The objective of the study was to identify the profile of circulating C19MC microRNAs (miR-516-5p, miR-517*, miR-518b, miR-520a*, miR-520h, miR-525, and miR-526a) in patients with established preeclampsia (n=63), fetal growth restriction (n=27), and gestational hypertension (n=23). We examined the correlation between plasmatic concentrations and expression levels of microRNAs and the severity of the disease with respect to clinical signs, requirements for the delivery, and Doppler ultrasound parameters. Using absolute and relative quantification approaches, increased extracellular C19MC microRNA levels (miR-516-5p,P=0.037,P=0.009; miR-517*,P=0.033,P=0.043; miR-520a*,P=0.001,P=0.009; miR-525,P=0.026,P=0.01; miR-526a,P=0.03,P=0.035) were detected in patients with preeclampsia. The association analysis pointed to no relationship between C19MC microRNA plasmatic concentrations and expression profile and identified risk factors for a poorer perinatal outcome. However, the dependence between the levels of plasmatic C19MC microRNAs and the pulsatility index in the middle cerebral artery and the values of cerebroplacental ratio was demonstrated. The study brought the interesting finding that the upregulation of miR-516-5p, miR-517*, miR-520a*, miR-525, and miR-526a is a characteristic phenomenon of established preeclampsia.

Introduction: Hypertensive Disorders in Pregnancy (HDP), is a common complication of pregnancy leading to majority of adverse perinatal outcome. The timely diagnosis of fetal compromise, before irreversible damage, is possible by doing Cerebroplacental Ratio (CPR), on doppler ultrasonography. CPR is calculated as ratio of Pulsatility Index (PI) of Middle cerebral Artery and Umblical Artery (UA). It reflects both the circulatory insufficiency in UA along with adaptive changes in Middle cerebral Artery (MCA). Aim: To evaluate role of Cerebroplacental Ratio as predictor of Fetal Growth Restriction and perinatal outcome in singleton pregnancy with HDP at 28-41 weeks of gestation. Materials and Methods: A prospective observational cohort study was carried out in the Department of Obstetrics and Gynaecology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India. The study included 150 women with singleton pregnancy, HDP and 28-41 weeks of gestation. Doppler ultrasound was performed and CPR calculated as ratio of MCA PI and UA PI, using ultrasound study performed within two weeks of delivery. All women were followed-up till delivery and perinatal outcome i.e., birth weight, preterm birth, cesarean for fetal distress, Meconium Stained Liquor (MSL) , APGAR at 5 minutes, still birth, Neonatal Intensive Care Unit (NICU) admission and early neonatal death, were recorded. The data entry was done in the Microsoft excel spreadsheet and the final analysis was done with the use of Statistical Package for Social Sciences (SPSS) software version 21.0. Results: Out of 150 women, 20% (30) had abnormal CPR. Abnormal CPR had significant association with Low Birth Weight (LBW) (p-value=0.0001), preterm delivery (p-value=0.0001), fetal distress (p-value=0.0001), caesarean for fetal distress (p-value=0.0001), 5-minute APGAR score <7 (p-value=0.0001), NICU admission (p-value=0.0001), Meconium Stained Liquor (MSL) (p-value=0.0001) and neonatal death (p-value=0.025). CPR had 100% sensitivity and 100% Negative Predictive Value (NPV) for predicting adverse perinatal outcome with diagnostic accuracy of 47.33%. Conclusion: The CPR is an independent predictor of Fetal Growth Restriction (FGR) in women with HDP. It can also independently predict perinatal outcome in women with HDP with or without FGR. Abnormal CPR had 100% sensitivity for identifying women with high risk of adverse perinatal outcomes, whereas normal CPR, with NPV of 100%, almost excludes it.

