The association between early menopause and risk of ischaemic heart disease: Influence of Hormone Therapy

Unilateral Oophorectomy and Age at Natural Menopause: A Longitudinal Community-Based Cohort Study

OBJECTIVE

To determine the association between unilateral oophorectomy (UO) and age at natural menopause.

DESIGN

Secondary analysis of survey data from Alberta's Tomorrow Project (2000-2022).

SETTING

Prospective cohort study in Alberta, Canada.

POPULATION

23 630 women; 548 experienced UO and 23 082 did not experience UO.

METHODS

Flexible parametric survival analysis was used to analyse age at natural menopause, and logistic regression was used to analyse early menopause and premature ovarian insufficiency by UO status, controlling for birth year, parity, age at menarche, past infertility, hormonal contraceptive use and smoking.

MAIN OUTCOME MEASURES

Age at natural menopause occurred by a final menstrual period without medical cause and sub-classified as early menopause (< 45 years) and premature ovarian insufficiency (< 40 years).

RESULTS

Compared to no UO, any UO was associated with elevated risk of earlier age at natural menopause, which was strongest in early midlife (adjusted HR at age 40 1.71, 95% CI 1.31-2.19) and diminished over time. Compared to age 55 years at UO, risks of earlier age at natural menopause were largest and uniform in magnitude when UO occurred between approximately ages 20-40 years (adjusted HR for UO at age 30 2.32, 1.46-3.54) and then diminished as age at UO approached the average age at natural menopause. Any UO was associated with higher odds of early menopause (adjusted OR 1.90, 1.30-2.79) and premature ovarian insufficiency (adjusted OR 3.75, 1.72-8.16).

CONCLUSIONS

Unilateral oophorectomy is associated with earlier age at natural menopause, particularly when performed before 40 years of age.

Effect of Early Menopause and Hormone Replacement Therapy on Aortic Stenosis Progression

BACKGROUND

Early menopause has been associated with several cardiovascular diseases. Its effect on the progression of aortic stenosis (AS) remains unknown. We conducted an analysis to examine the effect of early menopause without hormone replacement therapy (HRT) on the progression of AS in postmenopausal women with AS.

METHODS

This subanalysis included 33 female patients with at least mild AS (mean age 65 ± 10 years) who were prospectively enrolled in the Metabolic Determinants of the Progression of Aortic Stenosis (PROGRESSA) study (NCT01679431). Anatomical assessment of AS was performed using multidetector computed tomography, whereas hemodynamic assessment of AS was performed using Doppler echocardiography.

RESULTS

Over a median follow-up of 2 (25th-75th percentiles, 1-4) years, early menopausal women without HRT showed faster progression of aortic valve calcification (AVC; median, 100 [25th-75th percentiles, 58-130] vs 23 [25th-75th percentiles, 2-71] arbitrary units per year; P = 0.03); mean pressure gradient (median, 2.37 [25th-75th percentiles, 0.82-3.61] vs 0.33 [25th-75th percentiles, 0.01-1.78] mm Hg per year; P = 0.04) and aortic valve area indexed to body surface area (median, -0.12 [25th-75th percentiles, -0.23 to 0.002] vs -0.004 [25th-75th percentile, -0.07 to 0.08] cm2/m2/y; P = 0.07). In multivariate analysis adjusted for several clinical, echocardiographic, and anatomic factors, early menopause without HRT remained independently associated with faster AVC progression (P = 0.003). Women who received HRT showed a slower progression of AVC compared with those who never received HRT (median, 62 [25th-75th percentile, 2-100] vs 20 [25th-75th percentile, 10-42] arbitrary units per year; P = 0.13). Multivariate analysis also showed that AVC progressed less rapidly in women who received HRT (P = 0.04).

CONCLUSIONS

In this study of postmenopausal women with AS, early menopause without HRT was associated with faster progression of AS, anatomically and hemodynamically. However, the use of HRT was associated with slower progression of AS.

Female-specific risk factors for cardiovascular disease: an update

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. While it was previously believed that men have greater susceptibility to CVD, recent research suggests that women face an increased risk of CVD after the onset of menopause, primarily due to the loss of the protective effects of estrogens. Premature ovarian insufficiency (POI), polycystic ovarian syndrome (PCOS), and gestational factors, such as gestational diabetes mellitus (GDM), recurrent pregnancy loss, preterm delivery, and preeclampsia, are specific reproductive disorders that may contribute to an elevated risk of CVD at earlier ages, i.e., before the onset of menopause. This suggests that women with these conditions should be closely monitored for CVD risk factors even before reaching menopause. Such early intervention may help reduce the incidence of CVD and improve overall cardiovascular health in this population. The precise pathophysiological mechanism underlying the development of CVD in women with menopause, premature POI, PCOS, and gestational factors remains elusive. This review article seeks to elucidate the latest research on the relationship between these conditions and CVD in women, aiming to explore the underlying pathogenic mechanisms contributing to this association.

Coronary Artery Calcium Scores After Prophylactic Premenopausal Bilateral Salpingo-Oophorectomy

Background

Premenopausal risk-reducing salpingo-oophorectomy (RRSO) in women at high familial risk of ovarian cancer leads to immediate menopause. Although early natural menopause is associated with increased cardiovascular disease risk, evidence on long-term cardiovascular disease risk after early surgical menopause is scarce.

Objectives

We sought to determine the long-term influence of the timing of RRSO on the development of coronary artery calcium (CAC), an established marker for cardiovascular disease risk.

Methods

We conducted a cross-sectional study (N = 733) nested in a nationwide cohort of women at high familial risk of ovarian cancer. In women aged 60-70 years (n = 328), we compared CAC scores between women with a premenopausal RRSO (age ≤45 years) and women with a postmenopausal RRSO (age ≥54 years), using multivariable Poisson analyses. Within the premenopausal RRSO group (n = 498), we also examined the effect of age at RRSO. In addition, we compared the premenopausal RRSO group with an external reference cohort (n = 5,226).

Results

Multivariable analyses showed that the prevalence rates of any CAC (CAC >0), at least moderate CAC (CAC >100), and severe CAC (CAC >400) were comparable between the premenopausal and postmenopausal RRSO groups (relative risk [RR]: 0.93; 95% CI: 0.75-1.15 for any CAC; RR: 0.71; 95% CI: 0.43-1.17 for at least moderate CAC; RR: 0.81; 95% CI: 0.30-2.13 for severe CAC). There was no difference in CAC between the premenopausal RRSO group and a similar aged reference cohort. Timing of premenopausal RRSO (early premenopausal RRSO [<41 years] vs late premenopausal RRSO [41-45 years]) did not affect the outcomes.

Conclusions

Our results do not show a long-term adverse effect of surgical menopause on the development of CAC.

Type of menopause, age of menopause and cardiovascular disease: a cross-sectional study based on data from Rafsanjan cohort study

BACKGROUND

Cardiovascular disease is the leading cause of death among women, but sex-specific risk factors are incompletely understood. In this study, we aimed to assess the associations between the type of menopause, and age at natural menopause with the odds of cardiovascular disease (CVD), and coronary heart disease (CHD).

METHODS

This cross-sectional study is a part of data from the Rafsanjan Cohort Study (RCS) which is a branch of the Prospective Epidemiological Research Studies in Iran (PERSIAN). A sample of 1767 postmenopausal women were included. The diagnosis for CVD and CHD was based on self-report questionnaires. Menopause age was categorized as < 40, 40-44, 45-49, and ≥ 50. Also, the menopause types were classified as natural and induced menopause (surgery or chemotherapy). The association was evaluated by logistic regressions.

RESULTS

The menopause age < 40 years had higher odds of CVD compared to women with menopause age > 40 years (OR: 2.66; 95%CI 1.29-5.48). Women with induced menopause had higher odds of CVD compared to women with natural menopause (OR = 1.44, 95% CI 1.04-1.98). In terms of the odds of CHD, the results showed that the odds of CHD increased in menopause age < 40 years and induced menopause compared to reference groups (OR: 2.49, 95% CI 1.15-5.37, OR = 1.48; 95% CI 1.06-2.07, respectively).

CONCLUSION

Premature menopause and induced menopause should be considered as important risk factors for CVD, and CHD. Health policymakers should pay more attention to the type of menopause and the age of menopause in postmenopausal women to predict the risk of CVD and preventive strategies.

