Modelo teórico para potenciar el emprendimiento innovador en los estudiantes de pregrado de las universidades de Manizales
La presente investigación propone un modelo teórico que tiene como fin principal generar un cambio estratégico en el modo de actuación frente al emprendimiento universitario de Manizales. La necesidad de potenciar el emprendimiento innovador desde la base de los estudiantes de pregrado, permite concluir sobre la pertinencia de la propuesta no solo por el vacío existente, sino por la disposición de la ciudad en convertirse en un ecosistema de emprendimiento donde las IES están llamadas a ser protagonistas. El modelo propuesto tiene implícito la sencillez de su aplicación, que solo requiere la apropiación de los conceptos en su metodología por parte de la alta dirección y su compromiso con la implementación dentro de un proceso sistémico en el tiempo, generando un cultura emprendedora a todo nivel y en especial, en los estudiantes. Las entrevistas con informantes claves y expertos, así como la revisión documental de las experiencias y modelos existentes, permitieron validar el modelo propuesto, que no pretende integrar lo encontrado, sino presentar una nueva forma de generar y gestionar el emprendimiento desde la universidad, dando prioridad a la población estudiantil que busca en la universidad su preparación para enfrentarse a un mundo real y contribuir así al crecimiento y desarrollo económico y social del país.This research proposes a theoretical model that has a principal objective to generate a strategic change in the mode of action concerning the university entrepreneurship Manizales. The need to promote innovative entrepreneurship from the base of undergraduates lets to conclude on the relevance of the proposal, not only by the gap, but by the willingness of the city to become an entrepreneurial ecosystem where the IES are called to be protagonists. The model is implicit simplicity of its implementation, which only requires the appropriation of concepts in its methodology by senior management and their commitment to the implementation within a systemic process in time, creating a culture of entrepreneurship at all levels and especially the students. Interviews with key informants and experts as well as the literature review of experiences and existing models, helped to validate the proposed model does not incorporate the findings, but to present a new way to create and manage the venture since college, prioritizing its student population seeks college preparation to face the real world and contribute to the growth and economic and social development of the country
Valores de referencia basados en el contexto genético de la actividad enzimática de la colinesterasa en una población colombiana: un paso hacia el diagnóstico personalizado
Introduction: The determination of cholinesterase (ChE) activity has been commonly applied in the biomonitoring of exposure to organophosphate and carbamate pesticides. However, ChE activity is influenced by genetic factors. Integrating genotype and phenotype information in clinical laboratory tests would increase the accuracy of the reference values in well-defined populations.Objective: To establish genetic-based reference values for acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) activity in a Colombian population.Materials and methods: A total of 397 healthy adults from Bucaramanga were included in the study. AChE and BChE activities were measured in blood samples by potentiometry and spectrophotometry, respectively. Genotyping for ACHE rs17880573 and BCHE rs1803274 was performed using the TaqMan allelic discrimination assay. The statistical analyses to obtain the reference values were performed with the MedCalc® software.Results: Allele frequencies were 10.58% for rs17880573 A and 8.82% for rs1803274 A. People with genotypes rs1803274 AA and AG showed a reduction of 20.69% and 10.92% respectively in mean BChE activity compared to people with genotype GG. No significant differences were identified in AChE activity between rs17880573 alleles or genotypes. In the overall sample, the corresponding reference values were as follows: for AChE activity, 0.62–0.98 ΔpH/h and for BChE activity, 4796.3–10321.1 U/L for people carrying the allele rs1803274A and 5768.2–11180.4 U/L for people carrying the genotype rs1803274 GG.Conclusion: We strongly recommend using these genetic-based reference values for ChE enzymes in our well-defined population in daily clinical practice.Introducción. La determinación de la actividad enzimática de la colinesterasa se utiliza comúnmente en la vigilancia biológica de la exposición a pesticidas organofosforados y carbamatos. Sin embargo, los factores genéticos afectan la actividad de la colinesterasa, por lo que la integración de la información sobre genotipos y fenotipos en las pruebas de laboratorio clínico, incrementaría la precisión de los valores de referencia.Objetivo. Establecer los valores de referencia basados en el contexto genético para la actividad enzimática de la acetilcolinesterasa (AChE) y la butirilcolinesterasa (BChE), en una población colombiana.Materiales y métodos. Se incluyeron 397 adultos sanos. La actividad de la acetilcolinesterasa y la de la butirilcolinesterasa, se determinaron en muestras de sangre por potenciometría y espectrofotometría, respectivamente. Los genotipos de los ACHE rs17880573 y BCHE rs1803274 se obtuvieron mediante el ensayo TaqMan y los valores de referencia se estimaron con el programa MedCalc®.Resultados. La frecuencia alélica fue de 10,58 % para rs17880573 A y de 8,82 % para rs1803274 A. Las personas con los genotipos rs1803274 AA y AG, mostraron una reducción en el promedio de la actividad de la butirilcolinesterasa de 20,69 % y de 10,92 %, respectivamente, comparados con aquellas con el genotipo GG. No se encontraron diferencias significativas en la actividad de la acetilcolinesterasa con respecto a los alelos y genotipos del rs17880573. Los valores de referencia determinados para esta población fueron de 0,62-0,98 ΔpH/h para acetilcolinesterasa y de 4796,3-10321,1 U/L para butirilcolinesterasa, en las personas portadoras del alelo rs1803274 A, y de 5768,2–11180,4 U/L, en las portadoras del genotipo rs1803274 GG.Conclusión. Se recomienda el uso de estos valores de referencia basados en el contexto genético para las colinesterasas, en la práctica clínica diaria en esta población

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)
Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters.
Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs).
Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001).
Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017
Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning
XVI International Congress of Control Electronics and Telecommunications: "Techno-scientific considerations for a post-pandemic world intensive in knowledge, innovation and sustainable local development"
Este título, sugestivo por los impactos durante la situación de la Covid 19 en el mundo, y que en Colombia lastimosamente han sido muy críticos, permiten asumir la obligada superación de tensiones sociales, políticas, y económicas; pero sobre todo científicas y tecnológicas.
Inicialmente, esto supone la existencia de una capacidad de la sociedad colombiana por recuperar su estado inicial después de que haya cesado la perturbación a la que fue sometida por la catastrófica pandemia, y superar ese anterior estado de cosas ya que se encontraban -y aún se encuentran- muchos problemas locales mal resueltos, medianamente resueltos, y muchos sin resolver: es decir, habrá que rediseñar y fortalecer una probada resiliencia social existente - producto del prolongado conflicto social colombiano superado parcialmente por un proceso de paz exitoso - desde la tecnociencia local; como lo indicaba Markus Brunnermeier - economista alemán y catedrático de economía de la Universidad de Princeton- en su libro The Resilient Society…La cuestión no es preveerlo todo sino poder reaccionar…aprender a recuperarse rápido.This title, suggestive of the impacts during the Covid 19 situation in the world, and which have unfortunately been very critical in Colombia, allows us to assume the obligatory overcoming of social, political, and economic tensions; but above all scientific and technological.
Initially, this supposes the existence of a capacity of Colombian society to recover its initial state after the disturbance to which it was subjected by the catastrophic pandemic has ceased, and to overcome that previous state of affairs since it was found -and still is find - many local problems poorly resolved, moderately resolved, and many unresolved: that is, an existing social resilience test will have to be redesigned and strengthened - product of the prolonged Colombian social conflict partially overcome by a successful peace process - from local technoscience; As Markus Brunnermeier - German economist and professor of economics at Princeton University - indicates in his book The Resilient Society...The question is not to foresee everything but to be able to react...learn to recover quickly.Bogot
Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions
Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p < 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics
Genomic investigations of unexplained acute hepatitis in children
Since its first identification in Scotland, over 1,000 cases of unexplained paediatric hepatitis in children have been reported worldwide, including 278 cases in the UK1. Here we report an investigation of 38 cases, 66 age-matched immunocompetent controls and 21 immunocompromised comparator participants, using a combination of genomic, transcriptomic, proteomic and immunohistochemical methods. We detected high levels of adeno-associated virus 2 (AAV2) DNA in the liver, blood, plasma or stool from 27 of 28 cases. We found low levels of adenovirus (HAdV) and human herpesvirus 6B (HHV-6B) in 23 of 31 and 16 of 23, respectively, of the cases tested. By contrast, AAV2 was infrequently detected and at low titre in the blood or the liver from control children with HAdV, even when profoundly immunosuppressed. AAV2, HAdV and HHV-6 phylogeny excluded the emergence of novel strains in cases. Histological analyses of explanted livers showed enrichment for T cells and B lineage cells. Proteomic comparison of liver tissue from cases and healthy controls identified increased expression of HLA class 2, immunoglobulin variable regions and complement proteins. HAdV and AAV2 proteins were not detected in the livers. Instead, we identified AAV2 DNA complexes reflecting both HAdV-mediated and HHV-6B-mediated replication. We hypothesize that high levels of abnormal AAV2 replication products aided by HAdV and, in severe cases, HHV-6B may have triggered immune-mediated hepatic disease in genetically and immunologically predisposed children
