Central venous catheter insertion in peripheral blood hematopoietic stem cell sibling donors: The SIdEM (Italian Society of Hemapheresis and Cell Manipulation) point of view
No full textCollection of peripheral blood hematopoietic stem cells (PBSC) is the practice of choice for graft procurement in both autologous and allogeneic setting. The success of this procedure depends on the use of adequate vascular accesses. Well-sized peripheral veins are the first option in autologous and allogeneic donations. In autologous setting, in case of lack of adequate veins, central venous catheters (CVC) may be used for collection. In the allogeneic setting, although available data have shown the safety of the use of CVC, there are still some controversies about the possible insertion of a CVC in donors. A specific policy from competent registries is usually applied in the different countries to regulate the use of CVC in unrelated donors. In siblings, the question is still undefined due both to the lack of shared guidelines and to the specific characteristics of this donation. In fact, in not so rare cases, larger stem cell doses for specific cell manipulations (e.g., T/B cell depletion in the haploidentical setting) are needed. The lack of international rules or standard that forbid the use of a CVC in siblings and published data that document the safety of this procedure, allowed the Societa Italiana di Emaferesi e Manipolazione Cellulare (SIdEM) national Board to identify a possible, shared, operational approach to address this issue by a case-specific risk-benefit assessment.

Dismembrement: a review of the literature and descriprion of 3 cases.
No full textThe authors describe 3 cases of dismemberment. Numerous methods of hiding a body and thus erasing proof of murder have been devised. Those most frequently described in the literature include: burial of the body in an unusual or impervious place such as a wood, grotto or mountain; charring the body by wrapping it in a tire, for example, to fuel the fire until all traces of the crime have been erased and identification of the victim is difficult; and dropping the weighted-down body in the open sea or in a well in the hope that it will never be found. Dismemberment is in reality a relatively rare method whereby, after killing the victim, the murderer uses a very sharp cutting weapon (a saw, axe, etc.) to sever the limbs and cut the body into small pieces. The operation is generally carried out immediately after the crime, although more rarely a long time may pass between the 2 events.

Other, less frequent methods include dissolving the body in acid or burying it in cement; for example, under the pylons on the motorway or the foundations of a house being built

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
