Background: Nutrition is of paramount importance during early development, since suboptimal growth in this period of life is linked to adverse long- and mid-term outcomes. This is particularly relevant for preterm infants, who fail to thrive during the first weeks of life and develop extrauterine growth restriction (EUGR). This group of premature babies represents an interesting population to investigate using a metabolomic approach to optimize nutritional intake. Aims: To analyse and compare the urinary metabolomic pattern at birth of preterm infants with and without growth restriction at 36 weeks of postmenstrual age or at discharge, searching for putative markers of growth failure. Methods: We enrolled preterm infants between 23 and 32 weeks of gestational age (GA) and/or with a birth weight <1500 g, admitted to the Neonatal Intensive Care Unit (NICU) at the Department of Women’s and Children’s Health of Padova University Hospital. We collected urinary samples within 48 h of life and performed untargeted metabolomic analysis using mass spectrometry. Results: Sixteen EUGR infants were matched with sixteen non-EUGR controls. The EUGR group showed lower levels of L-cystathionine, kynurenic acid, L-carnosine, N-acetylglutamine, xanthurenic acid, aspartylglucosamine, DL5-hydroxylysine-hydrocloride, homocitrulline, and L-aminoadipic acid, suggesting a lower anti-inflammatory and antioxidant status with respect to the non-EUGR group. Conclusions: Metabolomic analysis suggests a basal predisposition to growth restriction, the identification of which could be useful for tailoring nutritional approaches. Full article

Background: Prematurity and low birth weight (LBW) drive infant morbidity and mortality, requiring nutritional interventions, especially in food-insecure settings. In Indonesia, regional disparities in food security hinder adequate nutrition for premature and LBW infants, exacerbating health challenges. The aim of study is to investigate and determine factors associated with prematurity and LBW in children from food-insecure and food-secure households. Methods: This research employed a cross-sectional study with 657 mothers of children aged 36–59 months, conducted using random sampling. Data was collected via standardized questionnaires and analyzed using Chi-square tests and logistic regression. Results: The adjusted model showed that children of food-insecure households had a higher risk of LBW (AOR = 0.54; 95% CI: 0.29–0.99; p < 0.05). LBWs were found to significantly less occur in food-insecure households. Low maternal education was associated with an increased risk of preterm birth (AOR = 3.23; 95% CI:1.78–5.84; p < 0.001). Furthermore, prematurity correlated with house ownership (p < 0.01), indicating the household’s wealth condition. Maternal education and house ownership were linked to prematurity, indicating the risk to child health outcomes. In summary, maternal education, employment status, and household income were linked to food insecurity, indicating the risk to child health outcomes. Conclusion: Strategies to improve child health outcomes are essential, including enhancing maternal nutrition knowledge to improve child feeding practices, promoting gender equality in career development, and reducing food insecurity in households.

Background/Objective(s): Post-discharge clinical needs of extremely preterm (EP) infants are not well defined. The aim of this study is to evaluate healthcare utilization after discharge in infants born EP and compare it to the general pediatric population. Methods: This study involved a post hoc analysis of infants born 24-0/7 to 27-6/7 weeks’ gestation enrolled in the Preterm Erythropoietin Neuroprotection (PENUT) Trial who had at least one follow-up survey representing their course between 24 and 60 months of age. The results were compared to the general population data from the Kids’ Inpatient Database, Nationwide Emergency Department Sample, and National Health and Nutrition Examination Survey. Results: Maternal, infant, and hospitalization characteristics for PENUT infants who survived to discharge (n = 828) compared to those with follow-up (n = 569) were similar except for race and maternal age. Overall, EP infants had an overall lower rate of ED visits (31% vs. 68%) but a higher rate of hospitalizations (11% vs. 3%). EP infants were less likely to go to the ED for gastrointestinal (5% vs. 12%) and dermatologic (1% vs. 6%) concerns but more likely to go to the ED for procedures (7% vs. <1%). EP infants had a higher rate of medication use (56% vs. 14%) in all categories except psychiatric medications. Conclusions: While EP infants had higher rates of specialty healthcare utilization relative to the general pediatric population, they were less likely to visit the ED overall, particularly for common concerns in this age range. This may reflect improved access and navigation of the healthcare system by EP caregivers. Full article

