Abstract
BACKGROUND Neonatal intensive care unit (NICU) admission among term neonates is a rare event. The aim of this study was to study the association of the NICU admission of term neonates on the risk of long-term childhood mortality. METHODS A single-center case-control retrospective study between 2005 and 2019, including all in-hospital ≥ 37 weeks' gestation singleton live-born neonates. The center perinatal database was linked with the birth and death certificate registries of the Israeli Ministry of Internal Affairs. The primary aim of the study was to study the association between NICU admission and childhood mortality throughout a 15-year follow-up period. RESULTS During the study period, 206,509 births were registered; 192,527 (93.22%) term neonates were included in the study; 5292 (2.75%) were admitted to NICU. Throughout the follow-up period, the mortality risk for term neonates admitted to the NICU remained elevated; hazard ratio (HR), 19.72 [14.66, 26.53], (p < 0.001). For all term neonates, the mortality rate was 0.16% (n = 311); 47.9% (n = 149) of those had records of a NICU admission. The mortality rate by time points (ratio1:10,0000 births) related to the age at death during the follow-up period was as follows: 29, up to 7 days; 20, 7-28 days; 37, 28 days to 6 months; 21, 6 months to 1 year; 19, 1-2 years; 9, 2-3 years; 10, 3-4 years; and 27, 4 years and more. Following the exclusion of congenital malformations and chromosomal abnormalities, NICU admission remained the most significant risk factor associated with mortality of the study population, HRs, 364.4 [145.3; 913.3] for mortality in the first 7 days of life; 19.6 [12.1; 32.0] for mortality from 28 days through 6 months of life and remained markedly elevated after age 4 years; HR, 7.1 [3.0; 17.0]. The mortality risk related to the NICU admission event, adjusted for admission diagnoses remained significant; HR = 8.21 [5.43; 12.4]. CONCLUSIONS NICU admission for term neonates is a pondering event for the risk of long-term childhood mortality. This group of term neonates may benefit from focused health care.

Abstract
ABSTRACT This study aims to analyze why we should care about full-term newborns admitted to a neonatal intensive care unit. This is a documented, descriptive, and retrospective study of 262 full-term newborns. Variables used: newborns’ characteristics; main diagnosis, length of stay, follow-up by a multidisciplinary team; post-discharge referral. Most newborns were boys (52%), had a 5-minute Apgar score of nine, and most newborns and their mothers were white (61.1% and 48.9% respectively). Respiratory dysfunction was the main diagnosis (28.8%). Length of stay was eight days. There was a significant difference regarding length of stay (p=0.013), in which those with cardiorespiratory and other diseases stayed less time compared to those with malformation or maternal diseases. The social service was the most sought (81.2%) service, whereas physical therapy the least sought (18%). Newborns with higher weight were hospitalized for less time. Those that underwent physical therapy had longer stay (p<0.001). Main outcome was hospital discharge (68.7%) and referrals to the Basic Health Unit (57%). This study outcomes indicated newborns with less severe conditions, low number of specific studies for the full-term population, other diagnoses that refer to non-intensive care.

Abstract
RESUMO O objetivo deste estudo foi analisar a razão pela qual devemos nos preocuparmos com os bebês a termo internados em uma unidade de terapia intensiva neonatal. Trata-se de estudo documental, descritivo e retrospectivo de 262 recém-nascidos (RNs) a termo. As variáveis utilizadas foram: características dos RN; diagnóstico principal, tempo de permanência e acompanhamento pela equipe multiprofissional; e encaminhamento pós-alta. Houve prevalência do sexo masculino (52%), de Apgar 9 no 5º minuto e da raça/cor branca do RN e da mãe (61,1% e 48,9%, respectivamente). O diagnóstico principal foi a disfunção respiratória (28,8%), e o tempo de permanência foi de oito dias. Houve diferença significativa entre os tempos de permanência (p=0,013), em que as doenças cardiorrespiratórias e outras doenças levaram a um menor tempo de internação em relação à má formação ou às doenças maternas. O serviço social foi o mais procurado para o acompanhamento (81,2%) e a fisioterapia, o menos buscado (18%). RNs com maior peso ficaram menos tempo internados, e os acompanhados por fisioterapia apresentaram tempo de permanência mais elevados (p<0,001). O principal desfecho foi a alta hospitalar (68,7%) e encaminhamentos para a Unidade Básica de Saúde (57%). Os achados deste estudo apontam a presença de bebês menos graves, baixo número de estudos específicos para a população a termo e outros diagnósticos que nos remetem a cuidados não intensivos.

