Menopause

The Food and Drug Administration has approved the oral medication fezolinetant (Veozah) for the treatment of moderate to severe hot flashes in menopausal women, according to an FDA statement. The approved dose is 45 mg once daily.

Fezolinetant, a neurokinin 3 (NK3) receptor antagonist, is the first drug of its kind to earn FDA approval for the vasomotor symptoms associated with menopause, according to the statement. The drug works by binding to the NK3 receptor, which plays a role in regulating body temperature, and blocking its activity. Fezolinetant is not a hormone, and can be taken by women for whom hormones are contraindicated, such as those with a history of vaginal bleeding, stroke, heart attack, blood clots, or liver disease, the FDA stated.

The approval was based on data from the SKYLIGHT 2 trial, results of which were presented at the annual meeting of the Endocrine Society, reported by this news organization, and published in the Journal of Clinical Endocrinology and Metabolism.

In the two-phase trial, women were randomized to 30 mg or 45 mg of fezolinetant or a placebo. After 12 weeks, women in placebo groups were rerandomized to fezolinetant for a 40-week safety study.

The study population included women aged 40-65 years, with an average minimum of seven moderate-to-severe hot flashes per day. The study included 120 sites in North America and Europe.

At 12 weeks, both placebo and fezolinetant patients experienced reductions in moderate to severe vasomotor symptoms of approximately 60%, as well as a significant decrease in vasomotor symptom severity.

The FDA statement noted that patients should undergo baseline blood work before starting fezolinetant to test for liver infection or damage, and the prescribing information includes a warning for liver injury; blood work should be repeated at 3, 6, and 9 months after starting the medication, according to the FDA and a press release from the manufacturer Astellas.

The most common side effects associated with fezolinetant include abdominal pain, diarrhea, insomnia, back pain, hot flashes, and elevated liver values, according to the FDA statement. The FDA granted Astellas Pharma’s application a Priority Review designation. Astellas has priced the drug at $550 for a 30-day supply, significantly higher than the Institute for Clinical and Economic Review’s previously recommended range of $2,000 to $2,500 per year.

In postmenopausal women with hormone receptor–positive breast cancer, overweight and obesity were overall predictors of lower disease-free survival, but body mass index had no apparent association with the effect of extended endocrine therapy on disease-free survival, new data suggest.

Obesity is a well-known risk factor for breast cancer in postmenopausal women and has been associated with adverse prognosis, said Senna W.M. Lammers, MD, of Maastricht (the Netherlands) University during a presentation at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress. In addition, some studies suggest that patients with higher body mass index (BMI) experience reduced benefits from endocrine therapy, she said.

Dr. Lammers and colleagues conducted a study to determine the prognostic and predictive effect of BMI on disease-free survival in postmenopausal women with hormone receptor–positive (HR+) breast cancer who were treated with extended endocrine therapy.

The study population included participants in the randomized, phase III DATA trial, which evaluated the use of 6 years vs. 3 years of anastrozole in postmenopausal women with HR+ breast cancer who were disease-free after 2-3 years of adjuvant tamoxifen therapy.

Patients were categorized based on BMI as having normal weight (18.5-24.9 kg/m²), overweight (25-29.9 kg/m²), or obese (30 kg/m² or higher). The primary outcome was disease-free survival (DFS); the median follow-up period was 13.1 years.

DFS for patients with normal weight, overweight, and obesity was 66.2%, 59.5%, and 52.4%, with a P value of less than .001 for the trend, Dr. Lammers said. “These results were confirmed in multivariable analysis,” she said. Overall, patients with overweight and obesity had a worse DFS when compared with patients with normal weight (hazard ratio, 1.16; P = .10, for patients with overweight and HR, 1.26; P = .03 for patients with obesity).

“Next, we aimed to determine whether the prognostic effect of BMI differed by age,” Dr. Lammers said.

In women younger than 60 years, overweight and obesity were significantly associated with worse DFS (HR, 1.29; P = .05 and HR 1.83, P less than .001, respectively). However, this effect was not observed in women aged 60 years and older.

The researchers also examined the treatment effect of extended anastrozole on adapted DFS by weight, and found no significant differences among patients with normal weight, overweight, and obesity (HR, 1.00; HR, 0.74; and HR, 0.97, respectively), said Dr. Lammers.

In the question and answer session, Dr. Lammers was asked about possible explanations for the difference in DFS by age. Potential explanations include possible survival bias “as only the healthier [patients with obesity] survive to old age,” she said. Other potential explanations are biological, such as the potentially higher levels of bone density in older [patients with obesity], she said.

When asked about additional clinical implications, Dr. Lammers emphasized the importance of maintaining a healthy BMI for breast cancer patients of all ages. Other research areas might involve the use of lifestyle interventions, although these are challenging to implement, she noted.
 

Data draw attention to quality of life and lifestyle factors

The need to “look at drug development with new eyes” is particularly important when reviewing patient-reported outcomes, said Otto Metzger, MD, of the Dana Farber Cancer Institute, Boston, who served as the discussant for the session.

Dr. Metzger brought up the association between age and the effect of BMI on DFS, specifically.

Based on data from multiple studies and meta-analyses, “I do believe that obesity does play a role in prognosis,” he said, but the question is how long will researchers continue to simply record data without acting to add lifestyle interventions while also trying to develop new drugs, he said. Although convincing patients to make lifestyle changes remains a challenge, patients are often more motivated to make such changes after a cancer diagnosis, Dr. Metzger noted.

“I am a firm believer in the use of digital therapeutics in the context of clinical trials,” said Dr. Metzger. Digital technology offers great potential to educate patients on [adverse effects] and also to improve treatment adherence and quality of life, he concluded.

The study was supported by AstraZeneca, and Dr. Lammers disclosed financial relationships with AstraZeneca and Eli Lilly. Dr. Metzger disclosed receiving research funding to his institution from Pfizer, Genentech/Roche, and Sanofi, and serving as an adviser/consultant to AstraZeneca, Merck, Oncoclinicas, Resilience, and Roche.

PHOENIX – While the use of lasers and energy-based devices for genitourinary indications dates back more than 50 years, a large body of scientific evidence has since accumulated for conditions ranging from genitourinary syndrome of menopause (GSM), lichen sclerosus, urinary incontinence, and vulvovaginal laxity.

“Even a cursory review of PubMed today yields over 100,000 results” on this topic, Macrene R. Alexiades, MD, PhD, associate clinical professor of dermatology at Yale University, New Haven, Conn., said at the annual conference of the American Society for Laser Medicine and Surgery. “Add to that radiofrequency and various diagnoses, the number of publications has skyrocketed, particularly over the last 10 years.”

What has been missing from this hot research topic all these years, she continued, is that no one has distilled this pile of data into a practical guide for office-based clinicians who use lasers and energy-based devices for genitourinary conditions – until now. Working with experts in gynecology and urogynecology, Dr. Alexiades spearheaded a 2-year-long effort to assemble a document on optimal protocols and best practices for genitourinary application of lasers and energy-based devices. The document, published soon after the ASLMS meeting in Lasers in Medicine and Surgery, includes a table that lists the current Food and Drug Administration approval status of devices in genitourinary applications, as well as individual sections dedicated to fractional lasers, radiofrequency (RF) devices, and high-intensity focused electromagnetic technology. It concludes with a section on the current status of clearances and future pathways.

“The work we did was exhaustive,” said Dr. Alexiades, who is also founder and director of Dermatology & Laser Surgery Center of New York. “We went through all the clinical trial data and compiled the parameters that, as a consensus, we agree are best practices for each technology for which we had rigorous published data.”

The document contains a brief background on the history of the devices used for genitourinary issues and it addresses core topics for each technology, such as conditions treated, contraindications, preoperative physical assessment and preparation, perioperative protocols, and postoperative care.

Contraindications to the genitourinary use of lasers and energy-based devices are numerous and include use of an intrauterine device, active urinary tract or genital infection, vaginal bleeding, current pregnancy, active or recent malignancy, having an electrical implant anywhere in the body, significant concurrent illness, and an anticoagulative or thromboembolic condition or taking anticoagulant medications 1 week prior to the procedure. Another condition to screen for is advanced prolapse, which was considered a contraindication in all clinical trials, she added. “It’s important that you’re able to do the speculum exam and stage the prolapse” so that a patient with this contraindication is not treated.

Dr. Alexiades shared the following highlights from the document’s section related to the use of fractional CO₂ lasers:

Preoperative management. Schedule the treatment one week after the patient’s menstrual period. Patients should avoid blood thinners for 7 days and avoid intercourse the night before the procedure. Reschedule in the case of fever, chills, or vaginal bleeding or discharge.

Preoperative physical exam and testing. A normal speculum exam and a recent negative PAP smear are required. For those of child-bearing potential, a pregnancy test is warranted. Obtain written and verbal consent, including discussion of all treatment options, risks, and benefits. No topical or local anesthesia is necessary internally. “Externally, we sometimes apply topical lidocaine gel, but I have found that’s not necessary in most cases,” Dr. Alexiades said. “The treatment is so quick.”

Peri-operative management. In general, device settings are provided by the manufacturer. “For most of the studies that had successful outcomes and no adverse events, researchers adhered to the mild or moderate settings on the technology,” she said. Energy settings were between 15 and 30 watts, delivered at a laser fluence of about 250-300 mJ/cm² with a spacing of microbeams 1 mm apart. Typically, three treatments are done at 1-month intervals and maintenance treatments are recommended at 6 and 12 months based on duration of the outcomes.

Vulvovaginal postoperative management. A 3-day recovery time is recommended with avoidance of intercourse during this period, because “re-epithelialization is usually complete in 3 days, so we want to give the opportunity for the lining to heal prior to introducing any friction, Dr. Alexiades said.” Rarely, spotting or discharge may occur and there should be no discomfort. “Any severe discomfort or burning may potentially signify infection and should prompt evaluation and possibly vaginal cultures. The patient can shower, but we recommend avoiding seated baths to decrease any introduction of infectious agents.”

Patients should be followed up monthly until three treatments are completed, and a maintenance treatment is considered appropriate between 6 and 12 months. “I do recommend doing a 1-month follow-up following the final treatment, unless it’s a patient who has already had a series of three treatments and is coming in for maintenance,” she said.

In a study from her own practice, Dr. Alexiades evaluated a series of three fractional CO₂ laser treatments to the vulva and vagina with a 1-year follow-up in postmenopausal patients. She used the Vaginal Health Index (VHI) to assess changes in vaginal elasticity, fluid volume, vaginal pH, epithelial integrity, and moisture. She and her colleagues discovered that there was improvement in every VHI category after treatment and during the follow-up interval up to 6 months.

“Between 6 and 12 months, we started to see a return a bit toward baseline on all of these parameters,” she said. “The serendipitous discovery that I made during the course of that study was that early intervention improves outcomes. I observed that the younger, most recently postmenopausal cohort seemed to attain normal or near normal VHI quicker than the more extended postmenopausal cohorts.”

In an editorial published in 2020, Dr. Alexiades reviewed the effects of fractional CO₂ laser treatment of vulvar skin on vaginal pH and referred to a study she conducted that found that the mean baseline pH pretreatment was 6.32 in the cohort of postmenopausal patients, and was reduced after 3 treatments. “Postmenopausally, the normal acidic pH becomes alkaline,” she said. But she did not expect to see an additional reduction in pH following the treatment out to 6 months. “This indicates that, whatever the wound healing and other restorative effects of these devices are, they seem to continue out to 6 months, at which point it turns around and moves toward baseline [levels].”

Dr. Alexiades highlighted two published meta-analyses of studies related to the genitourinary use of lasers and energy-based devices. One included 59 studies of 3,609 women treated for vaginal rejuvenation using either radiofrequency or fractional ablative laser therapy. The studies reported improvements in symptoms of GSM/VVA and sexual function, high patient satisfaction, with minor adverse events, including treatment-associated vaginal swelling or vaginal discharge.

“Further research needs to be completed to determine which specific pathologies can be treated, if maintenance treatment is necessary, and long-term safety concerns,” the authors concluded.

In another review, researchers analyzed 64 studies related to vaginal laser therapy for GSM. Of these, 47 were before and after studies without a control group, 10 were controlled intervention studies, and 7 were observational cohort and cross-sectional studies.

Vaginal laser treatment “seems to improve scores on the visual analogue scale, Female Sexual Function Index, and the Vaginal Health Index over the short term,” the authors wrote. “Safety outcomes are underreported and short term. Further well-designed clinical trials with sham-laser control groups and evaluating objective variables are needed to provide the best evidence on efficacy.”

“Lasers and energy-based devices are now considered alternative therapeutic modalities for genitourinary conditions,” Dr. Alexiades concluded. “The shortcomings in the literature with respect to lasers and device treatments demonstrate the need for the consensus on best practices and protocols.”

