External jugular vein approach for TIVAD implantation: first choice or only an alternative? A review of the literature.
No full textPURPOSE:
Totally implantable venous access devices (TIVADs) can be implanted by percutaneous approach (to the subclavian or internal jugular vein) or by surgical approach, through cephalic vein or external jugular vein (EJV). The authors present a review of the literature about EJV approach for TIVAD implantation.
METHODS:
A review of articles indexed in MEDLINE (PubMed) and Cochrane Central Register on "EJV access," "EJV cut-down," and "TIVADs" was performed, even matching the terms.We gathered articles from papers quoting patient number, specialist involved, number of devices implanted, site and technique of implantation and complications.
RESULTS:
A total of 1,308 TIVAD implantations through EJV have been reported, with a success rate ranging from 73.7% to 100% and a complication rate up to 13%. Only in 4 on 10 series reported (with more than 15 procedures) the EJV approach was the first choice, while in the other 6 series this approach was the alternative after failure of other approaches.
CONCLUSIONS:
Despite the lack of consistent series and prospective studies comparing EJV with other approaches, data present in the literature may support the evidence that EJV approach for TIVAD implantation is safe and effective, and may be considered as the first approach in selected patients
Azimuthal separation in nearly back-to-back jet topologies in inclusive 2- and 3-jet events in pp collisions at √s=13Te
No full textA measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, Δφ12 , is presented. The measurement considers events where the two leading jets are nearly collinear ("back-to-back") in the transverse plane and is performed for several ranges of the leading jet transverse momentum. Proton-proton collision data collected with the CMS experiment at a center-of-mass energy of 13Te and corresponding to an integrated luminosity of 35.9fb-1 are used. Predictions based on calculations using matrix elements at leading-order and next-to-leading-order accuracy in perturbative quantum chromodynamics supplemented with leading-log parton showers and hadronization are generally in agreement with the measurements. Discrepancies between the measurement and theoretical predictions are as large as 15%, mainly in the region 177∘<180∘ . The 2- and 3-jet measurements are not simultaneously described by any of models
O amor como ágape na práxis social. Origem, definição e perspectivas
No full textO objetivo do artigo é a definição de amor na sua dimensão agápica. Decorrente do debate em curso na teoria crítica sociológica entre Frankfurt e Paris, que é a obra de Luc Boltanski (2004) e Axel Honneth (2002), o artigo atinge a uma conceituação original. Ao reconstruir sua genealogia cultural, que remonta à sociologia da religião de Weber, que, em seguida, é realçada na diferença entre o amor do tipo ideal e da dádiva ideal. Finalmente, o amor agápico é relatado como um conceito útil para interpretar a formação de uma subjetividade individual não angustiada
Sconfini dell'educazione. Quando irrompono emozioni violente nel lavoro educativo
No full textAi margini della mente vigile, ai margini della città ben organizzata, ai margini del mondo agiato esistono dolorose realtà: quella dei giovani disorientati che non sanno o non possono progettare il proprio futuro, quella degli emarginati che vivono cronicamente nei ghetti e nell’illegalità, quella dei poveri del mondo che sono esclusi o sfruttati dall’economia globale. In questi territori, percorsi da violente emozioni, dove la ragione e la parola sono precarie e il vivere civile incerto e difficile, l’educazione è luogo di possibile speranza. Il paradigma pedagogico ereditato dalla scuola di Comenio sembra funzionare solo per coloro che vivono già una vita civile, che hanno accesso alla parola e dimestichezza con la cultura razionale. Occorre allora un paradigma pedagogico nuovo, che dia voce a chi non ce l’ha, che allenti le maglie della paura e dell’odio, riaprendo la fiducia nel futuro: un paradigma che utilizzi pratiche che sconfinano dal consueto, avvalendosi dei dispositivi psicologici volti a sostenere la riflessività e la cura di sé, dell’altro e delle relazioni. La scuola comunitaria va oltre il concetto di riproduzione della società per perseguire la sua rifondazione: in quest’ottica essa diventa luogo di frontiera per eccellenza e quindi realtà che attiva cittadinanza per le nuove generazioni e non solo per i giovani a rischio di emarginazione
