Associations of depression with the transition to menopause

The impact of resistance training on memory, gait and oxidative stress during periestropause in rats

Aging, especially in female, is complex, involving various factors such as reproductive sensitivity, cognitive and functional decline, and an imbalance in the redox system. This study aims to assess the effectiveness of long-term resistance training as a non-pharmacological strategy to mitigate the impairment of recognition memory, hippocampal redox state, and ambulation in aging female Wistar rats during the periestropause period. Thirty Wistar rats aged 17 months, in periestropause, were distributed into non-trained (NT) and resistance training (RT; stair climbing 3 times per week for 4 months) groups. Before (17 months) and after (21 months) of the RT period, the rats underwent tests for ambulation, elevated plus maze (EPM), open field, and object recognition. Biochemical and histological analyses were conducted on the hippocampus of these animals. Analysis of the results revealed that at 21 months, females in the NT group (21Mo/NT) exhibited a decreased in length (p=0.0458) and an increased in past width (p<0.0479) compared to their measurements at 17 months. However, after 4 months of RT, the female rats aged 21 months (21Mo/RT group) experienced changes in gait components, showing an increase in length (p<0.0008) and a decrease in stride width. Regarding memory, the object recognition test indicated potential cognitive improvement in 21Mo/RT animals, with significant interaction between intervention and age across all three stages of the test (total exploration time, p=0.0001; Test 1, p=0.0003; Test 2, p=0.0014). This response was notable compared to animals in the 21Mo/NT group, which showed a decline in memory capacity (p<0.01). The data showed a significant difference in relation to the age of the animals (p<0.01). The hippocampal redox state markers showed reduced lipid oxidative (p=0.028), catalase (p=0.022), and superoxide dismutase (p=0.0067) in the RT group compared to the NT group. Hippocampal cells from the 21Mo/RT group showed increased citrate synthase enzyme activity (p<0.05) and Nissl body staining (p<0.05). The results of this study demonstrate that RT performed during the periestropause phase leads to significant improvements in functional abilities, cognitive performance, and neuroplasticity in aging female rats.

Early-onset vasomotor symptoms and development of depressive symptoms among premenopausal women

BACKGROUND

We investigated the association between vasomotor symptoms (VMSs) and the onset of depressive symptoms among premenopausal women.

METHODS

This cross-sectional study included 4376 premenopausal women aged 42-52 years, and the cohort study included 2832 women without clinically relevant depressive symptoms at baseline. VMSs included the symptoms of hot flashes and night sweats. Depressive symptoms were evaluated using the Center for Epidemiological Studies Depression Scale; a score of ≥16 was considered to define clinically relevant depressive symptoms.

RESULTS

Premenopausal Women with VMSs at baseline exhibited a higher prevalence of depressive symptoms compared with women without VMSs at baseline (multivariable-adjusted prevalence ratio 1.76, 95 % confidence interval [CI] 1.47-2.11). Among the 2832 women followed up (median, 6.1 years), 406 developed clinically relevant depressive symptoms. Women with versus without VMSs had a significantly higher risk of developing clinically relevant depressive symptoms (multivariable-adjusted hazard ratio, 1.72; 95 % CI 1.39-2.14). VMS severity exhibited a dose-response relationship with depressive symptoms (P for trend <0.05).

LIMITATIONS

Self-reported questionnaires were only used to obtain VMSs and depressive symptoms, which could have led to misclassification. We also could not directly measure sex hormone levels.

CONCLUSIONS

Even in the premenopausal stage, women who experience hot flashes or night sweats have an increased risk of present and developed clinically relevant depressive symptoms. It is important to conduct mental health screenings and provide appropriate support to middle-aged women who experience early-onset VMSs.

Chronic stress, social support, and symptoms at midlife. Is there a buffering effect?

OBJECTIVES

This study was designed to examine associations among measures of stress, social support, and symptoms at midlife. Specifically, the study examined whether support buffered against the negative effects of stress on severity of symptoms grouped via factor analyses into emotional instability, vaso-somatic symptoms, mood disturbances, and aches and pains.

METHODS

We used cross-sectional data from n = 119 women aged 40-55 in Nagaland, India. Midlife symptoms were measured with the help of questionnaires, and factor analysis was used to identify latent factors. Stress and social support were measured by Perceived Stress Scale and Multidimensional Scale of Perceived Social Support, respectively. Chronic stress was measured by fingernail cortisol.

RESULTS

After adjusting for menopausal status, tobacco use, body mass index, and socioeconomic status, cortisol level was positively associated with emotional instability (p < 0.01), vaso-somatic symptom score (p < 0.05), and total symptoms at midlife (p < 0.05). Familial support was negatively associated with emotional instability (p < 0.05) and total symptoms at midlife (p < 0.05). However, no significant associations were observed with spousal or friend support. Although no significant interactions between stress, social support, and symptoms at midlife were observed, spousal support when stratified as high and low support using the means, perceived stress and vaso-somatic symptoms indicated an interaction.

CONCLUSION

Cortisol level and support from family were independently associated with symptoms at midlife. The study highlights the importance of family ties and support for navigating the stressors of everyday life among women in Nagaland.

Effect of Physical Exercise on Executive Functions Using the Emotional Stroop Task in Perimenopausal Women: A Pilot Study

Exercise has beneficial effects on emotional cognitive control for the majority of the population. However, the impact of exercise on cognitive processes in perimenopausal women remains unclear. Therefore, this study investigated the effect of aerobic exercise on the cognitive processes of perimenopausal women using an emotional Stroop task (EST).

METHOD

A quasi-experimental pilot study was conducted involving 14 perimenopausal women (Peri-MG) and 13 healthy young women (YG) who completed an EST before and after an aerobic cycling exercise. Mixed-effects models for repeated measures were used to analyze reaction times (RTs) and error rates (ERs) during emotional word processing (positive, negative, and neutral) for both groups.

RESULTS

Compared with the YG, the Peri-MG showed significantly shortened RTs for positive and negative emotions (p < 0.05) post-exercise, but not for neutral words. In addition, the Peri-MG exhibited significantly increased ERs for negative words at baseline compared with the YG (p < 0.05), but this difference was not observed during the post-exercise test.

CONCLUSION

The findings suggest that aerobic exercise can enhance executive control performance in perimenopausal women. The Peri-MG exhibited marked behavioral plasticity in the form of reduced bias to salient cues that were significantly more sensitive to alterations due to exercise. This new evidence enhances the understanding of emotional vulnerability and beneficial susceptibility to exercise in perimenopausal women.

Prevalence of poor body image and its correlation with self-esteem and depression in middle-aged women

OBJECTIVE

This study aimed to determine the prevalence and predictors of poor body image and its influence on low self-esteem and depression in middle-aged women.

METHODS

The study was a cross-sectional survey of 372 women using a predesigned online questionnaire. Main outcome measures were mean scores on the nine-point body image scale (BIS) and prevalence of poor body image (BIS ≥ 10). Significant sociodemographic, physical and mental health predictors of BIS ≥ 10 were established using logistic regression analysis. Correlation of body image with self-esteem, assessed by Rosenberg's self-esteem scale, and depression, assessed by Beck's Depression Inventory, was established using Pearson's correlation coefficient and the odds ratios were determined using logistic regression analysis.

RESULTS

The mean scores obtained for body image were 5.52 (standard deviation 4.82) and the prevalence of BIS ≥ 10 was 17.4%. Significant predictors of poor body image were education status (0.59, 95% confidence interval [CI] = 0.39-0.89), body mass index (2.26, 95% CI = 1.12-4.55), social support structure (0.35, 95% CI = 0.16-0.79), diagnosis of mental illness (3.74, 95% CI = 1.31-10.66) and perception of menopause (positive vs. negative: 0.20, 95% CI = 0.07-0.55). Body image scores correlated with self-esteem (r = -0.46; 95% CI = -0.54 to -0.38) and depression (r = 0.59; 95% CI = 0.52-0.65). BIS ≥ 10 significantly increased the odds of low self-esteem (5.71; 95% CI = 2.66-12.26) and depression (11.25; 95% CI = 4.9-27.7).

CONCLUSIONS

The prevalence of poor body image in middle-aged women was 17.4%. This strongly correlated with low self-esteem and depression. A lower education status, higher body mass index, a negative perception of menopause, poor social support structure and a history of mental health diagnosis increased the odds of poor body image prevalence in middle-aged women.

