The placenta’s hidden role in mental health
A groundbreaking finding challenges conventional understanding of stress responses during pregnancy that could potentially revolutionise our understanding of pregnancy-related anxiety and depression.
Professor Clifton, a maternal health expert professor at Mater Research Institute-University of Queensland, and her team, has identified 13 distinct glucocorticoid receptor isoforms in the placenta, with one particular variant showing a surprising response to maternal stress.
“We have discovered that the placenta has 13 different isoforms of the glucocorticoid receptor, with one isoform expressed in the presence of maternal stress, anxiety, and depression that activates an inflammatory response in the placenta in the presence of high cortisol concentrations,” Professor Clifton explains.
While most glucocorticoid receptors typically suppress inflammation, this newly identified variant appears to enhance it, potentially explaining the complex relationship between stress and inflammation in pregnant women.
Sex-specific medicine: A new frontier
Professor Clifton’s research has unveiled crucial differences between male and female foetuses, mediated through sex-specific placental functions.
“Presently, we do not consider the sex of the foetus in Obstetrics,” she notes. “I would like to see sex-specific medicine for pregnancy complications, for the care of preterm neonates, and for the care of newborns.”
Her work suggests that maternal physiology varies depending on foetal sex, opening new possibilities for personalised interventions in pregnancy care. This insight could transform how clinicians approach pregnancy complications and neonatal care.
From personal experience to scientific innovation
The interview reveals how personal tragedy shaped Professor Clifton’s research focus. Following the loss of her son in mid-gestation, she was driven to understand “What went wrong?”.
This experience led her to study placental function and its regulation by stress hormones, eventually establishing Australia’s largest birth cohort study at Mater Research Institute.
Professor Clifton’s team is investigating how placental inflammation might influence maternal brain function, potentially exacerbating anxiety and depression symptoms during pregnancy. This research could revolutionise our approach to perinatal mental health care and lead to targeted interventions based on placental function.
Mira has launched an at-home cortisol tracking kit that allows women to monitor stress-related patterns over time using urine samples.
The Cortisol Pattern Kit measures urinary free cortisol directly from a urine sample and displays results through the company’s existing monitor and app.
The system is intended for repeated testing rather than a single measurement, allowing users to compare results with a personal baseline built from their own data.
Mira said consistent daily testing can establish a baseline in about a week. It recommends testing in the morning and evening to see how cortisol patterns change throughout the day.
Cortisol is involved in the body’s stress response but is not a direct or complete measure of stress. The company said the kit is intended for general wellness use and is not designed to diagnose stress, an endocrine condition or any other medical condition.
The Cortisol Pattern Wands use the same lateral-flow testing format as Mira’s existing hormone tests. Users dip a wand into a urine sample, insert it into the Mira Monitor and view the result in the app within minutes.
The company said cortisol data can be viewed alongside cycle, hormone and daily routine information.
Sylvia Kang, founder and chief executive of Mira, said: “The Cortisol Pattern™ Kit gives women a new way to understand their stress patterns over time, in the context of their own biology.”
She added: “We built Mira to give women answers they had spent far too long searching for, beginning with the TTC journey and expanding into hormone and cycle tracking across life stages, including perimenopause. Now, we’re taking Mira beyond reproductive health and into everyday wellness, bringing personalised stress-pattern tracking directly into women’s homes.”
Mira said more than 350,000 women already use its platform to track their cycle and hormones.
Waitlist sign-ups for the Cortisol Pattern Kit and Cortisol Pattern Wands opened on 22 September, with wand refills available to pre-order in 20- and 30-count options.
Manchester City has launched a female athlete health platform covering menstrual, pelvic and breast health, as well as nutrition.
The Her City website is designed for the club’s women’s first-team players, coaches, support staff, academy players and parents.
Manchester City says the platform is the first of its kind in the Women’s Super League and was developed over two years.
The project was led by director of performance services Emma Deakin, physical performance scientist Rosie Anderson and PhD student and first-team nutritionist Sarah Malone.
It grew out of PhD research into menstrual, pelvic and breast health and nutrition, with the team seeking to turn that work into an online educational resource.
The website divides the four areas into separate sections and provides peer-reviewed information that the club says has been critically analysed by experts.
Content will continue to be reviewed and updated as further evidence emerges.
Resources include posters, visual explainers, audio materials and downloadable educational content, with information tailored to different groups including players and parents.
The platform aims to improve knowledge, develop critical analysis skills and strengthen communication within football and at home.
It also includes material to help users assess misinformation they encounter on social media or elsewhere.
A confidential contact form allows users to raise concerns or ask questions directly of experts at Manchester City.
Parents of academy players can also access the platform, with resources intended to help them support their children during a key phase of their development.
Manchester City said its longer-term aim is to make the platform available to all women working across City Football Group.
Small bowel microbiome differences between women and men may help explain why some conditions are more common in women, a study suggests.
The small bowel microbiome is the community of microorganisms living in this part of the digestive tract, where they play vital roles in immune function, metabolism and hormonal regulation.
Researchers found differences between women and men in the composition and organisation of these microbial communities. One bacterial community containing Granulicatella was found only in women.
The study was conducted by investigators at Cedars-Sinai Health Sciences University.
Ruchi Mathur, director of clinical research and clinical operations for the Medically Associated Science and Technology (MAST) Program at Cedars-Sinai and corresponding author of the study, said: “One intriguing finding was a bacterial community containing Granulicatella, which we found only in women.
“Bacteria in this community appear at increased levels in women with polyendocrine metabolic ovarian syndrome, formerly known as polycystic ovary syndrome.”
The researchers also identified differences between women and men in how microbes in the small bowel produce fructans, complex carbohydrates known to trigger digestive symptoms in irritable bowel syndrome (IBS).
IBS is far more common in women than men.
Mathur, who is also a professor of medicine, said: “Our findings show that biological sex is a critical variable in the small bowel microbiome.
“We must consider it as we move toward more personalised approaches to understanding and treating disease.”
