assessment of frequency of obesity and comorbidities in women with postmenopausal osteoporosis (OP). cross-sectional study included 243 postmenopausal symptomatic women with OP diagnosed by dual energy lumbar spine absorptiometry. normal body mass was found in 74 women (30.5%), 105 persons (43.2%) had overweight and 64 patients (26.3%) were obese. Obese OP patients had significantly higherfrequency of arterial hypertension, chronic heart failure, osteoarthritis and glucose metabolism disorders than those with normal body mass. Obese persons also had more severe menopausal symptoms than women with normal body mass. There was no difference in non-traumatic fractures between obese, overweight and slim patients. Thus, postmenopausal OP in obese women was associated with numerous comorbidities and more severe menopausal symptoms.

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{sub total} and a perfusion-insensitive ADC{sub 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{sub total} and ADC{sub high} showed good reproducibility (r% = 17.6, 22.4). ADC{sub 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{sub total} 1.46 {+-} 0.3 x 10{sup -3} mm{sup 2}/s, ADC{sub high} 1.33 {+-} 0.3 x 10{sup -3} mm{sup 2}/s) compared with the premenopausal breast (ADC{sub total} 1.84 {+-} 0.26 x 10{sup -3} mm{sup 2}/s, ADC{sub high} 1.77 {+-} 0.26 x 10{sup -3} mm{sup 2}/s; both P < 0.001). No significant difference was seen in ADC values in relation to menstrual cycle (ADC{sub total} P = 0.2, ADC{sub high} P = 0.24) or between postmenopausal women taking or not taking oestrogen supplements (ADC{sub total} P = 0.6, ADC{sub 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.)

This study aims to compare eating behaviors, body satisfaction, exercise, and life satisfaction between normal-weight and overweight postmenopausal women and to examine the predictors of disordered eating and life satisfaction among postmenopausal women (n = 294). The overweight group had more eating disordered behavior, more body dissatisfaction, and lower physical quality of life. The increase of age predicted less disordered eating. Higher BMI, the perception of an ideal weight lower than the current one, lower body satisfaction, and physical quality of life predicted disordered eating. Higher body satisfaction, less psychosocial discomfort, and a greater degree of sexual symptom discomfort predicted life satisfaction.

Osteoporosis is a common disease, characterized by low bone mass with micro-architectural disruption and skeletal fragility, resulting in an increased risk of fracture. A substantial number of studies has examined the possible relationship between body weight, bone mineral density and fracture risk in post-menopausal women, with the majority of them concluding that low body weight correlates with increased risk of fracture, especially hip fracture. Controversies about the potential protective effect of obesity on osteoporosis and consequent fracture risk still exist. Several recent studies question the concept that obesity exerts a protective effect against fractures, suggesting that it stands as a risk factor for fractures at specific skeletal sites, such as upper arm. The association between body weight and fracture risk is complex, differs across skeletal sites and body mass index, and is modified by the interaction between body weight and bone mineral density. Some potential explanations that link obesity with increased fracture risk may be the pattern of falls and impaired mobility in obese individuals, comorbidities, such as asthma, diabetes and early menopause, as well as, increased parathyroid hormone and reduced 25-hydroxy-vitamin D concentrations. © 2015 World Obesity.

Full Text Available Abstract Background Accumulation of excess body fat increases breast cancer risk after menopause. Whether the localized breast is differently influenced by adipose tissue compared to the rest of the body, has not been well studied. Our purpose was to demonstrate feasibility and preliminarily evaluate serum-based and localized breast biomarker changes resulting from a weight loss intervention among obese postmenopausal women. Methods We conducted a 12-week pilot controlled dietary and exercise intervention among healthy obese postmenopausal women, collected serum and breast ductal fluid before and after the intervention, and estimated the association with systemic and localized biomarker changes. We recruited 7 obese (mean body mass index = 33.6 kg/m2 postmenopausal women. We collected samples at baseline and the 12th week for: anthropometry; phlebotomy; dual-energy x-ray absorptiometry (lean and fat mass; exercise fitness (maximum oxygen consumption (VO2Max; 1-repetition strength maximum; and breast ductal lavage. Results Changes from baseline occurred in body composition and exercise performance including fat mass loss (14% average drop, VO2Max (+36% increase and strength improvement (+26%. Breast ductal fluid markers declined from baseline with estradiol showing a 24% reduction and IL-6 a 20% reduction. We also observed serum biomarker reductions from baseline including leptin (36% decline, estrone sulfate (−10%, estradiol (−25%, and Il-6 (−33%. Conclusions Conduct of the diet and exercise intervention, collection of ductal fluid, and measurement of hormones and cytokines contained in the ductal fluid were all feasible. We preliminarily demonstrated estradiol and IL-6 reductions from baseline in both serum and breast ductal fluid among obese postmenopausal women who participated in the 12-week weight loss diet and exercise intervention.

Full Text Available Objective. The aim of this study is to investigate if weight fluctuation is an independent risk factor for postmenopausal breast cancer (PBC among women who gained weight in adult years. Methods. NHANES I Epidemiologic Follow-Up Study (NHEFS database was used in the study. Women that were cancers-free at enrollment and diagnosed for the first time with breast cancer at age 50 or greater were considered cases. Controls were chosen from the subset of cancers-free women and matched to cases by years of follow-up and status of body mass index (BMI at 25 years of age. Weight fluctuation was measured by the root-mean-square-error (RMSE from a simple linear regression model for each woman with their body mass index (BMI regressed on age (started at 25 years while women with the positive slope from this regression were defined as weight gainers. Data were analyzed using conditional logistic regression models. Results. A total of 158 women were included into the study. The conditional logistic regression adjusted for weight gain demonstrated positive association between weight fluctuation in adult years and postmenopausal breast cancers (odds ratio/OR = 1.67; 95% confidence interval/CI: 1.06–2.66. Conclusions. The data suggested that long-term weight fluctuation was significant risk factor for PBC among women who gained weight in adult years. This finding underscores the importance of maintaining lost weight and avoiding weight fluctuation.

Estrogen exposure is important in the pathogenesis of breast cancer and is a contributing risk factor. In this study we quantified estrogen receptor (ER) alpha expression in normal breast epithelium (NBR) in women with breast cancer and correlated it with breast cancer subtypes. Tissue microarrays were constructed from 204 breast cancer patients for whom normal breast tissue away from tumor was available. Slides stained with ER were scanned and expression in normal terminal duct lobular epithelium was quantitated using computer-assisted image analysis. ER expression in normal terminal duct lobular epithelium of postmenopausal women with breast cancer was significantly associated with estrogen and triple (estrogen, progesterone receptors, and HER2) negative phenotypes. Also increased age at diagnosis was significantly associated with ER expression in NBR. ER positivity in normal epithelium did not vary by tumor size, lymph node status, tumor grade, or stage. On the basis of quantitative image analysis, we confirm that ER expression in NBR increases with age in women with breast cancer, and report for the first time, a significant association between ER expression in NBR with ER-negative and triple-negative cancers in postmenopausal women.

High-protein (HP) intake during weight loss (WL) therapy is often recommended because it reduces the loss of lean tissue mass. However, HP intake could have adverse effects on metabolic function, because protein ingestion reduces postprandial insulin sensitivity. In this study, we compared the effects of ∼10% WL with a hypocaloric diet containing 0.8 g protein/kg/day and a hypocaloric diet containing 1.2 g protein/kg/day on muscle insulin action in postmenopausal women with obesity. We found ...

The inter-relationships between smoking habits and weight gain are complex. However, few studies have examined the association of smoking habits with weight gain over the life course. Major smoking parameters and weight gain over time were examined in a large cohort of postmenopausal women aged 50-79 years at enrollment between 1993 and 1998 (N=161,808) and followed through 2014 (analyses conducted in 2016). Cross-sectional analyses were used to assess the association of smoking and body weight at baseline. Retrospective data were used to correlate smoking status with body weight over a 45-year period prior to enrollment. In addition, the association of smoking with weight gain over 6 years of follow-up was examined. At baseline, women who had quit smoking prior to enrollment weighed 4.7 kg more than current smokers and 2.6 kg more than never smokers. Former, never, and current smokers all gained weight over the 45-year period from age 18 years to time of enrollment (average age, 63 years): 16.8, 16.4, and 14.6 kg, respectively. In prospective analyses, women who were current smokers at baseline but who quit smoking during follow-up gained more than 5 kg by Year 6 compared with current smokers at baseline who continued to smoke. Among long-term quitters, greater intensity of smoking and more recent quitting were associated with greater weight gain. These results suggest that excess weight gain associated with smoking cessation occurs soon after quitting and is modest relative to weight gain in never smokers over the adult lifespan.

Erkan Mesci

2016-08-01

Full Text Available Objective: The aim of this study was to investigate the association among obesity with bone mineral density (BMD and subsequent fracture risk among postmenopausal women with a previous forearm fracture. Materials and Methods: The study enrolled obese (n=40 and normal-weight (n=40 postmenopausal women who had a previous forearm fracture. BMD measurements were obtained using a GE-LUNAR DPX dual energy X-ray absorptiometry scan for all subjects. FRAX® fracture risk scores were calculated taking into account former fractures and current risk factors of the subjects. Both groups were compared with respect to their BMD values, T scores, FRAX® risk scores and frequency of previous fractures. Results: No difference was observed between groups with regard to mean age, mean age of menopause onset and mean serum calcium, phosphorus and alkaline phosphatase levels (p>0.05 for all. Statistically, obese patients showed highly significantly greater mean BMD values at lumbar spine (L1-L4 and femoral neck in comparison to subjects with normal body weight (p=0.000 for all. Obese patients had a lower 10-year probability of a major osteoporotic fracture on average as determined by FRAX® fracture risk score compared to that in normal-weight subjects (p<0.05. Also, obese group had a lower 10-year probability of a hip fracture versus normal-weight subjects (p<0.01. Both groups were found to have a similar frequency of previous fractures. Conclusion: Although obese patients in this study had greater BMD values and lower FRAX® risk scores, the probability of subsequent fractures predicted for the obese group was not lower when compared to that predicted for normal-weight group. It should be kept in mind that obesity may not necessarily be protective against fractures and treatment algorithms based solely on BMD might be inadequate to predict future fracture risk.

Masheb, Robin; White, Marney A

The aim of the present study was to examine overweight bulimia nervosa (BN) in a community sample of women. Volunteers (n = 1964) completed self-report questionnaires of weight, binge eating, purging, and cognitive features. Participants were classified as overweight (body mass index ≥25) or normal weight (body mass index <25). Rates of BN within the overweight and normal-weight classes did not differ (6.4% vs 7.9%). Of the 131 participants identified as BN, 64% (n = 84) were classified as overweight BN and 36% (n = 47) as normal-weight BN. The overweight BN group had a greater proportion of ethnic minorities and reported significantly less restraint than the normal-weight BN group. Otherwise, the 2 groups reported similarly, even in terms of purging and depression. In summary, rates of BN did not differ between overweight and normal-weight women. Among BN participants, the majority (two thirds) were overweight. Differences in ethnicity and restraint, but little else, were found between overweight and normal-weight BN. Findings from the present study should serve to increase awareness of the weight range and ethnic diversity of BN, and highlight the need to address weight and cultural sensitivity in the identification and treatment of eating disorders.

CD38 is associated with premenopausal and postmenopausal bone mineral density and postmenopausal bone loss.

LENUS (Irish Health Repository)

Drummond, Frances J

2012-02-03

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

Changes in weight, waist circumference and compensatory responses with different doses of exercise among sedentary, overweight postmenopausal women.

Full Text Available It has been suggested that exercise training results in compensatory mechanisms that attenuate weight loss. However, this has only been examined with large doses of exercise. The goal of this analysis was to examine actual weight loss compared to predicted weight loss (compensation across different doses of exercise in a controlled trial of sedentary, overweight or obese postmenopausal women (n = 411.Participants were randomized to a non-exercise control (n = 94 or 1 of 3 exercise groups; exercise energy expenditure of 4 (n = 139, 8 (n = 85, or 12 (n = 93 kcal/kg/week (KKW. Training intensity was set at the heart rate associated with 50% of each woman's peak VO(2 and the intervention period was 6 months. All exercise was supervised. The main outcomes were actual weight loss, predicted weight loss (exercise energy expenditure/ 7700 kcal per kg, compensation (actual minus predicted weight loss and waist circumference. The study sample had a mean (SD age 57.2 (6.3 years, BMI of 31.7 (3.8 kg/m(2, and was 63.5% Caucasian. The adherence to the intervention was >99% in all exercise groups. The mean (95% CI weight loss in the 4, 8 and 12 KKW groups was -1.4 (-2.0, -0.8, -2.1 (-2.9, -1.4 and -1.5 (-2.2, -0.8 kg, respectively. In the 4 and 8 KKW groups the actual weight loss closely matched the predicted weight loss of -1.0 and -2.0 kg, respectively, resulting in no significant compensation. In the 12 KKW group the actual weight loss was less than the predicted weight loss (-2.7 kg resulting in 1.2 (0.5, 1.9 kg of compensation (P<0.05 compared to 4 and 8 KKW groups. All exercise groups had a significant reduction in waist circumference which was independent of changes in weight.In this study of previously sedentary, overweight or obese, postmenopausal women we observed no difference in the actual and predicted weight loss with 4 and 8 KKW of exercise (72 and 136 minutes respectively, while the 12 KKW (194 minutes produced only about half of the predicted

In covariate (sub)models of population pharmacokinetic models, most covariates are normalized to the median value; however, for body weight, normalization to 70 kg or 1 kg is often applied. In this article, we illustrate the impact of normalization weight on the precision of population clearance (CL pop ) parameter estimates. The influence of normalization weight (70, 1 kg or median weight) on the precision of the CL pop estimate, expressed as relative standard error (RSE), was illustrated using data from a pharmacokinetic study in neonates with a median weight of 2.7 kg. In addition, a simulation study was performed to show the impact of normalization to 70 kg in pharmacokinetic studies with paediatric or obese patients. The RSE of the CL pop parameter estimate in the neonatal dataset was lowest with normalization to median weight (8.1%), compared with normalization to 1 kg (10.5%) or 70 kg (48.8%). Typical clearance (CL) predictions were independent of the normalization weight used. Simulations showed that the increase in RSE of the CL pop estimate with 70 kg normalization was highest in studies with a narrow weight range and a geometric mean weight away from 70 kg. When, instead of normalizing with median weight, a weight outside the observed range is used, the RSE of the CL pop estimate will be inflated, and should therefore not be used for model selection. Instead, established mathematical principles can be used to calculate the RSE of the typical CL (CL TV ) at a relevant weight to evaluate the precision of CL predictions.

The level of awareness about osteoporosis in postmenopausal women who are the common sufferers. This study aims to evaluate the level of awareness in postmenopausal women using the Osteoporosis Health Belief Scale (OHBS). Osteoporosis has emerged as a common health problem in geriatric population. A proactive role needs to be played for preventing its consequences. Before initiating any preventive measures, an evaluation of awareness level of the target population is necessary. The questionnaire-based study design was used for this study. A questionnaire (OHBS)-based study in 100 postmenopausal women in Chandigarh was conducted. The bone mineral density (BMD) was measured in each case by dual energy X-ray absorptiometry. Height, weight, and body mass index (BMI) of the participants were noted. Statistical analysis was conducted to evaluate any correlation between the various components of the OHBS and the BMD. No statistically significant difference was noted in the seven component parameters of OHBS among the normal, osteopenic, and osteoporotic women suggesting that the health belief regarding susceptibility is not much different between the three groups of the study population. A statistically significant difference between the mean BMI of normal and osteoporotic population was noted. The results show that there is a great deficit in the awareness level of postmenopausal Indian women regarding osteoporosis. Most of the women were unaware of the condition and the means to prevent it. The study emphasizes that health care professionals have lot of ground to cover to decrease the incidence of osteoporosis and its associated health problem.

Obese and sedentary persons have increased risk for cancer; inflammation is a hypothesized mechanism. We examined the effects of a caloric restriction weight loss diet and exercise on inflammatory biomarkers in 439 women. Overweight and obese postmenopausal women were randomized to 1-year: caloric restriction diet (goal of 10% weight loss, N = 118), aerobic exercise (225 min/wk of moderate-to-vigorous activity, N = 117), combined diet + exercise (N = 117), or control (N = 87). Baseline and 1-year high-sensitivity C-reactive protein (hs-CRP), serum amyloid A (SAA), interleukin-6 (IL-6), leukocyte, and neutrophil levels were measured by investigators blind to group. Inflammatory biomarker changes were compared using generalized estimating equations. Models were adjusted for baseline body mass index (BMI), race/ethnicity, and age. Four hundred and thirty-eight (N = 1 in diet + exercise group was excluded) were analyzed. Relative to controls, hs-CRP decreased by geometric mean (95% confidence interval, P value): 0.92 mg/L (0.53-1.31, P restriction weight loss diet with or without exercise reduces biomarkers of inflammation in postmenopausal women, with potential clinical significance for cancer risk reduction. ©2012 AACR

Full Text Available Weight perceptions and weight control behaviors have been documented with underweight and overweight adolescents, yet limited information is available on normal weight adolescents. This study investigates the prevalence of overweight misperceptions and weight control behaviors among normal weight adolescents in the U.S. by sociodemographic and geographic characteristics. We examined data from the 2003 Youth Risk Behavior Survey (YRBS. A total of 9,714 normal weight U.S. high school students were included in this study. Outcome measures included self-reported height and weight measurements, overweight misperceptions, and weight control behaviors. Weighted prevalence estimates and odds ratios were computed. There were 16.2% of normal weight students who perceived themselves as overweight. Females (25.3% were more likely to perceive themselves as overweight than males (6.7% (p < 0.05. Misperceptions of overweight were highest among white (18.3% and Hispanic students (15.2% and lowest among black students (5.8%. Females (16.8% outnumbered males (6.8% in practicing at least one unhealthy weight control behavior (use of diet pills, laxatives, and fasting in the past 30 days. The percentage of students who practiced at least one weight control behavior was similar by ethnicity. There were no significant differences in overweight misperception and weight control behaviors by grade level, geographic region, or metropolitan status. A significant portion of normal weight adolescents misperceive themselves as overweight and are engaging in unhealthy weight control behaviors. These data suggest that obesity prevention programs should address weight misperceptions and the harmful effects of unhealthy weight control methods even among normal weight adolescents.

Periodontitis and overweight/obesity prevalence are both increasing worldwide. Overweight/obesity has been suggested as a risk factor for developing periodontitis. The aim of this study was to determine the association between obesity and periodontitis among postmenopausal Jordanian women. Cross-sectional associations between obesity and periodontitis were examined in 400 postmenopausal women aged 50-79 years. All women completed a questionnaire, had a clinical periodontal examination and had their weight and height recorded. Multivariable analysis was carried out using logistic regression with adjustment for possible confounders. Based on body mass index (BMI), 23.5% of the women were considered overweight and 70% were obese. Obese participants with BMI≥25 had decreased odds (OR) for having periodontitis compared to participants with normal weight (OR: 0.54; 95% confidence interval [CI]: 0.27-0.87). The obese patients showed significantly higher loss of clinical attachment (CAL), calculus, as well as plaque and gingival index and as compared to normal and overweight (pobese women as measured by average percent of sites with the deepest CAL≥5 mm (p=0.025). There was no significant difference in mean and percentage of sites with alveolar crestal bone loss (ACH) among different categories of obesity. In conclusion, BMI may be inversely associated with prevalence of periodontitis but positively related to the severity of periodontitis assessed by several periodontal parameters such as CAL, recession, plaque, and calculus. Additional prospective studies to further quantify, or understand the mechanisms, of this association are merited. Copyright © 2015 Asia Oceania Association for the Study of Obesity.

To compare physical activity patterns between morbidly obese and normal-weight women. Daily physical activity of 18 morbidly obese and 7 normal-weight women aged 30-58 years was measured for 2 days using the Intelligent Device for Energy Expenditure and Activity (IDEEA) device. The obese group spent about 2 hr/day less standing and 30 min/day less walking than did the normal-weight group. Time spent standing (standing time) was positively associated with time spent walking (walking time). Age- and walking time-adjusted standing time did not differ according to weight status. Promoting standing may be a strategy to increase walking.

To investigate the differences in the dietary patterns of Polish overweight and normal weight adolescents. The study was carried out on a group of 1906 pupils from gymnasium (lower secondary school) aged 13-15 years, of whom 953 were overweight and 953 had normal body mass. The sample was taken from a representative group of 8386 pupils. Their height and body weight were measured, and their BMI was calculated. Overweight was defined as BMI ł85 percentile for gender and age. Using the method of "selection in pairs", each overweight pupil was paired with a pupil with normal body weight. The research tool was a self-reported questionnaire, containing questions regarding how often selected food products were usually consumed during the week, how regularly basic meals (breakfast, lunch, supper) were eaten, and data on snacking. Overweight adolescents consumed unhealthy products such as sweets and crisps significantly less often than their peers with appropriate body mass. Overweight girls ate dark bread significantly more often, and consumed soft drinks less often than their peers with normal weight. Overweight adolescents had more irregular meals than those with normal weight: only 44% overweight adolescents had breakfast every day, significantly less than adolescents with normal weight. Nevertheless, overweight teenagers snacked significantly less often than young people with normal body mass. The overweight teenagers also less often chose snacks with high fat content, sugar and salt, and more often vegetables, fruits, as well as yoghurt and kefir. 1. Our study shows that compliance of low energy diet alone does not ensure the maintenance of normal body weight. Irregularity of meals and breakfast skipping play an important role in developing overweight and obesity in adolescents. 2. In future studies on dietary patterns in a larger sample of adolescents, emphasis should be placed on adding questions about portion size, food preparation and meal time. Eating

Full Text Available Abstract Background Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. Methods All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. Results In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004. Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR = 3.21, 95% confidence interval (CI: 1.15–8.47]. Conclusion The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

The human pinworm Enterobius vermicularis is normally found within the human gastrointestinal tract. Pregnant females migrate out of their host's anus at night to lay their eggs perianally. As a consequence of this nocturnal migration some worms find their way into adjacent orifices, most commonly the female genitourinary tract, producing irritative symptoms such as vulvovaginitis. A case of pinworm infestation of the uterus presented as postmenopausal bleeding.

Hypertension becomes more prevalent in women during their postmenopausal years. Nighttime systolic blood pressure (SBP) is especially predictive of adverse cardiac events, and the relationship between rising nighttime SBP and cardiovascular risk increases more rapidly in women compared with men. The reasons for the prognostic significance of nighttime SBP are not completely known but may involve vascular endothelial dysfunction. The purposes of this study were to examine the relationship between nighttime SBP and endothelial function, as assessed by brachial artery flow-mediated dilation (FMD), and to determine whether postmenopausal women with nighttime hypertension (SBP ≥120 mm Hg) evidenced greater endothelial dysfunction compared with women with normal nighttime SBP. One hundred postmenopausal women (mean [SD] age, 65.8 [7.5] y; mean [SD] body mass index, 28.3 [4.7] kg/m; hypertension, 47%; coronary artery disease, 51%; mean [SD] clinic SBP, 137 [17] mm Hg; mean [SD] clinic diastolic blood pressure, 67 [11] mm Hg; nighttime hypertension, 34 women) underwent 24-hour ambulatory blood pressure monitoring, actigraphy, and brachial artery FMD assessment. Multivariate regression models showed that higher nighttime SBP and larger baseline artery diameter were inversely related to FMD. Nighttime SBP and baseline artery diameter accounted for 23% of the variance in FMD. After adjustment for baseline artery diameter, women with nighttime hypertension had lower mean (SD) FMD than women with normal nighttime SBP (2.95% [0.65%] vs 5.52% [0.46%], P = 0.002). Nighttime hypertension is associated with reduced endothelial function in postmenopausal women. Research examining the therapeutic benefits of nighttime hypertension treatment on endothelial function and future cardiovascular risk in postmenopausal women is warranted.

Full Text Available Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4    BACKGROUND: In postmenopausal women, the risk of having cardiac diseases, especially high blood pressure, is increased due to the decrease in secretion of estrogen. The goal of this study was to evaluate the effect of 8 weeks of aquatic resistance training on blood pressure and physical function of postmenopausal women.    METHODS: In this quasi-experimental study, 24 postmenopausal women (age: 53-60 years, BMI= 29.23 ± 5.27kg/m2  ( were randomly divided into experimental (n = 14 and control (n = 10 groups. Women in the experimental group participated in an aquatic exercise program for 8 weeks (3 sessions per week in the deep parts of the pool. Training included walking and running in water with water dumbbells weighing 250 grams. Before and after the exercise period, the body composition, blood pressure, dynamic balance, and flexibility of the subjects were measured.    RESULTS: According to the T-score, the average systolic blood pressure in the experimental group significantly decreased (9.29% (P = 0.001. Dynamic balance and flexibility, respectively, significantly increased by 22.02% and 24.4% (P < 0.01. No significant changes were observed in body fat and weight.    CONCLUSION: Due to the positive effect of aquatic resistance training on blood pressure, dynamic balance, and flexibility these exercises are recommended for postmenopausal women.   Keywords: Menopausal Women, Blood Pressure, Flexibility, Aquatic Resistance Training

Full Text Available In the present study, the contribution of various biological and lifestyle factors toward progression to hypertension are examined among menopausal and postmenopausal women. A cross-sectional study among 245 women of 20 to 65 years was conducted. Besides blood pressure, fat percentage using bio-electric impedance analyzer and adiposity indices such as body mass index (BMI, waist–hip ratio (WHR, and waist–height ratio (WHtR were taken. Mean, standard deviation, ANOVA, and multinomial logistic were used to analyze the data. Statistically significant differences (p< .001 for blood pressure among postmenopausal and premenopausal women were found. Among both premenopausal and postmenopausal women, the prehypertensive and hypertensive group showed significant differences with the normotensive women for body weight (p< .005, regional obesity, and general obesity. Low educational level, working status of women, socioeconomic status, nuclear family setup, postmenopausal status, and obesity were found to be the likely risk factors for prehypertension or hypertension among women.

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

Low body mass index (BMI) is a recognized risk factor for fragility fracture, whereas obesity is widely believed to be protective. As part of a clinical audit of guidance from the National Institute of Health and Clinical Excellence (NICE), we have documented the prevalence of obesity and morbid obesity in postmenopausal women younger than 75 years of age presenting to our Fracture Liaison Service (FLS). Between January 2006 and December 2007, 1005 postmenopausal women aged less than 75 years with a low-trauma fracture were seen in the FLS. Of these women, 805 (80%) underwent assessment of bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA), and values for BMI were available in 799. The prevalence of obesity (BMI 30 to 34.9 kg/m(2)) and morbid obesity (BMI > or = 35 kg/m(2)) in this cohort was 19.3% and 8.4%, respectively. Normal BMD was reported in 59.1% of obese and 73.1% of morbidly obese women, and only 11.7% and 4.5%, respectively, had osteoporosis (p obesity in postmenopausal women presenting to the FLS with low-trauma fracture. Most of these women had normal BMD, as measured by DXA. Our findings have important public heath implications in view of the rapidly rising increase in obesity in many populations and emphasize the need for further studies to establish the pathogenesis of fractures in obese individuals and to determine appropriate preventive strategies.

Full Text Available Previous researchers have described the relation between physical self-concept and body mass in adolescents, but those relationships have not been clearly specified by gender. The purpose of this study is to explore physical self-concepts of normal-weight and over-weight Serbian adolescents with respect to gender. The sample consisted of 417 primary school students (229 boys and 188 girls with the average age 13.6 (SD=0.73 years who were divided into normal-weight and overweight groups according to body mass index. To assess the multidimensional physical self-concept, Physical Self-Description Questionnaire (PSDQ was administered. Results showed that overweight adolescents had significantly lower scores than normal-weight on all PSDQ scales except Health and Strength. Differences were greater among girls than boys. Discriminant analysis showed that the scales Body Fat, Endurance and Sports Competence best differentiated normal-weight boys from other students. Also, discriminant analysis showed that, besides the scale Body Fat, scales Flexibility, Self-Esteem, and Coordination best differentiated normal-weight girls from other students. Results indicate that for better understanding of the relationship between adolescent’s physical self-concept and body mass one must take gender into account. Results are potentially valuable for preventing overweight through physical education.

Due to its incidence and clinical consequences osteoporosis followed by vertebral, hip, and forearm fractures represents an outstanding problem of nowadays' health care. Because of its high mortality rate hip fractures are of special interest. The number of fractures caused by postmenopausal osteoporosis increases with age. Costs of examinations and treatment of women with postmenopausal osteoporosis and fractures are also increasing and represent a significant amount all over the world. Organization of Osteoporosis Centres in Hungary was founded in 1995 and has been since functioning, however, only the one-sixth of osteoporotic patients are treated. Several risk factors are known in the pathogenesis of osteoporosis, first of all the lack of sufficient calcium and vitamin D intake, age, genetic factors, and circumstances known to predispose falling. Estrogen deficiency is the most likely cause of postmenopausal osteoporosis. Osteodensitometry by DEXA is the most important method to evaluate osteoporosis, since decrease in bone mineral density strongly correlates with fracture incidence. Physical, radiologic, and laboratory examination are also required at the first visit and during follow-up. The quantity of bone can hardly be influenced after the 35th year of age, thus prevention of osteoporosis has special significance: appropriate calcium and vitamin D supplementation, weight-bearing sports and physical activity can prevent fractures. According to the results from studies fulfilling the criteria of evidence-based medicine, first choice treatment of osteoporosis involves hormone replacement therapy, bisphosphonates, the tissue specific tibolone, raloxifen and calcitonin. Calcium and vitamin D supplementation are always necessary to be added to any antiporotic treatment. Other combinations of different antiporotic drugs are useless and make the treatment more expensive. Other treatments like massage, physiotherapy, hip-protecting pants, etc. as well as

Genital tuberculosis in postmenopausal women with variable clinical presentations: A report of 3 cases

Directory of Open Access Journals (Sweden)

Ashima Arora

2018-04-01

Full Text Available Genital tuberculosis is usually diagnosed in young women being assessed for infertility. After menopause it usually presents with symptoms resembling endometrial malignancy, such as postmenopausal bleeding, persistent vaginal discharge and pyometra. The diagnosis is made by detection of acid-fast bacilli on microscopy or bacteriological culture and/or presence of epithelioid granuloma on biopsy. Anti-tubercular therapy involves the use of rifampicin, isoniazid, pyrazinamide and ethambutol. Surgery is indicated if a pelvic mass and recurrence of pain or bleeding persist after 9 months of treatment. Three cases of genital tuberculosis in postmenopausal women with different clinical presentations are reported. The first woman presented with ascites and weight loss. The second had postmenopausal bleeding with a pipelle biopsy suggestive of endometrial intraepithelial neoplasia. The third presented with weight loss and a palpable abdominal mass. Pelvic malignancy was initially suspected but a diagnosis of tuberculosis was made following pre-operative endometrial biopsy, bacteriological culture and intra-operative frozen section. All three women responded to anti-tubercular therapy. Keywords: Genital tuberculosis, Postmenopausal, Endometrial intraepithelial neoplasia, Anti-tubercular therapy, Endometrial biopsy

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

Sensory properties of some foods may be of importance to energy consumption and thus the development and maintenance of childhood obesity. This study compares selected food related qualities in overweight and normal weight children. Ninety-two participants were included; 55 were overweight with a mean age of 11.6 years (range 6-18 years) and a mean BMI z-score of 2.71 (range 1.29-4.60). The 37 normal weight children had a mean age of 13.0 years (range 6-19 years) and a mean BMI z-score of 0.16 (range -1.71 to 1.24). All children completed a half-hour long meal test consisting of alternation between consumption of foods and answering of questionnaires. Compared to the normal weight, the overweight children displayed lower self-reported intake paces (χ 2 (2) = 6.3, p = 0.04), higher changes in liking for mozzarella (F(1,63) = 9.55, p = 0.003) and pretzels (F(1,87) = 5.27, p = 0.024), and declines in wanting for something fat, of which the normal weight children displayed an increase (F(1,83) = 4,10, p = 0.046). No differences were found for sensory-specific satiety, wanting for the main food yoghurt, hunger, or satiety. In conclusion, overweight children did not differ from normal weight children in terms of sensory-specific satiety, hunger, or satiety. However, overweight children had lower intake paces and appeared to differ from normal weight children regarding foods with a fatty taste. Copyright © 2016 Elsevier Ltd. All rights reserved.

Assessment of bone mineral density and other risk factors of osteoporosis in postmenopausal age group of Pakistani population and to compare them with premenopausal group. The risk factors of osteoporosis were studied both in premenopausal and postmenopausal groups. These risk factors can be exogenous or endogenous. Endogenous risk factors are aging, altered menstrual status, low bone mass, positive family history and oestrogen deficiency. Exogenous factors include lack of adequate nutrition (milk, calcium, vitamin D etc.) and lack of physical exercise. These risk factors were evaluated by taking history, recording height and weight, doing blood parameters and checking bone mineral density. Oestrogen level was carried out by the Eliza technique. Bone mass density was carried out by the bone heel densitometer. The data was analyzed statistically and the values of two groups were compared. The risk factors in postmenopausal group were low BMD, low oestrogen levels, poor intake of milk and calcium and lack of physical exercise. All women should get checked their BMD in this age group. Regular exercise and adequate calcium intake can still help in postmenopausal age group. (author)

Osteoporosis is a major problem in contemporary society. However, there is not enough data on multiparity and osteoporosis from developing and/or undeveloped countries on a large scale. Selection of participants in this study was aimed at the detection of bone status in healthy (normal bone mineral density) postmenopausal (n = 46, 55.3 +/- 6.7 years) and osteoporotic postmenopausal women (n: 33) of similar age. Bone mineral density (BMD) was evaluated using dual energy X-ray absorptiometry. At the DEXA evaluation, 33 women had osteoporotic (T score below -2.5) and 46 had normal BMD values. The number of pregnancies was found to range from 3 to 12 (with an overall mean of 6.7 +/- 2.5), while 2.6 +/- 1.9 (range, 1-7) were miscarriages in all of the 33 postmenopausal osteoporotic women. Serum homocysteine (t-Hcy) and urinary deoxypyridinoline (DPD) levels were significantly higher in osteoporotic postmenopausal women (11.96 +/- 3.84 micromol/L, 15.4 +/- 7.0 nM/mM cr) than in non-osteoporotic postmenopausal women (10.93 +/- 3.6 micromol/L, 10.6 +/- 9.1 nM/mM cr), p pregnancies is unclear, and the relationship may only be by chance. In conclusion, the present study firstly suggests that the number of pregnancies has an effect on the t-Hcy levels. In addition, our study indicates that there is a significant negative correlation between the number of pregnancies and the lumbar spine BMD.

High-Protein Intake during Weight Loss Therapy Eliminates the Weight-Loss-Induced Improvement in Insulin Action in Obese Postmenopausal Women

Full Text Available High-protein (HP intake during weight loss (WL therapy is often recommended because it reduces the loss of lean tissue mass. However, HP intake could have adverse effects on metabolic function, because protein ingestion reduces postprandial insulin sensitivity. In this study, we compared the effects of ∼10% WL with a hypocaloric diet containing 0.8 g protein/kg/day and a hypocaloric diet containing 1.2 g protein/kg/day on muscle insulin action in postmenopausal women with obesity. We found that HP intake reduced the WL-induced decline in lean tissue mass by ∼45%. However, HP intake also prevented the WL-induced improvements in muscle insulin signaling and insulin-stimulated glucose uptake, as well as the WL-induced adaptations in oxidative stress and cell structural biology pathways. Our data demonstrate that the protein content of a WL diet can have profound effects on metabolic function and underscore the importance of considering dietary macronutrient composition during WL therapy for people with obesity.

Several studies have reported inconsistent results regarding the association between the PPARγPro12Ala polymorphism and obesity. Obese individuals had higher C-reactive protein (CRP) levels compared with those of normal weight, and PPARγ activation could significantly reduce serum high-sensitive CRP level. We have previously suggested that the Pro12Ala polymorphism represents a susceptibility factor for periodontitis, which is a known risk factor for increased CRP level. The aim was to investigate associations between PPARγ gene polymorphism, serum CRP level, BMI and/or periodontitis among post-menopausal Japanese women. The final sample in this study comprised 359 post-menopausal Japanese women. Periodontal parameters, including PD, CAL and BOP, were measured per tooth. PPARγPro12Ala genotype was determined by PCR-RFLP. Hs-CRP value was measured by a latex nephelometry assay. No significant differences in age, BMI or periodontal parameters were found between the genotypes. The percentages of sites with PD ≥ 4 mm were significantly higher among the hsCRP ≥ 1 mg/l group than the hsCRP periodontitis, serum CRP level or BMI in post-menopausal Japanese women. However, serum hsCRP level correlated with periodontitis in Ala allele carriers, and with BMI in non-carriers. © 2014 John Wiley & Sons A/S and The Gerodontology Society.

Postmenopausal Health and Disease from the Perspective of Evolutionary Medicine

Directory of Open Access Journals (Sweden)

2013-09-01

Full Text Available Menopause normally occurs between 45-55 years of age, marks the end of a woman’s reproductive lifespan, and is accompanied by a reduction in estrogen that has substantial physiological effects. The standard medical view is that these changes underlie high postmenopausal disease rates, defining menopause as an estrogen deficiency condition needing treatment. This view stems from the idea that extended postmenopausal longevity is a consequence of recent technological developments, such that women now outlive their evolutionarily-programmed physiological functional lifespan.Increasingly, however, researchers employing an evolutionary medicine framework have used data from comparative demography, comparative biology, and human behavioral ecology to challenge the mainstream medical view. Instead, these data suggest that a two-decade human postmenopausal lifespan is an evolved, species-typical trait that distinguishes humans from other primates, and has deep roots in our evolutionary past. This view rejects the inevitability of high rates of postmenopausal disease and the concept of menopause as pathology. Rather, high postmenopausal disease risk likely stems from specific lifestyle differences between industrialized societies and foraging societies of the type that dominated human evolutionary history. Women in industrialized societies tend to have higher estrogen levels during premenopausal life, and experience a greater reduction in estrogen across menopause than do women living in foraging societies, with potentially important physiological consequences. The anthropological approach to understanding postmenopausal disease risk reframes the postmenopausal lifespan as an integral period in the human life cycle, and offers alternative avenues for disease prevention by highlighting the importance of lifestyle effects on health.

The objective of this study is to investigate the effects of 12 months of dietary weight loss and/or aerobic exercise on lean mass and the measurements defining sarcopenia in postmenopausal women and to examine the potential moderating effect of serum 25-hydroxyvitamin D (25(OH)D) and age. Four hundred thirty-nine overweight and obese postmenopausal women were randomized to diet modification (N = 118), exercise (N = 117), diet + exercise (N = 117), or control (N = 87). The diet intervention was a group-based program with a 10% weight loss goal. The exercise intervention was 45 min·d, 5 d·wk, of moderate-to-vigorous intensity aerobic activity. Total and appendicular lean mass (ALM) were quantified by dual x-ray absorptiometry at baseline and 12 months. A skeletal muscle index (SMI = ALM (kg) / height (m)) and the prevalence of sarcopenia (SMI exercise significantly preserved ALM and SMI. Diet + exercise attenuated the loss of ALM and SMI compared with diet alone and did not result in significant loss of total mass or ALM compared with controls. Neither serum 25(OH)D nor age was significant moderators of the intervention effects. Aerobic exercise added to dietary weight loss can attenuate the loss of ALM during weight loss and may be effective for the prevention and treatment of sarcopenia among overweight and obese postmenopausal women.

A sensitive and specific double antibody radioimmunoassay for gonadotropin-releasing hormone (GnRH) has been developed for measurement in ethanol extracts of human plasma. Iodinated hormone was prepared with the use of the chloramine-T method, and antibodies were developed in rabbits over a six-month period with a GnRH synthetic copolymer immunogen. A Scatchard plot revealed at least three species of antibody. The assay can measure conservatively at the 5 pg. per milliliter level and shows no cross-reactivity with other available hypothalamic and pituitary hormones. The releasing hormone was quantitatively recovered from human plasma with immunologic identity to native hormone. Unextracted plasma could not be used because of nonspecific displacement. The measurement of GnRH in individuals receiving 100 μg of intravenous bolus infusions of the synthetic decapeptide show extremely elevated values with two half-lives: one of two to four minutes and another of 35 to 40 minutes. In our experiments, we have found measurable GnRH in patients with secondary amenorrhea and at the midcycle in normal women. In the normal cycling woman during the follicular and luteal phases, GnRH was undetectable. In postmenopausal women with extreme hypoestrogenism and markedly elevated luteinizing hormone values, GnRH was also undetectable. No bursts of GnRH could be detected in normal men when sampled every ten minutes over a two-hour period and every two hours throughout the day

To explore the difference in carotid intima-media thickness (CIMT) between postmenopausal women with and without osteoporosis and the risk of elevated CIMT and plaque presentation. A cross-sectional study was conducted including 46 postmenopausal women with osteoporosis and 45 non-osteoporotic postmenopausal women. CIMT was measured using B-mode ultrasound. There was no statistically significant difference in mean CIMT between postmenopausal women with osteoporosis and those without osteoporosis (p > 0.05). Risk for elevated CIMT in the osteoporosis group was comparable to that of the non-osteoporosis group (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). The risk for the presence of plaque was three times higher in osteoporotic women than in normal individuals. However, after adjusting for age and underlying diseases that would predispose the women to cardiovascular disease, there was no significant difference in terms of presence of plaque between the two groups (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). There was no difference in mean CIMT between postmenopausal women with and without osteoporosis. Risk of elevated CIMT in postmenopausal women with osteoporosis was comparable to that of postmenopausal women without osteoporosis. There was no significant difference between the two groups in terms of the presence of plaque.

Resistance training (RT) has been shown to decrease fat mass (FM), and increase fat-free mass (FFM), which can be a useful for weight loss maintenance. To examine the effects of a 1-year RT intervention on weight loss maintenance following a 6-month dietary weight loss intervention. Following a 6-month dietary weight loss intervention (-6% ± 5.8; 5.05 kg ± 4.45), 70 postmenopausal women living with overweight or obesity were randomized to a control group (n = 34) or a RT group (n = 36) (3×/week first 6 months, 2×/week last 6 months, 70-80% of 1-repetition maximum). Body composition (DXA), abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) (CT scan), resting energy expenditure (EE) (indirect calorimetry), physical activity EE and total daily EE were measured (doubly-labelled water). A total of 54 participants completed the study (control group n = 29; RT group n = 25) and compliance to the RT program was on average 64%. Significant regains were noted for body weight 0.98 (3.71) kg vs. 1.33 (3.94) kg and FM regain 1.32 (2.69) kg vs. 0.81 (3.26) kg in control and RT groups after the 1-year weight maintenance phase. No group differences were noted. Resting EE and total daily EE did not change after the weight maintenance phase, and no differences were observed between groups. Both groups had significantly greater than predicted decrease in resting EE after the 6-month dietary intervention and at the end of the 1-year weight-loss maintenance phase. Our results suggest that a 1-year RT intervention following a 6-month dietary weight loss intervention does not improve weight loss maintenance, body composition or EE in post-menopausal women living with overweight or obesity.

Obese and sedentary persons have increased risk for cancer; inflammation is a hypothesized mechanism. We examined the effects of a caloric restriction weight loss diet and exercise on inflammatory biomarkers in 439 women. Overweight and obese postmenopausal women were randomized to 1-year: caloric restriction diet (goal of 10% weight loss, N=118), aerobic exercise (225 minutes/week of moderate-to-vigorous activity, N=117), combined diet+exercise (N=117) or control (N=87). Baseline and 1-year high-sensitivity C-reactive protein (hs-CRP), serum amyloid A (SAA), interleukin-6 (IL-6), leukocyte and neutrophil levels were measured by investigators blind to group. Inflammatory biomarker changes were compared using generalized estimating equations. Models were adjusted for baseline body mass index (BMI), race/ethnicity and age. 438 (N=1 in diet+exercise group was excluded) were analyzed. Relative to controls, hs-CRP decreased by geometric mean (95% confidence interval, p-value) 0.92mg/L (0.53–1.31, Pdiet and 0.87mg/L (0.51–1.23, Pdiet+exercise groups. IL-6 decreased by 0.34pg/ml (0.13–0.55, P=0.001) in the diet and 0.32pg/ml (0.15–0.49, Pdiet+exercise groups. Neutrophil counts decreased by 0.31×109/L (0.09–0.54, P=0.006) in the diet and 0.30×109/L (0.09–0.50, P=0.005) in the diet+exercise groups. Diet and diet+exercise participants with ≥5% weight loss reduced inflammatory biomarkers (hs-CRP, SAA, and IL-6) compared to controls. The diet and diet+exercise groups reduced hs-CRP in all subgroups of baseline BMI, waist circumference, CRP level, and fasting glucose. Our findings indicate that a caloric restriction weight loss diet with or without exercise reduces biomarkers of inflammation in postmenopausal women, with potential clinical significance for cancer risk reduction.

