PURPOSE: To characterize changes in subfoveal choroidal thickness in preterm infants from 30 to 60 weeks postmenstrual age (PMA). DESIGN: The prospective, observational Study of Eye Imaging in Preterm infantS (BabySTEPS) enrolled infants eligible for retinopathy of prematurity screening per the American Association of Pediatrics guidelines. SUBJECTS: Infants imaged with an investigational, handheld OCT at ≥ 4 distinct imaging sessions between 30 to 60 weeks PMA as part of BabySTEPS. METHODS: Average choroidal thickness across the central subfoveal 1 mm in each eye at each time point was measured using custom segmentation software, and errors were manually corrected by a trained grader. We prospectively collected birth history data. A segmented mixed model was used to analyze the change in choroidal thickness as a function of PMA, birth weight, and gestational age (GA). MAIN OUTCOME MEASURES: Characterization of normative subfoveal choroidal thickness values and choroidal growth rate between 30 to 60 weeks PMA. RESULTS: We included 592 imaging sessions of 79 preterm infants (152 eyes). Mean (± standard deviation) GA was 27.5 ± 2.5 weeks. Mean choroidal thickness was 141.4 ± 34.5 μm at 30 weeks, 272.2 ± 83.9 μm at 38 weeks, and 306.2 ± 77.4 μm between 56 and 60 weeks. Between 30 and 60 weeks PMA, choroidal growth followed a biphasic model, with a linear growth rate of 14.8 μm per week (95% confidence interval [CI], 13.6-16.0) from 30 until 38.4 weeks, then cessation of growth, with a growth rate of 0.3 μm per week (95% CI, -1.1 to 1.6) from 38.4 to 60 weeks. Infants with extremely low birth weight (ELBW; < 1000 g) and extremely preterm (GA < 28 weeks) infants had significantly slower initial growth rates compared with very low and low birth weight and very preterm and preterm infants (ELBW 13.0 vs. 21.0 μm per week; P < 0.0001 and extremely preterm 13.2 vs. 18.0 μm per week; P = 0.003). CONCLUSIONS: Preterm infant choroidal thickness experiences rapid linear growth from 30 to 38 weeks PMA, at which time growth nearly stops. These foundational measurements and identification of the impact of extremes of low birth weight and prematurity on choroidal development will be essential as researchers begin to understand the role of choroidal development in ocular and retinal health in human infants.

Viability refers to an infant’s ability to survive outside the womb, which is influenced by both developmental maturity and the quality of medical care received. The concept of periviability, which has evolved alongside medical advancements, describes the stage between viability and nonviability, typically spanning from 200/7 to 25 6/7 weeks of gestation. While the chances of survival are extremely low at the earlier end of this range, the possibility of surviving without significant long-term complications improves towards the later end. The effectiveness of various antenatal and postnatal care practices, particularly those considered to be part of an active approach, plays a crucial role in influencing survival rates and mitigating morbidities. However, the decision to provide such active care is heavily influenced by national guidelines as well as international standards. The variability in guideline recommendations from one country to another, coupled with differences based on gestational age or accompanying risk factors, prevents the establishment of a standardized global approach. This variability results in differing practices depending on the country or institution where the birth occurs. Consequently, healthcare providers must navigate these discrepancies, which often leads to complex ethical dilemmas regarding the balance between potential survival and the associated risks. This review article explores the evolution of the definition of viability, the vulnerabilities faced by periviable infants, and the advancements in medical care that have improved survival rates. Additionally, it examines the viability and periviability definitions, the care and outcomes of periviable infants and recommendations in guidelines. [ABSTRACT FROM AUTHOR]

Background and aim: The anesthetic management of premature neonates has many challenges resulting from immature physiological adaptations, the transitional circulation, increased presence of comorbidities and, prominently, the occurrence of apnea in preterm infants. The aim of the present study was to compare the efficacy and safety of levobupivacaine with hyperbaric bupivacaine for spinal anesthesia in preterm infants scheduled for inguinal hernia repair. Methods: A double-blinded randomized, prospective, controlled study was conducted in a tertiary care pediatric surgery center from January 2017 to February 2021 where 60 preterm infants aged <45 weeks post-menstrual age (PMA) were scheduled for an elective inguinal hernia repair procedure. Preterm infants comforted by a sugared pacifier were divided randomly into two groups (30 infants each). Group I received spinal anesthesia with 1 mg/kg 0.5% hyperbaric bupivacaine, while group II received spinal anesthesia with1mg/kg o.5% levo-bupivacaine. The primary objective was to assess the hemodynamic stability, sensory and motor blockade of intrathecal levo-bupivacaine compared to hyperbaric bupivacaine in premature infants, and secondarily was to monitor the incidence of postoperative apnea, length of stay (LOS), and need for postoperative ventilator support. Results: The onset of sensory block of spinal anesthesia in group II was statistically significantly faster than in group I (Group I = 2.6 ± 0.52 min, Group II = 2.3 ± 0.35 min, p = 0.0112), with a statistically significant rapid regression in group II compared to group I (group I = 86 ± 2.45 min, Group II = 84 ± 3.67 min, p = 0.016). Conclusions: Levo-bupivacaine is an effective and safe agent for spinal anesthesia and has an equivalent potency to hyperbaric bupivacaine for motor blockade in premature infants requiring inguinal hernia repair surgery.

Introduction: Premature birth may impair a sensitive, responsive, enjoyable, and regulating parenting style, potentially leading to behavioral, cognitive, and emotional deficits in children. Additionally, the emotional bond between the parent and infant may be disturbed due to the restrictions and difficulties at the neonatal intensive care unit (NICU), further negatively impacting child development. Skin-to-skin contact (SSC) directly after birth is strongly recommended also for preterm or low birth weight infants since there is high-certainty evidence that SSC has positive effects on neonatal and maternal health as well as on the quality of the parent–child relationship. The aim of this study was to examine the effect of skin-to-skin contact immediately after childbirth on the development of emotional and behavioral problems in children born preterm entering school. Methods: This study is part of a randomized controlled delivery room skin-to-skin study (Deisy Study). A total of 33 children (aged 6–8 years) were assessed at school start. The German version of the CBCL/6-18R was used to evaluate the presence of behavior problems. Results: The perceived parental stress 6 months after discharge was the variable that most contributed to the variance explanation. SSC immediately after childbirth was not significant in the prediction of emotional and behavioral problems at school start. Limitations: The study was conducted in a small study group. Partners' variables were not included. Information regarding sociodemographic variables and bonding quality was collected 6 months (corrected age) after birth. The measurement of children's behavioral problems is not objective and corresponds to the parents' perception.

Aim Methods Results Conclusion To determine the association between the duration and types of antibiotic exposure and the occurrence of short‐ and long‐term outcomes among preterm, very‐low‐birthweight (VLBW) infants.Retrospective cohort study of VLBW infants born <32 weeks gestation between January 2017–December 2021. Association between antibiotic exposure and the occurrence of death and/or major morbidities, and neurodevelopmental impairment (NDI) at 18–24 months corrected age, was evaluated.A total of 728 infants were included—median gestation 28 weeks (IQR 26, 30) and median birthweight 1070g (IQR 850, 1300). Compared to no antibiotics, antibiotics exposure >3 days was significantly associated with increased risk of mortality and/or bronchopulmonary dysplasia (BPD)—adjusted odds ratio (AOR) 2.0 (95% CI 1.1–3.8; p=0.03), 3.5 (95% CI 1.6–7.8; p=0.01) and 3.8 (95% CI 1.6‐9.0; p<0.001) corresponding to antibiotic exposure of 4‐7 days, 8–14 and >14 days, respectively. Additional exposure to broad‐spectrum antibiotics was associated with AOR of 3.2 (95% CI 1.6–6.5; p<0.01) for death and/or BPD. There was no significant association between antibiotic exposure and NDI.Infants who received >3 days of antibiotics and/or additional broad‐spectrum antibiotics had significantly increased odds of death and/or BPD compared to no exposure. Antibiotic exposure was not significantly associated with NDI in our population. [ABSTRACT FROM AUTHOR]

