Caesarean section and respiratory system disorders in newborns. Eur J Obstet Gynecol Reprod Biol X 2024; 23:100336.

Abstract
Cesarean section (C-section) delivery is associated with a higher risk of respiratory problems in newborns, particularly if performed electively at 37 weeks. This risk is greater than with spontaneous or induced labor but diminishes as gestation advances. To lower the incidence of respiratory issues in newborns, it is vital to promote natural labor, avoid unnecessary C-sections, and offer thorough prenatal care. Healthcare providers and expectant mothers should assess the risks and benefits of elective C-sections carefully. By advocating for natural labor and reducing unnecessary C-sections, the occurrence of respiratory problems in newborns can be decreased. Adequate prenatal care and monitoring are crucial for identifying and managing potential risk factors for respiratory diseases in newborns. It is crucial for healthcare professionals to educate expectant mothers about the risks of elective C-sections and the advantages of allowing labor to progress naturally. By fostering transparent communication and collaborative decision-making between healthcare providers and pregnant women, well-informed choices can be made that prioritize the health of both the mother and the baby. Furthermore, ongoing research and advancements in medical technology can improve our understanding of how delivery methods affect newborn respiratory health, ultimately leading to better outcomes and care practices in the future.

Abstract
Neonatal respiratory distress syndrome (NRDS) is one of the leading causes of neonatal mortality in low-income countries. It is caused by a lack of surface-active substances in the lungs, and the maternal inflammatory response plays an important role in the formation of surface-active substances in the fetal lungs. We aimed to investigate the correlation between maternal prenatal systemic inflammatory indices and respiratory distress syndrome in preterm neonates. This is a retrospective case-control study that collected data from all patients who delivered between 28 and 36 weeks of gestation at Longhua District People's Hospital in Shenzhen City and whose infants were admitted to the neonatal unit, newborns with respiratory distress syndrome were in the experimental group (NRDS group), and newborns without NRDS were in the control group (non-NRDS group). To minimize the effect of confounders on the results, propensity score matching was performed on baseline characteristics. Totally, 524 patients were included (93 in the NRDS group and 431 in the non-NRDS group), and 71 matched pairs (142 patients). The neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), aggregate index of systemic inflammation (AISI) and neutrophil lymphocyte to platelet ratio (NLPR) were higher in the NRDS group than in the non-NRDS group (p < 0.05). The ROC curves of NLR, dNLR, SII, SIRI, AISI and NLPR for the diagnosis of NRDS were plotted, and it was found that the combined diagnostic efficacy of these six systemic inflammatory markers was better (AUC: 0.643, P = 0.003). Patients were divided into two groups based on the cut-off values determined from the ROC curves, and analysis using binary regression models revealed that SII ≥ 1199.94 (OR, 2.554; 95% CI 1.245-5.239, P = 0.011) and NLPR ≥ 0.0239 (OR, 2.175; 95% CI 1.061-4.459, P = 0.034) were independent risk factors predicting NRDS. Maternal prenatal SII ≥ 1199.94 and NLPR ≥ 0.0239 are independent risk factors for NRDS, and clinicians may be used to prevent neonatal respiratory distress in advance to reduce the incidence of NRDS.

Abstract
OBJECTIVE To evaluate if antenatal steroid use was associated with a lower rate of respiratory complications in neonates born late preterm to patients with pregestational diabetes mellitus (PGDM). METHODS This was a retrospective cohort study of live, singleton, non-anomalous, late preterm births complicated by PGDM using data from the Centers for Disease Control and National Vital Statistics System from 2017 to 2021. The primary (assisted ventilation use >6 h) and secondary neonatal outcomes (immediate assisted ventilation, Apgar score, neonatal intensive care unit [NICU] admission, and surfactant use) were compared between births that received steroids and those that did not. Multivariable analyses were performed to adjust for differences in demographic and clinical characteristics. RESULTS There were 24 323 late preterm births with PGDM, of which 4613 received antenatal steroids and 19 710 did not receive steroids. After adjusting for the differences among the two groups, the need for assisted neonatal ventilation for more than 6 h (adjusted odds ratio [aOR] 1.69, 95% confidence interval [CI] 1.53-1.86), immediate assisted neonatal ventilation (aOR 1.67, 95% CI 1.55-1.80), NICU admission (aOR 1.95, 95% CI 1.81-2.10), and surfactant use (aOR 1.68, 95% CI 1.40-2.02) were higher in the births that received steroids compared with those that did not. These findings did not differ when examining outcomes at each gestational week of delivery between 34 weeks 0 days and 36 weeks 6 days. CONCLUSIONS Antenatal steroid use in late preterm births complicated with PGDM was associated with worse immediate respiratory neonatal outcomes. Our findings support current recommendations against the use of steroids in the late preterm period in pregnancies with PGDM.

Abstract
OBJECTIVE Initial surfactant studies demonstrated improvements in survival and need for respiratory support. However, as the use of non-invasive respiratory support has increased the use of surfactant has decreased. We examined in a contemporary cohort of BPD patients if surfactant use was associated with BPD severity. STUDY DESIGN An observational study using data from the BPD Collaborative Registry. RESULTS 971 infants with BPD met entry criteria, 864 (89%) had received surfactant in the first 72 h of life (SURF) and the remainder had not (no surfactant). There was an association between SURF and BPD grade, with a greater likelihood of grade 3 BPD in infants who received surfactant in the DR or who had 2 or more doses. CONCLUSIONS We speculate that the use of surfactant in the DR and use of multiple doses reflect the impact of perinatal factors beyond immaturity alone that increase the risk for grade 3 BPD.

Abstract
Respiratory diseases are one of the leading causes of death and disability around the world. Mice are commonly used as models of human respiratory disease. Phenotypic analysis of mice with spontaneous, congenital, inherited, or treatment-related respiratory tract abnormalities requires investigators to discriminate normal anatomic features of the respiratory system from those that have been altered by disease. Many publications describe individual aspects of normal respiratory tract development, primarily focusing on morphogenesis of the trachea and lung. However, a single reference providing detailed low- and high-magnification, high-resolution images of routine hematoxylin and eosin (H&E)-stained sections depicting all major structures of the entire developing murine respiratory system does not exist. The purpose of this atlas is to correct this deficiency by establishing one concise reference of high-resolution color photomicrographs from whole-slide scans of H&E-stained tissue sections. The atlas has detailed descriptions and well-annotated images of the developing mouse upper and lower respiratory tracts emphasizing embryonic days (E) 9.0 to 18.5 and major early postnatal events. The selected images illustrate the main structures and events at key developmental stages and thus should help investigators both confirm the chronological age of mouse embryos and distinguish normal morphology as well as structural (cellular and organ) abnormalities.

Abstract
Background: Respiratory problems are frequent in newborns, and are mainly studied with chest X-rays, whereas CT scans are usually needed for the evaluation of rare malformations and diseases. Lung ultrasound (LUS] has been proposed as an alternative method of diagnosing a variety of respiratory conditions. In recent years, there has been a rapid increase in LUS studies, thanks to the ability of LUS to rapidly exclude complications and significantly reduce radiation exposure in this fragile population. We aimed to summarize the current knowledge about LUS. Methods: A literature search was conducted on the Medline and Cochrane databases using appropriate terms. The inclusion criteria were: English language and human species. Exclusion criteria were: non-English language, animal species, case reports, case series, non-systematic reviews, and editorials. Results: The search returned 360 results. No Cochrane reviews were found. Titles and abstracts were screened, and 37 were finally considered. Studies concerning the use of lung ultrasound for the following conditions were presented: neonatal respiratory distress syndrome, transient tachypnea of the newborn, pneumothorax, pulmonary hemorrhage, pneumonia, bronchopulmonary dysplasia, and prediction of extubation success. Conclusions: We discussed the utility of LUS for the diagnosis and treatment of neonatal diseases according to the most recent literature.

