Objective Hypoxic–ischemic encephalopathy (HIE) is a leading cause of morbidity and mortality in neonates. Therapeutic hypothermia (TH) has improved outcomes and mortality in infants with >36 weeks' gestational age (GA) with moderate-to-severe HIE. There are limited data on the safety and efficacy of TH in preterm infants with HIE. This study describes our experience and examines the safety of TH in neonates with <36 weeks' GA. Study Design A single-center, retrospective study of preterm neonates born at <36 weeks' GA with moderate-to-severe HIE and treated with TH, compared to a cohort of term neonates with HIE (≥37 weeks' GA), was conducted. The term cohort was matched for degree of background abnormality on electroencephalogram, sex, inborn versus outborn status, and birth year. Medical records were reviewed for pregnancy and delivery complications, need for transfusion, sedation and antiseizure medications, electroencephalography and imaging findings, and in-hospital mortality. Results Forty-two neonates born at <36 weeks' GA with HIE received TH between 2005 and 2022. Data from 42 term neonates were analyzed for comparison. The average GA of the preterm cohort was 34.6 weeks and 39.3 weeks for the term cohort. Apgar scores, degree of acidosis, and need for blood product transfusions were similar between groups. Preterm infants were more likely to require inotropic support (55 vs. 29%, p = 0.026) and hydrocortisone (36 vs. 12%, p = 0.019) for hypotension. The proportion of infants without evidence of injury on magnetic resonance imaging was similar in both groups: 43 versus 50% in preterm and term infants, respectively. No significant difference was found in mortality between groups. Conclusion In this single-center cohort, TH in preterm infants appears to be as safe as in term infants, with no significant increase in intracranial bleeds or mortality. Preterm infants more frequently required inotropes and steroids for hypotension. Further research is needed to determine efficacy of TH in preterm infants. Key Points TH is used off-protocol in preterm infants. Preterm and term infants have similar mortality. Preterm cohort required more inotropic support. [ABSTRACT FROM AUTHOR]

Objective Neonatal intensive care units (NICUs) account for over 35% of pediatric in-hospital costs. A better understanding of NICU expenditures may help identify areas of improvements. This study aimed to validate the Canadian Neonatal Network (CNN) costing algorithm for seven case-mix groups with actual costs incurred in a tertiary NICU and explore drivers of cost. Study Design A retrospective cohort study of infants admitted within 24 hours of birth to a Level-3 NICU from 2016 to 2019. Patient data and predicted costs were obtained from the CNN database and were compared to actual obtained from the hospital accounting system (Coût par Parcours de Soins et de Services). Cost estimates (adjusted to 2017 Canadian Dollars) were compared using Spearman correlation coefficient (rho). Results Among 1,795 infants included, 169 (9%) had major congenital anomalies, 164 (9%) with <29 weeks' gestational age (GA), 189 (11%) with 29 to 32 weeks' GA, and 452 (25%) with 33 to 36 weeks' GA. The rest were term infants: 86 (5%) with hypoxic–ischemic encephalopathy treated with therapeutic hypothermia, 194 (11%) requiring respiratory support, and 541 (30%) admitted for other reasons. Median total NICU costs varied from $6,267 (term infants admitted for other reasons) to $211,103 (infants born with <29 weeks' GA). Median daily costs ranged from $1,613 to $2,238. Predicted costs correlated with actual costs across all case-mix groups (rho range 0.78–0.98, p < 0.01) with physician and nursing representing the largest proportion of total costs (65–82%). Conclusion The CNN algorithm accurately predicts NICU total costs for seven case-mix groups. Personnel costs account for three-fourths of in-hospital total costs of all infants in the NICU. Key Points Very preterm infants born below 33 weeks of gestation account for most of NICU resource use. Human resources providing direct patient care represented the largest portion of costs. The algorithm strongly predicted total costs for all case-mix groups. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Premature infants have less physiologic reserve and often delayed vaccination compared to full-term infants. The birth dose of hepatitis B vaccine (HepB-BD) is an essential measure to achieve the goal of "zero infections" of hepatitis B virus in all newborns. However, there are few investigations of hepatitis B vaccination of preterm infants, leading to uncertainty of coverage and insufficient knowledge of factors influencing timely vaccination of this important population. Methods: We obtained hepatitis B vaccine (HepB) vaccination histories of premature infants born during 2019–2021 in three provinces from the respective provincial immunization information systems. Extracted data included date of birth, sex, region, and dates of HepB administration. We conducted descriptive analyses that included basic characteristics of the study subjects, HepB-BD administration, and full-series HepB vaccination. Factors potentially influencing HepB-BD and full series vaccination were analyzed by logistic regression. Results: There were 1623 premature infants included in the analytic data set. Overall HepB-BD coverage was 71.41%; coverage among premature infants born to mothers with unknown hepatitis B surface antigen (HBsAg) status was 69.57%; coverage was higher at county-level-and-above hospitals (72.02%) than hospitals below county level (61.11%). Full-series HepB coverage was 94.15%; full-series coverage among preterm infants weighing less than 2000 g at birth was 76.92%. Logistic regression showed that the HepB-BD vaccination rate was positively associated with being born to an HBsAg-positive mother and being preterm with high birth weight. Regression analysis for factors influencing full-series HepB coverage showed that being born prematurely was positively associated with full-series coverage and being premature with a very low birth weight was negatively associated with full-series coverage. Conclusions: HepB-BD coverage levels in three provinces of China were less than the target of 90%, especially among premature infants born to mothers with unknown HBsAg status and at hospitals below the county level. Screening of pregnant women should be a universal normal standard. Hepatitis B vaccination training should be strengthened in hospitals to improve the HepB-BD vaccination rate of premature infants and to effectively prevent mother-to-child transmission of hepatitis B virus.

Less invasive surfactant administration (LISA) has become the preferred method of surfactant administration for spontaneously breathing babies on continuous positive airway pressure (CPAP).Background: The development of LISA followed the need to combine CPAP and surfactant replacement as mainstay treatment options for respiratory distress syndrome, thereby avoided exposure to positive pressure ventilation.Summary: This review summarises the current knowns and unknowns of LISA including the physiological concept, its relevance for short-term and long-term outcomes and the challenges for practical implementation of LISA as part of a less invasive respiratory care bundle. Further, we provide an update of the evidence on alternatives to LISA, for example, nebulised surfactant administration, pharyngeal deposition of surfactant and delivery via supraglottic airway.

Aim Methods Results Conclusion Concerns exist regarding potential adverse neurodevelopmental outcomes associated with paracetamol exposure during pregnancy and early infancy. This review evaluates the evidence for the impact of paracetamol use for patent ductus arteriosus (PDA) treatment on neurodevelopmental outcomes in preterm infants.A literature search was performed via Medline, Ovid Embase and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. The search details are below: (‘Infant, Newborn’ [MeSH] OR ‘neonate*’ [Title/Abstract]) AND (‘Paracetamol’ [MeSH] OR ‘Acetaminophen’ [Title/Abstract]) AND (‘Ductus Arteriosus, Patent/drug therapy’ [MeSH] OR ‘patent ductus arteriosus’ [Title/Abstract]) AND (‘Neurodevelopmental Disorders’ [MeSH] OR ‘neurodevelopment*’ [Title/Abstract] OR ‘Child Development’ [MeSH] OR ‘Developmental Disabilities’ [MeSH]). All studies were critically appraised and synthesised.Seven studies reported neurodevelopmental outcomes after paracetamol use for PDA treatment in preterm infants <32 weeks gestation. The studies varied in dosage, route, and duration of paracetamol administration and in the methods used to assess neurodevelopmental outcomes. None of the studies revealed different outcomes between paracetamol‐exposed preterm infants and controls.Current low‐to‐moderate quality evidence suggests no association between paracetamol used for PDA treatment and adverse neurodevelopmental outcomes in preterm infants. Future well‐powered studies with standardised neurodevelopmental assessments are warranted to strengthen the current evidence base. [ABSTRACT FROM AUTHOR]

- Abstract
Fragestellung – Frühgeborene stellen einen nicht unerheblichen Anteil an der gesamten Geburtenzahl dar. Dabei treten bei ihnen, bedingt durch das Gestationsalter und daraus resultierenden Komplikationen, zum Teil schwere Beeinträchtigungen auf, die das Leben des Kindes und seiner Familie prägen. Die Studie sollte untersuchen, welche Bedeutung Osteopathie für frühgeborene Kinder haben kann. Methodik – 12 Kinderosteopath*innen wurden mithilfe von Leitfadeninterviews zur Gestaltung des osteopathischen Behandelns, zu relevanten Strategien und Aspekten befragt. Die Befragungen wurden wörtlich transkribiert und mithilfe der qualitativen Inhaltsanalyse nach Mayring ausgewertet. Ergebnisse – Die befragten 12 Kinderosteopath*innen gaben an, ihr Behandeln individuell auf die Bedürfnisse der Frühgeborenen abzustimmen. Hierbei wurden gerade die interdisziplinäre Zusammenarbeit und das Einbinden der Eltern als bedeutsam angesehen. Schlussfolgerung – Osteopathie kann laut den befragten Kinderosteopath*innen die Beschwerden der Frühgeborenen und die Rahmenbedingungen für ihre Entwicklung verbessern. Zudem kann das osteopathische Behandeln in einer interdisziplinären Zusammenarbeit andere Therapieverfahren ergänzen und scheint deshalb für ein optimales Outcome von Bedeutung zu sein. Objective – Preterm infants represent a significant proportion within the total birth rate. According to the gestational age and possible complications, premature infants sometimes suffer from severe impairments which influence the life of the child and its family. The purpose of this study was to investigate the importance of osteopathic treatment for preterm infants. Methods – Semistructured interviews were used to investigate the pediatric osteopaths' view about osteopathic treatment of preterm infants and relevant strategies and aspects. The interviews were transcribed and analyzed using qualitative content analysis according to Mayring. Results – The 12 interviewed pediatric osteopaths stated that they adapted their treatment according to the individual needs of the premature infant. In this context, interdisciplinary cooperation and the involvement of the parents were considered to be particular important. Conclusion – Osteopathic treatment can improve the impairment of preterm infants and the general conditions for their development according to the pediatric osteopaths' opinion. Moreover, the osteopathic treatment might complement other therapeutic procedures in an interdisciplinary collaboration and therefore seems to be important for an optimal outcome.

Objective: To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. Method: Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson’s correlation. The study considered a significance level of 0.05. Results: There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. [ABSTRACT FROM AUTHOR]

Introduction: Several studies demonstrate the relationship between preterm birth and a reduced thalamus volume at term-equivalent age. In contrast, this study aims to investigate the link between the thalamic growth trajectory during the early postnatal period and neurodevelopment at two years of age. Methods: Thalamic volume was extracted from 84 early MRI scans at postmenstrual age of 32.33 (± 2.63) weeks and 93 term-equivalent age MRI scans at postmenstrual age of 42.05 (± 3.33) weeks of 116 very preterm infants (56% male) with gestational age at birth of 29.32 (± 2.28) weeks and a birth weight of 1158.92 (± 348.59) grams. Cognitive, motor, and language outcomes at two years of age were assessed with Bayley Scales of Infant and Toddler Development Third Edition. Bivariate analysis was used to describe the clinical variables according to neurodevelopmental outcomes and multilevel linear regression models were used to examine the impact of these variables on thalamic volume and its relationship with neurodevelopmental outcomes. Results: The results suggest an association between severe brain injury and thalamic growth trajectory (β coef = -0.611; p < 0.001). Moreover, thalamic growth trajectory during early postnatal life was associated with the three subscale scores of the neurodevelopmental assessment (cognitive: β coef = 6.297; p = 0.004; motor: β coef = 7.283; p = 0.001; language: β coeficient = 9.053; p = 0.002). Discussion: These findings highlight (i) the impact of severe brain injury on thalamic growth trajectory during early extrauterine life after preterm birth and (ii) the relationship of thalamic growth trajectory with cognitive, motor, and language outcomes.

Aim Methods Results Conclusion To assess the effect of ventricular decompression on cerebral oxygenation in preterm neonates with intraventricular haemorrhage (IVH) and posthemorrhagic ventricular dilatation (PHVD) using near‐infrared spectroscopy (NIRS).Fifty‐three preterm neonates born <34 weeks' gestation between 2013 and 2023 with IVH and subsequent PHVD were prospectively included. Regional cerebral oxygen saturation (rScO2) as well as fractional cerebral tissue oxygen extraction (cFTOE) were analysed 2 weeks before and after ventricular decompression.Ventricular decompression was performed at 18 ± 6 days of life. Patients with repeated lumbar punctures prior to ventricular drainage showed consistently higher rScO2 and lower cFTOE levels 2 weeks before and after intervention compared to those without. Patients who underwent direct ventricular drainage showed an immediate increase in rScO2 levels on the day of the procedure. In patients who underwent prior lumbar punctures, ventricular decompression did not yield additional acute effects on cerebral oxygenation.Patients who underwent repeated lumbar punctures preceding ventricular drainage consistently maintained higher rScO2 and lower cFTOE levels during the study period. In these patients, ventricular decompression did not further affect cerebral oxygenation, as they already demonstrated improved cerebral hemodynamics, whereas an immediate improvement was observed in those without prior lumbar punctures.

We analyzed plasma melatonin levels in different groups of preterm newborns without hypoxia and their relationship with several perinatal variables like gestational age or neonatal pain. Prospective cohort study of preterm newborns (PTNB) without perinatal hypoxia, Apgar > 6 at 5 min, and oxygen needs on the third day of life. We compared melatonin levels at day 3 of life in different groups of non-hypoxic preterm infants (Student's t-tests, Mann-Whitney U, and chi2) and analyzed the relationship of melatonin with GA, birth weight, neonatal pain (Premature Infant Pain Profile (PIPP) scale), caffeine treatment, parenteral nutrition, or the development of free radical diseases (correlation study, linear regression) and factors associated with moderate/intense pain and free radical diseases (logistic regression analysis). Sixty-one preterm infants with gestational age (GA) of 30.7 ± 2.0 weeks with no oxygen requirements at day 3 of life were studied with plasma melatonin levels of 33.8 ± 12.01 pg/ml. Preterm infants weighing < 1250 g at birth had lower plasma melatonin levels (p = 0.05). Preterm infants with moderate or severe pain (PPIPP > 5) have lower melatonin levels (p = 0.01), and being preterm with PIPP > 5 is associated with lower plasma melatonin levels (p = 0.03). Being very preterm (GA < 32 GS), having low weight for gestational age (LWGA), receiving caffeine treatment, or requiring parenteral nutrition did not modify melatonin levels in non-hypoxic preterm infants (p = NS). Melatonin on day 3 of life in non-hypoxic preterm infants is not associated with later development of free radical diseases (BPD, sepsis, ROP, HIV, NEC). Conclusion: We observed that preterm infants with moderate to severe pain have lower melatonin levels. These findings are relevant because they reinforce the findings of other authors that melatonin supplementation decreases pain and oxidative stress in painful procedures in premature infants. Further studies are needed to evaluate whether melatonin could be used as an analgesic in painful procedures in preterm infants. Trial registration: Trial registration was not required since this was an observational study. What Is Known: • Melatonin is a potent antioxidant and free radical scavenger in newborns under stress conditions: hypoxia, acidosis, hypotension, painful procedures, or parenteral nutrition. • Pain stimulates the production of melatonin. • Various studies conclude that melatonin administration decreases pain during the neonatal period. What Is New: • Non-hypoxic preterm infants with moderate to severe pain (PIPP>5) have lower levels of melatonin. • Administration of caffeine and treatment with parenteral nutrition do not modify melatonin levels in non-hypoxic preterm infants.

