Mortalidad en pacientes hospitalizados por COVID-19 durante la primera ola en una institución de tercer nivel de Neuquén
Full text linkEn diciembre de 2019, se detectó un brote de enfermedad por un nuevo coronavirus que evolucionó en pandemia con severa morbilidad respiratoria y mortalidad. Los sistemas sanitarios debieron enfrentar una cantidad inesperada de pacientes con insuficiencia respiratoria. En Argentina, las medidas de cuarentena y control sanitario retrasaron el primer pico de la pandemia y ofrecieron tiempo para preparar el sis-tema de salud con infraestructura, personal y protocolos basados en la mejor evidencia disponible en el momento. En una institución de tercer nivel de Neuquén, Argentina, se desarrolló un protocolo de atención para enfrentar la pandemia adaptado con la evolución de la mejor evidencia y evaluaciones periódicas de la mortalidad hospitalaria.
Métodos: Estudio de cohorte observacional para evaluar la evolución de pacientes con COVID-19 con los protocolos asistenciales por la mortalidad hospitalaria global y al día 28 en la Clínica Pasteur de Neuquén en 2020.
Resultados: Este informe describe los 501 pacientes diagnosticados hasta el 31 de diciembre de 2020. La mortalidad general fue del 16,6% (83/501) y del 12,2% (61/501) al día 28 de admisión. En los 139 (27,7%) pacientes con ventilación mecánica, la mortalidad general y a los 28 días fue de 37,4% (52/139) y 28,1% (38/139) fallecieron, respectivamente. Los factores de riesgo identificados fueron edad, comorbilidades y altos requerimientos de oxígeno al ingreso.
Conclusión: La mortalidad observada en los pacientes hospitalizados en nuestra institución en la primera ola de la pandemia COVID-19 fue similar a los informes internacionales y menor que la publicada en Argentina para el mismo período.Fil: Zabert, Gustavo.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
No full textWe 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
Utilidad de la escala PUMA electrónica para la detección de EPOC en atención primaria: un estudio de implementación real.
Full text linkIntroducción: La Enfermedad Pulmonar Obstructiva Crónica (EPOC) es una causa prin-
cipal de morbilidad y mortalidad a nivel global. El subdiagnóstico es frecuente debido a
la baja disponibilidad de la espirometría en atención primaria. Por lo tanto, es oportuno
implementar una estrategia sencilla y accesible, basada en cuestionarios, para la selec-
ción de individuos que requieran de una espirometría diagnóstica.
Métodos: Estudio de corte transversal en cinco centros de atención primaria (CAP) de
Argentina con el objetivo de determinar la prevalencia de EPOC en una población de
pacientes de alto riesgo y evaluar la utilidad del escore PUMA usando una herramienta
electrónica. El tamaño muestral se estimó entre 683 y 893 individuos, considerando una
prevalencia entre 20 y 30% con un intervalo de confianza (IC) del 95%.
Resultados: En un periodo de 3 meses, se encuestaron 866 pacientes y 836 que cum-
plieron criterios de inclusión. El escore PUMA fue ≥ 5 en 503 pacientes y 440 pacientes
realizaron espirometría. 63 pacientes fueron excluidos (52 no asistieron a la espirome -
tría, 8 por negativa a participar y 3 por seguridad). Por espirometría, se diagnosticaron
120 casos de EPOC, que representa una prevalencia del 27,3% en la población estudia-
da y del 23,5% para el subgrupo de pacientes con escore PUMA ≥ 5.
Conclusión: El escore PUMA, integrado en una herramienta electrónica, probó ser una
herramienta adecuada para la selección de pacientes para el diagnóstico espirométri-
co de EPOC en atención primaria.Background: COPD is a major cause of morbidity and mortality worldwide. Underdiag-
nosis is frequently reported since spirometry is not widely available in primary care set-
tings. Therefore, a simple and accessible questionnaire-based strategy to select indi-
viduals for mandatory spirometry is desirable.
Methods: A cross-sectional study was performed to determine COPD prevalence
among high-risk patients in five primary care facilities in Argentina and to assess the
utility of PUMA score embedded in an electronic tool. Sample size was estimated be-
tween 683 to 893 cases for a prevalence of 20- 30% (with a CI of 95%), respectively.
Results: Over a 3-month period, a total of 866 patients were surveyed, with 836 meet-
ing the inclusion criteria. The PUMA score was ≥ 5 in 503 patients and 440 patients un-
derwent spirometry. Sixty-three patients were excluded (52 did not attend spirometry,
8 refused to participate and 3 for safety reasons). Spirometry diagnosed 120 cases of
COPD, representing a COPD prevalence of 27.3% in the study population and 23.5% in
the subgroup of patients with a PUMA score ≥ 5.
Conclusion: The PUMA score embedded in an electronic tool performed appropriately
to select cases to diagnose COPD by spirometry in a primary care setting.Fil: Zabert, Gustavo E. Universidad Nacional del Comahue. Facultad de Ciencias Médicas; Argentina.Fil: Zabert, Gustavo E.
