Abstract
OBJECTIVE To evaluate the effect of risk-reducing salpingo-oophorectomy (RRSO) on change in bone mineral density (BMD) in women aged 34-50 years with pathogenic variants in BRCA1 or BRCA2 (BRCA1/2). METHODS The PROSper (Prospective Research of Outcomes after Salpingo-oophorectomy) study is a prospective cohort of women aged 34-50 years with BRCA1 or two germline pathogenic variants that compares health outcomes after RRSO to a non-RRSO control group with ovarian conservation. Women aged 34-50 years, who were planning either RRSO or ovarian conservation, were enrolled for 3 years of follow-up. Spine and total hip BMD were measured by dual-energy X-ray absorptiometry (DXA) scans obtained at baseline before RRSO or at the time of enrollment for the non-RRSO group, and then at 1 and 3 years of study follow-up. Differences in BMD between the RRSO and non-RRSO groups, as well as the association between hormone use and BMD, were determined by using mixed effects multivariable linear regression models. RESULTS Of 100 PROSper participants, 91 obtained DXA scans (RRSO group: 40; non-RRSO group: 51). Overall, total spine, and hip BMD decreased significantly from baseline to 12 months after RRSO (estimated percent change -3.78%, 95% CI -6.13% to -1.43% for total spine; -2.96%, 95% CI -4.79% to -1.14% for total hip) and at 36 months (estimated percent change -5.71%, 95% CI -8.64% to -2.77% for total spine; -5.19%, 95% CI -7.50% to -2.87% for total hip. In contrast, total spine and hip BMD were not significantly different from baseline for the non-RRSO group. The differences in mean percent change in BMD from baseline between the RRSO and non-RRSO groups were statistically significant at both 12 and 36 months for spine BMD (12-month difference -4.49%, 95% CI -7.67% to -1.31%; 36-month difference -7.06%, 95% CI -11.01% to -3.11%) and at 36 months for total hip BMD (12-month difference -1.83%, 95% CI -4.23% to 0.56%; 36-month difference -5.14%, 95% CI -8.11% to -2.16%). Across the study periods, hormone use was associated with significantly less bone loss at both the spine and hip within the RRSO group compared with no hormone use (P<.001 at both 12 months and 36 months) but did not completely prevent bone loss (estimated percent change from baseline at 36 months -2.79%, 95% CI -5.08% to -0.51% for total spine BMD; -3.93%, 95% CI -7.27% to -0.59% for total hip BMD). CONCLUSION Women with pathogenic variants in BRCA1/2 who undergo RRSO before the age of 50 years have greater bone loss after surgery that is clinically significant when compared with those who retain their ovaries. Hormone use mitigates, but does not eliminate, bone loss after RRSO. These results suggest that women who undergo RRSO may benefit from routine screening for BMD changes to identify opportunities for prevention and treatment of bone loss.

Abstract
OBJECTIVES Studies investigating the safety of hormone replacement therapy in cervical cancer have predominantly included patients with squamous disease. Pathological studies have identified estrogen receptor positivity in cervical adenocarcinomas. A recent small case-control study suggested a trend towards reduced survival with hormone replacement therapy in cervical adenocarcinomas. Our objective was to determine if hormone replacement therapy use in patients treated for cervical adenocarcinomas is detrimental to survival. STUDY DESIGN A retrospective review of all women under the age of 50 with stage 1B-2B cervical adenocarcinomas diagnosed between 1 November 2000 and 24 September 2019. Women were categorised into three groups: ovaries conserved (OVCON); or iatrogenic menopause with (IM-HRT) or without (IM-NOHRT) hormone replacement therapy. Hormone replacement therapy use was defined on an intention to treat basis. Statistical analysis was performed using Kaplan-Meier and Cox proportional hazards methods. MAIN OUTCOME MEASURES Overall (OS), disease specific (DSS) and progression free (PFS) survival. RESULTS A total of 58 women (mean age 38.5 ± 6.6) were included in the study of whom 25 (43.1%) had OVCON, 20 (34.4%) had IM-HRT and 13 (22.4%) had IM-NOHRT. No menopause-associated deaths occurred. Although five-year DSS was 73% in IM-NOHRT compared to 95% in IM-HRT and 95% in OVCON, these differences were not statistically significant. Five-year PFS was 68% in IM-NOHRT compared to 90% in IM-HRT and 81% in OVCON but again, these differences were not statistically significant. CONCLUSION In this small study, hormone replacement therapy does not appear to be detrimental to survival in cervical adenocarcinomas. There is a trend towards improved survival with hormone replacement therapy. Larger studies are required to substantiate these findings.

Abstract
Premature ovarian insufficiency (POI) - the loss of ovarian function before the age of 40 years, a decade before natural menopause - is a life-changing diagnosis for women. POI causes significant short-term and long-term morbidity related to estrogen deficiency. The condition is managed by providing exogenous estrogen replacement, usually as the oral contraceptive pill or hormone therapy. These preparations have different estrogen formulations and may have differing benefits and risks. At present, there are no robust data to inform clinical recommendations and women's decision-making about treatment that they may be taking for many years. The POISE study (Premature Ovarian Insufficiency Study of Effectiveness of hormonal therapy) has been designed to determine whether hormone therapy is superior to combined oral contraceptives on important clinical outcomes and patient-reported symptoms, based on the hypothesis that hormone therapy provides more physiological continuous hormone supplementation with natural estrogens. The study is an open and pragmatic, parallel, randomized controlled trial. The primary outcome is absolute bone mineral density assessed by dual-energy X-ray absorptiometry of the lumbar spine after 2 years of treatment. The study will also investigate cardiovascular markers, symptom relief and acceptability of treatment, and will continue to collect long-term data on fractures and cardiovascular events. Results will inform future guidance on management of POI.

Abstract
Accelerated bone loss and muscle loss coexist in women with premature ovarian insufficiency (POI), but there are significant gaps in our understanding of musculoskeletal health in POI. This review describes estrogen signaling in bone and its role in skeletal health and disease. Possible mechanisms contributing to bone loss in different forms of POI and current evidence regarding the utility of available diagnostic tests and therapeutic options are also discussed. A literature review from January 2000 to March 2020 was conducted to identify relevant studies. Women with POI experience significant deterioration in musculoskeletal health due to the loss of protective effects of estrogen. In bone, loss of bone mineral density (BMD) and compromised bone quality result in increased fracture risk; however, tools to assess bone quality such as trabecular bone score (TBS) need to be validated in this population. Timely initiation of HRT is recommended to minimize the deleterious effects of estrogen deficiency on bone in the absence of contraindications; however, the ideal estrogen replacement regimen remains unknown. POI is associated with compromised bone health, regardless of the etiology. Ongoing research is warranted to refine our management strategies to preserve bone health in women with POI.

