1Diagnosis and treatment of hepatocellular carcinoma: An update显示文摘Hepatocellular carcinoma(HCC) is one of the most common malignancies leading to high mortality rates in the general population; in cirrhotic patients, it is the primary cause of death. The diagnosis is usually delayed in spite of at-risk population screening recommendations, i.e., patients infected with hepatitis B or C virus. Hepatocarcinogenesis hinges on a great number of genetic and molecular abnormalities that lead to tumor angiogenesis and foster their dissemination potential. The diagnosis is mainly based on imaging studies such as computed tomography and magnetic resonance, in which lesions present a characteristic classical pattern of early arterial enhancement followed by contrast medium 'washout' in late venous phase. On occasion, when imaging studies are not conclusive, biopsy of the lesion must be performed to establish the diagnosis. The Barcelona Clinic Liver Cancer staging method is the most frequently used worldwide and recommended by the international guidelines of HCC management. Currently available treatments include tumor resection, liver transplant, sorafenib and locoregional therapies(alcoholization, radiofrequency ablation, chemoembolization). The prognosis of hepatocarcinoma is determined according to the lesion's stage and in cirrhotic patients, on residual liver function. Curative treatments, such as liver transplant, are sought in patients diagnosed in early stages; patients in more advanced stages, were not greatly benefitted by chemotherapy in terms of survival until the advent of target molecules such as sorafenib.Javier Tejeda-Maldonado Ignacio García-Juárez Jonathan Aguirre-Valadez Adrián González-Aguirre Mario Vilatobá-Chapa Alejandra Armengol-Alonso Francisco Escobar-Penagos Aldo Torre Juan Francisco Sánchez-ávila Diego Luis Carrillo-Pérez 2015World Journal of Hepatology2015,7,3:22
2Subclinical abnormal glucose tolerance is a predictor of death in liver cirrhosis显示文摘AIM:To determine if subclinical abnormal glucose tolerance(SAGT)has influence on survival of non-diabetic patients with liver cirrhosis.METHODS:In total,100 patients with compensatedliver cirrhosis and normal fasting plasma glucose were included.Fasting plasma insulin(FPI)levels were measured,and oral glucose tolerance test(OGTT)was performed.According to OGTT results two groups of patients were formed:those with normal glucose tolerance(NGT)and those with SAGT.Patients were followed every three months.The mean follow-up was932 d(range of 180-1925).Survival was analyzed by the Kaplan-Meyer method,and predictive factors of death were analyzed using the Cox proportional hazard regression model.RESULTS:Of the included patients,30 showed NGT and70 SAGT.Groups were significantly different only in age,INR,FPI and HOMA2-IR.Patients with SAGT showed lower 5-year cumulated survival than NGT patients(31.7%vs 71.6%,P=0.02).Differences in survival were significant only after 3 years of follow-up.SAGT,Child-Pugh B,and high Child-Pugh and Model for EndStage Liver Disease(MELD)scores were independent predictors of death.The causes of death in 90.3%of cases were due to complications related to liver disease.CONCLUSION:SAGT was associated with lower survival.SAGT,Child-Pugh B,and high Child-Pugh and MELD scores were independent negative predictors of survival.Diego García-Compeán Joel Omar Jáquez-Quintana Fernando Javier Lavalle-González José Alberto González-González Linda Elsa Mu?oz-Espinosa Jesús Zacarías Villarreal-PérezEndocrinology Service and Department of Internal Medicine University Hospital 'Dr. José E.