Abstract
BACKGROUND As a rule, newborns do not require special medical care. If unexpected complications occur peripartum or postpartum, support from and transport to specialised neonatal hospitals might be needed. METHODS In a retrospective study, all transport protocols of a supraregional paediatric‑neonatological maximum care hospital in northwestern Germany from 01.10.2018 through 30.09.2021 were analysed. The particular focus was on transports of newborns (<7 days) and the leading symptoms that led to contact. RESULTS A total of 299 patients were included (average age of 15.4 h, 61.6 % males). The average complete transport time was approximately 2 h. Five leading neonatal diseases (respiratory, infectious, asphyxia, cardiac, haematological) were found to represent the causes of >80 % of transfers. Respiratory adaptation disorders are the main reason for transferring a newborn to a centre, whereas asphyxia is the most severe condition. The various symptoms differ in their time of onset, a factor which must be taken into account in practice. Differences were also found between different types of hospitals: while a large proportion of transports were carried out from maternity hospitals (80.6 %), children transported from children's hospitals were generally more severely ill. DISCUSSION Transfers of neonates, especially from maternity hospitals to neonatal intensive care units due to special neonatal diseases, are not rare. In times of increasingly scarce resources, the effective care of sick or at-risk neonates is essential. For low-population regions, this means professional cooperation between maximum care providers and smaller children's hospitals and maternity-only hospitals.

Abstract
Fetal lung development is a crucial and complex process that lays the groundwork for postnatal respiratory health. However, disruptions in this delicate developmental journey can lead to fetal lung development disorders, impacting neonatal outcomes and potentially influencing health outcomes well into adulthood. Recent research has shed light on the intriguing association between fetal lung development disorders and the development of adult diseases. Understanding these links can provide valuable insights into the developmental origins of health and disease, paving the way for targeted preventive measures and clinical interventions. This review article aims to comprehensively explore the association of fetal lung development disorders with adult diseases. We delve into the stages of fetal lung development, examining key factors influencing fetal lung maturation. Subsequently, we investigate specific fetal lung development disorders, such as respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), congenital diaphragmatic hernia (CDH), and other abnormalities. Furthermore, we explore the potential mechanisms underlying these associations, considering the role of epigenetic modifications, transgenerational effects, and intrauterine environmental factors. Additionally, we examine the epidemiological evidence and clinical findings linking fetal lung development disorders to adult respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), and other respiratory ailments. This review provides valuable insights for healthcare professionals and researchers, guiding future investigations and shaping strategies for preventive interventions and long-term care.

Abstract
Neonatal respiratory failure (NRF) is an emergency which has not been examined extensively. We critically synthesized the contemporary in-hospital prevalence, mortality rate, predictors, aetiologies, diagnosis and management of NRF to better formulate measures to curb its burden. We searched MEDLINE and Google Scholar from 01/01/1992 to 31/12/2022 for relevant publications. We identified 237 papers from 58 high-income and low-and middle-income countries (LMICs). NRF prevalence ranged from 0.64 to 88.4% with some heterogeneity. The prevalence was highest in Africa, the Middle East and Asia. Globally as well as in Asia and the Americas, respiratory distress syndrome (RDS) was the leading aetiology of NRF. Neonatal sepsis was first aetiology in Africa, whereas in both Europe and the Middle East it was transient tachypnoea of the newborn. Independent predictors of NRF were prematurity, male gender, ethnicity, low/high birth weight, young/advanced maternal age, primiparity/multiparity, maternal smoking, pregestational/gestational diabetes mellitus, infectious anamneses, antepartum haemorrhage, gestational hypertensive disorders, multiple pregnancy, caesarean delivery, antenatal drugs, foetal distress, APGAR score, meconium-stained amniotic fluid and poor pregnancy follow-up. The NRF-related in-hospital mortality rate was 0.21-57.3%, highest in Africa, Asia and the Middle East. This death toll was primarily due to RDS globally and in all regions. Clinical evaluation using the Silverman-Anderson score was widely used and reliable. Initial resuscitation followed by specific management was the common clinical practice. CONCLUSION NRF has a high burden globally, driven by RDS, especially in LIMCs where more aggressive treatment and innovations, preferably subsidized, are warranted to curb its alarming burden. WHAT IS KNOWN • Neonatal respiratory failure is a frequent emergency associated with a significant morbidity and mortality, yet there is no comprehensive research paper summarizing its global burden. • Neonatal respiratory failure needs prompt diagnosis and treatment geared at improving neonatal survival. WHAT IS NEW • Neonatal respiratory failure has an alarmingly high global burden largely attributed to Respiratory distress syndrome. Low resource settings are disproportionately affected by the burden of neonatal respiratory failure. • Independent preditors of neonatal respiratory failure are several but can be classified into foetal, maternal and obstetrical factors. An illustrative pedagogical algorithm is provided to facilitate diagnosis and management of neonatal respiratory failure by healthcare providers.

Objective We conducted a systematic review to investigate electroencephalography (EEG) changes during periods of acute respiratory events such as apnoea and the effect of respiratory stimulants on EEG features in infants. Methods Studies examining respiration and EEG-recorded brain activity in human neonates between 28 and 42 weeks postmenstrual age were included. Two reviewers independently screened all records and included studies were assessed using the Joanna Briggs Institute Critical Appraisal Tool. The protocol was registered in PROSPERO (CRD42022339873). Results We identified 14 studies with a total of 534 infants. Nine articles assessed EEG changes in relation to apnoea, one assessed hiccups, and four investigated the effect of respiratory stimulants. The relationship between neonatal apnoea and EEG changes was inconsistent; EEG suppression and decreased amplitude and frequency were observed during some, but not all, apnoeas. Respiratory stimulants increased EEG continuity compared with before use. Conclusions Current studies in this area are constrained by small sample sizes. Diverse exposure definitions and outcome measures impact inference. Significance This review highlights the need for further work; understanding the relationship between respiration and the developing brain is key to mitigating the long-term effects of apnoea.

Developing a model to predict neonatal respiratory distress syndrome and affecting factors using data mining: A cross-sectional study. Int J Reprod Biomed 2023; 21:909-920. [PMID: 38292513 PMCID: PMC10823121 DOI: 10.18502/ijrm.v21i11.14654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 08/11/2023] [Accepted: 10/26/2023] [Indexed: 02/01/2024] Open
Abstract
Background: One of the major challenges that hospitals and clinicians face is the early identification of newborns at risk for adverse events. One of them is neonatal respiratory distress syndrome (RDS). RDS is the widest spared respiratory disorder in immature newborns and the main source of death among them. Machine learning has been broadly accepted and used in various scopes to analyze medical information and is very useful in the early detection of RDS. Objective: This study aimed to develop a model to predict neonatal RDS and affecting factors using data mining. Materials and Methods: The original dataset in this cross-sectional study was extracted from the medical records of newborns diagnosed with RDS from July 2017-July 2018 in Alzahra hospital, Tabriz, Iran. This data includes information about 1469 neonates, and their mothers information. The data were preprocessed and applied to expand the classification model using machine learning techniques such as support vector machine, Naïve Bayes, classification tree, random forest, CN2 rule induction, and neural network, for prediction of RDS episodes. The study compares models according to their accuracy. Results: Among the obtained results, an accuracy of 0.815, sensitivity of 0.802, specificity of 0.812, and area under the curve of 0.843 was the best output using random forest. Conclusion: The findings of our study proved that new approaches, such as data mining, may support medical decisions, improving diagnosis in neonatal RDS. The feasibility of using a random forest in neonatal RDS prediction would offer the possibility to decrease postpartum complications of neonatal care.

