[Lipid status and oxidative stress in menopausal women with obstructive apnea syndrome]

AIM

to assess lipid profile, lipid peroxidation and antioxidant system parameters in peri - and postmenopausal women with obstructive sleep apnea syndrome (OSAS).

MATERIALS AND METHODS

37 perimenopausal women and 43 postmenopausal ones were examined. OSAS diagnosis was made on the basis of the clinical picture and the polysomnography results. In perimenopause, the main group consisted of 18 women, in postmenopausal women - 17. All comparison groups are comparable by age and body mass index. Lipid profile, lipid peroxidation and antioxidant system parameters by spectrophotometric methods were determined. Non - parametric criteria were used to analyze the group differences for the independent samples.

RESULTS AND DISCUSSION

The increase of total cholesterol (TC) and low - density lipoprotein cholesterol (LDL-C) levels were observed in perimenopausal women with OSAS as compared to control. The increase of TC, triacylglycerol (TG), LDL-C, very - low - density lipoprotein cholesterol (VLDL-C) levels and decrease of high - density lipoprotein cholesterol (HDL-D) level were found in postmenopausal women with OSAS as compared to control. Accumulation of ketodienes and conjugated trienes in perimenopausal women with OSAS and thiobarbituric acid reactants with a decrease of total antioxidant activity of blood serum in postmenopausal women with OSAS as compared to control was observed. Moreover, postmenopausal women with OSAS have a higher lipid peroxidation substrates and diene conjugates levels with a lower α-tocopherol level and total antioxidant activity compared with perimenopausal patients.The integral indicator of oxidative stress assessment indicates an imbalance in the lipid peroxidation and antioxidant system in menopausal women with OSAS.

CONCLUSION

The results obtained indicate a violation of lipid metabolism and the development of oxidative stress in patients with OSAS. This is most pronounced in the postmenopause due to the aggravation of the pathological condition.

Concordance between the Hysteroscopic Diagnosis of Endometrial Hyperplasia and Histopathological Examination

The goal of this paper is to assess the concordance between the clinical diagnosis of Endometrial Hyperplasia (EH), suspected by senior gynecologists throughout outpatient office hysteroscopy, and the results from histopathological examination, in order to evaluate hysteroscopic accuracy for EH. A prospective cohort study was done at a Tertiary University Hospital. From January to December 2018, we enrolled women with the following criteria: abnormal uterine bleeding in post-menopause and endometrial thickening in pre-or post-menopause. Patients underwent office hysteroscopy with a 5 mm continuous-flow hysteroscope, and endometrial biopsies were taken using miniaturized instruments. Senior operators had to foresee histopathological diagnosis using a questionnaire. Histopathological examination was conducted to confirm the diagnosis. This study was approved by the local ethical and registered in the ClinicalTrials.gov registry (ID no. NCT03917147). In 424 cases, 283 clinical diagnoses of EH were determined by senior surgeons. A histopathological diagnosis was then confirmed in 165 cases (58.3%; p = 0.0001). Furthermore, 14 endometrial carcinoma and atypical hyperplasia were found. The sensitivity, positive predictive value, and negative predictive values for EH were, respectively, 90.4, 58.4, and 86.6%. Subdivided by clinical indication, the sensitivity was higher in patients with post-menopause endometrial thickening. The diagnostic accuracy of office hysteroscopy in the diagnosis and prediction of endometrial hyperplasia was high. Senior operators could foresee EHs in more than half the cases.

Salivary calcium as a diagnostic tool for screening of osteoporosis in postmenopausal women

Background

Women's health undergoes physiological, pathological and psychological changes after menopause. Reduced estrogen levels have been implicated in the pathogenesis of osteoporosis in postmenopausal women. Estrogen is also known to affect the salivary gland functions. To understand the association between serum estrogen, osteoporosis and salivary calcium, the present cross-sectional study was undertaken.

Aim

The aim of this study is to determine salivary calcium levels and its use for the diagnosis of osteoporosis in postmenopausal women.

Methodology

Ninety individuals divided into three groups of healthy controls, pregnant women and postmenopausal women were selected. Serum estrogen, salivary calcium and bone mineral density (BMD) at the heel region were estimated. Statistical analysis using the Mann-Whitney U-test was done to compare the results within the groups.

Results

Mean estrogen levels were 115.8 ± 80.18 pg/mmol in control group, 7729.4 ± 907.6 pg/mmol in pregnant group and 51.2 ± 74.51 pg/mmol in postmenopausal group, respectively. The mean salivary calcium in control, pregnant and postmenopausal groups was 3.12 ± 0.63, 3.19 ± 0.62 and 7.12 ± 0.79 μg/dl, respectively. Paired comparison within the groups showed high statistical significance (P = 0.0000) in the salivary calcium levels. The mean BMD of -2.3 (standard deviation [SD] ± 0.83) in the postmenopausal group was significantly lower than -0.6 (SD ± 0.99) and -0.2 (SD ± 1.42) of pregnant and control groups, respectively.

Conclusion

A negative correlation was found between estrogen and bone density. A significant difference in salivary calcium was noted in the study groups, highlighting the role of salivary calcium in the detection of early bone changes in postmenopausal women.