Background: Nasal continuous positive airway pressure (NCPAP) is widely used for premature infants with respiratory distress syndrome (RDS). A high-flow nasal cannula (HFNC) provides positive end-expiratory pressure using high-flow oxygen; however, the variability in distending pressure is a primary concern. This study evaluated the feasibility and safety of a newly designed protocol for NCPAP weaning with cyclic HFNC use for premature infants. Methods: Premature infants with RDS using NCPAP support who were ready for weaning were enrolled. The weaning protocol used cyclic NCPAP with HFNC every 3 h for 3 days in the neonatal intensive care unit. The heart rate (HR), respiratory rate (RR), pulse oximetry (SpO2), transcutaneous carbon dioxide (PtcCO2), and cerebral tissue oxygen saturation (StO2) at the end of NCPAP with HFNC support were recorded once daily for 3 days. Results: From June 2019 to April 2021, 46 premature infants (27 male, 19 female) were enrolled. The mean gestational age and birth body weight were 28.7 ± 2.6 weeks and 1181 ± 354 g, respectively. No statistically significant differences in the HR, RR, SpO2, and cerebral StO2 during NCPAP weaning with HFNC were observed. However, the mean PtcCO2 with NCPAP was statistically significantly lower than that with HFNC (46.9 ± 6.0 mmHg vs. 47.9 ± 6.4 mmHg, P = 0.02). Conclusions: The feasibility and safety of the NCPAP weaning protocol with cyclic HFNC for premature infants are acceptable in this preliminary study. Due to the limited number of participants, further studies are required for more comprehensive analysis. Trial registration: This prospective observational case study was approved by the Human Experiment and Ethics Committee of our hospital (approval number: KMUHIRB-SV(I)-20180059; approval date: January 11, 2019).

Objectives: To assess whether continuous non-invasive pCO2 monitoring by transcutaneous pCO2 monitor (TCpCO2) among extremely low birth weight (ELBW) premature infants, during the first week of life, will decrease the rate of high-grade intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL) or the combined outcome of IVH/PVL and death. Methods: This was a prospective, observational, multicenter study. Due to ethical constraints, allocation was based on TCpCO2 monitor availability. ELBW infants were either monitored by TCpCO2 monitor (Sentec, Therwil, Switzerland) (study group), or recruited to the control group if a TCpCO2 monitor was not available. Results: A total of 132 ELBW infants participated in the study. The size of the study group (106 infants) and the control group (26 infants) differed because monitor availability increased during the study period reflecting change in standard of care. The groups had comparable gestational age and baseline characteristics. No difference was found in the rate of IVH/PVL in the study vs. control groups (10% vs. 4%; p = 0.7, respectively), or in the combined outcome of PVL/IVH and death (16% vs. 15%; p = 1.0, respectively). Conclusions: This study demonstrates the challenges in conducting a prospective controlled trial in a rapidly evolving medical field. While the study began with a clear equipoise, this balance shifted as the care team gained more experience with TCpCO2 monitoring among the study population, despite the absence of new clinical evidence to justify such a shift. Consequently, the small control group limited our ability to draw definitive conclusions regarding the study's objective. However, our findings may increase awareness of continuous non-invasive pCO2 monitoring in extremely premature infants. [ABSTRACT FROM AUTHOR]

Objective: Premature infants require special attention during nursing. This study aimed to explore the effects of baby touch on the growth, immunity, sleep and communication in premature infants. Methods: This was a retrospective study. A total of 64 premature infants with a gestational age of 30-36 weeks were selected at Maternity & Child Care Center of Qinhuangdao from June 2022 to May 2023, and randomly divided into experimental group and control group. The control group received routine comprehensive nursing care for newborns, while the experimental group was additionally treated with touch intervention using the international standard touch method. The effects of the three months touch on the growth and development, immunological function, sleep quality, and emotional communication of the premature infants were observed. Results: No statistically significant differences were found in gender, gestational age, birth weight, birth length, or head circumference at birth between the two groups (p> 0.05). In the third month, the increases in body weight, body length and head circumference were significantly more obvious, the immunological function indicators including CD3+, CD4+, CD8+, IgG, IgA and IgM were all significantly higher, the sleep time and sleep quality were both significantly superior, and the interaction time and intimacy with parents were significantly superior in the experimental group compared with the control group, with statistically significant differences (p< 0.05). Conclusion: Baby touch can promote growth and development, strengthen immunological function, improve sleep quality and enhance the emotional communication abilities of premature infants, and help them better adapt to the environment and grow.

• Parenting intervention boosts preterm development and parental mental health. • Parental emotional support enhances child development interventions. • Parent-led strategies improve practical access to interventions. • Efforts needed to assess key parenting factors for premature development. Parenting interventions have the potential to become effective strategies for improving the developmental trajectories of infants and children born prematurely. However, the effectiveness of parenting interventions is not well understood. A literature search was conducted in five databases. A total of 24 studies involving 3,636 participants were included for review. The results showed a significant effect in cognition, language, motor development, and behavioral problems of children born prematurely. Parenting stress, anxiety, and interactive behaviors showed significant effect size. This review focuses on interventions that employ scaffolding parenting strategies to enhance the development of children born prematurely. Efforts should continue to empower parents through effective and sustainable parenting interventions to improve the quality of life of preterm children. [ABSTRACT FROM AUTHOR]

Background: Premature newborns admitted to neonatal intensive care units (NICUs) undergo numerous painful interventions during care and treatment. The purpose of this study was to compare the effects of using sucrose and kangaroo mother care by on selected physiological variables and pain resulting from venipuncture in premature infants admitted to NICUs affiliated with Shiraz University of Medical Sciences. Methods: This clinical trial included premature infants admitted to 2 NICUs. The sample size consisted of 66 neonates, with 22 newborns in each group. Randomization was performed using the block allocation method. Data collection involved a demographic questionnaire, the neonatal infant pain scale, and a pulse oximetry device. Friedman, Kruskal–Wallis, and Dunn's post hoc tests employed for data analysis, with a significance level of P < 0.05. Results: The use of oral sucrose and kangaroo care demonstrated significant differences in breathing rate, heart rate, and average arterial blood oxygen saturation during and after venipuncture (P < 0.05). Oral sucrose was found to be significantly more effective than kangaroo care. Neonates under kangaroo care exhibited more regular heart rates compared to the other group (P < 0.05). The utilization of oral sucrose and kangaroo care had varying effects on the average pain score resulting from venipuncture in premature neonates (P < 0.05). Conclusions: Both methods proved effective in reducing pain and improving physiological variables. However, due to the superior effectiveness of sucrose administration, it is recommended as a cost-effective and easily implementable method in NICUs.

Soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOFlipid) is used without evidence of benefits. We investigated the relationship between lipid emulsions and brain injury in term-equivalent age magnetic resonance imaging (MRI) in 148 very preterm infants with a birth weight of < 1500 g at ≤ 32 gestational weeks in a neonatal intensive care unit. Infants who received soybean-based lipid emulsions between January 2015 and December 2018 were compared with those who received SMOFlipids between January 2019 and December 2022. A negative binomial generalized linear model was applied for bivariate analysis. Modified log-Poisson regression with generalized linear models and a robust variance estimator (Huber–White) were applied to adjust for potential confounders. The Kidokoro score was used to determine if lipid emulsion type would affect brain morphology and growth at term-equivalent age. Eighty-six (58.9%) received SMOFlipid. SMOFlipid was associated with lower focal signal abnormality, myelination delay, increased extracerebral space, and cerebellar volume reduction (P = 0.02, P = 0.007, P = 0.01, P = 0.02, respectively). SMOFlipidis are associated with brain insult, especially in white matter, cortical gray matter, and the cerebellum. Well-designed studies are needed to investigate the effect of lipid emulsions on the central nervous system. [ABSTRACT FROM AUTHOR]

Background Aims Study Design Results Conclusions Relevance to Clinical Practice Premature birth is a traumatic and stressful situation for parents who are immediately separated from their infant because of the newborn's need for specialized care. The staff of these units are in charge of following the principles of family‐centred care and practices for neonates at risk of neurodevelopmental disorders, including providing training to the family during their hospital stay and after being discharged.The aim of this study is to explore the perceptions of parents of premature children at risk of neurodevelopmental disorders in regard to care, interventions and assistance provided during the first months of their child's life.A qualitative descriptive study was carried out through individual interviews. The data analysis was conducted through a thematic analysis. The methodology and results were reported following the standards for preparing qualitative research reports and recommendations.Twenty‐one parents of premature children were interviewed. From these interviews, three main themes emerged: (i) parents' perspectives on preterm birth risk communication, (ii) navigating parental support and early interventions in preterm birth and (iii) perceptions of preterm birth protective and challenging factors.The parents of premature children need to receive better communication about the care and interventions for their child, and it is necessary that health personnel are better trained in terms of management and administration of public resources. Strategies must be implemented that continuously guide parents on the follow‐up and care of their premature child not only during their first moments of life but also after being discharged from the hospital.This study highlights the need to improve care for parents with premature infants at risk, emphasizing the necessity for health care system reforms and support structures, allowing health care professionals to enhance attention and care.

Background: Gastric tube insertion is necessary to support early enteral feeding of newborns during their neonatal intensive care stay. This frequent and invasive procedure is known to be painful. Very few analgesic techniques (sweet solutions, sucking, swaddling, and skin-to-skin contact) are available to reduce the pain caused by orogastric tube insertion procedure. Objective: To determine whether a new orogastric tube insertion technique modifies the pain response in newborns, we hypothesize that inserting an orogastric tube through the nipple of a bottle reduces pain caused by this procedure. Design: Prospective, controlled, randomized, multicentered and open label study. Setting(s): Three neonatal intensive care units in France (2 level 3 units and 1 level 2B). Participants: Full-term or premature newborns at 32 weeks of gestation or more, postnatal age between 48 hours and 21 days, not ventilated and requiring enteral feeding, were randomized into 2 groups: usual technique (n = 36) and experimental technique (n = 35). Methods: Our experimental technique was to insert the orogastric tube through a modified nipple of a bottle. This method was compared with the usual technique of inserting the tube directly into the newborn's mouth without a support to guide it accompanied by a nipple encouraging sucking with a nonnutritive solution. An association of nonnutritive sucking and orally administered 30% glucose was given to all children for analgesic purposes. Pain during the orogastric tube insertion was assessed on video recordings by 2 independent experts, using a heteroassessment behavioral scale for pain (DAN--Douleur Aiguë du Nouveau-né; APN--Acute Pain in Newborns). The primary outcome was an Acute Pain in Newborns score of less than 3 at the time of the procedure. Comparisons were made using Fisher exact test or Mann-Whitney U test. Factors associated with an Acute Pain in Newborns score of 3 and greater were explored using univariable and multivariable regression models. Results: All but 1 video recording in each group were analyzed. Among the 34 neonates in the experimental group, 71.4% (95% CI: [53.7-85.4]) had an Acute Pain in Newborns score of less than 3 during orogastric tube insertion versus 41% (95% CI: [27.9-61.9]) in the control group (P = .031). Gagging was frequent and nonsignificantly different between the 2 groups (69% in the control group, 51% in the experimental group, P = .13). In multivariable analysis, the experimental technique was an independent factor of pain prevention compared with the usual technique (odds ratio = 0.21 [0.06-0.71], P = .015). Conclusions: This study suggests that a simple, inexpensive, and feasible technique of orogastric tube insertion through the nipple of a bottle limits pain associated with this procedure in newborns.

Background: Premature infants have higher risks of infection due to their underdeveloped immune systems and changes to the oral cavity's normal flora colonization. Purpose: To assess the effect of oral colostrum application on the condition of the mouth and the incidence of late-onset sepsis (LOS) among premature infants. Methods: In this randomized controlled trial, 70 newborn premature infants were randomly allocated to colostrum or sterile water groups. The Mouth Care Assessment Tool was used to evaluate the condition of the mouth for 5 days after oral colostrum application. The incidence of LOS was measured using clinical and laboratory indicators from 72 hours after birth until discharge. Results: The condition of the mouth was significantly different on days 4 and 5, demonstrating that the colostrum group had less need for oral care (P < .001) compared to the control group. There was no significant difference between the 2 groups in clinical symptoms and laboratory values related to LOS (P > .05). Implications for practice: Oral colostrum application can benefit oral mucosal health and reduce the need for oral care among premature infants. It is also safe alternative oral care for premature infants who cannot breastfeed during the first few days of life. Future research should include infants of different gestational ages and mechanically ventilated infants to assess the effect of oral colostrum application on serum immune factors.

Abstract Background Nasal continuous positive airway pressure (NCPAP) is widely used for premature infants with respiratory distress syndrome (RDS). A high-flow nasal cannula (HFNC) provides positive end-expiratory pressure using high-flow oxygen; however, the variability in distending pressure is a primary concern. This study evaluated the feasibility and safety of a newly designed protocol for NCPAP weaning with cyclic HFNC use for premature infants. Methods Premature infants with RDS using NCPAP support who were ready for weaning were enrolled. The weaning protocol used cyclic NCPAP with HFNC every 3 h for 3 days in the neonatal intensive care unit. The heart rate (HR), respiratory rate (RR), pulse oximetry (SpO2), transcutaneous carbon dioxide (PtcCO2), and cerebral tissue oxygen saturation (StO2) at the end of NCPAP with HFNC support were recorded once daily for 3 days. Results From June 2019 to April 2021, 46 premature infants (27 male, 19 female) were enrolled. The mean gestational age and birth body weight were 28.7 ± 2.6 weeks and 1181 ± 354 g, respectively. No statistically significant differences in the HR, RR, SpO2, and cerebral StO2 during NCPAP weaning with HFNC were observed. However, the mean PtcCO2 with NCPAP was statistically significantly lower than that with HFNC (46.9 ± 6.0 mmHg vs. 47.9 ± 6.4 mmHg, P = 0.02). Conclusions The feasibility and safety of the NCPAP weaning protocol with cyclic HFNC for premature infants are acceptable in this preliminary study. Due to the limited number of participants, further studies are required for more comprehensive analysis. Trial registration This prospective observational case study was approved by the Human Experiment and Ethics Committee of our hospital (approval number: KMUHIRB-SV(I)-20180059; approval date: January 11, 2019).

Abstract Background Preterm infants often require non-invasive breathing support while their lungs and control of respiration are still developing. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is an emerging technology that allows infants to breathe spontaneously while receiving support breaths proportional to their effort. This study describes the first Australian Neonatal Intensive Care Unit (NICU) experience of NIV-NAVA. Methods Retrospective cohort study of infants admitted to a major tertiary NICU between October 2017 and April 2021 supported with NIV-NAVA. Infants were divided into three groups based on the indication to initiate NIV-NAVA (post-extubation; apnoea; escalation). Successful application of NIV-NAVA was based on the need for re-intubation within 48 h of application. Results There were 169 NIV-NAVA episodes in 122 infants (82 post-extubation; 21 apnoea; 66 escalation). The median (range) gestational age at birth was 25 + 5 weeks (23 + 1 to 43 + 3 weeks) and median (range) birthweight was 963 g (365–4320 g). At NIV-NAVA application, mean (SD) age was 17 days (18.2), and median (range) weight was 850 g (501–4310 g). Infants did not require intubation within 48 h in 145/169 (85.2%) episodes [72/82 (87.8%) extubation; 21/21 (100%) apnoea; 52/66 (78.8%) escalation). Conclusion NIV-NAVA was successfully integrated for the three main indications (escalation; post-extubation; apnoea). Prospective clinical trials are still required to establish its effectiveness versus other modes of non-invasive support.

