Morphine in Plasma and Cerebrospinal Fluid of Patients Addicted to Opiates Undergoing Surgery: High-performance Liquid Chromatography Method

Background: The prevalence of opium addiction among Iranians is considerable. Since endogenous opioid systems may be altered as a consequence of addiction, it is very important to determine the plasma and cerebrospinal fluid (CSF) levels of morphine in Iranian patients addicted to opiates who will undergo surgery.Methods: We obtained CSF and plasma samples from 50 volunteers with an established opioid addiction pattern. Samples were analyzed using high-performance liquid chromatography (HPLC). Additionally, frequency of nausea and vomiting, baseline heart rate (BHR), and systolic blood pressure (SBP) were recorded within the surgery and postoperatively during a 10-min interval.Findings: 84% of participants were men with a median age of 39.08 years. Mean score of body mass index (BMI) was 23.30 and most of the participants (46%) used opium in its traditional inhaled form. A higher concentration of morphine in blood was found in comparison with CSF (P < 0.001) in relation to the way of use. However, no statistically significant differences were found in relation to the type of addictive substance. No other association was found between the levels of morphine and the clinical characteristics of the patients. Moreover, results revealed no difference between hemodynamic-related data with blood and CSF level in opium-dependent patients.Conclusion: Quantification of plasma and CSF morphine, both immediately before initiation of surgery and subsequently on recovery room, showed that although clinical efficacy of systemic morphine was poor in addicted patients, it had no effect on patients’ hemodynamic variable and following complications after surgery

Green economy metrics as a promoter of sustainable development in universities. Case study: El Bosque University

The exchange that occurs in universities when they participate in international rankings is an important space to share and grow in the academic production of teachers and in the training of students. At the beginning, the sustainable social responsibility system was adhered only to the industry due to the increase in large-scale production; however, the academy has taken a voice and vote on this climate phenomenon. This is why projects aimed at sustainability have been proposed in universities that aim at a green economy. Likewise, the UI Green Metric Rankings allows higher education institutions worldwide to measure their sustainable actions in different categories on a voluntary basis.For this reason, this article presents the best practices of the University El Bosque against the different indicators that the UI Green Metric measures, such as infrastructure, energy and climate change, waste, water, transport and education. Consequently, the concept of sustainability has become a vital element for the development of programs that involve the institution in internationalization through the global recognition generated by being participants and being able to be in the range of green universities.As a conclusion of this exchange, Based on responsible production methods with the natural and social environment or Clean Modalities, a production cycle is proposed that opens the possibility of integrating with other related production systems that receive their waste as raw materials in a network, this is Symbiotic Cycle. To arrive at the approach of a symbiotic disposal of waste as inputs with other production systems in such a way as to consolidate a set of sustainable organizations that collaborate with each other and that continuously recover the value to increase efficiency.Keyword: sustainability, green economy, sustainable developmen

Acciones y retos para una transformación verde y sustentable del Campus Universitario: Actions and Challenges for Green and Sustainable Campus Transformation

Con motivo del cumplimiento de los 10 años del ranking internacional de Universidades Verdes y en nuestra condi-ción de coordinadores nacionales de la red en Colombia, a continuación incluimos este reporte de lo que ha sido el trasegar de la red y de la Universidad el Bosque. El IU GreenMetric se crea en 2010 por parte de la Universidad de Indonesia. Para este primer año participaron 95 Universidades a nivel mundial, posicionándose en primer lugar la Universidad de California Berkeley. Por su parte Colombia tuvo como participante a la Universidad de Los Andes, ocupando el puesto 94, con un puntaje de 3056,06.La Universidad El Bosque realizo su primera aparición en el año 2014, ocupando el puesto 267 de los 361 participantes y dentro de los participantes colombianos se ubicó en la posición número 9 con un puntaje total obtenido de 4304. A partir del año mencionado nuestra institución ha realizado la inscripción a este programa con el fin de fomentar mejoras en sus procesos y en los diferentes aspectos que se evalúa en el “IU GreenMetric”.En este contexto para el año 2017 la Universidad El Bosque lideró el primer workshop nacional. En el presente documento se expone el consolidando de los temas tratados durante el evento con su respectiva asistencia. Así mismo, se presentará el informe de la participación de la institución en el UI GreenMetric Ranking; para el cual, los resultados reportados por la Universidad de Indonesia establecen que la Universidad El Bosque ha ocupado el puesto 242 a nivel internacional, y a nivel nacional se calificó en el puesto 12

Redundancy Is Not Necessarily Detrimental in Classification Problems

In feature selection, redundancy is one of the major concerns since the removal of redun dancy in data is connected with dimensionality reduction. Despite the evidence of such a connection, few works present theoretical studies regarding redundancy. In this work, we analyze the effect of redundant features on the performance of classification models. We can summarize the contribution of this work as follows: (i) develop a theoretical framework to analyze feature construction and selection, (ii) show that certain properly defined features are redundant but make the data linearly separable, and (iii) propose a formal criterion to validate feature construction methods. The results of experiments suggest that a large number of redundant features can reduce the classification error. The results imply that it is not enough to analyze features solely using criteria that measure the amount of information provided by such features.CONACYT - Consejo Nacional de Ciencia y TecnologíaPROCIENCI

Epidemiology of intra-abdominal infection and sepsis in critically ill patients: “AbSeS”, a multinational observational cohort study and ESICM Trials Group Project

Purpose: To describe the epidemiology of intra-abdominal infection in an international cohort of ICU patients according to a new system that classifies cases according to setting of infection acquisition (community-acquired, early onset hospital-acquired, and late-onset hospital-acquired), anatomical disruption (absent or present with localized or diffuse peritonitis), and severity of disease expression (infection, sepsis, and septic shock). Methods: We performed a multicenter (n = 309), observational, epidemiological study including adult ICU patients diagnosed with intra-abdominal infection. Risk factors for mortality were assessed by logistic regression analysis. Results: The cohort included 2621 patients. Setting of infection acquisition was community-acquired in 31.6%, early onset hospital-acquired in 25%, and late-onset hospital-acquired in 43.4% of patients. Overall prevalence of antimicrobial resistance was 26.3% and difficult-to-treat resistant Gram-negative bacteria 4.3%, with great variation according to geographic region. No difference in prevalence of antimicrobial resistance was observed according to setting of infection acquisition. Overall mortality was 29.1%. Independent risk factors for mortality included late-onset hospital-acquired infection, diffuse peritonitis, sepsis, septic shock, older age, malnutrition, liver failure, congestive heart failure, antimicrobial resistance (either methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, extended-spectrum beta-lactamase-producing Gram-negative bacteria, or carbapenem-resistant Gram-negative bacteria) and source control failure evidenced by either the need for surgical revision or persistent inflammation. Conclusion: This multinational, heterogeneous cohort of ICU patients with intra-abdominal infection revealed that setting of infection acquisition, anatomical disruption, and severity of disease expression are disease-specific phenotypic characteristics associated with outcome, irrespective of the type of infection. Antimicrobial resistance is equally common in community-acquired as in hospital-acquired infection