The effect of vulvovaginal atrophy on women's quality of life from an Italian cohort of the EVES study

Vulvovaginal atrophy (VVA) has an impact on the quality of life (QoL) of women. This post hoc analysis of the EVES study provides an overview of the QoL in postmenopausal Italian women in relation with VVA severity. We included 1066 women attending menopause/gynaecologic centres. A face-to-face survey (including QoL and sexual life questionnaires), joining an objective gynaecological examination to confirm VVA, were performed. The 65.5% of the participants presented severe vaginal, vulvar and/or urinary symptoms; an 86.9% had an objective confirmed VVA. Women with severe symptoms presented with significantly worse QoL scores than the women without. We found there were moderately significant correlations between vaginal and vulvar symptoms' severity and lower overall DIVA QoL scores (p<.0005, in both cases). Women with a confirmed VVA presented worse QoL scores than women without confirmation. Our data suggest a clear relationship between VVA severity and a decrease in QoL in postmenopausal Italian women.IMPACT STATEMENTWhat is already known on this subject? Vulvovaginal atrophy (VVA) appears as a common chronic disorder in postmenopausal women that, as soon as the oestrogen levels decrease, becomes a severe condition affecting their quality of life (QoL).What do the results of this study add? We provide new insight about QoL related to VVA severity in Italian postmenopausal women. Our local data demonstrates that QoL in Italian women suffering from menopause is directly related to the severity of vaginal and vulvar symptoms. The same correlation exists for urinary symptoms. QoL is also reduced in patients with an objectively confirmed VVA diagnosis.What are the implications of these findings for clinical practice and/or further research? The implications of our findings involve the need for a better management, not only of the physical aspects of VVA, but also of the non-physical dimensions. Clinicians should ask for the impact of VVA on QoL aspects, making postmenopausal women aware about the possible affected spheres. Medical personnel should conduct future campaigns in the Italian general population, not only in those asking for medical help, to make all women conscious about this silent disorder affecting physical and non-physical dimensions and in order to treat it at early stages.

Circulating sex hormone levels and colorectal cancer risk in Japanese postmenopausal women: The JPHC nested case-control study

Previous epidemiological studies evaluated endogenous sex hormone levels and colorectal cancer (CRC) risk have yielded inconsistent results. Also, it is unknown if consumption of dietary isoflavones may influence the endogenous sex hormones and CRC relationships. We conducted a nested case-control study within the JPHC Study Cohort II wherein 11,644 women provided blood samples at the 5-year follow-up survey. We selected two matched controls for each case from the cohort (185 CRC cases and 361 controls). Multivariable conditional logistic regression was used to estimate odds ratios (ORs), 95% confidence intervals (CIs) for the association between circulating sex hormone levels and CRC risk. Comparing extreme tertiles, circulating testosterone levels were positively associated with CRC risk (OR = 2.10, 95% CI = 1.11-3.99, p for trend = 0.03). Levels of estradiol, SHBG, and progesterone were not associated with CRC risk. In a subgroup analysis by dietary isoflavone intake, SHBG levels were positively associated with CRC risk among those with low total isoflavone intake (p for trend = 0.03), with a statistically nonsignificant inverse association among those with high total isoflavone intake (p for trend = 0.22; p for interaction = 0.002). Endogenous levels of testosterone were positively associated with CRC among postmenopausal women. The association of endogenous SHBG with CRC development may be altered by the level of dietary isoflavone intake.

Associations of serum sex hormone binding globulin with bone mineral densities and higher 10-year probability of fractures in postmenopausal women with type 2 diabetes mellitus

Background

Postmenopause and type 2 diabetes mellitus (T2DM) are associated with higher fracture risk. Sex hormones are important in maintaining woman skeleton health. The relationships of sex hormone(s) with bone mineral density (BMD) and fracture risk are still unclear in diabetic-postmenopausal women. This study aimed to investigate the relationships of sex hormones with BMDs and fracture risk in postmenopausal women with T2DM.

Methods

Two hundred and fourteen postmenopausal women with T2DM were included. BMDs at lumbar spine (L2-4), femoral neck (FN) and total hip (TH) were measured by dual-energy X-ray absorptiometry (DXA). The 10-year probability of fractures was accessed by modified fracture risk algorithm (FRAX) tool. Serum concentrations of sex hormones were measured.

Results

Sex hormone binding globulin (SHBG) was a determinant of BMDs at L2-4 (β=-0.199, P<0.05), TH (β=-0.233, P<0.05), major osteoporotic fracture (MOF) (β=0.253, P<0.001) and hip fracture (HF) (β=0.262, P<0.001). Per SD increase in SHBG caused a 2% increase in the risk of osteoporosis/osteopenia. SHBG in quartile-4 was associated with 4.21 higher risk of osteoporosis/osteopenia compared with SHBG in quartile-1.

Conclusions

In postmenopausal women with T2DM, higher serum SHBG tended to be associated with lower BMDs, and increased the risk of osteoporosis/osteopenia and the fracture risk.

