VANCOUVER – With treatment with a bisphosphonate following sequential use of teriparatide (Forteo) and denosumab (Prolia) for premenopausal women with idiopathic osteoporosis, bone mineral density (BMD) was maintained over the first year following denosumab cessation, according to results from a small, nonrandomized extension of a phase 2 study.

Bisphosphonates are recommended for patients after they have completed a course of denosumab because cessation of the bone resorption blocker is known to increase bone turnover markers, decrease BMD, and raise the risk of vertebral fractures. Although there is evidence to support this treatment sequence for postmenopausal women, there was no evidence regarding premenopausal women with idiopathic osteoporosis, said Adi Cohen, MD, who presented the results of the study at the annual meeting of the American Society for Bone and Mineral Research.

In the extension study, neither length of treatment with denosumab nor transition to menopause affected BMD results. Weekly doses of alendronate (ALN) better suppressed C-terminal telopeptide (CTX) than did zoledronic acid (ZOL) and led to better maintenance of BMD than did a single dose of ZOL. The researchers suggested that single-dose ZOL may not prevent bone loss for an entire year.

It is too early to call the results practice changing, said Dr. Cohen, professor of medicine and endocrinology at Columbia University Irving Medical Center, New York, but she noted, “It’s important just to provide information about how sequences of osteoporosis medications might be used in a rare but certainly understudied group of premenopausal women with osteoporosis who need treatment, and these data hopefully will help make some treatment decisions.”

In the early 2000s, researchers initially believed that premenopausal women with low BMD had experienced some kind of temporary event and that they would likely improve on their own over time. “I think we now recognize that whatever it is that causes this is an ongoing issue and that this is a problem they’re going to have to deal with for the rest of their lives. This is something that they have to stay on top of,” said coauthor Elizabeth Shane, MD, who is a professor of medicine at CUIMC.

However, there are no practice guidelines for the management of osteoporosis in premenopausal women, according to Dr. Shane. She noted that there is controversy as to whether to treat women with low bone density who do not have a history of fractures. “I think that there’s pretty much agreement that anybody who has a lot of fractures has an early-onset form of osteoporosis. The controversy is what to do about the person who just has a low bone density and hasn’t yet fractured and what is the utility of trying to treat them at that point and perhaps prevent a fracture. I don’t think we have enough data to address that,” Dr. Shane said.

Still, the research has provided some clarity in her own practice. “I think if somebody would come to my office who had very low bone density, I would probably treat them. If they have fractures, I would definitely treat them. I think that our work has provided a framework for people to approach that,” she said.

The study was an extension of a sequential treatment approach that began with 2 years of teriparatide (20 mcg daily) followed by an extension study of 2–3 years of treatment with denosumab (60 mg every 6 months). Seven months after the last dose of denosumab, patients underwent 1 year of treatment with ALN (70 mg weekly; n = 18) or a single dose of ZOL (5 mg IV; n = 6), according to patient choice.

The original phase 2 study started with 41 women. At 24 months, teriparatide treatment led to BMD increases of 13% in the lumbar spine (LS), 5% in the total hip (TH), and 5% in the femoral neck (FN). There was a 2% decline in BMD in the forearm (distal radius [DR]). A group of 32 of the women participated in an extension study and took denosumab for 12 months. Of those patients, 29 continued to take it for another 12 months. At 12 months, BMD increased 5% in the LS, 3% in the TH, 3% in the FN, and 1% in the DR (P < .05 for all). At 24 months, BMD rose by 22%, 10%, and 10% at the first three of those locations. BMD in the DR remained stable, compared with the baseline after taking teriparatide.

The bisphosphonate phase of the extension study included 24 women (mean age, 43 years). The mean body mass index of the patients was 23.0 kg/m². The patients had experienced a mean of 3.0 fractures in adulthood, and 38% of patients had a history of vertebral fracture.

Over 12 months of follow-up, the researchers found no statistically significant difference in BMD in the LS, TH, or FN, compared with bisphosphonate extension baseline. There was also no statistically significant change in serum CTX. There was evidence that, among patients with higher rates of bone turnover, there were higher rates of LS and FN bone loss during bisphosphonate treatment.

Among patients taking ZOL, at 12 months there was a statistically significant rise in CTX levels, but not among patients taking ALN. There were no new vertebral fractures among any participants during the bisphosphonate extension period.

The results represent critical data for an understudied population, according to Yumie Rhee, MD, PhD, who was comoderator of the session in which the study was presented. “They are showing that by using a bisphosphonate [patients] have this just slight decrease, but within error, so it’s maintaining the BMD, at least. I think it’s very important. It will be fascinating to see next year’s follow-up,” said Dr. Rhee, a professor of endocrinology at Yonsei University College of Medicine in Seoul, South Korea. “The problem with premenopausal osteoporosis is that we don’t have good evidence. Even though this study is very small, we’re just following that data, all of us.”

Comoderator Maria Zanchetta, MD, a professor of osteology at the Institute of Diagnostics and Metabolic Research, Universidad del Salvador, Buenos Aires, agreed. “We know what to do when we stop denosumab in postmenopausal women. We didn’t have any work about what to do when we stopped in premenopausal women. You can think that probably it’s going to be the same, but this is the first time you have the evidence that if you give bisphosphonate, you will maintain BMD.”

Limitations to the study include its small size and the lack of a placebo-treated control group. In addition, the bisphosphonate extension was not randomized.

The studies were funded by the U.S. Food and Drug Administration and Amgen. Dr. Cohen and Dr. Shane received research funding from Amgen. Dr. Rhee and Dr. Zanchetta have disclosed no relevant financial relationships.

In 2021, diabetes and related complications was the 8th leading cause of death in the United States.¹ As of 2022, more than 11% of the U.S. population had diabetes and 38% of the adult U.S. population had prediabetes.² Diabetes is the most expensive chronic condition in the United States, where $1 of every $4 in health care costs is spent on care.³

Where this is most concerning is diabetes in pregnancy. While childbirth rates in the United States have decreased since the 2007 high of 4.32 million births⁴ to 3.66 million in 2021,⁵ the incidence of diabetes in pregnancy – both pregestational and gestational – has increased. The rate of pregestational diabetes in 2021 was 10.9 per 1,000 births, a 27% increase from 2016 (8.6 per 1,000).⁶ The percentage of those giving birth who also were diagnosed with gestational diabetes mellitus (GDM) was 8.3% in 2021, up from 6.0% in 2016.⁷

Diabetes in pregnancy not only increases risks of adverse events for mother and fetus: Increasing research suggests the condition signals longer-term risks for the mother and child throughout their lifetimes. Adverse outcomes for an infant born to a mother with diabetes include a higher risk of obesity and diabetes as adults, potentially leading to a forward-feeding cycle.

We and our colleagues established the Diabetes in Pregnancy Study Group of North America in 1997 because we had witnessed too frequently the devastating diabetes-induced pregnancy complications in our patients. The mission we set forth was to provide a forum for dialogue among maternal-fetal medicine subspecialists. The three main goals we set forth to support this mission were to provide a catalyst for research, contribute to the creation and refinement of medical policies, and influence professional practices in diabetes in pregnancy.⁸

In the last quarter century, DPSG-NA, through its annual and biennial meetings, has brought together several hundred practitioners that include physicians, nurses, statisticians, researchers, nutritionists, and allied health professionals, among others. As a group, it has improved the detection and management of diabetes in pregnant women and their offspring through knowledge sharing and influencing policies on GDM screening, diagnosis, management, and treatment. Our members have shown that preconceptional counseling for women with diabetes can significantly reduce congenital malformation and perinatal mortality compared with those women with pregestational diabetes who receive no counseling.^9,10

We have addressed a wide variety of topics including the paucity of data in determining the timing of delivery for women with diabetes and the Institute of Medicine/National Academy of Medicine recommendations of gestational weight gain and risks of not adhering to them. We have learned about new scientific discoveries that reveal underlying mechanisms to diabetes-related birth defects and potential therapeutic targets; and we have discussed the health literacy requirements, ethics, and opportunities for lifestyle intervention.^11-16

But we need to do more.

