Objective To investigate the outcome and prognostic factors of hospital mortality in patients with acute cerebrovascular disease requiring mechanical ventilation.Methods Data from 94 patients with acute cerebrovascular disease in central intensive care unit(ICU) were collected and retrospectively analyzed.Prognostic factors of hospital mortality were analyzed by univariate statistics and multivariate logistic regression.Results Hospital mortality was 53.2%(50/94).There was significance diference in parameters such as APACHE II score，blood glucose，lengh of hospital stay，lengh of ICU stay，time of mechanical ventilation，incision of trachea，lung infections，lesion loci and its naturer between the survival and non-survival groups（all Plt;0.05）.Multivariate logistic regression revealed that blood glucose，lung infections，diseased region under tentorium of cerebellum，time of mechanical ventilation were independent prognostic risk factors of hospital mortality(all Plt;0.05).Whereas the lengh of ICU stay was protective factor(Plt;0.05).Conclusion The hospital mortality is considerably high in patients with acute cerebrovascular disease requiring mechanical ventilation. The prognostic factors such as blood glucose and lung infections should be evaluate cautiously and prevented aggressively.
Objectives To investigate the correlation between blood total cholesterol (TC) and prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL) and to provide references for clinical treatment and prognosis assessment. Methods We included 232 ISSNHL patients with total deafness in Wenzhou Central Hospital from June 2015 to March 2017 using a prospective cohort design. Recording information including age, gender, hypertension, diabetes mellitus, vertigo, level of blood total cholesterol (TC), level of triglyceride (TG), level of low-density lipoprotein (LDL-C) and LDL/HDL ratio (LDL-C/HDL-C) were collected. Correlation between the prognosis of ISSNHL and blood total cholesterol were analyzed by univariable and multivariable logistic regression analysis. Results The clinical effective rate of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L was higher than that of patients with TC lower than 5.2 mmol/L (univariable: RR=6.49, 95%CI 3.16 to 13.30, P<0.001; multivariable-adjusted covariates: RR=6.15, 95%CI 2.66 to 14.3,P<0.001) with significant difference. No significant difference was found between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (univariable: RR=1.02, 95%CI 0.52 to 2.00,P=0.960; multivariable-adjusted covariates: RR=1.61, 95%CI 0.55 to 4.73, P=0.386). Gender-specific analysis showed for both male and female groups, the effective rates of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L were significantly higher than those of patients with TC lower than 5.2 mmol/L. There was no significant difference between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (P>0.05) in either male group or female group. Conclusion The current study suggests that patients with levels of TC ranging from 5.2 mmol/L to 6.2 mmol/L predicts the best prognosis.
Objective To study the mortality and prognostic factors of post-operative acute respiratory failure in cancer patients. Methods There were 1632 postoperative cancer patients from2004 to 2006 in the ICU of Cancer Hospital, in which 447 patients were complicated with acute respiratory failure ( intubation or tracheotomy and mechanical ventilation) . The clinical data was retrospectively analyzed. Stepwise logistic regression analysis was used to identify variables associated with mortality for acute respiratory failure. Results In 447 patients with acute respiratory failure ( male 260, female 187) , 106 cases died with a mortality of 6. 5% . Single factor analysis showed that acute morbodities ( shock, infection, organ failure) , intervention ( continuous renal replacement therapy, vasopressor drugs) , the 28-day ICU free days and APACHE scores ( ≥ 20) had significant differences between the survivor and non-survivor. Multiple logistic regression analysis showed that duration of operation( P = 0. 008, OR 1. 032, 95% CI 1. 008-1. 057) , APACHEⅡ≥20 scores( P =0. 000, OR12. 200, 95% CI 2. 896-51. 406) , organ function failure( P =0. 000, OR 13. 344,95% CI 3. 791-7. 395) were associated with mortality of acute respiratory failure. Conclusion Duration of operation, organ function failure, and APACHE Ⅱ scores were risk prognostic factors for postoperative cancer patients with acute respiratory failure.
