    1986-01-01

    A random sample of 151 Danish women who had undergone natural menopause reported the age at which this occurred and answered a questionnaire. A significant association was found between parity and age at menopause after correction for the effects of age at the first and last births, weight, smoking...... and occupation. However, there is no evidence that the age at menopause has fallen in recent decades, even though the average parity in developed populations has dropped dramatically over this period. It is therefore possible that potential fertility is a confounding variable in the relationship between parity...... and age at menopause....

    This cross-sectional study aimed to explore the relationship between menopause status and attitude toward menopause, and also its relationship with quality of life (QoL) of Chinese midlife women in Hong Kong. Hong Kong Chinese women aged 40 to 59 years were recruited through computer-generated random telephone dialing. Information was obtained through telephone interviews based on a structured questionnaire. Women were classified into 3 groups: premenopausal, perimenopausal, and postmenopausal. Menopause Belief Scale and Utian Quality of Life Scale (QoL) were used to measure respondents' attitude toward menopause and their QoL. Information on social, health, and lifestyle factors was also collected. The mean age of the participants was 49.4 ± 5.2 years. Respondents generally had a positive attitude toward menopause. Compared with premenopausal women, postmenopausal women were noted to have significantly higher attitude score toward menopause. No significant differences in QoL score were noted among women of the 3 menopause statuses. Stepwise regression analysis showed that women with more positive attitude toward menopause tended to have higher QoL score. Furthermore, better self-reported health status, doing physical activities, higher education level, being married, and non-smoking status were associated with better QoL. Postmenopausal women tended to have more positive attitude toward menopause. Although menopause status did not seem to be associated with QoL, attitude toward menopause, self-reported health status, as well as social and lifestyle factors were associated with QoL in Chinese midlife women.

    This study was conducted in order to identify the menopausal statues of Sudanese women which is critically important in determining the treatment strategy for infertile patients. In this study samples were collected from two hundred Sudanese women, aged between 35 and 62. They were from different social classes and are not suffering any systemic or endocrine disease. They were not exposed to any surgical intervention by complete hysterectomy or partial removal of ovaries or thyroidectomy. Reproductive hormones were determined for these women. Immunoradiometric Assay (IRMA) was adopted for the measurement of serum prolactin, follicle stimulating hormone, and luteinizing hormone. Enzyme linked immunosorbent assay (ELISA) was used for the determination of estradiol and esterone, whereas, enzyme immunoassay (tube format) was used for the determination of serum testosterone. Average menopausal age for Sudanese women was determined in this study and found to be 43.0±4.2 which is lower than that of the neighboring countries. A new classification system was developed during this study which uses a combination of symptoms together with hormonal profile in order to identify the menopausal status of women. The three key tools of this system are FSH and LH level together with the absence of menstrual cycle during the last three months. The new classification scheme had successfully differentiated the early peri-menopausal women from pre-menopausal ones. The early peri-menopausal women according to the new classification scheme are suffering cycle irregularities and amenorrhea but with normal hormonal levels. The new classification scheme is now, clearly indicating that amenorrhea with normal hormonal levels may be an indication to the beginning of the peri-menopausal life. The big challenge faced during this study had been the sub-classification of the peri-menopausal stage as it is not a single homogeneous stage but a wide heterogenous and transitional stage extending from

    The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n = 233), perimenopausal (n = 381), or postmenopausal (n = 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking speed, and 6-minute walking distance. PA level was assessed by self-report and categorized as low, moderate, or high. Multivariate linear regression modeling was used for data analysis. After including fat mass, height, PA, and education in the model, the postmenopausal women showed 12.0 N weaker (P women. There was no significant interaction between menopausal stage and PA on physical performance. The peri- and postmenopausal women with a high PA, however, showed better performance in the maximal knee extension strength and 6-minute walking test, and showed greater lower body muscle power than those with a low PA. Menopause status is associated with muscle strength and power, whereas the association between menopause status and mobility/walking is clearly weaker. A high leisure PA level provides more capacity to counteract the potential negative influence of menopausal factors on muscle function.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    In this contribution we briefly review the status of current searches for supersymmetry at the Large Hadron Collider, focusing especially on viable sub-TeV colored superpartners which can appear in nonstandard scenarios. The presented material covers mostly signals that do not crucially rely on the presence of large missing transverse momentum, with special emphasis on R-parity violating supersymmetry. For some scenarios the prospects for the next run of the Large Hadron Collider and future machines are also presented

    Background: In postmenopausal women, the two major causes of bone loss are oestrogen deficiency after menopause and age related processes. Bone turnover increases to high levels and oestrogen deficiency may induce calcium loss by indirect effects on extra skeletal calcium homeostasis. Objective of this study was to evaluate calcium status in pre-menopausal and postmenopausal women. Methods: This cross sectional study was carried out in 34 premenopausal women and 33 postmenopausal women, in Department of Physiology, Services Institute of Medical Sciences, Lahore. Height and weight of each woman were taken to find out the body mass index (BMI). Serum calcium, parathyroid hormone and calcitonin levels of each subject were determined. Results: Premenopausal women were obese (BMI>30 Kg/m/sup 2/) while postmenopausal women were overweight (BMI>25 Kg/m/sup 2/). Serum calcium levels were significantly lower in postmenopausal women than in pre-menopausal women, while serum parathyroid hormone levels were significantly higher in postmenopausal woman. Serum calcitonin level was not significantly different in the two groups. Conclusion: Postmenopausal women are calcium deficient and have increased bone turnover as indicated by increased serum parathyroid hormone levels. (author)

    The present study investigated the prevalence and severity of menopause symptoms experienced by Korean women aged 44 to 56 years and their associated factors. A cross-sectional study was performed on 2,201 women aged 44 to 56 years in health checkup centers between November 2012 and March 2013. The 29-item Menopause-Specific Quality of Life Questionnaire was used to assess vasomotor, psychosocial, physical, and sexual symptoms related to menopause. The guidelines for the classification of reproductive aging stages proposed at the Stages of Reproductive Aging Workshop were used. Multivariable linear regression analyses were performed to identify factors associated with severity of menopause symptoms. Among participants, 42.6% were premenopausal, 36.7% were perimenopausal, and 20.7% were postmenopausal. Although physical symptoms were the most severe menopause symptoms experienced by premenopausal and perimenopausal women, postmenopausal women reported sexual symptoms as the most bothersome. The mean scores for each domain increased from the premenopausal period through the postmenopausal period (P for trend menopause symptoms (P menopause than inactive women. Postmenopausal women experience the most severe symptoms. Obesity and physical activity are the main modifiable factors associated with symptom severity. Further studies are needed to examine the effects of physical activity promotion and weight control interventions on preventing menopause symptoms in Korean women.

    1980-11-01

    Comparisons between oestrogen-receptor (RE)-positive or negative patients were made on a continuous series of 735 patients with primary breast tumours seen at the major treatment centre in British Columbia between 1975 and 1978. RE positivity was commoner in older patients, and was not associated with menopausal status independently of age. The concentration of receptor protein also increased with increasing age, but was not affected by menopausal status. Neither RE status nor quantity was associated with any of the epidemiological risk factors studied, which included parity, age at first birth, weight, family history and exposure to oestrogenic drugs and oral contraceptives. Patients with RE- tumours were more likely to present with symptoms other than a breast lump, pain or nipple inversion, and had less-differentiated tumours; they did not differ from RE+ patients in terms of stage, size of tumour, or interval from first symptom. These findings are discussed in terms of the biological origin and determinants of oestrogen receptors.

    To determine the influence of reproductive history on the prevalence of obesity in Brazilian women and the possible modifying effect of socioeconomic variables on the association between parity and excess weight. A retrospective analysis of complex sample data collected as part of the 2006 Brazilian National Survey on Demography and Health, which included a group representative of women of childbearing age in Brazil was conducted. The study included 11 961 women aged 20 to 49 years. The association between the study factor (parity) and the outcome of interest (obesity) was tested using logistic regression analysis. The adjusted effect of parity on obesity was assessed in a multiple regression model containing control variables: age, family purchasing power, as defined by the Brazilian Association of Research Enterprises (ABEP), schooling, and health care. Significance level was set at below 0.05. The prevalence of obesity in the study population was 18.6%. The effect of parity on obesity was significant (P for trend parity and age. Family purchase power had a significant odds ratio for obesity only in the unadjusted analysis. In the adjusted model, this variable did not explain obesity. The present findings suggest that parity has an influence on obesity in Brazilian women of childbearing age, with higher prevalence in women vs. without children.

    To evaluate the effect of menopausal status on the background parenchymal enhancement (BPE) and amount of fibroglandular tissue (FGT) on breast MRI. Retrospective review identified 1,130 women who underwent screening breast MRI between July and November 2010. In 28 of these women, breast MRI was performed both at one time point while pre- and one time point while post-menopausal (median interval 49 months). Two independent readers blinded to menopausal status used categorical scales to rate BPE (minimal/mild/moderate/marked) and FGT (fatty/scattered/heterogeneously dense/dense). Consensus was reached when there was disagreement. The sign test was used to assess changes in rating categories, and the Spearman rank and Fisher's exact tests were used to measure correlations and associations between variables. Significant proportions of women demonstrated decreases in BPE and FGT on post-menopausal breast MRI (P = 0.0001 and P = 0.0009). BPE category was unchanged in 39 % (11/28) and decreased in 61 % (17/28) of women. FGT category was unchanged in 61 % (17/28) and decreased in 39 % (11/28) of women. Age, reason for menopause, or interval between MRIs had no significant impact on changes in BPE and FGT. On MRI, BPE, and FGT decrease after menopause in significant proportions of women; BPE decreases more than FGT. (orig.)

    Objective: Females with different menopausal status are compared for serum lipids to explore the role of menopausal status in developing gallstones. Methodology: This study was conducted at Institute of Biochemistry, University of Sindh Jamshoro, Pakistan. A total number of 135 female gallstone patients admitted at Liaquat University Hospital, Wali Bhai Rajputana Hospital, Hyderabad and other hospitals of Hyderabad, Pakistan and 170 age and gender matched control subjects were selected for the study. The serum samples of patients of different menopausal status and control group were analyzed for the lipid contents. Gallstones recovered from the patients were also analyzed for the composition by FTIR. Results: Serum total cholesterol (TC) and serum high density lipoprotein cholesterol (HDL-C) were significantly varied among all age groups while serum triglycerides (TG), serum very low density lipoprotein cholesterol (VLDL-C) and serum total lipids (TL) were found to be significantly differed among four different types of gallstone formers. Consumers of non-branded oil and non-branded ghee were found with significant lipid alterations in comparison to control group. Major lipid alterations were found in female gallstone patients with pre and peri-menopause. Conclusion: Raised serum TC, serum TG and decreased serum HDL-C in addition to pre- and peri-menopausal status may be considered as biomarkers for female gallstone patients.

  18. Littlest Higgs with T-parity. Status and prospects

    2013-11-15

    The Littlest Higgs model with T-parity is providing an attractive solution to the fine-tuning problem. This solution is only entirely natural if its intrinsic symmetry breaking scale f is relatively close to the electroweak scale. We examine the constraints using the latest results from the 8 TeV run at the LHC. Both direct searches and Higgs precision physics are taken into account. The constraints from Higgs couplings are by now competing with electroweak precision tests and both combined exclude f up to 694 GeV. At the same time limits from direct searches now become competitive and constrain f to be larger than 638 GeV. We show that the Littlest Higgs model parameter space is slowly driven into the TeV range. Furthermore, we develop a strategy on how to optimise present supersymmetry searches for the considered model, with the goal to improve the constraints and yield more stringent limits on f.

    Aim: The present study is aimed to use bone mineral density (BMD) and various biochemical markers to predict the fracture risk at different menopausal statuses in Pakistani women. Method: Seventy women aged between 28-80 years at various menopausal statuses participated in this study. BMD (T score) of right calcaneus was determined using SAHARA ultrasound bone densitometer that measures the transmission of high frequency from heel. Various biochemical markers such as alkaline phosphates, calcium and inorganic phosphorus were measured from the serum of venous blood using standard kits of Randox. Results: Alkaline phosphates was raised in per menopausal, postmenopausal and postmenopausal with hysterectomy and ligation groups of women as compared to premenopausal women but did not achieve significance (P>0.05). Serum calcium level was significantly lower in postmenopausal women than premenopausal women and inorganic phosphorus decrease significantly when compared with premenopausal and postmenopausal with ligation and hysterectomy. BMD (T score) values of postmenopausal osteopenic and postmenopausal osteoprotic women were significantly lower than those of premenopausal women. BMD values of women under study have negative correlation with age, alkaline phosphates and calcium. Conclusion: Our study conclude that in addition to BMD, serum levels of alkaline phosphate, calcium and inorganic phosphorus can be valuable biochemical markers in predicting bone fracture risk at different menopausal states.

    The aim of this study was to determine whether postmenopause status is associated with self-reported limitations in physical function. The Study of Women's Health Across the Nation is a multisite, multiethnic, longitudinal study of midlife women. Women aged 45 to 57 years (N = 2,566) completed the physical function scale of the Medical Outcomes Study Short-Form 36 on visit 4 (2000-2001). Scores created a three-category variable of physical function limitations: none (86-100), moderate (51-85), and substantial (0-50). In the Study of Women's Health Across the Nation, menopause status is a five-category list variable based on menstrual bleeding patterns and gynecological surgery. Premenopausal and perimenopausal women using hormones (n = 284) or missing physical function scores (n = 46) were excluded. Multinomial logistic regression was used to relate physical function and menopause status after adjustment for age, ethnicity, site, education, body mass index (BMI), and self-reported diabetes, hypertension, arthritis, depressive symptoms, smoking, and hormone use among postmenopausal women. Of 2,236 women, 8% were premenopausal, 51% were early perimenopausal, 12% were late perimenopausal, 24% were naturally postmenopausal, and 5% were surgically postmenopausal. In the full model, substantial limitations in physical function were higher in postmenopausal women, whether naturally postmenopausal (odds ratio, 3.82; 95% CI, 1.46-10.0) or surgically postmenopausal (odds ratio, 3.54; 95% CI, 1.15-10.84), than in premenopausal women. These associations were attenuated by higher BMI and depressive symptoms but remained significant. Moderate limitations in physical function were not significantly related to menopause status. Women experiencing surgical or naturally occurring postmenopause report greater limitations in physical function compared with premenopausal women, independent of age and only partly explained by higher BMI and depressive symptoms. This suggests that

    The association between mild renal dysfunction and bone mineral density (BMD) has not been fully explored. It is also unclear how menopausal status and the use of Chinese herb affect this association. This is a cross-sectional study that included a total of 1,419 women aged 40 to 55 years old who were recruited from the MJ Health Management Institution in Taiwan between 2009 and 2010. Spinal BMD was assessed by dual-energy X-ray absorptiometry. Renal function was assessed using estimated glomerular filtration rate (eGFR) and creatinine clearance rate (CCr). The multivariable logistic regression and general linear models were employed to assess the association between renal function and BMD. Stratification analyses were performed by menopausal status and use of Chinese herbs. Low CCr levels were significantly associated with low BMD [adjusted odds ratio (AOR) = 1.48, 95% confidence interval (CI) = 1.15-1.90]. This association was observed in premenopausal women (AOR = 1.43, 95% CI = 1.07-1.92) and in women not taking Chinese herbs (AOR = 1.48, 95% CI = 1.14-1.94). CCr is a better predictor for low BMD in middle-aged women. Menopausal status and the use of Chinese herbs also affected this association.

    Full Text Available Abstract Background It is a well accepted status that socio-cultural characteristics may affect the onset of menopause and its characteristics. The aims of this study were to describe the prevalence rates of menopausal symptoms and these symptoms related factors, and to assess the women's attitudes towards some climacteric issues. Methods This survey was conducted between Jan., 1st 2008 and March, 31st 2008 to research the menopause status of the female population in a city of western Turkey. The study group consisted of 1551 women selected with a multistage area sampling method: a random sample of individuals aged 40-65 years. The questionnaire included questions pertaining to women's sociodemographic characteristics, women's menopausal status, some statements about the climacteric, use of hormones at menopause or before menopause, and some climacteric myths. The data was analyzed by Chi-square (x2 analysis and percent (% ratios with a significant value of P Results The mean age of the women was 49.1 years. Over 90% of the women were of the negative opinion that the climacteric is "the end of youth", "the end of fecundity", and "the end of unclean days". Most women said that cessation of menstrual periods was the most positive thing because they do not have to wait for monthly bleedings, use sanitary equipment, or take birth control methods. There were significant connections between age groups and nearly all the items, with the exception of the items "the end of life" and "the end of fecundity". Among the women, hot flushes were the most common complaint occurring in 96.5% of women: being severe in 32.9%, moderate in 43.1% and mild in 20.4%. This was followed by low backache or muscle pain 95.0% (25.9% severe, 46.0% moderate and mild 23.1%, headache 91.7% (21.9% severe, 34.9% moderate and 34.9% mild and feeling tired 91.0% (15.3% severe, 38.6% moderate and 37.1% mild. Conclusions Most of the women in this study had mixed ideas of opinions

    Mammography dose increases with compressed breast thickness (CBT), but few studies have examined other correlates of dose. The purpose of this study was to evaluate the relation between factors such as race, age, body mass index (BMI), CBT, and menopausal status and mammography screening dose, measured for 509 women in a US population. A multiple linear regression model was developed for dose, based on consideration of these factors as well as examination characteristics. BMI and number of films during examination were positively related to dose. After adjusting for these factors, high CBT also leads to higher dose. Whites receive lower doses than black women, but differences are slight after controlling for the effects of CBT and BMI, which were significantly higher among black women. Pre-menopausal women receive higher doses, after adjusting for all other factors, than post-menopausal women. Jointly, these factors account for approximately 75% to 80% of the variability in dose among this study population. Because rates of overweight are increasing in the US, average doses from mammography may be increasing as well. (author)

    , should show little or no preference when choosing mating partners (e.g. should mate indiscriminately).

    It is important to identify modifiable risk factors for breast cancer, because the breast cancer is one of the major cause of mortality among women. Some reported that obesity is a risk factor for breast cancer, but the results are not constant. Many risk factors are related to the duration of estrogenic stimulation of the breast. In general, early menarche and late menopause are positive risk factors. Human breast cancer has different characteristics according to the status of menopause (premenopause and postmenopause). In premenopausal women, about 60% of circulating estrogen is from the ovaries in the form of estradiol, and the remaining 40% is estrogen formed primarily in the adipose(fat) tissue via aromatization of androstenedion from the adrenal glands. After menopause this adipose cell production of estrone is the maon source of estrogens and the level of estrone is maintained approximately at premenopausal levels. This study was undertaken to determine the role of body size and body mass index by status of menopause in development of breast cancer using retrospective case/control study. From Mach 1991 to February 1997 at the Wonkwang University Hospital, the breast cancer cases(n=3D72) and controls(n=3D86) were selected. By statistical analysis method, regression analysis, paired T-test and multiple logistic regression were done to estimate the influenced factors same as height, weight, BMI, age at menarche and age at menopause. The following results were obtained: 1. In premenopausal women, age at menarche was showed comparatively high correlation coefficients and BMI was described prominently highly in postmenopause. 2. At the results of multiple regression analysis, age at menarch, BMI and weight were showed as significant variables. In this method, critical facor(R{sup 2}) was 0.054. 3. Paired samples T-test was undertaken to test mean difference between two groups of cases and controls. The result of test performance showed a significant difference. 4

    Gender medicine requires a global analysis of an individual's life. Menopause and ageing induce variations of some cardiometabolic parameters, but, it is unknown if this occurs in a sex-specific manner. Here, some markers of oxidative stress, systemic inflammation, and endothelial dysfunction are analysed in men younger and older than 45 years and in pre- and postmenopausal women. Serum and plasma sample were assayed for TNF-α and IL-6, malondialdehyde and protein carbonyls and for methylated arginines using ELISA kits, colorimetric methods and capillary electrophoresis. Before body weight correction, men overall had higher creatinine, red blood cells and haemoglobin and lower triglycerides than women. Men younger than 45 years had lower levels of TNF-α and malondialdehyde and higher levels of arginine than age-matched women, while postmenopausal women had higher IL-6 concentrations than men, and higher total cholesterol, triglycerides, creatinine and IL-6 levels than younger women. Men younger than 45 years had lower total cholesterol and malondialdehyde than older men. After correction, some differences remained, others were amplified, others disappeared and some new differences emerged. Moreover, some parameters showed a correlation with age, and some of them correlated with each other as functions of ageing and ageing/menopausal status. Ageing/menopausal status increased many more cardiovascular risk factors in women than ageing in men, confirming that postmenopausal women had increased vascular vulnerability and indicating the need of early cardiovascular prevention in women. Sex-gender differences are also influenced by body weight, indicating as a matter of debate whether body weight should be seen as a true confounder or as part of the causal pathway.

    The basis of the G 0 experiment is a parity-violating process giving access to the strange form factors of the proton. It requires the measurement of a set of asymmetries, in elastic electron scattering from hydrogen and quasi-elastic scattering from deuterium, at different Q 2 and at different angles. The experimental site is the Thomas Jefferson National Accelerator Facility (J Lab.), Newport News, VA (USA). The formalism that connects asymmetries with the proton properties at the quark level, the experimental set-up and the present status are described. A section is devoted to a special electronic module, built at the IPN-Orsay, using Digital Signal Processors (DSPs)

    Background We investigated whether there were gender differences in the effect of obesity on bone mineral density (BMD) based on menopausal status. Methods We assessed 5,892 consecutive patients 20 to 91 years old who were referred for dual-energy X-ray absorptiometry (DXA) scans. All subjects underwent a standard BMD scan of the hip (total hip and femoral neck) and lumbar spine (L1 to L4) using a DXA scan and body size assessment. Body mass index was used to categorize the subjects as normal weight, overweight, and obese. Results BMD was higher in obese and overweight versus normal weight men, premenopausal women, and postmenopausal women. Compared to men ≥50 years and postmenopausal women with normal weight, the age-adjusted odds ratio of osteopenia was 0.19 (95% confidence interval [CI], 0.07 to 0.56) and 0.38 (95% CI, 0.29 to 0.51) for obese men ≥50 years and postmenopausal women. Corresponding summaries for osteoporosis were 0.26 (95% CI, 0.11 to 0.64) and 0.15 (95% CI, 0.11 to 0.20), respectively. Compared to men obese men Obesity is associated with BMD of the hip and lumbar spine and overweight and obese individuals have similar degrees of osteoporosis. This result was not significantly different based on gender and menopausal status, which could be an important issue for further investigation. PMID:27834082

    Several studies have shown that parity is associated with oral health problems such as tooth loss and dental caries. In Japan, however, no studies have examined the association. The purpose of this study was to determine whether parity is related to dentition status, including the number of teeth present, dental caries and filled teeth, and the posterior occlusion, in a Japanese population by comparing women with men. A total of 1,211 subjects, who participated both in the Japan Public Health Center-Based (JPHC) Study Cohort I in 1990 and the dental survey in 2005, were used for the study. Information on parity or number of children was collected from a self-completed questionnaire administered in 1990 for the JPHC Study Cohort I, and health behaviors and clinical dentition status were obtained from the dental survey in 2005. The association between parity or number of children and dentition status was analyzed, by both unadjusted-for and adjusted-for socio-demographic and health behavioral factors, using a generalized linear regression model. Parity is significantly related to the number of teeth present and n-FTUs (Functional Tooth Units of natural teeth), regardless of socio-demographic and health behavioral factors, in female subjects. The values of these variables had a significantly decreasing trend with the rise of parity: numbers of teeth present (p for trend = 0.046) and n-FTUs (p for trend = 0.026). No relationships between the number of children and dentition status were found in male subjects. Higher-parity women are more likely to lose teeth, especially posterior occluding relations. These results suggest that measures to narrow the discrepancy by parity should be taken for promoting women's oral health. Delivery of appropriate information and messages to pregnant women as well as enlightenment of oral health professionals about dental management of pregnant women may be an effective strategy.

    Forty two healthy Egyptian women were participated in this study to evaluate the effect of early and late menopause on some biochemical and hormonal parameters. The women were divided into three equal groups. The first was the pre-menopausal group with regular menstrual cycle, the second was the late menopausal group comprised the menopausal female less than 5 years and the third group consisted of women that became menopause since 5-9 years. The second and third groups had almost the same age and body weight. After clinical examination, fasting blood samples were collected from all volunteers. Regarding the pre-menopausal women, blood was withdrawn between the 3 rd and the 5 th day post-menstruation (follicular phase). Follicle stimulating hormone (FSH), leutinizing hormone (LH), progesterone, prolactin (PRL), testosterone, leptin and thyroxine (T4) in addition to hemoglobin (Hb), blood glucose, calcium (Ca), inorganic phosphorous (P), magnesium (Mg) and uric acid were determined. Both menopausal groups showed significant increase in FSH and LH and significant decrease in PRL and late menopausal group experienced also multiple significant correlations between FSH, LH and other tested parameters. Prolongation of menopause exhibited decrease in leptin being significant as compared to pre-menopausal women than that experienced menopause at younger age. Due to the relation between leptin hormone and osteoporosis, the results of this investigation denoted that early cessation of annulations (menopause) in Egyptian women may lead to disturbance in bone metabolism causing inhibiting osteoblastogenesis and decreasing bone mass.

    Information on the metastasis process in breast cancer patients undergoing primary tumour removal may be extracted from an analysis of the timing of clinical recurrence. The hazard rate for local-regional and/or distant recurrence as the first event during the first 4 years after surgery was studied in 1173 patients undergoing mastectomy alone as primary treatment for operable breast cancer. Subset analyses were performed according to tumour size, axillary nodal status and menopausal status. A sharp two-peaked hazard function was observed for node-positive pre-menopausal patients, whereas results from node-positive post-menopausal women always displayed a single broad peak. The first narrow peak among pre-menopausal women showed a very steep rise to a maximum about 8–10 months after mastectomy. The second peak was considerably broader, reaching its maximum at 28–30 months. Post-menopausal patients displayed a wide, nearly symmetrical peak with maximum risk at about 18–20 months. Peaks displayed increasing height with increasing axillary lymph node involvement. No multi-peaked pattern was evident for either pre-menopausal or post-menopausal node-negative patients; however, this finding should be considered cautiously because of the limited number of events. Tumour size influenced recurrence risk but not its timing. Findings resulting from the different subsets of patients were remarkably coherent and each observed peak maintained the same position on the time axis in all analysed subsets. The risk of early recurrence for node positive patients is dependent on menopausal status. The amount of axillary nodal involvement and the tumour size modulate the risk value at any given time. For pre-menopausal node-positive patients, the abrupt increase of the first narrow peak of the recurrence risk suggests a triggering event that synchronises early risk. We suggest that this event is the surgical removal of the primary tumour. The later, broader, more symmetrical risk

    Copulation preferences in our closest living relative, the chimpanzee, suggest that males prefer older females who have had previous offspring. However, this finding is counter to some behavioral models, which predict that chimpanzee males, as promiscuous breeders with minimal costs to mating, should show little or no preference when choosing mating partners (e.g. should mate indiscriminately). To determine if the preferences indicated by copulations appear in other contexts as well as how they interact, we examined how male chimpanzees' grooming patterns varied amongst females. We found that males' preferences were based on interactions among females' fertility status, age, and parity. First, grooming increased with increasing female parity. We further found an effect of the estrous cycle on grooming; when females were at the lowest point of their cycle, males preferentially groomed parous females at peak reproductive age, but during maximal tumescence, males preferred the oldest multiparous females. Nulliparous females received relatively little grooming regardless of age or fertility. Thus, male chimpanzees apparently chose grooming partners based on both female's experience and fertility, possibly indicating a two-pronged social investment strategy. Male selectivity seems to have evolved to effectively distribute costly social resources in a pattern which may increase their overall reproductive success. © 2011 Wiley-Liss, Inc.

These results indicate that the parity-status has an impact on the outcome of studies aiming at the investigation of estrogenic effects of compounds potentially used in hormone replacement and thus, this should be taken into consideration for further studies and particularly for the discussion of data obtained with the preclinical ovariectomized rat animal model.

    Full Text Available Aim. Urinary tract infection (UTI is considered one of the most common bacterial infections in women. The aim of this study was to investigate the types of uropathogens present, as well as the degree of antimicrobial drug resistance seen among premenopausal (n=2748 and postmenopausal (n=1705 women with uncomplicated UTI. Methods. Urinary samples (n=4453 collected from women with UTI were analyzed in terms of uropathogens present. These were considered as positive if bacterial growth was ≥105 colony forming units (CFUs/mL. Susceptibility and resistance testing for commonly used antibiotics was subsequently assessed. Results. The most common uropathogens cultured from urine samples were Escherichia coli (65.5%, followed by Enterococcus faecalis (12.2%, Klebsiella pneumoniae (4.7%, and Proteus mirabilis (4.2%. The resistance to ampicillin exceeded 40%, independently of menopausal status. Of note, resistance to ciprofloxacin exceeded 25% among postmenopausal patients. Moreover, resistance of all uropathogens to commonly used antimicrobials was significantly higher in postmenopausal women. Conclusion. Due to the high resistance rate, ampicillin, ciprofloxacin, and the trimethoprim/sulfamethoxazole combination should be avoided in treating postmenopausal women affected by UTI without being indicated by initial urine culture report. Finally, cephalexin and cefuroxime are promising alternatives as initial treatment in postmenopausal women.

    Full Text Available OBJECTIVES: cigarette smoking has been the modifiable risk factor most consistently associated with earlier menopause. This preliminary study based on cross-sectional data aimed to analyze the association between smoking status and age of onset of menopause in a Brazilian population. METHODS: a cross-sectional study was carried out with 1,222 female employees of Rio de Janeiro university campuses aged over 35 years who were at risk of natural menopause. A Cox proportional hazards model was used to investigate the association between smoking status and age at the onset of menopause, adjusting for education, parity and alcohol consumption. RESULTS: current smokers showed a 56% increase in the risk of menopause, being 1.8 years younger at menopause onset compared with women who had never smoked. However, no differences were observed between former smokers and women who had never smoked. The adjusted median age at menopause was 49.5 years for current smokers and 51.3 years for women who had never smoked (p<0.05. CONCLUSIONS: the results suggest a deleterious but potentially reversible effect of smoking on the age of onset of menopause, which should receive greater attention in tobacco control efforts. Longitudinal analyses of this association will be carried out in the future in a follow-up study of this population.

    The detection and estimation of skeletal calcium loss has become an important consideration in the management of post-menopausal women. The need to supplement large amounts of calcium of 1000-1500 mg per day is recommended to forestall the risk of skeletal fractures. The added supplementation of estrogens and progesterone for several years is also recommended to prevent bone calcium loss. The need to record the calcium status in post-menopausal women is becoming necessary in the present scenario. A total of 159 women in the peri-menopausal, menopausal and post-menopausal groups were selected. None of them had other systemic diseases. They were healthy and not on any medication. They were randomly grouped into 3 groups. One was considered as control and no medication was advised. The second group was advised 1000-1500 mg of calcium carbonate daily. The third group was given the same dose of calcium, but also received additionally another 2 mg of estradiol daily. Whole Body Retention (WBR) studies of Tc-99m MDP were carried out before starting treatment and at 6 monthly intervals for a period of 5 years. Serum calcium and alkaline phosphatase were estimated on fasting samples at the start of the study and at every 6 monthly intervals. WBR studies were done using a shadow shield whole body counter attached with a 5 inch diameter sodium iodide crystal detector and a 5 mm wide slit collimator. The WBR of Tc-99m MDP at 24 hours was found to be 27.55 ± 6.76% in women in the peri-menopausal age range of 25-45 years. It was also observed that at the time of menopause 13.3% of the women had WBR values above 2 SD of the normal values. This suggests that calcium loss from the skeleton is present only in a small number of women at menopause. However in women who were not supplemented with calcium or subjected to hormonal and calcium treatment, the number of women who showed loss of bone calcium increased within a period of 1-2 years after menopause. This simple method of WBR

  1. Myeloperoxidase polymorphism, menopausal status, and breast cancer risk: an update meta-analysis.

    Directory of Open Access Journals (Sweden)

    Xue Qin

    Full Text Available Myeloperoxidase (MPO is a metabolic/oxidative lysosomal enzyme secreted by reactive neutrophils at the sites of inflamed organs and tissues during phagocytosis. MPO has been either directly or indirectly linked to neoplasia, which is a well-established risk factor for many types of cancer. A large number of studies have reported the role of MPO G-463A polymorphism regarding breast-cancer risk. However, the published findings are inconsistent. Therefore, we conducted a meta-analysis to determine more precise estimations for the relationship. Eligible studies were identified by searching several electronic databases for relevant reports published before June 2012. According to the inclusion criteria and exclusion criteria, a total of five eligible studies were included in the pooled analyses. When the five eligible studies concerning MPO G-463A polymorphism were pooled into this meta-analysis, there was no evidence found for a significant association between MPO G-463A polymorphism and breast-cancer risk in any genetic model. We also categorized by ethnicity (Caucasian or Asian for subgroup analysis; according to this subgroup analysis, we found no significant association between MPO G-463A polymorphism and breast-cancer risk in any genetic model. However, in the stratified analysis for the premenopausal group, women carrying the AA genotype were found to have a significantly reduced risk (OR = 0.56, 95% CI 0.34-0.94, p = 0.027. Under the recessive model, there was a significant association between MPO G-463A polymorphism and breast-cancer risk (OR = 0.57, 95% CI 0.34-0.93, p = 0.025. We conclude that MPO-G463A polymorphism might not be a good predictor of breast-cancer risk, though menopausal status modified women's risk of developing breast cancer.

    Bone density in different regions of the skeleton was measured in 392 normal women aged 20-80 years by dual photon absorpiometry. In premenopausal women, aged 25-50 years, multiple regression analysis of regional bone density on age, height, and weight showed a small significant decrease in total bone density (less than 0.01) but no significant change in other regions of the skeleton. In postmenopausal women there were highly significant decreases in all regions of the skeleton (p less than 0.001), and bone density in these areas decreased as a logarithmic function of years since menopause. Based on multiple regression analyses, the decrease in spine density and total bone calcium was 2.5-3.0 times greater in the 25 years after menopause than the 25 years before menopause. The largest change, however, occurred in the first five years after menopause. During this time the estimated annual change in spine density and total bone calcium was about 10 times greater than that in the premenopausal period. These results demonstrate the important effect of the menopause in determining bone mass in later life

    There are limited data for age at menopause (AM) and menopause-related symptoms in human immunodeficiency virus (HIV)-infected Asian women. We investigated AM and menopause-related symptoms in HIV-infected Thai women. HIV-infected Thai women 40 years or older who did not receive any hormone therapy in the 8-week period preceding the study were enrolled. Participants completed the Menopause-Specific Quality of Life survey for their symptoms in the past 30 days. Menopause was defined as having the last menstrual period more than 1 year ago. Multivariate Cox proportional hazard regression analysis was used to identify factors associated with menopause. Two hundred sixty-eight HIV-infected women were enrolled; their median age was 44.6 (41.8-48.7) years, and the ratio of their Centers for Disease Control and Prevention clinical classifications (A:B:C) was 53%:34%:13%; 95% were using highly active antiretroviral therapy. The median (interquartile range [IQR]) CD4 count was 575 (437-758) cells/μL, and 93% had HIV-RNA of less than 1.7log10 copies/mL. Among the 55 women who had reached menopause, the mean (SD) AM was 47.3 (5.1) years. The mean (SD) AM in our study was earlier than the previous report of 49.5 (3.6) years in non-HIV-infected Thai women (difference, -2.2 y; 95% CI, -3.2 to -1.2, P menopause were Centers for Disease Control and Prevention clinical classification B or C (hazard ratio, 1.7; 95% CI, 1.0-3.03, P = 0.04), and no sexual act in the past month (hazard ratio, 4.9; 95% CI, 1.5-16.0, P = 0.01). No associations of later age of menarche, parity, marital status, educational level, income, body mass index, CD4 count, and HIV-RNA with menopause were found. AM in HIV-infected Thai women was 47.3 years, which is significantly earlier than the findings of a previous AM report on non-HIV-infected women. Postmenopausal HIV-infected women had more vasomotor and sexual symptoms. More studies are needed to investigate the cause and appropriate interventions for

    Objective The purpose of this study was to develop a risk prediction score for distinguishing benign ovarian mass from malignant tumors using CA-125, human epididymis protein 4 (HE4), ultrasound findings, and menopausal status. The risk prediction score was compared to the risk of malignancy index and risk of ovarian malignancy algorithm (ROMA). Methods This was a prospective, multicenter (n=6) study with patients from six Asian countries. Patients had a pelvic mass upon imaging and were scheduled to undergo surgery. Serum CA-125 and HE4 were measured on preoperative samples, and ultrasound findings were recorded. Regression analysis was performed and a risk prediction model was developed based on the significant factors. A bootstrap technique was applied to assess the validity of the HE4 model. Results A total of 414 women with a pelvic mass were enrolled in the study, of which 328 had documented ultrasound findings. The risk prediction model that contained HE4, menopausal status, and ultrasound findings exhibited the best performance compared to models with CA-125 alone, or a combination of CA-125 and HE4. This model classified 77.2% of women with ovarian cancer as medium or high risk, and 86% of women with benign disease as very-low, low, or medium-low risk. This model exhibited better sensitivity than ROMA, but ROMA exhibited better specificity. Both models performed better than CA-125 alone. Conclusion Combining ultrasound with HE4 can improve the sensitivity for detecting ovarian cancer compared to other algorithms. PMID:25310857

The women are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. There is need to use simplified protocols and improved techniques in oocyte donation to achieve pregnancy and mother a baby in those women at risk. Review of the pertinent literature on premature menopause, selected references, internet services using the PubMed and Medline databases were included in this review. In the past, pregnancy in women with premature menopause was rare but with recent advancement in oocyte donation, women with premature menopause now have hoped to mother a child. Hormone replacement therapy is beneficial to adverse consequences of premature menopause. Women with premature menopause are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. Public enlightenment and education is important tool to save those at risk.

    The vaginal microbiota helps protect the female genital tract from disease. We sought to describe the composition of the vaginal microbiota in premenopausal, perimenopausal, and postmenopausal women and to explore the association between the microbiota and vulvovaginal atrophy (VVA). Eighty-seven women (aged 35-60 y) were classified as premenopausal (n = 30), perimenopausal (n = 29), or postmenopausal (n = 28) according to Stages of Reproductive Aging Workshop guidelines. Midvaginal bacterial community composition was characterized by 16S ribosomal RNA gene analysis. Bacterial communities clustered into six community state types (CSTs), of which four were dominated by Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus iners, or Lactobacillus jensenii, and two (CST IV-A and CST IV-B) had low relative abundance of Lactobacillus. CST IV-A was characterized by Streptococcus and Prevotella, whereas CST IV-B was characterized by Atopobium. There were significant associations between menopause stage and CST (P = 0.004) and between VVA and CST (P = 0.002). Perimenopausal women were more likely to be classified as CST IV-A or L. gasseri CST, whereas postmenopausal women were often classified as CST IV-A. CSTs dominated by L. crispatus and L. iners were more prevalent in premenopausal women. Nineteen participants had signs of mild or moderate VVA. Compared with women with no VVA, the vaginal microbiota of women with mild or moderate atrophy had 25-fold greater odds of being classified as CST IV-A versus L. crispatus CST (adjusted odds ratio, 25.89; 95% credible interval, 2.98-406.79). A distinct bacterial community state (CST IV-A) with a low relative abundance of Lactobacillus is associated with VVA. Future studies recruiting a larger number of women are needed to replicate the findings. This study provides an impetus for future longitudinal studies designed to manage, modulate, and restore vaginal microbiota homeostasis, which would provide stronger evidence for

    Full Text Available Osteoprotegerin (OPG and osteocalcin (OC are essential bone proteins. Recent studies have demonstrated that they are not secreted solely by bone cells; they play roles in the vascular function and energy metabolism, and they are influenced by multiple factors. The aim of the current study was to investigate the influence of menopause and age on OPG and OC in women with different thyroid-stimulating hormone (TSH levels. Material and Methods We studied 49 women with elevated TSH, 26 with suppressed TSH, and 67 age-matched euthyroid controls. Of them 64 were menstruating and 78 postmenopausal. Body weight, height, waist circumference (WC, body mass index (BMI, serum TSH, free thyroxin (FT4, OPG, and OC were measured. Results Generally, both OPG and OC were higher in the postmenopausal women than in the menstruating subjects (OPG 3.85 ± 1.49 pmol/L vs. 5.84 ± 2.42 pmol/L, P < 0.001; OC 8.84 ± 3.70 ng/dL vs. 12.87 ± 6.45 ng/dL, P < 0.001, and within the two thyroid dysfunction subgroups and the controls (all P < 0.05. OPG correlated with age (postmenopausal rho = 0.57, P < 0.001; premenopausal rho = 0.31, P = 0.015. Among the premenopausal subjects, OPG was higher in those with low TSH than in the controls ( P = 0.048. OC correlated negatively with BMI and WC in the postmenopausal group (Spearman rho = –-0.25, P = 0.03 and rho = –-0.42, P < 0.001 respectively. OC was higher in the postmenopausal subjects with low TSH than in those with elevated TSH ( P = 0.024, and correlated positively with FT4 (rho = 0.40, P = 0.002 and negatively with TSH (rho = -0.29, P = 0.013. CONCLUSIONS In women, OPG and OC depended differently on age and menopause and, to a lesser extent, on the thyroid function and body composition.