Brown adipose tissue (BAT) is identified in mammals as an adaptive thermogenic organ for modulation of energy expenditure and heat generation. Human BAT may be primarily composed of brown-in-white (BRITE) adipocytes and stimulation of BRITE may serve as a potential target for obesity interventions. Current imaging studies of BAT detection and characterization have been mainly limited to PET/CT. MRI is an emerging application for BAT characterization in healthy children. To exploit Dixon and diffusion-weighted MRI methods to characterize cervical-supraclavicular BAT/BRITE properties in normal-weight and obese children while accounting for pubertal status. Twenty-eight healthy children (9-15 years old) with a normal or obese body mass index participated. MRI exams were performed to characterize supraclavicular adipose tissues by measuring tissue fat percentage, T2*, tissue water mobility, and microvasculature properties. We used multivariate linear regression models to compare tissue properties between normal-weight and obese groups while accounting for pubertal status. MRI measurements of BAT/BRITE tissues in obese children showed higher fat percentage (P < 0.0001), higher T2* (P < 0.0001), and lower diffusion coefficient (P = 0.015) compared with normal-weight children. Pubertal status was a significant covariate for the T2* measurement, with higher T2* (P = 0.0087) in pubertal children compared to prepubertal children. Perfusion measurements varied by pubertal status. Compared to normal-weight children, obese prepubertal children had lower perfusion fraction (P = 0.003) and pseudo-perfusion coefficient (P = 0.048); however, obese pubertal children had higher perfusion fraction (P = 0.02) and pseudo-perfusion coefficient (P = 0.028). This study utilized chemical-shift Dixon MRI and diffusion-weighted MRI methods to characterize supraclavicular BAT/BRITE tissue properties.

Although normal-weight individuals comprise a substantial minority of the binge eating disorder (BED) population, little is known about their clinical presentation. This study sought to investigate the nature and severity of eating disturbances in normal-weight adults with BED. We compared 281 normal-weight (n = 86) and obese (n = 195) treatment-seeking adults with BED (mean age = 31.0; s.d. = 10.8) on a range of current and past eating disorder symptoms using ANOVA and χ(2) analyses. After controlling for age and sex, normal-weight participants reported more frequent use of a range of healthy and unhealthy weight control behaviors compared to their obese peers, including eating fewer meals and snacks per day; exercising and skipping meals more frequently in the past month; and avoiding certain foods for weight control. They also endorsed more frequent attempts at dieting in the past year, and feeling more frequently distressed about their binge eating, at a trend level. There were no group differences in binge eating frequency in the past month, age at onset of binge eating, overvaluation of shape/weight, or likelihood of having used certain weight control behaviors (e.g., vomiting, laxative use) or having sought treatment for an eating disorder in the past. Based on our findings, normal-weight individuals appear to be a behaviorally distinct subset of the BED population with significantly greater usage of both healthy and unhealthy weight control behaviors compared to their obese peers. These results refute the notion that distress and impairment in BED are simply a result of comorbid obesity.

Although normal-weight individuals comprise a substantial minority of the binge eating disorder (BED) population, little is known about their clinical presentation. This study sought to investigate the nature and severity of eating disturbances in normal-weight adults with BED. We compared 281 normal-weight (n = 86) and obese (n = 195) treatment-seeking adults with BED (mean age = 31.0; s.d. = 10.8) on a range of current and past eating disorder symptoms using ANOVA and χ2 analyses.

The aim of this study is to correlate radiometric indices from cone beam computed tomography (CBCT) images and bone mineral density (BMD) in postmenopausal women. Quantitative CBCT indices can be used to screen for women with low BMD. Osteoporosis is a disease characterized by the deterioration of bone tissue and the consequent decrease in BMD and increase in bone fragility. Several studies have been performed to assess radiometric indices in panoramic images as low-BMD predictors. The aim of this study is to correlate radiometric indices from CBCT images and BMD in postmenopausal women. Sixty postmenopausal women with indications for dental implants and CBCT evaluation were selected. Dual-energy X-ray absorptiometry (DXA) was performed, and the patients were divided into normal, osteopenia, and osteoporosis groups, according to the World Health Organization (WHO) criteria. Cross-sectional images were used to evaluate the computed tomography mandibular index (CTMI), the computed tomography index (inferior) (CTI (I)) and computed tomography index (superior) (CTI (S)). Student's t test was used to compare the differences between the indices of the groups' intraclass correlation coefficient (ICC). Statistical analysis showed a high degree of interobserver and intraobserver agreement for all measurements (ICC > 0.80). The mean values of CTMI, CTI (S), and CTI (I) were lower in the osteoporosis group than in osteopenia and normal patients (p < 0.05). In comparing normal patients and women with osteopenia, there was no statistically significant difference in the mean value of CTI (I) (p = 0.075). Quantitative CBCT indices may help dentists to screen for women with low spinal and femoral bone mineral density so that they can refer postmenopausal women for bone densitometry.

We examined the socio-economic differential in the self-perception of body weight, future intention for weight management and actual weight-management behaviour among normal-weight, overweight and obese women in India. A population-based follow-up survey of ever-married women, systematically selected from the second round of the National Family Health Survey (NFHS-2, 1998-99) samples, who were re-interviewed after four years in 2003. Information on women's perception about their own weight, intention of weight management and actual weight-management behaviour were collected through personal interview. Anthropometric measurements were obtained from women to compute their current BMI. Three hundred and twenty-five ever-married women aged 20-54 years residing in the national capital territory of Delhi in India. Discrepancy between self-perceived body weight and women's actual body weight was reported. One-quarter of overweight women and one in ten obese women perceived themselves as normal weight. Although a majority of overweight and obese women wanted to reduce their weight, a significant proportion of overweight (one in four) and 4 % of obese women also wanted to maintain their weight as it is. Only one in three overweight and one in four obese women were performing any physical activity to reduce their weight. These findings are important for public health interventions in obesity care. Implementation of health promotion and health education in the community should use effective school education and mass-media programmes to raise awareness of appropriate body weight to combat the growing level of obesity among Indian women.

Polycystic ovary syndrome (PCOS) is an endocrine disease closely related to several risk factors of cardiovascular disease. Obese women with PCOS show altered autonomic modulation. The results of studies investigating cardiac autonomic functions of normal-weight women with PCOS are conflicting. The aim of the study was to assess the reactivity of cardiac sympathovagal balance in normal-weight women with PCOS by heart rate variability analysis. We examined the heart rate variability in 60 normal-weight women with PCOS and compared them with that in 60 age-matched healthy women having a similar metabolic profile. Time and frequency domain parameters of heart rate variability were analyzed based on 5-min-long continuous electrocardiography recordings for the following 3 periods: (1) during rest in supine position, (2) during controlled breathing, and (3) during isometric handgrip exercise. Time and frequency domain parameters of heart rate variability for the 3 periods assessed were similar in the two groups. Although modified Ferriman-Gallwey score and serum testosterone and luteinizing hormone levels were significantly higher in women with PCOS, homeostatic model assessment-insulin resistance (HOMA-IR) was not different the between the PCOS and control groups. There were no significant correlations between serum testosterone levels and heart rate variability parameters among the study population. The findings of this study suggest that the reactivity of cardiac sympathovagal balance is not altered in normal-weight women with PCOS having a normal HOMA-IR.

To investigate differences in physical activity and attitude toward physical activity in adolescents with different degrees of overweight and explore whether the prediction of physical activity by attitude is moderated by level of overweight. Subjects were divided into a normal-weight group (n = 37, 18.8 +/- 1.2 kg/m2), an overweight group (n = 28, 25.9 +/- 1.3 kg/m2), and an obese group (n = 24, 33.7 +/- 4.1 kg/m2). Mean age was 14.6 +/- 1.2 years, with 72% girls. Physical activity was estimated using the Baecke Questionnaire. Attitude was measured by assessing perceived benefits and barriers. Participation in sports was higher in normal-weight compared with overweight (p attitude compared with their normal-weight (p attitude was not moderated by level of overweight. This study demonstrates that overweight and obese adolescents show lower sport participation and have a less positive attitude toward physical activity. Interventions in youngsters with weight problems should try to increase participation in sports by making activities more fun and attractive for these youngsters.

There has been limited research about disordered eating in middle-aged women, and to date, few data exist about restrained eating behavior in postmenopausal women. Therefore, the aim of this study was to examine eating behavior with a specific focus on menopause as an associated factor in restrained eating. Beyond this, we were interested in how postmenopausal status and self-esteem would interact to determine eating patterns in women in middle age. We conducted an online survey in women aged between 40 and 66. Eating behavior was assessed with the Eating Disorder Examination-Questionnaire (EDE-Q) in premenopausal (N = 318) and postmenopausal women (N = 250). All participants rated their self-esteem using the Rosenberg Self-Esteem Scale (RSE) and reported their weight, height, waist circumference, and hip circumference. 15.7% of all participants showed clinically meaningful scores on restrained eating. Postmenopausal women showed significantly higher scores on the EDE-Q subscale of restrained eating as compared to premenopausal women, but when controlling for body mass index, however, this finding was no longer significant. Further exploratory analyses suggest that particularly low or high self-esteem levels are associated with restrained eating. Self-esteem might serve as a mediator between menopausal status and restrained eating, however results of these additional analyses were inconsistent. Restrained eating may appear in middle-aged women. Particularly in postmenopausal women, restrained eating might be associated with lower and higher self-esteem.

Intuitionistic Fuzzy Normalized Weighted Bonferroni Mean and Its Application in Multicriteria Decision Making

Full Text Available The Bonferroni mean (BM was introduced by Bonferroni six decades ago but has been a hot research topic recently since its usefulness of the aggregation techniques. The desirable characteristic of the BM is its capability to capture the interrelationship between input arguments. However, the classical BM and GBM ignore the weight vector of aggregated arguments, the general weighted BM (WBM has not the reducibility, and the revised generalized weighted BM (GWBM cannot reflect the interrelationship between the individual criterion and other criteria. To deal with these issues, in this paper, we propose the normalized weighted Bonferroni mean (NWBM and the generalized normalized weighted Bonferroni mean (GNWBM and study their desirable properties, such as reducibility, idempotency, monotonicity, and boundedness. Furthermore, we investigate the NWBM and GNWBM operators under the intuitionistic fuzzy environment which is more common phenomenon in modern life and develop two new intuitionistic fuzzy aggregation operators based on the NWBM and GNWBM, that is, the intuitionistic fuzzy normalized weighted Bonferroni mean (IFNWBM and the generalized intuitionistic fuzzy normalized weighted Bonferroni mean (GIFNWBM. Finally, based on the GIFNWBM, we propose an approach to multicriteria decision making under the intuitionistic fuzzy environment, and a practical example is provided to illustrate our results.

The pathogenesis of asthma in the context of excess body weight may be distinct from asthma that develops in normal weight children. The study's objective was to explore the biology of asthma in the context of obesity and normal weight status using genetic methodologies. Associations between asthma and SNPs in 49 genes were assessed, as well as, interactions between SNPs and overweight status in child participants of the Greater Cincinnati Pediatric Clinic Repository. Asthma was significantly associated with weight (OR = 1.38; P = 0.037). The number of genes and the magnitude of their associations with asthma were notably greater when considering overweight children alone vs normal weight and overweight children together. When considering weight, distinct sets of asthma-associated genes were observed, many times with opposing effects. We demonstrated that the underlying heterogeneity of asthma is likely due in part to distinct pathogenetic pathways that depend on preceding/comorbid overweight and/or allergy. It is therefore important to consider both obesity and asthma when conducting studies of asthma. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Low body mass index (BMI) is a well-established risk factor for fracture in postmenopausal women. Height and obesity have also been associated with increased fracture risk at some sites. We investigated the relationships of weight, BMI, and height with incident clinical fracture in a practice-based cohort of postmenopausal women participating in the Global Longitudinal study of Osteoporosis in Women (GLOW). Data were collected at baseline and at 1, 2, and 3 years. For hip, spine, wrist, pelvis, rib, upper arm/shoulder, clavicle, ankle, lower leg, and upper leg fractures, we modeled the time to incident self-reported fracture over a 3-year period using the Cox proportional hazards model and fitted the best linear or nonlinear models containing height, weight, and BMI. Of 52,939 women, 3628 (6.9%) reported an incident clinical fracture during the 3-year follow-up period. Linear BMI showed a significant inverse association with hip, clinical spine, and wrist fractures: adjusted hazard ratios (HRs) (95% confidence intervals [CIs]) per increase of 5 kg/m(2) were 0.80 (0.71-0.90), 0.83 (0.76-0.92), and 0.88 (0.83-0.94), respectively (all p fractures, linear weight showed a significant positive association: adjusted HR per 5-kg increase 1.05 (1.02-1.07) (p fractures, only linear height was significantly associated: adjusted HRs per 10-cm increase were 0.85 (0.75-0.97) (p = 0.02) and 0.73 (0.57-0.92) (p = 0.009), respectively. For pelvic and rib fractures, the best models were for nonlinear BMI or weight (p = 0.05 and 0.03, respectively), with inverse associations at low BMI/body weight and positive associations at high values. These data demonstrate that the relationships between fracture and weight, BMI, and height are site-specific. The different associations may be mediated, at least in part, by effects on bone mineral density, bone structure and geometry, and patterns of falling. © 2014 American Society for Bone and Mineral Research.

Purpose To investigate the effects of 12 months of dietary weight loss and/or aerobic exercise on lean mass and the measurements defining sarcopenia in postmenopausal women, and to examine the potential moderating effect of serum 25-hydroxyvitamin D (25(OH)D) and age. Methods 439 overweight and obese postmenopausal women were randomized to: diet modification (N=118); exercise (N=117), diet+exercise (N=117), or control (N=87). The diet intervention was a group-based program with a 10% weight loss goal. The exercise intervention was 45 mins/day, 5 days/week of moderate-to-vigorous intensity aerobic activity. Total and appendicular lean mass were quantified by dual Xray absorptiometry (DXA) at baseline and 12 months. A skeletal muscle index (SMI=appendicular lean mass (kg)/m2) and the prevalence of sarcopenia (SMIlean mass, and a borderline significant decrease in appendicular lean mass and SMI compared to controls. In contrast, aerobic exercise significantly preserved appendicular lean mass and SMI. Diet + exercise attenuated the loss of appendicular lean mass and SMI compared to diet alone, and did not result in significant loss of total- or appendicular lean mass compared to controls. Neither serum 25(OH)D nor age were significant moderators of the intervention effects. Conclusions Aerobic exercise added to dietary weight loss can attenuate the loss of appendicular lean mass during weight loss, and may be effective for the prevention and treatment of sarcopenia among overweight and obese postmenopausal women.

Purpose: To assess the predisposing factors and clinical characteristics of pelvic insufficiency fractures (PIF) in postmenopausal women with pelvic irradiation. Material and methods: A total 335 postmenopausal patients with cervical cancer of the intact uterus treated with radiation therapy between 1983 and 1998 were reviewed. Total external dose was delivered between 45 and 50.4 Gy with parallel opposed anteroposterior portals. Total brachytherapy dose at point A was delivered between 10 and 36 Gy. PIF were diagnosed by bone scintigraphy and confirmed by computed tomography. The cumulative incidence of symptomatic PIF was estimated by actuarial methods. Potential risk factors (age, weight, type II diabetes, delivery, menopause, total external dose, total brachytherapy dose) were assessed. Results: Fifty-seven (17.0%) of 335 patients were diagnosed as having PIF. Forty-seven patients were symptomatic and ten were asymptomatic. Parameters carrying a significant association with PIF were body weight 49 kg or below (P=0.044) in stepwise logistic regression analysis. The cumulative incidence of symptomatic PIF at 5 years was 17.9% calculated by the Kaplan-Meier method. A body weight of 49 kg or below and more than three deliveries were identified as having a significant effect on symptomatic PIF in univariate analysis (P=0.021, P=0.003, log-rank test) and Cox life table regression analysis (P=0.038, P=0.013). Five patients required narcotic agents and eight patients required hospital admission. Conclusions: We should consider reducing the dose contribution to the sacrum and sacroilac joints, without underdosing the tumor, especially in postmenopausal women with many deliveries or low body weight

There are many health risks involved with the use of weight loss products by normal weight women. The mass media may compound this problem through the promotion of weight loss products and a thin body size. This study tested women's perceptions of different weight loss product ads to determine if body dysphoria (i.e., an over concern with body size and shape in normal weight people) was associated with risk beliefs, past behaviors, and intention toward using weight loss products. Normal weight women (age range = 18-41 yr), who were classified as either high (n=45) or low (n=43) on a measure of body dysphoria, rated different weight loss products according to their perception of health risks, past behavior, and their intention to consume the products. These products were a dietary fat substitute (olestra), a prescription obesity medication (sibutramine), and an over-the-counter appetite suppressant (phenylpropanolamine). High body dysphoric women reported higher intentions to use the products as well as increased prior use of two of the three weight loss products. High body dysphoric women did not believe that these weight loss products were harmless. They recognized potential health risks associated with using such products, but nonetheless, expressed intention to use these weight loss products at a higher frequency. Also, several variables related to body image were found to effectively discriminate normal weight women at risk for abusing weight loss products. This study found that women who do not need to lose weight but have significant body image concerns were willing to use potentially harmful weight loss products despite the knowledge that such products might pose significant health risks. Techniques utilized by advertising regulatory agencies such as warning labels did not have a strong deterrent effect for stated intentions to use the products. Implications of these findings for public health policy issues were discussed.

Probiotics in the Prevention and Treatment of Postmenopausal Vaginal Infections: Review Article

Park, Yoo Jin

2017-01-01

Bacterial vaginosis (BV) and complicated vulvovaginal candidiasis (VVC) are frequently occurring vaginal infections in postmenopausal women, caused by an imbalance in vaginal microflora. Postmenopausal women suffer from decreased ovarian hormones estrogen and progesterone. A normal, healthy vaginal microflora mainly comprises Lactobacillus species (spp.), which act beneficially as a bacterial barrier in the vagina, interfering with uropathogens. During premenopausal period, estrogen promotes vaginal colonization by lactobacilli that metabolizing glycogen and producing lactic acid, and maintains intravaginal health by lowering the intravaginal pH level. A lower vaginal pH inhibits uropathogen growth, preventing vaginal infections. Decreased estrogen secretion in postmenopausal women depletes lactobacilli and increases intravaginal pH, resulting in increased vaginal colonization by harmful microorganisms (e.g., Enterobacter, Escherichia coli, Candida, and Gardnerella). Probiotics positively effects on vaginal microflora composition by promoting the proliferation of beneficial microorganisms, alters the intravaginal microbiota composition, prevents vaginal infections in postmenopausal. Probiotics also reduce the symptoms of vaginal infections (e.g., vaginal discharge, odor, etc.), and are thus helpful for the treatment and prevention of BV and VVC. In this review article, we provide information on the intravaginal mechanism of postmenopausal vaginal infections, and describes the effectiveness of probiotics in the treatment and prevention of BV and VVC.

Postmenopausal women are at increased risk for osteoporosis and obesity due to changes in hormones. The relationship between osteoporosis and body weight is known, and its relation with body fat mass is discussed. The purpose of this study was to evaluate the bone mineral density(BMD) changes of epicardial adipose tissue(EAT) and abdominal subcutaneous fat. The subjects of this study were 160 postmenopausal women who underwent BMD and echocardiography. The thickness of the epicardial adipose tissue was measured in three sections and the BMD were meassured according to the diagnostic criteria. The results of this study that age increase the risk of osteoporosis increases, and as the weight and BMI decrease, the risk of osteoporosis increases(p<0.05). The relationship between changes in bone mineral density and adipose tissue in postmenopausal women, increased epicardial adipose tissue was negatively correlated with the bone mineral density(p<0.05). conversely, increased abdominal subcutaneous fat thickness was positively correlated with bone mineral density(p<0.05). In other words, the effect of bone mineral density on the location of adipose tissue was different. If Echocardiography is used to periodically examine changes in the thickness of the epicardial adipose tissue, it may be prevented before proceeding to osteoporosis.

Normal weight obesity is defined as having excessive body fat, but normal BMI. Even though previous research revealed that excessive body fat in children inhibited their physical activity and decreased motor performance, there has been only little evidence about motor performance of normal weight obese children. This study aims to establish whether normal weight obese pre-school children aged 3-6 years will have a significantly worse level of fundamental motor skills compared to normal weight non-obese counterparts. The research sample consisted of 152 pre-schoolers selected from a specific district of Prague, the Czech Republic. According to values from four skinfolds: triceps, subscapula, suprailiaca, calf, and BMI three categories of children aged 3-6 years were determined: A) normal weight obese n = 51; B) normal weight non-obese n = 52; C) overweight and obese n = 49. The Movement Assessment Battery for Children (MABC-2) was used for the assessment of fundamental motor skills. Normal weight obese children had significantly higher amount of adipose tissue p < 0.001 than normal weight non-obese children but the same average BMI. Moreover, normal weight obese children did not have significantly less amount of subcutaneous fat on triceps and calf compared to their overweight and obese peers. In majority of MABC-2 tests, normal weight obese pre-schoolers showed the poorest performance. Moreover, normal weight obese children had significantly worse total standard score = 38.82 compared to normal weight non-obese peers = 52.27; p < 0.05. In addition, normal weight obese children had a more than three times higher frequency OR = 3.69 CI95% (1.10; 12.35) of severe motor deficit performance ≤ 5 th centile of the MABC-2 norm. These findings are strongly alarming since indices like BMI are not able to identify normal weight obese individual. We recommend verifying real portion of normal weight obese children as they are probably in higher risk of health and motor

Full Text Available The aims of the present study were to assess the volume of physical activity (PA throughout pregnancy in normal-weight vs overweight/obese women, and to investigate which factors may predict compliance to PA recommendations in these women throughout gestation. In 236 pregnant women, 177 normal-weight and 59 overweight/obese (median[IQR] BMI 21.2[19.9-22.8] vs 26.5[25.5-29.0] kg/m2, respectively, medical history, anthropometry and clinical data, including glucose tolerance, were recorded. In addition, pre-pregnancy PA was estimated by the Kaiser questionnaire, while total, walking and fitness/sport PA during pregnancy were assessed by the Physical Activity Scale for the Elderly (PASE modified questionnaire, at 14-16, 24-28 and 30-32 weeks of gestation. PA volume was very low in the first trimester of pregnancy in both groups of women. However, it increased in the second and third trimester in normal-weight, but not in overweight/obese subjects. Higher pre-pregnancy PA was a statistically significant predictor of being physically active (>150 minutes of PA per week during all trimesters of gestation. In conclusion, physical activity volume is low in pregnant women, especially in overweight/obese subjects. PA volume increases during pregnancy only in normal-weight women. Pre-pregnancy PA is an independent predictor of achieving a PA volume of at least 150 min per week during pregnancy.

Osteoporosis remains a major health problem in all developed countries and is a condition in which several dietary factors have been implicated. To assess the nutritional status and levels of adiposity of postmenopausal women in relation to bone mineral density. A cross-sectional study in which dietary intake was estimated by a food frequency questionnaire in 300 Saudi postmenopausal women aged 46-88 years. Bone profile biochemistry (serum calcium, phosphate, parathyroid hormone [PTH], vitamin D) and bone mineral density (BMD) in 3 skeletal sites were determined for all participants. Overweight and obesity were highly prevalent among the study population. No significant correlation was found between dietary calcium and vitamin D and bone mass at any site. Dietary intake of calcium and vitamin D was significantly less than the recommended levels for a large proportion of the cohort. Energy-adjusted intakes of carbohydrates, fat, protein, and unsaturated fatty acids were associated with BMD in the postmenopausal women. Age, body weight, and residency type were predictors of BMD at all sites. Serum-intact PTH was a predictor of BMD at lumbar spine and femoral neck. Waist : hip ratio (WHR) was a predictor for BMD at femoral neck. These results suggest that BMD is influenced by dietary factors other than calcium and vitamin D. However, nondietary factors such as age, WHR, PTH, and body weight may be important determinants of BMD in postmenopausal women.

Objective Research shows that slower habituation of salivary responses to food stimuli is related to greater energy intake and that obese (Ob) individuals habituate slower than those of normal weight (NW). No study has examined habituation rates in weight loss maintainers (WLMs) who have reduced from obese to normal weight, relative to those who are Ob or NW. Design Salivation to two baseline water trials and 10 lemon-flavored lollipop trials were studied in 14 WLMs, 15 Ob and 18 NW individuals comparable in age, gender and ethnicity. Linear mixed models were used to compare WLMs with Ob and NW groups. Results Salivation in the WLM and NW groups decreased significantly (for both P <0.005) across trials, indicative of habituation. Salivary responses in the Ob group did not habituate (P=0.46). When compared with Ob group, WLMs showed a quicker reduction in salivation (P<0.05). WLM and NW groups did not differ in habituation rate (P=0.49). Conclusions WLMs have habituation rates that are comparable to NW individuals without previous history of obesity, and show quicker habituation than those who are currently obese. These results suggest that physiological responses to food may ‘normalize’ with successful weight loss maintenance. PMID:20010900

Objective To determine, among children with normal birth weight, if maternal hyperglycemia and weight gain independently increase childhood obesity risk in a very large diverse population. Methods Study population was 24,141 individuals (mothers and their normal birth weight offspring, born 1995-2003) among a diverse population with universal GDM screening [50-g glucose-challenge test (GCT); 3 h. 100 g oral glucose tolerance test (OGTT) if GCT+]. Among the 13,037 full-term offspring with normal birth weight (2500-4000 g), annual measured height/weight was ascertained between ages 2 and 10 years to calculate gender-specific BMI-for-age percentiles using USA norms (1960-1995 standard). Results Among children who began life with normal birth weight, we found a significant trend for developing both childhood overweight (>85 %ile) and obesity (>95 %ile) during the first decade of life with both maternal hyperglycemia (normal GCT, GCT+ but no GDM, GDM) and excessive gestational weight gain [>40 pounds (18.1 kg)]; p maternal glucose and/or weight gain effects to imprint for childhood obesity in the first decade remained after adjustment for potential confounders including maternal age, parity, as well as pre-pregnancy BMI. The attributable risk (%) for childhood obesity was 28.5 % (95 % CI 15.9-41.1) for GDM and 16.4 % (95 % CI 9.4-23.2) for excessive gestational weight gain. Conclusions for Practice Both maternal hyperglycemia and excessive weight gain have independent effects to increase childhood obesity risk. Future research should focus on prevention efforts during pregnancy as a potential window of opportunity to reduce childhood obesity.

The fruit of Lycium chinense Miller (Solanaceae) is used as a functional food and a medicinal herb for treating many specific health concerns. Weight gain induced by estrogen deficiency is a problem for post-menopausal women around the globe. The present study investigates the effects of aqueous extract of L. chinense (LC) on post-menopausal obesity. Female C57BL/6 mice were ovariectomized and fed on high-fat diet (HFD) for 12 weeks to induce post-menopausal obesity. LC extract (1[Formula: see text]mg/kg and 10[Formula: see text]mg/kg) was orally administrated for 6 weeks with continuous HFD feeding. Ovarian adipose tissues and uterus were weighed. Serum triglyceride, cholesterol, LDL-cholesterol and fasting glucose levels were analyzed. The expressions of adipocyte-specific factors and estrogen receptors (ERs) were investigated. Additionally, lipid accumulation was confirmed in differentiated 3T3-L1 adipocytes. Increased body weight due to post-menopausal obesity was ameliorated about 14.7% and 17.76% by treatment of 1[Formula: see text]mg/kg and 10[Formula: see text]mg/kg LC, respectively. LC treatment reduced both of serum lipid and fasting blood glucose levels. Adipocyte hypertrophy and fatty liver were ameliorated in LC-treated groups. In LC-treated adipocyte cells, lipid accumulation was significantly inhibited. The expression of perilipin in adipose tissues was decreased by LC. In addition, expression of PPAR-[Formula: see text] protein was down-regulated in adipose tissues and differentiated adipocytes, while GLUT4 expression was increased in adipose tissues by LC treatment. Moreover, LC treatment up-regulated the expressions of ER-[Formula: see text]/[Formula: see text] accompanied with increased uterine weight. These results showed the ameliorative effects of LC on overweight after menopause. Post-menopausal obesity may be improved by LC treatment.

To evaluate the recurrence rate of high-grade squamous intraepithelial lesions in postmenopausal women previously submitted to laser CO2 conization and the role of persistent oncogenic HPV types. Fifty-five patients with a cytological diagnosis of high-grade squamous intraepithelial lesions were triaged with a standard colposcopy. Hormonal replacement therapy was considered as significative in influencing cervical trophism. Vaginal smears for microbiological examination were obtained. H-R HPV test was performed by PCR. The follow-up checks including cytology, colposcopy and HVP test were performed for a minimum of 5 years. Histological analysis revealed 19 CIN2 (cervical intraepithelial lesions) and 36 CIN3 lesions. The cumulative failure rate at first treatment was 14%. HPV test was positive for HPV 16 type in all patients. Forty-two patients during the follow up checks resulted negative to cytology, colposcopy and HR HPV test. At the one-year follow-up check, 7 patients revealed normal cytological and abnormal colposcopical findings and persistent positive HR HPV test. At the five-year follow-up check, 14 patients with a normal cytological smear had a recurrence of CIN2/3 and positive HR HPV test. In postmenopause, the correct management of H-R squamous intraepithelial lesions is still debated. However, a satisfactory follow-up is the main requirement for the conservative management. HPV typing in the follow-up is important to detect persistent types to identify women at risk of developing cervical abnormalities. The incidence of cervical neoplasia does not decrease with increasing age. Since HPV positivity predicted subsequent infection, testing postmenopausal patients for the virus may be a cost-effective method of disease prevention.

Previous research has indicated that both boys and girls strive for a slim body, with boys having an additional focus on a muscular body build. The current study was designed to evaluate the utility of a biopsychosocial model to explain body image and body change strategies among children. The study evaluated changes over time in body image and strategies to lose weight and increase muscles among 132 normal weight and 67 overweight boys (mean age = 9.23 years) and 158 normal weight and 55 overweight girls (mean age = 9.33 years). The predictive role of BMI, positive and negative affect, self-esteem and perceived sociocultural pressures to lose weight or increase muscle on body image and body change strategies over a 16 month period was evaluated. All participants completed the questionnaire on both occasions. The results demonstrated that both overweight boys and girls were more likely to be dissatisfied with their weight, place more importance on their weight, engage in more strategies to lose weight as well as perceive more pressure to lose weight. Overweight boys and girls were also more likely to report lower levels of self-esteem and positive affect, and higher levels of negative affect, and reported a reduction in their self-esteem over time. Regression analyses demonstrated that among overweight boys, low self-esteem and high levels of perceived pressure to lose weight predicted weight dissatisfaction; for overweight girls, weight dissatisfaction was also predicted by low levels of self-esteem. The implication of these findings in terms of factors contributing to the adoption of health risk behaviors among children is discussed.

To assess the prevalence of osteopenia and osteoporosis among Saudi postmenopausal women with non-insulin dependent type-2 diabetes mellitus (T2DM). The study was carried out at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from February 2000 to September 2002. bone mineral density (BMD) of lumbar spine and femoral neck using dual x-ray absorptionmetry (DXA; Lunar Wisconsin), were performed in 104 postmenopausal Saudi women with T2DM and 101postmenopausal non-diabetic women (control). Bone mineral density was measured in gm/cm and both T-score and Z-score were measured but only T-score ws used for analysis based on World Health Organization criteria. Bone profile, 25(OH) Vitamin D, 1.25(OH) Vitamin D, parathyroid harmone and urine deoxypyridinoline (DPD) were measured in both patients and controls. Body fit fat measurement aruond the biceps muscles using Futrex (body compostion analyzer) were performed in patients and controls. Years postmenopausal, duration of diabetes mellitus, parity, exercise, sun exposure and milk consumption were also recorded. In the diabetic group, the mean spine BMD was 0.928 gm/cm (T-score=2.28 SD) and for femoral neck the mean BMD was 0.817 gm/cm (T-score=-1.21SD). In control group, the mean spine BMD was 1.036 gm/cm (T-score=-1.2) and mean femoral neck BMD was 0.914 gm/cm (T-score=-0.608). In the diabetic group, there was 16(16.64%)patients with normal BMD of the spine, 42 patients (43.68%) with ostopenia (mean T-score=-1.8SD) and 45 (46.8%) with osteoporosis (mean T-score=-3.3 SD). Osteoporosis is most common among Type2 postmenopausal females in this ethnic group. Since both groups are postmenopausal, having equal percentage of Vitamin D deficiency, multi-parity, non exposure sun, lack of excercise and negligible milk intake, one can conlude that low BMD can be attributed to DM in the absence of other cause of osteoporosis.

To examine the change in breastfeeding behaviors over time, among low birth weight (LBW), very low birth weight (VLBW), and normal birth weight (NBW) infants using nationally representative US data. Univariate statistics and bivariate logistic models were examined using the Early Child Longitudinal Study-Birth Cohort (2001) and National Study of Children's Health (2007 and 2011/2012). Breastfeeding behaviors improved for infants of all birth weights from 2007 to 2011/2012. In 2011/2012, a higher percentage of VLBW infants were ever breastfed compared with LBW and NBW infants. In 2011/2012, LBW infants had a 28% lower odds (95% CI, 0.57-0.92) of ever breastfeeding and a 52% lower odds (95% CI, 0.38-0.61) of breastfeeding for ≥6 months compared with NBW infants. Among black infants, a larger percentage of VLBW infants were breastfed for ≥6 months (26.2%) compared with LBW infants (14.9%). Breastfeeding rates for VLBW and NBW infants have improved over time. Both VLBW and NBW infants are close to meeting the Healthy People 2020 ever breastfeeding goal of 81.9%. LBW infants are farther from this goal than VLBW infants. The results suggest a need for policies that encourage breastfeeding specifically among LBW infants. Copyright © 2018 Elsevier Inc. All rights reserved.

Franco, Lana P; Morais, Carla C; Cominetti, Cristiane

2016-09-01

The growing concern about the impact of overweight on health has led to studies that shed light on types of obesity other than the classic model based on body mass index. Normal-weight obesity syndrome is characterized by excess body fat in individuals with adequate body mass index (18.5-24.9 kg/m(2)). This condition increases the risk of cardiovascular morbidity and mortality and other conditions associated with chronic diseases, such as insulin resistance, hypertension, and dyslipidemia. The aims of this review are to define the diagnostic criteria for normal-weight obesity syndrome and to examine the risks associated with this condition in order to promote preventive measures and early treatment for affected individuals. © The Author(s) 2016.

Full Text Available Operator theory is an important research content of the analytic function space theory. The discussion of simultaneous operator and function space is an effective way to study operator and function space. Assuming that  is an analytic self map on the unit disk Δ, and the normal weighted bloch space μ-B is a Banach space on the unit disk Δ, defining a composition operator C∶C(f=f on μ-B for all f∈μ-B, integral type operator JhC and CJh are generalized by integral operator and composition operator. The boundeness and compactness of the integral type operator JhC acting from normal weighted Bloch spaces to QT,S spaces are discussed, as well as the boundeness of the integral type operators CJh acting from normal weighted Bloch spaces to QT,S spaces. The related sufficient and necessary conditions are given.

We examined whether men and women with obesity reported different types of discrimination to a greater extent than those with normal weight, and explored whether these associations were modified by socioeconomic position. National representative sample of men and women, with normal weight (n = 2,000), moderate obesity (n = 2,461) and severe obesity (n = 557). Participants were identified in a yearly population-based survey (1996-2006) and data on perceived discrimination and potential confounding factors were measured in 2008. Logistic regression models tested whether obesity was associated with perceived lifetime, workplace, healthcare and interpersonal discrimination. The overall response rate was 56%. For men, moderate obesity was associated with workplace discrimination, while severely obese women were more likely to report this sort of discrimination than normal weight women. Severely obese individuals were twice as likely to report healthcare discrimination than normal weight individuals. Women, regardless of weight status group, were in turn twice as likely to report healthcare discrimination as men. Women with severe obesity were significantly more likely to report interpersonal discrimination compared with normal weight women. Socioeconomic position modified the association between weight status and healthcare discrimination. Highly educated individuals with moderate and severe obesity were more likely to report healthcare discrimination than their normal weight counterparts, whereas low educated individuals with normal weight, moderate and severe obesity were equally likely to report discrimination. In this large, population-based study, discrimination was more likely to be reported by obese individuals compared with those of normal weight. The associations, however, varied according to gender and socioeconomic position.

Full Text Available Abstract Background The relationship between BMI and leptin has been studied extensively in the past, but previous reports in postmenopausal women have not been conducted under carefully controlled dietary conditions of weight maintenance using precise measures of body fat distribution. The aim of the present study was to examine the association between serum leptin concentration and adiposity as estimated by BMI and dual energy x-ray absorptiometry (DEXA measures (percent body fat, central and peripheral fat, and lean mass in postmenopausal women. Methods This study was conducted as a cross-sectional analysis within the control segment of a randomized, crossover trial in which postmenopausal women (n = 51 consumed 0 (control, 15 (one drink, and 30 (two drinks g alcohol (ethanol/d for 8 weeks as part of a controlled diet. BMIs were determined and DEXA scans were administered to the women during the 0 g alcohol treatment, and a blood sample was collected at baseline and week 8 of each study period for leptin analysis. Results and discussion In multivariate analysis, women who were overweight (BMI > 25 to ≤ 30 kg/m2 had a 2-fold increase, and obese women (BMI > 30 kg/m2 had more than a 3-fold increase in serum leptin concentrations compared to normal weight (BMI ≤25 kg/m2 women. When the models for the different measures of adiposity were assessed by multiple R2, models which included percent body fat explained the highest proportion (approximately 80% of the serum leptin variance. Conclusion Under carefully controlled dietary conditions, we confirm that higher levels of adiposity were associated with higher concentrations of serum leptin. It appears that percent body fat in postmenopausal women may be the best adiposity-related predictor of serum leptin.

To investigate associations among methods for noninvasive measurement of skeletal bone mass, we studied 40 healthy early postmenopausal women and 68 older postmenopausal women with osteoporosis. Methods included single- and dual-energy quantitative computed tomography (QCT) and dual-photon absorptiometry (DPA) of the lumbar spine, single-photon absorptiometry (SPA) of the distal third of the radius, and combined cortical thickness (CCT) of the second metacarpal shaft. Lateral thoracolumbar radiography was performed, and a spinal fracture index was calculated. There was good correlation between QCT and DPA methods in early postmenopausal women and modest correlation in postmenopausal osteoporotic women. Correlations between spinal measurements (QCT or DPA) and appendicular cortical measurements (SPA or CCT) were modest in healthy women and poor in osteoporotic women. Measurements resulting from one method are not predictive of those by another method for the individual patient. The strongest correlation with severity of vertebral fracture is provided by QCT; the weakest, by SPA. There was a high correlation between single- and dual-energy QCT results, indicating that errors due to vertebral fat are not substantial in these postmenopausal women. Single-energy QCT may be adequate and perhaps preferable for assessing postmenopausal women. The measurement of spinal trabecular bone density by QCT discriminates between osteoporotic women and younger healthy women with more sensitivity than measurements of spinal integral bone by DPA or of appendicular cortical bone by SPA or CCT

Obese postmenopausal women have a 50% higher risk of breast cancer than non-obese women. There is not an animal model that mimics postmenopausal obesity related to breast cancer progression. Using age-relevant C57BL/6 mice, this study determined whether postmenopausal obesity increases VEGF expression, tumor angiogenesis, and breast tumor growth. Ovariectomy (OVX) was performed in 12 sixty week-old female mice, then followed by a low-fat (5%, LF, n=6) or a high-fat (60%, HF, n=6) diet for 12 weeks. In the eighth week of the dietary program, 10(6) E0771 (mouse breast cancer) cells were injected in the left fourth mammary gland. Tumor size was monitored for 4 weeks. Body weights were monitored weekly. At the end of the experiment, blood samples, visceral fat and tumors were collected for measuring VEGF expression using ELISA and intratumoral microvessel density (IMD) using CD31 immunochemistry. Body weight was significantly increased in OVX/HF mice, compared to OVX/LF group (55.3±1.7 vs. 41.5±1.5 g; p < 0.01). There was a two-fold increase in the ratio of visceral fat/BW in OVX/HF mice, compared to those in OVX/LF group (0.062±0.005 vs. 0.032±0.003; p < 0.01). Postmenopausal obesity significantly increased breast tumor weight over the control (4.62±0.63 vs. 1.98±0.27 g; p < 0.01) and IMD (173±3.7 vs. 139±4.3 IM#/mm^2; p < 0.01). Tumor VEGF levels were higher in OVX/HF mice, compared to OVX/LF group (73.3±3.8 vs. 49.5±4.3 pg/mg protein; p < 0.01). Plasma VEGF levels (69±7.1 vs. 48±3.5 pg/ml) and visceral fat VEGF levels (424.4±39.5 vs. 208.5±22.4 pg/mg protein) were significantly increased in OVX/HF mice, compared to OVX/LF group, respectively (n=6; p < 0.01). Interestingly, adipose tissue primary culture showed that subcutaneous fat released more VEGF, compared to visceral fat (6.77±1.14 vs. 0.94±0.16 pg/mg tissue; n=6; p < 0.01). These findings support the hypothesis that postmenopausal obesity promotes tumor angiogenesis and breast cancer

The assessment of osteoporosis risk factors can help guide early intervention. The objective of this study was to analyze numerous potential risk factors to see which were associated with postmenopausal osteoporosis. Women aged 49 or greater presenting for dual-energy x-ray absorptiometry bone scans were recruited from radiology sites in the Hartford, Connecticut, area between January 2007 and March 2009, inclusive. Information was collected regarding primary and secondary risk factors for osteoporosis development, as well as family history and history of pregnancy and breast-feeding. Survey results were subsequently correlated with each woman's dual-energy x-ray absorptiometry scan results. In a sample of 619 women, history of fracture (odds ratio [OR], 12.49), weight less than 127 pounds (OR, 3.50), and use of anticoagulants (OR, 5.40) increased the chance of developing osteoporosis. In contrast, multiparity (OR, 0.45) and history of breast-feeding (OR, 0.38) decreased the development of osteoporosis in postmenopausal women. In women aged 49 to 54, breast-feeding was significantly protective, while low body mass index was most indicative of osteoporosis in women ages 55 to 64. Both previous fracture and low body mass index were associated with osteoporosis in women over age 64. The current results are consistent with other studies suggesting that previous fracture, low body weight, and use of anticoagulants increase the risk of osteoporosis. Our results also suggest that a history of pregnancy and breast-feeding protects against the development of postmenopausal osteoporosis, especially in women aged 49 to 54.

This study aims to evaluate the feasibility of applying high wavenumber (HW) confocal Raman spectroscopy for non-invasive assessment of menopause-related hormonal changes in the cervix as well as for determining the effect of Vagifem(®) treatment on postmenopausal women with atrophic cervix. A rapid HW confocal Raman spectroscopy system coupled with a ball lens fiber-optic Raman probe was utilized for in vivo cervical tissue Raman measurements at 785 nm excitation. A total of 164 in vivo HW Raman spectra (premenopausal (n = 104), postmenopausal-prevagifem (n = 34), postmenopausal-postvagifem (n = 26)) were measured from the normal cervix of 26 patients undergoing colposcopy. We established the biochemical basis of premenopausal, postmenopausal-prevagifem and postmenopausal-postvagifem cervix using semiquantitative biomolecular modeling derived from Raman-active biochemicals (i.e., lipids, proteins and water) that play a critical role in HW Raman spectral changes associated with the menopausal process. The diagnostic algorithms developed based on partial least squares-discriminant analysis (PLS-DA) together with leave-one patient-out, cross-validation yielded the diagnostic sensitivities of 88.5%, 91.2% and 88.5%, and specificities of 91.7%, 90.8% and 99.3%, respectively, for non-invasive in vivo discrimination among premenopausal, postmenopausal-prevagifem and postmenopausal-postvagifem cervix. This work demonstrates for the first time that HW confocal Raman spectroscopy in conjunction with biomolecular modeling can be a powerful diagnostic tool for identifying hormone/menopause-related variations in the native squamous epithelium of normal cervix, as well as for assessing the effect of Vagifem treatment on postmenopausal atrophic cervix in vivo during clinical colposcopic inspections.

