A predictive model for respiratory distress in patients with COVID-19: a retrospective study.

BACKGROUND: Coronavirus disease 2019 (COVID-19), associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global public health crisis. We retrospectively evaluated 863 hospitalized patients with COVID-19 infection, designated IWCH-COVID-19. METHODS: We built a successful predictive model after investigating the risk factors to predict respiratory distress within 30 days of admission. These variables were analyzed using Kaplan-Meier and Cox proportional hazards (PHs) analyses. Hazard ratios (HRs) and performance of the final model were determined. RESULTS: Neutrophil count >6.3×109/L, D-dimer level ≥1.00 mg/L, and temperature ≥37.3 °C at admission showed significant positive association with the outcome of respiratory distress in the final model. Complement C3 (C3) of 0.9-1.8 g/L, platelet count >350×109/L, and platelet count of 125-350×109/L showed a significant negative association with outcomes of respiratory distress in the final model. The final model had a C statistic of 0.891 (0.867-0.915), an Akaike's information criterion (AIC) of 567.65, and a bootstrap confidence interval (CI) of 0.866 (0.842-0.89). This five-factor model could help in early allocation of medical resources. CONCLUSIONS: The predictive model based on the five factors obtained at admission can be applied for calculating the risk of respiratory distress and classifying patients at an early stage. Accordingly, high-risk patients can receive timely and effective treatment, and health resources can be allocated effectively.

Interventional radiology under the era of coronavirus disease 2019: Recommendations from the Chinese College of Interventionalists.

The pandemic of coronavirus disease 2019 (COVID-19) has become a major public health threat to the whole world. Although the control of COVID-19 has been in the forefront of interventional practice, most interventional radiologists (IRs) are not equipped adequately to cope with such a crisis. In this review, we share our experience from Chinese IRs' perspective, report on the acute measures instituted within interventional radiology (IR) units, and give recommendations to the prevention and control of COVID-19.

Chinese Society of Interventional Radiology Expert Consensus on the prevention and control of COVID-19 in interventional radiology procedures (first edition).

The COVID-19 pandemic seriously threatens the lives of the general public and poses momentous challenges to all medical workers, including those engaged in interventional radiology, who play an important role in the diagnosis and treatment of various diseases. To further standardize the prevention and control of nosocomial infections and ensure the safety of doctors and patients, the Chinese Society of Interventional Radiology (CSIR) organized multidisciplinary experts in the field of interventional radiology in China to prepare an "Expert Consensus" elaborating and summarizing the protective strategies and suggestions for medical workers in the field of interventional radiology when they engage in interventional diagnosis and treatment activities against the background of novel coronavirus infection control. The aim is to provide a reference for interventional procedures in hospitals and other medical institutions at all levels in China and worldwide. The key points include the following: (I) non-emergency interventional diagnosis and treatment should be suspended while work is ongoing to prevent and control the spread of COVID-19; (II) protective measures should be taken according to the appropriate level designated for COVID-19 infection prevention and control; (III) patients should take measures to protect themselves when they want to see a doctor, including accessing outpatient services online and other relevant channels of consultation.

CSCO ablation expert workshop report: Recommendations for the management of tumor ablation during the coronavirus disease 2019 epidemic.

The coronavirus disease 2019 (COVID-19) has become a global pandemic since its outbreak in December 2019, which posed a threat to the safety and well-being of people on a global scale. Cancer patients are at high risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and their critical morbidity and case fatality rates are high. The ablation expert committee of the Chinese Society of Clinical Oncology compiled corresponding expert recommendations. These recommendations summarize the preventive measures and management of tumor ablation treatment in medical institutions, including outpatient clinics, oncology wards, ablation operation room, and postablation follow-ups in accordance with the guidelines and protocols imposed by the National Health Commission of the People's Republic of China and the experience in management and prevention according to various hospitals. This consensus aims to reduce and prevent the spread of SARS-CoV-2 and its cross-infection between cancer patients in hospitals and provide regulatory advice and guidelines for medical personnel.
