Soy didn’t up all-cause mortality in breast cancer survivors
A cohort of Chinese women who are breast cancer survivors had no increased mortality from soy intake, according to a new study.
The work adds to the existing body of evidence that women with breast cancer, or risk for breast cancer, don’t need to modify their soy intake to mitigate risk, said the study’s first author, Suzanne C. Ho, PhD.
Speaking at the annual meeting of the North American Menopause Society, Dr. Ho noted that the combination of increasing breast cancer incidence and improved outcome has resulted in larger numbers of breast cancer survivors in Hong Kong, where she is professor emerita at the Chinese University of Hong Kong.
The prospective, ongoing study examines the association between soy intake pre- and postdiagnosis and total mortality for Chinese women who are breast cancer survivors. Dr. Ho said that she and her colleagues hypothesized that they would not see higher mortality among women who had higher soy intake – and this was the case.
Of 1,497 breast cancer survivors drawn from two facilities in Hong Kong, those who consumed higher quantities of dietary soy did not have increased risk of all-cause mortality, compared with those in the lowest tertile of soy consumption.
There are theoretical underpinnings for thinking that soy could be a player in cancer risk, but the biochemistry and epidemiology behind the studies are complicated. Estrogen plays a role in human breast cancer, and many modern breast cancer treatments actually dampen endogenous estrogens.
However, epidemiologic data have shown that consumption of soy-based foods – which contain phytoestrogens, primarily in the form of isoflavones – is inversely associated with developing breast cancer.
This is all part of why soy-based foods have been thought of as a mixed bag with regard to breast cancer: Soy isoflavones are, said Dr. Ho, “Natural estrogen receptor modulators that possess both estrogenlike and antiestrogenic properties.”
Other chemicals contained in soy may fight cancer, with effects that are antioxidative and strengthen immune response. Soy constituents also inhibit DNA topoisomerase I and II, proteases, tyrosine kinases, and inositol phosphate, effects that can slow tumor growth. Still, one soy isoflavone, genistein, actually can promote growth of estrogen-dependent tumors in rats, said Dr. Ho
Dr. Ho and her colleagues enrolled Hong Kong residents for the study of mortality among breast cancer survivors. Participants were included if they were Chinese, female, aged 24-77 years, and had their first primary breast cancer histologically confirmed within 12 months of entering the study. Cancer had to be graded below stage III.
Using a 109-item validated food questionnaire, investigators gathered information about participants’ soy intake and general diet for the year prior to breast cancer diagnosis. Other patient characteristics, relevant prognostic information from medical records, and anthropometric data were collected at baseline, and repeated at 18, 36, and 60 months.
The primary outcome measure – all-cause mortality during the follow-up period – was tracked for a mean 50.9 months, with a 78% retention rate for study participants, said Dr. Ho. In total, 96 patients died during follow-up, making up 5.9% of the premenopausal and 7% of the postmenopausal participants.
Statistical analysis corrected for potential confounders, including patient and disease characteristics and treatment modalities, as well as overall energy consumption.
Patients were evenly divided into tertiles of soy isoflavone intake, with cutpoints of 3.77 mg/1,000 kcal and 10.05 mg/1,000 kcal for the lower limit of the two higher tertiles. For the highest tertile, though, mean isoflavone intake was actually 20.87 mg/1,000 kcal.
Patient, disease, and treatment characteristics did not differ significantly among the tertiles.
An adjusted statistical analysis looked at pre- and postmenopausal women separately by tertile of soy isoflavone consumption, setting the hazard ratio for all-cause mortality at 1.00 for women in the lowest tertile of soy consumption.
For premenopausal women in the middle tertile, the HR was 0.45 (95% confidence interval, 0.20-1.00), and 0.86 for those in the highest tertile (95% CI, 0.43-1.72); 782 participants, in all, were premenopausal.
For the 715 postmenopausal women, the HR for those in the middle tertile of soy consumption was 0.94 (95% CI, 0.43-2.05), and 1.11 in the highest (95% CI, 0.54-2.29).
Taking all pre- and postmenopausal participants together, those in the middle tertile of soy isoflavone intake had an all-cause mortality HR of 0.63 (95% CI, 0.37-1.09). For the highest tertile of the full cohort, the HR was 0.95 (95% CI, 0.58-1.55).