    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

    There is a need for more knowledge about how survivors of childhood cancer perceive their lives and what influence current health status has on their quality of life. The purpose was to describe this among a group of long-term survivors and among a comparison group. Telephone interviews were performed with a cohort of 246 long-term survivors and 296 randomly selected from the general population using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW). The participants nominated the areas they considered to be most important in life and rated the current status of each area on a seven-point category scale. An overall individual index score was calculated as a measure of quality of life. Self-reported health status was assessed using the Short Form Health Survey (SF-36). Long-term survivors rated their overall quality of life and self-reported health status almost in parity with the comparison group. In both groups, family life, relations to other people, work and career, interests and leisure activities were the areas most frequently reported to influence quality of life. The survivors only differed from the comparison group on one of eight SF-36 scales reflecting problems with daily activities owing to physical health. Health status was not shown to have a major impact on overall quality of life, indicating that health and quality of life should be evaluated distinctively as different constructs. This should be taken in consideration in clinical care of children with childhood cancer and long-term survivors. (c) 2010 Wiley-Liss, Inc.

    Background & objectives: The age at which menopause naturally occurs may reflect nutritional and environmental circumstances as well as genetic factors. In this study we examined natural menopause as a marker of women's health at the population level in India and in some major States. Methods: Data from the Indian District Level Household Survey (DLHS) carried out during 2007-2008 covering 643,944 ever-married women aged 15-49 yr were used; women of older ages were not included in this survey. Since not all women in this age group had achieved natural menopause at the time of survey, Cox proportional hazard regression models were employed to obtain the median age of women reporting a natural menopause, excluding those who underwent hysterectomy. Hazard ratios (HRs) were estimated for key socio-economic and reproductive variables that could potentially affect the age at natural menopause menopause prior to age 40 was reported by approximately 1.5 per cent of women. In the national data set, significant associations with age at natural menopause were identified with marriage breakdown or widowhood, poverty, Muslim religious affiliation, ‘scheduled caste’ status, not having received schooling, rural residence, having never used contraceptive pills, not been sterilized or had an abortion, low parity and residence in the western region. Within data from five selected States examined separately, the strength of these associations varied. Interpretation & conclusions: Associations of natural menopause with sociocultural, family planning and demographic variables were noted. Most importantly, there was an association with poverty that would require further investigation as to causality. The proportion of women experiencing early menopause may represent a useful overall indicator of women's health. The data are reassuring with regard to possible late effects of sterilization on ovarian function. PMID:28139535

    Female-to-male ratio in primary hyperparathyroidism (PHPT) is 3:1, but data on sex impact on the clinical presentation are limited. We evaluated, retrospectively, sex difference in biochemistry and clinical presentation at diagnosis in a monocentric series of 417 patients with PHPT: 93 men (58.6 ± 14.5 years), and 324 women (61.7 ± 12.8 years), of whom 54 were premenopausal (pre-F) and 270 postmenopausal (post-F). Men were significantly younger (P = 0.046) and more frequently symptomatic than women (62.3% vs 47%, P = 0.016). No sex difference was found in serum parathyroid hormone, calcium, creatinine, 25-hydroxy-vitamin D, and urinary calcium levels, whereas serum phosphate was higher in women. Nephrolithiasis (detected by imaging or history of passing stones) was more frequent in men (50.5% vs 33% in women, P = 0.003) and osteoporosis (T-score clinical presentation is different, mostly due to menopausal state. However, surgical referral was indicated equally in men and women. Copyright © 2017 Endocrine Society

    Prospective studies on physical activity and diet and the onset of natural menopause are scarce. The aim of this study was to examine the association of physical activity and dietary factors potentially related to endogenous estrogen levels such as fats, dietary fiber, soy isoflavones, and alcohol with the onset of menopause in a cohort of premenopausal women. Study participants were 3,115 premenopausal Japanese women aged 35 to 56 years derived from the participants in the Takayama Study. Physical activity was assessed by a validated questionnaire at baseline, and the metabolic equivalent score was calculated. The dietary intakes were estimated by a validated food frequency questionnaire at baseline and adjusted for total energy. Menopause status was defined as the absence of menstruation for 12 months or more. The Cox proportional hazard model was used to estimate the hazard ratio of the occurrence of menopause after controlling for age, parity, body mass index, smoking status, years of education, and lifelong irregular menstrual cycle. During the 10-year follow-up, 1,790 women experienced natural menopause. A high physical activity level and a high intake of polyunsaturated fat were moderately but significantly associated with the earlier onset of menopause; the hazard ratios for the highest versus lowest quartile were 1.17 (95% CI, 1.02-1.34) for physical activity and 1.15 (95% CI, 1.01-1.31) for polyunsaturated fat intake. Total fat, other types of fat, dietary fiber, soy isoflavones, and alcohol were not associated with the onset of menopause. These data suggest that high levels of physical activity and polyunsaturated fat intake are associated with earlier onset of menopause.

    Full Text Available BACKGROUND: This study aimed to determine the association of lipoprotein-associated phospholipase A(2 (Lp-PLA(2 activity in circulation and peripheral blood mononuclear cells (PBMCs with inflammatory and oxidative stress markers in nonobese women and according to menopausal status. Lp-PLA(2 activity, a marker for cardiovascular risk is associated with inflammation and oxidative stress. METHODOLOGY/PRINCIPAL FINDINGS: Eighty postmenopausal women (53.0±4.05 yr and 96 premenopausal women (39.7±9.25 yr participated in this study. Lp-PLA(2 activities, interleukin (IL-6, tumor necrosis factor (TNF-α, and IL-1β in plasma as well as in PBMCs were measured. Plasma ox-LDL was also measured. Postmenopausal women demonstrated higher circulating levels of ox-LDL and IL-6, as well as IL-6, TNF-α, and IL-1β in PBMCs, than premenopausal women. In both groups, plasma Lp-PLA(2 activity positively correlated with Lp-PLA(2 activity in PBMCs and plasma ox-LDL. In premenopausal women, Lp-PLA(2 activities in plasma and PBMCs positively correlated with IL-6, TNF-α, and IL-1β in PBMCs. In postmenopausal women, plasma ox-LDL positively correlated with PBMC cytokine production. In subgroup analysis of postmenopausal women according to plasma ox-LDL level (median level: 48.715 U/L, a significant increase in Lp-PLA(2 activity in the plasma but not the PBMCs was found in the high ox-LDL subgroup. Plasma Lp-PLA(2 activity positively correlated with unstimulated PBMC Lp-PLA(2 activity in the low ox-LDL subgroup (r = 0.627, P<0.001, whereas in the high ox-LDL circulating Lp-PLA(2 activity positively correlated with plasma ox-LDL (r = 0.390, P = 0.014 but not with Lp-PLA(2 activity in PBMCs. CONCLUSIONS/SIGNIFICANCE: The lack of relation between circulating Lp-PLA(2 activity and Lp-PLA(2 activity in PBMCs was found in postmenopausal women with high ox-LDL. This may indicate other sources of circulating Lp-PLA(2 activity except PBMC in postmenopausal women

    Aging intersects with reproductive senescence in women by promoting a systemic low-grade chronic inflammation that predisposes women to several diseases including ovarian cancer (OC). OC risk at menopause is significantly modified by parity records during prior fertile life. To date, the combined effects of age and parity on the systemic inflammation markers that are particularly relevant to OC initiation and progression at menopause remain largely unknown. Herein, we profiled a panel of circulating cytokines in multiparous versus virgin C57BL/6 female mice at peri-estropausal age and investigated how cytokine levels were modulated by intraperitoneal tumor induction in a syngeneic immunocompetent OC mouse model. Serum FSH, LH and TSH levels increased with age in both groups while prolactin (PRL) was lower in multiparous respect to virgin mice, a finding previously observed in parous women. Serum CCL2, IL-10, IL-5, IL-4, TNF-α, IL1-β and IL-12p70 levels increased with age irrespective of parity status, but were specifically reduced following OC tumor induction only in multiparous mice. Animals developed hemorrhagic ascites and tumor implants in the omental fat band and other intraperitoneal organs by 12 weeks after induction, with multiparous mice showing a significantly extended survival. We conclude that previous parity history counteracts aging-associated systemic inflammation possibly by reducing the immunosuppression that typically allows tumor spread. Results suggest a partial impairment of the M2 shift in tumor-associated macrophages as well as decreased stimulation of regulatory B-cells in aged mice. This long term, tumor-concurrent effect of parity on inflammation markers at menopause would be a contributing factor leading to decreased OC risk.

    Full Text Available The knowledge regarding the intestinal microbial types involved in isoflavone bioavailabililty and metabolism is still limited. The present work reports the influence of a treatment with isoflavones for six months on the faecal bacterial communities of 16 menopausal women, as determined by culturing and culture-independent microbial techniques. Changes in faecal communities were analysed with respect to the womenʼs equol-producing phenotype. Compared to baseline, at 1 and 3 months the counts for all microbial populations in the faeces of equol-producing women had increased strongly. In contrast, among the non-producers, the counts for all microbial populations at 1 month were similar to those at baseline, and decreased significantly by 3 and 6 months. Following isoflavone intake, major bands in the denaturing gradient gel electrophoresis (DGGE profiles appeared and disappeared, suggesting important changes in majority populations. In some women, increases were seen in the intensity of specific DGGE bands corresponding to microorganisms known to be involved in the metabolism of dietary phytoestrogens (Lactonifactor longoviformis, Faecalibacterium prausnitzii, Bifidobacterium spp., Ruminococcus spp.. Real-Time quantitative PCR revealed that the Clostridium leptum and Clostridium coccoides populations increased in equol producers, while those of bifidobacteria and enterobacteria decreased, and vice versa in the non-producers. Finally, the Atopobium population increased in both groups, but especially in the non-producers at three months. As the main findings of this study, (i variations in the microbial communities over the six-month period of isoflavone supplementation were large; (ii no changes in the faecal microbial populations that were convincingly treatment-specific were seen; and (iii the production of equol did not appear to be associated with the presence of, or increase in the population of, any of the majority bacterial types analysed.

    It has long been held that parity reduces risk of breast cancer. However, accumulating evidence indicates that the effects of parity, as well as breastfeeding, may vary according to estrogen receptor (ER) status. We evaluated these associations in a case-control study among African-American women in New York City and New Jersey. In the Women's Circle of Health Study, including 786 African-American women with breast cancer and 1,015 controls, data on reproductive histories were collected from in-person interviews, with tumor characteristics abstracted from pathology reports. We calculated number of live births and months breastfeeding for each child, and examined each in relation to breast cancer by ER status, and for triple-negative (TN) breast cancer. Although associations were not statistically significant, having children was associated with reduced risk of ER+ breast cancer [odds ratio (OR) 0.82, 95 % confidence interval (CI) 0.58-1.16], but increased risk of ER- tumors, with associations most pronounced for TN breast cancer (OR 1.81, 95 % CI 0.93-3.51). Breastfeeding gave no additional benefit for ER+ cancer, but reduced the risk of ER- disease associated with parity. Accumulating data from a number of studies, as well as our own in African-American women, indicate that the effects of parity and breastfeeding differ by ER status. African-American women are more likely to have children and not to breastfeed, and to have ER- and TN breast cancer. It is possible that breastfeeding in this population could reduce risk of more aggressive breast cancers.

    Obesity and breast cancer risk is multifaceted and genes associated with energy homeostasis may modify this relationship. We evaluated 10 genes that have been associated with obesity and energy homeostasis to determine their association with breast cancer risk in Hispanic/Native American (2111 cases, 2597 controls) and non-Hispanic white (1481 cases, 1585 controls) women. Cholecystokinin (CCK) rs747455 and proopiomelanocortin (POMC) rs6713532 and rs7565877 (for low Indigenous American (IA) ancestry); CCK rs8192472 and neuropeptide Y (NYP) rs16141 and rs14129 (intermediate IA ancestry); and leptin receptor (LEPR) rs11585329 (high IA ancestry) were strongly associated with multiple indicators of body size. There were no significant associations with breast cancer risk between genes and SNPs overall. However, LEPR was significantly associated with breast cancer risk among women with low IA ancestry (PARTP=0.024); POMC was significantly associated with breast cancer risk among women with intermediate (PARTP=0.015) and high (PARTP=0.012) IA ancestry. The overall pathway was statistically significant for pre-menopausal women with low IA ancestry (PARTP=0.05), as was cocaine and amphetamine regulated transcript protein (CARTPT) (PARTP=0.014) and ghrelin (GHRL) (PARTP=0.007). POMC was significantly associated with breast cancer risk among post-menopausal women with higher IA ancestry (PARTP=0.005). Three SNPs in LEPR (rs6704167, rs17412175, and rs7626141), and adiponectin (ADIPOQ); rs822391) showed significant 4-way interactions (GxExMenopausexAncestry) for multiple indicators of body size among pre-menopausal women. Energy homeostasis genes were associated with breast cancer risk; menopausal status, body size, and genetic ancestry influenced this relationship. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Background Previous screening trials for early detection of ovarian cancer in postmenopausal women have used the standard CA125 cut-point of 35 U/mL, the 98th percentile in this population yielding a 2% false positive rate, while the same cut-point in trials of premenopausal women results in substantially higher false positive rates. We investigated demographic and clinical factors predicting CA125 distributions, including 98th percentiles, in a large population of high-risk women participating in two ovarian cancer screening studies with common eligibility criteria and screening protocols. Methods Baseline CA125 values and clinical and demographic data from 3,692 women participating in screening studies conducted by the NCI-sponsored Cancer Genetics Network and Gynecologic Oncology Group were combined for this pre-planned analysis. Due to the large effect of menopausal status on CA125 levels, statistical analyses were conducted separately in pre- and postmenopausal subjects to determine the impact of other baseline factors on predicted CA125 cut-points based on the 98th percentile. Results The primary clinical factor affecting CA125 cut-points was menopausal status, with premenopausal women having a significantly higher cut-point of 50 U/mL while in postmenopausal subjects the standard cut-point of 35 U/mL was recapitulated. In premenopausal women, current oral contraceptive (OC) users had a cut-point of 40 U/mL. Conclusions To achieve a 2% false positive rate in ovarian cancer screening trials and in high-risk women choosing to be screened, the cut-point for initial CA125 testing should be personalized primarily for menopausal status (~ 50 for premenopausal women, 40 for premenopausal on OC, 35 for postmenopausal women).

    The field of parity mixing in light nuclei bears upon one of the exciting and active problems of physics--the nature of the fundamental weak interaction. It is also a subject where polarization techniques play a very important role. Weak interaction theory is first reviewed to motivate the parity mixing experiments. Two very attractive systems are discussed where the nuclear physics is so beautifully simple that the experimental observation of tiny effects directly measures parity violating (PV) nuclear matrix elements which are quite sensitive to the form of the basic weak interaction. Since the measurement of very small analyzing powers and polarizations may be of general interest to this conference, some discussion is devoted to experimental techniques

A cross-sectional study was conducted on a sample of 331 postmenopausal women-264 (80%) domicile women and 67 (20%) refugee women-between June 2009 and February 2011. The study encompassed 331 women with a mean age of 57.0 years (range, 39-75 y). The overall mean age at menopause was 49.1 years. The mean age at menopause was higher in domicile women (49.3 y) than in refugee women (48.0 y; unpaired t test, P = 0.023). After adjustment for age at menarche, education, marital status, living place, body mass index, number of abortions, use of contraceptives, and current smoking, only refugee status and parity remained as significant independent predictors of age at menopause (score test, P = 0.025). Refugee women had an increased probability of earlier onset of menopause compared with nonrefugee women (adjusted hazard ratio, 1.33; 95% CI, 1.02-1.75; P = 0.039), whereas there was a decreased probability of experiencing menopause with increasing number of births (adjusted hazard ratio, 0.92; 95% CI, 0.84-0.996; P = 0.04). The age at onset of menopause in refugee women is lower than that in domicile women, indicating that war, independently of other factors, could influence the age when menopause occurs. On average, women who lived in Bosnia and Herzegovina during the war and postwar period entered menopause earlier than did women from Europe.

    To investigate effects of menopausal status, oral contraceptives (OC), and postmenopausal hormone therapy (HT) on normal breast parenchymal contrast enhancement (CE) and non-mass-like enhancing areas in magnetic resonance mammography (MRM). A total of 459 female volunteers (mean age 49.1 ± 12.5 years) underwent T1-weighted 3D MRM 1-5 min after bolus injection of gadobutrol. Quantitative analysis was performed in normal breast parenchyma by manually tracing regions of interest and calculating percentage CE. Semiquantitative analysis was performed in non-mass-like enhancing areas, and signal intensity changes were characterised by five predefined kinetic curve types. The influence of OC (n = 69) and HT (n = 24) on CE was studied using random effects models. Breast parenchymal enhancement was significantly higher in premenopausal than in postmenopausal women (P < 0.001). CE decreased significantly with the use of OC (P = 0.01), while HT had negligible effects (P = 0.52). Prevalence of kinetic curve types of non-mass-like enhancement differed strongly between pre- and postmenopausal women (P < 0.0001), but was similar in OC users and non-OC users (P = 0.61) as well as HT users and non-HT users (P = 0.77). Normal breast parenchymal enhancement and non-mass-like enhancing areas were strongly affected by menopausal status, while they were not affected by HT use and only moderately by OC use. (orig.)

    We examined the associations of mammographic breast density with breast cancer risk by tumor aggressiveness and by menopausal status and current postmenopausal hormone therapy. This study included 2596 invasive breast cancer cases and 4059 controls selected from participants of four nested case-control studies within four established cohorts: the Mayo Mammography Health Study, the Nurses' Health Study, Nurses' Health Study II, and San Francisco Mammography Registry. Percent breast density (PD), absolute dense (DA), and non-dense areas (NDA) were assessed from digitized film-screen mammograms using a computer-assisted threshold technique and standardized across studies. We used polytomous logistic regression to quantify the associations of breast density with breast cancer risk by tumor aggressiveness (defined as presence of at least two of the following tumor characteristics: size ≥2 cm, grade 2/3, ER-negative status, or positive nodes), stratified by menopausal status and current hormone therapy. Overall, the positive association of PD and borderline inverse association of NDA with breast cancer risk was stronger in aggressive vs. non-aggressive tumors (≥51 vs. 11-25% OR 2.50, 95% CI 1.94-3.22 vs. OR 2.03, 95% CI 1.70-2.43, p-heterogeneity = 0.03; NDA 4th vs. 2nd quartile OR 0.54, 95% CI 0.41-0.70 vs. OR 0.71, 95% CI 0.59-0.85, p-heterogeneity = 0.07). However, there were no differences in the association of DA with breast cancer by aggressive status. In the stratified analysis, there was also evidence of a stronger association of PD and NDA with aggressive tumors among postmenopausal women and, in particular, current estrogen+progesterone users (≥51 vs. 11-25% OR 3.24, 95% CI 1.75-6.00 vs. OR 1.93, 95% CI 1.25-2.98, p-heterogeneity = 0.01; NDA 4th vs. 2nd quartile OR 0.43, 95% CI 0.21-0.85 vs. OR 0.56, 95% CI 0.35-0.89, p-heterogeneity = 0.01), even though the interaction was not significant. Our findings suggest that associations of mammographic

    Conclusions: Menopausal transition brings about anomalies in total body composition characterized by an increased body fat mass and central adiposity. This creates a compatible atmosphere for abnormal metabolism and aggravated cardio metabolic risk factors. Thus, menopausal status and associated obesity is the major predictor of metabolic aberrations over age in menopausal women.

    Full Text Available Abstract Background The metabolic syndrome is defined as an assemblage of risk factors for cardiovascular diseases, and menopause is associated with an increase in metabolic syndrome prevalence. The aim of this study was to assess the prevalence of metabolic syndrome and its components among postmenopausal women in Tehran, Iran. Methods In this cross-sectional study in menopause clinic in Tehran, 118 postmenopausal women were investigated. We used the adult treatment panel 3 (ATP3 criteria to classify subjects as having metabolic syndrome. Results Total prevalence of metabolic syndrome among our subjects was 30.1%. Waist circumference, HDL-cholesterol, fasting blood glucose, diastolic blood pressure ,Systolic blood pressure, and triglyceride were significantly higher among women with metabolic syndrome (P-value Conclusions Our study shows that postmenopausal status is associated with an increased risk of metabolic syndrome. Therefore, to prevent cardiovascular disease there is a need to evaluate metabolic syndrome and its components from the time of the menopause.

    The purpose of this study was to investigate prospectively whether the apparent diffusion coefficients (ADCs) of both breast cancer and normal fibroglandular tissue vary with the menstrual cycle and menopausal status. Institutional review board approval was obtained, and informed consent was obtained from each participant. Fifty-seven women (29 premenopausal, 28 postmenopausal) with newly diagnosed breast cancer underwent diffusion-weighted imaging twice (interval 12-20 days) before surgery. Two radiologists independently measured ADC of breast cancer and normal contralateral breast tissue, and we quantified the differences according to the phases of menstrual cycle and menopausal status. With normal fibroglandular tissue, ADC was significantly lower in postmenopausal than in premenopausal women (P = 0.035). In premenopausal women, ADC did not differ significantly between proliferative and secretory phases in either breast cancer or normal fibroglandular tissue (P = 0.969 and P = 0.519, respectively). In postmenopausal women, no significant differences were found between ADCs measured at different time intervals in either breast cancer or normal fibroglandular tissue (P = 0.948 and P = 0.961, respectively). The within-subject variability of the ADC measurements was quantified using the coefficient of variation (CV) and was small: the mean CVs of tumor ADC were 2.90 % (premenopausal) and 3.43 % (postmenopausal), and those of fibroglandular tissue ADC were 4.37 % (premenopausal) and 2.55 % (postmenopausal). Both intra- and interobserver agreements were excellent for ADC measurements, with intraclass correlation coefficients in the range of 0.834-0.974. In conclusion, the measured ADCs of breast cancer and normal fibroglandular tissue were not affected significantly by menstrual cycle, and the measurements were highly reproducible both within and between observers.

  14. Environment, human reproduction, menopause, and andropause.

    As the hypothalamic gonadotropin-releasing hormone (GnRH) pulse generator is an integrator of hormonal, metabolic, and neural signals, it is not surprising that the function of the hypothalamogonadal axis is subject to the influence of a large array of environmental factors. Before puberty, the central nervous system (CNS) restrains the GnRH pulse generator. Undernutrition, low socioeconomic status, stress, and emotional deprivation, all delay puberty. During reproductive life, among peripheral factors that effect the reproductive system, stress plays an important role. Stress, via the release of corticotropin-releasing factor (CRF), eventually triggered by interleukin 1, inhibits GnRH release, resulting in hypogonadism. Effects of CRF are probably mediated by the opioid system. Food restriction and underweight (anorexia nervosa), obesity, smoking, and alcohol all have negative effects on the GnRH pulse generator and gonadal function. Age and diet are important determinants of fertility in both men and women. The age-associated decrease in fertility in women has as a major determinant chromosomal abnormalities of the oocyte, with uterine factors playing a subsidiary role. Age at menopause, determined by ovarian oocyte depletion, is influenced by occupation, age at menarche, parity, age at last pregnancy, altitude, smoking, and use of oral contraceptives. Smoking, however, appears to be the major determinant. Premature menopause is most frequently attributable to mosaicism for Turner Syndrome, mumps ovaritis, and, above all, total hysterectomy, which has a prevalence of about 12-15% in women 50 years old. Premature ovarian failure with presence of immature follicles is most frequently caused by autoimmune diseases or is the consequence of irradiation or chemotherapy with alkylating cytostatics. Plasma estrogens have a physiological role in the prevention of osteoporosis. Obese women have osteoporosis less frequently than women who are not overweight. Early menopause

    Hormonal changes during menopausal transition are linked to physical and psychological symptoms' emergence. This study aims to explore if life events predict menopausal symptoms. This cross-sectional research encompasses a community sample of 992 women who answered to socio-demographic, health, menopause-related and lifestyle questionnaires; menopausal symptoms and life events were assessed with validated instruments. Structural equation modeling was used to build a causal model. Menopausal status predicted only three symptoms: skin/facial hair changes (β=.136; p=.020), sexual (β=.157; p=.004) and, marginally, vasomotor symptoms (β=.094; p=.054). Life events predicted depressive mood (β=-.391; p=.002), anxiety (β=-.271; p=.003), perceived cognitive impairment (β=-.295; p=.003), body shape changes (β=-.136; p=.031), aches/pain (β=-.212; p=.007), skin/facial hair changes (β=-.171; p=.021), numbness (β=-.169; p=.015), perceived loss of control (β=-.234; p=.008), mouth, nails and hair changes (β=-.290; p=.004), vasomotor (β=-.113; p=.044) and sexual symptoms (β=-.208; p=.009). Although women in peri- and post-menopausal manifested higher symptoms' severity than their pre-menopausal counterparts, only three of the menopausal symptoms assessed were predicted by menopausal status. Since the vast majority of menopausal symptoms' severity was significantly influenced by the way women perceived their recent life events, it is concluded that the symptomatology exacerbation, in peri- and post-menopausal women, might be due to life conditions and events, rather than hormonal changes (nonetheless, the inverse influence should be investigated in future studies). Therefore, these should be accounted for in menopause-related clinical and research settings. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Menopause marks a time of dramatic hormonal and often social change for women. Both risk factors and health needs are likely to change as women pass through menopause. This paper examines the demographic characteristics of the world population of menopausal and post-menopausal women, and also examines the implication of menopause for mortality risks. The numbers of women involved are large. Using age 50 as a proxy for menopause, about 25 million women pass through menopause each year, and we estimate that in 1990 there were 467 million post-menopausal women in the world, with an average age of about 60 years. By 2030, the world population of menopausal and postmenopausal women is projected to increase to 1.2 billion, with 47 million new entrants each year. The mortality implications of menopause are also substantial. Ratios of female to male mortality risks from all causes and from all major cause groups except neoplasms decline to low levels around menopause or shortly thereafter, and then rise again to near unity. This pattern is taken as evidence that the female reproductive period is broadly protective of health, but that this protection disappears after menopause. The main protective effect is through reduced risk of cardiovascular disease mortality, partially offset by increased risks of cancer mortality, particularly of the breast and endometrium.

    Full Text Available AbstractMenopause is a natural phase experienced by every woman, a reproduction process characterized by the end of the fertile period of a woman because the ovaries are no longer produce estrogen and progesterone, and may cause menopausal complaints which are referred to as menopausal syndrome. Problems or changes experienced by menopause women may lead to a crisis that will affect the quality of life. This study aims to analyze the correlation between menopausal syndrome and the quality of life. The study method was analytic observational with cross sectional design. The population were women who had experienced menopause for 1-2 years in Sukahaji Majalengka Primary Health Center area and met the study criteria such as were still have a husband, had no menstruation experience for 1-2 years and were able to read. Sampling technique was performed by total sampling, conducted in February until March 2013. Menopausal syndrome was measured by using MSQ (Menopause Symptom Questionnaire and quality of life was measured by using The World Health Organization Quality Of Life questionnaire (WHOQOL - BREF. Data was analyzed with univariate, bivariate and multivariate statistical analysis. The results presented strong negative correlation between physiological and psychological menopausal syndrome aspects in quality of life (r = -0.786, p = 0.000 and r = -0.706, p = 0.000, a negative correlation was simultaneouly strong in physiological and psychological aspects of menopausal syndrome and the quality of life of women (r = -0.772, p = 0.000, a significant correlation between income and education and quality of life (r = -0.313 p = 0.011 and r = -0.359 p = 0.003.

    Menopause occurs naturally in women at about 50 years of age. There is a wealth of data concerning the relationship of menopause to systemic lupus erythematosus, rheumatoid arthritis, and osteoarthritis; there are limited data concerning other rheumatic diseases. Age at menopause may affect the risk and course of rheumatic diseases. Osteoporosis, an integral part of inflammatory rheumatic diseases, is made worse by menopause. Hormone replacement therapy has been studied; its effects vary depending on the disease and even different manifestations within the same disease. Cyclophosphamide can induce early menopause, but there is underlying decreased ovarian reserve in rheumatic diseases. Published by Elsevier Inc.

    Full Text Available Menopause is a process in the climacteric period, characterized by a reduction in ovarian activity, a fall in the fertility rate, and a range of symptoms including irregular menstruation intervals. Most women enter menopause in their 40s, but this can vary from one individual to another. Although there are many factors affecting the age of menopause onset, there is no general agreement on them. Studies have shown many factors to affect the age of menopause, such as the mother’s age at menopause, the age at menarche, gestational age, use of oral contraceptives, irregular menstrual cycle, number of pregnancies, body mass index, use of tobacco and alcohol, physical activity, unilateral oophorectomy, serum lead levels, consumption of polyunsaturated fat, socioeconomic status and educational level. During this period, hormonal and biochemical changes give rise to various symptoms in the woman’s body. In menopause period, physical, psychological, social and sexual changes have a negative effect on quality of life in women. Recently, different measures have been used to assess women’s quality of life in this period of change. The purpose of this review was to examine the factors affecting the onset age of menopause and the measures of quality of life related to menopause.

    To establish the reproducibility of apparent diffusion coefficient (ADC) measurements in normal fibroglandular breast tissue and to assess variation in ADC values with phase of the menstrual cycle and menopausal status. Thirty-one volunteers (13 premenopausal, 18 postmenopausal) underwent magnetic resonance twice (interval 11-22 days) using diffusion-weighted MRI. ADC total and a perfusion-insensitive ADC high (omitting b = 0) were calculated. Reproducibility and inter-observer variability of mean ADC values were assessed. The difference in mean ADC values between the two phases of the menstrual cycle and the postmenopausal breast were evaluated. ADC total and ADC high showed good reproducibility (r% = 17.6, 22.4). ADC high showed very good inter-observer agreement (kappa = 0.83). The intraclass correlation coefficients (ICC) were 0.93 and 0.91. Mean ADC values were significantly lower in the postmenopausal breast (ADC total 1.46 ± 0.3 x 10 -3 mm 2 /s, ADC high 1.33 ± 0.3 x 10 -3 mm 2 /s) compared with the premenopausal breast (ADC total 1.84 ± 0.26 x 10 -3 mm 2 /s, ADC high 1.77 ± 0.26 x 10 -3 mm 2 /s; both P total P = 0.2, ADC high P = 0.24) or between postmenopausal women taking or not taking oestrogen supplements (ADC total P = 0.6, ADC high P = 0.46). ADC values in fibroglandular breast tissue are reproducible. Lower ADC values within the postmenopausal breast may reduce diffusion-weighted contrast and have implications for accurately detecting tumours. (orig.)

BMD at the femoral neck (FN) and lumbar spine (LS) was measured by dual energy X-ray absorptiometry (DXA) method. Diagnosis of osteoporosis (OP) was confirmed by World Health Organization criteria. Women were stratified according to number of parity as 7 parity groups as well as in age groups of or = 65 years. BMD values and frequency of OP were compared across the groups according to age. Multiple logistic regression analysis with calculation of adjusted odds ratio (OR) was used for association. A total of 264 women with mean age of 63 +/- 8.7 and mean menopausal duration of 15.8 +/- 10.2 years were studied. LS-OP and FN-OP were observed in 28% and 58.3% of women, respectively. There were significant differences in BMD values across different parity groups at both sites of LS and FN (p = 0.011 and p = 0.036, respectively). Parity 4-7 (vs. 7 significantly decreased LS-BMD and FN-BMD as compared with 0-7 parity (p = 0.006 and p = 0.009, respectively). Parity > 7 increased the risk of LS-OP by OR = 1.81 (95% CI 1.03-3.1, p = 0.037) and FN-OP by OR = 1.67 (95% CI 0.97-2.8, p = 0.063). In addition, women with high parity had lower BMD decline at LS and FN by age (> or = 65 vs. 7 is associated with spinal trabecular bone loss in younger postmenopausal women as well as an osteoprotective effect against age-related bone loss, which counteracts the early negative effect. Therefore, parity should not be considered as a risk factor for postmenopausal osteoporosis.

    Full Text Available The digest has been prepared to review available clinical evidence on herbs used in treatment of menopause symptoms. Effectiveness of Humulus lupulus, Vitex agnus-castus, Dioskorea vilosa, Linum usitatissimum, Pinus pinaster, cruciferous vegetables, Cimicifuga racemosa L., Angelica sinensis, Oenothera biennis L., Hypericum perforatum L., Panax ginseng, Ginkgo biloba, Glycine soja, Trifolium pratense and Piper methysticum herbs were assessed for treatment of menopausal symptoms in the studies. Herbs used as alternative supplementary treatment for menopause symptoms have been found to have a limited effect. Thus more studies are warranted to assess effectiveness of herbal treatments for menopausal symptoms. [Archives Medical Review Journal 2015; 24(4.000: 520-530

    Full Text Available Metabolic disorders occurring in menopause, including dyslipidemia, disorders of carbohydrate metabolism (impaired glucose tolerance – IGT, type 2 diabetes mellitus – T2DM or components of metabolic syndrome, constitute risk factors for cardiovascular disease in women. A key role could be played here by hyperinsulinemia, insulin resistance and visceral obesity, all contributing to dyslipidemia, oxidative stress, inflammation, alter coagulation and atherosclerosis observed during the menopausal period. Undiagnosed and untreated, metabolic disorders may adversely affect the length and quality of women’s life. Prevention and treatment preceded by early diagnosis should be the main goal for the physicians involved in menopausal care. This article represents a short review of the current knowledge concerning metabolic disorders (e.g. obesity, polycystic ovary syndrome or thyroid diseases in menopause, including the role of a tailored menopausal hormone therapy (HT. According to current data, HT is not recommend as a preventive strategy for metabolic disorders in menopause. Nevertheless, as part of a comprehensive strategy to prevent chronic diseases after menopause, menopausal hormone therapy, particularly estrogen therapy may be considered (after balancing benefits/risks and excluding women with absolute contraindications to this therapy. Life-style modifications, with moderate physical activity and healthy diet at the forefront, should be still the first choice recommendation for all patients with menopausal metabolic abnormalities.

    Objective: To determine the knowledge and attitude towards menopause among postmenopausal women seeking gynecological treatment. Results: The mean age of respondents was 54.4 years. Fifty-two (74.3%) women knew about menopause, 39 (55.7%) were aware of symptomatology while only 7(10%) knew sequelae of menopause. Fifty-three (75.5%) women were satisfied with cessation of menstruation and only 17 (24.3%) desired to continue menstruation. Twenty-four (34.3%) respondents were unhappy with their menopausal status. Thirty-two (45.7%) women were content with their present sexual relations, 18 (25.7%) were dissatisfied and 20 (28.6%) had no sexual activity. Fifty-two (74.3%) women felt a need for health education on menopause in educational institutions. Thirty-three (47.1%) considered treatment of menopause necessary. Four (5.7%) were aware of any treatment of menopause and 55 (78.6%) desired to learn more about menopause. Conclusion: Women have different views about menopause, few see it as a medical condition requiring treatment, whereas majority consider it is a natural transition. There was breath of knowledge regarding significance of menopause. (author)

    Menopause may be a time of increased mood symptoms for some women. This systematic review aimed to examine the severity of symptoms and prevalence of mood changes in women with bipolar disorder during peri-menopause and post-menopause. A systematic review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The two primary outcomes assessed were relapse rates and symptom severity during menopause. Databases searched were MEDLINE, EMBASE, PsychInfo, CINAHL and SCOPUS from January 1980 until December 2016. Nine studies, including a total of 273 participants diagnosed with bipolar disorder and who reported menopause, were included in the narrative synthesis. Menopause was reported to be associated with increased symptoms overall, and with depression in particular (range of 46%-91%). The collection of self-reported retrospective data was the most commonly used method to record menopause status. The impact of menopause on illness course for women with bipolar disorder is largely under-explored. Preliminary evidence suggests that it may be associated with increased bipolar symptoms. Further work is needed to explore how menopause may interact with bipolar disorder over time and the nature of these symptom changes, and if and how menopause may differ from other reproductive stages. © 2017 John Wiley & Sons A/S.

    Objective Early age at menopause is associated with increased risk of cardiovascular disease, stroke, osteoporosis and all-cause mortality. Cigarette smoke exposure in adulthood is an established risk factor for earlier age at natural menopause and may be related to age at menopausal transition. Using data from two U.S. birth cohorts, we examined the association between smoke exposure at various stages of the life course (prenatal, childhood exposure to parental smoking and adult smoke exposure) with menopause status in 1,001 women aged 39 – 49 years at follow-up. Methods We used logistic regression analysis, adjusting for age at follow-up, to estimate odds ratios (ORs) and 95% confidence intervals (CI) relating smoke exposure to natural menopause and menopausal transition. Results The magnitudes of the associations for natural menopause were similar, but not statistically significant after adjustment for confounders for i) women with prenatal smoke exposure who did not smoke at adult follow-up (OR= 2.7 [95% CI 0.8, 9.4]) and ii) current adult smokers who were not exposed prenatally (OR= 2.8 [95% CI 0.9, 9.0]). Women who had been exposed to prenatal smoke and were current smokers had three times the risk of experiencing natural menopause (adjusted OR=3.4 [95% CI 1.1, 10.3]) compared to women without smoke exposure in either time period. Only current smoking of long duration (>26 years) was associated with the timing of the menopausal transition. Conclusion Our data suggest that exposure to smoke both prenatally and around the time of menopause accelerates ovarian aging. PMID:25803667

    Early age at menopause is associated with increased risk of cardiovascular disease, stroke, osteoporosis, and all-cause mortality. Cigarette smoke exposure in adulthood is an established risk factor for earlier age at natural menopause and may be related to age at the menopausal transition. Using data from two US birth cohorts, we examined the association between smoke exposure at various stages of the life course (prenatal exposure, childhood exposure to parental smoking, and adult smoke exposure) and menopause status in 1,001 women aged 39 to 49 years at follow-up. We used logistic regression analysis (adjusting for age at follow-up) to estimate odds ratios (ORs) and 95% confidence intervals (CI) relating smoke exposure to natural menopause and the menopausal transition. The magnitudes of the associations for natural menopause were similar but not statistically significant after adjustment for confounders among (i) women with prenatal smoke exposure who did not smoke on adult follow-up (OR, 2.7; 95% CI, 0.8-9.4) and (ii) current adult smokers who were not exposed prenatally (OR, 2.8; 95% CI, 0.9-9.0). Women who had been exposed to prenatal smoke and were current smokers had three times the risk of experiencing earlier natural menopause (adjusted OR, 3.4; 95% CI, 1.1-10.3) compared with women without smoke exposure in either period. Only current smoking of long duration (>26 y) was associated with the timing of the menopausal transition. Our data suggest that exposure to smoke both prenatally and around the time of menopause accelerates ovarian aging.

  18. Do BRCA1/2 mutation carriers have an earlier onset of natural menopause?

    It has been hypothesized that BRCA1/2 mutation carriers have an earlier age at natural menopause (ANM), although to date findings are inconclusive. This study assessed the influence of BRCA mutation status on ANM, and aimed to explore the reasons of inconsistency in the literature. Cross-sectional assessment from an ongoing nationwide cohort study among members of BRCA1/2 mutated families. Information was obtained by a standardized questionnaire. Kaplan-Meier curves were constructed, and Cox regression was used to assess the association between BRCA1/2 mutation status and ANM. Adjustments were made for birth cohort, family, smoking, use of hormonal contraceptives, and parity. A total of 1,208 BRCA1/2 mutation carriers and 2,211 proven noncarriers were included. Overall, no association was found between BRCA1/2 mutation status and ANM (adjusted hazard ratio [HR] = 1.06 [95% CI, 0.87-1.30]). We examined if the null finding was due to informative censoring by uptake of risk-reducing salpingo-oophorectomy. Indeed, within the oldest birth cohort, in which the percentage of surgical menopause events was lowest and comparable between carriers and noncarriers, the HR for earlier natural menopause in carriers was 1.45 (95% CI, 1.09-1.94). The second oldest birth cohort, however, demonstrated a decreased HR (0.67 [95% CI, 0.46-0.98]), and thus no trend over birth cohorts was found. Various types of selection bias hamper the comparison of ANM between BRCA1/2 mutation carriers and noncarriers, genetically tested in the clinic.

