Breast Cancer Management During COVID-19 Pandemic in Madrid: Surgical Strategy

BackgroundFrom the first case of SARS-CoV-2 infection in Wuhan (China), the infection spread all around the world causing a pandemic of coronavirus disease-2019 (COVID-19). Spain has been one of the most severely affected countries, and Madrid has reported a high number of cases and deaths. We discuss our strategies for optimal breast cancer management during COVID-19 pandemic.Patients and MethodsThis was a retrospective observational study at Clínico San Carlos Hospital to analyze the management of patients with breast cancer during the pandemic outbreak and the surgical strategy after the pandemic outbreak. We created a practical and dynamic tool based on a “traffic light” system for prioritizing surgical time. Every patient was contacted by telephone with a preoperative COVID-19 protocol. After surgical procedures, patient satisfaction was assessed using the European Organisation for Research and Treatment of Cancer in-patient satisfaction with cancer care questionnaire (EORTC IN-PATSAT32).ResultsPatients with breast cancer actively treated with surgical procedures were put on a waiting list and received systemic therapy. Telemedicine was used to evaluate any side effects and to avoid unnecessary hospital visits. Surgery was only considered after the pandemic outbreak, and then, only those procedures designed to minimize surgical complications and, therefore, reduce hospital stay. We also measured patients’ satisfaction with medical and nursing scales that resulted in a “very good” evaluation tending to “excellent”.ConclusionIt is necessary to adapt management of oncology treatment and surgical strategy to optimize resources during the COVID-19 pandemic. Patients’ perception of care quality and the degree of patients’ satisfaction with health services has potential relevance in the absence of outcome data.     

TLR2 activation in corneal stromal cells by Staphylococcus aureus‐induced keratitis

The Toll‐Like Receptor 2 (TLR2) plays an active and important role in Staphylococcus aureus‐induced chronic ocular inflammation. The aim of this study was to investigate the expression and function of TLR2 of corneal stromal cells in ex vivo rabbit model of S. aureus keratitis. Corneal buttons with sclera rims placed in an ex vivo air‐interface organ culture were assigned to two groups: corneas with epithelial and stromal abrasions. Each group was then divided into two sub‐groups exposed to UV‐killed S. aureus ATCC 6538P and S. aureus ATCC 29213, respectively. TLR2 and IL‐8 mRNA expressions were analyzed by quantitative real‐time RT‐PCR. TLR2 localization was visualized by immunofluorescence analysis. The results demonstrated that TLR2 and IL‐8 mRNA were significantly expressed in the stromal cells of the groups exposed to S. aureus strains. Moreover, it has been demonstrated that, after corneal injury, keratocytes differentiated into myofibroblasts became able to express TLR2 only when exposed to S. aureus. Identification of mechanisms regulation of corneal TLRs may lead to development of therapeutic interventions aimed at controlling corneal inflammation. This ex vivo model can be used to clarify the molecular events of bacterial‐corneal tissue interactions and their inflammatory consequences.
