BACKGROUND The purpose of this study was to compare the fetal/infant mortality risk associated with each additional week of expectant management to that associated with immediate delivery in women with multiple gestations. METHODS This was a retrospective national cohort study of 94,170 multiple deliveries, 92,619 (98.4%) twin and 1,352 (1.44%) triplet pregnancies, between 32 0/7 and 42 6/7 w...

OBJECTIVE To estimate the association between maternal body mass index (BMI) and risk of spontaneous preterm delivery (sPTD) and elective preterm delivery (ePTD) in singleton and multiple pregnancies. DESIGN Retrospective cohort study. SETTING Electronic records of all deliveries from 2009 through 2013 in a tertiary university hospital were abstracted for demographic and obstetrical informa...

We applied a noninvasive prenatal test for the determination of fetal gender in multiple pregnancies by using free fetal DNA circulating in maternal blood in order to evaluate whether the quantification of male DNA could distinguish the fetal gender and the number of male and female fetuses in multiple pregnancies. We enrolled consecutively 44 women with twin pregnancies between 11-14 weeks of ...

OBJECTIVE Multiple gestations are high risk pregnancies, which may be complicated by pre-maturity, low birth weight infants, pre-eclampsia, anemia, postpartum hemorrhage, intrauterine growth restriction, neonatal morbidity and high perinatal, neonatal and infant mortality. This study was carried out to determine the incidence and effect of multiple pregnancies on pre-term labor in tertiary care...

OBJECTIVE To determine risk of Down syndrome (DS) in multiple relative to singleton pregnancies, and compare prenatal diagnosis rates and pregnancy outcome. DESIGN Population-based prevalence study based on EUROCAT congenital anomaly registries. SETTING Eight European countries. POPULATION 14.8 million births 1990-2009; 2.89% multiple births. METHODS DS cases included livebirths, fetal ...

drug abuse in pregnancy is not uncommon, and the use of illicit opioids during pregnancy is associated with an increased risk of adverse outcomes. the aim of the study was to assess neonatal outcome of pregnancy with maternal addiction. materials and methods:   in this cohort study we assessed 100 pregnant women 15 -49 years old. to identify drug exposure was used self- questionnaire (self-repo...

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...

OBJECTIVES Placenta or placental chorangioma could be the origin site of infantile haemangioma since they share various histochemical and genetic characteristics with placental vascular tissue. The aim of the current study was to investigate the association between chorangiomas and infantile haemangiomas in singleton and multiple pregnancies. MATERIALS AND METHODS An informative questionnaire...
