Executive summary of the Stages of Reproductive Aging Workshop + 10: addressing the unfinished agenda of staging reproductive aging

A fNIRS investigation of menopausal-related symptoms and brain cortical activity in menopause

BACKGROUND

This study aimed to delineate the association between menopausal-related symptoms and brain cortical hemodynamics in peri-postmenopause women.

METHODS

Cross-sectional data from a total of 358 Han-Chinese women who visited the Menopause Clinic in the Shanghai Sixth People's Hospital from August 2019 to August 2022. Menopausal-related symptoms were analyzed through Kupperman index (KMI) scale and PSQI scale, while cerebral blood flow was measured using a functional near-infrared spectroscopy (fNIRS). Multiple linear regression model was used to assess the risk factors for subregions of brain hemodynamic response.

RESULTS

After adjusting for confounding factors, we identified that menopausal symptom (B = -1.575, 95 % CI (-2.661, -0.488), p = 0.005) and duration of menopause (B = -14.583, 95 % CI (-26.753, -4.192), p = 0.007) were independently associated with the lower brain hemodynamic response in the prefrontal lobe, while in the temporal lobe, overweight (BMI ≥ 24 kg/m2) was negatively associated with the lower brain cortical activity (B = -36.882, 95 % CI (-72.708, -1.056), p = 0.044) after adjusting for other confounding variables.

CONCLUSIONS

Our findings proposed that menopausal symptom and overweight should be attached great importance to the postmenopausal women, which provides clinical evidence for the feasible early detection and effective prevention such as menopausal hormone therapy (MHT) of brain health in postmenopausal women.

Validation of the Brazilian 10-item Cervantes Scale for the assessment of menopausal symptoms

Objective

To validate the 10-item Cervantes Scale (CS-10) among Brazilian women.

Methods

This is a cross-sectional observational study involving women in the community aged 40-55 years in the Southern region of Brazil. They completed a general health, habits and socio-demographic questionnaire, the CS-10 and the Women's Health Questionnaire (WHQ). Women unable to understand the survey, not consenting to participate, or having incapacity imposing difficulties during the completion of the questionnaire were excluded. A Confirmatory Factor Analysis (CFA) was conducted with the AMOS 16.0 software. Chi-square of degrees of freedom (χ2/df), the Comparative Fit Index (CFI), the Tucker-Lewis Index (TLI) and the Root-Mean-Square Error of Approximation (RMSEA) were used as indices of goodness of fit. Cronbach's alpha coefficient was used for internal consistency.

Results

A total of 422 women were included (premenopausal n=35, perimenopausal n=172, postmenopausal n=215). The CFA for the CS-10 showed a good fit (χ²/df=1.454, CFI=0.989; TLI=0.985; RMSEA=0.033; CI 90%=0.002-0.052; PCLOSE=0.921; Model p=0.049). Good reliability was established in CS-10 and WHQ (Cronbach's alpha=0.724). Postmenopausal women had higher total CS-10 scores (p≤0.0001), reflecting worse quality of life (QoL) related to menopause symptoms and confirming the greater symptomatology evaluated by high total scores for WHQ found in this population when compared to those in the premenopausal period (p=0.041).

Conclusion

The CS-10 is a consistent tool for health-related QoL in Brazilian mid-aged women.

The menopausal transition period and cardiovascular risk

The menopausal transition period spans, on average, 2-8 years before the final menstrual period and is associated with an increase in clinical and subclinical cardiovascular risk. In this Review, we discuss the metabolic and cardiovascular changes that occur during the menopausal transition period and the role of ovarian ageing, chronological ageing and other ageing-related risk factors in mediating these changes. Disentangling the relative contributions of chronological and reproductive ageing to cardiovascular risk is challenging, but data from longitudinal studies in women transitioning from premenopause to post-menopause have provided valuable insights. We also discuss evidence on how cardiovascular risk is altered by premature or early menopause, surgical menopause, and vasomotor and other menopausal symptoms. Whether targeted interventions can slow the progression of atherosclerosis and subclinical disease during the menopausal transition, thus delaying or preventing the onset of cardiovascular events, remains to be determined. Furthermore, we consider the recommended strategies for cardiovascular risk reduction in women undergoing menopausal transition using the framework of the American Heart Association's Life's Essential 8 key measures for improving and maintaining cardiovascular health, and discuss the cardiovascular risks and benefits of menopausal hormone therapy. Finally, we also discuss novel therapies that might benefit this population in reducing cardiovascular risk.

Stress, depression, and anxiety: psychological complaints across menopausal stages

Introduction

With the number of menopausal women projected estimated to reach 1.2 billion by 2030 worldwide, it is critically important to understand how menopause may affect women's emotional well-being and how many women are affected by this. This study aimed to explore (i) the relationship between psychological complaints (depression, anxiety, poor memory) across different menopausal stages and (ii) investigate the correlation between resilience, self-efficacy, and perceived stress levels, with psychological complaints and whether this was associated with menopausal stage and/or age.

Methods

287 respondents completed the Menopausal Quality of Life (MenQoL), Perceived Stress Scale (PSS-10), Brief Resilience Scale (BRS), and General Self-efficacy (GSE) scales. Parametric and non-parametric analysis were used to analyse how bothered women were by self-reported poor memory and feelings of depression and anxiety, alongside perceived stress, resilience, and self-efficacy between women in different menopausal stages using STRAW criteria. The association between protective factors (self-efficacy and resilience) and psychological complaints was analysed with partial correlation analysis controlling for menopausal stages and/or age.

Results

A significant difference was found between the levels of perceived stress, and how bothered women were by feelings of depression and anxiety between early-perimenopausal and post-menopausal women. However, with the inclusion of age as a covariate, menopausal stage no longer predicted the level of self-reported stress and anxiety in menopausal women. There was also no difference between poor self-reported memory, or of self-efficacy or resilience between women in different menopausal stages. However, self-efficacy and resilience were associated with how bothered women were by feelings of depression and anxiety, and the experience of stress. Stress was the only variable to be associated with poor self-reported memory independent of age and/or menopausal status.

Discussion

Early perimenopausal women experienced the highest level of stress and were more severely bothered by feelings of depression and anxiety, with the poorest overall self-reported psychosocial quality of life. Post-menopausal women, however, reported to have similar experiences as premenopausal women. Age explained the associations between menopausal stage, stress and anxiety, but not between depression and different menopausal stages. Resilience and self-efficacy were associated with psychological complaints independent of menopausal stage and age, suggesting that therapies focusing on increasing resilience and self-efficacy may be beneficial to help target these psychological complaints at any time.

Effect of Menopause Status on Brain Perfusion Hemodynamics

BACKGROUND

The menopause transition is associated with an increasing risk of cerebrovascular disorders. However, the direct effect of menopause status on brain perfusion hemodynamics remains unclear. This study aimed to explore the influence of menopause status on cerebral blood flow (CBF) using arterial spin labeling magnetic resonance imaging.

METHODS

In this cross-sectional study, 185 subjects underwent arterial spin labeling magnetic resonance imaging at a hospital in China between September 2020 and December 2022, including 38 premenopausal women (mean age, 47.74±2.02 years), 42 perimenopausal women (mean age, 50.62±3.15 years), 42 postmenopausal women (mean age, 54.02±4.09 years), and 63 men (mean age, 52.70±4.33 years) of a similar age range. Mean CBF values in the whole brain, gray matter, white matter, cortical gray matter, subcortical gray matter, juxtacortical white matter, deep white matter, and periventricular white matter were extracted. ANCOVA was used to compare mean CBF among the 4 groups, controlling for confounding factors. Student t test was applied to compare mean CBF between the 3 female groups and age-matched males, respectively. Multivariable regression analysis was used to analysis the effect of age, sex, and menopause status on the CBF of the whole brain, gray matter, white matter, and subregions.

RESULTS

Perimenopausal and postmenopausal women showed a higher proportion of white matter hyperintensities compared with the other 2 groups (P<0.001). Premenopausal women exhibited higher CBF in the whole brain, gray matter, white matter, and subregions, compared with perimenopausal, postmenopausal women and men (P≤0.001). Multivariable regression analysis demonstrated significant effect of age and insignificant effect of sex on CBF for all participants. In addition, menopause status and the interaction between age and menopause status on CBF of whole brain, gray matter, white matter, and the subregions were observed in female participants, except for the deep and periventricular white matter regions, with premenopausal women exhibited a slight increase in CBF with age, while perimenopausal and postmenopausal women exhibited declines in CBF with age.

CONCLUSIONS

The current findings suggest that alterations of brain perfusion hemodynamics begin during the perimenopause period, which may be due to the increased burden of white matter hyperintensities.

