Estimating Causal Effects of Third‐Stage Management on Postpartum Haemorrhage in a Midwifery Context: An Evidence Synthesis Approach for Constructing Directed Acyclic Graphs

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Estimating the causal effect of third‐stage management approaches on preventing postpartum haemorrhage (PPH) in the context of physiologic birth using observational data requires conditioning on specific variables, with selection relying on assumptions about their roles in the exposure‐outcome pathway that are rarely made explicit ...

Perinatal clinical management of a rare ABh variant blood group

Transfusion Medicine, EarlyView.
Abstract Background The H antigen, precursor of the A and B blood groups, is a high‐prevalence antigen. Very few H antigen‐negative (H−) blood donors are available in the United Kingdom. Case Presentation We present the case of a second pregnancy in a 28‐year‐old woman with the very rare ABh phenotype, and the presence of anti‐H, anti‐A and anti‐B ...

Early exposure, enduring consequences: How do I manage Rh immunoglobulin prophylaxis after Rh‐mismatched transfusions in children?

Transfusion, EarlyView.
Abstract Background RhD mismatched transfusions in RhD negative women have the potential to impact future pregnancies through alloimmunization and development of hemolytic disease of the fetus and newborn (HDFN). As use of RhD positive emergency‐release blood products in pediatric trauma has increased, it has become clear that a significant ...

Placental insufficiency

Irish Journal of Medical Science, 1961
In summing up the few facts shown in this contribution, we may say that the clinical syndrome known as “placental insufficiency” or better, “nutritive placental hypofunction”, includes a primary type, presumably of genetic origin, which frequently leads to carly spontaneous abortion; and a secondary type which leads to the birth of an immature foetus ...

Placental insufficiency and postmaturity

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1975
Full placental development and functioning are achieved around the 5th month of gestation. Thereafter, until birth, signs of gradual placental aging are observed which are partly compensated by an increase in trophoblastic surface area to maintain adequate fetal oxygen and nutrient supply (Krantz and Kubli, 1967; Hellegers, 1969).

Placental insufficiency and its consequences

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2003
Placental insufficiency is a process leading to progressive deterioration in placental function and a decrease in transplacental transfer of oxygen and nutrients to the fetus. The resulting fetal hypoxemia is the major stimulus involved in the reduction in fetal growth as an attempt to reduce metabolic demands by the growing fetus.

Placental Gene Expression in a Rat ‘Model’ of Placental Insufficiency

Placenta, 2010
Placental insufficiency is a major factor associated with pregnancy complications such as miscarriages, intrauterine growth restriction and pre-eclampsia. Recent studies have identified the Brown Norway (BN) rat as a natural 'model' of placental insufficiency associated with decreased trophoblast remodeling of maternal uterine arteries.Genetic pathways
