Revisión sistemática “Incidencia de las secuelas de infección por Chlamydia trachomatis" / Systematic review "Incidence of sequelae of Chlamydia trachomatis infection"
Get PDFINTRODUCCIÓN: La infección del tracto genital femenino por Chlamydia trachomatis, es una de las enfermedades de transmisión sexual más prevalentes en el mundo. La prevalencia va desde 11.4% hasta el 20% en poblaciones de alto riesgo, y entre pacientes asintomáticas desde 3.0% en la población general a 9.5% entre estudiantes universitarias, generando consecuencias de la enfermedad relevantes. OBJETIVO: Determinar cuál es la incidencia de aparición de embarazo ectópico, dolor pélvico crónico e infertilidad como secuelas de infección por Chlamydia trachomatis. DISEÑO: Se investigó en las bases de datos de la librería COCHRANE, en las bases de datos MEDLINE (acceso a través de PubMed y Gateway), y BVS, Embase y LILACS, y se hizo búsqueda manual de referencias de artículos y textos, desde 1985 hasta agosto del 2011. RESULTADOS: Se realizaron múltiples búsquedas, arrojando 87 artículos en PubMed, mientras que por BVS arrojó 36 artículos; además de 4 artículos encontrados en EMBASE y cero por LILACS, quedando 138 en un conglomerado, y se dejaron 69 artículos, de los cuales se encontraron en texto completo 40 y sólo 8 cumplieron con los criterios de inclusión. CONCLUSIONES: Existen en la literatura, resultados que confirman que la Clamidia es causal de embarazo ectópico e infertilidad, de dolor pélvico crónico no existe relación causal directa, sin embargo son estudios sin óptimo nivel de evidencia. Ault et al 1998,en un grupo pequeño de pacientes encontró un aumento del riesgo de infertilidad con un OR 11.25. Mientras que Dutta, 2008, encontró una incidencia de 33% de infertilidad secundaria a C. trachomatis con OR 1.7 (0.92-3.13).Para embarazo ectópico, Low et al 2005, comparando las positivas para C. trachomatis con las negativas, se encuentra un riesgo aumentado de aHR, 1.3; 95% CI, 0.9–1.7. Igualmente sugiere que el 20–25% de mujeres con EPI podrían tener un embarazo ectópico o quedar infértiles. / Abstract. INTRODUCTION: The female genital tract infection with Chlamydia trachomatis is one of the most prevalent sexually transmitted disease in the world. The prevalence ranges from 11.4% to 20% in high-risk populations, and among asymptomatic patients from 3.0% in the general population to 9.5% among college students, generating significant consequences. OBJECTIVE: To determine the incidence of occurrence of ectopic pregnancy, chronic pelvic pain and infertility as aftermath of Chlamydia trachomatis infection. DESIGN: We investigated the databases of the Cochrane Library, in the MEDLINE database (access via PubMed and Gateway), and BVS, Embase, and LILACS, and a manual search of references of articles and texts from 1985 to August 2011. RESULTS: There were multiple searches, yielding 87 articles in PubMed, while on BVS yielded 36 articles, including 4 items found in EMBASE and LILACS zero, leaving 138 in a cluster, and left 69 articles, which were found Full Text 40 and only 8 met the inclusion criteria. CONCLUSIONS: According to the literature, results which confirm that Chlamydia is a cause of ectopic pregnancy and infertility, about chronic pelvic pain there is no direct causal relationship, however, are studies without optimal level of evidence. Ault et al 1998, in a small group of patients found an increased risk of infertility with an OR 11.25. While Dutta, 2008, found an incidence of 33% of infertility secondary to C. trachomatis with OR 1.7 (0.92-3.13). For ectopic pregnancy, Low et al 2005, comparing positive for C. trachomatis with the negative, there is an increased risk of aHR, 1.3, 95% CI, 0.9-1.7. Also suggests that 20-25% of women with PID may have an ectopic pregnancy or become infertile.Otr

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

Metodología: Estudio retrospectivode historias clínicas de gestantes y nacidos vivosen el Hospital La Victoria sede Materno Infantil ESE III nivel, del 1 de enero al 31 de octubre de 2010. Descripción de variables demográficas de pacientes con sífilis y evaluación de las condiciones que impactan en el tratamiento y seguimiento de las pacientes. Resultados: Seidentificaron 40casos de sífilis gestacional: 15% abortos; 10% embarazadas a la fecha de corte; 72.5% durante el parto; y 2.5% en puerperio. Las variables demográficas relevantes fueron: afiliación a régimen subsidiado y vinculado (85%); 30% separadas y solteras; 85% entre 18 y 35 años;55.5% educación básicaincompleta, 12% analfabetas. 92.5% multíparas, 77.5% estadio latente indeterminado. Además, 24 casos de sífilis congénita: Capurro entre 36 y 40 semanas (100%), bajo peso al nacer (20%), APGAR mayor de 7 (100%), examen clínico anormal (16%), neurosífilis (8%). Existe subregistro del seguimiento clínico institucional y serológico materno y neonatal. Conclusión: La sífilis congénita y gestacional afectan a grupos poblacionales vulnerables de nuestra comunidad.

Goal: to perform a descriptive analysis of the screening, diagnosis, treatment and monitoring of syphilis during pregnancy (SDP) and congenital syphilis (CS) in a third level institution in Bogota; to determine the difficulties that nowadays influence the integral handling of the disease. Methodology: Retrospective study of the clinical history of pregnant women and births in La Victoria Hospital - Materno Infantil ESE III level, from January the first to October 31st 2010. Description of demographic variables from patients with syphilis and analysis of the circumstances that influence the treatment and monitoring of the patients. Results: 40 cases of SDP were detected: 15% abortions; 10% pregnant women at the end of the study; 72.5% during labor; and 2.5% at puerperium. The relevant demographic variables were: lack of social security (85%); 30% divorced and single women; 85% women between 18 and 35 years old; 55.5% with incomplete elementary school, 12% were illiterates. 92.5% multiparous women, 77.5% latent syphilis of unknown duration. Also, there were 24 cases of CS: gestational age between 36 and 40 weeks (100%), underweight at birth (20%), APGAR score over 7 (100%), abnormal clinical tests (16%), neurosyphilis (8%). There is a lack in the records of the maternal as well as neonatal clinical and serological monitoring. Conclusion: SDP and CS affect vulnerable population groups from our community. It is necessary to integrally handle clinical data from each mother and her newborn, to determine the corresponding therapeutic scenario and to optimize the clinical treatment, to reduce the time spent in the hospital, the treatment to newborns and to ensure the cure of the disease.Otr
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
