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...
The objective of this study was to determine endothelin (ET-1) concentrations in monochorionic twin fetuses with and without twin-twin transfusion syndrome (TTTS). Fourteen monochorionic twin pregnancies complicated by TTTS and six without TTTS were studied. Matched maternal and fetal blood samples were obtained both in utero and at birth. Amniotic fluid samples were also collected from twin pa...
There is a lack of research findings addressing the unique college admissions issues faced by twins and other multiples. The advantages and disadvantage twins face, as reported by college administrators, twins and families are reviewed. Next, recent research addressing twins' birth weight and neuromotor performance, transfusion syndrome markers, the vanishing twin syndrome and monozygotic (MZ) ...
Lamotrigine is frequently used to manage epilepsy during pregnancy. However, some major and minor birth defects are reported with lamotrigine monotherapy. This study is a case series report on 20 epileptic women who were receiving lamotrigine in their pregnancy. Apart from the normal pregnancies and births, in our study three patients gave birth to healthy twins, two vanished twin syndromes occ...
A study was made of seasonality in twin birth rate in Denmark between 1977 and 1984. We studied all twin births (N = 45,550) in all deliveries (N = 3,679,932) during that period. Statistical analysis using a simple harmonic sinusoidal model provided no evidence for seasonality. However, sequential polynomial analysis disclosed a significant fit to a fifth order polynomial curve with peaks in tw...
Localized birthweight references for gestational ages serve as an essential tool in accurate evaluation of atypical birth outcomes. Such references for twin births are currently not available in China. The aim of this study was to construct up-to-data sex specific birth weight references by gestational ages for twin births in China. We conducted a population-based analysis on the data of 22,507...
The effects of increasing fetal numbers and their distribution between the left and right uterine horns on calf survival, calf BW at birth and weaning, gestation length, dystocia, and calf sex ratio were evaluated for single (n = 1,587), twin (n = 2,440), and triplet calves (n = 147) born to primiparous and multiparous females in the Twinner population at the US Meat Animal Research Center betw...
BACKGROUND Twin pregnancies are commonly associated with low birth weight (LBW) infants. Most studies focus on growth of LBW compared with normal infants in singleton. However, there has not been any study on twins to compare LBW with normal birth weight (NBW) infants as a match control of the same twin. METHODS This cohort study was conducted at Healthcare centers of Kashan, in 2013. Twins d...
