Response: Reports of premature menopause after human papillomavirus (HPV) vaccination have received a lot of media attention, including on social media, but these reports were based on a small number of isolated cases. Large studies have demonstrated the safety of HPV vaccination, but parental safety concerns—including potential impact on future fertility—are often cited as one reason for lower HPV coverage.

Rates of HPV vaccination have lagged behind coverage rates for other recommended adolescent vaccinations, such as tetanus-diphtheria-acellular pertussis and meningococcal conjugate. (Based on national coverage estimates from 2016, 65% of 13–17 year-old females received at least one HPV vaccination and only 49.5% were up to date with the series, compared to about 88% of adolescents who received Tdap.)

We conducted a study of nearly 200,000 young women to determine whether there was any elevated risk of primary ovarian insufficiency (POI) after HPV or other recommended vaccinations.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The background for this study is based on the current measurements used to determine cardiovascular disease risk in postmenopausal women. Higher levels of HDL “good cholesterol” as measured by the widely available clinical test, HDL-Cholesterol, may not always be indicative of a lower risk of cardiovascular disease in postmenopausal women.

HDL is a family of particles found in the blood that vary in sizes, cholesterol contents and function. HDL particles can become dysfunctional under certain conditions such as chronic inflammation. HDL has traditionally been measured as the total cholesterol carried by the HDL particles, known as HDL cholesterol. HDL cholesterol, however, does not necessarily reflect the overall concentration, the uneven distribution, or the content and function of HDL particles.

We looked at 1,138 women aged 45 through 84 enrolled across the U.S. in the Multi-Ethnic Study of Atherosclerosis (MESA), a medical research study sponsored by the National Heart, Lung and Blood Institute of the National Institutes of Health (NIH). MESA began in 1999 and is still following participants today. We assessed two specific measurements of HDL: the number and size of the HDL particles and total cholesterol carried by HDL particles. Our study also looked at how age when women transitioned into post menopause, and the amount of time since transitioning, may impact the expected cardio-protective associations of HDL measures.

Our study points out that the traditional measure of the good cholesterol, HDL cholesterol, fails to portray an accurate depiction of heart disease risk for postmenopausal women. We reported a harmful association between higher HDL cholesterol and atherosclerosis risk that was most evident in women with older age at menopause and who were greater than, or equal to, 10 years into post menopause. In contrast to HDL cholesterol, a higher concentration of total HDL particles was associated with lower risk of atherosclerosis. Additionally, having a high number of small HDL particles was found beneficial for postmenopausal women. These findings persist irrespective of age and how long it has been since women became postmenopausal.

On the other hand, large HDL particles are linked to an increased risk of cardiovascular disease close to menopause. Women are subject to a variety of physiological changes in their sex hormones, lipids, body fat deposition and vascular health as they transition through menopause. We are hypothesizing that the decrease of estrogen, a cardio-protective sex hormone, along with other metabolic changes, can trigger chronic inflammation over time, which may alter the quality of HDL particles. Future studies should test this hypothesis.

The study findings indicate that measuring size and number of HDL particles can better reflect the well-known cardio-protective features of the good cholesterol in postmenopausal women. Continue reading

Perimenopause: Oral Micronized Progesterone May Reduce Hot Flashes, Night Sweats and Sleep Problems

Dr. Prior has written the second edition of the award-winning book, Estrogen’s Storm Season—Stories of Perimenopause this year as an ebook on Google Play.


MedicalResearch.com: What is the background for this study?

Response: There is an urgent need for an effective therapy for perimenopausal hot flushes/flashes and night sweats (vasomotor symptoms, VMS). Although often considered “estrogen deficiency symptoms” VMS are common and very problematic for women in the menopause transition and who have not yet been one year without flow. About 23% of North American women are now in the perimenopausal age range. Surprisingly VMS are more common in perimenopause than in menopause; 9% of perimenopausal women have severe VMS as classified by the FDA, meaning more than 50 VMS per week of moderate to intense severity.

The commonly used therapies for VMS in midlife women have not been proven more effective than placebo! That includes combined hormonal contraceptives (CHC) and menopausal-type hormone therapy (MHT) as well as the SSRI/SNRI anti-depressants and gabapentin.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In this study we compared two commonly recommended treatments for menopausal vaginal discomfort – low dose vaginal estradiol tablets and a vaginal moisturizer – to placebo, and found no difference in reduction of symptom severity; all three groups improved over 12 weeks of treatment.  This is great news for women, as it means that using any treatment regularly is likely to have benefit, whether it costs $20 or $200.