Confidence intervals were wide in these findings, but Dr. Ho noted that “moderate soy food intake might be associated with better survival.”
“Prediagnosis soy intake did not increase the risk of all-cause mortality in breast cancer survivors,” said Dr. Ho, findings she called “consistent with the literature that soy consumption does not adversely effect breast cancer survival.”
The study is ongoing, she explained, and “longer follow-up will provide further evidence on the effect of pre- and postdiagnosis soy intake on breast cancer outcomes.”
The study had a homogeneous population of southern Chinese women, with fairly good retention and robust statistical adjustment for confounders. However, it wasn’t possible to assess bioavailability of isoflavones and their metabolites, which can vary according to individual microbiota. Also, researchers did not track whether patients used traditional Chinese medicine.
The World Cancer Research Fund International supported the study. Dr. Ho reported no conflicts of interest.

Estetrol safely limited menopause symptoms in a phase 2b study
Estetrol (Donesta) relieved vasomotor menopausal symptoms without stimulating breast tenderness or raising triglyceride levels in a dose-finding study of the investigational drug presented at the annual meeting of the North American Menopause Society.
Estetrol (E4), an estrogen produced by the fetal liver, is the first native estrogen acting selectively in tissues. Since it crosses the placenta, estetrol is present in maternal urine at about 9 weeks’ gestation. In fetal plasma, it circulates at concentrations about 12 times higher than maternal estetrol levels. The hormone has a half-life of 28-32 hours, longer than the half-life of most other estrogens.
E4 “has been shown to have a remarkably safe profile and I like to describe it as the first natural oral estrogen with the safety profile of a transdermal estrogen,” said Wulf H. Utian, MD, the Arthur H. Bill Professor of Obstetrics & Gynecology at Case Western Reserve University, Cleveland. Estetrol uniquely activates nuclear estrogen receptor–alpha, while antagonizing membrane estrogen receptor-alpha. These properties give E4 selective tissue action, with low breast stimulation meaning less breast tenderness and “low carcinogenic impact.”
Additionally, triglyceride levels are minimally affected, and serum markers for venous thromboembolism generally remain unchanged with E4 exposure, he said.
In a phase 2b dose-finding study, a variety of estetrol doses were compared with placebo to treat vasomotor symptoms in postmenopausal women aged 40-65 years with at least 7 moderate to severe hot flashes daily, or at least 50 moderate to severe hot flashes in the week before randomization. The multicenter, double-blind randomized controlled trial took place in five European countries, with 200 women overall completing the study. The study design excluded women with personal histories of malignancy, thromboembolism, or coagulopathy, and women with diabetes and poor glycemic control. Women with a uterus who had current or past endometrial hyperplasia, polyps, or an abnormal cervical smear were also excluded.
Women who had an intact uterus were included if transvaginal ultrasound showed endometrial thickness of 5 mm or less. Participants were randomized 1:1:1:1 to receive four different E4 doses: 2.5 mg, 5 mg, 10 mg, or 15 mg.
At the highest dose of 15 mg, E4 significantly reduced the frequency of vasomotor symptoms compared with placebo by study week 4 and throughout the 12-week study period (P less than .05).
This high dose also resulted in a 28% reduction in vasomotor symptom severity, compared with placebo by study week 12, with a significant separation from placebo by week 12.
In terms of the number of women who experienced at least a 50% drop in severe vasomotor symptoms, the 15-mg E4 dose also bested placebo (P less than .01). Among the group taking the 15 mg dose, significantly more also saw at least a 75% drop in frequency of severe vasomotor symptom (P less than .001).
Vaginal cytology showed that by week 12 all doses of E4 significantly increased the vaginal maturation index from baseline, a finding that corresponds with less thinning of vaginal tissues (P less than .001, compared with placebo for all doses).
The safety profile of E4 was good, Dr. Utian said. Coagulation markers were unaffected, and most lipid and blood glucose markers were also unchanged. There were “small but potentially beneficial changes in HDL-C [HDL cholesterol levels] and HbA1c values [hemoglobin A1c]” in groups taking the two highest doses of E4.
Also, C-telopeptide of type 1 collagen and osteocalcin values were reduced, “suggesting reduction in bone resorption,” he said.