Objectives: Cerebral magnetic resonance imaging (cMRI) at term-equivalent age (TEA) can detect brain injury (BI) associated with adverse neurological outcomes in preterm infants. This study aimed to assess BI incidences in a large, consecutive cohort of preterm infants born < 32 weeks of gestation, the comparison between very (VPT, ≥ 28 + 0 to < 32 + 0 weeks of gestation) and extremely preterm infants (EPT, < 28 + 0 weeks of gestation) and across weeks of gestation. Methods: We retrospectively analyzed cMRIs at TEA of VPT and EPT infants born at a large tertiary center (2009–2018). We recorded and compared the incidences of BI, severe BI, intraventricular hemorrhage (IVH), periventricular hemorrhagic infarction (PVHI), cerebellar hemorrhage (CBH), cystic periventricular leukomalacia (cPVL), and punctate white matter lesions (PWML) between VPTs, EPTs, and across weeks of gestation. Results: We included 507 preterm infants (VPT, 335/507 (66.1%); EPT, 172/507 (33.9%); mean gestational age (GA), 28 + 2 weeks (SD 2 + 2 weeks); male, 52.1%). BIs were found in 48.3% of the preterm infants (severe BI, 12.0%) and increased with decreasing GA. IVH, PVHI, CBH, cPVL, and PWML were seen in 16.8%, 0.8%, 10.5%, 3.4%, and 18.1%, respectively. EPT vs. VPT infants suffered more frequently from BI (59.3% vs. 42.7%, p < 0.001), severe BI (18.6% vs. 8.7%, p = 0.001), IVH (31.9% vs. 9.0%, p < 0.001), and CBH (18.0% vs. 6.6%, p < 0.001). Conclusion: Brain injuries are common cMRI findings among preterm infants with a higher incidence of EPT compared to VPT infants. These results may serve as reference values for clinical management and research. Clinical relevance statement: Our results with regard to gestational age might provide valuable clinical insights, serving as a key reference for parental advice, structured follow-up planning, and enhancing research and management within the Neonatal Intensive Care Unit. Key Points: • Brain injury is a common cMRI finding in preterm infants seen in 48.3% individuals. • Extremely preterm compared to very preterm infants have higher brain injury incidences driven by brain injuries such as intraventricular and cerebellar hemorrhage. • Reference incidence values are crucial for parental advice and structured follow-up planning.

Background: In the neonatal intensive care unit (NICU), elevated noise negatively impacts the neurodevelopmental environment, interrupts sleep, and can affect brain development in neonates. The American Academy of Pediatrics recommends that noise levels in the NICU should not exceed 45 dB. Purpose: The project aims were to: (1) decrease average noise level by 10% from baseline and (2) decrease exposure to severe noise (>65 dB) to <5% of the time. Methods: This quality improvement project was conducted during 2021-2022 as a pre/post observational design in a Level IV NICU in New York City. We monitored sound levels for 20-24 h, 5 d/wk. Quality improvement interventions included: novel approaches to staff education, visual cues for when noise thresholds were exceeded, parent education, including access to personal decibel meters, technical improvements to vital sign monitors and entry doors, and defined quiet times (HUSH) for 2 h each 12-hour shift. Results: Education efforts and technical improvements successfully reduced median noise levels within the stepdown unit (P < .001), though not in the acute care NICU. In contrast, the implementation of 2-hour periods of enforced "quiet time" every 12 h effectively reduced both median noise levels and the incidence of severe noise (>65 dB) in both locations. Implications for practice and research: The HUSH strategy may be a sustainable way to decrease noise in the NICU. Future projects should prioritize education and dedicated quiet times to align with recommended standards, while research should explore the long-term developmental impacts of excessive noise levels on neonatal growth.

- Abstract
This study aimed to evaluate the incidence and risk factors associated with refeeding syndrome (RFS) in preterm infants (≤32 weeks gestational age) during their first week of life. Infants (gestational age ≤ 32 weeks; birth weight < 1500 g) who were admitted to the neonatal intensive care unit (NICU), level III, and received parenteral nutrition between January 2015 and April 2024 were retrospectively evaluated. Modified log-Poisson regression with generalized linear models and a robust variance estimator was applied to adjust the relative risk of risk factors. Of the 760 infants identified, 289 (38%) developed RFS. In the multivariable regression analysis, male, intraventricular hemorrhage (IVH), and sodium phosphate significantly affected RFS. Male infants had significantly increased RFS risk (aRR1.31; 95% CI 1.08–1.59). The RFS risk was significantly higher in infants with IVH (aRR 1.71; 95% CI 1.27–2.13). However, infants who received higher sodium phosphate in their first week of life had significantly lower RFS risk (aRR 0.67; 95% 0.47–0.98). This study revealed a notable incidence of RFS among preterm infants aged ≤32 gestational weeks, with sex, IVH, and low sodium phosphate as significant risk factors. Refined RFS diagnostic criteria and targeted interventions are needed for optimal management. [ABSTRACT FROM AUTHOR]

Introduction: Human cytomegalovirus (HCMV) is the most common viral infection seen in newborns. The major route of transmission for acquired human cytomegalovirus infection is breast milk from mothers who are HCMV seropositive to the infants. Thus, a rapid, economical, and simple method to perform HCMV test in breast milk is crucial and necessary for preventing acquired HCMV infection, especially in underdeveloped regions with limited laboratory resources. Methods: In this study, an effective technique for the detection of HCMV was constructed by combining multienzyme isothermal rapid amplification (MIRA) and lateral flow chromatography strip (LFD). Primers for the conserved HCMV sequence UL83 were utilized for MIRA-LFD testing. Results: Our results showed that the entire MIRA reaction could be completed in 12 minutes at 37°C, and LFD outcomes could be observed visibly after 10 minutes. The detection sensitivity of this method reached 50 copy/ml. Samples of breast milk were examined to compare MIRA-LFD and conventional qPCR. The accuracy of MIRA-LFD was 100%. Discussion: The straightforward, rapid, economic features of the test can provide the significant advantages for the prevention of breast milk-acquired cytomegalovirus infection, particularly in resource-limited locations with high seroprevalence of cytomegalovirus.

AbstractPreterm infants, often characterized by lower birth weights and underdeveloped physiologies, necessitate specialized nutritional care. While breast milk stands as the ideal nutritional source, offering substantial energy through its fatty acid content to support the infants’ growth and developmental needs, its usage might not always be feasible. Fatty acids in breast milk are critical for the development of these infants. In scenarios where breast milk is not an option, formula feeding becomes a necessary alternative. Thus, a comprehensive understanding of the fatty acid profiles in both breast milk and formulas is crucial for addressing the distinct nutritional requirements of preterm infants. This paper aims to summarize the effects of lipid composition, structure, and positioning in breast milk and formula on the growth and development of preterm infants. Furthermore, it explores recent advancements in the use of novel structural lipids in formulas, laying the groundwork for future innovations in formula design specifically catered to the needs of preterm infants.

