Objective To establish a short-term mortality risk scoring standard for sepsis-associated acute respiratory distress syndrome (sARDS) and provide a reference tool for clinicians to evaluate the severity of sARDS patients. Methods A retrospective cohort study was conducted on sARDS patients admitted to the adult intensive care unit (ICU) of the First Affiliated Hospital, Hengyang Medical School, University of South China from January 1, 2013 to August 31, 2020. They were divided into a death group and a survival group according to whether they died within 28 days after admission to ICU. Clinical data of the patients was collected within 24 hours admitted to ICU. Related risk factors for mortality within 28 days after admission to ICU were screened out through univariate logistic regression analysis. A risk prediction model for mortality within 28 days after admission to ICU was established by multivariate logistic regression analysis. The Hosmer-Lemeshow χ2 test and the area under the receiver operating characteristic (ROC) curve were used to evaluate the model’s goodness-fit and accuracy in predicting 28-day mortality of the sARDS patients, respectively. Finally, the clinical prognosis scoring criteria 28-day mortality of the sARDS patients were established according to the weight coefficients of each independent risk factor in the model. Results A total of 150 patients were recruited in this study. There were 67 patients in the survival group and 83 patients in the death group with a 28-day mortality rate of 55.3%. Four independent risk factors for 28-day mortality of the sARDS patients, including invasive mechanical ventilation, the number of dysfunctional organs≥3, serum lactic acid≥4.3 mmol/L and the severity of ARDS. A risk prediction model for mortality within 28 days of the sARDS patients was established. The area under the ROC curve and 95% confidence interval (CI), sensitivity and specificity of the risk prediction model for 28-day mortality for the sARDS patients were 0.896 (95%CI 0.846 - 0.945), 80.7% and 82.1%, respectively, while that for acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score were 0.865 (95%CI 0.805 - 0.925), 71.1% and 89.6%; for sequential organ failure assessment (SOFA) score were 0.841 (95%CI 0.7799 - 0.904), 68.7%, and 82.1%; for the prediction scores of lung injury were 0.855 (95%CI 0.789 - 0.921), 81.9% and 82.1%, respectively. It was indicated that the prediction accuracy of this risk prediction model of 28-day mortality maybe was better than that of APACHE-Ⅱ score, SOFA score and prediction score of lung injury. In addition, four risk factors were assigned as invasive mechanical ventilation (12 points), serum lactic acid≥4.3mmol /L (1 point), number of organs involved≥3 (3 points), and severity of ARDS (mild for 13 points, moderate for 26 points, severe for 39 points). Further more, the score of each patient was 13 - 55 points according to the scoring criteria, and the score grade was made according to the percentile method: 13 - 23 points for the low-risk group for 28-day mortality, 24 - 34 points for the medium-risk group for 28-day mortality, 35 - 45 points for the high-risk group for 28-day mortality, and over 45 points for the extremely high-risk group for 28-day mortality. According to the scoring criteria, the prognosis of the patients in this study was analyzed. The mortality probability of each group was 0.0% in the low-risk group, 13.8% in the medium-risk group, 51.9% in the high-risk group, and 89.7% in the extremely high-risk group, respectively. Conclusions The invasive mechanical ventilation, the number of involved organs≥3, serum lactic acid≥4.3 mmol /L and the severity of sARDS are independent risk factors for 28-day mortality of the sARDS patients. The scoring criteria may predict the risk of 28-day mortality for the sARDS patients.
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 explore the distribution characteristics and prognostic risk factors of critically ill patients who has long-term hospitalization in intensive care unit ( ICU) . Methods A retrospective study was carried out to evaluate 119 critically ill patients from January 2003 to July 2009 by extracting data from computerized hospital information system. The patients were divided into a survival group and a non-survival group based on discharging outcomes. A binary logistic regression analysis wasintroduced to investigate potential risk factors of prognosis. Results Age, type of payment, entity of disease,and length of ICU stay were significantly different between the two groups ( P lt; 0. 05) in independent-Samples T test. Logistic regressions indicated that age, length of ICU stay and plasma infusion were independent predictors for worse outcome. Conclusions Age, length of ICU stay and plasma infusion may directly influence the prognosis of patients with prolonged stay in ICU. Intensive therapies should be emphasized for those patients at high risk.
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.

Macular edema (ME) secondary to central retinal vein occlusion（CRVO) often cause severe visual impairment. Intravitreal anti-vascular endothelial growth factor agents and steroids can effectively eliminate ME and improve visual function, but the visual outcome is affected by multiple factors. Retinal blood flow, especially the macular microcirculation, has significant correlation with visual outcome. Ischemic CRVO, especially patients with severe damage in the deep and superficial vascular layer of the macular zone, usually have poor visual outcome. In addition, the integrity of the multi-layer retinal structure closely correlates with the visual outcome. Patients with intact ellipsoid zone, external limit membrane beneath the fovea have good visual recovery. Additionally, good baseline visual acuity, positive response to treatment in early phase, young age and timely treatment usually brings about better visual outcome.