According to Dr. Utian, those taking the two highest doses also saw a “slight though significant increase” from baseline in sex hormone–binding globulin levels, “indicating that the E4 estrogenic effect was mild and dose dependent.”
Endometrial biopsies showed no hyperplasia. In those taking the 15-mg E4 dose, mean endometrial thickness did increase from a mean 2 mm at baseline to 6 mm at 12 weeks. However, endometrial thickness returned to baseline after progestin therapy, said Dr. Utian. There were no unexpected adverse events during the study.
Dr. Utian reported consultant relationships with Mithra, the maker of estetrol; AMAG; Pharmavite; and Endoceutics. The study was funded by Mithra.

No signal for CV, breast effects with bioidentical vaginal estrogen for dyspareunia
that would suggest significant systemic absorption.
The lack of sex hormone binding globulin (SHBG) changes in the subset of women who received this test bolsters support for low systemic absorption from the low-dose vaginal softgel, Lisa Larkin, MD, said at the annual meeting of the North American Menopause Society in Orlando.
These safety data show that the vaginal route for this hormone is meeting a treatment goal for many menopausal women: “One goal of vaginal estrogen is to minimize systemic absorption and potentially reduce related side effects,” Dr. Larkin said.
TX-004HR (Imvexxy) delivers bioidentical solubilized 17 beta-estradiol (E2) via a softgel vaginal insert. It is Food and Drug Administration approved in 4-mcg and 10-mcg doses for the treatment of moderate to severe dyspareunia associated with menopause.
The phase 3 clinical trial (REJOICE) of TX-004HR met the coprimary endpoints of improving vaginal physiology, lowering vaginal pH, and decreasing the severity of dyspareunia at both the 4- and 10-mcg doses, said Dr. Larkin, an internal medicine physician in private practice in Mariemont, Ohio.
Serum estradiol levels for REJOICE participants were “similar to placebo and baseline, and generally within the postmenopausal range,” she said.
The randomized, double-blind, placebo-controlled trial tested 4-, 10-, and 25-mcg doses of TX-004HR. The self-administered vaginal inserts were used once daily for 2 weeks, then twice weekly for an additional 10 weeks.
In looking at treatment emergent adverse events (TEAEs), the REJOICE investigators were particularly interested in tracking cardiovascular and breast events, Dr. Larkin said. Participants received ECGs and clinical breast exams at baseline, and at study week 12. In addition, 72 of the women had SHBG measured at baseline and at weeks 2 and 12. The trial had a high completion rate of 94% at 12 weeks. The mean age of the women was 59 years, and the mean body mass index was 26.7 kg/m2. African American women made up 12% of the study; the remainder of the women were white.
In the end, 784 menopausal women with moderate to severe dyspareunia were randomized 1:1:1:1 to placebo or to receive one of the three dose levels of TX-004HR. Overall, “no clinically significant differences in adverse events were observed between treatment and placebo groups,” Dr. Larkin said. Only headache, vaginal discharge, and vulvovaginal pruritus occurred in at least 3% of the women in any treatment arm, with no differences between those taking TX-004HR and placebo. There were no malignancies or endometrial hyperplasia among the REJOICE participants: “There was no signal of estrogenic stimulation of the endometrium,” she said.
Looking at cardiovascular-related TEAEs, the five events that occurred were judged to be mild, and mostly not related to treatment. One case of first degree atrioventricular block and one case of sinus bradycardia were reported by the same woman, who was taking the 4-mcg dose of TX-004HR. One additional woman on that dose experienced palpitations, as did one woman taking placebo. “No coronary heart disease, venous thromboembolism, or other thrombotic episodes were noted” during the REJOICE trial, Dr. Larkin said. There were no clinically significant ECG changes during the study period that were judged related to treatment. Blood pressure was mildly increased in three women, one each in the 4-mcg, 10-mcg, and placebo study arms. The elevation was considered possibly related to the study in the 4-mcg and placebo takers. Two other women in the 4-mcg group experienced mild incident hypertension, with one woman’s hypertension judged possibly related to treatment.
Blood chemistry showed incident hypercholesterolemia for one woman in the 4-mcg group and one in the placebo group, and one woman taking the 10-mcg TX-0400HR dose and two taking placebo had increases in serum triglycerides.
