Symptoms of menopause - global prevalence, physiology and implications

Alisol B 23-acetate activates ABCG5/G8 in the jejunum via the LXRα/ACAT2 pathway to relieve atherosclerosis in ovariectomized ApoE-/- mice

Phytosterols have been shown to improve blood lipid levels and treat atherosclerosis. This research investigated the effects of phytosterol Alisol B 23-acetate (AB23A) on jejunum lipid metabolism and atherosclerosis. The results show that intragastric administration of AB23A can significantly reduce atherosclerotic plaque area and lipid accumulation in the jejunum of ovariectomized ApoE-/- mice fed a high-fat diet and can also improve the lipid mass spectra of the plasma and jejunum. In vitro studies have shown that AB23A can increase cholesterol outflow in Caco-2 cells exposed to high fat concentrations and increase the expression of ATP-binding cassette transfer proteins G5/G8 (ABCG5/G8), the liver X receptor α (LXRα). Furthermore, inhibition of LXRα can significantly eliminate the active effect of AB23A on decreasing intracellular lipid accumulation. We also confirmed that AB23A has a negative effect on Acyl-CoA cholesterol acyltransferase 2 (ACAT2) in Caco-2 cells cultured in the high concentrations of fat, and we found that AB23A further reduces ACAT2 expression in cells treated with the ACAT2 inhibitor pyripyropene or transfected with ACAT2 siRNA. In conclusion, we confirmed that AB23A can reduce the absorption of dietary lipids in the jejunum by affecting the LXRα-ACAT2-ABCG5/G8 pathway and ultimately exert an anti-atherosclerotic effect.

Menopausal Symptoms and Associated Social and Environmental Factors in Midlife Chinese Women

Objective

To investigate the dependency of menopausal symptoms on age and/or menopausal status and association with social and environmental factors.

Methods

The cross-sectional study was conducted on 4595 women (40–83 years) coming from 31 provinces during two years to our “Menopause Clinic”, the first official center in China. Menopausal symptoms were assessed: negative mood, cognitive symptoms, sleep disorder, vasomotor symptoms (VMS), urogenital symptoms, autonomic nervous disorder, limb pain/paresthesia. Social and environmental factors were collected; simple and unconditional logistic regression with adjustments by all analyzed factors were used to assess associations.

Results

Urogenital symptoms were the most common and VMS the least common complaints. All symptoms, except cognitive and urogenital symptoms, worsened age-dependently up to 60 years but improved beyond this age. Most symptoms also were associated with menopause, except negative mood and autonomic nervous disorders. Soya-rich diet decreased all symptoms, but only if consumed daily. Exercise was beneficial for some symptoms. Hormone replacement therapy (HRT) was most effective but only with regular use. Increased alcohol consumption aggravated VMS. Higher education was associated with less symptoms; no relationship was found for smoking, gravidity, parity, and menarche.

Conclusion

All symptoms, except cognitive and urogenital symptoms, worsened age-dependently up to 60 years but improved beyond this age; most were also associated with menopause. For the first time in a large study population, it was observed that soy-rich diet is protective but only with daily consumption. Exercising can protect against some of the symptoms. HRT decreased all symptoms, but regular use is necessary. Women with higher education reported less symptoms, but after adjustments no other relationships were observed (ChiCTR2000035047).

The evolutionary ecology of age at natural menopause: implications for public health

Evolutionary perspectives on menopause have focused on explaining why early reproductive cessation in females has emerged and why it is rare throughout the animal kingdom, but less attention has been given to exploring patterns of diversity in age at natural menopause. In this paper, we aim to generate new hypotheses for understanding human patterns of diversity in this trait, defined as age at final menstrual period. To do so, we develop a multilevel, interdisciplinary framework, combining proximate, physiological understandings of ovarian ageing with ultimate, evolutionary perspectives on ageing. We begin by reviewing known patterns of diversity in age at natural menopause in humans, and highlight issues in how menopause is currently defined and measured. Second, we consider together ultimate explanations of menopause timing and proximate understandings of ovarian ageing. We find that ovarian ageing is highly constrained by ageing of the follicle - the somatic structure containing the oocyte - suggesting that menopause timing might be best understood as a by-product of ageing rather than a facultative adaptation. Third, we investigate whether the determinants of somatic senescence also underpin menopause timing. We show that diversity in age at menopause can be, at least partly, explained by the genetic, ecological and life-history determinants of somatic ageing. The public health implications of rethinking menopause as the by-product rather than the catalyst of biological ageing are discussed.

Uterine fibroids in menopause and perimenopause

Uterine fibroids (UFs) are benign tumors that arise from a single genetically altered mesenchymal stem cell under the influence of gonadal hormones. UFs are the most common benign gynecologic tumors in premenopausal women worldwide. It is estimated that nearly 70% to 80% of women will develop UFs at some point during their lifetime. UFs often present with abnormal uterine bleeding (AUB), pelvic fullness, and may have deleterious effects on fertility. The natural regression of UFs begins in menopause. This is, however, a generality as this pathology may still be present in this age group. Many clinicians are concerned about hormone therapy (HT) because of UFs regrowth; nevertheless, research of this subject remains inconclusive. If UFs are present in perimenopause or menopause, they typically manifest as AUB, which represents up to 70% of all gynecological consultations in perimenopausal and postmenopausal women. As AUB is a broad symptom and may not be specific to UFs, a thorough evaluation is required for correct diagnosis and proper treatment accordingly. Understanding the unique characteristics of the available treatment modalities is crucial in deciding the appropriate treatment approach. Decision on treatment modality should be made based on selection of the least morbidity and lowest risk for each patient. Multiple modalities are available; however, surgery remains the method of choice, with the best cure rates. Various attempts to create an inexpensive, safe, and effective drug for the treatments of UFs are still in the early stages of the clinical trials with some showing great promise. Treatment options include tibolone, aromatase inhibitors, selective estrogen receptor modulators, uterine artery embolization, and selective progesterone receptor modulators.

