Abstract
BACKGROUND Pressure ulcers are the most common complications in bedridden patients or those with spinal cord injuries. Marjolin's ulcer refers to a malignant transformation arising from burn scars or chronic nonhealing wounds-such as pressure ulcers-over many years. Squamous cell carcinoma is the major histopathologic type of Marjolin's ulcer, and the gold standard for diagnosis is tissue biopsy. Medical professionals may have difficulty distinguishing pressure ulcers from Marjolin's ulcer, especially when the latter presents with invasive infections. Thus, malignant transformations arising from pressure ulcers are frequently overlooked. Herein, we describe a case of squamous cell carcinoma arising from pressure ulcers on the left ischium, which was initially identified as a necrotizing soft tissue infection. CASE REPORT A 59-year-old paraplegic patient presented with stage 3 left ischial pressure ulcer, which involves full-thickness skin loss and extends into deep subcutaneous tissue, and arrived at our hospital with suspected sepsis. Upon physical examination, the patient presented with fever and shivering. Initial examination and imaging findings revealed the presence of necrotizing soft tissue infections. Three weeks later, rapid increase in granulation in the deep part of the ulcer was observed. Samples from multiples ulcer sites were collected for tissue biopsy. Finally, histological examination revealed well-differentiated squamous cell carcinoma. The patient received radiation therapy and chemotherapy and died 11 months after the diagnosis. CONCLUSION Malignant transformations arising from pressure ulcers may closely resemble pressure ulcer infections. In these cases, tissue biopsies should be performed during primary care for the infection to exclude malignant transformations.

Abstract
INTRODUCTION Despite changes in prenatal diagnostic methods and perceptions regarding the prognosis of and treatment options for patients with trisomy 18 syndrome, data on the secular changes in patient survival are limited. This study aimed to investigate the survival pattern for such patients. METHODS To investigate the general patient survival patterns, we used data from the vital statistics database of deaths in Japan from 1975 to 2016. We described demographic factors, such as sex, gestational age at delivery, and surgical history, for patients whose primary cause of death was trisomy 18 syndrome. RESULTS The proportions of deaths within 24 h of birth (4.0% in 1975-1980 to 21.9% in 2011-2016) and at age ≥1 year (8.9% in 1975-1980 to 17.7% in 2011-2016) increased. The median survival time was higher for females, infants born after 37 weeks of gestation, and those who received surgical intervention. The median survival time tripled among patients who received surgical intervention (61.5 days in 1995-2005 to 182.5 days in 2006-2016), and the proportion of such patients increased (from 3.8% in 1995 to 24.1% of the entire affected population in 2016). DISCUSSION/CONCLUSION In Japan, the median survival time of infants with trisomy 18 increased over time, and the proportion of death within 24 h and at ≥1 year increased. Greater acknowledgement of the possible benefits of surgical intervention likely led to the increased provision of interventions and contributed to the increased survival time.

Neonatal outcomes of extremely preterm twins by sex pairing: an international cohort study. Arch Dis Child Fetal Neonatal Ed 2021; 106:17-24. [PMID: 32451356 DOI: 10.1136/archdischild-2020-318832] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 04/09/2020] [Accepted: 04/23/2020] [Indexed: 11/04/2022]
Abstract
OBJECTIVE Infant boys have worse outcomes than girls. In twins, the 'male disadvantage' has been reported to extend to female co-twins via a 'masculinising' effect. We studied the association between sex pairing and neonatal outcomes in extremely preterm twins. DESIGN Retrospective cohort study SETTING: Eleven countries participating in the International Network for Evaluating Outcomes of Neonates. PATIENTS Liveborn twins admitted at 23-29 weeks' gestation in 2007-2015. MAIN OUTCOME MEASURES We examined in-hospital mortality, grades 3/4 intraventricular haemorrhage or cystic periventricular leukomalacia (IVH/PVL), bronchopulmonary dysplasia (BPD), retinopathy of prematurity requiring treatment and a composite outcome (mortality or any of the outcomes above). RESULTS Among 20 924 twins, 38% were from male-male pairs, 32% were from female-female pairs and 30% were sex discordant. We had no information on chorionicity. Girls with a male co-twin had lower odds of mortality, IVH/PVL and the composite outcome than girl-girl pairs (reference group): adjusted OR (aOR) (95% CI) 0.79 (0.68 to 0.92), 0.83 (0.72 to 0.96) and 0.88 (0.79 to 0.98), respectively. Boys with a female co-twin also had lower odds of mortality: aOR 0.86 (0.74 to 0.99). Boys from male-male pairs had highest odds of BPD and composite outcome: aOR 1.38 (1.24 to 1.52) and 1.27 (1.16 to 1.39), respectively. CONCLUSIONS Sex-related disparities in outcomes exist in extremely preterm twins, with girls having lower risks than boys and opposite-sex pairs having lower risks than same-sex pairs. Our results may help clinicians in assessing risk in this large segment of extremely preterm infants.

