RESUMEN

BACKGROUND: Female sexual dysfunction (FSD) has been suggested to be correlated with the burden of cardiovascular risk factors. AIM: We aimed to evaluate the possible association between functional indices of vascular function and FSD scores in apparently healthy postmenopausal women. METHODS: This cross-sectional study included 116 postmenopausal women who underwent assessment of endothelial function with measurement of flow-mediated dilation (FMD) of the branchial artery and arterial stiffness estimation with measurement of the carotid-femoral pulse wave velocity (PWV). We used the Greene Climacteric Scale to evaluate vasomotor symptomatology, the Female Sexual Function Index (FSFI) to evaluate FSD and the Beck Depression Inventory to evaluate mood disorder. Low sexual function was defined as an FSFI score <26.55. OUTCOMES: These included FSFI and low sexual function scores as well as measures of PWV and FMD. RESULTS: Sexual function scores were associated with measures of blood pressure (normal vs low sexual function; systolic blood pressure: 120.2 ± 15.0 mm Hg vs 113.4 ± 14.6 mm Hg; analysis of covariance P = .026; diastolic blood pressure: 75.9 ± 10.5 mm Hg vs 70.3 ± 9.9 mm Hg; analysis of covariance P = .012; both adjusted for age, body mass index, current smoking, and PWV). Systolic blood pressure, but not diastolic blood pressure, was associated with FSFI (B = 0.249, P = .041) and PWV (B = 0.392, P < .001). PWV measures were associated with FSFI (B = -0.291, P = .047) and pulse pressure (B = 0.355, P = .017). FMD measures were also associated with FSFI (B = 0.427, P = .033). All models were adjusted for age, body mass index, current smoking, insulin resistance, vasomotor symptomatology, and Beck Depression Inventory. CLINICAL IMPLICATIONS: Our findings demonstrate that lower scores of sexual function are associated with deteriorated vascular function mainly manifested as arterial stiffening, further contributing to systolic blood pressure changes. STRENGTHS AND LIMITATIONS: The strength of this study is the carefully selected healthy sample of postmenopausal women, with simultaneous assessment of climacteric symptomatology and mood disorders. The limitations include the small sample size, the cross-sectional design, and the recruitment of consecutive outpatients of a university menopause clinic. CONCLUSION: Longitudinal studies and interventions to improve FSD should further assess the clinical relevance of these findings.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The genitourinary syndrome of menopause (GSM), apart from symptoms related to vulvovaginal atrophy (VVA), also consists of lower urinary tract symptoms (LUTS). Based on the common embryological origin of the genital and lower urinary system, the presence of estrogen receptors, and the high prevalence of VVA and LUTS in the menopausal population, the two conditions can coexist. This study is aimed at investigating the prevalence and risk factors of LUTS in a sample of Greek peri- and postmenopausal women. METHODS: Four hundred and fifty (450) women, aged 40-70 years, attending three outpatient gynecology clinics for routine examination, completed a structured interview and responded to a validated questionnaire (International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms, ICIQ-FLUTS). RESULTS: Urinary urgency or frequency affected 51.6% and dysuria 43.6% of the participants. Mild urgency or frequency was described by 25.6%, moderate by 14.4%, and severe by 11.6% of the women. Mild dysuria was reported by 26.26%, moderate by 5.8%, and severe by 11.6%. Age, weight, BMI, and number of pregnancies and abortions correlated with a higher ICIQ-FLUTS score. Women with moderate/severe symptoms of VVA, such as irritation, a burning sensation, and pruritus of the vulva or vagina, had a higher ICIQ-FLUTS score than women without such symptoms (beta coefficient 2.42, CI 1.204, 3.635, p < 0.001). CONCLUSIONS: Lower urinary tract symptoms are very common among peri- and postmenopausal women and are linked to symptoms of VVA. Our data support the need for prompt evaluation of women transitioning to menopause, as these symptoms compromise the quality of life.

