One in three pregnant women in Norway has a vitamin D deficiency at the end of her pregnancy, a major study published earlier this year in PLOS One has shown.
Pregnant women with type 1 diabetes run a higher risk of having babies with heart defects, especially women with high blood glucose levels during early pregnancy, a study from Karolinska Institutet and the Sahlgrenska Academy in Sweden published in The BMJ shows.
For a pregnancy to proceed to term, early modulation of the immunologic response is required to induce tolerance to the fetus. Growing evidence suggests that vitamin D deficiency may affect this process and may play a part in recurrent pregnancy loss.
New research presented at this year's Euroanaesthesia congress in Copenhagen, Denmark, shows that giving women different types of virtual reality (VR) sessions prior to sedation for IVF treatment (to become pregnant) reduces their anxiety and could improve successful pregnancy rate. The study is by Professor Fabienne Roelants, Saint-Luc Hospital, Catholic University of Louvain, Brussels, Belgium, and colleagues.
A study published in the BMJ Open journal shows that even moderate coffee consumption during pregnancy, one to two cups per day, is related to a risk of overweight or obesity in school age children. It has not been clearly shown if caffeine is the direct cause of the overweight, but the relationship, alone, has caused researchers to encourage increased caution.
In the last trimester of a pregnancy, a woman can develop high blood pressure and undesirable excretion of protein in the urine. If these symptoms of so-called pre-eclampsia are not treated, the condition could become life-threatening to both mother and baby.
