Activation of androgen receptor-expressing neurons in the posterior medial amygdala is associated with stress resistance in dominant male hamsters.

Social stress is a negative emotional experience that can increase fear and anxiety. Dominance status can alter the way individuals react to and cope with stressful events. The underlying neurobiology of how social dominance produces stress resistance remains elusive, although experience-dependent changes in androgen receptor (AR) expression is thought to play an essential role.

Retrospective review of rates of sexually transmitted and blood-borne infection (STBBI) testing in provincial corrections facilities in Newfoundland and Labrador.

Background: Sexually transmitted and blood borne infection (STBBI) testing is recommended for people who are incarcerated (PWAI). We sought to determine the rate of STBBI testing during admissions to provincial correctional institutions in Newfoundland and Labrador (NL).

Methods: This retrospective cohort study collected the identification of all admissions records in provincial correctional facilities in NL between July 1, 2020 and June 31, 2021 using the database.

Measuring and Comparing Clinical Productivity of Individual Anesthesiologists.

Measuring and comparing clinical productivity of individual anesthesiologists is confounded by anesthesiologist-independent factors, including facility-specific factors (case duration, anesthetizing site utilization, type of surgical procedure, and non-operating room locations), staffing ratio, number of calls, and percentage of clinical time providing anesthesia. Further, because anesthesia care is billed with different units than relative value units, comparing work with other types of clinical care is difficult. Finally, anesthesia staffing needs are not based on productivity measurements but primarily the number and hours of operation of anesthetizing sites.

Dominance status modulates activity in medial amygdala cells with projections to the bed nucleus of the stria terminalis.

The medial amygdala (MeA) controls several types of social behavior via its projections to other limbic regions. Cells in the posterior dorsal and posterior ventral medial amygdala (MePD and MePV, respectively) project to the bed nucleus of the stria terminalis (BNST) and these pathways respond to chemosensory cues and regulate aggressive and defensive behavior. Because the BNST is also essential for the display of stress-induced anxiety, a MePD/MePV-BNST pathway may modulate both aggression and responses to stress.