Background/Objectives: Breast milk donation is increasingly recognized as a vital public health resource, providing optimal nutrition for infants who cannot be breastfed by their biological mothers. Human milk banks play a crucial role in supporting infant health, particularly for preterm and medically vulnerable infants. Despite its recognized benefits, the practice of breast milk donation and utilization remains influenced by a complex interplay of individual, social, and cultural factors. Methods: This study systematically examines how demographic and sociocultural variables are associated with attitudes and behaviors related to breast milk donation. Data were collected from 1223 Israeli mothers via questionnaires distributed through WhatsApp groups between April and May 2025. By analyzing the questionnaire results, the research identified key predictors of willingness to donate and use donated milk, as well as patterns of awareness and perceived support within different population groups. Results: Higher education (χ² = 12.87, p = 0.0016) and settlement type (χ² = 83.096, p = 0.000) were significantly associated with greater willingness to donate breast milk. Income level had no effect on donation behavior, though higher-income participants were more open to its use (χ² = 86.838, p = 0.000). Lifestyle also influenced perceptions of social support (F(2, 1220) = 259.4036, p < 0.001) and cultural support (F(2, 1220) = 601.2383, p < 0.001) of milk donation and use. Significant correlation was found between perceived cultural and social support (t = 5.140, p = 0.000), emphasizing their interrelated influence on milk donation attitudes. Conclusions: The findings assist in guiding the development of public health policies, as well as targeted awareness campaigns, to promote equitable access to donor milk services across varied communities. From the public health perspective, the findings of this study can orientate campaigns that encourage both donation and use of breast milk focusing on segments of the population in which the level of awareness is relatively low.

Salivary cortisol is widely used to assess stress and circadian rhythms, yet its control variables in neonates, particularly regarding postnatal age, remain poorly understood. To elucidate age-specific effects of clinical variables on cortisol levels, 91 neonates with a mean (standard deviation) gestational age of 34.2 (3.8) weeks and postnatal age of 38.3 (35.4) days were categorised into Early, Medium, and Late groups by quartiles (days 10 and 56). Interactions with postnatal age were evaluated by comparing Early-to-Medium or Early-to-Late differences in regression coefficients between independent variables and cortisol levels. In the whole cohort, maternal hypertensive disorders of pregnancy and morning sampling were associated with reduced cortisol levels (both p = 0.001). Mean regression coefficients (95% CI) between variables and cortisol levels were as follows: for postconceptional age, Early, −0.102 (−0.215, 0.010) and Late, 0.065 (−0.203, 0.332) (p = 0.035); for feeding duration, Early, 0.796 (−0.134, 1.727) and Late, −0.702 (−2.778, 1.376) (p = 0.010); for time elapsed since feeding, Early, −0.748 (−1.275, −0.221) and Late, −0.071 (−1.230, 1.088) (p = 0.036); and for blood lactate, Early, 0.086 (0.048 to 0.124), Medium, 0.022 (−0.063, 0.108), and Late, −0.018 (−0.106, 0.070) (p = 0.008 and <0.001 vs. Medium and Late, respectively). The influence of postconceptional age, oral feeding, and anaerobic metabolism on salivary cortisol levels was observed during the birth transition period but not beyond 10 days of life. Given the age-specific dependence of cortisol levels on clinical variables, including postconceptional age, feeding, and oxygen metabolism, caution is warranted when interpreting findings from studies on salivary cortisol in newborn infants.

As the limit of viability is extended to lower gestational ages, neonatologists caring for preterm infants must discover the optimal nutritional combination to support postnatal growth. It has been well established that introducing protein soon after birth is associated with improved short-term growth at 36 weeks postmenstrual age and neurodevelopment. However, it remains unclear what the optimal level of protein is for parenteral nutrition at various gestational ages. Several studies have shown possible adverse effects of high-protein delivery in very low birth weight infants. Inborn errors in amino acid metabolism also caution us that higher levels of specific amino acids can harm the growing brain. Full article

The complications observed in preterm infants are largely attributable to underdeveloped organ systems and inadequate nutritional stores at birth. Insufficient nutritional support can further exacerbate persistent sequelae, such as bronchopulmonary dysplasia (BPD), metabolic bone disease of prematurity (MBDP), and retinopathy of prematurity (ROP). As a result, clinicians have collaborated to develop optimal nutrition strategies for preterm neonates. However, these clinical nutrition plans may be hindered by several factors, including fluid restrictions due to patent ductus arteriosus (PDA) and delayed enteral nutrition following necrotizing enterocolitis (NEC). Modified strategies for specific conditions can help prevent further deterioration, but inadequate nutritional support may limit organ growth and contribute to additional complications. Achieving an optimal balance between nutritional support and managing specific medical conditions varies across institutions. In addition to fluid balance and energy intake, supplementary nutrition—such as vitamins and probiotics—plays a crucial role in disease prevention. Drawing on recent evidence and our clinical experiences with neonatal nutritional strategies, this review article summarizes the specialized nutritional management required for preterm neonates with conditions such as BPD, NEC, MBDP, PDA, and ROP.

