ABSTRACT
@#Objective To explore the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and aortic dissection (AD). Methods Fifty three patients with AD diagnosed by CTA in our hospital from January 2016 to January 2018 were selected. All the patients with AD were scored by the STOP-BANG questionnaire. The patients who scored more than or equal to 3 received polysomnography (PSG) after surgical or conservative treatment, and according to whether the sleep apnea-hypopnea index was higher than or equal to 5. Fifty-three patients were divided into an OSAHS group and a non OSAHS group. Results There were 18 patients with 17 males and 1 female at average age of 43.3±8.4 years in the OSAHS group, and 35 patients with 23 males and 12 females at average age of 56.6±12.9 years in the non OSAHS group. There was no statistical difference between the two groups in the Stanford classification of aortic dissection, the time of onset, personal history, the history of diabetes, coronary heart disease and hyperlipidemia, or post-treatment systolic/diastolic blood pressure before sleep (P>0.05). The age of patients in the OSAHS group was significantly less than that in the non OSAHS group (P<0.01), the proportion of men/women (P=0.021), weight (P<0.01), height (P=0.028), body mass index (P<0.01), and post-treatment systolic/diastolic blood pressure after waking up (P=0.028,P=0.044) in the OSAHS group were significantly higher than those in the non OSAHS group. In the OSAHS group, the proportion of previous hypertension was significantly higher than that in the non OSAHS group (P=0.042). Conclusion AD patients combined with OSAHS are mostly male patients. The number of young and high-fat people is significantly more than that in the non OSAHS group. OSAHS may be one of the risk factors for young, high-fat men with AD.
ABSTRACT
OBJECTIVE: To investigate the predictive value of quick sequential organ failure assessment (qSOFA) score on the prognosis of adult patients with infection in intensive care unit (ICU). METHODS: A retrospective analysis was conducted on the clinical data of the infected patients in the ICU of the 401st Hospital of the People's Liberation Army from August 1st, 2000 to December 31st, 2017. The clinical data included patients' gender, age, basic diseases, etc.; the worst values of vital signs and laboratory test results within 24 hours of admission were recorded, the scores of the qSOFA, sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation II (APACHE II) were calculated separately; the outcome of ICU was recorded. The predictive values of three scoring systems were evaluated by receiver operating characteristic curve (ROC). RESULTS: Excluding patients with incomplete clinical data, cancer and immunosuppressive patients, a total number of 1 059 patients were enrolled in this study, with 679 males and 380 females, the average age was 72.57±16.06, the ICU mortality was 35.32% (374/1 059). The ROC curve analysis showed that the areas under ROC curve (AUC) of APACHE II, SOFA, qSOFA scores to predict the prognosis of infected patients were 0.713, 0.744 and 0.662, respectively. Although the AUC of qSOFA in predicting prognosis was significantly lower than that of other two scoring systems (both P < 0.05), but it still had some predictive ability. According to the Youden index, the best cut-off point for qSOFA was 2 to evaluate the prognosis of the infection, and the sensitivity was 71.65%, the specificity was 53.87%, the positive likelihood ratio was 1.55, the negative likelihood ratio was 0.53, the positive predictive value was 0.426, the negative predictive value was 0.799, and the accuracy was 59.62%. The mortality of the infected patients was increased with qSOFA score, and the mortality difference among patients with different qSOFA scores was statistically significant (χ2 = 84.605, P = 0.000). The patients were divided into two groups according to the cut-off value of qSOFA, and the mortality in qSOFA score ≥2 group was higher than that in qSOFA score < 2 group [odds ratio (OR) = 2.767, 95% confidence interval (95%CI) = 2.116-3.617, P = 0.000]. CONCLUSIONS: qSOFA, SOFA and APACHE II scores have the capability of predicting the outcome for the infected patients. qSOFA score is expected to be a quick and simple tool to judge the prognosis of ICU infection patients because of its advantages of quick acquisition.