During a separate presentation at the meeting, Michael Gold, MD, highlighted data from Grand View Research, a market research database, which estimated that the global women’s health and wellness market is valued at more than $31 billion globally and is expected to grow at a compound annual growth rate of 4.8% from 2022 to 2030.

“Sales of women’s health energy-based devices continue to grow as new technologies are developed,” said Dr. Gold, a Nashville, Tenn.–based dermatologist and cosmetic surgeon who is also editor-in-chief of the Journal of Cosmetic Dermatology. “Evolving societal norms have made discussions about feminine health issues acceptable. Suffering in silence is no longer necessary or advocated.”

Dr. Alexiades disclosed that she has conducted research for Candela Lasers, Lumenis, Allergan/AbbVie, InMode, and Endymed. She is also the founder and CEO of Macrene Actives. Dr. Gold disclosed that he is a consultant to and/or an investigator and a speaker for Joylux, InMode, and Alma Lasers.

In an editorial published in 2020, Dr. Alexiades reviewed the effects of fractional CO₂ laser treatment of vulvar skin on vaginal pH and referred to a study she conducted that found that the mean baseline pH pretreatment was 6.32 in the cohort of postmenopausal patients, and was reduced after 3 treatments. “Postmenopausally, the normal acidic pH becomes alkaline,” she said. But she did not expect to see an additional reduction in pH following the treatment out to 6 months. “This indicates that, whatever the wound healing and other restorative effects of these devices are, they seem to continue out to 6 months, at which point it turns around and moves toward baseline [levels].”

Dr. Alexiades highlighted two published meta-analyses of studies related to the genitourinary use of lasers and energy-based devices. One included 59 studies of 3,609 women treated for vaginal rejuvenation using either radiofrequency or fractional ablative laser therapy. The studies reported improvements in symptoms of GSM/VVA and sexual function, high patient satisfaction, with minor adverse events, including treatment-associated vaginal swelling or vaginal discharge.

“Further research needs to be completed to determine which specific pathologies can be treated, if maintenance treatment is necessary, and long-term safety concerns,” the authors concluded.

In another review, researchers analyzed 64 studies related to vaginal laser therapy for GSM. Of these, 47 were before and after studies without a control group, 10 were controlled intervention studies, and 7 were observational cohort and cross-sectional studies.

Vaginal laser treatment “seems to improve scores on the visual analogue scale, Female Sexual Function Index, and the Vaginal Health Index over the short term,” the authors wrote. “Safety outcomes are underreported and short term. Further well-designed clinical trials with sham-laser control groups and evaluating objective variables are needed to provide the best evidence on efficacy.”

“Lasers and energy-based devices are now considered alternative therapeutic modalities for genitourinary conditions,” Dr. Alexiades concluded. “The shortcomings in the literature with respect to lasers and device treatments demonstrate the need for the consensus on best practices and protocols.”

During a separate presentation at the meeting, Michael Gold, MD, highlighted data from Grand View Research, a market research database, which estimated that the global women’s health and wellness market is valued at more than $31 billion globally and is expected to grow at a compound annual growth rate of 4.8% from 2022 to 2030.

“Sales of women’s health energy-based devices continue to grow as new technologies are developed,” said Dr. Gold, a Nashville, Tenn.–based dermatologist and cosmetic surgeon who is also editor-in-chief of the Journal of Cosmetic Dermatology. “Evolving societal norms have made discussions about feminine health issues acceptable. Suffering in silence is no longer necessary or advocated.”

Dr. Alexiades disclosed that she has conducted research for Candela Lasers, Lumenis, Allergan/AbbVie, InMode, and Endymed. She is also the founder and CEO of Macrene Actives. Dr. Gold disclosed that he is a consultant to and/or an investigator and a speaker for Joylux, InMode, and Alma Lasers.
 

PHOENIX – While the use of lasers and energy-based devices for genitourinary indications dates back more than 50 years, a large body of scientific evidence has since accumulated for conditions ranging from genitourinary syndrome of menopause (GSM), lichen sclerosus, urinary incontinence, and vulvovaginal laxity.

“Even a cursory review of PubMed today yields over 100,000 results” on this topic, Macrene R. Alexiades, MD, PhD, associate clinical professor of dermatology at Yale University, New Haven, Conn., said at the annual conference of the American Society for Laser Medicine and Surgery. “Add to that radiofrequency and various diagnoses, the number of publications has skyrocketed, particularly over the last 10 years.”

What has been missing from this hot research topic all these years, she continued, is that no one has distilled this pile of data into a practical guide for office-based clinicians who use lasers and energy-based devices for genitourinary conditions – until now. Working with experts in gynecology and urogynecology, Dr. Alexiades spearheaded a 2-year-long effort to assemble a document on optimal protocols and best practices for genitourinary application of lasers and energy-based devices. The document, published soon after the ASLMS meeting in Lasers in Medicine and Surgery, includes a table that lists the current Food and Drug Administration approval status of devices in genitourinary applications, as well as individual sections dedicated to fractional lasers, radiofrequency (RF) devices, and high-intensity focused electromagnetic technology. It concludes with a section on the current status of clearances and future pathways.

“The work we did was exhaustive,” said Dr. Alexiades, who is also founder and director of Dermatology & Laser Surgery Center of New York. “We went through all the clinical trial data and compiled the parameters that, as a consensus, we agree are best practices for each technology for which we had rigorous published data.”

The document contains a brief background on the history of the devices used for genitourinary issues and it addresses core topics for each technology, such as conditions treated, contraindications, preoperative physical assessment and preparation, perioperative protocols, and postoperative care.

Contraindications to the genitourinary use of lasers and energy-based devices are numerous and include use of an intrauterine device, active urinary tract or genital infection, vaginal bleeding, current pregnancy, active or recent malignancy, having an electrical implant anywhere in the body, significant concurrent illness, and an anticoagulative or thromboembolic condition or taking anticoagulant medications 1 week prior to the procedure. Another condition to screen for is advanced prolapse, which was considered a contraindication in all clinical trials, she added. “It’s important that you’re able to do the speculum exam and stage the prolapse” so that a patient with this contraindication is not treated.

Dr. Alexiades shared the following highlights from the document’s section related to the use of fractional CO₂ lasers:

Preoperative management. Schedule the treatment one week after the patient’s menstrual period. Patients should avoid blood thinners for 7 days and avoid intercourse the night before the procedure. Reschedule in the case of fever, chills, or vaginal bleeding or discharge.

Preoperative physical exam and testing. A normal speculum exam and a recent negative PAP smear are required. For those of child-bearing potential, a pregnancy test is warranted. Obtain written and verbal consent, including discussion of all treatment options, risks, and benefits. No topical or local anesthesia is necessary internally. “Externally, we sometimes apply topical lidocaine gel, but I have found that’s not necessary in most cases,” Dr. Alexiades said. “The treatment is so quick.”

Peri-operative management. In general, device settings are provided by the manufacturer. “For most of the studies that had successful outcomes and no adverse events, researchers adhered to the mild or moderate settings on the technology,” she said. Energy settings were between 15 and 30 watts, delivered at a laser fluence of about 250-300 mJ/cm² with a spacing of microbeams 1 mm apart. Typically, three treatments are done at 1-month intervals and maintenance treatments are recommended at 6 and 12 months based on duration of the outcomes.

Vulvovaginal postoperative management. A 3-day recovery time is recommended with avoidance of intercourse during this period, because “re-epithelialization is usually complete in 3 days, so we want to give the opportunity for the lining to heal prior to introducing any friction, Dr. Alexiades said.” Rarely, spotting or discharge may occur and there should be no discomfort. “Any severe discomfort or burning may potentially signify infection and should prompt evaluation and possibly vaginal cultures. The patient can shower, but we recommend avoiding seated baths to decrease any introduction of infectious agents.”

Patients should be followed up monthly until three treatments are completed, and a maintenance treatment is considered appropriate between 6 and 12 months. “I do recommend doing a 1-month follow-up following the final treatment, unless it’s a patient who has already had a series of three treatments and is coming in for maintenance,” she said.

In a study from her own practice, Dr. Alexiades evaluated a series of three fractional CO₂ laser treatments to the vulva and vagina with a 1-year follow-up in postmenopausal patients. She used the Vaginal Health Index (VHI) to assess changes in vaginal elasticity, fluid volume, vaginal pH, epithelial integrity, and moisture. She and her colleagues discovered that there was improvement in every VHI category after treatment and during the follow-up interval up to 6 months.

“Between 6 and 12 months, we started to see a return a bit toward baseline on all of these parameters,” she said. “The serendipitous discovery that I made during the course of that study was that early intervention improves outcomes. I observed that the younger, most recently postmenopausal cohort seemed to attain normal or near normal VHI quicker than the more extended postmenopausal cohorts.”

Early menopause and delayed initiation of hormone therapy (HT) have been linked to an increase in Alzheimer’s disease (AD) pathology in women, a new imaging study shows.

Investigators found elevated levels of tau protein in the brains of women who initiated HT more than 5 years after menopause onset, while those who started the therapy earlier had normal levels.

Tau levels were also higher in women who started menopause before age 45, either naturally or following surgery, but only in those who already had high levels of beta-amyloid.

The findings were published online in JAMA Neurology.
 

Hotly debated

Previous research has suggested the timing of menopause and HT initiation may be associated with AD. However, the current research is the first to suggest tau deposition may explain that link.

“There have been a lot of conflicting findings around whether HT induces risk for Alzheimer’s disease dementia or not, and – at least in our hands – our observational evidence suggests that any risk is fairly limited to those rarer cases when women might delay their initiation of HT considerably,” senior investigator Rachel Buckley, PhD, assistant investigator in neurology at Massachusetts General Hospital and assistant professor of neurology at Harvard Medical School, Boston, told this news organization.

The link between HT, dementia, and cognitive decline has been hotly debated since the initial release of findings from the Women’s Health Initiative Memory Study, reported 20 years ago.

Since then, dozens of studies have yielded conflicting evidence about HT and AD risk, with some showing a protective effect and others showing the treatment may increase AD risk.

For this study, researchers analyzed data from 292 cognitively unimpaired participants (66.1% female) in the Wisconsin Registry for Alzheimer Prevention. About half of the women had received HT.

Women had higher levels of tau measured on PET imaging than age-matched males, even after adjustment for APOE status and other potential confounders.

Higher tau levels were found in those with an earlier age at menopause (P < .001) and HT use (P = .008) compared with male sex; later menopause onset; or HT nonuse – but only in patients who also had a higher beta-amyloid burden.

Late initiation of HT (> 5 years following age at menopause) was associated with higher tau compared with early initiation (P = .001), regardless of amyloid levels.
 

Surprising finding

Although researchers expected to find that surgical history (specifically oophorectomy) might have a greater impact on risk, that wasn’t the case.

“Given that bilateral oophorectomy involves the removal of both ovaries, and the immediate ceasing of estrogen production, I had expected this to be the primary driver of higher tau levels,” Dr. Buckley said. “But early age at menopause – regardless of whether the genesis was natural or surgical – seemed to have similar impacts.”

These findings are the latest from Dr. Buckley’s group that indicate that women tend to have higher levels of tau than men, regardless of preexisting amyloid burden in the brain.

“We see this in healthy older women, women with dementia, and even in postmortem cases,” Dr. Buckley said. “It really remains to be seen whether women tend to accumulate tau faster in the brain than men, or whether this is simply a one-shot phenomenon that we see in observational studies at the baseline.”

“One could really flip this finding on its head and suggest that women are truly resilient to the disease,” she continued. “That is, they can hold much more tau in their brain and remain well enough to be studied, unlike men.”

Among the study’s limitations is that the data were collected at a single time point and did not include information on subsequent Alzheimer’s diagnosis or cognitive decline.

“It is important to remember that the participants in this study were not as representative of the general population in the United States, so we cannot extrapolate our findings to women from a range of socioeconomic, racial and ethnic backgrounds or education levels,” she said.

The study’s observational design left researchers unable to demonstrate causation. What’s more, the findings don’t support the assertion that hormone therapy may protect against AD, Dr. Buckley added.

“I would more confidently say that evidence from our work, and that of many others, seems to suggest that HT initiated around the time of menopause may be benign – not providing benefit or risk, at least in the context of Alzheimer’s disease risk,” she said.

Another important takeaway from the study, Dr. Buckley said, is that not all women are at high risk for AD.

“Often the headlines might make you think that most women are destined to progress to dementia, but this simply is not the case,” Dr. Buckley said. “We are now starting to really drill down on what might elevate risk for AD in women and use this information to better inform clinical trials and doctors on how best to think about treating these higher-risk groups.”
 

New mechanism?

Commenting on the findings, Pauline Maki, PhD, professor of psychiatry, psychology and obstetrics & gynecology at the University of Illinois at Chicago, called the study “interesting.”

“It identifies a new mechanism in humans that could underlie a possible link between sex hormones and dementia,” Dr. Maki said.

