    目的:先兆子痫的女性患心血管疾病(CVD)的风险增加。更年期激素治疗(MHT)可能会影响这种风险。我们评估了使用MHT对有和没有先兆子痫的女性心血管风险的影响。
    方法:我们评估了任何CVD的发生,MHT使用者(n=9700)和非使用者(n=19,914)先前先兆子痫的心肌梗死(MI)和中风,在1994-2019年期间没有先兆子痫的MHT用户(n=27,764)和非用户(n=58,248)也是如此。随访从MHT开始(先兆子痫妇女平均年龄50.4岁,非先兆子痫妇女平均年龄50.3岁),平均持续13.3年。
    结果:在先兆子痫妇女中使用MHT与任何CVD的风险显着降低相关(HR0.85,95%CI0.78-0.91),与先前先兆子痫的非使用者相比,MI(HR0.66,95%CI0.55-0.78)和卒中事件(HR0.71,95%CI0.63-0.81)。心血管死亡的风险降低甚至更明显(对于任何CVD死亡,HR0.43,95%CI0.31-0.59;对于MI死亡,HR0.49,95%CI0.30-0.80;对于卒中死亡,HR0.25,95%CI0.10-0.64)。然而,这些风险降低与没有先兆子痫的MHT使用者没有不同。在有先兆子痫的女性中使用MHT的五年内,任何CVD的风险已经降低,但在没有先兆子痫的女性中没有。
    结论:使用MHT可降低先兆子痫妇女的CVD风险。这对于考虑对患有先兆子痫的最近更年期妇女启动MHT的临床医生是重要的。
    OBJECTIVE: Women with prior pre-eclampsia are at increased risk of cardiovascular disease (CVD). Menopausal hormone therapy (MHT) may affect this risk. We evaluated the impact of MHT use on cardiovascular risk between women with and without prior pre-eclampsia.
    METHODS: We assessed the occurrence of any CVD, myocardial infarction (MI) and stroke in MHT users (n = 9700) and non-users (n = 19,914) with prior pre-eclampsia, and likewise in MHT users (n = 27,764) and non-users (n = 58,248) without prior pre-eclampsia over the period 1994-2019. Follow-up started at MHT initiation (mean age 50.4 in pre-eclamptic women and 50.3 in non-pre-eclamptic women) and lasted for a mean of 13.3 years.
    RESULTS: The use of MHT in prior pre-eclamptic women was associated with significant risk reductions for any CVD (HR 0.85, 95 % CI 0.78-0.91), MI (HR 0.66, 95 % CI 0.55-0.78) and stroke events (HR 0.71, 95 % CI 0.63-0.81) in comparison with non-users with prior pre-eclampsia. The risk reductions for cardiovascular deaths were even more pronounced (HR 0.43, 95 % CI 0.31-0.59 for any CVD death; HR 0.49, 95 % CI 0.30-0.80 for MI death; HR 0.25, 95 % CI 0.10-0.64 for stroke death). However, none of these risk reductions differed from those seen in MHT users without prior pre-eclampsia. The risk of any CVD decreased already within five years of MHT use in women with prior pre-eclampsia but not in those without prior pre-eclampsia.
    CONCLUSIONS: The use of MHT is associated with reduced CVD risk in women with prior pre-eclampsia. This is important to clinicians considering the initiation of MHT for recently menopausal women with prior pre-eclampsia.