    The aim of the present study was to assess whether menopausal status influences the occurrence of nocturnal awakening with headache (NAH) in the female population of Sao Paulo, Brazil. We also examined the relationship of this complaint to sociodemographic determinants, hot flushes, sleep quality and parameters, anxiety and depressive symptoms, somnolence and fatigue according to menopausal status. The female population of the Sao Paulo Epidemiologic Sleep Study (EPISONO) (n = 576) was divided according to menopausal status (pre-, peri-, early and late menopause) based on questionnaires and hormonal blood measures. The complaint of waking up because of a headache at least once a week was assessed by the UNIFESP Sleep questionnaire. Additionally, hot flushes, sleep complaints, anxiety and depressive symptoms, somnolence and fatigue were assessed by specific questionnaires. A full-night polysomnography assessed sleep parameters. The prevalence of NAH in women in the Sao Paulo population was 13.3%. Perimenopause was associated with a higher risk of having NAH (odds ratio 13.9; 95% confidence interval 4.3-45.2). More complaints of NAH were observed in obese women. All the groups with NAH showed more hot flushes, worse subjective sleep quality, more complaints of insomnia, anxiety symptoms and fatigue. We observed a constellation of symptoms in women according to menopausal status and NAH that included hot flushes, sleep complaints, more anxiety symptoms and fatigue. Moreover, some of these symptoms were more frequent in perimenopausal women with NAH. Therefore, we concluded that menopausal status influences NAH and the women in perimenopause presented a high risk of having this complaint.

    A lifespan approach was used to evaluate age at menopause, and determinants of surgical and natural menopause, in the multi-ethnic community of Hilo, Hawaii. Participants aged 40-60 years (n=898) were drawn from a larger, randomly generated sample recruited by postal questionnaires. Median age at natural menopause was computed by probit analysis. Logistic regression analysis was applied to examine determinants of hysterectomy, and Cox regression analysis was used to examine risk factors for an earlier age at menopause. History of hysterectomy, age at menopause. Frequency of hysterectomy was 19.2% at a mean age of 40.5 years. The likelihood of hysterectomy increased with older ages, lower education, mixed ancestry, having been overweight at age 30, and married 20 years prior to survey. Median age at natural menopause was 53.0 years. Smoking and not being married 10 years before survey were associated with an earlier age at menopause. Median age at menopause was later than the national average. Ethnicity and education were determinants of hysterectomy, but not associated with age at natural menopause. Events later in the lifespan (e.g., smoking and not being married 10 years prior to the survey) were more important than earlier events (e.g., childhood residence) in relation to age at menopause. The timing of weight gain and marital status appear to be important in relation to surgical menopause, and the timing of marital status appears to be important in relation to the timing of natural menopause.

    Full Text Available Menopause, especially the symptoms and complications, is always an interesting topic to be discussed. It is actually a normal part of woman's life entering ages of 50. The symptoms of menopause are highly individual to each woman. Some may experience multiple physical and psychological symptoms that may continue to social impacts. Misinterpretation as other disease symptoms could happen and lead to incorrect treatment. Many studies have been done to learn more about the menopause physiological process, symptoms, complication, and treatment. So many preventive and treatment options are offered, including hormone therapy and practicing healthy life style. By understanding the menopause, it is expected that symptoms could be controlled and complications could be avoided.   Key words : Woman, Menstrual Period, Menopause, Healthy

    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

    2017-05-01

    The aim of this review is to examine three questions: What are the risks and benefits of treating women with schizophrenia with hormone therapy (HT) at menopause? Should the antipsychotic regimen be changed at menopause? Do early- and late-onset women with schizophrenia respond differently to HT at menopause? MEDLINE databases for the years 1990 to 2016 were searched using the following interactive terms: schizophrenia, gender, menopause, estrogen, and hormones. The selected articles (62 out of 800 abstracts) were chosen on the basis of their applicability to the objectives of this targeted narrative review. HT during the perimenopause in women with schizophrenia ameliorates psychotic and cognitive symptoms, and may also help affective symptoms. Vasomotor, genitourinary, and sleep symptoms are also reduced. Depending on the woman's age and personal risk factors and antipsychotic side effects, the risk of breast cancer and cardiovascular disease may be increased. Antipsychotic types and doses may need to be adjusted at menopause, as may be the mode of administration. Both HT and changes in antipsychotic management should be considered for women with schizophrenia at menopause. The question about differences in response between early- and late-onset women cannot yet be answered.

    Increased frequency and severity of menopausal symptoms have been associated to black race. However, this situation has not been described in any Latin American population. Compare frequency and severity of menopausal symptoms among Afro and non-Afro Hispanic Colombian climacteric women. In this cross-sectional study, healthy Afro and non-Afro-Colombian women aged 40-59 years were asked to fill out the Menopause Rating Scale (MRS) questionnaire in order to compare symptom frequency and intensity. A total of 578 women were surveyed (201 Afro-Colombian and 377 non-Afro-Colombian). Mean age of the whole sample was 47.9+/-5.9 years (median 47), with no differences among studied groups in terms of age, parity, and hormone therapy (HT) use. Intensity of menopausal symptoms, assessed with the total MRS score, was found to be significantly higher among Afro-Colombian women (10.6+/-6.7 vs. 7.5+/-5.7, p=0.0001), which was due to higher somatic and psychological subscale scores. In this group, the frequency of somatic symptoms, heart discomfort and muscle and joint problems, was found to be higher than in non-Afro-Colombian women (38.8% vs. 26.8% and 77.1% vs. 43.5%, respectively, pColombian ones presented more bladder problems (24.9% vs. 14.9%, p=0.005). After adjusting for confounding factors, logistic regression analysis determined that black race increased the risk for presenting higher total MRS scorings (OR: 2.31; CI 95%: 1.55-3.45, p=0.0001). Despite the limitations of this study, as determined with the MRS Afro-Colombian women exhibited more impaired quality of life (QoL) when compared to non-Afro-Colombian ones, due to a higher rate and severity of menopausal somatic and psychological symptoms.

    Although epigenetic processes have been linked to aging and disease in other systems, it is not yet known whether they relate to reproductive aging. Recently, we developed a highly accurate epigenetic biomarker of age (known as the “epigenetic clock”), which is based on DNA methylation levels. Here we carry out an epigenetic clock analysis of blood, saliva, and buccal epithelium using data from four large studies: the Women's Health Initiative (n = 1,864); Invecchiare nel Chianti (n = 200); Parkinson's disease, Environment, and Genes (n = 256); and the United Kingdom Medical Research Council National Survey of Health and Development (n = 790). We find that increased epigenetic age acceleration in blood is significantly associated with earlier menopause (P = 0.00091), bilateral oophorectomy (P = 0.0018), and a longer time since menopause (P = 0.017). Conversely, epigenetic age acceleration in buccal epithelium and saliva do not relate to age at menopause; however, a higher epigenetic age in saliva is exhibited in women who undergo bilateral oophorectomy (P = 0.0079), while a lower epigenetic age in buccal epithelium was found for women who underwent menopausal hormone therapy (P = 0.00078). Using genetic data, we find evidence of coheritability between age at menopause and epigenetic age acceleration in blood. Using Mendelian randomization analysis, we find that two SNPs that are highly associated with age at menopause exhibit a significant association with epigenetic age acceleration. Overall, our Mendelian randomization approach and other lines of evidence suggest that menopause accelerates epigenetic aging of blood, but mechanistic studies will be needed to dissect cause-and-effect relationships further.

    The aim of this study was to assess menopausal symptoms and related sociodemographic conditions in middle-aged women from the Spanish province of Zaragoza. This was a cross-sectional study in which 241 women (40-59 years old) from the Zaragoza province completed the Menopause Rating Scale (MRS) and a sociodemographic questionnaire containing personal and partner data to assess symptoms associated with the menopause. The most prevalent symptoms were musculoskeletal, followed by hot flushes and perspiration. Somatic, psychological and urogenital symptoms were more severe in post-menopausal women. Somatic and urogenital symptoms worsen with age, body mass index, age at menopause, and partner age. Multiple linear regression analysis (MA) for somatic symptoms was related with the menopausal status, psychiatric treatment, problems with sexual relationships, and history of gender violence. The MA for psychological symptoms was associated with menopausal status, psychiatric treatment and a history of gender violence. The MA for urogenital symptoms was associated with menopausal status, problems with sexual relationships, urinary incontinence and partner alcohol abuse. A history of gender violence was reported by 11.6% of the women. In this sample of middle-aged women, menopausal symptoms were related to menopausal status, and other factors associated with their partner factors, including gender violence.

    Full Text Available Premises: Sexual hormones may affect the general health condition of women, as early as puberty, continuing during pregnancy and also after menopause. Variations of the hormonal levels may cause different – either local or general – pathological modifications. Sexual hormones may also affect periodontal status, favourizing gingival inflammations and reducing periodontal resistance to the action of the bacterial plaque. Scope: Establishment of the correlations between the debut or the manifestation of menopause and the modifications produced in the superficial periodontium. Materials and method: Clinical and paraclinical investigations were performed on female patients with ages between 45 and 66 years, involving macroscopic, microscopic and radiological recording of the aspect of the superificial periodontium (gingiva. Results: Analysis of the histological sections evidenced atrophic and involutive modifications in the marginal superficial periodontium of female patients at menopause. Conclusions: Sexual hormones intervene in the histological equilibrium of the marginal superficial periodontium, influencing the periodontal health status, which explains the correlation between the subjective symptomatology specific to menopause and the histopatological aspect at epithelial level.

    With increased life expectancy, today, women spend one-third of their life after menopause. Thus more attention is needed towards peri- and post-menopausal symptoms. Estrogen replacement therapy is the most effective treatment, however, it has its own limitations. The present need is to explore new options for the management of menopausal symptoms. Yogic life style is a way of living which aims to improve the body, mind and day to day life of individuals. The most commonly performed Yoga practices are postures (asana), controlled breathing (pranayama), and meditation (dhyana). Yoga has been utilized as a therapeutic tool to achieve positive health and control and cure diseases. The exact mechanism as to how Yoga helps in various disease states is not known. There could be neuro-hormonal pathways with a selective effect in each pathological situation. There have been multiple studies that have combined the many aspects of Yoga into a general Yoga session in order to investigate its effects on menopausal symptoms. Integrated approach of Yoga therapy can improve hot flushes and night sweats. There is increasing evidence suggesting that even the short-term practice of Yoga can decrease both psychological and physiological risk factors for cardiovascular disease (CVD). Studies conclude that our age old therapy, Yoga, is fairly effective in managing menopausal symptoms.

    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.

    Invitation to mammography screening of women aged 40 to 49 years is a matter of debate in many countries and a cost-effective alternative in countries without screening among women aged 40 to 49 years could be inviting those at higher risk. The relative effectiveness of mammography screening was estimated for subgroups based on the breast cancer risk factors parity, age at time of birth of first child, and socioeconomic status (SES). The SCReening of Young Women (SCRY) database consists of all women aged 40 to 49 years in Sweden between 1986 and 2005 and was split into a study and control group. The study group consisted of women residing in areas in which women aged 40 to 49 years were invited to screening and the control group of women in areas in which women aged 40 to 49 years were not invited to screening. Rate ratio (RR) estimates were calculated for 2 exposures: invitation and attendance. There were striking similarities noted in the RR pattern for women invited to and attending screening and no statistically significant difference or trend in the RR was noted by risk group. The RR estimates increased by increasing parity for parity of 0 to 2 and ranged from 0.55 (95% confidence interval [95% CI], 0.38-0.79) to 0.79 (95% CI, 0.65-0.95) for attending women. The RR for women with high SES was lower than that for women with low SES (RR, 0.72 [95% CI, 0.60-0.86] and RR, 0.79 [95% CI, 0.63-0.99], respectively). For women aged 20 to 24 years at the time of the birth of their first child, the RR was 0.73 (95% CI, 0.58-0.91) and estimates for other ages were similar. There was no statistically significant difference noted in the relative effectiveness of mammography screening by parity, age at the time of birth of the first child, or SES. © 2014 American Cancer Society.

    Women are more affected than men by many chronic pain conditions, suggesting the effect of sex-related mechanisms in their occurrence. The role of gonadal hormones has been studied but with contrasting results depending on the pain syndrome, reproductive status, and hormone considered. The aim of the present study was to evaluate the pain changes related to the menopausal transition period. In this observational study, postmenopausal women were asked to evaluate the presence of pain in their life during the premenopausal and postmenopausal periods and its modification with menopause. One hundred one women were enrolled and completed questionnaires on their sociodemographic status, pain characteristics, and evolution. The most common pain syndromes were headache (38%), osteoarticular pain (31%), and cervical/lumbar pain (21%). Pain was present before menopause in 66 women, ceased with menopause in 17, and started after menopause in 18. Data were used for cluster analysis, which allowed the division of participants into four groups. In the first, all women experienced headaches that disappeared or improved with menopause. The second group included osteoarticular pain; the pain improved in half of these women and remained stable in the other half. The third group had cervical/lumbar pain, which disappeared or improved with menopause in all. The fourth group presented different kinds of moderate pain, which worsened in all. The present study provides preliminary data suggesting that menopause can affect pain depending on the painful condition experienced by the woman. This underlines the different interactions of menopause-related events with body structures involved in pain.

    The aim of the present study was to determine age at menopause and the prevalence of menopausal symptoms among women in a community in Babol, Iran, and then identify the factors associated with these symptoms and age. A retrospective, descriptive, epidemiological study was conducted on the characteristics of perimenopausal and postmenopausal women. A total of 1,397 individuals aged 45 to 63 years were selected using a standard cluster sampling technique. The questionnaire used included menopausal symptoms, menopause status, causes of menopause, use of hormones, reproductive history, and sociodemographic factors. A standard questionnaire named Symptom ScoreCard was used to assess the frequency and severity of menopausal symptoms. The data were analyzed by χ2 analysis, t test, analysis of variance, and adjusted odds ratios with their 95% CIs. Recalled mean ± SD age at natural menopause was 47.7 ± 4.9 years. No significant difference by age at menopause was observed in sociodemographic data, smoking status, reproductive history, and oral contraceptive use. The most prevalent symptoms were irritability (72.1%), joint pain (70.6%), and depression (59.7%) during the previous 2 weeks. An increase in the percentage of occurrence and severity of some symptoms with transition to menopause was observed. The total score for menopausal symptoms was 13.0 ± 7.7. High economic situation (odds ratio, 1.89; 95% CI, 1.37-2.58) was a factor significantly associated with a total menopausal score of higher than 15. This study shows a high prevalence of menopausal symptoms and an earlier mean age at menopause (47.7 y) for women in a community in Babol, Iran. It would be beneficial to establish a menopausal clinic in primary healthcare centers for the clinical staff to monitor postmenopausal women.

    Full Text Available Abstract Background Rates of estrogen-dependent cancers are among the highest in Western countries and lower in the East. These variations may be attributable to differences in dietary exposures such as higher seaweed consumption among Asian populations. The edible brown kelp, Fucus vesiculosus (bladderwrack, as well as other brown kelp species, lower plasma cholesterol levels. Since cholesterol is a precursor to sex hormone biosynthesis, kelp consumption may alter circulating sex hormone levels and menstrual cycling patterns. In particular, dietary kelp may be beneficial to women with or at high risk for estrogen-dependent diseases. To test this, bladderwrack was administered to three pre-menopausal women with abnormal menstrual cycling patterns and/or menstrual-related disease histories. Case Presentation Intake of bladderwrack was associated with significant increases in menstrual cycle lengths, ranging from an increase of 5.5 to 14 days. In addition, hormone measurements ascertained for one woman revealed significant anti-estrogenic and progestagenic effects following kelp administration. Mean baseline 17β-estradiol levels were reduced from 626 ± 91 to 164 ± 30 pg/ml (P = 0.04 following 700 mg/d, which decreased further to 92.5.0 ± 3.5pg/ml (P = 0.03 with the1.4 g/d dose. Mean baseline progesterone levels rose from 0.58 ± 0.14 to 8.4 ± 2.6 ng/ml with the 700 mg/d dose (P = 0.1, which increased further to 16.8 ± 0.7 ng/ml with the 1.4 g/d dose (P = 0.002. Conclusions These pilot data suggest that dietary bladderwrack may prolong the length of the menstrual cycle and exert anti-estrogenic effects in pre-menopausal women. Further, these studies also suggest that seaweed may be another important dietary component apart from soy that is responsible for the reduced risk of estrogen-related cancers observed in Japanese populations. However, these studies will need to be performed in well-controlled clinical trials to confirm these

    Objectives A lifespan approach was used to evaluate age at menopause, and determinants of surgical and natural menopause, in the multi-ethnic community of Hilo, Hawaii. Study design Participants aged 40–60 years (n=898) were drawn from a larger, randomly-generated sample recruited by postal questionnaires. Median age at natural menopause was computed by probit analysis. Logistic regression analysis was applied to examine determinants of hysterectomy, and Cox regression analysis was used to examine risk factors for an earlier age at menopause. Main outcome measures History of hysterectomy, Age at menopause Results Frequency of hysterectomy was 19.2% at a mean age of 40.5 years. The likelihood of hysterectomy increased with older ages, lower education, mixed ancestry, having been overweight at age 30, and married 20 years prior to survey. Median age at natural menopause was 53.0 years. Smoking and not being married 10 years before survey were associated with an earlier age at menopause. Conclusions Median age at menopause was later than the national average. Ethnicity and education were determinants of hysterectomy, but not associated with age at natural menopause. Events later in the lifespan (e.g., smoking and not being married 10 years prior to the survey) were more important than earlier events (e.g., childhood residence) in relation to age at menopause. The timing of weight gain and marital status appear to be important in relation to surgical menopause, and the timing of marital status appears to be important in relation to the timing of natural menopause.

    Adequate vitamin D status contributes to bone fragility risk reduction and possibly other pathological conditions that occur with aging. In response to pharmaceutical vitamin D 3 supplements, several studies have documented the influence of doses, baseline status, and seasonality on serum 25-hydroyvitamin D (s25OHD). Using fortified yogurt, we investigated in one randomized controlled trial how both baseline status, as assessed by measuring s25OHD prior the onset of the trial, and the season of enrollment quantitatively influenced the response to the supplemented (Suppl.) of vitamin D 3 (VitD 3 ) in healthy community-dwelling women. A 24-week controlled trial was conducted in menopausal women (mean age: 61.5). Participants were randomized into 3 groups (Gr): Gr.Suppl.0, time controls maintaining dietary habits; Gr.Suppl.5 and Gr.Suppl.10 consuming one and two 125-g servings of VitD 3 -fortified yogurts with 5- and 10-µg daily doses, respectively. The 16 intervention weeks lasted from early January to mid-August, the 8 follow-up weeks, without product, from late August to mid-October. Before enrollment, subjects were randomized into 2 s25OHD strata: low stratum (LoStr): 25-50 nmol/L; high stratum (HiStr): >50-75 nmol/L. All enrolled participants adhered to the protocol throughout the 24-week study: Gr.Suppl.0 (n = 45), Gr.Suppl.5 (n = 44), and Gr.Suppl.10 (n = 44). Over the 16 intervention and 8 follow-up weeks, s25OHD increased in both supplemented groups, more in Gr.Suppl.10 than in Gr.Suppl.5. At the end of the intervention, the subject proportion with s25OHD ≥ 50 nmol/L was 37.8, 54.5, and 63.6% in Gr.Suppl.0, Gr.Suppl.5, and Gr.Suppl.10, respectively. The constant rate of s25OHD per supplemental VitD 3 microgram was greater in LoStr than HiStr. The s25OHD increase was greater with late (mid-March) than early (mid-January) inclusion. This randomized trial demonstrates (1) a dose-dependent s25OHD improvement related to fortified yogurt consumption; (2) an

    This article aims to review currently available evidence for women infected with human immunodeficiency virus (HIV) and menopause and to propose clinical management algorithms. Key studies addressing HIV and menopause have been reviewed, specifically age of menopause onset in HIV-infected women, frequency of menopausal symptoms, comorbidities associated with HIV and aging (including cardiovascular disease and bone disease), treatment of menopausal symptoms, and prevention of comorbidities in HIV-infected women. Studies suggest an earlier onset of menopause in HIV-infected women, with increased frequency of symptoms. Cardiovascular disease risk may be increased in this population, with combination antiretroviral therapy (cART) and chronic inflammation associated with HIV, contributing to increased risk. Chronic inflammation and cART have been independently implicated in bone disease. No published data have assessed the safety and efficacy of hormone therapy in relation to symptoms of menopause, cardiovascular risk, and bone disease among HIV-infected women. Few studies on menopause have been conducted in HIV-infected women compared with HIV-uninfected women. Many questions regarding age of menopause onset, frequency of menopausal symptoms and associated complications such as bone disease and cardiovascular disease, and efficacy of treatment among HIV-infected women remain. The incidence and severity of some of these factors may be increased in the setting of HIV and cART.

    Purpose: To disprove the common view that women who have undergone irradiation to fields excluding the pelvis are at risk for radiation-induced premature menopause, we reviewed menstrual function and fertility among women treated with subtotal lymphoid irradiation for Hodgkin's Disease. Methods and Materials: Treatment and follow-up records of all women less than age 50 at the time of diagnosis of Stage I or II supradiaphragmatic Hodgkin's Disease, treated with subtotal lymphoid irradiation alone and enrolled in radiotherapy trials from 1967 to 1985, were reviewed. In addition, patients were surveyed regarding their menstrual status and fertility history. Results: Thirty-six women, aged 10 to 40 years, with normal menstrual function at the time of Hodgkin's diagnosis, were identified. Mean follow-up was 14 years, with a range of 1.25-22.75 years. The average radiation dose to mantle and paraaortic fields was 40-44 Gy; the calculated scatter radiation dose to the pelvis at the ovaries was 3.2 Gy. There were 38 pregnancies in 18 women; all offspring are normal. One of 36 women (2.7%) experienced premature menopause. The reported rate of premature menopause in women who have not undergone irradiation is 1-3%; not significantly different than the rate in our study. There is a syndrome whereby antibodies to several endocrine organs occur (including the ovary), which is associated with premature ovarian failure. This syndrome may be associated with prior radiation to the thyroid, such as that given by mantle-irradiation for Hodgkin's Disease. We report such a case. Conclusion: There is little risk of premature menopause in women treated with radiation fields that exclude the pelvis. Women with presumed radiation-induced premature menopause warrant an evaluation to exclude other causes of ovarian failure, such as autoimmune disorders

    Depressive disorders and symptoms are common among middle-aged women. The effects of hormones on depression remain unclear. This review aims to clarify the nature of depressive disorders during the menopause transition as well as their links with climacteric syndrome, sexuality, cardiovascular risk and cognitive function. The recent literature on depressive disorders and menopause is reviewed. Women are more vulnerable than men to depressive disorders. Endocrine influences have been postulated but differences in, for example, coping style and response to stress may also contribute to the gender difference in the prevalence of depressive disorders. Gender differences in socialization may lead to higher rates of depression in women. There are data top suggest that menopause and depression are associated, although there is not a common clear causative factor. Women with climacteric symptoms (hot flushes, night sweats, vaginal dryness and dyspareunia) are more likely to report anxiety and/or depressive symptoms. Bothersome vasomotor symptoms could be associated with sleep disturbances, which in turn can increase reports of anxiety and depressive symptoms. Biopsychosocial and partner factors have a significant influence on middle-aged women's sexuality and depressive disorders, and most antidepressants can have a negative effect on sexual response. Lastly, studies have consistently shown that women with high levels of depressive symptoms are at greater cardiovascular risk and have poorer cognitive function than non-depressed women. At present, a direct relationship between psychiatric symptoms and hormonal changes such as estrogen decrease has not been clearly found. Stress, educational level, ethnicity, socioeconomic factors and partner status may influence the prevalence and clinical course of both menopause symptoms and depressive disorders. Since in many cases depression is a lifelong condition, and is associated with severe comorbid conditions, further studies are

    The incidence of cardiovascular disease increases considerably after the menopause. One reason for the increased cardiovascular risk seems to be determined by metabolic syndrome, in which all components (visceral obesity, dyslipidemia, hypertension, and glucose metabolism disorder) are associated with higher incidence of coronary artery disease. After menopause, metabolic syndrome is more prevalent than in premenopausal women, and may plays an important role in the occurrence of myocardial infarction and other atherosclerotic and cardiovascular morbidities. Obesity, an essential component of the metabolic syndrome, is also associated with increased incidence of breast, endometrial, bowel, esophagus, and kidney cancer. The treatment of metabolic syndrome is based on the change in lifestyle and, when necessary, the use of medication directed to its components. In the presence of symptoms of the climacteric syndrome, hormonal therapy, when indicated, will also contribute to the improvement of the metabolic syndrome.

  15. Reconsidering solar grid parity

    International Nuclear Information System (INIS)

    Yang, C.-J.

    2010-01-01

    Grid parity-reducing the cost of solar energy to be competitive with conventional grid-supplied electricity-has long been hailed as the tipping point for solar dominance in the energy mix. Such expectations are likely to be overly optimistic. A realistic examination of grid parity suggests that the cost-effectiveness of distributed photovoltaic (PV) systems may be further away than many are hoping for. Furthermore, cost-effectiveness may not guarantee commercial competitiveness. Solar hot water technology is currently far more cost-effective than photovoltaic technology and has already reached grid parity in many places. Nevertheless, the market penetration of solar water heaters remains limited for reasons including unfamiliarity with the technologies and high upfront costs. These same barriers will likely hinder the adoption of distributed solar photovoltaic systems as well. The rapid growth in PV deployment in recent years is largely policy-driven and such rapid growth would not be sustainable unless governments continue to expand financial incentives and policy mandates, as well as address regulatory and market barriers.

    Are parity and the timing of menarche associated with premature and early natural menopause? Early menarche (≤11 years) is a risk factor for both premature menopause (final menstrual period, FMP menopause (FMP 40-44 years), a risk that is amplified for nulliparous women. Women with either premature or early menopause face an increased risk of chronic conditions in later life and of early death. Findings from some studies suggest that early menarche and nulliparity are associated with early menopause, however overall the evidence is mixed. Much of the evidence for a direct relationship is hampered by a lack of comparability across studies, failure to adjust for confounding factors and inadequate statistical power. This pooled study comprises 51 450 postmenopausal women from nine observational studies in the UK, Scandinavia, Australia and Japan that contribute to the International collaboration for a Life course Approach to reproductive health and Chronic disease Events (InterLACE). Age at menarche (categorized as ≤11, 12, 13, 14 and 15 or more years) and parity (categorized as no children, one child and two or more children) were exposures of interest. Age at FMP was confirmed by at least 12 months of cessation of menses where this was not the result of an intervention (such as surgical menopause due to bilateral oophorectomy or hysterectomy) and categorized as premature menopause (FMP before age 40), early menopause (FMP 40-44 years), 45-49 years, 50-51 years, 52-53 years and 54 or more years. We used multivariate multinomial logistic regression models to estimate relative risk ratio (RRR) and 95% CI for associations between menarche, parity and age at FMP adjusting for within-study correlation. The median age at FMP was 50 years (interquartile range 48-53 years), with 2% of the women experiencing premature menopause and 7.6% early menopause. Women with early menarche (≤11 years, compared with 12-13 years) were at higher risk of premature menopause (RRR 1

Normal microbiota is dominated by Lactobacillus species, and pathogen microbiota such as Gardnerella species and Bacteroides species can occur due to decrease in Lactobacillus domination. Lactobacillus plays an essential role in keeping normal vaginal microbiota in balance. Vaginal microbiota adapts to pH change and hormonal value. Changes in the vaginal microbiota over a woman’s lifespan will influence the colonization of pathogenic microbes. They include changes in child, puberty, reproductive state, menopause, and postmenopause. Estrogen levels change will affect the colonization of pathogenic microbium, leading to genitourinary syndrome of menopause. Vulvovaginal atrophy is often found in postmenopausal women, and dominated by L. iners, Anaerococcus sp, Peptoniphilus sp, Prevotella sp, and Streptococcus sp. The normal vaginal microbiota’s imbalance in menopause will cause diseases such as bacterial vaginosis, and recurrent vulvovaginal candidiasis due to hormonal therapies. Changes in the vaginal microbiota due to bacterial vaginosis are characterized by decrease in H2O2-producing Lactobacillus. They are also caused by the increase in numbers and concentration of Gardnerella vaginalis, Mycoplasma hominis, and other anaerob species such as Peptostreptococci, Prevotella spp, and Mobiluncus spp.

    Full Text Available Background: Sleep is necessary in life and approximately 1/3 of human life is devoted to sleep. One of the most common problems in menopausal women is sleep disturbance. The aim of this study was to determine frequency of sleep disorders and its related factors in 50 – 60 years old women Methods: A cross-sectional, descriptive study was conducted on 200 eligible women who referred to selected health centers of Tehran University of Medical Sciences (TUMS. Demographic form, ten-point slide to review sexual satisfaction and Pittsburg Sleep Quality Index Questioner (PSQI were used for data collection. Data was analyzed using ANOVA, t-test, and Pearson correlation tests.Results: The mean age of women was 53.6±3.6 year, menopause age 47.8±4, number of children 4.76±2 and partner age was 57.99±6.6. 34.5% of women were satisfied from their sexual relationship and their score was 8-10. Rate of sleep disturbances in this group was about 70%. The results showed that between four variables: economical status, occupation, partner occupation and educational status were significantly associated with sleep disturbance (P=0.002. There was not significant difference between other demographic information and sleep disturbance.Conclusion: The results show high prevalence of sleep disturbance symptoms among menopausal women. According to the relationship between some personal characters and sleep disturbance, health care providers need to consider these variables.

    Full Text Available Objectives. This study aimed to evaluate the effect of menopausal status on the risk of metabolic syndrome (MetS in Tunisian women. Methods. We analyzed a total of 2680 women aged between 35 and 70 years. Blood pressure, anthropometric indices, fasting glucose, and lipid profile were measured. The MetS was assessed by the modified NCEP-ATPIII definition. Results. The mean values of waist circumference, blood pressure, plasma lipids, and fasting glucose were significantly higher in postmenopausal than in premenopausal women, a difference that was no longer present when adjusting for age. Except for hypertriglyceridaemia, the frequency of central obesity, hyperglycemia, high blood pressure, and high total cholesterol was significantly higher in postmenopausal than in premenopausal women. After adjusting for age, the significance persisted only for hyperglycemia. The overall prevalence of MetS was 35.9%, higher in postmenopausal (45.7% versus 25.6% than in premenopausal women. A binary logistic regression analysis showed that menopause was independently associated with MetS (OR = 1.41, 95% CI 1.10–1.82 after adjusting for age, residence area, marital status, family history of cardiovascular disease, education level, and occupation. Conclusions. The present study provides evidence that the MetS is highly prevalent in this group of women. Menopause can be a predictor of MetS independent of age in Tunisian women.

    2017-06-01

    Understanding the biosocial context of menopausal timing offers insight into social and health inequalities. Prior research on inflammatory chronic conditions suggests that inflammation may predict how early women experience menopause. We explore the ability of black race to moderate the overall relationship between chronic inflammation and timing of menopause. We use data from the National Social Life, Health, and Aging Project on inflammation, age of last menstruation, and race as well as relevant social and medical covariates. We conduct event history modeling to predict age at menopause by inflammatory biomarker levels. Using interaction analysis, we investigate whether being black may shape the overall relationship between inflammation status and menopause timing. Our analyses find no significant statistical interactions between black race and inflammation in predicting menopausal onset. However, we do identify independent correlational relationships between inflammation and black race (r = 0.136) and between menopausal timing and black race (r = -0.129) as well as inflammation (r = -0.138) that emerge as significant in corresponding regression models. We conclude that race probably does not moderate associations between inflammation and menopause. Yet, we also note that the original parameter estimate for black race's impact on menopausal onset (HR = 1.29, p menopause relationship and recommend future research using mediation modeling.

  5. From hadronic parity violation to electron parity-violating experiments

    2010-01-01

    The weak interaction is manifested in parity-violating observables. With the weak interaction extremely well known parity-violating measurements in hadronic systems can be used to deduce strong interaction effects in those systems. Parity-violating analyzing powers in electron-proton scattering have led to determining the strange quark contributions to the charge and magnetization distributions of the nucleon. Parity-violating electron-proton and electron-electron scattering can also be performed to test the predictions of the Standard Model in the 'running' of the electroweak mixing angle or sin 2 θ W .

  6. Parity horizons in shape dynamics

    Herczeg, Gabriel

    2016-01-01

    I introduce the notion of a parity horizon, and show that many simple solutions of shape dynamics possess them. I show that the event horizons of the known asymptotically flat black hole solutions of shape dynamics are parity horizons and that this notion of parity implies that these horizons possess a notion of CPT invariance that can in some cases be extended to the solution as a whole. I present three new solutions of shape dynamics with parity horizons and find that not only do event horizons become parity horizons in shape dynamics, but observer-dependent horizons and Cauchy horizons do as well. The fact that Cauchy horizons become (singular) parity horizons suggests a general chronology protection mechanism in shape dynamics that prevents the formation of closed timelike curves. (paper)

    The studies could not decisively confirm the effectiveness of various phytoestrogens inamelioration of climacteric symptoms. Most studies have proven the effectiveness of thenatural medication made of Cimicifuga racemosa and its safe short-term use. Gynecologists should be familiar with the basics of phytotherapy and the results of clinical studiesin this field in order to confidently advise women to use the natural medications in caseswhere despite the climacteric symptoms they cannot or will not use HRT, consequentlygreatly reducing the quality of their lives. In cases where climacteric symptoms are mild tomoderate, some menopausal societies around the globe suggest trying natural medicationfirst, and only later implementing HRT

  13. Self-Reported Chemotherapy-Related Cognitive Impairment Compared with Cognitive Complaints following Menopause.

    Science.gov (United States)

    Vega, Jennifer N; Dumas, Julie; Newhouse, Paul

    2018-06-15

    Cancer-related cognitive impairment (CRCI) is commonly reported following the administration of cancer treatment. Current longitudinal studies, primarily in women with breast cancer, suggest that up to 35%-60% of patients exhibit persistent CRCI (pCRCI) following completion of chemotherapy. Complaints of subjective cognitive decline (SCD) are also commonly reported by women during and following the menopause transition in non-cancer patients. Although the majority of evidence for cognitive difficulties in cancer patients and survivors is attributed to chemotherapy, there is growing evidence to suggest that menopausal status can also influence cognitive function in cancer patients. Given that menopausal status may be contributing to pCRCI, we compared a group of primarily post-menopausal women with pCRCI to two groups of post-menopausal women: women who endorse menopause-associated SCD (maSCD+) and women who do not (maSCD-) to explore the similarities/differences between maSCD and pCRCI and the potential role of menopause in pCRCI. pCRCI participants report more severe SCD symptoms than women after natural menopause, despite being on average 2.5-years post-chemotherapy, supporting previous findings that CRCI can persist for months to years after completing treatment. pCRCI participants not only endorsed greater SCD, but also exhibited objective performance differences. In addition, pCRCI participants endorsed significantly greater menopausal symptoms compared to either maSCD group. Results were not related to menopausal status prior to chemotherapy or current endocrine therapy use. These results suggest that while menopausal symptoms may contribute to SCD experienced by cancer patients after chemotherapy, they do not fully account for pCRCI.

  14. Parity violation in nuclei

    International Nuclear Information System (INIS)

    Robertson, R.G.H.

    1980-01-01

    A summary of parity violating effects in nuclei is given. Thanks to vigorous experimental and theoretical effort, it now appears that a reasonably well-defined value for the weak isovector π-nucleon coupling constant can be obtained. There is one major uncertainty in the analysis, namely the M2/E1 mixing ratio for the 2.79 MeV transition in 21 Ne. This quantity is virtually impossible to calculate reliably and must be measured. If it turns out to be much larger than 1, then a null result in 21 Ne is expected no matter what the weak interaction, so an experimental determination is urgently needed. The most promising approach is perhaps a measurement of the pair internal conversion coefficient. Of course, a direct measurement of a pure isovector case is highly desirable, and it is to be hoped that the four ΔT = 1 experiments will be pushed still further, and that improved calculations will be made for the 6 Li case. Nuclear parity violation seems to be rapidly approaching an interesting and useful synthesis

    2010-01-01

    The objective of this study was to examine the relation of menstrual attitudes to menopausal attitudes and the demographic and health characteristics associated with each. This cross-sectional study consisted of a randomly selected sample of 1824 respondents aged 16 to 100 years in multi-ethnic Hilo, Hawai`i. Women completed questionnaires for demographic and health information, such as age, ethnicity, education, residency in Hawai`i, menopausal status, exercise, and attitudes toward menstruation and menopause. Women more often chose positive terms, such as “natural,” to describe menstruation (60.8%) and menopause (59.4%). In bivariate analyses, post-menopausal women were significantly more likely to have positive menstrual and menopausal attitudes than pre-menopausal women. Factor analyses were used to cluster attitudes followed by linear regression to identify demographic characteristics associated with factor scores. Asian-American ethnicity, higher education, reporting more exercise, and growing up outside of Hawai`i were associated with positive menstrual attitudes. Higher education, older age, post-menopausal status, growing up outside of Hawai`i and having hot flashes were associated with positive menopausal attitudes. Bivariate correlation analyses suggested significant associations between factor scores for menstrual and menopausal attitudes. Both negative and positive menstrual attitudes were positively correlated with the anticipation of menopause, although negative attitudes toward menstruation were negatively correlated with menopause as a positive, natural life event. Demographic variables, specifically education and where one grows up, influenced women’s attitudes toward menstruation and menopause and should be considered for inclusion in subsequent multi-ethnic studies. Further research is also warranted in assessing the relationship between menstrual and menopausal attitudes. PMID:20853216

    The status of parity violation in the compound nucleus is reviewed. The results of previous experimental results obtained by scattering polarized epithermal neutrons from heavy nuclei in the 3-p and 4-p p-wave strength function peaks are presented. Experimental techniques are presented. The extraction of the mean squared matrix element of the parity-violating interaction, M 2 , between compound-nuclear levels and the relationship of M 2 to the coupling strengths in the meson exchange weak nucleon-nucleon potential are discussed. The tendency of measured asymmetries to have a common sign and theoretical implications are discussed. New experimental results are presented that show that the common sign phenomenon is not universal, as theoretical models developed up to now would predict

    To examine menopause transition characteristics and symptom bother in women with spinal cord injury (SCI). Prospective cohort (4 data collection periods across 4 years). Community. Women (n=62) with SCI (injury levels C6-T12, nonambulatory, >36mo postinjury; 86.1% retention) and women without SCI (n=66; 92.9% retention) with intact ovaries, not using hormone therapy, and between the ages of 45 and 60 years volunteered. A total of 505 observations were collected and analyzed. None. Age at final menstrual period (FMP), transitions through menopause status classifications, and menopause symptom bother (vasomotor, somatic, psychologic symptoms). The number of women transitioning through a menopause status classification over the course of the study did not significantly vary by group (P=.263), nor did age at FMP (P=.643). Women with SCI experienced greater bother of somatic symptoms (a subscale, P<.001), bladder infections (P<.001), and diminished sexual arousal (P=.012). Women without SCI had significantly greater bother of vasomotor symptoms (P=.020). There were no significant group by menopause status interactions; main effects for menopause status were significant only for vasomotor symptoms and vaginal dryness. Results suggested that women with SCI experience greater symptom bother in certain areas, but that patterns of symptom bother across menopause, transition through menopause, and age at FMP are similar to those of their peers. Larger studies are needed to examine menopause outcomes with respect to level of injury and completeness of injury. These findings provide a framework that women with SCI and their health care providers can use to address the menopause transition and highlight the importance of multidisciplinary involvement to maximize health and well being during this transition.

    Full text: Evidence for a meson with exotic quantum numbers J PC 1 -+ , the ρ(1405), has been observed at the AGS at Brookhaven and Crystal Barrel at CERN. This meson is exotic to the extent that its quantum numbers are not consistent with the generalised Pauli exclusion principle applied to the naive constituent quark model. In a fully relativistic field theoretic treatment, however, there is nothing in principle to preclude the existence of charge parity exotics. Using our earlier covariant Bethe-Salpeter model of light-quark mesons with no new parameter fitting we demonstrate the existence of a q - q-bar bound state with the quantum numbers of the ρ

    To describe the experience of menopausal symptoms of midlife Black women in the United States. Qualitative online forum using a feminist perspective. Internet communities for midlife women and Blacks. Twenty midlife Black women recruited using a quota sampling method. A 6-month online forum was conducted with seven discussion topics on menopausal symptoms. The discussion topics were posted sequentially on the forum site, and the women posted messages at their convenience over 6 months. The data were analyzed using thematic analysis. The identified themes were raised to be strong, accepting a natural aging process, silent and without knowledge, and our own experience. The women tried to be strong during their menopausal transitions while dealing with other important family matters. The women did not report their menopausal symptoms and were silent about or downplayed their symptoms, but many emphasized the importance of education about menopausal symptoms and highlighted their own lack of knowledge. These women generally did not talk about their symptoms because they believed that nobody except other Black midlife women could understand their menopausal experience. Health care providers need to develop a mechanism to deliver the necessary knowledge about menopausal symptoms and management strategies to Black midlife women in their health care practices.

