Obstetrics. Gestational hypertension or pregnancy-induced hypertension (PIH) is the development of new hypertension in a pregnant woman after 20 weeks' gestation without the presence of protein in the urine or other signs of pre-eclampsia. [1] Gestational hypertension is defined as having a blood pressure greater than 140/90 on two occasions at ...
This terminology is preferred over the older but widely used term pregnancy-induced hypertension (PIH) because it is more precise. [10] The newer terminology reflects simply relation of pregnancy with either the onset or first detection of hypertension; the question of causation, while pathogenetically interesting, is not the important point ...
Pre-eclampsia is one of the leading causes of maternal and perinatal morbidity and mortality worldwide. [1] Nearly one-tenth of all maternal deaths in Africa and Asia and one-quarter in Latin America are associated with hypertensive diseases in pregnancy, a category that encompasses pre-eclampsia.

It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord, placental infarction, maternal diabetes (prepregnancy or gestational diabetes) [1] and maternal smoking.
Some degree of weight gain is expected during pregnancy. The enlarging uterus, growing fetus, placenta, amniotic fluid, normal increase in body fat, and increase in water retention all contribute weight gain during pregnancy. The amount of weight gain can vary from 5 pounds (2.3 kg) to over 100 pounds (45 kg).
The fetal origins hypothesis (differentiated from the Developmental Origins of Health and Disease hypothesis, which emphasizes environmental conditions both before and immediately after birth) proposes that the period of gestation has significant impacts on the developmental health and wellbeing outcomes for an individual ranging from infancy ...
The Proceedings of the Institution of Mechanical Engineers were first published by the Institution of Mechanical Engineers (IMechE) in 1847. [1] The Proceedings were published under this single title until 1963, when they began to be published in two parts. The Proceedings have since expanded further, in part by incorporating four journals ...
An artificial womb or artificial uterus is a device that would allow for extracorporeal pregnancy, [2] by growing a fetus outside the body of an organism that would normally carry the fetus to term.