NICU Admission for Term Neonates in a Large Single-Center Population: A Comprehensive Assessment of Risk Factors Using a Tandem Analysis Approach. J Clin Med 2022; 11:jcm11154258. [PMID: 35893346 PMCID: PMC9332268 DOI: 10.3390/jcm11154258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/15/2022] [Accepted: 07/19/2022] [Indexed: 11/16/2022] Open
Abstract
Objective: Neonatal intensive care unit (NICU) admission among term neonates is associated with significant morbidity and mortality, as well as high healthcare costs. A comprehensive NICU admission risk assessment using an integrated statistical approach for this rare admission event may be used to build a risk calculation algorithm for this group of neonates prior to delivery. Methods: A single-center case−control retrospective study was conducted between August 2005 and December 2019, including in-hospital singleton live born neonates, born at ≥37 weeks’ gestation. Analyses included univariate and multivariable models combined with the machine learning gradient-boosting model (GBM). The primary aim of the study was to identify and quantify risk factors and causes of NICU admission of term neonates. Results: During the study period, 206,509 births were registered at the Shaare Zedek Medical Center. After applying the study exclusion criteria, 192,527 term neonates were included in the study; 5292 (2.75%) were admitted to the NICU. The NICU admission risk was significantly higher (ORs [95%CIs]) for offspring of nulliparous women (1.19 [1.07, 1.33]), those with diabetes mellitus or hypertensive complications of pregnancy (2.52 [2.09, 3.03] and 1.28 [1.02, 1.60] respectively), and for those born during the 37th week of gestation (2.99 [2.63, 3.41]; p < 0.001 for all), adjusted for congenital malformations and genetic syndromes. A GBM to predict NICU admission applied to data prior to delivery showed an area under the receiver operating characteristic curve of 0.750 (95%CI 0.743−0.757) and classified 27% as high risk and 73% as low risk. This risk stratification was significantly associated with adverse maternal and neonatal outcomes. Conclusion: The present study identified NICU admission risk factors for term neonates; along with the machine learning ranking of the risk factors, the highly predictive model may serve as a basis for individual risk calculation algorithm prior to delivery. We suggest that in the future, this type of planning of the delivery will serve different health systems, in both high- and low-resource environments, along with the NICU admission or transfer policy.

Abstract
Abstract Introduction Two facts may influence a newborn’s development. One is to be a newborn at risk and the other is to be hospitalized in Intensive Care Unit. Objective To examine where at-risk infants are being referred for longitudinal follow-up after hospital discharge, and to carry out an analysis of the epidemiological and care profile of these babies. Methods Documentary, descriptive and retrospective study, comprising the medical records of 479 newborns (NBs) hospitalized Hospital Materno Infantil Presidente Vargas from January 2019 to May 2020. The variables studied were: gender, baby's race/color, type of delivery, prenatal consultations, classification according to gestational age, weight, Apgar of the 1st, 5th, 10th minute, hospitalization diagnosis, main diagnosis, outcomes, length of stay, multidisciplinary follow-up during hospitalization, post-discharge referrals (specialized and non-specialized). Social and environmental data were: maternal age and race/color, maternal and paternal education. Results Higher prevalence of full-term male babies born by cesarean delivery, declared as white, with high Apgar scores, with varied diagnoses, with prematurity prevailing. Maternal mean was 26.2 years, (SD ± 7.3), the most reported race/color was also white, the mean of mothers' studies was 8.1 years (SD ± 2.4). Only 14% (n = 67) performed motor physical therapy at the hospital and 2.1% (n = 10) were referred for evaluation and early intervention for post-discharge physical therapy. The specialized service with the highest referral was the hospital's neuropediatrics graduates' outpatient clinic (17.3%, n = 83) and, for the non-specialized, it was the Basic Health Unit/BHU (39.7%, n = 190). Conclusion Most NBs are referred to the specific medical team or post-discharge BHU. The physiotherapist was the professional little remembered for monitoring this public in the hospital and after discharge.

Abstract
OBJECTIVES To determine the incidence of and risk factors for neonatal unit admission, intrapartum stillbirth or neonatal death without admission, and describe outcomes, in babies born in an alongside midwifery unit (AMU). DESIGN National population-based case-control study. METHOD We used the UK Midwifery Study System to identify and collect data about 1041 women who gave birth in AMUs, March 2017 to February 2018, whose babies were admitted to a neonatal unit or died (cases) and 1984 controls from the same AMUs. We used multivariable logistic regression, generating adjusted OR (aOR) with 95% CIs, to investigate maternal and intrapartum factors associated with neonatal admission or mortality. RESULTS The incidence of neonatal admission or mortality following birth in an AMU was 1.2%, comprising neonatal admission (1.2%) and mortality (0.01%). White 'other' ethnicity (aOR=1.28; 95% CI=1.01 to 1.63); nulliparity (aOR=2.09; 95% CI=1.78 to 2.45); ≥2 previous pregnancies ≥24 weeks' gestation (aOR=1.38; 95% CI=1.10 to 1.74); male sex (aOR=1.46; 95% CI=1.23 to 1.75); maternal pregnancy problem (aOR=1.40; 95% CI=1.03 to 1.90); prolonged (aOR=1.42; 95% CI=1.01 to 2.01) or unrecorded (aOR=1.38; 95% CI=1.05 to 1.81) second stage duration; opiate use (aOR=1.31; 95% CI=1.02 to 1.68); shoulder dystocia (aOR=5.06; 95% CI=3.00 to 8.52); birth weight <2500 g (aOR=4.12; 95% CI=1.97 to 8.60), 4000-4999 g (aOR=1.64; 95% CI=1.25 to 2.14) and ≥4500 g (aOR=2.10; 95% CI=1.17 to 3.76), were independently associated with neonatal admission or mortality. Among babies admitted (n=1038), 18% received intensive care. Nine babies died, six following neonatal admission. Sepsis (52%) and respiratory distress (42%) were the most common discharge diagnoses. CONCLUSIONS The results of this study are in line with other evidence on risk factors for neonatal admission, and reassuring in terms of the quality and safety of care in AMUs.

Abstract
Background: Subclinical hypothyroidism (SCH) and thyroid autoimmunity (TAI) have been associated with poor clinical pregnancy outcomes. However, these outcomes also depend on a number of demographic and obstetric variables. Therefore, the aim of this study was to investigate the impact of thyroid disorders on these outcomes, after adjustment for associated demographic and obstetrical parameters. Methods: This is cross-sectional study including 1521 pregnant women who underwent work-up and follow-up in the Centre Hospitalier Universitaire (CHU) Saint-Pierre, Brussels, and had ongoing pregnancies. Thyroid function (thyrotropin [TSH], free thyroxine [fT4]) and TAI (thyroid peroxidase antibodies) was determined at median (Q1-Q3) 13 (11-17) weeks. Baseline parameters and the prevalence of poor clinical pregnancy outcomes were compared between controls (no TAI and TSH <2.51 mIU/L) and three study groups (isolated TAI [TSH <2.51 mIU/L], SCH1 [TSH 2.51-3.7 mIU/L], SCH2 [TSH >3.7 mIU/L]). The impact of the different thyroid groups and demographic/obstetric independent variables on six poor clinical pregnancy outcomes (preeclampsia, intrauterine growth restriction [IUGR], preterm birth, neonatal intensive care unit [NICU] admission, low birth weight, and macrosomia) was investigated in a logistic regression model. Treatment with thyroid hormone before and during pregnancy and assisted and multiple pregnancies were exclusion criteria. Results: In total, 79 preeclampsias (5.2%), 40 IUGRs (2.6%), 79 preterm births (5.2%), 10 admissions to NICU (0.66%), 74 low birth weights (4.9%), and 94 babies with macrosomia (6.2%) were documented. TAI was independently associated with NICU admission (adjusted odds ratio [aOR] 16.92 confidence interval [CI 3.36-85.29]; p < 0.001) and TSH, as a continuous variable in the whole range, with preeclampsia (aOR 1.97 [CI 1.18-3.31]; p = 0.010). Trends were present for an association between SCH2 and preeclampsia (aOR 16.73 [CI 1.43-196.42]; p = 0.025), and for SCH1with NICU admission and low birth weight (aOR 19.36 [CI 1.18-316.97]; p = 0.038 and 21.38 [CI 1.29-353.39]; p = 0.032, respectively). Conclusions: Pregnant women with TAI had a significantly higher risk of an admission of the baby to the NICU, and SCH tended to be associated with a higher risk of preeclampsia and low birth weight. Other poor clinical pregnancy outcomes were not associated with thyroid disorders, but with demographic and obstetric parameters.

