A population-based study found that long-term smoking is associated with a 30-40% increased risk of breast cancer, particularly among women who start smoking before their first full-term pregnancy. The study also suggests that combined hormone therapy increases breast-cancer risk in women who smoke long term.
A Canadian study found that severe maternal morbidity rates declined between 1991 and 2001, with lower rates of postpartum hemorrhage requiring transfusion. However, a significant increase in uterine rupture cases was observed during this period, with women who experienced these complications being 158 times more likely to die.
Researchers are studying a vaccine that may eliminate the risk of group B streptococcus infection in newborns, which is responsible for 1,720 annual infections and 70-90 deaths. The vaccine aims to reduce the risk by eliminating the bacteria from the vagina before birth.
A study found that fetal alcohol exposure can alter the dopamine system in monkeys, affecting cognition and behavior. The timing of exposure during gestation varies the impact, with early exposure blunting the system and later exposure leading to supersensitive receptors.
A study of 1,001 women found that oral contraceptive users had a 40% lower incidence of multiple sclerosis compared to non-users. Pregnancy also showed a lower risk, while the postpartum period increased the risk of MS onset. Estrogen levels may play a role in these findings.
