospitalization. DATA EXTRACTION Data were extracted and pooled with random-effects models. RESULTS We included 14 randomized controlled trials with 1505 participants in our primary analysis comparing early (<72 hours) to delayed (≥72 hours) enteral feeding initiation. Early initiation likely decreased mortality at discharge and 28 days (1292 participants, 12 trials, relative risk 0.69, 95% confidence interval [95% CI] 0.48-0.99, moderate certainty evidence) and duration of hospitalization (1100 participants, 10 trials, mean difference -3.20 days, 95%CI -5.74 to -0.66, moderate certainty evidence). The intervention may also decrease sepsis and weight at discharge. Based on low certainty evidence, early feeding may have little to no effect on necrotizing enterocolitis, feed intolerance, and days to regain birth weight. The evidence is very uncertain regarding the effect of initiation time on intraventricular hemorrhage, length, and head circumference at discharge. CONCLUSIONS Enteral feeding within 72 hours after birth likely reduces the risk of mortality and length of hospital stay, may reduce the risk of sepsis, and may reduce weight at discharge.

Abstract
Objective To investigate whether feeding extensively hydrolysis protein formula during the NICU hospitalization was more beneficial for preterm infants with a gestational age (GA) ≤34 weeks when breastfeeding was not possible. Methods In total, 587 preterm infants were randomly divided into two groups: observation groups fed with extensively hydrolyzed formula (EHF) milk and control groups fed with standard preterm formula (SPF) milk until discharge from the neonatal intensive care unit (NICU). The incidence of complications during hospitalization was recorded in both groups. Then, two groups were uniformly fed with 0-to-6-month infant formula milk and followed-up for 6 months after discharge. Results The final study included 370 premature infants, including 185 babies in the observation group and 185 in the control group. In contrast to the SPF, feeding EHF among preterm infants of GA <34 weeks during NICU hospitalization significantly reduced the incidence of feeding intolerance (FI) (14.1 vs. 30.3%, p < 0.01). The incidence of necrotizing enterocolitis (NEC) was significantly reduced in the observation group (2.2 vs. 6.5%, p < 0.05), but there was no significant difference in the incidence of other related complications. At discharge, there was no difference in total serum protein (46.6 vs. 46.4 g/L), albumin (33.5 vs. 34.2 g/L), and calcium (2.37 vs. 2.35 mmol/L), but the serum phosphorus concentrations associated with skeletal mineralization (2.10 vs. 2.22 mmol/L, p < 0.05) was significantly reduced and alkaline phosphatase significantly rose (254 vs. 220 IU/L, p < 0.05) in the observation group. No significant difference was found in the growth rates of body weight, head circumference, or body length, either during the NICU hospitalization or during the 6-month follow-up after discharge (p > 0.05). Conclusions Feeding premature infants of GA ≤34 weeks with EHF reduced the incidence of FI, but had no advantage in establishing whole intestinal nutrition, shortening parenteral nutrition (PN) time, or hospitalization time. It had little effect on physical growth or development during NICU hospitalization and within 6 months after discharge. However, it may increase the incidence of metabolic bone disease (MBD).

Abstract
OBJECTIVES To study the influence of enteral feeding initiation time on intestinal flora and metabolites in very low birth weight (VLBW) infants. METHODS A total of 29 VLBW infants who were admitted to the Department of Neonatology, Children's Hospital of Chongqing Medical University, from June to December, 2020, were enrolled as subjects. According to the enteral feeding initiation time after birth, the infants were divided into two groups: <24 hours (n=15) and 24-72 hours (n=14). Fecal samples were collected at weeks 2 and 4 of hospitalization, and 16S rDNA high-throughput sequencing and gas chromatography-mass spectrometry were used to analyze the microflora and short-chain fatty acids (SCFAs) respectively in fecal samples. RESULTS The analysis of microflora showed that there was no significant difference between the two groups in Chao index (reflecting the abundance of microflora) and Shannon index (reflecting the diversity of microflora) at weeks 2 and 4 after birth (P>0.05). The analysis of flora composition showed that there was no significant difference in the main microflora at the phylum and genus levels between the two groups at weeks 2 and 4 after birth (P>0.05). The comparison of SCFAs between the two groups showed that the <24 hours group had a significantly higher level of propionic acid than the 24-72 hours group at week 4 (P<0.05), while there was no significant difference in the total amount of SCFAs and the content of the other SCFAs between the two groups (P>0.05). CONCLUSIONS Early enteral feeding has no influence on the diversity and abundance of intestinal flora in VLBW infants, but enteral feeding within 24 hours can increase the level of propionic acid, a metabolite of intestinal flora.