3Hepatogenous diabetes: Is it a neglected condition in chronic liver disease?显示文摘Diabetes mellitus(DM) that occurs because of chronic liver disease(CLD) is known as hepatogenous diabetes(HD). Although the association of diabetes and liver cirrhosis was described forty years ago, it was scarcely studied for long time. Patients suffering from this condition have low frequency of risk factors of type 2 DM. Its incidence is higher in CLD of viral, alcoholic and cryptogenic etiology. Its pathophysiology relates to liver damage, pancreatic dysfunction, interactions between hepatitis C virus(HCV) and glucose metabolism mechanisms and genetic susceptibility. It associates with increased rate of liver complications and hepatocellular carcinoma, and decreased 5-year survival rate. It reduces sustained virological response in HCV infected patients. In spite of these evidences, the American Diabetes Association does not recognize HD. In addition, the impact of glucose control on clinical outcomes of patients has not been evaluated. Treatment of diabetes may be difficult due to liver insufficiency and hepatotoxicity of antidiabetic drugs. Notwithstanding, no therapeutic guidelines have been implemented up to date. In this editorial, authors discuss the reasons why they think that HD may be a neglected pathological condition and call attention to the necessity for more clinical research on different fields of this disease.Diego García-Compeán José Alberto González-González Fernando Javier Lavalle-González Emmanuel Irineo González-Moreno Jesús Zacarías Villarreal-Pérez Héctor Jesús Maldonado-Garza 2016World Journal of Gastroenterology2016,22,10:12
4Diagnostic and therapeutic challenges of gastrointestinal angiodysplasias: A critical review and view points显示文摘Gastrointestinal angiodysplasias (GIADs), also called angioectasias, are the most frequent vascular lesions. Its precise prevalence is unknown since most of them are asymptomatic. However, the incidence may be increasing since GIADs affect individuals aged more than 60 years and population life expectancy is globally increasing worldwide. They are responsible of about 5% to 10% of all gastrointestinal bleeding (GIB) cases. Most GIADs are placed in small bowel, where are the cause of 50 to 60% of obscure GIB diagnosed with video capsule endoscopy. They may be the cause of fatal severe bleeding episodes;nevertheless, recurrent overt or occult bleeding episodes requiring repeated expensive treatments and disturbing patient’s quality-of-life are more frequently observed. Diagnosis and treatment of GIADs (particularly those placed in small bowel) are a great challenge due to insidious disease behavior, inaccessibility to affected sites and limitations of available diagnostic procedures. Hemorrhagic causality out of the actively bleeding lesions detected by diagnostic procedures may be difficult to establish. No treatment guidelines are currently available, so there is a high variability in the management of these patients. In this review, the epidemiology and pathophysiology of GIADs and the status in the diagnosis and treatment, with special emphasis on small bowel angiodysplasias based on multiple publications, are critically discussed. In addition, a classification of GIADs based on their endoscopic characteristics is proposed. Finally, some aspects that need to be clarified in future research studies are highlighted.Diego García-Compeán ángel N Del Cueto-Aguilera Alan R Jiménez-Rodríguez José A González-González Héctor J Maldonado-Garza 2019World Journal of Gastroenterology2019,25,21:5
5Nutritional evaluation of integral cassava root silages for growing pigs显示文摘The experiment aimed at determining the nutritional value of integral cassava root silages with yogurt as inoculant or wastewater(manipueira) by liquid addition ensiling process. Eighteen crossbred piglets(Large White x Landrace), castrated males with an initial average weight of 50 kg were allocated in metabolism cages throughout 11-day trial duration(6 days for animal's adaptation to the cages and to the experimental diets, and 5 days of urine and faeces collection). The experimental design was a randomized block arrangement with 3 treatments and 6 replicates: basal diet(100%); mixture composed of75% basal diet and 25% integral cassava root silage with yogurt as inoculant; a mixture composed of 75%of basal diet and 25% integral cassava root silage with wastewater. The silages with wastewater and yogurt presented the following values of apparent digestibility of dry matter 89.96% and 90.01%,apparent digestibility of crude protein of 60.67% and 66.43%, apparent digestibility of gross energy of90.43% and 91.48%, gross energy metabolizability coefficients of 87.88% and 88.93%, digestible energy values of 3,705 and 3,783 kcal/kg on a dry matter(DM) basis, and metabolizable energy values of 3,600 and 3,676 kcal/kg DM, respectively. The results have demonstrated that integral cassava root silages with wastewater or yogurt have a high nutritional value and can be used as an alternative energy source in growing pig's diets.Diego D.Araújo Alessandro B.Amorim Mayra A.D.Saleh Felipe Curcelli Pedro L.Perdigón Silvio J.Bicudo Dirlei A.Berto 2016Animal Nutrition2016,,3:5