Asparagus cochinchinensis extract ameliorates menopausal depression in ovariectomized rats under chronic unpredictable mild stress

BACKGROUND

Depression is a serious and common psychiatric disorder generally affecting more women than men. A woman's risk of developing depression increases steadily with age, and higher incidence is associated with the onset of menopause. Here we evaluated the antidepressant properties of Asparagus cochinchinensis (AC) extract and investigated its underlying mechanisms in a rat menopausal depression model.

METHODS

To model this menopausal depression, we induced a menopause-like state in rats via ovariectomy and exposed them to chronic unpredictable mild stress (CUMS) for 6 weeks, which promotes the development of depression-like symptoms. During the final 4 weeks of CUMS, rats were treated with either AC extract (1000 or 2000 mg/kg, PO), which has been reported to provide antidepressant effects, or with the tricyclic antidepressant imipramine (10 mg/kg, IP).

RESULTS

We report that CUMS promotes depression-like behavior and significantly increases serum corticosterone and inflammatory cytokine levels in the serum of ovariectomized (OVX) rats. We also found that CUMS decreases the expression of brain-derived neurotrophic factor (BDNF) and its primary receptor, tropomyosin receptor kinase B (TrkB), in OVX rats, and treatment with AC extract rescues both BDNF and TrkB expression levels.

CONCLUSION

These results suggest that AC extract exerts antidepressant effects, possibly via modulation of the BDNF-TrkB pathway, in a rat model of menopausal depression.

The associations of childhood adiposity with menopausal symptoms in women aged 45-49 years: An Australian Cohort Study

OBJECTIVES

To examine the associations of childhood adiposity with menopausal symptoms in women aged 45-49 years.

STUDY DESIGN

National population-based cohort study of 334 girls prospectively followed from childhood (aged 11-15) through to midlife (aged 45-49). Childhood overweight and obesity were defined by international age- and sex-specific standards for body mass index (BMI), and abdominal obesity was defined as waist/height ratio≥0.5.

MAIN OUTCOME MEASURES

Vasomotor symptoms (VMS), vaginal dryness, total menopausal symptoms and domain-specific symptoms (somatic, psychological and urogenital) were measured during 2018-19 using the Menopause Rating Scale (MRS) and classified as none, mild, moderate or severe.

RESULTS

The prevalence of mild, moderate and severe VMS was 24.0 %, 9.0 % and 3.9 %, and of vaginal dryness was 12.6 %, 4.8 % and 2.4 %. No significant associations of childhood overweight/obesity or abdominal obesity with VMS or vaginal dryness were found after adjustment for childhood age, follow-up length, smoking, socioeconomic status and diet quality. Childhood overweight/obesity was associated with increased risks of more severe total (RR:1.17, 95 % CI:1.02-1.36), psychological (RR:1.19, 95 % CI:1.04-1.35) and urogenital (RR:1.29, 95 % CI:1.14-1.46) symptoms measured using the MRS. Associations with childhood abdominal obesity were mostly stronger with more severe total (RR:2.19, 95 % CI:1.48-3.23), somatic (RR:1.52, 95 % CI:1.15-2.02), psychological (RR:1.21, 95 % CI:1.04-1.42) and urogenital (RR:2.11, 95 % CI:1.39-3.20) symptoms.

CONCLUSIONS

Childhood adiposity was not associated with increased risks of more severe VMS or vaginal dryness in women aged 45-49 years. Childhood adiposity, especially abdominal obesity, was associated with more severe total, somatic, psychological and urogenital symptoms. However, the association between these symptoms and menopause is not established.

Management of urinary incontinence in postmenopausal women: An EMAS clinical guide

INTRODUCTION

The prevalence of urinary incontinence and of other lower urinary tract symptoms increases after the menopause and affects between 38 % and 55 % of women aged over 60 years. While urinary incontinence has a profound impact on quality of life, few affected women seek care.

AIM

The aim of this clinical guide is to provide an evidence-based approach to the management of urinary incontinence in postmenopausal women.

MATERIALS AND METHODS

Literature review and consensus of expert opinion.

SUMMARY RECOMMENDATIONS

Healthcare professionals should consider urinary incontinence a clinical priority and develop appropriate diagnostic skills. They should be able to identify and manage any relevant modifiable factors that could alleviate the condition. A wide range of treatment options is available. First-line management includes lifestyle and behavioral modification, pelvic floor exercises and bladder training. Estrogens and other pharmacological interventions are helpful in the treatment of urgency incontinence that does not respond to conservative measures. Third-line therapies (e.g. sacral neuromodulation, intravesical onabotulinum toxin-A injections and posterior tibial nerve stimulation) are useful in selected patients with refractory urge incontinence. Surgery should be considered in postmenopausal women with stress incontinence. Midurethral slings, including retropubic and transobturator approaches, are safe and effective and should be offered.

Knowledge and awareness toward menopause and hormone therapy among premenopausal women in Jordan

BACKGROUND

Menopause is a natural important transition in women's life. Having adequate knowledge and perception about menopause at a young age is critical for women to cope better with its associated consequences and improve their well-being.

OBJECTIVE

This study evaluated the awareness, knowledge, and perception of menopause and menopause hormone therapy (MHT) among premenopausal females from Jordan.

