Management of Entrepreneurship Projects from Project‐Based Learning: Coworking StartUPS Project at Universidad Politécnica Salesiana (Salesian Polytechnic University), Ecuador
In the engineering education field, there is an identified need of innovative learning and teaching methods to improve students’ entrepreneurship competencies in order to make connections between engineering and real society. This chapter addresses a management strategy for entrepreneurship projects in the university framework. It is the result of a cooperative experience from the Research Groups of Salesian Polytechnic University (UPS), the Technical University of Madrid (UPM), and the collaboration of other external entities. The management strategy is applied to undergraduate and postgraduate programs at UPS and has been called Coworking StartUPS Project. The research method is made up of different teaching methodologies—project‐based learning, coworking, case studies—and different activities in and out of the university. The data were collected from students who were enrolled in the Coworking StartUPS Project, along with students and researchers from the three University Branch Campuses in the cities of Cuenca, Quito, and Guayaquil. The Coworking StartUPS Project links teaching & research activities with entrepreneurship are founded in cooperation and interaction, offering multiple possibilities for entrepreneurial skills development in the international context. This preprofessional experience promotes students to integrate the knowledge they have learnt and apply the new knowledge in an entrepreneurship project
Serological evidence of exposure of Bornean wild carnivores to feline-related viruses at the domestic animal-wildlife interface
We conducted an exploratory serological survey to evaluate the exposure of Bornean wild carnivores to several viruses common to domestic felids, at interface areas between protected forest and industrial agriculture in the Kinabatangan floodplain (Sabah, Malaysia). Blood samples, collected from wild carnivores (n = 21) and domestic cats (n = 27), were tested for antibodies against feline coronavirus (FCoV), feline panleukopenia virus (FPLV), feline herpesvirus (FHV) and feline calicivirus (FCV), using commercial enzyme-linked immunosorbent assay (ELISA) test kits. Anti-FCoV antibodies were detected in most species, including one flat-headed cat (Prionailurus planiceps, [1/2]), leopard cats (Prionailurus bengalensis, [2/5]), Malay civets (Viverra tangalunga, [2/11]) and domestic cats (Felis catus, [2/27]). Anti-FCV antibodies were present in all domestic cats and one flat-headed cat, while anti-FPLV antibodies were identified in Sunda clouded leopards (Neofelis diardi, [2/2]), domestic cats [12/27] and Malay civets [2/11]. Anti-FHV antibodies were only detected in domestic cats [2/27]. Our findings indicate pathogen transmission risk between domestic and wild carnivore populations at the domestic animal–wildlife interface, emphasizing the concern for wildlife conservation for several endangered wild carnivores living in the area. Special consideration should be given to species that benefit from their association with humans and have the potential to carry pathogens between forest and plantations (e.g., Malay civets and leopard cats). Risk reduction strategies should be incorporated and supported as part of conservation actions in human-dominated landscapes
Energy metabolism during repeated sets of leg press exercise leading to failure or not
This investigation examined the influence of the number of repetitions per set on power output and muscle metabolism during leg press exercise. Six trained men (age 34±6 yr) randomly performed either 5 sets of 10 repetitions (10REP), or 10 sets of 5 repetitions (5REP) of bilateral leg press exercise, with the same initial load and rest intervals between sets. Muscle biopsies (vastus lateralis) were taken before the first set, and after the first and the final sets. Compared with 5REP, 10REP resulted in a markedly greater decrease (P<0.05) of the power output, muscle PCr and ATP content, and markedly higher (P<0.05) levels of muscle lactate and IMP. Significant correlations (P<0.01) were observed between changes in muscle PCr and muscle lactate (R2 = 0.46), between changes in muscle PCr and IMP (R2 = 0.44) as well as between changes in power output and changes in muscle ATP (R2 = 0.59) and lactate (R2 = 0.64) levels. Reducing the number of repetitions per set by 50% causes a lower disruption to the energy balance in the muscle. The correlations suggest that the changes in PCr and muscle lactate mainly occur simultaneously during exercise, whereas IMP only accumulates when PCr levels are low. The decrease in ATP stores may contribute to fatigue
Indicadores antropométrico-nutricionales en la estratificación de riesgo cardiovascular en una población adulta
Introducción: las enfermedades cardiovasculares constituyen una de las causas más importantes de morbilidad, discapacidad y muerte prematura a nivel mundial. El control de los factores de riesgo es un elemento imprescindible para su prevención en la atención primaria, por lo cual es importante la estimación del riesgo.Objetivo: determinar el valor de indicadores antropométrico-nutricionales en la estratificación del riesgo cardiovascular en la población adulta.Métodos: se realizó un estudio observacional, descriptivo y transversal, la muestra estuvo conformada por 166 pacientes con edades comprendidas entre 35 y 74 años, pertenecientes al consultorio 22 del policlínico Carlos Juan Finlay de Santiago de Cuba, en el período septiembre a diciembre de 2017 donde se evaluó el índice de masa corporal, el índice cintura-cadera, índice de adiposidad corporal y riesgo cardiovascular global.Resultados: en los valores de los indicadores antropométricos-nutricionales en los diferentes grados de riego cardiovascular según sexo se muestra como en las mujeres el índice de masa corporal (p=0,002) y el índice de adiposidad corporal (p=0,007) permitieron diferenciar significativamente los grados de riesgo cardiovascular, no así el índice cintura-cadera (p=0,193); en cambio en los hombres se observaron diferencias significativas solamente en el índice de adiposidad corporal (p=0,042).Conclusiones: en la diferenciación de los niveles de riesgo cardiovascular global el índice de adiposidad corporal es útil para ambos sexos y el índice de masa corporal en las mujeres, no posibilitando esto el índice cintura-cadera

Anaerobic Energy Expenditure and Mechanical Efficiency during Exhaustive Leg Press Exercise
Information about anaerobic energy production and mechanical efficiency that occurs over time during short-lasting maximal exercise is scarce and controversial. Bilateral leg press is an interesting muscle contraction model to estimate anaerobic energy production and mechanical efficiency during maximal exercise because it largely differs from the models used until now. This study examined the changes in muscle metabolite concentration and power output production during the first and the second half of a set of 10 repetitions to failure (10RM) of bilateral leg press exercise. On two separate days, muscle biopsies were obtained from vastus lateralis prior and immediately after a set of 5 or a set of 10 repetitions. During the second set of 5 repetitions, mean power production decreased by 19% and the average ATP utilisation accounted for by phosphagen decreased from 54% to 19%, whereas ATP utilisation from anaerobic glycolysis increased from 46 to 81%. Changes in contraction time and power output were correlated to the changes in muscle Phosphocreatine (PCr; r = −0.76; P<0.01) and lactate (r = −0.91; P<0.01), respectively, and were accompanied by parallel decreases (P<0.01-0.05) in muscle energy charge (0.6%), muscle ATP/ADP (8%) and ATP/AMP (19%) ratios, as well as by increases in ADP content (7%). The estimated average rate of ATP utilisation from anaerobic sources during the final 5 repetitions fell to 83% whereas total anaerobic ATP production increased by 9% due to a 30% longer average duration of exercise (18.4±4.0 vs 14.2±2.1 s). These data indicate that during a set of 10RM of bilateral leg press exercise there is a decrease in power output which is associated with a decrease in the contribution of PCr and/or an increase in muscle lactate. The higher energy cost per repetition during the second 5 repetitions is suggestive of decreased mechanical efficiency
Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry
Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality
