Review
Hormonal fluctuations in the perimenopause are associated with an array of physical and psychological symptoms. Those with pre-existing mental disorders may experience changes to their symptoms and response to treatment during the perimenopausal and postmenopausal periods and may also be at risk of poorer longer-term physical health outcomes in menopause. The transition towards menopause may be compounded by the oestradiol-suppressing effect of many psychotropics on the hypothalamopituitary-gonadal axis. A collaborative approach between primary care and secondary mental health services is an opportunity for proactive discussion of symptoms and support with management of the perimenopause. This may involve lifestyle measures and/or hormone replacement therapy, which can both lead to improvements in well-being and mental and physical health.

Fluctuations in reproductive hormone levels are associated with mood disruptions in women, such as in postpartum and perimenopausal depression. However, the neural circuit mechanisms remain unclear. Here we report that medial preoptic area (MPOA) GABAergic neurons mediate multifaceted depressive-like behaviors in female mice after ovarian hormone withdrawal (HW), which can be attributed to downregulation of activity in Esr1 (estrogen receptor-1)-expressing GABAergic neurons. Enhancing activity of these neurons ameliorates depressive-like behaviors in HW-treated mice, whereas reducing their activity results in expression of these behaviors. Two separate subpopulations mediate different symptoms: a subpopulation projecting to the ventral tegmental area (VTA) mediates anhedonia and another projecting to the periaqueductal gray mediates immobility. These projections enhance activity of dopaminergic neurons in the VTA and serotonergic neurons in the dorsal raphe, respectively, with increased release of dopamine and serotonin, possibly through disinhibition mechanisms. Thus, the MPOA is a hub that mediates depressive-like behaviors resulting from transitions in reproductive hormone levels.

Review
PURPOSE OF REVIEW
To review recent research regarding cognitive problems during perimenopause, including which menopause-related symptoms, demographic variables, stress exposures, and neural biomarkers are associated with cognitive problems and which interventions demonstrate efficacy at improving cognitive performance.
RECENT FINDINGS
Cognitive problems are common during perimenopause and have a significant impact on a substantial proportion of women. Evidence continues to indicate that verbal learning and verbal memory are the cognitive functions that are most negatively affected during perimenopause, and new research suggests that perimenopause may also be associated with deficits in processing speed, attention, and working memory. Recent research suggests that the cognitive profiles of women transitioning through perimenopause are heterogenous - with some showing strengths and others demonstrating weaknesses in particular cognitive domains. Depression, sleep problems, and vasomotor symptoms in perimenopause may be associated with cognitive difficulties. Recent neuroimaging studies are identifying changes in activity patterns within brain regions that correlate with cognitive performance in perimenopause, but future causal studies are needed to understand the neural mechanisms of cognitive problems during this time. Although clinical treatment studies for cognitive concerns have historically focused on postmenopause, some small trials in perimenopausal samples have been conducted recently but are frequently underpowered. Current guidelines from the North American Menopause Society do not support the use of hormone therapy at any age for cognitive problems. Animal research demonstrates that estradiol and levonorgestrel combined may alleviate working memory problems. Much progress has been made in understanding how perimenopause impacts cognition, and more research is needed to better identify who is at highest risk and how to meaningfully prevent and alleviate cognitive problems during this reproductive stage. Larger-scale randomized intervention trials specifically during perimenopause are urgently needed to address cognitive concerns in this population of women. More consistent reproductive staging, inclusion of covariates, and analyses examining perimenopause specifically would improve study quality and the ability to draw clear conclusions from this research.