RESUMEN

OBJECTIVE: This study aimed to assess the possible association of adherence to the Mediterranean diet (MD) with muscle strength and body composition. METHODS: The cross-sectional study evaluated 112 postmenopausal women (aged 41-71 years). Fasting blood samples were obtained for biochemical/hormonal assessment. The Mediterranean Dietary Score (MedDietScore) was calculated and used to stratify adherence by tertiles (low [T1], moderate [T2] or high [T3]). Handgrip strength (HGS) was measured by dynamometry and body composition with dual-X-ray absorptiometry. RESULTS: Women with low-moderate MedDietScore (T1/T2) had lower HGS values than those with higher scores (19.5 ± 4.9 kg vs. 21.9 ± 3.9 kg, p = 0.023). A linear stepwise increase of HGS values per MedDietScore tertile was found (T1 vs. T2 vs. T3: 18.4 ± 4.4 kg vs. 20.6 ± 5.2 kg vs. 21.9 ± 3.9 kg, ANOVA p-value for linear trend = 0.009, ANCOVA p-value = 0.026). Multivariable models confirmed that HGS values were independently associated with the MedDietScore (ß-coefficient = 0.266, p = 0.010). Lean mass values were associated with the MedDietScore (ß-coefficient = 0.205, p = 0.040). All models were adjusted for age and cardiometabolic risk factors. CONCLUSIONS: The data suggest that the higher the adherence to the MD, the better the muscle strength and lean mass in postmenopausal women. Prospective studies are required to evaluate the significance of these observations in cardiovascular prevention strategies at midlife.

RESUMEN

OBJECTIVE: To evaluate the possible association between thyroid function within the euthyroid range and musculoskeletal parameters as well as body composition in a sample of postmenopausal women. METHODS: This cross-sectional study included 96 postmenopausal women with serum thyroid-stimulating hormone (TSH) within the normal laboratory reference range. Fasting venous blood samples were obtained for biochemical/hormonal assessment. Bone status and body composition were measured using Dual Energy X-ray absorptiometry (DXA). Physical activity was quantified using the International Physical Activity Questionnaire (IPAQ) index. RESULTS: Serum TSH correlated with handgrip strength (HGS, r-coefficient = 0.233, p = .025), and total body bone mineral density (BMD) T-score values (r-coefficient = 0.321, p = .003). HGS measures were associated with BMD (r-coefficient = 0.415, p < .001), with bone mineral content (BMC, r-coefficient = 0.427, p < .001), and lean mass (r-coefficient = 0.326, p = .003). Women with low muscle strength, defined as HGS < 16 kg, had lower TSH levels than women with normal muscle strength (low vs. normal muscle strength, ANCOVA 1.13 ± 0.49 mU/L vs. 1.60 ± 0.83 mU/L, p = 0.024) independently of age, BMD, percentage of body fat or absolute lean mass. Multivariable linear regression analysis showed that HGS values were associated with TSH measurements (ß-coefficient = 0.246, p = .014) and BMD T-score values (ß-coefficient = 0.306, p = .002). All models were adjusted for age, body mass index (BMI), vitamin D, low-density lipoprotein cholesterol, current smoking, physical activity, and homeostasis model assessment of insulin resistance. CONCLUSIONS: In this sample of postmenopausal women, lower serum TSH values, within normal range, were associated with lower muscle strength compared to higher normal TSH values. Further research is needed to elucidate the significance of our preliminary findings.

RESUMEN

BACKGROUND: Postmenopausal sexual function presupposes the integration of hormonal, neural, and vascular interactions and is subject to optimal crosstalk among psychological, interpersonal, cultural, and environmental factors. Sense of coherence (SOC) reflects a person's ability to cope with stressors and may influence the occurrence of menopausal symptoms and sexual dysfunction. AIM: To investigate the association of severity of climacteric symptoms, cardiometabolic risk factors, and SOC with sexual function in postmenopausal women. METHODS: Overall 281 sexually active postmenopausal women without significant psychopathology or cardiovascular disease attending the Menopause Unit of Aretaieion Hospital were evaluated by the Female Sexual Function Index (FSFI), Greene Climacteric Scale, Beck Depression Scale, and Sense of Coherence Scale. Hormonal and biochemical parameters and cardiometabolic risk factors were evaluated. FSFI scores <26.5 were considered pathologic. OUTCOMES: Total and subdomain scores of sexual response were determined. RESULTS: Pathologic FSFI scores were found in 79.7% of the sample. Linear models of multivariable regression analysis showed that FSFI scores were associated with (1) Beck scores (b = -0.200; 95% CI, -0.472 to -0.073, P = .001), vasomotor symptom severity (b = -0.324; 95% CI, -0.985 to 0.051; P < .001), and age and (2) SOC (b = 0.150, 95% CI, 0.036-0.331; P = .008), vasomotor symptom severity (b = -0.361; 95% CI, -0.743 to 0.245; P < .001), and age. Both models were adjusted for menopausal age, diabetes mellitus, hypertension, type of menopause, and menopausal hormone therapy intake. SOC was associated with Beck depression scores (ß = -0.487, P < .001; Greene Climacteric Scale total scores, ß = -0.199, P < .001). FSFI score <26.5 vs >26.5 was associated with SOC (odds ratio, 0.982; 95% CI, 0.563 to 1.947; P = .006) and moderate to severe vasomotor symptom severity (odds ratio, 2.476; 95% CI, 1.478 to 3.120; P = .009) independent of age, diabetes mellitus, hypertension, menopausal hormone therapy intake, type of menopause, or Beck depression classification. CLINICAL IMPLICATIONS: The results indicate the importance of psychometric assessment of postmenopausal women when presenting with scores of low sexual function. The severity of vasomotor symptoms should also be addressed in any case. STRENGTHS AND LIMITATIONS: This is the first study investigating the relationship between SOC and sexuality in menopause in a carefully selected homogenous population. Limitations included the cross-sectional design and the fact that sexual distress was not assessed. CONCLUSIONS: Pathologic FSFI scores were highly prevalent in this sample of postmenopausal women. FSFI is associated positively with age and severity of vasomotor symptoms and negatively with SOC.

RESUMEN

To evaluate the effectiveness of a structured education program on lifestyle habits, which is also incorporating teaching on deep breathing, progressive muscle relaxation, and guided visualization, in the control of various components of the climacteric symptomatology in peri- and postmenopausal women. Sixty-one women aged 40-65 years with varying climacteric and stress symptoms were included in this study. Women were randomly assigned to the intervention group (31) or the control group (30). The intervention group followed an 8-week stress management program. The following parameters were assessed at baseline and at the end of the 8-week follow-up period in both groups: climacteric symptoms (Green Climacteric Scale (GCS)), sleep quality (Pittsburg Sleep Quality Index (PSQI)), mood status (Depression-Anxiety-Stress Scale), self-esteem (Rosenberg Self-esteem Scale), and health-related control (health locus of control (HLC)). A mixed-model ANOVA showed significant time × group × GCS interaction (within subjects: F = 23.830, p value<0.001; between subjects: F = 39.078, p value<0.001). With regard to HLC, there was a non-significant between subjects but a significant within-subjects effect (HLC × group × time, F = 3.848, p value = 0.024). Regarding DASS scores, there was a significant between-subjects' effect (F = 10.258, p value = 0.003) but a non-significant within-subjects' effect. With regard to PSQI, the analysis showed significant within-subjects' effects (PSQI × group × time: F = 4.691, p value = 0.003) and non-significant between-subjects' effects (F = 0.022, p = 0.883). Finally, regarding RSS, there was a significant within-subjects' (RSS × group × time, F = 4.183, p value = 0.029) but non-significant between-subjects' effect (F = 1.582, p value = 0.213). Stress management may offer an alternative approach to the management of climacteric symptoms.

RESUMEN

The development of atypical vs typical anorexia nervosa (AN) might be explained by the genetic background. We assessed the link between the subtypes of AN and the genetic polymorphisms of the thrombotic panel and the methyltetrahydrofolate reductase (MTHFR) gene. This cross-sectional pilot study recruited 48 girls with AN and 10 age-matched control girls with normal menstruation. We recorded anthropometric parameters and obtained blood samples for genotyping and hormonal assessment. Classification of AN was performed according to the DSM-V criteria. Girls with AN had 2.66 times higher odds of carrying at least one genetic polymorphism from the MTHFR panel (C677T and A1298C) compared with girls without AN (OR = 2.660, p-value = 0.041; CI 95% 1.057-6.720). The presence of atypical vs typical AN was associated independently with the presence of any of the assessed MTHFR polymorphisms (C677T, OR = 4.929, 95% CI 1.076-22.579, p-value = 0.040; A1298C, OR = 0.097, 95% CI 0.011-0.866, p-value = 0.037) in age and estrogen adjusted models. The atypical presentation of AN is mainly linked with higher prevalence of the MTHFR C677T and lower prevalence of the A1298C polymorphism.