    目的:评估绝经类型(自发性或手术性)与轻度认知障碍(MCI)之间的关系。
    方法:这项研究是一项横断面研究,观察,以及在九个拉丁美洲国家/地区的妇科咨询中进行的次分析调查。
    方法:我们评估了社会人口统计学,临床,和人体测量数据,痴呆家族史,以及使用蒙特利尔认知评估(MoCA)工具的MCI的存在。
    结果:该研究涉及1185名绝经后妇女,平均年龄为55.3岁,体重指数为26.4kg/m2。他们平均受教育13.3年,37%是家庭主妇。三百九十九人在40岁之前经历了更年期,其中136人患有手术更年期(双侧卵巢切除术)。在经历了40年或更长时间更年期的786名妇女中,110这样做是由于双侧卵巢切除术。在40岁之前或之后经历更年期的女性中,MoCA评分没有差异。然而,手术绝经妇女的MoCA评分低于自发绝经妇女(23.8±4.9vs.25.0±4.3分,分别,p<0.001)。我们的Logistic回归模型与国家内的患者聚集发现MCI和手术绝经之间存在显着关联(OR1.47,95%CI:1.01-2.16),使用(曾经)更年期激素治疗(OR0.33,95%CI:0.21-0.50),且受教育年限>12年(OR0.21,95%CI:0.14-0.30)。
    结论:将40岁以上自然绝经的女性与该年龄之前自然绝经的女性进行比较时,没有观察到发生MCI的风险增加,而那些手术绝经的人,独立于年龄,更容易出现认知能力下降。曾经使用过更年期激素治疗的女性MCI风险较低。需要进一步的研究来深入研究这个主题。
    OBJECTIVE: To evaluate the association between type of menopause (spontaneous or surgical) and mild cognitive impairment (MCI).
    METHODS: This study was a cross-sectional, observational, and sub-analytical investigation conducted within gynecological consultations across nine Latin American countries.
    METHODS: We assessed sociodemographic, clinical, and anthropometric data, family history of dementia, and the presence of MCI using the Montreal Cognitive Assessment (MoCA) tool.
    RESULTS: The study involved 1185 postmenopausal women with a mean age of 55.3 years and a body mass index of 26.4 kg/m2. They had an average of 13.3 years of education, and 37 % were homemakers. Three hundred ninety-nine experienced menopause before 40, including 136 with surgical menopause (bilateral oophorectomy). Out of the 786 women who experienced menopause at 40 or more years, 110 did so due to bilateral oophorectomy. There were no differences in MoCA scores among women who experienced menopause before or after the age of 40. However, lower MoCA scores were observed in women with surgical menopause than in those with spontaneous menopause (23.8 ± 4.9 vs. 25.0 ± 4.3 points, respectively, p < 0.001). Our logistic regression model with clustering of patients within countries found a significant association between MCI and surgical menopause (OR 1.47, 95 % CI: 1.01-2.16), use (ever) of menopausal hormone therapy (OR 0.33, 95 % CI: 0.21-0.50), and having >12 years of education (OR 0.21, 95 % CI: 0.14-0.30).
    CONCLUSIONS: When comparing women who experience spontaneous menopause over the age of 40 with those who undergo it before this age, there was no observed increased risk of developing MCI, while those with surgical menopause, independent of age, are more prone to cognitive decline. Women who have ever used menopausal hormone therapy have a lower MCI risk. Further research is warranted to delve deeper into this topic.

    在卵巢癌诊断之前使用更年期激素治疗(MHT)与改善生存率相关,但这种相关性是否因使用类型和持续时间而异尚无定论;治疗后使用MHT的数据,特别是对健康相关生活质量(HRQOL)的影响,是稀缺的。我们根据诊断前后的MHT使用调查了卵巢癌女性的生存率,在澳大利亚的前瞻性全国队列中,治疗后MHT的使用及其与HRQOL的关联。我们使用Cox比例风险回归来估计风险比(HR)和95%置信区间(CI)以及倾向评分,以减少适应症的混淆。在690名诊断为绝经前后的妇女中,诊断前使用MHT与卵巢癌特异性生存率显着提高26%相关;与高级别浆液性癌(HGSC,HR=0.69,95CI0.54-0.87)。关联在最近或使用时间上没有差异。在诊断为绝经前/围绝经期或年龄≤55岁的HGSC女性中(n=259),治疗后使用MHT与生存率差异无关(HR=1.04,95CI0.48-2.22)。与非用户相比,在治疗后开始MHT的女性在开始MHT前报告的整体HRQOL较差,且在开始MHT后1~3个月仍有这种差异.总之,诊断前使用MHT与提高生存率相关,特别是在HGSC。在≤55岁的女性中,治疗后使用MHT与HGSC的生存率降低无关.需要进一步的大规模研究来了解卵巢癌中更年期特异性HRQOL问题。
