PURPOSE: In the United States, an estimated 8500 HIV (human immunodeficiency virus) positive women gave birth in 2014. This rate appears to be increasing annually. Our objective is to examine obstetrical outcomes of pregnancy among HIV-positive women. METHODS: A population-based cohort study was conducted using the Nationwide Inpatient Sample database (2003-2011) from the United States. Pregnant HIV-positive women were identified and compared to pregnant women without HIV...

INTRODUCTION: Our aim was to investigate the rate of vascular dementia and dementia in women with previous hypertensive disorders in pregnancy since white matter lesions of the brain and cardiovascular disease are linked both to dementia and hypertensive disorders in pregnancy. MATERIAL AND METHODS: Prospective population based registry study on all women giving birth in Sweden between 1973- 1975 (284 598). Women with and without hypertensive disorders in pregnancy were identified by means of the Swedish Medical Birth Register and linked to the National Patient Register where data on somatic disease later in life were obtained...

Preeclampsia is an inflammatory disease with endothelial cell dysfunction that occurs via decreased endothelial nitric oxide synthase/nitric oxide (eNOS/NO) activity. Aspirin reduces the incidence of hypertensive pregnancy complications. However, the underlying mechanism has not been clearly explained. Here, we found that tumor necrosis factor (TNF)-α, microRNA (miR)-155, and eNOS levels as well as endothelial redox phenotype were differentially regulated in preeclamptic patients, implying the involvement of TNF-α- and redox signal-mediated miR-155 biogenesis and eNOS downregulation in the pathogenesis of preeclampsia...

OBJECTIVE: The aim of this systematic review and meta-analyses was to comprehensively describe the normotensive pattern of cardiac remodelling during human singleton pregnancies and compared to that during hypertensive complicated pregnancies. METHODS: We performed a meta-analysis of the current literature on cardiac remodelling during normotensive and complicated pregnancies. Literature was retrieved from PubMed (NCBI) and Embase (Ovid) databases. Included studies needed to report a reference measurement (matched non-pregnant control group, pre-pregnancy, or post-partum) and measurements during a predetermined gestational interval...

The endothelial nitric oxide (NO) system may be damaged in preeclampsia; however, the involved mechanisms are unclear. In this study, we used primary human umbilical vein endothelial cells (HUVECs) to evaluate the endothelial NO system in preeclampsia and to determine the underlying mechanisms that are involved. We isolated and cultured HUVECs from normal and preeclamptic pregnancies and evaluated endothelial NO synthase enzyme (eNOS) expression and NO production. Whole-cell K(+) currents and oxidative stress were also determined in normal and preeclamptic HUVECs...

Normoglycemic diabetic ketoacidosis should be suspected in pregnant women presenting nausea, vomiting, abdominal pain and anorexia. We report a 39 years old woman with a 32 weeks pregnancy who sought emergency care due to hyperemesis. She was hospitalized with the following diagnoses: pregnancy hypertension syndrome, gestational diabetes, morbid obesity and poor prenatal control. The evaluation of the feto-placental unit showed perception of fetal movements, non-reactive non-stress baseline record and a biophysical profile of 6/8...

The extent of the increased risk of pregnancy hypertensive disorders following assisted reproductive technology (ART) was investigated. PubMed and the Cochrane Collaboration Library were used as data sources to identify and select longitudinal cohorts comparing pregnancies following ART with spontaneously conceived pregnancies, between 1978 and June 2016. Risk ratios and 95% confidence intervals (CIs) of three outcomes, ie, gestational hypertension (GH), preeclampsia (PE), and their sum (PHD), were calculated...

BackgroundThe incidence of stroke in pregnant women is low but trending upward. There are few studies of the topic in women of Asian ethnicity.AimWe aim to evaluate stroke risk in Asian women during and after pregnancy.DesignUsing the Taiwan National Health Insurance database (NHIRD), we designed a retrospective study that included 18-45-year-old pregnant women between the years 2000 and 2010. We selected a 1:1 age-matched control group of non-pregnant women. The endpoint was any type of stroke during pregnancy or the postpartum period; otherwise, the patients were tracked until December 31, 2010...

Hypertensive disorders of pregnancy globally affect 6-8% of gestation and remain a major cause of both foetal and maternal morbidity and mortality. However, the antihypertensive medications for the patients of this disease are strictly limited due to the teratogenic potentials. Here, we found that tele-methylhistamine (tMH) increased in response to the administration of hydralazine (Hdz), a vasodilative agent, in the pregnancy-associated hypertensive (PAH) mice. Hdz abrogated the degradation of tMH catalyzed by monoamine oxidase B (MAO-B) in vitro These results suggested that Hdz inhibited the MAO-B activity and consequently tMH increased in the maternal circulation of PAH mice...

BACKGROUND: Despite the widely recognized association between the severity of early preterm birth (ePTB) and its related severe diseases, little is known about the potential risk factors of ePTB and the sub-population with high risk of ePTB. Moreover, motivated by a future confirmatory clinical trial to identify whether supplementing pregnant women with docosahexaenoic acid (DHA) has a different effect on the risk subgroup population or not in terms of ePTB prevalence, this study aims to identify potential risk subgroups and risk factors for ePTB, defined as babies born less than 34 weeks of gestation...

OBJECTIVE: Most small for gestational age pregnancies are unrecognised before birth, resulting in substantial avoidable perinatal mortality and morbidity. Our objective was to develop multivariable prediction models for small for gestational age combining clinical risk factors and biomarkers at 15±1 weeks' with ultrasound parameters at 20±1 weeks' gestation. METHODS: Data from 5606 participants in the Screening for Pregnancy Endpoints (SCOPE) cohort study were divided into Training (n = 3735) and Validation datasets (n = 1871)...

Defects in angiogenesis and mitochondrial function in the placenta contribute to the pathogenesis of preeclampsia; however upstream regulators of these pathways are not known. It has been argued that placental hypoxia secondary to abnormal spiral artery remodeling may play a causal role in the angiogenic and mitochondrial abnormalities noted in preeclampsia. The aim of this study was to evaluate the relationship between hypoxia-inducible factor-1α (HIF-1α) ¸ a surrogate of hypoxia, and soluble fms-tyrosine kinase 1 (sFlt1), a circulating anti-angiogenic factor, and microRNA 210 (miR-210), a microRNA that regulates mitochondrial function, in human placentas from preeclamptic and non-hypertensive pregnancies...
