Epidemiology, diagnosis and treatment of early COVID-19 patients in Jiaxing City, Zhejiang Province, China, January to March 2020.

BACKGROUND: Imported Coronavirus disease 2019 (COVID-19) patients pose a huge challenge to the prevention and control of the epidemic in prefecture-level cities in China. However, the treatment strategies at that time were mainly empirical and far from perfect. Hence, this study aims to summarize the clinical characteristics, diagnosis and treatment of all COVID-19 patients in Jiaxing City in 2020. METHODS: The clinical data of 42 patients diagnosed with COVID-19 in Jiaxing City, Zhejiang Province from January 23, 2020 to March 4, 2020 were retrospectively analyzed. Epidemiological history and sociodemographic data were collected. Laboratory parameters, imaging and disease progression, treatment methods, efficacy and adverse reactions of COVID-19 cases were recorded. Then, the clinical characteristics as well as diagnosis and treatment were statistically analyzed. RESULTS: The median age of 42 patients was 47 years old, including 24 males (57.1%) and 18 females (42.9%). There were 21 first-generation cases, 29 cases (69%) of clustering onset related to first-generation cases, and 28 cases without any underlying diseases. Radiographic progression was reported in 17 patients (40.5%) (progression duration, 2-11 days; median progression duration, 3.8 days; average progression duration, 4.59-2.48 days). The main clinical symptoms include fever (78.6%) and cough (64.3%). A total of 37 patients (88.10%) received arbidol combined with lopinavir/ritonavir or darunavir/cobicistat. Of these, 22 patients (52.4%) took a combination with moxifloxacin tablets, and 20 patients (47.6%) took combined hormone therapy. Seventeen patients (40.48%) reported diarrhea, nausea, vomiting, rash, and other adverse drug reactions. A total of 38 patients improved (90.5%). The hospital stays of 36 patients ranged from 7 to 33 days, with a median of 19 days (19.00-7.33 days on average). The virus nucleic acid test result return time was 1 to 32 days, with a median of 15.5 days (14.41-8.61 days on average). CONCLUSIONS: Most of the imported COVID-19 patients in Jiaxing City were of the first generation, mainly cluster onset, and the epidemiological characteristics were relatively simple. Arbidol combined with lopinavir/ritonavir or darunavir/cobicistat was the main treatment strategy for the initial treatment of COVID-19.

China economic performance and natural resources commodity prices volatility: Evidence from China in COVID-19.

Since the beginning of the 21st century, the world has faced many challenges, including the 2003 oil price hike, the 2007-08 global financial crisis, among others. While the recent Covid-19 outbreak slowdown economic performance and create uncertainty in natural resources commodity prices, which brought the attention of academic research. Current study examined economic performance and natural resource commodity price volatility in China over the period 1990-2020. Also, this study considers the role of renewable energy investment, renewable electricity output, and green finance in the pre and post Covid-19 pandemic periods. For empirical investigation, this study employed dynamic ordinary least square (DOLS), fully modified ordinary least square (FMOLS), and Canonical Cointegrating Regression (CCR). The outcomes reveal that the first-differenced stationary variables are all cointegrated in the long run. While these estimators confirmed that natural resources commodity price volatility negatively affects economic performance. Besides, the results validate the positive impact of renewable energy investment, renewable electricity output, and green finance on economic performance. The results are found robust and consistent, justified by Robust regression. These findings could have essential economic, natural resources, and energy implications for policymakers, governors, and researchers.

Obesity as a Potential Predictor of Disease Severity in Young COVID-19 Patients: A Retrospective Study.

OBJECTIVE: This study aims to explore the indicators for severity of coronavirus disease 2019 (COVID-19) in young patients between the ages of 18 and 40 years. METHODS: This retrospective cohort study included 65 consecutively admitted patients with COVID-19 who were between 18 and 40 years old in Zhongnan Hospital of Wuhan University in Wuhan, China. Among them, 53 were moderate cases, and 12 were severe or critical cases. Epidemiological, clinical, and laboratory characteristics and treatment data were collected. A multivariate logistic regression analysis was implemented to explore risk factors. RESULTS: The patients with severe/critical cases had obviously higher BMI (average 29.23 vs. 22.79 kg/m2 ) and lower liver computed tomography value (average 50.00 vs. 65.00 mU) than the group of moderate cases. The patients with severe/critical cases had higher fasting glucose, alanine aminotransferase, aspartate aminotransferase, and creatinine compared with patients with moderate cases (all P < 0.01). More severe/critical cases (58.33% vs. 1.92%) had positive urine protein levels. The severe/critical cases also experienced a significant process of serum albumin decline. Logistic regression analysis showed that male sex, high BMI (especially obesity), elevated fasting blood glucose, and urinary protein positivity were all risk factors for young patients with severe COVID-19. CONCLUSIONS: Obesity is an important predictor of COVID-19 severity in young patients. The main mechanism is related to damage of the liver and kidney.

The prevention and management of the coronavirus disease 2019 (COVID-19) outbreak in radiology departments in epidemic areas.

This review based on the actual results of epidemic prevention management in radiology departments in epidemic areas, and using designated hospital management methods, to summarize the radiology protection system. With the cooperation of the whole hospital and radiology department, a number of effective evaluation methods have been carried out to ensure the optimization of clinical protection. These practical methods provide a basis for the further promotion of management strategies and reduction of nosocomial infection. To our knowledge, the establishment of standardized protection and clear process has opened up a new idea of epidemic prevention management, which can effectively provide timely, efficient, and accurate support for clinical research, and promote the transformation from clinical research type to scientific research management type.
