Retrospective Observational Study of the Frequency and Interrelationships Among Neonatal Near Miss Criteria.

OBJECTIVE: To evaluate the frequency and interrelationships among neonatal near miss (NNM) criteria and the anticipated workload for audits in high-income countries. DESIGN: Observational retrospective descriptive study. SETTING: Tertiary maternal and neonatal units at Mater Mothers' Hospital, Brisbane, Queensland, Australia. PARTICIPANTS: Cases of stillbirths (n = 483), neonatal deaths (n = 203), and live births (n = 66,353) from January 2016 to July 2022 (N = 67,039). METHODS: We identified eight prespecified NNM criteria nominated by perinatal experts. Primary outcomes were NNM frequency, their interrelationships, and related workload. We used descriptive statistics and analysis of variance and considered p < .05 significant. RESULTS: We found 2,243 unique NNM cases (33.7/1,000 live births). The NNM ratio per 1,000 live births according to each of the eight criteria were: unplanned resuscitation at birth (25.09/1,000 live births), birth asphyxia needing surveillance for hypoxic ischemic encephalopathy (8.46/1,000 live births), metabolic acidosis at birth (8.04/1,000 live births), advanced resuscitation at birth (3.68/1,000 live births), seizures and/or stroke (0.96/1,000 live births), severe intraventricular hemorrhage and/or cerebellar hemorrhage (0.95/1,000 live births), moderate to severe hypoxic ischemic encephalopathy (0.9/1,000 live births), and severe birth trauma (0.44/1,000 live births). Almost one third of NNM cases met more than one criterion. Anticipated workload for monthly NNM audits varied from 0.04 to 2.8 cases per 1,000 live births. CONCLUSION: Different sets of NNM criteria considerably alter the frequency of NNMs and the anticipated workload for NNM audits. Their interrelationships are likely attributable to the fact that some of the criteria are risk factors for or are part of the causal pathway for other NNM criteria. These findings can assist with the determination of a pragmatic NNM definition considering the feasibility of NNM audits in high-income countries.

Newborn heart rate monitoring methods at birth and clinical outcomes: A systematic review.

Aim: Compare heart rate assessment methods in the delivery room on newborn clinical outcomes. Methods: A search of Medline, SCOPUS, CINAHL and Cochrane was conducted between January 1, 1946, to until August 16, 2023. (CRD 42021283438) Study Selection was based on predetermined criteria. Reviewers independently extracted data, appraised risk of bias and assessed certainty of evidence. Results: Two randomized controlled trials involving 91 newborns and 1 nonrandomized study involving 632 newborns comparing electrocardiogram (ECG) to auscultation plus pulse oximetry were included. No studies were found that compared any other heart rate measurement methods and reported clinical outcomes. There was no difference between the ECG and control group for duration of positive pressure ventilation, time to heart rate ≥ 100 beats per minute, epinephrine use or death before discharge. In the randomized studies, there was no difference in rate of tracheal intubation [RR 1.34, 95% CI (0.69-2.59)]. No participants received chest compressions. In the nonrandomized study, fewer infants were intubated in the ECG group [RR 0.75, 95% CI (0.62-0.90)]; however, for chest compressions, benefit or harm could not be excluded. [RR 2.14, 95% (CI 0.98-4.70)]. Conclusion: There is insufficient evidence to ascertain clinical benefits or harms associated with the use of ECG versus pulse oximetry plus auscultation for heart rate assessment in newborns in the delivery room.

Fast and accurate newborn heart rate monitoring at birth: A systematic review.