Of 502 participating women, 92 were postmenopausal and 162 were perimenopausal.Results: Overall, 37.5% of women had a relatively favorable attitude toward menopause. African Americans had a 72% greater odds of a positive attitude (OR = 1.72, 95% CI 1.16–2.57 than all other groups after adjusting for covariates. Hispanic women had the least favorable view of menopause. Experience of >3 menopausal symptoms and negative life events—being a witness to a murder, and the death of a child—were significantly associated with negative attitudes towards menopause (OR = 0.62, 95% CI 0.42–0.93 and OR = 0.64, 95% CI 0.43–0.93, respectively. Depressive symptoms, street drug use, and having a domestic partner, which is significant in single variable analyses, did not remain independent predictors in multivariate results. HIV status, menopause status, and age at interview were not associated with menopause attitudes.Conclusions: HIV-infected, drug-using, low-income women showed generally unfavorable attitudes towards menopause. High stress life events coupled with a high prevalence of depressive symptoms indicate this population has special needs marked by the menopause transition into older age.Keywords: menopause, attitudes, HIV, street drug users

    The possible appearance of R-parity violating couplings, and hence implicitly the question of lepton and baryon number conservation, has been emphasised since the early development of supersymmetric theories. The rich phenomenology implied by R-parity violation has now gained full attention in the search for supersymmetry. In this review, theoretical and phenomenological implications of R-parity violation in supersymmetric theories are discussed, in relation with particle and astroparticle physics. Fundamental aspects include the relation with continuous and discrete symmetries, up to more recent developments on the Abelian family symmetries and hierarchy of R-parity violating couplings. The question of the generation of the standard model neutrino masses and mixings is presented. The possible contributions of R-parity violating Yukawa couplings in processes involving virtual supersymmetric particles and the resulting constraints are reviewed. Finally, a survey of the direct production of supersymmetric parti...

    Advances in computer and Internet technologies have allowed health care providers to develop, use, and test various types of Web-based interventions for their practice and research. Indeed, an increasing number of Web-based interventions have recently been developed and tested in health care fields. Despite the great potential for Web-based interventions to improve practice and research, little is known about the current status of Web-based interventions, especially those related to menopause. To identify the current status of Web-based interventions used in the field of menopause, a literature review was conducted using multiple databases, with the keywords "online," "Internet," "Web," "intervention," and "menopause." Using these keywords, a total of 18 eligible articles were analyzed to identify the current status of Web-based interventions for menopause. Six themes reflecting the current status of Web-based interventions for menopause were identified: (a) there existed few Web-based intervention studies on menopause; (b) Web-based decision support systems were mainly used; (c) there was a lack of detail on the interventions; (d) there was a lack of guidance on the use of Web-based interventions; (e) counselling was frequently combined with Web-based interventions; and (f) the pros and cons were similar to those of Web-based methods in general. Based on these findings, directions for future Web-based interventions for menopause are provided. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Premature menopause refers to the occurrence of menopause in women less than 40 years of age. This heterogeneous disorder affects 1 percent and 0.1 percent of women less than 40 and 30 years of age, respectively. The study reported in this article attempts to understand the prevalence and determinants of premature menopause among Indian women by studying the effects of various socioeconomic indicators, such as age, education, wealth index, rural-urban settlement, work status, religion, and caste, on women. The study analyzed the National Family Health Survey-3, which is equivalent to the Demographic Health Survey in India. Bivariate and logistic regression analyses were performed to tease out the determinants of premature menopause. Results indicate that the percentage of premature menopause is very high (5.5 percent) among Indian women. Among Indian states, Andhra Pradesh women have the highest percentage of premature menopause (14.6 percent). Smoking and the nutritional status of women are strongly associated with early menopause. Furthermore, women living in rural areas and using tobacco are at a greater risk of premature menopause. © 2017 National Association of Social Workers.

    Full Text Available Background The aim of this study was to evaluate the occurrence and intensity of menopausal symptoms, taking into account the length of one’s relationship, its nature and one’s assessment of it. Participants and procedure The study included 200 women between the ages of 45 and 68, with secondary or higher education, married or in cohabiting relationships. Women were divided into three groups depending on the experience related to menopause: premenopause (46 respondents, perimenopause (75 respondents, and postmenopause (79 respondents. The study used a survey of self-design, the “Women’s Health” Questionnaire (WHQ by M. Hunter, and the “Partner Relations Questionnaire” (PFB by K. Hahlweg. Results Most menopausal symptoms – including those of the greatest severity – are experienced by women in perimenopausal and postmenopausal phases, but one’s own relationship’s assessment is the lowest in postmenopausal women. In this group of women, relevant and significant relations between the dimensions of the quality of the relationship and the menopausal symptoms are the most numerous. The most essential assessment was the one relating to intimacy – its poor evaluation is accompanied by higher intensity of experienced depression symptoms, somatic symptoms, and disorders of memory and concentration, sex and sleep, and also the sum of menopausal symptoms is higher. In all three groups, no significant differences in the severity of menopausal symptoms were observed between women in marital and cohabiting relationships. In women in the perimenopausal phase, the shorter the length of the relationship (its seniority, the greater is the severity of sexual dysfunction symptoms, whereas in women in the postmenopausal stage, along with the length of the relationship, the severity of psychological and somatic symptoms increases. Conclusions One should find that the perimenopausal and postmenopausal phases are particularly difficult for women

    Objective The general consensus has been that estrogen is invariably a risk factor for ischemic stroke (IS). We reviewed new observational studies that challenge this simple conclusion. Methods This was a review of observational studies of the association of premature or early menopause with stroke or IS published in English from 2006 through 2010. Results Three cohort studies showed an increased risk of all stroke in women who underwent bilateral oophorectomy compared with women who conserved their ovaries before age 50 years. The increased risk of stroke was reduced by hormonal therapy (HT) in one of the studies, suggesting that estrogen deprivation is involved in the association. Four additional observational studies showed an association of all stroke or IS with the early onset of menopause or with a shorter lifespan of ovarian activity. In three of the seven studies, the association was restricted to IS. Age at menopause was more important than type of menopause (natural vs induced). Conclusions The findings from seven recent observational studies challenge the consensus that estrogen is invariably a risk factor for IS and can be reconciled by a unifying timing hypothesis. We hypothesize that estrogen is protective for IS before age 50 years and may become a risk factor for IS after age 50 years or, possibly, after age 60 years. These findings are relevant to women who experienced premature or early menopause, or to women considering prophylactic bilateral oophorectomy before the onset of natural menopause. PMID:21993082

    The aim of this study was to determine the influence of menopause (hypoestrogenism) as a risk factor for oxidative stress. We carried out a cross-sectional study with 187 perimenopausal women from Mexico City, including 94 premenopausal (mean ± SD age, 44.9 ± 4.0 y; estrogen, 95.8 ± 65.7 pg/mL; follicle-stimulating hormone, 13.6 ± 16.9 mIU/mL) and 93 postmenopausal (mean ± SD age, 52.5 ± 3.3 y; estrogen, 12.8 ± 6.8 pg/mL; follicle-stimulating hormone, 51.4 ± 26.9 mIU/mL) women. We measured lipoperoxides using a thiobarbituric acid-reacting substance assay, erythrocyte superoxide dismutase and glutathione peroxidase activities, and the total antioxidant status with the Randox kit. An alternative cutoff value for lipoperoxide level of 0.320 μmol/L or higher was defined on the basis of the 90th percentile of young healthy participants. All women answered the Menopause Rating Scale, the Athens Insomnia Scale, and a structured questionnaire about pro-oxidant factors, that is, smoking, consumption of caffeinated and alcoholic beverages, and physical activity. Finally, we measured weight and height and calculated body mass index. The lipoperoxide levels were significantly higher in the postmenopausal group than in the premenopausal group (0.357 ± 0.05 vs 0.331 ± 0.05 μmol/L, P = 0.001). Using logistic regression to control pro-oxidant variables, we found that menopause was the main risk factor for oxidative stress (odds ratio, 2.62; 95% CI, 1.35-5.11; P menopause rating score, insomnia score, and lipoperoxides, and this relationship was most evident in the postmenopausal group (menopause scale, r = 0.327 [P = 0.001]; insomnia scale, r = 0.209 [P < 0.05]). Our findings suggest that the depletion of estrogen in postmenopause could cause oxidative stress in addition to the known symptoms.

    Thirty post-menopausal women with breast abscess were treated at Port of Spain General Hospital, Trinidad, between 1976 and 1980. In this age group, breast abscess can be confused with cancer due to a lack of inflammatory features. History and physical examination are often not helpful in differentiating an abscess from carcinoma. Although the usual treatment of an abscess is incision and drainage, in post-menopausal women, excision of the lesion is helpful for accurate histological diagnosis.

    With longitudinally polarized protons at RHIC, even a 1 month dedicated run utilizing both approved major detectors could produce a significant search for new physics in hadron collisions via parity violation. Additionally, in the energy range of RHIC, large ''conventional'' parity violating effects are predicted due to the direct production of the weak bosons W ± and Z 0 . One can even envision measurements of the spin dependent sea-quark structure functions of nucleons using the single-spin parity violating asymmetry of W ± and Z 0

    The study objectives were to examine the association between menopause status and diabetes risk among women with glucose intolerance and to determine if menopause status modifies response to diabetes prevention interventions. The study population included women in premenopause (n = 708), women in natural postmenopause (n = 328), and women with bilateral oophorectomy (n = 201) in the Diabetes Prevention Program, a randomized placebo-controlled trial of lifestyle intervention and metformin among glucose-intolerant adults. Associations between menopause and diabetes risk were evaluated using Cox proportional hazard models that adjusted for demographic variables (age, race/ethnicity, family history of diabetes, history of gestational diabetes mellitus), waist circumference, insulin resistance, and corrected insulin response. Similar models were constructed after stratification by menopause type and hormone therapy use. After adjustment for age, there was no association between natural menopause or bilateral oophorectomy and diabetes risk. Differences by study arm were observed in women who reported bilateral oophorectomy. In the lifestyle arm, women with bilateral oophorectomy had a lower adjusted hazard for diabetes (hazard ratio [HR], 0.19; 95% CI, 0.04-0.94), although observations were too few to determine if this was independent of hormone therapy use. No significant differences were seen in the metformin (HR, 1.29; 95% CI, 0.63-2.64) or placebo arms (HR, 1.37; 95% CI, 0.74-2.55). Among women at high risk for diabetes, natural menopause was not associated with diabetes risk and did not affect response to diabetes prevention interventions. In the lifestyle intervention, bilateral oophorectomy was associated with a decreased diabetes risk.

    We explore the possibility that well known properties of the parity operator, such as its idempotency and unitarity, might break down at the Planck scale. Parity might then do more than just swap right and left polarized states and reverse the sign of spatial momentum k: it might generate superpositions of right and left handed states, as well as mix momenta of different magnitudes. We lay down the general formalism, but also consider the concrete case of the Planck scale kinematics governed by κ-Poincaré symmetries, where some of the general features highlighted appear explicitly. We explore some of the observational implications for cosmological fluctuations. Different power spectra for right handed and left handed tensor modes might actually be a manifestation of deformed parity symmetry at the Planck scale. Moreover, scale-invariance and parity symmetry appear deeply interconnected.

    The experience of menopause can vary strongly from one society to another: frequency of hot flushes, other somatic and psychological symptoms, and changes in family and social relations. Several studies have shown that country of residence, country of birth, ethnicity, and social class all play roles in these variations. But few comparative anthropological studies have analysed the social processes that construct the experience of menopause or considered menopausal women's social and financial autonomy. To study the impact of the social status accorded to menopausal women and their social resources, during 2007 and 2008 we conducted a series of 75 in-depth interviews with women in different sociocultural settings: Tunisian women in Tunisia, Tunisian women in France, and French women in France, all aged from 45 to 70 years. Our methodological approach to the data included content analysis, typology development and socio-demographic analysis. Quite substantial differences appeared, as a function of social class and cultural environment. We identified three principal experiences of menopause. Tunisian working class women, in Tunisia and France, experience menopause with intense symptoms and strong feelings of social degradation. Among Tunisian middle-class women in both countries, menopause was most often accompanied by a severe decline in aesthetic and social value but few symptoms. For most of the French women, menopause involved few symptoms and little change in their social value. The distribution of types of experiences according to social but not geographic or national factors indicates that, in the populations studied here, the differences in symptoms are not biologically determined. Different experiences of menopause are linked to social class and to the degree of male domination. A given level of independence and emancipation allows women an identity beyond their reproductive function and a status unimpaired by menopause. Copyright © 2012 Elsevier Ltd. All

    To investigate natural spontaneous menopausal age, menstruation span and their relationship with menarche age and parity in Pudong district of Shanghai. From Jan 2007 to Jul 2008, 15 083 spontaneous menopause women undergoing cervical cancer screening were enrolled in this study. The questionnaire included menarche age, parity, spontaneous menopausal age and menstruation span. Those women were divided into four groups based on age, which were group of 56 - 60, 61 - 65, 66 - 70 and more than 70.Analysis of variance (ANOVA) was used for comparing difference between menopausal age and menstruation span. Multiple factor regressions was used to analyze the relationship between menarche age, parity and menopausal age and menstruation span. (1) Spontaneous menopausal age: the minimum was 29 years old, the maximum was 61 years old, and the mean age was (50.6 ± 3.7) years old. The mean spontaneous menopause age were (50.9 ± 3.4), (50.7 ± 3.7), (50.0 ± 4.1), (49.6 ± 4.0) years in groups of 56 - 60, 61 - 65, 66 - 70 and more than 70 years. With the increasing age range in four groups, the increasing trends of menopausal age were observed, which the difference of 1.36 year was shown between groups of 56 - 60 and more than 70 years. (2) Menstruation span: the mean of menstruation span was (34.3 ± 4.1) years, which the minimal age of 12 years and maximal age of 48 years were recorded. (34.6 ± 3.8), (34.3 ± 4.1), (33.9 ± 4.6), (33.2 ± 4.5) were observed in groups of 56 - 60, 61 - 65, 66 - 70 and more than 70 years. With the increasing age range in four groups, the increasing trends of menstruation span were observed, which the difference of 1.41 year was shown between groups of 56 - 60 and more than 70 years. (3) The impact of menarche age on menopausal age and menstruation span: there was no correlation between menarche age and menopausal age (r = 0.02); however, menstruation span was found to be negatively correlated with the menarche age (r = -0.43).

    To assess the sex ratio in offspring of smoking and nonsmoking mothers in relationship to parity. Prospective study. University hospital. The authors studied 2,108 term singleton neonates born between 1993 and 2002, 665 from smoking mothers and 1,443 from nonsmoking mothers. A prospective recording of maternal age, parity and smoking status, and gender of neonates delivered over a 10-year period. Secondary sex ratio in regard to maternal smoking and parity. The offspring sex ratio in the total sample studied was 1.09; in the offspring of smoking and nonsmoking mothers, it was 1.26 and 1.03, respectively, a statistically significant difference. In the offspring of smoking women who had parity 1, 2, and >or=3, it was 1.47, 1.35, and 0.92, whereas in those of nonsmoking women, it was 1.04, 1.00, and 1.03, respectively (the differences of the parity 1 and 2 groups between the offspring of smoking and nonsmoking mothers were statistically significant). Logistic regression analysis showed that the possibility of a boy being delivered by a mother who smoked was significantly greater in primiparous women than in women who had parity >or=3, independent of the maternal age. Conversely, parity did not affect significantly the sex ratio in the offspring of nonsmoking women. The findings suggest that among women who smoked, significantly more male than female offspring are born from primiparous women, whereas women who had parity >or=3 gave birth to more female offspring; biparous women give birth to significantly more male offspring, but the offspring sex ratio declined with the number of cigarettes when the mothers smoked >or=10 cigarettes per day.

  5. Induced abortion ratio in modern Sweden falls with age, but rises again before menopause.

    A woman's reproductive value decreases over her reproductive life span and it is therefore predicted that the likelihood of termination of investment in a child decreases with increasing age. An eventual increase in termination ratio in the oldest age groups, as is often found in abortion statistics, could depend on older women on average having larger families rather than on age per se. We used data on abortions and births in Sweden during 1994 to investigate how abortion ratio is related to age and parity of women. We found that age-specific abortion ratio is U-shaped (i.e. that it is highest for the youngest and for the oldest age groups) in each parity class from zero to four children but that age-dependence breaks down in higher parity classes (5, >/=6). Thus, for each of the parity classes 0-4, the incidence of abortion decreases with age up to a point, but increases again as women approach menopause. This late increase in induced abortion ratio seems to depend on age per se. The data indicate that abortion ratio is an inverse function of fertility, and that investment in new reproduction gradually decreases as a woman approaches menopause. Assuming grandmothering as an important driving force in human life history evolution, such a pattern might indicate that the transition from behavioural investment in one's own children to one's grandchildren is a gradual process similar to the decline in ovarian function.

Searching articles indexed in Pubmed, Science Direct, Iranmedex, EMBASE, Scopus, and Scientific Information Database databases, a total number of 42 studies published between 2003 and 2013 were selected. Age, estrogen deficiency, type of menopause, chronic medical problems, partner's sex problems, severity of menopause symptoms, dystocia history, and health status were the physical factors influencing sexual function of menopausal women. There were conflicting results regarding the amount of androgens, hormonal therapy, exercise/physical activity, and obstetric history. In the mental–emotional area, all studies confirmed the impact of depression and anxiety. Social factors, including smoking, alcohol consumption, the quality of relationship with husband, partner's loyalty, sexual knowledge, access to health care, a history of divorce or the death of a husband, living apart from a spouse, and a negative understanding of women's health were found to affect sexual function; however, there were conflicting results regarding the effects of education, occupation, socioeconomic status, marital duration, and frequency of sexual intercourse.

    2005-01-01

    The present study examined the relationships among physical activity (PA), symptom reporting, self-esteem, and satisfaction with life (SWL) in 133 women (M age=51.12, S.D.=4.10) of varying menopausal status. Multivariate analyses of co-variance (MANCOVA) revealed that independent of menopausal status, women who were more physically active reported significantly less severe vaso-somatic and general somatic symptoms, and higher levels of physical self-worth (PSW). Subsequent hierarchical regression analyses indicated that expended MET-h/week, reported symptoms (frequency and severity, respectively), and PSW accounted for significant variance in SWL (R2 model=0.32, for symptom frequency, and 0.33, for symptom severity). Physical activity was significantly related to SWL through the mediation of PSW. However, both reported symptom frequency and severity retained significant association with SWL after controlling for PSW, although the original associations were significantly reduced. Finally, both symptoms and MET-h/week were independent contributors to the variance in PSW (R2 model=0.33 and 0.34). The results suggest that being physically active may reduce perceived severity of menopausal symptoms and enhance psychological well-being, and that the relationship between physical activity and QOL in mid-life women may be mediated by factors such as physical self-perceptions and menopausal symptoms.

To this end, two methods are applied. The first consists of breaking the variance of rids down into relative purchasing power pariety and uncovered interest rate parity and shows that inflation differentials are the main source of rids variation; while the second method breaks down the rids and nominal interest rate differentials (nids into nominal and real shocks. Bivariate autoregressive models are estimated under particular identification conditions, having been adequately treated for the identified structural breaks. Impulse response functions and error variance decomposition result in real shocks as being the likely cause of rids.O objetivo deste artigo é investigar as causas gerais dos diferenciais da taxa de juros real (rids para um conjunto de países emergentes, para o período de janeiro de 1996 a agosto de 2007.

    The aim of this study was to determine whether older postmenopausal women with a history of bilateral oophorectomy before natural menopause (surgical menopause) have a higher risk of nonvertebral postmenopausal fracture than women with natural menopause. We used 21 years of prospectively collected incident fracture data from the ongoing Study of Osteoporotic Fractures, a cohort study of community-dwelling women without previous bilateral hip fracture who were 65 years or older at enrollment, to determine the risk of hip, wrist, and any nonvertebral fracture. χ(2) and t tests were used to compare the two groups on important characteristics. Multivariable Cox proportional hazards regression models stratified by baseline oral estrogen use status were used to estimate the risk of fracture. Baseline characteristics differed significantly among the 6,616 women within the Study of Osteoporotic Fractures who underwent either surgical (1,157) or natural (5,459) menopause, including mean age at menopause (44.3 ± 7.4 vs 48.9 ± 4.9 y, P menopause, even among women who had never used oral estrogen (hip fracture: hazard ratio [HR], 0.87; 95% CI, 0.63-1.21; wrist fracture: HR, 1.10; 95% CI, 0.78-1.57; any nonvertebral fracture: HR, 1.11; 95% CI, 0.93-1.32). These data provide some reassurance that the long-term risk of nonvertebral fracture is not substantially increased for postmenopausal women who experienced premenopausal bilateral oophorectomy, compared with postmenopausal women with intact ovaries, even in the absence of postmenopausal estrogen therapy.

    Large numbers of women transition through menopause whilst in paid employment. Symptoms associated with menopause may cause difficulties for working women, especially if untreated, yet employers are practically silent on this potentially costly issue. This review summarises existing research on the underexplored topic of menopause in the workplace, and synthesises recommendations for employers. Longstanding scholarly interest in the relationship between employment status and symptom reporting typically (but not consistently) shows that women in paid employment (and in specific occupations) report fewer and less severe symptoms than those who are unemployed. Recent studies more systematically focused on the effects of menopausal symptoms on work are typically cross-sectional self-report surveys, with a small number of qualitative studies. Though several papers established that vasomotor (and associated) symptoms have a negative impact on women's productivity, capacity to work and work experience, this is not a uniform finding. Psychological and other somatic symptoms associated with menopause can have a relatively greater negative influence. Physical (e.g., workplace temperature and design) and psychosocial (e.g., work stress, perceptions of control/autonomy) workplace factors have been found to influence the relationship between symptoms and work. Principal recommendations for employers to best support menopausal women as part of a holistic approach to employee health and well-being include risk assessments to make suitable adjustments to the physical and psychosocial work environment, provision of information and support, and training for line managers. Limitations of prior studies, and directions for future research are presented. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available In 2010, nearly 400 million women worldwide were of menopause age (45-54. Although many women transition through menopause with ease, some experience distress and a subsequent decrease in quality of life. The purpose of this qualitative study was to examine the experiences of distress in women during the menopause transition. A narrative analysis methodology was used maintaining participants’ complete narratives when possible. In-person interviews of 15 midlife women were digitally audio recorded and transcribed verbatim. Women shared narratives of distress related to menstrual changes, emotional instability, vaginal dryness, and decreased libido affected by their relationships with self, partners, work, and family. Some experiences were presented against a backdrop of the past and influenced by concerns for the future. Detailed stories illuminated the effect that distressful symptoms had on quality of life and captured how intricately woven symptoms were with the women’s interpersonal and social lives.

  18. [Menopause: Hypertension and vascular disease].

    Science.gov (United States)

    Zilberman, J M

    Hypertension is the main cardiovascular risk factor affecting 25% of women. Hormone changes and hypertension after menopause may lead to higher target organ damage and cardiovascular disease such as increased arterial stiffness, coronary diseases, chronic heart failure and stroke. The physiopathological mechanisms involved in the development of hypertension and cardiovascular diseases in menopausal women are controversial. There are pharmacokinetic and pharmacodynamic differences in both sexes, the women have more coughing when using the converting-enzyme inhibitors, more cramps when using thiazide diuretics and more oedema in the inferior limbs when using calcium antagonists. The aim of this review is to analyse possible physiopathological mechanisms involved in hypertension after menopause and to gain a better understanding of the biological effects mediated by vascular ageing in women when the level of oestrogen protective effect decreases over the vascular system.

    2016-09-01

    For over a century it has been well documented that bacteria in the vagina maintain vaginal homeostasis, and that an imbalance or dysbiosis may be associated with poor reproductive and gynecologic health outcomes. Vaginal microbiota are of particular significance to postmenopausal women and may have a profound effect on vulvovaginal atrophy, vaginal dryness, sexual health and overall quality of life. As molecular-based techniques have evolved, our understanding of the diversity and complexity of this bacterial community has expanded. The objective of this review is to compare the changes that have been identified in the vaginal microbiota of menopausal women, outline alterations in the microbiome associated with specific menopausal symptoms, and define how hormone replacement therapy impacts the vaginal microbiome and menopausal symptoms; it concludes by considering the potential of probiotics to reinstate vaginal homeostasis following menopause. This review details the studies that support the role of Lactobacillus species in maintaining vaginal homeostasis and how the vaginal microbiome structure in postmenopausal women changes with decreasing levels of circulating estrogen. In addition, the associated transformations in the microanatomical features of the vaginal epithelium that can lead to vaginal symptoms associated with menopause are described. Furthermore, hormone replacement therapy directly influences the dominance of Lactobacillus in the microbiota and can resolve vaginal symptoms. Oral and vaginal probiotics hold great promise and initial studies complement the findings of previous research efforts concerning menopause and the vaginal microbiome; however, additional trials are required to determine the efficacy of bacterial therapeutics to modulate or restore vaginal homeostasis.

    In Fukuoka Prefecture, in south-western Japan, a regional screening program for osteoporosis was conducted from 1994 to 1995. The screening level in the bone mineral density (BMD) at the distal non-dominant radius was equal to or less than two standard deviations below age-specific mean (≤ -2.0 SD). In 1177 examinees with natural menopause (mean age: 61.4, range: 42-88), 56 of those who were screened were subsequently radiologically confirmed by orthopedic specialists to have osteoporosis (case group). They were then compared with 802 normal BMD (≥ -1.0 SD) women (reference group) with their lifestyle and reproductive characteristics. The adjusted odds ratio (OR) and its 95% confidence interval (CI) were calculated using a logistic regression model. A significant increase in the ORs for osteoporosis based on the number of years since menopause was observed for 7-13 years since menopause (OR=2.3; 95% CI: 1.0-5.4) compared with <7 years, however, no increasing trend in risk was evident in 14+ years since menopause (OR=1.4; 95% CI: 0.4-5.1). Thus, the elevated risk continued up to around 10 years since menopause. These findings are consistent with previous studies that reported an alternation in the calcium metabolism and bone loss related to the length of time after menopause. Both the childhood and current milk consumption were also associated with a decreased risk: ORs were 0.4 (95% CI: 0.2-0.9) and 0.5 (95% CI: 0.3-1.0), respectively

    Chronic exposure to arsenic is associated with neoplastic, cardiovascular, endocrine, neuro-developmental disorders and can have an adverse effect on women's reproductive health outcomes. This study examined the relationship between arsenic skin lesions (a hallmark sign of chronic arsenic poisoning) and age of natural menopause (final menopausal period) in populations with high levels of arsenic exposure in Bangladesh. We compared menopausal age in two groups of women--with and without arsenic skin lesions; and presence of arsenic skin lesions was used as an indicator for chronic arsenic exposure. In a cross-sectional study, a total of 210 participants were randomly identified from two ongoing studies--participants with arsenic skin lesions were identified from an ongoing clinical trial and participants with no arsenic skin lesions were identified from an ongoing cohort study. Mean age of menopause between these two groups were calculated and compared. Multivariable linear regression was used to estimate the relationship between the status of the arsenic skin lesions and age of natural menopause in women. Women with arsenic skin lesions were 1.5 years younger (p <0.001) at the time of menopause compared to those without arsenic skin lesions. After adjusting with contraceptive use, body mass index, urinary arsenic level and family history of premature menopause, the difference between the groups' age at menopause was 2.1 years earlier (p <0.001) for respondents with arsenic skin lesions. The study showed a statistically significant association between chronic exposure to arsenic and age at menopause. Heavily exposed women experienced menopause two years earlier than those with lower or no exposure.

    Younger age at menopause is associated with overall mortality, and cigarette smoking is the only lifestyle factor influencing this association. However, the combined effects of age at menopause and smoking have never been quantified in terms of survival time. Our aim was to evaluate, in a large cohort of Swedish women, differences in age at death according to age at menopause and smoking status. Age at menopause and smoking were assessed, using a self-administered questionnaire, in a population-based cohort of 25,474 women aged 48 to 83 years. Laplace regression was used to calculate differences in median age at death (50th percentile difference [PD]) according to smoking and age at menopause. Across 16 years of follow-up, 5,942 participants died. The difference in median age at death between women with menopause at 40 years and women with menopause at 60 years was 1.3 years (50th PD, 1.3; 95% CI, 0.3-2.2). Compared with current smokers, former smokers and never smokers had older median age at death-2.5 years (50th PD, 2.5; 95% CI, 1.9-3.1) and 3.6 years (50th PD, 3.6; 95% CI, 3.1-4.1), respectively. When analysis was restricted to current smokers, the difference in age at death between women with menopause at 40 years and women with menopause at 60 years increased to 2.6 years (50th PD, 2.6; 95% CI, 0.8-4.5). No association among never smokers was observed. Younger age at menopause is linearly associated with shorter survival. This association tends to be stronger among current smokers.

    Menopause coincides with an increase in the incidence of hypertension in women. A direct role of estrogen deprivation in this increased blood pressure remains a topic of debate. Menopause probably accelerates the arterial changes related to aging. Hormone replacement therapy does not influence blood pressure significantly and is not contraindicated in hypertensive women. The effect of hormone replacement treatment on cardiovascular risk was recently the object of controversy. It does not increase risk except in cases of late treatment in older women who already have atherosclerosis. Hypertension management in women is otherwise similar to management in men.

  4. Chirality and gravitational parity violation.

    2015-06-01

    In this review, parity-violating gravitational potentials are presented as possible sources of both true and false chirality. In particular, whereas phenomenological long-range spin-dependent gravitational potentials contain both truly and falsely chiral terms, it is shown that there are models that extend general relativity including also coupling of fermionic degrees of freedom to gravity in the presence of torsion, which give place to short-range truly chiral interactions similar to that usually considered in molecular physics. Physical mechanisms which give place to gravitational parity violation together with the expected size of the effects and their experimental constraints are discussed. Finally, the possible role of parity-violating gravity in the origin of homochirality and a road map for future research works in quantum chemistry is presented. © 2015 Wiley Periodicals, Inc.

  6. Parity nonconservation and nuclear polarizabilities

    International Nuclear Information System (INIS)

    Haxton, W.

    1990-01-01

    The hadronic weak interaction contributes to parity nonconserving observables in semileptonic interactions. Weak nuclear polarizabilities are frequently important in such interactions. Some of the interesting physics is illustrated by 18 F, a nucleus that provides an important constraint on the neutral weak hadronic current. One observable where the nuclear polarizability is expected to dominate is the nuclear anapole moment. The long-range pion contribution to this weak radiative correction is explored for both nucleons and nuclei. Similar polarizabilities that arise for time-reversal-odd hadronic interactions that conserve or violate parity are discussed in connection with atomic electric dipole moments. 20 refs., 4 figs

    Synchronization of neural networks has been studied in recent years as an alternative to cryptographic applications such as the realization of symmetric key exchange protocols. This paper presents a first view of the so-called permutation parity machine, an artificial neural network proposed as a binary variant of the tree parity machine. The dynamics of the synchronization process by mutual learning between permutation parity machines is analytically studied and the results are compared with those of tree parity machines. It will turn out that for neural synchronization, permutation parity machines form a viable alternative to tree parity machines

    To evaluate lenticular oxidative stress in rat menopausal models. Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Group 1). From the rats that underwent oophorectomy, 10 formed the menopause control group (Group 2), 10 were administered a daily injection of methylprednisolone until the end of the study (Group 3), and the remaining 10 rats were administered intraperitoneal streptozocin to induce diabetes mellitus (Group 4). Total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) measurements of the crystalline lenses were analyzed. The mean OSI was the lowest in group 1 and highest in group 4. Nevertheless, the difference between the groups was not statistically significant in terms of OSI (p >0.05). The mean TOS values were similar between the groups (p >0.05), whereas the mean TAC of group 1 was significantly higher than that of the other groups (p <0.001). Our results indicate that menopause may not promote cataract formation.

    Full Text Available Menopause is a natural part of the aging process in women and is defined as occurring 12 months after the last menstrual period marking the end of menstrual cycles. Menopause has a negative impact on the quality of life (QoL. Various generic and specific questionnaires have been used for assessing different dimensions of QoL in menopausal women. The purpose of this systematic review was to identify those general and specific instruments, and to determine the factors that affect QoL in menopausal women. We assessed eight specific and three general tools and found that some general and specific instruments, such as the 36-item short form (SF-36 and the Menopause Specific Quality of Life Questionnaire (MENQOL, were mostly used for assessment. The specific tools available were diverse. Employment status and a high educational level in menopausal women were considered to be protective factors in improving QoL. Identification of predicting factors of QoL, such as body mass index, race, age, duration of menopause, and social and occupational variables can help to improve the QoL of these women allowing planning of psychological consultations and practical interventions.

    We show that many supersymmetric models may spontaneously break R parity through scalar neutrinos acquiring a vacuum expectation value (vev). These models allow supersymmetric particles to be produced singly and to decay to nonsupersymmetric states. This leads to a new pattern of supersymmetric phenomenology. We discuss the lepton number violation to be expected in this class of models. (orig.)

    There is a global trend of increasing numbers of older women in the workforce. However, limited information is available regarding the relationship between the menopause transition and work, especially in developing countries. The objectives of this study were to investigate the relationship between experience of the menopause transition and work and to examine the factors affecting how women cope, including the extent to which women disclosed their menopausal status. Using a cross-sectional single group design, 131 middle-aged female medical teaching staff working in Zagazig Faculty of Medicine completed questionnaires and semi-structured interviews. Participants, particularly those who were postmenopausal, reported high average scores on depressed mood, memory/concentration, sleep problems, vasomotor symptoms, and sexual behavior subscales of the Women's Health Questionnaire (WHQ). Women reported that poor working environment and work policies and conditions, functioning as sources of work stress, aggravated their menopausal symptoms. Disclosure of their menopausal status was uncommon; limited time and socio-cultural barriers were the most commonly reported reasons for non-disclosure. It could be concluded that the menopause transition is an important occupational health issue especially for women in developing countries. Implementing health promotion programs, improving working environment and work policies, and raising awareness of menopause are recommended to help women to cope with the menopause transition and to maintain well-being and productivity at work.

Namun demikian, masih diperlukan penelitian lain dengan menggunakan desain penelitian kohort prospektif untuk dapat melihat hubungan temporal antara lama penggunaan kontrasepsi pil terhadap usia menopause. Menopause is marked with the permanent cessation of menstruation due to the loss of follicles. Earlier menopause will be likely to increase the risk factors relating to declined estrogen level, such as osteoporosis that can lead to early death. Awoman entering menopause period often experiences declined estrogen hormone that causes her to have complaints or disturbances that hinder her daily activities and even reduce her quality of life. However, the use of oral contraceptive poses a correlation with the postponing of menopause age and complaints. The primary aim of this study was to examine the relation of oral contraceptive use and age at menopause. This was an observational study with cross-sectional study design. Population in

    We investigated whether younger age at natural menopause confers a risk of heart failure. We also examined a possible modifying effect of tobacco smoking. This study used the population-based Swedish Mammography Cohort; 22,256 postmenopausal women with information on age at natural menopause were followed from 1997 through 2011. First event of heart failure was ascertained through the Swedish National Patient Register and the Cause of Death Register. Cox proportional hazards regression analyses were conducted to estimate multivariable-adjusted hazard ratios (HRs) and 95% CIs. During a mean follow-up of 13 years, we ascertained 2,532 first events of heart failure hospitalizations and deaths. The mean age at menopause was 51 years. Early natural menopause (40-45 y), compared with menopause at ages 50 to 54 years, was significantly associated with heart failure (HR, 1.40; 95% CI, 1.19 to 1.64). In analyses stratified by smoking status, similar HRs were observed for this age group among never smokers (HR, 1.33; 95% CI, 1.06 to 1.66) and ever smokers (HR, 1.39; 95% CI, 1.09 to 1.78). Among ever smokers, increased incidence (HR, 1.25; 95% CI, 1.06 to 1.47) of heart failure could be detected even among those who entered menopause at ages 46 to 49 years. We found a significant interaction between age at natural menopause and smoking (P = 0.019). This study indicates that women who experience early natural menopause are at increased risk for developing heart failure and that smoking can modify the association by increasing the risk even among women who enter menopause around ages 46 to 49 years.

    We compared the prevalence of menopause symptoms between women living with HIV to their HIV-negative peers and determined predictors of severe menopause symptoms in Jos, Nigeria. This descriptive cross-sectional study included 714 women aged 40-80 years. We compared prevalence and severity of menopause symptoms using the menopause rating scale (MRS). Logistic regression analysis was used to determine the predictors of severe symptoms. Six-hundred and seven (85.0%) were HIV-positive, with a mean duration of infection of 5.6 ± 2.7 years. The mean age of the cohort was 46 ± 5 years. The most prevalent menopause symptoms were hot flushes (67.2%), joint and muscle discomfort (66.2%), physical/mental exhaustion (65.3%), heart discomfort (60.4%), and anxiety (56.4%). The median MRS score was higher for HIV-positive compared to HIV-negative women (p = 0.01). Factors associated with severe menopause symptoms included HIV-positive status (aOR: 3.01, 95% CI: 1.20-7.54) and history of cigarette smoking (aOR: 4.18, 95% CI: 1.31-13.26). Being married (aOR: 0.49, 95% CI: 0.32-0.77), premenopausal (aOR: 0.60, 95% CI: 0.39-0.94), and self-reporting good quality of life (aOR: 0.62. 95% CI: 0.39-0.98) were protective against severe menopause symptoms. We found HIV infection, cigarette smoking, quality of life, and stage of the menopause transition to be associated with severe menopause symptoms. As HIV-positive populations are aging, additional attention should be given to the reproductive health of these women.

    We study the process theoretic notion of stuttering equivalence in the setting of parity games. We demonstrate that stuttering equivalent vertices have the same winner in the parity game. This means that solving a parity game can be accelerated by minimising the game graph with respect to stuttering

    Menopause usually occurs between the ages of 45 and 55, a time when women are likely to be in the paid workforce. Most women have menopausal symptoms and these may impact on daytime function and work performance. This study examines the relationship between reproductive stage, menopausal symptoms and work, and advises how employers can best support menopausal women. An online and paper-based survey was completed in 2015-16 by 1092 women (22% response rate) aged 40 years plus employed in three hospitals in metropolitan Australia. Survey questions examined demographics, health and lifestyle variables, menopausal symptom reporting, and work-related variables. Reproductive stage was determined using modified STRAW +10 principal and descriptive criteria. Reproductive stage was not significantly associated with work engagement, organizational commitment, job satisfaction, work limitations and perceived supervisor support. Postmenopausal women had lower intention to leave their organizations than pre- and peri-menopausal women. While sleep problems were the most commonly reported menopausal symptom by peri-menopausal women, for postmenopausal women it was joint and muscular discomfort. Only hot flushes and vaginal dryness were significantly more frequent in peri- and post, compared to pre-menopausal women. In general, women rated their work performance as high and did not feel that menopausal symptoms impaired their work ability. Most women would appreciate greater organizational support, specifically temperature control, flexible work hours and information about menopause for employees and managers. Most women did not believe that menopausal symptoms negatively impacted on their work. Organizational changes may reduce the burden of menopausal symptoms in the workplace.

    The symptoms and perceptions of menopause of 60 Australian women were studied, by questionnaire, when they were premenopausal and 10 years later when they were postmenopausal. Menopausal symptoms expected and experienced by the women were compared, fewer women experiencing hot flushes, headache, depression and nervousness and more experiencing insomnia, increase in appetite, abdominal fullness, numbness and muscular problems. The symptoms women thought were due to hormonal changes at menopause were compared. In 1993 more women cited osteoporosis, insomnia, loss of libido, obesity and loss of muscle tone as due to hormone change while fewer cited depression. The premenstrual symptoms and their severity experienced by a woman when she was premenopausal significantly predicts the type and severity of the menopausal symptoms experienced by the woman. The expected menopausal symptoms and their severity cited by a woman also significantly predicts the type of severity of the menopausal symptoms experienced. More premenstrual symptoms predict the menopausal symptoms than those menopausal symptoms the women expected. The expectation menopause will be 'a relief' or 'a nuisance' significantly predicted the overall menopause experience described by the women. Their negative attitudes about doctors' understanding and information available about menopause remained unchanged but they forget menstrual cycle problems over the 10 years. The results suggest a possible physiological basis for premenstrual and menopausal symptoms. Assistance for women with their premenstrual and menstrual cycle symptoms may improve their quality of life at menopause.