Compare the cognitive and motor development in overweight/obese infants versus normal-weight peers and investigate the correlation of body weight, body length and body mass index with cognitive and motor development. We conducted a cross-sectional study with 28 overweight/obese infants and 28 normal-weight peers between 6 and 24 months of age. Both groups were evaluated with cognitive and motor scales of the Bayley-III infant development test. The t-test for independent samples was performed to compare the groups, and the Spearman correlation was used to verify the association between variables. Overweight/obese infants showed lower cognitive and motor composite scores than their normal-weight peers. A significant negative association was found of body weight and body length with cognitive development and of body mass index with motor development. This is the first study that found an effect on both cognitive and motor development in overweight/obese infants when compared with normal-weight peers between 6 and 24 months of age.

This cohort study of 1,614 postmenopausal Japanese women followed for 6.7 years showed that overweight/obesity and underweight are both risk factors for fractures at different sites. Fracture risk assessment may be improved if fracture sites are taken into account and BMI is categorized. The effect of body mass index (BMI) on fracture at a given level of bone mineral density (BMD) is controversial, since varying associations between BMI and fracture sites have been reported. A total of 1,614 postmenopausal Japanese women were followed for 6.7 years in a hospital-based cohort study. Endpoints included incident vertebral, femoral neck, and long-bone fractures. Rate ratios were estimated by Poisson regression models adjusted for age, diabetes mellitus, BMD, prior fracture, back pain, and treatment by estrogen. Over a mean follow-up period of 6.7 years, a total of 254 clinical and 335 morphometric vertebral fractures, 48 femoral neck fractures, and 159 long-bone fractures were observed. Incidence rates of vertebral fracture in underweight and normal weight women were significantly lower than overweight or obese women by 0.45 (95 % confidence interval: 0.32 to 0.63) and 0.61 (0.50 to 0.74), respectively, if BMD and other risk factors were adjusted, and by 0.66 (0.48 to 0.90) and 0.70 (0.58 to 0.84) if only BMD was not adjusted. Incidence rates of femoral neck and long-bone fractures in the underweight group were higher than the overweight/obese group by 2.15 (0.73 to 6.34) and 1.51 (0.82 to 2.77) and were similar between normal weight and overweight/obesity. Overweight/obesity and underweight are both risk factors for fractures at different sites. Fracture risk assessment may be improved if fracture sites are taken into account and BMI is categorized.

We previously reported the secretion of apolipoprotein apoC-I, apoC-II, apoC-III, and apoE from adipose tissue in postmenopausal obese women, suggesting their potential regulation by energy balance in humans. We examined the changes of these apolipoproteins, in relation to changes in cardiometabolic risks, following a hypocaloric diet in overweight/obese women. A total of 137 postmenopausal overweight/obese women who were free of chronic disease were examined at baseline, 56 women of whom were reevaluated following a 6-month hypocaloric diet. At baseline, there was no association between the plasma transferable apolipoproteins with any index of adiposity, insulin sensitivity, lipids, or inflammation, except for apoE with peripheral fat mass (r = 0.18, P hypocaloric diet reduced adiposity, insulin resistance, and inflammatory markers but had no significant effects on plasma transferable apolipoproteins or lipids, whose average concentrations were within normal range at baseline. The changes in total and central, but not peripheral, fat mass associated with changes of apoC-I only (r = 0.28 and r = 0.43; respectively, P < .05). Post-weight-loss apoC-I increased in some women (52%) yet it decreased in others, however there were no differences in cardiometabolic risk factors between the 2 groups. Plasma apoC-I, apoC-II, apoC-III, and apoE are not associated with adiposity, insulin sensitivity, or inflammation in obese but healthy postmenopausal women. Post-weight-loss changes of total and central fat mass associate with changes of apoC-I. Copyright © 2014 National Lipid Association. Published by Elsevier Inc. All rights reserved.

To assess the effect of microablative fractional CO2 laser (MFCO2-Laser) therapy on the vaginal microenvironment of postmenopausal women. Three laser therapies at monthly intervals were applied in postmenopausal women with moderate to severe symptoms of genitourinary syndrome of menopause, pH of vaginal fluid >4.5 and superficial epithelial cells on vaginal smear Vaginal fluid pH values, fresh wet mount microscopy, Gram stain and aerobic and anaerobic cultures were evaluated at baseline and 1 month after each subsequent therapy. Nugent score and Hay-Ison criteria were used to evaluate vaginal flora. Fifty-three women (mean age 57.2 ± 5.4 years) participated and completed this study. MFCO2-Laser therapy increased Lactobacillus (p vaginal pH from a mean of 5.5 ± 0.8 (initial value) to 4.7 ± 0.5 (p aerobic vaginitis or candidiasis did not appear in any participant. MFCO2-Laser therapy is a promising treatment for improving the vaginal health of postmenopausal women by helping repopulate the vagina with normally existing Lactobacillus species and reconstituting the normal flora to premenopausal status.

Although physical activity (PA) is universally recommended, most adults are not regular exercisers. Interactive video dance is a novel form of PA in widespread use among young adults, but interest among adults is not known. Postmenopausal women are an appropriate target for interventions to promote PA because they have an increased risk of health problems related to sedentary behavior. We explored perceived advantages and disadvantages of video dance as a personal exercise option in postmenopausal women. Forty sedentary postmenopausal women (mean age +/- SD 57 +/- 5 years), were oriented in eight small groups to interactive video dance, which uses a force-sensing pad with directional panels: the player steps on the panels in response to arrows scrolling on a screen, synchronized to music. Perceived advantages and disadvantages were elicited through a nominal group technique (NGT) process. Participants generated 113 advantages and 71 disadvantages. The most frequently cited advantages were "it's fun" and "improves coordination" (seven of eight groups), the fact that challenge encourages progress (five of eight groups), the potential for weight loss (four of eight groups), and the flexibility of exercise conditions (three of eight groups). Concerns were the potentially long and frustrating learning process, cost (six of eight groups), and possible technical issues (two of eight groups). The recreational nature of interactive dance exercise was widely appealing to postmenopausal women and might help promote adherence to PA. Initial support to learn basic technical and movement skills may be needed.

In healthy elderly postmenopausal women variations in BMD and BMC at various skeletal sites are associated with differences in weight and lean body mass rather than by variations in habitual physical activity, strength or VO2max.

The objective of this study was an integrated cross-sectional investigation for answering the question whether differences in bone mineral density in elderly postmenopausal women are associated with differences in habitual physical activity and unspecific exercise levels. Two hundred and ninety nine elderly women (69-/+3 years), without diseases or medication affecting bone metabolism were investigated. The influence of weight, body composition and physical activity on BMD was measured at multiple sites using different techniques (DXA, QCT, and QUS). Physical activity and exercise level were assessed by questionnaire, maximum strength of the legs and aerobic capacity. Variations in physical activity or habitual exercise had no effect on bone. The only significant univariate relation between strength/VO(2)max and BMD/BMC that remained after adjusting for confounding variables was between arm BMD (DXA) and hand-grip strength. The most important variable for explaining BMD was weight and for cortical BMC of the femur (QCT) lean body mass. Weight and lean body mass emerge as predominant predictors of BMD in normal elderly women, whereas the isolated effect of habitual physical activity, unspecific exercise participation, and muscle strength on bone parameters is negligible. Thus, an increase in the amount of habitual physical activity will probably have no beneficial impact on bone.

This study investigated whether social modeling of palatable food intake might partially be explained by the direct imitation of a peer reaching for snack food and further, assessed the role of the children's own weight status on their likelihood of imitation during the social interaction. Real-time observations during a 10-min play situation in which 68 participants (27.9% overweight) interacted with normal-weight confederates (instructed peers) were conducted. Children's imitated and non-imitated responses to the confederate's food picking movements were compared using a paired sample t-test. In addition, the pattern of likelihood of imitation was tested using multilevel proportional hazard models in a survival analysis framework. Children were more likely to eat after observing a peer reaching for snack food than without such a cue [t (67) = 5.69, P imitation responses during a social interaction based on their weight status (HR = 2.6, P = 0.03, 95% CI = 1.09-6.20). Overweight children were almost twice as likely to imitate, whereas normal-weight children had a smaller chance to imitate at the end of the interaction. Further, the mean difference in the likelihood of imitation suggest that overweight children might be less likely to imitate in the beginning of the interaction than normal-weight children. The findings provide preliminary evidence that children's imitation food picking movements may partly contribute to social modeling effects on palatable food intake. That is, a peer reaching for food is likely to trigger children's snack intake. However, the influence of others on food intake is a complex process that might be explained by different theoretical perspectives.

To explore if self-perceived overweight in normal weight adolescents influence their weight development into young adulthood and if so, whether physical activity moderates this association. Methods. A longitudinal study of 1196 normal weight adolescents (13–19 yrs who were followed up as young adults (24–30 yrs in the HUNT study. Lifestyle and health issues were assessed employing questionnaires, and standardized anthropometric measurements were taken. Chi square calculations and regression analyses were performed to investigate the associations between self-perceived overweight and change in BMI or waist circumference (WC adjusted for age, age squared, sex, and other relevant cofactors. Results. Adolescents, defined as being normal weight, but who perceived themselves as overweight had a larger weight gain into young adulthood than adolescents who perceived themselves as normal weight (difference in BMI: 0.66 units [CI95%: 0.1, 1.2] and in WC: 3.46 cm [CI95%: 1.8, 5.1]. Level of physical activity was not found to moderate this association. Conclusions. This study reveals that self-perceived overweight during adolescence may affect development of weight from adolescence into young adulthood. This highlights the importance of also focusing on body image in public health interventions against obesity, favouring a “healthy” body weight taking into account natural differences in body shapes.

This study investigated differences in balance and postural skills in normal-weight versus overweight prepubertal boys. Fifty-seven 8-10-year-old boys were categorized overweight (N = 25) or normal-weight (N = 32) according to the International Obesity Task Force cut-off points for overweight in children. The Balance Master, a computerized pressure plate system, was used to objectively measure six balance skills: sit-to-stand, walk, step up/over, tandem walk (walking on a line), unilateral stance and limits of stability. In addition, three standardized field tests were employed: standing on one leg on a balance beam, walking heel-to-toe along the beam and the multiple sit-to-stand test. Overweight boys showed poorer performances on several items assessed on the Balance Master. Overweight boys had slower weight transfer (p test, greater step width while walking (p walking on a line (p test, the unilateral stance and the limits of stability were comparable between both groups. On the balance beam, overweight boys could not hold their balance on one leg as long (p test (p < 0.001) than normal-weight boys. Finally, overweight boys were slower in standing up and sitting down five times in the multiple sit-to-stand task (p < 0.01). This study demonstrates that when categorised by body mass index (BMI) level, overweight prepubertal boys displayed lower capacity on several static and dynamic balance and postural skills.

Partial correlation and regression analyses were used in this study. We showed that there is a linear relationship between bone mineral density and serum uric acid within the normal physiologic range, and higher serum uric acid levels had a protective effect on bone loss in postmenopausal osteoporosis. The significance of the relationship between lumbar bone mineral density ( BMD) and serum uric acid (SUA) levels is unclear. The aims of this study were to investigate on a population-level the association between lumbar BMD and SUA within the normal physiologic range and to determine whether SUA plays a protective role in bone loss in healthy postmenopausal Chinese women. This was a community-based cross-sectional study involving 390 healthy postmenopausal women, 47-89 years of age, conducted in Shenyang, China. The BMD was measured at the lumbar spine using dual-energy X-ray absorptiometry (DXA). The SUA levels were obtained at each DXA visit. Partial correlation and regression analyses were applied to determine the associations. The SUA levels were significantly different between the normal BMD, osteopenia, and osteoporosis groups. The lumbar BMD was positively correlated with SUA in postmenopausal women after adjustment for age (r = 0.212). After adjustment for age, body mass index, systolic blood pressure, diastolic blood pressure, hip circumference, cigarette smoking, alcohol consumption, milk intake, physical exercise, fracture history, total protein, total bilirubin, triglycerides, total cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, serum calcium, and estimated glomerular filtration rate, the lumbar BMD was associated with SUA and the odds ratio of the third SUA quartile was 0.408 (95%CI, 0.198-0.841, P = 0.015), compared to the first quartile of SUA levels. The lumbar BMD was linearly associated with SUA levels within the normal physiologic range of postmenopausal women. Higher SUA levels had a protective effect on bone loss

Exclusively breastfed infants born to obese mothers have previously been shown to gain less weight by 1-month postpartum than infants of normal-weight mothers. Our hypothesis is that human milk composition and volume may differ between obese and normal-weight mothers. To compare human milk leptin, macronutrient concentration, and volume in obese and normal-weight mothers. Mother and infant characteristics were studied as secondary aims. This cross-sectional observational study compared 50 obese mothers matched for age, parity, ethnic origin, and educational level with 50 normal-weight mothers. Leptin, macronutrient human milk concentration, and milk volume were determined at 1 month in exclusively breastfed infants. Mother characteristics and infant growth were recorded. Human milk leptin concentration was higher in obese mothers than normal-weight mothers (4.8±2.7 vs. 2.5±1.5 ng.mL-1, pobese and normal-weight mothers in protein, lipid, carbohydrate content, and volume, nor in infant weight gain. Leptin concentration was higher in the milk of obese mothers than that of normal-weight mothers, but macronutrient concentration was not. It remains to be established whether the higher leptin content impacts on infant growth beyond the 1-month of the study period.

Full Text Available The purpose of this study was to determine if differences in oxygen uptake kinetics and oxygen deficit existed between normal weight and severely overweight adolescent girls. Subjects included 10 normal weight and 8 severely overweight girls. The participants performed a leg cycling VO2 peak test and a constant load leg cycling test at 80% of the ventilatory threshold (T-vent. In the constant workload test O2 kinetics as indicated by Phase I (VO2 L at 20 sec and Phase II time constants (t were determined. Also, the O2 deficit (VO2 L was measured. As expected significant differences were noted in body composition and VO2 peak relative to mass with normal weight body mass averaging 55.3 ± 7.0 kg, severely overweight 90.5 ± 18.0 kg, % fat normal weight 27.3 ± 3.9%, severely overweight 49.7 ± 4.9% and VO2 peak (ml·kg-1·min-1 normal weight 32.0 ± 2.7 and severely overweight 22.0 ± 5.3. VO2 peak (l·min-1 and T-vent (%VO2 max were similar between groups. Results revealed similar O2 kinetic responses between groups; phase I kinetics normal weight 0.72 ± 0.15 L; severely overweight 0.75 ± 0.13L, phase II (t normal weight 41.5 ± 21.3 sec; severely overweight 33.9 ± 22.7 sec. However, the O2 deficit was significantly higher in the severely overweight (0.75 ± 0.15L when compared to the normal weight group (0.34 ± 0.13L. Correlations ranged from r = -0.15 to 0.51 between VO2 peak (L·min-1 or fat weight and phase I, t and O2 deficit. These data generally support previous research concerning the independence of O2 uptake response and body size

2,3-Diphosphoglycerate levels were assayed in 154 pregnant women in third trimester (61 normal, 52 diabetic, 19 with gestational hypertension, 7 with fetal macrosomia, and 15 with idiopathic fetal underdevelopment). A correlation was found between 2,3-diphosphoglycerate levels and birth weight (absolute and relative birth weight or birth weight expressed as percentile), which was negative in normal patients evaluated in the last 7 days before delivery (r = 0.38; p = 0.04) and positive in diabetic patients (evaluated in the third trimester and in the last 7 days before delivery) and in patients with gestational hypertension (evaluated in the third trimester) (r and p values differ according to whether birth weight is expressed as absolute, relative, or a percentile). No correlation was found between 2,3-diphosphoglycerate levels and birth weight in patients with neonatal underdevelopment or macrosomia of unknown origin. On the basis of these results we hypothesize that in some conditions the fetus can influence maternal 2,3-diphosphoglycerate levels and hence its own oxygen supply and growth in utero.

The present study was conducted to compare serum leptin and insulin resistance levels between Korean postmenopausal long-term semi-vegetarians and non-vegetarians. Subjects of this study belonged to either a group of postmenopausal vegetarian women (n = 54), who maintained a semi-vegetarian diet for over 20 years or a group of non-vegetarian controls. Anthropometric characteristics, serum leptin, serum glucose, serum insulin, insulin resistance (HOMA-IR; Homeostasis Model Assessment of Insulin Resistance), and nutrient intake were compared between the two groups. The vegetarians showed significantly lower body weight (p vegetarians. The HOMA-IR of the vegetarians was significantly lower than that of the non-vegetarians (p vegetarian diet might be related to lower insulin resistance independent of the % of body fat in postmenopausal women.

Anorexia nervosa and normal-weight hypothalamic amenorrhea are characterized by hypogonadism and hypercortisolemia. However, it is not known whether these endocrine abnormalities result in reductions in adrenal and/ or ovarian androgens or androgen precursors in such women, nor is it known whether relative androgen deficiency contributes to abnormalities in bone density and body composition in this population. Our objective was to determine whether endogenous androgen and dehydroepiandrosterone sulfate (DHEAS) levels: 1) are reduced in women with anorexia nervosa and normal-weight hypothalamic amenorrhea, 2) are reduced further by oral contraceptives in women with anorexia nervosa, and 3) are predictors of weight, body composition, or bone density in such women. We conducted a cross-sectional study at a general clinical research center. A total of 217 women were studied: 137 women with anorexia nervosa not receiving oral contraceptives, 32 women with anorexia nervosa receiving oral contraceptives, 21 normal-weight women with hypothalamic amenorrhea, and 27 healthy eumenorrheic controls. Testosterone, free testosterone, DHEAS, bone density, fat-free mass, and fat mass were assessed. Endogenous total and free testosterone, but not DHEAS, were lower in women with anorexia nervosa than in controls. More marked reductions in both free testosterone and DHEAS were observed in women with anorexia nervosa receiving oral contraceptives. In contrast, normal-weight women with hypothalamic amenorrhea had normal androgen and DHEAS levels. Lower free testosterone, total testosterone, and DHEAS levels predicted lower bone density at most skeletal sites measured, and free testosterone was positively associated with fat-free mass. Androgen levels are low, appear to be even further reduced by oral contraceptive use, and are predictors of bone density and fat-free mass in women with anorexia nervosa. Interventional studies are needed to confirm these findings and determine whether

Postmenopausal pregnancy? Evaluation of elevated hCG in a 59-year-old woman.

Slightly elevated serum human chorionic gonadotropin (hCG) can be a normal finding in postmenopausal women. We report a case of a 59-year-old woman with a history of abnormal uterine bleeding who presented with a concern for pregnancy after developing nausea and vomiting a few weeks after unprotected intercourse. Although pregnancy was extremely unlikely, hCG was obtained in order to reassure the patient since she reported that her mother conceived at the age of 60. Serum hCG was positive, prompting concern for malignancy versus pregnancy. Stable serum hCG levels, elevated follicle-stimulating hormone and negative transvaginal ultrasound ruled out both malignancy and pregnancy. Positive serum pregnancy test and hCG elevation was attributed to normal postmenopausal state. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Myking, O.; Kjoesen, B.; Bassoee, H.H.

1980-01-01

The influence of pooled serum from either obese or normal weight males on glucose metabolism in human leucocytes has been studied. Leucocytes from normal weight males were incubated with 10-90% pooled serum and either [U- 14 C], or [1- 14 C]glucose. Compared to serum from the normal weight males, serum from the obese group had a more stimulating effect on the 14 CO 2 and [ 14 C]lactate production from [U- 14 C]glucose and on the 14 CO 2 production from [1- 14 C]glucose. The two serum pools had the same stimulating effect on the Embden-Meyerhof pathway as indicated by the formation of [ 14 C]lactate from [l- 14 C]glucose. Calculations revealed that the activity in the pentose phosphate pathway was stimulated more by serum from obese, than from normal weight males. It is a possibility that increased stimulation of the pentose phosphate pathway may contribute to the development of overweight. (author)

Eating frequency has been negatively related to body mass index (BMI). The relationship between eating frequency and weight loss maintenance is unknown. This secondary analysis examined eating frequency (self-reported meals and snacks consumed per day) in weight loss maintainers (WLM) who had reduced from overweight/obese to normal weight, normal weight (NW) individuals, and overweight (OW) individuals. Data collected July 2006 to March 2007 in Providence, RI, included three 24-hour dietary recalls (2 weekdays, 1 weekend day) analyzed using Nutrient Data System for Research software from 257 adults (WLM n=96, 83.3% women aged 50.0±11.8 years with BMI 22.1±1.7; NW n=80, 95.0% women aged 46.1±11.5 years with BMI 21.1±1.4; OW n=81, 53.1% women aged 51.4±9.0 years with BMI 34.2±4.1) with plausible intakes. Participant-defined meals and snacks were ≥50 kcal and separated by more than 1 hour. Self-reported physical activity was highest in WLM followed by NW, and then OW (3,097±2,572 kcal/week, 2,062±1,286 kcal/week, and 785±901 kcal/week, respectively; Pmeals consumed (2.7±0.4 meals/day). Eating frequency, particularly in regard to a pattern of three meals and two snacks per day, may be important in weight loss maintenance. Copyright © 2011 American Dietetic Association.

This study aimed to compare moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA) in normal-weight and overweight boys and girls during school recess. Four hundred twenty children, age 6 to 10 years, were randomly selected from 25 schools in England. Three hundred seventy-seven children completed the study. BMI was calculated from height and weight measurements, and heart rate reserve thresholds of 50% and 75% reflected children's engagement in MVPA and VPA, respectively. There was a significant main effect for sex and a significant interaction between BMI category and sex for the percent of recess time spent in MVPA and VPA. Normal-weight girls were the least active group, compared with overweight boys and girls who were equally active. Fifty-one boys and 24 girls of normal weight achieved the 40% threshold; of these, 30 boys and 10 girls exceeded 50% of recess time in MVPA. Eighteen overweight boys and 22 overweight girls exceeded the 40% threshold, whereas 8 boys and 8 girls exceeded the 50% threshold. Overweight boys were significantly less active than their normal-weight male counterparts; this difference did not hold true for girls. Even though nearly double the number of normal-weight children achieved the 40% of MVPA during recess compared with overweight children, physical activity promotion in school playgrounds needs to be targeted not only at overweight but at other health parameters, as 40 overweight children met the 40% MVPA target proposed for recess.

To examine behavioral and body size influences on the underreporting of energy intake by obese and normal-weight women. Seven-day estimated food records were kept by subjects before they participated in a 49-day residential study. Self-reported energy intake was compared with energy intake required to maintain a stable body weight during the residential study (reference standard). Energy intake bias and its relationship to various body size and behavioral measures were examined. Twenty-two, healthy, normal-weight (mean body mass index [BMI] = 21.3) and obese (mean BMI = 34.2) women aged 22 to 42 years were studied. Analysis of variance, paired t test, simple linear regression, and Pearson correlation analyses were conducted. Mean energy intake from self-reported food records was underreported by normal-weight (-9.7%) and obese (-19.4%) women. BMI correlated inversely with the energy intake difference for normal-weight women (r = -.67, P = .02), whereas the Beck Depression Inventory correlated positively with the energy intake difference for obese women (r = .73, P behavioral traits play a role in the ability of women to accurately self-report energy intake. BMI appears to be predictive of underreporting of energy intake by normal-weight women, whereas emotional factors related to depression appear to be more determinant of underreporting for obese women. Understanding causative factors of the underreporting phenomenon will help practicing dietitians to devise appropriate and realistic diet intervention plans that clients can follow to achieve meaningful change.

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

Learning weighted sparse representation of encoded facial normal information for expression-robust 3D face recognition

KAUST Repository

Li, Huibin

2011-10-01

This paper proposes a novel approach for 3D face recognition by learning weighted sparse representation of encoded facial normal information. To comprehensively describe 3D facial surface, three components, in X, Y, and Z-plane respectively, of normal vector are encoded locally to their corresponding normal pattern histograms. They are finally fed to a sparse representation classifier enhanced by learning based spatial weights. Experimental results achieved on the FRGC v2.0 database prove that the proposed encoded normal information is much more discriminative than original normal information. Moreover, the patch based weights learned using the FRGC v1.0 and Bosphorus datasets also demonstrate the importance of each facial physical component for 3D face recognition. © 2011 IEEE.

• BACKGROUND: There are few epidemiologic studies on vitamin D status of postmenopausal women in the Middle East countries. This study aimed to investigate the 25-hydroxyvitamin D levels in  ostmenopausal women living in the north-west of Iran.
• METHODS: Using the records of the local household registry, 300 cases were enrolled by simple random sampling. Serum 25-hydroxyvitamin D levels were determined by fully automated chemiluminescent  mmunoassay. In addition, the study included survey questions regarding age, body weight and height, use of supplements and skin protection agents and clinical and reproductive histories.
• RESULT: Our cases had the mean age of 63.41 ± 4.64 years with menopause duration of 16.79 ± 6.15 years. Median and interquartile 25-75 range of vitamin D were 14.20 ng/ml and 7-37.2 ng/ml  espectively. We found hypovitaminosis D [25(OH D < 10 ng/ml] in 38.3% of our cases. Serum 25(OH D concentrations were not  ignificantly correlated with age or BMI.
• CONCLUSION: These findings indicate that 25(OH D levels in postmenopausal women of north-west Iran are low. Studies to elucidate and assess the dietary intake of vitamin D in elderly women of this region can be of further benefit.

To examine the association between observer ratings of physical attractiveness and weight preoccupation for female adolescents, and to explore any ethnic differences between Caucasian, African-American, and Hispanic females. Normal-weight female adolescents who had participated in the National Longitudinal Study of Adolescent Health in-home Wave II survey were included (n = 4,324). Physical attractiveness ratings were made in vivo by interviewers. Using logistic regression models stratified by ethnicity, the associations between observer-rated attractiveness and weight preoccupation were examined after controlling for demographics, measured body mass index (BMI) and psychosocial factors. Caucasian female adolescents perceived as being more attractive reported significantly greater weight preoccupation compared with those rated as being less attractive. Observed attractiveness did not relate to weight preoccupation among African-American or Hispanic youth when controlling for other factors. For Caucasian female adolescents, being perceived by others as more attractive may be a risk factor for disordered eating.

Despite considerable health risks due to lower levels of estrogen production and the compounding antiestrogenic effects of nicotine, postmenopausal females continue to smoke. These females face significant barriers to cessation, including negative affect, weight concerns, and menopausal symptom severity. The current pilot study explored the effect of negative affect, weight concerns, and menopausal symptom severity on motivation and readiness to quit smoking. Eighteen postmenopausal smokers were randomized to receive brief motivational interviewing (B-MI; n = 8) or control treatment (i.e., a 1-hour video, n = 10). Participants completed measures of negative affect, weight concerns, and menopausal symptoms, as well as measures of motivation and readiness to quit. Motivation and readiness to quit were reassessed one week following treatment. At baseline, weight concerns, specifically surrounding smoking to prevent overeating, were identified as related to increased motivation to quit smoking. Menopausal symptom severity, specifically somatic symptoms, assessed at baseline, was associated with increased readiness for cessation. B-MI did not increase motivation or readiness to quit; however, results indicate that cigarettes per day decreased from baseline to follow-up by approximately 20-30%. These results provide valuable insight into enhancing engagement in a cessation treatment among this population. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Polycystic ovary syndrome (PCOS) and obesity are associated with diabetes and cardiovascular disease, but it is unclear to what extent PCOS contributes independently of obesity. The objective of the study was to investigate whether insulin sensitivity and insulin's effects on the microcirculation are impaired in normal-weight and obese women with PCOS. Thirty-five women with PCOS (19 normal weight and 16 obese) and 27 age- and body mass index-matched controls (14 normal weight and 13 obese) were included. Metabolic Insulin sensitivity (isoglycemic-hyperinsulinemic clamp) and microvascular insulin sensitivity [endothelium dependent (acetylcholine [ACh])] and endothelium-independent [sodium nitroprusside (SNP)] vasodilation with laser Doppler flowmetry was assessed at baseline and during hyperinsulinemia. Metabolic insulin sensitivity (M/I value) and the area under the response curves to ACh and SNP curves were measured to assess microcirculatory function at baseline and during insulin infusion (microvascular insulin sensitivity). Obese women were more insulin resistant than normal-weight women (P PCOS women were more resistant than obese controls (P = 0.02). In contrast, normal-weight women with PCOS had similar insulin sensitivity, compared with normal-weight women without PCOS. Baseline responses to ACh showed no difference in the four groups. ACh responses during insulin infusion were significantly greater in normal-weight PCOS and controls than in obese PCOS and controls. PCOS per se had no significant influence on ACh responses during insulin infusion. During hyperinsulinemia, SNP-dependent vasodilatation did not significantly increase, compared with baseline in the four groups. PCOS per se was not associated with impaired metabolic insulin sensitivity in normal-weight women but aggravates impairment of metabolic insulin sensitivity in obese women. In obese but not normal-weight women, microvascular and metabolic insulin sensitivity are decreased, independent

Relation between Protein Intrinsic Normal Mode Weights and Pre-Existing Conformer Populations.

Intrinsic fluctuations of a protein enable it to sample a large repertoire of conformers including the open and closed forms. These distinct forms of the protein called conformational substates pre-exist together in equilibrium as an ensemble independent from its ligands. The role of ligand might be simply to alter the equilibrium toward the most appropriate form for binding. Normal mode analysis is proved to be useful in identifying the directions of conformational changes between substates. In this study, we demonstrate that the ratios of normalized weights of a few normal modes driving the protein between its substates can give insights about the ratios of kinetic conversion rates of the substates, although a direct relation between the eigenvalues and kinetic conversion rates or populations of each substate could not be observed. The correlation between the normalized mode weight ratios and the kinetic rate ratios is around 83% on a set of 11 non-enzyme proteins and around 59% on a set of 17 enzymes. The results are suggestive that mode motions carry intrinsic relations with thermodynamics and kinetics of the proteins.

Early anthropometric and metabolic changes during a caloric-restricted diet in obese postmenopausal women and correlations between these factors with activity in brain areas involved in processing of visual food related stimuli were investigated. An 8-week prospective intervention study of 18 healthy postmenopausal women, with a body mass index of 30-35 kg m -2 . The first 2 weeks subjects were on an isocaloric diet and 4 weeks on a 1000 kcal restricted diet followed by 2 weeks on an isocaloric diet. Anthropometric and laboratory analyses were performed weekly during the isocaloric diet and three times a week during the caloric-restricted diet. Functional magnetic resonance imaging scans were obtained before and after the caloric restriction in four separate sessions (fasting or sated). Generalized Estimating Equations analysis was used for data analysis. A mean weight loss of 4.2±0.5 kg (4.8%) and a 4.2±0.4 cm decline in waist circumference were achieved. In the first week of caloric restriction, triglyceride, leptin, resistin and adiponectin levels as well as systolic blood pressure decreased and insulin-like growth factor-binding protein 1 levels increased. During and after weight loss, a significant increase in ghrelin levels was observed. Before weight loss, increased activation of the right amygdala was seen in response to food stimuli, and free fatty acids and glucose correlated with activity in various areas involved in food reward processing. After weight loss, fasting ghrelin and sated leptin levels correlated with activity in these areas. Already in the first week of caloric restriction in obese postmenopausal women, various favourable metabolic changes occur before clinically relevant weight loss is achieved. Activity in the amygdala region and correlations of metabolic factors with activity in brain areas involved in food reward processing differ substantially before and after weight loss.

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

Regional and total bone mass were determined in three groups of women by photon absorptiometry of the distal radius [bone mineral content (BMC)] and total neutron activation analysis [total body calcium (TBCa)], respectively. There were three groups of patients: group A, osteoporotic women treated with a variety of pharmacologic agents; group B, osteoporotic women (controls) taking only calcium supplements; and group C, normal postmenopausal women. The mean TBCa and BMC were considerably higher in the postmenopausal women than in the osteoporotic women. The rate of change of bone mass in group C was -0.45%/yr and -0.9%/yr for the total skeleton and radius, respectively. Group B had no significant rate of loss, whereas group A demonstrated a significant increase in TBCa of 0.75%/yr with no change in the BMC of the radius. There were no significant between-subject correlations for the slopes (rates of change) of the two bone mineral measurements

To investigate relationships between body fat and its distribution and carbohydrate and lipid tolerance using statistical comparisons in post-menopausal women. Sequential meal, postprandial study (600 min) which included a mixed standard breakfast (30 g fat) and lunch (44 g fat) given at 0 and 270 min, respectively, after an overnight fast. Twenty-eight post-menopausal women with a diverse range of body weight (body mass index (BMI), mean 27.2, range 20.5-38.8 kg/m2) and abdominal fat deposition (waist, mean 86.4, range 63.5-124.0 cm). Women with BMI 37 kg/m2, age > 80 y and taking hormone replacement therapy (HRT) were excluded. Anthropometric measurements were performed to assess total and regional fat deposits. The concentrations of plasma total cholesterol, high density lipoprotein (HDL) cholesterol, triacylglycerol (TAG), glucose, insulin (ins), non-esterified fatty acids (NEFA) and apolipoprotein (apo) B-48 were analysed in plasma collected at baseline (fasted state) and at 13 postprandial time points for a 600 min period. Insulin concentrations in the fasted and fed state were significantly correlated with all measures of adiposity (BMI, waist, waist-hip ratio (W/H), waist-height ratio (W/Ht) and sum of skinfold thickness (SSk)). After controlling for BMI, waist remained significantly and positively associated with fasted insulin (r=0.559) with waist contributing 53% to the variability after multiple regression analysis. After controlling for waist, BMI remained significantly correlated with postprandial (IAUC) insulin (r=0.535) contributing 66% of the variability of this measurement. No association was found between any measures of adiposity and glucose concentrations, although insulin concentration in relation to glucose concentration (glucose-insulin ratio) was significantly negatively correlated with all measures of adiposity. A significant positive correlation was found between fasted TAG and BMI (r=0.416), waist (r=0.393) and Ssk (r=0.457) and

We investigated changes in cardiorespiratory performance, BMI and leisure-time physical activity among Finnish adolescents from 2003 to 2010. In addition, we compared cardiorespiratory performance levels between normal weight and overweight adolescents, grouped according to their physical activity. Participants were a national representative samples of 15-16-year-old adolescents in their final (ninth) year of comprehensive school in 2003 (n = 2258) and in 2010 (n = 1301). They performed an endurance shuttle run test and reported their height and weight and leisure time physical activity on a questionnaire. Results showed no significant secular changes in cardiorespiratory performance from 2003 to 2010. The mean BMI increased in boys. Leisure-time physical activity increased among normal weight girls. Adolescents of normal weight had better cardiorespiratory performance than those classified as overweight at both assessment points. BMI-adjusted physical activity was a significant determinant for cardiorespiratory performance among overweight adolescents, and very active overweight adolescents had similar cardiorespiratory performance levels as moderately active adolescents of normal weight. The results of the present study support the idea that the physical activity has the great importance for the cardiorespiratory performance in adolescents. Overweight adolescents, in particular, benefit from higher levels of physical activity.

To document the prevalence of non-alcoholic fatty liver disease (NAFLD) and metabolic parameters among normal-weight and overweight schoolchildren. Cross-sectional study. Thirteen private schools in urban Faridabad, Haryana. 961 school children aged 5-10 years. Ultrasound testing was done, and 215 with fatty liver on ultrasound underwent further clinical, biochemical and virological testing. Prevalence of fatty liver on ultrasound, and NAFLD and its association with biochemical abnormalities and demographic risk factors. On ultrasound, 215 (22.4%) children had fatty liver; 18.9% in normal-weight and 45.6% in overweight category. Presence and severity of fatty liver disease increased with body mass index (BMI) and age. Among the children with NAFLD, elevated SGOT and SGPT was observed in 21.5% and 10.4% children, respectively. Liver enzyme derangement was significantly higher in overweight children (27% vs 19.4% in normal-weight) and severity of fatty liver (28% vs 20% in mild fatty liver cases). Eleven (8.1%) children with NAFLD had metabolic syndrome. Higher BMI (OR 35.9), severe fatty liver disease (OR 1.7) and female sex (OR 1.9) had strong association with metabolic syndrome. 22.4% of normal-weight and overweight children aged 5-10 years had fatty liver. A high proportion (18.9%) of normal-weight children with fatty liver on ultrasound indicates the silent burden in the population.

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.

We aimed to characterize metabolic status by body mass index (BMI) status. The CRONICAS longitudinal study was performed in an age-and-sex stratified random sample of participants aged 35 years or older in four Peruvian settings: Lima (Peru's capital, costal urban, highly urbanized), urban and rural Puno (both high-altitude), and Tumbes (costal semirural). Data from the baseline study, conducted in 2010, was used. Individuals were classified by BMI as normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30 kg/m2), and as metabolically healthy (0-1 metabolic abnormality) or metabolically unhealthy (≥2 abnormalities). Abnormalities included individual components of the metabolic syndrome, high-sensitivity C-reactive protein, and insulin resistance. A total of 3088 (age 55.6±12.6 years, 51.3% females) had all measurements. Of these, 890 (28.8%), 1361 (44.1%) and 837 (27.1%) were normal weight, overweight and obese, respectively. Overall, 19.0% of normal weight in contrast to 54.9% of overweight and 77.7% of obese individuals had ≥3 risk factors (poverweight and 3.9% of obese individuals were metabolically healthy and, compared to Lima, the rural and urban sites in Puno were more likely to have a metabolically healthier profile. Most Peruvians with overweight and obesity have additional risk factors for cardiovascular disease, as well as a majority of those with a healthy weight. Prevention programs aimed at individuals with a normal BMI, and those who are overweight and obese, are urgently needed, such as screening for elevated fasting cholesterol and glucose.

Full Text Available Abstract Background Although lifestyle interventions targeting multiple lifestyle behaviors are more effective in preventing unhealthy weight gain and chronic diseases than intervening on a single behavior, few studies have compared individual and combined effects of diet and/or exercise interventions on health-related quality of life (HRQOL. In addition, the mechanisms of how these lifestyle interventions affect HRQOL are unknown. The primary aim of this study was to examine the individual and combined effects of dietary weight loss and/or exercise interventions on HRQOL and psychosocial factors (depression, anxiety, stress, social support. The secondary aim was to investigate predictors of changes in HRQOL. Methods This study was a randomized controlled trial. Overweight/obese postmenopausal women were randomly assigned to 12 months of dietary weight loss (n = 118, moderate-to-vigorous aerobic exercise (225 minutes/week, n = 117, combined diet and exercise (n = 117, or control (n = 87.

Full Text Available Background Menopausal symptoms in postmenopausal women tend to decrease health-related quality of life (HRQoL. The present study’s objective was to determine the effect of daily supplementation of 100 mg soy isoflavones on menopausal symptoms of healthy postmenopausal women. Isoflavones are phytoestrogens abundantly found in soy beans, and several studies have demonstrated that isoflavones are the best among the phytoestrogens. Methods The study was a community-based double blind randomized controlled trial involving 60 healthy postmenopausal women, aged between 48–60 years, in the Mampang Prapatan District, South Jakarta. Participants were block-randomized to receive either 100 mg soy-isoflavone + 500 mg calcium carbonate (intervention group or 500 mg calcium carbonate only (control group. Both supplements were taken daily for 12 weeks, from January to April 2010. Menopausal symptoms (measured by Menopause Rating Scale questionnaire were assessed at baseline and after supplementation. Chi-square test was used to examine the effect of soy isoflavone supplementation on menopausal symptoms. Results Fifty-six (93.3% of participants completed the study. There were no statistically significant differences (p>0.05 in the prevalence of menopausal symptoms between the isoflavone group and the control group. However, supplementation of soy isoflavones for 12 weeks tended to decrease the prevalence of menopausal symptoms in women with normal body mass index and adequate daily dietary isoflavone intake. Conclusion Daily supplementation of 100 mg soy isoflavones for 12 weeks tend to decrease the incidence of menopausal symptoms in postmenopausal women.

The aim of this study was to investigate the possible risk factors related with osteoporosis in women with spontaneous menopause. Five hundred and one postmenopausal women were divided into three groups as normal, osteopenic and osteoporotic according to their bone mineral density (BMD). By face-to-face interview, parity, age at menarche, age at menopause, duration of fertility, duration of menopause, first pregnancy age, total lactation period, exercise, smoking were assessed. Women with menopause age before 40 years, surgical menopause, who had any anti-osteoporosis treatment, hormone replacement therapy at the time of BMD measurement and corticosteroid use longer than 6 months were excluded from the study. Among 501 postmenopausal women, 107 women were classified as normal, 170 as osteopenic and 224 as osteoporotic. Among demographic features of patients, there was statistically significant difference between the groups in age, BMI and parity (p osteoporosis (OR 0.42, CI 95 % 0.27-0.66; OR 0.36, CI 95 % 0.24-0.56, respectively), but age was positively correlated with osteoporosis (OR 1.13, CI 95 % 1.01-1.17) CONCLUSIONS: Duration of fertility (years of menstruation) longer than 33 years and body mass index higher than 32 seem to protect against postmenopausal osteoporosis. Age is also an independent risk factor for postmenopausal osteoporosis.

Weight preoccupations have been frequently reported in normal-weight subjects. Subthreshold anorexia nervosa (s-AN, all DSM IV TR criteria except amenorrhea or underweight) is a form of eating disorder not otherwise specified that has received scarce scientific attention. Under a case-control design we compared the general characteristics, body composition, and psychopathological features of normal-weight patients with s-AN with those of BMI- and sex-matched controls. Participants in this pilot study included 9 normal-weight women who met the DSM IV TR criteria for s-AN and 18 BMI-matched normal-weight controls. The general characteristics of the study participants were collected by questionnaire. Body composition was measured by bioelectrical impedance. Behavioral and psychological measures included the standardized symptom checklist (SCL-90-R) and the eating disorder inventory (EDI-2). There were no differences in age, education, employment status, marital status, and history of previous slimming treatment in the two study groups. In addition, anthropometric measures and body composition of s-AN patients and BMI-matched normal weight controls were not significantly different. In the s-AN subgroup, we found a significant relationship between waist circumference and the SCL-90-R obsessivity-compulsivity scale (n=9, r=-0.69, pstudy cohort. These pilot results suggest that psychopathological criteria (particularly related to the obsessivity-compulsivity dimension) may be more useful than anthropometric measures for screening of s-AN in normal-weight women.

Full Text Available Background: Body dissatisfaction has been identified as a psychological correlate of obesity that is related to disordered eating, poor self-esteem, and depression. However, not all individuals with obesity are equally vulnerable to these correlates, and ‘normative discontent' is present in individuals with normal weight, too. In this light, the complex relationship of body image and individual weight status seems like a worthwhile direction of research inquiry. As such, this review aims to systematically explore the degree of body dissatisfaction in individuals with obesity compared to normal-weight individuals. Methods: A systematic literature search was conducted. All quantitative studies of adult samples reporting results regarding differences in body dissatisfaction between individuals with normal weight and obesity were included. Results: 17 articles were found. Across studies, individuals with obesity reported higher body dissatisfaction than normal-weight individuals (questionnaires: d = 0.89, 95% CI = 0.63-1.16, p Conclusion: The findings underline the severity of body dissatisfaction among individuals with obesity and especially among women. Future research recommendations are discussed.

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

Full Text Available Context: Nutrition plays a vital role in the quality of life in postmenopausal women. Aim: The aim is to determine the dietary intake, physical activity, and assess the body mass index (BMI among postmenopausal women. Settings and Design: A community-based sample survey. Materials and Methods: The present study included 140 postmenopausal women (40–70 years from Udupi, Manipal areas of Karnataka. The study was carried out between July and December 2013. Sociodemographic data were collected using a questionnaire. Anthropometric data included height, weight, waist, and hip circumference. Dietary intake was determined using 24 h dietary recall. Physical activity information was collected. Statistical Analysis Used: Data were analyzed using SPSS version 16 software. Paired t-test was performed to determine the dietary adequacy. Results: Obesity was 42.1% among the study participants. Increased WHR and waist circumference were 82.1% and 77.1%. Mean daily intake of calcium and saturated fatty acids were significantly higher than recommended dietary allowance (RDA (P < 0.001. Mean intake of energy, protein, carbohydrate, mono and poly unsaturated fatty acid, fiber and sodium were significantly lower than RDA (P < 0.001. Average daily intake of cereals, pulses, roots and tubers, meat and products, fats and oils, green leafy, and other vegetables were significantly (P < 0.001 lower than RDA. Intake of fruits, milk and milk products, and sugar was significantly higher (P < 0.001 than RDA. Only 37.1% of women performed moderate or active exercises regularly. Conclusions: Even though, nutrient and food group deficiencies were observed among postmenopausal women physical inactivity and effects of menopausal transition instigate increased BMI imposing a need to educate on nutrition and physical activity.

Various questions arise in the application of ICRP ''Standard Man'' values to Japanese. One of the questions is that ''Standard Man'' values of the thyroid are different from normal Japanese values. A systematic survey of past reports was carried out with a view to search for normal Japanese values of the thyroid. The subjects of search were weight, iodine content and iodine uptake rate (f sub(w)) of the thyroid. These are important factors in the estimation of the radiation dose of the thyroid caused by internal contamination of radioiodine, and are foreseen to have the difference between Japanese and ''Standard Man''. The result of study suggested that the weight of the thyroid of normal Japanese is about 19 g for adult male and about 17 g for adult female, and that the iodine content is 12-22 mg and iodine uptake rate (f sub(w)) is about 0.2.

