Objective Studies have reported an increased risk of spontaneous preterm birth associated with elevated prepregnancy body mass index (BMI) among nulliparous but not multiparous women. We examined whether changes in BMI and weight between pregnancies contributed to risk of preterm birth among obese (BMI > 29 kg/m(2)) women. Study Design This study utilized maternally linked California birth reco...

background: the increase in the prevalence of cesarean section (c-section) in recent decades has become a public health problem worldwide. studies of cesarean section in order to identify the causes and form policies and interventions to reduce the incidence of this health problem are necessary. this study was conducted with the aim to investigate the causes of c-sections performed at niknafs a...

Introduction: To address the causes of maternal mortality and morbidity, reproductive health related disabilities is a motto World Health Organisation (WHO). Gestational hypertension constitutes as one main cause for morbidity mortality. Aetiology gestational hypertension- remains mystery. Mitochondrial dysfunction, particularly in trophoblastic cells, could play an important role causing postu...

OBJECTIVE To evaluate the predictive value of separate and combined tests using cell-free fetal DNA (cffDNA), cell-free total DNA (cfDNA), and biochemical markers for the early detection of pregnancies with hypertensive disorders. METHODS A nested case-control study was conducted with 135 singleton pregnancies including 17 gestational hypertension cases, 34 preeclampsia (PE) cases, and 84 con...

Objective: To compare the incidence and severity of pregnancy-induced hypertensive disorders in twin pregnancy and in singleton gestation. Study design: Case-control study in the setting of a University HOspital. Each pregnancy of a consecutive series of 187 twin pregnancies attending the antenatal clinic and booked before a gestational age of 24 weeks was matched for maternal age, parity, and ...

OBJECTIVE To examine the effect of hypertensive disease of pregnancy (HDP) on the development of respiratory distress syndrome (RDS) in preterm neonates. DESIGN A retrospective cohort study. SETTING All neonatal intensive care units in New South Wales and the Australian Capital Territory. PATIENTS A total of 18,845 preterm neonates aged between 24 and 36 weeks gestation admitted to the un...

Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements in the prediction of preeclampsia. Cop...

Introduction: Diabetes is a common metabolic disease during pregnancy. Preeclampsia is the most prevalent disorder that accompanies gestational diabetes. Recent studies have demonstrated the role of micronutrients in diabetic women with preeclampsia. The present study aimed to compare the levels of micronutrients in the women with gestational and hypertensive diabetes with and without preeclamp...
