Methods Epidemiological data were collected among the confirmed SARS patients officially reported by Beijing Centers for Disease Control and Prevention （BCDC）, and information was also supplemented by a follow-up case survey, Chi-square test and multivariate stepwise logistic regression analysis were performed. Results Old age （over 60 years） was found to be significantly associated with SARS-related deaths in the univariate analysis. Also, history of contacting SARS patients within 2 weeks prior to the onset of illness, health occupation, and inferior hospital ranking as well as longer interval of clinic consulting （longer than 1 day） were the risk factors for SARS-related deaths. Multivariate stepwise logistic regression analysis found four risk factors for SARS-related deaths. Conclusion Old age （over 60 years） is the major risk factor for SARS-related deaths. Moreover, hospital health workers, the designated hospitals for SARS clinical services and the interval of consulting doctors （less than 1 day） are protective factors for surviving from SARS.展开更多

This study aimed to determine the risk factors for ICH and mortality in such patients.Methods: We analyzed the clinical data of 77 patients who received VV-ECMO due to severe respiratory failure from July 2013 to May 2019 at China-Japan Friendship Hospital. Demographical data, laboratory indices, imaging characteristics, and other clinical information were collected. Multivariable logistic regression analyses were performed to identify risk factors for ICH and mortality.Results: Of 77 patients, 11 (14.3%) suffered from ICH, and 36 (46.8%) survived. The survival rate was significantly lower (18.2% [2/11]vs. 51.5% [34/66],P = 0.040) in patients with ICH than in those without ICH. Multivariable analysis revealed that factors independently associated with ICH were diabetes mellitus (adjusted odds ratio [aOR]: 12.848, 95% confidence interval [CI]: 1.129-146.188,P = 0.040) and minimum fibrinogen during ECMO (aOR: 2.557, 95% CI: 1.244-5.252,P = 0.011). Multivariable analysis showed that factors independently associated with mortality were acute hepatic failure during ECMO (aOR: 9.205, 95% CI: 1.375-61.604,P = 0.022), CO2 retention before ECMO (aOR: 7.602, 95% CI: 1.514-38.188,P = 0.014), and minimum platelet concentration during ECMO (aOR: 0.130, 95% CI: 0.029-0.577,P = 0.007).Conclusions: Diabetes mellitus and minimum fibrinogen concentration during ECMO are risk factors for ICH in patients with severe respiratory failure managed using VV-ECMO. This indicated that anticoagulants use and nervous system monitoring should be performed more carefully in patients with diabetes when treated with VV-ECMO due to severe respiratory failure.展开更多
