    It is now recognized that Cimicifuga foetida (C. foetida) extract is effective in alleviating menopausal symptoms. But the durations reported were usually short. The aim of this study was to investigate the effects of C. foetida extract therapy and different estrogen and progesterone sequential therapies, on the breasts of early postmenopausal women. This was a prospective randomized trial. Ninety-six early menopausal women were recruited and randomly assigned into three groups treated with different therapies for 2 years. Patients were given C. foetida extract in Group A, estradiol valerate and medroxyprogesterone acetate in Group B, and estradiol valerate and progesterone in Group C. Ultrasonography was used to monitor changes in breast during treatment. In comparing breast glandular section thickness before and after 1 and 2 years of treatment, no significant difference was observed in Group A (11.97 ± 2.84 mm vs. 12.09 ± 2.58 mm and 12.61 ± 3.73 mm, P > 0.05); in Group B glandular section thickness had increased significantly (10.98 ± 2.34 mm vs. 11.84 ± 2.72 mm and 11.90 ± 3.33 mm, P 0.05); in Group B the duct width had a downward trend after treatment (0.99 ± 0.14 mm vs. 0.96 ± 0.22 mm and 0.90 ± 0.18 mm, P < 0.05), the same as Group C (1.07 ± 0.20 mm vs. 1.02 ± 0.17 mm and 0.91 ± 0.19 mm, P < 0.05). The nodules detected before treatment had disappeared after 1-year of treatment or exhibited no distinct changes in the three groups. However, new breast nodules had appeared after 2 years of treatment: There was one case in Group A, two cases in Group B and four cases in Group C, with breast hyperplasia after the molybdenum target check. In early postmenopausal patients, C. foetida extract therapy and estrogen and progesterone therapy at low doses did not increase the incidence of malignant breast tumors.

    The aim of this study was to evaluate the differences in sleep between women of early and late post-menopause. Thirty post-menopausal women who came to the climacteric service of their own volition were selected. Fourteen were in early post-menopause (less than 5 years after menopause), and sixteen were in late post-menopause (more than 5 years since menopause). None of the women were suffering from any other clinical diseases. Participants had no previous history of hormone therapy or hypnotic drug use. These patients were not previously selected with regard to any sleep complaints. All participants answered a sleep questionnaire and underwent a polysomnography recording. Subjective complaints included body pain, bruxism, anxiety, depression, lack of concentration, and sleepiness (measured by the Epworth Sleepiness Scale). These complaints were more frequent in the late post-menopause group. In contrast, complaints of memory impairment were more frequent in the early post-menopause group (psleep were higher in the late post-menopausal group.

    Postmenopausal osteoporosis is one of the most prominent worldwide public health problems and the morbidity is increasing with the aging population. It has been demonstrated that early diagnosis and intervention delay the disease progression and improve the outcome. Therefore, searching for biomarkers that are able to identify postmenopausal women at high risk for developing osteoporosis is an effective way to improve the quality of life of patients, and alleviate social and economic burdens. In the present study, a protein array was used to identify potential biomarkers. The bone mineral densities of 10 rats were dynamically measured in an ovariectomized model by micro‑computed tomography assessment, and the early stage of osteoporosis was defined. Through the protein array‑based screening, the expression levels of six serum protein biomarkers in ovariectomized rats were observed to alter at the initiation stage of the postmenopausal osteoporosis. Fractalkine, tissue inhibitor of metalloproteinases‑1 and monocyte chemotactic protein‑1 were finally demonstrated to be increased in the serum of eight enrolled postmenopausal osteoporosis patients using ELISA assay and were correlated with the severity of progressive bone loss. These biomarkers may be explored as potential early biomarkers to readily evaluate and diagnose postmenopausal osteoporosis in the clinic.

    To investigate the relationship between endogenous androgens and body fat distribution in early and late postmenopausal women. We enrolled postmenopausal women consisting of an early group (≤ 5 years since menopause, n = 105) and a late group (≥ 10 years since menopause, n = 107). Each group was subdivided into normal weight (BMI testosterone (T), dehydroepiandrosterone-sulfate (DHEA-S) and sex hormone-binding globulin (SHBG) levels were measured. Body fat distribution was evaluated by dual-energy X-ray absorptiometry (DEXA). Late postmenopausal women had a higher proportion of body fat than early postmenopausal women. The body fat of the overweight and obese women had a greater tendency to accumulate in the abdomen compared with the normal weight women both in early and late postmenopausal groups. The overweight and obese women had a higher free testosterone (FT) than the normal weight women in early postmenopausal women (Pfat distribution both in early and late postmenopausal groups (P>0.05).The FT in early postmenopausal women and the DHEA-S levels in late postmenopausal women correlated positively with the trunk/leg fat ratio (T/L) and the proportion of android fat whereas correlated negatively with the proportion of gynoid fat in the partial correlation and multiple linear regression analyses (all Pfat distribution, the FT in early postmenopausal women and DHEA-S levels in late postmenopausal women correlate positively with abdominal fat accumulation.

    Objective: This double-blind, placebo-corrected clinical pilot study was aimed at assessing the use of hypocotyls of cruciferous Andean plant Maca (Lepidium peruvianum Chacon), in alleviating symptoms of menopausal discomfort experienced by women in early post menopause as measured by profiles of serum hormones: Luteinizing Hormone (LH), Follicle-stimulating Hormone (FSH), Estrogen (E2) and Progesterone (PG) and as assessed by Greene’s Menopausal Index. Design: Study was conducted on 20 Caucasian healthy early-postmenopausal women volunteers during the three months period (Trial I) and on eight women during nine months period (Trial II). Hormone levels were determined in blood with a simultaneous assessment of menopausal index at the start of study, after one month use of placebo, and after two and eight months administration of 2g gelatinized Maca root powder (Maca-GO) in the form of two 500mg hard gel capsules, twice daily. Results: In comparison to placebo, after both, two and eight months administration of Maca-GO capsules to EPMW, level of FSH significantly (PMaca-GO treatment only. There was a significant (PMaca-GO when used in EPMW, depending on the length of use, was acting as a toner of hormonal processes as reflected by decrease in FSH and increased LH secretion, which stimulated production of both ovarian hormones, E2 and PG and resulted in a substantial reduction of menopausal discomfort felt by women participating in the study, with a distinctive placebo effect, thus, fully justifying further, more complex study on effectiveness of Maca-GO as a reliable alternative to HRT program.

    Osteoporosis is difficult to treat and is still incurable, and thus prevention is critically important. The aim of this study was to find out the high-risk women for osteoporosis and to correlate their bone mineral density (BMD) with their investigated risk factors. Cross-sectional design was used and it was conducted among 200 pre- and postmenopausal Saudi women. The study documented that postmenopausal females had high prevalence of osteopenia and majority of them had low serum calcium. Significant correlation was found between low BMD and family history of osteoporosis; increased BMD was seen in women, who consumed calcium-rich foods, exposure to sun light, and longer fertility period. Majority of the women 94.5% had inadequate knowledge on preventive measures of osteoporosis. The high prevalence of osteopenia in postmenopausal women indicates the ultimate importance of early intervention to prevent development of osteoporosis in later life.

    Cardiovascular disease (CVD) is the leading cause of death among postmenopausal women. Changes in endothelial function play an important role in the pathophysiology of atherosclerosis, and evidence suggests that interventions to improve endothelial function could modify the rates of progression and the risk of cardiovascular events. In addition, a positive association between markers of endothelial dysfunction and androgenicity has been described in women with polycystic ovary syndrome, suggesting a correlation with the early-onset endothelial dysfunction found in these patients. We performed a cross-sectional study to verify whether endogenous testosterone levels are correlated with markers of inflammation and endothelial function and with anthropometric and metabolic profile in 53 postmenopausal women. Serum testosterone, sex hormone-binding globulin, C-reactive protein (CRP), fibrinogen, and plasma endothelin-1 (ET-1) were determined. Patients were stratified into 2 groups (higher or lower than the mean testosterone levels of the studied sample). Mean age was 55 years (+/-5), and median time since menopause was 5.5 years (interquartile range, 3-8 years). Body mass index and waist circumference were significantly higher in the group with testosterone levels >or=0.49 ng/mL. Median CRP levels were greater in the group with higher testosterone levels (1.17 [0.17-2.36] vs 0.17 [0.17-0.61] mg/L, P = .039). Median ET-1 levels were also higher in women with greater testosterone levels (0.84 [0.81-0.97] vs 0.81 [0.74-0.84] pg/mL, P = .023). An association of testosterone with CRP (r = 0.416, P = .004) and ET-1 (r = 0.323, P = .031) was observed. This association was dependent on homeostasis model assessment index for ET-1 but not CRP. Testosterone was also associated with waist circumference and blood pressure (P = .001). These data suggest that endogenous testosterone levels in recently postmenopausal women may be part of a proatherogenic profile. Longitudinal studies

    Idiopathic osteoporosis mainly affects postmenopausal women. The normal trabecular volume of the lumbar vertebrae in a sample of healthy perimenopausal women was established by monoenergetic computed tomography. Early diagnosis of diminished bone mass is crucial for the identification of women at risk for involutionary osteoporosis following climacteric estrogen depletion. Body weight, endogenous levels of sex steroids, renal calcium and hydroxyproline excretions are not related to individual bone mass in the lumbar spine.

    To evaluate the effectiveness of a topical vaginal preparation containing hyaluronic acid in controlling signs and symptoms correlated with postmenopausal vulvovaginal atrophy (VVA). A prospective, observational study has been performed at the Obstetrics and Gynecology Department of the Vita Salute San Raffaele University of Milan, Italy. Forty-six (46) consecutive postmenopausal women complaining of genital discomfort due to postmenopausal estrogen lack have been enrolled. All patients have been investigated by the use of the Vaginal Health Index (VHI) and of a Visual Analogic Scale (VAS) of symptoms at baseline and one month after the end of the study. The treatment protocol consisted of the administration of a hyaluronic acid-based liquid preparation for vaginal use (Justgin®, Just Pharma, Rome, Italy) three times a week, for a total of 8 weeks. Statistical analysis of VHI and VAS scores has been performed by the use of the Wilcoxon signed-rank test for repeated values, assuming a p-value Hyaluronic acid topical approach with a liquid preparation for vaginal use (Justgin®, Just Pharma, Roma, Italy) to control signs and symptoms of vulvovaginal atrophy (VVA) in postmenopausal women demonstrated significant effectiveness both in terms of objective and subjective improvement.

    To assess the association of different components of physical fitness with HRQoL in early postmenopause and to test which physical fitness components are independently associated with the physical and mental components of HRQoL. The final sample comprised 67 early postmenopausal women. Physical fitness was assessed with the Senior Fitness Test battery (additionally including handgrip strength test), and HRQoL was evaluated with the Short-Form Health Survey-36 (SF-36). We also analyzed plasma gonadotropic hormones and estradiol. Overall, most of the fitness components were positively associated with HRQoL. Lower-body flexibility, upper-body muscle strength and cardiorespiratory fitness were the fitness components more strongly associated with HRQoL (r range from 0.28 to 0.56). Static balance was especially associated with mental health (r = -0.46, P fitness (assessed with the 6-min walk test, P fitness is associated with better HRQoL in early postmenopause. Lower-body flexibility and upper-body muscle strength were the most important independent fitness indicators, explaining ~30 % of HRQoL.

  3. [China expert consensus on the management of dyslipidemia in postmenopausal patients with early-stage breast cancer].

    Science.gov (United States)

    2017-01-23

    Estrogen has an impact on the type of lipoproteins and the blood lipid levels, thus protecting the cardiovascular system. Postmenopausal breast cancer patients suffer a significant decrease in estrogen levels due to both physiological changes and the use of drugs, and thus have a higher risk of atherosclerotic cardiovascular diseases. Therefore, strict lipid management is required for postmenopausal breast cancer patients receiving endocrine therapy. However, no guidelines have been developed in terms of lipid management and intervention for postmenopausal breast cancer patients. The Chinese expert group of multidisciplinary management of dyslipidemia in breast cancer patients with endocrine therapy, after deep investigation into the management of dyslipidemia in postmenopausal patients with early-stage breast cancer, has developed the China Expert Consensus on Dyslipidemia Management in Postmenopausal Patients with Early-stage Breast Cancer. The Consensus clearly defines the goals and measures of interventions for dyslipidemia, hoping to effectively reduce the risk of atherosclerotic cardiovascular disease in postmenopausal breast cancer patients and further improve the long-term survival of the patients.

    Variations in the hormonal milieu after menopause may influence neural processes concerned with cognition, cognitive aging, and mood, but findings are inconsistent. In particular, cognitive effects of estradiol may vary with time since menopause, but this prediction has not been assessed directly using serum hormone concentrations. We studied 643 healthy postmenopausal women not using hormone therapy who were recruited into early (y after menopause) and late (10+ y after menopause) groups. Women were administered a comprehensive neuropsychological battery and assessed with the Center for Epidemiologic Studies Depression Scale. They provided serum for free estradiol, estrone, progesterone, free testosterone, and sex hormone binding globulin measurements. Cognitive outcomes were standardized composite measures of verbal episodic memory, executive functions, and global cognition. Covariate-adjusted linear regression analyses were conducted for each hormone separately and after adjustment for other hormone levels. Endogenous sex steroid levels were unassociated with cognitive composites, but sex hormone binding globulin was positively associated with verbal memory. Results for early and late groups did not differ significantly, although progesterone concentrations were significantly positively associated with verbal memory and global cognition in early group women. Hormone concentrations were not significantly related to mood. Results fail to support the hypothesis that temporal proximity to menopause modifies the relation between endogenous serum levels of estradiol and verbal memory, executive functions, or global cognition. Physiological variations in endogenous postmenopausal levels of sex steroid hormones are not substantially related to these aspects of cognition or mood; positive associations for progesterone and sex hormone binding globulin merit additional study.

    To determine the association of serum paraoxonase concentration with serum lipid levels and bone mineral density in early postmenopausal Turkish women. One hundred healthy postmenopausal women were included in a cross-sectional study in a University hospital clinic. Blood was drawn from women who had bone mineral density (BMD) measurements during routine visits. BMD of the lumbar vertebrae was measured by dual-energy X-ray absorptiometry. The serum paraoxonase concentration and serum lipid levels were measured. Women were divided into two groups: those with normal lumbar vertebrae BMD and those with osteopenic lumbar vertebrae. Serum paraoxonase concentration was compared between the groups. The correlation between serum paraoxonase concentration and bone mass parameters was performed using Pearson's test. The paraoxonase concentration in the osteopenic group was significantly lower than in the group with normal lumbar vertebrae BMD. The paraoxonase concentration was moderately correlated with total cholesterol, low density lipoprotein cholesterol and triglyceride levels among early postmenopausal Turkish women. Early postmenopausal women with osteopenic lumbar vertebrae have significantly lower paraoxonase concentration than those with normal lumbar vertebrae BMD. Further studies are needed to clarify the associations between the osteoporosis risk factors and paraoxonase concentration during late postmenopausal years.

Nuti.; 2Department of Human Pathology and Oncology, Medical Oncology Section, University of Siena, Italy (Dir. G. FranciniAbstract: The third-generation aromatase inhibitors (AIs, letrozole, anastrozole and exemestane, are becoming the first choice endocrine drugs for post-menopausal women with breast cancer, since they present greater efficacy when compared with tamoxifen in both adjuvant and metastatic setting. In particular, several large and well designed trials have suggested an important role for AIs in the adjuvant treatment of postmenopausal women with estrogen-receptor positive breast cancer either in the upfront, sequential or extended adjuvant mode. Overall, AIs are associated with a small but significant improvement in disease free survival. The expanding use of AIs in the treatment of early breast cancer means that individual patients will be exposed to the agents for longer durations, making it increasingly important to establish their long-term safety. This review focused on the effects of AIs on bone metabolism, serum lipids and cardiovascular risk. AIs have adverse effects on bone turnover with a reduction of bone mineral density and an increase in the rate of fragility fractures. With respect to tamoxifen AIs present lower thrombotic risk and a less favorable impact on lipid profile, whereas the true effects on cardiovascular risk still remain to be clarified. An adequate monitoring of bone mineral density (BMD and lipid profile could be recommended for post-menopausal women candidate to AIs.Keywords: breast cancer, aromatase inhibitors, bone loss, lipids, cardiovascular risk

    Full Text Available BACKGROUND: Postmenopausal women experience undesired symptoms that adversely affect their quality of life. In the recent years, a specific 12 - week fractional CO2 laser treatment has been introduced, with highly significant relief of symptoms. AIM: The aim of this paper is the identification of the early modifications of structural components of atrophic vaginal mucosa induced by laser irradiation, which is responsible for the restorative processes. MATERIAL AND METHODS: We investigated by microscopical, ultrastructural and biochemical methods the modifications of the structural components of postmenopausal atrophic vaginal mucosa tissues after 1 hour following a single fractional laser CO2 application. RESULTS: In one hour, the mucosal epithelium thickens, with the maturation of epithelial cells and desquamation at the epithelial surface. In the connective tissue, new papillae indenting the epithelium with newly formed vessels penetrating them, new thin fibrils of collagen III are also formed in a renewed turnover of components due to the increase of metalloproteinase - 2. Specific features of fibroblasts support stimulation of their activity responsible of the renewal of the extracellular matrix, with an increase of mechanical support as connective tissue and stimulation of growth and maturation to epithelium thanks to new vessels and related factors delivered. CONCLUSION: We found the activation of regenerative mechanisms expressed both in the connective tissue - with the formation of new vessels, new papillae, and new collagen - and in the epithelium with the associated thickening and desquamation of cells at the mucosal surface.

    Our purpose was to study combinations of estradiol and gestodene for prevention of bone loss in early postmenopausal women. We randomly assigned 278 healthy, early postmenopausal women to receive either 2 mg 17beta-estradiol sequentially combined with 25 microg gestodene (group 2/25s), 2 mg estradiol sequentially combined with 50 microg gestodene (group 2/50s), 1 mg estradiol sequentially combined with 25 microg gestodene (group 1/25s), 1 mg estradiol continuously combined with 25 mg gestodene (group 1/25c), or placebo. After 3 years the changes in bone mineral density of the spine were as follows (mean +/- SEM): group 2/25s, 7. 41% +/- 0.72%; group 2/50s, 8.53% +/- 0.90%; group 1.25s, 6.67% +/- 0.88%; group 1/25c, 4.44% +/- 0.59%; and placebo group, -2.03% +/- 0. 64%. The changes in bone mineral density were mirrored in the biochemical bone markers. The average responses for the urinary C-terminal telopeptide fragments of type I collagen corrected for creatinine excretion were as follows (mean of baseline +/- SEM): group 2/25s, -68.8% +/- 0.03%; group 2/50s, -72.8% +/- 0.02%; group 1/25s, -60.7% +/- 0.03%; group 1/25c, -52.28% +/- 0.04%; and placebo group, 6.5% +/- 0.09%. Beneficial lipid effects were found in all active groups. The decreases in low-density lipoprotein were as follows (mean +/- SEM): group 2/25s, -13.7% +/- 3.0%; group 2/50s, -14.6% +/- 3.2%; group 1/25s, -9.28% +/- 2.2%; group 1/25c, -9.92% +/- 2.4%; and placebo group, 1.53% +/- 1.9%. These results demonstrate that estradiol therapy with 1 mg estradiol is fully protective against early postmenopausal bone loss.

    The aim of this study was to evaluate the relationship between vitamin E status and osteoporosis in early postmenopausal women. Anthropometric data, osteoporosis risk factors, vitamin E serum levels, bone mineral density (BMD) and other serum parameters which may influence bone mineral density in postmenopausal women were analyzed in a cross-sectional study. The association between osteoporosis and age, age of menopause, body mass index, osteocalcin, calcium, vitamin D, vitamin E (measured as 25 hydroxyvitamin D and as α-tocopherol:lipids ratio, respectively), bone alkaline phosphatase, smoking status, leisure physical activity and alcohol intake were modeled by a multivariate logistic regression and multi-linear regression analysis in 232 early postmenopausal women. A lower vitamin E:lipid ratio was associated with osteoporosis in multivariate logistic regression. In a multivariate linear model with BMD of the lumbar spine as a dependent variable, the vitamin E:lipid ratio was clearly related with BMD of the lumbar spine (F ratio = 6.30, p = 0.002). BMD of the lumbar spine was significantly higher in the highest tertile of the vitamin E:lipid ratio than in the lowest tertile. The mean vitamin E:lipid ratio was significantly lower in osteoporotic postmenopausal women (T score ≤-2.5) (3.0 ± 0.6 μmol/mmol) than normal (neither osteoporotic nor osteopenic) postmenopausal women (T score >-1) (3.5 ± 0.7 μmol/mmol) using multivariable-adjusted BMD. These findings highlight that vitamin E may increase BMD in healthy postmenopausal women.

    Women who pass menopause face many changes that may lead to loss of health-related fitness (HRF), especially if sedentary. Many exercise recommendations are also relevant for early postmenopausal women; however, these may not meet their specific needs because the recommendations are based mainly on studies on men. We conducted a systematic review for randomised, controlled exercise trials on postmenopausal women (aged 50 to 65 years) on components of HRF. HRF consists of morphological fitness (body composition and bone strength), musculoskeletal fitness (muscle strength and endurance, flexibility), motor fitness (postural control), cardiorespiratory fitness (maximal aerobic power, blood pressure) and metabolic fitness (lipid and carbohydrate metabolism). The outcome variables chosen were: bodyweight; proportion of body fat of total bodyweight (F%); bone mineral density (BMD); bone mineral content (BMC); various tests on muscle performance, flexibility, balance and coordination; maximal oxygen consumption (V-dotO(2max)); resting blood pressure (BP); total cholesterol (TC); high-density lipoprotein-cholesterol; low-density lipoprotein-cholesterol; triglycerides; blood glucose and insulin. The feasibility of the exercise programme was assessed from drop-out, attendance and injury rates. Twenty-eight randomised controlled trials with 2646 participants were assessed. In total, 18 studies reported on the effects of exercise on bodyweight and F%, 16 on BMD or BMC, 11 on muscular strength or endurance, five on flexibility, six on balance or coordination, 18 on V-dotO(2max), seven on BP, nine on lipids and two studies on glucose an one on insulin. Based on these studies, early postmenopausal women could benefit from 30 minutes of daily moderate walking in one to three bouts combined with a resistance training programme twice a week. For a sedentary person, walking is feasible and can be incorporated into everyday life. A feasible way to start resistance training is to

    Regional values of bone mineral content and bone mineral density were calculated from total body dual photon absorptiometry scans of 52 early postmenopausal women treated with estrogen for one year and of 52 similar women treated with placebo. The six regions were head, arms, chest, spine, pelvis, and legs. In addition, bone mineral density of the spine was calculated by dual photon absorptiometry and bone mineral content of the forearm by single photon absorptiometry, using separate special purpose scanners. All regions were unchanged after one year of treatment with estrogen, excluding the lumbar spine, for which values rose. Values for all regions except the lumbar spine fell significantly in the placebo group. The rates of loss ranged from 2 to 8%, with no significant differences between the regions. It is concluded that loss of bone in the early menopause is a generalized phenomenon, affecting all parts of the skeleton. Furthermore, estrogen prophylaxis for loss of bone is effective in all parts of the skeleton. Finally, it is suggested that the measurement of bone mineral content in the forearm be used for clinical follow up of bone changes, as this method is superior to others in the ratio of change to precision

    Full Text Available Background/Aim. The most common secondary manifestations of menopause are clinical manifestations of estrogen deficiency. They could be early and late. The aim of this study was to compare manifestations of somatic disturbances in early postmenopause in women after physiological and surgical menopause. Methods. This prospective study included 60 women, age 41-55 years, divided into two groups: physiological (30 of them and surgically induced menopause. For every subject a special evidence list, consisting of the disease history questions, physical and gynecology examination as well as dates about physiological variables (arterial tension, height, weight, and body-mass index and laboratory examination was formed. The values of arterial blood pressure, body height, body mass, body mass index (BMI, and lipid status were determined and gynecological examinations were performed in each patient. Results. The most frequent symptoms in both groups were vasomotor ones. Headache was the more intensive sign in the group after induced menopause. Extra systolic heart excursion was a common symptom in both study groups. Arterial tension, regardless of the type of menopause, was in the physiological range. The frequent organic signs of menopause, more intensive in the group after induced menopause, were genitourinary and skin atrophy. An analysis of the BMI showed that the women in both groups were obese (BMI > 25. The lipids analysis confirmed the predomination of hyperlipoproteinemia type IIa in the group with physiologic menopause and type IIb after induced menopause. Conclusion. The dominant signs of menopausal syndrome were vasomotor and bone-joint symptoms, more frequent in the group after induced menopause. There were no statistically significant differences between the study groups according to the genitourinary atrophy and other signs of aging. Menopausal hormonal changes, regardless of the way of menopause developing, increase the risk for

    2016-09-01

    Full Text Available Cognitive changes after menopause are a common complaint, especially as the loss of estradiol at menopause has been hypothesized to contribute to the higher rates of dementia in women. To explore the neural processes related to subjective cognitive complaints, this study examined resting state functional connectivity in 31 postmenopausal women (aged 50-60 in relationship to cognitive complaints following menopause. A cognitive complaint index was calculated using responses to a 120-item questionnaire. Seed regions were identified for resting state brain networks important for higher-order cognitive processes and for areas that have shown differences in volume and functional activity associated with cognitive complaints in prior studies. Results indicated a positive correlation between the executive control network and cognitive complaint score, weaker negative functional connectivity within the frontal cortex, and stronger positive connectivity within the right middle temporal gyrus in postmenopausal women who report more cognitive complaints. While longitudinal studies are needed to confirm this hypothesis, these data are consistent with previous findings suggesting that high levels of cognitive complaints may reflect changes in brain connectivity and may be a potential marker for the risk of late-life cognitive dysfunction in postmenopausal women with otherwise normal cognitive performance.

    Aromatase inhibitor (AI) use results in low estrogen levels, which in turn affect bone mineral density (BMD). Periodontitis, alveolar bone loss, and tooth loss are associated with low BMD. The goal of this study is to assess the prevalence of periodontitis and perceived oral health and evaluate salivary biomarkers in postmenopausal women who are survivors of early-stage (I to IIIA) breast cancer (BCa) and receive adjuvant AI therapy. Participants included 58 postmenopausal women: 29 with BCa on AIs and 29 controls without BCa diagnoses. Baseline periodontal status was assessed with: 1) periodontal probing depth (PD); 2) bleeding on probing (BOP); and 3) attachment loss (AL). Demographic and dental utilization information was gathered by questionnaire. Linear regression modeling was used to analyze the outcomes. No differences were found in mean PD or number of teeth. The AI group had significantly more sites with BOP (27.8 versus 16.7; P = 0.02), higher worst-site AL (5.2 versus 4.0 mm; P tobacco use, dental insurance, and previous radiation and chemotherapy exposure demonstrated that AI use increased AL by >2 mm (95% confidence interval, 0.46 to 3.92). Median salivary osteocalcin and tumor necrosis factor-α levels were significantly higher in the AI group than the control group. This first investigation of the periodontal status of women initiating adjuvant AI therapy identifies this population as having an increased risk for periodontitis.

    Roux-en-Y gastric bypass (RYGB) surgery is a highly effective treatment for obesity but negatively affects the skeleton. Studies of skeletal effects have generally examined areal bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA), but DXA may be inaccurate in the setting of marked weight loss. Further, as a result of modestly sized samples of mostly premenopausal women and very few men, effects of RYGB by sex and menopausal status are unknown. We prospectively studied the effects of RYGB on skeletal health, including axial and appendicular volumetric BMD and appendicular bone microarchitecture and estimated strength. Obese adults (N = 48; 27 premenopausal and 11 postmenopausal women, 10 men) with mean ± SD body mass index (BMI) 44 ± 7 kg/m 2 were assessed before and 6 and 12 months after RYGB. Participants underwent spine and hip DXA, spine QCT, radius and tibia HR-pQCT, and laboratory evaluation. Mean 12-month weight loss was 37 kg (30% of preoperative weight). Overall median 12-month increase in serum collagen type I C-telopeptide (CTx) was 278% (p effects of RYGB on axial and appendicular bone mass and microarchitecture are detectable as early as 6 months postoperatively. Postmenopausal women are at highest risk for skeletal consequences and may warrant targeted screening or interventions. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

    Full Text Available Introduction. Endocrine therapy (ET is an integral part of breast cancer (BC treatment with surgical resection remaining the cornerstone of curative treatment. The objective of this study is to compare the survival of elderly postmenopausal women with hormone receptor-positive early-stage BC treated with ET alone, without radiation or chemotherapy, versus ET plus surgery. Materials and Methods. This is a retrospective study based on a prospective database. The medical records of postmenopausal BC patients referred to the surgical oncology service of two hospitals during an 8-year period were reviewed. All patients were to receive ET for a minimum of four months before undergoing any surgery. Results. Fifty-one patients were included and divided in two groups, ET alone and ET plus surgery. At last follow-up in exclusive ET patients (n=28, 39% had stable disease or complete response, 22% had progressive disease, of which 18% died of breast cancer, and 39% died of other causes. In surgical patients (n=23, 78% were disease-free, 9% died of recurrent breast cancer, and 13% died of other causes. Conclusions. These results suggest that surgical resection is beneficial in this group and should be considered, even for patients previously deemed ineligible for surgery.

    The relationship between menopausal hormone therapy (MHT) and cardiovascular risk remains controversial, with a number of studies advocating the use of MHT in reducing risk of cardiovascular diseases, while others have shown it to increase risk. The aim of this study was to determine the association between menopausal hormone therapy and high blood pressure. A total of 43,405 postmenopausal women were included in the study. Baseline data for these women were sourced from the 45 and Up Study, Australia, a large scale study of healthy ageing. These women reported being postmenopausal, having an intact uterus, and had not been diagnosed with high blood pressure prior to menopause. Odds ratios for the association between MHT use and having high blood pressure were estimated using logistic regression, stratified by age (high blood pressure: past menopausal hormone therapy use: high blood pressure, with the effect of hormone therapy use diminishing with increasing age. Menopausal hormone therapy use is associated with significantly higher odds of having high blood pressure, and the odds increase with increased duration of use. High blood pressure should be conveyed as a health risk for people considering MHT use.

    India seems to have the highest prevalence of osteoporosis. With growing awareness of osteoporosis and its impact on life span especially in India, special attention is being paid to early detection, management and treatment of postmenopausal osteoporosis in women. Measurement of BMD and osteocalcin are of value in estimating bone turnover rates. The aim of this study is (1) to measure the specific, sensitive bone formation marker such as osteocalcin and BMD in postmenopausal osteoporosis women and postmenopausal non-osteoporosis women; (2) the follow up study to evaluate the impact of specific antiresorptive therapy (alendronate + calcium + vitamin D) regimen in postmenopausal osteoporosis by assaying osteocalcin and BMD. Sixty clinically diagnosed postmenopausal osteoporosis patients and 60 normal subjects (postmenopausal non-osteoporosis women) were recruited as control. Mean bone mineral density T score and Z score was significantly decreased (P osteoporosis patients as compared to controls. Highly significant increase in the mean score of BMD-T score and Z score from baseline to post therapy of 3 months was observed in postmenopausal osteoporosis women. Serum osteocalcin levels were significantly increased (P osteoporosis women. BMD is the best quantifiable predictor of osteoporotic fracture and osteocalcin is specific, sensitive, promising, currently used marker for better prognosis of osteoporosis and for monitoring responses to antiresorptive therapy.

    We previously reported that alendronate and risedronate reduce the urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX) by 44.9% and 34.7%, respectively, at 3 months after the start of treatment, and increase the speed of sound (SOS) of the calcaneus by 0.6% and 0.65%, respectively, at 12 months after the start of treatment in postmenopausal women with osteoporosis. The aim of the present clinical practice-based observational study was to examine the effect of treatment with minodronate for 12 months on the SOS of the calcaneus and on bone turnover markers in postmenopausal women with an increased risk of fractures. Forty-two postmenopausal women with osteoporosis or osteopenia with a clinical risk factor for fractures who had been treated with minodronate for > 12 months were enrolled in the study. The SOS and bone turnover markers were monitored during treatment with minodronate for 12 months. Compared to their baseline values, the urinary levels of NTX at 3 months and the serum levels of alkaline phosphatase at 12 months were significantly decreased at 47.5% and 25.8%, respectively. At 12 months, the SOS increased modestly, but significantly, by 0.47%, compared to the baseline value. The present study confirmed that minodronate suppressed bone turnover and modestly increased the SOS of the calcaneus in postmenopausal women with an increased risk of fractures. Copyright © 2015.

    Objective To evaluate the association of depression, sleep disturbance and menopausal symptoms with diminished libido. Study Design Data from a 2001-2002 baseline survey of 341 peri- and postmenopausal women, ages 45-55, participating in a randomized trial was analyzed. Eligibility included at least two hot flashes and/or night sweats per day and no hormone therapy for at least the prior 3 months. The survey evaluated sexual function, depression, sleep and vasomotor symptoms. We examined the association between these factors, using multivariate regression models. Results Of 341 women, 64% had diminished libido, 18% had moderate-severe depression, and 43% had poor sleep quality. Women averaged 4.6 hot flashes and 1.9 night sweats per day. Depressive symptoms (P=0.003), poor sleep (P=0.02), and night sweats (P=0.04), were significantly associated with diminished libido. Conclusions Factors associated with diminished libido in midlife are complex but include depression, disturbed sleep and night sweats, all common symptoms of the menopausal transition and early menopause.

    The aim of this study is to provide a thorough updated review of the diagnosis and treatment of postmenopausal osteoporosis. There have been several important findings in the field of postmenopausal osteoporosis over the past 1-2 years. Fewer morphometric vertebral fractures were found in women treated for 6 years with zoledronic acid compared with those who stopped treatment after 3 years. Longer duration of bisphosphonate therapy is associated with a higher risk of atypical femur fractures. Combination therapy with teriparatide and denosumab appears to increase bone mineral density to a greater extent than either therapy alone in postmenopausal women at high risk for fracture. There are several novel therapies under investigation for the treatment of osteoporosis, which are in various stages of development. Nonadherence to osteoporosis therapies continues to be a major problem in clinical practice. There are numerous effective pharmacologic treatment options for postmenopausal osteoporosis. Bisphosphonate drug holidays continue to be an area of significant debate.

    With quantification techniques of the spinal bone condition, especially with spinal biphotonic absorptiometry, early screening of patients risking subsequent development of osteoporosis complicated with vertebral compression is possible. An investigation was conducted in Lower Normandy, in 386 women who had undergone menopause or an ovariectomy, with ages ranging between 40 and 56 years; 274 were in a peri-menopausal state. A curve of the bone mineral content according to age was previously established. From this curve, in semilogarithmic representation, each patient risk was assessed. This risk is considered as high in 30 p. cent of the patients, non existent in 52 p. cent and 18 p. cent are borderline. The percentage of high risk patients increases with the number of years since menopause. It is hoped that the incidence of osteoporosis will decrease with early screening and preventive therapeutic measures [fr

    The Medication Use Patterns, Treatment Satisfaction, and Inadequate Control of Osteoporosis Study (MUSIC OS-EU) was designed to better understand the rate and burden of gastrointestinal (GI) events on clinical and health care outcomes among postmenopausal women with osteoporosis. MUSIC OS-EU is a prospective, multinational, observational cohort study of postmenopausal women ≥50 years of age diagnosed with osteoporosis and enrolled in physician clinics in six countries: France, Italy, the Netherlands, Sweden, the United Kingdom, and Canada. The MUSIC OS-EU study has three components: (i) a physician survey to describe their management of osteoporotic patients with GI events; (ii) a retrospective chart survey to describe the receipt and type of osteoporosis medication prescribed; and (iii) a prospective cohort study including untreated and treated patients diagnosed with osteoporosis to investigate the rate of GI events and association with osteoporosis medication use patterns, health-related quality of life, treatment satisfaction and resource utilisation among postmenopausal women with osteoporosis. Physicians at 97 sites completed the physician questionnaire and data for 716 patients were abstracted for the retrospective chart review. Enrolment and the baseline data collection for the prospective cohort study were conducted between March 2012 and June 2013 for 292 untreated and 2,959 treated patients, of whom 684 were new users and 2,275 were experienced users of oral osteoporosis medications. The results of MUSIC OS-EU will illuminate the association of GI events with the management of osteoporosis and with patient-reported outcomes among postmenopausal women with osteoporosis in Europe and Canada.

    Background: Periodontal pathogens have been isolated from precancerous and cancerous lesions and also shown to promote a procarcinogenic microenvironment. Few studies have examined periodontal disease as a risk factor for total cancer, and none have focused on older women. We examined whether periodontal disease is associated with incident cancer among postmenopausal women in the Women's Health Initiative Observational Study. Methods: Our prospective cohort study comprised 65,869 women, ages 54 to 86 years. Periodontal disease information was obtained via self-report questionnaires administered between 1999 and 2003, whereas ascertainment of cancer outcomes occurred through September 2013, with a maximum follow-up period of 15 years. Physician-adjudicated incident total cancers were the main outcomes and site-specific cancers were secondary outcomes. HRs and 95% confidence intervals (CI) were calculated using Cox proportional hazards regression. All analyses were conducted two-sided. Results: During a mean follow-up of 8.32 years, 7,149 cancers were identified. Periodontal disease history was associated with increased total cancer risk (multivariable-adjusted HR, 1.14; 95% CI, 1.08-1.20); findings were similar in analyses limited to 34,097 never-smokers (HR, 1.12; 95% CI, 1.04-1.22). Associations were observed for breast (HR, 1.13; 95% CI, 1.03-1.23), lung (HR, 1.31; 95% CI, 1.14-1.51), esophagus (HR, 3.28; 95% CI, 1.64-6.53), gallbladder (HR, 1.73; 95% CI, 1.01-2.95), and melanoma skin (HR, 1.23; 95% CI, 1.02-1.48) cancers. Stomach cancer was borderline (HR, 1.58; 95% CI, 0.94-2.67). Conclusions: Periodontal disease increases risk of total cancer among older women, irrespective of smoking, and certain anatomic sites appear to be vulnerable. Impact: Our findings support the need for further understanding of the effect of periodontal disease on cancer outcomes.

    Full Text Available Alain MonnierInstitut Régional Fédératif du Cancer (IFRC, Centre Hospitalier Belfort-Montbéliard, Montbéliard, FranceAbstract: Aromatase inhibitors (AIs are becoming more widely used than tamoxifen as adjuvant hormonal therapy for postmenopausal women (PMW with early breast cancer (EBC. It is clear that these drugs offer important efficacy benefits over tamoxifen and differ from tamoxifen in their safety profile. The accepted strategies for adjuvant AI therapy include initial adjuvant treatment following surgery, switching and/or sequencing from prior tamoxifen, and extended adjuvant therapy following the full 5 years of tamoxifen treatment. Among the available AIs, letrozole has been evaluated in large, well-controlled, double-blind clinical trials in the initial adjuvant, extended adjuvant, and more recently, the sequential adjuvant settings. Letrozole is the most potent of the AIs and provides near complete suppression of plasma estrogens in PMW. Letrozole also significantly reduces the occurrence of early distant metastases, the most lethal type of recurrence event, which can lead to improved survival. Clinical comparisons of letrozole with both tamoxifen and placebo have also provided important long-term safety data on the use of AIs as adjuvant therapy in PMW with EBC. The weight of clinical evidence indicates that letrozole is a safe and effective option for adjuvant hormonal therapy across all three AI treatment settings.Keywords: aromatase inhibitor, breast cancer, hormonal therapy, letrozole, postmenopausal women, tamoxifen

  4. Managing arthralgia in a postmenopausal woman taking an aromatase inhibitor for hormonesensitive early breast cancer: a case study

    In order to reduce the risk of recurrence, adjuvant treatment with an aromatase inhibitor (AI) is recommended for postmenopausal women following surgery for hormone receptor-positive breast cancer. AIs are associated with improved disease-free survival compared with tamoxifen. The adverse events associated with AIs resemble those of menopause, such as bone density loss and musculoskeletal symptoms. We examine the case of a postmenopausal woman who was prescribed anastrozole, a nonsteroidal AI, as adjuvant therapy following surgery for estrogen and progesterone receptor-positive (ER and PgR+) breast cancer. A 58-year-old postmenopausal woman diagnosed with ER and PgR+ breast cancer was prescribed anastrozole as adjuvant therapy following a right-inferior quadrantectomy. After experiencing joint pain and stiffness, she was prescribed paracetamol and a topical nonsteroidal anti-inflammatory drug. She was also counseled on nonpharmacological interventions. However, she continued to experience symptoms, and reported that she was not taking anastrozole regularly. The case study patient ultimately found relief by switching to letrozole, another aromatase inhibitor. This approach is supported by recent studies examining the benefits of switching strategies between aromatase inhibitors in order to relieve symptoms of arthralgia/myalgia. Both adherence and strategies for managing aromatase inhibitor-associated arthralgia are key to deriving maximal clinical benefit from AI therapy. Switching from one aromatase inhibitor to another may provide a viable option in managing adverse events and enhancing adherence to medication

    Full Text Available Objective. To evaluate patients’ health status and the course of endometriosis from the premenopausal to the postmenopausal period and evaluate influencing factors that may be relevant. Methods. Questionnaire completed by 35 postmenopausal women in whom endometriosis had been histologically confirmed premenopausally. Correlation and regression analyses were carried out to identify factors relevant to their postmenopausal health status. Results. Overall, there was clear improvement in typical endometriosis symptoms and sexual life. Clear associations (P<0.005 were observed between premenopausal factors like physical limitations caused by the disease, impaired social contacts and psychological problems, and postmenopausal pain and impairment of sexual life. Three statistical models for assessing pain and impairment of sexual life in the postmenopausal period were calculated on the basis of clinical symptoms in the premenopausal period, with a very high degree of accuracy (P<0.001; R2 = 0.833/0.857/0.931. Conclusions. The results of the survey strongly suggest that physical fitness and freedom from physical restrictions, a good social environment, and psychological care in both the premenopausal and postmenopausal periods lead to marked improvements in the postmenopausal period with regard to pain, dyspareunia, and influence on sexual life in endometriosis patients.

    How physical activity (PA) and sitting time may change after first myocardial infarction (MI) and the association with mortality in postmenopausal women is unknown. Participants included postmenopausal women in the Women's Health Initiative-Observational Study, aged 50 to 79 years who experienced a clinical MI during the study. This analysis included 856 women who had adequate data on PA exposure and 533 women for sitting time exposures. Sitting time was self-reported at baseline, year 3, and year 6. Self-reported PA was reported at baseline through year 8. Change in PA and sitting time were calculated as the difference between the cumulative average immediately following MI and the cumulative average immediately preceding MI. The 4 categories of change were: maintained low, decreased, increased, and maintained high. The cut points were ≥7.5 metabolic equivalent of task hours/week versus sitting time. Cox proportional hazard models estimated hazard ratios and 95% CIs for all-cause, coronary heart disease, and cardiovascular disease mortality. Compared with women who maintained low PA (referent), the risk of all-cause mortality was: 0.54 (0.34-0.86) for increased PA and 0.52 (0.36-0.73) for maintained high PA. Women who had pre-MI levels of sitting time sitting time was associated with a 9% increased risk (hazard ratio=1.09, 95% CI: 1.01, 1.19) of all-cause mortality. Meeting the recommended PA guidelines pre- and post-MI may have a protective role against mortality in postmenopausal women. © 2017 The Authors.

    Several factors may increase fracture risk, among them reduced bone mineral density (BMD), increased bone resorption, microarchitectural deterioration of bone, increased fall risk, and decreased muscle strength. We have previously reported that PvuII polymorphism of the estrogen receptor-alpha (ER alpha) gene is associated with bone loss rate, fracture risk, and response to hormone replacement therapy (HRT) in early postmenopausal Finnish women. We studied the influence of the ER alpha genotype on fall risk and muscle strength in a 5-year randomized HRT trial of 331 early postmenopausal women (subgroup of the population-based OSTPRE study, Kuopio, Finland). A 5-year postal inquiry in May 1994 included questions on falls during the previous 12 months. Grip strength was measured with dynamometer. The ER alpha gene polymorphism was analysed using PCR and PvuII restriction enzyme digestion. RESULTS. In all, 97 out of the 331 women reported falls. Half of those (56%) were slip falls, mostly during the winter season. In the HRT group, the ER alpha genotype was associated with fall risk (P = 0.002, logistic regression). The risk of falls (RR) was higher in women with the PP genotype than in those with the Pp (RR = 5.26, 95% CI 1.98-13.94, P = 0.001) or the pp (RR = 3.84, 95% CI 1.46-10.12, P = 0.007) genotype. When the falls were divided into slip (environment-related) and non-slip (endogenous) falls, the non-slip falls were associated with the genotype (P = 0.004), but the slip falls were not so clearly (P = 0.061). When all falls and non-slip falls were adjusted to the number of chronic health disorders and the variable time-since-menopause, the difference between the genotypes persisted (P = 0.003 and P = 0.010, respectively). In the non-HRT group, the ER alpha genotype was not associated with fall risk. The baseline or the 5-year grip strength values were not influenced by the ER alpha genotype. In conclusion, ER alpha polymorphism is associated with fall risk

  10. Early Observations of Sunspots: Scheiner and Galileo

    Science.gov (United States)

    Casanovas, J.

    There had been occasional observations of spots on the Sun since antiquity. Kepler observed a sunspot in 1607 but he interpreted it as a Mercury's transit. One year after the introduction of the telescope astronomers identified spots on the Sun. J. Fabricius was the first to print a book on sunspots at the end of 1611, but this book had little diffusion. Fabricius rightly thought that the spots belonged to the Sun. The Jesuit C. Scheiner independently observed sunspots on the Sun and he announced his discovery at the end of 1611 in three letters under the pseudonym Apelles. Scheiner failed to observe the returning of the spots and hence did not recognize the solar rotation. Therefore he preferred to see the spots as caused by little bodies orbiting the Sun. Based on Scheiner's observations, Kepler concluded that the spots were on the solar surface like dross floating on melted metal. When Scheiner's letters reached Italy, Galileo claimed to have observed sunspots much earlier, but if this had been the case, he had not published anything on sunspots. Galileo replied to Apelles' letters affirming that the spots were on the surface of the Sun, like clouds. A bitter and long fight followed between Galileo and Scheiner on the priority of discovery. Techniques for solar observation progressed quickly. The solar image was observed projected on a white paper for measurement of sunspots positions. Scheiner later perfected this method installing the telescope on an equatorial mounting. Scheiner made over 2000 solar observations and determined the orientation of the solar axis of rotation. His methods and results were presented in his monumental work Rosa Ursina.

    Osteoporotic fractures are important causes of morbidity, mortality, and increased health care costs. However, the risk of osteoporotic fractures can be decreased, with clinical studies supporting the use of calcium and vitamin D supplements to promote bone health. Vitamin D insufficiency is widespread, particularly among postmenopausal women with osteoporosis, and this indicates that dietary intake is suboptimal, even though vitamin D supplements are widely available. We conducted an observational study, using telephone surveys, to estimate vitamin D and calcium intake and the use of prescription osteoporosis medications in Spanish women aged ≥ 50 years with osteoporosis. Among the study participants, mean dietary calcium intake was 1239 mg/day and generally appeared sufficient in terms of the recommended daily intake guidance documents. Participants aged ≥ 75 years had a significantly lower mean dietary calcium intake (988 mg/day), thus one-half were below the level advised by the World Health Organization. Daily calcium intake was also lower in participants who were not taking prescription medications for bone health. Dietary vitamin D intake was 167 IU/day, which is well below both the established target dose (400 IU/day) and the more recent, higher guideline recommended for postmenopausal women (800-1300 IU/day). Dietary vitamin D intake was even lower for participants aged ≥ 75 years (120 IU/day) and was not related to the use of bone health prescription medications. These results support the need for greater promotion of the benefits of higher vitamin D intake in Spanish women with osteoporosis.

Dietary vitamin D intake was 167 IU/day, which is well below both the established target dose (400 IU/day and the more recent, higher guideline recommended for postmenopausal women (800–1300 IU/day. Dietary vitamin D intake was even lower for participants aged ≥75 years (120 IU/day and was not related to the use of bone health prescription medications. Conclusion: These results support the need for greater promotion of the benefits of higher vitamin D intake in Spanish women with

    Growing evidence indicates that physical exercise can prevent at least some of the negative effects on health associated with early menopause. Here we determine the effects of intense exercise on physical fitness, bone mineral density (BMD), back pain, and blood lipids in early postmenopausal women. The study population comprised 50 fully compliant women, with no medication or illness affecting bone metabolism, who exercised over 26 months (exercise group [EG]), and 33 women who served as a nontraining control group (CG). Two group training sessions per week and 2 home training sessions per week were performed in the EG. Both groups were individually supplemented with calcium and cholecalciferol. Physical fitness was determined by maximum strength and cardiovascular performance. Bone mineral density was measured at the lumbar spine (dual-energy x-ray absorptiometry [DXA] and quantitative computed tomography [QCT]), the proximal femur (DXA), and the forearm (DXA). In serum samples taken from a subset of the study participants, we determined bone formation (serum osteocalcin) and resorption (serum cross-links) markers as well as blood lipid levels. Vasomotor symptoms related to menopause and pain were also assessed. After 26 months, significant exercise effects determined as percentage changes compared with baseline were observed for physical fitness (isometric strength: trunk extensors [EG +36.5% vs CG +1.7%], trunk flexors [EG +39.3% vs CG -0.4%], and maximum oxygen consumption [EG +12.4% vs CG -2.3%]); BMD (lumbar spine [DXA L1-L4, EG +0.7% vs CG -2.3%], QCT L1-L3 trabecular region of interest [EG +0.4% vs CG -6.6%], QCT L1-L3 cortical region of interest [EG +3.1% vs CG -1.7%], and total hip [DXA, EG -0.3% vs CG -1.7%]); serum levels (total cholesterol [EG -5.0% vs CG +4.1%] and triglycerides [EG -14.2% vs CG +23.2%]); and pain indexes at the spine. General purpose exercise programs with special emphasis on bone density can significantly improve strength and

  15. Effective osteoporosis treatment with teriparatide is associated with enhanced quality of life in postmenopausal women with osteoporosis: the European Forsteo Observational Study

    Science.gov (United States)

    2013-01-01

    Background To describe changes in health-related quality of life (HRQoL) of postmenopausal women with osteoporosis treated with teriparatide for up to 18 months and followed-up for a further 18 months, and to assess the influence of recent prior and incident fractures. Methods The European Forsteo Observational Study (EFOS) is an observational, prospective, multinational study measuring HRQoL using the EQ-5D. The primary objective was to assess changes in HRQoL during 36 months in the whole study population. A secondary post-hoc analysis examined fracture impact on HRQoL in four subgroups classified based on recent prior fracture 12 months before baseline and incident clinical fractures during the study. Changes from baseline were analysed using a repeated measures model. Results Of the 1581 patients, 48.4% had a recent prior fracture and 15.6% of these patients had an incident fracture during follow-up. 10.9% of the 816 patients with no recent prior fracture had an incident fracture. Baseline mean EQ-VAS scores were similar across the subgroups. In the total study cohort (n = 1581), HRQoL (EQ-VAS and EQ-5D index scores) improved significantly from baseline to 18 months and this improvement was maintained over the 18-month post-teriparatide period. Improvements were seen across all five EQ-5D domains during teriparatide treatment that were maintained after teriparatide was discontinued. Subjects with incident clinical fractures had significantly less improvement in EQ-VAS than those without incident fractures. Recent prior fracture did not influence the change in EQ-VAS during treatment. Conclusions EFOS is the first longitudinal study in women with severe postmenopausal osteoporosis in the real world setting to show a substantial improvement in HRQoL during teriparatide treatment that was sustained during subsequent treatment with other medications. The increase in HRQoL was lower in the subgroups with incident fracture but was not influenced by recent prior

Synergistic muscle activation intensifies a woman’s ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM during resting and functional PFM activation in postmenopausal women with and without SUI.Materials and methods: This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland.