Research progress on the treatment of perimenopausal insomnia with Chaihu Jia Longgu Muli decoction based on brain-intestine-bacteria axis: A review

With the progress and rapid societal development, women are confronted with multifaceted pressures in their lives, encompassing familial and other domains. Furthermore, during the perimenopausal phase, endocrine equilibrium is disrupted, leading to the emergence of psychological and physiological health challenges. Insomnia is a prevalent symptom among perimenopausal individuals. The brain-gut-bacteria axis assumes a pivotal role in the prevention, diagnosis, and management of perimenopausal insomnia. Chaihu Jia Longgu Muli decoction is a commonly prescribed remedy for addressing perimenopopausal insomnia. Consequently, this paper aims to investigate the interplay between the brain-gut-bacteria axis, intestinal microbiota, and the pathogenesis of perimenopausal insomnia. The study focuses on examining the regulatory effects of Chaihu Jia Longgu Muli decoction on the nervous system, intestinal microbiota, and the hypothalamus-pituitary-adrenal axis. Additionally, it explores the mechanisms underlying Hujia Longgu Muli decoction in mitigating perimenopausal insomnia.

Calculation of left ventricular ejection fraction using an 8-layer residual U-Net with deep supervision based on cardiac CT angiography images versus echocardiography: a comparative study

Background

Accurate segmentation of the left ventricle (LV) is an important step in assessing cardiac function. Cardiac CT angiography (CCTA) has become an important means of clinical diagnosis of cardiovascular diseases (CVDs) because of its advantages of non-invasive, short examination time and low cost. In order to obtain the segmentation of LV in CCTA scans, we propose a deep learning method based on 8-layer residual U-Net with deep supervision. In this study we compared the left ventricular ejection fraction (LVEF) calculated by deep learning (DL) method (AccuLV) from CCTA to LVEF by conventional two-dimensional echocardiography (EC).

Methods

This was a retrospective cross-sectional study, and consecutive patients who had undergone CCTA and EC in our hospital from February 2021 to May 2021 were recruited. The current study included 180 patients who had undergone CCTA and EC. To obtain LVEF, we used an 8-layer residual U-Net with deep supervision to segment LV contours from CCTA images and compute LVEF (DL-LVEF). The EC and DL-LVEF measurements were compared. A 50% EC-LVEF cut-off value was used as a reference standard to assess the diagnostic performance of AccuLV in assessing LV function.

Results

The overall mean EC-LVEF and DL-LVEF values were 64.0% (52.3%, 69.0%) and 73.0% (52.3%, 77.0%), respectively. Three patient groups were studied: (I) hypertensive patients, (II) postmenopausal women, and (III) diabetes. EC-LVEF and DL-LVEF were found to be positively correlated for all of the included patients (r=0.82, P<0.001), with the detailed results for the three groups as follows: hypertensive patients (r=0.77, P<0.001), postmenopausal women (r=0.92, P<0.001) and diabetes (r=0.88, P<0.001). The diagnostic accuracy, sensitivity, and specificity of the DL method in predicting EC-LVEF <50% for all patients were 93.9%, 92.3%, and 94.3%, and for hypertensive patients were 95.4%, 93.8%, and 95.8%, for postmenopausal women were 87.0%, 100%, and 84.2%, for diabetes were 97.4%, 100%, and 96.6%.

Conclusions

In comparison to echocardiography, which is commonly used in clinical setting, AccuLV may be a promising, fully automated tool for rapid and accurate quantification of LV function and thus for making reliable clinical decisions.

Epidemiology and Nomogram for Predicting the Cancer-specific Survival of Ovarian Granulosa Cell Tumor: A Seer database study

OBJECTIVE

ovarian granulosa cell tumor (OGCT) is a kind of infrequent ovarian malignant tumor with limited epidemiological data available. we established a predictive nomograph to verify the clinical prognosis.

METHODS

1005 diagnosed with ovarian granulosa cell tumor (OGCT) were extracted from Surveillance, Epidemiology, and End Results (SEER) public database from 2000-2018. Kaplan-Meier analysis was applied to distinguish risk factors, univariate and multivariate Cox analyses were used to determine the independent prognostic factors for cancer-specific survival (CSS) of OGCT patients. The obtained prognostic variables were combined to construct a nomogram model for predicting CSS in OGCT patients.

RESULTS

Model performance was detected and evaluated with ROC curves and calibration plots. Data collected from 1005 patients were divided into two groups: training cohort(n=703,70%) and validation cohort(n=302,30%). The multivariate Cox model identified five covariates including age, marital status, AJCC stages, surgery and chemotherapy as independent interfering factors of CSS. The nomogram has shown a promising and excellent accuracy in evaluating 3 -, 5 -, 8-year CSS in OGCT patients. In terms of the CSS of the training cohort, the AUC values of the 3 -, 5 -, 8-year ROC curves were 0.819,0.8,0.819, while in terms of the CSS of the validation cohort, the AUC values of the validation cohort were 0.822,0.84,0.823, respectively. All the calibration curves showed pleasant consistency between predicted and actual survival rates. The nomogram model established in the study can improve the veracity of prognosis prediction, thereby improving the accuracy of individualized survival risk assessment, and providing targeted and constructive recommendations for specific treatment options.

CONCLUSION

Age, advanced clinical stage, widower and without surgery therapy are independent risk factors for poor prognosis and the nomogram we constructed can help clinicians efficiently recognize high-risk OGCT patients to guide targeted therapies and improve their outcomes.

Network segregation in aging females and evaluation of the impact of sex steroid hormones

Males and females show differential patterns in connectivity in resting-state networks (RSNs) during normal aging, from early adulthood to late middle age. Age-related differences in network integration (effectiveness of specialized communication at the global network level) and segregation (functional specialization at the local level of specific brain regions) may also differ by sex. These differences may be due at least in part to endogenous hormonal fluctuation, such as that which occurs in females during midlife with the transition to menopause when levels of estrogens and progesterone drop markedly. A limited number of studies that have investigated sex differences in the action of steroid hormones in brain networks. Here we investigated how sex steroid hormones relate to age-network relationships in both males and females, with a focus on network segregation. Females displayed a significant quadratic relationship between age and network segregation for the cerebellar-basal ganglia and salience networks. In both cases, segregation was still increasing through adulthood, highest in midlife, and with a downturn thereafter. However, there were no significant relationships between sex steroid hormone levels and network segregation levels in females, and they did not exhibit significant associations between progesterone or 17β-estradiol and network segregation. Patterns of connectivity between the cerebellum and basal ganglia have been associated with cognitive performance and self-reported balance confidence in older adults. Together, these findings suggest that network segregation patterns with age in females vary by network, and that sex steroid hormones are not associated with this measure of connectivity in this cross-sectional analysis. Though this is a null effect, it remains critical for understanding the extent to which hormones relate to brain network architecture.

Palpitations across the menopause transition in SWAN: trajectories, characteristics, and associations with subclinical cardiovascular disease

OBJECTIVE

Our objectives were to identify trajectories of palpitations over the menopause transition, characterize them, and examine associations with subclinical cardiovascular disease (CVD).

METHODS

We analyzed the following data from the multisite, multiethnic SWAN (Study of Women Across the Nation): reported palpitations occurrence over time; baseline sociodemographic, reproductive, medication, and health-related factors; and follow-up visit subclinical CVD (carotid atherosclerosis, vascular stiffness). Trajectories of palpitations (n = 3,276), their characteristics, and their associations with subclinical CVD (n = 1,559) were identified using group-based trajectory modeling and linear and logistic regression models.

RESULTS

Three trajectories emerged: high probability of palpitations in perimenopause to early postmenopause diminishing in late postmenopause (15.9% of women), moderate probability of palpitations in perimenopause to early postmenopause diminishing in late postmenopause (34.3%), and sustained low probability of palpitations (49.8%). In the fully adjusted multivariable model, the high probability group had a more adverse reproductive and health-related profile at baseline (higher gravidity, early perimenopause, vasomotor symptoms, poorer overall health, higher depressive symptoms, higher perceived stress, greater sleep problems, higher blood pressure). In fully adjusted multivariable models, palpitation trajectories were not related to atherosclerosis or arterial stiffness.

CONCLUSIONS

Distinct patterns of palpitations emerged, with a substantial portion of women having palpitations during the perimenopause and early postmenopause. Palpitations were not associated with subclinical CVD. Findings can help identify women at risk of palpitations during the menopause transition who may need symptom relief.

Metabolic Syndrome, BMI, and Polymorphism of Estrogen Receptor-α in Peri- and Post-Menopausal Polish Women

The study aimed to investigate the association between the estrogen receptor alpha (ERα) polymorphism and the prevalence of metabolic syndrome (MetS) and obesity, as well as the coexistence of MetS and obesity, in peri- and post-menopausal Polish women. The study group consisted of 202 peri-menopausal and 202 post-menopausal women. ERα polymorphism: Xba I and Pvu II, MetS, BMI, and serum estrogen concentration were analyzed. MetS was found in 29% of the peri-menopausal women and in 21% of the post-menopausal women. BMI did not significantly differ between the peri- and post-menopausal women (≈42% were normal weight, ≈40% were overweight, and ≈18% were obese), (p = 0.82). Serum estrogen concentration in the peri-menopausal women was 91 ± 75 pg/mL, while that in the post-menopausal women was 17 ± 9. pg/mL, on average. Peri-menopausal women with AA and TT genotypes of the ERα polymorphism have a lower risk of obesity and MetS and the co-existence of obesity and MetS, whereas those women with the G or C allele have a higher risk of those health problems.

