Purpose: Our understanding of the influence of preterm birth and related perinatal exposures on early brain development is limited, hampering personalized optimization of neuroprotective strategies. This study assesses the effect of gestational age (GA) at birth on brain volumes at term-equivalent age (TEA) in infants without overt brain injury born across the GA spectrum. Methods: A cohort of infants born across the GA spectrum (25–40 weeks’ gestation) underwent 3T brain MRI around TEA (40–46 weeks postmenstrual age). Eight brain regions, intracranial and total tissue volumes were segmented using MANTiS (morphologically adaptive neonatal tissue segmentation toolbox). Segmentations were visually quality-checked and excluded if segmentation failed. Absolute TEA volume in relation to GA was assessed using univariate and multivariate (correction for postmenstrual age) linear regression analysis. Statistical significance was set at p < 0.05. Post hoc scatter plots of brain volumes relative to intracranial volumes were created. Results: Fifty infants were included (mean GA = 35.0 [SD = 3.3, range = 25.7–40.1] weeks). A higher GA at birth was significantly related to lower cerebrospinal fluid (p = 0.004) and amygdala (p = 0.02) volumes; no significant relation was found between GA and other volumes. Post hoc analyses showed positive trends between GA and several brain structures, including total brain tissue, cortical gray matter, deep gray matter, hippocampus, cerebellum and brainstem volumes. Conclusions: Our results suggest that GA has an effect on TEA brain volumes that is independent of brain lesions, with lower GA being associated with smaller brain tissue volumes and significantly larger cerebrospinal fluid volume. Preterm birth and related exposures may thus affect early brain growth and contribute to neurodevelopmental challenges encountered by preterm-born children. 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: Preterm infants and their families face a challenging experience during their stay in the neonatal intensive care unit (NICU). Family-centered care emphasizes the importance of welcoming parents, involving them in their baby’s daily care, and supporting the development of parenting skills. NICU staff should support parents in understanding their baby’s needs and in strengthening the parent–infant bond. Although many tools outline what parents should learn, there is a limited structured framework to monitor their involvement in the infant’s care. Tracking parental participation in daily caregiving activities could support professionals in effectively guiding families, ensuring a smoother transition to discharge. Aims: The aim of this study was to evaluate the adherence to and effectiveness of a structured tool for parental involvement in the NICU. This tool serves several key purposes: to track the progression and timing of parents’ autonomy in caring for their baby, to support parents in building caregiving competencies before discharge, and to standardize the approach of NICU professionals in promoting both infant care and family engagement. Methods: A structured template form for documenting parental involvement (“together TO-CARE template”, TTCT) was integrated into the computerized chart adopted in the NICU of Modena. Nurses were asked to complete the TTCT at each shift. The template included the following assessment items: parental presence; type of contact with the baby (touch; voice; skin-to-skin); parental involvement in care activities (diaper changing; gavage feeding; bottle feeding; breast feeding); and level of autonomy in care (observer; supported by nurse; autonomous). We evaluated TTCT uploaded data for very low birth weight (VLBW) preterm infants admitted in the Modena NICU between 1 January 2023 and 31 December 2024. Staff compliance in filling out the TTCT was assessed. The timing at which parents achieved autonomy in different care tasks was also measured. Results: The TTCT was completed with an average of one entry per day, during the NICU stay. Parents reached full autonomy in diaper changing at a mean of 21.1 ± 15.3 days and in bottle feeding at a mean of 48.0 ± 22.4 days after admission. The mean length of hospitalization was 53 ± 38 days. Conclusions: The adoption of the TTCT in the NICU is feasible and should become a central component of care for preterm infants. It promotes family-centered care by addressing the needs of both the baby and the family. Encouraging early and progressive parental involvement enhances parenting skills, builds confidence, and may help reduce post-discharge complications and readmissions. Furthermore, the use of a standardized template aims to foster consistency among NICU staff, reduce disparities in care delivery, and strengthen the support provided to families of preterm infants.

