| 2 | 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 |

| 4 | Design of 16S rRNA gene primers for 454 pyrosequencing of the human foregut microbiome显示文摘AIM:To design and validate broad-range 16S rRNA primers for use in high throughput sequencing to classify bacteria isolated from the human foregut microbiome.METHODS:A foregut microbiome dataset was constructed using 16S rRNA gene sequences obtained from oral,esophageal,and gastric microbiomes produced by Sanger sequencing in previous studies represented by 219 bacterial species.Candidate primers evaluated were from the European rRNA database.To assess the effect of sequence length on accuracy of classification,16S rRNA genes of various lengths were created by trimming the full length sequences.Sequences spanning various hypervariable regions were selected to simulate the amplicons that would be obtained using possible primer pairs.The sequences were compared with full length 16S rRNA genes for accuracy in taxonomic classification using online software at the Ribosomal Database Project (RDP).The universality of the primer set was evaluated using the RDP 16S rRNA database which is comprised of 433 306 16S rRNA genes,represented by 36 phyla.RESULTS:Truncation to 100 nucleotides(nt)downstream from the position corresponding to base 28 in the Escherichia coli 16S rRNA gene caused misclassification of 87(39.7%)of the 219 sequences,compared with misclassification of only 29(13.2%)sequences with truncation to 350 nt.Among 350-nt sequence reads within various regions of the 16S rRNA gene,the reverse read of an amplicon generated using the 343F/798R primers had the least(8.2%)effect on classification.In comparison,truncation to 900 nt mimicking single pass Sanger reads misclassified 5.0%of the 219 sequences.The 343F/798R amplicon accurately assigned 91.8%of the 219 sequences at the species level.Weighted by abundance of the species in the esophageal dataset,the 343F/798R amplicon yielded similar classification accuracy without a significant loss in species coverage(92%).Modification of the 343F/798R primers to 347F/803R increased their universality among foregut species.Assuming that a typicalpolymerase chain reaction can tolerate 2 mismatches between a primer and a template,the modified 347F and 803R primers should be able to anneal 98%and 99.6%of all 16S rRNA genes in the RDP database.CONCLUSION:347F/803R is the most suitable pair of primers for classification of foregut 16S rRNA genes but also possess universality suitable for analyses of other complex microbiomes. | Carlos W Nossa William E Oberdorf Jφrn A Aas Bruce J Paster Todd Z DeSantis Eoin L Brodie Daniel Malamud Michael A Poles Zhiheng Pei | 2010 | World Journal of Gastroenterology2010，16，33： | 16 |
| 5 | Kinetic adsorption of application of carbon nanotubes for Pb(Ⅱ) removal from aqueous solution显示文摘The capability of carbon nanotubes (CNTs) to adsorb lead (Pb) in aqueous solution was investigated. Batch mode adsorption experiment was conducted to determine the effects of pH, agitation speed, CNTs dosage and contact time. The removal of Pb(Ⅱ) reached maximum value 85% or 83% at pH 5 or 40 mg/L of CNTs, respectively. Higher correlation coeffcients from Langmuir isotherm model indicates the strong adsorptions of Pb(Ⅱ) on the surface of CNTs (adsorption capacity Xm = 102.04 mg/g). The results indicates that the highest percentage removal of Pb (96.03%) can be achieved at pH 5, 40 mg/L of CNTs, contact time 80 min, and agitation speed 50 r/min. | Nassereldeen A Kabbashi Muataz A Atieh Abdullah Al-Mamun Mohamed E S Mirghami MD Z Alam Noorahayu Yahya | 2009 | Journal of Environmental Sciences2009，21，4： | 15 |
| 6 | A study of pulmonary embolism after abdominal surgery in patients undergoing prophylaxis显示文摘AIM:To determine risk factors for pulmonary embolism and estimate effects and benefits of prophylaxis.METHODS:We included 78 patients who died subsequently to a pulmonary embolism after major abdomi nal surgery from 1985 to 2003.A first,retrospective analysis involved 41 patients who underwent elective surgery between 1985 and 1990 without receiving any prophylaxis.In the prospectively evaluated subgroup,37 patients undergoing major surgery between 1991 and 2003 were enrolled:all of them had received a prophylaxis consisting in low-molecular weight heparin,given subcutaneously at a dose of 2850 IU AXa/0.3 mL(body weight < 50 kg) or 5700 IU AXa/0.6 mL(body weight ≥ 50 kg).RESULTS:A higher incidence of thromboembolism(43.9% and 46.34% in the two groups,respectively) was