| 1 | Device-associated infection rates, mortality, length of stay and bacterial resistance in intensive care units in Ecuador: International Nosocomial Infection Control Consortium's findings显示文摘AIM To report the results of the International Nosocomial Infection Control Consortium(INICC) study conducted in Quito, Ecuador.METHODS A device-associated healthcare-acquired infection(DAHAI) prospective surveillance study conducted from October 2013 to January 2015 in 2 adult intensive care units(ICUs) from 2 hospitals using the United States Centers for Disease Control/National Healthcare Safety Network(CDC/NHSN) definitions and INICC methods. RESULTS We followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection(CLABSI) rate was 6.5 per 1000 central line(CL)-days, the ventilator-associated pneumonia(VAP) rate was 44.3 per 1000 mechanical ventilator(MV)-days, and the catheterassociated urinary tract infection(CAUTI) rate was 5.7 per 1000 urinary catheter(UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9(CLABSI) and 5.3(CAUTI)] and higher than NHSN rates [0.8(CLABSI) and 1.3(CAUTI)]- although device use ratios for CL and UC were higher than INICC and CDC/NSHN's ratios. By contrast, despite the VAP rate was higher than INICC(16.5) and NHSN's rates(1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI. CONCLUSION DA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates. | Estuardo Salgado Yepez Maria M Bovera Victor D Rosenthal Hugo A González Flores Leonardo Pazmino Francisco Valencia Nelly Alquinga Vanessa Ramirez Edgar Jara Miguel Lascano Veronica Delgado Cristian Cevallos Gasdali Santacruz Cristian Pelaéz Celso Zaruma Diego Barahona Pinto | 2017 | World Journal of Biological Chemistry2017，8，1： | 23 |
| 2 | Prognostic factors and time-related changes influence results of colorectal liver metastases surgical treatment:A single-center analysis显示文摘AIM:To analyze the prognostic factors involved in survival and cancer recurrence in patients undergoing surgical treatment for colorectal liver metastases(CLM) and to describe the effects of time-related changes on survival and recurrence in these patients.METHODS:From January 1994 to January 2006,236 patients with CLM underwent surgery with the aim of performing curative resection of neoplastic disease at our institution and 189(80%) of these patients underwent resection of CLM with curative intention.Preoperative,intraoperative and postoperative data,including primary tumor and CLM pathology results,were retrospectively reviewed.Patients were divided into two time periods:a first period from January 1994 to January 2000(n = 93),and a second period from February 2000 to January 2006(n = 143).RESULTS:Global survival at 1,3 and 5 years in patients undergoing hepatic resection was 91%,54% and 47%,respectively.Patients with preoperative extrahepatic disease,carcinoembryonic antigen(CEA) levels over 20 ng/dL,more than four nodules or extrahepatic invasion at pathological analysis had worse survival.Tumor recurrence rate at 1 year was 48.3%,being more frequent in patients with preoperative and pathological extrahepatic disease and CEA levels over 20 ng/dL.Although patients in the second time period had more adverse prognostic factors,no differences in overall survival and recurrence were observed between the two periods.CONCLUSION:Despite advances in surgical technique and better adjuvant treatments and preoperative imaging,careful patient staging and selection is crucial to continue offering a chance of cure to patients with CLM. | Josep Martí María Marta Modolo Josep Fuster Jaume Comas Rebeca Cosa Joana Ferrer Victor Molina Juan Romero Constantino Fondevila Ramón Charco Juan Carlos García-Valdecasas | 2009 | World Journal of Gastroenterology2009，15，21： | 9 |

| 9 | Current endoscopic approach to indeterminate biliary strictures显示文摘Biliary strictures are considered indeterminate when basic work-up, including transabdominal imaging and endoscopic retrograde cholangiopancreatography with routine cytologic brushing, are non-diagnostic. Indeterminate biliary strictures can easily be mischaracterized which may dramatically affect patient's outcome. Early and accurate diagnosis of malignancy impacts not only a patient's candidacy for surgery, but also potential timely targeted chemotherapies. A significant portion of patients with indeterminate biliary strictures have benign disease and accurate diagnosis is, thus, paramount to avoid unnecessary surgery. Current sampling strategies have suboptimal accuracy for the diagnosis of malignancy. Emerging data on other diagnostic modalities, such as ancillary cytology techniques, single operator cholangioscopy, and endoscopic ultrasonography-guided fine needle aspiration, revealed promising results with much improved sensitivity. | David W Victor Stuart Sherman Tarkan Karakan Mouen A Khashab | 2012 | World Journal of Gastroenterology2012，18，43： | 3 |