Does a program-based cognitive behavioral therapy affect insomnia and depression in menopausal women? A randomized controlled trial

BACKGROUND

Menopausal women often complain of a range of physical and psychological symptoms known as menopausal syndrome. These symptoms are associated with fluctuating hormone levels, sleep disturbances, and mood swings.

AIM

This study aimed to examine the efficacy of a program-based cognitive behavioral group therapy (CBT) for insomnia and depression among women experiencing menopause.

METHODS

A randomized controlled trial of 88 women experiencing menopause was conducted in Egypt from June to September 2022 in outpatient clinics at Mansoura University Hospitals in Egypt. Participants were randomly assigned to a control group (45 women) and an intervention group (43 women). The intervention group received 7 weeks of CBT sessions. Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Beck Depression Inventory 2nd Edition (BDI-II) were administered before and after the intervention.

RESULTS

In the intervention group, there was a significant difference in scores of the subdomains of PSQI, including sleep efficiency, daytime dysfunction, subjective sleep quality, and sleep disturbance (t = 8.911, 11.77, 7.638, and 11.054, respectively), while no significant difference in domains of using sleep medication, sleep duration, and sleep latency. Significant improvements were observed between pre-and-post-intervention in the intervention group for the total scores of PSQI, ISI, and BDII-II (t = 12.711, 16.272, and 12.384, respectively), indicating a large effect size for the three studied variables (r = .81, .87, .8, respectively).

LINKING EVIDENCE TO ACTION

This study demonstrated the efficacy of group CBT for lowering insomnia and depression in women experiencing menopause. Thus, results indicated the need of considering prompt and appropriate interventions such as CBT as a safe treatment option to prevent the aggravation of sleep and emotional problems for menopausal women.

Obstetric and psychiatric history as predictors for psychosomatic symptoms among Korean perimenopausal women

OBJECTIVES

Menopause presents various physical and psychological disturbances for women and comes at a high financial cost. Therefore, this study aimed to identify factors influencing menopause symptoms.

STUDY DESIGN

Data of Korean perimenopausal women aged 40-60 (n = 1060; mean age, 46.03 ± 4.08) were collected by a research company. Participants were classified into a "functional" group (n = 716) or a "dysfunctional" group (n = 344) according to the severity of their perimenopausal psychosomatic symptoms. To investigate the association of obstetric and psychiatric history with membership of the "dysfunctional" group, a hierarchical logistic regression analysis was conducted.

RESULTS

The outcomes of all three hierarchical logistic regression models presented significant overall model fit. Among the independent variables, family history of menopausal symptoms, menarcheal age, number of pregnancies, history of postpartum depression, postpartum psychosis, and other psychiatric disorders were positively associated with being in the "dysfunctional" group, whereas age and number of deliveries were negatively associated with being in the "dysfunctional" group.

CONCLUSION

A short reproductive period and short exposure to estrogen due to late menarche and early menopausal transition may be related to severe perimenopausal symptoms. The relationship between the history of postpartum mental illness and severe perimenopausal symptoms may be associated with heightened sensitivity to hormonal triggers when a woman is exposed to fluctuating ovarian sex steroid levels. The relationship between parity or gravidity and the severity of menopausal symptoms in Korean women differed from that in studies conducted in other countries, possibly due to the low birth rate in Korea.

Diet and Depression during Peri- and Post-Menopause: A Scoping Review Protocol

The aim of the proposed scoping review is to describe and summarize studies assessing the associations between diet-related variables and depression in peri- and post-menopausal women. Studies examining the associations between diet-related variables and mental health indicators in women undergoing menopausal transition or in the post-menopausal period will be systematically retrieved via Medline, EMBASE, PsycINFO, Web of Science, and Scopus databases. All articles identified through the database searches will be imported into Covidence. Following the removal of duplicates, two authors will independently perform title and abstract screening, as well as full-text assessment against eligibility criteria. Data will be extracted using tables developed for observational and experimental studies. The methodological quality of randomized trials, cohort and cross-sectional studies, and case-control studies, will be assessed using the Cochrane risk-of-bias (RoB-2) tool, the NHLBI Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, and the NHLBI Quality Assessment Tool for Case-Control studies, respectively. Data extraction tables will be used to produce two tables summarizing the main characteristics and findings of the studies included in the review. In the proposed review, we will systematically identify and summarize the currently available evidence on the association between diet-related variables and depression in peri- and post-menopausal women. To our knowledge, this is the first review focusing on this subgroup of the population. Protocol registration: osf.io/b89r6.

Menopause-Biology, consequences, supportive care, and therapeutic options

Menopause is the cessation of ovarian function, with loss of reproductive hormone production and irreversible loss of fertility. It is a natural part of reproductive aging. The physiology of the menopause is complex and incompletely understood. Globally, menopause occurs around the age of 49 years, with geographic and ethnic variation. The hormonal changes of the menopause transition may result in both symptoms and long-term systemic effects, predominantly adverse effects on cardiometabolic and musculoskeletal health. The most effective treatment for bothersome menopausal symptoms is evidence-based, menopausal hormone therapy (MHT), which reduces bone loss and may have cardiometabolic benefits. Evidence-based non-hormonal interventions are also available for symptom relief. Treatment should be individualized with shared decision-making. Most MHT regimens are not regulator approved for perimenopausal women. Studies that include perimenopausal women are needed to determine the efficacy and safety of treatment options. Further research is crucial to improve menopause care, along with research to guide policy and clinical practice.

Impact of COVID-19 on health of menopausal women: A scoping review

OBJECTIVE

This scoping review aims to map and summarize the direct impact of contracting COVID-19, and the indirect consequences of the pandemic on the health of peri- and postmenopausal women.

METHODS

Searches for published studies were conducted in CINAHL, Cochrane, EMBASE, PubMed, Scopus, Web of Science, PsycINFO and ProQuest from inception to 26 Oct, 2022. Grey literature and reference lists of included studies were searched. Results are presented as a narrative synthesis and tables.

RESULTS

Thirty-eight studies were selected in this review. Overall, a majority of studies (n = 31) suggest that menopausal women were negatively impacted, while lesser studies (n = 21) concluded that they were not and some studies (n = 14) produced both negative and neutral results. Twenty-three studies presented on the direct health impact of COVID-19 infections on menopausal women. Eleven studies focused on the indirect impact of COVID-19 in terms of contact restriction measures on menopausal health during the pandemic compared to before the pandemic. Six studies described the different indirect impact of COVID-19 on health of menopausal women with various characteristics or lifestyles.

CONCLUSION

The direct and indirect impacts of COVID-19 on menopausal women on physical, mental health and social wellbeing are largely negative.

Sleep-light interventions that shift melatonin rhythms earlier improve perimenopausal and postmenopausal depression: preliminary findings

OBJECTIVE

Testing the hypothesis that a sleep-light intervention, which phase-advances melatonin rhythms, will improve perimenopausal-postmenopausal (P-M; by follicle-stimulating hormone) depression.

METHODS

In at-home environments, we compared two contrasting interventions: (1) an active phase-advance intervention: one night of advanced/restricted sleep from 9 pm to 1 am , followed by 8 weeks of morning bright white light for 60 min/d within 30 minutes of awakening, and (2) a control phase-delay intervention: one night of delayed/restricted sleep (sleep from 3 to 7 am ) followed by 8 weeks of evening bright white light for 60 min/d within 90 minutes of bedtime. We tested 17 P-M participants, 9 normal controls and 8 depressed participants (DPs) (by Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition] criteria). Clinicians assessed mood by structured interviews and subjective mood ratings. Participants wore actigraphs to measure sleep and activity and collected overnight urine samples for the melatonin metabolite, 6-sulfatoxymelatonin (6-SMT), before, during, and after interventions.

RESULTS

Baseline depressed mood correlated with delayed 6-SMT offset time (cessation of melatonin metabolite [6-SMT] secretion) ( r = +0.733, P = 0.038). After phase-advance intervention versus phase-delay intervention, 6-SMT offset (start of melatonin and 6-SMT decrease) was significantly advanced in DPs (mean ± SD, 2 h 15 min ± 12 min; P = 0.042); advance in 6-SMT acrophase (time of maximum melatonin and 6-SMT secretion) correlated positively with mood improvement ( r = +0.978, P = 0.001). Mood improved (+70%, P = 0.007) by both 2 and 8 weeks.