However, Dr. Maki noted that the study wasn’t randomized and information about menopause onset was self-reported.

“We must remember that many of the hypotheses about hormone therapy and brain health that came from observational studies were not validated in randomized trials, including the hypothesis that hormone therapy prevents dementia,” she said.

The findings don’t resolve the debate over hormone therapy and AD risk and point to the need for randomized, prospective studies on the topic, Dr. Maki added. Still, she said, they underscore the gender disparity in AD risk.

“It’s a good reminder to clinicians that women have a higher lifetime risk of Alzheimer’s disease and should be advised on factors that might lower their risk,” she said.

The study was funded by the National Institutes of Health. Dr. Buckley reports no relevant financial conflicts. Dr. Maki serves on the advisory boards for Astellas, Bayer, Johnson & Johnson, consults for Pfizer and Mithra, and has equity in Estrigenix, Midi-Health, and Alloy.

Laser devices licensed in Canada to treat genitourinary syndrome of menopause (GSM) are often marketed for vaginal rejuvenation with claims that they will tighten the vagina and improve sexual function, despite lack of evidence, a new commentary reveals.

Vaginal lasers heat the vaginal epithelium and cause thermal necrosis. This intervention induces collagen remodeling and synthesis, neovascularization, and elastin formation and may result in improved vaginal elasticity and restoration of premenopausal epithelial function, according to coauthors Blayne Welk, MD, MSc, an associate professor of urologic surgery at Western University, London, Ont., and Erin Kelly, MD, a lecturer in obstetrics and gynecology at the University of Alberta, Edmonton.

Their patients’ questions and experiences with the laser devices prompted the commentary, they told this news organization.

“A large part of my practice involves addressing GSM and urinary incontinence,” said Dr. Kelly. “Many women present to the clinic having heard of vaginal laser procedures, having had vaginal laser procedures, or having been told they need vaginal laser procedures. My impression has been that these procedures are being marketed to women … without rigorous study.”

“Many women are reluctant to have mesh slings for stress incontinence due to some of the potential risks,” and they are looking for less invasive options, said Dr. Welk. Over the past few years, he has had increasing questions from patients about the use of lasers to improve this condition.

The commentary was published online in the Canadian Medical Association Journal.
 

Transparency needed

The first vaginal energy device was licensed by Health Canada in 2015 to treat GSM. That meant the device was deemed to have met basic safety, effectiveness, and quality criteria. But no controlled studies are required for regulatory approval of such devices, and after licensing, some providers rebranded the device indication from GSM to vaginal rejuvenation, said Dr. Kelly and Dr. Welk.

Vaginal laser therapies are offered throughout Canada, with at least one provider of vaginal rejuvenation procedures in the 10 most populous cities. Under the current system, the number of patients who pay for these procedures and the amount that they pay cannot be tracked. Nor can the number of vaginal laser systems active in Canada be tracked. Patients can refer themselves for the service, and providers’ publicly quoted costs (on websites, for example) are thousands of dollars for treatment.

The rebranding for vaginal rejuvenation “represents a difference between the licensing of a medical device by Health Canada and the way that these devices are used and marketed,” according to the commentary. “A procedure with limited high-quality evidence supporting its efficacy and a potential financial conflict of interest for providers may not be serving the best interests of people in Canada, even if the risk of adverse events is low.”

Updates to Canada’s medical devices action plan, including mandatory reporting of serious incidents and the ability to compel manufacturers to provide information on safety and effectiveness, “represent important progress,” according to Dr. Kelly and Dr. Welk. However, problems persist, including lack of a requirement for peer-reviewed, controlled studies.

Furthermore, women who undergo laser treatment for GSM, urinary incontinence, or vaginal rejuvenation may not receive a proper medical evaluation and standard treatments, the authors noted.

“I would like to see more transparency and public-facing information available on approved medical devices,” said Dr. Welk. “Health Canada has an online database of approved devices, but no information around the evidence submitted during the approval process is available, nor are the indications for the various devices.”

In addition, he said, many devices in the registry are listed by a serial number rather than the name that would be familiar to the public, “making it hard to match up information.”

Dr. Kelly added the “encouraging” news that the Canadian Society for Pelvic Medicine is working with Health Canada to “improve knowledge translation when it comes to transparency regarding medical devices.”
 

Medicine before marketing

“The commentary provides an accurate and evidence-based assessment of the use of vaginal laser treatments,” Jason Abbott, B Med (Hons), PhD, professor of gynecology at the University of New South Wales, Sydney, told this news organization. “The marketing of this device is a case of putting the cart before the horse. It is essential that strong, scientific, and reproducible studies be available on efficacy and safety before there is a direct-to-consumer marketing approach.” 

Clinicians should advise patients when the treatment effect is likely to be minimal or risky, especially when there is a financial incentive to the clinician, he said. “Governments, regulators, and medical societies have a duty of care to the public to make sure that the medicine comes before the marketing. Otherwise, we are no better than snake oil sellers.

“Given the size of studies to date, the improvement in symptoms following treatment may be less than a few percent,” he noted. “That may be acceptable to some women. We don’t know.” 

Dr. Abbott’s team is conducting research to define what women would want as a minimal level of improvement, the maximum cost, and the maximum risk from the laser procedure.  

“In cancer … the benefit of a new treatment may only be a few percent for survival,” he said. “That may be completely acceptable for some or even many patients. What we cannot do, however, is extrapolate those same expectations to a treatment for a benign condition where quality of life is compromised.”  

Echoing Dr. Kelly and Dr. Welk, Dr. Abbott said, “It is important that there be transparency in the clinical communication. Patients should be told that the best scientific studies that are judged based on their quality show there is no benefit to laser treatment for GSM or urinary incontinence.” 

Although the medical risks may be low, he added, “financial risk also needs to be discussed. Patients should be encouraged to participate in clinical trials where there is no cost to them to gain the information first, before wholesale uptake of the treatment. … Should patients still wish to undergo the procedure once the risks and an honest account of the evidence is given to them, that of course is their choice.” Dr. Kelly, Dr. Welk, and Dr. Abbott had no commercial funding or relevant financial relationships to report.

Laser devices licensed in Canada to treat genitourinary syndrome of menopause (GSM) are often marketed for vaginal rejuvenation with claims that they will tighten the vagina and improve sexual function, despite lack of evidence, a new commentary reveals.

Vaginal lasers heat the vaginal epithelium and cause thermal necrosis. This intervention induces collagen remodeling and synthesis, neovascularization, and elastin formation and may result in improved vaginal elasticity and restoration of premenopausal epithelial function, according to coauthors Blayne Welk, MD, MSc, an associate professor of urologic surgery at Western University, London, Ont., and Erin Kelly, MD, a lecturer in obstetrics and gynecology at the University of Alberta, Edmonton.

Their patients’ questions and experiences with the laser devices prompted the commentary, they told this news organization.

“A large part of my practice involves addressing GSM and urinary incontinence,” said Dr. Kelly. “Many women present to the clinic having heard of vaginal laser procedures, having had vaginal laser procedures, or having been told they need vaginal laser procedures. My impression has been that these procedures are being marketed to women … without rigorous study.”

“Many women are reluctant to have mesh slings for stress incontinence due to some of the potential risks,” and they are looking for less invasive options, said Dr. Welk. Over the past few years, he has had increasing questions from patients about the use of lasers to improve this condition.

The commentary was published online in the Canadian Medical Association Journal.
 

Transparency needed

The first vaginal energy device was licensed by Health Canada in 2015 to treat GSM. That meant the device was deemed to have met basic safety, effectiveness, and quality criteria. But no controlled studies are required for regulatory approval of such devices, and after licensing, some providers rebranded the device indication from GSM to vaginal rejuvenation, said Dr. Kelly and Dr. Welk.

Vaginal laser therapies are offered throughout Canada, with at least one provider of vaginal rejuvenation procedures in the 10 most populous cities. Under the current system, the number of patients who pay for these procedures and the amount that they pay cannot be tracked. Nor can the number of vaginal laser systems active in Canada be tracked. Patients can refer themselves for the service, and providers’ publicly quoted costs (on websites, for example) are thousands of dollars for treatment.

The rebranding for vaginal rejuvenation “represents a difference between the licensing of a medical device by Health Canada and the way that these devices are used and marketed,” according to the commentary. “A procedure with limited high-quality evidence supporting its efficacy and a potential financial conflict of interest for providers may not be serving the best interests of people in Canada, even if the risk of adverse events is low.”

Updates to Canada’s medical devices action plan, including mandatory reporting of serious incidents and the ability to compel manufacturers to provide information on safety and effectiveness, “represent important progress,” according to Dr. Kelly and Dr. Welk. However, problems persist, including lack of a requirement for peer-reviewed, controlled studies.

Furthermore, women who undergo laser treatment for GSM, urinary incontinence, or vaginal rejuvenation may not receive a proper medical evaluation and standard treatments, the authors noted.

“I would like to see more transparency and public-facing information available on approved medical devices,” said Dr. Welk. “Health Canada has an online database of approved devices, but no information around the evidence submitted during the approval process is available, nor are the indications for the various devices.”

In addition, he said, many devices in the registry are listed by a serial number rather than the name that would be familiar to the public, “making it hard to match up information.”

Dr. Kelly added the “encouraging” news that the Canadian Society for Pelvic Medicine is working with Health Canada to “improve knowledge translation when it comes to transparency regarding medical devices.”
 

Medicine before marketing

“The commentary provides an accurate and evidence-based assessment of the use of vaginal laser treatments,” Jason Abbott, B Med (Hons), PhD, professor of gynecology at the University of New South Wales, Sydney, told this news organization. “The marketing of this device is a case of putting the cart before the horse. It is essential that strong, scientific, and reproducible studies be available on efficacy and safety before there is a direct-to-consumer marketing approach.” 

Clinicians should advise patients when the treatment effect is likely to be minimal or risky, especially when there is a financial incentive to the clinician, he said. “Governments, regulators, and medical societies have a duty of care to the public to make sure that the medicine comes before the marketing. Otherwise, we are no better than snake oil sellers.

“Given the size of studies to date, the improvement in symptoms following treatment may be less than a few percent,” he noted. “That may be acceptable to some women. We don’t know.” 

Dr. Abbott’s team is conducting research to define what women would want as a minimal level of improvement, the maximum cost, and the maximum risk from the laser procedure.  

“In cancer … the benefit of a new treatment may only be a few percent for survival,” he said. “That may be completely acceptable for some or even many patients. What we cannot do, however, is extrapolate those same expectations to a treatment for a benign condition where quality of life is compromised.”

The selective estrogen receptor modulator ospemifene appears to improve the vaginal microbiome of postmenopausal women with vulvovaginal atrophy (VVA), according to results from a small Italian case-control study in the journal Menopause.

The study sheds microbiological light on the mechanisms of ospemifene and low-dose systemic hormone therapy, which are widely used to treat genitourinary symptoms. Both had a positive effect on vaginal well-being, likely by reducing potentially harmful bacteria and increasing health-promoting acid-friendly microorganisms, writes a group led by M. Cristina Meriggiola, MD, PhD, of the gynecology and physiopathology of human reproduction unit at the University of Bologna, Italy.

VVA occurs in about 50% of postmenopausal women and produces a less favorable, less acidic vaginal microbiome profile than that of unaffected women. “The loss of estrogen leads to lower concentrations of Lactobacilli, bacteria that lower the pH. As a result, other bacterial species fill in the void,” explained Stephanie S. Faubion, MD, MBA, director of the Mayo Clinic Center for Women’s Health in Jacksonville, Fla., and medical director of the North American Menopause Society.

Added Tina Murphy, APN, a NAMS-certified menopause practitioner at Northwestern Medicine Orland Park in Illinois, “When this protective flora declines, then pathogenic bacteria can predominate the microbiome, which can contribute to vaginal irritation, infection, UTI’s, dyspareunia, and discomfort. Balancing and restoring the microbiome can mitigate the effects of estrogen depletion on the vaginal tissue and prevent the untoward effects of the hypoestrogenic state.” While ospemifene and hormone therapy are common therapies for the genitourinary symptoms of menopause, the focus has been on their treatment efficacy, not their effect on the microbiome profile, added Dr. Faubion. Only about 9% of women with menopause-related genitourinary symptoms receive prescription treatment, she added.
 

The study

Of 67 eligible postmenopausal participants in their mid-50s enrolled at a gynecology clinic from April 2019 to February 2020, 39 were diagnosed with VVA and 28 were considered healthy controls. In the atrophic group, 20 were prescribed ospemifene and 19 received hormone treatment.

Only those women with VVA but no menopausal vasomotor symptoms received ospemifene (60 mg/day); symptomatic women received hormone therapy according to guidelines.

