    On 16 February 1845 the Reverend W. H. Browne, rector of St John's Church in Launceston, Van Diemen's Land, wrote in his journal, "My dear Wife died very suddenly almost immediately after and in consequence of taking a preparation of Hyd. Cyan. Acid prepared & supplied by Dr Pugh". This journal entry raises a number of questions. Was Dr Pugh treating a condition which he thought merited that treatment or was it a ghastly mistake? Was Caroline Browne suffering from pulmonary tuberculosis? Was hydrocyanic acid an accepted treatment at that time? Did Mrs Browne take the wrong dose? Was an incorrect concentration of the drug prepared by Dr Pugh? Did he use the wrong pharmacopoeia in preparing the hydrocyanic acid? Why was there no inquest? Only some of these questions can be answered.

    The frequency with which patients in Child-Pugh B having hepatocellular carcinoma are treated following the international guidelines according to the Barcelona Clinic Liver Cancer stages is unknown. To investigate treatment allocation for Child-Pugh B patients in different tumour stages, with particular interest in the intermediate stage. Patients were retrospectively identified from a consecutively collected series. Treatment was carried out primarily according to the guidelines. Of 86 Child-Pugh B patients, 45 were Barcelona early stage, of which the Child-Pugh scores were 46.7% B7, 33.3% B8, 20.0% B9; 27 patients were intermediate stage (B7 59.3%, B8 37.0% and B9 3.7% respectively), 12 were advanced (41.7% B7, 25.0% B8 and 33.3% B9) and 2 were terminal (both B9). In the intermediate stage, transarterial chemoembolization (or ablation) was performed in 68.8% of the Child-Pugh B7 patients, 50% of the B8 patients and 0% of the B9 patients. Median survival of the intermediate patients was 8.0 months (9.0 in B7 vs. 6.0 in -B8/B9, P=0.048). Survival of the intermediate stage patients undergoing chemoembolisation was 22.0 months in Child-Pugh B7 and 6.0 in B8. Approximately half of the intermediate stage patients can undergo locoregional treatment with good survival when in the Child-Pugh B7. The Child-Pugh numeric score impacts survival, suggesting that this tumour stage be refined. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    Portal Hypertensive Gastropathy (PHG) occurs as a complication of cirrhotic or non-cirrhotic portal hypertension. The association between the severity of portal hypertensive gastropathy and the hepatic function, as assessed by the Child-Pugh score in patients with liver cirrhosis are poorly defined. We evaluated association between PHG and Child-Pugh score in patients with liver cirrhosis. Adults liver cirrhosis patients admitted at Adam Malik Hospital Medan during January 2016-December 2016, were included in this study. Endoscopic PHG grade, Child-Pugh score were assessed. A total of 49 patients were enrolled. Majority of cases of liver cirrhosis are due to chronic viral hepatitis B infections (65.3 %). Portal hypertensive gastropathy were observed in 46 cases; twenty-five patients (51%) showed severe portal hypertensive gastropathy. The overall prevalence of PHG and the proportion of patients with severe PHG differ about the Child-Pugh classification. PHG was present in 66.7 % of patients from Child-Pugh class A, 96 % of patients with class B, and 95.2 % of those from class C, and severe forms were present in 0 %, 36 %, and 76.2 %, respectively (P< 0.000). In conclusions, the present data suggest that the severity of portal hypertensive gastropathy is related to Child-Pugh score.

    Indocyanine green clearance, measured by percentage disappearance rate, detects alterations in liver function and may be used as a non-invasive determinant of hepatic reserve. The aims of this study were to compare liver histology and Child's-Pugh score with percentage disappearance rate and determine which variables correlated with PDR. Child's-Pugh score, liver function tests, liver biopsies and indocyanine green testing (0.5mg/kg) were performed in 102 consecutive patients with cirrhosis of diverse etiologies. Indocyanine green concentration was determined using spectrophotometric analysis (806nm) and plotted logarithmically with Michaelis-Menten kinetics to calculate the percentage disappearance rate. Liver biopsies were graded using the modified Knodell score to obtain a histological activity index. In bivariable analysis, percentage disappearance rate significantly correlated with Child's-Pugh score, albumin, bilirubin, prothrombin time and histological activity index. Albumin, prothrombin time and histological activity index were independent predictors of percentage disappearance rate in the final model (albumin ptime ptime and histological activity index.

    Full Text Available Abstract Background As anorexia and hypermetabolism are common in cirrhosis, leptin levels may be increased in this disease. In this study, we investigated the relation between the severity of disease and serum leptin levels in post-hepatitis cirrhosis and the role of body composition, gender and viral aetiology of cirrhosis in this association. Methods Thirty-five cases with post-hepatitis cirrhosis and 15 healthy controls were enrolled in this study. Body composition including body mass index, body fat percentage and body fat mass were determined. Serum leptin levels were assayed. Results Leptin levels were significantly higher among cirrhotic patients independent of sex compared to controls (p = 0.001. Female patients in both groups have had higher leptin levels than males (in cirrhotics p = 0.029, in controls p = 0.02. Cirrhotic patients in each of A, B and C subgroups according to the Child- Pugh classification revealed significantly different levels compared to controls (p = 0.046, p = 0.004, p = 0.0001, respectively. Male cirrhotics in Child-Pugh Class B and C subgroups had significantly higher leptin levels compared to male controls (p = 0.006, p = 0.008. On the other hand, female patients only in Child Pugh class C subgroup have had higher levels of serum leptin compared to controls (p = 0.022. Child-Pugh classification has been found to be the sole discriminator in determination of leptin levels in cirrhotics by linear regression (beta: 0.435 p = 0.015. Conclusion Serum leptin levels increase in advanced liver disease independently of gender, body composition in posthepatitic cirrhosis. The increase is more abundant among patients that belong to C subgroup according to the Child- Pugh classification.

    To evaluate the safety and clinical outcomes of chemoembolization in Child-Pugh class C patients with hepatocellular carcinomas (HCC). The study comprised 55 patients with HCC who were classified as Child-Pugh class C and who underwent initial chemoembolization between January 2003 and December 2012. Selective chemoembolization was performed in all technically feasible cases to minimize procedure-related complications. All adverse events within 30 days were recorded using the Common Terminology Criteria for Adverse Events (CTCAE). The tumor response to chemoembolization was evaluated using the modified Response Evaluation Criteria In Solid Tumors. Thirty (54.5%) patients were within the Milan criteria, and 25 (45.5%) were beyond. The mortality of study subjects at 30 days was 5.5%. Major complications were observed in five (9.1%) patients who were all beyond the Milan criteria: two hepatic failures, one hepatic encephalopathy, and two CTCAE grade 3 increases in aspartate aminotransferase/alanine aminotransferase abnormality. The mean length of hospitalization was 6.3 ± 8.3 days (standard deviation), and 18 (32.7%) patients were discharged on the next day after chemoembolization. The tumor responses of the patients who met the Milan criteria were significantly higher (p = 0.014) than those of the patients who did not. The overall median survival was 7.1 months (95% confidence interval: 4.4-9.8 months). Even in patients with Child-Pugh class C, chemoembolization can be performed safely with a selective technique in selected cases with a small tumor burden.

    Chronic hepatitis C virus (HCV)-infected patients with cirrhosis are a high-priority population for treatment. To help inform the benefit-risk profile of the all-oral direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir (OBV/PTV/r±DSV) in patients with Child-Pugh A cirrhosis, we undertook a comprehensive review of AbbVie-sponsored clinical trials enrolling patients with Child-Pugh A cirrhosis. Twelve phase II or III clinical trials of the 2-DAA regimen of OBV/PTV/r±ribavirin (RBV) or the 3-DAA regimen of OBV/PTV/r+DSV±RBV that included patients with Child-Pugh A cirrhosis were reviewed; patients who completed treatment by November 16, 2015 were included in a pooled, post hoc safety assessment. The number and percentage of patients with treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs consistent with hepatic decompensation were reported. In 1,066 patients with Child-Pugh A cirrhosis, rates of serious TEAEs and TEAEs leading to study drug discontinuation were 5.3% (95% confidence interval [CI]: 4.1-6.8) and 2.2% (95% CI: 1.4-3.2), respectively. Thirteen patients (1.2%; 95% CI: 0.7-2.1) had a TEAE that was consistent with hepatic decompensation. The most frequent TEAEs consistent with hepatic decompensation were ascites (n=8), esophageal variceal hemorrhage (n=4), and hepatic encephalopathy (n=2). This pooled analysis in 1,066 HCV-infected patients with Child-Pugh A cirrhosis confirms the safety of OBV/PTV/r±DSV±RBV in this population. These results support the use of OBV/PTV/r±DSV±RBV in this high-priority population. Lay summary: This pooled safety analysis in 1,066 HCV-infected patients with compensated cirrhosis, receiving treatment with ombitasvir, paritaprevir, and ritonavir with or without dasabuvir, with or without ribavirin, shows that the rate of hepatic decompensation events was similar to previously reported rates in untreated patients.

    Full Text Available To investigate whether liver lobe based T2* values measured on gradient recalled echo T2*-weighted imaging are associated with the presence and Child-Pugh class of hepatitis B-related cirrhosis.Fifty-six patients with hepatitis B-related cirrhosis and 23 healthy control individuals were enrolled in this study and underwent upper abdominal T2*-weighted magnetic resonance imaging. T2* values of the left lateral lobe (LLL, left medial lobe (LML, right lobe (RL and caudate lobe (CL were measured on T2*-weighted imaging. Statistical analyses were performed to determine the association between liver lobe based T2* values and the presence and Child-Pugh class of cirrhosis.The T2* values of the LLL, LML and RL decreased with the progression of cirrhosis from Child-Pugh class A to C (r = -0.231, -0.223, and -0.395, respectively; all P 0.05. To a certain extent, Mann-Whitney U tests with Bonferroni correction for multigroup comparisons showed that the T2* values of the LLL, LML and RL could distinguish cirrhotic liver from healthy liver (all P 0.05. Receiver operating characteristic analysis demonstrated that the T2* value of the RL could best distinguish cirrhosis from healthy liver, with an area under the receiver operating characteristic curve (AUC of 0.713 among T2* values of the liver lobes, and that only the T2* value of the RL could distinguish Child-Pugh class C from A-B, with an AUC of 0.697 (all P < 0.05.The T2* value of the RL can be associated with the presence and Child-Pugh class of hepatitis B-related cirrhosis.

    This study was designed to determine if existing methods of grading liver function that have been developed in non-Asian patients with cirrhosis can be used to predict mortality in Asian patients treated for refractory variceal hemorrhage by the use of the transjugular intrahepatic portosystemic shunt (TIPS) procedure. Data for 107 consecutive patients who underwent an emergency TIPS procedure were retrospectively analyzed. Acute physiology and chronic health evaluation (APACHE II), Child-Pugh and model for end-stage liver disease (MELD) scores were calculated. Survival analyses were performed to evaluate the ability of the various models to predict 30-day, 60-day and 360-day mortality. The ability of stratified APACHE II, Child-Pugh, and MELD scores to predict survival was assessed by the use of Kaplan-Meier analysis with the log-rank test. No patient died during the TIPS procedure, but 82 patients died during the follow-up period. Thirty patients died within 30 days after the TIPS procedure; 37 patients died within 60 days and 53 patients died within 360 days. Univariate analysis indicated that hepatorenal syndrome, use of inotropic agents and mechanical ventilation were associated with elevated 30-day mortality (p < 0.05). Multivariate analysis showed that a Child-Pugh score > 11 or an MELD score > 20 predicted increased risk of death at 30, 60 and 360 days (p < 0.05). APACHE II scores could only predict mortality at 360 days (p < 0.05). A Child-Pugh score > 11 or an MELD score > 20 are predictive of mortality in Asian patients with refractory variceal hemorrhage treated with the TIPS procedure. An APACHE II score is not predictive of early mortality in this patient population.

    Underlying liver cirrhosis is present in most patients with hepatocellular carcinoma, and liver transplantation is the only treatment strategy to cure both diseases. All other hepatocellular carcinoma treatment strategies have to take into account residual liver function that concurs with the patient's prognosis and might limit their feasibility. In patients with hepatocellular carcinoma and Child-Pugh-Turcotte class B (CPT-B), owing to borderline liver function, any intervention might be offset by liver function deterioration. In this setting, the decision for hepatocellular carcinoma treatment requires a comprehensive assessment of liver function, not restricted to the CPT classification, in addition to a careful evaluation of the prognostic effect of hepatocellular carcinoma compared with cirrhosis. In this Review, we provide an overview of the literature regarding the benefits and harms of non-transplant therapies in patients with hepatocellular carcinoma and CPT-B cirrhosis.

    Purpose: In contrast to hepatic resection (HR) for resectable early-stage HCC, the efficacy of transarterial chemoembolization (TACE) is controversial. This study is designed to compare the long-term outcome of TACE using superselective technique with hepatic resection for the treating resectable early-stage HCC and Child-Pugh class A liver function. Methods: In total, 185 consecutive patients with resectable early-stage HCC and Child-Pugh class A liver function were included: 73 patients received superselective TACE (group I) and 112 patients underwent HR (group II). We evaluated the therapy-related recurrence and long-term outcome and in both groups. The risk factors of recurrence and mortality were assessed by Cox's model. Results: The mean survival time of group 1 patient was similar to that of group 2 patient (40.8 ± 19.8 vs 46.7 ± 24.6 months respectively, p = 0.91). The 1-, 3-, and 5-year overall survival rates after TACE (group I)and HR (group II) were 91%, 66%, and 52% and 93%, 71%, and 57%, respectively (p = 0.239). The 1-, 3-, and 5-year recurrence-free survival rates in groups 1 and 2 were 68%, 28%, and 17% and 78%, 55%, and 35%, respectively (p < 0.0001). Serum albumin, tumour size, tumour number and recurrence interval were independent risk factors for mortality. Serum albumin level, tumour size, tumour number, and treatment modality of TACE or HR could predict HCC recurrence. Conclusion: TACE is an efficient and safe treatment for resectable early-stage HCC with overall survival rates similar to that of HR. Thus, TACE is indicated in selected patients with resectable early-stage HCC.

    Renal dysfunction (RD) is a serious and common complication in a patient with liver cirrhosis. It provides a poor prognosis. The aim of our study was to evaluate the renal function in liver cirrhosis, also to determine the correlation with the graduation of liver disease assessed by Child-Pugh Score (CPS) and MELD score. This was a cross-sectional study included patients with liver cirrhosis admitted to Adam Malik Hospital Medan in June - August 2016. We divided them into two groups as not having renal dysfunction (serum creatinine SPSS 22.0 was used. Statistical methods used: Chi-square, Fisher exact, one way ANOVA, Kruskal Wallis test and Pearson coefficient of correlation. The level of significance was p<0.05. 55 patients with presented with renal dysfunction were 16 (29.1 %). There was statistically significant inverse correlation between GFR and CPS (r = -0.308), GFR and MELD score (r = -0.278). There was a statistically significant correlation between creatinine and MELD score (r = 0.359), creatinine and CPS (r = 0.382). The increase of the degree of liver damage is related to the increase of renal dysfunction.

    The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. The median follow up duration was 16.2 months (range: 1.0-124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC. © 2018 Wiley Periodicals, Inc.

    Purpose: To report outcomes in patients with Child-Pugh B or C (CP B/C) hepatocellular carcinoma (HCC) treated with stereotactic body radiotherapy (SBRT). Methods and materials: A prospective study of SBRT was developed for patients with CP B7 or B8 unresectable HCC, <10 cm. Selected ineligible patients (e.g. CP > B8, >10 cm) treated off-study from 2004 to July 2012 were also reviewed. Patients were excluded if they were treated as a bridge-to-liver-transplant. Results: 29 patients with CP B/C HCC were treated with SBRT (median dose 30 Gy in 6 fractions) from 2004 to December 2012. The majority had CP B7 liver function (69%) and portal vein tumor thrombosis (76%). The median survival was 7.9 months (95% CI: 2.8–15.1). Survival was significantly better in patients with CP = B7 and AFP ⩽ 4491 ng/mL. Of 16 evaluable patients, 63% had a decline in CP score by ⩾2 points at 3 months. Conclusion: SBRT is a treatment option for selected HCC patients with small HCCs and modestly impaired (CP B7) liver function

    The indocyanine green (ICG) retention test is the most popular liver function test for selecting patients for major hepatectomy. Traditionally, it is done using spectrophotometry with serial blood sampling. The newly-developed pulse spectrophotometry is a faster alternative, but its accuracy on Child-Pugh A cirrhotic patients undergoing hepatectomy for hepatocellular carcinoma has not been well documented. This study aimed to assess the accuracy of the LiMON(®), one of the pulse spectrophotometry systems, in measuring preoperative ICG retention in these patients and to devise an easy formula for conversion of the results so that they can be compared with classical literature records where ICG retention was measured by the traditional method. We measured the liver function of 70 Child-Pugh A cirrhotic patients before hepatectomy for hepatocellular carcinoma from September 2008 to January 2009. ICG retention at 15 minutes measured by traditional spectrophotometry (ICGR15) was compared with ICG retention at 15 minutes measured by the LiMON (ICGR15(L)). The median ICGR15 was 14.7% (5.6%-32%) and the median ICGR15(L) was 10.4% (1.2%-28%). The mean difference between them was -4.3606. There was a strong correlation between ICGR15 and ICGR15(L) (correlation coefficient, 0.844; 95% confidence interval, 0.762-0.899). The following formula was devised: ICGR15=1.16XICGR15(L)+2.73. The LiMON provides a fast and repeatable way to measure ICG retention at 15 minutes, but with constant underestimation of the real value. Therefore, when comparing results obtained by traditional spectrophotometry and the LiMON, adjustment of results from the latter is necessary, and this can be done with a simple mathematical calculation using the above formula.

    Full Text Available The gut flora are widely involved in the cometabolism with the host and have evident effects on the metabolic phenotype of host. This study performed a metabolome analysis of the intestinal microbiota specific for liver cirrhosis. The study population included patients with Child-Turcotte-Pugh (CTP score of A (AP, n=5 and B (BP, n=5, and control subjects (NM, n=3. Metagenomic DNA from fecal microbiota was extracted followed by metagenomic sequenceing through Illumina MiSeq high throughput sequencing of 16S rRNA regions. The detection of metabolites from fecal samples was performed using high-performance liquid phase chromatography and gas chromatography coupled with tandem mass spectrometry (HPLC-GC/MS-MS. Intestinal microbiota community and metabolite analysis both showed separation of cirrhotic patients from control participants, moreover, the microbiota-metabolite correlations changed in cirrhotic patients. Fecal microbiota from cirrhotic patients, with the reduced diversity, contained a decreased abundance of Bacteroidetes and an increased abundance of Proteobacteria compared with the normal samples. Analysis of metabolome revealed a remarkable change in the metabolic potential of the microbiota in cirrhotic patients, with specific higher concentrations of amine, unsaturated fatty acid, and SCFAs (short-chain fatty acids, and lower concentrations of sugar alcohol and amino acid, suggesting the initial equilibrium of gut microbiota community and co-metabolism with the host were perturbed by cirrhosis. Our study illustrated the relationship between fecal microbiota composition and metabolom in cirrhotic patients, which may improve the clinical prognosis of cirrhosis.

    Currently, most liver units use the Child-Pugh (CP) or the Model for End-Stage Liver Disease (MELD) scores to establish survival prognosis among patients with liver cirrhosis. Which classification is superior, is not well defined. To compare CP and MELD classification scores to predict survival among adult patients with liver cirrhosis in Chile. Follow-up of 137 consecutive adult patients with liver cirrhosis aged 59 ± 12 years (55% women). The diagnosis was reached by clinical, laboratory and image studies at three different centers of Santiago. Patients were staged with CP and MELD classification scores at baseline and followed over a period of 12 months. The predictive capacity of the scores for survival was analyzed using a multivariate statistical analysis (Kaplan-Meier curves). The most common etiology was alcohol (37.9%). The actuarial survival rate was 79.6% at 12 months of follow-up. When comparing groups with areas under curve of receiver operating characteristic curves (AUROC), there was no statistically significant difference in survival between less severe and advanced disease, assessed with both survival scales. The AUROC for MELD and CP were 0.80 and 0.81, respectively. This clinical study did not find a statistically significant difference between the two classifications for the prediction of 12 months survival in patients with cirrhosis.

    To compare Model for End Stage Liver Disease (MELD) and Child-Turcott-Pugh (CTG) scoring as predictors of survival in cirrhotic patients. Study Design: Observational prospective study. Place and Duration of Study: Military Hospital, Rawalpindi from 1st Dec 2008 to 30th April 2009. Material and Methods: The study was carried out at Military Hospital, Rawalpindi a tertiary care hospital of Pakistan. Study included 55 patients suffering from cirrhosis of both genders being above 12 years of age, admitted in medical wards during the period from 1st December, 2008 to 30th April 2009. Each patient was assigned a MELD and CTP score. On discharge, these patients were followed up at 03 months, 06 months and 1 year duration through telephone. Results: Thirty seven (67.3%) patients were male while 18 (32.7%) were female patients, with age ranging from 27 years to 75 years (mean 53). Fourteen (25.4%) patients were dead at 3-months, 22 patients (40%) were dead at 6-months and 29 (52.7%) patients were dead at 1 year follow up. MELD score proved to be a better indicator of survival than CTP score over a period of 01 year follow-up. Conclusion: MELD score is a better prognostic marker for cirrhotic patients as compared to CTP score. (author)

    To investigate the safety of high dose hypofractionated radiotherapy (RT) in patients with small hepatocellular carcinoma (HCC) in terms of liver volumetric changes and clinical liver function. We retrospectively reviewed 16 patients with small HCC who were treated with high dose hypofractionated RT between 2006 and 2009. The serial changes of the liver volumetric parameter were analyzed from pre-RT and follow-up (FU) computed tomography (CT) scans. We estimated linear time trends of whole liver volume using a linear mixed model. The serial changes of the Child-Pugh (CP) scores were also analyzed in relation to the volumetric changes. Mean pre-RT volume of entire liver was 1,192.2 mL (range, 502.6 to 1,310.2 mL) and mean clinical target volume was 14.7 mL (range, 1.56 to 70.07 mL). Fourteen (87.5%) patients had 4 FU CT sets and 2 (12.5%) patients had 3 FU CT sets. Mean interval between FU CT acquisition was 2.5 months. After considering age, gender and the irradiated liver volume as a fixed effects, the mixed model analysis confirmed that the change in liver volume is not significant throughout the time course of FU periods. Majority of patients had a CP score change less than 2 except in 1 patient who had CP score change more than 3. The high dose hypofractionated RT for small HCC is relatively safe and feasible in terms of liver volumetric changes and clinical liver function.

    Objective: To determine the value of clinical and CT assessment of hepatic reserve function in patients with cirrhosis and liver cancer undergoing transcatheter arterial chemoembolization (TACE). Methods: Sixty consecutive patients with cirrhosis and primary liver cancer treated using TACE were studied prospectively. The hepatic reserve function was evaluated using Child-Pugh classification and modified Child-Pugh classification before and after TACE respectively. The modified Child-Pugh classification was an integration of Child-Pugh classification, morphological evaluation of the cirrhotic liver and measurement of tumor-free liver volume by CT. Agreement rates of the two methods for assessing the hepatic reserve function peri-operatively and the survival time were calculated. Results: The agreement rates of Child-Pugh classification and modified Child-Pugh classification for assessing the postoperative hepatic reserve function were 55.6% and 83.3% respectively in well-compensated cases (P 2 =11.2, 8.7, 13.5, P<0.001) shorter than that of patients in modified Child-Pugh classes A (71 months), B (46 months) and C (7.6 months). Conclusion: Modified Child-Pugh classification is better than Child-Pugh classification for assessing the hepatic reserve function in patients with cirrhosis and liver cancer undergoing TACE.

    Full Text Available Majority of patients with hepatocellular carcinoma (HCC belonged to Child-Turcotte-Pugh (CTP class A. We aimed to identify a new class of patients with very well-preserved liver function and analyze its impact on outcome prediction, tumor staging and treatment allocation.A total of 2654 HCC patients were retrospectively analyzed. The prognostic ability was compared by the Akaike information criterion (AIC.The CTP class 0 was defined by fulfilling all criteria of albumin ≧4 g/dL, bilirubin ≦0.8 mg/dL, prothrombin time prolongation <0 seconds, no ascites and encephalopathy. A total of 23% of patients of CTP class A were reclassified as CTP class 0. Patients with CTP class 0 had a higher serum sodium level, lower serum creatinine, alanine aminotransferase, α-fetoprotein levels, shorter prothrombin time, better general well-being, smaller tumor burden with more solitary nodules, lower rates of vascular invasion, ascites formation, hepatic encephalopathy, more frequently treated with curative interventions and better Barcelona Clinic Liver Cancer (BCLC stages (all p<0.001. In the Cox proportional hazards model, the adjusted hazard ratios for CTP class A, B and C were 1.739, 3.120 and 5.107, respectively, compared to class 0 (all p<0.001. Reassigning patients with CTP class 0, A, B, B and C to stage 0, A, B, C and D, respectively, provided the lowest AIC score among all BCLC-based models.The proposal of CTP class 0 independently predicted better survival in HCC patients. Modification of tumor staging systems according to the modified CTP classification further enhances their prognostic ability.

    Objective: To identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT). Methods: A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis, 93 patients in class A and 16 in class B. The mean dose of radiation to the isocenter was (53.5±5.5) Gy, fractions of (4.8±0.5) Gy, with interfraction interval of 48 hours and irradiation 3 times per week. Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients; Child-Pugh A and Child-Pugh B patients, respectively. Results: Of all the patients, 17 developed RILD (17/109), 8 in Child-Pugh A (8/93) and 9 in Child-Pugh B (9/16). By multivariate analysis, only the Child-Pugh Grade of liver cirrhosis was the independent factor (P=0.000) associated with the developing of BILD. The best estimates of the NTCP parameters for all 109 patients were n=1.1, m=0.35 and TD 50 (1)=38.5 Gy. The n, m, TD 50 (1) estimated from patients with Child-Pugh A was 1.1, 0.28, 40.5 Gy, respectively, compared with 0.7, 0.43, 23 Gy respectively, for patients with Child-Pugh B. Conclusions: Primary liver cancer patients who possess Child-Pugh B cirrhosis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis. The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients. (authors)

    To investigate the differences in signal changes in the globus pallidus and white matter, as seen on T1-weighted MR brain images, and to determine whether these differences can be used as an indicator of subclinical hepatic encephalopathy. A total of 25 cases of liver cirrhosis were evaluated and as a control group, 20 subjects were also studied. Using a 1.5T MRI scannet, brain MR images were obtained, and the differences in signal intensity in both the globus pallidus and thalamus and in both white and gray matter were then quantified using the contrast to noise ratio(CNR). On the basis of the Child-Pugh classification, 25patients with liver cirrhosis were divided into three groups, with eight in group A, eight in B, and nine in C. Using clinical criteria, hepatic encephalopathy was diagnosed in seven of the 25 patients. There after, CNRs(CNR1 and CNR2) were conpared between the control and cirrhotic groups and between cirrhotic groups with or without hepatic encephalopathy. In the control group, mean values were 3.2±5.9 for CNR1 and 8.4±8.0 for CNR2. In the cirrhotic group, these values were 10.6±9.0 for CNR1 and 9.8±6.4 for CNR2. A statistically significant difference was noted between normal and cirrhotic groups only for CNR1(p<0.05). CNR values in patients with liver cirrhosis were 8.5±11.5 for CNR1 and 11.7±8.7 for CNR2 in the Child A group, 10.4±5.1 for CNR1 and 9.3±3.2 for CNR2 in the B group, and 12.8±9.7 for CNR1 and 8.7±6.5 for CNR2 in the C group. There was no significant difference in mean CNRI values between patients with or without hepatic encephalopathy. Differences in signal intensities in the globus pallidus and white matter, as seen on T1-weighted MR brain images, cannot be used as an indicator of hepatic encephalopathy in patients with liver cirrhosis

    Purpose: To describe the probability of RILD by application of the Lyman-Kutcher-Burman normal-tissue complication (NTCP) model for primary liver carcinoma (PLC) treated with hypofractionated three-dimensional conformal radiotherapy (3D-CRT). Methods and Materials: A total of 109 PLC patients treated by 3D-CRT were followed for RILD. Of these patients, 93 were in liver cirrhosis of Child-Pugh Grade A, and 16 were in Child-Pugh Grade B. The Michigan NTCP model was used to predict the probability of RILD, and then the modified Lyman NTCP model was generated for Child-Pugh A and Child-Pugh B patients by maximum-likelihood analysis. Results: Of all patients, 17 developed RILD in which 8 were of Child-Pugh Grade A, and 9 were of Child-Pugh Grade B. The prediction of RILD by the Michigan model was underestimated for PLC patients. The modified n, m, TD 5 (1) were 1.1, 0.28, and 40.5 Gy and 0.7, 0.43, and 23 Gy for patients with Child-Pugh A and B, respectively, which yielded better estimations of RILD probability. The hepatic tolerable doses (TD 5 ) would be MDTNL of 21 Gy and 6 Gy, respectively, for Child-Pugh A and B patients. Conclusions: The Michigan model was probably not fit to predict RILD in PLC patients. A modified Lyman NTCP model for RILD was recommended

    Background As gadoxetic acid-enhanced magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) have been widely used for the evaluation of hepatocellular carcinoma (HCC), it is clinically relevant to determine the diagnostic efficacy of gadoxetic acid-enhanced MRI and DWI for detection of HCCs with respect to the severity of liver cirrhosis. Purpose To compare the diagnostic accuracy and sensitivity of gadoxetic acid-enhanced MRI and DWI for detection of HCCs with respect to the severity of liver cirrhosis. Material and Methods A total of 189 patients with 240 HCCs (≤3.0 cm) (Child-Pugh A, 81 patients with 90 HCCs; Child-Pugh B, 65 patients with 85 HCCs; Child-Pugh C, 43 patients with 65 HCCs) underwent DWI and gadoxetic acid-enhanced MRI at 3.0 T. A gadoxetic acid set (dynamic and hepatobiliary phase plus T2-weighted image) and DWI set (DWI plus unenhanced MRIs) for each Child-Pugh class were analyzed independently by two observers for detecting HCCs using receiver-operating characteristic analysis. The diagnostic accuracy and sensitivity were calculated. Results There was a trend toward decreased diagnostic accuracy for gadoxetic acid and DWI set with respect to the severity of cirrhosis (Child-Pugh A [mean 0.974, 0.961], B [mean 0.904, 0.863], C [mean 0.779, 0.760]). For both observers, the sensitivities of both image sets were highest in Child-Pugh class A (mean 95.6%, 93.9%), followed by class B (mean 83.0%, 77.1%), and class C (mean 60.6%, 60.0%) (P < 0.05). Conclusion In HCC detection, the diagnostic accuracy and sensitivity for gadoxetic acid-enhanced MRI and DWI were highest in Child-Pugh class A, followed by Child-Pugh class B, and Child-Pugh class C, indicating a tendency toward decreased diagnostic capability with the severity of cirrhosis

    We aimed to elucidate the incidence of protein-energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM.A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less than 0.85 as those with PEM. We compared between patients with PEM and those without PEM in baseline characteristics and examined factors linked to the presence of PEM using univariate and multivariate analyses.There are 216 patients with chronic hepatitis, 123 with Child-Pugh A, 80 with Child-Pugh B, and 13 with Child-Pugh C. Six patients (2.8%) had PEM in patients with chronic hepatitis, 17 (13.8%) in patients with Child-Pugh A, 42 (52.5%) in patients with Child-Pugh B, and 10 (76.9%) in patients with Child-Pugh C (P < 0.001). Multivariate analysis revealed that Child-Pugh classification (P < 0.001), age ≥64 years (P = 0.0428), aspartate aminotransferase (AST) ≥40 IU/L (P = 0.0023), and branched-chain amino acid to tyrosine ratio (BTR) ≤5.2 (P = 0.0328) were independent predictors linked to the presence of PEM. On the basis of numbers of above risk factors (age, AST, and BTR), the proportions of patients with PEM were well stratified especially in patients with early chronic hepatitis or Child-Pugh A (n = 339, P < 0.0001), while the proportions of patients with PEM tended to be well stratified in patients with Child-Pugh B or C (n = 93, P = 0.0673).Age, AST, and BTR can be useful markers for identifying PEM especially in patients with early stage of chronic liver disease.

    Background Pulmonary dysfunctions including the hepatopulmonary syndrome and portosystemic shunt are important complications of hepatic cirrhosis. To investigate the severity and nature of abnormal gas diffusing capacity and its correlation to portosystemic shunt in patients with chronic liver disease. Methods Forty-four patients with chronic liver disease (15 chronic active hepatitis (CAH), 16 Child-Pugh class A, and 13 Child-Pugh class B) without other diseases history were enrolled in the study. Evaluation of liver function tests, arterial blood gases analysis, ultrasonography, pulmonary function test including lung diffusing capacity of carbon monoxide (DLco), forced vital capacity(FVC), forced expiratory volume 1 seconds(FEV1), total lung capacity(TLC), DLco/AV(alveolar volume) and thallium-201 per rectum scintigraphy were performed. We were analyzed correlations between pulmonary function abnormalities and heart/liver (H/L) ratio in patients with chronic liver diseases. Results In CAH, percentage of patients with DLco and DLco/VA (Child-Pugh class A and B patients. The means of DLco and DLco/VA were significantly (P Child-Pugh class. The mean H/L ratio in Child-Pugh class B increased markedly (P Child-Pugh class A. The frequency of specific pulmonary function abnormality in patients with Child-Pugh class B was significantly (P Child-Pugh class A and CAH. There was a inverse linear correlation between H/L ratio and DLco (r = -0.339, P < 0.05) and DLco/VA (r = -0.480, P < 0.01). Conclusion A total of 62% of patients with advanced liver disease have abnormal pulmonary diffusion capacity with a reduced DLco or DLco/VA and abnormal portosystemic shunt (increased H/L ratio) is common hemodynamic abnormality. Therefore, inverse linear correlation between DLco or DLco/VA and H/L ratio may be an important factor in predicting pulmonary complication and meaningful diagnostic and prognostic parameters in patients with advanced chronic liver disease.

    Purpose: The Child-Pugh score is often used to judge the outcome of radiotherapy for hepatocellular carcinoma (HCC). The retention rate of indocyanine green 15 min after administration (ICG R15) can also be used to predict prognosis after liver resection. We evaluated the utility of ICG R15 for prediction of outcomes after proton beam therapy (PBT) for HCC. Methods and materials: A retrospective evaluation was performed in 250 patients who received PBT between 2002 and 2007. The patients (178 males and 72 females) had a median age of 71 years (range: 43–88). Child-Pugh categories were A (score 5–6), B (7–9), and C (10–15) in 197, 51, and 2 patients, respectively. ICG scores were 0–<10, 10–<20, 20–<30, 30–<40 and ⩾40 in 27, 99, 59, 28 and 37 patients, respectively; including 26, 92, 45, 16 and 18 Child-Pugh A patients and 1, 8, 14, 11, and 17 Child-Pugh B patients, respectively. Survival times from the start of PBT were compared between Child-Pugh A and B patients, and among each ICG group. Results: The median survival times were 61 months (95% CI: 50–72 months) in all patients, and 64 and 20 months in Child-Pugh A and B patients, respectively (p = 0.001), The 3-year survival rates were 72%, 72%, 75%, 63%, and 26% in patients with ICG scores of 0–<10, 10–<20, 20–<30, 30–<40, and ⩾40 (p = 0.001); 70%, 75%, 77%, 65%, and 38% in these respective groups in Child-Pugh A patients (p = 0.02); and 100%, 57%, 67%, 36%, and 14% in Child-Pugh B patients (p = 0.173, not significant). Multivariate analysis showed that low ICG R15 and the absence of portal vein tumor thrombus were associated with good survival. Conclusions: Pretreatment ICG R15 is a useful prognostic factor for prediction of outcome of PBT in HCC patients, especially in those with Child-Pugh A liver function

    In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy (ERCP) in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients (P>0.05). The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients (4.35%, 2/46) who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher (25%, 2/8) than that (3%, 3/100) in non-cirrhotic patients (Pbile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

    Red blood cell distribution width (RDW) is a measure of the variation of red blood cell width that is reported as apart of standard complete blood count. Red blood cell distribution width results are often used together with mean corpuscular volume (MCV) results to figure out mixed anemia. The aim of our study was to compare the values of RDW in alcoholic and non-alcoholic liver cirrhosis and to determine if RDW follows the severity of disease according to Child-Pugh score. We retrospectively analyzed 241 patients (176 men and 65 women) with liver cirrhosis and anemia, defined as a hemoglobin value reference range is 11-15%. Alcoholic liver cirrhosis had 204 patients (85%) while non-alcoholic cirrhosis had 37 patients (15%). In group of alcoholic cirrhosis the average RDW was 16.8%. In relation to severity of disease the average RDW for Child-Pugh A was 16.80%, for Child-Pugh B was 16.92%, for Child-Pugh C was 17.10%. In the group of non-alcoholic cirrhosis the average RDW was 16.73% and in relation to severity of disease for Child-Pugh A was 16.25%, for Child-Pugh B 17.01% and for Child-Pugh C was 16.87%. We didn't find statistically significant difference of RDW between alcoholic and non alcoholic cirrhosis (p > 0.05) and we didn't proved any statistically significant increase of RDW in relation to severity of disease in group of alcoholic cirrhosis (p = 0.915) nor in group of patients with non-alcoholic cirrhosis (p = 0.697). Our study showed that RDW had not any clinical value in differentiation of anemia neither in alcoholic and non-alcoholic liver cirrhosis nor in severity of liver disease.

    Objective: To identify the risk factors of radiation-induced liver disease (RILD) after three-dimensional radiotherapy (3DCRT) for primary liver carcinoma (PLC) and the dosimetric threshold of RILD. Methods: Between April 1999 and August 2003, 128 PLC patients who were treated with 3DCRT received a mean dose of 53.6 ± 6.6 Gy with a 4-8 Gy/f, 3f/w, qod regimen. The relation between RILD and the possible clinical factors, such as gender, age, UICC/ AJCC T stage, GTV, HBV status, PTV, TACE, Child-Pugh grade of liver cirrhosis, BED calculated by LQ model and fraction size were analyzed. Among 84 patients who had full dose- volume histogram (DVH) data, the relation between RILD and dosimetric parameters were analyzed. Results: Nineteen patients (14.8%) developed RILD. It was found that T stage, GTV, PTV, Child-Pugh grade of liver cirrhosis and the acute hepatic toxicity proposed by common toxicity criteria version 2.0 (CTC2.0) were correlated with RILD (P=0.024, 0.002, 0.001, 0.000, 0.000, respectively). Multivariate analysis showed that only the Child-Pugh grade of liver cirrhosis was independent factor (P=0.000). The mean liver dose was significantly higher in patients with RILD (P=0.027). In patients with Child-Pugh grade A, V5 (percentage of normal liver volume with radiation dose > 5 Gy), V 10 and V 20 ≤81%, 69% and 42%, mean liver dose ≤28 Gy, RILD was not observed, whereas in patients with Child-Pugh grade B, the possibility of developing RILD was 53.3%(8/15). Conclusions: Comprehensive consideration of T stage, GTV, PTV and Child-Pugh grade of liver cirrhosis, especially the Child-Pugh grade of liver cirrhosis, when planning 3DCRT for PLC, may lower the incidence of RILD.

    The assessment of prognosis is an essential part of the evaluation of all patients with liver cirrhosis. Currently continues to develop new models to optimize forecast accuracy mortality score is calculated by the Child-Turcotte-Pugh (CTP) and the model for end-stage liver disease (MELD). Compare the prognostic accuracy of hospital mortality and short-term mortality CTP, MELD and other models in patients with decompensated liver cirrhosis. Prospective descriptive study, comparison type of diagnostic test that included 84 patients. The score CTP, MELD and other models were calculated on the first day of hospitalization. The prognostic accuracy of mortality was assessed by the area under the ROC curve (AUROCs) of score CTP, MELD and other models. Hospital mortality and mortality in the short-term monitoring was 20 (23.8%) and 44 (52.4%), respectively. The AUROCs CTP, MELD, MELD Na, MESO, iMELD, RefitMELD and RefitMELD Na to predict hospital mortality was 0.4488, 0.5645, 0.5426, 0.5578, 0.5719, 0.5598 and 0.5754; and to predict short-term mortality was 0.5386, 0.5747, 0.5770, 0.5781, 0.5631, 0.5881 and 0.5693, respectively. By comparing each AUROCs of the CTP score, MELD and other models proved to be no better than the other (p>0.05). This study has not shown the predictive utility of the CTP score, MELD and other models (MELD Na, MESO, iMELD, Refit Refit MELD and MELD Na) to evaluate hospital mortality or short-term mortality in a sample of patients with decompensated cirrhosis of the Hospital Cayetano Heredia.

    Full Text Available This study aimed to evaluate the dynamic computed tomographic (CT appearance of focal radiation injury to cirrhotic liver tissue around the tumor following stereotactic body radiation therapy (SBRT for hepatocellular carcinoma (HCC. Seventy-seven patients with 92 HCCs were observed for >6 months. Sixty-four and 13 patients belonged to Child-Pugh class A and B, respectively. The median SBRT dose was 48 Gy/4fr. Dynamic CT scans were performed in non-enhanced, arterial, portal, and venous phases. The median follow-up period was 18 months. Dynamic CT appearances were classified into 3 types: type 1, hyperdensity in all enhanced phases; type 2, hypodensity in arterial and portal phases; type 3, isodensity in all enhanced phases. Half of the type 2 or 3 appearances significantly changed to type 1, particularly in patients belonging to Child-Pugh class A. After 3-6 months, Child-Pugh class B was a significant factor in type 3 patients. Thus, dynamic CT appearances were classified into 3 patterns and significantly changed over time into the enhancement group (type 1 in most patients belonging to Child-Pugh class A. Child-Pugh class B was a significant factor in the non-enhancement group (type 3.

    Viral hepatitis is among the important health problems in Egypt which lead to chronic hepatitis and liver cirrhosis.Liver cirrhosis is associated with circulatory disturbances which are attributed to arterial vasodilatation that results from overproduction or reduced degradation of vasodilator substances. Adrenomedullin (AM) is responsible for the arteriolar vasodilatation and hyper dynamic circulation in liver cirrhosis. The aim of work was to the assessment patients with chronic hepatitis and liver cirrhosis with or without renal impairment by determining the level of AM and comparing them with healthy controls. 44 patients with chronic liver diseases (14 patients with chronic hepatitis and 30 patients with liver cirrhosis, 16 in Child-Pugh's class A, 8 in Child-Pugh's class B, and 6 in Child-Pugh's class C) were examined clinically, laboratory, ultrasonography and endoscopically. Plasma concentration of adrenomedullin was measured in all patients and 15 normal controls.The mean levels of AM were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.52 ± 0.19 ng/ml , 0.67 ± 0.16 ng/ml and 0.35 ± 0.12 ng/ml, respectively; p<0.001). The mean levels of plasma aldosterone concentration were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (256 ± 197 ng/dl 358 ± 264 ng/dl and 179 ± 142 ng/dl, respectively; p<0.001). The mean levels of creatinine clearance were lower in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.31±0.19 ml/min 0.25±0.21 ml/min and 0.45±0.37 ml/min, respectively; p<0.001). The mean levels of AM were higher in patients with liver cirrhosis with renal impairment than without. Also there was significant difference in AM levels between patients with and without esophageal varices (0.71 ± 0.22 ng/ml and 0.52 ± 0.17 ng/ml respectively, p<0.05).

    Objective: To determine the association of serum cholesterol levels with Child-Pugh class in patients with decompensated chronic liver disease due to viral hepatitis. Methodology: Consecutive patients attending outpatient department or admitted in medical unit III were eligible if they had a diagnosis of cirrhosis secondary to viral hepatitis. Patients were excluded if alcoholic, diabetic, hypertensive, or with non-alcoholic fatty liver disease, autoimmune, metabolic, cardiovascular, cerebrovascular or kidney diseases and recent use of lipid-regulating drugs. Serum lipid profile was determined after an overnight fast of 12 hours. On the basis of serum total cholesterol, patients were divided into four groups; Group I with serum total cholesterol = 100 mg/dl, Group II with level of 101-150 mg/dl, Group III with level of 151-200 mg/dl and Group IV with serum total cholesterol level of > 200 mg/dl. Hepatic dysfunction was categorized according to Child-Pugh scoring system. Chi-square and Spearman's correlation testing with p < 0.05 was accepted as significant. Results: One hundred and fourteen patients met the inclusion criteria with a mean age of 40.32 +- 13.59 years. Among these 32 were females (28.1%) while 82 were males (71.9%). According to Child-Pugh class; 34 patients (29.8%) presented with Child-Pugh class A, 34 (29.8%) in class B and 46 (40.4%) were in class C. Serum cholesterol (total) and triglycerides had significant association with Child-Pugh class (p = 0.0001 and p = 0.004 respectively) suggesting that as severity of liver dysfunction increases; serum cholesterol and triglycerides levels decrease. Results also revealed that males were significantly more hypocholesterolemic than females (p = 0.006). Conclusion: Hypocholesterolemia is a common finding in decompensated chronic liver disease and has got significant association with Child-Pugh class. It may increase the reliability of Child-Pugh classification in assessment of severity and prognosis in

Hematologic and biochemical markers were assessed at the pre-RFA period and 1 day, 2-3 days, and 1-2 weeks after RFA. We classified the subjects into two groups: Child-Pugh A (n=41 and Child-Pugh B (n=24. The ablative margin volume (AMV of each patient was measured. We analyzed the changes in laboratory profiles from the baseline, and investigated whether these laboratory changes were correlated with the AMV and the Child-Pugh classification.ResultsMost of the laboratory values peaked at 2-3 days after RFA. AMV was significantly correlated with changes in WBC count, hemoglobin level, and serum total bilirubin level (Pearson's correlation coefficient, 0.324-0.453; P<0.05. The alanine aminotransferase (ALT level varied significantly over time (P=0.023.ConclusionsMost of the measured laboratory markers changed from baseline, peaking at 2-3 days. The ALT level was the only parameter for which there was a significant difference after RFA between Child-Pugh A and B patients: it increased significantly more in the Child-Pugh A patients.

    Dexketoprofen trometamol, a high water-soluble salt of the active enantiomer of rac-ketoprofen, is a nonsteroidal antiinflammatory drug (NSAID) used for pain relief. This study compared the pharmacokinetics of dexketoprofen in patients with impaired liver function and normal subjects following single and repeated oral dosing. Subjects with normal liver function (n = 6) and with Child-Pugh A (n = 7) or Child-Pugh B (n = 5) hepatic impairment scores completed this open-label and parallel study. They received 25 mg dexketoprofen (equivalent to 37 mg of its tromethamine salt) as a single (day 1) and a 3-day repeated dose (1 dose every 8 hours for a total of 10 doses). Dexketoprofen concentrations were determined in plasma and urine by reverse-phase high performance liquid chromatography (HPLC). Model-independent pharmacokinetic parameters were obtained. All subjects completed the study. No serious adverse events were recorded. Following the single dose, mean (+/- SEM) Cmax were 3027.7 +/- 429.3 ng/ml (healthy subjects), 2856.3 +/- 340.3 ng/ml (Child-Pugh A) and 1937.2 +/- 328.0 ng/ml (Child-Pugh B). Median tmax were 0.49 h (0.33-0.68) h, 0.50 h (0.33-0.67) h and 0.67 h (0.33-1.50) h. AUC0-x averaged 3778.0 +/- 439.0 ng.h/ml, 4890.4 +/- 539.1 ng.h/ml and 3985.0 +/- 712.0 ng.h/ml. Mean CL/F were 101.1 +/- 11.3 ml/h/kg, 73.3 +/- 9.9 ml/h/kg and 88.8 +/- 15.5 ml/h/kg and V/F averaged 0.192 +/- 0.018 l/kg, 0.162 +/- 0.006 l/kg and 0.214 +/- 0.044 l/kg. Following the repeated administration, similar results were obtained showing no drug accumulation. As related to the administered dose, median excretions of unchanged and conjugated dexketoprofen in urine were 2.1% and 67.1% in healthy subjects, 2.8% and 60.9% in Child-Pugh A subjects and 4.4% and 47.7% in Child-Pugh B volunteers. A trend towards a reduced urinary excretion of conjugated dexketoprofen in hepatic patients, more evident in the Child-Pugh B than in the Child-Pugh A groups, was observed when compared with healthy

    To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) in patients with infiltrative hepatocellular carcinoma (HCC) and to identify the prognostic factors associated with patient survival. Fifty two patients who underwent TACE for infiltrative HCC were evaluated between 2007 and 2010. The maximum diameter of the tumors ranged from 7 cm to 22 cm (median 15 cm). Of 46 infiltrative HCC patients with portal vein tumor thrombosis, 32 patients received adjuvant radiation therapy for portal vein tumor thrombosis after TACE. The tumor response by European Association for the Study of the Liver criteria was partial in 18%, stable in 47%, and progressive in 35% of the patients. The median survival time was 5.7 months (Kaplan-Meier analysis). The survival rates were 48% at six months, 25% at one year, and 12% at two years. In the multivariable Cox regression analysis, Child-Pugh class (p = 0.02), adjuvant radiotherapy (p 0.003) and tumor response after TACE (p = 0.004) were significant factors associated with patient survival. Major complications occurred in nine patients. The major complication rate was significantly higher in patients with Child-Pugh B than in patients with Child-Pugh A (p = 0.049, x 2 test). Transcatheter arterial chemoembolization can be a safe treatment option in infiltrative HCC patients with Child Pugh class A. Child Pugh class A, radiotherapy for portal vein tumor thrombosis after TACE and tumor response are good prognostic factors for an increased survival after TACE in patients with infiltrative HCCs.

    To investigate variables before sorafenib therapy on the clinical outcomes in hepatocellular carcinoma (HCC) patients receiving sorafenib and to further assess and compare the predictive performance of continuous parameters using time-dependent receiver operating characteristics (ROC) analysis. A total of 225 HCC patients were analyzed. We retrospectively examined factors related to overall survival (OS) and progression free survival (PFS) using univariate and multivariate analyses. Subsequently, we performed time-dependent ROC analysis of continuous parameters which were significant in the multivariate analysis in terms of OS and PFS. Total sum of area under the ROC in all time points (defined as TAAT score) in each case was calculated. Our cohort included 175 male and 50 female patients (median age, 72 years) and included 158 Child-Pugh A and 67 Child-Pugh B patients. The median OS time was 0.68 years, while the median PFS time was 0.24 years. On multivariate analysis, gender, body mass index (BMI), Child-Pugh classification, extrahepatic metastases, tumor burden, aspartate aminotransferase (AST) and alpha-fetoprotein (AFP) were identified as significant predictors of OS and ECOG-performance status, Child-Pugh classification and extrahepatic metastases were identified as significant predictors of PFS. Among three continuous variables (i.e., BMI, AST and AFP), AFP had the highest TAAT score for the entire cohort. In subgroup analyses, AFP had the highest TAAT score except for Child-Pugh B and female among three continuous variables. In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy.

    Full Text Available PhilDB is an open-source time series database that supports storage of time series datasets that are dynamic; that is, it records updates to existing values in a log as they occur. PhilDB eases loading of data for the user by utilising an intelligent data write method. It preserves existing values during updates and abstracts the update complexity required to achieve logging of data value changes. It implements fast reads to make it practical to select data for analysis. Recent open-source systems have been developed to indefinitely store long-period high-resolution time series data without change logging. Unfortunately, such systems generally require a large initial installation investment before use because they are designed to operate over a cluster of servers to achieve high-performance writing of static data in real time. In essence, they have a ‘big data’ approach to storage and access. Other open-source projects for handling time series data that avoid the ‘big data’ approach are also relatively new and are complex or incomplete. None of these systems gracefully handle revision of existing data while tracking values that change. Unlike ‘big data’ solutions, PhilDB has been designed for single machine deployment on commodity hardware, reducing the barrier to deployment. PhilDB takes a unique approach to meta-data tracking; optional attribute attachment. This facilitates scaling the complexities of storing a wide variety of data. That is, it allows time series data to be loaded as time series instances with minimal initial meta-data, yet additional attributes can be created and attached to differentiate the time series instances when a wider variety of data is needed. PhilDB was written in Python, leveraging existing libraries. While some existing systems come close to meeting the needs PhilDB addresses, none cover all the needs at once. PhilDB was written to fill this gap in existing solutions. This paper explores existing time

    Full Text Available RACIONAL: A hipertensão portal com sua principal complicação, a hemorragia digestiva alta varicosa, são importantes causas de morbimortalidade em cirróticos. A cirurgia de Teixeira-Warren é uma derivação portal seletiva, adotada em doentes Child-Pugh A e B para tratamento da hemorragia varicosa por hipertensão portal não responsiva à terapêutica clínico-endoscópica após o quadro agudo. O índice de congestão portal baseia-se em valores obtidos pela ultra-sonografia Doppler abdominal e encontra-se elevado em pacientes com hipertensão portal. OBJETIVO: Verificar se o índice de congestão portal e o grau de insuficiência hepática (Child-Pugh são fatores preditivos de recidiva hemorrágica após a cirurgia de Teixeira-Warren. MÉTODO: Em estudo longitudinal retrospectivo analisaram-se 62 prontuários de cirróticos operados pela técnica de Teixeira-Warren na Santa Casa de São Paulo. Foram submetidos a avaliação quanto ao índice de congestão portal pré-operatório 36 doentes, e 58 quanto à classe Child-Pugh. Os doentes foram divididos em grupos - com recidiva e ausência de recidiva hemorrágica - sendo analisada a diferença estatística quanto aos valores do índice e Child-Pugh pré-operatórios, relacionando-os à recidiva hemorrágica pós-operatória. RESULTADOS: Dos doentes que apresentaram recidiva hemorrágica, 69% eram Child B e possuíam índice de congestão portal médio de 0,09. Já entre aqueles que não ressangraram, 62% eram Child A e o índice de congestão portal médio foi de 0,076. A diferença foi estatisticamente significante para a classe Child-Pugh, porém, o mesmo não ocorreu para o índice de congestão portal. CONCLUSÃO: O índice de congestão portal no pré-operatório não foi fator preditivo de recidiva hemorrágica em cirróticos submetidos a cirurgia de Teixeira-Warren. Doentes classificados como Child-Pugh B possuem maior chance de recidiva hemorrágica pós-derivação esplenorrenal

    Liver cirrhosis has been associated with portal hypertension as a common complication with subsequent development of esophageal varices (EV).Bleeding due to rupture of esophageal varices (EV) is one of main cause of death in liver cirrhosis, that endoscopy screening is recommended. The aim of work was to determin the of the degree esophageal varices endoscopically in in 60 cirrhotic patients,(32 in Child-Pugh's class A, 16 in Child-Pugh's class B, and 12 in Child-Pugh's class C) who were examined clinically, laboratory , ultrasonography to and comparing them with the determines of the spleen ultrasonography and some biochemical data . Correlation analysis was done to assess this study. Of 60 patients, 20 were admitted to hospital because of acute gastro-intestinal bleeding and 40 without history of gastro-intestinal bleeding. The range age of patients was 30-65 years (average 48.4 ± 8.6 years), 6 (10%) patients with EV grade I, 14(23.4%) patients with grade II and 10 (16.6%) patients with grade III. Twinty patients having esophageal varices of different degrees, had no splenomegaly. A negative correlation was found between spleen diameter and the degree of EV (p < 0.05). The percentage of patients with varices increased with the severty of Liver cirrhosis: 6(18.8) of 32 patients in Child-Pugh class A,14 (87.5%) of 16 in Child-Pugh class B, and 10(83.3%) of 12 in Child-Pugh class C had varices.The degree of EV significantly correlated with Child-Puph score. Patients with varices had lower platelet counts comparison to those without varices (237.259 ± 100.305, 298.424 ± 103.09 respectively; p<0.001), and lower serum albumin comparison to those without varices (1.8 ± 0.92, 2.8 ± 0.83 respectively; p<0.001). The platelet count to spleen diameter ratio (PC/SD) in patients with EV were significantly Rasheid et. al., J. Rad. Res. Appl. Sci., 266 Vol. 6, No. 1B (2013) different from patients without EV (945.84±778.59, 686.26± 546.39 respectively; p<0.001).

