Peculiarities of local immunity in dry eye disease on the background of hormonal dysfunction.

OBJECTIVE: Aim: to determine the state of local immunity in DED on the background of hormonal dysfunction. PATIENTS AND METHODS: Materials and Methods: Of 32 women, 17 patients with diagnosed SM and 15 women of the control group were examined. The Ocular Surface Disease Index and the state of local immunity were defined by determining Ig As in lacrimal fluid (LF) by radial immunodiffusion in Mancini agar. RESULTS: Results: During the OSDI questionnaire, a mild degree of DED was detected in 21 (65.6%) women, and an average degree was observed in 11 (34.4%) patients with SM. On average, OSDI was 34.54 ±2.01. As a result of studies of the state of local immunity in patients with SM, a tendency to increase Ig As was noted, compared with the control group. An increase in Ig As in the lacrimal fluid in patients with SM to 0.34 ±0.09 g/l was found, compared with the control group (0.24 ±0.03 g/l). CONCLUSION: Conclusions: Using the OSDI questionnaire, the presence of DED was detected in women with SM, mainly mild and moderate degree. The obtained results of the state of local immunity indicate in favor of a nonspecific inflammatory process, accompanied by a decrease in local immune protection and leading to further changes in the ocular surface.

17ß-Estradiol protects female rats from bilateral oophorectomy-induced nonalcoholic fatty liver disease induced by improving linoleic acid metabolism alteration and gut microbiota disturbance.

After surgical or natural menopause, women face a high risk of nonalcoholic fatty liver disease (NAFLD), which can be diminished by hormone replacement therapy (HRT). The gut microbiota is subject to modulation by various physiological changes and the progression of diseases. This microbial ecosystem coexists symbiotically with the host, playing pivotal roles in immune maturation, microbial defense mechanisms, and metabolic functions essential for nutritional and hormone homeostasis. E2 supplementation effectively prevented the development of NAFLD after bilateral oophorectomy (OVX) in female rats. The changes in the gut microbiota such as abnormal biosynthetic metabolism of fatty acids caused by OVX were partially restored by E2 supplementation. The combination of liver transcriptomics and metabolomics analysis revealed that linoleic acid (LA) metabolism, a pivotal pathway in fatty acids metabolism was mainly manipulated during the induction and treatment of NAFLD. Further correlation analysis indicated that the gut microbes were associated with abnormal serum indicators and different LA metabolites. These metabolites are also closely related to serum indicators of NAFLD. An in vitro study verified that LA is an inducer of hepatic steatosis. The changes in transcription in the LA metabolism pathway could be normalized by E2 treatment. The metabolic perturbations of LA may directly and secondhand impact the development of NAFLD in postmenopausal individuals. This research focused on the sex-specific pathophysiology and treatment of NAFLD, providing more evidence for HRT and calling for the multitiered management of NAFLD.

Genitourinary symptoms and sexual function in women with primary ovarian insufficiency.

OBJECTIVE: There are limited studies on urogenital symptoms in women who experience menopause before the age of 40 years due to primary ovarian insufficiency (POI) or bilateral oophorectomy (surgical POI). This study aimed to compare the urogenital symptoms, including sexuality, of women with POI to those without the condition. METHODS: This cross-sectional study conducted was in seven Latin American countries, in which postmenopausal women (with POI and non-POI) were surveyed with a general questionnaire, the Menopause Rating Scale (MRS) and the six-item Female Sexual Function Index (FSFI-6). The association of premature menopause with more urogenital symptoms and lower sexual function was evaluated with logistic regression analysis. RESULTS: Women with POI experience more urogenital symptoms (MRS urogenital score: 3.54 ± 3.16 vs. 3.15 ± 2.89, p < 0.05) and have lower sexual function (total FSFI-6 score: 13.71 ± 7.55 vs. 14.77 ± 7.57 p < 0.05) than women who experience menopause at a normal age range. There were no significant differences in symptoms when comparing women based on the type of POI (idiopathic or surgical). After adjusting for covariates, our logistic regression model determined that POI is associated with more urogenital symptoms (odds ratio [OR]: 1.38, 95% confidence interval [CI] 1.06-1.80) and lower sexual function (OR: 1.67, 95% CI 1.25-2.25). CONCLUSION: POI, whether idiopathic or secondary to bilateral oophorectomy, is associated with symptoms that affect vaginal and sexual health.