Aim: To examine speed and accuracy of newborn heart rate measurement by various assessment methods employed at birth. Methods: A search of Medline, SCOPUS, CINAHL and Cochrane was conducted between January 1, 1946, to until August 16, 2023. (CRD 42021283364) Study selection was based on predetermined criteria. Reviewers independently extracted data, appraised risk of bias and assessed certainty of evidence. Results: Pulse oximetry is slower and less precise than ECG for heart rate assessment. Both auscultation and palpation are imprecise for heart rate assessment. Other devices such as digital stethoscope, Doppler ultrasound, an ECG device using dry electrodes incorporated in a belt, photoplethysmography and electromyography are studied in small numbers of newborns and data are not available for extremely preterm or bradycardic newborns receiving resuscitation. Digital stethoscope is fast and accurate. Doppler ultrasound and dry electrode ECG in a belt are fast, accurate and precise when compared to conventional ECG with gel adhesive electrodes. Limitations: Certainty of evidence was low or very low for most comparisons. Conclusion: If resources permit, ECG should be used for fast and accurate heart rate assessment at birth. Pulse oximetry and auscultation may be reasonable alternatives but have limitations. Digital stethoscope, doppler ultrasound and dry electrode ECG show promise but need further study.

Evaluating multidimensional facets of the maternal experience after preterm birth.

OBJECTIVE: Describe self-relating (self-criticism, self-compassion) and parenting competence (satisfaction, self-efficacy) in mothers of children born preterm, and their associations with child characteristics, maternal sociodemographics at childbirth, and maternal concurrent well-being. STUDY DESIGN: The sample comprised 1926 biological mothers of 3- to18-year-old children born preterm with self-ratings on the standardized Forms of Self-Criticising/Attacking & Self-Reassuring Scale, Self-Compassion Scale, and Parenting Sense of Competence Scale. RESULTS: Mothers of children in early childhood reported significantly (p < 0.05) lower self-compassion than in middle childhood and adolescence. They also reported significantly lower parenting satisfaction than mothers of adolescents and higher self-efficacy than their middle childhood counterparts. Maternal psychosocial well-being was most strongly associated with self-compassion, parenting satisfaction, and self-efficacy after accounting for maternal psychopathology, child gestation, and child age. CONCLUSION: Longer-term associations of preterm birth with maternal self-relating and parenting competence emphasize broadening the scope of neonatal follow-up services, extending beyond child neurodevelopmental surveillance and postpartum psychopathology screening.

High-Dose Docosahexaenoic Acid in Newborns Born at Less Than 29 Weeks' Gestation and Behavior at Age 5 Years: Follow-Up of a Randomized Clinical Trial.

Importance: Children born at less than 29 weeks' gestation are at risk of behavioral difficulties. This may be due in part to the lack of transplacental supply of docosahexaenoic acid (DHA), a key fatty acid with structural and functional roles in the brain. Objective: To determine whether meeting the neonatal DHA requirement through supplementation is associated with improved behavioral functioning of children born at less than 29 weeks' gestation. Design, Setting and Participants: This was a follow-up of children from 10 Australian participating centers in a multi-center, blinded, parallel group randomized clinical trial of infants born at less than 29 weeks' gestation conducted from June 2012 and September 2015, excluding those with additional fatty acid supplementation or major congenital or chromosomal abnormalities. Follow-up took place from August 2018 to May 2021. Parents of surviving children who had not withdrawn from the original trial were invited to complete questionnaires when the child turned 5 years' corrected age. Interventions: Infants were randomized to receive daily enteral emulsions providing 60 mg/kg/d of DHA or a soy-oil emulsion (with no DHA) from within the first 3 days of enteral feeding until 36 weeks' postmenstrual age or discharge home, whichever occurred first. Main Outcomes and Measures: The primary outcome of this follow-up was parent-rated behavior and emotional functioning as indicated by the Total Difficulties score of the Strengths and Difficulties Questionnaire. Parents also completed questionnaires about their child's behavioral manifestations of executive functioning, as well as a range of health outcomes to assess potential longer-term side effects of DHA intervention. Results: Primary outcome data were available for 731 children (76% of 958 surviving eligible children; 361 in the intervention group and 370 in the control group). Of these 731, 452 (47%) were female, and the mean (SD) corrected age at follow-up was 5.4 (0.5) years. Following imputation for missing data, the mean Total Difficulties score was the same in both groups (intervention group, n = 465; mean [SD], 11.8 [6.3]; control group, n = 493; mean [SD], 11.8 [6.0]; mean difference adjusted for sex, gestational age stratum, and hospital, 0.01; 95% CI, -0.87 to 0.89; P = .98). There was no evidence for differences between the groups in any secondary outcomes of behavior, executive functioning, or health. Conclusions and Relevance: In this follow-up of a randomized clinical trial, enteral DHA supplementation at the equivalent of the estimated in utero dose for infants born at less than 29 weeks' gestation did not improve behavioral functioning at age 5 years. There were no indications of adverse effects with DHA supplementation. Trial Registration: Australian New Zealand Clinical Trial Registry: ACTRN12612000503820.

