Clinical characteristics of COVID-19-infected cancer patients: a retrospective case study in three hospitals within Wuhan, China

[COVID-19: Clinical, biological and radiological characteristics in adults, infants and pregnant women. An up-to-date review at the heart of the pandemic]

La propagation du nouveau coronavirus SARS-CoV-2, découvert en Chine en janvier 2020, a mené à une pandémie dès mars 2020, obligeant chaque système de soins des pays touchés à une adaptation rapide. Pour mieux faire face à cette crise sanitaire majeure, qui a donné lieu à de nombreuses publications scientifiques, nous avons synthétisé les principales études cliniques originales afin de faciliter la prise en charge au quotidien des patients atteints de COVID-19. Nous détaillons les premiers signes et l’évolution de la maladie ainsi que les différentes formes cliniques, y compris extra-pulmonaires, telles qu’elles sont connues au début de cette pandémie. Nous insistons sur les marqueurs cliniques, biologiques et scannographiques prédictifs de sévérité ou de mortalité. Enfin, nous discutons de l’impact de l’infection par le SARS-CoV-2 dans les populations suspectes d’être à haut risque de formes sévères.

Recomendaciones generales para los Servicios de Cirugía en Colombia durante la pandemia COVID-19 (SARS-CoV-2)

Este documento pretende dar algunos lineamientos útiles para la atención en los servicios quirúrgicos en Colombia durante la pandemia COVID-19, teniendo en cuenta la literatura científica publicada hasta la fecha, que ha emergido rápidamente y es probable que vaya cambiando a medida que el conocimiento sobre esta materia avance y permita generar nuevas recomendaciones acordes.  Estas medidas están sujetas a revisión periódica según la situación global y local de la pandemia así como su etapa de desarrollo cambien y deben aplicarse de acuerdo con las necesidades particulares de cada hospital, así como las recomendaciones de las autoridades competentes del Gobierno Nacional colombiano. Cada servicio de cirugía podrá implementar estas recomendaciones en función de sus circunstancias particulares.

Prevalence of Comorbidities in COVID-19 Patients: A Systematic Review and Meta-Analysis

BACKGROUND

In this study, we aimed to assess the prevalence of comorbidities in the confirmed COVID-19 patients. This might help showing which comorbidity might pose the patients at risk of more severe symptoms.

METHODS

We searched all relevant databases on April 7th, 2020 using the keywords ("novel coronavirus" OR COVID-19 OR SARS-CoV-2 OR Coronavirus) AND (comorbidities OR clinical characteristics OR epidemiologic*). We reviewed 33 papers' full text out of 1053 papers. There were 32 papers from China and 1 from Taiwan. There was no language or study level limit. Prevalence of comorbidities including hypertension, diabetes mellitus, cardiovascular disease, chronic lung disease, chronic kidney disease, malignancies, cerebrovascular diseases, chronic liver disease and smoking were extracted to measure the pooled estimates. We used OpenMeta and used random-effect model to do a single arm meta-analysis.

RESULTS

The mean age of the diagnosed patients was 51 years. The male to female ratio was 55 to 45. The most prevalent finding in the confirmed COVID-19 patients was hypertension, which was found in 1/5 of the patients (21%). Other most prevalent finding was diabetes mellitus (DM) in 11%, cerebrovascular disease in 2.4%, cardiovascular disease in 5.8%, chronic kidney disease in 3.6%, chronic liver disease in 2.9%, chronic pulmonary disease in 2.0%, malignancy in 2.7%, and smoking in 8.7% of the patients.

CONCLUSION

COVID-19 infection seems to be affecting every race, sex, age, irrespective of health status. The risk of symptomatic and severe disease might be higher due to the higher age which is usually accompanied with comorbidities. However, comorbidities do not seem to be the prerequisite for symptomatic and severe COVID-19 infection, except hypertension.

COVID-19 pandemic: Case studies and perspectives

As of September 9, 2020, Worldwide coronavirus disease 2019 (COVID-19) has caused 894 000 deaths with over 27.5 million confirmed cases. There is an urgent need for effective treatment. Considerable efforts have been placed on developing novel therapeutics, including antivirals and vaccines. Current management of COVID-19 is supportive, with several experimental drugs. Respiratory failure from acute respiratory distress syndrome overshadowed by severe cytokine storm appears to be the leading cause of mortality. This article has reviewed several unique case studies published from December 2019 through July 31, 2020 with the above perspectives.

Management of Hepatocellular Carcinoma during the COVID-19 Pandemic - São Paulo Clínicas Liver Cancer Group Multidisciplinary Consensus Statement

More than 18 million people in 188 countries have been diagnosed as having coronavirus disease (COVID-19), and COVID-19 has been responsible for more than 600,000 deaths worldwide. Brazil is now the second most affected country globally. Faced with this scenario, various public health measures and changes in the daily routines of hospitals were implemented to stop the pandemic. Patients with hepatocellular carcinoma (HCC) are at an increased risk for severe COVID-19 as they present with two major diseases: cancer and concomitant chronic liver disease. The COVID-19 pandemic can significantly impact the management of HCC patients from diagnosis to treatment strategies. These patients need special attention and assistance at this time, especially since treatment for tumors cannot be delayed in most cases. The aim of this guideline was to standardize the management of HCC patients during the COVID-19 pandemic. This document was developed, on the basis of the best evidence available, by a multidisciplinary team from Instituto do Câncer do Estado de São Paulo (ICESP), and Instituto Central of the Hospital das Clínicas da Universidade de São Paulo (HC-FMUSP), which are members of the São Paulo Clínicas Liver Cancer Group.

Association of procalcitonin levels with the progression and prognosis of hospitalized patients with COVID-19

Rationale: Coronavirus disease 2019 (COVID-19) was first announced in Wuhan, and has rapidly evolved into a pandemic. However, the risk factors associated with the severity and mortality of COVID-19 are yet to be described in detail. Methods: We retrospectively reviewed the information of 1525 cases from the Leishenshan Hospital in Wuhan. Univariate and multivariate Cox regression analyses were generated to explore the relationship between procalcitonin (PCT) level and the progression and prognosis of COVID-19. Univariate and multivariate logistic regression analyses were performed to explore the relationship between disease severity in hospitalized patients and their PCT levels. Survival curves and the cumulative hazard function for COVID-19 progression were conducted in the two groups. To further detect the relationship between the computed tomography score and survival days, curve-fitting analyses were performed. Results: Patients in the elevated PCT group had a higher incidence of severe and critical severity conditions (P < 0.001), death, and higher computed tomography (CT) scores. There was an association between elevated PCT levels and mortality in the univariate ((hazard ratio [1], 3.377; 95% confidence interval [2], 1.012-10.344; P = 0.033) and multivariate Cox regression analysis (HR, 4.933; 95% CI, 1.170-20.788; P = 0.030). Similarly, patients with elevated PCT were more likely to have critically severe disease conditions in the univariate (odds ratio [2], 7.247; 95% CI, 3.559-14.757; P < 0.001) and multivariate logistic regression analysis (OR, 10.679; 95% CI, 4.562-25.000; P < 0.001). Kaplan-Meier curves showed poorer prognosis for patients with elevated PCT (P = 0.024). The CT score 1 for patients with elevated PCT peaked at day 40 following the onset of symptoms then decreased gradually, while their total CT score was relatively stable. Conclusion: PCT level was shown as an independent risk factor of in-hospital mortality among COVID-19 patients. Compared with inpatients with normal PCT levels, inpatients with elevated PCT levels had a higher risk for overall mortality and critically severe disease. These findings may provide guidance for improving the prognosis of patients with critically severe COVID-19.
