This study aimed to evaluate the impact of in situ simulation-based training on quality indicators of patient care at a level IV neonatal intensive care unit. A before-and-after, non-controlled quality improvement study was performed at the Division of Neonatology, Medical University of Graz. The educational intervention comprised a period of 4 months, with structured in situ simulation training delivered regularly for neonatal providers and nurses in interprofessional teams. The primary study outcome was the quality of non-technical skills and team interaction during actual postnatal stabilization and resuscitation. This was assessed using video recording during two 2-month observational phases before (pre-training) and after the educational intervention (post-training). Delivery room video recordings were assessed by two external, blinded neonatologists using the Anaesthetists' Non-Technical Skills (ANTS) score. Furthermore, we collected clinical patient data from video-recorded neonates during the pre- and post-training periods, and training participants' individual knowledge of neonatal resuscitation guidelines was assessed using a before- and after-questionnaire. A total of 48 healthcare professionals participated in 41 in situ simulation trainings. The level of non-technical skills and team interaction was already high in the pre-training period, and it did not further improve afterwards. Nonetheless, we observed a significant increase in the teamwork event "evaluation of plans" (0.5 [IQR 0.0-1.0] versus 1.0 [1.0-2.0], p = 0.049). Following the educational intervention, training participants' knowledge of neonatal resuscitation guidelines significantly improved, although there were no differences in secondary clinical outcome parameters., Conclusion: We have successfully implemented a neonatal in situ simulation training programme. The observed improvement in one teamwork event category in the post-training period demonstrates the effectiveness of the training curriculum, while also showing the potential of in situ simulation training for improving postnatal care and, ultimately, patient outcome., What Is Known: • In situ simulation-based training is conducted in the real healthcare environment, thus promoting experiential learning which is closely aligned with providers' actual work. • In situ simulation-based training may offer an additional benefit for patient outcomes in comparison to other instructional methodologies., What Is New: • This observational study investigated translational patient outcomes in preterm neonates before and after delivery of high-frequency in situ simulation-based training at a level IV neonatal intensive care unit. • There was a significant increase in the frequency of one major teamwork event following the delivery of in situ simulation-based training, indicating a notable improvement in the non-technical skills domain, which is closely linked to actual team performance., (© 2024.

Background: Migraine prevalence has been estimated to be as high as 25% during reproductive years. Despite this, and the known significantly lower odds of acute stroke being correctly diagnosed among women versus men, little is known about the migraine-stroke connection in this vulnerable population. Our study seeks to provide a consolidated examination of cerebrovascular and obstetric complications of migraines in pregnant women and to evaluate the role of concurrent comorbidities. Methods: We utilized the 2016-2020 Healthcare Cost and Utilization Project's National Inpatient Sample with the International Classification of Diseases, 10th Revision diagnostic codes to compare pregnant patients with migraines with those without migraines. Multivariable logistic regression was used to examine the incidence of subtypes of stroke while controlling for confounding variables. Results: Overall, 19,825,525 pregnant patients were evaluated; 219,175 (1.1%) had a concomitant diagnosis of migraine. Pregnant patients with migraines were more likely to suffer ischemic (0.1% versus 0.0%) or hemorrhagic stroke (0.3% versus 0.1%). On multivariate analysis, acute ischemic stroke was most strongly associated with migraine with aura (odds ratio [OR], 23.26; 95% confidence interval [CI], 18.46-29.31), followed by migraine without aura (OR, 8.15; 95% CI, 4.79-13.88). Conclusions: Pregnant women with migraine are at a significantly increased risk for both ischemic and hemorrhagic stroke. Pregnant women with migraines should be cautioned that they may be at an increased risk of stroke, particularly if they are experiencing an aura, and encouraged to contact their medical providers to rule out neurological complications.

The development of fetal organs can be impacted by systemic changes in maternal circulation, with the placenta playing a pivotal role in maintaining pregnancy homeostasis and nutrient exchange. In clinical obstetrics, oxytocin (OXT) is commonly used to induce labor. To explore the potential role of OXT in the placental homeostasis of OXT, we compared OXT levels in neonatal cord blood among neonates (23-42 weeks gestation) whose mothers either received prenatal OXT or experienced spontaneous labor. Our previous research revealed that the oxytocin receptor (OXTR), essential in forming the blood-retina barrier, is expressed in the retinal pigment epithelium (RPE). We hypothesized that perinatal OXT administration might influence the development of the neural retina and its vasculature, offering therapeutic potential for retinal diseases such as retinopathy of prematurity (ROP). Plasma OXT levels were measured using a commercial OXT ELISA kit. Human fetal RPE (hfRPE) cells treated with OXT (10 µM) were assessed for gene expression via RNA sequencing, revealing 14 downregulated and 32 upregulated genes. To validate these differentially expressed genes (DEGs), hfRPE cells were exposed to OXT (0.01, 0.1, 1, or 10 µM) for 12 h, followed by RNA analysis via real-time PCR. Functional, enrichment, and network analyses (Gene Ontology term, FunRich, Cytoscape) were performed to predict the affected pathways. This translational study suggests that OXT likely crosses the placenta, altering fetal OXT concentrations. RNA sequencing identified 46 DEGs involved in vital metabolic and signaling pathways and critical cellular components. Our results indicate that the perinatal administration of OXT may affect neural retina and retinal vessel development, making OXT a potential therapeutic option for developmental eye diseases, including ROP.

Preterm infants are most at risk of iron deficiency. However, our knowledge of the regulation of iron homeostasis in preterm infants is poor. The main goal of our research was to develop and validate an animal model of human prematurity to assess iron status in preterm infants. We performed a cesarean section on sows on the 109th day of pregnancy, which corresponds to the last trimester of human pregnancy. Preterm piglets showed decreased body weight, red blood cell indices, plasma iron level and transferrin saturation. Interestingly, higher hepatic and splenic non-heme iron content and plasma and hepatic ferritin levels were found in premature piglets compared with term ones. In addition, premature piglets showed higher mRNA levels of iron-regulatory hormone hepcidin in the liver than term animals, which have not been reflected in higher plasma hepcidin-25 levels. We also showed changes in hepcidin regulators, including hepatic bone morphogenetic protein 6, plasma erythroferrone and growth differentiation factor 15 in preterm piglets. Consequently, no difference was observed in iron-exporter ferroportin levels in the spleen and liver. Overall, it seems that premature piglets show a pattern of iron metabolism characteristic of functional iron deficiency and iron accumulation in the tissue.

Purpose: To determine the pattern, degree and prevalence of optic disc optical coherence tomography (OCT) alterations in adults born preterm with very low birth weight (VLBW; birth weight < 1500 g)., Methods: Optic disc OCT was assessed in 98 VLBW participants and 139 term-born controls from birth cohorts in Finland and Norway at the mean age of 36 years. The participants had not been treated for retinopathy of prematurity and had no diagnosed brain abnormality. OCT assessment included parameters for optic disc size, neural rim and peripapillary retinal nerve fibre layer thickness (pRNFLT), and for the foveal developmental stage. Background data, visual acuity, refractive error and intraocular pressure were recorded., Results: In the VLBW group, optic disc neural rim and pRNFLT were significantly decreased, most frequently in the nasal and inferior sectors. In 40% (95% CI: 33-47) of the VLBW eyes, nerve fibre thickness of at least one optic disc sector was below the fifth percentile of the control group, including 9% (95% CI: 6-14) subgroup falling below the first percentile, that is, clinically below normal limits. VLBW participants with nerve fibre thickness below the fifth percentile did not differ by perinatal data or foveal developmental stage from the other VLBW participants. All participants had normal visual acuity., Conclusion: A moderate decrease of the optic disc neural rim and pRNFLT is frequently seen in clinically healthy adults born preterm with VLBW. Awareness of the VLBW-related optic disc nerve fibre shallowness especially in the inferior and nasal sectors is important while evaluating acquired optic disc pathology in adulthood., (© 2024 The Author(s).