The researchers calculated the women’s vaginal health index (VHI) based on elasticity, secretions, pH level, epithelial mucosa, and hydration. They used swabs to assess vaginal maturation index (VMI) by percentages of superficial, intermediate, and parabasal cells. Evaluation of the vaginal microbiome was done with 16S rRNA gene sequencing, and clinical and microbiological analyses were repeated after 3 months.

The vaginal microbiome of atrophic women was characterized by a significant reduction of benign Lactobacillus bacteria (P = .002) and an increase of potentially pathogenic Streptococcus (P = .008) and Sneathia (P = .02) bacteria.

The vaginal microbiome of women with VVA was depleted, within the Lactobacillus genus, in the L. crispatus species, a hallmark of vaginal health that has significant antimicrobial activity against endogenous and exogenous pathogens.

Furthermore, there was a positive correlation between the VHI/VMI and Lactobacillus abundance (P = .002 and P = 0.035, respectively).

While the lactic acid–producing Lactobacillus and Bifidobacterium genera were strongly associated with healthy controls, the characteristics of VVA patients were strongly associated with Streptococcus, Prevotella, Alloscardovia, and Staphylococcus.

Both therapeutic approaches effectively improved vaginal indices but by different routes. Systemic hormone treatment induced changes in minority bacterial groups in the vaginal microbiome, whereas ospemifene eliminated specific harmful bacterial taxa, such as Staphylococcus (P = .04) and Clostridium (P = .01). Both treatments induced a trend in the increase of beneficial Bifidobacteria.

A 2022 study reported that vaginal estradiol tablets significantly changed the vaginal microbiota in postmenopausal women compared with vaginal moisturizer or placebo, but the reductions in bothersome symptoms were similar.
 

The future

“Areas for future study include the assessment of changes in the vaginal microbiome, proteomic profiles, and immunologic markers with various treatments and the associations between these changes and genitourinary symptoms,” Dr. Faubion said. She added that, while there may be a role at some point for oral or topical probiotics, “Thus far, probiotics have not demonstrated significant benefits.”

Meanwhile, said Ms. Murphy, “There are many options available that may benefit our patients. As a provider, meeting with your patient, discussing her concerns and individual risk factors is the most important part of choosing the correct treatment plan.”

The authors call for further studies to confirm the observed modifications of the vaginal ecosystem. In the meantime, Dr. Meriggiola said in an interview, “My best advice to physicians is to ask women if they have this problem. Do not ignore it; be proactive and treat. There are many options on the market for genitourinary symptoms – not just for postmenopausal women but breast cancer survivors as well.”

Dr. Meriggiola’s group is planning to study ospemifene in cancer patients, whose quality of life is severely affected by VVA.

This study received no financial support. Dr. Meriggiola reported past financial relationships with Shionogi Limited, Teramex, Organon, Italfarmaco, MDS Italia, and Bayer. Coauthor Dr. Baldassarre disclosed past financial relationships with Shionogi. Ms. Murphy disclosed no relevant conflicts of interest with respect to her comments. Dr. Faubion is medical director of the North American Menopause Society and editor of the journal Menopause.

Hormone replacement therapy (HRT) introduced early during the menopausal transition may protect against Alzheimer’s dementia in women carrying the APOE4 gene, new research suggests.

Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.

HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.

“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.

“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.

The findings were published online in Alzheimer’s Research and Therapy.
 

Personalized approaches

Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.

“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.

HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”

The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”

This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.

To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.

Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.

The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.

The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.

Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
 

‘Critical window’

The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).

Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).

“This large effect was found only in APOE4 carriers,” the investigators noted.

Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).

In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).

In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.

Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.

“The key important point here is the timing, or the ‘critical window,’ when HRT can be of most benefit,” Dr. Saleh said. “This is most beneficial when introduced early, before the neuropathology becomes irreversible.”

Study limitations include its cross-sectional design, which precludes the establishment of a causal relationship, and the fact that information regarding the type and dose of estrogen was not available for all participants.

HRT is not without risk, Dr. Saleh noted. She recommended that clinicians “carry out various screening tests to make sure that a woman is eligible for HRT and not at risk of hypercoagulability, for instance.”
 

Risk-benefit ratio

In a comment, Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, called the study “exactly the kind of work that needs to be done.”

Dr. Fillit, who was not involved with the current research, is a clinical professor of geriatric medicine, palliative care medicine, and neuroscience at Mount Sinai Hospital, New York.

He compared the process with that of osteoporosis. “We know that if women are treated [with HRT] at the time of the menopause, you can prevent the rapid bone loss that occurs with rapid estrogen loss. But if you wait 5, 10 years out, once the bone loss has occurred, the HRT doesn’t really have any impact on osteoporosis risk because the horse is already out of the barn,” he said.

Although HRT carries risks, “they can clearly be managed; and if it’s proven that estrogen or hormone replacement around the time of the menopause can be protective [against AD], the risk-benefit ratio of HRT could be in favor of treatment,” Dr. Fillit added.

The study was conducted as part of the Medical Research Council NuBrain Consortium. The investigators and Dr. Fillit reported no relevant financial relationships.

Hormone replacement therapy (HRT) introduced early during the menopausal transition may protect against Alzheimer’s dementia in women carrying the APOE4 gene, new research suggests.

Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.

HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.

“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.

“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.

The findings were published online in Alzheimer’s Research and Therapy.
 

Personalized approaches

Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.

“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.

HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”

The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”

This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.

To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.

Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.

The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.

The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.

Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
 

‘Critical window’

The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).

Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).

“This large effect was found only in APOE4 carriers,” the investigators noted.

Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).

In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).

In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.

Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.

“The key important point here is the timing, or the ‘critical window,’ when HRT can be of most benefit,” Dr. Saleh said. “This is most beneficial when introduced early, before the neuropathology becomes irreversible.”

Study limitations include its cross-sectional design, which precludes the establishment of a causal relationship, and the fact that information regarding the type and dose of estrogen was not available for all participants.

HRT is not without risk, Dr. Saleh noted. She recommended that clinicians “carry out various screening tests to make sure that a woman is eligible for HRT and not at risk of hypercoagulability, for instance.”

The standard nonsurgical treatment for pelvic organ prolapse does not appear to work as well as surgery to correct the problem, Dutch researchers have found. 

Pelvic organ prolapse is an uncomfortable condition, causing a troublesome vaginal bulge, often accompanied by urinary, bowel, or sexual dysfunction. Between 3% and 6% of women develop symptomatic prolapse, with the highest incidence in women aged 60-69 years – a fast-growing demographic.

Although many women choose surgical treatment, the American College of Obstetricians and Gynecologists recommends that women be offered a vaginal pessary as a noninvasive alternative, despite inconsistent data from observational studies on their effectiveness.

Lisa van der Vaart, MD, a doctoral student in ob.gyn. at the University of Amsterdam and the lead author of the new study, published in JAMA, said that differences in outcome measures, small sample size, and lack of long-term follow-up have bedeviled previous comparisons of the two techniques.

“We thought it was very important to perform a randomized control trial on this subject to improve counseling to women who suffer from symptomatic pelvic organ prolapse,” Dr. van der Vaart said.

She and her colleagues conducted a noninferiority randomized clinical trial that recruited 1,605 women with stage II or higher prolapse who were referred to specialty care at 21 hospitals in the Netherlands between 2015 and 2019. Of the 440 women who agreed to participate in the trial, 218 received a pessary, a device inserted into the vagina that provides support to tissues displaced by prolapse, and 222 underwent surgery.

The primary outcome was subjective improvement using a standardized questionnaire at 24 months; women were asked to rank their symptoms on a seven-point scale, and subjective improvement was defined as a response of much better or very much better.

“We saw a substantial amount of improvement in both groups,” Dr. van der Vaart said in an interview.

After 24 months of follow-up, outcome data were available for 173 women in the pessary group and 162 in the surgery group. For this intention-to treat population, 76.3% in the pessary group and 81.5% in the surgery group reported improvement.

Results were similar for the smaller group of participants who completed the study per protocol, without crossing over to a treatment to which they had not been allocated.

However, neither the intention-to-treat nor per-protocol analysis met the prespecified criteria for noninferiority, suggesting that use of a vaginal pessary is not equivalent to surgery.

The study also found differences in adverse events. Among women randomly assigned to surgery, 9% suffered a postoperative urinary tract infection, and 5.4% underwent additional therapy, such as pessary or repeat operation.

But use of a pessary also had downsides. The most common adverse event was discomfort (42.7%), and by 24 months, 60% of the participants in the pessary group had discontinued use.

Dr. van der Vaart said that she was surprised by the high number of women assigned to the pessary group who later elected to undergo surgery. “Women should be told that their chance of crossing over to a surgical intervention is quite high – more than 50% do eventually end up having surgery.”

Cheryl Iglesia, MD, director of the National Center for Advanced Pelvic Surgery at MedStar Health and professor of obstetrics and gynecology and urology at Georgetown University, both in Washington, was also struck by the high crossover rate. “We’ve had the same pessaries probably for the last 100 years,” she said. “We need to get better.”

Dr. Iglesia welcomed new approaches to making vaginal pessaries that are custom designed for each woman’s unique anatomy using 3D printing and pointed to promising initial clinical trials of disposable pessaries. With the aging of the population and demand for treatment of prolapse increasing, she cited a need for better nonsurgical alternatives: “We have a work-force issue and may not have enough adequately trained urogynecologists to meet the demand for prolapse repairs as our population ages.”

The study was funded by a grant from ZonMW, a Dutch governmental health care organization. Dr. van der Vaart reported grants from ZonMW during the conduct of the study.

OBG Management caught up with Drs. Jan Shifren and Genevieve Neal-Perry while they were attending the annual meeting of The North American Menopause Society (NAMS), held October 12-15, 2022, in Atlanta, Georgia. Dr. Shifren presented on the “Ins and Outs of Hormone Therapy,” while Dr. Neal-Perry focused on “Menopause Physiology.” 

Evaluating symptomatic patients for appropriate hormone therapy

OBG Management: In your presentation to the group at the NAMS meeting, you described a 51-year-old patient with the principal symptoms of frequent hot flashes and night sweats, sleep disruption, fatigue, irritability, vaginal dryness, and dyspareunia. As she reported already trying several lifestyle modification approaches, what are your questions for her to determine whether hormone therapy (HT), systemic or low-dose vaginal, is advisable?

Jan Shifren, MD: As with every patient, you need to begin with a thorough history and confirm her physical exam is up to date. If there are concerns related to genitourinary symptoms of menopause (GSM), then a pelvic exam is indicated. This patient is a healthy menopausal woman with bothersome hot flashes, night sweats, and vaginal dryness. Sleep disruption from night sweats is likely the cause of her fatigue and irritability, and her dyspareunia due to atrophic vulvovaginal changes. The principal indication for systemic HT is bothersome vasomotor symptoms (VMS), and a healthy woman who is under age 60 or within 10 years of the onset of menopause is generally a very good candidate for hormones. For this healthy 51-year-old with bothersome VMS unresponsive to lifestyle modification, the benefits of HT should outweigh potential risks. As low-dose vaginal estrogen therapy is minimally absorbed and very safe, this would be recommended instead of systemic HT if her only menopause symptoms were vaginal dryness and dyspareunia.

HT types and formulations

OBG Management: For this patient, low-dose vaginal estrogen is appropriate. In general, how do you decide on recommendations for combination therapy or estrogen only, and what formulations and dosages do you recommend?

Dr. Shifren: Any woman with a uterus needs to take a progestogen together with estrogen to protect her uterus from estrogen-induced endometrial overgrowth. With low dose vaginal estrogen therapy, however, concurrent progestogen is not needed.

Continue to: Estrogen options...

Many of our patients like the idea that they are using “natural” HT. I inform them that bioidentical is a marketing term rather than a medical term, but if their goal is to take the same hormones that their ovaries made when they were younger, they should use FDA-approved formulations of estradiol and progesterone for their menopausal HT symptoms. I do not recommend compounded bioidentical HT due to concerns regarding product quality and safety. The combination of FDA-approved estradiol patches and oral micronized progesterone provides a high quality, carefully regulated bioidentical HT regimen. For women greatly preferring an oral estrogen, oral estradiol with micronized progesterone is an option.

In addition to patient preference for natural HT, the reasons that I encourage women to consider the estradiol transdermal patch for their menopausal HT include:

1. no increased risk of venous thromboembolic events when physiologically dosed menopausal estradiol therapy is provided by a skin patch (observational data).¹ With oral estrogens, even when dosed for menopause, VTE risk increases, as coagulation factors increase due to the first-pass hepatic effect. This does not occur with non-oral menopausal estrogens.
2. no increased risk of gallbladder disease, which occurs with oral estrogen therapy (observational data)²
3. possibly lower risk of stroke when low-dose menopausal HT is provided via skin patch (observational data)³
4. convenience—the patches are changed once or twice weekly
5. wide range of doses available, which optimizes identifying the lowest effective dose and decreasing the dose over time.