    Menopausal hormone therapy (MHT) use before ovarian cancer diagnosis has been associated with improved survival but whether the association varies by type and duration of use is inconclusive; data on MHT use after treatment, particularly the effect on health-related quality of life (HRQOL), are scarce. We investigated survival in women with ovarian cancer according to MHT use before and after diagnosis, and post-treatment MHT use and its association with HRQOL in a prospective nationwide cohort in Australia. We used Cox proportional hazards regression to estimate hazard ratios (HR) and 95% confidence intervals (CI) and propensity scores to reduce confounding by indication. Among 690 women who were peri-/postmenopausal at diagnosis, pre-diagnosis MHT use was associated with a significant 26% improvement in ovarian cancer-specific survival; with a slightly stronger association for high-grade serous carcinoma (HGSC, HR = 0.69, 95%CI 0.54-0.87). The associations did not differ by recency or duration of use. Among women with HGSC who were pre-/perimenopausal or aged ≤55 years at diagnosis (n = 259), MHT use after treatment was not associated with a difference in survival (HR = 1.04, 95%CI 0.48-2.22). Compared to non-users, women who started MHT after treatment reported poorer overall HRQOL before starting MHT and this difference was still seen 1-3 months after starting MHT. In conclusion, pre-diagnosis MHT use was associated with improved survival, particularly in HGSC. Among women ≤55 years, use of MHT following treatment was not associated with poorer survival for HGSC. Further large-scale studies are needed to understand menopause-specific HRQOL issues in ovarian cancer.

    围绝经期不适会由于生理和行为变化而对女性的身体健康产生不利影响。以雌激素和孕激素为基础的激素治疗可以缓解更年期症状,但是补充雌激素可能会对健康产生负面影响。使用天然化合物治疗围绝经期疾病的激素替代疗法的有效性仍不确定。来自体内实验的证据表明,去卵巢大鼠中的阿魏提取物导致更好的性行为。这种效应似乎与阿魏素的植物雌激素特性有关,提取物中的主要生物活性化合物。本研究的目的是评估阿魏提取物的临床影响(以20%阿魏素滴定,并以100mg/die的剂量给予90天),对64名更年期妇女的生活质量。临床试验是随机的,双盲,和安慰剂对照。我们的数据显示,阿魏提取物将与绝经后不适相关的所有症状减少了679%,并显着增强了性行为。此外,补充剂导致接受它的女性的BMI显着改善和氧化应激降低,同时也保持血小板聚集在正常水平。总的来说,这些结果可能表明,补充阿魏提取物可能会恢复或减轻更年期功能障碍。
    Peri-menopausal discomfort can have a detrimental effect on the physical health of women due to physiological and behavioral changes. Estrogen and progesterone-based hormone therapy can alleviate menopausal symptoms, but estrogen supplementation may have negative health effects. The effectiveness of hormone replacement therapy using natural compounds for peri-menopausal disorders is still uncertain. Evidence from in vivo experiments indicates that Ferula L. extract in ovariectomized rats leads to better sexual behavior. The effect seems to be linked to the phytoestrogenic properties of ferutinin, the primary bioactive compound in the extract. The purpose of this study was to assess the clinical impact of Ferula communis L. extract (titrated at 20% ferutinin, and given at doses of 100 mg/die for 90 days) on the quality of life of 64 menopausal women. The clinical trial was randomized, double-blind, and placebo controlled. Our data showed that Ferula communis L. extract reduced by 67 + 9% all symptoms associated to postmenopausal discomfort and enhanced significantly sexual behavior. In addition, the supplement led to a significant improvement of BMI and oxidative stress decrease in the women who received it, while also keeping platelet aggregation within normal levels. Overall, these results could point to the potential use of supplementation with Ferula communis L. extract to revert or mitigate menopause dysfunction.

