No full textAfter the rapid acceptance of laparoscopy to manage multiple benign diseases arising from gastrointestinal districts, some surgeons started to treat malignancies by the same way. However, if the limits of laparoscopy for benign diseases are mainly represented by technical issues, oncologic outcomes remain the foundation of any procedures to cure malignancies. Cancerous patients represent an important group with peculiar aspects including reduced survival expectancy, worsened quality of life due to surgery itself and adjuvant therapies, and challenging psychological impact. All these issues could, potentially, receive a better management with a laparoscopic surgical approach. In order to confirm such aspects, similarly to testing the newest weapons (surgical or pharmacologic) against cancer, long-term follow-up is always recommendable to assess the real benefits in terms of overall survival, cancer-free survival and quality of life. Furthermore, it seems of crucial importance that surgeons will be correctly trained in specific oncologic principles of surgical oncology as well as in modern miniinvasive technologies. Therefore, laparoscopic treatment of gastrointestinal malignancies requires more caution and deep analysis of published evidences, as compared to those achieved for inflammatory bowel diseases, gastroesophageal reflux disease or diverticular disease. This review tries to examine the evidence available to date for the use of laparoscopy and robotics in malignancies arising from the gastrointestinal district
Robot-Assisted Pancreatic Surgery: Safety and Feasibility.
No full textThe recent advent of robotic surgery has changed the surgical perspective in operating theatres worldwide. The main innovation is that a computer-based interface, located between patient and surgeon, is able to improve his/her dexterity. The goal of robotic surgery is, therefore, to reduce intraoperative complications, overcome some limits of pure laparoscopy, and, definitively, reduce the postoperative impact of surgery on the patients. A shorter hospital stay is expected to reduce the interval between access to adjuvant therapies when dealing with oncologic diseases, leading to a potential survival increase. Nevertheless, the broad clinical application of robotics to pancreatic surgery has many peculiarities. The intrinsic difficulties of this kind of surgery, the lack of specific expertise (pancreatic surgery and robotic skills), together with the need for regional centralization are the major drawbacks. However, robotic surgery has been demonstrated to be safe and feasible in pancreaticoduodenectomy, distal pancreatectomy (with or without spleen preservation), enucleation, and atypical resections

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