Abstract
UNLABELLED Prophylactic oophorectomy is recommended for women at high risk for ovarian cancer, but the associated impact on bone health is of clinical concern. This prospective, controlled study demonstrated substantial loss of bone density and bone strength following surgical menopause. Postoperative hormone therapy alleviated, but not fully prevented, spinal bone loss. INTRODUCTION This prospective study investigated bone health in women following premenopausal oophorectomy. METHODS Dual-energy x-ray absorptiometry (DXA), peripheral quantitative computed tomography (pQCT), and pQCT-based finite element analysis (pQCT-FEA) were used to assess bone health between systemic hormone therapy (HT) users and non-users after premenopausal risk-reducing bilateral salpingo-oophorectomy (RRBSO) compared with premenopausal controls over 24-month follow-up. RESULTS Mean age was 42.4 ± 2.6 years (n = 30) for the surgery group and 40.2 ± 6.3 years for controls (n = 42), and baseline bone measures were similar between groups. Compromised bone variables were observed at 24 months after RRBSO, among which areal bone mineral density (aBMD) at the lumbar spine, tibial volumetric cortical density (Crt vBMD), and tibial bending stiffness (kbend) had decreased by 4.7%, 1.0%, and 12.1%, respectively (all p < 0.01). In non-HT users, significant losses in lumbar spine (5.8%), total hip (5.2%), femoral neck (6.0%) aBMD, tibial Crt vBMD (2.3%), and kbend (14.8%) were observed at 24 months (all p < 0.01). HT prevented losses in kbend, tibial Crt vBMD, and aBMD, except for modest 2.3% loss at the lumbar spine (p = 0.01). CONCLUSION This prospective, controlled study of bone health following RRBSO or premenopausal oophorectomy demonstrated substantial loss of bone density and bone strength following RRBSO. HT prevented loss of bone density and bone stiffness, although there was still a modest decrease in lumbar spine aBMD in HT users. These findings may inform decision-making about RRBSO and clinical management following premenopausal oophorectomy.

Abstract
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.

Abstract
AIM This study investigated the risk of osteoporosis or bone fractures (vertebrae, hip and others) in hysterectomized women in Taiwan. MATERIALS AND METHODS This is a retrospective population-based cohort study from 2000 to 2013. Women aged ≥30 years who underwent hysterectomy between 2000 and 2012 were included in this study. The comparison group was randomly selected from the database with a 1:4 matching with age and index year. Incidence rate and hazard ratios of osteoporosis and bone fracture between hysterectomized women and the comparison group were calculated. Cox proportional hazard regressions were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS We identified 9,189 hysterectomized women and 33,942 age-matched women without a hysterectomy. All women were followed for a median time of about 7 years. The adjusted hazard ratio (aHR) of subsequent osteoporosis or bone fracture was higher in the hysterectomy women (2.26, 95% confidence interval [CI] = 2.09-2.44) than in the comparison group. In the subgroup analysis, oophorectomy and estrogen therapy increase the risk of osteoporosis or fracture in both groups. Regarding the fracture site, the aHR of vertebral fracture (4.92, 95% CI = 3.78-6.40) was higher in the hysterectomized women than in the comparison group. As follow-up time increasing, the aHR of vertebral fracture in hysterectomized women were 4.33 (95% CI = 2.99-6.28), 3.89 (95% CI = 2.60-5.82) and 5.42 (95% CI = 2.66-11.01) for <5, 5-9 and ≥9 years of follow-up, respectively. CONCLUSIONS In conclusion, we found that hysterectomized women might be associated with increased risks of developing osteoporosis or bone fracture.

Abstract
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.

Abstract
Background The changes in bone homeostasis observed during pregnancy and lactation could result in alterations in the rate of orthodontic tooth movement, but research in human subjects presents significant ethical and practical limitations. Our aim was to compare the amount of orthodontic tooth movement between pregnant/lactating or not animals. Methods We searched without restrictions 8 databases and performed hand searching until July 2019 (PubMed, Central, Cochrane Database of Systematic Reviews, SCOPUS, Web of Science, Arab World Research Source, ClinicalTrials.gov, ProQuest Dissertations and Theses Global). We searched for studies comparing quantitatively the amount of orthodontic tooth movement between pregnant/lactating or not animals. Following retrieval and selection of studies, the collection of related data was performed and the risk of bias was assessed using the SYRCLE’s Risk of Bias Tool. Exploratory synthesis was carried out using the random effects model. Results Four studies were finally identified raising no specific concerns regarding bias. One study showed that lactation increased the rate of tooth movement by 50 % [p < 0.05]. Although an overall increase was noted in the pregnancy group as well, it did not reach statistical significance [3 studies, Weighted Mean Difference: 0.10; 95% Confidence Interval: − 0.04 - 0.24; p = 0.165]. Conclusions The metabolic changes occurring during pregnancy and lactation may have an impact on the rate of tooth movement in animals. Although these animal experimental results should be approached cautiously, it could be safe practice to consider the impact of these physiological changes in the clinical setting.

Abstract
CONTEXT The long-term effects of female hormone replacement therapy (HRT) in Turner syndrome (TS) are unknown. OBJECTIVE To examine morbidity, mortality and medicinal use in TS and the impact of HRT in 45,X women. DESIGN AND SETTING National cohort study, following all TS individuals ever diagnosed in Denmark from 1977 to 2014. PATIENTS AND METHODS In the Danish Cytogenetic Central Registry, we identified 1156 females diagnosed with TS from 1960 to 2014, and, subsequently, Statistics Denmark randomly identified 115 577 age-matched female controls. TS women and their matched controls were linked with person-level data from the National Patient Registry and the Medication Statistics Registry, and they were compared concerning mortality, hospitalizations, and medical prescriptions. Among 329 45,X women, 44 had never been HRT treated, and 285 had been treated at some point. HRT treated women were compared with untreated concerning mortality, hospitalizations, and medical prescriptions. RESULTS Endocrine and cardiovascular mortality and morbidity were significantly increased in TS compared with the matched controls. Comparing HRT treated with nontreated 45,X women, we found a similar mortality (hazard ratio 0.83, 95% confidence interval 0.38-1.79). Among the HRT-treated 45,X women, we found a significantly lower use of antihypertensives, antidiabetics, and thyroid hormones and significantly reduced hospitalization rates for stroke and osteoporotic fractures. CONCLUSION Women with TS have an increased overall mortality and morbidity. HRT seems to have a beneficial effect on endocrine conditions, hypertension, and stroke in women with 45,X karyotype, with no clear impact on mortality.