Two risk factors are at play: Women continue to choose to have babies at later ages and their pregnancies continue to be complicated by the rising incidence of obesity (see Figure 1 and Figure 2).

Dr. Reece and Dr. Miodovnik

The global obesity epidemic has become a significant concern for all aspects of health and particularly for diabetes in pregnancy.

Dr. Reece and Dr. Miodovnik

In 1990, 24.9% of women in the United States were obese; in 2010, 35.8%; and now more than 41%. Some experts project that by 2030 more than 80% of women in the United States will be overweight or obese.²¹

If we are to stop this cycle of diabetes begets more diabetes, now more than ever we need to come together and accelerate the research and education around the diabetes in pregnancy. Join us at this year’s DPSG-NA meeting Oct. 26-28 to take part in the knowledge sharing, discussions, and planning. More information can be found online at https://events.dpsg-na.com/home.

In 2021, diabetes and related complications was the 8th leading cause of death in the United States.¹ As of 2022, more than 11% of the U.S. population had diabetes and 38% of the adult U.S. population had prediabetes.² Diabetes is the most expensive chronic condition in the United States, where $1 of every $4 in health care costs is spent on care.³

Where this is most concerning is diabetes in pregnancy. While childbirth rates in the United States have decreased since the 2007 high of 4.32 million births⁴ to 3.66 million in 2021,⁵ the incidence of diabetes in pregnancy – both pregestational and gestational – has increased. The rate of pregestational diabetes in 2021 was 10.9 per 1,000 births, a 27% increase from 2016 (8.6 per 1,000).⁶ The percentage of those giving birth who also were diagnosed with gestational diabetes mellitus (GDM) was 8.3% in 2021, up from 6.0% in 2016.⁷

Diabetes in pregnancy not only increases risks of adverse events for mother and fetus: Increasing research suggests the condition signals longer-term risks for the mother and child throughout their lifetimes. Adverse outcomes for an infant born to a mother with diabetes include a higher risk of obesity and diabetes as adults, potentially leading to a forward-feeding cycle.

We and our colleagues established the Diabetes in Pregnancy Study Group of North America in 1997 because we had witnessed too frequently the devastating diabetes-induced pregnancy complications in our patients. The mission we set forth was to provide a forum for dialogue among maternal-fetal medicine subspecialists. The three main goals we set forth to support this mission were to provide a catalyst for research, contribute to the creation and refinement of medical policies, and influence professional practices in diabetes in pregnancy.⁸

In the last quarter century, DPSG-NA, through its annual and biennial meetings, has brought together several hundred practitioners that include physicians, nurses, statisticians, researchers, nutritionists, and allied health professionals, among others. As a group, it has improved the detection and management of diabetes in pregnant women and their offspring through knowledge sharing and influencing policies on GDM screening, diagnosis, management, and treatment. Our members have shown that preconceptional counseling for women with diabetes can significantly reduce congenital malformation and perinatal mortality compared with those women with pregestational diabetes who receive no counseling.^9,10

We have addressed a wide variety of topics including the paucity of data in determining the timing of delivery for women with diabetes and the Institute of Medicine/National Academy of Medicine recommendations of gestational weight gain and risks of not adhering to them. We have learned about new scientific discoveries that reveal underlying mechanisms to diabetes-related birth defects and potential therapeutic targets; and we have discussed the health literacy requirements, ethics, and opportunities for lifestyle intervention.^11-16

But we need to do more.

Two risk factors are at play: Women continue to choose to have babies at later ages and their pregnancies continue to be complicated by the rising incidence of obesity (see Figure 1 and Figure 2).

Dr. Reece and Dr. Miodovnik

The global obesity epidemic has become a significant concern for all aspects of health and particularly for diabetes in pregnancy.

Dr. Reece and Dr. Miodovnik

In 1990, 24.9% of women in the United States were obese; in 2010, 35.8%; and now more than 41%. Some experts project that by 2030 more than 80% of women in the United States will be overweight or obese.²¹

If we are to stop this cycle of diabetes begets more diabetes, now more than ever we need to come together and accelerate the research and education around the diabetes in pregnancy. Join us at this year’s DPSG-NA meeting Oct. 26-28 to take part in the knowledge sharing, discussions, and planning. More information can be found online at https://events.dpsg-na.com/home.

For women who are obese, daily life is wrought with landmines. Whether it’s the challenges of air travel because plane seats are too small, the need to shield themselves from the world’s discriminating eyes, or the great lengths many will go to achieve better health and the promise of longevity, navigating life as an obese person requires a thick skin.

So, it’s no wonder so many are willing to pay more than $1,000 a month out of pocket to get their hands on drugs like semaglutide (Ozempic and Wegovy) or tirzepatide (Mounjaro). The benefits of these drugs, which are part of a new class called glucagonlike peptide–1 (GLP-1) receptor agonists, include significant and rapid weight loss, blood sugar control, and improved life quality; they are unprecedented in a setting where surgery has long been considered the most effective long-term option.

On the flip side, the desire for rapid weight loss and better blood sugar control also comes with an unexpected cost. Many women living with obesity who take oral contraceptives are unaware that these drugs – especially Mounjaro – can interfere with the absorption of birth control pills and how well they work, making an unintended pregnancy more likely.

Neel Shah, MD, an endocrinologist and associate professor at the University of Texas Health Science Center at Houston, said he has had several patients become pregnant without intending to. 

“It was when Mounjaro came out on the market when we started using it,” he said of the drug the Food and Drug Administration approved for type 2 diabetes in 2022. “It [the warning] was in the product insert, but clinically speaking, I don’t know if it was at the top of providers’ minds when they were prescribing Mounjaro.”

When asked if he believed that we were going to be seeing a significant increase in so-called Mounjaro babies, Dr. Shah was sure in his response. 

“Absolutely. We will because the sheer volume [of patients] will increase,” he said.
 

It’s all in the gut

One of the ways that drugs like Mounjaro work is by delaying the time that it takes for food to move from the stomach to the small intestine. Although data are still evolving, it is believed that this process – delayed gastric emptying – may affect the absorption of birth control pills. 

Dr. Shah said another theory is that vomiting, which is a common side effect of these types of drugs, also affects the pills’ ability to prevent pregnancy. 

And “there’s a prolonged period of ramping up the dose because of the GI side effects,” said Pinar Kodaman, MD, PhD, a reproductive endocrinologist and assistant professor of gynecology at Yale University in New Haven, Conn. 

“Initially, at the lowest dose, there may not be a lot of potential effect on absorption and gastric emptying. But as the dose goes up, it becomes more common, and it can cause diarrhea, which is another condition that can affect the absorption of any medication,” she said.
 

Unanticipated outcomes, extra prevention

Roughly 42% of women in the United States are obese, 40% of whom are between the ages of 20 and 39. Although these new drugs can improve fertility outcomes for women who are obese (especially those with polycystic ovary syndrome, or PCOS), only one – Mounjaro – currently carries a warning about birth control pill effectiveness on its label. Unfortunately, it appears that some doctors are unaware or not counseling patients about this risk, and the data are unclear about whether other drugs in this class, like Ozempic and Wegovy, have the same risks. 

“To date, it hasn’t been a typical thing that we counsel about,” said Dr. Kodaman. “It’s all fairly new, but when we have patients on birth control pills, we do review other medications that they are on because some can affect efficacy, and it’s something to keep in mind.”

It’s also unclear if other forms of birth control – for example, birth control patches that deliver through the skin – might carry similar pregnancy risks. Dr. Shah said some of his patients who became pregnant without intending to were using these patches. This raises even more questions, since they deliver drugs through the skin directly into the bloodstream and not through the GI system. 

What can women do to help ensure that they don’t become pregnant while using these drugs? 

“I really think that if patients want to protect themselves from an unplanned pregnancy, that as soon as they start the GLP receptor agonists, it wouldn’t be a bad idea to use condoms, because the onset of action is pretty quick,” said Dr. Kodaman, noting also that “at the lowest dose there may not be a lot of potential effect on gastric emptying. But as the dose goes up, it becomes much more common or can cause diarrhea.” 