    背景:女性进入更年期与身体的一些变化有关,包括那些与免疫系统有关的。免疫衰老是免疫细胞功能及其亚群组成的年龄相关变化的结果。更年期激素治疗(MHT)被认为可以部分中和衰老对免疫系统的负面影响。
    目的:我们旨在评估口服和经皮MHT对更年期妇女细胞免疫参数和细胞因子谱的影响。
    方法:包括50名绝经前后和绝经早期妇女。通过流式细胞术和多重分析评估免疫参数。
    结果:我们表明,不同途径的MHT给药导致更年期患者单核细胞表型的显着变化和单核细胞趋化蛋白-1(MCP-1)水平的降低。此外,口服MHT导致NK和B细胞显著增加。经皮MHT观察到T辅助细胞数量的显着增加。此外,口服MHT导致IL-1β水平显著降低。
    结论:我们首次证明口服治疗,与透皮疗法相反,对更年期女性血细胞的特定免疫亚群有更明显的影响。这种作用可能是其在免疫衰老背景下的抗衰老特性以及其在传染病中的保护作用的原因。也许在选择患者管理策略之前,在开具MHT之前测试血液免疫参数或评估免疫状态可能成为临床实践中的常规步骤。
    BACKGROUND: A woman\'s entry into the menopause period is associated with a number of changes in the body, including those related to the immune system. Immune aging is a consequence of age-related changes in the function of immune cells and the composition of their subpopulations. Menopausal hormone therapy (MHT) is thought to partially neutralize the negative effects of aging on the immune system.
    OBJECTIVE: We aimed to evaluate the effect of oral and transdermal MHT on cellular immunity parameters and cytokine profile in menopausal women.
    METHODS: Fifty peri- and early postmenopausal women were included. Immune parameters were assessed by flow cytometry and multiplex analysis.
    RESULTS: We showed that different routes of MHT administration led to significant changes in monocyte phenotype and a decrease in monocyte chemoattractant protein-1 (MCP-1) level in menopausal patients. In addition, oral MHT resulted in a significant increase in NK and B cells. A significant increase in the number of T-helper cells was observed with transdermal MHT. In addition, oral MHT resulted in a significant decrease in IL-1β level.
    CONCLUSIONS: We have demonstrated for the first time that oral therapy, in contrast to transdermal therapy, has a more pronounced effect on specific immune subpopulations of blood cells in menopausal women. This effect is likely to be responsible for its anti-aging properties in the context of immune aging as well as its protective effects in infectious diseases. Perhaps testing blood immune parameters or assessing immune status before prescribing MHT could become a routine step in clinical practice before choosing a patient management strategy.

    纤维肌痛(FM)和更年期疾病具有共同的流行病学和临床特征,FM症状通常在更年期开始。肌肉骨骼疼痛,关节痛,肌痛和其他症状在这两种情况下都很常见。一些研究表明,性激素的停止与FM症状之间存在联系。患有FM的女性在绝经后往往会出现更严重的症状,在接受子宫切除术或不接受卵巢切除术的女性中,FM症状的严重程度可能会恶化。尽管有这些相似之处,必须分别治疗FM和更年期疾病,并遵循既定的管理指南。然而,同样重要的是要认识到两种情况可以在同一患者中共存。至关重要的是,有有限的证据支持更年期激素治疗对初级FM管理的有效性。因此,除非患者还患有更年期综合征,否则不建议对FM进行更年期激素治疗。
    Fibromyalgia (FM) and climacteric conditions share common epidemiological and clinical features, with FM symptoms often beginning during menopause. Musculoskeletal pain, arthralgia, myalgia and other symptoms are frequently seen in both conditions. Some research suggests a link between the cessation of sex hormones and FM symptoms. Women with FM tend to experience more severe symptoms after menopause, and the severity of FM symptoms can worsen in women who have had a hysterectomy with or without oophorectomy. Despite these similarities, it is essential to treat FM and climacteric conditions separately and follow established guidelines for management. However, it is also important to recognize that both conditions can coexist in the same patient. It is crucial to note that there is limited evidence supporting the effectiveness of menopausal hormone therapy for primary FM management. Therefore, menopausal hormone therapy should not be recommended for FM unless the patient also has climacteric syndrome.