With the increasing maturity of neonatal intensive care technology， the survival rate of premature infants has been increased significantly. At the same time， the incidence of brain injury has also been elevated year by year， and most of the affected children are complicated with early clinical manifestations and long-term sequelae of nervous system injury. Therefore， finding a simple and effective diagnostic method to improve the quality of life of premature infants has become a key problem to be solved urgently in the current field. In recent years， more and more biological markers of brain injury have been studied and applied to the early diagnosis and prognosis assessment of brain injury in premature infants. This article reviews the domestic and international research progress on these biological markers， aiming to provide reference for the early diagnosis and prognosis assessment of brain injury in premature infants.

Background: The environmental enrichment (EE) framework has inspired several early intervention (EI) approaches. This study evaluated the feasibility, safety, caregiver acceptance, and satisfaction of implementing the HEP Approach intervention, a novel EI model based on the EE paradigm. Outcome measures for motor development, individual functional goals, sensory functions, caregiver-provided environmental affordances, and motivation for movement were examined. Methods: A pre-post-study design examined 18 premature infants (<33 weeks six days gestation) with a corrected age of 4–10 months. A 21-item Likert scale survey assessed the feasibility, safety, acceptability, and satisfaction of implementing the HEP Approach intervention. The Peabody Developmental Motor Scales-2, Test of Sensory Functions in Infants, Affordances in the Home Environment for Motor Development, and Infant Movement Motivation Questionnaire were used for outcomes. The goal attainment scale measured progress toward parent goals. The HEP Approach consisted of 12 one-hour sessions implemented over three months. Results: Most participating parents found the HEP Approach intervention feasible, safe, acceptable, and satisfactory. GAS scores demonstrated significant gains with a mean t-score of 67.75 (SD = 2.00). Results found significant improvement (p ≤ 0.05) in all outcome measures. Conclusions: Results suggest that the HEP Approach intervention is safe, feasible, and acceptable to implement. Outcome measures were meaningful and sensitive in identifying improved motor development, individualized parental goals, sensory functions, caregivers' use of environmental opportunities, and movement motivation in premature at-risk infants. Results suggest further studies on the HEP Approach are feasible, and highlight the potential of this intervention to inspire and guide future research in this field. [ABSTRACT FROM AUTHOR]

Introduction: Despite the widely recognised benefits of breastfeeding, preterm newborns globally exhibit lower breastfeeding rates compared to term infants. This study aims to ascertain the prevalence of breast milk feeding among VLBW infants and to evaluate the factors associated with successful breast milk feeding in this specific population. Materials and methods: A cross-sectional study was conducted involving 111 mothers who gave birth to premature infants with birth weights less than 1500 g between March and December 2020. This investigation took place in two tertiary Neonatal Intensive Care Units. Data encompassing maternal, perinatal, and neonatal characteristics were extracted from medical records and subjected to analysis using SPSS version 25. Results: Among the 111 participating mothers, only 44 (39.6%) successfully provided expressed breast milk (EBM) for their infants' initial feeds, and a mere 31 (28.0%) sustained adequate EBM provision until their infants attained full enteral feeding. The achievement of a successful breast milk feeding establishment demonstrated substantial correlations with higher maternal income (p = 0.023) and the timing of initiating enteral feeds (p = 0.037). Conclusion: The prevalence of breast milk feeding initiation and establishment among VLBW infants was found to be remarkably low. The potential influence of the demanding Covid-19 pandemic context during the study period cannot be ignored. It is imperative to intensify efforts to investigate the underlying causes to facilitate the swift and effective implementation of quality improvement interventions. Future research initiatives are essential to uncovering additional confounding factors that might influence the successful rate of breast milk feeding among VLBW infants. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To determine the frequency and clinical features of the late preterm infants with feeding intolerance. MATERIASL AND METHODS: Medical records of 426 infants with gestational age of 340/7- 366/7 weeks were retrospectively reviewed for the study. Clinical and demographic features of late preterm infants and episodes of feeding intolerance were recorded. RESULTS: A total of 54 late preterm infants with feeding intolerance were evaluated and compared with 178 infants without feeding intolerance. Baseline demographics were similar between groups. Mean duration of intolerance period was 2.3 ± 1.2 days. Time to full enteral feeding was significantly longer in late preterm infants with feeding intolerance when compared with infants without feeding intolerance (8 ± 2.3 vs 5.2 ± 1.7 days, respectively, p<0.001). Breastfeeding rates were similar between the groups. Rate of prokinetic use in the feeding intolerance group was 37%. There were no differences between the time to full enteral feeding and the duration of parenteral nutrition between prokinetic users and non-users. CONCLUSIONS: Although the gestational ages of late preterm infants are close to term and their size is relatively large, they are not like term infants. These infants should be followed closely in terms of feeding problems as well as many morbidities. [ABSTRACT FROM AUTHOR]

BACKGROUND: The high morbidity of necrotizing enterocolitis (NEC) in very low birth weight infants (<1500 grams) (VLBW) requires the search for prevention strategies that are more effective than treatment. Current evidence supports the use of probiotics as protective factors. OBJECTIVES: To determine if probiotic supplementation in VLBW infants represents a preventive factor for the development of NEC. METHODS: Retrospective cohort study conducted in 145 VLBW infants, where the presence of NEC was evaluated in populations supplemented with L. reuteri, B. lactis or not supplemented. The comparison among groups was performed with the chi-square test for maximum likelihood-ratio. RESULTS: Of 66 supplemented patients, 86.4% did not present NEC (RR 0.23 [95% Ci: 0.12-0.43]; p<0.0001). In those not supplemented, the incidence of NEC was 59.5%. An NNT of 1.7 to 3.1 was obtained. CONCLUSIONS: Despite the heterogeneity in clinical studies of probiotic supplementation, the evidence is strongly in favor of probiotic treatment for the prevention of NEC. This study found that supplementation from the first days of life at doses of 600 million CFUs/ day was more effective in preventing the presentation of NEC than higher doses. [ABSTRACT FROM AUTHOR]

Mechanisms resulting from the physiological immaturity of the digestive system in children delivered before 32 weeks of gestation and, in particular, different interactions between the microbiome and the body have not been fully elucidated yet. Next-generation sequencing methods demonstrated the presence of bacterial DNA in the placenta and amniotic fluid, which may reflect bacterial populations that initiate intestinal colonization in utero. Numerous studies confirmed the hypothesis stating that intestinal bacteria played an important role in the pathogenesis of necrotizing enterocolitis (NEC) early- and late-onset neonatal sepsis (EONS and LONS). The model and scale of disorders within the intestinal microbiome are the subject of active research in premature infants. Neonatal meconium was primarily used as an indicator defining the environment in utero, as it is formed before birth. Metagenomic results and previous data from microbiological bacterial cultures showed a correlation between the time from birth to sample collection and the detection of bacteria in the neonatal meconium. Therefore, it may be determined that the colonization of the newborn's intestines is influenced by numerous factors, which may be divided into prenatal, perinatal, and postnatal, with particular emphasis put on the mode of delivery and contact with the parent immediately after birth. Background: The aim of this review was to collect available data on the intrauterine shaping of the fetal microbiota. Methods: On 13 March 2024, the available literature in the PubMed National Library of Medicine search engine was reviewed using the following selected keywords: "placental microbiome", "intestinal bacteria in newborns and premature infants", and "intrauterine microbiota". Results: After reviewing the available articles and abstracts and an in-depth analysis of their content, over 100 articles were selected for detailed elaboration. We focused on the origin of microorganisms shaping the microbiota of newborns. We also described the types of bacteria that made up the intrauterine microbiota and the intestinal microbiota of newborns. Conclusions: The data presented in the review on the microbiome of both term newborns and those with a body weight below 1200 g indicate a possible intrauterine colonization of the fetus depending on the duration of pregnancy. The colonization occurs both via the vaginal and intestinal route (hematogenous route). However, there are differences in the demonstrated representatives of various types of bacteria, phyla Firmicutes and Actinobacteria in particular, taking account of the distribution in their abundance in the individual groups of pregnancy duration. Simultaneously, the distribution of the phyla Actinobacteria and Proteobacteria is consistent. Considering the duration of pregnancy, it may also be concluded that the bacterial flora of vaginal origin dominates in preterm newborns, while the flora of intestinal origin dominates in term newborns. This might explain the role of bacterial and infectious factors in inducing premature birth with the rupture of fetal membranes. [ABSTRACT FROM AUTHOR]