RESUMEN

Objective: To evaluate the association between a personal history of lactation and indices of subclinical atherosclerosis in postmenopausal women.Methods: We evaluated the association between a history of breastfeeding and indices of subclinical atherosclerosis (pulse wave velocity, PWV; intima-media thickness [IMT]; atherosclerotic plaque presence) in 197 parous postmenopausal women with history of breastfeeding.Results: Women who reported breastfeeding ≥6 months when compared with women who reported breastfeeding for 1-5 months exhibited significantly lower values of common carotid artery IMT (Model R2=15.7%, b-coefficient = -0.170, 95% CI: -0.208-0.001, p-value = .019) and lower odds of subclinical atherosclerosis (Model X2=28.127, OR = 0.491, 95% CI 0.318-0.999, p-value = .049), adjusting for traditional cardiovascular risk factors.Conclusions: Postmenopausal women with a history of breastfeeding for at least 6 months have a lower prevalence of subclinical atherosclerosis, independently of traditional cardiovascular risk factors. A longer duration of breastfeeding may have a beneficial effect on subclinical atherosclerosis later in life.

RESUMEN

Introduction: We aimed to investigate the incidence of hypertension and to identify potential risk factors in healthy, non-diabetic recently postmenopausal Greek women with normal renal function.Patients and methods: This retrospective cohort study evaluated 141 recently postmenopausal women at baseline and annually thereafter (follow-up time: 1 to 8 years). Blood samples were obtained, and ultrasound evaluations were performed at baseline. A detailed medical history, anthropometric parameters, blood pressure and cardiovascular risk factors were recorded for every woman at each visit. Incident hypertension was defined as the first occurrence of office systolic or diastolic blood pressure, measured at 2 different visits within 2 months or history of initiation of antihypertensive medication.Results: Incident hypertension was diagnosed in 30 out of 141 women (21.3%). The median time to incident hypertension was 3.5 years. Adiposity, elevated cholesterol and triglyceride levels, insulin resistance and parity were positively associated with incident hypertension. In multivariate analysis, however, obesity and insulin resistance were the only statistically significant variables associated with more than 3-fold and 2-fold respectively increased risk of incident hypertension (HOMA-IR, O.R = 1.988, p-value =.043; obesity, O.R = 3.746, p-value =.019).Conclusion: A significant proportion of women entering the menopause present incident hypertension and this is mostly associated with obesity and insulin resistance.

RESUMEN

Menopause is the condition in which the gradual decline in ovarian function finally leads to the permanent cessation of menstruation. Oestrogen deficiency may cause early symptoms during the menopausal transition and late symptoms after menopause. Menopause is a normal period of life. During this period, women need adaptation to new biological, social, and psychological parameters. Vasomotor symptoms are among the most common menopausal symptoms. Menopause per se is not correlated with specific psychiatric disorders, but data suggest that perimenopausal women are more likely to develop depressive disorders even without a previous history. Vasomotor symptoms are correlated with mood and sleep disturbances, neuroticism, anxiety, decreased cognitive function, and stress. Personality traits, social, and other factors are also important mediators of vasomotor symptoms during the menopausal transition phase. This is a review based on the existing evidence concerning the correlation between psychosomatic and vasomotor symptoms of menopause during the menopausal transition period. Healthcare providers should take these correlations into consideration when planning the treatment of vasomotor symptoms. Vasomotor symptoms during menopause are associated with significant social costs. There are numerous traditional hormone therapy, and complementary and alternative therapy including over-the-counter treatments and dietary supplements for managing menopause-related vasomotor symptoms. Additional costs include follow-up physician visits, laboratory testing, management of adverse events, and loss of productivity at work. Social support and planning may help women to deal with menopausal symptoms and may reduce overall social costs during this transitional phase.