Abstract
BACKGROUND Enteral feeding for very preterm or very low birth weight (VLBW) infants is often delayed for several days after birth due to concern that early introduction of feeding may not be tolerated and may increase the risk of necrotising enterocolitis. Concerns exist, however, that delaying enteral feeding may diminish the functional adaptation of the gastrointestinal tract and prolong the need for parenteral nutrition with its attendant infectious and metabolic risks. OBJECTIVES To determine the effects of delayed introduction of progressive enteral feeds on the risk of necrotising enterocolitis, mortality and other morbidities in very preterm or VLBW infants. SEARCH METHODS Search strategies were developed by an information specialist in consultation with the review authors. The following databases were searched in October 2021 without date or language restrictions: CENTRAL (2021, Issue 10), MEDLINE via OVID (1946 to October 2021), Embase via OVID (1974 to October 2021), Maternity and Infant Care via OVID (1971 to October 2021), CINAHL (1982 to October 2021). We also searched for eligible trials in clinical trials databases, conference proceedings, previous reviews, and reference lists of retrieved articles. SELECTION CRITERIA Randomised controlled trials that assessed the effects of delayed (four or more days after birth) versus earlier introduction of progressive enteral feeds on necrotising enterocolitis, mortality and other morbidities in very preterm or VLBW infants. DATA COLLECTION AND ANALYSIS Two review authors separately evaluated trial risk of bias, extracted data, and synthesised effect estimates using risk ratio (RR), risk difference (RD), and mean difference. We used the GRADE approach to assess the certainty of evidence for effects on necrotising enterocolitis, mortality, feed intolerance, and invasive infection. MAIN RESULTS We included 14 trials in which a total of 1551 infants participated. Potential sources of bias were lack of clarity on methods to generate random sequences and conceal allocation in half of the trials, and lack of masking of caregivers or investigators in all of the trials. Trials typically defined delayed introduction of progressive enteral feeds as later than four to seven days after birth and early introduction as four days or fewer after birth. Infants in six trials (accounting for about half of all of the participants) had intrauterine growth restriction or circulatory redistribution demonstrated by absent or reversed end-diastolic flow velocities in the fetal aorta or umbilical artery. Meta-analyses showed that delayed introduction of progressive enteral feeds may not reduce the risk of necrotising enterocolitis (RR 0.81, 95% confidence interval (CI) 0.58 to 1.14; RD -0.02, 95% CI -0.04 to 0.01; 13 trials, 1507 infants; low-certainty evidence due risk of bias and imprecision) nor all-cause mortality before hospital discharge (RR 0.97, 95% CI 0.70 to 1.36; RD -0.00, 95% CI -0.03 to 0.03; 12 trials, 1399 infants; low-certainty evidence due risk of bias and imprecision). Delayed introduction of progressive enteral feeds may slightly reduce the risk of feed intolerance (RR 0.81, 95% CI 0.68 to 0.97; RD -0.09, 95% CI -0.17 to -0.02; number needed to treat for an additional beneficial outcome = 11, 95% CI 6 to 50; 6 trials, 581 infants; low-certainty evidence due to risk of bias and imprecision) and probably increases the risk of invasive infection (RR 1.44, 95% CI 1.15 to 1.80; RD 0.10, 95% CI 0.04 to 0.15; number needed to treat for a harmful outcome = 10, 95% CI 7 to 25; 7 trials, 872 infants; moderate-certainty evidence due to risk of bias). AUTHORS' CONCLUSIONS: Delaying the introduction of progressive enteral feeds beyond four days after birth (compared with earlier introduction) may not reduce the risk of necrotising enterocolitis or death in very preterm or VLBW infants. Delayed introduction may slightly reduce feed intolerance, and probably increases the risk of invasive infection.

