Influence of prophylactic oophorectomy on mood and sexual function in women of menopausal transition or postmenopausal period

The efficacy of oral Lavandula angustifolia Mill. essential oil on menopausal symptoms, serum lipid profile, and cortisol concentration in postmenopausal women: A triple-blind, randomized, controlled trial

OBJECTIVE

To determine the effect of oral Lavandula angustifolia Mill. essential oil (LEO) on menopausal symptoms, serum cortisol level, and lipid profile in postmenopausal women.

METHODS

This was a triple-blind parallel-armed randomized trial. Seventy-two postmenopausal women aged 50-65 years referring to healthcare centers in Tabriz, Iran with a score of 15-42 on the Green scale were included from May 10, 2022 to May 22, 2023. The participants were randomly assigned to two groups with a 1:1 ratio and using four and six blocks. One group received LEO soft gel 80 mg per day, and another group received a similar placebo for 60 days. A demographic questionnaire and a Greene menopause symptom scale were used for data collection. The lipid profile (total cholesterol, triglyceride, LDL, HDL) and the serum levels of cortisol were measured using biochemical methods. Chi-square, Fisher's exact tests, Independent samples t-test, Analysis of Covariance (ANCOVA), Repeated measure ANOVA, and Paired sample t-test were utilized for analyses. A p-value less than 0.05 was considered statistically significant.

RESULTS

The demographic and personal characteristics of the participants were similar. After two months of intervention, all symptoms in psychological, physical, vasomotor, anxiety, depression, and sexual dysfunction domains were significantly relieved (decreased) among both groups (p < 0.003), except for sexual dysfunction, the reduction of which was not significant in the placebo group (p = 0.317). The mean (SD) total score of menopausal symptoms reduced from 27.4 (6.3) at baseline to 17.7 (4.9) at the end of the study in the LEO group (p < 0.001). It also decreased from 27.4 (7.1) to 17.6 (5.1) in the placebo group (p < 0.001). However, between-group analyses revealed that this reduction was significantly greater in the LEO group compared to the placebo group only in the sexual dysfunction (Mean (SD): 1.3 (0.6) vs. 1.0 (0.5); adjusted mean difference (95% confidence interval); p: - 0.35 (-0.67 to -0.02); 0.039). No significant within-group changes or between-group differences were observed (p > 0.05) in terms of studied serum markers.

CONCLUSION

The oral LEO exhibited a significant enhancement in sexual dysfunction among postmenopausal women. Therefore, it can be used alongside other therapies to improve sexual dysfunction during menopause. LEO did not affect lipid profile and serum cortisol level in this study.

Promoting good mental health over the menopause transition

The potential risk for mental health conditions over the menopause transition shapes women's expectations and informs putative physiological mechanisms regulating women's mental health. We review evidence from prospective studies reporting on associations between mental health conditions and the menopause transition. Major depressive disorder and the more prevalent subthreshold depressive symptoms are the most common conditions studied. We reviewed 12 prospective studies reporting depressive symptoms, major depressive disorder, or both over the menopause transition and found no compelling evidence for a universal increased risk for either condition. However, specific subgroups of participants, primarily defined by menopause-related risk factors (ie, vasomotor symptoms that are severe or disturb sleep, a long duration of the transition, or reproductive hormone dynamics) and psychosocial risk factors (eg, stressful life events), were vulnerable to depressive symptoms. The increased risk of major depressive disorder over the menopause transition appears predominantly in individuals with previous major depressive disorder. Greater focus on recognising risk factors in primary care is warranted. On the basis of scarce data, we found no compelling evidence that risk of anxiety, bipolar disorder, or psychosis is universally elevated over the menopause transition. Potential misattribution of psychological distress and psychiatric disorders to menopause could harm women by delaying accurate diagnosis and the initiation of effective psychotropic treatments, and by creating negative expectations for people approaching menopause. A paradigm shift is needed. We conclude with recommendations for the detection and treatment of depressive symptoms or major depressive disorder and strategies to promote good mental health over the menopause transition, while responsibly preparing and supporting those at risk.