    Transjugular intrahepatic portosystemic shunt (TIPS) is used to treat complications of cirrhosis such as variceal bleeding and refractory ascites, but it also bears the risk of liver failure, overt hepatic encephalopathy (HE) and cardiac decompensation. Variceal bleeding may be controlled using...... translocation. Both these processes mediate an impaired immunological and hemodynamic response, thereby facilitating the development of acute-on-chronic liver failure (ACLF) and/or death. Similarly, in patients with refractory ascites, TIPS should be used early in treatment to prevent acute kidney injury (AKI...

    To determine related factors to 5 days re-bleeding and 6 week-mortality of an episode of variceal bleeding in cirrhotic patients. Observational, descriptive, co relational, retrospective study. In this study were included the cirrhotic patients who entered to Hipolito Unanue Hospital, Lima, Peru, between January 2006 and February 2012 with suspicion of variceal bleeding. Were excluded patients who bled from nonvariceal origin, or that did not have the data in clinical history to calculate the Child Pugh score, the Model for terminal diseases of the liver (MELD), or the endoscopic report detailing the bleeding source and the presence of esophageal and/or gastric varices. We include 63 patients, 35 (55.6%) were men. The median of age was of 64 years. 26 of them (41.3%) were Child Pugh C, where as the median of MELD score was 9. The multivariate analysis found that the Child Pugh score was related to 6 weeks-mortality (p=0,003), where as the presence of active bleeding during endoscopy (p=0.012) and the value of creatinine (p=0.012) were related to 5 days re-bleeding. The Child Pugh score was related to 6 weeks-mortality in cirrhotic patients with variceal bleeding. Active bleeding during endoscopy and the value of creatinine were related to 5 days re-bleeding.

    Purpose: The aim of this study was to assess the value of abdominal CT and MRI in determining the severity of cirrhosis secondary to hepatitis compared to Child-Pugh classification. Materials and methods: The study included 23 patients who were clinically and histologically diagnosed with chronic liver disease secondary to viral hepatitis. Each patient underwent dynamic abdominal CT imaging and MRI within the same week. CT and MRI findings were retrospectively reviewed. The same parameters were used from the CT and the MR images for each patient. The parameters included liver volume index (posterior segment of the right lobe, medial and lateral segments of the left lobe), spleen volume index, ascites, portosystemic collaterals, contour irregularities of the liver and confluent fibrosis within the liver. The findings were compared with the patients' Child-Pugh grades. Multiple regression analysis was used for statistical analysis. Results: On MRI, liver volume index (P = 0.0001), and ascites (P = 0.009) were strongly correlated with Child-Pugh grades. With CT, only ascites was correlated with Child-Pugh grades (P = 0.002). Conclusion: This study indicates that liver volume index on MRI, and ascites on CT and MRI are good indicators of clinical severity of cirrhosis secondary to hepatitis. To show the effect of the other parameters, more research is needed with larger patient groups

  14. The role of Dr Isaac Aaron and the Australian Medical Journal in the dissemination of information about etherisation in the 1840s.

    2013-07-01

    Isaac Aaron (1804 to 1877), an ambitious young medical practitioner, arrived in Sydney from Britain in 1838 and was registered by the New South Wales Medical Board the following year. After contributing to the Australian Medical Journal, established in August 1846 by William Baker, he became the editor in December and acquired it in May the following year. Dr Pugh became the most prolific local contributor to the journal but he and the editor had a somewhat 'prickly' relationship. Aaron was very critical of etherisation when the first news arrived in Australia, but Pugh chose Aaron's journal in which to report his initial and subsequent experience with the technique. Aaron repeatedly appealed for experimental evidence and rational decision-making to determine the place of etherisation in medical practice. Unfortunately for Australian medicine, Aaron had to suspend the publication of the journal in October 1847, lacking both time and the support of the profession necessary to maintain it. This created an unanticipated adverse outcome for Dr Pugh.

    To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

    To evaluate the relationship between the location of hepatocellular carcinoma (HCC) and the efficacy of transarterial chemoembolization (TACE). We evaluated 115 patients (127 nodules), excluding recurrent nodules, treated with TACE between January 2011 and June 2014. TACE efficacy was evaluated according to mRECIST. The HCC location coefficient was calculated as the distance from the central portal portion to the HCC center (mm)/liver diameter (mm) on multiplanar reconstruction images rendered (MPR) to visualize bifurcation of the right and left branches of the portal vein and HCC center. The HCC location coefficient was compared between complete response (CR) and non-CR groups in Child-Pugh grade A and B patients. The median location coefficient of HCC among all nodules, the right lobe, and the medial segment was significantly higher in the CR group than in the non-CR group in the Child-Pugh grade A patients (0.82 vs 0.62, P location coefficient of the HCC in the lateral segment between in the CR and in the non-CR groups (0.67 vs 0.65, P > 0.05). On the other hand, in the Child-Pugh grade B patients, the HCC median location coefficient in each lobe and segment was not significantly different between in the CR and in the non-CR groups. Improved TACE efficacy may be obtained for HCC in the peripheral zone of the right lobe and the medial segment in Child-Pugh grade A patients.

    Background: The mesenchymal-epithelial transition factor (MET) receptor is dysregulated in hepatocellular carcinoma (HCC), and tivantinib (ARQ 197) is an oral, selective, MET inhibitor. Methods: This Phase-1b study assessed tivantinib safety as primary objective in patients with previously treated HCC and Child-Pugh A or B liver cirrhosis. Patients received oral tivantinib 360 mg twice daily until disease progression or unacceptable toxicity. Results: Among 21 HCC patients, common drug-related adverse events (AEs) were neutropaenia, anaemia, asthenia, leucopaenia, anorexia, diarrhoea, and fatigue. No drug-related worsening of liver function or performance status occurred, but one Child-Pugh B patient experienced drug-related bilirubin increase. Four patients had drug-related serious AEs, including one neutropaenia-related death. Haematologic toxicities were more frequent than in previous tivantinib studies but were manageable with prompt therapy. Best response was stable disease (median, 5.3 months) in 9 of 16 evaluable patients (56%). Median time to progression was 3.3 months. Conclusion: Tivantinib demonstrated a manageable safety profile and preliminary antitumour activity in patients with HCC and Child-Pugh A or B cirrhosis. PMID:23287988

    Patients with advanced liver disease have an increased risk of complications, compared to healthy patients when they undergo a surgical procedure. This risk is related to the type of surgery, to the type of anesthetic used, and to the severity of the underlying liver disease. Several risk factors for liver disease should be identified prior to a procedure. Those with advanced disease should undergo specific pre-surgical diagnostic tests. The Child Pugh score, and the MELD score, are very useful to establish the surgical risk in individuals with liver disease. The Child-Pugh score is a very useful tool that correlates closely to morbidity and mortality in patients with liver disease. Mortality rates in these patients undergoing major surgery is 10, 30 and 82% for Child-Pugh scores A, B and C respectively. In order to optimize the patient's condition before surgery, a complete evaluation and management of conditions such as jaundice, coagulopathy, ascites, electrolyte abnormalities, renal insufficiency and encephalopathy must be performed. This approach helps to reduce the complication rate in these individuals

    Cytokines are polypeptides that have a wide spectrum of inflammatory, metabolic, hematopoietic and immunologic regulatory properties. The liver represents an important site of synthesis and clearance organ for several cytokines. This study aimed to evaluate serum IL-6 in liver cirrhosis with the type of underlying disease, child pugh group and various clinical and laboratory parameter. This cross-sectional study was at Adam Malik General Hospital and Pirngadi General Hospital from July - December 2016. We examine 75 patients with liver cirrhosis. The exclusion criteria were hepatoma, sepsis and renal impairment. There were 28 (37.3%), 8 (10.6%) and 39 (52%) for HBV-positive; HCV-positive and HBV- HCV negative liver cirrhosis patients, respectively were 14 (18.7 %), 15 (20 %) and 46 (61.3%) for Child- Pugh A, B and C respectively. There was no significant difference value of IL-6 between HBV positive, HCV positive, and HBV-HCV negative group (7.7/6.1/10.9). There was no significant difference value of IL-6 between child pugh A, B, and C group (4.2/11.0/7.9).

    Purpose: The purpose of this study was to assess differences in enhancement effects of liver parenchyma between normal and cirrhotic livers on dynamic, Gd-EOB-DTPA enhanced MRI at 3 T. Materials and methods: 93 patients with normal (n = 54) and cirrhotic liver (n = 39; Child–Pugh class A, n = 18; B, n = 16; C, n = 5) underwent contrast-enhanced MRI with liver specific contrast media at 3 T. T1-weighted volume interpolated breath hold examination (VIBE) sequences with fat suppression were acquired before contrast injection, in the arterial phase (AP), in the late arterial phase (LAP), in the portal venous phase (PVP), and in the hepatobiliary phase (HBP) after 20 min. The relative enhancement (RE) of the signal intensity of the liver parenchyma was calculated for all phases. Results: Mean RE was significantly different among all evaluated groups in the hepatobiliary phase and with increasing severity of liver cirrhosis, a decreasing, but still significant reduction of RE could be shown. Phase depending changes of RE for each group were observed. In case of non-cirrhotic liver or Child–Pugh Score A cirrhosis mean RE showed a significant increase between AP, LAP, PVP and HBP. For Child–Pugh B + C cirrhosis RE increased until PVP, however, there was no change in case of B cirrhosis (p = 0.501) and significantly reduced in case of C cirrhosis (p = 0.043) during HBP. Conclusion: RE of liver parenchyma is negatively affected by increased severity of liver cirrhosis, therefore diagnostic value of HBP could be limited in case of Child Pugh B + C cirrhosis.

    Full Text Available Schistosomiasis mansoni affects the hepatic functional reserve. Clinical treatment with oxamniquine is not 100% effective and there has been found strain of this parasite resistant to this drug. The aims of this investigation were: (1 to examine the presence of residual parasite burden after medical and surgical treatment on adolescents with surgical schistosomiasis mansoni and (2 to assess the effect on the hepatic functional reserve in patients with and without residual infection. Twenty nine children with hepatosplenic schistosomiasis mansoni and bleeding esophageal varices were treated with oxamniquine. They underwent splenectomy, ligature of the left gastric vein and autologous implantation of spleen tissue into the greater omentum. After a mean post-operative follow up of five years they underwent rectal biopsy for schistosomotic egg search. They were divided in patients with and without infection. In 20 patients the submucosal egg search was negative, however, in 9 it was positive. The hepatic functional reserve in the patients without infection was as follows: 17 were Child-Pugh A and 3 Child-Pugh B. In the patients who were still infected 6 were Child-Pugh A and 3 Child-Pugh B. The chi2 analysis of the hepatic functional reserve showed chi2 = 3.19 - p= 0.07. From the results the following conclusion can be drawn: residual infection or reinfection in the follow up period had not interfered with the distribution of the hepatic functional reserve of the patients in this series. However, there was a trend for a decrease of this parameter in patients with residual infection.

    Full Text Available We present some results on the existence and nonexistence of centers for polynomial first order ordinary differential equations with complex coefficients. In particular, we show that binomial differential equations without linear terms do not have complex centers. Classes of polynomial differential equations, with more than two terms, are presented that do not have complex centers. We also study the relation between complex centers and the Pugh problem. An algorithm is described to solve the Pugh problem for equations without complex centers. The method of proof involves phase plane analysis of the polar equations and a local study of periodic solutions.

    Highlights: • The use of MR to classify cirrhosis in different stages is a new interesting field. • We compared liver and spleen T1 mapping, T2 mapping and diffusion-weighted imaging. • MR relaxometry using liver T1 mapping is accurate for the diagnosis of cirrhosis. • Liver T1 mapping shows that values increase with the severity of cirrhosis. • Diffusion-weighted imaging is less accurate than T1 mapping while T2 mapping is not reliable. - Abstract: Background: MR relaxometry has been extensively studied in the field of cardiac diseases, but its contribution to liver imaging is unclear. We aimed to compare liver and spleen T1 mapping, T2 mapping, and diffusion-weighted MR imaging (DWI) for assessing the diagnosis and severity of cirrhosis. Methods: We prospectively included 129 patients with normal (n = 40) and cirrhotic livers (n = 89) from May to September 2014. Non-enhanced liver T1 mapping, splenic T2 mapping, and liver and splenic DWI were measured and compared for assessing cirrhosis severity using Child-Pugh score, MELD score, and presence or not of large esophageal varices (EVs) and liver stiffness measurements using Fibroscan{sup ®} as reference. Results: Liver T1 mapping was the only variable demonstrating significant differences between normal patients (500 ± 79 ms), Child-Pugh A patients (574 ± 84 ms) and Child-Pugh B/C patients (690 ± 147 ms; all p-values <0.00001). Liver T1 mapping had a significant correlation with Child-Pugh score (Pearson's correlation coefficient of 0.46), MEDL score (0.30), and liver stiffness measurement (0.52). Areas under the receiver operating characteristic curves of liver T1 mapping for the diagnosis of cirrhosis (O.85; 95% confidence intervals (CI), 0.77–0.91), Child-Pugh B/C cirrhosis (0.87; 95%CI, 0.76–0.93), and large EVs (0.75; 95%CI, 0.63–0.83) were greater than that of spleen T2 mapping, liver and spleen DWI (all p-values < 0.01). Conclusion: Liver T1 mapping is a promising new diagnostic

Results: Liver T1 mapping was the only variable demonstrating significant differences between normal patients (500 ± 79 ms), Child-Pugh A patients (574 ± 84 ms) and Child-Pugh B/C patients (690 ± 147 ms; all p-values <0.00001). Liver T1 mapping had a significant correlation with Child-Pugh score (Pearson's correlation coefficient of 0.46), MEDL score (0.30), and liver stiffness measurement (0.52). Areas under the receiver operating characteristic curves of liver T1 mapping for the diagnosis of cirrhosis (O.85; 95% confidence intervals (CI), 0.77–0.91), Child-Pugh B/C cirrhosis (0.87; 95%CI, 0.76–0.93), and large EVs (0.75; 95%CI, 0.63–0.83) were greater than that of spleen T2 mapping, liver and spleen DWI (all p-values < 0.01). Conclusion: Liver T1 mapping is a promising new diagnostic tool for

    To investigate the impact of low skeletal muscle mass (LSMM) on survival as compared with protein-energy malnutrition (PEM) in patients with liver cirrhosis (LC). A total of 206 individuals with LC were analyzed. We retrospectively examined the impact of LSMM, as defined by psoas muscle mass at the third lumber on computed tomography, on survival as compared with PEM. In terms of comparison of the effects of LSMM and PEM on survival, we used time-dependent receiver operating characteristics (ROC) analysis. Our study cohort included 115 men and 91 women with a median age of 67 years. There were 140 patients with Child-Pugh A, 62 with Child-Pugh B, and 4 with Child-Pugh C. A total of 117 patients (56.8%) had LSMM and 52 patients (25.2%) had PEM. The proportion of PEM in patients with LSMM (31.62%, 37/117) was significantly higher than in patients without LSMM (16.85%, 15/89) (P = 0.0229). In the multivariate analysis for the entire cohort, the presence of hepatocellular carcinoma, lower body mass index, presence of LSMM, lower triglyceride value, poorer renal function, and higher des-γ-carboxy prothrombin value were found to be significant adverse predictors linked to overall survival, while presence of PEM tended to be significant. In the time-dependent ROC analysis, all area under the ROCs for survival in LSMM at each time point were higher than those in PEM except for Child-Pugh B patients. In this comparison of LSMM and PEM on clinical outcomes in LC patients, it was shown that LSMM may have stronger prognostic impact than PEM. © 2016 The Japan Society of Hepatology.

    Full Text Available In this study, 44 patients with liver cirrhosis were investigated for hemostatic parameters. Patients with spontaneous bacterial peritonitis, hepatocellular carcinoma, hepatorenal syndrome and cholestatic liver diseases were excluded. Patients were classified by Child-Pugh criterion and according to this 4 patients were in Class A, 20 in Class B and 20 in C. Regarding to these results, it was aimed to investigate the haematological disturbances in liver cirrhotic patients.In the result there was a correlation between activated partial thromboplastin time, serum iron, ferritin, transferrin, haptoglobin and Child-Pugh classification. Besides there was no correlation between prothrombin time, factor 8 and 9, protein C and S, anti-thrombin 3, fibrinogen, fibrin degradation products, serum iron binding capacity, hemoglobin, leukocyte, mean corpuscular volume and Child-Pugh classification.There were significant difference, in terms of AST, ferritin, haptoglobulin, sex and presence of ascites between groups (p0.05. In the summary, we have found correlation between hemostatic abnormalities and disease activity and clinical prognosis in patients with liver cirrhosis which is important in the management of these patients. This is also important for identification of liver transplant candidiates earlier.

    Sorafenib significantly improves survival in patients with advanced hepatocellular carcinoma (HCC). This phase IV study assessed sorafenib efficacy/safety in Taiwanese patients with advanced HCC and Child-Pugh A status. All patients received 400 mg sorafenib BID. Safety, efficacy, sorafenib pharmacokinetics, and Child-Pugh progression were evaluated. A hand-foot skin reaction (HFSR) prevention substudy assessed HFSR incidence and grade/severity and time to HFSR in 29 and 34 patients randomized to corticosteroid and noncorticosteroid ointments, respectively, and in 88 nonrandomized patients. The 151 patients included 120 (80%) male patients and 81 (54%) with stage IV disease. Mean sorafenib dose was 626 mg/day, and median treatment duration was 4.2 months. Median overall survival (OS), progression-free survival, and time to progression (TTP) were 8.6, 2.7, and 3.8 months, respectively. Disease control and response rates (partial responses only) were 48 and 6.6%, respectively. Median TTP from Child-Pugh A to B/C was 88 days. Drug-related adverse events (AEs) occurred in 89.4% of patients; none were new or unexpected. The most frequent grade ≥3 drug-related, treatment-emergent AEs were HFSR (13.2%), diarrhea (11.9%), and hypertension (6.6%). Corticosteroid ointment tended to reduce the severity and incidence of all HFSR-associated parameters. Pharmacokinetic exposure was unaltered by Child-Pugh progression. The final pharmacokinetic model predicted 13.1 and 33.8% reductions in sorafenib exposure over 6 and 12 months, respectively. There was a trend of longer OS and TTP in Taiwanese patients with advanced HCC compared with patients with advanced HCC in the Asia-Pacific trial. Sorafenib exposure did not correlate with liver function. Reduced pharmacokinetic exposure over time was unrelated to reduced or interrupted dosing.

    To investigate the clinical and dose–volumetric parameters that predict the risk of radiation-induced liver disease (RILD) for patients with small, unresectable hepatocellular carcinoma (HCC) treated with stereotactic body radiotherapy (SBRT). Between March 2007 and December 2009, 92 patients with HCC treated with SBRT were reviewed for RILD within 3 months of completing treatment. RILD was evaluated according to the Common Terminology Criteria for Adverse Events, version 3.0. A dose of 10–20 Gy (median, 15 Gy) per fraction was given over 3–4 consecutive days for a total dose of 30–60 Gy (median, 45 Gy). The following clinical and dose–volumetric parameters were examined: age, gender, Child-Pugh class, presence of hepatitis B virus, gross tumor volume, normal liver volume, radiation dose, fraction size, mean dose to the normal liver, and normal liver volumes receiving from < 5 Gy to < 60 Gy (in increments of 5 Gy). Seventeen (18.5%) of the 92 patients developed grade 2 or worse RILD after SBRT (49 patients in grade 1, 11 in grade 2, and 6 in ≥ grade 3). On univariate analysis, Child-Pugh class was identified as a significant clinical parameter, while normal liver volume and normal liver volumes receiving from < 15 Gy to < 60 Gy were the significant dose–volumetric parameters. Upon multivariate analysis, only Child-Pugh class was a significant parameter for predicting grade 2 or worse RILD. The Child-Pugh B cirrhosis was found to have a significantly greater susceptibility to the development of grade 2 or worse RILD after SBRT in patients with small, unresectable HCC. Additional efforts aimed at testing other models to predict the risk of RILD in a large series of HCC patients treated with SBRT are needed

    The ART score (a point score for the assessment of retreatment with transarterial chemoembolization, TACE) has been recently developed in Austria to differentiate patients who may benefit from multiple sessions of TACE for hepatocellular carcinoma (HCC) treatment. The primary aim of the study was to test the validity of the ART score in an Italian study cohort. The secondary aims were to evaluate overall survival (OS) and clinical determinants of improved survival in patients treated with multiple TACE sessions. The ART score and the clinical outcome of 51 consecutive patients with HCC submitted to multiple TACE sessions from April 2002 to December 2009 were retrospectively analyzed. Median OS was 26.0 months (95% confidence interval 18.4-33.6) with 1-, 3- and 5-year survival rates of 75, 33 and 11%, respectively). Thirty-three patients had an ART score of 0-1.5 and in 18 it was ≥2.5, but in our patient series, the ART score was not found to be a predictor of survival (p = 0.173). At univariate analysis, tumor extent (uni- vs. bilobar: 34.0 vs. 9.0 months; p < 0.001), Child-Pugh score before the second TACE (A vs. B7 vs. B8-9: 26.0 vs. 16.0 vs. 5.0 months; p = 0.005) and Child-Pugh score increase between the first and second TACE (absent vs. + 1 point vs. + ≥2 points: 27.0 vs. 4.0 vs. 5.0 months; p < 0.001) were statistically related with survival. At multivariate analysis, only Child-Pugh score increase remained a significant predictor of worse survival (p = 0.001, hazard rate = 11.6). The ART score was not found to work as an objective tool to guide TACE retreatment in our Italian patient series, only the Child-Pugh score increase was an independent predictor of a shorter survival.

    Full Text Available CONTEXT: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identification of the best nutritional assessment method. OBJECTIVE: To identify a method that provides a safe and effective nutritional diagnosis. METHODS: Cross-sectional study with 129 cirrhotic patients. Anthropometric measurements, subjective global assessment, hand grip strength and bioelectrical impedance. RESULTS: Through phase angle of bioelectrical impedance analysis (BIA method, significant associations with Child-Pugh (P = 0.008, age group and gender were observed. The ROC (receiver operator characteristic curve was generated to determine the best cutoff point of the phase angle of cirrhotic patients, serving as one of the reference parameters for the nutritional assessment with bioimpedance in this study, considering the classification through Child-Pugh score as the reference standard for the clinical conditions of patients with cirrhosis. CONCLUSIONS: The assessment through bioelectrical impedance presented a statistically significant correlation with Child-Pugh score. The identification of phase angle of 5.44º is the new parameter suggested for the classification of the nutritional conditions of cirrhotic patients.

    Purpose: To evaluate the association between gadoxetic-acid-enhanced magnetic resonance (MR) imaging measurements and laboratory and clinical biomarkers of liver function and fibrosis. Materials and methods: One hundred thirty nine consecutive patients with suspected liver disease or liver tumor underwent gadoxetic-acid-enhanced MR imaging. MR imaging measurements during the hepatobiliary phase included biliary tract structure-to-muscle signal intensity ratio (SIR). These measurements were compared with Child-Pugh classification, end-stage liver disease (MELD) score, and aspartate aminotransferase-to-platelet ratio index (APRI). Results: The SIRs of cystic duct and common bile duct were significantly correlated with Child-Pugh classification (P = 0.012 for cystic duct and P < 0.0001 for common bile duct), MELD score (P = 0.0016 and P = 0.0033), and APRI (P = 0.0022 and P = 0.0015). The sensitivity, specificity, and area under the receiver-operating-characteristic curve were: (74%, 88%, 0.86) with the SIR of common bile duct for the detection of patients with Child-Pugh class B or C; (100%, 87%, 0.94) with the SIR of cystic duct for MELD score (>10); (65%, 76%, 0.70) with the SIR of common bile duct for APRI (>1.5). Conclusion: Gadoxetic-acid contrast enhancement of cystic duct and common bile duct could be used as biomarkers to assess liver function.

    Severe infections and muscle wasting are both associated to poor outcome in cirrhosis. A possible synergic effect of these two entities in cirrhotic patients has not been previously investigated. We aimed at analysing if a low muscle mass may deteriorate the outcome of cirrhotic patients with sepsis. Consecutive cirrhotic patients hospitalized for sepsis were enrolled in the study. Patients were classified for the severity of liver impairment (Child-Pugh class) and for the presence of "low muscle mass" (mid-arm muscle circumferencelow muscle mass. In patients with and without low muscle mass, severity of liver disease and characteristics of infections were similar. Mortality tended to be higher in patients with low muscle mass (47% vs 26%, P = .06). A multivariate analysis selected low muscle mass (P low muscle mass compared with those without (50% vs 16%; P = .01). The mortality rate and the incidence of complications in malnourished patients classified in Child-Pugh A-B were similar to those Child-Pugh C. Low muscle mass worsen prognosis in cirrhotic patients with severe infections. This is particularly evident in patients with Child A-B cirrhosis in whom the coexistence of low muscle mass and sepsis caused a negative impact on mortality similar to that observable in all Child C patients with sepsis. © 2018 John Wiley & Sons A/S.

    Full Text Available Objective. To examine Nogo-B in liver tissues and plasma of patients with liver cirrhosis and associate them with various clinical parameters. Materials and Methods. Nogo-B protein expression was examined by immunohistochemistry in 24 human fibrotic/cirrhotic liver specimens and 10 healthy controls. We determined plasma Nogo-B levels by enzyme-linked immunosorbent assay in 301 patients with liver cirrhosis and 153 healthy controls, and then analyzed various clinical parameters. Results. Nogo-B was mainly expressed in nonparenchymal cells in the liver and was marked increased in liver with significant fibrosis/cirrhosis compared to controls. Moreover, Metavir F4 showed a higher level of expression than F2. Plasma Nogo-B levels were significantly higher in cirrhotic patients than in healthy controls and were the highest in Child-Pugh class C patients. Plasma Nogo-B levels were positively correlated with Child-Pugh scores. However, there was no relationship between plasma Nogo-B levels and etiology of liver diseases, ALT, AST, platelet counts, and the severity of esophagogastric varices. Conclusions. Nogo-B is mainly expressed in hepatic nonparenchymal cells and is present in plasma. Abnormally high plasma levels of Nogo-B are associated with hepatic cirrhosis and Child-Pugh score, but not correlated with the grade of liver inflammation or portal hypertension. Plasma Nogo-B may be a novel surrogate marker to reflect liver function reserve.

    Malnutrition is prevalent in patients with advanced liver disease (LD) related to multifactorial causes. Fluid retention can underestimate the nutritional status based on anthropometric measures. We evaluated nutritional indicators and body composition (BC) in patients with liver cirrhosis and correlated them with LD severity. Forty three patients with LD enrolled for liver transplantation were evaluated by Anthropometric measures, subjective evaluation (Global Assessment of Nutritional Status - SGA) and biochemical indicators. Single-frequency electrical bioimpedance (SFE-BIA) was used to evaluate body composition (BC). It measured resistance (R), reactance (Xc) and the phase angle (PA). LD severity was estimated by Child-Pugh and Meld criteria (Model for End-Stage Liver Disease). Child-Pugh index between patients was 7.11 ± 1.70 and Meld was 12.23 ± 4.22. Arm Circumference, Arm Muscle Circumference and Arm Muscle Area, SGA, hemoglobin, hematocrit and albumin showed better correlation with disease severity. Xc and PA showed correlation both with Meld and Child-Pugh score when BC were evaluated. PA was depleted in 55.8% of the patients. Diagnosis of malnutrition varied according to the method. Global assessment of nutritional status showed better correlation with disease severity than with objective methods. Single-frequency electrical bioimpedance for body composition analysis in cirrhotic patients must be cautiously used; however, primary vectors seems to be valid and promising in clinical practice.

    Rectal varices occur in 44.5 % of patients with ectopic varices caused by portal hypertension, and 48.6 % of these patients are untreated and followed by observation. However, bleeding occurs in 38 % and shock leading to death in 5 % of such patients. Two patients, an 80-year-old woman undergoing treatment for primary biliary cirrhosis (Child-Pugh class A) and a 63-year-old man with class C hepatic cirrhosis (Child-Pugh class A), in whom balloon-occluded antegrade transvenous sclerotherapy was performed to treat rectal varices are reported. A catheter was inserted by directly puncturing the rectal vein percutaneously through the greater sciatic foramen under computed tomographic fluoroscopy guidance. In both cases, the rectal varices were successfully treated without any significant complications, with no bleeding from rectal varices after embolization.

    The objective of our work was to evaluate the long-term results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in patients with liver cirrhosis. A total of 184 cirrhotic patients with HCC underwent PEI as the only anticancer treatment over an 8-year period. Patients were followed after therapy by means of clinical examinations, laboratory tests, and US and CT studies performed at regular time intervals. Survival rates were determined according to the Kaplan-Meier method. The overall survival was 67% at 3 years, 41% at 5 years, and 19% at 7 years. The 3-, 5-, and 7-year survival rates of patients with single HCC≤3 cm (78, 54, and 28%, respectively) were significantly higher (p<0.01) than those of patients with single HCC of 3.1-5 cm (61, 32, and 16, respectively) or multiple HCCs (51, 21, and 0%, respectively). Survival of Child-Pugh A patients (79% at 3 years, 53% at 5 years, and 32% at 7 years) was significantly longer (p<0.01) than that of Child-Pugh B patients (50% at 3 years, 28% at 5 years, and 8% at 7 years). A selected group of 70 patients with Child-Pugh A cirrhosis and single HCC≤3 cm had a 7-year survival of 42%. Long-term survival of cirrhotic patients with HCC treated with PEI is comparable to that reported in published series of matched patients submitted to surgical resection. (orig.)

    Cerebral blood flow autoregulation is lost in patients with severe liver cirrhosis. The cause of this is unknown. We determined whether autonomic dysfunction was related to impaired cerebral autoregulation in patients with cirrhosis. Fourteen patients with liver cirrhosis and 11 healthy volunteers...... were recruited. Autonomic function was assessed in response to deep breathing, head-up tilt and during 24-h Holter monitoring. Cerebral autoregulation was assessed by determining the change in mean cerebral blood flow velocity (MCAVm, transcranial Doppler) during an increase in blood pressure induced...... by norepinephrine infusion (NE). The severity of liver disease was assessed using the Child-Pugh scale (class A, mild; class B, moderate; class C, severe liver dysfunction).NE increased blood pressure similarly in the controls (27 (24-32) mmHg) and patients with the most severe liver cirrhosis (Child-Pugh C, 31 (26...

    Full Text Available Cirurgias realizadas em pacientes com reserva funcional hepática reduzida podem apresentar altos índices de morbi-mortalidade. Uma triagem pré-operatória ideal visa detectar a doença hepática pré-existente, sem necessidade de métodos invasivos. A história clínica e o exame físico fornecem pistas importantes. A quantificação da função hepática de rotina não é necessária, a menos que exista alguma alteração na história ou exame físico. A doença hepática causa diversos efeitos na cirurgia e anestesia. A indução anestésica, hemorragias, hipoxemia, hipotensão, drogas vasoativas e até a posição do paciente na mesa cirúrgica podem provocar diminuição na oxigenação e maior risco de disfunção hepática no intra e pós-operatório. A cirurgia de emergência é um grande preditor de mau prognóstico assim como a sepse e as reoperações. Para uma correta preparação pré-operatória, deve-se levar em consideração a natureza da doença hepática, sua gravidade e o tipo de cirurgia a ser realizada. Algumas ações devem ser tomadas no pré-operatório para diminuir as chances de complicações em pacientes portadores de hepatopatias submetidos a procedimentos cirúrgicos. O combate à coagulopatia, encefalopatia, ascite, disfunção renal e pulmonar, peritonite bacteriana espontânea e varizes de esôfago deve ser precoce e agressivo. Doentes Child-Pugh C e MELD > 15 não devem ser submetidos a cirurgias eletivas. Doentes Child-Pugh B e com MELD de 10 a 15 podem ser submetidos a pequenos procedimentos cirúrgicos em caso de extrema necessidade e com cautela. Finalmente doentes Child-Pugh A e MELD Patients with impaired hepatic functional reserve when submitted to surgeries may have high rates of morbidity and mortality. Pre-existing liver disease should be detected without need for invasive METHODS. Clinical history and physical examination provide important clues. Laboratory liver function is not necessary unless

    To compare the enhancement features of hepatic parenchyma between cirrhotic and normal liver, using Gd-BOPTA-enhanced delayed MR imaging. The 60 patients (35 with cirrhotic and 25 with normal liver) included in our study underwent Gd-BOPTA-enhanced MR imaging using a 1.5T system with a phase-array multicoil. In all cases, T1-weighted in-phase and opposed-phase gradient-echo MR imaging was performed before and 60 minutes after intravenous administration of a bolus of Gd-BOPTA. All images were quantitatively analysed by comparing the signal-to-noise ratio (SNR) and signal enhancement (SE) of cirrhotic and normal liver before and after contrast enhancement, and in cirrhotic patients, SNR and SE were also compared in terms of the Child-Pugh classification. For qualitative analysis, the hepatic enhancement patterns of cirrhotic and normal liver were classified as homogeneous or heterogeneous according to the consensual findings of two radiologists. At contrast-enhanced imaging, both cirrhotic (p<0.001) and normal liver (p<0.001) showed substantially increased SNR relative to unenhanced images, and the SNR of cirrhotic liver was significantly lower than that of normal livers at both in-phase (p<0.001) and opposed-phase (p<0.001) imaging. The SE of cirrhotic liver was significantly lower than that of normal liver (in-phase:p=0.002; opposed phase:p=0.011). Both Child-Pugh class A (p<0.001) and B (p<0.001) cirrhotic liver showed a substantial increase in SNR at contrast-enhanced imaging relative to unenhanced imaging and the SNR of Child-Pugh class A was significantly higher than that of Child-Pugh class B at both in-phase (p<0.001) and opposed-phase (p=0.022) imaging. In addition, the SE of class A was significantly higher than that of class B at in-phase imaging (p=0.004). Cirrhotic liver showed heterogeneous enhancement in 20 of 35 patients (57%), whereas normal liver showed homogeneous enhancement in all patients. At Gd-BOPTA-enhanced delayed MR imaging, cirrhotic liver

    Introduction: At least 40% of survivors of biliary atresia have progressive cirrhosis even after undergoing Kasai operation. The values of hepatic apparent diffusion coefficient and apparent-diffusion-coefficient-related indices were applied to biliary atresia patients and correlated with cirrhotic severity scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh systems. Materials and methods: Thirty-three biliary atresia patents (mean = 1140, 61–4314 days of age) received magnetic resonance image examinations due to complications of biliary atresia from April 2008 to August 2009. Two non-breath-hold diffusion weighted imaging sequences were performed with motion-probing gradients in three directions with two b values: 0/100 and 0/500 s/mm 2 ; 1000 ms/61.1 ms, time to repeat/time to echo; number of excitation, 1.0; 8 mm section thickness; 40 cm × 40 cm field of view; 128 × 256 matrix in all biliary atresia patients and 18 control subjects. We used the Spearman rank correlation test to analyze the relationship among the scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte and Child-Pugh scores and right hepatic apparent diffusion coefficients, apparent diffusion coefficient using b factor of 500-albumin product and alanine transaminase/apparent diffusion coefficient with b factor of 500 ratio. Results: The right hepatic apparent diffusion coefficient using b factor of 100, apparent diffusion coefficient with b factor of 500 and product of apparent diffusion coefficient with b factor of 500-albumin level were significantly negatively correlated (p ≤ 0.0125) with model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh scores of biliary atresia patients. The ratio of alanine transaminase level/right hepatic apparent diffusion coefficient with b factor of 500 was also significantly (p ≤ 0

    Objective: To evaluate the effect of transcatheter arterial chemoembolization (TACE) plus partial spleen embolization (PSE) on the liver function in patients with hepatocellular carcinoma (HCC). Methods: 85 patients with HCC complicated with portal hypertension and hypersplenism, including group A 45 patients with treatment of TACE plus PSE and group B 40 patients with single TACE were observed. The liver function was evaluated with Child Pugh scores before and after the procedure. Results: There was no difference in the levels of TBIL, ALT, ALB and Child Pugh scores between groups A and B (P>0.05) but remarkable change after therapy was shown at one week later (P<0.05, P<0.01). The liver function tests showed remarkable improvement in the TACE plus PSE group. Conclusion: TACE combined with PSE is a safe and effective procedure for patients with HCC associated with liver cirrhosis, portal hypertension and hypersplenism. (authors)

    Traditional strengthening ways, such as strain, precipitation, and solid-solution, come into effect by pinning the motion of dislocation. Here, through first-principles calculations we report on an extra-electron induced covalent strengthening mechanism, which alters chemical bonding upon the introduction of extra-valence electrons in the matrix of parent materials. It is responsible for the brittle and high-strength properties of Al(12)W-type compounds featured by the typical fivefold icosahedral cages, which are common for quasicrystals and bulk metallic glasses (BMGs). In combination with this mechanism, we generalize ductile-to-brittle criterion in a universal hyperbolic form by integrating the classical Pettifor's Cauchy pressure with Pugh's modulus ratio for a wide variety of materials with cubic lattices. This study provides compelling evidence to correlate Pugh's modulus ratio with hardness of materials and may have implication for understanding the intrinsic brittleness of quasicrystals and BMGs.

    The purpose of current study is to evaluate the response of the patients with portal vein thrombosis (PVT) or hepatic vein thrombosis (HVT) in hepatocellular carcinoma (HCC) treated with three-dimensional conformal radiation therapy (3D-CRT). In addition, survival of patients and potential prognostic factors of the survival was evaluated. Forty-seven patients with PVT or HVT in HCC, referred to our department for radiotherapy, were retrospectively reviewed. For 3D-CRT plans, a gross tumor volume (GTV) was defined as a hypodense filling defect area in the portal vein (PV) or hepatic vein (HV). Survival of patients, and response to radiation therapy (RT) were analyzed. Potential prognostic factors for survival and response to RT were evaluated. The median survival time of 47 patients was 8 months, with 1-year survival rate of 15% and response rate of 40%. Changes in Child-Pugh score, response to RT, Eastern cooperative oncology group performance status (ECOG PS), hepatitis C antibody (HCVAb) positivity, and additional post RT treatment were statistically significant prognostic factors for survival in univariate analysis (p = 0.000, p = 0.018, p = 0.000, p = 0.013, and p = 0.047, respectively). Of these factors, changes in Child-Pugh score, and response to RT were significant for patients' prognosis in multivariate analysis (p = 0.001 and p = 0.035, respectively). RT could constitute a reasonable treatment option for patients with PVT or HVT in HCC with acceptable toxicity. Changes in Child-Pugh score, and response to RT were statistically significant factors of survival of patients.

    Hepatitis B virus (HBV) infection remains a major health problem and HBV-related-decompensated cirrhosis (HBV-DC) usually leads to a poor prognosis. Our aim was to determine the utility of inflammatory biomarkers in predicting mortality of HBV-DC. A total of 329 HBV-DC patients were enrolled. Survival estimates for the entire study population were generated using the Kaplan-Meier method. The prognostic values for model for end-stage liver disease (MELD) score, Child-Pugh score, and inflammatory biomarkers neutrophil/lymphocyte ratio, C-reactive protein-to-albumin ratio (CAR), and lymphocyte-to-monocyte ratio (LMR) for HBV-DC were compared using time-dependent receiver operating characteristic curves and time-dependent decision curves. The survival time was 23.1±15.8 months. Multivariate analysis identified age, CAR, LMR, and platelet count as prognostic independent risk factors. Kaplan-Meier analysis indicated that CAR of at least 1.0 (hazard ratio, 7.19; 95% confidence interval, 4.69-11.03), and LMR less than 1.9 (hazard ratio, 2.40; 95% confidence interval, 1.69-3.41) were independently associated with mortality of HBV-DC. The time-dependent receiver operating characteristic indicated that CAR showed the best performance in predicting mortality of HBV-DC compared with LMR, MELD score, and Child-Pugh score. The results were also confirmed by time-dependent decision curves. CAR and LMR were associated with the prognosis of HBV-DC. CAR was superior to LMR, MELD score, and Child-Pugh score in HBV-DC mortality prediction.

    Full Text Available ABSTRACT Background Patients with liver disease often present protein-energy malnutrition. The assessment of food intake is very important in the investigation regarding the "health-disease" process. Objective To assess dietary intake of cirrhotic patients through food record during 3 days, correlating it with the nutritional status of the patient and the stage of the disease. Methods Cirrhotic outpatients from the Santa Casa de Misericórdia Hospital, RS, Brazil, were assessed. Nutritional assessment was performed by anthropometry; non-dominating handgrip strength; adductor pollicis muscle thickness; phase angle by bioelectrical impedance analysis; and Subjective Global Assessment. For analysis of food consumption we used the food records of 3 days using scales for weighing of all foods. Results We evaluated 25 (68% patients, in which there was a prevalence of cirrhosis by hepatitis C virus. The upper arm circumference, handgrip strength and phase angle by bioelectrical impedance analysis diagnosed 56% of malnourished. Phase angle by bioelectrical impedance analysis and upper arm circumference were associated with Child-Pugh score (P<0.05. The average consumption of calories, carbohydrates, proteins and lipids were within the recommended. However, sodium was above the recommendations, 106±57.2 mEq, and was inversely associated with Child-Pugh score (rs=-0.410; P=0.042. Conclusion Food intake did not have a significant difference between the Child-Pugh scores and nutritional status. In addition, food intake did not vary neither according to the stage of the disease, nor to the nutritional assessment, by the phase angle by bioelectrical impedance analysis.

    In 1946 Philip (Phil) Russell Wallace joined the Mathematics Department of McGill University as an Associate Professor of Applied Mathematics, apparently because A. H. S. Gillson, Dean of Arts and Science, wanted theoretical physicists to be in the Mathematics Department. He came with the dream of creating a theoretical physics group at McGill. By the spring of 1949, Phil was authorized to recruit two junior faculty in Mathematics. He hired Theodore (Ted) F. Morris from U. Toronto, who joined in September 1949, and me, who came in January 1950. The group had begun. Phil Wallace was born in Toronto in 1915 and grew up there. He entered the University of Toronto in 1933, earned a B.A. in mathematics in 1937, a M.A. in 1938, and a Ph.D. in applied mathematics in 1940 under Leopold Infeld. His Ph.D. thesis in general relativity was entitled 'On the relativistic equations of motion in electromagnetic theory.' In 1940 World War II had engulfed Europe and was having its effect on Canada, but the US was still at peace. L. J. Synge, Head of the Applied Mathematics Department at Toronto, told Wallace that people such as he would be needed in war work, but things were not ready quite yet. Hold yourself ready. Phil took a two-year position as lecturer in mathematics at the University of Cincinnati (1940-42); in the fall of 1942 he became a lecturer in mathematics at M.I.T. It was from there that he was recruited by Synge to join the war effort from 1943 to 1946 at N.R.C.'s Montreal Laboratory, the genesis of the Canadian Atomic Energy Project. Phil has described those heady wartime years in these pages. Much of the effort of the theoretical physicists was on nuclear reactor theory and the properties of relevant materials, such as graphite, under long and intense neutron bombardment. In late 1945 Phil was sent for four months to Bristol to learn about the properties of graphite from the esteemed N. F. Mott. This exposure led Phil to a life-long interest in graphite and in

    Density functional theory, density functional perturbation theory, and the Debye model have been used to investigate the structural, elastic, sound velocity, and thermodynamic properties of AlN with cubic rock-salt structure under high pressure, yielding the equilibrium structural parameters, equation of state, and elastic constants of this interesting material. The isotropic shear modulus, Pugh ratio, and Poisson's ratio were also investigated carefully. In addition, the longitudinal, transverse, and average elastic wave velocities, phonon contribution to the thermal conductivity, and interesting thermodynamic properties were predicted and analyzed in detail. The results demonstrate that the behavior of the elastic wave velocities under increasing hydrostatic pressure explains the hardening of the corresponding phonons. Based on the elastic stability criteria under pressure, it is found that AlN with cubic rock-salt structure is mechanically stable, even at pressures up to 100 GPa. Analysis of the Pugh ratio and Poisson's ratio revealed that AlN with cubic rock-salt structure behaves in brittle manner.

    Transcatheter arterial chemoembolization (TACE) offers a survival benefit to patients with intermediate hepatocellular carcinoma (HCC). A widely accepted TACE regimen includes administration of doxorubicin-oil emulsion followed by gelatine sponge-conventional TACE. Recently, a drug-eluting bead (DC Bead) has been developed to enhance tumor drug delivery and reduce systemic availability. This randomized trial compares conventional TACE (cTACE) with TACE with DC Bead for the treatment of cirrhotic patients with HCC. Two hundred twelve patients with Child-Pugh A/B cirrhosis and large and/or multinodular, unresectable, N0, M0 HCCs were randomized to receive TACE with DC Bead loaded with doxorubicin or cTACE with doxorubicin. Randomization was stratified according to Child-Pugh status (A/B), performance status (ECOG 0/1), bilobar disease (yes/no), and prior curative treatment (yes/no). The primary endpoint was tumor response (EASL) at 6 months following independent, blinded review of MRI studies. The drug-eluting bead group showed higher rates of complete response, objective response, and disease control compared with the cTACE group (27% vs. 22%, 52% vs. 44%, and 63% vs. 52%, respectively). The hypothesis of superiority was not met (one-sided P = 0.11). However, patients with Child-Pugh B, ECOG 1, bilobar disease, and recurrent disease showed a significant increase in objective response (P = 0.038) compared to cTACE. DC Bead was associated with improved tolerability, with a significant reduction in serious liver toxicity (P < 0.001) and a significantly lower rate of doxorubicin-related side effects (P = 0.0001). TACE with DC Bead and doxorubicin is safe and effective in the treatment of HCC and offers a benefit to patients with more advanced disease.

    Full Text Available Background: In recent times, there are reports of adrenal dysfunction in whole spectrum of liver disease. Adrenal insufficiency (AI has been shown to correlate with progression of liver disease. Hence this study was conducted to assess adrenal function in subjects with acute liver disease (ALD, chronic liver disease (CLD and post liver transplantation (LT. Material and Methods: This study included 25 healthy controls, 25 patients of ALD, 20 subjects of CLD with Child-Pugh stage A (CLD-1 and 30 with Child-Pugh stage B or C (CLD-2, and 10 subjects with LT. All subjects were assessed clinically, biochemically and for adrenal functions. Results: AI was present in 9 (34.6% patients with ALD, 20 (40% patients with CLD and 4 (40% in subjects with LT. AI was more common in CLD-2 (18 patients - 60% than CLD-1 (2 patients - 10%. All patients with chronic liver disease had significantly lower basal cortisol (8.8±4.8, P=0.01, stimulated cortisol (18.2±6.3, P <0.00001 and incremental cortisol (9.4±4.6, P <0.00001 as compared to controls. There was increase in percentage of subjects with adrenal dysfunction with progression of liver disease as assessed by Child-Pugh staging. AI was predicted by lower levels of serum protein, serum albumin, total cholesterol and HDL cholesterol and higher levels of serum bilirubin and INR. Adrenal functions showed recovery following liver transplantation. Conclusions: AI forms important part of spectrum of acute and chronic liver disease. Deterioration of synthetic functions of liver disease predicts presence of AI, and these patients should be evaluated for adrenal dysfunction periodically.

    Liver resection (LR) and transplantation are the most reliable treatments for hepatocellular carcinoma (HCC). Aim was to compare different guidelines regarding indication for resection and transplantation because of HCC with and without underlying cirrhosis. We compared the following guidelines published after 1 January 2010: American (American Association for the Study of Liver Diseases (AASLD)), Spanish (Sociedad Espanola de Oncologia Medica (SEOM)), European (European Association for the study of liver-European Organization for Research and Treatment of Cancer (EASL-EORTC) and European Society for Medical Oncology-European Society of Digestive Oncology (ESMO-ESDO)), Asian (Asian Pacific Association for the Study of Liver (APASL)), Japanese (Japan Society of Hepatology (JSH)), Italian (Associazione Italiana Oncologia Medica (AIOM)) and German (S3) guidelines. All guidelines recommend resection as therapy of choice in healthy liver. Guidelines based on the Barcelona Clinic Liver Cancer staging system recommend resection for single HCCguidelines recommend LR for patients with Child-Pugh A/B with HCC without tumour size restriction; APASL guidelines in general exclude patients with Child-Pugh A from transplantation. In patients with Child-Pugh B, transplantation is the second-line therapy, if resection is not possible for patients within Milan criteria. German and Italian guidelines recommend transplantation for all patients within Milan criteria. Whereas resection is the standard therapy of HCC in healthy liver, a standard regarding the indication for LR and transplantation for HCC in cirrhotic liver does not exist, although nearly all guidelines claim to be evidence based. Surprisingly, despite European guidelines, Germany and Italy use their own national guidelines which partially differ from the European. Possible solutions of the problems are discussed.

    Antiviral therapy for hepatitis C has the potential to improve liver function in patients with decompensated cirrhosis. To examine the virological response and effect of viral clearance in patients with decompensated hepatitis C cirrhosis all with MELD scores ≥15 following sofosbuvir/daclatasvir ± ribavirin. We prospectively collected data on patients who commenced sofosbuvir/daclatasvir for 24-weeks under the Australian patient supply program (TOSCAR) and analysed outcomes including sustained viral response at 12 weeks (SVR12), death and transplant. 108 patients (M/F, 79/29; median age 56years; Child-Pugh 10; MELD 16; genotype 1/3, 55/47) received sofosbuvir/daclatasvir and two also received ribavirin. On intention-to-treat, the SVR12 rate was 70% (76/108). Seventy-eight patients completed 24-weeks therapy. SVR12 was achieved in 56 of these patients on per-protocol-analysis (76%). SVR12 was 80% in genotype 1 compared to 69% in genotype 3. Thirty patients failed to complete therapy. In patients achieving SVR12, median MELD and Child-Pugh fell from 16(IQR15-17) to 14(12-17) and 10(9-11) to 8(7-9), respectively (P<.001). In those who died, MELD increased from 16 to 23 at death (P=.036). Patients who required transplantation had a significantly higher baseline MELD (20) compared to those patients completing treatment (16) (P=.0010). The odds ratio for transplant in patients with baseline MELD ≥20 was 13.8(95%CI 2.78-69.04). SVR12 rates with sofosbuvir/daclatasvir in advanced liver disease are lower than in compensated disease. Although treatment improves MELD and Child-Pugh in most patients, a significant proportion will die or require transplantation. In those with MELD ≥20, it may be better to delay treatment until post-transplant. © 2017 John Wiley & Sons Ltd.

    To evaluate the effectiveness of transjugular intrahepatic portosystemic shunt(TIPS) in the management of gastroesophageal variceal bleeding and predictive factors for long-term survival in patients with post-necrotic liver cirrhosis. A total of 49 patients with post-necrotic liver cirrhosis underwent TIPS over a recent three-year period. Forty-five had a history of hepatitis B viral infection, and four, of hepatitis C viral infection. In all patients, the indication for the procedure was variceal bleeding. Child-Pugh class was A in seven patients, B in 16 and C in 26 patients at the time of the last bleeding. The effectiveness of portal decompression and bleeding control was evaluated. Long-term survival was calculated by the Kaplan-Meier method and predictive factors were analyzed using the Wilcoxon test. The procedure was technically successful in all cases. The portosystemic pressure gradient decreased significantly from 21.4 ± 6.4 mmHg to 12.0 ± 5.1 mmHg(N=45). Active variceal bleeding was controlled in 34 of the 37 emergency patients. The total length of follow-up was from one day to three and a half years(mean : 383 ± 357 days). Rebleeding developed in 17 patients (35%). Hepatic encephalopathy, either newly developed or aggravated, occurred in 16 (32.7%). The thirty-day mortality rate was 20.4%, and the one-year survival rate was 63.8%. The significant predictive factors for poor prognosis were Child-Pugh class C and post-TIPS hepatic encephalopathy. TIPS is effective in portal decompression in the patients with variceal bleeding due to post-necrotic liver cirrhosis. The Child-Pugh classification and hepatic encephalopathy after TIPS are considered to be significant predictive factors for long-term survival

    Full Text Available Background. Hyperammonemia resulting from chronic liver disease (CLD can potentially challenge and damage any organ system of the body, particularly the brain. However, there is still some controversy regarding the diagnostic or prognostic values of serum ammonia in patients with over hepatic encephalopathy, especially in the setting of acute-on-chronic or chronic liver failure. Moreover, the association of serum ammonia with worsening Child-Pugh grade of liver cirrhosis has not been studied. Objective. This study was conducted to solve the controversy regarding the association between hyperammonemia and cirrhosis, especially hepatic encephalopathy in chronically failed liver. Material and Methods. In this study, 171 cirrhotic patients had their serum ammonia measured and analyzed by SPSS version 16. Chi-squared test and one-way ANOVA were applied. Results. The study had 110 male and 61 female participants. The mean age of all the participants in years was 42.33±7.60. The mean duration (years of CLD was 10.15±3.53 while the mean Child-Pugh (CP score was 8.84±3.30. Chronic viral hepatitis alone was responsible for 71.3% of the cases. Moreover, 86.5% of participants had hepatic encephalopathy (HE. The frequency of hyperammonemia was 67.3%, more frequent in males (N=81, z-score = 2.4, and P<0.05 than in females (N=34, z-score = 2.4, and P<0.05, and had a statistically significant relationship with increasing CP grade of cirrhosis (χ2(2 = 27.46, P<0.001, Phi = 0.40, and P<0.001. Furthermore, serum ammonia level was higher in patients with hepatic encephalopathy than in those without it; P<0.001. Conclusion. Hyperammonemia is associated with both increasing Child-Pugh grade of liver cirrhosis and hepatic encephalopathy.

    Endoscopic screening for high-risk gastro-oesophageal varices (GOV) is recommended for compensated cirrhotic patients with transient elastography identifying increasing numbers of patients with cirrhosis without portal hypertension. Using liver stiffness measurement (LSM) ± platelet count, the aim was to develop a simple clinical rule to exclude the presence of high-risk GOV in patients with Child-Pugh A cirrhosis. A retrospective analysis of 71 patients with Child-Pugh A cirrhosis diagnosed by transient elastography (LSM >13.6 kPa) who underwent screening gastroscopy was conducted. A predictive model using LSM ± platelet count was assessed to exclude the presence of high-risk GOV (diameter >5 mm and/or the presence of high-risk stigmata) and validated using a second cohort of 200 patients from two independent centres. High-risk GOV were present in 10 (15%) and 16 (8%) of the training and validation cohorts, respectively, which was associated with LSM and Pl count (P < 0.05). A combined model based on LSM and Pl count was more accurate for excluding the presence of high-risk GOV than either alone (training cohort AUROC: 0.87 [0.77-0.96] vs. 0.78 [0.65-0.92] for LSM and 0.71 [0.52-0.90] for platelets) with the combination of LSM ≤25 kPa and Pl ≥100 having a NPV of 100% in both the training and validation cohorts. A total of 107 (39%) patients meet this criterion. The combination of LSM ≤25 kPa and Pl ≥100 can be used in clinical practice to exclude the presence of high-risk GOV in patients with Child-Pugh A cirrhosis. © 2015 John Wiley & Sons A/S.