Abstract
STUDY DESIGN Prospective feasibility study on consecutive patients. OBJECTIVE The aim of this study was to investigate the ability of regional BMD around the pedicle screw to predict the screw fixation. SUMMARY OF BACKGROUND DATA Pedicle screw fixation is the gold standard technique for spinal fusion. Despite the advantage of biomechanical stability, screw loosening is a common complication. In previous studies, pullout strength and screw insertional torque were correlated, and most importantly, affected by bone mineral density (BMD). Although the density and structure of the vertebral body are not homogeneous, no study has yet evaluated the relationship between screw insertional torque and regional BMD around the pedicle screw in vivo. METHODS Consecutive 50 patients, scheduled for transpedicular fixation, were evaluated preoperatively for BMD measured by dual-energy absorptiometry (DXA) and quantitative computed tomography (QCT). Regional volumetric BMD around the pedicle screw (PS-vBMD) using the novel QCT technique was also evaluated. Among all patients, 190 screws (diameter, 7.5 to 8.5 mm; length, 40 to 45 mm, inserted from L1 to L5) were eligible for this study and were analyzed to identify factors contributing to insertional torque. The following factors were investigated: age, body mass index, laboratory data, pedicle diameter, screw diameter, screw length, and 5 types of bone mineral density measures [DXA: spine-areal BMD (aBMD), total hip-aBMD, femoral neck-aBMD, QCT: central-vBMD, PS-vBMD]. RESULTS Insertional torque was significantly correlated with each BMD measurement and strongest with PS-vBMD (r=0.61, P<0.001). Multiple regression analysis showed PS-vBMD was most strongly correlated with screw insertional torque (stdβ=0.494; P<0.001). A model containing the following 5 predictors was significantly associated with screw insertional torque: age, pedicle diameter, screw diameter, screw length, and PS-vBMD. CONCLUSIONS The preoperative measurement of PS-vBMD was technically feasible and reliably predictive of screw insertional torque during transpedicular fixation in a clinical setting.

Abstract
Estradiol (E2) is women's dominant 'bone hormone' since it is essential for development of adolescent peak bone mineral density (BMD) and physiological levels prevent the rapid (3-week) bone resorption that causes most adult BMD loss. However, deceasing E2 levels trigger bone resorption/loss. Progesterone (P4) is E2's physiological partner, collaborating with E2 in every cell/tissue; its bone 'job' is to increase P4-receptor-mediated, slow (3-4 months) osteoblastic new bone formation. When menstrual cycles are normal length and normally ovulatory, E2 and P4 are balanced and BMD is stable. However, clinically normal cycles commonly have ovulatory disturbances (anovulation, short luteal phases) and low P4 levels; these are more frequent in teen and perimenopausal women and increased by everyday stressors: energy insufficiency, emotional/social/economic threats and illness. Meta-analysis shows that almost 1%/year spinal BMD loss occurs in those with greater than median (∼31%) of ovulatory disturbed cycles. Prevention of osteoporosis and fragility fractures requires the reversal of stressors, detection and treatment of teen-to-perimenopausal recurrent cycle/ovulatory disturbances with cyclic oral micronized progesterone. Low 'Peak Perimenopausal BMD' is likely the primary risk for fragility fractures in later life. Progesterone plus estradiol or other antiresorptive therapies adds 0.68%/year and may be a highly effective osteoporosis treatment. Randomized controlled trials are still needed to confirm progesterone's important role in women's bone formation.

Abstract
BACKGROUND Premature ovarian insufficiency (POI), often and misleadingly referred to as ‘premature menopause’, is defined as a loss of ovarian activity before the age of 40 years and is characterized by irregular or absent periods and reduced fertility. Symptoms include those associated with the natural menopause (night sweats and vaginal dryness), and with the long-term adverse effects of estrogen deficiency (osteoporosis and cardiovascular disease): the latter is believed to explain the shorter life expectancy associated with POI. OBJECTIVE AND RATIONALE The objective of the current review was to collect all relevant studies supporting recommendations on the indications, treatment options, and risks of hormone replacement therapy (HRT) (estrogen, progestogens and androgens) for women with POI. SEARCH METHODS The current review was written based on the best available evidence on the topic collected for the recently published ESHRE guideline on the management of women with POI. PUBMED/MEDLINE and the Cochrane library were searched in a stepwise approach. Relevant references were summarized in evidence tables, with assessment of the quality. OUTCOMES HRT is strongly recommended for women with POI, mainly for vasomotor and genito-urinary symptom relief. In addition, HRT has been shown to have a role in bone protection and probably also in primary prevention of cardiovascular disease. There is little evidence on the optimal type, regimen and dose of HRT; patient preference for route and method of administration of each component of HRT must be considered when prescribing, as should contraceptive needs. In women with POI, physiological replacement of estrogen (and progesterone) is essential for their health, and the controversies that surround the use of HRT in postmenopausal women do not apply. LIMITATIONS, REASONS FOR CAUTION N/A. WIDER IMPLICATIONS New areas of study on HRT for women with POI should focus on life expectancy, quality of life and neurological function. Furthermore, randomized controlled trials comparing transdermal estradiol with oral estrogens with regard to efficacy, patient satisfaction and side effects are urgently needed. STUDY FUNDING/COMPETING INTERESTS The authors received no funding for the review. The costs for the development of the ESHRE guideline were covered by ESHRE. The authors have no conflicts of interest to disclose.