Abstract
BACKGROUND Providing enteral feeds to preterm very low birth-weight (VLBW) infants is critical to optimize nutrition, enhance growth, and reduce complications. Protocols guiding feeding practices can improve outcomes, but significant variation exists between institutions, which may limit their utility. To be most effective, protocols should be based on the best available evidence. PURPOSE To examine the state of the science on several key components of feeding protocols for VLBW infants. SEARCH STRATEGY The authors searched PubMed, CINAHL, and EMBASE databases for terms related to feeding VLBW infants less than 32 weeks' gestational age, including initiation of feedings, rate of feeding advancement, timing of human milk (HM) fortification, and feeding during blood transfusions, when diagnosed with a patent ductus arteriosus (PDA) and during medical treatment of PDA closure. RESULTS Initiation of feeds within the first 3 days of life and advancement by 30 mL/kg/d may decrease time to attain full feeds without increasing complications. Insufficient evidence guides optimal timing of HM fortification, as well as feeding infants undergoing blood transfusions, infants diagnosed with a PDA, and infants receiving medical treatment of PDA closure. IMPLICATIONS FOR PRACTICE Integration of existing research regarding feeding initiation and advancement into feeding protocols may improve outcomes. Infants at highest risk of feeding-related complications may benefit from a personalized feeding approach. IMPLICATIONS FOR RESEARCH Additional research is needed to provide evidence concerning the optimal timing of HM fortification and feeding strategies for infants undergoing blood transfusions and those diagnosed with a PDA or receiving medical treatment of PDA closure to incorporate into evidence-based feeding protocols.

Abstract
BACKGROUND Early enteral feeding practices are potentially modifiable risk factors for necrotising enterocolitis (NEC) in very preterm or very low birth weight (VLBW) infants. Observational studies suggest that conservative feeding regimens, including slowly advancing enteral feed volumes, reduce the risk of NEC. However, it is unclear whether slow feed advancement may delay establishment of full enteral feeding, and if it could be associated with infectious morbidities secondary to prolonged exposure to parenteral nutrition. OBJECTIVES To determine the effects of slow rates of enteral feed advancement on the risk of NEC, mortality, and other morbidities in very preterm or VLBW infants. SEARCH METHODS We searched CENTRAL (2020, Issue 10), Ovid MEDLINE (1946 to October 2020), Embase via Ovid (1974 to October 2020), Maternity and Infant Care database (MIDIRS) (1971 to October 2020), CINAHL (1982 to October 2020), and clinical trials databases and reference lists of retrieved articles for eligible trials. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials that assessed effects of slow (up to 24 mL/kg/d) versus faster rates of advancement of enteral feed volumes on the risk of NEC in very preterm or VLBW infants. DATA COLLECTION AND ANALYSIS Two review authors separately evaluated trial risk of bias, extracted data, and synthesised effect estimates using risk ratio (RR), risk difference (RD), and mean difference. We used the GRADE approach to assess the certainty of evidence. Outcomes of interest were NEC, all-cause mortality, feed intolerance, and invasive infection. MAIN RESULTS We included 14 trials involving a total of 4033 infants (2804 infants participated in one large trial). None of the trials masked parents, caregivers, or investigators. Risk of bias was otherwise low. Most infants were stable very preterm or VLBW infants of birth weight appropriate for gestation. About one-third of all infants were extremely preterm or extremely low birth weight (ELBW), and about one-fifth were small for gestational age, growth-restricted, or compromised as indicated by absent or reversed end-diastolic flow velocity in the foetal umbilical artery. Trials typically defined slow advancement as daily increments of 15 to 24 mL/kg, and faster advancement as daily increments of 30 to 40 mL/kg. Meta-analyses showed that slow advancement of enteral feed volumes probably has little or no effect on the risk of NEC (RR 1.06, 95% confidence interval (CI) 0.83 to 1.37; RD 0.00, 95% CI -0.01 to 0.02; 14 trials, 4026 infants; moderate-certainty evidence) or all-cause mortality prior to hospital discharge (RR 1.13, 95% CI 0.91 to 1.39; RD 0.01, 95% CI -0.01 to 0.02; 13 trials, 3860 infants; moderate-certainty evidence). Meta-analyses suggested that slow advancement may slightly increase feed intolerance (RR 1.18, 95% CI 0.95 to 1.46; RD 0.05, 95% CI -0.02 to 0.12; 9 trials, 719 infants; low-certainty evidence) and may slightly increase the risk of invasive infection (RR 1.14, 95% CI 0.99 to 1.31; RD 0.02, 95% CI -0.00 to 0.05; 11 trials, 3583 infants; low-certainty evidence). AUTHORS' CONCLUSIONS The available trial data indicate that advancing enteral feed volumes slowly (daily increments up to 24 mL/kg) compared with faster rates probably does not reduce the risk of NEC, death, or feed intolerance in very preterm or VLBW infants. Advancing the volume of enteral feeds at a slow rate may slightly increase the risk of invasive infection.