    Objectives To describe fracture rates, back pain, and health-related quality of life (HRQoL) in postmenopausal women with osteoporosis and prior bisphosphonate therapy, treated with teriparatide for up to 18 months and followed up for a further 18 months. Design Prospective, multinational, and observational study. Methods Data on prior bisphosphonate use, clinical fractures, back pain visual analog scale (VAS), and HRQoL (EQ-5D) were collected over 36 months. Fracture data were summarized in 6-month intervals and analyzed using logistic regression with repeated measures. Changes from baseline in back pain VAS and EQ-VAS were analyzed using a repeated measures model. Results Of the 1581 enrolled patients with follow-up data, 1161 (73.4%) had a history of prior bisphosphonate use (median duration: 36 months). Of them, 169 (14.6%) sustained ≥1 fracture during 36-month follow-up. Adjusted odds of fracture were significantly decreased at each 6-month interval compared with the first 6 months of teriparatide treatment: 37% decrease in the 12 to teriparatide treatment (P=0.03) and a 76% decrease in the 12- to 18-month period after teriparatide was discontinued (Pteriparatide treatment. These outcomes were still evident for at least 18 months after teriparatide was discontinued. The results should be interpreted in the context of an uncontrolled, observational study in a routine clinical setting. PMID:22048967

    The objective of the study was to evaluate the association of depression, sleep disturbance, and menopausal symptoms with diminished libido. Data from a 2001-2002 baseline survey of 341 peri- and postmenopausal women, aged 45-55 years, participating in a randomized trial, was analyzed. Eligibility included at least 2 hot flashes and/or night sweats per day and no hormone therapy for at least the prior 3 months. The survey evaluated sexual function, depression, sleep, and vasomotor symptoms. We examined the association between these factors, using multivariate regression models. Of 341 women, 64% had diminished libido, 18% had moderate to severe depression, and 43% had poor sleep quality. Women averaged 4.6 hot flashes and 1.9 night sweats per day. Depressive symptoms (P = .003), poor sleep (P = .02), and night sweats (P = .04) were significantly associated with diminished libido. Factors associated with diminished libido in midlife are complex but include depression, disturbed sleep, and night sweats, all common symptoms of the menopausal transition and early menopause.

    Full Text Available Objectives. We aim to determine the efficacy of bisphosphonates in preventing aromatase inhibitor induced bone loss (AIBL in postmenopausal women with early breast cancer. The secondary objective was to determine the safety of bisphosphonates. Materials and Methods. We searched electronic databases in a time period of 1995 January to 2013 June. Random effects meta-analytical models were used; between study heterogeneity and publication bias was assessed. Results. A total of six eligible studies reported the BMD T score of LS at 12 months and from that 3 trials of Zoledronic acid compared the change in BMD in immediate ZOL versus delayed ZOL done with subgroups like patients with normal BMD at baseline (OR = 5.402, 95% CI = 1.329–21.959, P value = 0.018 and osteopenic BMD at baseline (OR = 4.008, 95% CI = 2.249–7.143, P value = 0.0002. Both had a significant decrease in BMD that favoured the delayed ZOL; 3 trials of risedronate and ibandronate also had a significant decrease in BMD in AIs alone group. Immediate ZOL versus delayed ZOL also showed increased risk of getting an ADR in immediate group. Conclusion. Third generation bisphosphonates has an effect on BMD of patients who are on treatment of AIs in breast cancer. Furthermore, the patients treated with immediate ZOL had a significantly high risk of musculoskeletal ADR’s than patients with delayed ZOL.

    The antiestrogen tamoxifen may have partial estrogen-like effects on the postmenopausal uterus. Aromatase inhibitors (AIs) are increasingly used after initial tamoxifen in the adjuvant treatment of postmenopausal early breast cancer due to their mechanism of action: a potential benefit being a reduction of uterine abnormalities caused by tamoxifen. Sonographic uterine effects of the steroidal AI exemestane were studied in 219 women participating in the Intergroup Exemestane Study: a large trial in postmenopausal women with estrogen receptor-positive (or unknown) early breast cancer, disease free after 2-3 years of tamoxifen, randomly assigned to continue tamoxifen or switch to exemestane to complete 5 years adjuvant treatment. The primary end point was the proportion of patients with abnormal (> or =5 mm) endometrial thickness (ET) on transvaginal ultrasound 24 months after randomisation. The analysis included 183 patients. Two years after randomisation, the proportion of patients with abnormal ET was significantly lower in the exemestane compared with tamoxifen arm (36% versus 62%, respectively; P = 0.004). This difference emerged within 6 months of switching treatment (43.5% versus 65.2%, respectively; P = 0.01) and disappeared within 12 months of treatment completion (30.8% versus 34.7%, respectively; P = 0.67). Switching from tamoxifen to exemestane significantly reverses endometrial thickening associated with continued tamoxifen.

    The aim of this study was to evaluate retrospectively the usefulness of transvaginal sonography for the detection of endometrial disease in postmenopausal women without symptoms. The study involved 750 postmenopausal women aged 52-65 (mean 58.5). None of them were on hormone replacement therapy and all had had amenorrhea for more than two years. Transvaginal sonography was performed in 750 women. An endometrium of women) was not investigated further. The 627 cases of this group were reassessed one year later. In the remaining 123 postmenopausal women with suspicious endometrium > 5 mm, 19 endometrial polyps (7.13%), one cervical polyp with extension in the cavity (0.8%), 90 endometrial atrophies (73.17%), ten atrophic endometritis (8.13%), two simple hyperplasias (1.62%), and one hyperplasia with atypia (0.8%) were found. Transvaginal sonography is an efficient and acceptable noninvasive method for the early detection of endometrial pathology in postmenopausal asymptomatic women.

    Muscles such as adductor magnus (AM), gluteus maximus (GM), rectus abdominis (RA), and abdominal external and internal oblique muscles are considered to play an important role in the treatment of stress urinary incontinence (SUI), and the relationship between contraction of these muscles and pelvic floor muscles (PFM) has been established in previous studies. Synergistic muscle activation intensifies a woman's ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM) during resting and functional PFM activation in postmenopausal women with and without SUI. This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland. Forty-two patients participated in the study and were screened for eligibility criteria. Thirty participants satisfied the criteria and were categorized into two groups: women with SUI (n=16) and continent women (n=14). The bioelectrical activity of PFM and SPFM (AM, RA, GM) was recorded with a surface electromyographic instrument in a standing position during resting and functional PFM activity. Bioelectrical activity of RA was significantly higher in the incontinent group than in the continent group. These results concern the RA activity during resting and functional PFM activity. The results for other muscles showed no significant difference in bioelectrical activity between groups. In women with SUI, during the isolated activation of PFM, an increased synergistic activity of RA muscle was observed; however, this activity was not observed in asymptomatic women. This may indicate the important accessory contribution of these muscles in the mechanism of continence.

    The study analyses the performances of FRAX algorithm and quantitative ultrasound (QUS) tool in relationship to the dual-energy X-ray absorptiometry (DXA) categorization to identify patients at risk of osteoporosis during menopause and to reach new thresholds for recommending the first DXA examination. Retrospective cohort study. Two hundred eighty-two postmenopausal patients filled out a questionnaire which determined their FRAX index and performed a bone evaluation by QUS of the calcaneus to determine their stiffness index (SI). Thereafter, they underwent assessments by the gold-standard DXA bone examination. Statistically significant correlations were observed between FRAX (calculated without BMD) and both QUS and DXA diagnosis. FRAX mean indices of risk corresponding to the diagnosis of osteoporosis by QUS and DXA were similar. Receiver operating characteristic (ROC) curve analysis showed that both FRAX and QUS tests were sufficiently accurate in predicting the alteration of bone mineral composition. The ROC curves of QUS allowed us to identify, in our population, SI cutoff for normal patients (SI > 90.5) and for patients having osteoporosis (SI related to the bone status of the patient.

    This is the second, conclusive part of the clinical study on clinical responses of early-postmenopausal women to standardized doses of pre-Gelatinized Organic Maca (Maca-GO). Total of 34 Caucasian women volunteers participated in a double-blind, randomized, four months outpatient crossover configuration Trial. After fulfilling the criteria of being early-postmenopausal: blood Estrogen (E230 IU/ml) at admission, they were randomly allocated to Placebo (P) and Maca-GO (M) treatments (2 groups of 11 participants each). Two 500 mg vegetable hard gel capsules with Maca-GO or Placebo powder were self-administered twice daily with meals (total 2 g/day). At admission and follow-up monthly intervals, body mass index (BMI), blood pressure, levels of gonadal, pituitary, thyroid and adrenal hormones, lipids and key minerals were measured. Bone markers were determined after four months M and P use in 12 participants. Menopausal symptoms were assessed according to Greene's Score (GMS) and Kupperman's Index (KMI). Data were analyzed using multivariate technique on blocs of monthly. Results and canonical variate technique was applied to GMS and KMI matrices. Two months application of Maca-GO stimulated (PMaca-GO noticeably increased bone density markers. In conclusion, Maca-GO applied to early-postmenopausal women (i) acted as a toner of hormonal processes along the Hypothalamus-Pituitary-Ovarian axis, (ii) balanced hormone levels and (iii) relieved symptoms of menopausal discomfort, (hot flushes and night sweating in particular), thus, (iv) exhibited a distinctive function peculiar to adaptogens, providing an alternative non-hormonal plant option to reduce dependence on hormone therapy programs (HRT).

    The purpose of the present study was to evaluate the utility of hysteroscopy as a diagnostic tool in cases of postmenopausal bleeding. The study includes 42 cases presenting with postmenopausal bleeding on which hysterscopy was performed using rigid hysteroscope (CIRCON) with glycine 1.5% as the distension medium. In 17 of the 42 cases positive hysteroscopic findings were noted which included 2 cases of endometrial carcinoma, 2 cases of postmenopausal endometritis, 4 cases of endometrial polyp, 5 cases of endometrial hyperplasia, 1 case of submucous myoma and 3 cases of endocervical polyp whereas normal postmenopausal endometrium was noticed in rest of the 25 cases. Endometrial biopsy was done in all these cases so that the hysteroscopic findings could be corroborated with tissue diagnosis. Hysteroscopy along with directed endometrial biopsy proved to be a useful diagnostic aid in cases of postmenopausal bleeding.

    The RAPid Telescopes for Optical Response (RAPTOR) system at Los Alamos National Laboratory observed GRB 050319 starting 25.4 s after γ-ray emission triggered the Burst Alert Telescope (BAT) on board the Swift satellite. Our well-sampled light curve of the early optical afterglow is composed of 32 points (derived from 70 exposures) that measure the flux decay during the first hour after the GRB. The GRB 050319 light curve measured by RAPTOR can be described as a relatively gradual flux decline (power-law index α=-0.38) with a transition, at about ~400 s after the GRB, to a faster flux decay (α=-0.91). The addition of other available measurements to the RAPTOR light curve suggests that another emission component emerged after ~104 s. We hypothesize that the early afterglow emission is powered by extended energy injection or delayed reverse-shock emission followed by the emergence of forward-shock emission.

    2012-02-03

    One goal of osteoporosis research is to identify the genes and environmental factors that contribute to low bone mineral density (BMD) and fracture. Linkage analyses have identified quantitative trait loci (QTLs), however, the genes contributing to low BMD are largely unknown. We examined the potential association of an intronic polymorphism in CD38 with BMD and postmenopausal bone loss. CD38 resides in 4p15, where a QTL for BMD has been described. CD38-\\/- mice display an osteoporotic phenotype at 3 months, with normalization of BMD by 5 months. The CD38 polymorphism was identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 457 postmenopausal and 173 premenopausal Caucasian women whose spine and hip BMD was measured by dual energy X-ray absorptiometry (DXA). Influence of the CD38 polymorphism on bone loss was analyzed in 273 postmenopausal women over a follow-up of 2.94 +\\/- 1.50 years. The CD38-PvuII polymorphism was significantly associated with premenopausal and postmenopausal (P = 0.001) lumbar spine BMD. Women homozygous for the G allele had >14% lower spinal BMD than women with GC\\/CC genotypes. An allele dose effect was observed at the spine in premenopausal (P = 0.002) and postmenopausal (P < 0.001) cohorts. The CD38-PvuII polymorphism was significantly associated with femoral neck BMD in pre- and postmenopausal women (P = 0.002 and P = 0.011, respectively). However, significance was lost following adjustment of hip BMD for covariates in the postmenopausal cohort (P = 0.081). The CD38-PvuII polymorphism was weakly associated with bone loss at the spine (P = 0.024), in postmenopausal women not taking hormone replacement therapy. We suggest that the CD38-PvuII polymorphism may influence the attainment and maintenance of peak BMD and postmenopausal bone loss.

    As an integrated observing strategy, the concept of sensorweb for Earth observations is appealing in many aspects. For instance, by increasing the spatial and temporal coverage of observations from space and other vantage points, one can eventually aid in increasing the accuracy of the atmospheric models which are precursor to hurricane track prediction, volcanic eruption forecast, and trajectory path of transcontinental transport of dust, harmful nuclear and chemical plumes. In reality, there is little analysis'available in terms of benefits, costs and optimized set of sensors needed to make these necessary observations. This is a complex problem that must be carefully studied and balanced over many boundaries such as science, defense, early warning security, and surveillance. Simplistically, the sensorweb concept from the technological point of view alone has a great appeal in the defense, early warning and security applications. In fact, it can be relatively less expensive in per unit cost as opposed to building and deploying it for the scientific use. However, overall observing approach should not be singled out and aligned somewhat . orthogonally to serve a particular need. On the other hand, the sensorweb should be designed and deployed to serve multiple subject areas and customers simultaneously; and can behave as directed measuring systems for both science and operational entities. Sensorweb can be designed to act as expert systems, and/or also provide a dedicated integrated surveillance network. Today, there is no system in the world that is fully integrated in terms of reporting timely multiple hazards warnings, computing the lass of life and property damage estimates, and is also designed to cater to everyone's needs. It is not an easier problem to undertake and more so is not practically solvable. At this time due to some recent events in the world, the scientific community, social scientists, and operational agencies are more cognizant and getting

    Full Text Available In diagnostic of osteoporosis the golden standard is bone mineral density, though X-ray densitomenry parameters not always determine risk for osteoporotic fractures. That is why new methods are being looked for to find the parameters not only mineral density, but rather quantity of bone. One of theses methods is trabecular bone score. As general weight of body includes fat and lean mass some researchers tried to determine their role in development of structural and functional impairments in bone, however there is no clear answer to this question: while some scientists considered fat mass as a basic factor of protection from fractures, other ones decided that lean mass is more connected with mineral density of bone tissue. The aim of study was to investigate parameters of quantity and density of bone of spine, neck of femur and body composition depending on the postmenopausal period; to study connection between fat mass and mineral density and quantity of bone. Materials and methods. The observed females were divided into the groups: premenopausal women and women with postmenopause of various duration (early, middle, late. There were conducted a general clinical observation of a patient and investigation of mentioned above parameters using X-ray densitomentry General Electric. Results. Quantity of bone (TBS and bone mineral density significantly decrease depending on postmenopausal period. Fat and lean masses do not significantly change. In the middle and late postmenopausal periods bone mineral density of the spine and hip neck increase while fat mass increases.

Servei de Medicina Reproductiva and Centre d'Investigacions en Bioquimica i Biologia Molecular, Hospitals Vall d'Hebron, Barcelona, Spain. Six premenopausal women and four postmenopausal women undergoing bilateral oophorectomy for nonovarian gynecologic disease. Extraction of 10 mL of peripheral venous blood for hormone measurements. Extraction of RNA from surgically removed ovaries for Northern blot, ribonuclease protection, and reverse transcriptase polymerase chain reaction Southern blot assays. Definition of the reproductive cycle state of each patient and determination of the level of P450c17 gene expression in all samples with the use of the semiquantitative reverse transcriptase polymerase chain reaction Southern blot assay. P450c17 messenger RNA levels in postmenopausal ovaries varied considerably between samples. Although the levels were similar to those detected in the early follicular phase, one of the samples had levels as high as those observed in the late follicular phase. Although the degree varied from one sample to another, all the postmenopausal ovaries studied expressed the P450c17 gene at the messenger RNA level. In a sample from a patient with endometrial adenocarcinoma, the level was as high as the levels observed in the late follicular phase.

    In the first decades of the 20{sup th} century, aerological observations were for the first time performed in tropical regions. One of the most prominent endeavours in this respect was Arthur Berson's aerological expedition to East Africa. Although the main target was the East African monsoon circulation, the expedition provided also other insights that profoundly changed meteorology and climatology. Berson observed that the tropical tropopause was much higher and colder than that over midlatitudes. Moreover, westerly winds were observed in the lower stratosphere, apparently contradicting the high-altitude equatorial easterly winds that were known since the Krakatoa eruption ('Krakatoa easterlies'). The puzzle was only resolved five decades later with the discovery of the Quasi-Biennial Oscillation (QBO). In this paper we briefly summarize the expedition of Berson and review the results in a historical context and in the light of the current research. In the second part of the paper we re-visit Berson's early aerological observations, which we have digitized. We compare the observed wind profiles with corresponding profiles extracted from the 'Twentieth Century Reanalysis', which provides global three-dimensional weather information back to 1871 based on an assimilation of sea-level and surface pressure data. The comparison shows a good agreement at the coast but less good agreement further inland, at the shore of Lake Victoria, where the circulation is more complex. These results demonstrate that Berson's observations are still valuable today as input to current reanalysis systems or for their validation. (orig.)

  1. Assessment of Postmenopausal Bleeding

    Full Text Available Postmenopausal bleeding is bleeding that occurs 12 or more months after the last menstrual period and accounts for 5% of all gynecologic office visits. While it is not always a symptom of cancer, the exclusion of endometrial hyperplasia and carcinoma is the key issue in the evaluation of patients with postmenopausal bleeding. The primary evaluation of postmenopausal women who present with abnormal uterine bleeding includes a medical history and a pelvic examination. Investigative studies, such as a uterine biopsy, ultrasound, hysteroscopy or dilation and curettage, may be required. Treatment will depend on the cause determined. The most important point is that irregular perimenopausal or postmenopausal bleeding should not be ignored or assumed to be a normal phenomenon.

    [Purpose] The aim of the present study was to assess the influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women. [Subjects and Methods] This was an observational analytic cross-sectional study with a sample of 100 postmenopausal women, aged between 45 and 65 years, divided into three groups according to menopausal stage: hysterectomized and early and late postmenopause. Patients were assessed for sociodemographic and gyneco-obstetric factors and subjected to a muscle strength test and perineometry. Descriptive statistics, ANOVA, Kruskal-Wallis and multiple regression were applied. [Results] The results showed homogeneity in sociodemographic and anthropometric characteristics. There was no difference in pelvic floor muscle function among the three groups. Type of delivery, parity and physical activity level showed no influence on muscle function. [Conclusion] The findings demonstrate that parity, type of delivery, and physical activity level had no influence on pelvic floor muscle pressure in postmenopausal women. One hypothesis to explain these results is the fact that the decline in muscle function in postmenopausal women is related to the female aging process.

  3. Assessment of periodontal health status in postmenopausal women visiting dental hospital from in and around Meerut city: Cross-sectional observational study

    D Deepa

    2016-01-01

    Full Text Available Background: Puberty, menses, pregnancy, and menopause are the different phases of a woman′s life which have a varied influence on oral health. During the menopause, women go through biological and endocrine changes, particularly in their sex steroid hormone production which affects their health. Because the oral mucosa contains estrogen receptors, variations in hormone levels can be seen directly in the oral cavity leading to a few oral conditions and diseases seen more frequently during postmenopausal years. Objective: The objective of this study is to assess periodontal health status in postmenopausal women in and around Meerut city. Materials and Methods: The study sample comprised ninety postmenopausal women. History of menopause was recorded, and the dental examinations were done by measuring the following parameters of periodontal health: plaque index (PI, gingival index (GI, bleeding on probing (BOP, pocket probing depth, and Russell′s periodontal index. The collected data were subjected to statistical analyses. Results and Conclusion: In the study group, mean age was 55 years, mean missing teeth were 10.3, mean duration of menopause was 9.23. Eleven percent females were completely edentulous, and 5 females had never brushed. Mean PI-s was 1.99, mean GI-s was 1.74, mean BOP was 52.85, and mean Russell′s periodontal index was 4.34. Eleven patients were at the initial stages of destructive periodontal disease, 34 had established destructive periodontal disease while thirty patients had the terminal periodontal disease. These findings suggest that females after menopause are at a risk of developing destructive periodontal disease if proper oral hygiene practices are not followed.

    Full Text Available A significant open issue in cloud computing is the real performance of the infrastructure. Few, if any, cloud providers or technologies offer quantitative performance guarantees. Regardless of the potential advantages of the cloud in comparison to enterprise-deployed applications, cloud infrastructures may ultimately fail if deployed applications cannot predictably meet behavioral requirements. In this paper, we present the results of comprehensive performance experiments we conducted on Windows Azure from October 2009 to February 2010. In general, we have observed good performance of the Windows Azure mechanisms, although the average 10 min VM startup time must be accounted for in application design. We also present performance and reliability observations and analysis from our deployment of a large-scale scientific application hosted on Azure, called ModisAzure, that show unusual and sporadic VM execution slowdown of over 4× in some cases and affected up to 16% of task executions at times. In addition to a detailed performance evaluation of Windows Azure, we provide recommendations for potential users of Windows Azure based on these early observations. Although the discussion and analysis is tailored to scientific applications, the results are broadly applicable to the range of existing and future applications running in Windows Azure.

    This was a double-blind, randomized, placebo-corrected, outpatient, multi-centre (five sites) clinical study, in which a total of 168 Caucasian early-postmenopausal women volunteers (age>49 years) participated after fulfilling the criteria: follicle stimulating hormone (FSH) >30 IU/ml and estrogen (E2) Maca (Maca-GO) treatment, according to different monthly treatment sequences scheduled for each site. Two 500 mg vegetable hard gel capsules with Maca-GO or Placebo powder were self-administered twice daily with meals (total 2 g/day) during three (Trial I; n=102) or four (Trial II; n=66) months study periods. At the baseline and follow- up monthly intervals, blood levels of FSH, E2, progesterone (PRG) and lutinizing hormone (LH), as well as serum cholesterol (CHOL), triglycerides (TRG), high- and low density lipoproteins (HDL and LDL) were measured. Menopausal symptoms were assessed according to Greene's Score (GMS) and Kupperman's Index (KMI). Data were analyzed using multivariate technique on blocs of monthly results in one model and Maca versus Placebo contrast in another model. A total of 124 women concluded the study. Maca-GO significantly stimulated production of E2 (PMaca-GO significantly reduced both frequency and severity of individual menopausal symptoms (hot flushes and night sweating in particular) resulting in significant (P<0.001) alleviation of KMI (from 22 to 10), thus, offering an attractive non-hormonal addition to the choices available to early-postmenopausal women in the form of a natural plant alternative to Hormone Replacement Therapy (HRT) - hence, reducing dependence on hormone therapy programs.

    The burden of osteoporosis in the Asia-Pacific region is not well characterized. The Medication Use Patterns, Treatment Satisfaction, and Inadequate Control of Osteoporosis Study in the Asia-Pacific Region (MUSIC OS-AP) was designed to better understand the association of gastrointestinal events with patient-reported outcomes in postmenopausal women of this region. MUSIC OS-AP is a prospective, multinational, observational cohort study of postmenopausal women ≥ 50 years of age diagnosed with osteoporosis. The study was conducted in five Asia-Pacific countries: Australia, New Zealand, Taiwan, Korea, and India. MUSIC OS-AP has three components: a physician questionnaire, a retrospective chart review, and a prospective cohort study. The physician questionnaire investigated the role of gastrointestinal events in physicians' pharmacologic management of osteoporosis. The retrospective chart review, also completed by physicians, recorded rate of osteoporosis treatment and the types of osteoporosis medications prescribed to osteoporosis patients. The prospective cohort study investigated the associations between gastrointestinal events and patient-reported outcomes among patients taking oral medications for osteoporosis as well as reasons for non-treatment in patients who remained untreated. The prospective cohort study enrolled two groups of patients: untreated, and treated with oral osteoporosis medications. Untreated patients completed only the baseline surveys, providing information on gastrointestinal event rates, quality of life, health care resource use, and reasons for non-treatment. Treated patients, who were either new to osteoporosis medication or continuing an ongoing medication course, completed surveys at baseline and 3, 6, and 12 months post-baseline. The evaluations recorded patient characteristics, gastrointestinal events, health-related and osteoporosis-specific quality of life, health care resource use, medication adherence, and satisfaction with

    The aim of the study was to evaluate the number of circulating endothelial progenitor cells (circulating EPCs) in the blood of patients diagnosed with breast cancer and to make an attempt at finding associations with the number of circulating EPCs and selected clinic-pathological factors; TNM and histological grading, molecular subtype of breast cancer, hormonal status, the expression of Ki-67 and the size of tumour. The study involved 96 Caucasian ethnicity post-menopausal women. Sixty-six women aged 48 - 63 (mean age 55) with breast cancer diagnosis without distant metastases (M0). The median value of the tumour diameter was 1.51 cm. The control group consisted of 30 healthy, non-smoking, post-menopausal women, mean age 49, range 44 - 54 years of age. The exclusion criteria for all the participants were hypertension, hyperlipidaemia, and hyperglycaemia, acute and chronic infection. With regard to the fresh blood samples the number of circulating endothelial progenitors was determined using flow cytometry. The fluorescence of 100,000 cells was measured during the analysis. Circulating EPCs were identified with the immune-phenotype CD45 - , CD34 + , CD133 + , CD31 + . A significantly higher number of circulating EPCs in the study group, as compared to the controls (P = 0.0001) and a significantly higher number of circulating EPCs in women over 60 with breast cancer than in the younger women (P = 0.0029) were reported. A positive correlation was noted between circulating EPCs and age as well as between circulating EPCs and HER-2 (P = 0.0231, P = 0.0414, respectively), and a negative correlation between circulating EPCs and histological grading of breast cancer (P = 0.0272). The study has shown a higher number of circulating EPCs in breast cancer patients, which indicates stimulation of neovascularization. Additionally, since bone morrow-derived circulating EPCs are more intensively mobilised in older and overweight breast cancer patients, we can speculate that more

    Osteoporosis is one of the most common disorders in postmenopausal women, affecting the quality of life and increasing the risk for fractures in minor traumas. Changes in the bone microarchitecture causes static changes in the body and affects motility. In this study, we analyzed two groups of women, one with physiological menopause and one with surgically induced menopause. The diagnosis of osteoporosis was suspected based on the clinical symptoms and confirmed by assessing bone mineral density by the dual-energy X-ray absorptiometry (DEXA). Comparing some clinical and biological aspects there was noted that a much higher percentage of women with surgically induced menopause exhibited increases in body mass index, changes in serum lipids, cholesterol, triglycerides, blood glucose, serum calcium, magnesemia and osteocalcin. In contrast, no significant differences were observed in the histopathological aspects of bone tissue examined from these two groups. In all patients, there was identified a significant reduction in the number of osteocytes and osteoblasts, the expansion of haversian channels, reducing the number of trabecular bone in the cancellous bone with wide areola cavities often full of adipose tissue, non-homogenous demineralization of both the compact bone and the cancellous bone, atrophy and even absence of the endosteal, and the presence of multiple microfractures. Our study showed that early surgically induced menopause more intensely alters the lipid, carbohydrate and mineral metabolism, thus favoring the onset of osteoporosis.

    The objectives of this study were to estimate persistence with denosumab and put these results in context by conducting a review of persistence with oral bisphosphonates. Persistence with denosumab was found to be higher than with oral bisphosphonates. This study had two objectives: to analyse persistence in Swedish women initiating denosumab for treatment of postmenopausal osteoporosis (PMO) and to put these findings in context by conducting a literature review and meta-analysis of persistence data for oral bisphosphonates. The study used the Swedish Prescribed Drug Register and included women aged at least 50 years initiating denosumab between May 2010 and July 2012. One injection of denosumab was defined as 6-month persistence. Women were considered persistent for another 6 months if they filled their next prescription within 6 months + 56 days and survival analysis applied to the data. A literature search was conducted in PubMed to identify retrospective studies of persistence with oral bisphosphonates and pooled persistence estimates were calculated using a random-effects model. The study identified 2,315 women who were incident denosumab users. Mean age was 74 years and 61% had been previously treated for PMO. At 12 and 24 months, persistence with denosumab was 83% (95% CI, 81-84%) and 62% (95% CI, 60-65%), respectively. The literature search identified 40 articles for inclusion in the meta-analysis. At 12 and 24 months, persistence with oral bisphosphonates ranged from 10% to 78% and from 16% to 46%, with pooled estimates of 45% and 30%, respectively. These data from the Swedish Prescribed Drug Register and literature review suggest that persistence was higher with denosumab than with oral bisphosphonates.

    also observed in hormone replacement therapy in postmenopausal women who did not smoke. Peroral hormone replacement therapy does not induce favorable lipid changes in smokers. Higher triglycérides levels observed after one-year therapy in women with a longer smoking history indicate that transdermal replacement maybe more suitable in this group. Peroral oestrogen replacement has no anticoagulant or procoagulant activity in smokers during the early postmenopausal period.

    The human pinworm Enterobius vermicularis is normally found within the human gastrointestinal tract. Pregnant females migrate out of their host's anus at night to lay their eggs perianally.

    Cortical (neck of femur) and trabecular bone mass (L2-4) have been determined repeatedly with DPA using GD 153 (NOVO Lab 22 a) in 545 female and 112 male pts with no evidence of bone diseases. Measured 'normal', (age- and sex-related average) BMC values differed significantly from those of US people determined by same equipment, i.e., were in average about 30% lower, but matched well with corresponding results from Belgium. BMC-area was found the most suitable parameter both for cross-sectional and longitudinal studies, since BMC-area is independent from height and weight. But there is still need to reduce the overlap and improve accuracy and reproducibility for making decisions after shorter intervals. Assessment of the individual mineral loss and fracture risk by comparing to average values, however, remains problematic due to the wide range of 'normal' BMC and in women additionally due to the variable onset of menopause. For estimations of the individual fracture risk of elderly pts BMC should not be normalized on age, because at the age of 65 half of the women had 'pathologic' values, i.e. were below the so called 'osteoporosis threshold'. Comparison of the individually measured postmenopausal BMC to average values of premenopausal women and to BMC values normalized to their menopausal age may be helpful approaches for overcoming these difficulties. Because of the lack of earlier individual data in most cases repeated BMC measurements are still required for assessment of demineralization speed. Preliminary results of estrogen replacement therapy with low doses of natural conjugated estrogen show good prevention of bone loss in healthy but not in ovarectomized women. (orig./MG)

    Background: Sugar-sweetened beverages (SSBs) have been associated with an increased risk of diabetes mellitus (DM), whereas the association with artificially sweetened beverages (ASBs) is unclear. Objective: We aimed to evaluate the associations of ASB and SSB consumption with the risk of developing DM and the potential benefit of replacing SSBs with ASBs or water. Design: The national Women's Health Initiative recruited a large prospective cohort of postmenopausal women between 1993 and 1998. ASB, SSB, and water consumption was measured by lifestyle questionnaires, and DM was self-reported. Results: Of 64,850 women, 4675 developed diabetes over an average of 8.4 y of follow-up. ASBs and SSBs were both associated with an increased risk of DM with an HR of 1.21 (95% CI: 1.08, 1.36) comparing ASB consumption of ≥2 serving/d to never or <3 serving/mo, and an HR of 1.43 (95% CI: 1.17, 1.75) comparing SSB consumption of ≥2 serving/d to <1 serving/wk (1 serving = one 12-ounce can or 355 mL). Subgroup analysis found an increased risk of DM associated with ASBs only in the obese group. Modeling the substitution of SSBs with an equal amount of ASBs did not significantly reduce the risk of developing DM. However, statistically substituting 1 serving of ASBs with water was associated with a significant risk reduction of 5% (HR: 0.95; 95% CI: 0.91, 0.99), whereas substituting 1 serving of SSBs with water was associated with a risk reduction of 10% (HR: 0.90; 95% CI: 0.85, 0.95). Conclusions: ASBs were associated with a 21% increased risk of developing DM, approximately half the magnitude of SSBs (associated with a 43% increased risk). Replacing ASBs and SSBs with water could potentially reduce the risk. However, caution should be taken in interpreting these results as causal because both residual confounding and reverse causation could explain these results. © 2017 American Society for Nutrition.

    Full Text Available Abstract Background International treatment guidelines recommend administration of adjuvant chemotherapy in early breast cancer based on clinical, prognostic and predictive parameters. Methods An observational study (NEMESI was conducted in 63 Italian oncology centres in patients with early breast cancer. Age, performance status, concomitant disease, menopausal status, histology, tumor dimension (pT, axillary lymph node status (pN, grading (G, estrogen and progesterone receptor (ER and PgR, proliferative index (ki67 or MIB-1, human epidermal growth factor receptor 2 (HER2 and type of adjuvant treatment were recorded. The primary objective of the study was to define parameters influencing the decision to prescribe adjuvant chemotherapy and the type of chemotherapy. Results Data for 1894 patients were available. 69.0% postmenopausal, 67.0% pT1, 22.3% pTmic/pT1a/pT1b, 61.0% pN0, 48.7% luminal A, 18.1% luminal B, 16.1% HER2 positive, 8.7% triple negative, 8.4% unknown. 57.8% received adjuvant chemotherapy: 38.1% of luminal A, 67.3% luminal B, 88.2% HER2-positive, 97.6% triple negative. Regimens administered: 9.1% CMF-like, 48.8% anthracyclines, 38.4% anthracyclines plus taxanes, 3.7% taxanes alone. Increasing pT/pN and, marginally, HER2-positive were associated with the prescription of anthracyclines plus taxanes. Suboptimal schedules (CMF-like or AC/EC or FEC-75 were prescribed in 37.3% receiving chemotherapy, even in HER2-positive and triple negative disease (36.5% and 34.0%, respectively. Conclusions This study showed an overprescription of adjuvant chemotherapy for early breast cancer, particularly referred to luminal A. pT, pN and, marginally, HER2 were the principal determinants for the choice of chemotherapy type. Suboptimal chemotherapy regimens were adopted in at least one third of HER2-positve and triple negative.

    One of the most common complaints among postmenopausal women is a change in sexual drive. The aim of this study was to assess the current state of sexual health in Spanish postmenopausal women who present at outpatient gynecology clinics. In this multicenter, observational, cross-sectional, questionnaire-based study, a survey was conducted that included 3026 Spanish postmenopausal women in a routine clinical setting in outpatient gynecology clinics at public and private institutions throughout Spain. We used the Women's Sexual Function questionnaire, which has been validated in Spain. In the multivariate analysis, we found that the best indicators of sexual health in postmenopausal women were a higher education (p education and information about menopause and the complaints associated with this period in a woman's life.

    Neutron star Interior Composition ExploreR (NICER) is an X-ray telescope attached to the International Space Station (ISS). Launched in June 2017, it is designed to precisely measure the masses and radii of neutron stars (NS) and probe NS equations of state. But its precision timing capabilities and large effective area uniquely position NICER for the study of magnetars. The NICER Magnetar & Magnetosphere (M&M) science working group focuses on studying highly-magnetized neutron stars, a diverse program that includes magnetars, high-B pulsars, rotation powered pulsars, and isolated neutron stars. Our ongoing campaign has already observed targets such as 4U 0142+61, a magnetar in outburst with coincident NuSTAR and Swift observations, the radio rotation powered Vela pulsar PSR B0833-45, and a transient magnetar XTE J1810-197. I will discuss the goals of the M&M program, spectral and temporal results from the observed targets, and an overview of upcoming observations.

    The recently detected TRAPPIST-1 planetary system, with its seven planets transiting a nearby ultracool dwarf star, offers the first opportunity to perform comparative exoplanetology of temperate Earth-sized worlds. To further advance our understanding of these planets' compositions, energy budgets, and dynamics, we are carrying out an intensive photometric monitoring campaign of their transits with the Spitzer Space Telescope. In this context, we present 60 new transits of the TRAPPIST-1 planets observed with Spitzer/Infrared Array Camera (IRAC) in 2017 February and March. We combine these observations with previously published Spitzer transit photometry and perform a global analysis of the resulting extensive data set. This analysis refines the transit parameters and provides revised values for the planets' physical parameters, notably their radii, using updated properties for the star. As part of our study, we also measure precise transit timings that will be used in a companion paper to refine the planets' masses and compositions using the transit timing variations method. TRAPPIST-1 shows a very low level of low-frequency variability in the IRAC 4.5-μm band, with a photometric RMS of only 0.11 per cent at a 123-s cadence. We do not detect any evidence of a (quasi-)periodic signal related to stellar rotation. We also analyse the transit light curves individually, to search for possible variations in the transit parameters of each planet due to stellar variability, and find that the Spitzer transits of the planets are mostly immune to the effects of stellar variations. These results are encouraging for forthcoming transmission spectroscopy observations of the TRAPPIST-1 planets with the James Webb Space Telescope.

    Full Text Available BACKGROUND: Progesterone is effective treatment for hot flushes/night sweats. The cardiovascular effects of progesterone therapy are unknown but evidence suggests that premenopausal normal estradiol with also normal progesterone levels may provide later cardiovascular protection. We compared the effects of progesterone to placebo on endothelial function, weight, blood pressure, metabolism, lipids, inflammation and coagulation. METHODS AND RESULTS: We conducted a randomized, double-blind, 3-month placebo-controlled trial of progesterone (300 mg daily among 133 healthy postmenopausal women in Vancouver, Canada from 2003-2009. Endothelial function by venous occlusion plethysmography was a planned primary outcome. Enrolled women were 1-11 y since last menstruation, not using hormones (for >6 months, non-smoking, without diabetes, hypertension, heart disease or their medications. Randomized (1∶1 women (55 ± 4 years, body mass index 25 ± 3 initially had normal blood pressure, fasting lipid, glucose and electrocardiogram results. Endothelial function (% forearm blood flow above saline was not changed with progesterone (487 ± 189%, n = 18 compared with placebo (408 ± 278%, n = 16 (95% CI diff [-74 to 232], P = 0.30. Progesterone (n = 65 and placebo (n = 47 groups had similar changes in systolic and diastolic blood pressure, resting heart rate, weight, body mass index, waist circumference, total cholesterol, low-density lipoprotein cholesterol and triglyceride levels. High-density lipoprotein was lower (-0.14 mmol/L, P = 0.001 on progesterone compared with placebo. Fasting glucose, hs-C-reactive protein, albumin and D-dimer changes were all comparable to placebo. Framingham General Cardiovascular Risk Profile scores were initially low and remained low with progesterone therapy and not statistically different from placebo. CONCLUSIONS: Results indicate that progesterone has short-term cardiovascular safety. Endothelial

    Central (hypogonadotropic) hypogonadism in women could be a cause of persistent amenorrhea and hypoestrogenemia as observed in postmenopause. This study aimed to compare the clinical, hormonal and biochemical features in women with non-physiological (central hypogonadism) and physiological (postmenopause) hypoestrogenemia. A total of 161 young women, median age 24.9 years (interquartile range (IQR) 21.2; 30.5) with central hypogonadism (with isolated hypogonadotropic hypogonadism, n = 76, and with hypopituitarism, n = 85), 53 healthy young women, median age 23.9 years (IQR 23.1; 28.0) and 50 healthy postmenopausal women, median age 56.0 years (IQR 53.1; 58.5), were examined. Psychoemotional, neurovegetative and urogenital symptoms, sex steroid levels, parameters of lipid and mineral metabolism were evaluated. In young women with central hypogonadism, the frequencies of psychoemotional, neurovegetative and urogenital complaints differed significantly from those in healthy young women and were similar to those in postmenopausal women. Concentrations of estradiol, testosterone, dehydroepiandrosterone sulfate, parameters of lipid and mineral metabolism as well as quality of life in women with central hypogonadism were not typical of healthy young women but were similar to those of postmenopausal women of middle/old age. Despite the young age of women with central hypogonadism, clinical, hormonal and biochemical abnormalities were similar in many aspects to those in postmenopausal women at middle/old age. These revealed features could be considered as signs of premature aging in young amenorrheic women with low gonadotropin levels.

    Scientific studies show that many factors related to lifestyles affect the reduction of bone mineral density and osteoporosis in postmenopausal women. The goal of this study was to determine whether smoking, drinking coffee and alcohol in menopausal women contribute to the reduction of bone mass and osteoporosis, as well as the impact of physical activity on bone mass. The study was carried out as case study and matched controls. The group of cases consisted of 100 females in postmenopausal age, in which by the DEXA method was newly diagnosed osteoporosis at the Clinic of Endocrinology, Diabetes and Metabolic Diseases, University Medical Center of RS during 2015-2016, while the control group consisted of 100 females in a postmenopausal age without diagnosed osteoporosis. The groups were matched by age (±2 years). In order to collect demographic data and information on risk factors for osteoporosis and lifestyle of patients was used the questionnaire Bone Mineral Density Questionnaire- Female of the Irish Association for osteoporosis. Testing the significance of differences in terms of smoking showed that the studied groups are statistically significantly different in terms of smoking (χ 2 =24.025, p=0.000). In terms of consumption of coffee, a statistically significant difference was found between the group of cases and control group (χ 2 =0.615, p=0.735). When observing the obtained information about the consumption of alcohol, we find that this preventable risk factor in the present study did not show as significant for osteoporosis in postmenopausal women (χ 2 =4.35, p=0.114). Statistical analysis shows that there are significant differences between the group of cases and control group in terms of physical activity (χ 2 =7.30, p=0.026). Analysis of the data of our study by univariate logistic regressions showed that smoking (p=0.000) was statistically significantly associated with osteoporosis, while physical activity is a protective factor for bone mass (p

    Menopause is defined as the permanent cessation of menses. Although previous studies demonstrated a slight production of androgens and estrogens by postmenopausal ovaries, the impact of hormone production on lipid metabolism is still uncertain. The aim of this study was to evaluate whether the postmenopausal ovary is hormonally active and whether hormone status contributes to lipid metabolism. This was a prospective study of 87 women who were treated for gynecological diseases (29% had cervical cancer, 49% had endometrial cancer, 7% had fibroid tumors, and 15% had cervical intraepithelial neoplasia). They were categorized as early postmenopausal (n = 40; mean [SD], 56.8 [3.8] y) or late postmenopausal (n = 47; mean [SD], 66.6 [5.7] y) women. Serum specimens were collected from the peripheral and ovarian veins of participants undergoing bilateral oophorectomy. Sex steroid hormone levels and lipid profiles were determined. Statistically significant differences in estradiol (E2) and testosterone were seen between the ovarian samples and the peripheral samples in all groups. E2 and estrone obtained from ovarian venous samples gradually decreased with age in postmenopausal women. There was a significant correlation between ovarian E2 and high-density lipoprotein cholesterol levels and the low-density lipoprotein-to-high-density lipoprotein ratio. However, there was no correlation between peripheral E2 levels and any of the lipid parameters examined. Although this study investigates women with gynecological diseases, the postmenopausal ovary is hormonally active, and the E2 produced by postmenopausal ovaries may therefore contribute to the maintenance of lipid metabolism.

    Full Text Available Introduction: There is very little published literature about experience with osteoporosis treatment from our country. Materials and Methods: It is a retrospective analysis of first 50 patients enrolled in our clinic for osteoporosis. Postmenopausal women with T score of less than -2.5 or history suggestive fragility fracture with supportive bone mineral density (BMD were included. Patients having hypercalcemia, abnormal renal function, myeloma and on long-term steroids were also excluded. Results: Nearly 34% subjects were below the age of 60 years, 47% of subjects were between 60 and 70 years, whereas 18% were above 70 years. Nearly 6% had family history of osteoporosis s or history of osteoporotic fractures. Nearly 20% subjects had fracture prior to starting of any treatment. A total of 86% (40/46 had evidence of Vitamin D (VD deficiency. Nearly 80% of patients were treated with bisphosphonates, 12% were treated with injectable bisphosphonates, and 8% were treated with teriperatide. Nearly 16% patients had duration of more than 5 years of experience with bisphosphonates. Follow up BMD was available in 25 subjects. BMD had improved significantly in 68% of subjects. In 24% the BMD was stable (the change was less than least significant change (LSC. In 8% BMD had shown a significant decline while being on treatment. Conclusion: Postmenopausal osteoporosis occurs in relatively younger women in our country. Majority of them are VD deficient. Oral bisphosphonates is the most common used drug; it is fairly well tolerated and effective.

  10. Clinical Practice. Postmenopausal Osteoporosis.

    Black, Dennis M; Rosen, Clifford J

    2016-01-21

    Key Clinical Points Postmenopausal Osteoporosis Fractures and osteoporosis are common, particularly among older women, and hip fractures can be devastating. Treatment is generally recommended in postmenopausal women who have a bone mineral density T score of -2.5 or less, a history of spine or hip fracture, or a Fracture Risk Assessment Tool (FRAX) score indicating increased fracture risk. Bisphosphonates (generic) and denosumab reduce the risk of hip, nonvertebral, and vertebral fractures; bisphosphonates are commonly used as first-line treatment in women who do not have contraindications. Teriparatide reduces the risk of nonvertebral and vertebral fractures. Osteonecrosis of the jaw and atypical femur fractures have been reported with treatment but are rare. The benefit-to-risk ratio for osteoporosis treatment is strongly positive for most women with osteoporosis. Because benefits are retained after discontinuation of alendronate or zoledronic acid, drug holidays after 5 years of alendronate therapy or 3 years of zoledronic acid therapy may be considered for patients at lower risk for fracture.

    Full Text Available Background The most common symptom in early menopausal women is depression. Depression is a type of chronic disease that impacts on postmenopausal women’s life. Social support plays a protective role for women and enables them to solve their life problems and thus, feel less depressed. Objectives We assessed depression as a chronic disease and evaluated the association between perceived social support and depression in postmenopausal women. Patients and Methods This correlation-analytic study was conducted on 321 postmenopausal women using 2-stage cluster sampling in Ahvaz in 2014. Data collecting instruments were comprised of a demographic questionnaire, a depression scale (Beck Depression Inventory-II, and a social support questionnaire (PRQ 85-Part 2. Data analysis was done using SPSS, version 20. The Spearman correlation coefficient was used to evaluate the relationship between perceived social support and depression, and the χ2 test was employed to assess the relationship between perceived social support and demographic characteristics. Results The Spearman correlation test revealed a significant reverse relationship between perceived social support and depression (r = -0.468; P = 0.001. There were significant relationships between perceived social support and some personal variables such as marital status, education level, and job status (P 0.05. Conclusions We found a reverse relationship between perceived social support and depression in postmenopausal women. Raising awareness in society apropos the relationship between social support and depression in postmenopausal women can enhance their quality of life.

    Aromatase inhibitors provide superior disease control when compared with tamoxifen as adjuvant therapy for postmenopausal women with endocrine-responsive early breast cancer. To present the design, history, and analytic challenges of the Breast International Group (BIG) 1-98 trial: an international, multicenter, randomized, double-blind, phase-III study comparing the aromatase inhibitor letrozole with tamoxifen in this clinical setting. From 1998-2003, BIG 1-98 enrolled 8028 women to receive monotherapy with either tamoxifen or letrozole for 5 years, or sequential therapy of 2 years of one agent followed by 3 years of the other. Randomization to one of four treatment groups permitted two complementary analyses to be conducted several years apart. The first, reported in 2005, provided a head-to-head comparison of letrozole versus tamoxifen. Statistical power was increased by an enriched design, which included patients who were assigned sequential treatments until the time of the treatment switch. The second, reported in late 2008, used a conditional landmark approach to test the hypothesis that switching endocrine agents at approximately 2 years from randomization for patients who are disease-free is superior to continuing with the original agent. The 2005 analysis showed the superiority of letrozole compared with tamoxifen. The patients who were assigned tamoxifen alone were unblinded and offered the opportunity to switch to letrozole. Results from other trials increased the clinical relevance about whether or not to start treatment with letrozole or tamoxifen, and analysis plans were expanded to evaluate sequential versus single-agent strategies from randomization. Due to the unblinding of patients assigned tamoxifen alone, analysis of updated data will require ascertainment of the influence of selective crossover from tamoxifen to letrozole. BIG 1-98 is an example of an enriched design, involving complementary analyses addressing different questions several years

    Full Text Available Introduction: Health status and health-related quality of life of postmenopausal women are issues, which nowadays pose a serious challenge to many domains of science. Climacteric symptoms which occur at this stage of life, lower its quality and make a negative contribution to self-reported health status, are mostly observed in a particular group of women. Evaluation of health behaviors performed using a standardized questionnaire, the Health Behavior Inventory (HBI, may help establish a comprehensive diagnosis of women’s health, and thus select effective interventions. A systemic approach to menopause assumes that full fitness of women and good quality of their lives can be maintained not only by means of pharmacotherapy but also other forms of action, especially health education oriented towards changes in the lifestyle and promotion of healthy behaviors. The aim of this study is to perform a HBI-based assessment of women’s health behaviors in such categories as healthy eating habits (HEH, preventive behaviors (PB, positive mental attitudes (PMA, and health practices (HP. Material and methods: The study involved 151 healthy postmenopausal women. A research tool was a standardized questionnaire, the Health Behavior Inventory (HBI. Results: The surveyed women obtained 70% of the maximum score on average, which suggests a medium level of health behaviors in this group. The levels of health behaviors in the categories of positive mental attitudes and health practices significantly differed between older women and their younger counterparts (higher levels were observed among older respondents. There were also significant differences in the levels of healthy behaviors between women with secondary and higher education (those better educated declared healthy behaviors more often. There was no correlation between the level of health behaviors and the BMI of the surveyed women. Conclusions : Older women attached greater

  17. Differential genetic basis for pre-menopausal and post-menopausal salt-sensitive hypertension.

    Directory of Open Access Journals (Sweden)

    Victoria L M Herrera

    Full Text Available Essential hypertension affects 75% of post-menopausal women in the United States causing greater cardiovascular complications compared with age-matched men and pre-menopausal women. Hormone replacement and current anti-hypertensive therapies do not correct this post-menopausal increased risk suggesting a distinct pathogenic framework. We investigated the hypothesis that distinct genetic determinants might underlie susceptibility to salt sensitive hypertension in pre-menopausal and post-menopausal states. To determine whether distinct genetic loci contribute to post-menopausal salt-sensitive hypertension, we performed a genome-wide scan for quantitative trait loci (QTLs affecting blood pressure (BP in 16-month old post-menopausal F2 (Dahl S×R-intercross female rats characterized for blood pressure by radiotelemetry. Given identical environments and high salt challenge, post-menopausal BP levels were significantly higher than observed in pre-menopausal (post-menopausal versus pre-menopausal SBP, P<0.0001 and ovariectomized (post-menopausal versus ovariectomized SBP, P<0.001 F2-intercross female rats. We detected four significant to highly significant BP-QTLs (BP-pm1 on chromosome 13, LOD 3.78; BP-pm2 on chromosome 11, LOD 2.76; BP-pm3 on chromosome 2, LOD 2.61; BP-pm4 on chromosome 4, LOD 2.50 and two suggestive BP-QTLs (BP-pm5 on chromosome 15, LOD 2.37; BP-f1 on chromosome 5, LOD 1.65, four of which (BP-pm2, BP-pm3, BP-pm4, BP-pm5 were unique to this post-menopausal cohort. These data demonstrate distinct polygenic susceptibility underlying post-menopausal salt-sensitive hypertension providing a pathway towards the identification of mechanism-based therapy for post-menopausal hypertension and ensuing target-organ complications.

