Simple Definition

Selective fetal growth restriction (sFGR) has been reported to occur in about 10–15% of monochorionic (MC) twins. The diagnosis of sFGR has been based on variable criteria including estimated fetal weight (EFW), abdominal circumference and/or the degree of fetal weight discordance. Recent studies tend to use a simple definition which includes the presence of an EFW less than the 10th percentile in the smaller twin. Some would argue that the intertwin fetal weight discordance should be included in the definition. Indeed this factor plays a major role in the complications presented by these cases. While the majority of cases with one fetus below the 10th percentile usually will also present with a large intertwin EFW discordance, the contrary is not always true. Thus, it is possible to find MC twins with remarkable intertwin EFW discordance but the EFW of both fetuses are still within normal ranges. Although it appears to be common sense that a large intertwin discrepancy might represent a higher risk for some of the complications described later in this review, there is no consistent evidence to support this notion. Therefore, due to its simplicity, a definition based on an EFW below 10th percentile in one twin is probably the most useful for clinical and research purposes.

Abstract Background Prediction models for early and late fetal growth restriction (FGR) have been established in many high-income countries. However, prediction models for late FGR in China are limited. This study aimed to develop a simple combined first- and second-trimester prediction model for screening late-onset FGR in South Chinese infants.Methods This retrospective study included 2258 women who had singleton pregnancies and received routine ultrasound scans. Late-onset FGR was defined as a birth weight < the 10th percentile plus abnormal Doppler indices and/or a birth weight below the 3rd percentile after 32 weeks, regardless of the Doppler status. Multivariate logistic regression was used to develop a prediction model.Results Ninety-three fetuses were identified as late-onset FGR. The significant predictors for late-onset FGR were maternal age, height, weight, and medical history; the second-trimester head circumference (HC)/abdominal circumference (AC) ratio; and the estimated fetal weight (EFW). This model achieved a detection rate (DR) of 52.6% for late-onset FGR at a 10% false positive rate (FPR) (area under the curve (AUC): 0.80, 95%CI 0.76-0.85).Conclusions A multivariate model combining first- and second-trimester default tests can detect 52.6% of cases of late-onset FGR. Further studies with more screening markers are needed to improve the detection rate.

Histopathological Lesions

Ultrafine particles (UFPs) are particles smaller than 100 nanometers that are produced unintentionally during human activities or natural phenomena. They have a higher biological reactivity than bigger particles and can reach the placenta after maternal exposure. One study has shown an association between maternal occupational exposure to UFPs and fetal growth restriction. Yet few studies have focused on the effects of UFP exposure on placental histopathological lesions. The aim of this study was to investigate the association between maternal occupational exposure to UFPs and histopathological lesions of their placenta. The analyses were based on data from the ARTEMIS Center. A job-exposure matrix was used to assess occupational exposure to UFPs. The histopathological placental exam was performed by two pathologists who were blinded to the exposure of each subject. The examination was conducted in accordance with the recommendations of the Amsterdam consensus. The study sample included 130 placentas (30 exposed, 100 unexposed). Maternal occupational exposure to UFPs during pregnancy is significantly associated with placental hypoplasia (the phenomenon affected 61% of the exposed patients and 34% of the unexposed ones, p < 0.01). Further research is needed to explain its pathophysiological mechanisms.

New Criteria

Abstract Background: Preeclampsia (PE) is a hypertensive disorder specific to pregnancy, which sometimes causes severe maternal-neonatal complications. The International Society for the Study of Hypertension in Pregnancy revised their criteria for PE in 2018; a PE diagnosis can be established in the absence of proteinuria when other specific symptoms exist, such as other organ dysfunction or uteroplacental dysfunction. Therefore, the initial findings of PE (IFsPE) at the first diagnosis can vary considerably across patients. However, there are no reports on patients with PE based on different IFsPE and their impact on patients’ clinical outcomes. Thus, we aimed to investigate the predictors of maternal and neonatal outcomes based on IFsPE according to the new criteria.Methods: This was a retrospective study involving 3729 women who delivered at our hospital between 2015 and 2019. All women were reclassified based on the new criteria. They were divided into three groups based on the IFsPE: Classification 1 (C-1), proteinuria (classical criteria); Classification 2 (C-2), damage to other maternal organs; and Classification 3 (C-3), uteroplacental dysfunction. Maternal and fetal conditions and perinatal outcomes were assessed in the three groups.Results: In total, 104 women with PE were included. Of those, 42 (40.4%), 28 (26.9%), and 34 (32.7%) were assigned to C-1, C-2, and C-3 groups, respectively. All women in C-3 showed fetal growth restriction (FGR). The number of gestational weeks at PE diagnosis and delivery was significantly lower in the C-3 group (C-1, 35.5±3.0 weeks; C-2, 35.2±3.6 weeks; C-3, 31.6±4.6 weeks, P < 0.01; and C-1, 36.8±2.8 weeks; C-2, 36.3±3.2 weeks; C-3, 33.4±4.4 weeks, P < 0.01, respectively). The rates of preterm delivery at < 34 weeks (odds ratio [OR]=4.58 [1.74-12.10] and OR=2.83 [1.01-7.97]), cesarean delivery (OR=4.35 [1.41-13.45] and OR=5.03 [1.51-16.78]), Apgar scores < 7 at 1 min (OR=6.58 [2.08-20.80] and OR=4.09 [1.26-13.29]), neonatal intensive care unit admission (OR=12.19 [3.62-41.08], OR=7.50 [2.09-26.96]), and composite neonatal complications (OR=6.58 [2.08-20.80] and OR=5.33 [1.52-18.70]) were significantly higher in the C-3 group than in the C-1 and C-2 groups.Conclusions: PE patients with FGR had the most unfavorable prognosis for both maternal and neonatal outcomes.