CONCLUSIONS

These preliminary findings reveal significantly phase-delayed melatonin rhythms in DP versus normal control P-M women. Phase-advancing melatonin rhythms improves mood in association with melatonin advance. Thus, sleep-light interventions may potentially offer safe, rapid, nonpharmaceutical, well-tolerated, affordable home treatments for P-M depression.

Altered resting-state hippocampal functional connectivity in breast cancer survivors with chemotherapy-induced amenorrhea

INTRODUCTION

Amenorrhea induced decrease of hormones is associated with cognitive impairment. This study aimed to evaluate hippocampal functional connectivity patterns in chemotherapy-induced amenorrhea (CIA) breast cancer (BC) patients, to evaluate the relationship between the functional connectivity features and hormone levels.

METHOD

Neuropsychological test, functional magnetic resonance imaging, and assessment of hormone levels were conducted in 21 premenopausal BC patients before chemotherapy (t0 ) and 1 week after completing chemotherapy (t1 ). Twenty matched healthy controls (HC) were also included and underwent the same assessments at similar time intervals. Mixed effect analysis and paired t-test were used to compare differences in brain functional connectivity.

RESULTS

Voxel-based paired t-tests revealed increased functional connectivity of the right and left hippocampus with the left fusiform gyrus, inferior and middle temporal gyrus, inferior occipital gyrus, left lingual gyrus, and parahippocampal gyrus after chemotherapy (p < .001) in CIA patients. Repeated measures analysis revealed significant group-by-time interactions in the left hippocampus with the bilateral fusiform gyrus, right parahippocampal gyrus, left inferior temporal gyrus, and left inferior occipital gyrus (p < .001). Premenopausal BC patients had no significant differences in cognitive function compared with HC at baseline. However, the CIA patients had high levels of self-rating depression scale, self-rating anxiety scale, total cholesterol, and triglycerides. Further, the CIA patients showed significant differences in hormone and fasting plasma glucose levels and cognitive performances between t0 and t1 (p < .05). Functional connectivity changes between the left hippocampus and the left inferior occipital gyrus was negatively correlated with E2 and luteinizing hormone changes (p < .05).

CONCLUSION

The CIA patients had cognitive dysfunction mainly in memory and visual mobility. Chemotherapy may affect hippocampal-posterior cortical circuit which mediates visual processing in CIA patients. Moreover, E2 may be involved in this process.

Psychiatric aspects of ophthalmic disorders: A narrative review

Ophthalmic disorders have psychiatric aspects associated with them at various levels. Psychological factors have a well-documented role in the causation, aggravation, and maintenance of various ophthalmic conditions, including glaucoma, central serous retinopathy, dry eye disease, and retinitis pigmentosa. Many ophthalmic conditions, including blindness, have psychological manifestations as well, which need to be addressed, in addition to the ophthalmic pathology. There is also significant overlap in the treatment of the two disciplines in many ways. For instance, many ophthalmic drugs have psychiatric side effects. Even ophthalmological surgeries have psychiatric aspects associated with them, which primarily include black patch psychosis and anxiety in the operation theater. This review will be useful for psychiatrists and ophthalmologists, for their clinical practice and research. Future research should focus on this interface to give it its well-deserved attention.

P4 Medicine for Heterogeneity of Dry Eye: A Mobile Health-based Digital Cohort Study

During the 5th Science, Technology, and Innovation Basic Plan, the Japanese government proposed a novel societal concept -Society 5.0- that promoted a healthcare system characterized by its capability to provide unintrusive, predictive, longitudinal care through the integration of cyber and physical space. The role of Society 5.0 in managing our quality of vision will become more important in the modern digitalized and aging society, both of which are known risk factors for developing dry eye. Dry eye is the most common ocular surface disease encountered in Japan with symptoms including increased dryness, eye discomfort, and decreased visual acuity. Owing to its complexity, implementation of P4 (predictive, preventive, personalized, participatory) medicine in managing dry eye requires a comprehensive understanding of its pathology, as well as a strategy to visualize and stratify its risk factors. Using DryEyeRhythm®, a mobile health (mHealth) smartphone software (app), we established a route to collect holistic medical big data on dry eye, such as the subjective symptoms and lifestyle data for each individual. The studies to date aided in determining the risk factors for severe dry eye, the association between major depressive disorder and dry eye exacerbation, eye drop treatment adherence, app-based stratification algorithms based on symptomology, blink detection biosensoring as a dry eye-related digital phenotype, and effectiveness of app-based dry eye diagnosis support compared to traditional methods. These results contribute to elucidating disease pathophysiology and promoting preventive and effective measures to counteract dry eye through mHealth.

Systems biology of human aging: A Fibonacci time series model

Fractals are everywhere in nature, particularly at the interfaces where matter or energy must be transferred, since they maximize surface area while minimizing energy losses. Temporal fractals have been well studied at micro scales in human biology, but have received comparatively little attention at broader macro scales. In this paper, we describe a fractal time series model of human aging from a systems biology perspective. This model examines how intrinsic aging rates are shaped by entropy and Fibonacci fractal dynamics, with implications for the emergence of key life cycle traits. This proposition is supported by research findings. The finding of an intrinsic aging rate rooted in Fibonacci fractal dynamics represents a new predictive paradigm in evolutionary biology.

Estrogen fluctuations during the menopausal transition are a risk factor for depressive disorders

Women are significantly more likely to develop depression than men. Fluctuations in the ovarian estrogen hormone levels are closely linked with women's well-being. This narrative review discusses the available knowledge on the role of estrogen in modulating brain function and the correlation between changes in estrogen levels and the development of depression. Equally discussed are the possible mechanisms underlying these effects, including the role of estrogen in modulating brain-derived neurotrophic factor activity, serotonin neurotransmission, as well as the induction of inflammatory response and changes in metabolic activity, are discussed.

Factors associated with the high susceptibility to depression of women during the perimenopause

OBJECTIVE

This study investigated the factors associated with the high susceptibility of perimenopausal women to depression.

METHODS

A total of 66 perimenopausal women participated in this study. The Zung self-rating depression scale (SDS) was used to evaluate the intensity of depressive symptoms. The modified Kupperman index (KI) was used to assess common perimenopausal symptoms. Psychosocial factors were assessed via the Eysenck Personality Questionnaire, attitudes toward menopause checklist, and metacognition questionnaire (MCQ). Levels of serum estradiol, testosterone, and progesterone were determined.

RESULTS

There were statistically significant associations between SDS standard score and the KI scale score (β = .361, p = .001), years of education (β = -.309, p = .005), and F3 cognitive self-consciousness score of MCQ (β = -.234, p = .032; adjusted R²  = .264, F = 8.759, p < .001).

CONCLUSIONS

High susceptibility to depression of perimenopausal women may be related to lower educational level, more severe perimenopausal symptoms, and altered metacognition.

Nocturnal Hot Flashes, but Not Serum Hormone Concentrations, as a Predictor of Insomnia in Menopausal Women: Results from the Midlife Women's Health Study

Background: Sleep disruptions are among the most common symptoms experienced during menopause and can be associated with depression, hot flashes, and fluctuating hormones. However, few studies have examined how such risk factors influence sleep in midlife women in a network-based approach that will establish the complex relationship between variables. Materials and Methods: We used a Bayesian network (BN) to examine the relationship between multiple factors known to influence sleep and depression in midlife women, including hormone concentrations, hot flashes, and menopause status among participants of the longitudinal Midlife Women's Health Study. In year 1, 762 women (45-54 years of age) answered questions regarding the frequency of insomnia, hot flashes, and depression; 389 of the same women answered similar questions at year 4. We measured serum hormones and calculated free estradiol index, free testosterone index, and ratios of estradiol:progesterone, and estradiol:testosterone. For our model, we calculated the change in frequency of insomnia, depression, and covariates (body mass index, menopause status, hot flashes at night, and present quality of life) from year 1 to 4. Results: Using a BN, we found that self-reported hot flashes at night, and no other factors, were direct predictors of self-reported insomnia in year 1. Surprisingly, we did not identify an association between hormone concentrations and self-reported insomnia. Frequency of insomnia in year 4 was only predicted by frequency of insomnia in year 1, whereas frequency of depression in year 4 was predicted by year 4 insomnia and frequency of depression in year 1. No other factors were direct predictors of insomnia or depression in our model. Conclusions: Therefore, hot flashes at night, previous insomnia, and depression are stronger predictors of how women will self-report frequency of sleep disruptions and treatment may reduce menopausal sleep complaints.