Providing adequate nutrition in the management of preterm infants has been challenging. The objective of this secondary analysis of data from the randomized trial comparing “less invasive surfactant therapy (LISA) with InSurE method of surfactant administration” is to demonstrate the feasibility of early total enteral feeding (ETEF) in hemodynamically stable preterm neonates on respiratory support and to examine the factors associated with failure of ETEF.Introduction: Secondary analysis of a randomized controlled trial comparing “LISA versus InSurE among preterm infants between 26 and 34 weeks of gestation” enrolled 150 infants with 117 being hemodynamically stable. ETEF without any parenteral supplementation was started on day 1 of life using the mother’s own milk (MoM) or donor human milk (<32 weeks of GA) and MoM or preterm formula (33–34 weeks of GA). The data were analyzed to assess the proportion of babies developing feed intolerance and/or necrotizing enterocolitis (NEC) and factors associated with failure of ETEF. All Infants were assessed for the day of attainment of full enteral feeding defined as receiving and tolerating 150 mL/kg of enteral feeds per day.Methods: Out of these 117 babies, 102 tolerated ETEF, and 15 had one or more episodes of FI requiring total parenteral nutrition, but none developed NEC till discharge or death. On the assessment of possible factors associated with ETEF failure, there were no differences in baseline characteristics but statistically significantly increased incidence of culture-positive sepsis as well as the requirement of antibiotic therapy for possible sepsis (early as well as late-onset sepsis) in babies with failure of ETEF. The babies who tolerated ETEF achieved full enteral feeding (150 mL/kg/day) significantly earlier (5.48 ± 1.1 days) compared to those with ETEF failure (7 ± 3.4 days) (Results: p 0.001). The time to regain birth weight was earlier in the ETEF group without significant differences in growth parameters. There was also a reduction in the duration of hospital stay in babies who tolerated ETEF, but both these results were not statistically significant. ETEF is feasible in preterm neonates with respiratory distress syndrome who are on respiratory support. It resulted in earlier attainment of full enteral feeds and decreased the incidence of sepsis with reduced antibiotic usage. The objective of this secondary analysis of data from the randomized trial comparing less invasive surfactant therapy (LISA) with InSurE method of surfactant administration among preterm infants with respiratory distress syndrome (RDS) is to demonstrate the feasibility of ETEF in hemodynamically stable preterm neonates on respiratory support.In this randomized control trial comparing LISA versus InSurE among preterm infants with RDS between 26 and 34 weeks of gestation, 150 infants were enrolled with 117 being hemodynamically stable. In 33 patients, early total enteral feeding could not be started due to various reasons – 7 babies had absence/reversal of end-diastolic flow (A/REDF) on antenatal Doppler, 15 babies had shock and required inotropic support on day 1 of life, 8 babies had higher ventilatory settings at the time of admission, and in the 3 babies, the abdomen was not soft to start total enteral feeding. Full-volume enteral feeding without any parenteral supplementation was started on day 1 of life using the mother’s own milk (MoM) or donor human milk (≤32 weeks of GA) and MoM or preterm formula (33–34 weeks of GA). The data were analyzed to assess the proportion of babies developing feed intolerance and/or NEC and factors associated with failure of ETEF. Out of these 117 babies, 102 tolerated ETEF, and 15 had one or more episodes of FI requiring parenteral supplementation, but none developed NEC. There was a statistically significantly increased incidence of culture-positive sepsis as well as the requirement of antibiotic therapy for possible sepsis in babies with failure of ETEF. There was no difference in the morbidities noted such as intraventricular hemorrhage grade 2 or more, patent ductus arteriosus requiring medical or surgical management, retinopathy of prematurity requiring treatment, and NEC stage II or more. Our study suggests that hemodynamically stable preterm infants with RDS on respiratory support can be successfully fed with exclusive enteral feeds started immediately post-birth. ETEF results in early attainment of full feeding and reduces the incidence of sepsis and the duration of hospital stay without increasing the risk of NEC.

Background: Necrotizing enterocolitis (NEC) is a life-threatening disease that affects premature infants. However, the role of inflammatory biomarkers in identifying surgical/death NEC without pneumoperitoneum remains elusive. Purpose: We aimed to verify the value of platelet-to-lymphocyte ratio (PLR) and the combination of white blood cell (WBC), absolute neutrophil count (ANC), absolute lymphocyte count (ALC), neutrophil lymphocyte ratio (NLR), PLR, C reactive protein (CRP) and procalcitonin (PCT) in predicting the severity of NEC, and to construct a model to differ surgically NEC from non-surgically NEC. Methods: A retrospective analysis was performed on 191 premature infants with NEC. Based on the inclusion and exclusion criteria, 90 infants with Stage II and IIIA NEC were enrolled in this study, including surgical/death NEC (n = 38) and medical NEC (n = 52). The values of inflammatory biomarkers were collected within 24 h of onset. Results: The univariate analysis revealed that the values of WBC (p = 0.040), ANC (p = 0.048), PLR (p = 0.009), CRP (p = 0.016) and PCT (p < 0.01) in surgical/death NEC cohort were significantly higher than medical NEC cohort. Binary multivariate logistic regression analysis indicates that ANC, PLR, CRP, and PCT are capable of distinguishing infants with surgical/death NEC, and the AUC of the regression equation was 0.79 (95% CI 0.64–0.89; sensitivity 0.63; specificity 0.88), suggesting the equation has a good discrimination. Implications for practice and research: Elevated PLR is associated with severe inflammation in surgical/death NEC patients. The prediction modelling of combination of ANC, PLR, CRP and PCT can differentiate surgical/death NEC from infants with medical NEC, which may improve risk awareness and facilitate effective communication between nurses and clinicians. However, multicentre research is needed to verify these findings for better clinical management of NEC. [ABSTRACT FROM AUTHOR]

Objective The aim of the study is to determine clinical correlates of moderate to severe bronchopulmonary dysplasia (BPD) in preterm infants following surgical necrotizing enterocolitis (NEC). Study Design This is a retrospective, single-center cohort study comparing patients with moderate to severe BPD to patients with non/mild BPD among surgical NEC infants. BPD was defined by NIH 2001 consensus definition. Results Of 92 consecutive neonates with surgical NEC, 77% (71/92) had moderate/severe BPD and 22% (21/92) had non/mild BPD. The patent ductus arteriosus (PDA) was significantly higher in those developing moderate/severe BPD (67.6% [48/71]) than non/mild BPD (28.6% [6/21]; p = 0.001). Postoperatively, infants with moderate/severe BPD had more severe acute kidney injury (AKI; 67.6 [48/71] vs. 28.6% [6/21]; p = 0.001), were intubated longer (40.5 [interquartile (IQR): 12, 59] vs. 6 days [IQR: 2, 13]; p <0.001), received more parenteral nutrition (109 [IQR: 77, 147] vs. 55 days [IQR: 19, 70]; p <0.001), developed higher surgical morbidity (46.5 [33/71] vs. 14.3% [3/21]; p = 0.008), had more intestinal failure (62.5 vs. 13.3%; p <0.001), required a longer hospital stay (161 [IQR: 112, 186] vs. 64 days [IQR: 20, 91]; p <0.001), and were more likely to need home oxygen. In a multivariable analysis, lower birth weight (OR = 0.3, [95% confidence interval (CI): 0.1–0.5]; p = 0.001), PDA (OR = 10.3, [95% CI: 1.6–65.4]; p = 0.014), and longer parenteral nutritional days (OR = 8.8; [95% CI: 2.0–43.0]; p = 0.005) were significantly and independently associated with higher odds of moderate/severe versus non-/mild BPD. Conclusion Development of moderate/severe BPD occurred in the majority of preterm infants with surgical NEC in this consecutive series. Preterm infants with moderate/severe BPD were more likely to have a PDA before NEC. Development of moderate/severe BPD was associated with significantly greater burden and duration of postoperative morbidity following surgical NEC. Identifying surgical NEC infants at increased risk of moderate/severe BPD and developing lung protection strategies may improve surgical NEC outcomes. Key Points Three-fourths of preterm infants experienced severe lung injury following surgical NEC. The infants with severe moderate/severe BPD were most likely associated with greater duration of postoperative morbidity. There is need to understand and develop lung protective strategies in infants with surgical NEC. [ABSTRACT FROM AUTHOR]

Background: To investigate the relationship between cord blood levels of Angiopoietin-1 (Ang-1) and S-endoglin (sCD105) and bronchopulmonary dysplasia (BPD) in preterm infants. Methods: Sixty-one preterm infants admitted to the neonatal intensive care unit of the study hospital between July 2021 and September 2022 were included. Cord blood was collected after the birth of premature infants. Ang-1 and sCD105 levels were quantified using the vascular endothelial growth factor enzyme-linked immunosorbent assay. Preterm infants were divided into BPD and non-BPD groups, and differences in Ang-1 and sCD105 levels between the two groups were compared. A binary logistic model was used to assess the association between low and high levels Ang-1 and BPD in preterm infants. Results: In the study, there were 20 preterm infants with BPD (32.8%) and 41 preterm infants with non-BPD (67.2%). Ang-1 concentration levels were lower in the BPD group than in the non-BPD group (7105.43 (5617.01–8523.00) pg/ml vs. 10488.03 (7946.19–15962.77) pg/ml, P = 0.027). However, the sCD105 concentration levels were not significantly different between the BPD and non-BPD groups (P = 0.246). A median Ang-1 concentration of 8800.40 pg/ml was calculated. Logistic regression analysis showed that after adjusting for gestational age, birth weight, and maternal prenatal steroid hormone application, the odds ratio (OR) was 8.577 for the risk of BPD in preterm infants with Ang-1 concentrations of ≤ 8800.40 pg/ml compared to those with Ang-1 concentrations of > 8800.40 pg/ml (OR: 8.577, 95% confidence interval: 1.265–58.155, P = 0.028). Conclusion: Our study indicated that Ang-1 levels in the cord blood of preterm infants may be associated the risk of BPD. In the future, we will continue to conduct study with large samples.