    Postmenopausal women on aromatase inhibitors (AI) are at risk of aromatase inhibitor-associated bone loss (AIBL) and fractures. In 2005 Osteoporosis Australia proposed an algorithm for bisphosphonate intervention. Three hundred and three postmenopausal women with early breast cancer (EBC) were enrolled (osteoporotic, n=25; osteopaenic, n=146; normal bone mineral density (BMD), n=126). Weekly alendronate (70 mg) treatment efficacy as triggered by the algorithm in preventing bone loss was evaluated. All patients received anastrozole (1 mg daily), calcium and vitamin D. All osteoporotic patients received alendronate at baseline. Eleven out of the 146 (7.5%) osteopaenic patients commenced alendronate within 18 months of participation and eleven commenced after. One hundred and twenty four out of the 146 (84.9%) osteopaenic patients and all 126 with normal baseline BMD did not trigger the algorithm. At three years, lumbar spine mean BMD increased (15.6%, p<0.01) in the osteoporotic group. BMD in the osteopaenic group with early intervention significantly increased at three years (6.3%, p=0.02). No significant change was seen in the late intervention group. No change was observed in those with osteopaenia without alendronate. There was a significant drop in lumbar spine (-5.4%) and hip (-4.5%) mean BMD, in the normal BMD group, none of whom received alendronate. Fracture data will be presented. In postmenopausal women with endocrine-responsive EBC, BMD improved over time when a bisphosphonate is administered with anastrozole in osteoporotic patients using an osteoporosis schedule. Subjects with normal baseline BMD experienced the greatest BMD loss, although none became osteoporotic.

    Full Text Available Postmenopausal bleeding (PMB is a discharge that occurs following the firm diagnosis of menopause, which is at least six months from the end of women’s menstrual cycle but not to be confused with infrequent or irregular periods occurring around the time of menopause. It is a common problem representing 5% of all gynecology outpatient attendances which are to eliminate endometrial cancer as the cause of bleed and PMB should be reported urgently to the gynecologist. Uterine bleeding in postmenopausal women is highly indicative clinically of malignancy originating from cervix or endometrium and Human papilloma virus (HPV is one of the causative agent for carcinoma cervix. Incidence of carcinoma cervix increases with the age in mature women, however, incidence of human papillomavirus (HPV infection reduces as menopause sets in. The presence of the virus could be used as an early indication of disease potential. Because the Pap test can only detect clinical evidence of cervical disease, molecular-based diagnostic tools are being used more frequently to detect the virus before abnormal cell growth can be observed. This study was aimed to determine the status of cervical cancer and HPV 16 DNA positivity in relation to postmenopausal bleeding.

    Whereas the beneficial effects of intermittent treatment with parathyroid hormone (PTH) (intact PTH 1-84 or fragment PTH 1-34, teriparatide) on vertebral strength is well documented, treatment may not be equally effective in the peripheral skeleton. We used high resolution peripheral quantitative...... computed tomography (HR-pQCT) to detail effects on compartmental geometry, density and microarchicture as well as finite element (FE) estimated integral strength at the distal radius and tibia in postmenopausal osteoporotic women treated with PTH 1-34 (20 µg sc. daily, n=18) or PTH 1-84 (100 µg sc. daily......, n=20) for 18 month in an open label, non-randomized study.

  2. Role of bisphosphonates in postmenopausal women with breast cancer.

    2014-04-01

    Data suggest that bisphosphonates protect bone health and may have anticancer activity in postmenopausal women during adjuvant breast cancer therapy. However, key questions remain surrounding the role of adjuvant bisphosphonates in breast cancer, including patient populations deriving benefit, timing/scheduling of therapy, and specific clinical benefits. PubMed, Embase, and San Antonio Breast Cancer Symposium databases provide study results that address these issues in postmenopausal women. Review of these data would aid physicians in providing optimal management of breast cancer in postmenopausal women. For example, recent data reinforce use of intravenous bisphosphonates concurrently with adjuvant endocrine therapy to ameliorate bone loss in recently postmenopausal or osteopenic postmenopausal women with early breast cancer. In contrast, clinical data for oral bisphosphonates have not provided support for using anti-osteoporosis doses in this setting, and the optimal dose is unclear. Additionally, current clinical data show improvements in disease outcomes with bisphosphonates in many studies, although not in all patient subsets. Strong support for the potential adjuvant anticancer benefits from bisphosphonates has been demonstrated in women with established menopause (i.e., very low circulating estrogen levels). Initiating bisphosphonates early and concomitantly with adjuvant therapy generally provided the greatest benefits. However, questions remain such as schedule of treatment and relative potency among the intravenous bisphosphonates and elucidation of the role of oral bisphosphonates, as well as ongoing studies that might provide clarification. This review addresses these controversies in the context of translational research, which may provide the rationale for ongoing studies and evolving treatment paradigms in this area.

    Postmenopausal osteoporosis is a frequent cause of morbidity and can negatively impact life expectancy; iodine is an essential element for bone mineralization, and iodine deficiency is frequently observed. The aim of the present study was to understand the connection between postmenopausal osteoporosis and the level of iodine in the body. A total of 132 participants were divided into three groups: group 1 consisted of healthy postmenopausal women (n = 34), group 2 comprised osteopenic women (n = 38), and group 3 included women with postmenopausal osteoporosis (n = 60). The three groups were compared according to demographic, clinical, and laboratory findings. The urinary iodine levels were recorded as 216.1 ± 125.2 in the control group, 154.6 ± 76.6 in the osteopenic group, and 137.5 ± 64.9 in the postmenopausal osteoporosis group (P < 0.001). These differences were maintained after adjustment for body mass index (P < 0.001). The urinary iodine level accurately correlated with the total T-score for the lumbar spine (r = 0.236, P = 0.008). Multiple regression analysis showed that corrected for body mass index, alkaline phosphatase isoenzyme, and urinary deoxypyridinoline, the urinary iodine level was significantly associated with total T-score (beta coefficient = 0.270, P = 0.006). The urinary iodine level was significantly lower in women with postmenopausal osteoporosis, and iodine replacement may be important in preventing osteoporosis in areas where iodine deficiency is endemic.

    Diminished bone strength increases the frequency of osteoporosis and fragility fractures. Weight and gonadal status are important determinants of bone mass in women. This study tried to find out the bone strength and its determinants in peri- and postmenopausal age groups of women. Methods: One hundred and twenty females with age range 25 - 66 years were included in the study. According to their age and menstrual status they were divided into premenopausal (30) peri menopausal (50) and postmenopausal (40). Body Mass Index (MBI) and bone related blood parameter, serum calcium, magnesium, inorganic phosphorus, alkaline phosphatase and estradiol were estimated. Bone mineral density was taken by peripheral densitometer. Results: Blood chemical parameters were not significantly different in these groups. The p-value of serum estradiol was highly significant in peri- and postmenopausal groups. BMI was significantly high in postmenopausal as compared to pre and perimenopausal groups. Conclusion: Early menopause, low levels of oestrogen and BMI values can all affect the health of bones in elderly women. (author)

    The purpose of this study was to compare periodontal status of postmenopausal women with mild to moderate osteoporosis who use risedronate therapy with those who do not. In this cross-sectional study, a total of 60 age-matched postmenopausal women with mild to moderate osteoporosis diagnosed by a bone density scan T score below -2.5 at either spine or hip were divided into two groups. Women in the experimental group had used systemic risedronate once weekly (35 mg) for at least 3 months. Women in the control group had never used bisphosphonate therapy. The periodontal status of each subject was evaluated through a clinical periodontal examination including evaluation of periodontal probing depth, gingival recession, gingival index, plaque score, attachment loss, and alveolar bone level. The significance in differences between the two groups was assessed using two-tailed paired t tests. Significant differences (P periodontal probing depth (2.6 vs 2.9 mm), gingival index (0.37 vs 0.71), plaque score (56.2 vs 77.0), attachment loss (2.8 vs 3.2 mm), and alveolar bone level (3.1 and 4.0), respectively. Gingival recession parameters did not differ significantly. Five of six periodontal parameters evaluated show that postmenopausal women with mild to moderate osteoporosis using risedronate therapy have healthier periodontal status than those who do not use bisphosphonates. Women using risedronate therapy show significantly less plaque accumulation, less gingival inflammation, lower probing depths, less periodontal attachment loss, and greater alveolar bone levels. These observations suggest that risedronate therapy may play a beneficial role in periodontal status.

    To explore the clinical efficacy of electroacupuncture intervention on severe acute pancreatitis (SAP) at early stage complicated with intestinal paralysis. Sixty-eight cases of SAP were randomly divided into observation group (48 cases) and control group (20 cases). In observation group, according to the course of sickness, the early-stage subgroup (30 cases, hospitalized in 3 d) and late-stage subgroup (18 cases, hospitalized in 3-7 d) were subdivided. In control group, the conventional treatment was applied. In observation group, based on the same treatment as control group, electroacupuncture was supplemented at Zhongwan (CV 12), Zusanli (ST 36), Neiguan (PC 6), Hegu (LI 4), etc. Acute physiology and chronic health evaluation (APACHE) II scores, the recovery time of intestinal paralysis and laboratory indices, complications, operation transfer rate, death rate and the admission time were compared among groups after treatment. The total effective rate was 83.3% (25/30) in early-stage subgroup, which was superior to 72.2% (13/18) in late-stage subgroup and 65.0% (13/20) in control group (P complications, operation transfer rate, death rate and admission time were all lower remarkably than those in late-stage subgroup and control group (P 0.05). The clinical efficacy of electroacupuncture intervention on SAP complicated with intestinal paralysis is superior remarkably to that of conventional treatment, and the efficacy of electroacupuncture intervention at early stage is better than that at late stage.

  13. Early Observations of the Type Ia Supernova iPTF 16abc

    2018-01-01

    Early observations of Type Ia supernovae (SNe) provide a unique probe of their progenitor systems and explosion physics. Here, we report the intermediate Palomar Transient Factory (iPTF) discovery of an extraordinarily young SN Ia, iPTF 16abc. By fitting a power law to our early light curve, we infer that first light for the SN only occurred 0.15 +0.15-0.07 d before our first detection. In the ~24 hr after discovery, iPTF 16abc rose by ~2 mag, following a near-linear rise in flux for ~3 d. Strong C II absorption is detected in the early spectra of iPTF 16abc, before disappearing after ~7 d. Unlike the extensively-observed Type Ia SN 2011fe, the (B-V)_0 colors of iPTF 16abc are blue and nearly constant in the days after explosion. We show that our early observations of iPTF 16abc cannot be explained by either SN shock breakout and the associated, subsequent cooling, or the SN ejecta colliding with a stellar companion. Instead, we argue that the early characteristics of iPTF 16abc, including: (i) the rapid, near-linear rise, (ii) the non-evolving blue colors, and (iii) the strong absorption from ionized carbon, are the result of either vigorous mixing of radioactive-Ni in the SN ejecta, or ejecta interaction with diffuse material, or a combination of the two. In the next few years, dozens of very young normal SNe Ia will be discovered, and observations similar to those presented here will constrain the white dwarf explosion mechanism.

    The U.S. Geological Survey (USGS) has a long history of supporting the use of Earth observation data for food security monitoring through its role as an implementing partner of the Famine Early Warning Systems Network (FEWS NET) program. The use of remote sensing and crop modeling to address food security threats in the form of drought, floods, pests, and changing climatic regimes has been a core activity in monitoring FEWS NET countries. In recent years, it has become a requirement that FEWS NET apply monitoring and modeling frameworks at global scales to assess emerging crises in regions that FEWS NET does not traditionally monitor. USGS FEWS NET, in collaboration with the University of California, Santa Barbara, has developed a number of new global applications of satellite observations, derived products, and efficient tools for visualization and analyses to address these requirements. (1) A 35-year quasi-global (+/- 50 degrees latitude) time series of gridded rainfall estimates, the Climate Hazards Infrared Precipitation with Stations (CHIRPS) dataset, based on infrared satellite imagery and station observations. Data are available as 5-day (pentadal) accumulations at 0.05 degree spatial resolution. (2) Global actual evapotranspiration data based on application of the Simplified Surface Energy Balance (SSEB) model using 10-day MODIS Land Surface Temperature composites at 1-km resolution. (3) Production of global expedited MODIS (eMODIS) 10-day NDVI composites updated every 5 days. (4) Development of an updated Early Warning eXplorer (EWX) tool for data visualization, analysis, and sharing. (5) Creation of stand-alone tools for enhancement of gridded rainfall data and trend analyses. (6) Establishment of an agro-climatology analysis tool and knowledge base for more than 90 countries of interest to FEWS NET. In addition to these new products and tools, FEWS NET has partnered with the GEOGLAM community to develop a Crop Monitor for Early Warning (CM4EW) which

    Full Text Available Background/Aim. Osteoporosis mainly affects women in the early years following menopause. The aim of this study was to determine the level of knowledge about osteoporosis and osteoporosis related risk factors in postmenopausal women in Serbia. Methods. The study included postmenopausal women regardless if suffering from osteoporosis or not. Assessment of knowledge was carried out by using the Osteoporosis Knowledge Assessment Tool - Shorter Version (OKAT-S questionnaire that was validated for Serbian population. Answers to the 9 questions were coded as 1 -true, or 0 - false or “do not know”. Also, the following risk factors data for osteoporosis were collected: age, the onset and duration of menopause, body mass index (BMI, data on fractures, the incidence of falls, smoking, lifestyle (active, sedentary, regular sunbathing, calcium and vitamin D supplementation, intake of milk and dairy products. Results. A total of 132 postmenopausal women responded to the questionnaire with the response rate of 90.41%. Their knowledge varied from 27.94% to 74.26% of the correct answers, with the average OKAT-S score of 4.5 (SD = 2.55, which was 50% of the maximum possible score. Only 2 participants (1.47% filled the all OKAT-S items correctly, while 11 (8.09% of them did not have the proper answer to any question. A reduced bone density (T-score below -1 was registered in 40.91% of the women, previous fractures in 49 (34.51%, and more or less 3 falls registered in 9.59% or 4.79%, respectively. Conclusion. The Serbian version of the questionnaire OKAT-S revealed generally poor knowledge on osteoporosis among postmenopausal women in Serbia. Developing effective interventions and public health programms could be helpful in general education towards understanding osteoporosis and risk factors. Promotion of preventive measures and healthy behaviour may prevent or at least slow down the accelerated bone loss in postmenopausal women.

    Delirium or acute confusion is a temporary mental disorder which occurs frequently among hospitalized elderly patients. Patients who undergo cardiac surgery have an increased risk of developing delirium. Prevention or early recognition of delirium is essential. The Delirium Observation Screening (DOS) scale was developed to facilitate early recognition of delirium by nurses' observations during routine clinical care. The aim of this study was to validate the DOS scale in accordance with the diagnosis of the psychiatrist, using the DSM-IV criteria as the gold standard. In this observational study, the DOS scale was used to assess whether 112 patients who underwent elective cardiac surgery had developed a postoperative delirium. The psychiatrist was consulted to confirm or refute the diagnosis delirium. Wilcoxon's Rank Sum Test was utilized to compare patients with and without delirium on duration of hospital stay. A Receiver Operating Characteristic Curve of the DOS scale was constructed with accompanying Area Under the Curve (AUC). Based on the diagnosis of the psychiatrist, the incidence of delirium following cardiac surgery was 21.4% and the mean duration of delirium was two and a half days. The time to discharge was 11 days longer in patients with delirium. In 27 of the 112 patients a DOS score of >or=3 was found, that indicates delirium. The sensitivity and specificity of the DOS scale was 100% and 96.6% respectively. The AUC was 0.98. The DOS scale is a very good instrument to facilitate early recognition of delirium by nurses' observation of patients who undergo cardiac surgery. Early recognition will expedite good postoperative management such as implementation of appropriate interventions, and may decrease negative consequences caused by postoperative delirium.

  19. Freud's views on early female sexuality in the light of direct child observation.

    1976-01-01

    Freud's writings on early female sexuality are reviewed in order to demonstrate which of his central assumptions are supported and which have been corrected by the direct observation of young children. The study of the emergence of core gender identity in little girls is a key to the modification of Freud's statements on the onset of and crucial factors in the development of femininity. Cognitive functions, learning experiences, and language are believed to be more important than Freud stressed, and penis envy and feelings of inferiority are relegated to a less universal and less necessary place in the onset of femininity. The role of the father is given different emphasis. Direct observation clarifies many aspects of masturbation or early genital self-stimulation in the young female: its onset; its feminine rather than masculine character; its early vicissitudes; its importance relative to other behavior; the impact of the discovery of anatomical difference; one special way it is affected by parental attitude; and how it contrasts with comparable behavior in the young male. Observation refutes Freud's often quoted statement that masturbation is further removed from the nature of women than of men.

    Alterations in hormone levels during menopause decrease bone density and may worsen oral health, favoring the growth of periodontal pathogens, whose detection could improve the diagnosis of periodontitis. The aim of this study is to detect and quantify the main periodontal pathogens in the oral microbiota of postmenopausal females and to explore the relationship between clinical and periodontal parameters. This was an observational cross-sectional study of 76 postmenopausal females. Dental examinations and sampling for microbiologic evaluation were performed, and a history of osteoporosis/osteopenia was collected. Real-time polymerase chain reaction was used for detecting and quantifying Fusobacterium nucleatum (Fn), Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Campylobacter rectus (Cr), and Tannerella forsythia (Tf). The results obtained were subjected to statistical analyses. Statistical significance was defined as P Periodontitis was detected in 77.1% of females with osteoporosis/osteopenia (P >0.05). A significant correlation was found between osteoporosis and missing teeth. T. forsythia and C. rectus were detected in 100% of the samples, Fn and Pg in 98.7%, and Aa in 73.7%. Osteoporosis did not influence the prevalence of periodontitis among postmenopausal females. The presence of periodontopathogenic bacteria was not sufficient to confirm disease. A preventive maintenance program for postmenopausal females, particularly osteoporotic females, who are at greater risk of tooth loss, could minimize the potential effects of bone loss on periodontal tissues.

    The payload of the UFFO (Ultra-Fast Flash Observatory)-pathfinder now onboard the Lomonosov spacecraft (hereafter UFFO/ Lomonosov) is a dedicated instrument for the observation of GRBs. Its primary aim is to capture the rise phase of the optical light curve, one of the least known aspects of GRBs. Fast response measurements of the optical emission of GRB will be made by a Slewing Mirror Telescope (SMT), a key instrument of the payload, which will open a new frontier in transient studies by probing the early optical rise of GRBs with a response time in seconds for the first time. The SMT employs a rapidly slewing mirror to redirect the optical axis of the telescope to a GRB position prior determined by the UFFO Burst Alert Telescope (UBAT), the other onboard instrument, for the observation and imaging of X-rays. UFFO/Lomonosov was launched successfully from Vostochny, Russia on April 28, 2016, and will begin GRB observations after completion of functional checks of the Lomonosov spacecraft. The concept of early GRB photon measurements with UFFO was reported in 2012. In this article, we will report in detail the first mission, UFFO/Lomonosov, for the rapid response to GRB observations.

    Full Text Available Exemplifying the tsunami source immediately after an earthquake is the most critical component of tsunami early warning, as not every earthquake generates a tsunami. After a major under sea earthquake, it is very important to determine whether or not it has actually triggered the deadly wave. The near real-time observations from near field networks such as strong motion and Global Positioning System (GPS allows rapid determination of fault geometry. Here we present a complete processing chain of Indian Tsunami Early Warning System (ITEWS, starting from acquisition of geodetic raw data, processing, inversion and simulating the situation as it would be at warning center during any major earthquake. We determine the earthquake moment magnitude and generate the centroid moment tensor solution using a novel approach which are the key elements for tsunami early warning. Though the well established seismic monitoring network, numerical modeling and dissemination system are currently capable to provide tsunami warnings to most of the countries in and around the Indian Ocean, the study highlights the critical role of geodetic observations in determination of tsunami source for high-quality forecasting.

    Full Text Available Whether we hand over objects to someone, play a team sport, or make music together, social interaction often involves interpersonal action coordination, both during instances of cooperation and entrainment. Neural mirroring is thought to play a crucial role in processing other’s actions and is therefore considered important for social interaction. Still, to date, it is unknown whether interindividual differences in neural mirroring play a role in interpersonal coordination during different instances of social interaction. A relation between neural mirroring and interpersonal coordination has particularly relevant implications for early childhood, since successful early interaction with peers is predictive of a more favorable social development. We examined the relation between neural mirroring and children’s interpersonal coordination during peer interaction using EEG and longitudinal behavioral data. Results showed that 4-year-old children with higher levels of motor system involvement during action observation (as indicated by lower beta-power were more successful in early peer cooperation. This is the first evidence for a relation between motor system involvement during action observation and interpersonal coordination during other instances of social interaction. The findings suggest that interindividual differences in neural mirroring are related to interpersonal coordination and thus successful social interaction.

    With increasing longevity, an ageing population and advances in assisted reproductive technologies (ART), a greater number of women are deciding to have a child and become a mother in their later years. With this social and demographic change, an important social and ethical debate has emerged over whether single and/or married postmenopausal women should have access to ARTs. The aim of this paper is to address this question and review critically the arguments that have been advanced to support or oppose the use of ART by older women. The arguments presented consider the consequences for the individual, the family and wider society. They cover the potential physical and emotional harm to the older woman, the possible impact on the welfare and wellbeing of the future child, and the impact on the norms, values, customs and traditions of society. After reviewing the evidence, and weighing the opposing arguments, this paper concludes that there is no moral justification for a restriction on the use of ART by postmenopausal women. Allowing access to ART for postmenopausal women is an extension of reproductive autonomy and procreative rights in an age where the promotion of agency, autonomy, individual choice and human rights is paramount.

    Full Text Available The objective of this study was to compare the periodontal status in postmenopausal women with osteopenia and osteoporosis. Material and Methods: We examined 43 postmenopausal women aged from 55 to 74 years. Material assessment of bones in every patient was performed by means of dual energy X-ray absorptiometry (DXA from two points on the skeleton – part of the femur neck and between the first and fourth lumbar vertebrae. A lipid blood test was done for patients of both groups. All patients were divided into two groups (the 1st with osteopenia, and the 2nd with osteoporosis. All patients were subjected to an oral clinical examination: the periodontal examination was composed of Plaque Index (PI, Pocket Score (PS, and Papillary Bleeding Index (PBI. X-ray analysis was performed for every patient. Results: The results of the clinical periodontal examination demonstrated that the mean PBI in patients in the 1st group had no significant differences from the PBI in patients in the 2nd group. PI value and PS findings in patients with general osteoporosis also had no statistical differences from the same parameters in patients with osteopenia. Conclusion: Under the circumstances of these patients’ characteristics and within the limits of the present study, we concluded that there is no significant difference in the periodontal status of postmenopausal women with systemic osteopenia and with osteoporosis.

    The current assessment that twentieth-century global temperature change is unusual in the context of the last thousand years relies on estimates of temperature changes from natural proxies (tree-rings, ice-cores etc.) and climate model simulations. Confidence in such estimates is limited by difficulties in calibrating the proxies and systematic differences between proxy reconstructions and model simulations - notable differences include large differences in multi-decadal variability between proxy reconstructions, and big uncertainties in the effect of volcanic eruptions. Because the difference between the estimates extends into the relatively recent period of the early nineteenth century it is possible to compare them with a reliable instrumental estimate of the temperature change over that period, provided that enough early thermometer observations, covering a wide enough expanse of the world, can be collected. By constraining key aspects of the reconstructions and simulations, instrumental observations, inevitably from a limited period, can reduce reconstruction uncertainty throughout the millennium. A considerable quantity of early instrumental observations are preserved in the world's archives. One organisation which systematically made observations and collected the results was the English East-India Company (EEIC), and 900 log-books of EEIC ships containing daily instrumental measurements of temperature and pressure have been preserved in the British Library. Similar records from voyages of exploration and scientific investigation are preserved in published literature and the records in National Archives. Some of these records have been extracted and digitised, providing hundreds of thousands of new weather records offering an unprecedentedly detailed view of the weather and climate of the late eighteenth and early nineteenth centuries. The new thermometer observations demonstrate that the large-scale temperature response to the Tambora eruption and the 1809

    Full Text Available Hormonal changes associated with menopause alter serum lipid levels, which may play an important role in cardiac related disorders associated with menopause. We studied serum lipid profile changes in premenopausal, perimenopausal and postmenopausal females, so as to assess the differences in lipid levels amongst these three groups. The fasting blood samples were collected from 210 healthy volunteers who were allocated into three groups – Group I comprised of young healthy premenopausal females, Group II comprised of healthy perimenopausal females and Group III comprised of healthy postmenopausal females. Blood was collected after overnight fasting of 12 hours in all the subjects for estimation of serum levels of total cholesterol, high density lipoprotein, low density lipoprotein and triglycerides by enzymatic method. Statistically, significant increase was observed in total cholesterol and also in triglycerides and low density level in postmenopausal females as compared to premenopausal women. High density lipoprotein showed non-significant decrease in postmenopausal females.

Those records have been extracted and digitised, providing 273 000 new weather records offering an unprecedentedly detailed view of the weather and climate of the late eighteenth and early nineteenth centuries.

    The new thermometer observations demonstrate that the large-scale temperature response to the Tambora eruption and the 1809 eruption was modest (perhaps 0.5 °C. This provides an out-of-sample validation for the proxy reconstructions – supporting their use for longer-term climate reconstructions. However, some of the climate model simulations in the CMIP5 ensemble show much larger volcanic effects than this – such simulations are unlikely to be accurate in this respect.

    To investigate the association between body mass index and mortality in a large, ICU population and determine if the relationship is observed among a subgroup of patients ordered early enteral nutrition. Retrospective cohort study within a national clinical mixed ICU database of patients admitted between January 1, 2008, and June 30, 2015. Initial ICU admissions among patients monitored by tele-ICU programs and recorded in the Philips eICU Research Institute database. A total of 1,042,710 adult patient stays with ICU length of stay more than 24 hours, of which 74,771 were ordered enteral nutrition within the first 48 hours. None. Patient stays from 409 ICUs were included. The average age, Acute Physiology and Chronic Health Evaluation IV score, and hospital mortality were 63.6 years, 56.7, and 9.0%, respectively. Hospital mortality among body mass index categories was estimated by multivariable modified Poisson regression models. Compared with the body mass index category 25.0-29.9 kg/m, hospital mortality was higher among underweight (body mass index, obese (body mass index, ≥ 50.0; relative risk, 1.10; 95% CI, 1.05-1.15). However, the risk was not statistically different from patients with body mass index 30.0-49.9 kg/m. Among patients ordered early enteral nutrition, the risk of mortality in the body mass index category 25.0-29.9 kg/m was not statistically different from those in the normal weight or extremely obese groups. A survival advantage for overweight and obese patients was observed in this large cohort of critically ill patients. However, among those ordered early enteral nutrition, the survival disadvantage for body mass index categories less than 25.0 kg/m was minimal or unobservable when compared with higher body mass index categories.

  11. A new approach for tsunami early warning using tsunami observations in a source region

    After the 2011 devastating Tohoku tsunami, improvement of tsunami early warning system is one of key issues in Japan. Japanese government was decided to install 125 ocean bottom pressure sensors and seismometers with a cable system along the Japan and Kurile trench. Each sensor is separated by 30km. We should develop a new approach for real-time tsunami forecast using those newly available data combined with GNSS data or seismic data. A well-recognized problem to use tsunami data at pressure sensors on the top of tsunami source area is a fact that a large vertical coseismic deformation due to a large earthquake cannot be observed at those sensors. The sensors observe a tsunami wave when it starts to propagate. Because of that problem, GSNN data or seismic data are typically used to estimate the coseismic deformation for the tsunami numerical simulation. In this paper, we develop a new technique, which solve the problem. Our technique uses the observations at pressure sensors on the tsunami source area as an input to compute the tsunami directly. Actual tsunami heights at the sensors on the source area is unknown because the cosismic vertical deformation is unknown. However, we can observe directly the time derivative of tsunami heights at those sensors. Time derivatives of tsunami heights at each point are used as inputs to compute the tsunami height distribution in the calculated area. Then we can numerically compute a tsunami using a traditional finite difference technique from the tsunami height distribution computed. For numerical test, first, we compute the synthetic tsunamis using the fault model with 1 minute grid system. The computed tsunami waveforms at 15 minutes x 15 minutes grid points are used as the observed data for this new technique. Each observed point is separated by 15 minutes, about 30km. The result show that the accuracy of tsunami computation is good enough for tsunami forecast. Tsunami generation with a long duration, such as tsunami

    Drought early warning science, in support of famine prevention, is a rapidly advancing field that is helping to save lives and livelihoods. In 2015-2017, a series of extreme droughts afflicted Ethiopia, Southern Africa, Eastern Africa in OND and Eastern Africa in MAM, pushing more than 50 million people into severe food insecurity. Improved drought forecasts and monitoring tools, however, helped motivate and target large and effective humanitarian responses. Here we describe new science being developed by a long-established early warning system - the USAID Famine Early Warning Systems Network (FEWS NET). FEWS NET is a leading provider of early warning and analysis on food insecurity. FEWS NET research is advancing rapidly on several fronts, providing better climate forecasts and more effective drought monitoring tools that are being used to support enhanced famine early warning. We explore the philosophy and science underlying these successes, suggesting that a modal view of climate change can support enhanced seasonal prediction. Under this modal perspective, warming of the tropical oceans may interact with natural modes of variability, like the El Niño-Southern Oscillation, to enhance Indo-Pacific sea surface temperature gradients during both El Niño and La Niña-like climate states. Using empirical data and climate change simulations, we suggest that a sequence of droughts may commence in northern Ethiopia and Southern Africa with the advent of a moderate-to-strong El Niño, and then continue with La Niña/West Pacific related droughts in equatorial eastern East Africa. Scientifically, we show that a new hybrid statistical-dynamic precipitation forecast system, the FEWS NET Integrated Forecast System (FIFS), based on reformulations of the Global Ensemble Forecast System weather forecasts and National Multi-Model Ensemble (NMME) seasonal climate predictions, can effectively anticipate recent East and Southern African drought events. Using cross-validation, we

    We report Advanced Satellite for Cosmology and Astrophysics (ASCA) 0.3-10 keV and X-ray observations of three early type galaxies, NGC 4472, NGC 4406, and NGC 4636. The extended mission in these galaxies is well described by thin thermal eimssion from hot gas. The gas temperature is 0.92 +/- 0.02 keV for NGC 4472, 0.79 +/- 0.01 keV for NGC 4406, and 0.73 +/- 0.02 keV for NGC 4636. The metal abundance for NGC 4472, NGC 4406, and NGC 4636 are, under the assumption of solar ratios, 0.63 +/- 0.15, 0.45 +/- 0.10, and 0.38 +/- 0.07, respectively. Detailed analysis has allowed determination of the abundances of oxygen, silicon, sulfur, and iron. The observed abundances are consistent with the solar ratios. For NGC 4472 and NGC 4406 we also determined the mean temperature of the gas producing the Si lines from the ratio of the Si H to He-like lines and find it to be consistent with the continuum temperature. The X-ray temperature is in good agreement with the observed optical velocity dispersion, stellar density profile, and gas density profile. Our data indicates that the supernova rate should be less than one fifth of the nominal rate in early type galaxies. We derive the mass of these systems within fixed angular scales and find that M/L greater than 40, confirming that elliptical galaxies are dark matter dominated at large radii.

    Full Text Available Apoptosis is a natural process which accompanies human ovary from the moment of birth until old age. While it is a well-known process at the reproductive age, it still needs to be thoroughly examined when referring to the postmenopausal age. The study involved 30 postmenopausal women who had their ovaries removed by laparotomy due to nonneoplastic diseases of the uterus. The women were divided into 3 groups depending on the time that had passed since the last menstruation. Group A consisted of women who had their last menstruation no more than 5 years earlier. In group B menopause occurred 5 to 10 years earlier. Group C was composed of patients who had the last menstruation over 10 years earlier. In all the patients concentrations of follitropin (FSH and estradiol (E2 in blood plasma were measured. Ovarian tissue was obtained during surgery. For morphological studies, ovaries were fixed in Bouin's solution and 4% formalin and embedded in paraffin. Morphological analysis was carried out after hematoxylin-eosin (H-E staining. For histochemical detection of apoptotic cells (in situ localization of fragment DNA, the TUNEL method was used. The expression of caspase-3 positive cells was determined immunohistochemically in paraffin-embedded specimens. Comparing to groups A and B, the ovaries in group C contained small number of corpora albicantia located in the medullary part as well as thinned blood vessels and few lymphatic vessels and nerves. In contrast to group A where the number of TUNEL-positive cells was high and caspase-3 expression was observed, no TUNEL-positive nuclei and caspase-3 expression were found in the examined ovaries of group C women.

    Full Text Available Background: Periodontitis and osteoporosis are two diseases found worldwide and increase in intensity with increasing age of the patients. The severity of osteoporosis and periodontitis are found to be more in women during menopause. The aim of this study was to assess and correlate osteoporosis and periodontal disease among post-menopausal women. Materials and Methods: The study consisted of 94 postmenopausal women in the age range of 45–65 years. All the women underwent dual-energy X-ray absorptiometry (DXA scan to measure bone mineral density (BMD and were graded as normal, osteopenic, and osteoporotic based on the T score obtained. Data regarding patient's educational level, socioeconomic status (SES, and body mass index (BMI was recorded. A detailed periodontal examination was carried out using clinical parameters such as oral hygiene index (OHI, plaque Index (PI, probing pocket depth , and clinical attachment loss to check the level of periodontitis. The level of osteoporosis was correlated with the level of periodontitis. Results: The DXA scan revealed that four women were normal, 44 were osteopenic and 46 were osteoporotic. There was no association found between BMD and OHI, PI, educational status, SES, and BMI. Slight periodontitis was observed in eight women, moderate periodontitis in 62, and severe periodontitis in 24 women. Result suggests that there was a statistical correlation between periodontitis and osteoporosis (P = 0.045. Conclusion: There is a definite correlation found between the severity of periodontitis and osteoporosis among postmenopausal women. A close cooperation between general practitioners and dentists in early diagnosis and treatment of both the diseases will reduce the risk and morbidity among postmenopausal women.

    The Ross Sea sea ice cover is one of the few regions of the cryosphere that have been expanding in recent decades. However, 2017 saw a significantly delayed autumn ice advance and record low early winter sea ice extent. Understanding the causes and impacts of this variability has been hampered by a lack of in situ observations. A winter cruise into the Ross Sea in April-June 2017 provided some of the only in situ winter observations of sea ice processes in this region in almost 20 years. We present a first look at data from arrays of drifting buoys deployed in the ice pack and outflow from these polynyas, supplemented by a suite of high-resolution synthetic aperture radar (SAR) data. Additional observations included high-resolution sonar imagery of ice deformation features from an autonomous underwater vehicle, shipboard visual observations of sea ice properties, and in situ measurements of snow and thickness and structural properties. These data show that the delay in ice advance led to a thin, highly dynamic sea ice pack, with substantial ice production and export from the Ross Ice Shelf and Terra Nova Bay polynyas. Despite these high rates of ice production, the pack ice remained thin due to rapid export and northward drift. Compared to the only prior winter observations made in 1995 and 1998, the ice was thinner, with less ridging and snow cover, reflecting a younger ice cover. Granular ice was less prevalent than in these prior cruises, particularly in the outer pack, likely due to less snow ice formation and less pancake ice formation at the advancing ice edge. Despite rapid basal ice growth, the buoy data suggest that deformation may be the dominant mechanism for sea ice thickening in the pack once an initial ice cover forms.

    To observe the correlation of the postanaesthesia recovery score (PARS) with the incidence, and severity of early postoperative hypoxaemia in children, 1213 infants and children, ASA physical status I, aged three months to 14 years, scheduled for elective plastic surgery were included in this study. Arterial oxygen saturation (Spo2) levels were recorded while children were breathing room air shortly after arrival in the recovery room (0 min), and 5, 10, 15, 20, 30, 40, 50, 60, 120 and 180 min thereafter. The PARS was also determined on all patients when Spo2 levels were recorded in the recovery room. On the basis of different PARS, children were divided into the three groups: Group 1-children having the PARS of postoperative period, the incidence and severity of hypoxaemia correlated closely with the PARS. The lower the children's PARS, the higher the incidences of hypoxaemia (Spo2 = 86-90%) and severe hypoxaemia (Spo2 routine oxygen supplement because hypoxaemia will not occur.

    To evaluate the influence of an exercise programme on postmenopausal women with symptoms of anxiety and depression. The menopause is a period of hormonal changes when mood variations are probably more severe than at any other period of women's lives. Prospective study with control group and pre- and post-treatment measures, after six months treatment. Conducted at two healthcare clinics, in the province of Granada (Spain). A convenience sample of 60 postmenopausal women aged 60-70 years, with symptoms of depression and anxiety, was recruited. The women were randomly divided into two groups: (1) control group, no treatment (n = 30); (2) exercise group, which carried out a programme of mixed physical exercises with musical support (n = 30). All subjects answered questionnaires for the Hamilton Anxiety Scale and the Brink and Yesavage Geriatric Depression Scale before and after treatment. In the exercise group, statistically significant improvements were observed in subjects with moderate and severe depression (18 and 22%, respectively) and in those with symptoms of anxiety. No such changes were observed in the control group. A controlled programme of physical exercise for postmenopausal women alleviates symptoms of anxiety and depression, and its inclusion in primary healthcare programmes should be considered. Menopausal women may benefit from physical exercise, which attenuates the effects of the physiological and psychological changes associated with the menopause and prevents pathologic changes. © 2012 Blackwell Publishing Ltd.

    Objectives The rarity of early diffuse cutaneous systemic sclerosis (dcSSc) makes randomised controlled trials very difficult. We aimed to use an observational approach to compare effectiveness of currently used treatment approaches. Methods This was a prospective, observational cohort study of early dcSSc (within three years of onset of skin thickening). Clinicians selected one of four protocols for each patient: methotrexate, mycophenolate mofetil (MMF), cyclophosphamide or ‘no immunosuppressant’. Patients were assessed three-monthly for up to 24 months. The primary outcome was the change in modified Rodnan skin score (mRSS). Confounding by indication at baseline was accounted for using inverse probability of treatment (IPT) weights. As a secondary outcome, an IPT-weighted Cox model was used to test for differences in survival. Results Of 326 patients recruited from 50 centres, 65 were prescribed methotrexate, 118 MMF, 87 cyclophosphamide and 56 no immunosuppressant. 276 (84.7%) patients completed 12 and 234 (71.7%) 24 months follow-up (or reached last visit date). There were statistically significant reductions in mRSS at 12 months in all groups: −4.0 (−5.2 to −2.7) units for methotrexate, −4.1 (−5.3 to −2.9) for MMF, −3.3 (−4.9 to −1.7) for cyclophosphamide and −2.2 (−4.0 to −0.3) for no immunosuppressant (p value for between-group differences=0.346). There were no statistically significant differences in survival between protocols before (p=0.389) or after weighting (p=0.440), but survival was poorest in the no immunosuppressant group (84.0%) at 24 months. Conclusions These findings may support using immunosuppressants for early dcSSc but suggest that overall benefit is modest over 12 months and that better treatments are needed.

    As early childhood education (ECE) centers become a more common setting for nutrition interventions, a variety of data collection methods are required, based on the center foodservice. ECE centers that require parents to send in meals and/or snacks from home present a unique challenge for accurate nutrition estimation and data collection. We present an observational methodology for recording the contents and temperature of preschool-aged children's lunchboxes and data to support a 2-day vs a 3-day collection period. Lunchbox observers were trained in visual estimation of foods based on Child and Adult Care Food Program and MyPlate servings and household recommended measures. Trainees weighed and measured foods commonly found in preschool-aged children's lunchboxes and practiced recording accurate descriptions and food temperatures. Training included test assessments of whole-grain bread products, mixed dishes such as macaroni and cheese, and a variety of sandwich preparations. Validity of the estimation method was tested by comparing estimated to actual amounts for several distinct food types. Reliability was assessed by computing the intraclass correlation coefficient for each observer as well as an interrater reliability coefficient across observers. To compare 2- and 3-day observations, 2 of the 3 days of observations were randomly selected for each child and analyzed as a separate dataset. Linear model estimated mean and standard error of whole grains, fruits and vegetables, and amounts of energy, carbohydrates, protein, total fat, saturated fat, dietary fiber, thiamin, riboflavin, niacin, vitamins A and C, calcium, iron, sodium, and dietary fiber per lunch were compared across the 2- and 3-day observation datasets. The mean estimated amounts across 11 observers were statistically indistinguishable from the measured portion size for each of the 41 test foods, implying that the visual estimation measurement method was valid: intraobserver intraclass correlation

    Health visitors need competences to promote healthy early parent-infant relationships. The aims of this study were to explore whether there are differences between groups of health visitors with and without additional parenting program education in terms of their knowledge of infant-parent interaction and their observation and assessment skills of such interactions. The cross-sectional study included 36 health visitors' certified Marte Meo therapists and 85 health visitors without additional parenting program education. Health visitors' observation skills were measured assessing five video-recorded mother-infant interactions. A questionnaire was used to measure their intention, self-efficacy, and knowledge. More certified Marte Meo therapists than health visitors without additional parenting program education reported a significantly higher mean level of knowledge of the early relationship, 6.42 (95% CI; 6.18-6.66) versus 5.05 (95% CI; 4.86-6.10), p = .04; and more certified Marte Meo therapists than health visitors without additional parenting program education reported a higher mean level of knowledge of infant self-regulation, 2.44 (95% CI; 2.18-2.71) versus 1.83 (95% CI; 1.62-2.03), p < .001. In the latter group, 54% (95% CI; 0.43-0.64) reported a significantly higher need for further education versus 22% (95% CI; 0.11-0.39), p = .001. Compared to health visitors without any parenting program education, health visitors certified as Marte Meo therapists reported a significantly higher frequency of correct assessment of mothers' sensitivity in two of five video-recordings, with 77.78% (95% CI; 0.61-0.87) compared to 45.88% (95% CI; 0.35-0.57) in Video 3, p = .001, and 69.44% (95% CI; 0.52-0.82) compared to 49.41% (95% CI; 0.39-0.60) in Video 4, p = .04, respectively. The results of the present study support the use of video-based education of health visitors to increase their knowledge of and skills in assessing parent-infant interactions. Randomized controlled

    Since breast cancer is the most common cancer among Japanese women, research leading to its prevention and early detection is important, and many studies have reported a relationship between this cancer and obesity. In addition, it has been reported that the risk of breast cancer posed by obesity differs between pre- and post-menopausal patients. In this study, we investigated the difference in the amount of body fat between pre- and post-menopausal breast cancer patients by measuring the areas of total, visceral, and subcutaneous fat on CT images acquired at the level of the umbilicus. The subjects were 136 women, comprising 63 with breast cancer (21 pre- and 42 post-menopausal) and 73 with other diseases (31 pre- and 42 post menopausal). We found that post-menopausal women with breast cancer had a significantly greater amount of fat than their pre-menopausal counterparts, presumably attributable to the action of estrogen. These results suggest that fat accumulation in post-menopausal women increases the risk of breast cancer. (author)

    Full Text Available The aim of this study was to assess complaints about sleep quality and to investigate circadian rhythms of melatonin secretion in peri- and postmenopausal women. Material and Methods: A total of 146 climacteric women were examined. All patients were divided into 2 groups: Group1 included 72 perimenopausal women and Group 2 included 74 postmenopausal women. Women were surveyed with special questionnaires: PSQI, FFS, ESS, Daytime Feeling and Functioning Scale. Insomnia Severity Index was calculated. Salivary melatonin content was determined (4 times a day by immunoassay using Microplate Reader EL×808 (USA. Results: Perimenopausal women often complained about difficulties falling asleep (more than 20 minutes from the moment the light was turned off and difficulties awakening in the morning, while postmenopausal women often complained about snoring and frequent awakenings during sleep(≥2 times. ISI was 21.3±0.54 in Group 1 and 24.8±0.31 in Group 2, which corresponded to insomnia. Daily melatonin secretion in perimenopausal patients with insomnia was altered – the maximal level was registered in the morning hours. The circadian rhythms of melatonin secretion in the group of postmenopausal women did not correlate to the occurrence of insomnia. Conclusion: We can recommend administration of melatonin in the evening time and light therapy in the early morning hours in the complex treatment of SDs in perimenopausal women for normalizing and shifting the chronobiological rhythms of melatonin secretion, and specific therapy is aimed to eliminate snoring for postmenopausal women.

    Full Text Available Early, efficient and inexpensive methods for the detection of pulmonary tuberculosis are urgently needed for effective patient management as well as to interrupt transmission. These methods to detect M. tuberculosis in a timely and affordable way are not yet widely available in resource-limited settings. In a developing-country setting, we prospectively evaluated two methods for culturing and detecting M. tuberculosis in sputum. Sputum samples were cultured in liquid assay (micro broth culture in microplate wells and growth was detected by microscopic observation, or in Löwenstein-Jensen (LJ solid media where growth was detected by visual inspection for colonies. Sputum samples were collected from 321 tuberculosis (TB suspects attending Bugando Medical Centre, in Mwanza, Tanzania, and were cultured in parallel. Pulmonary tuberculosis cases were diagnosed using the American Thoracic Society diagnostic standards. There were a total of 200 (62.3% pulmonary tuberculosis cases. Liquid assay with microscopic detection detected a significantly higher proportion of cases than LJ solid culture: 89.0% (95% confidence interval [CI], 84.7% to 93.3% versus 77.0% (95% CI, 71.2% to 82.8% (p = 0.0007. The median turn around time to diagnose tuberculosis was significantly shorter for micro broth culture than for the LJ solid culture, 9 days (interquartile range [IQR] 7-13, versus 21 days (IQR 14-28 (p<0.0001. The cost for micro broth culture (labor inclusive in our study was US $4.56 per sample, versus US $11.35 per sample for the LJ solid culture. The liquid assay (micro broth culture is an early, feasible, and inexpensive method for detection of pulmonary tuberculosis in resource limited settings.

    We discovered two transient events in the Kepler field with light curves that strongly suggest they are type II-P supernovae (SNe II-P). Using the fast cadence of the Kepler observations we precisely estimate the rise time to maximum for KSN2011a and KSN2011d as 10.5 ± 0.4 and 13.3 ± 0.4 rest-frame days, respectively. Based on fits to idealized analytic models, we find the progenitor radius of KSN2011a (280 ± 20 R ⊙ ) to be significantly smaller than that for KSN2011d (490 ± 20 R ⊙ ), but both have similar explosion energies of 2.0 ± 0.3 × 10 51 erg. The rising light curve of KSN2011d is an excellent match to that predicted by simple models of exploding red supergiants (RSG). However, the early rise of KSN2011a is faster than the models predict, possibly due to the supernova shock wave moving into pre-existing wind or mass-loss from the RSG. A mass-loss rate of 10 −4 M ⊙ yr −1 from the RSG can explain the fast rise without impacting the optical flux at maximum light or the shape of the post-maximum light curve. No shock breakout emission is seen in KSN2011a, but this is likely due to the circumstellar interaction suspected in the fast rising light curve. The early light curve of KSN2011d does show excess emission consistent with model predictions of a shock breakout. This is the first optical detection of a shock breakout from a SNe II-P

    We have analyzed 17 early-type galaxies, 13 ellipticals and 4 S0 galaxies, observed with Suzaku, and investigated metal abundances (O, Mg, Si, and Fe) and abundance ratios (O/Fe, Mg/Fe, and Si/Fe) in the interstellar medium (ISM). The emission from each on-source region, which is four times the effective radius, r e , is reproduced with one-temperature (1T) or two-temperature (2T) thermal plasma models as well as a multi-temperature model, using APEC plasma code version 2.0.1. The multi-temperature model gave almost the same abundances and abundance ratios with the 1T or 2T models. The weighted averages of the O, Mg, Si, and Fe abundances of all the sample galaxies derived from the multi-temperature model fits are 0.83 ± 0.04, 0.93 ± 0.03, 0.80 ± 0.02, and 0.80 ± 0.02 solar, respectively, in solar units according to the solar abundance table by Lodders in 2003. These abundances show no significant dependence on the morphology and environment. The systematic differences in the derived metal abundances between versions 2.0.1 and 1.3.1 of the APEC plasma codes were investigated. The derived O and Mg abundances in the ISM agree with the stellar metallicity within an aperture with a radius of one r e derived from optical spectroscopy. From these results, we discuss the past and present Type Ia supernova rates and star formation histories in early-type galaxies.

Our purpose was to study the impact of medications on such early rehospitalizations. Patients and methods: This is a clinical, prospective, observational study on rehospitalizations within 30 days after an acute hospital episode for frail patients over the age of 75 years. To identify adverse drug reactions (ADRs, underuse of evidence-based treatment and avoidability of rehospitalizations, the Naranjo score, the Hallas criteria and clinical judgment were used. Results: Of 390 evaluable patients, 96 (24.6% were rehospitalized. The most frequent symptoms and conditions were dyspnea (n = 25 and worsened general condition (n = 18. The most frequent diagnoses were heart failure (n = 17 and pneumonia/acute bronchitis (n = 13. By logistic regression analysis, independent risk predictors for rehospitalization were heart failure (odds ratio [OR] = 1.8; 95% CI = 1.1–3.1 and anemia (OR = 2.3; 95% CI = 1.3–4.0. The number of rehospitalizations due to probable ADRs was 13, of which two were assessed as avoidable. The number of rehospitalizations probably due to underuse of evidence-based drug treatment was 19, all of which were assessed as avoidable. The number of rehospitalizations not due to ADRs or underuse of evidence-based drug treatment was 64, of which none was assessed as avoidable. Conclusion: One out of four

    This study aimed to evaluate the association of abdominal obesity, apolipoprotein and insulin resistance (IR) with the risk of hypertension in postmenopausal women. We analyzed a total of 242 women aged between 35 and 70 years. Blood pressure (BP), anthropometric indices, lipid profile, fasting glucose, insulin, C-reactive protein (CRP) and apolipoprotein concentrations were measured. Homeostasis model assessment (HOMA) was used to assess IR. Hypertension was defined as a systolic BP (SBP) ≥140 mmHg and/or diastolic BP (DBP) ≥90 mmHg or current treatment with antihypertensive drugs. Women with hypertension showed significantly higher mean values of age, SBP and DBP, waist circumference (WC), fasting plasma glucose (FPG), insulin, HOMAIR and the apolipoprotein B (apoB). When analyses were done according to the menopausal status, higher prevalence of hypertension was observed in postmenopausal women (72.8% vs. 26.0%, p menopause (p = 0.008) were significantly associated with higher risk for hypertension. These results suggest that changes in WC, apoB and IR accompanying menopause lead to a greater prevalence of hypertension in postmenopausal women.

    Background: Postmenopausal bleeding (PMB) is bleeding occurring after 6-12 months of amenorrhea in a woman of age where the menopause can be expected. Objectives of this study were to ascertain various causes and prevalence of genital organ malignancy in patients presenting with postmenopausal bleeding. Methods: A prospective observational study carried out in the Department of Obstetrics and Gynaecology, Fauji Foundation Hospital, Rawalpindi comprising of 167 consecutive cases presenting with postmenopausal bleeding one year after menopause. Women having undergone hysterectomy and bilateral salpingo-oophorectomy, receiving radiotherapy or chemotherapy, suffered trauma to the genital tract, having coagulation disorder or on anticoagulant or hormone replacement therapy were excluded. Detailed history was obtained and a thorough clinical examination was conducted. Data were entered into hospital computer database (Medix) system. Mean +- SD were calculated for age, percentage was calculated for types of histopathological findings. Results: The commonest cause of PMB was atrophic endometritis and vaginitis 33 (21.2%). Overall incidence of various genital tract malignancies was 25 (16.0%). Conclusion: The overall incidence of genital tract malignancies in patients presenting with PMB is high (16.0%), therefore, it needs to be taken seriously and requires prompt and thorough investigations.