    更年期激素治疗(MHT)是治疗更年期相关症状的有效方法。更年期管理指南推荐了个性化的更年期护理方法,包括MHT使用。围绕更年期护理的决策是一个复杂的,迭代过程受到来自女性和医疗保健提供者(HCP)观点的多重因素的影响。这篇叙述性综述旨在总结有关影响更年期相关护理决策的因素的证据。对于HCP,鉴于需要考虑的潜在收益和风险的数量,提供个性化的风险估计在实践中是具有挑战性的,以及可用数据的复杂性,特别是在有时间限制的协商中。寻求更年期护理的妇女有一项艰巨的任务,就是要了解利益与风险状况,以根据受社会文化/经济影响的决策需求做出选择。教育,人口统计学,和个人特征。媒体,社交媒体,和有影响力的名人也影响更年期的看法和围绕它的决策。了解这些因素可以提高共同决策的参与度,对决策和决策过程的满意度,坚持治疗,减少决策遗憾,有效利用资源,以及最终对护理的长期满意度。
    Menopausal hormone therapy (MHT) is an effective treatment for menopause-related symptoms. Menopause management guidelines recommend a personalized approach to menopause care, including MHT use. Decision-making around menopause care is a complex, iterative process influenced by multiple factors framed by perspectives from both women and healthcare providers (HCPs). This narrative review aims to summarize evidence around factors affecting decision-making regarding menopause-related care. For HCPs, the provision of individualized risk estimates is challenging in practice given the number of potential benefits and risks to consider, and the complexity of the data available, especially within time-limited consultations. Women seeking menopause care have the difficult task of making sense of the benefit versus risk profiles to make choices in line with their decisional needs influenced by sociocultural/economic, educational, demographic, and personal characteristics. The press, social media, and influential celebrities also impact the perception of menopause and decision-making around it. Understanding these factors can lead to improved participation in shared decision-making, satisfaction with the decision and decision-making process, adherence to treatment, reduced decisional regret, efficient use of resources, and ultimately long-term satisfaction with care.

    背景:绝经后血清雌激素的减少与从gynoid到android脂肪组织(AT)分布的转变有关。更年期激素治疗(HT)减轻了这种变化和伴随的代谢功能障碍,但其对AT性类固醇代谢的影响尚未被表征。
    目的:我们研究了HT对绝经后妇女皮下和内脏AT雌激素和雄激素浓度及代谢的影响。
    方法:分析了63名口服HT(n=50)和无(n=13)的绝经后妇女的血清,皮下和内脏AT,雌二醇,黄体酮,睾丸激素,雄烯二酮,脱氢表雄酮,使用液相色谱-串联质谱法和血清硫酸雌酮。使用放射性标记的前体测量类固醇硫酸酯酶活性。使用实时逆转录定量聚合酶链反应进行编码性类固醇代谢酶和受体的基因的mRNA表达。
    结果:HT使用者在皮下和内脏AT中的雌酮和雌二醇浓度高4至7倍,与非使用者相比,内脏AT的睾酮降低了30%。与非HT使用者相比,AT使用者的雌激素与雄激素比率高4至12倍。在内脏AT中,雌激素与雄激素比率随HT雌二醇剂量而增加。HT使用者的雌酮和雌二醇的AT与血清比率仍然很高。
    结论:在HT使用者中较高的局部雌激素与雄激素的比率和高的AT与血清雌激素浓度的比率表明HT可能显著影响AT的内分泌性激素代谢,这些局部变化可能与HT对绝经相关腹部肥胖的预防作用有关。
    BACKGROUND: The decrease in serum estrogens after menopause is associated with a shift from a gynoid to an android adipose tissue (AT) distribution. Menopausal hormone therapy (HT) mitigates this change and accompanying metabolic dysfunction, but its effects on AT sex steroid metabolism have not been characterized.