Seven women reported breast-related TEAEs, with five of these considered possibly or probably treatment related. One woman on the 10-mcg dose had breast tenderness; all other events were among placebo takers.
Finally, among the subset of women whose SHBG levels were tested, “no dose-related pattern was apparent, and changes with TX-004HR were comparable to changes with placebo,” said Dr. Larkin, noting that there was no suggestion of significant systemic absorption.
“These safety data, in conjunction with the improved moderate to severe dyspareunia efficacy data and minimal estradiol absorption, support a local effect of the TX-004HR vaginal insert,” she said.
The study was sponsored by TherapeuticsMD, the manufacturer of TH-004HR. Dr. Larkin disclosed that she is an advisory board member and on the speaker’s bureau for Valeant pharmaceuticals, is a consultant for TherapeuticsMD, and is an advisory board member for AMAG and Palatin Technologies.

that would suggest significant systemic absorption.
The lack of sex hormone binding globulin (SHBG) changes in the subset of women who received this test bolsters support for low systemic absorption from the low-dose vaginal softgel, Lisa Larkin, MD, said at the annual meeting of the North American Menopause Society in Orlando.
These safety data show that the vaginal route for this hormone is meeting a treatment goal for many menopausal women: “One goal of vaginal estrogen is to minimize systemic absorption and potentially reduce related side effects,” Dr. Larkin said.
TX-004HR (Imvexxy) delivers bioidentical solubilized 17 beta-estradiol (E2) via a softgel vaginal insert. It is Food and Drug Administration approved in 4-mcg and 10-mcg doses for the treatment of moderate to severe dyspareunia associated with menopause.
The phase 3 clinical trial (REJOICE) of TX-004HR met the coprimary endpoints of improving vaginal physiology, lowering vaginal pH, and decreasing the severity of dyspareunia at both the 4- and 10-mcg doses, said Dr. Larkin, an internal medicine physician in private practice in Mariemont, Ohio.
Serum estradiol levels for REJOICE participants were “similar to placebo and baseline, and generally within the postmenopausal range,” she said.
The randomized, double-blind, placebo-controlled trial tested 4-, 10-, and 25-mcg doses of TX-004HR. The self-administered vaginal inserts were used once daily for 2 weeks, then twice weekly for an additional 10 weeks.
In looking at treatment emergent adverse events (TEAEs), the REJOICE investigators were particularly interested in tracking cardiovascular and breast events, Dr. Larkin said. Participants received ECGs and clinical breast exams at baseline, and at study week 12. In addition, 72 of the women had SHBG measured at baseline and at weeks 2 and 12. The trial had a high completion rate of 94% at 12 weeks. The mean age of the women was 59 years, and the mean body mass index was 26.7 kg/m2. African American women made up 12% of the study; the remainder of the women were white.
In the end, 784 menopausal women with moderate to severe dyspareunia were randomized 1:1:1:1 to placebo or to receive one of the three dose levels of TX-004HR. Overall, “no clinically significant differences in adverse events were observed between treatment and placebo groups,” Dr. Larkin said. Only headache, vaginal discharge, and vulvovaginal pruritus occurred in at least 3% of the women in any treatment arm, with no differences between those taking TX-004HR and placebo.

With more mindfulness, menopausal symptoms wane
An observational Furthermore, mindfulness had the greatest positive effect on menopausal symptoms for those women with the highest self-reported stress levels.
“In this cross-sectional study, mindfulness was associated with lower menopausal symptom burden. In women with higher stress, the magnitude of association between mindfulness and menopausal symptoms appeared more robust,” said Richa Sood, MD, speaking at the annual meeting of the North American Menopause Society.
Menopausal symptoms can exist alongside many other midlife issues because women often are trying to keep many balls in the air: This age group may be facing aging parents, a household with teenagers, and work-related pressures, she noted.
Thus, menopausal symptoms can be amplified by stressors. New mood problems – or worsening of preexisting ones – can interfere with work productivity and negatively affect relationships. Life satisfaction can take a steep dive during midlife for some women, said Dr. Sood of the Mayo Clinic, Rochester, Minn.
Could mindfulness be effective for stress management in this complex landscape of physiological and lifespan changes? “Mindfulness is paying attention,” said Dr. Sood. Practitioners of mindfulness focus on purposeful attention, staying in the present moment, and avoiding judgment.