Risk profiles of the preterm behavioral phenotype in children aged 3 to 18 years.

Objective: Characterize the Preterm Behavioral Phenotype in children born preterm by identifying distinct profiles based on patterns of symptomatology or severity of the risk for attention-deficit/hyperactivity disorder, autism spectrum disorder, and anxiety, and determine their associations with child sex, gestational age, and chronological age. Methods: Sample comprised 2,406 children born preterm aged 3-18 years with primary caregiver behavioral ratings on the standardized Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Scale, Social Responsiveness Scale, and Preschool Anxiety Scale or Screen for Child Anxiety and Related Emotional Disorders. Results: Statistical fit indices of latent profile analysis supported a 3-profile model as optimal. Using this model, 75% of children born preterm were identified as having low expression, 20% moderate expression, and 5% high expression profiles of the Preterm Behavioral Phenotype described as co-occurring symptomatology of attention-deficit/hyperactivity disorder, autism spectrum disorder, and anxiety. Male children were more likely than females to be categorized in the moderate expression [Relative Risk Ratio (RRR) = 1.29, 95% CI = 1.05-1.59], and high expression profiles (RRR = 1.77, 95% CI = 1.17-2.66). Children born extremely preterm were more likely than those born moderate/late preterm to be categorized in the moderate expression (RRR = 1.68, 95% CI = 1.30-2.19) and high expression profiles (RRR = 2.06, 95% CI = 1.31-3.25). Finally, those in the school-age (RRR = 1.68, 95% CI = 1.32-2.14; RRR = 1.95, 95% CI = 1.21-3.13), early adolescence (RRR = 1.85, 95% CI = 1.38-2.48; RRR = 2.61, 95% CI = 1.53-4.44) and late adolescence (RRR = 2.09, 95% CI = 1.38-3.19; RRR = 2.28, 95% CI = 1.02-5.08) periods were more likely than those in the preschool period to be categorized in the moderate and high expression profiles, respectively. Conclusion: A quarter of children born preterm were at elevated risk for manifesting symptomatology across all three domains of the Preterm Behavioral Phenotype. Findings emphasize accounting for symptom co-occurrence of this phenotype in neurodevelopmental follow-up and psychosocial interventions to optimize child outcomes.

Exhaled CO2 monitoring to guide non-invasive ventilation at birth: a systematic review.

