No full textTotal intravenous anesthesia and the new parameter for administering the most recent drugs, target-controlled infusion, as well as the introduction of new short half-life molecules that do not accumulate have made anesthesia in day surgery safer. In this study, the use of auditory-evoked potentials monitoring made it possible to determine the target plasma concentration of propofol that induces a narcosis sufficiently deep and strictly necessary for effectiveness, thus minimizing the anesthesiologic risk linked to the use and the dosing of the drug, reducing the hospitalization time, and decreasing the side effects for patients undergoing day surgery mammoplasty.Total intravenous anesthesia and the new parameter for administering the most recent drugs, target-controlled infusion, as well as the introduction of new short half-life molecules that do not accumulate have made anesthesia in day surgery safer.

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
Role of a digital tool in preoperative lung resection surgery assessment
No full textThe assessment of patients likely to undergo lung resection surgery is a multidisciplinary approach involving pulmonologists, surgeons and anaesthesiologists. In thoracic surgery, medical operability is also a calculation of postoperative lung function. A mobile application – PreParAPP MSD – to calculate postoperative lung function has been developed with the endorsement of the Italian Society of Anaesthesia, Analgesia and Intensive Care and with the unconditional support of MSD Italia. Thanks to a simple graphic interface, the calculation becomes fast and intuitive, while the possibility of storing and sharing data in an analytical and computerised way with other clinicians might help with the full assessment of patients without forcing them to undergo several medical examinations. These simple calculated parameters are performed by a minority of clinicians, generally anaesthesiologists. In our facility, there is a team involved in the perioperative evaluation of lung resection surgery (13 pulmonologists, 9 surgeons and 5 anaesthesiologists). In order to evaluate the possible Awareness towards postoperative lung function calculation better, we organised an internal survey with 27 clinicians who are members of such a team before and after the introduction of the PreParAPP MSD. It was found that after the introduction of PreParAPP MSD, the percentage of clinicians involved in postoperative lung function calculation rose from 18% to 70%. The implementation of a digital tool may help to improve guideline adherence, in accordance with other experiences in which such tools represented the start for various quality improvement purposes throughout the medical field
