The bioidentical hormone debate: are bioidentical hormones (estradiol, estriol, and progesterone) safer or more efficacious than commonly used synthetic versions in hormone replacement therapy?

Background: The use of bioidentical hormones, including progesterone, estradiol, and estriol, in hormone replacement therapy (HRT) has sparked intense debate. Of special concern is their relative safety compared with traditional synthetic and animal-derived versions, such as conjugated equine estrogens (CEE), medroxyprogesterone acetate (MPA), and other synthetic progestins. Proponents for bioidentical hormones claim that they are safer than comparable synthetic and nonhuman versions of HRT. Yet according to the US Food and Drug Administration and The Endocrine Society, there is little or no evidence to support claims that bioidentical hormones are safer or more effective. Objective: This paper aimed to evaluate the evidence comparing bioidentical hormones, including progesterone, estradiol, and estriol, with the commonly used nonbioidentical versions of HRT for clinical efficacy, physiologic actions on breast tissue, and risks for breast cancer and cardiovascular disease. Methods: Published papers were identified from PubMed/MEDLINE, Google Scholar, and Cochrane databases, which included keywords associated with bioidentical hormones, synthetic hormones, and HRT. Papers that compared the effects of bioidentical and synthetic hormones, including clinical outcomes and in vitro results, were selected. Results: Patients report greater satisfaction with HRTs that contain progesterone compared with those that contain a synthetic progestin. Bioidentical hormones have some distinctly different, potentially opposite, physiological effects compared with their synthetic counterparts, which have different chemical structures. Both physiological and clinical data have indicated that progesterone is associated with a diminished risk for breast cancer, compared with the increased risk associated with synthetic progestins. Estriol has some unique physiological effects, which differentiate it from estradiol, estrone, and CEE. Estriol would be expected to carry less risk for breast cancer, although no randomized controlled trials have been documented. Synthetic progestins have a variety of negative cardiovascular effects, which may be avoided with progesterone. Conclusion: Physiological data and clinical outcomes demonstrate that bioidentical hormones are associated with lower risks, including the risk of breast cancer and cardiovascular disease, and are more efficacious than their synthetic and animalderived counterparts. Until evidence is found to the contrary, bioidentical hormones remain the preferred method of HRT. Further randomized controlled trials are needed to delineate these differences more clearly.

Hyperandrogenic manifestation in women, such as seborrhea, acne and increased hair growth are common reasons of psychological distress. Skin appearance is very important for young women. This study evaluated the hormonal and skin effects of two estroprogestins (EPs) containing ethinyl-estradiol (EE) 30 microg associated with drospirenone (DRSP) 3 mg or chlormadinone acetate (CMA) 2 mg, respectively. Fifty-five women with signs and symptoms of hyperandrogenism (seborrhea, acne and increased hair growth) were enrolled in the study; randomly, 30 women were treated with EE 30 microg + DRSP 3 mg and 25 with EE 30 microg + CMA 2 mg. Follicle-stimulating hormone (FSH), luteinising hormone (LH), 17-hydroxyprogesterone (17OHP), androstenedione (A), testosterone (T), dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG) and free androgen index (T x 100/SHBG, FAI) were assessed at baseline, and after 3 and 6 months of treatment with EPs. Effects on seborrhea, acne and increased hair growth (as Ferriman-Gallwey score) were also evaluated at the same time points. Finally, skin hydration, transepidermal water loss (TEWL) and skin homogeneity were studied with non-invasive technique during the study. Treatment for 6 months with both EPs decreased significantly the circulating androgen levels (A, T, DHEAS) and FAI, and increased SHBG levels; also skin pattern was improved. EP containing EE and DRSP was better than EP containing EE and CMA as for skin changes, as seborrhea, acne, increased hair, hydration, homogeneity and overall quality of the skin; moreover, hormonal changes (as FAI) under therapy were more pronounced with EE/DRSP than EE/CMA. These effects may be considered in EP choice and could be important in improving patient's compliance and quality of life in hyperandrogenic women.

OBJECTIVE: To determine the morbidity incidence associated with Hormone Replacement Therapy (HRTs) in postmenopausal women. This paper presents the results concerning the incidence of coronary heart disease (CHD). DESIGN: MISSION study started on 5 January 2004, the cutoff for data collection was June 2006 (follow-up no. 1). 'Exposed group': postmenopausal women currently on HRT, commonly prescribed in France or stopped < or =5 years previously. 'Unexposed group': never received HRT or stopped >5 years previously. RESULTS: Data were available for 4949 patients (without CHD at the beginning of the follow-up): 2693 Exposed group and 2256 Unexposed group. The incidence during follow-up no. 1 of postmenopausal CHD was not significantly different in the Exposed group (0.11%) compared with the Unexposed group (0.13%). In the Exposed group the time between start of HRT and menopause was 2.93 +/- 4.46 years in those who experienced CHD and 1.53 +/- 3.20 years in those who had no incidence of CHD (p = 0.3). CONCLUSION: In the MISSION cohort, no increased risk of CHD was found in the Exposed group compared with the Unexposed group.

AIM: To evaluate with validated instruments changes in quality of life and sexuality in women receiving hormonal replacement therapy (AHT). DESIGN: Randomised, double-blind, double-dummy study with two parallel treatment arms. PATIENTS AND METHODS: Forty-seven healthy post-menopausal women, aged 45-64 years, were evaluated using the Female Sexual Function Index (FSFI) and the menopause-specific quality of life questionnaire (MENQOL). Of them, 40 diagnosed with sexual dysfunction were randomised (1:1) to receive daily 0.625 mg of conjugated estrogens plus 1.25 mg of methyl-testosterone and 100 mg of micronised progesterone or placebo. After 3 months follow-up, FSFI and MENQOL questionnaires were administered for a second time. RESULTS: Quality of life was unchanged in the placebo group whereas AHT significantly improved scores of vasomotor, psychological, physical and sexual symptoms. As expected, FSFI was not modified in the placebo group while in AHT group the FSFI score improved significantly. In addition, at the end of the study, 68.7% of subjects of the AHT group did not fit did not fit the criteria for sexual dysfunction as per the FSFI (p < 0.0001). CONCLUSIONS: Adding methyl-testosterone to hormone therapy improves quality of life and sexuality in post-menopausal women with sexual dysfunction.

BACKGROUND: The relationship of loop diuretics to bone mineral density (BMD), falls, and fractures in postmenopausal women has not been established. METHODS: We examined whether loop diuretics are associated with changes in BMD, falls, and fractures in women enrolled in the Women's Health Initiative. We included the 133,855 women (3411 users and 130,444 nonusers of loop diuretics) who were enrolled in the WHI from October 29, 1993 to December 31, 1998 and determined incident falls and fractures for a mean of 7.7 years. Women who had BMD measurements at baseline and at year 3 (300 users and 9124 nonusers of loop diuretics) were also examined. RESULTS: After adjustment for covariates, no significant association was found between ever use of loop diuretics and total (hazard ratio [HR], 1.09; 95% confidence interval [CI], 1.00-1.19), hip (HR, 1.21; 95% CI, 0.91-1.60), and clinical vertebral fractures (HR, 1.17; 95% CI, 0.92-1.48) and falls (1.02; 0.96-1.08). An increased risk was found for other clinical fractures (1.16; 1.01-133) and total fractures (1.16; 1.03-1.31) with more than 3 years' use of loop diuretics. The BMD changes were not associated with loop diuretic use. CONCLUSIONS: After adjustment for confounding variables, no significant association was found between ever use of loop diuretics and changes in BMD, falls, and fractures. Loop diuretics were used by women in poor health who were already at risk for fractures. However, prolonged use of loop diuretics was associated with higher fracture risk in postmenopausal women.