The Impact of Soy Isoflavone Supplementation on the Menopausal Symptoms in Perimenopausal and Postmenopausal Women

Introduction

Approximately one-third of a woman's life is spent in the menopausal phase. The unpleasant menopausal symptoms are unacceptable as a part of routine life. Indications of menopausal hormone therapy (MHT) are for alleviation of vasomotor symptoms, prevention of osteoporosis, and genitourinary symptoms associated with menopause. MHT is associated with an increased risk of breast cancer, cerebrovascular accidents, and coronary heart disease. Soy isoflavones have been extensively used as an alternative treatment in patients who cannot take MHT. The evidence of the efficacy of isoflavones in the literature is equivocal.

Aim

The aim of the study was to evaluate the efficacy of soy isoflavone supplementation on menopausal symptoms in perimenopausal and postmenopausal women and to evaluate the effect on blood pressure (BP) and body mass index (BMI).

Materials and Methods

A questionnaire-based prospective observational study was undertaken involving 39 perimenopausal and 61 postmenopausal women, who were prescribed 40 mg soy isoflavone supplements twice daily for 12 weeks. Menopause Rating Scale questionnaire was given to the patients before starting soy isoflavone therapy and at the end of the treatment; BP and BMI were also noted.

Results

The total score of both the groups was comparable at baseline. Among perimenopausal and postmenopausal women, the highest score was noted in symptoms of somatic domain. At the completion of our study, the total scores improved significantly by 38.6% and 33.3% in perimenopausal and postmenopausal women, respectively. The greatest improvement was seen in somatic subscale (42.5%) and psychological subscale (42.5%) and the least in urogenital subscale (16.1%) for perimenopausal women. For postmenopausal women, the greatest improvement was seen in psychological subscale (40.0%) and the least in urogenital subscale (14.2%).

Conclusion

Soy isoflavone supplementation is beneficial in both perimenopausal and postmenopausal women, more so in perimenopausal women. There is no beneficial effect of soy isoflavone supplementation on lowering systolic BP and BMI.

Hormone therapy regimens for managing the menopause and premature ovarian insufficiency

The transition to menopause is associated with a changing hormonal milieu, leading to bothersome menopausal symptoms in the short-term and chronic health problems in the long-term. Premature ovarian insufficiency (POI) is characterized by the cessation of menses before the age of 40 years. Hormone replacement therapy (HRT) is indicated to restore sex hormones to normal premenopausal levels and prevent chronic diseases, such as osteoporosis and cardiovascular disease. Menopausal hormone therapy (MHT) is indicated in perimenopausal and postmenopausal women over 45 years of age for managing menopausal symptoms, symptoms of vulvovaginal atrophy, and reducing the risk of postmenopausal osteoporosis. Individualization is the key to management, aiming at maximizing efficacy and minimizing clinically relevant risks. This review aimed to present the hormone therapy regimens for women during the transition or after menopause and women with POI and early menopause, as well as advise on: i) the initiation of MHT, ii) steps for monitoring during follow up, iii) weaning and discontinuation of treatment.

Neuroprotective effects of Tiaogeng decoction against H2O2-induced oxidative injury and apoptosis in PC12 cells via Nrf2 and JNK signaling pathways

ETHNOPHARMACOLOGICAL RELEVANCE

Tiaogeng decoction (TGD), a mixture of 10 traditional Chinese herbs, has been used clinically for over 30 years in treating menopause-related symptoms such as cognitive changes, mood disorders, vasomotor symptoms, and sleep disorders. These central nervous system symptoms are closely associated with declined ovarian function, which dramatically increases the risk of neurodegenerative disease. Previous studies revealed that TGD may have anti-oxidative and anti-apoptotic properties, potentially preventing neurodegenerative conditions; however, the underlying pharmacological mechanism remains unclear.

AIM OF THE STUDY

This study aimed to examine whether TGD could activate the Nrf2 and C-Jun N-terminal kinase (JNK) signaling pathways to effectively reduce oxidative injury and apoptosis in PC12 cells and elucidate the mechanism by which this medicine may prevent neurodegenerative disease.

MATERIALS AND METHODS

PC12 cells were exposed to different concentrations of TGD (125, 250, 500 μg/mL) and H₂O₂ (150 μM). 17β-estradiol (0.05 μg/mL) was used as the positive control. A cell counting kit-8 (CCK-8) and a lactate dehydrogenase (LDH) assay were used to detect cell viability and cytotoxicity, while Hoechst and flow cytometry were performed to evaluate apoptosis levels. Mitochondrial function was assessed by measuring mitochondrial membrane potential (MMP), and superoxide dismutase (SOD), and reactive oxygen species (ROS) levels were used to measure oxidative stress (OS). Western blot analysis was used to identify the levels of Nrf2, phospho-JNK (p-JNK), phospho-mitogen-activated protein kinase kinase 7 (p-MKK7), Kelch-like ECH-associated protein 1 (Keap1), heme oxygenase-1 (HO-1), Caspase3 (Casp3), Caspase9 (Casp9), Bax, and Bcl-2 proteins. Moreover, JNK agonist anisomycin and Nrf2 inhibitor ML385 were used to validate pathways.

RESULTS

TGD pretreatment significantly alleviated H₂O₂-induced cytotoxicity, apoptosis, MMP, and OS levels. H₂O₂ stimulated the activation of Nrf2 and JNK signaling pathways, but TGD increased the extent of Nrf2 antioxidant activation, decreased the activation of JNK, and eventually reversed the H₂O₂-induced protein expression of p-MKK7, Keap1, HO-1, Cleaved Caspase3 (CL-Casp3), Cleaved Caspase9 (CL-Casp9), Bax, and Bcl-2.

CONCLUSIONS

This study's findings suggest that TGD may attenuate oxidative injury and apoptosis via the Nrf2 and JNK signaling pathways, making it a potential therapeutic candidate for neurodegenerative diseases.

Assessing the efficacy of a structured stress management program in reducing stress and climacteric symptoms in peri- and postmenopausal women

To evaluate the effectiveness of a structured education program on lifestyle habits, which is also incorporating teaching on deep breathing, progressive muscle relaxation, and guided visualization, in the control of various components of the climacteric symptomatology in peri- and postmenopausal women. Sixty-one women aged 40-65 years with varying climacteric and stress symptoms were included in this study. Women were randomly assigned to the intervention group (31) or the control group (30). The intervention group followed an 8-week stress management program. The following parameters were assessed at baseline and at the end of the 8-week follow-up period in both groups: climacteric symptoms (Green Climacteric Scale (GCS)), sleep quality (Pittsburg Sleep Quality Index (PSQI)), mood status (Depression-Anxiety-Stress Scale), self-esteem (Rosenberg Self-esteem Scale), and health-related control (health locus of control (HLC)). A mixed-model ANOVA showed significant time × group × GCS interaction (within subjects: F = 23.830, p value<0.001; between subjects: F = 39.078, p value<0.001). With regard to HLC, there was a non-significant between subjects but a significant within-subjects effect (HLC × group × time, F = 3.848, p value = 0.024). Regarding DASS scores, there was a significant between-subjects' effect (F = 10.258, p value = 0.003) but a non-significant within-subjects' effect. With regard to PSQI, the analysis showed significant within-subjects' effects (PSQI × group × time: F = 4.691, p value = 0.003) and non-significant between-subjects' effects (F = 0.022, p = 0.883). Finally, regarding RSS, there was a significant within-subjects' (RSS × group × time, F = 4.183, p value = 0.029) but non-significant between-subjects' effect (F = 1.582, p value = 0.213). Stress management may offer an alternative approach to the management of climacteric symptoms.

Impact of age and menopausal stage on serum anti-Müllerian hormone levels in middle-aged women

OBJECTIVE

This study aimed to evaluate the association between age, menopausal stage and serum anti-Müllerian hormone (AMH) levels in middle-aged women.

METHODS

In this cross-sectional study, the serum AMH levels of 288 healthy women aged 40-55 years (divided into age groups: 40-44, 45-49 and 50-55 years) were evaluated. Stages of Reproductive Aging Workshop + 10 criteria were used to categorize these women into menopausal stages: late reproductive, menopausal transition and early postmenopausal stages. The impact of age, menopausal stage and hormone replacement therapy on serum AMH levels was analyzed using multi-factor analysis of variance. Effects of body mass index, smoking status and oral contraceptive use were simultaneously considered.