The high-resolution ultrasound has taken to discover small ovary cysts in postmenopausal asymptomatic women who in another situation would not been detected; these cysts frequently disappear spontaneously and rarely develop cancer; however, they are treated aggressively. To know the prevalence, evolution and treatment of ovary simple cysts in the postmenopausal women in our department, since in our country there are not studies that had analyzed these data. We made a retrospective and descriptive study in the Service of Biology of the Human Reproduction of the Hospital Juarez de Mexico, in a four-year period (2000-2003) that included 1,010 postmenopausal women. The statistical analysis was made using the SPSS software program with which we obtained descriptive measurements in localization, dispersion and by a graphic analysis. We found a simple cysts prevalence of 8.2% (n = 83); the average of age at the diagnosis time was 50.76 years with a standard deviation of 5.55; the cysts diameter was between 0.614 to 12,883 cm with a mean and standard deviation of 2.542 and 1.91 cm respectively; in 27.71% of the cases (n = 23), the cysts disappear spontaneously in the follow up of 3 to 36 month (mean of 14.1). Surgery was indicated in 16.46% (n = 13), by increase in the size of the cyst in 9 patients (11.64%) and by changes in morphology from simple to complex in 4 (4.82%). Tumor like markers were made only to 37 patients (44.57%), which were in normal ranks; no carcinoma was found in this group. The prevalence of ovary simple cysts was similar to the reported in literature. Risk of cancer of these cysts is extremely low when a suitable evaluation is made, a reason why the conservative treatment is suggested when these are simple cysts lesser than 5cm with Ca-125 levels within normal ranks. We recommend a follow up every 3-6 months by Doppler color ultrasound and tumor like markers for five years.

To compare the effects of a caloric restriction (CR) on body composition, lipid profile, and glucose homeostasis in obese postmenopausal women with and without metabolic syndrome (MetS). Secondary analyses were performed on 73 inactive obese postmenopausal women (age 57.7 ± 4.8 years; body mass index 32.4 ± 4.6 kg/m) who participated in the 6-month CR arm of a study of the Montreal-Ottawa New Emerging Team. The harmonized MetS definition was used to categorize participants with MetS (n = 20, 27.39%) and without MetS (n = 53, 72.61%). Variables of interest were: body composition (dual-energy X-ray absorptiometry), body fat distribution (computed tomography scan), glucose homeostasis at fasting state and during a euglycemic/hyperinsulinemic clamp, fasting lipids, and resting blood pressure. By design, the MetS group had a worse cardiometabolic profile, whereas both groups were comparable for age. Fifty-five participants out of 73 displayed no change in MetS status after the intervention. Twelve participants out of 20 (or 60.0%) in the MetS group had no more MetS after weight loss (P = NS), whereas 6 participants out of 53 (or 11.3%) in the other group developed the MetS after the intervention (P = NS). Overall, indices of body composition and body fat distribution improved significantly and similarly in both groups (P between 0.03 and 0.0001). Furthermore, with the exception of triglyceride levels and triglycerides/high-density lipoprotein cholesterol ratio, which decrease significantly more in the MetS group (P ≤ 0.05), no difference was observed between groups for the other variables of the cardiometabolic profile. Despite no overall significant effects on MetS, heteregeneous results were obtained in response to weight loss in the present study, with some improving the MetS, whereas other displaying deteriorations. Further studies are needed to identify factors and phenotypes associated with positive and negative cardiometabolic

Objective: To explore the clinical value of determination of serum PRL levels inpost-menopausal women. Methods: Serum PRL levels were determined with RIA in 596 post-menopausal women (age 45-59, mean 55). Results: The normal range of serum PRL level in this laboratory was 0-30 ng/ml. Among the 596 women tested, 77(13%) had their PRL levels above 30 ng/ml. Further investigation with CT and/or MRI revealed presence of micro-pituitary-adenoma in 31 of the Symptoms of menopausal syndrome and osteoporosis were much more severe in women with hyperprolactinemia then in those without. Conclusion: As hyperprolactinemia might be a high risk factor for development of breast cancer, hormone replacement therapy (HRT) in menopausal women with hyperprolactinemia should be applied very cautiously, even withheld at all. Determination of serum prolactin levels in post-menopausal women is of practical clinical value. (authors)

Normal weight polycystic ovary syndrome (PCOS) women may have altered adipose structure-function underlying metabolic dysfunction. This study examines whether adipose structure-functional changes exist in normal weight PCOS women and correlate with hyperandrogenism and/or hyperinsulinemia. This is a prospective cohort study. The setting was an academic medical center. Six normal weight PCOS women and 14 age- and body mass index-matched normoandrogenic ovulatory (NL) women were included. All women underwent circulating hormone and metabolic measurements; frequently sampled intravenous glucose tolerance testing; total body dual-energy x-ray absorptiometry; abdominal magnetic resonance imaging; and SC abdominal fat biopsy. Circulating hormones and metabolites, body fat and its distribution, and adipocyte size were compared between PCOS and NL women, and were correlated with each other in all women. Circulating LH and androgen levels were significantly greater in PCOS than NL women, as were fasting insulin levels, pancreatic β-cell responsiveness to glucose, and total abdominal fat mass. Intra-abdominal fat mass also was significantly increased in PCOS women and was positively correlated with circulating androgen, fasting insulin, triglyceride, and non-high-density lipoprotein cholesterol levels in all women. SC abdominal fat mass was not significantly increased in PCOS women, but contained a greater proportion of small SC abdominal adipocytes that positively correlated with serum androgen levels in all women. Hyperandrogenism in normal weight PCOS women is associated with preferential intra-abdominal fat deposition and an increased population of small SC abdominal adipocytes that could constrain SC adipose storage and promote metabolic dysfunction.

Excessive weight gain during pregnancy and subsequent postpartum weight retention may contribute to the epidemic of obesity among women of childbearing age. Preventing excessive gestational weight gain (GWG) to optimize maternal, fetal and infant wellbeing is therefore of great importance. A number...... of dietary interventions in this area has been conducted with inconsistent results, which has made it difficult to identify effective strategies to prevent excessive weight gain during pregnancy among normal weight, overweight and obese women.

Full Text Available In an ethnically homogeneous population of women living in Tuscany, Italy, the relationships between age, body weight, bone mineral density and the vitamin D receptor (VDR gene polymorphism were studied, with the objective of recognizing patients at risk for osteoporosis. In 275 women bone mineral density was measured by Dual Energy X-rays Absorptiometry (DEXA. In 50 of them the individual genetic pattern for VDR was evaluated by DNA extraction followed by PCR amplification of the VDR gene, and digestion with the restriction enzyme BsmI. Age and bone mineral density were inversely related (R2 = 0.298. Body weight was associated with bone mineral density (R2 = 0.059, but not with age. In osteoporotic women, mean (± SD body weight was 59.9 ± 6.5 Kg, lower than that recorded in non osteoporotic women (64.2 ± 9.4 Kg, even though not significantly different (p = 0.18. No association was found between VDR gene polymorphism, bone density or body weight. The performance of anthropometric and genetic components appear to be poor, and, at least for the time being, bone mineral density measurement by means of MOC-DEXA represents the optimal method to detect women at risk for postmenopausal osteoporosis.

Full Text Available Background/Aim. Abnormal uterine bleeding is the most common problem which brings woman to the gynecologist during the postmenopausal period. The aim of this study was to define the significance of hysteroscopy as a diagnostic procedure for the evaluation of patients with postmenopausal bleeding, as well as to define it as a surgical procedure by which the cause of bleeding can be treated in most cases in the same sitting. Methods. The study involved 148 female patients referred to the Clinic for Gynecology and Obstetrics in Niš for postmenopausal bleeding in the period of 12 months. Hysteroscopy with endometrial biopsy were performed in all the patients. Biopsy materials were directed to histological examination, and the hysteroscopic and histological findings were compared afterwards. Polyps and submucous miomas were hysteroscopically removed in the same sitting and also directed to histological examination. Results. The success rate of the method was 95.1%, while complications occurred in 1.37% of the cases. The hysteroscopic findings were normal in almost 30% of the cases, and the most common pathological finding was endometrial polyp. The sensitivity of hysteroscopy in the detection of intrauterine pathology was 100%, the specificity 81%, the positive predictive value 92% and the negative predictive value 100%. In 69.7% of the patients the cause of bleeding was hysteroscopically removed. Hysteroscopy was performed in 58.1% of the patients in the same sitting, and in 11.6% of the patients after obtaining histological findings. Conclusion. Hysteroscopy is a safe, highly sensitive diagnostic procedure, thus being an ideal method for evaluation of patients with postmenopausal bleeding. The application of hysteroscopy with endometrial biopsy leads to accurate diagnosis. An adequate diagnosis is crucial for the selection of relevant treatment of postmenopausal bleeding and avoidance of unnecessary major surgical procedures. Except for being a

Objectives We aimed to examine the association between changes in psychosocial working conditions and major weight gain among midlife women and men. Furthermore, we examined the associations separately among normal- and overweight participants. Methods We used survey data among employees of the City of Helsinki, Finland, from 2000-2002 (phase 1, N=8960), 2007 (phase 2, N=7332), and 2012 (phase 3, N=6814), with a final study sample of 4369 participants. We examined changes in job strain, job demands, and job control from phase 1 to 2. We defined major weight gain as ≥10% weight gain between phases 1 and 3 based on self-reported weight (kg). We performed logistic regression analysis adjusting for baseline age, marital status, and occupational class, stratifying by gender and by baseline body mass index. Results Job demands among both genders and job strain among women was associated with major weight gain. Furthermore, increased job demands [odds ratio (OR) 1.52, 95% CI 1.05-2.20] or increased job strain (OR 1.53, 95% CI 1.11-2.11) was associated with major weight gain among overweight women. Normal-weight men reporting decreased job demands (OR 4.11, 95% CI 1.48-11.40) and overweight men reporting increasing job demands (OR 2.93, 95% CI 1.26-6.82) exhibited higher odds of major weight gain. Conclusions Associations between working conditions and weight gain appeared primarily weak. Our study suggests that overweight individuals might be at a higher risk of weight gain when facing psychosocial strain in the workplace.

Seaweed and soy foods are consumed daily in Japan, where breast cancer rates for postmenopausal women are significantly lower than in the West. Likely mechanisms include differences in diet, especially soy consumption, and estrogen metabolism. Fifteen healthy postmenopausal women participated in this double-blind trial of seaweed supplementation with soy challenge. Participants were randomized to 7 wk of either 5 g/d seaweed (Alaria) or placebo (maltodextrin). During wk 7, participants also consumed a daily soy protein isolate (2 mg isoflavones/kg body weight). After a 3-wk washout period, participants were crossed over to the alternate supplement schedule. There was an inverse correlation between seaweed dose (mg/kg body weight) and serum estradiol (E2) (seaweed-placebo = y = -2.29 x dose + 172.3; r = -0.70; P = 0.003), [corrected] which was linear across the range of weights. Soy supplementation increased urinary daidzein, glycitein, genistein, and O-desmethylangolensin (P = 0.0001) and decreased matairesinol and enterolactone (P seaweed plus soy (SeaSoy) increased urinary excretion of 2-hydroxyestrogen (2-OHE) (P = 0.0001) and the ratio of 2-OHE:16alpha-hydroxyestrone (16alphaOHE(1)) (P = 0.01). For the 5 equol excretors, soy increased urinary equol excretion (P = 0.0001); the combination of SeaSoy further increased equol excretion by 58% (P = 0.0001). Equol producers also had a 315% increase in 2:16 ratio (P = 0.001) with SeaSoy. Seaweed favorably alters estrogen and phytoestrogen metabolism and these changes likely include modulation of colonic bacteria.

Normal-weight women frequently restrict their caloric intake and exercise, but little is known about the effects on body weight, body composition and metabolic adaptations in this population. We conducted a secondary analysis of data from a randomized controlled trial in sedentary normal-weight women. Women were assigned to a severe energy deficit (SEV: -1062±80 kcal per day; n=9), a moderate energy deficit (MOD: -633±71 kcal per day; n=7) or energy balance (BAL; n=9) while exercising five times per week for 3 months. Outcome variables included changes in body weight, body composition, resting metabolic rate (RMR) and metabolic hormones associated with energy conservation. Weight loss occurred in SEV (-3.7±0.9 kg, P0.33). RMR decreased by -6±2% in MOD (P=0.020). In SEV, RMR did not change on a group level (P=0.66), but participants whose RMR declined lost more weight (P=0.020) and had a higher baseline RMR (P=0.026) than those whose RMR did not decrease. Characteristic changes in leptin (P=0.003), tri-iodothyronine (P=0.013), insulin-like growth factor-1 (P=0.016) and ghrelin (P=0.049) occurred only in SEV. The energy deficit and adaptive changes in RMR explained 54% of the observed weight loss. In normal-weight women, caloric restriction and exercise resulted in less-than-predicted weight loss. In contrast to previous literature, weight loss consisted almost exclusively of fat mass, whereas fat-free mass was preserved.

Purpose Determine 1) if levels of the glycocalyx membrane mucins, MUC1 and MUC16, and the secreted goblet cell mucin MUC5AC are altered in conjunctival cells and tears of postmenopausal women presenting with a history of non-Sjögren's dry eye, and 2) if mucin levels correlate with dry eye clinical diagnostic data. Methods Eighty-four postmenopausal women with a history of non-Sjögren's dry eye and 30 normal subjects were recruited for this study. Impression cytology samples were collected for mucin mRNA and protein analysis. Tears were collected for mucin protein assay. qPCR, western blot, and ELISA assays were used to quantitate MUC1, MUC16 and MUC5AC levels. Results Postmenopausal women with a history of dry eye displayed significantly increased MUC1 mRNA expression and cellular protein compared to normal subjects (Pdry eye patients with a history of dry eye may be a compensatory response to irritation and inflammation associated with the disease. Understanding the pattern of mucin expression associated with dry eye pathology may clarify factors involved in the progression of the disease and enhance the development of targeted therapies.

Diffusion-weighted imaging (DWI) provides information about tissue maturation not seen on conventional magnetic resonance imaging. The aim of this study is to analyze the evolution over time of the apparent diffusion coefficient (ADC) of normal fetal brain in utero. DWI was performed on 78 fetuses, ranging from 23 to 37 gestational weeks (GW). All children showed at follow-up a normal neurological evaluation. ADC values were obtained in the deep white matter (DWM) of the centrum semiovale, the frontal, parietal, occipital and temporal lobe, in the cerebellar hemisphere, the brainstem, the basal ganglia (BG) and the thalamus. Mean ADC values in supratentorial DWM areas (1.68 {+-} 0.05 mm{sup 2}/s) were higher compared with the cerebellar hemisphere (1.25 {+-} 0.06 mm{sup 2}/s) and lowest in the pons (1.11 {+-} 0.05 mm{sup 2}/s). Thalamus and BG showed intermediate values (1.25 {+-} 0.04 mm{sup 2}/s). Brainstem, cerebellar hemisphere and thalamus showed a linear negative correlation with gestational age. Supratentorial areas revealed an increase in ADC values, followed by a decrease after the 30th GW. This study provides a normative data set that allows insights in the normal fetal brain maturation in utero, which has not yet been observed in previous studies on premature babies. (orig.)

This study aims to examine the independent and combined impact of hypocaloric diet and low-intensity resistance exercise training (LIRET) on aortic hemodynamics and appendicular skeletal muscle mass (ASM) in obese postmenopausal women. Forty-one obese postmenopausal women (mean [SD] age, 54 [1] y) were randomly assigned to LIRET (n = 13), diet (n = 14), or diet + LIRET (n = 14). Body weight, waist circumference, aortic systolic blood pressure, aortic pulse pressure, augmentation index, subendocardial viability ratio (SEVR; myocardial perfusion), and heart rate (HR) were measured before and after 12 weeks. ASM was assessed by dual-energy x-ray absorptiometry. Body weight (P diet and diet + LIRET compared with no changes after LIRET. ASM did not change after diet + LIRET, and the decrease observed after diet (P diet (P diet + LIRET (P diet and diet + LIRET, but not after LIRET. SEVR (P diet groups, whereas HR (P diet. Changes in SEVR (P diet were different compared with LIRET. The augmentation index did not change in any group. Our findings suggest that diet-induced weight loss may reduce cardiovascular risk by improving SEVR via HR and aortic pulse pressure reductions in obese postmenopausal women. LIRET prevents ASM loss associated with hypocaloric diet but has no additive effects on aortic hemodynamics.

Abdominal fat accumulation after menopause is associated with low-grade inflammation and increased risk of metabolic disorders. Effective long-term lifestyle treatment is therefore needed. Seventy healthy postmenopausal women (age 60 ± 5.6 years) with BMI 32.5 ± 5.5 were randomized to a Paleolithic-type diet (PD) or a prudent control diet (CD) for 24 months. Blood samples and fat biopsies were collected at baseline, 6 months, and 24 months to analyze inflammation-related parameters. Android fat decreased significantly more in the PD group (P = 0.009) during the first 6 months with weight maintenance at 24 months in both groups.

Grimes, Julia P; Wimalawansa, Sunil J

2003-06-01

Bone loss associated with osteoporosis occurs with high frequency among the elderly and often results in debilitating fractures. A combination of lifestyle behaviors, genetic predisposition, and disease processes contributes to bone metabolism. Therefore, any discussion regarding bone health must address these factors. The impact of menopause on bone turnover has been generally well studied and characterized. Breastfeeding places significant stress on calcium metabolism and, as a consequence, directly influences bone metabolism. The most significant factors affecting bone mineral density (BMD) and bone metabolism are the duration and frequency of lactation, the return of menses, and pre-pregnancy weight. Although transient, lactation is associated with bone loss. As clinical guidelines and public health policies are being formulated, there is a compelling need for further investigation into the relationship of lactation, BMD, and subsequent risk of osteoporosis. Better understanding of this relationship will provide new opportunities for early intervention and ultimately help in the prevention of bone loss in postmenopausal women.

Full Text Available Introduction: Single nucleotide polymorphism (SNP at the collagen type I alpha 1 gene (COL1A1 rs1800012 has been widely studied and has shown an association with bone mineral density (BMD and fractures. A minor allele TT of this SNP was found to be greatly overrepresented in individuals with fractures compared to controls, thus becoming a good predictor of  increased fracture risk. The aim of this investigation was to evaluate potential association between COL1A1 gene polymorphism and osteoporosis in Kazakh postmenopausal women.Methods: The study population included 103 postmenopausal women recruited from Pavlodar and Almaty clinics. BMD was measured using DEXA. Genomic DNA was extracted from peripheral venous blood of study participants with Wizard® Genomic DNA Purification Kit (Promega, USA. Detection of COL1A1 +1245G/T (Sp1 polymorphism was done by the TaqMan® SNP Genotyping Assay of real-time PCR.Results: Densitometry results revealed 36 osteoporotic, 42 osteopenic, and 25 normal postmenopausal women. Data analysis of 1245G>T polymorphism in COL1A1 gene in the group of women with osteopenia and osteoporosis revealed deviation from Hardy-Weinberg equilibrium. The mutant TT genotype was prevalent compared to the heterozygous genotype GT in both groups. Distributions were 83% GG, 3% GT, and 14% TT in the group with osteopenia and 80% GG, 6% GT, and 14% TT in the group with osteoporosis. The distribution of genotypes frequency in the group of normal postmenopausal women was 76% GG, 16% GT, and 8% TT.Conclusion: These results suggest that TT genotype of COL1A1 +1245G/T (Sp1 polymorphism is associated with risk of postmenopausal osteoporosis in Kazakh women. Further studies involving a larger number of women are needed to clarify the relationship of this polymorphism with risk of osteoporosis.

To assess how pre-pregnancy body mass index (BMI) affects pregnancy outcome and total gestational weight gain (GWG) in a cohort of women with gestational diabetes (GDM). Pregnant women at 24-28 gestational weeks diagnosed with GDM were classified as normal weight (pre-pregnancy BMI, 18.5-24.9 kg/m(2) ) or overweight (pre-pregnancy BMI, 25.0-29.9 kg/m(2) ). GWG was derived from the self-reported pre-pregnancy and pre-delivery weights, and analyzed using 2009 Institute of Medicine categories. A total of 106 GDM women were categorized as normal weight (n = 79) or overweight (n = 27). No statistically significant differences were found between the groups in terms of various obstetrical and neonatal outcomes. Higher pre-pregnancy BMI, however, was associated with excessive GWG during pregnancy (difference between groups, P = 0.013). Furthermore, pre-pregnancy BMI (OR, 0.529; 95%CI: 0.377-0.742; P = 0.000) and pre-pregnancy overweight (OR, 3.825; 95%CI: 1.469-9.959; P = 0.006) were independent factors of GWG. Among Chinese GDM women, overweight GDM mothers gain excessive weight during pregnancy. Regulation of pre-pregnancy bodyweight might be an appropriate precaution against excessive GWG. © 2016 Japan Society of Obstetrics and Gynecology.

A large number of diabetes patients suffer from major depression and are at high risk of mortality. In view of a role of leptin in diabetes, depression and energy homeostasis, the present study concerns circulating levels of leptin in different BMI groups of un-depressed and depressed diabetes patients. Six hundred thirty male and female patients with a primary diagnosis of diabetes were grouped according to BMI and with or without clinical symptoms of depression. Age matched healthy, normal weight male and female volunteers without clinical symptoms of depression or diabetes were taken as controls. Blood samples were obtained after an overnight fast of 12 h. Serum was stored for the determination of leptin and glucose. We found that there were more female than male diabetes patients with comorbid depression. Fasting leptin was higher in normal weight non-diabetes women than men; but comparable in normal weight men and women diabetes patients. Fasting glucose levels were higher in diabetes than non diabetes groups; values were comparable in men and women. Depression was associated with a decrease and increase in leptin respectively in normal-overweight and obese men and women diabetes patients. Glucose levels were also higher in obese depressed than un-depressed diabetes patients. The results suggested that the female gender is at greater risk to comorbid diabetes with depression. Adipo-insular axis plays an important role in diabetes, associated depression and in the greater risk of the female gender to comorbid diabetes with depression.

Context: Normal weight polycystic ovary syndrome (PCOS) women may have altered adipose structure-function underlying metabolic dysfunction. Objective: This study examines whether adipose structure-functional changes exist in normal weight PCOS women and correlate with hyperandrogenism and/or hyperinsulinemia. Design: This is a prospective cohort study. Setting: The setting was an academic medical center. Patients: Six normal weight PCOS women and 14 age- and body mass index-matched normoandrogenic ovulatory (NL) women were included. Intervention(s): All women underwent circulating hormone and metabolic measurements; frequently sampled intravenous glucose tolerance testing; total body dual-energy x-ray absorptiometry; abdominal magnetic resonance imaging; and SC abdominal fat biopsy. Main Outcome Measure(s): Circulating hormones and metabolites, body fat and its distribution, and adipocyte size were compared between PCOS and NL women, and were correlated with each other in all women. Results: Circulating LH and androgen levels were significantly greater in PCOS than NL women, as were fasting insulin levels, pancreatic β-cell responsiveness to glucose, and total abdominal fat mass. Intra-abdominal fat mass also was significantly increased in PCOS women and was positively correlated with circulating androgen, fasting insulin, triglyceride, and non-high-density lipoprotein cholesterol levels in all women. SC abdominal fat mass was not significantly increased in PCOS women, but contained a greater proportion of small SC abdominal adipocytes that positively correlated with serum androgen levels in all women. Conclusion: Hyperandrogenism in normal weight PCOS women is associated with preferential intra-abdominal fat deposition and an increased population of small SC abdominal adipocytes that could constrain SC adipose storage and promote metabolic dysfunction.

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

Postmenopausal bleeding (PMB) can be the first sign of endometrial cancer. In case of thickened endometrium, endometrial sampling is often used in these women. In this systematic review, we studied the accuracy of endometrial sampling for the diagnoses of endometrial cancer, atypical hyperplasia and endometrial disease (endometrial pathology, including benign polyps). We systematically searched the literature for studies comparing the results of endometrial sampling in women with postmenopausal bleeding with two different reference standards: blind dilatation and curettage (D&C) and hysteroscopy with histology. We assessed the quality of the detected studies by the QUADAS-2 tool. For each included study, we calculated the fraction of women in whom endometrial sampling failed. Furthermore, we extracted numbers of cases of endometrial cancer, atypical hyperplasia and endometrial disease that were identified or missed by endometrial sampling. We detected 12 studies reporting on 1029 women with postmenopausal bleeding: five studies with dilatation and curettage (D&C) and seven studies with hysteroscopy as a reference test. The weighted sensitivity of endometrial sampling with D&C as a reference for the diagnosis of endometrial cancer was 100% (range 100-100%) and 92% (71-100) for the diagnosis of atypical hyperplasia. Only one study reported sensitivity for endometrial disease, which was 76%. When hysteroscopy was used as a reference, weighted sensitivities of endometrial sampling were 90% (range 50-100), 82% (range 56-94) and 39% (21-69) for the diagnosis of endometrial cancer, atypical hyperplasia and endometrial disease, respectively. For all diagnosis studied and the reference test used, specificity was 98-100%. The weighted failure rate of endometrial sampling was 11% (range 1-53%), while insufficient samples were found in 31% (range 7-76%). In these women with insufficient or failed samples, an endometrial (pre) cancer was found in 7% (range 0-18%). In women with

Urinary tract infection (UTI) is the most common bacterial infection in women in general and in postmenopausal women in particular. Two groups of elderly women with recurrent UTI should be differentiated regarding age and general status: healthy, young postmenopausal women aged 50 to 70 years who are neither institutionalized or catheterized and elderly institutionalized women with or without a catheter. Bacteriuria occurs more often in elderly functionally impaired women, but in general it is asymptomatic. However, the risk factors associated with recurrent UTI in elderly women are not widely described. In a multivariate analysis it was found that urinary incontinence, a history of UTI before menopause, and nonsecretor status were strongly associated with recurrent UTI in young postmenopausal women. Another study described the incidence and risk factors of acute cystitis among nondiabetic and diabetic postmenopausal women. Independent predictors of infection included insulin-treated patients and a lifetime history of urinary infection. Borderline associations included a history of vaginal estrogen cream use in the past month, kidney stones, and asymptomatic bacteriuria at baseline. Another important factor in postmenopausal women is the potential role that estrogen deficiency plays in the development of bacteriuria. There are at least two studies showing a beneficial effect of estrogen in the management of recurrent bacteriuria in elderly women. One of these studies showed that vaginal estrogen cream reduced vaginal pH from 5.5±0.7 to 3.6±1.0, restored lactobacillus, and decreased new episodes of UTI. Another study reported similar results using an estriol vaginal ring. However, contradictory results are found in the literature. For example, additional studies found that the use of estriol-containing vaginal pessaries was less effective than oral nitrofurantoin macrocrystals in preventing UTI in postmenopausal women. Two other studies also did not find any

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

Stress has been supposed to increase appetite. The biological basis of this phenomenon may be a stress-induced alteration of the secretion of GUT peptides such as ghrelin. Stress-induced changes in ghrelin secretion could be a biological basis of overeating and a factor contributing to the development of obesity. Aim of the study was to analyze the effect of acute psychosocial stress on ghrelin secretion in obese and normal weight women. We compared pre- and postprandial plasma ghrelin secretion of 42 obese and 43 normal weight women in a randomized crossover design. Ghrelin and cortisol concentrations were measured and ratings of stress were also recorded in response to a psychological stressor (Trier Social Stress Test, TSST). Ghrelin samples were collected in the fasting state one time before participating in the TSST and one time before a control session. After the TSST, respectively, control session participants had a standardized ad libitum meal. 30 and 60 min after the TSST, respectively, control session preprandial ghrelin was measured again. Obese women showed lower pre- and postprandial release of ghrelin than normal weight controls. Moreover, obese women showed inhibited postprandial decrease of ghrelin secretion. Stress did not affect postprandial ghrelin secretion, but inhibited food intake in all subjects. The present data provide further evidence of altered ghrelin release in obesity. Acute stress did not affect postprandial ghrelin secretion, but inhibited food intake in all subjects. Results are discussed with regard to biological and psychological regulation of hunger and satiety in obesity.

To determine the 6-month follow-up effects after intentional 6-month weight loss alone (WL) and after weight loss with aerobic exercise (AEX + WL) on body composition, glucose metabolism, and cardiovascular disease risk factors in older postmenopausal women and to identify the mechanisms for weight regain. Women (n = 65, BMI > 25 kg/m 2 ) underwent maximal oxygen consumption testing, dual-energy x-ray absorptiometry, computed tomography scans, and oral glucose tolerance tests before and after 6 months of AEX + WL or WL and at 12 months ad libitum follow-up. Insulin sensitivity (M) (hyperinsulinemic-euglycemic clamp) was measured at baseline and 6 months. Thirty WL and thirty-five AEX + WL women completed a follow-up at 12 months. Similar weight loss was observed (-8%) in both groups from 0 to 6 months. Total fat mass, fat-free mass, visceral fat area, subcutaneous abdominal and midthigh fat areas, fasting glucose, insulin levels, homeostatic model assessment of insulin resistance (HOMA-IR), insulin areas under the curve, and triglyceride levels decreased similarly after WL and AEX + WL and remained lower at 12 months than at baseline, despite weight regain at 12 months. Initial M was associated with weight regain (r = -0.40, P < 0.01). Weight regain was related to independent changes in leptin and HOMA-IR from 6 to 12 months in a multiple regression model (r = 0.77, P < 0.0001). Reductions in body fat and improvements in insulin sensitivity after AEX + WL and WL were maintained at 12 months despite modest weight regain. Baseline insulin resistance partially predicted the magnitude of weight regain in postmenopausal women. © 2017 The Obesity Society.

Central arterial stiffness is associated with incident hypertension and negative cardiovascular outcomes. Obese individuals have higher central blood pressure (BP) and central arterial stiffness than their normal-weight counterparts, but it is unclear whether obesity also affects hemodynamics and central arterial stiffness after maximal exercise. We evaluated central hemodynamics and arterial stiffness during recovery from acute maximal aerobic exercise in obese and normal-weight individuals. Forty-six normal-weight and twenty-one obese individuals underwent measurements of central BP and central arterial stiffness at rest and 15 and 30 min following acute maximal exercise. Central BP and normalized augmentation index (AIx@75) were derived from radial artery applanation tonometry, and central arterial stiffness was obtained via carotid-femoral pulse wave velocity (cPWV) and corrected for central mean arterial pressure (cPWV/cMAP). Central arterial stiffness increased in obese individuals but decreased in normal-weight individuals following acute maximal exercise, after adjusting for fitness. Obese individuals also exhibited an overall higher central BP ( P  <   0.05), with no exercise effect. The increase in heart rate was greater in obese versus normal-weight individuals following exercise ( P  <   0.05), but there was no group differences or exercise effect for AIx@75 In conclusion, obese (but not normal-weight) individuals increased central arterial stiffness following acute maximal exercise. An assessment of arterial stiffness response to acute exercise may serve as a useful detection tool for subclinical vascular dysfunction. © 2017 The Authors.

Full Text Available Pupose: Although there are reports of vitamin D (VitD insufficiency in immune-mediated hypothyroidism, an association between VitD and thyroid-stimulating hormone (TSH levels has yet to be shown. We aim to examine VitD and TSH levels among postmenopausal women, as both conditions are more prevalent in elderly women. Methods: The clinic records of postmenopausal women during their routine maintenance visits were reviewed. All patients were examined for the symptoms related to thyroid function and osteoporosis. Participants were divided into three subgroups according to their TSH levels (below 4.0 mIU/L. Patient characteristics and VitD levels were compared between these subgroups. Multivariate linear regression model was constructed using serum VitD and serum TSH as the dependent variables to identify factors independently associated with these laboratory values. Results: Two-hundred and nighty nine postmenopausal women were included. Average age was 62.2±7.5 years old. VitD was insufficient (10-30 ng/mL in 12.0% and deficient (<10 ng/mL in 60.9% of the participants. In 11.3%, TSH was low and in 7.6% of women, TSH was high, while the remaining 80.1%, had normal TSH levels. Subjects with low TSH had significantly higher VitD concentrations (34.2±29.1 ng/mL compared to the other two groups (P-value: 0.039. In multivariate regression analysis, TSH was not a contributing factor, as age was the only significant predictor of VitD levels. Meanwhile, no predictor (including age and VitD was identified for TSH levels in linear regression analysis. Conclusion: Age was the only independent predictor of serum VitD in this study population. Though suppressed TSH was associated with higher VitD levels, the association was not linear between TSH and VitD in postmenopausal women.

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

Full Text Available Background and Aims: Obese patients are more vulnerable to residual neuromuscular block (NMB and its associated complications in the post-operative period. This study was carried out to compare neostigmine induced reversal of vecuronium in normal weight, overweight and obese female patients, objectively using neuromuscular (NM monitoring. Methods: Twenty female patients each belonging to normal weight, overweight and obese, based on body mass index, requiring general anaesthesia were recruited for this prospective cross sectional study. NMB was induced with vecuronium (0.1 mg/kg dose based on patient′s real body weight (RBW and monitored using acceleromyographic train of four (TOF. All patients received neostigmine 40 μg/kg and glycopyrrolate 10 μg/kg at 25% of spontaneous recovery of first twitch height (T1 of TOF (DUR 25% and were allowed to recover to TOF ratio of 0.9. Statistical analysis was done using analysis of variance test. Results: Recovery of TOF ratio to 0.5 was comparable in all three groups. Recovery of TOF ratio to 0.7 was delayed in obese (9.82 ± 3.21 min compared with normal weight group (7.50 ± 2.52 min. Recovery of TOF to 0.9 was significantly delayed in both overweight (12.18 ± 4.29 min and obese patients (13.78 ± 4.30 min. DUR 25% was significantly longer in overweight (mean, standard deviation [range]; 30.10 [19-40 min] and obese (28.8 [12-45 min] compared with normal weight patients (22.75 [16-30 min]. Conclusion: In overweight and obese patients, when vecuronium induction dose is based on RBW, neostigmine induced recovery of NMB is delayed in late phases (TOF 0.7-0.9, which may result in vulnerability for associated complications of incomplete recovery. Ensuring safe recovery thus requires objective NM monitoring.

A retrospective and analytical cross-sectional study, with a non-probabilistic sampling technique in women rightful claimants of the IMSS, San Luis Potosi. In all of them the bone mineral density was measured with X-ray dual absorptiometry in the distal forearm. Reproductive history and age of menarche were obtained by the addition of these items to the previously validated Albrand questionnaire. Women were divided into groups according to the number of pregnancies in: normal parity (0 to 3 childbirths) conformed by 112 patients (46%) and multiparity (> or = 4 pregnancies), 131 women (54%). In relation to menarche with an average of 12.98 years, from this number we divided them in: early menarche ( or = 13 yrs). 243 women were studied, with an average of age of 55.92, rank 31 to 80 years. Using the criteria of the World Health Organization, 18% of postmenopausal women had osteoporosis, 39% had osteopenia and 43% had bone normality. No association was found between the number of pregnancies and osteoporosis. Additionally we observed that the women who had four or more children were older than the other women, average 57.42 against 54.16. Also there was significant negative correlation (r = -0.43) between age and densitometry. We found that an age greater to 13 years in the appearance of the menarche was related to osteoporosis (OR 4.46, p: 0.035). In postmenopausal women a menarche older than 13 years is a risk factor for osteoporosis.

Context: The clinical consequences of insulin resistance and hyperinsulinemia on bone remain largely unknown. Objective: The objective of the study was to evaluate the effect of insulin resistance on peripheral bone geometry, volumetric bone mineral density (vBMD), bone microarchitecture, and estimated bone strength. Design, Setting, and Participants: This cross-sectional study included 146 postmenopausal, nondiabetic Caucasian women (mean age 60.3 ± 2.7 y) who were participating in the Study of Women's Health Across the Nation. Interventions: There were no interventions. Main Outcome Measures: High-resolution peripheral quantitative computed tomography was used to assess bone density and microstructure at the distal radius and tibia. Fasting insulin and glucose were measured and insulin resistance was estimated using homeostasis model assessment of insulin resistance (HOMA-IR), with higher values indicating greater insulin resistance. Results: There was a negative association between HOMA-IR and bone size and a positive association between HOMA-IR and total vBMD, trabecular vBMD, trabecular thickness, and cortical thickness at the radius and tibia. These relationships remained, even after adjusting for body weight and other potential covariates (eg, time since menopause, cigarette smoking, physical activity, prior use of osteoporosis medications or glucocorticoids). Conclusions: In nondiabetic, postmenopausal women, insulin resistance was associated with smaller bone size, greater volumetric bone mineral density, and generally favorable bone microarchitecture at weight-bearing and nonweight-bearing skeletal sites. These associations were independent of body weight and other potential covariates, suggesting that hyperinsulinemia directly affects bone structure independent of obesity and may explain, in part, the higher trabecular bone density and favorable trabecular microarchitecture seen in individuals with type 2 diabetes mellitus.

Sarcopenia and insulin resistance are common co-morbidities in the elderly and are known to be associated with vitamin D deficiency. However, no previous studies have investigated interactions between all three of these factors. We aimed to investigate the relationship between 25-hydroxyvitamin D concentration, sarcopenia, and insulin resistance in postmenopausal Korean women. This study used data from the Korea National Health and Nutrition Examination Survey 2008-2011. Participants were 3744 postmenopausal Korean women. Sarcopenia was defined as appendicular skeletal muscle mass divided by body weight >1 standard deviation below the mean for women aged 20-40 years. The serum 25-hydroxyvitamin D and fasting insulin levels were measured, and insulin resistance was calculated using the formula: fasting plasma glucose (mg/dl) × fasting insulin (mIU/l)/405. We found a strong inverse association between 25-hydroxyvitamin D concentration and sarcopenia in postmenopausal Korean women (p = 0.0009). There was also a significant association between sarcopenia and insulin resistance, independent of vitamin D and obesity status (p < 0.0001). However, there was no significant association between 25-hydroxyvitamin D concentration and insulin resistance. In the subgroup analysis, insulin resistance was found to be determined by sarcopenic rather than vitamin D status. Sarcopenia was associated with both insulin resistance and 25-hydroxyvitamin D concentration in postmenopausal Korean women, regardless of obesity status. However, 25-hydroxyvitamin D concentration was not associated with insulin resistance. Sarcopenia is therefore of greater clinical importance due to its close relationship with insulin resistance.

A number of clinical decision tools for osteoporosis risk assessment have been developed to select postmenopausal women for the measurement of bone mineral density. We developed and validated machine learning models with the aim of more accurately identifying the risk of osteoporosis in postmenopausal women compared to the ability of conventional clinical decision tools. We collected medical records from Korean postmenopausal women based on the Korea National Health and Nutrition Examination Surveys. The training data set was used to construct models based on popular machine learning algorithms such as support vector machines (SVM), random forests, artificial neural networks (ANN), and logistic regression (LR) based on simple surveys. The machine learning models were compared to four conventional clinical decision tools: osteoporosis self-assessment tool (OST), osteoporosis risk assessment instrument (ORAI), simple calculated osteoporosis risk estimation (SCORE), and osteoporosis index of risk (OSIRIS). SVM had significantly better area under the curve (AUC) of the receiver operating characteristic than ANN, LR, OST, ORAI, SCORE, and OSIRIS for the training set. SVM predicted osteoporosis risk with an AUC of 0.827, accuracy of 76.7%, sensitivity of 77.8%, and specificity of 76.0% at total hip, femoral neck, or lumbar spine for the testing set. The significant factors selected by SVM were age, height, weight, body mass index, duration of menopause, duration of breast feeding, estrogen therapy, hyperlipidemia, hypertension, osteoarthritis, and diabetes mellitus. Considering various predictors associated with low bone density, the machine learning methods may be effective tools for identifying postmenopausal women at high risk for osteoporosis.

Galanin is believed to play a role in the control of eating behavior. No information is available on its concentrations in the biological fluids in human obesity, and this study aimed to clarify this. We measured plasma galanin and serum insulin levels in 30 obese, 35 normal weight and 11 anorectic women. Mean galanin values were quite similar in obese and control subjects (76.8 +/- 3.20 vs 76.1 +/- 2.33 pg/ml) and only slightly reduced in anorectic patients (67.9 +/- 2.30 pg/ml). Insulin levels were significantly increased and decreased in obese and anorectic patients, respectively, compared to controls. Insulin correlated positively with BMI in the whole group of subjects studied (r = 0.72, P < 0.0001) and in the obese subgroup (r = 0.56, P < 0.02). No correlations could be detected between WH ratio, insulin and galanin concentrations and between galanin and BMI. In conclusion, plasma galanin concentrations appear to be comparable in obese, normal weight and anorectic subjects. This does not exclude a role of galanin in the regulation of eating behavior since variations of the peptide in discrete brain areas may not be detectable in general circulation and peripheral sources of the peptide may contribute to its plasma levels. Also, our data suggest that galanin does not play a major role in the regulation of insulin secretion in humans.

Objective: To evaluate the relationship between isokinetically and isometrically determined muscle strength and BMD in postmenopausal women of different age groups. Methods: Healthy postmenopausal women (n = 293; mean age, 54.22 ± 3.85 years were enrolled in this study. They were grouped by age according to World Health Organization life expectancy: 45–50 years, 51–53 years, 54–56 years, 57–59 years, and 60–64 years. Total BMD, L2–4 BMD, and femoral neck BMD were measured by dual-energy X-ray bone densitometry; isokinetic and isometric muscle strength of the right hip and trunk muscles were measured during contractile exercise. Stepwise regression analysis was used to examine the relationships between BMD and strength measures, controlling for subject age and years since menopause. Results: Results of stepwise regression showed that hip extensor and flexor strength at 120°/second and back extend strength at 30°/second accounted for 26% total BMD variance among menopausal subjects, 19% L2–4 BMD variance, and 15% femoral neck BMD variance; in postmenopausal women of different age groups, hip extensor and flexor strength at 120°/second and back extend strength at 30°/second accounted for 25%–35% total BMD variance. Conclusion: Different optimal strength

To Analyze the transvaginal ultrasonographic(TVUS)findings of the cystic adnexal masses in postmenopausal women for differentiation of benign and malignant masses. We retrospectively reviewed the TVUS images of surgically proven 142 cystic adnexal masses in 125 patients. The masses were classified according to the pathologic findings. The size, the internal echogenicity, the internal septation, the external wall of the masses on US were analyzed and scored using Multicenter scoring system. Serum CA-125 concentration was also recorded. At surgery of 142 masses, 125 benign (88%), and 17 borderline/malignant masses (12%) were found. Among 125 benign masses, 88 masses were larger than 5 cm, 125 had smooth external wall, 109 had absence or thin internal septation, and 107 had anechoic or homogenous low internal echogenicity. Of the 17 borderline/malignant masses, there were 17 masses larger than 5 cm, 2 with smooth external wall, 12 without or with thin internal septation, and 7 with anechoic or homogenous low internal echogenicity. Multicenter score was below 8 in all benign masses, and in 4 borderline/malignant masses. Serum CA-125 concentration with normal range was in 90 patients with benign masses, and in 2 patients with borderline/malignant masses. Cystic adnexal masses with smooth external wall and internal septation, internal echogenic portion less than 10%, score below 8 on TVUS would be diagnosed as benign masses in postmenopausal women with normal serum CA-125 concentration.

Possible benefits of vitamin K on bone health, fracture risk, markers of bone formation and resorption, cardiovascular health, and cancer risk in postmenopausal women have been investigated for over three decades; yet there is no clear evidence-based universal recommendation for its use. Interventional studies showed that vitamin K1 provided significant improvement in undercarboxylated osteocalcin (ucOC) levels in postmenopausal women with normal bone mineral density (BMD); however, there are inconsistent results in women with low BMD. There is no study showing any improvement in bone-alkaline-phosphatase (BAP), n-telopeptide of type-1 collagen (NTX), 25-hydroxy-vitamin D, and urinary markers. Improvement in BMD could not be shown in the majority of the studies; there is no interventional study evaluating the fracture risk. Studies evaluating the isolated effects of menatetrenone (MK-4) showed significant improvement in osteocalcin (OC); however, there are inconsistent results on BAP, NTX, and urinary markers. BMD was found to be significantly increased in the majority of studies. The fracture risk was assessed in three studies, which showed decreased fracture risk to some extent. Although there are proven beneficial effects on some of the bone formation markers, there is not enough evidence-based data to support a role for vitamin K supplementation in osteoporosis prevention among healthy, postmenopausal women receiving vitamin D and calcium supplementation. Interventional studies investigating the isolated role of vitamin K on cardiovascular health are required. Longterm clinical trials are required to evaluate the effect of vitamin K on gynecological cancers. MK-4 seems safe even at doses as high as 45 mg/day. Copyright © 2013 Elsevier Ireland Ltd.