This study aimed to explore the real experiences and needs of neonatal intensive care unit (NICU) preterm intergenerational caregivers for discharge preparation and provide a basis for nursing staff to formulate systemic and personalized health education plans and continuous nursing plans for preterm discharge. This was a descriptive qualitative study. An objective sampling method was used to select 16 intergenerational caregivers of preterm infants admitted to the NICU of tertiary obstetrics and gynecology hospitals in Zhejiang and Jilin provinces from December 2023 to February 2024. Semi-structured interviews were conducted on the day of discharge of the preterm infants and six weeks after discharge. Colaizzi's seven-step analysis method was used to analyze the interview data. Based on the existence, relatedness, and growth (ERG) theory, the discharge preparation experiences and needs of neonatal intergenerational caregivers in the NICU were summarized into three themes: psychological condition, care capacity condition, and multi-party support needs. In the process of hospital discharge preparation, intergenerational caregivers of premature infants in NICU have multiple needs, including enhancing nursing ability and obtaining psychological and multi-party support. It is helpful to take effective interventions to improve their readiness for discharge. The nursing staff should develop personalized discharge health education plans and continuous nursing plans to improve the level of discharge preparation. There were no patient or public contributions. • Intergenerational caregivers are one of the main caregivers after discharge of premature infants in China, but their level of discharge readiness is easily overlooked. • In the process of discharge preparation, the intergenerational caregivers of premature infants in NICU have various needs such as enhancing independent care ability, obtaining professional guidance from medical staff and family emotional support. • Medical institutions should develop personalized discharge health education plan and continuous care plan for intergenerational caregivers to improve their discharge readiness.

Polyunsaturated fatty acids (PUFAs), especially arachidonic acid (ARA) and docosahexaenoic acid (DHA), are extremely important fatty acids for brain development in the fetus and early childhood. Premature infants face challenges obtaining these two fatty acids from their mothers. It has been reported that supplementation with triacylglycerols (TAGs) with an ARA:DHA (w/w) ratio of 2:1 may be optimal for preterm infants, as presented in commercial formulas such as Formulaid™. This study explored methods to produce TAGs with a 2:1 ratio (ARA:DHA), particularly at the more bioavailable sn-2 position of the glycerol backbone. Blending and enzymatic acidolysis of microalgae oil (rich in DHA) and ARA-rich oil yielded products with the desired ARA:DHA ratio, enhancing sn-2 composition compared to Formulaid™ (1.6 for blending and 2.3 for acidolysis versus 0.9 in Formulaid™). Optimal acidolysis conditions were 45 °C, a 1:3 substrate molar ratio, 10% Candida antarctica lipase, and 4 h. The process was reproducible, and scalable, and the lipase could be reused. In vitro digestion showed that 75.5% of the final product mixture was bio-accessible, comprising 19.1% monoacylglycerols, ~50% free fatty acids, 14.6% TAGs, and 10.1% diacylglycerols, indicating better bio-accessibility than precursor oils.

Background: Being an unexpected, undesired and life-threatening situation, preterm birth (PTB) is a stress-, anxiety- and depression-generating factor for women delivering prematurely. The aim of this study was to assess the relationship between self-efficacy, coping strategies and perceived stress in mothers who experienced preterm birth and full-term birth, to determine the needs for personalized emotional support. Methods: The study was conducted among 251 women divided into the preterm birth group (PBG) and the full-term birth group (FBG). Data were collected using the following: (1) The State-Trait Anxiety Inventory (STAI) Questionnaire, (2) Generalized Self-Efficacy Scale (GSES) and (3) Coping Inventory for Stressful Situations Questionnaire (CISS), which were distributed online from January 2021 to June 2021. Results: Lower STAI scores were recorded in the preterm birth group (PBG) with high self-efficacy (HSE) when compared to the full-term birth group with HSE. CISS test scores were higher in PBG women with low self-efficacy (LSE) in comparison to women with LSE in FBG (p < 0.001). A positive and strong relationship (0.83; p < 0.05) was found between avoidance-oriented style and strategy of avoidance by engaging in surrogate activities and a positive moderate relationship (0.58; p < 0.05) with the style of looking for social contacts in PBG with LSE. Conclusions: The task-oriented coping style seems to be the most beneficial strategy for mothers, regardless of their preterm or term delivery, as focusing on specific activities increases the sense of self-efficacy and the anxiety level can decrease. Awareness of different styles of coping with stress and a sense of self-efficacy are necessary to plan personalized interventions for premature infants' mothers. [ABSTRACT FROM AUTHOR]

Background: Preterm infants often require non-invasive breathing support while their lungs and control of respiration are still developing. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is an emerging technology that allows infants to breathe spontaneously while receiving support breaths proportional to their effort. This study describes the first Australian Neonatal Intensive Care Unit (NICU) experience of NIV-NAVA. Methods: Retrospective cohort study of infants admitted to a major tertiary NICU between October 2017 and April 2021 supported with NIV-NAVA. Infants were divided into three groups based on the indication to initiate NIV-NAVA (post-extubation; apnoea; escalation). Successful application of NIV-NAVA was based on the need for re-intubation within 48 h of application. Results: There were 169 NIV-NAVA episodes in 122 infants (82 post-extubation; 21 apnoea; 66 escalation). The median (range) gestational age at birth was 25 + 5 weeks (23 + 1 to 43 + 3 weeks) and median (range) birthweight was 963 g (365–4320 g). At NIV-NAVA application, mean (SD) age was 17 days (18.2), and median (range) weight was 850 g (501–4310 g). Infants did not require intubation within 48 h in 145/169 (85.2%) episodes [72/82 (87.8%) extubation; 21/21 (100%) apnoea; 52/66 (78.8%) escalation). Conclusion: NIV-NAVA was successfully integrated for the three main indications (escalation; post-extubation; apnoea). Prospective clinical trials are still required to establish its effectiveness versus other modes of non-invasive support. [ABSTRACT FROM AUTHOR]

Periodic breathing (PB)-related intermittent hypoxia can have long-lasting deleterious consequences in preterm infants. Olfactory stimulation using vanilla odor is beneficial for apnea of prematurity in the first postnatal days/weeks. We aimed to determine for the first time whether vanilla odor can also decrease PB-related intermittent hypoxia. This pilot study was a balanced crossover clinical trial including 27 premature infants born between 30 and 33+6 weeks of gestation. We performed 12-h recordings on two nights separated by a 24-h period. All infants were randomly exposed to vanilla odor on the first or second study night. The primary outcome was the desaturation index, defined as the number per hour of pulse oximetry (SpO 2) values <90 % for at least 5 s, together with a drop of ≥5 % from the preceding value. Univariate mixed linear models were used for the statistical analysis. Overall, exposure to vanilla odor did not significantly decrease the desaturation index (52 ± 22 events/h [mean ± SD] on the intervention night vs. 57 ± 26, p = 0.2); furthermore, it did not significantly alter any secondary outcome. In a preliminary post hoc subgroup analysis, however, the effect of vanilla odor was statistically significant in infants with a desaturation index of ≥70/h (from 86 ± 12 to 65 ± 23, p = 0.04). In this pilot study, vanilla odor overall did not decrease PB-related intermittent hypoxia in infants born at 30–33+6 weeks of gestation, which is when they are close to term. Preliminary results suggesting a beneficial effect in infants with the highest desaturation index, however, justify further studies in the presence of PB-related intermittent hypoxia as well as in infants born more prematurely.