Abstract
Background Caesarean sections (CSs) are associated with increased maternal and perinatal morbidity, yet rates continue to increase within most countries. Effective interventions are required to reduce the number of non-medically indicated CSs and improve outcomes for women and infants. This paper reports findings of a systematic review of literature related to maternity service organisational interventions that have a primary intention of improving CS rates. Method A three-phase search strategy was implemented to identify studies utilising organisational interventions to improve CS rates in maternity services. The database search (including Cochrane CENTRAL, CINAHL, MEDLINE, Maternity and Infant Care, EMBASE and SCOPUS) was restricted to peer-reviewed journal articles published from 1 January 1980 to 31 December 2017. Reference lists of relevant reviews and included studies were also searched. Primary outcomes were overall, planned, and unplanned CS rates. Secondary outcomes included a suite of birth outcomes. A series of meta-analyses were performed in RevMan, separated by type of organisational intervention and outcome of interest. Summary risk ratios with 95% confidence intervals were presented as the effect measure. Effect sizes were pooled using a random-effects model. Results Fifteen articles were included in the systematic review, nine of which were included in at least one meta-analysis. Results indicated that, compared with women allocated to usual care, women allocated to midwife-led models of care implemented across pregnancy, labour and birth, and the postnatal period were, on average, less likely to experience CS (overall) (average RR 0.83, 95% CI 0.73 to 0.96), planned CS (average RR 0.75, 95% CI 0.61 to 0.93), and episiotomy (average RR 0.84, 95% CI 0.74 to 0.95). Narratively, audit and feedback, and a hospital policy of mandatory second opinion for CS, were identified as interventions that have potential to reduce CS rates. Conclusion Maternity service leaders should consider the adoption of midwife-led models of care across the maternity episode within their organisations, particularly for women classified as low-risk. Additional studies are required that utilise either audit and feedback, or a hospital policy of mandatory second opinion for CS, to facilitate the quantification of intervention effects within future reviews.

Abstract
: Thrombocytopenia has been closely associated with small-for-gestational-age neonates (SGA; birthweight less than tenth percentile) admitted to the special care nursery or neonatal ICU. It is unclear if 'well' SGA neonates experience the same incidence of thrombocytopenia in the SGA population as compared to sick neonates. We conducted a retrospective cohort study from a health network in Melbourne, Australia, between 2012 and 2015 to identify SGA neonates (≥ 35 weeks' gestation at birth) that were otherwise well. Neonates with at least one platelet count within 7 days of life were matched to appropriate-for-gestational-age (AGA) neonates from the same birth centre, with the same sex, and closest gestational age and birth date, who were also considered otherwise well. 16.7% of matched neonates had thrombocytopenia (303/1814) and of these, a larger proportion of SGA neonates were thrombocytopenic, 21.7% (197/907), than AGA neonates, 11.7% (106/907, P < 0.01). The incidence of thrombocytopenia was greater in the SGA cohort regardless of admission destination (special care nursery/neonatal ICU 26.8 vs. 13.9%, P < 0.01; Postnatal Ward 16.5 vs. 9.4%, P < 0.01). Thrombocytopenia is more prevalent amongst constitutionally well SGA neonates than AGA neonates. SGA alone increases the risk of thrombocytopenia.

Abstract
BACKGROUND An increasing number of term infants of appropriate birthweight receive care in neonatal intensive care units (NICUs). OBJECTIVES This study assessed the prevalence, patterns, and risk factors for admission of term infants to a NICU to identify areas for quality improvement. DESIGN Cross-sectional analytical study. SETTING An academic and referral center in Jeddah, Saudi Arabia. PATIENTS AND METHODS The cases were all term infants (>=37 weeks gestational age) admitted to the NICU between 1 January and 31 December 2015. The controls were term infants who were not admitted to the NICU. Cases and controls were matched in a 1:1 ratio according to the date of birth (within one day). MAIN OUTCOME MEASURES Prevalence, pattern, and risk factors for admission of term infants to the NICU. RESULTS The rate of admission of term infants to the NICU during the study period was 4.1% (142 of 3314 live births in that year). Respiratory complications accounted for 36.6% (52/142) of admissions, followed by hypoglycemia (23/142, 16.2%) and jaundice (11/142, 7.7%). Premature membrane rupture and non-Saudi national status were the risk factors that remained significant after adjusting for confounders. CONCLUSION A growing number of term infants are admitted unexpectedly to the NICU. The risk factors and pattern of admission of term infants to the NICU should receive more attention in quality improvement and management agendas. LIMITATIONS This was a single-center study with limited access to information about unbooked mothers and details of the hospital stay of the admitted neonates.

Abstract
Lower blood glucose values are common in the healthy neonate immediately after birth as compared to older infants, children, and adults. These transiently lower glucose values improve and reach normal ranges within hours after birth. Such transitional hypoglycemia is common in the healthy newborn. A minority of neonates experience a more prolonged and severe hypoglycemia, usually associated with specific risk factors and possibly a congenital hypoglycemia syndrome. Despite the lack of a specific blood glucose value that defines hypoglycemia, concern for substantial neurologic morbidity in the neonatal population has led to the generation of guidelines by both the American Academy of Pediatrics (AAP) and the Pediatric Endocrine Society (PES). Similarities between the 2 guidelines include recognition that the transitional form of neonatal hypoglycemia likely resolves within 48 hours after birth and that hypoglycemia that persists beyond that duration may be pathologic. One major difference between the 2 sets of guidelines is the goal blood glucose value in the neonate. This article reviews transitional and pathologic hypoglycemia in the neonate and presents a framework for understanding the nuances of the AAP and PES guidelines for neonatal hypoglycemia.

Abstract
OBJECTIVE To determine antepartum and intrapartum factors that are associated with admission to neonatal intensive care unit (NICU) among infants delivered between 36.0 and 42.0 weeks at our institution. METHODS The retrospective cohort study included 73 consecutive NICU admissions and 375 consecutive non-NICU admissions. Data on demographic, antepartum, intrapartum and neonatal factors were collected. The primary endpoint defined was admission to NICU. Univariate analyses using the Student's t-test, Mann-Whitney U-test, χ2 Fisher's exact test was performed along with multivariate analysis of significant non-redundant variables. RESULTS Those with a significantly higher risk of NICU admission underwent induction of labor with prostaglandin analogs (12.5% vs. 24.7%, P=0.007). Length of first stage ≥720 min (33.5% vs. 51.9%, P=0.011), length of second stage of labor ≥240 min (10.6% vs. 31.6%, P<0.001) and prolonged rupture of membranes ≥120 min (54.0% vs. 80.0%, P=0.001) were all associated with an increased chance of NICU admission. Intrapartum factors predictive of NICU admission included administration of meperidine (11.7% vs. 27.4%, P<0.001), presence of preeclampsia (5.5% vs. 0.8%, P=0.015), use of intrapartum IV antihypertensives (1.1% vs. 13.7%, P<0.001), maternal fever (5.3% vs. 31.5%, P<0.001), fetal tachycardia (1.9% vs. 12.3%, P<0.001), and presence of meconium (30% vs. 8%, P<0.001). CONCLUSION Identification of modifiable risk factors may reduce neonatal morbidity and mortality. Results from this study can be used to develop and validate a risk model based on combined antepartum and intrapartum risk factors.

