Plataforma informática aplicada como ayuda al proceso de enseñanza-aprendizaje de la educación primaria y secundaria de la provincia de Córdoba: la integración de las nuevas tecnologías (ntics) para el proceso de enseñanza-aprendizaje en entornos virtuales y colaborativos como complemento a la enseñanza tradicional

Desde la Facultad de Ingenierí­a de la Universidad Católica de Córdoba, se pudo constatar a través de una investigación de campo las dificultades que presentaban los alumnos de nivel primario y medio para realizar sus tareas extra-Áulicas. Estas dificultades provenían en general de las siguientes categorías: a. alumnos que no tienen el suficiente grado de contención fuera del Ámbito netamente escolar. b. alumnos que no pueden recurrir a un adulto en sus hogares para solicitarles ayuda en sus tareas escolares. c. alumnos que, estando acompañados por familiares, estos no pueden acompañar la actividad de las tareas que los alumnos deben entregar en clases siguientes. Actualmente, esta situación persiste en un gran número de familias económicamente comprometidas, impidiendo que se logre una interacción efectiva entre los docentes, desde las propuestas de actividades curriculares, y los alumnos desde sus actividades extra- Áulicas (deberes o tareas). El presente proyecto, como plataforma educativa, inscripto en una realidad social compleja y de importancia vital para el desarrollo educativo de los alumnos intentará dar tratamiento a este problema ya no en forma particular sino en forma general y a varias disciplinas. El desafío de este proyecto multidisciplinario, en el que confluyen la Informática y Educación, es desarrollar un espacio para que los alumnos de nivel primario y nivel medio puedan encontrar trayectorias formativas extra-Áulicas mediadas por el conocimiento curricular y construyendo un lugar de encuentro e intercambio productivo, en este caso, en la red, en una aula virtual y en una experiencia extensionista mediada por la tecnología informática.Fil: Chiodi, Gustavo Alberto.

Plataforma informática aplicada como ayuda al proceso de enseñanza-aprendizaje de la educación primaria y secundaria de la Provincia de Córdoba: La integración de las Nuevas Tecnologías (NTICs) para el proceso de enseñanza-aprendizaje en entornos virtuales y colaborativos como complemento a la enseñanza tradicional

A partir del proyecto de Responsabilidad Social Universitaria del año 2008: “Aplicaciones del Análisis Matemático para el proceso de enseñanza aprendizaje de la Matemática: Escuelas de nivel medio de población económica comprometida de la ciudad de Córdoba”, de Gustavo A. Chiodi y Aldo Chami, realizado en la Facultad de Ingeniería de la Universidad Católica de Córdoba, se pudo constatar a través de una investigación de campo las dificultades que presentaban los alumnos para realizar sus tareas extra-áulicas. Estas dificultades provenían en general de las siguientes categorías: a. alumnos que no tienen el suficiente grado de contención fuera del ámbito netamente escolar. b. alumnos que no pueden recurrir a un adulto en sus hogares para solicitarles ayuda en sus tareas escolares. c. alumnos que, estando acompañados por familiares, estos no pueden acompañar la actividad de las tareas que los alumnos deben entregar en clases siguientes. Una mirada actual y objetiva sobre esta realidad y en base a estos antecedentes permitió determinar que esta situación persiste en un gran número de familias social y económicamente comprometidas. Así la interacción efectiva entre los docentes, desde las propuestas de actividades curriculares por un lado, y los alumnos desde sus actividades extra-áulicas (deberes o tareas) por el otro, se ve afectada fuertemente. El presente proyecto, como plataforma educativa, inscripto en una realidad social compleja y de importancia vital para el desarrollo educativo de los alumnos intentará dar tratamiento a este problema ya no en forma particular para cada alumno sino en forma general y a varias disciplinas. El desafío de este proyecto multidisciplinario, en el que confluyen la Informática y la Educación, es desarrollar un espacio para que los alumnos de nivel primario y nivel medio puedan encontrar en él trayectorias formativas extra-áulicas mediadas por el conocimiento curricular y construyendo un lugar de encuentro e intercambio productivo, en este caso, en la red, en una aula virtual y en una experiencia extensionista mediada por la tecnología informática. La plataforma informática educativa permitirá al alumno poder recurrir a un acompañamiento virtual en la realización de sus tareas en el marco curricular del proceso educativo y abandonar el concepto de mero consumidor de tecnologías a utilizarlas para generar nuevas alternativas y vínculos, donde de un modo creativo pueda generar conocimientoFil: Chiodi, Gustavo Alberto.

