Study identifies multi-organ response to seven days without food      (via sciencedaily.com)     Original source 

New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.

New study links placental oxygen levels to fetal brain development      (via sciencedaily.com)     Original source 

A new study shows oxygenation levels in the placenta, formed during the last three months of fetal development, are an important predictor of cortical growth (development of the outermost layer of the brain or cerebral cortex) and is likely a predictor of childhood cognition and behavior.

Intervention reduces likelihood of developing postpartum anxiety and depression by more than 70%      (via sciencedaily.com)     Original source 

Results from a large clinical trial show that an intervention for anxiety provided to pregnant women living in Pakistan significantly reduced the likelihood of the women developing moderate-to-severe anxiety, depression, or both six weeks after birth.

Study of 1.2+M births reveals associations between excess heat exposure and preterm births      (via sciencedaily.com)     Original source 

In the face of increasing temperatures globally, a new study of 1.2 million births over two decades has shown a strong association between the risk of pre-term birth and exposure to extreme hot temperatures in the third trimester of pregnancy. The data suggested that this association with extreme temperature might be reduced by the level of greenery in a pregnant person's residential surrounds. The findings suggest health services should consider preparing for an increase in preterm births as our climate warms.

Oocytes outsmart toxic proteins to preserve long-term female fertility      (via sciencedaily.com)     Original source 

The accumulation of misfolded or damaged proteins in long-lived, non-dividing cells like neurons are linked to neurodegenerative diseases like Alzheimer's. A study now finds that the build-up of these toxic proteins also influences oocyte quality and female fertility. The researchers discovered that mouse oocytes have specialized structures which roam the cytoplasm and act like a clean-up crew which capture and hold onto protein aggregates, rendering them harmless. Failure to degrade the toxic proteins led to the formation of defective eggs. 3 in 5 (60%) of mouse embryos that inherited the toxic proteins failed to complete the very earlies stages of development. The study presents a new frontier to explore the underlying mechanisms of poor oocyte quality, which is the leading cause of female infertility.

Scientists discover new target for reversible, non-hormonal male birth control      (via sciencedaily.com)     Original source 

Scientists discovered a new target for reversible, non-hormonal male birth control. The drug, an HDAC inhibitor, blocked sperm production and fertility in male mice without affecting libido or future reproduction.

Stress during pregnancy can lead to early maturation of first-born daughters      (via sciencedaily.com)     Original source 

Researchers have found a correlation between early signs of adrenal puberty in first-born daughters and their mothers' having experienced high levels of prenatal stress. They did not find the same result in boys or daughters who were not first-born.

Women get the same exercise benefits as men, but with less effort      (via sciencedaily.com)     Original source 

A new study shows there is a gender gap between women and men when it comes to exercise. The findings show that women can exercise less often than men, yet receive greater cardiovascular gains.

New study analyzes link between digit ratio and oxygen consumption in footballers      (via sciencedaily.com)     Original source 

The efficiency of oxygen supply to tissues is a factor in the severity of important diseases such as Covid-19 and heart conditions. Scientists already know that the relationship between the length of a person's index and ring fingers, known as the 2D:4D ratio is correlated with performance in distance running, age at heart attack and severity of Covid-19.

School uniform policies linked to students getting less exercise, study finds      (via sciencedaily.com)     Original source 

School uniforms could be restricting young people from being active, particularly primary school-aged girls, according to a new study. The study used data about the physical activity of more than a million five-to-17-year-olds in 135 countries. In countries where a majority of schools require students to wear uniforms, fewer young people are meeting the World Health Organization's recommendations for physical activity (60 minutes per day). Fewer girls are meeting the guidelines than boys -- with a standard gap of 7.6 percentage points between boys and girls.

COVID-19 vaccination and boosting during pregnancy protects infants for six months, study finds      (via sciencedaily.com)     Original source 

Women who receive an mRNA-based COVID-19 vaccination or booster during pregnancy can provide their infants with strong protection against symptomatic COVID-19 infection for at least six months after birth, according to a new study. These findings reinforce the importance of receiving both a COVID-19 vaccine and booster during pregnancy to ensure that infants are born with robust protection that lasts until they are old enough to be vaccinated.

Heart organoids simulate pregestational diabetes-induced congenital heart disease      (via sciencedaily.com)     Original source 

An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that endoplasmic reticulum (ER) stress and lipid imbalance are critical factors contributing to these disorders, which could be ameliorated with exposure to omega-3s.

Pregnant women should avoid ultraprocessed, fast foods, experts urge      (via sciencedaily.com)     Original source 

Research shows that phthalates, a class of chemicals associated with plastics, can shed from the wrapping, packaging and even from plastic gloves worn by food handlers into food. Once consumed during pregnancy, the chemicals can get into the bloodstream, through the placenta and then into the fetal bloodstream. The chemical can cause oxidative stress and an inflammatory cascade within the fetus, researchers noted. Previous literature has indicated that exposure to phthalates during pregnancy can increase the risk of low birth weight, preterm birth and child mental health conditions such as autism and ADHD.