Mindfulness may work as a stress-management tool for a variety of reasons, said Dr. Sood. The technique can help retrain people with tendencies for emotional reactivity in stressful situations; additionally, the focus on the present and on observation, rather than judgment, may help avoid maladaptive rumination.
To see how mindfulness in everyday life could affect the burden of menopausal symptoms, Dr. Sood and her collaborators designed an observational, cross-sectional study of 1,744 women aged 40-64 years.
The investigators used three scales in their assessments. The first, the Menopause Rating Scale (MRS), is an 11-item scale ranging from 0 to 44 that assesses psychological, somatovegetative, and urogenital domains. The second, the Perceived Stress Scale 4 (PSS-4), is a four-item scale that is a global measure of stress over the last 4 weeks, with tallied scores in the 0-16 range. Finally, the Mindful Attention Awareness Scale (MAAS) is a 15-item scale that captures how frequently respondents are in a mindful state during their daily life, with higher scores meaning more mindfulness.
The 1,744 women were seen in a women’s health clinic over the period of one year. Participants were a mean 53.4 years old (standard deviation, 6.1 years). Almost all were white (93%), most were married (82.7%), and most also had at least a 4-year college degree (64.6%) and were employed (65.3%).
The investigators mapped each scale against each of the others, which yielded three plots. In the first, higher MAAS scores were correlated with lower MRS scores (correlation, –0.49; P less than .001), which means that more time in a mindful state was associated with less severe menopausal symptoms.
In the second plot, lower MRS scores were associated with lower PSS-4 scores (correlation, 0.55; P less than .001). The last plot mapped PSS-4 scores against MAAS scores, showing that higher MAAS scores were correlated with lower PSS-4 scores, which means that more time in a mindful state was also associated with less perceived stress (correlation, –0.53; P less than .001).
Most of these associations remained statistically significant after multivariable linear regression analysis and breaking out the subscales of the MRS. Only the association between higher MAAS scores and the somatovegetative domain of the PSS-4 lost significance (P = 0.44).
Next, Dr. Sood and her collaborators probed how higher perceived stress, as measured by higher PSS-4 scores, altered the effects that mindful activity had on menopausal symptoms (as measured by the MRS).
The effect of mindfulness became stronger in the milieu of higher perceived stress. At a relatively low PSS-4 value of 4, the MRS score dropped 1.53 points for each one-point increase in the MAAS total score. However, with a PSS-4 score of 12, the decrease in MRS was 2.27 points for each one-point increase in MAAS, and with the maximum perceived stress score of 16, the MRS fell 2.64 points for each one-point increase in the MAAS score.
These findings are set against the backdrop of previous literature linking mindfulness to positive health behaviors and outcomes, she said, noting that work looking specifically at mindfulness-based stress reduction in peri- and postmenopausal women showed a halving of symptoms and improved quality of life.
Dr. Sood said that the present study was observational only, noting that it looked only at time spent in a mindful state in an untrained cohort of women in midlife. “Trait, or dispositional, mindfulness appears to be protective against stress and symptoms in midlife women,” she commented. “More mindful women may be choosing to shift their attention to more pleasant aspects of life, rather than their symptoms.”
“If you allow me to speculate a bit,” Dr. Sood continued, “the underpinnings of psychological symptoms rest in threat-focused attention and emotional reactivity – so the mindfulness approach appears to fit very well to impact such a change.”
Mindfulness, she added, “might be a tool to impact the emotional component of the overall experience, thereby decreasing the total suffering.” However, she noted that what’s needed are studies with a more heterogeneous population, as well as ones designed to tease out causality. Still, “the current study adds to the wealth of data supporting the role of mindfulness in various settings for impacting positive change in health and behaviors.”
Dr. Sood reported that she has ownership stake in the Global Center for Resiliency and Well-Being.

For dyspareunia, intravaginal prasterone may work best soon after menopause
Neither age nor previous hormone therapy had statistically significant associations with the effect of intravaginal prasterone on dyspareunia severity, according to a new subgroup analysis of clinical trial data. In a trend that did not reach statistical significance, though, said David F. Archer, MD.
“This was an unexpected finding,” he said in an interview.
