OBJECTIVE To assess the effect of gestational age (GA) and cervical length (CL) measurements at transvaginal ultrasound (TVUS) in the prediction of preterm birth in twin pregnancy. DESIGN Individual patient data (IPD) meta-analysis. SETTING International multicentre study. POPULATION Asymptomatic twin pregnancy. METHODS MEDLINE and EMBASE searches were performed and IPD obtained from au...

background: controlled ovarian hyperstimulation (coh) in conjunction with intrauterine inseminations (iui) are commonly used to treat infertile couples. in this study we evaluated the relationship between iui outcome and special causes of infertility. we also aimed to examine parameters that might predict success following iui. materials and methods: in this cross-sectional study, we included 9...

fibroids are the most common benign tumors of the uterus during female reproductive age. uterine artery embolization (uae) using embolic particles (pva, gelfoam) to occlude the uterine arteries, have been reported as a relatively safe, effective, and durable nonsurgical alternative to hysterectomy in diminishing fibroid-related symptoms. to block the arterial blood supply to the fibroid complet...

BACKGROUND central nervous system (CNS) hyperperfusion is one of the events that constitute the pathophysiological basis for the clinical manifestations and complications of pre-eclampsia (PE). Detecting the increased flow in the CNS through Doppler flowmetry of the ophthalmic artery might precede the clinical onset of PE and could be used as a marker for subsequent development of PE. OBJECTI...

BACKGROUND The counselling of poor ovarian responders about the probability of pregnancy remains a puzzle for gynaecologists. The aim of this study was to optimise the management of poor responders by investigating the role of the oocyte-derived factor bone morphogenetic protein-15 (BMP-15) combined with chronological age in the prediction of the outcome of in-vitro fertilisation-embryo transfe...

Assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (ART). The current trend in human in vitro fertilization/embryo transfer (IVF/ET) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

background: anti-mullerian hormone (amh) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. the clinical application of amh measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies. objective: this study aimed to assess the relationship between the serum levels of amh and results ...

The aim of this study is to evaluate the diagnostic properties of waist circumference in the prediction of obesity-related gestational outcomes. Pregnant women 20 years or older were consecutively enrolled in six Brazilian State capitals from 1991 to 1995. Weight, height, and waist circumference were measured and an oral glucose tolerance test was performed. Patients were followed through child...

A single early quantitative hCG measurement 16 to 18 days after timed insemination has prognostic value with regard to pregnancy outcome in an asymptomatic, infertile population. Further, there is a statistically significant difference in the predictive value for hCG levels in patients less than or equal to 35 years compared with patients greater than 35 years of age. Interestingly, the same ag...

BACKGROUND Gestational diabetes mellitus (GDM) complicates 3-7% of all pregnancies and fetomaternal outcomes are strongly related to early diagnosis of GDM. The aim of this study was to determine the impact of risk factors in the prediction of an abnormal glucose challenge test (GCT). MATERIALS AND METHODS This was a prospective study conducted during 2009-2010 in two prenatal clinics in Rey,...
