INTRODUCTION: A vasa previa (VP) refers to aberrant chorionic vessels which can either connect the chorionic plate to a velamentous cord (type I) or a succenturiate or accessory lobe to the main placental mass (type II). METHODS: We performed retrospective cohort study of 32 singleton pregnancies diagnosed with VP. The levels of maternal serum alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) were measured at 15-18 weeks as part of the triple test screening for Trisomy 21...

PROBLEM: Immune tolerance with respect to a semi-allogeneic fetus plays a key role in the establishment of a pregnancy. Memory T follicular helper (Tfh) cells have a central role in the regulation of the adaptive immune response. Much of our knowledge of memory Tfh cells' function comes from immune-related diseases. However, the true physiological characteristics of memory Tfh cells and their mode of action in pregnancy remain unclear. METHODS OF STUDY: Deciduas and blood were obtained from 25 recurrent spontaneous abortion (RSA) patients undergoing surgical abortion and 19 normal women in early pregnancy undergoing elective termination...

OBJECTIVE: In patients with pre-gestational and gestational diabetes mellitus (GDM), insulin requirements often increase during the third trimester of pregnancy in order to maintain proper glycemic control. However, a fraction of patients demonstrate a significant decrease in insulin requirements in late gestation. We aimed to evaluate the clinical significance of decreasing insulin requirements in patients with pre-gestational diabetes and GDM with respect to fetal wellbeing and pregnancy outcome...

Adequate placental angiogenesis is critical for the establishment of the placental circulation and thus for normal feto-placental growth and development. Fatty acid-binding protein-4 (FABP4) plays a pro-angiogenic role in endothelial cells; however, very little information is available in placental first trimester trophoblast cells. Here we report that exogenously added FABP4 (exo-FABP4) stimulated tube formation (as a measure of in vitro angiogenesis) in HTR8/SVneo trophoblastic cells. HTR-8/SVneo cells were incubated in the presence of exogenously added FABP4 at different concentrations and time points...

BACKGROUND: Many stillbirths of normally-formed fetuses in the third trimester could be prevented via delivery if reliable means to anticipate this outcome existed. However, since the etiology of these stillbirths is often unexplained and, although the underlying mechanism is presumed to be hypoxia from "placental insufficiency", the placentas often appear normal on histopathologic examination. Gestational age is a risk factor for antepartum stillbirth, with a rapid rise in stillbirth rates after 40 weeks gestation...

BACKGROUND/AIM: Recurrent pregnancy loss (RPL) is defined as two or more pregnancy losses. T-regulatory cells play an important role in the feto-maternal interface. Cytotoxic-T-lymphocyte antigen-4 (CTLA-4) is a molecule that downregulates the activation and proliferation of T cells. The objective of the current study was to investigate the possible association of CTLA-4+49A/G gene polymorphism with RPL among patients from the Iranian Azeri Turkish ethnic group. MATERIALS AND METHODS: The study group/patients consisted of 101 women with the experience of two or more pregnancy losses and the control group consisted of 101 women with at least two live births, without any previous history of pregnancy loss and autoimmune diseases from the same ethnic group...

PURPOSE: Feto-placental unit represents an important source of activin A, a member of transforming growth factors-β involved in the mechanisms of labor. No evidences are available on activin A in pregnancies beyond 41 weeks of gestation, where induction of labor is often required. The present study aimed to evaluate activin A maternal serum levels and placental mRNA expression in term and late-term pregnancy, with spontaneous or induced labor, and its possible role to predict the response to labor induction...

Stress during pregnancy is associated with metabolic dysfunction in the adult offspring in human and other animals. However, little is known about the metabolic effects of pregnancy stress on the mothers and fetuses during pregnancy itself. This study aimed to determine the consequences of the common experimental procedures of injection and single housing in pregnant rats on fetal and maternal hepatic glucogenic capacities. On day (D) 20 of pregnancy, feto-placental weights and the glycogen content and activities of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) of fetal and maternal liver were measured in rats pair or single housed from D1 with or without saline injection from D15 to D19...

Neonatal lupus erythematosus is an autoimmune disease resulting from the trans-placental passage of maternal anti-SSA/Ro, anti-SSB/La, and less frequently anti-RNP antibodies to the foetus. At the time of diagnosis 50% of mothers are asymptomatic. Neonatal manifestations of this multisystem disease may include congenital heart block, cutaneous lesions and haematological abnormalities. We present the case of congenital neonatal lupus erythematosus in non-identical twins, showing variability in clinical manifestation of this disease,despite receiving the same level of antibodies from the mother...

The placental labyrinth is the interface for gas and nutrient exchange between the embryo and the mother; hence its proper development is essential for embryogenesis. However, the molecular mechanism underlying development of the placental labyrinth, particularly in terms of its endothelial organization, is not well understood. Here, we determined that fibronectin leucine-rich transmembrane protein 2 (FLRT2), a repulsive ligand of the UNC5 receptor family for neurons, is unexpectedly expressed in endothelial cells specifically in the placental labyrinth...

Malaria during pregnancy can cause various feto-maternal complications. Life threatening respiratory involvement is rare with vivax malaria but common with Plasmodium falciparum. In most of the cases severe respiratory involvement occurs, after beginning of anti-malarial treatment. We are reporting a case which involved a diagnostic and therapeutic challenge, as the pregnant woman with severe preeclampsia developed acute respiratory distress, actually caused by Plasmodium vivax.

Cardiac etiologies of hydrops fetalis have been a topic of concern due to challenging perinatal management. The common cardiac etiologies leading to hydrops fetalis include structural cardiac anomalies, cardiac dysrhythmias, cardiac tumors, cardiomyopathy and myocarditis. The mechanisms of cardiogenic hydrops fetalis may be: 1) elevation of atrial pressure and volume overload, 2) decrease of cardiac output, and 3) development of congestive heart failure. The diagnosis of hydrops fetalis was usually made at 19-36 gestational weeks, when ultrasound is a highly effective diagnostic method...

There is clear evidence that nutritional strategy employed during pregnancy has profound influence on the offspring health outcomes. However, the effect of the quality and the quantity of maternal fat intake on maternal metabolic profile during different stages of pregnancy and its impact on pregnancy sustainability is not known. Female C57BL/6 mice (7 weeks old) were fed diets varying in the quantity of fat (5% vs 11%) for two weeks prior to mating and throughout pregnancy. The 5% fat diet was enriched with longer chain omega (n)-3 polyunsaturated fatty acids (PUFA) from fish oil...

Expression and function of the follicle‑stimulating hormone receptor (FSHR) are traditionally thought to be limited to the ovary in females. However, recent studies have indicated that the FSHR is also expressed in endothelial cells of the placental vasculature, and that the haploinsufficiency of the feto‑placental FSHR impaired the growth of the mouse placenta. The aim of the current study was to investigate the placental expression of FSH and FSHR in pregnancies complicated by pre‑eclampsia. Placental tissue samples were collected from 20 pregnancies with pre‑eclampsia and 25 normal pregnancies...