Abstract
Introduction The National Institute for Health and Care Excellence (NICE) guideline on the diagnosis and management of the menopause states that women who are likely to go through the menopause as a result of surgical treatment should be offered information about the menopause and the importance of starting hormonal replacement therapy before they have their treatment. Objectives To determine compliance with NICE guidelines at the Royal Derby Hospital. Study design We undertook a retrospective review of all pre-menopausal women undergoing bilateral salpingo-oophorectomy for benign pathology between 1 January 2016 and 30 June 2016. Results Thirty-six cases were reviewed. Women were aged between 32.5 and 49.8 years old (median 45.13, inter-quartile range 42.6-47.6). The commonest indications for bilateral salpingo-oophorectomy were dysfunctional uterine bleeding (36.1%), chronic pelvic pain (30.5%), complex cyst (13.9%), and pre-menstrual syndrome (13.9%). Fifteen women (41.7%) did not have hormonal replacement therapy discussed. Only two (5.6%) had hormonal replacement therapy discussed pre-operatively. The remaining 19 had hormonal replacement therapy discussed post-operatively, either on the ward prior to discharge (n = 3) or, more commonly, in clinic six to eight weeks later. Although hormonal replacement therapy was only contraindicated in one woman (3%), it was only prescribed to five (24%). Results were slightly better for women under 40 but still only 28.6% had hormonal replacement therapy discussed with them pre-operatively. Conclusion This audit has demonstrated that compliance with the NICE guidelines is poor. We suspect similar results might be found in other gynaecology departments nationally. A hospital guideline to aid clinicians and a patient information sheet to educate women has been devised. A re-audit is planned six months after ratification of these documents.

Abstract
Growing evidence indicates that adiposity is associated with breast cancer risk and negatively affects breast cancer recurrence and survival, a paracrine role of mammary adipose tissue being very likely in this process. In contrast to other adipose depots, occurrence of a sub-inflammatory state of mammary adipose tissue defined by dying adipocytes surrounded by macrophages forming crown-like structures in overweight and obese subjects, remains only partially described. In a general population of breast cancer patients (107 patients) mostly undergoing breast-conserving surgery, we found a positive association between patient's body composition, breast adipocytes size, and presence of crown-like structures in mammary adipose tissue close to the tumor. Overweight (BMI: 25.0-29.9 kg/m2) and obese (BMI ≥ 30.0 kg/m2) patients have 3.2 and 6.9 times higher odds ratio of crown-like structures respectively, compared with normal weight patients. The relatively small increase in adipocyte size in crown-like structures positive vs. negative patients suggests that mammary adipose tissue inflammation might occur early during hypertrophy. Our results further highlight that body mass index is an adequate predictor of the presence of crown-like structures in mammary adipose tissue among postmenopausal women, whereas in premenopausal women truncal fat percentage might be more predictive, suggesting that mammary adipose tissue inflammation is more likely to occur in patients exhibiting visceral obesity. Finally, the presence of crown-like structures was positively associated with systemic markers such as the Triglyceride/High-density lipoprotein-cholesterol ratio serum C-reactive protein and glucose/(HbA1c) glycated Haemoglobin. These compelling results demonstrate that excess adiposity, even in overweight patients, is associated with mammary adipose tissue inflammation, an event that could contribute to breast cancer development and progression.

Abstract
INTRODUCTION Hormone replacement therapy (HRT) and walking were investigated independently and in combination, to determine which treatment provided most effect on bone turnover in postmenopausal women. METHODS Using a randomised double-blind pilot study, 10 subjects received HRT (transdermal estradiol, 50 μg/day and oral MPA 5 mg/day) and 12 received placebo for 20 weeks. Following a baseline period of treatment, both groups undertook a graduated walking regimen, which increased in intensity, duration and frequency parameters from weeks 8-20. Measurements of aerobic capacity, female sex hormones, bone formation markers [osteocalcin (OC) and bone alkaline phosphatase (BAP)] and bone resorption markers [deoxypyridinoline (DPD) and pyridinoline (PYR)] were measured at baseline (T1), week 8 (T2) and week 20 (T3). RESULTS Age, time of postmenopause, weight or body mass index were no different between each groups. The HRT group had significantly higher estradiol levels compared with the placebo group at T2 and T3. FSH and LH levels were significantly reduced following HRT. DPD and PYR were significantly reduced from baseline levels at T2 and T3 with HRT. No significant changes occurred in OC or BAP levels with either HRT or walking. Walking did not change bone turnover markers in either the HRT or placebo group. CONCLUSION HRT reduces bone resorption, however, walking alone at the intensity and duration prescribed, or the combination of HRT and walking, provided no additional benefit after menopause. Therefore, HRT, but not walking is an effective treatment in reducing bone turnover in postmenopause women.

Abstract
INTRODUCTION Independently, hormone therapy and exercise have well-established protective effects on bone parameters. The combined effects of hormone therapy and exercise, however, are less clear. We, therefore, examined the effects of hormone therapy on bone turnover markers in postmenopausal women undergoing regular high intensity exercise. METHODS In a randomised, double blind study, postmenopausal athletes competing at Masters level, received either hormone therapy (50 μg transdermal oestradiol, 5 mg MPA, n = 8) or placebo (n = 7) for 20 weeks. Women were tested before and after treatment for plasma concentrations of oestradiol, FSH, LH, and serum bone formation marker -osteocalcin (OC); and urine bone resorption markers-pyridinoline (PYD) and deoxypyridinoline (DPD). RESULTS As a result of treatment with hormone therapy there were significant reductions in levels of FSH (73.3 ± 13.7 to 48.6 ± 10.5 mmol/L, p = 0.01) and bone resorption markers (PYD, 81.9 ± 7.7 to 57.8 ± 3.7 nmol/mmol Cr, p = 0.001, and DPD, 18.5 ± 3.1 to 11.8 ± 2.1 nmol/mmol Cr, p = 0.01). Oestradiol and bone formation markers were not significantly altered as a result of hormone therapy. There were no changes to any variables with placebo treatment. CONCLUSION Hormone therapy reduced bone resorption, but not bone formation, in postmenopausal athletes. These favorable reductions in bone turnover; therefore, provide an effective treatment in combination with high intensity exercise to further reduce the subsequent risk of osteoporosis and associated fractures.

