Ameliorative effects of Kyung-Ok-Ko and its mixture with Pueraria lobata Ohwi on postmenopausal osteoporosis by promoting phytoestrogenic activity in rats. Front Nutr 2023; 10:1171346. [PMID: 37435569 PMCID: PMC10332514 DOI: 10.3389/fnut.2023.1171346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 05/04/2023] [Indexed: 07/13/2023] Open
Abstract
Introduction Kyung-Ok-Ko (KOK) is a popular traditional medicine used as a natural alternative to hormone replacement therapy for treating postmenopausal symptoms in Asia. Pueraria lobata Ohwi (P. lobata) is rich in isoflavones and has been traditionally used in combination with other herbs to produce synergistic and pharmaceutical effects via a multi-target approach for disease treatment. We aimed to investigate the phytoestrogenic effects of KOK extract against postmenopausal symptoms in ovariectomized (OVX) rats and confirm its efficacy by mixing KOK and P. lobata extracts. Methods OVX rats were daily oral administrated with KOK and KOK + P. lobata mixture extracts (300-400 mg/kg) and their body weight and tail temperature were monitored for 12 weeks. The biochemical parameters, estradiol levels, and bone turnover markers were measured in the serum samples. Moreover, the estrogen receptor, ER-α and ER-β expression in the uterus and the uterus morphology were evaluated. AMPK, ATG1/ULK1, and mTOR protein expression in the liver were assessed. Results The 12-week treatment with KOK and KOK + P. lobata mixture extracts did not cause liver damage or hormonal changes in the OVX rats. The treatments reduced the high lipid accumulation-related body weight gain and the tail temperature increase that was induced by ovariectomy. Further, it exhibited protective effects against hyperlipidemia and osteoporosis. No significant difference was observed in uterine weight compared to the OVX-treated group, while endometrial thickness reduction inhibition was observed due to ovariectomy. Bone mineral density (BMD) and serum osteocalcin levels, which decreased in OVX rats, increased with both treatments. Western blotting analysis showed that ER-α and ER-β were not expressed in the treated rats, whereas these proteins were expressed in Sham-operated rats. No significant differences in the phosphorylation of AMPK were observed; however, the ATG1/ULK1 and mTOR protein phosphorylation levels were upregulated and downregulated in the treated rats compared to those of OVX rats, respectively. Conclusion This is the first in vivo study observing the efficacy and synergistic effects of the mixture of KOK and P. lobata. Our results suggest the potential of KOK and KOK + P. lobata mixture as an alternative therapy for alleviating menopausal symptoms.

Abstract
Menopause occurs in all women. During the menopause transition, 80% of women experience vasomotor symptoms that can last an average of 7-10 years or longer, sometimes into the seventh and eighth decades of life. Understanding how to manage vasomotor symptoms (VMS) in older menopausal women is important since these symptoms can negatively impact quality of life. This review provides a practical guide on how to approach VMS treatment either with menopausal hormone therapy or non-hormone options. When initiating, as well as continuing hormone therapy, the factors clinicians should consider as they weigh risks and benefits include assessing a woman's risks related to cardiovascular disease, breast cancer, and osteoporosis. Utilizing a shared decision-making approach in regard to menopausal symptom management should aim to support women and help them maintain health and quality of life.

Abstract
As an organ system, skeletal muscle is essential for the generation of energy that underpins muscle contraction, plays a critical role in controlling energy balance and insulin-dependent glucose homeostasis, as well as vascular well-being, and regenerates following injury. To achieve homeostasis, there is requirement for "cross-talk" between the myogenic and vascular components and their regulatory factors that comprise skeletal muscle. Accordingly, this review will describe the following: [a] the embryonic cell-signaling events important in establishing vascular and myogenic cell-lineage, the cross-talk between endothelial cells (EC) and myogenic precursors underpinning the development of muscle, its vasculature and the satellite-stem-cell (SC) pool, and the EC-SC cross-talk that maintains SC quiescence and localizes ECs to SCs and angio-myogenesis postnatally; [b] the vascular-myocyte cross-talk and the actions of insulin on vasodilation and capillary surface area important for the uptake of glucose/insulin by myofibers and vascular homeostasis, the microvascular-myocyte dysfunction that characterizes the development of insulin resistance, diabetes and hypertension, and the actions of estrogen on muscle vasodilation and growth in adults; [c] the role of estrogen in utero on the development of fetal skeletal-muscle microvascularization and myofiber hypertrophy required for metabolic/vascular homeostasis after birth; [d] the EC-SC interactions that underpin myofiber vascular regeneration post-injury; and [e] the role of the skeletal-muscle vasculature in Duchenne muscular dystrophy.

Abstract
BACKGROUND A later age at natural menopause (ANM) has been linked to several ageing-associated traits including an increased risk of breast and endometrial cancer and a decreased risk of lung cancer, osteoporosis and Alzheimer disease. However, ANM is also related to several proxies for overall health that may confound these associations. METHODS We investigated the causal association of ANM with these clinical outcomes using Mendelian randomization (MR). Participants and outcomes analysed were restricted to post-menopausal females. We conducted a one-sample MR analysis in both the Women's Health Initiative and UK Biobank. We further analysed and integrated several additional data sets of post-menopausal women using a two-sample MR design. We used ≤55 genetic variants previously discovered to be associated with ANM as our instrumental variable. RESULTS A 5-year increase in ANM was causally associated with a decreased risk of osteoporosis [odds ratio (OR) = 0.80, 95% CI (0.70-0.92)] and fractures (OR = 0.76, 95% CI, 0.62-0.94) as well as an increased risk of lung cancer (OR = 1.35, 95% CI, 1.06-1.71). Other associations including atherosclerosis-related outcomes were null. CONCLUSIONS Our study confirms that the decline in bone density with menopause causally translates into fractures and osteoporosis. Additionally, this is the first causal epidemiological analysis to our knowledge to find an increased risk of lung cancer with increasing ANM. This finding is consistent with molecular and epidemiological studies suggesting oestrogen-dependent growth of lung tumours.

Abstract
Background Women in the peri- or postmenopause can experience symptoms related to the gradual degradation of ovarian function. Hormone replacement therapy (HRT) is the most effective therapy to treat common menopausal symptoms such as hot flashes and vaginal discomfort. However, safety concerns have been raised revolving, among others also, around the risk of breast cancer. Methods This article is based on a selective literature search for relevant studies regarding HRT use and the risk of breast cancer in the general population or BRCA carriers, the risk of breast cancer recurrence, or the risk of breast cancer in situ. Summary HRT can lead to little or no increase in breast cancer risk. The risk depends on the duration and composition of the HRT and decreases after stopping the treatment. Data assessing the oncological safety of HRT after breast cancer are inconsistent. According to current knowledge, HRT is fundamentally contraindicated after breast cancer but can be individually considered after a risk-benefit assessment and when nonhormonal therapies have failed. The same applies to HRT after DCIS, which should not be routinely offered but nonetheless can be considered in individual cases. HRT can be offered up to the age of natural menopause for BRCA mutation carriers who are undergoing risk-reducing bilateral salpingo-oophorectomy and do not have a personal history of breast cancer, but is contraindicated in BRCA mutation carriers who have already had breast cancer.

Abstract
Sex recorded at birth, gender identity, and feminizing gender-affirming hormone therapy (fGAHT) likely contribute to cardiovascular disease (CVD) risk in transgender women. Understanding the interplay of these factors is necessary for the provision of safe, affirming, and lifesaving care. Among transgender women taking fGAHT, data show increases in CVD mortality and rates of myocardial infarction, stroke, and venous thromboembolism compared to reference populations, depending on study design and comparators. However, most studies are observational with a paucity of contextualizing information (e.g., dosing, route of administration, gonadectomy status), which makes it difficult to parse adverse fGAHT effects from confounders and interaction with known CVD risk factors (e.g., obesity, smoking, psychosocial and gender minority stressors). Increased CVD risk in transgender women points toward a need for greater attention to CVD management in this population including cardiology referral when indicated and additional research on the mechanisms and mediators of CVD risk.