Neuroendocrine pathogenesis of perimenopausal depression

With the development of social economics and the increase of working pressure, more and more women are suffering from long-term serious stress and showing symptoms of perimenopausal depression (PMD). The incidence rate of PMD is increasing, and the physical and mental health are seriously affected. However, due to the lack of accurate knowledge of pathophysiology, its diagnosis and treatment cannot be accurately executed. By consulting the relevant literature in recent years, this paper elaborates the neuroendocrine mechanism of perimenopausal depression from the aspects of epigenetic changes, monoamine neurotransmitter and receptor hypothesis, glial cell-induced neuroinflammation, estrogen receptor, interaction between HPA axis and HPG axis, and micro-organism-brain gut axis. The purpose is to probe into new ways of treatment of PMD by providing new knowledge about the neuroendocrine mechanism and treatment of PMD.

Association between dry eye disease and depression: An umbrella review

Purpose

This umbrella review aimed to summarize the available evidence on the association between dry eye disease and depression.

Methods

We searched the Pubmed, Embase, and Cochrane databases using the search string "(Dry eye syndrome OR Keratoconjunctivitis sicca OR KCS OR Aqueous tear deficiency OR Sjogren syndrome) AND (depression OR depressive symptoms) AND (meta-analysis OR systematic review)" from inception to 20 July 2022. We considered all meta-analyses investigating the association between dry eye disease and depression.

Results

After summarizing the included meta-analyses, it was concluded that dry eye disease is associated with depression. The symptoms of dry eye disease affect the daily lives of patients, thus affecting their mood. However, further evidence is required to confirm this association.

Conclusion

This finding highlights the importance of psychological support for patients with dry eye disease. Future clinical studies should investigate the mechanism underlying the association between dry eye disease and depression.

Isoflavone-Enriched Soybean Leaves (Glycine Max) Alleviate Cognitive Impairment Induced by Ovariectomy and Modulate PI3K/Akt Signaling in the Hippocampus of C57BL6 Mice

(1) Background: The estrogen decline during perimenopause can induce various disorders, including cognitive impairment. Phytoestrogens, such as isoflavones, lignans, and coumestans, have been tried as a popular alternative to avoid the side effects of conventional hormone replacement therapy, but their exact mechanisms and risk are not fully elucidated. In this study, we investigated the effects of isoflavone-enriched soybean leaves (IESLs) on the cognitive impairment induced by ovariectomy in female mice. (2) Methods: Ovariectomy was performed at 9 weeks of age to mimic menopausal women, and the behavior tests for cognition were conducted 15 weeks after the first administration. IESLs were administered for 18 weeks. (3) Results: The present study showed the effects of IESLs on the cognitive function in the OVX (ovariectomized) mice. Ovariectomy markedly increased the body weight and fat accumulation in the liver and perirenal fat, but IESL treatment significantly inhibited them. In the behavioral tests, ovariectomy impaired cognitive functions, but administration of IESLs restored it. In addition, in the OVX mice, administration of IESLs restored decreased estrogen receptor (ER) β and PI3K/Akt expression in the hippocampus. (4) Conclusions: The positive effects of IESLs on cognitive functions may be closely related to the ER-mediated PI3/Akt signaling pathway in the hippocampus.

Association between CYP19A1 rs6493497 and rs936306 polymorphisms and depression susceptibility in the Chinese population

Aim: The CYP19A1 gene encodes the key aromatase for estrogen biosynthesis, and this study aimed to explore the relationship between CYP19A1 rs6493497 and rs936306 polymorphisms and depression risk. Methods: CYP19A1 rs6493497 and rs936306 genotyping was performed on 502 depression patients and 504 healthy controls. Results: In the general population, no significant association was observed between the CYP19A1 rs6493497 variant and depression, whereas that CYP19A1 rs936306 variant significantly reduced depression risk in the recessive model. In subgroup analysis, a significant association of the CYP19A1 rs6493497 variant with reduced depression risk was found in males aged 46-65 in the genotype, dominant and additive models. Conclusion: The CYP19A1 rs936306 variant may reduce depression risk, and the rs6493497 variant is associated with decreased depression risk in males aged 46-65.

Female reproductive factors are associated with the risk of newly diagnosed bipolar disorder in postmenopausal women

Changes in the levels of female sex hormones are associated with mood disorders in middle-aged women. This study investigated the association between female reproductive factors and the development of newly diagnosed bipolar disorder (BD). We used a South Korean nationwide medical records database. Postmenopausal women aged 40 or older who underwent health examinations were identified and followed for the occurrence of BD. We identified female reproductive factors including the age at menarche and menopause, parity, history of breastfeeding, oral contraceptive (OC) use, and hormone therapy (HT), and investigated their association with the occurrence of newly diagnosed BD. During an average of 8.32 years (SD 0.83) of follow-up, the incidence of BD was 0.50 per 1000 person-years in postmenopausal women. Compared to women with menopause at an age of 40 years or younger, those with menopause at an age of 45 years or older showed decreased risks of BD. Compared to women who had never breastfed, those who had breastfed for more than 12 months showed a decreased risk of BD. Compared to women who never received HT, those who received HT showed an increased risk of BD in a time-dependent manner. Among postmenopausal women, later menopause and breastfeeding for more than one year were associated with a decreased risk of BD occurrence, and receiving HT was associated with an increased risk.

Menopause status and climacteric symptoms in a birth cohort of mid-life New Zealand women

BACKGROUND

There is little current research on the transition to natural menopause among contemporary groups of mid-life women at age 40 years.

OBJECTIVE

This study reports on female members of the Christchurch Health and Development Study cohort. This research aimed to: document the menopause status, reproductive outcomes and climacteric symptoms of the women at age 40 years; examine the associations between menopause status and concurrent measures of psychosocial and economic well-being; and document the associations between menopause status and potential predictors of menopause reflecting childhood, family and individual factors prior to age 40 years.

METHODS

The Christchurch Health and Development Study is a longitudinal, representative, prospective cohort of 1265 babies (630 females) born in New Zealand in 1977. At age 40 years, 470 women (who had not experienced surgical menopause) were interviewed on their menopause status, climacteric symptoms and associated factors.

RESULTS

The majority of women were premenopausal, around 20% were perimenopausal and 2% were postmenopausal. Statistically significant associations were found reflecting higher rates of diagnosed reproductive disorder, climacteric symptoms, low occupational status, non-heterosexual sexuality and exposure to childhood sexual abuse amongst both perimenopausal and postmenopausal women at age 40 years.

CONCLUSION

These data will inform directions for future data collection and analyses.

Association between resting-state EEG oscillation and psychometric properties in perimenopausal women

Background

The perimenopausal period is associated with a higher risk of various mood disorders. Similarly, although resting-state electroencephalogram (rsEEG) brain oscillatory activity has been associated with various neuropsychological disorders and behaviours, these issues have not been assessed in perimenopausal women. This study aimed to evaluate quantitative relationships between psychometric properties and rsEEG rhythms (delta, theta, alpha, beta and gamma powers) in perimenopausal women.

Methods

A cross-sectional correlational descriptive study was conducted to quantitatively analyze the correlations between rsEEG low-to-high band activities (delta, theta, alpha, beta, and gamma powers) and psychometric properties in 14 perimenopausal women. Participants completed a psychological inventory comprising the State Anxiety Inventory (SAI), Depression Inventory (DI), Behavioural Inhibition Scale (BIS) and short-form UPPS Impulsive Behaviour Scale (IS) before EEG recording.

Results

Results showed that impulsivity was positively related to the beta power, symmetrical at most channels (frontal, temporal, central, parietal and occipital regions; p < .05); but did not related to the delta, theta, alpha and gamma powers. The brainwave low-to-high bands, delta, theta, alpha, beta and gamma power were not associated with DI, SAI or BIS scores.

