The effect of previous preterm birth on the risk of recurrent preterm birth in Iceland 1997-2018
Background: Previous preterm birth and maternal age are known risk factors for preterm birth. Studies have shown a higher recurrence risk with a lower gestational age in the previous birth and that the clinical subtype of preterm birth is likely to recur. There is no current evidence regarding the …

Review of Late Preterm birth at Mowbray Maternity Hospital
Introduction: Preterm births are common in all obstetric hospitals and present multiple challenges to both the obstetrician and the paediatrician. Preterm delivery is an important cause of perinatal morbidity and mortality, and places significant psychosocial stress on all involved. Late Preterm …

PRETERM BIRTH, PHYSICAL ACTIVITY, AND ARTERIAL STIFFNESS IN YOUNG ADULTS
… stiffness and physical activity (PA) between preterm (PT) and term-born (T) young adults and determine if PA is a partial mediator of arterial stiffness. METHODS: 68 PT (31 M) and 33 T (15 M), 18-23 yrs old, participated. Arterial stiffness was assessed via applanation tonometry from which …

The Placental Microbiome and Preterm Birth: An Evolutionary Life History Perspective
This work sequenced the placental microbiome of preterm and full-term pregnancies, and related preterm/full-term variations in placental microbiome composition and function to maternal inflammation in order to evaluate the proximate roles of the placental microbiome in responding to maternal immune …