Aim: This research was conducted to evaluate the effects of Reiki and facilitated tucking position on pain, stress and physiologic parameters in preterm infants during orogastric tube (OGT) insertion., Methods: The study used a single-blind, parallel-group randomised controlled experimental design. It was carried out in the neonatal intensive care unit of a hospital in Niğde/Turkey between February 2022 and January 2023. A total of 45 preterm infants, who met the study criteria and whose sample size was determined according to power analysis, were randomly divided into three groups. As an intervention, the facilitated tucking position was applied to the first group, and Reiki was applied to the second group during OGT insertion. Routine application continued in the control group. The Infant Introductory Information Form, Physiological Parameter Follow-up Chart, Infant Stress Scale (ISS) and Premature Infant Pain Profile Scale-Revised (PIPP-R) were used for data collection. Significance was accepted as P < 0.05 in the statistical analysis., Results: It was determined that the infants were homogeneously distributed between the experimental and control groups (P > 0.05). Infants who received the facilitated tucking position and Reiki intervention had better physiological stability compared to the control group (P < 0.05). The group with the lowest average stress (1.53 ± 0.99) and pain scores (4.06 ± 1.22) during OGT insertion was the facilitated tucking group (P < 0.001). After the procedure, stress and pain scores in both the facilitated tucking group and the Reiki group were found to be significantly lower than those in the control group (P < 0.001)., Conclusions: The results of the study showed that the facilitated tucking position during OGT insertion was especially effective in reducing the pain and stress of infants. Both the facilitated tucking position and Reiki were determined to be effective interventions in reducing the pain and stress of infants more quickly after the procedure. The results of study contribute to the recommendation that NICU nurses should include non-pharmacological methods to decrease the pain of preterm infants during procedural pain., (© 2024 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Background: Cranial measurements are crucial for evaluating preterm general development because they are a surrogate tool for evaluating brain growth. Usually, they are based on tape-measured head circumference; however, a three-dimensional (3D) approach expands the diagnostic spectrum to the evaluation of cranial volume and shape., Aims: Very preterm (vPT) infants face multiple risks and obstacles in their early development. In this study, we analyze the risk for cranial anomalies of vPT compared with term-born (TB) infants during the first year of life., Study Design and Subjects: In this single-centre prospective cohort study, 23 vPT and 24 TB healthy infants were assessed. At term equivalent age (TEA) of vPT and time of birth of TB, and 1, 3, 6 and 12 months of postmenstrual age, respectively, a 3D head scan was performed and cephalometrically evaluated regarding cranial growth (head circumference, cranial volume) and shape., Results: Head circumference and cranial volume showed a similar course in vPT and TB. Cranial shape differed significantly between vPT and TB. At TEA, vPT showed longer and narrower heads (dolichocephaly), a difference that disappeared around the 6th month of life. Presence of plagiocephaly was initially similar in vPT and TB, with an increasing difference between both groups with a peak at six months when 34.8 % of the vPT versus none of the TB showed a moderate to severe plagiocephaly (p = 0.004). In vPT, cranial volume significantly correlated with cranial shape, whereas dolichocephaly at TEA had no influence on the further course of plagiocephaly., Conclusion: Cranial development of vPT follows a different course than of TB in terms of cranial shape anomalies, while cranial growth remains unaffected.

Objective: To investigate the rate of obstetric and perinatal outcomes of premature rupture of membranes (PROM) occurring before 26 weeks in twin pregnancies., Data Source: Medline, Embase, Cinahl and Web of Science databases were searched electronically up to January 2024., Study Eligibility Criteria: The selection criteria included both prospective and retrospective studies of twin pregnancies with PROM before 26 weeks of gestation. Case reports, case series with fewer than 5 cases, review articles, letters to the editor and editorials were excluded. Studies including both singletons and twin pregnancies were also excluded., Study Appraisal and Synthesis Method: We used meta-analyses of proportions to combine data and assess the pooled proportions. We used a random-effect model to perform the pooled data analyses. The study was registered with the PROSPERO database (CRD 42022368057). Quality assessment of the included studies was performed usingthe Newcastle-Ottawa Scale for cohort studies., Results: Eight studies including 227 twin pregnancies were included in the analysis. The pooled proportion of termination of pregnancy (TOP) was 4.6 % (95 % CI 1.5-13.4), while the rate of selective TOP (sTOP) was 24.5 % (95 % CI 7.1-57.7). After the exclusion of cases of TOP, the overall rate of spontaneous miscarriage or fetal demise was 20.9 % (95 % CI 11.1-35.8), whereas the live birth rate of at least one twin was 71.6 % (95 % CI 61.2-80.1) of the ongoing pregnancies. The mean gestational age at delivery was 26.5 (95 % CI 25.1-28.0) weeks and the mean latency between PROM and delivery was 5.4 weeks (95 % CI 4.8-5.9) in all cases including those with fetal deaths. Neonatal outcomes showed that the overall neonatal mortality was 26.4 % (95 % CI 16.7-39.2). When focusing only on pregnancies undergoing sTOP, the observed livebirth rate was 87.7 %. The gestational age at rupture of membranes in these cases was 16.8 (95 % CI 14.9-18.6) weeks and the latency between PROM and delivery was significantly longer (19.9 (95 % CI 18.0-21.7) weeks) than that observed in unterminated pregnancies, with a mean gestational age at delivery nearly in the range of term (36.9 weeks)., Conclusions: PROM in twins before 26 weeks is associated with overall high rates of adverse obstetric and neonatal outcomes, and it represents a clinical challenge for both counseling and management. Larger prospective studies unified objective protocols in terms of antenatal surveillance and management are needed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Objectives: This study aimed to assess the association between the quality of antenatal care (ANC) service utilisation and adverse birth outcomes among adolescent women in Sub-Saharan Africa (SSA)., Methods: A two-level mixed-effects model was employed using the recent Demographic Health Survey (DHS) data from 22 SSA countries. Both bivariable and multivariable multilevel analyses were conducted to assess the association between individual and community level factors with adverse birth outcomes. The results of the fixed effects model were interpreted in the form of adjusted odds ratios (AORs) with 95% confidence intervals (95% CIs)., Results: In SSA, 23.5 % of adolescent mothers experienced adverse birth outcomes. This study found that receiving high quality ANC was associated with a 28 % reduction in the likelihood of adverse birth outcomes (AOR = 0.72, 95 % CI: 0.63, 0.83). Among the individual-level factors, middle-aged adolescence (AOR = 1.23, 95 % CI: 1.11, 1.36), being a female newborn (AOR = 1.15, 95 % CI: 1.05, 1.26), single marital status (AOR = 0.87, 95 % CI: 0.78, 0.96) and higher educational status (AOR = 0.83, 95 % CI: 0.74, 0.93) were significantly associated with adverse birth outcomes. From the community-level variables, women from Eastern Africa had positive significant association with adverse birth outcomes (AOR = 1.30, 95 % CI: 1.15, 1.46)., Conclusions: Nearly one-fourth of adolescent women in SSA experienced at least one type of adverse birth outcome. Low quality of ANC was significantly associated with adverse birth outcomes. Policymakers need to consider a comprehensive, essential, and minimal package of ANC to enhance the quality of ANC, which is crucial for better adolescent birth outcomes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Moderate-late preterm-born infants experience more frequent and severe respiratory tract infections and wheezing compared to term-born infants. Decreasing the risk on respiratory tract infections and wheezing in this group is vital to improve quality of life and reduce medical consumption during infancy, but also to reduce the risk on asthma and COPD later in life. Until now, moderate-late preterm infants are underrepresented in research and mechanisms underlying their morbidity are largely unknown, although they represent 80% of all preterm-born infants. In order to protect these infants effectively, it is essential to understand the role of the immune system in early life respiratory health and to identify strategies to optimize immune development and respiratory health. This review elaborates on risk factors and preventative measures concerning respiratory tract infections and wheezing in preterm-born infants, exploring their impact on the immune system and microbiome. Factors discussed are early life antibiotic use, birth mode, feeding type and living environment. Further, differences in adaptive and innate immune maturation between term and preterm infants are discussed, as well as differences in local immune reactions in the lungs. Finally, preventative strategies are being explored, including microbiota transplantation, immune modulation (through pre-, pro-, syn- and postbiotics, bacterial lysates, vaccinations, and monoclonal antibodies) and antibiotic prophylaxis., (© 2024 The Author(s).

Background: Preterm birth is the leading cause of childhood mortality, and respiratory distress syndrome is the predominant cause of these deaths. Early continuous positive airway pressure is effective in high-resource settings, reducing the rate of continuous positive airway pressure failure, and the need for mechanical ventilation and surfactant. However, most deaths in preterm infants occur in low-resource settings without access to mechanical ventilation or surfactant. We hypothesize that in such settings, early continuous positive airway pressure will reduce the rate of failure and therefore preterm mortality., Methods: This is a mixed methods feasibility and acceptability, single-center pilot randomized control trial of early continuous positive airway pressure among infants with birthweight 800-1500 g. There are two parallel arms: (i) application of continuous positive airway pressure; with optional oxygen when indicated; applied in the delivery room within 15 min of birth; transitioning to bubble continuous positive airway pressure after admission to the neonatal unit if Downes Score ≥ 4 (intervention), (ii) supplementary oxygen at delivery when indicated; transitioning to bubble continuous positive airways pressure after admission to the neonatal unit if Downes Score ≥ 4 (control). A two-stage consent process (verbal consent during labor, followed by full written consent within 24 h of birth) and a low-cost third-party allocation process for randomization will be piloted. We will use focus group discussions and key informant interviews to explore the acceptability of the intervention, two-stage consent process, and trial design. We will interview healthcare workers, mothers, and caregivers of preterm infants. Feasibility will be assessed by the proportion of infants randomized within 15 min of delivery; the proportion of infants in the intervention arm receiving CPAP within 15 min of delivery; and the proportion of infants with primary and secondary outcomes measured successfully., Discussion: This pilot trial will enhance our understanding of methods and techniques that can enable emergency neonatal research to be carried out effectively, affordably, and acceptably in low-resource settings. This mixed-methods approach will allow a comprehensive exploration of parental and healthcare worker perceptions, experiences, and acceptance of the intervention and trial design., Trial Registration: The study is registered on the Pan African Clinical Trials Registry (PACTR) PACTR202208462613789.