Abstract
Background Continuous monitoring of vital signs and other biological signals in the Neonatal Intensive Care Unit (NICU) requires sensors connected to the bedside monitors by wires and cables. This monitoring system presents challenges such as risks for skin damage or infection, possibility of tangling around the patient body, or damage of the wires, which may complicate routine care. Furthermore, the presence of cables and wires can act as a barrier for parent-infant interactions and skin to skin contact. This study will investigate the use of a new wireless sensor for routine vital monitoring in the NICU. Methods Forty-eight neonates will be recruited from the Montreal Children's Hospital NICU. The primary outcome is to evaluate the feasibility, safety, and accuracy of a wireless monitoring technology called ANNE® One (Sibel Health, Niles, MI, USA). The study will be conducted in 2 phases where physiological signals will be acquired from the standard monitoring system and the new wireless monitoring system simultaneously. In phase 1, participants will be monitored for 8 h, on four consecutive days, and the following signals will be obtained: heart rate, respiratory rate, oxygen saturation and skin temperature. In phase 2, the same signals will be recorded, but for a period of 96 consecutive hours. Safety and feasibility of the wireless devices will be assessed. Analyses of device accuracy and performance will be accomplished offline by the biomedical engineering team. Conclusion This study will evaluate feasibility, safety, and accuracy of a new wireless monitoring technology in neonates treated in the NICU.

Abstract
PURPOSE We aimed to investigate respiratory rate variability (RRV) and tidal volume (Vt) variability during exposure to normobaric hypoxia (i.e., reduction in the fraction of inspired oxygen - FiO2), and the association of the changes in RRV and Vt variability with the changes in pulse oxygen saturation (SpO2). METHODS Thirty healthy human participants (15 females) were exposed to: (1) 15-min normoxia, (2) 10-min hypoxia simulating 2200m, (3) 10-min hypoxia simulating 4000m, (4) 10-min hypoxia simulating 5000m, (5) 15-min recovery in normoxia. Linear regression modelling was applied with SpO2 (dependent variable) and the changes in RRV and Vt variability (independent variables), controlling for FiO2, age, sex, changes in heart rate (HR), changes in HR variability (HRV), and changes in minute ventilation (VE). RESULTS When modelling breathing parameter variability as root-mean-square standard deviation (RMSSD), a significant independent association of the changes in RRV with the changes in SpO2 was found (B=-4.3e-04, 95% CI=-8.3e-04/-2.1e-05, p=0.04). The changes in Vt variability showed no significant association with the changes in SpO2 (B=-1.6, 95% CI=-5.5/2.4, p=0.42). When modelling parameters variability as SD, a significant independent association of the changes in RRV with the changes in SpO2 was found (B=-8.2e-04, 95% CI=-1.5e-03/-9.4e-05, p=0.03). The changes in Vt variability showed no significant association with the changes in SpO2 (B=1.4, 95% CI=-5.8/8.6, p=0.69). CONCLUSION Higher RRV is independently associated with lower SpO2 during acute hypoxic exposure, while Vt variability parameters are not. Therefore, RRV may be a potentially interesting parameter to characterize individual responses to acute hypoxia.

Abstract
Pre- and postnatal factors influence the formation of the newborn's microbiome as early as birth and the intrauterine period has a substantial impact on the composition of the baby's gastrointestinal microbiota and its subsequent development. This study intends to measure pregnant women's knowledge of the importance of microbiota for the health of the newborn. The sample was selected based on defined inclusion and exclusion criteria. The assessment of women's knowledge was assessed by the Kolmogorov-Smirnov and Kruskal-Wallis statistical tests. This study population comprised 291 adult pregnant women with a mean age of 28.4 ± 4.7 years. A total of 34% (n = 99), 35% (n = 101), and 31.3% (n = 91) were at the 1-3 trimester, respectively. The results showed that 36.4% of the women were aware that the intrauterine period changes the makeup of the gastrointestinal microbiota, whereas 5.8% exhibited awareness of the composition of the child's normal gut microbiota. Most of the women surveyed-(72.1%)-know that colonization of the tract occurs as early as the birth period. Women with student status (those who will pursue higher education in the future) and those who had given birth to the most children exhibited higher levels of knowledge.

Lung Ultrasound Role in Diagnosis of Neonatal Respiratory Disorders: A Prospective Cross-Sectional Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10010173.

Abstract
Lung ultrasound (LUS) has become one of the most exciting applications in neonatal point-of-care ultrasound (POCUS), yet still lacks routine clinical use. This study assesses the utility of LUS for neonatal respiratory disorders (NRDs) diagnosis and follow-up compared to chest X-ray (CXR). A prospective cross-sectional study was conducted on 100 neonates having NRDs with a gestational age ≥28 weeks, excluding those having multiple congenital anomalies, chromosomal aberrations, hydrops fetalis and/or heart failure. CXR and LUS were done on admission for diagnosis and were repeated after 7 days, or if needed earlier within the 7 days. The diagnosis of NRDs by CXR and LUS on admission and after 7 days was comparable (p > 0.05). LUS diagnosis sensitivity and specificity for respiratory distress syndrome, pneumonia, meconium aspiration syndrome, pneumothorax and pulmonary atelectasis were 94.7/100%, 97.5/95%, 92.3/100%, 90.9/98.9% and 100/97.8%, respectively. The total agreement between LUS and CXR was 98.5% with 95% CI (0.88 to 0.92). LUS and CXR had considerable agreement in the diagnosis of NRDs. Being a reliable bedside modality of diagnosis and safer than CXR, LUS may be considered an alternative method for the diagnosis of neonates with NRDs.

Abstract
BACKGROUND/AIMS Phthalates and their replacements are endocrine/metabolic disruptors that may impact gestational weight gain (GWG) - a pregnancy health indicator. We investigated overall and fetal sex-specific associations of individual and cumulative phthalate/replacement biomarkers with GWG. METHODS Illinois women (n = 299) self-reported their weight pre-pregnancy and at their final obstetric appointment before delivery (median 38 weeks). We calculated pre-pregnancy body mass index and gestational age-specific GWG z-scores (GWGz). We quantified 19 phthalate/replacement metabolites (representing 10 parent compounds) in pools of up-to-five first-morning urine samples, collected approximately monthly between 8 and 40 weeks gestation. We used linear regression, quantile-based g-computation (QGComp), and weighted quantile sum regression (WQSR) to evaluate associations of ten biomarkers (individual metabolites or parent molar-sums) individually or as mixtures (in interquartile range intervals) with GWGz. We evaluated associations in all women and stratified by fetal sex. RESULTS Individually, sums of metabolites of di(2-ethylhexyl) phthalate (ƩDEHP), di(isononyl) cyclohexane-1,2-dicarboxylate (ƩDiNCH), and di(2-ethylhexyl) terephthalate (ƩDEHTP) had consistent inverse associations with GWGz, and some associations were fetal sex-specific. When evaluating phthalates/replacements as a mixture, QGComp identified ƩDEHP, ƩDEHTP, and mono-(3-carboxypropyl) phthalate, along with sum of di(isononyl) phthalate metabolites (ƩDiNP) and monobenzyl phthalate as notable contributors to lower and higher GWGz, respectively, resulting in a marginal inverse joint association in all women (β: -0.29; 95% CI: -0.70, 0.12). In women carrying females, ƩDEHP contributed to the marginal inverse joint association (β: -0.54; 95% CI: -1.09, 0.03). However, there was no overall association in women carrying males (β: 0.00; 95% CI: -0.60, 0.59), which was explained by approximately equal negative (driven by ƩDEHTP) and positive (driven by ƩDiNP) partial associations. WQSR analyses consistently replicated these QGComp findings. CONCLUSIONS Biomarkers of phthalates/replacements were fetal sex-specifically associated with GWGz. Because ƩDEHTP contributed substantively to mixture associations, additional studies in pregnant women may be needed around this plasticizer replacement.