Abstract
IMPORTANCE Fortification of expressed breast milk (EBM) using commercially available human milk fortifiers (HMF) increases short-term weight and length in preterm very low-birth-weight (VLBW) neonates. However, the high cost and increased risk of feed intolerance limit their widespread use. Preterm formula powder fortification (PTF) might be a better alternative in resource-limited settings. OBJECTIVE To demonstrate that fortification of EBM by preterm formula powder is noninferior to fortification by HMF, in terms of short-term weight gain, in VLBW neonates. DESIGN, SETTING, AND PARTICIPANTS Open-label, noninferiority, randomized trial conducted from December 2017 to June 2019 at a level 3 neonatal unit in India. The trial enrolled preterm (born at or before 34 weeks of gestation) VLBW neonates receiving at least 100 mL/kg/d of feeds and consuming 75% of milk or more as EBM. INTERVENTIONS Neonates were randomly assigned to receive fortification by either PTF or HMF. Calcium, phosphorus, iron, vitamin D, and multivitamins were supplemented in PTF and only vitamin D in the HMF group to meet the recommended dietary allowances. MAIN OUTCOMES AND MEASURES The primary outcome was the weight gain until discharge from the hospital or 40 weeks' postmenstrual age, whichever was earlier; the prespecified noninferiority margin was 2 g/kg/d. Secondary outcomes included morbidities such as necrotizing enterocolitis, feed intolerance, and extrauterine growth restriction (<10th percentile on the Fenton chart at 40 weeks' postmenstrual age). RESULTS Of the 123 neonates enrolled, 60 and 63 were randomized to the PTF and HMF groups, respectively. The mean gestation (30.5 vs 29.9 weeks) and birth weight (1161 vs 1119 g) were comparable between the groups. There was no difference in the mean (SD) weight gain between the PTF and HMF groups (15.7 [3.9] vs 16.3 [4.0] g/kg/d; mean difference, -0.5 g/kg/d; 95% CI, -1.9 to 0.7). The lower bound of 95% CI did not cross the noninferiority margin. The incidence of feed intolerance was lower in the PTF group (1.4 vs 6.8 per 1000 patient-days; incidence rate ratio 0.19; 95% CI, 0.04 to 0.95), and fewer neonates required withholding of fortification for 24 hours or more (5% vs 22%; risk ratio, 0.22; 95% CI, 0.07 to 0.75). The incidence of necrotizing enterocolitis stage II or more (0 vs 5%) and extrauterine growth restriction (73% vs 81%) was comparable between the groups. CONCLUSIONS AND RELEVANCE Fortification with preterm formula powder is not inferior to fortification with human milk fortifiers in preterm neonates. Given the possible reduction in feed intolerance and lower costs, preterm formula might be a better option for fortification, especially in resource-restricted settings.

Abstract
INTRODUCTION Critical aspects of time of feed initiation, advancement, and volume of feed increment in preterm neonates remain largely unanswered. METHODS Medline , Embase, CENTRAL and CINAHL were searched from inception until 25th September 2020. Network meta-analysis with the Bayesian approach was used. Randomized controlled trials (RCTs) evaluating preterm neonates ≤32 weeks were included. Feeding regimens were divided based on the following categories: initiation day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); advancement day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); increment volume: small volume (SV) (<20 mL/kg/day), moderate volume (MoV) (20-< 30 mL/kg/day), and large volume (≥30 mL/kg/day); and full enteral feeding from the first day. Sixteen regimens were evaluated. Combined outcome of necrotizing enterocolitis (NEC) stage ≥ II or mortality before discharge was the primary outcome. RESULTS A total of 39 studies enrolled around 6,982 neonates. Early initiation (EI) with moderately early or late advancement using MoV increment enteral feeding regimens appeared to be most efficacious in decreasing the risk of NEC or mortality when compared to EI and early advancement with SV increment (risk ratio [95% credible interval]: 0.39 [0.12, 0.95]; 0.34 [0.10, 0.86]) (GRADE-very low). CONCLUSIONS Early initiated, moderately early, or late advanced with MoV increment feeding regimens might be most appropriate in decreasing the risk of NEC stage ≥II or mortality. In view of the certainty of evidence being very low, adequately powered RCTs evaluating these 2 strategies are warranted.