OBJECTIVE: Measuring exhaled carbon dioxide (ECO2) during non-invasive ventilation at birth may provide information about lung aeration. However, the International Liaison Committee on Resuscitation (ILCOR) only recommends ECO2 detection for confirming endotracheal tube placement. ILCOR has therefore prioritised a research question that needs to be urgently evaluated: 'In newborn infants receiving intermittent positive pressure ventilation by any non-invasive interface at birth, does the use of an ECO2 monitor in addition to clinical assessment, pulse oximetry and/or ECG, compared with clinical assessment, pulse oximetry and/or ECG only, decrease endotracheal intubation in the delivery room, improve response to resuscitation, improve survival or reduce morbidity?'. DESIGN: Systematic review of randomised and non-randomised studies identified by Ovid MEDLINE, Embase and Cochrane CENTRAL search until 1 August 2022. SETTING: Delivery room. PATIENTS: Newborn infants receiving non-invasive ventilation at birth. INTERVENTION: ECO2 measurement plus routine assessment compared with routine assessment alone. MAIN OUTCOME MEASURES: Endotracheal intubation in the delivery room, response to resuscitation, survival and morbidity. RESULTS: Among 2370 articles, 23 were included; however, none had a relevant control group. Although studies indicated that the absence of ECO2 may signify airway obstruction and ECO2 detection may precede a heart rate increase in adequately ventilated infants, they did not directly address the research question. CONCLUSIONS: Evidence to support the use of an ECO2 monitor to guide non-invasive positive pressure ventilation at birth is lacking. More research on the effectiveness of ECO2 measurement in addition to routine assessment during non-invasive ventilation of newborn infants at birth is needed.

Within- and between-twin comparisons of risk for childhood behavioral difficulties after preterm birth.

BACKGROUND: Preterm birth and multiple gestation are independently associated with adverse neurodevelopmental outcomes. The objective of this study was to describe risks of screening positive for attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and anxiety in preterm-born twin children by zygosity (monozygotic, dizygotic) and birth order (first-born, second-born). METHODS: Caregivers of 349 preterm-born twin pairs (42% monozygotic) aged 3-18 years reported child behavioral outcomes on Strengths and Weaknesses of ADHD Symptoms and Normal Behavior; Social Responsiveness Scale, Second Edition; and Preschool Anxiety Scale or Screen for Child Anxiety and Related Emotional Disorders. RESULTS: Concordance for behavioral outcomes in twin pairs ranged from 80.06 to 89.31% for ADHD, 61.01 to 84.23% for ASD, and 64.76 to 73.35% for anxiety. Monozygotic twins had a greater risk than dizygotic of screening positive for inattention (risk ratio = 2.91, 95% CI = 1.48-5.72) and social anxiety (1.79, 1.23-2.61). Relative to first-born, second-born twins had a greater risk of screening positive for hyperactivity/impulsivity (1.51, 1.06-2.16); overall ASD (2.38, 1.62-3.49); difficulties with social awareness (2.68, 1.94-3.71), social cognition (4.45, 3.06-6.46), and social communication (2.36, 1.56-3.57); restricted/repetitive behavior (1.91, 1.30-2.81); overall anxiety (1.34, 1.10-1.64); generalized anxiety (1.34, 1.11-1.60); and social anxiety (1.32, 1.06-1.64). CONCLUSION: The current findings emphasize considering zygosity and birth order in preterm and multiple birth outcomes research, and highlight clinical implications for discharge planning, neurodevelopmental surveillance, and facilitating parenting and family support. IMPACT: Zygosity and birth order are important determinants of behavioral and socioemotional outcomes in preterm-born twins. Among 349 preterm-born twin pairs aged 3-18 years (42% monozygotic), 61-89% demonstrated concordance for behavioral and socioemotional outcomes. Monozygosity had greater risks than dizygosity for positive screening of inattention and social anxiety. Second-born twins had greater risks than first-born for hyperactivity/impulsivity, social difficulties (awareness, cognition, communication), restricted/repetitive behavior, and anxiety (generalized, social). These findings have implications for discharge planning, neurodevelopmental surveillance, and facilitating parenting and family support.

Smell and taste of milk during tube feeding of preterm infants: neurodevelopmental follow-up of the randomized TASTE trial, study protocol.

