This study evaluated the impact of a seaweed-based feed additive (SBFA) on enteric methane emissions in grazing heifers. Two groups of heifers (n = 11 per group) were maintained on tame pasture under identical conditions. The trial consisted of three phases: a two-week baseline period, a two-week adaptation period, and a seven-week full-dose period. During adaptation, the treatment group received SBFA once daily, with the dosage gradually increased to a target dose of 280 mg bromoform/head per day. This full dose was administered throughout the final phase. Enteric emissions of methane were continuously monitored using the GreenFeed emission monitoring system. During the baseline period, gas emissions were not different between the groups (p = 0.75); however, during the adaptation (p = 0.08) it tended to be lower in the SBFA group compared to the control, and during the full-dose period, methane emissions in the SBFA treatment group were significantly (p < 0.01) lower than in the control group (p < 0.01), averaging 53.7 g/d versus 203.2 g/d, corresponding to a 73.6% reduction in methane. Additionally, a prolonged suppression effect was observed, with methane emissions in the treatment group remaining low for three days after removal of the SBFA compared to the control group (p < 0.01), and on day 4 after the removal, the SBFA treatment group still tended (p = 0.07) to be lower than the control group. These findings indicate that SBFA, when administered once daily, has significant potential for mitigating enteric methane emissions in grazing cattle. Full article

Background/Objectives: Preterm infants often require increased caloric intake to maintain appropriate growth while in the neonatal intensive care unit (NICU). Emerging evidence suggests that alterations of the gut microbiome may play a role in infant and childhood growth patterns. The fecal microbiome patterns in infants with normal and poor growth patterns were classified in this study. Methods: We conducted a prospective trial of infants of less than 29 weeks’ gestation with an embedded case–control analysis of infants with normal or poor growth patterns. Fecal samples were collected weekly from infants on full enteral feeds and analyzed blindly using 16s rRNA next-generation sequencing. The relationship between gut microbial diversity and composition and growth pattern and trajectory were assessed. Results: A total of 115 infants were enrolled in the trial with 263 fecal samples selected from 87 enrolled infants for analysis. In total, 37 samples were available from the normal growth cohort, 56 samples from the poor growth cohort, and 170 samples were available for analysis from the very poor growth cohort. Analysis of relative abundance revealed increased representation of Veillonella, Bifidobacterium, and Clostridium in very poor growth infants compared to normal growth infants. Variation in specific taxa was also found to vary significantly across post-menstrual age depending on the degree of growth failure. Conclusions: Gut microbiome composition and variance was modified by the degree of growth failure in our cohort of preterm infants. Our study adds to the growing body of evidence that alteration of the microbiome is associated with poor growth in preterm infants. This may ultimately represent a therapeutic target for growth failure in preterm infants. Full article