    The prevalence of secondary processes in women with postmenopausal osteoporosis (OP) is not well known. The aim of this study was to analyze the prevalence of conditions contributing to bone loss in postmenopausal women with OP and to evaluate the clinical characteristics and the impact of these disorders on the severity of the disease. A total of 204 postmenopausal women (mean +/- SD age, 64.9 +/- 10 y) with OP were prospectively included. None had an evident secondary cause of OP. Bone mineral density assessment, spine x-ray, and laboratory tests including parathormone (PTH), 25-hydroxyvitamin D (25OHD), thyroid hormones, urinary N-terminal cross-linked telopeptide of type I collagen (NTx), and 24-hour urinary calcium and cortisol were performed in all participants before treatment. As a group, 82% had low 25OHD levels (65 pg/mL), and 20% had hypercalciuria (>250 mg/24 h). In addition, 41% had increased NTx urinary levels (>65 nmol/mmol). PTH levels were related to age and were higher in women with femoral Z score less than -2.0 (80.3 pg/mL vs 57.7 pg/mL; P = 0.03). Participants with increased urinary NTx showed lower lumbar T and Z scores, whereas women with low 25OHD levels had lower femoral neck bone mineral density and T score values. In addition, participants with vertebral fractures had higher prevalence of 25OHD levels less than 20 ng/mL (69.2% vs 53.4%; P < 0.05). Secondary processes that contribute to low bone mass in postmenopausal women with OP are frequent, especially vitamin D insufficiency, increased PTH values, and hypercalciuria. In addition, increased bone resorption is frequently observed in this group of women. Most of these processes contributed to the severity of the disease.

    Diabetes mellitus is a common disease. Similarly, ultrasound findings of fatty change and renal crystals are commonly seen on ultrasound. In the personal observation of the main author over the past so many years it was noticed that Diabetes Mellitus, Fatty liver and renal crystals all sit well together. This study tries to establish a relationship between diabetes mellitus renal echogenic foci and fatty liver. This study is first of its kind, as nobody has ever before investigated an association between the renal echogenic foci and fatty liver in relation to diabetes mellitus. Methods: This cross-sectional, observational study was conducted at Radiology Department Combined Military Hospital, Kohat From 2nd June 2013 to 30th May 2014. Three hundred patients were collected on the basis of having fatty liver and renal echogenic foci on ultrasound and three hundred more patients were collected who had no fatty liver or renal echogenic foci on ultrasound. Their labs were done for diabetes mellitus. Results: The patients having renal echogenic foci together with fatty liver had 83% positive rate of being diabetics, while patients with no fatty liver and no echogenic foci on ultrasonography had only 0.6% Positive rate of being diabetics. Conclusion: Our results provided the first demonstration of an association between renal echogenic foci together with fatty liver with the diabetes mellitus. Thus ultrasound examination of abdomen can be helpful in its early diagnosis if we make a protocol of doing fasting and random blood sugars in all those patients who have positive renal echogenic foci and fatty liver on their ultrasound examination.

    The Hubble Space Telescope's Early Release Observations (EROs) were revealed to the public on September 9, 2009, and K-12 students and educators in five states across the country were able to join the celebration. To date, students and educators in Maryland, Ohio, New York, California, and Florida have participated in the Hubble Space Telescope's ERO Pilot Project. This is an interdisciplinary project created by the Space Telecope Science Institute's (STScI) Office of Public Outreach in which students use skills from subject areas such as language arts, science, art, and technology to research the four ERO objects and create compositions. In recognition of their participation, the students' compositions are displayed at host institutions in each state (a museum, science center, school, planetarium or library) during a special public event for participating students, their families, and teachers. As part of its evaluation program, STScI's Office of Public Outreach has been conducting an evaluation of the project to determine the viability and potential of conducting large-scale, formal/informal collaborative projects in the future and to share lessons learned. Lessons learned will be applied to a new interdisciplinary project, the James Webb Space Telescope Student Innovation Project.

    We describe a new Large Program in progress on the Gemini North and South telescopes: Gemini Observations of Galaxies in Rich Early Environments (GOGREEN). This is an imaging and deep spectroscopic survey of 21 galaxy systems at 1 10 in halo mass. The scientific objectives include measuring the role of environment in the evolution of low-mass galaxies, and measuring the dynamics and stellar contents of their host haloes. The targets are selected from the SpARCS, SPT, COSMOS, and SXDS surveys, to be the evolutionary counterparts of today's clusters and groups. The new red-sensitive Hamamatsu detectors on GMOS, coupled with the nod-and-shuffle sky subtraction, allow simultaneous wavelength coverage over λ ˜ 0.6-1.05 μm, and this enables a homogeneous and statistically complete redshift survey of galaxies of all types. The spectroscopic sample targets galaxies with AB magnitudes z΄ cluster members. Combined with existing spectroscopy on the brighter galaxies from GCLASS, SPT, and other sources, GOGREEN will be a large legacy cluster and field galaxy sample at this redshift that spectroscopically covers a wide range in stellar mass, halo mass, and clustercentric radius.

    2013-07-01

    Our hypothesis was that thrombosis occurring in postmenopausal women given testosterone (T) or testosterone-estradiol (TE) to improve libido was associated with a prothrombotic interaction between T or TE with underlying inherited procoagulants. In three previously healthy, postmenopausal, Caucasian women with no antecedent thrombosis and previously undiagnosed G20210A prothrombin gene heterozygosity, hyperhomocysteinemia and 4G4G homozygosity of the PAI-1 gene, we describe central retinal vein thrombosis and osteonecrosis that developed at 16 days, 2 months and 11 months in the three cases, respectively, after T or TE therapy was started. Exogenous T or TE in postmenopausal women may be associated with thrombosis, speculatively when it is superimposed on underlying procoagulants. This small observational case series can serve as a starting point for a larger observational study with greater detail on patient history, serum T and estradiol levels, and detailed PCR and serologic assessment of thrombophilia and hypofibrinolysis.

    Context. The traditional knowledge of the mechanisms that brought to the formation and evolution of early type galaxies (ETG) in a hierarchical Universe was challenged by the unexpected finding by ATLAS3D that 86% ETGs show signs of a fast rotating disk at their interior, implying an origin common to most spiral galaxies, followed by a quenching phase, while only a minority of the most massive systems are slow rotators and were likely to be the products of merger events. Aims: Our aim is to improve our knowledge on the content and distribution of ionised hydrogen and their usage to form stars in a representative sample of ETGs for which the kinematics and detailed morphological classification were known from ATLAS3D. Methods: Using narrow-band filters centered on the redshifted Hα line along with a broad-band (r-Gunn) filter to recover the stellar continuum, we observed or collected existing imaging observations for 147 ETG (including members of the Virgo cluster), representative of the whole ATLAS3D survey. Results: 55 ETGs (37%) were detected in the Hα line above our detection threshold (HαEW ≤ -1 Å) and 21 harbour a strong source (HαEW ≤ -5 Å) . Conclusions: The strong Hα emitters appear associated with mostly low-mass (M* 1010 M⊙) S0 galaxies which contain conspicuous stellar and gaseous disks, harbouring significant star formation at their interior, including their nuclei. The weak Hα emitters are almost one order of magnitude more massive, contain gas-poor disks and harbour an AGN at their centers. Their emissivity is dominated by [NII] and does not imply star formation. The 92 undetected ETGs constitute the majority in our sample and are gas-free systems which lack a disk and exhibit passive spectra even in their nuclei. These pieces of evidence reinforce the conclusion of Cappellari (2016, ARA&A, 54, 597) that the evolution of ETGs followed the secular channel for the less massive systems and the dry merging channel for the most massive

    To observe the clinical effectiveness of warm needling combined with element calcium on postmenopausal osteoporosis, and to explore its action mechanism. Eighty-five postmenopausal patients were randomly divided into an observation group (43 cases) and a control group (42 cases). Both the two groups were treated with oral administration of caltrate-D tablet, 600 mg per day, once a day before sleep for one year. Patients in the observation group were treated with warm needling at Dazhu (BL 11), Shenshu (BL 23), Xuan-zhong (GB 39), once a day; 30 days of treatment were taken as a course, and totally 4 courses were given with an interval of 60 days between courses. The bone mineral density (BMD) of the lumbar vertebra and hip joint, and the level of serum bone gla protein (S-BGP) and hydroxyproline/creatinine (Hyp/Cr) were observed before and after treatment in the two groups. (1)After treatment, the BMD in the observation group was significantly increased [lumbar vertebra (0. 811±0. 024) g/cm2 vs (0. 892±0.019) g/cm2, femoral neck (0. 512±0.014) g/cm2 vs (0. 554±0. 015) g/cm2, femoral trochanter (0. 716±0. 028) g/cm2 vs (0.769±0.026) g/cm2, Ward's trigonum (0. 590±0. 013) g/cm2 vs (0. 660±0. 017) g/cm2, all Posteoporosis is significant, which is likely to be achieved by reducing the bone metabolism of postmenopausal patients.

    Full Text Available Hypertension is a frequent, chronic cardiovascular disease both in industrially developed and developing countries; its frequency ranges between 20 and 40 %. Although the prevalence of hypertension in women is lower than that in men, it reaches 70% to 80% in women above 70 years of age, and is a strong predictor of cardiovascular risk. Osteoporosis (OP is systematic skeletal disorder with lower bone mass and damages of bone tissue microarchitecture. The aim of this study was to ascertain the association between hypertension and osteoporosis as two mass noninfectious deceases.The examination involved three hundred postmenopausal women who came for densitometry inspection; none of them had some major cardiovascular event (myocardial infarction, cerebrovascular stroke and ischemic heart disease. From all of them were taken personal data, personal and familial case histories. The parameters used in the further analysis were: body mass, body height, waist circumference, blood pressure; laboratory analysis: cholesterol, HDL, LDL, glycemia, Ca and P in serum and Ca in urine. In addition, there was calculated a ten-year risk of cardiovascular event according to SCORE system, using tables for high risk; bone mineral density on Hologic Discovery QDR-C was shown as T score on the lumbar part of the spinal column. The patients were divided into tree groups based on the measures of bone density: the patients with osteoporosis - bone density with T score lower than 2.5 SD (100 patients; patients with osteopenia - T score from -1 to -2,5 SD (100, and control group of patients with normal bone density T score from +1 to -1 SD (100.The mean age of postmenopausal women (control group with normal bone density was 54.10±3.90 years; 56.63±4.76 years in the group with osteopenia (group II; and 60.14±3.55 years in the group of postmenopausal women with osteoporosis.The analysis of variance (ANOVA and post hoc Dunett`s test showed that there were statistically

    Postmenopausal osteoporosis is now hypothetically considered to be an autoimmune and inflammatory process in which many pro-inflammatory and T cell-derived cytokines play important roles in the loss of bone mass. For instance, interleukin-2 (IL-2), interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α) secreted by Th1 and IL-6, IL-4, and IL-10 secreted by Th2 have been shown to be involved in the pathogenesis of osteoporosis. Interleukin-17 (IL-17) is a characteristic cytokine secreted by Th17 cells of the CD4 + subgroup. Although IL-17 has been shown to enhance bone resorption in ovariectomized mouse model, bone cells and genetic research, human-related studies of IL-17 are few. According to WHO classification of osteoporosis by the T scores of BMD, the subjects were divided into the postmenopausal osteoporosis group (T scores≤-2.5), the postmenopausal osteopenia group (-2.5 osteoporosis group than in the postmenopausal osteopenia group and the postmenopausal normal BMD group, but the difference between the postmenopausal osteopenia group and the postmenopausal normal BMD group had no statistical significance. IL-17A was negatively correlated with BMD. To our knowledge, we discovered for the first time that serum concentrations of IFN-γ and IL-4 were significantly lower in the postmenopausal osteoporosis group than in the postmenopausal normal BMD group; IFN-γ and IL-4 were positively correlated with BMD. In addition, we also determined that BMI was negatively correlated with BMD; IL-17A was positively correlated with serum calcium. However, no significant differences in IL-6, TNF-α, IL-2, and IL-10 were observed among the three groups; these three factors were not correlated with BMD. Our experiments have confirmed the roles of IL-17 in the pathogenesis of postmenopausal osteoporosis and in the promotion of bone resorption. Targeted therapy of IL-17, IFN-γ, and IL-4 may be beneficial in the treatment of patients with postmenopausal osteoporosis

    We present grism spectra of emission-line galaxies (ELGs) from 0.6 to 1.6 μm from the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope. These new infrared grism data augment previous optical Advanced Camera for Surveys G800L 0.6-0.95 μm grism data in GOODS-South from the PEARS program, extending the wavelength coverage well past the G800L red cutoff. The Early Release Science (ERS) grism field was observed at a depth of two orbits per grism, yielding spectra of hundreds of faint objects, a subset of which is presented here. ELGs are studied via the Hα, [O III], and [O II] emission lines detected in the redshift ranges 0.2 ∼ B(F098M) ≅ 25 mag. Seventeen GOODS-South galaxies that previously only had photometric redshifts now have new grism-spectroscopic redshifts, in some cases with large corrections to the photometric redshifts (Δz ≅ 0.3-0.5). Additionally, one galaxy had no previously measured redshift but now has a secure grism-spectroscopic redshift, for a total of 18 new GOODS-South spectroscopic redshifts. The faintest source in our sample has a magnitude m AB(F098M) = 26.9 mag. The ERS grism data also reflect the expected trend of lower specific star formation rates for the highest mass galaxies in the sample as a function of redshift, consistent with downsizing and discovered previously from large surveys. These results demonstrate the remarkable efficiency and capability of the WFC3 NIR grisms for measuring galaxy properties to faint magnitudes and redshifts to z ∼> 2.

    This study aims to describe time trends in and patterns of use of hormonal contraception and postmenopausal hormone therapy and to identify factors associated with their use among Spanish women. We performed a cross-sectional analysis using data from 1,954 population controls (aged 24-85 y) in 12 provinces of Spain who were enrolled in the Multi Case-Control Spain study (2007-2013). Data were collected from a questionnaire conducted face-to-face by trained personnel. We collected information on sociodemographic factors, lifestyle, sleep patterns, reproductive history, and occupational history. Overall, 48.5% of Spanish women reported ever use of hormonal contraception, and 9.8% of women in the postmenopausal group reported use of postmenopausal hormone therapy. Younger cohorts used hormonal contraception for a longer period, whereas postmenopausal hormone therapy use dramatically dropped in the 2000s. Women with higher education levels (including education of partners) and smoking history were the most probable users of hormonal contraception, whereas inverse associations were observed among housewives, obese women, and nulliparous women. Postmenopausal hormone therapy use was associated with a surgical or therapeutic cause of menopause and with occupational history of rotating shifts. In this Spanish population, several demographic, lifestyle, occupational, and reproductive factors are associated with use of hormonal compounds. Characterizing hormonal users and monitoring trends in the use of these hormonal compounds are essential from a public health perspective.

    Full Text Available The objective of the study was investigation of the relationship between cognitive functions and lipid profile, BMI and change of body weight in postmenopausal women carriers of Apolipoprotein E gene polymorphisms (APOE. A group of 170 women was recruited to the study. The inclusion criteria were: minimum of two years after the last menstruation, FSH concentration 30 U/ml and no signs of dementia on the Montreal Cognitive Assessment (MoCA. A computerized battery of Central Nervous System Vital Signs (CNS VS was used for diagnostic cognitive functions. APOE genotype was performed by multiplex PCR. In blood plasma were determined: triglycerides, total cholesterol and its fractions: HDL cholesterol and LDL cholesterol. Statistical analysis was performed using two-way analysis of variance in STATISTICA software. In the postmenopausal women examined, the carrier state of APOE gene polymorphism was associated with the level of triglycerides, and results concerning three cognitive functions: executive functions, psychomotor speed, and cognitive flexibility. Loss of body weight in postmenopausal women was related with lower results in neurocognitive index and the majority of cognitive functions. The results concerning cognitive functions in postmenopausal women in the study were not significantly related with lipid profile. Significant differences were observed according to APOE gene polymorphism in correlations between LDL/HDL and CHOL/HDL ratios, and results in the processing speed and reaction time, as well as between the BMI and results in processing speed in the postmenopausal women examined.

    Uric acid is a risk factor for coronary artery disease (CAD) in postmenopausal women but the association with inflammation and coronary microvascular endothelial dysfunction (CED) is not well-defined. The aim of this study was to determine the relationship of serum uric acid (SUA), inflammatory markers and CED. In this prospective cohort study, serum uric acid, hsCRP levels, and neutrophil count were measured in 229 postmenopausal women who underwent diagnostic catheterization, were found to have no obstructive CAD and underwent coronary microvascular function testing, to measure coronary blood flow (CBF) response to intracoronary acetylcholine. The average age was 58 years (IQR 52, 66) years. Hypertension was present in 48%, type 2 diabetes mellitus in 5.6%, and hyperlipidemia in 61.8%. CED was diagnosed in 59% of postmenopausal women. Mean uric acid level was 4.7 ± 1.3 mg/dL. Postmenopausal women with CED had significantly higher SUA compared to patients without CED (4.9 ± 1.3 vs. 4.4 ± 1.3 mg/dL; p=0.02). There was a significant correlation between SUA and % change in CBF to acetylcholine (p=0.009), and this correlation persisted in multivariable analysis. SUA levels were significantly associated with increased neutrophil count (p=0.02) and hsCRP levels (p=0.006) among patients with CED, but not those without CED. Serum uric acid is associated with coronary microvascular endothelial dysfunction in postmenopausal women and may be related to inflammation. These findings link serum uric acid levels to early coronary atherosclerosis in postmenopausal women. PMID:27993955

    Menopause, the cessation of menses, occurs with estrogens decline, low-grade inflammation, and impaired endothelial function, contributing to atherosclerotic risk. Intima-media thickness (IMT) is an early subclinical biomarker of atherosclerosis. Inflammation may have a role on symptoms: hot flashes, anxiety, and depressive mood, which also are related to endothelial dysfunction, increased IMT and cardiovascular risk. In this study we compared several inflammatory markers in early vs. late postmenopausal women and studied the association of IMT and symptoms with these markers in the full sample. In a cross-sectional design including 60 women (53.1 ± 4.4 years old) at early and late postmenopause, we evaluated the expression of CD62L, ICAM-1, PSGL-1, CD11b, CD11c, and IL-8R on PBMC by flow cytometry. Serum soluble ICAM-1, sVCAM-1, sCD62E, sCD62P, CXCL8, IL-1β, IL-6, and TNF-α levels were quantified by ELISA. Plasma levels of microparticles (MPs) were determined by FACS. Finally, carotid intima-media thickness (IMT) was measured by ultrasound. We observed that ICAM-1 expression by lymphocytes and serum sVCAM-1 levels were augmented at late postmenopause. Late postmenopause women with severe hot flashes had increased expression of CD62L and IL-8R on neutrophils. By multivariate analysis, the carotid IMT was strongly associated with membrane-bound TNF-α, CD11b expression, Annexin V(+) CD3(+) MPs, LPS-induced NO production, HDL-cholesterol and age. Depressive mood was associated negatively with PSGL-1 and positively with LPS-induced NO. Finally, Log(AMH) levels were associated with carotid IMT, IL-8R expression and time since menopause. IMT and depressive mood were the main clinical features related to vascular inflammation. Aging, hormonal changes and obesity were also related to endothelial dysfunction. These findings provide further evidence for a link between estrogen deficiency and low-grade inflammation in endothelial impairment in mature women.

  16. Observed Effects of Vegetation Growth on Temperature in the Early Summer over the Northeast China Plain

    Full Text Available The effect of vegetation on temperature is an emerging topic in the climate science community. Existing studies have mostly examined the effects of vegetation on daytime temperature (Tmax, whereas this study investigates the effects on nighttime temperature (Tmin. Ground measurements from 53 sites across northeastern China (NEC from 1982 to 2006 show that early summer (June Tmax and Tmin increased at mean rates of approximately 0.61 °C/10 year and 0.67 °C/10 year, respectively. Over the same period, the satellite-based Normalized Difference Vegetation Index (NDVI decreased by approximately 0.10 (accounting for 18% of the climatological NDVI for 1982–1991. It is highlighted that a larger increase in Tmax (Tmin co-occurred spatially with a larger (smaller decrease in NDVI. Deriving from such spatial co-occurrences, we found that the spatial variability of changes in Tmax (i.e., ΔTmax is negatively correlated with the spatial variability of changes in NDVI (i.e., ΔNDVI, while the spatial variability of changes in Tmin (i.e., ΔTmin is positively correlated (r2 = 0.10; p < 0.05 with that of ΔNDVI. Similarly, we detected significant positive correlations between the spatial variability of ΔNDVI and the change in surface latent heat flux (r2 = 0.16; p < 0.01 and in surface air specific humidity (r2 = 0.28; p < 0.001. These findings on the spatial co-occurrences suggest that the vegetation growth intensifies the atmospheric water vapor through evapotranspiration, which enhances the atmospheric downward longwave radiation and strengthens the greenhouse warming effects at night. Thereby, the positive correlation between ΔNDVI and ΔTmin is better understood. These results indicate that vegetation growth may not only exert effects on daytime temperature but also exert warming effects on nighttime temperature by increasing atmospheric water vapor and thus intensifying the local greenhouse effect. This study presents new observation evidence of the

    The objectives of this study were to observe the changes in follicle-stimulating hormone (FSH) and bone mineral density (BMD) in postmenopausal women, to research the relationship between FSH and postmenopausal osteoporosis, and to observe the effects of FSH on osteoclast differentiation in RAW264.7 cells. We analyzed 248 postmenopausal women with normal bone metabolism. A radioimmunoassay (RIA) was used to detect serum FSH, luteinizing hormone (LH), and estradiol (E2). Dual-energy X-ray absorptiometry was used to measure forearm BMD. Then, we analyzed the age-related changes in serum FSH, LH and E2. Additionally, FSH serum concentrations were compared between a group of postmenopausal women with osteoporosis and a control group. Osteoclasts were induced from RAW264.7 cells in vitro by receptor activator of nuclear factor kappa B ligand (RANKL), and these cells were treated with 0, 5, 10, and 20 ng/ml FSH. After the osteoclasts matured, tartrate-resistant acid phosphatase (TRAP) staining was used to identify osteoclasts, and the mRNA expression levels of genes involved in osteoclastic phenotypes and function, such as receptor activator of NF-κB (Rank), Trap, matrix metalloproteinase-9 (Mmp-9) and Cathepsin K, were detected in different groups using real-time PCR (polymerase chain reaction). 1. FSH serum concentrations in postmenopausal women with osteoporosis increased notably compared with the control group. 2. RANKL induced RAW264.7 cell differentiation into mature osteoclasts in vitro. 3. FSH increased mRNA expression of genes involved in osteoclastic phenotypes and function, such as Rank, Trap, Mmp-9 and Cathepsin K, in a dose-dependent manner. The circulating concentration of FSH may play an important role in the acceleration of bone loss in postmenopausal women. FSH increases osteoclastogenesis in vitro.

    2016-01-01

    There is increasing evidence that physical exercise can prevent fractures in postmenopausal women. However, even with careful adaptation of the exercise program to subjects' changing bone, health, and fitness status, effectivity may still decrease over the time. This could be specifically the case where the limitations of higher age collide with the specification of the exercise program. Thus, the aim of this study was to monitor bone mineral density (BMD) changes over a 16-year period of supervised exercise. Our hypothesis was that BMD differences at lumbar spine (LS) and femoral neck (FN) between exercisers (EG) and nontraining controls (CG) increased throughout the intervention with significant differences for each of the four 4-year observation periods. Sixty-seven (EG, n = 39 versus CG, n = 28) initially early-postmenopausal osteopenic women of the Erlangen Fitness and Osteoporosis Prevention Study (EFOPS) with complete BMD data sets for baseline (1998) and 4-, 8-, 12-, and 16-year follow-up were included in the analysis. The exercise protocol initially focused on a high-intensity strategy that addressed bone but increasingly shifted to a more comprehensive intervention. LS-BMD differences between the EG and CG continuously increased (year 4: 2.4% (95%- Confidence Interval 1.0% to 3.8%), year 8: 3.1% (1.6% to 4.7%), year 12: 3.9% (1.9% to 5.8), year 16: 4.5% (2.5% to 6.6%). Correspondingly, rising differences for FN-BMD (0.9% (-0.2% to 2.1%) versus 1.9% (0.4% to 3.3%) versus 2.0% (0.5% to 3.8%) versus 3.0% (1.0% to 5.0%)) were observed. However, in contrast to our hypothesis, group differences within the four 4-year periods were not consistently significant (LS, p = 0.001 to 0.097; FN, p = 0.026 to 0.673); further, BMD kinetics among the groups varied between LS and FN. Of particular importance, significant differences (p ≤ 0.030) for both regions were still found in the final period. We conclude that exercise-even when adapted for subjects' decreasing bone

    Full Text Available This paper presents a hybrid model for early onset prediction of driver fatigue, which is the major reason of severe traffic accidents. The proposed method divides the prediction problem into three stages, that is, SVM-based model for predicting the early onset driver fatigue state, GA-based model for optimizing the parameters in the SVM, and PCA-based model for reducing the dimensionality of the complex features datasets. The model and algorithm are illustrated with driving experiment data and comparison results also show that the hybrid method can generally provide a better performance for driver fatigue state prediction.

  7. The role of cytokines in postmenopausal osteoporosis.

    2014-08-01

    Postmenopausal osteoporosis is a silent systemic progressive disease characterised by a decrease in bone mass per unit volume. This condition compromises the physical strength of the skeleton and increases the susceptibility to fractures on minor trauma. The imbalance between bone formation and bone resorption is known to be responsible for postmenopausal bone loss. Estrogen deficiency contributes to bone loss by increasing the production of pro-inflammatory cytokines by bone marrow and bone cells. Clinical and molecular evidence indicates that estrogen-regulated cytokines exert regulatory effects on bone turnover implicating their role as being the primary mediators of the accelerated bone loss at menopause. The current perspective on the role and interaction of cytokines such as IL-1, IL-4, IL-6, IL-17, TNF, IFN-γ and TGF-β in bone loss linked with estrogen deficiency is reviewed. Current treatment options and emerging drug therapies in the management of postmenopausal osteoporosis are also evaluated.

  8. A-FABP Concentration Is More Strongly Associated with Cardiometabolic Risk Factors and the Occurrence of Metabolic Syndrome in Premenopausal Than in Postmenopausal Middle-Aged Women

    Full Text Available We aimed at the evaluation of the relationship between adipocyte fatty acid binding protein (A-FABP and cardiometabolic risk factors in premenopausal and postmenopausal women. Additionally, we compared A-FABP with adipokines related to metabolic syndrome (MetS such as leptin and adiponectin. 94 premenopausal and 90 early postmenopausal middle-aged Caucasian women were subject to examinations. Postmenopausal women had higher A-FABP than premenopausal; this difference became insignificant after controlling for age. We found significantly higher correlation coefficients between A-FABP and TC/HDL-C ratio and number of MetS components in premenopausal women, compared to postmenopausal. Each 1 ng/dL increase in A-FABP concentration significantly increased the probability of occurrence of atherogenic lipid profile in premenopausal women, even after multivariate adjustment. All odds ratios became insignificant after controlling for BMI in postmenopausal women. A-FABP was more strongly associated with MetS than leptin and adiponectin in premenopausal women. Adiponectin concentration was a better biomarker for MetS after menopause. Our results suggest that the A-FABP is more strongly associated with some cardiometabolic risk factors in premenopausal than in postmenopausal women. Higher values of A-FABP after menopause are mainly explained by the fact that postmenopausal women are older. Because of the limitation of study, these results should be interpreted with caution.

    Coercion theory posits a cyclical relationship between harsh and coercive parent-child interactions and problem behavior beginning in early childhood. As coercive interactions have been theorized and found to facilitate the development and growth of early conduct problems, early interventions often target parenting to prevent or reduce early disruptive problem behavior. This study utilizes direct observations of parent-child interactions from the Early Steps Multisite study (N = 731; 369 boys) to examine the effect of the Family Check-Up, a family-centered intervention program, on measures of parent-child positive engagement and coercion from age 2 through 5, as well as on childhood problem behavior at age 5. Results indicate that high levels of parent-child positive engagement were associated with less parent-child coercion the following year, but dyadic coercion was unrelated to future levels of positive engagement. In addition, families assigned to the Family Check-Up showed increased levels of positive engagement at ages 3 and 5, and the association between positive engagement at age 3 and child problem behavior at age 5 was mediated by reductions in parent-child coercion at age 4. These findings provide longitudinal confirmation that increasing positive engagement in parent-child interaction can reduce the likelihood of coercive family dynamics in early childhood and growth in problem behavior.

    Objectives We tested the hypothesis that oxidative stress contributes to reductions in left ventricular diastolic function in estrogen-deficient postmenopausal women, related in part to reduced nitric oxide (NO) bioavailability. Study design LV diastolic function – recorded using transthoracic echocardiography and determined as the peak early (E) to late (A) mitral inflow velocity ratio and the E to peak early (e’) mitral annular velocity ratio – and brachial artery flow mediated dilation (FMD), a biomarker of NO bioavailability, were measured during acute systemic infusions of saline (control) and ascorbic acid (experimental model to decrease oxidative stress) in healthy premenopausal women (N=14, 18-40 years) and postmenopausal women (N=23, 45-75 years). Results The E/A ratio was lower (1.16[1.06−1.33] vs 1.65[1.5−2.3]; median[interquartile range]) and the E/e’ ratio was elevated (8.8[7.6−9.9] vs. 6.6[5.5−7.3]) in postmenopausal compared with premenopausal women, indicating reduced LV diastolic function. E/A and E/e’ were correlated with FMD (r=0.54 and r=−0.59, respectively, both PAscorbic acid infusion improved both FMD (5.4±2.0% to 7.8±2.6%) and E/e’ (to 8.1[7.2−9.7], P=0.01) in postmenopausal women but not in premenopausal women. Ascorbic acid did not change E/A in either group. Conclusion The current study provides evidence that oxidative stress contributes to reduced LV diastolic function in estrogen-deficient postmenopausal women, possibly by reducing the availability of NO.

  13. The potential role of real-time geodetic observations in tsunami early warning

    Science.gov (United States)

    Tinti, Stefano; Armigliato, Alberto

    2016-04-01

    Tsunami warning systems (TWS) have the final goal to launch a reliable alert of an incoming dangerous tsunami to coastal population early enough to allow people to flee from the shore and coastal areas according to some evacuation plans. In the last decade, especially after the catastrophic 2004 Boxing Day tsunami in the Indian Ocean, much attention has been given to filling gaps in the existing TWSs (only covering the Pacific Ocean at that time) and to establishing new TWSs in ocean regions that were uncovered. Typically, TWSs operating today work only on earthquake-induced tsunamis. TWSs estimate quickly earthquake location and size by real-time processing seismic signals; on the basis of some pre-defined "static" procedures (either based on decision matrices or on pre-archived tsunami simulations), assess the tsunami alert level on a large regional scale and issue specific bulletins to a pre-selected recipients audience. Not unfrequently these procedures result in generic alert messages with little value. What usually operative TWSs do not do, is to compute earthquake focal mechanism, to calculate the co-seismic sea-floor displacement, to assess the initial tsunami conditions, to input these data into tsunami simulation models and to compute tsunami propagation up to the threatened coastal districts. This series of steps is considered nowadays too time consuming to provide the required timely alert. An equivalent series of steps could start from the same premises (earthquake focal parameters) and reach the same result (tsunami height at target coastal areas) by replacing the intermediate steps of real-time tsunami simulations with proper selection from a large archive of pre-computed tsunami scenarios. The advantage of real-time simulations and of archived scenarios selection is that estimates are tailored to the specific occurring tsunami and alert can be more detailed (less generic) and appropriate for local needs. Both these procedures are still at an

    Asperger Autism is a lifelong psychiatric condition with highly circumscribed interests and routines, problems in social cognition, verbal and nonverbal communication, and also perceptual abnormalities with sensory hypersensitivity. To objectify both lower-level visual and cognitive alterations we looked for differences in visual event-related potentials (EEG) between Asperger observers and matched controls while they observed simple checkerboard stimuli. In a balanced oddball paradigm checkerboards of two checksizes (0.6° and 1.2°) were presented with different frequencies. Participants counted the occurrence times of the rare fine or rare coarse checkerboards in different experimental conditions. We focused on early visual ERP differences as a function of checkerboard size and the classical P3b ERP component as an indicator of cognitive processing. We found an early (100-200 ms after stimulus onset) occipital ERP effect of checkerboard size (dominant spatial frequency). This effect was weaker in the Asperger than in the control observers. Further a typical parietal/central oddball-P3b occurred at 500 ms with the rare checkerboards. The P3b showed a right-hemispheric lateralization, which was more prominent in Asperger than in control observers. The difference in the early occipital ERP effect between the two groups may be a physiological marker of differences in the processing of small visual details in Asperger observers compared to normal controls. The stronger lateralization of the P3b in Asperger observers may indicate a stronger involvement of the right-hemispheric network of bottom-up attention. The lateralization of the P3b signal might be a compensatory consequence of the compromised early checksize effect. Higher-level analytical information processing units may need to compensate for difficulties in low-level signal analysis.

    Many studies have attempted to define the relationship between postmenopausal osteoporosis and periodontal disease. Most studies support a positive association between these common diseases; however, many are cross-sectional in nature, include relatively small sample sizes, and have inadequate control of potential confounding factors, such as age, gender, hormone intake, race, and smoking, limiting our understanding of the nature of the relationship between these diseases. Clinical conditions causing low estrogen environments in postmenopausal women allow increased local production of the bone-active cytokine and the progression of periodontal disease. Prospective studies are needed to confirm or refute a causal relation.

  17. Bone turnover in postmenopausal osteoporosis

    Studies of the bone turnover in postmenopausal osteoporosis are essential, because the associated bone loss is inevitably due to the relative increase of bone resorption compared with bone formation. Measurement of the bone mineral content (BMC) in normal adults is assessed - partly on the uncorrected values and partly in proportion to the body muscle mass. The whole body retention (WBR) method is presented. The WBR and alternative urinary excretion (UE) methods used by the author are characterised and compared with the retention methods described in the literature. The representativity of WBR and UE for the estimation of bone turnover in normal subjects and patients with various bone metabolic diseases is discussed. The conclusion is that the modified retention methods used by the author have a satisfactory precision and accuracy in relation to the clinical studies carried out. The author's modification of the WBR method for determination of bone turnover and the alternative urinary excretion method (UE) consists in continuous scanning in the whole body count, using a gamma camera, and with the collimator a short distance from the volunteer. This procedure has the advantage of restricting the radioactive dose to 2 mCi (72 MBa). This is smaller by a factor of 5-10 than the dose used to measure WBR with equally simple counting equipment: With the author's procedure, using frontal counting, WBR is systematically underestimated by about 4 per cent point compared to the purely dorsal count, but since the frontal position is the most comfortable, requires a smaller radioactive dose, and the error is systematic, it is the preferred counting procedure. Correction of WBR and UE for bone mineral content is in principle a new parameter of bone turnover, whose improved accuracy increases the validity of the retention determinations. 136 refs. (EG)

    This study aims to present methods and baseline data from the Early versus Late Intervention Trial with Estradiol (ELITE), the only clinical trial designed to specifically test the timing hypothesis of postmenopausal hormone therapy (HT). The timing hypothesis posits that HT effects depend on the temporal initiation of HT relative to time since menopause. ELITE is a randomized, double-blind, placebo-controlled trial with a 2 × 2 factorial design. Six hundred forty-three healthy postmenopausal women without cardiovascular disease were randomized to oral estradiol or placebo for up to 6 to 7 years according to time since menopause (y). Carotid artery intima-media thickness (CIMT) and cardiac computed tomography were conducted to determine HT effects on subclinical atherosclerosis across menopause strata. Participants in the early and late postmenopausal strata were well-separated by mean age (55.4 vs 65.4 y) and median time since menopause (3.5 vs 14.3 y). Expected risk factors (age, blood pressure, and body mass index) were associated with CIMT at baseline in both strata. In the early postmenopausal group, but not in the late postmenopausal group, we observed significant associations between CIMT and factors that may play a role in the responsiveness of atherosclerosis progression according to timing of HT initiation. These include low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, sex hormone-binding globulin, and serum total estradiol. The ELITE randomized controlled trial is timely and unique. Baseline data indicate that ELITE is well-positioned to test the HT timing hypothesis in relation to atherosclerosis progression and coronary artery disease.

  20. Effects of Tibolone on the Breast of Postmenopausal Women

    Full Text Available For decades, hormone therapy (HT has been the mainstay for managing menopausal symptoms. However, the prolonged use of either single estrogen therapy (ET or a combination therapy of estrogen and progestogen (EPT might be associated with a slightly increased risk of breast cancer. Alternative therapies that are effective in the prevention and/or treatment of menopause, having associated morbidities but no unwanted effects, are of primary interest in clinical practice. Tibolone (Livial; NV Organon, Oss, The Netherlands is structurally related to 19-nortestosterone derivatives and is a new postmenopausal regimen with a unique pharmacological profile, licensed for the relief of climacteric symptoms and the prevention of osteoporosis in postmenopausal women. Tibolone exhibits weak estrogenic, progestogenic, and androgenic activities, which in theory might influence the breast. The effect of tibolone on breast tissue, however, is obscure. The purpose of this study was to assess the effects of tibolone on breast safety, and the collected data include preclinical models, clinical observation, and epidemiologic study. Although in vitro studies showed conflicting results (with the majority being favorable effects regarding the effects of tibolone on breast cells, in vivo studies showed favorable effects of tibolone on the breast in animal models. Similarly, an epidemiologic study indicated an increased risk of breast cancer when tibolone was used to manage climacteric symptoms of postmenopausal women, but accumulated data obtained from radiologic studies (mammography showed a possible protective effect of tibolone on the breast. Taken together, we conclude that tibolone, if not superior to conventional HT, may be more acceptable to clinicians as a therapeutic drug option for use with symptomatic menopausal women. Only time will tell whether tibolone will be the preferred option.

Cervicovaginal smear results of 894 postmenopausal women were evaluated retrospectively according to the 2001 Bethesda system (BS in Adana Numune Training and Research Hospital of Obstetrics and Gynecology Clinic from 2007–2010. The study found, normal results on 287 patients (32.1%, benign findings on 556 patients (62.2%, abnormal epithelial cell changes on 48 patients (5.36% and malignant changes on 3 patients (0.33%. The abnormal epithelial changes were observed to be atypical cells of undetermined significance (ASC-US for 22 patients (2.46%, low-grade squamous intraepithelial lesion (LSIL for 11 patients (1.23%, high-grade squamous intraepithelial lesion(HSIL for 7 patients (0.78%, findings that cannot exclude a high-grade squamous intraepithelial lesion (ASC-H for 6 patients (0.55% and atypical glandular cells-not otherwise specified (AGC-NOS for 2 patients (0.22%. Malignant results were 2 squamous cell carcinomas (SCC (0.22% and 1 adenocarcinoma (ACC (0.11%. Cervical cancer screening programs should be expanded and Pap smear screening should be applied to all postmenopausal women. The longer time span involved from premalignant lesions to cancer improves our chance for the diagnosis and treatment. As the incidence of invasive cancer increases in menopausal period, gynecological smear examination and regular check-up are crucial. A high rate of abnormalities of epithelial cells was detected in this study.

Methods: This is a 16-week, randomized, parallel, open-label, controlled trial in a menopausal clinic in a tertiary health care center in Northeastern Thailand. The intervention group received a 60-minute session of MR training and were encouraged to practice 15–20 minutes a day, at least 5 days a week. The control group received lifestyle education, including diet and exercise. The primary and secondary outcomes were systolic and diastolic blood pressure (SBP and DBP. Results: Of 432 participants, 215 and 217 were randomly allocated to the MR and control groups, respectively. Of those, 167 participants in the MR group and 175 participants in the control group completed the study. The SBP was significantly more reduced in the MR group, with a mean of 2.1 mmHg (P < 0.001. There was no significant difference between groups on the changed DBP. Conclusion: The MR technique may be effective in lowering SBP in Thai postmenopausal women visiting a menopause clinic. Its efficacy may be observed as soon as 4 weeks after start of treatment. Long-term and combined relaxation therapy and antihypertensive agents are warranted in a large cohort of this population.

    To examine whether physical activity during the last five years is related to later breast mammographic density in postmenopausal Greek women. We designed a cross-sectional study in 724 women, of ages 45-67 years. An interview-administered questionnaire was used to obtain information on duration and intensity of recreational physical activity during five years preceding study recruitment. Mammograms were evaluated according to BIRADS classification and BIRADS score was also estimated. Multivariate ordinal logistic regression analysis was used to assess associations between physical activity index and breast density according to the BIRADS classification methods. We observed a statistically significant inverse association of mammographic breast density measured by the BIRADS classification method and recreational exercise (OR=-0.10; 95% CI -0.018, -0.001; p=0.022). For one unit increase in physical activity as expressed by the MET-h/week score, the odds of lower versus higher breast density categories are 1.105 greater, given that all of the other variables in the model are held constant. A modifying effect by age at recruitment was evident among participants, with a stronger inverse association between recreational activity and mammographic breast density among older women (OR=-0.036; 95% CI -0.063, -0.009; p=0.009). An inverse association between physical activity and BIRADS score was evident, not reaching statistical significance (OR=0.00; 95% CI -0.009, 0.008; p=0.887). Mammographic breast area was lower in postmenopausal women who participated in sports/recreational physical activity compared to inactive controls. Increasing physical activity levels among postmenopausal women might be a reasonable approach to reduce mammographic density. However, until more physical activity and mammographic breast density studies are conducted that confirm our findings, they have to be interpreted with caution, due to the retrospective nature of our data and the possibility of

    We present multi-wavelength observations of the hyper-energetic gamma-ray burst (GRB) 130907A, a Swift-discovered burst with early radio observations starting at ≈4 hr after the γ-ray trigger. GRB 130907A was also detected by the Fermi/LAT instrument and at late times showed a strong spectral evolution in X-rays. We focus on the early-time radio observations, especially at >10 GHz, to attempt to identify reverse shock signatures. While our radio follow-up of GRB 130907A ranks among the earliest observations of a GRB with the Karl G. Jansky Very Large Array, we did not see an unambiguous signature of a reverse shock. While a model with both reverse and forward shock can correctly describe the observations, the data is not constraining enough to decide upon the presence of the reverse-shock component. We model the broadband data using a simple forward-shock synchrotron scenario with a transition from a wind environment to a constant density interstellar medium (ISM) in order to account for the observed features. Within the confines of this model, we also derive the underlying physical parameters of the fireball, which are within typical ranges except for the wind density parameter (A * ), which is higher than those for bursts with wind-ISM transition, but typical for the general population of bursts. We note the importance of early-time radio observations of the afterglow (and of well-sampled light curves) for unambiguously identifying the potential contribution of the reverse shock

    Objective Constipation and soiling are common in childhood. This study examines the comorbidity between childhood constipation and soiling and early childhood risk factors for these problems. Design The sample comprised 8435 participants from the Avon Longitudinal Study of Parents and Children with maternally reported measures of constipation (six time points between 4 and 10 years) and soiling (five time points between 4 and 9 years). We used latent class analysis to extract longitudinal patterns of constipation and soiling. We examined whether the latent classes are differentially associated with maternally reported risk factors in early childhood (stool consistency, breast feeding, socioeconomic background, gestation, birth weight, developmental level and age at initiation of toilet training) using multinomial logistic regression models. Results We extracted four latent classes: ‘normative’ (74.5%: very low probability of constipation or soiling), ‘constipation alone’ (13.2%), ‘soiling alone’ (7.5%) and ‘constipation with soiling’ (4.8%). Hard stools at 2½ years were associated with increased odds of constipation alone. Developmental delay at 18 months was associated soiling alone and constipation with soiling, but not constipation alone. We found limited evidence of associations with socioeconomic background and no evidence of associations with age at initiation of toilet training, breast feeding, gestational age or birth weight. Conclusion Constipation alone was the most prevalent pattern in this cohort. Treatment for hard stools in early childhood is needed to prevent chronic constipation at school age. Constipation with soiling was less common than soiling alone. Further research is needed into the causes of non-retentive soiling. PMID:29637194

    The incidence of heart failure in type 2 diabetes is high and it has poorer prognosis when compared with patients without diabetes. Access to echocardiography is limited and alternative methods to identify early heart failure such as the measurement of natriuretic peptides levels have been proposed. However, their wide biological variation could limit their clinical utility. Our aim was to determine if the intrinsic biological variation of one of these peptides, N-terminal proBNP, is as wide in type 2 diabetes as it is in health and to calculate the critical difference values that could be utilised in clinical practice to ensure changes observed between two samples are due to intervention rather than to its biological variability. 12 postmenopausal women with diet controlled type 2 diabetes and without heart failure were compared with 11 control postmenopausal women without diabetes. N-terminal proBNP levels were measured on 10 occasions. The biological variation was calculated according to Fraser's methods. The mean NT-proBNP level was similar in both groups (mean ± standard deviation; type 2 diabetes, 10.7 pmol/L± 8.5 versus 8.49±6.0 pmol/L, p = 0.42). The biological variation was also similarly wide. The critical difference in patients with type 2 diabetes was between -70% and ±236%. Type 2 diabetes does not appear to significantly influence the marked biological variation of N-terminal proBNP in postmenopausal women. The critical difference values reported in this study could be used to titrate therapy or monitor response to interventions although the change required in between samples is wide and this might limit its utility.

    To study endometrial histopathology in women presenting with postmenopausal bleeding. A two-year study from January 2003 to December 2004 of 100 cases of postmenopausal bleeding was conducted at Combined Military Hospital, Sialkot. The histopathology of endometrial biopsy specimens was done to find out the causes of postmenopausal bleeding in these ladies. All these 100 patients had confirmed menopause and the average age was 55 years and above. The most common histopathological diagnosis was senile endometrial atrophy (27%), followed by simple cystic hyperplasia in (17%). Three cases of simple cystic hyperplasia had coexistent ovarian tumors. Glandular hyperplasia without atypia was seen in 6% and with atypia in 4%. Other causes were endometritis (13%), endometrial polyps (8%), proliferative phase endometrium (6%) and secretary phase endometrium (5%). Endometrial carcinoma was seen in (6%) cases, (8%) biopsy specimens were non-representative. Although senile endometrial atrophy was most commonly found in these ladies but a significant percentage of endometrial hyperplasia and endometrial cancer implies the need for investigating all cases of postmenopausal bleeding. Bimanual examination and pelvic ultrasonography should be combined with endometrial sampling so that rare pelvic pathologies may not be missed. (author)

    We observe an extraordinary link in the Crab pulsar between the enhancement of an optical pulse and the timing of the corresponding giant radio pulse. At optical through infrared wavelengths, our observations use the high time resolution of ARray Camera for Optical to Near-IR Spectrophotometry, a unique superconducting energy-resolving photon-counting array at the Palomar 200 inch telescope. At radio wavelengths, we observe with the Robert C. Byrd Green Bank Telescope and the Green Bank Ultimate Pulsar Processing Instrument backend. We see an 11.3% ± 2.5% increase in peak optical flux for pulses that have an accompanying giant radio pulse arriving near the peak of the optical main pulse, in contrast to a 3.2% ± 0.5% increase when an accompanying giant radio pulse arrives soon after the optical peak. We also observe that the peak of the optical main pulse is 2.8% ± 0.8% enhanced when there is a giant radio pulse accompanying the optical interpulse. We observe no statistically significant spectral differences between optical pulses accompanied by and not accompanied by giant radio pulses. Our results extend previous observations of optical-radio correlation to the time and spectral domains. Our refined temporal correlation suggests that optical and radio emission are indeed causally linked, and the lack of spectral differences suggests that the same mechanism is responsible for all optical emission.

    Osteoporosis is particularly high in females, the early identification of which remains a challenge. Panoramic radiographs are routinely advised to detect periodontal diseases and can be used to predict low bone mineral density (BMD). Hence, this investigation was aimed to identify the risk of osteoporosis in pre- and postmenopausal periodontally healthy and chronic periodontitis women with digital panoramic radiographs. The study population consisted of 120 patients equally divided as Group I - Premenopausal periodontally healthy, Group II - Premenopausal periodontitis, Group III - Postmenopausal periodontally healthy, and Group IV - Postmenopausal periodontitis. Clinical parameters were recorded, and digital panoramic radiographs were used to record the mental index (MI), panoramic mandibular index (PMI), and mandibular cortical index (MCI) scores. MI was found to be varied, and the differences were highly significant among Group III and IV ( P = 0.0003) and Group II and IV ( P = 0.0007), and significant difference was found between Group I and Group II ( P = 0.0113). MCI evaluation showed a greater prevalence of C2 and C3 patterns among postmenopausal women. MCI correlation with MI ( P periodontitis in postmenopausal women confirms the high risk of osteoporosis in them. Furthermore, an increased percentage of patients with undetected decrease in BMD may be identified by screening with digital panoramic radiographs which are done on a routine basis for periodontal and other dental diseases and thus could be used as an effective aid to quantify bone density in future.

    To date, there is no consensus on the utility of screening procedures for the early detection of endometrial cancer. The value of transvaginal ultrasound for screening of asymptomatic endometrial cancer has been discussed controversially. This study was conducted to evaluate whether asymptomatic patients with endometrial cancer have a better prognosis than symptomatic patients with endometrial cancer diagnosed after postmenopausal bleeding. In the present multi-center study, the effect of the presence of postmenopausal bleeding on prognosis was evaluated retrospectively in 605 patients with endometrial cancer using patients' files. 543 patients (133 patients were asymptomatic, 410 patients were symptomatic) with endometrioid endometrial cancer were enrolled in all further analysis. Student's t-test, Cox regression analysis and Kaplan-Meier analysis were used were appropriate. Presence/absence of a postmenopausal bleeding was not associated with tumor stage (p = 0.2) and age at diagnosis (p = 0.5). Asymptomatic patients with endometrial cancer had a significantly higher rate of well and moderate-differentiated tumors compared to symptomatic patients (p = 0.008). In univariable and multivariable survival analysis, tumor stage, tumor grade, and patients' age at diagnosis, but not presence/absence of a postmenopausal bleeding, were associated with disease free and overall survival. Asymptomatic patients with endometrial cancer have a higher rate of well differentiated tumors compared to patients with a postmenopausal bleeding prior to diagnosis. The prognosis of both groups of patients was similar

    Both Geomorphological and mineralogical evidence point to the episodic availability of liquid water on the surface of early Mars. However, the distribution of water was not uniform over space and time. Considerable environmental and climate variations due to latitudinal or elevation effects combined with a diverse surface geology caused distinctively different of local conditions that influenced the planet`s water content. The history of water on Mars has been constantly revised and refined during the past years. Landforms such as widespread valley networks, fluvial deposits and associated assemblages of hydrated clay minerals support the hypothesis that the Martian climate was to some extend warm and wet during the early history of Mars [e.g.,1,2]. At the boundary between the Late Noachian and the Early Hesperian, environmental and climate conditions changed significantly and resulted in a transition towards a colder and dryer climate. The intensity of aqueous activity decreased throughout the Hesperian, including a transition from long-term and repeated precipitation-induced fluvial activity towards reduced, short-term, spatially isolated and groundwater-dominated fluvial erosion [e.g.,3,4,5,6]. At the end of the Hesperian, fluvial erosion has mostly ceased and volcanic, aeolian and glacial processes are interpreted to be dominant on Mars. The Early Amazonian was characterized most likely by a cold and dry climate that was similar to the conditions on recent Mars. However, Mars' climate and aqueous history, in particular the timing of the termination of fluvial activity and the transition from precipitation-induced toward groundwater-dominated erosion as well as the temperature with time, is still subject to debate. Modeling of flow transport processes revealed that the formation of deltas on Mars geologically requires only brief timespans [7] and, based on discharge estimates, the formation of erosional valleys also needs less than a few million years and seems

    Although weight loss following laparoscopic sleeve gastrectomy (LSG) can be substantial, weight recidivism is still a major concern. The aim of our work is to study early weight recidivism following LSG and to evaluate the role of gastric computed tomography volumetry (GCTV) in the assessment of patients experiencing early weight regain. One-hundred and one morbidly obese patients undergoing LSG were prospectively studied. Patients were followed up for 2 years. Those who presented with weight recidivism were counseled for dietary habits and assessed for the amount of weight regain. Patients who regained weight were scheduled for GCTV. Twelve patients were excluded from the study. Weight recidivism was reported in 9/89 patients (10.1 %) [weight loss failure (n = 1), weight regain (n = 8)] and was almost always first recognized 1½-2 years after LSG. The amount of weight regain showed negative correlations with preoperative body weight and body mass index (r = -0.643, P = 0.086 and r = -0.690, P = 0.058; respectively) and positive correlations with the distance between the pylorus and the beginning of the staple line (r = 0.869, P = 0.005), as well as with the residual gastric volume (RGV) on GCTV 2 years after LSG (r = 0.786, P = 0.021). In the small group of patients who regained weight, a longer distance between the pylorus and the beginning of the staple line, as well as a higher RGV on GCTV 2 years after LSG, were both associated with increased weight regain. Gastric computed tomography volumetry with RGV measurement holds promise as a useful research tool after LSG.

