Risk factors for adverse clinical outcomes with COVID-19 in China: a multicenter, retrospective, observational study
Background: The risk factors for adverse events of Coronavirus Disease-19 (COVID-19) have not been well described. We aimed to explore the predictive value of clinical, laboratory and CT imaging characteristics on admission for short-term outcomes of COVID-19 patients.Methods: This multicenter, retrospective, observation study enrolled 703 laboratory-confirmed COVID-19 patients admitted to 16 tertiary hospitals from 8 provinces in China between January 10, 2020 and March 13, 2020. Demographic, clinical, laboratory data, CT imaging findings on admission and clinical outcomes were collected and compared. The primary endpoint was in-hospital death, the secondary endpoints were composite clinical adverse outcomes including in-hospital death, admission to intensive care unit (ICU) and requiring invasive mechanical ventilation support (IMV). Multivariable Cox regression, Kaplan-Meier plots and log-rank test were used to explore risk factors related to in-hospital death and in-hospital adverse outcomes.Results: Of 703 patients, 55 (8%) developed adverse outcomes (including 33 deceased), 648 (92%) discharged without any adverse outcome. Multivariable regression analysis showed risk factors associated with in-hospital death included ≥ 2 comorbidities (hazard ratio [HR], 6.734; 95% CI; 3.239-14.003, p
Covid testing and contact tracing are the keys fro safely reopening schools during the coronavirus pandemic, new research suggests.
The British government has procured "millions" of two separate coronavirus tests that can detect not only coronavirus but several other viruses common in autumn, winter and spring, the UK's Department of Health said Monday.
Tuberculosis kills 1.5 million people each year. Lockdowns and supply-chain disruptions threaten progress against the disease as well as H.I.V. and malaria.
Questions regarding the transmissibility of the novel coronavirus disease (COVID-19) remain unanswered. It is known that the transmission of the severe acute respiratory syndrome coronavirus (SARS-CoV) occurs predominantly through droplets and contact. However, aerosols can be generated in some situations, such as orotracheal intubation, ventilation, and the use of electric or ultrasonic scalpels, and can therefore potentially contaminate the care team if adequate protection is not used. It is therefore necessary to assess issues of transmissibility of COVID-19 during surgery in infected patients. This review gathers the r...
Scientists say the UK test-and-trace scheme is not yet good enough to stop a resurgence of coronavirus.
Mayor of London Sadiq Khan has written to the PM to voice 'great surprise' at suggestions the capital could be effectively sealed off if there is a spike in coronavirus infections.
White House staff will be randomly tested for the virus. Some U.S. schools begin to reopen with fraught results.
We present the unique opportunity we had to monitor the liver, IL-6 and immune cell course before, during and after COVID-19 in a boy with autoimmune hepatitis (AIH) and type 1 diabetes (T1D). CD4+ and CD8+ T cells frequencies decreased because of prednisolone, followed by a plateauing increase whereas CD19+CD20+ B cell increased strongly and was unaffected by COVID-19 infection. Moreover, the percentage of activated CD8+ T cells expressing HLA-DR (CD8+HLA-DR+) increased during COVID-19 and subsided after its clearance. Total regulatory T cells (Tregs: CD4+CD25+CD127lowFOXP3+) remained stable. Although activated Tregs (CD4...