Introduction: Less invasive surfactant application (LISA) is associated with improved short-term outcomes in preterm infants. Data on LISA eligibility and success for infants <28 weeks of gestation are lacking. Methods: Preterm infants <28 weeks of gestation who were born and actively treated in our tertiary care center in 2018 were included in the retrospective study. We assessed baseline characteristics, delivery room (DR) management, LISA success and complications, and short-term outcome. Results: In total, 57 infants received LISA in the DR. LISA eligibility was 73% at 22 weeks, 88% at 23 weeks, and >90% at gestational ages >24 weeks. LISA was successful in 63% of infants. LISA failure was associated with increased risk for high-grade IVH (OR 17.88), death (OR 10.94), and a reduced chance for survival without complications (OR 8.75). Conclusion: Our report justifies LISA as a mode for surfactant application in preterm infants. It contributes to the call for studies to define risk factors for LISA failure. [ABSTRACT FROM AUTHOR]

Introduction: Three widely referenced growth curves classify infant birth anthropometric measurements as small (SGA), appropriate (AGA), or large (LGA) for gestational age (GA) differently. We assessed how these differences in assignment affect the identification and prediction of neonatal intensive care unit (NICU) mortality risk in US preterm infants. Methods: Birth data of infants admitted to NICUs from the Pediatrix Clinical Data Warehouse (2013–2018) were analyzed. Birth weight, length, and head circumference of 46,724 singleton infants (24–32 weeks GA) were classified as SGA, AGA, or LGA using the Olsen, Fenton, and INTERGROWTH-21st curves. NICU mortality risk based on birth size classification was analyzed using unadjusted and adjusted logistic regression stratified by GA. Results: Odds of mortality were increased with SGA classification at all GAs, size measurements, and curve sets, compared with AGA infants. LGA classification for weight was associated with lower mortality risk at 24 weeks GA and higher risk at 30 weeks GA. Odds of mortality did not differ significantly across curve sets. Classification of size at birth alone had relatively low predictive ability to identify mortality risk, with unadjusted AUCs near 0.5 for all analyses. Conclusion: There were no significant differences across curve sets in predicting mortality. Classification of size at birth is a relatively imprecise method to identify infants at risk for NICU mortality. [ABSTRACT FROM AUTHOR]

Bronchopulmonary dysplasia (BPD) affects the microstructure of white matter in preterm infants, but its influence on the changes of the brain structural network has not been elaborated. This study aims to investigate the connectivity characteristics of the brain structural network of BPD by using diffusion tensor imaging. Thirty-three infants with BPD and 26 infants without BPD were enrolled in this study. Brain structural networks were constructed utilizing automated anatomic labeling mapping by tracing the fibers between each pair of regions in individual space. We calculated network metrics such as global efficiency, local efficiency, clustering coefficients, characteristic path length, and small-worldness. Then we compared the network metrics of these infants with those of 57 healthy term infants of comparable postmenstrual age at magnetic resonance imaging scan. Finally, network-based statistics was used to analyze the differences in brain network connectivity between the groups with and without BPD. Preterm infants with BPD had higher local efficiency and clustering coefficient, lower global efficiency, and longer characteristic path length. Also, preterm infants with BPD had decreased strength of limbic connections mainly in four brain regions: the left lingual gyrus, the left calcarine fissure and surrounding cortex, the right parahippocampal gyrus, and the left precuneus. Our findings suggest that preterm infants with BPD have lower network integration and higher segregation at term-equivalent age, which may reflect a compensatory mechanism. In addition, BPD affects brain regions involved in visual as well as cognitive functions; these findings provide a new approach to diagnose potential brain damage in preterm infants with BPD.

Purpose: To investigate the effect of amoxicillin-clavulanate potassium and potential factors influencing umbilical cord separation time in preterm infants. Methods: A total of 151 preterm infants admitted to the Neonatology Department, First Affiliated Hospital of Anhui Medical University, Hefei, China, from November 2020 to June 2021 were selected. Preterm infants were randomly divided into control and study groups. Control group received 2 % povidone-iodine and 75 % ethanol application, followed by gentle pressure with a cotton swab while the study group received amoxicillin-clavulanate potassium applied to the umbilical cord while shaking. The management interventions were stopped after umbilical cord separation in preterm infants, and the difference in umbilical cord separation time between the two groups was compared. Factors associated with preterm birth conditions, hospitalization, and maternal health were identified by univariate and multivariate logistic regression analyses. Results: The number of cases with umbilical cord separation time > 14 days was significantly higher in the study group compared to control group (p < 0.05). The average umbilical cord separation time in the study group was significantly lower compared to control group (p < 0.05). Univariate analysis revealed that incubator residence time significantly affects umbilical cord separation time in preterm infants (p < 0.05). Logistic multivariate regression analysis identified incubator residence time as the main factor influencing umbilical cord separation time in preterm infants. Conclusion: The use of amoxicillin-clavulanate potassium shortens umbilical cord separation time, and incubator residence time is the major factor influencing umbilical cord separation in preterm infants. Further studies should expand the study scale and increase the number of samples used. [ABSTRACT FROM AUTHOR]

PREMATURE infants , *BRONCHOPULMONARY dysplasia , *VERY low birth weight , *VIRUS diseases , *MENSTRUATION disorders - Abstract
Bronchopulmonary dysplasia (BPD) is the most common serious complication of very preterm infants (VPI) or very low birth weight (VLBW) infants. Studies implicate viral infections in etiopathogenesis. The aim of this study was to summarize the relationship between viral infections and BPD through a systematic review and meta-analysis. We searched PubMed, Embase, the Web of Science Core Collection, and the Cochrane Database on December 19, 2023. We included observational studies that examined the association between viral infections and BPD in preterm infants. We extracted data on study methods, participant characteristics, exposure assessment, and outcome measures. We assessed study risk of bias using the Newcastle-Ottawa Scale (NOS). We included 17 and 15 studies in the qualitative review and meta-analysis, respectively. The meta-analysis showed a significant association between viral infection and BPD diagnosed at 36 weeks postmenstrual age (odds ratio (OR): 2.42, 95% confidence interval: 1.89–3.09, 13 studies, very low certainty of evidence). In a subgroup analysis of specific viruses, cytomegalovirus (CMV) proved to be significantly associated with BPD diagnosed at 36 weeks postmenstrual age (OR: 2.34, 95% confidence interval: 1.80–3.05, 11 studies). We did not find an association between viral infection and BPD diagnosed on the 28th day of life, probably due to the small sample size of the included prospective studies. Conclusion: Viral infections, especially CMV, are associated with an increased risk of BPD in preterm infants. Methodologically reliable prospective studies with large samples are needed to validate our conclusions, and high-quality randomized controlled studies are needed to explore the effect of prevention or treatment of viral infections on the incidence of BPD. What is Known: • Studies have attempted to identify viral infections and bronchopulmonary dysplasia in preterm infants; however, results have been inconsistent. What is New: • Systematic demonstration that viral infections, particularly cytomegalovirus, are positively associated with bronchopulmonary dysplasia diagnosed in preterm infants at the 36th week of postmenstrual age. • The importance of screening for viral infections in preterm infants, especially cytomegalovirus. More high-quality studies should be produced in the future to investigate the causal relationship between viral infections and bronchopulmonary dysplasia. [ABSTRACT FROM AUTHOR]

Nutritional intake could influence the blood glucose profile during early life of preterm infants. We investigated the impact of macronutrient intake on glycemic homeostasis using continuous glucose monitoring (CGM). We analyzed macronutrient intake in infants born ≤ 32 weeks gestational age (GA) and/or with birth weight ≤ 1500 g. CGM was started within 48 h of birth and maintained for 5 days. Mild and severe hypoglycemia were defined as sensor glucose (SG) < 72 mg/dL and <47 mg/dL, respectively, while mild and severe hyperglycemia were SG > 144 mg/dL and >180 mg/dL. Data from 30 participants were included (age 29.9 weeks (29.1; 31.2), birthweight 1230.5 g (1040.0; 1458.6)). A reduced time in mild hypoglycemia was associated to higher amino acids intake (p = 0.011) while increased exposure to hyperglycemia was observed in the presence of higher lipids intake (p = 0.031). The birthweight was the strongest predictor of neonatal glucose profile with an inverse relationship between the time spent in hyperglycemia and birthweight (p = 0.007). Conclusions: Macronutrient intakes influence neonatal glucose profile as described by continuous glucose monitoring. CGM might contribute to adjust nutritional intakes in preterm infants. What is Known: • Parenteral nutrition may affect glucose profile during the first days of life of preterm infants. What is New: • Continuous glucose monitoring describes the relationship between daily parenteral nutrient intakes and time spent in hypo and hyperglycemic ranges. [ABSTRACT FROM AUTHOR]