BACKGROUND: The Taste And Smell To Enhance nutrition (TASTE) trial investigated the effects of smell and taste of milk with tube feeding compared to routine care on the growth of preterm infants. There was no difference between groups in growth (weight, head circumference, length) z-scores at discharge from the hospital. Infants in the intervention group had higher head circumference and length z-scores at 36 weeks postmenstrual age, both secondary outcomes. The objective of this follow-up study is to assess 2-year neurodevelopmental and growth outcomes after exposure of preterm infants to the smell and taste of milk with tube feeding compared to routine care. METHODS: This is a neurodevelopmental follow-up study of a two-center, placebo-controlled randomized trial. Infants born before 29 weeks postmenstrual age and/or with a birth weight of less than 1250 g were randomized to smell and taste of milk with each tube feed or routine care. The current follow-up assessed the 2-year neurodevelopmental and growth outcomes of participants of the TASTE trial discharged from the hospital (n = 334). The primary outcome is survival free of any major neurodevelopmental impairment comprising any moderate/severe cerebral palsy (Gross Motor Function Classification System score II-V), Bayley Scales of Infant and Toddler Development, Third/Fourth Edition (Bayley-III/Bayley-4) motor, cognitive, or language scores < -2SD, blindness, or deafness at 2 years of age. Other outcomes include death, breastfeeding within the first year, and respiratory support, oral feeding, and anthropometric parameters at 2 years of age. The Human Research Ethics Committees of Mater Misericordiae Limited and the Royal Women's Hospital approved the TASTE trial including the neurodevelopmental follow-up described in this protocol. DISCUSSION: For patients and their families, the neurodevelopmental outcomes of preterm infants are of utmost importance. Consequently, they should be investigated following any interventional study performed during the newborn period. Furthermore, improved weight gain and head growth in the hospital are associated with better long-term neurodevelopmental outcomes. Smelling and tasting of milk is an uncomplicated and cost-effective intervention that may improve the growth and neurodevelopmental outcomes of preterm infants. Potential limitations affecting this follow-up study, caused by the COVID-19 pandemic, are anticipated and discussed in this protocol.

Recommended Guideline for Uniform Reporting of Neonatal Resuscitation: The Neonatal Utstein Style.

Clinical research on neonatal resuscitation has accelerated over recent decades. However, an important methodologic limitation is that there are no standardized definitions or reporting guidelines for neonatal resuscitation clinical studies. To address this, the International Liaison Committee on Resuscitation Neonatal Life Support Task Force established a working group to develop the first Utstein-style reporting guideline for neonatal resuscitation. The working group modeled this approach on previous Utstein-style guidelines for other populations. This reporting guideline focuses on resuscitation of newborns immediately after birth for respiratory failure, bradycardia, severe bradycardia, or cardiac arrest. We identified 7 relevant domains: setting, patient, antepartum, birth/preresuscitation, resuscitation process, postresuscitation process, and outcomes. Within each domain, relevant data elements were identified as core versus supplemental. Core data elements should be collected and reported for all neonatal resuscitation studies, while supplemental data elements may be collected and reported using standard definitions when possible. The Neonatal Utstein template includes both core and supplemental elements across the 7 domains, and the associated Data Table provides detailed information and reporting standards for each data element. The Neonatal Utstein reporting guideline is anticipated to assist investigators engaged in neonatal resuscitation research by standardizing data definitions. The guideline will facilitate data pooling in meta-analyses, enhancing the strength of neonatal resuscitation treatment recommendations and subsequent guidelines.

Early brain morphometrics from neonatal MRI predict motor and cognitive outcomes at 2-years corrected age in very preterm infants.