Evaluation of the risk of thyroid cancer following hysterectomy through meta-analysis.

OBJECTIVES: Thyroid cancer is observed more frequently in women than men, possibly due to the influence of hormonal factors. This study aims to conduct a meta-analysis encompassing both prospective and retrospective observational studies to examine the risk of thyroid cancer in women who have undergone hysterectomy surgery. MATERIAL AND METHODS: The literature search identified 356 articles by May 2022, and eight reported hazard ratios for thyroid cancer in women who underwent hysterectomy surgery. After the eliminations, we performed three different meta-analyses with studies that included patients who underwent only total abdominal hysterectomy (TAH), total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH and BSO), and underwent hysterectomy with or without BSO. The reporting of this study has been conducted in accordance with the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (Assessing the Methodological Quality of Systematic Reviews). RESULTS: Our study showcases a comprehensive meta-analysis that includes eight observational studies, both retrospective and prospective, exploring the link between hysterectomy and the likelihood of developing thyroid cancer. This analysis is based on data from more than 12 million individuals, encompassing over 24,000 cases. Women who had undergone TAH (HR = 1.586, 95% CI: 1.382-1.819, p < 0.001), women who had undergone TAH and BSO (HR = 1.420, 95% CI: 1.205-1.675, p < 0.001), and women who had undergone hysterectomy with or without BSO had an increased risk (HR = 1.623, 95% CI: 1.387-1.899, p < 0.001) of developing thyroid cancer later in life. CONCLUSIONS: We found that hysterectomy had a statistically significant risk effect on the development of thyroid cancer. The limited number of previous studies, the low amount of information, the lack of homogeneous distribution of the patients in the studies, and the unknown characteristics of thyroid cancer developing after hysterectomy were the limitations of this study. Nevertheless, our findings can positively affect public health because of the potential to enlighten the etiological mechanisms leading to thyroid cancer. Future researches should first aim to explain the underlying mechanisms of developing thyroid cancer after hysterectomy.

Recurrent Serous Borderline Tumor After Fertility-Sparing Surgery Following Twin Pregnancy and Resumption of Menstruation.

Gynecologic malignancies sometimes affect women before menopause. Aggressive treatments, such as surgery, chemotherapy, and/or radiotherapy, often lead to premature menopause. Hormone replacement therapy (HRT), typically used for managing menopause-associated health issues, may be limited by tumor sensitivity to estrogen. Here, we present a case of a 37-year-old woman seeking fertility, who was diagnosed with a serous borderline ovarian tumor (BOT). Fertility-preserving surgery and in-vitro fertilization resulted in a twin pregnancy. During a postpartum amenorrheic period, there was no recurrence. However, she experienced a rapid recurrence of the disease following the resumption of menstruation and underwent radical surgery. This rapid recurrence after menstruation resumed suggests potential estrogen sensitivity. Close postoperative monitoring has been ongoing without HRT.

Ovarian Insufficiency: Clinical Spectrum and Management Challenges.