Abstract
Objective Bilateral oophorectomy leads to reduced bone mineral density (BMD), and reduced BMD is associated with increased marrow fat and reduced marrow perfusion. Purpose of this study was to investigate how soon these changes occur following surgical oophorectomy. Materials and Methods Six patients who underwent hysterectomy and bilateral salpingo-oophorectomy were studied. At baseline, mean patient age was 49.5 years (range: 45-54 years). Third lumbar vertebral body BMD measurement using quantitative CT, marrow fat fraction (FF) using MR spectroscopy and marrow perfusion using dynamic contrast enhanced MRI were conducted immediately prior to surgery and at 3, 9, and 21 months after surgery. Results Reduced BMD, increased marrow FF, and reduced marrow perfusion occurred synchronously post-oophorectomy. There was a sharp decrease of 12.5 ± 7.2% in BMD (n = 6), a sharp increase of 92.2 ± 46.3% (n = 6) in FF, a sharp decrease of 23.6 ± 3.9% in maximum contrast enhancement (n = 5), and of 45.4 ± 7.7% for enhancement slope (n = 5) during the initial 3 months post surgery. BMD and marrow perfusion continued to decrease, and marrow FF continued to increase at a slower rate during the following 18 months. Friedman test showed a significant trend for these changes (p < 0.05). Conclusion Bilateral oophorectomy leads to a rapid decrease in lumbar BMD, an increase in marrow fat content, and a decrease in marrow blood perfusion.

Abstract
Bone mineral density (BMD) estimates for the proximal femur using Dual Energy X-ray Absorptiometry (DXA) are currently considered the standard for making a diagnosis of osteoporosis in an individual patient using BMD alone. We have compared BMD results from a commercial Quantitative CT (QCT) BMD analysis system, “CTXA Hip”, which provides clinical data for the proximal femur, to results from DXA. We have also used CTXA Hip to determine cortical and trabecular contributions to total BMD. Sixty-nine patients were scanned using 3D QCT and DXA. CTXA Hip BMD measurements for Total Hip and Femoral Neck were compared to DXA results. Twenty-two women were scanned at 0,1,2 years and CTXA Hip and DXA results analyzed for long-term reproducibility. Long-term reproducibility calculated as root-mean-square averages of SDs in vivo was 0.012 g/cm2 (CV = 1.8%) for CTXA Total Hip and 0.011 g/cm2 (CV = 2.0%) for CTXA Femoral Neck compared to 0.014 g/cm2 (CV = 2.0%) and 0.016 g/cm2 (CV = 2.7%), respectively, for DXA. The correlation of Total Hip BMD CTXA vs. DXA was R = 0.97 and for Femoral Neck was R = 0.95 (SEE 0.044 g/cm2 in both cases). Cortical bone comprised 62±5% (mean ± SD) of total hipbone mass in osteoporotic women. CTXA Hip provides substantially the same clinical information as conventional DXA and in addition provides estimates of BMD in separate cortical and trabecular bone compartments, which may be useful in evaluation of bone strength.

Abstract
We now appreciate that estrogen is a pleiotropic gonadal steroid that exerts profound effects on the plasticity and cell survival of the adult brain. Over the past century, the life span of women has increased, but the age of the menopause remains constant. This means that women may now live over one third of their lives in a hypoestrogenic, postmenopausal state. The impact of prolonged hypoestrogenicity on the brain is now a critical health concern as we realize that these women may suffer an increased risk of cognitive dysfunction and neurodegeneration due to a variety of diseases. Accumulating evidence from both clinical and basic science studies indicates that estrogen exerts critical protective actions against neurodegenerative conditions such as Alzheimer's disease and stroke. Here, we review the discoveries that comprise our current understanding of estrogen action against neurodegeneration. These findings carry far-reaching possibilities for improving the quality of life in our aging population.

Abstract
Biochemical markers of bone turnover (bone turnover markers, BTMs) can be used to study changes in bone remodelling in osteoporosis. Investigators and clinicians should be aware of the appropriate sample collection and storage conditions for optimum measurements of these markers. Improvements in the variability of BTM measurements have resulted from the development of assays for automated analysers, and from international consensus regarding their use. Appropriate reference intervals should be used for the optimum interpretation of results. BTMs can provide information that is useful for the management of patients with osteoporosis, for both the initial clinical assessment and for guiding and monitoring of treatment. BTMs are clinically useful to determine possible causes of secondary osteoporosis by identifying patients with high bone turnover and rapid bone loss. In the follow-up of treatment response, BTM levels respond rapidly to both anabolic and antiresorptive treatments. BTM changes can also be used for understanding the mechanism of action of drugs in development and identifying the correct dose; they are also potentially useful as surrogate biomarkers for fracture.

Abstract
The cardinal features of Turner syndrome (TS) are short stature, congenital abnormalities, infertility due to gonadal dysgenesis, with sex hormone insufficiency ensuing from premature ovarian failure, which is involved in lack of proper development of secondary sex characteristics and the frequent osteoporosis seen in Turner syndrome. But sex hormone insufficiency is also involved in the increased cardiovascular risk, state of physical fitness, insulin resistance, body composition, and may play a role in the increased incidence of autoimmunity. Severe morbidity and mortality affects females with Turner syndrome. Recent research emphasizes the need for proper sex hormone replacement therapy (HRT) during the entire lifespan of females with TS and new hypotheses concerning estrogen receptors, genetics and the timing of HRT offers valuable new information. In this review, we will discuss the effects of estrogen and androgen insufficiency as well as the effects of sex HRT on morbidity and mortality with special emphasis on evidence based research and areas needing further studies.

Abstract
Estradiol (E(2)) and progesterone (P(4)) collaborate within bone remodelling on resorption (E(2)) and formation (P(4)). We integrate evidence that P(4) may prevent and, with antiresorptives, treat women's osteoporosis. P(4) stimulates osteoblast differentiation in vitro. Menarche (E(2)) and onset of ovulation (P(4)) both contribute to peak BMD. Meta-analysis of 5 studies confirms that regularly cycling premenopausal women lose bone mineral density (BMD) related to subclinical ovulatory disturbances (SODs). Cyclic progestin prevents bone loss in healthy premenopausal women with amenorrhea or SOD. BMD loss is more rapid in perimenopause than postmenopause-decreased bone formation due to P(4) deficiency contributes. In 4 placebo-controlled RCTs, BMD loss is not prevented by P(4) in postmenopausal women with increased bone turnover. However, 5 studies of E(2)-MPA co-therapy show greater BMD increases versus E(2) alone. P(4) fracture data are lacking. P(4) prevents bone loss in pre- and possibly perimenopausal women; progesterone co-therapy with antiresorptives may increase bone formation and BMD.