Full Text Available Low Birth weight infants are at risk of many problems. Therefore their outcome must evaluate in different ages especially in school age. In this study we determined prevalence of ophthalmic, hearing, speaking and school readiness problems in children who were born low birth weight and compared them with normal birth weight children. In a cross-sectional and retrospective study, all Primary School children referred to special educational organization center for screening before entrance to school were elected in Mashhad, Iran. In this study 2400 children enrolled to study and were checked for ophthalmic, hearing, speaking and school readiness problems by valid instrument. Data were analyzed by SPSS 11.5. This study showed that 8.3% of our population had birth weight less than 2500 gram. Visual impairment in LBW (Low Birth Weight and NBW (Normal Birth Weight was 8.29% vs. 5.74% and there was statistically significant difference between them (P=0.015. Hearing problem in LBW and NBW was 2.1% vs. 1.3 and it was not statistically significant. Speaking problem in LBW and NBW was 2.6% vs. 2.2% and it was not statistically significant. School readiness problem in LBW and NBW was 12.4% vs. 5.8% and it was statistically significant (P<0.001. According to the results, neurological problems in our society is more than other society and pay attention to this problem is critical. We believe that in our country, it is necessary to provide a program to routinely evaluate LBW children.

Weight loss may improve glucose control in persons with type 2 diabetes. The effects of fat quality, as opposed to quantity, on weight loss are not well understood. We compared the effects of 2 dietary oils, conjugated linoleic acid (CLA) and safflower oil (SAF), on body weight and composition in obese postmenopausal women with type 2 diabetes. This was a 36-wk randomized, double-masked, crossover study. Fifty-five obese postmenopausal women with type 2 diabetes received SAF or CLA (8 g oil/d) during two 16-wk diet periods separated by a 4-wk washout period. Subjects met monthly with the study coordinator to receive new supplements and for assessment of energy balance, biochemical endpoints, or anthropometric variables. Thirty-five women completed the 36-wk intervention. Supplementation with CLA reduced body mass index (BMI) (P = 0.0022) and total adipose mass (P = 0.0187) without altering lean mass. The effect of CLA in lowering BMI was detected during the last 8 wk of each 16-wk diet period. In contrast, SAF had no effect on BMI or total adipose mass but reduced trunk adipose mass (P = 0.0422) and increased lean mass (P = 0.0432). SAF also significantly lowered fasting glucose (P = 0.0343) and increased adiponectin (P = 0.0051). No differences were observed in dietary energy intake, total fat intake, and fat quality in either diet period for either intervention. Supplementation with CLA and SAF exerted different effects on BMI, total and trunk adipose mass, and lean tissue mass in obese postmenopausal women with type 2 diabetes. Supplementation with these dietary oils may be beneficial for weight loss, glycemic control, or both.

Dental caries and deviations from normal weight are two conditions which share several broadly predisposing factors. So it's important to understand any relationship between dental state and body weight if either is to be managed appropriately. The study was done to find out the correlation between body mass index (BMI), diet, and dental caries among 12-15-year-old schoolgoing children in Panchkula District. A multistage sample of 12-15-year-old school children (n = 810) in Panchkula district, Haryana was considered. Child demographic details and diet history for 5 days was recorded. Data regarding dental caries status was collected using World Health Organization (1997) format. BMI was calculated and categorized according to the World Health Organization classification system for BMI. The data were subjected to statistical analysis using chi-square test and binomial regression developed using the Statistical Package for Social Sciences (SPSS) 20.0. The mean Decayed Missing Filled Teeth (DMFT) score was found to be 1.72 with decayed, missing, and filled teeth to be 1.22, 0.04, and 0.44, respectively. When the sample was assessed based on type of diet, it was found that vegetarians had higher mean DMFT (1.72) as compared to children having mixed diet. Overweight children had highest DMFT (3.21) which was followed by underweight (2.31) and obese children (2.23). Binomial regression revealed that females were 1.293 times at risk of developing caries as compared to males. Fair and poor Simplified-Oral Hygiene Index (OHI-S) showed 3.920 and 4.297 times risk of developing caries as compared to good oral hygiene, respectively. Upper high socioeconomic status (SES) is at most risk of developing caries. Underweight, overweight, and obese are at 2.7, 2.5, and 3 times risk of developing caries as compared to children with normal BMI, respectively. Dental caries and deviations from normal weight are two conditions which share several broadly predisposing factors such as diet

Inconsistent associations have been reported between diet and breast cancer. We prospectively examined the association between dietary patterns and postmenopausal breast cancer risk in a US-wide cohort study. Data were analyzed from 40 559 women who completed a self-administered 61-item Block food-frequency questionnaire in the Breast Cancer Detection Demonstration Project, 1987-1998; 1868 of those women developed breast cancer. Dietary patterns were defined by using principal components factor analysis. Cox proportional hazard regression was used to assess breast cancer risk. Three major dietary patterns emerged: vegetable-fish/poultry-fruit, beef/pork-starch, and traditional southern. The vegetable-fish/poultry-fruit pattern was associated with higher education than were the other patterns, but was similar in nutrient intake to the traditional southern pattern. After adjustment for confounders, there was no significant association between the vegetable-fish/poultry-fruit and beef/pork-starch patterns and breast cancer. The traditional southern pattern, however, was associated with a nonsignificantly reduced breast cancer risk among all cases (in situ and invasive) that was significant for invasive breast cancer (relative hazard = 0.78; 95% CI = 0.65, 0.95; P for trend = 0.003). This diet was also associated with a reduced risk in women without a family history of breast cancer (P = 0.05), who were underweight or normal weight [body mass index (in kg/m(2)) dressing intake, and possibly cabbage. The traditional southern diet or its components are associated with a reduced risk of invasive breast cancer in postmenopausal women.

Twenty women had normal body mass index (BMI, 29 ones were overweight and 29 had obesity. The body composition and BMD was studied by dual-energy X-ray absorptiometry.ResultsWomen with normal BMD had higher BMI, total and truncal fat mass, as well lean mass as compared to women with osteoporosis and osteopenia (all p <0.05. Patients with osteoporosis had a lower fat mass at the hips, compared with those with normal BMD. Total and truncal fat mass, as well as lean mass were positively correlated with BMD in the lumbar spine and proximal femur, femoral neck and radius. In multivariate regression analysis fat mass was an independent predictor for total BMD, after adjusting for age, BMI, duration of menopause, HbA1c, glomerular filtration rate and other total body composition parameters.ConclusionsIn postmenopausal type 2 diabetic women BMI and fat mass is associated positively with BMD.

Full Text Available Objective: This study was conducted aimed to compare the growth indices in 2 years old children with a history of low birth weight with normal birth weight children.Methods: Current retrospective cohort study on all two-year children with low birth weight and three times the normal weight children covered by health centers of Kahnooj, was conducted in 2015. Cares at birth, 1, 2, 4, 6, 7, 9, 12, 15, 18 and 24 months of age were studied and, child growth indices (weight, height, head circumference, along with some demographic variables were studied. Information were entered SPSS version 20 and the analysis was performed.Results: There were significant differences in children's growth of both groups in all periods of care. Despite the same slope, growth pattern in children showed a significant difference. Young mother, girl sex of baby and preterm birth are predictor factors of low birth weight.Conclusion: Trends and growth patterns of weight, height and head circumference in underweight children have significant difference with normal children and, despite the same slope, these children can not compensate for the backwardness of its growth to the age of two. So you need to plot separate growth curves for these children and, possible preventive measures should be taken to prevent bearing underweight baby.

Bone mass regulation of leptin and postmenopausal osteoporosis with obesity.

Science.gov (United States)

Legiran, Siswo; Brandi, Maria Luisa

2012-09-01

Leptin has been known to play a role in weight regulation through food intake and energy expenditure. Leptin also has an important role in bone metabolism. The role of leptin is determined by leptin receptors, either central or peripheral to the bones. We discuss the role of leptin on bone and molecular genetics of osteoporosis in postmenopausal obese women. The role of leptin in bone preserves bone mineral density (BMD) through increased OPG levels leading to bind RANKL, resulting in reducing osteoclast activity. The estrogen role on bone is also mediated by RANKL and OPG. In postmenopausal women who have estrogen deficiency, it increases the rate of RANKL, which increases osteoclastogenesis. Obese individuals who have a high level of leptin will be effected by bone protection. There are similarities in the mechanism between estrogen and leptin in influencing the process of bone remodeling. It may be considered that the role of estrogen can be replaced by leptin. Molecular genetic aspects that play a role in bone remodeling, such as leptin, leptin receptors, cytokines (e.g. RANK, RANKL, and OPG), require further study to be useful, especially regarding osteoporosis therapy based on genetic analysis.

This study examines the differences in bone mineral density between normal-weight children and children with overweight or obesity. A systematic review and meta-analysis of observational studies (published up to 22 June 2016) on the differences in bone mineral density between normal-weight children and overweight and obese children was performed. Results were pooled when possible and mean differences (MDs) were calculated between normal-weight and overweight and normal-weight and obese children for bone content and density measures at different body sites. Twenty-seven studies, with a total of 5,958 children, were included. There was moderate and high quality of evidence that overweight (MD 213 g; 95% confidence interval [CI] 166, 261) and obese children (MD 329 g; 95%CI [229, 430]) have a significantly higher whole body bone mineral content than normal-weight children. Similar results were found for whole body bone mineral density. Sensitivity analysis showed that the association was stronger in girls. Overweight and obese children have a significantly higher bone mineral density compared with normal-weight children. Because there was only one study included with a longitudinal design, the long-term impact of childhood overweight and obesity on bone health at adulthood is not clear. © 2017 World Obesity Federation.

A paucity of data exists concerning the normal glycemic profile in nondiabetic pregnancies. Using a novel approach that provides continuous measurement of blood glucose, we sought to evaluate the ambulatory daily glycemic profile in the second half of pregnancy in nondiabetic women. Fifty-seven obese and normal weight nondiabetic subjects were evaluated for 72 consecutive hours with continuous glucose monitoring by measurement interstitial glucose levels in subcutaneous tissue every 5 minutes. Subjects were instructed not to modify their lifestyle or to follow any dietary restriction. For each woman, mean and fasting blood glucose values were determined; for each meal during the study period, the first 180 minutes were analyzed. For the study group, the fasting blood glucose level was 75 +/- 12 mg/dL; the mean blood glucose level was 83.7 +/- 18 mg/dL; the postprandial peak glucose value level was 110 +/- 16 mg/dL, and the time interval that was needed to reach peak postprandial glucose level was 70 +/- 13 minutes. A similar postprandial glycemic profile was obtained for breakfast, lunch, and dinner. Obese women were characterized by a significantly higher postprandial glucose peak value, increased 1- and 2-hour postprandial glucose levels, increased time interval for glucose peak, and significantly lower mean blood glucose during the night. No difference was found in fasting and mean blood glucose between obese and nonobese subjects. Glycemic profile characterization in both obese and normal weight nondiabetic subjects provide a measure for the desired level of glycemic control in pregnancy that is complicated with diabetes mellitus.

Both menopausal period and aging have influence on body composition, increase of total body fat and visceral fat in particular. We should be aware that changes in body composition, mainly fat translocation to abdominal region, can occur without significant changes in body weight. Therefore quantitative abdominal fat assessment should be our aim. Body composition analysis based on two compartment model and abdominal fat area assessment in cross section. Subjects in postmenopausal period (41 women) were recruited for this study and divided into 2 groups: group 1 - women aged 45-56 years and group 2 - women aged 57-79 years. Body composition analysis and abdominal fat area assessment were conducted by using bioelectrical impedance method with BioScan 920 (Maltron int.) accordingly with standardized procedure. Women in early postmenopausal stage (Group 1) had statistically significant lower total body fat percentage in comparison with women in late postmenopausal period (Group 2) (41.09 ± 7.72% vs. 50.7 ± 9.88%, p=0.0021). Also women in group 1 were characterized by significant lower visceral fat area (VAT) as well as subcutaneous fat area (SAT) in comparison with group 2 (respectively VAT 119.25 ± 30.09 cm2 vs. 199.36 ± 87.38 cm2, p=0.0011; SAT 175.19 ±57.67 cm2 vs. 223.4±74.29 cm2, p=0.0336). According to VAT criteria (>120 cm2), 44% of women in group 1 and 80% in group 2 had excess of visceral fat. Both total body fat and intra-abdominal fat increased with age, independently of weight changes.

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

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

Full Text Available BackgroundThe objective of the current study was to determine whether there was an association between urinary albumin excretion and cardiovascular disease (CVD risk by estimating the Framingham Risk Score (FRS in postmenopausal women without diabetes.MethodsThis study was based on data from the Korea National Health and Nutrition Examination Survey, which was conducted by the Korean Ministry of Health and Welfare in 2011 to 2013. Data on 2,316 postmenopausal women from a total of 24,594 participants was included in the analysis.ResultsThe mean FRS was significantly different in each of the urinary albumin to creatinine ratio (UACR subgroups, and it increased with UACR. The FRS was 12.69±0.12 in the optimal group, 14.30±0.19 in the intermediate normal group, 14.62±0.26 in the high normal group, and 15.86±0.36 in the microalbuminuria group. After fully adjusting for potential confounding factors, high normal levels and microalbuminuria were significantly associated with the highest tertile of FRS ([odds ratio (OR, 1.642; 95% confidence interval (CI, 1.124 to 2.400] and [OR, 3.385; 95% CI, 2.088 to 5.488], respectively compared with the optimal subgroup. High normal levels and microalbuminuria were also significantly associated with a ≥10% 10-year risk of CVD ([OR, 1.853; 95% CI, 1.122 to 3.060] and [OR, 2.831; 95% CI, 1.327 to 6.037], respectively after adjusting for potential confounding covariates.ConclusionUrinary albumin excretion reflects CVD risk in postmenopausal women without diabetes, and high normal levels and microalbuminuria were independently associated with a higher risk of CVD.

To provide an in-depth analysis of the relationship between obesity and fast-food consumption by comparing urban obese and normal-weight Saudi Arabian children. A multicentre cross-sectional study was conducted from December 2015 to March 2016. Participants were divided into two groups (normal weight and obese) and further stratified by sex. Groups were randomly selected using a multistage stratified cluster-sampling technique. A self-paced questionnaire was used to collect data relating to food consumption. Weight height and waist circumference were measured and bioelectrical impedance analysis was performed in all children. Capital of Saudi Arabia, Riyadh. Children aged 9·00-11·99 years (n 1023). Compared with normal-weight groups, intake frequency of fast food/week was higher among the obese groups (Pfast-food consumption outside (Pfast-food meals together was a protective factor against obesity (OR; 95 % CI: 2·67; 1·44, 4·96, Pfast foods (P=0·021), child-friendly menu (P=0·020) and meal cost (Pfast-food restaurants; these data were replicated for parents with obese boys, but not girls. Development of effective interventions to reduce fast-food consumption in Saudi Arabian schoolchildren requires greater research-based evidence of fast-food consumption habits and practices associated with increased childhood obesity.

The adverse effects of obesity on the physical health have been extensively studied in the general population, but not in motorcycle riders (includes both drivers and pillions). The aim of this study was to compare injury patterns, injury severities, mortality rates, and in-hospital or intensive care unit (ICU) length of stay (LOS) between obese and normal-weight patients who were hospitalized for the treatment of trauma following motorcycle accidents in a level I trauma center. Detailed data of 466 obese adult patients with a body mass index (BMI) ≥30 kg/m(2) and 2701 normal-weight patients (25 > BMI ≥18.5 kg/m(2)) who had sustained motorcycle accident-related injuries were retrieved from the Trauma Registry System between January 1, 2009 and December 31, 2013. We used the Pearson's chi-squared test, Fisher's exact test, and independent Student's t-test to analyze differences between the two groups. Compared to normal-weight motorcycle riders, more obese riders were men and drivers as opposed to pillions. In addition, fewer obese motorcycle riders showed alcohol intoxication. Analyses of the patients' Abbreviated Injury Scale (AIS) scores revealed that obese motorcycle riders presented with a higher rate of injury to the thorax, but a lower rate of injury to the face than normal-weight patients. In addition, obese motorcycle riders had a 2.7-fold greater incidence of humeral, 1.9-fold greater incidence of pelvic, and 1.5-fold greater incidence of rib fractures. In contrast, normal-weight motorcycle riders sustained a significantly higher rate of maxillary and clavicle fractures. Obese motorcycle riders had a significant longer in-hospital LOS than normal-weight motorcycle riders did (10.6 days vs. 9.5 days, respectively; p = 0.044), with an increase in in-hospital LOS of 0.82 days associated with every 10-unit increase in BMI. No statistically significant differences in Injury Severity Score (ISS), New Injury Severity Score (NISS), Trauma

Comparison of Mechanical Properties of Lightweight and Normal Weight Concretes Reinforced with Steel Fibers

Full Text Available Compared to conventional concrete, lightweight concrete is more brittle in nature however, in many situations its application is advantageous due to its lower weight. The associated brittleness issue can be, to some extent, addressed by incorporation of discrete fibers. It is now established that fibers modify some fresh and hardened concrete properties. However, evaluation of those properties for lightweight fiber-reinforced concrete (LWFC against conventional/normal weight concrete of similar strength class has not been done before. Current study not only discusses the change in these properties for lightweight concrete after the addition of steel fibers, but also presents a comparison of these properties with conventional concrete with and without fibers. Both the lightweight and conventional concrete were reinforced with similar types and quantity of fibers. Hooked end steel fibers were added in the quantities of 0, 20, 40 and 60kg/m3. For similar compressive strength class, results indicate that compared to normal weight fiber-reinforced concrete (NWFC, lightweight fiber-reinforced concrete (LWFC has better fresh concrete properties, but performs poorly when tested for hardened concrete properties.

Menopause is associated with significant hormonal changes that result in increased total body fat and abdominal fat, amplifying the risk for metabolic syndrome and diseases such as diabetes, cardiovascular disease and cancer in postmenopausal women. Intermittent fasting regimens hold significant health benefit promise for obese humans, however, regimens that include extreme daytime calorie restriction or daytime fasting are generally associated with hunger and irritability, hampering long-term compliance and adoption in the clinical setting. Time-restricted feeding (TRF), a regimen allowing eating only during a specific period in the normal circadian feeding cycle, without calorie restriction, may increase compliance and provide a more clinically viable method for reducing the detrimental metabolic consequences associated with obesity. We tested TRF as an intervention in a mouse model of postmenopausal obesity. Metabolic parameters were measured using Clinical Laboratory Animal Monitoring System (CLAMS) and we carried out glucose tolerance tests. We also stained liver sections with oil red O to examine steatosis and measured gene expression related to gluconeogenesis. Preexisting metabolic disease was significantly attenuated during 7 weeks of TRF. Despite having access to the same high fat diet (HFD) as ad libitum fed (ALF) mice, TRF mice experienced rapid weight loss followed by a delayed improvement in insulin resistance and a reduced severity of hepatic steatosis by having access to the HFD for only 8h during their normal nocturnal feeding period. The lower respiratory exchange ratio in the TRF group compared with the ALF group early in the dark phase suggested that fat was the predominant fuel source in the TRF group and correlated with gene expression analyses that suggested a switch from gluconeogenesis to ketogenesis. In addition, TRF mice were more physically active than ALF fed mice. Our data support further analysis of TRF as a clinically viable form of

Background: Sensory properties of foods promote and guide consumption in hunger states, whereas satiation should dampen the sensory activation of ingestive behaviors. Such activation may be disordered in obese individuals. Objective: Using functional magnetic resonance imaging (fMRI), we studied regional brain responses to food odor stimulation in the sated state in obese and normal-weight individuals targeting ventral frontal regions known to be involved in coding for stimulus reward value. Design: Forty-eight women (25 normal weight; 23 obese) participated in a 2-day (fed compared with fasting) fMRI study while smelling odors of 2 foods and an inedible, nonfood object. Analyses were conducted to permit an examination of both general and sensory-specific satiation (satiation effects specific to a given food). Results: Normal-weight subjects showed significant blood oxygen level–dependent responses in the ventromedial prefrontal cortex (vmPFC) to food aromas compared with responses induced by the odor of an inedible object. Normal-weight subjects also showed general (but not sensory-specific) satiation effects in both the vmPFC and orbitofrontal cortex. Obese subjects showed no differential response to the aromas of food and the inedible object when fasting. Within- and between-group differences in satiation were driven largely by changes in the response to the odor of the inedible stimulus. Responses to food aromas in the obese correlated with trait negative urgency, the tendency toward negative affect-provoked impulsivity. Conclusions: Ventral frontal signaling of reward value may be disordered in obesity, with negative urgency heightening responses to food aromas. The observed nature of responses to food and nonfood stimuli suggests that future research should independently quantify each to fully understand brain reward signaling in obesity. This trial was registered at clinicaltrials.gov as NCT02041039. PMID:24695888

Objective: To explore the association between postmenopausal hormone therapy (HT) and Alzheimer disease (AD). Methods: Twenty-year follow-up data from the Kuopio Osteoporosis Risk Factor and Prevention study cohort were used. Self-administered questionnaires were sent to all women aged 47–56 years, residing in Kuopio Province starting in 1989 until 2009, every 5th year. Register-based information on HT prescriptions was available since 1995. Probable AD cases, based on DSM-IV and National Institute of Neurological and Communicative Disorders and Stroke–Alzheimer's Disease and Related Disorders Association criteria, were identified from the special reimbursement register (1999–2009). The study population included 8,195 women (227 cases of incident AD). Results: Postmenopausal estrogen use was not associated with AD risk in register-based or self-reported data (hazard ratio/95% confidence interval 0.92/0.68–1.2, 0.99/0.75–1.3, respectively). Long-term self-reported postmenopausal HT was associated with reduced AD risk (0.53/0.31–0.91). Similar results were obtained with any dementia diagnosis in the hospital discharge register as an outcome. Conclusions: Our results do not provide strong evidence for a protective association between postmenopausal HT use and AD or dementia, although we observed a reduced AD risk among those with long-term self-reported HT use.

Full Text Available Abstract Background Obesity has long been associated with postmenopausal breast cancer risk and more recently with premenopausal breast cancer risk. We previously observed that nipple aspirate fluid (n levels of prostate specific antigen (PSA were associated with obesity. Serum (s levels of adiponectin are lower in women with higher body mass index (BMI and with breast cancer. We conducted a prospective study of obese women who underwent gastric bypass surgery to determine: 1 change in n- and s-adiponectin and nPSA after surgery and 2 if biomarker change is related to change in BMI. Samples (30-s, 28-n and BMI were obtained from women 0, 3, 6 and 12 months after surgery. Findings There was a significant increase after surgery in pre- but not postmenopausal women at all time points in s-adiponectin and at 3 and 6 months in n-adiponectin. Low n-PSA and high s-adiponectin values were highly correlated with decrease in BMI from baseline. Conclusions Adiponectin increases locally in the breast and systemically in premenopausal women after gastric bypass. s-adiponectin in pre- and nPSA in postmenopausal women correlated with greater weight loss. This study provides preliminary evidence for biologic markers to predict weight loss after gastric bypass surgery.

A growing system with weighted and multiplicatively interacting particles is investigated. Each particle has a quantity that changes multiplicatively after a binary interaction, with its growth rate controlled by a weight parameter in a homogeneous symmetric kernel. We consider the system using moment inequalities and analytically derive the log-normal-type tail in the probability distribution function of quantities when the parameter is negative, which is different from the result for single-body multiplicative processes. We also find that the system approaches a winner-take-all state when the parameter is positive.

Fat mass localization affects lipid metabolism differently at rest and during exercise in overweight and normal-weight subjects. The aim of this study was to investigate the impact of a low vs high ratio of abdominal to lower-body fat mass (index of adipose tissue distribution) on the exercise intensity (Lipox(max)) that elicits the maximum lipid oxidation rate in normal-weight women. Twenty-one normal-weight women (22.0 ± 0.6 years, 22.3 ± 0.1 kg.m(-2)) were separated into two groups of either a low or high abdominal to lower-body fat mass ratio [L-A/LB (n = 11) or H-A/LB (n = 10), respectively]. Lipox(max) and maximum lipid oxidation rate (MLOR) were determined during a submaximum incremental exercise test. Abdominal and lower-body fat mass were determined from DXA scans. The two groups did not differ in aerobic fitness, total fat mass, or total and localized fat-free mass. Lipox(max) and MLOR were significantly lower in H-A/LB vs L-A/LB women (43 ± 3% VO(2max) vs 54 ± 4% VO(2max), and 4.8 ± 0.6 mg min(-1)kg FFM(-1)vs 8.4 ± 0.9 mg min(-1)kg FFM(-1), respectively; P normal-weight women, a predominantly abdominal fat mass distribution compared with a predominantly peripheral fat mass distribution is associated with a lower capacity to maximize lipid oxidation during exercise, as evidenced by their lower Lipox(max) and MLOR.

Ghrelin induces obesity via central and peripheral mechanisms. Administration of ghrelin leads to increased food intake and decreased fat utilisation in rodents. Ghrelin levels are decreased in obese individuals. Recently, a polymorphism (Arg-51-Gln) within the ghrelin gene (GHRL) was described to be associated with obesity. We screened the GHRL coding region in 215 extremely obese German Children and adolescents (study group 1) and 93 normal weight students (study group 2) by single strand conformation polymorphism analysis (SSCP). We found the two previously described single nucleotide polymorphisms (SNP: Arg-51-Gln and Leu-72-Met) in similar frequencies in study groups 1 and 2 (allele frequencies were: 0.019 and 0.016 for the 51-Gln allele and 0.091 and 0.086 for the 72-Met allele, respectively). Hence, we could not confirm the previous finding. Additionally, two novel variants were identified within the coding region: (1) We detected one healthy normal weight individual with a frameshift mutation (2bp deletion at codon 34). This frameshift mutation affects the coding region of the mature ghrelin. Hence, it is highly likely that the normal weight student is haplo-insufficient for ghrelin. (2) An A to T transversion leads to an amino acid exchange from Gln to Leu at amino acid position 90. The frequency of the 90-Leu allele was significantly higher in the extremely obese children and adolescents (0.063) than in the normal weight students (0.016; nominal p = 0.011). Additionally, we genotyped 134 underweight students and 44 normal weight adults for this SNP. Genotype frequencies were similar in extremely obese children and adolescents, underweight students and normal weight adults (p > 0.8). In conclusion, we identified four sequence variants in the coding region of the ghrelin gene in individuals belonging to different weight extremes. A frameshift mutation was detected in a normal weight individual. None of the variants seem to influence weight regulation.

Obesity is associated with tumor promoting pathways related to insulin resistance and chronic low-grade inflammation which have been linked to various disease states, including cancer. Many studies have focused on the relationship between obesity and increased estrogen production, which contributes to the pathogenesis of estrogen receptor-positive breast cancers. The link between obesity and other breast cancer subtypes, such as triple-negative breast cancer (TNBC) and Her2/neu+ (Her2+) breast cancer, is less clear. We hypothesize that obesity may be associated with the pathogenesis of specific breast cancer subtypes resulting in a different subtype distribution than normal weight women. A single-institution, retrospective analysis of tumor characteristics of 848 patients diagnosed with primary operable breast cancer between 2000 and 2013 was performed to evaluate the association between BMI and clinical outcome. Patients were grouped based on their BMI at time of diagnosis stratified into three subgroups: normal weight (BMI = 18-24.9), overweight (BMI = 25-29.9), and obese (BMI > 30). The distribution of breast cancer subtypes across the three BMI subgroups was compared. Obese and overweight women were more likely to present with TNBC and normal weight women with Her2+ breast cancer (p = 0.008). We demonstrated, for the first time, that breast cancer subtype distribution varied significantly according to BMI status. Our results suggested that obesity might activate molecular pathways other than the well-known obesity/estrogen circuit in the pathogenesis of breast cancer. Future studies are needed to understand the molecular mechanisms that drive the variation in subtype distribution across BMI subgroups.

Metabolic Rather Than Body Composition Measurements Are Associated With Lower Serum Natriuretic Peptide Concentrations in Normal Weight and Obese Men

BACKGROUND: Several studies have shown that obese persons have lower circulating natriuretic peptide (NP) concentrations. The cause of the relative NP deficiency seen in obese persons is poorly understood, although variation in body composition and metabolic abnormalities has been suggested to play...... a role. Thus, the aim of this study was to assess whether variation in circulating NP concentrations would be associated with differences in metabolic disturbances rather than with differences in body composition. METHODS: In 27 normal weight men (body mass index (BMI) = 20.0-24.9kg/m(2)) and 103 obese...... weight ± SD was 74.9±6.7kg in the normal weight men and 106.1±10.8kg in obese men. Applying multiple regressions, adjusting for age and weight status (normal weight vs. obese), serum MR-proANP concentrations were significantly inversely associated with serum insulin concentrations (β = -0.39; P

Expression-robust 3D face recognition via weighted sparse representation of multi-scale and multi-component local normal patterns

KAUST Repository

Li, Huibin

2014-06-01

In the theory of differential geometry, surface normal, as a first order surface differential quantity, determines the orientation of a surface at each point and contains informative local surface shape information. To fully exploit this kind of information for 3D face recognition (FR), this paper proposes a novel highly discriminative facial shape descriptor, namely multi-scale and multi-component local normal patterns (MSMC-LNP). Given a normalized facial range image, three components of normal vectors are first estimated, leading to three normal component images. Then, each normal component image is encoded locally to local normal patterns (LNP) on different scales. To utilize spatial information of facial shape, each normal component image is divided into several patches, and their LNP histograms are computed and concatenated according to the facial configuration. Finally, each original facial surface is represented by a set of LNP histograms including both global and local cues. Moreover, to make the proposed solution robust to the variations of facial expressions, we propose to learn the weight of each local patch on a given encoding scale and normal component image. Based on the learned weights and the weighted LNP histograms, we formulate a weighted sparse representation-based classifier (W-SRC). In contrast to the overwhelming majority of 3D FR approaches which were only benchmarked on the FRGC v2.0 database, we carried out extensive experiments on the FRGC v2.0, Bosphorus, BU-3DFE and 3D-TEC databases, thus including 3D face data captured in different scenarios through various sensors and depicting in particular different challenges with respect to facial expressions. The experimental results show that the proposed approach consistently achieves competitive rank-one recognition rates on these databases despite their heterogeneous nature, and thereby demonstrates its effectiveness and its generalizability. © 2014 Elsevier B.V.

Insulin resistance (IR) may develop very early in life being associated with occurrence of cardiometabolic risk factors (CMRFs). Aim of the present study was to identify in young Caucasians normative values of IR as estimated by the homeostasis model assessment (HOMA-IR) and cutoffs diagnostic of CMRFs. Anthropometrics and biochemical parameters were assessed in 2753 Caucasians (age 2-17.8 years; 1204 F). Reference ranges of HOMA-IR were defined for the whole population and for samples of normal-weight and overweight/obese individuals. The receiver operator characteristic analysis was used to find cutoffs of HOMA-IR accurately identifying individuals with any CMRF among total cholesterol and/or triglycerides higher than the 95th percentile and/or HDL cholesterol lower than the 5th for age and sex, impaired glucose tolerance, and alanine aminotransferase levels ≥40 U/l. Overweight/obese individuals had higher HOMA-IR levels compared with normal-weight peers (p HOMA-IR index rose progressively with age, plateaued between age 13 and 15 years and started decreasing afterward. HOMA-IR peaked at age 13 years in girls and at 15 years in boys. The 75th percentile of HOMA-IR in the whole population (3.02; AUROC = 0.73, 95 % CI = 0.70-0.75), in normal-weight (1.68; AUROC = 0.76, 95 % CI = 0.74-0.79), and obese (3.42; AUROC = 0.71, 95 % CI = 0.69-0.72) individuals identified the cutoffs best classifying individuals with any CMRF. Percentiles of HOMA-IR varied significantly in young Caucasians depending on sex, age, and BMI category. The 75th percentile may represent an accurate cutoff point to suspect the occurrence of one or more CMRFs among high total cholesterol and triglycerides, low HDL cholesterol, and ALT ≥ 40 UI/l.

Background: Weight loss may improve glucose control in persons with type 2 diabetes. The effects of fat quality, as opposed to quantity, on weight loss are not well understood. Objective: We compared the effects of 2 dietary oils, conjugated linoleic acid (CLA) and safflower oil (SAF), on body weight and composition in obese postmenopausal women with type 2 diabetes. Design: This was a 36-wk randomized, double-masked, crossover study. Fifty-five obese postmenopausal women with type 2 diabetes received SAF or CLA (8 g oil/d) during two 16-wk diet periods separated by a 4-wk washout period. Subjects met monthly with the study coordinator to receive new supplements and for assessment of energy balance, biochemical endpoints, or anthropometric variables. Results: Thirty-five women completed the 36-wk intervention. Supplementation with CLA reduced body mass index (BMI) (P = 0.0022) and total adipose mass (P = 0.0187) without altering lean mass. The effect of CLA in lowering BMI was detected during the last 8 wk of each 16-wk diet period. In contrast, SAF had no effect on BMI or total adipose mass but reduced trunk adipose mass (P = 0.0422) and increased lean mass (P = 0.0432). SAF also significantly lowered fasting glucose (P = 0.0343) and increased adiponectin (P = 0.0051). No differences were observed in dietary energy intake, total fat intake, and fat quality in either diet period for either intervention. Conclusions: Supplementation with CLA and SAF exerted different effects on BMI, total and trunk adipose mass, and lean tissue mass in obese postmenopausal women with type 2 diabetes. Supplementation with these dietary oils may be beneficial for weight loss, glycemic control, or both. PMID:19535429

The compliance of large elastic arteries in the cardiothoracic region decreases with advancing age/menopause and plays an important role in the increased prevalence of cardiovascular diseases in postmenopausal women. We determined whether oxidative stress contributes to the reduced large elastic artery compliance of postmenopausal women. Carotid artery compliance was measured during acute intravenous infusions of saline (baseline control) and supraphysiological doses of the potent antioxidant ascorbic acid in premenopausal (n=10; 23+/-1; mean+/-SE) and estrogen-deficient postmenopausal (n=21; 55+/-1 years) healthy sedentary women. Carotid artery compliance was 56% lower in postmenopausal compared with premenopausal women during baseline control (PAscorbic acid infusion increased carotid artery compliance by 26% in postmenopausal women (1.11+/-0.07 to 1.38+/-0.08 mm2/mm Hgx10(-1); Pascorbic acid. In the pooled population, the change in arterial compliance with ascorbic acid correlated with baseline waist-to-hip ratio (r=0.56; P=0.001), plasma norepinephrine (r=0.58; P=0.001), and LDL cholesterol (r=0.54; P=0.001). These results suggest that oxidative stress may be an important mechanism contributing to the reduced large elastic artery compliance of sedentary, estrogen-deficient postmenopausal women. Increased abdominal fat storage, sympathetic nervous system activity, and LDL cholesterol may be mechanistically involved in oxidative stress-associated suppression of arterial compliance in postmenopausal women.

Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association. Methods This is a retrospective cross-sectional study of 62,351 singleton pregnancies from the National Collaborative Perinatal Neonatal Network between 2001 and 2009 from 27 hospitals across Lebanon. Women who had underweight and normal pre-pregnancy BMI were included. Results A total of 8.6% newborns were SGA and 6.6% of women were underweight. Among women with normal and underweight pre-pregnancy BMI, 8.6 and 12.4% had SGA births respectively. Overall, the adjusted OR of having SGA newborns was significantly higher among underweight women (OR = 1.448; 95%CI = 1.287-1.630) compared to normal pre-pregnancy BMI. Below normal weight gain significantly increased the odds of SGA for both normal and underweight pre-pregnancy BMI women, with adjusted ORs of 1.535 (95% CI = 1.418-1.661) and 1.970 (95%CI = 1.515-2.560) respectively. Discussion Higher risks of SGA newborns in underweight and normal BMI women with low GWG were observed. In addition, normal weight gain couldn't protect underweight women of having risk for SGA newborns. Hence, all pregnant women should be encouraged to maintain healthy BMI before pregnancy and attain adequate GWG.

To assess the effect of a lifestyle intervention in lowering/normalizing blood pressure (BP) levels in hypertensive (controlled or not) obese patients. In this prospective observational study, 490 obese hypertensive patients, 389 controlled (BP < 140/90 mm Hg; CH) and 101 uncontrolled (BP ≥ 140/90 mm Hg; UH) attended a 3-month lifestyle intervention. Before and after the intervention we assessed weight, waist circumference, fat mass, BP, metabolic and renal variables, and physical activity. A multivariate regression model was used to determine the predictors of BP changes. 18.9% of CH and 20.0% of UH were on ≥ 3 antihypertensive drugs. Weight change (average -4.9 ± 2.7%) was independent of the antihypertensive drugs employed. Systolic BP (SBP) decreased by 23 mm Hg and diastolic BP (DBP) by 9 mm Hg, in patients with UH most of whom (89%) normalized BP levels (in 49% after a weight loss < 5%). Age, gender, whole and central obesity, concomitance of type 2 diabetes, chronic renal disease, physical activity intensification, and pharmacological therapy did not affect BP lowering. In the regression analysis with SBP change as dependent variable, weight reduction (β = 0.523, p = 0.005) and group (UH vs. CH, β = -19.40, p = 0.0005) remained associated with SBP reduction. When DBP change was entered as dependent variable, baseline uric acid remained associated with DBP reduction (β = 0.824, p < 0.05). Lifestyle interventions are useful for all obese hypertensive patients in most of whom a modest weight loss is sufficient to normalize BP levels avoiding the aggressive use of multiple antihypertensive drugs. © 2016 The Author(s) Published by S.

Full Text Available Background: In this study, we aim to compare insulin and leptin levels in adolescents with or without excess weight and in those with or without abdominal obesity. Materials and Methods : This case-control study was conducted among 486 samples. We randomly selected 243 overweight and an equal number of normal-weight adolescents from among participants of the third survey of a national surveillance program entitled "Childhood and Adolescence Surveillance and PreventIon of Adult Non-communicable diseases study." Serum insulin and leptin were compared between two groups and their correlation was determined with other variables. Results: The mean age and body mass index (BMI of participants were 14.10 ± 2.82 years and 22.12 ± 6.49 kg/m 2 , respectively. Leptin and insulin levels were higher in overweight than in normal-weight adolescents (P < 0.05. Leptin level was higher in children with abdominal obesity than in their other counterparts (P < 0.001. Leptin level was correlated with age, fasting blood glucose, BMI, and insulin level. Conclusion: Insulin and leptin levels were higher among overweight and obese children, which may reflect insulin and leptin-resistance. Given the complications of excess weight from early life, prevention and controlling childhood obesity should be considered as a health priority.

Full Text Available Background: Postmenopausal osteoporosis affects large fraction of elderly women. Oxidative stress (OS appears to be involved in its pathogenesis. The scarcity of human studies focusing on the correlation between bone mineral density (BMD and OS in postmenopausal women has prompted us to study on this issue. Materials and Methods: We conducted a cross sectional study in 95 subjects, between 21-65 years of age, including postmenopausal osteoporotic females (n = 35, healthy postmenopausal females (n = 30 and healthy females in reproductive age group (n = 30. We measured serum antioxidant activity of superoxide dismutase (SOD, catalase, glutathione peroxidase (GPx, and total antioxidant power (TAP. BMD was obtained at lumbar spine and femur neck by dual-energy X-ray absorptiometry scan. Osteoporosis was considered when subjects had a BMD of 2.5 standard deviations or more below the mean value for young adults. Results: Serum GPx, SOD, catalase and TAP level were found significantly lower in osteoporotic postmenopausal group as compared to healthy postmenopausal women and women in healthy reproductive age group healthy reproductive women (P 0.005. Conclusion: These findings support that oxidative stress plays an important role in pathogenesis of postmenopausal osteoporosis. We did not find any significant association between BMD and serum level of antioxidants (P > 0.05. The failure to detect this association does not preclude the role of OS in osteoporosis because OS is complex and dynamic process.

The proportion of overweight and obese youths is high. The present study aimed to investigate the development of self-image and its components during a one-year follow-up among non-referred adolescents with excess and normal weight. Furthermore, we separately analyzed the data for girls and boys. Altogether 86 8(th) grades (41 girls and 45 boys) with a relative weight of 26% or more above the median and 91 controls (43 girls and 48 boys) with normal weight participated the follow-up. The Offer Self-Image Questionnaire, Revised (OSIQ-R) was used to assess self-image at baseline and on follow-up. In the OSIQ-R, a low total raw score implies positive adjustment, while a high raw score implies poor adjustment and a negative self-image. The study design was doubly correlated (pairs and time), and a linear mixed model was used in the statistical analysis. In OSIQ-R total scores, a comparative improvement was observed in girls with normal weight. Among these girls, significant change scores compared to zero were seen in impulse control, social functioning, vocational attitudes, self-confidence, self-reliance, body image, sexuality, and ethical values. In girls with excess weight, none of the change scores compared to zero were statistically significant. When the girls with normal and excess weight were compared, the difference in change scores was largest in sexuality and vocational attitudes. Change scores compared to zero were significant in sexuality and idealism for boys with excess weight, and in impulse control, mental health, self-reliance, and sexuality for normal weight boys. When the boys with excess and normal weight were compared, no statistically significant differences emerged in change scores. In mid-adolescent girls, the influence of overweight and obesity on the development of self-image is substantial. Weight management programs directed at overweight adolescent girls should include psychological interventions aiming to diminish self-image distress

Psychological symptoms are common & bothersome in post menopausal women. Hence, screening these women for risk factors for psychological disorders is an important measure to improve their health. To study the risk assessment for psychological disorders in postmenopausal women Material & Methods: This was a prospective and observational study conducted in the Department of Obstetrics and Gynecology of a North Indian tertiary care hospital. It included a cross-section of 200 postmenopausal women attending gynecology OPD and menopausal clinic. Psychological symptoms were present in 32% postmenopausal women while sleep disturbance and decreased concentration were reported by nearly 34%. Irritability, nervousness and depression were the presenting complaints in 31.5%, 28.5% and 23.5% women respectively. Mild depression was present in 41.5%, whereas 3% women suffered from clinical (moderate to severe) depression. Depression was significantly associated with vasomotor symptoms (p=0.000), past history of depression (p=0.048) and psychosocial stressors (p=0.000). Women during postmenopausal years are at increased risk of psychological disorders; hence assessment of mental health and address of related issues should be an integral part of comprehensive evaluation of these women.

The association between gut microbiota and circulating zonulin level, a marker of intestinal permeability, has not been studied yet. The aim of the study is the assessment of plasma zonulin, haptoglobin and proinflammatory cytokines (TNF- α and IL-6) levels in relation to composition of gut microbiota in obese and normal weight subjects. Circulating inflammation markers, such as TNF- α , sTNFR1, sTNFR2, IL-6, zonulin, and haptoglobin levels were measured and semiquantitative analysis of gut microbiota composition was carried out in 50 obese and 30 normal weight subjects without concomitant diseases. Higher circulating zonulin, TNF- α , sTNFR1, sTNFR2, and IL-6 levels were found in the obese subjects. Plasma zonulin level correlated positively with age (r = 0.43, P zonulin (r = 0.26, P zonulin level was proportional to daily energy intake (r = 0.27, P zonulin level, a potential marker of interstitial permeability.

The longitudinal trajectories of body composition of children born to mothers with normal weight, overweight, and obesity have not been evaluated using precise body composition methods. This study investigated the relationship between maternal prepregnancy BMI and offspring body composition trajectories during the first 6 years of life. Healthy infants (N = 325) were assessed longitudinally (at ages 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, and 6 years) using dual-energy X-ray absorptiometry. Mixed-effects regression for repeated measures was used to model each continuous outcome as a function of maternal BMI and covariates (race, gestational age, birth weight, and mode of infant feeding). Maternal obesity differentially impacted body fat, but not bone mineral content or density, of girls and boys. Boys born to mothers with obesity have higher body fat from ages 2-6 years compared to boys born to normal-weight and overweight mothers (P obesity was not different across groups during the first 6 years of life (P > 0.05). This clinical observational study demonstrates a sexual dimorphism in offspring body composition until age 6 years based on maternal BMI, with a greater effect of maternal adiposity seen in boys than in girls. © 2015 The Obesity Society.