The term "ovarian insufficiency" describes the decline of ovarian function resulting in fertility loss and the marked decrease of ovarian steroid hormone production. From a clinical standpoint, ovarian insufficiency presents in three different settings. The first is natural menopause at midlife occurring at the average age of 51 years. The second arises after surgical oophorectomy owing to disease or elective cancer prophylaxis. Finally, primary or premature ovarian insufficiency is characterized by menopause occurring before age 40, often of undetermined etiology, but at times linked with genetic mutations, autoimmune syndromes, metabolic conditions, iatrogenic etiologies, and toxic exposures. Each clinical situation presents unique concerns and management challenges. The majority of women with intact ovaries who live to age 51 experience natural menopause, with early menopause <45 years. In the United States, surgical menopause with bilateral oophorectomy occurs in ∼600,000 women per year. The timing and specific clinical indication for oophorectomy alters management. Primary ovarian insufficiency occurs in 1% of women, although recent estimates suggest the prevalence may be increasing. Symptoms of ovarian insufficiency include hot flashes or vasomotor symptoms, mood disorders, sleep disruption, and vaginal/urinary symptoms. Health concerns include bone, cardiovascular, and cognitive health. Management of symptoms and preventive strategies varies depending upon the age, clinical situation, and specific health concerns of each individual. Treatment options for symptom relief include cognitive behavior therapy and hypnosis, nonhormonal prescription therapies, and hormone therapy. Tailoring the therapeutic approach over time in response to age, emerging medical issues, and patient desires constitutes individualized care.

Premature ovarian insufficiency, early menopause, and induced menopause.

Premature ovarian insufficiency (POI) is a condition in which there is a decline in ovarian function in women who are younger than 40 years resulting in a hypo-oestrogenic state with elevated gonadotrophins and oligomenorrhoea/amenorrhoea. This leads to short term complications of menopausal symptoms and long-term effects on bone and cardiovascular health, cognition as well as the impact of reduced fertility and sexual function associated with this condition. It is managed by sex steroid replacement either with HRT or combined hormonal contraception until the age of natural menopause (51) and this can provide a beneficial role with both symptom control and minimising the long-term adverse effects associated with this condition. Women who undergo a menopause between 40 and 45 years are deemed to have an "early menopause". The limited data available for this group suggest that they also have an increased morbidity if not adequately treated with hormone therapy. As such, women who have an early menopause should be managed in a similar way to those with POI, with the recommendation that they should take HRT at least until the natural age of menopause. This is the same for induced menopause that is caused by medical or surgical treatment that impacts the ovaries. It is important to ensure early diagnosis and access to specialist care to help support and manage these patients to reduce the symptoms and risks of long-term complications. This review looks at the diagnosis, causes, short and long-term complications and management of POI, early and induced menopause.

17ß-Estradiol (E2) Upregulates the ERα/SIRT1/PGC-1α Signaling Pathway and Protects Mitochondrial Function to Prevent Bilateral Oophorectomy (OVX)-Induced Nonalcoholic Fatty Liver Disease (NAFLD).

Premature menopause is associated with an increased prevalence of nonalcoholic fatty liver disease (NAFLD). Menopausal hormone therapy (MHT) has been widely used in clinical practice and has the potential to protect mitochondrial function and alleviate NAFLD. After bilateral oophorectomy (OVX), female rats without 17ß-estradiol (E2) intervention developed NAFLD, whereas E2 supplementation was effective in preventing NAFLD in female rats. The altered pathways and cellular events from both comparison pairs, namely, the OVX vs. sham group and the OVX vs. E2 group, were assessed using transcriptomic analysis. KEGG pathways enriched by both transcriptomic and metabolomic analyses strongly suggest that oxidative phosphorylation is a vital pathway that changes during the development of NAFLD and remains unchanged when E2 is applied. Liver tissue from the OVX-induced NAFLD group exhibited increased lipid peroxidation, impaired mitochondria, and downregulated ERα/SIRT1/PGC-1α expression. An in vitro study indicated that the protective effect of E2 treatment on hepatic steatosis could be abolished when ERα or SIRT1 was selectively inhibited. This damage was accompanied by reduced mitochondrial complex activity and increased lipid peroxidation. The current research indicates that E2 upregulates the ERα/SIRT1/PGC-1α signaling pathway and protects mitochondrial function to prevent OVX-induced NAFLD.

Concurrent uterine surgery and uptake of hormone therapy in patients undergoing bilateral salpingo-oophorectomy for risk-reducing or therapeutic indications.