Background/Objectives: The optimal rate of enteral feeding advancement in preterm infants remains uncertain despite decades of clinical research. This uncertainty arises from concerns that rapid feeding progression may increase the risk of feeding intolerance and necrotizing enterocolitis (NEC), two major causes of morbidity and mortality in this population. The feeding rate may also influence intestinal oxygenation due to mesenteric hemodynamic changes during feeding. This study aimed to evaluate whether the rate of enteral feeding advancement (slow vs. rapid) affects intestinal oxygenation and its association with feeding intolerance (FI) or necrotizing enterocolitis in very low birth weight preterm infants. Methods: This prospective, randomized, two-center study included infants born at 28–32 weeks of gestation. Group 1 received slow advancement (20 mL/kg/day) and Group 2 rapid advancement (30 mL/kg/day) of enteral feeds. Splanchnic (srSO₂) and cerebral (crSO₂) oxygenation were monitored daily using the FDA-approved INVOS NIRS device during feeding periods (08:00–16:00). Monitoring was performed during minimal enteral nutrition (Phase 1), advancement phases (Phase 2), and for two days after achieving full enteral feeding (Phase 3). The splanchnic-to-cerebral oxygenation ratio (SCOR) was also calculated. Percentage changes in srSO₂ and SCOR during and after feeding were calculated from baseline (prefeeding) values and analyzed. Results: Sixty infants were enrolled. Mean gestational age and birth weight were 29.76 ± 1.33 weeks and 1375.05 ± 271.19 g, respectively. Group 2 achieved full enteral feeding significantly earlier (p = 0.001), with no other demographic differences between groups. No cases of NEC were observed. Feeding intolerance occurred in 14 infants (23.3%): 8 in Group 1 and 6 in Group 2 (p = 0.192). Both groups exhibited increased srSO₂ and SCOR during feeding; however, the between-group differences were not statistically significant (Phase 2 srSO₂ and SCOR: p = 0.07, 0.08; Phase 3 srSO₂ and SCOR: p = 0.069, 0.071). However, the percentage change from baseline in srSO₂ and SCOR during and after feeding was significantly greater in Group 2 during the advancement and full enteral feeding phases (Phase 2 srSO₂ and SCOR: p = 0.03, 0.022; Phase 3 srSO₂ and SCOR: p = 0.015, 0.048). Infants with feeding intolerance demonstrated significantly lower srSO₂ and SCOR values compared to tolerant infants, and this reduction persisted even after reaching full enteral feeding. ROC analysis suggested gestational age < 30 weeks, birth weight < 1180 g, srSO₂ < 52, and SCOR < 0.6 were associated with feeding intolerance. Conclusions: Intermittent bolus feeding increased intestinal oxygenation, with a more pronounced effect in the rapid advancement group. No difference in gastrointestinal adverse outcomes was observed between groups. Lower intestinal oxygenation was associated with feeding intolerance, and the suggested predictive criteria may help guide individualized feeding strategies. Full article

Background: Human milk (HM) is the optimal nutrition for preterm infants, but supplementation is often required to meet their unique nutritional needs. Donor human milk (DHM) and preterm formula are commonly used alternatives, yet their impacts on bone metabolism and clinical outcomes remain incompletely defined. Objective: To compare the effects of exclusive mother’s own milk (MOM), MOM supplemented with DHM, and MOM supplemented with preterm formula on bone metabolism markers, growth milestones, and clinical outcomes in very preterm and very low birth weight (VLBW) infants. Methods: We conducted a retrospective review of medical records for infants born at <32 weeks’ gestation or <1500 g birth weight between January 2018 and June 2023. Feeding groups included exclusive MOM (N = 135), MOM + DHM (N = 74), and MOM + Formula (N = 54). Biochemical markers were assessed at baseline and on days 7, 14, and 28. Multivariate regression analyses evaluated predictors of growth and clinical outcomes. Results: Infants in the MOM group had significantly lower gestational age and birth weight, with higher rates of respiratory morbidity. Time to full enteral feeding and duration of parenteral nutrition were longer in the MOM group, but feeding regimen was not an independent predictor of these outcomes. By day 14, the MOM group had higher alkaline phosphatase levels and lower phosphorus levels compared to mix feeding groups, but these differences resolved by day 28. Calcium levels varied between groups but remained within normal ranges. Necrotizing Enterocolitis (NEC) incidence did not differ significantly across feeding regimens and was primarily associated with longer parenteral nutrition duration. Conclusions: Supplementation of MOM with either DHM or preterm formula supported adequate growth and bone metabolism without increasing NEC risk. Feeding regimen did not independently influence time to full enteral feeding or length of hospitalization, which were driven primarily by infant maturity and clinical status. Both DHM and preterm formula are viable supplements to MOM, ensuring nutritional adequacy without adverse bone health effects. Prospective studies are needed to evaluate long-term outcomes of these feeding strategies. Full article