Psychosocial predictors of change in sexual activity and sexual function after hysterectomy in women with pelvic pain

BACKGROUND

Potential impact on sexual function is an often-cited concern for many patients considering hysterectomy. The existing literature indicates that sexual function remains stable to slightly improved for most patients who undergo hysterectomy, but most studies demonstrate a small subset of patients in whom sexual function declines after surgery. Unfortunately, there is a lack of clarity as to surgical, clinical, and psychosocial factors that may influence the likelihood of sexual activity after surgery or the magnitude and direction of change in sexual function. Although psychosocial factors are strongly associated with overall female sexual function, there is minimal data exploring the potential impact of these factors on the change in sexual function after hysterectomy.

OBJECTIVE

This study aimed to evaluate the relationship between baseline psychosocial factors and both sexual activity and sexual function at 6 months after hysterectomy.

STUDY DESIGN

Patients undergoing hysterectomy for benign, non-obstetric indications were prospectively recruited as part of an observational cohort study evaluating presurgical predictors of posthysterectomy outcomes on pain, quality of life, and sexual function. The Female Sexual Function Index was administered before hysterectomy and 6 months after surgery. Presurgical psychosocial assessments included validated self-reported measures of depression, resilience, relationship satisfaction, emotional support, and social participation.

RESULTS

Complete data was available for 193 patients, of whom 149 (77.2%) reported sexual activity at 6 months after hysterectomy. In the binary logistic regression model examining sexual activity at 6 months, older age was associated with a lower likelihood of sexual activity (odds ratio, 0.91; 95% confidence interval, 0.85-0.96; P=.002). Higher relationship satisfaction before surgery was associated with a greater likelihood of sexual activity at 6 months (odds ratio, 1.09; 95% confidence interval, 1.02-1.16; P=.008). As expected, preoperative sexual activity was associated with a greater likelihood of postoperative sexual activity (odds ratio, 9.78; 95% confidence interval, 3.95-24.19, P<.001). Analyses using Female Sexual Function Index scores were limited to patients who were sexually active at both time points (n=132 [68.4%]). The total Female Sexual Function Index score did not change significantly from baseline to 6 months, but there were statistically significant changes in several individual domains of sexual function. Patients reported significant improvement in desire (P=.012), arousal (P=.023), and pain (P<.001) domains. However, significant decreases were reported in orgasm (P<.001) and satisfaction (P<.001) domains. The proportion of patients who met the criteria for sexual dysfunction was quite high (>60%) at both time points, but there was not a statistically significant change in the proportion from baseline to 6 months. In the multivariate linear regression model, there was no relationship between change in sexual function score and any of the variables examined, including age, endometriosis history, pelvic pain severity, or psychosocial measures.

CONCLUSION

In this cohort of patients with pelvic pain undergoing hysterectomy for benign indications, both sexual activity and sexual function remained fairly stable after hysterectomy. Higher relationship satisfaction, younger age, and preoperative sexual activity were associated with a greater probability of sexual activity at 6 months after surgery. Psychosocial factors, such as depression, relationship satisfaction, and emotional support, and history of endometriosis were not related to change in sexual function among patients who were sexually active both before hysterectomy and at 6 months after surgery.

Sexual Function and Mood Disorders Among Menopausal Women: A Systematic Scoping Review

BACKGROUND

Changes in sex hormones during menopause may have detrimental effects on a woman's sexual function and cause mood disorders. The treatment of both conditions is a challenge in gynecology.

AIM

To review the published literature on sexual function and mood disorders among peri- and postmenopausal women.

METHODS

The review is based on the methodological framework of scoping reviews. We searched electronic databases including Medline (PubMed), Scopus, Embase, and Web of Science (WoS). Publications that reported data about the relationship between sexual function and mood disorders among menopausal women were included in the review. The search was not subject to any limitation in terms of time or method.

OUTCOMES

The main outcome measures used for the review were sexual dysfunction and mood disorders.