    In foraminifera, so-called “double tests” usually arise due to abnormal growth originating mainly from twinning, but may also be caused by irregularities in the early chambers and by regeneration after test injury that modifies the direction of growth. A fourth cause of double tests has only rarely been reported: the fusion of the tests of two adult individuals. We studied an early Eocene Nummulites double test consisting of two adult individuals that fused after an extended period of independent growth. The specimen was studied using computed tomography with micrometric resolution (micro-CT) that allowed bi- and three-dimensional visualization of the internal structure. Before fusion each individual test had 30–36 chambers, which, by comparison with growth rates in recent nummulitids, implies at least three months of independent growth. After fusion, the compound test grew in two spirals that fused after about one whorl and then continued in a single spiral. To fuse their tests, either adult individuals have to be forced to do so or the allorecognition (ability to distinguish between self and another individual) mechanisms must fail. A possible explanation for the merged Nummulites tests in this study is forced fusion in attached individuals after surviving ingestion and digestion by a metazoan. Alternatively, environmental stress could lead to a failure of allorecognition mechanisms and/or foraminiferal motility. Once fused, subsequent growth seems to be determined mainly by the relative orientation of individual tests. In any case, the frequency in which adult fusion occurs remains unknown. PMID:26166916

    This study quantifies mean annual and monthly fluxes of Earth's water cycle over continents and ocean basins during the first decade of the millennium. To the extent possible, the flux estimates are based on satellite measurements first and data-integrating models second. A careful accounting of uncertainty in the estimates is included. It is applied within a routine that enforces multiple water and energy budget constraints simultaneously in a variational framework in order to produce objectively determined optimized flux estimates. In the majority of cases, the observed annual surface and atmospheric water budgets over the continents and oceans close with much less than 10% residual. Observed residuals and optimized uncertainty estimates are considerably larger for monthly surface and atmospheric water budget closure, often nearing or exceeding 20% in North America, Eurasia, Australia and neighboring islands, and the Arctic and South Atlantic Oceans. The residuals in South America and Africa tend to be smaller, possibly because cold land processes are negligible. Fluxes were poorly observed over the Arctic Ocean, certain seas, Antarctica, and the Australasian and Indonesian islands, leading to reliance on atmospheric analysis estimates. Many of the satellite systems that contributed data have been or will soon be lost or replaced. Models that integrate ground-based and remote observations will be critical for ameliorating gaps and discontinuities in the data records caused by these transitions. Continued development of such models is essential for maximizing the value of the observations. Next-generation observing systems are the best hope for significantly improving global water budget accounting.

    This work covers Ultraviolet Imaging Telescope (UIT) observations of early-type galaxies (155 nm) and Far Ultraviolet Spectroscopic Explorer (FUSE) spectra of a Galactic subdwarf B star (sdB). Early UV space astronomy missions revealed that early-type galaxies harbor a population of stars with effective temperatures greater than that of the main sequence turn-off (about 6,000 K) and UV emission that is very sensitive to characteristics of the stellar population. We present UV (155 nm) surface photometry and UV-B color profiles for 8 E and SO galaxies observed by UIT. Some objects have de Vaucouleurs surface brightness profiles, while others have disk-like profiles, but we find no other evidence for the presence of a disk or young, massive stars. There is a wide range of UV-B color gradients, but there is no correlation with metallicity gradients. SdB stars are the leading candidate UV emitters in old, high metallicity stellar populations (e.g., early-type galaxies). We observed the Galactic sdB star PG0749+658 with FUSE and derived abundances with the aim of constraining models of the heavy element distribution in sdB atmospheres.

    Full Text Available Extant paper records of the early analog seismic network of Taiwan represent a large resource for earthquake studies in several disciplines. In this study, we report on T waves generated from offshore earthquakes, based on analog observations. The T phases were identified from their stable apparent velocity of about 1.5 km s-1 and other observations using data recorded by stations in eastern Taiwan and on two nearby islands. The observed T phases are recorded for the first time from Taiwan, and in particular are observed by the network in the distal range of local earthquakes. Most of the T waves are observed at island stations at epicentral distances greater than 100 km. For earthquakes that occurred a great distance east of Taiwan, the T phases are always the most dominant phases observed at island stations east of Taiwan, and are also seen at some inland stations with smaller amplitudes. No T phases from inland events were observed by stations on Taiwan or on nearby islands. The observations indicate that the amplitude of the T phase is highly attenuated on its land path and that the propagation direction of the T phase is affected by water depth.

    The increased medicalization of different life stages, including menopause, is a subject studied mostly in the Western context. Examining medicalization in the non-Western world advances discussions of body, identity and health. In this paper, I analyze the discourses around postmenopausal osteoporosis in Turkey, focusing on the different constructions of risk in the medical and popular literature. The empirical basis of the paper draws on ethnographic research done in Istanbul, Turkey between June 2006 and March 2007. The research includes participant observation in gynecology clinics, interviews with clinicians and menopausal women and archival research on the representations of menopause in the Turkish media between 1999 and 2006. Referred to as kemik erimesi (melting of the bones) in colloquial Turkish, osteoporosis has been an essential component in the medicalization of menopause in Turkey. I argue that postmenopausal osteoporosis is defined as a combination of embodied risk, which is related to the definition of menopause as a risky period, and lifestyle risk, demonstrated in discussions around "traditional" vs. "modern" clothing and healthcare habits. The Turkish example emphasizes the importance of local conditions in defining medical risk and complicates the embodied vs. lifestyle risk categories. Copyright © 2011 Elsevier Ltd.

    Being overweight or obese increases the risk of postmenopausal breast cancer. A potential reason may be the frequently observed positive association of BMI with endogenous sex hormones and its negative association with sex hormone-binding globulin (SHBG). The purpose of this study was to investigate whether a woman's body fat distribution shows a BMI-independent association with these breast cancer-related biomarkers. Performing cross-sectional analyses among 1,180 postmenopausal women, we assessed whether associations of surrogates for an abdominal (waist circumference; waist-to-hip ratio, WHR) and gluteofemoral (hip circumference) fat distribution with estrone, total and free estradiol, androstenedione, total and free testosterone, and SHBG changed after adjustment for, or stratification by, BMI. All anthropometric measures were positively associated with estrogens and free testosterone, and negatively with SHBG. After adjustment for BMI, associations of free estradiol, free testosterone, and SHBG with both waist circumference and WHR remained significant, but all initially significant associations with hip circumference were abolished. In stratified analyses, waist circumference and WHR correlated with free estradiol, free testosterone, and SHBG in women with a BMI fat on these biomarkers may be masked by the already large amount of overall body fat. On the whole, our results indicate that waist circumference and WHR, but not hip circumference, are associated with SHBG and SHBG-related sex hormones (free estradiol and free testosterone) independently of BMI.

  18. Ionospheric detection of tsunami earthquakes: observation, modeling and ideas for future early warning

    Detection of ionospheric anomalies following the Sumatra and Tohoku earthquakes (e.g., Occhipinti 2015) demonstrated that ionosphere is sensitive to earthquake and tsunami propagation: ground and oceanic vertical displacement induces acoustic-gravity waves propagating within the neutral atmosphere and detectable in the ionosphere. Observations supported by modelling proved that ionospheric anomalies related to tsunamis are deterministic and reproducible by numerical modeling via the ocean/neutral-atmosphere/ionosphere coupling mechanism (Occhipinti et al., 2008). To prove that the tsunami signature in the ionosphere is routinely detected we show here perturbations of total electron content (TEC) measured by GPS and following tsunamigenic earthquakes from 2004 to 2011 (Rolland et al. 2010, Occhipinti et al., 2013), nominally, Sumatra (26 December, 2004 and 12 September, 2007), Chile (14 November, 2007), Samoa (29 September, 2009) and the recent Tohoku-Oki (11 Mars, 2011). Based on the observations close to the epicenter, mainly performed by GPS networks located in Sumatra, Chile and Japan, we highlight the TEC perturbation observed within the first 8 min after the seismic rupture. This perturbation contains information about the ground displacement, as well as the consequent sea surface displacement resulting in the tsunami. In addition to GNSS-TEC observations close to the epicenter, new exciting measurements in the far-field were performed by airglow measurement in Hawaii show the propagation of the internal gravity waves induced by the Tohoku tsunami (Occhipinti et al., 2011). This revolutionary imaging technique is today supported by two new observations of moderate tsunamis: Queen Charlotte (M: 7.7, 27 October, 2013) and Chile (M: 8.2, 16 September 2015). We finally detail here our recent work (Manta et al., 2017) on the case of tsunami alert failure following the Mw7.8 Mentawai event (25 October, 2010), and its twin tsunami alert response following the Mw7

  19. Integrating observation and statistical forecasts over sub-Saharan Africa to support Famine Early Warning

    Famine early warning in Africa presents unique challenges and rewards. Hydrologic extremes must be tracked and anticipated over complex and changing climate regimes. The successful anticipation and interpretation of hydrologic shocks can initiate effective government response, saving lives and softening the impacts of droughts and floods. While both monitoring and forecast technologies continue to advance, discontinuities between monitoring and forecast systems inhibit effective decision making. Monitoring systems typically rely on high resolution satellite remote-sensed normalized difference vegetation index (NDVI) and rainfall imagery. Forecast systems provide information on a variety of scales and formats. Non-meteorologists are often unable or unwilling to connect the dots between these disparate sources of information. To mitigate these problem researchers at UCSB's Climate Hazard Group, NASA GIMMS and USGS/EROS are implementing a NASA-funded integrated decision support system that combines the monitoring of precipitation and NDVI with statistical one-to-three month forecasts. We present the monitoring/forecast system, assess its accuracy, and demonstrate its application in food insecure sub-Saharan Africa.

    Few studies have evaluated the separate contributions of maltreatment and ongoing quality of parent-child interaction to the etiology of antisocial personality features using a prospective longitudinal design. 120 low-income young adults (aged 18-23) were assessed for extent of ASPD features on the Structured Clinical Interview for Diagnosis-Axis II, for presence of maltreatment on the Conflict Tactics Scale, Traumatic Experiences Scale, and Adult Attachment Interview, and for referral in infancy to parent-infant clinical services. Fifty-six of these families had been studied longitudinally since the first year of life. In infancy, attachment disorganization and disrupted mother-infant interaction were assessed; in middle childhood, disorganized-controlling attachment behaviors were reliably rated. In kindergarten and second grade, behavior problems were assessed by teacher report. In cross-sectional analyses, maltreatment was significantly associated with ASPD features but did not account for the independent effect of early referral to parent-infant services on ASPD features. In longitudinal analyses, maternal withdrawal in infancy predicted the extent of ASPD features twenty years later, independently of childhood abuse. In middle childhood, disorganized attachment behavior and maladaptive behavior at school added to prediction of later ASPD features. Antisocial features in young adulthood have precursors in the minute-to-minute process of parent-child interaction beginning in infancy.

  1. Early Fermi Gamma-ray Space Telescope Observations of the Quasar 3C454.3

    Energy Technology Data Exchange (ETDEWEB)

    Abdo, A

    2009-05-07

    This is the first report of Fermi Gamma-ray Space Telescope observations of the quasar 3C 454.3, which has been undergoing pronounced long-term outbursts since 2000. The data from the Large Area Telescope (LAT), covering 2008 July 7-October 6, indicate strong, highly variable {gamma}-ray emission with an average flux of {approx} 3 x 10{sup -6} photons cm{sup -2} s{sup -1}, for energies > 100 MeV. The {gamma}-ray flux is variable, with strong, distinct, symmetrically-shaped flares for which the flux increases by a factor of several on a time scale of about three days. This variability indicates a compact emission region, and the requirement that the source is optically thin to pair-production implies relativistic beaming with Doppler factor {delta} > 8, consistent with the values inferred from VLBI observations of superluminal expansion ({delta} {approx} 25). The observed {gamma}-ray spectrum is not consistent with a simple power-law, but instead steepens strongly above {approx} 2 GeV, and is well described by a broken power-law with photon indices of {approx} 2.3 and {approx} 3.5 below and above the break, respectively. This is the first direct observation of a break in the spectrum of a high luminosity blazar above 100 MeV, and it is likely direct evidence for an intrinsic break in the energy distribution of the radiating particles. Alternatively, the spectral softening above 2GeV could be due to -ray absorption via photonphoton pair production on the soft X-ray photon field of the host AGN, but such an interpretation would require the dissipation region to be located very close ({approx}< 100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

    Delirium in critically ill children is a severe neuropsychiatric disorder which has gained increased attention from clinicians. Early identification of delirium is essential for successful management. The Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale was developed to detect Paediatric Delirium (PD) at an early stage. The aim of this study was to determine the measurement properties of the PD component of the SOS-PD scale in critically ill children. A prospective, observational study was performed in patients aged 3 months or older and admitted for more than 48h. These patients were assessed with the SOS-PD scale three times a day. If the SOS-PD total score was 4 or higher in two consecutive observations, the child psychiatrist was consulted to assess the diagnosis of PD using the Diagnostic and Statistical Manual-IV criteria as the "gold standard". The child psychiatrist was blinded to outcomes of the SOS-PD. The interrater reliability of the SOS-PD between the care-giving nurse and a researcher was calculated with the intraclass correlation coefficient (ICC). A total of 2088 assessments were performed in 146 children (median age 49 months; IQR 13-140). The ICC of 16 paired nurse-researcher observations was 0.90 (95% CI 0.70-0.96). We compared 63 diagnoses of the child psychiatrist versus SOS-PD assessments in 14 patients, in 13 of whom the diagnosis of PD was confirmed. The sensitivity was 96.8% (95% CI 80.4-99.5%) and the specificity was 92.0% (95% CI 59.7-98.9%). The SOS-PD scale shows promising validity for early screening of PD. Further evidence should be obtained from an international multicentre study. Copyright © 2017 Australian College of Critical Care Nurses Ltd. Published by Elsevier Ltd. All rights reserved.

  3. Recent increases in trifluoromethane (HFC-23) global emissions and early atmospheric changes observed for other hydrofluorocarbons

    Trifluoromethane (HFC-23) is an unintended by-product of chlorodifluoromethane (HCFC-22) production and has a 100-yr global warming potential of 14,800. Firn-air and ambient air measurements of HFC-23 from three firn sampling excursions to Antarctica between 2001 and 2009 are used to construct a consistent atmospheric history for this chemical in the Southern Hemisphere. The results show continued increases in the atmospheric abundance of HFC-23 and imply substantial increases in HFC-23 global emissions since 2003. These emission increases are coincident with rapidly increasing HCFC-22 production in developing countries and are observed despite efforts in recent years to limit emissions of HFC-23 through the Kyoto Protocol’s Clean Development Mechanism. These results will be considered along with new observations of additional HFCs from archived air, firn air, and ongoing flask-air measurements. Considered together, atmospheric increases observed for hydrochlorofluorocarbons and hydrofluorocarbons accounted for ~9% of the increase in total direct radiative forcing from anthropogenic gases during 2003-2008, an addition that was slightly larger than attributable to N2O over this same period.

    Previous studies have demonstrated that abnormal physiological observations are often recorded on patients' observation charts but not acted on, with ensuing negative consequences. To address this issue within our hospital, traditional charts with a graphic depiction of observations were replaced with new charts combining early warning scores (EWS) with numerically depicted observations. However, the replacement did not include a graphic display of observations in the form of trend graphs. The present study compared the speed and accuracy of data interpretation between the 2 charts. Six clinical scenarios (low-grade temperature, spiking temperature, tachypnea, Cushing's response, hypovolaemic shock and normal observations) were identically depicted on old and new charts, creating 12 charts. One hundred health-care professionals were asked to study each of the charts, and the time taken to give a diagnosis was recorded. Time taken and accuracy of response were compared between the 2 charts. The old chart was associated with faster responses in all of the scenarios, reaching statistical significance in 5 of the 6 scenarios (P Graphic display of data is associated with faster and more accurate assimilation of information. Hence, charts combining EWS with graphic portrayal of observation trends may contribute to earlier recognition of sick patients.

    To investigate the effect of intranasal estrogen replacement therapy administered to postmenopausal women alone or in combination with progesterone on markers of cardiovascular risk. The study was conducted with 44 voluntary postmenopausal women. In group I (n = 15), the patients were treated with only intranasal estradiol (300 μg/day estradiol hemihydrate). In group II (n = 11), the patients received cyclic progesterone (200 mg/day micronized progesterone) for 12 days in each cycle in addition to continuous intranasal estradiol. Group III (n = 18) was the controls. Serum lipid profiles, oxidised low-density lipoprotein (LDL) and other markers of cardiovascular risk were assessed at baseline and at the 3rd month of the treatment. Lipid profile, LDL apolipoprotein B, lipoprotein a, homocysteine, oxidised LDL values and oxidised LDL/LDL cholesterol ratio were not observed to change after 3 months compared to baseline values within each group (p > 0.016). In comparison to changes between the groups after the treatment, only oxidised LDL levels and oxidised LDL/LDL cholesterol ratios of group II were increased compared to control group (p < 0.05). Intranasal estradiol alone did not appear to have an effect on markers of cardiovascular risk in healthy postmenopausal women. However, the addition of cyclic oral micronized progesterone to intranasal estradiol influenced the markers of cardiovascular risk negatively in comparison to non-users in healthy postmenopausal women.

    Wnt signaling plays an important role in the bone development and remodeling. The Wnt antagonist Dkk-1 is a potent inhibitor of bone formation. The aims of this study were firstly to compare the serum Dkk-1 levels in postmenopausal osteoporosis patients with age-matched healthy controls, and secondly, to assess the possible relationship between Dkk-1 and β-catenin, sclerostin, or bone turnover markers [CTX, PINP, N-MID-OT and 25(OH)D] in the setting of postmenopausal osteoporosis. A total of 350 patients with postmenopausal osteoporosis and 150 age-matched healthy controls were enrolled, and the serum levels of Dkk-1, β-catenin, sclerostin, OPG, and RANKL were detected by ELISA, and bone turnover markers [CTX, PINP, N-MID-OT and 25(OH)D] were measured by Roche electrochemiluminescence system in two groups. Serum Dkk-1 levels were significantly higher in postmenopausal osteoporosis group than in control group (Posteoporosis group. No similar correlations ware observed in control group. The results provided evidence for the role of Dkk-1 in bone metabolism and demonstrated the link of Dkk-1 and Wnt/β-catenin in some ways.

    Menopause is a natural step in the process of aging. Postmenopausal women have decreased levels of antioxidants and increased oxidative stress, the latter of which plays an important role in atherogenesis. The aim of the present study was to evaluate the relationship of the body mass index (BMI) with serum catalase activity, malondialdehyde (MDA), and dehydroepiandrosterone sulfate (DHEAS) levels in healthy postmenopausal women and estimate whether the MDA/DHEAS ratio is a possible marker of oxidative stress for determining cardiovascular risk in these women. We investigated serum catalase activity, MDA, and DHEAS levels, parity history, age, and BMI in 96 healthy postmenopausal women aged 50-82 years. The serum MDA levels and catalase activity were measured spectrophotometrically. The serum DHEAS levels were measured using an enzyme-linked immunosorbent assay. The ratio percentage of the serum DHEAS levels to serum MDA levels was designated as a biomarker for oxidative stress. The mean BMI of the patients was 31.72 ± 6.16 kg/m(2) (range = 20.5-47.94). The MDA/DHEAS ratio was significantly decreased in patients with a BMI over 30 compared to that of patients with a BMI between 25 and 30 (P = 0.025). Moreover, BMI was positively correlated with serum DHEAS levels (r = 0.285, P < 0.01) and negatively correlated with the MDA/DHEAS ratio (r = -0.241, P < 0.05) in postmenopausal women. Furthermore, BMI was observed to be a potential predictor of the MDA/DHEAS ratio based on covariance analysis (P = 0.039). Our results indicate that healthy, obese, postmenopausal women have a decreased MDA/DHEAS ratio. Additionally, BMI was observed to be a potential predictor of the MDA/DHEAS ratio.

  8. White noise from dark matter: 21 cm observations of early baryon collapse

    In concordance cosmology, dark matter density perturbations generated by inflation lead to nonlinear, virialized minihalos, into which baryons collapse at redshift z∼20. We survey here novel baryon evolution produced by a modification of the power spectrum from white noise density perturbations at scales below k∼10h Mpc -1 (the smallest scales currently measured with the Lyman-α forest). Exotic dark matter dynamics, such as would arise from scalar dark matter with a late phase transition (similar to an axion, but with lower mass), or primordial black hole dark matter, create such an amplification of small scale power. The dark matter produced in such a phase transition collapses into minihalos, with a size given by the dark matter mass within the horizon at the phase transition. If the mass of the initial minihalos is larger than ∼10 -3 M · , the modified power spectrum is found to cause widespread baryon collapse earlier than standard ΛCDM, leading to earlier gas heating. It also results in higher spin temperature of the baryons in the 21 cm line relative to ΛCDM at redshifts z>20 if the mass of the minihalo is larger than 1M · . It is estimated that experiments probing 21 cm radiation at high redshift will contribute a significant constraint on dark matter models of this type for initial minihalos larger than ∼10M · . These experiments may also detect (or rule out) primordial black holes as the dark matter in the window 30M · H 3 M · still left open by strong microlensing experiments and other astrophysical constraints. Early experiments reaching to z≅15 will constrain minihalos down to ∼10 3 M ·

    To search for a better therapy for early postoperative inflammatory small bowel obstruction (EPISBO). Two hundred and forty cases were divided into four groups according to admitting order, 60 cases in each group. Routine treatments in western medicine were used in group A including gastrointestinal decompression, parenteral nutrition, anti-infection, supportive therapy and so on. Group B was treated with electroacupuncture in Zusanli (ST 36), Shangjuxu (ST 37) etc. in addition to those given in group A. Group C was treated with acupoint injection with Neostigmine in Dachangshu (BL 25), Zusanli (ST 36) etc. in addition to the treatment used in group A. Group D was treated with all of the treatments used in group A, B and C. The total effective rate was 93. 3% in group A, 96. 7% in group B, 100.0% in group C and group D. There was no significant difference among the four groups (P>0. 05). The average recovery time of bowel sound was (11. 512. 9) days in group A, (9. 3 +/- 2.5) days in group B, (5.6 +/- 3.5) days in group C and (2. 2 +/- 1.7) days in group D. The average anal exsufflation time was (12. 5 +/- 3. 1) days in group A, (10. 7 +/- 3.6) days in group B, (7. 2 +/- 3. 1) days in group C and (2. 5 +/- 1. 5) days in group D. Group D was superior to those of other three groups obviously, and there were significant differences between them (all P<0. 01). Electroacupuncture combined with acupoint injection has a satisfied therapeutic effect for treatment of EPISBO.

    Study objectives To evaluate the patients’ baseline condition upon arrival in the PACU as a method of assessment of the quality of anaesthesia, and to establish a model for future comparisons. Design Prospective observational study. Setting Surgical PACU in an academic tertiary hospital. Patients All patients (n = 11,241) arriving in our hospital’s recovery units after elective surgery. Interventions In this observational study, clinical data, vital signs and comfort parameters were collected from surgical patients who arrived in the PACU. For each parameter, its frequency distribution or percentage of occurrence was determined. Main results The incidence of anaesthesia associated side effects such as hypoxemia, cold extremities, shivering and/or vomiting was 5%. The incidence of nausea, sore throat, headache and/or pruritus was 9%. Sore throat occurred in 4.8% of intubated patients, in 4% after laryngeal mask insertions and in 3.6% with no usage of any airway device. From all patients 48% had no pain at all (VAS = 0), 31% had low pain scores (VAS 1–3) and 16% had moderate (VAS 4–6) pain levels, while 5% indicated severe pain (VAS 7–10). 97.5% of patients were normothermic (35.0–37.3°C), 77% had normal heart rate (60–100 beats per minute) and 74% had normal systolic blood pressure (90–140 mmHg). After use of neuromuscular relaxants, moderate clinical signs of residual curarisation (2 of 3 clinical criteria positive) were observed in 1% and slight clinical signs of residual curarisation (1 of 3 clinical criteria positive) were observed in 22.4% of patients. These findings were collected in all patients, independently whether they had reversal of neuromuscular relaxation. Conclusions Compared with the figures published in the literature, we report a lower incidence and severity of anaesthesia related side effects, measured as baseline data, upon patients’ arrival in the post anaesthesia care unit. The baseline data may serve as a model to trigger

    Full Text Available Objectives: To analyze the IOP spikes after selective laser trabeculoplasty (SLT. Materials and Methods: Two hundred eyes of 100 patients who applied to the clinic between 01.11.2010 and 31.10.2011 and who had primary SLT treatment with the diagnosis of primary open-angle glaucoma or ocular hypertension were enrolled in the study. Patients’ demographic data, iris color, angle pigmentation, and angle degree measurements with goniolens, pachymetry measurements by optic coherence tomography (OCT, cup/disk measurements (by indirect ophthalmoscopy, and IOP measurements (by applanation tonometry were noted. The relations between iris color, angle pigmentation, pachymetry and total energy with IOP spike and anterior chamber reactions observed at the 1st and 2nd hour of treatment were evaluated. Results: Thirty-seven percent of the patients were male and 63% of the patients were female. The mean age of males and females was 61.24±11.33 (33-85 and 58.21±12.35 (22-80, respectively. Mean IOP spikes and anterior chamber reactions at the 1st and 2nd hour of the treatment were 3.35 and 2.21 mmHg, respectively, and they were positively correlated (p=0.0001. As the eyes were examined according to iris color, statistically significant higher IOP spikes were observed in brown eyes (3.77 mmHg than in green (2.62 mmHg and hazel eyes (1.85 mmHg (p=0.0001. No significant relationship was found between IOP spikes and pachymetry and total energy whereas positive correlation was observed between IOP spikes and angle pigmentation (p1=0.904, p2=0.823, p3=0.0001. Conclusion: IOP spikes seen after SLT treatment were observed more frequently in dark colored eyes or in eyes with heavily pigmented angles. We believe, the follow-up of these patients requires attention. (Turk J Ophthalmol 2014; 44: 365-9

    Full Text Available Severe convective storms are responsible for large amount of damage each year around the world. They form an important part of the climate system by redistributing heat, moisture, and trace gases, as well as producing large quantities of precipitation. As these extreme and rare events are in mesoscale there is many uncertainty in predicting them and we can’t rely on just models. On the other hand, remote sensing has a large application in Meteorology and near real time weather forecasting, especially in rare and extreme events like convective storms that might be difficult to predict with atmospheric models. On second of June 2014, near 12UTC a sudden and strong convective storm occurred in Tehran province that was not predicted, and caused economic and human losses. In This research we used satellite observations along with synoptic station measurements to predict and monitor this storm. Results from MODIS data show an increase in the amount of cloudiness and also aerosol optical depth and sudden decrease in cloud top temperature few hours before the storm occurs. EUMETSAT images show the governing of convection before the storm occurs. With combining the observation data that shows Lake of humidity and high temperature in low levels with satellite data that reveals instability in high levels that together caused this convective, we could track the storm and decrease the large amount of damage.

    It is of great importance to understand biochemical system's behavior toward environmental perturbation during the development of living organisms. Here a microfluidic platform for Drosophila embryo's online development and observation is presented. The system is capable of developing the embryo's anterior and posterior halves controlled at different temperature environments, and it can be easily coupled with a confocal microscope for real-time image acquisition. The microfluidic chip is consisted of a polymethylmethacrylate (PMMA) substrate with a thickness of 4.0 mm and a polydimethylsiloxane (PDMS) cover designed with a typical 'Y' channel with a depth of 400 μm, width of 800 μm. Temperature gradients were created across the anterior half and posterior half of the embryo by utilizing two streams of laminar flow with different temperatures. It was found that thermal gradient would result in asynchronous development of the two halves of the embryos, and the developing difference was related to the direction of thermal gradient. This may result from the presence of an unknown mechanism located in the anterior half of the embryo, which oversees nuclear division synchronicity. These observations would help better understand compensatory mechanisms of Drosophila embryo's development under environmental perturbations. Copyright © 2017 Elsevier B.V. All rights reserved.

    Because of the lack of reliable sunspot observations, the quality of the sunspot number series is poor in the late 18th century, leading to the abnormally long solar cycle (1784-1799) before the Dalton minimum. Using the newly recovered solar drawings by the 18-19th century observers Staudacher and Hamilton, we construct the solar butterfly diagram, i.e., the latitudinal distribution of sunspots in the 1790s. The sudden, systematic occurrence of sunspots at high solar latitudes in 1793-1796 unambiguously shows that a new cycle started in 1793, which was lost in the traditional Wolf sunspot series. This finally confirms the existence of the lost cycle that has been proposed earlier, thus resolving an old mystery. This Letter brings the attention of the scientific community to the need of revising the sunspot series in the 18th century. The presence of a new short, asymmetric cycle implies changes and constraints to sunspot cycle statistics, solar activity predictions, and solar dynamo theories, as well as for solar-terrestrial relations.

    Full Text Available Background Phytoestrogens consumption is targeted as a possible way to achieve hormonal permeation in postmenopausal women. However, their health effect could depend on their bioavailability. Objectives As phytoestrogens bioavailability could be improved by modulating intestinal microflora, the present study was undertaken to investigate whether isoflavones and pre-or probiotics may improve bone markers. Design An intervention trial (2 months was carried out on 39 postmenopausal women receiving 100 mg of IF aglycon equivalents daily, incorporated in two jelly milk and two cereal bars. After the first month, the participants were randomised into three treatment groups: soy (control group, soy + fructooligosaccharides (prebiotics group and soy + yoghurt cultures (probiotics group. Results Level of isoflavone intake was associated with a significant increase in plasma isoflavone levels from baseline to day 15 which was maintained until day 60. Probiotics consumption was associated with increased plasma equol levels at day 60. A 5% increase of bone alkaline phosphatase was elicited on day 30, compared to initial values. Pre- or probiotics did not modulate this parameter. Urinary deoxypyridinoline excretion was slightly increased at day 60. Prebiotics and probiotics consumption improved this parameter. The effect of prebiotics was exacerbated in early compared to late postmenopausal women. Conclusion Addition of prebiotics or probiotics to a diet providing isoflavones is able to improve parameters of bone turnover in early menopause.

    The 50th anniversary of the discovery of quasars in 1963 presents an interesting opportunity to ask questions about the current state of quasar research. Formatted as a series of interviews with noted researchers in the field, each of them asked to address a specific set of questions covering topics selected by the editors, this book deals with the historical development of quasar research and discusses how advances in instrumentation and computational capabilities have benefitted quasar astronomy and have changed our basic understanding of quasars. In the last part of the book the interviews address the current topic of the role of quasars in galaxy evolution. They summarise open issues in understanding active galactic nuclei and quasars and present an outlook regarding what future observational facilities both on the ground and in space might reveal. Its interview format, the fascinating topic of quasars and black holes, and the lively recollections and at times controversial views of the contributors make ...

  18. Perspectives on using nonhuman primates to understand the etiology and treatment of postmenopausal osteoporosis.

    2001-06-01

    The reproductive physiology and skeletal anatomy of nonhuman primates are very similar to those of women and these similarities have prompted studies of the effects of ovariectomy in monkeys on bone metabolism. Following ovariectomy, monkey bone exhibits increases in remodeling activity resulting in bone loss. Since similar bone changes occur after menopause in women, ovariectomized monkeys provide an excellent model of the early skeletal events following menopause and have been employed to study the skeletal actions of drugs designed to treat postmenopausal osteoporosis. This review describes the motivations for examining monkeys, practical aspects of working with monkeys, comparisons of human and monkey bone anatomy, endocrinological aspects of monkey bone metabolism, and the available data obtained in monkeys related to postmenopausal and other forms of osteoporosis.

    To determine whether early mobilization of patients with severe acquired brain injury, performed in the intensive/neurointensive care unit, influences functional outcome. Prospective observational study. Fourteen centres in Italy. A total of 103 consecutive patients with acquired brain injury. Clinical, neurological and functional data, including the Glasgow Coma Scale (GCS), Disability Rating Scale (DRS), the Rancho Los Amigos Levels of Cognitive Functioning (LCF), Early Rehabilitation Barthel Index (ERBI), Glasgow Outcome Scale (GOS), and Functional Independence Measure (FIM) were collected at admission and every 3?5 days until discharge from the intensive/neurointensive care unit. Patients were divided into mobilization and no mobilization groups, depending on whether they received mobilization. Data were analysed by intragroup and intergroup analysis using a multilevel regression model. Sixty-eight patients were included in the mobilization group. At discharge, both groups showed significant improvements in GCS, DRS, LCF and ERBI scores. The mobilization group showed significantly better improvements in FIM cognitive, GOS and ERBI. The patients in the mobilization group stayed longer in the intensive care unit (p=0.01) and were more likely to be discharged to intensive rehabilitation at a significantly higher rate (p=0.002) than patients in the no mobilization group. No adverse events were reported in either group. Early mobilization appears to favour the clinical and functional recovery of patients with severe acquired brain injury in the intensive care unit.

    An early diagnosis of Intensive Care Unit-acquired weakness (ICU-AW) using muscle strength assessment is not possible in most critically ill patients. We hypothesized that development of ICU-AW can be predicted reliably two days after ICU admission, using patient characteristics, early available clinical parameters, laboratory results and use of medication as parameters. Newly admitted ICU patients mechanically ventilated ≥2 days were included in this prospective observational cohort study. Manual muscle strength was measured according to the Medical Research Council (MRC) scale, when patients were awake and attentive. ICU-AW was defined as an average MRC score prediction model was developed by selecting predictors from an a-priori defined set of candidate predictors, based on known risk factors. Discriminative performance of the prediction model was evaluated, validated internally and compared to the APACHE IV and SOFA score. Of 212 included patients, 103 developed ICU-AW. Highest lactate levels, treatment with any aminoglycoside in the first two days after admission and age were selected as predictors. The area under the receiver operating characteristic curve of the prediction model was 0.71 after internal validation. The new prediction model improved discrimination compared to the APACHE IV and the SOFA score. The new early prediction model for ICU-AW using a set of 3 easily available parameters has fair discriminative performance. This model needs external validation.

    Behaviour of early life stages of the salmonid European grayling Thymallus thymallus was investigated by assessing the timing of larval downstream movement from spawning areas, the depth at which larvae moved and the distribution of juvenile fish during summer in two large connected river systems in Norway. Trapping of larvae moving downstream and electrofishing surveys revealed that T. thymallus larvae emerging from the spawning gravel moved downstream predominantly during the night, despite light levels sufficient for orientation in the high-latitude study area. Larvae moved in the water mostly at the bottom layer close to the substratum, while drifting debris was caught in all layers of the water column. Few young-of-the-year still resided close to the spawning areas in autumn, suggesting large-scale movement (several km). Together, these observations show that there may be a deliberate, active component to downstream movement of T. thymallus during early life stages. This research signifies the importance of longitudinal connectivity for T. thymallus in Nordic large river systems. Human alterations of flow regimes and the construction of reservoirs for hydropower may not only affect the movement of adult fish, but may already interfere with active movement behaviour of fish during early life stages. © 2017 The Fisheries Society of the British Isles.

    To compare leukocyte telomere length (LTL) by race and describe demographic, health, and psychosocial factors associated with LTL in postmenopausal women. Descriptive study with comparative analyses and correlations. Data were collected at the University of California-San Francisco, San Francisco Clinical and Translational Science Institute. Thirty-nine African American and White postmenopausal women between 58 and 65 years of age (mean age = 61.3 ± 1.83 years). Measures included demographics, blood pressure, anthropometrics, scores on the Perceived Stress Scale and the Center for Epidemiologic Studies-Depression, and blood samples for LTL. African American women (n = 14) had greater PSS-10 and CES-D scores, greater blood pressure, and greater body mass index than White women (n = 25; p stress (p = .036) were related to shorter LTL. Findings from this small sample support the association between age and LTL. The association between perceived stress, number of children, and shorter LTL in postmenopausal women requires further research and replication of findings in a larger, more diverse sample.

    Full Text Available Abstract Introduction: The multiple aspects of disability in patients with osteoporosis require comprehensive tool for their assessment. The International Classification of Functioning, Disability and Health (ICF is designed to describe the experience of such patients with theirs functioning. Objective: This study aimed to describe the functioning in a sample of active postmenopausal women with osteoporosis according to the brief ICF core set for osteoporosis. Methods: This cross-sectional study was conducted among active community-dwelling older adults in a southern Brazilian city. Participants were enrolled by convenience sampling from a group conducting supervised aquatic and land-based exercises. Active postmenopausal women with osteoporosis were included. Thirty-two women (mean age 68.0 ± 5.1 years old participated in the evaluation. The brief ICF core set for osteoporosis was used to establish functional profiles. The categories were considered valid when ≥20% of participants showed some disability (according to ICF qualifiers. Results: No category showed a high level of disability, as >50% of women rated by qualifiers .3 or .4. Only the category e580 was considered by all participants as a facilitator. Conclusion: The brief ICF core set for osteoporosis results demonstrated that this classification system is representative to describe the functional profile of the sample. Active postmenopausal women with osteoporosis presented few impairments related to body functions and structures, activities and participation and environmental factors.

    After mechanical ventilation, extubation failure is associated with poor outcomes and prolonged hospital and intensive care unit (ICU) stays. We hypothesize that specific and unique risk factors exist for failed extubation in trauma patients. The purpose of this study was to identify the risk factors in trauma patients. We performed an 18-month (January 2008-June 2009) prospective, cohort study of all adult (8 years or older) trauma patients admitted to the ICU who required mechanical ventilation. Failure of extubation was defined as reintubation within 24 hours of extubation. Patients who failed extubation (failed group) were compared with those who were successfully extubated (successful group) to identify independent risk factors for failed extubation. A total of 276 patients were 38 years old, 76% male, 84% sustained blunt trauma, with an mean Injury Severity Score = 21, Glasgow Coma Scale (GCS) score = 7, and systolic blood pressure = 125 mm Hg. Indications for initial intubation included airway (4%), breathing (13%), circulation (2%), and neurologic disability (81%). A total of 17 patients (6%) failed extubation and failures occurred a mean of 15 hours after extubation. Independent risk factors to fail extubation included spine fracture, airway intubation, GCS at extubation, and delirium tremens. Patients who failed extubation spent more days in the ICU (11 vs. 6, p = 0.006) and hospital (19 vs. 11, p = 0.002). Mortality was 6% (n = 1) in the failed group and 0.4% (n = 1) in the successful extubation group. Independent risk factors for trauma patients to fail extubation include spine fracture, initial intubation for airway, GCS at extubation, and delirium tremens. Trauma patients with these four risk factors should be observed for 24 hours after extubation, because the mean time to failure was 15 hours. In addition, increased complications, extended need for mechanical ventilation, and prolonged ICU and hospital stays should be expected for trauma patients

    Background Research is a major driver of health care improvement and evidence-based practice is becoming the foundation of health care delivery. For health professions to develop within emerging models of health care delivery, it would seem imperative to develop and monitor the research capacity and evidence-based literacy of the health care workforce. This observational paper aims to report the research capacity levels of statewide populations of public-sector podiatrists at two different time points twelve-months apart. Methods The Research Capacity & Culture (RCC) survey was electronically distributed to all Queensland Health (Australia) employed podiatrists in January 2011 (n = 58) and January 2012 (n = 60). The RCC is a validated tool designed to measure indicators of research skill in health professionals. Participants rate skill levels against each individual, team and organisation statement on a 10-point scale (one = lowest, ten = highest). Chi-squared and Mann Whitney U tests were used to determine any differences between the results of the two survey samples. A minimum significance of p  6). Whereas, most reported their organisation’s skills to perform and support research at much higher levels (Median > 6). The 2012 survey respondents reported significantly higher skill ratings compared to the 2011 survey in individuals’ ability to secure research funding, submit ethics applications, and provide research advice, plus, in their organisation’s skills to support, fund, monitor, mentor and engage universities to partner their research (p < 0.05). Conclusions This study appears to report the research capacity levels of the largest populations of podiatrists published. The 2011 survey findings indicate podiatrists have similarly low research capacity skill levels to those reported in the allied health literature. The 2012 survey, compared to the 2011 survey, suggests podiatrists perceived higher skills and support to initiate

    Although hypotheses have been proposed regarding the biological mechanisms of hormonal fluctuations in mood disorders, few epidemiological studies have addressed this issue. The aim of this study was to examine the association between hormone-related life events and postmenopausal depression. Of 13,918 women who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) V, a total of 4869 post-menopausal women who had completed information on depression onset age and additional reproductive factors were included in the analysis. A multivariate logistic regression was applied to calculate the odds ratios between reproductive factors and post-menopausal onset depression. A total of 276 women (5.7%) were diagnosed with depression after menopause. Longer reproductive years were associated with a reduced risk of depression (for more than 35 reproductive years: OR=0.41, 95% CI: 0.27-0.62, P-trenddepression (OR=0.35, 95% CI: 0.22-0.55) compared to the women with a menopausal age younger than 46 years. Greater numbers of pregnancies and exogenous hormone use were also associated with increased risk of depression. All data were collected from interviews using questionnaires. There may be some inaccuracies in recall of lifetime reproductive events, but women generally recalled their hormonal events correctly. Early menopause and the use of exogenous hormones were associated with the risk of post-menopausal depression. Clinicians should closely monitor and consider further screening for depressed women who undergo early menopause or those with exogenous hormone use. Copyright © 2015 The Authors.

    Menopausal changes expose an individual towards risk of various pathologies during midlife transition. This study aimed to investigate the possible association of bone mineral density (BMD) with periodontal parameters in early postmenopausal Indian women. In 78 dentate postmenopausal female patients periodontal examination was performed including clinical attachment loss, pocket depth, plaque index and sulcular bleeding index. Alveolar crestal height was measured on proximal surfaces of all posterior teeth except third molars with the help of bitewing radiographs. Patient's BMD was assessed with dual energy X-ray absorptiometry. Statistical analysis was performed to assess the correlation between BMD and periodontal parameters. Pocket depth, clinical attachment loss and alveolar crestal height were found to have negative and statistically significant (P = -0.000 each) correlation with T-score, with the value of Pearson's correlation coefficient being -0.474, -0.426, and -0.419 respectively. Number of teeth lost due to periodontitis was not significantly correlated with T-score (P > 0.05). Results of anova and the post-hoc Tukey test revealed a statistically significant difference of mean clinical attachment loss, pocket depth and alveolar crestal height for the osteoporotic versus osteopenic group and the osteoporotic versus normal group. However, between the osteopenic and normal group, the differences of mean were statistically nonsignificant (P > 0.05). Body mass index was found to have a weakly positive (r = 0.376) and statistically significant (P = 0.001) correlation with T-score. Bone mineral density is an important risk indicator for periodontitis in postmenopausal women. Number of teeth lost due to periodontitis is not significantly affected by the BMD of the early postmenopausal phase. © 2013 Wiley Publishing Asia Pty Ltd.

    Menopause is associated with many unpleasant symptoms which vary in different phases of menopausal transition. Although, Hormone Replacement Therapy (HRT) is considered the most effective mode of treatment for these symptoms, its use is associated with increased risk of breast cancer, endometrial cancer and thromboembolic events. Soy isoflavones are being widely used as a safer alternative to HRT, even though scientific evidence of their efficacy is poor or lacking. To study the effect of soy isoflavone supplementation on the menopausal symptoms in perimenopausal and postmenopausal women. An observational pilot study was done involving 29 perimenopausal and 21 postmenopausal women prescribed 100 mg soy isoflavones for 12 weeks. Menopause Rating Scale (MRS) questionnaire was administered to the patients before starting soy isoflavone therapy and at the end of treatment. Responses were analysed using Statistical Package for Social Sciences (SPSS) software 23.0. Total score of both the groups were comparable at baseline. Among perimenopausal women highest score was given to symptoms of psychological domain. Urogenital symptoms were the worst among postmenopausal women. After 12 weeks of treatment, total scores improved significantly by 19.55% and 12.62% in the perimenopausal and postmenopausal women respectively. The greatest improvement was seen in scores of hot flashes for both the groups and the least improvement was shown by symptoms of urogenital subscale. Soy isoflavone improves the MRS score among both the perimenopausal and postmenopausal women. As they are most effective for somatic and psychological symptoms, their use could be beneficial during perimenopause.

    Osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. Osteoporosis can be diagnosed easily with the use of dual-energy X-ray absorptiometry equipment. The aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine in pre-and post-menopausal women from Isfahan Osteoporosis Diagnosis Center since 2005. Materials and Methods: Bone mineral density measurements using dual-energy X-ray absorptiometry have been performed at Isfahan Osteoporosis Diagnosis Center. 185 pre-menopausal and 174 early post-menopausal women were selected randomly. A Norland XR46 system was used for the investigations. The student t-lest was done to find the difference between the T-scores of the femoral neck and lumbar spine in pre-and post-menopausal women. Results: Mean Bone mineral density for the femoral neck and lumbar spine in pre-menopausal women were 0.859 ± 0.136 and 1.012 ± 0.161 and in post-menopausal women were 0.816 ± 0.119 and 0.919 ± 0.140, respectively. Long-term Bone mineral density CVs of 1.0% and 1.2% for the lumbar spine and femoral neck were found, respectively. The differences between the femoral neck and lumbar spine for pre-and post-menopausal women were t = -9.02, P < 0.05 and t = -3.50, P < 0.05, respectively. Conclusion: In spite of, the reported lower Bone mineral density T-scores for the lumbar spine compared With the femoral neck for women, we found that the femoral neck had significantly lower T-score than lumbar spine for both pre-and post-menopausal women.

    The Group on Earth Observations' Global Agricultural Monitoring (GEOGLAM) implementation plan emphasizes the information needs of countries at risk of food insecurity emergencies. Countries in this category are often vulnerable to disruption of agricultural production due to drought, while at the same time they lack well developed networks of in-situ observations to support early drought detection. Consequently, it is vital that Earth observations by satellites supplement those available from surface stations. The USGS, in its role as a FEWS NET implementing partner, has recently developed a number of new applications of satellite observations for this purpose. (1) In partnership with the University of California, Santa Barbara, a 30+ year time series of gridded precipitation estimates (CHIRPS) has been developed by blending NOAA GridSat B1 geostationary thermal infrared imagery with station observations using robust geostatistical methods. The core data set consists of pentadal (5-daily) accumulations from 1981-2013 at 0.05 degree spatial resolution between +/- 50 degrees latitude. Validation has been recently completed, and applications for gridded crop water balance calculations and mapping the Standardized Precipitation Index are in development. (2) Actual evapotranspiration (ETa) estimates using MODIS Land Surface Temperature (LST) data at 1-km have been successfully demonstrated using the operational Simplified Surface Energy Balance model with 8-day composites from the LPDAAC. A new, next-day latency implementation using daily LST swath data from the NASA LANCE server is in development for all the crop growing regions of the world. This ETa processing chain follows in the footsteps of (3) the expedited production of MODIS 250-meter NDVI images every five days at USGS EROS, likewise using LANCE daily swath data as input since 2010. Coverage includes Africa, Central Asia, the Middle East, Central America, and the Caribbean. (4) A surface water point monitoring

This cross-sectional study was carried out from June 2015 to July 2016 at Jinnah Medical and Dental College, Karachi, and comprised postmenopausal women. Bone mineral density done by dual energy X-ray absorptiometryscan categorised subjects by World Health Organisation classification into normal (T score > -1) osteopenic (T score between -1 and -2.5) and osteoporotic (T score osteoporotic. There was significant difference in mean body mass index, serum tumour necrosis factor alpha and calcium in all the three groups (posteoporotic group (posteoporotic groups (p>0.05). A significant difference was observed for mean tumour necrosis factor alpha values between normal and osteoporotic groups (posteoporotic groups (p>0.05). Increased bone turnover in postmenopausal osteopenic women can be predicted by increased serum cytokine.

    The Intergovernmental Panel on Climate Change (IPCC 2007) has suggested the hydrometeorological extremes of both drought and flooding may increase under climate change. Drought zones can grow over large tracts of continental area and are a global-scale phenomenon (Sheffield and Wood 2011). The Group on Earth Observations Global Drought Monitor Portal (GDMP) was established as a demonstration for the 5th Earth Observation Ministerial Summit in Beijing in 2010. The European Drought Observatory, the North American Drought Monitor, the Princeton University experimental African Drought Monitor, and the University College London experimental global drought monitor were made "interoperable" through installation of Open Geospatial Consortium (OGC) Web Mapping Services (WMS) on their respective servers, allowing maps of current drought conditions to be exchanged and assembled into maps of global drought coverage on the NIDIS portal. Partners from the Republic of Argentina, the Commonwealth of Australia, China, Jordan, Brazil, and Uruguay have also joined. The GEO Global Drought Monitoring, Forecasting, and Early Warning effort involves multiple parties and institutions, including the World Meteorological Organization, the World Climate Research Program Drought Interest Group, NASA, and others. The GEO Secretariat held a launch workshop in Geneva on 4-6 May 2010 to initiate drafting the final GEO Work Plan, and, during this meeting, additional capabilities were added to the existing GDMP: 1) drought forecasting was added to drought "current conditions" monitoring, in a partnership with Joint Research Centre (and other partners) aiming at a combined platform for Hydrological Extremes (drought and flooding); 2) extending drought forecasts from the medium-range 15-day window to a 30-day window; this will be tested through pilot projects over Europe and Africa, as part of the Global Water Scarcity Information Service (GLOWASIS)and the Improved Drought Early Warning Forecasting

    We present the results of ROSAT Positive Sensitive Proportional Counter (PSPC) observations of the two early-type galaxies NGC 4365 and NGC 4382. These galaxies are among those observed with Einstein to have the lowest X-ray to optical flux ratios of early-type galaxies. The PSCP data show that for radii r greater than 50 arcsec the radial distributions of the X-ray surface brightness are consistent with the optical distributions of King (1978). We also find that these galaxies have X-ray spectra significantly different from those observed in X-ray-bright ellipticals, with a relative excess of counts detected in the softest spectral channels. This confirms earlier Einstein results. The characteristics of the ROSAT PSPC do not allow us to discriminate between possible spectral models. If we adopt a two-component thermal model on the grounds of physical plausibility, we find that the spectral data can be fitted with a very soft optically thin component, with kT approximately 0.2 keV, and a hard component with kT greater than (1.0-1.5) keV. The hard component has a luminosity consistent with that expected from the integrated emission of a population of low mass-X-ray binaries in these galaxies; the nature of the very soft component is more speculative. Candidates include the coronal emission of late-type stars, supersoft X-ray sources, RS CVn, and perhaps a hot Interstellar Medium (ISM). Alternatively, the spectal data may be fitted with a 0.6-1 keV bremsstrahlung spectrum (expontential plus Gaunt), and may suggest the presence of a totally new population of X-ray sources.

    postprandial (AUC) TAG with BMI (r=0.385) and Ssk (r=0.406). A significantly higher postprandial apolipoprotein (apo) B-48 response was observed in those women with high BMI (> 27 kg/m2). Fasting levels of NEFA were significantly and positively correlated with all measures of adiposity (except W/H). No association was found between cholesterol containing particles and any measure of adiposity. Hyperinsulinaemia associated with increasing body fat and central fat distribution is associated with normal glucose but not TAG or NEFA concentrations in postmenopausal women.