Progestogen options. Progestogens may be given daily or cyclically. Use of daily progestogen typically results in amenorrhea, which is preferred by most women. Cyclic use of a progestogen for 12-14 days each month results in a monthly withdrawal bleed, which is a good option for a woman experiencing bothersome breakthrough bleeding with daily progestogen. Use of a progestogen-releasing IUD is an off-label alternative for endometrial protection with menopausal HT. As discussed earlier, as many women prefer bioidentical HT, one of our preferred regimens is to provide transdermal estradiol with FDA-approved oral micronized progesterone. There are several patches that combine estradiol with a progestogen, but there is not a lot of dosing flexibility and product choice. There also is an approved product available that combines oral estradiol and micronized progesterone in one tablet.

Scheduling follow-up

OBG Management: Now that you have started the opening case patient on HT, how often are you going to monitor her for treatment?

Dr. Shifren: Women will not experience maximum efficacy for hot flash relief from their estrogen therapy for 3 months, so I typically see a patient back at 3 to 4 months to assess side effects and symptom control. I encourage women to reach out sooner if they are having a bothersome side effect. Once she is doing well on an HT regimen, we assess risks and benefits of ongoing treatment annually. The goal is to be certain she is on the lowest dose of estrogen that treats her symptoms, and we slowly decrease the estrogen dose over time.

Breast cancer risk

OBG Management: In your presentation, you mentioned that the risk of breast cancer does not increase appreciably with short-term use of HT. Is it possible to define short term?

Dr. Shifren: In the Women’s Health Initiative (WHI), a large double-blind, randomized, placebo-controlled trial of menopausal HT, there was a slight increase in breast cancer risk after approximately 4 to 5 years of use in women using estrogen with progestogen.⁴ I share with patients that this increased risk is about the same as that of obesity or drinking more than 1 alcoholic beverage daily. As an increased risk of breast cancer does not occur for several years, a woman may be able to take hormones for bothersome symptoms, feel well, and slowly come off without incurring significant breast cancer risk. In the WHI, there was no increase in breast cancer risk in women without a uterus randomized to estrogen alone.

Regarding cardiovascular risk, in the WHI, an increased risk of cardiovascular events generally was not seen in healthy women younger than age 60 and within 10 years of the onset of menopause.⁵ Benefits of HT may not outweigh risks for women with significant underlying cardiovascular risk factors, even if they are younger and close to menopause onset.

Continue to: The importance of shared decision making...

Dr. Shifren: As with any important health care decision, women should be involved in an individualized discussion of risks and benefits, with shared decision making about whether HT is the right choice. Women also should be involved in ongoing decisions regarding HT formulation, dose, and duration of use.

A nonhormonal option for hot flashes

OBG Management: How many women experience VMS around the time of menopause?

Dr. Genevieve Neal-Perry, MD, PhD: About 60% to 70% of individuals will experience hot flashes around the time of the menopause.⁶ Of those, about 40% are what we would call moderate to severe hot flashes—which are typically the most disruptive in terms of quality of life.⁷ The window of time in which they are likely to have them, at typically their most intense timeframe, is 2 years before the final menstrual period and the year after.⁷ In terms of the average duration, however, it’s about 7 years, which is a lot longer than what we previously thought.⁸ Moreover, there are disparities in that women of color, particularly African American women, can have them as long as 10 years.⁸
 

OBG Management: Can you explain why the VMS occur, and specifically around the time of menopause?

Dr. Neal-Perry: For many years we did not understand the basic biology of hot flashes. When you think about it, it’s completely amazing—when half of our population experiences hot flashes, and we don’t understand why, and we don’t have therapy that specifically targets hot flashes.

What we now know from work completed by Naomi Rance, in particular, is that a specific region of the brain, the hypothalamus, exhibited changes in number of neurons that seemed to be increased in size in menopausal people and smaller in size in people who were not menopausal.⁹ That started the journey to understanding the biology, and eventual mechanism, of hot flashes. It took about 10-15 years before we really began to understand why.

What we know now is that estrogen, a hormone that is made by the ovaries, activates and inactivates neurons located in the hypothalamus, a brain region that controls our thermoregulation—the way your body perceives temperature. The hypothalamus controls your response to temperature, either you experience chills or you dissipate heat by vasodilating (hot flush) and sweating.

The thermoregulatory region of the hypothalamus houses cells that receive messages from KNDy neurons, neurons also located in the hypothalamus that express kisspeptin, neurokinin, and dynorphin. Importantly, KNDy neurons express estrogen receptors. (The way that I like to think about estrogen and estrogen receptors is that estrogen is like the ball and the receptor is like the catcher’s mitt.) When estrogen interacts with this receptor, it keeps KNDy neurons quiet. But the increased variability and loss of estrogen that occurs around the time of menopause “disinhibits” KNDy neurons—meaning that they are no longer being reined in by estrogen. In response to decreased estrogen regulation, KNDy neurons become hypertrophied with neurotransmitters and more active. Specifically, KNDy neurons release neurokinin, a neuropeptide that self-stimulates KNDy neurons and activates neurons in the thermoregulatory zone of the brain—it’s a speed-forward feed-backward mechanism. The thermoregulatory neurons interpret this signal as “I feel hot,” and the body begins a series of functions to cool things down.

Dr. Neal-Perry: I have described what happens in the brain around the time of menopause, and what triggers those hot flashes.

Estrogen. The reason that estrogen worked to treat the hot flashes is because estrogen inhibits and calms the neurons that become hyperactive during the menopause.

Fezolinetant. Fezolinetant is unique because it specifically targets the hormone receptor that triggers hot flashes, the neurokinin receptor. Fezolinetant is a nonhormone therapy that not only reduces the activity of KNDy neurons but also blocks the effects of neurons in the thermoregulatory zone, thereby reducing the sensation of the hot flashes. We are in such a special time in medical history for individuals who experience hot flashes because now we understand the basic biology of hot flashes, and we can generate targeted therapy to manage hot flashes—that is for both individuals who identify as women and individuals who identify as men, because both experience hot flashes.
 

OBG Management: Is there a particular threshold of hot flash symptoms that is considered important to treat, or is treatment based on essentially the bother to patients?

Dr. Neal-Perry: Treatment is solely based on if it bothers the patient. But we do know that people who have lots of bothersome hot flashes have a higher risk for heart disease and may have sleep disruption, reduced cognitive function, and poorer quality of life. Sleep dysfunction can impact the ability to think and function and can put those affected at increased risk for accidents.

For people who are having these symptoms that are disruptive to their life, you do want to treat them. You might say, “Well, we’ve had estrogen, why not use estrogen,” right? Well estrogen works very well, but there are lots of people who can’t use estrogen—individuals who have breast cancer, blood clotting disorders, significant heart disease, or diabetes. Then there are just some people who don’t feel comfortable using estrogen.

We have had a huge gap in care for individuals who experience hot flashes and who are ineligible for menopausal HT. While there are other nonhormonal options, they often have side effects like sexual dysfunction, hypersomnolence, or insomnia. Some people choose not to use these nonhormonal treatments because the side effects are worse for them than to trying to manage the hot flashes. The introduction to a nonhormonal therapy that is effective and does not have lots of side effects is exciting and will be welcomed by many who have not found relief.
 

OBG Management: Is fezolinetant available now for patients?

Dr. Neal-Perry: It is not available yet. Hopefully, it will be approved within the next year. Astellas recently completed a double blind randomized cross over design phase 3 study that found fezolinetant is highly effective for the management of hot flashes and that it has a low side effect profile.¹⁰ Fezolinetant’s most common side effect was COVID-19, a reflection of the fact that the trial was done during the COVID pandemic. The other most common side effect was headache. Everything else was minimal.

Other drugs in the same class as fezolinetant have been under development for the management of hot flashes; however, they encountered liver function challenges, and studies were stopped. Fezolinetant did not cause liver dysfunction.

Hot flash modifiers

OBG Management: Referring to that neuropathway, are there physiologic differences among women who do and do not experience hot flashes, and are there particular mechanisms that may protect patients against being bothered by hot flashes?

Dr. Neal-Perry: Well, there are some things that we can control, and there are things that we cannot control (like our genetic background). Some of the processes that are important for estrogen receptor function and estrogen metabolism, as well as some other receptor systems, can work differently. When estrogen metabolism is slightly different, it could result in reduced estrogen receptor activity and more hot flashes. Then there are some receptor polymorphisms that can increase or reduce the risk for hot flashes—the genetic piece.¹¹

There are things that can modify your risk for hot flashes and the duration of hot flashes. Individuals who are obese or smoke may experience more hot flashes. Women of color, especially African American women, tend to have hot flashes occur earlier in their reproductive life and last for a longer duration; hot flashes may occur up to 2 years before menopause, last for more than 10 years, and be more disruptive. By contrast, Asian women tend to report fewer and less disruptive hot flashes.⁸
 

OBG Management: If fezolinetant were to be FDA approved, will there be particular patients that it will most appropriate for, since it is an estrogen alternative?

Dr. Neal-Perry: Yes, there may be different patients who might benefit from fezolinetant. This will depend on what the situation is—patients who have breast cancer, poorly controlled diabetes, or heart disease, and those patients who prefer not to use estrogen will benefit from fezolinetant, as we are going to look for other treatment options for those individuals. It will be important for medical providers to listen to their patients and understand the medical background of that individual to really define what is the best next step for the management of their hot flashes.

This is an exciting time for individuals affected by menopausal hot flashes; to understand the biology of hot flashes gives us real opportunities to bridge gaps around how to manage them. Individuals who experience hot flashes will know that they don’t have to suffer, that there are other options that are safe, that can help meet their needs and put them in a better place. ●

Multiethnic differences in the menopause experience

---

Excerpted from the presentation, “Do you see me? Culturally responsive care in menopause,” by Makeba Williams, MD, NCMP, at The North American Menopause Society meeting in Atlanta, Georgia, October 12-15, 2022.

Dr. Williams is Vice Chair of Professional Development and Wellness, Associate Professor, Washington University School of Medicine

The Study of Women’s Health Across the Nation (SWAN) challenged the notion that there is a universal menopausal experience.¹ Up until that time, we had been using this universal experience that is based largely on the experiences of White women and applying that data to the experiences of women of color. Other research has shown that African American women have poorer quality of life and health status, and that they receive less treatment for a number of conditions.^2,3

In a recent review of more than 20 years of literature, we found only 17 articles that met the inclusion criteria, reflecting the invisibility of African American women and other ethnic and racial minorities in the menopause literature and research. Key findings included that African American women^1,4:

• experience an earlier age of onset of menopause
• have higher rates of premature menopause and early menopause, which is a risk factor for cardiovascular disease
• experience a longer time of the menopausal transition, with variability in the average age of menopause onset
• overall report lower rates of vaginal symptoms
• are less likely to report sleep disturbances than White women or Hispanic women, but more likely to report these symptoms than Asian women
• experience a higher prevalence, frequency, and severity of vasomotor symptoms (VMS), and were more bothered by those symptoms

− 48.4 years in the Healthy Women’s Study

− 50.9 years in the Penn Ovarian Aging Study

− 51.4 years in SWAN

• reported lower educational attainment, experiencing more socioeconomic disadvantage and exposure to more adverse life effects
• receive less treatment for VMS, hypertension, and depression, and are less likely to be prescribed statin drugs
• experience more discrimination
• use cigarettes and tobacco more, but are less likely to use alcohol and less likely to have physical activity.

Cultural influences on menopause

Im and colleagues have published many studies looking at cultural influences on African American, Hispanic, and Asian American women, and comparing them to White women.⁵ Notable differences were found regarding education level, family income, employment, number of children, and greater perceived health (which is associated with fewer menopausal symptoms). They identified 5 qualitative ideas:

1. Positive acceptance. Minority women, or racial and ethnic women, perceived the transition to menopause more positively, and generally took on a posture of acceptance, reporting feeling liberated from many of the challenges associated with the reproductive period. In addition, many associated a greater sense of maturity and respect within their communities with the natural aging process.
2. Optimism. Ethnic women tended to embrace menopause, using humor and laughter to express emotions during stressful life changes. This runs counter to many of the perspectives reported by White women, who often viewed the menopausal transition and aging negatively, as we equate aging with the loss of youthfulness in the United States.
3. Unique, not universal. Most of the ethnic minority women thought that there was something unique about their menopausal experiences, and that they were influenced by immigration transition, financial situations, etc. Many White woman perceived that the menopausal experience was shared among all women.
4. Closed, not open. There were differences in how we talk about symptoms, or whether or not we talk about them at all. Ethnic women tended to be silent about their symptoms. By contrast, White women tended to be more open and talkative and communicative about their symptoms.
5. Minimizing, not controlling. No symptom management was the strategy of choice for most women. Minority women tended to manage their symptoms by tolerating and normalizing them. Only those women with the most serious symptoms sought out medication for temporary relief. Some expressed a tendency to downplay their symptoms because many of them had more important things that they were dealing with in their lives.