Replacement with sex steroids in hypopituitary men and women: implications for gender differences in morbidities and mortality

Hypopituitarism is a heterogenous disorder characterised by a deficiency in one or more anterior pituitary hormones. There are marked sex disparities in the morbidity and mortality experienced by patients with hypopituitarism. In women with hypopituitarism, the prevalence of many cardiovascular risk factors, myocardial infarction, stroke and mortality are significantly elevated compared to the general population, however in men, they approach that of the general population. The hypothalamic-pituitary-gonadal axis (HPG) is the most sexually dimorphic pituitary hormone axis. Gonadotropin deficiency is caused by a deficiency of either hypothalamic gonadotropin-releasing hormone (GnRH) or pituitary gonadotropins, namely follicle-stimulating hormone (FSH) and luteinising hormone (LH). HPG axis dysfunction results in oestrogen and testosterone deficiency in women and men, respectively. Replacement of deficient sex hormones is the mainstay of treatment in individuals not seeking fertility. Oestrogen and testosterone replacement in women and men, respectively, have numerous beneficial health impacts. These benefits include improved body composition, enhanced insulin sensitivity, improved atherogenic lipid profiles and increased bone mineral density. Oestrogen replacement in women also reduces the risk of developing type 2 diabetes mellitus. When women and men are considered together, untreated gonadotropin deficiency is independently associated with an increased mortality risk. However, treatment with sex hormone replacement reduces the mortality risk comparable to those with an intact gonadal axis. The reasons for the sex disparities in mortality remain poorly understood. Potential explanations include the reversal of women's natural survival advantage over men, premature loss of oestrogen's cardioprotective effect, less aggressive cardiovascular risk factor modification and inadequate oestrogen replacement in women with gonadotropin deficiency. Regrettably, historical inertia and unfounded concerns about the safety of oestrogen replacement in women of reproductive age have impeded the treatment of gonadotropin deficiency.

Age at natural menopause and associated factors with early and late menopause among Chinese women in Zhejiang province: A cross-sectional study

OBJECTIVES

Menopause is a significant life transition for women, impacting their physical and psychological health. The age at natural menopause (ANM) and its associated factors have differed by race and region. This study aimed to investigate ANM and associated factors of early and late menopause among Chinese women in Zhejiang province.

METHODS

A cross-sectional study was conducted using a multi-stage stratified cluster sampling method to recruit 8,006 women aged 40-69 years who had resided in Zhejiang province for over 6 months between July 2019 and December 2021. Self-reported ANM and sociodemographics, lifestyle behaviors, reproductive history, and health-related factors were collected using questionnaires in face-to-face surveys. ANM were categorized into three groups: early menopause (<45 years), normal menopause (45-54 years), and late menopause (≥55 years). Kaplan-Meier survival analysis was utilized to calculate the median ANM. Multivariable multinomial logistic regression was employed to explore the associated factors of early menopause and late menopause.

RESULTS

A total of 6,047 women aged 40-69 years were included for survival analysis, with 3,176 of them for the regression analysis. The overall median ANM was 51 years (Inter-quartile range [IQR]: 51-52). Women who were smokers (odds ratio [OR]:4.54, 95% confidence interval [CI]:1.6-12.84), had irregular menstrual cycles (OR:1.78, 95% CI:1.12-2.83) and hypertension (OR:1.55, 95% CI:1.09-2.21) had a higher odds ratio of early menopause, while central obesity (OR:1.33, 95% CI:1.03-1.73) and hyperlipidemia (OR:1.51, 95% CI:1.04-2.18) were factors associated with late menopause.

CONCLUSIONS

This study revealed the associations between ANM and various factors among Chinese women. These factors included socio-demographic factors such as age; life behavior factors like current or prior smoking status; reproductive history factors such as irregular menstrual cycles, miscarriages, and breastfeeding; and health-related factors like central adiposity, hypertension, and hyperlipidemia. These findings provided a basis for understanding factors associated with ANM.

Sex and sex steroids as determinants of cardiovascular risk

There are considerable sex differences regarding the risk of cardiovascular disease (CVD), including arterial hypertension, coronary artery disease (CAD) and stroke, as well as chronic renal disease. Women are largely protected from these conditions prior to menopause, and the risk increases following cessation of endogenous estrogen production or after surgical menopause. Cardiovascular diseases in women generally begin to occur at a later age than in men (on average with a delay of 10 years). Cessation of estrogen production also impacts metabolism, increasing the risk of developing obesity and diabetes. In middle-aged individuals, hypertension develops earlier and faster in women than in men, and smoking increases cardiovascular risk to a greater degree in women than it does in men. It is not only estrogen that affects female cardiovascular health and plays a protective role until menopause: other sex hormones such as progesterone and androgen hormones generate a complex balance that differentiates heart and blood vessel function in women compared to men. Estrogens improve vasodilation of epicardial coronary arteries and the coronary microvasculature by augmenting the release of vasodilating factors such as nitric oxide and prostacyclin, which are mechanisms of coronary vasodilatation that are more pronounced in women compared to men. Estrogens are also powerful inhibitors of inflammation, which in part explains their protective effects on CVD and chronic renal disease. Emerging evidence suggests that sex chromosomes also play a significant role in shaping cardiovascular risk. The cardiovascular protection conferred by endogenous estrogens may be extended by hormone therapy, especially using bioidentical hormones and starting treatment early after menopause.

Insufficient use of menopausal hormone therapy in Swedish women with early or premature menopause caused by bilateral oophorectomy: a register-based study

OBJECTIVE

To investigate the use of menopausal hormone therapy (MHT) in premenopausal women after bilateral oophorectomy.

DESIGN

Retrospective register-based cohort study.

SETTING

Sweden.

POPULATION

Swedish women aged 35-44 years without malignancy who underwent bilateral oophorectomy in 2005-2020 were identified using The Swedish National Quality Register of Gynaecological Surgery (GynOp).

METHODS

Data from GynOp were cross-linked with data on dispensed drugs extracted from the Swedish Prescribed Drug Register.

MAIN OUTCOME MEASURES

Proportion of women dispensed MHT at least once within 1 year after surgery. Repeated treatment episodes were defined, and the proportion of 'person time' covered by dispensations was analysed.

RESULTS

In total, 1231 of all women (n = 1706) were dispensed MHT at some point after surgery, with 1177 women dispensed MHT within 1 year. This proportion increased from 64% in 2005 to 84% in 2019 (p < 0.001). In the total population, 4537 'treatment years' transpired, corresponding to 43% of the mean time covered. In women dispensed MHT within 1 year, the proportion of time covered was 63%.

CONCLUSIONS

Only 69% of all women without malignancy of any kind who underwent bilateral oophorectomy were dispensed MHT within 1 year after surgery, and the duration of treatment was limited. It is important to study further the reasons behind the low dispensation rate in this group to increase adherence to current treatment guidelines, improve quality of life, and avoid increased morbidity and mortality.

The Association of Early Menopause with Increased Risk of Acute Myocardial Infarction: The INTERHEART China Study

Background and Aim: Little is known about whether early menopause in Chinese ethnicity is associated with acute myocardial infarction (AMI). We aimed to determine whether self-reported early menopause (either surgical or natural menopause at an age <50 year) was associated with first AMI in Chinese women. Methods: The study population was from the INTERHEART China Study, part of the INTERHEART global study. INTERHEART global study was a standardized case-control study that was designed to evaluate the risk factors for first AMI among 52 countries. Data for demographic factors, education, income, and cardiovascular risk factors were obtained by structured questionnaires. A standard set of questions that inquired about menstrual history was included in the interview. Results: Of the 1,771 Chinese women, 1,563 (88.3%) reported either natural or surgical menopause. In univariate logistic regression model, women with early menopause had higher risk of AMI (odds ratio [OR]: 1.51; 95% confidence interval [CI]: 1.23-1.87). After controlling for age, birth control measures, type of menopause, and other traditional risk factors (including waist/hip ratio, lifestyle factors, history of hypertension and diabetes, psychosocial factors, and apolipoprotein B [ApoB]/A1 [ApoA1]), the risk for AMI remained (OR: 1.36; 95% CI: 1.03-1.79). The population attributable risk for AMI in women with early menopause at <50 years was 10.1% (95% CI: 4.0-20.0) compared with women who had menopause at ≥50 years. Conclusion: Early menopause is associated with increased risk of AMI in Chinese women, independent of other traditional coronary heart disease risk factors.

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.

Study on depletion of ovarian function and late-life chronic diseases in India

OBJECTIVE

The current study aims to understand premature and early menopausal age in association with chronic conditions.