Abstract
OBJECTIVES To evaluate the proportion of neonatal intensive care units with facilities supporting parental presence in their infants' rooms throughout the 24-hour day (ie, infant-parent rooms) in high-income countries and to analyze the association of this with outcomes of extremely preterm infants. STUDY DESIGN In this survey and linked cohort study, we analyzed unit design and facilities for parents in 10 neonatal networks of 11 countries. We compared the composite outcome of mortality or major morbidity, length of stay, and individual morbidities between neonates admitted to units with and without infant-parent rooms by linking survey responses to patient data from 2015 for neonates of less than 29 weeks of gestation. RESULTS Of 331 units, 13.3% (44/331) provided infant-parent rooms. Patient-level data were available for 4662 infants admitted to 159 units in 7 networks; 28% of the infants were cared for in units with infant-parent rooms. Neonates from units with infant-parent rooms had lower odds of mortality or major morbidity (aOR, 0.76; 95% CI, 0.64-0.89), including lower odds of sepsis and bronchopulmonary dysplasia, than those from units without infant-parent rooms. The adjusted mean length of stay was 3.4 days shorter (95%, CI -4.7 to -3.1) in the units with infant-parent rooms. CONCLUSIONS The majority of units in high-income countries lack facilities to support parents' presence in their infants' rooms 24 hours per day. The availability vs absence of infant-parent rooms was associated with lower odds of composite outcome of mortality or major morbidity and a shorter length of stay.

Hospital Care Cost and Resource Use of Early Discharge of Healthy Late Preterm and Term Singletons: A Population-based Cohort Study and Cost Analysis. J Pediatr 2020; 226:96-105.e7.

Abstract
OBJECTIVE To assess the hospital care cost and resource use associated with discharge timings after late preterm and term births. STUDY DESIGN This population-based cohort study and cost analysis included all healthy singleton late preterm (35-36 weeks gestational age) and term infants (37-41 weeks gestational age) born vaginally in hospitals in Ontario, Canada, from 2003 to 2012. Early, late, and very late discharge (<48, 48-71, and 72-95 hours after birth, respectively) were compared using generalized linear models. The primary outcome was the total hospital care cost (hospitalizations and emergency department visits) per infant within 28 days of birth. RESULTS Among 860 693 singletons (3.7% late preterm), early discharge increased significantly over 10 years for term infants (from 69% to 82%; P < .001), but not late preterm infants (from 32% to 35%; P = .75). The mean total cost within 28 days after birth was not significantly different for late preterm infants between early discharge and late discharge after adjustment. However, for term infants, the adjusted cost was higher with early discharge than late discharge (aMCD $311 [95% CI, $211-$412] per infant; $366 [95% CI, $355-$377] per mother-infant dyad). The neonatal readmission rates were higher after early than late discharge for late preterm and term infants. CONCLUSIONS Early discharge was not associated with cost savings for vaginally born healthy singleton late preterm infants, and instead was associated with a cost increase for term infants. Early discharge was associated with higher neonatal readmission rates. Individualized approach balancing the risk and benefit is appropriate to determine the discharge timings.