Background: Extremely premature neonates are at increased risk for respiratory complications, often resulting in recurrent hospitalizations during early childhood. Early identification of preterm infants at highest risk of respiratory hospitalizations could enable targeted preventive interventions. While clinical and demographic factors offer some prognostic value, integrating transcriptomic data may improve predictive accuracy. Objective: To determine whether early-life gene expression profiles can predict respiratory-related hospitalizations within the first four years of life in extremely preterm neonates. Methods: We conducted a retrospective cohort study of 58 neonates born at <32 weeks’ gestational age, using publicly available transcriptomic data from peripheral blood samples collected on days 5, 14, and 28 of life. Random forest models were trained to predict unplanned respiratory readmissions. Model performance was evaluated using sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUC). Results: All three models, built using transcriptomic data from days 5, 14, and 28, demonstrated strong predictive performance (AUC = 0.90), though confidence intervals were wide due to small sample size. We identified 31 genes and eight biological pathways that were differentially expressed between preterm neonates with and without subsequent respiratory readmissions. Conclusions: Transcriptomic data from the neonatal period, combined with machine learning, accurately predicted respiratory-related rehospitalizations in extremely preterm neonates. The identified gene signatures offer insight into early biological disruptions that may predispose preterm neonates to chronic respiratory morbidity. Validation in larger, diverse cohorts is needed to support clinical translation. Full article

Background: Very preterm infants are at increased risk of impairment. The objective was to explore the effect of immediate parent–infant skin-to-skin contact at very preterm birth on cognition, motor, social, and language development during the two first years. Methods: The Immediate Parent-Infant Skin-To-Skin Study (IPISTOSS) was a clinical trial with inclusions between April 2018 to June 2021, in three Scandinavian neonatal intensive care units. Infants were randomised at gestational age 28 + 0 to 32 + 6 weeks plus days, to immediate and continuous skin-to-skin contact at birth or conventional care, during the first six hours of life. Results: At three months, 42 infants underwent a General Movement Assessment. At four and 12 months, 69 and 62 infants, respectively, were assessed with the Alberta Motor Infant Scale. At 24 months, language and cognition were tested in 62 infants with the Bayley Scales of Infant and Toddler Development, third edition. Parents completed the Modified Checklist for Autism in Toddlers for 57 infants. There were no significant differences in motor development, cognition, or autism spectrum disorders. A significant difference in language scores in favour of immediate skin-to-skin contact, was found, when adjusted for fathers’ education, mothers’ education, and infants’ sex, Beta (95% CI): 32.00 (7.57, 56.43) p = 0.01, 11.51 (8.94, 55.06) p = 0.007, and 32.00 (7.85, 56.15) p = 0.01, respectively. Conclusions: Skin-to-skin contact immediately at birth did not enhance cognition, motor, or social development during the first two years of life but may have been important for language skills. Our findings support the World Health Organisation guidelines recommending iSSC for preterm born infants in all settings. Full article

Background and objectives: Neurosurgical intervention on the newborn’s developing brain is a risk factor for neurodevelopmental disorders (NDDs). These patients necessarily require regular, coordinated follow-up. The ventricular subgaleal shunt (VSGS) technique has been used since 2013 at Rouen University Hospital. Like any change in practice, this technique must be evaluated. In this paper, we describe the population of patients with hydrocephalus treated by VSGS, the complications associated with the procedure, and the outcome of these patients at two and six years old. Methods: This study was an observational, descriptive, retrospective, single-center study. Children included were those less than three months old with hydrocephalus treated by VSGS at Rouen University Hospital from January 2013 to December 2023. Data were anonymized and collected using EDSaN software. A descriptive analysis was performed. Results: Thirty-two patients were included in our study. Of these, 22 (69%) were born prematurely; 16 (50%) of these 22 had postnatal intraventricular hemorrhage (IVH) requiring treatment with VSGS. A total of three patients (13.6%) died within the first year of life; twenty-four patients (75%) required definitive shunting. Twenty-two patients were over 2 years old in our study. Only 10 of them acquired the ability to walk (45%). Cerebral palsy was present in 10 (45%) patients. Fifteen patients were over 6 years old; thirteen (87%) attended school, but six (40%) had special needs (the need of an assistant, or part-time schedule). In our study, only 24 patients (82%) were followed by a pediatrician trained in neurodevelopment at Rouen University Hospital, and 27 (93%) were followed by a neurosurgeon. Conclusions: This study describes all patients with hydrocephalus treated by VSGS at Rouen University Hospital between January 2013 and December 2023, as well as their complications and their neurological outcomes. The follow-up of these children at risk of NDDs is essential. Full article

