Nicolaides has developed methods of (i) screening for premature birth (which is the main cause of perinatal morbidity and mortality) by measurement of cervical length and prevention through the use of vaginal progesterone, [9] (ii) screening for pre-eclampsia (which is one of the main causes of maternal mortality) by measurement of blood flow ...
