Circular RNAs (circRNAs) have recently been shown to exert their effects on multiple pathological processes by acting as microRNA (miRNA) sponges. However, the roles of circRNAs in gestational diabetes mellitus (GDM) are largely unknown. This study aimed to identify the circRNAs involved in GDM and predict their potential biological functions. We first performed next-generation sequencing (NGS) to generate unbiased placental villi circRNA expression profiles of GDM and normal controls. In total, 48,270 circRNAs from the placental villi of the two groups were sequenced...

Diabetic ketoacidosis (DKA) during pregnancy is a serious metabolic complication of diabetes with high mortality and morbidity if not detected and treated immediately. We report a case of a woman with type 1 diabetes mellitus who had poorly controlled diabetes in the first half of pregnancy and developed DKA at 29 weeks gestation. At presentation, she had a pathological fetal heart tracing but delivery was delayed for maternal stabilisation and reversal of acidosis. Once hyperglycaemia, acidosis and maternal stabilisation were achieved, fetal compromise resolved and delivery was no longer indicated...

Recent studies have revealed considerable dysfunction of vascular endothelial cells (VECs) and abnormal expression of microRNA (miR)-137 in women with gestational diabetes mellitus (GDM), and the aim of this study was to clarify the underlying mechanism and possible role of microRNA (miR)-137 in dysfunction of VECs during GDM. We found increased levels of miR-137 in the plasma of GDM women and high-glucose (HG)-exposed HUVECs. Upregulating miR-137 in HUVECs elevated the chemokine (C-C motif) ligand 2 (CCL2) secretion and enhanced the chemotaxis and adhesion of U937 and THP-1 (two human acute monocytic leukemia cell lines) cells to HUVECs in a co-culture system...

OBJECTIVE: We assessed clinical outcomes and placental pathology among pregnancies complicated with gestational diabetes mellitus (GDM) according to their pregestational body mass index (BMI) and weight gain during pregnancy. STUDY DESIGN: Pregnancy outcome and placental pathological reports of all GDM deliveries, during 2009-2015, were reviewed. We compared women with pregestational BMI > 30 and or gestational weight gain >20 kg (high-BMI group), and women with pregestational BMI < 30 and weight gain less than 20 kg (normal BMI group)...

Extensive evidence suggests that the release of membrane enclosed compartments, more commonly known as extracellular vesicles (EVs), is a potent newly identified mechanism of cell-to-cell communication both in normal physiology and in pathological conditions. This article specifically reviews evidence about the formation and release of different EVs, their definitive markers and cargo content in reproductive physiological processes, and their capacity to convey information between cells through the transfer of functional protein and genetic information to alter phenotype and function of recipient cells associated with reproductive biology...

Parturition is defined as the action or process of giving birth to offspring. Normal term human parturition ensues following the maturation of fetal organ systems typically between 37 and 40 weeks of gestation. Our conventional understanding of how parturition initiation is signaled revolves around feto-maternal immune and endocrine changes occurring in the intrauterine cavity. These changes in turn correlate with the sequence of fetal growth and development. These important physiological changes also result in homeostatic imbalances which result in heightened inflammatory signaling...

Women with gestational diabetes (GDM) are a high risk group for early type 2 diabetes (T2D). Depression is a risk factor for T2D in the general population. We investigated in women after a recent pregnancy with GDM and without a clinical diagnosis of depression, whether mild to moderate depressive symptoms associate with pathologic glucose metabolism. In a cross-sectional analysis, we examined 173 women, 9 ± 3 months after delivery with several psychopathological assessments, 5-point oral glucose tolerance test with insulin, anthropometrics, and laboratory chemistry...

Cushing's syndrome (CS) occurs rarely during pregnancy. CS can be caused by prolonged abnormal exposure to excess glucocorticoids leading to special and significant signs and symptoms. It is often difficult to diagnose pathological hypercortisolism in pregnant women since some symptoms of the disease might be due to a complicated pregnancy, including preeclampsia or gestational diabetes. In this study, we report the case of a 29-year-old female who referred to our institution with hypertension, weakness, steria, and truncal obesity...