RESULTS

The median AMH level was 0.140 ng/ml. Log-AMH levels varied according to age group (variance = 20.113, F = 88.538, p < 0.001) and menopausal stage (variance = 5.543, F = 24.501, p < 0.001). An exponential model defined as AMH = 227,421.757 × e^{(-0.301 × age)} was fit to describe the decline in AMH level with age. The 5th-95th percentiles of the AMH levels ranged from less than 0.020 to 3.150, less than 0.020 to 1.944 and less than 0.020 to 0.030 ng/ml in the aforementioned menopausal stages, respectively.

CONCLUSION

Age and menopausal stage were associated with AMH levels; age had a greater impact on AMH than menopausal stage in middle-aged women.

Identification and Functional Characterization of Metabolites for Bone Mass in Peri- and Postmenopausal Chinese Women

CONTEXT

Although metabolic profiles appear to play an important role in menopausal bone loss, the functional mechanisms by which metabolites influence bone mineral density (BMD) during menopause are largely unknown.

OBJECTIVE

We aimed to systematically identify metabolites associated with BMD variation and their potential functional mechanisms in peri- and postmenopausal women.

DESIGN AND METHODS

We performed serum metabolomic profiling and whole-genome sequencing for 517 perimenopausal (16%) and early postmenopausal (84%) women aged 41 to 64 years in this cross-sectional study. Partial least squares regression and general linear regression analysis were applied to identify BMD-associated metabolites, and weighted gene co-expression network analysis was performed to construct co-functional metabolite modules. Furthermore, we performed Mendelian randomization analysis to identify causal relationships between BMD-associated metabolites and BMD variation. Finally, we explored the effects of a novel prominent BMD-associated metabolite on bone metabolism through both in vivo/in vitro experiments.

RESULTS

Twenty metabolites and a co-functional metabolite module (consisting of fatty acids) were significantly associated with BMD variation. We found dodecanoic acid (DA), within the identified module causally decreased total hip BMD. Subsequently, the in vivo experiments might support that dietary supplementation with DA could promote bone loss, as well as increase the osteoblast and osteoclast numbers in normal/ovariectomized mice. Dodecanoic acid treatment differentially promoted osteoblast and osteoclast differentiation, especially for osteoclast differentiation at higher concentrations in vitro (eg,10, 100 μM).

CONCLUSIONS

This study sheds light on metabolomic profiles associated with postmenopausal osteoporosis risk, highlighting the potential importance of fatty acids, as exemplified by DA, in regulating BMD.

Association of Visceral and Subcutaneous Fat Mass With Bone Density and Vertebral Fractures in Women With Severe Obesity

INTRODUCTION

The aim of this study was to evaluate the association of visceral and subcutaneous adipose tissue with bone mineral density (BMD), geometric indices of femoral neck strength and vertebral fractures in pre- and postmenopausal women with severe obesity.

METHODS

A cross-sectional study was conducted with pre- (n = 37) and postmenopausal (n = 21) women with body mass index higher than 40 kg/cm². BMD at total body, lumbar spine, hip and forearm, presence of vertebral fractures, lean mass, visceral, and subcutaneous adipose tissue were assessed by DXA. Geometric indices of femoral neck strength were calculated by DXA. Serum bone turnover markers (CTX and osteocalcin) and 25(OH)D were also measured.

RESULTS

BMD at all studied sites was similar in pre- and postmenopausal women. In postmenopausal women, total subcutaneous adipose tissue was inversely associated with BMD at total femur (β = -0.009; 95% confidence interval [CI] -0.017; -0.002) and with strength index (β = -0.03; 95% CI -0.04; -0.01). In premenopausal women, visceral adipose tissue was inversely associated with cross-sectional moment of inertia (β = -0.95; 95%CI -1.89; -0.01). Vertebral fractures were highly prevalent in premenopausal (32%), and even more frequent among postmenopausal women (55%).

CONCLUSION

Taken together, our results suggest that both visceral and subcutaneous fat may be detrimental for bone health in pre- and postmenopausal women, and that severe obesity may increase the risk of vertebral fractures, even in young women.

[How to diagnose menopause? Postmenopausal women management: CNGOF and GEMVi clinical practice guidelines]

The diagnosis of menopause is sometimes difficult. The objective of this chapter is to describe the process of diagnosing menopause in a physiological situation, then in different clinical situations: women using hormonal contraception (per os, implant or intrauterine device), women with a history of hysterectomy, women previously treated for cancer. A review of the literature was carried out via Pubmed, Medline and Cochrane Library. The recommendations of international societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, European Menopause and Andropause Society (EMAS) https://www.emas-online.org. In a classic situation, the diagnosis of menopause is a clinical diagnosis, made retrospectively, based on a 12-month period of consecutive amenorrhoea in a compatible age group (after 45 years of age). No hormonal dosage or imaging is indicated to make a diagnosis of menopause in a classic situation. In women using oestroprogestogen or progestative-only-pill contraception, implant, or Levonorgestrel-intrauterine device (LNG IUD), hormonal assays or pelvic ultrasound are neither recommended to make a diagnosis of menopause (grade C), nor to decide to stop contraception (grade C). The proposed strategy is the discontinuation of oral contraception, removal of the implant or LNG-IUD, and clinical follow-up (occurrence of amenorrhea) (expert opinion). In women with a history of hysterectomy, in the absence of evaluable clinical symptoms (amenorrhea), a repeat FSH≥40 combined with low estradiol (<20pg/ml) at least 3 months after the procedure could be a diagnostic orientation towards menopausal status. After cancer, in women who have received gonadotoxic treatment, the classic clinical criteria of 12 months of amenorrhea cannot be used to make a diagnosis of menopause with certainty (expert opinion). No further examination can be recommended to make a definite diagnosis of menopause (expert opinion). In breast cancer, the hormonal status to be taken into account when choosing initial hormone therapy is the one found before starting any treatment. If at the time of diagnosis of breast cancer the menopausal status is not known due to hormonal contraception, it is preferable to consider the patient as non-menopausal by default for the choice of hormone therapy for the cancer.

Increase in C-Reactive Protein Predicts Increase in Rate of Bone Mineral Density Loss: The Study of Women's Health Across the Nation

This longitudinal cohort study's aim was to detect whether larger increases in C-reactive protein (CRP) predict greater amounts of subsequent bone loss in women transitioning from premenopause to postmenopause. Participants were initially 42 to 52 years of age and premenopausal or early perimenopausal. The sample included 1431 women who were not using hormone therapy and whose CRP values were not consistent with acute inflammation. Individual fixed effects (IFE) models estimated the association of log₂ CRP with subsequent bone mineral density (BMD) decline rate, adjusted for menopause transition (MT) stage (1: premenopausal or early perimenopausal; 2: late perimenopausal or early postmenopausal; or 3: late postmenopausal), body mass index, diabetes, smoking, alcohol, bone active medications, and anti-inflammatory medications. BMD decline at both the lumbar spine (LS) and femoral neck (FN) was faster for observations made in MT stage 2 than that during other stages (all p < .001). In adjusted IFE models, MT stage modified the relation between increase in CRP and BMD decline rate (interaction p values <.05). Each within-woman doubling of CRP was associated with a 0.09% faster yearly decline in FN BMD in MT stages 1 (p = .006) and 3 (p = .03), and 0.10% faster decline in LS BMD in MT stage 3 only (p = .007). Within-woman increases in CRP in premenopause and early perimenopause and in late postmenopause predict faster BMD decline in the next ~2 years, but the magnitude of CRP's effect is small. © 2021 The Authors.

Depressive Symptoms and Healthy Behavior Frequency in Polish Postmenopausal Women from Urban and Rural Areas

The objective of this study was to determine whether the severity of depressive symptoms was linked to healthy behaviors in Polish postmenopausal women and whether the strength of the link differed between women living in urban versus rural settings. The study was conducted in 2018 in the Lublin region of Poland and included 396 postmenopausal women (239 living in rural areas and 157 in urban areas). The severity of depressive symptoms was evaluated by the Beck Depression Inventory (BDI) and the frequency of healthy behaviors was assessed using the Inventory of Healthy Behaviors. Postmenopausal women living in rural areas underwent menopause significantly earlier, were more often widowed, more often obese, more often less educated, and less likely to have never married when compared to those living in urban areas. Importantly, rural postmenopausal women endorsed more depressive symptoms (p = 0.049). There was a negative correlation between the severity of depressive symptoms and age in urban postmenopausal women (r = −0.174, p = 0.029), but this was not evident in rural women (r = −0.034, p = 0.600). The frequency of healthy behaviors was significantly lower in rural postmenopausal women, especially with respect to nutritional habits. A positive correlation was found between the frequency of healthy behaviors and the level of education in both sets of women (p = 0.034 and p = 0.045, respectively). To summarize, we found a significant link between healthy behaviors and depressive symptoms in postmenopausal women. We also found that this link was more evident in rural than in urban women.