Abstract
Epidemiological studies imply there is a higher risk of cardiovascular disease in menopausal women. Some explanations suggest a lack of estrogens as the cause, but estrogens do not disappear completely and are just transformed into different products called estrogenic degradation metabolites (EDMs). When estrogens are metabolized, reactive oxygen species (ROS) increase, causing DNA damage and increasing oxidative stress. These conditions are associated to neurodegenerative diseases and different types of cancer. However, their effect on the cardiovascular system remains unknown. This paper compares estrogenic metabolite levels in serum from post-menopausal women with cardiovascular risk (CAC>1) and with establish cardiovascular disease (CVD), against levels in healthy women (Ctrl). Sample sera were obtained from the Genetics of Atherosclerotic Disease (GEA) Mexican Study. Serum levels of eleven estrogenic metabolites were quantified by High performance liquid chromatography (HPLC) and oxidative stress markers such as ROS, lipoperoxidation levels (TBARS), total antioxidant capacity (TAC), super oxide dismutase activity (SOD) and cytokine levels were evaluated. 8-hydroxy-2-deoxyguanosine (8-OHdG) was also determined as a marker of nuclear damage.There were significant differences between serum levels of some EDMs in CAC> 1 and CVD vs. serum levels in Ctrl women. Results also revealed an increase in oxidative stress and a diminished capacity to manage oxidative stress. These findings provide an overview, and suggest that some estrogenic metabolites may be associated with an increased risk of CVD in menopausal women. However, additional studies are needed to evaluate the impact of these EDMs directly on cardiovascular function.

Abstract
OBJECTIVE Appraisal of cancer survival is essential for cancer control, but studies related to gynecological cancer are scarce. Using cancer registration data, we conducted an in-depth survival analysis of cervical, uterine corpus, and ovarian cancers in an urban district of Shanghai during 2002-2013. MATERIALS AND METHODS The follow-up data of gynecological cancer from the Changning District of Shanghai, China, were used to estimate the 1-5-year observed survival rate (OSR) and relative survival rate (RSR) by time periods and age groups during 2002-2013. Age-standardized relative survival rates estimated by the international cancer survival standards were calculated during 2002-2013 to describe the prognosis of cervical, uterine corpus, and ovarian cancers among women in the district. RESULTS In total, 1307 gynecological cancer cases were included in the survival analysis in the district during 2002-2013. Among gynecological cancers, the 5-year OSRs and RSRs of uterine corpus cancer were highest (5-year OSR 84.40%, 5-year RSR 87.67%), followed by those of cervical cancer (5-year OSR 73.58%, 5-year RSR 75.91%), and those of ovarian cancer (5-year OSR 53.89%, 5-year RSR 55.90%). After age adjustment, the 5-year relative survival rates of three gynecological cancers were 71.23%, 80.11%, and 43.27%, respectively. CONCLUSION The 5-year relative survival rate did not show a systematic temporal trend in cervical cancer, uterine cancer, or ovarian cancer. The prognosis in elderly patients was not optimistic, and this needs a more advanced strategy for early diagnosis and treatment. The age structure of gynecological cancer patients in the district tended to be younger than the standardized age, which implies that more attention to the guidance and health education for the younger generation is needed.

Abstract
Breast cancer is one of the most common and well-known types of cancer among women worldwide and is the most frequent neoplasm in intact female dogs. Female dogs are considered attractive models or studying spontaneous breast cancer, whereas female rats are currently the most widely used animal models for breast cancer research in the laboratory context. Both female dogs and female rats have contributed to the advancement of scientific knowledge in this field, and, in a "One Health" approach, they have allowed broad understanding of specific biopathological pathways, influence of environmental factors and screening/discovery of candidate therapies. This review aims to clearly showcase the similarities and differences among woman, female dog and female rat concerning to anatomical, physiological and histological features of the mammary gland and breast/mammary cancer epidemiology, in order to better portray breast tumorigenesis, and to ensure appropriate conclusions and extrapolation of results among species. We also discuss the major aspects that stand out in these species. The mammary glands of female dogs and women share structural similarities, especially with respect to the lactiferous ducts and lymphatic drainage. In contrast, female rats have only one lactiferous duct per nipple. A comprehensive comparison between humans and dogs is given a special focus, as these species share several aspects in terms of breast/mammary cancer epidemiology, such as age of onset, hormonal etiology, risk factors, and the clinical course of the disease. Holistically, it is clear that each species has advantages and limitations that researchers must consider during the development of experimental designs and data analysis.

Abstract
Understanding the role of both menopausal hormone therapy (MHT) along with non-hormonal options for the treatment of vasomotor symptoms, sleep disruption, and genitourinary symptoms after menopause is critical to the health of women during middle and later life. Recent updates to the evidence for the treatment of menopausal symptoms pertaining to both hormonal and non-hormonal therapies as well as updated guidance from specialty societies can help guide clinicians in their treatment of women going through natural menopause or with estrogen deficiencies due to primary ovarian insufficiency or induced menopause from surgery or medications. The objective of this narrative review is to provide clinicians with an overview of MHT for the use of menopausal symptoms in women, incorporating updated primary evidence for risk versus benefit profiles, recent specialty society recommendations, and alternative, non-hormonal options. In this review, we summarize literature on the use of MHT for menopause-related symptomatology including options for formulations and dosages of MHT, non-hormonal treatment options, and the risk-benefit profile of MHT including long-term health consequences (eg, cardiovascular disease, cognitive decline, venous thromboembolism, and fracture risk). Finally, we highlight areas in which future research is needed to advance care of women after menopause. In summary, both hormonal (MHT) and non-hormonal options exist to treat symptoms of menopause. There is strong evidence for safety and effectiveness of MHT for the treatment of vasomotor symptoms among women who are less than 60 years of age, less than 10 years since menopause, and without significant cardiometabolic comorbidities. For others, treatment with hormonal versus non-hormonal therapies can be considered based on individual risk profiles, as well as other factors such as drug formulation, therapeutic goals, and symptom severity.

Abstract
Menopausal hormone treatment (MHT) is recommended for the management of menopause symptoms. The Women's Health Initiative (WHI) placebo-controlled randomised study examined the effects of continuous combined or estrogen-only MHT on the risk of non-communicable diseases (NCDs) in post-menopausal women. The study was terminated prematurely after an interim analysis showed an increased risk of breast cancer diagnosis, which led to a rapid decrease in MHT use worldwide. Subsequently, limitations of the study design and its interpretation in the context of other clinical studies has contributed to a more nuanced appreciation of the risk-benefit profile of differing MHT regimens regarding risk associated with the class of progestogen prescribed, its pattern of prescription, duration of use and timing of initiation related to menopause onset. This review provides a contextual interpretation of the WHI placebo-controlled study and evaluates the impact of bioidentical MHT, with a focus on combined therapies containing micronised progesterone, on the risk of chronic NCDs in post-menopausal women.

Abstract
BACKGROUND Menopausal estrogen depletion increases the risk of cardiovascular disease and of osteoporosis. Both of these risks can be increased by thyroid dysfunction as well. This cumulation of risks will be presented. METHODS This review is based on publications retrieved by a selective search in PubMed (publications dated January 2000 to October 2022) for clinical trials, meta-analyses, randomized controlled trials, and systematic reviews containing the keywords "menopause and thyroid disorders." RESULTS Hyperthyroidism and menopause have similar symptoms. Decreased levels of thyroid-stimulating hormone (TSH) are found in 8-10% of women in their fifth and sixth decades. TSH is decreased in 21.6-27.2% of women treated with L-thyroxine; decreased TSH is associated with increased cardiovascular mortality (hazard ratio [HR] 3.3, 95% confidence interval [CI]: [1.3; 8.0]) and increased mortality of all causes (HR 2.1; 95% CI: [1.2; 3.8]). Menopausal estrogen depletion accelerates the risk of cardiovascular disease and causes a disproportionate loss of bone density. In hyperthyroidism, bone density is decreased, and the risk of vertebral fractures is increased (HR 3.57; 95% CI: [1.88; 6.78]). CONCLUSION The risk of heart diseases and bone diseases accelerates around the time of the menopause. Early detection and treatment of hyperthyroidism, which can further elevate the risk of both of these diseases is therefore required. In perimeno - pausal and postmenopausal women who are being treated for hypothyroidism, TSH suppression must be avoided. Thyroid dysfunction is common in women; its manifestations are less obvious with advancing age, making clinical diagnosis more difficult, yet it can have major deleterious effects. Thus, the indications for measuring TSH in perimenopausal women should be kept broad, rather than restrictive.

