| 1 | Haplotype of prostaglandin synthase 2/cyclooxygenase 2 is involved in the susceptibility to inflammatory bowel disease显示文摘AIM: Prostaglandin G/H synthase 2 (PTGS2 or COX2) is one of the key factors in the cellular response to inflammation.PTGS2 is expressed in the affected intestinal segments of patients with inflammatory bowel diseases (IBD). In IBD patients, non-steroidal anti-inflammatory drugs, which have been shown to reduce both the production and activity of PTGS2, may activate IBD and aggravate the symptoms.We aimed at examining genetic variants of PTGS2 that may be risk factors for IBD.METHODS: We genotyped 291 individuals diagnosed with IBD and 367 controls from the Dutch population for the five most frequent polymorphisms of the PTGS2 gene.Clinical data were collected on all patients. DNA was extracted via normal laboratory methods. Genotyping was carried out using multiplex PCR followed by the Invader Assay and the 5' exonuclease assay (TaqMan). New polymorphism screening was performed by pre-screening with denaturing high-performance liquid chromatography,followed by fluorescent sequencing.RESULTS: Allele 5209G was weakly associated with Crohn's disease (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.03-2.57), and allele 8473T with ulcerative colitis (OR 1.50, 95%CI 1.00-2.27). The haplotype including both alleles showed a strong association with IBD (OR 13.15, 95%CI 3.17-116.15). This haplotype, while rare (-0.3%) in the general population, is found more frequently in patients (3.5%).CONCLUSION: Our data suggest that this haplotype of PTGS2 contributes to the susceptibility of IBD. | David G Cox J Bart A Crusius Petra HM Peeters H Bas Bueno-de-Mesquita A Salvador Pe(n|~)a Federico Canzian | 2005 | World Journal of Gastroenterology2005，11，38： | 10 |
| 2 | Patterns of cancer recurrence in localized resected hepatocellular carcinoma显示文摘BACKGROUND:Tumor resection in non-metastatic hepatocellular carcinoma(HCC)patients with adequate liver reserve offers a potential cure,but has a high 5-year recurrence rate.We analyzed the patterns of cancer relapse after partial hepatectomy to guide post-operative management.METHODS:A total of 144 HCC patients(1996-2011)after partial hepatectomy were reviewed.Statistical correlations were determined using univariate and partition analyses.RESULTS:A median follow-up of 20 months showed recurrence in 71(49%)patients,and the median time to recurrence was 11.9 months.Vascular invasion(P<0.01)and number of lesions(P<0.01)predicted for recurrence.Histologic grade was not correlated with recurrence.Twenty-two(31%)patients developed both surgical margin(SM)and concurrent intrahepatic recurrences,and 28(40%)had non-SM intrahepatic recurrences with no other signs of recurrence.On partition analysis,the risk of marginal recurrence in patients with SM<1 mm and SM≥1 mm was 35%and 13.5%respectively.Approximately 57%of patients with intrahepatic recurrence had recurrence≤2.5 cm from SM.CONCLUSIONS:Intrahepatic recurrence after partial hepatectomy is common and is significantly associated with vascular invasion and tumor stage.About 57%of patients with intrahepatic relapse had a recurrence close(≤2.5 cm)to the SM.Additionally,patients with SM<1 mm have a higher recurrence rate and may benefit from adjuvant local therapy. | Aryavarta MS Kumar Elisha T Fredman Christopher Coppa Galal El-Gazzaz Federico N Aucejo May Abdel-Wahab | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，3： | 7 |
| 3 | Liver transplantation in patients with incidental hepatocellular carcinoma/cholangiocarcinoma and intrahepatic cholangiocarcinoma: a single-center experience显示文摘BACKGROUND: Reports of liver transplantation(LT) in patients with mixed hepatocellular carcinoma/cholangiocarcinoma(HCC/CC) and intrahepatic cholangiocarcinoma(ICC) are modest and have been mostly retrospective after pathological categorization in the setting of presumed HCC. Some studies suggest that patients undergoing LT with small and unifocal ICC or mixed HCC/CC can achieve about 40%-60% 5-year post-transplant survival. The study aimed to report our experience in patients undergoing LT with explant pathology revealing HCC/CC and ICC.METHODS: From a prospectively maintained database, we performed cohort analysis. We identified 13 patients who underwent LT with explant