TOPLINE:

Gestational supplementation of 1000 IU/d cholecalciferol (vitamin D3) from early pregnancy until delivery increases the bone mineral content, bone mineral density (BMD), and bone mineral apparent density in children at age 6-7 years.

METHODOLOGY:

• The double-blinded, placebo-controlled MAVIDOS trial of gestational vitamin D supplementation previously showed increased BMD at age 4 years (but no difference at birth), and it is unclear how the effect may persist or change over time.
• In the original trial, researchers randomized 1134 pregnant women with singleton pregnancy from three UK hospitals from 2008 to 2014, and the 723 children born to mothers recruited in Southampton were invited to continue in offspring follow-up.
• Mothers were randomly assigned to receive either 1000-IU/d vitamin D or placebo from 14-17 weeks’ gestation until delivery; women in the placebo arm could take up to 400-IU/d vitamin D.
• In this post hoc analysis, among 454 children who were followed up at age 6-7 years, 447 had a usable whole body and lumbar spine dual-energy x-ray absorptiometry scan (placebo group: n = 216; 48% boys; 98% White mothers and vitamin D group: n = 231; 56% boys; 96% White mothers).
• Offspring follow-up measures at birth and 4 and 6-7 years were bone area, bone mineral content, BMD, and bone mineral apparent density, derived from a dual-energy x-ray absorptiometry scan of whole body less head (WBLH), as well as fat and lean mass.

TAKEAWAY:

• The effect of gestational vitamin D supplementation on bone outcomes in children was similar at ages 4 and 6-7 years.
• At age 6-7 years, gestational vitamin D supplementation resulted in higher WBLH bone mineral content (0.15 SD; 95% CI, 0.04-0.26) and BMD (0.18 SD; 95% CI, 0.06-0.31) than placebo.
• The WBLH bone mineral apparent density (0.18 SD; 95% CI, 0.04-0.32) was also higher in the vitamin D group.
• The lean mass was greater in the vitamin D group (0.09 SD; 95% CI, 0.00-0.17) than in the placebo group.

IN PRACTICE:

“These findings suggest that pregnancy vitamin D supplementation may be an important population health strategy to improve bone health,” the authors wrote.

This study was led by Rebecca J. Moon, PhD, MRC Lifecourse Epidemiology Centre, University of Southampton, Southampton General Hospital, England. It was published online in The American Journal of Clinical Nutrition.

LIMITATIONS: 

Only individuals with baseline vitamin D levels of 25-100 nmol/L were eligible, excluding those with severe deficiency who might have benefited the most from supplementation. The participants were mostly White and well-educated, commonly overweight, which may have limited generalizability to other populations. Only 47% of the original cohort participated in the follow-up phase. Differences in maternal age, smoking status, and education between participants who remained in the study and those who did not may have introduced bias and affected generalizability.

Breast cancer incidence has been on the rise, particularly among White women under age 50, but breast cancer deaths — for some, but not all, populations — have been steadily decreasing, according to a biennial update from the American Cancer Society (ACS).

The ACS update, which underscores the persistence of racial and ethnic disparities in breast cancer incidence and outcomes, noted an overall 1% annual increase in breast cancer incidence from 2012 to 2021. The additional cases were largely composed of localized-stage and hormone receptor (HR)–positive disease, which generally have better prognoses than more advanced and HR–negative disease.

Deaths from breast cancer, however, declined from 1989 to 2022, with an overall drop of 44%. That percentage drop “translates to almost 518,000 fewer women dying from breast cancer in the United States during this time,” Angela N. Giaquinto and ACS colleagues noted in the report, published in CA: A Cancer Journal for Clinicians.

“This progress is the result of advances in treatment and earlier detection through screening,” the authors wrote, while stressing that “these interventions have not been disseminated equally.”

The ACS also published an educational companion — Breast Cancer Facts & Figures 2024-2025 — that provides additional insights about trends in breast cancer and steps needed to bolster prevention, detection, and treatment advances.
 

Incidence and Mortality

Although the overall annual increase in breast cancer incidence from 2012 to 2021 was 1%, the increase was steeper among women under age 50, at 1.4% annually vs 0.7% among those aged 50 or older.

Asian American/Pacific Islander women had the greatest increases in breast cancer incidence among both age groups, with a 2.7% annual increase for those aged under 50 and a 2.5% increase for those aged 50 or older. This group, however, had the second lowest breast cancer rate in 2000 at 57.4 cases per 100,000 persons, but the highest rate in 2021 at 86.3 cases per 100,000, alongside White women (86.4 cases per 100,000). Black women were not far behind at 81.5 cases per 100,000.

Black women were least likely to be diagnosed with localized-stage breast cancer and most likely to be diagnosed with distant-stage or unstaged cancer, with American Indian/Alaska Native women not far behind.

Despite the rising incidence of breast cancer, death rates from the disease have gone down considerably overall from about 33 deaths per 100,000 women in 1989 to 19 deaths per 100,000 in 2022.

However, not all women have experienced these survival gains equally, Ms. Giaquinto and colleagues noted.

Since 1990, the mortality rate has remained unchanged among American Indian/Alaska Native women. Black women, however, have experienced a 38% higher mortality rate than White women, despite having a 5% lower incidence of breast cancer.

In fact, Black women have the lowest survival of any racial and ethnic group for every breast cancer subtype and stage of disease except localized disease.

Additional key findings from the report:

• In 2024, an estimated 310,720 new invasive breast cancers and 56,500 cases of ductal carcinoma in situ will be diagnosed among women in the United States, and an additional 2790 cases will be diagnosed in men.
• On the mortality front, in 2024, approximately 42,250 women are expected to die of breast cancer; 530 breast cancer deaths are anticipated in men.
• As for the lifetime risk for breast cancer, approximately one in eight women in the United States (13.1%) will be diagnosed with invasive breast cancer; 1 in 43 (2.3%) will die from the disease.
• The 5-year relative survival rate for breast cancer is 91%, but that drops to 86% at 10 years and 81% at 15 years.
• The 5-year relative survival rate is over 99% for breast cancer diagnosed at a localized stage but drops to 87% for regional-stage and 32% for distant-stage disease.
• American Indian/Alaska Native women have a 10% lower breast cancer incidence than White women but 6% higher mortality.

Similar to the ACS report, a recent study published in JAMA Network Open reported rising breast cancer incidence among US women aged 20-49 years of different races in different age groups over the past 2 decades.

