It remains unclear whether screening for asymptomatic bacteriuria in pregnant women causes more benefit or harm. The results of studies from the 1960s are not applicable to the current situation, reviewers say.
The mechanism by which embryos receive nutrition during the first 11 weeks of pregnancy has been revealed by scientists. The new study explains some of how this crucial stage of development operates, suggesting not just that a healthy diet during the first 11 weeks of pregnancy is essential, but that as nutrients are stored in the gland cells before pregnancy, it is also important to get this right before conception.
Children born to mothers experiencing economic hardship, who were also exposed during pregnancy to high levels of PAH (polycyclic aromatic hydrocarbons), scored significantly lower on IQ tests at age 5 compared with children born to mothers with greater economic security and less exposure to the pollutants.
Preventing preterm labor with light and inducing labor using a side effect-free drug are two new technologies based research that is heading to the marketplace.
New research has discovered a link between a vital pumping system that does not function correctly in people with cystic fibrosis and the parasite Toxoplasma. This is the first time a causal relationship has been proven between infection of the Toxoplasma gondii infection and a defect in the chloride pumping system being linked to diseases such as cystic fibrosis. The new knowledge from these research findings paves the way for the development of new drugs to treat respiratory diseases.
Although obstructive sleep apnea (OSA) is less common in young women, sleep apnea was found in 4.9 percent in a cohort of pregnant women. In addition, OSA worsens as pregnancy progresses and is likely to persist into the early postpartum period. An elevated upper body position might improve respiratory safety in women early after childbirth without impairing sleep quality, a new study concludes.
Exposure to high levels of pollution can have a significant impact on fetal growth and development, researchers conclude. Their study found that women who were pregnant during the 2008 Beijing Olympics, when pollution levels were reduced by the Chinese government, gave birth to children with higher birth weights compared to those who were pregnant before and after the games.
A new study from Loyola University Medical Center provides further evidence that female infants tend to do better than males when born prematurely. The study found that female infants independently orally fed one day earlier than males. The ability to suck, swallow and breathe simultaneously are reflexes that many premature infants are unable to do. Learning to master these skills and eat independently without feeding tubes is necessary before an infant can safely go home from the hospital.
Researchers have identified a number of genes that contribute to large offspring syndrome, which can result in the overgrowth of fetuses and enlarged babies. In humans, this disorder is called Beckwith-Wiedemann syndrome (BWS).
Scientists have developed a technique to more effectively grow and screen embryos prior to implantation.