Objective To evaluate the influence of resection status, pathological type, pathological stage and postoperative adjuvant therapy on prognosis of surgically treated thymic carcinoma. Methods In this retrospective study, 56 patients with surgically treated thymic carcinoma in the Department of Thoracic Surgery, Peking Union Medical College Hospital from January 2005 to December 2015 were enrolled. There were 30 males and 26 females aged 52.1±11.5 years ranging from 22 to 81 years. The survival curve was performed by Kaplan-Meier method. The prognostic factors affecting overall survival (OS) and disease-free survival (DFS) were analyzed by one-way analysis of variance (ANOVA). Results R0 resection was performed in 37 patients (67.9%), and other resections in 19 (32.1%); 13 patients suffered thymic carcinoma with Masaoka stage Ⅰ-Ⅱ, 26 Ⅲ, and 17 Ⅳ. Low-grade thymic carcinoma was found in 42 patients, and high-grade in 14. Postoperative radiotherapy, chemotherapy and chemoradiotherapy were performed on 17, 12 and 18 patients respectively and 9 patients were untreated. Forty-one patients was followed up for 1 to 10 years, and the follow-up rate was 73%. The 1-, 3- and 5-year OS rates were 93%, 74% and 61%, respectively. Resection status and pathological stage affected OS. Postoperative radiotherapy after R0 resection affected DFS, but did not affect OS. Conclusion Most patients with thymic carcinoma after surgery can survive for a long period, and R0 resection is the most important prognostic factor of thymic carcinoma. Postoperative radiotherapy after R0 resection in patients with Masaoka stage Ⅱ-Ⅲ is recommended.
Objective To investigate the clinical features of non-small cell lung cancer (NSCLC) patients with long-term survival and the related factors for treatment. Methods A retrospective analysis of clinical features, treatment factors, and survival was performed for 963 patients with pathologically confirmed stage Ⅳ NSCLC between January 2010 and December 2015 from Department of Thoracic Oncology, West China Hospital, Sichuan University. Results The median overall survival (OS) of the 963 patients was 20.8 months, and the 1-, 3-, 5-, and 7-year survival rates were 72.0%, 21.4%, 15.2%, and 4.8%, respectively. There were 81 patients in the long-term survival group (OS>60 months) and 882 in the non-long-term survival group (OS<60 months). Previous surgery, thoracic radiotherapy and epidermal growth factor receptor (EGFR) gene positive significantly increased the 5-year actual survival rate, reducing the risk of death by 62.0%, 58.8%, and 58.1%, respectively. Compared with the non-long-term survival group, more patients in the long-term survival group received two or more means of treatment including surgery, thoracic radiotherapy, and targeted therapy (28.4% vs. 11.6%, P<0.001) and more patients benefited from fourth- or further-line treatment (24.7%vs. 11.1%, P<0.001). Cox multivariate regression analysis indicated that performance status [hazard ratio (HR)=1.388, 95% confidence interval (CI) (1.199, 1.608), P<0.001] , N stage [HR=1.160, 95%CI (1.058, 1.272), P=0.002] , EGFR gene status [HR=0.588, 95%CI (0.469, 0.738), P<0.001] , previous surgery [HR=0.626, 95%CI (0.471, 0.832), P=0.001] , and thoracic radiotherapy [HR=0.592, 95%CI (0.480, 0.730), P<0.001] were independent prognostic factors of OS. Conclusions Good performance status, early N staging, EGFR mutation, previous surgery, and thoracic radiotherapy are important prognostic factors affecting the survival of advanced NSCLC patients. Long-term survival benefits from combined treatment and effective further-line therapies.
Immune-mediated necrotizing myopathy (IMNM) is a rare type of autoimmune inflammatory myopathy, which can be divided into anti-signal recognition particle antibody positive IMNM, anti-3-hydroxy-3-methylglutaryl coenzyme A reductase antibody positive IMNM and serum antibody negative IMNM according to different autoantibodies. The prognosis of IMNM is worse than that of most other types of myositis. At present, there are differences in the studies of prognostic factors of IMNM at home and abroad, and there is a lack of large-scale clinical studies. This article will review the prognostic factors of IMNM.