Background/Objectives: Neonatal pain must be treated due to its potential short- and long-term adverse effects. A frenotomy is a painful procedure where common strategies to relieve pain (oral sucrose solutions and sucking) cannot be used because the technique is performed on the tongue. Lavender essential oil (LEO) is useful in treating pain during blood sampling, heel punctures, vaccination, and frenotomies. We aimed to determine whether smelling colostrum had similar effects as inhaled LEO during frenotomies. Methods: A prospective, randomized clinical trial was carried out with neonates who underwent a frenotomy for ankyloglossia between September 2023 and June 2024. We assessed pain using the NIPS score, heart rate, oxygen saturation, and crying time. After obtaining parental informed consent, we randomized patients into experimental and control groups. In both groups, we performed swaddling, administered 1 mL of oral sucrose, and let the newborn suck for 2 min. In the experimental group, we placed a gauze pad with two drops of colostrum, whereas in the control group, we used one drop of LEO 2 cm under the neonate’s nose prior to and during the frenotomy. Results: We enrolled 142 patients (71 experimental cases and 71 controls). The experimental group showed lower crying times (28.0 vs. 40.2 s, p = 0.03). Both groups showed similar NIPS scores (1.4 vs. 1.5, p = 0.28). We observed no side effects in either of the groups. Conclusions: Inhaled colostrum and LEO help relieve pain in neonates who undergo a frenotomy for ankyloglossia and have no side effects. Aromatherapy with colostrum may decrease crying time during the frenotomy. Full article

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: Frenotomy is the procedure of choice for treating ankyloglossia. The literature reports that readhesion of the frenulum occurs in 2.6–13% of cases. There is no published evidence to support performing tongue exercises to prevent it. We aimed to determine the readhesion rate of ankyloglossia, the benefits of tongue exercises to prevent it, and the characteristics of patients who experienced readhesion. Methods: This is a prospective, observational study of neonates who underwent a frenotomy between January and August 2024. Following the frenotomy, we recommended that all parents perform a series of exercises 6–8 times daily over 15 days. Patients were re-evaluated 10–15 days post-procedure for signs of ankyloglossia using the Hazelbaker tool and clinical variables such as nipple pain or cracks. Results: We enrolled 212 patients; thirty patients underwent a refrenotomy (14.1%). The raw risk of readhesion in our study was 0.335 (95%CI 0.275–0.401), and for symptomatic readhesion, 0.156 (95%CI 0.113–0.211). Adjusted by sex, the risk of readhesion for female patients was 0.236 (95%CI 0.155–0.344), and for males, 0.390 (95%CI 0.312–0.474). The appearance and function Hazelbaker scores were significantly lower before the frenotomy than post-procedure in all cases. In females, not following the exercise protocol multiplied the risk of readhesion by 1.61 (95%CI 1.03–2.56), whereas in males the risk was multiplied by 1.47 (95%CI 1.03–2.08). Symptomatic readhesion was significantly correlated with age at frenotomy and Hazelbaker score. Conclusions: Readhesion of tongue-tie was higher than previously published (33.5%); however, symptomatic readhesion was less frequent (15.6%). Proper adherence to post-frenotomy exercises significantly reduces the risk of readhesion, although it has less impact on symptomatic readhesion. Full article

Background/Objectives: Cesarean delivery often leads to delayed breastfeeding initiation, potentially affecting infant health compared with vaginal delivery. This prospective observational study (conducted between August 2022 and January 2024) comparatively evaluates the impact of delivery method—vaginal, planned cesarean, and emergency cesarean—on breastfeeding initiation and continuation and examines the maternal factors influencing these outcomes. Materials and Methods: We enrolled 338 mother–infant pairs at a tertiary university hospital. Breastfeeding effectiveness was assessed using the Bristol Breastfeeding Assessment Tool (BBAT) at birth and at one, three, and six months postpartum. Rates of breastfeeding continuation and formula supplementation were documented through structured interviews. Results: The mothers who delivered vaginally had a significantly higher rate of breastfeeding within one hour after birth (85.5%) compared with planned (57.9%) and emergency cesarean sections (64.9%) (p < 0.001). Baseline BBAT scores were higher for vaginal births but converged across the groups by one month postpartum (p > 0.05). At six months, breastfeeding continuation rates remained high (94.4–95.2%) irrespective of delivery method. Conclusions: Delivery method exerts a transient effect on breastfeeding initiation. With lactation support, the mothers delivering by cesarean section achieved comparable breastfeeding outcomes within the first month postpartum. These findings reinforce the importance of Baby-Friendly Hospital Initiative (BFHI) practices, including immediate skin-to-skin contact, effective pain management, and lactation counseling, in ensuring equitable breastfeeding outcomes.

