    Endometriosis and bowel comorbidities

    No full text
    Endometriosis is an estrogen-dependent gynecological condition characterized by the presence and growth of ectopic endometrial tissue, often associated with inflammation, severe and chronic pain, and infertility. Lesions are categorized as superficial peritoneal lesions, endometriomas, or deep infiltrating nodules, with high degree of individual variability in lesion color, size, and morphology. Numerous factors involved in this disease, including inflammation, angiogenesis, cytokine/chemokine expression, and endocrine alterations such as steroid and steroid receptor expression. When endometrial-like glands and stroma infiltrate the bowel wall, reaching at least the subserous fat tissue or the adjacent subserous plexus, the condition is diagnosed as intestinal endometriosis. Matherial and methods The aim of this study is to analyze the bowel comorbidities of the endometriosis. In particular, the frequency of endometriosis in young women with abdominal pain and to evaluate the most feared complication after surgery. In the first time, we consider the young fertile age women with right iliac fossa (RIF) pain . This is one of the most common complaint in those presenting at the emergency department and requiring acute care. A group of fertile age women (18-45 years) undergoing emergency surgery for acute RIF pain According to the intraoperative and pathology findings, patients were subdivided into 2 groups: group A was composed by those with histological diagnosis of endometriosis, whereas group B identified the controls. During the surgery, peritoneal samples were taken and analized. The present study showed that in women undergoing appendectomy for a RIF pain, superficial peritoneal endometriosis (SUP) is an incidental diagnosis in 23% of cases. In the second time, we consider the bowel endometriosis. When endometriosis infiltrate the bowel wall, reaching at least the subserous fat tissue or the adjacent subserous plexus, the condition is diagnosed as intestinal endometriosis Medical treatments include nonsteroidal anti-inflammatory drugs, oral contraceptives, progesterone, and gonadotropin-releasing hormone. Instead, surgical treatment includes shaving or resection. We performed this study with the aim of identifying the number of leaks in colonic resections for deep endometriosis. Conclusions Endometriosis is a very common condition in fertile young women. Knowing the degree of infiltration and deciding on the best treatment strategy should not be undervalued

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Treatment of median incisional hernia. Laparoscopic vs. open surgery: meta-analysis

    No full text
    In the last ten years we assisted to spreading of laparoscopic approach on the correction of median incisional hernia, although for increased interesting toward mini-invasive techniques than for matching results between lap and open approaches. The aim of our study is the critical analysis of the results of lap and open surgery in the approach of ventral hernia, through the meta-analytical revision of the principal checked prospective trials. There were emerged 7 perspective studies to fit to a meta-analysis with the revision of the literature, with 1165 patients in total. Among the perioperative outcomes the briefer surgical time and a reduction of postoperative hospitalization were observed with the significant statistic data in favor of the lap. Laparoscopy can be considered a valid technical alternative to traditional open surgery in the treatment of ventral incisional hernia. The advantages of mini-invasive approach are the reducing of the surgical time and of the total hospital stay. There were not emerged any significant differences regarding the other surgical end-points or the recurrences of hernias after 1 and 5 years

    Variations on the Author

    “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 link
    We 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 link
    We 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 text
    We 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
