Efficacy and safety of medical therapy for low bone mineral density in patients with inflammatory bowel disease: a meta-analysis and systematic review. Clin Gastroenterol Hepatol 2014; 12:32-44.e5.

Abstract
BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) are at risk for osteoporosis and fracture. However, the efficacy of medical treatments for osteoporosis in increasing bone mineral density (BMD) in patients with IBD has not been well characterized. METHODS We conducted a meta-analysis and systematic review of controlled trials to evaluate the efficacy and safety of medical therapies used for low BMD in patients with IBD (Crohn's disease, ulcerative colitis, or indeterminate colitis). We searched MEDLINE, EMBASE, Google scholar, the University Hospital Medical Information Network (UMIN) Clinical Trials Registry, and Cochrane Central Register of Controlled Trials for studies that assessed the efficacy of medical treatment for low BMD in patients with IBD. We also manually searched abstracts from scientific meetings and bibliographies of identified articles for additional references. The primary outcome assessed was changes in BMD at the lumbar spine. We also collected data on hip BMD, numbers of new fractures, and adverse effects. Data were pooled by using random-effects models and by mixed-effects analysis for primary aims, when subgroup analysis by individual drug was possible. RESULTS We analyzed data from 19 randomized controlled studies; 2 used calcium and vitamin D as therapies, 13 used bisphosphonates, 4 used fluoride, 1 used calcitonin, and 1 used low-impact exercise. The pooled effect of bisphosphonates was greater than that of controls in increasing BMD at the lumbar spine (standard difference in means, 0.51; 95% confidence interval, 0.29-0.72) and hip (standard difference in means, 0.26; 95% confidence interval, 0.04-0.49) with comparable tolerability, and the risk of vertebral fractures was reduced. Fluoride increased lumbar spine BMD, but its ability to reduce risk of fracture was unclear. There was no evidence that the other interventions increased BMD. CONCLUSIONS On the basis of a meta-analysis, bisphosphonate is effective and well tolerated for the treatment of low BMD in patients with IBD and reduces the risk of vertebral fractures. There are insufficient data to support the efficacy of calcium and vitamin D, fluoride, calcitonin, or low-impact exercise. However, the small number of randomized controlled trials limited our meta-analysis.

Abstract
INTRODUCTION Oral contraceptives (OCs) are considered as one of the most common risk factor of venous thromboembolism (VTE) in childbearing age. Some of the recent researches indicate that the odds of VTE may be even higher with newer generations of OCs. The present meta-analysis was designed to evaluate the effect of different generation of OCs on the occurrence of VTE. METHODS Two researchers independently ran a thorough search in Pubmed, ISI Web of Science, EMBASE, CINAHL and Scopus databases regarding study keywords including thromboembolic event, thromboembolism, embolism, thromboembolic, thrombotic and thrombosis, combined with oral contraceptive. The outcomes were the incidence of diagnosed thromboembolism, such as deep vein thrombosis, pulmonary embolism and cerebral venous thrombosis. Based on the heterogeneity of the studies, random effect model was used and pooled odds ratio was reported. RESULTS Three cohort and 17 case-control studies with 13,265,228 subjects were entered into meta-analysis. Analysis showed that the odds of VTE in women taking OCs are more than three-fold (OR=3.13; 95% CI: 2.61-3.65). The risk of VTE in women taking first-, second- and third-generation OCs are 3.5 fold (OR=3.48; 95% CI: 2.01-4.94), 3 fold (OR=3.08; 95% CI: 2.43-3.74) and 4.3 fold (OR=4.35; CI: 3.69‒5.01), respectively. CONCLUSION It seems that the risk of VTE is not same between different generations of OCs, so that third-generation has highest risk. Taking second and third-generation OCs increases the risk of VTE up to 3 and 4.3 fold, respectively. The researchers of the present study suggest that more trials be designed in relation to the effect of newer generations of OCs in different communities.

Abstract
The diagnosis of pulmonary embolism (PE) is frequently considered in patients presenting to the emergency department or when hospitalized. Although early treatment is highly effective, PE is underdiagnosed and, therefore, the disease remains a major health problem. Since symptoms and signs are non specific and the consequences of anticoagulant treatment are considerable, objective tests to either establish or refute the diagnosis have become a standard of care. Diagnostic strategy should be based on clinical evaluation of the probability of PE. The accuracy of diagnostic tests for PE are high when the results are concordant with the clinical assessment. Additional testing is necessary when the test results are inconsistent with clinical probability. The present review article represents the consensus-based recommendations of the Interdisciplinary Association for Research in Lung Disease (AIMAR) multidisciplinary Task Force for diagnosis and treatment of PE. The aim of this review is to provide clinicians a practical diagnostic and therapeutic management approach using evidence from the literature.