OBJECTIVE: This study aimed to analyze factors associated with concurrent uterine surgery in patients undergoing bilateral salpingo-oophorectomy (BSO) for risk reducing or therapeutic purposes. Additionally, trends in surgical choice and uptake of post-operative hormone therapy (HT) were examined. METHODS: A 10-year retrospective study was conducted on patients who underwent risk-reducing or therapeutic BSO at one institution. Multinomial regression analysis of patient and case characteristics was performed evaluating associations with surgery type (BSO, BSO and hysterectomy, or BSO and endometrial sampling). Trends in surgery type and uptake of HT post operatively are described. RESULTS: Among the study sample of 643 patients, 140 (22%) patients underwent therapeutic BSO for a history of hormone receptor (HR) positive breast cancer, while the remainder underwent risk-reducing BSO due to a pathogenic variant and/or family history. Pathogenic variants included BRCA1 (141, 40%) BRCA2 (173, 49%), and Lynch syndrome genes (15, 4%). Regression analysis revealed significant associations between concurrent hysterectomy and Black race (RR = 3.55, CI = 1.51-8.38, p = 0.004), history of HR positive breast cancer (RR = 1.88, CI = 1.03-3.42, p = 0.04), and surgeon (Surgeon 1, RR = 2.43, CI = 1.36-4.35, p = 0.003). Among eligible patients under age 51, 36% initiated HT. Over the study period, concurrent hysterectomy rates declined while endometrial sampling increased. CONCLUSIONS: Rates of hysterectomy declined over the study period and slightly more than one-third of eligible patients utilized post-operative HT. Further research on concurrent uterine surgery is needed to establish standardized treatment recommendations in the risk-reducing and therapeutic BSO population. Additionally, education regarding the benefits of postoperative HT in eligible patients is warranted.

Subjective cognitive changes following premenopausal risk-reducing bilateral salpingo-oophorectomy.

OBJECTIVE: Women at high risk of ovarian cancer are commonly advised to undergo risk-reducing bilateral salpingo-oophorectomy (BSO) prior to natural menopause. Cognitive symptoms during natural menopause transition are frequently reported; however, very few studies have examined cognitive changes following surgical menopause. To address this gap, we explored the cognitive experiences of women within 24 months post BSO. METHODS: This observational cross-sectional sub-study is part of a larger project, the Early Menopause and Cognition Study (EM-COG). We investigated perceived cognitive experiences in Australian women (n = 16) who underwent risk-reducing BSO using qualitative interviews. Thematic analysis was undertaken to identify key themes. RESULTS: Fifteen out of 16 participants (93.75%) reported changes to cognition within 24 months post BSO. The key cognitive symptoms reported were brain fog, memory and retrieval difficulties, slower processing speed as well as attention difficulties. Five participants (31.3%) experienced negative mood symptoms post BSO. CONCLUSION: Findings from this study suggest that women experience subjective cognitive changes within 24 months post BSO. This period could be a vulnerable time for women's cognitive health. While these findings need to be confirmed by a large prospective study, our research indicates that psychoeducation and awareness will be helpful in managing cognitive symptoms after surgical menopause.

WHAM-A Prospective Study of Weight and Body Composition After Risk-Reducing Bilateral Salpingo-oophorectomy.