Dr. Shah said that in his practice he’s “been telling patients to add barrier contraception” 4 weeks before they start their first dose “and at any dose adjustment.”

Zoobia Chaudhry, an obesity medicine doctor and assistant professor of medicine at Johns Hopkins University in Baltimore, recommends that “patients just make sure that the injection and medication that they take are at least 1 hour apart.”

“Most of the time, patients do take birth control before bedtime, so if the two are spaced, it should be OK,” she said.

Another option is for women to speak to their doctors about other contraceptive options like IUDs or implantable rods, where gastric absorption is not going to be an issue. 

“There’s very little research on this class of drugs,” said Emily Goodstein, a 40-year-old small-business owner in Washington, who recently switched from Ozempic to Mounjaro. “Being a person who lives in a larger body is such a horrifying experience because of the way that the world discriminates against you.”

She appreciates the feeling of being proactive that these new drugs grant. It has “opened up a bunch of opportunities for me to be seen as a full individual by the medical establishment,” she said. “I was willing to take the risk, knowing that I would be on these drugs for the rest of my life.”

In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.

“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to. 

Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah. 

Clear conversations are key.

“There’s very little research on this class of drugs,” said Emily Goodstein, a 40-year-old small-business owner in Washington, who recently switched from Ozempic to Mounjaro. “Being a person who lives in a larger body is such a horrifying experience because of the way that the world discriminates against you.”

She appreciates the feeling of being proactive that these new drugs grant. It has “opened up a bunch of opportunities for me to be seen as a full individual by the medical establishment,” she said. “I was willing to take the risk, knowing that I would be on these drugs for the rest of my life.”

In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.

“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to. 

Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah. 

Clear conversations are key.

VANCOUVER – A highly controlled retrospective analysis suggests that denosumab (Prolia) leads to greater reduction in fracture risk than does zoledronic acid (Reclast) among treatment-naive postmenopausal women with osteoporosis.

A previous head-to-head comparison showed that denosumab increased bone mineral density at key skeletal sites compared with zoledronic acid, but only a single, small observational study has examined fracture risk, and it found no difference.

The new study, presented at the annual meeting of the American Society for Bone and Mineral Research, used a relatively new method of real-world comparative effectiveness analysis called negative control outcome (NCO) to analyze Medicare fee-for-service data.

NCO analysis takes extra pains to remove bias through data that might be linked to potential confounders but could not reasonably be attributed to a drug. For example, people who have greater contact with the health care system may be more likely to get one drug or another. The researchers used the frequency of receiving a flu or pneumonia vaccine as a proxy for this. If the two comparison groups had a significant difference in a proxy, it suggested a hidden bias and forced the researchers to abandon those groupings. Another example used car accidents as a proxy for cognitive impairment.

“If you find meaningful differences between the two groups, and you can say there’s no way a bone drug could account for these differences, then we shouldn’t do this analysis because these groups just aren’t comparable. They probably differ by that confounding factor we couldn’t measure,” said Jeffrey Curtis, MD, who presented the study. He is a professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham.

The study strongly suggests superiority for denosumab. “There was a significant difference in multiple different groupings of fractures – beginning at year 2, extending to year 3 and even out to year 5 – that showed that there is a significant reduction in fracture risk if you get treated with denosumab [that was greater] than if you get treated with zoledronic acid,” Dr. Curtis said.

The researchers weighed 118 covariates and ultimately identified a population of 90,805 women taking denosumab and 37,328 taking zoledronic acid that was equally balanced in all patient characteristics. The mean age was about 75 years in the denosumab group and 74 in the zoledronic acid group.

The researchers found a 34% lower risk for hip fracture in the denosumab group by 5 years (relative risk, 0.66; 95% confidence interval, 0.43-0.90).

Similar patterns in fracture risk reduction were observed at 5 years for nonvertebral fracture (RR, 0.67; 95% CI, 0.52-0.82), nonhip nonvertebral fracture (RR, 0.69; 95% CI, 0.50-0.88), and major osteoporotic fracture (RR, 0.74; 95% CI, 0.59-0.89).

During the Q&A session after the talk, one audience member commented that the study was limited because the researchers only followed patients who received zoledronic acid for 60 days, which could have missed potential long-term benefits of the drug, especially since bisphosphonates have a lengthy skeletal retention time. Dr. Curtis acknowledged the point but said, “Usually, that’s not something we do, but these are different enough mechanisms of action that it may be warranted at least as a sensitivity analysis,” he said.

The study and its methodology were impressive, according to Yumie Rhee, MD, who comoderated the session where the study was presented. “I think they did a really good job by doing the negative control analysis. We’re not going to have a head-to-head clinical trial, so we don’t know the real fracture reduction differences [between denosumab and zoledronic acid]. [The NCO analysis] is more than the propensity matching score that we do usually,” said Dr. Rhee, who is a professor of endocrinology at Yonsei University College of Medicine in Seoul, South Korea.

In particular, the study showed a significantly greater reduction in hip fractures with denosumab. “Even in the RCTs, it was really hard to see the reduction in hip fracture, so I think this is showing much stronger data for denosumab. Especially in patients who have more [general fracture] risk and patients with higher hip fracture risk, I would go with denosumab,” Dr. Rhee said.

Her comoderator, Maria Zanchetta, MD, agreed. “It can have clinical implication, because we think denosumab is better than [zoledronic acid] for higher-risk patients, but we didn’t have the evidence. So at least we have a new [study] to look at, and I think it’s very important for our practice,” said Dr. Zanchetta, who is a professor of osteology at the Institute of Diagnostics and Metabolic Research, Universidad del Salvador, Buenos Aires.

The study was funded by Amgen, which markets denosumab. Dr. Curtis has consulted for Amgen. Dr. Rhee and Dr. Zanchetta report no relevant financial relationships.

Lack of time for self-care and rest are particularly harmful to women’s health. Various speakers at the VII National Conference of the Onda Foundation, Italy’s National Observatory for Women and Gender’s Health, focused on this topic. The conference was dedicated to the social factors that determine health within the context of gender medicine.

In our society, housework and raising a family are responsibilities placed predominantly on the shoulders of women. These responsibilities contribute significantly to women’s daily workload. The most overburdened women are working mothers (according to ISTAT, Italy’s Office for National Statistics, 2019), who are forced to combine their professional responsibilities with family life, dedicating 8 hours and 20 minutes per day to paid and unpaid work overall, compared with the 7 hours and 29 minutes spent by working fathers. Working mothers between ages 25 and 44 years have on average 2 hours and 35 minutes of free time per day.
 

Stress and sleep deprivation

“Under these conditions, the risk of chronic stress is raised, and stress leads to depression. The rate of depression in the female population is double that of the male population,” said Claudio Mencacci, MD, chair of the Italian Society of Neuropsychopharmacology and the Onda Foundation. “What’s more, stress increases the risk of cardiovascular and metabolic diseases, asthma, arthritis, and autoimmune diseases.”

The one thing that is especially damaging to physical and mental health is sleep deprivation, and working mothers get less sleep than do working fathers. “This is partially due to biological factors: hormonal changes that take place toward the end of adolescence in women during the premenstrual period are responsible for an increased rate of sleep disturbance and insomnia,” said Dr. Mencacci. “During pregnancy and the postpartum period, female sex hormones make sleep lighter, reducing time spent in the REM sleep stage. Then there’s the social aspect that plays a decisive role: by and large, it’s mothers who take care of the youngest children at night.”

According to a 2019 German study, during the first 6 years of life of the first child, a mother loses on average 44 minutes sleep per night, compared with the average time spent sleeping before pregnancy; a father loses 14 minutes.

“Another aspect to bear in mind is that, for cultural reasons, women tend to overlook the issue and not seek help, deeming sleep deprivation normal,” said Dr. Mencacci.
 

Caregivers at greatest risk

The negative effects of stress are evident in people continuously caring for a dependent older or disabled family member, so-called caregivers. This is, “A group predominantly made up of women aged between 45 and 55 years,” said Marina Petrini, PhD, of the Italian Health Institute’s Gender Medicine Center of Excellence. Dr. Petrini coordinated a study on stress and health in family caregivers.