Abstract
Hormone Replacement Therapy (HRT) has received consistently bad press, despite re-analysis of previous data new studies and supporting Consensus Statements from leading national and international societies. Many women have been convinced by women's journals and the media not to even consider HRT as an option and, General Practitioners, still limit duration to 5 years or, will, arbitrarily, discontinue prescriptions in the early 50s. This article seeks to make sense of our current position. Previous and new evidence on the safety of HRT is reviewed. New data on the long-term consequences of non-treatment of women with Premature Ovarian Insufficiency (POI) is presented and the dichotomy of the older female workforce is explored. From this, a logical plan of management emerges.

Abstract
Pulmonary embolism is one of the most common undiagnosed conditions affecting hospitalized patients. There are a plethora of risk factors for venous thromboembolism and pulmonary emboli. These factors are grouped under the broad triad of hypercoagulability, stasis and injury to provide a framework for understanding. Important risk factors include inherited thrombophilia, age, malignancy and estrogens. These risk factors are reviewed in detail and several risk assessment models are reviewed. These risk assessment models help identify those at risk for disease and therefore candidates for thromboprophylaxis. Diagnosis can be difficult and is aided by clinical decision rules that incorporate clinical scores that define the likelihood of pulmonary embolism. These are important considerations, not only for diagnostic purposes, but also to minimize excessive use of imaging, which increases exposure to and risks associated with radiation. A healthy index of suspicion is often the key to diagnosis.

Abstract
BACKGROUND A diverse range of study designs (e.g. case-control or cohort) are used in the evaluation of adverse effects. We aimed to ascertain whether the risk estimates from meta-analyses of case-control studies differ from that of other study designs. METHODS Searches were carried out in 10 databases in addition to reference checking, contacting experts, and handsearching key journals and conference proceedings. Studies were included where a pooled relative measure of an adverse effect (odds ratio or risk ratio) from case-control studies could be directly compared with the pooled estimate for the same adverse effect arising from other types of observational studies. RESULTS We included 82 meta-analyses. Pooled estimates of harm from the different study designs had 95% confidence intervals that overlapped in 78/82 instances (95%). Of the 23 cases of discrepant findings (significant harm identified in meta-analysis of one type of study design, but not with the other study design), 16 (70%) stemmed from significantly elevated pooled estimates from case-control studies. There was associated evidence of funnel plot asymmetry consistent with higher risk estimates from case-control studies. On average, cohort or cross-sectional studies yielded pooled odds ratios 0.94 (95% CI 0.88-1.00) times lower than that from case-control studies. INTERPRETATION Empirical evidence from this overview indicates that meta-analysis of case-control studies tend to give slightly higher estimates of harm as compared to meta-analyses of other observational studies. However it is impossible to rule out potential confounding from differences in drug dose, duration and populations when comparing between study designs.

Abstract
CONTEXT The long-term effects of pure 17β-estradiol (E₂) depending on route of administration have not been well characterized. OBJECTIVE Our objective was to assess metabolic effects of oral vs transdermal (TD) 17β-E₂ replacement using estrogen concentration-based dosing in girls with Turner syndrome (TS). PATIENTS Forty girls with TS, mean age 16.7 ± 1.7 years, were recruited. DESIGN Subjects were randomized to 17β-E₂ orally or TD. Doses were titrated using mean E₂ concentrations of normally menstruating girls as therapeutic target. E₂, estrone (E₁), and E₁ sulfate (E₁S) were measured by liquid chromatography tandem mass spectrometry and a recombinant cell bioassay; metabolites were measured, and dual-energy x-ray absorptiometry scan and indirect calorimetry were performed. MAIN OUTCOME Changes in body composition and lipid oxidation were evaluated. RESULTS E₂ concentrations were titrated to normal range in both groups; mean oral dose was 2 mg, and TD dose was 0.1 mg. After 6 and 12 months, fat-free mass and percent fat mass, bone mineral density accrual, lipid oxidation, and resting energy expenditure rates were similar between groups. IGF-1 concentrations were lower on oral 17β-E₂, but suppression of gonadotropins was comparable with no significant changes in lipids, glucose, osteocalcin, or highly sensitive C-reactive protein between groups. However, E₁, E₁S, SHBG, and bioestrogen concentrations were significantly higher in the oral group. CONCLUSIONS When E₂ concentrations are titrated to the normal range, the route of delivery of 17β-E₂ does not affect differentially body composition, lipid oxidation, and lipid concentrations in hypogonadal girls with TS. However, total estrogen exposure (E₁, E₁S, and total bioestrogen) is significantly higher after oral 17β-E₂. TD 17β-E₂ results in a more physiological estrogen milieu than oral 17β-E₂ administration in girls with TS.