Background/Objectives: Platelet transfusions are administered to preterm neonates with thrombocytopenia prophylactically to decrease their bleeding risk. The amplitude difference between the extrinsic rotational thromboelastometry (EXTEM) and the fibrinogen rotational thromboelastometry (FIBTEM) assays is considered an index of platelet contribution to clot strength, guiding transfusion management. The difference in maximum clot elasticity (MCE) (namely the platelet contribution to clot elasticity—MCEplatelet) is considered highly accurate. Limited data exist to specify the contribution of platelets and fibrinogen in clot formation during sepsis in neonates with thrombocytopenia. We investigated the potential of MCFplatelet (platelet contribution to clot firmness) and MCEplatelet in reflecting platelet count and function in septic preterm neonates. We simultaneously assessed the contribution of both platelets and fibrinogen to clot strength during sepsis. Methods: We compared 28 preterm neonates with sepsis born (gestational age 24⁺¹-34⁺³) with 30 healthy counterparts by using rotational thromboelastometry (ROTEM) and platelet flow cytometry. Results: MCEplatelet showed a higher association with platelet count in the sepsis group than MCFplatelet (R² = 47.66% vs. R² = 18.79%). MCEplatelet (AUC = 0.81) had better discrimination capability than MCFplatelet (AUC = 0.78) in platelet count <100 × 10³/L. MCEplatelet was poorly associated with platelet function. The contribution of platelets was significantly lower (MCEplatelet = 84.03 vs. 89.21; p < 0.001) compared with fibrinogen (36.9 vs. 25.92; p < 0.001) in the sepsis group. Conclusions: MCEplatelet has a better predictive value than MCFplatelet. In clinical practice, the elasticity difference between EXTEM and FIBTEM may replace the amplitude difference. The higher contribution of fibrinogen in clot strength during neonatal sepsis results in higher MCF, even in neonates with thrombocytopenia. Full article

Background: Early and accurate diagnosis of neonatal sepsis remains a clinical challenge due to nonspecific signs and limitations of conventional biomarkers. The immature platelet fraction (IPF), a novel hematologic parameter reflecting thrombopoietic activity, has emerged as a potential early sepsis indicator. This study aimed to evaluate the diagnostic value of IPF in neonatal sepsis prior to the onset of thrombocytopenia. Methods: This prospective study enrolled neonates with early-onset sepsis (EOS), late-onset sepsis (LOS), and healthy controls. IPF, C-reactive protein (CRP), procalcitonin (PCT), and hematologic indices were measured at diagnosis and 48–72 h post-treatment. Diagnostic performance was evaluated via ROC curve analysis, and correlations between IPF and inflammatory/hematologic markers were examined. IPF levels were also compared based on blood culture results. Results: IPF levels were significantly higher in both EOS (n: 56) and LOS (n: 50) groups compared to controls (n: 44) (p < 0.001). ROC analysis showed excellent diagnostic performance, with AUCs of 0.98 (EOS) and 0.99 (LOS). Following antibiotic treatment, IPF levels declined significantly (p < 0.001), supporting its dynamic value. Strong and moderate correlations were found with MPV and CRP, respectively, and an inverse association with platelet count, but not with PCT. Moreover, IPF levels were higher in culture-positive cases compared to culture-negative ones (13.1% vs. 9.8%; p = 0.017) and exhibited diagnostic performance comparable to CRP in predicting blood culture positivity. Conclusions: This study presents original and clinically relevant data supporting IPF as a promising and practical hematologic biomarker for early detection and treatment monitoring of neonatal sepsis. Its integration into standard sepsis evaluation protocols may improve early risk stratification and clinical decision-making in neonatal intensive care settings. Full article