    OBJECTIVE: We studied effects of HT on subcutaneous and visceral AT estrogen and androgen concentrations and metabolism in postmenopausal women.
    METHODS: Serum and subcutaneous and visceral AT from 63 postmenopausal women with (n=50) and without (n=13) per oral HT were analyzed for estrone, estradiol, progesterone, testosterone, androstenedione, dehydroepiandrosterone, and serum estrone sulfate using liquid chromatography-tandem mass spectrometry. Steroid sulfatase activity was measured using radiolabeled precursors. mRNA expression of genes encoding sex steroid-metabolizing enzymes and receptors was performed using real-time reverse transcription quantitative polymerase chain reaction.
    RESULTS: HT users had 4- to 7-fold higher concentrations of estrone and estradiol in subcutaneous and visceral AT, and 30% lower testosterone in visceral AT compared to non-users. Estrogen-to-androgen ratios were 4- to 12-fold higher in AT of users compared to non-users of HT. In visceral AT, estrogen-to-androgen ratios increased with HT estradiol dose. AT to serum ratios of estrone and estradiol remained high in HT users.
    CONCLUSIONS: Higher local estrogen to androgen ratios and high AT to serum ratios of estrogen concentrations in HT users suggest that HT may significantly influence intracrine sex steroid metabolism in AT, and these local changes could be involved in the preventive effect of HT on menopause-associated abdominal adiposity.

    背景:女性特异性生殖因素和外源雌激素的使用与晚年的认知有关。然而,潜在的机制还不清楚。本研究旨在探讨生殖因素对阿尔茨海默病(AD)和脑血管病变神经影像学生物标志物的影响。
    方法:我们评估了参与梅奥诊所衰老研究的389名女性(中位年龄为71.7岁),包括生殖史数据和纵向磁共振成像(MRI)扫描。我们使用线性混合效应模型来检查生殖因素与神经影像学测量变化之间的关联。
    结果:经常使用激素避孕(HC)与整个call体的较高各向异性分数纵向相关,较低的白质高强度(WMH)体积,和更大的皮质厚度在AD元感兴趣区域(ROI)。绝经后>5年开始绝经激素治疗(MHT)与较高的WMH量相关。
    结论:绝经5年后使用HC和启动MHT通常与脑血管病理的神经影像学生物标志物相关。
    结论:使用激素避孕与更好的脑白质(WM)完整性相关。绝经后>5年开始绝经激素治疗与脑WM完整性恶化有关。激素避孕的使用与更大的皮质厚度相关。初潮和绝经年龄以及怀孕次数与影像学检查无关。生殖因素或外源性雌激素与淀粉样蛋白或tauPET之间几乎没有关联。
    Female-specific reproductive factors and exogeneous estrogen use are associated with cognition in later life. However, the underlying mechanisms are not understood. The present study aimed to investigate the effect of reproductive factors on neuroimaging biomarkers of Alzheimer\'s disease (AD) and cerebrovascular pathologies.
    We evaluated 389 females (median age of 71.7 years) enrolled in the Mayo Clinic Study of Aging with reproductive history data and longitudinal magnetic resonance imaging (MRI) scans. We used linear mixed effect models to examine the associations between reproductive factors and changes in neuroimaging measures.
    Ever hormonal contraception (HC) use was longitudinally associated with higher fractional anisotropy across the corpus callosum, lower white matter hyperintensity (WMH) volume, and greater cortical thickness in an AD meta-region of interest (ROI). The initiation of menopausal hormone therapy (MHT) > 5 years post menopause was associated with higher WMH volume.
    HC use and initiation of MHT >5 years post menopause were generally associated with neuroimaging biomarkers of cerebrovascular pathologies.
    Hormonal contraception use was associated with better brain white matter (WM) integrity. Initiation of menopausal hormone therapy >5 years post menopause was associated with worsening brain WM integrity. Hormonal contraception use was associated with greater cortical thickness. Ages at menarche and menopause and number of pregnancies were not associated with imaging measures. There were few associations between reproductive factors or exogenous estrogens and amyloid or tau PET.