The increased incidence of breast cancer in younger women “is an area of concern and an area where we really need to spend more effort trying to understand why,” said lead study author and breast surgeon Adetunji T. Toriola, MD, PhD, MPH, of Washington University in St Louis, Missouri.

Although reproductive and lifestyle factors, such as weight gain, diet, and physical activity, may contribute to the growing breast cancer incidence in younger women — and preliminary findings from Dr. Toriola’s own research suggest that reproductive factors may be a particularly strong driver — environmental factors, including exposure to forever chemicals, may also play a role.

Early-life factors, such as exposure to toxins, remain an underexplored area, Dr. Toriola noted, stressing the importance of teasing out the long-term effects of environmental exposures in puberty and during adolescence.

Overall, the trends observed both in this study and the ACS report highlight the need for enhanced prevention efforts that address racial disparities as well as the rising incidence in young women, said Dr. Toriola, also professor of surgery at the Washington University Institute of Public Health, St Louis.

For now, Dr. Toriola urges women to “engage with mammographic screening as soon as qualified” as per guidelines. Women at average risk should go for screening beginning at age 40, and those with a family history or other risk factors should talk to their physician about earlier screening, he said.

Ms. Giaquinto is employed by the ACS, which receives grants from private and corporate foundations, including foundations associated with companies in the health sector, for research outside of the submitted work. Dr. Toriola reported having no disclosures.

Some breast cancer types are more likely than others to recur. Researchers have known this for more than a decade.

But they have long wondered why.

“How did those tumor types arise?” said Christina Curtis, PhD, a professor of medicine, genetics and biomedical data science at Stanford University in California. “They’re all breast cancers. They’re all estrogen receptor positive. But these groups are different. When did they become different, and how is that determined?”

Dr. Curtis and colleagues are finally starting to answer these questions. They recently broke new ground in a study linking differences in cancer-related genes to disease subtype and aggressiveness.

Dr. Curtis and colleagues found that, like fingers molding clay, the genes you’re born with can coax the immune system into shape. DNA inherited from our parents is known as the germline genome. It affects whether the immune system attacks or retreats when confronted with variations that may lead to breast cancer.

“It turns out, the germline genome sculpts tumor evolution,” said Dr. Curtis.

The study is part of a growing effort to understand “precancer” — the critical period after cells have started to grow abnormally but before they’ve developed into cancer — a research trend that could trigger a decisive shift in how cancer treatments are realized. Therapeutics could be designed on the basis of the biology of these precancerous cells.

While biotech start-ups push new tests to catch cancer early, researchers like Dr. Curtis hope to stop cancer before it even starts.

“This is a really exciting area of research,” said Susan Domchek, MD, executive director of the Basser Center for BRCA at the University of Pennsylvania, Philadelphia, who was not involved in the study. “What we hope for is that, over time, we’re going to have more and more biologically driven interception.”
 

‘We’re Basically Unearthing the Dark Matter of the Human Genome’

Of course, we already have mechanical ways of heading off cancer, like having a precancerous polyp removed. But for the Stanford researchers, biologic interception is the goal. They hope to figure out how to use the immune system to stop the cancer.

In their study, they looked at DNA variabilities known as somatic aberrations or single-nucleotide protein sequences (SNPs). The HER2 gene, for example, can contain SNPs — possibly affecting how the HER2 protein regulates breast cell growth and division.

“There’s been a huge effort through genomewide association studies to link SNPs to cancer outcomes and risk,” Dr. Curtis said.

Focusing on people with a genetic predisposition for breast cancer, Dr. Curtis used machine learning to show that these variabilities can occur in specific epitopes (protein features that can trigger an immune response).

They also found that heightened variability can show up in a region of the genome called the human leukocyte antigen (HLA). Each HLA molecule can contain many epitopes.

“We developed a whole new algorithm to compute this ‘germline epitope burden,’ ” Dr. Curtis said. “We’re basically unearthing the dark matter of the human genome to ask about the interplay between SNPs and HLA class one presentation.”

These aberration-rich regions can grab the immune system’s attention. Sometimes the immune system identifies and eradicates those epitopes.

In that case: “I have immunosurveillance. I’ve cured my cancer,” said Nora Disis, PhD, director of the Cancer Vaccine Institute and a professor of medicine at the University of Washington, Seattle. Dr. Disis was not involved in the study.

But other times, the immune system finds a way around the high “epitope burden,” and the tumors become more aggressive and immunosuppressive. That’s when cancer forms.

This suggests a “critical juncture between preinvasive and invasive disease,” Dr. Curtis said.

And that “critical juncture” may very well be the optimal time for intervention.
 

The Precancer Push

Stanford’s findings add information to prior biomarkers and may provide a way to identify “bad-acting tumors” from a simple blood draw measuring germline epitope burden, Dr. Curtis said. Looking further ahead, “this also reveals a new source of epitopes that might be immunogenic and might be informative for the development of vaccines.”

Many labs are trying to understand the biology of precancer and exploring possible vaccines.

The National Cancer Institute’s Human Tumor Atlas Network is building three-dimensional models of the evolution from precancerous to advanced disease. And researchers at the Cancer Vaccine Institute at the University of Washington are developing a vaccine for a precancerous lesion linked to many ovarian cancers.

Dr. Domchek’s research explores whether breast cancers caused by mutations in the BRCA 1 and 2 genes can be intercepted at very early stages. In a clinical trial of healthy people with those mutations, Dr. Domchek and colleagues are attempting to “rev up the immune system to tackle telomerase,” an enzyme that’s over-expressed in 95% of cancers. The hope is for this experimental vaccine to lower their risk of developing cancer.

At the Fred Hutch Cancer Center, Seattle, Ming Yu, PhD, is studying how senescent cells affect immune cells in precancer. As cells age and stop dividing, she said, they can accumulate and create a “tumor-promoting microenvironment” in older people.

Dr. Yu has found that the antiaging drug rapamycin can eliminate those “zombie cells” in mice. She’s studying whether the “cleanup” can help prevent cancer and expects results in a few months.

In the years and decades to come, all of this could lead to a new era in cancer treatment.

“Most drug development starts with people with advanced cancer and then goes into the earlier and earlier spaces,” said Dr. Domchek. “But it may be that we’re thinking about it all wrong and that you really have to understand the unique biology of early lesions to go after them.”

