Determinar si los factores dislipidemia, obesidad, hipertensión arterial y diabetes mellitus se encuentran asociados a infarto agudo de miocardio. Hospital Regional Docente de Trujillo. 2013 - 2015
Material y Método: Se realizó un estudio de casos y controles, observacional, retrospectivo, transversal y analítico, con un total de 180 historias clínicas del servicio de Cardiología (mujeres y hombres con una media de edad de 60 +- 20 años). Los pacientes fueron asignados a uno de dos grupos en base a si tenían o no diagnóstico de infarto agudo de miocardio (IMA). El primer grupo, (casos), estuvo compuesto por 60 pacientes que cumplían los criterios diagnósticos de IMA, y que cumplían con cualquiera de los siguientes factores en estudio. El segundo grupo, (controles), estuvo compuesto por 120 pacientes que no tenían diagnóstico de IMA y que cumplían con cualquiera de los factores antes mencionados. Se hizo uso de la prueba estadística Chi cuadrado para las variables cualitativas; para verificar la significancia estadística de las asociaciones entre las mismas.
Resultados: Se halló asociación entre la dislipidemia y el IMA con un odds ratio (OR) 9.07 (IC 95%: 1.86 - 44.2) con un nivel de significancia muy alto (p 0.05). Por otro lado, mediante el Test de Fisher sí se encontró una asociación significativa entre la obesidad y el IMA (p < 0.05).
Conclusión: La dislipidemia y la obesidad son factores de riesgo asociados al desarrollo de IMA, mientras que la HTA y diabetes mellitus no lo son. Asimismo, tanto la dislipidemia con la HTA y la dislipidemia con la obesidad son factores de riesgo asociados a IMA. Sin embargo, la HTA con la diabetes mellitus, la dislipidemia con la diabetes mellitus, y la HTA con la obesidad no lo constituyen. Además, la presencia de 3 factores simultáneamente no conforma un factor de riesgo.Determine if the factors dyslipidemia, obesity, arterial hypertension and diabetes mellitus are associated with acute myocardial infarction. Regional Teaching Hospital of Trujillo. 2013 - 2015
Material and Methods: A study of cases and controls, observational, retrospective, cross-sectional and analytical was performed, with a total of 180 medical histories of patients in the service of Cardiology of the Regional Teaching Hospital of Trujillo (women and men with an average age of 60 +- 20 years). The patients were assigned to one of two groups based on whether or not they had a diagnosis of acute myocardial infarction (AMI). The first group (cases) contained 60 patients who met the diagnostic criteria for AMI, and met any of the following factors under study. The second group (controls) consisted of 120 patients who didn’t have diagnosis of AMI and who met any of the mentioned factors. Statistical Chi square Test for qualitative variables was made; to verify the statistical significance of the associations.
Results: The odds ratio (OR) found from the association between dyslipidemia and AMI was 9.07 (CI 95 %: 1.86 - 44.2) with a very high level of significance (p 0.05). On the other hand, by the Fisher Test a significant association between obesity and AMI (p < 0.05) was found.
Conclusions: Dyslipidemia and obesity are risk factors associated with the development of AMI, while AHT and DM are not. Also, both dyslipidemia with hypertension and dyslipidemia with obesity are risk factors associated with AMI. However, hypertension with diabetes mellitus, dyslipidemia with diabetes mellitus and hypertension with obesity are not. Furthermore, the presence of three factors simultaneously does not form a risk factor.Tesi
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