Abstract
OBJECTIVE This study aimed to evaluate the risk of ovarian cancer associated with hormone therapy regimens using a Korean population-based study. METHODS This retrospective cohort study used national health checkup and insurance data from January 1, 2002, to December 31, 2019, provided by Korea's National Health Insurance Service. Women older than 40 years who recorded "menopause" in the questionnaire from 2002 to 2011 were included in this study. Menopausal hormone therapy (MHT) preparations were classified into tibolone, combined estrogen plus progestin by the manufacturer, combined estrogen plus progestin by physician, estrogen, and topical estrogen groups. The number of participants recorded as menopausal during the national health examination between 2002 and 2011 was 2,506,271. The MHT and non-MHT groups consisted of 373,271 and 1,382,653 patients, respectively. The hazard ratios (HR) of ovarian cancer according to MHT type, age at inclusion, body mass index, region, socioeconomic status, Charlson comorbidity index, age at menarche, age at menopause, parity, smoking, alcohol consumption, physical exercise, and period from menopause to inclusion were evaluated. RESULTS The risk of ovarian cancer was reduced in the tibolone group (HR, 0.84; 95% confidence interval, 0.75-0.93; P = 0.003) and in patients in rural areas (HR, 0.90; 95% confidence interval, 0.845-0.98; P = 0.013). The risk of ovarian cancer was not related to the other MHT treatments. CONCLUSION Tibolone was associated with a lower risk of ovarian cancer. No other MHT was associated with ovarian cancer.

Abstract
Importance Postmenopausal females represent around 70% of all individuals with Alzheimer disease. Previous literature shows elevated levels of tau in cognitively unimpaired postmenopausal females compared with age-matched males, particularly in the setting of high β-amyloid (Aβ). The biological mechanisms associated with higher tau deposition in female individuals remain elusive. Objective To examine the extent to which sex, age at menopause, and hormone therapy (HT) use are associated with regional tau at a given level of Aβ, both measured with positron emission tomography (PET). Design, Setting, and Participants This cross-sectional study included participants enrolled in the Wisconsin Registry for Alzheimer Prevention. Cognitively unimpaired males and females with at least 1 18F-MK-6240 and 11C-Pittsburgh compound B PET scan were analyzed. Data were collected between November 2006 and May 2021. Exposures Premature menopause (menopause at younger than 40 years), early menopause (menopause at age 40-45 years), and regular menopause (menopause at older than 45 years) and HT user (current/past use) and HT nonuser (no current/past use). Exposures were self-reported. Main Outcomes and Measures Seven tau PET regions that show sex differences across temporal, parietal, and occipital lobes. Primary analyses examined the interaction of sex, age at menopause or HT, and Aβ PET on regional tau PET in a series of linear regressions. Secondary analyses investigated the influence of HT timing in association with age at menopause on regional tau PET. Results Of 292 cognitively unimpaired individuals, there were 193 females (66.1%) and 99 males (33.9%). The mean (range) age at tau scan was 67 (49-80) years, 52 (19%) had abnormal Aβ, and 106 (36.3%) were APOEε4 carriers. There were 98 female HT users (52.2%) (past/current). Female sex (standardized β = -0.41; 95% CI, -0.97 to -0.32; P < .001), earlier age at menopause (standardized β = -0.38; 95% CI, -0.14 to -0.09; P < .001), and HT use (standardized β = 0.31; 95% CI, 0.40-1.20; P = .008) were associated with higher regional tau PET in individuals with elevated Aβ compared with male sex, later age at menopause, and HT nonuse. Affected regions included medial and lateral regions of the temporal and occipital lobes. Late initiation of HT (>5 years following age at menopause) was associated with higher tau PET compared with early initiation (β = 0.49; 95% CI, 0.27-0.43; P = .001). Conclusions and Relevance In this study, females exhibited higher tau compared with age-matched males, particularly in the setting of elevated Aβ. In females, earlier age at menopause and late initiation of HT were associated with increased tau vulnerability especially when neocortical Aβ elevated. These observational findings suggest that subgroups of female individuals may be at higher risk of pathological burden.

Abstract
OBJECTIVE Menopausal hormone therapy (MHT) is known to reduce the incidence of type 2 diabetes mellitus (T2DM); however, since the Women's Health Initiative study, the types and doses of female hormones used for MHT have changed considerably. Therefore, this study was conducted to determine whether MHT, which is currently widely prescribed, increases the risk of T2DM. METHOD We performed a retrospective cohort study based on national health insurance data and cancer screening data from 2002 to 2019. We included the MHT group as postmenopausal women older than 40 years who used at least one MHT for at least 6 months between 2003 and 2011. We subclassified the MHT group into five categories; tibolone, combined estrogen plus progestin by the manufacturer (CEPM), oral estrogen, combined estrogen plus progestin by the physician (CEPP), and transdermal estrogen. We selected the non-MHT group as postmenopausal women who had never been prescribed MHT from 2002 to 2019. We compared the incidence of T2DM between the MHT group and the non-MHT group. RESULTS We enrolled 330,771 women in the MHT group and 798,550 women in the control group. T2DM was diagnosed in 15.2% of the non-MHT group, 16.6% of the tibolone group, 12.1% of the CEPM group, 16.6% of the oral estrogen group, 15.4% of the CEPP group, and 17% of the transdermal estrogen group. In Cox proportional hazard analysis adjusted for variable factors, tibolone, oral estrogen, CEPP, and transdermal estrogen increased the incidence of T2DM. In contrast, there was no change in the risk of T2DM in the CEPM group. CONCLUSIONS MHT, including tibolone, which is currently the most prescribed agent, increased the risk of T2DM; however, CEPM did not increase the risk of T2DM. Only tibolone increased the risk of T2DM in participants older than 70 years.

Abstract
OBJECTIVE To evaluate the impact of menopause symptoms on work outcomes and to assess the estimated economic impact. PATIENTS AND METHODS Women aged 45 to 60 years receiving primary care at 1 of the 4 Mayo Clinic sites were invited to participate in a survey study (Hormones and ExpeRiences of Aging) from March 1 through June 30, 2021. A total of 32,469 surveys were sent, with 5219 responses (16.1% response rate). Of the 5219 respondents, 4440 (85.1%) reported current employment information and were included in the study. The primary outcome was self-reported adverse work outcomes related to menopause symptoms assessed by the Menopause Rating Scale (MRS). RESULTS The mean age of the 4440 participants was 53.9±4.5 years, with the majority being White (4127 [93.0%]), married (3398 [76.5%]), and educated (2632 [59.3%] college graduate or higher); the mean total MRS score was 12.1, signifying moderate menopause symptom burden. Overall, 597 women (13.4%) reported at least one adverse work outcome due to menopause symptoms; 480 women (10.8%) reported missing work in the preceding 12 months (median, 3 days missed). The odds of reporting an adverse work outcome increased with increasing menopause symptom severity; women in the highest quartile of total MRS scores were 15.6 (95% CI, 10.7 to 22.7; P<.001) times more likely to have an adverse work outcome vs those in the first quartile. Based on workdays missed due to menopause symptoms, we estimate an annual loss of $1.8 billion in the United States. CONCLUSION This large cross-sectional study identified a major negative impact of menopause symptoms on work outcomes and the need to improve medical treatment for these women and make the workplace environment more supportive. Additional studies are needed to confirm these findings in larger and more diverse groups of women.

Targeting inhibition of prognosis-related lipid metabolism genes including CYP19A1 enhances immunotherapeutic response in colon cancer. J Exp Clin Cancer Res 2023; 42:85.