    Many postmenopausal women experience hot flashes, night sweats, non-specific emotional and psychological distresses. Our aim was to investigate the relation among steroid hormone levels, lipid profile and menopausal symptom severity using the menopause rating scale (MRS). A cross-sectional study was performed at our outpatient clinic with natural postmenopausal women. A total of 444 women were included in this study. The basic characteristics of the study population, such as age, gravidity, parity, time to menopause onset and body mass index (BMI) were recorded. Venous blood samples were collected from subjects after overnight fasting. The levels of high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, total cholesterol, triglyceride (TG), fasting plasma glucose, C-reactive protein, thyroid-stimulating hormone (TSH), cortisol, estradiol (E2), progesterone, testosterone and dehydroepiandrostenedione sulfate (DHEA-S) were analyzed. The MRS questionnaire validated for the Turkish population was used to assess the menopausal symptoms. There was a statistically significant difference between mild and severe total symptom scores for TG, and elevated TG levels were observed in the severe group (p = 0.04). Elevated testosterone levels were observed with severe psychological symptom and total symptom scores. There were significant differences in progesterone level in psychological, urogenital, and total scores and lower levels were seen in severe symptom groups. There was a significant negative correlation between urogenital symptom scores and progesterone levels (p symptom and total menopausal symptom scores. A decrease in progesterone levels was related to high psychological, urogenital and total menopausal symptom scores. Elevated TG levels were also related to the total severe symptom scores.

    The objective of this study was to examine the experience of menopause in postmenopausal women from Germany and in postmenopausal women from Papua New Guinea. Experience of menopause were assessed by formation of symptom groups (e. g. hot flushes, cardiac or sleeping trouble, depression, touchiness, drop in performance, vaginal dryness, painful joints or muscles), following the Menopause Rating Scale (MRS). Apart from the translated English version a questionaire in Pidgin English was offered. Questions about positive and negative experience of menopause and the acceptance of hormonal replacement therapy were included. Statistical analysis was performed both descriptively and for the group analyses the Chi-squared-test and the Mann Whitney's U test. 40 postmenopausal German women and 41 postmenopausal women from Papua New Guinea were asked about their experience of menopause. The German women were 58.7 years old (range from 52 to 62) and had two children on average (range from 0 to 4). 87.7 % had experience of symptoms. In Papua New Guinea mean age was 55.2 years (range from 48 to 70), parity six (range from 2 to 12). 76.9 % had experience of symptoms. There were significant intercultural differences between the experience of depressive mood, general drop of performance, sexual experience and the vaginal dryness and we found no significant intercultural differences between the experiences of hot flushes, cardiac trouble, sleeping trouble, nervousness and urological symptoms. 50 % of the German women take hormonal replacement therapy and nobody of Papua New Guinea. The experience of menopause as seen in the developed countries does not exist in the developing countries. The perception about illness and well-being are formed by culturally produced patterns.

    Given the complexity of the literature on quality of life (QOL) and hormone therapy (HT) among women in the menopausal transition and postmenopause, the purposes of this integrative review were to (1) define QOL as a multidimensional construct; (2) review validated instruments for measurement of QOL; (3) review results of HT and QOL clinical trials that have used validated instruments; and (4) assess the effectiveness of HT on QOL, including health-related QOL (HRQOL), menopause-specific QOL (MSQOL), and global QOL (GQOL). The literature on HT and QOL was searched for definitions of QOL and validated instruments for measuring QOL, and the results were summarized. The purposes of this integrative review were to evaluate the effects of HT on HRQOL, differentiating the effects of HT on GQOL, HRQOL, and MSQOL. As a basis for this review, we searched for published controlled clinical trials in which the effects of HT on QOL were studied using validated QOL instruments, in particular menopause-specific validated instruments. Clear definitions are elucidated. Validated instruments for the measurements of HRQOL, GQOL, and MSQOL are summarized, and the necessity of their incorporation into future research and clinical practice is emphasized. The published effects on QOL of estrogens and progestogens administered to symptomatic and nonsymptomatic women in the menopausal transition and beyond are reviewed. The impact of various health state-related symptoms on HRQOL and GQOL is now an integral component of contemporary health care. Effects of HT include GQOL and HRQOL and should be menopause-specific. There is clearly a need for further studies on menopause and menopause-related therapies using appropriate and validated instruments. Literature review shows that HT provides a significant benefit for MSQOL in midlife women, mainly through relief of symptoms, but treatment also may result in a global increase in sense of well-being (GQOL). HRQOL benefits are contingent on

    Polycystic ovary syndrome (PCOS), a common reproductive endocrine condition manifests at puberty, and is characterized by hyperandrogenism, chronic anovulation, and obesity. PCOS cases exhibit an adverse coronary heart disease (CHD) profile at an early age, including insulin resistance, dyslipidemia and increased central adiposity. It can be hypothesized that the menopausal transition, whether natural or surgical, may provide an additional "insult", resulting in greater cumulative risk to their vasculature. Coronary artery calcification (CAC), a measure of subclinical atherosclerosis (SCA), was measured by electron beam tomography in 149 PCOS cases and 166 controls (mean age 47.3 and 49.4 respectively). Cases had a higher prevalence of CAC (63.1%) compared to controls (41.0%), (p = 0.037) after adjustment for age and BMI. A total of 22 cases and 39 controls had undergone natural menopause, 12 cases and 26 controls underwent surgical menopause (with biochemical confirmation) and 115 cases and 101 controls reported being currently premenopausal. There was a significant difference in CAC values between cases and controls in all three-menopause categories including pre-menopausal, surgically induced and natural menopause (p 10) as the dependent variable, and independent variables: PCOS status, current age, BMI, and menopausal status, (pre-menopause, surgical and natural menopause) and selected CHD risk factors. The data indicate that women with PCOS exhibit significantly increased CAC compared to controls after adjustment for age and BMI and menopausal status. PCOS status and fasting glucose were significant risk factors for CAC (p PCOS status continues to affect cardiovascular risk as they undergo the menopausal transition.

    Left ventricular diastolic dysfunction (LVDD) has been relatively less studied than other cardiac changes during pregnancy. Previous studies revealed a mild diastolic deterioration during pregnancy. However, these studies did not evaluate the long-term effect of parity on left ventricular diastolic function. A comprehensive study evaluating the long-term effect of parity on diastolic function is required. A total of 710 women with various number of parity were evaluated through echocardiography to reveal the status of diastolic function. Echocardiographic parameters were compared among the women by parity number and categorized accordingly: none, 0 to 4 and 4 4 parity and that had 21 and 5.8 times higher than nulliparous group, respectively. In conclusion, according to the present study, grand multiparity but not multiparity, severely deteriorates left ventricular diastolic function. Further studies are warranted to evaluate the risk of gradual diastolic dysfunction after each pregnancy. Copyright © 2017 Elsevier Inc. All rights reserved.

    In recent years, growing importance has been afforded to assisting women in coping with the menopausal transition. Menopause is a normal stage of development and a woman's attitude toward this transition embodies biological, psychological and social influences. An enlarging body of conflicting data concerning menopausal hormone therapy (MHT) demands reassessment of established paradigms of disease prevention and menopausal health. Currently, a woman's decision to participate in or abstain from menopausal HT is personal. It involves not only consideration of risk stratification of potential harm and benefit, but also involves her expectations and attitudes toward perceived physical and emotional changes associated with this change. Through the use of extensive patient history, quality-of-life questionnaires and powerful biological profiling, we may be able to develop a rational approach to menopausal HT that safely guides our patients through this transition.

  10. The nondiscovery of parity nonconservation

    International Nuclear Information System (INIS)

    Franklin, A.

    1989-01-01

    Although experiments in 1928 and 1930 provided evidence for the nonconservation of parity in the weak interactions, it was not until weak interactions were needed in the 1950s to match experiment to theory that these were re-examined. After describing the two experiments and their results, the author concludes that while errors existed, the early works did show parity nonconservation, but their contemporaries in the scientific community rejected their evidence, partly because the theoretical framework to explain it did not yet exist. High energy electron beams meant that experiments reproducing earlier work on beta decay were unlikely to be repeated and because the difference between thermion, C and decay electrons was not then understood.

Consuming the high risk-adjusted returns of safer assets requires leverage, creating an opportunity for investors with the ability...... to apply leverage. Risk parity portfolios exploit this opportunity by equalizing the risk allocation across asset classes, thus overweighting safer assets relative to their weight in the market portfolio....

    The elaboration of the electroweak standard model from the discovery of parity violation to the weak neutral current is described in the first chapter. In the second chapter the author discusses the 2 experimental approaches of the parity violation experiments. In the first approach the weak neutral current can be assumed to be well known and can be used as a probe for the hadronic matter. The second approach consists in measuring the weak neutral current between 2 particles with known internal structure in order to test the predictions of the standard model in the low energy range. The chapters 3 and 4 are an illustration of the first approach through the HAPPEx series of experiments that took place in the Jefferson Laboratory from 1998 to 2005. The HAPPEx experiments aimed at measuring the contribution of strange quarks in the electromagnetic form factors of the nucleon through the violation of parity in the elastic scattering at forward angles. The last chapter is dedicated to the E158 experiment that was performed at the Slac (California) between 2000 and 2003. The weak neutral current was measured between 2 electrons and the high accuracy obtained allowed the physics beyond the standard model to be indirectly constraint up to a few TeV. (A.C.)

    The relationship between parity and life span is uncertain, with evidence of both positive and negative relationships being reported previously. We evaluated this issue by using genealogical data from an Old Order Amish community in Lancaster, Pennsylvania, a population characterized by large nuclear families, homogeneous lifestyle, and extensive genealogical records. The analysis was restricted to the set of 2,015 individuals who had children, were born between 1749 and 1912, and survived until at least age 50 years. Pedigree structures and birth and death dates were extracted from Amish genealogies, and the relationship between parity and longevity was examined using a variance component framework. Life span of fathers increased in linear fashion with increasing number of children (0.23 years per additional child; p =.01), while life span of mothers increased linearly up to 14 children (0.32 years per additional child; p =.004) but decreased with each additional child beyond 14 (p =.0004). Among women, but not men, a later age at last birth was associated with longer life span (p =.001). Adjusting for age at last birth obliterated the correlation between maternal life span and number of children, except among mothers with ultrahigh (>14 children) parity. We conclude that high parity among men and later menopause among women may be markers for increased life span. Understanding the biological and/or social factors mediating these relationships may provide insights into mechanisms underlying successful aging.

    To describe changes in the characteristics of women's menstrual cycles during the menopause transition and to identify whether such changes are perceived by women as being problematic. A cross-sectional descriptive study using a community-based convenience sample of 119 women aged 37-70 years. Participants completed a questionnaire to obtain data on demographic characteristics, menopausal status and changes to menstrual flow, duration, frequency and regularity. There was a common pattern of menstrual change which was of heavier, less frequent, irregular menstruation. Forty one percent of post-menopausal and 40% of women still in the menopause transition stated that, in terms of overall perception, the changes to menstruation experienced during the menopause transition were not problematic or disruptive. When specific change characteristics were examined, significant differences were found in duration of menses (p=0.014) and cycle irregularity (p=0.005) but no significant differences were found on the amount of flow (p=0.125) or frequency of cycles (p=0.142). Increased duration and increased irregularity of occurrence of each period are problematic for women going through the menopause transition, however, increased amount of menstrual flow at each period and increased frequency of cycles are not problematic changes.

    Full Text Available The parity-preserving massive QED3 exhibits vanishing gauge coupling β-function and is parity and infrared anomaly free at all orders in perturbation theory. Parity is not an anomalous symmetry, even for the parity-preserving massive QED3, in spite of some claims about the possibility of a perturbative parity breakdown, called parity anomaly. The proof is done by using the algebraic renormalization method, which is independent of any regularization scheme, based on general theorems of perturbative quantum field theory.

    This study explored women's experiences of working through menopausal transition in the UK. It aimed to identify the perceived effects of menopausal symptoms on working life, to outline the perceived effects of work on menopausal symptoms, and to provide recommendations for women, healthcare practitioners and employers. An electronic questionnaire was distributed to women aged 45-55 in professional, managerial and administrative (non-manual) occupations in 10 organisations. Items included: age, age and gender of line manager, educational level, job satisfaction; menopausal status; symptoms that were problematic for work; hot flushes; working conditions; work performance, disclosure to line managers; individual coping strategies; and, effective workplace adjustments and employer support. The final sample comprised 896 women. Menopausal transition caused difficulties for some women at work. The most problematic symptoms were: poor concentration, tiredness, poor memory, feeling low/depressed and lowered confidence. Hot flushes were particularly difficult. Some women felt work performance had been negatively affected. The majority of women were unwilling to disclose menopause-related health problems to line managers, most of whom were men or younger than them. Individual coping strategies were described. Four major areas for organisational-level support emerged: (i) greater awareness among managers about menopause as a possible occupational health issue, (ii) flexible working hours, (iii) access to information and sources of support at work, and (iv) attention to workplace temperature and ventilation. Employers and healthcare practitioners should be aware that menopausal transition causes difficulty for some women at work, and that much can be done to support them.

    Full Text Available Background: Menopause is a physiological event that occurs in women's life and result in physical, emotional and social changes which affects their quality of life. Because of controversial finding in previous researches and lack of such study in kashan city, this study investigated the quality of life in menopausal women and its related factors. Methods: A cross - sectional study was performed on 700 menopausal women aged 40-60 in Kashan city with cluster sampling. Menopausal Specific Quality of life questionnaire (MENQOL was used for estimation of QOL and related factor such as age, job, educational level, marital status, duration of menopause, child at home, income satisfaction, marital satisfaction, exercise, smoking and family smoking were examined with statistical tests. Results: The quality of life was high in 17.9%, intermediate in 68.9% and low in 13.3% of women. Most of women had intermediate quality of life at vasomotor domain (67.3 %, psychosomatic domain (67.4%, physical domain(46.3% and sexual domain (51.6%.Also there was a significant difference between quality of life and educational level (P=0.004, income satisfaction (P=0.01 and exercise (P=0.0001. Conclusions: Educational level, exercise and income satisfaction are related with quality of life in menopausal women. Based on our findings, we emphasis on teaching about menopause, its symptom and adverse effects. Also emphasizes the necessity use of non pharmacological methods such as exercise and change in life style and diet to improve quality of life in menopausal women.

Elderly people are expected to grow rapidly than other groups. The fastest increase in the elderly population will take place in Asia. Life expectancy is increasing steadily throughout developed and developing countries. For many  menopausal women, increased life expectancy will accompanied by many health problems. The consequences of estrogen deficiency are the menopausal symptoms. The treatment of menopause related complaints and diseases became an  important socioeconomic and medical issue. Long term symptoms, such as the increase in osteoporosis fractures, cardio and cerebrovascular disesses and dementia, created a large financial burden on individuals and society.

  7. Non-planar ABJ theory and parity

    While the ABJ Chern-Simons-matter theory and its string theory dual manifestly lack parity invariance, no sign of parity violation has so far been observed on the weak coupling spin chain side. In particular, the planar two-loop dilatation generator of ABJ theory is parity invariant. In this Letter we derive the non-planar part of the two-loop dilatation generator of ABJ theory in its SU(2)xSU(2) sub-sector. Applying the dilatation generator to short operators, we explicitly demonstrate that, for operators carrying excitations on both spin chains, the non-planar part breaks parity invariance. For operators with only one type of excitation, however, parity remains conserved at the non-planar level. We furthermore observe that, as for ABJM theory, the degeneracy between planar parity pairs is lifted when non-planar corrections are taken into account.

    2010-01-01

    The problem of solving a parity game is at the core of many problems in model checking, satisfiability checking and program synthesis. Some of the best algorithms for solving parity game are strategy improvement algorithms. These are global in nature since they require the entire parity game to be present at the beginning. This is a distinct disadvantage because in many applications one only needs to know which winning region a particular node belongs to, and a witnessing winning strategy may...

    Theoretical and phenomenological approaches to parity-non-conserving nuclear forces are reviewed. Recent developments in the calculation of weak meson-nucleon coupling constants, whose knowledge is necessary to determine theoretically the parity-non-conserving nucleon-nucleon potential, are described. The consistency of different measurements of parity-non-conserving effects is discussed and the information they provide is compared to theoretical predictions

    Chavez, H.; Martins Simoes, J.A.

    2007-01-01

    In this paper we present a model for the spontaneous breaking of parity with two Higgs doublets and two neutral Higgs singlets which are even and odd under D-parity. The condition υ R >>υ L can be satisfied without introducing bidoublets, and it is induced by the breaking of D-parity through the vacuum expectation value of the odd Higgs singlet. Examples of left-right symmetric and mirror fermions models in grand unified theories are presented. (orig.)

    The exact parity model (EPM) is a simple extension of the standard model which reinstates parity invariance as an unbroken symmetry of nature. The mirror matter sector of the model can interact with ordinary matter through gauge boson mixing, Higgs boson mixing and, if neutrinos are massive, through neutrino mixing. The last effect has experimental support through the observed solar and atmospheric neutrino anomalies. In the paper it is shown that the exact parity model can be formulated in a quaternionic framework. This suggests that the idea of mirror matter and exact parity may have profound implications for the mathematical formulation of quantum theory. 13 refs.

    Full Text Available PURPOSE: Pre-menopausal women with cancer are at risk of therapy-associated infertility, premature menopause, and sexual dysfunction. However, it is unknown whether oncologists adequately address these risks during treatment planning. We conducted a study to evaluate physician-patient discussions addressing the impact of cancer treatment and actual treatment effects on fertility, menopause status, and general sexual health.METHODS: A questionnaire was administered in four oncology clinics specializing in breast, gynecologic, general hematology-oncology, and blood and marrow transplantation (BMT cancer care at a single institution. Eligible participants were pre-menopausal at the time of diagnosis and either actively receiving or within 24 months from completion of treatment. Participants completed the questionnaire at enrollment and at 1-year follow-up.RESULTS: Of the 104 eligible women, a majority were satisfied with the quality (68% and length (66% of reproductive health discussions, with the highest satisfaction levels in the gynecologic cancer clinic (85% and the lowest levels in the BMT clinic (53%. Fertility preservation was desired by 20% of women, including some >40 years old. Women were more interested in discussing treatment impact on menopause status and sexual health than fertility. Rates of discussions on treatment impact on sexual health were low despite 77% of women reporting severe sexual dysfunction at 1-year follow-up.CONCLUSIONS: One-third of women are dissatisfied with the quality and length of discussions regarding the impact of cancer treatment on reproductive health. There is notably inadequate counseling on the effect of treatment on fertility in women > 40 and on sexual function in all women. Oncologists must offer better resources and improve communication on the effect of treatment on reproductive health to pre-menopausal women with cancer.

  16. Working women and the menopause.

    Science.gov (United States)

    2015-06-01

    Women are living longer, working more and retiring later. About 45% of the over 50-year-old workforce in virtually all forms of employment are women, all of whom will experience the menopause and its symptoms, which in some women will be mild to moderate, whilst in others they may be severe and debilitating. About half of these women will find it somewhat, or fairly difficult, to cope with their work, about half will not be affected and only about 5% will be severely compromised. Poor concentration, tiredness, poor memory, depression, feeling low, lowered confidence, sleepiness and particularly hot flushes are all cited as contributing factors. As with any longstanding health-related condition, the need for support and understanding from line management is crucial and can make a major difference to how a woman will deal with the adverse impact the menopausal symptoms may have on her productivity, her job satisfaction and her efficiency. A number of plausible strategies have been proposed that can be realistically implemented in the workplace and which could certainly make a significant difference. Careful thought, planning, consideration and effort may be required but, if instituted, they will, in the final analysis, benefit both employer and employee.

    Full Text Available Taking into account that climacteric constitutes a physiological state in woman’s life, which covers a large stage of her life cycle, it is important that nursery professionals will develop an Action Plan, whose main objective will be health. Covering, then, this stage from a multidisciplinary and holistic field is going to contribute to both: the adoption of healthy life habits and the repercussions that symptoms and physiological processes associated with menopause have on women. Another objective for nurses there must be to provide all our knowledge in a detailed and focused on the individual needs that may come up way. That way, we lay the foundations for facing climacteric with the minimum deterioration of the quality of life and well being.This article is an analysis of the etiology of every one of the most prevalent menopause problems, the predisposing factors to suffer them or to make them get worse, and the habits that are going to prevent larger spill-over effects of those problems. Furthermore, a revision about how nutrition, exercise, toxic substances consumption, etc. have repercussions on musculoskeletal problems, vascular symptoms, urogenital problems, psychological alterations, and gynaecological and breast cancer is made.

    There are limited empirical data to support the theory of a protective effect of parenthood against suicide, as proposed by Durkheim in 1897. I conducted this study to examine whether there is an association between parity and risk of death from suicide among women. The study cohort consisted of 1,292,462 women in Taiwan who had a first live birth between Jan. 1, 1978, and Dec. 31, 1987. The women were followed up from the date of their first birth to Dec. 31, 2007. Their vital status was ascertained by means of linking records with data from a computerized mortality database. Cox proportional hazard regression models were used to estimate hazard ratios of death from suicide associated with parity. There were 2252 deaths from suicide during 32 464 187 person-years of follow-up. Suicide-related mortality was 6.94 per 100,000 person-years. After adjustment for age at first birth, marital status, years of schooling and place of delivery, the adjusted hazard ratio was 0.61 (95% confidence interval [CI] 0.54-0.68) among women with two live births and 0.40 (95% CI 0.35-0.45) among those with three or more live births, compared with women who had one live birth. I observed a significantly decreasing trend in adjusted hazard ratios of suicide with increasing parity. This study provides evidence to support Durkheim's hypothesis that parenthood confers a protective effect against suicide.

    To examine the association between self-prescribed complementary and alternative medicine use and menopause-related symptoms, stratified by menopausal status. Data were obtained from a cross-sectional survey of a nationally representative sample of 10,011 menopausal women from the Australian Longitudinal Study on Women's Health, conducted in 2010. Multivariable logistic regression models were applied to identify if the use of selected self-prescribed complementary and alternative medicine was significantly associated with a range of menopause-related symptoms. Vitamins/minerals were more likely to be used by natural menopausal women experiencing anxiety (adjusted OR=1.20) and/or stiff/painful joints (adjusted OR=1.16). Yoga/meditation was more likely to be used by women with hysterectomy (adjusted OR=1.76) or natural menopausal women (adjusted OR=1.38) experiencing anxiety. Herbal medicines were more likely to be used by natural menopausal women experiencing anxiety (adjusted OR=1.22), tiredness (adjusted OR=1.20), and/or stiff/painful joints (adjusted OR=1.17), and by women with oophorectomy experiencing tiredness (adjusted OR=1.45). Aromatherapy oils were more likely to be used by natural menopausal women experiencing night sweats (adjusted OR=1.25) and by women with hysterectomy experiencing anxiety (adjusted OR=2.02). Chinese medicines were more likely to be used by women with oophorectomy experiencing stiff/painful joints (adjusted OR=4.06) and/or palpitations (adjusted OR=3.06). Our study will help improve the patient-provider communication regarding complementary and alternative medicine use for menopause, and we conclude that menopausal status should be taken into account by providers for menopause care. The women's experience and motivations of such use warrant further research. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2018-01-17

    The establishment of non-Hermitian quantum mechanics (such as parity-time (PT) symmetry) stimulates a paradigmatic shift for studying symmetries of complex potentials. Owing to the convenient manipulation of optical gain and loss in analogy to the complex quantum potentials, photonics provides an ideal platform for visualization of many conceptually striking predictions from the non-Hermitian quantum theory. A rapidly developing field has emerged, namely, PT symmetric photonics, demonstrating intriguing optical phenomena including eigenstate coalescence and spontaneous PT symmetry breaking. The advance of quantum physics, as the feedback, provides photonics with brand-new paradigms to explore the entire complex permittivity plane for novel optical functionalities. Here, we review recent exciting breakthroughs in PT symmetric photonics while systematically presenting their underlying principles guided by non-Hermitian symmetries. The potential device applications for optical communication and computing, bio-chemical sensing, and healthcare are also discussed.

    1993-02-01

    A status report is given of a parity-invariant model of two-dimensional superconductivity. The model consists of two-species of fermions coupled with opposite sign to an Abelian gauge field and is closely related to QED 3 . The dynamical generation of a parity-conserving fermion mass and the finite temperature symmetry restoration transition is studied, and it is shown, how the parity-invariant model arises as an effective long-wavelength theory of the dynamics of holes in a two-dimensional quantum antiferromagnetic system on a bi-partite lattice. The model exhibits type-II superconductivity without parity or time-reversal symmetry violation, a high value of 2 Δ /k B T c , flux quantization with quantum hc/2e and a two-dimensional Meissner effect.

    The Weinberg-Salam Unified Model of weak and electromagnetic interactions has been very successful in explaining parity violation and neutral current effects in neutrino-nucleon, electron-nucleon and neutrino-electron interactions. A wide variety of nuclear physics parity violation experiments are in progress to measure effects of the weak nucleon-nucleon interaction in few nucleon systems and certain heavier nuclei where enhancements are expected. The current status of these experiments will be reviewed, including details of an experiment at Chalk River to search for parity violation in the photodisintegration of deuterium and an extension of our previous measurements of parity mixing in 21 Ne. The interpretation of results in terms of basic models of the weak interaction will be discussed. (Auth)

    Introduction Some studies have investigated the influence of hormonal deficits and menopausal status in muscle disorders of women. However, it has not been investigated the relationship of both climacteric symptoms and the perception of quality of life with physical performance. Objective To evaluate the correlation of menopausal symptoms and quality of life with physical performance in middle-aged women. Methods This cross-sectional study was performed from April to November 2013 in the municipality of Parnamirim, in the Brazilian state, Rio Grande do Norte. The sample was composed of 497 women aged 40-65 years. The Menopause Rating Scale (MRS) and the Utian Quality of Life (UQOL) questionnaire were used to evaluate menopausal symptoms and quality of life respectively. Measures of physical performance included handgrip strength, knee extensor and flexor strengths (using an isometric dynamometer), gait speed, and chair stand test. The correlation between menopausal symptoms and quality of life with physical performance was assessed by Pearson's correlation coefficient with significance set at p correlation between handgrip strength and somatic MRS score (p = 0.002) and total MRS score (p = 0.03). There was a significant correlation between knee flexor strength and sit-to-stand time and all menopausal symptom areas (p correlation between physical performance of the knee flexors and quality of life items including occupational (p = 0.001), emotional (p = 0.005), and total UQOL (p = 0.01), but a negative correlation with sit-to-stand time and all quality of life domains (p < 0.05). Conclusion A greater intensity of menopausal symptoms and worse quality of life were related with worse physical performance. Thus, preventive measures should be implemented to avoid adverse effects on physical performance at more advanced ages. Thieme Publicações Ltda Rio de Janeiro, Brazil.

  15. The emergence of the menopause in India.

    Sengupta, A

    2003-06-01

    A total of 130 million Indian women are expected to live beyond the menopause into old age by 2015. The menopause is emerging as an issue owing to rapid globalization, urbanization, awareness and increased longevity in urban middle-aged Indian women, who are evolving as a homogeneous group. Improved economic conditions and education may cause the attitude of rural working women to be more positive towards the menopause. However, most remain oblivious of the short- and long-term implications of the morbid conditions associated with middle and old age, simply because of lack of awareness, and the unavailability or ever-increasing cost of the medical and social support systems. Evidence-based medicine is accessible to still only a few Indian women. Most menopausal women go untreated or use unproven alternative therapies.

    2001-01-01

    Women's health providers, especially midwives, must take into account the known benefits and risks, as well as the "unknown," when recommending the use of hormone therapy for menopausal women, especially as it relates to heart disease, breast cancer, impaired cognition, and osteoporosis. The most recent evidence available from various studies about the benefits and risks of estrogen and hormone therapy at menopause suggests that, although hormone therapy may be protective in some women against heart disease and osteoporosis, evidence is less certain about the benefits of hormone protection against impaired cognition and the risks of breast cancer with use. The clinical approach used by midwives in which individualizing care based on each woman's health status history as well as preferences is highly appropriate for women in the perimenopausal and menopausal period.

    The aim of this study was to investigate the relationship between menopause and self-reported sleep quality in Chinese women without vasomotor symptoms. Cross-sectional data were collected from a decoded database of the National Cheng Kung University Hospital. Menopause was defined as absence of menses for at least 12 months or a history of hysterectomy and oophorectomy. Self-reported sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A higher global PSQI score indicates poorer self-reported sleep quality, and a global PSQI score greater than 5 differentiates poor sleepers from good sleepers. Of the 1,088 women recruited, 353 (32.4%) were in postmenopause status. Postmenopausal women had higher mean (SD) global PSQI scores (8.0 [3.3] vs. 6.1 [2.2], P menopause (β = 1.532; 95% CI, 1.135 to 1.949; P menopause (odds ratio, 1.453; 95% CI, 1.030 to 2.051; P menopause and snoring are associated with an increased risk of poor self-reported sleep quality independently of cardiometabolic factors and lifestyle, whereas long sleep duration is associated with a decreased risk of poor self-reported sleep quality.

    We investigate the phenomenology of the MSSM extended by a single R-parity-violating coupling at the unification scale. For all R-parity-violating couplings, we discuss the evolution of the particle spectra through the renormalization group equations and the nature of the lightest supersymmetric particle (LSP) within the CMSSM, as an example of a specific complete supersymmetric model. We use the nature of the LSP to classify the possible signatures. For each possible scenario we present in detail the current LHC bounds on the supersymmetric particle masses, typically obtained using simplified models. From this we determine the present coverage of R-parity-violating models at the LHC. We find several gaps, in particular for a stau-LSP, which is easily obtained in R-parity-violating models. Using the program CheckMATE we recast existing LHC searches to set limits on the parameters of all R-parity-violating CMSSMs. We find that virtually all of them are either more strongly constrained or similarly constrained in comparison to the R-parity-conserving CMSSM, including the anti U anti D anti D models. For each R-parity-violating CMSSM we then give the explicit lower mass bounds on all relevant supersymmetric particles. (orig.)

    The presence of R-parity violating interactions may relieve the tension between existing LHC constraints and natural supersymmetry. In this paper we lay down the theoretical framework and explore models of dynamical R-parity violation in which the breaking of R-parity is communicated to the visible sector by heavy messenger fields. We find that R-parity violation is often dominated by non-holomorphic operators that have so far been largely ignored, and might require a modification of the existing searches at the LHC. The dynamical origin implies that the effects of such operators are suppressed by the ratio of either the light fermion masses or the supersymmetry breaking scale to the mediation scale, thereby providing a natural explanation for the smallness of R-parity violation. We consider various scenarios, classified by whether R-parity violation, flavor breaking and/or supersymmetry breaking are mediated by the same messenger fields. The most compact case, corresponding to a deformation of the so called flavor mediation scenario, allows for the mediation of supersymmetry breaking, R-parity breaking, and flavor symmetry breaking in a unified manner.

    This study aims to explore the effects of menopause and hormone therapy on the symptoms and signs of stress urinary incontinence and urge urinary incontinence. Records of women who attended a tertiary urogynecological unit were reviewed retrospectively. A standardized interview included evaluations of symptoms, menopause age (ie, time since last menstrual period or onset of menopausal symptoms), current or previous hormone use, and visual analogue scales for bother. Multichannel urodynamics, including urethral pressure profilometry and determination of abdominal leak point pressure, was performed. Of 382 women seen during the inclusion period, 62% were postmenopausal. Current systemic or local hormone use was reported by 7% and 6%, respectively. Two hundred eighty-eight women (76%) reported symptoms of stress urinary incontinence, with a mean bother of 5.7, and 273 women (72%) reported symptoms of urge urinary incontinence, with a mean bother of 6.4. On univariate analysis, symptoms and bother of urge incontinence were significantly related to menopause age, whereas this relationship was not found for stress incontinence. After calendar age was controlled for, length of menopause showed no significant relationship with any symptom or sign of urinary incontinence. Hormone deficiency after menopause is unlikely to play a major role in urinary incontinence.

    A woman’s age at menarche (first menstrual period) and her age at menopause are the alpha and omega of her reproductive years. The timing of these milestones is critical for a woman’s health trajectory over her lifespan, as they are indicators of ovarian function and aging. Both early and late timing of either event are associated with risk for adverse health and psychosocial outcomes. Thus, the search for a relationship between age at menarche and menopause has consequences for chronic disease prevention and implications for public health. This article is a review of evidence from the fields of developmental biology, epidemiology, nutrition, demography, sociology, and psychology that examine the menarche–menopause connection. Trends in ages at menarche and menopause worldwide and in subpopulations are presented; however, challenges exist in constructing trends. Among 36 studies that examine the association between the two sentinel events, ten reported a significant direct association, two an inverse association, and the remainder had null findings. Multiple factors, including hormonal and environmental exposures, socioeconomic status, and stress throughout the life course are hypothesized to influence the tempo of growth, including body size and height, development, menarche, menopause, and the aging process in women. The complexity of these factors and the pathways related to their effects on each sentinel event complicate evaluation of the relationship between menarche and menopause. Limitations of past investigations are discussed, including lack of comparability of socioeconomic status indicators and biomarker use across studies, while minority group differences have received scant attention. Suggestions for future directions are proposed. As research across endocrinology, epidemiology, and the social sciences becomes more integrated, the confluence of perspectives will yield a richer understanding of the influences on the tempo of a woman

    We present a consistent color-flavor-spin-orbital wave function for a positive-parity Θ + that naturally explains the observed narrowness of the state. The wave function is totally symmetric in its flavor-spin part and totally antisymmetric in its color-orbital part. If flavor-spin interactions dominate, this wave function renders the positive-parity Θ + lighter than its negative-parity counterpart. We consider decays of the Θ + and compute the overlap of this state with the kinematically allowed final states. Our results are numerically small. We note that dynamical correlations between quarks are not necessary to obtain narrow pentaquark widths

    The cost of photovoltaic systems is decreasing and the price of electrical power is increasing, so at one moment the 2 curves will meet and at that moment there will be grid parity, it means that the photovoltaic power will be as competitive as other energies and will need no more subsidies. In Denmark the electricity is so expensive that the grid parity has already been reached and photovoltaic power is developing there on the basis of net metering. According to the EPIA (European Association for Photovoltaic Industry), France, Germany, Italy, Spain and United-Kingdom will reach grid parity by 2020. (A.C.)

    The structure of the unnatural parity states of PsH, LiPs, NaPs, and KPs are investigated with the configuration interaction and stochastic variational methods. The binding energies (in hartree) are found to be 8.17x10 -4 , 4.42x10 -4 , 15.14x10 -4 , and 21.80x10 -4 , respectively. These states are constructed by first coupling the two electrons into a configuration which is predominantly 3 P e , and then adding a p-wave positron. All the active particles are in states in which the relative angular momentum between any pair of particles is at least L=1. The LiPs state is Borromean since there are no three-body bound subsystems (of the correct symmetry) of the (Li + , e - , e - , e + ) particles that make up the system. The dominant decay mode of these states will be radiative decay into a configuration that autoionizes or undergoes positron annihilation

    The aim of this study was to investigate the perception and experience of menopause diagnosis and therapies, the information provided and health behaviors in younger women with breast cancer. The questionnaire study was completed by 114 women, aged 40-51 years, with non-metastatic breast cancer. Women were recruited from outpatient clinics and the community. Descriptive statistics were completed. Most women were satisfied with the manner in which they were informed of the breast cancer (69%) and the menopause (59%) diagnoses. Although 80% of women were given breast cancer information, only 54% were given menopause information at diagnosis. Women were least satisfied (26%) with information regarding the long-term complications of menopause. Women perceived exercise (68%) and improving lifestyle (61%) as most effective in alleviating symptoms of menopause. The majority of women reported that they did not understand the risks/benefits of 'bioidentical' hormones (79%) and herbal therapies (78%), while 58% perceived hormone replacement therapies as associated with an increased risk of breast cancer. Most women reported weight gain (68%) and osteoporosis (67%) as the most common problems/fears regarding menopause. However, regarding health behaviors, only 56% reported having relevant tests including a blood sugar test or a bone density test. While information needs regarding breast cancer appear well met in younger women, unmet information needs regarding menopause after breast cancer persist. Further education and support are required for these women to optimize health screening and prevention behaviors and to ensure informed decision-making regarding menopause treatment options.

    We aimed to determine whether grand multiparity is a risk factor for osteoporosis among postmenopausal women of lower socioeconomic status. We conducted a single center study between February 2012 and February 2013 on 50-60 year old postmenopausal women of lower socioeconomic status without a history of medical disease. Women with a body mass index (BMI) between 20 and 25 were included in the study. The grand multiparous group (group A) consisted of 38 women with 10 or more deliveries. Women with a history of three or fewer deliveries composed the control group (group B). Dual-energy x-ray absorptiometry was used to measure the bone mineral density (BMD) of the proximal femur neck and lumbar spine (L1-L4). The mean ages of groups A and B were found to be 54.3 ± 2.5 and 53.1 ± 2.7 years, respectively. Average parity in groups A and B was 11.1 ± 1.7 and 2.4 ± 0.7, respectively. Time since the onset of menopause was 3.6 ± 2.7 years in group A and 6.0 ± 2.9 in group B. The prevalence of osteoporosis was similar in both groups (71.1%-81.4%, p = 0.273). We found that grand multiparity was an ineffective indicator of either femoral or lumbar osteoporosis (p = 0.87 and p = 0.26), but osteoporosis five years after the onset of menopause was found to be significantly higher (p = 0.02). The duration of menopause is an independent risk factor of osteoporosis. However, the number of pregnancies is neither a determinant nor a protective factor for osteoporosis in postmenopausal women coming from a low socioeconomic background.

    Objective To examine the associations of reproductive factors and exogenous hormone use with risk of Parkinson’s disease (PD) among postmenopausal women. Methods The study comprised 119,166 postmenopausal women ages 50–71 years in the NIH-AARP Diet and Health Study, who completed a baseline questionnaire in 1995–1996 and a follow-up survey in 2004–2006. A total of 410 self-reported PD diagnoses were identified between 1995 and 2006. Multivariate odds ratios (OR) and 95% confidence intervals (CI) were derived from logistic regression models. Results PD risk was not significantly associated with female reproductive factors including age at menarche, age at first live birth, parity, and age at menopause. For example, compared with women with natural menopause at ages 50–54 years, the ORs were 1.18, (95% CI 0.78–1.79) for women with natural menopause at ages <45, 1.19 (0.88–1.61) for ages 45–49, and 1.33 (0.91–1.93) for ages 55 or later. We found that oral contraceptive use for ≥10 years (vs. never use) was associated with lower PD risk (OR=0.59; 0.38–0.92) but shorter use showed no association. Use of menopausal hormone therapy showed inconsistent results. Compared with non-hormone users at baseline, current hormone users of <5 years showed a higher risk of PD (OR=1.52; 1.11–2.08). However, no associations were observed for past hormone users or current users of ≥5 years. Conclusions Overall, this large prospective study provides little support for an association between female reproductive factors and PD risk. Our findings on long-term oral contraceptive use and current hormone therapy warrant further investigations. PMID:24352877

    We present a complete classification of the vacuum geometries of all renormalizable superpotentials built from the fields of the electroweak sector of the MSSM. In addition to the Severi and affine Calabi-Yau varieties previously found, new vacuum manifolds are identified; we thereby investigate the geometrical implication of theories which display a manifest matter parity (or R-parity) via the distinction between leptonic and Higgs doublets, and of the lepton number assignment of the right-handed neutrino fields. We find that the traditional R-parity assignments of the MSSM more readily accommodate the neutrino see-saw mechanism with non-trivial geometry than those superpotentials that violate R-parity. However there appears to be no geometrical preference for a fundamental Higgs bilinear in the superpotential, with operators that violate lepton number, such as νHH̄, generating vacuum moduli spaces equivalent to those with a fundamental bilinear.

  13. Local Strategy Improvement for Parity Game Solving

    Oliver Friedmann

    2010-06-01

    Full Text Available The problem of solving a parity game is at the core of many problems in model checking, satisfiability checking and program synthesis. Some of the best algorithms for solving parity game are strategy improvement algorithms. These are global in nature since they require the entire parity game to be present at the beginning. This is a distinct disadvantage because in many applications one only needs to know which winning region a particular node belongs to, and a witnessing winning strategy may cover only a fractional part of the entire game graph. We present a local strategy improvement algorithm which explores the game graph on-the-fly whilst performing the improvement steps. We also compare it empirically with existing global strategy improvement algorithms and the currently only other local algorithm for solving parity games. It turns out that local strategy improvement can outperform these others by several orders of magnitude.

    The purpose of the present study was to examine the relationships of multiple factors to menopausal symptoms in different racial/ethnic groups of midlife women. This secondary analysis was conducted with the data from 980 midlife women that were collected from 2005 to 2013 using the Midlife Women's Symptom Index. Structural equation modeling was used to analyze the data. The model had the highest fit indices for Non-Hispanic (NH) White midlife women, and prominent racial/ethnic differences were observed in the relationships of multiple factors to menopausal symptoms. In all racial/ethnic groups (except in Hispanic women), perceived health status was significantly associated positively with menopausal symptoms (β = -0.149 for NH African American; β = -0.207 for NH Asians; β = -0.162 for NH Whites). Body mass index was significantly positively associated with menopausal symptoms only in NH Asians (β = 0.118) and Hispanics (β = 0.210). The racial/ethnic differences in the relationships of multiple factors to menopausal symptoms could have resulted from the different cultural contexts in which women undergo during their menopausal transitions. Further cultural studies on the associations of racial/ethnic-specific factors with menopausal symptoms would help in understanding possible causes for racial/ethnic differences in the factors significantly associated with menopausal symptoms.