The objectives of this study were to determine the incidence of and associated risks for falls and fractures after gastric bypass surgery for morbid obesity and to determine the clinical signs of bone loss. The sample consisted of 167 individuals at a mean age of 47 years (SD = 10). Ten participants (6%) reported a decrease in height since surgery, and 33 (20%) reported a decrease in height since they were 20 years old. Eight participants (5%) reported postoperative fractures. Twenty-three participants (13.8%) reported falling once since surgery, and 34 (20.4%) reported falling two or more times since surgery. Twelve participants reported a new diagnosis of osteoporosis postoperatively, and 1 participant reported a new diagnosis of osteopenia. Sixty-seven percent (n = 112) of the participants were never advised to undergo a bone density test postoperatively. The findings from this study suggest that bone loss is a critical issue in this patient population, with 25% (n = 42) reporting a decrease in height, 8% (n = 13) reporting a new diagnosis of osteoporosis or osteopenia, and 5% (n = 8) reporting fractures during a mean postoperative interval of 2.4 years. In addition, risk for skeletal fragility is profound in this cohort of individuals, with 34% (n = 57) indicating a history of one or more falls postoperatively. The results from this study clearly indicate a need for early recognition of bone loss in this population so that timely interventions can be initiated to prevent further loss and subsequent fractures.

INTRODUCTION: Transdermal testosterone patch (TTP) treatment produced statistically significant improvements in a satisfying sexual activity (SSA), sexual desire, and personal distress in postmenopausal women suffering from hypoactive sexual desire disorder (HSDD), but clinical significance of these changes was not determined. AIM: To quantify the magnitude of change in three principal outcomes measures determined by HSDD patients as associated with the perception of meaningful benefit with TTP therapy. METHODS: The criteria for defining responders were determined using anchoring methodology and receiver operating characteristics analysis to establish minimum important differences (MIDs) in a representative subsample of 132 patients in two randomized, controlled trials in surgically menopausal women with HSDD (N = 1,094). Perceived benefit was established based upon the question "Overall, would you say that you experienced a meaningful benefit from the study patches?". These data defined responders and established MIDs for changes in sexual desire, SSA, and personal distress. The MIDs were applied to the two trials to establish responder rates in each treatment group. MAIN OUTCOME MEASURES: Changes in score that correspond to the MID for sexual desire, SSA, and personal distress, and responder rates in each treatment group based upon these values. RESULTS: Increases in frequency of SSA of greater than 1 activity/4 weeks, increases in sexual desire score of > or = 8.9, and decreases in the personal distress score of > or = 20.0 were identified as threshold improvements best able to differentiate responders and nonresponders. The responder rate was significantly higher (P < 0.001) in the testosterone group vs. placebo for all three outcomes measures (sexual desire, 50% vs. 34%; SSA, 44% vs. 30%; personal distress, 51% vs. 39%). CONCLUSIONS: Changes in sexual desire, SSA, and personal distress observed with TTP treatment in surgically menopausal women with HSDD were clinically significant and were associated with a meaningful treatment benefit.

INTRODUCTION: The sexual response depends on the adequate function of all systems related to the genital and extra-genital organs. Physiological conditions such as menopause can interfere with sexual expression because of central and peripheral changes. Genital effects of estrogen include vaginal trophism, lubrication, and local pleasure sensation in the sexual arousal phase. Hypoestrogenism causes changes in the four layers of the vaginal wall that may result in dyspareunia and a loss in the quality of the genital arousal response. AIM: The purpose of this review is to highlight the changes in the vaginal wall caused by hypoestrogenism, its possible relationship with dyspareunia, and its repercussions for genital arousal. Treatments for hypoestrogenism are also discussed. METHODS: We evaluated the data available in PubMed (1982-2008) and surveyed the reference list for relevant studies. Two reviewers analyzed the data independently. A study was considered to be of high quality if it had all three of the following characteristics: (i) prospective design; (ii) valid data; and (iii) adequate sample size. Reviews and experimental animal studies were also considered. MAIN OUTCOME MEASURES: Normal genital morphology, hypoestrogenism and hormone replacement therapy were the focus of the studies reviewed in this paper. RESULTS: Atrophy of the vaginal wall may be associated with dyspareunia and genital sexual arousal disorder, but psychological and sociocultural aspects must also be considered. Regardless, however, local estrogen therapy is useful in improving vaginal wall trophism and, thus, in improving the sexual response. CONCLUSIONS: There are many possible alterations in the structure of the vaginal wall that are related to estrogen deficiency that may require medical intervention beyond the usual strategies used to attain adequate sexual function. Physicians should attempt to treat these alterations, and more research is needed to elucidate the physiopathology of dyspareunia and genital sexual arousal physiology.

Testosterone replacement therapy in naturally and surgically menopausal women.

Panzer C, Guay A.

Rose Medical Center-Department of Endocrinology, Denver, Colorado, USA.

INTRODUCTION: Testosterone replacement therapy in naturally and surgically menopausal women is a complex and currently highly debated topic. Opposing guidelines for the use of testosterone exist, which create a therapeutic dilemma for clinicians confronted by severely distressed women who experience a decrease in sexual desire after surgical or natural menopause. AIM: In this review, we will address the current knowledge on androgen physiology, conditions associated with a low androgen state, and risks and benefits of androgen therapy. METHODS: An English-language Medline review was performed. MAIN OUTCOME MEASURE: Review of available literature. RESULTS: A review of normal androgen physiology in women is summarized and a brief review of prior use of androgens over the last six decades is included. The data on the use of androgen replacement in pre- and postmenopausal women is evaluated, especially its relationship to sexual functioning. Special concerns about the effect of androgens on cardiovascular disease, breast, and endometrial tissue are discussed. The balance of evidence seems to show that androgens have more of a positive effect than a negative effect in women if used properly. CONCLUSIONS: Testosterone replacement therapy for surgically and naturally menopausal women with low sexual desire can be accomplished physiologically and effectively after ruling out other medical conditions leading to low sexual desire and after proper information of the patient that testosterone therapy is not an FDA-approved medication in the United States. The majority of available data suggests that testosterone replacement in women can be used safely without increased risk of endometrial or breast cancer.

Age-specific symptom prevalence in women 35-64 years old . A population-based study.

Bardel A, Wallander MA, Wedel H, Svardsudd K.

ABSTRACT: BACKGROUND: Symptom prevalence is generally believed to increase with age. The aim of this study was to evaluate the age specific prevalence of 30 general symptoms among Swedish middle-aged women. METHODS: A cross-sectional postal questionnaire study in seven Swedish counties in a random sample of 4,200 women 35-64 years old, with 2,991 responders. Thirty general symptoms included in the Complaint Score subscale of the Gothenburg Quality of Life Instrument were used. RESULTS: Four groups of age specific prevalence patterns were identified after adjustment for the influence of educational level, perceived health and mood, body mass index, smoking habits, use of hormone replacement therapy, and use of other symptom relieving therapy. Only five symptoms (insomnia, leg pain, joint pain, eye problems and impaired hearing) increased significantly with age. Eleven symptoms (general fatigue, headache, irritability, melancholy, backache, exhaustion, feels cold, cries easily, abdominal pain, dizziness, and nausea) decreased significantly with age. Two symptoms (sweating and impaired concentration) had a biphasic course with a significant increase followed by a significant decrease. The remaining twelve symptoms (difficulty in relaxing, restlessness, overweight, coughing, breathlessness, diarrhoea, chest pain, constipation, nervousness, poor appetite, weight loss, and difficulty in urinating) had stable prevalence with age. CONCLUSIONS: Symptoms did not necessarily increase with age instead symptoms related to stress-tension-depression decreased.

OBJECTIVE:: The aim of this study was to investigate the role of vasomotor and mood symptoms on insomnia in postmenopausal women. METHODS:: One hundred sixty-three postmenopausal women, not receiving hormone therapy, attending a menopause clinic at the University of Athens, Greece, were included in this cross-sectional study. Climacteric symptoms were assessed by Greene's scale, whereas psychological morbidity was measured by Zung Self-Assessment Depression Scale, Symptom Checklist-90-R, and Athens Insomnia Scale. RESULTS:: Vasomotor symptoms were significantly associated with insomnia (P = 0.001). When depressive symptomatology was added to the logistic regression analysis, the predictive ability of the model was significantly improved as defined by the increase in the log likelihood (P < 0.001) and the increase in the area under the receiver operating characteristic curve. CONCLUSIONS:: Insomnia in postmenopausal women attending a menopause clinic is related both to the effects of vasomotor symptoms and depressive symptomatology. Mood symptoms seem to affect sleep independently of vasomotor symptoms, suggesting that depression should be carefully assessed and treated in postmenopausal women with insomnia.