“The results obtained reveal a high level of stress, especially among female caregivers, who are more exposed to the risk of severe symptoms of depression, physical disorders, especially those affecting the nervous and immune systems, and who tend to adopt irregular eating patterns and sedentary habits,” said Dr. Petrini.
 

Limited treatment access

Another study presented at the Onda Foundation’s conference, which shows just how much a lack of “me time” can damage your health, is the Access to Diagnostic Medicine and Treatment by Region: the Patient’s Perspective Survey, conducted by market research agency Elma Research on a sample of cancer patients requiring specialist treatment.

“Forty percent of them had to move to a different region from the one they live in to get the care they needed,” said Massimo Massagrande, CEO of Elma Research. “Of that group, 40% had to move to an area not neighboring their own. The impact of area of residence is heavy, in terms of money and logistics – so much so that a large proportion of patients interviewed were forced to turn their back on the best available treatments. For women responding to our survey, the biggest obstacle is the impossibility of reconciling the effects of a move or the prospective of a temporary transfer to another region with their responsibilities for looking after their family.”

PHILADELPHIA – Treatment of vasomotor symptoms with estetrol (E4) led to improvements in postmenopausal patients’ lipid profiles and blood glucose, according to findings of a phase 3 clinical trial presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

Participants taking estetrol experienced a decrease in hemoglobin A1c, fasting plasma glucose, total cholesterol, LDL and lipoprotein as well as an increase in HDL cholesterol, according to the findings presented by Wolf Utian, MD, PhD, DSC, a professor emeritus of reproductive biology at Case Western Reserve University, Cleveland, and medical director emeritus of the Menopause Society.

A separate poster at the conference from the same trial also reported significant improvements from estetrol in quality of life, including that related to vasomotor symptoms, and several psychosocial and sexual functioning areas.

Mayo Clinic

E4 is already available as combination oral contraception and is now being considered for treating vasomotor symptoms, explained Chrisandra Shufelt, MD, professor and chair of general internal of medicine and associate director of the Women’s Health Research Center at Mayo Clinic Florida, who was not involved in the study.
 

Background on estetrol

E4 is a human fetal liver estrogen produced during pregnancy that’s synthesized from plants for pharmaceutical use, including as the oral contraceptive drospirenone, Dr. Utian told attendees. It’s classified as a native estrogen with selective tissue activity (NEST), he said.

“E4 is a completely different native estrogen with oral administration mimicking the benefits of transdermals and hence safe and effective,” Dr. Utian said in an interview. “It would be a significant new addition to the pharmaceutical armamentarium.”

Two phase 3 trials presented by Dr. Utian at the same conference last year found estetrol reduced the frequency and severity of moderate to severe vasomotor symptoms, and a previous phase 2 trial finding vasomotor and genitourinary symptom benefits suggested it had potential benefits for lipids, carbohydrate metabolism, and bone turnover.

“In summary, E4 at a daily dose of 15 mg exhibited estrogenic effects in the vagina, leading to improved vaginal health and reduced signs of atrophy, emerging as a promising treatment option not only for vasomotor symptoms but also for other significant menopausal symptoms,” Dr. Utian said. “E4 could offer comprehensive relief for women experiencing a range of menopause-related discomforts.”

Dr. Utian also referenced a 2017 trial in which estetrol positively impacted lipid profiles, “lowering low-density lipoprotein cholesterol, increasing high-density lipoprotein cholesterol, and showing minimal influence on triglycerides,” he said. “Importantly, estetrol was associated with a significant decrease in osteocalcin levels in the higher dose groups, suggesting a potential preventive effect on bone loss,” he added. A recent review of the overall evidence on estetrol suggests its use is “promising,” Dr. Utian noted.
 

Current trial

His current randomized controlled phase 3 trial included postmenopausal women ages 40-65 from 151 sites in 14 countries in Europe, Latin America, and North America, and Russia. Among the 640 participants in the trial, 213 women randomly received 15 mg of estetrol, 213 women received 20 mg of estetrol, and 214 women received a placebo every day for 3 months. All women without hysterectomies also received 200 mg of progesterone once daily for two weeks after completing the estetrol treatment to protect the endometrium.

Researchers took blood samples from the participants at baseline and week 12 to assess total cholesterol, LDL, HDL, the total cholesterol/HDL ratio, triglycerides, lipoprotein A, fasting plasma glucose, insulin, and A1c.

Compared with women in the placebo group, women in both the 15 mg and 20 mg groups saw a statistically significant decrease in lipoprotein A and in the ratio of total cholesterol to HDL, and a statistically significant increase in HDL. Only the women in the 15 mg group saw a statistically significant decrease in LDL and increase in triglycerides; an increase in triglycerides in the 20 mg group did not reach statistical significance.

Statistically significant decreases in fasting plasma glucose and A1c also occurred in both treatment groups, but a decrease in insulin levels and in the homeostasis model-assessment-estimated insulin resistance (HOMA-IR) seen in both treatment arms did not reach significance.

“While the mean changes after 12 weeks from baseline overall were small changes to the cholesterol and blood sugar profiles, they are clinically meaningful because it suggests that E4 does not have any adverse effects to these measures,” Dr. Shufelt said in an interview. “An advantage is that this gives us another hormone option for vasomotor symptoms since it is a native estrogen with selective tissue.”

It’s too early, however, to determine whether estetrol offers benefits in terms of its safety profile, compared with currently available therapies, Dr. Shufelt said.

”These findings of E4 are similar to how oral estradiol changes lipids, which finds an increase in high-density lipoprotein cholesterol, and decreases plasma concentrations of total and low-density lipoprotein cholesterol. an increase in HDL-C and triglycerides and decrease in LDL-C,” she said.
 

Poster findings also promising

For the findings reported in the poster, researchers assessed quality of life and the clinical meaningfulness of vasomotor symptoms’ reduction at baseline and 12 weeks using the Menopause-Specific Quality of Life (MENQOL) questionnaire and the Clinical Global Impression questionnaire, respectively. They also assessed women’s self-reported genitourinary symptoms, including vaginal dryness, pain during urination, vaginal pain and bleeding related to sex, and vaginal or vulvar irritation or itching. Most of these findings primarily confirmed previous positive effects from E4 in other trials.

Women in both the 15 mg and 20 mg estetrol groups reported a statistically significant improvement at 12 weeks, compared with placebo, in their total MENQOL score and in the vasomotor, psychosocial, and sexual functioning domain scores (P < .05). Those in the 20 mg group also had a statistically significant improvement in their physical domain score (P < .05).

Although numerical improvements in genitourinary symptoms occurred at 12 weeks across all three groups, the only statistically significant difference from baseline occurred in patients taking 15 mg of estetrol, who experienced a decrease in vaginal dryness and vaginal pain during sex (P = .0142 and P = .003, respectively).

The Clinical Global Impression questionnaire asked women at 4 and 12 weeks to rate on a seven-item Likert scale their response to this question: “Rate the total improvement, whether or not in your judgment it is due entirely to drug treatment. Compared to your condition at admission to the study, how much has it changed?” Responses of “very much improved” and “much improved” counted as a clinically meaningful difference.

Compared with 27.9% of patients in the placebo group, 52.9% of patients in the 15 mg group and 59.8% of patients in the 20 mg group rated the weekly frequency of moderate to severe vasomotor symptoms as “much improved” or “very much improved” at 4 weeks (P < .0001). At 12 weeks, those numbers rose to 47% in the placebo group, 73.3% in the 15 mg group and 77.8% in the 20 mg group (P < .0001).

The trial’s primary limitation at this point is having only a 12-week follow-up, Dr. Shufelt said, though a few other questions remain.

“Because the two phase 3 RCTs included hysterectomized and nonhysterectomized women, it was unclear how many women in the study had E4 alone versus E4 with progesterone, as that might play a role in both cholesterol and carbohydrate metabolism,” Dr. Shufelt said. “While baseline data was not presented, it would also be important to know baseline values for the women and confirm that none were on lipid-lowering medications.”

