Effective prevention strategies targeting vulnerable populations, such as pregnant women and road users, are necessary.
Researchers found that Dot had a typical-use failure rate of 5 percent and a perfect-use failure rate of 1 percent, comparable to other fertility awareness-based methods. The study also found no association between pregnancy and sociodemographic characteristics.
A study of nearly 500,000 women found that taking paracetamol or other painkillers during pregnancy increases the risk of asthma in children, but the risk is similar when other types of painkillers are used. The research suggests that another factor linked to painkiller use and asthma risk may be chronic pain and stress.
A study led by the University of Colorado found that choline supplements can prevent fetal brain developmental problems when a mother has the flu during pregnancy. Higher levels of choline in mothers also improved their children's ability to pay attention and regulate their behavior.