Background and Objectives: Transpyloric (TP) feeding tube placement is a viable nutritional strategy in low birth weight infants (LBWIs) with severe gastroesophageal reflux or feeding intolerance. However, technical challenges are encountered in patients of this age group due to their small body size and the limited availability of appropriately sized equipment. Materials and Methods: We retrospectively reviewed 15 endoscopic TP tube placements performed in 12 LBWIs weighing less than 2.5 kg between May 2017 and March 2025. Emphasis was placed on procedural techniques, equipment selection, and troubleshooting strategies for successful bedside execution. Results: All procedures were performed without the use of additional accessories, by advancing a feeding tube preloaded with a guidewire under direct visualization provided by a 5.5 mm outer diameter endoscope. All procedures were technically successful, including 14 performed at the bedside using a portable endoscope. A 6 or 8 Fr feeding tube loaded with a soft-tipped guidewire was advanced through the pylorus under direct endoscopic visualization. The average body weight at the time of the procedure was 1950 ± 296 g. No complications such as mucosal injury, perforation, or tube dislodgement occurred during the procedure. The average enteral feeding volume increased from 33.4 ± 52.8 cc/kg to 92.0 ± 44.4 cc/kg within 7 days. Full enteral nutrition was achieved in all surviving patients within three weeks. The feeding tube remained in place for a mean duration of 26.1 ± 19.2 days. Conclusions: Endoscopic TP tube placement in LBWIs can be safely and reliably performed at the bedside with appropriate technical modifications. It facilitates earlier advancement to full enteral nutrition and may serve as a viable option for LBWIs unresponsive to standard feeding methods. Full article

Background/Objectives: An evidence-based list of key variables regarding jejunoileal atresia (JIA) care needs to be established to enable quality evaluation and optimization of its care. The aim of this study is to provide an overview of reported patient, treatment, and outcome variables for JIA as documented in recent literature. This list has not been developed previously and will be the foundation for a JIA quality indicator set of the European Pediatric Surgery Audit (EPSA). Methods: A systematic review of the literature on the primary care path of JIA, published between 2013 and 2023, was conducted following the PRISMA guidelines. All relevant patient characteristics, parameters regarding JIA treatment, and outcomes were extracted from the included publications. Results: A total of 844 variables were extracted from 94 included articles. One hundred fifty-seven parameters were mentioned in more than 5% of publications. The most mentioned patient characteristics were sex (86%), gestational age (71%), and associated anomalies (66%). The most mentioned treatment parameters were stoma placement (34%), primary anastomosis (41%), and time to full enteral nutrition (24%). Most mentioned outcomes were mortality (70%), length of hospital stay (55%), and complications (60%). Conclusions: This study created an overview of reported patient characteristics, treatment, and outcome variables regarding the treatment of JIA. A focus on the short-term management and outcomes of JIA was observed; frequently discussed topics were perioperative management, surgical techniques, and feeding management. Our results will serve as the foundation for a Delphi study to develop a core indicator set for JIA, enabling benchmarking and measurement of quality of care. Full article

Background: Hypoxic–ischemic encephalopathy (HIE) is a leading cause of severe neurological impairments in childhood. Therapeutic hypothermia (TH) is both safe and effective in neonates born at ≥36 weeks gestation with moderate to severe HIE. We aimed to evaluate short-term outcomes—including brain injury detected on magnetic resonance imaging (MRI)—in infants born at 34–35 weeks of gestation drawing on our clinical experience with neonates under 36 weeks of gestational age (GA). Methods: In this retrospective cohort study, 20 preterm infants with a GA of 34 to 35 weeks and a matched cohort of 80 infants with a GA of ≥36 weeks who were diagnosed with moderate to severe HIE and underwent TH were included. Infants were matched in a 1:4 ratio based on the worst base deficit in blood gas and sex. Maternal and neonatal characteristics, brain MRI findings and short term outcomes were compared. Results: Infants with a GA of 34–35 weeks had a lower birth weight and a higher rate of caesarean delivery (both p < 0.001). Apgar scores, sex, intubation rate in delivery room, blood gas pH, base deficit and lactate were comparable between the groups. Compared to infants born at ≥36 weeks of GA, preterm neonates were more likely to receive inotropes, had a longer time to achieve full enteral feeding, and experienced a longer hospital stay. The mortality rate was 10% in the 34–35 weeks GA group. Neuroimaging revealed injury in 66.7% of infants born at 34–35 weeks of gestation and in 58.8% of those born at ≥36 weeks (p = 0.56). Injury was observed across multiple brain regions, with white matter being the most frequently affected in the 34–35 weeks GA group. Thalamic and cerebellar abnormal signal intensity or diffusion restriction, punctate white matter lesions, and diffusion restriction in the corpus callosum and optic radiations were more frequently detected in infants born at 34–35 weeks of gestation. Conclusions: Our study contributes to the growing body of literature suggesting that TH may be feasible and tolerated in late preterm infants. Larger randomized controlled trials focused on this vulnerable population are necessary to establish clear guidelines regarding the safety and efficacy of TH in late preterm infants. Full article

