Objective To investigate the correlation between prestroke comorbidity and long-term outcomes in patients with acute cerebral infarction.Methods Consecutive acute ischemic stroke patients who were hospitalized were prospectively recruited from August 2010 to November 2012.Six hundred and forty-four patients were enrolled,the baseline data including Charlson Comorbidity Index (CCI),National Institute of Health Stroke Scale (NIHSS) score,type of Oxfordshire Community Stroke Project (OCSP:total anterior circulation infarct,partial anterior circulation infarct,posterior circulation infarct and lacunar infarct) were recorded.And recovery was assessed by modified Rankin Scale (mRS) 90 days after stroke by telephone interview (mRS score ≤ 2 reflected good prognosis,and mRS score > 2 reflected unfavorable prognosis).Because CCI included specific comorbidity,we considered CCI,CCI without specific comorbidity and specific comorbidity as variable respectively.After screening the risk factors affecting prognosis using univariate analysis,the relationship between comorbidity and prognosis was estimated using multinomial logistic regression model.Results CCI was an independent predictor of good prognosis and unfavorable prognosis (OR =3.446,95% CI 1.662-7.417; P =0.001).Congestive heart failure and diabetes were each independent predictor of good prognosis and unfavorable prognosis also (diabetes:OR =2.584,95% CI 1.709-3.906,P =0.000; congestive heart failure:OR =6.229,95% CI 1.705-22.755,P =0.006).Conclusions After acute ischemic stroke,the patients with the higher CCI score,diabetes and congestive heart failure are more likely to achieve unfavorable outcome.CCI,diabetes and congestive heart failure can each be used as a sensitive index to evaluate the 90 d prognosis of patients.Trial registration Clinical Research Center of China (CHiCTR-OCH-14004228)

Objective The scale lists applied in the diagnosis and treatment of heat stroke generally draw on other specialty scales, and there is no specific scoring system on heat stroke verified by large-scale clinical trials.The paper compared common acute physiology and chronic health evaluationⅡ( APACHEⅡ) , dissolved inorganic carbon score( DIC score) , multiple organ dysfunction score( MOD score) for the prognostic evaluation of heat stroke patients, the sum of three scores and the sum of the percentages of three scores to the score sum on prognostic evaluation of heat stroke patients in order to find a scoring method with higher clinical value. Methods APACHEⅡ, MOD score, DIC score, the sum of three scores and the sum of three scores were applied on 43 patients with heat stroke admitted in our neurological intensive care unit ( NICU) or in intensive care unit ( ICU) .The analysis of the area under the receiver operating characteristic ( ROC) curve( AUC) analysis was made among five scores. Results The weighted sum of three scores has the largest AUC ( 0.896 ) in predicting the death of HS patients according to AUC.The optimal MOD score was 5.5 in predicting the death of HS with a sensitivity of 72.7%and a specifici-ty of 99.69%.The optimal DIC score was 1.5 in predicting the death of HS with a sensitivity of 100%and a specificity of 56.2%.The op-timal score of the sum of the percentages of three scores to the score sum was 0.727 in predicting the death of HS with a sensitivity of 72.7%and a specificity of 100%. Conclusion All the five scores can predict the prognosis of patients with heat stroke.However, due to the deficiency in the prognosis value, a more specific scoring system needs to be developed.
