Small intestine bacterial overgrowth and irritable bowel syndrome-related symptoms: experience with Rifaximin.
No full textAIM: To estimate the prevalence of small intestinal bacterial overgrowth (SIBO) in our geographical area (Western Sicily, Italy) by means of an observational study, and to gather information on the use of locally active, non-absorbable antibiotics for treatment of SIBO. METHODS: Our survey included 115 patients fulfilling the Rome II criteria for diagnosis of irritable bowel syndrome (IBS); a total of 97 patients accepted to perform a breath test with lactulose (BTLact), and those who had a positive test, received Rifaximin (Normix, Alfa Wassermann) 1200 mg/d for 7 d; 3 wk after the end of treatment, the BTLact was repeated. RESULTS: Based on the BTLact results, SIBO was present in about 56% of IBS patients, and it was responsible for some IBS-related symptoms, such as abdominal bloating and discomfort, and diarrhoea. 1-wk treatment with Rifaximin turned the BTLact to negative in about 50% of patients and significantly reduced the symptoms, especially in those patients with an alternated constipation/diarrhoea-variant IBS. CONCLUSION: SIBO should be always suspected in patients with IBS, and a differential diagnosis is done by means of a "breath test". Rifaximin may represent a valid approach to the treatment of SIBO
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
Colpoisterectomia con colpocleisi per prolasso utero-vaginale completo nelle donne di età > 65 anni
Full text linkObiettivo: riportare l’outcome obiettivo e soggettivo a lungo termine dopo colpoisterectomia con colpocleisi nelle donne avanti negli anni. Materiali e metodo: abbiamo condotto uno studio retrospettivo su 32 pazienti di età > 65 anni. Le caratteristiche delle pazienti, i dati
dell’intervento e l’outcome obiettivo sono stati ottenuti dalla consultazione ambulatoriale delle cartelle cliniche delle pazienti. I dati soggettivi sono stati ottenuti mediante intervista telefonica standardizzata. Risultati: 32 pazienti di età compresa tra i 65 e gli 85 anni con
prolasso utero-vaginale di 3° grado, durante un tempo di 6 anni, sono state trattate con colpoisterectomia, colpocleisi, duplicatura sub-uretrale, accostamento alto degli elevatori, colporrafia anteriore e posteriore. La durata media dell’intervento è stata di 83 min. (range 55-130 min), il decremento medio dell’Hb è stato di 2,1 mg/dl (range 0,5-2,8 mg/dl) e la degenza media ospedaliera di 8,3 giorni (range 6-16 giorni). La recidiva del prolasso è stata osservata in 2 casi, i sintomi di incontinenza da sforzo persistono in 2 casi e si ripresentano in altri 2 casi. Non sono state osservate complicanze intraoperatorie, invece è stata osservata una complicanza postoperatoria (ematoma pelvico). Il follow-up va da un minimo di 6 mesi ad un massimo di 5 anni. All’intervista telefonica 18 pazienti si sono dichiarate molto soddisfatte, 10 soddisfatte e 4 insoddisfatte. Conclusioni: la colpoisterectomia con colpocleisi offre un trattamento efficace nel trattamento del prolasso utero-vaginale completo nelle donne avanti negli anni
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