Background/Objectives: Lactating mothers have increased nutritional requirements, but nutritional adequacy is difficult to achieve. Additionally, human milk (HM) composition depends on maternal diet. However, the nutritional intake and status of mothers with hospitalized very preterm infants (MHVPIs) (<32 weeks of gestational age) have rarely been assessed. Hence, the aim of the present study was to determine the intake of macronutrients, micronutrients, and lipids, as well as the nutritional status of MHVPIs. The results were compared with a group of HM donors (HMDs), and associations with HM composition were evaluated using multiple linear regression. Methods: For dietary assessment, a 5-day dietary record including supplement intake was completed by 15 MHVPIs and 110 HMDs. Vitamins and fatty acids (FA) were determined in plasma and erythrocytes; minerals and methylmalonic acid were determined in urine; and macronutrients, vitamins, minerals, and the lipid profile were determined in HM. Results: Considering dietary reference intakes, the dietary evaluation of MHVPIs revealed a high percentage of inadequate nutrient intake in relation to total energy, as well as for iodine and vitamins B8, B9, C, D, and E. A high protein intake was observed. The percentage of energy from carbohydrates was low, whereas the percentage of energy from fat was high. However, the diet of MHVPIs did not differ substantially from the diet of HMDs. Associations were observed between the study groups (MHVPI vs. HMD) and the HM concentration of protein, several micronutrients, and fatty acids independent from intake and status. Conclusions: Deficient nutrient intakes did not appear to be exclusively related to MHVPI but rather seemed to be widespread in both study groups. However, for preterm infants, an insufficient supply of nutrients is critical and should be addressed in order to improve preterm infant’s outcomes. Furthermore, we provided additional insights into the exploration of HM by relating its composition to prematurity. Full article

Background/Objectives: Body composition plays a crucial role in neurodevelopment and the long-term health of preterm and term infants. Air displacement plethysmography (ADP), especially with the PEAPOD^® system, is well established in research and increasingly explored in clinical practice. Building on our team’s earlier experiences, this study aimed to (1) evaluate the safety and feasibility of ADP in preterm infants, (2) identify published clinical protocols, and (3) implement and assess a standardized routine—the Bavarian Clinical Protocol (BCP). Methods: We conducted two systematic literature reviews: one on the eligibility-to-assessment rate and safety of ADP in research contexts, and a second focusing on existing clinical protocols. In addition, we retrospectively analyzed routine ADP assessments at the NICU of Nuremberg Children’s University Hospital from January 2022 to December 2024, where the BCP had been introduced. Results: The literature review included 76 studies reporting a total of 8,317 assessments without adverse events. In experimental settings, the eligibility-to-assessment rate was 41%. We identified three published clinical protocols. Following BCP implementation, 626 of 702 eligible infants (89.1%) underwent a total of 851 ADP measurements. No adverse events were observed, and repeated assessments were integrated smoothly into clinical workflows. Conclusions: ADP can be safely and effectively incorporated into neonatal routine care. The Bavarian Clinical Protocol provides a practical framework for standardized application, improves comparability across centers, and supports the clinical use of body composition data to inform individualized nutritional strategies.

