Is the cardiac cycle a major contributor to variability in size measurements of abdominal aortic aneurysms by ultrasound?
The lack of a standardised measurement of the AAA diameter during the cardiac cycle is a potential major contributor to the variability in ultrasonography measurements.
We hypothesize that pregnant women in regions with high yellow fever vaccination coverage may pose their offspring to lower risk for development of microcephaly. There is an urgent need for systematic studies to confirm the possible link between low yellow fever vaccination coverage, Zika virus infection and microcephaly.