Conclusions

This study’s findings propose that significantly enhanced resting-state beta activity is a trait of impulsivity in perimenopausal women. Therefore, results have potential implications for the preclinical or clinical evaluation of these issues in perimenopausal women.

Effects of post-ovariectomy time frame and age on the antidepressant-like actions of estradiol and prolame in female rats

Estrogen replacement therapy (ERT) is an effective treatment for symptoms associated with climacteric and depression some women experience during perimenopause and menopause. The antidepressant-like effects of ERT may depend on the type of estrogen, age, and time when restitution is initiated after hormonal decline. Prolame is a synthetic steroid with estrogenic and antidepressant-like effects that may produce fewer adverse effects. We hypothesize that such actions of prolame on females depend on age and the duration of hormone deprivation period. We assessed the antidepressant-like effects of 17β-estradiol (E₂) and prolame in young and middle-aged rats across different post-ovariectomy (Ovx) time frames. Independent groups of young adults and middle-aged female rats were tested in the forced swimming test (FST) at 3, 8, 16, and 24 weeks post-Ovx. Prolame and E₂ were administered in a sub-chronic schedule consisting of three injections before the FST. Likewise, the utero-trophic effects of these hormones were analyzed. We found that E₂ and prolame reduced immobility in young rats 3 and 8 weeks after Ovx; in contrast, only prolame produced this effect in middle-aged rats three weeks post-Ovx. E₂ and prolame increased the animals' utero-somatic index at all post-Ovx times, but the action of E₂ and prolame produced a greater response in young adult rats. Our findings showed that the antidepressant-like effects of E₂ and prolame depend on the post-Ovx time frame, age, and estrogen type. Interestingly, our results indicate that, in contrast to E₂, prolame maintained its antidepressant effect in middle-aged rats.

Prevalence of post-menopausal depression and associated factors: A web-based cross-sectional study in Greece

OBJECTIVES

The impact of depression on post-menopausal women is an important public health issue but remains largely unknown. The purpose of this study was to identify the prevalence of post-menopausal depression in Greece and outline the profile of the women it affects.

STUDY DESIGN

A sample of post-menopausal women completed an anonymous, self-administered, web-based survey which included the Beck Depression Inventory-ΙΙ (BDI-II) and questions regarding socio-demographic data.

MAIN OUTCOME MEASURES

The dependent variable of interest was a BDI-II score ≥ 20 (the cut-off for moderate depression according to the BDI).

RESULTS

Overall, 502 post-menopausal women participated in the study. The median BDI-II score was 13 (range 0-50); 136 (27.1%) of the women scored ≥ 20 and were considered screen-positive for depression. According to the multivariate logistic regression model, age< 55 years (OR: 1.621; 95% CI: 1.036-2.535), not working (OR: 1.580; 95% CI: 1.013-2.465), smoking (OR: 1.656; 95% CI: 1.081-2.536) and history of depression (OR: 1.650; 95% CI: 1.045-2.604) were independently associated with post-menopausal depression. Subgroup analyses revealed that current smokers (OR: 2.514; 95% CI: 1.485-4.256) had higher odds of moderate depression, while obesity (OR: 2.455; 95% CI: 1.206-4.996), absence of healthcare insurance (OR: 4.413; 95% CI: 1.970-9.887) and a history of depression (OR: 2.253; 95% CI: 1.212-4.190) were identified as independent risk factors for severe post-menopausal depression.

CONCLUSIONS

More than one out of four post-menopausal women were screen-positive for symptoms indicative of depression, while a personal history of depression, age < 55 years, smoking and current working status were independent predictors of its emergence.

Potential mechanisms underlying the therapeutic roles of sinisan formula in depression: Based on network pharmacology and molecular docking study

BACKGROUND

The incidence of depression has been increasing globally, which has brought a serious burden to society. Sinisan Formula (SNSF), a well-known formula of traditional Chinese medicine (TCM), has been found to demonstrate an antidepressant effect. However, the therapeutic mechanism of this formula remains unclear. Thus, the present study aimed to explore the mechanism of SNSF in depression through network pharmacology combined with molecular docking methods.

MATERIALS AND METHODS

Bioactive compounds, potential targets of SNSF, and related genes of depression were obtained from public databases. Essential ingredients, potential targets, and signaling pathways were identified using bioinformatics analysis, including protein-protein interaction (PPI), the Gene Ontology (GO), and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Subsequently, Autodock software was further performed for conducting molecular docking to verify the binding ability of active ingredients to targets.

RESULTS

A total of 91 active compounds were successfully identified in SNSF with the use of the comprehensive network pharmacology approach, and they were found to be closely connected to 112 depression-related targets, among which CREB1, NOS3, CASP3, TP53, ESR1, and SLC6A4 might be the main potential targets for the treatment of depression. GO analysis revealed 801 biological processes, 123 molecular functions, and 67 cellular components. KEGG pathway enrichment analysis indicated that neuroactive ligand-receptor interaction, serotonergic synapse pathways, dopaminergic synapse pathways, and GABAergic synapse pathways might have played a role in treating depression. Molecular docking suggested that beta-sitosterol, nobiletin, and 7-methoxy-2-methyl isoflavone bound well to the main potential targets.

CONCLUSION

This study comprehensively illuminated the active ingredients, potential targets, primary pharmacological effects, and relevant mechanism of the SNSF in the treatment of depression. SNSF might exert its antidepressant effects by regulating the signaling pathway of 5-hydroxytryptamine, dopamine, GABA, and neuroactive ligand receptor interactions. Still, more pharmacological experiments are needed for verification.

Are there differences in symptoms experienced by midlife climacteric women with and without metabolic syndrome? A scoping review

INTRODUCTION

Midlife climacteric women with metabolic syndrome are at high risk for experiencing a complex array of symptoms. The aim of this scoping review was to identify the prevalence, types, and clustering of symptoms in midlife climacteric women with metabolic syndrome and to compare them to symptoms of midlife climacteric women without metabolic syndrome.

METHODS

A three-step search method was used according to Joanna Briggs Institute methodology. Eligibility criteria of participants, concept, context, and types of evidence were selected in alignment with the review questions. Seven databases (PubMed, Embase, Web of Science, CINAHL, PsycINFO, ProQuest Dissertation & Theses, OpenGrey) were searched using search terms with no language or date restrictions. Title and abstract screening, full-text review, data charting, and data synthesis were conducted by two independent researchers based on the eligibility criteria.

RESULTS

The search yielded 3813 studies after removing duplicates with 48 full-text papers assessed for eligibility. A total of eight studies were reviewed and analyzed which reported the prevalence and types of symptoms individually or grouped based on each body system. Midlife climacteric women with metabolic syndrome experience a wide prevalence of individual and grouped urogenital, vasomotor, psychological, sleep, and somatic symptoms. Mental exhaustion had the highest prevalence (84.4%) among the individual symptoms, and urogenital symptoms had the highest prevalence (81.3%) among the grouped symptoms. There were mixed findings on symptoms between midlife climacteric women with metabolic syndrome and without metabolic syndrome. No studies focused on symptom clusters.

CONCLUSION

Our findings will serve as a knowledge basis for understanding symptoms experienced by midlife climacteric women with metabolic syndrome. This new knowledge can assist clinicians in effectively assessing and managing their symptoms in clinical settings and inform future development of targeted symptom management interventions.

Symptom clusters predict risk of metabolic-syndrome and diabetes in midlife: the Study of Women's Health Across the Nation

PURPOSE

Women's cardio-metabolic risk increases in midlife. Previous work relating menopause symptoms to diabetes/Metabolic Syndrome (MetS) does not consider the adverse impact of multiple concurrent physical and psychological symptoms in midlife.

METHODS

Data are from 3097 participants in the Study of Women's Health Across the Nation, a cohort of midlife women followed for over 20 years. Baseline latent symptom classes (LSC) were derived from 58 questions assessing physical, psychological and menopausal symptoms. Six identified LSCs ranged from 1 (most symptoms present at high severity) to 6 (few symptoms present at low severity). Accelerated failure time models estimated time to onset of type 2 diabetes and MetS for each LSC.