Abstract
This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR) for neonatal life support includes evidence from 7 systematic reviews, 3 scoping reviews, and 12 evidence updates. The Neonatal Life Support Task Force generally determined by consensus the type of evidence evaluation to perform; the topics for the evidence updates followed consultation with International Liaison Committee on Resuscitation member resuscitation councils. The 2020 CoSTRs for neonatal life support are published either as new statements or, if appropriate, reiterations of existing statements when the task force found they remained valid. Evidence review topics of particular interest include the use of suction in the presence of both clear and meconium-stained amniotic fluid, sustained inflations for initiation of positive-pressure ventilation, initial oxygen concentrations for initiation of resuscitation in both preterm and term infants, use of epinephrine (adrenaline) when ventilation and compressions fail to stabilize the newborn infant, appropriate routes of drug delivery during resuscitation, and consideration of when it is appropriate to redirect resuscitation efforts after significant efforts have failed. All sections of the Neonatal Resuscitation Algorithm are addressed, from preparation through to postresuscitation care. This document now forms the basis for ongoing evidence evaluation and reevaluation, which will be triggered as further evidence is published. Over 140 million babies are born annually worldwide (https://ourworldindata.org/grapher/births-and-deaths-projected-to-2100). If up to 5% receive positive-pressure ventilation, this evidence evaluation is relevant to more than 7 million newborn infants every year. However, in terms of early care of the newborn infant, some of the topics addressed are relevant to every single baby born.

Abstract
CONTEXT Current International Liaison Committee on Resuscitation recommendations on epinephrine administration during neonatal resuscitation were derived in 2010 from indirect evidence in animal or pediatric studies. OBJECTIVE Systematic review of human infant and relevant animal studies comparing other doses, routes, and intervals of epinephrine administration in neonatal resuscitation with (currently recommended) administration of 0.01 to 0.03 mg/kg doses given intravenously (IV) every 3 to 5 minutes. DATA SOURCES Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Database of Systematic Reviews, and trial registry databases. STUDY SELECTION Predefined criteria were used for selection. DATA EXTRACTION Risk of bias was assessed by using published tools appropriate for the study type. Certainty of evidence was assessed by using Grading of Recommendations Assessment, Development and Evaluation. RESULTS Only 2 of 4 eligible cohort studies among 593 unique retrieved records yielded data allowing comparisons. There were no differences between IV and endotracheal epinephrine for the primary outcome of death at hospital discharge (risk ratio = 1.03 [95% confidence interval 0.62 to 1.71]) or for failure to achieve return of spontaneous circulation, time to return of spontaneous circulation (1 study; 50 infants), or proportion receiving additional epinephrine (2 studies; 97 infants). There were no differences in outcomes between 2 endotracheal doses (1 study). No human infant studies were found in which authors addressed IV dose or dosing interval. LIMITATIONS The search yielded sparse human evidence of very low certainty (downgraded for serious risk of bias and imprecision). CONCLUSIONS Administration of epinephrine by endotracheal versus IV routes resulted in similar survival and other outcomes. However, in animal studies, researchers continue to suggest benefit of IV administration using currently recommended doses.

Abstract
Introduction Congenital complete atrioventricular block (CCAVB) associated with congenital chylothorax is a rare finding that has been reported in only one case in the literature. We report here the case of an infant with CCAVB complicated by congenital chylothorax. Patient Report We present the case of a male neonate with a birth weight of 2114 g. Fetal bradycardia and right pleural effusion were detected at gestational age of 22 weeks. Maternal serum levels of anti-Sjögren's-syndrome-related antigen A autoantibody were high (4840 U/mL). The neonate was delivered at gestational age of 33 weeks; a temporary external pacemaker was placed immediately after birth that resulted in an improved cardiac output. Milk-colored pleural effusion increased in volume together with the initiation of breast milk feeding. Lymphocytosis and high triglyceride levels in the pleural fluid led to the diagnosis of chylothorax. The pleural effusion resolved in response to prednisolone, octreotide, and total parenteral nutrition. Discussion The causal relationship between CCAVB and congenital chylothorax can be explained by considering the damage to the lymphatic vessels secondary to inflammation due to maternal autoantibodies and venous congestion due to bradycardia. Conclusion In any case of CCAVB associated with atypical pleural effusion, one must consider the possibility of congenital chylothorax.