RESULTS

We found 106 total records. After a full-text screening we included 19 studies from 1986 to 2020 based on various methodologies; the majority of the studies16 were cross-sectional. Investigations that addressed the symptoms of mood disorders and some domains of sexual function showed a close relationship between sexual dysfunction and mood disorders among menopausal women.

CLINICAL IMPLICATIONS

In clinical practice, it would be appropriate to screen women for at least one mood disorder or sexual dysfunction. If a woman suffers from either, it will be necessary to assess for a further disorder as well.

STRENGTHS & LIMITATIONS

The review was based on a detailed search of the published literature concerning mood disorders and sexual dysfunction among menopausal women compared to women of reproductive age. Despite the clinical importance of the subject, the number of studies eligible for inclusion in the review are rather small. Further investigation of the topic is clearly warranted.

CONCLUSIONS

While the association between sexual dysfunction and mood disorders appears to be bidirectional, future studies will have to investigate the specific mechanisms by which sexual dysfunction could lead to mood disorders (or vice versa). Future studies should specifically address sexual dysfunctions and attitudes of partners, BMI, family support, sleep, and multiparity.

Quality of life and sexual function after abdominal versus laparoscopic hysterectomy: a prospective study

BACKGROUND

This study aimed to evaluate the quality of life (QoL) and sexual function of women who underwent total abdominal hysterectomy and total laparoscopic hysterectomy.

METHODS

In this prospective cohort study, a total of 121 patients who underwent total abdominal hysterectomy (N.=65) and total laparoscopic hysterectomy (N.=56) operations for benign indications were included. Sociodemographic features, obstetric histories, and clinical characteristics of the patients were noted. Quality of life assessment was conducted with the World Health Organization Quality of Life-BREF questionnaire, which has five domains: overall quality of life + health, physical health, psychological health, social relationships, and environment. Sexual function was assessed by the Golombok-Rust Inventory of Sexual Satisfaction Scale with subscales of infrequency, non-communication, avoidance, non-sensuality, dissatisfaction, vaginismus, and anorgasmia. The patients were asked to fill in both questionnaires before the operation and six months after the operation.

RESULTS

Of the 121 patients, 104 of them completed the postoperative surveys. In the total laparoscopic hysterectomy group, the individual improvements of the overall quality of life + health physical, and psychological health domains were statistically higher than the total abdominal hysterectomy group. In terms of sexual function, the total abdominal hysterectomy group had worse avoidance, non-sensuality, dissatisfaction, and vaginismus subscale scores and total score both in the preoperative and postoperative period compared to the total laparoscopic hysterectomy group. However, the individual differences and the number of patients exhibiting sexual dysfunction before and after surgery were not statistically significant in both groups.

CONCLUSIONS

Laparoscopic hysterectomy was superior to abdominal hysterectomy in improving the quality of life of the patients. Both abdominal and laparoscopic hysterectomies were not found to affect female sexuality.

Ovarian cancer incidence and death in average-risk women undergoing bilateral salpingo-oophorectomy at benign hysterectomy

BACKGROUND

Opportunistic bilateral salpingo-oophorectomy is often offered to patients undergoing benign hysterectomy to prevent ovarian cancer, but the magnitude of risk reduction obtained with bilateral salpingo-oophorectomy in this population remains unclear and must be weighed against potential risks of ovarian hormone deficiency.

OBJECTIVE

This study aimed to quantify the relative and absolute risk reduction in ovarian cancer incidence and death associated with bilateral salpingo-oophorectomy at the time of benign hysterectomy.

STUDY DESIGN

We performed a population-based cohort study of all adult women (≥20 years) undergoing benign hysterectomy from 1996 to 2010 in Ontario, Canada. Patients with ovarian pathology, previous breast or gynecologic cancer, or evidence of genetic susceptibility to malignancy were excluded. Inverse probability of treatment-weighted Fine-Gray subdistribution hazard models were used to quantify the effect of bilateral salpingo-oophorectomy on ovarian cancer incidence and death while accounting for competing risks and adjusting for demographic characteristics, gynecologic conditions, and comorbidities. Analyses were performed in all women and specifically in women of postmenopausal age (≥50 years) at the time of hysterectomy.