METHODS

A cross-sectional study including females aged 20-40 years (n = 450) was conducted from November 2018 to March 2019 in two hospitals in Irbid, Jordan. A structured questionnaire was developed based on previous literature and using the Green Climacteric Scale to assess participants' knowledge and awareness of signs and symptoms of menopause and MHT. Data were collected by face-to-face interview. Factors associated with the degree of menopausal knowledge were identified.

RESULTS

The mean ± standard deviation age of participants was 29.1 ± 6.3 years. More than half of participants were knowledgeable about several aspects of menopause. Education to college or more was significantly and positively associated with knowledge about menopause (β = 0.504, p = 0.005). The majority of participants did not know the roles, benefits, and risks of MHT. There was an almost equal distribution for participants' positive (47.6%) and negative (50%) attitudes toward menopause.

CONCLUSIONS

The findings suggest that premenopausal females in Jordan are knowledgeable about various aspects of menopause. Nevertheless, there is still a need to develop educational programs and implement proper counseling to improve young females' awareness about menopause, particularly its health implications and treatment options.

The influence of phytoestrogens on different physiological and pathological processes: An overview

Functional foods have nutritional properties and organic functions, which are beneficial to health. Certain types of functional food components are so-called phytoestrogens, non-steroidal compounds derived from the metabolism of precursors contained in plants, which originate secondary metabotypes known to induce biological responses and by mimicry or modulating the action of endogenous estrogen. These molecules are involved in several physiological and pathological processes related to reproduction, bone remodeling, skin, cardiovascular, nervous, immune systems, and metabolism. This review aimed to present an overview of phytoestrogens regarding their chemical structure, actions, and effects in the organism given several pathologies. Several studies have demonstrated beneficial phytoestrogen actions, such as lipid profile improvement, cognitive function, menopause, oxidative stress, among others. Phytoestrogens effects are not completely elucidated, being necessary future research to understand the exact action mechanisms, whether they are via estrogen receptor or whether other hidden mechanisms produce these effects. Thus, this review makes a general approach to the phytoestrogen actions, beneficial effects, risk and limitations. However, the complexities of biological effects after ingestion of phytoestrogens and the differences in their metabolism and bioavailability indicate that interpretation of either risk or benefits needs to be made with caution.

Effect of high intensity interval training on body composition in women before and after menopause: a meta-analysis

NEW FINDINGS

What is the topic of this review? A meta-analysis of the efficacy of high intensity interval training (HIIT) in reducing weight, total fat mass (FM) and (intra)-abdominal FM in normal-weight and overweight/obese women before and after menopause. What advances does it highlight? HIIT programmes in women significantly decrease body weight and total and abdominal FM. Their effects are more evident in pre- than in postmenopausal women. Cycling HIIT seems more effective than running, especially in postmenopausal women, and training interventions longer than 8 weeks comprising three sessions a week should be promoted.

ABSTRACT

High-intensity interval training (HIIT) is a stimulating modality for reducing body weight and adipose tissue. The purpose of this meta-analysis was to assess the efficacy of HIIT in reducing weight, total fat mass (FM) and (intra)-abdominal FM in normal-weight and overweight/obese women before and after menopause. A structured electronic search was performed to find all publications relevant to our review. Stratified analyses were made of hormonal status (pre- vs. postmenopausal state), weight, HIIT modalities (cycling vs. running), programme duration (< or ≥8 weeks) and the methods used to measure body composition (dual-energy X-ray absorptiometry vs. computed tomography, Magnetic Resonance Imaging and others). A total of 38 studies involving 959 subjects were included. Our meta-analysis showed that overall HIIT programmes significantly decrease weight, total and abdominal FM in women. Both normal weight and overweight/obese women lost total FM after HIIT protocols whereas HIIT was only effective in decreasing abdominal FM in women with excess adiposity. When pre- and postmenopausal women were considered separately, the effect of HIIT on weight, total and abdominal FM were only significant before menopause. Cycling HIIT seemed more effective than running, especially in postmenopausal women, and training interventions longer than 8 weeks comprising three sessions were more efficient. HIIT is a successful strategy to lose weight and FM in normal weight and overweight/obese women. However, further studies are still needed to draw meaningful conclusions about the real effectiveness of HIIT protocols in postmenopausal women.

The Effect of Lactobacillus acidophilus YT1 (MENOLACTO) on Improving Menopausal Symptoms: A Randomized, Double-Blinded, Placebo-Controlled Clinical Trial

This study evaluated the efficacy of Lactobacillus acidophilus YT1 (MENOLACTO) for alleviating menopausal symptoms. This study was a multi-center, randomized, double-blinded, placebo-controlled clinical trial involving female subjects (ages: 40-60 years) with menopausal symptoms and a Kupperman index (KMI) score ≥ 20. Subjects were administered 1 × 108 CFU/day MENOLACTO or placebo, with the primary endpoint being total KMI score, and the effect of secondary endpoints on alleviating menopausal symptoms according to individual categories of the modified KMI, as well as a quality of life questionnaire (MENQOL questionnaire). After 12 weeks, total KMI scores decreased significantly, demonstrating improved menopausal symptoms relative to placebo along with improved modified KMI scores. Additionally, quality of life, according to the MENQOL questionnaire, significantly improved in all four symptoms-physical, psychosocial, vasomotor, and sexual symptoms. Moreover, we observed no significant difference between the two groups or significant changes in blood follicle-stimulating hormone and estradiol levels or endometrial thickness. These results demonstrated that MENOLACTO alleviated menopausal symptoms without notable side effects and improved quality of life, suggesting its efficacy as an alternative supplement to alleviate menopausal symptoms in women ineligible for hormonal therapy.