Multiple mechanisms are likely to account for the link between obesity and increased risk of postmenopausal breast cancer. Two adipokines, leptin and adiponectin, are of particular interest due to their opposing biologic functions and associations with breast cancer risk. In the current study, we investigated the effects of leptin and adiponectin on normal breast epithelial stem cells. Levels of leptin in human adipose explant-derived conditioned media positively correlated with the size of the normal breast stem cell pool. In contrast, an inverse relationship was found for adiponectin. Moreover, a strong linear relationship was observed between the leptin/adiponectin ratio in adipose conditioned media and breast stem cell self-renewal. Consistent with these findings, exogenous leptin stimulated whereas adiponectin suppressed breast stem cell self-renewal. In addition to local in-breast effects, circulating factors, including leptin and adiponectin, may contribute to the link between obesity and breast cancer. Increased levels of leptin and reduced amounts of adiponectin were found in serum from obese compared with age-matched lean postmenopausal women. Interestingly, serum from obese women increased stem cell self-renewal by 30% compared with only 7% for lean control serum. Taken together, these data suggest a plausible explanation for the obesity-driven increase in postmenopausal breast cancer risk. Leptin and adiponectin may function as both endocrine and paracrine/juxtacrine factors to modulate the size of the normal stem cell pool. Interventions that disrupt this axis and thereby normalize breast stem cell self-renewal could reduce the risk of breast cancer. ©2015 American Association for Cancer Research.

Obesity has a protective effect against osteoporosis and this effect has been attributed to a high body fat content. It has been shown that the leptin concentration is higher in obese patients. Leptin, the protein product of obesity gene, is a hormone produced in adipose tissue. Some studies suggest that endogenous leptin might influence bone metabolism in postmenopausal women. In this study, we investigated plasma leptin concentrations in postmenopausal women with osteoporosis and also analyzed the relationship between plasma leptin levels and bone mineral density (BMD) in order to understand the potential role of leptin in maintaining bone mass. Forty-two postmenopausal women with osteoporosis and thirty seven age and BMI-matched healthy postmenopausal women were included in the study. The mean femoral neck BMD value in the patient group was significantly lower than that in the control group (0.691±0.1 g/cm2 and 0.863±0.1 g/cm2, respectively; p0.05). Plasma leptin levels were correlated with BMI in both groups (p<0.001 in the patient group and p=0.001 in controls). There was also a strong positive correlation between plasma leptin levels and %fat in both groups (p<0.001 in the patient group and p<0.001 in controls). But there was no correlation between plasma leptin levels and femoral neck BMD values in both groups. Our results do not support the hypothesis that leptin itself plays an important role in maintaining bone mass in postmenopausal women.

The purpose of the present paper was to assess dietary energy reporting as a function of sex and weight status among Ontario and Alberta adolescents, using the ratio of energy intake (EI) to estimated BMR (BMRest). Data were collected using the FBQ, a validated web-based dietary assessment tool (including a 24 h dietary recall, FFQ, and food and physical activity behavioural questions). BMI was calculated from self-reported height and weight and participants were classified as normal weight, overweight or obese. BMR was calculated using the WHO equations (based on weight). Reporting status was identified using the ratio EI:BMRest. Data were collected in public, Catholic and private schools in Ontario and Alberta, Canada. A total of 1917 (n 876 male and n 1041 female) students (n 934 grade 9 and n 984 grade 10) participated. The mean EI:BMRest ratio across all participants was 1.4 (sd 0.6), providing evidence of under-reporting for the total sample. Females under-reported more than males (t = 6.27, P < 0.001), and under-reporting increased with increasing weight status for both males (F = 33.21, P < 0.001) and females (F = 14.28, P < 0.001). After removing those who reported eating less to lose weight, the EI:BMRest was 1.56 (sd 0.6) for males and 1.4 (sd 0.6) for females. The present study highlights methodological challenges associated with self-reported dietary data. Systematic differences in under-reporting of dietary intake by gender and weight status were observed using a web-based survey, similar to observations made using paper-based 24 h recalls and dietitian interviews.

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

Overeating, weight gain and obesity are considered as a major health problem in Western societies. At present, an impairment of response inhibition and a biased salience attribution to food-associated stimuli are considered as important factors associated with weight gain. However, recent findings suggest that the association between an impaired response inhibition and salience attribution and weight gain might be modulated by other factors. Thus, hunger might cause food-associated cues to be perceived as more salient and rewarding and might be associated with an impairment of response inhibition. However, at present, little is known how hunger interacts with these processes. Thus, the aim of the present study was to investigate whether hunger modulates response inhibition and attention allocation towards food-associated stimuli in normal-weight controls. A go-/nogo task with food-associated and control words and a visual dot-probe task with food-associated and control pictures were administered to 48 normal-weight participants (mean age 24.5 years, range 19-40; mean BMI 21.6, range 18.5-25.4). Hunger was assessed twofold using a self-reported measure of hunger and a measurement of the blood glucose level. Our results indicated that self-reported hunger affected behavioral response inhibition in the go-/nogo task. Thus, hungry participants committed significantly more commission errors when food-associated stimuli served as distractors compared to when control stimuli were the distractors. This effect was not observed in sated participants. In addition, we found that self-reported hunger was associated with a lower number of omission errors in response to food-associated stimuli indicating a higher salience of these stimuli. Low blood glucose level was not associated with an impairment of response inhibition. However, our results indicated that the blood glucose level was associated with an attentional bias towards food-associated cues in the visual dot probe task

Hydrodynamic Cucker-Smale model with normalized communication weights and time delay

2017-07-17

We study a hydrodynamic Cucker-Smale-type model with time delay in communication and information processing, in which agents interact with each other through normalized communication weights. The model consists of a pressureless Euler system with time delayed non-local alignment forces. We resort to its Lagrangian formulation and prove the existence of its global in time classical solutions. Moreover, we derive a sufficient condition for the asymptotic flocking behavior of the solutions. Finally, we show the presence of a critical phenomenon for the Eulerian system posed in the spatially one-dimensional setting.

Gender differences in body composition, physical activity, eating behavior and body image among normal weight adolescents--an evolutionary approach.

Body composition but also physical activity patterns underlie gender typical differences throughout human life. In the present study the body composition of 354 girls and 280 boys ageing between 11 and 18 years originating from Eastern Austria were analyzed using bioelectrical impedance method. Normal weight according to body mass index categories was a strict inclusion criterion. Information regarding physical activity during school and leisure time, daily nutritional habits, subjective body satisfaction and weight control practices were collected by means of a structured and standardized questionnaire. Results of the analyses reveal that--as to be expected--adolescent boys and girls differed significantly in body composition, but also in physical activity patterns. Even normal weight girls exhibited a significantly higher amount of absolute and relative fat mass, whereas normal weight boys showed a significantly higher amount of fat free body mass. Furthermore male adolescents were significantly more physically active than their female counterparts. According to the results of multiple regression analyses physical activity patterns had beside sex an independent influence on body composition parameters during adolescence. In contrast, girls and boys showed only minor differences in nutritional habits and weight control practices. Nutritional habits, body satisfaction and weight control practices were not significantly related to body composition parameters. The observed gender differences in body composition as well as in physical activity patterns are interpreted in an evolutionary sense.

Patients with normal weight obesity (NWO) have a normal body mass index (BMI) but elevated body fat percentage (BF%), thereby increasing their risk of cardiovascular and metabolic disorders. The purpose of this research was to determine the prevalence of NWO and its associated factors in a sample of young adults in Trinidad and Tobago (T&T). A cross sectional study involving a convenience non-voluntary sample of participants with a normal BMI of 18.5-24.9 kg/m2 was conducted. The following information was collected: history, basic anthropometric measurements, including BF% via the Tanita Ironman Body Composition Analyzer (BC554), physical examination and basic blood investigations. Participants were divided into two groups; normal BF% (young adult population was found to have NWO. Long-term studies are recommended to study the full implications of these findings.

Adolescence is a critical time of life to accumulate bone for peak bone mass. Factors that may interfere with bone mass accrual during this period may increase the risk of osteoporosis. Several studies have reported that pregnancy during adolescence has detrimental effects on bone mass measurements after pregnancy. However, less is known about how adolescent pregnancy affects bone mineral density (BMD) and osteoporosis after menopause. The aim of this study was to evaluate the association between adolescent pregnancy and osteoporosis in postmenopausal Korean women. We conducted a cross-sectional study of 719 postmenopausal women, all of whom were enrolled in the Korean National Health and Nutrition Examination Survey in 2008. BMD was measured using dual-energy x-ray absorptiometry. Postmenopausal women with histories of adolescent pregnancy had lower BMD of the total hip, femoral neck, and lumbar spine than did women without histories of adolescent pregnancy. Multivariate logistic regression analyses revealed that postmenopausal women with history of adolescent pregnancy were at increased risk of osteoporosis (odds ratio, 2.20; 95% CI, 1.12-4.30) compared with women without history of adolescent pregnancy after adjustments for age, body mass index, marital status, education level, household income, alcohol intake, smoking history, exercise, age at menarche, age at menopause, parity, hormone therapy use, intake of energy and calcium, and vitamin D level. Adolescent pregnancy may be a predictor of osteoporosis in postmenopausal women.

Given the current epidemic of childhood obesity, it has become increasingly important to understand the risks and protective factors associated with this disease. Breastfeeding has been identified as a protective factor; however, the mechanism responsible has not been elucidated. One of the current theories analyzes the role of hormones in breast milk, with special emphasis on adiponectin. This study aims to compare adiponectin levels in breast milk of mothers with normal weight with those in breast milk of overweight/obese mothers as well as to correlate these levels with the infant's weight gain. Forty samples of breast milk were analyzed for adiponectin levels using ELISA, 20 from mothers with normal weight and 20 from overweight/obese mothers. Adiponectin levels were lower in breast milk obtained from overweight/obese mothers than in breast milk from mothers with normal weight (p Infantil de México Federico Gómez.

The purpose of the present study was to obtain a cutoff value of liver fat content for the diagnosis of hepatic steatosis by comparing magnetic resonance (MR) spectroscopy results in children and adolescents with normal and excess weight. The study included 420 children and adolescents (91 normal-weight, 99 overweight, and 230 obese) 8-18 years of age. Proton magnetic resonance spectroscopy was performed with a 3T MR system using point resolved spectroscopy sequence with series echo times. The mean absolute mass concentration of liver fat was obtained: 0.5 ± 0.04% in normal-weight boys; 0.5 ± 0.03% in normal-weight girls; 0.9 ± 0.16% in boys with overweight; 1.1 ± 0.24% in girls with overweight; 1.7 ± 0.24% in boys with obesity; and 1.4 ± 0.21% in girls with obesity. The cutoff value of absolute mass concentration of liver fat for hepatic steatosis was found to be 1.5%. Based on this cutoff value, hepatic steatosis was diagnosed in 16% of boys with overweight, 11% of girls with overweight, 32% of boys with obesity, and 27% of girls with obesity. Proton magnetic resonance spectroscopy was successfully applied to obtain the cutoff value of absolute mass concentration of liver fat for the diagnosis of hepatic steatosis in children and adolescents. Children and adolescents with obesity have higher risk of hepatic steatosis than their peers with overweight. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

This study aims to objectively assess the dentition status in South Indian postmenopausal women and compare the dental health of osteoporotic participants with nonosteoporotic individuals. A total of 150 consecutive ambulatory South Indian postmenopausal women (>50 years of age) were assessed for their dental health using an internationally validated scoring system. Bone mineral density (BMD) was assessed using a dual-energy X-ray absorptiometry scanner. About 39% of the participants were found to have osteoporosis and 23% had osteopenia at any site. More than half of them (57%) had poor dental health, and the predominant problems were cavities (43.5%) and loss of teeth (75%). Among 112 women who had tooth loss, the mean tooth loss was 4.8. The mean tooth loss among patients with normal BMD was 1.09 ± 1.2, in osteopenia was 2.1 ± 2, and in osteoporosis was 5.4 ± 2.8 ( P women with osteoporosis had significantly higher number of tooth loss. Tooth loss may thus be used as a surrogate marker to predict osteoporosis.

Full Text Available Objective. To report an unusual case of ovarian Leydig cell hyperplasia resulting in virilization in a postmenopausal woman. Methods. Patient’s medical history and pertinent literature were reviewed. Results. A 64-year-old woman presented with virilization with worsening hirsutism, deepening of her voice, male musculature, and male pattern alopecia. Her pertinent past medical history included type 1 diabetes, hyperlipidemia, and hypertension. Her pertinent past surgical history included hysterectomy due to fibroids. On further work-up, her serum total testosterone was 506 ng/dL (nl range: 2–45 and free testosterone was 40 pg/mL (nl range: 0.1–6.4. After ruling out adrenal causes, the patient underwent an empiric bilateral oophorectomy that showed Leydig cell hyperplasia on pathology. Six weeks postoperatively, serum testosterone was undetectable with significant clinical improvement. Conclusion. Postmenopausal hyperandrogenism can be the result of numerous etiologies ranging from normal physiologic changes to ovarian or rarely adrenal tumors. Our patient was found to have Leydig cell hyperplasia of her ovaries, a rarely reported cause of virilization.

The benefit of estrogen therapy in postmenopausal women is still uncertain. Based upon extensive observational data, it was believed that estrogen was cardioprotective. The relationship between the period of exposure to endogenous estrogens and the risk of cardiovascular disease (CVD) has not been studied in Korean women. To assess associations between reproductive lifespan and CVD by using the Framingham risk score (FRS) in postmenopausal Korean women. This cross-sectional, population-based study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) for the five years 2008-2012,after adjustment for relevant variables using complex sample analysis and data weighting. Among 25,534 women, 1973 women were enrolled, after excluding those 80 years of age (n=6194), those with diabetes, CVD or cancer (n=491), those with unrecorded physical measurements (n=7335), those with menarche age ≤8 years or ≥20 years (n=6194), and premenopausal women (n=3347). The FRS tended to show a significant negative correlation with the reproductive lifespan (preproductive lifespan and FRS (adjusted relative risk [RR] for reproductive years [shortest lifespan group] compared with 28-33 reproductive years [moderate lifespan group], 1.2, p33 reproductive years [longest lifespan group] compared with 28-33 reproductive years [moderate lifespan group], -0.42, p=0.011). A longer reproductive lifespan is associated with a lower estimated risk of CVD in the next 10 years in postmenopausal women. This result suggests that estrogen has a long-term protective effect against CVD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Background: Homocysteine (HCY interferes with collagen cross-linking in bones and stimulates osteoclast activity. The activated osteoclasts secrete cathepsin K (CathK, a cysteine protease, in eminent quantity during bone resorption. Hyperhomocysteinemia may effect bone mineral density (BMD through CathK. We, therefore, examined the relation between HCY and BMD along with CathK, 25-hydroxyvit-D (25[OH]D, intact parathyroid hormone (iPTH, and Vitamin B12. Materials and Methods: We recruited a total of 93 postmenopausal women between the age group of 45–60 years, attending the Endocrinology outpatient department at King George's Medical University, Lucknow. BMD was done by DXA scan using Hologic QDR1000 system. Based on the WHO criteria, patients were segregated into three groups as follows; normal bone mass, osteopenia, and osteoporosis. All women underwent routine biochemical laboratory parameters, HCY, Vitamin B12, and CathK levels. Results: Among 93 postmenopausal women, 56% (52 had osteoporosis. Nineteen percent (18 had normal BMD (mean age, 53.22 ± 8.5 years and 23 (25% had osteopenia (mean age 52.86 ± 6.67 years. The mean age in the osteoporetic group was 56.2 ± 6.9 years. The median (interquartile range levels of HCY in the three groups were 14.5 μmol/L (12.2–24.7, 15.05 μmol/L (12.1–19.9 and 13.2 μmol/L (10.3–17.0, respectively. CathK levels were similar in three groups 7.6 ng/ml (7.0–80.5, 8.3 ng/ml (7.3–8.5, and 8.6 ng/ml (7.2–8.9. Both HCY and CathK were found positively associated with serum phosphorus (r = 0.584, P < 2.01 and r = 0.249, P < 0.05, respectively. Levels of HCY positively correlate with PTH (r = 0.303, P < 0.01 and inversely with Vitamin B12 (r = −0.248, P < 0.05. No significant association was seen between CathK level and 25(OH D, iPTH, serum calcium. Conclusion: Low bone mass by DXA is a significant problem in postmenopausal females. HCY and CathK do not reliably correlate with bone loss in

Women face societal and cultural barriers to breastfeeding. These challenges have been investigated in international studies and U.S. public opinion polls; however, mothers' experiences with breastfeeding in public in the United States remain unexplored. Research aim: The aim of this study was to describe the experiences of obese and normal-weight women with breastfeeding in public in central New York. Pregnant women ( N = 26) in central New York who intended to breastfeed and were either normal weight or obese were enrolled during their third trimester. A longitudinal, qualitative study was conducted to obtain information about women's experiences from birth through 3 to 6 months postpartum. Interviews were audio recorded, transcribed, and verified for accuracy. Transcripts were analyzed iteratively using conventional content analysis. The concept of "public" was situational rather than a set of physical places; women experienced challenges while breastfeeding around others in private locations that were indistinguishable from those they encountered in places typically considered public. Women experienced social and physical awkwardness including perceived lack of acceptability, fear of confrontation, exposure, and positioning difficulties. They used strategies to reduce awkwardness, for example, being "discreet" and minimizing breastfeeding around other people. Obese women experienced similar challenges but to a greater degree than normal-weight women. "Breastfeeding around others" described mother's experiences more accurately than "breastfeeding in public" and was experienced as awkward both socially and physically, particularly by obese women. Strategies are needed to normalize breastfeeding in the United States and to prepare mothers for the challenges of breastfeeding around others.

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

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

To investigate the effectiveness of calcitonin treatment of postmenopausal osteoporosis in relation to bone turnover, we examined 53 postmenopausal osteoporotic women before and after one year of therapy with salmon calcitonin (sCT), at the dose of 50 IU every other day. Baseline evaluation revealed that 17 (32%) patients had high turnover (HTOP), and 36 (68%) normal turnover osteoporosis (NTOP) as assessed by measurement of whole body retention (WBR) of 99mTc-methylene diphosphonate. The two groups did not differ in terms of bone mineral content (BMC) measured by dual photon absorptiometry at both lumbar spine and femoral diaphysis. However, HTOP patients had higher levels of serum osteocalcin (OC) and urinary hydroxyproline excretion (HOP/Cr). Multivariate regression analysis showed no correlation between parameters of bone turnover (WBR, OC, HOP/Cr) and both femoral and vertebral bone density; the latter being negatively correlated only with the years elapsed since menopause (R2 = 0.406). Treatment with sCT resulted in a significant increase of vertebral BMC in the 53 patients taken as a whole group (+/- 7%, P less than 0.001). When the results obtained in HTOP and NTOP were analyzed separately, only those with HTOP showed a marked increment of spinal BMC (+22%, P less than 0.001), NTOP subjects neither gained nor lost bone mineral during the study. Femoral BMC decreased in the whole group after sCT therapy (-3%, P less than 0.003). However, HTOP patients maintained initial BMC values, whereas those with NTOP lost a significant amount of bone during the study period (-5%, P less than 0.001). The increase of vertebral bone mass was associated with a marked depression of bone turnover detectable in both subsets of patients and in the whole group. (a) assessment of bone turnover cannot help predict the severity of bone loss in postmenopausal osteoporosis; (b) calcitonin therapy appears to be particularly indicated for patients with high-turnover osteoporosis

We sought to define 24-h glycemia in normal-weight and obese pregnant women using continuous glucose monitoring (CGM) while they consumed a habitual and controlled diet both early and late in pregnancy. Glycemia was prospectively measured in early (15.7 ± 2.0 weeks' gestation) and late (27.7 ± 1.7 weeks' gestation) pregnancy in normal-weight (n = 22) and obese (n = 16) pregnant women on an ad libitum and controlled diet. Fasting glucose, triglycerides (early pregnancy only), nonesterified fatty acids (FFAs), and insulin also were measured. The 24-h glucose area under the curve was higher in obese women than in normal-weight women both early and late in pregnancy despite controlled diets. Nearly all fasting and postprandial glycemic parameters were higher in the obese women later in pregnancy, as were fasting insulin, triglycerides, and FFAs. Infants born to obese mothers had greater adiposity. Maternal BMI (r = 0.54, P = 0.01), late average daytime glucose (r = 0.48, P fasting insulin (r = 0.49, P fasting triglycerides (r = 0.67, P fasting FFAs (r = 0.54, P obese women without diabetes have higher daytime and nocturnal glucose profiles than normal-weight women despite a controlled diet both early and late in gestation. Body fat in infants, not birth weight, was related to maternal BMI, glucose, insulin, and FFAs, but triglycerides were the strongest predictor. These metabolic findings may explain higher rates of infant macrosomia in obese women, which might be targeted in trials to prevent excess fetal growth.

2016-02-01

Full Text Available The article deals with the impact of diabetes mellitus (DM on the phosphorus and calcium metabolism in postmenopausal women, depending on the type and duration of the disease, duration of menopause, body mass and type of hypoglycemic therapy. The state of phosphorus and calcium metabolism in 86 women with type 1 DM (13 patients and type 2 DM (73 patients was studied. In all patients, the concentration of calcium and phosphorus in the blood was within normal limits. It was found that the concentration of ionized calcium, total calcium and inorganic phosphorus in the blood can not be the main criterion for the state of bone mineral density in postmenopausal women with DM. Sulfonylureas and insulin in combination with biguanides have no effect on the status of phosphorus and calcium metabolism in postmenopausal women with type 2 DM.

To quantify apparent diffusion coefficient (ADC) changes in fetuses with normal lungs and to determine whether ADC can be used in the assessment of fetal lung development. In 53 pregnancies (20-37th weeks of gestation), we measured ADC on diffusion-weighted imaging (DWI) in the apical, middle, and basal thirds of the right lung. ADCs were correlated with gestational age. Differences between the ADCs were assessed. Fetal lung volumes were measured on T2-weighted sequences and correlated with ADCs and with age. ADCs were 2.13 ± 0.44 μm 2 /ms (mean ± SD) in the apex, 1.99 ± 0.42 μm 2 /ms (mean ± SD) in the middle third, and 1.91 ± 0.41 μm 2 /ms (mean ± SD) in the lung base. Neither the individual ADC values nor average ADC values showed a significant correlation with gestational age or with lung volumes. Average ADCs decreased significantly from the lung apex toward the base. Individual ADCs showed little absolute change and heterogeneity. Lung volumes increased significantly during gestation. We have not been able to identify a pattern of changes in the ADC values that correlate with lung maturation. Furthermore, the individual, gravity-related ADC changes are subject to substantial variability and show nonuniform behavior. ADC can therefore not be used as an indicator of lung maturity. (orig.)

To quantify apparent diffusion coefficient (ADC) changes in fetuses with normal lungs and to determine whether ADC can be used in the assessment of fetal lung development. In 53 pregnancies (20-37th weeks of gestation), we measured ADC on diffusion-weighted imaging (DWI) in the apical, middle, and basal thirds of the right lung. ADCs were correlated with gestational age. Differences between the ADCs were assessed. Fetal lung volumes were measured on T2-weighted sequences and correlated with ADCs and with age. ADCs were 2.13 {+-} 0.44 {mu}m{sup 2}/ms (mean {+-} SD) in the apex, 1.99 {+-} 0.42 {mu}m{sup 2}/ms (mean {+-} SD) in the middle third, and 1.91 {+-} 0.41 {mu}m{sup 2}/ms (mean {+-} SD) in the lung base. Neither the individual ADC values nor average ADC values showed a significant correlation with gestational age or with lung volumes. Average ADCs decreased significantly from the lung apex toward the base. Individual ADCs showed little absolute change and heterogeneity. Lung volumes increased significantly during gestation. We have not been able to identify a pattern of changes in the ADC values that correlate with lung maturation. Furthermore, the individual, gravity-related ADC changes are subject to substantial variability and show nonuniform behavior. ADC can therefore not be used as an indicator of lung maturity. (orig.)

Polyunsaturated fatty acids are essential nutrients for the normal development of the brain. We investigated the associations between plasma polyunsaturated fatty acids and cognition in normal weight and overweight children. The study recruited 386 normal weight children and 58 overweight children aged six to eight years and blood samples were drawn after a 12-hour fast. We assessed plasma polyunsaturated fatty acids using gas chromatography, cognition using Raven's Coloured Progressive Matrices, and overweight and obesity using the age-specific and sex-specific cut-offs from the International Obesity Task Force. The data were analysed by linear regression analyses adjusted for age and sex. Higher proportions of eicosapentaenoic acid in plasma triacylglycerols (β = 0.311, p = 0.020, p = 0.029 for interaction) and docosahexaenoic acid in plasma triacylglycerols (β = 0.281, p = 0.038, p = 0.049 for interaction) were both associated with higher Raven's scores in overweight children but not in normal weight children. Higher eicosapentaenoic acid to arachidonic acid ratios in triacylglycerols (β = 0.317, p = 0.019) and phospholipids (β = 0.273, p = 0.046) were directly associated with the Raven's score in overweight children but not in normal weight children. These findings suggest that increasing the consumption of fish and other sources of eicosapentaenoic acid and docosahexaenoic acid may improve cognition among overweight children. ©2016 Foundation Acta Paediatrica.

Full Text Available Background: A woman is considered menopausal after 12 months of amenorrhea. The most feared symptom during menopause is postmenopausal bleeding which unless proved otherwise indicates genital malignancy. Objectives: To study Socio-demographic factors related to postmenopausal bleeding and to find time lapse between bleeding and reporting of these cases. Material and Methods: This cross sectional was done in the Department of Obstetrics & Gynecology, Pt. J. N. M. Medical College & DR. B. R. Ambedkar Memorial, Hospital, Raipur (C. G. The participants were 146 women who came with the complaint of postmenopausal bleeding. A detailed, preceded, pre-tested, structured, close ended questionnaire was used to collect the data. By interviewing these women, information was collected about different demographic factors like age, socio-economic status, parity etc. The collected data was put in the master chart and analyzed. Results: The proportion of postmenopausal bleeding cases was 3.5% .Maximum cases(50% with postmenopausal bleeding were found in the age group of 45-54yrs . 60 % of patients were from rural areas and 62% were illiterate. 65% of the patients were grand multipara (Parity4. Most of the patients belonged to lower socioeconomic strata. Almost half (48% of patients presented after, more than 6 months since the first episode of bleeding . Conclusions: The proportion of postmenopausal bleeding is high, requiring immediate investigation. Lack of awareness led to very late presentation of most of the patients, so education at community level is required to reduce this time lapse for earlier diagnosis and management

Studies of estrogen therapy in postmenopausal women provide evidence of an effect of sex hormones on cognitive function. Estrogen has demonstrated some utility in the prevention of normal, age-related decline in cognitive functions, especially in memory. The potential therapeutic utility of estrogens in schizophrenia is increasingly being recognized. Raloxifene, a selective estrogen receptor modulator (SERM), appears to act similarly to conjugated estrogens on dopamine and serotonin brain systems, and may be a better option since it lacks the possible negative effects of estrogen on breast and uterine tissue. We assessed the utility of raloxifene as an adjuvant treatment for cognitive symptoms in postmenopausal women with schizophrenia in a 12-week, double-blind, randomized, placebo-controlled study. Patients were recruited from both the inpatient and outpatient departments. Thirty-three postmenopausal women with schizophrenia (DSM-IV) were randomized to receive either adjuvant raloxifene (16 women) or adjuvant placebo (17 women) for three months. The main outcome measures were: Memory, attention and executive functions. Assessment was conducted at baseline and week 12. The total sample is homogenous with respect to: age, years of schooling, illness duration, baseline symptomatology and pharmacological treatment. The addition of raloxifene (60 mg) to regular antipsychotic treatment showed: we found significant differences in some aspects of memory and executive function in patients treated with raloxifene. This improvement does not correlate with clinical improvement. The use of raloxifene as an adjuvant treatment in postmenopausal women with schizophrenia seems to be useful in improving cognitive symptoms. © 2013 Published by Elsevier B.V. and ECNP.

There is sufficient evidence supporting a relationship between increased body mass index (BMI) and an increased risk for breast cancer among postmenopausal women. However, most studies have found a decreased risk for premenopausal breast cancer. This study was conducted to find out the different effects of BMI on the risk of breast cancer among premenopausal and postmenopausal women, and explore the potential factors that influence the associations. A dose-response meta-analysis with 3,318,796 participants from 31 articles was conducted. Cohort studies that included BMI and corresponding breast cancer risk were selected through various databases including PubMed, Medline, Web of Science, the China National Knowledge Infrastructure (CNKI) and Chinese Scientific Journals (VIP). Random effects models were used for analyzing the data. The summary relative risks (RRs) were 1.33 (95%CI: 1.20-1.48) and 0.94(95%CI: 0.80-1.11) among postmenopausal and premenopausal women, respectively. The dose-response meta-analysis indicated a positive non-linear association between BMI and breast cancer risk among postmenopausal women, and compared to the mean level of the normal BMI category (21.5 kg/m 2 ) the RR in total postmenopausal women were1.03 (95% CI: 1.02-1.05) per 1 kg/m 2 increment. However, no statistically significant association among total premenopausal women was detected. In subgroup analysis among European premenopausal women, the summary RR was 0.79(95%CI: 0.70-0.88). The non-linear relationship showed a negative non-linear association between BMI and breast cancer risk among European premenopausal women. When compared to the mean level of the normal BMI category, the RRs were 0.98 (95%CI: 0.96-1.00) per 1 kg/m 2 increment, respectively. In line with previous studies BMI had different effects on pre-menopausal and postmenopausal breast cancer risk. However, contrary to previous studies, a high BMI was not associated with decreased risk in total pre-menopausal women

This study investigated the effect of a low-fat, plant-based diet on body weight, metabolism, and insulin sensitivity, while controlling for exercise in free-living individuals. In an outpatient setting, 64 overweight, postmenopausal women were randomly assigned to a low-fat, vegan diet or a control diet based on National Cholesterol Education Program guidelines, without energy intake limits, and were asked to maintain exercise unchanged. Dietary intake, body weight and composition, resting metabolic rate, thermic effect of food, and insulin sensitivity were measured at baseline and 14 weeks. Mean +/- standard deviation intervention-group body weight decreased 5.8 +/- 3.2 kg, compared with 3.8 +/- 2.8 kg in the control group (P = .012). In a regression model of predictors of weight change, including diet group and changes in energy intake, thermic effect of food, resting metabolic rate, and reported energy expenditure, significant effects were found for diet group (P effect of food (P vegan diet was associated with significant weight loss in overweight postmenopausal women, despite the absence of prescribed limits on portion size or energy intake.

Objective: To explore the characteristics and the clinical application of MR perfusion weighted imaging (PWI) in the normal kidneys and the renal diseases. Methods: Thirty-one subjects including 9 cases without urinary diseases, 14 cases with renal carcinoma, 6 cases with renal cyst and 2 cases with renal tuberculosis who had been examined with T 1 WI, T 2 WI and PWI were analyzed retrospectively. All the data were processed by a workstation to obtain time-signal intensity curves, color perfusion maps and relative perfusion value. The relative renal blood volume (RBV), relative renal blood flow (RBF), mean transition time (MTY) and the time to peak (TTP) in the normal renal cortex and medulla and the renal lesions were calculated. Comparisons between the right and the left normal kidneys, and between the cortex and the medulla of the normal kidneys were performed using t test, and comparisons between the normal and the abnormal kidneys were performed using q test. Results: Relative RBV and relative RBF of the cortex were 1.33±0.08 and 1.44±0.09 respectively, and for medulla were 0.58± 0.05 and 0.78±0.13 respectively (t=9.2241 and 5.0336, P 0.05). The values of relative RBF of the renal carcinoma (1.35±0.34) were significantly higher than that of the normal tissues (1.02±0.06) (q=3.0882, P< 0.01). Conclusion: PWI is able to demonstrate the hemodynamic change of the normal renal tissues and the renal lesions, and it maybe an ideal method for showing the functional changes of the kidney and for differentiating the renal diseases.

Increased exposure to estrogen is a risk factor for postmenopausal breast cancer, and dietary factors can influence estrogen metabolism. However, studies of diet and breast cancer have been inconclusive. We developed a dietary pattern associated with levels of unconjugated estradiol and the ratio of 2- and 16-hydroxylated estrogen metabolites in a subsample of Prostate, Lung, Colorectal and Ovarian Screening Trial (PLCO) participants (n = 653) using reduced rank regression, and examined its association with postmenopausal breast cancer prospectively in the larger PLCO cohort (n = 27,488). The estrogen-related dietary pattern (ERDP) was comprised of foods with positively-weighted intakes (non-whole/refined grains, tomatoes, cruciferous vegetables, cheese, fish/shellfish high in ω-3 fatty acids, franks/luncheon meats) and negatively-weighted intakes (nuts/seeds, other vegetables, fish/shellfish low in ω-3 fatty acids, yogurt, coffee). A 1-unit increase in the ERDP score was associated with an increase in total (HR: 1.09, 95% CI: 1.01-1.18), invasive (HR: 1.13; 95% CI: 1.04-1.24) and estrogen receptor (ER)-positive (HR: 1.13, 95% CI: 1.02-1.24) breast cancer risk after adjustment for confounders. Associations were observed for the fourth quartile of ERDP compared with the first quartile for overall breast cancer (HR: 1.14; 95% CI: 0.98-1.32), invasive cases (HR: 1.20, 95% CI: 1.02-1.42) and ER-positive cases (HR: 1.19; 95% CI: 0.99-1.41). The increased risk associated with increasing ERDP score was more apparent in strata of some effect modifiers (postmenopausal hormone therapy non-users and non-obese participants) where the relative estrogen exposure due to that factor was lowest, although the p values for interaction were not statistically significant. Results suggest a dietary pattern based on estrogen metabolism is positively associated with postmenopausal breast cancer risk, possibly through an estrogenic influence. © 2018 UICC.

In healthy normal-weight adults, cinnamon reduces blood glucose concentration and enhances insulin sensitivity. Insulin resistance, resulting in increased fasting and postprandial blood glucose and insulin levels, is commonly observed in obese individuals. The objective of the study was to compare declines in postprandial glycemic response in normal-weight and obese subjects with ingestion of 6 g ground cinnamon. In a crossover study, subjects consumed 50 g available carbohydrate in instant farina cereal, served plain or with 6 g ground cinnamon. Blood glucose concentration, the main outcome measure, was assessed at minutes 0, 15, 30, 45, 60, 90, and 120. Repeated-measures analysis of variance evaluated the effects of body mass index (BMI) group, dietary condition, and time on blood glucose. Paired t-test assessed blood glucose at individual time points and glucose area under the curve (AUC) between dietary conditions. Thirty subjects between the ages of 18 and 30 years, 15 with BMIs between 18.5 and 24.9 and 15 with BMIs of 30.0 or more, completed the study. There was no significant difference in blood glucose between the two BMI groups at any time point. However, in a combined analysis of all subjects, the addition of cinnamon to the cereal significantly reduced 120-minute glucose AUC (P=0.008) and blood glucose at 15 (P=0.001), 30 (Pblood glucose was significantly higher with cinnamon consumption (Pglucose response in normal weight and obese adults.

The aim of the present study was to assess the effect of dietary macronutrients on postprandial incretin responses and satiety and hunger sensation in obese and normal-weight women. A total of eleven obese and nine normal-weight women were recruited for the assessment of plasma concentrations of glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP) and insulin and the sensation of satiety and hunger using a visual analogue scale before and during a 6 h period after administration of three different macronutrient test meals. The AUCtotal GLP-1 and AUCtotal GIP values were decreased in obese women after the consumption of a fatty meal and all the test meals, respectively. However, the AUCtotal insulin value after a carbohydrate meal was greater in the obese group. The AUCtotal satiety value was decreased only after the intake of the protein meal in obese women when compared with normal-weight women. After the consumption of the fatty meal, a significant positive correlation between maximum satiety sensation and the AUCtotal GLP-1 value in the obese group and that between minimum hunger sensation and the AUCtotal GLP-1 value in the normal-weight group were observed. In conclusion, the findings of the present study suggest that: (1) satiety sensation after consumption of carbohydrate and protein meals in the obese group is related to the postprandial insulin response, while after consumption of a fatty meal, it is related to the postprandial GLP-1 release; (2) the postprandial GIP response does not influence the sensation of satiety and hunger; (3) the reduced GLP-1 release after the intake of a fatty meal in obese individuals may explain impaired satiety sensation; (4) the impaired postprandial GIP response is not related to the consumption of macronutrients and may be the early indicator of incretin axis dysfunction in obese women.

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

This study aimed to investigate the relationship between serum vitamin D level and carotid intima-media thickness (C-IMT) in Chinese postmenopausal women. Nine hundred and twenty six Chinese postmenopausal women without carotid artery plaque or history of cardiovascular disease were selected for analysis. Measurements of serum 25 hydroxyvitamin D3 (25(OH)D3) concentration and C-IMT were made by electrochemiluminescence immunoassay and B-mode ultrasound, respectively. Trend analysis was conducted according to tertiles of C-IMT. The median serum 25(OH)D3 level was 11.03 ng/mL, with an interquartile range of 8.22-14.70. A decreasing trend of serum 25(OH)D3 level was accompanied by increased C-IMT tertiles (P for trend = 0.001). Correlation analysis found an inverse relationship between serum 25(OH)D3 level and C-IMT (r = -0.113, P = 0.001). After adjustment for confounding factors, multiple regression analysis showed that serum 25(OH)D3 level independently and negatively associated with C-IMT (Standard β = -0.112, P women with normal glucose tolerance, blood pressure and body mass index, and without undergoing lipid-lowering therapy (standard β = -0.140, P = 0.018). Serum 25(OH)D3 level was inversely correlated with C-IMT in Chinese postmenopausal women.

Twenty-four-hour plasma tryptophan concentrations and ratios are below normal in obese subjects and are not normalized by substantial weight reduction

Breum, Leif; Rasmussen, Michael H; Hilsted, Jannik

2003-01-01

BACKGROUND: Plasma tryptophan concentrations and the ratio of tryptophan to other large neutral amino acids (plasma tryptophan ratio) are reportedly low in obese subjects. The plasma tryptophan ratio predicts brain tryptophan uptake and serotonin production. If this ratio is low in obese subjects......, serotonin function may also be low. Plasma tryptophan concentrations and ratios have been measured only at single time points in obese subjects; it is not known whether low values for these 2 variables persist throughout a 24-h period. OBJECTIVE: Our objective was to determine whether plasma tryptophan...... concentrations and ratios in obese subjects are lower than those in normal-weight subjects throughout a 24-h period and whether they increase when body weight is reduced. DESIGN: Plasma tryptophan concentrations and ratios were examined in obese subjects before and after weight loss and in nonobese control...

Materials and Methods: Hundred thirty-seven postmenopausal women with osteoporosis admitted to our outpatient clinic were included in the study. A questionnaire that was including patients’age, marital status, education level, occupation, height, weight was completed. Risk factors of osteoporosis were recorded. major and minor risk factors were determined according to Canadian diagnosis and treatment guideline. DXA was used to determine bone mineral density of the lumbar spine and femoral neck. Thoracal and lumbar compression fractures were evaulated with thoracal and lumbar radiography. The diagnosis of fibromyalgia was according to the 1990 American College of Rheumatology (ACR criteria. Results: Twenty-six (19% of 137 postmenopausal women with osteoporosis had fibromyalgia. Ninety-four (68.6% of all patients were married and 43 (31.4% of all patients were not married, 63 (46% of all patients were literate, 74 (54% of all patients were illiterate. The average age of patients was 73.56±6.17. According to the results of logistic regression analysis, advanced age, to be married, the number of major risk factors and the decrease of lomber and femur bone mineral density were found to be risk factors for fibromyalgia. Educational level, BMI and the number of minor risk factors were not found to be a risk factors for fibromyalgia. Conclusion: It is importatnt to be careful for fibromyalgia not only in premenopousal women but also in postmenopausal osteoporotic women. (Turkish Journal of Osteoporosis 2014;20: 1-5

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

In response to food cues, obese vs normal-weight individuals show greater activation in brain regions involved in the regulation of food intake under both fasted and sated conditions. Putative effects of obesity on task-independent low-frequency blood-oxygenation-level-dependent signals-that is, resting-state brain activity-in the context of food intake are, however, less well studied. To compare eyes closed, whole-brain low-frequency BOLD signals between severely obese and normal-weight females, as assessed by functional magnetic resonance imaging (fMRI). Fractional amplitude of low-frequency fluctuations were measured in the morning following an overnight fast in 17 obese (age: 39±11 years, body mass index (BMI): 42.3±4.8 kg m - 2 ) and 12 normal-weight females (age: 36±12 years, BMI: 22.7±1.8 kg m - 2 ), both before and 30 min after consumption of a standardized meal (~260 kcal). Compared with normal-weight controls, obese females had increased low-frequency activity in clusters located in the putamen, claustrum and insula (Pfood intake. Self-reported hunger dropped and plasma glucose concentrations increased after food intake (Pfood intake under the experimental settings applied in the current study. Future studies involving males and females, as well as utilizing repeated post-prandial resting-state fMRI scans and various types of meals are needed to further investigate how food intake alters resting-state brain activity in obese humans.

Full Text Available The purpose of this study was to examine changes in aerobic fitness, muscular strength, bone mineral density (BMD and body composition during inpatient treatment of underweight and normal weight patients with longstanding eating disorders (ED. Twenty-nine underweight (BMI < 18.5, n = 7 and normal weight (BMI ≥ 18.5, n = 22 inpatients (mean (SD age: 31.0 (9.0 years, ED duration: 14.9 (8.8 years, duration of treatment: 16.6 (5.5 weeks completed this prospective naturalistic study. The treatment consisted of nutritional counseling, and 2 × 60 min weekly moderate intensive physical activity in addition to psychotherapy and milieu therapy. Underweight patients aimed to increase body weight with 0.5 kg/week until the weight gain goal was reached. Aerobic fitness, muscular strength, BMD and body composition were measured at admission and discharge. Results showed an increase in mean muscular strength, total body mass, fat mass, and body fat percentage, but not aerobic capacity, among both underweight and normal weight patients. Lumbar spine BMD increased among the underweight patients, no changes were observed in BMD among the normal weight patients. Three out of seven underweight patients were still underweight at discharge, and only three out of nine patients with excessive body fat (i.e., >33% managed to reduce body fat to normal values during treatment. These results calls for a more individualized treatment approach to achieve a more optimal body composition among both underweight and normal to overweight patients with longstanding ED.

Do overweight women with polycystic ovary syndrome (PCOS) have a higher risk of perinatal complications than normal weight women with PCOS? Overweight women with PCOS with an ongoing singleton pregnancy have an increased risk of preterm birth as well as an increased risk of giving birth to a baby with a higher birthweight than normal weight women with PCOS. There is evidence that overweight (BMI > 25 kg/m²) has a negative influence on the prevalence of gestational diabetes mellitus and fetal macrosomia in women with PCOS. We set up a retrospective comparative cohort study of 93 overweight (BMI ≥ 25 kg/m²) and 107 normal weight (BMI weight women was, respectively, 30.8 kg/m² [interquartile quartile range (IQR) 5.8] and 20.9 kg/m² (IQR 2.3) (P weight women (all P weight (2/71) women [adjusted odds ratio 0.1, 95% confidence interval (CI) 0-0.6, P = 0.01]. The mean birthweight of newborns was significantly higher in overweight (3386 ± 663 g) than in normal weight (3251 ± 528 g) women (adjusted mean difference 259.4, 95% CI 83.4-435.4, P = 0.004). Our results only represent the pregnancy, delivery and neonatal outcome of ongoing singleton pregnancies. The rather small sample size and observational nature of the study are further limitations. Our results suggest the importance of pre-pregnancy weight loss in overweight women with PCOS in order to reduce the risk of adverse perinatal outcomes.

In postmenopausal women, the presence of risk factors for coronary artery disease (CAD) increases. However, the difference in prevalence of ischemia between pre- and postmenopausal women with multiple risk factors for CAD has not been well established. To compare the prevalence of ischemia on Tc{sup 99m}-sestamibi myocardial perfusion scintigraphy (MPS) in pre-and postmenopausal women, and to evaluate whether menopause can be considered an independent risk predictor of ischemia in women with multiple risk factors for CAD. This study retrospectively assessed 500 MPS of pre- and postmenopausal women with multiple risk factors for CAD. Statistical analysis was performed by using Fisher exact test and univariate and multivariate analysis, a p value ≤ 0.05 being considered significant. Postmenopausal women represented 55.9% of the sample; 83.3% were hypertensive; 28.9%, diabetic; 32.1%, smokers; 25%, obese; 61.2% had high cholesterol levels; and 34.3% had known CAD. Postmenopausal women were more often hypertensive, diabetic and dyslipidemic, and had lower functional capacity on exercise testing (p = < 0.005). The presence of ischemia on MPS did not significantly differ between the pre- and postmenopausal groups (p = 0.395). The only variable associated with ischemia on MPS was known CAD (p = 0.004). The results suggest that, in women with multiple risk factors for CAD, menopause was not an independent predictor of ischemia on MPS. Those data support the idea that the investigation of ischemia via MPS in women with multiple risk factors for CAD should begin prior to menopause.