A prospective study of the association between endogenous hormones and depressive symptoms in postmenopausal women.

Ryan J, Burger HG, Szoeke C, Lehert P, Ancelin ML, Dennerstein L.

From 1The University of Melbourne, Parkville, Victoria, Australia; 2Inserm U888, Montpellier, F-34093 France; 3University of Montpellier, Montpellier, F-34000 France; 4Prince Henry's Institute of Medical Research, Clayton, Victoria, Australia; and 5University of Mons, Belgium.

OBJECTIVE:: Across a woman's lifetime, variations in hormone levels are known to influence mood and well-being. Whether absolute or changes in hormone levels over time are associated with depression among postmenopausal women remains unclear. METHODS:: The Melbourne Women's Midlife Health Project is a longitudinal population-based study of women who were followed through the menopausal transition. This analysis is based on data collected from 138 postmenopausal women in years 11 and 13 of the study, who were assessed for the presence of depressive symptoms using the Center for Epidemiological Studies Depression Scale. Logistic regression models were developed to determine whether absolute or changes in hormone levels were associated with depression. RESULTS:: No significant associations were found between depressive symptoms and the absolute levels of sex hormone-binding globulin, testosterone, free androgen index, estradiol, free estradiol, or follicle-stimulating hormone (FSH). On the other hand, women with a decline in total serum estradiol over the 2-year period had a more than threefold increased risk of depressive symptoms (odds ratio, 3.5; 95% CI, 1.2-9.9). A large increase in FSH levels over this period was also associated with depressive symptoms (odds ratio, 2.6; 95% CI, 1.0-6.7). These associations remained even after adjustment for initial depression score, as well as a range of potential confounding factors. CONCLUSIONS:: Changes in estradiol and, to a lesser extent, in FSH levels are associated with an increased risk of depressive symptoms in postmenopausal women. These results further support a role for fluctuating rather than absolute hormone levels in depression in later life.

Division of Female Endocrinology and Andrology, Endocrinology Sector, Hospital da Lagoa, Instituto Fernandes Figueira, Fiocruz, Rio de Janeiro, RJ, Brazil.

OBJECTIVE: To analyze the relative risk of late-onset hypogonadism in men with osteoporosis and the usefulness of screening questionnaires. METHODS: We correlated the Aging Male's Symptoms (AMS), Androgen Deficiency in Aging Male (ADAM) and International Index of Erectile Function (IIEF-5) questionnaires and the laboratory diagnosis of hypogonadism in 216 men aged 50-84 years (110 with osteoporosis and 106 with normal bone density, paired by age and ethnicity). RESULTS: Hypogonadism presented in 25% of the osteoporotic and in 12.2 % of normal bone density men (OR 2.08; IC95%: 1.14-3.79) and was associated with ADAM first question (low libido, p=0.013). Levels of TT below 400 ng/dl correlated with an AMS score above 26 (p=0.0278). IIEF-5 showed no correlation with testosterone levels. CONCLUSION: Hypogonadism was 2.08 times more prevalent in osteoporotic men. The symptom that best correlated with late-onset hypogonadism was low libido (ADAM 1 positive).

Is the immunological noise of abnormal autoimmunity an independent risk factor for premature ovarian aging?

Gleicher N, Weghofer A, Oktay K, Barad DH.

OBJECTIVE:: The risk for premature ovarian failure increases in association with two principal known etiologies: in the presence of excessive triple CGG expansions on the FMR1 (fragile X) gene (genetic etiology) and in association with a variety of autoimmune conditions (autoimmune etiology). To what degree milder forms of premature ovarian aging are also associated with these two etiologies is, however, unknown. METHODS:: We, therefore, investigated 119 consecutive, so identified, infertile women and statistically correlated by linear and logistic regression analyses ovarian function parameters to markers of a possible genetic etiology (number of CGG triple repeats on the FMR1 gene) and to markers of possible abnormal immune function (immune panel). RESULTS:: Sixty (50.4%) of 119 participants demonstrated at least one immune abnormality. Both groups did not differ statistically in age, mean follicle-stimulating hormone, estradiol, and antimüllerian hormone levels, although antimüllerian hormone suggested a trend toward higher levels in autoimmune participants (P = 0.19). Autoimmune participants also demonstrated lower mean triple CGG expansion sizes (P < 0.05) and included fewer women with greater than or equal to 35 triple repeats (relative risk, 4.0; 95% CI, 1.3-11.9; P < 0.01), previously reported to demarcate increased risk for premature ovarian aging. CONCLUSIONS:: Even minimal evidence of abnormal autoimmune function ("immunological noise") seems to increase risk toward premature ovarian aging, often manifesting as infertility. Evidence of abnormal autoimmune function, such as increased CGG triple expansion sizes, in young women, therefore, warrants vigilance for development of prematurely diminished ovarian reserve and infertility.

BACKGROUND: Following the release of the 2002 report of the Women's Health Initiative (WHI) trial of estrogen plus progestin, the use of menopausal hormone therapy in the United States decreased substantially. Subsequently, the incidence of breast cancer also dropped, suggesting a cause-and-effect relation between hormone treatment and breast cancer. However, the cause of this decrease remains controversial. METHODS: We analyzed the results of the WHI randomized clinical trial--in which one study group received 0.625 mg of conjugated equine estrogens plus 2.5 mg of medroxyprogesterone acetate daily and another group received placebo--and examined temporal trends in breast-cancer diagnoses in the WHI observational-study cohort. Risk factors for breast cancer, frequency of mammography, and time-specific incidence of breast cancer were assessed in relation to combined hormone use. RESULTS: In the clinical trial, there were fewer breast-cancer diagnoses in the group receiving estrogen plus progestin than in the placebo group in the initial 2 years of the study, but the number of diagnoses increased over the course of the 5.6-year intervention period. The elevated risk decreased rapidly after both groups stopped taking the study pills, despite a similar frequency of mammography. In the observational study, the incidence of breast cancer was initially about two times as high in the group receiving menopausal hormones as in the placebo group, but this difference in incidence decreased rapidly in about 2 years, coinciding with year-to-year reductions in combined hormone use. During this period, differences in the frequency of mammography between the two groups were unchanged. CONCLUSIONS: The increased risk of breast cancer associated with the use of estrogen plus progestin declined markedly soon after discontinuation of combined hormone therapy and was unrelated to changes in frequency of mammography.

Angeliq versus Activelle in normotensive postmenopausal women: a prospective, randomized pilot study.

Battaglia C, Cianciosi A, Mancini F, Persico N, Sisti G, Facchinetti F, Busacchi P.

From the 1Department of Obstetrics and Gynecology, Alma Mater Studiorum, University of Bologna, Bologna, Italy; and 2Department of Obstetrics and Gynecology, University of Modena and Reggio Emilia, Modena, Italy.

OBJECTIVE:: The aim of this study was to compare, in normotensive postmenopausal women, the effects of drospirenone/estradiol and norethisterone acetate/estradiol on blood pressure and other surrogate markers of cerebrovascular and cardiovascular risk. METHODS:: Thirty postmenopausal women were submitted to utero-ovarian ultrasonography and to color Doppler evaluation of ophthalmic arteries. Ultrasonographic and Doppler analysis of brachial artery flow-mediated vasodilatation and 24-hour ambulatory blood pressure monitoring were performed. Plasma concentrations of nitrites/nitrates were assayed. The participants were randomly assigned to drospirenone 2 mg/estradiol 1 mg (group 1; n = 15) or norethisterone acetate 0.5 mg/estradiol 1 mg (group 2; n = 15) treatment. The duration of the study was 6 months. RESULTS:: The basal pulsatility index and the back pressure of the ophthalmic artery were similar in groups 1 and 2. After 6 months, no changes were observed. The nitrites/nitrates values were not different between groups 1 and 2 both in basal conditions and after therapy. The brachial artery flow-mediated vasodilatation and the pulsatility index of the brachial artery did not show any difference in groups 1 and 2 both in basal conditions and after the therapy. The 24-hour blood pressure monitoring showed no significant differences in the 24-hour time, daytime, and nighttime values either in basal conditions or after therapy. All participants were found to be dippers normally (nocturnal reduction >/=10% in comparison with diurnal values). The wake-up blood pressure values were similar in the studied participants. CONCLUSIONS:: A 6-month hormone therapy with drospirenone/estradiol or norethisterone acetate/estradiol is equally effective and does not seem to alter the surrogate markers of cardiovascular and cerebrovascular risk.

