A new imaging technique to track maternal blood flow to the placenta has the potential to help diagnose several common complications in early pregnancy, according to a study funded by the National Institutes of Health. Researchers used the technique, referred to as pseudo-continuous arterial spin labeling magnetic resonance imaging (pCASL MRI), to identify women with reduced placental blood flow who later developed one or more complications.

Exposure to acetaminophen in the womb may increase a child’s risk for attention deficit/hyperactivity disorder and autism spectrum disorder, suggests a study funded by the National Institutes of Health and the Agency for Health Care Research and Quality.

Exposure to high levels of certain common air pollutants in early pregnancy may increase the risk of pregnancy-induced high blood pressure, suggests an analysis by researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. In addition, exposure to a class of air pollutants known as volatile organic compounds in mid-pregnancy may increase the risk for preeclampsia, a potentially fatal disorder of pregnancy affecting blood pressure and kidney function.

Children born to women on HIV therapy containing the drug dolutegravir since conception have a slightly higher risk of neural tube defects, compared to children born to women on regimens of other antiretroviral drugs.

Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the National Institutes of Health.

Low vitamin D levels at birth or in early childhood may increase the risk of high blood pressure in later childhood or adolescence, suggests a study funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development and the Health Resources and Services Administration.