Background: The thalamus L-sign, characterized by damage to the lateral and posterior parts of the thalamus, has recently been identified as a potential marker of partial prolonged hypoxic-ischemic injury (HII). Although prematurity-related thalamic injury is well documented, its association with the thalamus L-sign is infrequently described. Objective: The primary objective of this study was to further investigate the thalamus L-sign in premature birth and white matter injury. Materials and methods: A retrospective analysis of 246 brain magnetic resonance imaging (MRI) scans from preterm infants born before 37 weeks of gestation was conducted to explore the occurrence, characteristics, and associations of the thalamus L-sign with white matter injury. Results: The L-sign was detected in 12.6% of patients with periventricular leukomalacia (PVL), primarily in severe cases (57.9% of severe PVL). All cases were associated with posterior parieto-occipital PVL. Four patients exhibited unilateral or asymmetric L-signs, which were linked to high-grade intraventricular hemorrhage (IVH) or periventricular hemorrhagic infarction on the ipsilateral side, with the most severe white matter injury occurring on that side. No significant differences were observed regarding gestational age at birth, duration of neonatal intensive care unit hospitalization, percentage of IVH, hypoglycemia, or jaundice between patients with moderate-to-severe PVL with and without the thalamus L-sign. Conclusion: The thalamus L-sign may serve as a marker for severe parieto-occipital PVL and may be exacerbated and appear asymmetric in cases of ipsilateral IVH or periventricular hemorrhagic infarction.

Objective Nasal high-frequency oscillatory ventilation (nHFOV) and synchronized nasal intermittent positive pressure ventilation (sNIPPV) were the new modes of noninvasive ventilation. This study's aim was to clarify as to which of the nHFOV and sNIPPV modes was superior in preventing postextubation failure or reintubation in neonates. Study Design An open-label parallel randomized study was performed. Extubated preterm and term neonates were randomly allocated into nHFOV or sNIPPV modes; the reintubation rate was evaluated within 7 days after extubation between the two modes. Subgroup analyses were performed for preterm (gestational age <37 weeks) and very preterm (gestational age <32 weeks) neonates. The sample calculation was 1,050 neonates; however, this trial was stopped early as enrollment was too slow. Results From July 2020 to June 2022, 202 neonates were assessed for eligibility and 69 neonates were excluded. Finally, 133 neonates were randomly allocated to the study interventions (nHFOV = 67, sNIPPV = 66). The median gestational age and birth weight were 33 (30–37) weeks and 1,910 (1,355–2,836) g, respectively. The reintubation rate within 7 days did not significantly differ between the groups (nHFOV [5/67, 7%] vs. sNIPPV [4/66, 6%]); risk difference [95% confidence interval] = 0.01 [−0.08 to 0.11]; p = 0.99), including preterm (nHFOV [4/55, 7%] vs. sNIPPV [3/44, 7%]) and very preterm (nHFOV [3/25, 12%] vs. sNIPPV [3/25, 12%]) neonates. Conclusion After neonatal extubation, there was no significant difference of reintubation rates within 7 days between nHFOV and sNIPPV. This trial has been registered in the ClinicalTrials.gov database (https://clinicaltrials.gov/ct2/show/NCT04323397). First posted registration on March 26, 2020. Key Points There was no significant difference of reintubation rates between nHFOV and sNIPPV. During nHFOV support, one neonate developed pneumomediastinum. During sNIPPV support, one neonate developed pulmonary hemorrhage. [ABSTRACT FROM AUTHOR]

Background: Preterm infants require the use of nasogastric and orogastric enteral access devices (EADs) to provide nutrition and medications. Confirmation of the location of the tip of the EAD is essential to minimize complications. At the study site, EAD location was limited to verifying the centimeter marking at the lip/nares and nonevidence-based methods of visual observation of aspirate and auscultation. Purpose: Implement an evidenced-based EAD placement confirmation protocol, and by 90 days post-education and implementation, achieve adherence of 90%. Methods: This quality improvement project implemented a nurse-driven evidence-based protocol for EAD verification. The intervention was based on the New Opportunities for Verification of Enteral Tube Location best practice recommendations. Prior to implementation, education sessions focused on insertion measurement technique and gastric pH measurement. Radiographs, insertion measurement technique, centimeter marking, and gastric pH measurement were used for EAD location confirmation. To determine compliance with the protocol, audits were conducted and questionnaires assessing current practice regarding EAD confirmation were administered pre- and postimplementation. Results: The protocol increased nursing knowledge regarding evidence-based EAD insertion and verification procedures, incorporated pH measurement into practice, and reduced use of auscultation for confirmation. Nursing adherence to the protocol was 92%. Implications for Practice and Research: This provides a model for how to successfully implement and achieve adherence to an evidence-based EAD placement confirmation nurse-driven protocol. Further research is needed to verify the effectiveness of the protocol and establish consensus on approaches specifically for the neonatal population. [ABSTRACT FROM AUTHOR]

Rationale: Hemodynamically significant patent ductus arteriosus (hsPDA) in premature infants has been associated with bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH). However, these associations remain incompletely understood. Objectives: To assess the associations between hsPDA duration and clinical outcomes, PH, and phenotypic differences on lung magnetic resonance imaging (MRI). Methods: In this retrospective cohort study, we identified all infants with BPD at <32 weeks' gestation who also underwent research lung MRI at <48 weeks' postmenstrual age (PMA) from 2014 to 2022. Clinical echocardiograms were reviewed for hsPDA and categorized as no hsPDA, hsPDA 1–60 days, and hsPDA >60 days. Outcome variables included BPD severity, PH at 36 weeks' PMA, PH after 36 weeks' PMA in the absence of shunt (PH–pulmonary vascular disease [PVD]), tracheostomy or death, and lung phenotype by MRI via modified Ochiai score, indexed total lung volume, and whole-lung hyperdensity. Logistic regression and ANOVA were used. Measurements and Main Results: In total, 133 infants born at 26.2 ± 1.9 weeks, weighing 776 ± 276 g, were reviewed (47 with no hsPDA, 44 with hsPDA 1–60 days, and 42 with hsPDA >60 d). hsPDA duration > 60 days was associated with BPD severity (P < 0.01), PH at 36 weeks' PMA (adjusted odds ratio [aOR], 9.7 [95% confidence interval (CI), 3.3–28.4]), PH–PVD (aOR, 6.5 [95% CI, 2.3–18.3]), and tracheostomy or death (aOR, 3.0 [95% CI, 1.0–8.8]). Duration of hsPDA > 60 days was associated with higher Ochiai score (P = 0.03) and indexed total lung volume (P = 0.01) but not whole-lung hyperdensity (P = 0.91). Conclusions: In infants with moderate or severe BPD, prolonged exposure to hsPDA is associated with BPD severity, PH–PVD, and increased parenchymal lung disease by MRI. [ABSTRACT FROM AUTHOR]

Background: The aim of this study is to investigate the diagnostic value of cerebrospinal fluid (CSF) and serum levels of the soluble form of triggering receptor-1 expressed on myeloid cells (sTREM-1) in neonatal meningitis. Methods: Serum sTREM-1 levels were measured in all neonatal sepsis patients at the start of antibiotic therapy and the 48th hour of treatment. At the beginning of antibiotic therapy, CSF samples were collected for sTREM-1 measurements. Control CSF samples were also collected from the patients with meningitis at the 48th hour of treatment. Results: A total of 77 preterm (50) and term (27) patients with neonatal sepsis were included in the study. There was no significant difference between the CSF sTREM-1 levels of patients with and without meningitis. The CSF sTREM-1 levels of preterm infants with meningitis decreased significantly after treatment (p = 0.038). Although the CSF/serum sTREM-1 ratios tended to increase in babies with meningitis, no significant difference was found between the groups. CSF/serum sTREM-1 ratios (mean ± SD) were 1.42 ± 0.91 and 1.14 ± 0.85 in preterm babies with and without meningitis and 1.15 ± 0.97 and 0.97 ± 0.55 in term babies with and without meningitis, respectively. Conclusions: Serum and CSF sTREM-1 levels increase in patients with neonatal sepsis. CSF s-TREM-1 levels decrease after treatment in preterm infants with meningitis. [ABSTRACT FROM AUTHOR]