Abstract
BACKGROUND Lipid metabolic reprogramming in colon cancer shows a potential impact on tumor immune microenvironment and is associated with response to immunotherapy. Therefore, this study aimed to develop a lipid metabolism-related prognostic risk score (LMrisk) to provide new biomarkers and combination therapy strategies for colon cancer immunotherapy. METHODS Differentially expressed lipid metabolism-related genes (LMGs) including cytochrome P450 (CYP) 19A1 were screened to construct LMrisk in TCGA colon cancer cohort. The LMrisk was then validated in three GEO datasets. The differences of immune cell infiltration and immunotherapy response between LMrisk subgroups were investigated via bioinformatic analysis. These results were comfirmed by in vitro coculture of colon cancer cells with peripheral blood mononuclear cells, human colon cancer tissue microarray analysis, multiplex immunofluorescence staining and mouse xenograft models of colon cancer. RESULTS Six LMGs including CYP19A1, ALOXE3, FABP4, LRP2, SLCO1A2 and PPARGC1A were selected to establish the LMrisk. The LMrisk was positively correlated with the abundance of macrophages, carcinoma-associated fibroblasts (CAFs), endothelial cells and the levels of biomarkers for immunotherapeutic response including programmed cell death ligand 1 (PD-L1) expression, tumor mutation burden and microsatellite instability, but negatively correlated with CD8+ T cell infiltration levels. CYP19A1 protein expression was an independent prognostic factor, and positively correlated with PD-L1 expression in human colon cancer tissues. Multiplex immunofluorescence analyses revealed that CYP19A1 protein expression was negatively correlated with CD8+ T cell infiltration, but positively correlated with the levels of tumor-associated macrophages, CAFs and endothelial cells. Importantly, CYP19A1 inhibition downregulated PD-L1, IL-6 and TGF-β levels through GPR30-AKT signaling, thereby enhancing CD8+ T cell-mediated antitumor immune response in vitro co-culture studies. CYP19A1 inhibition by letrozole or siRNA strengthened the anti-tumor immune response of CD8+ T cells, induced normalization of tumor blood vessels, and enhanced the efficacy of anti-PD-1 therapy in orthotopic and subcutaneous mouse colon cancer models. CONCLUSION A risk model based on lipid metabolism-related genes may predict prognosis and immunotherapeutic response in colon cancer. CYP19A1-catalyzed estrogen biosynthesis promotes vascular abnormality and inhibits CD8+ T cell function through the upregulation of PD-L1, IL-6 and TGF-β via GPR30-AKT signaling. CYP19A1 inhibition combined with PD-1 blockade represents a promising therapeutic strategy for colon cancer immunotherapy.

Oral estradiol/micronized progesterone may be associated with lower risk of venous thromboembolism compared with conjugated equine estrogens/medroxyprogesterone acetate in real-world practice. Maturitas 2023; 172:23-31. [PMID: 37084589 DOI: 10.1016/j.maturitas.2023.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 04/03/2023] [Accepted: 04/07/2023] [Indexed: 04/23/2023]
Abstract
OBJECTIVES The Women's Health Initiative study reported an increased risk of venous thromboembolism among menopausal women treated with conjugated equine estrogens/medroxyprogesterone acetate (CEE/MPA) versus placebo. Newer hormone therapies may have a lower venous thromboembolism risk. The study compared the risk of venous thromboembolism between women treated with the combined oral product 17β-estradiol/micronized progesterone (E2/P4) and those treated with oral CEE/MPA regimens. STUDY DESIGN In a retrospective longitudinal study using real-world claims data from April 2019 to June 2021, women aged 40 years or more treated with oral E2/P4 or oral CEE/MPA who did not have a venous thromboembolism diagnosis before first dispensing claim of CEE/MPA or E2/P4 identified on or after May 1st 2019 (index date) were observed for 6 months or more after the index date. Oral E2/P4 and oral CEE/MPA had been prescribed by the treating physician in real-world practice and were observed through pharmacy dispensing records. MAIN OUTCOME MEASURES Venous thromboembolism risk was compared between women receiving oral E2/P4 versus oral CEE/MPA. RESULTS The study included 36,061 women treated with oral E2/P4 or oral CEE/MPA. In the analyses weighted by the inverse probability of treatment for control of potential confounding factors, the incidence of venous thromboembolism was significantly lower for oral E2/P4 compared with oral CEE/MPA (37/10,000 women-years for oral E2/P4 vs 53/10,000 women-years for oral CEE/MPA; incidence rate ratio 0.70, 95 % confidence interval: 0.53-0.92). CONCLUSIONS Real-world evidence suggests that the risk of venous thromboembolism is significantly lower among women treated with oral E2/P4 compared with oral CEE/MPA.

Abstract
BACKGROUND Many nutritional supplements and pharmacological agents have been reported to show preventive effects on colorectal adenoma and colorectal cancer (CRC). We performed a network meta-analysis to summarize such evidence and assess the efficacy and safety of these agents. METHODS We searched PubMed, Embase, and the Cochrane Library for studies published in English until October 31, 2021 that fit our inclusion criteria. We performed a systematic review and network meta-analysis to assess the comparative efficacy and safety of candidate agents (low-dose aspirin [Asp], high-dose Asp, cyclooxygenase-2 inhibitors [coxibs], calcium, vitamin D, folic acid, ursodeoxycholic acid [UDCA], estrogen, and progesterone, alone or in combination) for preventing colorectal adenoma and CRC. Cochrane risk-of-bias assessment tool was employed to evaluate the quality of each included study. RESULTS Thirty-two randomized controlled trials (278,694 participants) comparing 13 different interventions were included. Coxibs significantly reduced the risk of colorectal adenoma (risk ratio [RR]: 0.59, 95% confidence interval [CI]: 0.44-0.79, six trials involving 5486 participants), advanced adenoma (RR: 0.63, 95% CI: 0.43-0.92, four trials involving 4723 participants), and metachronous adenoma (RR: 0.58, 95% CI: 0.43-0.79, five trials involving 5258 participants) compared with placebo. Coxibs also significantly increased the risk of severe adverse events (RR: 1.29, 95% CI: 1.13-1.47, six trials involving 7109 participants). Other interventions, including Asp, folic acid, UDCA, vitamin D, and calcium, did not reduce the risk of colorectal adenoma in the general and high-risk populations compared with placebo. CONCLUSIONS Considering the balance between benefits and harms, regular use of coxibs for prevention of colorectal adenoma was not supported by the current evidence. Benefit of low-dose Asp for chemoprevention of colorectal adenoma still requires further evidence. REGISTRATION PROSPERO, No. CRD42022296376.

Abstract
IMPORTANCE AND OBJECTIVE The menopausal hormone therapy (MHT) association with breast cancer has been controversial for more than 40 years. Most recently, findings from cohort studies have been discordant compared with those from the Women's Health Initiative (WHI) randomized trials. In cohort studies, both estrogen therapy and estrogen plus progestin were associated with higher breast cancer incidence. In contrast, in the WHI randomized trials, findings for estrogen plus progestin are concordant with cohort study reports, whereas estrogen therapy significantly reduced breast cancer incidence. In addition, concerns have been raised regarding the WHI findings from both trials. In this report, we briefly summarize findings for MHT on breast cancer from cohort studies and the WHI randomized trials. The report focus is addressing, point-by-point, concerns raised regarding the WHI findings. METHODS For cohort studies, we relied on the latest findings from (1) the meta-analysis of the Collaborative Group on Hormonal Factors in Breast Cancer and (2) the Million Women's Study. To identify commentaries and editorials, "Menopause" and "Climacteric" were searched from 2002 to present; PubMed and Google Scholar were searched for commentaries, editorials, and breast cancer, MHT, estrogen, conjugated equine estrogen, estradiol, "hormone replacement therapy," and "HRT." DISCUSSION AND CONCLUSIONS Thirty commentaries challenging WHI findings were identified. All were reviewed, and issues needing response were identified. Findings from the meta-analysis from the Collaborative Group on Hormonal Factors in Breast Cancer and the Million Women Study were summarized and compared with finding in the two WHI randomized trials evaluating estrogen therapy and estrogen plus progestin. Based on the randomized clinical trials, estrogen therapy, for women with prior hysterectomy, decreases breast cancer incidence and mortality. In contrast, estrogen plus progestin increases breast cancer incidence, which persists through two decades. Women considering estrogen plus progestin use for vasomotor symptoms should understand the breast cancer risk.