METHODS

The present cross-sectional study analyzed nationally representative data from LASI (Longitudinal Aging Study in India) from 2017 to 2018. Bivariate analysis including cross-tabulation and χ2 tests were performed. Further multiple regression analysis was performed, using the generalized linear model of logit link.

RESULTS

Approximately 2533 (8%) older women reported that they had experienced premature menopause (before age 40), while 3889 (12.4%) reported having early menopause (age 40-44). The likelihood of a woman with premature menopause developing cardiovascular diseases (CVDs) is 15% higher (adjusted odds ratio [AOR], 1.15; P < 0.05) than those who do not experience premature menopause, while women with early menopause have a 13% higher risk (AOR, 1.13; P < 0.05). For women who experienced premature menopause and were also smokers, the probability of developing CVDs was higher. Other chronic diseases such as bone or joint problems, diabetes, and eye vision problems were also shown to be significant health problems among women who had premature ovarian failure.

CONCLUSION

Our results show significant association between women with premature or early depletion of ovarian function and chronic health conditions such as cardiovascular diseases, bone or joint problems, vision problems, and neurological or psychiatric disorders at their later life ages. Comprehensive strategies in the form of lifestyle changes may regulate hormonal levels and allow the body to reach menopause at the appropriate age.

Long-Term Follow Up of Sexual Function and Steroid Levels in Women after Perimenopausal Hysterectomy with or without Concomitant Oophorectomy

Hysterectomy, most often performed because of bleeding disorders or uterine leiomyoma, is one of the most common major surgical procedures in women and is usually performed during the perimenopausal period on ages 45-55 years. Hysterectomy may be combined with bilateral salpingo-oophorectomy, as a risk-reducing procedure to minimize the risk of ovarian cancer. An open question is whether concomitant oophorectomy, with cessation of ovarian androgen secretion, has any long-term effects on sexual function. In the present prospective cohort study of women undergoing benign hysterectomy, the long-term (10-12 years) effects on sexual function and changes in sex hormone levels were investigated in women having undergone perimenopausal hysterectomy, with or without concomitant bilateral salpingo-oophorectomy. Originally, 491 women (mean age around 50 years) were operated with (patient preference) either only hysterectomy (HYST) or hysterectomy plus bilateral salpingo-oophorectomy (HYST + BSO), and 441 women (90%; HYST; n = 271 and HYST + BSO; n = 170) completed a one-year survey. In the present study, 185 women (42%) of the cohort with one-year follow up participated in the long-term follow up after 10-12 years. Follow-up was with the 10-item McCoy Female Sex Questionnaire and blood analysis of levels of testosterone, estradiol and sexual-hormone-binding globulin. The results showed that specific aspects of sexual function were lower after HYST + BSO compared to HYST 10-12 years after surgery. These lowered items were frequency of sexual fantasies, enjoyment of sexual activity, sexual arousal, and orgasmic frequency. No long-term differences in sex hormone levels were found between the two groups. In conclusion, some items related to sexual function were lower after HYST + BSO in a long-term perspective study, although the levels of testosterone were unaltered. This finding may have implications for clinical recommendations concerning prophylactic salpingo-oophorectomy or for hysterectomy during the perimenopausal age.

Characteristics of retinal image associated with premature ovarian insufficiency: a case- control study

PURPOSE

To establish an early clinical diagnosis model based on the retinal vascular features associated with POI, supplying a non-invasive way for accurately and early predicted the risk of POI.

METHODS

A total of 78 women with spontaneous POI and 48 healthy women were recruited from the Affiliated Shenzhen Maternity & Child Healthcare Hospital in the study. Retinal characteristics were analyzed using an automated retinal image analysis system. Binary logistic regression was used to identify POI cases and develop predictive models.

RESULTS

Compared to the normal group, the POI group had larger central retinal artery equivalent (CRAE) (P = 0.006), central retinal vein equivalent (CRVE) (P = 0.001), index of venules asymmetry (Vasym) (P = 0.000); larger bifurcation angles of arterioles (Aangle) (P = 0.001), bifurcation coefficient of venule (BCV) (P = 0.001) and more obvious arteriovenous nipping (Nipping) (P = 0.005), but lower arteriole-to-venule ratio (AVR) (P = 0.012). In the POI group, the odds ratio (OR) of Vasym was 6.72e-32 (95% C.I. 4.62e-49-9.79e-15, P = 0.000), the OR of BCV was 5.66e-20 (95% C.I. 1.93e-34-.0000, P = 5.66e-20) and the OR of Nipping was 6.65e-06 (95% C.I. 6.33e-10-.0698, P = 0.012). Moreover, the area under the ROC curve for the binary logistic regression with retinal characteristics was 0.8582, and the fitting degree of regression models was 60.48% (Prob > chi-square = 0.6048).

CONCLUSION

This study demonstrated that retinal image analysis can provide useful information for POI identification and certain characteristics may help with early clinical diagnosis of POI.

Barriers to hormone therapy following prophylactic bilateral salpingo-oophorectomy in BRCA1/2 mutation carriers

OBJECTIVE

This study aimed to identify barriers to hormone therapy (HT) use among women with BRCA1/2 mutations after prophylactic bilateral salpingo-oophorectomy (BSO).

METHODS

A cross-sectional, electronic survey was conducted of BRCA1/2 mutation carriers at Women and Infants Hospital, Yale Medical Center, Hartford Healthcare, and Maine Medical Center. This study was a subanalysis of a subset of female BRCA1/2 mutation carriers who had undergone a prophylactic BSO. Data were analyzed using the Fisher's exact test or t test.

RESULTS

We performed a subanalysis of 60 BRCA mutation carriers who underwent a prophylactic BSO. Only 24 women (40%) reported ever using HT. HT use was higher in women who underwent their prophylactic BSO at age younger than 45 years (51% vs. 25%, P = 0.06). Among all women who had a prophylactic BSO, the majority (73%) reported that a provider talked to them about using HT. Two thirds reported having seen contradictory information in the media about long-term consequences of HT. Seventy percent listed their provider as the primary influence in their decision to start HT. The most common reasons for not starting HT included it not being recommended by their physician (46%) and that it was not necessary (37%).

CONCLUSIONS

BRCA mutation carriers frequently undergo prophylactic BSO at young ages, and less than half report using HT. This study highlights barriers to HT use, such as patient fears and physician discouragement, and identifies potential areas to improve educational efforts.

The impact of obesity on vaginal hysterectomy and laparoscopically-assisted vaginal hysterectomy outcomes: A randomised control trial

OBJECTIVES

This prospective randomised control trial aimed to compare outcome measures of vaginal hysterectomy (VH) and laparoscopically-assisted vaginal hysterectomy (LAVH) in obese vs. non-obese women undergoing hysterectomy for benign uterine conditions with a non-prolapsed uterus. The primary objective of the study was to estimate operation time, uterine weight and blood loss amongst obese and non-obese patients undergoing VH and LAVH. The secondary objective was to determine any difference in hospital stay, the need for post-operative analgesia, intra- and immediate post-operative complications, and the rate of conversion to laparotomy for obese vs. non-obese patients undergoing VH and LAVH.

STUDY DESIGN

A prospective randomised control study was undertaken in the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). Women admitted between January 2017 and December 2019 for hysterectomy due to benign conditions, meeting the inclusion criteria set by the unit (vaginally accessible uterus, uterine size ≤ 12 weeks of gestation or ≤ 280gr on ultrasound examination, pathology confined to the uterus) were included in the study. The VH procedures were performed by the residents in training, under the supervision of specialists with large experience in vaginal surgery. All the LAVHs were performed by one surgeon (AC). In addition to the patient characteristics and surgical approach to hysterectomy, operative time, estimated blood loss, uterine weight, length of hospital stay, intra-operative and immediate post-operative complications were also recorded in obese and non-obese patient groups and comparatively analysed.

RESULTS

A total of 227 women were included in the study. 151 patients underwent VH and 76 LAVH, upon randomisation on a 2:1 basis, reflecting the habitual proportion of hysterectomy cases in the Urogynaecology and Endoscopy Unit at CMJAH. No significant differences were found in mean shift of pre-operative to post-operative serum haemoglobin, uterine weight, intra- and immediate post-operative complications, and convalescence period when comparing obese and non-obese patients in both the VH and LAVH groups. There was a statistically significant difference in operating time between the two procedures. The LAVHs took longer compared to the VHs to be performed (62.8 ± 9.3 vs. 29.9 ± 6.6 min in non-obese patients, and 62.7 ± 9.8 vs 30.0 ± 6,9 min for obese patients). All VHs and LAVHs were successfully accomplished without major complications.