Remodeling of the soleus muscle of ovariectomized old female rats submitted to resistance training and different diet intake

Sarcopenia is a common condition that is associated mainly with hormonal factors, nutritional status, physical activity, leading to a lower quality of life. Thus, this study aimed to evaluate the effects of diets with vegetable or animal proteins (AP) associated with resistance training on the structure of the soleus muscle in aged Wistar rats. The histochemical technique was used for the typing of muscle fibers, the cross-sectional area of myocytes, and volume densities of myocytes and interstitium. Picrosirius stain was used to quantify the collagen density. Diet intake, mainly animal protein, associated with resistance training leaded to muscle remodeling, and increased deposit of collagen fibers. We observed hypertrophy in animal groups that consumed animal protein diet, even the sedentary group, although more evident in those trained.

Effects of moderate aerobic exercise on thoracic aortic remodeling of female LDL-receptor knockout ovariectomized mice

Menopause is a major factor involved in dyslipidemia increasing the risk of atherosclerosis which may be reversed by a routine of aerobic physical activity. Thus, this study aimed to analyze the effects of aerobic training on the thoracic aorta of female LDL-receptor knockout mice submitted to estrogen deprivation. Fifteen genetically modified female mice, knockout for the low-density lipoprotein receptor (LDL-Knockout group) were used as experimental groups and fifteen wild female mice (C57BL/6 J) were used as control groups. Animals were divided as (n = 5/per group): sedentary control (SC); sedentary control ovariectomized (SCO); trained control ovariectomized (TCO); LDL-Knockout sedentary (KS); LDL-Knockout sedentary ovariectomized (KOS); and LDL-Knockout trained ovariectomized (KOT). Immunohistochemical techniques for TIMP-1 and metalloproteinases 2 and 9 were used to evaluate thoracic aorta remodeling. Picrosirius stain was used to highlight the collagen fibers. Verhoff-Van Gienson was used for the quantitative analyses of elastic lamellae. Our results demonstrate a positive remodeling promoted by physical exercise in ovariectomized and dyslipidemic animals. However, further studies are needed including the evaluation of inflammatory markers present in dyslipidemia.

Longitudinal Effects of Immediate and Delayed Estradiol on Cognitive Performance in a Spatial Maze and Hippocampal Volume in Menopausal Macaques Under an Obesogenic Diet

The consumption of a diet high in fat and refined sugars has several health risks, including the development of cognitive decline and neurodegeneration. For women, menopause carries additional health risks that may interact with a high-fat diet in negative ways. Some symptoms of menopause, including cognitive impairments, can be modulated by hormone replacement therapy (HRT), but the hormonal formulation and the timing of the treatment relative to the onset of menopause are critical factors determining its efficacy. Little is known about how obesogenic, high-fat, high-sugar diets interact with HRT in menopause to affect cognition and neurodegeneration. Given the high prevalence of the consumption of an obesogenic Western-style diet, understanding how the effects of HRT are modulated by an obesogenic diet is critical for developing optimized therapeutic strategies for peri- and post-menopausal women. In this study, we investigated by magnetic resonance imaging (MRI) the effects of either immediate or delayed estradiol hormone therapy on cognition and neuroanatomy following ovo-hysterectomy (OvH) of aged, female rhesus macaques on an obesogenic diet. The macaques were followed for 2.5 years after ovo-hysterectomy, with four time points at which anatomical MRIs were acquired. Analysis of hippocampal volumes revealed an interaction between time point and treatment; hippocampal volumes in the delayed estrogen group, but not the immediate estrogen group, increased over time compared to those in untreated controls. Performance on a hippocampal-dependent spatial maze task showed improved performance in estrogen treated animals compared to OvH macaques given placebo. These results indicate that HRT may contribute to beneficial cognitive outcomes after menopause under an obesogenic diet.

Sex differences in solid pseudopapillary neoplasm of the pancreas: A population-based study

Objective

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor. This study aims to examine the clinicopathological features and surgical treatments of SPN and compare the clinical behavior and prognosis between men and women with SPN.

Methods

We collected the population data of patients with SPN diagnosed between 2004 and 2017 from the SEER database. The Kaplan‐Meier method was used to analyze overall survival (OS) and disease‐specific survival (DSS), and log‐rank tests were used to evaluate the differences between subgroups. Univariate and multivariate Cox regression analyses were performed to screen out prognostic risk factors of SPN.

Results

A total of 378 patients with SPN were included, with 246 (65.1%) female patients. 1‐, 3‐, and 5‐year overall survival rates were 98.9%, 95.7%, and 93.7%, respectively. Survival analysis revealed that regardless of stage, patients with SPN who underwent surgical interventions still had a significantly better prognosis than those without surgical interventions (P < .001). The patients with lymphatic dissection had a significantly better prognosis than those without lymphatic dissection (P < .001). Moreover, compared with female patients, male patients had significantly poorer OS and DSS (P < .001). Female SPN showed a bimodal age‐frequency distribution with early‐onset incidence at 28 years and late‐onset peak incidence at 62 years, while male SPN presented a unimodal distribution with peak incidence at approximately age 64 years. In female patients, the tumor size in premenopausal females (<65 years old) was significantly larger than that in postmenopausal females (≥65 years old) (P < .001). Clinicopathological characteristic profiles were different not only between male SPN and premenopausal female SPN but also between premenopausal and postmenopausal female SPN.

Conclusion

SPN presents indolent behavior and predominantly occurs in young women. Regardless of stage, surgical intervention is recommended. Moreover, our study is the first large enough study to demonstrate sex‐related discrepancies in SPN. Thus, different treatment strategies should be designed for patients of different sexes at different ages and hormone therapy is a promising approach for SPN.

