Effects of stress and sex on acquisition and consolidation of human fear conditioning
We examined the relationship between stress hormone (cortisol) release and acquisition and consolidation of conditioned fear learning in healthy adults. Participants underwent acquisition of differential fear conditioning, and consolidation was assessed in a 24-h delayed extinction test. The acquisition phase was immediately followed by an 11-min psychosocial stress period (arithmetic test combined with a public speech). Salivary cortisol was sampled at various time points before and after acquisition and retention of fear conditioning. Results showed two effects of endogenous cortisol. Post-acquisition cortisol correlated with fear acquisition in male but not female participants. In addition, post-acquisition cortisol correlated with consolidation of fear but only in those participants with high cortisol levels. We conclude that in the short term, a robust and sexually dimorphic relationship exists between fear learning and stress hormone levels. For those participants whose fear learning is accompanied by high stress hormone levels, a long-term relationship exists between cortisol release and memory consolidation. These short-term and long-term effects may relate to the differential involvement of mineralocorticoid and glucocorticoid receptor subtypes, respectively. The findings have implications for understanding the role of stress, sex, and hormones in different stages of fear learning and memory
Changes in Burn Surgery Operative Volume and Metrics due to COVID-19
Due to COVID-19, hospitals underwent drastic changes to operating room policy to mitigate the spread of the disease. Given these unprecedented measures, we aimed to look at the changes in operative volume and metrics of the burn surgery service at our institution. A retrospective review was conducted for operative cases and metrics for the months of March to May for 2019, 2020, and 2021, which correspond with pre-COVID, early COVID (period without elective cases), and late COVID (period with resumed elective cases). Inclusion criteria were cases related to burns. Case types and operative metrics were compared amongst the three time periods. Compared to the hospital, the burn service had a smaller decrease in volume during early COVID (28.7% vs. 50.1%) and exceeded pre-pandemic volumes during late COVID (+21.8% vs. -4.6%). There was a significant increase in excision and grafting cases in early and late COVID periods (p \u3c .0001 and p \u3c .002). There was a significant decrease in laser scar procedures that persisted even during late COVID (p \u3c .0001). The projected and actual lengths of cases significantly increased and persisted into late COVID (p \u3c .01). COVID-19 related operating room closures led to an expected decrease in the number of operative cases. However, there was no significant decline in the number of burn specific cases. The elective cases were largely replaced with excision and grafting cases and this shift has persisted even after elective cases have resumed. This change is also reflected in increased operative times