Ospemifene versus local estrogen: adherence and costs in postmenopausal dyspareunia

Aim: Objective was to compare adherence and persistence, as well as direct healthcare costs and utilization, of ospemifene to available local estrogen therapies (LETs). Patients & methods: This retrospective database study used integrated medical and pharmacy claims data from the IQVIA Real-World Data Adjudicated Claims - US Database. Results: Ospemifene patients had significantly greater adherence and persistence compared with the other nonring LETs. Ospemifene had the lowest mean outpatient costs of any of the LET cohorts, including the estradiol vaginal ring. Total all-cause healthcare costs were also significantly less for ospemifene patients compared with all other LETs.

[Nonspecific parameters of the immune inflammatory response as a link in the pathogenesis of remodeling of the vascular wall and destruction of bone tissue in women with arterial hypertension in postmenopausal women.]

Recently, they increasingly began to pay attention to the role of a nonspecific immune-inflammatory vascular response as a link in general pathogenetic mechanisms with a change in the elastic properties of arteries and phenomena of destructive bone changes, which at the subclinical level is of great importance for the prevention of the development of socially significant diseases. A total of 104 patients were examined (mean age 57.45 years), which were divided into three groups. The first group included 39 healthy women, the second group included 30 patients with hypertension and osteopenia, and the third group included 35 women with hypertension and osteoporosis. The analysis of markers of the immune inflammatory response, endothelial dysfunction, hormonal and mineral-vitamin status parameters was conducted against the background of the study of parameters of daily monitoring of arterial pressure, study of parameters of vascular wall stiffness and densitometry to clarify the predictors of cardiovascular and degenerative bone changes in postmenopausal women. A significant increase in the concentration of HF-CRP, the level of homocystemine, IL-8, parathyroid hormone, against the background of a significant decrease in the level of estrogen, progesterone, testosterone, with a persistent tendency to increase in total cholesterol, atherogenic lipid fractions, myeloperoxidase, endothelin-1 and decrease was recorded calcitonin, total and ionized calcium, with a significantly minimal value of vitamin D in the 3rd group of patients. The risks of development and progression of bone destructive changes were calculated using the logistic regression method for the group of AH with osteopenia and osteoporosis. Thus, for patients with hypertension and osteopenia, a significantly significant parameter associated with the risk of developing osteoporosis was an indicator of the velocity of the pulse wave, an increase in the level of which exceeds 12.05 m/s is associated with an increased risk of developing osteoporosis by 3.8 times. Increased levels of pro-inflammatory parameters, IL-6 and 8, TNF-α, HB-SRB, parathyroid hormone and reduced levels of progesterone and IL10, took the most active part in aggravating the degree of available bone tissue destruction. Timely specialized multidirectional study of biochemical and instrumental parameters (in particular, the study of the speed of the pulse wave and densitometry) can be the basis for the development of personalized prevention and treatment tactics for women in order to prevent socially dangerous cardiovascular and bone complications.

Correlations between the Peptide Hormone Ghrelin and Proinflammatory Cytokines in Experimental Periodontitis Models of Female Rats at Different Stages of the Life Cycle

OBJECTIVE

The aim of this study was to examine the correlations between the levels of ghrelin and inflammatory and bone metabolism markers in rats with periodontitis.

DESIGN

Thirty female Wistar rats (6 trial rats and 4 control rats in each group) were divided into pubertal, adult and postmenopausal groups. Periodontitis was induced by ligatures. On the 21 st day, blood was collected and all rats were then sacrificed. The levels of osteocalcin, osteoprotegerin, alkaline phosphatase, tumour necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β), acylated ghrelin, total ghrelin and soluble receptor activator of nuclear factor-kB ligands in the blood samples were measured using enzyme-linked immunosorbent assays. The jaws were decalcified in a Tris-EDTA solution and embedded in paraffin and 4-5 μm sections were cut for IL-β, TNF -α and ghrelin staining.

RESULTS

Significantly higher serum alkaline phosphatase levels were detected in the trial rats in the pubertal group than in the control rats (p = 0.033). In the postmenopausal group, ghrelin levels positively correlated with interleukin 1 beta levels (r = 0.708, p < 0.05). Among all trial rats, the postmenopausal group exhibited significantly higher levels of acylated ghrelin than the other groups (p = 0.001). Significantly higher osteoprotegerin levels were observed in the control rats than in the trial rats in the postmenopausal group (p = 0.012). Inflammation scores were significantly higher in adult trial rats than in controls (p = 0.024); significantly higher TNF-α levels were detected in postmenopausal experimental rats than in the adult experimental group (p = 0.025).

CONCLUSIONS

We concluded that total ghrelin levels in serum only correlated with IL-β levels in postmenopausal rats.

Postmenopausal craniofacial hyperhidrosis treated with botulinum toxin type B

Hyperhidrosis can seriously impair patients' quality of life. Medical history, including heredity and hyperhidrosis during youth, as well as current age and time elapsed since menopause, is important to consider when distinguishing between postmenopausal hyperhidrosis and vasomotor symptoms to enable adequate treatment. This report concerns a subgroup of eight postmenopausal patients participating in a randomized controlled trial regarding botulinum toxin (Btx) type B treatment in craniofacial hyperhidrosis. Even though the sample size is small and the enrolment is not yet completed, the promising data collected hitherto are interesting to present in advance because this subtype of craniofacial hyperhidrosis is often underrecognized and challenging to treat. Patients were randomized to receive Btx type B or placebo. Measurements were performed before treatment and 3 ± 1 weeks after. The Dermatology Life Quality Index (DLQI) score was improved for all patients after Btx type B treatment (n = 3) with a median decrease of 9 points (90% median improvement). The placebo group (n = 5) had a median increase of 2 points (-18% median decline). When the same group (n = 5) received Btx type B (open) the DLQI score decreased with a median of 7 points compared with baseline (91% median improvement). Treatment-related adverse events were temporary and did not prevent improvement of life quality. Furthermore, background data evaluation uncovered interesting findings regarding vasomotor symptoms in relation to postmenopausal hyperhidrosis. In conclusion, the results indicated that Btx type B seems to be a safe and effective treatment in postmenopausal craniofacial hyperhidrosis. Further research is encouraged.

