    New multi-target indole and naphthalene derivatives containing the oxadiazolone scaffold as a bioisostere of the melatonin acetamido group have been developed. The novel compounds were characterized at melatonin receptors MT1R and MT2R, quinone reductase 2 (QR2), lipoxygenase-5 (LOX-5), and monoamine oxidases (MAO-A and MAO-B), and also as radical scavengers. We found that selectivity within the oxadiazolone series can be modulated by modifying the side chain functionality and coplanarity with the indole or naphthalene ring. In phenotypic assays, several oxadiazolone-based derivatives induced signalling mediated by the transcription factor NRF2 and promoted the maturation of neural stem-cells into a neuronal phenotype. Activation of NRF2 could be due to the binding of indole derivatives to KEAP1, as deduced from surface plasmon resonance (SPR) experiments. Molecular modelling studies using the crystal structures of QR2 and the KEAP1 Kelch-domain, as well as the recently described X-ray free-electron laser (XFEL) structures of chimeric MT1R and MT2R, provided a rationale for the experimental data and afforded valuable insights for future drug design endeavoursThe authors gratefully acknowledge the following financial supports: Spanish Ministry of Science, Innovation and Universities; Spanish Research Agency; and European Regional Development Funds (grants RTI2018-093955-B-C21 and SAF2015-64948-C2-1-R to M.I.R.-F.; RTI2018-095793-B-I00 to M.G.L., SAF2015-64629-C2- 2-R to F.G.), General Council for Research and Innovation of the Community of Madrid and European Structural Funds (grant B2017/BMD-3827 e NRF24ADCM), Health Institute Carlos III (Miguel Servet II ProgramCP16/00014 and grant PI17/01700 to R.L.).

    Es importante establecer y visibilizar a los estudiantes los beneficios relacionados con la formaciĂłn en investigaciĂłn, dentro de los cuales encontramos el fortalecimiento de las capacidades de liderazgo asĂ­ como el compromiso activo y las experiencias en independencia y colaboraciĂłn. AsĂ­ mismo, la formaciĂłn integral hacia una mayor apreciaciĂłn del valor de la literatura disciplinaria, generando de esta manera habilidades de pensamiento crĂ­tico, indagaciĂłn y anĂĄlisis. AdemĂĄs, esto permite forjar la confianza en sĂ­ mismo para presentar las propias ideas a la comunidad, permitiendo al estudiante la preparaciĂłn de futuras actividades acadĂ©micas, incluidos estudios de posgrado. La investigaciĂłn formativa tiene como propĂłsito la difusiĂłn de la informaciĂłn existente y permitir que el estudiante la integre como conocimientos, considerĂĄndolo como un aprendizaje permanente y necesario. Uno de los principales problemas que debe enfrentar la investigaciĂłn formativa es el nĂșmero de docentes con las capacidades necesarias para generar en el estudiante capacidades investigativas, exigiendo al profesor universitario adoptar una actitud contraria al objeto de enseñanza, generando un carĂĄcter complejo y dinĂĄmico del conocimiento.CONTENTS RETOS DE LA INVESTIGACIÓN EN PREGRADO..................................................5 CHALLENGES OF UNDERGRADUATE RESEARCH.............................................9 German Oved Acevedo Osorio CHAPTER 1 HEALTH AND SPORTS SCIENCES FACTORS ASSOCIATED WITH EXACERBATIONS OR CRISIS EVENTS OF CHRONIC NON COMMUNICABLE DISEASES.........................13 Giovanni GarcĂ­a Castro, Sandra Milena Bedoya Gaviria, Isabela Patiño PulgarĂ­n y Valentina Valencia FlĂłrez ORAL ANTICOAGULATION IN PATIENTS WITH NON-VALVULAR ATRIAL FIBRILLATION IN A UNIVERSITY HOSPITAL IN COLOMBIA.....................................................................................................29 MarĂ­a Leonor Galindo MĂĄrquez, Adrian Giraldo Diaconeasa, Juan DarĂ­o Franco RamĂ­rez y Eduardo RamĂ­rez Vallejo PERFORMANCE IN INITIAL TRAUMAASSESSMENT OF EMERGENCY TEAMS FROM PREHOSPITAL CARE TEAMS..................43 Giovanni GarcĂ­a Castro, Yamileth Estrada Berrio, Manuela Aguirre Torres e Isabella DĂ­az Leal ACADEMIC TRAINING AND WORKING CONDITIONS OF NURSING PROFESSIONALS IN PEREIRA - RISARALDA 2020.....................55 Miguel Ángel GĂłmez Puerta, Laura Isabel Orozco SantamarĂ­a, Alexandra Villa Patiño y Gladys Judith Basto HernĂĄndez EFFECTS OF DYNAMIC TAPE WITH ANTI-VALGUS APPLICATION ON VERTICAL JUMP PERFORMANCE IN PHYSICALLY ACTIVE WOMEN: A CASE STUDY ..........................................73 MarĂ­a Camila Arias Castro, Alejandro GĂłmez Rodas y Ángela MarĂ­a Cifuentes RĂ­os PROPOSAL OF CARE FOR DIAGNOSTIC PREVALENT NURSES IN AN EMERGENCY DEPARTMENT................................................................89 Tatiana Restrepo PĂ©rez, Jessica Viviana RĂ­os Uribe, Anyi Daniela Lemos CĂłrdoba, Anyi Katherine Mapura Benjumea and MĂłnica Margarita BarĂłn Castro FACTORS AND CONCEPTS ASSOCIATED WITH THE INITIATION OF CIGARETTE CONSUMPTION IN UNIVERSITY STUDENTS OF PEREIRA, COLOMBIA ............................................................................... 113 Giovanni GarcĂ­a Castro, Claudia Milena Bernal Parra, Natalia Cardona Arroyave, Brahiam Stiven Moreno Bustamante y Daniela Ospina Sierra CHAPTER 2 ECONOMIC, ADMINISTRATIVE AND ACCOUNTING SCIENCES TECHNICAL-FINANCIAL EVALUATION OF BEAN (PHASEOLUS VULGARIS) VARIETY CARGAMANTO IN THE VILLAGE OF THE MUNICIPALITY OF SIBUNDOY IN THE DEPARTMENT OF PUTUMAYO ................................................................................................ 131 Adriana MarĂ­a Cuervo Rubio, Alejandra Arango Baranza IMPLEMENTATION OF THE NIF IN MICRO-ENTERPRISES OF PEREIRA CITY ............................................................................................ 151 Laura Cortes Correa y Nataly Andrea GutiĂ©rrez STRATEGIC FRAMEWORK FOR SUSTAINABLE PRODUCTION IN COLOMBIA................................................................................................... 163 Paulina Murillo GĂłmez, Manuela RamĂ­rez Osorio, Laura Juliana RodrĂ­guez Henao, Lindy Neth Perea Mosquera, Isabel Redondo RamĂ­rez SUSTAINABLE INNOVATION IN MANUFACTURING INDUSTRY........... 179 Mariana Buitrago Zuleta, Laura Juliana RodrĂ­guez Henao, Lindy Neth Perea Mosquera y Marlen Isabel Redondo RamĂ­rez CHAPTER 3 ARTS, HUMANITIES AND SOCIAL SCIENCES PERSONAL AND FAMILY CHANGES OF UNDERGRADUATE PSYCHOLOGY STUDENTS.

    Get PDF
    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

    Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions

    Get PDF
    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 &lt; 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

    Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
