    Aim. To evaluate long-term results of anti-reflux surgery. Objectives. 1. To assess the failure rate of repeated anti-reflux surgery. 2. To determine patients‘ persistent symptoms and satisfaction with surgery after refundoplication. 3. To assess the influence of laparoscopic fundoplication technique and use of surgical mesh on the results of repeated anti-reflux surgery. Methods. Study was performed using Visick scale, to evaluate the following symptoms: heartburn, difficulty swallowing, bloating, regurgitation. Scales from 1 to 5 were used to assess the intensity of symptoms. Based on Visick severity scores, surgery method and use of mesh influence on treatment results was determined. Statistical analysis was performed using SPSS program. Student “t“ test was used to compare means with normal data distribution and nonparametric test for nonnormal distribution. Mann-Whitney “U“ test was used to used to determine difference in medians. Fisher‘s exact test was employed when size samples were small (<30). The findings were considered statistically significant when p-value < 0,05. Study participants. Patients who underwent re-operative hiatal hernia surgery at Hospital of LSMU „Kauno Klinikos“ from 2002 to 2018. Results. Study sample consisted of 58 patients who underwent revisional operations for failed fundoplication at Hospital of LSMU „Kauno Klinikos“ from 2002 to 2018. 14 (24,1%) were suspected of hiatal hernia recurrence regarding the intensity of symptoms on Visick scale. 6 (10,3%) patients were confirmed with hiatal hernia recurrence. The most common symptoms after surgery were gas bloating and heartburn, wheres dysphagia and regurgitation were less frequent. Majority of patients were satisfied with the results of the operation. Different reoperative fundoplication methods and use of mesh provided no significant benefit regarding recurrence rate. Conclusions. Reoperative antireflux surgery is safe and effective long-term treatment method for recurrent hiatal hernia with a recurrence rate of 10.3%. Heartburn and bloating were the most common symptoms after refundoplication. Majority of patients are satisfied with the results of the operation. Reoperative fundoplication method and use of mesh provided no significant benefit regarding recurrence rate

    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

    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

    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

    Aim.&nbsp;To evaluate and compare effectivenes of sacral and posterior tibial nerve stimulation for treating fecal incontinence.Methods.&nbsp;Systematic literature review was performed to compare sacral and posterior tibial nerve stimulation effectiveness. Research was performed in “Medline” database, using the “PubMed” website. English or lithuanian articles, published between 2008 and 2019, were included in our study. Results were described to assess the effect of interventions in each analysed article. We included 7 articles into meta-analysis. Articles compared the effectiveness of sacral or posterior tibial nerve stimulation with control groups or other treatment methods for managing fecal incontinence. Cochrane guidelines were used to perform this meta-analysis.&nbsp;Results.&nbsp;The results of meta-analysis suggests that sacral neuromodulation is superior to posterior tibial nerve stimulation to treat fecal incontinence compared to control groups or other treatments. Literature also suggest that after comparing these methods directly, sacral neuromodulation is superior to treat fecal incontinence a.&nbsp;Conclusion.&nbsp;Sacral neuromodulation is superior posterior tibial nerve stimulation to treat temporary or chronical fecal incontinence than and can be used as an alternative for surgical interventions.Tikslas.&nbsp;Įvertinti ir palyginti kryžkaulio nervų ir užpakalinio blauzdinio nervo stimuliacijos efektyvumą išmatų nelaikymui gydyti.&nbsp;Tyrimo metodai.&nbsp;Siekiant palyginti kryžkaulio nervų neuromoduliacijos (KNM) ir užpakalinio blauzdinio nervo stimuliacijos (TNS) efektyvumą, atlikta sisteminė literatūros apžvalga.

    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

    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