Abstract
OBJECTIVES Accurate and timely diagnosis of common neonatal conditions is crucial for reducing neonatal deaths. In low/middle-income countries with limited resources, there is sparse information on how neonatal diagnoses are made. The aim of this study was to describe the diagnostic criteria used for common conditions in neonatal units (NNUs) in Nigeria and Kenya. DESIGN Prospective observational study. Standard case report forms for suspected sepsis, respiratory disorders, birth asphyxia and abdominal conditions were co-developed by the Neonatal Nutrition Network (https://www.lstmed.ac.uk/nnu) collaborators. Clinicians completed forms for all admissions to their NNUs. Key data were displayed using heatmaps. SETTING Five NNUs in Nigeria and two in Kenya comprising the Neonatal Nutrition Network. PARTICIPANTS 2851 neonates, which included all neonates admitted to the seven NNUs over a 6-month period. RESULTS 1230 (43.1%) neonates had suspected sepsis, 874 (30.6%) respiratory conditions, 587 (20.6%) birth asphyxia and 71 (2.5%) abdominal conditions. For all conditions and across all NNUs, clinical criteria were used consistently with sparse use of laboratory and radiological criteria. CONCLUSION Our findings highlight the reliance on clinical criteria and extremely limited use of diagnostic technologies for common conditions in NNUs in sub-Saharan Africa. This has implications for the management of neonatal conditions which often have overlapping clinical features. Strategies for implementation of diagnostic pathways and investment in affordable and sustainable diagnostics are needed to improve care for these vulnerable infants.

Abstract
BACKGROUND A negative impact of premature birth on health in adulthood is well established. However, it is not clear whether healthy adults who were born prematurely but have similar physical activity levels compared to adults born at term have a reduced maximal aerobic exercise capacity (maximum oxygen consumption [VO2max]). OBJECTIVE We aimed to determine the effect of premature birth on aerobic exercise capacity and lung function in otherwise healthy, physically active individuals. METHODS A broad literature search was conducted in the PubMed database. Search terms included 'preterm/premature birth' and 'aerobic exercise capacity'. Maximal oxygen consumption (mL/kg/min) was the main variable required for inclusion, and amongst those investigations forced expiratory volume in 1 s (FEV1, % predicted) was evaluated as a secondary parameter. For the systematic review, 29 eligible articles were identified. Importantly, for the meta-analysis, only studies which reported similar activity levels between healthy controls and the preterm group/s were included, resulting in 11 articles for the VO2max analysis (total n = 688, n = 333 preterm and n = 355 controls) and six articles for the FEV1 analysis (total n = 296, n = 147 preterm and n = 149 controls). Data were analysed using Review Manager ( Review Manager. RevMan version 5.4 software. The Cochrane Collaboration; 2020.). RESULTS The systematic review highlighted the broad biological impact of premature birth. While the current literature tends to suggest that there may be a negative impact of premature birth on both VO2max and FEV1, several studies did not control for the potential influence of differing physical activity levels between study groups, thus justifying a focused meta-analysis of selected studies. Our meta-analysis strongly suggests that prematurely born humans who are otherwise healthy do have a reduced VO2max (mean difference: - 4.40 [95% confidence interval - 6.02, - 2.78] mL/kg/min, p < 0.00001, test for overall effect: Z = 5.32) and FEV1 (mean difference - 9.22 [95% confidence interval - 13.54, - 4.89] % predicted, p < 0.0001, test for overall effect: Z = 4.18) independent of physical activity levels. CONCLUSIONS Whilst the current literature contains mixed findings on the effects of premature birth on VO2max and FEV1, our focused meta-analysis suggests that even when physical activity levels are similar, there is a clear reduction in VO2max and FEV1 in adults born prematurely. Therefore, future studies should carefully investigate the underlying determinants of the reduced VO2max and FEV1 in humans born preterm, and develop strategies to improve their maximal aerobic capacity and lung function beyond physical activity interventions.

Trends in the use of non-invasive respiratory support for term infants in tertiary neonatal units in Australia and New Zealand. Arch Dis Child Fetal Neonatal Ed 2022; 107:572-576. [PMID: 35410897 DOI: 10.1136/archdischild-2021-323581] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 03/17/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVE To determine whether the use of non-invasive respiratory support, such as continuous positive airway pressure and nasal high flow, to treat term infants in Australian and New Zealand tertiary neonatal intensive care units (NICUs) has changed over time, and if so, whether there are parallel changes in short-term respiratory morbidities. DESIGN Retrospective database review of patient-level data from the Australian and New Zealand Neonatal Network (ANZNN) from 2010 to 2018. Denominator data on the number of term inborn livebirths in each facility was only available as annual totals. PATIENTS AND SETTING Term, inborn infants cared for in NICUs within the ANZNN. MAIN OUTCOME MEASURES The primary outcome was the annual change in hospital-specific rates of non-invasive respiratory support per 1000 inborn livebirths, expressed as a percentage change. Secondary outcomes were the change in rates of mechanical ventilation, pneumothorax requiring drainage, exogenous surfactant treatment and death before hospital discharge. RESULTS A total of 14 656 term infants from 21 NICUs were included from 2010 to 2018, of whom 12 719 received non-invasive respiratory support. Non-invasive respiratory support use increased on average by 8.7% per year (95% CI: 7.9% to 9.4% per year); the number of term infants receiving non-invasive respiratory support almost doubled from 980 in 2010 (10.8/1000 livebirths) to 1913 in 2018 (20.8/1000). There was no change over time in rate of mechanical ventilation or death. The rate of pneumothorax requiring drainage increased over time, as did surfactant treatment. CONCLUSIONS Non-invasive respiratory support use to treat term infants cared for in NICUs within the ANZNN is increasing over time. Clinicians should be diligent in selecting infants most likely to benefit from treatment with non-invasive respiratory support in this relatively low-risk population of term newborn infants. Analysis of patient-level data by individual NICUs is recommended to control for potential confounding due to changes in population over time.

Abstract
OBJECTIVES to analyze the risks of deaths in the first 24 hours of life and their preventable causes. METHODS cross-sectional study carried out in Pernambuco, Northeast of Brazil, between 2000-2019, with mortality and live birth data. The avoidability was analyzed through the Brazilian List of Avoidable Causes of Deaths due to Interventions of the Unified Health System. For the statistical analyses, Pearson's chi-squared test and relative and attributable risks were used. RESULTS 13,601 deaths were registered, of which 10,497 (77.19%) were from preventable causes. Of the total, 5,513 (40.53%) were reducible through adequate care for women during pregnancy. The lower the gestational age, birth weight and education level, the higher the relative and attributable risk of death in the first 24 hours of life. CONCLUSIONS most of the deaths were considered avoidable and with high relative and attributable risks. These early deaths suggest care failures and the need to reinforce prevention and treatment measures.

Abstract
Evidence supporting clinical recommendations or approval for less invasive surfactant administration (LISA) has primarily examined heterogeneous or small-volume (e.g., 1.25-2.5 mL/kg) animal-derived surfactant regimens. To address the evidence gap for larger-volume (e.g., 4-5 mL/kg) animal-derived surfactants, the aim of this review was to evaluate and summarize LISA literature for widely used larger-volume beractant. Surfactant treatment and the LISA technique were initially summarized. The available literature on beractant with LISA was thoroughly assessed and reviewed, including a recent systematic analysis, studies from regions where access or preferences may influence reliance on larger-volume surfactants, and investigations of short- and long-term outcomes. The available literature indicated improved short-term outcomes, including less need for mechanical ventilation, death, or bronchopulmonary dysplasia, and no negative long-term developmental outcomes when beractant was administered via LISA compared with older, more invasive techniques. The rates of short-term outcomes were similar to those previously observed in examinations of LISA with small-volume surfactants, including in populations reflecting very preterm infants. As uptake of LISA is expected to increase, future research directions for larger-volume surfactants include cost-effectiveness evaluations and robust examinations of repeat dosing and surfactant reflux to further inform clinical practice. This review provides a detailed assessment of the literature describing surfactant and LISA, with a focus on studies of beractant. Collectively, the available evidence supports the use of beractant with LISA based both on short-term and long-term outcomes relative to more invasive techniques and comparability of outcomes with small-volume surfactants and may be valuable in guiding clinical decision-making.

