ABSTRACT
Crack cocaine has been associated with a variety of pulmonary manifestations. We report a 44-year-old man been diagnosed with severe acute respiratory syndrome coronavirus 2 infection, presenting shortness of breath, non-productive cough, chest pain, headache, dizzi-ness, and fever lasting for 2 days. At first, all findings of our patient called for an impression of coronavirus disease 2019. During admis-sion, he presented with acute respiratory symptoms, patchy ground-glass opacities, and laboratory abnormalities, such as elevated acute phase response and lymphopenia. After, the presence of transient lung infiltrations in the follow-up triggered the cause for a re-evaluation of the diagnosis of coronavirus disease 2019. After a detailed inquiry, it was revealed that he had had a history of intense inhaled cocaine use 2 days before hospitalization. We speculate that the crack lung should also be considered in the differential diagnosis in patients with suspected coronavirus disease 2019 pneumonia.Copyright © Author(s).
ABSTRACT
Introduction: Cancer patients are more sensitive to infections, and, compared to other patients, may have more serious outcomes. Thus, cancer patients are a high-risk group in the COVID-19 pandemic. The aim of this study was to evaluate how cancer patients are affected by COVID-19 infection;the prevalence, and factors affecting mortality. Methodology: This single-centre, retrospective study included cancer patients under follow-up treatment at our hospital with a laboratory-confirmed diagnosis of COVID-19. Demographic and clinical data were obtained from electronic medical records. The effects of tumour subtype and patient demographic data on COVID-19 prevalence and mortality were analyzed using univariate and multivariate models. Results: Evaluation was made of 217 cancer patients, comprising 140 (64.5%) males and 77 (35.5%) females with a mean age of 62.05 ± 12.95 years. Mortality was seen in 84 (38.7%) patients. Disease grade, chemotherapy within the last 3 months and CT findings were determined to be related to mortality. In logistic regression analysis, the most important factors affecting survival were determined to be severe lung involvement (p < 0.001) and hematological malignancy. Conclusions: It is clear that cancer patients are at greater risk from COVID-19 infection than individuals without a malignant disease. The results showed that cancer patients with different tumour types had different levels of sensitivity to COVID-19. It is clear that with ongoing viral mutations, the duration of the pandemic is unknown. Therefore, the continuation of cancer screening and cancer treatments should not be interrupted.

ABSTRACT
Objective: Pneumonia and acute respiratory distress syndrome are observed as major complications in Coronavirus disease-2019 (COVID-19). Cholesterol is a principal lipid component of the cell membranes. Lipoproteins have a fundamental role as the first line of defense against microbes. Lipoprotein levels are altered during viral infections. This study aimed to investigate the association between low-density lipoprotein cholesterol (LDL-C) levels and disease severity of patients hospitalized with COVID-19 pneumonia. Methods: This is a retrospective and observational study of 817 patients with Severe Acute Respiratory syndrome-Coronavirus-2 (SARS-CoV-2), who are diagnosed with COVID-19 using the real-time polymerase chain reaction and are hospitalized due to moderate and severe COVID-19 pneumonia. Results: Among 817 patients with COVID-19 pneumonia, 347 (42.5%) were moderate and 470 (57.5%) were severe. Total cholesterol (TC) and LDL-C levels reduced in patients who have severe condition than those with moderate condition (p=0.02, p=0.03, respectively). TC and LDL-C were negatively correlated with the hospitalization duration (r=-0.163, p=0.02, r=-0.154, p=0.03, respectively). Conclusion: Our results suggest a decreased LDL-C levels in patients with COVID-19 in relation to disease severity. Therefore, a strong link was found between lipid metabolism and SARS-CoV-2, which allow us to suggest LDL as a marker indicating COVID-19 severity in the near future.