Hypoactive Sexual Desire Disorder in Postmenopausal Women: Quality of Life and Health Burden.

Biddle AK, West SL, D'Aloisio AA, Wheeler SB, Borisov NN, Thorp J.

Department of Health Policy and Management, Gillings, School of Global Public Health, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

ABSTRACT Objectives: To describe the health-related quality of life (HRQOL) implications of hypoactive sexual desire disorder (HSDD) in a national sample of postmenopausal women ages 30-70. Methods: The Nationwide Survey of Female Sexual Health, a random-digit telephone survey of US households, collected information on female sexual function, demographic characteristics, HRQOL, and the presence of specific medical disorders from 1189 naturally or surgically postmenopausal women in stable relationships of >/=3 months duration. HSDD was defined as <40 on the Profile of Female Sexual Function((c)) scale and <60 on the Personal Distress Scale((c)). Short Form-12 Health Survey (SF-12) summary and domain scores, and EuroQol (EQ-5D) index score and dimensions were compared with population-based norms for healthy individuals and selected chronic conditions. Results: HSDD was associated with significant HRQOL decrements, with the largest SF-12 score differences in mental health (HSDD: 45.4 [standard error 1.9] vs. no HSDD: 51.0 [0.6], P < 0.01), vitality (HSDD: 47.7 [1.3] vs. no HSDD: 52.0 [0.7], P < 0.01), social function (HSDD: 47.3 [1.4] vs. no HSDD: 50.9 [0.7], P < 0.05), and bodily pain (HSDD: 41.4 [2.2] vs. no HSDD: 46.7 [0.9], P < 0.05). EQ-5D index was 0.08 points lower (HSDD: 0.76 [0.03] vs. no HSDD: 0.84 [0.02], P < 0.05) for those with HSDD compared with those without. HSDD was associated with a 0.1-point decrement in naturally menopausal women (HSDD: 0.78 [0.03] vs. no HSDD 0.88 [0.01], P < 0.01). Women with HSDD showed more HRQOL impairment than healthy population norms but were similar to adults with other chronic conditions such as diabetes and back pain. Conclusions: Women with HSDD showed substantial impairment in HRQOL. Given a prevalence of 6.6% to 12.5% among US women, HSDD represents an important burden on quality of life.

Duration of vasomotor symptoms in middle-aged women: a longitudinal study.

Col NF, Guthrie JR, Politi M, Dennerstein L.

From the 1Center for Outcomes Research and Evaluation, Maine Medical Center, Portland, ME; 2Office for Gender and Health, Department of Psychiatry, The University of Melbourne, Victoria, Australia; and 3Department of Behavioral and Preventive Medicine, Brown Medical School, Providence, RI.

OBJECTIVE:: Vasomotor symptoms adversely affect the quality of life and functional status of most women during the menopausal transition, but little is known about how long these symptoms last. The most effective treatment, hormone therapy (HT), carries risks and benefits that depend on the timing and duration of use. In this study we sought to estimate the duration of vasomotor symptoms in a longitudinal study. METHODS:: We reanalyzed primary data from 438 women in the longitudinal cohort of the population-based Melbourne Women's Midlife Health Project. Two hundred and five women who had completed 13 years of follow-up were included in the analyses. The onset and cessation of vasomotor symptoms were reported, stratifying analyses according to ever use of HT. Symptom duration was calculated as the time between the first and last bothersome hot flush reported. RESULTS:: The mean (SD) duration of bothersome menopausal symptoms for women who completed 13 years of follow-up and who never used HT was estimated to be 5.2 (3.8) years (median, 4 years). If women who used HT were included, the mean (SD) duration was 5.5 (4.0) years (median, 4 years). The estimated duration of symptoms varied according to the duration of longitudinal follow-up, with a mean estimate of 3.4 years (median, 3 years) when only 8 years of follow-up data were analyzed. The only factor associated with duration of hot flushes was regular exercise-more exercise was associated with shorter symptom duration. CONCLUSIONS:: The average duration of vasomotor symptoms in this sample is more than 5 years, substantially longer than had been previously reported.

Temporal associations of hot flashes and depression in the transition to menopause.

Freeman EW, Sammel MD, Lin H.

From the Departments of 1Obstetrics/Gynecology, 2Psychiatry, 3Center for Clinical Epidemiology and Biostatistics, and 4Center for Research in Reproduction and Women's Health, University of Pennsylvania School of Medicine, Philadelphia, PA.

OBJECTIVE:: The aim of this study was to evaluate associations between hot flashes and depressed mood in the menopausal transition and associations of these symptoms with reproductive hormone changes. METHODS:: A 10-year follow-up in a population-based cohort of women who had no experience of hot flashes or depressed mood at baseline was conducted. RESULTS:: The incidence of hot flashes significantly increased compared with the incidence of depressed mood in the 10-year follow-up (P < 0.001). Sixty-seven percent of the women reported hot flashes, 50% reported depressed mood, and 41% reported both symptoms during the study interval. Reporting of both hot flashes and depressed mood was greater than expected if the processes operated independently (P < 0.001). Of the women who experienced both symptoms, depressed mood was more likely to precede hot flashes (relative risk = 2.1; 95% CI, 1.5-2.9). Within-woman increases in follicle-stimulating hormone levels were associated with the onset of depressed mood in unadjusted analysis (P = 0.05). Increased follicle-stimulating hormone levels, decreased inhibin B levels, and the variability of estradiol were significantly associated with hot flashes. Follicle-stimulating hormone and inhibin B remained significantly associated with hot flashes in the final multivariable models (P < 0.001). CONCLUSIONS:: Both hot flashes and depressive symptoms occur early in the menopausal transition in women with no previous experience of these symptoms. Depressive symptoms are more likely to precede hot flashes in women who report both symptoms. The findings support the concept that the changing hormonal milieu of the menopausal transition is one of multiple factors associated with the onset of symptoms.

Alendronate/vitamin D(3) 70 mg/2800 IU with and without additional 2800 IU vitamin D(3) for osteoporosis: Results from the 24-week extension of a 15-week randomized, controlled trial.

Binkley N, Ringe JD, Reed JI, Ljunggren O, Holick MF, Minne HW, Liu M, Lamotta A, West JA, Santora AC.

University of Wisconsin-Madison, Osteoporosis Clinical Center and Research Program, 2870 University Avenue, Suite 100, Madison, WI, 53705 USA.

Although vitamin D supplementation is a fundamental part of osteoporosis treatment, many patients do not regularly take adequate amounts. A once-weekly (OW) alendronate (ALN) preparation that includes 2800 IU of vitamin D(3) in a single combination tablet (ALN+D2800) is available for treating patients and ensuring intake of vitamin D that is consistent with existing guidelines. This randomized, double-blind study extension was conducted to evaluate the safety and tolerability of ALN+D2800 and ALN+D2800 plus an additional 2800 IU vitamin D(3) single tablet supplement (ALN+D5600) administered for 24 weeks in men and postmenopausal women with osteoporosis previously treated OW for 15 weeks with either ALN or ALN+D2800. The primary endpoint was the proportion of participants who developed hypercalciuria (defined as a 24-hour urine calcium >300 mg in women or >350 mg in men and an increase of >25% versus randomization baseline) at week 39. The key secondary endpoint was the proportion of participants with vitamin D insufficiency (serum 25(OH)D <15 ng/mL [37.4 nmol/L]) at the end of the study. Hypercalciuria incidence (4.2% [ALN+D5600] vs. 2.8% [ALN+D2800]), did not differ between groups (p = 0.354). No participants developed hypercalcemia. Among the participants with vitamin D insufficiency at the week 0 baseline, the prevalence of insufficiency at the end of the study was reduced by 92% in the ALN+D5600 group and by 86% in the ALN+D2800 group. The incidences of clinical adverse experiences, including drug-related adverse experiences, were similar in both groups. In subjects previously treated with ALN+D2800 for 15 weeks, the addition of 2800 IU D(3) for 24 weeks did not produce hypercalcemia nor increase the risk of hypercalciuria.