  17. Impact of Estrogen Therapy on Lymphocyte Homeostasis and the Response to Seasonal Influenza Vaccine in Post-Menopausal Women.

    Full Text Available It is widely recognized that changes in levels of ovarian steroids modulate severity of autoimmune disease and immune function in young adult women. These observations suggest that the loss of ovarian steroids associated with menopause could affect the age-related decline in immune function, known as immune senescence. Therefore, in this study, we determined the impact of menopause and estrogen therapy (ET on lymphocyte subset frequency as well as the immune response to seasonal influenza vaccine in three different groups: 1 young adult women (regular menstrual cycles, not on hormonal contraception; 2 post-menopausal (at least 2 years women who are not receiving any form of hormone therapy (HT and 3 post-menopausal hysterectomized women receiving ET. Although the numbers of circulating CD4 and CD20 B cells were reduced in the post-menopausal group receiving ET, we also detected a better preservation of naïve B cells, decreased CD4 T cell inflammatory cytokine production, and slightly lower circulating levels of the pro-inflammatory cytokine IL-6. Following vaccination, young adult women generated more robust antibody and T cell responses than both post-menopausal groups. Despite similar vaccine responses between the two post-menopausal groups, we observed a direct correlation between plasma 17β estradiol (E2 levels and fold increase in IgG titers within the ET group. These findings suggest that ET affects immune homeostasis and that higher plasma E2 levels may enhance humoral responses in post-menopausal women.

    Full Text Available At present, not much is known about progesterone receptor (PR expression and localization in postmenopausal women ovaries. In the ovaries of reproductive age women, PR is localized in internal theca and granulosa cells, corpus luteum, ovary surface epithelium (OSE and in stroma. PR expression depends on the serum concentration of progesterone, estrogen, gonadotropin and androgen. The goal of the conducted studies was to examine PR localization and expression in the ovaries of postmenopausal women who have not applied hormone replacement therapy so far. Also, the correlation was examined between PR expression and localization in the ovaries, steroid and gonadotropin hormone serum concentrations, and influence of the time from the last menstruation. The material came from 50 postmenopausal women who had their ovaries removed due to non-neoplastic diseases. The women were divided into 3 groups (A, B, C depending on the time from the last menstruation. The follitropin (FSH, luteotropin (LH, estradiol (E2, testosterone (T, androstendione (A and dehydroepiandrosterone sulphate (DHEAS concentrations in blood plasma were measured. Monoclonal mouse anti-human PR antibody was used for immunohistochemical detection (examination involved 50 postmenopausal ovaries. Between particular groups, E2 serum concentrations did not differ, but FSH, LH, T, A, DHEAS serum concentrations were significantly different. Immunohistochemical nuclear localization of PR in postmenopausal women ovaries was observed. PR expression was similar in all three groups (A, B, C. PR expression was observed in OSE nuclei and invaginations cysts deriving from the isolation of invaginated epithelium and metaplastic columnar epithelium and in stroma. In the ovaries of postmenopausal women who have not applied hormone replacement therapy so far, PR was detected in all three groups. Its expression did not depend on the time from menopause and was similar in all examined groups. FSH, LH, T, A

    We describe the infrared properties of a large sample of early-type galaxies, comparing data from the Spitzer archive with Ks-band emission from the Two Micron All Sky Survey. While most representations of this data result in correlations with large scatter, we find a remarkably tight relation among colors formed by ratios of luminosities in Spitzer-Multiband Imaging Photometer bands (24, 70, and 160 μm) and the Ks band. Remarkably, this correlation among E and S0 galaxies follows that of nearby normal galaxies of all morphological types. In particular, the tight infrared color-color correlation for S0 galaxies alone follows that of the entire Hubble sequence of normal galaxies, roughly in order of galaxy type from ellipticals to spirals to irregulars. The specific star formation rate (SFR) of S0 galaxies estimated from the 24 μm luminosity increases with decreasing K-band luminosity (or stellar mass) from essentially zero, as with most massive ellipticals, to rates typical of irregular galaxies. Moreover, the luminosities of the many infrared-luminous S0 galaxies can significantly exceed those of the most luminous (presumably post-merger) E galaxies. SFRs in the most infrared-luminous S0 galaxies approach 1-10 solar masses per year. Consistently, with this picture we find that while most early-type galaxies populate an infrared red sequence, about 24% of the objects (mostly S0s) are in an infrared blue cloud together with late-type galaxies. For those early-type galaxies also observed at radio frequencies, we find that the far-infrared luminosities correlate with the mass of neutral and molecular hydrogen, but the scatter is large. This scatter suggests that the star formation may be intermittent or that similar S0 galaxies with cold gaseous disks of nearly equal mass can have varying radial column density distributions that alter the local and global SFRs.

    Group-sequential testing is widely used in pivotal therapeutic, but rarely in diagnostic research, although it may save studies, time, and costs. The purpose of this paper was to demonstrate a group-sequential analysis strategy in an intra-observer study on quantitative FDG-PET/CT measurements, illuminating the possibility of early trial termination which implicates significant potential time and resource savings. Primary lesion maximum standardised uptake value (SUVmax) was determined twice from preoperative FDG-PET/CTs in 45 ovarian cancer patients. Differences in SUVmax were assumed to be normally distributed, and sequential one-sided hypothesis tests on the population standard deviation of the differences against a hypothesised value of 1.5 were performed, employing an alpha spending function. The fixed-sample analysis (N = 45) was compared with the group-sequential analysis strategies comprising one (at N = 23), two (at N = 15, 30), or three interim analyses (at N = 11, 23, 34), respectively, which were defined post hoc. When performing interim analyses with one third and two thirds of patients, sufficient agreement could be concluded after the first interim analysis and the final analysis. Other partitions did not suggest early stopping after adjustment for multiple testing due to one influential outlier and our small sample size. Group-sequential testing may enable early stopping of a trial, allowing for potential time and resource savings. The testing strategy must, though, be defined at the planning stage, and sample sizes must be reasonably large at interim analysis to ensure robustness against single outliers. Group-sequential testing may have a place in accuracy and agreement studies.

    Full Text Available Systemic lupus erythematosus (SLE or lupus is a chronic inflammatory disease that occurs mainly in women. Typically, symptoms appear within the first few years of adolescence, but currently an increase can be observed in the percentage of postmenopausal women with this condition. This is possibly due to the sophisticated treatment of the disease, which significantly improves the survival curve and prognosis. Genetic and environmental factors are involved in the development of SLE. Both regulation of the immune system and the activity of this disease are influenced by a variety of hormones, including: 17-estradiol, testosterone, prolactin, progesterone and dehydroepiandrosterone (DHEA. Early menarche, menstrual cyclicity, the total number of years characterized by ovulatory cycles and early menopause are correlated with the development of SLE. Because of the health risks, attempts are increasingly being made to evaluate the impact of exogenous hormones (especially those applied exogenously on the course of SLE. In particular, the role of estrogens is being highlighted, either endo- or exogenous, including oral contraceptives (OC, therapy used in the treatment of infertility, and hormonal replacement therapy (HRT. The purpose of this manuscript is the revision of the literature concerning the impact of both endo- and exogenous estrogens on the development of lupus, inducement of flares and any possible complications.

    The Ultra-Fast Flash Observatory (UFFO) Burst Alert and Trigger Telescope (UBAT) has been designed and built for the localization of transient X-ray sources such as Gamma Ray Bursts (GRBs). As one of main instruments in the UFFO payload onboard the Lomonosov satellite (hereafter UFFO/ Lomonosov), the UBAT's roles are to monitor the X-ray sky, to rapidly locate and track transient sources, and to trigger the slewing of a UV/optical telescope, namely Slewing Mirror Telescope (SMT). The SMT, a pioneering application of rapid slewing mirror technology has a line of sight parallel to the UBAT, allowing us to measure the early UV/optical GRB counterpart and study the extremely early moments of GRB evolution. To detect X-rays, the UBAT utilizes a 191.1 cm2 scintillation detector composed of Yttrium Oxyorthosilicate (YSO) crystals, Multi-Anode Photomultiplier Tubes (MAPMTs), and associated electronics. To estimate a direction vector of a GRB source in its field of view, it employs the well-known coded aperture mask technique. All functions are written for implementation on a field programmable gate array to enable fast triggering and to run the device's imaging algorithms. The UFFO/ Lomonosov satellite was launched on April 28, 2016, and is now collecting GRB observation data. In this study, we describe the UBAT's design, fabrication, integration, and performance as a GRB X-ray trigger and localization telescope, both on the ground and in space.

    Temporally, spatially, and spectrally resolved x-ray image data from direct-drive implosions on OMEGA were interpreted with the aid of radiation-hydrodynamic simulations. Neither clean calculations nor those using a turbulent mix model can explain fully the observed migration of shell-dopant material (titanium) into the core. Shell-dopant migration was observed via time-dependent, spatially integrated spectra, and spatially and spectrally resolved x-ray images of capsule implosions and resultant dopant emissions. The titanium emission was centrally peaked in narrowband x-ray images. In post-processed clean simulations, the peak titanium emission forms in a ring in self-emission images as the capsule implodes. Post-processed simulations with mix reproduce trends in time-dependent, spatially integrated spectra, as well having centrally peaked Ti emission in synthetic multiple monochromatic imager. However, mix simulations still do not transport Ti to the core as is observed in the experiment. This suggests that phenomena in addition to the turbulent mix must be responsible for the transport of Ti. Simple diffusion estimates are unable to explain the early Ti mix into the core. Mechanisms suggested for further study are capsule surface roughness, illumination non-uniformity, and shock entrainment.

  6. First Stages of the Formation of the South Seasonal Cap in Early Southern Winter as Observed by OMEGA/Mex

    Observations in the visible [1] demonstrated that the retreat of the southern seasonal is very asymmetrical from Ls 230° to Ls 300°, ice extending much further North over a range of longitudes (270° E to 0° E) corresponding to the "bright cap". Observations by TES demonstrated that the bright regions corresponding to the visible cap are at the equilibrium temperature of CO2 ice, as well as the cryptic region, which exhibits low albedos (0.2 - 0.25) close to mid southern spring (Ls 225°). Observations by OMEGA/Mex have Mars Express have demonstrated that the Southern seasonal cap is indeed spectrally dominated by CO2 ice [3, 4]. The low albedo of the cryptic region results from dust contamination on the surface [3] most likely linked to a venting process [5] when CO2 ice sublimates in contact with the underlying surface. OMEGA observed that the very high albedos are linked to large equivalent grain sizes on the bright cap (270°E to 0°E) [4]. These characteristics have been associated with global climate evolution models [6, 7] with a major role played by the two large southern basins, Hellas and Argyre, in the circulation patterns [6]. A possible interpretation of the long lasting cap over the "bright cap" range of longitudes is that the CO2 deposit on the surface is initiated by the sedimentation of small CO2 ice grains or H2O ice grains on the surface followed by the condensation of a layer CO2 directly from the atmosphere. If this is the case, the surface underlying the bright cap regions is protected from photons penetrating the overlying large-grained CO2 layer, which inhibits the venting process, delaying the sublimation of the CO2 ice layer until late spring. Observations by OMEGA close to the southern terminator in early winter (Ls 15°) at high latitudes (70°) obtained in April 2004 and November 2009 correspond to very high incidences (~ 85° or more). This requires a careful evaluation of the aerosol contribution, at the limit of the range of

  7. Worse renal disease in postmenopausal F2[Dahl S x R]-intercross rats: detection of novel QTLs affecting hypertensive kidney disease.

    Full Text Available The prevalence of hypertension increases after menopause with 75% of postmenopausal women developing hypertension in the United States, along with hypertensive end organ diseases. While human and animal model studies have indicated a protective role for estrogen against cardiovascular disease and glomerulosclerosis, clinical studies of hormone replacement therapy in postmenopausal women have shown polar results with some improvement in hypertension but worsening of hypertensive kidney disease, or no effect at all. These observations suggest that the pathogenesis of postmenopausal hypertension and its target organ complications is more complex than projected, and that loss of endogenous estrogens induces epigenetic changes that alter genetic susceptibility to end-organ complications per se resulting in pathogenetic mechanisms beyond correction by hormone replacement. We studied postmenopausal-induced changes in renal disease and performed a total genome scan for quantitative trait loci (QTLs affecting kidney disease in postmenopausal 16m-old F2[Dahl S x R]-intercross female rats. We used glomerular injury score (GIS as quantitative trait. We compared QTLs amongst premenopausal, ovariectomized and postmenopausal F2[Dahl S x R]-intercross rats using identical phenotype characterization. Postmenopausal F2[Dahl S x R]-intercross rats exhibited increased hypertensive glomerulosclerosis (P<0.01 and equivalent levels of kidney disease when compared to premenopausal and ovariectomized F2[Dahl S x R]-intercross rats respectively. We detected three significant to highly significant GIS-QTLs (GIS-pm1 on chromosome 4, LOD 3.54; GIS-pm2 on chromosome 3, LOD 2.72; GIS-pm3 on chromosome 5, LOD 2.37 and two suggestive GIS-QTLs (GIS-pm4 on chromosome 2, LOD 1.70; GIS-pm5 on chromosome 7, LOD 1.28, all of which were unique to this postmenopausal population.

    This randomized, double-blind, placebo-controlled study was conducted to investigate the efficacy, safety and tolerability of policosanol, a cholesterol-lowering drug purified from sugar-cane wax, in postmenopausal women with type II hypercholesterolemia. A total of 244 women who had experienced the menopause and showed elevated serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels despite 6 weeks on a standard lipid-lowering diet were randomized to receive placebo or policosanol 5 mg/day for 12 weeks, after which the dose was doubled to 10 mg/day for the next 12 weeks. Policosanol (5 and 10 mg/day) significantly lowered LDL-C levels (17.7% and 25.2%, respectively) and total cholesterol (12.6% and 16.7%, respectively), as well as the ratios of LDL-C to high-density lipoprotein cholesterol (HDL-C) (17.0% and 29.3%, respectively) and total cholesterol to HDL-C (16.7% and 27.2%, respectively), compared to the baseline and placebo; at the same time, policosanol significantly raised HDL-C levels by 16.5% and 29.3%, respectively. The drug was safe and well tolerated. No drug-related adverse events were observed, and even the extent of adverse events was less in the policosanol group than in the placebo group. Four serious adverse events occurred in the placebo group (one myocardial infarction, two cases of hypertensive status and one surgical intervention) compared to none in the policosanol group. In conclusion, policosanol is effective, safe and well tolerated in hypercholesterolemic postmenopausal women.

They were split in two groups. Patients of the first group (30 people received enalapril (Berlipril® 20 mg/daily, patients of the second group (30 people – diltiazem (Altiazem® PP 180-360 mg/daily. Observation period was 6 months. Ambulatory blood pressure monitoring (ABPM was performed before treatment and after 3 weeks, 1, 3 and 6 months of therapy. Climacteric syndrome severity and urodynamic disorders was estimated as well as psychic status according to score of depression and anxiety.Results. Office and ambulance blood pressure decreased after 6 months of therapy in all patients of both groups. A number of complaints on headache and giddiness reduced significantly. Severity of climacteric syndrome also decreased. Enalapril (Berlipril® monotherapy and especially combined therapy with hydrochlorothiazide led to aggravation of urodinamic disorders. On the contrary both monotherapy with diltiazem (Altiazem® PP or its combination with hydrochlorothiazide had positive effect on urodinamics. Both therapies reduced depression and anxiety levels significantly.Conclusion. All spectrum of pharmacology effects should be taken into account during antihypertensive therapy of patients with climacteric disorders.

    Menopause is marked by a decline in ovarian function resulting in one or more climacteric symptoms. In the last few years, attention has been focused on the use of selective serotonin reuptake inhibitors (SSRIs) in the treatment of vasomotor symptoms associated with the menopausal transition. Thanks to the recent findings on the interaction between the serotoninergic system and neurotrophins, it has been suggested that brain-derived neurotrophic factor (BDNF) could contribute to the activity of SSRIs. Moreover, because endogenous gonadal hormones modulate both BDNF expression and serotonin biosynthesis and bioavailability and regulate brain functions like affective and cognitive functions, we proposed to evaluate the effects of a treatment with paroxetine, an SSRI, in a group of postmenopausal women and to clarify the possible relationship between paroxetine, plasma BDNF levels, and climacteric symptoms. A total of 119 postmenopausal women (age, 46-60 y; menopause age, 1-20 y) were included; 89 took paroxetine 10 mg/day for 6 months and 30 took estrogen + progestogen therapy (EPT) for 6 months. Blood samples were taken before the beginning of the therapy and at 3 and 6 months. The Green Climacteric Scale questionnaire was used to follow up women's clinical conditions. Plasma BDNF levels significantly increased after 3 and 6 months of therapy (P menopause age persisted throughout the treatment. Moreover, a significant reduction in the Greene Climacteric Scale score was observed. In the EPT group, the plasma BDNF level significantly increased after 6 months of therapy. The plasma BDNF levels after 6 months of paroxetine were significantly lower than those after 6 months of EPT. The present data suggest that a low dose of paroxetine is effective in enhancing plasma BDNF levels, and this increase might have a role in improving climacteric symptoms, highlighting the possible role of BDNF in endocrinological and cognitive functions.

    Long-term observations of ecological communities are necessary for generating and testing predictions of ecosystem responses to climate change. We investigated temporal trends and spatial patterns of soil fauna along similar environmental gradients in three sites of the McMurdo Dry Valleys, Antarctica, spanning two distinct climatic phases: a decadal cooling trend from the early 1990s through the austral summer of February 2001, followed by a shift to the current trend of warming summers and more frequent discrete warming events. After February 2001, we observed a decline in the dominant species (the nematode Scottnema lindsayae) and increased abundance and expanded distribution of less common taxa (rotifers, tardigrades, and other nematode species). Such diverging responses have resulted in slightly greater evenness and spatial homogeneity of taxa. However, total abundance of soil fauna appears to be declining, as positive trends of the less common species so far have not compensated for the declining numbers of the dominant species. Interannual variation in the proportion of juveniles in the dominant species was consistent across sites, whereas trends in abundance varied more. Structural equation modeling supports the hypothesis that the observed biological trends arose from dissimilar responses by dominant and less common species to pulses of water availability resulting from enhanced ice melt. No direct effects of mean summer temperature were found, but there is evidence of indirect effects via its weak but significant positive relationship with soil moisture. Our findings show that combining an understanding of species responses to environmental change with long-term observations in the field can provide a context for validating and refining predictions of ecological trends in the abundance and diversity of soil fauna. © 2018 by the Ecological Society of America.

    Full Text Available Background Every woman during different stages of her growth faces various crises, and one of these crises, menopause, may create different problems. In modern societies, psychological disorders and particularly depression is one of the problems of menopausal women. Objectives This study aimed to evaluate the prevalence of depression in postmenopausal women referred to selected health centers of Ahvaz in 2014. Patients and Methods This study was cross-sectional study. In this study, 1280 postmenopausal women aged between 40 and 65 years old who were referred to selected health centers of Ahvaz in 2014 were randomly enrolled. Hamilton depression scale and demographic questionnaire were used for gathering information. Data were analyzed using SPSS software. To analyze the data, descriptive statistics and analytical statistics (Independent t test, ANOVA, Pearson correlation and logistic regression were carried out (CI 95%. Results The mean ± SD score of depression for the subjects was 9.37 ± 4.62. The results showed that 59.8% of the 1280 samples were depressed; in particular, 39.8% had mild depression, 16% moderate depression, and 4% severe depression. There is a significant and inverse relation between variables of age, exposure to cigarette smoking, and the relationship with their spouses and the level of their depression, so higher age, more exposure to smoking, and better relation with their husbands, lead to the less depression. The results showed that the level of education is associated with depression. The highest rate of depression was in illiterate women; the finding also showed that there is a relationship between income and the severity of depression (Regression Log. T test showed that the mean depression level of employed postmenopausal women is higher than housewives postmenopausal women, and this difference is statistically significant (P < 0.001. Conclusions A significant percentage of women in their menopause experience

    Osteoporosis is a systemic skeletal disorder characterized by reduced bone mineral density (BMD) and disrupted bone architecture, predisposing the patient to increased fracture risk. Evidence from early genetic epidemiological studies has indicated a major role for genetics in the development of osteoporosis and the variation in BMD. In this study, we focused on two key genes in the endochondral ossification pathway, IBSP and PTHLH. Over 9,000 postmenopausal Han Chinese women were recruited, and 54 SNPs were genotyped. Two significant SNPs within IBSP, rs1054627 and rs17013181, were associated with BMD and postmenopausal osteoporosis by the two-stage strategy, and rs17013181 was also significantly associated with serum IBSP levels. Moreover, one haplotype (rs12425376-rs10843047-rs42294) covering the 5' end of PTHLH was associated with postmenopausal osteoporosis. Our results provide evidence for the association of these two key endochondral ossification pathway genes with BMD and osteoporosis in postmenopausal Han Chinese women. Combined with previous findings, we provide evidence that a particular SNP in IBSP has an allele-specific effect on mRNA levels, which would, in turn, reflect serum IBSP levels.

    Coronal mass ejections (CMEs), one of the most energetic manifestations of solar activity, are complex events, which combine multiple related phenomena occurring on the solar surface, in the extended solar atmosphere (corona), as well as in interplanetary space. We present here an outline of a new collaborative project between scientists from the Bulgarian Academy of Sciences (BAS), Bulgaria and the University of Graz, Austria. The goal of the this research project is to answer the following questions: 1) What are the properties of erupting filaments, CMEs, and CME-driven shock waves near the Sun, and of associated solar energetic particle (SEP) fluxes in interplanetary space? 2) How are these properties related to the coronal acceleration of SEPs? To achieve the scientific goals of this project, we will use remote solar observations with high spatial and temporal resolution to characterize the early stages of coronal eruption events in a systematic way - studying the pre-eruptive behavior of filaments and flares during energy build-up, the kinematics and morphology of CMEs and compressive shock waves, and the signatures of high energy non-thermal particles in both remote and in situ observations.

    This study sought to investigate the effects of vitamin D supplementation and aquatic exercise on pulmonary function in postmenopausal women. This prospective and controlled study included 104 women (62 ± 6.5 years) divided into three groups: a control group lacking vitamin D and calcium supplementation which remained sedentary (CG; n = 17); a control group receiving vitamin D and calcium supplementation which remained sedentary (CDG, n = 33); and a group that completed aquatic exercises three times a week and received vitamin D and calcium supplementation (DTG, n = 54). Data before and after 6 months of the study were analyzed, including serum 25-hydroxyvitamin D (25(OH)D) and calcium concentrations, peak expiratory flow (PEF), forced vital capacity (FVC), and cirtometry. We observed significant increases in 25(OH)D concentrations in CDG (52.9 ± 2.4 to 69.1 ± 2.2; nmol/L; p vitamin D supplementation improves pulmonary function parameters in postmenopausal women.

    Leptin has a significant role in body weight regulation and energy balance. We examined the effect of tibolone on the body weight and serum leptin levels in postmenopausal women. Twenty women (aged 43-60 years) participated in this prospective study. All women in this study protocol received 2.5 mg/day of tibolone. Absolute and body mass index (BMI)-corrected serum leptin concentrations and BMI values were measured at baseline, after 3 months, and after 6 months of the tibolone therapy. Tibolone did not affect absolute and BMI-corrected serum leptin levels, and BMI values during the treatment. A significant linear correlation between BMI values and serum leptin levels was observed (p<0.05, r=0.67). Tibolone seems not to affect serum leptin levels, body weight and BMI values of postmenopausal women. There is a significant correlation between serum leptin levels and BMI values.

    The aim of this work was to perform a comparative study between three recently developed biochemical markers of bone resorption derived from collagen metabolism--(1) total urinary free pyridinolines (Pyr), (2) serum pyridinoline cross-linked carboxy-terminal telopeptides of type I collagen (ICTP) and (3) a urinary-specific sequence for a part of the C-telopeptide of the alpha 1 chain of type I collagen (CTX)--in the diagnosis and follow-up of postmenopausal osteoporosis. Results were also evaluated relative to the classical biochemical marker urinary hydroxyproline (Hyp). The study included 20 untreated osteoporotic postmenopausal women (OSP), age 60 +/- 6 years, range 46-69 years; 27 osteoporotic postmenopausal women treated (OSP-T) by cyclic therapy with disodium etidronate, 25-hydroxyvitamin D and calcium for a period between 3 months and 4 years (25 +/- 15 months), age 59 +/- 7 years, range 41-67 years; 17 osteopenic postmenopausal women, age 57 +/- 6 years, range 46 +/- 68 years; and 29 healthy control postmenopausal women, age 56 +/- 7 years, range 41-70 years. The diagnostic criterion for postmenopausal osteoporosis was a bone mineral density (BMD) (Hologic QDR-1000) in lumbar spine and/or femoral neck more than 2 SD below the mean value corresponding to an age- and sex-matched healthy control group. For inclusion in the osteopenic group BMD values had to be between 1 and 2 SD below the mean BMD value corresponding to the control group. We found a significant increase (p < 0.01) in the levels of Pyr/Cr and CTX/Cr (Cr = creatinine) in OSP patients with respect to the control group and we did not observe any significant difference between control and OSP-T or osteopenic women. It is interesting to note that there was a mean increase in CTX/Cr in OSP patients of 101% of the control values, while the mean increase found in Pyr/Cr concentration was only 33%. However, we did not find significant differences in the concentrations of ICTP and Hyp/Cr between groups

    Studies have reported current hormonal contraceptive use is associated with adverse cardiovascular outcomes, including high blood pressure. The aim of this study was to determine the association between past hormonal contraception use and high blood pressure in Australian postmenopausal women. Women were recruited from the 45 and Up Study, an observational cross-sectional study, conducted from February 2006 to December 2009, NSW Australia. All of the variables used in this study were derived from self-reported data. These women reported being postmenopausal, having an intact uterus, and had given birth to one or more children. Odds ratios and 99% confidence intervals for the association between past hormonal contraceptive use and current treatment for high blood pressure, stratified by current age (high blood pressure, menopausal hormone therapy use, number of children, whether they breastfed, and age of menopause. A total of 34,289 women were included in the study. No association between past hormonal contraception use and odds of having high blood pressure were seen in any of the age groups (high blood pressure was observed. Past hormonal contraception use and duration of use is not associated with high blood pressure in postmenopausal women.

    Harmful alcohol consumption, particularly alcohol use disorder (AUD), is a worldwide health priority, contributing substantially to global morbidity and mortality. The peak age of onset of AUD is 18-24, thus a deeper understanding of the young adult experience is vital if we are to identify modifiable risk factors and intervene early in the developmental course of this disabling disorder. Critical unanswered questions include: How soon after drinking initiation do AUD symptoms begin to emerge? Which symptoms come first? Do the symptoms unfold in a predictable pattern? In what ways do the emerging symptoms interact with individual, peer, family and environmental risk factors to impact on the transition to disorder? The proposed RADAR study will examine the prospective development of AUD symptoms over the young adulthood (18-24) years. We will capitalise on an existing cohort of 1911 community-based adolescents who were recruited at age 13 and have completed a baseline and five annual follow-up assessments as part of an observational cohort study. We will interview these adolescents every 6 months between the ages of 19 and 23 to derive monthly histories of both alcohol use and AUD symptomatology, along with a comprehensive battery of risk and protective factor scales hypothesised to predict the emergence and course of AUD. The results of this study will inform the natural history of AUD and will be used to identify specific targets for prevention and early intervention of AUD. Ethical approval has already been granted for the study (UNSW HREC 10144). We will disseminate the results of the study through published manuscripts, conferences and seminar presentations.

    Early endoscopic recurrence is frequently observed in patients following resection for Crohn's disease (CD). However, factors affecting the incidence of an early postoperative endoscopic recurrence (EPER) have not been fully determined. The aim of this study was to evaluate risk factors for EPER after ileocolonic resection for CD. This was a retrospective, international multicentre study, in which 127 patients with a first ileocolonoscopy conducted between 6 and 12 months after ileocolonic resection for CD were included. Endoscopic recurrence was defined as a Rutgeerts score of ≥ i2. The following variables were investigated as potential risk factors for EPER: gender, age at surgery, location and behaviour of CD, smoking, concomitant perianal lesions, preoperative use of steroids, immunomodulators and biologics, previous resection, blood transfusion, surgical procedure (open vs laparoscopic approach), length of resected bowel, type of anastomosis (side-to-side vs end-to-end), postoperative complications, granuloma and postoperative biological therapy. Variables related to the patient, disease and surgical procedure were investigated as potential risk factors for EPER, with univariate and multivariate (logistic regression) analyses. 43/127 (34%) patients had EPER at the time of the first postoperative ileocolonoscopy. In univariate analysis, only preoperative steroid use was significantly associated with a higher rate of EPER [21/45 patients (47%) on steroids and 22/82 patients (27%) without steroids (P = 0.04)]. In multivariate analysis, only preoperative steroid use was a significant independent risk factor for EPER (odds ratio 3.28, 95% confidence interval: 1.30-8.28; P = 0.01). This study found that only preoperative steroid use was a significant risk factor for EPER after ileocolonic resection for CD. Prospective studies are necessary to evaluate precisely the impact of perioperative medications on EPER rates. Colorectal Disease © 2016 The Association

    To provide a survey of disease activity in patients treated with standard care in Italian clinical practice. This was an observational prospective cohort study in patients with early, aggressive rheumatoid arthritis (RA; duration ≤2 years but ≥6 weeks; DAS28 >3.2) naïve to anti-tumour necrosis factor (TNF) therapy who were treated with disease-modifying anti-rheumatic drugs (DMARDs) and/or biologics according to standard practice at 15 Italian ARPA (Artrite Reumatoide Precoce Aggressiva) centres. Patients were evaluated at baseline and after 6, 12 and 24 months. The primary endpoint was the proportion of patients achieving remission, as defined by disease activity score in 28 joints (DAS28) <2.6, after 1 year. Among the 152 patients enrolled, 92 were evaluable after 1 year and 77 after 2 years for DAS28. At baseline, patients had a mean DAS28 of 6.1±1.0. At 12 months, 62.6% of patients were treated with DMARDs (in monotherapy or in combination), and 37.4% with anti-TNFs (in monotherapy or in association with DMARDs). At 24 months, 35.1% were receiving anti-TNF therapy. The rate of DAS28 remission rates at 12 months and 24 months were 28.3% (95% confidence interval [CI] 19.1-37.5) and 41.6% (95% confidence interval [CI] 30.6-52.6), respectively. The remission rate was lower at 12 months compared with previous large randomised clinical trials for early, aggressive RA, but significantly improved at 24 months. These results suggest that patients in real-world clinical settings in Italy may experience a delay in receiving the best possible care.

    Objective: To investigate the effects of IL-6 and its receptors on bone loss in healthy women, and to assess the pathogenesis of the postmenopausal osteoporosis in women. Methods: One hundred and thirty one healthy women aged 31-72 including 64 sexual maturity women aged 31-52 were enrolled in four groups and 67 postmenopausal women, the years of menopause from 1 month to 23 years, were also enrolled in four groups. The bone mass of the lumbar-spine and femur were measured using dual-energy X-rays absorptiometry; the serum E 2 , FSH, BGP by radioimmunoassay (RIA); the serum IL-6, sIL-6R, sgp 130 by ELISA; the serum AKP, calcium, phosphate by auto-biochemistry instrument. Results: The BMD of lumbar-spine and right femur decreased following increase of age and the duration of menopause. Significant positive correlation was observed between BMD and E 2 . The serum IL-6, sIL-6R, sgp 130 level was low, and stable before menopause. The level of IL-6, sIL-6R, sgp 130 increased with variation of age and the duration of menopause. Significant negative correlation was observed between IL-6, sIL-6R, sgp 130 and E 2 , BMD. Serum AKP and BGP level was higher in postmenopausal women than that in sexual maturity women. The serum calcium level increased significantly soon after menopausal, then decreased to the normal level. The serum phosphate level had no difference in these groups. Conclusion: The main cause of postmenopausal osteoporosis is the unbalance of the bone formation and resorption

    Full Text Available Objective: To identify the prevalence of osteoporosis in postmenopausal women who conducted their examinations of Bone Mineral Densitometry in private clinic in the city of Maringá (PR in the years of 2012 and 2013 and their association with risk factors. Methods: This transversal, descriptive exploratory study involving 177 postmenopausal women. The study included patients who presented primary osteoporosis, with or without hysterectomy and excluded volunteers who presented other conditions or diseases associated with altered bone mass. The main analyzed variables were: race; Body Mass Index; ages of menarche and menopause and menopause time. Results: The average age of the sample was 59 years old with a standard deviation of ±7.97 years. In relation to the classification of the patients according to the results of the examination of bone mass, 23% were in the normal group, 65% presented osteopenia and 12%, osteoporosis. Statistical analysis showed association of advanced age and time of menopause with the disease, but there was no statistical significance in relation to the analysis for association of other risk factors. Conclusions: The study conducted allows to conclude that there was a low prevalence of normal densitometry and high prevalence of low bone mass in the sampling population. The age and menopausal time period can be considered as risk factors for osteoporosis in the sample.

  7. Bone remodeling in post-menopausal osteoporosis.

    Science.gov (United States)

    Lerner, U H

    2006-07-01

    Bone mass in the skeleton is dependent on the coordinated activities of bone-forming osteoblasts and bone-resorbing osteoclasts in discrete bone multi-cellular units. Remodeling of bone in these units is important not only for maintaining bone mass, but also to repair microdamage, to prevent accumulation of too much old bone, and for mineral homeostasis. The activities of osteoblasts and osteoclasts are controlled by a variety of hormones and cytokines, as well as by mechanical loading. Most importantly, sex hormones are very crucial for keeping bone mass in balance, and the lack of either estrogen or testosterone leads to decreased bone mass and increased risk for osteoporosis. The prevalence of osteoporotic fractures is increasing dramatically in the Western part of the world and is a major health problem in many countries. In the present review, the cellular and molecular mechanisms controlling bone remodeling and the influence of sex hormones on these processes are summarized. In a separate paper in this issue, the pathogenesis of post-menopausal osteoporosis will be compared with that of inflammation-induced bone remodeling, including the evidence for and against the hypothesis that concomitant post-menopausal osteoporotic disease influences the progression of periodontal disease.

    Full Text Available Background and Aim: It has been suggested that osteoporosis may be a predisposing factor for periodontitis and tissue destruction, thus periodontitis and mandibular bone density might be related. The purpose of the present study was to evaluate the clinical signs of periodontal tissue destruction in postmenopausal women. Materials and Methods: In this cross-sectional study, 60 postmenopausal women (51 to 78 years of age underwent radiographic examination of the right mandibular premolar. Mandibular bone density (MBD was measured using optical densitometry. Periodontal status variables examined included: probing pocket depth (PPD, clinical attachment level (CAL, bleeding on probing (BOP and plaque index (PLI. Data were analyzed by statistical tests using P<0.05 as the limit of significance. Results: This study found no statistically significant association between the four indicators of periodontal disease and mandibular bone density, but there was statistically significant association between mandibular bone density and the number of remaining teeth. There was also statistically significant association between PPD and the number of remaining teeth. Conclusion: These findings suggest that individuals with high MBD seem to retain teeth with deep periodontal pockets more easily than those with lower MBD.

    As endpoints of the hierarchical mass-assembly process, the stellar populations of local early-type galaxies encode the assembly history of galaxies over cosmic time. We use Horizon-AGN, a cosmological hydrodynamical simulation, to study the merger histories of local early-type galaxies and track how the morphological mix of their progenitors evolves over time. We provide a framework for alleviating `progenitor bias' - the bias that occurs if one uses only early-type galaxies to study the progenitor population. Early types attain their final morphology at relatively early epochs - by z ˜ 1, around 60 per cent of today's early types have had their last significant merger. At all redshifts, the majority of mergers have one late-type progenitor, with late-late mergers dominating at z > 1.5 and early-early mergers becoming significant only at z types is actually in progenitors with early-type morphology, while, at z ˜ 2, studying only early types misses almost all (80 per cent) of the stellar mass that eventually ends up in local early-type systems. At high redshift, almost all massive late-type galaxies, regardless of their local environment or star formation rate, are progenitors of local early-type galaxies, as are lower mass (M⋆ types as long as they reside in high-density environments. In this new era of large observational surveys (e.g. LSST, JWST), this study provides a framework for studying how today's early-type galaxies have been built up over cosmic time.

    Full Text Available Clostridium perfringens is an anaerobic gram positive rod that is found in normal vaginal and cervical flora in 1–10% of healthy women. Uterine infection with Clostridium perfringens is seen rarely but is often related to underlying uterine pathology and can progress quickly to sepsis. Early recognition of sepsis, prompt treatment with antibiotics, and source control with surgical management allow for optimal chance of recovery. We present a case of a postmenopausal woman who presented with sepsis, vaginal bleeding, and back pain who was found to have Clostridium perfringens infection in the setting of undifferentiated uterine sarcoma.

    Recent tsunami warning systems has equipped with vertically placed point-transducers for measuring surface level of water. However, they are capable for secondary or more after current stages of changing water mass directions by driven tectonic forces. Secondly, they are efficient on continent shelves about increasing wave-amplitude and stuck mass of water. Atmospheric pressure and wind velocity measurements provide auxiliary correction for eliminate wrong alerts. Deep ocean bed and sediment-water interface area is one of the best observational zone about primary water currents due to fault movements. Reverse or normal fault mechanism earthquakes may give only a short time for tsunami escape even with the help of coastal tsunami alert centres. However, we can save more time with observation of suspended or semi-placed particles at the oceanic-bed with parallel-array sensors, which are more efficient than a single transducer during an earthquake or any slow deformation stage of basin. Because one or more far transducers cannot be able to get information about particle dimensions and density clouds, for example, how fast they are at low velocities (e.g. in the order of 1 mm per second) during acceleration of water masses under tectonic forces. At faster velocities, linear-array transducer series are more efficient since they are even sensitive to their neighbour-sensor scanning areas. Because triangular scanning area of an individual sensor expands to its neighbour areas and it receives sound-beam reflections coming back from the same particle. Homogenously separated piezo-crystal structure provides a hammer effect with less trigger-energy under high-pressure. The experiences about high velocity (up to 1 m per second) and very-close particle observations were successful at a close-water circuit prepared by using 5 cm diameter pipe-pomp system. Observation supports earthquake early warning variety work about concentration of radon gas, free ions, magnetic field and

    We combine new high sensitivity ultraviolet (UV) imaging from the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) with existing deep HST/Advanced Camera for Surveys optical images from the Great Observatories Origins Deep Survey (GOODS) program to identify UV-dropouts, which are Lyman break galaxy (LBG) candidates at z ≅ 1-3. These new HST/WFC3 observations were taken over 50 arcmin 2 in the GOODS-South field as a part of the Early Release Science program. The uniqueness of these new UV data is that they are observed in three UV/optical (WFC3 UVIS) channel filters (F225W, F275W, and F336W), which allows us to identify three different sets of UV-dropout samples. We apply Lyman break dropout selection criteria to identify F225W-, F275W-, and F336W-dropouts, which are z ≅ 1.7, 2.1, and 2.7 LBG candidates, respectively. We use multi-wavelength imaging combined with available spectroscopic and photometric redshifts to carefully access the validity of our UV-dropout candidates. Our results are as follows: (1) these WFC3 UVIS filters are very reliable in selecting LBGs with z ≅ 2.0, which helps to reduce the gap between the well-studied z ∼> 3 and z ∼ 0 regimes; (2) the combined number counts with average redshift z ≅ 2.2 agree very well with the observed change in the surface densities as a function of redshift when compared with the higher redshift LBG samples; and (3) the best-fit Schechter function parameters from the rest-frame UV luminosity functions at three different redshifts fit very well with the evolutionary trend of the characteristic absolute magnitude, M*, and the faint-end slope, α, as a function of redshift. This is the first study to illustrate the usefulness of the WFC3 UVIS channel observations to select z ∼< 3 LBGs. The addition of the new WFC3 on the HST has made it possible to uniformly select LBGs from z ≅ 1 to z ≅ 9 and significantly enhance our understanding of these galaxies using HST sensitivity and resolution.

    Near-surface turbulence data from the Mountain Terrain Atmospheric Modeling and Observations (MATERHORN) program are used to study countergradient heat fluxes through the early evening transition. Two sites, subjected to similar large-scale forcing, but with vastly different surface and sub-surface characteristics, are considered. The Playa site is situated at the interior of a large dry lakebed desert with high sub-surface soil moisture, shallow water table, and devoid of vegetation. The Sagebrush site is located in a desert steppe region with sparse vegetation and little soil moisture. Countergradient sensible heat fluxes are observed during the transition at both sites. The transition process is both site and height dependent. At the Sagebrush site, the countergradient flux at 5 m and below occurs when the sign change of the sensible heat flux precedes the local temperature gradient sign change. For 10 m and above, the countergradient flux occurs when the sign change of the sensible heat flux follows the local temperature gradient sign change. At the Playa site, the countergradient flux at all tower levels occurs when the sign change of the sensible heat flux follows the local temperature gradient sign change. The phenomenon is explained in terms of the mean temperature and heat-flux evolution. The temperature gradient sign reversal is a top-down process while the flux reversal occurs nearly simultaneously at all heights. The differing countergradient behaviour is primarily due to the different subsurface thermal characteristics at the two sites. The combined high volumetric heat capacity and high thermal conductivity at the Playa site lead to small vertical temperature gradients that affect the relative magnitude of terms in the heat-flux tendency equation. A critical ratio of the gradient production to buoyant production of sensible heat flux is suggested so as to predict the countergradient behaviour.

    The aim was to investigate whether the sleep practices in early childhood education (ECE) settings align with current evidence on optimal practice to support sleep. Internationally, scheduled sleep times are a common feature of daily schedules in ECE settings, yet little is known about the degree to which care practices in these settings align with the evidence regarding appropriate support of sleep. Observations were conducted in 130 Australian ECE rooms attended by preschool children (Mean=4.9years). Of these rooms, 118 had daily scheduled sleep times. Observed practices were scored against an optimality index, the Sleep Environment and Practices Optimality Score, developed with reference to current evidence regarding sleep scheduling, routines, environmental stimuli, and emotional climate. Cluster analysis was applied to identify patterns and prevalence of care practices in the sleep time. Three sleep practices types were identified. Supportive rooms (36%) engaged in practices that maintained regular schedules, promoted routine, reduced environmental stimulation, and maintained positive emotional climate. The majority of ECE rooms (64%), although offering opportunity for sleep, did not engage in supportive practices: Ambivalent rooms (45%) were emotionally positive but did not support sleep; Unsupportive rooms (19%) were both emotionally negative and unsupportive in their practices. Although ECE rooms schedule sleep time, many do not adopt practices that are supportive of sleep. Our results underscore the need for education about sleep supporting practice and research to ascertain the impact of sleep practices in ECE settings on children's sleep health and broader well-being.

    Socially disinhibited or indiscriminate behavior (IB) has traditionally been investigated using caregiver reports. More recently, an observational measure based on the Strange Situation Procedure (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978), the Rating of Infant and Stranger Engagement (RISE; C. Riley, A. Atlas-Corbett, & K. Lyons-Ruth, 2005), was validated in home-reared at-risk children. The present study aimed to validate the RISE in an institutionally reared sample using the caregiver report, to assess whether IB assessed with the RISE was elevated among the institutionalized children, and to explore potential risk factors associated with IB. The study was conducted among 74 institutionalized toddlers aged 11 to 30 months. Sociodemographic questionnaires were used to assess pre-admission experiences, and aspects of institutional placement were coded from the children's files in the institution and staff's report. Institutionalized children displayed high frequencies of IB as assessed on the RISE, and this instrument was validated against caregiver report. Pre-admission experiences of the institutionalized children in their biological families-namely, prenatal risk and maternal emotional neglect risk-predicted IB. Results suggest that the RISE is adequate to use among institutionally reared toddlers and point to aspects of the early familial environment that may be implicated in IB.

    Full Text Available Background: Osteoporosis is particularly high in females, the early identification of which remains a challenge. Panoramic radiographs are routinely advised to detect periodontal diseases and can be used to predict low bone mineral density (BMD. Hence, this investigation was aimed to identify the risk of osteoporosis in pre- and postmenopausal periodontally healthy and chronic periodontitis women with digital panoramic radiographs. Materials and Methods: The study population consisted of 120 patients equally divided as Group I - Premenopausal periodontally healthy, Group II - Premenopausal periodontitis, Group III - Postmenopausal periodontally healthy, and Group IV - Postmenopausal periodontitis. Clinical parameters were recorded, and digital panoramic radiographs were used to record the mental index (MI, panoramic mandibular index (PMI, and mandibular cortical index (MCI scores. Results: MI was found to be varied, and the differences were highly significant among Group III and IV (P = 0.0003 and Group II and IV (P = 0.0007, and significant difference was found between Group I and Group II (P = 0.0113. MCI evaluation showed a greater prevalence of C2 and C3 patterns among postmenopausal women. MCI correlation with MI (P < 0.0001, PMI (P < 0.0001 and age (P = 0.0029 indicated a highly significant variance. Conclusion: The positive association between MCI and chronic periodontitis in postmenopausal women confirms the high risk of osteoporosis in them. Furthermore, an increased percentage of patients with undetected decrease in BMD may be identified by screening with digital panoramic radiographs which are done on a routine basis for periodontal and other dental diseases and thus could be used as an effective aid to quantify bone density in future.

    Abnormal uterine bleeding is the Common presenting complaint in Gynaecology Outpatient Department in all age groups. It is due to the anovulatory cycles which are commonly seen in adolescent and peri-menopausal women. Abnormal uterine bleeding is caused by wide variety of organic or non-organic causes. Histopathological examination of endometrial sample remains the gold standard for diagnosis of endometrial pathology. To study the clinicopathological spectrum of endometrium in abnormal uterine bleeding in peri-menopausal and post-menopausal age groups. The study included prospective analysis of 119 cases of endometrial samples in patients of abnormal uterine bleeding above 40 years of age. The specimens were routinely processed and H&E stained slides were studied. Patients were categorized into peri-menopausal (40-49 years) and post-menopausal (> 50 years) age group. A total of 119 specimens of endometrium were analyzed. Maximum number (73.94%) of cases were from peri-menopausal age group. The most common presenting complaint was menorrhagia (48.86%) followed by post-menopausal bleeding (26.05%). In peri-menopausal age group proliferative endometrium (35.22%) was the predominant histopathological pattern followed by endometrial hyperplasia (23.86%). Atrophic endometrium (25.80%) was the most frequent finding followed by endometrial hyperplasia (19.35%) in post-menopausal age group. Three cases of endometrial carcinoma were reported in post-menopausal age group only. A thorough histopathological work up and clinical correlation is mandatory in cases of abnormal uterine bleeding above the age of 40 years to find out organic lesions. Careful screening can detect early cancer of endometrium which has excellent prognosis and it will help in further management.

    To assess the efficacy and safety of intravaginal estriol administration on urinary incontinence, urogenital atrophy, and recurrent urinary tract infections in postmenopausal women. Eighty-eight postmenopausal women with urogenital aging symptoms were enrolled in this prospective, randomized, placebo-controlled study. Participants were randomly divided into two groups, with each group consisting of 44 women. Women in the treatment group received intravaginal estriol ovules: 1 ovule (1 mg) once daily for 2 weeks and then 2 ovules once weekly for a total of 6 months as maintenance therapy. Women in the control group received inert placebo vaginal suppositories in a similar regimen. We evaluated urogenital symptomatology, urine cultures, colposcopic findings, urethral cytologic findings, urethral pressure profiles, and urethrocystometry before as well as after 6 months of treatment. After therapy, the symptoms and signs of urogenital atrophy significantly improved in the treatment group in comparison with the control group. Thirty (68%) of the treated participants, and only seven (16%) of the control participants registered a subjective improvement of their incontinence. In the treated participants, we observed significant improvements of colposcopic findings, and there were statistically significant increases in mean maximum urethral pressure, in mean urethral closure pressure as well as in the abdominal pressure transmission ratio to the proximal urethra. Urethrocystometry showed positive but not statistically significant modifications. Our results show that intravaginal administration of estriol may represent a satisfactory therapeutic choice for those postmenopausal women with urogenital tract disturbances who have contraindications or refuse to undergo standard hormone therapy.

    Full Text Available Introduction: Inadequate vitamin D level is associated with altered bone turnover and bone loss, which increases the fracture risk. Aim: To assess the seasonal prevalence of inadequate (insufficient or deficient serum vitamin D levels in community-dwelling postmenopausal Polish women screened for osteoporosis. Material and methods : A cross-sectional observational study based on the regional urban non-institutionalized sample (n = 107 of postmenopausal Caucasian women in the age range of 51-83 years, not taking any medication and free from any condition likely to affect vitamin D status or calcium/bone metabolism. The outcome measures were the mean 25-OH vitamin D level across all the seasons and the percentage of vitamin D deficiency and insufficiency and defined as < 20 ng/dl (50 nmol/l and 20-30 ng/dl (50-75 nmol/l, respectively. Results: No statistically significant difference has been found in the mean vitamin D level, regardless of the season (p = 0.4. The prevalence of vitamin D deficiency and insufficiency were in spring 54% and 32%, in summer 46% and 46%, in autumn 67% and 27%, and in winter 61% and 22%, respectively. Conclusions : Vitamin D inadequacy is common in a sample of Polish community-dwelling postmenopausal women regardless of the season.

    This work aimed at assessing association between cardiovascular risk (CVR) and lycopene intake in pre- and post-menopausal women, as well as its correlation with LDL-C and HDL-C values and waist circumference (WC). A transversal design of comparison and correlation was carried out for independent samples. A 316 women (40-65 y) sample attending nutritional consultation at a Research Foundation for Endocrino Metabollic Diseases in Buenos Aires city (2005-2007) was randomized according to biological stage (35.8% premenopausal and 64.2% postmenopausal women). CVR was obtained based on Framingham Score and lycopene intake (source food and all lycopene containing food) according to weekly consumption frequency (mg/d and weekly/servings). Association between variables was calculated with the Student Test, Fisher Test and Pearson Correlation Coefficient (alpha significance level: 0.05). At both biological stages and for each CVR category, an inverse relationship was observed with lycopene intake, but only in premenopausal women with low CVR (Category III), lycopene intake was significantly greater than in those women who had moderate CVR (Category II). There was a significant correlation in postmenopausal women between LDL-C values and lycopene intake supplied by source food. However, in both biological stages a significant correlation was found between LDL-C values and all lycopene containing food consumption. No significant correlation was found between lycopene intake, HDL-C values and WC. These findings point out the relevances of a preventive nutritional approach at woman's different biological stages.

    Previous studies showed an inconsistent association of fruit and vegetable consumption with bone health. We assessed the associations in Chinese adolescents, young and postmenopausal women. A cross-sectional study conducted in China during July 2009 to May 2010. Bone mineral density (BMD) and content (BMC) at the whole body, lumbar spine and left hip were measured with dual-energy X-ray absorptiometry. Dietary intakes were assessed using an FFQ. All these values were separately standardized into Z-scores in each population subgroup. One hundred and ten boys and 112 girls (11-14 years), 371 young women (20-34 years, postpartum within 2 weeks) and 333 postmenopausal women (50-70 years). After adjustment for potential covariates, analysis of covariance showed a significantly positive association between fruit intake and BMD and BMC in all participants combined (P-trend: bottom tertile of fruit intake (all P intake and bone mass at all bone sites studied except for total body BMD (P = 0.030). Relatively more pronounced effects were observed in boys and postmenopausal women. Our findings add to the existing evidence that fruits and vegetables may have a bone sparing effect.