Abstract
Few studies have examined the effects of leisure physical activity (PA) participation on bone mass and geometry in postmenopausal women using peripheral quantitative computed tomography (pQCT). The purpose of this study was to determine associations between leisure PA participation and bone mass and geometry at the radius and tibia in a Canadian cohort of healthy postmenopausal women (n=234, mean age 62 years). Leisure PA participation was assessed using the Minnesota Leisure Time Physical Activity Questionnaire and by generating a total activity score (TAS, mean=105, range=0-840). Bone mass and geometry at the distal and midshaft sites of the non-dominant radius and tibia were measured using pQCT. Associations between TAS and bone mass and geometry variables were determined using linear regression models adjusted for clinically relevant confounding variables. TAS was positively and significantly associated with total content, total area, cortical content and cortical area at the midshaft sites of the radius and tibia (p<0.05 for all associations). TAS was also positively and significantly associated with bone bending and torsional strength parameters at the midshaft radius and tibia (p<0.05 for all associations). No associations were observed between TAS and trabecular bone parameters. Leisure PA participation is positively associated with cortical bone mass and geometry as well as bending and torsional strength at weight-bearing and non-weight-bearing bone sites and may have the potential to modify bone strength and influence bone fragility in postmenopausal women.

Abstract
Bone health may be impaired in many patients being treated for cancer. Primary tumors that reside in or form metastases to bone can result in compromised skeletal integrity. It has also been increasingly recognized that patients undergoing therapies for treatment of cancer are at higher risk of bone loss. These include androgen-deprivation therapy for prostate cancer and aromatase inhibitor therapy for breast cancer, among others. Hypogonadism induced by many of these cancer treatments results in bone loss and increases the risk of osteoporosis and fractures. Progress has been made in identifying the role of oral and intravenous bisphosphonates to prevent bone loss in these patients. This review discusses bone loss associated with cancer treatments, with a focus on breast cancer, prostate cancer, and survivors of childhood malignancies.

Abstract
Many patients with prolactin secreting pituitary tumors have decreased bone mineral. The bone loss is associated with an increase in bone resorption and is secondary to prolactin-induced hypogonadism. In both sexes trabecular bone in the spine and hip is more affected than cortical bone in the distal radius. Normalization of prolactin and restoration of gonadal function increases bone density but is not associated with normalization of bone mass. It is not known whether the bone loss in hyperprolactinemic subjects represents a failure to achieve peak bone mass or is due to accelerated bone loss. Despite low bone density hyperprolactinemic subjects do not demonstrate increased fractures. The association between prolactin, weight gain and obesity suggests that prolactin may also be a modulator of body composition and body weight. It is not known whether hyperprolactinemia associated weight gain is due to stimulation of lipogenesis or due to disruption of central nervous system dopaminergic tone. Hyperprolactinemia is also associated with insulin resistance and endothelial dysfunction which may improve after normalization of prolactin. The clinical significance of these findings and the precise role of prolactin in regulation of weight and metabolism remain to be elucidated.

Abstract
Information on the pathophysiology of glucocorticoid-induced osteoporosis (GIO) is limited, since its clinical picture often reflects a combined effect of glucocorticoids (GC) and the treated systemic disease (i.e., inflammation and immobility). In 50 healthy adult (30-mo-old) primiparous Göttingen minipigs, we studied the short-term (8 mo, n = 30) and long-term (15 mo, n = 10) effect of GC on bone and mineral metabolism longitudinally and cross-sectionally compared with a control group (n = 10). All animals on GC treatment received prednisolone orally at a dose of 1.0 mg x kg body wt(-1) x day(-1) for 8 wk and thereafter at 0.5 mg/kg body wt(-1) x day(-1). In the short term, GC reduced bone mineral density (BMD) at the lumbar spine by -47.5 +/- 5.1 mg/cm(3) from baseline (P < 0.001), which was greater (P < 0.05) than the loss [not significant (NS)] in the control group of -11.8 +/- 12.6 mg/cm(3). Calcium absorption decreased from baseline by -2,488 +/- 688 mg/7 days (P < 0.001) compared with -1,380 +/- 1,297 mg/7 days (NS) in the control group. Plasma bone alkaline phosphatase (BAP) decreased from baseline by -17.8 +/- 2.2 U/l (P < 0.000), which was significantly different (P < 0.05) from the value of the control group of -1.43 +/- 4.8 U/l. In the long term, the loss of BMD became more pronounced and bone mineral content (BMC), trabecular thickness, mechanical stability, calcium absorption, 25-hydroxyvitamin D(3), 1,25-dihydroxyvitamin D(3), and parathyroid hormone tended to be lower compared with the control group. There was a negative association between the cumulative dose of GC and BMD, which was associated with impaired osteoblastogenesis. In conclusion, the main outcomes after GC treatment are comparable to symptoms of GC-induced osteoporosis in human subjects. Thus the adult Göttingen miniature pig appears to be a valuable animal model for GC-induced osteoporosis.

Abstract
OBJECTIVE To review the data on the effect of early menopause on bone. Do women undergoing early menopause develop lower bone mineral density at an earlier age and do they have a higher incidence of osteoporotic fractures? Is there a difference on bone between women who undergo early natural menopause compared to women who have early menopause after oophorectomy? RESULTS The earlier in life that menopause occurs, the lower the bone density will be later in life. Low bone density is associated with a higher fracture rate, and several studies show a relationship between early menopause, oophorectomy, and an increase in osteoporotic fractures. CONCLUSIONS Early menopause is a risk factor for osteoporosis. Women with an early menopause should have bone density testing performed within 10 years of menopause so that osteopenia or osteoporosis will be diagnosed early and appropriate anti-resorptive therapy initiated.