What is an individual social identity?

An individual social identity reflects the many groups to which one belongs. It is how one shows up, and yet it is much more than how they physically show up. When you pass your eye on patients, you are only seeing the tip of the iceberg. The full social identity of a patient resides below the surface. Social identity is complex, on a continuum, and can change depending on time and place. How we prioritize our social identities may change, depending on the context and the situation.

Our intersecting social identities give rise to our cultural identity, and it is through the prism of intersectionality that we can understand the ways in which our social identities converge to give rise to disparities in health care in midlife and menopausal women. Holding space for cultural identity, we can impact how our patients are perceiving their menopause, how they are moving through decision making about taking care of themselves in menopause. And we can provide more responsive care to their cultural identities, and hopefully at the end of the day we reduce some of these disparities that we are seeing in our menopausal patients and also are reducing our unconscious bias in our patient interactions.

Culturally responsive care

There are several components to home in on when we are trying to provide culturally responsive care to patients.

1. A commitment to being culturally curious. We have to accept what the literature is sharing with us, that there is not a universal menopausal experience. We have for far too long applied this universal experience of menopause that has largely been based on White women to different racial and ethnic populations.
2. Recognizing. I appreciate that my identity as a Black woman may be very different from other Black women in the room, or whatever their social identity. I am not expected to understand all of the others’ experiences, and I don’t expect that for you either.
3. Acknowledge unconscious implicit biases. Acknowledge the groups to which you have a strong implicit bias, and allow it to drive you to reduce barriers to engaging with patients.
4. Connecting with the individual patient. It is through a process of individuating that we learn from our patients’ unique characteristics, rather than relying on assumptions and stereotypes. We have a window of opportunity to see our patient and move beyond thinking of them in terms of racial and ethnic stereotypes or particular social groups. It is through this process of individualizing that we can seek answers to key questions.

The ultimate goal is to understand our individual patients’ perceptions, outlook on menopause, and contextual factors in their lives that influence the menopause journey.

CASE ENCOUNTER

I quickly look at the patient-filled form before I knock on the exam door, and I see that the patient has checked off that she has hot flashes, night sweats, and I make a mental note, she’s menopausal. I already have a preliminary plan to give this patient hormone therapy. I open the door, and I see that she’s Black. I know, based upon the data from SWAN and others, that her menopause means longer duration, more severe vasomotor symptoms. I have already teed up a prescription to go to the pharmacy.

The problem is, I have not even talked to her. She may actually nod her head, saying that she is going to go to the pharmacy, but she may never pick up that prescription. She likely leaves my office feeling unheard; her needs are unmet. I move onto the next patient. I feel good, but in actuality, I didn’t hear her. I have provided her bias and stereotyped care. I missed an opportunity to truly engage this patient and her care, and my good intentions of following the literature about her experience in menopause have contributed quite likely to her increased morbidity and mortality, her increased cardiovascular disease risk, all because I have not held space for her cultural identity.

OBG Management caught up with Drs. Jan Shifren and Genevieve Neal-Perry while they were attending the annual meeting of The North American Menopause Society (NAMS), held October 12-15, 2022, in Atlanta, Georgia. Dr. Shifren presented on the “Ins and Outs of Hormone Therapy,” while Dr. Neal-Perry focused on “Menopause Physiology.” 

Evaluating symptomatic patients for appropriate hormone therapy

OBG Management: In your presentation to the group at the NAMS meeting, you described a 51-year-old patient with the principal symptoms of frequent hot flashes and night sweats, sleep disruption, fatigue, irritability, vaginal dryness, and dyspareunia. As she reported already trying several lifestyle modification approaches, what are your questions for her to determine whether hormone therapy (HT), systemic or low-dose vaginal, is advisable?

Jan Shifren, MD: As with every patient, you need to begin with a thorough history and confirm her physical exam is up to date. If there are concerns related to genitourinary symptoms of menopause (GSM), then a pelvic exam is indicated. This patient is a healthy menopausal woman with bothersome hot flashes, night sweats, and vaginal dryness. Sleep disruption from night sweats is likely the cause of her fatigue and irritability, and her dyspareunia due to atrophic vulvovaginal changes. The principal indication for systemic HT is bothersome vasomotor symptoms (VMS), and a healthy woman who is under age 60 or within 10 years of the onset of menopause is generally a very good candidate for hormones. For this healthy 51-year-old with bothersome VMS unresponsive to lifestyle modification, the benefits of HT should outweigh potential risks. As low-dose vaginal estrogen therapy is minimally absorbed and very safe, this would be recommended instead of systemic HT if her only menopause symptoms were vaginal dryness and dyspareunia.

HT types and formulations

OBG Management: For this patient, low-dose vaginal estrogen is appropriate. In general, how do you decide on recommendations for combination therapy or estrogen only, and what formulations and dosages do you recommend?

Dr. Shifren: Any woman with a uterus needs to take a progestogen together with estrogen to protect her uterus from estrogen-induced endometrial overgrowth. With low dose vaginal estrogen therapy, however, concurrent progestogen is not needed.

Continue to: Estrogen options...

Many of our patients like the idea that they are using “natural” HT. I inform them that bioidentical is a marketing term rather than a medical term, but if their goal is to take the same hormones that their ovaries made when they were younger, they should use FDA-approved formulations of estradiol and progesterone for their menopausal HT symptoms. I do not recommend compounded bioidentical HT due to concerns regarding product quality and safety. The combination of FDA-approved estradiol patches and oral micronized progesterone provides a high quality, carefully regulated bioidentical HT regimen. For women greatly preferring an oral estrogen, oral estradiol with micronized progesterone is an option.

In addition to patient preference for natural HT, the reasons that I encourage women to consider the estradiol transdermal patch for their menopausal HT include:

1. no increased risk of venous thromboembolic events when physiologically dosed menopausal estradiol therapy is provided by a skin patch (observational data).¹ With oral estrogens, even when dosed for menopause, VTE risk increases, as coagulation factors increase due to the first-pass hepatic effect. This does not occur with non-oral menopausal estrogens.
2. no increased risk of gallbladder disease, which occurs with oral estrogen therapy (observational data)²
3. possibly lower risk of stroke when low-dose menopausal HT is provided via skin patch (observational data)³
4. convenience—the patches are changed once or twice weekly
5. wide range of doses available, which optimizes identifying the lowest effective dose and decreasing the dose over time.

Progestogen options. Progestogens may be given daily or cyclically. Use of daily progestogen typically results in amenorrhea, which is preferred by most women. Cyclic use of a progestogen for 12-14 days each month results in a monthly withdrawal bleed, which is a good option for a woman experiencing bothersome breakthrough bleeding with daily progestogen. Use of a progestogen-releasing IUD is an off-label alternative for endometrial protection with menopausal HT. As discussed earlier, as many women prefer bioidentical HT, one of our preferred regimens is to provide transdermal estradiol with FDA-approved oral micronized progesterone. There are several patches that combine estradiol with a progestogen, but there is not a lot of dosing flexibility and product choice. There also is an approved product available that combines oral estradiol and micronized progesterone in one tablet.

Scheduling follow-up

OBG Management: Now that you have started the opening case patient on HT, how often are you going to monitor her for treatment?

Dr. Shifren: Women will not experience maximum efficacy for hot flash relief from their estrogen therapy for 3 months, so I typically see a patient back at 3 to 4 months to assess side effects and symptom control. I encourage women to reach out sooner if they are having a bothersome side effect. Once she is doing well on an HT regimen, we assess risks and benefits of ongoing treatment annually. The goal is to be certain she is on the lowest dose of estrogen that treats her symptoms, and we slowly decrease the estrogen dose over time.

Breast cancer risk

OBG Management: In your presentation, you mentioned that the risk of breast cancer does not increase appreciably with short-term use of HT. Is it possible to define short term?

Dr. Shifren: In the Women’s Health Initiative (WHI), a large double-blind, randomized, placebo-controlled trial of menopausal HT, there was a slight increase in breast cancer risk after approximately 4 to 5 years of use in women using estrogen with progestogen.⁴ I share with patients that this increased risk is about the same as that of obesity or drinking more than 1 alcoholic beverage daily. As an increased risk of breast cancer does not occur for several years, a woman may be able to take hormones for bothersome symptoms, feel well, and slowly come off without incurring significant breast cancer risk. In the WHI, there was no increase in breast cancer risk in women without a uterus randomized to estrogen alone.

Regarding cardiovascular risk, in the WHI, an increased risk of cardiovascular events generally was not seen in healthy women younger than age 60 and within 10 years of the onset of menopause.⁵ Benefits of HT may not outweigh risks for women with significant underlying cardiovascular risk factors, even if they are younger and close to menopause onset.

Continue to: The importance of shared decision making...

Dr. Shifren: As with any important health care decision, women should be involved in an individualized discussion of risks and benefits, with shared decision making about whether HT is the right choice. Women also should be involved in ongoing decisions regarding HT formulation, dose, and duration of use.

A nonhormonal option for hot flashes

OBG Management: How many women experience VMS around the time of menopause?

Dr. Genevieve Neal-Perry, MD, PhD: About 60% to 70% of individuals will experience hot flashes around the time of the menopause.⁶ Of those, about 40% are what we would call moderate to severe hot flashes—which are typically the most disruptive in terms of quality of life.⁷ The window of time in which they are likely to have them, at typically their most intense timeframe, is 2 years before the final menstrual period and the year after.⁷ In terms of the average duration, however, it’s about 7 years, which is a lot longer than what we previously thought.⁸ Moreover, there are disparities in that women of color, particularly African American women, can have them as long as 10 years.⁸

Multiethnic differences in the menopause experience

Minority women, or racial and ethnic women, perceived the transition to menopause more positively, and generally took on a posture of acceptance, reporting feeling liberated from many of the challenges associated with the reproductive period. In addition, many associated a greater sense of maturity and respect within their communities with the natural aging process.
2. Optimism. Ethnic women tended to embrace menopause, using humor and laughter to express emotions during stressful life changes. This runs counter to many of the perspectives reported by White women, who often viewed the menopausal transition and aging negatively, as we equate aging with the loss of youthfulness in the United States.
3. Unique, not universal. Most of the ethnic minority women thought that there was something unique about their menopausal experiences, and that they were influenced by immigration transition, financial situations, etc. Many White woman perceived that the menopausal experience was shared among all women.
4. Closed, not open. There were differences in how we talk about symptoms, or whether or not we talk about them at all. Ethnic women tended to be silent about their symptoms. By contrast, White women tended to be more open and talkative and communicative about their symptoms.
5. Minimizing, not controlling. No symptom management was the strategy of choice for most women. Minority women tended to manage their symptoms by tolerating and normalizing them. Only those women with the most serious symptoms sought out medication for temporary relief. Some expressed a tendency to downplay their symptoms because many of them had more important things that they were dealing with in their lives.

What is an individual social identity?

An individual social identity reflects the many groups to which one belongs. It is how one shows up, and yet it is much more than how they physically show up. When you pass your eye on patients, you are only seeing the tip of the iceberg. The full social identity of a patient resides below the surface. Social identity is complex, on a continuum, and can change depending on time and place. How we prioritize our social identities may change, depending on the context and the situation.

Our intersecting social identities give rise to our cultural identity, and it is through the prism of intersectionality that we can understand the ways in which our social identities converge to give rise to disparities in health care in midlife and menopausal women. Holding space for cultural identity, we can impact how our patients are perceiving their menopause, how they are moving through decision making about taking care of themselves in menopause. And we can provide more responsive care to their cultural identities, and hopefully at the end of the day we reduce some of these disparities that we are seeing in our menopausal patients and also are reducing our unconscious bias in our patient interactions.

Culturally responsive care

There are several components to home in on when we are trying to provide culturally responsive care to patients.

1. A commitment to being culturally curious. We have to accept what the literature is sharing with us, that there is not a universal menopausal experience. We have for far too long applied this universal experience of menopause that has largely been based on White women to different racial and ethnic populations.
2. Recognizing. I appreciate that my identity as a Black woman may be very different from other Black women in the room, or whatever their social identity. I am not expected to understand all of the others’ experiences, and I don’t expect that for you either.
3. Acknowledge unconscious implicit biases. Acknowledge the groups to which you have a strong implicit bias, and allow it to drive you to reduce barriers to engaging with patients.
4. Connecting with the individual patient. It is through a process of individuating that we learn from our patients’ unique characteristics, rather than relying on assumptions and stereotypes. We have a window of opportunity to see our patient and move beyond thinking of them in terms of racial and ethnic stereotypes or particular social groups. It is through this process of individualizing that we can seek answers to key questions.

The ultimate goal is to understand our individual patients’ perceptions, outlook on menopause, and contextual factors in their lives that influence the menopause journey.