Effect of a new herbal composition comprised of red clover and hop extract on human endothelial cell damage and vasorelaxant activity

Hormone replacement therapy may cause various side effects, including enhancing the risk of cardiovascular disease (CVD) in postmenopausal women. Here, we investigated the effect of red clover and hop extract combination (RHEC) on estrogen receptor (ER) binding and endothelial function of human umbilical vein endothelial cells (HUVECs) to develop an herbal agent for reducing the risk of CVDs. In ER competitor assay, RHEC showed binding affinity toward ERα and ERβ with IC50 values of 5.92 µg/ml and 1.66 µg/ml, respectively. In HUVECs, RHEC significantly increased the cell viability and reduced the reactive oxygen species production against oxidative stress-induced damage. We also showed that RHEC increased the NO production through upregulating the endothelial nitric oxide synthase expression via ER activation in estrogen depleted condition. In particular, RHEC showed greater efficacy with increase in NO and decrease in endothelin-1 than red clover or hop treatment alone. Additionally, 0.3-0.5 mg/ml of RHEC-induced vasorelaxation of rat aortic rings precontracted by phenylephrine. PRACTICAL APPLICATIONS: Recently, a large interest has grown in the synergistic effects of phytochemicals for better therapies to treat various diseases. Red clover and hop are well-known edible plants which are widely used to help relieve postmenopausal symptoms including CVD. However, their combination has not been studied so far. For the first time, we demonstrated that RHEC, a new herbal combination comprising the extracts from red clover and hop, appeared to be effective in protection of endothelial function against oxidative stress and estrogen depletion. Therefore, RHEC could be a potent herbal agent for reducing the risk of endothelial damage.

Healthcare Utilization and Prevalence of Symptoms in Women with Menopause: A Real-World Analysis

Objective

Self-reported studies estimated that as many as 50-75% of women experience symptoms during menopause; however, limited real-world clinical data are available to support this observation. The electronic databases of Maccabi Healthcare Services were used to describe the prevalence of menopause symptoms in Israel and to characterize patients with regard to socioeconomic status, comorbidities and use of healthcare services.

Methods

Females aged 45-54 years diagnosed with menopausal symptoms (N=17,046, cumulative incidence of 8% during the study period) were identified from the Maccabi Healthcare Services electronic database and matched to female members without menopause symptoms, one-to-one on birth year and enumeration area.

Results

Symptomatic peri- and post-menopausal women, and particularly those under 52 years, were more likely to have a higher prevalence of comorbid conditions such as depression, anxiety, osteoporosis and insomnia in the year following index. Correspondingly, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors and hypnotic drug use were significantly higher in symptomatic women as was healthcare utilization including hospitalization (OR=1.10; 95% CI=1.00-1.20), primary care visits (1.90; 1.73-2.08), gynecologist visits (24.84; 22.36-27.59) and hysterectomy procedures (2.26; 1.63-3.14).

Conclusion

Medically documented menopausal symptoms are associated with increased burden of disease (particularly among women diagnosed with menopausal symptoms prior to age 52 years), healthcare utilization and greater likelihood of undergoing hysterectomy within one year of diagnosis. This burden is expected to rise further as awareness and social acceptance of peri- and post-menopausal symptoms increase.

Factors associated with quality of life of postmenopausal women living in Iran

Background

Quality of life (QoL) after menopause could be influenced by a host of personal and social factors. This study aimed to determine the factors associated with quality of life among postmenopausal women.

Methods

This cross-sectional study was conducted among 405 postmenopausal women selected using a multi-stage randomized sampling. The data-collection tools were the WHO Quality of Life-BREF (WHOQOL-BREF), the Menopause Rating Scale (MRS), and a researcher-designed questionnaire. The relationship between QoL and its potentially correlated factors was examined using t-test, ANOVA, Pearson’s correlation, Spearman’s correlation coefficient, and multiple linear regression.

Results

A negative correlation was found between the scores of QoL (total and all subscales) and the MRS total scores. The total scores of QoL were negatively correlated with duration of menopause (r = − 0.127, P = 0.010), gravida (r = − 0.177, P < 0.001), parity (r = − 0.165, P = 0.001), frequency of stillbirth (r = − 0.104, P = 0.037), vaginal delivery (r = − 0.161, P = 0.001), and waist-to-hip ratio (r = − 0.195, P < 0.001). The QoL total scores were positively correlated with the educational level of the participants (r = 0.207, P < 0.001) and that of their spouses (r = 0.160, P = 0.001) along with their level of monthly family income (r = 0.218, P < 0.001). Multiple-linear-regression analysis showed that the total score of QoL decreased with inadequate income, waist-to-hip ratio, and the total score of MRS.

Conclusions

Personal and social factors along with the severity of menopausal symptoms affect QoL post-menopause. These factors need to have a bearing on any effort to improve QoL among postmenopausal women.

Is body image a predictor of women's depression and anxiety in postmenopausal women?

BACKGROUND

Women in perimenopausal and postmenopausal period are at increased risk of depression and anxiety. Physiologic changes in menopause can change body's appearance and function that may disturb body and then lead to anxiety and depression. This study aims to assess the relationship between body image with anxiety and depression among postmenopausal women.

METHODS

This descriptive study was performed on 307 women attending to the health centers in Tehran- Iran. Sampling was performed by a multi-staged randomized method. Data were collected by using Beck Depression questionnaire, Spielberger Anxiety Questionnaire, Fisher Body Image Questionnaire and Socio-demographic questionnaires. Data were analyzed by SPSS 21 and using t-test, Pearson and Spearman correlation tests and multiple linear regression methods.