Background: Pre-procedural antisepsis is a critical component of hospital-acquired infection prevention in the neonatal intensive care unit (NICU). However, broadly utilized topical antiseptic agents pose an elevated risk of disruption to neonatal skin integrity, and evidence-based guidelines are lacking. This systematic review of the literature sought to assess and characterize the predisposing risk factors for and types of neonatal skin injury from topical antiseptic agents., Methods: A systematic search of Medline Ovid, Embase, Web of Science, CINAHL, and Cochrane Library was conducted, including academic literature providing data on neonatal skin injuries related to topical antisepsis in the NICU., Results: A total of 19 articles (99 patients) met the inclusion criteria. Of the available data, most reported skin injuries were described in extremely preterm (98.1%) and very low birth weight (98.4%) infants. The majority of reported adverse cutaneous events were attributed to chlorhexidine preparations (74.8%), followed by octenidine (18.2%), povidone-iodine (6.1%), and isopropyl alcohol (2.0%). Erythema (40.1%), skin breakdown (23.4%), and chemical burns (17.5%) were the skin reactions reported most frequently, followed by skin irritation (8.3%), and skin necrosis (2.8%)., Conclusions: Our findings indicate that both extremely preterm and very low birth weight infants are particularly susceptible to skin toxicities from pre-procedural antiseptic preparations. These data underscore the need for future research to support the development of guidelines which minimize iatrogenic cutaneous injuries in the neonatal population, specifically for the care of infants under 2 months of age, for whom current recommendations are lacking due to a paucity of data., (© 2024 Wiley Periodicals LLC.)

Docosahexaenoic acid (DHA) supplementation has proven beneficial in reducing preterm births. However, the challenge lies in addressing nonadherence to prescribed supplementation regimens-a hurdle that significantly impacts clinical trial outcomes. Conventional methods of adherence estimation, such as pill counts and questionnaires, usually fall short when estimating adherence within a specific dosage group. Thus, we propose a Bayesian finite mixture model to estimate adherence among women with low baseline red blood cell phospholipid DHA levels (<6%) receiving higher DHA doses. In our model, adherence is defined as the proportion of participants classified into one of the two distinct components in a normal mixture distribution. Subsequently, based on the estimands from the adherence model, we introduce a novel Bayesian adaptive trial design. Unlike conventional adaptive trials that employ regularly spaced interim schedules, the novelty of our proposed trial design lies in its adaptability to adherence percentages across the treatment arm through irregular interims. The irregular interims in the proposed trial are based on the effect size estimation informed by the finite mixture model. In summary, this study presents innovative methods for leveraging the capabilities of Bayesian finite mixture models in adherence analysis and the design of adaptive clinical trials., Competing Interests: Data sharingFor data access, please see Carlson et al.5,15,16 Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Neonatologists and clinical neurophysiologists face challenges with the current electrodes used for long-duration amplitude-integrated electroencephalography (aEEG) in neonatal intensive care units (NICU), limiting the capacity to diagnose brain damage., Objectives: The objectives of this study were to develop methods for comparing the performance of different electrodes to be used in aEEG. The comparison was done between a newly designed neonate-specific electrode, aCUP-E, with commercial liquid gel electrodes used in amplitude-integrated electroencephalography (aEEG). The comparison included impedance stability, electrode survival, recording quality, usability, and satisfaction of NICU staff., Methods: aEEG recordings with bipolar montage was used, with one hemisphere fitted with commercial electrodes and the other with aCUP-E electrodes, alternated among subjects. Continuous impedance and raw EEG data were collected over a minimum of 24 h, and signal processing was performed using Python and MATLAB., Main Results: aCUP-E electrodes demonstrated superior performance, including: Increased impedance stability and electrode survival, enhanced recording quality with fewer artifacts, high correlation in signal capture between electrodes during optimal brain activity segments, higher signal-to-noise ratio (SNR) across varying impedance levels, greater staff satisfaction and ease of use. Moreover, Kaplan-Meier curves indicated a higher survival rate for aCUP-E electrodes over 24 h compared to commercial electrodes. Impedance variability analysis showed statistically significant stability improvements for aCUP-E., Conclusion: aCUP-E electrodes outperform commercial liquid gel electrodes in impedance stability, electrode survival, and recording quality. These results suggest that aCUP-E electrodes could significantly enhance aEEG utilization in diagnosing and treating neonatal brain conditions in NICUs. Future improvements to the aCUP-E electrode may further reduce artifacts and increase electrode longevity, potentially leading to a significant improvement in neonatal brain monitoring by means of aEEG., Competing Interests: Two authors of this paper, AF-S and VP-R, are authors of a patent (WO2021213985, "An electrode device for amplitude-integrated electroencephalography”) that is relevant to the research presented in this paper.

Objective: To explore the risk factors of delivery room (DR) resuscitation and assess the association of DR resuscitation with neonatal outcomes in very preterm infants (VPIs)., Methods: A multicenter retrospective cross-sectional study included VPIs with gestational age (GA) <32 weeks born between January, 2022 and June, 2023 and admitted to neonatal intensive care units of six tertiary hospitals in Shenzhen within 24 h after birth. They were divided into routine care group, positive-pressure ventilation (PPV) group, and endotracheal intubation (ETT) group based on the highest intensity of resuscitation received at birth. The association of antepartum and intrapartum risk factors and short-term outcomes with the intensity of DR resuscitation was evaluated., Results: Of 683 infants included in this study, 170 (24.9%) received routine care, 260 (38.1%) received bag and mask ventilation or T-piece ventilation and 253 (37%) received ETT. Among the antepartum and intrapartum factors, exposure to antenatal steroids (ANS) decreased the likelihood of ETT. Increasing GA decreased the likelihood of receiving a higher level of DR resuscitation. Among the neonatal outcomes, increasing intensity of DR resuscitation was associated with a raise in the risk of Bronchopulmonary dysplasia. Higher levels of DR resuscitation were associated with the risk of early-onset sepsis. ETT was significantly associated with an increased risk of death., Conclusion: Among VPIs, low GA and no ANS use increased the risk of high-intensity DR resuscitation interventions; and those who receiving ETT were associated with an increased risk of adverse clinical outcomes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (© 2024 Lin, Yu, Huang, Yang, Duan, Guo, Zeng, Jiang, Wang, Zhang, Ding and Liu.)

Background: Prematurity is associated with an increased risk of persistent wheezing but the underlying mechanisms are not well defined. The aim of this study was to identify blood transcriptional profiles associated with the development of wheezing in a cohort of moderate to late preterm infants and to define immune gene expression changes associated with wheezing., Materials and Methods: A convenience sample of a multicenter birth cohort (SAREPREM) of moderate-late preterm children followed during the first 3 years of life was analyzed. Children were enrolled in the first 2 weeks of life (Y0) and longitudinally evaluated at 1 (Y1), 2 (Y2), and 3 years (Y3) of age, for the presence of wheezing and to obtain samples for transcriptional profile analysis. Samples were processed on Illumina HT12 chips and genomic expression analyses performed with R programming, modular analysis for biological function, and QuSAGE for quantitative gene expression., Results: Seventy-six children were included in the study; 33 were classified as non-wheezing and 43 (56.6%) in the wheezing group. At Y0, children who developed wheezing had decreased expression of interferon genes and increased expression of B cell genes compared with the non-wheezing group. These changes in IFN and B cell gene expression were especially significant in children with late/persistent wheezing compared with transient wheezers., Conclusions: Changes in IFN and B lymphocyte gene expression identified in early life suggest the existence of specific immunological mechanisms that play an important role in the development of wheezing in late-preterm infants., (© 2024 European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

Multicystic dysplastic kidney (MCDK) is a congenital renal disease characterized by variable-sized noncommunicative cysts, impeding parenchymal development and functionality. Renal capabilities are relative to the functionality of the contralateral kidney and response to management. Unilateral and isolated cases are often asymptomatic with more positive outcomes, while severe bilateral derangements have a high mortality rate. We present a case of left-sided MCDK and right-sided renal dysplasia diagnosed at a nontertiary center. In addition, we offer a review of the epidemiology, epigenetics, and pathophysiology of MCDK. A concise discussion of prenatal, intrapartum, and postnatal renal function surveillance methods is presented to assist neonatal healthcare providers in collaborating with pediatric nephrology and urology specialists., (© 2024 Springer Publishing Company, LLC.)

Aim: Evaluate the additional burden of centralised neonatal care on families of extremely preterm infants cared for away from their planned hospital of birth., Methods: Retrospective cohort study using national data for infants 23 +0 to 27 +6 weeks of gestation admitted for neonatal care from 2011 to 2016. The number of transfers on the first day of life (potential maternal-infant separation), time away from the maternal booking hospital (BH) and distance from the maternal residence were quantified., Results: Of 14 719 included infants, 2803 (19%) underwent postnatal transfer on the first day of life. A total of 8622 (59%) infants were cared for away from their BH for a median of 39 days (interquartile range [IQR] 15-69), 30% spending >60 days away over a median of two episodes (range 1-12). Median return road travelling distances for parents to their local BH was 13 km (IQR 8-26), but this increased to 74 km (IQR 32-148) for those cared for in a non-BH., Conclusion: Centralised neonatal care improves infant outcomes but introduces additional burdens on the families of extremely preterm infants cared for away from their BH. Additional support, including accommodation and financial aid, could help minimise the impact on these families, facilitate family integrated care and improve parental wellbeing., (© 2024 The Author(s).