Abstract
BACKGROUND Preterm neonates not fed an exclusive human-milk diet in the neonatal intensive care unit (NICU) show disproportionate postnatal growth. There are scant data on postnatal growth in neonates from India fed an exclusive expressed breast milk (EBM) diet. This study describes the postnatal changes in weight, length, and head circumference in preterm neonates given EBM with selected fortification. METHODS The study had a prospective observational design. Exclusive EBM feeding, early initiation, and standardized progression of feeds was followed. Fortification of breast milk with human milk fortifier (HMF) or liquid calcium phosphate and multivitamins (CALVIT) or hindmilk (HM) was done based on the gestational age. Monitoring for weight, length, and head circumference was done from admission to discharge. RESULTS Ninety-three preterm neonates were included in the study, of which 34 (36.6%) were small for gestational age. Thirty-two (34.3%) neonates received EBM with HMF, 35 (35.7%) received EBM fortified with CALVIT and 26 (28%) neonates received HM fortification. There was a significant difference in the change in z-scores from birth to discharge for the weight, length, and head circumference (P = .001). The mean increase in daily weight ranged from 8.8 to 9.5 g/d, whereas weekly change in length was 0.8-0.9 cm/wk, and head circumference was 0.7 cm/wk. CONCLUSION Postnatal growth of preterm neonates during NICU admission on exclusive EBM feeding with selected fortification resulted in a proportionate increase in weight, length, and head circumference.

Abstract
Early enteral feeding is a potentially modifiable risk factor for necrotising enterocolitis (NEC) and late onset sepsis (LOS), however enteral feeding practices for preterm infants are highly variable. High-quality evidence is increasingly available to guide early feeding in preterm infants. Meta-analyses of randomised trials indicate that early trophic feeding within 48 h after birth and introduction of progressive enteral feeding before 4 days of life at an advancement rate above 24 ml/kg/day can be achieved in clinically stable very preterm and very low birthweight (VLBW) infants, without higher mortality or incidence of NEC. This finding may not be generalisable to high risk infants such as those born small for gestational age (SGA) or following absent/reversed end diastolic flow velocity (AREDFV) detected antenatally on placental Doppler studies, due to the small number of such infants in existing trials. Trials targeting such high-risk preterm infants have demonstrated that progressive enteral feeding started in the first 4 days is safe and does not lead to higher NEC or mortality; however, there is a paucity of data to guide feeding advancement in such infants. There is little trial evidence to support bolus or continuous gavage feeding as being superior in clinically stable preterm infants. Trials that examine enteral feeding are commonly unblinded for technical and practical reasons, which increases the risk of bias in such trials, specifically when considering potentially subjective outcome such as NEC and LOS; future clinical trials should focus on objective, primary outcome measures such as all-cause mortality, long term growth and neurodevelopment. Alternatively, important short-term outcomes such as NEC could be used with blinded assessment.

Abstract
BACKGROUND Artificial formula can be manipulated to contain higher amounts of macro-nutrients than maternal breast milk but breast milk confers important immuno-nutritional advantages for preterm or low birth weight (LBW) infants. OBJECTIVES To determine the effect of feeding preterm or LBW infants with formula compared with maternal breast milk on growth and developmental outcomes. SEARCH METHODS We used the standard strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2018, Issue 9), and Ovid MEDLINE, Ovid Embase, Ovid Maternity & Infant Care Database, and CINAHL to October 2018. We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles.

Such trials are unlikely to be conducted because of the difficulty of allocating an alternative form of nutrition to an infant whose mother wishes to feed with her own breast milk. Maternal breast milk remains the default choice of enteral nutrition because observational studies, and meta-analyses of trials comparing feeding with formula versus donor breast milk, suggest that feeding with breast milk has major immuno-nutritional advantages for preterm or low birth weight infants.

