RESUMEN
We aim to assess physicians' level of resilience and define factors that improve or decrease the resilience level during the COVID-19 pandemic. Physicians from hospitals located in areas with different COVID-19 caseload levels, were invited to participate in a national e-survey between April and May 2020. Study participants were mainly emergency physicians, and anaesthesiologists, infectious disease consultants, and intensive care. The survey assessed participant's characteristics, factors potentially associated with resilience, and resilience using the Connor-Davidson Resilience Scale (RISC-25), with higher scores indicative of greater resilience. Factors associated with the resilience score were assessed using a multivariable linear regression. Of 451 responding physicians involved in the care of COVID-19 patients, 442 were included (98%). Age was 36.1 ± 10.3 years and 51.8% were male; 63% worked in the emergency department (n = 282), 10.4% in anesthesiology (n = 46), 9.9% in infectious disease department (n = 44), 4.8% in intensive care unit (n = 21) or other specialties (n = 49). The median RISC-25 score was at 69 (IQR 62-75). Factors associated with higher RISC scores were anesthesia as a specialty, parenthood, no previous history of anxiety or depression and nor increased anxiety. To conclude, this study is the first to characterize levels of resilience among physicians involved in COVID-19 unit. Our data points to certain protective characteristics and some detrimental factors, such as anxiety or depression, that could be amenable to remediating or preventing strategies to promote resilience and support caregivers in a pandemic.

BACKGROUND: A biological concentrate was produced from cultures of an Avène aquatic microflora isolate, namely Aquaphilus dolomiae. Some of the beneficial effects on diseased and damaged skin are thought to be due to the presence of this microorganism. AIMS: An extract of A. dolomiae (A. dolomiae extract-G2, ADE-G2) was evaluated for its wound-healing effects using in vitro and ex vivo models of injured skin. METHODS: The effect of ADE-G2 on the proliferation of fibroblasts, migration of keratinocytes and re-epithelialization of ex vivo wounded skin explants was measured. Antimicrobial protection by ADE-G2 was measured by analysing the gene expression of a panel of antimicrobial proteins (AMPs) in keratinocytes (RNASE7, S100A7, DEFB4A/B and DEFb103B), as well as the protein encoded by DEFB4A-B (hBD2) in the medium. RESULTS: ADE-G2 increased fibroblast proliferation and keratinocyte migration, as well as re-epithelialization of wounded ex vivo skin. ADE-G2 induced the expression of all AMP genes analysed in keratinocytes, as well as stimulated the release in to the medium of hBD2 peptide, encoded by DEFB4A/B. CONCLUSIONS: We have shown the broad spectrum of the repairing properties of the A. dolomiae extract, ADE-G2. These results support the use of ADE-G2 as a promising component for use in formulations aimed at repairing skin, limiting wound superinfection and preventing complicated wounds.