Body image concerns in binge eating disorder (BED) have been examined almost exclusively in overweight individuals with BED. The current study extends past research by including overweight and normal weight BED and non-BED groups to assess the multifactorial construct of body image using subscales of the Eating Disorder Examination 16.0 (EDE-16.0) and a Body Comparison Task. Independent of weight status and when controlling for age and race, women with BED are distinguished from those without BED by significantly greater overvaluation of shape and weight on the EDE-16.0 and significantly reduced weight satisfaction after a Body Comparison Task. Both BED diagnosis and weight status were independently associated with Weight Concern and Shape Concern subscales on the EDE-16.0. Taken together, these data provide further support for the consideration of body image concerns in the diagnostic criteria for BED. Copyright © 2017 Elsevier Ltd. All rights reserved.

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.

The aim of this study was to examine the relationships among physical self-perception, body image and motor performance in Italian middle school students. Two hundred and sixty children were categorized into normal-weight (n=103), overweight (n=86) or obese (n=71) groups. Perceived coordination, body fat and sports competence were assessed using the Physical Self-Description Questionnaire, while body image was measured using Collins' Child Figure Drawings. Individuals' perceptions of strength, speed and agility were assessed using the Perceived Physical Ability Scale. Tests involving the standing long jump, 2 kg medicine-ball throw, 10 × 5 m shuttle-run and 20 and 30 m sprints were also administered. Girls, when compared with boys, and overweight and obese participants, when compared with normal-weight peers, reported lower perceived and actual physical competence, higher perceived body fat and greater body dissatisfaction. Body dissatisfaction mediated all the associations between body mass index (BMI) and the different aspects of physical self-perception in boys, but not in girls. The same pattern of results was found for physical self-perception as a mediator of the relationship between BMI and body dissatisfaction. In conclusion, obesity proved to have adverse effects on both motor performance and physical self-perception. © 2010 John Wiley & Sons A/S.

The goal of this study was to estimate life expectancy (LE) and LE with disability (LwD) among normal weight, overweight, and obese smokers and nonsmokers in Western Europe. Data from four waves (1998-2001) of the European Community Household Panel (ECHP) were used; a standardized multipurpose annual longitudinal survey. Self-reported health and socioeconomic information was collected repeatedly using uniform questionnaires for 66,331 individuals in nine countries. Health status was measured in terms of disability in daily activities. Multistate Markov (MSM) models were applied to obtain hazard ratios (HRs) and age-specific transition rates according to BMI and smoking status. Multistate life tables were computed using the predicted transition probabilities to estimate LE and LwD. Significant associations were observed between disability incidence and BMI (HR = 1.15 for overweight, HR = 1.64 for obese, compared to normal weight). The risk of mortality was negatively associated with overweight status among disabled (HR = 0.77). Overweight people had higher LE than people with normal-weight and obesity. Among women, overweight and obese nonsmokers expect 3.6 and 6.1 more years of LwD than normal weight persons, respectively. In contrast, daily smokers expect lower LE but a similar LwD. The same patterns were observed among people with high education and those with low education. To conclude, daily smoking is associated with mortality more than with disability, whereas obesity is associated with disability more than with mortality. The findings suggest that further tobacco control would contribute to increasing LE, while tackling the obesity epidemic is necessary to prevent an expansion of disability.

To determine the independent and commingling effect of android and gynoid percent fat (measured using Dual Energy X-Ray Absorptiometry) on cardiometabolic dysregulation in normal weight American adults. The 2005-2006 data (n=1802) from the United States National Health and Nutritional Examination Surveys (NHANES) were used in this study. Associations of android percent fat, gynoid percent fat and their joint occurrence with risks of cardiometabolic risk factors were estimated using prevalence odds ratios from logistic regression analyses. Android-gynoid percent fat ratio was more highly correlated with cardiometabolic dysregulation than android percent fat, gynoid percent fat or body mass index. Commingling of android and gynoid adiposities was associated with much greater odds of cardiometabolic risk factors than either android or gynoid adiposities. Commingling of android and gynoid adiposities was associated with 1.75 (95% confidence interval (CI)=1.42-2.93), 1.48 (95% CI=1.32-1.91), 1.61 (95% CI=1.50-1.89), 3.56 (95% CI=2.91-4.11) and 1.86 (95% CI=1.49-1.96) increased odds of elevated glucose, elevated blood pressure, elevated low-density lipoprotein-cholesterol, elevated triglyceride and low high-density lipoprotein-cholesterol, respectively. Normal weight subjects who present with both android and gynoid adiposities should be advised of the associated health risks. Both android and gynoid fat accumulations should be considered in developing public health strategies for reducing cardiometabolic disease risk in normal weight subjects.

Abstract The primary aim of this study was to evaluate metabolically healthy status (MHS) among participants in obesity, overweight, and normal weight groups and characteristics associated with this phenotype using baseline data of Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The secondary aim was to investigate agreement among 4 different MHS criteria. This cross-sectional study included 14,545 participants aged 35 to 74 years with a small majority (54.1%) being women. Of all participants, 22.7% (n = 3298) were obese, 40.8% (n = 5934) were overweight, and 37.5% (n = 5313) were of normal weight. Socio-demographic, behavioral, and anthropometric factors related to MHS were ascertained. Logistic regression models estimated the odds of associations. We used 4 different criteria separately and in combination to define MHS: the National Health and Nutrition Examination Survey (NHANES), the National Cholesterol Education Program (NCEP-ATPIII), the International Diabetes Federation (IDF) and comorbidities, and the agreement between them were evaluated by Cohen-kappa coefficient. MHS was present among 12.0% (n = 396) of obese, 25.5% (n = 1514) of overweight, and 48.6% (n = 2582) of normal weight participants according to the combination of the 4 criteria. The agreement between all the 4 MHS criteria was strong (kappa 0.73 P < 0.001). In final logistic models, MHS was associated with lower age, female sex, lower body mass index (BMI), and weight change from age 20 within all BMI categories. This study showed that, despite differences in prevalence among the 4 criteria, MHS was associated with common characteristics at every BMI category. PMID:27399079

To evaluate the metabolic changes in urinary steroids in pre- and post-menopausal women and men with papillary thyroid carcinoma (PTC). Quantitative steroid profiling combined with gas chromatography-mass spectrometry was used to measure the urinary concentrations of 84 steroids in both pre- (n = 21, age: 36.95 ± 7.19 yr) and post-menopausal female (n = 19, age: 52.79 ± 7.66 yr), and male (n = 16, age: 41.88 ± 8.48 yr) patients with PTC. After comparing the quantitative data of the patients with their corresponding controls (pre-menopause women: n = 24, age: 33.21 ± 10.48 yr, post-menopause women: n = 16, age: 49.67 ± 8.94 yr, male: n = 20, age: 42.75 ± 4.22 yr), the levels of steroids in the patients were normalized to the mean concentration of the controls to exclude gender and menopausal variations. Many urinary steroids were up-regulated in all PTC patients compared to the controls. Among them, the levels of three active androgens, androstenedione, androstenediol and 16α-hydroxy DHEA, were significantly higher in the pre-menopausal women and men with PTC. The corticoid levels were increased slightly in the PTC men, while progestins were not altered in the post-menopausal PTC women. Estrogens were up-regulated in all PTC patients but 2-hydroxyestrone and 2-hydroxy-17β-estradiol were remarkably changed in both pre-menopausal women and men with PTC. For both menopausal and gender differences, the 2-hydroxylation, 4-hydroxylation, 2-methoxylation, and 4-methoxylation of estrogens and 16α-hydroxylation of DHEA were differentiated between pre- and post-menopausal PTC women (P < 0.001). In particular, the metabolic ratio of 2-hydroxyestrone to 2-hydroxy-17β-estradiol, which could reveal the enzyme activity of 17β-hydroxysteroid dehydrogenase, showed gender differences in PTC patients (P < 1 × 10 -7 ). These results are expected be helpful for better understanding the pathogenic differences in PTC according to gender and menopausal conditions

Obesity is associated with risks for mother and infant, and the mothers' dietary habits influence breast milk composition. Polyamines are secreted in breast milk and are essential for the regulation of intestinal and immune function in newborns and infants. The present study aimed to investigate the level of polyamines in human milk obtained from obese and normal weight mothers at different times of lactation. Breast milk from 50 mothers was obtained at day 3, and at 1 and 2 months after delivery. The mothers had normal body weight [body mass index (BMI) obese (BMI > 30 kg/m(2) ). A subgroup of obese mothers participated in a weight reduction programme during pregnancy. Polyamines were analysed using high-performance liquid chromatography. The total polyamine content was significantly lower at all times in breast milk from obese mothers compared to milk from controls. Spermine levels did not differ between groups at any time in contrast to the levels of putrescine and spermidine. Putrescine concentrations were highest on day 3 and spermidine and spermine were highest at 1 month of lactation. The obese mothers, who received dietary advice during pregnancy based on the Nordic Nutrition Recommendations, had higher concentrations of putrescine and spermidine in their milk than the obese mothers without any intervention. Polyamine concentrations were lower in breast milk from obese mothers compared to mothers with a normal weight. General dietary intervention in obese mothers increased the polyamine levels, suggesting that the low levels in obesity were at least partly associated with food habits. However, the consistency of spermine suggests a special metabolic function of this polyamine. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Only a few studies have been published on the postprandial effects of different fatty acids in obese subjects. Therefore, the present study investigated the effects of three test meals containing palm oil (PO), lard (LD), or puff-pastry margarine (PPM), all normal dietary ingredients, on postprandial lipid and hormone responses in normal-weight and obese young women. The study was performed as a randomized, crossover design. The fats differed in the content of palmitic acid, stearic acid, and trans monounsaturated fatty acids allowing a dietary comparison of different 'solid' fatty acids. The obese women had significantly higher fasting concentrations and postprandial responses of plasma total triacylglycerol (TAG), chylomicron-TAG, and insulin compared with the normal-weight women but there was no significant difference in the postprandial responses between the three test meals. The obese women had fasting concentrations of leptin four times greater than the normal-weight women. There were no postprandial changes in the concentrations of leptin. The fasting concentrations of HDL-cholesterol were significantly lower in the obese women than in the normal-weight women, whereas there was no significant difference between the two groups in the concentrations of total cholesterol or LDL-cholesterol. These results provide evidence that obese women have exaggerated lipid and hormone responses compared with normal-weight women but the different contents of saturated and trans monounsaturated fatty acids provided by PO, LD, and PPM have no effect in either group.

Unusual cause of acute abdominal pain in a postmenopausal woman: adnexal torsion

Full Text Available Adnexal torsion is an infrequent but significant cause of acute lower abdominal pain in women. While adnexal torsion is generally considered in premenopausal women presenting with acute abdominal pain and a pelvic mass, it is a rare cause of acute abdominal pain during postmenopausal period. The diagnosis of adnexal torsion is often challenging due to nonspesific clinical, laboratory and physical examination findings. Causes of adnexal torsion is also different in premenopausal and postmenopausal women. While a simple functional cyst is often the cause of torsion in premenopausal women, it is more rarely the cause in postmenopausal women. Adnexal torsion is a surgical emergency. The surgery of adnexal torsion is performed either via conventional exploratory laparotomy or laparoscopic surgery. Adnexal torsion in postmenopausal women should be considered not only in the setting of sudden onset pain, but also in long-term abdominal discomfort. In this article, we presented a case with adnexal torsion that rarely cause acute abdominal pain in postmenopausal women. [Cukurova Med J 2016; 41(1.000: 167-170

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

Aside from the health consequences, observational studies indicate that being overweight may also negatively affect cognitive function. However, existing evidence has to a large extent not controlled for the possible confounding effect of having different lifestyles. Therefore, the objective was to examine the independent associations between weight status and lifestyle indicators with cognitive performance in 8-11year old Danish children. The analyses included 828 children (measured in 2011-2012) each having one to three measurement occasions separated by approximately 100days. Dietary intake, physical activity, sedentary time, and sleep duration were measured using dietary records and accelerometers. The Children's Sleep Habits Questionnaire was used to access sleep problems and the Andersen test was carried out to estimate cardio-respiratory fitness (CRF). Weight status (underweight, normal weight, and overweight/obese) was defined according to body mass index and cognitive performance was assessed using the d2-test of attention, a reading test, and a math test. A linear mixed model including a number of fixed and random effects was used to test associations between lifestyle indicators as well as BMI category and cognitive performance. After adjustment for demographics, socioeconomics, and multiple lifestyle indicators, normal weight children had higher cognitive test scores than overweight/obese and underweight children of up to 89% and 48% of expected learning within one school year (Pbreakfast consumption, fewer sleep problems, higher CRF, less total physical activity, more sedentary time, and less light physical activity were associated with higher cognitive performance independently of each other in at least one of the three cognitive tests (Pperformance compared to overweight/obese as well as underweight children, independent of multiple lifestyle indicators.

Introduction To determine the prevalence of sexual dysfunction in pre and postmenopausal women. Material and methods A cross-sectional, descriptive, comparative study was done in climacteric women from 40 to 59 years of age. Female sexual function was evaluated with the female sexual function index (FSFI) on the day of consultation. The comparison between pre and postmenopausal women and between those with or without sexual dysfunction was done with Mann Whitney U test, χ2, and Spearman’s correlation analysis was done. Results One hundred and ten women were studied, 55 were premenopausal (group 1) and 55 postmenopausal (group 2). The median of age in group 1 was 46 (40-58) years and in group 2 it was 53 (45-60) years. Premenopausal women had higher education level than postmenopausal women (p < 0.023). From those sexually active, 62.1% had sexual dysfunction. No statistically significant difference was found in education level, religion and marital status between women with or without sexual dysfunction. No difference in sexual dysfunction was found between premenopausal (62.1%) and postmenopausal (62.5%) women, but greater sexual dysfunction was found starting from 50 years age. Age negatively correlated with FSFI score (ρ = –0.324, p < 0.001). Conclusion In postmenopausal women, those older had a greater impairment in sexual function.

Full Text Available Introduction and Objectives: Microvascular angina is common in postmenopausal women. Myocardial ischemia was induced by stress testing, and reports have been published about the relationship between endothelial dysfunction and myocardial perfusion. The objective of this research was to determine whether myocardial ischemia can be evidenced by abnormalities in perfusion and function, as detected by myocardial scintigraphy in women with typical angina, normal coronary angiography and endothelial dysfunction. Methods: 59 women underwent lipid and endothelial function measurements by brachial artery ultrasound, in addition, a 24-hour ECG study (Holter. During the scintigraphy a stress-rest protocol was applied. Patients were divided into two groups according to presence (group I or absence (group II of myocardial perfusion defects. Results: 21 patients showed perfusion defects. 57 % of group I exhibited greater endothelial dysfunction. Only twelve patients showed reversible perfusion defects, and 75 % of the cases was associated with a reduction of post-stress left ventricular ejection fraction, greater than 5 %, and regional abnormalities of wall motion. Three patients in group I showed evidence of ischemia compared with four in Group II. Conclusions: The stress-induced ischemia was associated with a reduced post-stress ejection fraction and endothelial dysfunction in the studied women, and no ischemic changes in the Holter were found.

BackgroundGiven the usefulness of the product of triglycerides and glucose (TyG) to recognize individuals at high risk for developing cardiovascular events, the aim of this study was to determine whether the TyG index is associated with the presence of cardiovascular risk factors in apparently healthy normal-weight children and adolescents.MethodsApparently healthy children and adolescents with normal weight, aged 6-15 years, were enrolled in a population-based cross-sectional study. The children were allocated into groups with and without cardiovascular risk factors. Cardiovascular risk factors were considered as the occurrence of at least one of the following: elevated blood pressure, hypertriglyceridemia, low high-density lipoprotein cholesterol (HDL-C), or hyperglycemia.ResultsA total of 2,117 children and adolescents were enrolled in the study; of them, 1,078 (50.9%) participants exhibited cardiovascular risk. The adjusted logistic regression analysis showed that elevated TyG index was significantly associated with hypertriglyceridemia (odds ratio (OR)=96.45, 95% confidence interval (CI): 48.44-192.04), low HDL-C (OR=2.07, 95% CI: 1.46-2.92), and hyperglycemia (OR=3.11, 95% CI: 2.05-4.72), but not with elevated blood pressure (OR=1.39, 95% CI: 0.89-2.16).ConclusionThe elevated TyG index is associated with the presence of cardiovascular risk factors in healthy normal-weight children and adolescents.

Primary hyperparathyroidism (PHPT) is a common endocrinopathy, frequently caused by a parathyroid adenoma, rarely by a parathyroid carcinoma that lacks effective oncological treatment. As the majority of cases are present in postmenopausal women, oestrogen signalling has been implicated in the tumourigenesis. Oestrogen receptor beta 1 (ERB1) and ERB2 have been recently identified in parathyroid adenomas, the former inducing genes coupled to tumour apoptosis. We applied immunohistochemistry and slide digitalisation to quantify nuclear ERB1 and ERB2 in 172 parathyroid adenomas, atypical adenomas and carcinomas, and ten normal parathyroid glands. All the normal parathyroid glands expressed ERB1 and ERB2. The majority of tumours expressed ERB1 (70.6%) at varying intensities, and ERB2 (96.5%) at strong intensities. Parathyroid carcinomas expressed ERB1 in three out of six cases and ERB2 in five out of six cases. The intensity of tumour nuclear ERB1 staining significantly correlated inversely with tumour weight (P=0.011), and patients whose tumours were classified as ERB1-negative had significantly greater tumour weight as well as higher serum calcium (P=0.002) and parathyroid hormone levels (P=0.003). Additionally, tumour nuclear ERB1 was not expressed differentially with respect to sex or age of the patient. Levels of tumour nuclear ERB2 did not correlate with clinical characteristics. In conclusion, decreased ERB1 immunoreactivity is associated with increased tumour weight in parathyroid adenomas. Given the previously reported correlation with tumour-suppressive signalling, selective oestrogen receptor modulation (SERMs) may play a role in the treatment of parathyroid carcinomas. Future studies of SERMs and oestrogen treatment in PHPT should consider tumour weight as a potential factor in pharmacological responsiveness. © 2015 The authors.

Immediate effects of low-, medium-, and high-energy foods on the emotional state of normal-weight and overweight women were studied experimentally. Nineteen normal-weight (body mass index [BMI]: 19-25 kg/m2) and 19 overweight women (BMI: 26-40 kg/m2) aged 18-40 years received samples of food that differed in energy content (low vs. medium vs. high energy) and rated their emotional state immediately after eating. Perceived characteristics of the foods and associations elicited by the foods were also obtained. Negative emotions (anger, fear, shame, and sadness) and sleepiness increased, while happiness decreased with energy of foods. Emotionally negative associations were more frequent, while positive emotions were less frequent the higher the energy content of the foods. Sadness, shame, fear, and sleepiness after eating high-energy food tended to be more intense in overweight women. Additional analyses demonstrated influences of eating habits, e.g., disinhibition. The higher the energy content of a food stimulus, the more it was viewed as "unhealthy" and "dangerous." It is suggested that immediate food-induced changes of emotions can be explained by activation of associative emotion networks.

The focus of several studies in recent years has been the association between increased plasma concentrations of homocysteine (Hcy), reduced bone mineral density and increased risk of bone fractures. Nevertheless, inconsistencies persist in the literature. Thus, the objective of this study was to investigate the possible relationship between serum Hcy and vitamin B12 status, and bone mineral density, on a group of post-menopausal women. One hundred thirty-nine postmenopausal women were recruited to enter this cross-sectional study. Bone mineral density (BMD) of total hip, femoral neck and lumbar spine was measured by dual-energy X-ray absorptiometry (DXA) and serum Hcy, vitamin B12, parathyroid hormone (PTH), total calcium and magnesium levels were determined. In addition, we investigated the relationship of Hcy and vitamin B12 and BMD using a meta-analysis approach. Serum Hcy levels were significantly higher in osteoporotic women when compared to other BMD groups, and were inversely related to lumbar spine BMD and femur neck BMD. Body mass index and serum Hcy levels were shown to be significant predictors of BMD at lumbar spine, femur neck and total hip. The performed meta-analysis showed that serum Hcy levels were significantly higher in osteoporotic subjects compared to normal BMD subjects. This study shows that Hcy status, but not vitamin B12 status, is associated with BMD in this cohort of postmenopausal women. We therefore confirm that high Hcy levels are an independent risk factor for osteoporosis. BMD evaluation in women at post menopause with high Hcy levels may be helpful in advising precautionary measures.

Bone mass loss associated with pregnancy and lactation is usually regained in the postpartum period. However, it is not known whether the bone loss is completely recovered in women with a shortened interpregnancy interval (IPI). The aim of this study was to analyze the effect of IPI and gynecological history on postmenopausal osteoporosis. The study was conducted among 537 postmenopausal women who were divided into two groups in accordance with the osteoporosis status. Prior to bone densitometry, the patients were questioned about reproductive history. Dual-energy X-ray absorptiometry was used to measure lumbar spinal, femur neck and total femoral bone mineral density. Association between IPI and postmenopausal osteoporosis was analyzed. The comparison of both groups according to the total duration of breastfeeding did not reveal a considerable variation (p=0.288). In the osteoporosis group the age and duration of menopause were found to be significantly higher (ppregnancy and IPI were notably lower in comparison to the controls group (posteoporosis (OR: 4.306; 95% CI, 1.684-11.01). This analysis confirmed that the occurrence of first pregnancy under 27 years of age conveyed a higher risk for osteoporosis, as well. Shortened IPI may have a detrimental effect on bone mineral density in postmenopausal age. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

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

Full Text Available Menopause is a natural event to be experienced by every woman and appears to be associated with increased risk for developing type 2 diabetes mellitus. It has been postulated that a diet high in legumes may be beneficial for the prevention of glycosuria. These unique components of soy have been shown to have beneficial effects on glucose and insulin homeostasis. The objective of the present study was to examine the possibility of an association between soy food consumption and risk of glycosuria in postmenopausal women. A cross-sectional study was conducted among 94 postmenopausal women attending Mampang Prapatan Health Center, Mampang Prapatan subdistrict, South Jakarta. Anthropometric measurements were taken using standard instruments and dietary intake was assessed with a validated food-frequency questionnaire. A dipstick semiquantitative assay for urinary glucose was used to define glycosuria (positive. The results showed that 12.8% of postmenopausal women had glycosuria and mean isoflavone intake was 69.5 ± 61.4 g/d. Intake of isoflavone was inversely associated with risk of glycosuria. Compared to women in the lowest quintile of isoflavone intake (Q1, postmenopausal women in the highest quintile (Q5 had a lower risk for glycosuria of 0.30 times that of Q1, which risk was however statistically not significant (OR = 0.30; 95% CI = 0.02 – 3.14. In conclusion, isoflavone may play a role in the prevention of glycosuria (an important indicator of diabetes among postmenopausal women.

Strontium ranelate is a new treatment for osteoporosis therefore, its benefits and harms need to be known. To determine the efficacy and safety of strontium ranelate for the treatment and prevention of postmenopausal osteoporosis. We searched MEDLINE (1996 to March 2005), EMBASE (1996 to week 9 2005), the Cochrane Library (1996 to Issue 1 2005), reference lists of relevant articles and conference proceedings from the last two years. Additional data was sought from authors. We included randomized controlled trials (RCTs) of at least one year duration comparing strontium ranelate versus placebo reporting fracture incidence, bone mineral density (BMD), health related quality of life or safety in postmenopausal women. Treatment (versus prevention) population was defined as women with prevalent vertebral fractures and/or lumbar spine BMD T score gastritis or death. Additional data suggests that the risk of vascular and nervous system side-effects is slightly increased with taking 2 g of strontium ranelate daily over three to four years. There is silver level evidence (www.cochranemsk.org) to support the efficacy of strontium ranelate for the reduction of fractures (vertebral and to a lesser extent non-vertebral) in postmenopausal osteoporotic women and an increase in BMD in postmenopausal women with/without osteoporosis. Diarrhea may occur however, adverse events leading to study withdrawal were not significantly increased with taking 2 g of strontium ranelate daily. Potential vascular and neurological side-effects need to be further explored.

There is increasing evidence suggesting that adiponectin plays a role in the regulation of bone metabolism. This was a cross-sectional study of 34 post-menopausal women with and 37 without osteoporosis. All subjects had body mass index (BMI), bone mineral density (BMD), total-, high molecular weight (HMW)-adiponectin and their ratio, osteoprotegerin (OPG), a marker of bone resorption (betaCTX) and formation (P1NP) measured. We observed a positive correlation between BMI and BMD (r=0.44, plean subjects but there was no difference between those with or without osteoporosis. There were significant negative correlations between HMW/total-adiponectin ratio and BMI (r=-0.27, p=0.030) and with OPG (r=-0.44, pproduction of OPG thereby affecting osteoclasts mediated bone resorption.

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

We aimed to compare expression levels of antiapoptotic and proapoptotic genes in parametrial and vaginal tissues from postmenopausal women with and without pelvic organ prolapse (POP). We hypothesized that the expression of genes that induce apoptosis may be altered in vaginal and parametrial tissues in postmenopausal women with POP. Samples of vaginal and parametrial tissues were obtained from postmenopausal women with (n = 10) and without (n = 10) POP who underwent vaginal or abdominal hysterectomy. Expression levels of antiapoptotic (BCL-2, BCL-XL) and proapoptotic (BAX, BAD) genes were studied by real-time reverse-transcription polymerase chain reaction (RT-PCR). Gene expression levels of BCL-2 (P gene expression levels of BCL-2 (p gene expression levels differed significantly between postmenopausal women with and without POP. Bcl-2 family genes were overexpressed in the parametrium of patients with POP compared with vaginal tissue, suggesting that the processes responsible for POP have a greater effect on parametrial tissue than vaginal tissue during the development of POP.

2002-06-01

This study investigated the presence of the False Consensus Effect (FCE) with body and shape-related attitudes in 30 normal weight women who scored high or low on a measure of concern with body shape. The participants were asked to rate depressive, positive, neutral, and body shape self-statements for relevance to self and to others. They also estimated the percentage of individuals that would agree with each attitudinal statement. Women with high body shape concerns rated themselves and others as significantly more likely to agree with the statements expressing such concerns than those with low concerns. They also believed that a significantly higher percentage of others would favor those attitudes. This pattern of findings is supportive of the presence of a FCE in normal weight women preoccupied with body shape and size.

Update on raloxifene: role in reducing the risk of invasive breast cancer in postmenopausal women

Full Text Available Victor G Vogel Cancer Institute, Geisinger Health System, Danville, PA, USA Abstract: Risk factors allow us to define women who are at increased lifetime risk for breast cancer, and the most important factor is age. Benign breast disease increases risk, and the most important histologies are atypical lobular or ductal hyperplasia and lobular carcinoma in situ. Family history of breast cancer among first-degree relatives (mother, sisters, daughters also increases risk. Quantitative measures of risk give accurate predictions of breast cancer incidence for groups of women but not for individual subjects. Multiple published, randomized controlled trials, which employed selective estrogen receptor (ER modulators (SERMs, have demonstrated consistent reductions of 35% or greater in the risk of ER-positive invasive and noninvasive breast cancer in postmenopausal women. Professional organizations in the US now recommend the use of SERMs to reduce the risk of breast cancer in high-risk, postmenopausal women. Raloxifene and tamoxifen reduce the risk of ER-positive invasive breast cancer with equal efficacy, but raloxifene is associated with a lower risk of thromboembolic disease, benign uterine conditions, and cataracts than tamoxifen in postmenopausal women. No evidence exists establishing whether a reduction in breast cancer risk from either agent translates into reduced breast cancer mortality. Overall quality of life is similar with raloxifene or tamoxifen, but the incidence of dyspareunia, weight gain, and musculoskeletal complaints is higher with raloxifene use, whereas vasomotor symptoms, bladder incontinence, gynecologic symptoms, and leg cramps were higher with tamoxifen use.

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

Full Text Available The main of this study was to examine the relationship between plasma homocysteine (Hcy, asymptomatic osteoporotic vertebral fractures (VFs using vertebral fracture assessment (VFA and prevalent abdominal aortic calcification (AAC in Moroccan postmenopausal women. The study cohort consisted of 188 consecutive postmenopausal women with no prior known diagnosis of osteoporosis or taking medication interfering with bone metabolism. Mean age, weight, height, body mass index and plasma homocysteine were determined. Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a Lunar Prodigy Vision densitometer (GE Healthcare Inc., Waukesha, WI. VFs were defined using a combination of Genant’s semiquantitative approach and morphometry. VFA images were also scored for prevalent AAC using a validated 24 point scale. Fifty-eight (30.9% patients had densitometric osteoporosis. VFs were identified using VFA in 76 (40.4% patients: 61 women had grade 1 VFs and 15 had grade 2 or 3 VFs. One hundred twenty nine women (68.6% did not have any detectable AAC, whereas the prevalence of significant atherosclerotic burden defined as AAC score of 5 or higher, was 13.8%. A significant positive correlation between AAC score and homocysteine was observed. Women with extended AAC, were older, had a lower weight, BMI and BMD, higher homocysteine levels and more prevalent VFs than women without extended AAC. Multiple regression analysis showed that the presence of extended AAC was significantly associated with Age and grade 2/3 VFs and not independently associated with homocysteine levels.This study did not confirm that homocysteine is important determinant of extended AAC in postmenopausal women. However, this significant atherosclerotic marker is independently associated with VFs regardless of age.

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

We showed that obese insulin resistant postmenopausal women are characterized by higher lean body mass and elevated C-reactive protein. Although counterintuitive, we hypothesized that losses in muscle mass following caloric restriction and increase in muscle quality will be associated with improvements in glucose homeostasis through decreases in C-reactive protein. To determine 1) if improvements in C-reactive protein concentrations occurs through losses in lean body mass; and 2) if decreases in C-reactive protein levels contribute to improvements in insulin sensitivity. 50 postmenopausal women (body mass index>26 kg/m(²)) with impaired glucose disposal (program. Outcome measures were: Glucose disposal rate: M value (by hyperinsulinemic-euglycemic clamp), body composition (total, trunk, and appendicluar). LBM and FM by DXA), LBM index (LBM (kg)/height (m(2)), body fat distribution (VAT and SAT by CT scan) and plasma high-sensitive C-reactive protein (hsCRP) and interleukin-6 (Il-6). Significant correlations were observed between Δ hsCRP levels with Δ Il-6 (r=0.33, p≤0.05), Δ total LBM index (r=0.44, p≤0.01), Δ trunk LBM (r=0.38, p≤0.01) Δ SAT (r=0.35, p≤0.05) and ∆ glucose disposal rate (r=- 0.44, p≤0.01). After including all the correlated variables in Stepwise linear regression model, Δ LBM index was the only independent predictor of the reduction in hsCRP levels (R(2)=0.20, p≤0.01). Losses in total lean body mass are independently associated with improvements in inflammatory state (CRP levels) in obese postmenopausal women with impaired glucose disposal. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Introduction: Osteoporosis is a disease characterized by bone strength disorder and weakness of the entire skeleton causing the predisposition to fractures to grow. Identification of factors which may influence pathological fractures in postmenopausal women and determining which of the identified factors have the largest influence on the development of osteoporotic fractures. A retrospective study has included 400 postmenopausal women with newly diagnosed osteoporosis examined at the Institute of Rheumatology in Belgrade. We have examined demographic data and the following fracture risk factors: physical activity, menarche, menopause, fractures after the age of forty, osteoporotic fractures in the family, comorbidity: inflammatory rheumatic diseases, intestine diseases, chronic kidney insufficiency and endocrinopathy (hyperthyroidism and diabetes and taking glucocorticoid therapy. The value of bone density has been measured using DXA method in the spine and hip, and the body mass index has been calculated based on the body height and weight. Logistic regression has been used as the method for analyzing the relation between binary results and potential predictors. Statistical hypotheses have been tested at the statistical significance level of 0.05. In the model of multivariate logistic regression, the significant predictors of osteoporotic fractures are as follows: older age (B = 0.13; p = 0.001, higher BMI values (B = 0.094; p = 0.022 and lower BMD values (hip (B = -3.060; p = 0.023. Elderly overweight women with lower BMD values in the hip are more susceptible to fractures due to osteoporosis; therefore this subgroup of postmenopausal women is important for the application of the measures of primary and secondary prevention of osteoporotic fractures.

Risk assessment of future breast cancer risk through exposure to sex steroids currently relies on clinical scorings such as mammographic density. Knowledge about the gene expression patterns in existing breast cancer tumors may be used to identify risk factors in the breast tissue of women still free of cancer. The differential effects of estradiol, estradiol together with gestagens, or tibolone on breast cancer-related gene expression in normal breast tissue samples taken from postmenopausal women may be used to identify gene expression profiles associated with a higher breast cancer risk. Breast tissue samples were taken from 33 healthy postmenopausal women both before and after a six month treatment with either 2mg micronized estradiol [E2], 2mg micronized estradiol and 1mg norethisterone acetate [E2+NETA], 2.5mg tibolone [T] or [no HRT]. Except for [E2], which was only given to women after hysterectomy, the allocation to each of the three groups was randomized. The expression of 102 mRNAs and 46 microRNAs putatively involved in breast cancer was prospectively determined in the biopsies of 6 women receiving [no HRT], 5 women receiving [E2], 5 women receiving [E2+NETA], and 6 receiving [T]. Using epithelial and endothelial markers genes, non-representative biopsies from 11 women were eliminated. Treatment of postmenopausal women with [E2+NETA] resulted in the highest number of differentially (pbreast tissue with a change in the expression of genes putatively involved in breast cancer. Our data suggest that normal mammary cells triggered by [E2+NETA] adjust for steroidogenic up-regulation through down-regulation of the estrogen-receptor pathway. This feasibility study provides the basis for whole genome analyses to identify novel markers involved in increased breast cancer risk. Copyright © 2011 Federation of European Biochemical Societies.

Introduction: Postmenopausal bleeding (PMB) is defined as bleeding that occurs after 1 year of amenorrhea in a woman who is not receiving hormone replacement therapy (HRT). About 10% of women with postmenopausal bleeding have a primary or secondary malignancy. Common malignancies among them are endometrial cancer (80%), cervical cancer or an ovarian tumour. Endometrial cancer is the second most common cancer associated with hereditary non-polyposis colorectal cancer. Ninety percent of patients have benign causes. Objective: The objective of this study was to determine the frequency of endometrial carcinoma in patients with post-menopausal bleeding. Study Design: Descriptive case series study. Setting: Department of obstetrics and gynaecology, Lady Willingdon, Lahore. Duration of Study: This study was conducted over a period of six months from January, 1 2009 to June 30, 2009. Subjects and Methods: 50 cases with postmenopausal bleeding. Results: During the period of this study a total number of 50 consecutive patients who met inclusion criteria were enrolled in the study. Ages of the patients who presented with PMB ranged between 48 years and 80 years with a mean age of 59 years. Malignancy was found in 18 out of 50 cases (36%).Cases with endometrial CA were 14 out of 50 cases (28%) and CA cervix constituted 4 out of 50 cases (8%). Benign pathology was more frequent (64%). 13 of 50 cases (26%) had hyperplasia out of which 1 case (2%) was of atypical hyperplasia. Endometrial polyp was found in 4 of 50 cases (8%). 3 of 50 cases (6%) had chronic endometritis. 5 of 50 cases (10%) had chronic cervicitis. While 7 cases (14%) had postmenopausal bleeding due to decubitus ulcer of uterovaginal prolapse. Among malignancies (36%), endometrial cancer is the most frequent malignancy in women with postmenopausal bleeding with mean age of 65 years. Conclusion: In this study it was concluded that the majority of cases of PMB would be expected to be suffering from benign problems

Oligomenorrhea in active adolescent females of normal weight is presumed to be related to hypoestrogenism secondary to physical activity and decreased fat mass. We hypothesized that active adolescents with oligomenorrhea would have lower estrogen levels than normal controls with similar levels of cardiovascular fitness. Twenty healthy participants between the ages of 16 and 20 years were recruited at least 2 years postmenarche. Adolescents reporting fewer than 9 cycles a year (n = 6) were compared to 14 controls with monthly menstrual cycles. Histories of eating disorder, hirsutism, severe acne, depression, or amenorrhea were cause for exclusion. Body composition and bone density were measured by total body dual x-ray absorpitometry. Cardiovascular fitness was evaluated by measuring oxygen consumption during exercise. Control subjects were matched by age, body mass index (BMI), and fitness level. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, progesterone, and estradiol were obtained. Statistical analysis was performed using SAS 9.1. Cardiovascular fitness in both groups was within normal limits for age. No significant differences in BMI, estradiol concentrations, or bone density were found, but trunk fat mass was lower in adolescents with oligomenorrhea who also reported more frequent exercise. Testosterone concentrations and LH/FSH ratios were significantly higher in participants with irregular menstrual cycles (P = 0.0018 and exercise-induced oligomenorrhea.

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

Full Text Available In this study 29 normal (mean age: 65.6 ± 5.1 years and 33 osteopenic (mean age: 67.6 ± 4.9 years postmenopausal women according to total bone mineral density (BMD of the hip were evaluated for BMD values of subregions of proximal femur. The percentages for osteoporosis and osteopenia with respect to subregions were 13.8% and 58.6% for femoral neck and 20.7% and 41.4% for Ward’s triangle in normal group. In trochanteric and intertrochanteric measurements there were no T scores below –2.5 but 17.2% of the subjects were osteopenic with regard to trochanteric and 6.9% were osteopenic due to intertrochanteric BMD values. The percentages for osteoporosis and osteopenia with respect to subregion measurements were 57.6% and 42.4% for femoral neck, 60.6% and 36.4% for Ward’s triangle, 3% and 78.8% for trochanteric, 9.1% and 87.9% for intertrochanteric regions in osteopenic group according to total hip values. Knowing that hip fracture risk is increasing 2-3 fold for 1 standart deviation decrease from the young adult mean value for all subregions and knowing the relation between cervical hip fractures and BMD values of Ward’s triangle and femoral neck and the relation between intertrochanteric fractures and trochanteric BMD values, it is recommended to evaluate the BMD values of subregions of the hip besides the total hip values in daily practice.

Full Text Available Abstract Introduction: The key to successful treatment of OSAS is to individually tailor such treatment. Thus, it is very important to determine the severity of OSAS, its pattern, and the extent of collapse, by gender, age, and BMI. Objective: The objective of the study was to understand the characteristics of obstructive sleep apnea in postmenopausal women by comparing postmenopausal and premenopausal subjects, and men, using DISE. We hope that our work will help the medical community to consult on, diagnose, and treat OSAS more effectively. Methods: A total of 273 patients (195 males and 78 females diagnosed with OSAS were enrolled. Female patients were divided into pre-menopausal (n = 41 and post-menopausal patients (n = 37. The group of post-menopausal female patients was matched with a group of male patients with similar age and body mass index (BMI. DISE findings were compared between pre-menopausal female patients and post-menopausal female patients, and also between post-menopausal female patients and male patients matched for age and BMI. Results: Upon PSG examination, post-menopausal patients (who had a significantly higher BMI than did pre-menopausal patients; 25.6 kg/m2 vs. 23.5 kg/m2; p = 0.019 tended to have a higher AHI and a lower lowest SaO2, but the differences did not attain statistical significance.

Cucker-Smale model with normalized communication weights and time delay

KAUST Repository

Choi, Young-Pil

2017-03-06

We study a Cucker-Smale-type system with time delay in which agents interact with each other through normalized communication weights. We construct a Lyapunov functional for the system and provide sufficient conditions for asymptotic flocking, i.e., convergence to a common velocity vector. We also carry out a rigorous limit passage to the mean-field limit of the particle system as the number of particles tends to infinity. For the resulting Vlasov-type equation we prove the existence, stability and large-time behavior of measure-valued solutions. This is, to our best knowledge, the first such result for a Vlasov-type equation with time delay. We also present numerical simulations of the discrete system with few particles that provide further insights into the flocking and oscillatory behaviors of the particle velocities depending on the size of the time delay.

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

To investigate if TVT-Abbrevo has similar outcomes in normal weight and overweight patients. Retrospective evaluation of 205 (105 normal weight women and 100 overweight women with BMI ≥ 25 kg/m(2)) undergone TVT-Abbrevo positioning with 12 month follow-up. Primary outcomes were objective cure rate (defined as no leakage during CST) and subjective cure rate ("very much improved"/"much improved" at PGI-I), secondary outcomes were intra-operative and post-operative complications. Objective cure rates in the normal and overweight groups were 96.2% and 94%, respectively (p=.47). Subjective cure rates in the normal and overweight groups were 90.5% and 88%, respectively (p=.57). ICIQ-SF, I-QoL and PGI-S scores significantly improved in both groups with no differences between the two groups. No serious intra- or post-operative complications were observed. No differences were observed in pain VAS scores and number of analgesic vials administered. TVT-Abbrevo seems to have similar efficacy and safety in normal weight and overweight women. More studies are needed to assess the efficacy of this device in frankly obese women and long-term outcomes. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Normal weight ( n  = 40, body mass index Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann-Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. The average age of the total cohort was 15.9 ± 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean ± standard deviation 28.3 ± 9.3 vs 18.1 ± 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0-26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet. These differences persisted after adjustment for age, sex, paternal education, and family income. Overweight/obese adolescents did not lack autonomous motivation but demonstrated higher controlled motivation and perceived competence for healthy eating in comparison to normal weight adolescents, independent of socioeconomic factors. In the clinical practice of weight management, providers should carefully assess adolescents for type of

Full Text Available ObjectiveEstradiol (E2 regulates adipose tissue resulting in increased fat mass (FM with declining E2. However, increased visceral fat and hyperestrogenemia are features of obese individuals. It is possible that adipocytes in obese individuals are less sensitive to E2 resulting in higher FM. Our objective is to identify the range of serum E2 for which postmenopausal women have the lowest FM and best body composition.MethodsCross-sectional data from 252 community-dwelling postmenopausal women, 42–90 years old. Subjects were stratified into categories of E2 (pg/ml: (1 ≤10.5; (2 10.6–13.9; (3 14.0–17.4; and (4 ≥17.5. Body composition by dual-energy X-ray absorptiometry. Serum E2 by radioimmunoassay.

While fat-free mass (FFM, kg increased with increasing E2 (p < 0.001, % FFM was highest in group 3.ConclusionIn our population of postmenopausal women, FM followed a U-shaped distribution according to E2 levels. E2 between 14.0 and 17.4 pg/ml is associated with the best body composition, i.e., lowest total and % FM and highest % FFM. Given the role of E2 in regulating body fat, high FM at the high end of the E2 spectrum may suggest reduced E2 sensitivity in adipocytes among obese postmenopausal women.Clinical TrialsClinicalTrials.gov identifier: NCT00146107.

Full Text Available Objective: The focus of several studies in recent years has been the association between increased plasma concentrations of homocysteine (Hcy, reduced bone mineral density and increased risk of bone fractures. Nevertheless, inconsistencies persist in the literature. Thus, the objective of this study was to investigate the possible relationship between serum Hcy and vitamin B12 status, and bone mineral density, on a group of post-menopausal women. Materials and methods: One hundred thirty-nine postmenopausal women were recruited to enter this cross-sectional study. Bone mineral density (BMD of total hip, femoral neck and lumbar spine was measured by dual-energy X-ray absorptiometry (DXA and serum Hcy, vitamin B12, parathyroid hormone (PTH, total calcium and magnesium levels were determined. In addition, we investigated the relationship of Hcy and vitamin B12 and BMD using a meta-analysis approach. Results: Serum Hcy levels were significantly higher in osteoporotic women when compared to other BMD groups, and were inversely related to lumbar spine BMD and femur neck BMD. Body mass index and serum Hcy levels were shown to be significant predictors of BMD at lumbar spine, femur neck and total hip. The performed meta-analysis showed that serum Hcy levels were significantly higher in osteoporotic subjects compared to normal BMD subjects. Conclusion: This study shows that Hcy status, but not vitamin B12 status, is associated with BMD in this cohort of postmenopausal women. We therefore confirm that high Hcy levels are an independent risk factor for osteoporosis. BMD evaluation in women at post menopause with high Hcy levels may be helpful in advising precautionary measures.

