Interval Laparoscopic En-Bloc Resection of the Pelvis (L-EnBRP) in patients with stage IIIC-IV ovarian cancer: Description of the technique and surgical outcomes
No full textObjective To describe the technique and evaluate the feasibility, efficacy and morbidity of the Laparoscopic En-Bloc Resection of the Pelvis (L-EnBRP) during Visceral-Peritoneal Debulking (VPD) at time of interval surgery. Methods This report is part of a prospective non randomized study (service evaluation protocol) on the feasibility and safety of laparoscopy in patients with stage IIIC-IV ovarian cancer and gross residual disease following neoadjuvant chemotherapy. Primary endpoints of this part of the study were the feasibility (rate of patients in whom the surgery could be completed by laparoscopy), efficacy (rate of patients ended with a complete resection) and morbidity (number of patients that suffered complications specifically associated to the procedure) of L-EnBRP. The results were compared between patients in group 1 (L-EnBRP + L-VPD), group 2 (L-EnBRP + VPD) and group 3 (VPD). Results Eighteen patients were in group 1, 8 in group 2 and 32 in group 3. Feasibility of L-EnBRP was 45% (26 patients out of 58), efficacy was 100% of the pelvic disease (94.4% overall disease) and morbidity was 5.5%. Main cause for conversion to laparotomy was high tumor load on diaphragm and/or mesentery. All but one patient had a complete resection (CR) of the disease. Group 1 patients had significantly earlier hospital discharge, lower blood loss and reduced overall morbidity than group 2 and 3. Conclusion L-EnBRP was feasible in almost half of the patients. In these patients a CR was achieved with a low morbidity rate. The latter was significantly decreased when compared to the patients who had a laparotomy
Latest developments and techniques in gynaecological oncology surgery
No full textPurpose of review: To highlight the advances and the data published in the field of gynaecological oncology surgery in the last few years. The review includes not only newly introduced surgical techniques but also data that consolidate recent developments. Recent findings: Ultimate data on the use of laparoscopy in the treatment of gynaecologic malignancies have proven similar survival outcomes to the traditional surgical route and confirmed the benefits in terms of faster recovery and lower morbidity. Thanks to a faster learning curve, the use of robotic surgery has contributed to the increase in the number of surgeons who moved away from open surgery. A few pioneers are expanding the indications of laparoscopy to exenterative surgery and treatment of ovarian cancer. Summary: Laparoscopic surgery has become the gold standard treatment for patients with primary endometrial or cervical cancer. The advent of robotic surgery has reinforced the domain of endoscopic surgery
Feasibility of laparoscopic diaphragmatic peritonectomy during visceral-peritoneal debulking (Vpd) in patients with stage iiic-iv ovarian cancer
No full textObjective: To describe the surgical technique and evaluate the safety, feasibility and efficacy of laparoscopic diaphragmatic peritonectomy during Visceral-Peritoneal Debulking (VPD) in patients with stage IIIC-IV ovarian cancer (OC). Methods: This report is part of a Service Evaluation Protocol (Trust number 3267) on laparoscopy in patients with OC following neo-adjuvant chemotherapy. Between April 2015 and November 2017, all patients underwent to exploratory laparoscopy and a selected court was offered laparoscopic VPD. Laparoscopic diaphragmatic surgery was considered if there was no full thickness involvement. Primary endpoints of this part of the study were the safety, feasibility and efficacy of laparoscopic diaphragmatic peritonectomy. We report the surgical technique and outcomes. Results: Ninety-six patients underwent diaphragmatic surgery during the study period. Fifty patients (52.1%) had intra-operative exclusion criteria and/or full thickness diaphragmatic resection, 46 (47.9%) had peritonectomy and were included in the study. Laparoscopic diaphragmatic peritonectomy was performed in 21 patients (45.4%, group 1), while in 25 patients (54.6%, group 2) laparotomy was necessary. Extent of disease and complexity of surgery were similar. Reasons for conversions were disease coalescing the liver to the diaphragm preventing safe mobilization (22 patients) and accidental pleural opening (3 patients). Overall, intra-and post-operative morbidity was lower in group 1 and pulmonary specific morbidity was very low. Conclusion: Diaphragmatic peritonectomy can be safely accomplished by laparoscopy in almost half of the patients with OC whose disease is limited to the diaphragmatic peritoneum
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
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
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
