BACKGROUND: Caesarean section is associated with blood loss and maternal morbidity. Excessive blood loss requires transfusion of donor (allogeneic) blood, which is a finite resource. Cell salvage returns blood lost during surgery to the mother. It may avoid the need for donor blood transfusion, but reliable evidence of its effects is lacking. OBJECTIVES: To determine if routine use of cell salvage during caesarean section in mothers at risk of haemorrhage reduces the rates of blood transfusion and postpartum maternal morbidity, and is cost-effective, in comparison with standard practice without routine salvage use...

Toxoplasmosis is one of the most important causes of foodborne illnesses and inflammatory complications, as well as congenital disorders. Promiscuous Toxoplasma is transmitted by contaminated food and animal produce, water, vegetations, fruits and sexually through semen. Toxoplasma infects nucleated cells with a unique tropism for muscles and central nervous system and a mind bugging malicious effect. Pregnant women with acute or reactivated toxoplasmosis can transmit Toxoplasma via transplacental to the fetus...

Immunological disorders are among the main causes of recurrent spontaneous abortions (RSAs). Mesenchymal stem cells (MSCs) have been shown to modulate various aspects of immune responses. It seems that MSCs may improve the immunological conditions in immune-mediated RSA. The aim of this study is the reduction of resorption in RSA mouse model through MSCs therapy. The adipose-derived MSCs were administered intraperitoneal to pregnant CBA/J mice on day 4.5 of gestation in abortion-prone matting. On day 13.5 of pregnancy, abortion rates were calculated and transforming growth factor-β (TGF-β), interleukin 10 (IL-10), interferon γ (IFN-γ), and tumor necrosis factor α (TNF-α) gene expression in deciduas were evaluated by real-time polymerase chain reaction (PCR)...

INTRODUCTION: Gestational diabetes mellitus (GDM) is a state of glucose intolerance with onset during pregnancy. GDM carries prenatal and perinatal risks as well as long-term risks for the mother and her child. GDM may be involved in the foetal programming of long-term cardiovascular health. However, evidence is sparse and the effect of GDM on cardiovascular health is unknown. To address these issues, we will conduct MySweetHeart Cohort study. The objectives are to assess the effect of GDM on offspring's cardiovascular health early in life by using surrogate markers of cardiovascular disease and atherosclerosis...

BACKGROUND: Detection and quantitation of fetomaternal hemorrhage (FMH) can be difficult in patients with pre-existing elevations of HbF, such as those with hemoglobinopathies. The aim of this study was to evaluate the utility of dual-color flow cytometry with the Fetal Cell Count Kit (FCCK) in differentiating adult and fetal HbF in this population, as compared to flow cytometry (FC) using HbF alone. METHODS: Peripheral blood was obtained from normal adults and patients with hemoglobinopathies (β-thalassemia and sickle cell disease), including a small number of pregnant females...

Exposure to environmental contaminants during the critical window of pregnancy results in deregulation of highly coordinated genetic and epigenetic mechanisms involved in prenatal growth. Such disturbances significantly alter the fetal programming, and lead to various developmental disorders immediately, over the lifetime, or transgenerationally. During the process of placental development, fetal nucleic acids enter maternal plasma as a result of necrotic, apoptotic, and inflammatory mechanisms. These nucleic acids reflect normal or abnormal ongoing cellular changes during prenatal fetal development...

OBJECTIVE: Hepatitis is a prevalent infection in developing countries. While hepatitis B and C are deepening their roots in the developed world, hepatitis A and E are common in the developing world. The uniqueness of hepatitis is in its transformation from a relatively self-limiting disease in the non-pregnant state, to a highly virulent disease during pregnancy. MATERIALS AND METHODS: This retrospective observational study was conducted in the Department of Obstetrics and Gynecology, King George's Medical University, Lucknow, for a period of six months from June 2016 to November 2016 [probably during an endemic peak of hepatitis E virus (HEV)] to observe the clinical outcomes in HEV-infected pregnant women...

Pregnancy poses a challenge for the immune systems of placental mammals. As fetal tissues are semi-allogeneic and alloantibodies that commonly develop in the mother, the fetus and the placenta might be subject to complement-mediated immune attack with the potential risk of adverse pregnancy outcomes. Here, I describe how the use of animal models was pivotal in demonstrating that complement inhibition at the fetomaternal interface is essential for a successful pregnancy. Studies in animals also helped the identification of uncontrolled complement activation as a crucial effector in the pathogenesis of recurrent miscarriages, intrauterine growth restriction, preeclampsia, and preterm birth...

INTRODUCTION: Impaired placental maturation has been associated with retention of fetal membranes, which is a major reproductive disease in cattle. This maturation includes alterations in all tissue compartments of the placenta, specifically of epithelial and stroma cells and extracellular matrix. It is believed to be controlled by hormones, adhesion molecules and proteolytic enzymes. To investigate if the proteolytic enzyme heparanase and its substrates, the syndecans (SDCs) could be involved in the release of fetal membranes, their expression in bovine placentomes was analyzed...

Exaggerated maternal immune responses must be strictly controlled to ensure a successful pregnancy. Neutrophil extracellular traps (NETs) have recently been implicated as a potential mechanism for promoting inflammation in pregnancy-related disorders. In this study, we demonstrated that NETs play a key role in the pathogenesis of sphingosine kinase (Sphk)-mediated pregnancy loss. Perturbing the sphingolipid pathway by disrupting Sphk genes during pregnancy led to excessive NET formation exclusively at the fetomaternal interface and early fetal death...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a disease that may cause severe bleeding complications with risk of perinatal death or lifelong disability. The main cause of FNAIT is maternal antibodies against human platelet antigen (HPA)-1a. Both fetomaternal bleeding and transplacental trafficking of fetal cells during pregnancy could be the cause of alloimmunization. Persistence of fetal cells in the mother (fetal microchimerism) and maternal cells in the child (maternal microchimerism) are well-recognized phenomena...

The human placenta is a dynamic and heterogeneous organ critical in the establishment of the fetomaternal interface and the maintenance of gestational well-being. It is also the major source of cell-free fetal nucleic acids in the maternal circulation. Placental dysfunction contributes to significant complications, such as preeclampsia, a potentially lethal hypertensive disorder during pregnancy. Previous studies have identified significant changes in the expression profiles of preeclamptic placentas using whole-tissue analysis...