6Clinical implications of diabetes in chronic liver disease:Diagnosis,outcomes and management,current and future perspectives显示文摘Diabetes mellitus(DM)is common in liver cirrhosis(LC).The pathophysiological association is bidirectional.DM is a risk factor of LC and LC is a diabetogenic condition.In the recent years,research on different aspects of the association DM and LC has been intensified.Nevertheless,it has been insufficient and still exist many gaps.The aims of this review are:(1)To discuss the latest understandings of the association of DM and LC in order to identify the strategies of early diagnosis;(2)To evaluate the impact of DM on outcomes of LC patients;and(3)To select the most adequate management benefiting the two conditions.Literature searches were conducted using Pub Med,Ovid and Scopus engines for DM and LC,diagnosis,outcomes and management.The authors also provided insight from their own published experience.Based on the published studies,two types of DM associated with LC have emerged:Type 2 DM(T2 DM)and hepatogenous diabetes(HD).High-quality evidences have determined that T2 DM or HD significantly increase complications and death pre and post-liver transplantation.HD has been poorly studied and has not been recognized as a complication of LC.The management of DM in LC patients continues to be difficult and should be based on drug pharmacokinetics and the degree of liver failure.In conclusion,the clinical impact of DM in outcomes of LC patients has been the most studied item recently.Nevertheless many gaps still exist particularly in the management.These most important gaps were highlighted in order to propose future lines for research.Diego García-Compeán Emanuela Orsi Ramesh Kumar Felix Gundling Tsutomu Nishida Jesús Zacarías Villarreal-Pérez Ángel N Del Cueto-Aguilera JoséA González-González Giuseppe Pugliese 2022World Journal of Gastroenterology2022,28,8:4
7Diabetic gastroenteropathy:An underdiagnosed complication显示文摘This article is an extensive review that provides an update on the pathophysiology,symptoms,diagnosis,and treatment of diabetic gastroenteropathy.There is no reported prevalence,but it has been described that patients with type 1 diabetes have a cumulative incidence at 10 years of 5.2%,and type 2 patients,1%.Also,in the group of type 1 diabetes,it has been observed that women are more likely to present this condition(5.8%vs 3.5%).Many factors are associate with its development(e.g.,hyperglycemia,vagal dysfunction,loss of expression of neural nitric oxide synthase in the myenteric plexus,alterations in the Cajal interstitial cell network,and oxidative stress).Gastrointestinal discomfort could be perceived 70% higher in diabetic patients,describing that 25%of diabetic patients experience gastrointestinal symptoms.Diabetic enteropathy could affect any portion of the gastrointestinal tract,but esophageal alterations were described in more than 60% of diabetic patients,also 60% of them present constipation,and 20%,diarrhea.Gastric emptying scintigraphy is useful to evaluate gastroparesis,therefore,gastric retention of more than 60%at 2 h has a sensitivity of 100% and specificity of 20% for diagnosis;however,other studies such as breath tests,with a sensitivity of 89% and a specificity of 80%,or the endoscopic capsule contribute to the diagnosis.There is no cure;however,management must be multidisciplinary,focused on slowing the progression of diabetic gastroenteropathy,reducing symptoms,and restoring function;that includes nutritional recommendation,maintain glucose levels kept below 180 mg/dL,use of prokinetics,anti-emetics;nowadays,it has been special interest in surgical treatment,such as pyloroplasty,also gastric electrical stimulation appears to be another alternative.Marcio JoséConcepción Zavaleta Jhean Gabriel Gonzáles Yovera Diego Martín Moreno Marreros Luciana del Pilar Rafael Robles Kely Roxana Palomino Taype Karen Nohelly Soto Gálvez Luis Fernando Arriola Torres Julia Cristina Coronado Arroyo Luis Alberto Concepción Urteaga 2021World Journal of Diabetes2021,12,6:4
8Detection of flock movement and behaviour of broiler chickens at different feeders using image analysis显示文摘The behaviour of broiler chickens has been extensively studied as a function of stocking density and environmental conditions,but limited information was reported in the scientific literature about the effect of feeder type on birds’feeding process.The main objective of this study was to assess the effects of three different feeder types in relation to the birds’behaviour in its surroundings.The analysed feeders were:tube-type with partition grid(F1);tube-type without partition grid(F2);and automatic type with partition grid(F3).The considered variables were:occupied area(OA);activity index(AI)(flock movement);total birds presented in the area(TB);and birds effectively eating(EE).OA and AI were calculated by computational image analysis while TB and EE were manually measured.The results indicated that the feeder type could have influenced the birds’behaviour regarding to OA(R2=0.56),TB(R2=0.48),and EE(R2=0.40),but AI(R2=0.01)was not found to be directly influenced by the feeder type.A higher percentage of birds effectively eating were found