Abstract INTRODUCTION Premenopausal bilateral oophorectomy (PBO) before the age of 46 years is associated with an increased risk of dementia. We investigated the long‐term effects of PBO performed before age 50 years on amyloid beta (Aβ), tau, and neurodegeneration imaging biomarkers of Alzheimer's disease (AD). METHODS Mayo Clinic Cohort Study of Oophorectomy and Aging‐2 participants were divided into early PBO (< 46 years; n = 61), and late PBO (46–49 years; n = 51) groups and were compared to referent women who did not undergo PBO ( n = 119). RESULTS Early PBO was associated with thinner entorhinal cortex ( p = 0.014), higher tau load at higher levels of Aβ load ( Pp = 0.005), higher Aβ load ( p = 0.026), and smaller temporal lobe cortical thickness ( p = 0.022), only at older ages compared to the referent group. DISCUSSION PBO before the age of 46 years is associated with entorhinal cortex thinning, elevated tau at higher Aβ levels, along with an AD‐like pattern of atrophy at older ages. CLINICAL TRIALS REGISTRATION NCT03821857 sex‐specific effects of endocrine disruption on aging and AD. Highlights Premenopausal bilateral oophorectomy (PBO) before the ages of 46 (early PBO) years and ages 46 to 49 (late PBO) years was studied. Early PBO was associated with reduced entorhinal cortex thickness later in life. Early PBO was associated with greater amyloid beta (Aβ) load at older ages. Early PBO was associated with greater Alzheimer's disease pattern of atrophy at older ages. Early PBO was associated with higher tau load at higher Aβ levels.

Abstract Objectives The aims of the study were to identify conditions diagnosed in at least 10% of midlife women living in the US upper midwest and to assess prevalence by age, race, ethnicity, and sociodemographic status. Methods The Rochester Epidemiology Project was used to conduct a cross-sectional prevalence study of 86,946 women between 40 and 59 years residing in a 27-county region of the United States on January 1, 2020. Diagnostic billing codes were extracted and grouped into broader condition categories using the Clinical Classification System Refined. The prevalence of 424 conditions was calculated by age, race, ethnicity, and area deprivation index quartiles. Logistic regression was used to examine associations between participant characteristics and conditions that affected 10% or more of the study population. Results Twenty-eight conditions affected ≥10% of women, and eight conditions increased by ≥45% between the ages of 40 and 59 (disorders of lipid metabolism, hypertension, sleep/wake disorders, thyroid disorders, esophageal disorders, osteoarthritis, tendon and synovial disorders, and menopausal disorders; all test for trend P < 0.01). Black women had a significantly higher prevalence of hypertension and esophageal disorders at all ages (adjusted P values <0.05). Women living in more deprived areas had a significantly higher prevalence of hyperlipidemia, hypertension, sleep/wake disorders, and esophageal disorders (adjusted P values <0.05). Women living in less deprived areas had a significantly higher prevalence of thyroid disorders at age 40 to 44 and menopausal disorders at ages 50 to 59 (adjusted P values <0.05). Conclusions These data suggest that additional attention should focus on Black women and women with a lower socioeconomic status to ensure that common midlife conditions are diagnosed and treated.