CONTEXT: Body weight and composition may change over the natural menopause transition. Whether surgical menopause has similar effects, and the impact of hormone replacement therapy (HRT), are unknown. Understanding the metabolic effects of surgical menopause will inform clinical care. OBJECTIVE: To prospectively measure weight and body composition over 24 months following surgical menopause compared with a similar comparison group who retained their ovaries. METHODS: Prospective observational study of weight change from baseline to 24 months in 95 premenopausal women at elevated risk of ovarian cancer planning risk-reducing salpingo-oophorectomy (RRSO) and 99 comparators who retained their ovaries. Change in body composition from baseline to 24 months was also assessed by dual-energy x-ray absorptiometry in a subgroup of 54 women who underwent RRSO and 81 comparators who retained their ovaries. In the subgroup, weight, fat mass, lean mass, and abdominal fat measures were compared between groups. RESULTS: At 24 months both groups had gained weight (RRSO 2760 ± 4860 g vs comparators 1620 ± 4540 g) with no difference between groups (mean difference 730 g; 95% CI 920 g to 2380 g; P = .383). In the body composition subgroup, there was no difference in weight between groups at 24 months (mean difference 944 g; 95% CI -1120 g to 2614 g; P = .431). RRSO women may have gained slightly more abdominal visceral adipose tissue (mean difference 99.0 g; 95% CI 8.8 g to 189.2 g; P = .032) but there were no other differences in body composition. There were also no differences in weight or body composition between HRT users and nonusers at 24 months. CONCLUSION: 24 months after RRSO, there was no difference in body weight compared with women who retained their ovaries. RRSO women gained more abdominal visceral adipose tissue than comparators, but there were no other differences in body composition. Use of HRT following RRSO had no effect on these outcomes.

Comparison of plasma oxytocin level in women with natural and surgical menopause.

OBJECTIVE: We aimed to investigate plasma oxytocin level in women with natural and surgical menopause and its relation with other metabolic parameters. METHODS: This study included 89 postmenopausal women admitted to menopausal outpatient clinics and gave written consent to participate. Participants were allocated into natural (Group 1; n = 61) and surgical (Group 2; n = 28) menopause groups based on causative process for the onset of menopause. After the clinical evaluation and physical examination, blood samples are collected for biochemical profile and plasma oxytocin levels. The complete blood count, lipid profile, thyroid panel, blood glucose concentration, vitamin D and liver enzymes were measured by autoanalyzer, plasma oxytocin level was measured spectrophotometrically by ELISA method. RESULTS: The groups were comparable for age, body mass index, menopause duration, gravity and blood parameters measured except significantly different plasma oxytocin levels between the two groups as 6.8 (3.2-20.6) ng/ml in natural menopause group and 4.2 (2.9-18.2) ng/ml in surgical menopause group (p < 0.001). Plasma oxytocin level was also negatively correlated with age (r = -0.245, p = 0.022) and menopausal duration (r = -0.275, p = 0.01). CONCLUSION: Our results point out that oxytocin might be a target hormone to manage menopause associated disorders and/or it should be considered for its role in the differences in the incidences of postmenopausal diseases and quality of life in the course of natural and surgical menopausal transition.

Age at menopause and all-cause and cause-specific dementia: a prospective analysis of the UK Biobank cohort.

STUDY QUESTION: Are there associations between natural or surgical menopause and incident dementia by age at menopause? SUMMARY ANSWER: Compared to age at menopause of 46-50 years, earlier natural menopause (≤40 and 41-45 years) was related to higher risk of all-cause dementia, while a U-shape relationship was observed between age at surgical menopause and risk of dementia. WHAT IS KNOWN ALREADY: Menopause marks the end of female reproductive period. Age at menopause reflects the length of exposure to endogenous estrogen. Evidence on the association between age at natural, surgical menopause, and risk of dementia has been inconsistent. STUDY DESIGN, SIZE, DURATION: A population-based cohort study involving 160 080 women who participated in the UK Biobank study. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with no dementia at baseline, and had no missing data on key exposure variables and covariates were included. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs on the association of categorical menopause age with incident all-cause dementia, Alzheimer's disease (AD) and vascular dementia (VD). Restricted cubic splines were used to model the non-linear relationship between continuous age at natural, surgical menopause, and risk of dementia. In addition, we analyzed the interaction effect of ever-used menopausal hormone therapy (MHT) at baseline, income level, leisure activities, and age at menopause on risk of dementia. MAIN RESULTS AND THE ROLE OF CHANCE: Compared to women with age at menopause of 46-50 years, women with earlier natural menopause younger than 40 years (1.36, 1.01-1.83) and 41-45 years (1.19, 1.03-1.39) had a higher risk of all-cause dementia, while late natural menopause >55 years was linked to lower risk of dementia (0.83, 0.71-0.98). Compared to natural menopause, surgical menopause was associated with 10% higher risk of dementia (1.10, 0.98-1.24). A U-shape relationship was observed between surgical menopause and risk of dementia. Women with surgical menopause before age 40 years (1.94, 1.38-2.73) and after age 55 years (1.65, 1.21-2.24) were both linked to increased risk of all-cause dementia. Women with early natural menopause without ever taking MHT at baseline had an increased risk of AD. Also, in each categorized age at the menopause level, higher income level or higher number of leisure activities was linked to a lowers risk of dementia. LIMITATIONS, REASONS FOR CAUTION: Menopausal age was based on women's self-report, which might cause recall bias. WIDER IMPLICATION OF THE FINDINGS: Women who experienced natural menopause or had surgical menopause at an earlier age need close monitoring and engagement for preventive health measures to delay the development of dementia. STUDY FUNDING/COMPETING INTERESTS: This work was supported by the Start-up Foundation for Scientific Research in Shandong University (202099000066), Science Fund Program for Excellent Young Scholars of Shandong Provence (Overseas) (2022HWYQ-030), and the National Natural Science Foundation of China (82273702). There are no competing interests. TRIAL REGISTRATION NUMBER: N/A.

