AIMS: Maternal alcohol drinking adversely affects pregnancy outcome. Although fetal health and development are highly dependent upon the integrity of placentation, little is known about placental morphology following gestational exposure to alcohol in humans. METHODS: In this clinical study, subjects were recruited between 2010 and 2013 from an outpatient substance abuse and mental health treatment center for women. Data collected included maternal age, substance abuse history, comorbidities, pregnancy outcomes, gestational age at delivery, birth weight and placental weight...

Physiologically, a successful pregnancy requires the maternal immune system to recognize and tolerate the semiallogeneic fetus, and allow for normal invasion of trophoblasts. Thus, pregnancy complications are considered to be associated with dysfunctional maternal-fetal crosstalk. Co-signaling molecules are a group of cell surface molecules that positively or negatively modulate the immune response. Well studied in the fields of oncology and transplantation, they are also suggested to be involved in maternal-fetal crosstalk...

Pyrethroid insecticides are extensively used in agriculture and in household activities. During pregnancy, they might affect maternal metabolic status and there after fetal development. In this work, we studied metabolic and redox effects of low dose alpha-cypermethrin exposure in pregnant rats and their offspring. The diet containing alpha cypermethrin at 0.02mg/kg/day was consumed during the entire gestation. Plasma biochemical parameters as well as liver lipid and oxidative stress markers were determined...

AIMS: Severe preterm fetal growth restriction (FGR) remote from term is problematic. We aimed to investigate the effect of maternally-administered antithrombin on maternal and neonatal outcomes. A prospective, one-arm, pilot study was performed in 14 women with severe FGR (≤5th centile) at <28 weeks of gestation, without hypertensive disorders. Maternal plasma concentrations of soluble Feline McDonough Sarcoma (FMS)-like trypsin kinase-1 (sFlt-1) and placental growth factor (PlGF) were measured and categorized into three groups: group 1; low sFlt-1 and high PlGF, group 2; moderate sFlt-1 and low PlGF, and group 3; high sFlt-1 and low PlGF...

The factors determining Fatty acid transfer across the placenta are not fully understood. This study used a combined experimental and computational modelling approach to explore placental transfer of non-esterified fatty acids and identify rate-determining processes. The isolated perfused human placenta was used to study the uptake and transfer of [(13)C]-fatty acids and the release of endogenous fatty acids. Only 6.2 ± 0.8% of the maternal (13)C-fatty acids taken up by the placenta was delivered to the fetal circulation...

Blood group alloimmunization is "triggered" when a person lacking a particular antigen is exposed to this antigen during transfusion or pregnancy. Although exposure to an antigen is necessary for alloimmunization to occur, it is not alone sufficient. Blood group antigens are diverse in structure, function, and immunogenicity. In addition to red blood cells (RBCs), a recipient of an RBC transfusion is exposed to donor plasma, white blood cells, and platelets; the potential contribution of these elements to RBC alloimmunization remains unclear...

Pregnancy and the postpartum period substantially increase the risk for thrombotic events. Although the absolute risk for thrombosis is low, these events comprise a significant portion of maternal morbidity and mortality. The vast majority of such events are venous, although the risk for ischemic stroke also appears to be increased in pregnancy. This review will explore the overlapping and unique risk factors for venous and arterial thrombosis in pregnancy. Diagnosis and prevention will be discussed, and treatment will be briefly touched on...

BACKGROUND: There has been a recent increase in the number of newborns with brain malformations due to congenital infections, but the impact of these diseases remains largely under ascertained in middle-income and low-income countries. This case report presents a fetal anencephaly following maternal toxoplasma and rubella co-infection in a resource-limited setting and the challenges faced by the patient and the health care provider in the management of the condition. CASE PRESENTATION: A 25-year-old black Cameroonian woman of Bakossi origin, gravida3 para1010, presented with a positive rubella and toxoplasma immunoglobulin G serologic test at 21 weeks of pregnancy; she could not benefit from a fetal morphologic ultrasound partly because there was none at the site of her antenatal clinic and because there were accessibility constraints getting to the nearest referral hospital approximately 100 km away...

Pregnancy-induced hypertension (PIH, including preeclampsia [PE] and gestational hypertension [GH]) and cardiovascular diseases (CVDs) have some metabolic changes and risk factors in common. Many studies have reported associations between single nucleotide polymorphisms (SNPs) of renin-angiotensin-aldosterone system (RAAS) genes and CVDs (particularly hypertension), and their findings have provided candidate SNPs for research on genetic correlates of PIH. We explored the association between hypertension-related RAAS SNPs and PIH in a Chinese population...

INTRODUCTION: Pituitary disorders during pregnancy are uncommon. The approach should include a close follow-up in order to reduce maternal and fetal risks associated with physiological changes during pregnancy or treatment side effects. MATERIALS AND METHODS: We report a 21-year-old woman with a thyroid-stimulating hormone-secreting pituitary macroadenoma and positive antithyroid antibodies. She was initially treated using transsphenoidal pituitary surgery. The patient relapsed 17-month post-surgery...

Pregnant women with neurofibromatosis type 1 (NF-1) have increased complications during gestation, including hypertensive disorders that are sometimes caused by pheochromocytoma. Pheochromocytoma is an extremely rare condition during pregnancy, and the main clinical manifestation is hypertension. If not properly treated, pheochromocytoma has high maternal and fetal mortality rates. Early recognition and adequate clinical management before delivery have led to better outcomes in the last few decades. Despite the association of NF-1 and pheochromocytoma, there are few clinical reports of these two conditions in pregnant patients...

Iron is essential for the oxidative metabolism of lipids. Lipid metabolism changes during gestation to meet the requirements of the growing fetus and to prepare for lactation. The temporal effects of iron deficiency during gestation were studied in female rats fed complete or iron-deficient diets. Plasma triglycerides were elevated in the iron-deficient group throughout gestation. There were time-dependent changes in the triglyceride content of the maternal liver, falling at the midpoint of gestation and then increasing on d21...

REVIEW
Binqing Fu, Haiming Wei
During early pregnancy, an orchestrated evolutionary maternal adaption toward tolerance of the semiallogeneic fetus is required to ensure decidualization and early embryo development. Remodeling of the immune system involves natural killer cells (NKs), macrophages, T cells and dendritic cells (DCs) altering the microenvironment in the deciduas. In particular, a unique population of NK cells with a CD56(bright)CD16(-) phenotype in the decidua has been proposed to play a key role in the maternal adaptation to pregnancy...

Excessive placental inflammation is associated with several pathological conditions, including stillbirth and fetal growth restriction. Although infection is a known cause of inflammation, a significant proportion of pregnancies have evidence of inflammation without any detectable infection. Inflammation can also be triggered by endogenous mediators, called damage associated molecular patterns or alarmins. One of these damage-associated molecular patterns, uric acid, is increased in the maternal circulation in pathological pregnancies and is a known agonist of the Nlrp3 inflammasome and inducer of inflammation...