Chronic estradiol replacement to aged female rats reduces anxiety-like and depression-like behavior and enhances cognitive performance.

Walf AA, Paris JJ, Frye CA.

Department of Psychology, United States.

Decline in the ovarian steroid, estradiol (E(2)), with the menopause transition may influence cognitive and affective processing of older women and there is evidence that hormone replacement therapies (HRTs) with E(2)-mimetics may provide benefit in some, but not all, women. The parameters that play a role in determining whether the response to HRTs is positive are of interest. It may be that the likelihood for positive responses is related to the timing of E(2)-replacement following E(2) decline. As such, in the present study an animal model was utilized to investigate this. We investigated the effects of long- versus short-term E(2)-replacement by examining cognitive (object placement task), anxiety (open field, mirror maze, light-dark transition task), and depression (forced swim task) behavior of female rats that were ovariectomized (OVX) at middle-age (14 months) or older (19 months) and implanted with E(2)-filled implants at the time of surgery or after a delay of 5 months, or OVX at 14 months of age and never replaced with E(2). Rats were tested at 20 months of age. The hypothesis that was tested was that rats would have reduced anxiety and depression behavior and improved cognitive performance with E(2)-replacement at ovarian cessation, compared to a delay in E(2)-replacement. Performance in the object placement task was improved in rats that were OVX and then received continuous E(2)-replacement, compared to those that were OVX and continuously administered placebo vehicle. In the open field and forced swim task, there was an increase in anti-anxiety and anti-depression behavior, respectively, among rats that were OVX and then received continuous E(2)-replacement, compared to OVX rats administered vehicle or those that experienced a delay in E(2)-replacement. In the mirror maze and light-dark transition task, E(2)-replacement at OVX, or after a delay, reduced anxiety-like behavior. Thus, E(2)-replacement reduced anxiety and depression behavior and improved cognitive performance of aged female rats; however, delay in E(2) treatment influenced whether there were favorable effects of E(2) in some tasks.

Longitudinal changes in sexual functioning as women transition through menopause: results from the Study of Women's Health Across the Nation.

Avis NE, Brockwell S, Randolph JF Jr, Shen S, Cain VS, Ory M, Greendale GA.

From the 1Department of Social Sciences and Health Policy, Wake Forest University School of Medicine, Winston-Salem, NC; 2Epidemiology Data Center, University of Pittsburgh, Pittsburgh, PA; 3Division of Reproductive Endocrinology, University of Michigan Health System, Ann Arbor, MI; 4Centers for Disease Control, Washington, DC; 5School of Rural Public Health, Texas A&M University System Health Sciences Center, College Station, TX; and 6Geffen School of Medicine at University of California Los Angeles, Los Angeles, CA.

OBJECTIVE:: Sexual functioning is an important component of women's lives. The extent to which the menopausal transition is associated with decreased sexual functioning remains inconclusive. This study seeks to determine if advancing through the menopausal transition is associated with changes in sexual functioning. METHODS:: This was a prospective, longitudinal cohort study of women aged 42 to 52 years at baseline recruited at seven US sites (N = 3,302) in the Study of Women's Health Across the Nation (SWAN). Cohort-eligible women had an intact uterus, had at least one ovary, were not currently using exogenous hormones, were either premenopausal or early perimenopausal, and self-identified as one of the study's designated racial/ethnic groups. Data from the baseline interview and six annual follow-up visits are reported. Outcomes are self-reported ratings of importance of sex; frequency of sexual desire, arousal, masturbation, sexual intercourse, and pain during intercourse; and degree of emotional satisfaction and physical pleasure. RESULTS:: With adjustment for baseline age, chronological aging, and relevant social, health, and psychological parameters, the odds of reporting vaginal or pelvic pain increased and desire decreased by late perimenopause. Masturbation increased at early perimenopause but declined during postmenopause. The menopausal transition was unrelated to other outcomes. Health, psychological functioning, and importance of sex were related to all sexual function outcomes. Age, race/ethnicity, marital status, change in relationship, and vaginal dryness were also associated with sexual functioning. CONCLUSIONS:: Pain during sexual intercourse increases and sexual desire decreases over the menopausal transition. Masturbation increases during the early transition, but then declines in postmenopause. With adjustment for other factors, the menopausal transition was not independently associated with reports of the importance of sex, sexual arousal, frequency of sexual intercourse, emotional satisfaction with partner, or physical pleasure.

Services of 1Rheumatology, Hospital Clínic, University of Barcelona, Institut d'Investigacions Biomédiques August Pi i Sunyer (IDIBAPS), Barcelona, Spain.

OBJECTIVE: Osteoporosis is infrequent in young premenopausal women and is often associated with secondary disorders. However, idiopathic osteoporosis may be found in this setting and few data are known on this condition. Therefore, the aim of this study was to analyse the clinical characteristics and bone remodelling abnormalities in premenopausal women with idiopathic osteoporosis.METHODS:28 premenopausal women with idiopathic osteoporosis (aged 38.3+/-7.6 years) were included. The patients had one or more fragility fractures and/or decreased bone mass (z-score <-2 in the lumbar spine or femur). In all patients, secondary causes of osteoporosis were excluded and previous skeletal fractures, family history and risk factors for osteoporosis were recorded. In addition, bone mineral density at the lumbar spine and hip, spinal x-rays, and laboratory tests including PTH, 25-hydroxyvitamin D, 1,25 (OH)<inf>2</inf> vitamin D and urinary calcium excretion were measured. Bone markers such as serum bone alkaline phosphatase (bone AP) and P1NP, and urinary hydroxyproline (HYP), NTx and CTx were measured and results were compared with those observed in a control group of 28 healthy premenopausal women. RESULTS:46% of the patients had previous fragility fractures, 53% had family history of osteoporosis, 36% had associated hypercalciuria and 30% had a BMI <20 Kg/m<sup>2</sup>. Patients with idiopathic osteoporosis had increased bone resorption markers (NTx and HYP) but normal bone formation markers when compared with healthy controls. No significant differences in the clinical and biochemical parameters were observed between patients with or without hypercalciuria. CONCLUSION:Young women with idiopathic osteoporosis have an increased bone resorption without changes in bone formation when assessed by biochemical markers.

BACKGROUND: Millions of postmenopausal women use multivitamins, often believing that supplements prevent chronic diseases such as cancer and cardiovascular disease (CVD). Therefore, we decided to examine associations between multivitamin use and risk of cancer, CVD, and mortality in postmenopausal women. METHODS: The study included 161 808 participants from the Women's Health Initiative clinical trials (N = 68 132 in 3 overlapping trials of hormone therapy, dietary modification, and calcium and vitamin D supplements) or an observational study (N = 93 676). Detailed data were collected on multivitamin use at baseline and follow-up time points. Study enrollment occurred between 1993 and 1998; the women were followed up for a median of 8.0 years in the clinical trials and 7.9 years in the observational study. Disease end points were collected through 2005. We documented cancers of the breast (invasive), colon/rectum, endometrium, kidney, bladder, stomach, ovary, and lung; CVD (myocardial infarction, stroke, and venous thromboembolism); and total mortality. RESULTS: A total of 41.5% of the participants used multivitamins. After a median of 8.0 years of follow-up in the clinical trial cohort and 7.9 years in the observational study cohort, 9619 cases of breast, colorectal, endometrial, renal, bladder, stomach, lung, or ovarian cancer; 8751 CVD events; and 9865 deaths were reported. Multivariate-adjusted analyses revealed no association of multivitamin use with risk of cancer (hazard ratio [HR], 0.98, and 95% confidence interval [CI], 0.91-1.05 for breast cancer; HR, 0.99, and 95% CI, 0.88-1.11 for colorectal cancer; HR, 1.05, and 95% CI, 0.90-1.21 for endometrial cancer; HR, 1.0, and 95% CI, 0.88-1.13 for lung cancer; and HR, 1.07, and 95% CI, 0.88-1.29 for ovarian cancer); CVD (HR, 0.96, and 95% CI, 0.89-1.03 for myocardial infarction; HR, 0.99, and 95% CI, 0.91-1.07 for stroke; and HR, 1.05, and 95% CI, 0.85-1.29 for venous thromboembolism); or mortality (HR, 1.02, and 95% CI, 0.97-1.07). CONCLUSION: After a median follow-up of 8.0 and 7.9 years in the clinical trial and observational study cohorts, respectively, the Women's Health Initiative study provided convincing evidence that multivitamin use has little or no influence on the risk of common cancers, CVD, or total mortality in postmenopausal women.

