Preservation of Vascular Endothelial Function in Late-Onset Postmenopausal Women.
Circ Res

Department of Integrative Physiology, University of Colorado Boulder (S.D., K.O.M., K.R.L., K.H.A., D.H.C., K.A.F., D.R.S., M.J.R.).
Background: Postmenopausal women (PMW) who complete menopause at a late age (55+ years) have lower cardiovascular disease risk than PMW who complete menopause at a normal age (45-54 years). However, the influence of late-onset menopause on vascular endothelial dysfunction is unknown. Moreover, the mechanisms by which a later age at menopause may modulate endothelial function remain to be determined.

Objective: , a representative tumour suppressor gene with sex bias, is frequently altered in urothelial carcinoma (UC). The specific impacts of mutations on gender-based clinical outcomes in UC remain poorly understood.
Methods And Analysis: We enrolled 2438 patients with UC from seven independent real-world cohorts possessing comprehensive clinical and genomic data.
Immune dynamics throughout life in relation to sex hormones and perspectives gained from gender-affirming hormone therapy.

Biological sex is closely associated with the properties and extent of the immune response, with males and females showing different susceptibilities to diseases and variations in immunity. Androgens, predominantly in males, generally suppress immune responses, while estrogens, more abundant in females, tend to enhance immunity. It is also established that sex hormones at least partially explain sex biases in different diseases, particularly autoimmune diseases in females.

Background: Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide, with uterine atony accounting for approximately 70% of PPH cases. However, there is currently no effective prediction method to promote early management of PPH. In this study, we aimed to screen for potential predictive biomarkers for atonic PPH using combined omics approaches.

Sex differences in immune system aging significantly impact disease susceptibility and vaccine responses among older adults, but with notable disparities between men and women. This area has gained importance because vaccines can exhibit differential efficacy by sex in aging populations, underscoring the need for sex-specific strategies. As the global population ages, understanding these sex-based immune differences is crucial for developing targeted interventions for age-related diseases.