Abstract
Several aspects of the diagnostic and therapeutic management of women with venous thrombosis are uncertain. In this overview, I will discuss three major areas. First, the contribution of hormone use to venous thromboembolism (VTE) will be discussed as prudent prescribing of safe preparations can further reduce the risk of hormone-related VTE. Uncertainties remain regarding certain low-dose progestagens and transdermal routing of hormones and their associated risk of VTE. Second, I will review the diagnosis, treatment, and prevention of pregnancy-related VTE. As direct evidence is largely absent for these individuals, these areas are subject to extrapolation from the non-pregnant population. There is therefore an urgent need for the evaluation of diagnostic strategies that safely exclude the diagnosis of acute pulmonary embolism in pregnant women without the need for diagnostic imaging, which is currently the gold standard, as no studies have confidently demonstrated the safety of ruling out VTE by clinical probability assessment combined with the use of D-dimer levels. Although identification of women at increased risk of pregnancy-related VTE is relatively well established, controversy remains for asymptomatic women from thrombophilic families. The optimal duration and intensity of anticoagulant treatment for, and prophylaxis of, pregnancy-related VTE with low molecular weight heparin is unknown. Third, anticoagulant therapy to prevent recurrence in women with unexplained recurrent miscarriage has shown to have no benefit and should not be prescribed. However, whether antithrombotic therapy prevents recurrent miscarriage in thrombophilic women, or in women with severe pregnancy complications, remains unknown and urgently requires future research.

Abstract
The media attention surrounding the publication of the initial results of WHI in 2002 led to fear and confusion regarding the use of hormonal therapy (HT) after menopause. This led to a dramatic reduction in prescriptions for HT in the United States and around the world. Although in 2002 it was stated that the results pertained to all women receiving HT, subsequent studies from the Women's Health Initiative (WHI) and others clearly showed that younger women and those close to menopause had a very beneficial risk-to-benefit ratio. Indeed, the results showed similar protective effects for coronary disease and a reduction in mortality that had been shown in earlier observational studies, which had also focused on younger symptomatic women. In younger women, the increased number of cases of venous thrombosis and ischemic stroke was low, rendering them "rare" events using World Health Organization nomenclature. Breast cancer rates were also low and were found to be decreased with estrogen alone. In women receiving estrogen and progestogen for the first time in the WHI, breast cancer rates did not increase significantly for 7 years. Other data suggest that other regimens and the use of other progestogens may also be safer. It has been argued that in the 10 years since WHI, many women have been denied HT, including those with severe symptoms, and that this has significantly disadvantaged a generation of women. Some reports have also suggested an increased rate of osteoporotic fractures since the WHI. Therefore, the question is posed as to whether we have now come full circle in our understanding of the use of HT in younger women. Although it is appropriate to treat women with symptoms at the onset of menopause, because there is no proven therapy for primary prevention, in some women the use of HT for this role may at least be entertained.

Abstract
Many trials on the use of hormone replacement therapy (HRT) have provided contradictory results on its risks and benefits in post-menopausal women. The use of HRT declined globally following publication of the first data from the Women’s Health Initiative (WHI) trial in 2002, with the revelation that there was an increased risk of breast cancer and coronary heart disease (CHD) in postmenopausal women taking HRT. Following this, other leading studies published results that were consistent with these findings, which reduced enthusiasm for HRT use. However, recent publications from the International Menopause Society indicate that HRT is the first-line and most effective treatment for menopausal symptoms. Moreover, when the full results of the WHI trial were subsequently published, it appeared that HRT may confer benefits for CHD prevention below age 60. The statements from the British Menopause Society and the International Menopause Society (IMS) published in 2008 also supported this opinion. These revelations renew interest in HRT use. This paper analyzes the effects of combination versus unopposed HRT on osteoporosis, breast and CHD, endometrial cancer induction, venous thromboembolic disease, lipids and lipoproteins, neuroprotection, and cognitive function in post-menopausal women.

Abstract
Postmenopausal hormone therapy (PMHT) is used for the relief of menopausal symptoms, but the dosage has varied greatly throughout its existence. By the end of the 1990s, PMHT was mainly used to prevent chronic diseases such as osteoporosis, coronary heart disease and dementia, and large prevention trials were undertaken in this context. Following the initial negative reports of these trials, use of PMHT dramatically decreased. These reports noted surprisingly increased risks, notably of coronary heart disease, stroke and breast cancer, in people who used PMHT. Nowadays, considering the currently available data, it seems that an important distinction should be made between the treatment of climacteric symptoms in young, generally healthy, postmenopausal women and the prevention of chronic diseases in elderly women. PMHT seems to be beneficial and safe for postmenopausal symptomatic women aged <60 years. Treatments with a high safety profile should be the preferred option, including low-dose PMHT, oestrogen-only therapy in women who have had a hysterectomy, and vaginal oestrogen therapy for women with atrophic vaginitis. Nonandrogenic progestin might have a reduced thrombotic and breast cancer risk, and transdermal oestrogen could have a reduced thrombotic risk. Nevertheless, PMHT should not be used for the prevention of chronic diseases in the elderly (>70 years old) owing to the increased risk of stroke and breast cancer in these patients.