pathology revealing HCC/CC or ICC. RESULTS: The observed recurrence rate post-LT was 31%(4/13) and overall survival was 85%, 51%, and 51% at 1, 3 and 5 years, respectively. Disease-free survival was 68%, 51%, and 41% at 1, 3 and 5 years, respectively. In our cohort, four patients would have qualified for exception points based on updated HCC Organ Procurement and Transplantation Network imaging guidelines. CONCLUSIONS: Lesions which lack complete imaging characteristics of HCC may warrant pre-LT biopsy to fully elucidate their pathology. Identified patients with early HCC/CC or ICC may benefit from LT if unresectable. Additionally, incorporating adjunctive perioperative therapies such as in the case of patients undergoing LT with hilar cholangiocarcinoma may improve outcomes but this warrants further investigation. | Mohammed Elshamy Naftali Presser Abdulrahman Y Hammad Daniel J Firl Christopher Coppa John Fung Federico N Aucejo | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，3： | 6 |

| 5 | Fatty liver disease,an emerging etiology of hepatocellular carcinoma in Argentina显示文摘AIM To investigate any changing trends in the etiologies of hepatocellular carcinoma(HCC) in Argentina during the last years. METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications. | Federico Pinero Josefina Pages Sebastián Marciano Nora Fernández Jorge Silva Margarita Anders Alina Zerega Ezequiel Ridruejo Beatriz Ameigeiras Claudia D’Amico Luis Gaite Carla Bermúdez Manuel Cobos Carlos Rosales Gustavo Romero Lucas McCormack Virginia Reggiardo Luis Colombato Adrián Gadano Marcelo Silva | 2018 | World Journal of Hepatology2018，10，1： | 4 |
| 6 | Intermediate-advanced hepatocellular carcinoma in Argentina:Treatment and survival analysis显示文摘BACKGROUND Hepatocellular carcinoma(HCC) represents the sixteenth most frequent cancer in Argentina. The rise of new therapeutic modalities in intermediate-advanced HCC opens up a new paradigm for the treatment of HCC.AIM To describe real-life treatments performed in patients with intermediateadvanced HCC before the approval of new systemic options.METHODS This longitudinal observational cohort study was conducted between 2009 and2016 in 14 different regional hospitals from Argentina. Included subjects had intermediate-advanced Barcelona Clinic Liver Cancer(BCLC) HCC stages(BCLC B to D). Primary end point analyzed was survival, which was assessed for each BCLC stage from the date of treatment until last patient follow-up or death.Kaplan Meier survival curves and Cox regression analysis were performed, with hazard ratios(HR) calculations and 95% confidence intervals(95%CI).RESULTS From 327 HCC patients, 41% were BCLC stage B, 20% stage C and 39% stage D.Corresponding median survival were 15 mo(IQR 5-26 mo), 5 mo(IQR 2-13 mo)and 3 mo(IQR 1-13 mo)(P < 0.0001), respectively. Among BCLC-B patients(n =135), 57% received TACE with a median number of 2 sessions(IQR 1-3 sessions).Survival was significantly better in BCLC-B patients treated with TACE HR =0.29(CI: 0.21-0.40) than those without TACE. After tumor reassessment by RECIST 1.1 criteria following the first TACE, patients with complete response achieved longer survival (HR = 0.15(CI: 0.04-0.56, P = 0.005))Eighty-two patients were treated with sorafenib, mostly BCLC-B and C(87.8%). However,12.2% were BCLC-D. Median survival with sorafenib was 4.5 mo(IQR 2.3-11.7 mo);which was lower among BCLC-D patients 3.2 mo(IQR 2.0-14.1 mo). A total of 36 BCLC-B patients presented tumor progression after TACE. In these patients,treatment with sorafenib presented better survival when compared to those patients who received sorafenib without prior TACE [HR = 0.26(CI: 0.09-0.71);P= 0.013].CONCLUSION In this real setting, our results were lower than expected. This highlights unmet needs in Argentina, prior to the introduction of new treatments for HCC. | Federico Pinero Sebastián Marciano Nora Fernández Jorge Silva Margarita Anders Alina Zerega Ezequiel Ridruejo Gustavo Romero Beatriz Ameigeiras Claudia D’Amico Luis Gaite Carla Bermúdez Virginia Reggiardo Luis Colombato Adrián Gadano Marcelo Silva | 2019 | World Journal of Gastroenterology2019，25，27： | 3 |