Abstract STUDY QUESTION How should premature/primary ovarian insufficiency (POI) be diagnosed and managed based on the best available evidence from published literature? SUMMARY ANSWER The current guideline provides 145 recommendations on symptoms, diagnosis, causation, sequelae, and treatment of POI. WHAT IS KNOWN ALREADY Premature ovarian insufficiency (POI) presents a significant challenge to women’s health, with far-reaching implications, both physically and emotionally. The potential implications include adverse effects on quality of life; fertility; and bone, cardiovascular, and cognitive health. Although hormone therapy (HT) can mitigate some of these effects, many questions still remain regarding the optimal management of POI. STUDY DESIGN, SIZE, DURATION The guideline was developed according to the structured methodology for development of ESHRE guidelines. Key questions were determined by a group of experts and informed by a scoping survey of women and health care professionals. Literature searches and assessments were then performed. Papers published up to 30 January 2024 and written in English were included in the guideline. An integrity review was conducted for the randomized controlled trials (RCTs) on POI included in the guideline. PARTICIPANTS/MATERIALS, SETTING, METHODS Based on the collected evidence, recommendations were formulated and discussed within the guideline development group until consensus was reached. Women with lived experience of POI informed the recommendations in general, and particularly on those on provision of care. A stakeholder review was organized after finalization of the draft. The final version was approved by the guideline development group and the ESHRE Executive Committee. MAIN RESULTS AND THE ROLE OF CHANCE New data indicate a higher prevalence of POI, 3.5%, than was previously thought. This guideline aims to help health care professionals to apply best practice care for women with POI. The recent update of the POI guideline covers 40 clinical questions on diagnosis of the condition, the different sequelae, including bone, cardiovascular, neurological and sexual function, fertility and general well-being, and treatment options, including HT. The list of clinical questions was expanded from the previous iteration of the guideline (2015) based on the scoping survey and appreciation of emerging knowledge of POI. Questions were added on the role of anti-Müllerian hormone (AMH) in the diagnosis of POI, fertility preservation, muscle health, and specific considerations for HT in iatrogenic POI. Additionally, the topic on complementary treatments was extended with specific focus on non-hormonal treatments and lifestyle management options. Significant changes from the previous 2015 guideline include the recommendations that only one elevated FSH &gt;25 IU is required for diagnosis of POI, and guidance that AMH testing, repeat FSH measurement, and/or AMH may be required where there is diagnostic uncertainty. Recommendations were also updated regarding genetic testing, estrogen doses and regimens, use of the combined oral contraceptive and testosterone therapy. Women with lived experience of POI informed the recommendations on provision of care. LIMITATIONS, REASONS FOR CAUTION The guideline describes different management options, but it must be acknowledged that for most of these options, supporting evidence is limited for POI. WIDER IMPLICATIONS OF THE FINDINGS The guideline provides health care professionals with clear advice on best practice in POI care, based on the best evidence currently available. In addition, a list of research recommendations is provided to guide further studies in POI.

Abstract Premature ovarian insufficiency (POI) presents a significant challenge to women's health, with significant implications both physically and emotionally. Despite its life-altering impact, there remain substantial unknowns in the causes this condition and how to optimally manage its various sequelae While such unknows provide direction for future research, they also underscore the need for clinical guidance. In 2015, under the auspices of ESHRE, a group of experts evaluated the existing best evidence and published the first European guideline on the management of premature ovarian insufficiency. The update of this Guideline was performed in an international collaboration of experts representing American Society for Reproductive Medicine (ASRM), International Menopause Society (IMS), and the Centre for Research Excellence in Women’s Health in Reproductive Life (CRE WHiRL). The recent update of the POI guideline covers 40 clinical questions on diagnosis of the condition, the different sequelae, including musculoskeletal health, cardiovascular health, neurological health, sexual function and general well being, and treatment options, including hormone therapy. The list of clinical questions was expanded from the questions included in the guideline from 2015. Based on a scoping survey and appreciation of emerging knowledge of POI, questions were added on the role of AMH in the diagnosis of POI, fertility preservation, muscle health, and specific considerations for hormone treatment in iatrogenic POI. Additionally, the topic on complementary treatments was extended with specific focus on non-hormonal treatments and lifestyle management options. The draft guideline published for stakeholder review includes a total of 142 recommendations. One third of these recommendations were formulated as good practice points. Of the evidence-based recommendations, almost 80% were formulated as strong recommendations, even if the evidence base for most evidence-based recommendations was limited to observational data (level very low or low), supporting a call for future research. The guideline group hope that the new POI Guideline will improve the clinical management of this devastating condition.

AbstractINTRODUCTIONPremenopausal bilateral oophorectomy (PBO) is associated with later‐life cognition, but the underlying brain changes remain unclear. We assessed the impact of PBO and PBO age on white matter integrity.METHODSFemale participants with regional diffusion tensor imaging (DTI) metrics of fractional anisotropy (FA) and mean diffusivity (MD) were included (22 with PBO < 40 years; 43 with PBO 40‐45 years; 39 with PBO 46‐49 years; 907 referents without PBO < 50 years). Linear regression models adjusted for age and apolipoprotein E (APOE) genotype.RESULTSFemales with PBO < 40 years, compared to referents, had lower FA and higher MD in the anterior corona radiata, genu of the corpus collosum, inferior fronto‐occipital fasciculus, superior occipital, and superior temporal white matter. Females who underwent PBO between 45 and 49 also had some changes in white matter integrity.DISCUSSIONFemales who underwent PBO < 40 years had reduced white matter integrity across multiple regions in later‐life. These results are important for females considering PBO for noncancerous conditions.Highlights Females with premenopausal bilateral oophorectomy (PBO) < 40 years had lower FA versus referents. Females with PBO < 40 years had higher MD in many regions versus referents. Adjusting for estrogen replacement therapy use did not attenuate results. Females with PBO 45‐49 years also had some white matter changes versus referents.