<b><i>Introduction:</i></b> The role of cerebroplacental ratio (CPR) or umbilicocerebral ratio (UCR) to predict adverse intrapartum and perinatal outcomes in pregnancies complicated by late fetal growth restriction (FGR) remains controversial. <b><i>Methods:</i></b> This was a multicenter, retrospective cohort study involving 5 referral centers in Italy and Spain, including singleton pregnancies complicated by late FGR, as defined by Delphi consensus criteria, with a scan 1 week prior to delivery. The primary objective was to compare the diagnostic accuracy of the CPR and UCR for the prediction of a composite adverse outcome, defined as the presence of either an adverse intrapartum outcome (need for operative delivery/cesarean section for suspected fetal distress) or an adverse perinatal outcome (intrauterine death, Apgar score &#x3c;7 at 5 min, arterial pH &#x3c;7.1, base excess of &#x3e;−11 mEq/mL, or neonatal intensive care unit admission). <b><i>Results:</i></b> Median CPR absolute values (1.11 vs. 1.22, <i>p</i> = 0.018) and centiles (3 vs. 4, <i>p</i> = 0.028) were lower in pregnancies with a composite adverse outcome than in those without it. Median UCR absolute values (0.89 vs. 0.82, <i>p</i> = 0.018) and centiles (97 vs. 96, <i>p</i> = 0.028) were higher. However, the area under the curve, 95% confidence interval for predicting the composite adverse outcome showed a poor predictive value: 0.580 (0.512–0.646) for the raw absolute values of CPR and UCR, and 0.575 (0.507–0.642) for CPR and UCR centiles adjusted for gestational age. The use of dichotomized values (CPR &#x3c;1, UCR &#x3e;1 or CPR &#x3c;5th centile, UCR &#x3e;95th centile) did not improve the diagnostic accuracy. <b><i>Conclusion:</i></b> The CPR and UCR measured in the week prior delivery are of low predictive value to assess adverse intrapartum and perinatal outcomes in pregnancies with late FGR.

BACKGROUND: Fetal Growth Restriction (FGR) is the largest contributing factor to perinatal morbidity, mortality and impaired neurodevelopment. This research strives to elucidate the perinatal outcomes of stage based management of fetal growth restriction using Obstetric Doppler and its  association with maternal sociodemographic profile.METHODS: The research was  conducted among 320 antenatal women whose Estimated Fetal weight was  <10th centile. Periodic follow up with Doppler was done and managed as per the stage of FGR. Perinatal outcomes were compiled.RESULTS: The incidence of FGR in T.D Medical College, Alappuzha  was 15.23%. SGA  accounted for 47 %.  The proportion of early and late onset FGR was  10.3%    &   89.7%    respectively.  57.18% of the newborns were admitted to NICU.  The common complications were: Low birth weight – 47.8% ARDS – 21% , Sepsis – 9.6%, Necrotizing enterocolitis – 4%, Hyperbilirubinemia – 4.9%. The incidence of Neonatal death and stillbirth were 1.56% and 0.3% respectively. Mothers who were underweight, inadequate weight gain during pregnancy and short inter pregnancy interval had increased risks. Hypertensive disorders of pregnancy was the commonly associated medical condition. CONCLUSION: Prolongation of pregnancy  even by one day results in 2% increased chances of survival of the newborn. Hence, it becomes imperative to identify the benign forms of FGR  to prevent iatrogenic prematurity. Antenatal women should be screened for risk factors and undergo vigilant antepartum surveillance to bring about favourable perinatal outcome.

Objective: To compare the rates of fetal growth restriction (FGR) in singleton and twin pregnancies using singleton and twin-specific birthweight standards. Methods: The study included liveborn twin and singleton pregnancies between January 2000 and January 2019. Hypertensive disorders of pregnancy (HDP) included gestational hypertension and pre-eclampsia. The study outcomes were FGR or small-for-gestational-age (SGA) at birth as assessed using singleton and twin reference charts. Results: The analysis included 1473 twin and 62,432 singleton pregnancies. In singleton pregnancies the risk of PTB <34 weeks without HDP (OR 2.82, p < 0.001), delivery ≥34 weeks with HDP (OR 2.38, p < 0.001), and PTB <34 weeks with HDP (OR 13.65, p < 0.001) were significantly higher in the pregnancies complicated by FGR compared to those without. When selective fetal growth restriction (sFGR) was assessed using the singleton standard, the risk of PTB <34 weeks without HDP (OR 1.03, p = 0.872), delivery ≥34 weeks with HDP (OR 1.36, p = 0.160) were similar in the pregnancies complicated by sFGR compared to those without, while the risk of PTB <34 weeks with HDP (OR 2.41, p = 0.025) was significantly higher in the pregnancies complicated by sFGR compared to those without. When sFGR was assessed using the twin-specific chart, the risk of PTB <34 weeks without HDP (OR 3.55, p < 0.001), delivery ≥34 weeks with HDP (OR 3.17, p = 0.004), and PTB <34 weeks with HDP (OR 5.69, p < 0.001) were significantly higher in the pregnancies complicated by sFGR compared to those without. The stronger and more consistent association persisted in the subgroup analyses according to chorionicity. The strength of association in dichorionic twin pregnancies resembles that of the singletons more closely and consistently when the FGR was diagnosed using the twin-specific charts. Conclusion: FGR in twin pregnancies has a stronger and more consistent association with HDP and PTB when using twin-specific rather than singleton charts. This study provides further evidence supporting the use of twin-specific charts when assessing fetal growth in twin pregnancies.
