A quasi-experimental comparative mixed-method design was utilized for the study with a convenience sample of 132 students. Data analysis indicates a statistically significant difference between overall scores for satisfaction, self-confidence, and engagement for defined observer roles (n = 67) versus traditional observer roles (n = 65). Students' perceptions of satisfaction, self-confidence, and engagement were increased with the use of defined observer roles.Depression, with or without concomitant anxiety, is one of the most burdensome medical conditions worldwide. Depression affects women more often than men and may cause significant impairment. Reproductive phase-related windows of vulnerability for depression (new or recurrent) have been recognized, including the menopause transition. Midlife depression is likely influenced by both menopause- and nonmenopause-related factors. Antidepressants and cognitive behavioral therapy remain first-line treatment options for moderate to severe major depressive disorder at any time, with proven efficacy and tolerability in midlife women. Transdermal estradiol can also be part of the treatment armamentarium, but its use as a prophylaxis against midlife depressive symptoms, although promising, warrants further investigation.OBJECTIVES Neurologic damage following cardiac arrest remains a major burden for modern resuscitation medicine. Cardiopulmonary resuscitation with extracorporeal circulatory support holds the potential to reduce morbidity and mortality. Furthermore, the endogenous gasotransmitter carbon monoxide attracts attention in reducing cerebral injury. We hypothesize that extracorporeal resuscitation with additional carbon monoxide application r
