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.

Background Context: The prevalence of skeletal fractures shows a marked geographic variability; however, data regarding the Greek population remain limited., Purpose: To evaluate the frequency of asymptomatic vertebral fractures (VFs), and potential risk factors, in a large sample of Greek postmenopausal women., Study Design: A cross-sectional study at the University Menopause Clinic., Patient Sample: Four hundred fifty-four postmenopausal women aged 35 to 80 years, with an average menopausal age of 9.2±7.1 years., Outcome Measures: They included medical history, anthropometric and biochemical parameters, bone mineral density (BMD) at lumbar spine (LS) and femoral neck (FN), and LS lateral radiographs., Methods: Lumbar spine lateral radiographs were evaluated according to quantitative procedures, aiming to identify VFs. Anthropometric and biochemical parameters and values of BMD were compared according to the presence of VFs., Results: A total of 37 (8.15%) women had at least one VF. Lumbar spine and FN-osteoporosis was identified in up to 23.1% and 40.9% subjects with prevalent VFs, respectively. The prevalence of VFs was largely associated with age, with women aged 60 years or more presenting an up to fourfold risk compared with younger women. Moreover, the presence of VFs was associated with higher menopausal age, advanced age at menarche, a history of early menopause, and prolonged lactation. Lower LS-BMD and, especially, FN-BMD were negatively associated with VF prevalence (prevalent VF vs. no VF: LS-BMD, 0.89±0.16 g/cm(2) vs. 0.98±0.16 g/cm(2), p=.010; FN-BMD, 0.72±0.10 g/cm(2) vs. 0.81±0.12 g/cm(2), p=.008)., Conclusions: Asymptomatic VFs are common among Greek healthy middle-aged postmenopausal women. More than 50% subjects with prevalent VFs present with normal BMD or osteopenia. Age and bone density classification at the FN presented the strongest association with the prevalence of VFs., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Aim: Epithelial cadherin (E-cadherin), a transmembrane glycoprotein involved in calcium-dependent homophilic cell-cell adhesion, is expressed aberrantly during cervical carcinogenesis. E-cadherin expression and putatively implicated predictors in healthy women remain a rather under-investigated area. The objective of this study is to evaluate the possible associations between E-cadherin expression and reproductive/lifestyle factors in cervical epithelial cells from postmenopausal women., Methods: A total of 105 healthy postmenopausal women (aged 45-68 years old) attending a university menopause clinic were enrolled in this cross-sectional study. Pap smears were derived and E-cadherin immunostaining was evaluated in squamous, glandular and squamous metaplastic cells, using a semi-quantitative method (rating scale: 0-3). Reproductive and lifestyle factors were obtained from patients' chart review., Results: In squamous cells, women with a history of 0-1 deliveries presented with a higher score vs women with 2-4 deliveries (P = 0.003). Social drinkers and women drinking alcohol daily exhibited a higher E-cadherin immunostaining score in squamous cells vs non-drinkers (0.96 +/- 0.72 vs 0.56 +/- 0.65, P = 0.004). A higher dietary calcium intake was marginally correlated with a lower staining score in squamous cells (0.94 +/- 0.78 for low, 0.71 +/- 0.70 for average, 0.45 +/- 0.52 for high consumption, P = 0.073)., Conclusions: E-cadherin expression seems to be associated with reproductive history and lifestyle habits in squamous cervical cells from healthy postmenopausal women. E-cadherin might participate in the molecular mechanisms underlying the role of parity as a risk factor for cervical cancer.

Objective: To assess the association of common polymorphisms involved in lipoprotein oxidation, platelet activation, and cholesterol and homocysteine metabolism with subclinical atherosclerosis and indices of endothelial function and arterial elasticity in healthy postmenopausal women., Design: The study investigated 84 healthy postmenopausal women recruited from the Menopause Clinic of the 2nd Department of Obstetrics and Gynecology, University of Athens, Aretaieion Hospital. The following polymorphisms were genotyped: apolipoprotein B 3500, apolipoprotein E (E2/E3/E4), cholesterol 7 alpha-hydroxylase A-204C (CYP A-204C), cholesterol ester transfer protein B1/B2, glycoprotein IIIa leu33pro, integrin beta 3 PLA1/PLA2, plasminogen activator inhibitor 1 4G/5G, paraoxonase 1 gln192 arg, and methylenetetrahydrofolate reductase ala222val. Ultrasound examination aimed to assess the presence of atherosclerotic plaque and to measure intima-media thickness in the carotid and femoral arteries and to estimate the augmentation index, brachial flow-mediated dilatation, and radial and femoral pulse-wave velocity., Results: The cholesterol 7 alpha-hydroxylase A-204C polymorphism was positively associated with the presence of atherosclerotic plaque (P = 0.004) and carotid and femoral intima-media thickness (P = 0.047 and P = 0.025, respectively)., Conclusions: The CYP A-204C polymorphism was positively associated with subclinical atherosclerosis in healthy postmenopausal women. It remains to be clarified whether the presence of these polymorphisms may be valuable in assessing the inherent risk among postmenopausal women.