Abstract
BACKGROUND When sufficient maternal breast milk is not available, alternative forms of enteral nutrition for preterm or low birth weight (LBW) infants are donor breast milk or artificial formula. Donor breast milk may retain some of the non-nutritive benefits of maternal breast milk for preterm or LBW infants. However, feeding with artificial formula may ensure more consistent delivery of greater amounts of nutrients. Uncertainty exists about the balance of risks and benefits of feeding formula versus donor breast milk for preterm or LBW infants. OBJECTIVES To determine the effect of feeding with formula compared with donor breast milk on growth and development in preterm or low birth weight (LBW) infants. SEARCH METHODS We used the Cochrane Neonatal search strategy, including electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 5), Ovid MEDLINE, Embase, and the Cumulative Index to Nursing and Allied Health Literature (3 May 2019), as well as conference proceedings, previous reviews, and clinical trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials (RCTs) comparing feeding with formula versus donor breast milk in preterm or LBW infants. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and risk of bias and extracted data independently. We analysed treatment effects as described in the individual trials and reported risk ratios (RRs) and risk differences (RDs) for dichotomous data, and mean differences (MDs) for continuous data, with respective 95% confidence intervals (CIs). We used a fixed-effect model in meta-analyses and explored potential causes of heterogeneity in subgroup analyses. We assessed the certainty of evidence for the main comparison at the outcome level using GRADE methods. MAIN RESULTS Twelve trials with a total of 1879 infants fulfilled the inclusion criteria. Four trials compared standard term formula versus donor breast milk and eight compared nutrient-enriched preterm formula versus donor breast milk. Only the five most recent trials used nutrient-fortified donor breast milk. The trials contain various weaknesses in methodological quality, specifically concerns about allocation concealment in four trials and lack of blinding in most of the trials. Most of the included trials were funded by companies that made the study formula.Formula-fed infants had higher in-hospital rates of weight gain (mean difference (MD) 2.51, 95% confidence interval (CI) 1.93 to 3.08 g/kg/day), linear growth (MD 1.21, 95% CI 0.77 to 1.65 mm/week) and head growth (MD 0.85, 95% CI 0.47 to 1.23 mm/week). These meta-analyses contained high levels of heterogeneity. We did not find evidence of an effect on long-term growth or neurodevelopment. Formula feeding increased the risk of necrotising enterocolitis (typical risk ratio (RR) 1.87, 95% CI 1.23 to 2.85; risk difference (RD) 0.03, 95% CI 0.01 to 0.05; number needed to treat for an additional harmful outcome (NNTH) 33, 95% CI 20 to 100; 9 studies, 1675 infants).The GRADE certainty of evidence was moderate for rates of weight gain, linear growth, and head growth (downgraded for high levels of heterogeneity) and was moderate for neurodevelopmental disability, all-cause mortality, and necrotising enterocolitis (downgraded for imprecision). AUTHORS' CONCLUSIONS In preterm and LBW infants, moderate-certainty evidence indicates that feeding with formula compared with donor breast milk, either as a supplement to maternal expressed breast milk or as a sole diet, results in higher rates of weight gain, linear growth, and head growth and a higher risk of developing necrotising enterocolitis. The trial data do not show an effect on all-cause mortality, or on long-term growth or neurodevelopment.

Abstract
Background: Feed intolerance is common in growth-restricted infants with antenatal AREDF (absent or reverse end-diastolic flow) and presumed to be more severe in those with reverse end diastolic flow (REDF). Natural history of feeding in REDF is rarely reported in the literature.Aims and objectives: To determine the incidence of feed intolerance and necrotizing enterocolitis (NEC) in neonates with antenatal REDF.Design: Preterm inborn neonates with gestation <37 weeks with antenatal REDF diagnosed between January 2015 and September 2017 were included in this retrospective cohort study. The primary outcome was the proportion of neonates having feed intolerance and NEC till discharge or death or transfer to other hospitals and time to achieve full enteral feeding (150 ml/kg/day).Results: Out of total 67 born with antenatal REDF, 8 were transferred out within 48 hours, 8 records not available and 4 excluded due to major malformations. The mean (SD) gestation and birth weight of the remaining 48 neonates were 32 (2) weeks and 1096 (291) g. The median (IQR) age of initiation of feeds was 30 (24-37) hours. Feeds were advanced by median (range) 20 (10-20) ml/kg/day in which 22 babies (45%) had at least 1 episode of feed intolerance at a median (IQR) age of 79 (40-120) hours requiring nil per oral for next 48 (18-96) hours. Full feeds were reached by median age (IQR) of nine (8-12) days. Only 3 neonates (6%) had NEC stage 2 or above as per Bell's staging.Conclusions: Feed intolerance is common in neonates with REDF though the risk of NEC is not high.What is known on this subject?Neonates with antenatal AREDF are at increased risk of feed intolerance and necrotizing enterocolitis.Early introduction of enteral feeds in neonates with AREDF with appropriate monitoring is safe without increased risk of necrotizing enterocolitis.AEDF which progresses to REDF is associated with increased morbidity.What does this study add?Early enteral feeding as early as 24 hours can be initiated in REDF if there are no abdominal symptoms and signs.Feed intolerance is high in REDF cases.The risk of NEC is not higher than what is seen in AEDF cases.

