Examining the Health-Related Needs of Females during Menopause: A Systematic Review Study

In silico molecular docking and predictive ADME properties, in vitro antioxidant scavenging capacities, and in vivo pharmacological activities to study the potential of Pterocarpus mildbraedii's Harms (Fabaceae) in preventing vaginal dysbiosis and risk factors for cardiovascular disease in an estropause rat model

Vaginal dysbiosis (VaD) is a common issue among menopausal women, who are particularly susceptible to cardiovascular disease (CVD). Pterocarpus sp. are known to induce estrogen-like activities, which are the key pathways for menopause-related disorders. This study aims to evaluate the potential of Pterocarpus mildbraedii water extract on VaD and CVD risk factors using an estropause (EP) rat model. Furthermore, predictive ADME properties and molecular docking with target proteins were assessed to develop alternative medicinal treatments for menopause. The secondary metabolites in P. mildbraedii water extract (Pm) were analyzed using UHPLC-MS and quantitative phytochemistry methods. The extract's ability to scavenge free radicals was evaluated using DPPH, ABTS, and FRAP tests. Molecular docking assessed the extract's binding ability to various receptors. SwissADME and Molinspiration were utilized to predict its pharmacokinetic and bioactivity properties. Subsequently, the therapeutic potential of Pm was assessed in rats, focusing on its estrogen-like, eubiotic, and cardioprotective activities. UHPLC-MS enables us to identify several compounds. Predictive ADME analyses have indicated that most compounds comply with Lipinski's Rule of Five for oral drugs. Additionally, they inhibit CYP1A2 and bind to several receptors and enzymes through conventional hydrogen bonding. In rats, ovariectomy-induced EP reduced glycogen levels and vaginal lactic acid and decreased in the population of Lactobacillus spp., which is characteristic of VaD. This condition also increases CVD risk factors. Overall, this study underscores the potential of Pterocarpus mildbraedii in preventing VaD and CVD risk factors related to hypoestrogenism. This extract positions itself as a promising alternative treatment for menopause-related disorders.

Ameliorating Effect of Standardized Rice Bran Supplement on Depressive-Like Behaviors in Ovariectomized Mice

Menopausal depression, often associated with hormonal fluctuations such as decreased estrogen levels, imposes significant mental health burdens. Despite the antidepressant biological properties of standardized rice bran supplement (RBS), its impact on menopausal depression and underlying mechanisms remains largely unexplored. In this study, we investigated the antidepressant effects of RBS in a mouse model of estrogen deficiency-induced depression. Ovariectomized (OVX) mice received oral doses of RBS (250 and 1000 mg/kg) and 17β estradiol over a 20-week period. RBS administration resulted in decreased immobility time in the tail suspension and forced swim tests, along with increased locomotor activity in the open field test. Furthermore, RBS enhanced nitric oxide production and neuronal nitric oxide synthase (nNOS) expression in the hippocampi of OVX mice. Additionally, RBS administration phosphorylated extracellular signal-regulated kinase (ERK), cAMP response element-binding protein (CREB), and tropomyosin receptor kinase B and increased the protein expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. These findings suggest that RBS alleviated depressive behaviors in OVX mice by augmenting hippocampal nNOS expression and activating the ERK-CREB-BDNF signaling pathway. Therefore, based on these results, we propose that RBS is a promising agent to treat menopausal depression, a challenging condition.

Sexual activity and respiratory disease: A systematic review

CONTEXT

Sex and gender are related concepts, but they have distinct meanings and implications. Respiratory diseases are a major driver of morbi-mortality. It is frequent that respirologists, primary care doctors, or other specialists, when dealing with respiratory patients, and aiming for a holistic management of their patients, they all skip any question or matter associated with sexual activity or behavior.

OBJECTIVES

To review how sexual activity is explored in respiratory patients.

METHODS

To conduct this review, we endorse PRISMA guidance for reporting systematic reviews, and also the sex and gender equity in research (SAGER) guidelines.