    The high pressure (HP) structural phase of FeB{sub 2} compound is investigated by using first-principles crystal structure prediction based on the CALYPSO technique. A thermodynamically stable phase of FeB{sub 2} with space group Imma is predicted at pressure above 225 GPa, which is characterized by a layered orthorhombic structure containing puckered graphite-like boron layers. Its electronic and mechanical properties are identified and analyzed. The feature of band structures favors the occurrence of superconductivity, whereas, the calculated Pugh's ratio reveals that the HP Imma structure exhibits ductile mechanical property. - Highlights: • The high pressure structural phase of FeB{sub 2} compound is firstly investigated by the CALYPSO technique. • A thermodynamically stable Imma phase of FeB{sub 2} is predicted at pressure above 225 GPa. • The Imma structure is characterized by a 2D boron network containing puckered graphite-like boron layers. • The band feature of Imma structure favors the occurrence of superconductivity. • The calculated Pugh's ratio suggests that the Imma structure exhibits ductile mechanical property.

    Full Text Available Fifty-seven patients with failed sclerotherapy received a mesocaval interposition shunt with an externally supported, ringed polytetrafluoroethylene prosthesis of either 10 or 12 mm diameter. Thirty-one patients had Child-Pugh gradeA disease and 26 grade B; all had a liver volume of 1000– 2500 ml. Follow-up ranged from 16 months to 6 years 3 months. Three patients (5 per cent died in the postoperative period. There were two postoperative recurrences of variceal haemorrhage and one recurrent bleed in the second year after surgery. The cumulative shunt patency rate was 95 per cent and the incidence of encephalopathy 9 per cent; the latter was successfully managed by protein restriction and/or lactulose therapy. The actuarial survival rate for the whole group at 6 years was 78 per cent, for those with Child-Pugh grade A 88 per cent and for grade B 67 per cent. Small-lumen mesocaval interposition shunting achieves portal decompression, preserves hepatopetal flow, has a low incidence of shunt thrombosis, prevents recurrent variceal bleeding and is not associated with significant postoperative encephalopathy.

Methods From December 2011 to January 2012, we completed two cases of unpaid organ donation after brain death. All donors were diagnosed as brain death, and maintained with mechanical ventilation and vasoactive drug therapy to guarantee the perfusion of donor organs. All recipients were male, the preoperative diagnosis was hepatitis B cirrhosis, liver decompensation, Child-Pugh class C, MELD score 29 points, and hepatitis B cirrhosis, primary liver cancer, Child-Pugh class C, MELD score 26 points. Results In these two cases, we successfully procured donor's livers, and livers were successfully transplanted into all recipients, and working well during the follow-up period. Conclusion The implementation of liver transplantation using organs from brain death donors can gradually extended in our country, and is important to ease the shortage of organ pool.%目的 总结并探讨脑死亡无偿器官捐献肝脏移植在我国临床实施的可行性.方法 昆明市第一人民医院于2011年12月至2012年1月期间共完成2例脑死亡无偿器官捐献工作.2例供体确诊为脑死亡,应用机械通气、血管活性药物等治疗维持供体器官灌注.受体1男性,术前诊断乙肝后性肝硬化,肝功能失代偿,child-pugh C级,MELD评分29分;受体2男性,术前诊断乙肝后性肝硬化,原发性肝癌,child-pugh C级,MELD评分26分.结果 2例脑死亡供体均顺利无偿捐献肝脏,2例受体均顺利接受肝脏移植手术并康复出院,目前随访移植肝功能良好.结论 脑死亡无偿器官捐献肝脏移植的临床实施顺利,可以在我国逐渐推广实行,对缓解我国目前器官短缺状况起到相当重要的作用.

    The Alpha-X RF-gun was designed to produce an ultra-short (laser-driven plasma accelerator with a short wavelength accelerating medium. It has been demonstrated on PHIL (Photo-Injector at LAL) that the coaxial RF coupling, chosen to preserve the gun field cylindrical symmetry, is perfectly understood and allows reaching the required peak accelerating field of 100 MV/m giving beam energy of 6.3 MeV. Moreover, a quite low beam rms relative energy spread of 0.15% at 3.8 MeV has been measured, completely agreeing with simulations. Dark current, quantum efficiencies and dephasing curves measurements have also been performed. They all show high values of the field enhancement factor β, which can be explained by the preparation of the photocathodes. Finally, measurements on the transverse phase-space have been carried out, with some limitations given by the difficult modelization of one of the PHIL solenoid magnets and by the enlargement of the beam transverse dimensions due to the use of YAG screens. These measurements give a normalized rms transverse emittance around 5π mm mrad, which does not fulfill the requirement for the Alpha-X project.

    Purpose: It has been reported that the branched-chain amino acid (BCAA) to aromatic amino acid (AAA) ratio (Fisher $B!G (Bs ratio) is an important prognostic factor in cirrhosis. The clinical significance of the ratio of serum molar concentration of BCAA to that of tyrosine (BCAA to tyrosine ratio; BTR) resembles that of Fisher $B!G (Bs ratio, In Japan, because determination of BTR simpler and cheaper than that of Fisher $B!G (Bs ratio, BTR is now widely used for assessment of abnormality of amino acid metabolism in cirrhosis. In this study, we examined the difference between early cirrhotic patients with lower BTR and higher BTR in portal circulation using per-rectal portal scintigraphy with technetium-99m ( 99m Tc) pertechnetate. Patients and Methods: Forty patients with Child-Pugh grade A cirrhosis and serum albumin level between 3.5 g/dl and 3.9 g/dl were enrolled in this study. Sixteen patients were infected with HBV and 24 with HCV. At entry, we measured the ratio of serum molar concentration of BCAA to that of tyrosine (BTR). BTR was measured by an enzymatic method (Ono Pharmaceutical Co., Ltd., Osaka, Japan). Thirteen patients had BTR 4.0. At the same time, we measured serum albumin, platelets, total bilirubin, prothrombin test, retention of indocyanine green in plasma after 15 minutes (ICGR-15) and NH3. To evaluate the portal circulation, all patients underwent per-rectal portal scintigraphy. A 370 MBq portion of 99m Tc-pertechnetate (2 ml) was first given per rectum through a polyethylene tube, followed by 15 ml of air. Then time-activity curves for the heart and liver areas were obtained every 4 sec. At the enol of the 5 min-examinations, the 5-min summed image displayed in color was recorded. To evaluate the extent of porta-systemic shunt by shunt index (SI), we calculated the ratio of counts for the liver to counts for the heart integrated for 24 seconds immediately after the appearance of the liver time-activity curve. Results: Shunt index obtained

    Heliotropium glutinosum Phil. (Heliotropiceae) is a resinous bush that grows at a height of 2000 m in Chañaral, Chile. From the resinous exudates of Heliotropium glutinosum Phil. a new aromatic geranyl derivative: 4-methoxy-3-[(2)-7'-methyl-3'-hydroxymethyl-2',6'-octadienyl] phenol (1) and three flavonoids: 5,3'-dihydroxy-7,4'-dimethoxyflavanone (2), 5,4'-dihydroxy-7-methoxyflavanone (3) and 4'-acetyl-5-hydroxy-7-methoxyflavanone (4) were isolated and their structures were determined. Their antioxidant activity were evaluated using the bleaching of ABTS and DPPH derived cation radical methods and expressed in terms of FRE (fast reacting equivalents) and TRE (total reacting equivalents), where FRE is a good measure of the quick protection of a given compound against oxidants and TRE measures the degree of long-term protection of the antioxidant, or how effective it is against a strong oxidative stress.

    Two new Erenna species, E. insidiator sp. nov. and E. sirena sp. nov., are described from specimens collected in the vicinity of Monterey Bay, California, and also, for E. sirena at the southern end of the Gulf of California, Mexico. Further information on the three extant Erenna species is given, based on specimens collected in the same areas. These have enabled, for instance, the identification of three types of tentilla on the tentacles of E. cornuta Pugh, 2001, rather than the two noted on the single previously known specimen. The genus is remarkable for the presence of bioluminescent lures on the tentilla of all five species. In E. sirena sp. nov. the tentilla are also covered by a red-fluorescent layer, which was briefly described by Haddock et al. (2005), and further details are given herein. Another extraordinary feature of the colonies E. sirena sp. nov. is that the main part of the tentacle, with its tentilla, can be extended away from the siphosomal stem on a long peduncle. This phenomenon also appears to occur in E. laciniata Pugh, 2001, and has not been observed before for other physonect species.

    Aim: To evaluate the safety and efficacy of combined therapy with transarterial chemoembolization (TACE) and sorafenib for hepatocellular carcinoma (HCC) with portal venous tumour thrombus (PVTT). Materials and methods: This study was approved by the institutional review board. From May 2009 to May 2012, 170 consecutive patients were newly diagnosed with advanced-stage HCC and treated with TACE plus sorafenib. Among them, 41 patients with PVTT were retrospectively enrolled in the study. The adverse events (AEs), overall survival (OS), time to progression (TTP), and prognostic factors were analysed. Statistical analysis was performed with the Kaplan–Meier method using the log-rank test and Cox regression models. Results: The most common AEs were hand–foot skin reaction related to sorafenib and fever related to TACE. Procedure-related mortality and grade 4 AEs were not observed. Grade 3 AEs were observed in five patients. During the median follow-up period of 13.5 months (range 1.4–45 months), the 6-month and 1-year survival rates were 87.7% and 53.6%, respectively. The median OS was 13 months (range 1.4–44.8 months), and the median TTP was 7 months (range 1–18.6 months). The Child–Pugh class (p = 0.022), extrahepatic metastasis (p = 0.009), and gross morphological type (nodular type versus diffuse type; p = 0.008) were prognostic factors related to OS in the multivariate analysis. Conclusion: TACE plus sorafenib in an interrupted therapeutic scheme was well tolerated and might improve OS for HCC patients with PVTT, especially in those with Child–Pugh class A, no extrahepatic metastasis, or nodular-type HCC. - Highlights: • We introduce the safety of TACE plus sorafenib for patients with advanced HCC and PVTT. • We suggest that the combined therapy might prolong the TTP and OS than sorafenib alone. • Clinic benefit determinations with the Child-Pugh class, extrahepatic metastasis or gross type

    2011-01-01

    To evaluate the extent of pain response and objective response to palliative radiotherapy (RT) for bone metastases from hepatocellular carcinoma according to RT dose. From January 2007 to June 2010, palliative RT was conducted for 103 patients (223 sites) with bone metastases from hepatocellular carcinoma. Treatment sites were divided into the high RT dose and low RT dose groups by biologically effective dose (BED) of 39 Gy10. Pain responses were evaluated using the numeric rating scale. Pain scores before and after RT were compared and categorized into 'Decreased', 'No change' and 'increased'. Radiological objective responses were categorized into complete response, partial response, stable disease and progression using modified RECIST (Response Evaluation Criteria In Solid Tumors) criteria; the factors predicting patients' survival were analyzed. The median follow-up period was 6 months (range, 0 to 46 months), and the radiologic responses existed in 67 RT sites (66.3%) and 44 sites (89.8%) in the high and low RT dose group, respectively. A dose-response relationship was found in relation to RT dose (p=0.02). Pain responses were 75% and 65% in the high and low RT dose groups, respectively. However, no statistical difference in pain response was found between the two groups (p=0.24). There were no differences in the toxicity profiles between the high and low RT dose groups. Median survival from the time of bone metastases diagnosis was 11 months (range, 0 to 46 months). The Child-Pugh classification at the time of palliative RT was the only significant predictive factor for patient survival after RT. Median survival time was 14 months under Child-Pugh A and 2 months under Child-Pugh B and C. The rate of radiologic objective response was higher in the high RT dose group. Palliative RT with a high dose would provide an improvement in patient quality of life through enhanced tumor response, especially in patients with proper liver function.

    Full Text Available ObjectiveHCV infection is a leading cause of chronic liver disease with long-term complications—extensive fibrosis, cirrhosis, and hepatocellular carcinoma. The objective of this study is to perform cost analysis of therapy of patients with chronic HCV-related cirrhosis hospitalized in the University Hospital “Queen Joanna-ISUL” for 3-year period (2012–2014.MethodsIt is a prospective, real life observational study of 297 patients with chronic HCV infection and cirrhosis monitored in the University Hospital “Queen Joanna-ISUL” for 3-year period. Data on demographic, clinical characteristics, and health-care resources utilization (hospitalizations, highly specialized interventions, and pharmacotherapy were collected. Micro-costing approach was applied to evaluate the total direct medical costs. The points of view are that of the National Health Insurance Fund (NHIF, hospital and the patients. Collected cost data are from the NHIF and hospitals tariffs, patients, and from the positive dug list for medicines prices. Descriptive statistics, chi-squared test, Kruskal–Wallis, and Friedman tests were used for statistical processing.Results76% of patients were male. 93% were diagnosed in grade Child-Pugh A and B. 97% reported complications, and almost all developed esophageal varices. During the 3 years observational period, patients did not change the critical clinical values for Child-Pugh status and therefore the group was considered as homogenous. 847 hospitalizations were recorded for 3 years period with average length of stay 17 days. The mortality rate of 6.90% was extremely high. The total direct medical costs for the observed cohort of patients for 3-year period accounted for 1,290,533 BGN (€659,839 with an average cost per patient 4,577 BGN (€2,340. Statistically significant correlation was observed between the total cost per patient from the different payers’ perspective and the Child-Pugh cirrhosis score

    AIM: To evaluate outcomes of radiofrequency ablation (RFA) therapy for early hepatocellular carcinoma (HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography (CT) or magnetic resonance imaging (MRI) (single nodule of ≤ 5 cm, or multi- (up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Câncer do Estado de São Paulo, Brazil were enrolled in the study. RFA of the liver tumors (with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response (absence of enhancing tissue at the tumor site) or incomplete response (enhancing tissue remaining at the tumor site). Overall survival and disease-free survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients (age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo (range, 1-33). The study population showed predominance of male sex (76%), less severe liver disease (Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor (65%). The maximum tumor diameters ranged from 10 to 50 mm (median, 26 mm). The initial (immediately post-procedure) rate of RFA-induced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule (vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema (resolved with intervention) and intestinal perforation

    To evaluate the usefulness of renal resistive index(RI) in patients with liver cirrhosis as an indicator for predicting hepatorenal syndrome. Renal RIs of thirty cirrhotic patients were analyzed using the gray-scale and Doppler ultrasonograms. As a control group, eight normal subjects were included. Renal RIs were measured at three sites of interlobar or arcuate arteries of both kidneys. The patients were divided into three groups (A, B, or C) according to the Child-Turcotte-Pugh classification and their serum BUN and creatinine levels were compared. We determined whether RIs of normal controls differed from those of cirrhotic patients or whether RIs of cirrhotic patients correlated with the Child-Turcotte-Pugh classification or BUN and creatinine levels. Mean RIs(0.63 {+-}0.33) of normal subjects were statistically different from those(0.67 {+-} 0.05) of cirrhotic patients(P=0.009). RIs of group A(n=6), B(n=9) and C(n=15) were 0.65 {+-} 0.03, 0.65 {+-} 0.04 and 0.70 {+-} 0.04, respectively. The ANOVA test revealed statistically significant differences between the three groups(F ratio=4.472, P=0.021). RIs did not correlate with BUN or creatinine levels. RI could be used as an index for predicting hepatorenal syndrome before the renal function becomes impaired.

    The purpose of this study was to investigate the chronological relationship between scan delay and liver enhancement for the hepatobiliary phase on Gd-EOB-DTPA-enhanced MRI and evaluate the effects of liver function on liver enhancement. Hepatobiliary-phase images were retrospectively evaluated in 125 patients with chronic liver disease. Hepatobiliary phase images were obtained at 5, 10, 15, and 20 min after injection. We calculated relative liver enhancement (RLE) at t min after injection by dividing the signal intensity (SI) of the liver at t min by precontrast SI. We compared RLE values at 5, 10, 15, and 20 min and evaluated the detectability of focal hepatic lesions. We analyzed the effect of liver function on RLE with the generalized linear model. There was not significant difference in RLE and lesion detectability at 15 and 20 min. RLE in the Child-Pugh C group was significantly lower than in the Child-Pugh A and B groups. The serum albumin level and prothrombin time were significantly correlated with the liver enhancement. A delay time of 15 min for the hepatobiliary phase was thought to be adequate in patients with mild liver dysfunction. The serum albumin level and prothrombin time would be predictive of liver enhancement in the hepatobiliary phase. (author)

    Purpose: To retrospectively evaluate the safety and effectiveness of repeated proton beam therapy for newly developed or recurrent hepatocellular carcinoma (HCC). Methods and Materials: From June 1989 through July 2000, 225 patients with HCC underwent their first course of proton beam therapy at University of Tsukuba. Of them, 27 with 68 lesions who had undergone two or more courses were retrospectively reviewed in this study. Median interval between the first and second course was 24.5 months (range 3.3-79.8 months). Median total dose of 72 Gy in 16 fractions and 66 Gy in 16 fractions were given for the first course and the rest of the courses, respectively. Results: The 5-year survival rate and median survival period from the beginning of the first course for the 27 patients were 55.6% and 62.2 months, respectively. Five-year local control rate for the 68 lesions was 87.8%. Of the patients, 1 with Child-Pugh class B and another with class C before the last course suffered from acute hepatic failure. Conclusions: Repeated proton beam therapy for HCC is safe when the patient has a target in the peripheral region of the liver and liver function is Child-Pugh class A

    The Alpha-X RF-gun was designed to produce an ultra-short (<100 fs rms), 100 pC and 6.3 MeV electron beam with a normalized rms transverse emittance of 1π mm mrad for a gun peak accelerating field of 100 MV/m. Such beams will be required by the Alpha-X project, which aims to study a laser-driven plasma accelerator with a short wavelength accelerating medium. It has been demonstrated on PHIL (Photo-Injector at LAL) that the coaxial RF coupling, chosen to preserve the gun field cylindrical symmetry, is perfectly understood and allows reaching the required peak accelerating field of 100 MV/m giving beam energy of 6.3 MeV. Moreover, a quite low beam rms relative energy spread of 0.15% at 3.8 MeV has been measured, completely agreeing with simulations.

Finally, measurements on the transverse phase-space have been carried out, with some limitations given by the difficult modelization of one of the PHIL solenoid magnets and by the enlargement of the beam transverse dimensions due to the use of YAG screens. These measurements give a normalized rms transverse emittance around 5π mm mrad, which does not fulfill the requirement for the Alpha-X project.

    Full Text Available Objective: to assess the safety and efficacy of laparoscopy in the treatment of symptomatic cholelithiasis in patients with Child´s Class A and Class B cirrhosis. Study design: descriptive and retrospective study. Patients: we studied 14 patients (mean age 60 yrs with Child´s Class A and Class B hepatic cirrhosis who underwent laparoscopic cholecystectomy. We analyzed the occurrence of intraoperative and postoperative complications. Results: eight patients were women (57.14% and 6 were men (42.85%. Eight of the 14 patients presented with Child's Class B cirrhosis and 6 patients with Class A. Cholecystectomy was programmed for all patients. The average duration of surgery was 77 min. Intraoperative complications occurred in 2 patients (14.28% in the form of liver bed bleeding. Postoperative complications were observed in 3 patients (21.42%, 2 presented with ascites which led to a worsening of Child's Class in one of them, and the third patient presented with angina-like symptoms (acute, sharp pain in the chest irradiating to the back. Mean length of hospital stay was 3 days. No postoperative morbidity or mortality occurred, and there were no conversions. Conclusions: LC (laparoscopic cholecystectomy is a safe and effective alternative for the treatment of symptomatic cholelithiasis in patients with well-compensated Child's Class A and Class B cirrhosis. Postoperative morbi-mortality is low, bleeding is unimportant, and both duration of surgical procedure and hospital stay are short.Objetivo: evaluar la seguridad y eficacia del uso de la laparoscopia en pacientes cirróticos en estadio A y B de Child-Pugh con colelitiasis sintomática.

    Purpose. To Evaluate the MELD score as a predictor of 30-day mortality in patients undergoing elective TIPS procedures. Methods. This was a retrospective, IRB-approved study. The medical records of all patients who underwent a TIPS procedure between May 1, 1999 and June 1, 2003 in a single institution were reviewed. Patients who underwent elective TIPS were selected. Elective TIPS was performed in 119 patients with a mean age of 55.1 (± 9.6) years. The MELD and Child-Pugh scores before TIPS, etiology of cirrhosis, portosystemic gradients before and after TIPS, procedure time, and procedural complications were obtained from the medical records. The MELD and Child-Pugh scores before TIPS were compared between the survivor group (SG) and the early death (EDG) group. The early death rate was calculated for MELD score subgroups (1-10, 11-17, 18-24, and >24). Data were analyzed using the Fisher exact test, chi-square test and independent-sample t-test. A p value of less than 0.05 was considered significant. Results. Technical success rate was 100%. The early death rate was 10.9% (13/119). The mean MELD scores before TIPS were 19.4 (± 5.9) (EDG) and 14 (± 4.2) (SG) (p = 0.025). The early death rate was highest in the pre-TIPS MELD > 24 subgroup. The Child-Pugh scores were 9.0 (± 1.6) (SG) and 9.8 ± 1.06 (EDG) (p 0.08). The mean portosystemic gradients before TIPS were 20.5 (± 7.7) mmHg (EDG) and 22.7 (± 7.3) (SG) (p > 1) and the mean portosystemic gradients after TIPS were 6.5 (± 3.5) (EDG) and 6.9 (± 2.4) (SG) (p > 1). The mean procedural times were 95.6 (± 8.4) min (EDG) and 89.2 (± 7.5) min (SG) (p > 1). No early death was attributed to a fatal complication during TIPS. Conclusion. The MELD score is useful in identifying patients at a higher risk of early death after an elective TIPS. On the basis of our results, we do not endorse elective TIPS in patients with MELD scores > 24

    To determine the utility of liver T1-mapping on gadolinium-ethoxybenzyl-diethylenetriamine-pentaacetic acid (Gd-EOB-DTPA) enhanced magnetic resonance (MR) imaging for the measurement of liver functional reserve compared with the signal intensity (SI) based parameters, technetium-99m-galactosyl serum albumin ( 99m Tc-GSA) scintigraphy and indocyanine green (ICG) clearance. This retrospective study included 111 patients (Child-Pugh-A 90; -B 21) performed with both Gd-EOB-DTPA enhanced liver MR imaging and 99m Tc-GSA (76 patients with ICG). Receiver operating characteristic (ROC) curve analysis was performed to compare diagnostic performances of T1-relaxation-time parameters [pre-(T1pre) and post-contrast (T1hb) Gd-EOB-DTPA], SI based parameters [relative enhancement (RE), liver-to-muscle-ratio (LMR), liver-to-spleen-ratio (LSR)] and 99m Tc-GSA scintigraphy blood clearance index (HH15)] for Child-Pugh classification. Pearson's correlation was used for comparisons among T1-relaxation-time parameters, SI-based parameters, HH15 and ICG. A significant difference was obtained for Child-Pugh classification with T1hb, ΔT1, all SI based parameters and HH15. T1hb had the highest AUC followed by RE, LMR, LSR, ΔT1, HH15 and T1pre. The correlation coefficients with HH15 were T1pre 0.22, T1hb 0.53, ΔT1 -0.38 of T1 relaxation parameters; RE -0.44, LMR -0.45, LSR -0.43 of SI-based parameters. T1hb was highest for correlation with HH15. The correlation coefficients with ICG were T1pre 0.29, T1hb 0.64, ΔT1 -0.42 of T1 relaxation parameters; RE -0.50, LMR -0.61, LSR -0.58 of SI-based parameters; 0.64 of HH15. Both T1hb and HH15 were highest for correlation with ICG. T1 relaxation time at post-contrast of Gd-EOB-DTPA (T1hb) was strongly correlated with ICG clearance and moderately correlated HH15 with 99m Tc-GSA. T1hb has the potential to provide robust parameter of liver functional reserve. Copyright © 2017 Elsevier B.V. All rights reserved.

    This paper discusses how information communication technology (ICT) can facilitate high quality teaching and learning for dyslexic children and their spelling. Previous research has suggested that ICT can have a positive effect on dyslexic children’s spelling ability and confidence (Lange et al, 2006, Tuner and Pughe, 2003). The use of an IPad therefore was utilised in small group spelling sessions to assess the effect ICT, specifically IPads, can have on pupils who have a diagnosis of dyslex...

    Copao (Eulychnia acida Phil., Cactaceae) is an endemic species occurring in northern Chile. The edible fruits of this plant are valued for its acidic and refreshing taste. Phenolic-enriched extracts from copao fruit pulp and epicarp, collected in the Elqui and Limari river valleys, were assessed by its in vitro ability to inhibit the pro-inflammatory enzymes lipoxygenase (LOX) and cyclooxygenases (COX-1 and COX-2). At 100 μg/mL, pulp extracts showed better effect towards LOX than epicarp extract, while COX-2 inhibition was observed for both epicarp and pulp samples. In general, the extracts were inactive towards COX-1. A positive correlation was observed between the anti-inflammatory activity and the main phenolic compounds found in this fruit. Copao fruits from the Limari valley, a main place of collection and commercialization, showed major activity, adding evidence on the possible health-beneficial effects of this native Chilean fruit.

    Full Text Available Traditional Chinese medicine (TCM syndrome is an important basis for TCM diagnosis and treatment. As Child-Pugh classification as well as compensation and decompensation phase in liver cirrhosis, it is also an underlying clinical classification. In this paper, we investigated the correlation between single nucleotide polymorphisms (SNPs of Interleukin-10 (IL-10 and TCM syndromes in patients with hepatitis B cirrhosis (HBC. Samples were obtained from 343 HBC patients in China. Three SNPs of IL-10 (−592A/C, −819C/T, and −1082A/G were detected with polymerase chain-reaction-ligase detection reaction (PCR-LDR. The result showed the SNP-819C/T was significantly correlated with Deficiency syndrome (P=0.031, but none of the 3 loci showed correlation either with Child-Pugh classification and phase in HBC patients. The logistic regression analysis showed that the Excess syndrome was associated with dizzy and spider nevus, and the Deficiency syndrome was associated with dry eyes, aversion to cold, IL-10-819C/T loci, and IL-10-1082A/G loci. The odds ratio (OR value at IL-10-819C/T was 4.022. The research results suggested that IL-10-819C/T locus (TC plus CC genotype is probably a risk factor in the occurrence of Deficiency syndrome in HBC patients.

    To evaluate the usefulness of renal resistive index(RI) in patients with liver cirrhosis as an indicator for predicting hepatorenal syndrome. Renal RIs of thirty cirrhotic patients were analyzed using the gray-scale and Doppler ultrasonograms. As a control group, eight normal subjects were included. Renal RIs were measured at three sites of interlobar or arcuate arteries of both kidneys. The patients were divided into three groups (A, B, or C) according to the Child-Turcotte-Pugh classification and their serum BUN and creatinine levels were compared. We determined whether RIs of normal controls differed from those of cirrhotic patients or whether RIs of cirrhotic patients correlated with the Child-Turcotte-Pugh classification or BUN and creatinine levels. Mean RIs(0.63 ±0.33) of normal subjects were statistically different from those(0.67 ± 0.05) of cirrhotic patients(P=0.009). RIs of group A(n=6), B(n=9) and C(n=15) were 0.65 ± 0.03, 0.65 ± 0.04 and 0.70 ± 0.04, respectively. The ANOVA test revealed statistically significant differences between the three groups(F ratio=4.472, P=0.021). RIs did not correlate with BUN or creatinine levels. RI could be used as an index for predicting hepatorenal syndrome before the renal function becomes impaired

    The present study evaluated whether oral supplementation with a branched-chain amino acid (BCAA) improves the biochemical and amino acid profiles of liver tumor patients undergoing radiotherapy. Patients were randomly assigned to one of 2 groups: a group given oral supplementation with BCAA granules (LIVACT granules; Samil Pharm Co., Korea, each granule containing L-isoleucine 952 mg, L-leucine 1,904 mg, and L-valine 1,144 mg) during radiotherapy, or a placebo group. Physical and biochemical examinations and measurements, including subjective symptoms, Child-Pugh class, body mass index, plasma albumin concentration, and plasma amino acid profiles were monitored. Fifty were enrolled between November 2005 and November 2006. We also analyzed data from 37 hepatocellular carcinoma (HCC) patients in order to evaluate a more homogenous group. The two groups of patients were comparable in terms of age, gender, Child-Pugh score, and underlying hepatitis virus type. Serum albumin, total protein, liver enzymes, and cholesterol showed a tendency to increase in the BCAA group. In this group, the percentage of cases that reverted to normal serum albumin levels between 3 and 10 weeks after administration of BCAA was significantly higher (41.18%) than in the placebo group (p=0.043). Oral supplementation with a BCAA preparation seems to help HCC patients undergoing radiotherapy by increasing the BCAA concentration.

    Ethane exhalation was measured in 42 control subjects, 52 patients with various non-alcoholic liver diseases, and 89 alcohol abusers who had been admitted to hospital for alcohol withdrawal and assessment of liver disease (six with normal liver tests, 10 with steatosis with or without fibrosis, six with alcoholic hepatitis, 29 with cirrhosis, 34 with both cirrhosis and alcoholic hepatitis, and four with both cirrhosis and a hepatocellular carcinoma). Ethane exhalation was similar in control subjects and in patients with non-alcoholic liver diseases, but was five times higher in alcohol abusers. Ethane exhalation in alcohol abusers was significantly, but very weakly, correlated with the daily ethanol intake before hospital admission, and the histological score for steatosis, but not with the inflammation or alcoholic hepatitis scores. Ethane exhalation was inversely correlated with the duration of abstinence before the test. In nine alcoholic patients, the exhalation of ethane was measured repeatedly, and showed slow improvement during abstinence. Ethane exhalation was significantly but weakly correlated with the Pugh's score in patients with alcoholic cirrhosis. It is concluded that the mean ethane exhalation is increased in alcohol abusers. One of the possible mechanisms may be the presence of oxidizable fat in the liver. The weak correlation with the Pugh's score is consistent with the contribution of many other factors in the progression to severe liver disease. PMID:8472992

    Lipid metabolism disorders usually occurred in chronic liver disease. A cross- sectional study was conducted in liver cirrhosis (LC) patients who came to Central Hospital Haji Adam Malik, Medan on July-December 2016 to evaluatethe comparison of total cholesterol, LDL, HDL, triglyceride in Child-Pugh class. Inclusions criteria were apatient diagnosed with LC from anamnesis, physic diagnostic, laboratory, and imaging. The patientswere being evaluated with Child-Pugh (CP). P-value was calculated by using univariate and bivariate analysis of variance test (ANOVA). There were 80 subjects which included 45 men (56.3%) and 35 women (43.8%). Mean age was 51.36±12.6 years. There were 40% with HBsAg(+) and 12.5% with Anti-HCV (+). There was 60% patient with CP-C, 21.3% CP-B, and 18.8% CP-A. There were significant differences between LDL and HDL level among LC patient grade in CP-A, B, and C (p<0.05). HDL and LDL level significantly lower in CP-C compared with CP-A. There were significantly differences between LDL and HDL level among LC patient grade in CP-A, B, and C (p<0.05). HDL and LDL level significantly lower in CP-C compared with CP-A. There weren’t any statistically difference between total cholesterol and triglyceride level in LC patients with CP- A, B, and C.

    Full Text Available Context Liver cirrhosis patients with hepatocellular carcinoma present nutritional alterations and metabolic disorders that negatively impact the prognosis. Objective The objective is to identify alterations in the metabolism of macro and micronutrients among liver cirrhosis patients with and without hepatocellular carcinoma and their relation to the Child-Turcote-Pugh score and Barcelona Clinic Liver Cancer staging. Methods Analytical transversal study, with 31 hepatocellular carcinoma patients and 48 liver cirrhosis patients. Laboratorial exams were carried out. The existence of an association between the biochemical parameters and the disease severity as well as the presence of hepatocellular carcinoma was assessed. Results The metabolic-nutritional profile of liver cirrhosis patients caused by the hepatitis C virus and hepatocellular carcinoma showed alterations, specifically the lipid (total cholesterol, HDL and triglycerides, protein (albumin, creatinine and uric acid, iron (transferrin, iron and ferritin saturation, hematocrit and hemoglobin, zinc and B12 vitamin profiles. There is a relation between nutritional biochemical markers and the Child-Turcote-Pugh, as well as Barcelona Clinic Liver Cancer staging. Conclusions Considering the existence of alterations in the metabolism of nutrients in liver cirrhosis patients with and without hepatocellular carcinoma, and also that conventional nutritional assessment methods present limitations for this population, the biochemical laboratorial exams are valid to complement the diagnosis of the nutritional state in a quick and practical manner.

    The purpose of this study is to evaluate the relationship between right inferior phrenic artery diameter and portal hypertension in cirrhotic patients. CT examinations of 38 patients with chronic liver disease (patient group) and 40 patients without any liver disease (control group) were evaluated. The right inferior phrenic artery diameter of the patient and control group were measured. CT findings of portal hypertension, which were accepted as ascites, collaterals, splenomegaly and portal vein diameter greater than 13 mm, were determined and scored in the patient group. Patients obtained scores between one and four with respect to portal hypertension findings, and the scores were compared with phrenic artery diameters. Child-Pugh and MELD scores of the patients were also calculated. The mean diameter of the right inferior phrenic artery in the patient group was larger than that in the control group (p phrenic artery diameter of the patients with score 1 was significantly different from those with score 2 (p = 0.028), score 3 (p = 0.001) and score 4 (p = 0.005). We found a linear and moderate relationship between phrenic artery diameter values and Child-Pugh scores (p = 0.012, r = 0.405). Dilatation of the right inferior phrenic artery in cirrhotic patients may be a nonspecific sign of developing portal hypertension.

    The liver plays a fundamental role in iron homeostasis. Iron parameters change, especially ferritin, need to be evaluated in patients with liver cirrhosis. Serum ferritin could predict the prognosis of patients with decompensated cirrhosis since it reflects immunemediated and infectious stimuli. Ferritin could express the severity of liver disease and possible subsequent complications. Finally, it might reflect an iron overload condition resulting in significant morbidity and early mortality. 70 patients with decompensated liver cirrhosis divided into three Child-Pugh subgroups. Serum iron parameters include serum iron (SI), total iron binding capacity (TIBC) and ferritin was measured in these groups. From these 70 patients, 30 (42.9%) with HbsAg positive, 26 (37.1%) with anti-HCV positive and 14 (20%) with both HbsAg and anti-HCV positive. Of the 70 patients, 14 (20%) had CTP Class A cirrhosis, 17 (24.3%) had CTP Class B cirrhosis, and 39 (55.7%) had CTP C cirrhosis. The median (range) value of serum iron was 36 (10-345) μg/dl, TIBC was 160 (59-520) μg/dl, Ferritin was 253.5 (8-6078) ng/ml and the transferrin saturation was 22.9 (3.65-216.98) %.We found a significant difference in serum ferritin level with CTP score. Ferritin levels increased as Child-Pugh class progressed (p<0.001).

    To clarify the prevalence of occult hepatitis B virus (HBV) infection (OBI) and the association between OBI and liver disease progression, defined as development of liver cirrhosis or hepatocellular carcinoma (HCC), worsening of Child-Pugh class, or mortality in cases of chronic hepatitis C virus (HCV) infection. This prospective cohort study enrolled 174 patients with chronic HCV infection (chronic hepatitis, n = 83; cirrhosis, n = 47; HCC, n = 44), and evaluated disease progression during a mean follow-up of 38.7 mo. OBI was defined as HBV DNA positivity in 2 or more different viral genomic regions by nested polymerase chain reaction using 4 sets of primers in the S, C, P and X open reading frame of the HBV genome. The overall OBI prevalence in chronic HCV patients at enrollment was 18.4%, with 16.9%, 25.5% and 13.6% in the chronic hepatitis C, liver cirrhosis and HCC groups, respectively ( P = 0.845). During follow-up, 52 patients showed disease progression, which was independently associated with aspartate aminotransferase > 40 IU/L, Child-Pugh score and sustained virologic response (SVR), but not with OBI positivity. In 136 patients who were not in the SVR state during the study period, OBI positivity was associated with neither disease progression, nor HCC development. The prevalence of OBI in chronic HCV patients was 18.4%, and OBI was not associated with disease progression in South Koreans.

    Full Text Available Background. Advanced HCC is a clinical challenge with limited treatment options. The multikinase inhibitor sorafenib is the first and only agent showing a survival benefit in these patients. In this study we evaluate the efficacy and tolerability of sorafenib in an unselected patient population. Furthermore we explore the role of alpha-fetoprotein (αFP as a potential biomarker for treatment efficacy and correlation to survival. Methods. Seventy-six patients with advanced HCC, not eligible for locoregional therapy, treated with sorafenib between 2007 and 2009 were included. Followup was until 2011. Results. Patients in PS 0-1 had a median overall survival (mOS of 6.2 months, compared to 1.8 months in patients with poorer PS (P=0.005. Child-Pugh A patients had a mOS of 6.6 months versus 3.6 months among patients in Child-Pugh B or C (P=0.0001. Serum αFP ≥ 200 at baseline was prognostic for a shorter survival. All patients with radiologically verified tumor response and baseline αFP ≥ 200 experienced a significant decline in αFP within the first four weeks of treatment. Conclusion. The survival of patients with advanced HCC treated with sorafenib is dependent on performance status and liver function. Treatment of patients with compromised liver function and poor performance status cannot be recommended. The correlation between αFP and objective tumor response warrants further investigation.

    To determine whether multislice T1 mapping of the liver using a modified look-locker inversion recovery (MOLLI) sequence on gadoxetic acid-enhanced magnetic resonance imaging (MRI) can be used as a quantitative tool to estimate liver function and predict the presence of oesophageal or gastric varices. Phantoms filled with gadoxetic acid were scanned three times using MOLLI sequence to test repeatability. Patients with chronic liver disease or liver cirrhosis who underwent gadoxetic acid-enhanced liver MRI including MOLLI sequence at 3 T were included (n = 343). Pre- and postcontrast T1 relaxation times of the liver (T1liver), changes between pre- and postcontrast T1liver (ΔT1liver), and adjusted postcontrast T1liver (postcontrast T1liver-T1spleen/T1spleen) were compared among Child-Pugh classes. In 62 patients who underwent endoscopy, all T1 parameters and spleen sizes were correlated with varices. Phantom study showed excellent repeatability of MOLLI sequence. As Child-Pugh scores increased, pre- and postcontrast T1liver were significantly prolonged (P < 0.001), and ΔT1liver and adjusted postcontrast T1liver decreased (P< 0.001). Adjusted postcontrast T1liver and spleen size were independently associated with varices (R{sup 2} = 0.29, P < 0.001). T1 mapping of the liver using MOLLI sequence on gadoxetic acid-enhanced MRI demonstrated potential in quantitatively estimating liver function, and adjusted postcontrast T1liver was significantly associated with varices.

    The benefits of combined systemic and liver-directed treatments in inoperable intermediate- or advanced-stage hepatocellular carcinoma (HCC) have yet to be defined. This article presents the planned safety analyses for the first 40 patients randomized to radioembolization with yttrium-90 ((90) Y) resin microspheres followed by sorafenib (n = 20) or sorafenib only (n = 20) in the SORAMIC study. Patients identified for palliative treatment who were poor candidates for transarterial (chemo)embolization (including those failing TACE) with preserved liver function (Child-Pugh ≤B7) and ECOG performance status arm. Patients were followed up for a median of 8.3 months. Median total implanted activity of (90) Y was 1.87 (range: 0.54-2.35) GBq. Patients received a similar intensity and duration of sorafenib in the combination-treatment arm (median daily dose 614 mg over 8.5 months) and control arm (557 mg over 9.6 months). The incidence of total (196 vs. 222) and grade ≥3 (43 vs. 47) adverse events was similar in combination-treatment arm and control arm respectively (P > 0.05). No significant differences in the number of total or grade 3/4 toxicities were recorded for: total bilirubin, albumin, liver enzymes, ascites, Child-Pugh, fatigue, hand-foot skin reaction, blood pressure or diarrhoea. Radioembolization followed by sorafenib appears to be as well tolerated as sorafenib alone. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The full-potential linearized augmented plane wave method in the stable Fm-3m phase has been implemented to investigate the structural, elastic, magnetic and electronic properties of Cu{sub 2}MnGa. The optimized equilibrium lattice parameter in stable phase is found to be 5.9495 Å. By the spin resolved density of states calculations, we have shown that the exchange splitting due to Mn atom is the main reason of ferromagnetic behavior of Cu{sub 2}MnGa. The absence of energy gap in both the spin channels predicts that the material is metallic. The total and partial density of states, elastic constants, Shear, Bulk and Young’s moduli, Zener isotropy factor, Cauchy pressure, Pugh's ductility, Kleinman parameter and Poisson's ratio are reported for the first time for the alloy. Cauchy's pressure and Pugh's index of ductility label Cu{sub 2}MnGa as ductile. Cu{sub 2}MnGa is found to be ferromagnetic and anisotropic in nature. The quasi-harmonic approximations have been employed to study the pressure and temperature dependent thermodynamic properties of Cu{sub 2}MnGa. - Highlights: • It is the first attempt to predict a variety of crystal properties of Cu{sub 2}MnGa. • Cu{sub 2}MnGa shows magnetism and hence can prove to be important in modern technology. • Cu{sub 2}MnGa is ductile and hence can attract attention of scientists and technologists.

    We studied clinical aspects and courses of patients with pulmonary radioactivity on liver scintigraphy and speculated the mechanism of pulmonary uptake of radiocolloids. Forty-nine patients with pulmonary radioactivity were classified into 5 diseases groups-liver disease, infection, cancer, ischemic necrosis of liver, etc.- and their presence of absence of chronic liver disease (CLD), Child-Pugh class, serum levels of AST and ALT, results of follow-up liver scintigraphy and clinical course were checked. Of total 49 patients 25 had CLD; there were 23 liver disease patients, 16 infection patients, 7 advanced cancer patients, 2 ischemic necrosis of liver patients, and 1 hemolytic anemia patient. Reversible rise of serum levels of AST and ALT was observed in all patients with liver disease and ischemic necrosis of liver; on one-way ANOVA, these rise were statistically significant (p<0.01). Serum level of ALT of liver disease group patients without CLD was significantly higher than that of infection group patients without CLD (p<0.05). Among 17 patients who underwent follow-up liver scintigraphy, 13 showed no pulmonary radioactivity. Total 12 patients died during follow-up and most of them were terminal cancer patients or CLD patients of Child-Pugh class C. Pulmonary radioactivity of radiocolloid liver scintigraphy could be attributed to the mobilization of reticuloendothelial system (RES) cells by the activation of RES cells in severe infection and terminal cancer, and also by the extensive liver desctruction in liver diseases

    The objective was to compare data obtained by color duplex-Doppler ultrasound (mean velocity, flow and portal vein congestion index) in patients with chronic diffuse liver disease with and without portal hypertension (PH) (demonstrated endoscopically) with that of a healthy control group. Over a two-year period, 50 studies were performed in 10 healthy subjects (control group) with a mean age of 36 years and in 40 chronic liver disease patients (study group with a mean age of 58 years), most of whom presented alcoholic liver cirrhosis and belonged to Child-Pugh class B. They were subdivided according to endoscopic study into patients without (group 1) and with (group 2) portal hypertension. There were statistically significant differences in the diameters of splenic vein, spleen, portal vein and in the portal Vm, which decreased as the Child-Pugh score rose. When the patients without (group 1) and with (group 2) endoscopic evidence of PH (esophageal varices)were analyzed and compared, the two groups presented no statistically significant differences with respect to portal Vm, blood flow out of the liver, presence of collateral vessels, or the portal vein congestion index; the latter was significantly different in both the study group as a whole and in the patients with PH when compared with the control group. Given that this report is based on a pilot study which requires a larger sample number, we are unable to arrive at definitive conclusions. (Author) 18 refs.

    Sarcopenia impairs survival in patients with hepatocellular carcinoma (HCC). This study aimed to clarify the factors that contribute to decreased skeletal muscle volume in patients with HCC. The third lumbar vertebra skeletal muscle index (L3 SMI) in 351 consecutive patients with HCC was calculated to identify sarcopenia. Sarcopenia was defined as an L3 SMI value ≤ 29.0 cm²/m² for women and ≤ 36.0 cm²/m² for men. The factors affecting L3 SMI were analyzed by multiple linear regression analysis and tree-based models. Of the 351 HCC patients, 33 were diagnosed as having sarcopenia and showed poor prognosis compared with non-sarcopenia patients ( p = 0.007). However, this significant difference disappeared after the adjustments for age, sex, Child-Pugh score, maximum tumor size, tumor number, and the degree of portal vein invasion by propensity score matching analysis. Multiple linear regression analysis showed that age ( p = 0.015) and sex ( p < 0.0001) were significantly correlated with a decrease in L3 SMI. Tree-based models revealed that sex (female) is the most significant factor that affects L3 SMI. In male patients, L3 SMI was decreased by aging, increased Child-Pugh score (≥56 years), and enlarged tumor size (<56 years). Maintaining liver functional reserve and early diagnosis and therapy for HCC are vital to prevent skeletal muscle depletion and improve the prognosis of patients with HCC.

    We wanted to analyze the causes of prolonged hospitalization (over 7 days) after transarterial chemoembolization (TACE) in patients with unresectable Hepatocellular Carcinoma and its related factors. We analyzed the total hospital days after patients with unresectable Hepatocellular Carcinoma received transarterial chemoembolization, and these patients were treated during the recent 6 month at our hospital. Two hundred twenty three sessions showed a short term hospital stay (less than 7 days) and 57 sessions showed a prolonged hospital stay (more than 7 days), so a total of 280 sessions were analyzed. The hospital stay less than seven days was set for the control group and this was correlated with the patient's age, gender, the level of bilirubin and albumin, the platelet counts, the AST/ALT ratio, the a-FT, the presence of portal vein thrombosis and ascites, several scoring systems (Child-Pugh, CLIP, and OKUDA score) and the need for additional embolization at the time of the procedure. Compared with that of the control group, ascites (p=0.004), portal vein thrombosis (p=0.000), a platelet count below the hundred thousand (p=0.012), a Child-Pugh score more than B (p=0.023), a CLIP score more than 2 (p=0.000) and a OKUDA score more than II (p=0.000) showed significant differences. The evaluation of patients' factors would be useful to predict extended post-procedural hospitalization after hepatic chemoembolisation

    Full Text Available ObjectiveTo investigate the clinical features of male patients with alcoholic liver cirrhosis (ALC or hepatitis B cirrhosis (HBC complicated by abnormal glucose metabolism. MethodsA total of 287 patients with liver cirrhosis who were admitted to Guangzhou Panyu Central Hospital from January 2008 to September 2013 were selected. Among these patients, 74 had ALC and were all male, including 54 with abnormal glucose metabolism; the other 213 had HBC, including 97 with abnormal glucose metabolism (69 male patients and 28 female patients. A controlled study was performed for the clinical data of ALC and HBC patients with abnormal glucose metabolism, to investigate the association of patients′ clinical manifestations with the indices for laboratory examination, insulin resistance index, incidence rate of abnormal glucose metabolism, and Child-Pugh class. The t-test was applied for comparison of continuous data between groups, the chi-square test was applied for comparison of categorical data between groups, and the Spearman rank correlation was applied for correlation analysis. ResultsCompared with HBC patients, ALC patients had significantly higher incidence rates of abnormal glucose metabolism (730% vs 32.4%, hepatogenous diabetes (35.1% vs 14.6%, fasting hypoglycemia (27.0% vs 10.3%, and impaired glucose tolerance (31.1% vs 14.1% (χ2=4.371, 3.274, 4.784, and 1.633, all P<0.05. The Spearman correlation analysis showed that in ALC and HBC patients, the incidence rate of abnormal glucose metabolism was positively correlated with Child-Pugh class (rs=0.41, P<005. Compared with the HBC patients with abnormal glucose metabolism, the ALC patients with abnormal glucose metabolism had a significantly higher incidence rate of Child-Pugh class A (χ2=7.520, P=0.001, and a significantly lower incidence rate of Child-Pugh class C (χ2=6.542, P=0.003.

    participate in this study. The patients were examined at least twice with 12 to 72 months (mean, 26 months) intervening. The annual changes were calculated from the parameters of GSA scintigraphy at baseline and at the time of final examination. Tc-99m GSA (185 MBq) was injected intravenously, and dynamic images were recorded with the patient supine under a gamma-camera with a large field of view and a low-energy multipurpose collimator with parallel holes (ZLC-3500, Shimadzu Corp., Kyoto, Japan). Computer acquisition of the gamma-camera data was started just before the injection of the Tc-99m GSA and was stopped 20 min later. Accumulation images in the anterior abdominal view were obtained for the first 20 min after the injection. Time-activity curves for the heart and liver were generated from ROI for the heart and liver. The receptor index was calculated by dividing the radioactivity of the liver ROI by that of the liver-plus-heart ROI at 15 min after the injection. The index of blood clearance was calculated by dividing the radioactivity of the heart ROI 15 min after injection by that of the heart ROI 3 min after injection. Results: In the cross-sectional study, the medians (25th and 75th percentiles) of the receptor index were 0.95 (0.93, 0.96) in the healthy subjects, 0.92 (0.89, 0.94) in patients with chronic hepatitis, 0.89 (0.86, 0.93) in cirrhotic patients in Child-Pugh stage A, 0.80 (0.76, 0.85) in cirrhotic patients in stage B, and 0.69 (0.61, 0.79) in cirrhotic patients in stage C. The differences in receptor index between healthy subjects and those in patients of each group were significant (all p<0.001). The medians (25th and 75th percentiles) of the index of blood clearance were 0.51 (0.43, 0.53) in the healthy subjects, 0.56 (0.51, 0.61) in patients with chronic hepatitis, 0.62 (0.55, 0.68) in cirrhotic patients in Child-Pugh stage A, 0.73 (0.68, 0.78) in cirrhotic patients in stage B, and 0.80 (0.74, 0.84) in cirrhotic patients in stage C.

    We report our institutional observations of ten patients with advanced hepatocellular carcinoma (HCC) (seven and three were Child-Pugh class A and B, respectively) who received compassionate regorafenib therapy between June 2016 and January 2017. These patients did not fit the rigid criteria of a clinical trial and represented the use of regorafenib in an everyday clinic situation. Regorafenib (160 mg P.O. daily) was administered to patients on a 4-week cycle (3 weeks on, 1 week off) until disease progression (assessed using mRECIST criteria) or discontinuation secondary to toxicity (assessed using CTCAE criteria). Relevant clinical data were abstracted from patient medical records and reviewed retrospectively. The median duration of patient treatment was 6.6 weeks, and the median time to disease progression was 12.5 weeks. Most common treatment emergent adverse events were fatigue, diarrhea, and hand-foot skin reaction. Elevated AST and ALT were the most commonly observed laboratory-assessed adverse events, which reached grade 3 status in the Child-Pugh class B patients only. We observed intolerance to regorafenib treatment in one patient who had previously received a liver transplant. We also saw lithium toxicity in one patient receiving long-term lithium treatment, suggesting a potential and unexpected drug-drug interaction with regorafenib. Taken together, our observations indicate that regorafenib is beneficial in the treatment of patients with advanced HCC who progressed on or demonstrated intolerance to sorafenib therapy; however, careful selection and close monitoring of patients is necessary to maximize the benefit while minimizing the toxicities of regorafenib treatment.

    To evaluate the safety and efficacy of Cyberknife stereotactic body radiation therapy (SBRT) and its effect on survival in patients with unresectable huge hepatocellular carcinoma (HCC) unsuitable of other standard treatment option. Between 2009 and 2011, 22 patients with unresectable huge HCC (≧10 cm) were treated with SBRT. dose ranged from 26 Gy to 40 Gy in five fractions. Overall survival (OS) and disease-progression free survival (DPFS) were determined by Kaplan-Meier analysis. Tumor response and toxicities were also assessed. After a median follow-up of 11.5 month (range 2–46 months). The objective response rate was achieved in 86.3% (complete response (CR): 22.7% and partial response (PR): 63.6%). The 1-yr. local control rate was 55.56%. The 1-year OS was 50% and median survival was 11 months (range 2–46 months). In univariate analysis, Child-Pugh stage (p = 0.0056) and SBRT dose (p = 0.0017) were significant factors for survival. However, in multivariate analysis, SBRT dose (p = 0.0072) was the most significant factor, while Child-Pugh stage of borderline significance. (p = 0.0514). Acute toxicities were mild and well tolerated. This study showed that SBRT can be delivered safely to huge HCC and achieved a substantial tumor regression and survival. The results suggest this technique should be considered a salvage treatment. However, local and regional recurrence remain the major cause of failure. Further studies of combination of SBRT and other treatment modalities may be reasonable

    Transcatheter arterial chemoembolization has been performed worldwide for patients with unresectable hepatocellular carcinoma for three decades. After long controversy, survival benefit was revealed by two randomized controlled trials. In Japan, chemoembolization accounted for initial treatment of 32% of patients and 58% for recurrent foci. The indications of chemoembolization are various: they are multinodular tumors in the Barcelona Clinic Liver Cancer staging system and two or three tumors >3 cm or four or more tumors in the Japanese guidelines, and both indications fulfill the Child-Pugh Class A/B or liver damage A/B and exclusion of vascular invasion or extrahepatic spread. Recently, both guidelines were identified to have almost similar content. The 4966 patients stratified to chemoembolization recommended by the Japanese guidelines showed that 3-year survival of patients with two or three tumors >3 cm or four or more tumors was 55 and 46% in Child-Pugh A, respectively, and 30 and 22% in Class B, respectively. These results would help in comparing the outcome of chemoembolization in the different backgrounds of the East and West. The modified Response Evaluation Criteria in Solid Tumor guideline is now proposed to cover the deficiency of Response Evaluation Criteria in Solid Tumor to evaluate the response to chemoembolization. Recently, chemoembolization with drug-eluting beads and radioembolization with yttrium-90 microspheres have been introduced, and each of them showed similar tumor response and median survival compared with conventional chemoembolization. Moreover, the combination of chemoembolization and molecular targeted agent is now on-going to evaluate the synergistic effect. (author)

    Full Text Available ObjectiveTo explore the correlation of spleen stiffness measured by FibroScan with esophageal and gastric varices in patients with liver cirrhosis. MethodsSpleen and liver stiffness was measured by FibroScan in 72 patients with liver cirrhosis who received gastroscopy in our hospital from December 2012 to December 2013. Categorical data were analyzed by χ2 test, and continuous data were analyzed by t test. Pearson's correlation analysis was used to investigate the correlation between the degree of esophageal varices and spleen stiffness. ResultsWith the increase in the Child-Pugh score in patients, the measurements of liver and spleen stiffness showed a rising trend. Correlation was found between the measurements of spleen and liver stiffness (r=0.367, P<0.05. The differences in measurements of spleen stiffness between patients with Child-Pugh classes A, B, and C were all significant (t=5.149, 7.231, and 6.119, respectively; P=0031, 0.025, and 0.037, respectively. The measurements of spleen and liver stiffness showed marked increases in patients with moderate and severe esophageal and gastric varices. The receiver operating characteristic (ROC curve analysis showed that the area under the ROC curve, sensitivity, and specificity for spleen stiffness were significantly higher than those for liver stiffness and platelet count/spleen thickness. ConclusionThe spleen stiffness measurement by FibroScan shows a good correlation with the esophageal and gastric varices in patients with liver cirrhosis. FibroScan is safe and noninvasive, and especially useful for those who are not suitable for gastroscopy.