Abstract
PURPOSE OF REVIEW The menopause transition can be a time of great upheaval and suffering for some patients. Hormone replacement therapy (HRT) can relieve symptoms and improve quality of life but the perceived risks of HRT have decreased use over the past two decades. Understanding the real risks and benefits will ease physician and other healthcare professionals discomfort with counseling and prescribing this potentially life changing therapy in appropriate patients. RECENT FINDINGS Menopausal symptoms may persist several years beyond the final menstrual period. Previously stated risks of HRT overestimated the concern with menopausal therapy. New data indicates there are medical benefits to HRT beyond quality of life measures. SUMMARY In appropriate patients, the benefits of hormone replacement therapy outweigh the risks. Extended use of hormone replacement therapy is reasonable in patients with persistent symptoms.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the evidence on the benefits of menopausal hormone therapy (MHT) for the maintenance of skeletal health, prevention of osteoporosis and related fractures in peri and postmenopausal women. RECENT FINDINGS We will review the impact of estrogen on skeletal health as well as the physiology of bone loss during the perimenopause and postmenopause. We will then elucidate the data that include estrogen alone and combination of MHT to demonstrate that in the absence of contraindication, MHT should be considered as an option for the maintenance of skeletal health both when concomitant menopausal symptoms are present and when not. SUMMARY It has been well established that estrogens maintain bone mineral density (BMD) and reduce fracture risk at all sites. However, the most extensively studied form of estrogen with established fracture prevention is oral doses of synthetic estrogens. Due to the reduced risk profile, lower doses of bioidentical oral or transdermal estrogens are often preferred in clinical practice. We will highlight the current data on improvement in BMD and fracture risk reduction, including differences in formulation, dose, and route of delivery, to support a provider in the clinical decision-making process.

Abstract
Ambient air pollution has been associated with bone damage. However, no studies have evaluated the metabolomic response to air pollutants and its potential influence on bone health in postmenopausal women. We analyzed data from WHI participants with plasma samples. Whole-body, total hip, femoral neck, and spine BMD at enrollment and follow-up (Y1, Y3, Y6). Daily particulate matter NO, NO2, PM10 and SO2 were averaged over 1-, 3-, and 5-year periods before metabolomic assessments. Statistical analyses included multivariable-adjusted linear mixed models, pathways analyses, and mediation modeling. NO, NO2, and SO2, but not PM10, were associated with taurine, inosine, and C38:4 phosphatidylethanolamine (PE), at all averaging periods. We found a partial mediation of C38:4 PE in the association between 1-year average NO and lumbar spine BMD (p-value: 0.032). This is the first study suggesting that a PE may partially mediate air pollution-related bone damage in postmenopausal women.

Abstract
Anti-resorptive therapy (AT) increases insulin resistance and decrease insulin secretion through reduced undercarboxylated osteocalcin in mice. However, there are inconsistent findings regarding the impact of AT use on the risk of diabetes mellitus in humans. We examined the association between AT and incident diabetes mellitus using classical and Bayesian meta-analysis. We searched Pubmed, Medline, Embase, Web of Science, Cochrane, and Google Scholar for studies listed from database inception to 25 February 2022. Randomized controlled trials (RCTs) and cohort studies reporting associations of estrogen therapy (ET) and non-estrogen anti-resorptive therapy (NEAT) with incident diabetes mellitus were included. Two reviewers independently extracted research data such as ET and NEAT, diabetes mellitus, risk ratios (RRs), and 95 % confidence intervals (CIs) for incident diabetes mellitus associated with ET and NEAT from individual studies. This meta-analysis included data from nineteen original studies, consisting of fourteen ET and five NEAT studies. ET was associated with reduced risk of diabetes mellitus in the classical meta-analysis (RR: 0.90; 95 % CI: 0.81-0.99). Slightly stronger results were found in the meta-analysis of RCTs (RR: 0.83; 95 % CI: 0.77-0.89). The probability that RR < 1.0 was 95 % in the overall analysis and 99 % in RCTs under weakly informative prior. Although NEAT was associated with reduced risk of diabetes mellitus overall (RR: 0.80; 95 % CI: 0.67-0.97), this was not found in the RCT meta-analysis (RR: 0.90; 95 % CI: 0.75-1.10). Under weakly informative prior, the probabilities that NEAT reduces diabetes mellitus by >0 % were 99 %, and 73 % in the overall and RCT meta-analysis, respectively. In conclusion, meta-analysis provided consistent evidence against the hypothesis that AT increases diabetes risk. ET may reduce the risk of diabetes mellitus. Whether NEAT reduces the risk of diabetes mellitus is uncertain and requires additional evidence from RCTs.

Abstract
Loss of estrogen, as occurs with normal aging, leads to increased inflammation, pathologic angiogenesis, impaired mitochondrial function, and microvascular disease. While the influence of estrogens on purinergic pathways is largely unknown, extracellular adenosine, generated at high levels by CD39 and CD73, is known to be anti-inflammatory in the vasculature. To further define the cellular mechanisms necessary for vascular protection, we investigated how estrogen modulates hypoxic-adenosinergic vascular signaling responses and angiogenesis. Expression of estrogen receptors, purinergic mediators inclusive of adenosine, adenosine deaminase (ADA), and ATP were measured in human endothelial cells. Standard tube formation and wound healing assays were performed to assess angiogenesis in vitro. The impacts on purinergic responses in vivo were modeled using cardiac tissue from ovariectomized mice. CD39 and estrogen receptor alpha (ERα) levels were markedly increased in presence of estradiol (E2). Suppression of ERα resulted in decreased CD39 expression. Expression of ENT1 was decreased in an ER-dependent manner. Extracellular ATP and ADA activity levels decreased following E2 exposure while levels of adenosine increased. Phosphorylation of ERK1/2 increased following E2 treatment and was attenuated by blocking adenosine receptor (AR) and ER activity. Estradiol boosted angiogenesis, while inhibition of estrogen decreased tube formation in vitro. Expression of CD39 and phospho-ERK1/2 decreased in cardiac tissues from ovariectomized mice, whereas ENT1 expression increased with expected decreases in blood adenosine levels. Estradiol-induced upregulation of CD39 substantially increases adenosine availability, while augmenting vascular protective signaling responses. Control of CD39 by ERα follows on transcriptional regulation. These data suggest novel therapeutic avenues to explore in the amelioration of post-menopausal cardiovascular disease, by modulation of adenosinergic mechanisms.

Abstract
IMPORTANCE AND OBJECTIVE Addressing the hormonal needs of individuals at increased risk of breast cancer (BC) can be a challenge. Observational, prospective, and case-control data support the safety of hormonal contraception in women, often with the added benefits of ovarian and endometrial cancer risk reduction. The majority of data on menopausal hormone therapy (HT) in the highest-risk patients comes from studies of patients with pathogenic variants in BRCA1 and BRCA2 who undergo early surgical menopause. The benefits of risk-reducing salpingo-oophorectomy are not minimized by HT, whereas its use mitigates accelerated osteoporosis and cardiovascular disease. In other patients at increased risk, such as with family history, studies have shown little risk with significant benefit. METHODS We review evidence to help women's health practitioners aid patients in making choices. The paper is divided into four parts: 1, contraception in the very high-risk patient (ie, with a highly penetrant BC predisposition gene); 2, contraception in other patients at increased risk; 3, menopausal HT in the gene carrier; and 4, HT in other high-risk patients. DISCUSSION AND CONCLUSION Women at increased risk for BC both early and later in life should be offered reassurance around the use of premenopausal and postmenopausal hormone therapies. The absolute risks associated with these therapies are low, even in the very high-risk patient, and the benefits are often substantial. Shared decision making is key in presenting options, and knowledge of the data in this area is fundamental to these discussions.