Symptoms of vaginal dryness, irritation and pain with sex, which occur in over half of postmenopausal women, cause a significant decrease in quality of life and negatively impact intimate relationships.  The significant impact of these symptoms is reflected in the fact that we enrolled all 302 participants in under a year, a faster enrollment than any of the four prior trials  conducted by the MsFlash research network that evaluated treatments for hot flashes.  Women were desperate for some kind of intervention for these symptoms.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The effect of menopausal hormone therapy (MHT), previously known as hormone replacement therapy, on cardiovascular health in post-menopausal women remains controversial and unclear. Extensive observational data had suggested MHT to be cardioprotective, leading to MHT being routinely prescribed for both primary and secondary prevention of coronary heart disease (CHD). However, subsequent data from the Women’s Health Initiative (WHI) and Heart and Estrogen/Progestin Replacement Study (HERS) studies cast doubt on the beneficial cardiovascular effects of MHT; this was reflected in learned societies’ clinical guidance concerning MHT’s role in CHD prevention. The most recent randomised trial data on the subject arose from the Danish Osteoporosis Prevention Study, which indicated that women taking menopausal hormone therapy had a reduced risk of the composite endpoint of mortality, heart failure and myocardial infarction but the study has been subject to criticism [10]. In more recent work, again from the WHI, there was no difference in cardiovascular mortality in MHT users compared to placebo, although the authors themselves state that cause-specific mortality data should be interpreted “cautiously”.

The UK Biobank is an ongoing, large-scale, population-based study designed to examine determinants of health in middle and old age. Besides extensive collection of health questionnaire data, biological samples and physical measurements, it has incorporated cardiovascular magnetic resonance (CMR) imaging – the gold standard for analysis of cardiac structure and function – to provide detailed imaging phenotypes. At present, there is a paucity of data on the effects of  menopausal hormone therapy on left ventricular (LV) and left atrial (LA) volumes and function, alterations in which are markers of subclinical cardiovascular disease and have prognostic implications.

We found that in a large, population-based cohort of post-menopausal women free of cardiovascular disease, use of menopausal hormone therapy is not associated with adverse, subclinical changes in cardiac structure and function.

Indeed, we demonstrate significantly smaller LV and LA chamber volumes which have been linked to favorable cardiovascular outcomes in other settings.

 MedicalResearch.com: What is the background for this study? What are the main findings?

Response: USPSTF recommendations are based off several studies, but is mainly based off of the Women’s Health Initiative.

The Women’s Health Initiative was a 15 year prevention study with a focus on death, disability and impaired quality of life in postmenopausal women. This study was originally performed in 1991.

The USPSTF reevaluated the data along with several other studies to assess the role of hormone replacement therapy in prevention of chronic diseases such as heart disease, stroke, blood clot, gallbladder disease, dementia.  The USPSTF has found that hormone replacement therapy has some benefit in reducing the risk of fractures, and, potentially, diabetes.  The USPSTF has found that hormone replacement therapy can increase the risk of coronary artery disease, stroke, blood clot, gall bladder disease, urinary incontinence and dementia.

With these risks, the USPSTF states that hormone replacement therapy should not be used as a preventative medicine, but, rather, used for treatment of symptomatic menopause and not prevention of osteoporosis or heart disease.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The Data Registry on Experiences of Aging, Menopause and Sexuality (DREAMS) was used for this study investigating the association between vasomotor symptoms (hot flashes and night sweats) and risk for obstructive sleep apnea, a common and underdiagnosed sleep disorder in women which is associated with increased cardiovascular risk.

We found that Women who had severe or very severe hot flashes or night sweats were more likely to be at increased risk for obstructive sleep apnea.  This association held even after adjusting for age, body mass index, smoking and hypertension, such that the odds of women having intermediate /high risk for obstructive sleep apnea were 1.87 times higher for those with severe/very severe hot flashes/night sweats compared to those with less severe symptoms.  We decided to analyze the group of women with normal body mass index, and indeed, this finding was still significant in the lean group of women.

Hormones Affect Carotid Plaque Stability and Stroke Vulnerability

MedicalResearch.com Interview with:

Marija Glisic Epidemiology, Erasmus MC

Marija Glisic

Marija Glisic
Epidemiology, Erasmus MC 

MedicalResearch.com: What is the background for this study?

