| 1 | Fat:A matter of disturbance for the immune system显示文摘Obesity is increasingly being recognized as a risk factor for a number of benign and malignant gastrointestinal conditions. However, literature on the underlying pathophysiological mechanisms is sparse and ambiguous. There is compelling evidence that both overnutrition and undernutrition negatively interfere with the immune system. Overnutrition has been found to increase susceptibility to the development of inflammatory diseases, autoimmune diseases and cancer. In the regulation of immune and in? ammatory processes, white adipose tissue plays a critical role, not only as an energy store but also as an important endocrine organ. The obese state is characterised by a low-grade systemic in? ammation, mainly as a result of increased adipocytes as well as fat resident-and recruited-macrophage activity. In the past few years, various products of adipose tissue including adipokines and cytokines have been characterised and a number of pathways linking adipose tissue metabolism with the immune system have been identified. Activation of the innate immune system plays a major role in hepatic steatosis. Non-alcoholic fatty liver disease includes a wide spectrum of diseases, from pure steatosis to non-alcoholic steato-hepatitis in the absence of signif icant alcohol consumption. Although steatosis is considered a non-progressive disease, non-alcoholic steatohepatitis may deteriorate in advanced chronic liver diseases, cirrhosis, and hepatocellular carcinoma. An important parallel between obesityrelated pathology of adipose tissue and liver pertains to the emerging role of macrophages, and growing evidence suggests that Kupffer cells critically contribute to progression of non-alcoholic fatty liver disease. Moreover, a close link between specif ic immune activation and atherosclerosis has been well established, suggesting that fat can directly trigger immune responses. This review discusses the role of fat as 'a matter of disturbance for the immune system' with a focus on hepatic steatosis. | Alessandro Federico Elena D’Aiuto Francesco Borriello Giusi Barra Antonietta Gerarda Gravina Marco Romano Raffaele De Palma | 2010 | World Journal of Gastroenterology2010，16，38： | 12 |
| 2 | Attenuation of dextran sodium sulphate induced colitis in matrix metalloproteinase-9 deficient mice显示文摘AIM: To study whether matrix metalloproteinase-9 (MMP-9) is a key factor in epithelial damage in the dextran sodium sulphate (DSS) model of colitis in mice.METHODS: MMP-9-deficient and wild-type (wt) mice were given 5% DSS in drinking water for 5 d followed by recovery up to 7 d. On d 5 and 12 after induction of colitis, gelatinases, MMP-2 and MMP-9, were measured in homogenates of colonic tissue by zymography and Western blot, whereas tissue inhibitor of metalloproteinases (TIMPs) were measured by reverse zymography. The gelatinolytic activity was also determined in supernatants of polymorphonuclear leukocytes (PMN) isolated from mice blood. Moreover, intestinal epithelial cells were stimulated with TNF-α to study whether these cells were able to produce MMPs. Finally, colonic mucosal lesions were measured by microscopic examination. RESULTS: On d 5 of colitis, the activity of MMP-9 was increased in homogenates of colonic tissues (0.24 ± 0.1 vs 21.3 ± 6.4, P < 0.05) and PMN from peripheral blood in wt (0.5 ± 0.1 vs 10.4 ± 0.7, P < 0.05), but not in MMP-9-deficient animals. The MMP-9 activity was also up-regulated by TNF-α in epithelial intestinal cells (2.5 ± 0.5 vs 14.7 ± 3.0, P < 0.05). Although colitis also led to increase of TIMP-1 activity, the MMP-9/TIMP-1 balance remained elevated. Finally, in the MMP-9-deficient colitic mice both the extent and severity of intestinal epithelialinjury were significantly attenuated when compared with wt mice. CONCLUSION: We conclude that DSS induced colitis is markedly attenuated in animals lacking MMP-9. This suggests that intestinal injury induced by DSS is modu-lated by MMP-9 and that inhibition of this gelatinase may reduce inflammation. | Alfredo Santana Carlos Medina Maria Cristina Paz-Cabrera Federico Díaz-Gonzalez Esther Farré Antonio Salas Marek W Radomski Enrique Quintero | 2006 | World Journal of Gastroenterology2006，12，40： | 9 |