Adverse neonatal outcomes following in utero antipsychotic exposure remain unclear. This systematic review and meta-analysis aimed to investigate associations between in utero first- and second-generation antipsychotic exposure and various neonatal outcomes. The primary outcome was small for gestational age. Secondary outcomes included other birth weight-related measures, prematurity and neonatal outcomes. MEDLINE, EMBASE, CENTRAL, ICTRP, and ClinicalTrials.gov were searched for on 8th July 2023. Two reviewers independently selected studies reporting associations between exposure and neonatal outcomes (all designs were eligible, no language or time restriction) and extracted data. ROBINS-I was used for risk of bias assessment. Meta-analyses were performed. Measures of association were odds ratios and mean differences. Thirty-one observational studies were included. Regarding small for gestational age < 10th percentile, meta-analysis was only performed for second-generation antipsychotics and showed no evidence for an association (OR 1.31 [95%CI 0.83; 2.07]; I²=46%; p het =0.13, n = 4 studies). First-generation antipsychotics were associated with an increased risk of small for gestational age < 3rd percentile (OR 1.37 [95%CI 1.02; 1.83]; I²=60%; p het =0.04, n = 5) and a lower mean birthweight (MD -135 g [95%CI -203; -66]; I²=53%; p het =0.07, n = 5). Second-generation antipsychotics were associated with large for gestational age > 97th percentile (OR 1.56 [95%CI 1.31; 1.87]; I²=4%; p het =0.37, n = 4) and Apgar score < 7 (OR 1.64 [95%CI 1.09; 2.47]; I²=47%; p het =0.13, n = 4). Both types of antipsychotics were associated with increased risks of preterm birth and neonatal hospitalization. Despite potential confounding in the studies, this systematic review and meta-analysis showed that newborns of mothers using antipsychotics during pregnancy are potentially at risk of adverse neonatal outcomes.

Preterm birth represents a public health problem, with prematurity being the leading cause of infant mortality. An objective brain maturation and oxygenation measurement are necessary. The objective has been To test the feasibility of EEG and NIRS combination in the assessment of physiological brain maturation and oxygenation in preterm and non-preterm babies. A systematic review in Pubmed, Web of Science, MEDLINE, Cochrane, Dialnet, CINAHL, Scopus, Lilacs and PEDro databases until December 2022 was developed. 598 registers were found, finally 5 of them reached the inclusion criteria. Two independent reviewers analyzed data and a third reviewer were available for discrepancies. All articles combined EEG and NIRS to assess brain oxygenation and maturation in healthy new-born babies. There is an agreement on the electrode's placement for EEG at P3 and P4; besides, these regions have been shown to be a development predictive area, as well as the frontoparietal region for the NIRS region and comparison between regions. There is little evidence about the physiological brain electrical activity and oxygenation without stimuli.Conclusion: EEG and NIRS have been useful to assess brain electrical activity and oxygenation in preterm and non-preterm. The combined measurement of these instruments could be essential in neurological disorders diagnosis or their sequels. Unfortunately, the heterogeneity of the results found prevents a consensus on which variables are the most appropriate for the assessment of this population. What is Known • Brain assessment could help clinicians to prevent sequels. • There is an agreement for EEG electrodes placement at P3 and P4 region. What is New • EEG and NIRS assessment are effective measurements for preterm babies. • P3 and P4 regions have shown to be a predictive area of development, as well as the frontoparietal region for NIRS assessment., (© 2024.

Background: Necrotizing enterocolitis (NEC) is a major cause for morbidity and mortality among newborn infants. Chorioamnionitis is a perinatal complication that is associated with preterm delivery. Few reports have studied chorioamnionitis as a possible risk factor for NEC. Further investigation is needed to fully understand this association., Objective: To examine the association of chorioamnionitis with NEC in newborn infants., Methods: We used National Inpatient Sample (NIS) datasets produced by the federal Healthcare Cost and Utilization Project (HCUP). We identified infants born to mothers diagnosed with chorioamnionitis and infants born to mothers who did not have chorioamnionitis. The odds ratios (OR) to develop NEC in infants born to mothers affected by chorioamnionitis were calculated using chi square and Fisher Exact tests in the overall sample and in subgroups of different birthweight (BW) categories. The association was re-evaluated using logistic regression models to control for confounding variables., Results: The study identified 18,973,800 newborn infants admitted during the years 2016-2020. Among infants born to mothers with chorioamnionitis, NEC occurred in 0.9 % compared to 0.1 % in infants born to mothers without chorioamnionitis, (adjusted OR = 1.12, CI:1.02-1.15, p = 0.01). The prevalence of NEC in infants born to mothers with chorioamnionitis varied by the birth weight category, mainly for BW category 2500-4499 g (aOR = 1.61, CI:1.44-1.80, p < 0.001)., Conclusion: Maternal chorioamnionitis is associated with increased incidence of NEC, particularly in the BW category 2500-4499 g. Further studies are needed to examine the pathophysiological factors underlying this association., Competing Interests: Conflict of interest All authors declare that they have no competing interests to declare., (Published by Elsevier B.V.)

This observational study evaluated the validity of end-tidal CO 2 (ETCO 2 ) as a surrogate for arterial PCO 2 (PaCO 2 ) in infants on neurally adjusted ventilatory assist (NAVA), particularly considering the influence of variable spontaneous breathing on capnography waveforms. The study involved 16 infants, analyzing 50 paired ETCO 2 and PaCO 2 values. Deming regression analysis highlighted a notably stronger correlation for maximum ETCO 2 (r 2  = 0.6783, p <0.0001) compared to mean ETCO 2 (r 2  = 0.5686, p <0.0001) and demonstrated a significantly weaker association for minimum ETCO 2 (r 2  = 0.1838). These findings emphasize the superior predictive value of maximum ETCO 2 in estimating PaCO 2 , advocating its reliable use in clinical monitoring, especially given the dynamic capnography associated with NAVA's variable pressures. The results suggest ETCO 2 's potential to enhance noninvasive respiratory management, reduce the frequency of blood sampling, and improve overall care for infants requiring mechanical ventilation., (© 2023.

Thrombocytopenia is common in preterm neonates and can be associated with hemorrhage. Most platelet transfusions are prophylactic. Previously, higher platelet-count thresholds were recommended for neonates, but this recommendation has been questioned in recent studies. In the PlaNeT2 trial, mortality and serious bleeding were more frequent in neonates with the highest platelet-count threshold than in others. Following this trial, we changed our platelet transfusion practice by lowering the platelet-count threshold for prophylactic transfusion from 50,000 to 25,000/mm 3 . We conducted a before-after retrospective cohort study to quantify the frequency of platelet transfusions and assess the new protocol by analyzing death and serious hemorrhage events. This retrospective monocentric study included neonates born before 37 weeks of gestation with platelet count < 150,000/mm 3 during the 2 years preceding the new platelet transfusion protocol (high prophylactic transfusion threshold, 50,000/mm 3 ) and during the 2 years after the new platelet transfusion protocol (low prophylactic transfusion threshold, 25,000/mm 3 ). The primary outcome was the proportion of neonates receiving at least one platelet transfusion in both groups. We also compared the proportion of deaths and severe hemorrhage events. A total of 707 neonates with thrombocytopenia were identified. In the high-threshold group, 99/360 (27.5%) received at least one platelet transfusion as compared with 56/347 (16.1%) in the low-threshold group (p < 0.001). The groups did not differ in proportion of deaths or severe hemorrhage events., Conclusions: A reduced platelet-count threshold for transfusion allowed for a significant reduction in the number of platelet transfusions without increasing severe hemorrhage events., What Is Known: • A recent randomized trial suggested that restrictive platelet-count thresholds for platelet transfusion could be beneficial for preterm neonates., What Is New: • On lowering the platelet-count threshold for transfusion from 50,000 to 25,000/mm3, the number of transfusions significantly decreased without increasing severe hemorrhage events in a neonatal intensive care unit., (© 2024.

