Review
The levonorgestrel-releasing intrauterine system (LNG-IUS) is a highly effective contraceptive method that has several noncontraceptive benefits. It has been used in various gynecological conditions, such as heavy menstrual bleeding, dysmenorrhea, and endometrial hyperplasia. During the perimenopausal period, hormonal fluctuations occur, and there is a high tendency for the development of several benign gynecologic diseases. Therefore, the use of LNG-IUS in perimenopausal women might be more beneficial than in women belonging to other age groups. Moreover, the insertion of LNG-IUS during the perimenopausal period could confer endometrial protection during estrogen replacement therapy. In this review, we discuss the use of LNG-IUS in perimenopausal women.

This cross-sectional study aimed to explore the knowledge, attitude and practice (KAP) toward sleep disorders and sleep hygiene among perimenopausal women, who were enrolled in Dezhou region of Shandong Province between July and September 2023. A total of 720 valid questionnaires were collected (mean age: 51.28 ± 4.32 years old), and 344 (47.78%) reported experiencing insomnia. The mean scores for knowledge, attitude, practice, and Dysfunctional Beliefs and Attitudes about Sleep (DBAS) were 15.73 ± 7.60 (possible range: 0-36), 29.35 ± 3.15 (possible range: 10-50), 28.54 ± 4.03 (possible range: 10-50), and 6.79 ± 1.90 (possible range: 0-10), respectively. Path analysis showed that knowledge had direct effects on attitude (β = 0.04, 95% CI 0.01-0.07, P = 0.001), and DBAS (β = 0.04, 95% CI 0.02-0.05, P < 0.001). Knowledge had direct effects (β = 0.11, 95% CI 0.08-0.15, P < 0.001) and indirect (β = 0.02, 95% CI 0.00-0.03, P = 0.002) effect on practice. Moreover, attitude also had a direct impact on practice (β = 0.34, 95% CI 0.25-0.43, P < 0.001). In conclusion, perimenopausal women exhibited insufficient knowledge, negative attitude, inactive practice toward sleep disorders and sleep hygiene, and unfavorable DBAS, emphasizing the need for targeted healthcare interventions.

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.

Review
Migraine course is influenced by female reproductive milestones, including menstruation and perimenopause; menstrual migraine (MM) represents a distinct clinical entity. Increased susceptibility to migraine during menstruation and in perimenopause is probably due to fluctuations in estrogen levels. The present review provides suggestions for the treatment of MM and perimenopausal migraine. MM is characterized by long, severe, and poorly treatable headaches, for which the use of long-acting triptans and/or combined treatment with triptans and common analgesics is advisable. Short-term prophylaxis with triptans and/or estrogen treatment is another viable option in women with regular menstrual cycles or treated with combined hormonal contraceptives; conventional prevention may also be considered depending on the attack-related disability and the presence of attacks unrelated to menstruation. In women with perimenopausal migraine, hormonal treatments should aim at avoiding estrogen fluctuations. Future research on migraine treatments will benefit from the ascertainment of the interplay between female sex hormones and the mechanisms of migraine pathogenesis, including the calcitonin gene-related peptide pathway.

Meta-Analysis
IMPORTANCE
Distressing sexual problems are a common complaint of menopausal women. In 2013, a Cochrane review assessed the effect of hormone therapy on sexual function in menopausal women; however, new evidence has since been published, which should be considered.
OBJECTIVE
This systematic review and meta-analysis aims to update the evidence synthesis on the effect of hormone therapy, compared with control, on sexual function in perimenopausal and postmenopausal women.
EVIDENCE REVIEW
Thirteen databases and clinical trial registries (Cochrane Central Register of Controlled Trials, EMBASE, Medical Literature Analysis and Retrieval System Online, PsycINFO, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Literatura Latino-Americana e do Caribe em Ciéncias da Saúde, Database of Abstracts of Reviews of Effects, ClinicalTrials.gov , International Clinical Trials Registry Platform, Iranian Registry of Clinical Trials, Chinese Clinical Trial Registry, ISRCTN) were searched from December 2012 to March 30, 2022. Backward reference searching on all retrieved full texts was also performed. Study quality was assessed using the Cochrane ROB.2 tool. Data were pooled in random-effect model meta-analyses, which included all studies identified in the present search and all studies previously included in the 2013 Cochrane review.
FINDINGS
Forty-seven randomized controlled trials (35,912 participants) were included in the systematic review, and 34 randomized controlled trials (15,079 participants) were included in the meta-analysis. The meta-analysis revealed that, in comparison to control, estrogen therapy (standardized mean difference [SMD], 0.16; 95% confidence interval [CI], 0.02 to 0.29; I2 = 59%; 2,925 participants, 16 studies), estrogen plus progestogen therapy (SMD, 0.11; 95% CI, -0.07 to 0.29; I2 = 65%; 2,432 participants, 7 studies), tibolone (SMD, 0.15; 95% CI, 0.02 to 0.28; I2 = 0%; 916 participants, 2 studies), and selective estrogen receptor modulators (SMD, 0.18; 95% CI, 0.06 to 0.30; I2 = 0%; 1,058 participants, 4 studies) may result in no effect to small benefit on sexual function composite score.
CONCLUSION AND RELEVANCE
Hormone therapy may slightly improve sexual functioning. This potential small benefit should be considered when discussing treatment options for other menopausal symptoms.

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.

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.