Maternal obesity during pregnancy is rising and is associated with increased risk of developing gestational diabetes mellitus (GDM), defined as glucose intolerance first diagnosed in pregnancy (1). Fetal growth is determined by the maternal nutrient supply and placental nutrient transfer capacity. GDM-complicated pregnancies are more likely to be complicated by fetal overgrowth or excess adipose deposition in utero . Infants born from GDM mothers have an increased risk of developing cardiovascular and metabolic disorders later in life...

Leptin is now considered an important signalling molecule of the reproductive system, as it regulates the production of gonadotrophins, the blastocyst formation and implantation, the normal placentation, as well as the foeto-placental communication. Leptin is a peptide hormone secreted mainly by adipose tissue, and the placenta is the second leptin-producing tissue in humans. Placental leptin is an important cytokine which regulates placental functions in an autocrine or paracrine manner. Leptin seems to play a crucial role during the first stages of pregnancy as it modulates critical processes such as proliferation, protein synthesis, invasion and apoptosis in placental cells...

Insulin resistance is characteristic of pregnancies where the mother shows metabolic alterations, such as preeclampsia (PE) and gestational diabetes mellitus (GDM), or abnormal maternal conditions such as pregestational maternal obesity (PGMO). Insulin signalling includes activation of insulin receptor substrates 1 and 2 (IRS1/2) as well as Src homology 2 domain-containing transforming protein 1, leading to activation of 44 and 42 kDa mitogen-activated protein kinases and protein kinase B/Akt (Akt) signalling cascades in the human foetoplacental vasculature...

Increased Lipoprotein associated phospholipase A2 (LpPLA2) has been associated with inflammatory pathologies, including Type 2 Diabetes. Studies on LpPLA2 and Gestational Diabetes Mellitus (GDM) are rare, and have focused mostly on maternal outcome. In the present study, we investigated whether LpPLA2 activity on foetal lipoproteins is altered by maternal GDM and/or obesity (a major risk factor for GDM), thereby contributing to changes in lipoprotein functionality. We identified HDL as the major carrier of LpPLA2 activity in the foetus, which is in contrast to adults...

Introduction Basal plate myometrium (BPMYO), the pathological presence of myometrial fibers in the basal plate, is a common finding on pathological examination of the placenta, yet its clinical correlates are not well studied. As myometrial fibers are frequently located in proximity to poorly converted maternal spiral arteries, our objective was to determine whether BPMYO is associated with hypertensive disorders of pregnancy (HDP), a well-known clinical sequela of abnormal maternal artery remodeling. Methods This case-control study included women who delivered a live-born singleton gestation whose placentas were sent for pathological examination...

AIM: Accumulating evidence suggested that challenge of the maternal-fetal interaction during pregnancy might cause the impairment of immunological hemostasis and lead to gestational diabetes mellitus (GDM) pathological process. Immune checkpoint molecule PD-1 is one of the critical molecule balancing immune response and immunological tolerance. METHODS: PD-1 expressions on T-cell subsets of GDM patients and control groups were measured via flow cytometric analysis and followed up...

Maternal nutrition plays a crucial role in influencing fetal growth and birth outcome. Any nutritional insult starting several weeks before pregnancy and during critical periods of gestation is known to influence fetal development and increase the risk for diseases during later life. Literature suggests that chronic adult diseases may have their origin during early life - a concept referred to as Developmental Origins of Health and Disease (DOHaD) which states that adverse exposures early in life "program" risks for later chronic disorders...

Bile acids are the amphipathic primary end-products of cholesterol metabolism that aid in digestion as well as participate in signal transduction in several hepatic and enteric pathways. Despite the reputation of bile acids as signaling molecules implicated in disease states such as cancer and diabetes, there remain numerous bile acid species that are weakly characterized in either physiological or pathological conditions. This review presents one such group: the flat or planar bile acids, a set of bile acids found in humans during infancy and occurring again during certain diseases...

INTRODUCTION: The prorenin (PR) receptor [(P)RR] contributes to the regulation of the tissue renin-angiotensin system (RAS) and Wnt signaling, which is involved in embryogenesis and the pathological progression of malignant tumors and diabetes mellitus. Placental (P)RR is significantly upregulated in placental tissues from preeclamptic women. However, because it cannot be examined during pregnancy, the chronological relationship between the acceleration of tissue RAS and the disease state of hypertensive disorder of pregnancy (HDP) has not been reported...