RESULTS

Women with multiple high/moderate severity symptoms had an earlier onset of diabetes (13.2%, 14.1% and 20.8% earlier onset in LSCs 1, 2, 3, respectively) and MetS (15.5%, 13.0% and 19.7% earlier onset in LSCs 1, 2, 3, respectively) than women with few/low severity symptoms.

CONCLUSIONS

Having multiple concurrent moderate to high intensity physical and psychological symptoms in midlife are associated with early onset of diabetes and MetS. Monitoring and subsequent intervention on a broad range of symptoms in midlife may significantly mitigate cardio-metabolic risk during this critical life stage.

Using Digital Health Technologies to Manage the Psychosocial Symptoms of Menopause in the Workplace: A Narrative Literature Review

Many women experience vasomotor, psychosocial, physical and sexual symptoms during their menopausal life-stage. Specifically, the psychosocial symptoms of menopause can include loss of confidence, issues with self-identity and body image, inattention and loss of memory, increased levels of stress, and a higher risk of developing anxiety and depression. In the workplace, such symptoms can impact the woman's capacity to perform to her optimal levels. Even so, many women do not seek help to manage their symptoms due to feelings of embarrassment, the possibility of experiencing adverse reactions from others, or the cultural taboos that are attached to the condition.Digital health technologies, including virtual consultations, therapeutic interventions, and participation in online communities of support, provide an important means by which women can obtain information about menopause. In the field of mental health, digital technologies have an increasing evidence base. This paper considers how mental health practitioners can adapt, utilise or recommend digital health strategies to support older women in occupational settings to manage their psychosocial symptoms of menopause.

How do women living with HIV experience menopause? Menopausal symptoms, anxiety and depression according to reproductive age in a multicenter cohort

BACKGROUND

To estimate the prevalence and severity of menopausal symptoms and anxiety/depression and to assess the differences according to menopausal status among women living with HIV aged 45-60 years from the cohort of Spanish HIV/AIDS Research Network (CoRIS).

METHODS

Women were interviewed by phone between September 2017 and December 2018 to determine whether they had experienced menopausal symptoms and anxiety/depression. The Menopause Rating Scale was used to evaluate the prevalence and severity of symptoms related to menopause in three subscales: somatic, psychologic and urogenital; and the 4-item Patient Health Questionnaire was used for anxiety/depression. Logistic regression models were used to estimate odds ratios (ORs) of association between menopausal status, and other potential risk factors, the presence and severity of somatic, psychological and urogenital symptoms and of anxiety/depression.

RESULTS

Of 251 women included, 137 (54.6%) were post-, 70 (27.9%) peri- and 44 (17.5%) pre-menopausal, respectively. Median age of onset menopause was 48 years (IQR 45-50). The proportions of pre-, peri- and post-menopausal women who had experienced any menopausal symptoms were 45.5%, 60.0% and 66.4%, respectively. Both peri- and post-menopause were associated with a higher likelihood of having somatic symptoms (aOR 3.01; 95% CI 1.38-6.55 and 2.63; 1.44-4.81, respectively), while post-menopause increased the likelihood of having psychological (2.16; 1.13-4.14) and urogenital symptoms (2.54; 1.42-4.85). By other hand, post-menopausal women had a statistically significant five-fold increase in the likelihood of presenting severe urogenital symptoms than pre-menopausal women (4.90; 1.74-13.84). No significant differences by menopausal status were found for anxiety/depression. Joint/muscle problems, exhaustion and sleeping disorders were the most commonly reported symptoms among all women. Differences in the prevalences of vaginal dryness (p = 0.002), joint/muscle complaints (p = 0.032), and sweating/flush (p = 0.032) were found among the three groups.

CONCLUSIONS

Women living with HIV experienced a wide variety of menopausal symptoms, some of them initiated before women had any menstrual irregularity. We found a higher likelihood of somatic symptoms in peri- and post-menopausal women, while a higher likelihood of psychological and urogenital symptoms was found in post-menopausal women. Most somatic symptoms were of low or moderate severity, probably due to the good clinical and immunological situation of these women.

Depression, anxiety, and fear of death in postmenopausal women

OBJECTIVE

This study aimed to determine the frequency of depression in postmenopausal women, examine some variables that are thought to be related, and evaluate the relationships between postmenopausal depression, anxiety, and fear of death.

METHODS

The study is a cross-sectional study conducted among postmenopausal women who applied to an Obstetrics and Gynecology Polyclinic in Sakarya, Turkey, between March and September 2018. The study group consisted of 485 postmenopausal women. For statistical analysis, the chi-square test, logistic regression analysis, Mann-Whitney U test, and Spearman correlation analysis were used. Values of P ≤ 0.05 were accepted as statistically significant.

RESULTS

The ages of the participants ranged between 35 and 78 years, and the average was 56.33 ± 7.34 years. Being a widow or separated from one's partner (odds ratio [OR]: 3.478), alcohol consumption (OR: 11.772), any history of illness that required continuous medication (OR: 3.579), presence of any physical disability (OR: 2.242), history of any mental disorder with a physician's diagnosis (OR: 4.213), and number of living children 4 or more (OR: 4.174) were found to be important risk factors for postmenopausal depression. A moderate positive correlation was found between the depression scale and the scores obtained from the anxiety scale (r = 0.467; P = 0.001). No difference was found between participants with and without depression in terms of fear of death.

CONCLUSION

Depression among postmenopausal women is an important health problem that needs to be studied further. No relation was found between depression and fear of death. These results will be beneficial for raising awareness about depression among postmenopausal women and conducting screening for early diagnosis.

Clinical characteristics of bipolar disorders with postpartum depressive onset

BACKGROUND

Postpartum period is associated with an increased risk of bipolar disorder diagnosis and relapse, mainly major depressive episode. Onset during this period might be associated with specific characteristics.

AIM

To compare the socio-demographic and clinical characteristics of parous women presenting with bipolar disorder and an index depressive episode occurring during or outside the postpartum period.

METHODS

Using the multicenter cohort FACE-BD (FondaMental Academic Centers of Expertise for Bipolar Disorders), we considered all women who started their BD with a major depressive episode and have at least one child. We compared two groups depending on the onset: in or outside the postpartum period.

RESULTS

Among the 759 women who started BD with a major depressive episode, 93 (12.2%) had a postpartum onset, and 666 (87.8%) had not. Women who started BD in the postpartum period with a major depressive episode have a more stable family life, more children, an older age at onset, more Bipolar 2 disorder, less history of suicide attempts, less depressive episodes and more mood stabilizer treatments as compared to those who started with a major depressive episode outside the postpartum period. The multivariable logistic regression showed that women with an onset in the postpartum period had significantly more children, less lifetime depressive episodes and a lower rate of history of suicide attempts as compared to women with an onset outside the postpartum period.

DISCUSSION

Our results suggest that women starting their BD with postpartum depression have a more favorable course of BD, especially less history of suicide attempt and less lifetime depressive episodes.

The antidepressant and anxiolytic effect of GPER on translocator protein (TSPO) via protein kinase a (PKA) signaling in menopausal female rats

Postmenopausal depression is mainly caused by the deprivation of ovarian hormones during menopausal transition, it is of great importance to study on the treatment that could effectively relieve symptoms of menopausal depression with fewer side effects. Activation of G-protein-coupled estrogen receptor (GPER) has long been reported to facilitate neuronal plasticity and improve cognition in animals. Meanwhile, it could participate in regulation of intracellular signaling pathways through the characteristic of GPER, ameliorate intracellular mitochondrial function and oxidative stress. However, the impact of GPER on regulating estrogen deprived-depressant and anxious behaviors is still largely unknown. Here we used the ovariectomized female rats to imitate the condition of menopause. Owing to the lateral ventricle administration of G-1 which specifically react with GPER receptor intracerebrally, Ovariectomized (OVX) female rats showed depressive- or anxiety-like phenotypes with attenuated mitochondrial function. In addition, G-1 facilitated PKA activation, which further accelerated TSPO phosphorylation and alleviated menopausal depression- and anxiety-like behaviors. Moreover, PKA inhibitor PKI could partially antagonized the anti-anxiety and anti-depression effects of G-1. Taken together, we concluded that GPER activation might exhibit antidepressant and anxiolytic effect by elevating TSPO phosphorylation via protein kinase A signaling and rescuing the redox status in menopausal female rats.

