A large new study by Kaiser Permanente found no significant differences in health outcomes between pregnant patients receiving in-person or multimodal (virtual + in-office) prenatal care. Rates of complications like preeclampsia, severe maternal morbidity, and NICU admissions remained steady across time periods.
Researchers have discovered a way to identify pregnant women at risk of preeclampsia by examining lipids in their blood during pregnancy. The approach worked regardless of whether the women were on aspirin therapy, and could predict the risk of preeclampsia with significant accuracy.

Research from the University of Surrey and University of Birmingham finds detrimental effects of all severities of maternal dengue infections on birth outcomes, including increases in low, very low, and extremely low birth weights. Long-term consequences also include hospitalizations for children up to three years after birth.
A CU Anschutz study found that oral consumption of high doses of CBD during pregnancy impaired problem-solving skills in female mice. Fetal exposure to CBD also reduced the excitability of the pre-frontal cortex, a key area for learning.
Fetuses use a copy of a gene inherited from their dad to force their mum to release as much nutrients possible during pregnancy. This 'remote-control' system is operated by genes that can be switched on or off depending on whether they are a 'dad's' or 'mum's' gene.
Mothers with a criminal record and care experience face negative judgements and excessive scrutiny due to their 'known' status. The study emphasizes the need for supportive dialogue across disciplinary boundaries to break cycles of stigma and social care involvement, focusing on safe spaces and trust-building for care-experienced mothers.
A study published in Nature Communications found that infection rates in pregnant women attending antenatal care visits closely reflect the rates in children from cross-sectional studies, especially when molecular tests are used. This correlation can help estimate disease burden and inform control measures.

The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for anxiety disorders in older adults. Anxiety disorders are commonly occurring mental health conditions often unrecognized in primary care settings, leading to substantial delays in treatment initiation.
A new study led by UCL researchers found that at least one in five women conceived naturally after having a baby conceived with IVF. This figure remained unchanged even when considering different types and outcomes of fertility treatment. The study analyzed data from 11 studies involving over 5,000 women worldwide.

A new study found that pregnancy causes a shift in the types of immune cells present in a woman's blood, with neutrophils increasing dramatically. This discovery provides a 'normal reference' for studying immune changes during pregnancy and may have implications for understanding diseases such as rheumatoid arthritis.
A new study analyzed over six million births in England and found that being born 'out of hours' did not carry a significantly higher risk of death from anoxia or trauma. The study suggests focusing on reducing risks for emergency caesarean births without labour, rather than all out-of-hours births.
Research identifies beneficial changes in immune system during pregnancy, which can lead to new treatment strategies for MS. Women with MS experience a 70% decrease in relapses during the last third of pregnancy, possibly due to epigenetic changes and hormone regulation.

A recent study found that adolescents across various ages, genders, and geographies are aware of and concerned about the potential impacts of abortion restrictions. The study, led by Dr. Bianca A. Allison, used a nationwide text message poll to gather responses from over 800 adolescents between 14-24 years old.
A new American Heart Association scientific statement highlights the disproportionate burden of cardiovascular disease on AI/AN women. The study reveals that more than 60% of these women have suboptimal heart health when pregnant, increasing their risk of heart disease later in life.
A study from the University of Bergen reveals that women with a first normal weight offspring and a small second offspring have an increased risk of cardiovascular mortality. The research, published in the American Journal of Epidemiology, also found reduced risk if the second offspring was large.

The research found that mutations in the e-cadherin gene combined with exposure to inflammatory risk factors during pregnancy can lead to cleft lip, which affects one in 700 live births.
Research suggests that women living in low-income areas who move to higher-income areas experience lower morbidity and mortality rates in their second pregnancy, as well as improved outcomes for their newborns. Financial incentives or enhanced neighborhood factors may help reduce adverse maternal and perinatal outcomes.
Women who experience adverse pregnancy outcomes are at a higher risk of developing stroke, with those having recurrent issues facing a twofold increase. Lifestyle interventions and sharing pregnancy history with doctors may help reduce this risk, according to the study published in the journal Stroke.
A study of 1,050 pregnant women found frequent detection of HPV, with infrequent perinatal transmission. The authors note challenges in distinguishing contamination from true infection, particularly in placentas.

Continued exposure results in largest deficiencies, with newborns exposed to marijuana throughout gestation being nearly 200g lighter and having smaller head circumferences.
High levels of cortisol during the third trimester of pregnancy have been linked to improved speech and language skills in young children. Research found that boys exposed to high cortisol had better word-saying abilities, while girls showed enhanced understanding skills.