J Pharm Health Care Sci 2020; 6:14.

Abstract
BACKGROUND The need for a large volume of serum sample significantly reduces the feasibility of neonatal pharmacokinetic studies in daily practice, which must often rely on scavenged or opportunistic sampling. This problem is most apparent in preterm newborns, where ethical and practical considerations prohibit the collection of large sample volumes. Most of the fluconazole analysis assays published thus far required a minimum serum sample of 50 to 100 μL for a single assay. The purpose of the present study was to develop and validate a sensitive method requiring a smaller sample volume (10 μL) to satisfy clinically relevant research requirements. METHODS Following simple protein precipitation and centrifugation, the filtrated supernatant was injected into a liquid chromatography system and separated with a C18 reverse-phase column. Fluconazole and the internal standard (IS, fluconazole-d4) were detected and quantified using tandem mass spectrometry. The method was validated with reference to the Food and Drug Administration's Guidance for Industry. Accuracy and precision were evaluated at six quality control concentration levels (ranging from 0.01 to 100 μg/mL). RESULTS Investigated calibration curves were linear in the 0.01-100 μg/mL range. Intra- and inter-day accuracy (- 7.7 to 7.4%) and precision (0.3 to 6.0%) were below 15%. The calculated limit of detection and the lower limit of quantification (LLOQ) was 0.0019 μg/mL and 0.0031 μg/mL, respectively. Fluconazole in the prepared samples was stable for at least 4 months at - 20 °C and - 80 °C. This method was applied to analyze 234 serum samples from ten neonates who received fosfluconazole, a water-soluble phosphate prodrug of fluconazole which converts to fluconazole in the body, as part of a pharmacokinetic study using daily scavenged laboratory samples. The median (range) concentration up to 72 h after fosfluconazole administration was 2.9 (0.02 to 26.8 μg/mL) μg/mL, which was within the range of the calibration curve. CONCLUSION Fluconazole was able to be detected in an extremely small volume (10 μL) of serum from neonates receiving fosfluconazole. The method presented here can be used to quantify fluconazole concentrations for pharmacokinetic studies of the neonatal population by using scavenged samples.

Abstract
AIM We surveyed care practices for critically ill very preterm infants admitted to neonatal intensive care units (NICUs) in the International Network for Evaluating Outcomes in Neonates (iNeo) to identify differences relevant to outcome comparisons. METHODS We conducted an online survey on care practices for critically ill very preterm infants and infants with severe intracranial haemorrhage (ICH). The survey was distributed in 2015 to representatives of 390 NICUs in 11 countries. Survey replies were compared with network incidence of death and severe ICH for infants born between 230/7 and 286/7 weeks of gestation from January 1, 2015, to December 31, 2015. RESULTS Most units in Israel, Japan and Tuscany, Italy, favoured withholding care when care was considered futile, whereas most units in other networks favoured redirection of care. For infants with bilateral grade 4 ICH, redirection of care was very frequently (≥90% of cases) offered in the majority of units in Australia and New Zealand and Switzerland, but rarely in other networks. Networks where redirection of care was frequently offered for severe ICH had lower rates of survivors with severe ICH. CONCLUSION We identified marked inter-network differences in care approaches that need to be considered when comparing outcomes.