PHILADELPHIA – Treatment of vasomotor symptoms with estetrol (E4) led to improvements in postmenopausal patients’ lipid profiles and blood glucose, according to findings of a phase 3 clinical trial presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

Participants taking estetrol experienced a decrease in hemoglobin A1c, fasting plasma glucose, total cholesterol, LDL and lipoprotein as well as an increase in HDL cholesterol, according to the findings presented by Wolf Utian, MD, PhD, DSC, a professor emeritus of reproductive biology at Case Western Reserve University, Cleveland, and medical director emeritus of the Menopause Society.

A separate poster at the conference from the same trial also reported significant improvements from estetrol in quality of life, including that related to vasomotor symptoms, and several psychosocial and sexual functioning areas.

E4 is already available as combination oral contraception and is now being considered for treating vasomotor symptoms, explained Chrisandra Shufelt, MD, professor and chair of general internal of medicine and associate director of the Women’s Health Research Center at Mayo Clinic Florida, who was not involved in the study.
 

Background on estetrol

E4 is a human fetal liver estrogen produced during pregnancy that’s synthesized from plants for pharmaceutical use, including as the oral contraceptive drospirenone, Dr. Utian told attendees. It’s classified as a native estrogen with selective tissue activity (NEST), he said.

“E4 is a completely different native estrogen with oral administration mimicking the benefits of transdermals and hence safe and effective,” Dr. Utian said in an interview. “It would be a significant new addition to the pharmaceutical armamentarium.”

Two phase 3 trials presented by Dr. Utian at the same conference last year found estetrol reduced the frequency and severity of moderate to severe vasomotor symptoms, and a previous phase 2 trial finding vasomotor and genitourinary symptom benefits suggested it had potential benefits for lipids, carbohydrate metabolism, and bone turnover.

“In summary, E4 at a daily dose of 15 mg exhibited estrogenic effects in the vagina, leading to improved vaginal health and reduced signs of atrophy, emerging as a promising treatment option not only for vasomotor symptoms but also for other significant menopausal symptoms,” Dr. Utian said. “E4 could offer comprehensive relief for women experiencing a range of menopause-related discomforts.”

Dr. Utian also referenced a 2017 trial in which estetrol positively impacted lipid profiles, “lowering low-density lipoprotein cholesterol, increasing high-density lipoprotein cholesterol, and showing minimal influence on triglycerides,” he said. “Importantly, estetrol was associated with a significant decrease in osteocalcin levels in the higher dose groups, suggesting a potential preventive effect on bone loss,” he added. A recent review of the overall evidence on estetrol suggests its use is “promising,” Dr. Utian noted.
 

Current trial

His current randomized controlled phase 3 trial included postmenopausal women ages 40-65 from 151 sites in 14 countries in Europe, Latin America, and North America, and Russia. Among the 640 participants in the trial, 213 women randomly received 15 mg of estetrol, 213 women received 20 mg of estetrol, and 214 women received a placebo every day for 3 months. All women without hysterectomies also received 200 mg of progesterone once daily for two weeks after completing the estetrol treatment to protect the endometrium.

Researchers took blood samples from the participants at baseline and week 12 to assess total cholesterol, LDL, HDL, the total cholesterol/HDL ratio, triglycerides, lipoprotein A, fasting plasma glucose, insulin, and A1c.

Compared with women in the placebo group, women in both the 15 mg and 20 mg groups saw a statistically significant decrease in lipoprotein A and in the ratio of total cholesterol to HDL, and a statistically significant increase in HDL. Only the women in the 15 mg group saw a statistically significant decrease in LDL and increase in triglycerides; an increase in triglycerides in the 20 mg group did not reach statistical significance.

Statistically significant decreases in fasting plasma glucose and A1c also occurred in both treatment groups, but a decrease in insulin levels and in the homeostasis model-assessment-estimated insulin resistance (HOMA-IR) seen in both treatment arms did not reach significance.

“While the mean changes after 12 weeks from baseline overall were small changes to the cholesterol and blood sugar profiles, they are clinically meaningful because it suggests that E4 does not have any adverse effects to these measures,” Dr. Shufelt said in an interview. “An advantage is that this gives us another hormone option for vasomotor symptoms since it is a native estrogen with selective tissue.”

It’s too early, however, to determine whether estetrol offers benefits in terms of its safety profile, compared with currently available therapies, Dr. Shufelt said.

”These findings of E4 are similar to how oral estradiol changes lipids, which finds an increase in high-density lipoprotein cholesterol, and decreases plasma concentrations of total and low-density lipoprotein cholesterol. an increase in HDL-C and triglycerides and decrease in LDL-C,” she said.
 

Poster findings also promising

For the findings reported in the poster, researchers assessed quality of life and the clinical meaningfulness of vasomotor symptoms’ reduction at baseline and 12 weeks using the Menopause-Specific Quality of Life (MENQOL) questionnaire and the Clinical Global Impression questionnaire, respectively. They also assessed women’s self-reported genitourinary symptoms, including vaginal dryness, pain during urination, vaginal pain and bleeding related to sex, and vaginal or vulvar irritation or itching. Most of these findings primarily confirmed previous positive effects from E4 in other trials.

Women in both the 15 mg and 20 mg estetrol groups reported a statistically significant improvement at 12 weeks, compared with placebo, in their total MENQOL score and in the vasomotor, psychosocial, and sexual functioning domain scores (P < .05). Those in the 20 mg group also had a statistically significant improvement in their physical domain score (P < .05).

Although numerical improvements in genitourinary symptoms occurred at 12 weeks across all three groups, the only statistically significant difference from baseline occurred in patients taking 15 mg of estetrol, who experienced a decrease in vaginal dryness and vaginal pain during sex (P = .0142 and P = .003, respectively).

Rheumatoid arthritis can’t be cured, but it can significantly improve naturally during pregnancy in 50%-75% of women, prior research has established. It may worsen or stay the same during pregnancy in others.

As of yet, there’s no way to tell which experience a woman with RA will have. RA occurs in 1% of adults globally and is three times more likely to occur in women.

However, a novel study of 19 women with RA suggests that blood biomarkers before pregnancy may predict who will get better or worse during pregnancy. If confirmed with larger studies, the discovery could lead to personalizing medication choices for women with RA who are seeking to become pregnant and change prepregnancy counseling for physicians.

Findings from the research, conducted by first author Matthew Wright, MS, of Children’s Hospital Oakland (Calif.) Research Institute and colleagues were published online in Arthritis Research & Therapy.
 

A risky choice for women

Currently, the choice is difficult because stopping medications during pregnancy could cause disease flare and continuing could risk possible harm to the baby as some of the medications have toxic side effects.

This is the first study to analyze genetic differences in women with RA who plan to get pregnant, senior author Damini Jawaheer, PhD, research associate professor of medicine in rheumatology at Northwestern University, Chicago, said in an interview.

Identifying women who have the disease and confirming they were planning to get pregnant has been extremely difficult, she noted, especially since the start of their research predated electronic health records (EHRs).

The researchers were able to develop a cohort from work they were already doing with researchers in Denmark, which has a national registry that included both women with RA and women of reproductive age. From there they could contact women about their pregnancy intentions and build the cohort for this study.

Healthy women and women with RA of Danish descent who planned to get pregnant were enrolled and were prospectively followed.
 

Genetic differences at prepregnancy baseline

Researchers analyzed genetic differences through RNA sequencing before pregnancy from 19 women with RA and 13 healthy women.

Of the 19 women with RA, disease activity improved during pregnancy in 14 and worsened in 5.

Before pregnancy, the researchers found, several neutrophil-related genes were significantly overexpressed in women whose RA later improved during pregnancy. Genes related to B cells were highly expressed among women who worsened. Those elevated B-cell–related gene levels were not seen in the group who improved during pregnancy, Dr. Jawaheer added.

“We don’t understand at this point why that is,” she said.

They also compared the blood samples with women in the control group who did not have RA.

“Comparisons to healthy women revealed that the B-cell signature was specific” to women with worsened RA, the authors wrote. “Thus, at the prepregnancy stage, the two groups of RA women differed significantly from each other in terms of B-cell function.”
 

Information could help to eliminate fear

Dr. Jawaheer said almost all the women in the cohort who have RA said they were afraid to take medications during pregnancy even if the medications they are taking are considered safe.

