| 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 |

| 3 | Incretins and selective renal sodium-glucose co-transporter 2 inhibitors in hypertension and coronary heart disease显示文摘Hyperglycemia is associated with an increased risk of cardiovascular disease,and the consequences ofintensive therapy may depend on the mechanism of the anti-diabetic agent(s)used to achieve a tight control.In animal models,stable analogues of glucagon-like peptide-1(GLP-1)were able to reduce body weight and blood pressure and also had favorable effects on ischemia following coronary reperfusion.In a similar way,dipeptidyl peptidase IV(DPPIV)showed to have favorable effects in animal models of ischemia/reperfusion.This could be due to the fact that DPPIV inhibitors were able to prevent the breakdown of GLP-1 and glucose-dependent insulinotropic polypeptide,but they also decreased the degradation of several vasoactive peptides.Preclinical data for GLP-1,its derivatives and inhibitors of the DPPIV enzyme degradation suggests that these agents may be able to,besides controlling glycaemia,induce cardio-protective and vasodilator effects.Notwithstanding the many favorable cardiovascular effects of GLP-1/incretins reported in different studies,many questions remain unanswered due the limited number of studies in human beings that aim to examine the effects of GLP-1 on cardiovascular endpoints.For this reason,long-term trials searching for positive cardiovascular effects are now in process,such as the CAROLINA and CARMELINA trials,which are supported by small pilot studies performed in humans(and many more animal studies)with incretin-based therapies.On the other hand,selective renal sodium-glucose co-transporter 2 inhibitors were also evaluated in the prevention of cardiovascular outcomes in type 2 diabetes.However,it is quite early to draw conclusions,since data on cardiovascular outcomes and cardiovascular death are limited and long-term studies are still ongoing.In this review,we will analyze the mechanisms underlying the cardiovascular effects of incretins and,at the same time,we will present a critical position about the real value of these compounds in the cardiovascular system and its protection. | Ramiro A Sanchez Hugo Sanabria Cecilia de los Santos Agustin J Ramirez | 2015 | World Journal of Diabetes2015，6，11： | 5 |
| 4 | Analysis of the postoperative hemostatic profile of colorectal cancer patients subjected to liver metastasis resection surgery显示文摘BACKGROUND Liver resection surgery has advanced greatly in recent years,and the adoption of fasttrack programs has yielded good results.Combination anesthesia (general anesthesia associated to epidural analgesia) is an anesthetic-analgesic strategy commonly used for the perioperative management of patients undergoing surgery of this kind,though there is controversy regarding the coagulation alterations it may cause and which can favor the development of spinal hematomas.AIM To study the postoperative course of liver resection surgery,an analysis was made of the outcomes of liver resection surgery due to colorectal cancer metastases in our centre in terms of morbiditymortality and hospital stay according to the anesthetic technique used (general vs combination anesthesia).METHODS A prospective study was made of 61 colorectal cancer patients undergoing surgery due to liver metastases under general and combination anesthesia between January 2014 and October 2015.The patient characteristics,intraoperative variables,postoperative complications,evolution of hemostatic parameters,and stay in intensive care and in hospital were analyzed.RESULTS A total of 61 patients were included in two homogeneous groups: general anesthesia (n = 30) and combination anesthesia (general anesthesia associated to epidural analgesia)(n = 31).All patients had normal coagulation values before surgery.The international normalized ratio (INR) in both the general and combination anesthesia groups reached maximum values at 2448 h (mean 1.37 and 1.45 vs 1.39 and 1.41,respectively),followed by a gradual decrease.There was less intraoperative bleeding in the combination anesthesia group (769 mL) than in the general anesthesia group (1200 mL)(P < 0.05).Of the 61 patients,38.8% in the general anesthesia group experienced some respiratory complication vs 6.6% in the combination anesthesia group (P < 0.001).The time to gastrointestinal tolerance was significantly correlated to the type of anesthesia,though not so the stay in critical care or the time to hospital discharge.CONCLUSION Epidural analgesia in liver resection surgery was seen to be safe,with good results in terms of pain control and respiratory complications,and with no associated increase in complications secondary to altered hemostasis. | Guillermo Perez Navarro Ana Maria Pascual Bellosta Sonia María Ortega Lucea Mario Serradilla Martín Jose Manuel Ramirez Rodriguez Javier Martinez Ubieto | 2019 | World Journal of Clinical Cases2019，7，17： | 4 |