Genomic Determinants of Protein Abundance Variation in Colorectal Cancer Cells

Assessing the impact of genomic alterations on protein networks is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labeling to characterize the proteomic landscapes of 50 colorectal cancer cell lines and to decipher the functional consequences of somatic genomic variants. The robust quantification of over 9,000 proteins and 11,000 phosphopeptides on average enabled the de novo construction of a functional protein correlation network, which ultimately exposed the collateral effects of mutations on protein complexes. CRISPR-cas9 deletion of key chromatin modifiers confirmed that the consequences of genomic alterations can propagate through protein interactions in a transcript-independent manner. Lastly, we leveraged the quantified proteome to perform unsupervised classification of the cell lines and to build predictive models of drug response in colorectal cancer. Overall, we provide a deep integrative view of the functional network and the molecular structure underlying the heterogeneity of colorectal cancer cells

Global Survey of Outcomes of Neurocritical Care Patients: Analysis of the PRINCE Study Part 2

BACKGROUND: Neurocritical care is devoted to the care of critically ill patients with acute neurological or neurosurgical emergencies. There is limited information regarding epidemiological data, disease characteristics, variability of clinical care, and in-hospital mortality of neurocritically ill patients worldwide. We addressed these issues in the Point PRevalence In Neurocritical CarE (PRINCE) study, a prospective, cross-sectional, observational study. METHODS: We recruited patients from various intensive care units (ICUs) admitted on a pre-specified date, and the investigators recorded specific clinical care activities they performed on the subjects during their first 7 days of admission or discharge (whichever came first) from their ICUs and at hospital discharge. In this manuscript, we analyzed the final data set of the study that included patient admission characteristics, disease type and severity, ICU resources, ICU and hospital length of stay, and in-hospital mortality. We present descriptive statistics to summarize data from the case report form. We tested differences between geographically grouped data using parametric and nonparametric testing as appropriate. We used a multivariable logistic regression model to evaluate factors associated with in-hospital mortality. RESULTS: We analyzed data from 1545 patients admitted to 147 participating sites from 31 countries of which most were from North America (69%, N = 1063). Globally, there was variability in patient characteristics, admission diagnosis, ICU treatment team and resource allocation, and in-hospital mortality. Seventy-three percent of the participating centers were academic, and the most common admitting diagnosis was subarachnoid hemorrhage (13%). The majority of patients were male (59%), a half of whom had at least two comorbidities, and median Glasgow Coma Scale (GCS) of 13. Factors associated with in-hospital mortality included age (OR 1.03; 95% CI, 1.02 to 1.04); lower GCS (OR 1.20; 95% CI, 1.14 to 1.16 for every point reduction in GCS); pupillary reactivity (OR 1.8; 95% CI, 1.09 to 3.23 for bilateral unreactive pupils); admission source (emergency room versus direct admission [OR 2.2; 95% CI, 1.3 to 3.75]; admission from a general ward versus direct admission [OR 5.85; 95% CI, 2.75 to 12.45; and admission from another ICU versus direct admission [OR 3.34; 95% CI, 1.27 to 8.8]); and the absence of a dedicated neurocritical care unit (NCCU) (OR 1.7; 95% CI, 1.04 to 2.47). CONCLUSION: PRINCE is the first study to evaluate care patterns of neurocritical patients worldwide. The data suggest that there is a wide variability in clinical care resources and patient characteristics. Neurological severity of illness and the absence of a dedicated NCCU are independent predictors of in-patient mortality.status: publishe

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