    Chronic pain is the main symptom of postmenopausal osteoporosis. This can decrease mobility and quality of life of the patients. The hypothesis of this study was that administration of an adjuvant pain medication is essential additionally to the basic therapy. The second question was if a recommendation can be formulated whether a peripheral or a central acting pain medication is more effective to prevent osteoporosis induced chronic pain. Three pseudorandomised patient groups were prospectively compared. Group 1 was treated with alendronate, vitamin D, and calcium. Group 2 also received ibuprofen, and group 3 also received tramadol. In 117 women suffering from postmenopausal osteoporosis, quality of life was measured before and 26 weeks after therapy using the International Osteoporosis Foundation Qualeffo-41 score, and pain intensity was measured using a visual analogue scale. No therapy-associated complications were observed during the study. After 26 weeks, quality of life significantly increased in groups 2 and 3 compared with group 1 (posteoporosis-associated chronic pain better than a centrally acting pain medication such as tramadol. It therefore can be recommended to prescribe ibuprofen rather than tramadol for treating osteoporosis-associated chronic pain in postmenopausal women if the specific risk for gastrointestinal side effects is considered.

    Full Text Available Acute abdomen with hemoperitoneum is a very rare entity in postmenopausal women due to gynecologic conditions. A 54-year-old, postmenopausal woman was brought to emergency department with severe abdominal pain. Physical examination revealed acute abdomen findings with 15 cm pelvic mass on the right adnexal region. Immediate exploratory laparotomy was performed. During laparotomy 1000 cc of bloodstained fluid, ruptured and actively bleeding large mass arising from right ovary was observed. Right salpingo-oopherectomy was performed in emergency conditions, and pathology report revealed an adult type of granulosa cell tumor. After this result, staging surgery was performed and patient was diagnosed as granulosa cell tumor stage 1 c. Cisplatin, etoposide, and bleomycin chemotherapy was given. Clinicians should be aware of granulosa cell tumors which may occur at any age and prone to rupture. Frozen section will be helpful in order to avoid incomplete surgeries especially in postmenopausal women presented with intra-abdominal bleeding.

    Frequent mood and sleep disorders and increased appetite leading to obesity are observed in postmenopausal women. Due to the limitations of hormone replacement therapy the researchers look for other treatment regimes. The aim of the study was to evaluate the efficacy of fluoxetine and melatonin in the treatment of these disorders. The study included 64 overweight postmenopausal women, aged 54 - 65 years, with increased appetite. They were randomly assigned in 2 groups. In group I (n = 30) fluoxetine (20 mg in the morning) and placebo (in the evening) were administered for 24 weeks. Group II (n = 34) received fluoxetine (20 mg in the morning) and melatonin (5 mg in the evening) in the same period of time. Hamilton anxiety rating scale (HARS), Beck depression scale (BDI), the insomnia severity index (ISI) and body mass index (BMI) were used to assess the health status and the treatment efficacy. After 24 weeks, comparable and statistically significant reduction in the level of anxiety and depression was obtained in both groups. In group I, the ISI decreased from 14.9 ± 2.5 points to 10.9 ± 1.9 points (P melatonin was useful option to treat mood, sleep and appetite disorders in postmenopausal women.

    Declines in ovarian function in postmenopausal women may contribute to increase inflammatory cytokines, which can lead to chronic diseases. However, studies have shown that exercise interventions are important to manage inflammatory conditions. Thus, the objective of this study was to analyze the effect of exercise intervention on inflammatory markers among obese and postmenopausal women. 70 women composed the sample (Exercise group [EG; n = 35] and nonexercise group [nEG; n = 35]). IL-6, TNF-α, and IL-10 were the inflammatory markers analyzed. Exercise program was 20 weeks long and consisted of aerobic and neuromuscular training. Data about chronic diseases, medication use, dietary intake, body composition and biochemical variables were collected. EG showed significant reductions in body mass index, waist circumference and body fat percentage, as well as increased lean body mass. EG showed significant reductions in TNF-α and significant interaction between group and intervention time. Reductions in IL-10 were identified only in nEG. Substantial effect of exercise intervention was observed with increased ratio of IL-10/IL-6 and IL-10/TNF-α. Combination of aerobic exercise and resistance training was effective in reducing inflammation. Thus, implementation and maintenance of similar exercise programs can contribute to reduce chronic inflammation among obese postmenopausal women.

    Abstract Postmenopausal osteoporosis is an important metabolic bone disease characterized by rapid bone loss occurring in the postmenopausal period. Recently, the most prevalent form of clinically significant osteopenia and osteoporosis involves various inflammatory conditions. The aim of the study is to evaluate the association between proinflammatory markers (interleukin [IL]-1β, IL-6, TNF-α) with bone turnover markers (BTMs) in postmenopausal Saudi women with and without osteoporosis. A total of 200 postmenopausal Saudi women ≥50 years old, 100 with osteoporosis and 100 without osteoporosis (control) were recruited under the supervision of qualified physicians in King Salman Hospital and King Fahd Medical City, Riyadh, Saudi Arabia. Serum tumor necrosis factor alpha (TNF-α), IL-1, IL-4, IL-6, and parathyroid hormone (PTH) were determined using Luminex xMAP technology. N-telopeptides of collagen type I (NTx) was assessed using ELISA, 25(OH) vitamin D and osteocalcin were determined using electrochemiluminescence, serum calcium and inorganic phosphate (Pi) were measured by a chemical analyzer. Serum IL-1β, IL-6, NTx, and PTH levels in women with osteoporosis were significantly higher than controls. Although IL-4 and osteocalcin were significantly lower than controls. IL-1β and TNF-α were positively associated with NTx in osteoporosis women. TNF-α, IL-6, and TNF-α were positively correlated with IL-lβ in both groups. A significant negative correlation between osteocalcin and IL-1β in healthy women and women with osteoporosis were observed. Findings of the present study implicate a role for cytokine pattern-mediated inflammation in patients with osteoporosis. PMID:28121926

    To find out whether or not soy milk as a phytoestrogen product can improve the quality of life of the Iranian postmenopausal women. Participants of this randomized clinical trial were 57 healthy postmenopausal women. All eligible women were randomly divided into two groups of soy milk (SG) and control (CG). Individuals in the SG (n = 34) received 500 ml soy milk including genistein (28.86 mg/dl) and daidzein (8.25 mg/dl) per day, while the participants in the CG (n = 23) received 500 ml low fat cow milk per day during 8 months. Both groups also took daily calcium-D capsules (500 mg calcium and 200 IU D3). The quality of life of all participants was examined twice (at the baseline and the end of the eighth month) using the menopause-specific quality of life (MENQOL) questionnaire. A total of 57 healthy postmenopausal women with a mean age of 52.13 (3.05) years were included in this study. Despite the significant but weak difference was observed between SG and CG in the sexual domain score (the mean of percent change: 0.46% vs. 33.94%, respectively; p = 0.031), while significant relationship was found between the soy milk consumption and improvement in the domains studied (vasomotor, psychosocial and physical). Overall our findings showed that soy milk does not improve the quality of life in postmenopausal women. But to achieve more reliable results, it is recommended further study to be done with a larger sample size, more prolonged, and with participants having severer vasomotor symptoms.

    Full Text Available Abstract Background In many mammals, the duration of the nocturnal melatonin elevation regulates seasonal changes in reproductive hormones such as luteinizing hormone (LH. Melatonin's effects on human reproductive endocrinology are uncertain. It is thought that the same hypothalamic pulse generator may both trigger the pulsatile release of GnRH and LH and also cause hot flashes. Thus, if melatonin suppressed this pulse generator in postmenopausal women, it might moderate hot flashes. This clinical trial tested the hypothesis that melatonin could suppress LH and relieve hot flashes. Methods Twenty postmenopausal women troubled by hot flashes underwent one week of baseline observation followed by 4 weeks of a randomized controlled trial of melatonin or matched placebo. The three randomized treatments were melatonin 0.5 mg 2.5–3 hours before bedtime, melatonin 0.5 mg upon morning awakening, or placebo capsules. Twelve of the women were admitted to the GCRC at baseline and at the end of randomized treatment for 24-hour sampling of blood for LH. Morning urine samples were collected twice weekly to measure LH excretion. Subjective responses measured throughout baseline and treatment included sleep and hot flash logs, the CESD and QIDS depression self-ratings, and the SAFTEE physical symptom inventory. Results Urinary LH tended to increase from baseline to the end of treatment. Contrasts among the 3 randomized groups were statistically marginal, but there was relative suppression combining the groups given melatonin as contrasted to the placebo group (p Conclusion The data are consistent with the hypothesis that melatonin suppresses LH in postmenopausal women. An effect related to the duration of nocturnal melatonin elevation is suggested. Effects of melatonin on reproductive endocrinology should be studied further in younger women and in men. Larger studies of melatonin effects on postmenopausal symptoms would be worthwhile.

    Osteoporosis is a common disease of the elderly, in which genetic and clinical factors contribute to the disease phenotype. Since the production of interleukin-1 (IL-1) has been implicated in the bone mass and skeletal disorders, we investigated whether IL-1 system gene polymorphisms are associated with the pathogenesis of osteoporosis in postmenopausal Taiwanese women.Osteoporosis is diagnosed by dual-energy x-ray absorptiometry, which measures bone mineral density (BMD) at multiple skeletal sites. We studied the IL-1a (-889C/T), IL-1 (-511C/T) and the 86 base pair variable number tandem repeat (VNTR) in intron 2 of the IL-1 receptor antagonist (IL-1ra) gene in 117 postmenopausal women with osteoporosis and 135 control subjects without a history of symptomatic osteoporosis. These gene polymorphisms were analyzed by polymerase chain reaction and restriction fragment length polymerase. Blood sugar and other risk factors were also determined.The frequencies of IL-1 (-511C/T) genotypes (P=.022, odds ratio=1.972) and alleles (P=.02, odds ratio=2.909) showed a statistically significant difference between the two groups. However, we did not find any statistically significant difference in IL-1 and IL-1ra polymorphisms (P>.05). We also observed a positive relationship between osteoporosis and cholesterol and a weak inverse relationship between blood sugar and osteoporosis in postmenopausal women.These experimental results suggest that the pathogenesis of osteoporosis is associated with IL-1 (-511C/T) polymorphism in postmenopausal women. This polymorphism is an independent risk factor for osteoporosis (Author).

    Dietary energy density (ED) is a measure of diet quality that estimates the amount of energy per unit of food (kilocalories per gram) consumed. Low-ED diets are generally high in fiber and fruits and vegetables and low in fat. Dietary ED has been positively associated with body mass index (BMI) and other risk factors for postmenopausal breast cancer. We evaluated the associations of total dietary ED and energy-dense (high-ED) foods with postmenopausal breast cancer incidence. Analyses included 56,795 postmenopausal women from the Cancer Prevention Study II Nutrition Cohort with no previous history of breast or other cancers and who provided information on diet, lifestyle, and medical history in 1999. Multivariable-adjusted breast cancer incidence rate ratios (RRs and 95% CIs) were estimated for quintiles of total dietary ED and for the consumption of high-ED foods in Cox proportional hazards regression models. During a median follow-up of 11.7 y, 2509 invasive breast cancer cases were identified, including 1857 estrogen receptor-positive and 277 estrogen receptor-negative tumors. Median dietary ED was 1.5 kcal/g (IQR: 1.3-1.7 kcal/g). After adjusting for age, race, education, reproductive characteristics, and family history, high compared with low dietary ED was associated with a statistically significantly higher risk of breast cancer (RR for fifth quintile compared with first quintile: 1.20; 95% CI: 1.05, 1.36; P-trend = 0.03). The association between the amount of high-ED foods consumed and breast cancer risk was not statistically significant. We observed no differences by estrogen receptor status or effect modification by BMI, age, or physical activity. These results suggest a modest positive association between total dietary ED and risk of postmenopausal breast cancer. © 2016 American Society for Nutrition.

    Osteoporosis and periodontitis are common diseases affecting post-menopausal women; however, the exact relationship between the diseases is still uncertain. The purposes of this study were to examine the periodontal status in a group of type I post-menopausal women with and without osteoporosis and to elucidate the possible role of the osteoporosis in the pathogenesis of periodontal disease. Thirty-four patients (18 in the osteoporotic and 16 in the non-osteoporotic group) were selected from 329 post-menopausal Taiwanese women who had completed radiographic measurements of spinal bone mineral density and received full-mouth periodontal examination. Periodontal measurements, including O'Leary plaque index, probing depths, clinical attachment level, and gingival recession, on 6 sites of each tooth of full mouth were examined and recorded by 1 examiner. Significantly greater probing depth was noted at the interproximal, but not at the facio-lingual, osteoporotic sites if compared to those non-osteoporotic sites. The depth was also significantly influenced by the examining factors of plaque accumulation, tooth location, and jaws. By individual jaw, increased attachment loss accompanied by greater probing depth and gingival recession was found at the osteoporotic sites on mandible if compared to non-osteoporotic sites. On maxilla, however, less gingival recession and attachment loss were observed at the osteoporotic sites. In the present study, increased attachment loss accompanied by greater probing depth and gingival recession was found at the osteoporotic sites on mandible. However, the parameters were also influenced by the examining factors of plaque accumulation, tooth location, and jaws. Therefore, we suggest that post-menopausal osteoporosis may play a role in the pathogenesis of periodontal disease, especially on the mandible, although the etiology of periodontal disease is still multi-factorial.

    The fat and bone connection is complicated, and the effect of adipose tissue on hip bone strength remains unclear. The aim of this study was to clarify the relative contribution of body fat accumulation and fat distribution to the determination of proximal femur strength in healthy postmenopausal Chinese women. This cross-sectional study enrolled 528 healthy postmenopausal women without medication history or known diseases. Total lean mass (LM), appendicular LM (ALM), percentage of lean mass (PLM), total fat mass (FM), appendicular FM (AFM), percentage of body fat (PBF), android and gynoid fat amount, android-to-gynoid fat ratio (AOI), bone mineral density (BMD), and proximal femur geometry were measured by dual energy X-ray absorptiometry. Hip structure analysis was used to compute some variables as geometric strength-related parameters by analyzing the images of the hip generated from DXA scans. Correlation analyses among anthropometrics, variables of body composition and bone mass, and geometric indices of hip bone strength were performed with stepwise linear regression analyses as well as Pearson's correlation analysis. In univariate analysis, there were significantly inverse correlations between age, years since menopause (YSM), hip BMD, and hip geometric parameters. Bone data were positively related to height, body weight, LM, ALM, FM, AFM, and PBF but negatively related to AOI and amount of android fat (all P hip bone strength was observed to have a consistent and unchanged positive association with AFM and a negative association with AOI, whereas its association with other variables of body composition was not significant after adjusting for age, years since menopause, height, body weight, and BMI. AFM may be a positively protective effect for hip bone strength while AOI, rather than android fat, shows a strong negative association with hip bone strength after making an adjustment for confounders (age, YSM, height, body weight, and BMI) in healthy

    Postmenopausal osteoporosis is an important metabolic bone disease characterized by rapid bone loss occurring in the postmenopausal period. Recently, the most prevalent form of clinically significant osteopenia and osteoporosis involves various inflammatory conditions. The aim of the study is to evaluate the association between proinflammatory markers (interleukin [IL]-1β, IL-6, TNF-α) with bone turnover markers (BTMs) in postmenopausal Saudi women with and without osteoporosis. A total of 200 postmenopausal Saudi women ≥50 years old, 100 with osteoporosis and 100 without osteoporosis (control) were recruited under the supervision of qualified physicians in King Salman Hospital and King Fahd Medical City, Riyadh, Saudi Arabia. Serum tumor necrosis factor alpha (TNF-α), IL-1, IL-4, IL-6, and parathyroid hormone (PTH) were determined using Luminex xMAP technology. N-telopeptides of collagen type I (NTx) was assessed using ELISA, 25(OH) vitamin D and osteocalcin were determined using electrochemiluminescence, serum calcium and inorganic phosphate (Pi) were measured by a chemical analyzer. Serum IL-1β, IL-6, NTx, and PTH levels in women with osteoporosis were significantly higher than controls. Although IL-4 and osteocalcin were significantly lower than controls. IL-1β and TNF-α were positively associated with NTx in osteoporosis women. TNF-α, IL-6, and TNF-α were positively correlated with IL-lβ in both groups. A significant negative correlation between osteocalcin and IL-1β in healthy women and women with osteoporosis were observed. Findings of the present study implicate a role for cytokine pattern-mediated inflammation in patients with osteoporosis.

    Worldwide studies, even in our country, have thrown discrepant results about the relation between osteoporosis, parity and age of menarche. To investigate the relation of osteoporosis in postmenopausal mexican women with multiparity and age of menarche. Transversal, retrospective and analytical study. Non-probabilistic sampling technique was performing with users women of the IMSS in San Luis Potosí. Reproductive history and age of menarche were obtained by the addition of these items to the previously validated Albrand questionnaire. Women were divided into groups according to the number of pregnancies in: normal parity (0 to 3 childbirths) conformed by 112 patients (46%) and multiparity (> or = 4 pregnancies), 131 women (54%). In relation to menarche with an average of 12.98 years, from this number we divided them in: early menarche (before the age of 13) and late menarche (at 13 years of age or after). It was measured bone mineral density with dual distal forearm x-ray absorptiometry to all patients. 243 women were studied, with an average of age of 55.92, rank 31 to 80 years. Using the criteria, of the World Health Organization, 18% of posmenopausal women had osteoporosis, 39% had osteopenia and 41% had bone normality. No association was found between the number of deeds and osteoporosis. Additionally we observed that the women who had 4 or more children were older than the other women. average 57.42 against 54.16. Also there was significant negative correlation (r = -0.43) between age and densitometry. In addition we found that an age greater to 13 years in the appearance of the menarche was related to osteoporosis (OR 4.46; p = 0.035). In posmenopausal women a menarche at the age of 13 years or after is a risk factor for osteoporosis.

    Dual-energy X-ray absorptiometry-based hip structural analysis was performed to evaluate the effect of a bisphosphonate, minodronic acid hydrate, on the geometry of the proximal femur in Japanese patients with osteoporosis. The subjects were 103 postmenopausal patients (average age 63.9 +/- 6.4 years) with primary osteoporosis. Minodronic acid hydrate was administered orally at a dose of 1 mg/day for 12 months. Significant early responses at 3-6 months after the start of administration were observed in all three regions of the proximal femur (narrow neck, intertrochanter, and shaft) in terms of bone density, geometry, and bone strength indices. The outcomes of therapy included a reduction of the internal diameter of the cortical bone (-0.1, -0.6, and -0.2% in the neck, intertrochanter, and shaft, respectively, at 12 months; not significant) and a significant increase in cortical thickness (3.1, 3.7, and 2.0% in the respective regions at 12 months). Furthermore, minodronic acid hydrate induced a significant enlargement of the cross-sectional bone area, which is related to compressive strength; a significant increase in cross-sectional moment of inertia and section modulus (SM 4.9, 5.8, and 2.9% in the neck, intertrochanter, and shaft, respectively, at 12 months; P < 0.001), which are related to the bending strength; and a significant reduction in buckling ratio (BR -3.0% (P < 0.001), -4.2% (P < 0.001), and -1.4% (P < 0.05) in the respective regions at 12 months), which reflects improved cortical stability. These findings show that minodronic acid hydrate reduces age-related endocortical bone resorption, leading to increased cortical thickness and sustained or enhanced bone strength.

Observational evidence of gravity-wave activity is provided by Atmospheric Infrared Sounder (AIRS radiances and infrared spectroscopic detection of nitric acid trihydrate (NAT in PSCs is obtained from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS. Goddard Earth Observing System Data Assimilation System (GEOS-5 DAS analyses are used to derive Lagrangian trajectories and to determine temperature-time histories of air parcels. We use CALIOP backscatter and depolarization measurements to classify PSCs and the MLS measurements to determine the corresponding gas-phase HNO3 as a function of temperature. For liquid PSCs the uptake of HNO3 follows the theoretical equilibrium curve for supercooled ternary solutions (STS, but at temperatures about 1 K lower as determined from GEOS-5. In the presence of solid phase PSCs, above the ice frost-point, the HNO3 depletion occurs over a wider range of temperatures (+2 to −7 K distributed about the NAT equilibrium curve. Rapid gas-phase HNO3 depletion is first seen by MLS from from 23–25 May 2008, consisting of a decrease in the volume mixing ratio from 14 ppbv (parts per billion by volume to 7 ppbv on the 46–32 hPa (hectopascal pressure levels and accompanied by a 2–3 ppbv increase by renitrification at the 68 hPa pressure level. The observed region of depleted HNO3 is substantially smaller than the region bounded by the NAT existence temperature threshold. Temperature-time histories of air parcels demonstrate that the depletion is more clearly correlated with prior exposure to temperatures a few kelvin above the frost-point. From the combined data we infer the presence

    Donor breastmilk (DBM) has gained popularity as an alternative to formula when mother's own milk (MOM) is unavailable. The objective of this study was to evaluate the effects of a predominantly DBM diet on growth and subsequent neurodevelopment in preterm infants at a level 3 neonatal intensive care unit (NICU). This single-center, observational cohort study compared data from preterm infants supplemented with predominantly (>50%) DBM to those from age- and weight-matched infants fed only MOM or supplemented with predominantly (>50%) preterm formula (PF). The primary outcome was in-hospital weight gain, and the secondary outcome was neurodevelopment, as assessed by the Bayley III scale at 1 and 2 years' corrected age. Exclusion criteria were major congenital defects, death prior to discharge from the NICU, or supplementation volumes of <50% over the first month of life. We compared the outcomes among the 3 feeding groups with the χ 2 test, ANOVA, and ANCOVA, with post hoc pairwise comparisons after adjustment for the following confounders: bronchopulmonary dysplasia, multiple births, and social work involvement. In the entire cohort, the mean gestational age was 27.1 weeks and the mean birthweight was 914 g. The DBM (n = 27) and PF (n = 25) groups were similar with regard to socioeconomic characteristics. DBM infants regained birthweight more slowly over the first month of life compared with infants fed MOM (n = 29) or PF (mean [SD], 17.9 [5.7], 22.0 [6.8], and 20.3 [5.7] g/kg/d, respectively; P = 0.05); however, this growth difference was attenuated at later time points. In a fully adjusted model, the DBM group scored significantly lower in cognition at both 1 year (P = 0.005) and 2 years (P = 0.03) of age compared with the infants fed non-DBM diets. The findings from this study suggest that in this NICU, preterm infants supplemented with predominantly DBM had compromised early in-hospital weight gain and, possibly, early cognitive delays compared with infants

    Osteoporosis is reported to be common among postmenopausal Saudi women. The reported incidence varies between 50-60%. Different machines were used to reach these conclusions. At present it is believed that dual energy x-ray absorptiometry (DEXA) is the most accurate method to diagnose osteoporosis. This study was conducted to measure bone mineral density (BMD) measurement of lumbar spine and the upper femur of Saudi postmenopausal women attending orthopedic clinic with unrelated complaints. This study comprises of 256 patients attending orthopedic clinics at King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia between January 2002 and June 2003. The data gathered was age, duration of menopause, height and weight for body mass index (BMI) calculation. Women with secondary osteoporosis were excluded from study. Patient's orthopedic complaints were also recorded in the database. Bone mineral density measurements were carried out using Hologic total body DEXA machine. The data were analyzed using SPSS package. The data of 256 patients was available for analysis. The average age of patients screened was 57.62 years (49-76) SD+-6.71. The BMI was 21.3-42.9 Kg/m (SD+-5.34). The BMD of lumbar spine was 0.785 gm/cm2 (0.527-1.023) SD +-0.142 and that of the hip region was 0.764 gm/cm2 (0.500-1.069) SD +-0.149. As per the WHO classification 59 women (23%) were classified as normal with the T score of -0.82, 78 (30.5%) as osteopenic with T score -2.5 and 119 (46.7%) as osteoporosis with T score -3.58. When the BMD of the hip was analyzed 62 (24.2%) were normal T score -1.0, 81 (31.6%) as osteopenic, T score -2.5 and 113 (44.1%0 as osteoporotic, with a T score of -3.1. on the basis of analysis of lumbar spine 190 (74.2%) had increased risk of fracture as compared to the analysis of hip 59% were at increased risk of fracture. Our results indicate that postmenopausal Saudi women suffer from osteoporosis and osteopenia higher than those from other parts of the

    to investigate the early pushing urge (EPU) incidence in one maternity unit and explore how it is managed by midwives. The relation to some obstetric outcomes was also observed but not analysed in depth. prospective observational study. Italian maternity hospital. 60 women (44 nullips and 16 multips) experiencing EPU during labour. the total EPU incidence percentage was 7.6%. The single midwives' incidences range had a very wide margin, noting an inverse proportion between the number of diagnoses of EPU and midwife's waiting time between urge to push and vaginal examination. Two care policies were adopted in relation to the phenomenon: the stop pushing technique (n=52/60) and the 'let the woman do what she feels' technique (n=8/60). In case of stop pushing techniques, midwives proposed several combined techniques (change of maternal position, blowing breath, vocalisation, use of the bath). The EPU diagnosis at less than 8cm of cervical dilatation was associated with more medical interventions. Maternal and neonatal outcomes were within the range of normal physiology. An association between the dilatation at EPU diagnosis and obstetric outcomes was observed, in particular the modality of childbirth and perineal outcomes. this paper contributes new knowledge to the body of literature around the EPU phenomenon during labour and midwifery practices adopted in response to it. Overall, it could be argued that EPU is a physiologic variation in labour if maternal and fetal conditions are good. Midwives might suggest techniques to woman to help her to stay with the pain, such as change of position, blowing breath, vocalisation and use of the bath. However, the impact of policies, guidelines and culture on midwifery practices of the specific setting are a limitation of the study because it is not representative of other similar maternity units. Thus, a larger scale work should be considered, including different units and settings. The optimal response to the phenomenon

    Osteoporosis is a gender-related disease that is especially prevalent in postmenopausal women. New drugs have been developed led by issues of interest and concerns about this disease, each one striving to be more effective and safer than the previous one. Bazedoxifene acetate is a new, third-generation, selective estrogen receptor modulator. This drug is used to treat postmenopausal osteoporosis in women with a high risk of fracture. Bazedoxifene acetate significantly prevents bone mass loss at 20 mg/day in healthy postmenopausal women with normal or low bone mineral density. The risk of vertebral fractures in women with osteoporosis was reduced by 42% (P menopause and a greater antiestrogen effect at the level of the uterus. This has made this compound an appropriate option in young postmenopausal women with osteoporosis and a risk of fractures. Copyright 2011 Prous Science, S.A.U. or its licensors. All rights reserved.

    The binding of human LH and human FSH to postmenopausal ovarian tissue from 21 patients with cervical carcinoma was analyzed. The binding sites for FSH and LH were demonstrated in postmenopausal ovarian tissue. The surface-binding sites for gonadotropins were localized in the cells of cortical stroma of the postmenopausal ovary. In addition, diffuse cytoplasmic staining of endogenous estrogen and 3 beta-hydroxysteroid dehydrogenase activity were detected immunohistochemically and histochemically in the cells of the cortical stroma. Electron microscopic study also suggested steroidogenic function in the cells of the cortical stroma. The results of the present study suggest that postmenopausal ovaries contain specific binding sites for pituitary gonadotropins and play a role in ovarian steroidogenesis.

    Objectives To investigate VTE risk in relation to age at menopause, age at menarche, parity, bilateral oophorectomy and time since menopause, as well as any interaction with randomized HT assignment among postmenopausal women. Methods Using pooled data from the Women’s Health Initiative HT clinical trials including 27,035 postmenopausal women ages 50 to 79 years with no history of VTE, we assessed the risk of VTE in relation to age at menopause, age at menarche, parity, bilateral oophorectomy and time since menopause by Cox proportional hazard models. Linear trends, quadratic relationships and interactions of reproductive life characteristics with HT on VTE risk were systematically tested. Results During the follow-up, 426 women reported a first VTE, including 294 nonprocedure-related events. No apparent interaction of reproductive life characteristics with HT assignment on VTE risk was detected and there was any significant association of VTE with age at menarche, age at menopause, parity, oophorectomy or time since menopause. However, analyses restricted to nonprocedure-related VTE showed a U-shaped relationship between age at menopause and thrombotic risk that persisted after multivariable analysis (pmenopause, those with early menopause (agemenopause (age>55 years) had a significant increased VTE risk (HR=1.8;95%CI:1.2–2.7 and HR=1.5;95%CI:1.0–2.4, respectively). Conclusion Reproductive life characteristics have little association with VTE and do not seem to influence the effect of HT on thrombotic risk among postmenopausal women. Nevertheless, early and late onset of menopause might be newly identified risk factors for nonprocedure-related VTE. PMID:23760439

    To investigate the correlation between postmenopausal osteoporosis (PMO) and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-)6, the receptor activator of nuclear factor- κB ligand (RANKL), and osteoprotegerin (OPG) and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    We examined the cross-sectional association of the intakes of different types of fishes with bone mass and osteoporosis risk in postmenopausal Chinese women. We found that higher intake of sea fish is independently associated with greater bone mass and lower osteoporosis risk among postmenopausal Chinese women. Fish contains many important nutrients that are beneficial on bone health, but limited data on the relationship between fish intake and bone health are available. We examined the association of the intakes of different types of fishes with bone mineral density (BMD) and bone mineral content (BMC) and osteoporosis risk. This population-based cross-sectional study was conducted among 685 postmenopausal Chinese women. Habitual dietary intakes were assessed using food frequency questionnaire. BMD and BMC at the whole body, lumbar spine, and left hip were measured with dual-energy x-ray absorptiometry. After adjusting for the potential confounders, we observed dose-dependent relations between sea fish intake and BMDs, BMCs, and osteoporosis risk; the mean BMDs were 3.2-6.8% higher, and BMCs 5.1-9.4% higher in the top quintile groups (Q5) of sea fish intake than in the bottom quintile (Q1) at the whole body and hip sites (p intake of sea fish is independently associated with greater bone mass and lower osteoporosis risk among postmenopausal Chinese women.

    Full Text Available Background: Osteoporosis and periodontitis have several risk factors in common. The majority of studies evaluating periodontal bone loss and systemic bone mineral density have found that low bone mineral density systemically is significantly associated with an increase in loss of alveolar bone height and periodontal destruction. Hence, the purpose of the study was to determine the effect of periodontitis on mandibular radiomorphometric indices, serum calcium and serum estradiol levels in postmenopausal women. Materials and Methods: Forty female patients in the age group of 35–55 years were included in the study. The participants were divided into two equal groups, i.e., control group A (twenty - postmenopausal women with healthy periodontium and study group B (twenty - postmenopausal women with periodontitis. A thorough clinical examination of all the forty patients was carried out to detect the presence of periodontitis on the basis of clinical attachment level. Quantitative indices were measured on digital panoramic radiographs, and serum calcium and estradiol levels were estimated. Results: No statistically significant correlation of periodontitis with any of the radiomorphometric indices, serum calcium and serum estradiol levels was observed in postmenopausal women. Conclusion: There is little evidence of correlation of serum estradiol, serum calcium levels, and morphometric indices with periodontitis and therefore detailed further research about this correlation is required.

    The widespread availability of effective antiretroviral therapy (ART) has transformed HIV from a life-limiting condition to one with near-normal life expectancy. HIV is associated with an increased risk of osteopenia and osteoporosis, with people living with HIV (PLHIV) potentially experiencing these conditions at a younger age than their HIV-negative counterparts. The mechanisms driving bone disease in HIV are complex and include: an increased prevalence of traditional risk factors; other comorbid conditions; and HIV-associated factors such as viral effects, systemic inflammation, and ART-related factors. One-third of PLHIV in the United Kingdom are female, and increasing numbers of women living with HIV (WLHIV) are reaching menopausal age. Oestrogen decline in the context of an elevated background risk of poor bone health results in WLHIV being at greater risk of osteoporosis than women without HIV. European HIV guidelines therefore recommend routine screening of postmenopausal WLHIV using FRAX © for clinical risk factors, with or without bone mineral density scanning. Data support the use of calcium and vitamin D supplementation, and bisphosphonates in the treatment of osteoporosis in PLHIV. Additionally, some patients with confirmed osteoporosis may benefit from a switch to an ART agent with a better bone safety profile. However, there remains a notable paucity of data on HIV and menopause, including the impact of hormone replacement therapy on the bone health of WLHIV. In conclusion, it is important that clinicians are aware that postmenopausal WLHIV are a group at particular risk of bone disease, who require proactive screening and advice about preventative measures.

    The neurodegenerative disorder Huntington's disease (HD) is typically characterized by extensive loss of striatal neurons and the midlife onset of debilitating and progressive chorea, dementia, and psychological disturbance. HD is caused by a CAG repeat expansion in the Huntingtin ( HTT ) gene, translating to an elongated glutamine tract in the huntingtin protein. The pathogenic mechanism resulting in cell dysfunction and death beyond the causative mutation is not well defined. To further delineate the early molecular events in HD, we performed RNA-sequencing (RNA-seq) on striatal tissue from a cohort of 5-y-old OVT73 -line sheep expressing a human CAG-expansion HTT cDNA transgene. Our HD OVT73 sheep are a prodromal model and exhibit minimal pathology and no detectable neuronal loss. We identified significantly increased levels of the urea transporter SLC14A1 in the OVT73 striatum, along with other important osmotic regulators. Further investigation revealed elevated levels of the metabolite urea in the OVT73 striatum and cerebellum, consistent with our recently published observation of increased urea in postmortem human brain from HD cases. Extending that finding, we demonstrate that postmortem human brain urea levels are elevated in a larger cohort of HD cases, including those with low-level neuropathology (Vonsattel grade 0/1). This elevation indicates increased protein catabolism, possibly as an alternate energy source given the generalized metabolic defect in HD. Increased urea and ammonia levels due to dysregulation of the urea cycle are known to cause neurologic impairment. Taken together, our findings indicate that aberrant urea metabolism could be the primary biochemical disruption initiating neuropathogenesis in HD.

    The Earth Observing One (EO-1) satellite was launched in November 2000 as a one year technology demonstration mission for a variety of space technologies. After the first year, it was used as a pathfinder for the creation of SensorWebs. A SensorWeb is the integration of variety of space, airborne and ground sensors into a loosely coupled collaborative sensor system that automatically provides useful data products. Typically, a SensorWeb is comprised of heterogeneous sensors tied together with a messaging architecture and web services. Disasters are the perfect arena to use SensorWebs. One SensorWeb pilot project that has been active since 2009 is the Namibia Early Flood Warning SensorWeb pilot project. The Pilot Project was established under the auspices of the Namibian Ministry of Agriculture Water and Forestry (MAWF)/Department of Water Affairs, the Committee on Earth Observing Satellites (CEOS)/Working Group on Information Systems and Services (WGISS) and moderated by the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER). The effort began by identifying and prototyping technologies which enabled the rapid gathering and dissemination of both space-based and ground sensor data and data products for the purpose of flood disaster management and water-borne disease management. This was followed by an international collaboration to build small portions of the identified system which was prototyped during that past few years during the flood seasons which occurred in the February through May timeframe of 2010 and 2011 with further prototyping to occur in 2012. The SensorWeb system features EO-1 data along with other data sets from such satellites as Radarsat, Terra and Aqua. Finally, the SensorWeb team also began to examine the socioeconomic component to determine the impact of the SensorWeb technology and how best to assist in the infusion of this technology in lesser affluent areas with low levels of basic

    In our previous articles (Chertok et al. in Solar Phys. 282, 175, 2013; Chertok et al. in Solar Phys. 290, 627, 2015), we presented a preliminary tool for the early diagnostics of the geoeffectiveness of solar eruptions based on the estimate of the total unsigned line-of-sight photospheric magnetic flux in accompanying extreme ultraviolet (EUV) arcades and dimmings. This tool was based on the analysis of eruptions observed during 1996 - 2005 with the Extreme-ultraviolet Imaging Telescope (EIT) and the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SOHO). Empirical relationships were obtained to estimate the probable importance of upcoming space weather disturbances caused by an eruption, which just occurred, without data on the associated coronal mass ejections. In particular, it was possible to estimate the intensity of a non-recurrent geomagnetic storm (GMS) and Forbush decrease (FD), as well as their onset and peak times. After 2010 - 2011, data on solar eruptions are obtained with the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO). We use relatively short intervals of overlapping EIT-AIA and MDI-HMI detailed observations, and additionally, a number of large eruptions over the next five years with the 12-hour cadence EIT images to adapt the SOHO diagnostic tool to SDO data. We show that the adopted brightness thresholds select practically the same areas of arcades and dimmings from the EIT 195 Å and AIA 193 Å image, with a cross-calibration factor of 3.6 - 5.8 (5.0 - 8.2) for the AIA exposure time of 2.0 s (2.9 s). We also find that for the same photospheric areas, the MDI line-of-sight magnetic flux systematically exceeds the HMI flux by a factor of 1.4. Based on these results, the empirical diagnostic relationships obtained from SOHO data are adjusted to SDO instruments. Examples of a post-diagnostics based on SDO data are presented. As before, the

    Postmenopausal women manifest emotional disorders associated with an increase in appetite. The aim of the study was to assess the serotonin and melatonin secretion and metabolism in postmenopausal women in relation to eating disorders. Sixty postmenopausal women and 30 women without hormonal disturbances were enrolled into the study and divided into three groups: group I (control) - women without menstrual disorders, group II - postmenopausal women without appetite disorders and change in body weight, and group III - postmenopausal women with increased appetite and weight gain. Serum melatonin, serotonin, urinary 6-sulfatoxymelatonin (aMT6s), and 5-hydroxyindoleacetic acid (5-HIAA) excretion were measured. Serum serotonin and melatonin levels in groups II and III were lower compared to group I. Urinary 5-HIAA and aMT6s excretion was lower in overweight women. In group III the correlation between the serum level of serotonin, melatonin, and BMI was negative; a high statistical significance was found between BMI and urinary aMT6s excretion. Melatonin supplementation and use of drugs modulating the serotonin homeostasis together with female hormones have a beneficial effect in complex treatment of disorders of eating in postmenopausal women.

    To know the osteoponia and osteoporosis prevalence in postmenopausal women determined with broadband ultrasonic attenuation (BUA). Descriptives cross-sectional study of prevalence. Salvador Allende Health Center. Valencia, Spain. A total of 115 postmenopausal women aged 49 at 85 years old was studied, initiated in September to December 2003. Iatrogenic menopause or women with calcium, vitamin D, estrogen replacement therapy, estrogen receptor modulators, and biphosphonates therapy were considered criteria for exclusion. We measured bone mineral density with BUA at right calcaneus. We analyzed the age, height, and weight, the result of BUA, tobacco and diuretics consumption and years of amenorrhea. . The prevalence of osteoporosis was 50.4%. Other 29.6% had osteopenia. Of the postmenopausal women with osteoporosis, 27.6% were 70 to 75 years old. The 82.8% of postmenopausal women with osteoporosis were younger than 75 years old. The 66.7% postmenopausal women with body mass index lesser than 25 had osteoporosis. The osteoporosis prevalence in our patients was greater than other studies (30%). Emphasis may be placed on screening osteoporosis with BUA in primary health care. We suggested that educational community programs should start at an earlier age to identify factors that contribute to maintaining bone mineral density among postmenopausal women.

    Knowledge about early innate immune responses at the mucosal surfaces of the female genital tract is important in understanding the pathogenesis of heterosexual transmission of human immunodeficiency virus type-1 (HIV-1). As estradiol decreases inflammatory responses, we postulated that an estradiol-deficient state such as post-menopause could enhance expression of inflammatory factors that stimulate HIV-1 replication. We compare HIV-1 integration, transcription, and viral p24 release levels among ectocervical tissues obtained from pre- and post-menopausal donors. We detected enhanced HIV-1 p24 release levels in post- compared with pre-menopausal tissues (Ppost-menopausal tissues exhibited levels of HIV-1 transcription above background compared with only 60% of pre-menopausal tissues. Increased HIV-1 transcription was associated with enhanced interleukin (IL)-1β, IL-6, monocyte chemotactic protein-1, growth-regulated oncogene-α, and interferon-γ-inducible protein-10 expression. Neutralization and nuclear factor-κB-targeting small-interfering RNA experiments both decreased HIV-1 transcription, suggesting that the early inflammatory response may facilitate HIV-1 replication in ex vivo ectocervical tissues from post-menopausal women.

    It is unknown if extremely early initiation of antiretroviral therapy (ART) may lead to long-term ART-free HIV remission or cure. As a result, we studied 2 individuals recruited from a pre-exposure prophylaxis (PrEP) program who started prophylactic ART an estimated 10 days (Participant A; 54-year-old male) and 12 days (Participant B; 31-year-old male) after infection with peak plasma HIV RNA of 220 copies/mL and 3,343 copies/mL, respectively. Extensive testing of blood and tissue for HIV persistence was performed, and PrEP Participant A underwent analytical treatment interruption (ATI) following 32 weeks of continuous ART. Colorectal and lymph node tissues, bone marrow, cerebral spinal fluid (CSF), plasma, and very large numbers of peripheral blood mononuclear cells (PBMCs) were obtained longitudinally from both participants and were studied for HIV persistence in several laboratories using molecular and culture-based detection methods, including a murine viral outgrowth assay (mVOA). Both participants initiated PrEP with tenofovir/emtricitabine during very early Fiebig stage I (detectable plasma HIV-1 RNA, antibody negative) followed by 4-drug ART intensification. Following peak viral loads, both participants experienced full suppression of HIV-1 plasma viremia. Over the following 2 years, no further HIV could be detected in blood or tissue from PrEP Participant A despite extensive sampling from ileum, rectum, lymph nodes, bone marrow, CSF, circulating CD4+ T cell subsets, and plasma. No HIV was detected from tissues obtained from PrEP Participant B, but low-level HIV RNA or DNA was intermittently detected from various CD4+ T cell subsets. Over 500 million CD4+ T cells were assayed from both participants in a humanized mouse outgrowth assay. Three of 8 mice infused with CD4+ T cells from PrEP Participant B developed viremia (50 million input cells/surviving mouse), but only 1 of 10 mice infused with CD4+ T cells from PrEP Participant A (53 million input cells

    The effect of two different estrogen/gestagen regimens and 24R,25-(OH)2-cholecalciferol on bone formation was studied in a randomized trial with 144 healthy postmenopausal women. Urinary excretion (UE) of /sup 99m/technetium-diphosphonate and serum alkaline phosphatase (AP) was determined before and then once a year for 2 years of treatment. Both estimates of bone formation showed highly significant decreases (p less than .001) to normal premenopausal levels in women receiving unopposed 17 beta-estradiol or in a sequential combination with progestagen, whereas unchanged high values were found in the groups receiving 24R,25-(OH)2D3 and placebo. The data show that bone turnover increases in early postmenopausal women concomitantly with the loss of bone mass, and that hormonal substitutional therapy normalizes the total skeletal turnover as well as preventing bone loss.

    What is known on the subject? Despite the increase of studies into the predictors of psychological distress, few have attempted to address the mediation of stress in the relationship between early trauma and psychological distress. What does this paper add to existing knowledge? In this study, college students with trauma exposure before the age of 18 years reported high levels of college life stress and psychological distress. In addition, of the subcategories of early trauma, emotional abuse was most highly correlated with current stress and psychological distress. This paper confirmed the partial mediating effect of stress between early trauma and psychological distress among Korean college students. In other words, this study found a direct effect of early trauma on current psychological distress and an indirect effect of early trauma on psychological distress mediated through life stress. What are the implications for practice? Early trauma and stress should be considered when developing interventions for college students' mental health, although individuals with trauma exposure have difficulties disclosing their traumatic event. Therefore, we suggest that stress management may be easier to apply and more effective in promoting college students' mental health than trauma-focused interventions. Research has shown that early trauma and stress may affect current psychological distress. However, few studies have attempted to address the mediation of stress between early trauma and psychological distress. This cross-sectional observational study aimed to examine the mediating effects of stress on the association between early trauma and psychological distress in Korean college students. Participants included 216 college students (51.4% male) who completed self-report questionnaires assessing early trauma, college life stress, and psychological distress. Early trauma, stress, and psychological distress were significantly correlated. Of the subcategories of early

    defined as tissue selective estrogen complex (TSEC). The bazedoxifene with conjugated estrogen is able to reduce climacteric symptoms, reducing bone turnover and preserving BMD. Studies investigating the actions of phytoestrogens on BMD or bone turnover are largely contradictory, making them inconclusive. At the present time, phytoestrogens cannot be recommended for postmenopausal osteoporosis. In conclusion, the use of HRT for osteoporosis prevention is based on biology, epidemiology, animal and preclinical data, observational studies and randomized, clinical trials. Osteoporosis prevention can actually be considered as a major additional effect in climacteric women who use HRT for treatment of climacteric symptoms. Bone protection is one of the major benefits of HRT. The possibility that low dose HRT or TSEC causes a decrease in fracture risk is not demonstrated but the scientific evidence is compelling. Conversely, established osteoporosis, often occurring in elderly women, can better be treated with specific treatments, such as bisphosphonates or, in more severe and selected cases, anabolic agents (teriparatide).

    Less advantaged social classes usually have unhealthier lifestyles and have more difficult access to health resources. In this work we study the possible association between poverty and the prevalence of obesity and oophorectomy in a population of postmenopausal women. Cross-sectional observational study. To study in a population of postmenopausal women in poverty the possible differences in the prevalence of obesity and oophorectomy, and to compare some other gynaecological data: age at menarche, age at menopause, fertile years, number of pregnancies, breastfeeding and the use of hormonal replacement therapy (HRT). All patients were interviewed personally. A questionnaire was used to find out about their lifestyles and the medication they were taking. Their medical records were reviewed to confirm the existence of some diseases. A complete physical examination was performed with every patient. Weight and height were measured with the patient dressed in light clothes. Blood was obtained in a fasting state in order to carry out some analyses. Poverty was defined according to the Spanish National Institute of Statistics criteria. We enrolled 1225 postmenopausal women; 449 (36.6%) were under the threshold of poverty, defined by the Spanish National Institute of Statistics. Postmenopausal women in poverty had higher body mass index (29.2 +/- 4.8 versus 27.0 +/- 4.7 kg/m(2) P poverty (44.2% versus 24.3%, P = 0.001). The prevalence of oophorectomy was also higher in women in poverty (32.7% versus 27.2%, P poverty had had a greater number of pregnancies (3 versus 2, P = 0.001). They also showed a higher rate of breastfeeding than women in medium and high social classes (65% versus 59%, P = 0.037). There were no statistically significant differences between the groups in either the age of menopause or fertile years, nor in the use of HRT. Postmenopausal women in poverty have higher levels of obesity, and also a greater prevalence of oophorectomy than women of medium and

    Although the coexistence of osteoarthritis and osteoporosis is considered as uncommon, it has been suggested that, in postmenopausal women, disc space narrowing increases the risk of vertebral fracture. The aim of this study was to check this hypothesis in postmenopausal women with osteoporosis. We analysed the relationship between vertebral fractures and spine osteoarthritis in 410 postmenopausal women with osteoporosis: in this population both disc space narrowing and osteophytes are inversely related to vertebral fractures. This study is based on baseline data collected in a multicentre, prospective and 6-month longitudinal observational study. 410 postmenopausal women (74+/-5 years) were enrolled who had consulted for back pain, and had osteoporosis (according to WHO definition). Spine x-rays were performed according to standardised procedures. Vertebral fractures were evaluated from T4 to L4 using the Genant's semiquantitative method; osteoarthritis was evaluated by scoring osteophytes and disc space narrowing at all levels of the thoracic and lumbar spine, and by a qualitative assessment of facet joint arthritis. The prevalence of vertebral fractures was 52.4%. At least one osteophyte, one disc space narrowing and one facet arthritis were present in 90.2, 64.6 and 77.8% of patients respectively. There was an inverse association between vertebral fractures and osteoarthritis: odds ratios adjusted for age and weight (95% CI) were 0.38 (0.17-0.86), p = 0.02 and 0.27 (0.16-0.46), p<10(-4) for the presence of at least one osteophyte, and of at least three disc space narrowings respectively. In a cluster analysis, it was possible to identify a subgroup of patients without any disc space narrowing, and another subgroup with all patients having at least one disc space narrowing; the proportion of patients having more than three vertebral fractures was 25.2 and 15.9% in these two clusters respectively. Disc space narrowing and osteophytes are associated with a

    Vegan diet has been associated with lower risk of cardiovascular diseases and mortality, partly due to its effects on serum lipid profiles. Lipid profiles [high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and triglycerides (TG)] have not been fully elucidated either in pre and postmenopausal vegans or in ovo-lacto vegetarians. This study aimed to compare lipid profiles among vegans, ovo-lacto vegetarians and omnivores. Demographic data and lipid profiles were obtained from the 2002 Taiwanese Survey on Hypertension, Hyperglycemia and Hyperlipidemia. Multivariate linear regression analysis was used to examine factors significantly and independently associated with different categories of veganism and to estimate the β value of lipid profiles in the dietary types. A total of 2397 premenopausal and 1154 postmenopausal participants who did not receive lipid lowering drugs were enrolled. Premenopausal vegans had significantly lower HDL-C and higher TG, LDL-C/HDL-C, total cholesterol (TC)/HDL-C and TG/HDL-C compared with omnivores. For postmenopausal women, vegans had lower TC while ovo-lacto vegetarians were observed with low HDL-C when compared with omnivores. Multivariate linear regression analyses showed that vegan and ovo-lacto vegetarian diets decreased HDL-C levels in premenopausal women (β = -7.63, p = 0.001 and β = -4.87, p = 0.001, respectively). There were significant associations between lower LDL-C and ovo-lacto vegetarian diets (β = -7.14, p = 0.008) and also between TG and vegan diet (β = 23.37, p = 0.008), compared with omnivorous diet. Post-menopausal women reported to have consumed either a vegan or an ovo-lacto vegetarian diet were at the risk of having low HDL-C unlike those that consumed omnivorous diets (β = -4.88, p = 0.015 and β = -4.48, p = 0.047). There were no significant changes in LDL-C in both pre and postmenopausal vegans. Vegan diet was

    On South African public hospital wards, observation charts do not incorporate early warning scoring (EWS) systems to inform nurses when to summon assistance. The aim of this trial was to test the impact of a new chart incorporating a modified EWS (MEWS) system and a linked training program on nurses' responses to clinical deterioration (primary outcome). Secondary outcomes were: numbers of patients with vital signs recordings in the first eight postoperative hours; number of times each vital sign was recorded; and nurses' knowledge. A pragmatic, parallel-group, cluster randomized, controlled clinical trial of intervention versus standard care was conducted in three intervention and three control adult surgical wards in an 867-bed public hospital in Cape Town, between March and July 2010; thereafter the MEWS chart was withdrawn. A total of 50 out of 122 nurses in full-time employment participated. From 1,427 case notes, 114 were selected by randomization for assessment. The MEWS chart was implemented in intervention wards. Control wards delivered standard care, without training. Case notes were reviewed two weeks after the trial's completion. Knowledge was assessed in both trial arms by blinded independent marking of written tests before and after training of nurses in intervention wards. Analyses were undertaken with IBM SPSS software on an intention-to-treat basis. Patients in trial arms were similar. Introduction of the MEWS was not associated with statistically significant changes in responses to clinical deterioration (50 of 57 received no assistance versus 55 of 57, odds ratio (OR): 0.26, 95% confidence interval (CI): 0.05 to 1.31), despite improvement in nurses' knowledge in intervention wards. More patients in intervention than control wards had recordings of respiratory rate (27 of 57 versus 2 of 57, OR: 24.75, 95% CI: 5.5 to 111.3) and recordings of all seven parameters (5 of 57 versus 0 of 57 patients, risk estimate: 1.10, 95% CI: 1.01 to 1.2).

