RESUMO
BACKGROUND: The arrival of the novel coronavirus (SARS-CoV-2) has impacted the many aspects of modern life, especially, in the immediate term, the delivery of healthcare. CONTEXT: This commentary examines the profession of podiatry and how it has adapted and responded to the emerging crisis. It focusses on but is not exclusive to the position in the United Kingdom (UK) and the edicts and direction from the UK Government. PODIATRY ROLES DURING THE PANDEMIC: It describes the role of podiatry in the pandemic and highlights the deployment of podiatry resources to fight the pandemic beyond traditional podiatric practice. It also looks at the shift from conventional consultation to digital solutions for managing patients in an effort to achieve the goals of maintenance of foot health whilst reducing the spread of the virus. The commentary summarises the emerging data related to a possible foot related presentation of the coronavirus. CONCLUSION: The podiatry profession proved its flexibility and adaptability during the pandemic, to adjust rapidly to ensure that patients were able to access treatment to reduce risk of infection, ulceration and amputation. Dermatological presentations on the feet have been associated with Covid-19 in adolescents as is often the case in viral infections. CPD webinars to support clinicians and manage and prevent the spread of Covid-19 have been widely disseminated along with algorithms to ensure that patients that need treatment are being treated appropriately. Podiatrists have embraced remote technology to ensure that patients are correctly and safely triaged and, signposted and given appropriate self-care advice. MSK podiatrists have the ability to play an intrinsic role within the post discharge rehabilitation pathway.

Resistance to platinum chemotherapy is a long-standing problem in the management of lung adenocarcinoma. Using a whole-genome synthetic lethal RNA interference screen, we identified activin signaling as a critical mediator of innate platinum resistance. The transforming growth factor-ß (TGFß) superfamily ligands activin A and growth differentiation factor 11 (GDF11) mediated resistance via their cognate receptors through TGFß-activated kinase 1 (TAK1), rather than through the SMAD family of transcription factors. Inhibition of activin receptor signaling or blockade of activin A and GDF11 by the endogenous protein follistatin overcame this resistance. Consistent with the role of activin signaling in acute renal injury, both therapeutic interventions attenuated acute cisplatin-induced nephrotoxicity, its major dose-limiting side effect. This cancer-specific enhancement of platinum-induced cell death has the potential to dramatically improve the safety and efficacy of chemotherapy in lung cancer patients.