Martin CK, Church TS, Thompson AM, Earnest CP, Blair SN.

Pennington Biomedical Research Center, Louisiana State University System, 6400 Perkins Road, Baton Rouge, LA 70808, USA. Martin@pbrc.edu

BACKGROUND: Improved quality of life (QOL) is a purported benefit of exercise, but few randomized controlled trials and no dose-response trials have been conducted to examine this assertion. METHODS: The effect of 50%, 100%, and 150% of the physical activity recommendation on QOL was examined in a 6-month randomized controlled trial. Participants were 430 sedentary postmenopausal women (body mass index range, 25.0-43.0 [calculated as weight in kilograms divided by height in meters squared]) with elevated systolic blood pressure randomized to a nonexercise control group (n = 92) or 1 of 3 exercise groups: exercise energy expenditure of 4 (n = 147), 8 (n = 96), or 12 (n = 95) kilocalories per kilogram of body weight per week. Eight aspects of physical and mental QOL were measured at baseline and month 6 with the use of the Medical Outcomes Study 36-Item Short Form Health Survey. RESULTS: Change in all mental and physical aspects of QOL, except bodily pain, was dose dependent (trend analyses were significant, and exercise dose was a significant predictor of QOL change; P < .05). Higher doses of exercise were associated with larger improvements in mental and physical aspects of QOL. Controlling for weight change did not attenuate the exercise-QOL association. CONCLUSION: Exercise-induced QOL improvements were dose dependent and independent of weight change.

Is the Menopause Rating Scale accurate for diagnosing sexual dysfunction among climacteric women?

Jara D, Fuenzalida A, Figueroa R, Del Prado M, Flores D, Blümel JE, Chedraui P.

Universidad Diego Portales, Santiago, Chile.

BACKGROUND: Although several tools have been designed to assess quality of life (QoL) among middle-aged women their capacity to specifically assess sexual dysfunction (SD) remains uncertain. Moreover, if SD impairs QoL within this population, then sexual assessment becomes a key issue. OBJECTIVES: To evaluate the accuracy of the Menopause Rating Scale (MRS) in diagnosing SD among climacteric women. METHODS: In this cross-sectional study 370 women aged 40-59 years filled out the MRS and the Female Sexual Functioning Index (FSFI) simultaneously. SD among surveyed women was defined as those obtaining a total FSFI score of </=26.55. A receiver-operator curve (ROC) was used to plot and measure the diagnostic accuracy of one MRS item (item 8, assessing sexual problems) using the FSFI total score as a gold standard. RESULTS: Mean age of surveyed women was 49.3+/-5.8 years. A 56.5% of them were married, 44.3% were postmenopausal, 66.8% were sexually active and 57% had SD (FSFI total score </=26.55). ROC curve determined a score >/=1 in the MRS item 8 as a cut-off value for discriminating women with SD (78% sensitivity and 62% specificity with an area below the curve of 0.70 Swett). CONCLUSIONS: The MRS was moderately accurate for diagnosing SD among climacteric women. More research is warranted in this regard.

C-reactive Protein and Carotid Intima-media Thickness in a Population of Middle-aged Koreans.

Suh M, Lee JY, Ahn SV, Kim HC, Suh I.

Department of Preventive Medicine, Yonsei University College of Medicine, Seoul, Korea.

OBJECTIVES: This study was performed to evaluate the relationship between C-reactive protein (CRP) and carotid intima-media thickness (carotid IMT) in a population of middle-aged Koreans. METHODS: A total of 1,054 men and 1,595 women (aged 40-70 years) from Kanghwa County, Korea, were chosen for the present study between 2006 and 2007. We measured high-sensitivity CRP and other major cardiovascular risk factors including anthropometrics, blood pressure, blood chemistry, and carotid ultrasonography. Health related questionnaires were also completed by each study participant. Carotid IMT value was determined by the maximal IMT at each common carotid artery. The relationship between CRP level and carotid IMT was assessed using multiple linear and logistic regression models after adjustment for age, body mass index, menopause (women), systolic blood pressure, total/HDL cholesterol ratio, triglyceride level, fasting glucose, smoking, and alcohol consumption. RESULTS: Mean carotid IMT values from the lowest to highest quartile of CRP were 0.828, 0.873, 0.898, and 0.926 mm for women (p for trend<0.001), and 0.929, 0.938, 0.949, and 0.979 mm for men (p for trend=0.032), respectively. After adjustment for major cardiovascular risk factors, the relationship between CRP and carotid IMT was significant in women (p for trend=0.017), but not in men (p for trend=0.798). Similarly, adjusted odds ratio of increased IMT, defined as the sex-specific top quartile, for the highest versus lowest CRP quartiles was 1.55 (95% CI=1.06-2.26) in women, but only 1.05 (95% CI=0.69-1.62) in men. CONCLUSIONS: CRP and carotid IMT levels appear to be directly related in women, but not in men.

Department of Internal Medicine (S.H.C., J.H.A., S.L., H.J.C., Y.J.P., K.S.P., H.C.J., C.S.S.), Seoul National University College of Medicine.

SUMMARY Objectives: There is growing evidence about the association between bone mineral density (BMD) and vascular calcification, which is related to cardiovascular disease. Coronary multidetector row computed tomography (MDCT) is a non-invasive tool developed to precisely evaluate coronary status. We used MDCT to evaluate this association. Design and patients: Eight hundred and fifteen subjects received routine checkups. After excluding subjects with factors affecting bone metabolism and cardiovascular disease, 467 subjects were analysed. Measurements: Coronary calcification was measured with MDCT and BMD was measured with dual X-ray absorptiometry. Results: The BMD of the femur and the lumbar spine were negatively associated with the coronary calcium score (CCS) after adjusting for age in women but not in men. This inverse correlation was stronger in women with a greater time since menopause (r =-0.35 at femur, post-menopausal women vs. r=-0.10 at femur, pre-menopausal women, P < 0.05), and it was stronger at the femur than in the lumbar spine (r =-0.35 at femur vs. r =-0.16 at lumbar spine, P < 0.01). The relationship was also stronger in post-menopausal women with osteoporosis and osteopaenia than women with normal BMD. The lower BMD associated with higher coronary plaque burdens and multi-diseased coronary vessels in both men and women (P < 0.01) Conclusions: Increased CCS and subclinical atherosclerosis of plaque burdens as seen by MDCT was associated with a low BMD in all women, independent of cardiovascular risk factors and age.

Circulating levels of leptin, adiposity and breast cancer risk.

Wu MH, Chou YC, Chou WY, Hsu GC, Chu CH, Yu CP, Yu JC, Sun CA.

Graduate Institute of Life Sciences, National Defense Medical Center, Taipei, Taiwan, ROC.

The present case-control study was to investigate the relationships of plasma leptin level and anthropometric measures of adiposity with the risk of breast cancer. Questionnaire information, anthropometric measures and blood samples were taken before treatment from 297 incident cases with breast cancer and 593 controls admitted for health examination at the Tri-Service General Hospital, Taipei, between 2004 and 2006. Plasma levels of leptin were measured by RIA. Logistic regression analysis was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for assessing the associations. Overall, higher leptin concentrations were significantly associated with an increased risk of breast cancer (OR (95% CI) for top vs bottom tertile of leptin was 1.63 (1.07-2.49), P(trend)=0.009). Waist circumference was a significant anthropometric factor for breast cancer in both pre- and postmenopausal women. Furthermore, the associations of leptin with breast cancer risk remained after adjustment for obesity indices. These results suggest that leptin may have an independent role in breast tumorigenesis. Regardless of the impact of circulating leptin, more research is needed to elucidate molecular mechanisms and local leptin levels that are critical for the development of breast cancers.