Background: Exposure to postnatal systemic inflammation is associated with increased risk of brain injury in preterm infants, leading to impaired maturation of the cerebral cortex and adverse neurodevelopmental outcomes. However, the optimal method for identifying cortical dysmaturation is unclear. Herein, we compared the utility of electroencephalography (EEG), diffusion tensor imaging (DTI), and neurite orientation dispersion and density imaging (NODDI) at different recovery times after systemic inflammation in newborn rats., Methods: Sprague Dawley rat pups of both sexes received single-daily lipopolysaccharide (LPS; 0.3 mg/kg i.p.; n = 51) or saline (n = 55) injections on postnatal days (P)1, 2, and 3. A subset of these animals were implanted with EEG electrodes. Cortical EEG was recorded for 30 min from unanesthetized, unrestrained pups at P7, P14, and P21, and in separate groups, brain tissues were collected at these ages for ex-vivo MRI analysis (9.4 T) and Golgi-Cox staining (to assess neuronal morphology) in the motor cortex., Results: Postnatal inflammation was associated with reduced cortical pyramidal neuron arborization from P7, P14, and P21. These changes were associated with dysmature EEG features (e.g., persistence of delta waveforms, higher EEG amplitude, reduced spectral edge frequency) at P7 and P14, and higher EEG power in the theta and alpha ranges at P21. By contrast, there were no changes in cortical DTI or NODDI in LPS rats at P7 or P14, while there was an increase in cortical fractional anisotropy (FA) and decrease in orientation dispersion index (ODI) at P21., Conclusions: EEG may be useful for identifying the early evolution of impaired cortical development after early life postnatal systemic inflammation, while DTI and NODDI seem to be more suited to assessing established cortical changes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Bronchopulmonary dysplasia (BPD) and neurodevelopmental impairment are among the most common morbidities affecting preterm infants. Although BPD is a predictor of poor neurodevelopmental outcomes, it is currently uncertain how BPD contributes to brain injury in preterm infants. Extracellular vesicles (EVs) are involved in interorgan communication in diverse pathological processes. ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain) is pivotal in inflammasome assembly and activation of inflammatory response. We assessed expression profiles of the alveolar macrophage (AM) markers CD11b, CD11c, and CD206 as well as ASC in EVs isolated from the plasma of preterm infants at risk for BPD at 1 week of age. We found that infants on higher fraction of inspired oxygen therapy (HO 2 ⩾30%) had increased concentrations of AM-derived EV-ASC compared with infants on lower fraction of inspired oxygen (LO 2 <30%). To assess the function of these EVs, we performed adoptive transfer experiments by injecting them into the circulation of newborn mice. We discovered that mice that received EVs from infants on HO 2 had increased lung inflammation, decreased alveolarization, and disrupted vascular development, the hallmarks of BPD. Importantly, these EVs crossed the blood-brain barrier, and the EVs from infants on HO 2 caused inflammation, reduced cell survival, and increased cell death, with features of pyroptosis and necroptosis in the hippocampus. These results highlight a novel role for AM-derived EV-ASC in mediating the lung-to-brain cross-talk that is critical in the pathogenesis of BPD and brain injury and identify potential novel targets for preventing and treating BPD and brain injury in preterm infants.

The aim of this study was to perform a retrospective data analysis of established peripheral artery catheters (pAC) in extremely preterm infants. The primary outcome was the pAC life span and its correlation to gestational age, birth weight, localizations, and pAC removal. Retrospective data analysis of electronic patient records of all extremely preterm infants (born less than 28 weeks gestation) admitted to the neonatal intensive care unit in Graz (Austria) between January 2014 and December 2020. A total of 196 preterm infants with a median (IQR) gestational age of 25.7 (24.6-26.6) weeks and a birth weight of 730 (614-898) g were included. In 155 (79%) of these preterm infants, 286 pAC and six umbilical artery catheters were inserted successfully. The first pAC was inserted 2.5 (1.4-7.4) h after birth, and the median pAC life span was 57.5 (22.-107.2) h. Gestational age, birth weight, and catheter localization did not correlate with the pAC life span. The pAC localizations were the radial artery (63%), tibial posterior artery (21%), ulnar artery (6%), dorsal artery of the foot (6%), others (1%), and not documented (3%). Adverse reactions including temporarily impaired peripheral perfusion, local inflammation, extravasation, or bleeding were reported in 13% of all pAC, but none of these resulted in long-term sequelae. A median (IQR) of 9 (5-18) arterial blood samples were drawn via pAC, resulting in a notable reduction of pain stimuli.Conclusion: The use of pAC in extremely preterm infants is feasible and safe. Neither gestational age, birth weight nor localization did affect the life span of pAC. No long-term sequelae were observed, and pain events were reduced by using pAC for blood drawing. What is Known: • Peripheral artery catheters can be used for continuous blood pressure measurement and blood draw even in extremely preterm infants. • (Severe) adverse reactions such as bleeding, necrosis, or amputation occur between 1 and 4%. • What is New: • The median peripheral arty catheter life span is 58 h and is not affected by gestational age, birth weight, nor localization. • A median of nine blood samples can be taken per each single pAC and, therefore, prevent pain events in extremely preterm infants., (© 2024.

Objective: To identify the most effective non-pharmacological measures for pain control in preterm infants in the Neonatal Intensive Care Unit (NICU)., Methods: A Systematic review and network meta-analysis of randomized clinical trials published in English, Portuguese, and Spanish from April 2020 to December 2023. The data sources used were MedLine via PubMed, LILACS, EMBASE, The Cochrane Central Register of Controlled Trials, and Pedro. We performed the risk of bias analysis with Rob 2 and the certainty of the evidence and strength of the recommendation using the Grading of Recommendations Assessment, Development, and Evaluation system. We assessed heterogeneity using the Higgins and Thompson I 2 test, the classification of interventions using the P-score, and inconsistencies using the Direct Evidence Plot., Results: From 210 publications identified, we utilized 12 studies in analysis with 961 preterm infants, and we combined ten studies in network meta-analysis with 716 preterm infants, and 12 combinations of non-pharmacological measures. With moderate confidence, sensory saturation, sugars, non-nutritive sucking, maternal heart sound, lullaby, breast milk odor/taste, magnetic acupuncture, skin-to-skin contact, and facilitated tucking have been shown to reduce pain in preterm infants when compared to no intervention, placebo, proparacaine or standard NICU routine: sensory saturation [SMD 5,25 IC 95%: -8,98; -1,53], sugars [SMD 2,32 IC 95%: -3,86; -0,79], pacifier [SMD 3,74 IC 95%: -7,30; 0,19], and sugars and pacifier SMD [3,88 IC 95% -7,72; -0,04]., Conclusion: Non-pharmacological measures are strongly recommended for pain management in preterm infants in the NICU., Implications for Clinical Practice: The findings of this study have important implications for policy and practice. This is the only systematic review that compared the effectiveness of non-pharmacological measures, thus making it possible to identify which measure presents the best results and could be the first choice in clinical decision making., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: Intraventricular hemorrhage (IVH) and germinal matrix hemorrhage (GMH) are the most common brain injuries in preterm infants. Neonates with these injuries are at greater risk of impaired neurodevelopmental outcome. Current guidelines recommend screening infants with cranial ultrasound (CUS); however, this is prone to missing subtle injury patterns, particularly within the posterior fossa. The present report sought to discuss the utility of diffusion tensor imaging (DTI) in preterm infants., Methods: A systematic review of PubMed, Ovid MEDLINE, and Ovid EMBASE was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included manuscripts were methodically scrutinized for quality, DTI use, and neurologic outcome., Results: Twenty studies with 1574 infants who underwent DTI were included. There were 574 preterm infants with GMH-IVH on DTI. Twelve studies documented decreased fractional anisotropy, whereas 6 demonstrated structural segregation and asymmetrical white matter myelination in these infants. Seven studies documented concurrent CUS use with 2 studies comparing DTI findings with CUS findings. In both studies, DTI more accurately detected presence of GMH, especially within the cerebellum. Among GMH-IVH preterm infants, 58.5% demonstrated cognitive, intellectual, and language delays at follow-up (mean, 32.4 months). Additionally, lower fractional anisotropy values on initial DTI were associated with cognitive, language, and motor delays., Conclusions: Although DTI is more sensitive for picking up subtle injury patterns, CUS remains the standard of care when screening for injuries that would necessitate surgical intervention. DTI offers a refined understanding of the sequelae of GMH-IVH with microstructural changes found on DTI being associated with childhood motor and cognitive outcomes., (Copyright © 2024 Elsevier Inc.

Background: Processing speed is a foundational skill supporting intelligence and executive function, areas often delayed in preterm-born children. The impact of early-life nutrition on gray matter facilitating processing speed for this vulnerable population is unknown., Methods: Magnetic resonance imaging and the Wechsler Preschool and Primary Scale of Intelligence-IV Processing Speed Index were acquired in forty 5-year-old children born preterm with very low birth weight. Macronutrient (grams per kilogram per day) and mother's milk (percentage of feeds) intakes were prospectively collected in the first postnatal month and associations between early-life nutrition and the primary outcome of brain regions supporting processing speed were investigated., Results: Children had a mean (SD) gestational age of 27.8 (1.8) weeks and 45% were male. Macronutrient intakes were unrelated, but mother's milk was positively related, to greater volumes in brain regions, including total cortical gray matter, cingulate gyri, and occipital gyri., Conclusion: First postnatal month macronutrient intakes showed no association, but mother's milk was positively associated, with volumetric measures of total and regional cortical gray matter related to processing speed in preterm-born children. This exploratory analysis suggests early-life mother's milk supports processing speed by impacting structural underpinnings. Further research is needed on this potential strategy to improve preterm outcomes., (© 2024 The Author(s).

Nebulized lung surfactant therapy has been a neonatology long-pursued goal. Nevertheless, many clinical trials have yet to show a clear clinical efficacy of nebulized surfactant, which, in part, is due to the technical challenges of delivering aerosols to the lungs of preterm neonates. The study aimed to test microbubbles for improving lung deposition in preterm neonates. An in vitro testing method was developed to replicate the clinical environment; it used a 3D-printed preterm neonate model, connected to a high-flow nasal cannula (HFNC) and a vibrating mesh nebulizer. The flow rate of the HFNC mirrored that used in the clinics (i.e., 4, 6, and 8 L/min). Followingly, the lung penetrations of aerosols with and without microbubbles were compared. The aerodynamic diameter of aerosols with microbubbles (MMAD=1.75 μm) was lower than that of the counterpart (MMAD=2.25 μm). Microbubble-laden aerosols had a significantly higher number of microbubbles that were below 1.0 μm. Microbubble-laden aerosols had dramatically higher lung penetration in the preterm model; lung penetration efficiencies were 30.0, 25.5, and 17.5 % at 4, 6, and 8 L/min, respectively, whereas the lung penetration efficiency for conventionally nebulized aerosols was below 1.25 % in the three flow rates., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Crown Copyright © 2024.