“If we could reliably predict who’s going to improve, those women would not have to be scared,” she said. They could stop their medications if they know they’re going to improve naturally.

“Women who are predicted to worsen could then work together with their rheumatologist so that they get treatment to prevent them from getting worse,” Dr. Jawaheer said. “Treatment could be focused on that group only.”

Arthur Kavanaugh, MD, a rheumatologist at University of California San Diego Health and director of the UCSD Center for Innovative Therapy, who was not part of the study, said his patients planning pregnancy struggle with the choices the researchers describe and that investigating potential biomarkers is important.

“Ideally, people would not want to be on anything when they’re pregnant,” he says.

He found the results “intriguing and hypothesis-generating,” but he said the small sample size makes it hard to draw conclusions about the work before it is replicated on a larger scale.

Beth L. Jonas, MD, chief of the division of rheumatology, allergy, and immunology at the University of North Carolina, Chapel Hill, also not a part of the study, said the small study size must be considered, but if the findings are validated in larger studies, the potential is “huge.”

She said doctors used to tell their patients years ago that there’s an excellent chance they will be in remission in pregnancy.

Now, she says, “We’ve tempered our advice to say there’s a good chance you’ll still have disease activity during your pregnancy.”

Rheumatologists would be very interested in a predictive biomarker, she said, as would colleagues in obstetrics/gynecology and maternal-fetal medicine physicians who manage high-risk pregnancies and do prepregnancy counseling.

She said she would also like to see these data followed over multiple pregnancies for each woman, noting that some of her patients have seen RA improve in one pregnancy and worsen in another.

A question she has is, “with a single patient with RA, could you measure this multiple times and get different results?”
 

Tackling the unanswered questions

Next, the researchers want to conduct the study with a larger sample in the United States and one that is more diverse than the Danish cohort, which included only White patients. Now, Dr. Jawaheer and her team will have the help of EHRs.

A big part of Dr. Jawaheer’s lab’s focus is to find out why many with RA report “never feeling better” during pregnancy – some even experience remission – and why women who improve during pregnancy report that their disease flares 3-6 months after pregnancy, she said.

Her team is also studying what happens biologically when some women worsen in pregnancy.

Those answers “will give us an indication of what could be a potential drug target,” she said.

The authors and Dr. Kavanaugh and Dr. Jonas reported no relevant financial relationships.

The US Department of Veterans Affairs (VA) provides health care to about 600,000 women veterans—half are of child-bearing age. Pregnancies in women veterans using VA care have increased by more than 80% since 2014, from 6950 in 2014 to 12,524 in 2022.

Until recently, VA maternity care coordinators would help women navigate health care from the beginning of pregnancy to 8 weeks postpartum. But “[e]vidence shows that new mothers often need support and care coordination long after 8 weeks postpartum, which is why VA is taking action to support veteran mothers for much longer after they give birth,” said Under Secretary for Health Shereef Elnahal, MD. As of October 1, 2023, the maternity support is now extended to 12 months postpartum.

The full range of maternity care services includes primary care, examinations, tests, ultrasounds, newborn care, and screening for social determinants of health, mental health risk factors, and relationship health and safety. Maternity care coordinators also connect veterans with care after delivery and ensure access to follow-up screenings.

The VA says expanding access to maternity care coordinators is part of the work it’s doing to implement the White House Blueprint for Addressing the Maternal Health Crisis, released last year. The US maternal mortality rate is the highest of any developed nation in the world and more than double the rate of peer countries, the report says. According to the Centers for Disease Control and Prevention (CDC), from 2018 to 2021, the maternal death rate in the US increased from 17.4 to 32.9 per 100,000 live births.

Moreover, “[t]housands of women experience unexpected outcomes of labor and delivery that result in significant short- or long-term consequences to their health,” the White House report says, “such as heart issues, the need for blood transfusions, eclampsia, and blood infections.” Disturbingly, more than 80% of pregnancy-related deaths are preventable. Black and American Indian/Alaska Native women, regardless of income or education, are most likely to experience poor outcomes. Women who live in rural America—where there are many maternal care “deserts”—are about 60% more likely to die, the White House report says.

Quality care requires “care organized for and provided to all women in a manner that maintains their dignity, privacy, and confidentiality, ensures freedom from harm and mistreatment, and enables informed choice and con­tinuous support during labor and childbirth,” say CDC researchers who surveyed 2407 women about their maternity care experiences. One in 5 respondents reported instances of mistreatment. Roughly one-third of Black, Hispanic, and multiracial women reported, for instance, receiving no response to requests for help, being shouted at or scolded, not having their physical privacy protected, and being threatened with withholding treatment or made to accept unwanted treatment.

The White House Blueprint delineates several goals. One is to ”ensure those giving birth are heard and are decisionmakers in accountable systems of care…to improve quality of care, hold providers accountable, and prioritize patient needs and their experience before, during, and after pregnancy.”

The Blueprint advises, for instance, expanding the Hear Her campaign to include culturally relevant materials to raise awareness of urgent maternal warning signs and improve communication between patients and clinicians. It also urges addressing social determinants of maternal health, supporting projects to expand maternal mental health access, increasing access to digital tools, and expanding models that train maternal health care practitoners and students on how to address implicit bias and racism and screen for social determinants of health.

Answering its question of “how we get there,” the Blueprint says, “In working toward this vision, the Biden-Harris Administration has developed, for the first time, a national, whole-of-government strategy to address our maternal health crisis. This strategy starts with the recognition that a concerted national effort to solve the crisis must begin with clear leadership and action from across the federal government. Addressing the maternal health crisis is not limited to a single health care policy or federal agency but should include experts across the government, including: the US Departments of Health and Human Services, Agriculture, Defense, Housing and Urban Development, Labor, Justice, Environmental Protection Agency, Office of Personnel Management, as well as the VA.

“The Biden-Harris Administration believes that only through this whole-of-government approach—one that considers the entirety of a person’s health and experiences over the course of their full life—will we finally be able to make real progress in tackling this longstanding challenge.”

I had a case come to me of a 32-year-old resident who works in a hospital near where I am and was very interested in freezing her eggs. She wasn’t married and was getting worried that maybe she wouldn’t have a partner soon. She was also getting worried that the potential ability of her eggs to be fertilized would begin to decline, which is a phenomenon that does occur with age. She thought, I’m 32; maybe I should freeze my eggs now, as it’s better than to try freezing them when I’m 35 or 37. The potency may be far less.

There are many programs out there now. There have been academic programs for a long time that have been doing egg freezing, and there are many children who have been born successfully. However, it’s also true that people freeze their eggs when they’re 40 years old, and the likelihood of their “working,” if you will, is far less. I wouldn’t say it’s impossible, but age matters. This medical resident knew that and she decided to look into egg freezing.

Well, it turned out that egg freezing is not something that her student insurance plan – or most insurance plans in general – covers. The opportunity to do this is probably going to cost her about $10,000. There are many new egg-freezing infertility programs that have stared up that aren’t part of hospitals. There are clinics that are run for profit. They sometimes encourage women to freeze their eggs.

The student resident quickly found out that there were companies near her who would do egg freezing but would cut a deal if she agreed to take drugs to super-ovulate, make a large number of eggs, and they would be procured if she agreed to give half of them to other women who needed eggs for their infertility treatment. She could keep half and she could get very discounted treatment of egg freezing. In other words, she could barter her own eggs, said the clinic, if she was willing to accept the idea that she’d be donating them to others.

That may be a deal that she’s going to accept. She doesn’t have a path forward. She’s worried about freezing her eggs right now. But there are many ethical considerations that really have to be thought through here.

First and foremost, she’s giving eggs to others. They’re going to use them to try to make children. They can’t make their own eggs, for some reason. She’s going to have some biologically related kids out there. It used to be that you could say to someone who donated sperm or eggs that this will be anonymous.

But in today’s day and age with 23andMe, Ancestry, and better genetic testing, there’s a pretty good likelihood that somebody is going to find out that the person they thought was their biological mom isn’t, and they have someone out there who was the person who, in this case, donated an egg.

