OBJECTIVE: The predictive value of spot urine protein-to-creatinine ratio (PCR) for estimating total 24-hour proteinuria in severe preeclampsia is unclear. This study aimed to assess the diagnostic accuracy of spot urine PCR for ascertaining the magnitude of proteinuria in women with preeclampsia of varying severity. METHODS: A total of 205 patients with prediagnosed preeclampsia were included in this prospective cohort study. Patients were allocated into one of the three groups categorized by severity of disease, as follows: gestational hypertension, group 1 (n = 41); preeclampsia, group 2 (n = 88); and severe preeclampsia, group 3 (n = 76)...

BACKGROUND: Placental Growth Factor (PGF) is important for wound-healing and vascular collaterogenesis. PGF deficiency is associated with preeclampsia, a hypertensive disease of human pregnancy. Offspring born to preeclamptic mothers display cognitive impairments and brain vascular and neurostructural deviations. Low PGF production during development may contribute to alterations in offspring cerebrovascular beds. Retina is a readily accessible part of the central nervous system with a well-described pattern of vascular development in mice...

OBJECTIVE: To examine if a "dose-response" relation exists between different classes of pre-gravid obesity and selected perinatal outcomes. METHODS: We evaluated 16,566 obese mothers, including 12,064 (72.8%), 3410 (20.6%), and 1092 (6.6%) with obesity class I, II, and III, respectively. We compared maternal age, primiparity, gestational age at birth, birth weight, GDM, hypertensive disorders, and the incidence of cesarean sections. RESULTS: There was a significantly increased incidence (from class I to class III) for GDM (8...

Purpose To assess the impact of pre-pregnancy obesity (body mass index [BMI] ≥ 30 kg/m(2)) on the gestational and perinatal outcomes. Methods Retrospective cohort study of 731 pregnant women with a BMI ≥ 30 kg/m(2) at the first prenatal care visit, comparing them with 3,161 women with a BMI between 18.5 kg/m(2) and 24.9 kg/m(2). Maternal and neonatal variables were assessed. Statistical analyses reporting the demographic features of the pregnant women (obese and normal) were performed with descriptive statistics followed by two-sided independent Student's t tests for the continuous variables, and the chi-squared (χ(2)) test, or Fisher's exact test, for the categorical variables...

OBJECTIVE: Hypertensive disorders of pregnancy (HDP) are associated with impaired placentation, as evidenced by abnormal uterine artery (UtA) Doppler. UtA mean pulsatility index (PI) shows a progressive decline with gestational age (GA). However, previous studies have reported that a proportion of pregnancies demonstrate worsening of the UtA Doppler. The aim of this study was to investigate the incidence of HDP according to the change in the UtA mean PI between the second and third trimester...

Sclerosing stromal tumors of the ovary are very rare. We report the case of a 29-year-old pregnant woman who presented with a history of preterm labor and gestational hypertension. A huge mass measuring 30 cm in greatest dimension was recognized on the right ovary during cesarean section. Signet ring cell infiltration was seen during intraoperative frozen section consultation. She underwent a right salpingo-oophorectomy, and the permanent diagnosis was sclerosing stromal tumor infiltrated by signet ring cells...

BACKGROUND: Considering long-term changes in renal sodium handling and blood pressure in maternal protein-restricted (LP) offspring, we assumed that the development of LP hypertension results from abnormal dorsal root ganglia (DRG) neurokinin expression associated with impaired responsiveness of renal sensory receptors, promoting a reduced urinary excretion of sodium. The present study investigates whether increased blood pressure in protein-restricted offspring would be associated with changes in the DRG cells and in renal pelvic wall expression of NK1R, SP and CGRP when compared to NP offspring...

Despite the implementation of programmes to improve maternal health, maternal and foetal mortality rates still remain high. The presence of maternal distress and its association with the development of pregnancy hypertensive disorders is not well established. The aim of this study was to evaluate the association between maternal distress and the development of hypertensive disorders in pregnancy in a prospective cohort of 321 Mexican women. Symptoms of maternal distressing were evaluated at week 20th of gestation using the General Health Questionnaire...

Immunomodulation by mesenchymal stem cells (MSCs) is potentially important for maintaining peripheral tolerance. Preeclampsia may be due to maternal immune rejection of the genetically foreign fetus. This study aimed to investigate the biological function of human umbilical cord-derived mesenchymal stem cells (HU-MSCs) for the treatment of angiotensin receptor agonistic autoantibody (AT1-AA)-induced hypertension during pregnancy. HU-MSCs were isolated, cultured, and labeled in vitro. AT1-AA and HU-MSCs were administered to pregnant rats...

OBJECTIVES: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral small vessel disease caused by NOTCH3 gene mutations. CADASIL women are frequently considered at high risk of systemic vascular events during pregnancy and often prescribed with antithrombotic drugs. This decision is not evidence-based considering the lack of data about pregnancy outcome in CADASIL. We describe our experience on pregnancy in CADASIL patients...

We describe a patient with Class C diabetes who presented for nonstress testing at 36 weeks and 4 days of gestation with nonreassuring fetal heart tones (NRFHT) and oligohydramnios. Upon delivery, thrombosis of the umbilical cord was grossly noted. Pathological analysis of the placenta revealed chorangiosis, vascular congestion, and 40% occlusion of the umbilical vein. Chorangiosis is a vascular change of the placenta that involves the terminal chorionic villi. It has been proposed to result from longstanding, low-grade hypoxia in the placental tissue and has been associated with such conditions such as diabetes, intrauterine growth restriction (IUGR), and hypertensive conditions in pregnancy...

Preeclampsia, a multisystem hypertensive disorder of pregnancy, is associated with increased systemic vascular resistance. Placentae from patients with preeclampsia have reduced levels of endothelial nitric oxide synthase (eNOS) and, thus, less nitric oxide (NO). Syncytiotrophoblast extracellular vesicles (STBEV), comprising microvesicles (STBMV) and exosomes, carry signals from the syncytiotrophoblast to the mother. We hypothesized that STBEV-bound eNOS (STBEV-eNOS), capable of producing NO, are released into the maternal circulation...

OBJECTIVE: During controlled ovarian stimulation in IVF, supraphysiologic levels of estradiol (E2) have been associated with poor placentation and adverse pregnancy outcomes. This study aimed to investigate whether high peak E2 on the day of human chorionic gonadotropin trigger is associated with low pregnancy-associated plasma protein-A (PAPP-A) and adverse perinatal outcomes. METHODS: We performed a retrospective cohort study at a private, university-affiliated fertility centre in Vancouver, BC...
