Background: Infections, as well as adverse birth outcomes, may be more frequent in migrant women. Schistosomiasis, echinococcosis, and hepatitis E virus (HEV) seropositivity are associated with the adverse pregnancy outcomes of fetal growth restriction and premature delivery. Methods: A cohort study of 82 pregnant women with a history of migration and corresponding delivery of newborns in Germany was conducted. Results: Overall, 9% of sera tested positive for anti-HEV IgG. None of the patients tested positive for anti-HEV IgM, schistosomiasis, or echinococcus serology. Birth weights were below the 10th percentile for gestational age in 8.5% of the neonates. No association between HEV serology and fetal growth restriction (FGR) frequency was found. Conclusions: In comparison to German baseline data, no increased risk for HEV exposure or serological signs of exposure against schistosomiasis or echinococcosis could be observed in pregnant migrants. An influence of the anti-HEV serology status on fetal growth restriction could not be found.

Adverse Pregnancy

Fetal growth restriction (FGR) is an adverse pregnancy outcome associated with significant perinatal and paediatric morbidity and mortality, and an increased risk of chronic disease later in adult life. One of the key causes of adverse pregnancy outcome is fetal growth restriction (FGR). While a number of maternal, fetal, and environmental factors are known causes of FGR, the majority of FGR cases remain idiopathic. These idiopathic FGR pregnancies are frequently associated with placental insufficiency, possibly as a result of placental maldevelopment. Understanding the molecular mechanisms of abnormal placental development in idiopathic FGR is, therefore, of increasing importance. Here, we review our understanding of transcriptional control of normal placental development and abnormal placental development associated with human idiopathic FGR. We also assess the potential for understanding transcriptional control as a means for revealing new molecular targets for the detection, diagnosis, and clinical management of idiopathic FGR.

SummaryIt was the objective of this study to analyse the influence of confounders, such as ethnicity, severity of illness and method of testing, in articles concerning the still moot relationship of thrombophilias to adverse pregnancy outcome (APO). Relevant casecontrol studies were identified using Medline and EMBASE databases between 1966 and 2006. Search terms were recurrent fetal loss, intrauterine fetal death, preeclampsia, HELLP-syndrome, eclampsia, fetal growth restriction, abruptio placentae, combined with maternal thrombophilias. Data was extracted from the articles per subgroup ofAPO regardless of confounder. These subgroups were tested if they fulfilled the heterogeneity testing criterion (I2 > 35%) to weigh the influence of the confounder. Confounders were selected and examined with Mantel- Haenszel method. Increased thrombophilia prevalence was confirmed in most adverse pregnancy outcomes. Ethnicity, genetic testing only and severity of illness were confounders in the various forms of APO. Stronger relationships between factor V Leiden and severity of disease were found in 2nd and 3rd trimester than 1st trimester recurrent fetal loss, in preeclampsia with: blood pressure ≥160/110 mmHg than ≥140/90 mmHg; proteinuria ≥5 grams per day than < 5 grams; onset before than after 28 weeks, in fetal growth restriction <3rd percentile than <5th, than <10th, and in earlier occurrence of abruptio placentae than 3rd trimester. In conclusion, reports on the prevalence of maternal thrombophilias and APO are influenced by various confounders, which are not always appropriately analysed. The differences we have identified reflect the differential impact of these confounders. These data emphasise the importance of more uniform research.

Language Literature

Fetal growth restriction (FGR) refers to pregnancy complications associated with an increased risk of perinatal morbidity and mortality and is defined in the Russian-language literature as the fetal size and weight retardation in relation to the norm for a given gestational age, and in the English-language literature – as the inability of the fetus to realize its genetically determined growth potential. FGR is the cause of 43% of stillbirths of unspecified etiology, and some cases remain undiagnosed even in high-risk populations due to the lack of universal diagnostic standards for this pathology. The review presents a critical analysis of the existing definitions of FGR, the latest data on risk factors, an assessment of diagnostic methods for its early and late forms, the prospects of using biomarkers and instrumental methods of examination in predicting adverse perinatal outcomes, and an algorithm for the management of pregnancy complicated by FGR. For a more complete coverage of the literature and deeper understanding of the nosology, attention is focused on FGR that is not accompanied by preeclampsia and other hypertensive disorders, which occur in about 30% of cases.

Adverse Pregnancy

Oxidative stress is caused by an imbalance between the production of reactive oxygen species (ROS) in cells and tissues and the ability of a biological system to detoxify them. During a normal pregnancy, oxidative stress increases the normal systemic inflammatory response and is usually well-controlled by the balanced body mechanism of the detoxification of anti-oxidative products. However, pregnancy is also a condition in which this adaptation and balance can be easily disrupted. Excessive ROS is detrimental and associated with many pregnancy complications, such as preeclampsia (PE), fetal growth restriction (FGR), gestational diabetes mellitus (GDM), and preterm birth (PTB), by damaging placentation. The placenta is a tissue rich in mitochondria that produces the majority of ROS, so it is important to maintain normal placental function and properly develop its vascular network to ensure a safe and healthy pregnancy. Antioxidants may ameliorate these diseases, and related research is progressing. This review aimed to determine the association between oxidative stress and adverse pregnancy outcomes, especially PE, FGR, GDM, and PTB, and explore how to overcome this oxidative stress in these unfavorable conditions.

Fetal growth restriction is an important pregnancy complication that has major consequences for the fetus and neonate as well as an increased risk of long-term morbidity extending into adulthood. The precise aetiology of most cases of fetal growth restriction is unknown although placental thrombosis is a common feature in many of these cases. This paper will outline the potential role of proteoglycans in contributing to placental thrombosis and fetal growth restriction.

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.