    Aim: To retrospectively assess long-term survival benefit and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) patients with portal vein tumour thrombosis (PVTT), and to evaluate factors that significantly affect outcomes of these patients. Materials and methods: One hundred and thirty-four HCC patients (118 men and 16 women; mean age 54.8 years, range 26–79 years) with PVTT were retrospectively assessed. Patients were treated with TACE combined with RFA. Data analysed included patient demographics, liver volume, Child–Pugh score, and Cancer of the Liver Italian Programme (CLIP) score and imaging findings. Survival time (from occurrence of PVTT to last follow-up) was calculated using the Kaplan–Meier method, predictive factors and its correlation with survival was assessed using the multivariate Cox proportional hazards regression method. Results: The median overall survival (OS) time was 29.5 months (range 16.6–42.4 months), the 1, 3, and 5 year OS were 63%, 40%, and 23%. Cox hazards regression analysis revealed that functional remnant liver volume (FRLV), remnant liver volume (RLV)/total liver volume (TLV), radiation, tumour number, vascular endothelial growth factor (VEGF) distribution, and gross type were the only independent predictive factors of outcome (p = 0.039, 0.010, 0.009, 0.034, 0.031, and 0.000, respectively). Conclusion: TACE combined with RFA was found to be an effective therapy, FRLV and RLV/TLV have close correlation with survival for HCC patients with PVTT type I, II, or partial III and Child–Pugh A or B

    Alcoholic liver disease (ALD) is a major cause of mortality and morbidity worldwide. Various studies show contradictory results about the role of amount, type and duration of alcohol exposure in determining the risk to develop ALD with ethnic variations in susceptibility to develop ALD and South Asians are shown to be more prone to develop ALD. This study was carried out to evaluate clinical profile of ALD in Indian population and to find out the correlation of disease severity and outcome with alcohol intake. 201 patients of ALD were evaluated to correlate their clinical complications, biochemical parameters, prognostic markers (Discriminant function [DF] score, Model for end-stage liver disease [MELD] score and Child-Pugh score) and in-hospital mortality with their alcohol intake data in form of type, amount and duration of alcohol intake. Hepatic encephalopathy, neutrophil to lymphocyte ratio (NLR) and all three prognostic scores showed a dose-dependent relation with the amount of alcohol intake (p < 0.05). However, the mortality rate didn't show a significant relation with amount. Further the type of alcohol intake didn't show any relation with disease severity; however, the duration of alcohol intake showed a positive relation with mortality rate. NLR emerged as a useful bedside marker of disease severity which correlates well with all prognostic markers (p < 0.05 for NLR's Spearman correlation with DF score and Child-Pugh Score), more so with MELD score (p < 0.0001); and complications like hepatic encephalopathy and hepato-renal syndrome. NLR also correlated with mortality rate but it was not statistically significant.

    Full Text Available Surgery in cirrhotic patients is associated with high morbidity and mortality related to portal hypertension and liver insufficiency. Therefore, preoperative portal decompression is a logical approach to facilitate abdominal surgery and hopefully to improve postoperative survival. The present study evaluated the clinical outcomes of 18 patients (mean age 58 years with cirrhosis (seven alcoholics and 11 nonalcoholics who underwent transjugular intrahepatic portosystemic shunt (TIPS placement before antrectomy (n=5, colectomy (n=10, small-bowel resection (n=1, pancreatectomy (n=1 and nephrectomy (n=1. TIPS was performed a mean (± SD of 72±21 days before surgery and induced a marked mean decrease in portohepatic gradient from 21.4±3.9 mmHg to 8.4±3.4 mmHg. Cirrhotic patients (n=17 who underwent elective abdominal surgery without preoperative TIPS placement were used as the control group. Both groups were matched for age, etiology of cirrhosis, indications for surgery, type of surgery and coagulation parameters. The mean Pugh score was significantly higher in the TIPS group (7.7 versus 6.2. No significant differences were observed for operative blood loss, postoperative complications, duration of hospitalization and one-month (83% versus 88% or one-year (54% versus 63% cumulative survival rate. Analysis using the Cox proportional hazards model showed that neither TIPS placement nor preoperative Pugh score were independent predictors for survival. The present study suggests that preoperative TIPS placement does not improve postoperative evolution after abdominal surgery in cirrhotic patients with good or moderately impaired liver function.

    The elastic and thermodynamic properties of ZnSe are investigated using thermo_pw package implemented in Quantum espresso code within the framework of density functional theory. The pseudopotential method within the local density approximation is used for the exchange-correlation potential. The physical parameters of ZnSe bulk modulus and shear modulus, anisotropy factor, Young's modulus, Poisson's ratio, Pugh's ratio and Frantsevich's ratio are calculated. The sound velocity and Debye temperature are obtained from elastic constant calculations. The Helmholtz free energy and internal energy of ZnSe are also calculated. The results are compared with available theoretical calculations and experimental data.

    El 27 de Agosto de 1995, Vernon Pugh, presidente de la comisión de la International Rugby Board (IRB) para el amateurismo, declaró que el Rugby pasaba a ser un deporte libre. Se terminaba de esta forma con más de un siglo de amateurismo declarado en este deporte, y se terminaba también con una década de debates sobre el conocido shamateurismo, o profesionalismo encubierto, en el cual los jugadores no cobraban por jugar pero si por el trabajo, ya fuera real o ficticio, que le proporciona el cl...

    , but they are all still at an immature technology level, as no substantial experience from full-scale detailed design exists. By employing a functional failure mode and effects analysis (F-FMEA) with a decision making tool (Pugh Matrix), the paper presents a structured set of functionalities and design drivers...... required from the turbine DC converter and uses these to compare 6 distinct candidate circuit topologies. The end goal is not to select the best topology, but to narrow down from a vast list of options and give a method that will increase confidence and guide towards the characteristics of reliable design....

    Accumulating evidence indicates that components of the systemic inflammatory response, such as C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), have been associated with prognosis of various cancers. We aimed to elucidate whether CRP and NLR could serve as potential surrogate markers for response and survival in patients with hepatocellular carcinoma (HCC). The study population consisted of 318 consecutive patients with HCC. CRP and NLR were measured at baseline with follow-up measurements. With the mean follow-up of 13.9 months, the median survival time was 13.8 months. Child-Pugh class, tumor size > 5 cm, tumor multiplicity, presence of portal vein thrombosis, α-fetoprotein > 200 ng/mL, CRP > 6.3 mg/L and NLR > 2.3 were identified as independent factors for worse survival of HCC (all p < 0.05). Patients with elevated CRP (> 6.3 mg/L) and elevated NLR (> 2.3) had a significantly shorter overall survival than those with low CRP and low NLR (all p < 0.001). The combined use of CRP and NLR provided incremental prognostic information. With significant inter-correlations, levels of CRP and NLR escalated with aggravating Child-Pugh class from A to C or progressing tumor stage from I to IV. CRP and NLR on baseline and serial measurements were well predictive of treatment response (p < 0.001). CRP and NLR are independent indicators for survival in HCC patients, reflecting tumor burden and hepatic reserve. Their role in predicting tumor response and survival is more enhanced when used in combination. This study suggests that CRP and NLR are important prognostic biomarkers for HCC

    Full Text Available ObjectiveTo investigate the possible risk factors for rebleeding after splenectomy and pericardial devascularization in the treatment of portal hypertension due to liver cirrhosis, and to provide a certain basis for reducing the incidence of digestive tract re-hemorrhage for these patients. MethodsA retrospective analysis was performed on 238 cirrhotic patients with portal hypertension who underwent splenectomy and pericardial devascularization in the First Hospital of Lanzhou University from December 2003 to December 2013. These patients were divided into postoperative rebleeding group (n=32 and non-bleeding group (n=206. Univariate analysis (t test or chi-square test and multivariate logistic regression analysis were performed to investigate the risk factors for rebleeding after splenectomy and pericardial devascularization. ResultsOf the 32 patients with postoperative rebleeding, 17 had esophagogastric variceal bleeding, 11 had bleeding due to portal hypertensive gastropathy, and 4 had stress ulcer bleeding. The univariate analysis showed that there were significant differences between the two groups in the following factors: Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, pathological changes of the gastric mucosa, platelet count, prothrombin time (PT, activated partial thromboplastin time (APTT, and presence of diabetes (all P<0.05. The multivariate logistic regression analysis suggested that the significant independent influential factors for postoperative rebleeding were presence of diabetes, Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, diffuse lesion of the gastric mucosa, PT, and APTT. ConclusionFor cirrhotic patients with portal hypertension, the appropriate methods for managing these risk factors are of great clinical significance for preventing rebleeding after splenectomy and pericardial devascularization.

    Iron overload is an increasingly recognized phenomenon in nonhemochromatosis cirrhosis. To evaluate the relationship between iron overload and liver insufficiency and portal hypertension. Cirrhotics with hepatic hemodynamic and ferritin measurement (within 30 d) were included. Exclusion criteria were malignancy (except hepatocellular carcinoma Milan-in), severe chronic obstructive pulmonary disease, acute events in the previous 2 weeks, immunosuppression, transjugular intrahepatic portosystemic shunt or portal vein thrombosis, and end-stage renal disease. Patients were followed-up until death or liver transplant. Univariate and multivariate analysis were used. Fifty-one patients were included (male 61%; median age 57 y; interquartile range, 47 to 66 y); Child-Pugh A 11/B 25/C 15). A positive correlation was observed between ferritin and markers of inflammation (C-reactive protein: r=0.273, P=0.06 and aspartate aminotransferase: r=0.302, P=0.035). No correlation between ferritin and hepatic venous pressure gradient was seen. Negative correlations were observed between ferritin and circulatory dysfunction (mean arterial pressure: r=-0.360, P=0.014 and serum sodium: r=-0.419, P=0.002). In contrast, associations to markers of liver failure such as international normalized ratio (r=0.333, P=0.005), bilirubin (r=0.378, P=0.007), albumin (r=-0.265, P=0.082), model for end-stage liver disease (r=0.293, P=0.041), and Child-Pugh score (r=0.392, P=0.009) were observed. No differences in survival according to ferritin was detected. In patients with cirrhosis, serum ferritin levels are associated with markers of liver insufficiency, inflammation, and circulatory dysfunction but not portal hypertension.

    Purpose: To explore changes in functional connectivity and topological organization of brain functional networks in cirrhotic patients with minimal hepatic encephalopathy (MHE) and non hepatic encephalopathy (nonHE) and their relationship with clinical markers. Materials and methods: Resting-state functional MR imaging was acquired in 22 MHE, 29 nonHE patients and 33 healthy controls. Functional connectivity networks were obtained by computing temporal correlations between any pairs of 90 cortical and subcortical regions. Graph analysis measures were quantitatively assessed for each subject. One-way analysis of covariance was applied to identify statistical differences of functional connectivity and network parameters among three groups. Correlations between clinical markers, such as Child–Pugh scores, venous blood ammonia level, and number connection test type A (NCT-A)/digit symbol test (DST) scores, and connectivity/graph metrics were calculated. Results: Thirty functional connectivities represented by edges were found to be abnormal (P < 0.05, FDR corrected) in cirrhotic patients, in which 16 edges (53.3%) were related with sub-cortical regions. MHE patients showed abnormal small-world attributes in the functional connectivity networks. Cirrhotic patients had significantly reduced nodal degree in 8 cortical regions and increased nodal centrality in 3 cortical regions. Twenty edges were correlated with either NCT-A or DST scores, in which 13 edges were related with sub-cortical regions. No correlation was found between Child–Pugh scores and graph theoretical measures in cirrhotic patients. Conclusion: Disturbances of brain functional connectivity and small world property loss are associated with neurocognitive impairment of cirrhotic patients. Reorganization of brain network occurred during disease progression from nonHE to MHE.

    To evaluate the short-term outcome of plug-assisted retrograde transvenous obliteration (PARTO) using vascular plugs and gelatin sponges in comparison with balloon-occluded retrograde transvenous obliteration (BRTO) for the management of gastric varices. From January 2005 to October 2014, 171 patients were referred for management of gastric varices, of which, 52 patients with hemodynamically stable gastric varices (48 recent bleeding; 4 primary prophylaxes) were evaluated. Of these, 38 received BRTO (men/women 23/15; mean age 61.3; Child-Pugh classes A/B/C = 11/25/2) and 14 underwent PARTO (men/women 11/3; mean age 63.4; Child-Pugh classes A/B/C = 9/4/1). The technical success rate, complications, variceal changes, liver function, and exacerbation of ascites/pleural effusion were compared between the 2 groups within 3 months after the procedure. The technical success rates were 92.1% in the BRTO and 100% in the PARTO group. Procedure-related early complications occurred in the BRTO group alone (8%, n = 3). Among patients with technical success, follow-up CT at 1 month was available for 98% (n = 48/49). Complete thrombosis of gastric varices was achieved in 97.1% in the BRTO and 100% in the PARTO group. Worsening of esophageal varices was observed in 24% of the BRTO group alone (n = 8). The albumin level increased significantly in both groups and aspartate aminotransferase/alanine aminotransferase level improved significantly in the PARTO group (p < 0.05). Exacerbation of ascites/pleural effusion was observed in both groups (35.2% vs. 21.4%, both p > 0.05). PARTO appears to be equivalent to BRTO for short-term management of gastric varices

    Full Text Available Background: Patients with liver cirrhosis have high surgical risks due to malnutrition, impaired immunity, coagulopathy, and encephalopathy. However, there is no information in English literature about the results of liver cirrhotic patients who underwent instrumented lumbar surgery. The purpose of this study is to report the perioperative complications, clinical outcomes and determine the surgical risk factors in cirrhotic patients. Methods: We retrospectively reviewed 29 patients with liver cirrhosis who underwent instrumented lumbar surgery between 1997 and 2009. The hepatic functional reserves of the patients were recorded according to the Child-Turcotte-Pugh scoring system. Besides, fourteen other variables and perioperative complications were also collected. To determine the risks, we divided the patients into two groups according to whether or not perioperative complications developed. Results: Of the 29 patients, 22 (76% belonged to Child class A and 7 (24% belonged to Child class B. Twelve patients developed one or more complications. Patients with Child class B carried a significantly higher incidence of complications than those with Child class A (p = 0.011. In the Child class A group, patients with 6 points had a significantly higher incidence of complications than those with 5 points (p = 0.025. A low level of albumin was significantly associated with higher risk, and a similar trend was also noted for the presence of ascites although statistical difference was not reached. Conclusion: The study concludes that patients with liver cirrhosis who have undergone instrumented lumbar surgery carry a high risk of developing perioperative complications, especially in those with a Child-Turcotte-Pugh score of 6 or more.

    We evaluate the long-term prognosis and prognostic factors in patients treated with transarterial infusion chemotherapy using cisplatin-lipiodol (CDDP/LPD) suspension with or without embolization for unresectable hepatocellular carcinoma (HCC). Study subjects were 107 patients with HCC treated with repeated transarterial infusion chemotherapy alone using CDDP/LPD (adjusted as CDDP 10mg/LPD 1ml). The median number of transarterial infusion procedures was two (range, one to nine), the mean dose of CDDP per transarterial infusion chemotherapy session was 30 mg (range, 5.0-67.5 mg), and the median total dose of transarterial infusion chemotherapy per patient was 60 mg (range, 10-390 mg). Survival rates were 86% at 1 year, 40% at 3 years, 20% at 5 years, and 16% at 7 years. For patients with >90% LPD accumulation after the first transarterial infusion chemotherapy, rates were 98% at 1 year, 60% at 3 years, and 22% at 5 years. Multivariate analysis identified >90% LPD accumulation after the first transarterial infusion chemotherapy (p = 0.001), absence of portal vein tumor thrombosis (PVTT; p < 0.001), and Child-Pugh class A (p = 0.012) as independent determinants of survival. Anaphylactic shock was observed in two patients, at the fifth transarterial infusion chemotherapy session in one and the ninth in the other. In conclusion, transarterial infusion chemotherapy with CDDP/LPD appears to be a useful treatment option for patients with unresectable HCC without PVTT and in Child-Pugh class A. LPD accumulation after the first transarterial infusion chemotherapy is an important prognostic factor. Careful consideration should be given to the possibility of anaphylactic shock upon repeat infusion with CDDP/LPD.

    Liver transplant recipients are at an increased risk for liver failure when infected with hepatitis A virus (HAV) and hepatitis B virus (HBV). Therefore, it is important to vaccinate these individuals. The aim of the study was to evaluate how well liver transplanted patients in our unit were protected against HAV and HBV infection. Furthermore we investigated the vaccination rate and the antibody response to vaccination in these liver transplanted patients. Patients liver transplanted from January 2007 until August 2010 with a posttransplant check-up during the period March-November 2010 were included (n = 51). Information considering diagnose, date of transplantation, Child-Pugh score, and vaccination were collected from the patient records. Anti-HAV IgG and anti-HBs titers in serum samples were analyzed and protective levels were registered. Of the patients 45% were protected against hepatitis A infection and 29% against hepatitis B infection after transplantation. Only 26% were vaccinated according to a complete vaccination schedule and these patients had a vaccine response for HAV and HBV of 50% and 31%, respectively. An additional 31% received ≥ 1 doses of vaccine, but not a complete vaccination and the vaccine response was much lower among these patients, stressing the importance of completing the vaccination schedule. Even when patients were fully vaccinated, they did not respond to the same degree as healthy individuals. Patients seemed to be more likely to respond to a vaccination if they had a lower Child-Pugh score, suggesting that patients should be vaccinated as early as possible in the course of their liver disease.

    Unresectable hepatocellular carcinoma is extremely difficult to treat. TheraSphere consists of yttrium-90 (a pure beta emitter) microspheres, which are injected into the hepatic arteries. This article reviews the safety and survival of patients with hepatocellular carcinoma who were treated with yttrium-90 microspheres. Eighty patients were selected from a database of 108 yttrium-90 microsphere-treated patients and were staged by using Child-Pugh, Okuda, and Cancer of the Liver Italian Program scoring systems. Patients were treated with local, regional, and whole-liver approaches. Survival from first treatment was analyzed with Kaplan-Meier and Cox regression methods. Adverse events and complications of treatment were coded by using the Southwest Oncology Group toxicity scoring system. Patients received liver doses ranging from 47 to 270 Gy. Thirty-two patients (40%) received more than 1 treatment. Survival correlated with pretreatment Cancer of the Liver Italian Program scores ( P = .002), as well as with the individual Cancer of the Liver Italian Program components, Child-Pugh class, alpha-fetoprotein levels, and percentage of tumor replacement. Patients classified as Okuda stage I (n = 54) and II (n = 26) had median survival durations and 1-year survival rates of 628 days and 63%, and 384 days and 51%, respectively ( P = .02). One patient died of liver failure judged as possibly related to treatment. Thus, in selected patients with hepatocellular carcinoma, yttrium-90 microsphere treatment is safe and well tolerated. On the basis of these results, a randomized controlled trial is warranted comparing yttrium-90 microsphere treatment with transarterial chemoembolization by using the Cancer of the Liver Italian Program system for prospective stratified randomization.

    Hepatitis C is the most common health problem worldwide and is major cause of death due to proliferation of hepatocellular carcinoma. The medicines available for HCV treatment overcome up-to 95% complications of HCV. However, liver cancer needs some additional care. Normally Sorafenib tosylate 200 mg is recommended for liver cancer. There is no such trial in which this drug could effectively be used in combination of direct acting antivirals for HCV. The study was conducted for HCV patients (n=30) with liver cancer having decompensated stage. Combination of Sorafenib tosylate, Ribavirn and Sofosbuvir were used for the pharmacokinetics of these medicines. Child pugh score less then 7 (CP A) in adults during treatment phase (received 12 weeks of Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir 400 mg once daily) have no side effect while child pugh score 7-9 (CP B) have evidence of hypertension. The main efficiency end point sustained virology response with overcoming liver cancer as well in 12 weeks after end treatment (SVR-LLC 12). Mean pharmacokinetic exposure to Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir at week 8th was 2.1, 1.5,1.2 times greater in CP B than in CP A. Adverse effects (AEs) were observed in 12 out of 30 patients but not severe as lethal for life. Treatment with Sorafenib tosylate, Ribavirn and Sofosbuvir for twelve weeks was harmless and well accepted, 100 % patients achieve (SVR LLC 12) with 10-fold cure rate more than previous ones. The combination therapy of Sorafenib tosylate, Ribavirn and Sofosbuvir was found helpful for the management of decompensated liver cancer.

Among patients with technical success, follow-up CT at 1 month was available for 98% (n = 48/49). Complete thrombosis of gastric varices was achieved in 97.1% in the BRTO and 100% in the PARTO group. Worsening of esophageal varices was observed in 24% of the BRTO group alone (n = 8). The albumin level increased significantly in both groups and aspartate aminotransferase/alanine aminotransferase level improved significantly in the PARTO group (p < 0.05). Exacerbation of ascites/pleural effusion was observed in both groups (35.2% vs. 21.4%, both p > 0.05). PARTO appears to be equivalent to BRTO for short-term management of gastric varices.

    In order to identify key physical factor controlling the deformation and fracture behavior of bulk metallic glasses (BMGs), we compiled and analyzed the elastic moduli and compressive ductility for BMGs. In addition, new modulus data were generated in the critical ranges in order to facilitate the analysis. We have found that the intrinsic ductility of BMGs can be correlated with the bulk-to-shear modulus ratio B/G according to Pugh's [Philos. Mag. 45, 823 (1954) ] rule. In some individual BMG systems, for example, Fe based, the relationship seems to be very clear. The physical meaning of this correlation is discussed in terms of atomic bonding and connectivity.

    Algesia and inflammation are related with several pathological conditions. It is known that many drugs available for the treatment of these problems cause unwanted side effects. This study was aimed at evaluating acute toxicity and anti-inflammatory activity of Lampaya medicinalis Phil. (Verbenaceae) widely used in the folk medicine of Northern Chile against rheumatism, arthritis and body joints pain. Oral administration of hydroalcoholic extract (HAE) at the highest dose of 3000 mg/ Kg body weight resulted in no mortalities or evidence of significant behavioral changes. Histological examination revealed normal architecture and no significant adverse effects were observed on the liver, kidney, heart, lung or ovaries and testicles. The results suggest that the oral administration of hydroalcoholic extract (HAE) from Lampaya medicinalis did not produce any toxic effect in rats. Hydroalcoholic extract (HAE) significantly inhibited the carrageenan-induced rat paw edema in dose - response relationship, at test doses of 37.5, 75, 150 and 300 mg/Kg body weight. Maximum inhibition (61.98 ± 2.69%) was noted at 300 mg/Kg after 2 h of drug treatment carrageenan induced paw edema, whereas indomethacin produced 47.90 ± 1.16% of inhibition. The inhibitory values of edema at 3 h postcarrageenan were 31.04 ± 0.75%, 40.51 ± 2.36%, 48.97 ± 1.14% and 56.87 ± 0.41% for 37.5, 75, 150, and 300 mg/kg of extract respectively. Indomethacin (10 mg/Kg) gave a percentage inhibition of 49.44 ± 1.44. HAE (300 and 150 mg/kg) induced an anti-inflammatory effect greater than (or comparable) with the effect of indomethacin from 2nd to 4th hours of the experiment. Our results reveal for first time that compounds contained in the hydroalcoholic extract of Lampaya medicinalis Phil exert anti-inflammatory effect and the oral administration is safe and non toxic up to dose level 3000 mg/kg body weight. The anti-inflammatory activity may be associated with the presence of flavonoids. These

    Hepatic transit times measured by the contrast enhanced ultrasonography and liver elasticity were found to predict a clinically significant portal hypertension. However, these modalities we not yet sufficiently evaluated in predicting adverse clinical outcome in patients with clinically diagnosed cirrhosis (D´Amico stages > 1), having a clinically significant portal hypertension. The aim of our study was to assess the predictive power of the liver transit times and the liver elasticity on an adverse clinical outcome of clinically diagnosed cirrhosis compared with the MELD score. The study group included 48 consecutive outpatients with cirrhosis in the 2., 3. and 4. DAmico stages. Patients with stage 4 could have jaundice, patients with other complications of portal hypertension were excluded. Transit times were measured from the time of intravenous administration of contrast agent (Sonovue) to a signal appearance in a hepatic vein (hepatic vein arrival time, HVAT) or time difference between the contrast signal in the hepatic artery and hepatic vein (hepatic transit time, HTT) in seconds. Elasticity was measured using the transient elastography (Fibroscan). The transit times and elasticity were measured at baseline and patients were followed for up for 1 year. Adverse outcome of cirrhosis was defined as the appearance of clinically apparent ascites and/or hospitalization for liver disease and/or death within 1 year. The mean age was 61 years, with female/male ratio 23/25. At baseline, the median Child-Pugh score was 5 (IQR 5.0-6.0), MELD 9.5 (IQR 7.6 to 12.1), median HVAT was 22 s (IQR 19-25) and HTT 6 (IQR 5-9). HTT and HVAT negatively correlated with Child-Pugh (-0.351 and -0.441, p = 0.002) and MELD (-0.479 and -0.388, p = 0.006) scores. The adverse outcome at 1-year was observed in 11 cases (22.9 %), including 6 deaths and 5 hospitalizations. Median HVAT in those with/without the adverse outcome was 20 seconds (IQR 19.3-23.5) compared with 22 s (IQR 19-26, p

    To treated with electrochemotherapy (ECT) a prospective case series of patients with liver cirrhosis and Vp3-Vp4- portal vein tumor thrombus (PVTT) from hepatocellular carcinoma (HCC), in order to evaluate the feasibility, safety and efficacy of this new non thermal ablative technique in those patients. Six patients (5 males and 1 female), aged 61-85 years (mean age, 70 years), four in Child-Pugh A and two in Child-Pugh B class, entered our study series. All patients were studied with three-phase computed tomography (CT), contrast enhanced ultrasound (CEUS) and ultrasound-guided percutaneous biopsy of the thrombus before ECT. All patients underwent ECT treatment (Cliniporator Vitae ® , IGEA SpA, Carpi, Modena, Italy) of Vp3-Vp4 PVTT in a single session. At the end of the procedure a post-treatment biopsy of the thrombus was performed. Scheduled follow-up in all patients entailed: CEUS within 24 h after treatment; triphasic contrast-enhanced CT and CEUS at 3 mo after treatment and every six months thereafter. Post-treatment CEUS showed complete absence of enhancement of the treated thrombus in all cases. Post-treatment biopsy showed apoptosis and necrosis of tumor cells in all cases. The follow-up ranged from 9 to 20 mo (median, 14 mo). In 2 patients, the follow-up CT and CEUS demonstrated complete patency of the treated portal vein. Other 3 patients showed a persistent avascular non-tumoral shrinked thrombus at CEUS and CT during follow-up. No local recurrence was observed at follow-up CT and CEUS in 5/6 patients. One patient was lost to follow-up because of death from gastrointestinal hemorrage 5 wk after ECT. In patients with cirrhosis, ECT seems effective and safe for curative treatment of Vp3-Vp4 PVTT from HCC.

    Several treatments have been proven to be effective for variceal bleeding in patients with cirrhosis. The aim of this multicenter, prospective, cohort study was to assess how these treatments are used in clinical practice and what are the posttherapeutic prognosis and prognostic indicators of upper digestive bleeding in patients with cirrhosis. A training set of 291 and a test set of 174 bleeding cirrhotic patients were included. Treatment was according to the preferences of each center and the follow-up period was 6 weeks. Predictive rules for 5-day failure (uncontrolled bleeding, rebleeding, or death) and 6-week mortality were developed by the logistic model in the training set and validated in the test set. Initial treatment controlled bleeding in 90% of patients, including vasoactive drugs in 27%, endoscopic therapy in 10%, combined (endoscopic and vasoactive) in 45%, balloon tamponade alone in 1%, and none in 17%. The 5-day failure rate was 13%, 6-week rebleeding was 17%, and mortality was 20%. Corresponding findings for variceal versus nonvariceal bleeding were 15% versus 7% (P =.034), 19% versus 10% (P =.019), and 20% versus 15% (P =.22). Active bleeding on endoscopy, hematocrit levels, aminotransferase levels, Child-Pugh class, and portal vein thrombosis were significant predictors of 5-day failure; alcohol-induced etiology, bilirubin, albumin, encephalopathy, and hepatocarcinoma were predictors of 6-week mortality. Prognostic reassessment including blood transfusions improved the predictive accuracy. All the developed prognostic models were superior to the Child-Pugh score. In conclusion, prognosis of digestive bleeding in cirrhosis has much improved over the past 2 decades. Initial treatment stops bleeding in 90% of patients. Accurate predictive rules are provided for early recognition of high-risk patients.

    Aim: To evaluate the authors' experience with interventional radiological management of tumour rupture in hepatocellular carcinoma (HCC) in a Western population. Materials and methods: A retrospective review was performed of all consecutive patients treated at a single institution with transcatheter embolisation for ruptured HCC between 2000 and 2013. Patient age, sex, aetiology of liver disease, degree of underlying liver dysfunction, and clinical presentation were assessed. Embolisation was performed in a selective fashion when possible. Success, complications, and survival were assessed. Results: Twenty-three patients were treated with embolisation for ruptured HCC. Of these patients, nine, nine, and five patients were Child–Pugh Class A, B, and C respectively. Embolisation was successful in 22 patients; one patient remained haemodynamically unstable and transfusion dependent despite embolisation. No major complications occurred. Median survival time was 260 days and the 30 day and 1 year survival rates were 83% and 45%, respectively. Child–Pugh class B or C (p = 0.04), Model for End-Stage Liver Disease score greater than 10 (p = 0.04), lobar embolisation (p = 0.04), and presence of portal vein thrombosis (p = 0.01) were significantly associated with worse prognosis. Conclusion: Transcatheter embolisation is effective at controlling haemorrhage in patients with ruptured HCC. Although major procedural complications are low, embolisation should proceed with an understanding of poor prognosis in patients with decompensated liver disease. Superselective embolisation is associated with improved prognosis and should be performed when feasible. -- Highlights: •We reviewed our outcomes after transcatheter embolization of ruptured HCC in a western population. •Overall survival in the setting of ruptured HCC remains poor despite successful embolization. •Worse liver function, portal vein thrombosis, and lobar embolization were all associated with

    AIM: To investigate the association between endogenous hydrogen sulfide (H2S) and portal hypertension as well as its effect on vascular smooth muscle cells. METHODS: Portal hypertension patients were categorized by Child-Pugh score based on bilirubin and albumin levels, prothrombin time, ascites and hepatic encephalopathy. Plasma H2S concentrations and portal vein diameters (PVDs) were compared between portal hypertension patients and control participants, as well as between portal hypertension patients with varying degrees of severity. In addition, we established a rabbit hepatic schistosomiasis portal hypertension (SPH) model and analyzed liver morphology, fibrosis grade, plasma and liver tissue H2S concentrations, as well as cystathionine γ-lyase (CSE) activity and phosphorylated extracellular signal-regulated kinase (pERK)1/2, B cell lymphoma (Bcl)-2 and Bcl-XL expression in portal vein smooth muscle cells, in addition to their H2S-induced apoptosis rates. RESULTS: In portal hypertension patients, endogenous H2S levels were significantly lower than those in healthy controls. The more severe the disease was, the lower were the H2S plasma levels, which were inversely correlated with PVD and Child-Pugh score. Liver tissue H2S concentrations and CSE expression were significantly lower in the SPH rabbit livers compared with the control animals, starting at 3 wk, whereas pERK 1/2 expressions gradually increased 12-20 wk after SPH model establishment. In portal vein smooth muscle cells, increasing H2S levels led to increased apoptosis, while Bcl-2 and Bcl-XL expression decreased. CONCLUSION: H2S prevents vascular restructuring caused by excessive proliferation of smooth muscle cells via apoptosis induction, which helps to maintain normal vascular structures. PMID:24574782

    To evaluate patterns of recurrence and factors which influence them in radiofreqency (RF) ablation for the treatment of hepatocellular carcinoma (HCC). Between May 1999 and March 2000, 69 patients with 82 HCCs underwent RF ablation for complete necrosis. They were diagnosed by tissue biopsy or tumor marker, and the results of triphasic spiral CT. The indications were that nodular lesions were clearly visualized at sonography, less than 5 cm in size and less than four in number, and that patients had no history of previous treatment. Local therapeutic efficacy such as complete necrosis and marginal recurrence, and new lesions were evaluated by means of triphasic spiral CT performed at least six months after the completion of ablation. We then analyzed the correlation between local therapeutic efficacy and various influential factors such as tumor size, whether the tumor was attached to the portal vein, gross morphology, Child-Pugh classification, and {alpha}-fetoprotein level vefore the procedure, as well as the correlation between new lesions and influential factors which included the {alpha}-fetoprotein level before the procedure, Child-Pugh classification, and multiplicity per person. During a mean follow-up period of 8.95 (range, 6-14) months after RF ablation, the rate of complete necrosis and of marginal recurrence was 91% and 12%, respectively. When a tumor was larger and was attached to a large branch of the portal vien, the incidence of incomplete necrosis and marginal recurrence was greater. The occurrence rate of new lesion was 19.4%. When the {alpha}-fetoprotein level before the procedure was higher and a tumor was multiple in number, new lesions occurred more frequently. Sufficient knowledge of patterns of recurrence and the factors which influence them might improve the therapeutic effects of RF ablation in patients with HCC.

    Hepatic encephalopathy (HE) influences short-term and long-term prognoses. Recently, glycerol phenylbutyrate (PB), that lowers ammonia by providing an alternate pathway to urea for waste nitrogen excretion, has shown that it was effective in preventing the occurrence of HE in RCT. The aim was to assess the benefits of sodium PB in cirrhotic patients admitted to ICU for overt HE, in terms of ammonia levels decrease, neurological improvement, and survival. Cirrhotic patients who presented with overt HE, ammonia levels >100 μmol/L, and did not display any contra-indication were included. Sodium PB was administered at 200 mg/kg/day. Control group included historical controls treated by standard therapy, matched for age, sex, MELD score, and severity of HE. Eighteen patients were included and treated with sodium PB (age: 59 [45-68], male gender: 15 [83%], Child-Pugh B: 8 [44%], Child-Pugh C: 10 [56%], and MELD score: 16 [13-23]). Ammonia levels significantly decreased in the PB as compared to the control group from inclusion to 12 h and from inclusion to 48 h (P = 0.0201 and P = 0.0230, respectively). The proportion of patients displaying neurological improvement was only higher in the PB-treated group as compared to controls at ICU discharge (15 [83%] vs. 9 [50%], P = 0.0339). ICU discharge survival was significantly higher in patients treated with PB (17 [94%] vs. 9 [50%], P = 0.0017). In cirrhotic patients with overt HE, sodium PB could be effective in reducing ammonia levels and might be effective in improving neurological status and ICU discharge survival. More extensive data, especially a RCT, are mandatory. © 2017 Société Française de Pharmacologie et de Thérapeutique.

    Full Text Available Abstract Background Hepatic encephalopathy has a negative impact on health-related quality of life (QoL in liver cirrhosis. There are scarce and conflicting data on whether type or etiology of liver cirrhosis could be related to hepatic encephalopathy in patients with cirrhosis. We aimed to determine the impact of cirrhosis etiology on hepatic encephalopathy and whether hepatic encephalopathy affects health-related QoL among patients with cirrhosis of different etiologies. Methods A total of 156 cirrhotic patients were prospectively evaluated for the presence of hepatic encephalopathy according to the West-Haven criteria as well as by means of two psychometric tests. Patients with cryptogenic cirrhosis or cirrhosis due to mixed hepatocellular/cholestatic etiologies were excluded. Fasting plasma glucose levels were also measured. QoL was evaluated by means of a validated questionnaire (SF-36. Results Diabetes mellitus was more common in patients with hepatocellular cirrhosis compared to those with cholestatic cirrhosis but the two groups did not differ in cirrhosis severity or the prevalence of hepatic encephalopathy (p > 0.05. The groups of patients with cirrhosis due to alcohol, hepatitis C, or cholestatic liver disease did not differ in severity of liver cirrhosis or the prevalence of hepatic encephalopathy (p > 0.05. Patients with cirrhosis of different etiologies did not differ in any SF-36 domain (p > 0.05. In multivariate analysis, performance at neuropsychological testing was independently related only to age, diabetes mellitus, and the Child-Pugh score whereas the SF-36 physical component summary only to the Child-Pugh score and hepatic encephalopathy. Conclusion Cirrhosis etiology does not seem to be related to hepatic encephalopathy or health-related QoL. Cognitive impairment is associated mainly with age, liver disease severity and diabetes mellitus.

    Full Text Available Background/Aim. Liver cirrhosis is a chronic, progressive disease and it is usually accompanied by portal hypertension. The development of oesophageal varices (OV is one of the major complications of portal hypertension. Cirrhotic patients should be screened for the presence of OV when portal hypertension is diagnosed. In order to reduce the increasing burden that endoscopy units have to bear, some studies have attempted to identify parameters for noninvasive prediction of OV presence. The aim of our study was to evaluate the value of biochemical and ultrasonography parameters for prediction of OV presence. Methods. This study included 58 cirrhotic patients who underwent a complete biochemical workup, ultrasonography examination and upper digestive endoscopy. Right liver lobe diameter/albumin ratio was calculated and its correlation to the presence and degree of OV, and Child-Pugh score of liver cirrhosis explored. Results. The mean age of the patients included in the study was 53.07±13.09 years; 40 were males and 18 females. In the Child-Pugh class A were 53.4% patients, class B 39.7%, whereas 6.9% were in the class C. In 24.1% of the patients no OV were identified by upper digestive endoscopy, 19% had OV grade I, 34.5% grade II, 20.7% grade III, and 1.7% OV grade IV. The mean value of the right liver lobe diameter/ albumin ratio was 5.43±1.79 (range of 2.76−11.44. Statistically significant correlation (p < 0.01 was confirm by Spearman's test between OV grade and calculated index (ρ = 0.441. Conclusion. The right liver lobe diameter/albumin ratio is a noninvasive parameter which provides an accurate information pertinent to the determination of OV presence and their grading in patients with liver cirrhosis. .

    To assess the feasibility of balloon-occluded retrograde transvenous obliteration (BRTO) in active gastric variceal bleeding, and to compare the findings with those of transjugular intrahepatic portosystemic shunt (TIPS). Twenty-one patients with active gastric variceal bleeding due to liver cirrhosis were referred for radiological intervention. In 15 patients, contrast-enhanced CT scans demonstrated gastrorenal shunt, and the remaining six (Group 1) underwent TIPS. Seven of the 15 with gastrorenal shunt (Group 2) were also treated with TIPS, and the other eight (Group 3) underwent BRTO. All patients were followed up for 6 to 21 (mean, 14.4) months. For statistical inter-group comparison of immediate hemostasis, rebleeding and encephalopathy, Fisher's exact test was used. Changes in the Child-Pugh score before and after each procedure in each group were statistically analyzed by means of Wilcoxon's signed rank test. One patient in Group 1 died of sepsis, acute respiratory distress syndrome, and persistent bleeding three days after TIPS, while the remaining 20 survived the procedure with immediate hemostasis. Hepatic encephalopathy developed in four patients (one in Group 1, three in Group 2, and none in Group 3); one, in Group 2, died while in an hepatic coma 19 months after TIPS. Rebleeding occurred in one patient, also in Group 2. Except for transient fever in two Group-3 patients, no procedure-related complication occurred. In terms of immediate hemostasis, rebleeding and encephalopathy, there were no statistically significant differences between the groups (p > 0.05). In Group 3, the Child-Pugh score showed a significant decrease after the procedure (p = 0.02). BRTO can effectively control active gastric variceal bleeding, and because of immediate hemostasis, the absence of rebleeding, and improved liver function, is a good alternative to TIPS in patients in whom such bleeding, accompanied by gastrorenal shunt, occurs.

    Full Text Available UNLABELLED: The aim of the present work was to test the potential of Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-ToF-MS in the diagnosis of liver cirrhosis and the assessment of disease severity by direct analysis of exhaled breath. Twenty-six volunteers have been enrolled in this study: 12 patients (M/F 8/4, mean age 70.5 years, min-max 42-80 years with liver cirrhosis of different etiologies and at different severity of disease and 14 healthy subjects (M/F 5/9, mean age 52.3 years, min-max 35-77 years. Real time breath analysis was performed on fasting subjects using a buffered end-tidal on-line sampler directly coupled to a PTR-ToF-MS. Twelve volatile organic compounds (VOCs resulted significantly differently in cirrhotic patients (CP compared to healthy controls (CTRL: four ketones (2-butanone, 2- or 3- pentanone, C8-ketone, C9-ketone, two terpenes (monoterpene, monoterpene related, four sulphur or nitrogen compounds (sulfoxide-compound, S-compound, NS-compound, N-compound and two alcohols (heptadienol, methanol. Seven VOCs (2-butanone, C8-ketone, a monoterpene, 2,4-heptadienol and three compounds containing N, S or NS resulted significantly differently in compensate cirrhotic patients (Child-Pugh A; CP-A and decompensated cirrhotic subjects (Child-Pugh B+C; CP-B+C. ROC (Receiver Operating Characteristic analysis was performed considering three contrast groups: CP vs CTRL, CP-A vs CTRL and CP-A vs CP-B+C. In these comparisons monoterpene and N-compound showed the best diagnostic performance. CONCLUSIONS: Breath analysis by PTR-ToF-MS was able to distinguish cirrhotic patients from healthy subjects and to discriminate those with well compensated liver disease from those at more advanced severity stage. A breath-print of liver cirrhosis was assessed for the first time.

    Full Text Available Background/Aims: Several studies have suggested that surgical resection (SR can provide a survival benefit over transarterial chemoembolization (TACE for hepatocellular carcinoma (HCC at the intermediate stage according to the Barcelona Clinic Liver Cancer (BCLC staging system. However, the criteria for SR remain to be determined. This study compared the long-term outcome of intermediate-stage HCC patients treated by either TACE or SR as a primary treatment modality, with the aim of identifying the patient subgroup that gained a survival benefit by either modality. Methods: In total, 277 BCLC intermediate-stage HCC patients treated by either TACE (N=225 or SR (N=52 were analyzed. Results: The overall median survival time was significantly better for SR than TACE (61 vs. 30 months, P=0.002. Decision-tree analysis divided patients into seven nodes based on tumor size and number, serum alpha-fetoprotein (AFP level, and Child-Pugh score, and these were then simplified into four subgroups (B1–B4 based on similarities in the overall hazard rate. SR provided a significant survival benefit in subgroup B2, characterized by ‘oligo’ (2–4 nodules of intermediate size (5–10 cm when the AFP levels was <400 ng/ml, or ‘oligo’ (2–4 nodules of small to intermediate size (<10 cm plus a Child-Pugh score of 5 when the AFP level was ≥400 ng/mL (median survival 73 vs. 28 months for SR vs. TACE respectively; P=0.014. The survival rate did not differ significantly between SR and TACE in the other subgroups (B1 and B3. Conclusion: SR provided a survival benefit over TACE in intermediate-stage HCC, especially for patients meeting certain criteria. Re-establishing the criteria for optimal treatment modalities in this stage of HCC is needed to improve survival rates.

    Full Text Available BACKGROUND: Acute variceal haemorrhage is a complication of cirrhosis that can be life threatening. It is a pharmacist’s duty to ensure therapeutic and pharmaceutical care which is not only safe and effective for the patient but also is cost-effective in order to attain improvement of the patient’s quality of life. Therefore, pharmacoeconomic evaluation especially cost-effectiveness analysis (CEA, which compares costs and consequences of drug therapy, is needed. This study was aimed to evaluate the therapeutic cost-effectiveness of hematemesis-melena treatment in hepatic cirrhotic patients. METHODS: A total of 42 patients receiving vitamin K and vitamin K-transamin were studied retrospectively from patients’ medical records in 2 years and analyzed with cost-effectiveness grid and average cost-effectiveness ratio (ACER based on Child-Turcotte-Pugh (CTP Score. RESULTS: Cost-effectiveness grid was dominant for vitamin K in patients with CTP Score A. ACER analysis showed a lower score for vitamin K in all patients included CTP Score classification. There was no significant difference in duration of cessation of bleeding treatment in patients with vitamin K compared with vitamin K-transamin in patients with CTP Score A and B, while significant difference was found in patients with CTP Score C. CONCLUSIONS: Vitamin K appeared to be more cost effective as compared with vitamin K-transamin in all patients. The use of vitamin K had greater benefit than the combination with transamin in all patients and CTP Score classification, and thus should be considered as a primary therapy. Therefore, transamin addition as an alternative therapy for hepatic cirrhosis patients with hematemesis-melena should be considered. KEYWORDS: CEA, cost-effectiveness analysis, child-turcotte-pugh score, hepatic cirrhosis, hematemesismelena, vitamin K, transamin.

    Background: Hepatocellular carcinoma (HCC) is a major health problem in Egypt as well as in many countries. Trans arterial chemo embolization (TACE) is a treatment modality applicable to locally advanced HCC beyond surgery or ablative therapies and is associated with survival improvements. The aim of this study was to assess the outcomes of TACE in our center over the past four years. Methods: This is a retrospective cohort study that included 221 patients with locally advanced HCC treated with TACE in a single center between the years 2007 and 2010. The median age was 57 years with male predominance. Liver cirrhosis, viral hepatitis and Bilharziasis were encountered in 64%, 31% and 8% of patients, respectively. Abdominal pain was the most common presenting symptom (67%). Most cases were diagnosed based on radiology (57%) with a TNM stage I or II (73%) and a median AFP value of 150 ng/m L. Results: 221 patients received 440 cycles of TACE with a median of 2 cycles per patient. Cisplatin and doxorubicin (50 mg per cycle, each) were the most commonly used drugs. Impaired liver function was the most common toxicity. Liver cell failure occurred in 17% of patients. An objective tumor response was achieved in 44% of cases. The median overall survival (OS) was 16 months (95% Cl, 13-19 months) and the median progression free survival (PFS) was 6 months (95% Cl, 4.3-7.8 months). Responding patients, Child-Pugh class A and patients receiving standard doses of chemotherapy had a significantly better OS than their counterparts. Only Child-Pugh class A was associated with significantly longer PFS (p < 0.001). Conclusion: TACE produces reasonable responses and fair survival rates in locally advanced HCC but with noticeable toxicities. Proper patients selection and prompt liver support are mandates for improving TACE outcomes.

    Pomalidomide is an immunomodulatory drug and the dosage of 4 mg per day taken orally on days 1-21 of repeated 28-day cycles has been approved in the European Union and United States to treat patients with relapsed/refractory multiple myeloma. Because pomalidomide is extensively metabolized prior to excretion, a total of 32 subjects (8 healthy subjects in group 1; 8 subjects with severe hepatic impairment in group 2; 8 subjects with moderate hepatic impairment in group 3; and 8 subjects with mild hepatic impairment in group 4) were enrolled in a multicenter, open-label, single-dose study to assess the impact of hepatic impairment on pomalidomide exposure. Following administration of a single oral dose of 4-mg pomalidomide, the geometric mean ratios of pomalidomide total plasma exposures (AUC) were 171.5%, 157.5%, and 151.2% and the geometric mean ratios of pomalidomide plasma peak exposures (C max ) were 75.8%, 94.8%, and 94.2% for subjects with severe, moderate, or mild hepatic impairment, respectively, versus healthy subjects. Pomalidomide administered as a single oral 4-mg dose was safe and well tolerated by healthy subjects and subjects with severe, moderate, or mild hepatic impairment. Based on the pharmacokinetic results from this study, the pomalidomide prescribing information approved by the US Food and Drug Administration recommends for patients with mild or moderate hepatic impairment (Child-Pugh classes A or B), a 3-mg starting daily dose (25% dose reduction) and for patients with severe hepatic impairment (Child-Pugh class C), a 2-mg starting daily dose (50% dose reduction). © 2018 The Authors.

    Full Text Available BACKGROUND: Algesia and inflammation are related with several pathological conditions. It is known that many drugs available for the treatment of these problems cause unwanted side effects. This study was aimed at evaluating acute toxicity and anti-inflammatory activity of Lampaya medicinalis Phil. (Verbenaceae widely used in the folk medicine of Northern Chile against rheumatism, arthritis and body joints pain. RESULTS: Oral administration of hydroalcoholic extract (HAE at the highest dose of 3000 mg/ Kg body weight resulted in no mortalities or evidence of significant behavioral changes. Histological examination revealed normal architecture and no significant adverse effects were observed on the liver, kidney, heart, lung or ovaries and testicles. The results suggest that the oral administration of hydroalcoholic extract (HAE from Lampaya medicinalis did not produce any toxic effect in rats. Hydroalcoholic extract (HAE significantly inhibited the carrageenan-induced rat paw edema in dose - response relationship, at test doses of 37.5, 75, 150 and 300 mg/Kg body weight. Maximum inhibition (61.98 ± 2.69% was noted at 300 mg/Kg after 2 h of drug treatment carrageenan induced paw edema, whereas indomethacin produced 47.90 ± 1.16% of inhibition. The inhibitory values of edema at 3 h postcarrageenan were 31.04±0.75%, 40.51 ± 2.36%, 48.97 ± 1.14% and 56.87 ± 0.41% for 37.5, 75, 150, and 300 mg/kg of extract respectively. Indomethacin (10 mg/Kg gave a percentage inhibition of 49.44 ± 1.44. HAE (300 and 150 mg/kg induced an anti-inflammatory effect greater than (or comparable with the effect of indomethacin from 2nd to 4th hours of the experiment. CONCLUSIONS: Our results reveal for first time that compounds contained in the hydroalcoholic extract ofLampaya medicinalis Phil exert anti-inflammatory effect and the oral administration is safe and non toxic up to dose level 3000 mg/kg body weight.

    First principles calculations are applied in the study of FeMP (M = Ti, Zr, Hf) compounds. We investigate the structural, elastic, mechanical and electronic properties by combining first-principles calculations with the CASTEP approach. For ideal polycrystalline FeMP (M = Ti, Zr, Hf) the shear modulus, Young's modulus, Poisson's ratio, elastic anisotropy indexes, Pugh's criterion, elastic wave velocities and Debye temperature are also calculated from the single crystal elastic constants. The shear anisotropic factors and anisotropy are obtained from the single crystal elastic constants. The Debye temperature is calculated from the average elastic wave velocity obtained from shear and bulk modulus as well as the integration of elastic wave velocities in different directions of the single crystal.

    The band structure calculations are performed on the intermetallic compounds Rh{sub 3}V and Rh{sub 3}V{sub x}(Al){sub 1-x} by Full Potential Linearized Augmented Plane Wave(FP-LAPW) method. Total energies are calculated as a function of volume and fitted to Birch-Murnaughan equation of state to find the lattice parameter and the other ground state properties. The ductility of these compounds has been analyzed using Cauchy’s Pressure, Pugh Rule and Poisson’s ratio. From this study we observed that Rh{sub 3}V is brittle while its alloy Rh{sub 3}V{sub 0.875}Al{sub 0.125} is ductile. Electron density plots are illustrated and compared.

    Achalasia is very uncommon, and rarely does achalasia co-exist with esophageal varices. We present a 62-year-old woman who was diagnosed with both achalasia and esophageal varices in December 2014 and had a past history of hematemesis. The patient's achalasia symptoms' Eckardt score was 9, and her hepatic function was Child-Pugh grade A6. After comprehensive assessment of the patient's health and discussion of the pros and cons of various therapies for achalasia, the patient underwent a peroral endoscopic myotomy. She was symptom-free after the operation and had no recurrence of achalasia symptoms at 20-month follow-up. No adverse events were reported. Peroral endoscopic myotomy for achalasia with esophageal varices has not been previously reported in the English literature.

    Full Text Available Young gay men’s negative perceptions of growing older have been indicated in prior research [Bergling, 2004; Jones & Pugh, 2005; Cohler & Galatzer-Levy, 2000]. A recent resurgence of HIV infection rates among young gay men [Mitsch et al, 2008] calls into question whether these negative perceptions contribute to a lack of future-oriented health investments; i.e., a “live for now” outlook. Strength of future orientation has repeatedly predicted risk aversion [McCabe & Barnett, 2000], hence, it is of great social and public health value to ask: what does aging mean to today’s youngest generation of gay men? How do cultural norms in the gay community inform how today’s young gay men imagine growing older? This research explores these questions.

    2006-01-01

    To study the effects of serum insulin-like growth factor-I (IGF-I) on bone metabolism in liver cirrhosis, 44 patients with hepatic cirrhosis were divided into 3 groups according to disease severity (Child Pugh Score) and 38 healthy subjects served as controls. Serum levels of IGF-I and osteocalcin(BGP) were measured in all patients and controls. Results showed that levels of IGF-I, BGP, and BMD were lower significantly in patients with liver cirrhosis than that in controls. When the condition of cirrhosis more deteriorated, these changes became much lower significantly. Serum levels of BGP and BMD were positively correlated with IGF-I. The decreasing level of IGF-I might be an important factor causing osteoporosis in patients with liver cirrhosis. (authors)

    Full Text Available HCC is diagnosed in approximately half a million people per year, worldwide. Staging is a more complex issue than in most other cancer entities and, mainly due to unique geographic characteristics of the disease, no universally accepted staging system exists to date. Focusing on survival rates we analyzed demographic, etiological, clinical, laboratory and tumor characteristics of HCC-patients in our institution and applied the common staging systems. Furthermore we aimed at identifying the most suitable of the current staging systems for predicting survival.Overall, 405 patients with HCC were identified from an electronic medical record database. The following seven staging systems were applied and ranked according to their ability to predict survival by using the Akaike information criterion (AIC and the concordance-index (c-index: BCLC, CLIP, GETCH, JIS, Okuda, TNM and Child-Pugh. Separately, every single variable of each staging system was tested for prognostic meaning in uni- and multivariate analysis. Alcoholic cirrhosis (44.4% was the leading etiological factor followed by viral hepatitis C (18.8%. Median survival was 18.1 months (95%-CI: 15.2-22.2. Ascites, bilirubin, alkaline phosphatase, AFP, number of tumor nodes and the BCLC tumor extension remained independent prognostic factors in multivariate analysis. Overall, all of the tested staging systems showed a reasonable discriminatory ability. CLIP (closely followed by JIS was the top-ranked score in terms of prognostic capability with the best values of the AIC and c-index (AIC 2286, c-index 0.71, surpassing other established staging systems like BCLC (AIC 2343, c-index 0.66. The unidimensional scores TNM (AIC 2342, c-index 0.64 and Child-Pugh (AIC 2369, c-index 0.63 performed in an inferior fashion.Compared with six other staging systems, the CLIP-score was identified as the most suitable staging system for predicting prognosis in a large German cohort of predominantly non-surgical HCC-patients.