Abstract
Since the early 1960s, it has been well documented that combined hormonal contraceptives increase the risk of cardiovascular disease. Newer generation of oral formulations, as well as non-oral contraceptives (transdermal and vaginal), have been recently studied for thrombotic risk. This review provides a summary of the association between hormonal contraceptives and venous thromboembolism with emphasis on new formulations of hormonal contraceptives as well as route of administration. A systematic search of Medline database was done for all relevant articles which included women having used third generation pills, and the development of new progestins. Eligible articles published in English and reporting the risk of venous thromboembolism (VTE) (pulmonary embolism or deep venous thrombosis) among users of hormonal contraceptives were reviewed. A quantitative assessment was made from included studies. Current use of drospirenone or cyproterone oral combined contraceptives increased the risk of VTE compared with second generation pills (pooled OR: 1.7; 95% confidence interval [95% CI]: 1.4-2.2 and OR: 1.8; 95% CI: 1.4-2.3, respectively). In the context of contraceptive use, non-oral route of ethinyl-estradiol administration seems to be more thrombogenic than oral route. In contrast, low doses of both oral progestin contraceptives and intrauterine levonorgestrel could be safe with respect to VTE risk. In conclusion, newer generation formulations of hormonal contraceptives, as well as the non-oral hormonal contraceptive, seem to be more thrombogenic than second generation hormonal contraceptives.

Abstract
The cardiovascular safety of widely used combined hormonal contraceptives is still debated. Newer generations of oral formulations as well as non-oral contraceptives (transdermal and vaginal) have been recently evaluated in the context of cardiovascular disease. This review provides a summary of the association between combined oral contraceptives (COCs) and arterial diseases, with an emphasis on new formulations of hormonal contraceptives, as well as routes of administration. A systematic search of the Medline database was performed to find all relevant articles which included women who had widely use third generation pills, and the development of new progestins. Eligible articles published in English and reporting risk of arterial events (myocardial infarction [MI] and stroke) among users of hormonal contraceptives were reviewed. A quantitative assessment was made from included studies. Overall, current use of oral combined contraceptives increased the risk of MI and ischemic stroke (pooled OR: 1.7; 95% confidence interval [95% CI]: 1.2-2.3 and OR: 1.8; 95% CI: 1.2-2.8, respectively), but this was not associated with the risk of hemorrhagic stroke (OR: 1.1; 95% CI: 0.7-1.9). The increase in ischemic arterial disease was higher among first generation pill users compared with second or third generation pill users. In contrast, risk of ischemic arterial disease among current users of second or third generation pill was similar (p = 0.23 for MI risk and 0.99 for ischemic stroke). In conclusion, newer generation formulations of COCs, as well as the non-oral hormonal contraceptive, do not seem to be safer than second generation hormonal contraceptives.

Abstract
BACKGROUND Oral contraception (OC) and postmenopausal hormone therapy (HT) can be used to alleviate menopausal symptoms. However, the risk of venous thrombosis (VT) associated with OC use in women over 50 years old has never been assessed and the two preparations have not been directly compared. OBJECTIVES To determine and compare the risk of VT associated with OC and HT use. METHODS From a large case-control study, 2550 women aged over 50 years old, 1082 patients with a first VT and 1468 controls, were included. Odds ratios (ORs) and 95% confidence intervals for VT were calculated for OC-users (164 patients and 54 controls) and HT-users (88 patients and 102 controls) compared with non-hormone users (823 patients and 1304 controls). RESULTS OC-users had a 6.3-fold (4.6-9.8) increased risk of VT. This ranged from 5.4 (3.3-8.9) for preparations containing levonorgestrel to 10.2 (4.8-21.7) for desogestrel. The VT-risk associated with oral HT use was 4.0 (1.8-8.2) for conjugated equine estrogen combined with medroxyprogesterone acetate and 3.9 (1.5-10.7) for micronized estradiol combined with norethisterone acetate. Non-oral HT did not increase the risk of VT: OR 1.1 (0.6-1.8). Relative risk estimates were further increased in hormone users with factor V Leiden, prothrombin G20210A or blood group non-O and hormone users with a family history of VT. CONCLUSIONS In this study, non-oral HT seemed to be the safest hormonal preparation in women over 50 years old. OC use increased the VT risk the most, especially in women with inherited thrombophilia or a family history of VT.

