Correlation of sleep quality and academic burden in medical students of El Bosque University, Colombia 2019
Get PDFLa calidad de sueño representa una problemática importante de salud pública debido a la importancia que tiene el descanso para el cuerpo que muchas veces se pasa por alto. En el caso de los estudiantes, se tiene que se adquieren hábitos de vida poco saludables que traen consecuencias sobre su salud física y mental. Para los estudiantes de medicina se piensa en un escenario aún más complejo debido a la fuerte carga académica que tiene la carrera. Por tal motivo el objetivo de esta investigación es la de analizar la correlación de dos variables: la carga académica y su incidencia sobre la calidad y la higiene de los estudiantes. Esto se va a realizar sobre una muestra de estudiantes inscritos en el período 2018-II en la Universidad del Bosque de la ciudad de Bogotá bajo un paradigma de estudio observacional de tipo descriptivo y de corte transversal. Complementario a lo anterior, se emplea el índice de Calidad de Sueño de Pittsburgh sobre la muestra para medir su calidad de sueño. En segundo lugar también se va a indagar sobre la carga académica a partir de los créditos inscritos por el estudiante para poder finalmente contrastar y relacionar estas dos variables.The quality of sleep represents an important public health problem due to the importance of rest for the body that is often overlooked. In the case of students, it is necessary to acquire unhealthy lifestyle habits that have consequences on their physical and mental health. For medical students, an even more complex scenario is thought of due to the strong academic burden of the career. For this reason, the objective of this research is to analyze the correlation of two variables: the academic load and its impact on the quality and hygiene of the students. This is going to be done on a sample of students enrolled in the 2018-II period at the Universidad del Bosque in the city of Bogotá under a descriptive and cross-sectional observational study paradigm. Complementary to the above, the Pittsburgh Sleep Quality Index is used on the sample to measure your sleep quality. Secondly, the academic burden will also be investigated based on the credits registered by the student in order to finally contrast and relate these two variablesInstituto Nacional de Salu
Sobrevida en pacientes receptores de trasplante renal con injerto proveniente de donantes vivos frente a donantes con muerte cerebral – Una revisión sistemática
No full textActualmente el trasplante renal es la segunda terapia de reemplazo renal más usada para el tratamiento de la enfermedad renal crónica en estadio avanzado (ESRD en inglés), después de la terapia dialítica (hemodiálisis y la diálisis peritoneal). En el año 2015, 979.415 personas en Colombia fueron diagnosticadas con enfermedad renal crónica y de ellas, 34.470 requirieron algún tipo de terapia de trasplante renal, siendo la terapia dialítica en el 80% de los casos. No obstante, este tipo de terapia representa una gran carga para el sistema de salud debido a la elevada cantidad de recursos necesarios para la misma, lo cual ha llevado a que la ERC sea catalogada como una enfermedad de alto costo, por lo que en la actualidad se están realizado diversos análisis con el fin de reconocer las variables que optimizan la funcionalidad del trasplante renal buscando evitar retornar a terapias de reemplazo menos costo-efectivas y, a su vez, de mejorar la sobrevida del paciente trasplantado a largo plazo (1, 2, 4, 6). Por esta razón, el objetivo de este trabajo es determinar cuáles son las diferencias en la sobrevida a largo plazo de los pacientes receptores de trasplante renal en función de su procedencia, tanto en donantes vivos como en muerte cerebral.Currently, kidney transplantation is the second most used therapy for the treatment of chronic kidney disease (CKD). In 2015 there were 79,948 kidney transplants worldwide, 869 transplants were made in Colombia and there are approximately one million people with a diagnosis of CKD in this country, which explains that about 125 patients per million inhabitants use this kind of renal replacement modality. Other therapies that are being used are hemodialysis and peritoneal dialysis, whose cost represents a great burden for the health system and it has made that CKD gets classified as a high-cost disease (1, 2, 4, 6)
Determinación de los efectos en la salud de los trabajadores del programa de control de vectores expuestos laboralmente a organoclorados en tres departamentos de Colombia 2013
No full textObjetivo: Evaluar la exposición a plaguicidas organoclorados empleados en salud publica en la población trabajadora del programa de control de vectores en tres regiones de Colombia en 2013.\ud
Métodos: Se realizó un estudio descriptivo de corte transversal en el grupo de trabajadores del programa de control de enfermedades transmitidas por vectores -ETV- (coordinadores, técnicos, entomólogos, técnicos y auxiliares) de los departamentos de Meta, Nariño y Risaralda. A todos los participantes se les realizó una entrevista en la cual se recogió, mediante cuestionario, información de las tres variables de muestreo: sociodemográficas, ocupacionales, clínicas y toxicológicas. Se determinaron los niveles de 13 organoclorados en suero mediante cromatografía de gases en el Instituto Nacional de Salud. Se llevó a cabo un análisis descriptivo y se llevo a cabo un análisis para determinar la distribución de medias entre variables de exposición ocupacional (Ji2 para cualitativas y U de Mann-Whitney para cuantitativas). Posteriormente, se llevó a cabo un análisis multivariado para estimar la asociación controlando por variables de antigüedad, exposición laboral a organoclorados.\ud
Resultados: El reporte de manipulación de insecticidas organoclorados fue del 39,1%. El 100% de los trabajadores que usaron organoclorados refirieron el uso DDT. El 7,5% (n=3) refirieron el uso de Aldrin. Los organoclorados fueron hexaclorbenceno, hexaclorocicloexano, heptacloro, heptaclorepoxi, α-Clordano, 4,4-DDT, 4,4-DDE, β -endosulfan, 2,4- DDT, endosulfan sulfato y mirex. Los organoclorados con niveles pico más altos fueron β-HCH, 4,4- DDT y α –HCH.

Letter to the editor on “Asymptomatic infection by SARS 2 coronavirus: Invisible but invincible” by Nikolai et al. 2020
No full textWe send this letter regarding the article "Asymptomatic infection by SARS 2
coronavirus: invisible but invincible" published in the International Journal of
Infectious Diseases (Nikolai et al. 2020). The review was interesting in many
aspects, particularly those related to the lack of a widely accepted definition of
asymptomatic carriers and presymptomatic patients, as well as the need to include
these types of cases in regular epidemiological surveillance
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
