RESUMEN
AIM(S): To describe a sample of healthcare professionals' responses to the valid and reliable Climate and Health Tool and compare participant characteristics relating to Climate and Health Tool subscales. DESIGN: Observational, cross-sectional, multi-site study. METHODS: An electronic survey containing the Climate and Health Tool was administered to healthcare professionals across a large, multi-state health system in the Western United States with a committed effort to reducing carbon emissions. RESULTS: One thousand three hundred and sixty-three participants reported moderately elevated levels of awareness and concern around climate impacts on health and motivation to participate in climate protective actions. Respondents reported moderate levels of climate-protecting behaviours at home and low levels at work. Females were more concerned and motivated. Medical staff and respondents reporting familiarity with system environmental initiatives reported more awareness and behaviours at home to preserve climate health. CONCLUSION: Healthcare professionals are concerned and motivated to decrease climate impacts on health yet take little action at work to preserve the climate. Because of the intersection of climate change, health, and healthcare, healthcare organizations should prioritize and support meaningful action for healthcare professionals to meet community climate health needs. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Healthcare organizations committed to contributing to climate solutions can use this research to increase healthcare professionals' education, engagement, and impact to preserve the climate and health of communities. IMPACT: Healthcare is a major contributor to carbon emissions, yet healthcare professionals' awareness, motivation, concern, and behaviours related to climate change and health were not clear. Our research showed healthcare professionals are aware and concerned about climate impacts on health but reported low levels of workplace behaviours to protect the climate. The findings of our research will impact healthcare professionals and healthcare organizations to focus efforts on climate-preserving behaviours. REPORTING METHOD: This manuscript followed the STROBE guidelines. PATIENT OR PUBLIC CONTRIBUTION: None.
RESUMEN
The protection of terrestrial plants from desiccation, mechanical injury, and pathogenic invasion is achieved by waxes and cutin polyesters on leaf and fruit surfaces as well as suberin polymers that are embedded in the cell walls of roots, but the physicochemical principles governing the organization of these biological composites remain incompletely understood. Despite the well-established enzymatic mediation of suberin formation in the skins of potato tubers, cork oak trees, and internal plant tissues, the additional possibility of self-assembly in this system was suggested by our serendipitous finding that solvent extracts from potato phellem tissues form suspended fibers and needles in the absence of such catalysts over a period of several weeks. In the current study, we investigated self-assembly for three-component model chemical mixtures comprised of a hydroxyfatty acid, glycerol, and either of two hydroxycinnamic acids that together typify the building blocks of potato suberin biopolymers. We demonstrate that these mixtures spontaneously form lamellar structures that are reminiscent of suberized plant tissues, incorporate all constituents into self-assemblies, can form covalently bound ester structures, and display antibacterial activity. These findings provide new perspectives on the self-association and reactivity of these classes of organic compounds, insights into agriculturally important suberin formation in food crops, and a starting point for engineering sustainable materials with antimicrobial capabilities.