| 6 | A techno-economic and life cycle assessment for the production of green methanol from CO_(2): catalyst and process bottlenecks显示文摘The success of catalytic schemes for the large-scale valorization of CO_(2) does not only depend on the development of active,selective and stable catalytic materials but also on the overall process design.Here we present a multidisciplinary study(from catalyst to plant and techno-economic/lifecycle analysis)for the production of green methanol from renewable H2 and CO_(2).We combine an in-depth kinetic analysis of one of the most promising recently reported methanol-synthesis catalysts(InCo)with a thorough process simulation and techno-economic assessment.We then perform a life cycle assessment of the simulated process to gauge the real environmental impact of green methanol production from CO_(2).Our results indicate that up to 1.75 ton of CO_(2) can be abated per ton of produced methanol only if renewable energy is used to run the process,while the sensitivity analysis suggest that either rock-bottom H2 prices(1.5$kg1)or severe CO_(2) taxation(300$per ton)are needed for a profitable methanol plant.Besides,we herein highlight and analyze some critical bottlenecks of the process.Especial attention has been paid to the contribution of H2 to the overall plant costs,CH4 trace formation,and purity and costs of raw gases.In addition to providing important information for policy makers and industrialists,directions for catalyst(and therefore process)improvements are outlined. | Tomas Cordero-Lanzac Adrian Ramirez Alberto Navajas Lieven Gevers Sirio Brunialti Luis MGandía Andrés T.Aguayo S.Mani Sarathy Jorge Gascon | 2022 | Journal of Energy Chemistry2022，31，5： | 3 |
| 7 | Quality monitoring in colonoscopy: Time to act显示文摘Colonoscopy is the gold standard test for colorectal cancer screening. The primary advantage of colonoscopy as opposed to other screening modalities is the ability to provide therapy by removal of precancerous lesions at the time of detection. However, colonoscopy may miss clinically important neoplastic polyps. The value of colonoscopy in reducing incidence of colorectal cancer is dependent on many factors including, the patient, provider, and facility level. A high quality examination includes adequate bowel preparation, optimal colonoscopy technique, meticulous inspection during withdrawal, identification of subtle flat lesions, and complete polypectomy. Considerable variation among institutions and endoscopists has been reported in the literature. In attempt to diminish this disparity, various approaches have been advocated to improve the quality of colonoscopy. The overall impact of these interventions is not yet well defined. Implementing optimal education and training and subsequently analyzing the impact of these endeavors in improvement of quality will be essential to augment the utility of colonoscopy for the prevention of colorectal cancer. | Mary A Atia Francisco C Ramirez Suryakanth R Gurudu | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，4： | 3 |

| 10 | Polyp detection rates using magnification with narrow band imaging and white light显示文摘AIM: To compare the yield of adenomas between narrow band imaging and white light when using high definition/magnification. METHODS: This prospective, non-randomized comparative study was performed at the endoscopy unit of veteran affairs medical center in Phoenix, Arizona. Consecutive patients undergoing first average risk colorectal cancer screening colonoscopy were selected. Two experienced gastroenterologists performed all the procedures that were blinded to each other's findings. Demographic details were recorded. Data are presented as mean ± SEM. Proportional data were compared using the χ2 test and means were compared using the Student's t test. Tandem colonoscopy was performed in a sequential and segmental fashion using one of 3 strategies: white light followed by narrow band imaging [Group A: white light(WL) → narrow band imaging(NBI)]; narrow band imaging followed by white light(Group B: NBI → WL) and, white light followed by white light(Group C: WL → WL). Detection rate of missed polyps and adenomas were evaluated in all three groups. RESULTS: Three hundred patients were studied(100 in each Group). Although the total time for the colonoscopy was similar in the 3 groups(23.8 ± 0.7, 22.2 ± 0.5 and 24.1 ± 0.7 min for Groups A, B and C, respectively), it reached statistical significance between Groups B and C(P < 0.05). The cecal intubation time in Groups B and C was longer than for Group A(6.5 ± 0.4 min and 6.5 ± 0.4 min vs 4.9 ± 0.3 min; P < 0.05). The withdrawal time for Groups A and C was longer than Group B(18.9 ± 0.7 min and 17.6 ± 0.6min vs 15.7 ± 0.4 min; P < 0.05). Overall miss rate for polyps and adenomas detected in three groups during the second look was 18% and 17%, respectively(P = NS). Detection rate for polyps and adenomas after first look with white light was similar irrespective of the light used during the second look(WL → WL: 13.7% for polyps, 12.6% for adenomas; WL → NBI: 14.2% for polyps, 11.3% for adenomas). Miss rate of polyps and adenomas however was significantly higher when NBI was used first(29.3% and 30.3%, respectively; P < 0.05). Most missed adenomas were ≤ 5 mm in size. There was only one advanced neoplasia(defined by size only) missed during the first look. CONCLUSION: Our data suggest that the tandem nature of the procedure rather than the optical techniques was associated with the detection of additional polyps' and adenomas. | Nooman Gilani Sally Stipho James D Panetta Sorin Petre Michele A Young Francisco C Ramirez | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 2 |
