Small-for-gestational-age (SGA) infants have been associated with increased risk of adverse perinatal outcomes (APOs). In this work, we assess the predictive ability of the ultrasound-estimated percentile weight (EPW) at 35 weeks of gestational age to predict late-onset SGA and APOs, according to six growth standards, and whether the ultrasound–delivery interval influences the detection rate. To this purpose, we analyze a retrospective cohort study of 9585 singleton pregnancies. EPWs at 35 weeks were calculated to the customized Miguel Servet University Hospital (MSUH) and Figueras standards and the non-customized MSUH, Fetal Medicine Foundation (FMF), INTERGROWTH-21st, and WHO standards. As results of our analysis, for a 10% false positive rate, the detection rates for SGA ranged between 48.9% with the customized Figueras standard (AUC 0.82) and 60.8% with the non-customized FMF standard (AUC 0.87). Detection rates to predict SGA by ultrasound–delivery interval (1–6 weeks) show higher detection rates as intervals decrease. APOs detection rates ranged from 27.0% with FMF to 7.9% with the Figueras standard. In conclusion, the ability of EPW to predict SGA at 35 weeks is good for all standards, and slightly better for non-customized standards. The APO detection rate is significantly greater for non-customized standards.

Abstract Purpose To describe the perinatal outcome of a prospective cohort of late-onset small-for-gestational-age (SGA) fetuses and to test adverse perinatal outcome (APO) prediction using Doppler measurements. Methods Singleton pregnancies from 32 weeks with suspicion of SGA (followed-up each 2 weeks) and randomly selected healthy controls at a university hospital were included. The whole SGA group was divided into the FGR subgroup or SGA percentile 3–10 subgroup. The following Doppler measurements were evaluated prospectively: umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, cerebro-placental ratio (CPR), and mean uterine artery (mUtA) PI. APO was defined as arterial cord blood pH ≤ 7.15 and/or 5-minute Apgar ≤ 7 and/or emergency operative delivery and/or admission to the neonatal unit. Induction of labor was indicated according to a stage-based protocol. Results A total of 149 SGA and 143 control fetuses were included. The number of operative deliveries was similar between both groups (control: 29 %, SGA: 28 %), especially the cesarean delivery rate after the onset of labor (11 % vs. 10 %). Most SGA cases ended up in induction of labor (61 % vs. 31 %, p < 0.001). The areas under the curve (AUC) for APO prediction were similar using the last UA PI, MCA PI, CPR, and mUtA PI and barely reached 0.60. The AUC was best for the FGR subgroup, using the minimal CPR or maximum mUtA PI z-score of all longitudinal measurements (AUC = 0.63). Conclusion SGA fetuses do not have a higher rate of operative delivery if managed according to a risk stratification protocol. Prediction of APO is best for SGA and FGR using the “worst” CPR or mUtA PI but it remains moderate.

PurposeThe aim of this study was to assess morbidity and mortality pattern of small for gestational age (SGA) preterm infants in comparison to appropriate for gestational age (AGA) preterm infants of similar gestational age.MethodWe compared neonatal outcomes of 1336, 1:1 matched, singleton SGA and AGA preterm infants based on their gestational age using data from the study ‘Causes of Illness and Death of Preterm Infants in Ethiopia (SIP)’. Data were analysed using SPSS V.23. ORs and 95% CIs and χ2 tests were done, p value of <0.05 was considered statistically significant.ResultThe majority of the infants (1194, 89%) were moderate to late preterm (32–36 weeks of gestation), 763 (57%) were females. Male preterm infants had higher risk of being SGA than female infants (p<0.001). SGA infants had increased risk of hypoglycaemic (OR and 95% CI 1.6 (1.2 to 2.0), necrotising enterocolitis (NEC) 2.3 (1.2 to 4.1), polycythaemia 3.0 (1.6 to 5.4), late-onset neonatal sepsis (LOS) 3.6 (1.1 to 10.9)) and prolonged hospitalisation 2.9 (2.0 to 4.2). The rates of respiratory distress syndrome (RDS), apnoea and mortality were similar in the SGA and AGA groups.ConclusionNeonatal complications such as hypoglycaemic, NEC, LOS, polycythaemia and prolonged hospitalisation are more common in SGA infants, while rates of RDS and mortality are similar in SGA and AGA groups. Early recognition of SGA status, high index of suspicion and screening for complications associated and timely intervention to prevent complications need due consideration.

Abstract Background Offspring of women with type 1 diabetes are at increased risk of accelerated fetal growth which is associated with perinatal morbidity. Growth standards are used to identify large- or small- for gestational age (LGA, SGA) infants. Our aim was to examine which growth standards identify infants at risk of perinatal complications during the Continuous Glucose Monitoring in Type 1 Diabetes Pregnancy Trial (CONCEPTT). Methods This was a pre-specified analysis of CONCEPTT involving 225 pregnant women from 31 international centres. Infants were weighed immediately at birth and GROW, INTERGROWTH and WHO centiles calculated. Unadjusted logistic regression identified the associations between different growth standards and perinatal outcomes including preterm delivery, Caesarean delivery, neonatal hypoglycaemia, hyperbilirubinaemia, respiratory distress, neonatal intensive care unit (NICU) admission and a composite neonatal outcome. Results Accelerated fetal growth was common, with mean birthweight percentiles of 82.1, 85.7 and 63.9 and LGA rates of 62%, 67% and 30% using GROW, INTERGROWTH and WHO standards respectively. Corresponding rates of SGA were 2.2%, 1.3% and 8.9% respectively. All standards were associated with some but not all perinatal outcomes studied. Infants born >97.7 th centile were at highest risk of complications. Conclusions WHO standards underestimated birthweight centile. GROW and INTERGROWTH standards identified similar numbers of infants as LGA and SGA with GROW showing stronger associations with neonatal hypoglycaemia, hyperbilirubinaemia and NICU admission. Infants with suspected birthweight >97.7th centile according to any standard may require extra surveillance. Definitions of LGA and SGA should be re-evaluated in diabetic pregnancy.

