The research uses artificial intelligence techniques to analyze fetal blood flow and predicts the development of respiratory health problems later in life.
Researchers are studying the early brain development of babies born to mothers with diabetes to understand the link between prenatal exposure and later childhood obesity. They aim to identify key differences in brain structure and function that may contribute to the increased risk of obesity.
The guideline provides recommendations on the effects of antiseizure medications and folic acid supplementation on malformations at birth and child development during pregnancy. It recommends minimizing tonic-clonic seizures and using medications like lamotrigine, levetiracetam, or oxcarbazepine to minimize risk of major birth defects.

Higher cortisol levels in the womb may lower a boy's IQ score at age 7, while higher urine cortisone levels may improve a girl's IQ score. Research suggests that prenatal exposure to cortisol affects cognitive function in children independently of sex.
A new study reveals a common chromosomal microdeletion, 22q11.2del, as the first identified genetic variation contributing to spina bifida. The deletion is associated with a risk of spina bifida more than 10 times greater than the general public. Folic acid supplementation may also help reduce this risk and severity.
Despite concerns about data privacy risks in the post-Roe era, many American women continue to use popular period-tracking apps without taking steps to protect their information. The study found that users are unsure how to take control of their data and feel in the dark about how it is used and shared on these apps.
A study published in JAMA Network Open found that combining cannabis and nicotine use during pregnancy significantly increases the risk of poor health outcomes for newborns. Infants born to mothers using both substances are at a fourfold higher risk of infant death compared to those using neither substance. Abstaining from at least one...
The Healthy Start scheme in England is a vital support for pregnant women and low-income families, but uptake remains suboptimal. A new study recommends reframing the scheme as a child's right to good food and healthy development, improving coordination and resources.
A multisite review found that adverse events during outpatient care were relatively common and often serious, with 7% of outpatients experiencing at least one event. Adverse drug events were the most common, and these events occurred more frequently among older adults and were often preventable.
