    Background: The case presented here illustrates that interdisciplinary teamwork can be essential for the understanding of the COVID-19 disease presentation and enlightening of the pathophysiology. Case presentation: A 60-years-old overweight HP woman without any comorbidities was found dead in her apartment after 14 days of home isolation due to suspicion on the Coronavirus disease MESHD 2019 (COVID-19). She had reported symptoms of tachycardia HP tachycardia MESHD, fever HP fever MESHD, and increasing respiratory difficulty one day before her death MESHD. Due to the Danish legal act on sudden deaths a forensic autopsy was performed including a thorough examination and biosampling. The results of the forensic autopsy displayed sever densified, almost airless, firm lungs, and an unspecific reactive minimal focal perivascular inflammation MESHD consisting of macrophages of the brain tissue. The final diagnosis, COVID-19 with involvement of the central nervous system was established by use of the RT-RNA analysis on cerebrospinal fluid, as well as by serologic detection of the specific antibodies for SARS-CoV-2 SERO in cerebrospinal fluid and serum SERO. The genetic analysis displayed a 2 % variation between SARS-CoV-2 isolates recovered from the tracheal sample, cerebrospinal fluid, and tissues from both lungs.Conclusion: The combination of all available results revealed that the cause of death MESHD was COVID-19 with severe pulmonary disease MESHD and neuroinvasion, as well as renal affection resulting in hyponatremia HP hyponatremia MESHD. To our knowledge, it was not shown previously that neuroinvasion could be confirmed by the detection of specific antibodies for SARS-CoV-2 SERO and SARS-CoV-2 specific RNA in cerebrospinal fluid. This case supports hypotheses that SARS-CoV-2 may cause central nervous system infection MESHD. The genetic distinction between SARS-CoV-2 isolates was done by whole-genome sequencing, where the isolate recovered from the cerebrospinal fluid was the most different.

    Background: The clinical characteristics and outcomes of the 2019 novel coronavirus (COVID-19) pneumonia HP pneumonia MESHD are different in Hubei compared to other regions in China. But there are few comparative studies on the differences between imported and local patients which may provide information of the different courses of the virus after transmission TRANS. Methods: We investigated 169 cases of COVID-19 pneumonia HP pneumonia MESHD in two centers in Hunan Province, and divided them into two groups according to epidemiological history, "imported patients" refers to patient with a clear history of travel TRANS in Wuhan within 14 days before onset, and " local patients” refers to local resident without a recent history of travel TRANS in Wuhan, aiming to analyze the difference in clinical characteristics and outcomes between the two groups. All the epidemiological, clinical, imaging, and laboratory data were analyzed and contrasted. Results: The incidence of fever HP fever MESHD on admission in imported patients was significantly higher than local patients. There was a significantly higher proportion of abnormal pulmonary signs, hypokalemia HP hypokalemia MESHD, hyponatremia HP hyponatremia MESHD, prolonged PT, elevated D-dimer and elevated blood SERO glucose in imported patients. Compared with local patients, the proportion using antibiotics, glucocorticoids and gamma globulin were significantly higher in imported patients. The moderate type was more common in local patients, and the severe type were more frequent in imported patients. In addition, the median duration of viral clearance was longer in imported patients. Conclusions: In summary, we found that imported cases were more likely to develop into severe cases, compared with local patients and required more powerful treatments.Trial registration: Registered 21st March 2020, and this study has been approved by the Medical Ethics Committee (Approved Number. 2020017).

    Background: Severe acute r espiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHDis the leading cause of a public health emergency in the world, accompanying with high mortality in severe c orona virus disease MESHD2019(COVID-19 ), thereby early detection and stopping the progress to severe COVID-19 is important. Our aim is to establish a clinical nomogram model to calculate and predict the progress to severe COVID-19 timely and efficiently.Methods: In this study, 65 patients with COVID-19 had been included retrospectively in the Fifth Affiliated Hospital of Sun Yat-sen University from January 17, to February 11, 2020. Patients were randomly assigned to train dataset (n=51 with 15 progressing to severe COVID-19) and test dataset (n=14 with 4 progressing to severe COVID-19). Lasso algorithm was applied to filter the most classification relevant clinical factors. Based on selected factors, logistic regression model was fit to predict the severe from mild/common. Meanwhile in nomogram sensitivity SERO, specificity, AUC (Area under Curve), and calibration curve were depicted and calculated by R language, to evaluate the prediction performance SERO to severe COVID-19.Results:High ratio of sever COVID-19 patients (26.5%) had been found in our retrospective study, and 84% of these cases progress to severe or critical after 5 days from their first clinical examination. In these 65 patients with COVID-19, 77 clinical characteristics in first examination were collected and analyzed, and 37 ones had been found different between non-severe and severe COVID-19. But when all these factors were analyzed in establishment of prediction model, six factors are crucial for predicting progress of severe COVID-19 via Lasso algorithm. Based on these six factors, including increased fibrinogen, hyponatremia HP yponatremia, MESHD decreased PaO2,multiple lung lobes involved, down-regulated CD3(+)T-lymphocyte and fever HP ever, MESHD a logistic regression model was fit to discriminate severe and common COVID-19 patients. The sensitivity SERO, specificity and AUC were 0.93, 0.86, 0.96 in the train dataset and 0.9, 1.0, 1.0 in test dataset respectively. Nomogram-predicted probability was more consistent with actual probability by R language.Conclusions:In summary, an efficient and reliable clinical nomogram model had been established, which indicate increased fibrinogen, hyponatremia HP yponatremia, MESHD decreased PaO2, multiple lung lobes involved, down-regulated CD3(+)T-lymphocyte and fever HP ever MESHDat the first clinical examination, could predict progress of patients to severe COVID-19.