Abstract
BACKGROUND Raloxifene use in postmenopausal women with osteoporosis increases the risk of venous thromboembolic events (VTE) 2-fold compared with placebo. Platelet activation is involved in the pathophysiology of arterial thromboses more than venous thromboses, but aspirin may reduce VTE risk associated with estrogen use. This analysis examines the effects of concomitant antiplatelet therapy on VTE risk in raloxifene-treated women. METHODS In the Raloxifene Use for the Heart (RUTH) trial, 10,101 postmenopausal women from 177 sites in 26 countries at increased risk of coronary heart disease (CHD) (primary prevention cohort) or with CHD (secondary prevention cohort) were randomized to placebo or raloxifene 60 mg/day and followed for a median 5.6 years. Reports of clinical symptoms of VTE were assessed. Concomitant use of antiplatelet agents (aspirin, clopidogrel, ticlopidine, dipyridamole) was allowed. Cox proportional hazard models, with use of warfarin, presence of fracture, and hospitalization as covariates, were used to estimate hazard ratios (HR) with 95% confidence intervals (CI). RESULTS Overall, raloxifene use was associated with an increased VTE risk (HR 1.44, 95% CI 1.06-1.95) vs. placebo. Most women (72%) reported using aspirin, and 14.2% reported using nonaspirin antiplatelet agents during the study period. Users of antiplatelet agents were older, more likely to have CHD, and more likely to be hyperlipidemic. They had a higher VTE risk than nonusers. No difference in VTE risk was observed in women who used raloxifene alone vs. those who used raloxifene with antiplatelet agents during the study. The increase in VTE risk with raloxifene compared with placebo was not different between women who used antiplatelet agents at baseline (HR 1.44, 95% CI 0.98, 2.10) and those who did not use antiplatelet agents (HR 1.37, 95% CI 0.83, 2.27) (interaction p = 0.88). Similar conclusions were noted for aspirin and nonaspirin antiplatelet use. CONCLUSIONS In RUTH, postmenopausal women treated with raloxifene had an increased risk of VTE compared with placebo. Concomitant use of aspirin or nonaspirin antiplatelet agents along with raloxifene did not change VTE risk.

Abstract
Obesity, metabolic syndrome, and diabetes are becoming a leading health concern in the developed Countries, due to their link to cardiovascular disease. These conditions are common in women in the post-menopausal period. Unfortunately, actual lifestyle change strategy fail to prevent cardiovascular events for several reasons, thus specific medications are needed. In addition, it was showed an increased cardiovascular diseases and breast cancer risk in postmenopausal women taking estrogens alone or with progestin, thus the optimal therapy for the prevention of chronic disease in women is still lacking. Androgens exert different actions on organs like adipose tissue, brain, bone, and on cardiovascular system. However, a debate still exists on the positive role of androgens on human health, especially in women. Furthermore, the vascular effects of androgens remain poorly understood and have been controversial for a long time. Sex hormones are important determinants of body composition. Aging is, often, accompanied by a decrease in free testosterone levels, a concomitant reduction in muscle mass and an increase in fat mass. Furthermore, numerous studies showed that total serum testosterone levels were inversely related to the atherosclerosis disease incidence in postmenopausal women. New therapeutic targets may, therefore, arise understanding how androgen could influence the fat distribution, the metabolic disease onset, the vascular reactivity and cardiovascular risk, in both sex.

Abstract
Cardiovascular disease is emerging as a cardinal trait of Turner syndrome, being responsible for half of the 3-fold excess mortality. Turner syndrome has been proposed as an independent risk marker for cardiovascular disease that manifests as congenital heart disease, aortic dilation and dissection, valvular heart disease, hypertension, thromboembolism, myocardial infarction, and stroke. Risk stratification is unfortunately not straightforward because risk markers derived from the general population inadequately identify the subset of females with Turner syndrome who will suffer events. A high prevalence of endocrine disorders adds to the complexity, exacerbating cardiovascular prognosis. Mounting knowledge about the prevalence and interplay of cardiovascular and endocrine disease in Turner syndrome is paralleled by improved understanding of the genetics of the X-chromosome in both normal health and disease. At present in Turner syndrome, this is most advanced for the SHOX gene, which partly explains the growth deficit. This review provides an up-to-date condensation of current state-of-the-art knowledge in Turner syndrome, the main focus being cardiovascular morbidity and mortality. The aim is to provide insight into pathogenesis of Turner syndrome with perspectives to advances in the understanding of genetics of the X-chromosome. The review also incorporates important endocrine features, in order to comprehensively explain the cardiovascular phenotype and to highlight how raised attention to endocrinology and genetics is important in the identification and modification of cardiovascular risk.

Abstract
OBJECTIVE Nearly a decade ago, landmark clinical trials revealed an increase in the risks associated with hormone therapy in postmenopausal women, leading to early changes in prescribing patterns. Long-term prescribing patterns in the United States after these trials are unknown. The objective of this study was to describe changes in hormone therapy prescribing including dose, formulation, patient age, and prescriber specialty from 2000 to 2009. METHODS A national pharmacy claims database was used to describe the annual prevalence and incidence rates of hormone therapy prescribing from 2000 to 2009 in women 50 years and older. RESULTS Throughout the decade, a number of prescribing trends were observed: a continuous decline in hormone therapy overall, an initial drop in new therapy that stabilized after 2003, a decline in oral formulations and increase in vaginal formulations, a decline in standard- and high-dose and an increase in low-dose oral formulations, and an increase in the proportion of women who received hormone therapy from gynecologists. CONCLUSIONS Overall prescribing of hormone therapy continued to decline during the past decade, suggesting a long-term impact of the Women's Health Initiative findings. During this same time, treatment regimens shifted to favor vaginal and lower-dose oral formulations.