Abstract
OBJECTIVE The purpose of this study was to identify electronic fetal monitoring patterns that are associated with neonatal respiratory morbidity. STUDY DESIGN In an on-going prospective cohort study of >8000 consecutive term, vertex, nonanomalous singleton pregnancies during labor, we performed this analysis within the first 5000 women as a representative sample. Electronic fetal monitoring patterns in the 30 minutes preceding delivery were extracted by trained obstetrics research nurses, who were blinded to clinical data, using the National Institute of Child Health and Human Development system; the data were compared between those with respiratory morbidity and healthy infants (no morbidities). The primary outcome was neonatal respiratory morbidity, which was defined as either oxygen requirement at ≥6 hours of life or any mechanical ventilation in the first 24 hours. Multivariable logistic regression was used to adjust for confounders. RESULTS Of 4736 neonates, 175 (3.4%) experienced respiratory morbidity. Most electronic fetal monitoring patterns were category II (96.6%; n = 4575). Baseline tachycardia (adjusted odds ratio [aOR], 2.9; 95% confidence interval [CI], 1.9-4.4), marked variability (aOR, 2.7; 95% CI, 1.5-5.0), and prolonged decelerations (aOR,2.7; 95% CI, 1.5-5.0) were significantly associated with an increased likelihood of term neonatal respiratory morbidity. Accelerations and persistent moderate variability were both significantly associated with a decreased likelihood of respiratory morbidity. CONCLUSION Specific features of category II electronic fetal monitoring patterns make respiratory morbidity more likely in nonanomalous term infants. Tachycardia, marked variability, or prolonged decelerations before delivery can assist providers in anticipating the potential need for neonatal respiratory support.

Abstract
OBJECTIVE Fetal cerebroplacental ratio is emerging as a better proxy than birthweight for placental insufficiency and as a marker of fetal compromise at term. The extent to which these fetal Doppler changes are related to neonatal outcomes has not been systematically assessed. The main aim of this study was to evaluate the association between estimated fetal weight percentile, cerebroplacental ratio recorded at 34(+0)-35(+6) weeks' gestation, and neonatal unit admission at term. STUDY DESIGN This was a retrospective cohort study in a tertiary referral center over an 11 year period from 2002 to 2012. The umbilical artery pulsatility index (PI), middle cerebral artery PI, and cerebroplacental ratio were recorded at 34(+0)-35(+6) weeks. Weight values were converted into percentiles and Doppler parameters into multiples of the median (MoM), adjusting for gestational age. Logistic regression analysis was performed to identify, and adjust for, potential confounders. RESULTS We identified 2518 pregnancies in which a scan was performed at 34(+0)-35(+6) weeks and delivery occurred at or beyond 37 weeks. In the 2485 pregnancies included in the analysis, the umbilical artery PI MoM was significantly higher, and the middle cerebral artery PI and cerebroplacental ratio MoM significantly lower in the babies requiring neonatal unit admission (P < .05). However, the estimated fetal weight percentile was not significantly different between those who required neonatal unit admission and those who did not (P = .087). According to multivariate logistic regression, cerebroplacental ratio MoM (odds ratio, 0.39; 95% confidence interval, 0.19-0.79; P = .008) and gestational age at delivery (odds ratio, 0.70; 95% confidence interval, 0.61-0.80; P < .001) were significantly associated with the risk of neonatal unit admission, whereas maternal age and birthweight percentile were not (P = .183 and P = .460, respectively). Irrespective of birthweight or estimated fetal weight percentile, the fetal cerebroplacental ratio appears to be a better predictor of the need for neonatal unit admission (P < .001). CONCLUSION Lower cerebroplacental ratio and gestational age at delivery, but not fetal size, were independently associated with the need for admission to the neonatal unit at term in a high-risk patient group. The extent to which fetal hemodynamic assessment could be used to predict perinatal morbidity and optimize the timing of delivery merits further investigation.