    Full Text Available Background: In liver cirrhosis, the population of E coli is increased. conditions such as reduced intestinal. Escherichia coli with 2 enzyme nitrate reductase (NRF and Nir reduce nitrate to nitrite and subsequently converted to ammonia (99% and nitric oxide (1% in anaerobic condition. Regular aerobic exercise 2-3 times/week for 30 minutes resulted in increased 2,3-DPG which reduces the activity of E. coli to reduce nitrate to nitrite and ammonia, which only works on the anaerobic state. High Nitrate Diets lead to increased nitrate reducing bacteria such as E. coli resulting in the reduction of nitrate excess produce nitrite and ammonia in large quantities. Probiotic Lactobacillus spp. can suppress the growth of bacterial endotoxins and pathogens such as E. coli and other Enterobacteriaceae. This study aimed to determine the correlation of aerobic exercise and a high nitrate diet in gastrointestinal populations of Escherichia coli gastrointestinal tract in patient with liver cirrhosis. Method: This was a descriptive-experimental study in liver cirrhosis patients Child Pugh A/B in outpatient clinic Saiful Anwar Hospital in August 2015. Respondents were asked to fill out a questionnaire with information about the demographic data, the nitrate diet, aerobic exercise, other medical data and sanitation, and stool samples were taken for faecal culture. Eta Correlation statistical test was used to determine the correlation of aerobic exercise and a high nitrate diet high in population of E. coli. The significant difference are indicated by p < 0.005. Results: A total of 36 patients diagnosed with liver cirrhosis Child Pugh A/B, 14 (39% underwent aerobic exercise 3x /week, as many as 25 (70% consume a high nitrate diet. There was a strong relationship between aerobic exercise and high nitrate diet with population of E. coli (Ƞ = 0.725; p < 0.05. Conclusion: There was a strong relationship between aerobic exercise and high nitrate diet with a population

    The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis. Forty-eight patients with cirrhosis (21 women, 27 men; mean age, 67.8 years) with PSS underwent balloon-occluded retrograde transvenous obliteration (BRTO) at one institution between February 2008 and June 2014. The causes of cirrhosis were hepatitis B in one case, hepatitis C in 20 cases, alcohol in 15 cases, nonalcoholic steatohepatitis in eight cases, and other conditions in four cases. The Child-Pugh classes were A in 24 cases, B in 23 cases, and C in one case. The indication for BRTO was gastric varices in 40 cases and hepatic encephalopathy in eight cases. Testing was conducted before and 1 month after the procedure. Statistical analyses were performed to identify predictors of a clinically significant decline in ammonia levels after BRTO. Occlusion of PSS resulted in a clinically significant decrease in ammonia levels accompanied by increased portal venous flow and improved Child-Pugh score. Univariate analyses showed that a reduction in ammonia levels due to BRTO was significantly related to lower plasma glucose levels, higher RBC counts, and higher hemoglobin concentration before the treatment. Furthermore, multivariate logistic regression identified preoperative plasma glucose level as the strongest independent predictor of a significant ammonia reduction in response to BRTO. In addition, although BRTO resulted in significantly declined ammonia levels in patients with normal glucose tolerance before the procedure, ammonia levels were not significantly decreased after shunt occlusion in patients with diabetes mellitus or impaired glucose tolerance before BRTO, according to 75-g oral glucose tolerance test results. Preoperative plasma glucose level is a useful predictor of clinically significant ammonia reduction resulting from occlusion of PSS in patients with cirrhosis. Even if PSS are present, control

    Full Text Available ABSTRACT BACKGROUND: The Amazon region is one of the main endemic areas of hepatitis delta in the world and the only one related to the presence of genotype 3 of the delta virus. OBJECTIVE: To analyze the profile, mortality and survival of cirrhotic patients submitted to liver transplantation for chronic hepatitis delta virus and compare with those transplanted by hepatitis B virus monoinfection. METHODS: Retrospective, observational and descriptive study. From May 2002 to December 2011, 629 liver transplants were performed at the Walter Cantídio University Hospital, of which 29 patients were transplanted due to cirrhosis caused by chronic delta virus infection and 40 by hepatitis B chronic monoinfection. The variables analyzed were: age, sex, MELD score, Child-Pugh score, upper gastrointestinal bleeding and hepatocellular carcinoma occurrence before the transplantation, perioperative platelet count, mortality and survival. RESULTS: The Delta Group was younger and all came from the Brazilian Amazon Region. Group B presented a higher proportion of male patients (92.5% compared to Group D (58.6%. The occurrence of upper gastrointestinal bleeding before transplantation, MELD score, and Child-Pugh score did not show statistical differences between groups. The occurrence of hepatocellular carcinoma and mortality were higher in the hepatitis B Group. The survival in 4 years was 95% in the Delta Group and 75% in the B Group, with a statistically significant difference (P=0.034. Patients with hepatitis delta presented more evident thrombocytopenia in the pre-transplantation and in the immediate postoperative period. CONCLUSION: The hepatitis by delta virus patients who underwent liver transplantation were predominantly male, coming from the Brazilian Amazon region and with similar liver function to the hepatitis B virus patients. They had a lower incidence of hepatocellular carcinoma, more marked perioperative thrombocytopenia levels and frequent

    To investigate the clinical course of untreatable hepatocellular carcinoma (HCC) identified at any stage and to identify factors associated with mortality. From January 1999 to December 2010, 320 out of 825 consecutive patients with a diagnosis of HCC and not appropriate for curative or palliative treatments were followed and managed with supportive therapy. Cirrhosis was diagnosed by histological or clinical features and liver function was evaluated according to Child-Pugh score. The diagnosis of HCC was performed by Ultra-Sound guided biopsy or by multiphasic contrast-enhanced computed tomography or gadolinium-enhanced magnetic resonance imaging. Data were collected for each patient including all clinical, laboratory and imaging variables necessary for the outcome prediction staging systems considered. HCC staging was performed according Barcelona Clinic Liver Cancer (BCLC) and Cancer of the Liver Italian Program scores. Follow-up time was defined as the number of months from the diagnosis of HCC to death. Prognostic baseline variables were analyzed by multivariate Cox analysis to identify the independent predictors of survival. Seventy-five per cent of patients had hepatitis C. Ascites was present in 169 patients (53%), while hepatic encephalopathy was present in 49 patients (15%). The Child-Pugh score was class A in 105 patients (33%), class B in 142 patients (44%), and class C in 73 patients (23%). One hundred patients (31%) had macroscopic vascular invasion and/or extra-hepatic spread of the tumor. A single lesion > 10 cm was observed in 34 patients (11%), while multinodular HCC was present in 189 patients (59%). Thirty nine patients (12%) were BCLC early (A) stage, 55 (17%) were BCLC intermediate (B) stage, 124 (39%) were BCLC advanced (C) stage, and 102 (32%) were end-stage BCLC (D). At the time of this analysis (July 2011), 28 (9%) patients were still alive. Six (2%) patients who were lost during follow-up were censored at the last visit. The overall

    Using the density functional theory calculations, the mechanical and electronic properties of NbAl3 under different tensile loads were investigated. The calculated lattice parameters, elastic constants and mechanical properties (bulk modulus, shear modulus, Young's modulus, Poisson's ratio, Pugh's criterion and Cauchy's pressure) indicated that our results were in agreement with the published experimental and theoretical data at zero tension. With respect to NbAl3 under tension in this paper, the crystal structure was changed from tetragonal to orthorhombic under tension along the [100] and [101] directions. The NbAl3 crystal has been classified as brittle material under tension from 0 to 20 GPa. The obtained Young's modulus and Debye temperature monotonically decreased with increasing tension stress. Combining with mechanical and electronic properties in detail, the decreased mechanical properties were mainly due to the weakening of covalency.

    BACKGROUND AND AIMS: The impaired glucose tolerance in cirrhosis is poorly understood. We evaluated the influence of gastrointestinal-mediated glucose disposal and incretin effect in patients with cirrhosis. METHODS: Non-diabetic patients with Child Pugh A or B cirrhosis (n = 10) and matched...... of intravenous glucose in patients with cirrhosis compared to 24 ± 10 g in healthy controls (P = 0.003). The gastrointestinal-mediated glucose disposal was markedly lower in patients with cirrhosis (30 ± 23 vs. 52 ± 20%; P = 0.003). Despite higher levels of the incretin hormones glucagon-like peptide-1 (GLP-1......) and glucose-dependent insulinotropic peptide (GIP) patients with cirrhosis had reduced incretin effect (35 ± 44 vs. 55 ± 30%; P = 0.008). CONCLUSIONS: Impaired gastrointestinal-mediated glucose disposal and reduced incretin effect may contribute to the glucose intolerance seen in patients with cirrhosis....

    Objective: To evaluate the factors leading to hyperkalemia in patients with cirrhosis receiving spironolactone. Results: Patients with hyperkalemia (K>5 mmol/l) had higher blood urea nitrogen, serum creatinine and bilirubin levels (p=0.004, 0.001 and 0.044 respectively). Their serum sodium and albumin levels were lower (p=0.000 and 0.017 respectively). They had advanced cirrhosis with high Pugh score (p=0.003). These patients were on higher dose of spironolactone (p=0.001). Multivariate analysis showed that dose of spironolactone > 100 mg/day, serum creatinine >1.3 mg/dl, persistence of ascites and edema, and female gender were important predictors of development of hyperkalemia. Conclusion: Patients with cirrhosis receiving high dose of the diuretic, having edema, ascites and high serum creatinine are at the greater risk of developing hyperkalemia during spironolactone therapy.

    Full Text Available Liver failure has a high fatality rate and greatly threatens human health. Liver transplantation can effectively reduce the fatality rate. However, the problems such as donor shortage and allograft rejection limit the wide application of liver transplantation. An accurate early assessment helps to evaluate patients′ condition and optimize therapeutic strategies. At present, commonly used systems for prognostic evaluation include the King′s College Hospital, MELD, integrated MELD, Child-Pugh score, CLIF-SOFA, CLIF-C ACLFS, and D-MELD, and each system has its own advantages and disadvantages. Among these systems, the MELD scoring system is the most commonly used one, and the D-MELD scoring system is the most innovative one, which can be used for patients on the waiting list for liver transplantation. This article elaborates on the characteristics and predictive value of each scoring system in clinical practice.

  6. "Violence" in Sport and the Violenti non fit Iniuria Defence: A Perspective on the Death of the Cricket Player Phil Hughes

    Directory of Open Access Journals (Sweden)

    Pieter Labuschagne

    2018-03-01

    Full Text Available This article evaluates the defence of violenti non fit inuiria in sport with specific reference to the principle of bonos mores or the “good morals” in society to tolerate injuries in sport. The increased prevalence of serious injuries in sport in the professional era, in which sportsmen earn their livelihood from sport, necessitate a review of the existing situation. The death of the Australian cricket player, Phil Hughes, as a result of fast, short-pitched bowling in cricket, has again put the spotlight on the aggressive and excessive use of "violence" in sport. The malicious intent in sport, to harm or even to kill an opponent, has made it necessary to ask if there should be any difference in the manner in which the perpetrator of violence in sport should be treated as against ordinary criminal law assault and murder offenders. A two-pronged approach is suggested in the article as a possible way of dealing with wrongfulness in cricket.

    Full Text Available Dysbiosis of gut microbiota and metabolome is a frequently encountered condition in liver cirrhosis (LC patients. The severity of liver dysfunction was found to be correlated with the degree of microbial dysbiosis. Several clinical studies have indicated liver function improvement after therapeutic splenectomy for LC-induced hypersplenism. We sought to determine whether such post-splenectomy outcome is pertinent to modulation of the abnormal gut microenvironment in LC patients. A cross-sectional study including 12 LC patients and 16 healthy volunteers was first conducted, then a before–after study in the cohort of patients was carried out before and 6 months after splenectomy. Fecal samples were collected in hospital. Temporal bacterial (n = 40 and metabolomics (n = 30 profiling was performed using 16s rRNA gene sequencing and ultra performance liquid chromatography/mass spectrometer (UPLC/MS, respectively. Our results revealed that microbial composition in patients was clearly different from that in healthy controls (HCs, evidenced by considerable taxonomic variation. Along with improved liver function (Child–Pugh score, the patients also displayed similar gut microbiota profile and predicted metagenome function to that of HCs after splenectomy. Enterobacteriaceae and Streptococcaceae, two LC-enriched families showing positive relation with Child–Pugh score, exhibited significantly decreased abundance after splenectomy. At the genus level, 11 genera were differentially abundant between patients and HCs, but 9 genera of them restituted to normal levels by certain degree after splenectomy. PICRUSt analysis showed that the relative abundance of 17 KEGG pathways was partially restored after splenectomy. Four of them were amino acid-related pathways: lysine degradation, tryptophan degradation, amino acid metabolism, and protein digestion and absorption. These findings were supported by metabonomics results which showed that relative abundance

    Purpose: To evaluate quality of life (QoL), an important outcome owing to poor long-term survival, after stereotactic body radiation therapy (SBRT) to the liver. Methods and Materials: Patients (n=222) with hepatocellular carcinoma (HCC), liver metastases, or intrahepatic cholangiocarcinoma and Child-Pugh A liver function received 24-60 Gy of 6-fraction image-guided SBRT. Prospective QoL assessment was completed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and/or Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep, version 4) questionnaires at baseline and 1, 3, 6, and 12 months after treatment. Ten HCC patients with Child-Pugh B liver function were also treated. Results: The QLQ-C30 was available for 205 patients, and 196 completed the FACT-Hep. No difference in baseline QoL (P=.17) or overall survival (P=.088) was seen between the HCC, liver metastases, and intrahepatic cholangiocarcinoma patients. Appetite loss and fatigue measured by the QLQ-C30 clinically and statistically worsened by 1 month after treatment but recovered by 3 months. At 3 and 12 months after treatment, respectively, the FACT-Hep score had improved relative to baseline in 13%/19%, worsened in 36%/27%, and remained stable in 51%/54%. Using the QLQ-C30 Global Health score, QoL improved in 16%/23%, worsened in 34%/39%, and remained stable in 50%/38% at 3 and 12 months, respectively. Median survival was 17.0 months (95% confidence interval [CI] 12.3-19.8 months). Higher baseline scores on both FACT-Hep and QLQ-C30 Global Health were associated with improved survival. Hazard ratios for death, per 10-unit decrease in QoL, were 0.90 (95% CI 0.83-0.98; P=.001) and 0.88 (95% CI 0.82-0.95; P=.001), respectively. Tumor size was inversely correlated with survival. Conclusions: Liver SBRT temporarily worsens appetite and fatigue, but not overall QoL. Stereotactic body radiation therapy is well tolerated and warrants

    This study aimed at identifying prior therapy dosimetric parameters using 99m Tc-labeled macro-aggregates of albumin (MAA) that are associated with contralateral hepatic hypertrophy occurring after unilobar radioembolization of hepatocellular carcinoma (HCC) performed with 90 Y-loaded glass microspheres. The dosimetry data of 73 HCC patients were collected prior to the treatment with 90 Y-loaded microspheres for unilateral disease. The injected liver dose (ILD), the tumor dose (TD) and healthy injected liver dose (HILD) were calculated based on MAA quantification. Following treatment, the maximal hypertrophy (MHT) of an untreated lobe was calculated. Mean MHT was 35.4 ± 40.4%. When using continuous variables, the MHT was not correlated with any tested variable, i.e., injected activity, ILD, HILD or TD except with a percentage of future remnant liver (FRL) following the 90 Y-microspheres injection (r = -0.56). MHT ≥ 10% was significantly more frequent for patients with HILD ≥ 88 Gy, (52% of the cases), i.e., in 92.2% versus 65.7% for HILD < 88 Gy (p = 0.032). MHT ≥ 10% was also significantly more frequent for patients with a TD ≥ 205 Gy and a tumor volume (VT) ≥ 100 cm 3 in patients with initial FRL < 50%. MHT ≥10% was seen in 83.9% for patients with either an HILD ≥ 88 Gy or a TD ≥ 205 Gy for tumors larger than 100cm 3 (85% of the cases), versus only 54.5% (p = 0.0265) for patients with none of those parameters. MHT ≥10% was also associated with FRL and the Child-Pugh score. Using multivariate analysis, the Child-Pugh score (p < 0.0001), FRL (p = 0.0023) and HILD (p = 0.0029) were still significantly associated with MHT ≥10%. This study demonstrates for the first time that HILD is significantly associated with liver hypertrophy. There is also an impact of high tumor doses in large lesions in one subgroup of patients. Larger prospective studies evaluating the MAA dosimetric parameters have to be conducted to confirm these promising results

All patients received SBRT treatment at a dose of 45 Gy/3f. The liver function was compared before and after SBRT treatment by the analysis of adverse hepatic reactions and changes in CTP classification.Results: After SBRT treatment, eight patients presented with decreases in CTP classification and 13 patients presented with ≥ grade 2 hepatic adverse reactions. For patients presenting with ≥ grade 2 hepatic adverse reactions, the total liver volume of ≤1,162 mL and a normal liver volume (total liver volume – gross tumor volume [GTV] of ≤1,148 mL were found to be independent risk factors and statistically significant (P<0.05.Conclusion: The total liver volume and normal liver volume are associated with the occurrence of ≥ grade 2 hepatic adverse reactions after SBRT treatment on HCC patients. Therefore, if the fractionated scheme of 45 Gy/3f is applied in SBRT for HCC patients, a total liver volume >1,162 mL and a normal liver

    2013-11-01

    Design excellence (DEX) tools have been widely used for years in some industries for their potential to facilitate new product development. The medical sector, targeted by cost pressures, has therefore started adopting them. Numerous tools are available; however only appropriate deployment during the new product development stages can optimize the overall process. The primary study objectives were to describe generic tools and illustrate their implementation and management during the development of new orthopaedic implants, and compile a reference package. Secondary objectives were to present the DEX tool investment costs and savings, since the method can require significant resources for which companies must carefully plan. The publicly available DEX method "Define Measure Analyze Design Verify Validate" was adopted and implemented during the development of a new spinal implant. Several tools proved most successful at developing the correct product, addressing clinical needs, and increasing market penetration potential, while reducing design iterations and manufacturing validations. Cost analysis and Pugh Matrix coupled with multi generation planning enabled developing a strong rationale to activate the project, set the vision and goals. improved risk management and product map established a robust technical verification-validation program. Design of experiments and process quantification facilitated design for manufacturing of critical features, as early as the concept phase. Biomechanical testing with analysis of variance provided a validation model with a recognized statistical performance baseline. Within those tools, only certain ones required minimum resources (i.e., business case, multi generational plan, project value proposition, Pugh Matrix, critical To quality process validation techniques), while others required significant investments (i.e., voice of customer, product usage map, improved risk management, design of experiments, biomechanical testing

    Purpose: To evaluate quality of life (QoL), an important outcome owing to poor long-term survival, after stereotactic body radiation therapy (SBRT) to the liver. Methods and Materials: Patients (n=222) with hepatocellular carcinoma (HCC), liver metastases, or intrahepatic cholangiocarcinoma and Child-Pugh A liver function received 24-60 Gy of 6-fraction image-guided SBRT. Prospective QoL assessment was completed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and/or Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep, version 4) questionnaires at baseline and 1, 3, 6, and 12 months after treatment. Ten HCC patients with Child-Pugh B liver function were also treated. Results: The QLQ-C30 was available for 205 patients, and 196 completed the FACT-Hep. No difference in baseline QoL (P=.17) or overall survival (P=.088) was seen between the HCC, liver metastases, and intrahepatic cholangiocarcinoma patients. Appetite loss and fatigue measured by the QLQ-C30 clinically and statistically worsened by 1 month after treatment but recovered by 3 months. At 3 and 12 months after treatment, respectively, the FACT-Hep score had improved relative to baseline in 13%/19%, worsened in 36%/27%, and remained stable in 51%/54%. Using the QLQ-C30 Global Health score, QoL improved in 16%/23%, worsened in 34%/39%, and remained stable in 50%/38% at 3 and 12 months, respectively. Median survival was 17.0 months (95% confidence interval [CI] 12.3-19.8 months). Higher baseline scores on both FACT-Hep and QLQ-C30 Global Health were associated with improved survival. Hazard ratios for death, per 10-unit decrease in QoL, were 0.90 (95% CI 0.83-0.98; P=.001) and 0.88 (95% CI 0.82-0.95; P=.001), respectively. Tumor size was inversely correlated with survival. Conclusions: Liver SBRT temporarily worsens appetite and fatigue, but not overall QoL. Stereotactic body radiation therapy is well tolerated and warrants

    2014-01-01

    The article presents the results of analysis of the frequency of detection of cryoglobulinemic syndrome (CGS) and insulin resistance (IR) in patients with HCV-associated liver cirrhosis (LC) depending on its stage. There were also evaluated clinical and laboratory features of the disease. The study involved 72 patients with chronic hepatitis C who were divided into 3 main groups according to the presence of LC. The I group included 32 patients with chronic hepatitis C without LC. The II group consisted of 19 patients with compensated HCV-associated LC and III group included 21 patients with decompensated LC. It was shown that terminal stages of the LC (class B-C by Child-Pugh) are characterized by more frequent presence of IR and CGS with more severe clinical picture, which may be caused not only by the influence of the hepatitis C virus (HCV), but also by the progression of LC.

    BACKGROUND & AIMS: It remains unclear whether diabetes increases the risk for hepatic encephalopathy (HE) in cirrhotic patients. We examined this question using data from three randomized trials of satavaptan, a vasopressin receptor antagonist that does not affect HE risk, in cirrhotic patients...... with ascites. METHODS: The trials included 1198 patients, and we excluded those with HE before or at randomization and followed the remaining patients for the one year duration of the trials. They were examined for HE regularly, and we compared rates of first-time overt HE between diabetics and non-diabetic......Com comorbidity score. RESULTS: We included 862 patients of whom 193 (22%) had diabetes. In total, they experienced 115 first-time episodes of overt HE during the follow-up. Fewer diabetics than non-diabetic patients were in Child-Pugh class C at baseline (13% vs. 23%), yet they had higher cumulative risk...

    Objective: To investigate the association between the serum contents of IGF-I, IGF-II and liver dysfunction (as classified with Child-Pugh grades). Methods: Liver function test profiles as well as serum IGF-I, IGF-II contents ( with IRMA) were studied in 46 patients with liver cirrhosis and 32 controls. Results: According to the degree of liver dysfunction, these 46 patients with cirrhosis could be classified as: Child Grade A, n=17; Child B, n=20; and Child C, n=9. The serum IGF-I and IGF-II contents in the cirrhotic patients were significantly lower than those in the controls (P<0.001). The levels dropped along with the progression of child classification grades. Changes of IGF-II were more sensitive than those of IGF-I. Conclusion: Serum IGF-I and IGF-II contents were closely associated with degree of liver dysfunction and might be of prognostic significance. (authors)

We forecast the structural stability of Co2TaZ alloys on the basis of total energy calculations and mechanical stability criteria. The elastic constants, robust spin-polarized ferromagnetism and electron densities in these half-metallic alloys are also discussed. The observed structural aspects calculated to predict the stability and equilibrium lattice parameters agree well with the experimental results. The elastic parameters like elastic constants, bulk, Young’s and shear moduli, poison’s and Pugh ratios, melting temperatures, etc have been put together to establish their mechanical properties. The elaborated electronic band structures along with indirect band gaps and spin polarization favour the application of these materials in spintronics and memory device technology.

    Full Text Available We report a successful treatment result in a rare case of hepatitis C virus-related cirrhosis, who had sustained hydrothorax after blunt thoracoabdominal trauma. This was a female patient with liver cirrhosis, Child–Turcotte–Pugh class A, without ascites before injury. She sustained blunt thoracoabdominal trauma with a left clavicle fracture dislocation and right rib fractures. There was no hemopneumothorax at initial presentation. However, dyspnea and right pleural effusion developed gradually. We inserted a chest tube to relieve the patient's symptoms, and the daily drainage amount remained consistent. Hepatic hydrothorax was confirmed by the intraperitoneal injection of radioisotope 99mTc-sulfur colloid that demonstrated one-way transdiaphragmatic flow of fluid from the peritoneal cavity to pleural cavities. Finally, the hydrothorax was treated successfully by minocycline-induced pleural symphysis. To the best of our knowledge, this is the first case of hepatic hydrothorax developed after thoracoabdominal trauma.

    Full Text Available Hepatic encephalopathy (HE is a common long term complication of porto-systemic shunt. We report herein the case of a 59-year-old man with Child-Pugh A cirrhosis treated successfully 9 years earlier with distal splenorenal shunt for uncontrolled variceal bleeding. In the last year, he developed a severe and persistent hepatic encephalopathy secondary to the shunt, which was resistant to medical therapy. As liver transplantation was not available and obliteration of the shunt was hazardous, we performed subtotal colectomy in order to reduce ammonia production. This therapeutic option proved successful, as the grade of encephalopathy decreased and the patient improved. Our experience indicates that colonic exclusion should be considered as an option in the management of HE refractory to medical treatment in highly selected patients when liver transplantation is not available or even as a bridge given the long waiting time on lists.

    NIMROD is a new code that will be used for the analysis of existing fusion experiments, prediction of operational limits, and design of future devices. An approach called Integrated Product Development (IPD) is being used for the development of NIMROD. It is a dramatic departure from existing practice in the fusion program. Code development is being done by a self-directed, multi-disciplinary, multi-institutional team that consists of experts in plasma theory, experiment, computational physics, and computer science. Customer representatives (ITER, US experiments) are an integral part of the team. The team is using techniques such as Quality Function Deployment (QFD), Pugh Concept Selection, Rapid Prototyping, and Risk Management, during the design phase of NIMROD. Extensive use is made of communication and internet technology to support collaborative work. Our experience with using these team techniques for such a complex software development project will be reported.

    Nike's advertising slogans--"Bo Knows," "Just Do It," and "There Is No Finish Line"--have moved beyond advertising into popular expression. Its athletic footwear and clothing have become a piece of Americana. Its brand name is as well known around the world as IBM and Coke. Behind the slogans and the flashy TV commercials is the vision of its founder, chairman, and CEO, Phil Knight. Since forming the company in 1962, Knight has taken Nike from a small-time distributor of Japanese track shoes to the top of the athletic shoe and apparel market. But not without a stumble. Along the way, Knight discovered that technological innovation alone could not continue to drive growth. When sales stagnated in the mid-1980s, Knight and Nike learned several hard lessons on how to build brands and understand consumers, and they transformed their technology company into a marketing company whose product is its most important marketing tool. "Ultimately," says Knight, "we wanted Nike to be the world's best sports and fitness company. Once you say that, you have a focus. You don't end up making wing tips or sponsoring the next Rolling Stones world tour." To keep the company growing, Nike began splitting its brands into sub-brands. In tennis, Nike divided its shoes into Challenge Court--for younger, more active players--and Supreme Court--for older, more mature players. That approach brought the company to a broader range of consumers while preserving the customer base. And to create an emotional tie with the consumer, Nike started advertising on TV. "Sports is at the heart of American culture," Knight says. "You can't explain much in 60 seconds, but when you show Michael Jordan, you don't have to. It's that simple."

    Full Text Available CONTEXT: Presently the MELD score is used as the waiting list criterion for liver transplantation in Brazil. In this method more critical patients are considered priority to transplantation. OBJECTIVE: To compare the results of liver transplantation when the chronologic waiting list was the criterion for organ allocation (pre-MELD era with MELD score period (MELD era in one liver transplantation unit in Brazil. METHODS: The charts of the patients subjected to liver transplantation at the Hospital de Clínicas da Universidade Federal do Paraná, Curitiba, PR, Brazil, were reviewed from January of 2001 to August of 2008. Patients were divided into two groups: pre-MELD era and MELD era. They were compared in relation to demographics of donors and receptors, etiology of cirrhosis, cold and warm ischemia time, presence of hepatocellular carcinoma, MELD score and Child-Pugh score and classification at the time of transplantation, units of red blood cells transfused during the transplantation, intensive care unit stay, total hospital stay and 3 month and 1 year survival. RESULTS: Initially, 205 liver transplantations were analyzed. Ninety four were excluded and 111 were included: 71 on the pre-MELD era and 40 on the MELD era. The two groups were comparable in relation to donors and receptors age and sex, etiology of cirrhosis and cold and warm ischemia time. The receptors of the MELD era had more hepatocellular carcinoma than those of the pre-MELD era (37.5% vs 16.9%. Patients with hepatocellular carcinoma had less advanced cirrhosis on both eras. The MELD score was the same on both eras. Excluding the cases of hepatocellular carcinoma, MELD era score was higher than pre-MELD score (18.2 vs 15.8. There were an increased number of transplants on Child-Pugh A and C and a decreased number on Child-Pugh B receptors on MELD era. Both eras had the same need of red blood cells transfusion, intensive care unit stay and hospital stay. Also, 3 month and 1 year

    Full Text Available This study presents a systematic approach for the development of an efficient steel beam section for modular construction based on Six-Sigma. Although the Six-Sigma is frequently implemented in manufacturing and other service industries, it is a relatively new concept in the area of building design and construction. As a first step in this approach, market studies and surveys are conducted to obtain the opinions of potential customers. Then the opinions of customers are converted into quality characteristics for the steel beam using the quality function deployment methodology. A steel hollow flanged channel is chosen as the main modular beam shape, and the design concept is derived and developed by applying the Pugh matrix methodology. A pilot test was performed to validate the effectiveness of the developed beam section. The results indicated that the developed channel beam section showed excellent performance and retained high accuracy in fabrication, thus resulting in a significant reduction of steel consumption.

    Effects of Ni vacancy, Ni antisite in Al sublattice, Cr in Al sublattice, Pt in Ni sublattice on the second-order elastic constants (SOECs) and third-order elastic constants (TOECs) of the B2 NiAl have been investigated using the first-principles methods. Lattice constant and the SOECs of NiAl are in good agreement with the previous results. The brittle/ductile transition map based on Pugh ratio G/B and Cauchy pressure Pc shows that Ni antisite, Cr, Pt and pressure can improve the ductility of NiAl, respectively. Ni vacancy and lower pressure can enhance the Vickers hardness Hv of NiAl. The density of states (DOS) and the charge density difference are also used to analysis the effects of vacancy, Ni antisite, Cr and Pt on the mechanical properties of NiAl, and the results are in consistent with the transition map. © 2014 Elsevier Ltd.

    Intraosseous (IO) vascular access has been used since the Second World War and is warranted when there is an emergency and/or urgent need to replenish the vascular pool. Despite long-term and satisfactory results from delivering large quantities of intravenous fluid via the medullary space of bone, use of this space for a distant receptacle for cerebrospinal fluid (CSF) diversion has seldom been considered. The current paper reviews the literature regarding the bony medullary space as a receptacle for intravenous fluid and CSF. Previous authors have demonstrated the potential of the diploic space of the calvaria for CSF shunting. Pugh and colleagues tested the ability of the cranium to receive and absorb a small amount of tracer fluid. The literature suggests that intraosseous placement of ventricular diversionary shunts is an alternative to more traditional sites such as the pleural cavity and peritoneum. When these latter locations are not available or are contraindicated, placement in the medullary space of bone is another option available to the surgeon.

    The objective of the present study is to evaluate whether IL-6, TNF-α, IL-10 are associated with nutritional status in patients with cirrhosis secondary to biliary atresia and compare to healthy controls. The parameters used for nutritional assessment were the standard deviation scores of height-for-age and of triceps skinfold thickness-for-age. The severity of cirrhosis was evaluated using the Child-Pugh score and PELD/MELD. Serum cytokines were measured using Cytometric Bead Array flow cytometry. IL-6, TNF-α, and IL-10 were significantly higher in the cirrhosis group when compared with the control group (2.4 vs. 0.24 (patresia, IL-6 could be used as a possible supporting biomarker of deficient nutritional status and elevated IL-10 levels could be used as a possible early-stage supporting biomarker of deteriorating nutritional status.

    This study examined 19 patients with portosystemic shunt encephalopathy caused by a splenorenal shunt (SRS), which was treated with balloon-occluded retrograde transvenous obliteration (B-RTO). Long-term treatment outcomes were evaluated based on hepatic functional reserve and vital prognosis. Encephalopathy improved in all patients after shunt embolization and closure. Albumin, serum ammonia, and the Child-Pugh score, a measure of liver function, were significantly improved 3 years after B-RTO, and exacerbation of damage to liver function was avoided (pliver failure and two patients from hepatocellular carcinoma. Patients had a poor prognosis if their albumin levels were less than 2.8 mg / dL before B-RTO (pEncephalopathy patients had complete response to B-RTO, but long-term prognosis was affected by hepatic functional reserve before B-RTO and by concurrent hepatocellular carcinoma. The results of this study suggest that in patients with SRS, it is important to perform B-RTO at an early stage when the hepatic functional reserve is still satisfactory.

    Full Text Available Phycella australis (Phil. Ravenna is a Chilean plant with high ornamental potential; however, the intensive extraction as a cut flower might be detrimental for the conservational state by ignoring the state of genetic variation. The objective of this investigation was to assess genetic variability within and between three populations of P. australis in the Biobío Region using inter-simple sequence repeat (ISSR markers. The evaluated areas correspond to three locations in the province of Concepción, Biobío Region: Desembocadura (36°48' S, 73°10' W, Santa Juana (36°58' S, 72°58' W, and Lipinhue (37°00' S, 72°58' W. Six ISSR primers were used obtaining 51 fragments, from which 72.5% were polymorphic. From the three evaluated sites Santa Juana showed a higher percentage of polymorphic loci (76.47%. From this variability, 83% belong to within population variability and only 17% belong to variability between populations. The dendrogram generated using the unweighted pair group method with arithmetic mean (UPGMA method, grouped Lipinhue and Santa Juana sites together, which agrees with the geographic locations. This investigation proved that P. australis has high genetic variability despite the exploitation for economic purposes.

    Highlights: •Although a patient with a ruptured HCC is generally considered to have a poor prognosis and treated as T4 in the 7th edition of the AJCC/UICC, some ruptured cases show a good clinical course. •There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC) which is classified as T4 in TNM stage of UICC 7th. •This article describes that better prognosis can be expected with curative treatment in patients with a ruptured HCC, especially those with a single tumor, and without decompensated liver cirrhosis and PVTT/extrahepatic metastasis. T4 classification should not include all types of ruptured HCC. -- Abstract: Background: There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC). To elucidate the clinical features of affected patients, we examined prognosis and therapy choices. Materials/methods: We enrolled 67 patients treated for a ruptured HCC (HCV 44, HBV 5, HBV + HCV 1, alcohol 2, others 15; naïve HCC 34, recurrent 33) from 2000 to 2013, and investigated their clinical background and prognosis. Results: Median survival time (MST) for all cases was 4 months. For patients who survived for more than 1 year after rupture, the percentages of Child-Pugh C and positive for portal vein tumor thrombosis (PVTT)/extrahepatic metastasis were less than for those who died within 1 year. Child-Pugh classification (A:B:C = 14:15:5 vs. 4:9:20, P < 0.001) was better, while the percentage of patients with multiple tumors was lower [19/34 (55.9%) vs. 29/33 (87.9%), respectively; P < 0.001] in the naïve group. The 1- and 3-year survival rates were better in the naïve as compared to the recurrent group (60.6% and 33.3% vs. 12.6% and 0%, respectively; P < 0.01). MST according to modified TNM stage (UICC 7th) calculated after exclusion of T4 factor of rupture, stage I was better than others (22.7 vs. (II) 2.2, (III) 1.2, and (IV) 0.7 months) (P = 0.010). Conclusion: In patients with a ruptured

    Variceal bleeding is a serious complication in patients with cirrhosis. Among the criteria that were proposed in Baveno conferences, the Adjusted Blood Requirement Index (ABRI) has not been validated prospectively in clinical practice. We therefore aim to evaluate the measurement of ABRI as a marker of failure to control bleeding and to evaluate the consistency of ABRI in relation to other criteria of failure to control variceal bleeding. All patients with variceal bleeding who presented to Aga Khan University Hospital from January 2010 to December 2012 who were administered transfusion of packed red blood cells were included after obtaining informed consent. All patients were managed as per the standard protocol with intravenous terlipressin along with band ligation and injection of cyanoacrylate in cases of esophageal and fundal varices, respectively. Hemoglobin and hematocrit were measured every 6 h for 48 h and then every 12 h until 5 days of index bleed in each patient. Packed cells were transfused if hemoglobin decreased below 8 g/dl. The number of blood units transfused, change in hemoglobin values, and ABRI were calculated after each unit of blood transfusion till 120 h. In patients in whom bleed could not be controlled, an ABRI value of 0.75 or more was compared with other Baveno IV-based parameters that define failure to control variceal bleeding. During the study period, 137 eligible patients with variceal bleed were admitted. The mean age of the patients was 52±12 years. The majority of patients (50.4%) were in Child-Pugh class B, followed by 38% in Child-Pugh class C. According to the Baveno IV criteria, overall failure to control acute variceal bleeding occurred in 52 (37.9%) patients. Excluding ABRI, failure to control bleeding was found in 22/137 (16%) patients, whereas ABRI-based criteria showed that in 34/137 (24.8%) patients, bleeding could not be controlled. There were only four (2.9%) patients with variceal bleeding in whom ABRI and

    Full Text Available Introduction and objective: acquired chronic hepatocerebral degeneration, acquired hepatolenticular degeneration or pseudo-Wilson is an infrequent disorder with a hepatic origin. Cases in the literature are scarce and it is frequently confused with hepatic encephalopathy and Wilson's disease. The aim of this essay is to report a patient suffering from this disorder due to cirrhosis from non-alcoholic steatohepatitis. Case report: we present a 54-year-old man diagnosed from cirrhosis grade B9 of the Child Pugh classification. He progressively developed a picture with bradylalia, mild postural and action tremor and spatial and temporal disorientation. Further studies demonstrated an increase of the values of hepatic transaminases and a hiperintensity in the basal nuclei in the cerebral magnetic resonance imaging. Clinical and radiological data established the diagnosis of hepatocerebral degeneration. Conclusions: acquired chronic hepatocerebral degeneration is a disorder rarely reported in the literature that it is usually confused with other diseases. We alert about the need of having this diagnosis into account with patients developing neurological symptoms after hepatic disease.Fundamento y objetivo: el síndrome hepatocerebral crónico, también denominado degeneración hepatolenticular crónica adquirida (DHCA o pseudo-Wilson, es un trastorno poco frecuente de origen hepático.

    Our goal was to limit liver toxicity and to obtain good efficacy by developing a dosimetric treatment planning strategy. While several dosimetric evaluations are reported in literature, the main problem of the safety of the treatment is rarely addressed. Our work is the first proposal of a treatment planning method for glass spheres, including both liver toxicity and efficacy issues. Fifty-two patients (series 1) had been treated for intermediated/advanced hepatocellular carcinoma (HCC) with glass spheres, according to the Therasphere® prescription of 120 Gy averaged on the injected lobe. They were retrospectively evaluated with voxel dosimetry, adopting the local deposition hypothesis. Regions of interest on tumor and non tumor parenchyma were drawn to determine the parenchyma absorbed dose, averaged also on non irradiated voxels, excluding tumor voxels. The relationship between the mean non tumoral parenchyma absorbed dose D and observed liver decompensation was analyzed. Basal Child-Pugh strongly affected the toxicity incidence, which was 22% for A5, 57% for A6, 89% for B7 patients. Restricting the analysis to our numerically richest class (basal Child-Pugh A5 patients), D median values were significantly different between toxic (median 90 Gy) and non toxic treatments (median 58 Gy) at a Mann-Withney test, (P=0.033). Using D as a marker for toxicity, the separation of the two populations in terms of area under ROC curve was 0.75, with 95% C.I. of [0.55-0.95]. The experimental Normal Tissue Complication Probability (NTCP) curve as a function of D resulted in the following values: 0%, 14%, 40%, 67% for D interval of [0-35] Gy, [35-70] Gy, [70-105] Gy, [105-140] Gy. A limit of about 70 Gy for the mean absorbed dose to parenchyma was assumed for A5 patients, corresponding to a 14% risk of liver decompensation. This result is applicable only to our administration conditions: glass spheres after a decay interval of 3.75 days. Different safety limit (40 Gy) are

    Pugh, Philip

    2007-01-01

    The Sun provides amateur astronomers with one of the few opportunities for daytime astronomy. In order to see the major features of our nearest star, special telescopes that have a very narrow visible bandwidth are essential. The bandwidth has to be as narrow as 1 A- 10-10 m (1 Angstrom) and centred on the absorption line of neutral hydrogen. This makes many major features of the Suna (TM)s chromosphere visible to the observer. Such narrow-band "Fabry-Perot etalon filters" are high technology, and until the introduction of the Coronado range of solar telescopes, were too expensive for amateur use. The entry-level Coronado telescope, the PST (Personal Solar Telescope) costs under 500. Solar prominences (vast columns of plasma, best seen at the edge of the solar disk), filaments, flares, sunspots, plage and active regions are all visible and can be imaged to produce spectacular solar photographs. Philip Pugh has assembled a team of contributors who show just how much solar work can be done with Coronado telesco...

    To evaluate the serum levels of endozepine-4, their relation with ammonia serum levels, the grading of coma and the severity of cirrhosis, in patients with hepatic coma. In this study we included 20 subjects with Hepatic coma, 20 subjects with minimal hepatic encephalopathy (MHE) and 20 subjects control. All subjects underwent blood analysis, Child Pugh and Model for End - stage liver disease (MELD) assessment, endozepine-4 analysis. Subjects with hepatic coma showed significant difference in endozepine-4 (P blood ammonia concentration was noted to be raised in patients with hepatic coma, with the highest ammonia levels being found in those who were comatose. We also found a high correlation between endozepine-4 and ammonia (P < 0.001). In patients with grade IV hepatic coma, endozepine levels were significantly higher compared to other groups. This study suggests that an increased level of endozepine in subjects with higher levels of MELD was observed. In conclusion, data concerning involvement of the GABA-ergic system in HE coma could be explained by stage-specific alterations.

    Purpose: To evaluate the clinical effectiveness of self-expandable metallic stents in seven patients with malignant gastroduodenal obstruction caused by inoperable hepatocellular carcinoma (HCC). Methods: Seven patients with gastroduodenal obstruction caused by advanced HCC underwent metallic stent placement from 2003 to 2010. These patients had total dysphagia (n = 5) or were able to eat only liquids (n = 2) before stent placement. Patients had Eastern Cooperative Oncology Group performance scores of 2 or 3, and Child-Pugh classification B or C. Results: Stent placement was technically successful in all seven patients (100%) and clinically successful in six (86%). Five patients could eat a soft diet, and one patient tolerated regular diet after stent placement. Stent-related obstructive jaundice occurred in one patient. One patient had hematemesis 11 days after stent placement. Overall mean survival was 51 days (range, 10-119 days). Stent patency was preserved in six patients with clinical success until death. Conclusion: Placement of a covered self-expandable metallic stent may offer good palliation in patients with gastroduodenal obstruction due to advanced HCC.

    To determine the efficacy of L-ornithine-L-aspartate in treatment of hepatic encephalopathy. Cirrhotic patients with hyperammonemia and overt hepatic encephalopathy were enrolled. Eighty patients were randomized to two treatment groups, L-ornithine-L-aspartate (20g/d) or placebo, both dissolved in 250mL of 5% dextrose water and infused intravenously for four hours a day for five consecutive days with 0.5 g/kg dietary protein intake at the end of daily treatment period. Outcome variables were postprandial blood ammonia and mental state grade. Adverse reactions and mortality were also determined. Both treatment groups were comparable regarding age, gender, etiology of cirrhosis, Child-Pugh class, mental state grade and blood ammonia at baseline. Although, improvement occurred in both groups, there was a greater improvement in L-ornithine-L-aspartate group with regard to both variables. Four patients in the placebo group and 2 in L-ornithine-L-aspartate group died. L-ornithine-L-aspartate infusions were found to be effective in cirrhotic patients with hepatic encephalopathy.

    Full Text Available Abstract Background Although numerous chemotherapeutic agents have been tested, the role of systemic chemotherapy for hepatocellular carcinoma (HCC has not been clarified. New therapeutic strategies are thus needed to improve outcomes, and we designed this study with new effective drug combination. Methods Twenty-nine patients with histologically-confirmed, metastatic HCC received a combination chemotherapy with doxorubicin 60 mg/m2 and cisplatin 60 mg/m2 on day 1, plus capecitabine 2000 mg/m2/day as an intermittent regimen of 2 weeks of treatment followed by a 1-week rest. Results The median age was 49 years (range, 32–64 and 19 patients were hepatitis B virus seropositive. Child-Pugh class was A in all patients and 4 had Zubrod performance status of 2. The objective response rate was 24% (95% CI 9–40 with 6 stable diseases. The chemotherapy was generally well tolerated despite one treatment-related death. Conclusion Combination chemotherapy with doxorubicin, cisplatin and capecitabine produced modest antitumor activity with tolerable adverse effects in patients with metastatic HCC.

  6. Political Economy of Piracy in Somalia: Basis for a Transformative Approach

    2010-12-01

    Full Text Available This article examines the current wave of piracy off the coast of Somalia in light of political economy framework proposed by Michael Pugh and Neil Cooper. According to these authors, three types of economies flourish in protracted conflicts - combat economy, shadow economy, and coping economy - whose aims are, respectively, to finance combat activities, generate personal profits and provide minimum resources to the subsistence of poor and marginalized people. Based on empirical evidences showing that piracy in Somalia performs these three functions, one argues that the current international intervention against piracy is not sustainable because it does not seek to transform the factors and dynamics that make piracy an economically attractive alternative for local populations. For this reason, one proposes a shift on the Somali piracy agenda by adopting a critical perspective where piracy is no longer treated exclusively as a mere disruption of order at sea. Instead, one suggests a transformative approach where piracy is understood in its political economy dimension taking into account not only the local aspects, but also their regional links.

    Vitamin D (VD) is known to have multiple extra-skeletal health functions. There is emerging interest in exploring the relationship between vitamin D and chronic liver disease (CLD). To determine the prevalence of VD deficiency in patients with CLD in our setting and to assess whether VD supplementation influences plasma levels and is associated with improved liver function. We conducted a study in 2 phases. First, we analysed clinical and epidemiological characteristics in 94 patients with CLD; second, different doses of calcifediol (25-OH-VD) were administered to patients with VD deficiency (C (7.75ng/mL). After VD supplementation, optimal serum levels were achieved in 94% of patients and significant improvements were observed in platelet count, albumin levels (P<.05) and functional status assessed by the Child-Pugh scale (P<.05). Given the high prevalence of VD deficiency or insufficiency, the need for screening should be considered in the population with CLD. VD supplementation could be safe and effective.

    In this study, quaternary Heusler alloys CoFeCrZ (Z = Si, As, Sb) were investigated based on the modified Becke-Johnson exchange potential. The electronic structures demonstrated that CoFeCrZ (Z = Si, As, Sb) alloys are completely spin polarized with indirect bandgap and has an integer magnetic moment according to the Slater-Pauling rule. Pugh's and Poisson's ratios showed that these materials are highly ductile with high melting temperatures. The thermal properties comprising the thermal expansion coefficient, heat capacity, and Grüneisen parameter were evaluated at various pressures from 0 to 20 GPa. The Grüneisen parameter values indicated the strong anharmonicity of the lattice vibrations that predominated in these compounds. We also studied the dependency of the thermoelectric transport properties on the temperature, i.e., the thermal conductivity and Seebeck coefficient. These alloys exhibited low lattice thermal conductivity and good Seebeck coefficients at room temperature. The half-metallic structures of these compounds with large band gaps and adequate Seebeck coefficients mean that they are suitable for use in spintronic and thermoelectric device applications.

    To evaluate the cardiovascular and splanchnic hemodynamic changes in patients with liver cirrhosis and to compare with those of the normal controls using doppler ultrasonography. A total of 129 patients including 23 of Child-Pugh class A, 24 of class A, 24 of class B, 30 of class C, and 52 of the control group were included. Cardiac output (CO), systemic vascular resistance index (SVRI), and blood flow and pulsatility index (PI) of the superior mesenteric artery (SMA) were evaluated and compared among each groups. CO and SMA blood flow in the cirrhotic group were significantly higher than those in the control group, and the increase in CO and SMA blood flow showed a statistically significant correlation with the degree of liver dysfunction (p 2 =0.230). Hyperdynamic circulatory changes such as increases in CO and splanchnic blood flow were present in patients with liver cirrhosis. These changes may contribute to the development and maintenance of the portal hypertension due to an increase in portal blood flow an increase in portal blood flow.

This study aimed to determine the prevalence of malnutrition and to compare nutritional differences between various aetiologies. Methodology A cross-sectional study of adult patients with decompensated cirrhosis was conducted. Nutritional status was assessed using standard anthropometry, serum visceral proteins and subjective global assessment (SGA. Results Thirty six patients (mean age 59.8 ± 12.8 years; 66.7% males; 41.6% viral hepatitis; Child-Pugh C 55.6% with decompensated cirrhosis were recruited. Malnutrition was prevalent in 18 (50% patients and the mean caloric intake was low at 15.2 kcal/kg/day. SGA grade C, as compared to SGA grade B, demonstrated significantly lower anthropometric values in males (BMI 18.1 ± 1.6 vs 26.3 ± 3.5 kg/m2, p Conclusion Significant malnutrition in Malaysian patients with advanced cirrhosis is common. Alcoholic cirrhosis may have more malnutrition compared to other aetiologies of cirrhosis.

PATIENTS AND METHODS: A total of 300 consecutive patients attended at the outpatient clinics of a reference center for liver diseases were investigated. Anthropometric evaluation was performed by the usual parameters: triceps skinfold, arm circumference and arm muscle circumference. Biochemical parameters included creatinine/height index, serum albumin and lymphocytes count. The nutritional diagnosis was based on the PCM score proposed by Mendenhall et al. Food intake was retrospectively evaluated using 24-hour dietary recall data. RESULTS: About 71% of the patients studied were chronic alcohol abusers, whereas in 29% cirrhosis was of nonalcoholic etiology. Independently of the disease etiology 75.3% of the patients showed some degree of protein-calorie malnutrition, which was moderate or severe in 38.3% of them. More advanced protein-calorie malnutrition degrees were associated with lower energy and protein intake. The prevalence of moderate or severe protein-calorie malnutrition was higher in patients classified as Child-Pugh C than in patients classified as Child-Pugh A (21% x 58%, respectively. Regarding sexual differences, fat reserves, evaluated by triceps skinfold, were more depleted in females than in males (48.6% x 26.6% regardless of the etiology of the cirrhosis, whereas muscle reserves (arm muscle circumference were more depleted in males (43.4% x 13.4% regardless of the etiology of cirrhosis. In contrast, cirrhosis of alcoholic etiology was determinant in reducing arm muscle circumference in females (20% x 9.1% CONCLUSIONS: These data highlight the

    Selection of patients for hepatectomy for hepatocellular carcinoma conventionally has been based upon Child-Pugh grading. However, postoperative liver failure after hepatectomy is a major cause of hospital mortality. A new predictor of postoperative liver failure is required. The objective of this study was to identify risk factors for postoperative liver failure after hepatectomy. Perioperative risk factors for liver failure after hepatectomy were analyzed in 112 patients with hepatocellular carcinoma Eight of these patients died of liver failure. Stepwise multivariate logistic regression was performed to investigate significant independent factors among 17 variables, including the serum alkaline phosphatase ratio (ALPR) on the first day after hepatectomy. ALPR was calculated as the postoperative ALP level divided by the ALP level before surgery. Significant risk factors of postoperative liver failure were ALPR on postoperative day 1 (ALPR1), sex, operative blood loss, and operative procedure. As an indicator of liver failure, the diagnostic accuracy of the ALPR1 was 93.7% when the ALPR was less than 0.4 on the first postoperative day. The ALPR and the serum total bilirubin concentration after hepatectomy were uncorrelated. ALPR1 is a useful predictor of liver failure after hepatectomy.

    Chronic liver disease affects 855 people per million in the UK. Previous studies have reported that coffee appears protective against the development of abnormal liver enzymes, hepatic fibrosis and cirrhosis. The aim of this study, the first in a Scottish population, was to compare coffee consumption in patients with liver disease and that of control populations to determine correlations between coffee intake and the incidence of non-cancerous liver disease and with Child's-Pugh and model for end-stage liver disease (MELD) scores. Two hundred and eighty-six patients attending the liver outpatient department at the Royal Infirmary of Edinburgh completed a questionnaire regarding coffee consumption and lifestyle factors. Control questionnaires were also completed by 100 orthopaedic outpatients and 120 medical students. Patients with cirrhosis (n = 95) drank significantly less coffee than those without cirrhosis (p = coffee consumption. Coffee drinking is associated with a reduced prevalence of cirrhosis in patients with chronic liver disease. However, there was no significant difference in the amount of coffee drunk by liver patients and the control groups. It is possible that by changing the amount of coffee drunk, the development of cirrhosis in liver disease could be postponed.

  18. Branched-chain amino acids to tyrosine ratio value as a potential prognostic factor for hepatocellular carcinoma.

    The prognosis of hepatocellular carcinoma (HCC) depends on tumor extension as well as hepatic function. Hepatic functional reserve is recognized as a factor affecting survival in the treatment of HCC; the Child-Pugh classification system is the most extensively used method for assessing hepatic functional reserve in patients with chronic liver disease, using serum albumin level to achieve accurate assessment of the status of protein metabolism. However, insufficient attention has been given to the status of amino acid (AA) metabolism in chronic liver disease and HCC. Fischer's ratio is the molar ratio of branched-chain AAs (BCAAs: leucine, valine, isoleucine) to aromatic AAs (phenylalanine, tyrosine) and is important for assessing liver metabolism, hepatic functional reserve and the severity of liver dysfunction. Although this ratio is difficult to determine in clinical situations, BCAAs/tyrosine molar concentration ratio (BTR) has been proposed as a simpler substitute. BTR correlates with various liver function examinations, including markers of hepatic fibrosis, hepatic blood flow and hepatocyte function, and can thus be considered as reflecting the degree of hepatic impairment. This manuscript examines the literature to clarify whether BTR can serve as a prognostic factor for treatment of HCC.

    To assess the impact of chronic liver disease (CLD) on ICU-acquired pneumonia. This was a prospective, observational study of the characteristics, microbiology, and outcomes of 343 consecutive patients with ICU-acquired pneumonia clustered according to the presence of CLD. Sixty-seven (20%) patients had CLD (67% had liver cirrhosis, LC), MELD score 26 ± 9, 20% Child-Pugh class C). They presented higher severity scores than patients without CLD both on admission to the ICU (APACHE II, LC 19 ± 6 vs. other CLD 18 ± 6 vs. no CLD 16 ± 6; p CLD patients. LC patients had higher 28- and 90-day mortality (63 vs. 28%, p CLD patients. Presence of LC was independently associated with decreased 28- and 90-day survival (95% confidence interval [CI], 1.982-17.250; p = 0.001; 95% confidence interval [CI], 2.915-20.699, p = 0.001, respectively). In critically ill patients with ICU-acquired pneumonia, CLD is associated with a more severe clinical presentation and poor clinical outcomes. Moreover, LC is independently associated with 28- and 90-day mortality. The results of this study are important for future trials focused on mortality.

    This study aimed to evaluate the initial outcomes of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in terms of tumor response and safety. HCC patients who were not indicated for standard curative local modalities and who were treated with PBT at Samsung Medical Center from January 2016 to February 2017 were enrolled. Toxicity was scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was evaluated using modified Response Evaluation Criteria in Solid Tumors (mRECIST). A total of 101 HCC patients treated with PBT were included. Patients were treated with an equivalent dose of 62-92 GyE 10 . Liver function status was not significantly affected after PBT. Greater than 80% of patients had Child-Pugh class A and albumin-bilirubin (ALBI) grade 1 up to 3-months after PBT. Of 78 patients followed for three months after PBT, infield complete and partial responses were achieved in 54 (69.2%) and 14 (17.9%) patients, respectively. PBT treatment of HCC patients showed a favorable infield complete response rate of 69.2% with acceptable acute toxicity. An additional follow-up study of these patients will be conducted.

  1. Hölder properties of perturbed skew products and Fubini regained

    In 2006, Gorodetski proved that central fibres of perturbed skew products are Hölder continuous with respect to the base point. In this paper, we give an explicit estimate of this Hölder exponent. Moreover, we extend Gorodetski's result from the case when the fibre maps are close to the identity to a much wider class of maps that satisfy the so-called modified dominated splitting condition. In many cases (for example, in the case of skew products over the solenoid or over linear Anosov diffeomorphisms of the torus), the Hölder exponent is close to 1. This allows one to overcome the so-called Fubini nightmare, in some sense. Namely, we prove that the union of central fibres that are strongly atypical from the point of view of ergodic theory, has Lebesgue measure zero despite the lack of absolute continuity of the holonomy map for the central foliation. This result is based on a new kind of ergodic theorem, which we call special. To prove our main result, we revisit the theory of Hirsch, Pugh and Shub, and estimate the contraction constant of the graph transform map. (paper)

    The aim of this study was to evaluate the influence of Saccharomyces boulardii on the intestinal permeability, laboratory parameters and MELD and Child-Pugh severity scores in cirrhotic patients eligible for liver transplantation. Eighteen patients followed in a Transplant Outpatient Clinic were evaluated immediately before the beginning of treatment, after a 30-day period of treatment period with probiotics and at the end of the second study month (after a thirty-day period without probiotics). Fifteen healthy controls also underwent the intestinal permeability test (lactulose/mannitol). Before the probiotic, the median lactulose/ mannitol ratio was greater in the cirrhotic patients (0.0209, range 0.0012-0.1984) compared to the healthy controls (0.0030, range 0.0020-0.0013) (p boulardii, there was no improvement in intestinal permeability or significant differences in the laboratory parameters for the three evaluations. Patients eligible for liver transplants presented with increased intestinal permeability compared to healthy controls. A thirty-day treatment with S. boulardii did not improve this intestinal permeability or the severity scores, nor did it impact the laboratory parameters. Copyright AULA MEDICA EDICIONES 2014.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.