| 3 | Peritoneal seeding from appendiceal carcinoma:A case report and review of the literature显示文摘Non-carcinoid appendiceal malignancies are rare entities,representing less than 0.5% of all gastrointestinal malignancies.Because of their rarity and particular biological behavior,a substantial number of patients affected by these neoplasms do not receive appropriate surgical resection.In this report,we describe a rare case of primary signetring cell carcinoma of the appendix with peritoneal seeding which occurred in a 40-year old man admitted at the Emergency Surgery Department with the clinical suspicion of acute appendicitis.After a surgical debulking and right hemicolectomy,the patient had systemic chemotherapy according to FOLFOX protocol.After completion of the latter,the patient underwent cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.This report offers a brief review of the literature and suggests an algorithm for the management of non-carci-noid appendiceal tumors with peritoneal dissemination. | Valentina R Bertuzzo Federico Coccolini Antonio D Pinna | 2010 | World Journal of Gastrointestinal Surgery2010，2，8： | 6 |
| 4 | 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 |
| 5 | 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 |

| 10 | Long-term survival of patients with stage Ⅱ and Ⅲgastric cancer who underwent gastrectomy with inadequate nodal assessment显示文摘BACKGROUND Gastric cancer is an aggressive disease with frequent lymph node(LN)involvement.The NCCN recommends a D2 lymphadenectomy and the harvesting of at least 16 LNs.This threshold has been the subject of great debate,not only for the extent of surgery but also for more appropriate staging.The reclassification of stage IIB through IIIC based on N3b nodal staging in the eighth edition of the American Joint Committee on Cancer(AJCC)staging system highlights the efforts to more accurately discriminate survival expectancy based on nodal number.Furthermore,studies have suggested that pathologic assessment of 30 or more LNs improve prognostic accuracy and is required for proper staging of gastriccancer.AIM To evaluate the long-term survival of advanced gastric cancer patients who deviated from expected survival curves because of inadequate nodal evaluation.METHODS Eligible patients were identified from the Surveillance,Epidemiology,and End Results database.Those with stage II-III gastric cancer were considered for inclusion.Three groups were compared based on the number of analyzed LNs.They were inadequate LN assessment(ILA,<16 LNs),adequate LN assessment(ALA,16-29 LNs),and optimal LN assessment(OLA,≥30 LNs).The main outcomes were overall survival(OS)and cancer-specific survival.Data were analyzed by the Kaplan-Meier product-limit method,log-rank test,hazard risk,and Cox proportional univariate and multivariate models.Propensity score matching(PSM)was used to compare the ALA and OLA groups.RESULTS The analysis included 11607 patients.Most had advanced T stages(T3=48%;T4=42%).The pathological AJCC stage distribution was IIA=22%,IIB=18%,IIIA=26%,IIIB=22%,and IIIC=12%.The overall sample divided by the study objective included ILA(50%),ALA(35%),and OLA(15%).Median OS was 24 mo for the ILA group,29 mo for the ALA group,and 34 mo for the OLA group(P<0.001).Univariate analysis showed that the ALA and OLA groups had better OS than the ILA group[ALA hazard ratio(HR)=0.84,95%confidence interval(CI):0.79-0.88,P<0.001 and OLA HR=0.73,95%CI:0.68-0.79,P<0.001].The OS outcome was confirmed by multivariate analysis(ALA HR=0.68,95%CI:0.64-0.71,P<0.001 and OLA:HR=0.48,95%CI:0.44-0.52,P<0.001).A 1:1 PSM analysis in 3428 patients found that the OLA group had better survival than the ALA group(OS:OLA median=34 mo vs ALA median=26 mo,P<0.001,which was confirmed by univariate analysis(HR=0.81,95%CI:0.75-0.89,P<0.001)and multivariate analysis:(HR=0.71,95%CI:0.65-0.78,P<0.001).CONCLUSION Proper nodal staging is a critical issue in gastric cancer.Assessment of an inadequate number of LNs places patients at high risk of adverse long-term survival outcomes. | Jacopo Desiderio Andrea Sagnotta Irene Terrenato Eleonora Garofoli Claudia Mosillo Stefano Trastulli Federica Arteritano Federico Tozzi Vito D'Andrea Yuman Fong Yanghee Woo Sergio Bracarda Amilcare Parisi | 2021 | World Journal of Gastrointestinal Surgery2021，13，11： | 2 |