Some breast cancer types are more likely than others to recur. Researchers have known this for more than a decade.

But they have long wondered why.

“How did those tumor types arise?” said Christina Curtis, PhD, a professor of medicine, genetics and biomedical data science at Stanford University in California. “They’re all breast cancers. They’re all estrogen receptor positive. But these groups are different. When did they become different, and how is that determined?”

Dr. Curtis and colleagues are finally starting to answer these questions. They recently broke new ground in a study linking differences in cancer-related genes to disease subtype and aggressiveness.

Dr. Curtis and colleagues found that, like fingers molding clay, the genes you’re born with can coax the immune system into shape. DNA inherited from our parents is known as the germline genome. It affects whether the immune system attacks or retreats when confronted with variations that may lead to breast cancer.

“It turns out, the germline genome sculpts tumor evolution,” said Dr. Curtis.

The study is part of a growing effort to understand “precancer” — the critical period after cells have started to grow abnormally but before they’ve developed into cancer — a research trend that could trigger a decisive shift in how cancer treatments are realized. Therapeutics could be designed on the basis of the biology of these precancerous cells.

While biotech start-ups push new tests to catch cancer early, researchers like Dr. Curtis hope to stop cancer before it even starts.

“This is a really exciting area of research,” said Susan Domchek, MD, executive director of the Basser Center for BRCA at the University of Pennsylvania, Philadelphia, who was not involved in the study. “What we hope for is that, over time, we’re going to have more and more biologically driven interception.”
 

‘We’re Basically Unearthing the Dark Matter of the Human Genome’

Of course, we already have mechanical ways of heading off cancer, like having a precancerous polyp removed. But for the Stanford researchers, biologic interception is the goal. They hope to figure out how to use the immune system to stop the cancer.

In their study, they looked at DNA variabilities known as somatic aberrations or single-nucleotide protein sequences (SNPs). The HER2 gene, for example, can contain SNPs — possibly affecting how the HER2 protein regulates breast cell growth and division.

“There’s been a huge effort through genomewide association studies to link SNPs to cancer outcomes and risk,” Dr. Curtis said.

Focusing on people with a genetic predisposition for breast cancer, Dr. Curtis used machine learning to show that these variabilities can occur in specific epitopes (protein features that can trigger an immune response).

They also found that heightened variability can show up in a region of the genome called the human leukocyte antigen (HLA). Each HLA molecule can contain many epitopes.

“We developed a whole new algorithm to compute this ‘germline epitope burden,’ ” Dr. Curtis said. “We’re basically unearthing the dark matter of the human genome to ask about the interplay between SNPs and HLA class one presentation.”

These aberration-rich regions can grab the immune system’s attention. Sometimes the immune system identifies and eradicates those epitopes.

In that case: “I have immunosurveillance. I’ve cured my cancer,” said Nora Disis, PhD, director of the Cancer Vaccine Institute and a professor of medicine at the University of Washington, Seattle. Dr. Disis was not involved in the study.

But other times, the immune system finds a way around the high “epitope burden,” and the tumors become more aggressive and immunosuppressive. That’s when cancer forms.

This suggests a “critical juncture between preinvasive and invasive disease,” Dr. Curtis said.

And that “critical juncture” may very well be the optimal time for intervention.
 

The Precancer Push

Stanford’s findings add information to prior biomarkers and may provide a way to identify “bad-acting tumors” from a simple blood draw measuring germline epitope burden, Dr. Curtis said. Looking further ahead, “this also reveals a new source of epitopes that might be immunogenic and might be informative for the development of vaccines.”

TOPLINE:

Women with hypothyroidism treated with levothyroxine show no significant cognitive decline across the menopausal transition compared with those without thyroid disease.

METHODOLOGY:

• Levothyroxine, the primary treatment for hypothyroidism, has been linked to perceived cognitive deficits, yet it is unclear whether this is due to the underlying condition being inadequately treated or other factors.
• Using data collected from the Study of Women’s Health Across the Nation, which encompasses five ethnic/racial groups from seven centers across the United States, researchers compared cognitive function over time between women with hypothyroidism treated with levothyroxine and those without thyroid disease.
• Participants underwent cognitive testing across three domains — processing speed, working memory, and episodic memory — which were assessed over a mean follow-up of 13 years.
• Further analyses assessed the impact of abnormal levels of thyroid-stimulating hormone on cognitive outcomes.

TAKEAWAY:

• Of 2033 women included, 227 (mean age, 49.8 years) had levothyroxine-treated hypothyroidism and 1806 (mean age, 50.0 years) did not have thyroid disease; the proportion of women with premenopausal or early perimenopausal status at baseline was higher in the hypothyroidism group (54.2% vs 49.8%; P = .010).
• At baseline, levothyroxine-treated women had higher scores for processing speed (mean score, 56.5 vs 54.4; P = .006) and working memory (mean score, 6.8 vs 6.4; P = .018) than those without thyroid disease; however, no difference in episodic memory was observed between the groups.
• Over the study period, there was no significant difference in cognitive decline between the groups.
• There was no significant effect of levothyroxine-treated hypothyroidism on working memory or episodic memory, although an annual decline in processing speed was observed (P < .001).
• Sensitivity analyses determined that abnormal levels of thyroid-stimulating hormone did not affect cognitive outcomes in women with hypothyroidism.

IN PRACTICE:

When cognitive decline is observed in these patients, the authors advised that “clinicians should resist anchoring on inadequate treatment of hypothyroidism as the cause of these symptoms and may investigate other disease processes (eg, iron deficiency, B12 deficiency, sleep apnea, celiac disease).”

SOURCE:

The study, led by Matthew D. Ettleson, Section of Endocrinology, Diabetes, and Metabolism, University of Chicago, was published online in Thyroid.

LIMITATIONS:

The cognitive assessments in the study were not designed to provide a thorough evaluation of all aspects of cognitive function. The study may not have been adequately powered to detect small effects of levothyroxine-treated hypothyroidism on cognitive outcomes. The higher levels of education attained by the study population may have acted as a protective factor against cognitive decline, potentially biasing the results.

DISCLOSURES:

The Study of Women’s Health Across the Nation was supported by grants from the National Institutes of Health (NIH), DHHS, through the National Institute on Aging, the National Institute of Nursing Research, and the NIH Office of Research on Women’s Health. The authors declared no conflicts of interest.