Abstract
PURPOSE This study aimed to develop hyaluronic acid (HA)-based, retinoic acid (RA)-containing nanomicelles and to investigate the effects of these newly developed nanomicelles on regeneration of the vaginal epithelium and aquaporin 3 (AQP3) expression in a murine menopause model. MATERIALS AND METHODS The HA-based, RA-loaded nanomicelles were developed, and the RA-loading rate, encapsulation efficiency, and hydrodynamic diameter were measured. Female BALB/c mice (8 weeks; n=30) were divided into control and experimental groups. Menopause was established in the experimental group by removing both ovaries. The experimental group was further divided into an ovariectomy group, an HA-C18 vehicle group, and an HA-C18-RA group (2.5 µg per mouse); vaginal administration of HA-C18 or HA-C18-RA was performed once daily. After 4 weeks of treatment, murine vaginal tissue was removed, and histological analysis was performed. RESULTS Three drug-loaded nanomicelles were synthesized: the RA content in HA-C18-RA-10, HA-C18-RA-20, and HA-C18-RA-30 was 3.13%, 2.52%, and 16.67%, respectively, and the RA encapsulation efficiency was 95.57%, 83.92%, and 93.24%, respectively. In the experimental versus control group, serum estrogen levels were significantly reduced, and the vaginal mucosal epithelial layer was significantly thinner. After 4 weeks of treatment, the thickness of the vaginal mucosal epithelial layer and AQP3 expression was increased in the HA-C18-RA group compared with the HA-C18 vehicle group. CONCLUSIONS The newly developed HA-based nanomicelles containing RA resulted in vaginal epithelial recovery and increased AQP3 expression. The results may contribute to the development of functional vaginal lubricants or moisturizers for the treatment of vaginal dryness.

Abstract
Menopause, which is defined as the point in time 12 months after a woman's final menstrual period, is marked by a decrease in estrogen and accompanying symptoms including vasomotor and genitourinary symptoms. Hormone therapy is the most effective treatment of vasomotor symptoms and is first-line in women with moderate-to-severe vasomotor symptoms who are early in the menopausal transition and do not have a contraindication. Nonhormonal pharmacologic and nonpharmacologic treatments are also available for the treatment of menopause-related symptoms for women who prefer to avoid hormones or who have a contraindication to hormone therapy.

Abstract
Physical fitness is a well-known correlate of health and the aging process and DNA methylation (DNAm) data can capture aging via epigenetic clocks. However, current epigenetic clocks did not yet use measures of mobility, strength, lung, or endurance fitness in their construction. We develop blood-based DNAm biomarkers for fitness parameters gait speed (walking speed), maximum handgrip strength, forced expiratory volume in one second (FEV1), and maximal oxygen uptake (VO2max) which have modest correlation with fitness parameters in five large-scale validation datasets (average r between 0.16-0.48). We then use these DNAm fitness parameter biomarkers with DNAmGrimAge, a DNAm mortality risk estimate, to construct DNAmFitAge, a new biological age indicator that incorporates physical fitness. DNAmFitAge is associated with low-intermediate physical activity levels across validation datasets (p = 6.4E-13), and younger/fitter DNAmFitAge corresponds to stronger DNAm fitness parameters in both males and females. DNAmFitAge is lower (p = 0.046) and DNAmVO2max is higher (p = 0.023) in male body builders compared to controls. Physically fit people have a younger DNAmFitAge and experience better age-related outcomes: lower mortality risk (p = 7.2E-51), coronary heart disease risk (p = 2.6E-8), and increased disease-free status (p = 1.1E-7). These new DNAm biomarkers provide researchers a new method to incorporate physical fitness into epigenetic clocks.

Int J Mol Sci 2023; 24:ijms24044123.

Abstract
Recent studies suggest estradiol (E2)/natural progesterone (P) confers less breast cancer risk compared with conjugated equine estrogens (CEE)/synthetic progestogens. We investigate if differences in the regulation of breast cancer-related gene expression could provide some explanation. This study is a subset of a monocentric, 2-way, open observer-blinded, phase 4 randomized controlled trial on healthy postmenopausal women with climacteric symptoms (ClinicalTrials.gov; EUCTR-2005/001016-51). Study medication was two 28-day cycles of sequential hormone treatment with oral 0.625 mg CEE and 5 mg of oral medroxyprogesterone acetate (MPA) or 1.5 mg E2 as percutaneous gel/day with the addition of 200 mg oral micronized P. MPA and P were added days 15-28/cycle. Material from two core-needle breast biopsies in 15 women in each group was subject to quantitative PCR (Q-PCR). The primary endpoint was a change in breast carcinoma development gene expression. In the first eight consecutive women, RNA was extracted at baseline and after two months of treatment and subjected to microarray for 28856 genes and Ingenuity Pathways Analysis (IPA) to identify risk factor genes. Microarray analysis showed 3272 genes regulated with a fold-change of >±1.4. IPA showed 225 genes belonging to mammary-tumor development function: 198 for CEE/MPA vs. 34 for E2/P. Sixteen genes involved in mammary tumor inclination were subject to Q-PCR, inclining the CEE/MPA group towards an increased risk for breast carcinoma compared to the E2/P group at a very high significance level (p = 3.1 × 10-8, z-score 1.94). The combination of E2/P affected breast cancer-related genes much less than CEE/MPA.

Abstract
Menopausal hormone therapy (HT) was widely used in the past, but with the publication of seminal primary and secondary prevention trials that reported an excess cardiovascular risk with combined estrogen-progestin, HT use declined significantly. However, over the past 20 years, much has been learned about the relationship between the timing of HT use with respect to age and time since menopause, HT route of administration, and cardiovascular disease risk. Four leading medical societies recommend HT for the treatment of menopausal women with bothersome menopausal symptoms. In this context, this review, led by the American College of Cardiology Cardiolovascular Disease in Women Committee, along with leading gynecologists, women's health internists, and endocrinologists, aims to provide guidance on HT use, including the selection of patients and HT formulation with a focus on caring for symptomatic women with cardiovascular disease risk.

Abstract
Vasomotor symptoms affect as many as 80% of midlife women, but only about one in four women receive treatment due to many factors. Menopausal hormone therapy remains the most effective treatment for vasomotor symptoms, and current professional guidelines conclude that the benefits of treatment typically outweigh the risks for healthy, symptomatic women under age 60 years and those within 10 years from their final menstrual period. For women with medical comorbidities, an individualized approach to treatment is recommended. For women who cannot use or choose not to use menopausal hormone therapy, there are many evidence-based non-hormonal options available including pharmacologic therapies. This review aims to summarize treatment options for bothersome vasomotor symptoms to guide clinicians caring for midlife women.

Abstract
IMPORTANCE Menopause, due to loss of ovarian follicular activity without another pathological or physiological cause, typically occurs between the ages of 45 years and 56 years. During the menopausal transition, approximately 50% to 75% of women have hot flashes, night sweats, or both (vasomotor symptoms) and more than 50% have genitourinary symptoms (genitourinary syndrome of menopause [GSM]). OBSERVATIONS Vasomotor symptoms typically last more than 7 years and GSM is often chronic. Efficacious treatments for women with bothersome vasomotor symptoms or GSM symptoms include hormonal and nonhormonal options. Systemic estrogen alone or combined with a progestogen reduces the frequency of vasomotor symptoms by approximately 75%. Oral and transdermal estrogen have similar efficacy. Conjugated equine estrogens (CEE) with or without medroxyprogesterone acetate (MPA) were the only hormonal treatments for which clinical trials were designed to examine cardiovascular events, venous thromboembolism, and breast cancer risk. Compared with placebo, the increased risk of stroke and venous thromboembolism associated with CEE (with or without MPA) and breast cancer (with use of CEE plus MPA) is approximately 1 excess event/1000 person-years. Low-dose CEE plus bazedoxifene is not associated with increased risk of breast cancer (0.25%/year vs 0.23%/year with placebo). Bioidentical estrogens approved by the US Food and Drug Administration (with identical chemical structure to naturally produced estrogens, and often administered transdermally) also are available to treat vasomotor symptoms. For women who are not candidates for hormonal treatments, nonhormonal approaches such as citalopram, desvenlafaxine, escitalopram, gabapentin, paroxetine, and venlafaxine are available and are associated with a reduction in frequency of vasomotor symptoms by approximately 40% to 65%. Low-dose vaginal estrogen is associated with subjective improvement in GSM symptom severity by approximately 60% to 80%, with improvement in severity by 40% to 80% for vaginal prasterone, and with improvement in severity by 30% to 50% for oral ospemifene. CONCLUSIONS AND RELEVANCE During the menopausal transition, approximately 50% to 75% of women have vasomotor symptoms and GSM symptoms. Hormonal therapy with estrogen is the first-line therapy for bothersome vasomotor symptoms and GSM symptoms, but nonhormonal medications (such as paroxetine and venlafaxine) also can be effective. Hormone therapy is not indicated for the prevention of cardiovascular disease.