There are considerable researches on risk factors for necrotizing enterocolitis (NEC), focusing primarily on the entire course before onset. However, fewer studies address risk factors within the brief period before NEC occurrence. The current study aims to retrospectively analyze the clinical data of NEC patients while focusing on relevant risk factors in the preceding week of NEC onset. Infants born between January 2019 and December 2021 at Suzhou Municipal Hospital and Suzhou University Children's Hospital with a birth weight < 1500 g or a gestational age < 32 weeks were included. Around 54 NEC patients and 180 controls were recruited in the study. NEC patients satisfying the inclusion criteria formed the case group, while a 1:4 matching principle helped select the control group based on gestational age and birth weight. A statistically significant difference was observed between groups when red blood cell transfusions were compared the week before NEC onset (adjusted OR and 95% CI 2.16 (1.10, 4.24)). Broad-spectrum antibiotic usage before NEC occurrence was significantly lower in the NEC group than in the control group (adjusted OR and 95% CI 0.95 (0.91, 0.99)). A statistically significant difference was observed between groups while comparing patent ductus arteriosus (PDA) (adjusted OR and 95% CI 2.45 (1.23, 4.91)). The indication for packed red blood cell transfusion should be strictly controlled. Moreover, close monitoring of the patient's condition for NEC occurrence should be conducted within one-week post-transfusion. Accurately identifying infections and using broad-spectrum antibiotics can reduce the incidence of NEC., (© 2024. The Author(s).)

Background: Unlike in adult and pediatric patients, the usefulness of lactate in preterm infants has not been thoroughly discussed. This study aimed to evaluate whether the lactate level in the first hours of life is an important factor associated with neonatal death in very-low-birth-weight (VLBW) preterm infants., Methods: Electronic medical records from a level 4 neonatal intensive care unit in South Korea were reviewed to obtain perinatal and neonatal outcomes. Data on lactate levels of preterm infants in the first 12 h of life were collected. Neonatal mortality and morbidities were compared based on lactate levels. Subsequently, machine-learning models incorporating 20 independent variables, both with and without lactate, were compared for model performances and feature importance of lactate for predicting in-hospital mortality in the applicable models., Results: One hundred and sixty-eight preterm infants were included. Death rates on days 7 and 30 of life (D30-mortality) were significantly higher in infants with high lactate levels (≥3rd interquartile range) than in those with lower levels (<3rd interquartile range). Though statistically insignificant, the overall in-hospital mortality was more than twice as high in the high lactate level group than in the lower lactate level group. Based on the machine learning results, Random Forest, Gradient Boosting, and LightGBM models all showed greater area under the curves when lactate was included. Lactate consistently ranked in the variables of top five feature importance, particularly showing the greatest value in the Gradient Boosting model., Conclusion: Lactate levels during the early hours of life may be an important factor associated with in-hospital death of preterm VLBW infants. Based on the enhanced performance of the above-mentioned machine learning models, lactate levels in the early postnatal period may add to assessing the clinical status and predicting the hospital course in this population., Competing Interests: Declaration of competing interest The authors report there are no competing interests to declare., (Copyright © 2024 Taiwan Pediatric Association.

Background: One criterion for infant NICU discharge is the ability to meet all nutritional needs by mouth, therefore, it is important to understand interventions that can improve the trajectory to full oral feeding. While many oral motor and feeding interventions are used in clinical practice, it remains unclear which are supported by the literature., Aim: The aim of this integrative review was to identify and understand what oral motor interventions are defined in the literature to support positive outcomes for preterm infants and their parents., Methods: An integrative review of studies published from 2002 to 2022 focusing on applied oral motor interventions and their impact on feeding-related outcomes was completed. The systematic search used databases including PubMed, Cochrane, CINAHL, Scopus, and Google Scholar. Studies were included if they used a study population of preterm infants born

Background: Prematurity presents numerous barriers to mother's own milk (MOM) feeding and direct breastfeeding (DBF). Aim: This study aimed to determine factors associated with MOM feeding and DBF at discharge from the neonatal intensive care unit (NICU) in preterm-born infants presenting with feeding difficulties. Methods: A retrospective study of data from 237 preterm-born infants referred for evaluation of feeding difficulties and discharged home on full oral feeds was examined. Maternal and infant characteristics and oral feeding milestones were examined for their association with MOM intake and DBF at discharge using bivariate and multivariate regression analyses. Results: MOM feeding at discharge occurred in 35.4% ( n = 84) infants. The odds of any MOM feeding at discharge were higher with higher maternal age, absence of maternal substance use, and fewer days between full per oral (PO) and discharge (all, p < 0.05). Among the 84 MOM-fed infants, 4.76% ( n = 4) were exclusively breastfed, whereas 39.3% ( n = 33) were partially DBF at discharge. The DBF infants had higher birthweight, no incidence of being small for gestational age, lower incidence of respiratory support at birth and intraventricular hemorrhage, lower postmenstrual age (PMA) at full PO, shorter duration from first PO to full PO, and lower PMA at discharge (all, p < 0.05). Conclusion: We found reduced use of MOM and DBF among preterm-born infants with feeding difficulties at NICU discharge. Clinical management and research advocacy must focus on targeted interventions in this setting by recognizing significant modifiable factors applicable to prepregnancy, pregnancy, NICU, and postdischarge care.

Background/objectives: Breast cancer may negatively affect later pregnancy and childbirth. We aimed to analyze the impact of previous breast cancer on obstetric outcomes in postdiagnosis pregnancies., Methods: Insurance claims data in Southern Germany were used to identify breast cancer (BC) survivors with at least one subsequent delivery after cancer diagnosis between 2010 and 2020. In total, 74 BC survivors were compared to 222 age-matched controls with frequency matching on their age at their postdiagnosis delivery., Results: Endocrine therapy was associated with a significantly lower probability of birth compared to BC survivors without endocrine therapy (HR 0.36; 95% CI 0.18-0.53; p < 0.0001). The risks of preterm birth, low birth weight (LBW), gestational diabetes, hypertensive disorders, and cesarean section were not significantly increased among BC survivors compared to healthy controls. BC survivors were at an increased risk for a small-for-gestational-age (SGA) fetus (OR 3.24; 95% CI 1.17-8.97, p = 0.03). Delivery in less than 2 years after diagnosis increased the risk for SGA (OR 5.73; 95% CI 1.37-24.02, p = 0.03) and LBW (OR 4.57; 95% CI 1.32-15.87, p = 0.02)., Conclusions: Our findings are encouraging regarding the risks of preterm delivery, gestational diabetes, hypertensive disorders, and cesarean section to women who consider pregnancy after BC. Delivery in less than 2 years after diagnosis was associated with an increased risk for SGA and LBW.

Delivering adequate nutrition to preterm and sick neonates is critical for growth. Infants in the neonatal intensive care unit (NICU) require additional calories to supplement feedings for higher metabolic demands. Traditionally, clinicians enter free-text diet orders for a milk technician to formulate recipes, and dietitians manually calculate nutrition components to monitor growth. This daily process is complex and labor intensive with potential for error. Our goal was to develop an electronic health record (EHR)-integrated solution for entering feeding orders with automated nutrition calculations and mixing instructions. The EHR-integrated automated diet program (ADP) was created and implemented at a 52-bed level III academic NICU. The configuration of the parenteral nutrition orderable item within the EHR was adapted to generate personalized milk mixing recipes. Caloric, macronutrient, and micronutrient constituents were automatically calculated and displayed. To enhance administration safety, handwritten milk bottle patient labels were substituted with electronically generated and scannable patient labels. The program was further enhanced by calculating fortifier powder displacement factors to improve mixing precision. Order entry was optimized to allow for more complex mixing recipes and include a preference list of frequently ordered feeds. The EHR-ADP's safeguarded features allowed for catching multiple near-missed feeding administration errors. The NICU preterm neonate cohort had an average of 6-day decrease (P = 0.01) in the length of stay after implementation while maintaining the same weight gain velocity. The EHR-ADP may improve safety and efficiency; further improvements and wider utilization are needed to demonstrate the growth benefits of personalized nutrition., (© 2024 The Author(s).