Care after premenopausal risk-reducing salpingo-oophorectomy in high-risk women: Scoping review and international consensus recommendations.

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease.

17ß-oestradiol inhibits ferroptosis in the hippocampus by upregulating DHODH and further improves memory decline after ovariectomy.

Ovariectomy (OVX) conducted before the onset of natural menopause is considered to bringing forward and accelerate the process of ageing-associated neurodegeneration. However, the mechanisms underlying memory decline and other cognitive dysfunctions following OVX are unclear. Given that iron accumulates during ageing and after OVX, we hypothesized that excess iron accumulation in the hippocampus would cause ferroptosis-induced increased neuronal degeneration and death associated with memory decline. In the current study, female rats that underwent OVX showed decreased dihydroorotate dehydrogenase (DHODH) expression and reduced performance in the Morris water maze (MWM). We used primary cultured hippocampal cells to explore the ferroptosis resistance-inducing effect of 17ß-oestradiol (E2). The data supported a vital role of DHODH in neuronal ferroptosis. Specifically, E2 alleviated ferroptosis induced by erastin and ferric ammonium citrate (FAC), which can be blocked by brequinar (BQR). Further in vitro studies showed that E2 reduced lipid peroxidation levels and improved the behavioural performance of OVX rats. Our research interprets OVX-related neurodegeneration with respect to ferroptosis, and both our in vivo and in vitro data show that E2 supplementation exerts beneficial antiferroptotic effects by upregulating DHODH. Our data demonstrate the utility of E2 supplementation after OVX and provide a potential target, DHODH, for which hormone therapy has not been available.

Counselling of path_BRCA carriers who are considering risk-reducing oophorectomy.

path_BRCA 1/2 increases a woman's lifetime risk of breast and ovarian cancer. Interventions can be offered which manage cancer risk; annual breast screening from age 30, chemoprevention and, once a woman's family is complete, risk-reducing surgery. The latter is the most effective method of reducing cancer in path_BRCA carriers; salpingo-oophorectomy reduces breast and ovarian cancer, respectively, by up to 50% and 95%. Factors affecting a woman's decision to undergo risk-reducing surgery are complex; dominant factors include risks of surgery, effect on cancer outcomes and menopausal sequelae. Specific information relating to hormone replacement and non-hormonal alternatives are an important consideration for women but, are often overlooked. Informative counselling is required to enable satisfaction with the chosen intervention whilst improving survival outcomes. This review paper outlines the current data pertaining to these decision-making factors and provides a proforma to enable effective counselling.

Real-world practice of estrogen therapy after surgery for endometrial cancer: a descriptive study using a Japanese claims database.

