BACKGROUND Sleep disturbances in late pregnancy are common. This study aimed to survey sleep problems in third trimester pregnant women and to compare sleep in the pre-pregnancy period with the third trimester. METHODS Third-trimester women (n=650) were sent a postal survey containing questions relating to sleep experience, including perceived sleep quality, sleep difficulties, night waking, ...

It has been assumed that sexual activity during pregnancy would lead to an increased risk for miscarriage and other complications of pregnancy. Various studies showed no association of sexual behavior and pregnancy complications in single pregnancies. The aim of our study was to evaluate changes in sexual activity in women with twin pregnancies and whether a higher frequency of sexual intercour...

Plasma concentrations of inhibin A and inhibin B during pregnancy and early lactation in chimpanzees were determined by enzyme-linked immunosorbent assay (ELISA). Plasma samples were taken from five pregnant chimpanzees at 6-9, 10, 20 and 25 weeks of pregnancy, and following parturition. Throughout pregnancy and the early postpartum period, circulating inhibin A and inhibin B concentrations rem...

Pregnancy and lactation are times of physiologic stress during which bone turnover is accelerated. Previous studies have demonstrated that there is increased mobilization of lead from the maternal skeleton at this time and that calcium supplementation may have a protective effect. Ten immigrants to Australia were provided with either calcium carbonate or a complex calcium supplement (approximat...

introduction as pregnancy progresses, nutrient requirements of fetus and thereby ewe increases and some changes in the levels of blood metabolites including glucose, cholesterol and total protein may occur. during gestation, maternal tissues contribute to supplying energy that required for fetus resulting in changes of ewe blood metabolites; however other factors such as breed, age, feeding typ...

introduction: brain abscess in pregnancy is very rare, which mostly progresses to neurological abnormalities. case presentation: the patient is a 24-year-old pregnant woman. she was referred to saitama hospital due to severe headache and nausea on october 2008. brain mri detected a 1.5 cm abscess mass with extensive edema in the right frontal lobe. we performed intensive therapy using some anti...

A critical development in the area of evidence synthesis occurred late 1980s with early work Ian Chalmers and colleagues on synthesizing related to pregnancy birth, culmi...

Normal pregnancy is associated with marked changes in cardiovascular haemodynamics, which in part may be due to changes in autonomic control mechanisms. Baroreflex sensitivity for heart rate (BRS) was calculated in the supine and standing positions using power spectral analysis of pulse interval (PI) and systolic blood pressure (SBP) in 16 normotensive pregnant women and 10 normotensive non-pre...

STUDY QUESTION How do human embryonic growth trajectories evolve in the first trimester, and is first-trimester embryonic growth associated with fetal growth and birthweight (BW)? SUMMARY ANSWER Human embryonic growth rates increase between 9 and 10 weeks of gestation and are associated with mid-pregnancy fetal growth and BW. WHAT IS KNOWN ALREADY Fetal growth is associated with health and ...

The maximal activity of phosphate-dependent glutaminase was increased in the small intestine, decreased in the liver and unchanged in the kidney of late-pregnant rats. This was accompanied by increases in the size of both the small intestine and the liver. The maximal activity of phosphate-dependent glutaminase was increased in both the small intestine and liver but unchanged in the kidney of p...
