A Canadian study of over 100,000 children born to vaccinated mothers during the 2009 H1N1 pandemic found no association with increased risk of health problems. However, some slight associations were observed for gastrointestinal infections and asthma, but these were small and may be due to confounding factors.
A new study found that a high-fiber diet during pregnancy can reduce the risk of preeclampsia by promoting a healthy immune system in the developing fetus. The research also suggests that low levels of acetate, a key metabolic product of gut bacteria, may be associated with preeclampsia.
Pregnancy outcomes for lupus patients have dramatically improved, with a decline in maternal and fetal mortality rates over the past two decades. The study found that more women with lupus are attempting pregnancy and delivering successfully, with minimal risk of complications.

Research examining US alcohol and pregnancy policies from 1972-2015 found varying effects on birth outcomes by race. For White women, most policies had adverse effects, while for Black women, four policies had beneficial effects. The study suggests future research should explore the reasons behind these disparities.
The Mexico City Policy is associated with a 40% increase in abortions and a decrease in modern contraceptive use among women in sub-Saharan Africa. The policy's restriction on funding to abortion-giving organizations likely contributed to the rise in abortions, as it reduced access to modern contraception.

Researchers found that VEGF treatment increased uterine artery remodeling and improved blood flow to the placenta.
A UK study published in Diabetologia found that obesity during pregnancy is associated with a 3.5 times increased risk of type 2 diabetes in the child, while being overweight increases this risk by 40%. The study suggests strategies to reduce obesity and overweight in women of reproductive age are urgently needed.
Hepatitis C virus (HCV) transmission from mothers to babies can be largely prevented with universal HCV screening in pregnancy. Almost half of women infected with HCV are unaware of their infection, highlighting the need for increased awareness and early detection.
A new non-invasive prenatal test has been developed to diagnose sickle cell disease in unborn babies. The test uses cell-free fetal DNA and has shown promising results, with successful diagnoses achieved in 21 out of 24 pregnancies. Further development and validation are needed before the test can be introduced into clinical practice.
A new study from the University of Exeter found that married American moms are more likely to try to time their pregnancy for a spring birth, with factors such as age, education, and marital status influencing this decision. On average, a married woman aged 20-45 would be willing to pay $877 USD to guarantee a spring birth.
Researchers found that a pregnant woman's sense of personal space expands only during the third trimester of pregnancy. This expansion is believed to be an adjustment made by the brain to protect the vulnerable abdomen from daily interactions.
Researchers at Arizona State University have developed a new hypothesis to explain the phenomenon of women being more prone to autoimmune diseases like multiple sclerosis and lupus. The Pregnancy Compensation Hypothesis suggests that women's immune systems evolved to facilitate survival during pregnancy, leading to heightened immune su...

The proposed program would involve collaboration among clinical experts, front-line providers, and health organizations to ensure responsible conduct and independence from industry.
A new study reveals that women undergoing fertility treatment are at a higher risk of peripartum cardiomyopathy (PPCM), a life-threatening condition. PPCM affects about one in 1,000 pregnant women worldwide and is characterized by an enlarged and weak heart, leading to symptoms such as shortness of breath and swelling.