Abstract
It is increasingly thought that part of human susceptibility to cancer is the result of evolutionary mismatches: our ancestors evolved cancer suppression mechanisms in a world largely different from our modern environments. In that context, it has been shown in cohorts from general Western populations that reproductive traits modulate breast cancer risk. Overall, the more menses women experience, the more at risk they are to develop postmenopausal breast cancer. This points towards an evolutionary mismatch but brings the question whether the reproductive pattern also modulates the breast cancer risk in menopausal women at high familial risk. We thus studied the influence of menses on breast cancer risk in a case–control study of 90 postmenopausal women (including BRCA1/2 and non BRCA1/2) nested within a cohort at high familial risk. We tested the association of the lifetime number of menses and the number of menses before first full-term pregnancy with postmenopausal breast cancer risk using Cox survival models. We showed that the total lifetime number of menses was significantly associated with postmenopausal breast cancer risk and associated with a quicker onset of breast cancer after menopause. Those results align with similar studies lead in general cohorts and suggest that the reproductive pattern modulates the familial risk of developing breast cancer after menopause. Altogether, those results impact how we envision breast cancer prevention and call for more research on how ecological and genetic factors shape breast cancer risk.

Abstract
OBJECTIVE To document health care providers' views regarding treatments for symptoms associated with menopause and discussions with patients about symptoms and treatment decisions. Results informed development of a data collection form for a retrospective medical record review (reported separately). METHODS Registered US gynecologists or primary care providers from all US regions were identified from local association directories and an in-house database and were invited to participate in a qualitative interview if they consulted with three or more patients per week presenting with menopausal symptoms. Participants provided demographic data, information about patients' symptoms, and health care provider and patient views on prescription and nonprescription therapies. Key concepts/themes from interviews were identified. RESULTS Participating health care providers (10 gynecologists, 10 primary care providers) agreed there are effective treatment options for menopausal symptoms, particularly vasomotor symptoms and vaginal dryness and/or atrophy. Health care providers reported that treatment was generally dictated by symptoms that interfered with quality of life and/or daily activities, although patients often had symptoms for months before presentation. All health care providers said they prescribe hormone and/or nonhormone therapies for treatment of menopausal symptoms; half stated that they typically inquire about patients' nonprescription therapy use, and 45% recommend specific nonprescription therapies. The most commonly cited barriers to initiation of any therapy for menopausal symptoms were patient concerns about risks and financial considerations (ie, insurance or cost). CONCLUSIONS US health care providers reported prescribing therapies for menopausal symptoms and noted that these therapies were perceived as generally effective; however, barriers to initiation of prescription therapy exist, and new treatment options are needed.

Abstract
Given the aging population, with a peak age-specific prevalence that is shifting beyond the age of 50, several women currently living with MS are very close to menopause. Menopause is usually characterized by several specific symptoms with adverse impacts on different aspects of a woman's quality of life, such as fatigue, and cognitive, mood and bladder disorders, which overlap with symptoms of MS. Generally, after this biological transition, women with MS appear to be subject to less inflammatory activity. However, several studies have reported an increase of disability accumulation after menopause, suggesting that it is a turning point to a more progressive phase of the disease. This may be attributable to the hormonal and immunological changes associated with menopause, with several effects on neuroinflammation and neurodegeneration increasing due to the immunosenescence of aging. This review summarizes the hormonal and immunological changes associated with menopause, detailing the effects on MS symptoms, outcomes, and the aging process. Furthermore, possible interventions to improve patients' quality of life are evaluated. In fact, it is increasingly necessary to improve the global management of MS women, as well as their lives, at this multifaceted turning point.

Abstract
PURPOSE This study aimed to assess the association between hormone replacement therapy (HRT) and the prevalence of nonarteritic anterior ischemic optic neuropathy (NAION) in menopausal women using national data from the entire Korean population. METHODS The health screening data of 1,381,605 women between 40 and 90 years of age collected by the National Health Insurance Service (NHIS) of Korea between January 1, 2009, and December 31, 2018, were retrospectively reviewed. Before data analysis, the potential cofounders were adjusted for among all participants. Based on HRT use and its duration (classified into four groups), the hazard ratio (HR) and 95% confidence interval (CI) of NAION development were calculated via a Cox proportional hazards regression analysis using the nonuser group as a reference. RESULTS Overall, 7824 NAION diagnoses were made during the mean follow-up of 8.22 years (standard deviation: 1.09 years) in 1,381,605 post-menopausal women. NAION was more common in the HRT group than in the non-HRT group (HR [95% CI]: 1.268 [1.197-1.344]). Furthermore, the risk of NAION increased along with increased HRT duration (p < 0.0001). In the multivariate analysis, the adjusted HRs of the < 2-year HRT group, the 2-5-year HRT group, and the ≥ 5-year HRT group were 1.19 (95% CI: 1.10-1.28), 1.3 (95% CI: 1.17-1.45), and 1.473 (95% CI: 1.31-1.65), respectively. Compared to women younger than 65 years, the HR of HRT for NAION was significantly higher than that of women older than 65 years (p < 0.0001). CONCLUSION Our population-based cohort study found that HRT was significantly associated with increased incidence of NAION. The incidence of NAION also increased with the duration of HRT.

Abstract
Weighing risks and benefits of postmenopausal hormone therapy (HT) has proven a balancing act. We aimed to investigate the association between HT and mortality before and after the 2002 publication from the Women's Health Initiative (WHI) study. This publication found that the risk of using HT outweighted the benefits, and thus it caused a marked reduction in systemic HT user prevalence. The 2002 WHI publication may also have caused a change in the subsequent HT user profile, as HT is no longer recommended in the prevention of chronic diseases. This cohort study included two populations followed from 1995: A 5% random sample of female singletons from the Danish general population (n = 52,388) and a sample of Danish female twins (n = 15,261). HT use was evaluated in 1995, 2000, 2005, and 2010. The association between HT, education, and mortality was investigated and controlled for potential unobserved familial confounding in a within-pair analysis. Singletons aged 56-75 using systemic HT in 2000 had a lower mortality compared to non-users (hazard ratio (HR) 0.83, 95% confidence interval (CI) 0.78-0.89). In 2005, the mortality was like that of the background population for this age group (HR 1.02, 95% CI 0.94-1.11). Recently postmenopausal twins showed a similar tendency. Systemic HT users, who had switched to local HT by 2005, had a substantially lower mortality than non-users (HR ranging from 0.42 to 0.67 depending on age group). In conclusion, we found that the prevalence of systemic HT use declined after 2002, and systemic HT users' mortality changed from lower before 2002 to similar to that of the background population after 2002. This indicates that the healthiest users decided to either drop systemic HT or switcted to local HT, as recommendations changed following the WHI publication.

Abstract
Background: Frequently, patients treated for Ovarian Cancer (OC) undergo menopause with subsequent symptoms. This review scrutinised the impact of Hormone Replacement Therapy (HRT) on the Overall Survival (OS) and Progression-Free Survival (PFS) of patients diagnosed with OC. Methods: A systematic literature search was conducted in the most popular English databases. Inclusion and exclusion criteria were applied to select publications that evaluate OS and PFS in these patients. End-point analysis targeted values of log(HR) and its Standard Error (SE). Results: Up to 1 September 2022, 11 studies were included in the qualitative synthesis. Eight publications, totalling 4191 patients, were included in the meta-analyses. Eight studies were considered for the OS analysis and pooled an HR of 0.66 with respective 95% CI between 0.57 and 0.76, with a p-value < 0.00001 at a Z value of 5.7, in favour of the HRT group. Results for PFS showed an overall HR of 0.73 in favour of the HRT group; CI between 0.57 and 0.95, p = 0.02 at a Z value of 2.36. Further subgroup analyses highlighted the non-inferiority of this treatment. Conclusions: Patients treated for OC that receive HRT for menopausal symptoms after various treatments appeared to have better OS than never-users.