    Hepatocellular carcinoma (CHC) is one of the leading causes of worldwide cancer mortality. The aim of this study is to describe the clinical and epidemiological characteristics, as well as treatment prescribed in patients with this diagnosis. Longitudinal and prospective study that included patients with diagnosis of CHC in the Department of Digestive System at the HNERM-EsSalud between august 2007 and august 2008. We included 36 patients, median age was 60,1 years and 61,1% were male. Cirrhosis was present in 69,1% and median age in this group was 68,9 years, the median age in those without cirrhosis was 40 years (pChild-Pugh score B or C. Symptomatic treatment was prescribed in 44,4% of the patients. Epidemiological features are different between patients with or without cirrhosis. In the first case their characteristics are similar to those described in areas of low risk for CHC; in the second group the characteristics are similar to those described in areas with high risk population. CHC has frequent association with hepatitis B virus. High percentage of patients is diagnosed with an advanced stage of HCC.

Place and Duration of Study: Radiology Department, The Aga Khan University Hospital, Stadium Road, Karachi, from December 1997 to September 2005. Patients and Methods: Patients undergoing TACE procedure for HCC were prospectively followed. Forty three patients were enrolled from December 1997 to March 2003 in the study and subjected to chemo embolization therapy. Eight out of 43 patients were excluded from the study, who lost to follow-up. All the patients were followed till their death. Median and mean survival were calculated. Results: The median survival of these 35 patients was 410 days (13.6 months), with 95% confidence interval (236 days lower bound and 536 days upper bound). Mean survival time was 603 days (20.1 months) with 95% confidence interval (394 days lower bound and 812 days upper bound). There was significant difference in mean survival time (in days) by Child's Pugh class (X2 = 12.384; df=2, p-value=0.002). Conclusion: The study showed that TACE is an effective palliative treatment. TACE increases the median survival time. (author)

    Full Text Available Power hardware-in-the-loop (PHIL systems are advanced, real-time platforms for combined software and hardware testing. Two paramount issues in PHIL simulations are the closed-loop stability and simulation accuracy. This paper presents a virtual impedance (VI method for PHIL simulations that improves the simulation’s stability and accuracy. Through the establishment of an impedance model for a PHIL simulation circuit, which is composed of a voltage-source converter and a simple network, the stability and accuracy of the PHIL system are analyzed. Then, the proposed VI method is implemented in a digital real-time simulator and used to correct the combined impedance in the impedance model, achieving higher stability and accuracy of the results. The validity of the VI method is verified through the PHIL simulation of two typical PHIL examples.

    Full Text Available BACKGROUND: Infections after liver transplantations are the most important cause of morbi-mortality. In this study, we assessed the main characteristics of these infections in a southern Brazilian university hospital. METHODS: We conducted a retrospective cohort with 55 patients who underwent orthotopic liver transplantation between 1996 and 2000 in the "Hospital de Clínicas de Porto Alegre", Porto Alegre, RS, Brazil, to characterize the infections that occurred in the group. RESULTS: One or more infections (average 2.10 were diagnosed in 47 patients, especially during the first month after transplantation. The most common were bacteremia, intra-abdominal infections and pneumonia, predominantly with bacteria, especially Staphylococcus sp (and particularly S. aureus and E. coli. The mortality rate attributed to infections was high: 17 cases of all deaths (total 27 deaths. Significant risk factors for infections included reoperation, diabetes, biliary stenosis and higher Child-Pugh scores. CONCLUSION: Infections remain a severe threat in liver transplant patients, and special efforts should be made to prevent and manage them correctly.RACIONAL: Infecções são a causa principal de morbimortalidade em pacientes submetidos a transplantes hepáticos.

    Asymmetric somatic hybrids between Solanum tuberosum L. and S. brevidens Phil. have been obtained via the fusion of protoplasts from potato leaves and from cell suspension culture of S. brevidens. The wild Solanum species served as donor after irradiation of its protoplasts with a lethal X-ray dose (200 Gy). Selection of the putative hybrids was based on the kanamycin-resistance marker gene previously introduced into the genome of Solanum brevidens by Agrobacterium-mediated gene transfer. Thirteen out of the 45 selected clones exhibited reduced morphogenic potential. The morphological abnormalities of the regenerated plantlets were gradually eliminated during the extended in vitro culture period. Cytological investigations revealed that the number of chromosomes in the cultured S. brevidens cells used as protoplast source ranged between 28-40 instead of the basic 2n=24 value. There was a high degree of aneuploidy in all of the investigated hybrid clones, and at least 12 extra chromosomes were observed in addition to the potato chromosomes (2n=48). Interand intraclonal variation and segregation during vegetative propagation indicated the genetic instability of the hybrids, which can be ascribed to the pre-existing and X-ray irradiation-induced chromosomal abnormalities in the donor S. brevidens cells. The detection of centromeric chromosome fragments and long, poly-constrictional chromosomes in cytological preparations as well as non-parental bands in Southern hybridizations with restriction fragment length polymorphism (RFLP) markers revealed extensive chromosome rearrangements in most of the regenerated clones. On the basis of the limited number of RFLP probes used, preferential loss of S. brevidens specific markers with a non-random elimination pattern could be detected in hybrid regenerants

    Full Text Available Copao (Eulychnia acida Phil. is an endemic arborescent cactus restricted mainly to the semi-arid Coquimbo Region (29°54'28" S, 71°15'15" W, Chile. The area of distribution is from sea level to 1200 m.a.s.l. The edible fruit called rumpa is generally round, with green or pink peel and small scales on its surface, showing wide variability in size and weight. The aim of this work was to characterize the rumpa harvested in January 2009 and 2010 in three sectors of Coquimbo Region to determine chemical and nutritional composition in three fractions: pulp with seeds, juice, and peel. The research showed that this fruit is a good natural source of mainly soluble dietary fiber, which has a jellied texture and is present in the three fractions analyzed: 2% for juice, 3% for pulp with seeds, and approximately 5% for peel, making it potentially a good source of hydrocolloids for the food industry. The fruit is also a good source of vitamin C; around 55 mg 100 g-1 in peel, and 30 mg 100 g-1 in pulp with seeds and juice, values considered high compared to 18 mg 100 g-1 for prickly pear (Opuntiaficus-indica [L.] Mill. The main minerals were: K, Mg, Ca, and P. Total polyphenols and betalain pigments were also determined in the pulp with seeds and pink peel fractions, respectively. The nutritional characteristics, together with its high water content of around 96%, make rumpa a promising raw material for agro-industrial development of natural juices or isotonic drinks. This characterization helps in the recovery of an endemic native species by reducing potential threats to destroy wild populations of E. acid, especially near agricultural areas, and by promoting habitat conservation of the species in the region.El copao (Eulychnia acida Phil. es un cactus arborescente endémico restringido principalmente a la región semi árida de Coquimbo (29°54'28" S, 71°15'15" O, Chile.

    Power hardware-in-the-loop (PHIL) simulation, where actual hardware under text is coupled with a real-time digital model in closed loop, is a powerful tool for analyzing new methods of control for emerging distributed power systems. However, without careful design and compensation of the interface between the simulated and actual systems, PHIL simulations may exhibit instability and modeling inaccuracies. This paper addresses issues that arise in the PHIL simulation of a hardware battery inverter interfaced with a simulated distribution feeder. Both the stability and accuracy issues are modeled and characterized, and a methodology for design of PHIL interface compensation to ensure stability and accuracy is presented. The stability and accuracy of the resulting compensated PHIL simulation is then shown by experiment.

    The portal hypertension of hepatic cirrhosis was studied by 99m Tc-MIBI trans-rectum imaging. The portal systemic circulation was evaluated by the heart-liver ratio (H/L ratio) and the portosystemic shunt index (SI). The H/L and SI in 12 normal cases were 0.145 +- 0.042 and 0.124 +- 0.029. Whereas in 18 patients with hepatobiliary diseases of non-cirrhosis were 0.207 +- 0.076 and 0.169 +- 0.051, and in 47 patients with hepatic cirrhosis were 0.751 +-0.313 and 0.422 +- 0.075. The results showed significant difference (P<0.01) between normal controls and non-cirrhosis group, and significant difference (P<0.001) between hepatic cirrhosis group and normal controls, non-cirrhosis group. A significant difference (P<0.05) in child-pugh's classification A, B and C groups was also found. A significant correlation (r = 0.95, P<0.01) with the H/L, SI and portal pressure measurement during operation was found. If H/L≥0.30, and SI≥0.22 were taken as positive criteria for diagnosis of portal hypertension with hepatic cirrhosis, the sensitivity, specificity and accuracy were 96%, 90% and 94% respectively. Therefore, it was a new method for the diagnosis of portal hypertension with hepatic cirrhosis

    Full Text Available Preoperative serum lactate dehydrogenase (LDH has been used as a prognostic indicator for patients with hepatocellular carcinoma (HCC treated with sorafenib or undergoing transcatheter arterial chemoembolization, but its significance in predicting survival of HCC patients who received curative resection remains undefined. A total of 683 patients with histopathologically confirmed HCC were enrolled in this study. The prognostic significance of preoperative serum LDH was determined by Kaplan-Meier analysis and a Cox proportional hazards regression model. The association between the preoperative serum LDH and clinicopathological parameters was evaluated by the χ2 test or linear regression analysis when appropriate. Higher preoperative serum LDH level was associated with worse prognosis. In a multivariate Cox proportional hazards analysis, the preoperative serum LDH level could predict overall survival and recurrence independently. Higher preoperative serum LDH level is associated with the elevated serum alpha-fetoprotein, the presence of hepatitis B surface antigen, larger tumor size, the presence of macrovascular invasion, the advanced tumor–lymph node–metastasis stage, worse tumor differentiation, and Child-Pugh B. Preoperative serum LDH level was an inexpensive, simple, convenient, and routinely measured biomarker exhibiting a potential to select patients at high risk with poor clinical outcome for appropriate treatment strategies.

    Objective: To discuss the correlative factors affecting the short-term prognosis in treating malignant obstructive jaundice with percutaneous transhepatic biliary drainage (PTBD) and/or percutaneous transhepatic biliary stenting (PTBS). Methods: During the period of December 2008-June 2009, PTBD and/or PTBS were performed in 67 patients. The clinical date were reviewed and analyzed. According to the reduction degree of serum bilirubin and survival condition in 30 days, the patients were divided into effective group (54 cases) and ineffective group (13 cases). Single factor affecting the short-term prognosis was analyzed by using χ 2 test and multi-factors were analyzed by using non-conditional logistic regression mode. Results: Single variable analysis showed that time of obstruction, way of drainage, preoperative biliary infection, Child-Pugh grade, TBIL, HGB and Cr level were of statistical significance. The logistic regression analysis showed that there were obvious correlation among preoperative biliary infection, Child-grade ≥11 and Cr >115 μmol/L. Conclusion: The infection of the bile duct before operation, Child-grade ≥11 and Cr >115μmol/L carry a close relationship with the short-term prognosis of PTBD and PTBS. Therefore, an overall preoperative evaluation for malignant obstructive jaundice is of great importance. (authors)

    Advanced hepatocellular carcinoma (HCC) is associated with various clinical conditions including major vessel invasion, metastasis, and poor performance status. The aim of this study was to establish a prognostic scoring system and to propose a sub-classification of the Barcelona-Clinic Liver Cancer (BCLC) stage C. This retrospective study included consecutive patientswho received sorafenib for BCLC stage C HCC at a single tertiary hospital in Korea. A Cox proportional hazard model was used to develop a scoring system, and internal validationwas performed by a 5-fold cross-validation. The performance of the model in predicting risk was assessed by the area under the curve and the Hosmer-Lemeshow test. A total of 612 BCLC stage C HCC patients were sub- classified into strata depending on their performance status. Five independent prognostic factors (Child-Pugh score, α-fetoprotein, tumor type, extrahepatic metastasis, and portal vein invasion) were identified and used in the prognostic scoring system. This scoring system showed good discrimination (area under the receiver operating characteristic curve, 0.734 to 0.818) and calibration functions (both p advanced HCC. A prognostic scoring system with five independent factors is useful in predicting the survival of patients with BCLC stage C HCC.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    Determining the association of age and laboratory parameters with tumor size of hepatocellular carcinoma (HCC). The study was at Adam Malik Hospital Medan from June- December 2016. 100 HCC patients were enrolled; those with excluding liver metastatic. Baseline characteristics of gender, age, obtaining etiology of HCC. Liver function tests, viral marker, and INR were done. Based on tumor size from abdomen CT, patients were three groups: tumor size below 3 cm, 3-5 cm, and above 5 cm size. Patients were also divided based on Child-Pugh class. Correlation of age and laboratory results with tumor size of HCC patients were analyzed. Age have negative correlation with tumor size in HCC patients (r=-0.297, p=0.032) while AFP have positive correlation with tumor size (r0.446, p=<0.001). Total bilirubin, AST, and ALT have negative correlation but non-significant (r=-0.045, -0.078, - 0.126 respectively). Albumin and INR have positive correlation but non-significant (r=0.021, 0.112 respectively). Our study suggests that older age correlates with smaller tumor size, while AFP level has a significant correlation with tumor size in HCC patients. AFP level may be a useful marker for determining the prognosis of HCC patients.

    To determine whether or not cerebral myo-inositol/creatine-phos-phocreatine (MI/Cr) level can be used as a criterion of hepatic encephalopathy (HE). Single voxel stimulated echo sequence with short echo time (30ms) was applied to parietal white matter of 14 healthy control subjects, 11 patients with chronic viral hepatitis, 29 cirrhotic patients without HE, and 33 cirrhotic patients with HE. The metabolite ratios of N-acetylaspartate (NAA), choline containing compounds (Cho), and myo-Inositol (MI) were calculated using creatine/phosphocreatine (Cr) as an internal reference. Clinical data including modified Child-Pugh score, estimated serum osmolarity, and grade of HE, were obtained at the day of MR spectroscopy. MI/Cr was 34% lower in cirrhotic patients with HE than in control subjects. It was reduced below two standard deviation from normal in 17 of 33 cirrhotic patients with HE (52%). MI/Cr did not correlate with grade of HE (r=-0.55, p=0.00). In the analysis of Child class C patients, there was no significant difference of MI/Cr between cirrhotic patients with HE and those without HE (0.83 {+-} 0.11, n= 29 vs. 0.39 {+-} 0.11, n= 15, p= 0.59, respectively). A reduction of cerebral MI/Cr cannot be used as a diagnostic criterion of HE.

    To evaluate albumin-bilirubin (ALBI) and platelet-albumin-bilirubin (PALBI) grades in predicting overall survival in high-risk patients undergoing conventional transarterial chemoembolization for hepatocellular carcinoma (HCC). This single-center retrospective study included 180 high-risk patients (142 men, 59 y ± 9) between April 2007 and January 2015. Patients were considered high-risk based on laboratory abnormalities before the procedure (bilirubin > 2.0 mg/dL, albumin 1.2 mg/dL); presence of ascites, encephalopathy, portal vein thrombus, or transjugular intrahepatic portosystemic shunt; or Model for End-Stage Liver Disease score > 15. Serum albumin, bilirubin, and platelet values were used to determine ALBI and PALBI grades. Overall survival was stratified by ALBI and PALBI grades with substratification by Child-Pugh class (CPC) and Barcelona Liver Clinic Cancer (BCLC) stage using Kaplan-Meier analysis. C-index was used to determine discriminatory ability and survival prediction accuracy. Median survival for 79 ALBI grade 2 patients and 101 ALBI grade 3 patients was 20.3 and 10.7 months, respectively (P  .05). ALBI and PALBI grades are accurate survival metrics in high-risk patients undergoing conventional transarterial chemoembolization for HCC. Use of these scores allows for more refined survival stratification within CPC and BCLC stage. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

    Post-hepatectomy bile leak may lead to undesired morbidity. Multiple methods have been employed to identify this leak but can be inconclusive and taxing. This novel white gauze test is a simple and reliable method. This is a prospective study performed from January 2010 until March 2011. All open hepatic resection were included. Dry white gauze is compressed onto the transected surface and observed for bile staining. The leaking duct is repaired immediately upon detection. The process is repeated until negative. Drain was removed on postoperative day-5. Post-operative bile leak is defined as: 1. Bilirubin concentration of the drain fluid is 3 times or higher than serum; 2. Presence of intra-abdominal bile collection on imaging and upon drainage; 3. Bile leak demonstrated on postoperative cholangiography. 42 patients were recruited. Seven (16.7%) patients were cirrhotic with Child-Pugh A. White gauze test were positive for intra-operative bile leaks in 29 patients (70%), which were primarily repaired. As a result, there was no postoperative bile leak in this series. One mortality was detected in this series due to postoperative pancreatic fistula and multi organ failure. The White Gauze Test is a useful method for the prevention of bile leakage after hepatic resection. It is safe, quick and cheap.

    A phase II trial of pasireotide was performed to assess its efficacy and safety in advanced or metastatic hepatocellular carcinoma (HCC). Patients with advanced HCC and Child-Pugh score ≤7 received pasireotide LAR 60 mg intramuscularly every 28 days. Primary endpoint was disease control rate. Secondary endpoints were time to tumor progression, response rate, treatment-related adverse events, and overall survival. Serum insulin growth factor-1 was measured before and after pasireotide. Twenty patients were treated and evaluable. Eighteen patients (90%) had prior therapy; 16 patients (80%) had multiple therapies. Median age was 65, 75% had Barcelona Clinic Liver Cancer stage C, and 55% had metastatic disease. The main toxicity was hyperglycemia. Rare adverse effects included reversible grade 4 elevation in alanina transaminase/aspartate transaminase in one patient. The best response was stable disease in 9 patients (45%). Median time to tumor progression for the 20 patients was 3 months, and median survival was 9 months. Pasireotide had limited clinical benefit as second-line or third-line treatment in patients with advanced or metastatic HCC. Low baseline insulin growth factor-1 level may be indicative when SOM230 treatment may be ineffective, and decreasing levels after treatment may be indicative of disease control.

    Full Text Available Higher than normal plasma glutamine concentration at admission to an intensive care unit is associated with an unfavorable outcome. Very high plasma glutamine levels are sometimes seen in both acute and chronic liver failure. We aimed to systematically explore the relation between different types of liver failure and plasma glutamine concentrations.Four different groups of patients were studies; chronic liver failure (n = 40, acute on chronic liver failure (n = 20, acute fulminant liver failure (n = 20, and post-hepatectomy liver failure (n = 20. Child-Pugh and Model for End-stage Liver Disease (MELD scores were assessed as indices of liver function. All groups except the chronic liver failure group were followed longitudinally during hospitalisation. Outcomes were recorded up to 48 months after study inclusion.All groups had individuals with very high plasma glutamine concentrations. In the total group of patients (n = 100, severity of liver failure correlated significantly with plasma glutamine concentration, but the correlation was not strong.Liver failure, regardless of severity and course of illness, may be associated with a high plasma glutamine concentration. Further studies are needed to understand whether high glutamine levels should be regarded as a biomarker or as a contributor to symptomatology in liver failure.

    To present safety and efficacy results obtained in treatment of a cohort of patients with unresectable hepatocellular carcinoma (HCC) with use of 90Y microspheres (TheraSphere). Forty-three consecutive patients with HCC were treated with 90Y microspheres over a 4-year period. Patients were treated by liver segment or lobe on one or more occasions based on tumor distribution, liver function, and vascular flow dynamics. Patients were followed for adverse events, objective tumor response, and survival. Patients were stratified into three risk groups according to method of treatment and risk stratification (group 0, segmental; group 1, lobar low-risk; group 2, lobar high-risk) and Okuda and Child-Pugh scoring systems. Based on follow-up data from 43 treated patients, 20 patients (47%) had an objective tumor response based on percent reduction in tumor size and 34 patients (79%) had a tumor response when percent reduction and/or tumor necrosis were used as a composite measure of tumor response. There was no statistical difference among the three risk groups with respect to tumor response. Survival times from date of diagnosis were different among the risk groups (P TheraSpheres) provides a safe and effective method of treatment for a broad spectrum of patients presenting with unresectable HCC. Further investigation is warranted.

    Full Text Available Spondylodiscitis is an infection of the intervertebral disc space, involves the vertebrae, causing vertebral osteomyelitis and spread to adjacent epidural space, causing dural, radicular or spinal cord compression. Appears mainly in adult and immunocompromised patients, mainly by haematogenous inoculation from systemic infections with bacteriemia. Patients with hepatic cirrhosis have frequent bacteriemias, produced by increased gut permeability, immune dysfunction and frequent need for invasive procedures. Despite high frequency of blood stream infections, discitis and vestebral osteomyelitis are rarely reported. We present the case of a 53 years old woman, diagnosed with class B Child Pugh cirrhosis, which presents with intense back pain and cauda equina syndrome, without clinical signs of infection. Diagnosis was confirmed by spinal MRI, but very soon after treatment onset, the patient suffered a septic shock with haemodynamic instability, which leads to patient’s death. This case illustrates how an unusual complication of cirrhosis – bacteriemia - could precipitate the unfavorable evolution of the patient by producing a remote septic complication. Persistent back pain in a cirrhotic patient should also raise the hypothesis of an infectious cause, in which early management is essential. Early diagnosis in essential for successful treatment, and good prognosis after long-term antibiotic treatment can be achieved in the majority of patients.

    Sorafenib has been approved in the indication of unresectable hepatocellular carcinoma, but there are many cases in which administration of the drug is discontinued due to severe side effects. In this study, we compared the characteristics of patients who continued and discontinued sorafenib. Ninety-six patients (75 men and 21 women) were initiated on sorafenib from July 2009 through September 2011. The patient characteristics of interest included gender, age, etiology, Child-Pugh classification, treatment history and frequency, and levels of α-fetoprotein, des- gamma-carboxy prothrombin, aspartate amino acid transferase, and alanine aminotransferase. Duration of administration of sorafenib and reasons for its discontinuation were compared. Median overall survival was 11.8 months. Discontinuation of sorafenib within 90 days was identified as an independent prognostic factor for overall survival on multivariate analysis (P < 0.0001). Transarterial chemoembolization performed six times or more (P = 0.013) was also identified as an independent factor contributing to discontinuation of sorafenib within 90 days in multivariate analysis. Patients who received sorafenib for ≥90 days had significantly longer overall survival than those who discontinued it (P < 0.0001). Prolonged treatment with sorafenib is an important factor in achieving extended overall survival. We recommend starting sorafenib before latent liver damage has occurred as a result of too many transarterial chemoembolization procedures

    The application of mutation techniques, i.e. gamma rays and other physical and chemical mutagens has generated a vast amount of genetic variability and has played a significant role in plant breeding and genetics. The widespread use of mutation techniques in plant breeding programs throughout the world has led to the official release of more than 3000 mutant varieties from different plant species. These varieties provide higher yields, better quality, resistance to diseases and resilience to climate change and variability. In the Philippine Rice Research Institute (PhilRice), classical induced mutagenesis and/or in combination with modern technologies as an important tool in rice breeding have been widely utilized by breeders. These recent advances offered new and exciting challenges for the development of new varieties. Moreover, it has the advantage of free regulatory restrictions imposed on genetically modified organisms. To date, high generation of new varieties, elite lines and pre-breeding materials have been derived from chemical and physical mutagenesis, another culture, in vitro mutagenesis, and molecular marker technologies. Directly benefitting the farmers are three Philippine released varieties: PSB Rc78 developed through gamma ray induction in year 2000; and NSIC Rc272 (2011) and Rc346 (2013) developed by combination of Co60 induction and another culture technology. These varieties are intended for the lowlands. In the current works, diverse mutant lines and pre-breeding materials of different target traits were generated and are now under evaluation as potential varieties and/or for use in the inbred and hybrid breeding programs. These genetic materials are in the background of traditional and modern rice varieties. Accordingly, for inbreds, mutated traits ranged from changes in morphological traits, yield, maturity, grain quality, nutritional traits, abiotic resistance such as heat, salinity, and drought tolerance, biotic resistance such as bacterial

    Full Text Available The Agricultural Resources Extraction from LiDAR Surveys (PARMAP project component of the Nationwide Detailed Resources Assessment using LiDAR (Phil-LiDAR 2 Program aims to produce detailed agricultural maps using LiDAR. Agricultural land cover at crop level was classified through object based image analysis using Support Vector Machine as classifier and LiDAR derivatives from point cloud (2 points per sq.m. and orthophoto (0.5-meter resolution as inputs. An accuracy of at least 90 %, assessed using validation points from the field and through image interpretation, was required before proceeding to post-processing and map lay-out. Knowledge sharing and capacity development facilitated by the University of the Philippines Diliman (UPD enabled partner universities across the Philippines to produce outputs for their assigned region. Considering output layers were generated by multiple teams working on different landscape complexities with some degree of data quality variability, quality checking is crucial to ensure accuracy standards were met. UPD PARMap devised a centralized and end-to-end scheme divided into four steps – land classification, GIS post-processing, schema application, and map lay-out. At each step, a block is reviewed and, subsequently, either approved or returned with documentation on required revisions. Turnaround time of review is at least one block (area ranging from 10 to 580 sq. km. per day. For coastal municipalities, an additional integration process to incorporate mapped coastal features was applied. Common problems observed during quality checking include misclassifications, gaps between features, incomplete attributes and missing map elements. Some issues are particular to specific blocks such as problematic LiDAR derivatives. UPD addressed these problems through discussion and mentoring visits to partner universities. As of March 2017, a total of 336 municipal agricultural maps have been turned-over to various

    Power-hardware-in-the-loop (PHIL) is a simulation tool that can support electrical systems engineers in the development and experimental validation of novel, advanced control schemes that ensure the robustness and resiliency of electrical grids that have high penetrations of low-inertia variable renewable resources. With PHIL, the impact of the device under test on a generation or distribution system can be analyzed using a real-time simulator (RTS). PHIL allows for the interconnection of the RTS with a 7 megavolt ampere (MVA) power amplifier to test multi-megawatt renewable assets available at the National Wind Technology Center (NWTC). This paper addresses issues related to the development of a PHIL interface that allows testing hardware devices at actual scale. In particular, the novel PHIL interface algorithm and high-speed digital interface, which minimize the critical loop delay, are discussed.

    Vitamin A deficiency (VAD) and altered thyroid function are commonly encountered in patients with liver cirrhosis. The link between vitamin A metabolism and thyroid function has been previously identified. The aim of this study was to explore the association between VAD and the thyroid axis in clinically stable patients with cirrhosis related to hepatitis C virus (HCV). One hundred and twelve patients with clinically stable HCV-related cirrhosis and 56 healthy controls matched for age, sex, and socioeconomic status were recruited for this study. Vitamin A status, liver function, thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), reverse triiodothyronine (rT3), anti-thyroid peroxidase antibodies (anti-TPO), and thyroid volume were evaluated. The prevalence of VAD among patients with HCV-related cirrhosis was 62.5% compared with 5.4% among controls (P vitamin A status: VAD and normal vitamin A. Patients with VAD had significantly lower vitamin A intake and serum albumin and higher serum bilirubin, FT4, FT3, and TSH than patients with normal vitamin A status. Multiple logistic regression analysis revealed that VAD was associated with Child-Pugh score (β = 0.11, P = 0.05) and TSH (β = -1.63, P = 0.02) independently of confounding variables. We conclude that VAD may be linked to central hyperthyroidism in patients with clinically stable HCV-related liver cirrhosis.

    To assess the protein binding and pharmacokinetics of sacubitril/valsartan analytes (sacubitril, sacubitrilat, and valsartan) in an open-label, single oral dose (200 mg), parallel-group study in patients with mild and moderate hepatic impairment (Child-Pugh class A and B) and matched healthy subjects. This study enrolled 32 subjects (n = 8 in each hepatic impairment and matched healthy subjects groups). Blood samples were collected at pre-determined time points to assess pharmacokinetics of sacubitril, sacubitrilat, and valsartan. Subjects with severe hepatic impairment were excluded as valsartan exposure is expected to be substantially increased in these patients. Sacubitril exposure (AUC) increased by 53% and 245% while the exposure to sacubitrilat was increased by 48% and 90% in patients with mild and moderate hepatic impairment, respectively. Sacubitril Cmax increased by 57% and 210% in mild and moderate hepatic impairment; however, for both sacubitrilat and valsartan, Cmax was unchanged. Valsartan AUC increased in patients with mild and moderate hepatic impairment by 19 - 109%, respectively. The increase in systemic exposures to all sacubitril/valsartan analytes correlated with the severity of liver disease. The plasma unbound fraction of sacubitrilat in patients with moderate hepatic impairment was slightly higher than in matched healthy subjects. This difference was not considered clinically significant. Safety assessments showed that sacubitril/valsartan was safe and well tolerated across all the study groups.

    Transarterial chemoembolization (TACE) is established as bridging therapy of HCC listed for transplantation (LT). CT-guided brachytherapy (CTB) has not been evaluated as a bridging concept. We compared CTB and TACE for bridging before LT in HCC patients. Twelve patients with HCC received LT after CTB (minimal tumour dose, 15-20 Gy). Patients were matched (CTB:TACE, 1:2) by sex, age, number and size of lesions, and underlying liver disease with patients who received TACE before transplantation. Study endpoints were extent of necrosis at histopathology and recurrence rate after OLT. There were no significant differences between the CTB and TACE groups regarding Child-Pugh category (p = 0.732), AFP (0.765), time on waiting list (p = 0.659), number (p = 0.698) and size (p = 0.853) of HCC lesions, fulfilment of Milan-criteria (p = 0.638), or previous liver-specific treatments. CTB achieved higher tumour necrosis rates than TACE (p = 0.018). The 1- and 3-year recurrence rate in the CTB group was 10 and 10 % vs. TACE, 14 and 30 % (p = 0.292). Our data show comparable or even better response and post-LT recurrence rates of CTB compared to TACE for treating HCC in patients prior to LT. CTB should be further evaluated as an alternative bridging modality, especially for patients not suited for TACE. (orig.)

    Full Text Available Variceal bleeding and hepatorenal syndrome (HRS are serious and life-threatening complications of advanced liver disease. Terlipressin is widely used to manage both acute variceal bleeding and HRS due to its potency and long duration of action. The most severe (though rare adverse event is ischemia. The present report describes the case of a patient with gangrene and osteomyelitis secondary to terlipressin therapy. A 71-year-old male with alcoholic liver cirrhosis (Child-Pugh B and chronic hepatitis C was admitted due to a drowsy mental status. The patient had several experiences of orthopedic surgery. His creatinine level had gradually elevated to 4.02 mg/dL, and his urine output decreased to 500 mL/24 hr. The patient was diagnosed as having grade III hepatic encephalopathy (HE and type II HRS. Terlipressin and albumin were administered intravenously to treat the HRS over 11 days. Although he recovered from the HE and HRS, the patient developed peripheral gangrene and osteomyelitis in both feet. His right toes were cured with the aid of rescue therapy, but his left three toes had to be amputated. Peripheral gangrene and osteomyelitis secondary to terlipressin therapy occur only rarely, and there is no specific rescue therapy for these conditions. Thus, attention should be paid to the possibility of ischemia of the skin and bone during or after terlipressin therapy.

  15. Decreased prothrombin conversion and reduced thrombin inactivation explain rebalanced thrombin generation in liver cirrhosis.

    Directory of Open Access Journals (Sweden)

    Romy M W Kremers

    Full Text Available Impaired coagulation factor synthesis in cirrhosis causes a reduction of most pro- and anticoagulant factors. Cirrhosis patients show no clear bleeding or thrombotic phenotype, although they are at risk for both types of hemostatic event. Thrombin generation (TG is a global coagulation test and its outcome depends on underlying pro- and anticoagulant processes (prothrombin conversion and thrombin inactivation. We quantified the prothrombin conversion and thrombin inactivation during TG in 30 healthy subjects and 52 Child-Pugh (CP- A, 15 CP-B and 6 CP-C cirrhosis patients to test the hypothesis that coagulation is rebalanced in liver cirrhosis patients. Both prothrombin conversion and thrombin inactivation are reduced in cirrhosis patients. The effect on pro- and anticoagulant processes partially cancel each other out and as a result TG is comparable at 5 pM tissue factor between healthy subjects and patients. This supports the hypothesis of rebalanced hemostasis, as TG in cirrhosis patients remains within the normal range, despite large changes in prothrombin conversion and thrombin inactivation. Nevertheless, in silico analysis shows that normalization of either prothrombin conversion or thrombin inactivation to physiological levels, by for example the administration of prothrombin complex concentrates would cause an elevation of TG, whereas the normalization of both simultaneously maintains a balanced TG. Therefore, cirrhosis patients might require adapted hemostatic treatment.

    The design of drag cancellation missions of the future will take advantage of the technology experience of the past. The importance of data for modeling of the atmosphere led to at least six types of measurement: (a) balloon flights, (b) missile-launched falling spheres, (c) the 'cannonball' satellites of Ken Champion with accelerometers for low-altitude drag measurement (late 1960s and early 1970s), (d) the Agena flight of LOGACS (1967), a Bell MESA accelerometer mounted on a rotating platform to spectrally shift low-frequency errors in the accelerometer, (e) a series of French low-level accelerometers (e.g. CACTUS, 1975), and (f) correction of differential accelerations for drag errors in measuring gravity gradient on a pair of satellites (GRACE, 2002). The independent invention of the drag-free satellite concept by Pugh and Lange (1964) to cancel external disturbance added implementation opportunities. Its first flight application was for ephemeris prediction improvement with the DISCOS flight (1972)-still the only extended free test mass flight. Then successful flights for reduced disturbance environment for science measurement with gyros on GP-B (2004) and for improved accuracy in geodesy and ocean studies (GOCE, 2009) each using accelerometer measurements to control the drag-canceling thrust. LISA, DECIGO, BBO and other gravity wave-measuring satellite systems will push the cancellation of drag to new levels.

A total of 53 patients who had undergone sorafenib therapy were analyzed as the control group. The primary endpoint of this study was OS. Results The median number of MET cycles was two (1-15. The OS values for the MET group and sorafenib group were 158 days (132-184 and 117 days (92-142, respectively (P=0.029. The Cox proportional-hazard model showed that a higher risk of death was correlated with higher serum alpha fetoprotein level (≥400 mg/dL, hazard ratio [HR]=1.680, P=0.014 and Child-Pugh class B (HR=1.856, P=0.008. Conclusions MET was associated with more favorable outcomes in terms of overall survival than was sorafenib in patients with advanced HCC with PVTT, especially in patients with poor liver function. Therefore, MET can be considered as a treatment option in patients with advanced HCC with PVTT and poor liver function.

    BACKGROUND Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) are rational targets for therapy in hepatocellular cancer (HCC). METHODS Patients with histologically proven HCC and not amenable to curative or liver directed therapy were included in this 2-stage phase 2 trial. Eligibility included an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 and Child’s Pugh score of A or B, and 1 prior systemic therapy. Patients received erlotinib 150 mg daily and bevacizumab 10 mg/kg on days 1 and 15 every 28 days. Objective tumor response was the primary end point. RESULTS Twenty-seven patients with advanced HCC (median age, 60 years) were enrolled in this multi-institutional study. The proportion of patients with Child’s A classification was 74%. One patient had a confirmed partial response and 11 (48%) achieved stable disease. Median time to disease progression was 3.0 months (95% confidence interval [CI], 1.8-7.1). Median survival time was 9.5 months (95% CI, 7.1-17.1). Grade 3 toxicities included rash, hypertension, fatigue, and diarrhea. CONCLUSIONS In this trial, erlotinib combined with bevacizumab had minimal activity in patients with advanced HCC based on objective response and progression-free survival. The role of targeting EGFR and VEGF in HCC needs further evaluation in molecularly selected patients. PMID:21953248

    We wanted to evaluate the safety and efficacy of a new hemostatic device, Clo-Sur P.A.D., at an arterial access site after performing femoral arterial catheterization to achieve transcatheter arterial chemoembolization (TACE). From August 2002 to March 2005, 113 patients who underwent TACE and agreed on using the Clo-Sur P.A.D. were enrolled in this study. We evaluated the mean time interval from compression to the first movement and also to the first walk. We also evaluated such complications as rebleeding, pseudoaneurysm, vascular occlusion, hematoma, infection and pain. For 92 patients who had previous experiences with manual compression, we evaluated their preference of hemostatic method by asking them. Successful hemostasis was achieved with the Clo-Sur P.A.D. in 105 subjects (92%). The mean time interval from compression to the first movement was 201 minutes, and that to the first walk was 267 minutes. There was no statistical difference between the complicated and the uncomplicated groups for the mean time, prothrombin time, Child-Pugh class and platelet count (ρ > 0.05). Rebleeding occurred in 3 patients (2.7%) and mild hematoma around puncture site was noted in 5 patients (5.4%). Eighty-seven patients (95%) preferred Clo-Sur P.A.D. to the manual compression method. The Clo-Sur P.A.D. is a safe and effective hemostatic device and it provides early ambulation after TACE

    To evaluate the frequency, clinical associations and prognostic impact of hyponatraemia on cirrhosis related complications in patients with cirrhosis of liver. In this case control study 217 cirrhotic patients consecutively admitted to our department from September 2006 to November 2007 were studied. Serum sodium levels were determined in all patients admitted. The cutoff level of 130 meq/l was chosen because it is widely accepted to define hyponatraemia in patients with cirrhosis while the level of 135 meq/L is the lower normal value. Patients were grouped on the basis of serum sodium concentration into serum sodium 135 meq /l (Group 3). P values of less than 0.05 were considered as significant. The patients with hyponatraemia Group( 135 meq/l) for the severity of liver disease, degree of ascites and other cirrhosis related complications such as hepatorenal syndrome, spontaneous bacterial peritonitis and hepatic encephalopathy. This case control study constituted 217 consecutive cirrhotic patients of which 141(65%) were male and 76/217 (35%) were female. Hyponatraemia (sodium 135. Out of 58 patients with hyponatraemia, 48 were in child - Pugh C class (p=0.001). Patients with serum sodium 135 meq/l). Hyponatraemia is frequent in cirrhotic patients. It is seldom spontaneous and has a negative influence on cirrhosis related complications (JPMA 60:116; 2010). (author)

    Chronic liver disease secondary to hepatitis C virus (HCV) infection is a common clinical problem. HCV is likely to adversely affect the quality of life (QoL) of the patient. This effect is said to be disproportionate to the severity of the disease. The aim of our study was to evaluate QoL in HCV-positive patients focusing both on health status and subjective satisfaction. Twenty-four patients with combined HCV and alcoholic liver disease (ETOH-HCV) were enrolled in the study. We adopted two generic tools: SF-36 (a health status questionnaire) and SAT-P (a satisfaction profile) for psychological assessment of the patients. SF-36 and SAT-P scores of ETOH-HCV patients were compared with scores of 23 patients with alcoholic liver disease (ETOH). The scores obtained from the study groups were also compared with the reference scores of the healthy Italian population. Both the groups were comparable with respect to age, histological and clinical severity of liver disease (as assessed by MELD and Child Pugh scores). Patients with ETOH-HCV scored less in the vitality and role emotional status domains of the SF-36 scores and the psychological function, social function and free time domains of the satisfaction profile. These results show a significant impact of HCV infection on health status and subjective satisfaction. Copyright © 2011 S. Karger AG, Basel.

    Objective: To determine the causes, characteristics and predictors of mortality in patients with acute-on-chronic liver failure (ACLF). Study Design: Cross-sectional study. Place and Duration of Study:Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, from July 2014 to June 2016. Methodology:All patients with acute-on-chronic liver disease (ACLD) with ages > 12 were included. Patients with ACLF, as defined by the Asian Pacific Association for the Study of Liver (APASL, 2014) were identified. Predictors of mortality were identified using chi-square or Fisher's exact test. Results: Included in the study were 72 patients with mean age of 36.71 years, 46 (63.9%) being males. Among them, 61 developed ACLF. Commonest causes of chronic liver disease (CLD) were chronic viral hepatitis (37, 51.4%) and autoimmune hepatitis (14, 19.4%). Commonest causes of acute liver injury (ALI) were acute viral hepatitis (24, 33.3%) and drug induced liver injury (DILI) (17, 23.6%). Among those with ACLF, 24 (39.3%) patients died with median survival of 17.1 +-13.5 days. Mortality was significantly associated with Child Turcotte Pugh (CTP) score =>13 (p=0.010), model for end-stage liver disease (MELD) score =>30 (p=0.001), age >40 years (p=0.036), organ failures (OF) =>3 (p 3, CTP =>13, MELD =>30, age >40 years, PSE, renal failure and urosepsis.

    Full Text Available At present, liver transplantation remains the only curative option for the patients with cirrhosis and end-stage liver diseases. The survival rate and recurrent diseases remain the major issues in the patient post-transplantation. Unani medicine is one of the oldest traditional systems of medicine which has been treating chronic liver diseases and cirrhosis (Talayyaful-Kabid for centuries. The current study aimed to assess the impact of Unani treatment on decompensated cirrhosis and collect data to warrant further clinical trials. Authors conducted a case series on five patients with decompensated cirrhosis and portal hypertension. The disease was confirmed through FibroScan and ultrasound and treated with Unani treatment orally for seven months. Results were evaluated based on FibroScan, liver function test (LFT, EuroQol-5D (EQ5D, Child-Pugh and TTO-TIME (trade-off question. Significant improvements in LFT, fibrosis and quality of life were achieved in the studied patients. The literature related to the herbal constituents of chief medicines used to treat in this case was reviewed. The herbs proved their potential anti-oxidative, anti-inflammatory, hepato-protective, immuno-modulator and antiviral activities, suggesting plausible mechanisms of action in the cases. The preliminary findings indicated the potential therapeutic role of Unani treatment in decompensated cirrhosis. Clinical trials should be conducted to explore further therapeutic potential of Unani treatment in decompensated cirrhosis.

    Full Text Available Angiogenesis is believed to be implicated in the pathogenesis of alcoholic liver disease (ALD. We aimed to explore the usefulness and accuracy of plasma angiogenic biomarkers for noninvasive evaluation of the severity of liver failure and ALD outcome. One hundred and forty-seven patients with ALD were prospectively enrolled and assessed based on their (1 gender, (2 age, (3 severity of liver dysfunction according to the Child-Turcotte-Pugh and MELD scores, and (4 the presence of ALD complications. Plasma levels of vascular endothelial growth factor (VEGF-A and angiopoietins 1 and 2 (Ang1 and Ang2 were investigated using ELISAs. Multivariable logistic regression was applied in order to select independent predictors of advanced liver dysfunction and the disease complications. Significantly higher concentrations of Ang2 and VEGF-A in ALD patients as compared to controls were found. There was no difference in Ang1 levels in both groups. A positive correlation of Ang2 levels with INR (Rho 0.66; P<0.0001 and its inverse correlation with plasma albumin levels (Rho –0.62; P<0.0001 were found. High Ang2 concentrations turned out to be an independent predictor of severe liver dysfunction, as well as hepatic encephalopathy and renal impairment. Ang2 possessed the highest diagnostic and prognostic potential among three studied angiogenesis-related molecules.

    Hepatic encephalopathy (HE) is a complex neuropsychiatric syndrome characterized by central neural depression which may develop in both acute and chronic liver diseases. Its pathogenesis is not clearly understood and its main cause(s) is not yet known. The relations between several cytokines and HE pathogenesis were evaluated in many studies. In this study, we aimed to investigate the role of TNF--α, IL-6 and IL-8 in the pathogenesis of HE . Furthermore, the relation between the severity of HE and the levels of these cytokines was assessted. Methods: fourty patients with liver cirrhosis [20 patients with clinical findings of HE (group 3) and 20 without any symptoms of HE (group 2)] and 20 healthy controls (group 1) were included in this study. Serum TNF--α, IL-6 and IL-8 levels of patients and control subjects were studied using competitive enzyme immunoassay method (EIA). Results: There were statistically significant difference between serum TNF--α. IL-6 and IL-8 levels of patients with liver cirrhosis and healthy subjects, and between patients with and without HE. There was a positive correlation between the severity of liver cirrhosis according to Child-Pugh classification and cytokine levels. The severity of HE (grade 1-4) was closely related with cytokine levels, especially TNF-α. On the other hand, there was no relation between cytokine levels and the etiological factors

    To compare the clinical results of BRTO in the gastric varices with those of TIPS. From January 2004 to March 2006, eight patients who had been followed up for more than 1 month after BRTO were enrolled in this study. This study compared the clinical efficacy of BRTO with than of TIPS in 13 patients who had undergone TIPS from January 2000 to March 2006. The change in laboratory parameters before and after each procedure and the incidence of rebleeding, encephalopathy, asictes and varices were analyzed after each procedure. In the BRTO group, the level of albumin increased, and the levels of ammonia and the Child-Pugh score decreased. The TIPS group showed no improvement in the liver function. In the BRTO group, the gastric varices were eradicated in 7 patients. Gastric variceal rebleeding and encephalopathy did not occur. However, the esophageal varices worsened in 6 patients. In the TIPS group, rebleeding (n = 4), encephalopathy (n = 7) and a worsening of the gastric (n = 5) or esophageal varices (n = 2) occurred. BRTO improves the metabolic activity of the liver and has a lower incidence of encephalopathy. Hence, BRTO is a good alternative to TIPS in the gastric varices accompanied by a gastrorenal shunt although a treatment for a worsening of the esophageal varices may be needed after BRTO

    The prevalence of hepatopulmonary syndrome (HPS) and its influence on survival before and after liver transplantation (LT) remain controversial. Additionally, the chronology of post-LT reversibility is unclear. This study prospectively analyzed 316 patients with cirrhosis who were evaluated for LT in 2002-2007; 177 underwent LT at a single reference hospital. HPS was defined by a partial pressure of arterial oxygen (PaO2 ) position and positive contrast echocardiography. The prevalence of HPS was 25.6% (81/316 patients), and most patients (92.6%) had mild or moderate HPS. High Child-Pugh scores and the presence of ascites were independently associated with HPS. Patients with and without HPS did not significantly differ in LT waiting list survival (mean 34.6 months vs. 41.6 months, respectively; log-rank, p = 0.13) or post-LT survival (mean 45 months vs. 47.6 months, respectively; log-rank, p = 0.62). HPS was reversed in all cases within 1 year after LT. One-fourth of the patients with cirrhosis who were evaluated for LT had HPS (mostly mild to moderate); the presence of HPS did not affect LT waiting list survival. HPS was always reversed after LT, and patient prognosis did not worsen. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Tacrolimus (TAC) is the cornerstone of immunosuppressive regimen in liver transplantation (LT). Its pharmacokinetics is characterized by a high interpatient and intrapatient variability (IPV) leading to an unpredictable dose-response relationship. The aim of our study was to evaluate the impact of TAC IPV (IPV) on graft and patient outcomes after LT. We retrospectively analyzed 812 LT recipients treated with TAC. The IPV of TAC concentrations was estimated by calculating the coefficient of variation (CV) of whole blood trough concentrations. Patients were categorized in 2 groups: low IPV (CV < 40%) and high IPV (CV ≥ 40%). There were significantly more neurologic complications (31.2% vs 16.6%, P < 0.001), cardiovascular complications (19.7% vs 9.7%, P < 0.001), and acute renal failure requiring dialysis (8.5% vs 2.2%, P < 0.001) in the high CV group than in the low CV group. Moreover, graft survival was significantly poorer in the high CV group (hazard ratio, 1.42; 95% confidence interval, 1.04-1.95; P = 0.03). A pretransplantation elevated Model for End-Stage Liver Disease score (P < 0.001) and Child-Pugh grade (P < 0.001) were identified as risk factors for presenting a high CV. A high CV of TAC concentrations was found to be predictive of TAC-related toxicity and poorer survival.

    Full Text Available Although the adrenal glands are not common sites of metastasis from hepatocellular carcinoma (HCC, this metastasis can be met in patients with advanced HCC in some clinical settings. However, the effectiveness of radiotherapy against such metastases is unclear. Therefore, we performed the present multi-institutional study to investigate tumor response, overall survival (OS, treatment-related toxicity, and prognostic factors after radiotherapy. We retrospectively reviewed 134 patients who completed a planned radiotherapy for their adrenal metastases. Complete response was noted in 6 (4.3%, partial response in 48 (34.0%, and stable disease in 78 patients (55.3%. The median OS was 12.8 months, and the 1-, 2-, and 5-year OS rates were 53.1%, 23.9%, and 9.3%, respectively. Grade 3 anorexia occurred in 2 patients, grade 3 diarrhea in 1, and grade 3 fatigue in 1. Multivariate analyses revealed that the following factors had significant effects on OS: controlled intrahepatic tumor; controlled extrahepatic metastasis; and Child-Pugh class A. Although patients with adrenal metastasis from HCC had poor OS, radiotherapy provided an objective response rate of 38.3% and disease stability of 93.6%, with minimal adverse events. Therefore, radiotherapy for these patients could represent a good treatment modality, especially for patients with controlled intrahepatic tumors, controlled extrahepatic metastasis, and good hepatic function.

    Objective: To investigate the clinical results of combined TIPSS and azygoportal disconnection for portal hypertension in controlling and preventing esophageal variceal bleeding. Methods: From Oct. 1996 to Dec. 2001, 60 patients with portal hypertension were admitted to authors' department because of variceal bleeding and submitted to the treatment with the combination TIPSS and azygoportal disconnection. According to Child-Pugh classification, 11 patients were in class A, 37 in class B, and 12 in class C. 41 patients showed mild ascites and 8 with severe ascites. The mild and severe esophageal varices were proven by upper digestive barium meal. The procedure was divided into two stages; first, TIPSS procedure with the stent of diameter 0.8 cm and length 6-7 cm was successfully in planted in all patients, second, all patients underwent azygoportal disconnection two weeks later after TIPSS. Results: After the combination TIPSS and azygoportal disconnection, the recent complications included three cases with bleeding at operative fields, one case with infradiaphragmatic abscess and seven with slight encephalopathy. No rebleeding of esophageal varices and death occurred during the treatment. During the follow-up of 1-5 years, the rates of shunt occlusion, rebleeding and death were 11.9%, 3.5% and 7.0% respectively. Conclusions: The combination TIPSS and azygoportal disconnection is an efficient therapeutic methods for portal hypertension

    AIMS: The hepatic venous pressure gradient is a major prognostic factor in portal hypertension but its measurement is complex and requires invasive angiography. This study investigated the relationship between the hepatic venous pressure gradient and a number of Doppler measurements, including the arterial acceleration index. METHOD: We measured the hepatic venous pressure gradient in 50 fasting patients at hepatic venography. Immediately afterwards, a duplex sonographic examination of the liver was performed at which multiple measurements and indices of the venous and arterial hepatic vasculature were made. RESULTS: Hepatic arterial acceleration was correlated directly with the hepatic venous pressure gradient (r = 0.83, P < 0.0001) and with the Child-Pugh score (r = 0.63, P < 0.0001). An acceleration index cut-off value of 1 m.s{sup -2} provided a positive predictive value of 95%, a sensitivity of 65% and a specificity of 95% for detecting patients with severe portal hypertension (hepatic venous pressure gradient > 12 mmHg). A correlation between the hepatic venous pressure gradient and the congestion index of the portal vein velocity (r = 0.45,P = 0.01) and portal vein velocity (r = 0.40,P = 0.044), was also noted. CONCLUSION: Measuring the hepatic arterial acceleration index may help in the non-invasive evaluation of portal hypertension. Tasu, J.-P. et al. (2002)

    Background: The objective behind this study was to determine that Assessment for Re-treatment with Transarterial chemoembolization (ART) score is really applicable in patients with hepatocellular carcinoma. Methods: A cross sectional observational study was conducted on all patients with hepatocellular carcinoma of intermediate stage and undergone ≥2 Transarterial chemoembolization. ART score was assessed before and after each session of Transarterial chemoembolization. Multi-logistic regression analysis was performed to compare the final outcome of patients with ART score of ≥2.5 into groups with two and more than two Trans-arterial chemo-embolization sessions. Results: A total of 100 HCC patients were recruited for final analysis. Our study participants consisted of total 100 HCC patients. Mean Child Pugh score was 6.1±0.95. In our study, most of the study participants (n=63) had ART score of less than 1.5 as compared to ART score >2.5 (n=37). A significant proportion of patients with ART score of 2.5, p-value<0.001. Patients with ART score of more than 2.5 did not show any survival benefit after having 3rd or 4th Trans-arterial chemo-embolization session, p=0.47. Conclusions: Our study findings suggest that those HCC patients who receive multiple sessions of TACE with a low ART score have more favourable outcomes with increased survival rate. (author)

    The explosive growth in Earth observational data in the recent decade demands a better method of interoperability across heterogeneous systems. The Earth science data system community has mastered the art in storing large volume of observational data, but it is still unclear how this traditional method scale over time as we are entering the age of Big Data. Indexed search solutions such as Apache Solr (Smiley and Pugh, 2011) provides fast, scalable search via keyword or phases without any reasoning or inference. The modern search solutions such as Googles Knowledge Graph (Singhal, 2012) and Microsoft Bing, all utilize semantic reasoning to improve its accuracy in searches. The Earth science user community is demanding for an intelligent solution to help them finding the right data for their researches. The Ontological System for Context Artifacts and Resources (OSCAR) (Huang et al., 2012), was created in response to the DARPA Adaptive Vehicle Make (AVM) programs need for an intelligent context models management system to empower its terrain simulation subsystem. The core component of OSCAR is the Environmental Context Ontology (ECO) is built using the Semantic Web for Earth and Environmental Terminology (SWEET) (Raskin and Pan, 2005). This paper presents the current data archival methodology within a NASA Earth science data centers and discuss using semantic web to improve the way we capture and serve data to our users.

    Transarterial chemoembolization (TACE) is established as bridging therapy of HCC listed for transplantation (LT). CT-guided brachytherapy (CTB) has not been evaluated as a bridging concept. We compared CTB and TACE for bridging before LT in HCC patients. Twelve patients with HCC received LT after CTB (minimal tumour dose, 15-20 Gy). Patients were matched (CTB:TACE, 1:2) by sex, age, number and size of lesions, and underlying liver disease with patients who received TACE before transplantation. Study endpoints were extent of necrosis at histopathology and recurrence rate after OLT. There were no significant differences between the CTB and TACE groups regarding Child-Pugh category (p = 0.732), AFP (0.765), time on waiting list (p = 0.659), number (p = 0.698) and size (p = 0.853) of HCC lesions, fulfilment of Milan-criteria (p = 0.638), or previous liver-specific treatments. CTB achieved higher tumour necrosis rates than TACE (p = 0.018). The 1- and 3-year recurrence rate in the CTB group was 10 and 10 % vs. TACE, 14 and 30 % (p = 0.292). Our data show comparable or even better response and post-LT recurrence rates of CTB compared to TACE for treating HCC in patients prior to LT. CTB should be further evaluated as an alternative bridging modality, especially for patients not suited for TACE. (orig.)