in F2(86.4%),which was the one with the largest free area to access the feed.Similar average number of total birds was found in F1,but with a lower percentage of individuals effectively eating(63.3%),which means that birds were nearby this feeder performing other behaviours.Since the assessed feeders were in the same house under the same conditions,it can be suggested that not only the free area to access the feed but potentially the design of feeders could have influenced the birds’feeding preference.The real beneficial effect of the adoption of partition grid on feed trays is still uncertain,and it is also unclear whether the financial value of reduced wastage would compensate the possible reduction in feed intake.Diego Pereira Neves Saman Abdanan Mehdizadeh Matthew Tscharke Irenilza de Alencar Nääs Thomas Michael Banhazi 2015Information Processing in Agriculture2015,2,3:4
9Tribological performance of tributylmethylammonium bis(trifluoromethylsulfonyl)amide as neat lubricant and as an additive in a polar oil显示文摘The ionic liquid(IL) tributylmethylammonium bis(trifluoromethylsulfonyl)amide([N4441][NTf2]) was used as neat lubricant and as an additive(1.5 wt%) in a polar oil to study its friction and wear reducing properties.Tribological tests were completed for 90 minutes at room temperature and 100 °C in a reciprocating configuration at loads of 30 and 70 N,10 Hz-frequency,and 4 mm stroke length.Wear volume was measured by confocal microscopy and the surface-IL interaction determined by XPS.The main findings were that neat IL showed the best tribological behavior;the IL-containing mixture behaved similar to the base oil regarding friction,however outperformed the antiwear behavior of the base oil under higher temperature;surface-IL chemical interaction was found mainly at 100 °C.Rubén GONZáLEZ Diego RAMOS David BLANCO Alfonso FERNáNDEZ-GONZáLEZ Jose L.VIESCA Mark HADFIELD Antolin HERNáNDEZ BATTEZ 2019Friction2019,7,3:3
10Pupal emergence pattern in cactophilic Drosophila and the effect of host plants显示文摘Drosophila buzzatii and D.koepferae are sibling cactophilie species.The former breeds primarily on prickly pears (genus Opuntia)whereas the latter breeds on columnar cacti of the genera Cereus and Trichocereus,although with certain degree of niche overlapping.We examined the interspecific differences in diurnal temporal patterns of adult emergence from puparia and evaluated whether this behavior is affected by rearing in the different cactus hosts available in nature.We detected important host-dependent genetic variation for this trait differentially affecting the emergence schedule of these species.Diumal pattern of emergence time was directly correlated with developmental time and negatively correlated with adult wing size,suggesting that early emergences are at least indirectly correlated with increased fitness.We discussed our results in terms of their putative effects on fitness and the genetic-metabolic pathways that would be presumably affected by host's nutritional-chemical differences.Eduardo M.Soto Julián Padrò Pablo Milla Carmona Diego T.Tuero Valeria P.Carreira Ignacio M.Soto 2018Insect Science2018,25,6:3

12Efficacy of bevacizumab-containing chemotherapy in metastatic colorectal cancer and CXCL5 expression: Six case reports显示文摘BACKGROUND In metastatic colorectal cancer(mCRC),the anti-vascular endothelial growth factor drug bevacizumab(BVZ)plus chemotherapy significantly improves progression-free survival compared to chemotherapy(CT)alone.This benefit is not,however,observed in all patients.While increased chemokine CXCL5 gene expression promoting angiogenesis has been proposed as a prognostic mCRC biomarker,few studies have examined its relationship with drug efficacy.This study sought to analyze tumor CXCL5 gene expression in six patients with different efficacy of BVZ-containing CT in terms of the tumor response to treatment.CASE SUMMARY We report six cases of stage IV KRAS-mutated mCRC.Patients were given first line treatment with BVZ-containing chemotherapy in University Hospital of Fuenlabrada.The six patients differed in terms of primary tumor location(right/left side),tumor burden(mostly hepatic and peritoneal disease)and clinical disease course.Before treatment onset,total RNA was isolated from paraffinated tumor biopsy specimens and CXCL5 gene expression quantified through conventional RT-qPCR procedures.Our main finding was that CXCL5 expression levels were several times higher in three patients with lower progression free survival(under 6 mo)from the start of treatment.CONCLUSION A higher expression of CXCL5 was observed in the three patients showing worse tumor response to treatment.Apolonia Novillo María Gaibar Alicia Romero-Lorca María Fuencisla Gilsanz Laura Beltrán Miguel Galán Beatriz Antón Diego Malón Amalia Moreno Ana Fernández-Santander 2020World Journal of Gastroenterology2020,26,16:2

14在经历 transcatheter 的病人的 atrial 纤维性颤动的临床、预示的含意大动脉的阀门培植显示文摘 AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-Valero Guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio Garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose María Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón 2012World Journal of Cardiology2012,4,1:2