Transitioning to the menopausal transition: a scoping review of research on the late reproductive stage in reproductive aging

IMPORTANCE AND OBJECTIVE

In 2001 Staging Reproductive Aging Workshop conferees described the late reproductive stage (LRS) of reproductive aging as preceding the onset of the menopausal transition, yet there has been little attention to this aspect of reproductive aging. The aim of this scoping review was to examine scientific publications characterizing the LRS to map what is known about this stage with particular focus on reproductive endocrine patterns, menstrual cycle changes, and symptoms.

METHODS

The initial search strategy included PubMed and CINAHL searches for the phrase LRS and "human." Given a low yield of research articles, a second stage used "late reproductive age" (LRA) as a search term. These strategies yielded 9 and 26 research articles, respectively. Publications meeting inclusion criteria (data-based research studies, focus on LRS or LRA and hormonal patterns, menstrual characteristics, and symptoms) published in English were reviewed by coinvestigators. Excluded studies were related to specific diseases, such as cardiovascular disease, and treatment studies. Data were summarized using qualitative methods. To ensure adequate coverage of published research we expanded our review to a third phase in which we identified longitudinal studies of the menopausal transition.

DISCUSSION AND CONCLUSIONS

Studies of the LRS focused on: symptoms (anxiety and mood symptoms, bladder symptoms, urinary incontinence, urinary frequency, and nocturia) and associated factors, such as endocrine levels and gene polymorphisms; symptom clusters women experienced during the LRS; cognitive function testing results; changing patterns of physiology such as cytokines and chemokines, lipids, hormone patterns/levels; and association of lifestyle factors such as smoking with hormone levels and symptoms. The LRA search yielded a preponderance of studies of reproductive hormones (such as anti-Mullerian hormone) and menstrual cycle patterns. Remaining studies focused on symptoms, gene variants, health-related behaviors and approaches to classifying menstrual cycles. Longitudinal studies revealed reports of symptoms as well as attempts to classify the progression from the reproductive years to the menopausal transition. Study of the LRS has not been systematic and the limited number and scope of completed studies have yet to contribute a clear and complete picture of the LRS. In some, LRS provided a comparison stage against which to evaluate menopausal transition hormonal and cycle patterns and symptoms. Harmonizing the results of studies of the LRS and LRA is essential to understand more completely women's experiences of the LRS and to allow clinicians to provide better support for women during this time. The LRS also represents an ideal inflection point to promote lifestyle choices that could alter the trajectories of chronic diseases that arise in the fifth, sixth, and seventh decades of women's lives.

A Systematic Review of Palpitations Prevalence by Menopausal Status

Purpose of the Review

The purpose was to systematically review evidence on the prevalence of palpitations by menopausal stage. Palpitations are a feeling of missed, irregular, or exaggerated heart beats.

Recent Findings

Carefully delineated search, screening, and data extraction strategies resulted in five articles for review. Articles offered cross-sectional findings from menopausal symptom surveys from five countries between 1974 and 2011 with clinic- and community-based samples of premenopausal, perimenopausal, and postmenopausal women. Reported studies were good (n = 2) to fair (n = 3) quality with low (n = 2) to moderate (n = 3) bias. Menopausal palpitations were not the focus of any study but were assessed as a single item of heart racing, pounding, or discomfort over the past 2 weeks, month, or year. Palpitations prevalence rates by menopausal stage were 3.7 to 40.2% premenopausal, 20.1 to 40.2% perimenopausal, and 15.7 to 54.1% postmenopausal. Three of five articles showed that compared with premenopausal and postmenopausal women, palpitation prevalence was significantly higher among perimenopausal and surgically postmenopausal women.

Summary

Good-quality evidence on palpitation prevalence by menopausal stage is limited but suggests that physiological changes of menopause may play a role in this symptom. Measurement varied, suggesting a need to standardize the assessment of menopausal palpitations. The review findings suggest a strong need for clinicians and researchers to collaborate to standardize documentation of menopausal palpitations across the menopause transition.

Altered Spontaneous Brain Activity in Women During Menopause Transition and Its Association With Cognitive Function and Serum Estradiol Level

OBJECTIVE

Serum hormone deficiencies during menopause transition may affect spontaneous brain activity and global cognition. The purpose of this study was to explore the differences in spontaneous brain activity between premenopausal and perimenopausal women, and to investigate the associations between spontaneous brain activity, serum hormone levels and global cognition.

METHODS

Thirty-two premenopausal women (47.75 ± 1.55 years) and twenty-five perimenopausal women (51.60 ± 1.63 years) underwent resting-state functional MRI (fMRI) scan. Clinical information including Mini-Mental State Examination (MMSE), levels of estradiol (E2), free testosterone, progesterone, prolactin, follicle-stimulating hormone and luteinizing hormone were measured. Regional homogeneity (ReHo) was used to evaluate spontaneous brain activity alterations between perimenopausal and premenopausal women. Correlation analysis was used to investigate the associations between brain functional alterations and clinical measures in perimenopausal group.

RESULTS

The results demonstrated increased ReHo value in the right lingual gyrus (LG) and decreased ReHo value in the right superior frontal gyrus (SFG) in perimenopausal women compared with premenopausal women. In perimenopausal group, ReHo of the right LG showed a negative correlation with level of E2 (r = -0.586, p = 0.002), ReHo of the right SFG showed a positive correlation with level of E2 (r = 0.470, p = 0.018) and MMSE (r = 0.614, p = 0.001).

CONCLUSIONS

The results demonstrated that women approaching menopause suffered from altered functions in brain regions related to cognitive function, working memory, the results also revealed a direct association between levels of E2 and brain functions in perimenopausal women.

Menopause Transition and Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association

Cardiovascular disease (CVD) is the leading cause of death in women, who have a notable increase in the risk for this disease after menopause and typically develop coronary heart disease several years later than men. This observation led to the hypothesis that the menopause transition (MT) contributes to the increase in coronary heart disease risk. Over the past 20 years, longitudinal studies of women traversing menopause have contributed significantly to our understanding of the relationship between the MT and CVD risk. By following women over this period, researchers have been able to disentangle chronological and ovarian aging with respect to CVD risk. These studies have documented distinct patterns of sex hormone changes, as well as adverse alterations in body composition, lipids and lipoproteins, and measures of vascular health over the MT, which can increase a woman's risk of developing CVD postmenopausally. The reported findings underline the significance of the MT as a time of accelerating CVD risk, thereby emphasizing the importance of monitoring women's health during midlife, a critical window for implementing early intervention strategies to reduce CVD risk. Notably, the 2011 American Heart Association guidelines for CVD prevention in women (the latest sex-specific guidelines to date) did not include information now available about the contribution of the MT to increased CVD in women. Therefore, there is a crucial need to discuss the contemporary literature on menopause and CVD risk with the intent of increasing awareness of the significant adverse cardiometabolic health-related changes accompanying midlife and the MT. This scientific statement provides an up-to-date synthesis of the existing data on the MT and how it relates to CVD.

Menstruation: science and society

Women's health concerns are generally underrepresented in basic and translational research, but reproductive health in particular has been hampered by a lack of understanding of basic uterine and menstrual physiology. Menstrual health is an integral part of overall health because between menarche and menopause, most women menstruate. Yet for tens of millions of women around the world, menstruation regularly and often catastrophically disrupts their physical, mental, and social well-being. Enhancing our understanding of the underlying phenomena involved in menstruation, abnormal uterine bleeding, and other menstruation-related disorders will move us closer to the goal of personalized care. Furthermore, a deeper mechanistic understanding of menstruation-a fast, scarless healing process in healthy individuals-will likely yield insights into a myriad of other diseases involving regulation of vascular function locally and systemically. We also recognize that many women now delay pregnancy and that there is an increasing desire for fertility and uterine preservation. In September 2018, the Gynecologic Health and Disease Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development convened a 2-day meeting, "Menstruation: Science and Society" with an aim to "identify gaps and opportunities in menstruation science and to raise awareness of the need for more research in this field." Experts in fields ranging from the evolutionary role of menstruation to basic endometrial biology (including omic analysis of the endometrium, stem cells and tissue engineering of the endometrium, endometrial microbiome, and abnormal uterine bleeding and fibroids) and translational medicine (imaging and sampling modalities, patient-focused analysis of menstrual disorders including abnormal uterine bleeding, smart technologies or applications and mobile health platforms) to societal challenges in health literacy and dissemination frameworks across different economic and cultural landscapes shared current state-of-the-art and future vision, incorporating the patient voice at the launch of the meeting. Here, we provide an enhanced meeting report with extensive up-to-date (as of submission) context, capturing the spectrum from how the basic processes of menstruation commence in response to progesterone withdrawal, through the role of tissue-resident and circulating stem and progenitor cells in monthly regeneration-and current gaps in knowledge on how dysregulation leads to abnormal uterine bleeding and other menstruation-related disorders such as adenomyosis, endometriosis, and fibroids-to the clinical challenges in diagnostics, treatment, and patient and societal education. We conclude with an overview of how the global agenda concerning menstruation, and specifically menstrual health and hygiene, are gaining momentum, ranging from increasing investment in addressing menstruation-related barriers facing girls in schools in low- to middle-income countries to the more recent "menstrual equity" and "period poverty" movements spreading across high-income countries.

