Challenges in Recruiting, Retaining and Promoting Racially and Ethnically Diverse Faculty.

BACKGROUND: Despite individual and institutional awareness of the inequity in retention, promotion and leadership of racially and ethnically underrepresented minority faculty in academic medicine, the number of such faculty remains unacceptably low. The authors explored challenges to the recruitment, retention and promotion of underrepresented faculty among a sample of leaders at academic medical centers. METHODS: Semi-structured interviews were conducted from 2011 to 2012 with 44 senior faculty leaders, predominantly members of the Group on Diversity and Inclusion (GDI) and/or the Group on Women in Medical Sciences (GWIMS), at the 24 randomly selected medical schools of the National Faculty Survey of 1995. All institutions were in the continental United States and balanced across public/private status and geographic region. Interviews were audio-taped, transcribed, and organized into content areas before conducting inductive thematic analysis. Themes expressed by multiple informants were studied for patterns of association. RESULTS: The climate for underrepresented minority faculty was described as neutral to positive. Three consistent themes were identified regarding the challenges to recruitment, retention and promotion of underrepresented faculty: 1) the continued lack of a critical mass of minority faculty; 2) the need for coordinated programmatic efforts and resources necessary to address retention and promotion; and 3) the need for a senior leader champion. CONCLUSION: Despite a generally positive climate, the lack of a critical mass remains a barrier to recruitment of racially and ethnically underrepresented faculty in medicine. Programs and resources committed to retention and promotion of minority faculty and institutional leadership are critical to building a diverse faculty.

Overt and latent cardiac effects of ozone inhalation in rats: evidence for autonomic modulation and increased myocardial vulnerability.

BACKGROUND: Ozone (O3) is a well-documented respiratory oxidant, but increasing epidemiological evidence points to extrapulmonary effects, including positive associations between ambient O3 concentrations and cardiovascular morbidity and mortality. OBJECTIVE: With preliminary reports linking O3 exposure with changes in heart rate (HR), we investigated the hypothesis that a single inhalation exposure to O3 will cause concentration-dependent autonomic modulation of cardiac function in rats. METHODS: Rats implanted with telemeters to monitor HR and cardiac electrophysiology [electrocardiography (ECG)] were exposed once by whole-body inhalation for 4 hr to 0.2 or 0.8 ppm O3 or filtered air. A separate cohort was tested for vulnerability to aconitine-induced arrhythmia 24 hr after exposure. RESULTS: Exposure to 0.8 ppm O3 caused bradycardia, PR prolongation, ST depression, and substantial increases in atrial premature beats, sinoatrial block, and atrioventricular block, accompanied by concurrent increases in several HR variability parameters that were suggestive of increased parasympathetic tone. Low-O3 exposure failed to elicit any overt changes in autonomic tone, heart rhythm, or ECG. However, both 0.2 and 0.8 ppm O3 increased sensitivity to aconitine-induced arrhythmia formation, suggesting a latent O3-induced alteration in myocardial excitability. CONCLUSIONS: O3 exposure causes several alterations in cardiac electrophysiology that are likely mediated by modulation of autonomic input to the heart. Moreover, exposure to low O3 concentrations may cause subclinical effects that manifest only when triggered by a stressor, suggesting that the adverse health effects of ambient levels of air pollutants may be insidious and potentially underestimated.