Abstract
Most artificial intelligence (AI) studies have focused primarily on adult imaging, with less attention to the unique aspects of pediatric imaging. The objectives of this study were to (1) identify all publicly available pediatric datasets and determine their potential utility and limitations for pediatric AI studies and (2) systematically review the literature to assess the current state of AI in pediatric chest radiograph interpretation. We searched PubMed, Web of Science and Embase to retrieve all studies from 1990 to 2021 that assessed AI for pediatric chest radiograph interpretation and abstracted the datasets used to train and test AI algorithms, approaches and performance metrics. Of 29 publicly available chest radiograph datasets, 2 datasets included solely pediatric chest radiographs, and 7 datasets included pediatric and adult patients. We identified 55 articles that implemented an AI model to interpret pediatric chest radiographs or pediatric and adult chest radiographs. Classification of chest radiographs as pneumonia was the most common application of AI, evaluated in 65% of the studies. Although many studies report high diagnostic accuracy, most algorithms were not validated on external datasets. Most AI studies for pediatric chest radiograph interpretation have focused on a limited number of diseases, and progress is hindered by a lack of large-scale pediatric chest radiograph datasets.

Abstract
Introduction Despite the relatively higher neonatal morbidity and mortality in developing countries, there are limited data on the detailed analysis of the burden in Nigeria. With a database of over 14,000 admissions, this study presents a compelling picture of the current trends disaggregated by their gestational age groups. It provides unique opportunities for better-targeted interventions for further reducing newborn mortality in line with SDG 3, Target 3.2. Methods This prospective observational study involved newborn babies admitted to the Neonatal Intensive Care Unit of the University of Ilorin Teaching Hospital, Kwara State, Nigeria, between January 2007 and December 2018. The outcome was the neonatal mortality rates. The exposure variables included birth weight, gestational age (preterm versus term), and clinical diagnosis. Frequencies were generated on tables and charts, and the trends or associations were determined. Results Of the 14,760 neonates admitted, 9,030 (61.2%) were term babies, 4,847 (32.8%) were preterm babies, and in 792 (5%) of the admissions, the gestational ages could not be determined. Males constituted a higher proportion with 55.9%, and the total number of deaths in the study period was 14.7%. The mortality ratio was highest among babies with a birth weight of less than 1,000 g (38.0%) and gestational age of less than 28 weeks (65.5%). The trend analysis showed that the mortality rate decreased from 17.8 to 13% over the 12 years, p-value < 0.0001. For term babies, mortality decreased by 45%, from 15.7% in 2007 to 8.7% in 2018, while the decline in mortality for preterm babies was 28.4%, from 25.7% in 2007 to 18.4% in 2018. For both categories, p-values were < 0.001. Regarding morbidity in term babies, asphyxia occurred in (1:3), jaundice (1:5), sepsis (1:6), and respiratory disorders (1:6) of admissions. For mortality, asphyxia occurred in (1:2), sepsis (1:5), jaundice (1:8), and respiratory disorders (1:10) of deaths. The leading causes of morbidity among preterm babies were asphyxia (1:4), sepsis (1:5), respiratory disorders (1:9), and jaundice (1.10). For mortality, their contributions were asphyxia (≈1:2); sepsis (1:5); respiratory disorders (1:9), and jaundice (1:10). Conclusion There was a marked improvement in neonatal mortality trends. However, severe perinatal asphyxia, sepsis, hyperbilirubinemia, and respiratory disorders were the leading conditions contributing to 75% of the morbidities and mortalities. Measures to further accelerate the reduction in neonatal morbidity and mortality are discussed.

Abstract
Background Respiratory infections are the most frequent health problem in childhood leading to morbidity and socioeconomic burden. Studying symptoms of respiratory infections in home based settings requires dedicated prospective cohort studies using diaries. However, no information is available on which birth cohort studies using symptom diary data. A review of birth cohort studies with available symptom diary data, follow-up data, and bio samples is needed to support research collaborations and create potential synergies. Methods We conducted a scoping review of birth cohort studies using diaries for the collection of respiratory symptoms. The scoping review was conducted in accordance with the PRISMA Extension. We searched the electronic databases PubMed, Embase, Web of science and CINAHL (last search November 2020) resulting in 5872 records (based on title and abstract screening) eligible for further screening. Results We examined 735 records as full text articles and finally included 57 according to predefined inclusion criteria. We identified 22 birth cohort studies that collect(ed) data on respiratory symptoms using a symptom diary starting at birth. Numbers of participants ranged from 129 to 8677. Eight studies collected symptom diary information only for the first year of life, nine for the first two years or less and six between three and six years. Most of the cohorts collected biosamples (n = 18) and information on environmental exposures (n = 19). Conclusion Information on respiratory symptoms with daily resolution was collected in several birth cohorts, often including related biosamples, and these data and samples can be used to study full spectrum of infections, particularly including those which did not require medical treatment.

RESUMO Objetivos: analisar os riscos de mortes nas primeiras 24 horas de vida e suas causas evitáveis. Métodos: estudo transversal realizado em Pernambuco, Nordeste do Brasil, entre 2000-2019, com dados de mortalidade e nascidos vivos. Analisou-se a evitabilidade pela Lista Brasileira de Causas de Mortes Evitáveis por Intervenções do Sistema Único de Saúde. Para as análises estatísticas, utilizou-se o teste de Qui-quadrado de Pearson e os riscos relativo e atribuível. Resultados: registraram-se 13.601 óbitos, sendo 10.497 (77,19%) por causas evitáveis. Do total, 5.513 (40,53%) eram reduzíveis por adequada atenção à mulher na gestação. Quanto menor a idade gestacional, o peso ao nascer e a escolaridade, maior o risco relativo e atribuível ao óbito nas primeiras 24 horas de vida. Conclusões: a maior parte dos óbitos foram considerados evitáveis e com elevados riscos relativo e atribuível. Esses óbitos precoces sugerem falhas assistenciais e a necessidade de reforçar as medidas de prevenção e tratamento.

Abstract
The inhaled route for drug administration in neonates offers several advantages over the systemic routes, since it delivers medications directly to the diseased organ, enabling higher doses locally with less systemic toxicity. Respiratory drugs can be administered in both ventilated and non-ventilated term and preterm infants. This review was carried out using selected literature, with a focus on the most used inhaled pharmacological agents in neonatal care, summarizing, with levels of evidence (LoE), their indications, doses, administration schedules, and main adverse effects. Information is given on several inhaled drugs, namely albuterol, budesonide, ipratropium bromide, sodium cromoglycate, racemic epinephrine, nitric oxide, treprostinil, iloprost, epoprostenol, colistin, rhDNase, hypertonic saline, and calfactant. A summary of the main and most recent published studies on each of these inhaled pharmacological agents is also presented.

Abstract
Background Respiratory disorders, including apnoea, are common in preterm infants due to their immature respiratory control compared with term-born infants. However, our inability to accurately measure respiratory rate in hospitalised infants results in unreported episodes of apnoea and an incomplete picture of respiratory activity. Methods We develop, validate and use a novel algorithm to identify interbreath intervals (IBIs) and apnoeas in preterm infants. In 42 preterm infants (1600 hours of recordings), we assess IBIs from the chest electrical impedance pneumograph using an adaptive amplitude threshold for the detection of breaths. The algorithm is refined by comparing its accuracy with clinically observed breaths and pauses in breathing. We develop an automated classifier to differentiate periods of true apnoea from artefactually low amplitude signal. We assess the performance of this algorithm in the detection of morphine-induced respiratory depression. Finally, we use the algorithm to investigate whether retinopathy of prematurity (ROP) screening alters the IBI distribution. Results Individual breaths were detected with a false-positive rate of 13% and a false-negative rate of 12%. The classifier identified true apnoeas with an accuracy of 93%. As expected, morphine caused a significant shift in the IBI distribution towards longer IBIs. Following ROP screening, there was a significant increase in pauses in breathing that lasted more than 10 s (t-statistic=1.82, p=0.023). This was not reflected by changes in the monitor-derived respiratory rate and no episodes of apnoea were recorded in the medical records. Conclusions We show that our algorithm offers an improved method for the identification of IBIs and apnoeas in preterm infants. Following ROP screening, increased respiratory instability can occur even in the absence of clinically significant apnoeas. Accurate assessment of infant respiratory activity is essential to inform clinical practice.