A meta-analysis on the prevalence of depression in perimenopausal and postmenopausal women in India

INTRODUCTION

The mental health of perimenopausal and postmenopausal women is a relatively understudied area. This review formally explores the prevalence of depression in perimenopausal and postmenopausal women in India.

METHODS

Databases like PubMed, Embase, Cochrane library, Web of Science and Scopus were systematically searched for cross-sectional or cohort studies, providing prevalence of depression in Indian perimenopausal and postmenopausal women. Systematic study selection and data extraction procedures were followed. Quality assessment of individual study was done using AXIS tool. For pooling of effect sizes, the random effects model was used. Funnel plot and Egger's test were used to ascertain publication bias. Subgroup analyses and meta-regression analysis were used to explore heterogeneity in the summary estimates.

RESULTS

After a thorough search, ten studies were found to be eligible and included in this review. Pooled estimate for prevalence of depression (random effects model) in perimenopausal and postmenopausal women in India is 42.47 % (95 % CI: 28.73-57.49, I² = 97.7 %). On visual inspection of the funnel plot and interpreting egger's test (bias: 3.49, SE bias: 3.68, p = 0.37), there was absence of publication bias.

CONCLUSION

We documented 42.47 % pooled prevalence of depression in perimenopausal and postmenopausal women in India.

The association between anti-inflammatory effects of long-term lithium treatment and illness course in Bipolar Disorder

INTRODUCTION

Altered levels of acute-phase proteins are often described in different conditions in BD. Nevertheless, data on the association between lithium treatment and inflammatory markers in the long-term course of BD are still missing. The aim of the study was to examine the long-term course of BD concerning long-term lithium treatment, chronic inflammatory processes and symptom progression. Furthermore, the association between duration of lithium treatment and levels of hsCRP was explored.

METHODS

267 individuals (males= 139, females= 128) with BD were included. Duration of lithium treatment as well as symptom progression, defined as the increase in severity of symptoms, number of episodes a year and duration of episodes within a period of 1.5 years in the past and hsCRP were evaluated.

RESULTS

Male individuals with symptom progression over time had significantly lower duration of lithium treatment compared to individuals without symptoms progression (U= 47.4, p=.037). There were significantly higher levels of hsCRP in male individuals with symptom progression compared to males without symptom progression (U= 47.5, p=.027). Further, there was a significant negative correlation between the duration of lithium treatment and hsCRP levels in the whole sample (r= -.276, p<.05).

CONCLUSION

Our results show that an altered inflammatory state may be associated with a more severe illness course in BD. Further, a longer duration of lithium treatment may be associated with lower symptom progression. The shown association between hsCRP-levels and lithium treatment duration suggests a potential anti-inflammatory effect of lithium as a mediator of its significant positive outcome effect in BD.

Brain functional changes in perimenopausal women: an amplitude of low-frequency fluctuation study

Objective:

To evaluate the effects of sex hormones on amplitude of low-frequency fluctuation (ALFF) in brain regions related to cognition in perimenopausal women.

Methods:

This cross-sectional study involved 25 perimenopausal women and 25 premenopausal women who underwent behavioral evaluations, sex hormone level measurements, and functional magnetic resonance imaging (fMRI). All data and ALFF analyses were preprocessed using the Data Processing Assistant for Resting-State fMRI. Statistical analyses were performed using the Resting-State fMRI Data Analysis Toolkit to explore the differences in ALFF between perimenopausal and premenopausal women. The gray matter volume (GMV) values extracted from brain regions (regions of interest) with significantly different ALFF values between the perimenopausal and premenopausal groups were compared. We analyzed the correlations of the ALFF and GMV values of these regions of interest with the results of behavioral evaluations and sex hormone levels in the two groups.

Results:

Compared with the premenopausal group, the perimenopausal group showed significant ALFF increase in the left gyrus rectus. Regions with decreased ALFF in the perimenopausal group included the left superior temporal gyrus, left inferior frontal gyrus, and left insula. The GMV values of the left gyrus rectus and left superior temporal gyrus were reduced in perimenopausal women. Furthermore, the estradiol level was negatively correlated with the ALFF value of the left gyrus rectus in perimenopausal women.

Conclusions:

The ALFF and GMV values of certain brain regions related to cognitive function were changed in perimenopausal women. Such functional brain alterations may provide more information regarding the mechanism of cognitive dysfunction in perimenopausal women.

Reduced Plasma Estradiol Levels are Associated with Sleep Apnea in Depressed Peri- and Post-Menopausal Women

OBJECTIVE

This study aimed at investigating the correlation between estradiol and sleep apnea among women with major depressive disorders during the perimenopausal and postmenopausal periods.

METHODS

A total of 84 perimenopausal and postmenopausal women diagnosed with depression, and who had been subjected to whole-night polysomnography (PSG) were retrospectively studied. They were assigned into two groups based on the presence of OSA (apnea-hypopnea index (AHI)≥5) (OSA vs non-OSA). The correlation between estradiol levels and apnea-hypopnea index were assessed by logistic regression models after adjusting for age, body mass index (BMI), Hamilton Depression Rating Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), apnea frequency and progesterone.

RESULTS

Among the 84 patients, 45.23% had OSA. Estradiol levels were significantly elevated in non-OSA than in OSA patients (p<0.05). Univariate analysis revealed that elevated estradiol levels are associated with reduced odds of OSA (odds ratio [OR] 0.92, 95% confidence interval [CI] 0.875-0.966, p = 0.001). Multivariate analyses showed that low estradiol levels (OR = 0.859, 95% CI 0.826-0.991, p = 0.031), higher HAMD scores (OR = 1.212, 95% CI 1.012-1.453, p = 0.037), higher apnea frequency (OR = 2.493, 95% CI 1.389-4.473, p = 0.002) and higher BMI (OR=1.635, 95% CI 1.136-2.353, p = 0.008) are correlated with OSA.

CONCLUSION

The ratio of depressed perimenopausal to postmenopausal women comorbid OSA was high. Higher BMI, low estradiol levels, high apnea frequency and high HAMD scores were correlated with OSA diagnosis and could be potential diagnostic markers for OSA in depressed perimenopausal and postmenopausal women. Reduced estradiol levels were correlated with an increased risk of OSA among depressed perimenopausal and postmenopausal women.

Psychosocial factors promoting resilience during the menopausal transition

Despite significant biological, psychological, and social challenges in the perimenopause, most women report an overall positive well-being and appear to be resilient to potentially negative effects of this life phase. The objective of this study was to detect psychosocial variables which contribute to resilience in a sample of perimenopausal women. A total of 135 healthy perimenopausal women aged 40-56 years completed a battery of validated psychosocial questionnaires including variables related to resilience, well-being, and mental health. First, using exploratory factor analysis, we examined which of the assessed variables related to resilience can be assigned to a common factor. Second, linear regression analyses were performed to investigate whether a common resilience factor predicts well-being and mental health in the examined sample of women. Optimism (LOT-R-O), emotional stability (BFI-K-N), emotion regulation (ERQ), self-compassion (SCS-D), and self-esteem (RSES) in perimenopausal women can be allocated to a single resilience-associated factor. Regression analyses revealed that this factor is related to higher life satisfaction (SWLS; β = .39, p < .001, adj. R² = .20), lower perceived stress (PSS-10; β = - .55, p < .001, adj. R² = .30), lower psychological distress (BSI-18; β = - .49, p < .001, adj. R² = .22), better general psychological health (GHQ-12; β = - .49, p < .001, adj. R² = .22), milder menopausal complaints (MRS II; β = - .41, p < .001, adj. R² = .18), and lower depressive symptoms (ADS-L; β = - .32, p < .001, adj. R² = .26). The α levels were adjusted for multiple testing. Our findings confirm that several psychosocial variables (optimism, emotional stability, emotion regulation, self-compassion, and self-esteem) can be allocated to one common resilience-associated factor. This resilience factor is strongly related to women's well-being as well as mental health in perimenopause.

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.