Abstract
OBJECTIVES To assess associations between neonatal intensive care unit (NICU)-level patent ductus arteriosus (PDA) treatment rates (pharmacologic or surgical) and neonatal outcomes. STUDY DESIGN This cohort study included infants born at 24-28 weeks of gestation and birth weight <1500 g in 2007-2015 in NICUs caring for ≥100 eligible infants in 6 countries. The ratio of observed/expected (O/E) PDA treatment rates was derived for each NICU by estimating the expected rate using a logistic regression model adjusted for potential confounders and network. The primary composite outcome was death or severe neurologic injury (grades III-IV intraventricular hemorrhage or periventricular leukomalacia). The associations between the NICU-level O/E PDA treatment ratio and neonatal outcomes were assessed using linear regression analyses including a quadratic effect (a square term) of the O/E PDA treatment ratio. RESULTS From 139 NICUs, 39 096 infants were included. The overall PDA treatment rate was 45% in the cohort (13%-77% by NICU) and the O/E PDA treatment ratio ranged from 0.30 to 2.14. The relationship between the O/E PDA treatment ratio and primary composite outcome was U-shaped, with the nadir at a ratio of 1.13 and a significant quadratic effect (P<.001). U-shaped relationships were also identified with death, severe neurologic injury, and necrotizing enterocolitis. CONCLUSIONS Both low and high PDA treatment rates were associated with death or severe neurologic injury, whereas a moderate approach was associated with optimal outcomes.

Abstract
OBJECTIVE The use of video laryngoscopy for intubating neonates in ergonomically challenging settings has not been studied well. We aimed to assess the usefulness of video laryngoscopy for experienced neonatologists to intubate neonatal manikins in incubators via side hand ports or head window. STUDY DESIGN In this randomized crossover trial at three neonatal intensive care units in Japan, 27 neonatologists were randomized into two groups, namely, those intubating neonatal simulators using video laryngoscopy and then using direct laryngoscopy, or vice versa. The intubations were performed via hand ports or head window without opening top and side walls in incubators in two manikin positions (rotated 90° or unrotated). Glottis visualization (0-100%), success rate, intubation time, and ease of laryngoscopy (from 1 [very difficult] to 10 [very easy]) were compared between video laryngoscopy and direct laryngoscopy. Generalized linear models were used for the analyses. RESULTS This study assessed 108 intubations performed by 27 neonatologists. The use of video laryngoscopy improved the glottis visualization by 14% (95% confidence interval, 7.4-20%; p < 0.01) and easiness scores of laryngoscopy by 0.8 (0.2-1.4; p < 0.01), but did not reduce the intubation time. CONCLUSION Video laryngoscopy is useful for experienced neonatologists for intubating neonatal manikins in incubators without opening the top or side walls.

Abstract
Background
Congenital high airway obstruction syndrome (CHAOS) is a rare disease and recently has been noticed to show typical prenatal images, such as hyperinflated lungs and flattened or inverted diaphragms. However, in some cases correct diagnosis may be difficult and in such cases the mortality rate increases.
Case presentation
We report four cases of CHAOS complicated with a high airway fistula to the alimentary tract and foregut malformation. The patients did not show the typical features of CHAOS in the fetus. This may be attributed to the high airway fistula acting as a decompression route for the accumulated lung fluids to the alimentary tract.
Conclusion
The combination of CHAOS, foregut malformation and a high airway fistula is very rare and classified into four distinct types: (1) CHAOS with a high airway fistula but not with a foregut malformation; (2) CHAOS with esophageal atresia and tracheoesophageal fistula; (3) CHAOS with a high airway fistula and duodenal atresia; and (4) CHAOS with esophageal atresia, tracheoesophageal fistula and duodenal atresia. It may be useful for treating physicians to be aware of these four distinct types and the typical characteristics of each type.

