Expectant management of severe preterm preeclampsia: is intrauterine growth restriction an indication for immediate delivery?
Pregnancies complicated by severe preterm preeclampsia and the presence of intrauterine growth restriction at admission may not benefit from expectant management beyond the 48 hours needed for betamethasone to act. Furthermore, all patients may benefit from close fetal monitoring before delivery because of the high rate of intervention for deteriorating fetal status.
Mutations affecting different parts of the intracellular circadian clock can block the capacity to acquire rapid EtOH tolerance. However, the role of circadian genes in EtOH tolerance is independent of their role in producing circadian rhythmicity. The interference in the capacity to acquire EtOH tolerance by some circadian mutations is not merely a downstream effect of a nonfunctional circadian clock; instead, these circadian genes play an independent role in EtOH tolerance.