Background. In clinical practice, it is crucial to identify diagnostic methods that can forecast the neurodevelopmental outcomes of very preterm neonates. Our study aimed to assess the predictive significance of amplitude-integrated electroencephalography (aEEG) for the neurodevelopmental outcomes of preterm infants at 12 months corrected age and to establish the cut-off score that could indicate potential neurodevelopmental impairments. Methods. Preterm neonates born before 32 weeks of gestational age between June 2020 and July 2022 were included in a prospective manner. Amplitude-integrated electroencephalography recordings were conducted at five age intervals (days 1–3; first, second, third and fourth weeks). Recordings were analyzed using the Burdjalov scoring system. The neurodevelopment assessment with Bayley Scales of Infant Development—Second Edition was carried out at 12 months corrected age. Results. A total of 140 newborns were included in the study. Neurodevelopment was assessed in 108 infants at 12 months corrected age. Higher total aEEG Burdjalov scores were observed in groups with normal cognitive and motor development. The most sensitive and specific score for prediction of cognitive impairment in 12 months corrected age was an aEEG evaluation of 5.5 according to Burdjalov score within the first three days. The most sensitive and specific score for prediction of motor impairment was 8.5 within the first week. Conclusions. According to our research there is currently not enough data to accurately foresee the development of newborns at 12 months corrected age according to early aEEG test results. However, conducting a research with bigger sample size and repeated evaluations at a later age might increase the prognostic value of aEEG. In this study cut-off scores of aEEG performed early in life to predict later neurodevelopment outcomes were determined. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusion To describe the effect of resuscitation with bubble CPAP (bCPAP) versus T‐piece device at birth on early clinical parameters and hospital outcomes in infants born <32 weeks gestation.This is a single‐centre pre‐ and post‐implementation study comparing outcomes in two epochs. In epoch 1 (1 July 2013–31 December 2014), infants were managed with non‐humidified gas using Neopuff® T‐piece devices to support breathing after birth. In epoch 2 (1 March 2020–31 December 2021), routine application of bCPAP with humidified gas was introduced at birth.Three hundred fifty‐seven patients were included (176 epoch 1, 181 epoch 2). The mean gestational age was 28 ± 2 weeks. The demographics of the two epochs were comparable. There were significant improvements in outcomes of infants in epoch 2 with less infants intubated at delivery (16% vs. 4%, P ≤ 0.001), improved 5 min Apgar (7 vs. 8, P ≤ 0.001), reduced need for ventilation (21% vs. 8.8%, P ≤ 0.001), duration of ventilation in the first 72 h (9.6 vs. 4.6 h) and mortality (10.8% vs. 1.7%, P ≤ 0.001). There was, increased incidence of chronic lung disease (30% vs. 55%, P = 0.02) but no increase in infants discharged on oxygen (3.8% vs. 5%, P = 0.25). Similar findings were observed in a subgroup of infants born <25 weeks' gestation with no increase in the incidence of CLD.Introducing application of bCPAP from the first breaths in infants <32 weeks' gestation was associated with better short‐term outcomes and mortality, albeit with increased incidence of CLD. The subgroup of infants born <25 weeks' gestation showed similar change in outcomes, with no increase in CLD. [ABSTRACT FROM AUTHOR]

With the increasing maturity of neonatal intensive care technology, the survival rate of premature infants has been increased significantly. At the same time, the incidence of brain injury has also been elevated year by year, and most of the affected children are complicated with early clinical manifestations and long-term sequelae of nervous system injury. Therefore，finding a simple and effective diagnostic method to improve the quality of life of premature infants has become a key problem to be solved urgently in the current field. In recent years, more and more biological markers of brain injury have been studied and applied to the early diagnosis and prognosis assessment of brain injury in premature infants. This article reviews the domestic and international research progress on these biological markers, aiming to provide reference for the early diagnosis and prognosis assessment of brain injury in premature infants.

Introduction: This overview aims to systematically review evidence regarding effects of interventions undertaken in neonatal units to increase breastfeeding in preterm infants. Methods: We followed Cochrane methodology. Systematic reviews published to October 31, 2022, reporting meta-analysis of effects from original studies on breastfeeding rates in preterm infants of neonatal unit interventions designed to increase breastfeeding were included. Results: Avoidance of bottles during breastfeed establishment (comparator breastfeeds with bottle-feeds) demonstrated clear evidence of benefit for any breastfeeding at discharge and exclusive breastfeeding 3 months post-discharge, and possible evidence of benefit for exclusive breastfeeding at discharge, and any breastfeeding post-discharge. Kangaroo mother care (KMC) (comparator usual care) demonstrated clear evidence of benefit for any and exclusive breastfeeding at discharge and possible benefit for any breastfeeding post-discharge. Quality improvement (QI) bundle(s) to enable breastfeeds (comparator conventional care) showed possible evidence of benefit for any breastfeeding at discharge. Cup feeding (comparator other supplemental enteral feeding forms) demonstrated possible evidence of benefit for exclusive breastfeeding at discharge and any breastfeeding 3 months after. Early onset KMC (commenced <24 h post-birth), oral stimulation, and oropharyngeal colostrum administration, showed no evidence of benefit. No meta-analyses reported pooled effects for gestational age or birthweight subgroups. Conclusion: There is ample evidence to support investment in KMC, avoidance of bottles during breastfeed establishment, cup feeding, and QI bundles targeted at better supporting breastfeeding in neonatal units to increase prevalence of breastfeeding in preterm infants and promote equal access to breastmilk. Stratifying effects by relevant subgroups is a research priority. [ABSTRACT FROM AUTHOR]

The trial aimed to assess the impact on pain scores of the administration of oral glucose solutions at different concentrations and in combination with supportive positions during heel puncture procedures. This trial was structured as a quadruple-blinded experimental study conducted at a single center – a Level II and IVa NICU between June 2022–2023. Included in the study were 128 premature infants born with a gestational age of between 33 and 36 weeks and a postnatal age of <7 days. For the heel puncture procedures, four distinct interventions were employed, each involving supportive positions and oral solutions. All interventions were recorded on video for analysis, and data were collected using the "Infant Information and Observation Form" and "Neonatal Pain, Agitation and Sedation Scale (N-PASS)". The N-PASS was rated by two independent nurses. The data were analyzed with the two-way repeated measures ANOVA and post-hoc Bonferroni tests. The descriptive and clinical characteristics were similar in all groups (p > 0.05). The pain scores, physiological variables and total crying times of the premature infants differed significantly depending on the interventional groups and times, and the interaction between the groups and times (p < 0.05). Combining glucose solutions with supportive positions led to a reduction in pain scores, a decrease in total crying time when compared to the use of supportive positions alone. Combining an oral 20% glucose solution with supportive positions can be recommended to reduce pain during unplanned heel puncture procedures in the absence of a parent in the unit. • From the very first days of life, all infants experience procedural pain. • Effective pain management are integral to developmental care. • Ineffective management of pain has short- and long-term adverse consequences. • Combining oral glucose solutions with supportive positions can be effective in reducing pain responses. • Combining oral glucose solutions with supportive positions contributes to effective pain regulation.