Objective: To compare the neurodevelopmental outcomes of infants born at <29 weeks' gestation and exposed to diabetes in pregnancy with those unexposed., Study Design: This was a retrospective cohort study using the Canadian Neonatal Network and Canadian Neonatal Follow-Up Network databases. Infants born <29 weeks' gestation and admitted to a level 3 neonatal intensive care unit from 2009 through 2018 who had neurodevelopmental assessments at 18-24 months corrected age were eligible. The 2 primary outcomes were as follows: (1) Neurodevelopmental impairment (NDI) (≥1 of Bayley-III scores < 85 in any domain, cerebral palsy, or vision or hearing impairment); and (2) significant NDI (sNDI) (≥1 of Bayley-III scores < 70 in any domain, cerebral palsy Gross Motor Function Classification System ≥ 3, bilateral blindness, or need for hearing aids or cochlear implants). Secondary outcomes were the individual components of NDI and sNDI. Adjusted odds ratios with 95% CIs were calculated to determine outcomes between groups., Results: Of 13 988 eligible infants, 55% attended neurodevelopmental follow-up assessments. Infants exposed to diabetes had increased odds of NDI compared with those unexposed (aOR 1.09 (95% CI 1.08-1.54); there was no difference in sNDI (aOR 1.07 (95% CI 0.84-1.36). Language and motor delays were more common in those exposed to maternal diabetes., Conclusions: Higher rates of NDI, language, or motor delays were present in infants born at <29 weeks' gestation exposed to diabetes in utero. Future research is needed to determine the etiology and clinical significance of these findings., Competing Interests: Declaration of Competing Interest Although, there are no specific study sponsors, organizational support for the Canadian Neonatal Network and the Canadian Neonatal Follow-up Network was provided by the Maternal-infant Care Research Center (MiCare) at Mount Sinai Hospital in Toronto, Ontario, Canada.

Introduction Bronchiolitis poses a significant challenge in pediatric critical care. It is an acute illness affecting the lower respiratory tract in children under the age of two. The most common cause of bronchiolitis is the seasonal respiratory syncytial virus, with influenza and adenovirus also notable contributors. It is characterized by various clinical symptoms and indicators, such as an upper respiratory prodrome, increased respiratory effort, and wheezing in younger children under two years old. This study primarily examines the clinical profile, risk factors, severity, and outcomes of bronchiolitis in children under two years, excluding the neonatal age group.  Materials and methods Children under two years of age who presented with upper respiratory symptoms and their first episode of wheezing were evaluated. Those with pre-existing systemic conditions such as cardiac, respiratory, or immunodeficiency disorders were excluded. A detailed history was gathered using a questionnaire, and risk factors were analyzed. The severity of the condition was measured using the Wood-Downes-Ferres score. Data analysis was performed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States). The relationship between risk factors, severity, and outcomes was examined using the chi-squared test. A two-sided probability of p<0.05 was considered statistically significant for all tests. Results Among 54 children aged 1-24 months with bronchiolitis, the average age was 10.18 months, with a standard deviation of 4.8 months. The severity of the condition was greater in younger children (1-12 months) and tended to decrease with age. Bronchiolitis was more common in males (33 cases) than females (21 cases). Approximately 50 children (92.6%) exhibited signs of respiratory distress, and 45 children (83.3%) showed cough as an initial symptom. Severity was notably higher in children with a history of irritability, which was statistically significant (chi-squared value: 8.169; p-value: 0.017). Only 16 children (29.65%) had a history of poor feeding. Bronchiolitis was more prevalent among infants with a birth weight under 1500 grams (63%). Non-exclusive breastfeeding and early bottle feeding were significant risk factors for bronchiolitis and its severity (chi-squared values: 18.794; p-value: 0.000 and 7.795; p-value: 0.020, respectively). Only two children (3.7%) had been exposed to passive smoke, and the severity was slightly higher in these cases. There was also a statistically significant association between socioeconomic status and bronchiolitis (chi-squared value: 11.917; p-value: 0.018). Conclusion This study aims to raise awareness among parents and clinicians about the high-risk age group for bronchiolitis, its typical presentations, and predictors of severity. It underscores the impact of both biological and environmental risk factors, such as bottle feeding, non-exclusive breastfeeding, and socioeconomic status, on the severity of the condition., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Preterm infants are at risk of complications due to their prematurity and Retinopathy of Prematurity (ROP) is one of them. To discover and treat ROP the preterm infants regularly undergo eye examinations. Nurses are responsible for the infants' care during this painful and stressful procedure., Aim: The aim of this study was to explore nurses' perceptions of preterm infants' eye examinations., Methods: Data were collected through semi-structured interviews with 10 nurses experienced in participating in preterm infants' eye examinations. Data were analysed using a phenomenographic approach., Results: The results showed several perceptions of the eye examinations, and the analysis resulted in four descriptive categories: Infants are affected by the eye examination; Nurses have comprehensive overall responsibility for the infants; Parents are important to their infants, but they need support to fulfil their parental role, and Collaboration is important for the examination's favourable outcome. The category Nurses have comprehensive overall responsibility for the infants was regarded as the most comprehensive, covering all the other categories., Conclusions: Nurses felt a great responsibility during a painful and stressful procedure for preterm infants. Infants' well-being could be better protected by interprofessional collaboration, improved nursing care and involved parents., (© 2024. The Author(s).)

Introduction: This study was undertaken to find the clinical correlation of resistive index (RI) in the anterior cerebral artery (ACA) of preterm neonates admitted to the Neonatal Intensive care unit (NICU) with comorbidities such as perinatal asphyxia, neonatal sepsis, and necrotizing enterocolitis (NEC)., Methods: An observational analytical study was conducted, including preterm neonates (<35 weeks) admitted to the NICU. Ultrasound cranium scans were performed on days 1-3 and 7 of life as per the study protocol. Baseline and clinical data of asphyxia, sepsis, and NEC were obtained. Images were acquired using a 4-8-MHz probe on a Sonosite M-turbo machine (Bothell, WA, USA). All statistical calculations were done using SPSS version 21.0 (SPSS Inc., Chicago, IL, USA) with the application of the Kolmogorov-Smirnov test and the Mann-Whitney test., Results: During the study period, a total of 739 neonates were admitted. Of these, 73 neonates constituted the study group. Among the 73 patients, 33 were preterm neonates without comorbidities and 40 neonates had comorbidities such as perinatal asphyxia, sepsis, and NEC stage 2 and 3 (necrotizing enterocolitis). In the present study, the mean RI on day 3 of life was 0.76 ± 0.04 in neonates without comorbidities and 0.77 ± 0.04 in neonates with comorbidities, with a p -value of 0.247. On the 7th day of life, the mean RI was 0.82 ± 0.03 in both groups, with a p -value of 0.42., Conclusion: We could not find any significant clinical correlation of RI in the ACA of preterm neonates <35 weeks of gestation with comorbidities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Gill, Gupta, Pooni and Bhargava.)

Purpose: The study was conducted as a randomized controlled experimental study to investigate the effects of music therapy application on physiological parameters and pain in preterm infants.", Materials and Methods: Preterm newborns included in the study were divided into 3 groups. The first group is experiment I, in which lullabies sung by the babies' own mothers were recorded and played. The second group is experiment II, where lullabies recorded with a standard female vocal for babies are played. The third group is the Control group in which no intervention is applied to the babies. The heart rate and respiratory rate, oxygen saturation level (SpO2) values and pain scores of the groups were measured and compared at different times., Results: Lullaby exposure did not yield significant differences between groups in terms of physiological parameters and pain scores. However, statistical significance was observed in the post-lullaby heart rate, respiratory rate, oxygen saturation level, and pain scores of infants in the experimental group (p < 0.05). Significance was consistent across all measurements taken 15 min after the IV intervention., Conclusion: Listening to lullabies has beneficial effects on physiological parameters and pain reduction in preterm infants. Integrating lullaby exposure into the regular supportive care of neonatal intensive care unit infants, conducting further studies with more diverse sample groups, and exploring various types of lullabies and music are recommended., Practice Implications: Lullaby during invasive procedures may reduce pain and improve physiologic symptoms in preterm infants. Our findings support the integration of lullabies into the daily supportive care of preterm infants., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest., (Copyright © 2024 Elsevier Inc.

Background: As the Sustainable Development Goal 3.2.1 deadline (2030) approaches, rapidly reducing under-5 mortality (U5M) gains more prominence. However, initiatives or interventions that aided Bangladesh in achieving Millennium Development Goal 4 showed varied effectiveness in reducing certain cause-specific U5M. Therefore, this study aimed to examine the predictors of the key cause-specific mortalities., Methods: This cross-sectional study was conducted using the Bangladesh Demographic and Health Survey 2011 and 2017-18 data. Cause-specific U5M was examined using multilevel multinomial mixed-effects analyses, and overall/all-cause U5M was examined using multilevel mixed-effects analyses. The respective estimates were compared., Results: The cause-specific analysis revealed that pneumonia and prematurity-related U5M were significantly associated with antenatal care and postnatal care, respectively. However, analysis of overall/all-cause U5M did not reveal any significant association with health services. Twins or multiples had a greater risk of mortality from preterm-related conditions (adjusted Relative Risk Ratio (aRRR): 38.01, 95% CI: 19.08-75.7, p < .001), birth asphyxia (aRRR: 6.52, 95% CI: 2.51-16.91, p < .001), and possible serious infections (aRRR: 11.12, 95% CI: 4.52-27.36, p < .001) than singletons. Children born to mothers 18 years or younger also exhibited a greater risk of mortality from these three causes than children born to older mothers. This study also revealed an increase in the predicted risk of prematurity-related mortality in the 2017-18 survey among children born to mothers 18 years or younger, children born to mothers without any formal education, twins or multiples and children who did not receive postnatal care., Conclusions: This research provides valuable insights into accelerating U5M reduction; a higher risk of preterm-related death among twins underscores the importance of careful monitoring of mothers pregnant with twins or multiples through the continuum of care; elevated risk of death among children who did not receive postnatal care, or whose mothers did not receive antenatal care stresses the need to strengthen the coverage and quality of maternal and neonatal health care; furthermore, higher risks of preterm-related deaths among the children of mothers with low formal education or children born to mothers 18 years or younger highlight the importance of more comprehensive initiatives to promote maternal education and prevent adolescent pregnancy., (© 2024.

