RESUMEN

In this study, we ascertained the chest CT data of 60 patients admitted to 3 hospitals in Chongqing with confirmed COVID-19. We conducted anatomical and pathological analyses to elucidate the possible reasons for the distribution, morphology, and characteristics of COVID-19 in chest CT. We also shared a semiquantitative scoring of affected lung segments, which was recommended by our local medical association. This scoring system was applied to quantify the severity of the disease. The most frequent imaging findings of COVID-19 were subpleural ground glass opacities and consolidation; there was a significant difference in semiquantitative scores between the early, progressive, and severe stages of the disease. We conclude that the chest CT findings of COVID-19 showed certain characteristics because of the anatomical features of the human body and pathological changes caused by the virus. Therefore, chest CT is a valuable tool for facilitating the diagnosis of COVID-19 and semiquantitative scoring of affected lung segments may further elucidate diagnosis and assessment of disease severity. This will assist healthcare workers in diagnosing COVID-19 and assessing disease severity, facilitate the selection of appropriate treatment options, which is important for reducing the spread of the virus, saving lives, and controlling the pandemic.

RESUMEN

Pulmonary embolisms (PEs) in coronavirus disease 2019 (COVID-19) have increasingly been reported in observational studies. However, limited information describing their clinical characteristics and outcomes exists. Our study aims to describe clinical features and risk stratification strategies of hospitalized COVID-19 patients with PE. We retrospectively analyzed 101 hospitalized patients with COVID-19 infection and acute PE. Clinical outcomes measured were intensive care unit admission, mechanical ventilation, bleeding and transfusion events, acute kidney injury (AKI) and mortality. Pulmonary severity index (PESI) scores were used for risk stratification. The most common comorbidities were hypertension (50%), obesity (27%) and hyperlipidemia (32%) among this cohort. Baseline D-dimer abnormalities (4,647.0 ± 8,281.8) were noted on admission with a 3-fold increase at the time of PE diagnosis (13,288.4 ± 14,917.9; p <0.05). Five (5%) patients required systemic thrombolysis and 12 (12%) patients experienced moderate to severe bleeding. Thirty-one (31%) patients developed AKI and 1 (1%) patient required renal replacement therapy. Twenty-three (23%) patients were admitted to intensive care unit, of which 20 (20%) patients received mechanical ventilation. The mortality rate was 20%. Most patients (65%) had Intermediate to high risk PESI scores (>85), which portended a worse prognosis with higher mortality rate and length of stay. In conclusion, this study provides characteristics and early outcomes for hospitalized patients with COVID-19 and acute pulmonary embolism. PESI scores were utilized for risk stratifying clinical outcomes. Our results should serve to alert the medical community to heighted vigilance of this VTE complication associated with COVID-19 infection.

RESUMEN

Coronavirus disease 2019(COVID-19) has attracted great attentions from the whole world. Traditional Chinese medicine(TCM) has been widely used and shown satisfying efficacies in treating all stages of COVID-19. In this study, the molecular interaction networks of different stages of COVID-19(the early, severe, critical and recovery stage) were constructed using the links among symptoms-related genes collected from TCMIP V2.0(http://www.tcmip.cn/), an integrated pharmacology network-computing platform for TCM. Following the network topological feature calculation and functional enrichment analysis, we found that the molecular targets and pathways related with the "immune-inflammation system" were involved throughout all the stages of COVID-19. The severe stage and the critical period of COVID-19 were occupied by a large proportion of inflammatory factors and pathways, suggesting that there might be a cytokine storm in these periods, along with respiratory disorders, cardiopulmonary dysfunction, nervous system disorders, etc. Accordingly, the therapeutic targets and pathways hit by the recommended prescriptions against COVID-19 were also aimed to regulate the balance of immune-inflammation system, nutrient absorption and metabolism, abnormal energy metabolism, the cardio-pulmonary function, nerve system function, etc., which may be related to the therapeutic effects of these prescriptions in terms of several clinical symptoms, such as expiratory dyspnea, chest tightness and shortness of breath, abdominal distension and constipation, sweating and limb cold, dizziness, and irritability, etc. The above findings reflect the integrative actions of TCM characterizing by multiple-components, multiple-targets, multiple-pathways, and multiple-effects. This study systematically constructed the molecular networks of different TCM syndromes during the development and progression of COVID-19 and uncovered the biological basis for symptomatic treatment of TCM. Furthermore, our data revealed the pharmacological mechanisms and the scientific connotation of recommended prescriptions, which may provide supports for the prevention and treatment of COVID-19 using TCM.

RESUMEN

In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province; and then named "2019 novel coronavirus (2019-nCoV)" by the World Health Organization (WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world's attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development; we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control (including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.
