    Background COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia. Methods We conducted a multicenter retrospective study and reviewed 517 patients admitted due to COVID-19 pneumonia who were hypoxemic and administered steroids regarding demographic, laboratory, and radiological characteristics, treatment response, and mortality-associated factors. Results Of our 517 patients with COVID-19 pneumonia who were hypoxemic and received corticosteroids, the mortality rate was 24.4% (n = 126). The evaluation of mortality-associated factors revealed that age, comorbidities, a CURB-65 score of >= 2, higher SOFA scores, presence of MAS, high doses of steroids, type of steroids, COVID-19 treatment, stay in the intensive care unit, high levels of d-dimer, CRP, ferritin, and troponin, and renal dysfunction were associated with mortality. Conclusion Due to high starting and average steroid doses are more associated with mortality, high-dose steroid administration should be avoided. We believe that knowing the factors associated with mortality in these cases is essential for close follow-up. The use of CURB-65 and SOFA scores can predict prognosis in COVID-19 pneumonia.

    Objective: The aim of this study is to investigate the effect of asbestos exposure on cancer-driver mutations. Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded. Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.5%, 3.7%, and 0.9%, respectively. The rates of EGFR mutations and ALK rearrangements were more frequent in asbestos exposed non-smokers (48.7% and 9%, respectively). EGFR mutation rate was correlated to female gender and not-smoking, ALK rearrangement rate was correlated to younger age, not-smoking, and a history of asbestos exposure. Conclusions: The higher rate of ALK rearrangements in asbestos-exposed lung adenocarcinoma cases shows that asbestos exposure may most likely cause genetic alterations that drive pulmonary adenocarcinogenesis.