Response: Carotid atherosclerosis is one of most important risk factors for developing stroke. Carotid atherosclerotic plaques characterized by lipid core presence and intraplaque haemorrhage are considered to be unstable, and therefore more prone to rupture and lead to consequent stroke. Sex differences have been observed in carotid plaque composition as well as in stroke incidence. Sex hormones, particularly estrogen and testosterone actions are suggested to underlie the observed sex differences in atherosclerosis. Experimental evidence suggests a direct action of estradiol and testosterone on the vascular system, affecting various mechanisms that may impact plaque composition and subsequently stroke risk.

MedicalResearch.com: What is the background for this study?

Response: Cataracts are a leading cause of vision loss worldwide, and cataract surgery is an intervention that is known to be extremely effective to address the vision loss related to cataract. However, it is unclear if there are benefits of cataract surgery beyond vision improvement in people with cataracts. Previous studies have suggested that in addition to improving vision, cataract surgery may decrease the risk of fractures and accidents, improve mental health, and improve overall quality of life. The purpose of the present study was to further investigate the potential benefits of cataract surgery and to determine if cataract surgery was associated with increased survival in people with cataracts.

MedicalResearch.com: What is the background for this study?

Response: The current report provides new information on total mortality and the rates of death from specific causes (cardiovascular disease, cancer, other major illnesses) over 18 years of follow-up in the Women’s Health Initiative (WHI) randomized trials of hormone therapy (estrogen + progestin and estrogen alone). This is the first WHI report to focus on all-cause and cause-specific mortality. It includes all of the 27,347 women in the 2 hormone therapy trials with >98% follow-up over 18 years, during which time 7,489 deaths occurred. This is more than twice as many deaths as were included in earlier reports. The report also provides detailed information on differences in results by age group (ages 50-59, 60-69, 70-79) at time of study enrollment.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Heart fat is associated with greater coronary heart disease risk. Postmenopausal women have greater heart fat volumes than premenopausal women, and the association between specific heart fat depots and calcification in the coronary arteries is more pronounced after menopause. Race, central adiposity, and visceral adiposity are important factors that could impact heart fat volumes.

We evaluated whether racial differences in heart fat volumes and in their associations with central (abdominal visceral fat) and general adiposity (as measured by body mass index [BMI]) exist in midlife women. Our study included 524 women from the Study of Women’s Health Across the Nation (SWAN) (mean age: 51 years; 62% White and 38% Black) who had data on heart fat volumes, abdominal visceral fat and BMI.

After accounting for the potential health effects of lifestyle and socioeconomic factors we found that midlife Black women had less heart fat volumes than white women and not surprisingly, the more fat a women carries overall, the higher her risk for a fatty heart. However, white women with higher BMI had significantly more heart fat, as measured by a CT scan, than black women with the same BMI. For black women, the levels of heart fat were greater if they carried more fat in their midsection, as measured by a cross-sectional CT scan, compared with white women with the same volume of fat in their midsection. The results echo the findings we have reported previously in midlife men and published at the International Journal of Obesity (2015) 39, 488–494.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There has been a growing interest in the role of periodontal disease in system chronic diseases, including cancer. We explored the association of periodontal disease history and incident cancer in the women’s health initiative study of postmenopausal women. We found that women reporting periodontal disease history were at increased risk of developing cancer overall. In addition they were found to have significant increased risk of specific cancers including cancers of the lung, breast, esophagus, gallbladder and melanoma. The risk persisted after control for many other factors. In addition, the risk was seen in women regardless of their smoking history. Both ever smokers and never smokers were found to have increased risk of cancer associated with periodontal disease history.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is known that women with early onset of menopause (age below 45 years) have an increased risk of cardiovascular disease and overall mortality. This increased risk is thought to be due to the adverse effects of menopause on cardiovascular risk factors.

Type 2 diabetes is a major risk factor for cardiovascular disease, but it remains unclear whether age at menopause affects the risk of developing type 2 diabetes. Our study shows that women who experience menopause before the age of 40 were almost 4 times more likely to develop type 2 diabetes than those experiencing menopause after 55 years old. Moreover, those who had menopause between 40 to 44 years were 2.4 times more likely to have diabetes later in life. The risk of having diabetes reduced by 4 % per year older the women experienced menopause. Adjustment for the various confounding factors and differences in genetic predisposition to early menopause did not affect the results.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Hearing loss affects approximately 48 million Americans and the number is expected to increase as the population ages. Some previous studies suggested that menopause may increase the risk for hearing loss, presumably due to the reduction in circulating estrogen levels, and that postmenopausal hormone therapy might slow hearing decline by “replacing” estrogen. To evaluate the role of menopause and postmenopausal hormone therapy as risk factors for hearing loss, we examined the independent associations between menopausal status, oral hormone therapy, and risk of self-reported hearing loss in 80,972 women who are participants in the Nurses’ Health Study II, aged 27-44 years at baseline, and were followed from 1991 to 2013.