    Cardiopulmonary resuscitation (CPR) is a series of lifesaving actions that improve the chance of survival following cardiac arrest (CA). Many clinical and laboratory parameters, such as the presence of asystole, out-of-hospital CPR, and duration of cardiac arrest, are associated with failed CPR in patients with CA. Asystole is a state of no cardiac electrical activity, along with the absence of contractions of the myocardium and absence of cardiac output. Oxidative stress index (OSI), which is the ratio of total oxidative status to total antioxidant status, increases by ischemia-reperfusion injury. We investigated whether OSI levels in patients with CA could predict early mortality after CPR. This study has a prospective observational cohort design. Five patients with a history of cancer, four patients who developed hemolysis in their blood, six patients who were transferred to our hospital from other hospitals, and six patients in whom blood samples for OSI could not be stored properly were excluded. Finally, a total of 90 in-hospital or out-of-hospital CA patients and 40 age- and sex-matched healthy volunteers as the control group were evaluated prospectively. The patients were classified according to the CPR response into a successful group (n=46) and a failed group (n=44). Comparisons between groups were performed using one-way ANOVA with post hoc analysis by Tukey's HSD or independent samples t-test and the Kruskal-Wallis tests or Mann- Whitney U test for normally and abnormally distributed data, respectively. Also, we used chi-square test, Spearman's correlation test, univariate and multible logistic regression analyses, and receiver operator characteristic curve analysis. OSI was 3.0±4.0, 5.6±4.3, and 8.7±3.8 in the control group, the successful CPR group, and the failed CPR group, respectively (pOSI on admission, ischemia-modified albumin, presence of asystole, mean duration of cardiac arrest, out-of-hospital CPR, pH, and potassium and sodium levels were

    This thesis is based on studies conducted in the period 2010-2014 at Department of Public Health, University of Copenhagen and at Department of Epidemiology and Population Health, Albert Einstein College of Medicine, New York. The results are presented in three scientific papers and a synopsis. The main objective of the thesis was to determine mechanisms underlying social inequality (defined by educational level) in postmenopausal breast cancer (BC) by addressing mediating effects through hormone therapy (HT) use, BMI, lifestyle and reproductive factors. The results of previous studies suggest that the higher risk of postmenopausal BC among women of high socioeconomic position (SEP) may be explained by reproductive factors and health behaviors. Women of higher SEP generally have fewer children and give birth at older ages than women of low SEP, and these factors have been found to affect the risk of BC - probably through altered hormone levels. Adverse effects on BC risk have also been documented for modifiable health behaviors that may affect hormone levels, such as alcohol consumption, high BMI, physical inactivity, and HT use. Alcohol consumption and HT use are likewise more common among women of higher SEP. The analyses were based on the Social Inequality in Cancer (SIC) cohort and a subsample of the Women's Health Initiative Observational Study (WHI-OS). The SIC cohort was derived by pooling 6 individual studies from the Copenhagen area including 33,562 women (1,733 BC cases) aged 50-70 years at baseline. The subsample of WHI-OS consisted of two case-cohort studies with measurements of endogenous estradiol (N = 1,601) and insulin (N = 791). Assessment of mediation often relies on comparing multiplicative models with and without the potential mediator. Such approaches provide potentially biased results, because they do not account for mediator-outcome confounding, exposure-dependent mediator-outcome confounding, exposure-mediator interaction and interactions

    Aging causes micro- and macrovascular endothelial dysfunction, as assessed by endothelium-dependent dilation (EDD), which can be prevented and reversed by habitual aerobic exercise (AE) in men. However, in estrogen-deficient postmenopausal women, whole forearm microvascular EDD has not been studied, and a beneficial effect of AE on macrovascular EDD has not been consistently shown. We assessed forearm blood flow in response to brachial artery infusions of acetylcholine (FBF ACh ), a measure of whole forearm microvascular EDD, and brachial artery flow-mediated dilation (FMD), a measure of macrovascular EDD, in 12 premenopausal sedentary women (Pre-S; 24 ± 1 yr; V̇o 2max = 37.5 ± 1.6 ml·kg -1 ·min -1 ), 25 estrogen-deficient postmenopausal sedentary women (Post-S; 62 ± 1 yr; V̇o 2max = 24.7 ± 0.9 ml·kg -1 ·min -1 ), and 16 estrogen-deficient postmenopausal AE-trained women (Post-AE; 59 ± 1 yr; V̇o 2max = 40.4 ± 1.4 ml·kg -1 ·min -1 ). FBF ACh was lower in Post-S and Post-AE compared with Pre-S women (135 ± 9 and 116 ± 17 vs. 193 ± 21 AUC, respectively, both P healthy nonobese estrogen-deficient postmenopausal women, despite being associated with lower systemic markers of inflammation and oxidative stress. This is the first study to demonstrate that habitual aerobic exercise may not protect against age/menopause-related whole forearm microvascular endothelial dysfunction in healthy nonobese estrogen-deficient postmenopausal women, consistent with recent findings regarding macrovascular endothelial function. This is in contrast to what is observed in healthy middle-aged and older aerobic exercise-trained men. Copyright © 2017 the American Physiological Society.

  15. Hormone replacement therapy and the prevention of postmenopausal osteoporosis

    2014-01-01

    Fracture prevention is one of the public health priorities worldwide. Estrogen deficiency is the major factor in the pathogenesis of postmenopausal osteoporosis, the most common metabolic bone disease. Different effective treatments for osteoporosis are available. Hormone replacement therapy (HRT) at different doses rapidly normalizes turnover, preserves bone mineral density (BMD) at all skeletal sites, leading to a significant, reduction in vertebral and non-vertebral fractures. Tibolone, a selective tissue estrogenic activity regulator (STEAR), is effective in the treatment of vasomotor symptoms, vaginal atrophy and prevention/treatment of osteoporosis with a clinical efficacy similar to that of conventional HRT. Selective estrogen receptor modulators (SERMs) such as raloxifene and bazedoxifene reduce turnover and maintain or increase vertebral and femoral BMD and reduce the risk of osteoporotic fractures. The combination of bazedoxifene and conjugated estrogens, defined as tissue selective estrogen complex (TSEC), is able to reduce climacteric symptoms, reduce bone turnover and preserve BMD. In conclusion, osteoporosis prevention can actually be considered as a major additional benefit in climacteric women who use HRT for treatment of climacteric symptoms. The use of a standard dose of HRT for osteoporosis prevention is based on biology, epidemiology, animal and preclinical data, observational studies and randomized, clinical trials. The antifracture effect of a lower dose HRT or TSEC is supported by the data on BMD and turnover, with compelling scientific evidence. PMID:26327857

    Genetic and environmental factors are responsible for variations in the frequency of osteoporosis. Prevalence of osteoporosis in Mapuche women (native Chileans) is unknown. To assess the prevalence and risk factors for osteoporosis in Mapuche women. A random sample of 95 asymptomatic postmenopausal Mapuche females, stratified by age, was studied. Women with diseases or medications that could interfere with calcium metabolism were excluded. Spine and femoral neck bone mass density was determined using a Lunar DPX Alpha densitometer. Seventeen percent of women had normal bone mineral density in both spine and femoral neck. In the spine, 25.3% had a normal bone mineral density, 17.9% had osteopenia and 56.8% had osteoporosis. In the femoral neck, 34.7% had a normal bone mineral density, 57.9% had osteopenia, and 7.4% had osteoporosis. There was a positive correlation between bone mineral density and body mass index. Women with more than one hour per day of physical activity, had a significantly lower proportion of osteopenia or osteoporosis. No association between bone mineral density and parity or calcium intake, was observed. There is a high prevalence of osteopenia and osteoporosis among Mapuche women. Osteoporosis was associated with low body mass index.

    The Docetaxel Epirubicin Adjuvant (DEVA) trial evaluated the efficacy and toxicity of incorporating docetaxel after epirubicin to create a sequential anthracycline-taxane regimen in early breast cancer. After complete tumor excision, postmenopausal women with node-positive early breast cancer were randomly assigned to either epirubicin 50 mg/m(2) on days 1 and 8 every 4 weeks for six cycles (EPI × 6) or three cycles of epirubicin 50 mg/m(2) on days 1 and 8 every 4 weeks followed by three cycles of docetaxel 100 mg/m(2) on day 1 every 3 weeks (EPI-DOC). A subset of patients also participated in a quality of life (QOL) study. The primary end point was disease-free survival (DFS). From 1997 to 2005, 803 patients entered DEVA (EPI × 6, n = 397; EPI-DOC, n = 406). At a median follow-up of 64.7 months (interquartile range, 45.2 to 84.4 months), 198 DFS events had been reported (EPI × 6, n = 114; EPI-DOC, n = 84). The 5-year DFS rates were 72.7% (95% CI, 68.0% to 77.3%) for epirubicin alone and 79.5% (95% CI, 75.2% to 83.8%) for epirubicin followed by docetaxel; evidence of improvement in DFS was observed with EPI-DOC (hazard ratio [HR], 0.68; 95% CI, 0.52 to 0.91; P = .008). One hundred twenty-seven patients have died (EPI × 6, n = 75; EPI-DOC, n = 52); a reduction in deaths was observed with EPI-DOC (HR, 0.66; 95% CI, 0.46 to 0.94; P = .02). The 5-year overall survival rates were 81.8% (95% CI, 77.7% to 85.9%) for epirubicin and 88.9% (95% CI, 85.5% to 92.2%) for epirubicin followed by docetaxel. Assessment of toxicity and QOL showed that EPI-DOC was associated with greater toxicity but with no difference in QOL between arms during follow-up. These results suggest, within a relatively small trial, that substitution of docetaxel for epirubicin for the last three cycles of chemotherapy results in improved outcome in postmenopausal women with node-positive, early breast cancer compared with six cycles of epirubicin monotherapy.

    To characterize a new lethal fetal and early postnatal variant of adenylosuccinate lyase (ADSL) deficiency. This was a retrospective analysis of 6 patients with very early presentation of ADSL deficiency. Most of the 6 patients had impaired intrauterine growth, microcephaly, fetal hypokinesia, and a lack of fetal heart rate variability. Postnatally, they shared severe muscular hypotonia necessitating mechanical ventilation, intractable seizures, and early death. All 6 patients had biochemical evidence of severe (type 1) disease and low residual ADSL activities. All were compound heterozygous for mutations that, based on expression studies, have a pronounced effect on ADSL activity and/or stability. ADSL deficiency may present with prenatal growth restriction, fetal and neonatal hypokinesia, and rapidly fatal neonatal encephalopathy. This clinical presentation is associated with genotypes resulting in very low residual enzyme activity.

    2003-01-01

    A pilot study to estimate the prevalence of osteopenia and osteoporosis in postmenopausal Saudi woman. Lumbarspine bone density was measured in 830 postmenopausal Saudi women 50-80 years of age (average 59 years), using dual x-ray absorptiometry (DXA) at the King Khalid University Hospital,Riyadh,Kingdom of Saudi Arabia between 1989 and 1999. The result of the bone mineral density (BMD) in gram/cm2 were compared to the peak bone density (PBD) in healthy young women (T-score). Based on the definition of World Health Organization (WHO),the T-score value was considerd for analysis. Accordingly 248 (29.9%) subjects showed normal results,mean MBD of 1.117+-0.13 and T-score of-0.66SD; whlie 254(30.6%) subjects showed osteopenia ,mean BMD of 0.983+-0.11and T-score of -2.4 SD and 328( 39.5%) subjects showed osteoporosis,mean BMD of 0.767+-0.11and T-score of -3.4SD. when 830 subjects were analyzed by decades ,there were 42.3% normal , 33.4% osteopenia and 24.3% osteoporosis in age 50-59 years; 11% normal, 27% with osteopenia and 62% with osteoporosis in age 60-69 years while in older age 70-79 years only 4.6 had normal BMD, 21.5% had osteopenia and73.8% had osteoporosis. Osteopenia and osteoporosis are common among postmenopausal Saudi women and should be considerd as a matter of public health .Bone densitometry should be used to acess the severity of bone loss, identify those who need therapy and for follow up and early diagnosis of those with osteopenia in order to institute proper therapy and avoid future osteoporosis.

    We determined whether the association between breast density and breast cancer risk and cancer severity differs according to menopausal status and postmenopausal hormone therapy (HT) use. We collected data on 587,369 women who underwent 1,349,027 screening mammography examinations; 14,090 women were diagnosed with breast cancer. We calculated 5-year breast cancer risk from a survival model for subgroups of women classified by their Breast Imaging Reporting and Data System (BIRADS) breast density, age, menopausal status, and current HT use, assuming a body mass index of 25 kg/m(2). Odds of advanced (ie, IIb, III, IV) versus early (ie, I, IIa) stage invasive cancer was calculated according to BIRADS density. Breast cancer risk was low among women with low density (BIRADS-1): women age 55 to 59 years, 5-year risk was 0.8% (95% CI, 0.6 to 0.9%) for non-HT users and 0.9% (95% CI, 0.7% to 1.1%) for estrogen and estrogen plus progestin users. Breast cancer risk was high among women with very high density (BIRADS-4), particularly estrogen plus progestin users: women age 55 to 59 years, 5-year risk was 2.4% (95% CI, 2.0% to 2.8%) for non-HT users, 3.0% (95% CI, 2.6% to 3.5%) for estrogen users, and 4.2% (95% CI, 3.7% to 4.6%) for estrogen plus progestin users. Advanced-stage breast cancer risk was increased 1.7-fold for postmenopausal HT users who had very high density (BIRADS-4) compared to those with average density (BIRADS-2). Postmenopausal women with high breast density are at increased risk of breast cancer and should be aware of the added risk of taking HT, especially estrogen plus progestin.

    Early diagnosis of the onset of osteoporosis is key to the delivery of effective therapy. Biochemical markers of bone turnover provide a means of evaluating skeletal dynamics that complements static measurements of BMD by DXA. Conventional clinical measurements of bone turnover, primarily the estimation of collagen and its breakdown products in the blood or urine, lack both sensitivity and specificity as a reliable diagnostic tool. As a result, improved tests are needed to augment the use of BMD measurements as the principle diagnostic modality. In this study, the serum proteome of 58 postmenopausal women with high or low/normal bone turnover (training set) was analyzed by surface enhanced laser-desorption/ionization time-of-flight mass spectrometry, and a diagnostic fingerprint was identified using a variety of statistical and machine learning tools. The diagnostic fingerprint was validated in a separate distinct test set, consisting of serum samples from an additional 59 postmenopausal women obtained from the same Mayo cohort, with a gap of 2 yr. Specific protein peaks that discriminate between postmenopausal patients with high or low/normal bone turnover were identified and validated. Multiple supervised learning approaches were able to classify the level of bone turnover in the training set with 80% sensitivity and 100% specificity. In addition, the individual protein peaks were also significantly correlated with BMD measurements in these patients. Four of the major discriminatory peaks in the diagnostic profile were identified as fragments of interalpha-trypsin-inhibitor heavy chain H4 precursor (ITIH4), a plasma kallikrein-sensitive glycoprotein that is a component of the host response system. These data suggest that these serum protein fragments are the serum-borne reflection of the increased osteoclast activity, leading to the increased bone turnover that is associated with decreasing BMD and presumably an increased risk of fracture. In conjunction with the

    Cardio- and cerebro-vascular diseases are two leading causes of death and long-term disability in postmenopausal women. The acute fall of estrogen in menopause is associated with increased cardiovascular risk. The relative contribution of androgen to this risk is also being recognized. The use of more sensitive assays for estradiol measurement and the study of receptor and carrier protein gene polymorphisms have provided some new information on the clinical relevance of endogenous sex steroids. We provide an update on the role of endogenous sex steroids on cardio- and cerebro-vascular disease in the postmenopausal period. We performed a PubMed search using the terms 'endogenous estrogen', 'androgen', 'cardiovascular disease', 'cerebro-vascular disease', 'stroke', 'carotid artery disease', and 'subclinical atherosclerosis'. The majority of studies show a beneficial effect of endogenous estrogen on the vasculature; however, there are a few studies reporting the contrary. A significant body of literature has reported associations of endogenous estrogen and androgen with early markers of atherosclerosis and metabolic parameters. Data on the relevance of endogenous sex steroids in heart disease and stroke are inconclusive. Most studies support a beneficial role of endogenous estrogens and, probably, an adverse effect of androgens in the vasculature in postmenopausal women. However, the described associations may not always be considered as causal. It is possible that circulating estrogen might represent a marker of general health status or alternatively reflect the sum of endogenous androgens aromatized in the periphery. Elucidating the role of sex steroids in cardio- and cerebro-vascular disease remains an interesting field of future research.

Both menopause and aging are related factors leading to greater risk of bone disease, particularly among postmenopausal women. Hence, the main purpose of this study was to investigate the differences in biochemical markers of bone turnover and to evaluate the association of hormones and age-related factors with biochemical markers between pre- and postmenopausal women.Methods: A descriptive cross-sectional study was conducted over a period of 6 months among the female population of Dholahity community, Lalitpur, Nepal. A total of 496 healthy women were selected based on the questionnaire strategy. Among them, 244 were premenopausal and 252 were postmenopausal women. Different bone markers were evaluated as per the guideline provided by the reagent manufacturer, and hormonal assay, particularly estradiol level assessment, was performed by chemiluminescence immunoassay-based technique.Results: A significant decrease in serum calcium level and estradiol level was observed in postmenopausal women as compared to premenopausal women, whereas a significant increase in serum phosphorus and alkaline phosphatase (ALP levels was seen among postmenopausal (p<0.001. Age was significantly correlated with bone markers (ALP and calcium in postmenopausal group (p<0.005, while there was no significant correlation in premenopausal group. In addition, there was significant positive correlation between calcium and estradiol in postmenopausal women, while ALP was negatively correlated with estradiol in that group.

    School absenteeism is a common data source in syndromic surveillance, which allows for the detection of outbreaks at an early stage. Previous studies focused on its correlation with other data sources. In this study, we evaluated the effectiveness of control measures based on early warning signals from school absenteeism surveillance in rural Chinese schools. A school absenteeism surveillance system was established in all 17 primary schools in 3 adjacent towns in the Chinese region of Hubei. Three outbreaks (varicella, mumps, and influenza-like illness) were detected and controlled successfully from April 1, 2012, to January 15, 2014. An impulse susceptible-exposed-infectious-recovered model was used to fit the epidemics of these three outbreaks. Moreover, it simulated the potential epidemics under interventions resulting from traditional surveillance signals. The effectiveness of the absenteeism-based control measures was evaluated by comparing the simulated datasets. The school absenteeism system generated 52 signals. Three outbreaks were verified through epidemiological investigation. Compared to traditional surveillance, the school absenteeism system generated simultaneous signals for the varicella outbreak, but 3 days in advance for the mumps outbreak and 2-4 days in advance for the influenza-like illness outbreak. The estimated excess protection rates of control measures based on early signals were 0.0%, 19.0-44.1%, and 29.0-37.0% for the three outbreaks, respectively. Although not all outbreak control measures can benefit from early signals through school absenteeism surveillance, the effectiveness of early signal-based interventions is obvious. School absenteeism surveillance plays an important role in reducing outbreak spread.

    Full Text Available The purpose of this study was to examine an influence of a mixed aerobic and strength training program (MAST on anthropometry, serum lipid levels, physical performance, and functional fitness in obese postmenopausal women. The MAST sessions were held three times per week, and the exercise program lasted for 10 weeks. The exercise group demonstrated a statistically significant improvement in maximal oxygen uptake, a waist/hip ratio, and strength of the upper and lower body. An increase in LDL-C levels was observed in the control group. A 10-week MAST program encompassing Nordic-walking as an aerobic component, and strength exercises, induces positive changes in functional fitness, HDL-C, LDL-C and a waist/hip ratio in obese postmenopausal women. The observed changes implicate an increase in a health-related quality of life among the women administered to the physical exercise program

  12. Denosumab in Postmenopausal Osteoporosis: What the Clinician Needs to Know

    Lewiecki, E. Michael

    2009-01-01

    Denosumab is a subcutaneously (SC) administered investigational fully human monoclonal antibody to receptor activator of nuclear factor-kB ligand (RANKL), a cytokine member of the tumor necrosis factor family that is the principal mediator of osteoclastic bone resorption. RANKL stimulates the formation, activity, and survival of osteoclasts, and is implicated in the pathogenesis of postmenopausal osteoporosis and other skeletal disorders associated with increased bone remodeling. Denosumab binds RANKL, preventing it from binding to RANK, thereby reducing the formation, activity, and survival of osteoclasts and slowing the rate of bone resorption. Postmenopausal women with low bone mineral density (BMD) treated with denosumab have a reduction of bone turnover markers and an increase in BMD that is rapid, sustained, and reversible. In postmenopausal women with osteoporosis, denosumab reduces the risk of vertebral, hip, and nonvertebral fractures. In postmenopausal women with low BMD randomized to receive denosumab or alendronate, denosumab is associated with a significantly greater increase in BMD and further reduction in bone turnover markers compared with alendronate. In postmenopausal women with low BMD who were previously treated with alendronate, those who switched to denosumab have a significantly greater BMD increase and further reduction in bone turnover markers compared with those continuing alendronate. Denosumab is well tolerated with a favorable safety profile. It is a promising emerging drug for the prevention and treatment of osteoporosis, offering a long dosing interval of every 6 months and convenient SC dosing, with the potential of improving long-term adherence to therapy compared with current oral treatments.

    Menopause may be a risk factor for hearing loss, and postmenopausal hormone therapy (HT) has been proposed to slow hearing decline; however, there are no large prospective studies. We prospectively examined the independent relations between menopause and postmenopausal HT and risk of self-reported hearing loss. Prospective cohort study among 80,972 women in the Nurses' Health Study II, baseline age 27 to 44 years, followed from 1991 to 2013. Baseline and updated information was obtained from detailed validated biennial questionnaires. Cox proportional-hazards regression models were used to examine independent associations between menopausal status and postmenopausal HT and risk of hearing loss. After 1,410,928 person-years of follow-up, 18,558 cases of hearing loss were reported. There was no significant overall association between menopausal status, natural or surgical, and risk of hearing loss. Older age at natural menopause was associated with higher risk. The multivariable-adjusted relative risk of hearing loss among women who underwent natural menopause at age 50+ years compared with those aged less than 50 years was 1.10 (95% confidence interval [CI] 1.03, 1.17). Among postmenopausal women, oral HT (estrogen therapy or estrogen plus progestogen therapy) was associated with higher risk of hearing loss, and longer duration of use was associated with higher risk (P trend menopause and longer duration of postmenopausal HT are associated with higher risk of hearing loss.

    Postmenopausal osteoporosis, a silent epidemic, has become a major health hazard, afflicting about 50% of postmenopausal women worldwide and is thought to be a disease with one of the highest incidences in senile people. It is a chronic, progressive condition associated with micro-architectural deterioration of bone tissue that results in low bone mass, decreased bone strength that predisposes to an increased risk of fracture. Women are more likely to develop osteoporosis than men due to reduction in estrogen during menopause which leads to decline in bone formation and increase in bone resorption activity. Estrogen is able to suppress the production of proinflammatory cytokines like interleukin (IL)-1, IL-6, IL-7 and tumor necrosis factor (TNF-α). This is why these cytokines are elevated in postmenopausal women. In this review article we have made an attempt to collate the various methods and parameters most frequently used for screening of antiosteoporotic activity in postmenopausal osteoporosis. Pertaining to ovariectomized animal model, this is the most appropriate model for studying the efficacy of different drugs to prevent bone loss in postmenopausal osteoporosis.

    Postmenopausal women have shown proactive willingness to take responsibility for their changing health care needs. The example of osteoporosis is a model that when educated of their bone health status, this cohort follows through with prevention and treatment regimens. Postmenopausal status is considered to be a risk factor for periodontitis. It is known that up to 50% of periodontal disease goes undiagnosed. The goal of periodontal therapy is to prevent tooth loss. Is there a need, then to educate and inform postmenopausal women of their periodontal status? Can dentists provide a greater service to this cohort by increasing education and information? The current study compares patient perception to actual clinical findings in 94 postmenopausal women. Patients are informed of their diagnosis, and educated about the disease, its risk factors and preventive and treatment modalities. Detailed interviews examine the patient intentions to follow up on preventive and treatment regimens suggested. Although 97.8% of participants reported having "healthy gums", 36.2% had severe periodontitis in at least one site. Interviews reveal that patients associated disease with abscess, and would be likely to follow prevetive and treatment regimens when they were informed of their diagnosis and educated on the topic. The findings suggest a need to make education a priority when treatment postmenopausal women.

    Full Text Available E Michael LewieckiNew Mexico Clinical Research & Osteoporosis Center, Albuquerque, NM, USAAbstract: Lasofoxifene is a selective estrogen receptor modulator (estrogen agonist/antagonist that has completed phase III trials to evaluate safety and efficacy for the prevention and treatment of osteoporosis and for the treatment of vaginal atrophy in postmenopausal women. In postmenopausal women with low or normal bone mineral density (BMD, lasofoxifene increased BMD at the lumbar spine and hip and reduced bone turnover markers compared with placebo. In women with postmenopausal osteoporosis, lasofoxifene increased BMD, reduced bone turnover markers, reduced the risk of vertebral and nonvertebral fractures, and decreased the risk of estrogen receptor-positive breast cancer. In postmenopausal women with low bone mass, lasofoxifene improved the signs and symptoms of vulvovaginal atrophy. Clinical trials show that lasofoxifene is generally well tolerated with mild to moderate adverse events that commonly resolve even with drug continuation. Lasofoxifene has been associated with an increase in the incidence of venous thromboembolic events, hot flushes, muscle spasm, and vaginal bleeding. It is approved for the treatment of postmenopausal women at increased risk for fracture in some countries and is in the regulatory review process in others.Keywords: osteoporosis, SERM, fracture, efficacy, safety, BMD, CP-336,156

    Full Text Available To investigate the correlation between postmenopausal osteoporosis (PMO and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-6, the receptor activator of nuclear factor-κB ligand (RANKL, and osteoprotegerin (OPG and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    The aging process is accompanied by several changes, such as a decrease in physical fitness. To establish the relationship between a sedentary behavior (sit ≥4 hours/day) and physical fitness in 457 women aged 65 years or older. Physical fitness was evaluated by 8 adapted tests from "Senior Fitness Test" and "Eurofit Testing Battery". ANOVA was used to analyze differences between groups according to the hours of sitting and logistic regression analysis was used to study the association of the sedentary behavior with low fitness, using as reference the 20th percentile of the normative values in Spain (EXERNET Project). Sedentary women had lower balance, legs and arms strength, arms flexibility, walking speed and endurance (p < 0.05). In addition, those women who sat ≥4 hours/day had higher odds for having low fitness in most of the mentioned tests, regardless of the hours of walking (p < 0.05). Sitting for a long time has a negative influence on physical fitness among postmenopausal women independently of walking time. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

    2016-07-01

    Full Text Available A seventy-three-year-old patient%u2019s vaginal examination revealed a semi-mobile cystic structure visualised at the middle third portion of the posterior vaginal wall. The cyst was excised and the cyst wall was sent for pathological examination. The histopathological examination of the cyst with CD10 staining and tests for nuclear estrogen receptor positivity and nuclear progesteron receptor positivity revealed that the cyst wall contained endometrial stromal cells, endometrial surface epithelial cells, and hemosiderin-laden macrophages. Endometriosis externa was diagnosed based on the above findings. The case we report here, of an isolated vaginal endometriotic cyst, is unique because of its presentation in a postmenopausal woman without any history of infertility, any gynecologic surgery, or hormone replacement therapy. The reasonable explanation for this case might include certain mechanisms such as the self-sustaining existence of endometriotic cells that were implanted during the premenopausal period to the vagina and that maintain local estrogen production. No single hypothesis can explain the pathophysiology of endometriosis, given all of its various forms and presentations.

    Laboratory research suggests that components in coffee and tea may have anticarcinogenic effects. Some epidemiologic studies have reported that women who consume coffee and tea have a lower risk for melanoma. We assessed coffee, tea, and melanoma risk prospectively in the Women's Health Initiative - Observational Study cohort of 66,484 postmenopausal women, followed for an average of 7.7 years. Coffee and tea intakes were measured through self-administered questionnaires at baseline and at year 3 of follow-up. Self-reported incident melanomas were adjudicated using medical records. Cox proportional hazard models were used to estimate risk, adjusting for covariates, with person-time accumulation until melanoma diagnosis (n=398), death, loss to follow-up, or through 2005. Daily coffee [hazard ratio (HR)=0.87, 95% confidence interval (CI) 0.68-1.12] and tea (HR=1.03, 95% CI 0.81-1.31) intakes were not significantly associated with melanoma risk compared with nondaily intake of each beverage. No significant trends were observed between melanoma risk and increasing intakes of coffee (P for trend=0.38) or tea (P for trend=0.22). Women who reported daily coffee intake at both baseline and year 3 had a significantly decreased risk compared with women who reported nondaily intake at both time points (HR=0.68, 95% CI 0.48-0.97). Consistent daily tea intake was not associated with decreased melanoma risk. Overall, there is no strong evidence that increasing coffee or tea consumption can lead to a lower melanoma risk. We observed a decrease in melanoma risk among long-term coffee drinkers, but the lack of consistency in the results by dose and type cautioned against overinterpretation of the results.

    Early observations of Type Ia supernovae (SNe Ia) provide a unique probe of their progenitor systems and explosion physics. Here we report the intermediate Palomar Transient Factory (iPTF) discovery of an extraordinarily young SN Ia, iPTF 16abc. By fitting a power law to our early light curve, we infer that first light for the SN, that is, when the SN could have first been detected by our survey, occurred only 0.15{+/- }0.070.15 days before our first detection. In the ∼24 hr after discovery, iPTF 16abc rose by ∼2 mag, featuring a near-linear rise in flux for ≳ 3 days. Early spectra show strong C II absorption, which disappears after ∼7 days. Unlike the extensively observed Type Ia SN 2011fe, the {(B-V)}0 colors of iPTF 16abc are blue and nearly constant in the days after explosion. We show that our early observations of iPTF 16abc cannot be explained by either SN shock breakout and the associated, subsequent cooling or the SN ejecta colliding with a stellar companion. Instead, we argue that the early characteristics of iPTF 16abc, including (i) the rapid, near-linear rise, (ii) the nonevolving blue colors, and (iii) the strong C II absorption, are the result of either ejecta interaction with nearby, unbound material or vigorous mixing of radioactive 56Ni in the SN ejecta, or a combination of the two. In the next few years, dozens of very young normal SNe Ia will be discovered, and observations similar to those presented here will constrain the white dwarf explosion mechanism.

    Abnormal uterine bleeding is one of the most common clinical problems in gynaecological practice and is an indicator of various underlying disorders. An endometrial biopsy should be done in all women over 35 years with AUB to rule out endometrial cancer or pre-malignant lesion and to initiate treatment. However, wide range of histological patterns on endometrial biopsy offer a diagnostic challenge to practicing pathologists. The objective of this study was to determine histological patterns of endometrium in postmenopausal women with abnormal uterine bleeding. This cross-sectional study was conducted in the department of obstetrics and gynaecology, Benazir Bhutto Shaheed women and children teaching hospital, Abbottabad from 15/11/2014 to 14/05/2015. This study involved 110 postmenopausal women presenting with abnormal uterine bleeding. A written informed consent was obtained from every patient. The mean age of the patients was 61.60±6.17 years and the mean duration of AUB was 5.20±2.80 years. Most of the patients were para 6 (28.2%) and para 5 (28.2%) followed by para 4 (18.2%) and para 3 (17.3%) while only 8.2% were para 1. The most common histological pattern observed was complex hyperplasia without atypia (30.9%) followed by atrophic endometrium (24.5%), simple hyperplasia (23.6%), malignancy (12.7%), complex hyperplasia with atypia (4.5%) and benign endometrial polyp (3.6%). When stratified the data, there was no significant difference of histological patterns across various age groups (p=.673), duration of AUB (p=.064) and parity (p=.242). The most common histological pattern observed in postmenopausal women with AUB was complex hyperplasia without atypia (30.9%) followed by atrophic endometrium (24.5%), simple hyperplasia (23.6%), malignancy (12.7%), complex hyperplasia with atypia (4.5%) and benign endometrial polyp (3.6%).

    Full Text Available Objectives: To assess the alveolar bone density by fractal dimension (FD analysis in radiovisiograph of postmenopausal women of mandibular posterior region and to correlate FD values with t-scores of quantitative ultrasound of the calcaneus bone. Materials and Methods: This study, approved by the institutional review board, included 40 participants, aged 45–60 years divided into two groups. Twenty postmenopausal women with osteoporosis comprised group 1, and 20 postmenopausal women without osteoporosis comprised group 2 based on bone mineral density assessment of ultrasound of the calcaneus bone. Digital dental radiograph of mandibular first molar were obtained and used for assessing alveolar bone density by FD analysis and were correlated with t-scores of ultrasound of calcaneus bone. Results: The mean FD values were evaluated using SPSS 14 version software, and were found to be 1.738 and 1.867 for group 1 and group 2, respectively, which was statistically significant (P 0.05. Conclusion: FD analysis using direct digital periapical radiographs is a novel method, which can be used for early diagnosis of osteoporosis in the alveolar bone.

    Operational research is required to design delivery of pre-exposure prophylaxis (PrEP) and early antiretroviral treatment (ART). This paper presents the primary analysis of programmatic data, as well as demographic, behavioural, and clinical data, from the TAPS Demonstration Project, which offered both interventions to female sex workers (FSWs) at 2 urban clinic sites in South Africa. The TAPS study was conducted between 30 March 2015 and 30 June 2017, with the enrolment period ending on 31 July 2016. TAPS was a prospective observational cohort study with 2 groups receiving interventions delivered in existing service settings: (1) PrEP as part of combination prevention for HIV-negative FSWs and (2) early ART for HIV-positive FSWs. The main outcome was programme retention at 12 months of follow-up. Of the 947 FSWs initially seen in clinic, 692 were HIV tested. HIV prevalence was 49%. Among those returning to clinic after HIV testing and clinical screening, 93% of the women who were HIV-negative were confirmed as clinically eligible for PrEP (n = 224/241), and 41% (n = 110/270) of the women who were HIV-positive had CD4 counts within National Department of Health ART initiation guidelines at assessment. Of the remaining women who were HIV-positive, 93% were eligible for early ART (n = 148/160). From those eligible, 98% (n = 219/224) and 94% (n = 139/148) took up PrEP and early ART, respectively. At baseline, a substantial fraction of women had a steady partner, worked in brothels, and were born in Zimbabwe. Of those enrolled, 22% on PrEP (n = 49/219) and 60% on early ART (n = 83/139) were seen at 12 months; we observed high rates of loss to follow-up: 71% (n = 156/219) and 30% (n = 42/139) in the PrEP and early ART groups, respectively. Little change over time was reported in consistent condom use or the number of sexual partners in the last 7 days, with high levels of consistent condom use with clients and low use with steady partners in both study groups.

    This is a review article designed to address the effects of soy isoflavones on bone metabolism in postmenopausal women and their place in the prevention and treatment of postmenopausal osteoporosis. Soy isoflavones are natural products that could be used as an alternative to menopausal hormone therapy because they are structurally and functionally related to 17beta-estradiol. In vitro and animal studies have shown that they act in multiple ways to exert their bone-supporting effects. They act on both osteoblasts and osteoclasts through genomic and nongenomic pathways. Epidemiological studies and clinical trials suggest that soy isoflavones have beneficial effects on bone mineral density, bone turnover markers, and bone mechanical strength in postmenopausal women. However, there are conflicting results related to differences in study design, estrogen status of the body, metabolism of isoflavones among individuals, and other dietary factors. The long-term safety of soy isoflavone supplements remains to be demonstrated.

    The aim of this study was to evaluate retrospectively the usefulness of transvaginal sonography for the detection of endometrial disease in postmenopausal women with bleeding. This study involved 275 postmenopausal women aged 47-81 years (median 62). None of them were on hormone replacement therapy and all had had amenorrhea for more than one year. Concerning the age of the study patients, we confirm that endometrial cancer occurs at any age, but more commonly in ages above 58 years. Transvaginal sonography was performed in all women. About 89.2% of malignant diseases were discovered in the study women whose endometrial thickness was above 4 mm, but we also found endometrial cancer in 10.2% of the cases in women whose endometrial thickness was below 4 mm. In postmenopausal symptomatic women premalignant or malignant causes of bleeding can not be excluded with just transvaginal ultrasound.

    Full Text Available Abstract Background Causes of the rapidly increasing incidence of breast cancer in Middle East and Asian countries are incompletely understood. We evaluated risk factors for postmenopausal breast cancer and estimated their attributable fraction in Iran. Methods We performed a hospital-based case–control study, including 493 women, diagnosed with breast cancer at 50 years or later between 2005–2008, and 493 controls. We used logistic regression models to estimate multivariable odds ratios (OR and 95% confidence intervals (CI, and population attributable fractions (PAF for significant risk factors. Results The risk of breast cancer decreased with increasing parity. Compared with nulliparous women, the adjusted OR (95% CI was 0.53 (0.25-1.15 for parity 1–3, 0.47 (0.29-0.93 for parity 4–6 and 0.23 (0.11-0.50 for parity ≥7. The estimated PAF for parity (25 was approximately 25%. The family history was significantly associated with increased breast cancer risk, but not increasing height, early age at menarche, late age at first birth or short breastfeeding. Conclusions Decreasing parity and increasing obesity are determinants of increasing breast cancer incidence among Iranian women. These trends predict a continuing upward trend of postmenopausal breast cancer.

    Full Text Available BACKGROUND: Walking speed seems to be related to aerobic capacity, lower limb strength, and functional mobility, however it is not clear whether there is a direct relationship between improvement in muscle strength and gait performance in early postmenopausal women. OBJECTIVE: To evaluate the effect of muscle strengthening exercises on the performance of the 6-minute walk test in women within 5 years of menopause. METHODS: The women were randomized into control group (n=31, which performed no exercise, and exercise group (n=27, which performed muscle strengthening exercises. The exercises were performed twice a week for 3 months. The exercise protocol consisted of warm-up, stretching, and strengthening of the quadriceps, hamstring, calf, tibialis anterior, gluteus maximus, and abdominal muscles, followed by relaxation. Muscular strength training started with 60% of 1MR (2 series of 10-15 repetitions, reaching 85% until the end of the 3-month period (4 series of 6 repetitions each. RESULTS: The between-group comparisons pre- and post-intervention did not show any difference in distance walked, heart rate or blood pressure (p>0.05, but showed differences in muscle strength post-intervention, with the exercise group showing greater strength (p CONCLUSION: The results suggest that muscle strengthening of the lower limbs did not improve performance in the 6-minute walk test in this population of postmenopausal women.

    Introduction:Hot flash is considered to be an early and common symptom of menopause. The present study aimed to determine the impact of black cohosh (Cimicifuga racemosa) on vasomotor symptoms in postmenopausal women. Methods:This was a randomized, double-blind, placebo-controlled clinical trial. This study was performed on 84 postmenopausal women. The participants were randomly divided into control and intervention groups. The participants of the intervention group received one black cohosh tablet per day and the control group received one placebo tablet per day for eight weeks. The severity of vasomotor symptoms and number of hot flashes were recorded during the pre-intervention phase, and 4 and 8 weeks after the intervention. The data were analyzed using repeated measures ANOVA and ANCOVA tests. The level of significance was considered lower than 0.05. Results:There was a significant difference between the two groups in terms of severity and number of hot flashes in weeks 4 and 8 by controlling the intensity of vasomotor symptoms and number of hot flashes before the intervention. Moreover, using repeated measures ANOVA, the intergroup comparison indicated a significant difference in bothgroups (the test and control groups) in terms of severity of vasomotor symptoms and number of hot flashes. Conclusion:According to the findings of the study, it seems that black cohosh can be used as an effective alternative medicine in relieving menopausal vasomotor symptoms. PMID:25276716

    The aim of the study was to evaluate panoramic radiograph, a commonly taken dental radiograph as a screening tool to detect early osseous changes (normal, mildly or severely eroded) of the mandibular inferior cortex and measure the mandibular cortical width (CW) in post-menopausal women and correlate it with the bone mineral density (BMD) measured by the ultrasound bone sonometer at the mid-shaft tibia region. The study included females between 45 years and 65 years of age in their post-menopausal stage (no menstruation for at least 6-12 months). Mandibular indices (mandibular CW and mandibular cortical shape) were evaluated from panoramic radiographs. The BMD assessment was carried out at the mid-shaft tibia region, exactly half-way between the heel and the knee joint perpendicular to the direction of the bone, using an ultrasound bone sonometer. It is a non-invasive device designed for quantitative measurement of the velocity of ultrasound waves as speed of sound in m/s, capable of measuring bone density at one or more skeletal sites. Using 1994 WHO criteria the study subjects were categorized as Group 1: Normal, Group 2: Osteopenia, Group 3: Osteoporosis. (WHO T score for tibia BMD can be used as a standard). The diagnostic efficacy of the panoramic radiograph in detecting osseous changes in post-menopausal women with low BMD was shown to have 96% specificity and 60% sensitivity with mandibular cortical shape and 58% specificity and 73% sensitivity with mandibular CW measurement. Factorial ANOVA analysis carried out indicated a significant correlation of BMD classification with mandibular cortical shape (F = 29.0, P panoramic radiograph are effective indicators of osteoporosis in post-menopausal women.

    Full Text Available BACKGROUND: Mammographic density is a strong risk factor for breast cancer. Apart from hormone replacement therapy (HRT, little is known about lifestyle factors that influence breast density. METHODS: We examined the effect of smoking, alcohol and physical activity on mammographic density in a population-based sample of postmenopausal women without breast cancer. Lifestyle factors were assessed by a questionnaire and percentage and area measures of mammographic density were measured using computer-assisted software. General linear models were used to assess the association between lifestyle factors and mammographic density and effect modification by body mass index (BMI and HRT was studied. RESULTS: Overall, alcohol intake was positively associated with percent mammographic density (P trend  = 0.07. This association was modified by HRT use (P interaction  = 0.06: increasing alcohol intake was associated with increasing percent density in current HRT users (P trend  = 0.01 but not in non-current users (P trend  = 0.82. A similar interaction between alcohol and HRT was found for the absolute dense area, with a positive association being present in current HRT users only (P interaction  = 0.04. No differences in mammographic density were observed across categories of smoking and physical activity, neither overall nor in stratified analyses by BMI and HRT use. CONCLUSIONS: Increasing alcohol intake is associated with an increase in mammography density, whereas smoking and physical activity do not seem to influence density. The observed interaction between alcohol and HRT may pose an opportunity for HRT users to lower their mammographic density and breast cancer risk.

    Background Menopausal hormone therapy (MHT) reportedly increases the risk of cognitive decline in women over age 65 y. It is unknown whether similar risks exist for recently postmenopausal women, and whether MHT affects mood in younger women. The ancillary Cognitive and Affective Study (KEEPS-Cog) of the Kronos Early Estrogen Prevention Study (KEEPS) examined the effects of up to 4 y of MHT on cognition and mood in recently postmenopausal women. Methods and Findings KEEPS, a randomized, double-blinded, placebo-controlled clinical trial, was conducted at nine US academic centers. Of the 727 women enrolled in KEEPS, 693 (95.3%) participated in the ancillary KEEPS-Cog, with 220 women randomized to receive 4 y of 0.45 mg/d oral conjugated equine estrogens (o-CEE) plus 200 mg/d micronized progesterone (m-P) for the first 12 d of each month, 211 women randomized to receive 50 μg/d transdermal estradiol (t-E2) plus 200 mg/d m-P for the first 12 d of each month, and 262 women randomized to receive placebo pills and patches. Primary outcomes included the Modified Mini-Mental State examination; four cognitive factors: verbal learning/memory, auditory attention/working memory, visual attention/executive function, and speeded language/mental flexibility; and a mood measure, the Profile of Mood States (POMS). MHT effects were analyzed using linear mixed-effects (LME) models, which make full use of all available data from each participant, including those with missing data. Data from those with and without full data were compared to assess for potential biases resulting from missing observations. For statistically significant results, we calculated effect sizes (ESs) to evaluate the magnitude of changes. On average, participants were 52.6 y old, and 1.4 y past their last menstrual period. By month 48, 169 (24.4%) and 158 (22.8%) of the 693 women who consented for ancillary KEEPS-Cog were lost to follow-up for cognitive assessment (3MS and cognitive factors) and mood evaluations

    Full Text Available BACKGROUND: Early signs of ischaemic stroke on computerised tomography (CT scanning are subtle but CT is the most widely available diagnostic test for stroke. Scoring methods that code for the extent of brain ischaemia may improve stroke diagnosis and quantification of the impact of ischaemia. METHODOLOGY AND PRINCIPAL FINDINGS: We showed CT scans from patients with acute ischaemic stroke (n = 32, with different patient characteristics and ischaemia signs to doctors in stroke-related specialties world-wide over the web. CT scans were shown twice, randomly and blindly. Observers entered their scan readings, including early ischaemic signs by three scoring methods, into the web database. We compared observers' scorings to a reference standard neuroradiologist using area under receiver operator characteristic curve (AUC analysis, Cronbach's alpha and logistic regression to determine the effect of scales, patient, scan and observer variables on detection of early ischaemic changes. Amongst 258 readers representing 33 nationalities and six specialties, the AUCs comparing readers with the reference standard detection of ischaemic signs were similar for all scales and both occasions. Being a neuroradiologist, slower scan reading, more pronounced ischaemic signs and later time to CT all improved detection of early ischaemic signs and agreement on the rating scales. Scan quality, stroke severity and number of years of training did not affect agreement. CONCLUSIONS: Large-scale observer reliability studies are possible using web-based tools and inform routine practice. Slower scan reading and use of CT infarct rating scales improve detection of acute ischaemic signs and should be encouraged to improve stroke diagnosis.

    Full Text Available Luigi Gennari, Daniela Merlotti, Vincenzo De Paola, Giuseppe Martini, Ranuccio NutiDepartment of Internal Medicine, Endocrine-Metabolic Sciences and Biochemistry, University of Siena, Policlinico Le Scotte 53100-Siena, ItalyAbstract: Bazedoxifene acetate is a novel, chemically distinct selective estrogen receptor modulator (SERM that has been specifically developed after a stringent preclinical screening in order to obtain favorable effects on the skeleton and lipid metabolism with the additional improvement of a neutral effect on hot flushes and without stimulating the uterus or the breast. In both preclinical and clinical studies this SERM was shown to maintain BMD, prevent fractures, and reduce total cholesterol. Moreover, bazedoxifene also showed an improved uterine profile and demonstrated estrogen antagonistic activity on the endometrium. Importantly, this latter capacity has led to the development of a novel class of menopausal therapy called tissue selective estrogen complex (TSEC, in which bazedoxifene is combined with conjugated estrogen. The rationale for selecting bazedoxifene as the SERM in this TSEC combination is that it may offset estrogen stimulation of endometrial and breast tissue, without the necessity of using a progestin in women with an intact uterus, without aggravating menopausal vasomotor symptoms, but with an additive effect on bone. Preliminary data from phase 3 clinical trials appear to confirm this hypothesis, showing a greater effect of bazedoxifene on BMD with respect to raloxifene, coupled with efficacy on menopausal vasomotor symptoms not achieved by SERM alone. These properties and the safety profile of this combination, if confirmed long-term in ongoing phase 3 trials, might significantly affect the way women and physicians approach menopause and its related disorders.Keywords: bazedoxifene, SERM, estrogen, postmenopausal osteoporosis, treatment

    To observe the clinical efficacy on pain in postmenopausal osteoporosis treated with the warm acupuncture therapy and discuss its effect mechanism. Ninety cases of postmenopausal osteoporosis were randomized into a warm acupuncture group, an electroacupuncture group and a medication group, 30 cases in each group. In the warm acupuncture group and the electroacupuncture group, Dazhu (BL 11), Shenshu (BL 23) and Xuanzhong (GB 39) were selected bilaterally and stimulated with the warm acupuncture and electroacupuncture therapies respectively, once a day for 30 days totally. In the medication group, caltrate-D tablets were prescribed, 600 mg, once a day for 30 days totally. The changes in the bone density T value, visual analogue scale (VAS) score, serum insulin like growth factor 1 (IGF-1), interleukin 6 (IL-6) and tumor necrosis factor (TNF-alpha) were observed before and after treatment in the three groups. (1) The bone density T value in the patients of postmenopausal osteoporosis did not change obviously after 30 days treatment with the three therapies; (2) VAS score was all reduced after treatment, in which, the result in the warm acupuncture group was the most obvious (6.73 +/- 0.24 before treatment vs 4.43 +/- 0.26 after treatment). The value after treatment in the warm acupuncture group was different significantly as compared with the electroacupuncture group (5.13 +/- 0.31) and the medication group (5.17 +/- 0.33, both P acupuncture therapy [(119.5 +/- 20.1) ng/mL before treatment vs (156.5 +/- 23.9) ng/mL after treatment], which was more apparent as compared with the electroacupuncture group [(136.3 +/- 24.5) ng/mL] and the medication group [(127.7 +/- 22.1) ng/mL, all P acupuncture group were superior to the other two groups (all P acupuncture therapy achieves the significant efficacy on pain in postmenopausal osteoporosis, which could be related to increasing the level of IGF-1, decreasing the levels of IL-6 and TNF-alpha, promoting bone formation and

    We previously reported that in the absence of hormone therapy (HT) or calcium/vitamin D (Ca/D) supplementation, earlier menopause age was associated with decreased bone mineral density and increased fracture risk in healthy postmenopausal women. Treatment with HT and Ca/D is protective against fractures after menopause. In this analysis, we asked if the age of menopause onset alters fracture risk in healthy postmenopausal women receiving HT, Ca/D, or a combination. Hazard ratios (HRs) for any fracture among 21,711 healthy postmenopausal women enrolled in the Women's Health Initiative Clinical Trial, who were treated with HT, Ca/D, or HT + Ca/D, and who reported age of nonsurgical menopause of menopause menopause 40 to 49 or ≥50 years, regardless of treatment intervention (HR [95% CI]: menopause menopause menopause age (menopause ages. The effect of menopause age on fracture risk was not altered by any of the treatment interventions (HT, Ca/D, HT + Ca/D), suggesting that early age of menopause is an independent contributor to postmenopausal fracture risk.

    The choices made by patients offered treatment for early laryngeal cancer with radiotherapy or transoral laser resection were reviewed. A prospective review was conducted of all patients diagnosed and treated for early laryngeal carcinoma from December 2002 to September 2009 at the Leeds Teaching Hospitals NHS Trust. A total of 209 patients with tumour stage T1 or T2 laryngeal cancer were treated; each new patient suitable for radiotherapy or transoral laser resection was seen jointly by the clinical (radiation) oncologist and head and neck surgeon, and offered the choice of treatment. Of the patients, 47.4 per cent were given a choice between radiotherapy and transoral laser resection; 51.2 per cent were advised to have radiotherapy, and there were no records for the remaining 1.4 per cent. From those given the choice, 59.6 per cent chose transoral laser resection (p radiotherapy. When given the choice, a statistically significant majority of patients choose transoral laser resection rather than radiotherapy.

    Three randomized trials (RCTs) in low-weight (BCG) vaccine nonspecifically reduces all-cause mortality in the neonatal period. Using data from 3 RCTs of early BCG (n = 6583) we examined potential sex differences in the timing of the mortality reduction in the neonatal period, presenting metaestimates of the main outcome mortality rate ratios (MRR) for BCG-vaccinated and controls. Among controls, boys had a particularly high mortality during the first week after randomization: male-female MRR 2.71 (95% CI, 1.70-4.50). During the first week, BCG had a marked beneficial effect for boys, reducing mortality 3-fold (MRR [BCG/no BCG] = 0.36 [0.20-0.67]). In weeks 2-4 the effect waned for boys (MRR = 0.91 [0.51-1.69]). In girls, the pattern was opposite with a limited effect in the first week (MRR = 0.85 [0.46-1.54]), but a significant reduction in weeks 2-4 (MRR = 0.56 [0.31-1.00]). This was consistent in all 3 trials. Verbal autopsies linked early benefit to fewer sepsis-related deaths among BCG-vaccinated boys. The marked reduction in mortality in the days after BCG vaccination in boys emphasizes the importance of providing BCG soon after birth.
