Mean platelet volume is a more significant biomarker of pre-eclampsia. It is more significantly associated with this condition than other routinely measured laboratory markers such as platelet count. MPV is routinely obtained on complete blood cell count and its utilization in the assessment of pre-eclampsia in a clinical setting should continue to be evaluated.
Twin reversed arterial perfusion (TRAP)
CASE REPORTA 22-year-old woman, gravida 1 para 0, was found to have a triplet pregnancy at an initial 21-week comprehensive ultrasound examination. Fetal demise with hydropic changes in one of the fetuses was initially suspected. A subsequent ultrasound examination by a maternal-fetal medicine specialist confirmed a monochorionic-triamniotic triplet gestation with absence of cardiac activity in one of the triplets. Additionally, reversed flow in the umbilical cord of this fetus was demonstrated on Doppler ultrasound examination. These findings were consistent with a monochorionic-triamniotic gestation complicated by twin reversed arterial perfusion (TRAP) sequence.On evaluation at our center at 22 + 5 weeks' gestation, Doppler examination confirmed reversed flow through the single umbilical artery of the acardiac fetus, Triplet A. Generalized soft-tissue edema was seen and the amniotic fluid volume was normal (Figure 1). Triplet B, the suspected pump fetus (estimated fetal weight, 377 g), showed an increased amniotic fluid volume with a
Objective To compare outcome of dichorionictriamniotic (DCTA) triplet gestations with that of a paired cohort of monochorionic-diamniotic (MCDA) twin gestations undergoing laser therapy for treatment of twin-to-twin transfusion syndrome (TTTS).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