Review
AIM
The aim of the study was to explore and understand the organizational culture of a workplace in terms of support and well-being for staff experiencing perimenopausal and menopausal symptoms at work.
DESIGN
It is widely acknowledged that perimenopause and menopause symptoms are experienced by a large percentage of the female workforce. There is a lack of research into how nurses are supported through menopause (Cronin et al. Issues in Mental Health Nursing, 42, 2021, 541-548). The perimenopause and menopause transition can be a challenging time where many may require symptom management and support (RCN, The Menopause and Work: Guidance for RCN Representatives, 2020). This paper presents a case study research (CSR) approach to examine one healthcare organization.
METHODS
CSR design was used: A survey distributed to all staff employed, a review of the available documentation on menopause and interviews with managers from different levels of the organization. The COREQ consolidated criteria was used for reporting the qualitative research reported this study.
RESULTS
The case study generated both quantitative and qualitative data using surveys, interviews and documentation. Data from the organization (n = 6905) showed a majority female workforce of 81.9% with 40.6% aged between 41 and 55 years old, meaning a third of the organization working through perimenopause and menopause. Survey responses (n = 167) collected biographical and psychometric data on the prevalence of perimenopausal and menopausal symptoms. Seven managers were interviewed highlighting two themes: Access to support and culture of menopause and 13 documents from the organization on menopause were analysed for content. The study design permitted an iterative approach to data collection and providing an in-depth understanding of the needs and support for those experiencing perimenopause and menopause. The findings help healthcare organizations to understand their workforce and take in to account the larger numbers of female employees particularly nurses with the need to provide person-centred support mechanisms and an organizational approach for all employees.

Review
With the development and progress of society, people's average life expectancy has increased, and relevant literature reports that the number of postmenopausal women in China continues to increase. With lifespans extended, the transition period and post-menopause period have become the longest essential period in every woman's life. The life quality of women troubled by perimenopausal syndrome has been significantly reduced, which also places a burden on families and society. It is well known that hormone replacement therapy plays a vital role in improving women's menopause-related symptoms and is the most effective medical measure. With research ongoing into the treatment of menopausal symptoms in different patients, dose size, treatment duration, and medication regimens for hormones are still hot topics of discussion. This article reviews the definition, clinical diagnosis, staging, clinical manifestations, and treatment of menopause and explores the current diagnosis and treatment scenarios of perimenopausal syndrome.

INTRODUCTION
Natural menopause is an inevitable biological process with significant implications for women's health. However, the molecular mechanisms underlying menopause are not well understood. This study aimed to investigate the molecular and cellular changes occurring in the ovary before and after perimenopause.
METHODS
Single-cell sequencing data from the GTEx V8 cohort (30-39: 14 individuals; 40-49: 37 individuals; 50-59: 61 individuals) and transcriptome sequencing data from ovarian tissue were analyzed. Seurat was used for single-cell sequencing data analysis, while harmony was employed for data integration. Cell differentiation trajectories were inferred using CytoTrace. CIBERSORTX assessed cell infiltration scores in ovarian tissue. WGCNA evaluated co-expression network characteristics in pre- and post-perimenopausal ovarian tissue. Functional enrichment analysis of co-expression modules was conducted using ClusterprofileR and Metascape. DESeq2 performed differential expression analysis. Master regulator analysis and signaling pathway activity analysis were carried out using MsViper and Progeny, respectively. Machine learning models were constructed using Orange3.
RESULTS
We identified the differentiation trajectory of follicular cells in the ovary as ARID5B+ Granulosa -> JUN+ Granulosa -> KRT18+ Granulosa -> MT-CO2+ Granulosa -> GSTA1+ Granulosa -> HMGB1+ Granulosa. Genes driving Granulosa differentiation, including RBP1, TMSB10, SERPINE2, and TMSB4X, were enriched in ATP-dependent activity regulation pathways. Genes involved in maintaining the Granulosa state, such as DCN, ARID5B, EIF1, and HSP90AB1, were enriched in the response to unfolded protein and chaperone-mediated protein complex assembly pathways. Increased contents of terminally differentiated HMGB1+ Granulosa and GSTA1+ Granulosa were observed in the ovaries of individuals aged 50-69. Signaling pathway activity analysis indicated a gradual decrease in TGFb and MAPK pathway activity with menopause progression, while p53 pathway activity increased. Master regulator analysis revealed significant activation of transcription factors FOXR1, OTX2, MYBL2, HNF1A, and FOXN4 in the 30-39 age group, and GLI1, SMAD1, SMAD7, APP, and EGR1 in the 40-49 age group. Additionally, a diagnostic model based on 16 transcription factors (Logistic Regression L2) achieved reliable performance in determining ovarian status before and after perimenopause.
CONCLUSION
This study provides insights into the molecular and cellular mechanisms underlying natural menopause in the ovary. The findings contribute to our understanding of perimenopausal changes and offer a foundation for health management strategies for women during this transition.