Oxygen saturation during sleep as a predictor of inflammation in anovulatory women

PURPOSE

To evaluate the inflammatory profile of premenopausal women with anovulatory cycles, regular menstrual cycles, or using contraceptives, and the associations with sleep and health-related parameters.

METHODS

Subjects completed questionnaires including the Pittsburgh Sleep Quality Index and the Epworth sleepiness scale, underwent whole-night polysomnography, and had blood collected for analysis of inflammatory, cardiovascular, and hormonal parameters. Women of reproductive age were categorized into three groups for comparisons: anovulatory menstrual cycles, regular menstrual cycles, and hormonal contraceptive use.

RESULTS

Women with anovulatory menstrual cycles (n = 20) had higher circulating levels of the proinflammatory cytokine IL-6 compared with women who had regular menstrual cycles (n = 191) and those on hormonal contraception (n = 72). No other classical marker of low-grade inflammation was significantly different. Subjective and objective sleep data were similar among groups. However, the mean peripheral oxygen saturation (SpO2) during sleep was reduced in anovulatory women. The analysis of associated variables of the inflammatory profile demonstrated that mean SpO2 during sleep was a predictive factor of IL-6 levels.

CONCLUSIONS

Our data suggest that in premenopausal women with anovulation, a proinflammatory condition mediated by IL-6 is associated with lower oxygen levels during sleep. These findings reflect the balance between gynecological status, the immune system, and sleep, pointing to the need to control for these factors in clinical practice and research contexts.

Health-related quality of life and resilience in peri- and postmenopausal women during Covid-19 confinement

•

Physical activity and sexual activity are associated with high quality of life and high levels of resilience.

•

The use of antidepressants is associated with poor quality of life and low levels of resilience.

•

Quality of life was greater among women who lived with others during Covid-19 confinement.

•

Covid-19 status is not an independent factor for quality of life or resilience.

Objective

To assess the impact of confinement due to the coronavirus (Covid-19) pandemic on health-related quality of life (HRQoL) and resilience in peri- and postmenopausal women.

Material and Methods

We used an online questionnaire which was sent between April 30th and May 13th, 2020 to women aged 40–70 years who were peri- or postmenopausal according to STRAW criteria. We used the 16-item Cervantes short-form scale (Cervantes-SF) to measure HRQoL, and the 14-item Wagnild and Young Resilience Scale (RS-14) to measure resilience. High scores on the Cervantes-SF indicate low HRQoL and high scores on the RS-14 indicate high levels of resilience. Covid-19 status, sociodemographic descriptors, and lifestyle variables were also evaluated.

Results

We included 2430 peri- and postmenopausal women with valid questionnaires. All items of the Cervantes-SF were completed in 2151 cases, whilst the RS-14 was completed in 2413 cases. There was a negative correlation between scores on the Cervantes-SF and RS-14 scales (Rho -0.350; p < 0.0001). Multiple linear regression analysis revealed a statistically significant association between Cervantes-SF scores and living with others (β-coefficient -10.2; p < 0.001), use of antidepressants (β 9.3; p < 0.001), physical activity (β -8.6; p < 0.001) and sexual activity (β -2.7; p < 0.001). Resilience was associated with the use of antidepressants (β -5.9; p < 0.001), physical activity (β 3.2; p < 0.001) and sexual activity (β 1.7; p = 0.005). According to the multivariate analysis, there were no associations between either Covid-19 or menopausal status and HRQoL or resilience scores.

Conclusions

During the period of mandatory Covid-19 confinement, peri- and postmenopausal women who engaged in physical and sexual activity had higher HRQoL and higher levels of resilience, whilst women who were using antidepressants had lower HRQoL and lower levels of resilience. HRQoL was greater in women who lived with others.

Association Between Parity and the Age at Menopause and Menopausal Syndrome in Northwest China

This study evaluated the relationships between parity and the age at menopause and menopausal syndrome among Chinese women in Gansu. A total of 7236 women aged 40 to 55 years met study eligibility criteria. The modified Kupperman Menopausal Index scale was used to assess the severity of menopausal syndrome. Cox regression was applied to estimate hazard ratio and 95% confidence interval, and logistic regression was performed to calculate odds ratio and confidence interval. The mean age at menopause was 47.91 ± 3.31 years. There is no relationship between parity and age at menopause. Women with nulliparity or multiparity seemed to have higher risks of moderate and severe menopausal syndrome. The potential beneficial effects of one or two births on menopausal syndrome were also observed by applying the multivariable logistic regression analysis, particularly in urogenital symptoms. Women with nulliparity and multiparity appeared to be at the higher risks of menopause syndrome.

Changes in six domains of cognitive function with reproductive and chronological ageing and sex hormones: a longitudinal study in 2411 UK mid-life women

BACKGROUND

There may be changes in cognitive function in women going through the menopause. The current evidence remains unclear, however, whether these changes occur over and above those of general ageing. We aimed to evaluate the potential impact of the menopause (assessed by reproductive age and hormone levels) on cognitive function in women in mid-life accounting for the underlying effects of ageing.

METHODS

The study was based on the follow up of women originally enrolled in pregnancy in a birth cohort when resident in the South West of England, UK between 1991 and 1992. Using up to three repeated measurements in 2411 women (mean age 51 at first assessment), we modelled changes in six cognitive function domains: immediate and delayed verbal episodic memory, working memory, processing speed, verbal intelligence and verbal fluency. The exposures of interest were reproductive age measured as years relative to the final menstrual period (FMP), chronological age and reproductive hormones (follicle-stimulating hormone (FSH), luteinizing hormone (LH) and anti-Müllerian hormone (AMH)).

RESULTS

Processing speed (- 0.21 (95% CI - 0.36 to - 0.06) standard deviation (SD) difference per 10 years since FMP), immediate verbal episodic memory (- 0.15 (95% CI - 0.35 to 0.06)) and delayed verbal episodic memory (- 0.17 (95% CI - 0.37 to 0.03)) declined with reproductive age. Reproductive hormones were not robustly associated with processing speed, but FSH and LH were both negatively associated with immediate (- 0.08 (95% CI - 0.13 to - 0.02) SD difference per SD difference in hormone level) and delayed verbal episodic memory (- 0.08 (95% CI - 0.13 to - 0.03)). There was little consistent evidence of cognitive function declining with menopause in other cognitive domains.

CONCLUSIONS

Of the cognitive domains tested only verbal episodic memory declined both in relation to age since the menopause and in conjunction with the reproductive hormones that reflect the menopause. This decline was independent of normal ageing and suggests that the menopause is associated with a mild impact on this specific domain of cognitive function.

Association of snoring and body composition in (peri-post) menopausal women

BACKGROUND

Little attention has been paid to whether snoring frequency is associated with body composition in menopausal women, particularly in China. This study objected to investigate the association between self-reported snoring and body composition in (peri-post) menopausal Chinese women as well as metabolic indicators.

METHODS

This cross-sectional study enrolled 715 participants aged 40-67 years from the Menopause Clinic in the Shanghai Sixth People's Hospital. Participants were categorized into four subgroups stratified by self-reported snoring frequency: never, rarely (< 1 night per week), occasionally (1-2 nights per week), regularly (≥3 nights per week), while body composition was measured using bioelectrical impedance analysis (BIA). Besides, blood sample were collected to test the glycolipid indicators.

RESULTS

In our sample of investigation, regular snoring (≥3 nights per week) was found to be an independent risk factor for higher fat mass (total, upper limbs, trunk), with the highest risk of 2.4 times for fat mass of trunk after adjusting for metabolic confounders(p = 0.003). Meanwhile, regular snoring was independently associated with higher fat mass (total and each segment) only in menopausal transition (p = 0.023).

CONCLUSIONS

We suggested that self-reported regular snoring may be taken as a simple alternative to predict higher fat mass (≥17.11 kg, upper quartile) in menopausal women. Similarly, body composition should be attached to the great importance to those who in menopausal transition in order to help to prevent obstructive sleep apnea (OSA).

Inverse association between bone mineral density and fibrinogen in menopausal women

OBJECTIVE

Inflammatory diseases are risk factors for osteoporosis. We aimed to explore whether fibrinogen, which is linked to chronic inflammation, is associated with bone mineral density (BMD) in menopausal women.

METHODS

In this cross-sectional study, we analyzed 339 menopausal women from Zhejiang Province between January 2016 and October 2019. Linear regression analysis was performed to assess the relationship between fibrinogen and BMD.

RESULTS

Significant inverse association was observed between the serum fibrinogen level and BMD in menopausal women. The mean BMD in each quartile of fibrinogen level was 0.901, 0.897, 0.892, and 0.855 g/cm², respectively (p = 0.027). After adjusting for age, body mass index, metabolic profiles, blood inflammatory factors, and serum levels of estradiol, calcium, phosphorus, and alkaline phosphatase, fibrinogen levels remained significantly associated with BMD (regression coefficients for quartiles 1-3 vs. quartile 4 were 0.046, 0.027, and 0.036, respectively; p for trend <0.05).