TOPLINE: 

Women with premature ovarian insufficiency (POI) have a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis and a 2- to 3-fold increased risk for these diseases after diagnosis.
 

METHODOLOGY:

• Researchers conducted a population-based registry study including 3972 women diagnosed with spontaneous POI between 1988 and 2017.
• A total of 15,708 female population controls matched by age and municipality of residence were included for comparison.
• Autoimmune disease diagnoses were evaluated from childhood until the end of 2017 using the Hospital Discharge Registry.
• Women with a history of cancer or bilateral oophorectomy were excluded from the study.

TAKEAWAY:

• Women with POI had a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis compared to controls (odds ratio [OR], 2.6; 95% CI, 2.2-3.1).
• The prevalence of specific autoimmune diseases such as polyglandular autoimmune diseases (OR, 25.8; 95% CI, 9.0-74.1) and Addison disease (OR, 22.9; 95% CI, 7.9-66.1) was significantly higher in women with POI.
• The standardized incidence ratios for being diagnosed with a severe autoimmune disease after POI diagnosis was 2.8 (95% CI, 2.3-3.4) during the first 3 years, decreasing to 1.3 (95% CI, 1.1-1.6) after 12 years.
• No significant difference was found in the prevalence of diabetes type 1 and ankylosing spondylitis between women with POI and the reference cohort.

IN PRACTICE:

“The study results strengthen the hypothesis that autoimmune mechanisms play an important role in the pathogenesis of POI. Future studies should focus on the immunological mechanism of POI from preventative and curative perspectives,” wrote the authors of the study.

SOURCE:

The study was led by Susanna M. Savukoski, Oulu University Hospital in Finland. It was published online in Human Reproduction.

LIMITATIONS: 

The study included only autoimmune disorders diagnosed in specialized health care, which may underestimate the overall prevalence of autoimmune disorders in women with POI. Additionally, the study did not account for confounders such as body mass index and smoking, which are associated with the risk for autoimmune disease and POI.

DISCLOSURES:

Ms. Savukoski received grants from the Finnish Menopause Society, the Finnish Medical Foundation, and the Juho Vainio Foundation. Additional disclosures are noted in the original article.

TOPLINE:

Women with hyperandrogenic polycystic ovary syndrome (PCOS) have lower pregnancy (29.9%) and live birth rates (20.1%) than those with nonhyperandrogenic PCOS (40.2% and 33.1%, respectively).

METHODOLOGY:

• Researchers conducted a retrospective cohort study of 1376 participants from the PPCOS I and II trials, all meeting National Institutes of Health diagnostic criteria for PCOS.
• Participants were categorized into hyperandrogenic (A and B) and nonhyperandrogenic (D) PCOS phenotypes on the basis of medical interviews, demographics, physical examinations, and laboratory data.
• Outcomes of interest included clinical pregnancy, pregnancy loss, live birth, obstetric complications, and neonatal outcomes.
• Fasting blood samples were analyzed for hormonal assays, and Homeostatic Model Assessment for Insulin Resistance scores were calculated using fasting glucose and insulin values.

TAKEAWAY:

• Participants with hyperandrogenic PCOS had higher body mass index (35.5 ± 8.9 vs 31.9 ± 9.3; P < .001) and fasting insulin levels (21.6 ± 27.7 vs 14.7 ± 15.0 μIU/mL; P < .001) than those with nonhyperandrogenic PCOS.
• Participants with hyperandrogenic PCOS had lower odds of achieving pregnancy (odds ratio [OR], 0.63; 95% CI, 0.44-0.92) and live birth (OR, 0.51; 95% CI, 0.34-0.76) than those with nonhyperandrogenic PCOS.
• No significant differences were found in pregnancy loss rates (23.9% vs 32.3%, P = .06) or neonatal outcomes between the two groups.
• The study lacked the power to detect differences in neonatal outcomes because of the low prevalence of these outcomes.

IN PRACTICE:

“Patients with nonhyperandrogenic PCOS may represent a different disease process with unique morbidities and outcomes and could be counseled differently than hyperandrogenic PCOS,” wrote the authors of the study.

SOURCE:

The study was led by Jessica L. Chan, MD, MSCE, Cedars-Sinai Medical Center in Los Angeles, California. It was published online in Obstetrics & Gynecology.

LIMITATIONS:

The primary limitation of this study was that it is a secondary analysis of previously collected randomized controlled trial data, which may affect the availability of certain information. Additionally, the lower number of participants in the nonhyperandrogenic PCOS group could affect the power of the results. The study was underpowered to detect statistically significant differences in neonatal outcomes because of their low prevalence.

DISCLOSURES:

The study was supported by a grant from the ASRM/NICHD/Duke Clinical Research/Reproductive Scientist Training Program. One coauthor disclosed receiving payments from Celmatix, Ferring Pharmaceuticals, Exeltis, Organon, and Monsanto; another disclosed receiving payments from Ferring Pharmaceuticals.

• Participants with hyperandrogenic PCOS had higher body mass index (35.5 ± 8.9 vs 31.9 ± 9.3; P < .001) and fasting insulin levels (21.6 ± 27.7 vs 14.7 ± 15.0 μIU/mL; P < .001) than those with nonhyperandrogenic PCOS.
• Participants with hyperandrogenic PCOS had lower odds of achieving pregnancy (odds ratio [OR], 0.63; 95% CI, 0.44-0.92) and live birth (OR, 0.51; 95% CI, 0.34-0.76) than those with nonhyperandrogenic PCOS.
• No significant differences were found in pregnancy loss rates (23.9% vs 32.3%, P = .06) or neonatal outcomes between the two groups.
• The study lacked the power to detect differences in neonatal outcomes because of the low prevalence of these outcomes.

IN PRACTICE:

“Patients with nonhyperandrogenic PCOS may represent a different disease process with unique morbidities and outcomes and could be counseled differently than hyperandrogenic PCOS,” wrote the authors of the study.

SOURCE:

The study was led by Jessica L. Chan, MD, MSCE, Cedars-Sinai Medical Center in Los Angeles, California. It was published online in Obstetrics & Gynecology.

LIMITATIONS:

The primary limitation of this study was that it is a secondary analysis of previously collected randomized controlled trial data, which may affect the availability of certain information. Additionally, the lower number of participants in the nonhyperandrogenic PCOS group could affect the power of the results. The study was underpowered to detect statistically significant differences in neonatal outcomes because of their low prevalence.

