Abstract	Introduction: Currently there is no consensus on the need for investigating knee ligamentous and meniscal injuries in a patient with a tibial plateau fracture. Consequently, many soft tissue injuries are likely undiagnosed and therefore untreated. The impact this has on long term knee outcomes is not well defined. We aimed to identify the impacts of various diagnostic methods on the management of meniscal injuries associated with tibial plateau fractures and evaluate the clinical outcomes. Materials and methods: We performed a systematic review using Pubmed, Medline, Embase, CINAHL and Cochrane following Cochrane guidelines. We included studies that operatively managed tibial plateau fractures and soft tissue injuries, which were diagnosed with either preoperative MRI, intra-operative arthroscopy or arthrotomy. Results: 18 articles with 884 people, with a mean age of 46.4 years were included. Soft tissue injuries were detected on MRI (32-73%) and arthroscopy (12-70%), of which the most common were lateral meniscal injuries (7-64% of tibial plateau fractures). When identified by arthroscopy and arthrotomy, these injuries were almost always treated, either by repair or debridement. The clinical outcomes of these patients were poorly reported, with a heterogenous use of patient reported outcome measures, and follow up time points. There were no randomised trials or control groups for comparative analysis, however operative treatment yielded good to excellent outcomes. Conclusion: There is a high incidence of concomitant soft tissue injuries with tibial plateau fractures, particularly lateral meniscal injuries. There are 2 main approaches to meniscal injuries: surgeons who don't investigate, don't treat, whilst surgeons who do investigate often do surgically treat. Although studies that treated these injuries achieved good to excellent results, the currently available evidence doesn't confirm treatment superiority. As there is plausibility for better outcomes, randomised studies are needed to further investigate this clinical question.

Abstract	Las limitaciones financieras y los escasos recursos económicos disponibles en las universidades son barreras importantes que los jóvenes encuentran para ingresar y concluir exitosamente con un título universitario en la región Latinoamericana. Dado este problema, esta investigación se centró en dos casos de instituciones de educación universitaria (IES) privadas que implementan mecanismos de financiamiento innovadores, que generan valor social y económico para los estudiantes. Estas instituciones se destacan por incluir en sus enunciados misionales estas dimensiones que buscan disminuir la brecha de desigualdad en el acceso a la educación superior.La investigación utiliza un enfoque cualitativo con el estudio de dos universidades ubicadas en Perú y Colombia. La recolección de datos se basó en entrevistas a directivos de las IES, en la observación del entorno de estudio y en el análisis de documentos e informes financieros institucionales de las dos instituciones. Los resultados indicaron que las IES desarrollan mecanismos de financiamiento basados en transacciones comerciales y no comerciales. La información obtenida permitió concluir que las unidades de negocio, como generadoras de valor social y económico para los estudiantes y las universidades, son trascendentales para el crecimiento económico y sostenible de la misión institucional.

Abstract	Objective Colombia hosts 1.8 million displaced Venezuelans, the second highest number of displaced persons globally. Colombia's constitution entitles all residents, including migrants, to life-saving health care, but actual performance data are rare. This study assessed Colombia's COVID-era achievements. Methods We compared utilization of comprehensive (primarily consultations) and safety-net (primarily hospitalization) services, COVID-19 case rates, and mortality between Colombian citizens and Venezuelans in Colombia across 60 municipalities (local governments). We employed ratios, log transformations, correlations, and regressions using national databases for population, health services, disease surveillance, and deaths. We analyzed March through November 2020 (during COVID-19) and the corresponding months in 2019 (pre-COVID-19). Results Compared to Venezuelans, Colombians used vastly more comprehensive services than Venezuelans (608% more consultations), in part due to their 25-fold higher enrollment rates in contributory insurance. For safety-net services, however, the gap in utilization was smaller and narrowed. From 2019 to 2020, Colombians' hospitalization rate per person declined by 37% compared to Venezuelans' 24%. In 2020, Colombians had only moderately (55%) more hospitalizations per person than Venezuelans. In 2020, rates by municipality between Colombians and Venezuelans were positively correlated for consultations (r = 0.28, p = 0.04) but uncorrelated for hospitalizations (r = 0.10, p = 0.46). From 2019 to 2020, Colombians' age-adjusted mortality rate rose by 26% while Venezuelans' rate fell by 11%, strengthening Venezuelans' mortality advantage to 14.5-fold. Conclusions The contrasting patterns between comprehensive and safety net services suggest that the complementary systems behaved independently. Venezuelans' lower 2019 mortality rate likely reflects the healthy migrant effect (selective migration) and Colombia's safety net healthcare system providing Venezuelans with reasonable access to ...

