1Device-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 2017World Journal of Biological Chemistry2017,8,1:23
2Role of IL-10 and TGF-β1 in local immunosuppression in HPV-associated cervical neoplasia显示文摘Cervical cancer is a worldwide disease that constitutes a significant public health problem, especially in developing countries, not only due to its high incidence but also because the most affected population comprises women who belong to marginalized socio-economic classes. Clinical and molecular research has identified immunological impairment in squamous intraepithelial cervical lesions and cervical cancer patients. Human Papillomavirus(HPV) has several mechanisms for avoiding the immune system: it down-regulates the expression of interferon and upregulates interleukin(IL)-10and transforming growth factor(TGF)-β1 to produce a local immunosuppressive environment, which, along with altered tumor surface antigens, forms an immunosuppressive network that inhibits the antitumor immune response. In this review we analyzed the available data on several deregulated cellular immune functions in patients with NIC Ⅰ, NIC Ⅱ and NIC Ⅲ and cervical cancer. The effects of immunosuppressive cytokines on innate immune response, T-cell activation and cellular factors that promote tumor cell proliferation in cervical cancer patients are summarized. We discuss the functional consequences of HPV E2, E6, and E7 protein interactions with IL-10 and TGF-β1 promoters in the induction of these cytokines and postulate its effect on the cellular immune response in squamous intraepithelial cervical lesions and cervical cancer patients. This review provides a comprehensive picture of the immunological functions of IL-10 and TGF-β1 in response to HPV in humans.Kirvis Torres-Poveda Margarita Bahena-Román Claudia Madrid-González Ana I Burguete-García Víctor Hugo Bermúdez-Morales Oscar Peralta-Zaragoza Vicente Madrid-Marina 2014World Journal of Clinical Oncology2014,5,4:21
3Advances in InGaAs/InP single-photon detector systems for quantum communication显示文摘Single-photon detectors(SPDs)are the most sensitive instruments for light detection.In the near-infrared range,SPDs based on III–V compound semiconductor avalanche photodiodes have been extensively used during the past two decades for diverse applications due to their advantages in practicality including small size,low cost and easy operation.In the past decade,the rapid developments and increasing demands in quantum information science have served as key drivers to improve the device performance of single-photon avalanche diodes and to invent new avalanche quenching techniques.This Review aims to introduce the technology advances of InGaAs/InP single-photon detector systems in the telecom wavelengths and the relevant quantum communication applications,and particularly to highlight recent emerging techniques such as high-frequency gating at GHz rates and free-running operation using negative-feedback avalanche diodes.Future perspectives of both the devices and quenching techniques are summarized.Jun Zhang Mark A Itzler Hugo Zbinden Jian-Wei Pan 2015Light(Science & Applications)2015,4,1:21
4Cytokines,cytokine gene polymorphisms and Helicobacter pylori infection:Friend or foe?显示文摘Helicobacter pylori(H.pylori)is a flagellated,spiralshaped,microaerophilic Gram-negative bacillus that colonises the gastric mucosa of more than 50%of the human population.Infection is a risk factor for gastritis,ulcer disease and stomach cancer.Immunity against H.pylori is mainly related to Th1/Th17 skewing,and the activation of regulatory T cells is the main strategy used to limit inflammatory responses,which can result in the pathogen persistence and can lead to chronic gastrointestinal diseases,including cancer.Furthermore,host genetic factors that affect cytokines may determine differences in the susceptibility to many diseases.In this review,we present the cytokine profiles and the main cytokine gene polymorphisms associated with resistance/susceptibility to H.pylori and discuss how such polymorphisms may influence infection/disease outcomes.Camila A Figueiredo Cintia Rodrigues Marques Ryan dos Santos Costa Hugo Bernardino F da Silva Neuza M Alcantara-Neves 2014World Journal of Gastroenterology2014,20,18:11
5Incretins 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 2015World Journal of Diabetes2015,6,11:5

7Interventional treatment of the left subclavian in 2 patients with coronary steal syndrome显示文摘In patients with history of coronary artery disease angina pectoris is usually attributed to the progression of atherosclerotic lesions. However,in patients with previous coronary artery bypass graft operation(CABG) using internal mammary artery grafts,great vessel disease should also be considered. Herein we present two patients with history of CABG whose symptoms were suspicious for coronary ischemia. During cardiac catheterization reverse blood flow was observed from the left artery disease to the left internal mammary artery(LIMA) graft in both cases. After angioplasty and stent implantation of the left subclavian artery antegrade flow was restored in the LIMA grafts and both patients had complete resolution of symptoms.Julia Heid Britta Vogel Arnt Kristen Wanda Kloos Benedikt Kohler Hugo A Katus Grigorios Korosoglou 2017World Journal of Cardiology2017,9,1:3