RESULTS

The average age of the participants was 55.19 ± 4.034 years. Mean scores for body image, anxiety and depression were 163.26 ± 20.38, 12.00 ± 7.71 and 42.70 ± 8.40 respectively. Fifty five percent of women had mild to severe depression and 83.7% of them had mild to severe anxiety. Total score and all domains of body image had a negative correlation with depression and anxiety scores (P < 0.001). Multiple linear correlation showed that body image is a predictor for depression and anxiety (P < 0.001).

CONCLUSIONS

Body image of women can be effective on occurrence of depression and anxiety in menopause. Therefore, women's health policies should consider body image to control cognitive problems including depression and anxiety in menopause.

Menopause uncertainty: the impact of two educational interventions among women during menopausal transition and beyond

Introduction

Menopause is a natural part of women's lives, which is associated with physical and mental changes and can lead to uncertainty and consequent undesirable effects in the lives of menopausal women. The present study was conducted to compare the impact of multimedia and booklet educational methods on the uncertainty about menopause during this transition period.

Materials and methods

In a cluster randomized trial 68 women aged 45-55 years were randomly allocated into two groups: multimedia and booklet. Data were collected using knowledge and uncertainty questionnaires about menopause in three stages, i.e. before intervention, immediately after intervention (two weeks later), and one month later. Repeated-measures analysis of variance (rANOVA) was used to compare knowledge and uncertainty scores between two groups for the duration of the study. Data were analysed using SPSS software and p values < 0.05 were considered as statistically significant.

Results

The results of the study indicated a high level of uncertainty in both groups before the implementation of the educational program. There was no significant difference between groups in terms of knowledge and uncertainty about menopause over time (p > 0.05). However, we found a significant increase in knowledge and a significant decrease in uncertainty scores in both groups (p < 0.001) after the interventions.

Conclusions

Although the findings of this study did not show a significant difference between the effect of multimedia and booklet educational methods in postmenopausal women, the high level of uncertainty of women before intervention and its significant reduction after the implementation of the educational programs indicated the importance of education throughout this period.

Co-occurring medical conditions in adults with Down syndrome: A systematic review toward the development of health care guidelines. Part II

Adults with Down syndrome (DS) represent a unique population who are in need of clinical guidelines to address their medical care. Many of these conditions are of public health importance with the potential to develop screening recommendations to improve clinical care for this population. Our workgroup previously identified and prioritized co-occurring medical conditions in adults with DS. In this study, we again performed detailed literature searches on an additional six medical conditions of clinical importance. A series of key questions (KQ) were formulated a priori to guide the literature search strategy. Our KQs focused on disease prevalence, severity, risk-factors, methodologies for screening/evaluation, impact on morbidity, and potential costs/benefits. The available evidence was extracted, evaluated and graded on quality. The number of participants and the design of clinical studies varied by condition and were often inadequate for answering most of the KQ. Based upon our review, we provide a summary of the findings on hip dysplasia, menopause, acquired cardiac valve disease, type 2 diabetes mellitus, hematologic disorders, and dysphagia. Minimal evidence demonstrates significant gaps in our clinical knowledge that compromises clinical decision-making and management of these medically complex individuals. The creation of evidence-based clinical guidance for this population will not be possible until these gaps are addressed.

NRF2 deficiency increases obesity susceptibility in a mouse menopausal model

The risk of metabolic abnormalities in menopausal women increases significantly due to the decline in estrogen level. Nuclear factor E2-related factor 2 (NRF2) is an important oxidative stress sensor that plays regulatory role in energy metabolism. Therefore, an ovariectomized menopausal model in Nrf2-knockout (KO) mice was applied to evaluate the effect of Nrf2 deficiency on metabolism in menopausal females. The mice were divided into four groups according to their genotypes and treatments. Blood samples and bodyweights were obtained preoperatively and in the first to ninth postoperative weeks after overnight fasting. Serum levels of triglycerides (TG), total cholesterol (T-CHO), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and glucose (GLU) were measured at postoperative weeks 0, 1, 3, 5, 7, and 9. Neurotransmitter dopamine (DA) and serotonin (5-HT) was analyzed in brain tissues after sacrifice at postoperative week 9. The results demonstrated that, compared with the corresponding wild-type (WT) mice, KO ovariectomized mice had a greater bodyweight gain (P<0.01). Serum analysis showed that the serum GLU, T-CHO, and TG were significantly lower (P<0.05) but LDL was significantly higher (P<0.05) in the KO control mice than that in WT control mice. However, different from the WT counterparts, an increase in blood GLU level (P<0.05), unchanged T-CHO, TG, and HDL levels, and a significant reduction in LDL (P<0.01) was found in the KO ovariectomized mice. In addition, the level of 5-HT was significantly reduced (P<0.05) in the KO mice after ovariectomy. In conclusion, the combination of Nrf2 deletion and a decline in estrogen level induced a significant increase in bodyweight, which may be associated with their altered glucose and LDL metabolism and decreased 5-HT levels. From a clinical perspective, women with antioxidant defense deficiency may have an increased risk of metabolic abnormalities after menopause.

The effects of Elaeagnus angustifolia L. whole fruit on the sex hormone profile in menopausal women: A double-blind, randomized, placebo-controlled study

ETHNOPHARMACOLOGICAL RELEVANCE

Menopause is a product of interrupted ovarian activity and decrease in its estradiol production. Herbal medicines as an alternative to hormone therapy are increasingly used by menopausal women. Elaeagnus angustifolia L. (Senjed in Persian) is a well-known herbal remedy with various therapeutic effects according to Iranian traditional medicine which is recommended to relieve the menopausal side effects. The aim of present study was to evaluate the effects of oral intake of whole fruit powder of E. angustifolia on the sex hormones profile in menopausal women.