Abstract
Background Very preterm infants are at high risk of death or severe morbidity. The objective was to determine the significance of severe congenital heart defects (CHDs) for these risks. Methods and Results This cohort study included infants from 10 countries born from 2007–2015 at 24 to 31 weeks’ gestation with birth weights <1500 g. Severe CHDs were defined by International Classification of Diseases, Ninth Revision (ICD‐9) and Tenth (ICD‐10) codes and categorized as those compromising systemic output, causing sustained cyanosis, or resulting in congestive heart failure. The primary outcome was in‐hospital mortality. Secondary outcomes were neonatal brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity. Adjusted and propensity score–matched odds ratios (ORs) were calculated. Analyses were stratified by type of CHD, gestational age, and network. A total of 609 (0.77%) infants had severe CHD and 76 371 without any malformation served as controls. The mean gestational age and birth weight were 27.8 weeks and 1018 g, respectively. The mortality rate was 18.6% in infants with CHD and 8.9% in controls (propensity score–matched OR, 2.30; 95% CI, 1.61–3.27). Severe CHD was not associated with neonatal brain injury, necrotizing enterocolitis, or retinopathy of prematurity, whereas the OR for bronchopulmonary dysplasia increased. Mortality was higher in all types, with the highest propensity score–matched OR (4.96; 95% CI, 2.11–11.7) for CHD causing congestive heart failure. While mortality did not differ between groups at <27 weeks’ gestational age, adjusted OR for mortality in infants with CHD increased to 10.9 (95% CI, 5.76–20.70) at 31 weeks’ gestational age. Rates of CHD and mortality differed significantly between networks. Conclusions Severe CHD is associated with significantly increased mortality in very preterm infants.

Abstract
The Japan Resuscitation Council joined the International Liaison Committee on Resuscitation (ILCOR) as a member of the Resuscitation Council of Asia in 2006. In 2007, the Japan Society of Perinatal and Neonatal Medicine (JSPNM), which is a member of an affiliated body, launched the Neonatal Cardiopulmonary Resuscitation (NCPR) program as an authorized project to ensure that all staff involved in perinatal and neonatal medicine can learn and practice neonatal cardiopulmonary resuscitation based on the Consensus on Science with Treatment Recommendations developed by ILCOR. The content of courses in the NCPR program is based on the NCPR guidelines. These guidelines are revised by the Japan Resuscitation Council according to the Consensus on Science with Treatment Recommendations, which is updated by ILCOR every 5 years. The latest updated edition in Japanese was published in 2016 and we translated these Japanese guidelines to English in 2018. Here, we introduce a summary of the NCPR guidelines 2015 in Japan. The NCPR 2015 algorithm has two flows, "lifesaving flow" and "stabilization of breathing flow" at the first branching point after the initial step of resuscitation.

Abstract
The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research.

Abstract
In July 2007, the Neonatal Cardiopulmonary Resuscitation (NCPR) program in Japan was launched to ensure that all staff involved in perinatal and neonatal medicine can learn and practice NCPR based on the Consensus on Science with Treatment Recommendations developed by the International Liaison Committee on Resuscitation. In 1978 in North America, a working group on pediatric resuscitation was formed by the American Heart Association Emergency Cardiac Care Committee and concluded that the resuscitation of newborns required a different strategy than the resuscitation of adults. The original first edition of the Neonatal Resuscitation Program textbook was published in 1987. The NCPR program consists of three courses for health-care providers and two courses for instructors. A course and B course are for newly certified health-care providers and course S is for health-care providers who are renewing their certification. As of 31 March 2019, 3,227 advanced instructors (I instructor) and 1,877 basic instructors (J instructor) were trained to teach A, B, and S courses to health-care providers on the basis of their license. In total 7,075 A courses and 4,012 B courses were held; 131 651 people attended A course or B course of the NCPR program, and 77 367 were certified. A total of 1,865 S courses, which were developed in 2015, were held and 12 875 people attended this course. Here, we introduce the background, purpose, history, and content of the development of the NCPR program in Japan.

