AIMS: The risk of cardiovascular disease in women with gestational diabetes is poorly understood. We sought to determine whether gestational diabetes increases the risk of cardiovascular disease more than two decades after pregnancy. METHODS: We carried out a retrospective cohort study of 1,070,667 women who delivered infants in hospitals within Quebec, Canada, between 1989 and 2013. We followed 67,356 women with gestational diabetes and 1,003,311 without gestational diabetes for a maximum of 25...

INTRODUCTION: Statins are a class of drugs, which act by inhibiting the rate-limiting enzyme of cholesterol biosynthesis (3-hydroxy-3-methyl-glutaryl-CoA reductase). The inhibition of mevalonate synthesis leads to subsequent inhibition of downstream products of this pathway, which explains the pleiotropic effects of these agents in addition to their well-known lipid-lowering effects. Accumulating evidence suggests that statins might be beneficial in various obstetric and gynecologic conditions...

DNA-functionalized nanoparticles, when paired with surface-enhanced Raman spectroscopy (SERS), can rapidly detect microRNA. However, widespread use of this approach is hindered by drawbacks associated with large and expensive benchtop Raman microscopes. MicroRNA-17 (miRNA-17) has emerged as a potential epigenetic indicator of preeclampsia, a condition that occurs during pregnancy. Biomarker detection using an SERS point-of-care device could enable prompt diagnosis and prevention as early as the first trimester...

BACKGROUND: Impaired placentation in the first 16 weeks of pregnancy is associated with increased risk of subsequent development of preeclampsia, birth of small for gestational age neonates and placental abruption. Previous studies reported that prophylactic use of aspirin reduces the risk of preeclampsia and small for gestational age neonates with no significant effect on placental abruption. However, meta-analyses of randomized controlled trials examining the effect of aspirin in relation to gestational age at onset of therapy and dose of the drug reported that significant reduction in the risk of preeclampsia and small for gestational age neonates is achieved only if the onset of treatment is at ≤16 weeks of gestation and the daily dose of the drug is ≥100 mg...

Pregnant women with type I diabetes mellitus (T1DM) are at increased risk of developing preeclampsia (PE). Plasminogen is aberrantly filtrated from plasma into tubular fluid in PE patients and activated to plasmin. Plasmin activates the epithelial sodium channel in the collecting ducts potentially causing impaired sodium excretion, suppression of the renin-angiotensin-aldosterone system, and hypertension in PE. The objective of the study was to test whether urinary total plasmin(ogen)/creatinine ratio and plasma concentration of aldosterone were better predictors of PE in pregnant women with T1DM compared with urine albumin and haemoglobin A1C...

Magnesium sulfate (MgSO4) is drug of choice for both prevention of eclampsia in women with severe preeclampsia and treatment of eclampsia. Antenatal MgSO4 is now emerging as popular neuroprotective agent in preterm neonates. However, recent studies reported an association of antenatal MgSO4 with feed intolerance, necrotizing enterocolitis and spontaneous intestinal perforation in extremely preterm neonates. In this review article, we discuss both aspects of antenatal MgSO4 in preterm neonates.

Pregnancies affected by preeclampsia (PE) or fetal growth restriction (FGR) display increases in thrombin generation and reductions in angiogenesis and cell growth. There is significant interest in the potential for low molecular weight heparins (LMWHs) to reduce the recurrence of PE and FGR. However, LMWH is associated with an increased risk of bleeding. Therefore, it is of vital importance to determine the exact molecular function of heparins in pregnancy if they are used as therapy for pregnant women. We aimed to determine this using our model for PE/FGR in microvascular endothelial cells...

BACKGROUND: Mothers are increasingly given greater control over many of the choices around birth, although there is little robust evidence to inform these choices. After an infant is born with HIE the question of whether it was predictable, or preventable, is often raised. Intrapartum 'sentinel' events and antenatal predictors of HIE have been well described, however there is little evidence how antenatal and intrapartum factors interact. This is particularly important when elective delivery by lower segment caesarean section (LSCS) has been shown to be beneficial in high risk groups...

Atypical HUS (aHUS) is a disorder most commonly caused by inherited defects of the alternative pathway of complement, or the proteins that regulate this pathway, and life-threatening episodes of aHUS can be provoked by pregnancy. We retrospectively and prospectively investigated 27 maternal and fetal pregnancy outcomes in 14 women with aHUS from the Vienna Thrombotic Microangiopathy Cohort. Seven pregnancies (26%) were complicated by pregnancy-associated aHUS (p-aHUS), of which three appeared to be provoked by infection, bleeding, and curettage, and three individuals were considered to have preeclampsia/HELLP syndrome before the definitive diagnosis of p-aHUS was made...