Objective: The aim of this study was to describe the presenting characteristics and outcomes of neonates with respiratory failure referred for extracorporeal membrane oxygenation (ECMO) support, compare those who received ECMO support (ECMO group) to those who did not (non-ECMO group), and evaluate the predictive variables requiring ECMO support. Methods: All neonates (<15 days) with respiratory failure (without congenital diaphragmatic hernia or congenital heart disease) referred to our regional ECMO center from 2014 to 2023 were included in this retrospective study. Patient demographics, birth history, and clinical and outcome variables were analyzed. Oxygenation indices and vasoactive–inotropic scores obtained at PICU arrival and four hours after arrival were compared between the two groups using ROC analysis, with ECMO initiation as an outcome variable. Youden’s index was used for optimal threshold values. Chi-square, Mann–Whitney U, and binary logistic regression were used for comparative analyses. Results: Out of the 147 neonates, 96 (65%) required ECMO support. The two groups significantly differed in the prevalence of pulmonary hypertension (pHTN; systemic or suprasystemic pulmonary pressures), lactate level, and oxygenation indices. Mortality was not different between the two groups. Presence of oxygen saturation index (OSI) ≥ 10 had a sensitivity 96.8% in predicting the need for ECMO support. On regression analysis, OSI and pHTN were independent predictors of ECMO support. Conclusions: Oxygenation indices and echo findings predict the need for ECMO support in neonatal hypoxemic respiratory failure. These findings help non-ECMO centers make appropriate and timely transfers of neonates with respiratory failure to ECMO centers. Full article

Background/Objectives: Although there is a critical need for timely, accurate recognition of infants with hypoxic ischemic encephalopathy (HIE) eligible for therapeutic hypothermia (TH), there is little published literature that comprehensively validates strategies to achieve this. For the Mater Mothers’ Hospital, a screening protocol combining use of umbilical cord gases according to obstetric criteria and other evidence of depression at birth with a decision aid (the HIE Trigger Tool (TT)) for at-risk infants was developed. We audited whether the protocol supported appropriate clinical decisions. Methods: Obstetric records were searched from 1 January 2016 to 31 July 2022 for eligible infants. Neonatal records were examined to assess usage, determine outcomes (diagnosis of HIE or other neurological conditions, use of TH, mortality and neurodevelopmental outcomes) and detect any additional HIE cases. Results: Of 64,055 live births ≥35 weeks, 35.4% had cord gases taken. Of 580 eligible infants, the TT was applied to 498 (86.3%), 155 of whom screened positive for HIE (any severity). Of 76 infants with moderate or severe encephalopathy, 69 received TH. The other seven had contraindications to TH (n = 2), late presentations without any depression at birth (>6 h, n = 3) or other causes of their encephalopathy (n = 2). The TT (which per instructions was commenced by one hour of age) was used to identify 61 of the infants with moderate/severe encephalopathy, while 15 were diagnosed before it was applied. No infants who screened negative using the TT presented later with seizures or any other signs of moderate or severe HIE. Conclusions: The protocol including cord gases and the HIE TT is an effective method of screening for acute HIE needing TH. Full article

Background/Objectives: Continuous renal replacement therapy (CRRT) is an important treatment method that is becoming a commonly-used procedure in neonatal intensive care units (NICUs), especially in critically-ill neonates. Methods: We conducted a retrospective study aimed to evaluate factors influencing the outcomes of CRRT in neonates and preterm infants. The study analyzed data from 41 newborns treated with CRRT at our NICU over a ten-year period. Demographic, clinical, and laboratory parameters were assessed, including gestational age, birth weight, PRISM III score, and laboratory markers like urea, creatinine, and potassium levels, as well as characteristics of CRRT. Results: Our research found that the duration of CRRT, the presence of anuria, and higher potassium levels after initiation of CRRT were significant predictors of a poor outcome. Despite the lack of significant correlation between demographic characteristics, PRISM III score and the outcome, our findings highlight the importance of timely CRRT initiation and efficient management to improve survival. Conclusions: Our study identified several significant prognostic indicators in neonates undergoing renal replacement therapy. While these findings provide valuable insights, further research is needed to establish clear theoretical guidelines and improve clinical decision-making. Full article