Is she willing to risk having that connection, that contact, to have someone enter her life in the future? It’s a situation where she’s donating the eggs, but I’ll tell you that the clinic is going to make far more money using the donated eggs, probably getting $10,000 or $15,000 a cycle with people who are trying to have a child. They’ll make much more money than she’s going to get by donating.

She may get a $5,000 discount, if you will, but the clinic has a business interest. The more they get women involved in bartering their eggs, the more they’re going to profit. In a sense, she’s being coerced, perhaps – I’m going to put it glibly – to sell cheaply. She probably is getting undervalue, even though she needs a path to do this egg freezing.

The other big issue is that we don’t know that egg freezing is going to work for her until someone tries to use those eggs. She may have her own infertility problem not due to age but to other things. Approximately 8%-9% of couples do have infertility problems, sometimes related to gametes. She may never get a partner. Maybe she doesn’t want to use these eggs on her own as a single mom. All of these issues have to be talked through.

What really troubles me here is not so much that someone would choose to barter their eggs, but that they don’t get counseling. They don’t get independent advice about thinking this all through. It’s turning into a business. A business has a commodity – her eggs – that they want. She’s getting more and more desperate, willing to cut a deal to get where she needs to be, but perhaps is not really thinking through all of the ethical dimensions that bartering or trading one’s eggs in order to gain access to freezing entails.

We have to set up a system where there’s independent advice and independent counseling; otherwise, I think we’re closer to exploitation.

According to research results published in the American Journal of Obstetrics and Gynecology, consuming a primarily plant-based diet is associated with a lower risk of developing hypertensive disorders of pregnancy.
 

The prospective cohort study followed 11,459 women older than 18 years and evaluated their diet from the beginning using a validated questionnaire about the frequency and quality of plant-based foods. The participants had taken part in the Nurses’ Health Study II (1991-2009). From responses on the questionnaire, the investigators calculated the plant-based diet index (PDI) even among participants with an omnivorous diet. A higher score indicated greater adherence to the PDI.

“We wanted to know how one’s diet leading up to pregnancy influences the pregnancy, so we monitored women for virtually their entire reproductive life – almost 20 years – and gained an awareness of their typical diet before pregnancy,” study author Jorge E. Chavarro, MD, ScD, told this news organization. Dr. Chavarro is a professor of nutrition, epidemiology, and medicine at Harvard Medical School, Boston, and Harvard University’s School of Public Health in Cambridge, Mass. He researches how nutrition and lifestyle influence reproductive health and overall lifelong health in women.

Analysis of the data from the Nurses’ Health Study II revealed that as the proportion of animal products in diets decreased and the proportion of plant-based products increased, the risk of women experiencing hypertensive disorders of pregnancy decreased as well. Women in the highest PDI quintile had a significantly lower risk of hypertensive disorders of pregnancy, in comparison with those in the lowest quintile (relative risk, 0.76). This association was slightly stronger for pregnancy-related hypertension (RR, 0.77) than for preeclampsia (RR, 0.80).

Women in the highest PDI quintile had a 24% lower risk of hypertensive disorders of pregnancy than those in the lowest quintile; the risk of pregnancy-related hypertension decreased in a linear fashion as PDI increased, while the relationship of PDI to preeclampsia was restricted to women in the quintile with the highest adherence.

“It was clearer for pregnancy-related hypertension than for preeclampsia, but a diet made up primarily of plant-based foods seemed to be protective for both,” said Dr. Chavarro. He added that in addition to the problems these conditions cause during pregnancy, both increase the risk of subsequently developing other chronic diseases. “Could it be that modifiable lifestyle factors before and during pregnancy may not only help reduce problems during gestation but also prevent women’s health problems years later? That was the general motivation for this study.”

Mercedes Sotos-Prieto, PhD, a researcher at the Autonomous University of Madrid and an associate professor at Harvard University’s School of Public Health, told this news organization that the study’s methodology was very robust and that the investigators utilized appropriate statistical techniques for the analysis. She highlighted the fact that they used a validated food frequency questionnaire. She believes the study is also important because of the population group it focused on. “There has always been greater resistance when it comes to the diet of pregnant women, and the same is true for older adults. But we have seen that this type of diet, if it’s a quality diet, may be associated with health benefits.” She did not participate in the study.

Dr. Sotos-Prieto has a doctorate in nutritional epidemiology and public health. She works with large epidemiologic cohorts, such as the cohort of American nurses on which this study was based, and ENRICA, a cohort that is representative of the Spanish population and the population of older adults. She is the author of other studies that, like this one, found an association between a plant-based diet and a lower risk of frailty, both in the study involving American nurses and in a study involving a cohort of individuals aged 60 years or older in Spain (ENRICA-1).

Dr. Sotos-Prieto is also principal investigator on a project assessing the risk of cardiovascular disease based on modifiable lifestyles. For this project, the researchers created a tool, the healthy heart test, that can be used to evaluate diet quality “in 5 minutes, because we all know that doctors don’t have any time.” She thinks this test could be implemented in clinical practice to identify lifestyle behaviors that can be improved, such as by replacing refined cereals with whole grains or increasing legume consumption.
 

Tomatoes and French fries

The greatest benefit of a plant-based diet comes from the diet overall, not from any single food item. That said, these studies use a scoring system to reflect which items are healthy and which are not.

Diet was assessed every 4 years, starting in 1991, using a semiquantitative food frequency questionnaire that recorded the consumption of 131 foods and drinks during the previous year. The researchers determined the average frequency with which participants consumed each food. Eighteen food groups were sorted into three categories: healthy plant-based foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils, tea, and coffee), unhealthy plant-based foods (fruit juices, refined grains, potatoes, sugary drinks, sweets, and desserts), and animal-based foods (dairy, eggs, fish or shellfish, meat, and various foods of animal origin).

Healthy plant-based foods were given positive scores, while less healthy plant-based foods and the animal-based food groups were given negative scores. The consumption of each food group was classified into PDI using quintiles.

Women in the highest PDI quintile had a significantly lower risk for hypertensive disorders of pregnancy, compared with women in the lowest quintile. There was a negative dose-response relationship between PDI and risk of the disease. “A vegetarian diet isn’t necessarily healthier than a nonvegetarian diet if it’s made up of superfluous foods like French fries and soft drinks,” said Dr. Sotos-Prieto. “The difference lies in the quality of the plant-based foods. That’s what makes the difference between a healthy and an unhealthy diet.”
 

Give up meat?

Dr. Chavarro said that removing meat from his dinner menu 22 years ago was one of the hardest things he ever did. “Now, it’s no problem,” he said. But he understands that there are people for whom changing the diet by replacing animal products with nonanimal products is difficult. But meat need not be entirely abandoned.

“The women in the highest quintile aren’t necessarily vegetarian or vegan, but they consume much fewer animal-based foods than the others,” he noted. He added that vegetarian or vegan diets are not incompatible with a healthy pregnancy. “All vegans know how to get vitamin B12 from supplements.”
 

Diet or weight loss?

Much of the benefit observed in the study appears to be related to better weight control. The body mass index between dietary assessment and pregnancy accounted for 39% of the relationship between PDI and hypertensive disorders of pregnancy and 48% of the relationship between PDI and pregnancy-related hypertension.

“Part of the association seems to be explained by better weight control over long periods,” explained Dr. Chavarro. Women who adopted diets with more plant-based foods gained weight more slowly than those who consumed more animal-based foods. “They are different in terms of their weight trajectory over many years. So, part of the association that we observe is related to better long-term weight control. But the other half of the association is attributable to the diet itself and not necessarily to weight.” The authors suggest mechanisms of action such as endothelial dysfunction, inflammation, or blood pressure before pregnancy to explain the association.

Dr. Sotos-Prieto believes that this point is “extremely relevant.” In her opinion, it reveals that controlling weight at the start of pregnancy is important for pregnant women. Weight control may also improve other factors, like gestational diabetes. “I think preventive measures should focus on that. These results show that interventions are needed to increase the likelihood of going into pregnancy with an appropriate weight. And this includes modifying diet.”
 

Generalizable results?

More than 90% of the participants in the Nurses’ Health Study were White, not Hispanic. Can the results be extrapolated to other populations? “The answer: The study needs to be repeated in other populations,” said Dr. Chavarro, “and that’s going to take time. But even without that information, I think we can use this study to inform other populations, regardless of ethnicity.”

Dr. Sotos-Prieto admitted that this hypothesis has not yet been tested in the Spanish population, but she is the author of a similar study that followed nearly 12,000 Spanish adults for a decade using the same PDI. In this study, every 10-point increase in PDI was associated with a 14% lower risk of mortality from any cause (hazard ratio, 0.86) and a 37% lower risk of death from cardiovascular disease (HR, 0.63). She also believes that the recommendations derived from the study could be generalized to other populations “as long as each country’s culture is taken into account, to see how it can be culturally adapted. If it’s a population that consumes a lot of refined cereals, for example, make small changes to whole grains.”
 

Weighing the evidence

The study has strengths and limitations, owing to its methodology, and Dr. Chavarro himself recognizes that “in terms of hypertensive disorders of pregnancy specifically, this won’t be the last word.” But there is a pressing need to find answers.

The American College of Obstetricians and Gynecologists and the World Health Organization encourage women to follow healthy diets before and during pregnancy. But they provide little guidance on what constitutes a healthy diet when it comes to minimizing the risks of adverse pregnancy outcomes. “They are quite ambiguous and vague,” said Dr. Chavarro.

These new findings suggest that plant-based diets may be one such strategy, particularly because some evidence was found that these diets may be beneficial for women older than 35 years, who are considered a high-risk group.

“There are certainly many ways to eat healthily, but if we think about these pregnancy complications that can have serious consequences for the mother and the fetus, we might consider this as a healthy diet option,” Dr. Chavarro noted.

But is the evidence robust enough to recommend that patients make changes? “Ideally, there will be more studies,” stated Dr. Chavarro. “There are two ways to understand the problem. One is not making recommendations until you have three controlled clinical trials, which, even with the willingness and funding to do so, will take 15-20 years. But if we have to provide the best available information to those who need it today, I think these are solid results for guiding behavior.

“It’s always better if we can make decisions based on solid, incontrovertible information. But it’s not always available, and you must learn to live in both worlds and make decisions with uncertainties,” he concluded.

Dr. Sotos-Prieto and Dr. Chavarro have disclosed no relevant financial relationships.

According to research results published in the American Journal of Obstetrics and Gynecology, consuming a primarily plant-based diet is associated with a lower risk of developing hypertensive disorders of pregnancy.
 

The prospective cohort study followed 11,459 women older than 18 years and evaluated their diet from the beginning using a validated questionnaire about the frequency and quality of plant-based foods. The participants had taken part in the Nurses’ Health Study II (1991-2009). From responses on the questionnaire, the investigators calculated the plant-based diet index (PDI) even among participants with an omnivorous diet. A higher score indicated greater adherence to the PDI.

“We wanted to know how one’s diet leading up to pregnancy influences the pregnancy, so we monitored women for virtually their entire reproductive life – almost 20 years – and gained an awareness of their typical diet before pregnancy,” study author Jorge E. Chavarro, MD, ScD, told this news organization. Dr. Chavarro is a professor of nutrition, epidemiology, and medicine at Harvard Medical School, Boston, and Harvard University’s School of Public Health in Cambridge, Mass. He researches how nutrition and lifestyle influence reproductive health and overall lifelong health in women.

Analysis of the data from the Nurses’ Health Study II revealed that as the proportion of animal products in diets decreased and the proportion of plant-based products increased, the risk of women experiencing hypertensive disorders of pregnancy decreased as well. Women in the highest PDI quintile had a significantly lower risk of hypertensive disorders of pregnancy, in comparison with those in the lowest quintile (relative risk, 0.76). This association was slightly stronger for pregnancy-related hypertension (RR, 0.77) than for preeclampsia (RR, 0.80).

Women in the highest PDI quintile had a 24% lower risk of hypertensive disorders of pregnancy than those in the lowest quintile; the risk of pregnancy-related hypertension decreased in a linear fashion as PDI increased, while the relationship of PDI to preeclampsia was restricted to women in the quintile with the highest adherence.

“It was clearer for pregnancy-related hypertension than for preeclampsia, but a diet made up primarily of plant-based foods seemed to be protective for both,” said Dr. Chavarro. He added that in addition to the problems these conditions cause during pregnancy, both increase the risk of subsequently developing other chronic diseases. “Could it be that modifiable lifestyle factors before and during pregnancy may not only help reduce problems during gestation but also prevent women’s health problems years later? That was the general motivation for this study.”

Mercedes Sotos-Prieto, PhD, a researcher at the Autonomous University of Madrid and an associate professor at Harvard University’s School of Public Health, told this news organization that the study’s methodology was very robust and that the investigators utilized appropriate statistical techniques for the analysis. She highlighted the fact that they used a validated food frequency questionnaire. She believes the study is also important because of the population group it focused on. “There has always been greater resistance when it comes to the diet of pregnant women, and the same is true for older adults. But we have seen that this type of diet, if it’s a quality diet, may be associated with health benefits.” She did not participate in the study.

Dr. Sotos-Prieto has a doctorate in nutritional epidemiology and public health. She works with large epidemiologic cohorts, such as the cohort of American nurses on which this study was based, and ENRICA, a cohort that is representative of the Spanish population and the population of older adults. She is the author of other studies that, like this one, found an association between a plant-based diet and a lower risk of frailty, both in the study involving American nurses and in a study involving a cohort of individuals aged 60 years or older in Spain (ENRICA-1).

Dr. Sotos-Prieto is also principal investigator on a project assessing the risk of cardiovascular disease based on modifiable lifestyles. For this project, the researchers created a tool, the healthy heart test, that can be used to evaluate diet quality “in 5 minutes, because we all know that doctors don’t have any time.” She thinks this test could be implemented in clinical practice to identify lifestyle behaviors that can be improved, such as by replacing refined cereals with whole grains or increasing legume consumption.
 

Tomatoes and French fries

The greatest benefit of a plant-based diet comes from the diet overall, not from any single food item. That said, these studies use a scoring system to reflect which items are healthy and which are not.

Diet was assessed every 4 years, starting in 1991, using a semiquantitative food frequency questionnaire that recorded the consumption of 131 foods and drinks during the previous year. The researchers determined the average frequency with which participants consumed each food. Eighteen food groups were sorted into three categories: healthy plant-based foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils, tea, and coffee), unhealthy plant-based foods (fruit juices, refined grains, potatoes, sugary drinks, sweets, and desserts), and animal-based foods (dairy, eggs, fish or shellfish, meat, and various foods of animal origin).

Healthy plant-based foods were given positive scores, while less healthy plant-based foods and the animal-based food groups were given negative scores. The consumption of each food group was classified into PDI using quintiles.

Women in the highest PDI quintile had a significantly lower risk for hypertensive disorders of pregnancy, compared with women in the lowest quintile. There was a negative dose-response relationship between PDI and risk of the disease. “A vegetarian diet isn’t necessarily healthier than a nonvegetarian diet if it’s made up of superfluous foods like French fries and soft drinks,” said Dr. Sotos-Prieto. “The difference lies in the quality of the plant-based foods. That’s what makes the difference between a healthy and an unhealthy diet.”
 

Give up meat?

Dr. Chavarro said that removing meat from his dinner menu 22 years ago was one of the hardest things he ever did. “Now, it’s no problem,” he said. But he understands that there are people for whom changing the diet by replacing animal products with nonanimal products is difficult. But meat need not be entirely abandoned.

“The women in the highest quintile aren’t necessarily vegetarian or vegan, but they consume much fewer animal-based foods than the others,” he noted. He added that vegetarian or vegan diets are not incompatible with a healthy pregnancy. “All vegans know how to get vitamin B12 from supplements.”
 

Diet or weight loss?

Much of the benefit observed in the study appears to be related to better weight control. The body mass index between dietary assessment and pregnancy accounted for 39% of the relationship between PDI and hypertensive disorders of pregnancy and 48% of the relationship between PDI and pregnancy-related hypertension.
