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.

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.

ABSTRACT Objective This study was done to assess the Doppler cerebroplacental ratio (CPR) in the prediction of adverse perinatal outcome especially in growth restricted pregnancies. Materials and methods In this study, 62 antenatal women were subjected to Doppler studies at 34 to 42 weeks of gestations. CPR was calculated and less than 1 was taken as predictor of adverse perinatal outcome. Adverse perinatal outcomes was evaluated by mode of delivery, meconium staining, 1 and 5-minute Apgar scores, birth weight, admission to NICU and other neonatal complications. Results Of 62 antenatal women, with an abnormal CPR had higher incidence of meconium, clinical fetal distress, operative delivery, low Apgar score (5 mins), NICU admission and neonatal death, 42.88, 47.62, 26.57, 76.19, 66.17 and 66.67% respectively as compared to women with normal CPR who had 4.88, 2.88, 2.88. 2.88, 12.19, 17.07 and 0% respectively. With the use of an abnormal CPR, the sensitivity, specificity, and positive and negative predictive values for predicting an adverse outcome were 62, 80, 62 and 80%, respectively, with an odds ratio (95% confidence interval). Conclusion An abnormal CPR is associated with adverse perinatal outcomes, especially in growth-restricted fetuses. How to cite this article Shaheen S, Bano I, Ahmad I, Singh A.

IntroductionFetal growth restriction (FGR) is a serious pregnancy complication, associated with increased rates of perinatal death and morbidity among survivors. Most commonly FGR results from placental insufficiency, where the placenta fails to deliver the oxygen and nutrients required for normal fetal growth. This leads to fetal oxidative stress, resulting in organ damage through lipid peroxidation. The early developing brain is particularly susceptible, such that FGR is associated with poorer neurodevelopment, witnessed as cognitive and behavioural dysfunction, and cerebral palsy. Promisingly, melatonin, a lipid soluble antioxidant is neuroprotective in animal models of FGR. We present a protocol outlining a randomised, placebo-controlled trial to explore whether antenatal maternal melatonin supplementation in pregnancies with severe, early-onset FGR can improve neurodevelopment among survivors at 2 years of age.Methods and analysesWe will recruit 336 women with a singleton pregnancy complicated by FGR between 23+0 and 31+6 weeks gestation. Participants will be randomised, stratified by gestational age, to either 30 mg melatonin per day or a visually identical placebo, continued until birth. Measures of maternal and fetal health will be collected until birth. Timing of birth will be determined by the treating clinical team in discussion with the woman. Neonatal and infant neurodevelopmental assessments will be undertaken, consisting of brain MRI at term corrected age, general movements assessment at term and 3 months’ corrected age, and Bayley Scales of Infant & Toddler Development-III and Infant Toddler Social Emotional Assessment at 2.5 years corrected age. Analyses will be on intention to treat. The primary outcome is a difference of 5 points in the cognitive domain of the Bayley-III. Secondary outcomes address maternal and fetal safety.Ethics and disseminationThis trial has Monash Health Human Research and Ethics committee approval (17-0000-583A). Findings will be disseminated through peer-reviewed publications, conference presentations and to participants.Trial registration numberACTRN12617001515381; Pre-results

Background: Fetal Growth Restriction (FGR) is the single largest contributing factor to perinatal morbidity in non-anomalous foetuses. Synonymous with Intrauterine Growth Restriction (IUGR), it is defined as an estimated fetal weight less than the10th percentile. Obstetric Doppler has helped in early detection and timely intervention in babies with FGR with significant improvements in perinatal outcomes.  Hence, authors evaluated the maternal risk factors and diagnosis-delivery intervals and perinatal outcomes in FGR using Doppler.Methods: This research conducted in a tertiary care hospital in South Kerala included 82 pregnant women who gave birth to neonates with birth weight less than the 10th percentile over a period of1 year (Jan 1, 2017-Dec 31, 2017). Socio-demographic, maternal risk, Diagnosis- delivery interval in FGR and neonatal morbidities were studied.Results: Mean GA at diagnosis in weeks was 34.29 and 35.19 respectively for abnormal and normal Doppler respectively (p value-0.032). The mean birthweight in Doppler abnormal FGR was 272.34 g lesser than in Doppler normal group (p value-0.001). Growth restricted low birth weight neonates had Doppler   pattern abnormalities (p value-0.0009). FGR <3rd percentile and AFI <5 had abnormal Doppler (OR:6.7). Abnormal biophysical profile (OR:14) and Non-Reactive NST (OR:3.5) correlated with abnormal Doppler. Growth restricted with normal Doppler had shorter NICU stays than with abnormalities (p value-0.003). Term FGR went home early than early preterm. (p value-0.001).Conclusions: Abnormal Doppler velocimetry is significantly associated with earlier FGR detection, shorter decision- delivery interval, reduction in the mean birthweight and longer NICU stay. Hence, Umbilical artery Doppler and Cerebroplacental index is an integral part of in-utero fetal surveillance to identify impending fetal hypoxia, appropriate management, optimising the timing of delivery and improve perinatal health in FGR.