TOPLINE:

Women with hyperandrogenic polycystic ovary syndrome (PCOS) have lower pregnancy (29.9%) and live birth rates (20.1%) than those with nonhyperandrogenic PCOS (40.2% and 33.1%, respectively).

METHODOLOGY:

• Researchers conducted a retrospective cohort study of 1376 participants from the PPCOS I and II trials, all meeting National Institutes of Health diagnostic criteria for PCOS.
• Participants were categorized into hyperandrogenic (A and B) and nonhyperandrogenic (D) PCOS phenotypes on the basis of medical interviews, demographics, physical examinations, and laboratory data.
• Outcomes of interest included clinical pregnancy, pregnancy loss, live birth, obstetric complications, and neonatal outcomes.
• Fasting blood samples were analyzed for hormonal assays, and Homeostatic Model Assessment for Insulin Resistance scores were calculated using fasting glucose and insulin values.

TAKEAWAY:

• Participants with hyperandrogenic PCOS had higher body mass index (35.5 ± 8.9 vs 31.9 ± 9.3; P < .001) and fasting insulin levels (21.6 ± 27.7 vs 14.7 ± 15.0 μIU/mL; P < .001) than those with nonhyperandrogenic PCOS.

MILAN, ITALY — Pregnant women with heightened amygdala activity have a reduced capacity to regulate emotions and report more symptoms of depression than those with lower activity in this brain region, a new imaging study suggested.

If validated, these findings could pave the way for identifying women at higher risk for postpartum depression, said lead researcher Franziska Weinmar, MSc, from the University of Tübingen in Germany.

The study was presented at the 37th European College of Neuropsychopharmacology Congress.
 

Differences in Brain Activity

During pregnancy and the peripartum period, rising hormone levels create a “psychoneuroendocrinological window of vulnerability” for mental health in which 80% of women can develop transitory “baby blues,” and about one in seven develop more serious postpartum depression, Ms. Weinmar told this news organization.

The study included 47 women — 15 pregnant women and 32 nonpregnant controls. The nonpregnant women had normal menstrual cycles; 16 were in the early follicular phase with low estradiol levels (231.7 pmol/L), and 16 had high estradiol levels (516.6 pmol/L) after administration of estradiol.

To examine brain activity, participants were asked to view negative emotional images while undergoing functional MRI. They were then asked to use cognitive reappraisal to regulate their emotional response to the images.

The findings showed that both pregnant and nonpregnant women were equally successful at emotional regulation, but this process involved different brain activity in pregnant vs their nonpregnant counterpart.

All women had increased left middle frontal gyrus activity when regulating their emotions, but there was a difference in the amygdala between the pregnancy group and controls, Ms. Weinmar noted.

This suggests that pregnant women may have to exert more neural effort in emotional regulation, she said. “And pregnant women with higher amygdala activity were less able to regulate their emotions successfully compared to those with less amygdala activity.”

Linear regression analyses were performed to assess the relation of brain activity during down-regulation, regulation success, and self-reported depression scores, and this showed that higher amygdala activity was also associated with higher depression scores.

“We need to be cautious in interpreting this,” said Ms. Weinmar. “This is a small sample, and we are the first to undertake this work.”

Nonetheless, she said that if the findings are confirmed by larger studies, pregnant women could be assessed “in the waiting room” using existing questionnaires that evaluate emotional regulation.

If a woman has difficulties with emotion regulation, “there are adaptive strategies, like cognitive reappraisal that a counseling psychotherapist can help with,” said Ms. Weinmar.

“I could also imagine group sessions, for example, or online courses,” she said, adding that obstetricians could also be trained to identify these women.

Commenting on the findings in a press release, Susana Carmona, PhD, from Gregorio Marañón Hospital in Madrid, Spain, said research like this is crucial for gaining insight into one of the most intense physiological processes a human can undergo: pregnancy. It’s remarkable how much remains unknown.

“Recently, the FDA [Food and Drug Administration] approved the first treatment for postpartum depression. However, we still have a long way to go in characterizing what happens in the brain during pregnancy, identifying biomarkers that can indicate the risk of developing perinatal mental disorders, and designing strategies to prevent mother and infant suffering during the delicate and critical peripartum period,” Dr. Carmona added.

The study was supported by the Center for Integrative Neuroscience in Tübingen, Germany, and the International Research Training Group “Women’s Mental Health Across the Reproductive Years” (IRTG 2804). Ms. Weinmar and Dr. Carmona reported no relevant disclosures.

TOPLINE:

Diabetes is associated with a lower incidence of uterine fibroids in midlife women receiving diabetes treatment, especially metformin. The association between diabetes and the risk for uterine fibroids may vary based on menopausal status.

METHODOLOGY:

• Previous studies have provided inconsistent evidence regarding associations between the risk for uterine fibroids and markers of cardiometabolic health, such as fasting insulin, fasting glucose, and diabetes.
• Researchers conducted a prospective cohort study to examine the association of fasting levels of cardiometabolic blood biomarkers, diabetes, and diabetes treatment with the incidence of new fibroid diagnoses in midlife women.
• They included participants from the Study of Women’s Health Across the Nation cohort who reported fibroid diagnoses at enrollment and during 13 follow-up visits.
• At all visits, levels of glucose, insulin, and sex hormone–binding globulin (SHBG) were measured in fasting blood samples, and homeostatic model assessment for insulin resistance (HOMA-IR) was calculated.
• Discrete-time survival models were used to estimate the hazard ratios (HRs) for the associations of biomarkers and diabetes with fibroid diagnoses, adjusted for demographics and healthcare utilization.

TAKEAWAY:

• Researchers identified 2570 eligible women (median age, 45 years; 45% perimenopausal women), among whom approximately 3% had diabetes at baseline.
• Diabetes was associated with a 28% lower incidence of new fibroid diagnosis (adjusted HR, 0.72).
• This association was particularly strong among participants with treated diabetes, especially those on metformin, who had a 51% lower incidence of self-reported fibroids than those without diabetes. The estimates, however, had wide CIs suggesting uncertainty.
• Time-varying HOMA-IR and SHBG, insulin, and glucose levels were not significantly associated with the new fibroid diagnosis.
• When stratified by menopausal status, higher HOMA-IR and insulin levels were associated with a greater incidence of fibroid diagnosis during premenopause but not during perimenopause.