Abstract
OBJECTIVE The purpose of this study was to identify ante- and intrapartum risk factors for serious morbidity in term nonanomalous neonates. STUDY DESIGN We analyzed the first 5000 subjects within an ongoing prospective cohort study of consecutive term births from 2010-2012. The primary outcome was a composite of serious neonatal morbidity defined as ≥1 cases of hypoxic ischemic encephalopathy, meconium aspiration with pulmonary hypertension, requirement of hypothermia therapy, respiratory distress syndrome, seizures, sepsis or suspected sepsis, or death. We calculated odds ratios for the composite morbidity that is associated with ante- and intrapartum factors. Multivariable logistic regression was used to estimate adjusted odds ratios. RESULTS Of 5000 term nonanomalous births, 393 had the composite morbidity. Significant risk factors for morbidity were nulliparity, presence of meconium, first stage of labor >95th percentile, second stage of labor >95th percentile, pregestational diabetes mellitus, chronic hypertension, obesity, maternal intrapartum fever, and cesarean delivery. In contrast, induction of labor and gestational age ≥41 weeks were not associated with significant morbidity. CONCLUSION We identified several significant risk factors for serious morbidity in term nonanomalous neonates. Clinicians may use these risk factors to help anticipate the potential need for additional neonatal support at delivery.

Abstract
OBJECTIVE Current intra-partum monitoring techniques are often criticized for their poor specificity, with their performance frequently evaluated using measures of the neonatal condition at birth as a surrogate marker for intra-partum fetal compromise. However, these measures may potentially be influenced by a multitude of other factors, including the mode of delivery itself. This study aimed to investigate the impact of mode of delivery on neonatal condition at birth. STUDY DESIGN This prospective observational study, undertaken at a tertiary referral maternity unit in London, UK, included 604 'low risk' women recruited prior to delivery. Commonly assessed neonatal outcome variables (Apgar score at 1 and 5min, umbilical artery pH and base excess, neonatal unit admission, and a composite neonatal outcome score) were used to compare the condition at birth between babies born by different modes of delivery, using one-way ANOVA and chi-squared testing. RESULTS Infants born by instrumental delivery for presumed fetal compromise had the poorest condition at birth (mean composite score=1.20), whereas those born by Cesarean section for presumed fetal compromise had a better condition at birth (mean composite score=0.64) (p=<0.001). No difference in composite neonatal outcome scores was observed between babies born by instrumental delivery for a prolonged second stage (no evidence of compromise), and those born by Cesarean delivery for presumed fetal compromise. CONCLUSIONS Mode of delivery represents a potential confounding factor when using condition at birth as a surrogate marker of intra-partum fetal compromise. When evaluating the efficacy of intra-partum monitoring techniques, the isolated use of Apgar scores, umbilical artery acidosis and neonatal unit admission should be discouraged.

Abstract
BACKGROUND Births by elective caesarean section (CS) are rising, particularly before 39 weeks' gestation, which may be associated with unacceptably high risk of adverse neonatal outcomes. The optimal timing of these deliveries needs to be determined with recent recommendations to delay births by elective CS until 39 weeks. AIMS To evaluate the association between gestational age (GA) at delivery and neonatal outcomes after elective CS between 37 and 41 weeks. MATERIALS AND METHODS Retrospective cohort study of viable singleton neonates delivered by elective CS at Mater Mothers' Hospitals (1998-2009). Neonates were stratified into two GA groups with early term (ET, 37-38 weeks) compared with the reference group of full and late term (FLT, 39-41 weeks). The primary outcome examined was serious respiratory morbidity; secondary outcomes included depression at birth, nursery admission and assisted ventilation. RESULTS Fourteen thousand and four hundred and forty-seven mother-baby pairs were included (59.9% delivered before 39 weeks). There was a significantly decreasing risk of adverse neonatal outcomes with increasing GA. Compared to FLT, delivery at ET almost tripled the risk of the primary outcome (AOR 2.74; 95% CI 1.79-4.21). Rates of most secondary outcomes were at least doubled. CONCLUSION Elective CS performed at 37-38 weeks is associated with poorer neonatal outcomes compared to those delivered at 39-41 weeks. This study supports recent recommendations to delay delivery by elective CS until week 39 if possible.