After more than 1.4 million person-years of follow-up, 18,558 cases of hearing loss were reported (~23% of the women developed hearing loss). We did not observe an overall independent association between menopausal status and risk of hearing loss.

However, the risk among women who underwent natural menopause at an older age was higher. Specifically, the risk among women who underwent natural menopause at age 50 or older was 10% higher than among those who underwent natural menopause before age 50 [multivariable-adjusted relative risk (MVRR): 1.10, 95% CI 1.03, 1.17]. When we conducted an analysis restricted to women who underwent natural menopause and did not use hormone therapy (HT), the multivariable-adjusted relative risk among women who underwent natural menopause at age 50-54 years was 21% higher (MVRR: 1.12, 95% CI: 1.10, 1.34), and among women who underwent natural menopause at age 55+ years was 29% higher (MVRR: 1.29, 95% CI: 1.11, 1.50), compared with women who underwent natural menopause before age 50.

Among postmenopausal women, we also found that use of oral HT was associated with higher risk of hearing loss, and the magnitude of the risk tended to increase with longer duration of use (p-trend < 0.001). Compared with women who never used any type of HT, the MVRR of hearing loss among women who used oral HT for 5-9.9 years was 15% higher (MVRR: 1.15, 95% CI: 1.06, 1.24), and for 10+ years was 21% higher (MVRR: 1.21, 95% CI: 1.07, 1.37). When specific types of oral HT were examined, longer duration of use of either oral estrogen-only or of combined estrogen plus progestogen HT were each associated with higher risk. Fewer women reported use of progestogen-only oral HT, yet among these women a higher risk was suggested, but not significant (MVRR: 1.15, 95% CI: 0.98, 1.35). Transdermal HT use was less common, but the associations observed were similar to those with oral hormone therapy. When examined separately by type of menopause, the results for HT use were similar.

MedicalResearch.com: What is the background for this study?

Response: The Phase 2b uterine fibroids study was a 24-week, multicenter, double-blind, randomized, placebo-controlled, parallel group clinical trial that evaluated the efficacy and safety of elagolix alone or in combination with add-back therapy (estradiol/norethindrone acetate) in women with heavy uterine bleeding associated with uterine fibroids. Elagolix is currently being investigated in diseases that are mediated by sex hormones, such as uterine fibroids and endometriosis.

The study was conducted in 567 premenopausal women, age 18 to 51, at 100 sites in the United States, Canada, Puerto Rico, Chile and the United Kingdom. The two cohort design study evaluated the safety and efficacy of two elagolix treatment regimens (300mg BID and 600mg QD) alone and in combination with two different strengths of add-back therapy (estradiol/norethindrone acetate). The data presented were results from the 300mg cohort. Results from the 600mg cohort were similar and will be reported in a future publication.

Current non-surgical treatments indicated for uterine fibroids are limited, and women suffering from heavy menstrual bleeding associated with uterine fibroids need more options.

MedicalResearch.com: What is the background for this study?

Response: Physical activity improves health and may delay the onset of chronic diseases. For women in particular, the rate of some chronic diseases accelerates at middle age around the time of menopause; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population.

The main aim of this study was to characterize the level of physical activity and to examine the association between different female reproductive factors and objectively-measured physical activity in middle-aged women. The reproductive factors included cumulative reproductive history index, and perceived menopausal and pelvic floor dysfunction symptoms.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Our study revealed a previously unknown, menopause-specific indicator of heart disease risk. For the first time, we’ve pinpointed the type of heart fat, linked it to a risk factor for heart disease and shown that menopausal status and estrogen levels are critical modifying factors of its associated risk in women.

My team evaluated clinical data, including blood samples and heart CT scans, on 478 women from Pittsburgh and Chicago enrolled in the Study of Women’s Health Across the Nation (SWAN). The women were in varying stages of menopause, averaged 51 years old and were not on hormone replacement therapy.

In a previous study, we showed that a greater volume of paracardial fat, but not epicardial fat, after menopause is associated with a decline in the sex hormone estradiol—the most potent estrogen—in women. The higher volume of epicardial fat was tied to other risk factors, such as obesity.