BACKGROUND: Women are encouraged to be physically active during pregnancy. Despite available evidence supporting antenatal physical activity to bring health benefits for both the mother and child, the most effective way to prevent some maternal and fetal outcomes is still unclear. The purpose of this study was to evaluate the efficacy of an exercise intervention to prevent negative maternal and newborn health outcomes. METHODS: A randomized controlled trial (RCT) nested into the 2015 Pelotas (Brazil) Birth Cohort Study was carried-out with 639 healthy pregnant women, 213 in the intervention group (IG) and 426 in the control (CG) group...

Preeclampsia is a pregnancy-specific disorder of new-onset hypertension and proteinuria after 20 weeks' gestation, often resulting in poor outcome. Previous studies demonstrated that apelin is an endogenous active peptide with visodilation and anti-oxidative stress capabilities. The present study investigated the effects of apelin in a rat model of preeclampsia induced by reduced uterine perfusion pressure (RUPP). Rats with RUPP displayed hypertension and poor pregnancy outcomes, such as decreased fetal and placental weight...

Preeclampsia is a dangerous disorder of pregnancy, defined as hypertension with proteinuria. Its nature remains elusive, and measures of prevention and treatment are limited. Observational studies have suggested that preeclampsia is associated with low intake of omega-3 long-chain polyunsaturated fatty acids (LCPUFA). In recent decades, researchers studied LCPUFA supplementation as a measure to prevent preeclampsia. Most of these trials and later systematic reviews yielded negative results. However, these trials had several important limitations associated with heterogeneity and other issues...

REVIEW
Katie M Groom, Anna L David
Fetal growth restriction and related placental pathologies such as preeclampsia, stillbirth, and placental abruption are believed to arise in early pregnancy when inadequate remodeling of the maternal spiral arteries leads to persistent high-resistance and low-flow uteroplacental circulation. The consequent placental ischaemia, reperfusion injury, and oxidative stress are associated with an imbalance in angiogenic/antiangiogenic factors. Many interventions have centered on the prevention and/or treatment of preeclampsia with results pertaining to fetal growth restriction and small-for-gestational-age pregnancy often included as secondary outcomes because of the common pathophysiology...

Low molecular weight heparin has been extensively evaluated for the prevention of preeclampsia in high-risk pregnant women, however, the results from these trials have been conflicting. This review discusses the potential mechanisms of action of low molecular weight heparin for the prevention of severe preeclampsia, how to optimize the selection of high-risk women for participation in future trials and the importance of trial standardization.

INTRODUCTION: Maternal endothelial dysfunction underlying preeclampsia arises from excessive placental release of anti-angiogenic factors, such as soluble fms-like tyrosine kinase-1 (sFlt1), soluble endoglin (sEng) and activin A. Resveratrol, an activator of the nuclear factor erythroid 2-related factor-2 (Nrf2) transcription factor, mediates the gene expression of antioxidant and vasoprotective factors that may counter the endothelial damage imposed by these anti-angiogenic factors. The objective of this study was to assess whether resveratrol could reduce placental oxidative stress and production of anti-angiogenic factors in vitro and/or improve in vitro markers of endothelial dysfunction via Nrf2 activation...

PROBLEM: Vitamin D deficiency increases the risk of developing pregnancy-related complications, including preeclampsia and small-for-gestational-age infants. Vitamin D was demonstrated to promote the invasiveness of human extravillous trophoblasts (EVTs). However, whether vitamin D induces the epithelial-mesenchymal transition (EMT) of EVTs remains unclear. Therefore, we investigated whether vitamin D promotes EMT and the related signaling pathways. METHOD OF STUDY: In this study, we performed EMT experiments using JAR cells based on the expression of the mesenchymal markers and vitamin D receptor...

The pathogenesis of preeclampsia remains unclear but placental factors are known to play a crucial role causing maternal endothelial cell dysfunction. One potential factor is placental micro- and nano- vesicles. Antiphospholipid antibodies (aPL) increase the risk of preeclampsia ten-fold, in part by damaging the mitochondria in the syncytiotrophoblast. Since mitochondrial DNA (mtDNA) is a danger- associated molecular pattern (DAMP/alarmin) that may activate endothelial cells, the aims of the current study were to investigate whether aPL affect the number of placental vesicles extruded, their mtDNA content and their ability to activate endothelial cells...

OBJECTIVE: Preeclampsia (PE) is a severe pregnancy complication with significant maternal and neonatal morbi-mortality resulting in high health care costs. Prevention, mainly based on the administration of acetylsalicylic acid, is only possible if timely identification of high-risk patients can be realized in an easy, nonexpensive, and widely available method. This paper explores the clinical usability of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and/or mean platelet volume (MPV) in discriminating between women that will and those that will not develop PE...