BACKGROUND: Calcium and vitamin D (CaD) supplementation trials including the Women's Health Initiative (WHI) trial of CaD have shown nonsignificant reductions in total mortality. This report examines intervention effects on total and cause-specific mortality by age and adherence. METHODS: The WHI CaD trial was a randomized, double-blind, placebo-controlled trial that enrolled 36,282 postmenopausal women aged 51-82 years from 40 U.S. clinical centers. Women were assigned to 1,000 mg of elemental calcium carbonate and 400 IU of vitamin D(3) daily or placebo with average follow-up of 7.0 years. RESULTS: The hazard ratio (HR) for total mortality was 0.91 (95% confidence interval [CI], 0.83-1.01) with 744 deaths in women randomized to CaD versus 807 deaths in the placebo group. HRs were in the direction of reduced risk but nonsignificant for stroke and cancer mortality, but near unity for coronary heart disease and other causes of death. HRs for total mortality were 0.89 in the 29,942 women younger than 70 years (95% CI, 0.79-1.01) and 0.95 in the 6,340 women aged 70 and older (95% CI, 0.80-1.12; p value for age interaction = .10). No statistically significant interactions were observed for any baseline characteristics. Treatment effects did not vary significantly by season. CONCLUSIONS: In the WHI CaD trial, supplementation did not have a statistically significant effect on mortality rates but the findings support the possibility that these supplements may reduce mortality rates in postmenopausal women. These data can neither support nor refute recommendations for higher dose vitamin D supplementation to reduce cancer or total mortality.

Oestrogen - a new treatment approach for schizophrenia?

Kulkarni J.

Alfred Psychiatry Research Centre, Monash University and Alfred Hospital, Melbourne, VIC, Australia.

The oestrogen protection hypothesis proposes that oestrogen has a protective effect against onset of schizophrenia. In support of this: Epidemiological studies have shown that young women are less likely to develop schizophrenia than men of the same age, and women are more likely to develop late-onset schizophrenia after menopause. Clinical studies have shown higher psychotic symptoms in perimenopausal women, and women at the low oestrogen phase of the menstrual cycle. Animal studies provide further evidence in support of the oestrogen protection hypothesis. Three randomised double-blind placebo-controlled trials and an open-label study showed that adding oestradiol to women's usual antipsychotic medications was associated with significant abatement of schizophrenia symptoms. A small study of men with schizophrenia who received oral oestradiol valerate also showed a significant abatement in psychotic symptoms. Although oestrogen appears to be a useful treatment for schizophrenia, further research is required to determine the correct dose and duration of use of oestradiol. New types of oestrogen compounds may provide a safer, non-feminising approach for the treatment of schizophrenia.

INTRODUCTION: The prevalence of osteoporosis (OP) in Mexican population is not well known. This disease constitutes a risk factor for fractures due to OP, which result in disability, poor quality of life and increased mortality rates. OBJECTIVES: To determine prevalence of OP and osteopenia in a group of female health workers from Mexico City using central densitometry (Dual X Ray Absorptiometry-DXA); to compare the Hispanic reference database from the LUNAR DPX L unit vs. the study population; to determine the age at which the peak bone mass is reached and to explore the relationship between some well known factors for osteoporosis and bone mass. MATERIAL AND METHODS: In this prolective, cross-sectional observational study 588 healthy females older than 18 years were selected at different stages and a hip and spine densitometry (DXA) was undertaken with a LUNA DPX L unit. To determine the prevalence of osteoporosis and osteopenia we used the criteria of the Committee of Experts on Osteoporosis from the World Health Organization. RESULTS: The mean age of our study population was 42.3 years +/- 9.6 (20-65); the weight 66 kg +/- 12.1 (41-139) and height 153.9 cm +/- 5.7 (138-177). The prevalence of osteoporosis on the lumbar spine was 13.5% (IC 95%: 10.5-16) and osteopenia 27.7 (IC 95%: 24-31). On the femoral neck, the prevalence of osteoporosis was 2% (IC 95%: 1.0-3) and osteopenia 26.1% (IC 95%: 22-29). The peak bone mass on the femoral neck was found between 31 to 35 years and in the lumbar spine between 26-30 years. In these groups, the bone mineral density falls as age rises. When we compare our results to reference population from the LUNAR densitometer database and to our same study group, there is an overestimation of the prevalence of OP and osteopenia on the lumbar spine and osteopenia on the femoral neck. We found a prevalence of overweight and obesity higher to reported at the Mexican National Survey of Nutrition.

BACKGROUND: The goal of this study was to compare the characteristics of breast cancers and survival rates in HRT users versus nonusers. METHODS: Data were analyzed for 1055 patients >/=50 years of age who had definitive therapy for breast cancer from 1994 through 2002. RESULTS: There were 471 (45%) HRT users. The median age at diagnosis was 61.0 years for HRT users and 68.0 years for HRT nonusers (P < .001). HRT users more often had tumors that were <1 cm (P = .007), node negative (P = .033), and grade I (P = .016). HRT users had a decreased risk of death versus nonusers (hazard ratio = .438, 95% confidence limit = .263 to .729, P = .002). CONCLUSIONS: HRT users developed breast cancer at a younger age than nonusers; HRT use was associated with the development of biologically more favorable cancers than those that developed in nonusers; and overall and disease-free survival rates were higher in HRT users than nonusers.

OBJECTIVE: To assess the diagnostic value of transvaginal sonographic (TVS) measurement of endometrial thickness for diagnosing focal intrauterine pathology in women without abnormal uterine bleeding (AUB). METHODS: A random selection from the Danish Civil Registration System was made: 1660 women aged 20-74 years were invited to participate and 686 women were eligible and accepted inclusion (429 pre- and 257 postmenopausal). The women underwent TVS measurement of endometrial thickness and saline contrast sonohysterography (SCSH). Hysteroscopic resection with histopathology (gold standard) was performed when focal intrauterine pathology was suspected at SCSH. We excluded women with AUB (n = 237), failure of SCSH (n = 50), a scan that was not in the follicular phase (n = 11), hysteroscopy contraindicated (n = 2), and users of sequential hormone therapy (n = 9) or selective estrogen receptor modulators (n = 2). Thus, 375 women without AUB were included (217 pre- and 158 postmenopausal). Receiver-operating characteristics (ROC) curves for endometrial thickness and focal lesion were analyzed. RESULTS: Focal intrauterine pathology was confirmed in 41 women (35 with polyps, five with submucosal myomas and one with polypoidal growing cancer). For premenopausal women, the area under the ROC curve (AUC) was 0.79 (95% CI, 0.68-0.89) and for postmenopausal women it was 0.84 (95% CI, 0.76-0.92). For premenopausal women, the best negative likelihood ratio (LR- = 0.11) was obtained at an endometrial thickness of 5.2 mm, with a negative predictive value (NPV) of 99% and a positive predictive value (PPV) of 10%. For postmenopausal women the best LR- (0.08) was obtained at an endometrial thickness of 2.8 mm, with a NPV of 99% and a PPV of 26%. CONCLUSIONS: In women without AUB, TVS measurement of endometrial thickness is a poor diagnostic test, but is apparently efficacious in excluding focal intrauterine pathology, especially in postmenopausal women. The 4-5-mm threshold conventionally used to exclude endometrial malignancy in women with postmenopausal bleeding is not transferable to women without AUB for excluding focal intrauterine pathology.

BACKGROUND: Moderate intake of alcohol has been reported to have beneficial effects on bone. However, different classes of alcoholic beverages have not been investigated. OBJECTIVE: Our aim was to determine the association between intake of total alcohol or individual alcoholic beverages and bone mineral density (BMD). DESIGN: Adjusting for potential confounding factors, we examined alcohol intakes and BMD at 3 hip sites and the lumbar spine in 1182 men and in 1289 postmenopausal and 248 premenopausal women in the population-based Framingham Offspring cohort (age: 29-86 y). RESULTS: Men were predominantly beer drinkers, and women were predominantly wine drinkers. Compared with nondrinkers, hip BMD was greater (3.4-4.5%) in men consuming 1-2 drinks/d of total alcohol or beer, whereas hip and spine BMD were significantly greater (5.0-8.3%) in postmenopausal women consuming >2 drinks/d of total alcohol or wine. Intake of >2 drinks/d of liquor in men was associated with significantly lower (3.0-5.2%) hip and spine BMD than was intake of 1-2 drinks/d of liquor in men. After adjustment for silicon intake, all intergroup differences for beer were no longer significant; differences for other alcohol sources remained significant. Power was low for premenopausal women, and the associations were not significant. CONCLUSIONS: Moderate consumption of alcohol may be beneficial to bone in men and postmenopausal women. However, in men, high liquor intakes (>2 drinks/d) were associated with significantly lower BMD. The tendency toward stronger associations between BMD and beer or wine, relative to liquor, suggests that constituents other than ethanol may contribute to bone health. Silicon appears to mediate the association of beer, but not that of wine or liquor, with BMD. Other components need further investigation.

