2Non-invasive splenic parameters of portal hypertension:Assessment and utility显示文摘BACKGROUND Portal hypertension is a major complication of cirrhosis that is associated with significant morbidity and mortality.The present gold-standard method to risk stratify and observe cirrhosis patients with portal hypertension is hepatic venous pressure gradient measurement or esophagogastroduodenoscopy.However,these methods are invasive,carry a risk of complications and are associated with significant patient discomfort.Therefore,non-invasive splenic parameters are of clinical interest as potential useful markers in determining the presence of portal hypertension.However,diagnostic accuracy and reproducibility remains unvalidated.AIM To assess the diagnostic accuracy of spleen stiffness,area and diameter in predicting the presence of portal hypertension.METHODS Of 50 patients with varying liver disease pathologies were prospectively recruited from the St.Mary’s Hospital Liver Unit in London;25 with evidence of portal hypertension and 25 with no evidence of portal hypertension.Liver stiffness,spleen stiffness,spleen diameter and spleen area were measured using the Philips Affiniti 70 elastography point quantification point shear wave elastography system.The aspartate aminotransferase-to-platelet-ratio-index(APRI)score was also calculated.Performance measures,univariate and multivariate logistic regression were used to evaluate demographic,clinical and elastography variables.Interclass correlation coefficient was used to determine the reproducibility of splenic area and diameter.RESULTS On univariate and individual performance,platelet count[area under the receiver operating characteristic(AUROC)0.846,P value<0.001],spleen area(AUROC 0.828,P value=0.002)and APRI score(AUROC 0.827,P value<0.001)were the most accurate variables in identifying the presence of portal hypertension.On multivariate logistic regression models constructed,the combination of spleen area greater than 57.90 cm2 and platelet count less than 126×10^9 had 63.2%sensitivity and 100%specificity,100%positive predictive value and 100%negative predictive value.An alternative combination of spleen stiffness greater than 29.99 kPa and platelet count less than 126×10^9 had 88%sensitivity,75%specificity,78.6%positive predictive value and 85.7%negative predictive value.An interclass correlation coefficient value of 0.98(95%CI:0.94-0.99,P value<0.001)and 0.96(95%CI:0.91-0.99,P value<0.001)were determined for inter-operator variability for spleen area and diameter respectively.CONCLUSION Spleen area,spleen stiffness and platelet count may be useful markers to assess the presence of portal hypertension in patients of various etiologies.Ayesha Karim Ahmad Sebastiana Atzori James Maurice Simon D Taylor-Robinson Adrian KP Lim 2020World Journal of Hepatology2020,12,11:2

4Changes in foliar carbon isotope composition and seasonal stomatal conductance reveal adaptive traits in Mediterranean coppices affected by drought显示文摘We estimated water-use efficiency and potential photosynthetic assimilation of Holm oak(Quercus ilex L.) on slopes of NW and SW aspects in a replicated field test examining the effects of intensifying drought in two Mediterranean coppice forests. We used standard techniques for quantifying gas exchange and carbon isotopes in leaves and analyzed total chlorophyll, carotenoids and nitrogen in leaves collected from Mediterranean forests managed under the coppice system. We postulated that responses to drought of coppiced trees would lead to differential responses in physiological traits and that these traits could be used by foresters to adapt to predicted warming and drying in the Mediterranean area. We observed physiological responses of the coppiced trees that suggested acclimation in photosynthetic potential and water-use efficiency:(1) a significant reduction in stomatal conductance(p<0.01) wasrecorded as the drought increased at the SW site;(2) foliar δ13C increased as drought increased at the SW site(p<0.01);(3) variations in levels of carotenoids and foliar nitrogen, and differences in foliar morphology were recorded, and were tentatively attributed to variation in photosynthetic assimilation between sites. These findings increase knowledge of the capacity for acclimation of managed forests in the Mediterranean region of Europe.Giovanni Di Matteo Luigi Perini Paolo Atzori Paolo De Angelis Tiziano Mei Giada Bertini Gianfranco Fabbio Giuseppe Scarascia Mugnozza 2014Journal of Forestry Research2014,25,4:2
