Introduction: This study aimed to explore the factors influencing people's utilization of ride-hailing services, particularly in the context of the COVID-19 pandemic., Methods: A two-stage survey was conducted among the same group of passengers pre and post COVID-19 pandemic, resulting in a total of 670 valid samples. Exploratory factor analysis (EFA) was applied to the data, followed by the ordered probit and ordered logit models to identify the motivational factors behind passengers' frequency of using ride-hailing., Results: The findings indicated that trust and loyalty were the most influential factors in determining passengers' frequency of using ride-hailing services. However, passengers' perception of the COVID-19 pandemic did not have a significant effect on the frequency of using ride-hailing., Discussion: This research provides empirical evidence and policy implications for understanding people's usage of the ride-hailing services in the context of public-health emergency., Competing Interests: TZ was employed by TOEC Technology Co., Ltd. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Ling, Jia, Yuan, Dong and Zhang.)

Purpose: This paper was intended to describe the characteristics of coronavirus disease 2019 (COVID-19) patients with known chronic kidney disease (CKD) history., Methods: Clinical information of 20 COVID-19 pneumonia patients with CKD history diagnosed between January 20th and March 1st, 2020 were collected in Tongji Hospital, Wuhan. We listed the clinical baseline data, laboratory findings, chest computed tomography (CT) changes and processed a short period of follow-up of these 20 patients., Results: Based on the estimated glomerular filtration rate (eGFR) on admission, 6 patients were classified as stage 2 of CKD, 5 were as 3a, 2 were as 3b, 3 were as 4 and 4 were as 5, respectively. COVID-19 patients with CKD history were elder and hypertension was the most common comorbidity. Cough and fever accounted for more than 80% of the infectious cases. Lymphopenia, increased D-dimer and elevated infectious indications such as hypersensitive C response protein (hsCRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were also common among these patients. Ground-glass opacity (GGO) and consolidation were the major manifestations in CT scans. 4 patients died and 7 patients underwent acute kidney injury (AKI) during observation. Among 16 discharged patients, 12 were with stable renal function and 4 had deteriorating renal function compared with that of admission., Conclusion: Compared to general population infected with SARS-CoV-2, COVID-19 patients with CKD history had a preference to develop to severity with higher fatality rate., (© 2021.

Pregnant women with 2019 novel coronavirus disease (COVID-19) pneumonia are a special group of patients in the pandemic. We report a case of pregnant woman with COVID-19 pneumonia in the second trimester. Clinical and imaging features of the patient were similar to that reported in the literatures for both perinatal patients and non-pregnant patients., (Copyright © 2020 Elsevier Inc.