Abstract
Oestrogen therapy is the gold standard treatment for hot flushes/night sweats, but it and oestrogen/progestin are not suitable for all women. MPA (medroxyprogesterone acetate) reduces hot flushes, but its effectiveness compared with oestrogen is unknown. In the present study, oral oestrogen [CEE (conjugated equine oestrogen)] and MPA were compared for their effects on hot flushes in a planned analysis of a secondary outcome for a 1-year randomized double-blind parallel group controlled trial in an urban academic medical centre. Participants were healthy menstruating women prior to hysterectomy/ovariectomy for benign disease. A total of 41 women {age, 45 (5) years [value is mean (S.D.)]} were enrolled; 38 women were included in this analysis of daily identical capsules containing CEE (0.6 mg/day) or MPA (10 mg/day). Demographic variables did not differ at baseline. Daily data provided the number of night and day flushes compared by group. The vasomotor symptom day-to-day intensity change was assessed by therapy assignment. Hot flushes/night sweats were well controlled in both groups, one occurred on average every third day and every fourth night. Mean/day daytime occurrences were 0.363 and 0.187 with CEE and MPA respectively, but were not significantly different (P=0.156). Night sweats also did not differ significantly (P=0.766). Therapies were statistically equivalent (within one event/24 h) in the control of vasomotor symptoms. Day-to-day hot flush intensity decreased with MPA and tended to remain stable with CEE (P<0.001). In conclusion, this analysis demonstrates that MPA and CEE are equivalent and effective in the control of the number of hot flushes/night sweats immediately following premenopausal ovariectomy.

Abstract
OBJECTIVE The objective of this study was to evaluate clinical factors associated with choosing prophylactic bilateral salpingo-oophorectomy (BSO) over surveillance in women with a BRCA1 or BRCA2 mutation. METHODS Between 1996 and 2005, 139 women who tested positive for a BRCA1 or BRCA2 mutation were identified. Thirty-three women were excluded due to a personal history of ovarian or fallopian tube cancer before genetic testing, resulting in 106 women for the final analysis. The characteristics of women who underwent prophylactic BSO were compared with those choosing surveillance. RESULTS Sixty-five of the BRCA mutation carriers (61%) underwent prophylactic BSO. Median age at BSO was 45.6 years. Median time from disclosure of genetic test results to surgery was 4.6 months. Eighty-five percent of women who underwent prophylactic BSO were parous compared with 66% of women who chose surveillance (P = .03). A previous diagnosis of breast cancer was noted in 72% of women who underwent prophylactic BSO compared with 46% of women undergoing surveillance (P < .01). Fifty-two women (80%) had hysterectomy performed at the time of BSO. Two women had incidental ovarian cancer diagnosed at time of surgery. CONCLUSION Age greater than 40 years, parity, and a personal history of breast cancer were associated with choosing prophylactic BSO in our cohort. A short time interval was noted from the time of receiving positive genetic test results to undergoing prophylactic surgery.

Abstract
OBJECTIVE To compare the biochemical markers of bone turnover in hypoestrogenic women who had been on the standard dosage of Premarin 0.625 mg to that of the age-matched women who were menstruating spontaneously. STUDY DESIGN Chinese women between 25 and 40 years of age with a diagnosis of hypoestrogenism who had been on Premarin 0.625 mg daily for more than 1 year were recruited. The control group comprised age- and parity-matched women who had proven ovulation by mid-cycle serum luiteinising hormone surge. Serum osteocalcin and serum pyridinoline crosslink, markers of bone formation and resorption, respectively, were measured by enzyme-linked immunosorbent assays. RESULTS Twenty hypoestrogenic Chinese patients with a mean age of 36.2 were recruited as the study group. The same number of controls was recruited. There were no smokers in either group. The body weight, body height and body mass indices were comparable between the two groups. Both biochemical markers of bone metabolism did not differ between the two groups. CONCLUSION The average bone turn-over rate in young hypoestrogenic Chinese women on Premarin 0.625 mg/day was similar to that of normal menstruating women.

Abstract
BACKGROUND Women with the Lynch syndrome (hereditary nonpolyposis colorectal cancer) have a 40 to 60 percent lifetime risk of endometrial cancer and a 10 to 12 percent lifetime risk of ovarian cancer. The benefit of prophylactic gynecologic surgery for women with this syndrome has been uncertain. We designed this study to determine the reduction in the risk of gynecologic cancers associated with prophylactic hysterectomy and bilateral salpingo-oophorectomy in women with the Lynch syndrome. METHODS Three hundred fifteen women with documented germ-line mutations associated with the Lynch syndrome were identified. Women who had undergone prophylactic hysterectomy (61 women) and women who had undergone prophylactic bilateral salpingo-oophorectomy (47 women) were matched with mutation-positive women who had not undergone the procedure in question (210 women for the analysis of endometrial cancer and 223 for the analysis of ovarian cancer). Women who had undergone prophylactic surgery and their matched controls were followed from the date of the surgery until the occurrence of cancer or until the data were censored at the time of the last follow-up visit. RESULTS There were no occurrences of endometrial, ovarian, or primary peritoneal cancer among the women who had undergone prophylactic surgery. Endometrial cancer was diagnosed in 69 women in the control group (33 percent), for an incidence density of 0.045 per woman-year, yielding a prevented fraction (the proportion of potential new cancers prevented) of 100 percent (95 percent confidence interval, 90 to 100 percent). Ovarian cancer was diagnosed in 12 women in the control group (5 percent), for an incidence density of 0.005 per woman-year, yielding a prevented fraction of 100 percent (95 percent confidence interval, -62 to 100 percent). CONCLUSIONS These findings suggest that prophylactic hysterectomy with bilateral salpingo-oophorectomy is an effective strategy for preventing endometrial and ovarian cancer in women with the Lynch syndrome.

Abstract
INTRODUCTION Low-carbohydrate diets have become popular as weight loss techniques. These diets are high in protein, saturated fats, and omega-6 fatty acids. They also lead to a ketogenic state. These factors could lead to increased bone turnover. This study was designed to see whether a low-carbohydrate diet would lead to increased bone turnover in humans. METHODS Thirty patients (15 study subjects and 15 controls) were recruited for this 3-month study. The 15 patients on the diet were instructed to consume less than 20 g of carbohydrates per day for the 1st month and then less than 40 g per day for months 2 and 3. Control subjects had no restrictions on their diet. The primary end point was urinary N-telopeptide (UNTx) at 3 months. Secondary end points included UNTx at 1 month, bone-specific alkaline phosphatase (BSAP) at 1 month, bone turnover ratio (BSAP/UNTx) at 1 month, and weight loss. RESULTS The mean UNTx in the study subjects increased by 1.6 [95% confidence interval (CI) +/-22.8] compared with an increase of 1.9 (95% CI +/-17.6) in the controls at 3 months (p=0.86). The mean UNTx decreased by 2.2 (95% CI +/-27.2) and 3.1 (95% CI +/-17.6) at 1 month in the dieters and controls, respectively (p=0.36). The mean BSAP decreased by 0.53 (95% CI +/-2.96) in the dieters and increased by 0.34 (95% CI +/-2.92) in the controls at 1 month (p=0.27). The bone turnover ratio increased by 0.08 (95% CI +/-0.81) in the dieters and by 0.05 (95% CI +/- 0.27) in the controls at 1 month (p=0.78). The dieters lost 6.39 kg versus 1.05 kg for the controls at 3 months (p=0.0008). CONCLUSIONS Although the patients on the low-carbohydrate diet did lose significantly more weight than the controls did, the diet did not increase bone turnover markers compared with controls at any time point. Further, there was no significant change in the bone turnover ratio compared with controls.