Abstract
OBJECTIVE The results of the Women's Health Initiative led to a sharp decline in postmenopausal hormone therapy use. Subsequently, treatment guidelines were revised to recommend hormone therapy at the lowest effective dose for the shortest possible duration. The objective of this analysis was to assess trends in nationwide hormone therapy prescription claims from 2002 to 2009. METHODS This study was a retrospective database analyses of pharmacy claims from MedImpact Healthcare Systems Inc. Data from women with claims for oral or transdermal hormone therapy were analyzed to assess trends in hormone therapy claims, including route of administration, dose, and physician specialty. RESULTS By the end of 2002, the total number of hormone therapy claims dropped approximately 30% from 2002 second quarter claims. This trend continued during the next 7 years, and by 2009, hormone therapy claims were reduced by more than 70%. The proportion of low--dose oral claims rose fourfold, whereas the proportion of standard/high-dose claims decreased 30%. The proportion of claims for transdermal formulations more than doubled, and the proportion of claims for low-dose transdermal hormone therapy increased 10-fold. Although reductions in overall claims, routes of administration, and dose categories were similar between physician specialties, obstetrician/gynecologists prescribed transdermal hormone therapy nearly twice as often as all other types of providers. CONCLUSIONS Since the publication of the Women's Health Initiative results, there has been a sustained decrease in hormone therapy claims. The proportional use of low-dose oral and transdermal formulations has increased, but as of 2009, claims for these formulations accounted for approximately one in four total hormone therapy claims.

Abstract
The European Journal of Endocrinology recently published a paper (Asscheman et al.) presenting mortality data from more than a thousand transsexuals followed for a median time of 18 years and who had undergone previous or were currently on long term cross-sex hormonal treatment. Transsexualism is a rare condition and in scientific literature there are few reports on the long-term safety of different treatment protocols and on the physical and psychological outcomes of medical treatments. The safety of long-term high doses oestrogen or testosterone in subjects of the opposite sex has been debated and data on long term effects are scant at best. The Asscherman paper therefore represents a very important and reassuring reference for professionals working in this field suggesting that mortality is increased among transsexuals although due to causes unrelated to cross sex replacement therapy. These results will benefit the care and treatment of these subjects.

Abstract
Turner syndrome (TS), which affects approximately 1 in 2,500 live-born females, is characterized by loss or structural anomalies of an X chromosome. Clinical features vary among patients; multiple organ systems can be affected. Endocrinologists are involved in the management of short stature, delayed puberty, and infertility. Endocrine therapies can include growth hormone, estrogen, and progestogen to promote linear growth and pubertal development. The duration of estrogen and progestogen treatment hormone treatment (HT) is generally more than 40 years. No one standard HT is suitable for all women, so general guidelines are provided to induce pubertal development. Additional considerations regarding HT choice include thrombotic risk and disorders associated with thrombophilia. Involvement of cardiologists is important because approximately 50% of patients with TS have congenital structural cardiac anomalies linked to an increased risk for aortic dissection and rupture. Oocyte donation offers the chance to carry a pregnancy, but accumulating information has highlighted the potential dangers associated with pregnancy. Advances in the care of infants, girls, and women with TS have been achieved; management involves coordinated care from a multidisciplinary team including endocrinologists, cardiologists, geneticists, otolaryngologists, behavioral health experts, nurse educators, and social workers.

Abstract
OBJECTIVE This position statement aimed to update the evidence-based position statement published by The North American Menopause Society (NAMS) in 2010 regarding recommendations for hormone therapy (HT) for postmenopausal women. This updated position statement further distinguishes the emerging differences in the therapeutic benefit-risk ratio between estrogen therapy (ET) and combined estrogen-progestogen therapy (EPT) at various ages and time intervals since menopause onset. METHODS An Advisory Panel of expert clinicians and researchers in the field of women's health was enlisted to review the 2010 NAMS position statement, evaluate new evidence, and reach consensus on recommendations. The Panel's recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. RESULTS Current evidence supports the use of HT for perimenopausal and postmenopausal women when the balance of potential benefits and risks is favorable for the individual woman. This position statement reviews the effects of ET and EPT on many aspects of women's health and recognizes the greater safety profile associated with ET. CONCLUSIONS Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms and to prevent osteoporosis in women at high risk of fracture. The more favorable benefit-risk ratio for ET allows more flexibility in extending the duration of use compared with EPT, where the earlier appearance of increased breast cancer risk precludes a recommendation for use beyond 3 to 5 years.

Abstract
The perceptions of menopausal hormone therapy (MHT) have evolved considerably. Observational studies suggested that MHT could relieve vasomotor symptoms and prevent coronary heart disease (CHD). However, randomized controlled trials later showed no reduction in CHD and an increased risk of stroke. Subsequent analyses of these trials have shown that in women younger and closer to menopause, the risks associated with MHT may not be as great as originally thought. Several organizations, including the North American Menopause Society, the International Menopause Society, and the Endocrine Society, have published guidelines and statements that help health care providers translate the research findings into clinical practice. A common theme from these organizations is the need for health care providers to tailor information to their patients so they may make informed treatment decisions (especially considering the media attention MHT has received). It is particularly important to individualize therapy, considering patients’ risk factors for atherosclerotic disease, venous thromboembolic disease, osteoporosis, and breast cancer. Ongoing research in women younger than those in prior trials is evaluating lower doses of MHT and directly comparing transdermal and oral formulations. Such research should help define the population of women most likely to benefit from MHT without undue risk of adverse outcomes.