BACKGROUND: Estrogen therapy (ET) plays a key role in maintaining the post-surgical quality of life of patients with endometrial cancer. This study investigated the reality of the use of ET after endometrial cancer surgery in Japan. METHODS: Using a healthcare database in Japan, patients who underwent surgery for endometrial cancer between the ages of 40 and 59 years from January 2006 to March 2021 were included. The cumulative prescriptions of ET after endometrial cancer surgeries in patients who had received chemotherapy or radiation therapy (adj-group) and those who did not (non-adj-group) was estimated using the Kaplan-Meier method. RESULTS: Of the 1475 patients, 115 received ET, among whom transdermal estradiol was initiated in 100 (87.0%) individuals. The cumulative proportions of ET prescription 24 months after surgery [95% confidence intervals (CIs)] were 0.088 [0.072, 0.11] in the non-adj-group and 0.058 [0.040, 0.084] in the adj-group. The cumulative proportion [95% CI] of women who received ET at 24 months after surgeries decreased with increasing age, ranging from 0.29 [0.21, 0.38] in the 40‒44 years old to 0.009 [0.002, 0.034] in the 55‒59 years old women in the non-adj-group and from 0.17 [0.094, 0.31] in the 40‒44 years old to 0 in the 55‒59 years old women in the adj-group. CONCLUSION: The present study shows that ET after endometrial cancer surgery may be underused, even in women who underwent surgery between 40 and 44 years of age and without adjuvant therapy.

Behavioral Despair Is Blocked by the Flavonoid Chrysin (5,7-Dihydroxyflavone) in a Rat Model of Surgical Menopause.

Women have a high susceptibility to the negative effects of stress. Hormonal changes experienced throughout their reproductive life partially contribute to a higher incidence of anxiety and depression symptoms, particularly, during natural or surgical menopause. In preclinical research, the flavonoid chrysin (5,7-dihydroxyflavone) exerts anxiolytic- and anti-despair-like effects; however, it is unknown whether chrysin exerts a protective effect against the behavioral changes produced by acute stress on locomotor activity and behavioral despair in rats at 12-weeks post-ovariectomy. Ovariectomized female Wistar rats were assigned to eight groups: vehicle group (10% DMSO), three groups with chrysin and three groups with the same dose of allopregnanolone (0.5, 1, and 2 mg/kg), and one group with diazepam (2 mg/kg). The treatments were administered for seven consecutive days and the effects were evaluated in the locomotor activity and swimming tests. Chrysin (2 mg/kg) increased the latency to first immobility and decreased the total immobility time in the swimming test as the reference drugs allopregnanolone and diazepam (2 mg/kg); while locomotor activity prevented the behavioral changes produced by swimming. In conclusion, chrysin exerts a protective effect against the behavioral changes induced by acute stress, similarly to the neurosteroid allopregnanolone and the benzodiazepine diazepam in rats subjected to a surgical menopause model.

Sexual functioning more than 15 years after premenopausal risk-reducing salpingo-oophorectomy.