CONCLUSIONS

Higher fibrinogen levels were associated with lower BMD in menopausal women, which was independent of age, body mass index, estradiol, and other factors. Therefore, serum fibrinogen can be used as a new predictor of reduced BMD in menopausal women.

Applicability of health promoting lifestyle profile-II for postmenopausal women in Sri Lanka; a validation study

BACKGROUND AND OBJECTIVE

Health Promoting Lifestyle Profile-II (HPLP-II), developed in the West, evaluates 52 health promoting behaviors (HPB) under six subscales. In this study we evaluated the applicability of HPLP-II to assess the HPB of postmenopausal women (PMW) conversant in the Sinhala language in Sri Lanka.

METHODS

The Sinhala version of HPLP-II was adapted following standard methodology of cross cultural adaptation. It included forward and backward translations, review by an expert group, focus group discussion and pre-testing. It was self-administered among randomly selected healthy, Sinhalese, community-dwelling PMW (n = 245, aged 55.9 ± 3.4 years), along with the Short Form 36 (SF-36) survey. The Sinhala version of HPLP-II was re-administered among a subsample (n = 105) after two weeks of first administration. Psychometric properties - reliability and validity, were evaluated.

RESULTS

In the Sinhala version of HPLP-II, both internal consistency (Cronbach's alpha = 0.98) and test-retest reliability (intra class correlation / ICC = 0.98, 95%CI = 0.97-0.99) were high. Structural validity assessment with Factor analysis using Principal Component Analysis extracted seven factors explaining 80.65% cumulative variance with few exceptions from the original version. Health responsibility (HR) and spiritual growth (SG) subscales of HPLP-II and physical and psychological health dimensions scores of SF-36 scores correlated significantly (r > 0.63, p < 0.001) ensuring strong concurrent validity.

CONCLUSIONS

The Sinhala version of HPLP-II adapted by us is a tool with high reliability and validity.

Aging Fits the Disease Criteria of the International Classification of Diseases

The disease criteria used by the World Health Organization (WHO) were applied to human biological aging in order to assess whether aging can be classified as a disease. These criteria were developed for the 11th revision of the International Classification of Diseases (ICD) and included disease diagnostics, mechanisms, course and outcomes, known interventions, and linkage to genetic and environmental factors. RESULTS: Biological aging can be diagnosed with frailty indices, functional, blood-based biomarkers. A number of major causal mechanisms of human aging involved in various organs have been described, such as inflammation, replicative cellular senescence, immune senescence, proteostasis failures, mitochondrial dysfunctions, fibrotic propensity, hormonal aging, body composition changes, etc. We identified a number of clinically proven interventions, as well as genetic and environmental factors of aging. Therefore, aging fits the ICD-11 criteria and can be considered a disease. Our proposal was submitted to the ICD-11 Joint Task force, and this led to the inclusion of the extension code for "Ageing-related" (XT9T) into the "Causality" section of the ICD-11. This might lead to greater focus on biological aging in global health policy and might provide for more opportunities for the new therapy developers.

Polymorphism of the THOC5 of the transcription/export multiprotein complex and its correlation with the lipid and metabolic profile in middle-aged women

The transcription/export complex (TREX) is formed by a core called THO. These are necessary for the transcription and packaging of messenger RNA and its subsequent nuclear exportation. Studies have correlated THO-specific polymorphisms with abnormalities of HDL-C metabolism. To correlate lipid and metabolic parameters with the genetic variants of the rs8135828 polymorphism of the THOC5 gene in middle-aged women. DNA was extracted from the whole blood of 183 women aged 40-65 and tested for the rs8135828 polymorphism of the THOC5 gene using real-time PCR. HDL-C, LDL-C, triglyceride, and total cholesterol levels, as well as other metabolic parameters, were correlated with the polymorphism genotypes: GG, AG, and AA. Mean age of women was 50.6 ± 6.3 years, 54.6% were postmenopausal and 16.4% had the metabolic syndrome. GG was the most frequently determined genotype (62.3%). There were no differences in lipid levels according to genotypes; although there was a trend for lower HDL-C levels for the AA and AG + AA genotypes. Those with the AG and AG + AA genotypes displayed significantly higher glucose levels (p = .02 and p = .002, respectively); with a trend toward a higher metabolic syndrome prevalence and increased abdominal perimeters in both variants (AG and AG + AA). The AG genotype was related to higher glucose levels but not with abnormal lipid parameters. There is a need for more research in this regard.

The efficacy and safety of acupuncture for perimenopause symptom compared with different sham acupuncture control groups: A protocol of systematic review and meta-analysis

BACKGROUND

Perimenopause is a period that every woman must go through, most people are more or less affected by perimenopausal symptoms, it to affect women's health, work, life, and economy. As acupuncture treatment is more and more increasing in perimenopausal symptoms, there have also been many clinical trials about it. But the results of the trials are inconsistent. Therefore, we will conduct a systematic review and meta-analysis of the safety and efficacy of perimenopausal symptoms treated with acupuncture.

METHODS

The protocol followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. RCT study on different acupuncture interventions for perimenopausal symptoms will be searched in 8 databases (PubMed, EMBASE, the Cochrane Library, the web of science, CBM, CNKI, WAN FANG, and VIP). Besides, the search will also be performed on the clinical trial research platform if necessary. The primary outcome that will be extracted: the Flushes per 24 hours, the Frequency of hot flashes, the severity of hot flashes, the menopause-related symptom score, the treatment efficacy, the adverse event. Endnote software X8 will be used for study selection, STATA 13.0 and Review Manager software 5.3 will be used for analysis and synthesis. These studies selection, data extraction, and risk of bias assessment will be conducted by 2 independent reviewers.

RESULTS

This study will provide the results: 1. the primary and secondary outcome indicators of different acupuncture intervention measures (traditional hand acupuncture, moxibustion, ear acupuncture, laser, acupressure points) for perimenopausal symptoms. 2. The effects of different control groups (medicine control, routine care, waiting, and sham acupuncture control) on the analysis results will be reported, especially the effects of different sham acupuncture control (invasive/noninvasive) on the analysis results.

CONCLUSION

This systematic review and meta-analysis study hopes to provide useful evidence for better use of different types of acupuncture in treat perimenopausal symptoms and better design of control groups in related clinical trials. In addition, the research conclusion will be published in peer journals.OSF REGISTRATION NUMBER DOI 10.17605/OSF.IO/VZCKU Ethics and dissemination This conclusion of the study will be published in peer journals. The ethical approval is not required because there is no direct involvement of human.

Depression during perimenopause: the role of the obstetrician-gynecologist

Depression in women is more common during perimenopause (the transition to menopause) than at other times in the life cycle. Symptoms of depression may be different in perimenopausal women compared to younger or older women, and are often dismissed as part of normal menopause. This is an expert narrative review. There are several evidence-based screening modalities which can be integrated into routine women's health visits, and can facilitate distinguishing between depression and normal perimenopausal symptoms. There is emerging evidence regarding the effect of hormonal changes on the development of perimenopausal depression and its optimal treatment, though critical research gaps remain. Obstetrician-gynecologists and other primary care providers play a vital role in the detection and management of depression in women. Providers caring for women during perimenopause have a unique opportunity to diagnose depression in their patients and identify appropriate treatment options.

Hormonal Biophysiology of the Uterus

Intrauterine development of the uterus is promoted by the hormonal influence of the maternal steroid sex hormones on the female fetus. The cyclic activity of the endometrium starts at puberty, at menarche, and is controlled by the pituitary hormones (FSH and LH) and steroid ovarian hormones, the latter acting on the target tissue-the endometrium. The proliferative and secretory cyclic changes of the endometrium prepare the uterus for implantation of a fertilized ovum. Ovarian failure to secrete steroid hormones results in the menopausal gradual atrophy of the endometrium.

Clinical Research of the Application of Bone Turnover Markers in Monitoring the Short-Term Therapeutic Efficacy of Vitamin D in Postmenopausal Osteoporotic women in Harbin, China

BACKGROUND

The incidence of osteoporosis (OP) is increasing year by year. researches have shown that there was an intense link between the vitamin D (VitD) status and the efficacy of zoledronate (ZOL) in patients with osteoporosis. Since VitD is related to the geogen, its promotion effect on zoledronate has regional specificity.

AIM

Combining dual-energy X-ray and bone turnover markers (BTM) to explore the VitD level in postmenopausal osteoporosis patients in Harbin and monitor its effect on the anti-osteoporosis effect of ZOL.