Dietary intake of isoflavones is associated with a lower prevalence of subclinical cardiovascular disease in postmenopausal women: cross-sectional study

BACKGROUND

Menopause has been associated with an increased risk of cardiovascular disease. It has been shown that isoflavones protect vascular endothelial cells against induced oxidative stress injury. Therefore, the present study aimed to investigate the association between the dietary intake of isoflavones and the presence of subclinical cardiovascular disease (CVD) in postmenopausal women.

METHODS

Ninety-six postmenopausal women [mean (SD) age 55.2 (4.9) years, body mass index (BMI) 27.2 (4.6) kg m^-2 ] completed the study protocol. Habitual physical activity was assessed using a digital pedometer, resting metabolic rate was measured by indirect calorimetry and dietary intake was assessed via a validated food frequency questionnaire. Subclinical CVD was defined as carotid artery intima-media thickness (C-IMT) >0.9 mm and/or the presence of one or more atherosclerotic plaques in any of the studied segments.

RESULTS

Mean (SD) C-IMT was 0.74 (0.2) mm, 25% of participants were found to have atherosclerotic plaques and the prevalence of subclinical CVD was 35%. Participants with subclinical CVD were more likely to consume less selenium, magnesium, folate and isoflavones, even after adjusting for total energy intake. A multivariate-adjusted regression model showed that a BMI >27 kg m^-2 was associated with 90% higher risk of having ≥1 plaque and/or C-IMT >0.9 mm (P = 0.017). Higher oestradiol levels (P = 0.004) and isoflavone intake (P = 0.021) were independently associated with a lower risk of having subclinical CVD.

CONCLUSIONS

In the present study, we observed that a higher isoflavone dietary intake was associated with a lower risk of subclinical CVD in postmenopausal women, independent of BMI and endogenous oestradiol levels.

Association between non-HDL-C/HDL-C ratio and carotid atherosclerosis in postmenopausal middle-aged women

Background: A novel lipid relation, the non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (non-HDL-C/HDL-C) ratio gathers information on all atherogenic and antiatherogenic particles on a single date. The relationship between this lipid marker and the presence of carotid atherosclerotic plaque (CAP) in postmenopausal women is unknown. Methods: Postmenopausal women in primary prevention up to 70 years of age were recruited. Association between the non-HDL-C/HDL-C ratio and presence of CAP, assessed by ultrasonography, was analyzed. Receiver operating characteristic (ROC) curve analysis was performed. Results: A total of 440 females with a mean age of 58.1 ± 5.3 years were recruited. The mean non-HDL-C/HDL ratio was 3.1 ± 1.2 and 28.2% of woman had CAP. A positive relationship was seen between quintiles of the non-HDL-C/HDL-C ratio and prevalence of CAP (p < 0.001). Regardless of other risk factors, women with higher non-HDL-C/HDL-C ratios had a greater chance of having CAP (odds ratio 1.30, 95% confidence interval: 1.07-1.58, p = 0.009). In the ROC curve analysis, the area under the curve of the non-HDL-C/HDL ratio for detecting CAP was 0.703 (95% confidence interval: 0.640-0.765) and the optimal cut-off point was 3.0 (Youden index 0.395). Conclusion: The present study suggests that the non-HDL-C/HDL-C ratio might be a strong marker for predicting the risk of CAP in postmenopausal women.

Diagnostic accuracy of saline contrast sonohysterography in detecting endometrial polyps in women with postmenopausal bleeding: systematic review and meta-analysis

OBJECTIVE

In women with postmenopausal bleeding, endometrial polyps are a frequent finding and the risk of a focal (pre)malignancy in a polyp is up to 6%. Because of this reported risk, the detection of polyps in these women, preferably by a minimally invasive method, is important. The aim of this systematic review was to assess the accuracy of saline contrast sonohysterography (SCSH) for diagnosis of endometrial polyps in women with postmenopausal bleeding.

METHODS

In August 2018, an electronic search was performed of MEDLINE, EMBASE and Web of Science databases to identify all diagnostic studies in which SCSH was used to detect endometrial polyps in postmenopausal women. Studies were included if SCSH was performed to detect endometrial polyps in women with postmenopausal bleeding and if detection of a polyp on hysteroscopy or diagnosis on histopathology was used as a reference standard. Two reviewers assessed methodological quality using the quality assessment of diagnostic accuracy studies (QUADAS-2) tool. Two separate analyses were performed for each reference standard. Pooled sensitivity and specificity were calculated using the hierarchical summary receiver-operating characteristics (HSROC) model and HSROC curves were plotted.