Abstract
BACKGROUND Although colonoscopy is considered the most effective tool for reducing colorectal cancer-related morbidity, the age at which average-risk individuals begin colonoscopic screening is undetermined. This study aimed to compare the adenoma and advanced adenoma detection rates according to age and sex in a large average-risk population in the rural areas of Eastern China. METHODS This observational, single-center, retrospective study included patients with average colorectal cancer risk and examined the adenoma and advanced adenoma detection rates using age intervals of 5 years. We also compared the size and age of patients with and without advanced adenoma. RESULTS We included 18 928 patients with a median age of 54 years (range 15-90 years), including 10 143 men and 8785 women. The adenoma and advanced adenoma detection rates were 17.08% and 5.24%, respectively, and increased with age in the whole population. The adenoma detection rates increased from 8.97% (aged 40-44) to 14.98% (aged 45-49) and 6.24% (aged 45-49) to 11.00% (aged 50-54) in men and women (both P < .001), respectively. The advanced adenoma detection rates increased from 2.19% (aged 40-44) to 4.76% (aged 45-49) and 1.89% (aged 45-49) to 3.13% (aged 50-54) in men (P = .002) and women (P = .056), respectively. Patients with advanced adenomas were significantly older than those with non-advanced adenomas (P < .001). The tumors in the advanced adenoma group were significantly larger than those in the non-advanced adenoma group (P < .001). CONCLUSION The adenoma and advanced adenoma detection rates increased significantly in average-risk population aged 45 years and older, especially in men.

The association of hormone therapy with blood pressure control in postmenopausal women with hypertension: a secondary analysis of the Women's Health Initiative clinical trials. Menopause 2023; 30:28-36.

Abstract
OBJECTIVE The objective of this study was to assess the effect of menopausal hormone therapy (HT) on blood pressure control in postmenopausal women with hypertension. METHODS The Women's Health Initiative HT clinical trials were double-blinded, randomized, placebo-controlled studies of women aged 50 to 79 years testing the effects of HT (conjugated equine estrogens [CEE, 0.625 mg/d] or CEE + medroxyprogesterone acetate [MPA; 2.5 mg/d]) on risks for coronary heart disease and invasive breast cancer, the primary outcomes for efficacy and safety, respectively. This secondary analysis of the Women's Health Initiative HT trials examined a subsample of 9,332 women with hypertension (reported ever taking pills to treat hypertension or were taking antihypertensive medication) at baseline. Blood pressure was measured at baseline and up to 10 annual follow-up visits during the planned study phase. Antihypertensive medications were inventoried at baseline and years 1, 3, 6, and 9 during the study, and self-reported during extended follow-up: 2009-2010 and 2012-2013, which occurred median of 13 and 16 years after randomization, respectively. The intervention effect was estimated through year 6. Cumulative follow-up included all visits. RESULTS Compared with placebo, CEE-alone had significantly ( P = 0.02) higher systolic blood pressure (SBP) by mean (95% confidene interval [CI]) = 0.9 (0.2-1.5) mm Hg during the intervention phase. For cumulative follow-up, the CEE arm was associated with increased SBP by mean (95% CI) = 0.8 (0.1-1.4) mm Hg ( P = 0.02). Furthermore, CEE + MPA relative to placebo was associated with increased SBP by mean (95% CI) = 1.8 (1.2-2.5) mm Hg during the intervention phase ( P < 0.001). For cumulative follow-up, the CEE + MPA arm was associated with increased SBP by mean (95% CI) = 1.6 (1.0-2.3) mm Hg ( P < 0.001). The mean number of antihypertensive medications taken at each follow-up visit did not differ between randomization groups during the intervention or long-term extended follow-up of 16 years. CONCLUSION There was a small but statistically significant increase in SBP in both CEE-alone and CEE + MPA arms compared with placebo during both the intervention and cumulative follow-up phases among postmenopausal women with hypertension at baseline. However, this increase in SBP was not associated with an increased antihypertensive medication use over time among women randomized to HT compared with placebo.

Abstract
For post-menopausal women, stroke is complicated by the variable effects of estrogen therapy and the age-related therapeutic consequences involved. Estrogen therapy has been shown to have an age-dimorphic effect, which is neuroprotective in young females, but non-neuroprotective, even neurotoxic in acyclic females. We hypothesized that arterial baroreflex (ABR) and its downstream acetylcholine-α7 nicotinic acetylcholine receptor (α7nAChR) anti-inflammatory pathways are involved in estrogen efficacy toward cerebral ischemic damage. Our data showed that estrogen supplements contributed to ABR improvement and neuroprotection in adult, not aged, ovariectomized (OVX) rats. In adult rats, OVX-induced estrogen deficiency aggravated middle cerebral artery occlusion (MCAO), which induced brain infarction and reduced ABR function, with decreased α7nAChR expression of the brain and exaggerated inflammation following MCAO; these effects were significantly prevented by supplementation with estrogen. ABR impairment by sinoaortic denervation partly attenuated the estrogen effect on baroreflex sensitivity (BRS) and ischemic damage in adult rats, as well as α7nAChR expression and inflammatory response. These data suggested that ABR and acetylcholine-α7nAChR anti-inflammatory pathways are involved in the neuroprotection of estrogen in adult OVX rats. In contrast, aged rats exhibited more severe ischemic damage and inflammatory response than adult rats, as well as poorer baroreflex function and lower α7nAChR expression. Estrogen supplements did not improve BRS or confer neuroprotection in aged rats without affecting brain α7nAChR and post-ischemic inflammation. Most importantly, ketanserin restored ABR function and significantly postponed the onset of stroke in aged female strokeprone spontaneously hypertensive rats, whereas estrogen treatment failed to delay the development of stroke. Our findings reveal that estrogen is protective against ischemic stroke (IS) in adult female rats and that ABR played a role in this beneficial action. Dysfunction of ABR and unresponsiveness to estrogen in aged female rats may contribute to a reduced estrogen efficacy against cerebral ischemia.

Abstract
Stroke is a particularly important issue for women. Women account for over half of all persons who experienced a stroke. The lifetime risk of stroke is higher in women than in men. In addition, women have worse stroke outcomes than men. Several risk factors have a higher association with stroke in women than in men, and women-specific risk factors that men do not have should be considered. This focused review highlights recent findings in stroke epidemiology, risk factors, and outcomes in women.

Abstract
Oxyresveratrol (OXY) is a naturally occurring phenolic compound; however, there are no toxicity studies reported on its long term use. The aim of our work was to demonstrate the evaluation of acute and sub-chronic toxicity of oxyresveratrol in rats to assess its safety profile. To evaluate the LD50 value, 2000 mg/kg of oxyresveratrol was administered to Wistar rats by oral gavage. For sub-chronic toxicity assessment, 80 Wistar rats were randomly divided into four groups (10 animal/sex/group) and oxyresveratrol administered at a dose of 50, 100, 150 mg/kg/day by oral gavage. Bodyweight, food, and water consumption were monitored every week. At the end of the experiments, biochemical and hematological parameters were analyzed. Gross and microscopic organ analyses were also carried out. LD50 of oxyresveratrol was greater than 2000 mg/kg sub-chronic administration of oxyresveratrol did not influence any mortality. Doses of 50 and 100 mg/kg of oxyresveratrol did not produce any sign of toxicity. However, the 150 mg/kg oxyresveratrol group depicted changes in multiple biochemical and hematological parameters with changes in the pathology of cardiac, hepatic, and renal tissues when compared with control. Therefore, no observed adverse effect level (NOAEL) of oxyresveratrol was observed to be 100 mg/kg per day for both male and female rats.