Abstract	En este trabajo, se desarrolló un sistema económico de escaneo tridimensional (3D) que permite obtener información de la estructura física de un determinado objeto a partir de la cual, se genera un modelo digital. Este sistema opera proyectando un haz de luz láser en forma de línea sobre el objeto, mientras rota sobre su propio eje (eje z), el haz de luz crea un perfil del objeto, el cual es capturado mediante vídeo de alta definición (HD) por una cámara. A través del procesamiento digital de las imágenes capturadas se obtienen los vértices del objeto y se construye el modelo tridimensional. Para llevar a cabo esta tarea, el escáner 3D está formado por un conjunto de elementos de hardware y software libre como lo son: la plataforma Arduino, que permite realizar el control del hardware de escaneo, y un software desarrollado en C++ que implementando las librerías OpenCv y OpenGl, permite la realización de las tareas de procesamiento y análisis de imágenes. Estos elementos hacen que este desarrollo, se constituya como incursión económica en la tecnología de escaneo laser tridimensional.

Abstract	Background: Open tibia fractures are a common injury following road traffic collisions and place a large economic burden on patients and healthcare systems. Summarising their economic burden is key to inform policy and help prioritise treatment. Methods: All studies were identified from a systematic search of Medline, Embase and the Cochrane Central Register of Controlled Trials. We included any human with a diagnosed open tibia fracture, following any intervention. The primary outcome was any costs reported or patient return to work status. Secondary outcomes included average length of stay, wage loss, absenteeism and complications such as infection, amputation and nonunion. Data was extracted and we performed a descriptive narrative summary. Results: We reviewed 1,204 studies from our searches. A total of 34 studies were included from 14 different countries. The average age was 37.7 years old and 76% of the patients were male. 6.5% were Gustilo I, 12% Gustilo II and 82% Gustilo III. Initial direct hospitalisation costs were reported to be between £356 to £126,479 with an average length of stay of 56 days (3.1-244). 89% of participants were working pre-injury, 60% fully returned to work, 17% returned to work part time or changed profession and 22% did not return to work at one-year. The most common complications reported were 22% infection, 11% nonunion and 16% amputation. Mean follow-up duration for the studies was 25 months. Conclusion: The economic burden of open tibia fractures varies greatly, but it is costly for both hospitals and patients. The current evidence is predominantly from high-income countries (HICs), especially the USA. Further research is required to investigate the costs of open tibia fractures using validated costing tools, especially in low-income countries (LICs), to help inform and direct policy.

Abstract	La Responsabilidad Social Universitaria (RSU) supone dos vertientes: una orientada a responder las demandas de sus públicos; y otra, dirigida a la trascendencia del actuar socialmente responsable a través de la formación de individuos. El propósito de esta investigación es describir la RSU en la Corporación Universitaria Adventista, a fin de mostrar la perspectiva y aportes como institución confesional hacia un modelo de gestión de la Responsabilidad Social Universitaria. Posee un enfoque mixto, y los instrumentos derivan del modelo de Vallaeys, De la Cruz y Sasia (2009). Los hallazgos muestran que muchos componentes de la RSU están implícitos en el accionar de la Corporación Universitaria Adventista, aunque no exista intencionadamente un modelo para gestionar la Responsabilidad Social Universitaria, tener los principios bíblicos como pilares de la gestión organizacional y de la formación, genera impactos positivos en sus diferentes públicos, resaltando la trascendencia de la formación integral que of rece su proyecto educativo