RESULTS

Compared to other conditions such as heart disease, mental disorders, Alzheimer's, or even COVID-19, to date there is no review focused on sexual activity and respiratory health and disease. Asthma, COPD and other respiratory patients can have their sexual activity and behaviors affected by their disease, but also limitations in sex might be the sentinel event of an incident respiratory disease. Asking on sexual desire and related sex issues should not be considered taboo in any respiratory consultation. Importantly, any marketed stereotypes on cigarettes after any sexual activity should be counteracted. Many clinical trials of respiratory drugs keep recruiting few or no women, so research on women's sexual desire and satisfaction lags behind that of men's. By using the available objective tools and validated questionnaires summarized in this review, these important domains of respiratory patients and their partners can be properly identified and managed.

CONCLUSIONS

Sexual activity, depending on age and individual specific conditions, is a fundamental driver of overall health, and therefore of lung health.

Sleep, Mood, and Nutrition Patterns of Postmenopausal Women Diagnosed with Major Depressive Disorder by Menopause Periods

Menopausal women experience changes in ovarian activity and fluctuating hormone levels. The aim of this study was to detect ongoing sleep and nutritional problems in postmenopausal women. This study was conducted with 62 postmenopausal women who had been diagnosed with major depressive disorder, were aged 42-64, were not dieting for at least 1 month, and had been using antidepressants for at least 6 months. The Pittsburgh Sleep Quality Index and Depression Anxiety Stress Scale-42 were used. Anthropometric measurements were taken and body composition analysis was performed. The prevalence of obesity and overweight were 12.9% and 71%, respectively. Hot flashes, night sweats, and mood swing were more common in those who had been through menopause for <5 years. Also, the PSQI, Depression, and Stress scores of those women were higher. Women who had been menopausal for ≥5 years had a higher BMI, waist/hip ratio, and fat mass and better sleep quality and lower daytime dysfunction according to the PSQI. Energy and fat intake were higher, while protein, vitamin C, and calcium intakes were lower in women who had been menopausal for ≥5 years. It is crucial for healthcare professionals to review approaches for early and late menopausal periods and to individualize treatment options, especially in patients whose symptoms persist.

Altered Sexual Response-Related Functional Connectivity and Morphometric Changes Influenced by Sex Hormones across Menopausal Status

Our study retrospectively investigated differential patterns of the functional connectivity (FC) of core brain regions synchronous with morphometric changes associated with sexual dysfunction in menopausal women, and their correlations with sexual hormones. Twenty-three premenopausal women (mean age: 41.52 ± 7.38 years) and 21 menopausal women (mean age: 55.52 ± 2.80 years) underwent sex hormone level measurements with high-resolution T1 and functional magnetic resonance imaging (MRI) during rest, neutral, and sexual arousal conditions. Analysis of covariance adjusted for age was used to compare the FC and gray matter (GM) volume between the two groups. Menopausal women showed lower GM volumes in the superior frontal gyrus (SFG), superior temporal pole, parahippocampal gyrus (PHG), hippocampus (Hip), amygdala (Amg), and cerebellum (Cb) compared to premenopausal women (p < 0.05). In addition, compared to premenopausal women, menopausal women showed decreased FC of seed regions involved in the SFG, frontal eye fields, and Amg, as well as target regions involved in the PHG, Hip, inferior frontal gyrus, Cb, and vermis (p < 0.005). Furthermore, the FC between the right Amg and right Cb and between the left Amg and right Cb during sexual arousal in both groups was positively correlated with total estrogen and estradiol levels, respectively (p < 0.01). The GM volume values in the right Amg and right Cb were positively correlated with total estrogen and estradiol levels (p < 0.05). Our study demonstrated an association between menopause-related differential FC and GM volume variations and fluctuating sex hormones. Our findings highlight that overlapping brain regions with functional alterations and morphometric changes are closely linked with menopausal symptom-related decreases in sexual arousal and hormone levels.
