These findings have significant implications for understanding the long-term effects of prenatal nutrition on health outcomes.
A new study reveals that severe kidney injury during pregnancy is rare, but affects otherwise healthy women who acquire a major complication. Babies born to mothers with severe kidney injury are at increased risk of low birth weight or premature birth.
A recent study published in The BMJ found that antipsychotic medication use during pregnancy does not significantly increase the risk of developing gestational diabetes, hypertensive disorders, or major blood clots. However, women who took antipsychotics were more likely to require labor induction compared to those who did not take them.
A recent study by the University of Helsinki found that early exposure to alcohol changes the way genes function in the brains of mice, influencing brain structure. The timing of the exposure corresponds to human gestational weeks 3-6, and similar changes were observed in other tissues of the infant mice.
Researchers have discovered a crucial gene, DNMT1, that maintains breast and cancer stem cells. High levels of DNMT1 expression are associated with increased risk of breast cancer, particularly in women over 30. Restoration of the opposing ISL1 gene significantly reduces stem cell populations and cancer growth.
A study published in The American Journal of Pathology found that bacterial and viral infections differentially influence placental transporter proteins, reducing their expression in early pregnancy. This decrease may expose the embryo/fetus to harmful substances during a critical time in development.
Researchers at Cold Spring Harbor Laboratory found that the mammary gland forms a long-term memory of pregnancy, allowing it to respond more efficiently to hormonal changes during subsequent pregnancies. This epigenetic memory is thought to explain why breastfeeding is easier in second and subsequent pregnancies.
