Factors associated with intestinal anastomosis failure in children: retrospective cohort analysis
No full textIntroducción: La falla de una anastomosis intestinal es un evento de alta morbilidad en la población pediátrica. Pese a esto, son pocos los estudios en niños dirigidos a evaluar potenciales factores de riesgo para este desenlace.
Métodos: Se llevó a cabo un estudio observacional analítico tipo cohorte retrospectiva en pacientes sometidos a anastomosis intestinales entre enero de 2017 y julio de 2023 en la Fundación HOMI (Bogotá, Colombia). Se describieron datos demográficos y se analizaron posibles factores de riesgo de falla de anastomosis mediante un modelo de regresión logística.
Resultados: Se identificaron 449 anastomosis en 404 pacientes. La población se caracterizó por una alta incidencia de patología aguda de alta complejidad (41.87% ASA mayor a III, 44.77% vigilancia postoperatoria en UCI). En el análisis multivariado, la única variable que se asoció con mayor riesgo de fallo de anastomosis fue la presencia de laparostomía (OR 7.86, IC95% 2.099 a 29.427, p=0.002).
Discusión y conclusiones: Dado que el único factor que incrementó el riesgo de falla de la anastomosis en esta cohorte fue el abdomen abierto, es posible afirmar que el criterio intraoperatorio del cirujano tiene alto valor pronóstico. Son necesarios más estudios en niños para explorar otros factores de riesgo y plantear herramientas predictivas que contribuyan a mejorar el diagnóstico temprano (Texto tomado de la fuente).Introduction: Failure of a pediatric intestinal anastomosis is a high-morbidity event. Despite this, few studies in children have aimed to evaluate potential risk factors for this outcome.
Methods: An observational, analytical, retrospective cohort study was conducted in patients who underwent intestinal anastomoses between January 2017 and July 2023 at HOMI Foundation (Bogotá, Colombia). Demographic data were described, and potential risk factors for anastomotic leak were analyzed using a logistic regression model.
Results: A total of 449 anastomoses in 404 patients were identified. The population was characterized by a high incidence of acute, high-complexity pathology (41.87% ASA > III, 44.77% postoperative ICU monitoring). In the multivariate analysis, the only variable associated with a higher risk of anastomotic leak was the presence of laparostomy (OR 7.86, 95% CI 2.099 to 29.427, p = 0.002).
Discussion and Conclusions: Given that the only factor increasing the risk of anastomotic leak in this cohort was open abdomen, we conclude that the surgeon’s intraoperative judgment holds significant prognostic value. Further studies in children are necessary to explore other risk factors and to develop predictive tools that may contribute to early diagnosis.Especialidades MédicasEspecialista en Cirugía PediátricaSe llevó a cabo un estudio observacional analítico tipo cohorte retrospectiva

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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
