Abstract
Aim: This study aims to verify if the duration of postoperative ileus (POI), in patients undergoing abdominal surgery, is related to the surgical approach used (open or laparoscopic) or rather to the manipulation of bowel loops.
Materials and methods: Ninety patients, undergoing elective colon resection for cancer, were randomized in three groups with different surgical approaches: open technique with extensive manipulation of intestinal loops (GROUP A), open technique with minimal manipulation (GROUP B) and laparoscopic technique (GROUP C). Return of bowel functions was investigated by: detection of bowel sounds, passage of flatus and passage of stool.
Results: Detection of bowel sounds occurred after 2.18 days in GROUP A, after 1.35 days in GROUP B and after 1.19 days in GROUP C. Return of flatus occurred after 3.51 days in Group A, after 2.53 days in GROUP B and after 2.30 days in GROUP C. Passage of stool occurred after 4.48 days in GROUP A, after 3.75 days in GROUP B and after 3.61 days in GROUP C. In all end-points analyzed, differences between GROUP A and GROUP B and between GROUP A and GROUP C are significant (P< 0.01) whereas the differences between GROUP B and GROUP C are not significant (P > 0.01).
Conclusions: In colon surgery open technique with minimal manipulation of loops obtains similar results in those of the laparoscopic technique, in terms of resolution of postoperative ileus
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
Gel piastrinico. Trattamento del piede diabetico e dell’osteomielite fistolizzata. Revisione della letteratura e nostra esperienza in 61 casi clinici
Full text linkGEL PIASTRINICO: TRATTAMENTO DEL PIEDE DIABETICO E DELL’OSTEOMIELITE FISTOLIZZATA. REVISIONE DELLA LETTERATURA E NOSTRA ESPERIENZA IN 61 CASI CLINICI
Introduzione: la nostra esperienza evidenzia l’utilità del gel piastrinico (GP) nel trattamento
ambulatoriale delle piaghe torpide della pianta del piede in paziente diabetico e delle ulcerazioni
torpide che richiedevano periodi lunghissimi di medicazioni complesse, senza raggiungere il
risultato atteso. Materiali e Metodi: la metodica personale prevede il curettage dopo disinfezione e
debridement della piaga, l’inoculazione di 1-4 UI di insulina pronta alla base del cratere ulcerativo
e quindi l’applicazione di 5 ml di GP con 1 ml di Trombina autologa attivata. L’applicazione si
esegue facendo gocciolare il concentrato piastrinico su Hyalofill-F Fidia® Italia sul quale si fa,
quindi, gocciolare l’attivatore ottenendo un panno morbido, elastico-gelatinoso, pronto a riempire
la cavità da trattare. Il supporto inerte riassorbibile in acido ialuronico impedisce la dispersione
della parte liquida o non completamente gelificata, ricca dei fattori di crescita (PDGF, TGF, EGF)
che stimolano la moltiplicazione dei fibroblasti i quali aumentano di numero e depositano matrice
connettivale, trasformando la piaga torpida con la fioritura dei bottoni di granulazione. In caso di
ferite più piccole o man mano che l’ampiezza della ferita si riduce, il prodotto può essere aliquotato
e congelato per successive somministrazioni. Nel caso di paziente affetto da ulcerazione da
osteomielite occorre un lungo periodo di terapia antibiotica parenterale con Ampicillina-Sulbactam
o Piperacillina-Tazobactam o Ertapenem o Meropenem
associata a Vancomicina, oppure, alternativamente
Daptomicina. Discussione: in generale, la terapia deve essere
mirata sulla base dell’isolamento del germe patogeno, ma
spesso l’infezione è polimicrobica e quindi si somministra
una terapia empirica ad ampio spettro. Principio guida nella
terapia empirica è la somministrazione di antibiotici contro lo
Staphylococcus aureus meticillino resistente (MRSA). Nei
pazienti ambulatoriali è essenziale tenere in considerazione la
presenza di germi meticillino resistente associati alla
comunità di appartenenza (CA-MRSA) e quindi occorrono colture batteriche ripetute. Conclusioni:
l’approccio multidisciplinare tra chirurgo, immunotrasfusionista, infettivologo, dermatologo,
ortopedico, diabetologo e cardiologo, risolve brillantemente la problematica. Lo stretto
coordinamento tra ambulatorio chirurgico ed il centro trasfusionale, evita inutili attese al Paziente,
accorcia i tempi di esecuzione della medicazione, abbatte i costi per l’impiego di materiali e diventa
conveniente rispetto al trattamento tradizionale.Our study proves the usefulness of platelet gel in the treatment of the diabetic foot. We started in January 2006 to treat diabetic wounds of the foot in the outpatients’ surgical department with encouraging results. Despite its expensive and complex preparation, the platelet gel is useful and convenient because it succeeds in shortening the ambulatory treatment period. Besides, in our opinion, the multidisciplinary approach of this treatment is rather important: actually, it implies the cooperation of dermatologist, surgeon, orthopaedist, immunologist, diabetologist and, if necessary, the cardiologist. That is why it reduces wastes of work-time and the expenses for consultants, medications and dressing material
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