RESULTS

We identified 195,282 patients (bilateral salpingo-oophorectomy, 24%; ovarian conservation, 76%) with a median age of 45 years (interquartile range, 40-51 years). Over a median follow-up of 16 years (interquartile range, 12-20 years), 548 patients developed ovarian cancer (0.3%), and 16,170 patients (8.3%) died from any cause. Bilateral salpingo-oophorectomy was associated with decreased ovarian cancer incidence (hazard ratio, 0.23; 95% confidence interval, 0.14-0.38; P<.001) and decreased ovarian cancer death (hazard ratio, 0.30; 95% confidence interval, 0.16-0.57; P<.001). At 20 years follow-up, the weighted cumulative incidences of ovarian cancer were 0.08% and 0.46% with bilateral salpingo-oophorectomy and ovarian conservation, respectively, yielding an absolute risk reduction of 0.38% (95% confidence interval, 0.32-0.45; number needed to treat, 260). After restricting to women aged ≥50 years at hysterectomy, the absolute risk reduction was 0.62% (95% confidence interval, 0.47-0.77; number needed to treat, 161).

CONCLUSION

Bilateral salpingo-oophorectomy resulted in a significant absolute reduction in ovarian cancer among women undergoing benign hysterectomy. Population-average risk estimates derived in this study should be balanced against other potential implications of bilateral salpingo-oophorectomy to inform practice guidelines, patient decision-making, and surgical management.

Estrogen receptors and the aging brain

The female sex hormone estrogen has been ascribed potent neuroprotective properties. It signals by binding and activating estrogen receptors that, depending on receptor subtype and upstream or downstream effectors, can mediate gene transcription and rapid non-genomic actions. In this way, estrogen receptors in the brain participate in modulating neural differentiation, proliferation, neuroinflammation, cholesterol metabolism, synaptic plasticity, and behavior. Circulating sex hormones decrease in the course of aging, more rapidly at menopause in women, and slower in men. This review will discuss what this drop entails in terms of modulating neuroprotection and resilience in the aging brain downstream of spatiotemporal estrogen receptor alpha (ERα) and beta (ERβ) signaling, as well as in terms of the sex differences observed in Alzheimer's disease (AD) and Parkinson's disease (PD). In addition, controversies related to ER expression in the brain will be discussed. Understanding the spatiotemporal signaling of sex hormones in the brain can lead to more personalized prevention strategies or therapies combating neurodegenerative diseases.

Association of bilateral salpingo-oophorectomy with all cause and cause specific mortality: population based cohort study

OBJECTIVES

To determine if bilateral salpingo-oophorectomy, compared with ovarian conservation, is associated with all cause or cause specific death in women undergoing hysterectomy for non-malignant disease, and to determine how this association varies with age at surgery.

DESIGN

Population based cohort study.

SETTING

Ontario, Canada from 1 January 1996 to 31 December 2015, and follow-up to 31 December 2017.

PARTICIPANTS

200 549 women (aged 30-70 years) undergoing non-malignant hysterectomy, stratified into premenopausal (<45 years), menopausal transition (45-49 years), early menopausal (50-54 years), and late menopausal (≥55 years) groups according to age at surgery; median follow-up was 12 years (interquartile range 7-17).

EXPOSURES

Bilateral salpingo-oophorectomy versus ovarian conservation.

MAIN OUTCOMES MEASURES

The primary outcome was all cause death. Secondary outcomes were non-cancer and cancer death. Within each age group, overlap propensity score weighted survival models were used to examine the association between bilateral salpingo-oophorectomy and mortality outcomes, while adjusting for demographic characteristics, gynaecological conditions, and comorbidities. To account for comparisons in four age groups, P<0.0125 was considered statistically significant.