RESUMEN

AIM OF THE STUDY: To investigate the association of personality traits with the severity of vasomotor symptoms (VMS) in a predominantly Greek population. MATERIAL AND METHODS: A questionnaire-based study of women from the Menopause Clinic of a University Hospital in Athens, Greece. Sociodemographic parameters were documented through a structured interview. All women completed the Menopause Rating Scale (MRS) for the assessment of severity of menopausal symptoms, the Hot Flush Beliefs Scale (HFBS) for the assessment of how women were coping with their symptoms and the Big Five Inventory questionnaires for the assessment of personality traits. Associations between baseline parameters and menopausal symptoms were assessed with univariate and multivariate regression analyses. RESULTS: One hundred women were included. Employed women had lower MRS sub-scores (psychological p< 0.001, somatic p< 0.047, urogenital p< 0.008). Married women scored higher in the psychological and somatic domains. Women of university educational level coped significantly better with hot flushes (ß coefficient [SE]: 0.72 [0.25], p< 0.01) and night sweats (0.57 [0.19], p< 0.01) than women of primary education, although the significance of these findings was not replicated when taking into account confounders. Regarding personality traits, women with low openness (-0.33 [0.11], p< 0.01) and empathy (-0.83 [0.37], p = 0.03) and high agreeableness (1.13 [0.21], p< 0.001) had more severe menopausal symptoms. In contrast, women with high agreeableness could better cope with their menopausal symptoms (-0.75 [0.36], p = 0.04). These associations were independent of sociodemographic factors. CONCLUSIONS: Personality traits, especially agreeableness, openness and empathy are associated with menopausal symptoms and functionality in postmenopausal women. These associations might serve as indicators of women at risk of experiencing more severe VMS.

RESUMEN

The changing hormonal milieu during the menopausal transition may contribute to the development of memory disorders. We aimed to assess the association of sex hormones with memory function in a sample of Greek middle-aged women. This pilot study included 44 women with subjective memory complaints. Memory performance was evaluated using the Hopkins Verbal Learning Test (HVLT), the Brief Visuospatial Memory test (BVMT), and the verbal digits backwards test (VSPAN), to assess verbal, visuospatial, and working memory performance, respectively. Menopausal symptoms were assessed using the Green Climacteric Scale. VSPAN backwards scores were positively associated with log-transformed free androgen index (logFAI), in models adjusted for age, education, log-transformed free estrogen index (logFEI), hypertension, and the intensity of menopausal symptoms. BVMT total scores were predicted by logFAI (b-coefficient = 0.424, p value = 0.002), education, and combined climacteric symptomatology, in a model adjusted for age, logFEI, and hypertension. Women with circulating estradiol above the median value of 10 pg/mL had better total HTLV total scores compared to women with estradiol values below the median (HTLV total scores, estradiol ≤ 10 pg/mL vs. > 10 pg/mL: 24.2 ± 3.6 vs. 30.0 ± 7.9, p value = 0.007 unadjusted). This association was affected by education and remained independent of menopausal symptoms and testosterone levels, education, and hypertension (model R 2 = 22.3%; b-coefficient = 0.318, p value = 0.024). Endogenous total estradiol is associated with verbal episodic memory, while logFAI is associated with working memory performance and visuospatial episodic memory in this sample of postmenopausal women. These associations were not influenced by age, education, or menopausal symptoms. Larger studies are necessary to evaluate the significance of our findings.

