When you're pregnant, there's a lot that can be detected in an ultrasound which can be helpful when it comes to the health of your baby.
Now, studies find that the size of a fetus during early pregnancy ... may determine that child's risk of developing asthma.
British researchers used ultrasound on two-thousand pregnant women to track fetal growth.
Children with a smaller fetal size during the first and second trimesters had an increased risk of asthma between the ages of five and 15.
On the other hand, larger fetuses were at a reduced risk of asthma ... and had better lung function.
More research is needed to see if fetuses who start small and stay small have the worst outcomes or whether it is those who start off normal size and then become small who are in trouble.
Getting M-R-I testing during the first trimester of pregnancy does not appear to harm a growing fetus.
A Canadian study looked over one million births over a 12 year period and found that having an M-R-I early in pregnancy did not increase the risk of stillbirth, birth defects, tumors, or hearing loss.
However, the use of an injected chemical to enhance the quality of m-r-i... called gadolinium (gad·o·lin·i·um)... is not recommended for pregnant women.
Gadolinium can increase the risk of several inflammatory and skin conditions in early childhood ... and possibly infant death.
And it's almost that time of year again when flu shots are needed... and infants whose mother's are vaccinated while they are pregnant are protected for up to two months of age.
Researchers followed a small group of pregnant women to determine how long the flu vaccine protected their babies against the virus.
They found that the vaccine worked best when the infants were eight weeks or younger and it wanes significantly after that.
And this is helpful since currently, babies are not able to get vaccinated themselves until they are six months of age.