RESULTS

Bilateral salpingo-oophorectomy was performed in 19%, 41%, 69%, and 81% of women aged <45, 45-49, 50-54, and ≥55 years, respectively. The procedure was associated with increased rates of all cause death in women aged <45 years (hazard ratio 1.31, 95% confidence interval 1.18 to 1.45, P<0.001; number needed to harm 71 at 20 years) and 45-49 years (1.16, 1.04 to 1.30, P=0.007; 152 at 20 years), but not in women aged 50-54 years (0.83, 0.72 to 0.97, P=0.018) or ≥55 years (0.92, 0.82 to 1.03, P=0.16). Findings in women aged <50 years were driven largely by increased non-cancer death. In secondary analyses identifying a possible change in the association between bilateral salpingo-oophorectomy and all cause death with advancing age at surgery, the hazard ratio gradually decreased during the menopausal transition and remained around 1 at all ages thereafter.

CONCLUSION

In this observational study, bilateral salpingo-oophorectomy at non-malignant hysterectomy appeared to be associated with increased all cause mortality in women aged <50 years, but not in those aged ≥50 years. While caution is warranted when considering bilateral salpingo-oophorectomy in premenopausal women without indication, this strategy for ovarian cancer risk reduction does not appear to be detrimental to survival in postmenopausal women.

Endometriosis and cancer: a systematic review and meta-analysis

BACKGROUND

Endometriosis is an often chronic, inflammatory gynaecologic condition affecting 190 million women worldwide. Studies have reported an elevated cancer risk among patients with endometriosis. However, prior research has included methodologic issues that impede valid and robust interpretation.

OBJECTIVE AND RATIONALE

We conducted a meta-analysis of studies investigating the association between endometriosis and cancer risk and analysed the results by methodologic characteristics. We discuss the implications of cancer screening in patients and management challenges faced by clinicians.

SEARCH METHODS

We searched PubMed and Embase databases for eligible studies from inception through 24 October 2019. We included cohort and case-control studies examining the association between endometriosis and cancer risk; cross-sectional studies and case reports were excluded. Publications had to present risk/rate/odds estimates with 95% CI. Random effects meta-analysis was used to estimate summary relative risks (SRR) and CIs. Heterogeneity across studies was assessed by the Q test and I2 statistics, and publication bias using Egger's and Begg's tests. Risk of bias and quality of the included studies were assessed using the risk of bias in non-randomized studies of interventions (ROBINS-I) tool.

OUTCOMES

Forty-nine population-based case-control and cohort studies were included. Twenty-six studies were scored as having a 'serious'/'critical' risk of bias, and the remaining 23 'low'/'moderate'. Cancer-specific analyses showed a positive association between endometriosis and ovarian cancer risk (SRR = 1.93, 95% CI = 1.68-2.22; n = 24 studies) that was strongest for clear cell (SRR = 3.44, 95% CI = 2.82-4.42; n = 5 studies) and endometrioid (SRR = 2.33, 95% CI = 1.82-2.98; n = 5 studies) histotypes (Pheterogeneity < 0.0001), although with significant evidence of both heterogeneity across studies and publication bias (Egger's and Begg's P-values < 0.01). A robust association was observed between endometriosis and thyroid cancer (SRR = 1.39, 95% CI =1.24-1.57; n = 5 studies), a very small association with breast cancer (SRR = 1.04, 95% CI =1.00-1.09; n = 20 studies) and no association with colorectal cancer (SRR = 1.00, 95% CI =0.87-1.16; n = 5 studies). The association with endometrial cancer was not statistically significant (SRR = 1.23, 95% CI =0.97-1.57; n = 17 studies) overall and wholly null when restricted to prospective cohort studies (SRR = 0.99, 95% CI =0.72-1.37; n = 5 studies). The association with cutaneous melanoma was also non-significant (SRR = 1.17, 95% CI =0.97-1.41; n = 7 studies) but increased in magnitude and was statistically significant when restricted to studies with low/moderate risk of bias (SRR = 1.71, 95% CI = 1.24-2.36, n = 2 studies). The most robust finding both in terms of statistical significance and magnitude of effect was an inverse association with cervical cancer (SRR = 0.68, 95% CI =0.56-0.82; n = 4 studies); however, this result has a high potential to reflect heightened access to detection of dysplasia for women who reached an endometriosis diagnosis and is thus likely not causal. Several additional cancer types were explored based on <4 studies.

