Use of liver stiffness measurement for liver resection surgery: correlation with indocyanine green clearance testing and post-operative outcome

Background:Liver stiffness measurement (LSM) using transient elastography has recently become available for the assessment of liver fibrosis. Whether LSM can predict the functional liver reserve in patients undergoing liver resection is not certain.Aim:To correlate liver stiffness measurement (LSM) with indocyanine green (ICG) clearance test and liver biochemistry, and to determine its usefulness in predicting postoperative outcomes in patients undergoing liver resection.Patients and Methods:Transient elastography and ICG clearance test were performed pre-operatively in 44 patients with hepatocellular carcinoma. The LSM and ICG retention rate at 15 minutes (R15) were correlated with pre-operative factors and post-operative outcomes.Results:There was significant correlation between ICG R15 and LSM. In patients with LSM ≥11 kPa vs <11 kPa, there was significantly higher ICG R15 (17.1% vs 10.0% respectively, p = 0.025). For patients with ICG R15≥10% compared to those <10%, there was significantly higher LSM (12.0 vs 7.6 kPa respectively, p = 0.015). Twenty-eight patients proceeded to resection. There was a significant correlation between LSM and the peak INR after liver resection (r = 0.426, p = 0.024). There was a significant correlation between ICG R15 and the post-operative peak AST level (r = -0.414, p = 0.029) and peak ALT level (r = -0.568, p = 0.002). The operative time was a significant independent factor associated with post-operative complications and peak INR.Conclusion:LSM correlated well with ICG R15 in patients undergoing liver resection, and predicted early post-operative complications. Addition of LSM to ICG R15 testing may provide better prognostic information for patients undergoing resection. © 2013 Fung et al.published_or_final_versio

Volumetric analysis and indocyanine green retention rate at 15 min as predictors of post‐hepatectomy liver failure

AbstractObjectivesThe actual future liver remnant (aFLR) is calculated as the ratio of remnant liver volume (RLV) to total functional liver volume (TFLV). The standardized future liver remnant (sFLR) is calculated as the ratio of RLV to standard liver volume (SLV). The aims of this study were to compare the aFLR with the sFLR and to determine criteria for safe hepatectomy using computed tomography volumetry and indocyanine green retention rate at 15 min (ICG R15).MethodsMedical records and volumetric measurements were obtained retrospectively for 81 patients who underwent right hemi‐hepatectomy for malignant hepatic tumours from January 2010 to November 2013. The sFLR was compared with the aFLR, and a ratio of sFLR to ICG R15 as a predictor of postoperative hepatic function was established.ResultsIn patients without cirrhosis, the sFLR showed a stronger correlation with the total serum bilirubin level than the aFLR (R2 = 0.499 versus R2 = 0.239). Post‐hepatectomy liver failure developed only in the group with an sFLR of <25%, regardless of ICG R15. In patients with cirrhosis, the aFLR and sFLR had no correlation with postoperative total serum bilirubin. An sFLR : ICG R15 ratio of >1.9 showed 66.7% sensitivity and 100% specificity.ConclusionsRegardless of ICG R15, an sFLR of ≥25% in patients without cirrhosis, and an sFLR of ≥25% with an sFLR : ICG R15 ratio of >1.9 in patients with cirrhosis indicate acceptable levels of safety in major hepatectomy

Pengaruh Ekuitas Merek Terhadap Proses Keputusan Pembelian Konsumen Motor Yamaha R15 Di Palembang

This study was conducted to determine the influence of brand equity on consumer purchasing decisions motorcycle yamaha R15 in Palembang. This type of research is a kind of field study research through surveys. The sample used in this study is that consumers who have purchased a motor yamaha R15 100 respondents and the sampling technique used was purposive sampling technique. Data analysis techniques used are validity and reliability, classic assumption test, multiple linear regression analysis and hypothesis testing (coefficient of determination R2, F test, t test). Results from the study showed independent variables (X) are able to explain 57.2% of purchase decisions yamaha motor R15 and the remaining 42.8% is explained by other variables not included in this study. Partial assay results showed a positive brand association and significant impact, while brand awareness, brand loyalty, but significant negative effect, whereas the perception of quality and no significant negative effect on consumer purchasing decisions Yamaha motorcycle R15

Essai préliminaire de production d’oeufs des poules pondeuses (ISA Warren) enrichis en acides gras polyinsaturés oméga 3 avec les graines de Euphorbia heterophylla L.

 En Afrique, la notion de qualité nutritionnelle des oeufs de poules pondeuses semble être  abstraite. Afin d’y remédier, cette étude vise à déterminer l'impact d'un régime supplémenté en graines de Euphorbia heterophylla sur la qualité nutritionnelle d'oeufs de poules pondeuses. A cet effet, vingt-quatre poules (ISA Warren) de 1,4 kg ont reçu durant 28 jours soit un régime contrôle (RC) (100% d'aliment commercial), soit un régime expérimental (R15) (80% de RC, 5% de complément minéral vitaminé et 15% de graines de Euphorbia heterophylla). Les dosages effectués ont montré que le régime R15 a conduit à une baisse significative des proportions d’acides gras saturés, monoinsaturés, polyinsaturés n-6 et a induit à une augmentation significative de la proportion en acides gras polyinsaturés n-3. Les proportions des acides gras C18:3 n-3, C20:5 n-3, C22:5 n-3 et C22:5 n-3 des jaunes des oeufs issus de R15 ont été multipliées respectivement par 31, 10, 4 et 3. Une réduction significative de 18% du taux de cholestérol total a été observée avec le régime expérimental R15. La consommation de ce type d'oeuf permettrait d'améliorer la prévention des maladies cardiovasculaires, principales causes de mortalité dans les pays africains à revenu faible ou intermédiaire.© 2015 International Formulae Group.

To remedy it, this  study aims to determining the effect of a diet supplemented with seeds of Euphorbia heterophylla on the nutritional quality of layers’ eggs. For this purpose, twenty-four hens (ISA Warren) 1,4 kg for 28 days received either a control diet (RC) (100% food marketed) or an experimental diet (R15) (80% RC, 5% vitamin and mineral supplement 15% seeds of Euphorbia heterophylla). The analysis showed that R15 diet has significantly led to adecline in proportions saturated fatty acids, monounsaturated fatty acids, omega-6 PUFA and induced an significantly increase of the proportion of n-3 PUFA. The proportions of fatty acids C18:3 n-3, C20:5 n-3, C22:5 n-3 and C22:5 n-3 of yellow eggs from R15 have increased respectively by 31, 10, 4 and 3. A significantly reduction of 18% to cholesterol the egg yolk was observed with the experimental diet R15. The consumption of this type of egg will allow improve prevention of cardiovascular disease, leading cause of death in low- and middle-income.© 2015 International Formulae Group.

Spatial Variability of Tourism Demand and Differences in Economic Impact in a Rural Economic Development Context

Statistically predicted future tourism demand is used to conduct an economic impact analysis in twelve tourism zones in the state of Arkansas. The analysis reveals spatial variability in employment, and output growth that will continue into the future. Tourism has the potential as an economic growth engine for the state, especially in economically disadvantaged regions with long-term benefits.Tourism Demand, Economic Impact Analysis, Rural Development, Community/Rural/Urban Development, Resource /Energy Economics and Policy, R15, R58,