found in older patients(> 60 years).The incidence of pulmonary embolism after major abdominal surgery in patients who had received the prophylaxis was signifi cantly lower compared to the subjects with the same condition who had not received any prophylaxis(P < 0.001,OR = 2.825;95% CI,1.811-4.408).Furthermore,the incidence of pulmonary embolism after colorectal cancer surgery was signifi cantly higher compared to incidence of pulmonary embolism after other abdominal surgical procedures.Finally,the incidence of pulmonary embolism after colorectal cancer surgery among the patients who had received the prophylaxis(11/4316,0.26%) was significantly lower compared to subjects undergoing a surgical procedure for the same indication but without prophylaxis(10/1562,0.64%)(P < 0.05,OR = 2.522;95% CI,1.069-5.949).CONCLUSION:Prophylaxis with low molecular weight heparin is highly recommended during the preoperative period in patients with diagnosis of colorectal cancer due to high risk of pulmonary embolism after elective surgery. | Mirko D Kerkez Dorde M ulafi Dragana D Mija Vitomir I Rankovi Nebja S Leki Dejan Z Stefanovi | 2009 | World Journal of Gastroenterology2009，15，3： | 14 |

| 16 | Endoscopic submucosal dissection training with pig models in a Western country显示文摘AIM:To test a strategy for endoscopic submucosal dissection(ESD) training in animal models designed to overcome the initial learning curve.METHODS:ESD was attempted in ex vivo and in vivo pig models.Thirty ESD procedures were attempted in the esophagus(n=9) or the stomach(n=21).The ex vivo model was used until initial competence was achieved.In the in vivo model,several ESD procedures were performed in up to 3 sessions.The following variables were analyzed:specimen size,complete and en bloc resection rate,time for circumferential incision,time for submucosal dissection,total ESD duration,and complications.RESULTS:Complete resection was achieved in 28 cases(en bloc 27);2 could not be completed(one perforation,one technical diff iculty).The mean ± SD time for circumferential incision was 36.2±16.8 min(range:8-87 min),and the mean±SD time for submucosal dissection was 45.1±35.7 min(range:9-196 min).The mean±SD size of the resected specimens was 45.2±17.8 mm.The mean±SD total resection time was signif icantly increased for the gastric cases performed in the f irst half of the study(n=13) than in the second half(n=8)(98.9±62.4 min vs 61.7±17.6 min,P=0.04),although the specimen size did not differ.CONCLUSION:Training in animal models could help endoscopists overcome the learning curve before starting ESD in humans. | Adolfo Parra-Blanco María Rosa Arnau David Nicolás-Pérez Antonio Z Gimeno-García Nicolás González Juan A Díaz-Acosta Alejandro Jiménez Enrique Quintero | 2010 | World Journal of Gastroenterology2010，16，23： | 9 |
| 17 | Malignant schwannoma of the pancreas involving transversal colon treated with en-bloc resection显示文摘Pancreatic schwannoma is a very uncommon tumor of the pancreas,with only 27 cases reported.Most pancreatic schwannomas are benign,with only four malignant tumors reported.We describe a case of giant malignant schwannoma of the pancreatic body and tail,which involved the transverse colon.The tumor was treated successfully with en bloc distal splenopancreatectomy and colon resection.This is believed to be the first reported radical operation for malignant schwannoma of the pancreatic body,with infiltration of the transverse colon,with excellent longterm results.The patient is alive and well 28 mo after the operation.The authors conclude that pancreatic schwannomas should be considered in the differential diagnosis of cystic neoplasms of the pancreas,although the diagnosis can only be confirmed by microscopic examination.In the case of the benign tumors,local excision is adequate,but in the case of malignant schwannoma,oncological standards must be fulfilled. | Miroslav P Stojanovic Milan Radojkovic Ljiljana M Jeremic Aleksandar V Zlatic Goran Z Stanojevic Milan A Jovanovic Milos S Kostov Vuka P Katic | 2010 | World Journal of Gastroenterology2010，16，1： | 8 |
