Current tests available to diagnose fetal hypoxia in-utero lack sensitivity thus failing to identify many fetuses at risk. Emerging evidence suggests that microRNAs derived from the placenta circulate in the maternal blood during pregnancy and may be used as non-invasive biomarkers for pregnancy complications. With the intent to identify putative markers of fetal growth restriction (FGR) and new therapeutic druggable targets, we examined, in maternal blood samples, the expression of a group of microRNAs, known to be regulated by hypoxia. The expression of microRNAs was evaluated in maternal plasma samples collected from (1) women carrying a preterm FGR fetus (FGR group) or (2) women with an appropriately grown fetus matched at the same gestational age (Control group). To discriminate between early- and late-onset FGR, the study population was divided into two subgroups according to the gestational age at delivery. Four microRNAs were identified as possible candidates for the diagnosis of FGR: miR-16-5p, miR-103-3p, miR-107-3p, and miR-27b-3p. All four selected miRNAs, measured by RT-PCR, resulted upregulated in FGR blood samples before the 32nd week of gestation. By contrast, miRNA103-3p and miRNA107-3p, analyzed between the 32nd and 37th week of gestation, showed lower expression in the FGR group compared to aged matched controls. Our results showed that measurement of miRNAs in maternal blood may form the basis for a future diagnostic test to determine the degree of fetal hypoxia in FGR, thus allowing the start of appropriate therapeutic interventions to alleviate the burden of this disease.

Abstract Objective To evaluate the association between early-onset fetal growth restriction (FGR), late-onset FGR, small for gestational age (SGA) and adequate for gestational age (AGA) fetuses and adverse perinatal outcomes. Methods This was a retrospective longitudinal study in which 4 groups were evaluated: 1 — early-onset FGR (before 32 weeks) (n = 20), 2 — late-onset FGR (at or after 32 weeks) (n = 113), 3 — SGA (n = 59), 4 — AGA (n = 476). The Kaplan-Meier curve was used to compare the time from the diagnosis of FGR to birth. Logistic regression was used to determine the best predictors of adverse perinatal outcomes in fetuses with FGR and SGA. Results A longer time between the diagnosis and birth was observed for AGA than for late FGR fetuses (p < 0.001). The model including the type of FGR and the gestational age at birth was significant in predicting the risk of hospitalization in the neonatal intensive care unit (ICU) (p < 0.001). The model including only the type of FGR predicted the risk of needing neonatal resuscitation (p < 0.001), of respiratory distress (p < 0.001), and of birth at < 32, 34, and 37 weeks of gestation, respectively (p < 0.001). Conclusion Fetal growth restriction and SGA were associated with adverse perinatal outcomes. The type of FGR at the moment of diagnosis was an independent variable to predict respiratory distress and the need for neonatal resuscitation. The model including both the type of FGR and the gestational age at birth predicted the risk of needing neonatal ICU hospitalization.

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.

AbstractBackgroundAs conflicting results have been reported about the association of reversed flow on the aortic isthmus (AoI) and adverse perinatal results in fetal growth restriction (FGR), we aim to compare perinatal outcomes (including tolerance to labor induction) of late-onset FGR between those with anterograde and reversed AoI flow.MethodsThis was an observational retrospective cohort study on 148 singleton gestations diagnosed with late-onset FGR (diagnosis ≥32+0 weeks), with an estimated fetal weight (EFW) <10thcentile and mild fetal Doppler alteration: umbilical artery (UA) pulsatility index (PI) >95thcentile, middle cerebral artery (MCA)-PI <5thcentile or cerebral-placental ratio <5thcentile. Anterograde AoI flow was present in n=79 and reversed AoI flow in n=69. Delivery was recommended from 37 weeks in both groups. Perinatal results were compared between the groups.ResultsThe global percentage of vaginal delivery of fetuses with anterograde and reversed blood flow was 55.7% vs. 66.7% (P=0.18) and the percentage of cesarean section (C-section) for non-reassuring fetal status was 12.7% vs. 15.9% (P=0.29), respectively. When evaluating those that underwent labor induction, the vaginal delivery rate was 67.9% vs. 77.2% (P=0.17), respectively. There were no significant differences regarding any other perinatal variables and there were no cases of severe morbidity or mortality.ConclusionWe observed that the presence of reversed AoI flow does not worsen perinatal outcomes on fetuses with late-onset growth restriction with mild Doppler alterations. Attempt of labor induction is feasible in these fetuses regardless of the direction of AoI flow.

AbstractObjectivesLate-onset fetal growth restriction (FGR) has heterogeneous prenatal and postnatal diagnostic criteria. We compared the prenatal and postnatal diagnosis of late-onset FGR and their ability to predict adverse perinatal outcomes.MethodsRetrospective cohort study of 5442 consecutive singleton pregnancies that delivered beyond 34 + 0 weeks. Prenatal diagnosis of FGR was based on customized fetal growth standards and fetal Doppler while postnatal diagnosis was based on a birthweight <3rd percentile according to newborn charts (Olsen’s charts and Intergrowth 21st century programme). Perinatal outcomes were analyzed depending on whether the diagnosis was prenatal, postnatal or both.ResultsA total of 94 out of 5442 (1.7%) were diagnosed as late-onset FGR prenatally. Olsen’s chart and Intergrowth 21st chart detected that 125/5442 (2.3%) and 106/5442 (2.0%) of infants had a birthweight <3rd percentile, respectively. These charts identified 35/94 (37.2%) and 40/94 (42.6%) of the newborns with a prenatal diagnosis of late-onset FGR. Prenatally diagnosed late-onset FGR infants were at a higher risk for hypoglycemia, jaundice and polycythemia. Both prenatally and postnatally diagnosed as late-onset FGR had a higher risk for respiratory distress syndrome when compared to non-FGR. The higher risks for intensive care admission and composite adverse outcomes were observed in those with a prenatal diagnosis of late-onset FGR that was confirmed after birth.ConclusionsCurrent definitions of pre- and postnatal late-onset FGR do not match in more than half of cases. Infants with a prenatal or postnatal diagnosis of this condition have an increased risk of neonatal morbidity even if these diagnoses are not coincident.