Abstract
During the transition into menopause, women may experience a wide range of symptoms that negatively impact quality of life. The vasomotor symptoms (VMS) of hot flushes and night sweats are common and vary widely in frequency and severity. The treatment of menopause-associated VMS is a frequently encountered clinical challenge, with the goal of tailoring treatment for each individual woman's needs. Estrogen therapy is the most effective treatment for menopausal VMS. Current guidelines suggest that estrogen therapy be prescribed at the lowest effective dose for the shortest duration of time. Transdermal estrogen therapy has dominated the menopause prescribing practice in Europe for decades; however, in the United States, oral estrogen therapy is most commonly prescribed. Transdermal estrogen therapy can be prescribed at considerably lower doses than oral therapy yet has similar efficacy on the symptoms of menopause. Emerging research demonstrates transdermal estrogen, particularly 17beta-estradiol, may have the potential for fewer health risks than oral estrogen therapy. This review article discusses the spectrum of menopausal symptoms, addresses prevailing issues in the treatment of menopause, elaborates on the risks and benefits of oral and transdermal hormone therapies, and focuses on five nonpatch transdermal estradiol therapies currently available in the United States.

Abstract
The cardiovascular effects of hormone replacement therapy (HRT) have been the subject of much debate since the initial findings from the Women's Health Initiative (WHI) were reported. However, re-analyses of WHI results have suggested that the association between HRT use and cardiovascular risk is influenced by several factors and that, among these, age and time since menopause may play a key role. Preclinical and human studies have shown differential effects of estrogen on the vasculature of healthy subjects compared with those with existing atherosclerosis. Indeed, while HRT has shown no protective effects in the presence of established atherosclerotic disease, it may have beneficial or neutral effects on healthy vasculature or early atherosclerosis. However, the final cardiovascular effects of estrogens in non-hysterectomized women are influenced by the type, dosage, and route of administration of the progestin used in association. The results of ongoing studies on the timing of HRT initiation will help women make better informed decisions regarding their menopausal health. Current treatment guidelines recommend initiation of HRT in recently postmenopausal women for the relief of vasomotor symptoms.

Abstract
This article presents an up-to-date review of the literature on hormone augmentation in the elderly to help primary care physicians better evaluate and utilize hormone replacement and optimization strategies to benefit their patients. The scientific literature suggests that hormone supplementation with estrogen, progesterone, testosterone, growth hormone, and thyroid hormone has the potential to improve quality of life and to prevent, or reverse, the many symptoms and conditions associated with aging, including fatigue, depression, weight gain,frailty, osteoporosis, loss of libido, and heart disease. Possible long-term side effects are also considered.

Abstract
Much new information on menopausal hormone therapy (MHT) has become available since the publication of the first report of the Women's Health Initiative in 2002 and a consensus is now emerging. The risk of breast cancer depends on type of MHT, duration of use, body mass, breast density and interval between menopause and starting MHT. The risk of breast cancer is generally increased by MHT, particularly in lean women with no previous MHT who start estrogen–progestin therapy near the menopause and continue for several years, but there is no increased risk 5 years after stopping MHT. The risks of venous thrombo-embolic disease (VTE), stroke and coronary heart disease (CHD) depend on age on starting MHT, dose, nature and route of administration of MHT. The risk of VTE is increased in women over 60 years of age and in women who are obese or have had a VTE but may not be increased by transdermal estrogens. The risk of stroke is very small in women under 60 years of age and may not be increased by low dose oral and low dose transdermal estrogen, MHT is of benefit in preventing atherosclerosis and CHD in healthy younger postmenopausal women (under the age of 60) but is not of benefit, and may be harmful, in older women with clinical or subclinical atherosclerosis. MHT prevents bone loss and osteoporosis but is not generally recommended in women over 60 because of the risks of VTE, stroke and CHD, and if stopped at 60 years does not prevent fractures in later life. MHT reduces the overall mortality in women under 60. MHT is by far the most effective treatment, and greatly improves the quality of life in women with menopausal symptoms. A simplified approach to MHT is suggested as a framework for the care of women at and after the menopause.