Mother’s own milk (MOM) offers the highest protection for preterm and low birth weight infants. However, breastfeeding can be challenging during neonatal hospitalization. When MOM is unavailable, donor human milk (DHM) is the recommended alternative for feeding vulnerable neonates. Human milk banks (HMBs) collect, process, and deliver DHM, playing a key role in lactation support and promoting MOM availability. Although HMBs are expanding globally, scale-up remains hindered, restricting equitable DHM access. In Switzerland, despite the existence of eight HMBs, the western region lacked such a facility until 2022. To address this gap, an interdisciplinary team from the Lausanne University Hospital (CHUV) and the Swiss Red Cross Interregional Blood Transfusion Centre (TIR) collaborated to establish a regional HMB. This partnership leveraged both institutions’ available expertise, infrastructure, and resources. After two years of preparation, the CHUV Lactarium launched in 2022 with the support of the Department of Health and Social Action (DSAS) of the Canton of Vaud. This novel human milk bank–blood bank model is fully integrated into the hospital’s neonatal care, nutrition, and breastfeeding programs, operating under a strict quality and coordination system. Since its implementation, the HMB has met 100% of DHM needs, with an 80% breastfeeding bridging rate. It has had a positive impact on neonatal care, family engagement, professional interest, and community awareness of human milk. This case study illustrates how synergistic collaboration can help bridge gaps in establishing a safe, efficient, and equitable HMB model. It also offers a scalable framework adaptable to other settings. Full article

Background/Objectives: Preterm infants are at high risk of extrauterine growth restriction and suboptimal neurological development due to cumulative nutrient deficits. Standard fortification (SF) of human milk does not account for individual macronutrient variability, potentially leading to inadequate intake. Target fortification (TFO) adjusts supplementation based on the measured macronutrient content, aimed at providing macronutrient intake aligned with ESPGHAN (European Society for Paediatric Gastroenterology, Hepatology and Nutrition) recommendations and optimize growth and development. This study aims to evaluate the effects of TFO compared to SF on growth, body composition, and neurological outcomes at 18 months corrected age. Methods: In this double-blind, randomized controlled trial, preterm infants (<30 weeks gestation) received either SF or TFO for at least three weeks. Macronutrient levels in breast milk were analyzed three times per week, with modular adjustments in the TFO group. Growth parameters, body composition at 36 weeks postmenstrual age, and Bayley Scales of Infant and Toddler Development III (BSID-III) scores at 18 months corrected age were assessed (n = 69). Results: TFO significantly increased protein, fat, and carbohydrate intake compared to SF, leading to higher weight gain (2514 ± 289 g vs. 2283 ± 332 g, p < 0.01) and growth velocity (21.7 ± 2.3 g/kg/d vs. 19.2 ± 2.2 g/kg/d, p < 0.001). In infants whose mother’s milk had low protein levels, fat-free mass was significantly higher with TFO compared to SF. BSID-III scores were higher in the TFO group across cognitive, language, and motor domains, with significant improvements in expressive language scores in infants whose mother’s milk had high protein levels (p < 0.05). The number of preterm infants with a motor BSID-III score of ≤70 was significantly lower in the TFO group compared to the SF group (0 vs. 3, p < 0.05). Conclusions: TFO enhanced growth and body composition and may support better neurological outcomes in preterm infants. While most BSID-III differences were not statistically significant, the data suggest that TFO may reduce the risk of developmental delays. Larger, multicenter trials are needed to confirm these findings. Full article

Background: Sufficient choline supply is essential for tissue functions via phosphatidylcholine and sphingomyelin within membranes and secretions like bile, lipoproteins and surfactant, and in one-carbon metabolism via betaine. Choline requirements are linked to age and genetics, folate and cobalamin via betaine, and arachidonic (ARA) and docosahexaenoic (DHA) acid transport via the phosphatidylcholine moiety of lipoproteins. Groups at risk of choline deficiency include preterm infants, children with cystic fibrosis (CF) and patients dependent on parenteral nutrition. Fortifiers, formula and supplements may differently impact their choline supply. Objective: To evaluate added amounts of choline, folate, cobalamin, ARA and DHA in fortifiers, supplements and formula used in pediatric care from product files. Methods: Nutrient contents from commonly used products, categorized by age and patient groups, were obtained from public sources. Data are shown as medians and interquartile ranges. Results: 105 nutritional products including fortifiers, formula and products for special indications were analyzed. Choline concentrations were comparable in preterm and term infant formulas (≤6 months) (31.9 [27.6–33.3] vs. 33.3 [30.8–35.2] mg/100 kcal). Products for toddlers, and patients with CF, kidney or Crohn’s disease showed Choline levels from 0 to 39 mg/100 kcal. Several products contain milk components and lecithin-based emulsifiers potentially increasing choline content beyond indicated amounts. Conclusions: Choline addition is standardized in formula for term and preterm infants up to 6 months, but not in other products. Choline content may be higher in several products due to non-declared sources. The potential impact of insufficient choline supply in patients at risk for choline deficiency suggests the need for biochemical analysis of products. Full article

