Chiropractic faculty experiences of burnout and the COVID-19 pandemic.

OBJECTIVE: The Maslach Burnout Inventory (MBI) is frequently used to assess occupational burnout and the Epidemic-Pandemic Impacts Inventory (EPII) is a new tool for assessing pandemic impacts. This study's objective is to describe chiropractic faculty members' experience of the COVID-19 pandemic, their burnout as professional educators, and their strategies for coping with stress. METHODS: A Qualtrics survey link was emailed to 73 current faculty and 10 previously employed faculty from 1 chiropractic school. The survey included 22 MBI, 31 EPII, and 2 questions about coping strategies. Faculty were given several weeks to complete the survey, were reminded via emails and meeting announcements, and were given paper surveys to increase participation. Responses were analyzed in STATA17. RESULTS: Forty-three faculty completed the survey (response rate = 52%). Of these, 25.8% reported testing positive for COVID-19, 30.23% reported difficulties transitioning to working from home, and 25.5% scored high on the MBI subscale for emotional exhaustion (EE) (mean 15.79, SD 13.68). Higher EE was associated with pandemic-related increases in mental health and sleep problems. Common coping strategies included self-care and social support. CONCLUSION: The majority of faculty reported neither contracting COVID-19 nor having difficulty transitioning to work from home. Average EE for participating faculty was lower than previous reports although a quarter scored high in EE, which may be associated with pandemic-related mental health and sleep problems. These results suggest chiropractic faculty might need support coming out of the COVID-19 pandemic and indicate the need for future research on burnout among faculty from other chiropractic institutions.

Nickel(II) complexes stabilized by bis[N-(6-pivalamido-2-pyridylmethyl)]benzylamine: Synthesis and characterization of complexes stabilized by a hydrogen bonding network.

Hydrogen bonds in metalloproteins are key in directing reactivity yet to be achieved in synthetic systems. We have been developing a synthetic system that uses hydrogen-bonding interactions to modulate the secondary coordination around a transition metal ion. This was accomplished with the ligand bis[N-(6-pivalamido-2-pyridylmethyl)]benzylamine (H(2)pmb), which contains two carboxyamido units appended from pyridine rings. Several nickel complexes were prepared and structurally characterized. In particular, we found that the appended carboxyamido groups either provide intramolecular H-bond donors or can be converted to bind directly to a metal center. We established that the complex Ni(II)H(2)pmb(Cl)(2) can be sequentially deprotonated with potassium tert-butoxide, causing coordination of the carboxyamido oxygen atoms and concomitant loss of the chloro ligands. The chloro ligands were also removed with silver(I) salts-in the presence of acetate ions, the complex Ni(II)H(2)pmb(κ(2)-OAc)(κ(1)-OAc) was isolated, in which an intramolecular H-bonding network occurs between the H(2)pmb ligand and the coordinate acetato ligands.