RESULTS

After selection and quality assessment, five studies were included. Using 'polyps diagnosed with histopathology' as the reference standard, the pooled sensitivity of SCSH was 86.5% (95% CI, 63.6-100%) and the pooled specificity was 91.1% (95% CI, 63.2-100%). Using 'polyps seen on hysteroscopy' as the reference standard, the pooled sensitivity of SCSH was 85.1% (95% CI, 66.9-100%) and the pooled specificity was 84.5% (95% CI, 68.1-100%). Excluding the one study that included women in whom the SCSH examination was reported to be suboptimal, the pooled sensitivity increased to 90.7% (95% CI, 72.8-100%) using hysteroscopy as the reference standard. The sensitivity of hysteroscopy to detect polyps, as reported in two studies, was 81-98%.

CONCLUSIONS

Provided that the SCSH examination is of optimal quality, it can be considered as a method to stratify women with postmenopausal bleeding for further diagnostic workup and treatment with hysteroscopy. In women without suspicion of a polypoid lesion on SCSH, and with a benign endometrial sample, expectant management should be considered. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Artificial neural network optimizes self-examination of osteoporosis risk in women

Objective

This study aimed to investigate the application of an artificial neural network (ANN) in optimizing the Osteoporosis Self-Assessment Tool for Asians (OSTA) score.

Methods

OSTA score was calculated for each female participant that underwent dual-energy X-ray absorptiometry examination in two hospitals (one in each of two Chinese cities, Harbin and Ningbo). An ANN model was built using age and weight as input and femoral neck T-score as output. Osteoporosis risk screening by joint application of ANN and OSTA score was evaluated by receiver operating characteristic curve analysis.

Results

Nearly 90% of women with dual-energy X-ray absorptiometry-determined femoral neck osteoporosis were ≥60 years old. The ANN with age and weight as input and OSTA score both identified osteoporosis, with respective accuracy rates of 78.8% and 78.3%. However, both methods failed to identify osteoporosis in women < 60 years old. Compared with OSTA score alone, combined use of the two tools increased the rate of osteoporosis recognition among women > 80 years old.

Conclusions

OSTA score-mediated osteoporosis risk screening should be restricted to women ≥60 years old. Joint application of ANN and OSTA improved osteoporosis risk screening among Chinese women > 80 years old.

[Migraine in women: clinical and therapeutical aspects]

Migraine is one of the most common neurological disorders, affecting women. Physiological changes in the hormonal status can modulate the functional status of pain and analgesic systems of the brain and, by involving different pathophysiological mechanisms, change the course of migraine. In addition to an analysis of epidemiological data, the review provides current views on the clinical features of the disease in women population at different periods of life, particular attention was focused on menstrual migraine. It has certain features, such as acute and long attacks and treatment difficulties. One of main issues is the use of oral contraceptives in women with migraine according to the ratio of potential benefit to cardiovascular risk. The problems of treatment headaches in pregnant and breastfeeding women are also considered. An influence of migraine on the course and outcome of pregnancy was shown. The authors analysed the results of the studies on the course of migraine during perimenopause and postmenopause and recommendations for women with migraine attacks and climacteric syndrome. The data presented in the review are useful for clinicians, because this information represents new views on pathogenetic mechanisms, clinical features and treatment of migraine in women.

The Relation Between Metabolic Syndrome and Its Components with Breast Density in Postmenopausal Women

Background: Metabolic syndrome (MetS) could lead to an increase in fatty tissue that could be seen as a radiolucent image depicting breast density (BD) by a mammogram. We aimed to investigate the association between MetS and its separate components with BD among naturally postmenopausal women. Materials and Methods: Data of 494 postmenopausal patients who were admitted to our outpatient clinic between December 2012 and July 2015 were retrospectively reviewed. A total of 279 patients were in the without MetS group and 215 patients were in the with MetS group. Average BD percentage of the left and right breasts were measured. Basic characteristics, laboratory, and mammography results between the without MetS and the with MetS groups were compared. Results: The mean age of the patients was 53.20 ± 6.67 years in the without MetS group and 55.41 ± 6.56 years in the with MetS group. There were 219 (78.5%) patients in the without MetS group and 187 (86.9%) patients in the with MetS group with lower BD. The without MetS group had significantly higher BD scores than those patients in the with MetS group (P = 0.02). In correlation analysis, there was a negative correlation between fasting plasma glucose (FPG), systolic and diastolic blood pressures, waist circumference (WC), and BD scores. However, there was a positive correlation between high-density lipoprotein (HDL) and BD score (P = 0.046). In multivariate logistic regression analysis, it is found that lower body mass index (BMI) and parity were significantly associated with higher BD (P = 0.002 and P = 0.001; respectively). Conclusion: The lower BMI and parity may be associated with higher BD in postmenopausal women. In addition, higher HDL and lower FPG, blood pressure, triglyceride, and WC may be correlated with higher BD.

Effects of Parity and Breastfeeding Duration on Bone Density in Postmenopausal Women

PURPOSE

This study aimed to identify the effect of parity and breastfeeding duration and the occurrence of lumbar vertebral and femoral neck osteoporosis in Korean postmenopausal women.