Infants born very preterm face a range of neurodevelopmental challenges in cognitive, language, behavioural and/or motor domains. Early accurate identification of those at risk of adverse neurodevelopmental outcomes, through clinical assessment and Magnetic Resonance Imaging (MRI), enables prognostication of outcomes and the initiation of targeted early interventions. This study utilises a prospective cohort of 181 infants born <31 weeks gestation, who had 3T MRIs acquired at 29-35 weeks postmenstrual age and a comprehensive neurodevelopmental evaluation at 2 years corrected age (CA). Cognitive, language and motor outcomes were assessed using the Bayley Scales of Infant and Toddler Development - Third Edition and functional motor outcomes using the Neuro-sensory Motor Developmental Assessment. By leveraging advanced structural MRI pre-processing steps to standardise the data, and the state-of-the-art developing Human Connectome Pipeline, early MRI biomarkers of neurodevelopmental outcomes were identified. Using Least Absolute Shrinkage and Selection Operator (LASSO) regression, significant associations between brain structure on early MRIs with 2-year outcomes were obtained (r = 0.51 and 0.48 for motor and cognitive outcomes respectively) on an independent 25% of the data. Additionally, important brain biomarkers from early MRIs were identified, including cortical grey matter volumes, as well as cortical thickness and sulcal depth across the entire cortex. Adverse outcome on the Bayley-III motor and cognitive composite scores were accurately predicted, with an Area Under the Curve of 0.86 for both scores. These associations between 2-year outcomes and patient prognosis and early neonatal MRI measures demonstrate the utility of imaging prior to term equivalent age for providing earlier commencement of targeted interventions for infants born preterm.

Current approach and attitudes toward neonatal near-miss and perinatal audits: An exploratory international survey.

BACKGROUND: Combined with perinatal mortality review, neonatal near-miss (NNM) audit has the potential to inform strategies to better prevent adverse perinatal outcomes. Nonetheless, there is lack of standardised definitions of NNM and limited evidence of implementation of NNM audits. AIM: To describe definitions of NNM and assess current approaches and attitudes toward perinatal mortality and morbidity audit. MATERIALS AND METHODS: Online survey from December 2021 to February 2022, with a mix of Likert scales, polar, pool, multi-choice, and open-ended questions, disseminated through national and international organisations to perinatal healthcare workers from high-income countries. RESULTS: One hundred and twenty participants came from Australia (n = 86), New Zealand (n = 18), Canada (n = 7), USA (n = 4), Netherlands (n = 2), other countries (n = 3). Neonatologists (35%), midwives (21.7%), obstetricians (12.5%), neonatal nurse practitioners (11.7%) and others (23.3%) responded. Most respondents thought the main characteristics to define NNM were birth asphyxia needing therapeutic hypothermia (68.3%), unexpected resuscitation at birth (67.5%), need for intubation/chest compression/adrenaline (65.0%) and metabolic acidosis at birth (60.0%). There were 97.5% of participants who considered NNM important for identifying cases for perinatal morbidity audits. However, only 10.0% of their institutions used a NNM definition. Overall, 98.4% of participants considered perinatal mortality and morbidity audits important to prevent adverse outcomes. CONCLUSION: Neonatal near-miss audit is viewed as a valuable tool to reduce adverse neonatal outcomes. There was reasonable consensus that NNM encompassed evidence of birth asphyxia and/or advanced neonatal resuscitation. Data from this international survey identifies a starting point for a consensus definition of NNM, which can be used for perinatal audits to identify opportunities for improvement.

Evaluating enhanced pulse oximetry auditory displays for neonatal oxygen targeting: A randomized laboratory trial with clinicians and non-clinicians.

Standard pulse oximeter auditory tones do not clearly indicate departures from the target range of oxygen saturation (SpO2) of 90%-95% in preterm neonates. We tested whether acoustically enhanced tones would improve participants' ability to identify SpO2 range. Twenty-one clinicians and 23 non-clinicians used (1) standard pulse oximetry variable-pitch tones plus alarms; (2) beacon-enhanced tones without alarms in which reference tones were inserted before standard pulse tones when SpO2 was outside target range; and (3) tremolo-enhanced tones without alarms in which pulse tones were modified with tremolo when SpO2 was outside target range. For clinicians, range identification accuracies (mean (SD)) in the standard, beacon, and tremolo conditions were 52% (16%), 73% (14%) and 76% (13%) respectively, and for non-clinicians 49% (16%), 76% (13%) and 72% (14%) respectively, with enhanced conditions always significantly more accurate than standard. Acoustic enhancements to pulse oximetry clearly indicate departures from preterm neonates' target SpO2 range.