CONCLUSION

VH and LAVH for the non-prolapsed uterus is a feasible and safe alternative for obese patients demonstrating similar perioperative outcome measures as non-obese women undergoing VH and LAVH. Where possible, VH should be preferred to LAVH as it is a safe route of hysterectomy, with operation time being significantly shorter.

Cardiovascular Risk Factors in Premature Ovarian Insufficiency using Hormonal Therapy

OBJECTIVE

 Premature ovarian insufficiency (POI) is characterized by early hypoestrogenism. An increased risk of cardiovascular (CV) disease is a long-term consequence of POI. A challenge of hormone therapy (HT) is to reduce the CV risk.

METHODS

 Cross-sectional study with lipid profile analysis (total cholesterol, LDL-C, HDL-C, VLDL-C and triglycerides), blood glucose levels and arterial blood pressure of women with POI using HT, compared with age and BMI-matched women with normal ovarian function (controls).

RESULTS

 The mean age and BMI of 102 POI patients using HT and 102 controls were 37.2 ± 6.0 and 37.3 ± 5.9 years, respectively; 27.0 ± 5.2 and 27.1 ± 5.4 kg/m². There wasn't difference between groups in arterial systolic and diastolic blood pressure, blood glucose levels, total cholesterol, LDL-C, VLDL-C and triglycerides. HDL-C levels were significantly higher in the POI group (56.3 ± 14.6 and 52 ± 13.9mg/dL; p = 0.03). Arterial hypertension was the most prevalent chronic disease (12% in the POI group, 19% in the control group, p = ns), followed by dyslipidemia (6 and 5%, in POI and control women).

CONCLUSION

 Women with POI using HT have blood pressure levels, lipid and glycemic profile and prevalence of hypertension and dyslipidemia similar to women of the same age and BMI with preserved gonadal function, in addition to better HDL levels.

All-cause and cardiovascular mortality after hysterectomy and oophorectomy in a large cohort (HUNT2)

INTRODUCTION

Hysterectomy and bilateral oophorectomy are common major surgical procedures that have been associated with increased mortality risk. We aimed to assess the association of hysterectomy and/or bilateral oophorectomy with all-cause and cardiovascular mortality in a Norwegian population.

MATERIAL AND METHODS

Cohort study with data from The Trøndelag Health Study (HUNT2) linked to the Norwegian Cause of Death Registry, with follow-up from 1996 until 2014 or death. The unexposed group (n = 18 673) included women with both their ovaries and uterus intact, while the two exposed groups included women with hysterectomy alone (n = 1199), or bilateral oophorectomy with or without hysterectomy (n = 907). We compared mortality in exposed vs unexposed groups and adjusted for relevant covariates by Cox regression. Further, we performed analyses stratified by age at surgery (≤39, 40-52, ≥53 years) and subgroup analyses among women ≤52 years of age at inclusion.

RESULTS

Among the 47 312 women in HUNT2 (1995-1997), 20 779 provided complete information regarding gynecological surgery and previous health. The hysterectomy group had increased all-cause mortality (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.06-1.58) and cardiovascular mortality (HR 1.47, 95% CI 1.09-1.97). We found no significant association between bilateral oophorectomy and all-cause or cardiovascular mortality in the total population. However, among women ≤52 years at inclusion, cardiovascular mortality was increased in the hysterectomy group (HR 2.71, 95% CI 1.19-6.17) with a similar, but less precise estimate in the bilateral oophorectomy group (HR 2.42, 95% CI 0.84-6.93).

CONCLUSIONS

Hysterectomy was associated with increased all-cause and cardiovascular mortality, whereas bilateral salpingo-oophorectomy was not. Among women ≤52 years at inclusion, both hysterectomy and bilateral oophorectomy were associated with a twofold increased risk of cardiovascular mortality, but the results were imprecise. Women after hysterectomy and/or bilateral salpingo-oophorectomy constitute a group with increased cardiovascular mortality that may need closer attention to cardiovascular disease risk from the healthcare system to ensure timely and effective preventive interventions.

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.

The risk of long-term cardiometabolic disease in women with premature or early menopause: A systematic review and meta-analysis

Background

Transition into menopause is associated with an increased risk of cardiovascular disease (CVD). However, it is unclear whether the association exists between premature menopause (defined as age at menopause 40 years) or early menopause (defined as age at menopause 40-45 years) and CVD or cardiovascular risk factors. The aim of this review was to comprehensively evaluate and meta-analyze the most reliable evidence about the relationship between menopausal age and the risk of long-term cardiometabolic disease.

Methods

A comprehensive literature search of the PubMed, Web of Science, and Embase databases from inception to October 1, 2022, for titles and abstracts with a restriction to English language papers led to the discovery of the studies. Data are expressed as the Hazard Ratio (HR) with 95% confidence intervals (CI). The degree of heterogeneity was measured using the I-square (I ²) index.

Results

921,517 participants from 20 cohort studies published between 1998 and 2022 were considered. Compared to women with menopause at age >45 years, women with premature menopause (PM) or early menopause (EM) had a higher risks of type 2 diabetes (RR: 1.32, 95% CI: 1.08-1.62; RR: 1.11, 95% CI: 0.91-1.36, respectively), hyperlipidemia (RR: 1.21, 95% CI: 1.05-1.39; RR: 1.17, 95% CI: 1.02-1.33, respectively), coronary heart disease (RR: 1.52, 95% CI: 1.22-1.91; RR: 1.19, 95% CI: 1.07-1.32, respectively), stroke (RR: 1.27, 95% CI: 1.02-1.58; RR: 1.13, 95% CI: 0.97-1.32, respectively) and total cardiovascular event (RR: 1.36, 95% CI: 1.16-1.60; RR: 1.14, 95% CI: 0.97-1.35, respectively). No difference was found for hypertension in PM or EM women (RR: 0.98, 95% CI: 0.89-1.07; RR: 0.97, 95% CI: 0.91-1.04, respectively). Additionally, we also found that PM women, but not EM women, were linked with an increased risk of ischemic and hemorrhagic stroke. However, this is not in line with the conclusion that both PM and EM had a higher risk of total stroke.

Conclusion

Women with PM or EM have a higher risk of developing long-term CVD, compared to women with menopause at age >45 years. Therefore, we recommend early lifestyle interventions (e.g., maintaining a healthy lifestyle) and medical treatments (e.g., timely initiation of menopausal hormone therapy) to decrease the risk of cardiometabolic disease in early or premature menopausal women.

Diastolic dysfunction and sex-specific progression to HFpEF: current gaps in knowledge and future directions

Diastolic dysfunction of the left ventricle (LVDD) is equally common in elderly women and men. LVDD is a condition that can remain latent for a long time but is also held responsible for elevated left ventricular filling pressures and high pulmonary pressures that may result in (exercise-induced) shortness of breath. This symptom is the hallmark of heart failure with preserved ejection fraction (HFpEF) which is predominantly found in women as compared to men within the HF spectrum. Given the mechanistic role of LVDD in the development of HFpEF, we review risk factors and mechanisms that may be responsible for this sex-specific progression of LVDD towards HFpEF from an epidemiological point-of-view and propose future research directions.

Chinese patent medicines combined with hormone replacement therapy for premature ovarian failure: A Bayesian network meta-analysis

Objective

The objective of this study was to compare the efficacy differences between Chinese patent medicines combined with hormone replacement therapy (HRT) in the treatment of premature ovarian failure (POF) by the Bayesian network meta-analysis (NMA) method.

Methods

Randomized controlled trials (RCTs) reporting Chinese patent medicine combined with HRT for POF included Medline (via PubMed), Embase, Cochrane Library, China National Knowledge Infrastructure Database (CNKI), Wanfang Database (Wanfang), VIP Database (VIP), and China Biology Medicine Database (CBM) from the inception of the databases to July 2022. Two researchers independently screened the articles, extracted data, and evaluated the quality. The literature that met the inclusion criteria was screened out, the quality and risk of bias of the included studies were assessed according to the Cochrane 5.1 manual and RevMan 5.4, and NMA was performed using Stata 15.0 and R software.