IN PRACTICE:

“Our findings contribute to preliminary evidence indicating a protective association between diabetes and risk of incident fibroids,” the authors wrote.

SOURCE:

The study was led by Susanna D. Mitro, Division of Research, Kaiser Permanente, Pleasanton, California, and was published online in The Journal of Clinical Endocrinology & Metabolism.

LIMITATIONS:

The study relied on self-reported fibroid diagnoses, which may result in the misclassification of cases. The sample size of participants with diabetes was small, which resulted in reduced precision and confidence in the findings. The baseline eligibility criteria (midlife participants with an intact uterus and no history of fibroid incidence) may have limited the generalizability of the findings to the wider population at risk for fibroids.

DISCLOSURES:

This study was supported by the National Institutes of Health (NIH), through the National Institute on Aging, the National Institute of Nursing Research, and the NIH Office of Research on Women’s Health. One author reported being a consultant and adviser for various pharmaceutical companies. Two other authors reported receiving salary support and royalties from various pharmaceutical companies and organizations.

Gestational carriers face a significantly higher risk for severe maternal morbidity and other pregnancy complications than those conceiving naturally or via in vitro fertilization (IVF), according to a recent Canadian study.

These findings suggest that more work is needed to ensure careful selection of gestational carriers, reported lead author Maria P. Velez, MD, PhD, of McGill University, Montreal, Quebec, Canada, and colleagues.

“Although a gestational carrier should ideally be a healthy person, with a demonstrated low-risk obstetric history, it is not clear whether this occurs in practice,” the investigators wrote in Annals of Internal Medicine. “Moreover, the risk for maternal and neonatal adversity is largely unknown in this group.”
 

Study Compared Gestational Carriage With IVF and Unassisted Conception

To address these knowledge gaps, Dr. Velez and colleagues conducted a population-based cohort study in Ontario using linked administrative datasets. All singleton births at more than 20 weeks’ gestation with mothers aged 18-50 years were included from April 2012 to March 2021. Multifetal pregnancies were excluded, as were women with a history of infertility diagnosis without fertility treatment, and those who underwent intrauterine insemination or ovulation induction.

Outcomes were compared across three groups: Unassisted conception, IVF, and gestational carriage. The primary maternal outcome was severe maternal morbidity, defined by a validated composite of 41 unique indicators. The primary infant outcome was severe neonatal morbidity, comprising 19 unique indicators.

Secondary outcomes were hypertensive disorders, elective cesarean delivery, emergent cesarean delivery, preterm birth at less than 37 weeks, preterm birth at more than 32 weeks, and postpartum hemorrhage.

Logistic regression analysis adjusted for a range of covariates, including age, obesity, tobacco/drug dependence, chronic hypertension, and others. The final dataset included 846,124 births by unassisted conception (97.6%), 16,087 by IVF (1.8%), and 806 by gestational carriage (0.1%).

The weighted relative risk (wRR) for severe maternal morbidity was more than three times higher in gestational carriers than in those conceiving naturally (wRR, 3.30; 95% CI, 2.59-4.20) and 86% higher than in those conceiving via IVF (wRR, 1.86; 95% CI, 1.36-2.55). These stem from absolute risks of 2.3%, 4.3%, and 7.8% for unassisted, IVF, and surrogate pregnancies, respectively.

Moreover, surrogates were 75% more likely to have hypertensive disorders, 79% more likely to have preterm birth at less than 37 weeks, and almost three times as likely to have postpartum hemorrhage.

These same three secondary outcomes were also significantly more common when comparing surrogate with IVF pregnancies, albeit to a lesser degree. In contrast, surrogate pregnancies were associated with a 21% lower risk for elective cesarean delivery than IVF pregnancies (wRR, 0.79; 95% CI, 0.68-0.93).

Severe neonatal morbidity was not significantly different between the groups. These findings add to a mixed body of evidence surrounding both maternal and neonatal outcomes with gestational carriers, according to the investigators.

“Prior small studies [by Söderström-Anttila et al. and Swanson et al.] reported varying risks for preterm birth in singleton gestational carriage pregnancies, whereas a recent large US registry reported no increased risk for preterm birth compared with IVF, after accounting for multifetal pregnancy,” they wrote. “This study excluded multifetal pregnancies, a common occurrence after IVF, with reported higher risks for adverse outcomes. Accordingly, adverse maternal and newborn outcomes may have been underestimated herein.”
 

Causes of Worse Outcomes Remain Unclear

While the present findings suggest greater maternal morbidity among surrogates, potential causes of these adverse outcomes remain unclear.

The investigators suggested that implantation of a nonautologous embryo could be playing a role, as oocyte donation has been linked with an increased risk for hypertensive disorders of pregnancy.

“We don’t know exactly why that can happen,” Dr. Velez said in an interview. “Maybe that embryo can be associated with an immunological response that could be associated with higher morbidity during pregnancy. We need, however, other studies that can continue testing that hypothesis.”

In the meantime, more care is needed in surrogate selection, according to Dr. Velez.

“In our study, we found that there were patients, for example, who had more than three prior C-sections, which is one of the contraindications for gestational carriers, and patients who had more than five [prior] pregnancies, which is also another limitation in the guidelines for choosing these patients,” she said. “Definitely we need to be more vigilant when we accept these gestational carriers.”

But improving surrogate selection may be easier said than done.

The quantitative thresholds cited by Dr. Velez come from the American Society for Reproductive Medicine guidelines. Alternative guidance documents from the Canadian Fertility and Andrology Society and American College of Obstetricians and Gynecologists are less prescriptive; instead, they offer qualitative recommendations concerning obstetric history and risk assessment.

And then there is the regulatory specter looming over the entire field, evidenced by the many times that these publications cite ethical and legal considerations — far more than the average medical guidance document — when making clinical decisions related to surrogacy.
 

Present Study Offers Much-Needed Data in Understudied Field

According to Kate Swanson, MD, a perinatologist, clinical geneticist, and associate professor at the University of California San Francisco, the present study may help steer medical societies and healthcare providers away from these potential sand traps and toward conversations grounded in scientific data.

“I think one of the reasons that the Society for Maternal-Fetal Medicine and the maternal-fetal medicine community in general hasn’t been interested in this subject is that they see it as a social/ethical/legal issue rather than a medical one,” Dr. Swanson said in an interview. “One of the real benefits of this article is that it shows that this is a medical issue that the obstetric community needs to pay attention to.”