Background/Objectives: Postnatal growth faltering (PGF) significantly affects premature neonates, leading to compromised neurodevelopment and an increased risk of long-term health complications. Methods: This retrospective study at a level III NICU of a tertiary hospital analyzed 650 preterm neonates born before 33 weeks. Postnatal growth was evaluated using the Fenton2013 and INTERGROWTH-21st growth charts, with changes in weight z-scores from birth to discharge classified as normal growth (ΔZ ≥ −1), non-severe PGF (−2 ≤ ΔZ < −1), and severe PGF (ΔZ < −2). Results: Mean gestational and postmenstrual age at discharge was 30 weeks (SD 1.9) and 37.1 weeks (SD 2.7), respectively. Fenton2013 growth curves revealed a higher prevalence of non-severe and severe PGF (43% and 14.6%) compared to INTERGROWTH-21st (24.5% and 10.3%). A more rapid establishment of full enteral feeds was strongly associated with reduced severe PGF prevalence in both growth charts (p < 0.001), as was shorter hospitalization. Late-onset sepsis was associated with an increased risk of severe PGF, while being small for gestational age (SGA) was protective against severe PGF across both growth charts (p < 0.001). A trend of decreasing PGF prevalence was noted over the study years, most probably attributed to the implementation of updated nutritional guidelines. Interestingly, when machine learning classification models were evaluated in our Greek cohort, a notable decline in predictive accuracy depending on the growth standard applied was observed. Conclusions: Our study highlights the need for standardizing PGF definition in an attempt to enhance nutritional management and further investigate the long-term impacts of nutritional interventions on growth, neurodevelopment, and overall health outcomes.

Background/Objectives: Optimal feeding regimens for preterm neonates, including the role of multi-nutrient fortification, are unknown, leading to large practice variation in comparing different feeding regimens that include fortification and their impact on outcomes for preterm infants. Methods: Using a network meta-analyses design, two reviewers independently extracted data. A Cochrane CENTRAL, Medline, Embase, and CINAHL search was conducted for all studies published up to 27 June 2023. Randomized clinical trials of feeding regimens for preterm infants that included multi-nutrient fortification were included. Outcomes were mortality, necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), sepsis, periventricular leukomalacia (PVL), bronchopulmonary dysplasia (BPD), time to full enteral feeds, and the Bayley II MDI developmental score. Results: Fifty-nine studies were included. For mortality, NEC, and time to reach full enteral feeds, the top-ranked treatment class was the mother’s own milk with donor milk and a human-milk-based fortifier. For ROP and BPD, the top-ranked treatment class was mother’s own milk with a phosphorus fortifier. For sepsis, the top-ranked treatment class was mother’s own milk with formula. For PVL, the top-ranked treatment classes were mother’s own milk and mother’s own milk with donor milk and a bovine fortifier in the two disconnected networks. For the Bayley II MDI score, the top-ranked treatment class was mother’s own milk with formula and bovine fortification. Conclusions: Treatment rankings are consistent with the underlying hypothesis that increased mother’s own milk intake appears to be associated with better clinical outcomes. This review provides the first global view of interventions and highlights insufficient high-quality evidence to support or refute one fortification feeding regimen over another. Full article

Background/Objectives: Nutritional support is a critical yet challenging aspect of care for pediatric patients requiring extracorporeal membrane oxygenation (ECMO). Malnutrition is prevalent in this population and is associated with worse clinical outcomes. This review synthesizes current evidence on nutritional strategies for pediatric ECMO patients, emphasizing assessment methods, feeding routes, challenges, and clinical outcomes. Methods: A literature review was conducted using PubMed, Scopus, and Web of Science to identify relevant studies published between January 2010 and 2025. Keywords included “pediatric ECMO”, “nutrition”, “enteral feeding”, and “parenteral nutrition”. Studies addressing nutritional assessment, enteral and parenteral feeding practices, and their impact on clinical outcomes were included. Results: Malnutrition is a significant risk factor for morbidity and mortality in ECMO patients, yet nutritional support remains highly variable. While enteral nutrition (EN) is preferred, feeding intolerance and gastrointestinal dysfunction often necessitate parenteral nutrition (PN). Early EN initiation, even at trophic levels, is associated with improved gut integrity and outcomes. However, achieving full nutritional goals enterally remains a challenge, particularly in neonates. PN remains essential in cases of feeding intolerance but is linked to hepatic dysfunction and metabolic imbalances. Conclusions: Optimizing nutritional support in pediatric ECMO patients requires individualized assessment and a structured approach to enteral and parenteral feeding. Further research is needed to establish standardized feeding protocols and determine the optimal timing and composition of nutritional support to improve outcomes. Full article