Objective Preterm delivery with the admission of a child in the neonatal intensive care unit (NICU) is extremely challenging for parents. Being separated from the baby and seeing her infant feeling pain and being sick together with the complexity of the NICU environment, the mother experiences great anxiety, fear, and stress. The purpose of the study was to assess NICU-related stress and to identify maternal and infant factors associated with increased stress in mothers of preterm infants. Study Design The maternal stress level was assessed in 122 mothers of preterm infants using the Parental Stressor Scale: NICU (PSS: NICU) in which items were distributed in three subscales as follows: Sights and Sounds of NICU—subscale 1 (S1), Infant Appearance and Behavior—S2, and Parental Role Alteration—S3. Results Maternal total PSS: NICU score was 3.46 ± 0.71. Parenteral Role Alteration was the most stressful (4.20 ± 0.79) followed by Infant Appearance and Behavior (3.51 ± 0.91) and Sights and Sounds subscale (2.28 ± 0.95); p(S1–S2) < 0.001, p(S1–S3) < 0.001, and p(S2–S3) < 0.001. Total PSS: NICU and Infant Appearance and Behavior scores correlated positively with maternal age (r = 0.189; p = 0.040 and r = 0.204; p = 0.027, respectively) and duration of NICU treatment (r = 0.188; p = 0.044 and r = 0.190; p = 0.042). More visits in NICU by a mother were associated with a lower PSS: NICU score (p = 0.049) and neonatal seizures and invasive ventilation in infants were associated with higher stress scores (p = 0.007 and p = 0.042). Conclusion Mothers of preterm infants admitted in the NICU experience significant stress which is correlated with maternal age and NICU treatment duration and is associated with frequency of NICU visits, presence of neonatal seizures, and need for ventilator support. Parental role alteration is the greatest stressor followed by Infant Appearance and Behavior and NICU-surrounding stressor factors which show the need for interventions and counseling focused on mothers' role, their involvement in infant's care, and thus, family-centered care implementation. Key Points Mothers of preterm infants experience significant stress. Parental role alteration is the greatest maternal stressor. Maternal stress is correlated with age and NICU duration, and is associated with the frequency of NICU visits and infant's health status [ABSTRACT FROM AUTHOR]

Aim: Apnoea of prematurity requires prompt intervention to prevent long‐term adverse outcomes, but specific recommendations about the stimulation approach are lacking. Our study investigated the modalities of tactile stimulation for apnoea of prematurity in different settings. Methods: In this multi‐country observational prospective study, nurses and physicians of the neonatal intensive care units were asked to perform a tactile stimulation on a preterm neonatal manikin simulating an apnoea. Features of the stimulation (body location and hand movements) and source of learning (training course or clinical practice) were collected. Results: Overall, 112 healthcare providers from five hospitals participated in the study. During the stimulation, the most frequent location were feet (72%) and back (61%), while the most frequent techniques were rubbing (64%) and massaging (43%). Stimulation modalities different among participants according to their hospitals and their source of learning of the stimulation procedures. Conclusion: There was a large heterogeneity in stimulation approaches adopted by healthcare providers to counteract apnoea in a simulated preterm infant. This finding may be partially explained by the lack of specific guidelines and was influenced by the source of learning for tactile stimulation. [ABSTRACT FROM AUTHOR]

Aim: The supine sleeping position in the prevention of sudden infant death syndrome in preterm infants is poorly understood. We aimed to investigate the effect of sleep posture on cardiorespiratory parameters and movement patterns in preterm infants close to discharge. Methods: This observational study included neonates born in 2022 at the University Hospital Schleswig‐Holstein, Lübeck, Germany. Motion sensor data, heart rate, respiratory rate and oxygen saturation were recorded for infants with postconceptional age 35–37 weeks during sleep in the prone and supine positions. Results: We recorded data from 50 infants, born at 31 (24–35) weeks of gestation (mean(range)), aged 5.2 ± 3.7 weeks (mean ± SD), of whom 48% were female. Five typical movement patterns were identified. In the prone position, the percentage of calm, regular breathing was higher and active movement was less frequent when compared to the supine position. The percentage of calm irregular breathing, number of apnoeas, bradycardias, desaturations and vital sign changes were not influenced by position. Conclusion: The prone position seems to be associated with a higher arousal threshold. The supine position appears advantageous for escape from life‐threatening situations such as sudden infant death syndrome. [ABSTRACT FROM AUTHOR]

Engaging parents in musical interactions through singing to their preterm infants is becoming a primary music therapy (MT) approach within the neonatal context. Parents describe their positive experiences during MT in the NICU and post-discharge. A recent longitudinal study offered families resource-oriented music therapy services from birth to home. Based on an interpretive phenomenological analysis of parental experiences of MT in the LongSTEP trial, I posit musical agency as a theoretical framework for understanding the processes that are enabled during MT with families of preterm infants from birth to home. I explore the concept of musical agency through social and psychotherapy theories and through examples taken from MT sessions and interviews. I illustrate how the guiding principles of a resource-oriented approach to MT correspond with enhancing musical agency. Musical agency is every person's ability to use music for personal and social needs. Musical agency is released and interchanged through musical interactions between parents and their preterm infants during MT. Resource-oriented principles in MT may offer music therapists ways to empower clients' musical agency. Musical agency may increase other forms of agency and support parents to connect to themselves and their preterm infants, depending on parental appropriation of music's affordances. Embracing the framework of agency calls for music therapists to be aware of power dynamics and shift to a collaborative approach within MT sessions, aligning with a resource-oriented approach.

Objectives Premature infants (born before 37 weeks of gestational age) frequently experience feeding difficulties due to underdeveloped oral motor skills and poor chewing, swallowing, and breathing coordination. In order to improve oral feeding efficiency in these infants, Oral-Motor Stimulation (OMS) has been used in various studies. This systematic review study will aim to assess the effectiveness of OMS for oral feeding in preterm infants. Materials & Methods The authors will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. They will conduct a search in electronic databases, including PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials in The Cochrane Library (CENTRAL), Medline via PubMed, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) for nursing and related healthcare texts without language restrictions from the first month of 1991 to the fifth month of 2024 to achieve the study objectives. All Randomized Controlled Clinical Trials (RCT) examining the effect of OMS on oral feeding in preterm infants will be included in this study. Results The primary outcome of this systematic review will be oral feeding, and the secondary outcomes will include duration of hospitalization, weight gain, and feeding efficiency. Two independent reviewers will select and extract data for the study. The Cochrane Risk of Bias Tool (RoB2) will be used to evaluate potential biases in the study. Publication bias will be evaluated using funnel plots, Begg's, and Egger's tests. The degree of heterogeneity among the studies will be assessed using the I2 statistic and the χ² test. Analyses of subgroups will also be carried out. All meta-analyses will be conducted using Stata V.14. Conclusion This systematic review protocol for preterm infants will aim to promote evidencebased decision-making and support the development of clinical practice guidelines in preterm feeding.

- Abstract
Parenteral nutrition (PN) is recognized as a complex high-risk therapy. Its practice is highly variable and frequently suboptimal in pediatric patients. Optimizing care requires evidence, consensus-based guidelines, audits of practice, and standardized strategies. Several pediatric scientific organizations, expert panels, and authorities have recently recommended that standardized PN should generally be used over individualized PN in the majority of pediatric patients including very low birth weight premature infants. In addition, PN admixtures produced and validated by a suitably qualified institution are recommended over locally produced PN. Licensed multi chamber bags are standardized PN bags that comply with Good Manufacturing Practice and high-quality standards for the finished product in the frame of their full manufacturing license. The purpose of this article is to review the practical aspects of PN and the evidence for using such multi-chamber bags in pediatric patients. It highlights the safety characteristics and the limitations of the different PN practices and provides some guidance for ensuring safe and efficient therapy in pediatric patients.