WIDER IMPLICATIONS

Endometriosis was associated with a higher risk of ovarian and thyroid, and minimally (only 4% greater risk) with breast cancer, and with a lower risk of cervical cancer. However, this meta-analysis confirms that: a majority of studies had severe/critical risk of bias; there is impactful heterogeneity across studies-and for ovarian cancer, publication bias; and causal inference requires temporality, which in many studies was not considered. We discuss the implications of these potential associations from the perspectives of patients with endometriosis, clinicians involved in their care, and scientists investigating their long-term health risks.

Mindfulness-based stress reduction for menopausal symptoms after risk-reducing salpingo-oophorectomy (PURSUE study): a randomised controlled trial

OBJECTIVE

To assess the short- and long-term effects of mindfulness-based stress reduction (MBSR) on the resulting quality of life, sexual functioning, and sexual distress after risk-reducing salpingo-oophorectomy (RRSO).

DESIGN

Randomised controlled trial.

SETTING

A specialised family cancer clinic of the university medical center Groningen.

POPULATION

Sixty-six women carriers of the BRCA1/2 mutation who developed at least two moderate-to-severe menopausal symptoms after RRSO.

METHODS

Women were randomised to an 8-week MBSR training programme or to care as usual (CAU).

MAIN OUTCOME MEASURES

Change in the Menopause-Specific Quality of Life Questionnaire (MENQOL), the Female Sexual Function Index, and the Female Sexual Distress Scale, administered from baseline at 3, 6, and 12 months. Linear mixed modelling was applied to compare the effect of MBSR with CAU over time.

RESULTS

At 3 and 12 months, there were statistically significant improvements in the MENQOL for the MBSR group compared with the CAU group (both P = 0.04). At 3 months, the mean MENQOL scores were 3.5 (95% confidence interval, 95% CI 3.0-3.9) and 3.8 (95% CI 3.3-4.2) for the MBSR and CAU groups, respectively; at 12 months, the corresponding values were 3.6 (95% CI 3.1-4.0) and 3.9 (95% CI 3.5-4.4). No significant differences were found between the MBSR and CAU groups in the other scores.

CONCLUSION

Mindfulness-based stress reduction was effective at improving quality of life in the short- and long-term for patients with menopausal symptoms after RRSO; however, it was not associated with an improvement in sexual functioning or distress.

TWEETABLE ABSTRACT

Mindfulness improves menopause-related quality of life in women after risk-reducing salpingo-oophorectomy.

Mindfulness, cognitive behavioural and behaviour-based therapy for natural and treatment-induced menopausal symptoms: a systematic review and meta-analysis

Background

During menopause women experience vasomotor and psychosexual symptoms that cannot entirely be alleviated with hormone replacement therapy (HRT). Besides, HRT is contraindicated after breast cancer.

Objectives

To review the evidence on the effectiveness of psychological interventions in reducing symptoms associated with menopause in natural or treatment‐induced menopausal women.

Search strategy

Medline/Pubmed, PsycINFO, EMBASE and AMED were searched until June 2017.

Selection criteria

Randomised controlled trials (RCTs) concerning natural or treatment‐induced menopause, investigating mindfulness or (cognitive‐)behaviour‐based therapy were selected. Main outcomes were frequency of hot flushes, hot flush bother experienced, other menopausal symptoms and sexual functioning.

Data collection and analysis

Study selection and data extraction were performed by two independent researchers. A meta‐analysis was performed to calculate the standardised mean difference (SMD).

Main results

Twelve RCTs were included. Short‐term (<20 weeks) effects of psychological interventions in comparison to no treatment or control were observed for hot flush bother (SMD −0.54, 95% CI −0.74 to −0.35, P < 0.001, I² = 18%) and menopausal symptoms (SMD −0.34, 95% CI −0.52 to −0.15, P < 0.001, I² = 0%). Medium‐term (≥20 weeks) effects were observed for hot flush bother (SMD −0.38, 95% CI −0.58 to −0.18, P < 0.001, I² = 16%). [Correction added on 9 July 2018, after first online publication: there were miscalculations of the mean end point scores for hot flush bother and these have been corrected in the preceding two sentences.] In the subgroup treatment‐induced menopause, consisting of exclusively breast cancer populations, as well as in the subgroup natural menopause, hot flush bother was reduced by psychological interventions. Too few studies reported on sexual functioning to perform a meta‐analysis.