CASE ENCOUNTER

I quickly look at the patient-filled form before I knock on the exam door, and I see that the patient has checked off that she has hot flashes, night sweats, and I make a mental note, she’s menopausal. I already have a preliminary plan to give this patient hormone therapy. I open the door, and I see that she’s Black. I know, based upon the data from SWAN and others, that her menopause means longer duration, more severe vasomotor symptoms. I have already teed up a prescription to go to the pharmacy.

The problem is, I have not even talked to her. She may actually nod her head, saying that she is going to go to the pharmacy, but she may never pick up that prescription. She likely leaves my office feeling unheard; her needs are unmet. I move onto the next patient. I feel good, but in actuality, I didn’t hear her. I have provided her bias and stereotyped care. I missed an opportunity to truly engage this patient and her care, and my good intentions of following the literature about her experience in menopause have contributed quite likely to her increased morbidity and mortality, her increased cardiovascular disease risk, all because I have not held space for her cultural identity.

OBG Management caught up with Drs. Jan Shifren and Genevieve Neal-Perry while they were attending the annual meeting of The North American Menopause Society (NAMS), held October 12-15, 2022, in Atlanta, Georgia. Dr. Shifren presented on the “Ins and Outs of Hormone Therapy,” while Dr. Neal-Perry focused on “Menopause Physiology.” 

Evaluating symptomatic patients for appropriate hormone therapy

OBG Management: In your presentation to the group at the NAMS meeting, you described a 51-year-old patient with the principal symptoms of frequent hot flashes and night sweats, sleep disruption, fatigue, irritability, vaginal dryness, and dyspareunia. As she reported already trying several lifestyle modification approaches, what are your questions for her to determine whether hormone therapy (HT), systemic or low-dose vaginal, is advisable?

Jan Shifren, MD: As with every patient, you need to begin with a thorough history and confirm her physical exam is up to date. If there are concerns related to genitourinary symptoms of menopause (GSM), then a pelvic exam is indicated. This patient is a healthy menopausal woman with bothersome hot flashes, night sweats, and vaginal dryness. Sleep disruption from night sweats is likely the cause of her fatigue and irritability, and her dyspareunia due to atrophic vulvovaginal changes. The principal indication for systemic HT is bothersome vasomotor symptoms (VMS), and a healthy woman who is under age 60 or within 10 years of the onset of menopause is generally a very good candidate for hormones. For this healthy 51-year-old with bothersome VMS unresponsive to lifestyle modification, the benefits of HT should outweigh potential risks. As low-dose vaginal estrogen therapy is minimally absorbed and very safe, this would be recommended instead of systemic HT if her only menopause symptoms were vaginal dryness and dyspareunia.

HT types and formulations

OBG Management: For this patient, low-dose vaginal estrogen is appropriate. In general, how do you decide on recommendations for combination therapy or estrogen only, and what formulations and dosages do you recommend?

Dr. Shifren: Any woman with a uterus needs to take a progestogen together with estrogen to protect her uterus from estrogen-induced endometrial overgrowth. With low dose vaginal estrogen therapy, however, concurrent progestogen is not needed.

Continue to: Estrogen options...

Many of our patients like the idea that they are using “natural” HT. I inform them that bioidentical is a marketing term rather than a medical term, but if their goal is to take the same hormones that their ovaries made when they were younger, they should use FDA-approved formulations of estradiol and progesterone for their menopausal HT symptoms. I do not recommend compounded bioidentical HT due to concerns regarding product quality and safety. The combination of FDA-approved estradiol patches and oral micronized progesterone provides a high quality, carefully regulated bioidentical HT regimen. For women greatly preferring an oral estrogen, oral estradiol with micronized progesterone is an option.

In addition to patient preference for natural HT, the reasons that I encourage women to consider the estradiol transdermal patch for their menopausal HT include:

1. no increased risk of venous thromboembolic events when physiologically dosed menopausal estradiol therapy is provided by a skin patch (observational data).¹ With oral estrogens, even when dosed for menopause, VTE risk increases, as coagulation factors increase due to the first-pass hepatic effect. This does not occur with non-oral menopausal estrogens.
2. no increased risk of gallbladder disease, which occurs with oral estrogen therapy (observational data)²
3. possibly lower risk of stroke when low-dose menopausal HT is provided via skin patch (observational data)³
4. convenience—the patches are changed once or twice weekly
5. wide range of doses available, which optimizes identifying the lowest effective dose and decreasing the dose over time.

Progestogen options. Progestogens may be given daily or cyclically. Use of daily progestogen typically results in amenorrhea, which is preferred by most women. Cyclic use of a progestogen for 12-14 days each month results in a monthly withdrawal bleed, which is a good option for a woman experiencing bothersome breakthrough bleeding with daily progestogen. Use of a progestogen-releasing IUD is an off-label alternative for endometrial protection with menopausal HT. As discussed earlier, as many women prefer bioidentical HT, one of our preferred regimens is to provide transdermal estradiol with FDA-approved oral micronized progesterone. There are several patches that combine estradiol with a progestogen, but there is not a lot of dosing flexibility and product choice. There also is an approved product available that combines oral estradiol and micronized progesterone in one tablet.

Scheduling follow-up

OBG Management: Now that you have started the opening case patient on HT, how often are you going to monitor her for treatment?

Dr. Shifren: Women will not experience maximum efficacy for hot flash relief from their estrogen therapy for 3 months, so I typically see a patient back at 3 to 4 months to assess side effects and symptom control. I encourage women to reach out sooner if they are having a bothersome side effect. Once she is doing well on an HT regimen, we assess risks and benefits of ongoing treatment annually. The goal is to be certain she is on the lowest dose of estrogen that treats her symptoms, and we slowly decrease the estrogen dose over time.

Breast cancer risk

OBG Management: In your presentation, you mentioned that the risk of breast cancer does not increase appreciably with short-term use of HT. Is it possible to define short term?

Dr. Shifren: In the Women’s Health Initiative (WHI), a large double-blind, randomized, placebo-controlled trial of menopausal HT, there was a slight increase in breast cancer risk after approximately 4 to 5 years of use in women using estrogen with progestogen.⁴ I share with patients that this increased risk is about the same as that of obesity or drinking more than 1 alcoholic beverage daily. As an increased risk of breast cancer does not occur for several years, a woman may be able to take hormones for bothersome symptoms, feel well, and slowly come off without incurring significant breast cancer risk. In the WHI, there was no increase in breast cancer risk in women without a uterus randomized to estrogen alone.

Regarding cardiovascular risk, in the WHI, an increased risk of cardiovascular events generally was not seen in healthy women younger than age 60 and within 10 years of the onset of menopause.⁵ Benefits of HT may not outweigh risks for women with significant underlying cardiovascular risk factors, even if they are younger and close to menopause onset.

Continue to: The importance of shared decision making...

Dr. Shifren: As with any important health care decision, women should be involved in an individualized discussion of risks and benefits, with shared decision making about whether HT is the right choice. Women also should be involved in ongoing decisions regarding HT formulation, dose, and duration of use.

A nonhormonal option for hot flashes

OBG Management: How many women experience VMS around the time of menopause?

Dr. Genevieve Neal-Perry, MD, PhD: About 60% to 70% of individuals will experience hot flashes around the time of the menopause.⁶ Of those, about 40% are what we would call moderate to severe hot flashes—which are typically the most disruptive in terms of quality of life.⁷ The window of time in which they are likely to have them, at typically their most intense timeframe, is 2 years before the final menstrual period and the year after.⁷ In terms of the average duration, however, it’s about 7 years, which is a lot longer than what we previously thought.⁸ Moreover, there are disparities in that women of color, particularly African American women, can have them as long as 10 years.⁸
 

OBG Management: Can you explain why the VMS occur, and specifically around the time of menopause?

Dr. Neal-Perry: For many years we did not understand the basic biology of hot flashes. When you think about it, it’s completely amazing—when half of our population experiences hot flashes, and we don’t understand why, and we don’t have therapy that specifically targets hot flashes.

What we now know from work completed by Naomi Rance, in particular, is that a specific region of the brain, the hypothalamus, exhibited changes in number of neurons that seemed to be increased in size in menopausal people and smaller in size in people who were not menopausal.⁹ That started the journey to understanding the biology, and eventual mechanism, of hot flashes. It took about 10-15 years before we really began to understand why.

What we know now is that estrogen, a hormone that is made by the ovaries, activates and inactivates neurons located in the hypothalamus, a brain region that controls our thermoregulation—the way your body perceives temperature. The hypothalamus controls your response to temperature, either you experience chills or you dissipate heat by vasodilating (hot flush) and sweating.

The thermoregulatory region of the hypothalamus houses cells that receive messages from KNDy neurons, neurons also located in the hypothalamus that express kisspeptin, neurokinin, and dynorphin. Importantly, KNDy neurons express estrogen receptors. (The way that I like to think about estrogen and estrogen receptors is that estrogen is like the ball and the receptor is like the catcher’s mitt.) When estrogen interacts with this receptor, it keeps KNDy neurons quiet. But the increased variability and loss of estrogen that occurs around the time of menopause “disinhibits” KNDy neurons—meaning that they are no longer being reined in by estrogen. In response to decreased estrogen regulation, KNDy neurons become hypertrophied with neurotransmitters and more active. Specifically, KNDy neurons release neurokinin, a neuropeptide that self-stimulates KNDy neurons and activates neurons in the thermoregulatory zone of the brain—it’s a speed-forward feed-backward mechanism. The thermoregulatory neurons interpret this signal as “I feel hot,” and the body begins a series of functions to cool things down.

ILLUSTRATION: KIMBERLY MARTENS FOR OBG MANAGEMENT

Continue to: Treatments that act on the thermoregulatory region

Dr. Neal-Perry: I have described what happens in the brain around the time of menopause, and what triggers those hot flashes.

Estrogen. The reason that estrogen worked to treat the hot flashes is because estrogen inhibits and calms the neurons that become hyperactive during the menopause.

Fezolinetant. Fezolinetant is unique because it specifically targets the hormone receptor that triggers hot flashes, the neurokinin receptor. Fezolinetant is a nonhormone therapy that not only reduces the activity of KNDy neurons but also blocks the effects of neurons in the thermoregulatory zone, thereby reducing the sensation of the hot flashes. We are in such a special time in medical history for individuals who experience hot flashes because now we understand the basic biology of hot flashes, and we can generate targeted therapy to manage hot flashes—that is for both individuals who identify as women and individuals who identify as men, because both experience hot flashes.
 

OBG Management: Is there a particular threshold of hot flash symptoms that is considered important to treat, or is treatment based on essentially the bother to patients?

Dr. Neal-Perry: Treatment is solely based on if it bothers the patient. But we do know that people who have lots of bothersome hot flashes have a higher risk for heart disease and may have sleep disruption, reduced cognitive function, and poorer quality of life. Sleep dysfunction can impact the ability to think and function and can put those affected at increased risk for accidents.

For people who are having these symptoms that are disruptive to their life, you do want to treat them. You might say, “Well, we’ve had estrogen, why not use estrogen,” right? Well estrogen works very well, but there are lots of people who can’t use estrogen—individuals who have breast cancer, blood clotting disorders, significant heart disease, or diabetes. Then there are just some people who don’t feel comfortable using estrogen.

We have had a huge gap in care for individuals who experience hot flashes and who are ineligible for menopausal HT. While there are other nonhormonal options, they often have side effects like sexual dysfunction, hypersomnolence, or insomnia. Some people choose not to use these nonhormonal treatments because the side effects are worse for them than to trying to manage the hot flashes. The introduction to a nonhormonal therapy that is effective and does not have lots of side effects is exciting and will be welcomed by many who have not found relief.
 

OBG Management: Is fezolinetant available now for patients?

Dr. Neal-Perry: It is not available yet. Hopefully, it will be approved within the next year. Astellas recently completed a double blind randomized cross over design phase 3 study that found fezolinetant is highly effective for the management of hot flashes and that it has a low side effect profile.¹⁰ Fezolinetant’s most common side effect was COVID-19, a reflection of the fact that the trial was done during the COVID pandemic. The other most common side effect was headache. Everything else was minimal.

Other drugs in the same class as fezolinetant have been under development for the management of hot flashes; however, they encountered liver function challenges, and studies were stopped. Fezolinetant did not cause liver dysfunction.

Hot flash modifiers

OBG Management: Referring to that neuropathway, are there physiologic differences among women who do and do not experience hot flashes, and are there particular mechanisms that may protect patients against being bothered by hot flashes?