    Full Text Available The importance of Power Hardware-in-the-Loop (PHIL experiments is rising more and more over the last decade in the field of power system and components testing. Due to the bidirectional exchange between virtual and physical systems, a true-to-reality interface is essential; however, linking several dynamic systems, stability issues can challenge the experiments, the components under test, and the individuals performing the experiments. Over the time, several interface algorithms (IA have been developed and analyzed, each having different advantages and disadvantages in view of combining virtual simulations with physical power systems. Finally, IA are very specific to the kind of PHIL experiment. This paper investigates the operational range of several IA for specific PHIL setups by calculations, simulations, and measurements. Therefore, a selection of the mainly used respectively optimized IA is mathematically described. The operational range is verified in a PHIL system testing environment. Furthermore, in order to study the influence of different PHIL setups, according to software and hardware impedance, different tests using linear and switching amplifiers are performed.

    56%/35%/7%, P<0.001. The serum levels of ALP (HR=1.653, 95%CI:1.001-2.729,P=0.049 and GGT (HR = 1.949, 95%CI:1.296-2.930,P=0.001 before treatment were closely associated with the progression-free survival of patients with primary liver cancer after radiofrequency ablation. There were more male patients with abnormal ALP than the female patients, and the patients with abnormal ALP had high incidence rates of poor Child-Pugh classification and ascites. In the patients with abnormal GGT (>45 U/L, there was a high proportion of patients with poor Child-Pugh classification, late tumor stages, and a tumor size of ≥5 cm and a high incidence rate of hepatic encephalopathy. ConclusionThe serum levels of ALP and GGT before treatment can be used to predict the prognosis of patients with primary liver cancer after radiofrequency ablation and have certain guiding significance for the long-term survival of patients with primary liver cancer after radiofrequency ablation.

    urinary debit <500 ml/24h within the first three days post-transplant. Univariate analysis and multivariate logistic regression were done. RESULTS: All transplants were performed with grafts from deceased donors. Sixty patients (39.2% had acute kidney injury. Age, body mass index, Child-Turcotte-Pugh, urea, hypertension, and preoperative serum creatinine were higher in the acute kidney injury group. During the intraoperative period, the group acute kidney injury had more reperfusion syndrome, transfusion of red blood cells, fresh frozen plasma and platelets. Postoperatively, the duration of mechanical ventilation and postoperative creatinine levels were also variable, with significant differences for the group of acute kidney injury. After logistic regression, the reperfusion syndrome, the class C of the Child-Turcotte-Pugh and postoperative serum creatinine showed differences. CONCLUSION: Acute kidney injury after orthotopic liver transplantation without conventional venovenous bypass is a common disorder, but with good prognosis. Reperfusion syndrome, serum creatinine postoperatively and Child C are factors associated with acute kidney injury after orthotopic liver transplantation without conventional venovenous bypass.

    2009-01-01

    Philip Solomon, one of the pioneers and leading researchers in molecular astrophysics, died on 30 April 2008 at his apartment on the upper west side of Manhattan after a battle with cancer. His pioneering research included both theoretical and very extensive observational studies of stellar atmospheres, interstellar molecules, high redshift galaxies, and the Earth's stratosphere. Phil was Distinguished Professor at The State University of New York [SUNY], Stony Brook, where he had been since 1974. Phil was born on 29 March 1939 in Manhattan, New York City, to Nat and Betty Solomon. Nat Solomon was a labor organizer and a printer. Phil attended the University of Wisconsin, where he received his BS in 1959 and where he met his future wife Sheila who was studying art. His Ph.D., "On the Role of Light Molecules in Astrophysics," was also from the University of Wisconsin under the guidance of Art Code and Bob Bless. After postdoctoral positions at Princeton and lectureships at Columbia and the University of California, San Diego, Phil spent two years as a Professor at the University of Minnesota. After two years at the Institute for Advanced Study in Princeton, he came to SUNY, Stony Brook, as Professor of Astronomy in the Department of Earth and Space Sciences. In 1988 Phil was selected as a Humboldt Senior Distinguished Scientist, and, in 1999, he was honored with the rank of Distinguished Professor at SUNY. Phil took sabbatical and other leaves at Churchill College and the Institute of Astronomy, Cambridge; the Institute for Advanced Study; l'Ecole Normale Superieure, Paris; Institut d'Astrophysique, Paris; and the Institut de Radioastronomie Millimetrique [IRAM], France. Phil published more than 160 papers and supervised seven Ph.D. students. He served on numerous review, visiting, and advisory panels. Phil's first theoretical research focused on opacity and abundance of light molecules such as H2, CO, and CN in stellar atmospheres, but then shifted quickly to the

    Phil and I started our careers on somewhat similar scientific paths. I had an undergraduate degree in physics from Swarthmore College and a Ph.D. degree in physics from Yale for research in the field for ultraviolet spectroscopy. Phil received an undergraduate degree in Physics from Oberlin College, joined the Yale Physics Department in 1954, and transferred to the new Biophysics Department in 1955. We began our interactions then by virtue of the fact that Phil had to take a Laboratory Course in Experimental Physics, one part of which was spectroscopy in which I was the instructor. One of my principal interests was in the effects of different wavelengths of ultraviolet (UV) radiation on proteins, viruses and bacterial cells. So what was more natural than for Phil to dream up a Ph.D. research project to investigate the effects of different wavelengths of UV on macromolecular synthesis in Escherichia coli. I became his mentor with expertise in UV, whereas he did most of the microbiological/biochemical work. Thus began a collaboration and a communicating friendship, the latter going on for 50 years. That communication was essential in elucidating some of the important steps in nucleotide excision repair-a field in which Phil is a pre-eminent scholar and investigator

    Open cholecystectomy is associated with considerable morbidity and mortality in cirrhotic patients. Laparoscopic cholecystectomy may offer a better option because of the magnification available and the availability of newer instruments like the ultrasonic shears. We present our experience of 265 laparoscopic cholecystectomies and attempt to identify the difficulties encountered in this group of patients. Between 1991 and 2005, 265 cirrhotic patients of Child-Pugh Classification A and B, with symptomatic gallstones, were subjected to laparoscopic cholecystectomy. We describe here our tailored approach and our techniques of subtotal cholecystectomy. Features of acute cholecystitis were present in 35.1% of the patients, and 64.9% presented with chronic cholecystitis. In 81.5% of the patients, the diagnosis of cirrhosis was established preoperatively. In 8.3% of the patients, a fundus first method was adopted when the hilum could not be approached despite additional ports. Modified subtotal cholecystectomy was performed in a total of 206 patients. Mean operative time in the subtotal cholecystectomy group was 72 minutes; in the standard group, it was 41 minutes. There was no mortality. In 15% of patients, postoperative deterioration in liver function occurred. Worsening of ascites, port site infection, port site bleeding, intraoperative hemorrhage, bilious drainage, and stone formation in the remnant were the other complications encountered. Laparoscopic cholecystectomy is a safe and effective treatment for calculous cholecystitis in cirrhotic patients. Appropriate modification of subtotal cholecystectomy should be practiced, depending on the risk factors present, to avoid complications.

    Pure laparoscopic liver resection (PLLR) has been reported to be as safe and effective as open liver resection (OLR) for liver lesions, and it is associated with less intraoperative blood loss, shorter hospital stay, and lower complication rate. However, studies comparing PLLR with OLR in elderly patients were limited. The aim of this study was to analyze the short-term outcome of PLLR versus OLR for primary liver carcinoma (PLC) in elderly patients.Between January 2008 and October 2014, 30 consecutive elderly patients (≥70 years) who underwent PLLR for PLC were included into analysis. Sixty patients who received OLR for PLC during the same study period were also included as a case-matched control group. Patients were well matched in terms of age, sex, comorbid illness, Child Pugh class, American Society of Anesthesiologists grade, tumor size, tumor location, and extent of hepatectomy.No significant differences were observed with regard to patient preoperative baseline status, median tumor size (Group PLLR 4.0 cm vs Group OLR 5.0 cm, P = 0.125), tumor location, extent of hepatectomy, and operation time (Group PLLR 133 minutes vs Group OLR 170 minutes, P = 0.073). Compared with OLR, the PLLR group displayed a significantly less frequent Pringle maneuver application (10.0% vs 70.0%, P PLC is as safe and feasible as OLR, but with less blood loss, shorter hospital stay, and lower hospitalization cost for selected elderly patients.

    Membranous obstruction is the most common cause of Budd-Chiari syndrome in Orientals. Recently, percutaneous transluminal balloon angioplasty (PTBA) has been successfully applied as a treatment of membranous obstruction. We evaluated etiologies and clinical manifestations in our cases and the usefulness of PTBA. Twelve cases of Budd-Chiari syndrome were analyzed. 50.3 years was the average age of the cases (ranging from 37 to 67 years). Major symptoms or signs were superficial collateral vessels on the chest or the abdomen in 6 cases, ascites in 3, abdominal pain in 4, hepatomegaly in 4, splenomegaly in 3, melena or hematemesis in 2, and leg edema in 2. Upper gastrointestinal endoscopy showed esophageal varices in 6 cases and two of these 6 cases had gastric varices. Of 8 cases with liver cirrhosis, 4 were classified as Child-Pugh class A and 4 as B. Four patients with cirrhosis had concurrent hepatocellular carcinoma including 1 patient who was HBs Ag positive. Etiologies were membranous obstruction in 11 cases and protein C deficiency in 1 case. The main site of obstruction was IVC in 8 and hepatic vein in 4. PTBA was successfully performed in 8 cases of membranous obstruction. During the mean follow-up period of 27.6 months (12-40 months), there were no reobstructions except in 2 cases. The most common cause of Budd-Chiari syndrome in our cases was membranous obstruction of IVC. Percutaneous transluminal balloon angioplasty is a very useful treatment method.

    Full Text Available Surgery is the primary curative option in patients with hepatocellular carcinoma (HCC. Current prognostic models for HCC are developed on datasets of primarily patients with advanced cancer, and may be less relevant to resectable HCC. We developed a postoperative nomogram, the Singapore Liver Cancer Recurrence (SLICER Score, to predict outcomes of HCC patients who have undergone surgical resection.Records for 544 consecutive patients undergoing first-line curative surgery for HCC in one institution from 1992-2007 were reviewed, with 405 local patients selected for analysis. Freedom from relapse (FFR was the primary outcome measure. An outcome-blinded modeling strategy including clustering, data reduction and transformation was used. We compared the performance of SLICER in estimating FFR with other HCC prognostic models using concordance-indices and likelihood analysis.A nomogram predicting FFR was developed, incorporating non-neoplastic liver cirrhosis, multifocality, preoperative alpha-fetoprotein level, Child-Pugh score, vascular invasion, tumor size, surgical margin and symptoms at presentation. Our nomogram outperformed other HCC prognostic models in predicting FFR by means of log-likelihood ratio statistics with good calibration demonstrated at 3 and 5 years post-resection and a concordance index of 0.69. Using decision curve analysis, SLICER also demonstrated superior net benefit at higher threshold probabilities.The SLICER score enables well-calibrated individualized predictions of relapse following curative HCC resection, and may represent a novel tool for biomarker research and individual counseling.

    Full Text Available ObjectiveTo compare clinical efficacy and recurrence between surgical resection and radiofrequency ablation (RFA in the treatment of small hepatocellular carcinoma (HCC. MethodsThe clinical data of 97 patients with small HCC, who underwent surgical resection or RFA as the initial treatment in The First Hospital of Jilin University from January 2002 to December 2008, were collected. Sixty-three cases, who survived 2 years after treatment, were followed up; of the 63 cases, 34 underwent surgical resection, and 29 underwent RFA. The recurrence of these patients was analyzed retrospectively. The measurement data were analyzed by chi-square test. The Cox regression analysis was used for determining the risk factors for recurrence. The log-rank test was used for disease-free survival (DFS difference analysis. ResultsThe 3-month, 1-year, and 2-year intrahepatic recurrence rates for the patients who underwent surgical resection were 15%, 38%, and 64%, respectively, versus 21%, 35%, and 45% for those who underwent RFA, without significant differences between the two groups of patients. The intrahepatic recurrence after initial treatment was not significantly associated with treatment method, sex, age, Child-Pugh grade, tumor size, number of nodules, presence of cirrhosis, and alpha-fetoprotein level. There was no significant difference in DFS between the two groups of patients. ConclusionRFA produces a comparable outcome to that by surgical resection in the treatment of small HCC. RFA holds promise as a substitute for surgical resection.

    Full Text Available Hepatocellular carcinoma (HCC, one of the most common malignancies with high prevalence and mortality rate, usually results in poor prognosis and limited survival. A comprehensive analysis on the number and location of tumors, Child-Pugh grade, and Barcelona Clinic Liver Cancer stage will help the development of suitable treatment programs and improve prediction of prognosis. A majority of patients are complicated by cirrhosis, enlarged tumor, multiple lesions, vascular invasion, and even cancer embolus in the portal vein. With the growth of knowledge about the radiation tolerance of normal tissue and the advances in radiotherapy techniques, radiotherapy has become an important tool for step-down therapy and adjuvant therapy for liver cancer. Proton beam therapy (PBT is emerging as a novel radiotherapy for the management of HCC, which, benefiting from the effect of Bragg Peak from PBT, effectively decreases the toxicity of traditional radiotherapies to the liver and does little harm to the uninvolved liver tissue or the surrounding structures while intensifying the destruction in targeted malignant lesions. Furthermore, several previous studies on the treatment of HCC with PBT revealed excellent local control. The distinctive biophysical attributes of PBT in the treatment of HCC, as well as the available literature regarding clinical outcomes and toxicity of using PBT for HCC, are reviewed. Current evidence provides limited indications for PBT, which suggests that further study on the relationship between liver function and PBT is required to gain further insight into its indication and standardization.

    Refractory hepatic encephalopathy (HE) frequently develops in patients with cirrhosis and portal-systemic shunt. Recently, patients with refractory HE associated with portal-systemic shunt have been treated with interventional radiology. We describe a promising new treatment for portal-systemic shunt, ligation of the patent paraumbilical vein (PUV) after partial splenic embolization, in patients with refractory HE. Four patients with cirrhosis (3 women and 1 man; mean age, 56 years) and refractory HE due to a patent PUV were studied. Patency of the PUV had recurred in 1 patient after primary occlusion by interventional radiological procedures. The Child-Pugh class was B in 2 patients and C in 2. Before the present treatment, all patients had been hospitalized at least 3 times because of recurrent HE. Partial splenic embolization was performed in all patients to decrease portal venous pressure before surgery. Surgical ligation of the patent PUV was performed under epidural anesthesia. The patent PUV was carefully skeletonized and doubly ligated. Esophageal varices were evaluated with upper gastrointestinal endoscopy before and after surgery. The mean follow-up duration was 15.8 months. After ligation, there were no clinically significant complications. Esophageal varices were unchanged. The serum ammonia level was higher before surgery (162.3 +/- 56.4 mug/dL, mean +/- SD) than after surgery (41.8 +/- 20.2 mug/dL; p=0.0299). No patient had symptoms of HE. Ligation of the patent PUV is an effective treatment for patients with refractory HE.

    Patients with chronic hepatitis C who achieve a sustained viral response after pegylated interferon therapy have a reduced risk of hepatocellular carcinoma, but the risk after treatment with direct-acting antivirals is unclear. We compared the rates of early development of hepatocellular carcinoma after direct-acting antivirals and after pegylated interferon therapy. We retrospectively analysed 785 patients with chronic hepatitis C who had no history of hepatocellular carcinoma (211 treated with pegylated interferon, 574 with direct-acting antivirals) and were followed up for at least 24 weeks after antiviral treatment. De novo hepatocellular carcinoma developed in 6 of 574 patients receiving direct-acting antivirals and in 1 of 211 patients receiving pegylated interferon. The cumulative incidence of early hepatocellular carcinoma development did not differ between the treatment groups either for the whole cohort (1.05% vs 0.47%, P = .298) or for those patients with Child-Pugh Class A cirrhosis (3.73% vs 2.94%, P = .827). Multivariate analysis indicated that alpha-fetoprotein level >9.5 ng/mL at the time of end-of-treatment response was the only independent risk factor for early development of hepatocellular carcinoma in all patients (P hepatocellular carcinoma did not differ between patients treated with pegylated interferon and those treated with direct-acting antivirals and was associated with the serum alpha-fetoprotein level at the time of end-of-treatment response. © 2018 John Wiley & Sons Ltd.

    No standard second-line treatments are available for hepatocellular carcinoma patients who fail sorafenib therapy. We assessed the safety and efficacy of metronomic capecitabine after first-line sorafenib failure. Retrospective analysis of consecutive hepatocellular carcinoma patients receiving metronomic capecitabine between January 2012 and November 2014. The primary end-point was safety, secondary end-point was efficacy, including time-to-progression and overall survival. Twenty-six patients (80% Child-Pugh A, 80% Barcelona Clinic Liver Cancer stage C) received metronomic capecitabine (500 mg/bid). Median treatment duration was 3.2 months (range 0.6-31). Fourteen (53%) patients experienced at least one adverse event. The most frequent drug-related adverse events were bilirubin elevation (23%), fatigue (15%), anaemia (11%), lymphoedema (11%), and hand-foot syndrome (7.6%). Treatment was interrupted in 19 (73%) for disease progression, in 4 (15%) for liver deterioration, and in 1 (3.8%) for adverse event. Disease control was achieved in 6 (23%) patients. Median time-to-progression was 4 months (95% confidence interval 3.2-4.7). Median overall survival was 8 months (95% confidence interval 3.7-12.3). Metronomic capecitabine was well tolerated in hepatocellular carcinoma patients who had been treated with sorafenib. Preliminary data show potential anti-tumour activity with long-lasting disease control in a subgroup of patients that warrants further evaluation in a phase III study.

    Since the liver plays a key metabolic role, volatile organic compounds in the exhaled breath might change with type and severity of chronic liver disease (CLD). In this study we analysed breath-prints (BPs) of 65 patients with liver cirrhosis (LC), 39 with non-cirrhotic CLD (NC-CLD) and 56 healthy controls by the e-nose. Distinctive BPs characterized LC, NC-CLD and healthy controls, and, among LC patients, the different Child-Pugh classes (sensitivity 86.2% and specificity 98.2% for CLD vs healthy controls, and 87.5% and 69.2% for LC vs NC-CLD). Moreover, the area under the BP profile, derived from radar-plot representation of BPs, showed an area under the ROC curve of 0.84 (95% CI 0.76-0.91) for CLD, of 0.76 (95% CI 0.66-0.85) for LC, and of 0.70 (95% CI 0.55-0.81) for decompensated LC. By applying the cut-off values of 862 and 812, LC and decompensated LC could be predicted with high accuracy (PPV 96.6% and 88.5%, respectively). These results are proof-of-concept that the e-nose could be a valid non-invasive instrument for characterizing CLD and monitoring hepatic function over time. The observed classificatory properties might be further improved by refining stage-specific breath-prints and considering the impact of comorbidities in a larger series of patients.

    Full Text Available Transarterial chemoembolization (TACE is usually followed by hepatic dysfunction. We evaluated the effects of L-carnitine on post-TACE impaired liver functions. Methods. 53 cirrhotic hepatocellular carcinoma patients at Osaka Medical College were enrolled in this study and assigned into either L-carnitine group receiving 600 mg oral L-carnitine daily or control group. Liver functions were evaluated at pre-TACE and 1, 4, and 12 weeks after TACE. Results. The L-carnitine group maintained Child-Pugh (CP score at 1 week after TACE and exhibited significant improvement at 4 weeks after TACE (P<0.01. Conversely, the control group reported a significant CP score deterioration at 1 week (P<0.05 and 12 weeks after TACE (P<0.05. L-carnitine suppressed serum albumin deterioration at 1 week after TACE. There were significant differences between L-carnitine and control groups regarding mean serum albumin changes from baseline to 1 week (P<0.05 and 4 weeks after TACE (P<0.05. L-carnitine caused prothrombin time improvement from baseline to 1, 4 (P<0.05, and 12 weeks after TACE. Total bilirubin mean changes from baseline to 1 week after TACE exhibited significant differences between L-carnitine and control groups (P<0.05. The hepatoprotective effects of L-carnitine were enhanced by branched chain amino acids combination. Conclusion. L-carnitine maintained and improved liver functions after TACE.

    Chronic liver disease (CLD) is characterized by numerous metabolic alterations resulting in the clinical picture of malnutrition or even cachexia and contributing to complications such as hepatic encephalopathy and ascetics. In view of these alternations, this study was conducted to investigate the role of serum insulin-like growth factor-I (IGF-I) and ghrelin in CLD with or without cirrhosis and evaluate their relationships with liver functions and clinical complications. Serum IGF-I levels were very highly significantly lowered (P< 0.0001) in hepatitis C virus (HCV) patients and in hepatocellular carcinoma (HCC) patients than in the control group. However, serum ghrelin levels were significantly elevated in HCV and in HCC patients when compared with controls (P< 0.05). IGF-I significantly decreased with every stage of cirrhosis according to Child-Pugh classification. In contrast, serum ghrelin levels were significantly elevated in Child C liver cirrhosis compared to non cirrhotic patients (Child A and Child B cirrhosis). IGF-I levels inversely correlated with prothrombin time (PT.), total bilirubin and positively correlated with serum albumin. While serum ghrelin correlated with clinical complications of CLD. No correlations were found between IGF-I and ghrelin in all studied groups, however, both inversely correlated with a-feto protein (AFP) in HCC patients. We conclude that IGF-I.and ghrelin can predict the diagnosis and prognosis of patients with severe CLD as they have potential relationships with hepatic failure and HCC.

    Chronic liver disease (CLD) is characterized by numerous metabolic alterations resulting in the clinical picture of malnutrition or even cachexia and contributing to complications such as hepatic encephalopathy and ascetics. In view of these alternations, this study was conducted to investigate the role of serum insulin-like growth factor-I (IGF-I) and ghrelin in CLD with or without cirrhosis and evaluate their relationships with liver functions and clinical complications. Serum IGF-I levels were very highly significantly lowered (P< 0.0001) in hepatitis C virus (HCV) patients and in hepatocellular carcinoma (HCC) patients than in the control group. However, serum ghrelin levels were significantly elevated in HCV and in HCC patients when compared with controls (P< 0.05). IGF-I significantly decreased with every stage of cirrhosis according to Child-Pugh classification. In contrast, serum ghrelin levels were significantly elevated in Child C liver cirrhosis compared to non cirrhotic patients (Child A and Child B cirrhosis). IGF-I levels inversely correlated with prothrombin time (PT.), total bilirubin and positively correlated with serum albumin. While serum ghrelin correlated with clinical complications of CLD. No correlations were found between IGF-I and ghrelin in all studied groups, however, both inversely correlated with a-feto protein (AFP) in HCC patients. We conclude that IGF-I.and ghrelin can predict the diagnosis and prognosis of patients with severe CLD as they have potential relationships with hepatic failure and HCC

    Objective: To determine the incidence and risk factors associated with needle tract seeding after percutaneous microwave ablation (MWA) of liver cancer under ultrasound guidance. Materials and methods: Over a 14-year period, a total of 1462 patients with 2530 malignant nodules were treated by MWA. The influence of age, sex, Child-pugh classification, tumor size, tumor position, previous biopsy, insertion number and antenna type on the risk of neoplastic seeding was assessed. The survival of seeding patients after the MWA was analyzed. Results: Eleven patients with 12 nodules (0.47% per tumor, 0.75% per patient) were identified with needle tract seeding with an interval time of 6–37 (median 10) months after MWA. The mean size of the seeding nodule was 2.3 ± 0.7 cm (from 1.3 to 3.9 cm). Only previous biopsy was significantly associated with neoplastic seeding (P = 0.02). All the seeding lesions were successfully treated by resection, MWA, radiation or high intensity focus ultrasound. The median survival period of the 11 patients after the MWA was 36.0 months. The cumulative survival rates of the 11 patients after the MWA at 1-, 2-, 3-, 4- and 5-year were 90.9%, 72.7%, 62.3%, 31.2% and 15.6%, respectively. Conclusion: The results showed that the neoplastic seeding was a low risk complication of percutaneous MWA of liver cancer and was considered acceptable in general.

  18. Sarcopenia in the prognosis of cirrhosis: Going beyond the MELD score

    2015-01-01

    Estimating the prognosis of patients with cirrhosis remains challenging, because the natural history of cirrhosis varies according to the cause, presence of portal hypertension, liver synthetic function, and the reversibility of underlying disease. Conventional prognostic scoring systems, including the Child-Turcotte-Pugh score or model for end-stage liver diseases are widely used; however, revised models have been introduced to improve prognostic performance. Although sarcopenia is one of the most common complications related to survival of patients with cirrhosis, the newly proposed prognostic models lack a nutritional status evaluation of patients. This is reflected by the lack of an optimal index for sarcopenia in terms of objectivity, reproducibility, practicality, and prognostic performance, and of a consensus definition for sarcopenia in patients with cirrhosis in whom ascites and edema may interfere with body composition analysis. Quantifying skeletal muscle mass using cross-sectional abdominal imaging is a promising tool for assessing sarcopenia. As radiological imaging provides direct visualization of body composition, it is useful to evaluate sarcopenia in patients with cirrhosis whose body mass index, anthropometric measurements, or biochemical markers are inaccurate on a nutritional assessment. Sarcopenia defined by cross-sectional imaging-based muscular assessment is prevalent and predicts mortality in patients with cirrhosis. Sarcopenia alone or in combination with conventional prognostic systems shows promise for a cirrhosis prognosis. Including an objective assessment of sarcopenia with conventional scores to optimize the outcome prediction for patients with cirrhosis needs further research. PMID:26167066

    Disturbance of the gut microbiota is common in liver cirrhosis (LC) patients, the underlying mechanisms of which are yet to be unfolded. This study aims to explore the relationship between small bowel transit (SBT) and gut microbiota in LC patients. Cross-sectional design was applied with 36 LC patients and 20 healthy controls (HCs). The gut microbiota was characterized by 16S rRNA gene sequencing. The Firmicutes/Bacteroidetes (F/B) ratio and the Microbial Dysbiosis index (MDI) were used to evaluate the severity of microbiota dysbiosis. The scintigraphy method was performed in patients to describe the objective values of SBT. Patients were then subdivided according to the Child-Pugh score (threshold = 5) or SBT value (threshold = 0.6) for microbiota analysis. LC patients were characterized by an altered gut microbiota; F/B ratios and MDI were higher than HC in both Child_5 (14.00 ± 14.69 vs. 2.86 ± 0.99, p gut microbiota between Child_ 5 and Child_5+ patients was inappreciable, but the SBT was relatively slower in Child_5+ patients (43 ± 26% vs. 80 ± 15%, p gut microbiota was observed between SBT_0.6- and SBT_0.6+ patients [Pr(> F ) = 0.0068, pMANOVA], with higher F/B ratios and MDI in SBT_0.6- patients (19.71 ± 16.62 vs. 7.33 ± 6.65, p gut microbiota abnormalities observed in patients with LC.

    Large spontaneous portosystemic shunts (SPSS) are seen in a subset of patients with liver disease and medically refractory recurrent/persistent hepatic encephalopathy (MRHE). Shunt occlusion has been shown to improve clinical outcomes. We retrospectively analyzed patient characteristics, SPSS attributes, procedural features, baseline clinical and investigational parameters, neurological outcomes, adverse effects (procedure and portal hypertension related), and risk factors predicting outcomes in liver disease patients undergoing shunt occlusion procedure for MRHE. Between October 2016 and July 2017, 21 patients (Child-Pugh score, CTP 6 to 13) with mean model of end-stage liver disease (MELD) and MELD-sodium scores 15.7 and 19.3 respectively with MRHE [3-cirrhotic Parkinsonism (CP)] were diagnosed to have single or multiple large SPSSs. A total of 29 shunts were occluded (1 surgical, 20 non-surgical). Recurrent and persistent HE and CP markedly improved in the short (n=20, 1 to 3 months), intermediate (n=12, 3 to 6 months), and long (n=7, 6 to 9 months) follow up. None had spontaneous or persistent HE at a median follow up 105 (30 to 329) days (p11 predicted mortality post shunt occlusion (p=0.04). Embolization of large SPSS in liver disease patients with MRHE and modestly preserved liver function is safe and efficacious and associated with improved quality of life and can function as a bridge to liver transplantation in accurately selected patients.

    Full Text Available CONTEXT: Most patients subjected to liver transplantation presents hypersplenism, which is reversed after the operation. However, some patients remain with moderate to intense hypersplenism. OBJECTIVES: To study the effect of liver transplantation on platelet count in patients with hypersplenism. METHOD: Of a total of 233 patients who underwent liver transplantation, 162 were excluded from the present study because of occurrence of steroid-resistant rejection, absence of hypersplenism before the transplantation, absence of follow-up for at least 2 years or incomplete exams data. The electronic study protocols of the remaining 71 patients were reviewed to determine the demographics, etiology of cirrhosis, and results of pathologic examination of the explanted liver. Serial platelet count was obtained from the study protocol on the day before liver transplantation and 1, 2, 4, and 6 months and 1 year after liver transplantation. Statistical analysis was performed using the Student's t-test, chi-square test, and Spearman's correlation test. RESULTS: Posttransplant platelet count at all time intervals was significantly higher than the pretransplant value (P100,000/mm³ in 58 patients (81.7% 1 month after liver transplantation. Twelve patients (16.9% remained with thrombocytopenia 1 year after liver transplantation. Three patients (4.2% had recurrence of thrombocytopenia within 1 year after liver transplantation. There was no correlation between pretransplant platelet count and the Child-Pugh class or the MELD score. CONCLUSION: Liver transplantation reverses hypersplenism in most patients.

  2. Definition of ACLF and inclusion criteria for extra-hepatic organ failure.

    A prominent characteristic of ACLF is rapid hepatic disease progression with subsequent extra-hepatic organ failure, manifesting as either hepatic coma or hepatorenal syndrome, which is associated with a high mortality rate in a short time. The APASL definition mainly emphasizes recognizing patients with hepatic failure. These patients may subsequently develop extra-hepatic multisystem organ failure leading to high mortality. It is therefore worthwhile to identify the short interim period between the development of liver failure and the onset of extra-hepatic organ failure, the potential therapeutic 'golden window.' Interventions during this period may prevent the development of complications and eventually change the course of the illness. Organ failure is suggested to be a central component of ACLF and may behave differently from chronic decompensated liver disease. Clear and practical criteria for the inclusion of organ failure are urgently needed so that patients with these life-threatening complications can be treated in a timely and appropriate manner. Recent studies suggested that the scoring systems evaluating organ failure [acute physiology, age and chronic health evaluation (APACHE) and sequential organ failure assessment (SOFA) scores] work better than those addressing the severity of liver disease [Child-Pugh and model of end-stage liver disease (MELD) scores] in ACLF. However, a key problem remains that the former scoring systems are reflective of organ failure and not predictive, thus limiting their value as an early indication for intervention.

    The Clauss fibrinogen method and thrombin clotting time (TCT) are still routinely used in patients with cirrhosis to define fibrinogen concentration and clotting potential. The thromboelastometric functional fibrinogen FIBTEM assay evaluates the strength of fibrin-based clots in whole blood, providing information on both quantitative deficit and fibrin polymerization disorders. To compare these three methods of assessing fibrinogen in patients with cirrhosis of different aetiologies, characterized by impairment in fibrinogen concentration as well as functional aberrance. Sixty patients with alcoholic and 24 patients with cholestatic cirrhosis were included (Child-Pugh score (CPs)A, n=24; B, n=32; C, n=28). All parameters were compared with those from a control group. Maximum clot firmness (MCF) in the FIBTEM test was assessed in regard to its relevance in detection of qualitative fibrinogen disorders in comparison with results obtained by standard measurement methods, i.e. the Clauss fibrinogen method and TCT. With increased cirrhosis severity, fibrinogen and FIBTEM-MCF levels significantly declined (p=0.002), while TCT was significantly prolonged (p=0.002). In all CPs groups, fibrinogen strongly correlated with FIBTEM-MCF (r=0.77, r=0.72, r=0.74; pmeasurement in cirrhotic patients, especially in evaluating fibrin polymerization disorders in these patients. Further studies are needed to evaluate the usefulness of this assay in predicting bleeding complications in cirrhotic patients as well as monitoring replacement treatment.

    Full Text Available Abstract Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma in vitro. In a phase II trial, we investigated safety and efficacy including selection criteria for best response in advanced or metastasised hepatocellular carcinoma. Methods 44 patients (84 % male, median age 69 years not suitable or refractory to conventional therapy received thymostimulin 75 mg subcutaneously five times per week for a median of 8.2 months until progression or complete response. 3/44 patients were secondarily accessible to local ablation or chemoembolisation. Primary endpoint was overall survival, secondary endpoint tumor response or progression-free survival. A multivariate Cox's regression model was used to identify variables affecting survival. Results Median survival was 11.5 months (95% CI 7.9–15.0 with a 1-, 2- and 3-year survival of 50%, 23% and 9%. In the univariate analysis, a low Child-Pugh-score (p = 0.01, a low score in the Okuda- and CLIP-classification (p Conclusion Outcome in our study rather depended on liver function and intrahepatic tumor growth (presence of liver cirrhosis and Okuda stage in addition to response to thymostimulin, while an invasive HCC phenotype had no influence in the multivariate analysis. Thymostimulin could therefore be considered a safe and promising candidate for palliative treatment in a selected target population with advanced hepatocellular carcinoma, in particular as component of a multimodal therapy concept.

    To evaluate the therapeutic effect of transcatheter arterial embolization (TAE) as a first treatment course for hypervascular hepatocellular carcinoma (HCC), using nationwide web-based multicenter data in Korea. Eight hundred eighty eight HCC patients who were registered in the internet homepage of primary liver cancer registry (www.plcr.or.kr) from August 2003 to August 2005 were enrolled in this study, and they were investigated till February 2007. The patients were divided into three groups according to the following treatments after first TAE; TAE only, TAE + SL (any surgical resection, transplantation or percutaneous ablation followed), TAE + RC (any radiation therapy or chemotherapy followed). The clinical and tumor characteristics, embolization factors and survival periods were analyzed. The 5-year survival rates of the groups of TAE only, TAE + SL and TAE + RC were 21.6%, 57.4%, and 13.1%, respectively. In all cases and in the TAE only group, more selective and complete embolization increased survival rates. There were tendencies that as smaller tumor and the tumor in earlier stage, more selective and complete embolizations were performed in the TAE only group, and independent prognostic factors of this group were Child-Pugh classification, tumor size and Modified 4th UICC stage. This study is the first nationwide multicenter analysis for TAE using an online registration system in Korea. Selective and complete TAE increases patient's survival, and decisive combined treatment after TAE such as surgical resection, transplantation or percutaneous ablation increases patient's survival.

    The principal aim of our study was to investigate the usefulness of serum protein and circulating mRNA of insulin-like growth factor-1 (IGF-1) as a diagnostic and prognostic tool in hepatocellular carcinoma (HCC). Fifty-four HCC patients and age- and sex-matched 20 healthy controls were enrolled into this study. Pretreatment serum IGF-1 and IGF-1 mRNA were determined by the solid-phase sandwich ELISA and quantitative RT-PCR method, respectively. The median age at diagnosis was 60 years, range 36-77 years; where majority of group were male (n = 48, 88.8%). All patients had cirrhotic history. Forty-six percent (n = 25) of patients had Child-Pugh score A, 30% (n = 16) had score B or C. All of the patients were treated with local therapies and none of them received sorafenib. The baseline serum IGF-1 mRNA levels were significantly higher in HCC patients than in the control group (p = 0.04), whereas no significant difference was observed for IGF-1 protein levels between the two group (p = 0.18). Patients with history of HBV infection, who were not treated, and who received multiple palliative treatment for HCC had higher serum IGF-1 mRNA levels (p = 0.03, 0.03, and 0.05, respectively). Poor performance status (p IGF-1 nor serum IGF-1 mRNA had significantly adverse effect on survival (p = 0.53 and 0.42, respectively).

    In patients with hepatocellular carcinoma (HCC), gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) often identifies non-hypervascular hypointense hepatic nodules during the hepatobiliary phase, but their prognostic significance is unclear. We conducted a prospective observational study to investigate the impact of non-hypervascular hypointense hepatic nodules detected by Gd-EOB-DTPA-enhanced MRI on the outcome of patients with early-stage HCC. Post-treatment recurrence and survival rates were analyzed in 138 patients with non-recurrent, early-stage HCC [Barcelona Clinic Liver Cancer (BCLC) stage 0 or A] and Child-Pugh A liver function according to the presence of non-hypervascular hypointense nodules on pretreatment Gd-EOB-DTPA-enhanced MRI. Non-hypervascular hypointense hepatic nodules were detected in 51 (37.0%) patients with early-stage HCC on pretreatment Gd-EOB-DTPA-enhanced MRI. Recurrence rates were significantly higher in patients with non-hypervascular hypointense nodules (p DTPA-enhanced MRI was independently associated with an increased recurrence rate, independent of tumor progression or treatment (p = 0.0005). The survival rate was significantly lower in patients with non-hypervascular hypointense nodules on Gd-EOB-DTPA-enhanced MRI (p = 0.0108). In patients with early-stage typical HCC (BCLC 0 or A), the presence of concurrent non-hypervascular hypointense hepatic nodules in the hepatobiliary phase of pretreatment Gd-EOB-DTPA-enhanced MRI is an indicator of higher likelihood of recurrence after treatment and may be a marker for unfavorable outcome.

    Objective: To study the abnormal findings and metabolic alterations of the brain in chronic hepatic disease with MRI and 1 H magnetic resonance spectroscopy ( 1 H-MRS) for better understanding the clinical significance of pallidal hyperintensity and the role in the diagnosis and treatment of hepatic encephalopathy (HE). Methods: Brain MRI and 1 H-MRS examination were performed in 50 patients with chronic hepatic disease and 20 healthy volunteers. The pallidus index (PI) was calculated and the height of resonance peaks of Glx was measured. The correlation between PI and Child/Pugh classification, and the association between blood ammonia and the spectroscopic alterations were studied. Pre-and post-therapeutic comparative study was also conducted in 5 cases with chronic HE. Results: PI was gradually increased from healthy volunteers to patients with chronic hepatitis and liver cirrhosis (1.01± 0.04, 1.06±0.09, and 1.18±0.09), and the differences in PI value among them were significant (F=22.294, P 1 -weighted MRI disappeared and the abnormal metabolic alterations returned to normal range 5 to 6 months after successful liver transplantation. However, the normalization of 1 H-MRS alterations preceded the disappearance of pallidal hyperintensities. Conclusion: PI can be an index of reference for liver dysfunction. Glx is more sensitive than blood ammonia in detecting the brain dysfunction. MRI and 1 H-MRS are reliable techniques in the diagnosis and evaluation of therapy for hepatic encephalopathy. (authors)

    To evaluate the cardiovascular and splanchnic hemodynamic changes in patients with liver cirrhosis and to compare with those of the normal controls using doppler ultrasonography. A total of 129 patients including 23 of Child-Pugh class A, 24 of class A, 24 of class B, 30 of class C, and 52 of the control group were included. Cardiac output (CO), systemic vascular resistance index (SVRI), and blood flow and pulsatility index (PI) of the superior mesenteric artery (SMA) were evaluated and compared among each groups. CO and SMA blood flow in the cirrhotic group were significantly higher than those in the control group, and the increase in CO and SMA blood flow showed a statistically significant correlation with the degree of liver dysfunction (p<0.01). SVRI and SMA PI reflecting vascular resistance in the cirrhotic group were significantly lower than those in the control group, and the decrease in SVRI and SMA PI also showed a statistically significant correlation with the degree of liver dysfunction (p<0.01). SMA blood flow showed a statistically significant inverse relationship with SMA PI (R{sup 2}=0.230). Hyperdynamic circulatory changes such as increases in CO and splanchnic blood flow were present in patients with liver cirrhosis. These changes may contribute to the development and maintenance of the portal hypertension due to an increase in portal blood flow an increase in portal blood flow.

    Liver transplantation in patients with liver cirrhosis, portal vein thrombosis, and cavernous transformation of the portal vein, is a complex procedure with high possibility of liver graft dysfunction. It is performed in 2-19% of all liver transplants, and has a significantly high mortality rate in the post-operative period. Other procedures to maintain portal perfusion have been described, however there are no reports of liver graft perfusion using right gastroepiploic vein. A 20 year-old female diagnosed with cryptogenic cirrhosis, with a Child-Pugh score of 7 points (class "B"), and MELD score of 14 points, with thrombosis and cavernous transformation of the portal vein, severe portal hypertension, splenomegaly, a history of upper gastrointestinal bleeding due to oesophageal varices, and left renal agenesis. The preoperative evaluation for liver transplantation was completed, and the right gastroepiploic vein of 1-cm diameter was observed draining to the infrahepatic inferior vena cava and right suprarenal vein. An orthotopic liver transplantation was performed from a non-living donor (deceased on January 30, 2005) using the Piggy-Back technique. Portal vein perfusion was maintained using the right gastroepiploic vein, and the outcome was satisfactory. The patient was discharged 13 days after surgery. Liver transplantation was performed satisfactorily, obtaining an acceptable outcome. In this case, the portal perfusion had adequate blood flow through the right gastroepiploic vein.

    Renal failure is a common finding in patients undergoing orthotopic liver transplantation. The aim of the present study was to evaluate the incidence, prognostic value of pre, intra and postoperative factors and severity of renal dysfunction in patients who undergo liver transplantation. Therefore, the records of 38 consecutive adult patients were reviewed. Renal failure was defined arbitrarily as an increase in creatinine (> 1.5 mg/dl) and/or blood urea (> 80 mg/dl). Three patients were excluded of the final analysis (1 acute liver failure and 2 with a survival lower than 72 hs.) Twenty one of the 35 patients has renal failure after orthotopic liver transplantation. Six of these episodes developed early, having occurred within the first 6 days. Late renal impairment occurred in 15 patients within the hospitalization (40 +/- 10 days) (Mean +/- SD). In he overall series, liver function, evaluated by Child-Pugh classification, a higher blood-related requirements and cyclosporine levels were observed more in those who experienced renal failure than those who did not (p renal failure was related with preoperative (liver function) and intraoperative (blood requirements) factors and several causes (nephrotoxic drugs and graft failure) other than cyclosporine were present in patients who developed late renal impairment. No mortality. No mortality was associated with renal failure. We conclude that renal failure a) is a common finding after liver transplantation, b) the pathogenesis of this complication is multifactorial and, c) in not related with a poor outcome.

    Full Text Available Transmission of malaria parasites relies on the formation of a specialized blood form called the gametocyte. Gametocytes of the human pathogen, Plasmodium falciparum, adopt a crescent shape. Their dramatic morphogenesis is driven by the assembly of a network of microtubules and an underpinning inner membrane complex (IMC. Using super-resolution optical and electron microscopies we define the ultrastructure of the IMC at different stages of gametocyte development. We characterize two new proteins of the gametocyte IMC, called PhIL1 and PIP1. Genetic disruption of PhIL1 or PIP1 ablates elongation and prevents formation of transmission-ready mature gametocytes. The maturation defect is accompanied by failure to form an enveloping IMC and a marked swelling of the digestive vacuole, suggesting PhIL1 and PIP1 are required for correct membrane trafficking. Using immunoprecipitation and mass spectrometry we reveal that PhIL1 interacts with known and new components of the gametocyte IMC.

    Full Text Available El 27 de Agosto de 1995, Vernon Pugh, presidente de la comisión de la International Rugby Board (IRB para el amateurismo, declaró que el Rugby pasaba a ser un deporte libre. Se terminaba de esta forma con más de un siglo de amateurismo declarado en este deporte, y se terminaba también con una década de debates sobre el conocido shamateurismo, o profesionalismo encubierto, en el cual los jugadores no cobraban por jugar pero si por el trabajo, ya fuera real o ficticio, que le proporciona el club que defendían. En ese año, terminaba el anacronismo de un deporte de finales del S.XX sometido a reglas de la Inglaterra victoriana. ¿Como se pudo llegar a dicha situación? Dunning y Sheard argumentan que el fenómeno del amateurismo en el Rugby en el S.XIX fue un instrumento de diferenciación social complejo y que debe ser analizado desde un punto de vista histórico y sociopolítico. En esta línea, Bádenas expone que la aristocracia británica del S. XIX utilizó el interés creciente por la cultura griega antigua para atribuir unos valores al deporte practicado en aquella época de forma que se conceptualizó el deporte como una actividad lúdica propia de una élite social. Para lograrlo, ensalzaron los valores de un deporte amateur griego (que no existió como tal concepto y realzaron aquellos textos que criticaban la profesionalización de los deportistas y sus efectos sobre el deporte. Teóricos británicos, como Mahaffy atribuían al deporte griego antiguo unos valores que coincidían con el prototipo de gentlemen deportista de la época victoriana.-----------------------------------------------------------------The August 27, 1995, Vernon Pugh, chairman of the committee of the International Rugby Board (IRB for amateurism, said the Rugby happened to be a free sport.

    Prosopis tamarugo Phil. is a strict phreatophyte tree species endemic to the "Pampa del Tamarugal", Atacama Desert. The extraction of water for various uses has increased the depth of the water table in the Pampa aquifers threatening its conservation. This study aimed to determine the effect of the groundwater table depth on the water relations of P. tamarugo and to present thresholds of groundwater depth (GWD) that can be used in the groundwater management of the P. tamarugo ecosystem. Three levels of GWD, 11.2 ± 0.3 m, 10.3 ± 0.3 m, and 7.1 ± 0.1 m, (the last GWD being our reference) were selected and groups of four individuals per GWD were studied in the months of January and July of the years 2011 through 2014. When the water table depth exceeded 10 m, P. tamarugo had lower pre-dawn and mid-day water potential but no differences were observed in minimum leaf stomatal resistance when compared to the condition of 7.1 m GWD; the leaf tissue increased its δ(13)C and δ(18)O composition. Furthermore, a smaller green canopy fraction of the trees and increased foliage loss in winter with increasing water table depth was observed. The differences observed in the physiological behavior of P. tamarugo trees, attributable to the ground water depth; show that increasing the depth of the water table from 7 to 11 m significantly affects the water status of P. tamarugo. The results indicate that P. tamarugo has an anisohydric stomatal behavior and that given a reduction in water supply it regulates the water demand via foliage loss. The growth and leaf physiological activities are highly sensitive to GWD. The foliage loss appears to prevent the trees from reaching water potentials leading to complete loss of hydraulic functionality by cavitation. The balance achieved between water supply and demand was reflected in the low variation of the water potential and of the variables related to gas exchange over time for a given GWD. This acclimation capacity of P. tamarugo after

    Full Text Available Cytomegalovirus (CMV infections in liver transplant recipients are common and result in significant morbidity and mortality. Intravenous ganciclovir or oral valganciclovir are the standard treatment for CMV infection. The present study investigates the efficacy of oral valganciclovir in CMV infection as a preemptive treatment after liver transplantation.Between 2012 and 2013, 161 patients underwent liver transplantation at Samsung Medical Center. All patients received tacrolimus, steroids, and mycophenolate mofetil. Patients with CMV infection were administered oral valganciclovir (VGCV 900mg/day daily or intravenous ganciclovir (GCV 5mg/kg twice daily as preemptive treatment. Stable liver transplant recipients received VGCV.Eighty-three patients (51.6% received antiviral therapy as a preemptive treatment because of CMV infection. The model for end-stage liver disease (MELD score and the proportions of Child-Pugh class C, hepatorenal syndrome, and deceased donor liver transplantation in the CMV infection group were higher than in the no CMV infection group. Sixty-one patients received GCV and 22 patients received VGCV. The MELD scores in the GCV group were higher than in the VGCV group, but there were no statistical differences in the pretransplant variables between the two groups. AST, ALT, and total bilirubin levels in the GCV group were higher than in the VGCV group when CMV infection occurred. The incidences of recurrent CMV infection in the GCV and VGCV groups were 14.8% and 4.5%, respectively (P=0.277.Oral valganciclovir is feasible as a preemptive treatment for CMV infection in liver transplant recipients with stable graft function.

    Spontaneous bacterial peritonitis is an infectious complication with a negative impact on survival of patients with cirrhosis. To analyze the short- and long-term survival after a first episode of bacterial peritonitis and the associated prognostic factors. This was a retrospective, multicenter study of patients admitted to hospital for spontaneous bacterial peritonitis between 2008 and 2013. Independent variables related to mortality were analyzed by logistic regression. The prognostic power of the Child Pugh Score, the Model for End-Stage Liver Disease (MELD) and the Charlson index was analyzed by ROC curve. A total of 159 patients were enrolled, 72% were males with a mean age of 63.5 years and a mean MELD score of 19 (SD ± 9.5). Mortality at 30 and 90 days and one and two years was 21%, 31%, 55% and 69%, respectively. Hepatic encephalopathy (p = 0.008, OR 3.5, 95% CI 1.4-8.8) and kidney function (p = 0.026, OR 2.7, 95% CI 1.13-16.7) were independent factors for short- and long-term mortality. MELD was a good marker of short- and long-term survival (area under the curve [AUC] 0.7: 95% CI 1.02-1.4). The Charlson index was related to long-term mortality (AUC 0.68: 95% CI 0.6-0.77). Short- and long-term mortality of spontaneous bacterial peritonitis is still high. The main prognostic factors for mortality are impairment of liver and kidney function. MELD and the Charlson index are good markers of survival.

    Full Text Available Background. Serum cystatin C (CysC was proposed as an effective reflection of the glomerular filtration rate (GFR. However, its role in patients with liver cirrhosis has not been extensively verified especially in the detection of early RI. Patients and Methods. Seventy consecutive potential candidates for living donor liver transplantation with serum creatinine (Cr <1.5 mg/dL were included. CysC, Cr, and estimated GFR [creatinine clearance (CCr, Cockcroft-Gault formula (C-G, MDRD equations with 4 and 6 variables, CKD-EPI-Cr, CKD-EPI-CysC, and CKD-EPI-Cr-CysC] were all correlated to isotopic GFR. Early RI was defined as GFR of 60–89 mL/min/1.73 m2. Results. Patients were 25.7% and 74.3% Child-Pugh classes B and C, respectively. GFR was ≥90, 60–89, and 30–59 mL/min/1.73 m2 in 31.4%, 64.3%, and 4.3% of the patients, respectively. All markers and equations, except C-G, were significantly correlated to GFR with CKD-EPI-Cr-CysC formula having the highest correlation (r = 0.474 and the largest area under the ROC curve (0.808 for discriminating early RI. At a cutoff value of 1.2 mg/L, CysC was 89.6% sensitive and 63.6% specific in detecting early RI. Conclusion. In patients with liver cirrhosis, CysC and CysC-based equations showed the highest significant correlation to GFR and were measures that best discriminated early RI.

    To investigate the current status of portal vein thrombosis (PVT) in Japan, the Clinical Research Committee of the Japan Society of Portal Hypertension undertook a questionnaire survey. A questionnaire survey of 539 cases of PVT over the previous 10 years was carried out at institutions affiliated with the Board of Trustees of the Japan Society of Portal Hypertension. The most frequent underlying etiology of PVT was liver cirrhosis in 75.3% of patients. Other causes included inflammatory diseases of the hepatobiliary system and the pancreas, malignant tumors, and hematologic diseases. The most frequent site was the main trunk of the portal vein (MPV) in 70.5%, and complete obstruction of the MPV was present in 11.5%. Among the medications for PVT, danaparoid was given to 45.8%, warfarin to 26.2%, heparin to 17.3%, and anti-thrombin III to 16.9%. Observation of the course was practiced in 22.4%. Factors contributing to therapeutic efficacy were implementation of various medications, thrombi localized to either the right or left portal vein only, non-complete obstruction of the MPV and Child-Pugh class A liver function. A survival analysis showed that the prognosis was favorable with PVT disappearance regardless of treatment. The questionnaire survey showed the current status of PVT in Japan. Any appropriate medication should be given to a patient with PVT when PVT is recognized. It is necessary to compile a large amount of information and reach a consensus on safe and highly effective management of PVT. © 2017 The Japan Society of Hepatology.

  4. Ascitic microbiota composition is correlated with clinical severity in cirrhosis with portal hypertension.

    Full Text Available Identification of pathogenic bacteria in ascites correlates with poor clinical outcomes. Ascites samples are commonly reported culture-negative, even where frank infection is indicated. Culture-independent methods have previously reported bacterial DNA in ascites, however, whether this represents viable bacterial populations has not been determined. We report the first application of 16S rRNA gene pyrosequencing and quantitative PCR in conjunction with propidium monoazide sample treatment to characterise the viable bacterial composition of ascites. Twenty five cirrhotic patients undergoing paracentesis provided ascites. Samples were treated with propidium monoazide to exclude non-viable bacterial DNA. Total bacterial load was quantified by 16S rRNA Q-PCR with species identity and relative abundance determined by 16S rRNA gene pyrosequencing. Correlation of molecular microbiology data with clinical measures and diagnostic microbiology was performed. Viable bacterial signal was obtained in 84% of ascites samples, both by Q-PCR and pyrosequencing. Approximately 190,000 ribosomal pyrosequences were obtained, representing 236 species, including both gut and non gut-associated species. Substantial variation in the species detected was observed between patients. Statistically significant relationships were identified between the bacterial community similarity and clinical measures, including ascitic polymorphonuclear leukocyte count and Child-Pugh class. Viable bacteria are present in the ascites of a majority of patients with cirrhosis including those with no clinical signs of infection. Microbiota composition significantly correlates with clinical measures. Entry of bacteria into ascites is unlikely to be limited to translocation from the gut, raising fundamental questions about the processes that underlie the development of spontaneous bacterial peritonitis.

    Full Text Available Objective To investigate the pathogenesis, diagnostic keys, and treatment of hepatogenous diarrhea. MethodsSixty-two patients with hepatogenous diarrhea were assigned to three levels of treatment. Patients given level-one treatment received live combined Clostridium butyricum and Bifidobacterium powder for regulating intestinal flora; patients given level-two treatment received montmorillonite powder for constriction, adsorption, and stopping diarrhea and compound diphenoxylate for inhibiting intestinal peristalsis; patients given level-three treatment received somatostatin for reducing portal pressure. Total bilirubin, albumin, total bile acid, prothrombin time, platelet count, spleen thickness, spleen length, splenic vein width, and portal vein width, as well as routine stool test and stool culture, were measured before treatment, and the times of diarrhea and time of onset were determined before and after treatment. Measurement data were expressed as P50(P25-P75, and statistical analysis was performed using the Spearman rank correlation coefficient. ResultsHepatogenous diarrhea was mostly seen in patients with decompensated liver cirrhosis. The higher the Child-Pugh score, the severer the diarrhea and the higher the susceptibility to diarrhea. Hepatogenous diarrhea had no specific clinical manifestations. Mild or moderate diarrhea was treated mainly by improving liver function, regulating intestinal flora, and inhibiting intestinal peristalsis, while severe diarrhea mainly by reducing portal pressure. ConclusionThe pathogenesis of hepatogenous diarrhea is complex, without specificity for the diagnosis. The key to therapy is to treat the primary liver disease, regulate intestinal flora, reduce portal pressure, and somatostatin shows good efficacy for severe diarrhea.