Abstract
OBJECTIVE The aim of this study was to quantify the magnitude of risk reduction for venous thromboembolism events associated with an estradiol transdermal system relative to oral estrogen-only hormone therapy agents. METHODS A claims analysis was conducted using the Thomson Reuters MarketScan database from January 2002 to October 2009. Participants 35 years or older who were newly using an estradiol transdermal system or an oral estrogen-only hormone therapy with two or more dispensings were analyzed. Venous thromboembolism was defined as one or more diagnosis codes for deep vein thrombosis or pulmonary embolism. Cohorts of estradiol transdermal system and oral estrogen-only hormone therapy were matched 1:1 based on both exact factor and propensity score matching, and an incidence rate ratio was used to compare the rates of venous thromboembolism between the matched cohorts. Remaining baseline imbalances from matching were included as covariates in multivariate adjustments. RESULTS Among the matched estradiol transdermal system and oral estrogen-only hormone therapy users (27,018 women in each group), the mean age of the cohorts was 48.9 years; in each cohort, 6,044 (22.4%) and 1,788 (6.6%) participants had a hysterectomy and an oophorectomy at baseline, respectively. A total of 115 estradiol transdermal system users developed venous thromboembolism, compared with 164 women in the estrogen-only hormone therapy cohort (unadjusted incidence rate ratio, 0.72; 95% CI, 0.57-0.91; P = 0.006). After adjustment for confounding factors, the incidence of venous thromboembolism remained significantly lower for estradiol transdermal system users than for estrogen-only hormone therapy users. CONCLUSIONS This large population-based study suggests that participants receiving an estradiol transdermal system have a significantly lower incidence of venous thromboembolism than do participants receiving oral estrogen-only hormone therapy.

Abstract
Obesity has emerged as a global health issue that is associated with wide spectrum of disorders, including coronary artery disease, diabetes mellitus, hypertension, stroke, and venous thromboembolism (VTE). VTE is one of the most common vascular disorders in the United States and Europe and is associated with significant mortality. Although the association between obesity and VTE appears to be moderate, obesity can interact with other environmental or genetic factors and pose a significantly greater risk of VTE among individuals who are obese and who are exposed simultaneously to several other risk factors for VTE. Therefore, identification of potential interactions between obesity and certain VTE risk factors might offer some critical points for VTE interventions and thus minimize VTE morbidity and mortality among patients who are obese. However, current obesity measurements have limitations and can introduce contradictory results in the outcome of obesity. To overcome these limitations, this review proposes several future directions and suggests some avenues for prevention of VTE associated with obesity as well.

Abstract
Prevention of cardiovascular disease has increasingly important health implications as our population ages. Menopause is associated with the development of cardiovascular risk factors and there are many plausible biological mechanisms through which estrogen may confer cardiovascular protection. Despite a wealth of observational data to support the use of estrogen, large randomized controlled trials failed to demonstrate a benefit. It is now becoming clearer that the beneficial cardiovascular effects of estrogen are greatest in younger women and those closest to menopause. This has led to the development of the timing hypothesis. Use of age-appropriate estrogen doses is crucial to maximize cardiovascular benefits while minimizing risk of adverse effects such as venous thromboembolism and stroke.

Abstract
For many years, hormone replacement therapy (HRT) was the mainstay for osteoporosis prevention in postmenopausal women until a large randomized clinical trial raised serious safety concerns. This resulted in a big drop in HRT use and its demotion by regulatory authorities to second-line treatment. Many clinicians now feel that HRT is not safe to use, and recommend various alternatives for the treatment of osteoporosis. But how effective are these alternative therapies, are they any safer than HRT, and how do their costs compare? This review questions the validity of the safety concerns about HRT, and highlights the safety concerns about alternative therapies. It concludes that HRT is as safe as the other treatment options, and its efficacy and low cost demand that it be restored as a first-line treatment for the prevention of postmenopausal osteoporosis. Other therapies are available for use in osteoporosis, and the bisphosphonates are particularly effective for the treatment of the established disease. However, they must be used selectively and with caution, and are best restricted to those patients who are elderly or have severe disease. New treatments are emerging, but again caution must be taken until any long-term adverse effects have been identified.

Abstract
Statins, among the most commonly prescribed drugs worldwide, are cholesterol-lowering agents used to manage and prevent cardiovascular and coronary heart diseases. Recently, a multifaceted action in different physiological and pathological conditions has been also proposed for statins, beyond anti-inflammation and neuroprotection. Statins have been shown to act through cholesterol-dependent and -independent mechanisms and are able to affect several tissue functions and modulate specific signal transduction pathways that could account for statin pleiotropic effects. Typically, statins are prescribed in middle-aged or elderly patients in a therapeutic regimen covering a long life span during which metabolic processes, aging, and concomitant novel diseases, including cancer, could occur. In this context, safety, toxicity, interaction with other drugs, and the state of health have to be taken into account in subjects treated with statins. Some evidence has shown a dichotomous effect of statins with either cancer-inhibiting or -promoting effects. To date, clinical trials failed to demonstrate a reduced cancer occurrence in statin users and no sufficient data are available to define the long-term effects of statin use over a period of 10 years. Moreover, results from clinical trials performed to evaluate the therapeutic efficacy of statins in cancer did not suggest statin use as chemotherapeutic or adjuvant agents. Here, we reviewed the pharmacology of the statins, providing a comprehensive update of the current knowledge of their effects on tissues, biological processes, and pathological conditions, and we dissected the disappointing evidence on the possible future use of statin-based drugs in cancer therapy.