Abstract
There is a wide variation in neonatal mortality rates across regions and countries. Japan has one of the lowest neonatal mortality rates in the world; in particular, the mortality rate of extremely preterm infants (i.e., those born before 26 weeks of gestation) is much lower in Japan than in other developed countries. In addition, Japan has low incidences of intraventricular hemorrhage, necrotizing enterocolitis, and late-onset sepsis, a very high incidence of retinopathy of prematurity, and a relatively high incidence of chronic lung disease. In Japan, general perinatal medical centers (PMCs), which are PMCs that offer the highest levels of care, are required to have an obstetric department with maternal-fetal intensive care units as well as a neonatal or pediatric department with neonatal intensive care units (NICU), in order to promote antenatal rather than neonatal maternal transfer of high-risk cases. The limit of viability of extremely preterm infants is 22 weeks of gestation, and approximately half of them are estimated to receive active resuscitation. The clinical management of extremely preterm infants in Japan are characterized by (I) circulatory management that is guided by neonatologist-performed echocardiography, (II) relatively invasive respiratory management, (III) nutritional management, which entails the promotion of breast milk feeding, early enteral feeding, routine glycerin enema, and the administration of probiotics, (IV) neurological management by means of minimal handling, sedation of ventilated infants, and serial brain ultrasounds, and (V) infection control with the assistance of serial C-reactive protein (CRP) monitoring. Thus, this review provides a brief description of the development of neonatology in Japan, introduces the unique features of Japanese clinical management of extremely preterm infants, and overviews their outcomes.

Abstract
OBJECTIVE To compare neurodevelopmental outcomes of preterm infants at 18-21 months corrected age (CA) whose mothers smoked during pregnancy to those whose mothers did not smoke. STUDY DESIGN Preterm infants born at <29 weeks of gestation and evaluated at 18-21 months CA were included. Primary outcome was a composite outcome of death or neurodevelopmental impairment (NDI). RESULTS Of a total of 2760 infants, 699 met exclusion criteria. Of the remaining 2061 infants, 280 (13.6%) were exposed to maternal smoking and 1781 (86.4%) were not. The odds of the composite outcome of death or NDI (aOR 1.40; 95% CI: 1.03-1.91), NDI alone (aOR 1.43; 95% CI: 1.01-2.03), and Bayley-III motor score <85 (aOR 1.91; 95% CI: 1.31-2.81) were higher in exposed infants. CONCLUSIONS Exposure to maternal smoking was associated with adverse composite outcome of death or NDI, NDI alone and lower motor scores at 18-21 months CA.

OBJECTIVES This systematic review and meta-analysis provides the scientific summary of initial Fio2 in preterm newborns (<35 weeks' gestation) who receive respiratory support at birth. DATA SOURCES Medline, Embase, Evidence-Based Medicine Reviews, and Cumulative Index to Nursing and Allied Health Literature were searched between January 1, 1980 and August 10, 2018. STUDY SELECTION Studies were selected by pairs of independent reviewers in 2 stages with a Cohen's κ of 0.8 and 1.0. DATA EXTRACTION Pairs of independent reviewers extracted data, appraised the risk of bias (RoB), and assessed Grading of Recommendations Assessment, Development and Evaluation certainty. RESULTS Ten randomized controlled studies and 4 cohort studies included 5697 patients. There are no statistically significant benefits of or harms from starting with lower compared with higher Fio2 in short-term mortality (n = 968; risk ratio = 0.83 [95% confidence interval 0.50 to 1.37]), long-term mortality, neurodevelopmental impairment, or other key preterm morbidities. A sensitivity analysis in which 1 study with a high RoB was excluded failed to reveal a reduction in mortality with initial low Fio2 (n = 681; risk ratio = 0.63 [95% confidence interval 0.38 to 1.03]). LIMITATIONS The Grading of Recommendations Assessment, Development and Evaluation certainty of evidence was very low for all outcomes due to RoB, inconsistency, and imprecision. CONCLUSIONS The ideal initial Fio2 for preterm newborns is still unknown, although the majority of newborns ≤32 weeks' gestation will require oxygen supplementation.