METHODS

This study analyzed the data of 1,770 women based on the 2010-2011 results of the Korea National Health and Nutrition Examination Survey. Extracted data concerning bone density included variables known to be associated with osteoporosis. Complex sample multivariate logistic regression analysis was conducted to determine whether parity and breastfeeding duration were associated with osteoporosis in postmenopausal women.

RESULTS

Parity was not associated with postmenopausal osteoporosis in the femoral neck or lumbar vertebrae; however, the risk of femoral neck osteopenia was significantly higher in women with a history of 12-24 months of breastfeeding than in women who breastfed for less than 12 months (odds ratio = 2.12, 95% confidence interval = 1.07-4.21). In women who breastfed for 24 months or longer, the risk of lumbar vertebral osteoporosis was significantly higher than in those who breastfed for less than 12 months (odds ratio = 2.73, 95% confidence interval = 1.18-6.32).

CONCLUSION

Breastfeeding duration may affect the occurrence of lumbar vertebral or femoral neck osteopenia or osteoporosis. Therefore, women who breastfeed for one year or more require education on the risk of bone loss and the need for preventive measures such as adequate calcium intake and physical exercise.

Risk factors related to acupuncture response in postmenopausal women with stress urinary incontinence: Secondary analysis of a randomized controlled trial

Postmenopausal women are at a higher risk of stress urinary incontinence (SUI). In a previous trial, electroacupuncture (EA) was shown to be an effective treatment for women with SUI. Here we present a secondary analysis to investigate the specific factors associated with response to acupuncture therapy among postmenopausal women with SUI.We conducted secondary analysis of data from a multicenter randomized controlled trial. This trial included a baseline period of 1 week and a treatment period of 6 weeks with electroacupuncture (EA) or sham electroacupuncture (SA). The patients were randomly assigned to 2 groups (EA group or SA group). Participants who showed a decrease in urine leakage by at least 50% from baseline level, as measured by 1-hour pad at week 6, were defined as responders. Baseline characteristics associated with response to acupuncture therapy (e.g., demographic, comorbidities, and lifestyle-related factors) were identified by logistic regression analysis and the interactions between treatment assignment and baseline characteristics assessed.This analysis included a total of 349 postmenopausal women, of whom 137 (39.3%) were classified as responders. Response rate in the EA group was significantly higher than that in the SA group (60.9% vs 18.9%, respectively; P < .001). On multivariable logistic regression analysis, only "mean number of urine pads used before treatment" remained a significant predictor of response to therapy (EA or SA). Greater weekly mean number of urine pads used before treatment showed a correlation with non-response to therapy, as the likelihood of clinical response reduced by 5.26% with increase in the weekly mean number of urine pads used (odds ratio 0.947, 95% confidence interval 0.902-0.993; P = .020). The interaction terms were not statistically significant.Postmenopausal women with SUI who used fewer number of pads per week before treatment were more likely to respond to therapy. This study provides valuable insights for pretreatment selection of women with SUI. Specific factors related to the therapeutic effects of acupuncture were not identified and need to be explored in future studies.Trial registration: Clinical Trials.gov: NCT01784172.

Keeping an Eye on Perimenopausal and Postmenopausal Endometriosis

Introduction: We aimed to describe and review the epidemiological aspect of the disease pattern of a series of perimenopausal and postmenopausal women with a histology confirmation of endometriosis. Material and Methods: We retrospectively examined the clinical records of 184 perimenopausal and 46 postmenopausal women with endometriosis. Data were collected and analyzed from 1100 patients' charts with confirmed endometriosis and involved cases from two different geographical areas, New Haven (US) and Greece. The statistical methods included ײ and the Mann-Whitney U test. In the perimenopausal group (age 45⁻54 years), there were 184 patients (16.7%) and the postmenopausal group (55⁻80 years) had 46 (4.2%). The average age of diagnosis was (49 ± 2.3) and (61.2 ± 5.1), respectively (p < 0.01). Results: Advanced endometriosis was more aggressive in the perimenopausal group (p < 0.05); in the same group, we observed a higher left-sided predisposition of endometriosis in comparison with the right side (p < 0.01). Endometrioma was the most common gynecological condition among patients with perimenopausal endometriosis in relation to the postmenopausal group (p < 0.001). Additionally, we found uterine leiomyomata more prominent in the perimenopausal group (p < 0.05). In contrast, adenomyosis was found higher in postmenopausal patients (p < 0.05); further, 24 cases with dry eye we observed. Conclusions: Postmenopausal endometriosis is an important underestimated condition. Although the reported situation is not common, various clinicopathological characteristics were observed in both groups. Clinicians should be aware that there is a correlation between endometriosis and endometriosis-associated ovarian cancer in perimenopausal and postmenopausal age.