    Full Text Available OBJECTIVE: To evaluate mammographic breast density in asymptomatic menopausal women in correlation with clinical and sonographic findings. MATERIALS AND METHODS: Mammograms and clinical and sonographic findings of 238 asymptomatic patients were retrospectively reviewed in the period from February/2022 to June/2006. The following variables were analyzed: mammographic density patterns, sonographic findings, patients' age, parity, body mass index and use of hormone replacement therapy. RESULTS: Age, parity and body mass index showed a negative correlation with breast density pattern, while use of hormone replacement therapy showed a positive correlation. Supplementary breast ultrasonography was performed in 103 (43.2% patients. Alterations which could not be visualized at mammography were found in 34 (33% of them, most frequently in women with breast density patterns 3 and 4. CONCLUSION: The authors concluded that breast density patterns were influenced by age, parity, body mass index and time of hormone replacement therapy. Despite not having found any malignant abnormality in the studied cases, the authors have observed a predominance of benign sonographic abnormalities in women with high breast density patterns and without mammographic abnormalities, proving the relevance of supplementary ultrasonography to identify breast lesions in such patients.

  17. Muscle performance after the menopause.

    2005-06-01

    The timing of the menopause transition has remained fairly constant throughout history. It represents a milestone in female health and, after passing through it, women experience increased musculoskeletal and cardiovascular morbidity. Muscle performance is an important determinant of functional capacity and quality of life among the elderly and is also involved in the maintenance of balance. Therefore, good muscle strength can prevent fragility fractures and lessen the burden of osteoporosis. Muscle strength begins to decline during the perimenopausal years and this phenomenon seems to be partly estrogen dependent. Randomized controlled trials have indicated that hormone replacement therapy may prevent a decline in muscle performance, although the exact mechanism of estrogen-dependent sarcopenia remains to be clarified. Exercises have been shown to improve postmenopausal muscle performance and hormone replacement therapy may also potentiate these beneficial effects. Improvement or maintenance of muscle strength alone, however, may not be considered as a primary indication for long-term hormone replacement therapy in view of current knowledge of its risks and benefits. Work history and educational background may be associated with postmenopausal muscle performance, which itself has unique associations with skeletal and cardiovascular diseases.

    Full Text Available Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS, which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder.

    It is known that realistic neutrino masses for neutrino oscillations may be obtained from R parity nonconserving supersymmetry. It is also known that such interactions would erase any preexisting lepton or baryon asymmetry of the Universe because of the inevitable intervention of the electroweak sphalerons. It is showed how a crucial subset of these R parity nonconserving terms may in fact create its own successful leptogenesis.

    Little Higgs models are an interesting extension of the standard model at the TeV scale. They provide a simple and attractive mechanism of electroweak symmetry breaking. We review one of the simplest models of this class, the littlest Higgs model, and its extension with T parity. The model with T parity satisfies precision electroweak constraints without fine-tuning, contains an attractive dark matter candidate, and leads to interesting phenomenology at the Large Hadron Collider (LHC).

    2010-06-01

    Parity, the idea that insurance coverage for the treatment of addiction should be on a par with insurance coverage for the treatment of other medical illnesses, is not a new idea, but the path to achieving "real parity" has been a long, hard and complex journey. Action by Congress to pass major parity legislation in 2008 was a huge step forward, but does not mean that parity has been achieved. Parity has required a paradigm shift in the understanding of addiction as a biological illness: many developments of science and policy changes by professional organizations and governmental entities have contributed to that paradigm shift. Access to adequate treatment for patients must acknowledge the paradigm shift reflected in parity as it has evolved to the current point: that this biological illness is widespread, that it is important that it be treated effectively, that appropriate third party payment for physician-provided or physician-supervised addiction treatment is critical for addiction medicine to become a part of the mainstream of our nation's healthcare delivery system, and that medical specialty care provides the most effective and cost effective benefit to patients and therefore to our society.

    Full Text Available Aim: Menopausal hot flashes affect the majority of women. Hormone replacement therapy to reduce the severity of hot flashes is the most effective method. Today, however, due to a number of side effects of hormone therapy more women are seeking alternative treatments such as vitamin pills and herbal products. Previously, various vitamins, minerals and trace elements were studied for this purpose. In this study, our aim was to determine the level of dietary intake of various vitamins in women with hot flashes and to compare them with women who had no complaints. Material and Method: One hundred and seven consecutive women who attended the menopause clinic of our hospital for routine follow up were included in this study. All of the participants were asked about the occurrence of specific menopausal symptoms and completed 92-itm antioxidant nutrient questionnaire developed by Satia.

    This work aims to study the associations, if any, of hyperuricemia, gout, and menopause status in the US population. Using multiyear data from the National Health and Nutrition Examination Survey, we performed unmatched comparisons and one to three age-matched comparisons of women aged 20 to 70 years with and without hyperuricemia (serum urate ≥6 mg/dL). Analyses were performed using survey-weighted multiple logistic regression and conditional logistic regression, respectively. Overall, there were 1,477 women with hyperuricemia. Age and serum urate were significantly correlated. In unmatched analyses (n = 9,573 controls), postmenopausal women were older, were heavier, and had higher prevalence of renal impairment, hypertension, diabetes, and hyperlipidemia. In multivariable regression, after accounting for age, body mass index, glomerular filtration rate, and diuretic use, menopause was associated with hyperuricemia (odds ratio, 1.36; 95% CI, 1.05-1.76; P = 0.002). In corresponding multivariable regression using age-matched data (n = 4,431 controls), the odds ratio for menopause was 0.94 (95% CI, 0.83-1.06). Current use of hormone therapy was not associated with prevalent hyperuricemia in both unmatched and matched analyses. Age is a better statistical explanation for the higher prevalence of hyperuricemia among older women than menopause status.

    The increase in lifespan and in the proportion of elderly women has increased the focus on menopause induced physiological alterations. These modifications are associated with the elevated risk of several pathologies such as cardiovascular disease, diabetes, obesity, hypertension, dyslipidemia, non-alcoholic fat liver disease, among others. Because of estrogen levels decline, many tissue and organs (muscular, bone, adipose tissue and liver) are affected. Additionally, body composition suffers important modifications. In this sense, there is a growing body of concern in understanding the physiological mechanisms involved and establishing strategies to prevent and reverse the effects of menopause. The hormone reposition therapy, diet and physical exercise have been recommended. Among the diverse exercise modalities, resistance training is not commonly used as a therapeutic intervention in the treatment of menopause. Thus, the aim of this review was to analyze the physiological alterations on several organs and systems induced by menopause and ovariectomy (experimental model to reproduce menopause), as well as, to study the effects of resistance training in preventing and reverting these modifications. In conclusion, resistance training promotes beneficial effects on several organs and systems, mainly, on muscular, bone and adipose tissue, allowing for a better quality of life in this population.

    While many women undergo menopausal transition while they are in paid employment, the effect of poor working conditions on women's experience of the menopause has received scant empirical attention. We examined associations between employment conditions, work-related stressors, and menopausal symptom reporting among perimenopausal and postmenopausal working women. Data were drawn from an online survey conducted between 2013 and 2014 involving 476 perimenopausal and postmenopausal women working in the higher education sector in Australia. Survey questions assessed demographics; health-related variables; menopausal symptom reporting; employment status; presence of flexible working hours; presence of temperature control; job autonomy; and supervisor support. A forced entry multivariable regression analysis revealed that high supervisor support (β = -0.10, P = 0.04), being employed on a full-time basis (β = -0.11, P = 0.02), and having control over workplace temperature (β = -0.11, P = 0.02) were independently associated with lower menopausal symptom reporting. These findings may help inform the development of tailored occupational health policies and programs that cater for the needs of older women as they transition through menopause in the workplace.

  17. Mental Health Insurance Parity and Provider Wages.

    Policymakers frequently mandate that employers or insurers provide insurance benefits deemed to be critical to individuals' well-being. However, in the presence of private market imperfections, mandates that increase demand for a service can lead to price increases for that service, without necessarily affecting the quantity being supplied. We test this idea empirically by looking at mental health parity mandates. This study evaluated whether implementation of parity laws was associated with changes in mental health provider wages. Quasi-experimental analysis of average wages by state and year for six mental health care-related occupations were considered: Clinical, Counseling, and School Psychologists; Substance Abuse and Behavioral Disorder Counselors; Marriage and Family Therapists; Mental Health Counselors; Mental Health and Substance Abuse Social Workers; and Psychiatrists. Data from 1999-2013 were used to estimate the association between the implementation of state mental health parity laws and the Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act and average mental health provider wages. Mental health parity laws were associated with a significant increase in mental health care provider wages controlling for changes in mental health provider wages in states not exposed to parity (3.5 percent [95% CI: 0.3%, 6.6%]; pwages. Health insurance benefit expansions may lead to increased prices for health services when the private market that supplies the service is imperfect or constrained. In the context of mental health parity, this work suggests that part of the value of expanding insurance benefits for mental health coverage was captured by providers. Given historically low wage levels of mental health providers, this increase may be a first step in bringing mental health provider wages in line with parallel health professions, potentially reducing turnover rates and improving treatment quality.

  18. Managing menopause: a critical feminist engagement.

    Feminist critiques of menopause have been beneficial in opening up important public health debates around menopause. One of the most contentious public health issues concerns the use of Hormone Replacement Therapy (HRT) for the prevention of osteoporosis, heart disease and, more recently, Alzheimer's disease, in postmenopausal women. For preventive purposes, it is recommended that women should take HRT for 10-15 years and preferably remain on the therapy for the remainder of their lives. This is despite reported increased cancer risks associated with HRT, side effects and considerable cost of the therapy. Various studies have shown that up to 50% of women stop taking HRT after 9-12 months. These figures are used in the medical literature as an indication of women's non-compliance. Extending earlier feminist critiques around menopause and HRT, this paper discusses a critical feminist engagement around issues of women's perceived non-compliance with HRT.

  19. [Hypertension in women (contraception and menopause].

    Beaufils, M

    2000-11-01

    There are three circumstances where hypertension develops specifically in women: oral contraception, pregnancy, and menopause. Oral contraception usually shifts the blood pressure moderately upwards, but hypertension appears in less than 5% of women. Still it may (rarely) be very severe. Hypertension is poorly related to the dosage of the estrogenic compound, but rather to the nature and dosage of the progestive part. This hypertension does not significantly increase the cardiovascular risk of these women. The role of menopause itself in the trigging of hypertension remains uncertain. It seems however that confounding factors such as age, body weight, sodium balance and so on explain the increased incidence of hypertension after menopause. The latter is also associated with an increase of cardiovascular risk, which requires adequate treatment. Hormone replacement therapy is not contra-indicated, even in hypertensive patients.

  20. The evolutionary origin and significance of Menopause

    Contemporary human females have long life expectancy (81y US), especially relative to age at menopause (51y US). Menopause is a consequence of reproductive aging and follicular depletion (ovarian failure), yielding very low circulating estrogen* serum concentrations and biologically disadvantageous metabolic alterations. Stated in terms of antagonistic pleiotropy, the ongoing hypoestrogenic endocrine environment, beneficial during lactation, results in acceleration of several age-related health conditions following menopause (i.e. late postmenopausal osteoporosis, cardiovascular disease and cognitive decline). In contrast, the complex hypoestrogenic hormonal milieu present during postpartum lactation provides biologic advantages to both mother and newborn. The lactational hormonal milieu causes symptoms similar to those of the late perimenopause and early postmenopause, prompting theories for their biologic selective advantage. The precepts of evolutionary medicine encourage a reassessment of hormone therapy. Based on data presented, the authors propose additional opportunities for disease prevention and morbidity reduction in postmenopausal women. PMID:21252729

As people with HIV are living longer, aging and its associated manifestations have become key priorities as part of HIV care. For women with HIV, menopause is an important part of aging to consider. Women currently represent more than one half of HIV-positive individuals worldwide. Given the vast proportion of women living with HIV who are, and will be, transitioning through age-related life events, the interaction between HIV infection and menopause must be addressed by clinicians and researchers. Menopause is a major clinical event that is universally experienced by women, but affects each individual woman uniquely. This transitional time in women’s lives has various clinical implications including physical and psychological symptoms, and accelerated development and progression of other age-related comorbidities, particularly cardiovascular disease, neurocognitive dysfunction, and bone mineral disease; all of which are potentially heightened by HIV or its treatment. Furthermore, within the context of HIV, there are the additional considerations of HIV acquisition and transmission risk, progression of infection, changes in antiretroviral pharmacokinetics, response, and toxicities. These menopausal manifestations and complications must be managed concurrently with HIV, while keeping in mind the potential influence of menopause on the prognosis of HIV infection itself. This results in additional complexity for clinicians caring for women living with HIV, and highlights the shifting paradigm in HIV care that must accompany this aging and evolving population

    Menopause is a natural phenomenon of aging, although the timing and management of menopause can significantly affect a woman's quality of life. It is therefore important to identify measures to ensure a healthy menopause. We set out to investigate the association between hypertension and early menopause in Korean women. This cross-sectional study was based on 2008-2013 data from the Korea National Health and Nutrition Examination Survey (KNHANES). Of the 53,829 participants surveyed, 13,584 women were selected. We analyzed the contents of the health interview, health examination, and nutrition survey. The main outcome was defined based on hazard ratios (HR) to identify the effects of hypertension on age at onset of menopause. Among postmenopausal women (n=6650), the mean age at onset of menopause was 50.4 years. Premenopausal hypertension was statistically significantly associated with age at menopause, oral contraceptive usage, household income, education level, occupation, marital status and smoking and drinking habits. With lower age at diagnosis of hypertension, HRs for menopause tended to be higher, and hypertension diagnosed before age 40 years conferred a statistically significantly higher HR (Model 1, HR=2.32, 95% CI=1.87-2.88; Model 2, HR=2.31, 95% CI=1.86-2.86; Model 3, HR=2.23, 95% CI=1.80-2.77; Model 4, HR=2.00, 95% CI=1.52-2.63). Premature menopause is strongly associated with lifestyle factors, in combination with incomplete management of chronic diseases. Our findings support the hypothesis that younger age at diagnosis of hypertension is associated with younger age at onset of menopause in Korean women. Copyright © 2016 Elsevier Ireland Ltd.

    The condition of nerves among women in the small Peruvian town of Puente Piedre is described. Both nervios (a symptom) and Nervios (a disorder) describe a woman's difficulty with nerves. In Puente Piedre, the identification of an anxiety condition among women depends only on the women's age. Younger women with anxiety symptoms are diagnosed as nervios, a temporary condition ascribed to a single episode of high blood pressure. Menopausal women with similar symptoms, on the other hand, are thought to have a specific disorder, Nervios. In Puente Piedre, Nervios clearly is a folk illness limited to women of menopausal age.

    We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, N r a rrow ∞. At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = T d , is of second order. Then we argue that Witten's relation implies that the topological susceptibility vanishes in a calculable fashion at Td. As noted by Witten, this implies that for sufficiently light quark masses, metastable states which act like regions of nonzero θ--parity odd bubbles--can arise at temperatures just below T d . Experimentally, parity odd bubbles have dramatic signatures: the ηprime meson, and especially the η meson, become light, and are copiously produced. Further, in parity odd bubbles, processes which are normally forbidden, such as η r a rrow π 0 π 0 , are allowed. The most direct way to detect parity violation is by measuring a parity odd global asymmetry for charged pions, which we define

At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = T{sub d}, is of second order.

As noted by Witten, this implies that for sufficiently light quark masses, metastable states which act like regions of nonzero {theta}--parity odd bubbles--can arise at temperatures just below T{sub d}. Experimentally, parity odd bubbles have dramatic signatures: the {eta}{prime} meson, and especially the {eta} meson, become light, and are copiously produced.

    Full Text Available We present a new tool for verification of modal mu-calculus formulae for process specifications, based on symbolic parity games. It enhances an existing method, that first encodes the problem to a Parameterised Boolean Equation System (PBES and then instantiates the PBES to a parity game. We improved the translation from specification to PBES to preserve the structure of the specification in the PBES, we extended LTSmin to instantiate PBESs to symbolic parity games, and implemented the recursive parity game solving algorithm by Zielonka for symbolic parity games. We use Multi-valued Decision Diagrams (MDDs to represent sets and relations, thus enabling the tools to deal with very large systems. The transition relation is partitioned based on the structure of the specification, which allows for efficient manipulation of the MDDs. We performed two case studies on modular specifications, that demonstrate that the new method has better time and memory performance than existing PBES based tools and can be faster (but slightly less memory efficient than the symbolic model checker NuSMV.

    Plasma zinc and copper status of 1689 non pregnant Tunisian women, aged 20-49 years old, was determined by flame atomic absorption spectrometry. A multiple regression was run to predict plasma trace element concentrations from age, BMI, marital status, menopause, education level, professional activity, economic level and area of living. The mean zinc and copper values were similar to those measured among comparable populations in earlier studies. However, a high prevalence of low plasma zinc and copper concentrations was observed assuming that women at childbearing age are at high risk of zinc and copper deficiencies and specific intervention may be considered. In univariate analysis, the mean values of plasma zinc and copper were associated with sitting areas and professional activity. For only plasma copper levels, there was an increase with BMI and parity, and a decrease with increasing schooling level and economic score. After adjustment for all variables, profession and parity showed a significant relationship between plasma levels copper. Copyright © 2016 Elsevier Ltd. All rights reserved.

    1990-01-01

    We study a mechanism for parity violation in the two nucleon meson-exchange interaction by way of the mixing of mesons of opposite parities. This mixing arises from parity violating W ± and Z exchange between the q bar q pair in the meson. Numerically its effect turns out to be as important as vector meson exchange with a weak meson-nucleon vertex and may partly be used to model this vertex. The calculation is performed using both the standard Born approximation adding the amplitude phases by Watson's theorem and also using the exact correlated two-nucleon wave functions. The effect of correlations and form factors is found to be crucially important at intermediate energies

    This study explores the attitude and feelings toward menopause among Azeri menopausal women using hermeneutic phenomenology based on Van Manen's approach. A total of 18 menopausal women who were attended in urban health centers of Tabriz, Iran, were recruited using a purposive sampling method. Data were gathered through semistructured interviews. Each interview was transcribed verbatim and analyzed simultaneously. Data analysis led to the emergence of five main themes: positive attitude, neutral attitude, negative attitude, positive feelings, and negative feelings. Participants had different feelings and attitude. Acceptance of menopause as a natural process helps women to have a neutral attitude toward menopause.

    To detect and visualize salient queries about menopause using Big Data from ChaCha. We used Word Adjacency Graph (WAG) modeling to detect clusters and visualize the range of menopause-related topics and their mutual proximity. The subset of relevant queries was fully modeled. We split each query into token words (ie, meaningful words and phrases) and removed stopwords (ie, not meaningful functional words). The remaining words were considered in sequence to build summary tables of words and two and three-word phrases. Phrases occurring at least 10 times were used to build a network graph model that was iteratively refined by observing and removing clusters of unrelated content. We identified two menopause-related subsets of queries by searching for questions containing menopause and menopause-related terms (eg, climacteric, hot flashes, night sweats, hormone replacement). The first contained 263,363 queries from individuals aged 13 and older and the second contained 5,892 queries from women aged 40 to 62 years. In the first set, we identified 12 topic clusters: 6 relevant to menopause and 6 less relevant. In the second set, we identified 15 topic clusters: 11 relevant to menopause and 4 less relevant. Queries about hormones were pervasive within both WAG models. Many of the queries reflected low literacy levels and/or feelings of embarrassment. We modeled menopause-related queries posed by ChaCha users between 2009 and 2012. ChaCha data may be used on its own or in combination with other Big Data sources to identify patient-driven educational needs and create patient-centered interventions.

    The possibility to extract from the experiment the necessary information concerning the charged and neutral current contributions to the structure of the weak interactions that violate the parity conservation law is investigated. The parity nonconservation (PNC) induced by weak hadron-hadron interactions, investigated via 'pairs' of low energy nuclear physics processes, is proposed. The low energy physics processes considered here are emission of polarized gamma rays from oriented and unoriented nuclei. Some comments on PNC nucleon-nucleon (PNC-NN) interaction are presented. Explicit expressions for some gamma asymmetry PNC observables are retrieved. Applications to A=19 atomic nuclei are done. A new experiment is proposed. (authors)

(Moscow), of his quantum number isotopic parity as a consequence of the charge symmetry of nuclear forces, a property generally accepted as early as 1936. His applications of it are discussed and it is demonstrated from the data today that his tentative suggestion that the small partial width (∼35 eV) for α-decay from 20 Ne (13.649 MeV) to 16 O was due to isotopic parity violation was correct

    Khokhlachev, S.B.

    1990-01-01

    The nature of parity doubling of baryon states with non-zero angular momentum is considered. The idea of explaining this phenomenon lies in the fact that the rotation of the gluon string leads to a centrifugal potential for quarks. The quarks on the string form a quark-diquark system. Quark tunneling from one end of the string to the other is not probable for systems with large angular momentum due to a large centrifugal potential, and the smallness of the underbarrier transition amplitude explains the small mass difference of the states with opposite parity.

    Maternal smoking during pregnancy causes a delay of intrauterine growth. To examine the effect of maternal smoking during pregnancy on fetal growth in relationship to maternal parity, age and number of cigarettes smoked/day, and offspring's gender. We studied 2,108 term newborns (1,102 male, 1,006 female) delivered at the General University Hospital of Patras from 1994 to 2004. The 1,443 were born to mothers who did not smoke and 665 to mothers who smoked during pregnancy. Birth weight, length and head circumference were measured prospectively in all newborns. Also, maternal smoking status and number of cigarettes smoked per day, age, and parity were recorded. For the analysis, t test, one-way ANOVA, Mann-Whitney U test, Spearman rank correlation, and factorial MANOVA with covariates were used. With increasing parity, in the neonates of nonsmoking mothers there was a gradual increase of growth, whereas in neonates of smoking mothers there was a gradual decrease of growth. This effect was more pronounced in males. A significant negative main effect on growth resulted from the interaction of smoking with parity (p = 0.013), and with gender and parity (p = 0.001). There was a significant negative correlation between number of cigarettes smoked per day and growth, the strength of which increased with parity, mainly in males. Maternal smoking during pregnancy causes a delay in fetal growth, which is greater in male offspring, an effect that is enhanced with parity but is independent of maternal age. (c) 2008 S.

    Increasing breast cancer incidence and decreasing mortality have highlighted the importance of survivorship issues related to breast cancer. A consideration of the issues related to menopause is therefore of great importance to both women and clinicians. Menopause/menopausal symptoms, with significant negative effects on quality of life and potential long-term health impacts, may in women with breast cancer be associated with: (1) natural menopause occurring concurrently with a breast cancer diagnosis; (2) recurrence of menopausal symptoms following cessation of hormone replacement therapy; (3) treatment-induced menopause (chemotherapy, ovarian ablation/suppression) and adjuvant endocrine therapy. A variety of non-hormonal pharmacological and non-pharmacological therapies have been investigated as therapeutic options for menopausal symptoms with mixed results, and ongoing research is required. This review presents a summary of the causes, common problematic symptoms of menopause (vasomotor, genitourinary and sexual dysfunction), and longer-term consequences (cardiovascular disease and osteoporosis) related to menopause. It proposes an evidenced-based multidisciplinary approach to the management of menopause/menopausal symptoms in women with breast cancer.

    To measure the impact of menopause on work ability in women with severe menopausal symptoms. This cross-sectional study compared the work ability of a sample of otherwise healthy employed Dutch women (n=205) with that of a sample of first-time attendees of a menopause clinic (n=60); both groups were aged 44-60 years. Self-reported questionnaire data assessing work ability (Work Ability Index; WAI) and menopausal symptoms (Greene Climacteric Scale; GCS) were used. Logistic regression analyses were used to examine whether women with severe menopausal symptoms were more likely to have low work ability (defined as a score work ability than their healthy counterparts: 76.7% versus 30.2% (OR 8.4, 95% CI 4.1-17.2). Over three-quarters of symptomatic menopausal women report serious problems in dealing with the physical and mental demands of their work (recorded here as low work ability); hence these women might be at risk of prolonged sickness absence from work.

  3. Res-Parity: Parity Violation in Inelastic scattering at Low Q2

    2006-01-01

    Parity violating electron scattering has become a well established tool which has been used, for example, to probe the Standard Model and the strange-quark contribution to the nucleon. While much of this work has focused on elastic scattering, the RES-Parity experiment, which has been proposed to take place at Jefferson Laboratory, would focus on inelastic scattering in the low-Q 2 , low-W domain. RES-Parity would search for evidence of quark-hadron duality and resonance structure with parity violation in the resonance region. In terms of parity violation, this region is essentially unexplored, but the interpretation of other high-precision electron scattering experiments will rely on a reasonable understanding of scattering at lower energy and low-W through the effects of radiative corrections. RES-Parity would also study nuclear effects with the weak current. Because of the intrinsic broad band energy spectrum of neutrino beams, neutrino experiments are necessarily dependent on an untested, implicit assumption that these effects are identical to electromagnetic nuclear effects. RES-Parity is a relatively straight forward experiment. With a large expected asymmetry (∼ 0.5 x 10 -4 ) these studies may be completed with in a relatively brief period

    Full Text Available Introduction: It is considered that the lifestyle conditioned by socio-demographic or socio-economic factors determines the health condition of people to the greatest extent. The aim of this study is to evaluate the influence of selected socio-demographic factors on the kinds of symptoms occurring during menopause. Material and methods : The study group consisted of 210 women aged 45 to 65, not using hormone replacement therapy, staying at healthcare centers for rehabilitation treatment. The study was carried out in 2013-2014 in the Silesian, Podlaskie and Lesser Poland voivodeships. The set of tools consisted of the authors’ own survey questionnaire and the Menopause Rating Scale (MRS. Results : The most commonly occurring symptom in the group of studied women was a depressive mood, from the group of psychological symptoms, followed by physical and mental fatigue, and discomfort connected with muscle and joint pain. The greatest intensity of symptoms was observed in the group of women with the lowest level of education, reporting an average or bad material situation, and unemployed women. Conclusions : An alarmingly high number of reported psychological symptoms in the group of menopausal women was observed, and in particular among the group of low socio-economic status. Career seems to be a factor reducing the risk of occurrence of psychological symptoms. There is an urgent need for health promotion and prophylaxis in the group of menopausal women, and in many cases for implementation of specialist psychological assistance.

    The aim of this study was to determine the relationship between self-reported sleep quality, menopausal symptom intensity, and correlates (including ethnicity) among middle-aged women. The present cross-sectional study involved 1,078 Colombian women aged 40 to 59 years who completed the Pittsburgh Sleep Quality Index (PSQI), the Menopause Rating Scale (MRS), and a general questionnaire exploring sociodemographic data. The median [interquartile range] age of the whole sample was 49.0 [9.0] years. Among the participants, 45.4% were postmenopausal, 57.2% had increased body mass index values, 13.9% were black, 20.7% had hypertension, 74.1% had a stable partner, and 3.8% used hormone therapy. The prevalence of poor sleep quality was 57.1% (PSQI global score ≥5). Significant correlations between PSQI global scores and MRS total and subscale scores were found. Multiple linear regression analysis found that higher PSQI scores (poorer quality of sleep) correlated with higher MRS psychological and somatic subscale scores (more severe symptoms), smoking habit, and hypertension. Menopause status and black ethnicity were excluded from the final regression model. Despite study limitations, poor sleep quality is highly prevalent in this large middle-aged Colombian female sample and is related to menopausal symptom severity, tobacco use, and presence of hypertension.

    OBJECTIVE: To determine the age of menopause after premenopausal unilateral oophorectomy (UO) and to establish whether UO at a young age leads to menopause at a younger age than if UO occurs at an older age. METHODS: A cohort of 28 731 women, of whom 17 781 (62%) were menopausal, was investigated....... Information on menopause was obtained from self-reported questionnaires. Surgical data were obtained from the National Patient Register to avoid recollection bias. Age of menopause after UO/not UO was determined using Kaplan-Meier curves. Cox regression was used to identify factors of importance for early...... menopause. RESULTS: UO was performed in 1148 women. Women with UO after the age of 45 years, premenopausal hysterectomy, bilateral oophorectomy and cancer were excluded, leaving 236 in the analysis. Menopause occurred 1.8 years earlier after UO compared to women with two intact ovaries (mean 49.5 vs. 51...

    2002-11-01

    To review the topic of urinary tract infections (UTI) during pregnancy and menopause. UTI during pregnancy and menopause have great relevance in the field of urologic infections; during pregnancy because of the particularities involved in its diagnosis and treatment and potential consequences to the fetus and mother; menopausal UTI because this group of women is numerous and represents a growing section of the general population pyramid, due to the aging of population in developed countries associated with longer life expectancies and grater demand for quality of life. We performed a bibliographic review combined with our personal experience. During pregnancy there are several functional and anatomical changes that condition not only a higher risk of UTI, but also an additional treatment difficulty due to antimicrobial pharmacokinetics alterations and potential damage to the fetus. Despite efforts to find an easy, fast and reliable test for bacteriuria detection, urine culture continues to be the first diagnostic test for its detection and follow up during pregnancy. Penicillin derivates and cephalosporins continue to be the first choice because their lack of adverse effects on either fetus or mother. Alternative options like phosphomicin and aztreonam although they show low toxicity there is need for more studies supporting their suitability for the treatment of pregnancy UTIs. Menopausal female UTI have their different features from those in younger women. Hormonal alterations derived from gonadal atrophy associate functional changes in the vaginal ecosystem, making it prone to enterobacteriaceae colonization as a first step up to the urinary tract. This associated with genitourinary tract anatomical alterations inherent t aging make UTI extraordinary prevalent in this growing segment of population. Treatment lines focus on hormonal alteration correction and proper antimicrobial prophylaxis and vaccines in a close future. UTIs during pregnancy and menopause have

  8. Premature menopause linked to CVD and osteoporosis.

    2010-03-01

    Premature menopause affects 1% of women under the age of 40, the usual age of the menopause is 51. Most women will present with irregular periods or no periods at all with or without climacteric symptoms. Around 10% of women present with primary amenorrhoea. A careful history and examination are required. It is important to ask specifically about previous chemotherapy or radiotherapy and to look for signs of androgen excess e.g. polycystic ovarian syndrome, adrenal problems e.g. galactorrhoea and thyroid goitres. Once pregnancy has been excluded, a progestagen challenge test can be performed in primary care. Norethisterone 5 mg tds po for ten days or alternatively medroxyprogesterone acetate 10 mg daily for ten days is prescribed. A withdrawal bleed within a few days of stopping the norethisterone indicates the presence of oestrogen and bleeding more than a few drops is considered a positive withdrawal bleed. The absence of a bleed indicates low levels of oestrogen, putting the woman at risk of CVD and osteoporosis. FSH levels above 30 IU/l are an indicator that the ovaries are failing and the menopause is approaching or has occurred. It should be remembered that FSH levels fluctuate during the month and from one month to the next, so a minimum of two measurements should be made at least four to six weeks apart. The presence of a bleed should not exclude premature menopause as part of the differential diagnosis as there can be varying and unpredictable ovarian function remaining. The progestagen challenge test should not be used alone, but in conjunction with FSH, LH and oestradiol. There is no treatment for premature menopause. Women desiring pregnancy should be referred to a fertility clinic and discussion of egg donation. Women not wishing to become pregnant should be prescribed HRT until the age of 50 to control symptoms of oestrogen deficiency and reduce the risks of osteoporosis and CVD.

  9. Searches for Prompt R-Parity-Violating Supersymmetry at the LHC

    2015-01-01

    Searches for supersymmetry (SUSY) at the LHC frequently assume the conservation of R-parity in their design, optimization, and interpretation. In the case that R-parity is not conserved, constraints on SUSY particle masses tend to be weakened with respect to R-parity-conserving models. We review the current status of searches for R-parity-violating (RPV) supersymmetry models at the ATLAS and CMS experiments, limited to 8 TeV search results published or submitted for publication as of the end of March 2015. All forms of renormalisable RPV terms leading to prompt signatures have been considered in the set of analyses under review. Discussing results for searches for prompt R-parity-violating SUSY signatures summarizes the main constraints for various RPV models from LHC Run I and also defines the basis for promising signal regions to be optimized for Run II. In addition to identifying highly constrained regions from existing searches, also gaps in the coverage of the parameter space of RPV SUSY are outlined

    Menopause can be a time of change for women and may be marked by disturbances in mood. For women living with a mental illness, such as bipolar disorder, little is known about how they experience mood changes during menopause. This study aimed to explore how women with bipolar disorder constructed mood changes during menopause and how this impacted on treatment decisions. Semi-structured interviews were undertaken with fifteen women who reported they had been diagnosed with bipolar disorder. Data was analysed using thematic analysis guided by a social constructionist framework. Themes identified included 'Constructions of mood change: menopause or bipolar disorder?',' Life events, bipolar disorder and menopause coming together'; 'Treatment choices for mood change during menopause'. The accounts suggested that women related to the experience of mood changes during menopause through the lens of their existing framework of bipolar disorder, with implications for understanding of self and treatment choices.

    A recent study identified increasing birth order to be a risk factor for the development of systemic sclerosis (SSc). This finding supports the theory that transplacental microchimerism may be a key pathological event in the initiation of SSc. We investigated the relationship between birth order and parity and the age of onset of SSc in South Australia. A retrospective analysis of patient data in the South Australian Scleroderma Register was performed. Data were obtained from a mailed questionnaire. Control data was collected prospectively using a similar questionnaire. The relationship between birth order, family size or parity and risk of subsequent development of SSc was analyzed by mixed effects logistic regression analysis. Three hundred and eighty-seven index probands were identified and compared with 457 controls. Controls were well matched for gender, but not for age. No statistically significant relationship was identified between SSc and birth order, parity in females, family size, age at first pregnancy in females or gender of first child in parous females. Our data suggests that parity, age at first pregnancy and the gender of the first child are not relevant factors in our understanding of the epidemiology and pathogenesis of SSc. Birth order and family size in both genders also appears irrelevant. These results argue against microchimerism as being relevant in the pathogenesis of SSc and add further support to the theory that stochastic events may be important in the etiopathogenesis of SSc. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    Schöndorf, M.; Wilhelm, F. K.

    2018-04-01

    Robust high-fidelity parity measurement is an important operation in many applications of quantum computing. In this work we show how in a circuit QED architecture, one can measure parity in a single shot at very high contrast by taking advantage of the nonlinear behavior of a strongly driven microwave cavity coupled to one or multiple qubits. We work in a nonlinear dispersive regime treated in an exact dispersive transformation. We show that appropriate tuning of experimental parameters leads to very high contrast in the cavity and therefore to a high-efficiency parity readout with a microwave photon counter or another amplitude detector. These tuning conditions are based on nonlinearity and are hence more robust than previously described linear tuning schemes. In the first part of the paper we show in detail how to achieve this for two-qubit parity measurements and extend this to N qubits in the second part of the paper. We also study the quantum nondemolition character of the protocol.

    To assess the relationship between menopause and age at menopause and the risk of the first non-fatal myocardial infarction taking into account the possible influence of psychosocial job characteristics, marital stress, level of social support, educational level, occupation, age and traditional ischemic heart disease risk factors. Population-based case-control study among 35-61 years old employed women in Kaunas, Lithuania. Totally 122 myocardial infarction cases and 371 controls were interviewed in 2001-2004. The logistic regression analysis was performed. Younger age at menopause (women was 1.15; 95% CI 0.48-2.75. The association between low job control and myocardial infarction showed step increase, women in the lowest quartile of job control had the highest myocardial infarction risk (OR=4.51; 95% CI 1.90-10.75), while those in the second and third quartiles showed modest risk. Marital stress was an independent myocardial infarction risk factor for employed women (adjusted OR=2.36; 95% CI 1.07-5.19). Menopausal status and younger age at menopause showed only a tendency for increase in myocardial infarction risk among the employed women in Kaunas, Lithuania. Adverse psychosocial job characteristics as low job control, as well as marital stress play more important role in the development of the first myocardial infarction.

    [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.

Since the first step in providing support is having adequate knowledge, this study aimed to investigate the effects of an educational program on menopause health for spouses on women's quality of life during the menopausal transition. This clinical trial was conducted in Yazd, Iran. A hundred healthy women aged 45 to 60 years were recruited by random sampling. The spouses in the intervention group (n = 50) attended three training sessions about the management and health of menopausal transition. The spouses in the control group (n = 50) did not receive any intervention. Knowledge and performance about menopausal health were assessed in all spouses before and 3 months after intervention. All women were assessed by the Menopause Rating Scale, and the Menopause Quality of Life questionnaire before and 3 months after educational intervention. Analyses were carried out using SPSS 16 software. The level of significance was set at P less than 0.05. The knowledge and performance of spouses in the intervention group were significantly higher 3 months after intervention (P women in the intervention group was higher 3 months after intervention (P training of menopausal health for spouses improves the quality of life in women during menopausal transition. We suggest integrating such educational programs in menopausal management programs.

    Purpose Age at menopause, a major marker in the reproductive life, may bias results for evaluation of breast cancer risk after menopause. Methods We follow 38,948 premenopausal women in 1980 and identify 2,586 who reported hysterectomy without bilateral oophorectomy, and 31,626 who reported natural menopause during 22 years of follow-up. We evaluate risk factors for natural menopause, impute age at natural menopause for women reporting hysterectomy without bilateral oophorectomy and estimate the hazard of reaching natural menopause in the next 2 years. We apply this imputed age at menopause to both increase sample size and to evaluate the relation between postmenopausal exposures and risk of breast cancer. Results Age, cigarette smoking, age at menarche, pregnancy history, body mass index, history of benign breast disease, and history of breast cancer were each significantly related to age at natural menopause; duration of oral contraceptive use and family history of breast cancer were not. The imputation increased sample size substantially and although some risk factors after menopause were weaker in the expanded model (height, and alcohol use), use of hormone therapy is less biased. Conclusions Imputing age at menopause increases sample size, broadens generalizability making it applicable to women with hysterectomy, and reduces bias. PMID:21441037

    This study aims to assess whether the timing of menopausal hormone therapy initiation in relation to onset of menopause and hormone therapy duration is associated with myocardial infarction risk. This study was based on the Stockholm Heart Epidemiology Program, a population-based case-control study including 347 postmenopausal women who had experienced a nonfatal myocardial infarction and 499 female control individuals matched for age and residential area. Odds ratios (with 95% CIs) for myocardial infarction were calculated using logistic regression. Early initiation of hormone therapy (within 10 y of onset of menopause or before age 60 y), compared with never use, was associated with an odds ratio of 0.87 (95% CI, 0.58-1.30) after adjustments for lifestyle factors, body mass index, and socioeconomic status. For late initiation of hormone therapy, the corresponding odds ratio was 0.97 (95% CI, 0.53-1.76). For hormone therapy duration of 5 years or more, compared with never use, the adjusted odds ratio was 0.64 (95% CI, 0.35-1.18). For hormone therapy duration of less than 5 years, the odds ratio was 0.97 (95% CI, 0.63-1.48). Neither the timing of hormone therapy initiation nor the duration of therapy is significantly associated with myocardial infarction risk.

  13. TIME HORIZON AND UNCOVERED INTEREST PARITY IN EMERGING ECONOMIES

    Full Text Available The aim of this study is to re-examine the well-known empirical puzzle of uncovered interest parity (UIP for emerging market economies with different prediction time horizons. The empirical results obtained using dynamic panel and time series techniques for monthly data from January 1995 to December 2009 eventually show that the panel data estimates are more powerful than those obtained by applying individual time series estimations and the significant contribution of the exchange rate prediction horizons in determining the status of UIP. This finding reveals that at the longer time horizon, the model has better econometric specification and thus more predictive power for exchange rate movements compared to the shorter time period. The findings can also be a signalling of well-integrated currency markets and a reliable guide to international investors as well as for the orderly conduct of monetary authorities.

