Researchers found that modulation of immune system during pregnancy is similar in women with and without lupus. In healthy pregnancies, key immune genes are quieted after embryo implantation, while those with preeclampsia or complications show downregulation of these genes.
A Norwegian study found that women under 30 have the lowest risk of miscarriage, while those over 45 face a 53% risk. Previous pregnancy complications also increase the risk, with pre-eclampsia not being a factor.
Women with severe influenza during pregnancy are more likely to have preterm birth and low birth weight infants. Pregnant women receiving the flu vaccine and those treated promptly with antiviral medications may reduce the risk of adverse infant outcomes.

The study involved 91 women who were divided into an exercise group or control group, with the exercise group experiencing a significant drop in diabetes rates and lower blood pressure.
A study found late preterm and early term birth rates decreased in the US between 2006 and 2014. Clinician-initiated obstetric interventions also declined, particularly among births over 37 weeks, suggesting a positive association with delayed interventions.
A 30-year study found that boys are more likely to experience pre-term birth, gestational diabetes, and pre-eclampsia, while girls face a higher risk of early onset pre-eclampsia. The research suggests sex differences in placental function may explain these disparities.
A Swedish study found that mothers who gained 4 kg/m2 or more between pregnancies had a higher risk of low Apgar scores, neonatal seizures, and meconium aspiration. Preventing weight gain could reduce birth asphyxia and improve infant health.
Elevated sFLT1 levels in mice predict preeclampsia-like symptoms, including increased angiotensin II sensitivity and decreased nitric oxide production. Treating preeclamptic mice with sildenafil reversed symptoms and improved fetal health.
The Society for Maternal-Fetal Medicine recommends the use of antenatal corticosteroids to improve outcomes for babies at risk of preterm birth in the late preterm period. The recommendations are based on a randomized trial that found significant benefits in reducing neonatal respiratory complications and other adverse outcomes.
A new study has identified pre-pregnancy heart abnormalities as a potential predictor of recurrent preeclampsia. Women who had early pregnancy-related high blood pressure were found to have abnormal changes in the size and function of their left ventricle, which pumps blood throughout the body.

A new Tel Aviv University study found that infants born past 42 weeks have twice the risk of contracting infections, experiencing respiratory difficulties, and being admitted to NICUs compared to those born at 39-40 weeks. This is the first time the isolated effect of post-term delivery on neonatal outcomes has been determined.
Researchers have developed a blood test to predict the development of preeclampsia, enabling early diagnosis and prevention of complications. The test measures the ratio of serum sFlt-1 to PlGF proteins, allowing for reliable prediction within one week.
A recent study published in CMAJ found that planned home births among low-risk pregnant women do not increase the risk of stillbirth, neonatal death, or serious events. In fact, these women were more likely to have spontaneous vaginal births and breastfeed exclusively after delivery.
A recent study published by Hospital for Special Surgery has identified complement activation as a strong predictor of adverse pregnancy outcomes in women with lupus. Elevated levels of Bb and sC5b-9 were found to be associated with an over 50% increase in the rate of pregnancy complications.
A new treatment involving the removal of a protein called sFlt-1 from the blood has shown promise in prolonging pregnancy in women with preeclampsia. Pregnancy continued for an average of 8 days and 15 days in treated women, compared to just 3 days in untreated women.
Researchers found that women with pre-eclampsia, pre-term delivery, and small-for-gestational-age delivery are at increased risk of CVD death. High blood pressure, glycosuria, and hemoglobin decline during pregnancy also predict CVD risk. Early detection and preventive care can help prevent heart disease deaths.