Neonates with congenital heart disease (CHD) are at increased risk of growth failure and necrotizing enterocolitis (NEC), making nutritional management crucial for their outcomes. This study aimed to evaluate the impact of a standardized feeding protocol on growth and NEC incidence in CHD infants. A retrospective study was conducted at a tertiary care center, including neonates diagnosed with CHDs from January 2020 to March 2023. Patients were divided into two groups: those receiving the standardized feeding protocol (protocol group, n = 12) and those who did not (non-protocol group, n = 39). Key metrics such as growth velocity at discharge, anthropometric z score changes at discharge since birth, days to full enteral feeds, NEC incidence, and length of stay were analyzed. Statistical comparisons were made using two-tailed Mann-Whitney test and chi-squared tests. The NEC incidence was 10% in the non-protocol group and 0% in the protocol group (p = 0.25), with no significant difference. All anthropometric growth markers at the time of discharge differed between the groups, with the protocol group demonstrating favorable outcomes across all measured variables; however, these differences did not reach statistical significance. The time to reach full enteral feeds was shorter (8.5 days vs. 11 days; p = 0.22), and length of stay was shorter in the protocol group (17 days vs. 23 days; p = 0.14), although neither was statistically significant. Although the protocol group showed trends towards reduced NEC and improved growth, this was not statistically significant, which could have been because of the small sample size. Our findings suggest that a standardized feeding protocol may reduce the time to full enteral feeds and hospital stay, but further large-scale studies are needed to confirm these results.

Background: Controversy exists about the usefulness of gastric residual (GR) evaluation in preterm infants, and different results have been obtained in studies addressing this practice. Therefore, this meta-analysis aimed to evaluate the efficacy and safety of the practice of routine monitoring of GR compared to avoiding routine aspiration or alternative interventions. Methods: An online database search was conducted for relevant randomized trials from 2017 to 2023. The efficacy of the intervention was assessed from the incidence of necrotizing enterocolitis (NEC) and the time taken for full enteral feeds. The safety was assessed from the duration of hospitalization, incidence of late-onset sepsis, and days of total parenteral nutrition. Results: Only six studies were deemed eligible, fit the inclusion criteria, and were included in the quantitative synthesis. There was no significant difference between the groups in the incidence of NEC, with a mean difference of 0.95 (95% CI: 0.52, 1.75), while the intervention practice showed the early achievement of full enteral feeds (−2.21; 95% CI: −2.58, −1.84), a shorter duration of hospitalization (−0.65; 95% CI: −1.33, 0.02), a lower incidence of late-onset sepsis (0.70; 95% CI: 0.45, 1.09), and less days of total parenteral nutrition −1.65 (95% CI: −1.90, −1.40). Conclusions: For preterm infants with no signs of feeling intolerance, the results from this study stress the omission of the practice of routine gastric residual aspiration. Full article