Objective: To investigate the effect of continuous combined hormone therapy and raloxifene on serum VE-cadherin., Design: The study was double blinded, with a placebo run-in period of 28-50 days., Setting: University menopause clinic., Patient(s): Twenty-eight healthy postmenopausal women devoid of climacteric complaints., Intervention(s): Subjects were randomized to 17beta-estradiol (2 mg) + norethisterone acetate (1 mg; E(2)-NETA) or raloxifene hCL (60 mg) for a period of 6 months., Main Outcome Measure(s): Serum VE-cadherin, which was estimated at baseline and at month 6., Result(s): Serum VE-cadherin decreased significantly in both E(2)-NETA and raloxifene groups (raloxifene baseline +/- SD: 1.17 +/- 0.44 ng/mL, 6 months: 0.82 +/- 0.29 ng/mL; E(2)-NETA baseline: 1.19 +/- 0.47 ng/mL, 6 months: 0.92 +/- 0.49 ng/mL). Percentage changes from baseline were -21.7 +/- 24.3 for E(2)-NETA and -26.0 +/- 20.6 for raloxifene., Conclusion(s): The effect of E(2)-NETA and raloxifene suggests that these drugs may preserve interendothelial junction integrity and control vascular permeability. Although this effect may influence the progress of the atheromatous lesion, its clinical impact on coronary artery disease (CAD) remains uncertain.

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. [ABSTRACT FROM AUTHOR]

Contradictory results have been reported regarding a relationship between serum lipid levels and bone mineral density. The purpose of this study was to further investigate a possible relationship between those parameters in Greek postmenopausal women. A total of 591 patients followed at a tertiary hospital were examined for seven different lipid factors in relation to dual-emission X-ray absorptiometry measurements at the lumbar spine. Lipoprotein-a was the only lipid measurement that univariately showed an almost significant trend of association with bone mass category (analysis of variance [ANOVA] p value 0.062 for Ln(Lipoprotein-a)). In multiple regression, it was noted that a non-significant negative trend of association of high density lipoprotein (HDL) cholesterol and Apolipoprotein AI with lumbar T-score ( p value 0.058 and 0.075, respectively). In age subgroup analysis, Lipoprotein-a and Ln(Lipoprotein-a) presented a negative correlation with lumbar T-score for women with age ≥ 53 years ( p value 0.043 and 0.070, respectively), while a negative correlation of HDL and Apolipoprotein AI levels with lumbar T-score remained in women with age < 53 years ( p value 0.039 and 0.052, respectively). The findings do not support a strong relationship between lipid levels and bone mass measurements. [ABSTRACT FROM AUTHOR]

Objective: To assess the effect of continuous combined hormone replacement therapy (HRT) or tibolone on serum total homocysteine (tHcy) levels in postmenopausal women. Study design: Ninety-five postmenopausal women aged 41–68 years were included in the study. Seventy-three women with climacteric complaints, osteopenia or osteoporosis received either conjugated equine estrogens 0.625 mg combined with medroxyprogesterone acetate 5 mg (CEE/MPA, n=31) or tibolone 2.5 mg (n=42). Twenty-two healthy women, matched for chronological and menopausal age, served as controls. Serum tHcy levels were assessed at baseline, 6, 12 and 18 months. Results: No difference was recorded between groups regarding demographic characteristics or mean baseline serum tHcy. Serum tHcy levels decreased significantly in the CEE/MPA compared to baseline (change at 18 months: −3.9%, P<0.05). The magnitude of the decrease was higher in the subgroup of women with baseline tHcy levels above the median (change at 18 months: −15.0%, P<0.01). No change in tHcy levels was detected in the tibolone group throughout the study period, either in the whole group (change at 18 months: 1.9%, NS) or in the subgroup with baseline tHcy levels above the median (change at 18 months: −3.23%, NS). Conclusion: Continuous CEE/MPA reduces tHcy especially in women with high pretreatment tHcy levels. Tibolone has no effect on serum tHcy levels at least during the first 18 months of therapy. Larger studies with longer follow-up are required to confirm these results. [Copyright &y& Elsevier]