  14. Sleep and menopause: a narrative review.

    2015-08-01

    Our overall aim-through a narrative review-is to critically profile key extant evidence of menopause-related sleep, mostly from studies published in the last decade. We searched the database PubMed using selected Medical Subject Headings for sleep and menopause (n = 588 articles). Using similar headings, we also searched the Cochrane Library (n = 1), Embase (n = 449), Cumulative Index to Nursing and Allied Health Literature (n = 163), Web of Science (n = 506), and PsycINFO (n = 58). Articles deemed most related to the purpose were reviewed. Results were articulated with interpretive comments according to evidence of sleep quality (self-reported) and sleep patterns (polysomnography and actigraphy) impact as related to reproductive aging and in the context of vasomotor symptoms (VMS; self-reported), vasomotor activity (VMA) events (recorded skin conductance), depressed mood, and ovarian hormones. Predominantly, the menopausal transition conveys poor sleep beyond anticipated age effects. Perceptions of sleep are not necessarily translatable from detectable physical sleep changes and are probably affected by an emotional overlay on symptoms reporting. Sleep quality and pattern changes are mostly manifest in wakefulness indicators, but sleep pattern changes are not striking. Likely contributing are VMS of sufficient frequency/severity and bothersomeness, probably with a sweating component. VMA events influence physical sleep fragmentation but not necessarily extensive sleep loss or sleep architecture changes. Lack of robust connections between perceived and recorded sleep (and VMA) could be influenced by inadequate detection. There is a need for studies of women in well-defined menopausal transition stages who have no sleep problems, accounting for sleep-related disorders, mood, and other symptoms, with attention to VMS dimensions, distribution of VMS during night and day, and advanced measurement of symptoms and physiologic manifestations.

  16. Menopause and cardiovascular disease: the evidence.

    2007-02-01

    Menopause is a risk factor for cardiovascular disease (CVD) because estrogen withdrawal has a detrimental effect on cardiovascular function and metabolism. The menopause compounds many traditional CVD risk factors, including changes in body fat distribution from a gynoid to an android pattern, reduced glucose tolerance, abnormal plasma lipids, increased blood pressure, increased sympathetic tone, endothelial dysfunction and vascular inflammation. Many CVD risk factors have different impacts in men and women. In postmenopausal women, treatment of arterial hypertension and glucose intolerance should be priorities. Observational studies and randomized clinical trials suggest that hormone replacement therapy (HRT) started soon after the menopause may confer cardiovascular benefit. In contrast to other synthetic progestogens used in continuous combined HRTs, the unique progestogen drospirenone has antialdosterone properties. Drospirenone can therefore counteract the water- and sodium-retaining effects of the estrogen component of HRT via the renin-angiotensin-aldosterone system, which may otherwise result in weight gain and raised blood pressure. As a continuous combined HRT with 17beta-estradiol, drospirenone has been shown to significantly reduce blood pressure in postmenopausal women with elevated blood pressure, but not in normotensive women. Therefore, in addition to relieving climacteric symptoms, drospirenone/17beta-estradiol may offer further benefits in postmenopausal women, such as improved CVD risk profile.

    Women form a large part of many workforces throughout Europe. Many will be working throughout their menopausal years. Whilst the menopause may cause no significant problems for some, for others it is known to present considerable difficulties in both their personal and working lives. During the menopausal transition women report that fatigue and difficulties with memory and concentration can have a negative impact on their working lives. Furthermore, hot flushes can be a source of embarrassme...

    Tsoy, Eduard N., E-mail: etsoy@uzsci.net

    2017-02-05

    Different models of coupled oscillators with parity-time (PT) symmetry are studied. Hamiltonian functions for two and three linear oscillators coupled via coordinates and accelerations are derived. Regions of stable dynamics for two coupled oscillators are obtained. It is found that in some cases, an increase of the gain-loss parameter can stabilize the system. A family of Hamiltonians for two coupled nonlinear oscillators with PT-symmetry is obtained. An extension to high-dimensional PT-symmetric systems is discussed. - Highlights: • A generalization of a Hamiltonian system of linear coupled oscillators with the parity-time (PT) symmetry is suggested. • It is found that an increase of the gain-loss parameter can stabilize the system. • A family of Hamiltonian functions for two coupled nonlinear oscillators with PT-symmetry is obtained.

  20. Photovoltaic is redolent of grid parity

    International Nuclear Information System (INIS)

    Signoret, Stephane

    2015-01-01

    This article indicates and comments the current trends of decrease of photovoltaic costs and increase of electricity prices. As a result, grid parity is starting to be reached in some countries (Mexico city, California, Australia, Italy, Germany, Israel, Chile) and nearly in southern France only, as the prices of residential electricity are rather low and therefore don't give any chance to network parity for solar photovoltaic. Curves of evolutions of photovoltaic costs and retail electricity prices are given for different towns (Berlin, London, Rome, Madrid, Marseilles, San Francisco, Sydney, and Copiapo in Chile). These evolutions are a positive factor for the development of self-consumption. The article thus evokes the PV-NET project which gathers several European regions or countries to test and assess different economic solutions of self-consumption

    1975-01-01

    The observation of a violation of the parity symmetry in two-nucleon systems implies the presence of a weak hadronic force. The positive effect reported by Lobashov et al. in the reaction np → dγ, for the circular polarization of the gamma ray, would imply a large value for the parity nonconserving (PNC) amplitude. A transmission experiment has been undertaken for 15-MeV longitudinally polarized protons on hydrogen. A transmission experiment for 6-GeV polarized protons on Be and on H 2 O is in progress at the ZGS at Argonne National Laboratory. The current results of the latter two experiments are summarized, and the relation to theoretical calculations is discussed. (2 figures, 1 table) (U.S.)

    1986-01-01

    The analysis of the transient performance of nuclear plants is sufficiently complex that simulation tools are needed for design and safety studies. The simulation tools are needed for design and safety studies. The simulation tools are normally digital because of the speed, flexibility, generality, and repeatability of digital computers. However, communication with digital computers is an awkward matter, requiring special skill or training. The designer wishing to gain insight into system behavior must expend considerable effort in learning to use computer codes, or else have an intermediary communicate with the machine. There has been a recent development in analog simulation that simplifies the user interface with the simulator, while at the same time improving the performance of analog computers. This development is termed parity simulation and is now in routine use in analyzing power electronic network transients. The authors describe the concept of parity simulation and present some results of using the approach to simulate neutron kinetics problems

    1984-01-01

    A measurement of parity nonconserving optical rotation has been performed on the 1.28 μm atomic lead magnetic dipole transition. Although the technique used in this measurement was similar to that used in earlier measurements done on the 0.876 μm line in atomic bismuth, important differences exist. These are discussed in detail. Since the accuracy of this measurement is limited by systematic errors, a complete analysis of the data is included with a lengthy discussion of systematic effects. The final value obtained for the optical rotation is given. This agrees with atomic calculations based on the Weinberg-Salam-Galshow model for weak interactions. A discussion of the limits on weak interaction theories placed by all the atomic parity nonconservation experiments appears in the conclusion

    Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. These documents inform and shape patient care around the world. In this Perspective we discuss the importance of diversity on guideline panels, the disproportionately low representation of women on critical care guideline panels, and existing initiatives to increase the representation of women in corporations, universities, and government. We propose five strategies to ensure gender parity within critical care medicine.

    The odd-parity baryons have provided a graveyard for many cherished ideas about hadrons. The simple quark shell model, with QCD-inspired phenomenological perturbations, is the only model able to describe the states with even partial qualitative success. There are also important unexplained residual dynamical effects. Resonance decays can be accounted for, provided the usual spectator model is abandoned. Better experimental data could help to sort out the many remaining puzzles

    Abstract. After the collapse of the Bretton Woods system, the evidence on the purchasing power parity (PPP) in the long run is still a matter of debate. The difficulties of the problem are the possible nonstationarity of relative price indices and nominal exchange rates. The traditional ways to deal with nonstationarity such as unit root model and cointegration have some problems. In this paper, to deal with nonstationarity, we apply the Hodrick-Prescott (HP) trend-cycle filter in real busine...

    Our previous study is extended to negative parity baryon resonances up to J=(9/2) - . The framework is a semi-relativistic constituent quark model. The quark-quark interaction contains a Coulomb plus linear confinement terms and a short distance spin-spin and tensor terms. It is emphasized that a linear confinement potential gives too large a mass to the D 35 (1930) resonance. (orig.)

    Measurements have been performed on the helicity dependence of the neutron resonance cross section for many nuclei by our TRIPLE Collaboration. A large number of parity violations are observed. Generic enhancements amplify the signal for symmetry breaking and the stochastic properties of the compound nucleus permit the strength of the symmetry-breaking interaction to be determined without knowledge of the wave functions of individual states. A total of 15 nuclei have been analyzed with this statistical approach. The results are summarized

    Background Acute menopausal syndrome especially hot flashes, is one of the most common gynecological problems during menopause. Due to the side effects of hormone therapy, herbal and complementary medicines are always of immense interest to people in the treatment and management of the symptoms and complications of menopause. Objective The aim of this study was to investigate the mechanisms and effects of medicinal plants employed in the treatment of menopausal symptoms. Methods This review article was carried out by examining clinical trial studies between the period of 1994 and 2016. The keywords, which include menopause, climacteric, hot flushes, flashes, herb and phytoestrogens were used to search for herbal medicines used in clinical trials for the treatment of menopausal symptoms using databases such as PubMed, Medline, Scopus, Google scholar, SID and Magiran. Results The results of the study showed that the medicinal plants, which include Sage herb (Salvia officinalis), Lemon balm (Melissa officinalis), Valerina officinalis, Black cohosh (Cimicifuga racemosa), Fenugreek (Trigonella foenum-graecum), Black cumin (Nigella sativa), Vitex (Vitex agnus-castus), Fennel (Foeniculum vulgare), Evening primrose (Oenothera biennis), Ginkgo biloba, Alfalfa (Medicago sativa), Hypericum perforatum, Panax ginseng, Pimpinella anisum, Licorice (Glycyrrhiza glabra), Passiflora incarnata, Red clover (Trifolium pratense), and Glycine soja were effective in the treatment of acute menopausal syndrome with different mechanisms. Conclusion Medicinal plants can play an imperative role in the treatment of acute menopausal syndrome; however, further studies are required to buttress their efficacy in the treatment of acute menopausal syndrome.

    Menopause is described as a period of psychological difficulties that changes the lifestyle of women in multiple ways. Menopausal women require more information about their physical and psychosocial needs. Empowerment during the menopause can contribute to improving the perception of this stage and the importance of self-care. It is essential to increase women's awareness and adaptation to menopause, using empowerment programs. The aim of this study was to review the empowerment and coping strategies in menopause women. In this review, PubMed, EMBASE, ISI, and Iranian databases were scanned for relevant literature. A comprehensive search was performed, using the combinations of the keywords "empowerment, menopause, coping with" to review relevant literature and higher education journals. Most interventions for menopause women have focused on educational intervention, physical activity/exercise, healthy diet, stress management, healthy behaviors, preventing certain diseases and osteoporosis. Health education intervention strategy is one of the alternative strategies for improving women's attitudes and coping with menopause symptoms, identified as severalof the subcategories of health promotion programs. Empowerment of menopausal women will guarantee their health during the last third of their life. It will also help them benefit from their final years of reproductive life. The results of the present study can pave the way for future research about women's health promotion and empowerment.

    This study investigated the association between minor psychiatric disorders and menopause symptoms and their associated factors. A cross-sectional study was conducted with 615 women aged 40 to 65 years treated in a public menopause and gynecological outpatient clinic in the South Region of Brazil. Minor psychiatric disorders were assessed using the Self-Reporting Questionnaire (SRQ-20) and menopause symptoms using the Menopause Rating Scale. Score for menopause symptoms was categorized into three levels of symptoms: mild, moderate, and severe. Multivariate analyses used ordinal logistic regression. The prevalence of mild, moderate, and severe menopause symptoms was 34.1% (95% CI 30.3-37.9), 29.6% (95% CI 25.8-33.1), and 36.3% (95% CI 32.4-40.0), respectively. The overall prevalence of minor psychiatric disorders was 66.6% (95% CI 62.8-70.3). After adjustment, the odds ratio (OR) of the occurrence of menopause symptoms were approximately eight times higher in women relating minor psychiatric disorders compared with those without such disorders (OR = 7.76; 95% CI 5.27-11.44). The following factors were also associated with the menopause symptoms: women older than 50 years, living with a partner, lower educational level, smokers, larger number of pregnancies, obese, and those using psychotropic and/or postmenopause medication. The minor psychiatric disorders exhibited strong association with the presence of menopause symptoms independently of sociodemographic, behavioral, and reproductive factors, and of use of psychotropic medication.

    Negative parity rotational bands in {} 70160Yb{}90 nucleus have been studied. They were populated in the 148Sm(16O, 4n)160Yb reaction at 90 MeV. The gamma-coincidence data have been collected using Indian National Gamma Array composed of twenty Compton suppressed clover germanium (Ge) detectors. Double gating on triple gamma coincidence data were selectively used to develop the decay scheme for these negative parity bands by identifying and taking care of the multiplet transitions. The even- and odd-spin negative parity bands in 160Yb have been studied by comparing the reduced transition probability ratios with the similar bands in neighbouring even-even rare earth nuclei. It is concluded that the concerned odd-spin and even-spin bands are not signature partners and that their structures are compatible with those of the ‘pear-shape’ and ‘pyramid-shape’ oscillations, respectively, the octupole shapes superposed with the quadrupole shape of the ground-state.

    We use a consistent SU(6) extension of the meson-baryon chiral Lagrangian within a coupled channel unitary approach in order to calculate the T matrix for meson-baryon scattering in the s wave. The building blocks of the scheme are the π and N octets, the ρ nonet and the Δ decuplet. We identify poles in this unitary T matrix and interpret them as resonances. We study here the nonexotic sectors with strangeness S=0, -1, -2, -3 and spin J=(1/2), (3/2) and (5/2). Many of the poles generated can be associated with known N, Δ, Σ, Λ, Ξ and Ω resonances with negative parity. We show that most of the low-lying three and four star odd-parity baryon resonances with spin (1/2) and (3/2) can be related to multiplets of the spin-flavor symmetry group SU(6). This study allows us to predict the spin-parity of the Ξ(1620), Ξ(1690), Ξ(1950), Ξ(2250), Ω(2250) and Ω(2380) resonances, which have not been determined experimentally yet.

  18. [Phytoestrogens in the treatment of menopause].

    Remport, Júlia; Blázovics, Anna

    2017-08-01

    In previous centuries many women did not even live until their menopause years due to poor economic conditions, deficiencies of medicine, epidemics and wars. Nowadays in the developed countries, people live until they are 75-80 years old, and with the expansion of average age, the number of people affected by menopause and the years spent in that state increase. Nowadays women spend one third of their lives in the menopausal stage. The only effective way to treat unpleasant symptoms for centuries was with the use of herbs, and the knowledge about them spread through oral tradition. In the 20th century, this therapeutic form was pushed into the background by the development of synthetic drug production and the introduction of hormone replacement therapy. Thanks to the influence of media in the 20th century, women began to have the social need for preserving their beauty and youth for as long as they could. Hormone replacement therapy enjoyed great popularity because women were temporarily relieved of their life quality-impairing menopausal symptoms, but years later it turned out that hormone replacement therapy could pose serious risks. A distinct advantage of herbal therapy is the more advantageous side-effect-profile opposite the used synthetics in hormone replacement therapy. Women are therefore happy to turn to valuable and well-tried natural therapies, which have been used for thousands of years. There is growing interest in herbal remedies. Studying the effects of phytoestrogens has now become an active area for research. However, the results of studies in animals and humans are controversial, some sources suggest that phytoestrogens are effective and safe, other authors claim that they are ineffective in menopause or they have particularly dangerous properties, and cannot be recommended to everyone. It is important to address this issue for the sake of health, mental health and safety of women, and so it is necessary to assess the benefits and the risks

    In this Letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED 3 frequently claimed in the literature. As long as perturbative quantum field theory is concerned, whether a parity anomaly owing to radiative corrections exists or not shall be definitely proved by using a renormalization method independent of any regularization scheme. Such a problem has been investigated in the framework of BPHZL renormalization method, by adopting the Lowenstein-Zimmermann subtraction scheme. The 1-loop parity-odd contribution to the vacuum-polarization tensor is explicitly computed in the framework of the BPHZL renormalization method. It is shown that a Chern-Simons term is generated at that order induced through the infrared subtractions - which violate parity. We show then that, what is called 'parity anomaly', is in fact a parity-odd counterterm needed for restauring parity.

    In addition to inhibiting coronary atherosclerosis, estrogen is expected to have protective effects on cardiac myocytes. We investigated the difference in myocardial functional parameters evaluated by gated myocardial SPECT after adenosine-stress between post-menopausal and pre-menopausal healthy women. This study included 22 healthy post-menopausal women (mean age: 53.0 yr) and 20 pre-menopausal women (mean age: 43.0 yr) who performed Tc-99m tetrofosmin gated myocardial SPECT after adenosine-stress. Measured hemodynamic parameters, EDV, ESV, stroke volume, EF, cardiac output and cardiac index were compared between the two groups. For comparison, similar-aged two male groups with matched numbers were also studied. There was no significant difference in hemodynamic parameters. EDV, ESV, stroke volume, EF, or cardiac output between the post-menopausal and pre-menopausal women. However, post-menopausal women have a smaller cardiac index (mean: 1.95 L/min/m2 vs 2.20 L/min/m2; p=0.045) and adenosine-induced HR increase (mean : 80.5/min vs 89.7/min ; p=0.03), compared to the pre-menopausal women. On the contrary, the two male groups of the same age range and numbers with the women groups showed no significant difference in any myocardial parameters. These results suggest that menopause may be correlated with reduced increase in cardiac index and HR increase after adenosine-stress

    We explore the possibility to generate new parity symmetry in the quantum Rabi model after a bias is introduced. In contrast to a mathematical treatment in a previous publication [J. Phys. A 46 (2013) 265302], we consider a physically realistic method by involving an additional spin into the quantum Rabi model to couple with the original spin by an Ising interaction, and then the parity symmetry is broken as well as the scaling behavior of the ground state by introducing a bias. The rule can be found that the parity symmetry is broken by introducing a bias and then restored by adding new degrees of freedom. Experimental feasibility of realizing the models under discussion is investigated. (paper)

    Full Text Available The last decade has brought many challenges and uncertainties regarding the use of menopausal hormone therapy in women. Two early key studies, the Heart and Estrogen/Progestin Replacement Study (HERS and the Women's Health Initiative (WHI failed to prove beneficial effects of exogenous estrogen, and estrogen combined with progestin, in cardiovascular prevention. More recent studies, however, introduced the concept of a possible “window-of-opportunity” for hormonal therapy, in which menopausal hormone therapy is used early after the onset of menopause, and may lead to more favorable, cardio-protective outcomes. Despite the increasing wealth of clinical data, menopausal hormone therapy is not currently recommended for primary or secondary prevention of coronary heart disease in women. Further research is needed to understand the risk-benefit balance of menopausal hormone therapy. Resumen: La última década ha traído muchos retos e incertidumbres respecto al uso de la terapia hormonal en la menopausia en mujeres. Dos estudios tempranos clave, el Heart and Estrogen/Progestin Replacement Study (HERS [Estudio del Corazón y Reemplazo de Estrógeno/Progestina] y la Womeńs Health Initiative (WHI [Iniciativa de Salud de la Mujer] no pudieron demostrar los efectos benéficos del estrógeno exógeno y el estrógeno combinado con la progestina, en la prevención cardiovascular. Sin embargo, estudios más recientes han introducido el concepto de una posible “ventana de oportunidad” para la terapia hormonal, en donde la terapia hormonal en la menopausia se emplea tempranamente luego del inicio de la menopausia, y que puede llevar a resultados más favorables y cardioprotectores. A pesar de la creciente riqueza en datos clínicos, en la actualidad no se recomienda la terapia hormonal en la menopausia para la prevención primaria o secundaria de la enfermedad coronaria en mujeres.

    Can the diagnosis of common diseases before menopause influence age at natural menopause (ANM) onset? Polycystic ovary syndrome (PCOS) and depression were observed to delay menopause. It has been observed that women who undergo early menopause experience a higher burden of health problems related to metabolic syndromes, heart disease and depression, but whether ANM can be influenced by common adult diseases has not been studied extensively. All women attending mammography screening or clinical mammography at four hospitals in Sweden were invited to participate in the Karolinska Mammography Project for Risk Prediction of Breast Cancer (KARMA) study. Between January 2011 and March 2013, 70 877 women were recruited. Information from the baseline questionnaire filled out upon enrollment was used in this cross-sectional analysis on predictors of ANM onset. We limited our analyses to 61 936 women with complete data on ANM and covariates and a follow-up time (from birth to menopause or censoring) of at least 35 years. Premenopausal diagnoses of depression, anorexia, bulimia, PCOS, ovarian cyst, heart failure, myocardial infarction, angina pectoris, stroke, preeclampsia, diabetes, hypertension and hyperlipidemia were examined as time-dependent variables in multivariable Cox regression analyses, adjusting for reproductive factors (age at menarche, menstrual cycle regularity in adult life, number of children and premenopausal oral contraceptive use) and risk factors of common diseases (education, physical activity at 18 years and information at the time of questionnaire including BMI, ever smoking and alcohol consumption). Women with PCOS and depression were independently associated with later menopause (hazard ratio (95% CI): 0.44 (0.28-0.71) and 0.95 (0.91-1.00), respectively), compared to women with no such histories. The associations remained significant in a subset of women who had never received gynecological surgery or hormone treatment (n = 32313, 0.21 (0

    Increases in abdominal fat have been reported with menopause, but the impact of menopause on abdominal fat distribution (visceral vs subcutaneous) is still unclear. The objective of the study was to determine if abdominal fat content (volume) or distribution is altered with menopause. Magnetic resonance imaging was used to quantify total abdominal, subcutaneous, and visceral fat in 8 healthy women, both in the premenopausal state and 8 years later in the postmenopausal state. Physical activity (PA) and blood lipids were also measured. Body weight and waist circumference did not change with menopause (pre- vs postmenopause: body weight, 63.2 +/- 3.1 vs 63.9 +/- 2.5 kg; waist circumference, 92.1 +/- 4.6 vs 93.4 +/- 3.7 cm); however, total abdominal fat, subcutaneous fat, and visceral fat all significantly (P fat distribution was not significantly different after menopause (pre- vs postmenopause: subcutaneous, 73% +/- 3% vs 71% +/- 3%; visceral, 26% +/- 3% vs 28% +/- 3%). Lean mass, fat mass, and PA, along with total cholesterol and triglyceride levels, did not change with menopause. High-density lipoprotein and low-density lipoprotein both increased (P abdominal fat content increased with menopause despite no change in PA, body weight, or waist circumference; however, menopause did not affect the relative abdominal fat distribution in these women.

    Background: Sexual instinct which is the cause of numerous changes in an individual’s life could be influenced by different factors such as menopause and ageing. This study was designed to compare sexual dysfunction before and after menopause. Materials and Methods: This was a cross-sectional study. Participants were 174 menopausal women who referred to medical health centers of Isfahan, Iran. Data were collected through self constructed sexual dysfunctions questionnaire in relation to their sexual activities before and after menopause. The reliability and validity of this questionnaire was determined by content validity and Cronbach’s alpha coefficient. Findings: Findings showed that the relative frequency of sexual dysfunctions was 38% in the productive period and 72.4% in the menopause period. There was a significant association between sexual dysfunctions before and after the menopause period (p vaginismus, respectively. Conclusions: A considerable percentage of women experienced sexual dysfunctions in productive and menopause periods, and menopause could be a factor to maintain or intensify sexual dysfunctions.

  16. Parity violation in polarized electron scattering

    Prescott, C.Y.

    The weak forces are responsible for the decay of radioactive nuclei, and it was in these decay processes where parity non-conservation was first observed. Beta decay occurs through emission of e + or e - particles, indicating that the weak force can carry charge of both signs, and it was natural to speculate on the existence of a neutral component of the weak force. Even though weak neutral forces had not been observed it was conjectured that a neutral component of weak decay could exist, and Zel'dovich in 1957 suggested that parity violating effects may be observable in electron scattering and in atomic spectra. More than twenty years have passed since the early conjectures, and a great deal has been learned. Progress in quantum field theory led to the development of the SU(2) x U(1) gauge theory of weak and electromagnetic interactions and provided a renormalizable theory with a minimum of additional assumptions. Gauge theories predicted the existence of a new force, the neutral current interaction. This new interaction was first seen in 1973 in the Gargamelle bubble chamber at CERN. Today the neutral currents are accepted as well established, and it is the details of the neutral current structure that occupy attention. In particular the role that electrons play cannot be tested readily in neutrino beams (recent neutrino-electron scattering experiments are, however, rapidly improving this situation) and therefore interest in electron-hadron neutral current effects has been high. Parity violation is a unique signature of weak currents, and measurements of its size are a particularly important and sensitive means for determining the neutral current structure

  17. New parity, same old attitude towards psychotherapy?

    Full parity of health insurance benefits for treatment of mental illness, including substance use disorders, is a major achievement. However, the newly-published regulations implementing the legislation strongly endorse aggressive managed care as a way of containing costs for the new equality of coverage. Reductions in "very long episodes of out-patient care," hospitalization, and provider fees, along with increased utilization, are singled out as achievements of managed care. Medical appropriateness as defined by expert medical panels is to be the basis of authorizing care, though clinicians are familiar with a history of insurance companies' application of "medical necessity" to their own advantage. The regulations do not single out psychotherapy for attention, but long-term psychotherapy geared to the needs of each patient appears to be at risk. The author recommends that the mental health professions strongly advocate for the growing evidence base for psychotherapy including long-term therapy for complex mental disorders; respect for the structure and process of psychotherapy individualized to patients' needs; awareness of the costs of aggressive managed care in terms of money, time, administrative burden, and interference with the therapy; and recognition of the extensive training and experience required to provide psychotherapy as well as the stresses and demands of the work. Parity in out-of-network benefits could lead to aggressive management of care given by non-network practitioners. Since a large percentage of psychiatrists and other mental health professionals stay out of networks, implementation of parity for out-of-network providers will have to be done in a way that respects the conditions under which they would be willing and able to provide services, especially psychotherapy, to insured patients. The shortage of psychiatrists makes this an important access issue for the insured population in need of care.

    The development of experiments to detect parity nonconserving (PNC) mixing of the 2s/sub a/2/ and 2p/sub 1/2/ levels of the hydrogen atom in a 570 Gauss magnetic field is described. The technique involves observation of an asymmetry in the rate of microwave induced transitions at 1608 MHz due to the interference of two amplitudes, one produced by applied microwave and static electric fields and the other produced by an applied microwave field and the 2s/sub 1/2/-2p/sub 1/2/ mixing inducd by a PNC Hamiltonian

    In the 1970s the Walecka model and the chiral Walecka model were developed and have since been studied intensively. It was noted early on, however, that the chiral model leads to massless Lee-Wick nuclear matter in the chirally restored phase. A promising variant to describe nuclear matter and chiral symmetry restoration consistently is the parity doublet model (or mirror model). It has already been treated in a mean field (MF) approach with promising results. This is motivation for us to to examine this model with functional renormalization group (FRG) methods, hence including full mesonic fluctuations.

    We discuss parity violating asymmetries between the scattering of right and left-handed electrons on a variety of targets. Implications for gauge theories from recent SLAC results on deep-inelastic electron-deuterium and electron-proton scattering are examined. A derivation of the asymmetry for electron-electron scattering is given, its advantages are pointed out, and the feasibility of such a measurement is discussed. Other proposed or contemplated asymmetry experiments are reviewed and the necessity of including the Collins-Wilczek-Zee hadronic axial isoscalar current contribution in asymmetry predictions is noted

    The costs associated with reproduction (i.e., gestation, lactation, childcare) have long-term negative consequences by elevating risk of disease and reducing lifespan. We tested the hypotheses that high parity, and thus high reproductive costs bear by women, is perceived by other people when they evaluate facial appearance of health, attractiveness and age of mothers. Using computer software we created average facial images based on real photographs of post-menopausal women with varying number of children; 3 parity categories were created (1-2, 4-5, and 7-9 children). Study participants (N = 571) were asked to choose the face they perceived as more attractive, younger and healthier via two-alternative forced choice questions asked in three randomized blocks. Women who had given birth to fewer children were judged both by men and women as more attractive, younger and healthier than women with more children. In each category the lowest scores were received by women from highest parity category (7-9 children). Mechanisms behind the observed variation in facial appearance are not known but higher levels of oxidative stress among women with high parity may explain their faster aging and lower attractiveness in older age. These results suggest that costs of reproduction might affect women's physical appearance. © 2017 Wiley Periodicals, Inc.

    To evaluate the association between surgical menopause (SM) versus natural menopause (NM) in relation to later left ventricular (LV) structure and function, while taking into account the LV parameters and other cardiovascular disease risk factor (CVDRF) levels that predate the menopausal transition. We studied 825 premenopausal women from the Coronary Artery Risk Development in Young Adults study in 1990 to 1991 (baseline, mean age 32 years) who later reached menopause by 2010 to 2011 and had echocardiograms at these two time points. During 20 years of follow-up, 508 women reached NM, whereas 317 underwent SM (34% had bilateral oophorectomy). At baseline, women who later underwent SM were more likely to be black, younger, have greater parity, and higher mean values of systolic blood pressure, body mass index, and also lower mean high-density lipoprotein cholesterol and physical activity than women who reached NM. No significant differences in LV structure/function were found between groups. In 2010 to 2011, SM women had significantly higher LV mass, LV mass/volume ratio, E/e' ratio, and impaired longitudinal and circumferential strain than NM women. SM women with bilateral oophorectomy had adverse LV measures than women with hysterectomy with ovarian conservation. Controlling for baseline echocardiographic parameters and CVDRF in linear regression models eliminated these differences between groups. Further adjustment for age at menopause/surgery and hormone therapy use did not change these results. In this study, the adverse LV structure and function observed among women with SM compared with NM were explained by their unfavorable presurgical CVDRF profiles, suggesting that premenopausal CVDRF rather than gynecologic surgery predispose SM women to elevated future cardiovascular disease risk.

    We show that the introduction of massless fermions in an abelian gauge theory in 2+1 dimensions does not lead to any parity anomaly despite a non-commutativity of limits in the structure function of the odd part of the vacuum polarization tensor. However, parity anomaly does exist in non-abelian theories due to a conflict between gauge invariance under large gauge transformations and the parity symmetry. 6 refs

    In Mexico, calcaneal ultrasound measurements -bone mineral density (BMD), broadband ultrasound attenuation (BUA), speed of sound (SOS), ultrasonic quantitative index (QUI)- and their differences in regards to menopause have not been documented. It was carried out a cross-sectional study in 862 women from 20 to 90 years old, incorporated through consecutive sample, who were users of the Sistema para el Desarrollo Integral de la Familia (DIF) in Morelos. Sociodemographic, reproductive and life style factors were identified. BMD, BUA, SOS and QUI were measured with quantitative ultrasound (QUS), using a Sunlight Omnisense 7000 S device. Adjusted differences in the mean of these measurements were estimated between pre and postmenopausal women through multiple linear regression. The medians were: BMD, 0.455 g/cm² (IQR, interquartile range = 0.378, 0.538); BUA, 66.0 dB/mHz (IQR = 54.3, 78.1); SOS, 1530.7 m/s (IQR = 1509.8, 1551.7); QUI = 83.7 units (IQR = 71.1, 96.6). In postmenopausal women, adjusted mean for BUA was -4.34 dB/mHz (CI 95 % = -8.23,-0.43); for SOS, -4.26 m/s (CI 95 % = -13.82, 5.30) ; for QUI, -4.42 units (CI 95 % = -8.64,-0.19). This report increases information about the clinical applicability of QUS. SOS in calcaneus does not reflect changes related with menopause.

    The concept of genitourinary syndrome of menopause (GSM) was recently introduced and has been gaining widespread use. While some justifications for its introduction are straightforward, others may be questionable. Numerous unspecific symptoms and signs were included in the definition of the syndrome, but the minimum number required for diagnosis was not established. While the GSM definition is designed to facilitate identifying vulvovaginal and urinary estrogen-deprivation-associated symptoms and signs, several concerns have evolved: (1) the syndrome may result in the underdiagnosis of vulvar and urinary pathology; and (2) serious conditions (e.g., high-grade squamous intraepithelial lesions of the vulva or vulvar intraepithelial neoplasia, differentiated type) may be missed while others may not receive appropriate treatment (e.g., lichen sclerosus, overactive bladder). In addition, the transformation of urogenital symptoms and signs into a syndrome may create an iatrogenization of menopause, which, consequently, can lead to demand for (and offer of) a panacea of treatments. This can be detrimental to the care of women who require focused therapy rather than global treatment addressing a variety of genitourinary conditions, not all of which even require any form of intervention. Women's needs may be better served by having a more precise urogenital diagnosis.

    The purpose of this cross-sectional study was to assess the association of the menopausal transition with changes in vitamins. The study group comprised women aged 17-85 years from the Third National Health and Nutrition Examination Survey (NHANES), which was conducted between 1988 and 1994, and from the NHANES surveys conducted between 1999 and 2006. Menopausal status was defined using the time since the last period, 12 months, for the pre-, peri-, and postmenopause, respectively. The data-cleaning technique employing serum follicle stimulating hormone activity resulted in pre-, peri- and postmenopausal samples encompassing the following age brackets: 17-50, 42-51, and 46-85 years. Statistical inferences were analyzed using non-parametric techniques. Significant increases in vitamin A and vitamin E concentrations across all phases of the menopausal transition were observed. There was a gradual decrease in the vitamin C concentration across all stages of the menopause but a fairly stable concentration of vitamin B12. There was a statistically significant increase in vitamin D between the pre- and postmenopause. Body mass index correlated negatively with serum vitamin concentration in the pre- and postmenopause. Vitamin A should be supplemented in postmenopausal women to decrease the risk of bone fracture. The daily diet should be supplemented with vitamin B12, to avoid possible neurological symptoms due to vitamin B12 deficiency, and with vitamin D to decrease the risk of developing secondary hyperparathyroidism. Due to an adverse influence on serum vitamin concentration, body mass index should be monitored in pre- and postmenopausal women.

    Because the experience of menopause varies by ethnic group, society, and social class, we sought to compare quality of life (QoL) at menopause between Tunisian and French women. This secondary analysis of existing data collected in two independent, cross-sectional surveys (the French GAZEL cohort and a representative sample of Tunisian women) compared both samples for six dimensions of the Women's Health Questionnaire while taking into account social and demographic characteristics and menopause status with multivariate logistic models. Comparison of 1,040 Tunisian women aged 45 to 64 years with 774 French women aged 48 to 53 years showed that Tunisian women had a significantly lower QoL than the French women in every dimension (low QoL for Tunisian vs French, odds ratio [95% CI]: somatic symptoms, 2.1 [1.6-2.7]; depressed mood, 3.6 [2.8-4.7]; anxiety, 2.4 [1.8-3.3]; vasomotor symptoms, 1.7 [1.3-2.3]). QoL was also lower for working-class women, but associations were weaker than for country (low QoL for working class vs middle class, odds ratio [95% CI]: somatic symptoms: 1.9 [1.5-2.4]; depressed mood, 1.5 [1.2-1.8]; anxiety, 1.8 [1.5-2.3]; vasomotor symptoms, 1.7 [1.4-2.2]). Associations between country and QoL were stronger in the working class than in the middle class. This epidemiological study comparing France and a North African country sheds light on the major role of country of residence, social class, and their interaction in the experience of menopause. Levels of national wealth, human development, cultural constraints, and social and gender inequality are likely to explain how country and class affect QoL.

  8. Κ-meson decays and parity violation

    Between 1948 and 1954 many Κ-meson decay modes were observed, including the tau, pion and xi positives, in emulsion experiments all with masses around 500 MeV. An attempt was made to rationalize the various names for the new particles being discovered. A period of experimental consolidation followed. An attempt was then made to determine the spin parity of the three-pion system from tau plus decay using matrix calculations. New stripped emulsion techniques now permitted a secondary-particle track to be followed to its endpoint. Stacked emulsions were flown in balloons to study Κ mesons and hyperons using cosmic radiation. Later similar work used the new particle accelerators, the Cosmotron and the Bevatron as sources. The author showed that the tau plus and theta plus were competing decay modes of the same Κ + meson, but this meant that parity conservation was violated. Later theoreticians T D Lee and C N Yang provided evidence for this surprising idea from their work on semileptonic weak interactions. (UK)

    This study aims to estimate the prevalence and predictors of moderate/severe poor sleep in relation to the final menstrual period (FMP) in midlife women. Annual assessments were conducted in a population-based cohort of 255 women. All were premenopausal at cohort enrollment and reached natural menopause during the 16-year follow-up. The outcome measure was severity of poor sleep, as reported by participants in annual interviews for 16 years and as evaluated in relation to the FMP. The annual prevalence of moderate/severe poor sleep largely ranged from about 28% to 35%, with no significant differences in any year relative to the FMP for the sample overall. When sleep status was stratified at premenopausal baseline, premenopausal sleep status strongly predicted poor sleep around the FMP. Women with moderate/severe poor sleep in premenopause were approximately 3.5 times more likely to have moderate/severe poor sleep around menopause than those with no poor sleep at baseline in adjusted analysis (odds ratio, 3.58; 95% CI, 2.50-5.11; P menopause (odds ratio, 1.57; 95% CI, 0.99-2.47; P = 0.053). There was no significant association between poor sleep and time relative to the FMP among women who had no poor sleep at premenopausal baseline. Hot flashes were significantly associated with poor sleep (odds ratio, 1.79; 95% CI, 1.44-2.21; P menopausal transition. Overall, poor sleep does not increase around the FMP and frequently occurs in the absence of hot flashes, indicating that sleep difficulties in the menopausal transition in generally healthy women are not simply associated with ovarian decline.

    We aimed to investigate the change in prevalence of overweight and obesity in pregnant Danish women from 2004 to 2012, and investigate whether increasing parity was associated with a change in body mass index (BMI) prevalence. We obtained a population-based cohort from the Danish Medical Birth Registry consisting of all Danish women giving birth in 2004-2012 (n = 572 321). This registry contains information on 99.8% of all births in Denmark. We calculated the overall change in prepregnancy BMI status among pregnant women in Denmark, and a multiple linear regression model with adjustment for several potential confounders was used to examine the change in prepregnancy BMI with increasing parity. In 2004, the prevalence of prepregnancy overweight and obesity (BMI ≥ 25) and obesity alone (BMI ≥ 30) was 31.9 and 11%, respectively. In 2012, the prevalence had reached 34.2 and 12.8%. The mean BMI increased for every additional parity from 23.80 (95% CI 23.77-23.82) in parity group 1 to 26.70 (26.52-26.90) in parity group 5+. A multiple linear regression adjusted for potential confounders showed that women on average gained 0.62 (0.58-0.65) BMI units after every additional birth. This study showed a 7.2% increase in overweight and obesity (BMI ≥ 25) and a 16.4% increase in obesity alone (BMI ≥ 30) for pregnant women in Denmark from 2004 to 2012. In addition, an increase in interpregnancy BMI was seen at every additional delivery, suggesting that obesity is an increasing challenge in obstetrics. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

    The menopausal transition is associated with somatic symptoms and increased rates of depression, which can impair quality of life (QOL) and increase cardiovascular disease (CVD) risk. This period is also associated with accelerated vascular aging (arterial stiffening and endothelial dysfunction), an antecedent to CVD. This secondary analysis sought to explore associations between depression, menopausal symptoms and QOL, and vascular aging across menopause stages. Arterial stiffness (carotid artery compliance), endothelial function (brachial artery flow-mediated dilation [FMD]), menopausal symptoms (Menopausal Symptom List [MSL]), depression (Center for Epidemiologic Studies Depression Scale [CES-D]), and QOL (Utian QOL Scale [UQOL]) were measured in 138 women (19-70 years) classified as premenopausal (n = 41, 34 ± 8 years; mean ± SD), early (n = 25, 49 ± 3 years), or late perimenopausal (n = 26, 50 ± 4 years), or early (n = 22, 55 ± 4 years) or late postmenopausal (n = 24, 61 ± 5 years). Differences across menopause stages were determined using one-way analysis of variance; associations between vascular measures and MSL, CES-D, and UQOL were tested using Pearson's correlation analyses. Menopausal symptoms, depression, and QOL worsened across menopause stages, particularly in late perimenopausal women. Vasosomatic symptom frequency, and general somatic symptom frequency and severity were inversely correlated with carotid artery compliance and FMD (r = -0.27 to -0.18, all P stages of menopause was associated with greater frequency and severity of menopausal symptoms, and lower QOL, but not depression. Mechanisms underlying these associations (eg, inflammation, oxidative stress) should be explored.

    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.