Obesity and osteoporosis are chronic disorders with increasing prevalence worldwide. The aim of this study was to investigate the association between obesity and fracture in postmenopausal women from Santa Maria, Brazil. A cross-sectional study was carried out at Santa Maria (parallel 29° south), Brazil. Postmenopausal women aged ≥55 yr who had at least 1 appointment at the primary care in the 2 years before the study were recruited from March 1, 2013 to August 31, 2013. The Global Longitudinal Study of Osteoporosis in Women study questionnaire was applied with permission of The Center for Outcomes Research, University of Massachusetts Medical School. Height and weight were measured according to the World Health Organization protocol. Bone fractures (excluding hand, feet, and head) that occurred after the age of 45 yr were considered as the outcome. Overall, 1057 women completed the study, of whom 984 had body mass index measured. The mean (standard deviation) age and body mass index of the women included in the study were 67.1 (7.6) yr and 29.2 (5.5) kg/m(2), respectively. The prevalence of fractures in obese and nonobese women was similar (17.3% vs 16.0%); 41.4% of all fractures occurred in obese women. Obese postmenopausal women make a substantial contribution to the overall burden of prevalent fractures in this population. Our results provide further evidence in support of the concept that obesity is not protective against fracture. Copyright © 2015 The International Society for Clinical Densitometry.

We investigated whether there were gender differences in the effect of obesity on bone mineral density (BMD) based on menopausal status. 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. 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.

Neural correlates to food-related behavior in normal-weight and overweight/obese participants.

Directory of Open Access Journals (Sweden)

Alan Ho

Full Text Available Two thirds of US adults are either obese or overweight and this rate is rising. Although the etiology of obesity is not yet fully understood, neuroimaging studies have demonstrated that the central nervous system has a principal role in regulating eating behavior. In this study, functional magnetic resonance imaging and survey data were evaluated for correlations between food-related problem behaviors and the neural regions underlying responses to visual food cues before and after eating in normal-weight individuals and overweight/obese individuals. In normal-weight individuals, activity in the left amygdala in response to high-calorie food vs. nonfood object cues was positively correlated with impaired satiety scores during fasting, suggesting that those with impaired satiety scores may have an abnormal anticipatory reward response. In overweight/obese individuals, activity in the dorsolateral prefrontal cortex (DLPFC in response to low-calorie food cues was negatively correlated with impaired satiety during fasting, suggesting that individuals scoring lower in satiety impairment were more likely to activate the DLPFC inhibitory system. After eating, activity in both the putamen and the amygdala was positively correlated with impaired satiety scores among obese/overweight participants. While these individuals may volitionally suggest they are full, their functional response to food cues suggests food continues to be salient. These findings suggest brain regions involved in the evaluation of visual food cues may be mediated by satiety-related problems, dependent on calorie content, state of satiation, and body mass index.

Full Text Available Introduction: Bisphenol A and several of the most commonly used phthalates have been associated with adverse metabolic health effects such as obesity and diabetes. Therefore, we analyzed these man-made chemicals in first morning urine samples from 107 healthy normal-weight Danish children and adolescents. Method: This was a cross-sectional study. Participants were recruited as part of the Copenhagen Puberty Study. The subjects were evaluated by an oral glucose tolerance test (OGTT, a dual-energy X-ray absorptiometry (DXA scan, direct oxygen uptake measurement during cycle ergometry and fasting blood samples. First morning urine was collected and phthalate metabolites and BPA were measured by liquid chromatography-tandem mass spectrometry (LC–MS/MS with prior enzymatic deconjugation. Individual chemical concentrations were divided into tertiles and analyzed in relation to biological outcome. Results: Children in the lowest tertile of urinary BPA had significantly higher peak insulin levels during OGTT (P = 0.01, lower insulin sensitivity index (P < 0.01, higher leptin (P = 0.03, triglyceride (P < 0.01 and total cholesterol levels (P = 0.04, lower aerobic fitness (P = 0.02 and a tendency toward higher fat mass index (P = 0.1 compared with children in the highest tertile for uBPA. No significant differences in anthropometrics, body composition or glucose metabolism were associated with any of the phthalate metabolites measured. Conclusion: This pilot study on healthy normal-weight children suggests an inverse association between BPA and insulin resistance. Our findings contrast other cross-sectional studies showing a positive association for BPA, which may be due to confounding or reverse causation because diet is an important source of both BPA exposure and obesity.

The effect of hormone replacement therapy (HRT) on body weight in postmenopausal women is controversial, with studies reporting an increase, a decrease, and no change in body weight. To examine estrogen receptor actions on body weight, we investigated the effects of treatment with a selective estrogen receptor modulator (SERM) on body weight, food intake, and activity and metabolic rate in a nonhuman primate model. Eighteen ovariectomized female rhesus monkeys were treated with a nonsteroidal SERM (GSK232802A, 5 mg/kg po) for 3 mo. GSK232802A decreased lutenizing hormone (P Physical activity increased during the 3rd mo of treatment (P = 0.04). Baseline activity level and the change in activity due to treatment were correlated, with the most sedentary individuals exhibiting increased physical activity during the 1st mo of treatment (P = 0.02). Metabolic rate did not change (P = 0.58). These results indicate that GSK232802A treatment reduces body weight and adiposity in ovariectomized nonhuman primates by suppressing food intake and increasing activity, particularly in the most sedentary individuals. These findings suggest that SERM treatment may counteract weight gain in postmenopausal women.

We determined the prevalence of osteosarcopenic obesity (loss of bone and muscle coexistent with increased adiposity) in overweight/obese postmenopausal women and compared their functionality to obese-only women. Results showed that osteosarcopenic obese women were outperformed by obese-only women in handgrip strength and walking/balance abilities indicating their higher risk for mobility impairments. Osteosarcopenic obesity (OSO) is a recently defined triad of osteopenia/osteoporosis, sarcopenia, and adiposity. We identified women with OSO in overweight/obese postmenopausal women and evaluated their functionality comparing them with obese-only (OB) women. Additionally, women with osteopenic/osteoporotic obesity (OO), but no sarcopenia, and those with sarcopenic obesity (SO), but no osteopenia/osteoporosis, were identified and compared. We hypothesized that OSO women will have the lowest scores for each of the functionality measures. Participants (n = 258; % body fat ≥35) were assessed using a Lunar iDXA instrument for bone and body composition. Sarcopenia was determined from negative residuals of linear regression modeled on appendicular lean mass, height, and body fat, using 20th percentile as a cutoff. Participants with T-scores of L1-L4 vertebrae and/or total femur OSO (n = 32) included women with both osteopenia/osteoporosis and sarcopenia, while those with normal bone and no sarcopenia were classified as OB (n = 99). Functionality measures such as handgrip strength, normal/brisk walking speed, and right/left leg stance were evaluated and compared among groups. Women with OSO presented with the lowest handgrip scores, slowest normal and brisk walking speed, and shortest time for each leg stance, but these results were statistically significantly different only from the OB group. These findings indicate a poorer functionality in women presenting with OSO, particularly compared to OB women, increasing the risk for bone fractures and immobility from

2017-01-01

Full Text Available Intermittent energy restriction (IER has become popular as a means of weight control amongst people who are overweight and obese, and is also undertaken by normal weight people hoping spells of marked energy restriction will optimise their health. This review summarises randomised comparisons of intermittent and isoenergetic continuous energy restriction for weight loss to manage overweight and obesity. It also summarises the potential beneficial or adverse effects of IER on body composition, adipose stores and metabolic effects from human studies, including studies amongst normal weight subjects and relevant animal experimentation. Six small short term (<6 month studies amongst overweight or obese individuals indicate that intermittent energy restriction is equal to continuous restriction for weight loss, with one study reporting greater reductions in body fat, and two studies reporting greater reductions in HOMA insulin resistance in response to IER, with no obvious evidence of harm. Studies amongst normal weight subjects and different animal models highlight the potential beneficial and adverse effects of intermittent compared to continuous energy restriction on ectopic and visceral fat stores, adipocyte size, insulin resistance, and metabolic flexibility. The longer term benefits or harms of IER amongst people who are overweight or obese, and particularly amongst normal weight subjects, is not known and is a priority for further investigation.

Using Image Gradients to Improve Robustness of Digital Image Correlation to Non-uniform Illumination: Effects of Weighting and Normalization Choices

KAUST Repository

Xu, Jiangping

2015-03-05

Changes in the light condition affect the solution of intensity-based digital image correlation algorithms. One natural way to decrease the influence of illumination is to consider the gradients of the image rather than the image itself when building the objective function. In this work, a weighted normalized gradient-based algorithm, is proposed. This algorithm optimizes the sum-of-squared difference between the weighted normalized gradients of the reference and deformed images. Due to the lower sensitivity of the gradient to the illumination variation, this algorithm is more robust and accurate than the intensity-based algorithm in case of illumination variations. Yet, it comes with a higher sensitivity to noise that can be mitigated by designing the relevant weighting and normalization of the image gradient. Numerical results demonstrate that the proposed algorithm gives better results in case of linear/non-linear space-based and non-linear gray value-based illumination variation. The proposed algorithm still performs better than the intensity-based algorithm in case of illumination variations and noisy data provided the images are pre-smoothed with a Gaussian low-pass filter in numerical and experimental examples.

Normal Weight but Low Muscle Mass and Abdominally Obese: Implications for the Cardiometabolic Risk Profile in Chronic Obstructive Pulmonary Disease.

It is well established that low muscle mass affects physical performance in chronic obstructive pulmonary disease (COPD). We hypothesize that combined low muscle mass and abdominal obesity may also adversely influence the cardiometabolic risk profile in COPD, even in those with normal weight. The cardiometabolic risk profile and the responsiveness to 4 months high-intensity exercise training was assessed in normal-weight patients with COPD with low muscle mass stratified by abdominal obesity. This is a cross-sectional study including 81 clinically stable patients with COPD (age 62.5 ± 8.2 years; 50.6% males; forced expiratory volume in 1 second 55.1 ± 19.5 percentage predicted) with fat-free mass index risk profile. Triglycerides showed a significant decrease, while the HOMA-IR increased. Abdominal obesity is highly prevalent in normal-weight patients with COPD with low muscle mass who showed an increased cardiometabolic risk compared with patients without abdominal obesity. This cardiometabolic risk profile was not altered after 4 months of exercise training. Copyright © 2017 AMDA – The Society for Post-Acute and Long-Term Care Medicine. Published by Elsevier Inc.

After a single cholecalciferol load, peak serum 25-hydroxycholecalciferol (25OHD) is lower in individuals with a higher body mass index (BMI), probably due to it being distributed in a greater volume. Its subsequent disappearance from the serum is slower the higher the individual's BMI, probably due to the combination of a larger body volume and a slower release into the circulation of vitamin D stored in adipose tissue. The aim of the study is to examine 25-hydroxycholecalciferol (25OHD) response to a single oral load of cholecalciferol in the normal weight, overweight, and obese. We considered 55 healthy women aged from 25 to 67 years (mean ± SD, 50.8 ± 9.5) with a BMI ranging from 18.7 to 42 kg/m(2) (mean ± SD, 27.1 ± 6.0). The sample was divided into three groups by BMI: 20 were normal weight (BMI ≤ 25 kg/m(2)), 21 overweight (25.1 ≤ BMI ≤ 29.9 kg/ m(2)), and 14 obese (BMI ≥ 30 kg/m(2)). Each subject was given 300,000 IU of cholecalciferol orally during lunch. A fasting blood test was obtained before cholecalciferol loading and then 7, 30, and 90 days afterwards to measure serum 25OHD, 1,25 dihydroxyvitamin D [1,25 (OH)2D], parathyroid hormone (PTH), calcium (Ca), and phosphorus (P). Participants' absolute fat mass was measured using dual energy X-ray absorptiometry (DEXA). The fat mass of the normal weight subjects was significantly lower than that of the overweight, which in turn was lower than that of the obese participants. Serum 25OHD levels increased significantly in all groups, peaking 1 week after the cholecalciferol load. Peak serum 25OHD levels were lower the higher the individuals' BMI. After peaking, the 25OHD levels gradually decreased, following a significantly different trend in the three groups. The slope was similar for the overweight and obese, declining significantly more slowly than in the normal weight group. In the sample as a whole, there was a weakly significant negative correlation

Whole-body vibration exercise in postmenopausal osteoporosis

Directory of Open Access Journals (Sweden)

Magdalena Weber-Rajek

2015-01-01

Full Text Available The report of the World Health Organization (WHO of 2008 defines osteoporosis as a disease characterized by low bone mass and an increased risk of fracture. Postmenopausal osteoporosis is connected to the decrease in estrogens concentration as a result of malfunction of endocrine ovarian function. Low estrogens concentration causes increase in bone demineralization and results in osteoporosis. Physical activity, as a component of therapy of patients with osteoporosis, has been used for a long time now. One of the forms of safe physical activity is the vibration training. Training is to maintain a static position or execution of specific exercises involving the appropriate muscles on a vibrating platform, the mechanical vibrations are transmitted to the body of the patient. According to the piezoelectric theory, pressure induces bone formation in the electrical potential difference, which acts as a stimulant of the process of bone formation. Whole body vibration increases the level of growth hormone and testosterone in serum, preventing sarcopenia and osteoporosis. The aim of this study was to review the literature on vibration exercise in patients with postmenopausal osteoporosis based on the PubMed and Medline database. While searching the database, the following key words were used ‘postmenopausal osteoporosis’ and ‘whole-body vibration exercise’.

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

Adiponectin, a fat derived cytokine, is a potential independent contributor to bone mineral density (BMD); however, its action on bone metabolism in humans is still unclear. The aim of this study was to investigate the relationship of adiponectin with bone mass indices and bone metabolic markers in middle-aged post-menopausal women without diabetes. A random sample consisted of 81 post-menopausal women (age range 45-61 yr, osteopenic/osteoporotic no.=43) was studied. Lumbar-spine BMD (BMD(L2-L4)) and total-body bone mineral content (TBBMC) were measured with dual X-ray absorptiometry. Plasma levels of total and high-molecular weight (HMW) adiponectin, osteoprotegerin (OPG), soluble receptor activator of nuclear factor-κB ligand (sRANKL) and IGF-I were determined. No association was observed between total or HMW adiponectin and BMD(L2-L4) or TBBMC. On the contrary, adiponectin levels were positively associated with OPG levels (partial r=0.276, p=0.015) and negatively with IGF-I (partial r=-0.438, pfailed to show statistically significant association between circulating adiponectin levels and indices of bone mass in women during the postmenopausal period, we showed significant associations with OPG and IGF-I levels, suggesting an anabolic role of adiponectin, which may contribute in the understanding of the interplay between adipose tissue-derived hormones and bone metabolism. © 2012, Editrice Kurtis.

Abstract Background: It is increasingly being recognized that alterations of the GABAergic system are implicated in the pathophysiology of depression. This study aimed to explore in vivo gamma-aminobutyric acid (GABA) levels in the anterior cingulate cortex/medial prefrontal cortex (ACC/mPFC) and posterior-cingulate cortex (PCC) of postmenopausal women with depression using magnetic resonance spectroscopy (1H-MRS). Methods: Nineteen postmenopausal women with depression and thirteen healthy controls were enrolled in the study. All subjects underwent 1H-MRS of the ACC/mPFC and PCC using the “MEGA Point Resolved Spectroscopy Sequence” (MEGA-PRESS) technique. The severity of depression was assessed by 17-item Hamilton Depression Scale (HAMD). Quantification of MRS data was performed using Gannet program. Differences of GABA+ levels from patients and controls were tested using one-way analysis of variance. Spearman correlation coefficients were used to evaluate the linear associations between GABA+ levels and HAMD scores, as well as estrogen levels. Results: Significantly lower GABA+ levels were detected in the ACC/mPFC of postmenopausal women with depression compared to healthy controls (P = 0.002). No significant correlations were found between 17-HAMD/14-HAMA and GABA+ levels, either in ACC/mPFC (P = 0.486; r = 0.170/P = 0.814; r = −0.058) or PCC (P = 0.887; r = 0.035/ P = 0.987; r = −0.004) in the patients; there is also no significant correlation between GABA+ levels and estrogen levels in patients group (ACC/mPFC: P = 0.629, r = −0.018; PCC: P = 0.861, r = 0.043). Conclusion: Significantly lower GABA+ levels were found in the ACC/mPFC of postmenopausal women with depression, suggesting that the dysfunction of the GABAergic system may also be involved in the pathogenesis of depression in postmenopausal women.

Obesity is a risk factor for postmenopausal breast cancer incidence and premenopausal and postmenopausal breast cancer mortality, which may be explained by several metabolic and hormonal factors (sex hormones, insulin resistance, and inflammation) that are biologically related. Differential effects of dietary composition on weight loss and these metabolic factors may occur in insulin-sensitive vs. insulin-resistant obese women. To examine the effect of diet composition on weight loss and metabolic, hormonal and inflammatory factors in overweight/obese women stratified by insulin resistance status in a 1-year weight loss intervention. Nondiabetic women who were overweight/obese (n=245) were randomly assigned to a lower fat (20% energy), higher carbohydrate (65% energy) diet; a lower carbohydrate (45% energy), higher fat (35% energy) diet; or a walnut-rich (18% energy), higher fat (35% energy), lower carbohydrate (45% energy) diet. All groups lost weight at follow-up (Ploss of 9.2(1.1)% in lower fat, 6.5(0.9)% in lower carbohydrate, and 8.2(1.0)% in walnut-rich groups at 12months. The diet×time×insulin resistance status interaction was not statistically significant in the model for overall weight loss, although insulin sensitive women at 12months lost more weight in the lower fat vs. lower carbohydrate group (7.5kg vs. 4.3kg, P=0.06), and in the walnut-rich vs. lower carbohydrate group (8.1kg vs. 4.3kg, P=0.04). Sex hormone binding globulin increased within each group except in the lower carbohydrate group at 12months (Ploss depending on insulin resistance status. Prescribing walnuts is associated with weight loss comparable to a standard lower fat diet in a behavioral weight loss intervention. Weight loss itself may be the most critical factor for reducing the chronic inflammation associated with increased breast cancer risk and progression. Copyright © 2016. Published by Elsevier Inc.

The purpose of this study is to evaluate the signal intensity and size of anterior pituitary gland in postpartum women, and to compare with those of control group. In 34 postpartum women (18-43 years, mean: 27 years) and another 35 control nonpregnant women (20-29 years, mean: 24 years), midsagittal T1-weighted MR images were obtained. The signal intensity and height of the anterior pituitary gland were compared between the post-partum and normal control groups. In postpartum women, the signal intensity of the anterior pituitary gland relative to the pons was higher than that of the control group. Pituitary gland height of postpartum women was higher (5-11. 8mm, mean 8.18 ± 1.8mm) than that of control group (2-9mm, mean: 6.2 ± 1.7mm). It is concluded that the hyperintensity of the anterior pituitary gland on T1-weighted image is a normal finding in postpartum women, which is useful in differentiation from pituitary abnormality

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

Science.gov (United States)

2017-01-23

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

UI is a worldwide chronic condition among postmenopausal women. Little is known about the meaning of lived experiences of urinary incontinence of these women's viewpoints in their context. The aim of this study was to illuminate the experience of Muslim community-dwelling postmenopausal women who were living with urinary incontinence (UI). Seventeen women with UI (range: 52-68 years) who had experienced it for more than ten years were interviewed. A phenomenological hermeneutic method was used to analyze and interpret the interview texts. The women's experiences of living with urinary incontinence have been presented in terms of three main themes: disruption of normal functioning, self-imposed restriction, and feelings of despair. Disruption of normal functioning meant emotional, spiritual, physical, and daily life disruption. Self-imposed restriction meant suppression of delights and needs and avoidance of social interactions. Feelings of despair referred to predictions of a bad and dark future of living with urinary incontinence, ambiguity, and hopelessness. The meaning of living with UI has been considered a 'stain in life'. Health care providers should be familiar with the different manifestations of urinary incontinence for early diagnosis and prevention of the negative effects of this condition to improve quality of life. In addition, symbolic interactionism theory can help health care providers to understand the meaning of urinary incontinence for women. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

2010-04-01

The relationship between adiponectin and sex hormones with bone mineral density (BMD) and bone formation markers was investigated in postmenopausal women with subclinical hyperthyroidism (SCH). Seventy-five postmenopausal women were selected among the patients who participated in a health screening program in 2007. Thirty-seven control women with normal thyroid function were matched to 38 women with SCH by age, body mass index (BMI), and years since menopause (YSM). The associations between adiponectin and sex hormones with lumbar spine BMD and bone turnover markers were investigated. Adiponectin, testosterone (T; total and free forms), and thyroid-stimulating hormone were significantly different between the women with SCH and euthyroid. After adjusting for age, BMI, and YSM, free T (r = 0.351; P = 0.029) and estradiol (E2; r = -0.368; P = 0.024) had significant associations with bone alkaline phosphatase (B-ALP). Total T (r = 0.388; P = 0.021) and E2 (r = -0.376; P = 0.026) had significant associations with osteocalcin. However, there were no significant associations between adiponectin and sex hormones with the BMD levels in the SCH subjects. There were correlations between sex hormones with B-ALP and osteocalcin, but no associations between adiponectin and sex hormones with the lumbar spine BMD in postmenopausal SCH patients.

To determine the prevalence of normal weight obesity among multi-ethnic women in Peninsular Malaysia and examine its associations with cardiometabolic risks and lifestyle behaviours. This was a cross-sectional study involving women recruited via multi-stage sampling from six states in Malaysia. Anthropometric and body composition analysis were performed. Normal weight obese (NWO) was defined as normal body mass index for Asians and the highest tertile of % body fat (BF). Biochemical measurements included fasting lipid and blood glucose levels. Metabolic syndrome was diagnosed based on the Harmonization criteria. Participants completed self-reported questionnaires that included physical activity, smoking, alcohol consumption, fruit and vegetable intake and sleep duration. Body mass index, %BF, cardiometabolic risk factors, lifestyle behaviours. A total of 6854 women were recruited and the prevalence of NWO was 19.8% (95% CI: 17.3-22.5). NWO was more prevalent among the Indians and older women. NWO women had higher odds for abdominal obesity (OR: 2.64, 95% CI: 1.73-4.04), hypertriglyceridemia (2.51, 1.47-4.29) and hypertension (1.63, 1.15-2.31) compared to women with lower % body fat after adjusted for age and ethnicity. The prevalence of metabolic syndrome among NWO women was 5.4% (95% CI: 3.0-9.8). None of the lifestyle behaviours were significantly associated with NWO. Women with NWO had cardiometabolic abnormalities including abdominal obesity, dyslipidaemia and increased blood pressure. Health promotion efforts should include NWO women who may be oblivious of their deleterious health risks. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Chocolate has a reputation for contributing to weight gain due to its high fat, sugar and calorie content. However, the effect of varying concentrations of cocoa in chocolate on energy intake and appetite is not clear. To compare the acute effect of consuming an isocaloric dose of dark, milk and white chocolate on subsequent energy intake, appetite and mood in postmenopausal women. Fourteen healthy postmenopausal women (57.6 ± 4.8yr) attended an introductory session followed by three experimental trials performed in a counterbalanced order at a standardised time of day, each separated by one week. Ad libitum energy intake, perceived appetite, mood and appetite-related peptides were assessed in response to consumption of 80% cocoa [dark chocolate], 35% cocoa [milk chocolate] and cocoa butter [white chocolate] (2099 kJ), prepared from a single-origin cacao bean. Ad libitum energy intake was significantly lower following dark (1355 ± 750 kJ) compared with both milk (1693 ± 969 kJ; P = 0.008) and white (1842 ± 756 kJ; P = 0.001) chocolate consumption. Blood glucose and insulin concentrations were transiently elevated in response to white and milk chocolate consumption compared with the dark chocolate (P cocoa content chocolate (dark and milk) compared with white chocolate (P  0.05).

Osteoporosis is a disease associated with insulin resistant states such as central obesity, diabetes, and metabolic syndrome. Non-alcoholic fatty liver disease (NAFLD) is also increased in such conditions. However, little is known about whether osteoporosis and nonalcoholic fatty liver disease are etiologically related to each other or not. We examined whether bone mineral density (BMD) is associated with NAFLD in pre- and postmenopausal women. Four hundred eighty-one female subjects (216 premenopausal and 265 postmenopausal) were enrolled. Lumbar BMD was measured using dual-energy X-ray absorptiometry. Liver ultrasonography was done to check the severity of fatty liver. We excluded subjects with a secondary cause of liver disease. Blood pressure, lipid profile, fasting plasma glucose, alanine aminotransferase (ALT), aspartate aminotransferase, and body mass index were measured in every subject. Mean lumbar BMD was lower in subjects with NAFLD than those without NAFLD in postmenopausal women (0.98 ± 0.01 vs. 1.01 ± 0.02 g/cm², P = 0.046). Multiple correlation analysis revealed a significant association between mean lumbar BMD and NAFLD in postmenopausal subjects after adjusting for age, body mass index, ALT, smoking status, and alcohol consumption (β coefficient -0.066, 95% CI -0.105 to -0.027, P = 0.001). Even after adjusting the presence of metabolic syndrome, the significance was maintained (β coefficient -0.043, 95% CI -0.082 to -0.004, P = 0.031). Lumbar BMD is related with NAFLD in postmenopausal females. We suggest that postmenopausal women with NAFLD may have a higher risk of osteoporosis than those without.

Hemostasis in women is affected by changes of estrogen levels. The role of endogenous estrogens on risk of venous thromboembolism (VTE) remains unclear. The aim of this study was to investigate the importance of acquired and genetic risk factors for VTE in pre-and postmenopausal women. In a nationwide case-control study we included as cases 1470 women, 18 to 64years of age with a first time VTE. The 1590 controls were randomly selected and matched by age to the cases. Information on risk factors was obtained by interviews and DNA-analyses. We used unconditional logistic regression to calculate odds ratios (ORs) with 95% confidence intervals (CIs). The ORs were generally of similar magnitude in pre- and postmenopausal women. The highest risk was for the combination of surgery and cast (adjusted OR 54.12, 95% CI 16.62-176.19) in postmenopausal women. The adjusted OR for use of menopausal hormone therapy was 3.73 (95% CI 1.86-7.50) in premenopausal and 2.22 (95% CI 1.54-3.19) in postmenopausal women. Overweight was linked to an increased risk and exercise to a decreased risk, regardless of menopausal status. Menopausal status had only minor influence on the risk levels. Acquired transient risk factors conveyed the highest risks for VTE. Copyright © 2012 Elsevier Ltd. All rights reserved.

The stress hormone cortisol is vital to survival, and a disturbed circadian rhythm can be deleterious to health. However, little is known about cortisol levels in healthy children. The aim of this study was to examine cortisol levels in relation to body mass index (BMI), age and sex. Salivary samples were collected in early morning, late morning and evening, on four consecutive days, from 342 children aged 6-12 years using Salivette(®) tubes. Samples were analysed using a commercial enzyme immunoassay (EIA). School nurses measured the children's height and weight, and these measurements were used to calculate their BMI. The children displayed a circadian rhythm in cortisol secretion, with morning zeniths and evening nadirs. Average cortisol levels in early morning, late morning and evening were significantly lower in overweight and obese children than in their normal weight counterparts. Cortisol levels did not vary significantly with age or sex. Our findings may suggest cortisol suppression in overweight and obese children. We found no evidence that sex or age influences cortisol levels. These findings highlight the need for further research on the relationship between stress and obesity in children. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Protein-energy wasting (PEW) is prevalent in haemodialysis. Obesity is an independent risk factor of kidney insufficiency, but it is proposed to have beneficial roles in better outcomes in the final stage of disease. Better nutritional status and body reserves are among probable mechanisms, but direct examinations are limited. The present study aimed to investigate whether obese patients have preferable nutritional status compared to normal weight patients based on malnutrition inflammation score (MIS) and other PEW parameters in haemodialysis. This case-control study investigated 52 normal weight (18.5 < body mass index (BMI) < 25 kg/m 2 ) and 48 obese (BMI≥30 kg/m 2 ) patients on regular haemodialysis. PEW was assessed based on anthropometric and biochemical factors, recent weight changes, appetite, anorexia, dietary intake and MIS. Obese patients had better MIS compared with the normal weight group (P < 0.001), although varying degrees of wasting were prevalent among this group too (75% mild and 25% moderate wasting). The obese group had less significant weight loss (4.2 vs 8%) and anorexia and better appetite. However, a considerable percentage of patients in both groups showed muscle (94.6% of normal weight and 19.5% of obese) and peripheral fat tissue (89.2% of normal weight and 31.7% of obese) losses compared to the 50th percentile. Biochemical parameters were not significantly different between groups except for triglyceride (P = 0.001), transferrin and total iron-binding capacity (P = 0.028). MIS was significantly better in obese patients; however, both groups showed degrees of wasting based on MIS and other PEW parameters. Nutritional status of obese haemodialysis patients should be monitored regularly because of high risk of PEW like other BMI categories. © 2017 Dietitians Association of Australia.

A Complete Color Normalization Approach to Histopathology Images Using Color Cues Computed From Saturation-Weighted Statistics.

In digital histopathology, tasks of segmentation and disease diagnosis are achieved by quantitative analysis of image content. However, color variation in image samples makes it challenging to produce reliable results. This paper introduces a complete normalization scheme to address the problem of color variation in histopathology images jointly caused by inconsistent biopsy staining and nonstandard imaging condition. Method : Different from existing normalization methods that either address partial cause of color variation or lump them together, our method identifies causes of color variation based on a microscopic imaging model and addresses inconsistency in biopsy imaging and staining by an illuminant normalization module and a spectral normalization module, respectively. In evaluation, we use two public datasets that are representative of histopathology images commonly received in clinics to examine the proposed method from the aspects of robustness to system settings, performance consistency against achromatic pixels, and normalization effectiveness in terms of histological information preservation. As the saturation-weighted statistics proposed in this study generates stable and reliable color cues for stain normalization, our scheme is robust to system parameters and insensitive to image content and achromatic colors. Extensive experimentation suggests that our approach outperforms state-of-the-art normalization methods as the proposed method is the only approach that succeeds to preserve histological information after normalization. The proposed color normalization solution would be useful to mitigate effects of color variation in pathology images on subsequent quantitative analysis.

Full Text Available CONTEXT: The relationship between body size and breast cancer still remains controversial in considering menopausal status. OBJECTIVE: To evaluate the association of height, weight and weight changes with breast cancer in the city of Rio de Janeiro, Brazil. DESIGN: Case-control study. SETTING: National Cancer Institute (INCA, Rio de Janeiro, Brazil, and State University of Rio de Janeiro (UERJ. SAMPLE: 177 incident cases of invasive breast cancer admitted to the main hospital of INCA between May 1995 and February 1996, and 377 controls recruited from among female visitors to the same hospital. MAIN MEASUREMENTS: Height and weight were measured and information on maximum weight, weight at ages 18 and 30 years, and potential risk factors were ascertained by interview at the hospital. RESULTS: Height was not related to risk of breast cancer among both pre and postmenopausal women. Nevertheless, women in this study were shorter than in studies that have found a positive association. Premenopausal women in the upper quartile of recent body mass index (BMI and maximum BMI showed a reduced risk of breast cancer (P for trend <= 0.03. Weight loss between ages 18 and 30 years and from 18 years to present was also associated with breast cancer among premenopausal women. CONCLUSIONS: These findings may merely indicate the known association between leanness and breast cancer. Further studies should explore the role of weight loss on breast cancer risk.

Brain structural correlates of reward sensitivity and impulsivity in adolescents with normal and excess weight.

Directory of Open Access Journals (Sweden)

Laura Moreno-López

Full Text Available INTRODUCTION: Neuroscience evidence suggests that adolescent obesity is linked to brain dysfunctions associated with enhanced reward and somatosensory processing and reduced impulse control during food processing. Comparatively less is known about the role of more stable brain structural measures and their link to personality traits and neuropsychological factors on the presentation of adolescent obesity. Here we aimed to investigate regional brain anatomy in adolescents with excess weight vs. lean controls. We also aimed to contrast the associations between brain structure and personality and cognitive measures in both groups. METHODS: Fifty-two adolescents (16 with normal weight and 36 with excess weight were scanned using magnetic resonance imaging and completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ, the UPPS-P scale, and the Stroop task. Voxel-based morphometry (VBM was used to assess possible between-group differences in regional gray matter (GM and to measure the putative differences in the way reward and punishment sensitivity, impulsivity and inhibitory control relate to regional GM volumes, which were analyzed using both region of interest (ROI and whole brain analyses. The ROIs included areas involved in reward/somatosensory processing (striatum, somatosensory cortices and motivation/impulse control (hippocampus, prefrontal cortex. RESULTS: Excess weight adolescents showed increased GM volume in the right hippocampus. Voxel-wise volumes of the second somatosensory cortex (SII were correlated with reward sensitivity and positive urgency in lean controls, but this association was missed in excess weight adolescents. Moreover, Stroop performance correlated with dorsolateral prefrontal cortex volumes in controls but not in excess weight adolescents. CONCLUSION: Adolescents with excess weight have structural abnormalities in brain regions associated with somatosensory processing and motivation.

Aim of this retrospective study was to compare diagnostic accuracy of proposed automatic normalization method to quantify the relative cerebral blood volume (rCBV) with existing contra-lateral region of interest (ROI) based CBV normalization method for glioma grading using T1-weighted dynamic contrast enhanced MRI (DCE-MRI). Sixty patients with histologically confirmed gliomas were included in this study retrospectively. CBV maps were generated using T1-weighted DCE-MRI and are normalized by contralateral ROI based method (rCBV_contra), unaffected white matter (rCBV_WM) and unaffected gray matter (rCBV_GM), the latter two of these were generated automatically. An expert radiologist with >10years of experience in DCE-MRI and a non-expert with one year experience were used independently to measure rCBVs. Cutoff values for glioma grading were decided from ROC analysis. Agreement of histology with rCBV_WM, rCBV_GM and rCBV_contra respectively was studied using Kappa statistics and intra-class correlation coefficient (ICC). The diagnostic accuracy of glioma grading using the measured rCBV_contra by expert radiologist was found to be high (sensitivity=1.00, specificity=0.96, pnormalization method showed same percentage of agreement for both expert and non-expert user. rCBV_WM showed an agreement of 88.33% (kappa=0.76,pnormalization of CBV using the proposed method could provide better diagnostic accuracy compared to the manual contralateral based approach.

Full Text Available Sleep disorders are commonly observed among postmenopausal women, with negative effects on their quality of life. The search for complementary therapies for sleep disorders during postmenopausal period is of high importance, and acupuncture stands out as an appropriate possibility. The present review intended to systematically evaluate the available literature, compiling studies that have employed acupuncture as treatment to sleep disorders in postmenopausal women. A bibliographic search was performed in PubMed/Medline and Scopus. Articles which had acupuncture as intervention, sleep related measurements as outcomes, and postmenopausal women as target population were included and evaluated according to the Cochrane risk of bias tool and to the STRICTA guidelines. Out of 89 search results, 12 articles composed our final sample. A high heterogeneity was observed among these articles, which prevented us from performing a meta-analysis. Selected articles did not present high risk of bias and had a satisfactory compliance rate with STRICTA guidelines. In general, these studies presented improvements in sleep-related variables. Despite the overall positive effects, acupuncture still cannot be stated as a reliable treatment for sleep-related complaints, not due to inefficacy, but rather limited evidence. Nevertheless, results are promising and new comprehensive and controlled studies in the field are encouraged.

Obesity in the United States has increased dramatically during the past several decades. There is debate about optimum calorie balance for prevention of weight gain, and proponents of some low-carbohydrate diet regimens have suggested that the increasing obesity may be attributed, in part, to low-fat, high-carbohydrate diets. To report data on body weight in a long-term, low-fat diet trial for which the primary end points were breast and colorectal cancer and to examine the relationships between weight changes and changes in dietary components. Randomized intervention trial of 48,835 postmenopausal women in the United States who were of diverse backgrounds and ethnicities and participated in the Women's Health Initiative Dietary Modification Trial; 40% (19,541) were randomized to the intervention and 60% (29,294) to a control group. Study enrollment was between 1993 and 1998, and this analysis includes a mean follow-up of 7.5 years (through August 31, 2004). The intervention included group and individual sessions to promote a decrease in fat intake and increases in vegetable, fruit, and grain consumption and did not include weight loss or caloric restriction goals. The control group received diet-related education materials. Change in body weight from baseline to follow-up. Women in the intervention group lost weight in the first year (mean of 2.2 kg, Pfruit servings, and a nonsignificant trend toward weight loss occurred with increasing intake of fiber. A low-fat eating pattern does not result in weight gain in postmenopausal women. Clinical Trial Registration ClinicalTrials.gov, NCT00000611.

Bone turnover in postmenopausal osteoporosis

International Nuclear Information System (INIS)

Thomsen, K.

1988-02-01

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

To establish the possible role of hyperinsulinemia in the elevation of plasma beta-endorphin (beta-EP) levels observed in obese patients after an oral glucose load. Oral glucose tolerance test (OGTT) and euglycemic-hyperinsulinemic clamp. Two groups of six (age: 22-39 y, BMI: 30-48 kg/m2) and eight obese men (age: 18-37 y, BMI: 35-45 kg/m2), respectively, and five normal weight healthy men (age: 22-30 y, BMI 22-23 kg/m2). Glucose, insulin and beta-EP levels at baseline and every 30 min until 180 min during the OGTT; glucose, insulin, C-peptide and beta-EP concentrations at baseline and in steady state condition (i.e. during the last 30 min of insulin infusion) in the euglycemic-hyperinsulinemic clamp studies. In the six obese patients undergoing the OGTT a significant elevation of beta-EP plasma levels was observed between 60 and 90 min after glucose ingestion. In the clamp studies no significant differences in beta-EP plasma levels, blood glucose and serum insulin were observed between obese and normal weight subjects both at baseline and at steady state. A markedly diminished insulin sensitivity along with a lower inhibition of C-peptide during insulin infusion was observed in obese patients compared to control subjects. A rise in serum insulin levels unaccompanied by a concomitant increase in blood glucose concentration is unable to elicit a beta-EP response in obese patients.

Recent investigations have shown that panoramic radiography might be a useful tool in the early diagnosis of osteoporosis. In addition, bone turnover biochemical marker might be valuable in predicting osteoporosis and fracture risks in the elderly, especially in post-menopausal women. The aim of the present study was to evaluate the relationship among the radio morphometric indices of the mandible, biochemical markers of the bone turnover and hip bone mineral density in a group of post-menopausal women. Patients and Methods: Evaluations of mandibular cortical width, mandibular cortical index, panoramic index and alveolar crest resorption ration (M/M ration) were carried out on panoramic radiographs of 140 post-menopausal women with an age range of 44-82 years. Hip bone mineral density was measured by dual-energy X-ray absorptiometry method. Bone mineral density values were divided into three groups of normal (T score>-1.0), Osteopenic (T score, -2.5 to -1.0) and Osteoporotic (T score<-2.5). Serum alkaline phosphatase and 25(OH) D3 were measured. Results: A decrease in mandibular cortical width by 1 mm increases the likelihood of osteopenia or osteoporosis up to 40%, having taken into consideration the effect of menopause duration. A 1 mm decrease in mandibular cortical width increased the likelihood of moderate or severe erosion of the lower cortex of the mandible up to 28% by taking age into consideration. The results did not demonstrate a statistically significant relationship between bone turnover markers and mandibular radio morphometric indices. Conclusion: Panoramic radiography gives sufficient information to make an early diagnosis regarding osteoporosis in post-menopausal women. Panoramic radiographs may be valuable in the prevention of osteoporotic fractures in elderly women.

To investigate the relationship between visceral fat and carotid IMT (intima media thickness) in Mexican postmenopausal women. In 71 postmenopausal women divided in two groups: group 1, IMT > 1 mm and group 2, IMT ≤ 1 mm, blood pressure, body mass index (BMI), waist hip ratio (WHR), visceral and subcutaneous fats and carotid IMT were analyzed. Descriptive statistics were used and the comparison among those with abnormal and normal IMT was carried out using Mann-Whitney U test; also Spearman's correlation analysis was done. When comparing group 1 (n = 9, 12.7%) with group 2 (n = 62, 87.3%), it was found that the subcutaneous fat, visceral fat and systolic blood pressure were significantly greater in group 1 (p < 0.018, p < 0.001 and p < 0.006, respectively), and also in this group there was a correlation between BMI and subcutaneous fat (ρ = 0.686, p < 0.041) and between visceral fat and the systolic blood pressure (ρ = 0.712, p < 0.031). In group 2, there was a correlation between IMT and diastolic blood pressure (ρ = 0.251, p < 0.049). Subcutaneous and visceral fat have an unfavorable effect in the carotid IMT and in blood pressure.

Isolated fallopian tube torsion after menopause is a rare condition. Here we report the second case of isolated fallopian tube torsion in a post-menopausal woman. A 55-year-old post-menopausal woman presented with right lower abdominal pain. Sonography depicted a simple cystic mass adjacent to the right uterine border. Laparatomy revealed torsion of the right fallopian tube together with a paraovarian cyst. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Histopathological examination revealed a simple paraovarian cyst with severe congestion, necrosis and hemorrhage. Tubal torsion should be considered in the differential diagnosis of acute lower abdominal pain, even in post-menopausal women.

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

Menopausal hot flashes are considered largely a quality-of-life issue. However, emerging research also links hot flashes to cardiovascular risk. In some investigations, this risk is particularly apparent among women using hormone therapy. The aim of this study was to determine whether a longer history of reported hot flashes over the study period was associated with greater aortic and coronary artery calcification. Interactions with hormone therapy use were examined in an exploratory fashion. Participants included 302 women participating in the Healthy Women Study, a longitudinal study of cardiovascular risk during perimenopause and postmenopause, which was initiated in 1983. Hot flashes (any/none) were assessed when women were 1, 2, 5, and 8 years postmenopausal. Electron beam tomography measures of coronary artery calcification and aortic calcification were completed in 1997-2004. Associations between the number of visits with report of hot flashes, divided by the number of visits attended, and aortic or coronary artery calcification (transformed) were examined in linear regression models. Interactions by hormone therapy use were evaluated. Among women using hormone therapy, a longer history of reported hot flashes was associated with increased aortic calcification, controlling for traditional cardiovascular risk factors (b = 2.87, SE = 1.21, P history of hot flashes and coronary artery calcification. Among postmenopausal women using hormone therapy, a longer history of reported hot flashes measured prospectively was associated with increased aortic calcification, controlling for traditional cardiovascular risk factors. Hot flashes may signal adverse cardiovascular changes among certain postmenopausal women.

Full Text Available Introduction Schizophrenia patients are at greater risk of obesity, diabetes mellitus (DM, lipid abnormalities and cardiovascular disorders. The metabolic complications in patients are associated with several risk factors: family history of DM, lifestyle, smoking, dietary habits, physical inactivity, but also with antipsychotic medication. In literature, most publications have been focused on the effects of the second generation antipsychotics (SGA on glucose metabolism. However, less attention has been paid to abnormality in glucoregulation, patients with schizophrenia treated with the first generation antipsychotics (FGA. Objective The present study evaluated glucose metabolism in normal weight schizophrenia patients treated with FGA. METHOD The cross-sectional study included 18 patients (FGA treated and 20 healthy controls with neither group differences in sex distribution, age, nor in BMI. Inclusion criteria were normal BMI (20-25 kg/m2. The glucose levels, insulin levels and growth hormone levels during oral glucose tolerance test (OGTT were measured. Results Fasting glucose and insulin levels did not differ significantly between groups. Groups differed in OGTT glucose and insulin peak and area under curve (AUC, level of significance p<0.05 (patients vs. controls: glucose peak 8.3±0.4 vs.6.9±0.5 mmol/l, glucose AUC 758±28 vs. 640±36 mU/l/120 min; insulin peak in patients 92.7±15.6 mU/l; insulin AUC 6060±1016 mU/l/120 min, insulin peak in controls 47.9±6.5 mU/l; insulin AUC 2597±256 mU/l/120 min. Conclusion Patients with schizophrenia, although with normal body mass index, are at high risk of abnormal glucose regulation. Not only SGA increase the risk of impaired glucoregulation and metabolic syndrome, but this may also be due to FGA or schizophrenia per se. .

The aim of the present study was to investigate the health risks of excess body weight in the light of its protective effects on bone fragility. Femoral neck and lumbar spine dual X-ray absorptiometry was performed for 1970 Finnish women with a mean baseline age of 58.8 years (range 53.1-65.7 years) in 1994 and 2004. Women were categorized according to baseline BMI into normal obese ≥30 kg/m(2). Weight change (kg) was categorized into tertiles. Co-morbidities, not allowed to be present at baseline, was based on self-reports. Osteoporosis was defined as femoral neck or spinal (L2-L4) T-score Obesity (Ob) and overweight (Ow) were related with higher 10-year risk of hypertension (OR=2.6 (Ob)/OR=1.7 (Ow), posteoporosis (OR=0.13/OR=0.28, pobese women the absolute risk increase of hypertension was 17%, of diabetes 12%, and absolute risk reduction of osteoporosis 14% in comparison to BMI <25 kg/m(2). Health related risks of high BMI outweigh its protective effects on bone. Weight gain increases the risk hypertension and breast cancer. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.
