Here the histopathology findings of placental infarction associated with late preterm birth are reported. The subject was a male neonate delivered at 34 weeks and 5 days of gestation with a birth weight of ∼2500 g. His mother had been diagnosed with a threatened premature birth at 27 weeks of pregnancy. The size and weight of the placenta was considered appropriate for gestational age. On the c...

In a one year prospective study in the Trent region we examined the short term outcome (survival to discharge) of all infants who required admission to a baby care unit. Infants of less than or equal to 28 weeks' gestation who received all their perinatal care in one of five large centres (each providing more than 600 ventilator days/year) showed significantly better survival rates than infants...

History of preterm labor is a strong risk factor for future preterm labor. Preterm labor is the leading cause of neonatal mortality in developed countries, but permanent morbidity in these premature neonates has many side effects for the newborn as well as th...

Renal sympathetic nerve activity (RSNA) increases rapidly after delivery of term fetal sheep and parallels the rise in heart rate (HR) and arterial pressure. To examine the RSNA response at birth in immature lambs, experiments were performed in chronically instrumented preterm fetal sheep (118- to 125-day gestation, term 145 days) before and after delivery by cesarean section. HR remained uncha...

Our objective was to investigate the effects of mode of delivery on neonatal outcomes among premature infants in a large cohort. STUDY DESIGN We applied a retrospective cohort study design to a database of 6,408 births. Neonates were stratified by birth weight and a composite...
