At the American Physiology Summit 2023 session entitled, “Mental Health for Graduate Students,” numerous students expressed struggling with poor mental well-being primarily because of negative experiences during their graduate training. In fact, studies show that up to 50% of graduate students report symptoms of depression, anxiety, or burnout during their training, and poor mental well-being is a major contributor to students’ decision to leave academia. Most of the current solutions focus on treatment or wellness strategies; while these are important and necessary, the training environment or culture that often contributes to worsening well-being continues to persist. In this collaborative article between trainees and mentors across various career stages, we discuss how the pace of scientific advancements and the associated competition, lack of sufficient support for students from diverse backgrounds, and mentor-mentee relationships crucially influence graduate students’ mental well-being. We then offer specific solutions at the individual, institutional, and national levels that can serve as a starting point for improving graduate students’ mental health and overall training experience.

Premenopausal women have a lower incidence of cardiovascular disease (CVD) compared with their age-matched male counterparts; however, this discrepancy is abolished following the transition to menopause or during low estrogen states. This, combined with a large amount of basic and preclinical data indicating that estrogen is vasculoprotective, supports the concept that hormone therapy could improve cardiovascular health. However, clinical outcomes in individuals undergoing estrogen treatment have been highly variable, challenging the current paradigm regarding the role of estrogen in the fight against heart disease. Increased risk for CVD correlates with long-term oral contraceptive use, hormone replacement therapy in older, postmenopausal cisgender females, and gender affirmation treatment for transgender females. Vascular endothelial dysfunction serves as a nidus for the development of many cardiovascular diseases and is highly predictive of future CVD risk. Despite preclinical studies indicating that estrogen promotes a quiescent, functional endothelium, it still remains unclear why these observations do not translate to improved CVD outcomes. The goal of this review is to explore our current understanding of the effect of estrogen on the vasculature, with a focus on endothelial health. Following a discussion regarding the influence of estrogen on large and small artery function, critical knowledge gaps are identified. Finally, novel mechanisms and hypotheses are presented that may explain the lack of cardiovascular benefit in unique patient populations.