Abstract
OBJECTIVE Characterize the use, efficacy, and safety of poractant alfa and calfactant surfactants compared to beractant in preterm infants receiving late surfactant. STUDY DESIGN We included infants <37 weeks gestational age (GA) discharged from Pediatrix Medical Group-managed neonatal intensive care units (1997-2017). Efficacy and safety outcomes of interest were analyzed. RESULTS Of 184,770 infants administered surfactant at any time, 7846 (4.23%) received late surfactant at a median (25th, 75th percentile) PNA of 8 days (3, 22); specifically, 2976 received poractant alfa (38%), 2890 beractant (37%), and 1936 calfactant (25%). We identified no significant differences in composite efficacy or safety outcomes between surfactants in the primary analysis, but 33-36 week GA infants administered poractant alfa had significantly greater odds of developing a safety event. CONCLUSIONS Compared to beractant, there is no evidence of overall superior efficacy or safety of poractant alfa.

CHILDREN-BASEL 2021; 8:children8100917. [PMID: 34682182 PMCID: PMC8534519 DOI: 10.3390/children8100917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 10/01/2021] [Accepted: 10/13/2021] [Indexed: 11/16/2022]
Abstract
Background: The present manuscript aims to be a narrative review evaluating the association between inflammation in chorioamnionitis and damage on respiratory centers, peripheral airways, and lungs, explaining the pathways responsible for apnea in preterm babies born by delivery after chorioamnionitis. Methods: A combination of keywords and MESH words was used, including: "inflammation", "chorioamnionitis", "brainstem", "cytokines storm", "preterm birth", "neonatal apnea", and "apnea physiopathology". All identified papers were screened for title and abstracts by the two authors to verify whether they met the proper criteria to write the topic. Results: Chorioamnionitis is usually associated with Fetal Inflammatory Response Syndrome (FIRS), resulting in injury of brain and lungs. Literature data have shown that infections causing chorioamnionitis are mostly associated with inflammation and consequent hypoxia-mediated brain injury. Moreover, inflammation and infection induce apneic episodes in neonates, as well as in animal samples. Chorioamnionitis-induced inflammation favors the systemic secretion of pro-inflammatory cytokines that are involved in abnormal development of the respiratory centers in the brainstem and in alterations of peripheral airways and lungs. Conclusions: Preterm birth shows a suboptimal development of the brainstem and abnormalities and altered development of peripheral airways and lungs. These alterations are responsible for reduced respiratory control and apnea. To date, mostly animal studies have been published. Therefore, more clinical studies on the role of chorioamninitis-induced inflammation on prematurity and neonatal apnea are necessary.

Abstract
Clinically, intrauterine hypoxia is the foremost cause of perinatal morbidity and developmental plasticity in the fetus and newborn infant. Under hypoxia, deviations occur in the lung cell epigenome. Epigenetic mechanisms (e.g., DNA methylation, histone modification, and miRNA expression) control phenotypic programming and are associated with physiological responses and the risk of developmental disorders, such as bronchopulmonary dysplasia. This developmental disorder is the most frequent chronic pulmonary complication in preterm labor. The pathogenesis of this disease involves many factors, including aberrant oxygen conditions and mechanical ventilation-mediated lung injury, infection/inflammation, and epigenetic/genetic risk factors. This review is focused on various aspects related to intrauterine hypoxia and epigenetic programming in lung development and disease, summarizes our current knowledge of hypoxia-induced epigenetic programming and discusses potential therapeutic interventions for lung disease.

Adenosine A2a receptors modulate TrkB receptor-dependent respiratory plasticity in neonatal rats. Respir Physiol Neurobiol 2021; 294:103743.

Abstract
Neuroplasticity is a fundamental property of the respiratory control system, enabling critical adaptations in breathing to meet the challenges, but little is known whether neonates express neuroplasticity similar to adults. We tested the hypothesis that, similar to adults, tyrosine receptor kinase B (TrkB) or adenosine A2a receptor activation in neonates are independently sufficient to elicit respiratory motor facilitation, and that co-induction of TrkB and A2a receptor-dependent plasticity undermines respiratory motor facilitation. TrkB receptor activation with 7,8-dihydroxyflavone (DHF) in neonatal brainstem-spinal cord preparations induced a long-lasting increase in respiratory motor output in 55 % of preparations, whereas adenosine A2a receptor activation with CGS21680 only sporadically induced respiratory motor plasticity. CGS21680 and DHF co-application prevented DHF-dependent respiratory motor facilitation, whereas co-application of MSX-3 (adenosine A2a receptor antagonist) and DHF more rapidly induced respiratory motor plasticity. Collectively, these data suggest that mechanisms underlying respiratory neuroplasticity may be only partially operational in early neonatal life, and that adenosine A2a receptor activation undermines TrkB-induced respiratory plasticity.

Abstract
BACKGROUND Nasal trauma due to nasal CPAP (nCPAP) use is a commonly reported complication in infants under 1500 g of birth weight and 32 weeks of gestation. With the rise of nCPAP as the gold standard for non-invasive respiratory support, preventive measures should be considered. OBJECTIVE To assess the prevalence and risk factors of nasal injury in very low birth weight (VLBW) preterm infants with nCPAP. METHODS We retrospectively analyzed neonates hospitalized between 2012 and 2017, with less than 1500 g and 32 weeks of gestational age who received more than 12 hours of nCPAP. Demographic, antenatal and clinical data, along with information regarding respiratory support and nCPAP complications, were collected. We used Fischer's classification to grade nasal trauma. RESULTS A total of 135 infants were evaluated. Mean gestational age was 28 weeks (SD 2) and mean birth weight 1072 g (SD 239). Nasal trauma was reported in 65% of patients and it was of stage I, II and III in 49%, 16% and 1% of patients, respectively. The multivariate logistic regression revealed that the risk of trauma was greater in neonates with a longer duration of nCPAP ventilation (OR = 1.098, 95% CI: 1.055-1.142; p < 0.001) and in patients submitted to oxygen therapy (OR = 3.174, 95% CI: 1.014-9.929, p = 0.004). The median of days after nCPAP administration until the onset of an identifiable lesion was 4. CONCLUSION Nasal trauma is a frequent complication in VLBW preterm infants using nCPAP for long periods. Preventive measures in patients who are at greater risk of skin breakdown are of major clinical importance for a better outcome.

Abstract
The neonatal period - the first 4 weeks of life - is the most critical time for a child's survival. Breathing rate is a vital indicator of the health condition and requires continuous monitoring in case of sickness or preterm birth. Breathing movements can be counted by contact and non-contact methods. In the case of newborn infants, the non-contact breathing rate monitoring need is high, as a contact-based approach may interfere while providing care and is subject to interference by non-breathing movements. This review article delivers a factual summary, and describes the methods and processing involved in non-contact based breathing rate monitoring. The article also provides the advantages, limitations, and clinical applications of these methods. Additionally, signal processing, feasibility, and future direction of different non-contact neonatal breathing rate monitoring are discussed.

Abstract
BACKGROUND The proportion of deaths attributed to various causes has not been quantified among infants with birth defects. We sought to describe the causes of neonatal and postneonatal death among infants in the Texas Birth Defects Registry. METHODS We calculated frequencies and percentages for both underlying causes and all causes (underlying or contributing) of neonatal (0-27 days) and postneonatal (28-364 days) death listed on death certificates among infants born alive with birth defects and delivered in Texas during 1999-2013 (n = 8,389 deaths). Analyses were repeated separately for infants with isolated, multiple, and syndromic defects. RESULTS After birth defects, the most frequently listed causes of neonatal death were preterm/low birth weight (10%), circulatory system diseases (8%), and sepsis (5%). The leading postneonatal causes of death beyond birth defects were circulatory system diseases (32%), sepsis (11%), and renal failure (7%). CONCLUSIONS Improved understanding of the causes of mortality among infants with birth defects may help identify priorities for postnatal care. Our results suggest that potentially modifiable causes of death (e.g., circulatory system diseases, sepsis) contribute substantially to mortality in this population. Prioritizing continued improvements in prevention, diagnosis, and management of preventable conditions may reduce mortality among infants born with birth defects.