Abstract
INTRODUCTION The availability of and variability in healthcare professionals in neonatal units in different countries has not been well characterized. Our objective was to identify variations in the healthcare professionals for preterm neonates in 10 national or regional neonatal networks participating in the International Network for Evaluating Outcomes (iNeo) of neonates. METHOD Online, pre-piloted questionnaires about the availability of healthcare professionals were sent to the directors of 390 tertiary neonatal units in 10 international networks: Australia/New Zealand, Canada, Finland, Illinois, Israel, Japan, Spain, Sweden, Switzerland, and Tuscany. RESULTS Overall, 325 of 390 units (83%) responded. About half of the units (48%; 156/325) cared for 11-30 neonates/day and had team-based (43%; 138/325) care models. Neonatologists were present 24 h a day in 59% of the units (191/325), junior doctors in 60% (194/325), and nurse practitioners in 36% (116/325). A nurse-to-patient ratio of 1:1 for infants who are unstable and require complex care was used in 52% of the units (170/325), whereas a ratio of 1:1 or 1:2 for neonates requiring multisystem support was available in 59% (192/325) of the units. Availability of a respiratory therapist (15%, 49/325), pharmacist (40%, 130/325), dietitian (34%, 112/325), social worker (81%, 263/325), lactation consultant (45%, 146/325), parent buddy (6%, 19/325), or parents' resource personnel (11%, 34/325) were widely variable between units. CONCLUSIONS We identified variability in the availability and organization of the healthcare professionals between and within countries for the care of extremely preterm neonates. Further research is needed to associate healthcare workers' availability and outcomes.

DATA EXTRACTION Pairs of independent reviewers extracted data, appraised risk of bias, and assessed Grading of Recommendations Assessment, Development and Evaluation certainty of evidence. RESULTS Five randomized controlled trials (RCTs) and 5 quasi RCTs included 2164 patients. Room air (Fio2 0.21) was associated with a statistically significant benefit in short-term mortality compared with 100% oxygen (Fio2 1.0) (7 RCTs; n = 1469; risk ratio [RR] = 0.73; 95% confidence interval [CI]: 0.57 to 0.94). No significant differences were observed in neurodevelopmental impairment (2 RCTs; n = 360; RR = 1.41; 95% CI: 0.77 to 2.60) or hypoxic-ischemic encephalopathy (5 RCTs; n = 1315; RR = 0.89; 95% CI: 0.68 to 1.18). LIMITATIONS The Grading of Recommendations Assessment, Development and Evaluation certainty of evidence was low for short-term mortality and hypoxic-ischemic encephalopathy and very low for neurodevelopmental impairment. CONCLUSIONS Room air has a 27% relative reduction in short-term mortality compared with Fio2 1.0 for initiating neonatal resuscitation ≥35 weeks' gestation.

Abstract
OBJECTIVE The aim of this study was to evaluate the association between neonatal seizure and neurodevelopmental impairment (NDI) at 18 to 24 months in extremely preterm neonates. The association between anticonvulsants use and NDI was also assessed. STUDY DESIGN In this retrospective cohort study of infants born at <29 weeks' gestation from the Canadian Neonatal Network and Canadian Neonatal Follow-Up Network databases, we compared mortality and neurodevelopmental outcomes in infants who had neonatal seizures with those without seizures after adjusting for confounders. RESULTS Of the 2,762 eligible neonates, 133 (4.8%) had seizures. Infants who had seizures were of lower gestation (25.2 vs. 26.2 weeks) and birth weight (819 vs. 920 g) and had higher rates of adverse outcomes. Neonatal seizure was associated with higher odds of composite outcome of death or significant NDI (74 vs. 27%; adjusted odds ratio [OR]: 3.4; 95% confidence interval [CI]: 2.2-5.4). Death or significant NDI was higher in infants with seizures treated with anticonvulsants than those without treatment (89 vs. 70%); however, when adjusted for confounders, it was not significantly different (adjusted OR: 3.5; 95% CI: 0.83-14.6). CONCLUSION Neonatal seizures were independently associated with higher odds of death or significant NDI at 18 to 24 months of age. Relationship of anticonvulsant and neurodevelopmental outcomes needs further studies.