In a subgroup analysis of data from two clinical trials of intravaginal prasterone (Intrarosa), Dr. Archer and his colleagues sought to investigate whether age, time since menopause, or any previous use of hormone replacement therapy influenced prasterone’s efficacy in treating dyspareunia.
Dr. Archer and his collaborators pooled data from two prospective, randomized, double-blind, placebo-controlled trials (NCT02013544 and NCT01256684) of intravaginal prasterone dosed at 0.50%, 6.5 mg once daily for 12 weeks; he presented the subgroup analyses at the annual meeting of the North American Menopause Society in San Diego.
For each subgroup, Dr. Archer, a professor of obstetrics and gynecology at Eastern Virginia Medical School, Norfolk, and his coinvestigators compared the mean differences in dyspareunia severity score of women who received prasterone and those who received placebo.
All subgroup analyses used the endpoint of improvement in moderate to severe dyspareunia or whether dyspareunia was the most bothersome symptoms for the women participating in the study. The investigators began by looking at the subgroup of 460 women who were 56 years and older at baseline and compared them with the 180 younger participants.
The 283 older participants who received prasterone saw a decrease of 0.36 points in a dyspareunia severity score versus a 0.44 point decrease for the 123 women aged 55 and younger who received prasterone, a nonsignificant difference between subgroups. The decrease compared with placebo-takers was significant in both cases, however (P = .0003 and P =.0031, respectively).
Looking at time since menopause, Dr. Archer and his collaborators divided participants into 33 individuals who were 1 or 2 years post menopause, 86 women who were 3-5 years post menopause, and 521 women who had experienced menopause at least 6 years before study baseline.
In this analysis, 22 of the earliest postmenopause women received prasterone, seeing a 1.59 point drop in dyspareunia severity. For the 59 women in the prasterone study arms who were 3-5 year past menopause, the decrease from baseline was 0.59 points. Finally, among the 325 women who received prasterone and experienced menopause 6 or more years ago, the decrease was 0.27 points.
Although there was a numeric difference in the change in dyspareunia score severity among these groups, the differences were not statistically significant, said Dr. Archer. Again, though, those who took prasterone had a significant reduction in dyspareunia severity scores when compared with those taking placebo (P less than .0001, P = .0136, and P = .0024, respectively).
In the prasterone study arms, 184 had previously used hormone therapy, and 222 had not. After 12 weeks of intravaginal prasterone, there was no statistically significant difference between the two subgroups, with a decreases in dyspareunia severity scores of 0.45 and 0.32, respectively. The decreases in severity scores when compared with those among women who took placebo were again statistically significant for both subgroups, however (P = .0002 and P = .0057, respectively).
Prasterone is a steroid that is also known as dehydroepiandrosterone (DHEA) and is an endogenous hormone that is a precursor for estrogens and androgens. Prasterone’s mechanism of action to reduce vulvar and vaginal atrophy is not completely understood, according to the Food and Drug Administration.
“The nonstatistically significant smaller effect on dyspareunia observed when treatment is initiated after a longer period after menopause suggests that a longer treatment period could be needed to achieve optimal benefit and that treatment of dyspareunia should be initiated as early as possible after menopause,” said Dr. Archer.
Dr. Archer reported grant support from and consulting relationships with several pharmaceutical companies, including Endoceutics, the producer of Intrarosa intravaginal prasterone.
Neither age nor previous hormone therapy had statistically significant associations with the effect of intravaginal prasterone on dyspareunia severity, according to a new subgroup analysis of clinical trial data. In a trend that did not reach statistical significance, though, said David F. Archer, MD.
“This was an unexpected finding,” he said in an interview.
In a subgroup analysis of data from two clinical trials of intravaginal prasterone (Intrarosa), Dr. Archer and his colleagues sought to investigate whether age, time since menopause, or any previous use of hormone replacement therapy influenced prasterone’s efficacy in treating dyspareunia.
Dr. Archer and his collaborators pooled data from two prospective, randomized, double-blind, placebo-controlled trials (NCT02013544 and NCT01256684) of intravaginal prasterone dosed at 0.50%, 6.5 mg once daily for 12 weeks; he presented the subgroup analyses at the annual meeting of the North American Menopause Society in San Diego.
For each subgroup, Dr. Archer, a professor of obstetrics and gynecology at Eastern Virginia Medical School, Norfolk, and his coinvestigators compared the mean differences in dyspareunia severity score of women who received prasterone and those who received placebo.