Conclusions

Psychological interventions reduced hot flush bother in the short and medium‐term and menopausal symptoms in the short‐term. These results are especially relevant for breast cancer survivors in whom HRT is contraindicated. There was a lack of studies reporting on the influence on sexual functioning.

Ovarian conservation vs removal at the time of benign hysterectomy

Over the last 2 decades, the rate of oophorectomy at the time of hysterectomy in the United States has consistently been between 40-50%. A decline in hormone use has been observed since the release of the principal results of the Women's Health Initiative. Oophorectomy appears to be associated with an increased risk of coronary heart disease, as well as deleterious effects on overall mortality, cognitive functioning, and sexual functioning. Estrogen deficiency from surgical menopause is associated with bone mineral density loss and increased fracture risk. While hormone therapy may mitigate these effects, at no age does there appear to be a survival benefit associated with oophorectomy. Reduction of ovarian cancer risk may be accomplished with salpingectomy at the time of hysterectomy.

Salpingo-oophorectomy at the Time of Benign Hysterectomy: A Systematic Review

OBJECTIVE

To compare the long-term risks associated with salpingo-oophorectomy with ovarian conservation at the time of benign hysterectomy.

DATA SOURCES

MEDLINE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials were searched from inception to January 30, 2015. We included prospective and retrospective comparative studies of women with benign hysterectomy who had either bilateral salpingo-oophorectomy (BSO) or conservation of one or both ovaries.

METHODS OF STUDY SELECTION

Reviewers double-screened 5,568 citations and extracted eligible studies into customized forms. Twenty-six comparative studies met inclusion criteria. Studies were assessed for results, quality, and strength of evidence.

TABULATION, INTEGRATION, AND RESULTS

Studies were extracted for participant, intervention, comparator, and outcomes data. When compared with hysterectomy with BSO, prevalence of reoperation and ovarian cancer was higher in women with ovarian conservation (ovarian cancer risk of 0.14-0.7% compared with 0.02-0.04% among those with BSO). Hysterectomy with BSO was associated with a lower incidence of breast and total cancer, but no difference in the incidence of cancer mortality was found when compared with ovarian conservation. All-cause mortality was higher in women younger than age 45 years at the time of BSO who were not treated with estrogen replacement therapy (hazard ratio [HR] 1.41, 95% confidence interval [CI] 1.04-1.92). Coronary heart disease (HR 1.26, 95% CI 1.04-1.54) and cardiovascular death were higher among women with BSO (HR 1.84, 95% CI 1.27-2.68), especially women younger than 45 years who were not treated with estrogen. Finally, there was an increase in the prevalence of dementia and Parkinson disease among women with BSO compared with conservation, especially in women younger than age 50 years. Clinical practice guidelines were devised based on these results.

CONCLUSION

Bilateral salpingo-oophorectomy offers the advantage of effectively eliminating the risk of ovarian cancer and reoperation but can be detrimental to other aspects of health, especially among women younger than age 45 years.

Ovarian Sex Hormones Modulate Compulsive, Affective and Cognitive Functions in A Non-Induced Mouse Model of Obsessive-Compulsive Disorder