ABSTRACTObjective: Preterm babies are prone to experiencing apnea of prematurity (AOP), mostly characterised by a pause in breathing lasting a minimum of 20 seconds. Recent literature supported higher maintenance doses of caffeine, indicating benefits. This study evaluated the cost-effectiveness of high maintenance dose (HD) versus low maintenance dose (LD) caffeine for AOP in neonates.Methods: From the hospital perspective of Hamad Medical Corporation (HMC), Qatar, a cost-effectiveness decision-analytic model was constructed to follow the use of a HD maintenance caffeine of 20 mg/kg/dose versus a LD maintenance caffeine of 10 mg/kg/dose, in a simulated cohort of AOP neonates, over a therapy follow-up duration of six weeks, until neonatal intensive care (NICU) discharge. The clinical inputs were primarily literature-based, while the resource cost and utilisation were locally extracted in HMC. The cost-effectiveness outcome measure was calculated per therapy success, defined as survival with no apnea and successful extubation removal within 72 hours, with or without adverse events. One-way and multivariate sensitivity analyses were performed to confirm the robustness of the results.Results: With 0.23 (95% CI, 0.23–0.23) enhancement in success rate, at United States dollar (US$) 3869 (95% CI, US$ 3823–3915) added infant cost, the HD caffeine was between dominant (34.8%) and cost-effective (63.7%), with an average incremental cost-effectiveness ratio of US $16,895 (95% CI, US$ 15,242–18,549) relative to LD caffeine per additional case of success. The hospitalisation contributed the most to the total infant cost, and the probability of patent ductus arteriosus was the model input that influenced the results most.Conclusion: This is the first literature economic evaluation of caffeine for AOP. Despite increasing the cost of therapy, HD maintenance caffeine seems to be a cost-effective alternative to LD caffeine in Qatar. Our results support the recent global trends of increased use of HD caffeine for AOP in NICU.

IntroductionPremature birth may impair a sensitive, responsive, enjoyable, and regulating parenting style, potentially leading to behavioral, cognitive, and emotional deficits in children. Additionally, the emotional bond between the parent and infant may be disturbed due to the restrictions and difficulties at the neonatal intensive care unit (NICU), further negatively impacting child development. Skin-to-skin contact (SSC) directly after birth is strongly recommended also for preterm or low birth weight infants since there is high-certainty evidence that SSC has positive effects on neonatal and maternal health as well as on the quality of the parent–child relationship. The aim of this study was to examine the effect of skin-to-skin contact immediately after childbirth on the development of emotional and behavioral problems in children born preterm entering school.MethodsThis study is part of a randomized controlled delivery room skin-to-skin study (Deisy Study). A total of 33 children (aged 6–8 years) were assessed at school start. The German version of the CBCL/6-18R was used to evaluate the presence of behavior problems.ResultsThe perceived parental stress 6 months after discharge was the variable that most contributed to the variance explanation. SSC immediately after childbirth was not significant in the prediction of emotional and behavioral problems at school start.LimitationsThe study was conducted in a small study group. Partners' variables were not included. Information regarding sociodemographic variables and bonding quality was collected 6 months (corrected age) after birth. The measurement of children's behavioral problems is not objective and corresponds to the parents' perception.Clinical Trial Registrationhttps://clinicaltrials.gov, deisy study NCT01959737, deisy follow up NCT03366285.

AimTo provide a risk prediction for bronchopulmonary dysplasia (BPD) in premature infants under the new diagnostic criteria and establish a prediction model.MethodsIn this study, we retrospectively collected case data on preterm infants admitted to the NICU from August 2015 to August 2018. A lasso analysis was performed to identify the risk factors associated with the development of BPD. A nomogram predictive model was constructed in accordance with the new diagnostic criteria for BPD.ResultA total of 276 preterm infants were included in the study.The incidence of BPD under the 2018 diagnostic criteria was 11.2%.

The patent ductus arteriosus is a very common condition in preterm infants, and a hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. However, despite numerous randomized controlled trials, there is no consensus regarding management. Medical therapy is typically offered as first-line treatment, although it yields limited success and carries the potential for severe adverse events. In recent years, there has been rapid development in transcatheter patent ductus arteriosus closure primary with the use of the Amplatzer Piccolo Occluder, and this has gained widespread acceptance as a safe and effective alternative to surgical ligation in extremely low-birth-weight infants weighing over 700 g. This article aims to provide an appraisal of the patient selection process, a step-by-step procedural guide, and a comprehensive review of the outcomes associated with this approach.

Background. Neonatal thrombosis remains a complex and urgent challenge due to the presence of certain features of the hemostasis system in newborns and the variety of clinical signs. Management approaches are still under consideration, therapeutic experience of thrombolytic therapy (TLT) remains limited and requires benefit-risk assessment. Clinical case description. Clinical case of premature infant with multiple arterial thrombosis diagnosed on the 1st day of life is presented. Modern diagnostic features have allowed to establish the right diagnosis quickly and to start the treatment in time despite the similarities of clinical signs with congenital heart disease. Conclusion. TLT and heparin therapy have saved the child’s life, reversed ischemia, and preserved lower limbs from death. Doctors must perform dynamic monitoring during TLT to diagnose and correct hemorrhagic complications in timely manner.

This paper summarized the nursing practicve of a newborn with congenital bilateral chylothorax. The key points of nursing included intensive nursing management of airway, closed thoracic drainage nursing, correct evaluation of neonatal pain and corresponding nursing measures, nursing and observation of special medication, strict implementation of disinfection and isolation measures, and total parenteral and enteral nutrition nursing at the same time. After careful treatment and nursing, the newborn baby was cured and discharged on the 44th day of hospitalization.

Chinese Infectious Disease Surveillance of Pediatrics (ISPED) showed that in 2022, its resistance rate to meropenem was 18.5%. However, there is limited data available on the treatment of CRKP infection in neonates. In this study, we present a case involving a premature infant infected with OXA-48-producing Klebsiella pneumoniae. The combined susceptibility test revealed a significant synergistic effect between ceftazidime–avibactam(CAZ-AVI), and aztreonam(ATM). The infection was successfully treated with a combination of CAZ-AVI, ATM, and fosfomycin. This case represents the first reported instance of sepsis in a premature infant caused by OXA-48-producing Klebsiella pneumoniae in China. The objective of our study is to evaluate the effectiveness and safety of combination therapy in treating CRKP infections in premature infants. We hope that the findings of this study will provide valuable insights for clinicians in their treatment approach.Keywords: OXA-48, Klebsiella pneumoniae, premature infant, ceftazidime–avibactam, aztreonam

Necrotizing enterocolitis (NEC) is the leading cause of death caused by gastrointestinal disease in preterm infants. Major risk factors include prematurity, formula feeding, and gut microbial colonization. Microbes have been linked to NEC, yet there is no evidence of causal species, and select probiotics have been shown to reduce NEC incidence in infants. In this study, we evaluated the effect of the probiotic Bifidobacterium longum subsp. infantis (BL. infantis), alone and in combination with a human milk oligosaccharide (HMO)-sialylactose (3'SL)-on the microbiome, and the incidence of NEC in preterm piglets fed an infant formula diet. We studied 50 preterm piglets randomized between 5 treatments: (1) Preterm infant formula, (2) Donor human milk (DHM), (3) Infant formula + 3'SL, (4) Infant formula + BL. infantis, and (5) Infant formula and BL. infantis + 3'SL. NEC incidence and severity were assessed through the evaluation of tissue from all the segments of the GI tract. The gut microbiota composition was assessed both daily and terminally through 16S and whole-genome sequencing (WGS) of rectal stool samples and intestinal contents. Dietary BL. infantis and 3'SL supplementation had no effect, yet DHM significantly reduced the incidence of NEC. The abundance of BL. infantis in the gut contents negatively correlated with disease severity. Clostridium sensu stricto 1 and Clostridium perfringens were significantly more abundant in NEC and positively correlated with disease severity. Our results suggest that pre- and probiotics are not sufficient for protection from NEC in an exclusively formula-based diet. The results highlight the differences in microbial species positively associated with both diet and NEC incidence.