Abstract
BACKGROUND Early enteral feeding practices are potentially modifiable risk factors for necrotising enterocolitis (NEC) in very preterm or very low birth weight (VLBW) infants. Observational studies suggest that conservative feeding regimens, including slowly advancing enteral feed volumes, reduce the risk of NEC. However, slow feed advancement may delay establishment of full enteral feeding and may be associated with metabolic and infectious morbidities secondary to prolonged exposure to parenteral nutrition. OBJECTIVES To determine effects of slow rates of enteral feed advancement on the incidence of NEC, mortality, and other morbidities in very preterm or VLBW infants. SEARCH METHODS We used the standard Cochrane Neonatal search strategy to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5), MEDLINE via PubMed (1966 to June 2017), Embase (1980 to June 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to June 2017). We searched clinical trials databases, conference proceedings, previous reviews, and reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that assessed effects of slow (up to 24 mL/kg/d) versus faster rates of advancement of enteral feed volumes upon the incidence of NEC in very preterm or VLBW infants. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and risk of bias and independently extracted data. We analysed treatment effects in individual trials and reported risk ratio (RR) and risk difference (RD) for dichotomous data, and mean difference (MD) for continuous data, with respective 95% confidence intervals (CIs). We used a fixed-effect model for meta-analyses and explored potential causes of heterogeneity via sensitivity analyses. We assessed the quality of evidence at the outcome level using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS We identified 10 RCTs in which a total of 3753 infants participated (2804 infants participated in one large trial). Most participants were stable very preterm infants of birth weight appropriate for gestation. About one-third of all participants were extremely preterm or extremely low birth weight (ELBW), and about one-fifth were small for gestational age (SGA), growth-restricted, or compromised in utero, as indicated by absent or reversed end-diastolic flow velocity (AREDFV) in the fetal umbilical artery. Trials typically defined slow advancement as daily increments of 15 to 20 mL/kg, and faster advancement as daily increments of 30 to 40 mL/kg. Trials generally were of good methodological quality, although none was blinded.Meta-analyses did not show effects on risk of NEC (typical RR 1.07, 95% CI 0.83 to 1.39; RD 0.0, 95% CI -0.01 to 0.02) or all-cause mortality (typical RR 1.15, 95% CI 0.93 to 1.42; typical RD 0.01, 95% CI -0.01 to 0.03). Subgroup analyses of extremely preterm or ELBW infants, or of SGA or growth-restricted or growth-compromised infants, showed no evidence of an effect on risk of NEC or death. Slow feed advancement delayed establishment of full enteral nutrition by between about one and five days. Meta-analysis showed borderline increased risk of invasive infection (typical RR 1.15, 95% CI 1.00 to 1.32; typical RD 0.03, 95% CI 0.00 to 0.05). The GRADE quality of evidence for primary outcomes was "moderate", downgraded from "high" because of lack of blinding in the included trials. AUTHORS' CONCLUSIONS Available trial data do not provide evidence that advancing enteral feed volumes at daily increments of 15 to 20 mL/kg (compared with 30 to 40 mL/kg) reduces the risk of NEC or death in very preterm or VLBW infants, extremely preterm or ELBW infants, SGA or growth-restricted infants, or infants with antenatal AREDFV. Advancing the volume of enteral feeds at a slow rate results in several days of delay in establishing full enteral feeds and may increase the risk of invasive infection.
