A study of pregnant women with MS found that those who breastfed exclusively had lower relapse rates than those who did not or stopped early. Women who delayed starting MS treatments to breastfeed also experienced faster return of menstrual periods.
The March of Dimes has awarded nearly $14 million in grants since 2009 to support innovative research on preterm birth. Researchers will investigate microbes, enzymes, and genetic factors to identify risk factors for prematurity and develop strategies to prevent it.
A study found that parents of children with genetic conditions are avoiding subsequent pregnancies instead of undergoing pre-natal testing or abortion. This 'ambivalent' response is rooted in a deep-seated concern about the limitations of new reproductive technologies and the risks involved.
A Michigan State University study found that providing home pregnancy tests to women who have unprotected sex can increase their vigilance about potential pregnancy and lead to better prenatal care. The intervention resulted in women suspecting they might be pregnant almost twice as often and having a pregnancy test more frequently.
A review and meta-analysis found that maternal obesity is associated with a significantly increased risk of congenital anomalies, including spina bifida, cardiovascular anomalies, and cleft palate. The absolute risk of these anomalies is estimated to be 0.47-0.61 per 1,000 births higher in obese women than in women of recommended BMI.
A new American Heart Association journal issue highlights unique risk factors among women and gender disparities in stroke care. Researchers found that women were less likely to receive perfect care, had a lower discharge rate, and received less aggressive treatment than men.
Researchers at M.D. Anderson Cancer Center found no difference in breast cancer survival rates for pregnant women compared to non-pregnant women, but those with Pregnancy Associated Breast Cancer (PABC) were more likely to be diagnosed late with advanced stages of the disease, leading to delayed treatment.
A new study published in Cancer found that pregnancy does not affect breast cancer severity or survival rates, but can delay diagnosis and treatment. Women who develop breast cancer while pregnant or shortly after have similar outcomes to those without a history of pregnancy.
Researchers developed a composite metric of maternal-drinking measures that can predict prenatal neurobehavioral dysfunction and deficits in children, identifying over 62% of mothers as drinking at risk levels. The metric was more successful than individual measures in predicting poor child cognition and behavior problems.
A Cardiff University research project found a link between prenatal smoking and anti-social behavior in children, but only when the mother was genetically linked to the child. The study suggests that factors other than smoking during pregnancy influence anti-social behavior.

The treatment showed no adverse effects during treatment or seven days after treatment, indicating its potential to prevent complications linked to the condition.
Researchers have discovered biomarkers in blood that could aid diagnosis of severe and debilitating forms of malaria, including placental and cerebral malaria. Elevated levels of C5a and angiopoietin-2 were found to be associated with these forms of the disease, potentially allowing for earlier detection and targeted treatment strategies.
Women exposed to secondhand smoke as adults or children are more likely to face fertility problems and suffer miscarriages, with a 68% increased chance of difficulty getting pregnant. The study analyzed data from over 4,800 non-smoking women and found that four out of five reported exposure to secondhand smoke during their lifetime.
Researchers at Boston University have found that consuming choline from eggs during pregnancy may affect breast cancer outcomes for a mother's offspring. The study suggests that genetic changes caused by prenatal choline exposure can impact tumor growth rates and survival rates.
Researchers at UCLA found that vitamin D stimulates cathelicidin production in placental tissues, enhancing antibacterial responses and protecting trophoblast cells from infection. The study suggests that pregnant women supplementing with vitamin D may enhance placental innate immunity.
A retrospective cohort study found maternal exposure to folic acid antagonists during pregnancy increases the risk of adverse outcomes such as preeclampsia and fetal growth restriction. The study recommends re-classifying some folic acid antagonists and increasing folic acid supplements for women taking these medications during pregnancy.
A three-country study found that women taking fluoxetine during pregnancy gave birth to four times as many babies with heart problems, while those taking paroxetine had three times higher levels. Smoking over ten cigarettes a day was associated with a five-fold increase in major heart problems.

Women exposed to hairspray at work during pregnancy have more than double the risk of having a son with hypospadias, according to a new Imperial College London study. Taking folic acid supplements in the first three months of pregnancy may reduce this risk by 36%.
Scientists have discovered that prostacyclin stimulates the activation of uterine muscles, leading to strong contractions during labor. This finding may help develop therapies for preventing preterm labor, a serious complication of pregnancy.
Researchers identified a potential new target for anticancer therapeutics by showing that well-oxygenated tumor cells use lactate as a fuel source, which is released by hypoxic tumor cells. Inhibiting this protein MCT1 disrupts the symbiotic relationship between tumor cell types and leads to decreased tumor growth in mice models.
A recent study published in Reproductive Health found that pregnant women who attended water aerobics classes had shorter labor durations and lower rates of analgesia requests compared to those who did not participate. The research suggests that moderate water aerobics during pregnancy may improve maternal and fetal health outcomes.
A review of bariatric surgery among women of reproductive age suggests that rates of adverse outcomes for mothers and newborns are lower after the procedure. Lower maternal complication rates were found in women who underwent bariatric surgery compared to those who were obese, with reduced rates of gestational diabetes and preeclampsia.
A new study found that women with diabetes have a seven times higher risk of severe pelvic girdle syndrome. Hormonal factors, such as relaxin, may play an important role in the development of the condition.
A study published in Human Reproduction found that placebo acupuncture resulted in a significantly higher overall pregnancy rate (55.1%) compared to real acupuncture (43.8%) in patients undergoing IVF. The researchers suggest that placebo acupuncture may have a real effect, contrary to its inert control status.
A high-fat diet during pregnancy produces permanent changes in the offspring's brain, leading to overeating and obesity early in life. The research found that rat pups born to mothers on a high-fat diet had more neurons producing orexigenic peptides, stimulating appetite and weight gain.
Women who have had two or more induced abortions have a 60% reduced risk of pre-eclampsia compared to those with no history. Physical activity during pregnancy shows some protection against pre-eclampsia, particularly among women under 25 BMI.
A recent study found that rural women are at increased risk of pre-eclampsia and pregnancy-induced hypertension, associated with maternal poverty and social deprivation. The researchers identified novel risk factors, including living in a rural area and having some college education, which were independent of other risk factors.
A study of 2025 women who donated kidneys found that female kidney donors do not face increased risks of miscarriage, premature birth or gestational diabetes. While post-donation pregnancies had higher rates of certain health conditions, these were comparable to those in the general population.
Chronic kidney disease exacts a significant toll on women's sexuality and gynecologic health, with hormonal changes affecting body functions. Experts will explore the impact of CKD on women's sexual life cycle, fertility, and pregnancy from adolescence through menopause.
Research found that mothers who smoked during pregnancy were more than twice as likely to have a baby with a cleft palate or lip. Nearly 7,000 babies are born annually with oral-facial clefts in the US, which can lead to feeding difficulties and other health issues.