Results

Sixty-four RCTs involving 5,675 individuals containing 12 oral Chinese patent medicines combined with HRT were enrolled into the current NMA. The results showed that when compared with patients using only HRT, the total clinical response rate is greater in patients using HRT combined with one of these 12 oral Chinese patent medicines. Among them, Zuogui pills + HRT [odds ratio (OR) = 3.92; 95% credible interval (CrI) = 0.86, 23.84; SUCRA = 73.76%] is most likely to be the best intervention, and the suboptimal intervention is Guishen pills + HRT (OR = 3.22, 95% CrI = 1.16, 9.44, SUCRA = 70.60%).

Conclusion

Chinese patent medicines combined with HRT were more effective than HRT alone in the treatment of POF. Zuogui pills are good at decreasing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and more effective in the improvement of total clinical response rate; Xuefu Zhuyu capsule is also good at decreasing FSH. Ziheche capsule is an expert in improving estradiol level; Kuntai capsule shows the lowest incidence of adverse reactions. However, the quality of the literature included in this study is relatively low, so it may affect the results of the study. Therefore, higher quality and multi-center trial would be necessary for supporting these results.

Early menopause and a low body mass index are associated with an increased risk of coronary heart disease in Japanese women

OBJECTIVE

The primary objective was to investigate the association between early menopause and cardiovascular disease (CVD) prevalence in Japanese women. The secondary objective was to ascertain the association with CVD risk factors.

METHODS

In this cross-sectional study, 7,239 naturally menopausal women from the Yamagata Cohort Study who completed an annual health visit and questionnaire between 2009 and 2015 were divided into three groups according to their age at menopause (women experiencing menopause at <45, 45-49 y, and ≥ 50 y). The diagnosis of coronary heart disease (CHD) and stroke were made by self-report, while hypertension, hyperlipidemia, and diabetes mellitus, were diagnosed by vital signs and laboratory parameters. Logistic regression analysis was used to estimate the associations between age at menopause and CVD prevalence and CVD risk factors.

RESULTS

A total of 354 (4.9%) and 156 (2.2%) women reported a history of CHD and stroke, respectively. Women experiencing menopause at <45 years had a higher prevalence of CHD than those experiencing menopause at ≥50 years (OR 1.77, 95% CI 1.07-2.90; P = 0.023). Stroke, hypertension, diabetes mellitus, and hyperlipidemia were equally prevalent among the three groups. Significant interactions were observed between age at menopause and body mass index (BMI) (P = 0.025) and parity (P = 0.025). Among those with a BMI < 18.5 or parity ≥2, women experiencing menopause at <45 years had a significantly higher prevalence of CHD than those experiencing menopause at ≥50 years.

CONCLUSION

Early menopause and low BMI were associated with CHD in Japanese women.

Impact of Global Consensus Statement on compliance with hormonal therapy for surgical menopause

OBJECTIVE

Initiation of and compliance with menopausal hormonal therapy (MHT) have been dropping due to the 2002 Women's Health Initiative (WHI) publication. We evaluated the change in practice of MHT for surgical menopause after implementing the 2013 'Global Consensus Statement on MHT' to our institutional guideline.

METHODS

A retrospective study was conducted in surgically menopausal women newly registering at the Siriraj Menopause Clinic in a university hospital, Thailand, from 1995 to 2013. The patients were categorized into four groups according to periods of MHT initiation: 1995-1998 (control), 2000-2003 (WHI affected), 2005-2008 (post WHI) and 2010-2013 (Global Consensus Statement affected). Their 3-year compliance with MHT was compared using forward stepwise regression analysis.

RESULTS

There were 288, 156, 107 and 104 cases in the 1995-1998, 2000-2003, 2005-2008 and 2010-2013 groups. Their mean age at surgery was 42.8 ± 4.7 years. After the first, second and third years, overall compliance was 82.4%, 70.9% and 61.2%, respectively. The 3-year compliance drastically dropped in the 2000-2003 group, and then improved to control level in the 2010-2013 group (51.9% vs. 77.9%, p = 0.035).

CONCLUSION

The initiation of MHT continuously dropped during 2000-2013; however, compliance with MHT initiated during 2010-2013 improved after implementing the 2013 'Global Consensus Statement on MHT' to our institutional guideline. Each institute should have a strategy to encourage the initiation of and compliance with MHT for surgical menopause to achieve long-term health benefits.

Standardizing the surgical management of benign ovarian tumors in children and adolescents: A best practice Delphi consensus statement

AIM

No widely agreed consensus protocols exist for the management of benign ovarian tumors (BOT) in children. This presents a substantial risk for suboptimal management. We aimed to generate multispecialty consensus guidance to standardize surgical management and provide a clear follow-up protocol for children with BOTs.

METHODS

Prospective two-round confidential e-Delphi consensus survey distributed among multispecialty expert panel; concluded by two semistructured videoconferences.

MAIN RESULTS

Consensus was generated on these core outcome sets: preoperative/intraoperative management; follow-up; adolescent gynecology referral. (1) Children with BOTs should receive the same management as other patients with potentially neoplastic lesions: Preoperative discussion at a pediatric oncology multidisciplinary meeting to risk stratify tumors, and management by health professionals with expertise in ovarian-sparing surgery and laparoscopy. (2) Ovarian-sparing surgery for BOTs should be performed wherever possible to maximize fertility preservation. (3) Ovarian masses detected during emergency laparoscopy/laparotomy should be left in situ wherever feasible and investigated appropriately (imaging/tumor markers) before resection. (4) Follow-up should be undertaken for all patients after BOT resection. Patients should be offered referral to adolescent gynecology to discuss fertility implications.

CONCLUSION

This best practice Delphi consensus statement emphasizes the importance of managing children with BOTs through a well-defined oncological MDT strategy, in order to optimize risk stratification and allow fertility preservation by ovarian-sparing surgery wherever possible.

Age at natural menopause in women with a history of chronic diseases-A population-based cohort study

OBJECTIVE

This study was carried out to determine whether chronic diseases can influence age at natural menopause (ANM).

STUDY DESIGN AND MAIN OUTCOME MEASURES

This population-based prospective study recruited all eligible women from participants in the Tehran Lipid and Glucose Study (TLGS). The Cox proportional-hazards model (unadjusted and adjusted) was used to assess associations of ANM with chronic diseases, including diabetes mellitus (DM), hypertension (HTN), dyslipidemia, metabolic syndrome (MetS), cardiovascular disease (CVD), chronic kidney disease (CKD), and thyroid disorders, which were not included simultaneously in the model because there were correlations between chronic diseases.

RESULTS

A total of 4662 women, aged 15-50 years, who had not reached menopause at initiation of the TLGS were included. Of these women, 1220 (26.2%) experienced menopause during the study follow-up. In the multivariable Cox regression model adjusted for potential confounders, women with DM [HR:1.75; 95%CI: (1.32, 2.32)], HTN [HR: 2.11; 95%CI: (1.64, 2.72)], MetS [HR: 2.01; 95%CI: (1.57, 2.58)], CVD [HR: 3.02; 95%CI: (1.93, 4.73)], CKD [HR: 2.64; 95%CI: (2.16, 3.22)], and thyroid disorders [HR: 1.41; 95%CI: (1.06, 1.88)] reached menopause earlier, while dyslipidemia was not associated with ANM.

CONCLUSION

This study demonstrates that women with a history of chronic diseases, such as metabolic disorders, cardiovascular events, and CKD, experience menopause earlier than their counterparts without such a history.

Anti-apoptotic effects of diosgenin on ovariectomized hearts

BACKGROUND

The anti-apoptotic effects of diosgenin, a steroid saponin, on hearts in female with estrogen deficiency have been less studied. This study aimed to evaluate the anti-apoptotic effects of diosgenin on cardiac widely dispersed apoptosis in a bilateral ovariectomized animal model.

METHODS

A total of 60 female Wistar rats, aged 6-7 months, were divided into the sham-operated group (Sham), bilateral ovariectomized rats for 2 months, and ovariectomized rats administered with 0, 10, 50, or 100 mg/kg diosgenin daily (OVX, OVX 10, OVX 50, and OVX 100, respectively) in the second month. The excised hearts were analyzed by H&E staining, TUNEL(+) assays and Western Blot.

RESULT

Cardiac TUNEL(+) apoptotic cells, the levels of Fas ligand, Fas death receptors, Fas-associated death domain, active caspase-8, and active caspase-3 (FasL/Fas-mediated pathways) as well as the levels of Bax, Bad, Bax/Bcl2, Bad/p-Bad, cytosolic Cytochrome c, active caspase-9, and active caspase-3 (mitochondria-initiated pathway) were increased in OVX compared with Sham group but those were decreased in OVX 50 compared with OVX.