METHODS

A total of 120 patients with postmenopausal osteoporosis (PMO) were enrolled .These patients were divided into two groups with 25(OH)D levels = 10ng/ml as a critical point, and each group was randomly divided into experimental groups and control groups). All of the patients were conducted 5 mg ZOL. Then the experimental group was given calcitriol and calcium carbonate, and the control group was only given calcium carbonate. BTM were measured at baseline, 24h, 3 months and 6 months. We also measured bone mineral density (BMD) of bilateral hips (TH BMD) and lumbar spine (LS BMD) at baseline and 6 months.

RESULTS

The VitD deficiency rates of the patients enrolled were 84.1%. There was an inverse relationship between the baseline level of VitD and the serum levels of P1NP / β-CTX, (r=-0.452,p=0.00; r=-0.225, p=0.01). Comparing with baseline, the level of serum P1NP,β-CTX in each group declined significantly after the treatment (P<0.05). The mean decreasing rates of P1NP and β-CTX in the both experimental groups were significantly higher than that of the corresponding control groups at the same time point (P<0.05), after 6 months of medication. Both TH BMD and LS BMD at 6 months increased significantly. The increase rate of LS BMD in the high VitD experimental group was significantly higher than the other three groups (P<0.05), the increase rates of TH BMD in the low VitD control group were significantly lower than the other three groups (P<0.05).

CONCLUSIONS

The levels of serum VitD in the patients enrolled in this study were generally low. VitD could increase the therapeutic effect of ZOL on osteoporosis.

Plasma Cytokine Levels in Overweight Versus Obese Disease-Free Perimenopausal Women

OBJECTIVE

To evaluate the plasma cytokine levels during T cell-mediated inflammatory responses and compare the metabolic markers between overweight and obese perimenopausal women without systemic diseases.

METHODS

Sixty perimenopausal women were divided into two groups (overweight and obese). Participants in both groups had their waist-to-height ratio (WHtR) measured and blood samples collected for the evaluation of estradiol, fasting glucose, leptin, high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, IL-10, IL-17A levels, and lipid profile.

RESULTS

In univariate analysis, women with obesity showed increased WHtR, fasting glucose, leptin, and IL-6 (p < 0.05) levels; however, significant differences were not observed in IL-10 or IL-17A (p > 0.05) levels. In the receiver operating characteristic curve, the highest areas under the curve were shown for leptin (0.856) and IL-6 (0.706). IL-6 levels correlated with both hs-CRP (r = 0.302, p = 0.020) and leptin (r = 0.294, p = 0.022). However, in multivariate analysis, IL-6 was not associated with a greater likelihood of obesity (OR = 1.61; 95% CI: 0.82-3.15; p = 0.16), when potential confounders were considered.

CONCLUSION

IL-6 levels varied between overweight and obese perimenopausal women, and this association was weaker when adjusted for other clinical variables.

Intramyocardial Triglycerides Among Women With vs Without HIV: Hormonal Correlates and Functional Consequences

CONTEXT

Women with HIV (WHIV) on anti-retroviral therapy (ART) are living longer but facing heightened vulnerability to heart failure.

OBJECTIVE

We investigated metabolic/hormonal/immune parameters relating to diastolic dysfunction-a precursor to heart failure-among WHIV without known cardiovascular disease (CVD).

DESIGN AND OUTCOME MEASURES

Nineteen ART-treated WHIV and 11 non-HIV-infected women without known CVD enrolled and successfully completed relevant study procedures [cardiac magnetic resonance spectroscopy (MRS) and cardiac MRI]. Groups were matched on age and body mass index. Primary outcome measures included intramyocardial triglyceride content (cardiac MRS) and diastolic function (cardiac MRI). Relationships between intramyocardial triglyceride content and clinical parameters were also assessed.

RESULTS

Among WHIV (vs non-HIV-infected women), intramyocardial triglyceride content was threefold higher [1.2 (0.4, 3.1) vs 0.4 (0.1, 0.5)%, P = 0.01], and diastolic function was reduced (left atrial passive ejection fraction: 27.2 ± 9.6 vs 35.9 ± 6.4%, P = 0.007). There was a strong inverse relationship between intramyocardial triglyceride content and diastolic function (ρ = -0.62, P = 0.004). Among the whole group, intramyocardial triglyceride content did not relate to chronologic age but did increase across the reproductive aging spectrum (P = 0.02). HIV status and reproductive aging status remained independent predictors of intramyocardial triglyceride content after adjusting for relevant cardiometabolic parameters (overall model R2 = 0.56, P = 0.003; HIV status P = 0.01, reproductive aging status P = 0.02).

CONCLUSIONS

For asymptomatic WHIV, increased intramyocardial triglyceride content is associated with diastolic dysfunction. Moreover, relationships between intramyocardial triglyceride accumulation and women's reproductive aging are noted.

Hormonal, metabolic and inflammatory circulating biomarker profiles in obese and non-obese Brazilian middle-aged women

AIM

To investigate circulating hormonal, metabolic and inflammatory biomarker profiles in obese and non-obese middle-aged women.

METHODS

A total of 110 women, aged 40-60 years, were included in this cross-sectional study. Patients were allocated, according to the occurrence of menopause and body mass index (BMI), into four groups: PM0 (premenopausal non-obese), PM1 (premenopausal obese), M0 (postmenopausal non-obese), and M1 (postmenopausal obese). Serum levels of gonadotropins, sex hormones, lipid markers, leptin, hs-CRP and interleukin-6 were obtained using either colorimetric or immunoenzymatic assays. Univariate and correlation analyses were performed among all clinical and laboratorial parameters. Principal component analysis was used to characterize subsets of biomarkers, which had their discriminatory capacity tested using discriminant function analysis.

RESULTS

Levels of gonadotropins and female sex hormones were similar between PM0 and PM1 and between M0 and M1 (p > 0.05), all of them varied between PM0 and M0 (p < 0.05), but only estradiol was significantly altered in the comparison between PM1 and M1 (p = 0.027). Regarding metabolic markers, leptin was lower in PM0 than in M0 (p = 0.010) and higher in M1 than in M0 (p = 0.046). In premenopausal women, BMI correlated only to leptin, while it correlated to several other markers in postmenopausal women. A combination of FSH and leptin serum levels significantly discriminated the four groups (Wilks's lambda < 0.001, in canonical functions 1 and 2).

CONCLUSION

A combined analysis of hormonal biomarkers may potentially distinguish obese from non-obese women with distinct menopause status. Further research is thus required to clarify the clinical significance of such findings.

Ankle kinematics and kinetics during gait in healthy and rheumatoid arthritis post-menopausal women

Objective: In the literature, it is not clear whether rheumatoid arthritis (RA) post-menopausal women have different ankle biomechanical parameters than healthy post-menopausal women. This study aimed to compare the ankle kinematics and kinetics during the gait stance phase of RA post-menopausal women with age-matched healthy post-menopausal women. Materials and methods: A three-dimensional motion analysis system (9 cameras; 200 Hz) synchronised with a force plate (1000 Hz) was used to assess ankle kinematics and kinetics during barefoot walking at a natural and self-selected speed. A biomechanical model was used to model body segments and joint centres (combined anthropometric measurements and the placement of 39 reflective markers). Thirty-six women (18 RA post-menopausal women and 18 age-matched healthy post-menopausal women) performed 14 valid trials (comprising seven left and seven right footsteps on a force plate). Lower limb muscle mass was evaluated by an octopolar bioimpedance analyser. Results: RA post-menopausal women yielded a longer stance phase and controlled dorsiflexion sub-phase (p < 0.001), higher dorsiflexion at the final controlled dorsiflexion sub-phase and lower plantar flexion at toe off (p < 0.05), lower angular displacements (p < 0.05), and lower ankle moment of force peak and ankle power peak (p < 0.001). No intergroup differences were found in lower limb muscle mass. Conclusions: RA post-menopausal women yielded changes in ankle kinematic and kinetic parameters during the gait stance phase, resulting in a lower capacity to produce ankle moment of force and ankle power during the propulsive gait phase.

'Age of despair', or 'when life starts': migrant and refugee women negotiate constructions of menopause

There has been a call for research on migrant and refugee women's negotiation of diverse discourses and cultural constraints associated with sexual embodiment, including menopause, in order to facilitate sexual and reproductive health and understand gendered subjectivity. This study examined the construction and experience of menopause among migrant and refugee women who had settled in Australia or Canada in the last 10 years. Eighty-four individual interviews and 16 focus groups comprising 85 participants were conducted (total n = 169), with women aged 18 years and over from Afghanistan, India (Punjab), Iraq, Somalia, South Sudan, Sri-Lanka (Tamil), Sudan and various South American (Latina) backgrounds. Thematic decomposition identified three discursive themes: Menopause as the Age of Despair; a Discourse of Silence and Secrecy; and Menopause as a Life Stage - or when Life Starts. Negative constructions of menopause, associated with silence and secrecy, were evident across different cultural groups, with implications for women's positioning and experience of menopausal change and embodiment. However, resistance to negative discourse was also evident. This was primarily associated with having received menopause education and more open communication about menopausal change, suggesting that education and health information can facilitate affirming aspects of menopause.