ObjectiveTo analyze perioperative prognostic factors of pediatric patients undergoing surgical correction of ventricular septal defect (VSD)and severe pulmonary arterial hypertension (PAH). MethodsForty pediatric patients with VSD and severe PAH (mean pulmonary artery pressure (PAPm) < 50 mm Hg)who underwent surgical repair in Beijing Anzhen Hospital from 2004 to 2012 were included in the study. There were 21 male and 19 female patients with their age of 7.2±3.3 years and body weight of 19.6±7.1 kg. All the patients were randomly divided into 2 groups:Group Ⅰ (Group=0, n=20, M/F:12/8, continuous nitroglycerin administration via central venous catheter (CVC)and GroupⅡ (Group=1, n=20, M/F:9/11, continuous prostaglandin E1 (PGE1)administration via CVC). The duration of intubation (Tintubation)was used as the dependent variable (Y). Patient age, cardiopulmonary bypass time (TCPB), postoperative PAPm, pulmonary vascular resistance index (PVRI), systemic to pulmonary pressure ratio (Ps/p), Group, left ventricular stroke work index (LVSWI)and right ventricular stroke work index (RVSWI)were used as independent variables (X). Multivariate liner regression analysis model was used to evaluate the influence of X on Y. ResultsThere was no perioperative death or severe complication in this group. Perioperative prognostic factors of pediatric patients undergoing surgical correction of VSD and severe PAH included group[x1, P=0.004, 95% CI (-71, -16)], TCPB[x2, P=0.011, 95% CI (0.9, 5.8)], posto-perative PAPm (x3, P=0.004 with 95% CI 3.2 to 13.3), RVSWI (x4, P=0.003 with 95% CI-16.9 to-4.3)and PVRI (x5, P=0.03 with 95% CI-0.29 to-0.02). The standardized regression equation was:Y=-0.60x1+0.54x2+2.22x3-1.70x4-0.15x5. ConclusionPGE1 administration, TCPB, postoperative PAPm, RVSWI and PVRI are predominant perioperative prognostic factors of pediatric patients undergoing surgical correction of VSD and severe PAH.
【Abstract】ObjectiveTo analyze the factors influencing the prognosis of patients with bile duct carcinoma after resection. MethodsThe clinical data of 120 patients with bile duct carcinoma receiving resection in our hospital from 1980 to 2004 were collected retrospectively and clinicopathologic factors that might influence survival were analysed. A multiple factor analysis was performed through Cox proportional hazard model. ResultsThe overall 1year, 3year and 5year survival rates were 71.7%, 32.5% and 19.2% respectively. The single factor analysis showed that the major significant factors influencing survival of these patients were histological type of the lesions, lymph node metastasis, pancreatic infiltration, duodenal infiltration, resected surgical margin, perineural infiltration, peripheral vascular infiltration and depth of tumor infiltration (P＜0.05). Lymph node metastasis, pancreatic infiltration and perineural infiltration were found to be the the statistically significant factors influencing survival by multiple factor analysis through the Cox model. ConclusionThe most important prognostic factors for bile duct carcinoma after resection were lymph node metastasis, pancreatic infiltration and perineural infiltration.

Objective To establish a prediction model for the 1-, 3-, and 5-year survival rates in patients with gastric cancer liver metastases (GCLM) by analyzing prognostic factors based on the Surveillance, Epidemiology, and End Results (SEER) database. Methods Clinical and pathological data from 591 patients diagnosed with GCLM between 2010 and 2015 were obtained from the SEER database. The population was randomly divided into a training cohort and an internal validation cohort at a 7 to 3 ratio. Independent predictors of GCLM were analyzed using univariate and multifactorial Cox regression. Consequently, nomograms were constructed. The model's accuracy was verified by calibration curve, ROC curve, and the C-index, and the clinical utility of the model was analyzed through decision curve analysis. Results Tumor differentiation grade, surgical status, and chemotherapy were significantly associated with the prognosis of GCLM patients, and these three factors were included in constructing the prognostic model and plotting the nomogram. The C-index was 0.706 (95%CI 0.677 to 0.735) and 0.749 (95%CI 0.710 to 0.788) for the training set and the internal validation cohort, respectively. The results of the ROC curve analysis indicated that the area under the curve (AUC) was over 0.7 at 1, 3, and 5 years for both the training and validation cohorts. Conclusion The prediction model of the GCLM is developed based on the 3 factors, i.e., tumor differentiation grade, surgery, and chemotherapy, and shows good prediction accuracy and thus may promote clinical decision making and individualized treatment of GCLM patients.