| 7 | Split liver transplantation in adults显示文摘Split liver transplantation(SLT),while widely accepted in pediatrics,remains underutilized in adults. Advancements in surgical techniques and donor-recipient matching,however,have allowed expansion of SLT from utilization of the right trisegment graft to now include use of the hemiliver graft as well. Despite less favorable outcomes in the early experience,better outcomes have been reported by experienced centers and have further validated the feasibility of SLT. Importantly,more than two decades of experience have identified key requirements for successful SLT in adults. When these requirements are met,SLT can achieve outcomes equivalent to those achieved with other types of liver transplantation for adults. However,substantial challenges,such as surgical techniques,logistics,and ethics,persist as ongoing barriers to further expansion of this highly complex procedure. This review outlines the current state of SLT in adults,focusing on donor and recipient selection based on physiology,surgical techniques,surgical outcomes,and ethical issues. | koji hashimoto masato fujiki cristiano quintini federico n aucejo teresa diago uso dympna m kelly bijan eghtesad john j fung charles m miller | 2016 | World Journal of Gastroenterology2016，22，33： | 3 |
| 8 | 在与心肌的梗塞介绍的就医的病人的心率的预示的意义显示文摘 AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or < 70 bpm). Complications were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). CONCLUSION: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up. | Lorenzo Fácila Pedro Morillas Juan Quiles Federico Soria Alberto Cordero Pilar Mazón Manuel Anguita Cándido Martín-Luengo Jose Ramón Gonzalez-Juanatey Vicente Bertomeu | 2012 | World Journal of Cardiology2012，4，1： | 3 |
| 9 | Ascorbic acid and prunasin,two candidate biomarkers for endodormancy release in almond flower buds identified by a nontargeted metabolomic study显示文摘Temperate fruit trees belonging to Prunus species have the ability to suspend(induce dormancy)and resume growth periodically in response to environmental and seasonal conditions.Endodormancy release requires the long-term accumulation of chill.Upon accumulation of cultivar-specific chill requirements,plants enter the state of ecodormancy,which means the ability to grow has been restored,depending on the fulfilment of heat requirements.As many different metabolic pathways are implicated in endodormancy release,we have performed a metabolomic analysis,using the ultra-high-performance liquid chromatography–quadrupole time-of-flying(UPLC–QToF)technique.We assayed flower buds in different stages of endodormancy in four almond cultivars with different flowering times:the extra-early Desmayo Largueta,the late Antoñeta,the extra-late Penta,and the ultra-late Tardona.An orthogonal projection to latent-structure discriminant-analysis model was created to observe differences between endodormant and ecodormant flower buds.The metabolites showing the most significant variation were searched against the Metlin,HMDB,and KEGG libraries,which allowed us to identify 87 metabolites.These metabolites were subsequently assigned to specific pathways,such as abscisic acid biosynthesis,phenylpropanoid biosynthesis,and D-sorbitol metabolism,among others.The two metabolites that exhibited the most significant variations in all the cultivars studied with fold changes of up to 6.49 were ascorbic acid and prunasin.For the first time,these two metabolites have been proposed as potential biomarkers for endodormancy release in almond.Given the high synteny present between the Rosaceae species,these results could be extrapolated to other important crops like peach,plum,cherry,or apricot,among others. | Jesús Guillamón Guillamón Ángela Sánchez Prudencio JoséEnrique Yuste Federico Dicenta Raquel Sánchez-Pérez | 2020 | Horticulture Research2020，7，1： | 2 |