MATERIALS AND METHODS

In present double-blind randomized placebo-controlled trial, 58 eligible women who were referred to Kamali Women Hospital (Karaj, Iran, 2017) were randomly assigned into herbal medicine (15 g E. angustifolia) and placebo (7.5 g cornstarch +7.5 g isomalt) groups. Initially and after 10 weeks of the treatment, serum levels of estradiol, progesterone, testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) hormones were measured.

RESULTS

According to between-group analyses, the changes in the studied parameters were not significant between herbal medicine and placebo groups, except for joint pain that improved significantly in herbal medicine group. However, by within-group analysis the levels of FSH and FSH to testosterone showed a significant increase, whereas the level of progesterone decreased significantly after 10 weeks of E. angustifolia consumption.

CONCLUSIONS

The improvement of the sex hormone profile was not in a full accordance with Iranian folklore after E. angustifolia consumption in the present menopausal participants. However, considering a strong belief on the beneficial effects of E. angustifolia in Iranian folklore, a long-term studies of larger group participants are needed to evaluate the efficacy.

Jie-Yu Pill, A Proprietary Herbal Medicine, Ameliorates Mood Disorder-Like Behavior and Cognitive Impairment in Estrogen-Deprived Mice Exposed to Chronic Unpredictable Mild Stress: Implication for a Potential Therapy of Menopause Syndrome

Jie-Yu Pill (JYP) is a proprietary herbal medicine initially developed to treat menstrual mood disorders. This study sought to determine whether JYP could alleviate menopausal psychiatric symptoms in ovariectomized (OVX) mice, an animal model of estrogen deprivation, exposed to chronic unpredictable mild stress (CUMS) and the underlying mechanisms in comparison with estrogen therapy. The OVX+CUMS mice were treated with 0.3 mg/kg estradiol (E₂), 2.5 g/kg or 5 g/kg JYP for 36 days, and tested in multiple behavioral paradigms. Serum, uterus, and brain tissues were collected for the measurement of hypothalamus-pituitary-ovarian axis (HPO) and hypothalamus-pituitary-adrenal (HPA) axis hormones, γ-aminobutyric acid (GABA), glutamate, neurotrophins, and estrogen receptors. JYP and E₂ had comparable efficacy in reducing anxiety- and depression-like behavior and cognitive impairment of the OVX+CUMS mice. E₂ strikingly increased ratio of uterus to body weight of the OVX+CUMS mice, but JYP did not. Both agents suppressed HPO-axis upstream hormones, inhibited HPA-axis hyperactivity by reinstating hypothalamic GABA, restored hippocampal and prefrontal glutamate contents and its receptor expression in the OVX+CUMS mice. While JYP and E₂ protected against decreases in hippocampal and prefrontal neurotrophins and estrogen receptors of the OVX+CUMS mice, unlike E₂, JYP had no significant effects on these biomarkers in the uterus. These results suggest that JYP has comparable efficacy in ameliorating mood disorder-like behavior and cognitive impairment induced by a combination of estrogen deprivation and chronic stress in association with certain differential uterus-brain mechanisms compared to estrogen therapy. JYP may be a potential therapy for menopause-associated psychiatric disorders.

Revisiting the effects of menopause on the skin: Functional changes, clinical studies, in vitro models and therapeutic alternatives

Menopause is a stage in a woman's life characterized by twelve months of amenorrhoea. This transition happens due to changes in ovarian follicular activity, leading to endocrine, biological and clinical modifications. The main hormones related to these changes and symptoms are oestradiol, LH, FSH, AMH, Inhibin B and GnRH. It is important to point out that the skin is very affected by all these hormone changes, leading to a decrease in collagen content, water content, elasticity, thickness and impacting on all skin layers quality. Aiming to help women go through this period of their lifetimes with a better quality of life, cosmetic and pharmaceutical industries have studied formulations to improve skin quality. In order to study the safety and efficacy of these products, in vitro methods have been developed in order to mimic menopause and aged skin. In addition to that, many clinical methodologies for skin features assessment have also been improved and applied to evaluate the efficacy of treatments or compounds for menopause. Studying and improving skin models and skin evaluation methodologies may help in the identification of therapeutic targets, treatments, drugs and cosmetics along with new insights for future research in the dermatology field.

The influences of sleep duration, chronotype, and nightwork on the ovarian cycle

Despite research indicating that sleep disorders influence reproductive health, the effects of sleep on reproductive hormone concentrations are poorly characterized. We prospectively followed 259 regularly menstruating women across one to two menstrual cycles (the BioCycle Study, 2005-2007), measuring fasting serum hormone concentrations up to eight times per cycle. Women provided information about daily sleep in diaries and chronotype and night/shift work on a baseline questionnaire. We evaluated percent differences in mean hormone concentrations, the magnitude of shifts in the timing and amplitude of hormone peaks, and the risk for sporadic anovulation associated with self-reported sleep patterns and night/shift work. We estimated chronotype scores - categorizing women below and above the interquartile range (IQR) as "morning" and "evening" chronotypes, respectively. For every hour increase in daily sleep duration, mean estradiol concentrations increased by 3.9% (95% confidence interval [CI] 2.0, 5.9%) and luteal phase progesterone by 9.4% (CI 4.0, 15.2%). Receiving less than 7 hours of sleep per day was associated with slightly earlier rises in peak levels for several hormones. Women reporting night/shift work (n = 77) had lower testosterone relative to women employed without night/shift work (percent difference: -9.9%, CI -18.4, -0.4%). Women with morning chronotypes (n = 47) had earlier rises in estradiol during their cycles and potentially an earlier rise in luteinizing hormone. Compared to those who had intermediate chronotypes, women with evening chronotypes (n = 42) had a later luteinizing hormone peak of borderline statistical significance. A reduced risk for sporadic anovulation was suggested, but imprecise, for increasing hours of daily sleep leading up to ovulation (risk ratio 0.79, CI 0.59, 1.06), while an imprecise increased risk was observed for women with morning chronotypes (risk ratio 2.50, CI 0.93, 6.77). Sleep-related hormonal changes may not greatly alter ovarian function in healthy women, but have the potential to influence gynecologic health.