The development of natural membranes as coatings for nanoparticles to traverse the blood-brain barrier (BBB) presents an effective approach for treating central nervous system (CNS) disorders. In this study, we have designed a nanogel loaded with PACAP and estrogen (E2), sheathed with exosomes and responsive to reactive oxygen species (ROS), denoted as HA NGs@exosomes. The objective of this novel design is to serve as a potent drug carrier for the targeted treatment of perimenopausal depression. The efficient cellular uptake and BBB penetration of HA NGs@exosomes has been demonstrated in vitro and in vivo. Following intranasal intervention with HA NGs@exosomes, ovariectomized mice under chronic unpredictable mild stress (CUMS) have shown improved behavioral performance, indicating that HA NGs@exosomes produced a rapid-onset antidepressant effect. Moreover, HA NGs@exosomes exhibit notable antioxidant and anti-inflammatory properties and may regulate the expression of pivotal proteins in the PACAP/PAC1 pathway to promote synaptic plasticity. Our results serve as a proof-of-concept for the utility of exosome-sheathed ROS-responsive nanogel as a promising drug carrier for the treatment of perimenopausal depression.

Meta-Analysis
BACKGROUND
The issues related to the treatment of perimenopausal depression (PMD) are the side effects of antidepressants and hormone replacement therapy. The aim of this study was to assess the efficiency and safety of acupuncture and moxibustion in PMD patients.
METHODS
Databases, namely PubMed, Cochrane Library, Web of Science, EMBASE, CNKI, CBM, VIP, and WanFang, were reviewed for related randomized controlled trials dated between database inception and November 22, 2022. The primary outcomes were the efficacy rate and the Hamilton Depression Scale score. The secondary outcomes were the levels of follicle-stimulating hormone, luteinizing hormone, and estradiol and the Kupperman score. Odds ratios (ORs) were generated as the effect size for dichotomous outcomes, while the standard mean difference (SMD) ± standard deviation was used for continuous outcomes. Matrices were developed to demonstrate pairwise comparisons of regimens related to each endpoint. Utilizing Review Manager (RevMan) 5.3, Stata 16.0 and SPSS 21, data were analyzed.
RESULTS
In total, 27 studies involving 2269 PMD patients and 8 therapeutic measures were incorporated into the network meta-analysis (NMA). The NMA showed that warm acupuncture (OR = 1.55, 95% CI: 1.00-2.44), electroacupuncture (OR = 1.34, 95% CI: 1.00-1.8), abdominal acupuncture (OR = 1.19, 95% CI: 0.73-1.96), and common acupuncture (OR = 1.4, 95% CI: 0.9-2.17) were more effective than fluoxetine + menopausal hormone treatment in the treatment of PMD. The NMA also showed that, based on the Hamilton Depression Scale score, warm acupuncture was more effective than the other 4 acupuncture-related treatments, i.e., electroacupuncture (SMD = -1.22, 95% CI: -2.34 to -0.09), thread embedding (SMD = -1.31, 95% CI: -2.21 to -0.40), abdominal acupuncture (SMD = -1.33, 95% CI: -2.42 to -0.24), and common acupuncture (SMD = -1.46, 95% CI: -2.26 to -0.66). The cumulative ranking probability (SUCRA) showed that warm acupuncture (99.6%) was the best treatment method.
CONCLUSIONS
The findings of this network meta-analysis may help patients and therapists choose the best acupuncture therapy for treating perimenopausal depression patients and furnish reliable evidence for guidelines.

Meta-Analysis Review
The comparative effect of exercise interventions on balance in perimenopausal and early postmenopausal women: A systematic review and network meta-analysis of randomised, controlled trials.
In addition to a range of physiological and psychological symptoms, menopause causes a decrement to balance performance and risk of falls. This review aimed to determine the effects of exercise interventions on balance in perimenopausal and early postmenopausal women. Web of Science, PubMed, CINAHL, SPORTDiscus and Cochrane Central Register of Controlled Trials databases were searched. Randomised, controlled trials of exercise interventions in perimenopausal or early postmenopausal populations with an average age of 65 years or younger reporting balance measures were included. Risk of bias was assessed using Cochrane RoB 2. A random effects model network meta-analysis was performed to assess the effect of exercise on balance. Standardised mean differences with 95 % confidence intervals were used as the measure of effect. Twenty-six studies were included after screening. Network meta-analyses were conducted for 5 balance variables. Whole-body vibration (standardised mean difference: 2.25, confidence interval: 0.08; 4.43), balance (standardised mean difference: 1.84, confidence interval: 0.15; 3.53), balance + nutrition (standardised mean difference: 3.81, confidence interval: 1.57; 6.05) and resistance (standardised mean difference: 1.43, confidence interval: 0.41; 2.46) exercise improved Berg balance scale performance. Resistance + aerobic + balance exercise improved one-leg stance (standardised mean difference: 0.80, confidence interval: 0.39; 1.22) and whole-body vibration improved anterior-posterior (standardised mean difference: -0.89, confidence interval: -1.48; -0.31), medio-lateral (standardised mean difference: -0.58, confidence interval: -1.15; -0.01) postural sway and falls indices (standardised mean difference: -0.75, confidence interval: -1.45; -0.04). Exercise improved all balance measures and should be considered as an adjunct therapy in perimenopausal and postmenopausal women. Whole-body vibration was most frequently the highest ranked intervention; resistance and balance training also improved balance.
