Objective: To explore the association between anxiety and frailty in community-dwelling postmenopausal women. Methods: This was a cross-sectional study in which 390 postmenopausal women (aged 60–83 years) who were attending a comprehensive care program were surveyed between January 2018 and February 2020. Each participant was administered a validated Spanish version of the Hospital Anxiety and Depression Scale (HADS) to assess their anxiety status. Those scoring 8 or higher on the anxiety subscale of the HADS were indicative of anxiety. The assessment of frailty utilized the Fried's phenotype, with a diagnosis of frailty established if the participant met at least three out of the five criteria. Factors associated with frailty were analyzed using multivariate logistic regression. Results: The mean age of participants was 70.08 years, with an average of 12.58 ± 3.19 years since menopause. Frailty was diagnosed in 43.85% of the total series, while anxiety was present in 41.08%, rising to 69.59% in participants with frailty. Neither body mass index, years since menopause, educational level, economic status, nor smoking habit demonstrated significant associations with frailty. Upon multivariate analysis, anxiety (OR 8.56), multimorbidity (OR 2.18), and age (OR 2.73) emerged as independently associated with frailty (p <.001, p =.005, and p <.001, respectively). Conclusions: Among postmenopausal women with frailty, anxiety was detected in over two thirds of cases and was independently associated with frailty. This underscores the relevance of implementing anxiety screening in comprehensive care programs for postmenopausal women, with the goal of improving frailty through anxiety diagnosis and treatment.

Endothelial dysfunction and denudation are considered a first step in atherosclerosis. Endothelial proliferation is key for cellular repair. The effect of bazedoxifene on the vascular endothelium has not been explored. We investigated the effect of bazedoxifene on endothelial cell proliferation. Primary cultures from human umbilical artery endothelial cells were used in dose-response experiments (0.1, 1.0, and 10.0 EC50 dose) with bazedoxifene, estradiol, raloxifene and a combination of bazedoxifene and estradiol. Proliferation was assessed with the XTT colorimetric cell-proliferation assay. The possible participation of cyclins A, B, D1 and p27Kip1 was analyzed by the measurement of their expression at both the protein and the gene levels. A significant increase of similar size for cell proliferation was obtained with bazedoxifene, estradiol and raloxifene, but no significant change was observed for the association of bazedoxifene and estradiol. The impact was detected at the first 0.1 EC50 dose and was not dose-dependent. Estradiol achieved a significant increase in the protein expression of cyclin A and p27Kip1, but no change was detected for the other compounds at either the gene or protein level. Bazedoxifene demonstrated a proliferative effect of similar size to estradiol in cultured human umbilical artery endothelial cells. The molecular mechanisms need further investigation.