    To evaluate long-term survival rates and prognostic factors of patients with hepatocellular carcinoma after TAE. 225 patients with hepatocellular carcinoma treated with TAE between January 1988 and December 1994 were studied. Hepatocellular carcinoma was diagnosed either histologically(n=13) or clinically on the basis of findings characteristic for hepatocellular carcinoma obtained using such as diagnostic imaging methods such as ultrasonography, CT, MRI, and angiography as well as on the basis of high serum alpha-fetoprotein level(n=212). TAE was carried out between one and six times(mean, 1.4 time) using a mixture of lipiodol and Adriamycin, together with Gelfoam. Cumulative survival rates from the day of the first TAE were obtained by the Kaplan-Meier method. Parameters likely to influence the prognosis were subjected to univariate analysis using the log-rank test Cumulative survival rates at the end of the first, second, third, fourth, and fifth year were 55.9%, 32.6%, 21.9%, 17.9%, and 15.0%, respectively. The mean survival time was 727{+-}76 days. Several factors, including Child-Pugh classification, Okuda's stage, tumor size, presence of portal vein invasion by tumor, of arterio-portal shunt, and of extrahepatic metastases, catheter selection level, and number of TAE showed significant correlation with the outcome. Degrees of Lipiodol accumulation in a tumor on follow up CT were also correlated with survival rates. TAE is an effective measure for prolonging the patient's life expectancy and evaluation of prognostic factor is helpful for prognosis and in deciding on the optimal therapeutic modality.

    Purpose: The present study evaluates the influence of portal vein (PV) vs. inferior vena cava (IVC) tumor thrombosis sites on the effectiveness of external-beam radiation therapy (EBRT) in advanced hepatocellular carcinoma (HCC) with macrovascular invasion. Methods and Materials: We retrospectively reviewed 181 HCC patients with PV and/or IVC tumor thrombi who were referred for EBRT at our institution between 2000 and 2009. EBRT was designed to focus on the tumor thrombi with or without primary intrahepatic tumors to deliver a median total conventional dose of 50 Gy (range, 30-60 Gy). Predictors of survival were identified using univariate and multivariate analyses. Results: The median survival was 10.2, 7.4, 17.4, and 8.5 months for patients with PV branch, PV trunk, IVC, and PV plus IVC tumor thrombosis, respectively. Unfavorable pretreatment predictors were associated by multivariate analysis with lower albumin and higher {alpha}-fetoprotein levels, poorer Child-Pugh liver function classification, multiple intrahepatic foci, lymph node metastases, thrombus location, less chance to receive post-EBRT transarterial chemoembolization (TACE) and the two-dimensional EBRT technique. In comparison to patients with PV tumor thrombosis, patients with IVC thrombi had a higher occurrence of solitary intrahepatic lesions (p = 0.027), well-controlled intrahepatic tumors (p < 0.001), and a better response to EBRT (p < 0.001), and they were more likely to receive post-EBRT TACE (p = 0.033). Conclusions: In HCC, patients with IVC thrombus treated with EBRT had a better response rate and longer survival than those with PV thrombus.

    Objective: To determine the accuracy of serum alpha fetoprotein (AFP) for diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis. Study Design: Observational study. Place and Duration of Study: Department of Medicine, The King Edward Medical University, Lahore, from November 2007 to August 2011. Methodology: Consecutive patients, diagnosed with HCC by contrast enhanced CT, MRI or biopsy were included as cases. Patients of cirrhosis with no evidence of HCC were enrolled as controls. Demographic, laboratory and radiological data were recorded. Serum AFP was determined in all patients at outset and was analyzed using ROC curve for its accuracy in diagnosing HCC. Results: A total of 275 patients were included; of them 173 had HCC and 102 had cirrhosis. One hundred and thirty nine cases (80.3%) with HCC and 86 (84.3%) without HCC had cirrhosis due to HCV. Stage of liver disease, as determined by Child Turcotte Pugh (CTP) score, was comparable; mean CTP value 7.97 A +- 2.1A +- 2.21 in control group (p 0.41). Area under curve (AUC) for AFP was 0.85 (95%, CI: 0.80 - 0.90) with optimum cut off value of 20.85 ng/ml which showed 72.2% sensitivity, 86.2% specificity, 89.9% positive predictive value, 64.7% negative predictive value and 77.4% overall accuracy in diagnosing patients with HCC. Conclusion: Despite sub-optimal sensitivity, alpha fetoprotein is still a valid screening test for diagnosis of hepatocellular carcinoma till other more sensitive markers are developed. Till then, it should be used in conjunction with ultrasound. (author)

Treatment consisted of bortezomib, 1.3 mg/m2 IV bolus on days 1, 4, 8, and 11 of each 21-day treatment cycle. Eligibility included: no prior systemic chemotherapy, ECOG PS 0-2, Child-Pugh A or B, preserved hematologic, hepatic and neurologic function; prior liver-directed therapy was permitted. Results Thirty-five patients enrolled and received a median of 2 cycles of treatment (range 1–12). Overall, 24 and 4 patients had a maximum severity of grade 3 and 4 adverse events (AEs), respectively. No treatment related deaths occurred. Only thrombocytopenia (11%) was seen in greater than 10% of patients. One patient achieved a partial response, lasting 13 weeks during treatment and progressed 11.6 months later; two patients received treatment for greater than 6 months. Median time-to-progression was 1.6 months and median survival was 6.0 months. Conclusions This international, multicenter trial evaluated bortezomib as monotherapy in unresectable HCC patients. And, despite the lack of significant activity, this report serves as a baseline clinical experience for the development of future dual biologic approaches including bortezomib. PMID:20839030

    Liver fibrosis can progress to cirrhosis, which is considered a serious disease. The Child-Pugh score and the model of end-stage liver disease score have been established to assess residual liver function in patients with liver cirrhosis. The development of portal hypertension contributes to ascites, variceal bleeding and further complications in these patients. A transjugular intrahepatic portosystemic shunt (TIPS) is used to lower portal pressure, which represents a major improvement in the treatment of patients. Adipokines are proteins released from adipose tissue and modulate hepatic fibrogenesis. These proteins affect various biological processes that are involved in liver function, including angiogenesis, vasodilation, inflammation and deposition of extracellular matrix proteins. The best studied adipokines are adiponectin and leptin. Adiponectin protects against hepatic inflammation and fibrogenesis, and leptin functions as a profibrogenic factor. These and other adipokines are supposed to modulate disease severity in patients with liver cirrhosis. Consequently, circulating levels of these proteins have been analyzed to identify associations with parameters of hepatic function, portal hypertension and its associated complications in patients with liver cirrhosis. This review article briefly addresses the role of adipokines in hepatitis and liver fibrosis. Here, studies having analyzed these proteins in systemic blood in cirrhotic patients are listed to identify adipokines that are comparably changed in the different cohorts of patients with liver cirrhosis. Some studies measured these proteins in systemic, hepatic and portal vein blood or after TIPS to specify the tissues contributing to circulating levels of these proteins and the effect of portal hypertension, respectively.

    A wide variety of pulmonary conditions are found in cirrhotic patients and may compromise the pleura, diaphragm, parenchyma, and pulmonary vasculature, influencing the results of liver transplantation. To evaluate the pulmonary function (lung capacities, volumes, and gasometric study) of patients with liver cirrhosis awaiting liver transplantation. Cirrhotic patients, subdivided into 3 groups stratified by liver disease severity using the Child-Pugh-Turcotte score, were compared with a control group of healthy volunteers. In spirometry, the parameters evaluated were total lung capacity, forced volume in the first second, and the relationship between forced volume in the first minute and forced vital capacity. Blood gas analysis was performed. In the control group, arterial oxygenation was evaluated by peripheral oxygen saturation by pulse oximetry. Of the 55 patients (75% men, 51 ± 12.77 years), 11 were Child A (73% men, 52 ± 14.01 years), 23 were Child B (75% men, 51 ± 12.77 years), and 21 were Child C (95% men, 50 ± 12.09 years). The control group had 20 individuals (50% men, 47 ± 8.15 years). Pulmonary capacities and volumes by the parameters evaluated were within the normal range. Arterial blood gas analysis detected no hypoxemia, but a tendency to low partial gas pressure was noted. In this population of cirrhotic patients the parameters of spirometry were normal in relation to the lung capacities and volumes in the different groups. No hypoxemia was detected, but a tendency to hypocapnia in the blood gas was noted. Copyright © 2018. Published by Elsevier Inc.

    Hepatocellular carcinoma (HCC) represents the second leading cause of cancer-related death worldwide. The serpin peptidase inhibitor SERPINB5 is a tumour-suppressor gene that promotes the development of various cancers in humans. However, whether SERPINB5 gene variants play a role in HCC susceptibility remains unknown. In this study, we genotyped 6 SNPs of the SERPINB5 gene in an independent cohort from a replicate population comprising 302 cases and 590 controls. Additionally, patients who had at least one rs2289520 C allele in SERPINB5 tended to exhibit better liver function than patients with genotype GG (Child-Pugh grade A vs. B or C; P = 0.047). Next, haplotype blocks were reconstructed according to the linkage disequilibrium structure of the SERPINB5 gene. A haplotype “C-C-C” (rs17071138 + rs3744941 + rs8089204) in SERPINB5-correlated promoter showed a significant association with an increased HCC risk (AOR = 1.450 P = 0.031). Haplotypes “T-C-A” and “C-C-C” (rs2289519 + rs2289520 + rs1455555) located in the SERPINB5 coding region had a decreased (AOR = 0.744 P = 0.031) and increased (AOR = 1.981 P = 0.001) HCC risk, respectively. Finally, an additional integrated in silico analysis confirmed that these SNPs affected SERPINB5 expression and protein stability, which significantly correlated with tumour expression and subsequently with tumour development and aggressiveness. Taken together, our findings regarding these biomarkers provide a prediction model for risk assessment.

    Full Text Available Hepatic arterial infusion chemotherapy (HAIC is an option for treating advanced hepatocellular carcinoma (HCC. Because of the poor prognosis in HAIC non-responders, it is important to identify patients who may benefit from continuous HAIC treatment; however, there are currently no therapeutic assessment scores for this identification. Therefore, we aimed to establish a new therapeutic assessment score for such patients.We retrospectively analyzed 90 advanced HCC patients with elevated baseline alpha-fetoprotein (AFP and/or des-gamma-carboxy prothrombin (DCP levels and analyzed various parameters for their possible use as predictors of response and survival. AFP and DCP responses were assessed after half a course of HAIC (2 weeks; a positive-response was defined as a reduction of ≥ 20% from baseline.Multivariate analysis identified DCP response (odds ratio 16.03, p < 0.001 as an independent predictor of treatment response. In multivariate analysis, Child-Pugh class A (hazard ratio [HR] 1.99, p = 0.018, AFP response (HR 2.17, p = 0.007, and DCP response (HR 1.90, p = 0.030 were independent prognostic predictors. We developed an Assessment for Continuous Treatment with HAIC (ACTH score, including the above 3 factors, which ranged from 0 to 3. Patients stratified into two groups according to this score showed significantly different prognoses (≤ 1 vs. ≥ 2 points: median survival time, 15.1 vs. 8.7 months; p = 0.003.The ACTH score may be useful in the therapeutic assessment of HCC patients receiving HAIC.

    Background: According to the results of a number of phase 3 randomized studies, sorafenib is the only approved systemic therapy for advanced HCC; however the issue of high eco- Sorafenib nomic cost remains challenging; thus we have conducted this retrospective analysis of our HCC patients treated with sorafenib. Methods: HCC Shams University Hospitals, in the period between 2010 and 2012 were reviewed. Eligible patients were those who had received sorafenib for advanced HCC not eligible for or progressed after surgery or locoregional therapy. We investigated the impact of baseline clinico pathological factors (age, gender, child status, performance score, BCLC tumor stage, cause of chronic liver disease, median baseline alpha fetoprotein level and previous treatment received for HCC) on overall survival (OS) in an adjusted Cox regression model. Results: 41 patients were included in the analysis fulfilling the inclusion criteria. At a median follow up period of 13 months, the median PFS for the whole group was 4 months; the median OS for the whole group is 6.25 months. Multivariate analysis identified three baseline characteristics that were prognostic indicators for overall survival: ECOG performance status (median OS for ECOG 1 = 7.01 months and for ECOG 2 = 3.03 months), Child-Pugh status (median OS for child A = 12.04 months and for child B = 5.23 months), and median baseline levels of alpha-fetoprotein. Conclusions: In limited resource countries like Egypt, we suggest that the use of sorafenib for the treatment of advanced HCC cases should be restricted to a highly selected subgroup of patients with good performance and child A.

    Lipocalin 2 (LCN2) is induced in the injured liver and associated with inflammation. Aim of the present study was to evaluate whether serum LCN2 is a non-invasive marker to assess hepatic steatosis in patients with non-alcoholic fatty liver disease (NAFLD) or residual liver function in patients with liver cirrhosis. Therefore, LCN2 was measured by ELISA in serum of 32 randomly selected patients without fatty liver (controls), 24 patients with ultrasound diagnosed NAFLD and 42 patients with liver cirrhosis mainly due to alcohol. Systemic LCN2 was comparable in patients with liver steatosis, those with liver cirrhosis and controls. LCN2 negatively correlated with bilirubin in both cohorts. In cirrhosis, LCN2 was not associated with more advanced liver injury defined by the CHILD-PUGH score and model for end-stage liver disease score. Resistin but not C-reactive protein or chemerin positively correlated with LCN2. LCN2 levels were not increased in patients with ascites or patients with esophageal varices. Consequently, reduction of portal pressure by transjugular intrahepatic portosystemic shunt did not affect LCN2 levels. Hepatic venous blood (HVS), portal venous blood and systemic venous blood levels of LCN2 were similar. HVS LCN2 was unchanged in patients with end-stage liver cirrhosis compared to those with well-compensated disease arguing against increased hepatic release. Current data exclude that serum LCN2 is of any value as steatosis marker in patients with NAFLD and indicator of liver function in patients with alcoholic liver cirrhosis.

    Protein energy malnutrition frequently occurs in liver cirrhosis. Hand-grip strength according to Jamar is most reliable to predict protein energy malnutrition. We aimed to determine whether protein energy malnutrition affects complication risk. In 84 cirrhotics, baseline nutritional state was determined and subsequent complications prospectively assessed. Influence of potentially relevant factors including malnutrition (by Jamar hand-grip strength) on complication rates were evaluated with univariate analysis. Effect of malnutrition was subsequently evaluated by multivariate logistic regression with adjustment for possible confounders. Underlying causes of cirrhosis were viral hepatitis in 31%, alcohol in 26%, and other in 43%. Baseline Child-Pugh (CP) class was A, B, or C in 58, 35, and 7%, respectively. Energy and protein intake decreased significantly with increasing CP class, with shift from proteins to carbohydrates. At baseline, according to Jamar hand-grip strength, malnutrition occurred in 67% (n=56). Malnutrition was associated with older age and higher CP class (CP class A 57%, B 79%, C 100%) but not with underlying disease or comorbidity. Complications occurred in 18 and 48% in well-nourished and malnourished patients, respectively, (P=0.007) during 13 ± 6 months follow-up. In multivariate analysis, malnutrition was an independent predictor of complications, after correcting for comorbidity, age, and CP score (adjusted odds ratio 4.230; 95% confidence interval 1.090-16.422; P=0.037). In univariate analysis, mortality (4 vs. 18%; P=0.1) tended to be worse in malnourished patients, but this trend was lost in multivariate analysis. Malnutrition is an independent predictor of complications in cirrhosis.

  18. Model for End-stage Liver Disease and Organ Allocation in Liver Transplantation: Where Are We and Where Should We Go?

    Full Text Available The Child-Turcotte-Pugh (CTP score has been used for decades to measure the severity of chronic liver disease. Recent studies have shown that the model for end-stage liver disease (MELD more accurately predicts the short-and mid-term survival for patients with cirrhosis compared to the CTP system. MELD, which has 3 parameters (serum bilirubin, creatinine, and prothrombin time that need logarithmic transformation, has the advantage of a wide-range continuous scale and is more objective and less variable. The liver allocation system has changed from a status-based algorithm using the CTP score, to one using a continuous MELD severity score as a reference system to prioritize adult patients on the waiting list since 2002 in the USA. However, there are potential limitations of MELD. An intrinsic defect is that some important parameters, such as hepatic encephalopathy and ascites, which are common adverse complications in cirrhosis, are not included in MELD. It has been suggested to incorporate a low serum sodium level into the prognostic model to enhance the predictive ability. Moreover, the change of MELD over time may provide updated information for patients on the transplant waiting list. In summary, although there was encouraging evidence supporting the prognostic advantage of MELD, the optimal role of MELD in the setting of outcome assessment for cirrhotic patients needs more study. Appropriate modifications and fine tuning of MELD are necessary for determining the ranking status of patients on the waiting list, to avoid a futile transplantation and improve overall patient survival.

    Background and aims: The thalamus is a major relay and filter station in the central neural system. Some previous studies have suggested that the thalamus maybe implicated in the pathogenesis of hepatic encephalopathy. The aim of our study was to investigate changing thalamic volumes in cirrhotic patients with and without hepatic encephalopathy. Methods: Neuropsychological tests and structural MR scanning were performed on 24 cirrhotic patients, 23 cirrhotic patients with minimal hepatic encephalopathy, 24 cirrhotic patients during their first episode of overt hepatic encephalopathy, and 33 healthy controls. Voxel-based morphometry analysis was performed to detect gray matter morphological changes. The thalamus and whole brain volume were extrapolated. A receiver operating characteristic curve analysis of thalamic volumes was used to discriminate patients with minimal hepatic encephalopathy from those with hepatic cirrhosis. Results: Thalamic volume increased in a stepwise manner in patients with progressively worse stages of hepatic encephalopathy compared to healthy subjects. Additionally, a comparison of gray matter morphometry between patients with Child–Pugh grades A, B, or C and controls revealed a progression in thalamic volumes in parallel with the degree of liver failure. Moreover, thalamic volume was significantly correlated with the number connection test A time and digit-symbol test score in cirrhotic patients with minimal hepatic encephalopathy (r = 0.659, P = 0.001; r = −0.577, P = 0.004; respectively). The area under the receiver operating characteristic curve was 0.827 (P = 0.001). Conclusions: A significantly increased thalamic volume may be provide an objective imaging measure for predicting seizures due to minimal hepatic encephalopathy in cirrhotic patients

    Limited data exist on the outcomes of ritonavir-boosted paritaprevir with ombitasvir and dasabuvir (PrOD) ± ribavirin in a real-world setting. The aim of this study was to compare the efficacy and safety of PrOD-based therapy in hepatitis C genotype 1 patients with and without cirrhosis, and to explore pre-treatment factors predictive of sustained viral response (SVR) and serious adverse events (SAEs) on treatment. 451 patients with hepatitis C genotype 1 treated in 20 centres across Australia were included. Baseline demographic, clinical and laboratory information, on-treatment biochemical, virological and haematological indices and details on serious adverse events were collected locally. Cirrhosis was present in 340 patients (75.4%). Overall SVR was 95.1% with no differences in SVR between the cirrhosis and non-cirrhosis groups (94.7% versus 96.4%). SVR in subgenotypes 1a and 1b was 93.1% and 99.2%, respectively. On multivariate analysis, baseline bilirubin level and early treatment cessation predicted SVR. SAEs occurred in 10.9% of patients including hepatic decompensation (2.7%) and hepatocellular carcinoma (1.8%). On multivariate analysis of factors predictive of SAEs in the overall group, Child-Turcotte-Pugh (CTP) B was the only significant factor, while in those with cirrhosis, baseline albumin and creatinine levels were significant. In this large real-world cohort of HCV genotype 1 subjects, treatment with PrOD was highly effective and similar to clinical trials. Important determinants of reduced SVR include early cessation of therapy and baseline bilirubin concentration. SAEs were not infrequent with CTP B patients being at greatest risk.

    Full Text Available Abstract Background Studies have shown psychological distress in patients with cirrhosis, yet no studies have evaluated the laboratory and physiologic correlates of psychological symptoms in cirrhosis. This study therefore measured both biochemistry data and heart rate variability (HRV analyses, and aimed to identify the physiologic correlates of depression, anxiety, and poor sleep in cirrhosis. Methods A total of 125 patients with cirrhosis and 55 healthy subjects were recruited. Each subject was assessed through routine biochemistry, 5-minutes ECG monitoring, and psychological ratings of depression, anxiety, and sleep. HRV analysis were used to evaluate autonomic functions. The relationship between depression, sleep, and physiologic correlates was assessed using a multiple regression analysis and stepwise method, controlling for age, duration of illness, and severity of cirrhosis. Results Reduced vagal-related HRV was found in patients with severe liver cirrhosis. Severity of cirrhosis measured by the Child-Pugh score was not correlated with depression or anxiety, and only had a weak correlation with poor sleep. The psychological distress in cirrhosis such as depression, anxiety, and insomnia were correlated specifically to increased levels of aspartate aminotransferase (AST, increased ratios of low frequency to high frequency power, or reduced nonlinear properties of HRV (α1 exponent of detrended fluctuation analysis. Conclusions Increased serum AST and abnormal autonomic nervous activities by HRV analysis were associated with psychological distress in cirrhosis. Because AST is an important mediator of inflammatory process, further research is needed to delineate the role of inflammation in the cirrhosis comorbid with depression.

    This study aimed to objectively assess mean serum zinc levels and influence of age, gender and primary etiology of chronic liver disease (CLD) on these levels in a sample of Pakistani pediatric patients with decompensated CLD (DCLD). Methodology: It was a cross-sectional survey carried out at Combined Military Hospital, Lahore, from August 2013 to February 2014. Through non-probability consecutive sampling we included 100 cases belonging to both genders, fitting in the age-range of 1 - 12 years and having DCLD based on Child-Pugh classification score = 6. Patients with diarrhea, respiratory or urinary tract infection, liver tumors or receiving treatments with immune suppressants, antifungals, antivirals and zinc supplementation were excluded. Results After exclusion, off 74 cases, 58.1% were male. Majority belonged to the age group of 6 - 12 years (54.1%). Idiopathic DCLD was the most prevalent primary etiology (40.5%). Mean serum zinc levels (44.5 ± 4.7 mu g/dL) were significantly lower (p< 0.001) than the minimum normal serum zinc levels (65 micro g/dL). The mean serum zinc levels were lower significantly in children with idiopathic CLD as the primary etiology (p=0.012) and insignificantly in females and children belonging to the age group of 1- < 6 years (p= 0.08 and p= 0.59 respectively) Conclusion Mean serum zinc levels in our sample of pediatric patients with DCLD were significantly lower than the reference values for normal children, were lowest in children suffering from idiopathic CLD and were not dependent on gender and age.

    Treating patients with decompensated cirrhosis with direct-acting antiviral (DAA) therapy while on the waiting list for liver transplantation results in substantial improvement of liver function allowing 1 in 4 patients to be removed from the waiting list or delisted, as reported in a previous study promoted by the European Liver and Intestine Transplant Association (ELITA). The aim of this study was to report on clinical outcomes of delisted patients, including mortality risk, hepatocellular carcinoma development and clinical decompensation requiring relisting. One hundred and forty-two HCV-positive patients on the liver transplant waiting list for decompensated cirrhosis, negative for hepatocellular carcinoma, between February 2014 and June 2015 were treated with DAA therapy and were prospectively followed up. Forty-four patients (30.9%) were delisted following clinical improvement. This percentage was higher than in the original study because of a number of patients being delisted long after starting DAAs. The median Child-Pugh and MELD score of delisted patients was 5.5 and 9 respectively. Four patients were relisted, because of HCC diagnosis in 1 case and 3 patients developed ascites. One further patient died (2.4%) because of rapidly progressing hepatocellular carcinoma twenty-two months after delisting. Of the 70 patients who received a liver graft, 9 died (13%). Antiviral therapy allows for a long-term improvement of liver function and the delisting of one-third of treated patients with risk of liver-related complications after delisting being very low. © 2018 John Wiley & Sons A/S.

    To determine the long-term prognosis of hepatocellular carcinoma (HCC) after argon-helium cryoablation and identify the risk factors that predict metastasis and recurrence. A total of 156 patients with hepatitis B-related HCC less than 5 cm in diameter who underwent curative cryoablation were followed up prospectively for tumor metastasis and recurrence. Immunohistochemistry was used to analyze the expression of vascular endothelial growth factor (VEGF). HBV basal core promoter (BCP) and precore mutations were detected by DNA sequence analysis. Post-treatment prognostic factors influencing survival, tumor metastasis and recurrence were assessed by univariate and multivariate analyses. The variables included the expression of VEGF in HCC tissues, clinical and pathologic characteristics of patients, and HBV features (HBV DNA level, HBV genotype, BCP mutation). The median follow-up period of the 156 patients was 37 months (range 8-48 months). The 1-, 2-, and 3-year overall survival rates were 92, 82 and 64%, respectively. The 1-, 2-, and 3-year recurrence-free survival rates were 72, 56 and 43%, respectively. Eighty-five patients (54.5%) had tumor recurrence or metastasis. The multivariate analysis showed that Child-Pugh class and the expression of VEGF in HCC tissues could be used as independent prognostic factors for overall survival. Meanwhile, the expression of VEGF in HCC tissues and HBV BCP mutations were found to be independent prognostic factors for recurrence-free survival. Strong expression of VEGF in HCC tissues and HBV BCP mutations are important risk predictors for recurrence or metastasis of HCC smaller than 5 cm in diameter.

    Background: The diagnosis of bacterial infection in cirrhotic patients may be difficult, because of the absence of classical signs such as fever and raised white blood cell count. The role of C-reactive protein (CRP) in this context has not been clearly defined. Methods: Clinical and laboratory characteristics of 210 consecutive cirrhotic patients with (n=100) or without (n=110) bacterial infection were compared with a control group of non-cirrhotic patients with infection (n=106). Results: Significantly fewer patients with cirrhosis had a body temperature ≥37°C when presenting with bacterial infection (56% cirrhotic vs. 85.5% non-cirrhotic patients, P=0.01). Mean leukocyte count was 6.92 × 103/mm3 in patients with cirrhosis and infection, 5.75 × 103/mm3 (P=0.02) in cirrhotic patients without infection, and 11.28 × 103/mm3 in non-cirrhotic patients with infection (P10 mg/L indicated the presence of infection with a sensitivity of 68%, a specificity of 84.5% and an area under the receiver operating characteristic curve of 0.8197. CRP cutoff level differed according to the severity of the liver disease: Child-Pugh score (CPS) A: 21.3 mg/L, B: 17 mg/L, and C: 5.78 mg/L. Conclusions: CRP at admission could help diagnose infection in cirrhotic patients. Since the severity of liver disease seems to affect the CRP values, lower CRP levels might indicate infection. Clinical suspicion is necessary to avoid delay in diagnosis and initiate antibiotic treatment. PMID:29333070

    There is a need to improve the reproductive efficiency of carabaos to meet the increasing demand for draught power, meat and milk. Under village conditions carabaos appear to have a pregnancy rate of 17.7%; this could be attributed greatly to tethering management, which prevents their natural breeding activities. Moreover, about 32% of the breedable female carabaos are acyclic and only 3.5% are in oestrus at any one time. Carabaos which are either cycling or pregnant have a better body condition than those which are acyclic or non-pregnant. The plasma progesterone level was very low at the time of insemination (<0.5 ng/mL), but gradually increased to above 2.0 ng/mL during the first and second trimesters of pregnancy. Thus, it was possible to diagnose early pregnancy and to confirm oestrus. A positive correlation was observed between plasma and milk progesterone concentrations during the oestrous cycle (r=0.60) and pregnancy (r=0.50). Oestrus synchronization was found to be a useful tool in implementing the cross-breeding of Philippine carabaos with riverine buffaloes through artificial insemination; an average pregnancy rate of about 30% was obtained using frozen semen. The performance of cross-breds showed that the weights at birth were about 36.0 ± 0.9 kg for Phil-Ravi, 33.6 ± 0.9 kg for Phil-Murrah compared with 26.8 ± 0.9 kg for Philippine carabaos. The weights of the three genotypes at 12 months were: 157.0 ± 9.8 kg for Philippine carabaos, 215.4 ± 7.7 kg for Phil-Ravi and 199.8 ± 12.1 kg for Phil-Murrah. At 2 years of age, the carabaos weighed 217.3 ± 18.6 kg, Phil-Ravi 365 ± 23.4 kg and Phil-Murrah 366.3 ± 19.4 kg. The results of this study show that progesterone measurement and oestrus synchronization can be used effectively for cross-breeding carabaos with the frozen semen of river buffaloes.

    The study was undertaken to determine, from the patient's perspective, the comparative effectiveness of locally established financial protection mechanisms particularly for indigent and severely-ill hospitalized patients. Data was obtained from a survey conducted in 2010 in Philippine provinces which were part of the Health Systems Development Project and involved 449 patients from selected private and public hospitals. Direct medical expenses incurred during the confinement period, whether already paid for prior to or only billed upon discharge, were initially considered. Expenses were found to be generally larger for the more severely ill and lower for the poor. Hospital-provided discounts and social health insurance (PhilHealth) reimbursements were the financial protection mechanisms evaluated in this study. In average terms, only up to 46% of inpatient expenses were potentially covered by the combined financial support. Depending on the hospital type, 28-42% of submitted PhilHealth claims were invalidated. Multiple linear regression analysis was utilized to determine the relationship of the same set of patients' demographic characteristics, socioeconomic status, severity of illness, and hospital assignments with selected expense categories and financial protection measures. Pre-discharge expenditures were significantly higher in public hospitals. The very ill also faced significantly larger expenses, including those for final hospital charges. Hospital-derived discounts provided significantly more support for indigent as well as very sick patients. The amounts for verified PhilHealth claims were significantly greater for the moderately-ill and, incongruously, the financially better-off patients. Sponsored Program members, supposed indigents enjoying fully-subsidized PhilHealth enrollment, qualified for higher mean reimbursements. However, there was a weak correlation between such patients and those identified as poor by the hospital social service staff. Thus

    To determine 1) the cost of hospitalization, the 1-week postdischarge cost, the total cost, and the economic burden of community-acquired pneumonia among patients aged 19 years or older in the Philippines and 2) the difference between the estimated costs and the Philippine Health Insurance Corporation (PhilHealth) pneumonia case rate payments. The study involved two tertiary private hospitals in the Philippines. Using the societal perspective, both health care and non-health care costs were determined. A base-case analysis and sensitivity analyses were performed, and the economic burden of pneumonia was determined using PhilHealth claims. The estimated cost of hospitalization for community-acquired pneumonia-moderate risk (CAP-MR) ranged from Philippine peso (PHP) 36,153 to 113,633 (US $852-2678) and its 1-week postdischarge cost ranged from PHP1450 to 8800 (US $34-207). The cost of hospitalization for community-acquired pneumonia-high risk (CAP-HR) ranged from PHP104,544 to 249,695 (US $2464-5885) and PHP101,248 to 243, 495 (US $2386-5739) using invasive and noninvasive ventilation, respectively. The postdischarge cost for CAP-HR ranged from PHP1716 to 10,529 (US $40-248). If only health care cost was considered, the cost ranged from PHP24,403 to 89,433 for CAP-MR and PHP92,848 to 213,395 for CAP-HR. The present PhilHealth case rate payments are PHP15,000 (US $354) and PHP32,000 (US $754) for CAP-MR and CAP-HR, respectively. Based on the number of PhilHealth claims for 2012 and the estimated health care cost, the economic burden of pneumonia in 2012 was PHP8.48 billion for CAP-MR and PHP643.76 million for CAP-HR. The estimated health care cost of hospitalization is markedly higher than the PhilHealth case rate payments. As per the study results, the economic burden of pneumonia is, thus, significantly higher than PhilHealth estimates.

    This paper presents the power hardware in the loop (PHIL) validation of a feed forward DC voltage control scheme for the fault ride through (FTR) of voltage source converter (VSC) high voltage DC (HVDC) connected offshore wind power plants (WPPs). In the proposed FRT scheme, the WPP collector...... network AC voltage is actively controlled by considering both the DC voltage error and the AC current from the WPP AC collector system which ensures fast and robust FRT of the VSC HVDC connected offshore WPPs. The PHIL tests were carried out in order to verify the efficacy of the proposed feed forward DC...... voltage control scheme for enhancing the FRT capability of the VSC HVDC connected WPPs. The PHIL test results have demonstrated the proper control coordination between the offshore WPP and the WPP side VSC and the efficient FRT of the VSC HVDC connected WPPs....

    Eosinophils accumulate at the site of allergic inflammation and are critical effector cells in allergic diseases. Recent studies have also suggested a role for eosinophils in the resolution of inflammation. To determine the role of eosinophils in the resolution phase of the response to repeated allergen challenge. Eosinophil-deficient (PHIL) and wild-type (WT) littermates were sensitized and challenged to ovalbumin (OVA) 7 or 11 times. Airway inflammation, airway hyperresponsiveness (AHR) to inhaled methacholine, bronchoalveolar lavage (BAL) cytokine levels, and lung histology were monitored. Intracellular cytokine levels in BAL leukocytes were analyzed by flow cytometry. Groups of OVA-sensitized PHIL mice received bone marrow from WT or IL-10(-/-) donors 30 days before the OVA challenge. PHIL and WT mice developed similar levels of AHR and numbers of leukocytes and cytokine levels in BAL fluid after OVA sensitization and 7 airway challenges; no eosinophils were detected in the PHIL mice. Unlike WT mice, sensitized PHIL mice maintained AHR, lung inflammation, and increased levels of IL-4, IL-5, and IL-13 in BAL fluid after 11 challenges whereas IL-10 and TGF-β levels were decreased. Restoration of eosinophil numbers after injection of bone marrow from WT but not IL-10-deficient mice restored levels of IL-10 and TGF-β in BAL fluid as well as suppressed AHR and inflammation. Intracellular staining of BAL leukocytes revealed the capacity of eosinophils to produce IL-10. After repeated allergen challenge, eosinophils appeared not essential for the development of AHR and lung inflammation but contributed to the resolution of AHR and inflammation by producing IL-10.

    Abstract Sorafenib is the only Food and Drug Administration (FDA)-approved first-line therapy shown to have survival benefit for patients with advanced hepatocellular carcinoma (HCC). Patients with advanced HCC are often but not exclusively transferred from non-oncologists to oncologists to initiate systemic therapy. The objective of this study was to assess whether sorafenib prescribing by non-oncologists has any impact on utilization, adverse effects, cost or outcome. This was a retrospective cohort study utilizing data from patients prescribed sorafenib for HCC within Veterans Health Administration hospitals with 100% chart abstraction to confirm HCC diagnosis, identify prescribing provider specialty (oncology versus gastroenterology/hepatology), and obtain data required for cancer staging by the Barcelona Clinic Liver Cancer (BCLC) system. The primary outcome was overall survival from the time of sorafenib prescription. A total of 4903 patients who prescribed sorafenib for HCC were identified, for whom 340 patients (6.9%) were prescribed drug by a non-oncologist (Onc). BCLC Stage, age, Child–Turcotte–Pugh score, and comorbidity indices were similar between patients prescribed sorafenib by oncologists and non-oncologists. Oncologists more often discontinued sorafenib due to progression, whereas non-oncologists were more likely to continue sorafenib until death resulting in greater pill utilization and cost. Overall survival in both unadjusted and multivariable models showed no significant impact of prescriber type on survival (222 vs 217 days, P = .96), confirmed with propensity-matched subcohorts. Similar survival outcomes were observed for patients with HCC prescribed sorafenib by non-oncologists and oncologists, suggesting that non-oncologists with expertise in the management of HCC can safely and effectively administer sorafenib.

    Full Text Available ObjectiveTo investigate the risk factors for non-anastomotic biliary stricture (NABS following liver transplantation. MethodsA retrospective analysis was performed on 175 patients who underwent liver transplantation from January 2004 to December 2010 to analyze the risk factors for NABS, which included sex, age, primary disease, blood type, T-tube placement, acute rejection, biliary tract infection, cytomegalovirus infection, Child-Pugh score, cold ischemia time, warm ischemia time, duration of anhepatic phase, and mean hepatic artery blood flow within one week after operation. These patients were divided into early group, who underwent operation from January 2004 to December 2006, and late group, who underwent operation from January 2007 to December 2010; each group was further divided into two subgroups according to whether they developed NABS. The risk factors for NABS were determined by univariate and multivariate logistic regression analyses. ResultsThe univariate logistic regression analysis showed that the risk factors for NABS were biliary tract infection, T-tube placement, and acute rejection in the early group (P<0.05 and that acute rejection was the risk factor in the late group (P=0003. The multivariate logistic regression analysis showed that acute rejection was significantly associated with NABS in the early group (P=0.014. ConclusionThe risk factors for NABS following liver transplantation from January 2004 to December 2006; biliary tract infection and T-tube placement could be prevented by perioperative interventions, thus reducing the incidence of NABS. The incidence of acute rejection was reduced from January 2007 to December 2010, but it was still significantly associated with NABS.

    Ghrelin, leptin, and insulin concentrations are involved in the control of food intake and they seem to be associated with anorexia-cachexia in cirrhotic patients. The present study aimed to investigate the relationship between the nutritional status and fasting ghrelin, leptin and insulin concentrations in pediatric cirrhotic patients. Thirty-nine patients with cirrhosis and 39 healthy controls aged 0-15 years matched by sex and age were enrolled. Severity of liver disease was assessed by Child-Pugh classification, and Pediatric for End Stage Liver Disease (PELD) or Model for End-stage Liver Disease (MELD) scores. Blood samples were collected from patients and controls to assay total ghrelin, acyl ghrelin, leptin and insulin by using a commercial ELISA kit. Anthropometry parameters used were standard deviation score of height-for-age and triceps skinfold thickness-for-age ratio. A multiple linear regression analysis was used to determine the correlation between dependent and independent variables. Acyl ghrelin was significantly lower in cirrhotic patients than in controls [142 (93-278) pg/mL vs 275 (208-481) pg/mL, P=0.001]. After multiple linear regression analysis, total ghrelin and acyl ghrelin showed an inverse correlation with age; acyl ghrelin was associated with the severity of cirrhosis and des-acyl ghrelin with PELD or MELD scores ≥15. Leptin was positively correlated with gender and anthropometric parameters. Insulin was not associated with any variable. Low acyl ghrelin and high des-acyl ghrelin concentrations were associated with cirrhosis severity, whereas low leptin concentration was associated with undernourishment in children and adolescents with cirrhosis.

    We evaluated clinical outcomes and prognostic factors associated with survival after balloon-occluded retrograde transvenous obliteration (B-RTO) of gastric varices in patients with portal hypertension. Of 50 patients with gastric varices who underwent B-RTO, 46 (94.0%) patients in whom B-RTO was technically successful were reviewed retrospectively. Gastric and esophageal varices after B-RTO were evaluated by contrast-enhanced computer tomography and endoscopy, respectively. Liver function parameters and Child-Pugh scores were estimated before and at 1 year after B-RTO. The cumulative survival rate was calculated, and univariate and multivariate analyses were used to assess the prognostic factors. No major complications occurred in any of the patients following B-RTO and no recurrence or bleeding of gastric varices was noted. Of the 42 patients who were followed up for the progression of esophageal varices, 13 (31.0%) had worsened varices and of these, 6 (14.3%) showed bleeding. Prothrombin activity had significantly improved at 1 year after B-RTO, although there were no changes in other liver function parameters. The overall cumulative survival rates at 1, 3, and 5 years after B-RTO were 91.6%, 70.9%, and 53.6%, respectively. Multivariate analysis identified the occurrence of advanced hepatocellular carcinoma (HCC) during the observation period as a prognostic factor for survival (hazard ratio=4.1497, 95% CI=1.32314-13.0319, P=0.0148). B-RTO of gastric varices is an effective treatment ensuring lower recurrence and bleeding rates; however, these patients require careful observation for progression of esophageal varices. The management of HCC is crucial for achieving long-term survival after B-RTO. (author)

    Periodic endoscopy for esophageal varices (EVs) and prophylactic treatment of high-risk EVs, i.e., medium/large EVs, small EVs with the red-color sign or decompensation, are recommended in cirrhotic patients. We assessed the cumulative risks for future EV bleeding using the following simple P2/MS index: (platelet count)2/[monocyte fraction (%) × segmented neutrophil fraction (%)]. We enrolled 475 consecutive B-viral cirrhosis patients for 4 years, none of whom experienced EV bleeding. All underwent laboratory work-ups, endoscopy and ultrasonography. Those with EV bleeding took a nonselective β-blocker as prophylaxis. The major endpoint was the first occurrence of EV bleeding, analyzed using the Kaplan-Meier and Cox regression methods. Among patients with EV bleeding (n = 131), 25 experienced their first EV bleeding during follow-up. To differentiate the risk for EV bleeding, we divided them into two subgroups according to their P2/MS value (subgroup 1: P2/MS ≥9 and subgroup 2: P2/MS P2/MS (p = 0.040) remained a significant predictor for EV bleeding along with large varix size (p = 0.015), red-color sign (p = 0.041) and Child-Pugh classification B/C (p = 0.001). In subgroup 1, the risk for EV bleeding was similar to that of patients with low-risk EVs (p = 0.164). The P2/MS is a reliable predictor for the risk of EV bleeding among patients with EV bleeding. According to risk stratification, different prophylactic treatments should be considered for the subgroup with a P2/MS <9. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available Orthotopic liver transplantation (OLT is the only treatment for many patients with end-stage chronic liver diseases. In patients with complete vena cava inferior (VCI cross-clamping veno-venous bypass (VVB is either used or not depending on the indications. The case management of the patient with complete VCI cross-clamping depends on the initial state of the recipient and the transplant team’s opinion.Aim. To compare the perioperative period of OLT depending on the method to conduct the main stage of the surgery: with the use of veno-venous bypass and without it with complete VCI cross-clamping.Materials and methods. In Group 1 (n = 20, OLT was performed without VVB with complete VCI cross-clamping; in Group 2 (n = 26, the surgery was conducted with veno-venous bypass. Patients in both groups were similar in age (46.15 ± 10.22 and 47.3 ± 9.29, respectively, in severity of the disease: Child-Pugh (10.15 ± 1.42 and 10.19 ± 2.45, MELD 16.47 ± 4.41 and 15.8 ± 4.95.Results. We determined and evaluated hemodynamic parameters, oxygen transport, the quantitative and qualitative infusion composition, urine output, characteristics of the postoperative period.Conclusion. Our data show that changes in hemodynamic and oxygen transport are associated with reperfusion syndrome and do not depend on the method of transplantation. At the same time, it reduces the blood loss, time of surgery, and the duration of postoperative mechanical ventilation and stay in the ICU after liver transplantation in patients without veno-venous bypass.

    PurposeLocoregional therapy for hepatocellular carcinoma (HCC) can be challenging in patients with a transjugular intrahepatic portosystemic shunt (TIPS). This study compares safety and imaging response of ablation, chemoembolization, radioembolization, and supportive care in patients with both TIPS and HCC.MethodsThis retrospective study included 48 patients who had both a TIPS and a diagnosis of HCC. Twenty-nine of 48 (60 %) underwent treatment for HCC, and 19/48 (40 %) received best supportive care (i.e., symptomatic management only). While etiology of cirrhosis and indication for TIPS were similar between the two groups, treated patients had better baseline liver function (34 vs. 67 % Child-Pugh class C). Tumor characteristics were similar between the two groups. A total of 39 ablations, 17 chemoembolizations, and 10 yttrium-90 radioembolizations were performed on 29 patients.ResultsAblation procedures resulted in low rates of hepatotoxicity and clinical toxicity. Post-embolization/ablation syndrome occurred more frequently in patients undergoing chemoembolization than ablation (47 vs. 15 %). Significant hepatic dysfunction occurred more frequently in the chemoembolization group than the ablation group. Follow-up imaging response showed objective response in 100 % of ablation procedures, 67 % of radioembolization procedures, and 50 % of chemoembolization procedures (p = 0.001). When censored for OLT, patients undergoing treatment survived longer than patients receiving supportive care (2273 v. 439 days, p = 0.001).ConclusionsAblation appears to be safe and efficacious for HCC in patients with TIPS. Catheter-based approaches are associated with potential increased toxicity in this patient population. Chemoembolization appears to be associated with increased toxicity compared to radioembolization.

    AIM: To identify prognostic factors for long-term outcome for patients with hepatocellular carcinoma (HCC) after percutaneous microwave or radiofrequency ablation. MATERIALS AND METHODS: In total, 137 consecutive patients with HCC underwent microwave or radiofrequency ablation with curative intent; 16 possible prognostic factors were evaluated for their association with overall survival (OS) and disease-free survival (DFS) using univariate and multivariate analysis. RESULTS: The median OS and DFS were 27.0 months and 8.2 months, respectively. OS rates for all patients at 1, 2, 3, 4 and 5 years were 73.9%, 52.1%, 42.8%, 26.2% and 20.1%, respectively. DFS rates at 1, 2, 3 and 4 years were 38.1%, 21.9%, 18.8%, and 14.1%, respectively. Pretreatment serum alpha-fetoprotein (AFP) >200 ng/ml, pretreatment serum albumin {<=}35 g/dl, liver function Child's class C and incomplete ablation were found to be significant predictors for OS by univariate analysis. Using multivariate analysis, incomplete ablation was identified to be the most significant independent predictor for OS. Other independent predictors for OS were serum albumin level, serum AFP level and Child-Pugh classification. Recurrence after hepatectomy and prothrombin time >14 s were identified to be significant predictors for DFS by univariate analysis, and the former was the only independent predictor for DFS by multivariate analysis. CONCLUSION: Prognosis for patients with HCC after thermal ablation with curative intent was determined by treatment response to ablation, pretreatment serum AFP, and liver function reserve. Tumour response to treatment was the most predictive factor for long-term survival and was related to tumour size, thus careful selection of patients for ablation therapy is recommended.

    Currently, the only standard systemic treatment for advanced hepatocellular carcinoma is sorafenib monotherapy. The study was conducted to assess the efficacy and safety of the novel combination of sorafenib and gemcitabine in the treatment of advanced hepatocellular carcinoma. Between March 2008 and October 2010, patients with advanced pathologically proven hepatocellular carcinoma who had not received previous systemic therapy and had Child-Pugh liver function class A or B received sorafenib plus gemcitabine. Treatment included 4-week cycle of gemcitabine (1000 mg/m(2) days 1, 8, 15) to the maximum of six cycles together with sorafenib (400 mg twice daily). Patient continued sorafenib until disease progression or withdrawal from other reasons. The primary end point is progression-free survival. Forty-five patients were enrolled in this study. The median progression-free survival was 3.7 months (95% CI 3.5-3.8). The overall response rate was 4% with no complete responses and the disease control rate was 66%. The median overall survival (OS) was 11.6 months (95% CI 7.4-15.9). The median time to progression was 3.6 months (95% CI 3.4-3.7). The most frequently reported grade 3/4 treatment-related adverse events included thrombocytopenia 33%, neutropenia 16% and hand-foot skin reaction 13%. The study regimen was well tolerated. The combination of sorafenib and gemcitabine in advanced hepatocellular carcinoma is generally well tolerated and has modest clinical efficacy. The median OS is up to 1 year. However, well-designed randomized controlled trials with a sorafenib alone comparator arm are needed to confirm this finding. © 2014 Wiley Publishing Asia Pty Ltd.

    Patients with advanced hepatocellular carcinoma (HCC) with jaundice have an extremely poor prognosis. Although biliary drainage can resolve obstructive jaundice, signs of obstruction may not be evident. This study evaluated the role of endoscopic biliary drainage in patients with advanced HCC and obstructive jaundice. From 2010 to 2015, 74 patients underwent endoscopic biliary drainage for obstructive jaundice due to advanced HCC. Jaundice resolution was defined as complete response and total bilirubin concentration below 3 mg/dl. The technical success rate in the 74 patients was 92.1% (70/76). Of the 70 patients who underwent successful biliary drainage, 48 (68.6%) and 22 (31.4%) were Child-Pugh classes B and C, respectively, and 10 (14.3%) and 60 (85.7%) were BCLC stages B and C, respectively. Intrahepatic bile duct (IHD) dilatation was observed in 35 patients (50%). After drainage, the complete response rate was 35.7% (25/70). The mean time to resolution was 17.4 ±8.5 days. However, jaundice was re-aggravated in 74.3% (15/25) after a mean 103.5 ±96.4 days. Multivariate analysis showed that the absence of ascites, presence of IHD dilatation, normal range of prothrombin time, and lower MELD score were significantly associated with complete response. The overall survival rate was 15.7% (11/70) and the median survival time is 28 days (95% confidence interval 2.6-563 days). Complete response and HCC treatment after drainage were significantly associated with survival. Effective endoscopic biliary drainage is an important palliative treatment in patients with advanced HCC and obstructive jaundice, especially those with IHD dilatation and preserved liver function, as determined by ascites, prothrombin time, and MELD score.

    Malnutrition and jaundice are independent prognostic factors in cirrhosis. To assess the impact of enteral nutrition on the survival of alcoholic cirrhotic patients with jaundice but without acute alcoholic hepatitis. The study was a multicentre prospective randomised controlled trial comparing effects of enteral nutrition vs. a symptomatic support in patients with alcoholic cirrhosis and jaundice (bilirubin ≥51 µmol/L) but without severe acute alcoholic hepatitis. A total of 99 patients were randomised to receive either the conventional symptomatic treatment (55 patients) or the symptomatic support associated with 35 kcal/Kg/day of enteral nutrition during 4 weeks followed by an oral nutritional support during 2 months (44 patients). Randomisation was stratified on nutritional status. One-year survival curves were compared using the Kaplan-Meier method and Logrank test. Populations in both arms were similar. One-year survival was similar in the overall population (27/44 patients (61.4%) in the enteral nutrition arm vs. 36/55 (65.5%) in the control arm; Logrank P = 0.60) and in the subgroup suffering from malnutrition [18/29 patients (62.1%) in the enteral nutrition arm vs. 20/32 (62.5%) in the control arm; Logrank P = 0.99]. There was no statistical difference for bilirubin, prothrombin rate, Child-Pugh score, albumin or nutritional assessment. Complications during treatment (bleeding, encephalopathy, infection) occurred in 23% of patients in the enteral nutrition group (10/44) vs. 16% (9/55) of the control patients (P = 0.59). Enteral nutrition does not improve the survival and hepatic or nutritional parameters of cirrhotic patients with jaundice. © 2012 Blackwell Publishing Ltd.

    Prediction of the outcome of sorafenib therapy using biomarkers is an unmet clinical need in patients with advanced hepatocellular carcinoma (HCC). The aim was to develop and validate a biomarker-based model for predicting sorafenib response and overall survival (OS). This prospective cohort study included 124 consecutive HCC patients (44 with disease control, 80 with progression) with Child-Pugh class A liver function, who received sorafenib. Potential serum biomarkers (namely, hepatocyte growth factor [HGF], fibroblast growth factor [FGF], vascular endothelial growth factor receptor-1, CD117, and angiopoietin-2) were tested. After identifying independent predictors of tumor response, a risk scoring system for predicting OS was developed and 3-fold internal validation was conducted. A risk scoring system was developed with six covariates: etiology, platelet count, Barcelona Clinic Liver Cancer stage, protein induced by vitamin K absence-II, HGF, and FGF. When patients were stratified into low-risk (score ≤ 5), intermediate-risk (score 6), and high-risk (score ≥ 7) groups, the model provided good discriminant functions on tumor response (concordance [c]-index, 0.884) and 12-month survival (area under the curve [AUC], 0.825). The median OS was 19.0, 11.2, and 6.1 months in the low-, intermediate-, and high-risk group, respectively (P functions on tumor response (c-index, 0.825) and 12-month survival (AUC, 0.803), and good calibration functions (all P > 0.05 between expected and observed values). This new model including serum FGF and HGF showed good performance in predicting the response to sorafenib and survival in patients with advanced HCC.

    To describe our 20-year experience with transjugular intrahepatic portosystemic shunt (TIPSS) procedures for children with resistant portal hypertension (PHTN). Retrospective review of all children that had a TIPSS performed at Birmingham Children's Hospital from 1 January 1995 - 1 January 2015. 40 children underwent 42 attempted TIPSS for resistant PHTN with recurrent variceal bleeding (n = 35), refractory ascites (n = 4), and hypersplenism (n = 1). Median age at operation was 12 years (range, 7 months - 17 years). Thirty-four procedures were elective and 8 were emergency cases.TIPSS was established in 33 cases (79%). Median portal venous pressure reduction was 10mmHg. Variceal bleeding ceased in 27 (96%) and ascites improved in all. Clinical improvement following TIPSS enabled 7 children to be bridged to transplantation and 7 others to become suitable for transplantation. The 1-year and 5-year survival with TIPSS was 57% and 35%, respectively. Child-Pugh score C was an independent risk factor for adverse outcome (LR = 8.0; 95% CI 2.7 - 23.5; P = 0.001).There were 6 major complications: hepatic artery thrombosis and infarction (n = 1), hepatic artery pseudoaneurysm (n = 1), bile leak (n = 1), and hepatic encephalopathy (n = 3). Encephalopathy was resistant to medical treatment in 2 cases, necessitating staged closure in one.Ten patients (30%) required intervention to maintain TIPSS patency. The 1-year and 5-year freedom from reintervention was 71% and 55%, respectively. A TIPSS is highly successful in controlling symptoms in children with resistant PHTN and facilitating liver transplantation. However, it is technically demanding and not without risk. Patients must be appropriately selected and counselled.

    Full Text Available Purpose: To analyze the distribution of functional liver volume (FLV in the margin volume (MV surrounding hepatocellular carcinoma (HCC with portal vein tumor thrombus (PVTT before radiation therapy (RT and to verify the safety of single photon emission computed tomography-based three-dimensional conformal radiotherapy (SPECT-B3DCRT by exploring the relation of FLV in MV to radiation-induced liver disease (RILD. Methods and Materials: Clinical target volume (CTV included main tumor and PVTT, and planning target volume (PTV included CTV with a 10 mm margin. MV was defined as PTV–CTV. FLV ratio in MV was calculated as FLV in MV/MV × 100 (%. The two high-dose beams were planned to irradiate FLV as little as possible. Fifty-seven cases of HCC (26/57, 46%; Child–Pugh grade B with PVTT underwent SPECT-B3DCRT which targeted the CTV to a total dose of 45 Gy/18 fractions. The destructive ratio was defined as radiation induced dysfunctional volume/FLV × 100 (%. Results: We observed a significant negative correlation between FLV ratio in MV and CTV (p < 0.001. Three cases with CTVs of 287, 587 and 1184 cm3 experienced transient RILD. The FLV ratio in MV was highest in patients with RILD: nine patients with CTV of 200–300 cm3, three with CTV of 500–600 cm3, and two with CTV of 1100–1200 cm3. The destructive ratio yielded a mean value of 24.2 ± 1.5%. Conclusions: Radiation planning that takes into account the distribution of FLV appears to result in the least possible RILD.

    Full Text Available Bleeding from gastro-esophageal varices is the most serious and life-threatening complication of cirrhosis. Endoscopic surveillance of esophageal varices in cirrhotic patients is expensive and uncomfortable for the patients. Therefore, there is a particular need for non-invasive predictors for esophageal varices. The aim of the present study was to evaluate association of esophageal varices and Lok Score as non-invasive parameter in liver cirrhosis patients. This is a cross-sectional study of patients admitted at the Adam Malik hospital Medan between September to December 2014 with a diagnosis of cirrhosis based on clinical, biochemical examination, ultrasound, and gastroscopy. Lok Score was calculated for all patients, tabulated and analyzed. Among 76 patients with esophageal varices, 55.3% was due to hepatitis B virus (HBV. The majority of patients were Child C with only 13,2% being Child Pugh class A. Majority of the population had F2 esophageal varices (42.1%, F1 (32.9%, and F3 (25%. There is significance difference between Lok Score and grading of esophageal varices, in which Lok Score is higher in large esophageal varices compared with small esophageal varises (0.92 ± 0.14 vs. 0.70 ± 0.29; p = 0.001. Lok Score with cut-off point of > 0.9141 was highly predictive in the diagnosis large esophageal varices with a sensitivity of 74.5%, specificity of 72%, positive predictive value of 84%, negative predictive value 58%, and accuracy was 73.7%. Lok Score was significantly associated with esophageal varices. Lok Score is a good non-invasive predictor of large esophageal varices in cirrhotic patients.