In the new study, we built on those findings to discover that not only is a greater paracardial fat volume specific to menopause, but—in postmenopausal women and women with lower levels of estradiol—it’s also associated with a greater risk of coronary artery calcification, an early sign of heart disease that is measured with a heart CT scan.

MedicalResearch.com: What is the background for this study?

Response: Weight cycling has been studied as a possible risk factors for all-cause mortality and was found to be insignificant in some studies and significant in other studies when adjusted to age and timing of when the weight cycling occurred. It was proposed that weight cycling may increase risk of chronic inflammation by which weight cycling was considered to be a risk factor for increased morbidity and all cause mortalities. Other studies have reported that frequent weight cycling was associated with shorter telomere length, which is a risk factor for several comorbidities including CHD. Earlier studies showed that weight cycling has an association with increase in size of adipocytes as well as fluctuation of serum cholesterol, triglycerides, glucose, insulin, and glucagon which may contribute to the increased incidence of diabetes. Alternatively, in the nurses’ health study , weight cycling was not predictive of cardiovascular or total mortality.

MedicalResearch.com: What is the background for this study?

Response: This study was mainly motivated by the absence of available data on the effect of menopausal hormone therapy (MHT) on bone microarchitecture, as well as contradictory results of previous trials regarding the persistence of a residual effect after MHT withdrawal.

We performed a cross-sectional analysis of 1279 postmenopausal women aged 50-80 years participating in OsteoLaus cohort of Lausanne University Hospital. Participants had bone mineral density (BMD) measurement by dual X-ray absorptiometry (DXA) at lumbar spine, femoral neck and total hip, as well as assessment of trabecular bone score (TBS), a textural index that evaluates pixel grey-level variations in the lumbar spine DXA image, providing an indirect index of trabecular microarchitecture.

Jill M. Goldstein, Ph.D.

Director of Research for the Connors Center for Women’s Health and Gender Biology
Brigham and Women’s Hospital and
Professor of Psychiatry and Medicine at Harvard Medical School

MedicalResearch.com: What is the background for this study?

Response: Maintaining intact memory function as we age is one of the primary public health challenges of our time. In fact, women are at almost twice the risk for Alzheimer’s disease and it is not only because women live longer. Thus, it is incumbent upon us to understand this sex difference and incorporate the knowledge into the development of sex-dependent therapeutics.

Our study focused on beginning this investigation by understanding how memory circuitry and memory function change over the menopausal transition, when we believe that sex differences in memory aging emerge. By understanding healthy aging, we will better understand how the brain goes awry with age differently in men and women and who might be at highest risk for Alzheimer’s disease later in life.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Scientists have suspected that genes may contribute to the risk of getting hot flashes and night sweats, but studies so far have been few in number and only focused on small parts of the human gene code (for example, the gene coding for estrogen receptors). No study has ever comprehensively sampled gene variations that span the entire human genome to look for associations between genetic variation and risk of hot flashes and night sweats.

This was the first study of its kind, performed in more than 17.000 postmenopausal women participating in the Women’s Health Initiative Study. We examined 11,078,977 single-nucleotide polymorphisms, or SNPs, which are gene variants, in a genome-wide association study.

Our main results were that 14 gene variants (SNPs) that were significantly associated with increased risk of having hot flashes. All of these variants were located in chromosome 4, in the gene that codes for the tachykinin receptor 3.

MedicalResearch.com: What is the background for this study?

Response: We conducted this study to advance our understanding about causes of mood disturbance in the menopause transition that are specifically related to menopause. We used an experimental model to dissect out the contributions of hot flashes and sleep disturbance from contribution of changing levels of estrogen because hot flashes, sleep problems, and estrogen fluctuations co-occur and are difficult to distinguish from one another. Understanding whether hot flashes and/or sleep disturbance are causally related to mood disturbance will help us identify who is at risk for mood changes during the menopause transition. This is incredibly important now that we are finding effective non-hormonal treatments for hot flashes and sleep disruption.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Menopause marks a major life transition for women, resulting in the loss of ovarian follicle development. Although menopause is a universal phenomenon among women, the timing of the final menstrual period differ greatly between women, and is considered a marker of aging. By quantifying data of nearly 310,329 non-overlapping women, we found that women who experienced an early menopause (i.e. younger than 45 years) have an excess risk of CHD, CVD-mortality and all-cause mortality. Furthermore, being 45-49 years at menopause compared to ≥50 years was associated with increased risk of carotid atherosclerosis.