Abstract
OBJECTIVE The purpose of this study was to evaluate the action of progestins on bone metabolism in early menopausal women. STUDY DESIGN One hundred thirty-two menopausal women were randomized into a 2-year double-blinded, placebo-controlled clinical trial. There were 6 treatment groups: micronized progesterone (P 4 ) 300 mg/day; medroxyprogesterone acetate (MPA) 10 mg/day; norethindrone (NET) 1 mg/day; micronized estradiol (E 2 ) 1 mg/day; E 2 1 mg/day + MPA 10 mg/day; and placebo. All subjects received 1000 mg of calcium and 400 IU of vitamin D/day. Primary outcome variables were bone mineral density (BMD) changes at the spine and hip. Secondary variables were bone turnover markers. RESULTS With E 2 or E 2 +MPA treatment, BMD at L2-L4 increased by 2% to 4% over 2 years. Bone mineral density (BMD) at the spine followed a decreasing trend with MPA, P 4 , and placebo treatments. With NET treatment, BMD did not change from baseline. At the femoral neck site, BMD did not change significantly for any treatment group. Bone resorption and bone formation markers decreased with E 2 or E 2 +MPA treatment, and did not change appreciably with all 3 progestin-alone treatments. There were no vertebral or hip fractures observed during the trial. CONCLUSION Estrogen remains the primary bone active agent in hormone therapy, while progestins have significantly less activity. The selection of the appropriate progestin in hormone therapy should be based on criteria other than bone activity.

Abstract
BACKGROUND Most parents are very concerned about the height of their children. Biochemical markers of bone formation and resorption may provide useful clinical predictors for bone growth. Tartrate-resistant acid phosphatase 5b (TRAcP 5b) has been advocated as a biomarker of osteoclast activity and bone resorption. However, the TRAcP 5b levels of children at different ages are still unknown. It is necessary to accumulate and analyze the data for healthy children at different ages. OBJECTIVES We use an improved immunoassay for bone TRAcP 5b to examine sera from children to see whether it is a significant marker of bone growth. METHODS Serum, including cord blood, was collected from 404 normal Chinese children (age range 0-17 years; 225 male, 179 female). The venous blood was withdrawn from the peripheral vein and stored at 4 degrees C before centrifugation for serum collection. All sera were stored at -70 degrees C and thawed at 37 degrees C immediately before TRAcP 5b levels were measured. Bone-specific alkaline phosphatase (BAP) was also used for comparison with TRAcP 5b levels at different ages. RESULTS TRAcP 5b levels were extremely high in infants of both genders, gradually decreasing with age (p <0.001). A second peak in TRAcP 5b values occurred at 12-13 and 10-11 years in males and females, respectively (p <0.001). Age alone, as well as age-related changes between the male and female groups, were independent predictors of TRAcP 5b levels (p <0.001). There was no significant between-gender difference in serum TRAcP 5b levels for any age group (p = 0.682). BAP values did not show a significant second peak in females. Age and gender alone, as well as the age-related changes between male and female groups, were independent predictors of BAP values (p <0.001). CONCLUSION Preliminary results were established for serum TRAcP 5b and BAP values of normal Chinese children of different ages. Elevated serum TRAcP 5b values were observed during infancy and puberty for both genders. The pattern of this age-related change in serum TRAcP 5b levels is similar to the shape of the standard height velocity curve for healthy children. Values of BAP were less specific than TRAcP 5b. These data may prove valuable as a normal reference in future research about bone markers.

Abstract
In view of the fact that fractures are the clinically relevant events, risk factors for fractures are discussed first. Bone mineral density (BMD) appears to be a much less important risk factor for the most severe hip fractures than the risk of falling. No results of experimental studies on hormones and fractures at advanced age are available. An overview of the effects of progestins on bone is given. Effects of progestins on bone have been studied by in vitro experiments using cell lines and by more relevant clinical observations. Prospective studies have been conducted following the use of progestins contained in oral contraceptives, alone or in combination with oestrogens; long-term contraception by injection of depot preparations; so-called "add-back" hormonal therapy attempting to reverse the adverse effects of gonadotropin releasing hormone agonists on bone and after different regimens of hormone replacement therapy (HRT) in postmenopausal women. From the data there are no indications that the various progestins, used in clinical practice, have either a bone-protective or an oestrogen antagonistic activity. Progestins do not add or subtract much of the protective action of oestrogens on the bones.

Abstract
OBJECTIVE The aim of this study was to understand the strengths and limitations of current prevention, detection, and screening methods for ovarian cancer and to identify research areas to improve prevention, screening, and detection of the disease for all women as well as for women carrying a mutation in the BRCA1/2 genes. METHODS We convened an ovarian cancer symposium at the University of Pittsburgh in May 2002. Nineteen leading scientists representing disciplines such as epidemiology, molecular biology, pathology, genetics, bioinformatics, and psychology presented the latest data on ovarian cancer prevention, screening, and early detection. RESULTS Ovarian cancer is the most common cause of death from a gynecologic malignancy in the United States. Because survival depends on stage of diagnosis, early detection is critical in improving clinical outcome. However, existing screening techniques (CA125, transvaginal ultrasound) have not been shown to reduce morbidity or mortality. Moreover, with the exception of oral contraceptives, there are no available chemopreventive agents. Bilateral salpingo-oophorectomy also has been shown to reduce incidence, but this procedure has several drawbacks in terms of a woman's reproductive, cardiovascular, skeletal, and mental health. CONCLUSIONS Better methods to prevent, detect, and screen for ovarian cancer in all women, but particularly in high-risk women carrying mutations in BRCA1/2, are urgently needed. This article reviews the current state of knowledge in the etiology, prevention, and early detection of ovarian cancer and suggests several areas for future clinical, epidemiologic, and laboratory-based research.