These new data could help guide decisions about risk and candidacy with both potential gestational carriers and intended parents, she said.

Still, it’s hard — if not impossible — to disentangle the medical and legal aspects of surrogacy, as shown when analyzing the present study.

In Canada, where it was conducted, intended parents are forbidden from paying surrogates for their services beyond out-of-pocket costs directly related to pregnancy. Meanwhile, surrogacy laws vary widely across the United States; some states (eg, Louisiana) allow only altruistic surrogacy like Canada, while other states (eg, California) permit commercial surrogacy with no legal limits on compensation.

Dr. Swanson and Dr. Velez offered starkly different views on this topic.

“I think there should be more regulations in terms of compensating [gestational carriers],” Dr. Velez said. “I don’t think being a gestational carrier should be like a job or a way of making a living.”

Dr. Swanson, who has published multiple studies on gestational carriage and experienced the process as an intended parent, said compensation beyond expenses is essential.

“I do think it’s incredibly reasonable to pay someone — a woman is taking on quite a lot of inconvenience and risk — in order to perform this service for another family,” she said. “I think it’s incredibly appropriate to compensate her for all of that.”

Reasons for compensation go beyond the ethical, Dr. Swanson added, and may explain some of the findings from the present study.

“A lot of these gestational carriers [in the present dataset] wouldn’t necessarily meet criteria through the American Society of Reproductive Medicine,” Dr. Swanson said, pointing out surrogates who had never had a pregnancy before or reported the use of tobacco or other drugs. “Really, it shows me that a lot of the people participating as gestational carriers were maybe not ideal candidates. I think one of the reasons that we might see that in this Canadian population is ... that you can’t compensate someone, so I think their pool of people willing to be gestational carriers is a lot smaller, and they may be a little bit less selective sometimes.”

Dr. Velez acknowledged that the present study was limited by a shortage of potentially relevant information concerning the surrogacy selection process, including underlying reasons for becoming a gestational carrier. More work is needed to understand the health and outcomes of these women, she said, including topics ranging from immunologic mechanisms to mental health.

She also called for more discussions surrounding maternal safety, with participation from all stakeholders, including governments, surrogates, intended parents, and physicians too.

This study was funded by the Canadian Institutes of Health Research. The investigators disclosed no conflicts of interest. Dr. Swanson disclosed a relationship with Mitera.

To address these knowledge gaps, Dr. Velez and colleagues conducted a population-based cohort study in Ontario using linked administrative datasets. All singleton births at more than 20 weeks’ gestation with mothers aged 18-50 years were included from April 2012 to March 2021. Multifetal pregnancies were excluded, as were women with a history of infertility diagnosis without fertility treatment, and those who underwent intrauterine insemination or ovulation induction.

Outcomes were compared across three groups: Unassisted conception, IVF, and gestational carriage. The primary maternal outcome was severe maternal morbidity, defined by a validated composite of 41 unique indicators. The primary infant outcome was severe neonatal morbidity, comprising 19 unique indicators.

Secondary outcomes were hypertensive disorders, elective cesarean delivery, emergent cesarean delivery, preterm birth at less than 37 weeks, preterm birth at more than 32 weeks, and postpartum hemorrhage.

Logistic regression analysis adjusted for a range of covariates, including age, obesity, tobacco/drug dependence, chronic hypertension, and others. The final dataset included 846,124 births by unassisted conception (97.6%), 16,087 by IVF (1.8%), and 806 by gestational carriage (0.1%).

The weighted relative risk (wRR) for severe maternal morbidity was more than three times higher in gestational carriers than in those conceiving naturally (wRR, 3.30; 95% CI, 2.59-4.20) and 86% higher than in those conceiving via IVF (wRR, 1.86; 95% CI, 1.36-2.55). These stem from absolute risks of 2.3%, 4.3%, and 7.8% for unassisted, IVF, and surrogate pregnancies, respectively.

Moreover, surrogates were 75% more likely to have hypertensive disorders, 79% more likely to have preterm birth at less than 37 weeks, and almost three times as likely to have postpartum hemorrhage.

These same three secondary outcomes were also significantly more common when comparing surrogate with IVF pregnancies, albeit to a lesser degree. In contrast, surrogate pregnancies were associated with a 21% lower risk for elective cesarean delivery than IVF pregnancies (wRR, 0.79; 95% CI, 0.68-0.93).

Severe neonatal morbidity was not significantly different between the groups. These findings add to a mixed body of evidence surrounding both maternal and neonatal outcomes with gestational carriers, according to the investigators.

“Prior small studies [by Söderström-Anttila et al. and Swanson et al.] reported varying risks for preterm birth in singleton gestational carriage pregnancies, whereas a recent large US registry reported no increased risk for preterm birth compared with IVF, after accounting for multifetal pregnancy,” they wrote. “This study excluded multifetal pregnancies, a common occurrence after IVF, with reported higher risks for adverse outcomes. Accordingly, adverse maternal and newborn outcomes may have been underestimated herein.”
 

Causes of Worse Outcomes Remain Unclear

While the present findings suggest greater maternal morbidity among surrogates, potential causes of these adverse outcomes remain unclear.

The investigators suggested that implantation of a nonautologous embryo could be playing a role, as oocyte donation has been linked with an increased risk for hypertensive disorders of pregnancy.

“We don’t know exactly why that can happen,” Dr. Velez said in an interview. “Maybe that embryo can be associated with an immunological response that could be associated with higher morbidity during pregnancy. We need, however, other studies that can continue testing that hypothesis.”

In the meantime, more care is needed in surrogate selection, according to Dr. Velez.

“In our study, we found that there were patients, for example, who had more than three prior C-sections, which is one of the contraindications for gestational carriers, and patients who had more than five [prior] pregnancies, which is also another limitation in the guidelines for choosing these patients,” she said. “Definitely we need to be more vigilant when we accept these gestational carriers.”

But improving surrogate selection may be easier said than done.

The quantitative thresholds cited by Dr. Velez come from the American Society for Reproductive Medicine guidelines. Alternative guidance documents from the Canadian Fertility and Andrology Society and American College of Obstetricians and Gynecologists are less prescriptive; instead, they offer qualitative recommendations concerning obstetric history and risk assessment.

And then there is the regulatory specter looming over the entire field, evidenced by the many times that these publications cite ethical and legal considerations — far more than the average medical guidance document — when making clinical decisions related to surrogacy.
 

