Genetic influences on fibrinogen, tissue plasminogen activatorantigen and von Willebrand factor in males and females

Differences in genetic influence on death from CHD between males and females have been reported. Haemostatic factors have consistently been associated with risk for coronary heart disease (CHD), but sex differences in genetic architecture have not been studied...

Gestational age-specific distribution of twin birth weight discordance

Aim: To examine the gestational age-specific distribution of twin birth weight discordance.

Methods: We analyzed all liveborn twin sets between 28 and 40 weeks' gestation from the United States 1995–1998 Multiple Matched Birth Data Set compiled by the National Center for Health Statistics...

Puerperal complications following elective cesarean sections for twin pregnancies

Objective: To estimate the maternal puerperal morbidity in elective and emergent cesareans in twins.

Study design: We evaluated postpartum complications among patients who underwent elective cesarean birth for twin pregnancy...

Induction of labor with oral misoprostol in nulliparous mothers of twins

The efficacy and safety of oral misoprostol for labor induction of twins is unknown...

The Northwestern twin chorionicity study: testing the ‘placental crowding’ hypothesis

Objective: To evaluate the relation between placental proximity and frequency of birth weight discordance and small-for-gestational age (SGA) infants.

Study design: Retrospective three-tier chorionicity analysis of 1155 twin placentas comparing birth weight characteristics of the twins in different placental types.

Results: Dichorionic-separate, but not dichorionic-fused twins, are heavier than monochorionic-diamniotic and monoamniotic twins (2376±721 vs...

Increasing rates of sex-discordant twins no longer correspond to decreasing perinatal mortality rates

Objective: To analyze dizygotic twinning rates and outcomes over a 25-year period.

Methods: Birth and fetal death certificates from 1980–2004 in Washington State, USA, were analyzed retrospectively to find factors associated with the increase in sex-discordant twins through time...