Abstract Background Offspring of women with type 1 diabetes are at increased risk of fetal growth patterns which are associated with perinatal morbidity. Our aim was to compare rates of large- and small-for-gestational age (LGA; SGA) defined according to different criteria, using data from the Continuous Glucose Monitoring in Type 1 Diabetes Pregnancy Trial (CONCEPTT).Methods This was a pre-specified analysis of CONCEPTT involving 225 pregnant women and liveborn infants from 31 international centres. Infants were weighed immediately at birth and GROW, INTERGROWTH and WHO centiles were calculated. Relative risk ratios, sensitivity and specificity were used to assess the different growth standards with respect to perinatal outcomes, including neonatal hypoglycaemia, hyperbilirubinaemia, respiratory distress, neonatal intensive care unit (NICU) admission and a composite neonatal outcome. Results Accelerated fetal growth was common, with mean birthweight percentiles of 82.1, 85.7 and 63.9 and LGA rates of 62%, 67% and 30% using GROW, INTERGROWTH and WHO standards respectively. Corresponding rates of SGA were 2.2%, 1.3% and 8.9% respectively. LGA defined according to GROW centiles showed stronger associations with preterm delivery, neonatal hypoglycaemia, hyperbilirubinaemia and NICU admission. Infants born >97.7th centile were at highest risk of complications. SGA defined according to INTERGROWTH centiles showed slightly stronger associations with perinatal outcomes. Conclusions GROW and INTERGROWTH standards performed similarly and identified similar numbers of neonates with LGA and SGA. GROW-defined LGA and INTERGROWTH-defined SGA had slightly stronger associations with neonatal complications. WHO standards underestimated size in preterm infants and are less applicable for use in type 1 diabetes.Trial registration: This trial is registered with ClinicalTrials.gov. number NCT01788527.

Abstract Objectives To compare cardiac structural and functional findings of fetuses with fetal growth restriction (FGR) and small for gestational age (SGA). Methods In this prospective cohort study, patients were classified into three groups using Delphi procedure according to fetal weight, umbilical, uterine artery Doppler and cerebroplacental ratio. Fetal cardiac ultrasonographic morphology and Doppler examination was performed to all pregnant women at 36 weeks of gestation. Results Seventy three patients were included in the study. There were one (6.7%) patient in the control group, 2 (13.3%) in the SGA group and 12 (80%) in the FGR group who needed neonatal intensive care unit (NICU) and NICU requirement was significantly higher in FGR fetuses (p<0.001). Left spherical index was found to be lower only among FGR fetuses (p=0.046). Left ventricular wall thickness was decreased and the right/left ventricular wall ratio was increased in FGR fetuses (p=0.006, p<0.001). Tricuspid/mitral valve ratio and mitral annular plane systolic excursion value was lower in FGR fetuses (p=0.034, p=0.024 respectively). Also, myocardial performance index was remarkably higher in FGR group (p=0.002). Conclusions We detected cardiac morphological changes in cases of both SGA and FGR—more pronounced in the FGR cases. Findings related to morphological changes on the left side in FGR cases were considered secondary to volume increase in FGR cases as an indicator of a brain-protective effect. In the FGR group, both systolic and diastolic dysfunctions were detected in the left heart.

Objective Small-for-gestational age infants are at an increased risk for disabilities and chronic health problems. Smoking and hypertension during pregnancy pose significant risks for fetal growth restriction. The study aims to identify whether (1) the timing of tobacco use modifies the risk of small-for-gestational age, (2) there are differences in association by percentile of small-for-gestational age (3rd, 5th, and 10th percentile), and (3) the effect of tobacco exposure on small-for-gestational age outcome is mediated by hypertension. Materials and Methods Data were obtained from the 2009 Natality public use file available through the National Center for Health Statistics. Women were categorized into 11 groups depending on the trimester of tobacco exposure, the number of daily cigarettes smoked, and presence of hypertension. Multivariable log-linear regression models were performed to determine the association between percentile of singleton small-for-gestational age outcome (3rd, 5th, and 10th), trimester and degree of tobacco exposure, and hypertension. Results Hypertension and smoking worked synergistically to restrict fetal growth. Hypertensive women who smoked heavily in all three trimesters were 4.34 times more likely to give birth to a 3rd percentile small-for-gestational age infant compared with nonsmoking normotensive women. Conclusion The timing and duration of tobacco exposure mediates the risk and severity of fetal growth restriction.