| 10 | Short-term effects of different fire severities on soil properties and Pinus halepensis regeneration显示文摘Considering that diverse fire severities can affect soil properties differently,the aim of this study was to examine to what extent changes in soil properties caused by fire could condition seedling establishment.This new approach is for identifying a new fire cause-effect chain to qualify the impacts of fire on soils with the purpose of using fire as a tool in forest management to favour Pinus halepensis Mill.regeneration.The study area was a reforested P.halepensis area which had been crossed by fire for78.8 ha,causing various degrees of damage.The forest was subdivided into three large areas according to the gravity of crown scorch,[low(LS),medium(MS)and high(HS)severity],on the basis of needle yellowing which usually occurs after exposure to direct flames.Results showed significant differences in soil properties with respect to fire severity.In the HS area,total nitrogen and carbon were considerably reduced while ash and phosphorus contents significantly increased.The changes in soil properties,in particular to nutrient levels,affected P.halepensis regeneration,mainly the first year after the fire.Greater regeneration occurred in areas affected by moderate fire severity in which the temperatures reached increased the mineralization of soil organic matter with the consequent release of nutrients available for seedling growth.Additionally,moderate fire severity suppressed the regeneration of grasses,reducing the interspecific competition.Heights of seedlings were inversely proportional to the density of grasses.Where the number was abundant(LS),the height was modest;conversely,where the number was low(HS),the greater hypsometric differentiation of pine seedlings was observed.These results suggest that moderate fire severity represents an environmental stress(hormesis)altering microscale conditions to increase pine germination and establishment.The exposure of P.halpensis to a moderate environmental factor that is damaging at higher intensities,induces an adaptive beneficial effect on seedling regeneration.This data can re-evaluate the assertion that coniferous burned areas,if left unmanaged,would remain unproductive for an indefinite period. | Federico Romeo Pasquale A.Marziliano Maria Belén Turrión Adele Muscolo | 2020 | Journal of Forestry Research2020，31，4： | 2 |

| 14 | Influence of Livestock Soil Eutrophication on Floral Composition in the Pyrenees Mountains显示文摘Livestock behaviour in the Pyrenees includes free grazing and a long resting period that provokes the accumulation of dung and urine in some places,so-called camping areas. The aims of this study were (i) to analyze any change in floral composition,and in nutritional and chemical contents of plants in a livestock camping area; and (ii) to relate the floral composition with soil chemical properties. In a linear transect,five sampling zones were established,from the centre of the camping area to the surrounding Nardus stricta-dominant pasture. The above ground plant biomass and the topsoil were sampled in each zone with 6 replicates per zone. Plant species were classified and weighed to calculate above ground biomass,nutritional and chemical contents,and Shannon diversity and evenness indices. Additionally,soils were sampled in two periods,at the beginning and at the end of grazing period. Soil available nutrients (nitrate,ammonium,phosphorus,potassium,calcium and magnesium),total nitrogen,organic carbon and pH were measured. Plant chemical contents (protein,lignin and others) were significantly related to the proportions of grasses,legumes and other plants; so,the protein content is positively correlated with legumes plant biomass while lignin content is negatively correlated with grasses. Both plant and soil nutrients increased linearly towards the centre of the camping area. However,the relationship among plant species richness,diversity and evenness relative to its position along the studied transect was bell-shaped. From the outskirts to the centre of the camping area,plants with low nutrient demand were progressively replaced by those with medium and high nutrients demand and by pioneers. Nardus stricta-dominant pasture has low plant diversity and plant nutrient content as well as a poor soil nutrient availability. The presence of the camping area introduced patches with more soil nutrients and new species in the large spatial scale. However at a small spatial scale,the strong soil nutrient concentration into the centre of the camping area reduced floral composition again. To ensure positive effects of camping areas on plant diversity,and to manage more effectively the nutrients returned to the soil,a reduction in the stocking rate should be pursued. | BADíA David MARTí Clara SáNCHEZ José Ramón FILLAT Federico AGUIRRE Javier GóMEZ Daniel | 2008 | Journal of Mountain Science2008，5，1： | 1 |