Background/Objectives: Multi-lumen devices that limit physicochemical incompatibilities (PCIs) are frequently used in neonatal intensive care units where premature infants receive numerous infusions. The aim of the study was to investigate a PCI that occurred despite the use of a device of this type (EDELVAISS^® Multiline NEO, Doran International, Toussieu, France). Case Summary: A 7-week-old preterm infant received ganciclovir at therapeutic dosage for cytomegalovirus (CMV) infection. After the fifth administration of ganciclovir, a PCI occurred, leading to a white precipitate. The peripheral inserted central catheter (PICC) (PREMICATH^®2Fr, Vygon, Ecouen, France) had to be replaced. Laboratory reproduction of the administrations during 72 h, nuclear magnetic resonance (NMR) analysis and particle counting were carried out to analyse the occurrence of events leading to PCIs. The precipitate was linked to a PCI of parenteral nutrition associated with a dilution error of ganciclovir (omission of a 10-fold dilution step, resulting in ganciclovir being administered at 30 mg/L instead of 3 mg/L). Due to the presence of lipids in the parenteral nutrition, visual detection of the white precipitate was difficult. Conclusions: Multi-lumen infusion devices limit but do not prevent the occurrence of PCIs, particularly in the event of a preparation error. Despite the use of this type of device, great vigilance is still required, particularly with regard to prescription analysis and reconstitution procedures. Full article

Background: Human milk (HM) offers critical short- and long-term benefits for preterm and very low birth weight (VLBW) infants. In 2021, a human milk bank (HMB) was established at the IRCCS Giannina Gaslini Institute, aiming to improve HM feeding rates in this vulnerable population. Methods: We retrospectively analyzed feeding data from 442 VLBW infants (BW < 1500 g) admitted between 2018 and 2024. Data were drawn from the Vermont Oxford Network and Italian Neonatal Network registries. Feeding modalities—exclusive HM, infant formula milk (IM), and mixed feeding (MF)—were recorded and analyzed before and after HMB introduction. Results: Before 2021, MF was predominant, with exclusive HM rates below 10%. Following HMB implementation, exclusive HM feeding increased significantly, reaching 47.2% in 2024 (p < 0.0001). Regression analysis showed a positive trend for HM (+4.84%/year, p = 0.05), and a declining trend for IM (−1.96%/year) and MF (−2.88%/year). Projections suggest HM rates may exceed 58% by 2030. Conclusions: The introduction of the HMB was associated with a significant shift in feeding practices, increasing HM use and reducing IM exposure among VLBW infants. These findings underscore the importance of institutional strategies such as donor milk availability, lactation support, and maternal education in optimizing neonatal nutrition. Ongoing efforts are essential to sustain and extend these improvements beyond NICU discharge, ensuring the long-term benefits of human milk for preterm infants. Full article

Background/Objectives: Preterm neonates receiving parenteral nutrition (PN) are at risk of developing refeeding syndrome (RS). Risk factors and the related consequences remain largely undefined. In particular, the reason why only some preterm neonates out of a group receiving the same nutritional protocol will develop RS is yet to be fully understood. The aims of this study were to explore the clinical and nutritional factors contributing to RS and to assess the clinical consequences of this condition. Methods: A retrospective study was conducted, including all newborns with gestational age ≤ 34 weeks and/or body birth weight ≤ 1500 g who were consecutively admitted to the neonatal intensive care unit (NICU) of “Umberto I” Hospital, Sapienza University of Rome, from 2015 to 2022. The population was divided into two groups comprising newborns who developed RS (cases) and infants who did not develop the condition (controls) up to the first 2 weeks of life. The enrolled newborns were compared for clinical and nutritional factors and main morbidities. Results: A total of 412 neonates were enrolled, consisting of 53 cases and 359 controls. The main prenatal risk factor for RS was found to be fetal distress (p = 0.028). The occurrence of RS was identified as statistically significantly associated (p = 0.010; p = 0.007) with the development of extrauterine growth restriction (EUGR) and retinopathy of prematurity (ROP). Conclusions: Fetal distress is the predominant perinatal risk factor associated with the development of RS in preterm neonates managed with early currently recommended PN. These findings suggest an increased risk of ROP and EUGR in preterm neonates with RS. Full article