| 18 | Updated Kimura-Takemoto classification of atrophic gastritis显示文摘BACKGROUND The Updated Sydney system for visual evaluation of gastric mucosal atrophy viaendoscopic observation is subject to sampling error and interobserver variability.The Kimura-Takemoto classification system was developed to overcome theselimitations.AIMTo compare the morphological classification of atrophic gastritis between theKimura-Takemoto system and the Updated Sydney system.METHODSA total of 169 patients with atrophic gastritis were selected according to diagnosisby the visual endoscopic Kimura-Takemoto method. Following the UpdatedKimura-Takemoto classification system, one antrum biopsy and five gastriccorpus biopsies were taken according to the visual stages of the Kimura-Takemoto system. The Updated Kimura-Takemoto classification system was thenapplied to each and showed 165 to have histological mucosal atrophy;theremaining 4 patients had no histological evidence of atrophy in any biopsy. The Updated Kimura-Takemoto classification was verified as a referencemorphological method and applied for the diagnosis of atrophic gastritis. Addingone more biopsy from the antrum to the six biopsies according to the Updated Kimura-Takemoto classification, constitutes the updated combined Kimura-Takemoto classification and Sydney system.RESULTSThe sensitivity for degree of mucosal atrophy assessed by the Updated Sydneysystem was 25% for mild, 36% for moderate, and 42% for severe, when comparedwith the Updated Kimura-Takemoto classification of atrophic gastritis formorphological diagnosis. Four types of multifocal atrophic gastritis wereidentified: sequential uniform (type 1;in 28%), sequential non-uniform (type 2;in7%), diffuse uniform (type 3;in 23%), diffuse non-uniform (type 4;in 24%), and'alternating atrophic – non-atrophic' (type 5;in 18%). The pattern of the spread ofatrophy, sequentially from the antrum to the cardiac segment of the stomach,which was described by the Updated Kimura-Takemoto system, washistologically confirmed in 82% of cases evaluated.CONCLUSIONThe Updated Sydney system is significantly inferior to the Updated Kimura-Takemoto classification for morphological verification of atrophic gastritis. | Sergey M Kotelevets Sergey A Chekh Sergey Z Chukov | 2021 | World Journal of Clinical Cases2021，9，13： | 8 |
| 19 | Hepatitis B genotypes: Relation to clinical outcome in patients with chronic hepatitis B in Saudi Arabia显示文摘AIM: To identify the most common hepatitis B virus (HBV) genotype in Saudi Arabia, and correlate the prevailing genotypes with the clinical outcome of patients. METHODS: Patients were consecutively recruited from the hepatology clinics of two tertiary care referral cen- ters. Patients were categorized into 4 different groups: group 1, patients with hepatitis B and normal liver en- zymes; group 2, patients with hepatitis B and abnormal liver enzymes but without cirrhosis; group 3, patients with hepatitis B and liver cirrhosis; group 4, patients with hepatitis B and hepatocellular carcinoma. All patients had a positive hepatitis B surface antigen (HBsAg). Ge- notyping of HBV was performed by nested PCR-mediated amplification of the target sequence and hybridization with sequence-specific oligonucleotides. RESULTS: Seventy patients were enrolled in this study. They were predominantly male (72.9%) in their mid- forty’s (mean age 47 years). Forty-nine (70%) patients were hepatitis B envelope antigen (HBeAg) negative. The majority of patients (64%) acquired HBV through unknown risk factors. Hepatitis B genotyping revealed that 57 patients (81.4%) were genotype D, 1 patient (1.4%) had genotype A, 1 patient (1.4%) had geno- type C, and 4 patients (5.7%) had genotype E, while 7 patients (10%) had mixed genotype (4 patients ADG, 1 patient DE, 1 patient DF, and 1 patient ADFG). Based on univariate analysis of genotype D patients, significant predictors of advanced liver disease were age, gender, aspartate transaminase, alanine transaminase, albumin,bilirubin, and alkaline phosphatase (all P < 0.001). In multivariate analysis decreased hemoglobin (r = -0.05; 95% CI: -0.08 to -0.03; P = 0.001) and albumin levels (r = -0.004; 95% CI: -0.007 to -0.001; P = 0.002) were highly significant predictors of advanced liver disease. In patients with HBV genotype D, HBeAg negativity was found to increase across advancing stages of liver dis- ease (P = 0.024). CONCLUSION: This study highlights that the vast ma- jority of Saudi patients with chronic hepatitis B have genotype D. No correlation could be observed between the different genotypes and epidemiological or clinical factors. The relationship between genotype D and HBeAg status in terms of disease severity needs to be further elucidated in larger longitudinal studies. | Ayman A Abdo Badr M Al-Jarallah Faisal M Sanai Ahmad S Hersi Khalid Al-Swat Nahla A Azzam Manal Al-Dukhayil Amira Al-Maarik Faleh Z Al-Faleh | 2006 | World Journal of Gastroenterology2006，12，43： | 7 |