Dr. Neal-Perry: Well, there are some things that we can control, and there are things that we cannot control (like our genetic background). Some of the processes that are important for estrogen receptor function and estrogen metabolism, as well as some other receptor systems, can work differently. When estrogen metabolism is slightly different, it could result in reduced estrogen receptor activity and more hot flashes. Then there are some receptor polymorphisms that can increase or reduce the risk for hot flashes—the genetic piece.¹¹

There are things that can modify your risk for hot flashes and the duration of hot flashes. Individuals who are obese or smoke may experience more hot flashes. Women of color, especially African American women, tend to have hot flashes occur earlier in their reproductive life and last for a longer duration; hot flashes may occur up to 2 years before menopause, last for more than 10 years, and be more disruptive. By contrast, Asian women tend to report fewer and less disruptive hot flashes.⁸
 

OBG Management: If fezolinetant were to be FDA approved, will there be particular patients that it will most appropriate for, since it is an estrogen alternative?

Dr. Neal-Perry: Yes, there may be different patients who might benefit from fezolinetant. This will depend on what the situation is—patients who have breast cancer, poorly controlled diabetes, or heart disease, and those patients who prefer not to use estrogen will benefit from fezolinetant, as we are going to look for other treatment options for those individuals. It will be important for medical providers to listen to their patients and understand the medical background of that individual to really define what is the best next step for the management of their hot flashes.

This is an exciting time for individuals affected by menopausal hot flashes; to understand the biology of hot flashes gives us real opportunities to bridge gaps around how to manage them. Individuals who experience hot flashes will know that they don’t have to suffer, that there are other options that are safe, that can help meet their needs and put them in a better place. ●

Multiethnic differences in the menopause experience

---

Excerpted from the presentation, “Do you see me? Culturally responsive care in menopause,” by Makeba Williams, MD, NCMP, at The North American Menopause Society meeting in Atlanta, Georgia, October 12-15, 2022.

Dr. Williams is Vice Chair of Professional Development and Wellness, Associate Professor, Washington University School of Medicine

The Study of Women’s Health Across the Nation (SWAN) challenged the notion that there is a universal menopausal experience.¹ Up until that time, we had been using this universal experience that is based largely on the experiences of White women and applying that data to the experiences of women of color. Other research has shown that African American women have poorer quality of life and health status, and that they receive less treatment for a number of conditions.^2,3

In a recent review of more than 20 years of literature, we found only 17 articles that met the inclusion criteria, reflecting the invisibility of African American women and other ethnic and racial minorities in the menopause literature and research. Key findings included that African American women^1,4:

• experience an earlier age of onset of menopause
• have higher rates of premature menopause and early menopause, which is a risk factor for cardiovascular disease
• experience a longer time of the menopausal transition, with variability in the average age of menopause onset
• overall report lower rates of vaginal symptoms
• are less likely to report sleep disturbances than White women or Hispanic women, but more likely to report these symptoms than Asian women
• experience a higher prevalence, frequency, and severity of vasomotor symptoms (VMS), and were more bothered by those symptoms

− 48.4 years in the Healthy Women’s Study

− 50.9 years in the Penn Ovarian Aging Study

− 51.4 years in SWAN

• reported lower educational attainment, experiencing more socioeconomic disadvantage and exposure to more adverse life effects
• receive less treatment for VMS, hypertension, and depression, and are less likely to be prescribed statin drugs
• experience more discrimination
• use cigarettes and tobacco more, but are less likely to use alcohol and less likely to have physical activity.

Cultural influences on menopause

Im and colleagues have published many studies looking at cultural influences on African American, Hispanic, and Asian American women, and comparing them to White women.⁵ Notable differences were found regarding education level, family income, employment, number of children, and greater perceived health (which is associated with fewer menopausal symptoms). They identified 5 qualitative ideas:

1. Positive acceptance. Minority women, or racial and ethnic women, perceived the transition to menopause more positively, and generally took on a posture of acceptance, reporting feeling liberated from many of the challenges associated with the reproductive period. In addition, many associated a greater sense of maturity and respect within their communities with the natural aging process.
2. Optimism. Ethnic women tended to embrace menopause, using humor and laughter to express emotions during stressful life changes. This runs counter to many of the perspectives reported by White women, who often viewed the menopausal transition and aging negatively, as we equate aging with the loss of youthfulness in the United States.
3. Unique, not universal. Most of the ethnic minority women thought that there was something unique about their menopausal experiences, and that they were influenced by immigration transition, financial situations, etc. Many White woman perceived that the menopausal experience was shared among all women.
4. Closed, not open. There were differences in how we talk about symptoms, or whether or not we talk about them at all. Ethnic women tended to be silent about their symptoms. By contrast, White women tended to be more open and talkative and communicative about their symptoms.
5. Minimizing, not controlling. No symptom management was the strategy of choice for most women. Minority women tended to manage their symptoms by tolerating and normalizing them. Only those women with the most serious symptoms sought out medication for temporary relief. Some expressed a tendency to downplay their symptoms because many of them had more important things that they were dealing with in their lives.

What is an individual social identity?

An individual social identity reflects the many groups to which one belongs. It is how one shows up, and yet it is much more than how they physically show up. When you pass your eye on patients, you are only seeing the tip of the iceberg. The full social identity of a patient resides below the surface. Social identity is complex, on a continuum, and can change depending on time and place. How we prioritize our social identities may change, depending on the context and the situation.

Our intersecting social identities give rise to our cultural identity, and it is through the prism of intersectionality that we can understand the ways in which our social identities converge to give rise to disparities in health care in midlife and menopausal women.

People with subclinical hyperthyroidism are at 34% greater risk of experiencing a fracture compared with those with normal thyroid function, new research shows.

The finding, from a study of nearly 11,000 middle-aged men and women followed for a median of 2 decades, “highlights a potential role for more aggressive screening and monitoring of patients with subclinical hyperthyroidism to prevent bone mineral disease,” the researchers wrote.

Primary care physicians “should be more aware of the risks for fracture among persons with subclinical hyperthyroidism in the ambulatory setting,” Natalie R. Daya, a PhD student in epidemiology at Johns Hopkins Bloomberg School of Public Health, Baltimore, and first author of the study, told this news organization.

Ms. Daya and her colleagues published their findings in JAMA Network Open.

 

Building on earlier findings

The results agree with previous work, including a meta-analysis of 13 prospective cohort studies of 70,289 primarily White individuals with an average age of 64 years, which found that subclinical hyperthyroidism was associated with a modestly increased risk for fractures, the researchers noted.

“Our study extends these findings to a younger, community-based cohort that included both Black and White participants, included extensive adjustment for potential confounders, and had a longer follow-up period (median follow-up of 21 years vs. 12 years),” they wrote.

The study included 10,946 participants in the Atherosclerosis Risk in Communities Study who were recruited in Washington County, Maryland; Forsyth County, North Carolina; Jackson, Mississippi; and the suburbs of Minneapolis.

Baseline thyroid function was measured in blood samples collected during the second visit, which occurred between 1990 and 1992. No participants in the new analysis took thyroid medications or had a history of hospitalization for fractures at baseline, and all identified as Black or White. The mean age was 57 years, 24% were Black, and 54.3% were female.

Subclinical hyperthyroidism was defined as a thyrotropin level less than 0.56 mIU/L; subclinical hypothyroidism as a thyrotropin level greater than 5.1 mIU/L; and normal thyroid function as a thyrotropin level between 0.56 and 5.1 mIU/L, with normal free thyroxine levels of 0.85-1.4 ng/dL.

The vast majority (93%) of participants had normal thyroid function, 2.6% had subclinical hyperthyroidism, and 4.4% had subclinical hypothyroidism, according to the researchers.

Median follow-up was 21 years. The researchers identified 3,556 incident fractures, detected with hospitalization discharge codes through 2019 and inpatient and Medicare claims data through 2018, for a rate of 167.1 per 10,000 person-years.

Adjusted hazard ratios for fracture were 1.34 (95% confidence interval [CI], 1.09-1.65) for people with subclinical hyperthyroidism and 0.90 (95% CI, 0.77-1.05) for those with subclinical hypothyroidism, compared with those with normal thyroid function.

Most fractures occurred in either the hip (14.1%) or spine (13.8%), according to the researchers.

Limitations included a lack of thyroid function data during the follow-up period and lack of data on bone mineral density, the researchers wrote.
 

‘An important risk factor’

Endocrinologist Michael McClung, MD, founding and emeritus director of the Oregon Osteoporosis Center, Portland, who was not involved in the study, pointed out that both subclinical hypothyroidism and subclinical hyperthyroidism have been linked to greater risk for cardiovascular disease as well as fracture.

The new paper underscores that subclinical hyperthyroidism “should be included as an important risk factor” for fracture as well as cardiovascular risk, Dr. McClung said in an interview. In considering whether to treat osteoporosis, subclinical hyperthyroidism “may be enough to tip the balance in favor of pharmacological therapy,” he added.

Thyroid-stimulating hormone (TSH) tests to assess thyroid function are typically ordered only if a patient has symptoms of hyperthyroidism or hypothyroidism, Ms. Daya said. Depending on the cause and severity of a low TSH level, a physician may prescribe methimazole or radioactive iodine therapy to reduce the production of thyroxine, she said.

However, well-designed studies are needed to evaluate whether treatment of subclinical thyroid dysfunction reduces the risk for fracture or cardiovascular problems and assess downsides such as side effects, costs, and psychological harm, Dr. McClung noted.

The U.S. Preventive Services Task Force concluded in 2015 that the data were insufficient to recommend screening for thyroid dysfunction in adults without symptoms. As of a year ago, no new evidence has emerged to support an update, according to the task force’s website.

“Until those studies are available, selective screening of thyroid function should be considered in all patients undergoing risk assessment for cardiovascular disease or skeletal health,” Dr. McClung said.

The Atherosclerosis Risk in Communities Study has been funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) and the U.S. Department of Health and Human Services. Ms. Daya and four study authors reported receiving NIH grants during the study period. Dr. McClung reported no relevant financial conflicts of interest.

People with subclinical hyperthyroidism are at 34% greater risk of experiencing a fracture compared with those with normal thyroid function, new research shows.

The finding, from a study of nearly 11,000 middle-aged men and women followed for a median of 2 decades, “highlights a potential role for more aggressive screening and monitoring of patients with subclinical hyperthyroidism to prevent bone mineral disease,” the researchers wrote.

Primary care physicians “should be more aware of the risks for fracture among persons with subclinical hyperthyroidism in the ambulatory setting,” Natalie R. Daya, a PhD student in epidemiology at Johns Hopkins Bloomberg School of Public Health, Baltimore, and first author of the study, told this news organization.

Ms. Daya and her colleagues published their findings in JAMA Network Open.

 

Building on earlier findings

The results agree with previous work, including a meta-analysis of 13 prospective cohort studies of 70,289 primarily White individuals with an average age of 64 years, which found that subclinical hyperthyroidism was associated with a modestly increased risk for fractures, the researchers noted.

“Our study extends these findings to a younger, community-based cohort that included both Black and White participants, included extensive adjustment for potential confounders, and had a longer follow-up period (median follow-up of 21 years vs. 12 years),” they wrote.

The study included 10,946 participants in the Atherosclerosis Risk in Communities Study who were recruited in Washington County, Maryland; Forsyth County, North Carolina; Jackson, Mississippi; and the suburbs of Minneapolis.

Baseline thyroid function was measured in blood samples collected during the second visit, which occurred between 1990 and 1992. No participants in the new analysis took thyroid medications or had a history of hospitalization for fractures at baseline, and all identified as Black or White. The mean age was 57 years, 24% were Black, and 54.3% were female.

Subclinical hyperthyroidism was defined as a thyrotropin level less than 0.56 mIU/L; subclinical hypothyroidism as a thyrotropin level greater than 5.1 mIU/L; and normal thyroid function as a thyrotropin level between 0.56 and 5.1 mIU/L, with normal free thyroxine levels of 0.85-1.4 ng/dL.

The vast majority (93%) of participants had normal thyroid function, 2.6% had subclinical hyperthyroidism, and 4.4% had subclinical hypothyroidism, according to the researchers.

Median follow-up was 21 years. The researchers identified 3,556 incident fractures, detected with hospitalization discharge codes through 2019 and inpatient and Medicare claims data through 2018, for a rate of 167.1 per 10,000 person-years.

Adjusted hazard ratios for fracture were 1.34 (95% confidence interval [CI], 1.09-1.65) for people with subclinical hyperthyroidism and 0.90 (95% CI, 0.77-1.05) for those with subclinical hypothyroidism, compared with those with normal thyroid function.

Most fractures occurred in either the hip (14.1%) or spine (13.8%), according to the researchers.

Limitations included a lack of thyroid function data during the follow-up period and lack of data on bone mineral density, the researchers wrote.
 

‘An important risk factor’

Endocrinologist Michael McClung, MD, founding and emeritus director of the Oregon Osteoporosis Center, Portland, who was not involved in the study, pointed out that both subclinical hypothyroidism and subclinical hyperthyroidism have been linked to greater risk for cardiovascular disease as well as fracture.