BACKGROUND: Women with a BRCA1/2 pathogenic variant are advised to undergo premenopausal risk-reducing salpingo-oophorectomy after completion of childbearing, to reduce their risk of ovarian cancer. Several studies reported less sexual pleasure 1 to 3 years after a premenopausal oophorectomy. However, the long-term effects of premenopausal oophorectomy on sexual functioning are unknown. OBJECTIVE: This study aimed to study long-term sexual functioning in women at increased familial risk of breast or ovarian cancer who underwent a risk-reducing salpingo-oophorectomy either before the age of 46 years (premenopausal group) or after the age of 54 years (postmenopausal group). Subgroup analyses were performed in the premenopausal group, comparing early (before the age of 41 years) and later (at ages 41-45 years) premenopausal risk-reducing salpingo-oophorectomy. STUDY DESIGN: Between 2018 and 2021, 817 women with a high familial risk of breast or ovarian cancer from an ongoing cohort study were invited to participate in our study. Because of a large difference in age in the study between the premenopausal and postmenopausal salpingo-oophorectomy groups, we restricted the comparison of sexual functioning between the groups to 368 women who were 60 to 70 years old at completion of the questionnaire (226 in the premenopausal group and 142 in the postmenopausal group). In 496 women with a premenopausal risk-reducing salpingo-oophorectomy, we compared the sexual functioning between women in the early premenopausal group (n=151) and women in the later premenopausal group (n=345). Differences between groups were analyzed using multiple regression analyses, adjusting for current age, breast cancer history, use of hormone replacement therapy, body mass index, chronic medication use (yes or no), and body image. RESULTS: Mean times since risk-reducing salpingo-oophorectomy were 20.6 years in the premenopausal group and 10.6 years in the postmenopausal group (P<.001). The mean age at questionnaire completion was 62.7 years in the premenopausal group, compared with 67.0 years in the postmenopausal group (P<.001). Compared with 48.9% of women in the postmenopausal group, 47.4% of women in the premenopausal group were still sexually active (P=.80). Current sexual pleasure scores were the same for women in the premenopausal group and women in the postmenopausal group (mean pleasure score, 8.6; P=.99). However, women in the premenopausal group more often reported substantial discomfort than women in the postmenopausal group (35.6% vs 20.9%; P=.04). After adjusting for confounders, premenopausal risk-reducing salpingo-oophorectomy was associated with substantially more discomfort during sexual intercourse than postmenopausal risk-reducing salpingo-oophorectomy (odds ratio, 3.1; 95% confidence interval, 1.04-9.4). Moreover, after premenopausal risk-reducing salpingo-oophorectomy, more severe complaints of vaginal dryness were observed (odds ratio, 2.6; 95% confidence interval, 1.4-4.7). Women with a risk-reducing salpingo-oophorectomy before the age of 41 years reported similar pleasure and discomfort scores as women with a risk-reducing salpingo-oophorectomy between ages 41 and 45 years. CONCLUSION: More than 15 years after premenopausal risk-reducing salpingo-oophorectomy, the proportion of sexually active women was comparable with the proportion of sexually active women with a postmenopausal risk-reducing salpingo-oophorectomy. However, after a premenopausal risk-reducing salpingo-oophorectomy, women experienced more vaginal dryness and more often had substantial sexual discomfort during sexual intercourse. This did not lead to less pleasure with sexual activity.

Hormone replacement in premenopausal women treated with bilateral oophorectomy for ovarian cancer - a nationwide population-based study.

OBJECTIVE: To study the extent of hormone replacement therapy (HRT) dispensing in premenopausal women after being treated with bilateral salpingo-oophorectomy (BSOE) for ovarian cancer (OC). METHODS: Nationwide population- and register-based cohort study including women 18-50 years old, registered in The Swedish Quality Register for Gynecological Cancer (SQRGC), where BSOE was performed due to epithelial (EOC) and non-epithelial ovarian cancers (NEOC) or borderline ovarian tumor (BOT) between 2008 and 2014. Data on HRT dispensing was obtained from the National Prescribed Drug Register analyzed at semi-annual intervals from surgery until end of follow-up December 2015, including a logistic regression analysis. RESULTS: A cohort of 664 women were identified with OC, whereas 396 women had an EOC, 61 a NEOC and 207 a BOT. At surgery 49% of the women were ≤44 years. HRT dispensed to the total cohort varied between 32% and 41% the first five years after surgery. During follow-up at first 0.5-1 year 51% of the women <40 years were dispensed HRT compared to 25% of women ≥40 years. Of women with EOC, 21% dispensed HRT at first 0.5-1 year. In the multivariable regression analysis; age <40 (OR6.17, p < 0.001) and age 40-44 (OR2.95, p < 0.001) as well as BOT histology (OR3.84, p < 0.001) were found significant variables for dispensing of HRT. CONCLUSION: A majority of premenopausal women undergoing BSOE for OC did not use HRT postoperatively. Our study shows that there is a need to address HRT use after OC treatment in young women to prevent from morbidity and a poorer quality of life.
