Studies have shown that velamentous cord insertion is associated with impaired fetal growth both in twins 43, 45 and in singletons 44.
Secondly, either the n 1 or the n 1 + 1 occur in singletons.
To compare the rate of neonatal respiratory morbidity in singletons versus twins delivered by pre-labour caesarean section.
In twins, the rate of preterm birth is higher than in singletons; interventions to prevent preterm birth are needed in this high-risk population.
To study perinatal outcomes in singletons born after intrauterine insemination (IUI) compared with children born after in vitro fertilization (IVF), intracytoplasmic sperm injection, and spontaneous conception (SC), and to assess predictors of poor outcome in singletons born after IUI, exploring the effect of ovarian stimulation.
Previous studies have shown a higher risk of birth defects and preterm birth (PTB) in singletons born after blastocyst transfer as compared to singletons born after cleavage-stage transfer.
The aim of this study was to investigate the prevalence of selected dental variations in association with infraocclusion, as well as determining the effects of infraocclusion on dental development and tooth size, in singletons and twins.
Fisk et al. also provided data on IUP in multiple gestations which were not significantly different from those in singletons.
The positive associations between birth weight and adult hand grip strength are consistent with those observed in singletons and show similar effect sizes [3], [4], [5], [6], [7].
Nearly 3% of these ORFs are in singletons, most of which have significant but not full-length similarity to other ORFs, so they could not be clustered.
Nevertheless, when predicting preterm delivery in twin pregnancies, a higher cervical length cut-off than in singletons has been recommended because of the greater prevalence of preterm delivery.
