The patients were divided into two groups: severe acute exacerbation(SAE) group(n = 382) and non-SAE group(n = 1075). The SAE group was classified as the high-risk group based on the higher incidence of ACLF in this group than in the non-SAE group(13.6% vs 0.4%). Two-thirds of SAE patients were randomly assigned to risk-model derivation and the other one-third to model validation. Univariate risk factors associated with the outcome were entered into a multivariate logistic regression model for screening independent risk factors. Each variable was assigned an integer value based on the regression coefficients, and the final score was the sum of these values in the derivation set. Model discrimination and calibration were assessed using area under the receiver operating characteristic curve and the Hosmer-Lemeshow test. RESULTS: The risk prediction scoring model includedthe following four factors: age ≥ 40 years, total bilirubin ≥ 171 μmol/L, prothrombin activity 40%-60%, and hepatitis B virus DNA > 107 copies/m L. The sum risk score ranged from 0 to 7; 0-3 identified patients with lower risk of ACLF, whereas 4-7 identified patients with higher risk. The Kaplan-Meier analysis showed the cumulative risk for ACLF and ACLF-related death in the two risk groups(0-3 and 4-7 scores) of the primary cohort over 56 d, and log-rank test revealed a significant difference(2.0% vs 33.8% and 0.8% vs 9.4%, respectively; both P < 0.0001). In the derivation and validation data sets, the model had good discrimination(C index = 0.857, 95% confidence interval: 0.800-0.913 and C index = 0.889, 95% confidence interval: 0.820-0.957, respectively) and calibration demonstrated by the Hosmer-Lemeshow test(χ2 = 4.516, P = 0.808 and χ2 = 1.959, P = 0.923, respectively).CONCLUSION: Using the scoring model, clinicians can easily identify patients(total score ≥ 4) at high risk of ACLF and ACLF-related death early during SAE.展开更多

Thus,...Day 100 prognostic factors post-autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT) to predict clinical outcomes in diffuse large B-cell lymphoma (DLBCL) patients have not been studied. Thus, we retrospectively examined if day 100 absolute monocyte/lymphocyte prognostic score (AMLPS-100) affects clinical outcomes by landmark analysis from day 100 post-APBHSCT in DLBCL. Only DLBCL patients in complete remission at day 100 post-APBHSCT were evaluated. From 2000 to 2007, 134 consecutive DLBCL patients are qualified for the study. Patients with a day 100 absolute monocyte count (AMC-100) ≥ 630 cells/μL and day 100 absolute lymphocyte count (ALC-100) ≤ 1000 cells/μL experienced inferior overall survival (OS) and progression free survival (PFS). On multivariate analysis, the AMC-100 and ALC-100 remained independent predictors of OS and PFS. Combining both values into the AMLPS-100, the 5-year OS rates for low, intermediate, and high AMLPS-100 risk groups were 94% (95% CI, 83.0% - 98.1%), 70% (95% CI, 58.6% - 80.1%), and 13% (95% CI, 3.4% - 40.5%), respectively;and the 5-year PFS rates were 87% (95% CI, 74.0% - 94.1%), 68% (95% CI, 56.0% - 77.8%), and 13% (95% CI, 3.4% - 40.5%), respectively. The AMLPS-100 is a simple biomarker score that can stratify clinical outcomes from day 100 post-APBHSCT in DLBCL patients.展开更多

This study evaluated the prognostic potential of an immune score system to supplement the TNM staging system. Mothodsg An immunohistochemical analysis was conducted to assess the density of T cells, B cells, and myeloid-derived suppressor cells （MDSCs） in cancer tissues from 100 stage IIIA gastric cancer patients; the expression of the high-mobility group protein B1 （HMGB1） was also evaluated in cancer cells. The relationship between the overall survival （OS）, disease-free survival （DFS）, and immunological parameters was analyzed.Results： An immune score system was compiled based on the prognostic role of the density ofT cells, B cells, MDSCs, and the expression of HMGB1 in cancer tissues. The median 5-year survival of this group of patient was 32%. However, the 5-year survival rates of 80.0%, 51.7%, 0%, 5.8%, and 0% varied among the patients with an immune score of 4 to those with an immune score of 0 based on the immune score system, respectively. Similarly, differences in DFS rates were observed among the immune score subgroups. Concluslons： An immune score system could effectively identify the prognostic heterogeneity within stage IliA gastric cancer patients, implying that this immune score system may potentially supplement the TNM staging system, and help in identifying a more homogeneous group of patients who on the basis of prognosis can undergo adjuvant therapy.展开更多