Background/Objectives: Probiotic supplementation has been actively investigated in preterm populations to reduce the risk of necrotizing enterocolitis (NEC) and late-onset sepsis. Despite this, few studies have focused on clinically relevant feeding tolerance and growth outcomes, and there is an alarming lack of evidence surrounding extremely preterm infants (defined as birth before 28 weeks gestational age), those most at risk of severe comorbidities. We aimed to investigate whether probiotics improve feeding tolerance, neonatal growth and neonatal morbidity among extremely preterm infants. Methods: A literature search was conducted in Medline, Embase, Cochrane CENTRAL, Web of Science, and clinicaltrials.gov for ongoing trials. We included extremely preterm infants from randomized controlled trials and non-randomized trials with a concurrent control group. Two authors independently performed screening, data extraction and risk of bias assessment using the Risk of Bias 2 tool from Cochrane. The certainty of the evidence was assessed using GRADE. Results: Eleven RCTs and three non-randomized studies with a concurrent control group were included, analyzing a total of 14,888 extremely preterm infants. Meta-analyses revealed lower mean days to full enteral feeds (mean difference 1.1 days lower; 95% CI, 7.83 lower to 5.56 higher) and lower duration of parenteral nutrition (mean difference 2.4 days lower; 95% CI, 7.44 lower to 2.58 higher) in infants treated with probiotics; however, this was not statistically significant. There was a significant reduction in NEC (RR; 0.80, 95% CI; 0.68, 0.93) and all-cause mortality (RR; 0.56, 95% CI; 0.33, 0.93) in the probiotic group. All outcomes were graded at low or very low certainty of evidence. Conclusions: The findings indicate a trend towards a potential beneficial effect of probiotic supplementation in reducing feeding intolerance and a notable reduction of risk of NEC and all-cause mortality in infants receiving probiotics. Future RCTs will focus on feeding intolerance, and growth outcomes are warranted. Full article

Background: Newborns, including preterm infants, are capable of responding to pain. Recurrent pain exposure is associated with suboptimal motor development, cognitive impairments, abnormal brain growth, and maladapted nociceptive reactions. Problem: Current agents, primarily opioids and benzodiazepines, raise major concerns due to their adverse effects, including insufficient sedation or analgesia, withdrawal, depressed respiratory effort, tolerance, and occasional paradoxical agitation. Commonly used drugs such as midazolam and morphine have been shown to induce neuroapoptosis and neurodevelopmental abnormalities in animal studies. Evaluation—Dexmedetomidine: As a specific alpha-2 adrenergic agonist, dexmedetomidine causes a significantly lower reduction in breathing effort. It has over 800 times greater affinity for alpha-2 receptors compared to alpha-1 receptors. Common side effects include bradycardia and hypotension. Prolonged use may necessitate a transition to clonidine during the weaning process. Dexmedetomidine can be administered intravenously as a bolus or infusion or intranasally. Indications include sedation and analgesia for mechanical ventilation, therapeutic hypothermia, procedural premedication, and as an adjunct to inhalational anesthesia and nerve-blocking agents. Research across varying age groups has demonstrated that dexmedetomidine shortens periods of invasive ventilation and decreases the need for other sedatives. Neonatal studies suggest that dexmedetomidine may help accelerate the achievement of full enteral feeds and can be safely administered within specific dosage ranges without causing significant adverse events that would necessitate abrupt discontinuation. Conclusions: Dexmedetomidine can be used alone or in combination with other agents. By increasing the use of dexmedetomidine, it is possible to reduce the dosage of concurrent medications, thereby minimizing the risk of complications while still achieving the desired sedation and analgesia.

Background: For infants, withholding or withdrawal of feeding is ethically permissible when the child is imminently dying or chronically and irreversibly comatose. It can also be appropriate in cases of medical futility with a low chance of survival. However, there is much contention in situations where the medical prognosis is uncertain. Case presentation: Annie is a 6-week-old neonate with antenatally acquired cystic encephalomalacia, a chronic non-progressive neurological condition. Her future neurological outcome is uncertain. She is putting on weight in the NICU with stable cardiorespiratory status on room air and tolerates full nasogastric tube feeding but requires frequent oropharyngeal suctioning. Her parents ask to stop tube feeding and allow Annie to die. They deem she has a poor quality of life and is experiencing tremendous suffering. Discussion: Parents’ perceptions of “best interest” and “physical suffering” are explored, alongside those of the healthcare team. Concomitant issues like feeding withdrawal and moral distress are examined in context—that of a newborn where developmental outcomes and disease trajectory are unclear. Conceptual frameworks, empirical evidence and consensus-based ethics guidelines informed a rich and multi-dimensional exposition of a difficult and value-laden decision. Conclusions: While instinctively legitimate, enteral feeding in an infant, in this case with severe neurological impairment, is ultimately still a medical intervention. In contrast to prevailing conventions within adult medicine, the careful and nuanced consideration of benefits and burdens from different stakeholders’ perspectives is critical before any deliberate withdrawal to allow natural death.
