The clinical data of cases was collected, and the clinical characteristics, the microbiology data and outcomes in patients with mixed Candida/bacterial BSIs confirmed by blood culture were compared with those with candidaemia. A Logistic regression analysis was performed to investigate the independent risk factors. \u0000 \u0000 \u0000Results \u0000A total of 136 candidaemia cases were analyzed including 40 cases (29.4%) of mixed Candida/bacterial BSIs and 96 cases of candidaemia. Among the 136 candidas strains, the proportion of non-albicans exceeded the albicans (50.7% vs 49.3%), although the later was still the predominant one. There was no significant difference in the distribution of candidas strains between patients with mixed Candida/bacterial BSIs and patients with candidaemia. In patients with mixed Candida/bacterial BSIs, 25 strains (61.0%) of gram-positive cocci and 16 strains (39.0%) of gram-negative bacilli were isolated. Compared with patients with candidaemia, patients with mixed Candida/bacterial BSIs needed longer period of antifungal therapy [12.0 (4.0-25.0)days vs 7.0 (3.0-13.5) days, P=0.027], but the crude 30-day and 90-day mortality did not differ between the two groups (40.0% vs 32.3%; 45.0% vs 36.5%; both P>0.05). Univariate analysis revealed that the prior hospital stay, ICU admission at the onset of candidaemia, blood transfusion, human albumin infusion, mechanical ventilation, linezolid use and high SOFA score were related with the occurrence of mixed Candida/bacterial BSIs (all P<0.05). Multivariate analysis showed that only high SOFA score was the independent risk factor (P=0.003). \u0000 \u0000 \u0000Conclusions \u0000Gram-positive cocci were the predominant species in mixed Candida/bacterial BSIs. Compared with candidaemia, mixed Candida/bacterial BSIs needs a longer ICU stay, a longer hospital stay, and a prolonged antifungal therapy. High SOFA score is the independent risk factor for mixed Candida/bacterial BSIs. \u0000 \u0000 \u0000Key words: \u0000Candidaemia; Bacterial bloodstream; Mixed infection; Clinical characteristics; Strains distribution; Antifungal susceptibility; Risk factors; Clinical outcome","PeriodicalId":9981,"journal":{"name":"中华急诊医学杂志","volume":"28 1","pages":"748-754"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47998712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients diagnosed with AAD by CT angiography, aortography or magnetic resonance imaging within 14 days of onset were included. Patients with infectious diseases, haematological diseases, malignancies, autoimmune diseases and patients without clearly clinical diagnosis or incomplete data were excluded. The patients were initially divided into two groups based on their history of hypertension, and their clinical characteristics were compared and analyzed. We further divided AAD patients into survival group and death group according to their in-patient outcomes, and factors related to their prognoses were analyzed. Logistic regression analysis was applied to analyze the independent risk factors related to hospital death in AAD patients with P<0.05 as the significant value. \u0000 \u0000 \u0000Results \u0000The hypertensive group contained 237/346 cases included (68.45%), patients in this group were generally older than their non-hypertensive counterparts, accompanied by increased prevalence of comorbidities (coronary heart diseases or diabetes) and a statistical significant elevated admission blood pressures (systolic and diastolic, P 0.05). Hypertensive patients were less likely to receive surgical treatment compared with those without hypertension(P 0.05). Further logistic regression analysis revealed the presence of hypertension did not independently predict in-hospital mortality of AAD patients. Factors such as age, Stanford classification of the AAD, NLR and platelet counts were found to have independent predictive values for in-hospital mortality (P<0.05). \u0000 \u0000 \u0000Conclusion \u0000AAD patients with hypertension are generally older, have more comorbidities such as coronary heart diseases and diabetes. The presence of hypertension itself is not directly associated with in-hospital mortality in AAD patients, while the Stanford classification, age, NLR and platelet counts are independent risk predictors. \u0000 \u0000 \u0000Key words: \u0000Hypertension; Acute aortic dissection; Prognosis; Neutrophil to Lymphocyte ratio; Platelet counts","PeriodicalId":9981,"journal":{"name":"中华急诊医学杂志","volume":"28 1","pages":"614-618"},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43069449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were randomly divided into the control group and the experimental group, 60 cases in each group. Besides of medical treatment, the control group received routine enteral nutrition, while the experimental group received immune-enhanced nutrition for 8 days. The main parameters related to nutritional status, immune function, blood glucose, infection control of patients were collected. \u0000 \u0000 \u0000Results \u0000No significance of parameters listed above were observed between patients in the two groups at baseline. After intervention, the levels of prealbumin and lymphocyte counts in the experimental group were higher than those in the control group [(162.5±29.7) mg/L and (136.6±15.1) mg/L, (1.86±0.9) ×109/L and (1.45±0.710) ×109/L, P=0.021 and P=0.012].