| 10 | H pylori receptor MHC classⅡcontributes to the dynamic gastric epithelial apoptotic response显示文摘AIM: To investigate the role of MHC classⅡin the modulation of gastric epithelial cell apoptosis induced by H pylon infection. METHODS: After stimulating a human gastric epithelial cell line with bacteria or agonist antibodies specific for MHC classⅡand CD95, the quantitation of apoptotic and anti-apoptotic events, including caspase activation, BCL-2 activation, and FADD recruitment, was performed with a fluorometric assay, a cytometric bead array, and confocal microscopy, respectively. RESULTS: Pretreatment of N87 cells with the anti-MHC classⅡIgM antibody RFD1 resulted in a reduction in global caspase activation at 24 h of H pylori infection. When caspase 3 activation was specifically measured, crosslinking of MHC class n resulted in markedly reduced caspase activation, while simple ligation of MHC classⅡdid not. Crosslinking of MHC class n also resulted in an increased activation of the anti-apoptosis molecule BCL-2 compared to simple ligation. Confocal microscope analysis demonstrated that the pretreatment of gastric epithelial cells with a crosslinking anti-MHC classⅡIgM blocked the recruitment of FADD to the cell surface. CONCLUSION: The ability of MHC class n to modulate gastric epithelial apoptosis is at least partially dependent on its crosslinking. The crosslinking of this molecule has anti-apoptotic effects during the earlier time points of H pylori infection. This effect is possibly mediated by the ability of MHC classⅡto modulate the activation of the pro-apoptotic receptor Fas by blocking the recruitment of the accessory molecule FADD, and this delay in apoptosis induction could allow for prolonged cytokine secretion by H pylori-infected gastric epithelial cells. | David A Bland Giovanni Suarez Ellen J Beswick Johanna C Sierra Victor E Reyes | 2006 | World Journal of Gastroenterology2006，12，29： | 3 |
| 11 | Conservative management of perforated duodenal diverticulum: A case report and review of the literature显示文摘Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs. | David Martínez-Cecilia Alvaro Arjona Sánchez Manuel Gómez álvarez Eva Torres Tordera Antonio Luque Molina Victor Valentí Azcárate Javier Briceo Delgado Francisco Javier Padillo Pedro López-Cillero Sebastián Rufián Pea | 2008 | World Journal of Gastroenterology2008，14，12： | 2 |
| 12 | Interferon-β induced in female genital epithelium by HIV-1 glycoprotein 120 via Toll-like-receptor 2 pathway acts to protect the mucosal barrier显示文摘More than 40%of HIV infections occur via female reproductive tract(FRT)through heterosexual transmission.Epithelial cells that line the female genital mucosa are the first line of defense against HIV-1 and other sexually transmitted pathogens.These sentient cells recognize and respond to external stimuli by induction of a range of carefully balanced innate immune responses.Previously,we have shown that in response to HIV-1 gp120,the genital epithelial cells(GECs)from upper reproductive tract induce an inflammatory response that may facilitate HIV-1 translocation and infection.In this study,we report that the endometrial and endocervical GECs simultaneously induce biologically active interferon-β(IFNβ)antiviral responses following exposure to HIV-1 that act to protect the epithelial tight junction barrier.The innate antiviral response was directly induced by HIV-1 envelope glycoprotein gp120 and addition of gp120 neutralizing antibody inhibited IFNβproduction.Interferon-βwas induced by gp120 in upper GECs through Toll-like receptor 2 signaling and required presence of heparan sulfate on epithelial cell surface.The induction of IFNβwas dependent upon activation of transcription factor IRF3(interferon regulatory factor 3).The IFNβwas biologically active,had a protective effect on epithelial tight junction barrier and was able to inhibit HIV-1 infection in TZM-bl indicator cells and HIV-1 replication in T cells.This is the first report that recognition of HIV-1 by upper GECs leads to induction of innate antiviral pathways.This could explain the overall low infectivity of HIV-1 in the FRT and could be exploited for HIV-1 prophylaxis. | Aisha Nazli Sara Dizzell Muhammad Atif Zahoor Victor H Ferreira Jessica Kafka Matthew William Woods Michel Ouellet Ali A Ashkar Michel J Tremblay Dawn ME Bowdish Charu Kaushic | 2019 | Cellular & Molecular Immunology2019，16，2： | 2 |