AbstractINTRODUCTIONFemale‐specific reproductive factors and exogeneous estrogen use are associated with cognition in later life. However, the underlying mechanisms are not understood. The present study aimed to investigate the effect of reproductive factors on neuroimaging biomarkers of Alzheimer's disease (AD) and cerebrovascular pathologies.METHODSWe evaluated 389 females (median age of 71.7 years) enrolled in the Mayo Clinic Study of Aging with reproductive history data and longitudinal magnetic resonance imaging (MRI) scans. We used linear mixed effect models to examine the associations between reproductive factors and changes in neuroimaging measures.RESULTSEver hormonal contraception (HC) use was longitudinally associated with higher fractional anisotropy across the corpus callosum, lower white matter hyperintensity (WMH) volume, and greater cortical thickness in an AD meta‐region of interest (ROI). The initiation of menopausal hormone therapy (MHT) > 5 years post menopause was associated with higher WMH volume.DISCUSSIONHC use and initiation of MHT >5 years post menopause were generally associated with neuroimaging biomarkers of cerebrovascular pathologies.Highlights Hormonal contraception use was associated with better brain white matter (WM) integrity. Initiation of menopausal hormone therapy >5 years post menopause was associated with worsening brain WM integrity. Hormonal contraception use was associated with greater cortical thickness. Ages at menarche and menopause and number of pregnancies were not associated with imaging measures. There were few associations between reproductive factors or exogenous estrogens and amyloid or tau PET.

Abstract Background Body composition can be accurately quantified from abdominal computed tomography (CT) exams and is a predictor for the development of aging-related conditions and for mortality. However, reference ranges for CT-derived body composition measures of obesity, sarcopenia, and bone loss have yet to be defined in the general population. Methods We identified a population-representative sample of 4 900 persons aged 20 to 89 years who underwent an abdominal CT exam from 2010 to 2020. The sample was constructed using propensity score matching an age and sex stratified sample of persons residing in the 27-county region of Southern Minnesota and Western Wisconsin. The matching included race, ethnicity, education level, region of residence, and the presence of 20 chronic conditions. We used a validated deep learning based algorithm to calculate subcutaneous adipose tissue area, visceral adipose tissue area, skeletal muscle area, skeletal muscle density, vertebral bone area, and vertebral bone density from a CT abdominal section. Results We report CT-based body composition reference ranges on 4 649 persons representative of our geographic region. Older age was associated with a decrease in skeletal muscle area and density, and an increase in visceral adiposity. All chronic conditions were associated with a statistically significant difference in at least one body composition biomarker. The presence of a chronic condition was generally associated with greater subcutaneous and visceral adiposity, and lower muscle density and vertebrae bone density. Conclusions We report reference ranges for CT-based body composition biomarkers in a population-representative cohort of 4 649 persons by age, sex, body mass index, and chronic conditions.

AbstractBackgroundSeveral studies suggest that premenopausal bilateral oophorectomy (PBO) is associated with an increased risk of cognitive impairment and dementia; however, the underlying brain changes are not well understood. Animal studies suggest that long‐term ovarian hormone deprivation in rats is associated with reduced white matter integrity, but few studies have been conducted among women. We assessed the impact of age at PBO before age 50 years on white matter integrity in a community‐based cohort of older women.MethodParticipants included 1,011 women enrolled in the Mayo Clinic Study on Aging (MCSA; 22 with PBO<40 years; 43 with PBO 40‐45 years; 39 with PBO 46‐49 years and 907 referent women). MCSA is a population‐based study of aging in Olmsted County, MN. PBO was abstracted from the medical records. Regional DTI metrics of fractional anisotropy (FA) and mean diffusivity (MD) were investigated using the Johns Hopkins University Atlas. Linear regression was used to examine the association between PBO age group and z‐scores of either FA or MD after adjusting for age at imaging and APOE.ResultThere were no differences in age at study visit (median = 72 years), education, APOE E4 frequency, or vascular comorbidities between the 3 groups of women with a history of PBO or referent women. Women with PBO<40 years, compared to referent women, had lower FA and higher MD in the anterior corona radiata, genu of the corpus collosum, inferior fronto‐occipital fasciculus, superior occipital, and superior temporal white matter. Women with PBO<40 years also had lower inferior frontal white matter FA and higher posterior thalamic radiation MD. Women who underwent PBO between 40‐44 years or 45‐49 generally did not have significant changes in white matter integrity compared to referent women.ConclusionWomen who underwent premenopausal bilateral oophorectomy prior to the age of 40 years had reduced white matter integrity across multiple regions in later‐life. These results are important for the education of women at a low risk for ovarian cancer who are considering PBO for benign conditions.
