Journal ArticleDOI

Perinatal management of extreme preterm birth before 27 weeks of gestation: a framework for practice.

TL;DR: This Framework has been developed by a multidisciplinary working group in the light of evidence of improving outcomes for babies born before 27 completed weeks of gestation, and evolving national and international changes in the approach to their care.
Journal ArticleDOI

In vivo assessment of failed trophoblastic invasion of the spiral arteries in pre-eclampsia.

TL;DR: The ability of colour/pulsed Doppler ultrasound to detect failed physiologic change of the spiral arteries in pregnancies complicated by pre‐eclampsia is assessed.
Journal ArticleDOI

Outcomes of labours augmented with oxytocin.

TL;DR: Significant improvements in the management of labours which fail to progress are needed if normal vaginal delivery rates are to approach those seen inlabours which progress without the need for augmentation.
Journal ArticleDOI

Telomere length dynamics differ in foetal and early post-natal human leukocytes in a longitudinal study

TL;DR: A more accentuated rate of telomere loss in leukocytes from pre term infants compared to human foetuses of comparable age followed longitudinally for 8–12 weeks in a longitudinal study points to a difference in HSC behaviour between foetal and early postnatal life which is independent of age but may be influenced by events at birth itself.
Journal ArticleDOI

Hematopoietic progenitor cell deficiency in fetuses and children affected by Down's syndrome

TL;DR: It is found that hematopoietic stem/progenitor cell deficiency and telomere shortening occurs in individuals with DS in fetal life, and it is proposed that stem cell deficiency may be a primary predisposing event to DS leukemia development.
