Background: Multiple pregnancies are responsible for the increased risk of maternal and neonatal morbidity and mortality. This study aimed to compare the perinatal outcome between multiple and singleton pregnancies. Materials and Methods: This is a retrospective cohort study. A sample of 50 multiple birth neonates- born in Fatemieh Hospital of Hamadan, Iran in 2015- was selected using simple r...

Ultrasound has revolutioned the care of women carring twins. First trimester evaluation is the best time to determine chorioniocity and amnioniocity in multiple gestations. First trimester diagnosis is based on the number of gestational sacs, amnions and yolk sacs. Growth rate in multiple multiple gestations during the fist and early second trimesters parallels the growth rate of singleton preg...

Physiological status and litter size affect ewes' hematological parameters, which serve as health indicators. These parameters reflect changes in an animal's physiological condition. Therefore, this study examined the profiles of Awassi ewes with single twin pregnancies during pregnancy postpartum. A total 232 sexually mature healthy (123 109 pregnancies) between ages 3 4 years were included cu...

background: there is no published data on the association between serum biochemical and ultrasonographic markers and adverse pregnancy outcomes. therefore, the aim of this study was to determine the factors associated with perinatal outcomes in singleton pregnancies using ultrasound and maternal serum markers during the first trimester in panamanians. materials and methods: this was a prospecti...

Advances in treating infertile couples by assisted reproductive technologies (ART) over more than three decades have greatly improved the chances of better outcomes. While twinning and higher order multiple birth rates are still high in most countries, lower rates have sometimes been achieved by single-embryo transfer. Multiple preg- Abstracts of the 12th Royan International Congress on Reprodu...

BACKGROUND Singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. However, singletons conceived after ART are found to have a poor perinatal outcome in comparison to naturally conceived singletons. It was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sha...

OBJECTIVES To determine the levels of first-trimester free beta-human chorionic gonadotrophin (free betahCG), pregnancy-associated plasma protein A (PAPP-A) and nuchal translucency (NT) in twin pregnancies. METHODS The study included 93 patients with twin pregnancy and 4,977 with singletons who underwent first-trimester testing using free betahCG, PAPP-A and NT at 10-13 weeks of gestational a...

Ductus venosus (DV) is a tiny vessel with a central role in fetal circulation both in singletons and multiples. In the present review we detail the contribution of DV evaluation in twin pregnancies in the first trimeter of pregnancy. The higher prevalence of abnormal A-wave in fetuses with abnormal karyotype and/or cardiac defects made DV evaluation a useful marker for the screening of chromoso...