Hormonal Contraceptive Use and Risk of Attempted and Completed Suicide: a Systematic Review and Narrative Synthesis

Despite its widespread use, there is conflicting evidence on the association between hormonal contraception and the risk of suicide among women. This review seeks to identify, appraise and synthesize all studies on the association between hormonal contraceptive use and attempted or completed suicide. A systematic review was performed in accordance with PRISMA guidelines. Relevant citations were identified from three bibliographic databases (MEDLINE, EMBASE, and PsycInfo). Cross-sectional, cohort and case control studies were included. Quality of studies was assessed with validated tools, and a narrative synthesis was conducted to summarize study findings. Nine studies reporting on six samples (n = 683,198) were included. Three studies reported data for the association between hormonal contraceptive use and suicide attempts, and five studies reported data on completed suicides. Both protective and adverse associations between hormonal contraception and risk of suicide were identified. The evidence of the association was weakened by low to moderate methodological quality of studies. Our review found there was substantial variability in the relationships reported between hormonal contraceptive use and suicide risk. Going forward, researchers investigating this topic are encouraged to use population-based samples to take efforts to control for important confounding variables. Additional research is also needed to investigate the effects of more recent hormonal contraceptive methods on suicide risk.

Prior depression affects the experience of the perimenopause - findings from the Swiss Perimenopause Study

BACKGROUND

There is a prevalence peak of depression in the perimenopause, with this reproductive phase being considered a window of vulnerability due to major biopsychosocial changes. Depression has been associated with physical and psychosocial impairment. Prior depression has been shown to be a risk factor for the development of several somatic and mental diseases. We assume that women with prior depression will exhibit increased burdensome symptoms in the perimenopause compared to women without prior depression.

METHODS

A total of 135 perimenopausal women aged 40-56 years participated in the longitudinal Swiss Perimenopause Study. For the purpose of this investigation, a cross-sectional design was chosen. A wide range of validated psychosocial questionnaires were used to compare women with and without prior depression regarding their experience of the perimenopause. Findings were statistically adjusted for multiple testing.

RESULTS

Women with prior depression showed significantly more depressive symptoms (U = 1215.5, p < .01), more menopausal symptoms (U = 1395.0, p < .01), and more sleep disturbances (U = 1583.5, p < .05) than women without prior depression. Moreover, women with a history of depression reported lower subjective mental health (U = 1573.0, p <  05) and felt more isolated (U = 1524.0, p < .05) than those without prior depression.

LIMITATIONS

Self-report data may affect the results. Furthermore, due to the cross-sectional design, causality cannot be inferred.

CONCLUSIONS

Prior depression affects women's experience of the perimenopause. Women with prior depression exhibit significantly more negative health outcomes in the perimenopause than those without prior depression.

The Relationship between Health Status and Social Activity of Perimenopausal and Postmenopausal Women (Health Status and Social Relationships in Menopause)

The quantity and quality of interpersonal relations (including participation in University of the Third Age-U3A) play an important role for women during menopausal changes. Women who have a social network are found to be more positive about menopause, and are less likely to be depressed. This case-control study aimed to analyze the relationship between participating in formal social groups and health status related to physical activity and climacteric and depressive symptoms. The study was conducted among 621 peri- and postmenopausal women aged 50-64 years. The women were classified into two groups: U3A and controls. The participants were selected using a multistage sampling method. The IPAQ (The International Physical Activity Questionnaire), Kupperman Index (KI), and Beck Depression Inventory were used for data collection. Significant differences between the groups were confirmed in the area of professional work (p < 0.001), free time (p < 0.001), and sitting (p < 0.05). The average KI score in the U3A group was higher (t-Student = 2.12, p < 0.05). Depressive symptoms were found in 43.49% of U3A women vs. 51.15% in controls (p < 0.01). We conclude that participation in formal social groups is associated with higher level of physical activity and reduced severity of both climacteric and depressive symptoms.

Long-term supplementation of dehydroepiandrosterone improved depressive-like behaviors by increasing BDNF expression in the hippocampus in ovariectomized rats

Objective

Dehydroepiandrosterone (DHEA), a precursor of estrogen, partially exhibits its biological effect after conversion to estrogen. Its biological significance in perimenopausal depressive disorder or postpartum depression remains unknown. Here, we observed the effects of long-term supplementation of DHEA on depression-like behaviors in ovariectomized rats.

Methods

We established the model as one of sex hormone deficiency in female rats by bilateral ovariectomy. We observed the effects of 13.3 mg/kg DHEA or 0.27 mg/kg estradiol were given daily by gavage for 12 weeks on lipid metabolism, glucose tolerance, and depression-like behaviors in ovariectomized rats. Furthermore, the expression of brain-derived neurotrophic factor (BDNF) and its signaling molecule in the hippocampus was analyzed.

Results

The 12-week supplementation of DHEA or estradiol significantly alleviated weight gain and improved the glucose tolerance in the ovariectomized rats. Moreover, Long-term supplement of DHEA or estradiol significantly increased sucrose preference and locomotion activities, and reduced immobility duration of the ovariectomized rats in the water. Both DHEA and estradiol treatments increased the expression of BDNF, phosphorylation of ERK and CREB, and ERβ, but not that of ERα in the hippocampus of the ovariectomized rats.

Conclusions

Overall, chronic treatment with DHEA improved depression-like behaviors in ovariectomized rats, suggesting that it may be useful for the treatment of sex hormone deficiency such as perimenopausal depressive disorder or postpartum depression.

Linking Mediterranean Diet and Lifestyle with Cardio Metabolic Disease and Depressive Symptoms: A Study on the Elderly in Europe

Against a backdrop of an aging population in Europe, promoting health in older adults becomes a pressing issue. This study aimed to explore if correlations exist between the adherence to the Mediterranean diet and specific health outcomes such as the incidence of chronic cardio metabolic illnesses and experiencing depressive symptoms for elderly individuals. We also looked into probable links between regularly engaging in vigorous physical activities and these health outcomes. Our goal was to clearly demonstrate these relationships while controlling for several individual characteristics and socio-demographic factors on a cross-national scale within Europe. Using the Survey of Health, Aging and Retirement in Europe (SHARE) data for adults aged 50 years and above, we found that following the Mediterranean diet was negatively correlated with the incidence of chronic illnesses, as well as with levels of depressive symptoms. These results were robust to the inclusion of a number of individual and socio-demographic controls. We also showed that regular participation in sports and other strenuous physical activities were associated with lesser chronic disorders and lower levels of depressive symptoms. These findings may have important implications in formulating preventive interventions on ensuring the quality of life of the older population.

The effect of a randomized 12-week soy drink intervention on everyday mood in postmenopausal women

OBJECTIVE

Dietary soy may improve menopausal symptoms, and subsequently mediate mood. This novel study examines various doses of dietary soy drink on everyday mood stability and variability in postmenopausal women.

METHODS

Community-dwelling women (n = 101), within 7 years postmenopause, consumed daily either a low (10 mg, n = 35), medium (35 mg, n = 37), or high (60 mg, n = 29) dose of isoflavones, for 12 weeks. Menopausal symptoms and repeated measures of everyday mood (positive [PA] and negative [NA] affect) (assessed at four time points per day for 4 consecutive days, using The Positive and Negative Affect Schedule) were completed at baseline and follow-up.

RESULTS

The dietary soy intervention had no effect on everyday mood stability (for PA [F{2,70} = 0.95, P = 0.390] and NA [F{2,70} = 0.72, P = 0.489]) or variability (for PA [F{2,70} = 0.21, P = 0.807] and for NA [F{2,70} = 0.15, P = 0.864]), or on menopausal symptoms (for vasomotor [F{2,89} = 2.83, P = 0.064], psychological [F{2,88} = 0.63, P = 0.535], somatic [F{2,89} = 0.32, P = 0.729], and total menopausal symptoms [F{2,86} = 0.79, P = 0.458]). There were between-group differences with the medium dose reporting higher PA (low, mean 24.2, SD 6; and medium, mean 29.7, SD 6) and the low dose reporting higher NA (P = 0. 048) (low, mean 11.6, SD 2; and high, mean 10.6, SD 1) in mood scores. Psychological (baseline M = 18 and follow-up M = 16.5) and vasomotor (baseline M = 4.2 and follow-up M = 3.6) scores declined from baseline to follow-up for the overall sample.

CONCLUSIONS

Soy isoflavones had no effect on mood at any of the doses tested. Future research should focus on the menopause transition from peri to postmenopause as there may be a window of vulnerability, with fluctuating hormones and increased symptoms which may affect mood.
