Urban Spread of Flaviviruses: A New Challenge in Solid-organ Transplant Recipients
No full textYellow fever has never previously been reported in transplant recipients. The first reported case of yellow fever in a kidney transplant recipient in Brazil and the re-emergence of arboviruses in many areas of the world dictate the need of studies aimed to answer multiple unanswered questions
Continuous peripheral nerve blocks: state of the art
No full textPurpose of review: This review was performed through a Medline research to evaluate articles published between January 2004 and April 2005. Technical procedures, indications, drugs, infusion regimens, and complications of continuous peripheral nerve blocks were considered. Recent findings: A total of 27 articles were reviewed. With respect to technical procedures, the authors focused on advantages of stimulating catheters or ultrasound guidance. With the help of these techniques, a correct catheter placement as close to the targeted nerve as possible was obtained. The total amount of local anesthetic administered was thereby reduced. Using ultrasound needle guidance, the spread of local anesthetic around the nerve could be visualized. Articles dealing with the choice of local anesthetic showed equianalgesia and equipotency of continuous perineural infusion of levobupivacaine 0.125% and ropivacaine 0.2%. The best infusion regimen for postoperative analgesia appears to be a combination of a preset basal rate administered together with small bolus doses in almost all continuous peripheral nerve blocks. Overall, complications such as infections, local anesthetic toxic plasma levels, hematoma formation, or nerve injury seem to be rare in continuous peripheral nerve blockade. Summary: Continuous peripheral nerve blockade is an effective and safe technique for postoperative analgesia, even when administered at home. To optimize this technique, further studies are needed to help minimize the risk of side effects, improve techniques to locate the targeted nerve (stimulating catheters or ultrasound imaging) and choose less toxic drugs (levobupivacaine and ropivacaine) with more effective infusion regimens

Recent advances in cytomegalovirus infection management in solid organ transplant recipients
Full text linkPurpose of review Human cytomegalovirus (CMV) continues to be the most important infectious complication following solid organ transplantation (SOT). Recent findings Universal prophylaxis and preemptive therapy are the most adopted strategies for prevention of CMV disease globally. Prophylaxis with valganciclovir is the most widely used approach to CMV prevention, however leukopenia and late onset CMV disease after discontinuation of prophylaxis requires new strategies to prevent this complication. The use of assays detecting CMV-specific T cell-mediated immunity may individualize the duration of antiviral prophylaxis after transplantation. Letermovir has been recently approved for prophylaxis in kidney transplant recipients. CMV-RNAemia used together with CMV-DNAemia in the viral surveillance of CMV infection provides accurate information on viral load kinetics, mostly in patients receiving letermovir prophylaxis/therapy. The development of refractory and resistant CMV infection remains a major challenge and a new treatment with maribavir is currently available. In the present paper we will review the most recent advances in prevention and treatment of CMV diseases in SOT recipients. Summary Recent findings, summarized in the present paper, may be useful to optimize prevention and treatment of CMV infection in SOT
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
