Clinical and microbiological profile of patients with a confirmed diagnosis of histoplasmosis at the Central Military Hospital.
No full textLa histoplasmosis es una enfermedad endémica en las Américas, pero no es un evento de notificación obligatoria en muchos países incluido el nuestro, lo que genera el desconocimiento de las características clínicas y epidemiológicas de la enfermedad, produciendo demoras en el diagnóstico y su tratamiento, impactando negativamente en el pronóstico de los pacientes, en especial la población militar. Esta fue una serie de 29 acasos en donde se realizó descripción clínica y microbiológica de los pacientes usuarios del subsistema de sanidad de las fuerzas militares, que fueron atendidos en el Hospital Militar Central, esto a través de la revisión de las historias clínicas electrónicas registradas en dinámica gerencial entre 2012 y 2020, se encontró que el 89,65% fueron hombres, con promedio de edad de 35 años, el síntoma más frecuente fue la fiebre en el 65,52%, la presentación clínica más frecuente de la histoplasmosis fue la histoplasmosis diseminada en el 86,21% (25 pacientes), seguido de la presentación con nódulos pulmonares en el 13,79% (4 pacientes), de acuerdo a la clasificación de enfermedad fúngica invasiva el 44,83% presentó enfermedad posible y el 55,17% enfermedad probada.
En nuestro estudio se describieron varias de las características clínicas y paraclínicas al ingreso a la institución de manera muy detallada lo que permite seguir aumentando el conocimiento nacional sobre la epidemiología, características clínicas, paraclínicas y de tratamiento en los pacientes con histoplasmosis, generando la necesidad de la búsqueda activa y la notificación obligatoria de una enfermedad endémica como esta.Histoplasmosis is an endemic disease in the Americas, but it is not a mandatory notification event in many countries, including ours, which generates ignorance of the clinical and epidemiological characteristics of the disease, producing delays in diagnosis and treatment, impacting negatively in the prognosis of patients, especially the military population. This was a series of 29 cases in which a clinical and microbiological description was made of the patients who were users of the health subsystem of the military forces, who were treated at the Central Military Hospital, through the review of the electronic medical records registered in managerial dynamics between 2012 and 2020, it was found that 89.65% were men, with an average age of 35 years, the most frequent symptom was fever in 65.52%, the most frequent clinical presentation of histoplasmosis was disseminated histoplasmosis in 86.21% (25 patients), followed by presentation with pulmonary nodules in 13.79% (4 patients), according to the classification of invasive fungal disease, 44.83% presented possible disease and the 55.17% proven disease.
In our study, several of the clinical and paraclinical characteristics on admission to the institution were described in a very detailed manner, which allows us to continue increasing national knowledge about the epidemiology, clinical, paraclinical and treatment characteristics of patients with histoplasmosis, generating the need for active search and mandatory notification of an endemic disease like this.NingunoContenido

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
