ABSTRACT

Objectives: To provide a reference for CT imaging changes for patients discharged from a Fangcang shelter hospital, a large-scale, temporary hospital for the centralized treatment of patients with mild to moderate Coronavirus disease 2019 (COVID-19) to provide essential functions (isolation, triage, basic medical care, frequent monitoring and rapid referral, essential living and social engagement) to them.. Methods: : Patients with mild to moderate COVID-19 admitted to the Wuchang Fangcang Shelter Hospital who had undergone pre-discharge and previous CT scans were included. Changes in the CT imaging features were defined as progression, no change, improvement or recovery. Basic patient information was obtained, and imaging signs were compared between the two CT scans. Results: : A total of 83 patients were included. The median age was 53 years old. The course of disease was 28.3±10.7 days. CT imaging changes indicated progression, no change, improvement, and recovery in 3, 12, 66, and 2 patients, respectively. Between the two CT scans, the imaging signs showed a significant reduction in consolidation, a significant increase in fibrosis, and a reduction or / and thinning of ground-glass opacities. None of the patients showed signs of deterioration on follow-up and thus did not need to return to the hospital for treatment. Conclusion: In the COVID-19 Fangcang shelter hospital, given the shortage of medical staff and lack of medical resources, CT imaging diagnostic methods can be used to accurately discharge patients who had met the discharge criteria for isolation and observation from the Fangcang Shelter Hospital.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is a highly contagious respiratory disease that threatens global health. During the pandemic period of COVID-19, the task for prevention in the general ward of cardiovascular surgery is fairly arduous. The present study intends to summarize our experience with infection control, including ward setting, admission procedures, personnel management, health education, and so on, to provide references for clinical management.

ABSTRACT

BACKGROUNDMultisystem inflammatory syndrome in children (MIS-C) is a rare but potentially severe illness that follows exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Kawasaki disease (KD) shares several clinical features with MIS-C, which prompted the use of intravenous immunoglobulin (IVIG), a mainstay therapy for KD. Both diseases share a robust activation of the innate immune system, including the IL-1 signaling pathway, and IL-1 blockade has been used for the treatment of both MIS-C and KD. The mechanism of action of IVIG in these 2 diseases and the cellular source of IL-1ß have not been defined.METHODSThe effects of IVIG on peripheral blood leukocyte populations from patients with MIS-C and KD were examined using flow cytometry and mass cytometry (CyTOF) and live-cell imaging.RESULTSCirculating neutrophils were highly activated in patients with KD and MIS-C and were a major source of IL-1ß. Following IVIG treatment, activated IL-1ß+ neutrophils were reduced in the circulation. In vitro, IVIG was a potent activator of neutrophil cell death via PI3K and NADPH oxidase, but independently of caspase activation.CONCLUSIONSActivated neutrophils expressing IL-1ß can be targeted by IVIG, supporting its use in both KD and MIS-C to ameliorate inflammation.FUNDINGPatient Centered Outcomes Research Institute; NIH; American Asthma Foundation; American Heart Association; Novo Nordisk Foundation; NIGMS; American Academy of Allergy, Asthma and Immunology Foundation.

ABSTRACT

The outbreak of COVID-19 has had a huge impact on China’s economic and social development, among which the tertiary industry has been severely impacted. As the epidemic prevention and control in China has achieved initial success and entered the normal prevention and control stage, it is very necessary to analyze the damage situation of industries directly affected by the epidemic. According to the historical data of various industries in China in the past five years, a grey prediction model was established to predict the normal development law of some economic indicators without an epidemic situation. Compared with the actual values in the first two quarters of 2020, we can estimate the economic and social losses caused by the COVID-19 epidemic. The epidemic has had the most serious impact on the tertiary industry, with retail, tourism, and catering sectors were hit hard. With the effective control of the epidemic, China’s overall economic performance in the second quarter rose steadily. Many enterprises in the comprehensive service sector have been upgraded and transformed during the epidemic. From the current perspective, the epidemic will not have a serious impact on economic development throughout the year.