OBJECTIVE: To study the effects of combination hormone therapy (HT) on emotional processing in postmenopausal women with use of functional neuroimaging. DESIGN: A randomized, double-blind, placebo-controlled crossover study was performed. SETTING: A tertiary care university medical center. PARTICIPANT(S): Ten healthy postmenopausal women (mean age 56.9 years, SD = 1.4 years) were recruited. INTERVENTION(S): Women were assigned randomly to the order they received combined HT, 5 mug ethinyl E(2) and 1 mg norethindrone acetate, and placebo. Volunteers received HT or placebo for 4 weeks, followed by a 1-month washout period, and then received the other treatment for 4 weeks. Subjects participated in a functional magnetic resonance imaging emotional processing task, where they were asked to rate emotional pictures as positive, negative, or neutral. MAIN OUTCOME MEASURE(S): Brain activation patterns were compared between HT and placebo conditions within subjects. RESULT(S): During negative emotional presentations, after subtracting the effect of neutral images, areas of significant differences between HT and placebo conditions were identified in the orbital, frontal, cingulate, and occipital cortices. During positive emotional image presentation there were significant differences between placebo and HT conditions within the medial frontal cortex. CONCLUSIONS: Short-term menopausal treatment with combination HT affects regional brain activity within areas implicated in emotional processing.

OBJECTIVE:: Observational and experimental studies support that osteoporosis and atherosclerosis are two related phenomena. The aim of the present study was to investigate the probable effect of alendronate sodium, which is used in the treatment of osteoporosis, on carotid artery intima-media thickness (IMT), the lipid profile, and apolipoprotein A-I (ApoA-I) and apolipoprotein B (ApoB) levels, which are known to have a role in the atherosclerotic process. METHODS:: Carotid artery IMT was measured in 39 women in whom alendronate 70 mg/week was started due to osteoporosis and in 33 control participants at the start and the 6th and 12th months of the study. Triglyceride, high-density lipoprotein, low-density lipoprotein, ApoA-I, and ApoB levels were also measured at the same time points, and ApoB/ApoA-I rates were calculated. RESULTS:: Among the basal values, only the ApoA-I level was significantly lower in the alendronate group (P < 0.01). IMT measurement results (mean [SE]) of the alendronate group were 0.622 [0.015], 0.616 [0.014], and 0.597 [0.013] mm; those of the control group were 0.600 [0.010], 0.611 [0.011], and 0.620 [0.011] mm, respectively. In both groups, the difference between the start and 12-month values was significant (P < 0.05). A significant difference was not determined in the triglyceride and lipid measurement results between the groups and also within groups. ApoA and ApoB levels at the start and the 12th month of the study were as follows: 159.8 [3.6], 162.2 [3.4] (P > 0.05) and 96.2 [4.2], 101.5 [4.5] (P > 0.05) in the control group and 145.1 [4.0], 173.7 [4.3] (P < 0.05) and 98.7 [3.9], 84.6 [3.3] (P < 0.05) in the alendronate group, respectively. The ratios of ApoB/ApoA-I were 0.611 [0.029] is to 0.636 [0.031] (P > 0.05) in the control group and 0.703 [0.04] is to 0.498 [0.0] (P < 0.05) in the alendronate group. CONCLUSIONS:: We concluded that alendronate sodium resulted in a significant decrease in IMT during a 1-year period compared with matched controls. Also, alendronate was associated with a positive effect on the ApoB/ApoA-I ratio.

National Heart, Lung and Blood Institute's Framingham Heart Study, Bethesda, Md.

BACKGROUND AND PURPOSE: Women have increased lifetime stroke risk and more disabling strokes compared with men. Insights into the association between menopause and stroke could lead to new prevention strategies for women. The objective of this study was to examine the association of age at natural menopause with ischemic stroke risk in the Framingham Heart Study. METHODS: Participants included women who survived stroke-free until age 60, experienced natural menopause, did not use estrogen before menopause, and who had complete data (n=1430). Participants were followed until first ischemic stroke, death, or end of follow-up (2006). Age at natural menopause was self-reported. Cox proportional hazards models were used to examine the association between age at natural menopause (<42, 42 to 54, >/=55) and ischemic stroke risk adjusted for age, systolic blood pressure, atrial fibrillation, diabetes, current smoking, cardiovascular disease and estrogen use. RESULTS: There were 234 ischemic strokes identified. Average age at menopause was 49 years (SD=4). Women with menopause at ages 42 to 54 (hazard ratio=0.50; 95% CI: 0.29 to 0.89) and at ages >/=55 (hazard ratio=0.31; 95% CI: 0.13 to 0.76) had lower stroke risk compared with those with menopause <42 years adjusted for covariates. Women with menopause before age 42 had twice the stroke risk compared to all other women (hazard ratio=2.03; 95% CI: 1.16 to 3.56). CONCLUSIONS: In this prospective study, age at natural menopause before age 42 was associated with increased ischemic stroke risk. Future stroke studies with measures of endogenous hormones are needed to inform the underlying mechanisms so that novel prevention strategies for midlife women can be considered.

OBJECTIVE: To estimate the cost-effectiveness of five-year treatment of hormone replacement therapy (HRT) compared with no treatment for women with menopausal symptoms in the UK. METHOD: A Markov cohort simulation model with tunnel techniques was used to assess the cost-effectiveness of HRT in women aged 50 years. For the clinical effects of HRT we used, where possible, results taken from the Women's Health Initiative (WHI). The model had a life-time horizon with cycle lengths of one year and contained the following disease states: hip fracture, vertebral fracture, wrist fracture, breast cancer, colorectal cancer, coronary heart disease, stroke and venous thromboembolic events. An intervention was modelled by its impact on the disease risks during and after stopping treatment. The model was populated with UK-specific data on risks, mortality rates, quality-of-life weights and costs. The main outcome of the model was cost per quality-adjusted life year (QALY) gained of HRT compared with no treatment. RESULTS: The results indicated that it was cost-effective to treat women with menopausal symptoms with HRT in the UK. The severity of menopausal symptoms was the single most important determinant of cost-effectiveness, but HRT remained cost-effective even where symptoms were mild or effects on symptom relief were small. CONCLUSIONS: Treatment of women with menopausal symptoms with HRT is cost-effective.

OBJECTIVE: We examined the associations of total calcium intake (TCI) and dietary protein intake (DPI) with risk of fracture. METHODS: A total of 2006 postmenopausal women >/=50 y of age who were measured in the 1999-2002 National Health and Nutrition Examination Survey were included in the study. Weighted mean TCI and DPI and percentage of distributions of selected characteristics were estimated by TCI category and fracture status. Multivariate logistic regression models were used to assess the effect of TCI and DPI on risk of fracture. RESULTS: Thirteen percent of participants reported a fracture history, of whom 17.8% consumed a total of >/=1200 mg of calcium per day and 23.8% consumed <400 mg/d. TCI was not associated with fracture risk when controlling for all selected covariates. In women who consumed <46 g/d of dietary protein, those with a TCI >/=1200 mg/d had a significantly higher risk of fracture than those with the lowest TCI (adjusted odds ratio 5.98, 95% confidence interval 1.15-31.13), whereas in women who consumed >70 g/d of dietary protein, those with a TCI >/=1200 mg/d had an insignificant lower risk of fracture (adjusted odds ratio 0.69, 95% confidence interval 0.20-2.39). CONCLUSION: TCI is not associated with risk of fracture among postmenopausal women. Adequate TCI in the presence of inadequate DPI may not be protective against fractures. Optimal proportion of TCI and DPI warrants further investigation among older women.