RESUMEN

Genetic variations of genes encoding the endothelial nitric oxide synthase (eNOS) and the NADH/NADPH oxidase system are related with atherosclerosis in the general population, but their significance in women is not sufficiently assessed. We investigated the potential association between the G894T polymorphism of the NOS3 gene and the C242T polymorphism of the CYBA gene with subclinical vascular disease. Seventy (70) healthy, normally ovulating, premenopausal women were recruited for this study. Venous blood samples were obtained for biochemical/hormonal assessment as well as for genotyping, using real-time PCR. Sonographically assessed indices of vascular structure and function included carotid and femoral intima-media thickness (IMT), flow-mediated dilation (FMD), carotid-femoral pulse-wave velocity (PWV), and augmentation index. The prevalence of wild type, heterozygote, and homozygote genotype was 44.3% (31/70), 54.3% (38/70), and 1.4% (1/70) for the G894T polymorphism and 38.6% (27/70), 31.4% (22/70), and 30.0% (21/70) for the C242T polymorphism, respectively. After multivariable adjustment, the hC242T polymorphism was a predictor of both internal carotid IMT (b-coefficient - 0.119, p = 0.011) and combined-IMT (b-coefficient - 0.061, p = 0.015). Systolic blood pressure, lipids, and hC242T determined values of FMD (b-coefficient - 1.604, p = 0.034). Concerning the NOS3 G894T polymorphism, carriers of the polymorphic variant had higher values of IMT and PWV compared to the wild-type subgroup (carotid bulb-IMT and PWV, heterozygotes/homozygotes vs wild type 0.7 ± 0.2 vs 0.6 ± 0.1 mm; 7.1 ± 0.8 vs 6.6 ± 0.7 m/s; p = 0.048 and p = 0.029, respectively). These differences, however, were rendered non-significant in the multivariable analysis. In healthy premenopausal women, the CYBA C242T polymorphism is an independent determinant of endothelial function and subclinical atherosclerosis of the carotid arteries. The NOS3 G894T polymorphic variant also correlated with atherosclerosis, an association probably mediated by the traditional risk factors for CVD. The relevance of these findings in the clinical setting remains to be elucidated.

RESUMEN

INTRODUCTION: The present study aimed to assess the association between ovarian volume and demographic and anthropometric parameters, as well as sex hormones and bone mineral density (BMD) in postmenopausal women. METHODS: 161 healthy postmenopausal women participated in this cross-sectional study. Fasting venous blood samples were obtained for biochemical/hormonal assessment. Anthropometric parameters included body mass index (BMI) and waist-to-hip ratio (WHR). Ultrasonography was used to estimate the average ovarian volume for each participant. BMD was measured in the femoral neck (FN) and the lumbar spine (LS) using DXA. RESULTS: Mean ovarian volume increased linearly with increasing quartiles of BMI (Q1:0.985±0.25, Q2: 1.11±0.29, Q3: 1.07±0.28, Q4: 1.19±0.38, p-value for linear trend 0.013). Ovarian volume correlated positively with BMI (r=0.128, p-value=0.038), FN BMD (r=0.233, p-value=0.003), FN T-score (r=0.223, p-value=0.004) and FN Z-score (r=0.171, p-value=0.027). Multivariate analysis showed that ovarian volume was predicted by WHR (b-coefficient=0.157, p-value=0.047) and SHBG (b-coefficient= -0.160, p-value=0.042), independently of age and BMI. Finally, FN BMD was predicted by ovarian volume, independently of age, menopausal age and BMI. CONCLUSION: Ovarian volume was positively and independently associated with adiposity indexes and femoral BMD in postmenopausal women. Lower SHBG levels were associated with higher ovarian volume. Insulin resistance may mediate these results. The significance of these findings should be assessed in larger prospective studies.

RESUMEN

The menopause transition is associated with adverse changes in cardiometabolic risk factors. We aimed to examine the association of the metabolic syndrome (MS) and its features with indices of vascular structure and function in a population of asymptomatic postmenopausal women. A total of 473 informed-consenting, nondiabetic postmenopausal women were included in the study. The MS was defined according to the Joint Definition. We evaluated the association between the presence of MS and indices of vascular structure (carotid artery intima-media thickness (IMT); atherosclerotic plaques) and function (flow-mediated dilatation (FMD); pulse wave velocity (PWV)). The mean age of women was 56.4 ± 6.7 and the mean menopausal age was 7.91 ± 6.31. The MS was present in 17.3% of our population. Mean values of PWV increased linearly with the accumulation of features of the MS. IMT was higher in women with the MS compared to women without the MS (0.78 ± 0.12 mm vs. 0.74 ± 0.11, p = .003). Multivariate analysis showed that the presence of the MS was independently associated with common carotid artery IMT (b = 0.149, p = .001), PWV (b = 0.114, p = .012) as well as central systolic and diastolic blood pressure (b = 0.293, p < .001 and b = 0.163, p < .001 respectively). The presence of the MS is associated with subclinical atherosclerosis already in the first postmenopausal decade of this sample of asymptomatic, nondiabetic women. Additional evidence is required to support the causative effect of these associations.