Evaluation of quality of life and static balance in postmenopausal osteoporosis women after Tai Chi Chuan practice: an observational randomized case control study

Post-menopausal osteoporosis women are at increased risk for skeletal fractures with higher mortality and lower quality of life. Some studies have reported fall risk reduction in the elderly after Tai chi practice. Tai chi is a weight bearing mind-body exercise that has been reported to positively influence bone mineral density and improve postural control in different pathologies. The aim of this observational randomized case control study is to evaluate the effect of Tai chi on balance and quality of life in postmenopausal women with osteoporosis. A total of 98 postmenopausal osteoporosis women, aged 70.6±8.2 years (mean and standard deviation), (mean T-score of the hip and spine were-2.9± 0.92 and -2.8±1.08), have been recruited in outpatients University Physical Medicine and Rehabilitation Hospital between June 2016 and September 2018. They have been randomized to a Tai group (56 patients, mean age 71.61±7.97 years) practiced 6-month Tai chi program, two times week, plus standard care or to a Control Group (42 patients, mean age 69.71±8.61 years) practiced usual care. Patients with oncological, neurological, cognitive, vestibular and visual diseases were excluded. Patients were evaluated at baseline (T0), prior Tai chi and after 6 month (T1) with 36-Item Short Form Health Survey (SF-36), and a stabilometric-standardized exam performed for the evaluation, respectively, of the quality of life and the static balance. The groups were homogenous at baseline. T1 evaluation showed better results in Tai chi group, in SF36 Physical functioning (p level: 0.021), Physical health pain (p level: 0.020), Physical composite score (p level: 0.003) scores, compared with control group. There were not significant differences between groups in stabilometric analysis. Tai chi group showed significant better stabilometric values at T1 compared with T0 in mean anterior-posterior (p level: 0.001) and medio-lateral (p level: 0.019) velocity, in perimeter (p level 0.001) , and in the area of the ellipse ( p level 0.006) in a within group analysis. Tai chi seemed to be effective in improving physical aspects of quality of life, in postmenopausal women with osteoporosis. Standing balance seems to increase after 6 months Tai chi program, in post-menopausal also if results were not significant. Further studies will be useful to measure effects of a Tai chi longer practice, as literature suggests, and a possible reduction of falling risk and fractures.

[Levels of sex hormones, sex hormone binding globulin, antisperm antibodies and dopamine in postmanopausal women of nomadic and settled aboriginal and local caucasoid populations of the arctic territories.]

Positive changes in the society led to an improvement in quality and lifetime; as a result the menopause in women lengthens much longer, in light of this the relevance of studying hormonal changes increases, especially among the representatives of different groups living in the Arctic territories. The study was carried out on 138 women who included nomadic and settled aboriginal and local Caucasoid postmenopausal populations, permanently residing in the Arctic territories of Russia. The greatest difference in the studied blood indicators was shown between the local Caucasoid and aboriginal population. A greater imbalance in the content of dopamine in Aborigines compared with the European population was combined with a higher levels of prolactin, sex hormone binding globulin, antisperm antibodies and with lower concentrations of lutropine, progesterone, total and free testosterone. In the settled aboriginal population compared with nomadic one there were shown the larger proportion of people with low levels of dopamine, lutropine, follitropin and high levels of prolactin, sex hormone binding globulin in the presence of increased number of feedbacks in the hypothalamic-pituitary-gonadal system, which suggested more pronounced reduction of its activity. The evident imbalance of the dopamine content in the aboriginal population was combined with the absence of connections between dopamine level and the parameters of the hypothalamic-pituitary-gonadal system. Positive correlation between the contents of dopamine and lutropin in the European population suggested the stimulating effect of dopamine on the hypothalamic-pituitary-gonadal system. Affected by imbalanced dopamine content the decreased activity of gonadotropic pituitary gland function as well as the peripheral part of the hypothalamic-pituitary-gonadal system was registered in the aboriginal Arctic population in comparison with the local European one, which was more pronounced in the settled aboriginals.

Temporal Analysis of Chronic Musculoskeletal Pain and Sleep in Postmenopausal Women

STUDY OBJECTIVES

To investigate the temporal association between chronic musculoskeletal pain (CMP) and sleep in women who are postmenopausal in a 10-day actigraphic study. This is a microlongitudinal study in which 52 participants were allocated to 4 groups women who are postmenopausal: control (CTRL, n = 10), chronic musculoskeletal pain (CMP, n = 12), insomnia (INS, n = 15) and chronic musculoskeletal pain+insomnia (CMP+INS, n = 15).

METHODS

All volunteers underwent a clinical interview and completed questionnaires, used an actigraph, and kept sleep diaries for 10 consecutive days.

RESULTS

Women in the CMP+INS group presented more sleep episodes (mean of 1.02 episodes) and longer sleep latency (8.97 minutes), as well as higher pain intensity during the day compared to the other groups. Sleep duration recorded by actigraphy directly predicted pain intensity the following morning on waking, with a 1-unit increase in pain intensity, for every 6.9 minutes more of sleep. Higher pain intensity at bedtime was a significant predictor of both increased time in bed and sleep duration, meaning that for each 1-unit increase in pain intensity at bedtime, sleep duration increased by an average of 6.7 minutes.

CONCLUSIONS

Data showed that the coexistence of insomnia and CMP results in greater pain intensity and alterations in sleep homeostasis. Collectively, the data indicate that there is a bidirectional and directly proportional relationship between sleep duration and pain intensity in women who are postmenopausal with insomnia. This result strongly suggests that both sleep and pain conditions should be targeted in the treatment of women who are postmenopausal.