Objective To investigate the prognostic factors related to long-term survival after gastrectomy. Methods A total of 351 patients with gastric cancer who underwent gastrectomy were successfully followed-up in our hospital had been selected from January 2004 to December 2009. The clinicopathological and follow-up data were studied by univariate and multivariate analysis. Results The age, location of tumors, T stage, N stage, TNM stage, and differentiation were related with postoperative survival of patients with gastric cancer by using univariate analysis（P＜0.05）. By using multivariate analysis, location of tumors, T stage, N stage, and chemotherapy were independent prognostic factors（P＜0.05）. Conclusions Location of tumors, depth of tumor invation, lymph node metastasis, and chem-otherapy were independent prognostic factors for gastric cancer patients who underwent gastrectomy. Chemotherapy after surgery could increase the survival rate of gastric cancer patients with lymph node metastasis or in TNM stage Ⅲ.
ObjectiveTo explore the predictors of seizures during pregnancy, and to explore whether seizure control in the 6 months and 1 year prior to pregnancy can predict the risk of seizures during pregnancy and the occurrence of adverse maternal and infant outcomes, so as to guide the choice of the best fertility timing for women with epilepsy (WWE).MethodsA total of 46 WWE with 48 pregnancies were enrolled in Epilepsy Clinics of Tianjin Medical University from August 2016 to January 2020. Retrospective analysis was used to analyze the risk factors of epileptic seizures in pregnancy. The patients were grouped according to the time of absence of seizures during pregnancy. To analyze the influence of epileptic seizure, pregnancy complications and pregnancy outcome.Results Among 48 pregnancies, the risk of premature rupture of membranes was significantly higher in patients with epilepsy than those without epilepsy (34.6% vs. 0.0%), and the difference was statistically significant (P<0.01). There was no significant difference in the risk of PIH, GDM, gestational anemia and pregnancy complications (P>0.05). For women who had seizure during pregnancy, the mean birth weight of the offspring was slightly lower, and the incidence of low birth weight and fetal distress was higher, but the difference was not statistically significant (P>0.05); Seizures in the 6 months before pregnancy were significantly associated with seizures during pregnancy [RR=4.28, 95%CI (2.10, 8.74), P<0.01]. Further, the risk of adverse pregnancy outcomes increased significantly [RR=2.00, 95%CI (1.10, 3.65), P<0.05] for WWE who had seizure in 6 month before pregnancy; The rates of seizures during pregnancy in the two groups were 25.0% and 20.0%, but the difference was not statistically significant (P>0.05). Compared with the 6-months, the ≥1 year group had a lower risk of PIH and gestational anemia, and the offspring had a lower risk of low birth weight, premature delivery and fetal distress, but the difference was not statistically significant (P>0.05).ConclusionEnsuring seizure-free at least 6 months before pregnancy will significantly reduce the probability of seizures during pregnancy, and is significantly associated with a lower incidence of adverse pregnancy outcomes. Women of childbearing age with epilepsy are advised to plan pregnancy after reaching seizure-free at least 6 months.
ObjectiveTo summarize the current status and progress of MR imaging in field of rectal cancer.MethodsThe recent literatures on this topic were reviewed and analyzed, then the key information they provide was integrated.ResultsBesides its measurement of tumor height and length, the MR imaging was also significant in the preoperative assessments of tumor staging and prognostic factors such as the extramural vascular invasion (EMVI), circumferential resection margin (CRM), and perineural invasion (PNI). However, some drawbacks couldn’t be neglected. For instance, the conventional MR imaging was of limited use in discriminating T1, T2 and borderline T3 rectal cancer. The similar limitation applies to situation between T3 and T4a rectal cancer as well. And its performances in the N staging prior to and post-neoadjuvant chemoradiation therapy were just average. Currently the functional MR imaging like the diffusion weighted imaging (DWI), some relatively novel modalities such as the dynamic contrast enhanced MRI and chemical shift have served in the radiological diagnosis of the rectal cancer.ConclusionsMR imaging is the most frequently used modality in preoperative assessment of rectal cancer. It can describe size and location of tumor, assist in tumor staging, and evaluate prognostic factors. And it is supposed to provide critical information on decision making and prognosis judging. Besides current value of conventional MR imaging in the field of rectal cancer, some innovative techniques have shown moderate potentials as well. Due to their promising future use, detection of new biomarkers regarding rectal cancer can be expected.