RESUMEN

BACKGROUND: The present study aims to examine the association of the metabolic syndrome (MS) as well as of the triglyceride-glucose index (TyG-Index), a novel marker of insulin resistance, with subclinical atherosclerosis in a cohort of postmenopausal women, stratified according to their body mass index. METHODS: A total of 473 informed-consenting, non-diabetic postmenopausal women, without overt cardiovascular disease, were included in this study. We aimed to compare the association between structural and functional indices of subclinical atherosclerosis (i.e. carotid artery intima-media thickness (IMT), flow-mediated dilation of the brachial artery, pulse wave velocity (PWV)) with the TyG-index or MS, separately for lean and overweight/obese women. RESULTS: The TyG-Index correlated significantly with carotid IMT (r=0.155, p=0.012) and PWV (r=0.157, p=0.013) only in the group of lean women. Multivariate analysis showed that subclinical atherosclerosis was predicted by MS, in the overweight/obese group (OR=2.517, 95% CI: 1.078-5.878, p=0.033), and by the TyG-Index the lean group (OR=3.119, 95% CI: 1.187-8.194, p<0.001). Using a TyG-Index cut-off value of 8.0 in the lean subpopulation, women above the cut-off had 44.1% prevalence of subclinical atherosclerosis compared to 29.4% in women below the cut-off (p=0.043). CONCLUSIONS: The TyG-Index is associated with carotid atherosclerosis and arterial stiffness mainly in lean postmenopausal women, while the MS serves as a better predictor of subclinical atherosclerosis in overweight/obese women. The TyG-Index may prove a useful marker for identifying high-risk women in the normal-weight postmenopausal population.

RESUMEN

Overt or subclinical thyroid dysfunction may affect the risk of fragility fractures. The aim of the present study was to assess the association of thyroid function and autoimmunity with vertebral fractures (VF) in a large sample of Greek postmenopausal women. This cross-sectional study recruited 335 euthyroid postmenopausal women, aged 35-79 years. Euthyroidism was verified by serum thyroid-stimulating hormone (TSH) within the laboratory reference range (0.4-4.5 µIU/mL). VFs were diagnosed by lumbar spine lateral radiographs, according to quantitative procedures. Serum free triiodothyronine (FT3), free thyroxine (FT4), TSH, as well as levels of anti-thyroglobulin (anti-TG) and thyroid peroxidase antibodies (anti-TPO) were compared according to the presence of VFs. Multivariate logistic regression showed that the presence of VFs was predicted independently by ln-TSH levels (OR = 0.290, p = 0.037) and positive anti-TG antibodies (OR = 3.308, p = 0.026) in models adjusted for age, menopausal age, and ln-HOMA-IR. Stepwise logistic regression analysis showed that the presence of VFs was predicted by menopausal age (OR = 1.120, p = 0.001), ln-TSH (OR = 0.312, p = 0.052), and thyroid autoimmunity (anti-TG and anti-TPO positive: OR = 6.637, p = 0.007) in a model that also included age and ln-HOMA-IR. Women with lower circulating TSH had higher risk of having a VF, independently of age, menopausal age, and insulin resistance. The presence of positive anti-TG/anti-TPO antibodies also indicated an elevated risk of fracture. Levels of thyroid hormones had no apparent effect on the risk of fracture. Further studies are necessary to establish the significance of our findings.

RESUMEN

AIMS: Urinary incontinence in general is a major cause of quality of life impairment, morbidity and hospitalization. Its onset is strongly linked to the menopause. Our study aimed to elucidate the possible relationship between endogenous circulating estrogens and the onset and development of stress urinary incontinence (SUI). METHODS: One hundred and thirty eight peri- and postmenopausal women with SUI were matched 1:1 with continent women based on age and BMI. Morning fasting blood samples were drawn from all subjects for assessment of estradiol (E2), FSH, LH, Testosterone, Δ4-Androstendione (Δ4Α), DHEAS, prolactin, SBHG as well as a biochemical profile (glucose, insulin, triglycerides, cholesterol, HDL, LDL, ApoA1, ApoB). Hormone and biochemical parameters were compared between continent and incontinent women. RESULTS: Incontinent women had significantly lower serum estradiol levels compared to those in the control group (17.30 ± 8.16 vs. 24.22 ± 8.99, P < 0.001). Furthermore, the same association was observed for serum Δ4Α (146.07 ± 52.63 vs. 159.99 ± 42.62, P = 0.017). These associations remained significant after controlling for age, menopausal age, BMI, and number of deliveries. CONCLUSIONS: These results may indicate that within the postmenopausal range, endogenous sex hormones may be associated with the presence of SUI in women not on menopausal hormone therapy. Neurourol.

