Racial and ethnic disparities in severe maternal morbidity — life-threatening maternal complications associated with childbirth — have persisted and increased at high rates among U.S. women, according to an analysis of nearly 20 years of California hospital records funded by the National Institutes of Health. Known risk factors for these complications — such as blood

The complex sugars found in human breastmilk, long believed to be fixed in their composition, may change in women who are taking probiotics, according to new research from the University of Rochester Medical Center (URMC). The finding, published in a research letter in JAMA Pediatrics, upends what scientists thought of human milk oligosaccharides (HMOs) —

Medical researchers at Melbourne’s Murdoch Children’s Research Institute have made a new discovery about how a baby’s sex is determined — it’s not just about the X-Y chromosomes, but involves a ‘regulator’ that increases or decreases the activity of genes which decide if we become male or female. The study, ‘Human Sex Reversal is caused

Ninety-one nations are not producing enough children to maintain their current populations, while the opposite is true in 104 countries where high birth rates are driving population increases, according to a new scientific study. Total fertility rates (TFR), a summary measurement representing the average number of children a woman would deliver over her lifetime, have

Excessive stress during fetal development or early childhood can have long-term consequences for the brain, from increasing the likelihood of brain disorders and affecting an individual’s response to stress as an adult to changing the nutrients a mother may pass on to her babies in the womb. The new research suggests novel approaches to combat

The discovery of a 10-year-old’s body at an ancient Roman site in Italy suggests measures were taken to prevent the child, possibly infected with malaria, from rising from the dead and spreading disease to the living. The skeletal remains, uncovered by archaeologists from the University of Arizona and Stanford University, along with archaeologists from Italy,

Preterm birth remains a global epidemic linked to a lifetime of potential health complications. It also is difficult to study in living creatures — especially the uniquely precise biology of preterm birth in humans. Researchers report in PLoS Biology successfully inserting just enough human DNA into transgenic laboratory mice that it allowed the team to

Obese mothers who lose weight through bariatric surgery can have safer deliveries. The positive effects are many, including fewer caesarean sections, infections, tears and haemorrhages, and fewer cases of post-term delivery or uterine inertia. This according to an observational study by researchers at Karolinska Institutet in Sweden published in PLOS Medicine. Today, more than one

Evidence of tiny particles of carbon, typically created by burning fossil fuels, has been found in placentas for the first time, in new research presented today (Sunday) at the European Respiratory Society International Congress. Previous research has indicated links between pregnant mothers’ exposure to air pollution and premature birth, low birth weight, infant mortality and

The amount of physical activity that women undertake is not linked to their risk of early menopause, according to the largest study ever to investigate this question. Until now, there have been conflicting findings about the relation between physical activity and menopause, with some studies suggesting that women who are very physically active may be

The world’s first baby born via in-vitro fertilization turned 40 years old this summer. Still, after four decades, IVF is a relatively new field with ongoing debate on how to get the best results for families who have placed their hopes — and often their personal savings — into fertility treatment. IVF experts disagree about

Lipid droplets: they were long thought of merely as the formless blobs of fat out of which spare tires and muffin tops were made. But these days, they’re “a really hot area of research,” says Michael Welte, professor and chair of biology at the University of Rochester. That’s in part because lipid droplets have been

Pregnant women who had low plasma levels of long chain n-3 fatty acids in their first and second trimesters were at a significantly higher risk of early preterm birth when compared with women who had higher levels of these fatty acids, according to new research from Harvard T.H. Chan School of Public Health in collaboration

The cerebral cortex is a highly developed brain region, which allows intellectual functions such as conscious perception, anticipation of events and language. These functions are mediated by specific sets of neuronal circuits. To understand how these circuits emerge during development, researchers from the University of Geneva (UNIGE), Switzerland, in collaboration with an American team, investigated

Nicotine exposure during pregnancy, whether from smoking cigarettes, or nicotine patches and e-cigarettes, increases risk of sudden infant death syndrome — sometimes known as “cot death” — according to new research published in the Journal of Physiology. Sudden infant death syndrome (SIDS) is the sudden and unexpected death of an infant under 12 months of

A research team found a novel function of fibroblast growth factor 2 (FGF2), a self-renewal factor for spermatogonial stem cell (SSC) which is the origin of the sperm production. Although it has demonstrated that both FGF2 and glial cell line-derived neurotrophic factor (GDNF) is indispensable for SSC self-renewal and survival in vitro, the present study

Contrary to common suggestion, women are opting to freeze their eggs not to pursue education or careers but for reasons “mostly revolving around women’s lack of stable partnerships with men committed to marriage and parenting.” This is the conclusion of the largest qualitative study so far in elective egg freezing; 150 subjects from four IVF

Patients don’t mind if their emergency care doctors sport tattoos or piercings, or both, suggests an observational study published online in Emergency Medicine Journal. Evidence of visible body art seems to have no discernible impact on what they think of their doctor’s professionalism or competence, the findings show. Previous research on patient attitudes towards doctors’

Pregnancy loss and the death of a newborn baby are devastating events, and as of today around 25% of these perinatal deaths are unexplained despite autopsy. Discovering the cause of such a loss is of great importance for the bereaved parents, both in providing an explanation and in helping them to understand the likelihood of

Hiding in plain sight, new research shines a spotlight on the placenta’s critical role in the nature versus nurture debate and how it confers risk for schizophrenia and likely other neurodevelopmental disorders including ADHD, autism, and Tourette syndrome. This new scientific frontier, with far-reaching implications for maternal and child health, creates the possibility that scientists