8Quantitative assessment of myocardial blush grade in patients with coronary artery disease and in cardiac transplant recipients显示文摘Quantitative assessment of myocardial perfusion by myocardial blush grade(MBG) is an angiographic computer-assisted method to assess myocardial tissue-level reperfusion in patients with acute coronary syndromes and microvascular integrity in heart transplant recipients with suspected cardiac allograft vasculopathy. This review describes the ability of quantitative MBG as a simple, fast and cost effective modality for the prompt diagnosis of impaired microvascular integrity during routine cardiac catheterization. Herein, we summarize the existing evidence, its usefulness in the clinical routine, and compare this method to other techniques which can be used for the assessment of myocardial perfusion.Nina Patricia Hofmann Hartmut Dickhaus Hugo A Katus Grigorios Korosoglou 2014World Journal of Cardiology2014,6,10:2

10Influence of different second generation antipsychotics on the QTc interval: A pragmatic study显示文摘AIM To investigate whether differential influence on the QTc interval exists among four second generation antipsychotics(SGAs) in psychosis.METHODS Data were drawn from a pragmatic, randomized headto-head trial of the SGAs risperidone, olanzapine, quetiapine, and ziprasidone in acute admissions patients with psychosis, and with follow-up visits at discharge or maximally 6-9 wk, 3, 6, 12 and 24 mo. Electrocardiograms were recorded on all visits. To mimic clinical shared decision-making, the patients were randomized not to a single drug, but to a sequenceof the SGAs under investigation. The first drug in the sequence defined the randomization group, but the patient and/or clinician could choose an SGA later in the sequence if prior negative experiences with the first one(s) in the sequence had occurred. The study focuses on the time of, and actual use of the SGAs under investigation, that is until treatment discontinuation or change, in order to capture the direct medication effects on the QTc interval. Secondary intention-to-treat(ITT) analyses were also performed. RESULTS A total of 173 patients, with even distribution among the treatment groups, underwent ECG assessments. About 70% were males and 43% had never used antipsychotic drugs before the study. The mean antipsychotic doses in milligrams per day with standard deviations(SD) were 3.4(1.2) for risperidone, 13.9(4.6) for olanzapine, 325.9(185.8) for quetiapine, and 97.2(42.8) for ziprasidone treated groups. The time until discontinuation of the antipsychotic drug used did not differ in a statistically significant way among the groups(Log-Rank test: P = 0.171). The maximum QTc interval recorded during follow-up was 462 ms. Based on linear mixed effects analyses, the QTc interval change per day with standard error was-0.0030(0.0280) for risperidone;-0.0099(0.0108) for olanzapine;-0.0027(0.0170) for quetiapine, and-0.0081(0.0229) for ziprasidone. There were no statistically significant differences among the groups in this regard. LME analyses based on ITT groups(the randomization groups), revealed almost identical slopes with-0.0063(0.0160) for risperidone,-0.0130(0.0126) for olanzapine,-0.0034(0.0168) for quetiapine, and-0.0045(0.0225) for ziprasidone. CONCLUSION None of the SGAs under investigation led to statistically significant QTc prolongation. No statistically significant differences among the SGAs were found.Roy E Olsen Rune A Kroken Sigmund Bj?rhovde Kristina Aanesen Hugo A J?rgensen Else-Marie L?berg Erik Johnsen 2016World Journal of Psychiatry2016,6,4:2
11Effective use of FibroTest to generate decision trees in hepatitis C显示文摘AIM:To assess the usefulness of FibroTest to forecast scores by constructing decision trees in patients with chronic hepatitis C.METHODS:We used the C4.5 classification algorithm to construct decision trees with data from 261 patients with chronic hepatitis C without a liver biopsy.The FibroTest attributes of age,gender,bilirubin,apolipoprotein,haptoglobin,α2 macroglobulin,and γ-glutamyl transpeptidase were used as predictors,and the FibroTest score as the target.For testing,a 10-fold cross validation was used.RESULTS:The overall classification error was 14.9%(accuracy 85.1%).FibroTest's cases with true scores of F0 and F4 were classified with very high accuracy(18/20 for F0,9/9 for F0-1 and 92/96 for F4) and the largest confusion centered on F3.The algorithm produced a set of compound rules out of the ten classification trees and was used to classify the 261 patients.The rules for the classification of patients in F0 and F4 were effective in more than 75% of the cases in which they were tested.CONCLUSION:The recognition of clinical subgroups should help to enhance our ability to assess differences in fibrosis scores in clinical studies and improve our understanding of fibrosis progression.Dana Lau-Corona Luís Alberto Pineda Héctor Hugo Avilés Gabriela Gutiérrez-Reyes Blanca Eugenia Farfan-Labonne Rafael Núez-Nateras Alan Bonder Rosalinda Martínez-García Clara Corona-Lau Marco Antonio Olivera-Martínez Maria Concepción Gutiérrez-Ruiz Guillermo Robles-Díaz David Kershenobich 2009World Journal of Gastroenterology2009,15,21:2