RESUMEN

AIM: Menopause transition is associated with chronic conditions such as osteoporosis and cardiovascular disease. Concerns about the long-term safety of menopausal hormone therapy make alternative natural methods an appealing approach to management. The aim of this study was to examine the effect of royal jelly (RJ) on cardiovascular and bone turnover markers in clinically healthy postmenopausal women. METHODS: A total of 36 postmenopausal healthy women were studied in a prospective follow-up study. Participants received 150 mg of RJ daily for three months. Circulating cardiovascular risk markers [lipid profile, antithrombin-III (ATIII), Protein C, Protein S, Plasminogen Activator Inhibitor-1 (PAI-1)] and bone turnover parameters [Total calcium, phosphate (P), parathormone (PTH), total type-1 Procollagen N-terminal (P1NP), Osteocalcin and serum collagen type 1 cross-linked C-telopeptide (CTX)] were compared between the baseline and the three-month visit. RESULTS: The RJ used in this study was particularly rich in medium chain fatty acids, compounds with hypolipidemic properties, which comprised 63% of the dry weight fatty content. RJ treatment resulted in a significant increase in high density lipoprotein - cholesterol (HDL-C 60.2 mg/dL ± 12.3 versus 64.7 mg/dL ± 13.9, 7.7% increase, p = 0.0003), as well as in a significant decrease in low density lipoprotein - cholesterol (LDL-C, 143.9 ± 37.5 versus 136.2 ± 32, 4.1% decrease, p = 0.011) and in total cholesterol (224.4 ± 38.6 to 216.1 ± 36.5, 3.09% decrease, p = 0.018). No statistical significant changes were found in the remaining cardiovascular or the bone turnover parameters. CONCLUSIONS: The intake of RJ 150 mg for three months is associated with significant improvements of the lipid profile of postmenopausal women. RJ supplementation may offer an alternative method of controlling the menopause - associated dyslipidemia.

RESUMEN

PURPOSE/AIM OF THE STUDY: We evaluated possible associations between the severity of multiple sclerosis (MS) and levels of sex hormones as well as biochemical parameters in a sample of ambulatory patients. MATERIAL AND METHODS: This cross-sectional study recruited 133 adults (52 men, 66 premenopausal and 15 postmenopausal women), with relapsing-remitting MS. Fasting venous blood samples were drawn for biochemical and hormonal evaluation. These parameters were tested for possible associations with MS severity, assessed using the Expanded Disability Status Scale (EDSS)-scores. RESULTS: Follicle-stimulating hormone correlated with mean EDSS scores (r = -0.369, p = 0.038) in the premenopausal subgroup. However, this association became non-significant in the age-adjusted multivariate analysis (p = 0.141; power = 67%, type α error 0.10). Free androgen exhibited a borderline negative effect on EDSS-scores in the subgroup of men (r = -0.367, p = 0.093), which was lost after adjusting for age and duration of disease (p = 0.192; statistical power = 93%, type α error 0.05). Levels of estradiol tended to affect disability status of postmenopausal women (normal-mild vs. severe impairment: 23.33 ± 11.73pg/mL vs. 14.74 ± 6.30pg/mL, p = 0.095). Levels of sex hormones or indices of glycemic metabolism did not differ between patients presenting with EDSS scores higher or lower than the median value. CONCLUSION: Sex hormones and indices of glucose metabolism exhibited only a middle effect on EDSS scoring, which was not independent from the presence of confounders like age and duration of MS. The present study highlights the need for additional research, in order to elucidate the role of sex hormones and insulin resistance in the course of MS.