Music therapy (MT) is proposed to enrich the acoustic environment of very preterm infants (VPT) on the neonatal intensive care unit during a vulnerable period of brain development. The objective of this study was to investigate the effect of MT on the white matter (WM) microstructure. It is hypothesized that MT affects WM integrity in VPT. Randomized controlled trial enrolling infants born <32 weeks' gestation. Infants were randomized to MT or standard care. Live MT was provided twice weekly from the second postnatal week onwards by a trained music therapist. At term equivalent age, participants underwent a cranial magnetic resonance imaging scan including sequences for diffusion tensor imaging analysis. Differences in WM microstructure were assessed using tract based spatial statistics with fractional anisotropy. Of 80 infants enrolled, 42 were eligible for diffusion tensor imaging analysis (MT: n = 22, standard care: n = 20). While primary tract based spatial statistics analysis revealed no significant differences between groups, post hoc analysis with uncorrected p -values and a significance threshold of p < 0.01 revealed significant fractional anisotropy differences in several WM tracts including the bilateral superior longitudinal fasciculus, the left forceps minor and left fasciculus uncinatus, the corpus callosum, the left external capsule, and the right corticospinal tract. Post hoc analysis results suggest an effect of MT on WM integrity in VPT. Larger studies including long-term outcome are necessary to confirm these effects of MT on WM microstructure and to assess its impact on clinical neurodevelopment. Clinical trial number DRKS00025753. • Music therapy (MT) has positive effects on preterm infants (e.g.vital parameters) • The effect of MT on neurodevelopment remains unclear • Randomized controlled trial analyzing its effect on white matter microstructure • Diffusion tensor imaging data was used to analyze its effect on cerebral white matter • Results increase evidence of effects of MT on the white matter microstructure [ABSTRACT FROM AUTHOR]

Breast milk is optimal for both term and preterm infants as it provides essential nutrition and immunity. However, mothers of preterm infants often have insufficient milk supply, resulting in low breastfeeding rates, including in Thailand, where this quasi-experimental study was undertaken. We investigated the effects of an early breastfeeding education and proactive telephone support program, including early breastfeeding education and proactive telephone support. This included breastfeeding outcomes, including total breast milk volume, duration of exclusive breastfeeding, and exclusive breastfeeding rates at discharge and three months post-discharge in mothers of preterm infants. The participants included 57 mother-infant dyads and their families. The participants were assigned to either the control group (n = 28) receiving routine care or the experimental group (n = 29) receiving the intervention program. The assignment was done using purposive sampling and matching the number of pregnancies and gestational age between the two groups. Data were collected using the Demographic Characteristics Questionnaire, the Breast Milk Expressing Record Form, the Oral Care with Breast Milk Record Form, and the Breastfeeding Practice and Problems Record Form. Data analysis was performed using the chi-square test, Mann-Whitney U test, independent t-test, and descriptive statistics. The results indicated that, after receiving the program, the total breast milk volume from day 1 to day 7 and the duration of exclusive breastfeeding in the experimental group were significantly higher and longer than in the control group. At discharge, the rate of exclusive breastfeeding in the experimental group was higher than that of the control group but with no statistical difference. However, the experimental group had a significantly higher exclusive breastfeeding rate at three months than the control group. This study confirmed the program's effectiveness in increasing the exclusive breastfeeding rate at three months. Nurses can integrate this program to promote breastfeeding as a critical component of preterm infant care. Still, a long-term follow-up study requires comprehensive testing of its effectiveness.

Objectives: Although recent discoveries regarding the biomarkers of newborn screening (NBS) programs by tandem mass spectrometry (MS/MS) highlight the critical need to establish reference intervals (RIs) specifically for preterm infants, no such RIs has been formally published yet. This study addressed the gap by offering a comprehensive set of reference intervals (RIs) for preterm neonates, and illustrating the dynamic changes of each biomarker with age. Design and methods: The NBS data of 199,693 preterm newborns (< 37 weeks of gestation) who met the inclusion and exclusion criteria from the NNSCP database were included in study analysis. The birth weight stratified dynamic trend of each biomarker were captured by their concentrations over age. Reference partitions were determined by the method of Harris and Boyd. RIs, corresponding to the 2.5th and 97.5th percentiles, as well as the 0.5th, 25th, 50th, 75th and 99.5th percentiles were calculated using a non-parametric rank approach. Results: Increasing birth weight is associated with an elevation in the levels of arginine, citrulline, glycine, leucine and isobarics, methionine, ornithine, phenylalanine, and valine, whereas the levels of alanine, proline and tyrosine decrease. Additionally, two short-chain acylcarnitines (butyrylcarnitine + isobutyrylcarnitine and isovalerylcarnitine + methylbutyrylcarnitine) and a median-chain acylcarnitine (octenoylcarnitine) decrease, while four long-chain acylcarnitines (tetradecanoylcarnitine, palmitoylcarnitine, palmitoleylcarnitine and oleoylcarnitine) increase with increasing birth weight. Age impacts the levels of all MS/MS NBS biomarkers, while sex only affects the level of malonylcarnitine + 3-hydroxybutyrylcarnitine (C3-DC + C4-OH) in very low birth weight preterm neonates. Conclusion: The current study developed reference intervals (RIs) specific to birth weight, age, and/or sex for 35 MS/MS biomarkers, which can help in the timely evaluation of the health and disease of preterm neonates.

- Abstract
The aim of this study was to investigate whether age at introduction of solid foods in preterm infants influences growth in the first year of life. This was a prospective observational study in very low birth weight infants stratified to an early (<17 weeks corrected age) or a late (≥17 weeks corrected age) feeding group according to the individual timing of weaning. In total, 115 infants were assigned to the early group, and 82 were assigned to the late group. Mean birth weight and gestational age were comparable between groups (early: 926 g, 26 + 6 weeks; late: 881 g, 26 + 5 weeks). Mean age at weaning was 13.2 weeks corrected age in the early group and 20.4 weeks corrected age in the late group. At 12 months corrected age, anthropometric parameters showed no significant differences between groups (early vs. late, mean length 75.0 vs. 74.1 cm, weight 9.2 vs. 8.9 kg, head circumference 45.5 vs. 45.0 cm). A machine learning model showed no effect of age at weaning on length and length z-scores at 12 months corrected age. Infants with comorbidities had significantly lower anthropometric z-scores compared to infants without comorbidities. Therefore, regardless of growth considerations, we recommend weaning preterm infants according to their neurological abilities. [ABSTRACT FROM AUTHOR]

This prospective study is to explore the role of specific circRNAs in predicting the development of bronchopulmonary dysplasia (BPD). Methods: From July 1, 2021 to December 1, 2021, peripheral blood samples were collected from 62 premature infants with gestational age (GA) ≤ 32 weeks on the 7th, 14th, and 28th day after birth. Then, on the 28th day, the included infants were divided into the BPD group and the non-BPD group according to the definition of BPD. Serum exosomal circRNAs from peripheral blood were identified, sequenced, and compared between the BPD and non-BPD groups at different time points. Specific differentially expressed circRNAs were further verified from another 42 enrolled premature infants (GA ≤ 32 weeks). The classical lung biological markers in serum were also measured simultaneously. Results: Hsa_circ_0001359 in serum exosomes showed continuous differential expression between the BPD group and the non-BPD group on the 7th, 14th, and 28th day. Compared with that, classical lung biological markers like IL-6, IL-33, KL-6, and ET-1 did not exhibit continuous differences. Moreover, the expression of hsa_circ_0001359 on day 7 had a higher predictive value in predicting BPD (area under curve:0.853, 95% CI:0.738– 0.968; adjusted odds ratio:6.033, 95% CI:2.373– 13.326). The calibration curve further showed the mean absolute error = 0.033, mean squared error = 0.00231, and quantile of absolute error = 0.058. Conclusion: Hsa_circ_0001359 in serum exosomes is a promising marker for predicting BPD in preterm infants with gestational age ≤ 32 weeks. [ABSTRACT FROM AUTHOR]