In particular, whether the intermediate vaginal flora type should be included in the group to be treated for BV. This vaginal smear type is a mixture of Lactobacillus and Gardnerella or Bacteroides spp. We examined three vaginal flora types, excluding the mixed-type, with a Nugent Score of 4 and evaluated their significance in achieving term delivery. The subjects were pregnant women who were examined at our Hospital between June 2009 and December 2010. Their vaginal swabs were taken at their first prenatal visit and were studied by Gram staining. The resulting Nugent Score 4 organisms were further classified into the following four types: mixed-type, gram-positive cocci type, Bifidobacterium type, and non-bacterial type. The clinical courses for all the types except “mixed-type” were followed-up. Among the 566 pregnant women, 58 (10.2%) had a Nugent Score of 4. There were 38 cases of mixed-type (65.5%), 3 cases of gram-positive cocci type (5.2%), 10 cases of Bifidobacterium type (17.2%), and 7 cases of non-bacterial type (12.1%). The three women with the gram-positive cocci type attained successful term delivery despite two of them experiencing GBS infection and requiring treatment with penicillin and tocolytics. Among the 10 cases of Bifidobacterium type, 5 cases were term delivery with no therapy, 3 cases were term delivery with metronidazole treatment and 2 cases were preterm birth with maternal complications. Among the 7 cases of non-bacterial type, 6 cases were diagnosed with preterm PROM, and 5 of them resulted in preterm birth despite prophylactic antibiotic therapy. Classification of smears with a Nugent score of 4 into four bacterial morphotypes may be effective, for required treatment may vary depending on the morphotype.展开更多

Independent prognostic predictors of short-term HBV-ACLF mortality include the Child-Turcotte-Pugh（CTP） score, the model for end-stage liver disease（MELD） score, other MELD-based indices and the dynamic changes in these indices. The aims of this study were to evaluate the existing prognostic scores in a large cohort of HBV-ACLF patients and create a new predictive model. We retrospectively reviewed 392 HBV-ACLF patients from December 2008 to November 2011 and evaluated their 3-month survival. The predictive accuracy of CTP, MELD and MELD-based indices and the dynamic changes in the MELD-related scores（Δ scoring systems） upon admission and after two weeks of treatment were compared using the area under the receiver operating characteristic（ROC） curve method. Life-threatening factors and a series of bio-clinical parameters were studied by univariate and multivariate analyses. Among the existing scores, MELD had the best predictive ability. However, our new regression model provided an area under the curve of 0.930±0.0161（95% CI： 0.869 to 0.943）, which was significantly larger than that obtained with the MELD score at admission and after two weeks of treatment as well as with the dynamic changes of the MELD score（0.819, 0.921, and 0.826, respectively）（Z=3.542, P=0.0004）. In a large cohort of patients retrospectively reviewed for this study, our prognostic model was superior to the MELD score and is, therefore, a promising predictor of short-term survival in patients with HBV-ACLF.展开更多