Abstract
OBJECTIVES A major challenge for hospitals and clinicians is the early identification of neonates at risk of developing adverse conditions. We develop a model based on routinely collected administrative data, which accurately predicts two common disorders among early term and preterm (<39 weeks) neonates prior to discharge. STUDY DESIGN The data included all inpatient live births born prior to 39 weeks (n = 154,755) occurring in the Australian state of Queensland between January 2009 and December 2015. Predictor variables included all maternal data captured in administrative records from the beginning of gestation up to, and including, the delivery, as well as neonatal data recorded at the delivery. Gradient boosted trees were used to predict neonatal respiratory distress syndrome and hypoglycaemia prior to discharge, with model performance benchmarked against a logistic regression models. RESULTS The gradient boosted trees model achieved very high discrimination for respiratory distress syndrome [AUC = 0.923, 95% CI (0.917, 0.928)] and good discrimination for hypoglycaemia [AUC = 0.832, 95% CI (0.827, 0.837)] in the validation data, as well as outperforming the logistic regression models. CONCLUSION Our study suggests that routinely collected health data have the potential to play an important role in assisting clinicians to identify neonates at risk of developing selected disorders shortly after birth. Despite achieving high levels of discrimination, many issues remain before such models can be implemented in practice, which we discuss in relation to our findings.

Abstract
This study demonstrates that rule-of-thumb health treatment decision-making exists when assigning medical care to macrosomic newborns with an extremely high birth weight and estimates the short-run health return to neonatal care for infants at the high end of the birth weight distribution. Using a regression discontinuity design, we find that infants born with a birth weight above 5000 grams have a 2 percentage-point higher probability of admission to a neonatal intensive care unit and a 1 percentage-point higher probability of antibiotics receipt, compared to infants with a birth weight below 5000 grams. We also find that being born above the 5000-gram cutoff has a mortality-reducing effect: infants with a birth weight larger than 5000 grams face a 0.15 percentage-point lower risk of mortality in the first week and a 0.20 percentage-point lower risk of mortality in the first month, compared to their counterparts with a birth weight below 5000 grams. We do not find any evidence of changes in health treatments and mortality at macrosomic cutoffs lower than 5000 grams, which is consistent with the idea that such treatment decisions are guided by the higher expected morbidity and mortality risk associated with infants weighing more than 5000 grams.

Abstract
OBJECTIVE Preterm prelabor rupture of membranes (PPROM) precedes 30%-40% of all preterm births. Early preterm delivery (<34 gestation weeks) is a well-established risk factor for short- and long-term respiratory morbidity in the offspring. We aimed to ascertain whether the presence of PPROM, before early preterm delivery, independently impacts long-term respiratory hospitalizations in the offspring. STUDY DESIGN A population-based retrospective cohort analysis was performed including all singleton early preterm deliveries. Exposure was defined as the presence of PPROM. Hospitalizations of the offspring up to the age of 18 years involving respiratory-related morbidity were evaluated. A Kaplan-Meier survival curve and multivariable Cox regression model were used to assess the association. RESULTS During the study period, 3309 early preterm deliveries met the inclusion criteria. In 22.4% of cases (n = 742), PPROM was documented. Rates of respiratory-related hospitalizations of the offspring up to the age of 18 years were significantly higher in the exposed group (12.5% vs 9.4% in the unexposed group, P = .023). The survival curve demonstrated significantly higher cumulative incidence of respiratory hospitalizations in the exposed group (logrank P = .018). In the Cox regression model controlled for gestational age, and other clinically relevant confounders - PPROM before early preterm deliveries was independently associated with an increased risk for long-term childhood respiratory-related hospitalizations in the offspring (adjusted hazard ratio 1.40, 95% confidence interval, 1.05-1.87, P = .021). CONCLUSION Fetal exposure to PPROM before early preterm delivery was associated with an increased risk for long-term respiratory hospitalizations in the offspring.

Abstract
Proper organ development depends on coordinated communication between multiple cell types. Retinoic acid (RA) is an autocrine and paracrine signaling molecule essential for the development of most organs, including the lung. Despite extensive work detailing effects of RA deficiency in early lung morphogenesis, little is known about how RA regulates late gestational lung maturation. Here, we investigate the role of the RA catabolizing protein Cyp26b1 in the lung. Cyp26b1 is highly enriched in lung endothelial cells (ECs) throughout development. We find that loss of Cyp26b1 leads to reduction of alveolar type 1 cells, failure of alveolar inflation and early postnatal lethality in mouse. Furthermore, we observe expansion of distal epithelial progenitors, but no appreciable changes in proximal airways, ECs or stromal populations. Exogenous administration of RA during late gestation partially mimics these defects; however, transcriptional analyses comparing Cyp26b1-/- with RA-treated lungs reveal overlapping, but distinct, responses. These data suggest that defects observed in Cyp26b1-/- lungs are caused by both RA-dependent and RA-independent mechanisms. This work reports crucial cellular crosstalk during lung development involving Cyp26b1-expressing endothelium and identifies a novel RA modulator in lung development.

Abstract
Introduction: Respiratory distress syndrome (RDS) is a respiratory disorder of neonates that manifests itself within few hours after delivery. It is one of the most common causes of admission to neonatal intensive care unit (NICU) and respiratory failure in neonates. Aim: The aim of this study was to determine the incidence, risk factors, and the short-term outcomes of RDS in term infants born in an academic tertiary care center at King Abdul-Aziz University Hospital (KAUH), Jeddah, Saudi Arabia. Methods: Data of all infants admitted to the NICU at the academic center between January 1st 2016 and December 31st 2016 were retrospectively collected. Cases were all term infants who were admitted to NICU with the diagnosis of RDS during the study period. Controls were term infants and 1:1 matched for the date of birth (one or two days from the date of birth of the case) and received routine newborn care. Results: Fifty-nine term infants (59/3601, 1.64%) were admitted to the NICU with RDS and 59 control infants were matched during the study period. Infants with RDS were significantly of lower birth weight and had lower Apgar scores at one and five minutes. Although there was a higher number of cesarean section and PROM in the RDS group, but that didn’t reach statistical significance. Three infants (5.1%) died in the RDS group. Conclusion: Respiratory distress in term infants is still a significant cause of admission to NICU and a predisposing factor for neonatal mortality and morbidity. Preventative and anticipatory measures should be further explored to decrease the burden of this disease.

Tian T, Wang L, Ye R, Liu J, Ren A. Maternal hypertension, preeclampsia, and risk of neonatal respiratory disorders in a large-prospective cohort study. Pregnancy Hypertens 2020; 19:131-137. [PMID: 31982835 DOI: 10.1016/j.preghy.2020.01.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 01/07/2020] [Accepted: 01/10/2020] [Indexed: 10/25/2022]
Abstract
BACKGROUND Possible impact of maternal hypertension and preeclampsia on neonatal respiratory disorders was unknown. We investigated the association of maternal hypertension and preeclampsia with neonatal respiratory disorders in preterm and full-term newborns. METHOD In this study, we used a large Chinese population-based study which includes 185,687 singleton livebirths with gestational weeks between 28 and 42 weeks. The "exposure" was maternal hypertension and preeclampsia. The outcome was neonatal respiratory disorders including neonatal respiratory distress syndrome (NRDS), pneumonia and low Apgar scores. Logistic regression was used to examine the association between the maternal hypertensive disorders and the risk for neonatal respiratory disorders. We further evaluated the association in preterm and full-term infants. RESULTS As a result, the incidence of neonatal RDS, pneumonia, and low Apgar score in hypertensive group was higher than that in normotensive group. Preeclampsia was associated with RDS [(adjusted relative risk (aRR): 1.85, 95% confidence interval (CI): 1.22-3.05)]. Both maternal hypertension and preeclampsia increased risks for neonatal pneumonia (aRR: 1.79, 95%CI: 1.48-2.17; aRR: 1.81, 95%CI: 1.36-2.40, respectively), for low Apgar score at 1 min (aRR: 1.20, 95%CI: 1.13-1.27; aRR: 1.53, 95%CI: 1.41-1.67, respectively), and for low Apgar score at 5 min (aRR: 1.30, 95%CI: 1.17-1.45; aRR: 1.70, 95%CI: 1.46-1.99, respectively). The risk for neonatal respiratory disorders increased with severity of maternal hypertension. The observed associations were present in both full-term and preterm birth. CONCLUSION Maternal hypertension and preeclampsia are risk factors for neonatal respiratory disorders in full-term and preterm newborns.