Context: This study aimed to study feto-maternal outcomes in women with preterm prelabor rupture of membranes (PTPROM) on expectant management versus delivery at 34 weeks of gestation and correlate the period of latency and inflammatory markers with delivery outcomes. We have chosen this research topic as there is a paucity of specific guidelines regarding the optimal period of gestation for delivering women with PTPROM., Aim: The study correlated the feto-maternal outcomes in women with PTPROM on expectant management till 37 weeks versus delivery at 34 weeks with a period of latency and maternal inflammatory markers., Methods and Materials: This was a prospective observational study conducted on 262 women with PTPROM from 28-33+6 weeks of gestation. Women were monitored till 37 weeks with biweekly total leukocyte count and weekly C-reactive protein, urine routine microscopy, urine culture, high vaginal culture sensitivity, and ultrasound. Women were monitored expectantly till 37 weeks. However, intervention was done at any time during the feto-maternal compromise. There were 52 women who delivered <34 weeks and 210 women who delivered ≥34 weeks. Feto-maternal outcomes were documented. Group A was assigned to women who delivered before 34 weeks and Group B was assigned to women who delivered after 34 weeks. Statistical analysis was done using SPSS software. A p-value <0.05 was considered significant., Results: Among the study group, 238 (90.8%) women were managed expectantly while 24(9.1%) required intervention. A latency of 3-4 weeks was observed in 131(50%) women. Chorioamnionitis developed in 7 women (4.4%) in group A and 13 women (4.9%) in group B. Neonates developed sepsis in 5.7% in group A and 5.8 % in group B and were comparable in both the groups (p=1.000). Early neonatal death (END) occurred in 10 (3.8%) among which seven died because of low birth weight (LBW), two due to sepsis, and one due to respiratory distress. LBW was significantly associated with END (p<0.001) Conclusion: Expectant management beyond 34 weeks with close monitoring can improve neonatal outcomes without increasing maternal morbidity in women with PTPROM., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Introduction: Children who have experienced the coronavirus disease 2019 (COVID-19) pandemic are at an increased risk of adverse neurologic developmental outcomes. Limited data exist on the environmental influences of during the COVID-19 pandemic on preterm infant development. This study aimed to investigate whether COVID-19 exposure affects the neurodevelopmental outcomes in preterm children up to 3 years of age., Methods: This prospective cohort study included all very low birth weight (VLBW) infants from the Korean Neonatal Network who had undergone a neurodevelopmental assessment between January 2015, and May 2022. The neurodevelopmental outcomes along with the scores on the Bayley Scales of Infant and Toddler Development (BSID) and the Korean Developmental Screening Test for Infants and Children of pediatric patients aged 18-24 and 33-39 months who were exposed to COVID-19 were compared with those of VLBW children born and tested before the pandemic., Results: The cohort included 1,683 VLBW infants. The pandemic group had significantly lower language scores on the BSID-III at ages 18-24 months ( p  = 0.021) and 33-39 months ( p  = 0.023) than the pre-pandemic group after adjusting for gestational age, morbidity, and environmental factors. At 2nd follow-up period, the pandemic group showed significantly lower scores in the cognitive ( p  = 0.026) domains with a mean difference of 7 points and had a significantly higher percentage of ≤-1SD in the gross motor domain ( p  < 0.001) compared with the pre-pandemic group., Conclusion: Preterm children who experienced the COVID-19 pandemic are at higher risk of abnormal neurodevelopmental outcomes in the first 3 years of life than preterm infants born before the COVID-19 pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Kim, Jang, Lee, Lee, Sung, Kim, Lee, Yang, Kim, Yoon, Ahn and Lee.)

Preterm births comprise all pregnancies coming to an end before the gestational age of 37 weeks and remain the leading cause of death in children under 5 years old despite efforts to reduce their occurrence. We aim to analyze all morbidity and mortality data to understand causes and risk factors, helping in prevention efforts. This study includes 140 cases collected during 2018-2022. Demographic, maternal, and thanatogenetic data were statistically analyzed. We observed an upward slope of stillborn babies. In the case of live-born premature, the average survival was 301.76 h. The multivariate analysis noted that extremely low birth weight (HR = 5.141) and very low birth weight (HR = 4.177) are risk factors involved in mortality. Increased parity was associated with premature births with low and very low birth weight ( p = 0.019). We observed that a mother's age of over 30 years is predictable for the development of pregnancy-induced hypertension. Cerebral and pulmonary hemorrhages were the most common intermediate morbid conditions, with prematurity and plurivisceral hemorrhages serving as their root causes. We have identified that anthropometric measurements have a high predictability on malformed babies. The identified associations indicate a shared mechanism for certain lesion processes, which can help optimize resources for predicting and preventing preterm neonatal issues.

One in ten babies are born preterm, as defined as being less than 37 weeks of gestational age. Premature births are associated with a high risk of poor neurodevelopmental outcomes, including hearing, visual, motor, and cognitive impairments. Currently, there is no specific standardization for neurological follow-up infants born premature. Most formal neonatal intensive care units, follow-up programs monitor children until early childhood. However, some deficits, such as mild cognitive impairment, may only become apparent in school years. This review outlines a neurological follow-up timeline, as well as the different standardized measures that can be used to monitor development to ensure that children born preterm receive timely and appropriate therapies and services.

Introduction: Many preterm present somatic symptoms including aerodigestive and cardiorespiratory manifestations, in combination with irritability and/or distress, which are often attributed to gastroesophageal reflux (GER), albeit for unclear reasons., Areas Covered: We searched in PubMed, Google Scholar, and MEDLINE for guidelines, reviews, and randomized controlled trials up to March 2024., Expert Opinion: The diagnosis of GER-disease (GERD) in preterm is challenging because manifestations are atypical and diagnostic investigations difficult and not devoid of risk for adverse events. In case of vomiting or regurgitation, GER as a consequence of anatomical or metabolic conditions should be considered. Although many preterm infants are treated with proton pump inhibitors, this is seldom needed. Low-quality evidence for alginates is available, but needs further evaluation. There is a need for an effective and safe prokinetic favoring esophageal clearance, increasing lower esophageal sphincter pressure and stimulating gastric emptying. Non-drug treatment such as feeding adaptations (volume, duration, and composition) and positional changes are insufficiently applied. Thickened formula is not indicated in preterm babies. In case none of the above recommendations did result in sufficient improvement, and if documentation of acid GER is not possible, a 2-4 week trial of a proton pump inhibitor is acceptable.

Sepsis is a leading cause of death in preterm neonates. The increased susceptibility to sepsis is due to prolonged hospitalization, the need for invasive procedures, and immaturity of innate and adaptive immunity. Chlorhexidine gluconate is a popular topical disinfectant that was not recommended for use in preterm neonates until 2012. Thus, there are few studies assessing the role of chlorhexidine gluconate in antisepsis for preterm neonates. A better understanding of the safety and efficacy of chlorhexidine gluconate as an antiseptic agent for preterm neonates is the first step in establishing best practice guidelines for this population., (© 2024 Wiley Periodicals LLC.)

Objective: To assess prescribing practices and perspectives regarding the use of corticosteroids in the management of neonatal hypotension., Methods: Cross-sectional questionnaire-based electronic survey of neonatologists (n = 206) practicing at tertiary neonatal intensive care units across 30 academic centres in Canada., Results: The overall response rate was 33% (72/206), with a completion rate was 94%. Most (48/72, 64%) worked in a unit that covered both inborn and outborn infants, and 53% (37/70) worked in units with >100 very low birth weight infants admitted annually. Among the 72 respondents, 39% use a loading dose, of whom most (57%) use 2 mg/kg. Dosing ranges were variable, most using either 0.5 mg/kg or 1 mg/kg, q6h. Among the 56% (40/72) of neonatologists who reported measuring cortisol before initiation of hydrocortisone, cut-offs for initiation of hydrocortisone varied from <100 to <500 nmol/L, most of whom (48%) used <100 nmol/L. Of 71 respondents, 92% (65) indicated that a randomized control trial examining the use of corticosteroids in neonatal hypotension is needed, of whom 52% (37) indicated that the intervention group should receiving hydrocortisone after one vasopressor/inotrope., Conclusions: This survey provides insight into the prescribing practices of tertiary neonatologists with regards to the use of corticosteroids in neonatal hypotension. While corticosteroids are frequently prescribed, there is variability in the indication, dosing, and duration of corticosteroid use. The findings from this survey can be used to inform further research, including a clinical trial, regarding the practice in the management of neonatal hypotension., Competing Interests: Declaration of competing interest The authors have no disclosures or conflicts of interest., (Copyright © 2024 Taiwan Pediatric Association.
