INTRODUCTION Previous studies have found partners' smoking status, multiparity, and nicotine dependence to be associated with smoking cessation in pregnancy. However, no studies have investigated influences on cessation among women using nicotine replacement therapy (NRT). We analyzed data from a trial of NRT in pregnancy to determine factors associated with shorter- and longer-term cessation. ...

receiver operating characteristics (roc) curves have numerous applications for identifying a cut-off point in diagnostic tests. nonetheless, given that sometimes two cut-off points have to be specified simultaneously, the roc curve can be used to identify such points. the volume under the roc surface (vus) serves as a criterion for the accuracy of diagnostic tests. one of the unfortunate outcom...

OBJECTIVE Birthweight by gestational age charts enable fetal growth to be evaluated in a specific population. Given that maternal profile and obstetric practice have undergone a remarkable change over the past few decades in Spain, this paper presents new Spanish reference percentile charts stratified by gender, parity and type of delivery. They have been prepared with data from the 2010-2014 p...

The aim of this study was to evaluate the care of healthy full-term newborns and to identify variations in childbirth care and practices in the first hour of life. We used data from the Birth in Brazil survey. Unadjusted and adjusted odds ratio (OR) of hospital-delivered care for the mother and during childbirth were estimated for the following outcomes: upper airways and gastric aspiration, us...

BACKGROUND Post-spinal hypotension is a common maternal complication during cesarean delivery. Aortocaval compression by the gravid uterus has been assumed as a precipitating factor for post-spinal hypotension. The role of left lateral tilting position in improving maternal cardiac output after subarachnoid block (SAB) is unclear. The aim of this work is to investigate the effect of left latera...

background and objectives: preterm labor is a serious problem in obstetrics, accounting for 70% of perinatal mortality. high sensitive c - reactive protein (hs-crp) is a sensitive marker of inflammation. our aim in this study was to determine amniotic fluid hs-crp concentration and its correlation with pre-term delivery.   materials and methods: this prospective study was conducted on 90 pregna...

abstract background: preterm labor (delivery after 20 weeks and before 37 weeks of gestation) is the leading cause of prenatal mortality in developed countries. many women who have pre term labor have abnom1ally high plasma levels of a-fetoprotein in early pregnancy. methods: this study was designed to evaluate the ability of this biochemical test and a clinical risk factor scoring system to pr...

Objective To describe potential intrapartum complications for fetuses affected by absent pulmonary valve syndrome. Study Design Two cases of intrapartum fetal death at full term were collected from our institution's labor and delivery unit records. Results In both cases of intrapartum fetal death, the fetuses had been diagnosed with absent pulmonary valve syndrome and had likely experienced acu...

introduction: the risk of morbidity and mortality increases in neonates admitted to the neonatal intensive care units (nicus). various factors contribute to the prognosis of these newborns. in the current study, we aimed to investigate the role of mode of delivery on short-term neonatal outcomes. methods: this retrospective study was conducted on 215 neonates admitted to the nicu of shohada-e-t...
