TL;DR
A relationship is derived between the parameters of the proposed population model and the estimates obtained from a DLM fitted to mortality arising from the model that provides insight into the interrelationships between the size of the frail population, the number of lags of PM included in aDLM and the proportion of the effect of PM on the healthy population that is estimable.
Abstract
Three cases of fetus papyraceus in twin pregnancy were seen over a 4-month period. They were associated with an antepartum stillbirth and intrauterine growth retardation of the larger twin. Two of the 3 mothers exhibited hypertension. It is concluded, therefore, that the appearance of a fetus papyraceus frequently indicates the presence of a hostile intrauterine environment. We suggest that serial ultrasonic examinations be performed to confirm the diagnosis of fetus papyraceus. In this way, appropriate therapy may be directed toward a better outcome for the second twin.