All subgroup analyses used the endpoint of improvement in moderate to severe dyspareunia or whether dyspareunia was the most bothersome symptoms for the women participating in the study. The investigators began by looking at the subgroup of 460 women who were 56 years and older at baseline and compared them with the 180 younger participants.
The 283 older participants who received prasterone saw a decrease of 0.36 points in a dyspareunia severity score versus a 0.44 point decrease for the 123 women aged 55 and younger who received prasterone, a nonsignificant difference between subgroups. The decrease compared with placebo-takers was significant in both cases, however (P = .0003 and P =.0031, respectively).
Looking at time since menopause, Dr. Archer and his collaborators divided participants into 33 individuals who were 1 or 2 years post menopause, 86 women who were 3-5 years post menopause, and 521 women who had experienced menopause at least 6 years before study baseline.
In this analysis, 22 of the earliest postmenopause women received prasterone, seeing a 1.59 point drop in dyspareunia severity. For the 59 women in the prasterone study arms who were 3-5 year past menopause, the decrease from baseline was 0.59 points. Finally, among the 325 women who received prasterone and experienced menopause 6 or more years ago, the decrease was 0.27 points.
Although there was a numeric difference in the change in dyspareunia score severity among these groups, the differences were not statistically significant, said Dr. Archer. Again, though, those who took prasterone had a significant reduction in dyspareunia severity scores when compared with those taking placebo (P less than .0001, P = .0136, and P = .0024, respectively).
In the prasterone study arms, 184 had previously used hormone therapy, and 222 had not. After 12 weeks of intravaginal prasterone, there was no statistically significant difference between the two subgroups, with a decreases in dyspareunia severity scores of 0.45 and 0.32, respectively. The decreases in severity scores when compared with those among women who took placebo were again statistically significant for both subgroups, however (P = .0002 and P = .0057, respectively).

Sexual assault and harassment linked to hypertension, depression, and anxiety
Sexual harassment and assault may have significant health impacts on women in midlife, including greater risk of hypertension, poor sleep, depression, and anxiety, research suggests.
In the Oct. 3 online edition of JAMA Internal Medicine, a study of 304 women aged 40-60 years showed that 19% reported a history of workplace sexual harassment, 22% reported a history of sexual assault, and 10% reported both. The report was presented simultaneously at the North American Menopause Society annual meeting in San Diego.
The researchers found that those with a history of sexual assault had an almost threefold higher odds of clinically elevated depressive symptoms (OR, 2.86, P = .003), and more than twofold greater odds of anxiety and poor sleep (OR, 2.26, P = .006 and OR, 2.15, P = .007 respectively).
Women who reported experiencing sexual harassment in the workplace – and who were not taking antihypertensive medication – were more than twice as likely to have stage 1 or 2 hypertension, compared with women who had not experienced sexual harassment (OR, 2.36, P = .03). They also had 89% higher odds of poor sleep consistent with clinical insomnia (P = .03).
These associations all persisted even after adjustment for demographic and biomedical factors such as age, ethnicity, body mass index, snoring, and the use of antihypertensive, antidepressant, and anti-anxiety medications.
“Given the high prevalence of sexual harassment and assault, addressing these prevalent and potent social exposures may be critical to promoting health and preventing disease in women,” wrote Rebecca C. Thurston, PhD, of the department of psychiatry at the University of Pittsburgh, and her coauthors.
They noted that the 1-in-5 rate of sexual harassment or assault seen in the study was actually lower than that seen in national samples, which may be have been because of the exclusion of women who smoked, had undergone hysterectomies, or were using common antidepressants or cardiovascular medications.
“Few characteristics distinguished between women who had been sexually harassed and those who had been sexually assaulted, with the exception that women who were sexually harassed were more highly educated yet more financially strained,” they wrote. “Notably, women who are younger or are in more precarious employment situations are more likely to be harassed, and financially stressed women can lack the financial security to leave abusive work situations.”
The study was supported by the National Institutes of Health, National Heart Lung and Blood Institute, and the University of Pittsburgh Clinical and Translational Science Institute. Dr. Thurston declared consultancies for MAS Innovations, Procter & Gamble, and Pfizer, but no other conflicts of interest were declared.
