RESUMO

Background: With more than 50% of anesthesiology residents reporting burnout, many residency programs have begun creating wellness programs to address burnout and promote well-being. However, to date, many wellness initiatives have focused on individual strategies rather than systems approaches to improve the learning environment. Individual-focused interventions in the absence of systematic efforts can lead to resentment, resistance, and worsening burnout and precipitate a loss of trust in leadership and the organization. Here, we describe a process to engage anesthesiology residents, who are key stakeholders, by exploring their perspectives on burnout and well-being to better inform systematic interventions to improve the clinical work and learning environments. Methods: We conducted semistructured interviews with second- and third-year clinical anesthesia residents at the University of California, San Francisco, using the areas of worklife model as sensitizing concepts. We conducted a thematic analysis on transcribed interviews grounded in constructivist orientation. Results: We identified the following 3 major categories of themes based on interviews with 10 residents: (1) definition of well-being, (2) challenges to well-being, and (3) strategies for coping with challenges and burnout. Challenges described by anesthesiology residents align with the areas of the worklife model, with the coronavirus disease 2019 pandemic precipitating additional threats in the domains of workload and community. Conclusions: Anesthesiology residents' definition of well-being includes both individual (resilience) and systemic (meaning in work, job autonomy, and control) factors, reaffirming that positive work and learning environments are critical to professional well-being.

RESUMO

FlhDC is a heterohexameric complex that acts as a master regulator of flagellar biosynthesis genes in numerous bacteria. Previous studies have identified a single flhDC operon encoding this complex. However, we found that two flhDC loci are present throughout Paraburkholderia, and two additional flhC copies are also present in Paraburkholderia unamae. Systematic deletion analysis in P. unamae of the different flhDC copies showed that one of the operons, flhDC1, plays the predominant role, with deletion of its genes resulting in a severe inhibition of motility and biofilm formation. Expression analysis using promoter-lacZ fusions and real-time quantitative PCR support the primary role of flhDC1 in flagellar gene regulation, with flhDC2 a secondary contributor. Phylogenetic analysis shows the presence of the flhDC1 and flhDC2 operons throughout Paraburkholderia. In contrast, Burkholderia and other bacteria only carry the copy syntenous with flhDC2. The variations in impact each copy of flhDC has on downstream processes indicate that regulation of FlhDC in P. unamae, and likely other Paraburkholderia species, is regulated at least in part by the presence of multiple copies of these genes. IMPORTANCE Motility is important in the colonization of plant roots by beneficial and pathogenic bacteria, with flagella playing essential roles in host cell adhesion, entrance, and biofilm formation. Flagellar biosynthesis is energetically expensive. Its complex regulation by the FlhDC master regulator is well studied in peritrichous flagella expressing enterics. We report the unique presence throughout Paraburkholderia of multiple copies of flhDC. In P. unamae, the flhDC1 copy showed higher expression and a greater effect on swim motility, flagellar development, and regulation of downstream genes, than the flhDC2 copy that is syntenous to flhDC in Escherichia coli and pathogenic Burkholderia spp. The flhDC genes have evolved differently in these plant-growth-promoting bacteria, giving an additional layer of complexity in gene regulation by FlhDC.