CONCLUSION

Diosgenin appeared to prevent or suppress ovariectomy-induced cardiac FasL/Fas-mediated and mitochondria-initiated apoptosis. These findings might provide one of the possible therapeutic approaches of diosgenin for potentially preventing cardiac apoptosis in women after bilateral ovariectomy or women with estrogen deficiency.

Pregnancy and Reproductive Risk Factors for Cardiovascular Disease in Women

Beyond conventional risk factors for cardiovascular disease, women face an additional burden of sex-specific risk factors. Key stages of a woman's reproductive history may influence or reveal short- and long-term cardiometabolic and cardiovascular trajectories. Early and late menarche, polycystic ovary syndrome, infertility, adverse pregnancy outcomes (eg, hypertensive disorders of pregnancy, gestational diabetes, preterm delivery, and intrauterine growth restriction), and absence of breastfeeding are all associated with increased future cardiovascular disease risk. The menopause transition additionally represents a period of accelerated cardiovascular disease risk, with timing (eg, premature menopause), mechanism, and symptoms of menopause, as well as treatment of menopause symptoms, each contributing to this risk. Differences in conventional cardiovascular disease risk factors appear to explain some, but not all, of the observed associations between reproductive history and later-life cardiovascular disease; further research is needed to elucidate hormonal effects and unique sex-specific disease mechanisms. A history of reproductive risk factors represents an opportunity for comprehensive risk factor screening, refinement of cardiovascular disease risk assessment, and implementation of primordial and primary prevention to optimize long-term cardiometabolic health in women.

Recurrence and Metachronous Disease in Children with Benign Ovarian Tumors: A Systematic Review of the Literature

AIM

 The majority of ovarian tumors in children are benign, with good prognosis following complete resection. Little is published on the incidence of tumor recurrence and metachronous disease, and follow-up management of children with benign ovarian tumors (BOTs) remains a matter of debate. This systematic review aimed to evaluate the incidence and timing of recurrence and metachronous disease in children with BOTs in pediatric literature.

METHODS

 Comprehensive literature searches of the English literature (PubMed, OVID, EMBASE databases) from inception to present according to the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Outcomes for tumor recurrence and metachronous disease were synthesized.

RESULTS

 Nineteen studies comprising 1,069 patients with BOTs were included in the analysis. All studies were retrospective cohort studies of children less than 18 years old. A total of 56 events of recurrence or metachronous disease were reported in these patients. The overall risk of recurrence/metachronous event occurrence was 5.2%/2.9%. Seventy-five percent of events occurred within the first 4 years following resection.

CONCLUSION

 Although the studies identified are few and heterogeneous, they demonstrate a significant risk of tumor recurrence and metachronous disease for children following resection of a BOT.Especially following total unilateral oophorectomy, these children are at risk of losing the contralateral ovary in case of metachronous disease.Immediate discharge from follow-up, therefore, does not appear safe. The majority of events occurred within the first 4 years following resection. Follow-up for children following resection of a BOT should, therefore, be continued for a minimum of 4 years following surgery. Larger, long-term prospective studies are required to more accurately determine the true incidence and long-term outcomes for children and adolescents with these tumors.

Management of cardiovascular disease in women with premature ovarian insufficiency: critical quality appraisal of clinical guidelines and algorithm development

OBJECTIVES

1) To assess the methodological quality of clinical practice guidelines (CPGs) associated with cardiovascular disease (CVD) in women with premature ovarian insufficiency (POI); 2) to formulate an algorithm to foster the implementation of guidelines by clinicians.

METHODS

A systematic search for CPGs in English and Chinese languages published between 2015 and 2020 was conducted. Assessment was conducted by two reviewers respectively via the Appraisal of Guidelines for Research and Evaluation II instrument. The interappraisal agreement was evaluated. Recommendations pertaining to the management of CVD in women with POI were extracted from high-score CPGs and developed into an algorithm, which was refined on the basis of expert feedback.

RESULTS

A total of 14 CPGs were included. Three CPGs were evaluated as "high quality," with five "average" and six considered "low quality." The consistency of agreement between reviewers was considered as substantial agreement to almost perfect agreement (0.72-0.90). The algorithm consisted of three categories: initial evaluation, management, and subsequent monitoring of CVD in POI. Only "management" had recommendations from all three high-quality CPGs.

CONCLUSIONS

The overall methodological quality of most CPGs regarding CVD in women with POI is moderate to poor. A management algorithm with a clear implementation strategy was developed from high-scoring CPGs. Further research is needed to provide evidence-based health care in this field.

Urinary metals and metal mixtures and timing of natural menopause in midlife women: The Study of Women's Health Across the Nation

BACKGROUND

Exposure to metals and metal mixtures may influence ovarian aging. However, epidemiologic evidence of their potential impact is lacking.

OBJECTIVE

We prospectively examined the associations of 15 urinary metal concentrations and their mixtures with natural menopause in the Study of Women's Health Across the Nation Multi-Pollutant Study.

METHODS

The study population consisted of 1082 premenopausal women from multiple racial/ethnic groups, aged 45-56 years at baseline (1999-2000), with the median follow-up of 4.1 years. Urinary concentrations of 15 metals, including arsenic, barium, cadmium, cobalt, cesium, copper, mercury, manganese, molybdenum, nickel, lead, antimony, tin, thallium, and zinc, were measured at baseline. Natural menopause was defined as the final bleeding episode prior to at least 12 months of amenorrhea, not due to surgery or hormone therapy. Cox proportional hazards models were used to examine associations between individual metal concentrations and timing of natural menopause. The associations between metal mixtures and natural menopause were evaluated using elastic net penalized Cox regression, and an environmental risk score (ERS) was computed to represent individual risks of natural menopause related to metal mixtures.

RESULTS

The median age at natural menopause was 53.2 years. Using the Cox proportional hazards models, the adjusted hazard ratio (HR) (and its 95% confidence interval (CI)) for natural menopause was 1.32 (1.03, 1.67) for arsenic and 1.36 (1.05, 1.76) for lead, comparing the highest with the lowest quartiles of metal concentrations. The predicted ages at natural menopause in the highest and lowest quartiles were 52.7 and 53.5 years for arsenic; and 52.9 and 53.8 years for lead. A significant association between ERS and menopause was also observed. Women in the highest vs. the lowest quartiles of ERS had an HR of 1.71 (1.36, 2.15), equivalent to a 1.6 year earlier median time to natural menopause.

CONCLUSION

This study suggests that arsenic, lead, and metal mixtures are associated with earlier natural menopause, a risk factor for adverse health outcomes in later life.

Resveratrol Enhances the Cytotoxic Activity of Lymphocytes from Menopausal Women

Nutraceuticals and functional foods are the main sources of antioxidants and have positive effects on health through regulation of the redox balance. Accordingly, they represent a useful nutritional source for the prevention of noncommunicable diseases (NCDs). Menopausal women have an increased risk of developing NCDs due to hormonal dysregulation and the ongoing aging process. Accordingly, a healthy lifestyle and good nutritional habits are of utmost importance in this population. Resveratrol (RSV) is a natural polyphenol, and it is used as a nutraceutical given its estrogenic, anti-inflammatory, and antioxidant properties. The aim of this study was to analyze the effects of RSV on the lymphocyte cytotoxicity in menopausal women. Lymphocytes from 13 healthy menopausal women (56.18 ± 4.24 years) were isolated, and then cocultured with hTERT-HME1, a breast cell line with a precancerous phenotype. The results showed that, when treated with RSV, lymphocytes significantly increased the TNF-α production (p < 0.001), the formation of immune synapses (p = 0.009), and the target cell lysis (p = 0.002). No effects were detected in the lymphocyte total antioxidant capacity. In conclusion, RSV might enhance the immune surveillance in menopausal women by increasing the cytotoxic activity of lymphocytes.

Natural menopausal age and cardiovascular disease risk factors in older Chinese women: Guangzhou Biobank Cohort Study

OBJECTIVE

To examine the associations of natural menopausal age with cardiovascular disease risk factors and whether the associations varied by parity in older Chinese women.

METHODS

Information of demographic characteristics, lifestyles, and reproductive factors was collected by face-to-face interview. Framingham Risk Score was used as an indicator of cardiovascular disease risk, with a score ≥ 10% considered as high cardiovascular disease risk (vs low, dichotomous). Multivariable logistic and linear regressions were used to examine the associations of menopausal age with cardiovascular disease risk factors.

RESULTS

Of 18,339 women aged 50+ years, the average (standard deviation) age was 61.8 (6.9) years. Compared with women with menopausal age of 45 to 54 years, after adjustment for multiple potential confounders, women with menopausal age <45 years or ≥55 years had higher Framingham Risk Score (0.93%, 95% confidence interval: 0.40-1.46, and 0.69%, 95% confidence interval: 0.18-1.20, respectively). Women with menopausal age <45 or ≥55 years had higher odds of high cardiovascular disease risk (vs low) (odds ratio [95% confidence interval]:1.26 (1.10-1.44) and 1.17 (1.02-1.33), respectively). The associations of menopausal age with the Framingham Risk Score varied by parity (P for interaction ≤0.001). The Framingham Risk Score was higher in those with one to three parity (<45 y: 1.01 [0.43-1.59]; ≥55 y: 1.14 [0.60-1.68]) and lower for parity ≥4 (<45 y: -0.33 [-1.84 to 1.18]; ≥55 y: -2.02 [-3.82 to -0.22]). In nulliparous women, the Framingham Risk Score was highest in menopausal age <45 years (3.97 [1.67-6.26]), but the differences were nonsignificant in menopausal age ≥55 years (0.66 [-1.38 to 2.71]).

CONCLUSIONS

Both early and late natural menopausal ages were associated with a higher cardiovascular disease risk, and the associations were stronger in those with lower parity.

The Comparison of Physical Activity, Sedentary Behavior, and Mental Health between Early Menopausal Women and Age-Matched General Middle-Aged Women

The current study is to examine the differences in physical activity (PA), sedentary behavior (SB), and mental health (i.e., stress, depression, and suicidal behaviors) between early menopausal women and age-matched general middle-aged women. Among 1348 participants in South Korea, 674 participants who experienced menopause before the age of 45 were defined as the early menopausal group, and 674 women who experienced menopause from 45 years to 55 years were classified as the general group by matching age based on early menopausal women. PA, SB, and mental health were evaluated by using the Global Physical Activity Questionnaire (GPAQ). An independent t-test was used to compare the associations of PA, SB, and mental health between the two groups. To demonstrate the predictors of early menopause, variables in the study were analyzed by multinomial logistic regression. The main findings were that moderate-to-vigorous PA (MVPA) and light PA (LPA) had significant differences between the two groups, but SB had no significant differences. In mental health, only perceived stress had significant differences in this study. The moderate level of stress in the early menopausal group was twice as high as that of the general group, and the severe level of stress was even 2.6 times higher than the general group. PA plays an essential role in mitigating the causes of mortality and the risk of various chronic diseases and improving quality of life; thus, the main findings of this study could be important to provide insights on the corresponding impact between early menopausal women and PA to encourage their healthy lifestyle. Further longitudinal studies are needed to examine the mechanisms underlying the effects of PA, SB, and mental health on early menopausal women.

Cardiometabolic health in premature ovarian insufficiency

Premature ovarian insufficiency (POI) is an increasing public health problem with a prevalence now approaching 4%. POI results in adverse effects on the skeleton and central nervous system as well as disturbances of metabolic and cardiological factors that predispose to a major increased risk of cardiovascular disease (CVD). This article reviews the effects of the premature loss of ovarian function on lipids and lipoproteins, glucose and insulin metabolism, body composition, hemostasis and blood pressure, together with effects on the development of metabolic syndrome and diabetes mellitus. The article examines the effects of POI on vascular endothelial function and inflammation that result in arterial disease, and reviews the effects of hormone replacement therapy (HRT) on these various metabolic processes and on cardiovascular outcomes. It is essential that women with POI receive hormonal treatment to help prevent the development of CVD, and that this treatment is continued at least until the normal age of menopause. It appears that HRT has a more favorable effect than the combined oral contraceptive, but larger clinical trials are needed to establish the optimal treatment. Other therapeutic measures may need to be added to correct existing metabolic abnormalities and, in particular, attention to lifestyle factors such as diet and exercise must be encouraged.

Awareness of the Causes Leading to Surgical Ablation of Ovarian Function in Premenopausal Breast Cancer-A Single-Center Analysis

Background and Objectives: Ovarian surgical ablation (OSA) in estrogen receptor-positive (ER+) breast cancer is usually performed to halt ovarian function in premenopausal patients. Since alternative pharmacological therapy exists and few studies have investigated why surgery is still performed, we aimed to analyze the reasons for the use of OSA despite the remaining controversy. Materials and Methods: Premenopausal ER+ breast cancer patients treated at a tertiary center (2005–2011) were selected, and patients with germline mutations were excluded. Results: Seventy-nine patients met the inclusion criteria. Globally, the main reasons for OSA included: continued menstruation despite hormone therapy with or without ovarian medical ablation (OMA) (34.2%), patient informed choice (31.6%), disease progression (16.5%), gynecological disease requiring surgery (13.9%), and tamoxifen intolerance/contraindication (3.8%). In women aged ≥45 years, patient choice was significantly more frequently the reason for OSA (47.4% versus 17.1% (p = 0.004)). For those aged <45 years, salvation attempts were significantly more frequent as compared to older women (26.8% versus 5.3% (p = 0.01)). In 77.8% of women undergoing OSA with menstrual cycle maintenance, surgery was performed 1–5 years after diagnosis, while surgery was performed earlier (0–3 months after diagnosis) in patients undergoing OSA as an informed choice (56.0%), as a salvation attempt (53.8%), or due to gynecological disease (63.6%). The leading reason for OSA in women previously undergoing OMA was continued menstruation (60.0%). Conclusions: This study suggests a possible failure of pharmacological ovarian suppression and reinforces the need for shared decision-making with patients when discussing treatment strategies, although validation by further studies is warranted due to our limited sample size.

Assessment of premature menopause on the sexual function and quality of life in women

INTRODUCTION

Premature Ovarian Insufficiency (POI) is characterized by ending menstruation in women under 40 years of age. It has a significant effect on women's sexuality and mental health and quality of life. This study aimed to evaluate the sexual function and quality of life of premature menopausal women.

METHODS

This study was a case-control study on 132 people (66 women with a diagnosis of POF and 66 women of reproductive age with normal ovarian function) who were matched in terms of the age, presenting to Women's Clinic in Jahrom in 2019. The WHOQOL-BREF questionnaire and the Female Sexual Function Index (FSFI) questionnaire were used to collect data. p < .05 was considered statistically significant.

RESULTS

The mean score of sexual function in premature menopausal women was 21.35 ± 4.82 and in non-menopausal women was 25.4 ± 6.61 (OR = 0.11, 95% CI = 0.04-0.28). All areas of sexual function; desires disorder (OR = 0.21 95% CI = 0.07-0.56), Arousal disorder(OR = 0.28, 95% CI = 0.08-0.93), orgasm disorder (OR = 0.36 95% CI = 0.16-0.80), lubrication disorder (OR = 0.21 95% CI= 0.05-0.78), satisfaction disorder (OR = 0.11, 95% CI = 0.04-0.28) and quality of life domains: physical health (OR = 0.4 95%CI = 0.06-0.3), mental health (OR = 0.28 95% CI = 0.06-0.1), environmental health (OR = 0.22 95%CI = 0.04-0.6) and social health (OR = 0.28 95%CI = 0.01-0.2) saw a decrease in the premature menopausal women group compared to the control group.

CONCLUSION

The results demonstrated that premature menopausal women are found to be weaker than the control group in all areas of sexual function and quality of life. Among the areas of sexual function, such as libido, arousal, satisfaction, and pain have the most impact on quality of life. Therefore, based on the results from improving sexual function, this issue can improve the quality of life.

Cardiovascular health after menopause transition, pregnancy disorders, and other gynaecologic conditions: a consensus document from European cardiologists, gynaecologists, and endocrinologists

Women undergo important changes in sex hormones throughout their lifetime that can impact cardiovascular disease risk. Whereas the traditional cardiovascular risk factors dominate in older age, there are several female-specific risk factors and inflammatory risk variables that influence a woman's risk at younger and middle age. Hypertensive pregnancy disorders and gestational diabetes are associated with a higher risk in younger women. Menopause transition has an additional adverse effect to ageing that may demand specific attention to ensure optimal cardiovascular risk profile and quality of life. In this position paper, we provide an update of gynaecological and obstetric conditions that interact with cardiovascular risk in women. Practice points for clinical use are given according to the latest standards from various related disciplines (Figure 1).

