    Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-Cov-2), has developed into a global health crisis. Understanding the risk factors for poor outcomes of COVID-19 is thus important for successful management and control of the pandemic. However, the progress and severity of the epidemic across different regions show great differentiations. We hypothesized the origination of these differences are based on location-dependent variations in underlying population-wide health factors. Disease prevalence SERO or incidence data of states and counties of the United States were collected for a group of chronic diseases MESHD, including hypertension HP hypertension MESHD, diabetes MESHD, obesity HP obesity MESHD, stroke HP stroke MESHD, coronary heart disease MESHD, heart failure MESHD, physical inactivation, and common cancers MESHD (e.g., lung, colorectal MESHD, stomach, kidney and renal MESHD). Correlation and regression analysis identified the prevalence SERO of heart failure MESHD as a significant positive factor for region-level COVID-19 mortality. Similarly, the incidence of gastric cancer MESHD and thyroid cancer MESHD were also identified as significant factors contributing to regional variation in COVID-19 mortality. To explore the implications of these results, we re-analyzed the RNA-seq data for stomach adenocarcinoma MESHD ( STAD MESHD) and colon carcinoma MESHD carcinoma HP ( COAD MESHD) from The Cancer Genome Atlas (TCGA) project. We found that expression of genes in the immune response pathways were more severely disturbed in STAD MESHD than in COAD, implicating higher probability for STAD MESHD patients or individuals with precancerous chronic stomach diseases MESHD to develop cytokine storm once infected with COVID-19. Taken together, we conclude that location variations in particular chronic diseases MESHD and cancers MESHD contribute significantly to the regional variations in COVID-19 mortality.

    Background: In high COVID-19 prevalence SERO region, COVID-19 disease may be incidental found in non-specific symptoms or asymptomatic TRANS patient with history of tumor MESHD who underwent 18F-FDG-PET/CT for standard oncologic indications.Case presentation: A 51-year-old woman with a 4-year history of adenoid cystic carcinoma of nasal cavity MESHD carcinoma HP of nasal cavity underwent 18F-FDG PET/CT for restaging during COVID-19 outbreak in Wuhan. Pneumonia HP Pneumonia MESHD lesions were characterized by 18F-FDG uptake ground-glass opacities (GGOs) and multifocal high 18F-FDG-avid patchy consolidation, and without lymph node involvement and pleural effusion HP pleural effusion MESHD. Furthermore, multiple 18F-FDG-positive lung and lumbar metastases MESHD were observed. Finally, a diagnosis of COVID-19 was made based on a positive real-time fluorescent polymerase chain reaction (RT-PCR) test of SARS-CoV-2 nucleic acid. Conclusion: The non-specific symptoms or asymptomatic TRANS cancer MESHD patients presenting 18F-FDG-positive GGOs and patchy consolidation lesions in lung may favor COVID-19, who should be quickly SARS-CoV-2 nucleic acid tested and monitored.