文摘AIM: To establish a clinical scoring model to predict risk of acute-on-chronic liver failure(ACLF) in chronic hepatitis B(CHB) patients.METHODS: This was a retrospective study of 1457 patients hospitalized for CHB between October 2008 and October 2013 at the Beijing Ditan Hospital, Capital Medical University, China. The patients were divided into two groups: severe acute exacerbation(SAE) group(n = 382) and non-SAE group(n = 1075). The SAE group was classified as the high-risk group based on the higher incidence of ACLF in this group than in the non-SAE group(13.6% vs 0.4%). Two-thirds of SAE patients were randomly assigned to risk-model derivation and the other one-third to model validation. Univariate risk factors associated with the outcome were entered into a multivariate logistic regression model for screening independent risk factors. Each variable was assigned an integer value based on the regression coefficients, and the final score was the sum of these values in the derivation set. Model discrimination and calibration were assessed using area under the receiver operating characteristic curve and the Hosmer-Lemeshow test. RESULTS: The risk prediction scoring model includedthe following four factors: age ≥ 40 years, total bilirubin ≥ 171 μmol/L, prothrombin activity 40%-60%, and hepatitis B virus DNA > 107 copies/m L. The sum risk score ranged from 0 to 7; 0-3 identified patients with lower risk of ACLF, whereas 4-7 identified patients with higher risk. The Kaplan-Meier analysis showed the cumulative risk for ACLF and ACLF-related death in the two risk groups(0-3 and 4-7 scores) of the primary cohort over 56 d, and log-rank test revealed a significant difference(2.0% vs 33.8% and 0.8% vs 9.4%, respectively; both P < 0.0001). In the derivation and validation data sets, the model had good discrimination(C index = 0.857, 95% confidence interval: 0.800-0.913 and C index = 0.889, 95% confidence interval: 0.820-0.957, respectively) and calibration demonstrated by the Hosmer-Lemeshow test(χ2 = 4.516, P = 0.808 and χ2 = 1.959, P = 0.923, respectively).CONCLUSION: Using the scoring model, clinicians can easily identify patients(total score ≥ 4) at high risk of ACLF and ACLF-related death early during SAE.

In particular, whether the intermediate vaginal flora type should be included in the group to be treated for BV. This vaginal smear type is a mixture of Lactobacillus and Gardnerella or Bacteroides spp. We examined three vaginal flora types, excluding the mixed-type, with a Nugent Score of 4 and evaluated their significance in achieving term delivery. The subjects were pregnant women who were examined at our Hospital between June 2009 and December 2010. Their vaginal swabs were taken at their first prenatal visit and were studied by Gram staining. The resulting Nugent Score 4 organisms were further classified into the following four types: mixed-type, gram-positive cocci type, Bifidobacterium type, and non-bacterial type. The clinical courses for all the types except “mixed-type” were followed-up. Among the 566 pregnant women, 58 (10.2%) had a Nugent Score of 4. There were 38 cases of mixed-type (65.5%), 3 cases of gram-positive cocci type (5.2%), 10 cases of Bifidobacterium type (17.2%), and 7 cases of non-bacterial type (12.1%). The three women with the gram-positive cocci type attained successful term delivery despite two of them experiencing GBS infection and requiring treatment with penicillin and tocolytics. Among the 10 cases of Bifidobacterium type, 5 cases were term delivery with no therapy, 3 cases were term delivery with metronidazole treatment and 2 cases were preterm birth with maternal complications. Among the 7 cases of non-bacterial type, 6 cases were diagnosed with preterm PROM, and 5 of them resulted in preterm birth despite prophylactic antibiotic therapy. Classification of smears with a Nugent score of 4 into four bacterial morphotypes may be effective, for required treatment may vary depending on the morphotype.

文摘Patients with acute-on-chronic hepatitis B liver failure（HBV-ACLF） show high morbidity and mortality. Independent prognostic predictors of short-term HBV-ACLF mortality include the Child-Turcotte-Pugh（CTP） score, the model for end-stage liver disease（MELD） score, other MELD-based indices and the dynamic changes in these indices. The aims of this study were to evaluate the existing prognostic scores in a large cohort of HBV-ACLF patients and create a new predictive model. We retrospectively reviewed 392 HBV-ACLF patients from December 2008 to November 2011 and evaluated their 3-month survival. The predictive accuracy of CTP, MELD and MELD-based indices and the dynamic changes in the MELD-related scores（Δ scoring systems） upon admission and after two weeks of treatment were compared using the area under the receiver operating characteristic（ROC） curve method. Life-threatening factors and a series of bio-clinical parameters were studied by univariate and multivariate analyses. Among the existing scores, MELD had the best predictive ability. However, our new regression model provided an area under the curve of 0.930±0.0161（95% CI： 0.869 to 0.943）, which was significantly larger than that obtained with the MELD score at admission and after two weeks of treatment as well as with the dynamic changes of the MELD score（0.819, 0.921, and 0.826, respectively）（Z=3.542, P=0.0004）. In a large cohort of patients retrospectively reviewed for this study, our prognostic model was superior to the MELD score and is, therefore, a promising predictor of short-term survival in patients with HBV-ACLF.