Present Study Offers Much-Needed Data in Understudied Field

According to Kate Swanson, MD, a perinatologist, clinical geneticist, and associate professor at the University of California San Francisco, the present study may help steer medical societies and healthcare providers away from these potential sand traps and toward conversations grounded in scientific data.

“I think one of the reasons that the Society for Maternal-Fetal Medicine and the maternal-fetal medicine community in general hasn’t been interested in this subject is that they see it as a social/ethical/legal issue rather than a medical one,” Dr. Swanson said in an interview. “One of the real benefits of this article is that it shows that this is a medical issue that the obstetric community needs to pay attention to.”

These new data could help guide decisions about risk and candidacy with both potential gestational carriers and intended parents, she said.

Still, it’s hard — if not impossible — to disentangle the medical and legal aspects of surrogacy, as shown when analyzing the present study.

In Canada, where it was conducted, intended parents are forbidden from paying surrogates for their services beyond out-of-pocket costs directly related to pregnancy. Meanwhile, surrogacy laws vary widely across the United States; some states (eg, Louisiana) allow only altruistic surrogacy like Canada, while other states (eg, California) permit commercial surrogacy with no legal limits on compensation.

Dr. Swanson and Dr. Velez offered starkly different views on this topic.

“I think there should be more regulations in terms of compensating [gestational carriers],” Dr. Velez said. “I don’t think being a gestational carrier should be like a job or a way of making a living.”

Dr. Swanson, who has published multiple studies on gestational carriage and experienced the process as an intended parent, said compensation beyond expenses is essential.

“I do think it’s incredibly reasonable to pay someone — a woman is taking on quite a lot of inconvenience and risk — in order to perform this service for another family,” she said. “I think it’s incredibly appropriate to compensate her for all of that.”

Reasons for compensation go beyond the ethical, Dr. Swanson added, and may explain some of the findings from the present study.

“A lot of these gestational carriers [in the present dataset] wouldn’t necessarily meet criteria through the American Society of Reproductive Medicine,” Dr. Swanson said, pointing out surrogates who had never had a pregnancy before or reported the use of tobacco or other drugs. “Really, it shows me that a lot of the people participating as gestational carriers were maybe not ideal candidates. I think one of the reasons that we might see that in this Canadian population is ... that you can’t compensate someone, so I think their pool of people willing to be gestational carriers is a lot smaller, and they may be a little bit less selective sometimes.”

Dr. Velez acknowledged that the present study was limited by a shortage of potentially relevant information concerning the surrogacy selection process, including underlying reasons for becoming a gestational carrier. More work is needed to understand the health and outcomes of these women, she said, including topics ranging from immunologic mechanisms to mental health.

She also called for more discussions surrounding maternal safety, with participation from all stakeholders, including governments, surrogates, intended parents, and physicians too.

This study was funded by the Canadian Institutes of Health Research. The investigators disclosed no conflicts of interest. Dr. Swanson disclosed a relationship with Mitera.

Gestational carriers face a significantly higher risk for severe maternal morbidity and other pregnancy complications than those conceiving naturally or via in vitro fertilization (IVF), according to a recent Canadian study.

These findings suggest that more work is needed to ensure careful selection of gestational carriers, reported lead author Maria P. Velez, MD, PhD, of McGill University, Montreal, Quebec, Canada, and colleagues.

“Although a gestational carrier should ideally be a healthy person, with a demonstrated low-risk obstetric history, it is not clear whether this occurs in practice,” the investigators wrote in Annals of Internal Medicine. “Moreover, the risk for maternal and neonatal adversity is largely unknown in this group.”

TOPLINE:

Electronic health record (EHR)–derived family history identified 29,913 patients with familial risk for hereditary breast and ovarian cancer, but 82% had no evidence of genetic testing. Seven-question family history screening (FHS7)–positive status was associated with a threefold increase in BRCA1/2 positivity and a 44% increase in cancer risk among women.

METHODOLOGY:

• A cross-sectional and retrospective cohort analysis used EHR data from Renown Health in northern Nevada. The study period spanned from January 1, 2018, to February 1, 2024, with data on demographic variables, healthcare utilization, and cancer diagnoses.
• The study aimed to use the FHS7 to identify patients meeting family history criteria for genetic testing (familial risk for hereditary breast and ovarian cancer) in their EHRs; patients meeting the FHS7 criteria were deemed to be FHS7-positive.
• A total of 835,727 patients aged 18-79 years were included, with genotype data available for 38,003 participants from the Healthy Nevada Project, which notified 330 individuals with BRCA1/2 variants of their genetic risk.
• The primary outcomes were the presence of pathogenic or likely pathogenic variants in specific genes and the diagnosis of cancer.

TAKEAWAY:

• FHS7-positive status was associated with a 3.34-fold increase in BRCA1/2 positivity among female participants and a 3.35-fold increase among male participants (95% CI, 2.48-4.47 and 1.93-5.56, respectively).
• Female FHS7-positive participants had a 1.62-fold increase in CHEK2 positivity and a 2.84-fold increase in PALB2 positivity (95% CI, 1.05-2.43 and 1.23-6.16, respectively).
• Age-adjusted cancer incidence rates were higher for FHS7-positive patients, with 367.2 cases per 100,000 per year for women and 309.9 cases per 100,000 per year for men.
• The number needed to test to detect one BRCA1/2-positive patient decreased from 128 to 53 for women and from 119 to 42 for men when prescreening with FHS7.

IN PRACTICE:

“EHR-derived FHS7 identified thousands of patients with familial risk for breast cancer, indicating a substantial gap in genetic testing,” the study authors wrote. “Survey results suggest that most patients who are FHS7-positive in their EHR truly meet family history criteria, but that EHR-derived FHS7 may miss many patients who would be FHS7-positive if approached with a direct questionnaire,” the author wrote.

SOURCE:

The study was led by Daniel Kiser, MS, University of Nevada, Reno School of Medicine. It was published online in JAMA Network Open.

LIMITATIONS: 

The study’s observational design may introduce self-selection biases, particularly among Healthy Nevada Project participants. The 21.8% response rate to the survey suggests potential self-selection among respondents. The tendency of less healthy patients to have more data available in their EHRs could influence the authors’ analysis of cancer incidence rates, despite adjustments for healthcare utilization levels.
