A study found that pregnant women and new mothers in Cambodia use bear products to treat pregnancy and post-partum related ailments. This practice poses a significant threat to bear populations, highlighting the need for conservation efforts to reduce demand pressures.
A new study reveals that the immune system works differently between a woman's first and second pregnancy, with potential implications for preventing miscarriages and preterm births. The research found that the immune pathways promoting a healthy first pregnancy are distinct from those in later pregnancies.
Research found that vitrification technology is safe for embryos, but storing them for longer periods reduces chances of pregnancy and live birth. The study analyzed outcomes from 24,698 patients and found lower implantation, clinical pregnancy, and live birth rates with longer storage times.
A new University of Otago study found that mating with sterile males early in life increases female growth but reduces lifespan. Mating with fertile males later in life has the opposite effect, increasing reproductive output. The findings suggest long-term consequences of social interactions between males and females.
Researchers found that female mice mated with sterile male mice experienced a growth-reproduction trade-off, resulting in weight gain and increased reproductive output in late life. However, this also led to a reduced lifespan compared to those housed with other females.
A global study found broad support for alcohol warning labels in seven countries, including Australia (68%) and New Zealand (67%). The study suggests that governments should introduce clear and visible health warnings on alcohol products to improve public health.
A Columbia University study found that crowded homes and poor neighborhoods increase the risk of COVID-19 infection. Women living in high-density households were three times more likely to contract the virus.
A recent study published in BJOG: An International Journal of Obstetrics and Gynaecology found that COVID-19 transmission from mother to baby during pregnancy is rare.

A study by University of Queensland researchers found that maternal depression is linked to higher risks of behavioral problems and poor development in children. The study suggests that reducing depressive symptoms at any stage can improve outcomes for both mothers and children.
Pregnant patients with COVID-19 are often excluded from drug trials due to lack of fetal safety data. A new position paper suggests using electronic health record (EHR) data to simulate drug trials, identifying safer therapeutics for treatment. This approach could offer an alternative to delivering all pregnant patients with COVID-19.
Women with non-alcoholic fatty liver disease (NAFLD) in pregnancy face increased risks of maternal and infant health complications. The study found that NAFLD is associated with hypertensive complications, preterm birth, and maternal bleeding after delivery, independent of other metabolic diseases.
A national surveillance study found that more than half of pregnant women recently admitted to a UK hospital with COVID-19 infection were from black or other ethnic minority groups. Most women had good outcomes, but the high proportion of women from these groups warrants urgent investigation and explanation.
A study of nearly 1.7 million women found that benzodiazepine use before conception is associated with a 50% higher risk of ectopic pregnancies. This increases the risk of complications and infertility, highlighting the need for more research on safe treatment options.
Researchers found TSH testing performed on most pregnant women without thyroid disease, leading to unnecessary thyroid hormone therapy. The study suggests that minor elevations in TSH may not require treatment, raising concerns about overmedicalization during pregnancy.
A new study suggests that taking extra choline supplements during pregnancy may mitigate the negative impact of viral respiratory infections, including COVID-19, on fetal brain development. Higher prenatal choline levels have been shown to protect the fetus's developing brain from the effects of virus infection.
Researchers used MRI to investigate blood flow to the placenta in healthy and pre-eclampsia pregnancies, identifying differences in blood flow and a new phenomenon called the 'uteroplacental pump'. This finding could help explain why babies born to mothers with pre-eclampsia are often small and premature.
A study from Massachusetts General Hospital found significant racial and ethnic disparities in the use of medications for opioid use disorder during pregnancy. Black and Hispanic women were less likely to receive or consistently use these medications compared to white non-Hispanic women.
Researchers found that pregnancy reduces breast cancer risk by reprogramming breast cells to tuck away the potent cancer gene cMYC and keep them in a state of pre-senescence. This protective mechanism may provide new insights into future cancer treatment and help identify risk before tumors develop.
Researchers propose target trials to gather human drug exposure data for pregnant people, offering a basis for causal inference. Genomic data and organ-on-a-chip technologies will help validate results, making this a valid and ethical workflow for large-scale drug screening.