There is currently a lack of understanding of how surgical menopause can influence obsessions, compulsions and associated affective and cognitive functions in female obsessive-compulsive disorder (OCD) patients. Early menopause in women due to surgical removal of ovaries not only causes dramatic hormonal changes, but also may induce affective and cognitive disorders. Here, we tested if surgical removal of ovaries (ovariectomy, OVX), which mimics surgical menopause in humans, would result in exacerbation of compulsive, affective and cognitive behaviors in mice strains that exhibit a spontaneous compulsive-like phenotype. Female mice from compulsive-like BIG, non-compulsive SMALL and randomly-bred Control strains were subjected to OVX or sham-surgery. After 7 days animals were tested for nest building and marble burying to measure compulsive-like behavior. The elevated plus maze and open field tests measured anxiety-like behaviors, while memory was assessed by the novel object recognition. Acute OVX resulted in exacerbation of compulsive-like and anxiety-like behaviors in compulsive-like BIG mice. No significant effects of OVX were observed for the non-compulsive SMALL and Control strains. Object recognition memory was impaired in compulsive-like BIG female mice compared to the Control mice, without an effect of OVX on the BIG mice. We also tested whether 17 β-estradiol (E2) or progesterone (P4) could reverse the effects of OVX. E2, but not P4, attenuated the compulsive-like behaviors in compulsive-like BIG OVX female mice. The actions of the sex steroids on anxiety-like behaviors in OVX females were strain and behavioral test dependent. Altogether, our results indicate that already existing compulsions can be worsened during acute ovarian deprivation concomitant with exacerbation of affective behaviors and responses to hormonal intervention in OVX female mice can be influenced by genetic background.

Object recognition memory deficit and depressive-like behavior caused by chronic ovariectomy can be transitorialy recovered by the acute activation of hippocampal estrogen receptors

It is well known that estradiol (E2) replacement therapy is effective on restoring memory deficits and mood disorders that may occur during natural menopause or after surgical ovarian removal (ovariectomy, OVX). However, it is still unknown the effectiveness of acute and localized E2 administration on the effects of chronic OVX. Here we tested the hypothesis that the intra-hippocampal E2 infusion, as well as specific agonists of estrogen receptors (ERs) alpha (ERα) and beta (ERβ), are able to mend novel object recognition (NOR) memory deficit and depressive-like behavior caused by 12 weeks of OVX. We found that both ERα and ERβ activation, at earlier stages of consolidation, recovered the NOR memory deficit caused by 12 w of OVX. Conversely, only the ERβ activation was effective in decreasing the depressive-like behavior caused by 12 w of OVX. Furthermore, we investigated the effect of OVX on hippocampal volume and ERs expression. The structural MRI showed no alteration in the hippocampus volume of 12 w OVX animals. Interestingly, ERα expression in the hippocampus decreased after one week of OVX, but increased in 12 w OVX animals. Overall, we may conclude that the chronic estrogen deprivation, induced by 12 weeks of OVX, modulates the hippocampal ERα expression and induces NOR memory deficit and depressive-like behaviors. Nonetheless, it is noteworthy that the acute effects of E2 on NOR memory and depressive-like behavior are still apparent even after 12 weeks of OVX.

Memory impairment is the most commonly reported cognitive symptom associated with major depressive disorder. Decreased hippocampal volume and neurogenesis in depression link hippocampal dysfunction with deficits in memory. Stress decreases hippocampal dendritic spine density and long-term potentiation (LTP) at glutamate synapses, a cellular correlate of learning and memory. However, elevated plasma levels of 17β estradiol (E2) during proestrus increase hippocampal structure and function, directly opposing the negative consequences of stress. In women, significant fluctuations in ovarian hormones likely increase vulnerability of hippocampal circuits to stress, potentially contributing to the greater incidence of depression compared to men. Using the learned helplessness model of depression and ovariectomized female rats, we investigated whether acquisition of helplessness and hippocampal synaptic dysfunction is differentially impacted by the presence or absence of plasma E2. We find that inescapable shock induces a greater incidence of helplessness in vehicle- versus E2-treated OVX rats. In the vehicle-treated group, LTP was absent at CA3-CA1 synapses in slices only from helpless rats, and CA1 spine density was decreased compared to resilient rats. In contrast, significant LTP was observed in slices from E2-treated helpless rats; importantly, spine density was not different between E2-treated helpless and resilient rats, dissociating spine density from the LTP magnitude. We also find that E2 replacement can reverse previously established helpless behavior. Thus, our results show that E2 replacement in OVX rats increases resilience and improves hippocampal plasticity, suggesting that E2 therapy may increase resilience to stress and preserve hippocampal function in women experiencing large fluctuations in plasma estrogen levels.