Addressing Vulvovaginal Atrophy (VVA)/Genitourinary Syndrome of Menopause (GSM) for Healthy Aging in Women

Vaginal health is an essential component of active and healthy aging in women at midlife and beyond. As a consequence of hormonal deprivation and senescence, the anatomy and function of urogenital tissues are significantly affected and vulvovaginal atrophy (VVA) may occur. In a high proportion of postmenopausal women, progressive and chronic VVA symptoms have a strong impact on sexual function and quality of life. The new definition of genitourinary syndrome of menopause (GSM) comprises genital symptoms (dryness, burning, itching, irritation, bleeding), sexual symptoms (dyspareunia and other sexual dysfunctions) and urinary symptoms (dysuria, frequency, urgency, recurrent urinary infections). Many variables (age, sexual activity and partnership status) influence the clinical impact VVA/GSM symptoms and attitudes of elderly women to consult for receiving effective treatments. Psychosocial factors play a critical role in sexual functioning, but the integrity of the urogenital system is as well important affecting many domains of postmenopausal women's health, including sexual function. Several international surveys have extensively documented the need to improve VVA/GSM management because of the strong impact on women's daily life and on couple's intimacy. Health care providers (HCPs) need to be proactive in the early recognition of VVA/GSM in order to preserve urogenital and sexual longevity, by using hormonal and non-hormonal strategies. The clinical diagnosis is based on genital examination to identify objective signs and on the use of subjective scales to rate most bothersome symptoms (MBS), especially vaginal dryness. Recent studies point to the importance of addressing VVA/GSM as a potential early marker of poor general health in analogy with vasomotor symptoms. Therefore, a standard of VVA/GSM care in elderly women is desirable to enhance physical, emotional and mental well-being.

Body image, satisfaction with sexual life, self-esteem, and anxiodepressive symptoms: A comparative study between premenopausal, perimenopausal, and postmenopausal women

Menopause is an important life transition in women, and it is associated with significant physical and psychological changes. This study aimed at examining how the menopausal transition influences body image and satisfaction with sexual life. To this aim, body image dissatisfaction, sexual dissatisfaction, and self-esteem were compared in three groups of women with distinct menopausal status (premenopausal n = 142, perimenopausal n = 66, or postmenopausal n = 149), while controlling for depressive and anxiety symptoms and BMI. Using ANOVA between these three groups, we observed that dissatisfaction with body image was significantly higher in the perimenopausal sample compared with its premenopausal counterpart. In the postmenopausal sample, body image improved, as this group displayed body image scores close to the premenopausal level. In addition, sexual dissatisfaction was significantly increased in the perimenopausal and postmenopausal samples, which is compatible with the concept that higher body appreciation positively predicted sexual function. We conclude that body image dissatisfaction reaches a maximum during the perimenopausal phase, before returning to a level nearly identical between the premenopausal and the postmenopausal phases.

Emerging concepts in the epidemiology, pathophysiology, and clinical care of osteoporosis across the menopausal transition

Bone loss in women accelerates during perimenopause, and continues into old age. To-date, there has been little progress made in stratifying for fracture risk in premenopausal and early postmenopausal women. Epidemiologic data suggests that changes in serum FSH could predict decrements in bone mass during peri- and postmenopause. In bone, FSH stimulates osteoclast formation by releasing osteoclastogenic cytokines. Here, we address the evidence for bone loss across the menopausal transition, discuss strategies for detection and treatment of early postmenopausal osteoporosis, and describe the role FSH plays in physiology and likely in pathophysiology of early postmenopausal bone loss.

Transdermal Testosterone in Female Hypoactive Sexual Desire Disorder: A Rapid Qualitative Systematic Review Using Grading of Recommendations Assessment, Development and Evaluation

Female hypoactive sexual desire disorder (HSDD) is a multifactorial sexual dysfunction disorder characterized by a decrease in sexual desire and personal distress. HSDD occurs in naturally occurring postmenopausal women or secondary to oophorectomy. Multiple studies have assessed the use of transdermal testosterone (TDT) as a management option for patients with HSDD. Our aim is to assess published studies using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework for the quality of evidence regarding testosterone use as a short- and long-term therapy for HSDD. We implemented this qualitative systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. We set a GRADE score of 4 (high evidence) as a cutoff point for the quality measure of published studies assessing the use of TDT in HSDD. The outcomes of interest were the efficacy of TDT on the total number of satisfying sexual activity, number of orgasms, sexual desire and distress level in patients with HSDD. These outcomes were evaluated through Sexual Activity Log (SAL), Profile of Female Sexual Function (PFSF), and Personal Distress Scale (PDS) evaluation tools. Five randomized controlled trials were identified to meet the inclusion criteria. The selected studies were of high evidence based on the GRADE score as two of the studies scored 4 points, the other two studies scored 5 points and one study scored 6 points. All of the high quality selected studies had similar outcomes suggesting high effectiveness for the use of 300 µg/d TDT with or without estrogen for the management of HSDD with minimal side effects. One study showed a trend for higher risk of breast cancer in long-term use (0.37%). The use of 300 µg/d of TDT in surgical and natural menopause is an effective plan to manage HSDD in the short- and long-term. Although side effects are minimal, further prospective research is needed to assess the more severe side effects such as breast cancer in the long-term use of TDT.