Exogenous Testosterone Does Not Influence 11-Oxygenated C19 Steroid Concentrations in Healthy Postmenopausal Women

Context

11β-Hydroxyandrostenedione (11OHA4), 11β-hydroxytestosterone (11OHT), and their respective peripheral derivatives, 11-ketoandrostenedione (11KA4) and 11-ketotesosterone (11KT), have been implicated in androgen-related physiopathology. Little is known of these steroids in postmenopausal women or whether exogenous testosterone therapy influences their levels.

Objective

The impact of exogenous testosterone on serum levels of 11-oxygenated steroids was determined in healthy postmenopausal women.

Participants and Methods

Levels of 19-carbon (C19) steroids were measured by liquid chromatography–tandem mass spectrometry in serum obtained at baseline and at 12 and 26 weeks from 73 healthy postmenopausal women, aged 55 to 65 years, who participated in a randomized, double-blind, placebo-controlled clinical trial assessing the effects of transdermal testosterone on cognitive performance.

Results

Of the 11-oxygenated androgens, 11OHA4 was the most abundant (median, 6.46 nmol/L; range, 1.51 to 23.82 nmol/L), with concentrations several fold greater than its precursor androstenedione (median, 1.38 nmol/L; range, 0.52 to 2.92 nmol/L). Baseline median (range) testosterone and 11KT levels were similar [0.56 (0.23 to 1.48) nmol/L; 0.85 (0.25 to 2.86) nmol/L, respectively). 11OHT was closely correlated with 11KT (Spearman rank correlation coefficient, 0.79; P < 0.001) and 11OHA4 correlated with 11KA4 (Spearman rank correlation coefficient, 0.73; P < 0.001). Testosterone therapy resulted in an increase in serum testosterone level, whereas all 11-oxygenated androgens remained unchanged throughout the 26 weeks of treatment.

Conclusion

After menopause, the adrenal production of 11-oxygenated derivatives of androstenedione and testosterone contributes importantly to the total circulating androgen pool. Exogenous testosterone does not influence the circulating levels 11-oxygenated C19 steroids.

Sexual Function Under Adequate Estrogen Therapy in Women After Oophorectomy Versus Natural Menopause

Background: There is scarce evidence regarding endogenous postmenopausal ovarian testosterone (T) production and estrogen replacement roles in different sexual domains. This study aimed to determine whether lower endogenous T in oophorectomized women that were estradiol (E2)-treated influenced global or specific domains of sexual function. Depressive and cognitive symptoms were evaluated to exclude potential confounders. Materials and Methods: Eighty-one recently postmenopausal women treated with transdermal E2, 36 with bilateral oophorectomy (O), and 45 controls (C) were investigated through hormonal profile, Female Sexual Function Index, Mini Mental, and Beck Depression Inventory. Results: T levels, as expected, were lower in O than in C (p = 0.001); nonetheless, O presented a lower risk of sexual dysfunction (55.6% vs. 85.7%, p = 0.037), due to less pain (p = 0.005), increased lubrication (p = 0.012), and satisfaction (p = 0.042). O, however, required 50% higher E2 gel doses to control vasomotor symptoms (VMS) than did C. In O, all T measurements were positively, although weakly, correlated with desire (r = 0.374-0.381, p = 0.016-0.024). E2 levels were positively correlated with arousal in all women (r = 0.338, p = 0.038) and in O (r = 0.521, p = 0.032). Depression and cognition scores did not differ between the groups. Conclusions: Despite lower T levels, O women receiving E2 therapy had better global sexual function. Earlier onset and longer E2 treatment could have prevented vulvovaginal atrophy in O. Oophorectomized patients may require higher doses of E2 replacement. E2 levels, achieved by appropriate hormone therapy for VMS control, and very low T levels correlated with distinct sexual domains and may act in complementary areas of sexuality in postmenopausal women.

Association of Periodontal Disease and Edentulism With Hypertension Risk in Postmenopausal Women

BACKGROUND

Multiple cross-sectional epidemiologic studies have suggested an association between periodontal disease and tooth loss and hypertension, but the temporality of these associations remains unclear. The objective of our study was to evaluate the association of baseline self-reported periodontal disease and edentulism with incident hypertension.

METHODS

Study participants were 36,692 postmenopausal women in the Women's Health Initiative-Observational Study who were followed annually from initial periodontal assessment (1998-2003) through 2015 (mean follow-up 8.3 years) for newly diagnosed treated hypertension. Cox proportional hazards regression with adjustment for potential confounders was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Edentulism was significantly associated with incident hypertension in crude (HR (95% CI) = 1.38 (1.28-1.49)) and adjusted (HR (95% CI) = 1.21 (1.11-1.30)) models. This association was stronger among those <60 years compared to ≥60 years (P interaction 0.04) and among those with <120 mm Hg systolic blood pressure, compared to those with ≥120 mm Hg (P interaction 0.004). No association was found between periodontal disease and hypertension.

CONCLUSIONS

These findings suggest that edentulous postmenopausal women may represent a group with higher risk of developing future hypertension. As such improved dental hygiene among those at risk for tooth loss as well as preventive measures among the edentulous such as closer blood pressure monitoring, dietary modification, physical activity, and weight loss may be warranted to reduce disease burden of hypertension. Further studies are needed to clarify these results and further elucidate a potential role of periodontal conditions on hypertension risk.