    Osteoporosis and osteopenia among postmenopausal Saudi Arabian women are common to the extent of over 60%. Pregnancy, multiparity and prolonged lactation are suggested as factors modifying negatively in the development of osteoporosis. Earlier reports from the institution indicated a beneficial role of multiparity in postmenopausal osteoporosis (PMO). We conducted this study to measure the effect of parity on bone mineral density (BMD) measurement of lumbar spine and the upper femur. We conducted this prospective study at King Fahd Hospital of the University, College of Medicine, King Faisal University, Dammam, Saudi Arabia, between January 2002 and June 2003. This study analyzed 256 patients who attended orthopedic clinics. The data gathered was age, duration of menopause, number of children borne, height and weight for body mass index (BMI) calculation. We excluded women with secondary osteoporosis from the study. We entered the patients orthopedic complaints in the database. We carried out the BMD measurements using Hologic total body DEXA machine. We analyzed the data using SPSS package with significance at p6 children and group B with women of 6 children, 25.4% were osteoporotic in group A and in group B 48%. As per the World Health Organization classification 56% in group A had an increased risk of fracture as compared to 77.5% in group B women. Our results indicate that women who had borne >6 children were less osteoporotic and of low fracture risk as compared to those women who had 6 children was statistically higher than their counterparts, and they sustain this after prolonged lactation. We believe that increased parity protects women from osteoporosis and the severity of the disease, and it is our suggestion that women with osteoporosis should be investigated and treated accordingly.

    Patterns of symptom clustering in midlife women may suggest common underlying mechanisms or may identify women at risk of adverse health outcomes or, conversely, likely to experience healthy aging. This paper assesses symptom clustering in the Study of Women's Health Across the Nation (SWAN) longitudinally by stage of reproductive aging and estimates the probability of women experiencing specific symptom clusters. We also evaluate factors that influence the likelihood of specific symptom clusters and assess whether symptom clustering is associated with women's self-reported health status. This analysis includes 3289 participants in the multiethnic SWAN cohort who provided information on 58 symptoms reflecting a broad range of physical, psychological and menopausal symptoms at baseline and 7 follow-up visits over 16 years. We conducted latent transition analyses to assess symptom clustering and to model symptomatology across the menopausal transition (pre, early peri-, late peri- and post-menopausal). Joint multinomial logistic regression models were used to identify demographic characteristics associated with premenopausal latent class membership. A partial proportional odds regression model was used to assess the association between latent class membership and self-reported health status. We identified six latent classes that ranged from highly symptomatic (LC1) across most measured symptoms, to moderately symptomatic across most measured symptoms (LC2), to moderately symptomatic for a subset of symptoms (vasomotor symptoms, pain, fatigue, sleep disturbances and physical health symptoms) (LC3 and LC5) with one class (LC3) including interference in life activities because of physical health symptoms, to numerous milder symptoms, dominated by fatigue and psychological symptoms (LC4), to relatively asymptomatic (LC6). In pre-menopause, 10% of women were classified in LC1, 16% in LC2, 14% in LC3 and LC4, 26% in LC5, and 20% in LC6. Intensity of vasomotor and

    We assessed changes in self-reported sexual activity (SA) over 13 years among HIV-infected and uninfected women. The impact of aging and menopause on SA and unprotected anal or vaginal intercourse (UAVI) was examined among women in the Women’s Interagency HIV Study (WIHS), stratifying by HIV status and detectable viral load among HIV-infected women. Generalized mixed linear models were fitted for each outcome, adjusted for relevant covariates. HIV-uninfected women evidenced higher levels of SA and UAVI than HIV-infected. The odds of SA declined by 62–64 % per decade of age. The odds of SA in a 6-month interval for women aged 40–57 declined by 18–22 % post-menopause (controlling for age). Among HIV+/detectable women only, the odds of any UAVI decreased by 17 % per decade of age; the odds of UAVI were unchanged pre-menopause, and then decreased by 28 % post-menopause. Elucidating the factors accounting for ongoing unprotected sex among older women should inform interventions. PMID:25245474

    Hormone replacement therapy (HRT) remains the gold standard for the management of menopausal symptoms; however, HRT use has declined due to concerns over possible adverse side-effects. Approaches to menopause management are continually being revised and these extend beyond the control of recognized menopausal symptoms to encompass wider aspects of menopausal women's health. Hypertension and associated cardiovascular risk are particularly important unmet needs in postmenopausal women, especially in the Asia-Pacific region which has a rapidly aging population and bears around half of the global burden of cardiovascular disease, two-thirds of which has been attributed to elevated blood pressure. As first point of contact for women with menopausal symptoms, gynecologists play a gatekeeper role in assessing women's health, providing appropriate lifestyle counseling, and, where appropriate, implementing treatment or referral to relevant specialists. This paper, with contributions by gynecologists and cardiologists from Asia Pacific and beyond, summarizes available evidence and provides a treatment algorithm that employs a flexible blood pressure classification strategy to assist physicians in their decision-making for the individualized management of menopausal symptoms in women with low, moderate and high cardiovascular risk, and also for women with diabetes. Individualized HRT according to cardiovascular risk may yield improvements in cardiovascular health, as well as managing menopausal symptoms.

    Full Text Available The menopause is characterized by a reduction in ovarian function and estrogen production. Altogether, these changes together lead to a series of disorders that may affect the woman’s life style. Currently, medicine, influenced by the pharmaceutical industry, is prone to act aggressively against any symptoms, resulting in. polymedicated population. Doctors usually prescribe treatments such as hormone replacement therapy (HRT, to help them manage menopause symptoms. However, recently, several studies have reported adverse effects associated with this treatment. The influence of diet on several chronic diseases in western societies is currently well known. Therefore, dietary therapies, including dietary soy and isoflavone supplements, have been proposed for the reduction of menopause symptoms. Several published studies have suggested isoflavones, which have a great estrogenic power, as an HRT alternative for the relief of menopause symptoms. However, our current understanding on the effects of isoflavone supplements on the menopause symptoms is limited, and scientific publications show heterogenous results. Due to those arguments, the objective of this review is to address some of the mechanisms of isoflavones and their role in the menopausal period, postulating that, as food supplements, they could be used as a complementary therapy for menopause symptoms.

    This study aims to understand the current teaching of menopause medicine in American obstetrics and gynecology residency programs. A Web-based survey was e-mailed to all American obstetrics and gynecology residency directors, with a request that they forward it to their residents. Of 258 residency program directors contacted, 79 (30.6%) confirmed forwarding the survey. In all, 1,799 people received the survey, with 510 completions, for a response rate of 28.3%. Most residents reported that they had limited knowledge and needed to learn more about these aspects of menopause medicine: pathophysiology of menopause symptoms (67.1%), hormone therapy (68.1%), nonhormone therapy (79.0%), bone health (66.1%), cardiovascular disease (71.7%), and metabolic syndrome (69.5%). Among fourth-year residents who will be entering clinical practice soon, a large proportion also reported a need to learn more in these areas: pathophysiology of menopause symptoms (45.9%), hormone therapy (54.2%), nonhormone therapy (69.4%), bone health (54.2%), cardiovascular disease (64.3%), and metabolic syndrome (63.8%). When asked to rate the most preferred modalities for learning about menopause, the top choice was supervised clinics (53.2%), followed by case presentations (22.2%), formal lectures (21.3%), small groups (14.7%), Web-based learning (7.8%), and independent reading (5.2%). Only 20.8% of residents reported that their program had a formal menopause medicine learning curriculum, and 16.3% had a defined menopause clinic as part of their residency. It seems that some American residency programs do not fulfill the educational goals of their residents in menopause medicine. A curriculum would be beneficial for increasing knowledge and clinical experience on menopause issues.

    Germline mutations in BRCA1 and BRCA2 (BRCA1/2) are related to an increased lifetime risk of developing breast and ovarian cancer. Although risk-reducing salpingo-oophorectomy reduces the risk of both cancers, loss of fertility is a major concern. A recent study suggested an association between BRCA1 mutation and occult primary ovarian insufficiency. The objective of the current study was to determine whether BRCA1/2 mutation carriers have an earlier onset of natural menopause compared with unaffected women. White carriers of the BRCA1/2 gene (n = 382) were identified within the Breast Cancer Risk Program Registry at the University of California at San Francisco and compared with non-clinic-based white women in northern California (n = 765). The 2 groups were compared with regard to median age at the time of natural menopause before and after adjustment for known risk factors, and the role of smoking within each group was examined using the Kaplan-Meier approach for unadjusted analyses and Cox proportional hazards regression analyses for adjusted analyses. The median age at the time of natural menopause in the BRCA1/2 carriers was significantly younger than among the unaffected sample (50 years vs 53 years; P < .001). The unadjusted hazard ratio for natural menopause when comparing BRCA1/2 carriers with unaffected women was 4.06 (95% confidence interval, 3.03-5.45) and was 3.98 (95% confidence interval, 2.87-5.53) after adjusting for smoking, parity, and oral contraceptive use. For BRCA1/2 carriers who were current heavy smokers (smoking ≥ 20 cigarettes/day), the median age at natural menopause was 46 years versus 49 years for nonsmokers (P = .027). The BRCA1/2 mutation was associated with a significantly earlier age at natural menopause, and heavy smoking compounded this risk. Because the relationship between menopause and the end of natural fertility is considered to be fixed, these findings suggest the risk of earlier infertility among BRCA1/2 carriers

    In menopause transition many women have vasomotor symptoms which may affect their normal daily activities. With the decline in oestrogen levels, risk factors for coronary heart disease (CHD) become more apparent, especially hypertension. The onset of hypertension can cause a variety of complaints that are often attributed to the menopause. Risk factor identification is poorly managed in middle-aged women and should be the first step in the evaluation and treatment of women with perimenopausal symptoms. In women at low risk for CHD, there is still a window of opportunity for safe hormone prescription in the first years proximal to menopause. (Neth Heart J 2009;17:68-72.).

    Evidence shows than an estimated one billion women have experienced menopause worldwide. The experience of menopause is influenced by beliefs and values prevalent in the sociocultural setting, the background of the women, and the ways in which the women approach changes in this phase of life. Independently of the circumstances involved, women experiencing menopause need to have their care needs and corresponding support identified based on their personal and contextual perspectives. Although it is essential to provide appropriate support to women experiencing menopause, no systematic reviews have so far been conducted that focus on menopause experienced by women worldwide. The objective of this review is to identify the best available evidence related to how women experience menopause worldwide. This review considered studies that included menopausal women aged between 40 and 65 years, who have lived the transition from reproductive years through menopause and beyond. This review included only studies whose participants have lived the experience of natural menopause. Women who have had induced menopause, or with premature menopause were excluded from this review. TYPES OF INTERVENTION(S)/PHENOMENA OF INTEREST: This review considered studies that investigate women's experiences of natural menopause under the scope of different social and cultural settings. TYPES OF STUDIES: This review considered studies that have a descriptive and interpretive approach, conducted using qualitative methodology. Qualitative studies that focus on program evaluation were excluded from this review. Qualitative data including, but not limited to, study designs such as phenomenology, grounded theory, ethnography, action research and feminist research were considered for inclusion in this review. TYPES OF OUTCOMES: This review considered studies that include the following outcome measures: all aspects related both directly and indirectly to the experience of menopause, as concretely lived

    The predictive values of plasma non-esterified fatty acid (NEFA), beta-hydroxybutyrate (BHB), cholesterol, albumin and calcium to predict risk of peripartum diseases in primiparous (PP) and multiparous (MP) Holstein cows was investigated. Besides it was assessed if the health status interacted with parity on body condition score and metabolic profiles during the transition period. Dairy cows (126 PP and 182 MP) from a commercial dairy free stall herd (loose-housing system) were weekly body condition scored and tail bled for metabolites determination from -3 to +4 weeks relative to calving. Peripartum diseases were diagnosed by a single trained veterinarian, while subclinical diseases (ketosis and hypocalcemia) were diagnosed at the laboratory. Cows were classified as healthy cows, cows with one event, or cows with two clinical events following a prospective observational cohort study, with only healthy cows enrolled at the beginning of the study. The largest incidence was for metritis (26.6%) followed by retained placenta (17.2%) and mastitis (15.2%) with no effect of parity, while subclinical hypocalcemia incidence was greater in MP than PP cows (43% vs 9.5%) respectively. In MP cows albumin concentrations were predictive for metritis at week -2 and for retained placenta at weeks -2 and -1, while cholesterol was predictive for mastitis at week -2, -1 and at calving. The interaction between health status and parity affected all metabolites during the transition period. This study showed a different evolution of metabolic profiles in healthy and sick cows during the transition according to parity, pointing out albumin and cholesterol as diseases predictors before calving.

    The (J , T) = (1 , 1) parity doublet in 20Ne at 11.26 MeV is a good candidate to study parity violation in nuclei. However, its energy splitting is known with insufficient accuracy for quantitative estimates of parity violating effects. To improve on this unsatisfactory situation, nuclear resonance fluorescence experiments using linearly and circularly polarized γ-ray beams were used to determine the energy difference of the parity doublet ΔE = E (1-) - E (1+) = - 3.2(± 0.7) stat(-1.2+0.6)sys keV and the ratio of their integrated cross sections Is,0(+) /Is,0(-) = 29(± 3) stat(-7+14)sys. Shell-model calculations predict a parity-violating matrix element having a value in the range 0.46-0.83 eV for the parity doublet. The small energy difference of the parity doublet makes 20Ne an excellent candidate to study parity violation in nuclear excitations.

    In infinite nuclear matter with pion condensates or tensor binding both parity and isospin symmetries are broken. Finite nuclei with pion condensates or tensor binding, however, can have definite parity. They cannot have a definite value of isospin, whose average value is of the order of the number of nucleons.

    Gamma lines in the decay of I have been measured by means of a Ge(Li) detector. The following gamma ray energies have been obtained: 442.5 ± 0.05, 526.5 ± 0.5, 742.4 ±1.0, 969.0 ± 1.0, and 1136.5 ±2.0 keV. The 1136.5 keV transition defines a level in 128 Xe at 1579 ± 2 keV. From the log ft = 7.8 ± 0.3 of the (β - feeding, this level is believed to have an odd parity. Upper limits of gamma ray intensities for transitions around eV are used to set a limit for the population of the expected 0 + level originating from the two-phonon quadrupole vibration

    The effect of spontaneous breaking of chiral symmetry over the spectrum of highly excited hadrons is addressed in the framework of a microscopic chiral potential quark model (Generalised Nambu-Jona-Lasinio model) with a vectorial instantaneous quark kernel of a generic form. A heavy-light quark-antiquark bound system is considered, as an example, and the Lorentz nature of the effective light-quark potential is identified to be a pure Lorentz-scalar, for low-lying states in the spectrum, and to become a pure spatial Lorentz vector, for highly excited states. Consequently, the splitting between the partners in chiral doublets is demonstrated to decrease fast in the upper part of the spectrum so that neighboring states of an opposite parity become almost degenerate. A detailed microscopic picture of such a 'chiral symmetry restoration' in the spectrum of highly excited hadrons is drawn and the corresponding scale of restoration is estimated

    We reformulate the analysis of nuclear parity violation (PV) within the framework of effective field theory (EFT). To O(Q), the PV nucleon-nucleon (NN) interaction depends on five a priori unknown constants that parameterize the leading-order, short-range four-nucleon operators. When pions are included as explicit degrees of freedom, the potential contains additional medium- and long-range components parameterized by PV πNN coupling. We derive the form of the corresponding one- and two-pion-exchange potentials. We apply these considerations to a set of existing and prospective PV few-body measurements that may be used to determine the five independent low-energy constants relevant to the pionless EFT and the additional constants associated with dynamical pions. We also discuss the relationship between the conventional meson-exchange framework and the EFT formulation, and argue that the latter provides a more general and systematic basis for analyzing nuclear PV

    Time-Reversal-Invariance non-conservation has for the first time been unequivocally demonstrated in a direct measurement at CPLEAR. One then can ask the question: What about tests of time-reversal-invariance in systems other than the kaon system? Tests of time-reversal-invariance can be distinguished as belonging to two classes: the first one deals with time-reversal-invariance-non-conserving (T-odd)/parity violating (P-odd) interactions, while the second one deals with T-odd/P-even interactions (assuming CPT conservation this implies C-conjugation non-conservation). Limits on a T-odd/P-odd interaction follow from measurements of the electric dipole moment of the neutron (room for further experimentation?

    BACKGROUND: Half the epidemiological studies with information about menopausal hormone therapy and ovarian cancer risk remain unpublished, and some retrospective studies could have been biased by selective participation or recall. We aimed to assess with minimal bias the effects of hormone therapy...... on ovarian cancer risk. METHODS: Individual participant datasets from 52 epidemiological studies were analysed centrally. The principal analyses involved the prospective studies (with last hormone therapy use extrapolated forwards for up to 4 years). Sensitivity analyses included the retrospective studies....... Adjusted Poisson regressions yielded relative risks (RRs) versus never-use. FINDINGS: During prospective follow-up, 12 110 postmenopausal women, 55% (6601) of whom had used hormone therapy, developed ovarian cancer. Among women last recorded as current users, risk was increased even with

    Post-menopausal women are at significant risk for coronary artery disease, have increased rates of depression compared to their male counterparts, and often present atypically with coronary insufficiency. The symptoms of depression and coronary ischemia overlap greatly. Complaints like fatigue, body aches, and sleep disturbance reported by a depressed elderly woman may be cardiac related and need to be investigated seriously without physician bias. To ensure that clinicians are cautious when evaluating older women with a history of depression who are presenting with atypical complaints. A 61-year-old woman with history of depression presented to the Emergency Department with multiple complaints atypical for acute coronary syndrome. She had an immediate electrocardiogram and troponin-T Biosite point-of-care test (Biosite Incorporated, San Diego, CA) performed, which were positive for cardiac ischemia and myocardial infarction. The patient underwent immediate cardiac catheterization, which revealed occlusion of the mid left circumflex. After aspiration of thrombus and balloon dilatation of the site, a bare metal stent was deployed, restoring excellent flow. The patient did well medically but her depression worsened after the procedure and continues despite psychiatric intervention. For years there have been gender differences in medical treatment of coronary artery disease, and often women's complaints are not investigated aggressively. Post-menopausal women are at great risk for cardiac ischemia and depression, and their symptoms, which are often atypical, may not be diagnosed as anginal equivalents. In addition, depression is an independent risk factor for cardiovascular disease and, if it occurs after myocardial infarction, may lead to poor quality of life and increased morbidity and mortality. Patients who have had a coronary event must be thoroughly evaluated for signs of depression and receive the necessary treatment. Published by Elsevier Inc.

    Full Text Available While there has been a substantial decline in lead exposure in the United States during the past two decades, mobilization of existing lead stored in bone potentially represents an important endogenous source of exposure for menopausal women. It has been hypothesized that lead may be mobilized from skeletal stores during conditions of high bone turnover, such as during menopause. However, such mobilization has not been documented in prospective studies. This discussion is focussed on some of the methodological difficulties to be anticipated in longitudinal studies of lead mobilization specific to menopause and the issues that need to be taken into account when evaluating the results of such studies. To evaluate whether lead mobilization occurs during menopause, a prospective repeated measures design is needed using X-ray fluorescence analysis of lead in bone and serial measurements of blood lead. Potential confounders and effect modifiers also need to be taken into account in the statistical analysis.

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

    To document the common menopausal symptoms and quality of life in indigenous women of Sarawak in Malaysia. A face-to-face interview using the Menopause-specific Quality of Life questionnaire was conducted with 276 indigenous Sarawakian women aged 40-65 years to determine the mean age of menopause and common symptoms (divided into vasomotor, psychosocial, physical and sexual domains) associated with menopause. The mean age at menopause of postmenopausal women was 50.78 +/- 2.47 years (range 47.3-58.2 years). The most common symptoms reported were aching in muscles and joints (82.6%), lack of energy (77.5%) and low backache (77.2%). The typical menopausal symptoms of hot flushes, night sweats, sweating and vaginal dryness were experienced by 42.4%, 34.8%, 29.7% and 49.3%, respectively of the women studied. Perimenopausal women (n = 114) experienced the most physical and psychosocial symptoms, while postmenopausal women (n = 102) experienced most sexual symptoms. Perimenopausal and postmenopausal women were reported to suffer more than premenopausal women (p < 0.001) within the four domains of symptoms (vasomotor, psychosocial, physical and sexual). The menopausal symptoms in this study correspond to those in other studies on Asian women but the prevalence of typical and classical menopausal symptoms was lower compared to studies on Caucasian women. The perimenopausal women had the most significant decrease in quality of life, followed by postmenopausal women and premenopausal women. Vasomotor symptoms had a predominant influence on the quality of life.

    2011-01-01

    The effect of multiple pregnancies, a very common pattern in reproductive lifestyle of Pakistani women, needs to be addressed to see if it affects the iron content and hence cause iron deficiency. Recognising this deficiency prior to development of anaemia can prevent disastrous consequences that can complicate the life of the mother and foetus especially in developing countries. The objective of this study was to assess the effect that the stress of multiple pregnancies has on the iron status of the body. Methods: This comparative study was conducted in a focus group of female population. Two hundred subjects were selected by convenient sampling and grouped depending on their parity status. Data regarding diet, and socioeconomic history was collected on pre-designed questionnaire. Serum Ferritin was used to assess iron deficiency using the Electro chemiluminescence Immunoassay (ECLIA). Data was statistically analysed using SPSS-17. Results: Mean value of serum Ferritin in the nulliparous group was 76.52 +- 4.92 eta g/mL with 16% of nulliparous subjects showing lower than normal values. Thirty-six percent of uniparous subjects showed low serum Ferritin values, mean value being 45.74 +- 4.51 eta g/mL. Seventy-two percent of the multiparous subjects showed iron deficiency with Ferritin levels of <20 eta g/mL. Mean serum Ferritin in this group was 25.21+- 2.75 g/mL. The differences between the Ferritin levels of the study groups were highly significant (p<0.01). Conclusions: Multiparous women had lower serum Ferritin levels than the control group suggesting that the stress of multiple pregnancies takes its toll on the iron content of the body. (author)

    The rise in noncommunicable diseases and their risk factors in developing countries may have changed or intensified the effect of parity on obesity. We aimed to assess this association in Peruvian women using data from a nationally representative survey. We used data from Peru's Demographic and Health Survey, 2012. Parity was defined as the number of children ever born to a woman. We defined overweight as having a body mass index (BMI, kg/m 2 ) of 25.0 to 29.9 and obesity as a BMI ≥30.0. Generalized linear models were used to evaluate the association between parity and BMI and BMI categories, by area of residence and age, adjusting for confounders. Data from 16,082 women were analyzed. Mean parity was 2.25 (95% confidence interval [CI], 2.17-2.33) among rural women and 1.40 (95% CI, 1.36-1.43) among urban women. Mean BMI was 26.0 (standard deviation, 4.6). We found evidence of an association between parity and BMI, particularly in younger women; BMI was up to 4 units higher in rural areas and 2 units higher in urban areas. An association between parity and BMI categories was observed in rural areas as a gradient, being highest in younger women. We found a positive association between parity and overweight/obesity. This relationship was stronger in rural areas and among younger mothers.

    OBJECTIVE To examine the association between chronic medical conditions and reproducibility of self-reported age at menopause among community-dwelling women. METHOD Age at menopause was assessed in a population-based longitudinal survey of 240 women twice, in 1993 and 2004. Women who recalled age at menopause in 2004 within one year or less of the age at menopause recalled in 1993 (concordant) were compared with women who did not recall of age at menopause in 2004 within 1 year of age at menopause recalled in 1993 (discordant). Type of menopause (surgical or natural) and chronic medical conditions were assessed by self-report. RESULTS One hundred and forty three women (59.6%) reported surgical menopause and 97 (40.4%) reported natural menopause. In all, 130 (54.2%) of women recalled age at menopause in 2004 within one year or less of recalled age at menopause in 1994 while 110 (45.8%) women did not recall age at menopause in 2004 within one year or less of recalled age at menopause in 1994. Among women with surgical menopause, women with three or more medical conditions were less likely to have concordant recall of age at menopause than women with less than three chronic medical conditions (adjusted odds ratio (OR) = 0.36, 95% confidence interval (CI) [0.15, 0.91]) in multivariate models controlling for potentially influential characteristics including cognition and years from menopause. CONCLUSIONS Among women who underwent surgical menopause, the presence of three or more medical conditions is associated with decreased reproducibility of self-reported age at menopause.

    A document discusses a new parity pupil mask design that allows users to unambiguously determine the image space coordinate system of all the James Webb Space Telescope (JWST) science instruments by using two out-of-focus images. This is an improvement over existing mask designs that could not completely eliminate the coordinate system parity ambiguity at a wavelength of 5.6 microns. To mitigate the problem of how the presence of diffraction artifacts can obscure the pupil mask detail, this innovation has been created with specifically designed edge features so that the image space coordinate system parity can be determined in the presence of diffraction, even at long wavelengths.

    We propose a mechanism for parity violation in the two nucleon meson-exchange interaction by way of the mixing of mesons of opposite parities. This mixing arises from parity violating W ± and Z exchange between the q-antiq pari in the meson. Numerically is effect turns out to be as important as vector meson exchange with a weak meson-nucleon vertex. The calculation is performed using both the standard Born approximation adding the amplitude phases by Watson's theorem and also using the exact correlated two-nucleon wave functions. The effect of correlations and form factors is found to be crucially important at intermediate energies

    Background: Early menopause, defined as the cessation of ovarian function before the age of 45 y, affects ∼10% of women and is associated with higher risk of cardiovascular disease, osteoporosis, and other conditions. Few modifiable risk factors for early menopause have been identified, but emerging data suggest that high vitamin D intake may reduce risk. Objective: We evaluated how intakes of vitamin D and calcium are associated with the incidence of early menopause in the prospective Nurses' Health Study II (NHS2). Design: Intakes of vitamin D and calcium from foods and supplements were measured every 4 y with the use of a food-frequency questionnaire. Cases of incident early menopause were identified from all participants who were premenopausal at baseline in 1991; over 1.13 million person-years, 2041 women reported having natural menopause before the age of 45 y. We used Cox proportional hazards regression to evaluate relations between intakes of vitamin D and calcium and incident early menopause while accounting for potential confounding factors. Results: After adjustment for age, smoking, and other factors, women with the highest intake of dietary vitamin D (quintile median: 528 IU/d) had a significant 17% lower risk of early menopause than women with the lowest intake [quintile median: 148 IU/d; HR: 0.83 (95% CI: 0.72, 0.95); P -trend = 0.03]. Dietary calcium intake in the highest quintile (median: 1246 mg/d) compared with the lowest (median: 556 mg/d) was associated with a borderline significantly lower risk of early menopause (HR: 0.87; 95% CI: 0.76, 1.00; P -trend = 0.03). Associations were stronger for vitamin D and calcium from dairy sources than from nondairy dietary sources, whereas high supplement use was not associated with lower risk. Conclusions: Findings suggest that high intakes of dietary vitamin D and calcium may be modestly associated with a lower risk of early menopause.

    Full text: In a recent experiment, a stringent upper limit was placed on the atomic electric dipole moment (EDM) of 199 Hg corresponding to the best limit on an atomic EDM to date. This limit can be interpreted in terms of a limit on a parity-and time-invariance violating (P,T-odd) nuclear electric moment, the Schiff moment. This moment can arise in the nucleus due to an intrinsic EDM of an unpaired nucleon or a P,T-odd interaction between nucleons. In previous calculations the electrostatic potential of the Schiff moment was expressed in a singular form which must be treated carefully to avoid divergences in the electronic matrix elements. We have shown that the electric field distribution inside the nucleus arising from the Schiff moment is constant and directed along the nuclear spin. This allows us to express the Schiff moment in a form more convenient for numerical relativistic atomic calculations. We have calculated the atomic EDM induced in Hg due to the Schiff moment (for which no direct calculation has previously been performed) and have placed new limits on the fundamental P,T-odd parameters. These limits strongly constrain competing theories of CP-violation

    An experiment is in progess at TRIUMF to measure the parity-violating longitudinal analyzing power A z in polarizedp-p scattering at 222 MeV. Previous measurements at 15 and 45 MeV have determined the parity-mixed partial wave scattering amplitude to high precision. In contrast, only the ( 3 P 2 - 1 D 2 ) amplitude contributes to A z at 222 MeV. These two amplitudes yield complementary information on the underlying parity violating reaction mechanism. In a weak meson exchange model, the ( 3 P 2 - 1 D 2 ) amplitude is entirely due to rho meson exchange, and the present experiment affords a unique opportunity to measure the weak ρ-N coupling strength h ρ . At TRIUMF, a 500 nA beam of longitudinally polarized protons (p z ∼0.8) from the optically pumped polarized ion source will be scattered from a 20 cm liquid hydrogen target. A unique feature of this experiment is that A z will be measured in two different geometries (scattering and transmission mode) simultaneously, which will provide a crucial consistency check on the results. Monte Carlo simulations have confirmed that d.c. ionization chambers used to collect the transmitted and scattered protons in the two simultaneous measurements will achieve comparable statistical accuracies in the ∼ 300 hour counting time proposed for the experiment. High precision monitoring devices are being constructed and tested at TRIUMF to monitor changes in beam properties, such as beam position and residual transverse polarization, that can contribute to systematic errors in the parity violation measurements. The present status of the detector developments and systematic error controls will be discussed

    Our purpose in conducting this qualitative study was to examine how a multiethnic sample of women living in Hilo, Hawai'i, describe menopause. Interviews were conducted with 185 pre-, peri-, and post-menopausal women aged 45 to 55. We found that pre-menopausal women felt anxious compared with peri- and post-menopausal women's more affirmative attitudes of increasing confidence and freedom in this new cycle of life. A dominant theme was the construction of a post-menstrual identity. Peri-and post-menopausal women's attitudes were not biomedically oriented. Local culture and the island lifestyle may provide a positive atmosphere for women going through menopause.

  1. Analysing the Effect on CMB in a Parity and Charge Parity Violating Varying Alpha Theory

    In this paper we study in detail the effect of our recently proposed model of parity and charge-parity (PCP) violating varying alpha on the Cosmic Microwave Background (CMB) photon passing through the intra galaxy-cluster medium (ICM). The ICM is well known to be composed of magnetized plasma. According to our model, the polarization and intensity of the CMB would be affected when traversing through the ICM due to non-trivial scalar photon interactions. We have calculated the evolution of such polarization and intensity collectively, known as the stokes parameters of the CMB photon during its journey through the ICM and tested our results against the Sunyaev-Zel'dovich (SZ) measurement on Coma galaxy cluster. Our model contains a PCP violating parameter, {beta}, and a scale of alpha variation {omega}. Using the derived constrained on the photon-to-scalar conversion probability, {bar P}{sub {gamma}{yields}{phi}}, for Coma cluster in ref.[34] we found a contour plot in the ({omega},{beta}) parameter plane. The {beta} = 0 line in this parameter space corresponds to well-studied Maxwell-dilaton type models which has lower bound on {omega} {approx}> 6.4 x 10{sup 9} GeV. In general, as the absolute value of {beta} increases, lower bound on {omega} also increases. Our model in general predicts the modification of the CMB polarization with a non-trivial dependence on the parity violating coupling parameter {beta}. However, it is unconstrained in this particular study. We show that this effect can in principle be detected in the future measurements on CMB polarization such that {beta} can also be constrained.

    We discuss the status and prospects of an experimental program of parity-violating asymmetry measurements in the scattering of longitudinally polarized electrons off unpolarized fixed targets. In particular, we focus on those measurements where judicious choices of target and kinematics allows the theoretical predictions to be made purely in terms of fundamental electroweak couplings. If such asymmetries are measured with sufficient precision, they are sensitive to new physics at the TeV scale. The physics implications of recent results, experiments under construction and plans for the future are discussed.

    Background Chinese herbal medicine (CHM) usage is expected to increase as women suffering from menopausal symptoms are seeking alternative therapy due to concerns from the adverse effects (AEs) associated with hormone therapy (HT). Scientific evidence for their effectiveness and safety is needed. Objectives To evaluate the effectiveness and safety of CHM in the treatment of menopausal symptoms. Search methods We searched the Gynaecology and Fertility Group’s Specialised Register of controlled trials, Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), MEDLINE, Embase, CINAHL, AMED, and PsycINFO (from inception to March 2015). Others included Current Control Trials, Citation Indexes, conference abstracts in the ISI Web of Knowledge, LILACS database, PubMed, OpenSIGLE database, and China National Knowledge Infrastructure database (CNKI, 1999 to 2015). Other resources included reference lists of articles as well as direct contact with authors. Selection criteria Randomised controlled trials (RCTs) comparing the effectiveness of CHM with placebo, HT, pharmaceutical drugs, acupuncture, or another CHM formula in women over 18 years of age, and suffering from menopausal symptoms. Data collection and analysis Two review authors independently assessed 864 studies for eligibility. Data extractions were performed by them with disagreements resolved through group discussion and clarification of data or direct contact with the study authors. Data analyses were performed in accordance with Cochrane Collaboration guidelines. Main results We included 22 RCTs (2902 women). Participants were from different ethnic backgrounds with the majority of Chinese origin. When CHM was compared with placebo (eight RCTs), there was little or no evidence of a difference between the groups for the following pooled outcomes: hot flushes per day (MD 0.00, 95% CI −0.88 to 0.89; 2 trials, 199 women; moderate quality evidence); hot flushes per day assessed by an overall hot

    Migraine is most prevalent in women during their reproductive years. An understanding of the effects of menstruation and menopause on migraine can enable neurologists to provide targeted and appropriate medical and hormonal strategies, enabling their patients to achieve better control of migraine and reduced disability. This article reviews the effects of hormonal events on migraine and summarizes the evidence-based options available for management. Estrogen "withdrawal" during the late luteal phase of the natural menstrual cycle and the hormone-free interval of combined hormonal contraceptives has long been implicated in the pathophysiology of menstrual migraine. However, more recent research suggests that other independent mechanisms may be relevant. Prostaglandin inhibitors used for management of dysmenorrhea are effective for associated menstrual migraine, suggesting a common pathophysiology. The interplay between serotonin and estrogen also deserves further research. Menstrual and perimenopausal migraine can be managed effectively using a variety of strategies, the choice of which depends on the efficacy of acute treatment, predictability and regularity of menstruation, use of contraception, and presence of menstrual disorders or perimenopausal vasomotor symptoms.

  6. Analysis tools for discovering strong parity violation at hadron colliders

    2011-01-01

    Several arguments suggest parity violation may be observable in high energy strong interactions. We introduce new analysis tools to describe the azimuthal dependence of multiparticle distributions, or 'azimuthal flow'. Analysis uses the representations of the orthogonal group O(2) and dihedral groups D N necessary to define parity completely in two dimensions. Classification finds that collective angles used in event-by-event statistics represent inequivalent tensor observables that cannot generally be represented by a single 'reaction plane'. Many new parity-violating observables exist that have never been measured, while many parity-conserving observables formerly lumped together are now distinguished. We use the concept of 'event-shape sorting' to suggest separating right- and left-handed events, and we discuss the effects of transverse and longitudinal spin. The analysis tools are statistically robust, and can be applied equally to low or high multiplicity events at the Tevatron, RHIC or RHIC Spin, and the LHC.

  8. Iron-Based Superconductors as Odd-Parity Superconductors

    2013-07-01

    Full Text Available Parity is a fundamental quantum number used to classify a state of matter. Materials rarely possess ground states with odd parity. We show that the superconducting state in iron-based superconductors is classified as an odd-parity s-wave spin-singlet pairing state in a single trilayer FeAs/Se, the building block of the materials. In a low-energy effective model constructed on the Fe square bipartite lattice, the superconducting order parameter in this state is a combination of an s-wave normal pairing between two sublattices and an s-wave η pairing within the sublattices. The state has a fingerprint with a real-space sign inversion between the top and bottom As/Se layers. The results suggest that iron-based superconductors are a new quantum state of matter, and the measurement of the odd parity can help to establish high-temperature superconducting mechanisms.

    Full Text Available Magic states are eigenstates of non-Pauli operators. One way of suppressing errors present in magic states is to perform parity measurements in their non-Pauli eigenbasis and postselect on even parity. Here we develop new protocols based on non-Pauli parity checking, where the measurements are implemented with the aid of pre-distilled multiqubit resource states. This leads to a two step process: pre-distillation of multiqubit resource states, followed by implementation of the parity check. These protocols can prepare single-qubit magic states that enable direct injection of single-qubit axial rotations without subsequent gate-synthesis and its associated overhead. We show our protocols are more efficient than all previous comparable protocols with quadratic error reduction, including the protocols of Bravyi and Haah.

    Demonstrating quantum advantage with less powerful but more realistic devices is of great importance in modern quantum information science. Recently, a significant quantum speedup was achieved in the problem of learning a hidden parity function with noise. However, if all data qubits at the query output are completely depolarized, the algorithm fails. In this work, we present a quantum parity learning algorithm that exhibits quantum advantage as long as one qubit is provided with nonzero polarization in each query. In this scenario, the quantum parity learning naturally becomes deterministic quantum computation with one qubit. Then the hidden parity function can be revealed by performing a set of operations that can be interpreted as measuring nonlocal observables on the auxiliary result qubit having nonzero polarization and each data qubit. We also discuss the source of the quantum advantage in our algorithm from the resource-theoretic point of view.

  12. Calcium and vitamin D in post menopausal women

    Full Text Available Calcium and Vitamin D are widely used therapies for Osteoporosis. Vitamin D is not a vitamin in true sense since it is produced in response to the action of sunlight on skin. Vitamin D has multiple roles in the body, not all of them well-understood. Vitamin D supplementation must be considered a form of hormone replacement therapy. Therefore it raises all the questions about efficacy, dose, and side effects. The Efficacy of use of Calcium and Vitamin D in all post menopausal women in terms of the prevention of fracture is uncertain. The Annual worldwide sales of these supplements have been several billion dollars. The variation of the results from various studies of Calcium and Vitamin D supplementation in elderly women suggest that benefit of calcium plus vitamin D on bone mineral density or the risk of fracture is small and may vary from group to group and baseline Vitamin D status. Women taking supplemental vitamin D and calcium have a statistically increased incidence of renal stones, according to evidence from the Women′s Health Initiative. Studies have shown association between calcium use and increased risk for cardiovascular disease. In a recent review of evidence from 6 randomized trials evaluating the use of vitamin D and calcium to prevent fractures in postmenopausal women who are not living in a nursing home or other institution, the United States Preventive Task Force (USPTF found no evidence of a benefit from supplementation with 400 IU or less of vitamin D3 and 1000 mg or less of calcium. Also in a report from institute of Medicine Committee, there was insufficient evidence, particularly from randomized trials, that vitamin D treatment affected the risk of non skeletal outcomes like risk of cancer, cardiovascular disease, diabetes, infections, autoimmune disease, and other extra skeletal outcomes.

    In 2010, the Senegalese women’s movement, supported by political elites and international norms, managed to push for the adoption of one of the world’s most radical gender quota laws to date. This was achieved without the support of the powerful religious leaders, the marabouts. However, the marabouts fought back in the 2014 local elections and thwarted the full implementation of parity. This CMI Insight explores the on-going fight for parity in Senegal.

The reason for the choice of this particular transition, a description of the method, the results to data, and a brief description of the future plans are given. The very preliminary results suggest that the Weinberg--Salam model correctly describes parity nonconservation effects in atoms. 5 references

    The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women. This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires. There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6 ± 3.2) and Tribulus (10.2 ± 3.2) groups in the domains of desire and sexual interest (p ≤ 0.001), foreplay (3.3 ± 1.5 versus 4.2 ± 1.0) (p ≤ 0.01), arousal and harmonious interaction with the partner (5.7 ± 2.1 versus 7.2 ± 2.6) (p ≤ 0.01), and comfort in sexual intercourse (6.5 ± 2.4 versus 8.0 ± 1.9) (p ≤ 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28).

  20. Constraints on a Parity-Conserving Interaction

    Science.gov (United States)

    van Oers, Willem T. H.

    Time-reversal-invariance non-conservation has for the first time been unequivocally demonstrated in a direct measurement at CPLEAR. One then can ask the question: What about tests of time-reversal-invariance in systems other than the kaon system? Tests of time-reversal-invariance can be distinguished as belonging to two classes: the first one deals with parity violating (P-odd)/time-reversal-invariance-odd (T-odd) interactions, while the second one deals with P-even/T-odd interactions (assuming CPT conservation this implies C-conjugation non-conservation). Limits on a P-odd/T-odd interaction follow from measurements of the electric dipole moment of the neutron (with a present upper limit of 6 × 10-26 e.cm [95% C.L.]). It provides a limit on a P-odd/T-odd pion-nucleon coupling constant which is less than 10-4 times the weak interaction strength. Experimental limits on a P-even/T-odd interaction are much less stringent. Following the standard approach of describing the nucleon-nucleon interaction in terms of meson exchanges it can be shown that only charged rho-meson exchange and A1-meson exchange can lead to a P-even/T-odd interaction. The better constraints stem from measurements of the electric dipole moment of the neutron and from measurements of charge-symmetry breaking in neutron-proton elastic scattering. The latter experiments were executed at TRIUMF (497 and 347 MeV) and at IUCF (183 MeV). Weak decay experiments may provide limits which will possibly be comparable. All other experiments, like gamma decay experiments, detailed balance experiments, polarization-analyzing power difference determinations, and five-fold correlation experiments with polarized incident nucleons and aligned nuclear targets, have been shown to be at least an order of magnitude less sensitive. The question then emerges: is there room for further experimentation?