Beractant and poractant alfa in premature neonates with respiratory distress syndrome: a systematic review of real-world evidence studies and randomized controlled trials. J Perinatol 2020; 40:1121-1134.

Abstract
Findings from previous meta-analyses of randomized clinical trials (RCTs) in premature infants with respiratory distress syndrome (RDS) varied as to whether clinical outcomes differed by type of animal-derived pulmonary surfactant; real-world evidence (RWE) was excluded. We extracted study characteristics and outcomes from full-text articles from a systematic search for studies that compared beractant with poractant alfa for RDS in preterm infants. RWE data were tabulated; RCT data were subjected to meta-analyses. Designs, patient characteristics, and follow-up durations varied widely among studies (4 RWE, 15 RCT). RWE studies with adjusted odds ratios (ORs) found no statistically significant between-treatment differences in outcomes. In RCT meta-analyses, no statistically significant between-treatment differences were observed for death (OR [95% confidence interval], 1.35 [0.98-1.86]), bronchopulmonary dysplasia (1.25 [0.96-1.62]), pneumothorax (1.21 [0.72-2.05]), and air leak syndrome (2.28 [0.82-6.39]). Collectively, outcomes were similar with beractant and poractant alfa in RWE studies and pooled RCTs.

Abstract
With the improvement in neonatal care in last two decades, the survival of very low birth weight (VLBW), extremely low birth weight (ELBW), fetus diagnosed with malformations, and congenital heart disease and severe birth asphyxia has increased significantly. These infants when admitted to the neonatal intensive care unit (NICU) need numerous interventions depending upon the severity of sickness and postnatal course like need of mechanical ventilation (MV) or noninvasive ventilation, surfactant administration, placement of central lines, total parenteral nutrition, and numerous medications. The duration of NICU and hospital stay of these high-risk infants varies from few days to few weeks to few months. Long stay in the hospital leads to high hospital bills and increase the cost of neonatal care substantially. The cost of NICU stay varies from 90 USD to 1250-2500 USD per day as per various studies, depending upon the level of care and sickness of the admitted infants. In developed countries, the burden of NICU cost is often taken care by the government or insurance companies but in many developing countries the parents bear the substantial cost of NICU admission of their infants. There are many interventions which when implemented in the NICU will lead to reduction of the cost and will make the NICU cost effective. In this review, we cover various interventions mostly from our own published work which have shown to reduce the NICU cost and make it more cost effective with equivalent and better neonatal outcomes, especially in developing countries like ours.

Abstract
BACKGROUND The most common neonatal tumor is neuroblastoma and adrenal gland is the most common site of involvement. 11-26% of this tumor is seen in the thorax of neonates. Due to a similar appearance of the mediastinal tumor with pneumonia, a high index of suspicion is necessary for early diagnosis of this disorder. CASE REPORT A 17-day -old female and term neonate delivered by caesarian section was reported in the study. The mother had a normal pregnancy without any reported complications. The newborn admitted to a neonatal intensive care unit (NICU) in her hometown, because of respiratory distress, stridor, and tachypnea which was started from 7 days of life and due to lack of recovery and persistent respiratory symptoms, the patient referred to our hospital. In chest X-ray, opacity in the right upper lobe of the lung was seen. In barium study, a mass like lesion in the size of 35.34 mm adjacent to upper intra-thoracic esophagus with mild mass effect was observed and in CTS a posterior mediastinal mass with severe compression on the trachea and extension to the spinal canal was reported. Due to severe obstruction on the airway, the baby underwent emergency surgery and a mediastinal mass with adhesion and involvement of the ribs and spinal cord was resected. The final diagnosis of poorly differentiated neuroblastoma was confirmed by biopsy. CONCLUSION In every neonate with persistent respiratory distress, stridor and abnormal chest X-ray, diagnosis of neonatal neuroblastoma should be considered.

Abstract
Respiratory frequency plasticity is a long-lasting increase in breathing frequency due to a perturbation. Mechanisms underlying respiratory frequency are poorly understood, and there is little evidence of frequency plasticity in neonates. This hybrid review/research article discusses available literature regarding frequency plasticity and highlights potential research opportunities. Also, we include data demonstrating a model of frequency plasticity using isolated neonatal rat brainstem-spinal cord preparations. Specifically, substance P (SubP) application induced a long-lasting (>60 min) increase in spontaneous respiratory motor burst frequency, particularly in brainstem-spinal cords with the pons attached; there were no male/female differences. SubP-induced frequency plasticity is dependent on the application pattern, such that intermittent (rather than sustained) SubP applications induce more frequency plasticity. SubP-induced frequency plasticity was blocked by a neurokinin-1 receptor antagonist. Thus, the newborn rat respiratory control system has the capacity to express frequency plasticity. Identifying mechanisms that induce frequency plasticity may lead to novel methods to safely treat breathing disorders in premature and newborn infants.

Abstract
The respiratory system undergoes a diversity of structural, biochemical, and functional changes necessary for adaptation to air breathing at birth. To identify the heterogeneity of pulmonary cell types and dynamic changes in gene expression mediating adaptation to respiration, here we perform single cell RNA analyses of mouse lung on postnatal day 1. Using an iterative cell type identification strategy we unbiasedly identify the heterogeneity of murine pulmonary cell types. We identify distinct populations of epithelial, endothelial, mesenchymal, and immune cells, each containing distinct subpopulations. Furthermore we compare temporal changes in RNA expression patterns before and after birth to identify signaling pathways selectively activated in specific pulmonary cell types, including activation of cell stress and the unfolded protein response during perinatal adaptation of the lung. The present data provide a single cell view of the adaptation to air breathing after birth. The respiratory system is transformed in terms of functional change at birth to adapt to breathing air. Here, the authors examine the molecular changes behind the first breath in the mouse by Drop-seq based RNA sequencing, identifying activation of the unfolded protein response as a perinatal adaptation of the lung.

Abstract
PURPOSE Bubble continuous positive airway pressure (bCPAP), a noninvasive respiratory support modality used to manage newborns with respiratory distress, provides continuous pressure that helps prevent derecruitment of alveoli, increasing the lungs' functional residual capacity, and thus decreasing the work of breathing. bCPAP can be used to manage various respiratory conditions in the newborn. In this prospective study, we describe our experience using bCPAP therapy as the primary respiratory support in a level III neonatal unit in Amman, Jordan. In addition to reporting therapeutic indications, durations, and side effects, we aimed to identify areas requiring improvement in bCPAP therapy in our population. PATIENTS AND METHODS This prospective observational study investigated the usage of bCPAP in the management of respiratory distress in newborns admitted to a Jordan University Hospital in Amman. The newborns were followed until discharge. The patients' demographic and clinical data were recorded. RESULTS A total of 143 babies (mean gestational age, 36±2.7 weeks; mean birth weight, 2,770±1,800 g) were included. All received bCPAP as the primary respiratory support. The most common underlying cause of respiratory distress was transient tachypnea of the newborn (42%), followed by prolonged respiratory transition (34%). The therapy success rate was 93.7%; only nine infants failed bCPAP. The most common side effect was physical facial injury. CONCLUSION The use of neonatal bCPAP therapy is well established in Jordan University Hospital. The area of potential improvement was the low rate of bCPAP use as a primary respiratory support in extremely premature infants.