Home oxygen therapy (HOT) is frequently used as a therapeutic strategy for children experiencing chronic oxygen dependency associated with bronchopulmonary dysplasia (BPD). Recent studies have highlighted substantial variations in the characteristics and outcomes of infants requiring oxygen, primarily due to the absence of a consensus on the management of HOT in infants with BPD. We conducted this retrospective study and reviewed the medical records of extremely and very preterm infants who were diagnosed with BPD in a tertiary center in northern Taiwan from January 2020 to September 2021. Their neurodevelopmental outcomes were evaluated at 18 to 24 months of corrected age. A total of 134 patients diagnosed with BPD were divided into a HOT group (n = 39) and a room air group (n = 95). The children in the HOT group had a higher incidence of hemodynamic significant patent ductus arteriosus (PDA) (p = 0.005) and PDA ligation (p = 0.004), high-frequency oscillatory ventilation (p < 0.001), nitrogen oxide inhalation (p < 0.001), pulmonary hypertension (p = 0.01), and longer invasive ventilation (p < 0.001), as well as longer hospitalization (p < 0.001). A multivariate logistic regression model demonstrated that prolonged invasive ventilation (OR = 1.032, 95% CI 0.984–1.020, p = 0.001) was correlated with oxygen dependency in children. Infants with BPD born at advanced gestational age (OR = 0.760, 95%CI 0.582–0.992, p = 0.044) had a decreasing risk of requiring HOT. The children in the HOT group had a higher incidence of emergency room visits (p < 0.001) and re-hospitalization (p = 0.007) within one year of corrected age. The neurodevelopmental outcomes revealed the HOT group had an increasing portion of moderate to severe cognitive delay (18.2% vs. 3.7%, p = 0.009) and moderate to severe language delay (24.2% vs. 6.1%, p = 0.006) at 18 to 24 months of corrected age. In conclusion, infants with BPD necessitating HOT required prolonged invasive ventilation during hospitalization and exhibited a greater prevalence of unfavorable neurodevelopmental outcomes at 18 to 24 months of corrected age as well.

Antibiotic, analgesic sedative, and antiseizure medications are among the most commonly used medications in preterm/sick neonates, who are at high risk of nosocomial infections, central nervous system complications, and are exposed to numerous painful/stressful procedures. These severe and potentially life-threatening complications may have serious short- and long-term consequences and should be prevented and/or promptly treated. The reported variability in the medications used in neonates indicates the lack of adequate neonatal studies regarding their effectiveness and safety. Important obstacles contributing to inadequate studies in preterm/sick infants include difficulties in obtaining parental consent, physicians' unwillingness to recruit preterm infants, the off-label use of many medications in neonates, and other scientific and ethical concerns. This review is an update on the use of antimicrobials (antifungals), analgesics (sedatives), and antiseizure medications in neonates, focusing on current evidence or knowledge gaps regarding their pharmacokinetics, indications, safety, dosage, and evidence-based guidelines for their optimal use in neonates. We also address the effects of early antibiotic use on the intestinal microbiome and its association with long-term immune-related diseases, obesity, and neurodevelopment (ND). Recommendations for empirical treatment and the emergence of pathogen resistance to antimicrobials and antifungals are also presented. Finally, future perspectives on the prevention, modification, or reversal of antibiotic resistance are discussed. [ABSTRACT FROM AUTHOR]

- Abstract
To investigate noninvasive pressure-strain loop (PSL) combined with two-dimensional speck tracking imaging and left ventricular pressure measurement in the evaluation of cardiac function changes in anemia of prematurity (AOP) with different modes of respiratory support, and to explore its value in detecting subclinical myocardial injury in preterm infants. This retrospective study included 79 preterm infants with anemia, according to different modes of respiratory support, who were divided into invasive respiratory support group (39 cases) and noninvasive respiratory support group (40 cases). A control group of 40 nonanemic preterm infants with matched age, sex, and gestational age were also included. Complete echocardiography was performed for each included infant. There are PSL parameters that used to evaluate cardiac function, including global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE) among the three groups were compared. Compared with the control group, the value of GWI, GCW, and GWE were significantly lower and GWW was higher in the AOP groups (P < 0.05), and GWI, GCW and GWE were much significantly lower in the invasive respiratory support group than in the noninvasive respiratory support group (P < 0.05). There was no significant difference in GLS among the three groups (P > 0.05). Noninvasive PSL analysis can quantitatively assess myocardial work in AOP with different respiratory support, which is more sensitive than other conventional echocardiographic indices. This technique may provide a new method for monitoring subclinical myocardial injury with AOP. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. Method: Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. Results: There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. Conclusion: Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns.

Abstract Background To investigate the relationship between cord blood levels of Angiopoietin-1 (Ang-1) and S-endoglin (sCD105) and bronchopulmonary dysplasia (BPD) in preterm infants. Methods Sixty-one preterm infants admitted to the neonatal intensive care unit of the study hospital between July 2021 and September 2022 were included. Cord blood was collected after the birth of premature infants. Ang-1 and sCD105 levels were quantified using the vascular endothelial growth factor enzyme-linked immunosorbent assay. Preterm infants were divided into BPD and non-BPD groups, and differences in Ang-1 and sCD105 levels between the two groups were compared. A binary logistic model was used to assess the association between low and high levels Ang-1 and BPD in preterm infants. Results In the study, there were 20 preterm infants with BPD (32.8%) and 41 preterm infants with non-BPD (67.2%). Ang-1 concentration levels were lower in the BPD group than in the non-BPD group (7105.43 (5617.01–8523.00) pg/ml vs. 10488.03 (7946.19–15962.77) pg/ml, P = 0.027). However, the sCD105 concentration levels were not significantly different between the BPD and non-BPD groups (P = 0.246). A median Ang-1 concentration of 8800.40 pg/ml was calculated. Logistic regression analysis showed that after adjusting for gestational age, birth weight, and maternal prenatal steroid hormone application, the odds ratio (OR) was 8.577 for the risk of BPD in preterm infants with Ang-1 concentrations of ≤ 8800.40 pg/ml compared to those with Ang-1 concentrations of > 8800.40 pg/ml (OR: 8.577, 95% confidence interval: 1.265–58.155, P = 0.028). Conclusion Our study indicated that Ang-1 levels in the cord blood of preterm infants may be associated the risk of BPD. In the future, we will continue to conduct study with large samples.

Abstract Background Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown. This study compares the effectiveness of the INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E) technique with the less-invasive surfactant administration (LISA) technique, in increasing BPD-free survival of preterm infants. This is an international unblinded multicenter randomized controlled study in which preterm infants will be randomized into two groups to receive IN-REC-SUR-E or LISA surfactant administration. Methods In this study, 382 infants born at 24+0–27+6 weeks’ gestation, not intubated in the delivery room and failing nasal continuous positive airway pressure (nCPAP) or nasal intermittent positive pressure ventilation (NIPPV) during the first 24 h of life, will be randomized 1:1 to receive IN-REC-SUR-E or LISA surfactant administration. The primary outcome is a composite outcome of death or BPD at 36 weeks’ postmenstrual age. The secondary outcomes are BPD at 36 weeks’ postmenstrual age; death; pulse oximetry/fraction of inspired oxygen; severe intraventricular hemorrhage; pneumothorax; duration of respiratory support and oxygen therapy; pulmonary hemorrhage; patent ductus arteriosus undergoing treatment; percentage of infants receiving more doses of surfactant; periventricular leukomalacia, severe retinopathy of prematurity, necrotizing enterocolitis, sepsis; total in-hospital stay; systemic postnatal steroids; neurodevelopmental outcomes; and respiratory function testing at 24 months of age. Randomization will be centrally provided using both stratification and permuted blocks with random block sizes and block order. Stratification factors will include center and gestational age (24+0 to 25+6 weeks or 26+0 to 27+6 weeks). Analyses will be conducted in both intention-to-treat and per-protocol populations, utilizing a log-binomial regression model that corrects for stratification factors to estimate the adjusted relative risk (RR). Discussion This trial is designed to provide robust data on the best method of surfactant administration in spontaneously breathing preterm infants born at 24+0–27+6 weeks’ gestation affected by RDS and failing nCPAP or NIPPV during the first 24 h of life, comparing IN-REC-SUR-E to LISA technique, in increasing BPD-free survival at 36 weeks’ postmenstrual age of life.
