The use of enoxaparin in addition to standard high-risk care does not reduce the risk of recurrence of preeclampsia and small-for-gestational-age infants in a subsequent pregnancy.

Color, pulsed and power Doppler were used to image the fetal pulmonary vasculature in 150 normal pregnancies and ten pregnancies in which the fetus had bilateral multicystic dysplastic kidney disease (MCDK) and associated pulmonary hypoplasia. The normal fetuses had a high resistance pattern in the main pulmonary artery vasculature. There were no significant changes in the resistance of the main pulmonary artery, right pulmonary artery and left pulmonary artery, with increasing gestational age. In the peripheral pulmonary arteries the resistance was less with an increase in diastolic flow, with advancing gestation. All fetuses with MCDK died. This group did not have significantly different Doppler waveforms in the main pulmonary arteries, but Doppler signals from the peripheral pulmonary arteries showed a high resistance pattern quite different from that of normal fetuses. Doppler measurements of the peripheral pulmonary artery may give additional information useful in diagnosing pulmonary hypoplasia.

The red fox Vulpes vulpes is one of the most destructive invasive species in mainland Australia and has recently been introduced to Tasmania. This paper reports the results of a survey conducted in Tasmania in mid-2006, to ascertain the public's views about foxes, their presence in Tasmania and what, if anything, should be done about them if, in fact, they are present. The survey found that public opinion among Tasmanians surveyed was overwhelmingly and vehemently opposed to the presence of foxes and indicated a high public expectation that there would be action by the authorities, scientists and others to remove them and/or prevent their further entry to the State. The minority of respondents who dissented from this view were chiefly in the "don't know" category, and required further information. The variation in responses by age to this and other questions indicates the desirability of a stronger communication focus on younger Tasmanians about foxes, the risks they pose and the need to use scientific methods to control them.