Premature and Early Menopause in Relation to Cardiovascular Disease

Postmenopausal women have an increased risk for cardiovascular diseases. It has been postulated that the loss of ovarian function and subsequent deficiency of endogenous estrogens after menopause contributes to this elevated risk of cardiovascular disease in postmenopausal women. Compared with woman entering menopause at the mean age of 51 years, in women with early menopause or premature ovarian insufficiency the risk for cardiovascular disease is even greater. These women lack the cardioprotective effect of endogenous estrogens for many more years than do women entering natural menopause. The majority of data assessing the risk of cardiovascular disease in relation to age at menopause and specifically premature menopause are derived from large epidemiological cohort studies. In addition, observations in women undergoing bilateral oophorectomy at an early age provide convincing evidence regarding association between early menopause or POI and the development of cardiovascular events and mortality. Moreover, genetic variants associated with earlier age at menopause have also been found to increase the risk of cardiovascular events in women. It has been substantiated that hormone replacement therapy (HRT) decreases the risk for ischemic heart disease and eliminates the increased cardiovascular disease mortality. It is therefore crucial to start HRT as soon as possible, particularly in women with premature ovarian insufficiency.

Long-Term Morbidity and Health After Early Menopause Due to Oophorectomy in Women at Increased Risk of Ovarian Cancer: Protocol for a Nationwide Cross-Sectional Study With Prospective Follow-Up (HARMOny Study)

Background

BRCA1/2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) at 35 to 45 years of age. RRSO substantially decreases ovarian cancer risk, but at the cost of immediate menopause. Knowledge about the potential adverse effects of premenopausal RRSO, such as increased risk of cardiovascular disease, osteoporosis, cognitive dysfunction, and reduced health-related quality of life (HRQoL), is limited.

Objective

The aim of this study is to assess the long-term health effects of premenopausal RRSO on cardiovascular disease, bone health, cognitive functioning, urological complaints, sexual functioning, and HRQoL in women with high familial risk of breast or ovarian cancer.

Methods

We will conduct a multicenter cross-sectional study with prospective follow-up, nested in a nationwide cohort of women at high familial risk of breast or ovarian cancer. A total of 500 women who have undergone RRSO before 45 years of age, with a follow-up period of at least 10 years, will be compared with 250 women (frequency matched on current age) who have not undergone RRSO or who have undergone RRSO at over 55 years of age. Participants will complete an online questionnaire on lifestyle, medical history, cardiovascular risk factors, osteoporosis, cognitive function, urological complaints, and HRQoL. A full cardiovascular assessment and assessment of bone mineral density will be performed. Blood samples will be obtained for marker analysis. Cognitive functioning will be assessed objectively with an online neuropsychological test battery.

Results

This study was approved by the institutional review board in July 2018. In February 2019, we included our first participant. As of November 2020, we had enrolled 364 participants in our study.

Conclusions

Knowledge from this study will contribute to counseling women with a high familial risk of breast/ovarian cancer about the long-term health effects of premenopausal RRSO. The results can also be used to offer health recommendations after RRSO.

Mitochondrial Dysfunction in Obesity and Reproduction

Mounting evidence suggests a role for mitochondrial dysfunction in the pathogenesis of many diseases, including type 2 diabetes, aging, and ovarian failure. Because of the central role of mitochondria in energy production, heme biosynthesis, calcium buffering, steroidogenesis, and apoptosis signaling within cells, understanding the molecular mechanisms behind mitochondrial dysregulation and its potential implications in disease is critical. This review will take a journey through the past and summarize what is known about mitochondrial dysfunction in various disorders, focusing on metabolic alterations and reproductive abnormalities. Evidence is presented from studies in different human populations, and rodents with genetic manipulations of pathways known to affect mitochondrial function.

Current Understanding of the Etiology, Symptomatology, and Treatment Options in Premature Ovarian Insufficiency (POI)

Premature ovarian insufficiency (POI) occurs in at least 1% of all women and causes life-long health problems and psychological stress. Infertility caused by POI used to be considered absolute, with infertility treatment having little or no value. Generally, it has been thought that medicine can provide little service to these patients. The etiology of POI has been found to be genetic, chromosomal, and autoimmune. In addition, the increasing numbers of cancer survivors are candidates for iatrogenic POI, along with patients who have undergone ovarian surgery, especially laparoscopic surgery. Over 50 genes are known to be causally related to POI, and the disease course of some cases has been clarified, but in most cases, the genetic background remains unexplained, suggesting that more genes associated with the etiology of POI need to be discovered. Thus, in most cases, the genetic background of POI has not been clarified. Monosomy X is well known to manifest as Turner's syndrome and is associated with primary amenorrhea, but recent studies have shown that some women with numerical abnormalities of the X chromosome can have spontaneous menstruation up to their twenties and thirties, and some even conceive. Hormone replacement therapy (HRT) is recommended for women with POI from many perspectives. It alleviates vasomotor and genitourinary symptoms and prevents bone loss and cardiovascular disease. POI has been reported to reduce quality of life and life expectancy, and HRT may help improve both. Most of the problems that may occur with HRT in postmenopausal women do not apply to women with POI; thus, in POI, HRT should be considered physiological replacement of estrogen (+progesterone). This review describes some new approaches to infertility treatment in POI patients that may lead to new treatments for POI, along with the development of more sensitive markers of secondary/preantral follicles and genetic diagnosis.

A current perspective into young female sex hormone replacement: a review

INTRODUCTION

Hormone replacement in females with hypogonadism is advocated to address the various clinical aspects of estrogen deficiency.

AREAS COVERED

This article focuses on hormone replacement in young females with hypogonadism, including a rationale as to why hormone replacement in such patients differs from treatment in postmenopausal females, a summary of symptoms encountered by females with hypogonadism and a comprehensive discussion of the various treatment options available, specifically focusing on the latest advances in the subject. A Medline search was conducted using different combinations of relevant keywords, giving preference to recent publications.

EXPERT OPINION

Whilst traditionally oral contraceptive pills (containing ethynyl estradiol) were commonly used as a form of hormone replacement, it is now increasingly recognized that this is not the optimal treatment option. Physiological hormone replacement with transdermal estradiol is found to be superior. Evidence suggests that micronized progesterone may be associated with fewer side effects, although its effect on endometrial protection is not yet proven. Synthetic progestins confer varying degrees of androgenic and thromboembolic properties which should be kept in mind when prescribing individualized treatment. Further studies in different sub-cohorts of female patients with hypogonadism might help address the specific needs of individual patients.

Operative management of pediatric ovarian tumors and the challenge of fertility-preservation: Results from the UK CCLG Surgeons Cancer Group Nationwide Study

BACKGROUND

Ovarian tumors in the pediatric age group are rare. A significant number of children with ovarian mass lesions present "out of hours "as surgical emergencies, and surgical management does not always involve a surgical oncologist. This multicenter study reports how the mode of clinical presentation may influence (i) operation (conventional open vs minimally invasive surgery (MIS)) and (ii) examines if young females presenting as surgical emergency(s) are more likely to undergo total oophorectomy or ovarian sparing surgery.

METHODS

Retrospective multicenter study amongst UK pediatric surgical oncology centers. Females <16 years with diagnosis of ovarian tumor from 2006 to 2016 were included. Functional/neonatal ovarian cysts were excluded.

RESULTS

Three hundred ten patients with ovarian tumors treated at 12 surgical oncology centers were identified. Mean age at surgery was 11 years [IQR 8-14]. Most common diagnosis were mature teratoma (57%, 177 cases), immature teratoma (10.9%, 34 cases) and cystadenoma (12%, 36 cases). Seventy percent (217) of cases were performed as open procedures. Thirty percent (94) of children underwent MIS. Tumors were significantly smaller in children who underwent MIS. Median tumor size in the laparoscopic group was 6 cm compared to 11 cm in the open group (p < 0.00001). Children who underwent MIS were significantly more likely to have ovary sparing surgery.

CONCLUSION

This UK nationwide study demonstrates that ovary-sparing surgery and minimally invasive surgery are still infrequently deployed by pediatric surgeons in the UK. Patients with smaller tumors were more likely to undergo MIS, and more frequently underwent ovary-sparing surgery. In view of the implications on fertility and hormonal health caused by unilateral oophorectomy, it is time to review this current practise and agree consensus guidelines to reduce rates of unnecessary oophorectomy.

LEVEL OF EVIDENCE STATEMENT

This is a level II evidence study. It is a retrospective multicentre collaborative study, which summarizes data from a national cohort of children.