Variations on the Author
No full text“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

ARGENTINA: Río Negro: Atlantic coast, easternmost kilometer of the colony (41 º 3 ’ S, 62 º 48 ’ W) (Masello & Quillfeldt 2004 b); 3 km west of the mouth of the Río Negro River, 30 km southeast of Viedma (41 º 04’ S, 62 º 50 ’ W) (Masello et al. 2006 a). Further explorations are needed for determining if Cyanolicimex patagonicus is restricted to the type-locality and/or only to the subspecies Cyanoliseus patagonus patagonus. This is the southernmost known limit of the Haematosiphoninae in the Western Hemisphere (Fig. 1), and the third Haematosiphoninae with a Psittacidae bird as a host. Etymology. Specific epithet refers to the Argentinean region where this species was found (Fig. 1). Bionomics of the host and Cyanolicimex patagonicus. The cimicid bugs live inside crevices along the face of the sandstone cliff where the Burrowing Parrots dig their burrows. From there, they access the burrows of the parrots and their breeding chambers. During the first years of bug collection (1999, 2001, 2003, 2004), the numbers of bugs were not quantified, but they were very high around all nests of the study sector at the Burrowing Parrot colony (for details and precise location of the study sector see Masello & Quillfeldt 2002, 2004a). In contrast, the cimicid bug was very scarce in the same parrot colony during December, 2009 (Masello pers. obs.). The summer 2009–2010 was very hot and dry, and the collected specimens died soon after they were extracted from the crevices and burrows. The entire sequence of a breeding season of Cyanoliseus patagonus at El Cóndor (Masello & Quillfeldt 2002, 2004a 2008, Masello et al. 2006) can be, on average, summarized as follows. 1) Return of the migrating birds to the colony: August-September. 2) Copulations: September–October. 3) Incubation of the eggs: October–November. 4) Hatching of the nestlings: end of October through the end of November. 5) Nestling period: end of October through the end of January. 6) Fledgling: end of December through the end of January. 7) Migration (partial): February–March. Therefore, the feeding period of C. patagonicus is restricted when the burrows are occupied by the parrots, i.e., from August −September through the end of January (fledgling of the nestlings). As the breeding pairs spend the night inside the nests during the nestling period (Masello et al. 2006 c), both nestlings and adults can be food sources for C. patagonicus. After this, the bugs are deprived of food for at least 6 months (from February through the end of July). In this way, the bionomics of C. patagonicus are similar to other species of Cimicidae from the nests of swallows in the Northern Hemisphere [Oeciacus vicarius Horvath, 1912 from North America, and Oeciacus hirundinis (Lamark, 1816) from Europe]. Where colonies are reoccupied each year, the three-month breeding period of the cliff swallow Petrochelidon pyrrhonota (Vieillot, 1817) [Aves: Hirundinidae] limits its specialized ectoparasite, O. vicarius, to a short feeding period before host migration, and a food resource deprivation that lasts nine months (Loye 1985). Semi-collapsed and abandoned burrows of C. patagonus are also used by other bird species for nesting. Nevertheless, there are only few records in the literature (Appendix II), probably because of the inaccessibility of the places chosen by the Burrowing Parrots. Observations by one of the authors (J.F.M.) permit the addition of new records (Appendix II). These other bird species may be potential hosts of C. patagonicus, especially if some of them use the burrows for roosting during autumn and winter. Noteworthily, the geographically-distant species Rhynchopsitta pachyrhyncha (Swainson, 1827) [Aves: Psittacidae] from Mexico has a similar-associated ectoparasitic fauna (Table 2). The nests of R. pachyrhyncha are made inside natural cavities or by using old woodpecker holes, forming high-density clusters of nesting pairs sharing nest trees, with a maximum of three nesting pairs per tree. Clusters contained a mean of 11.5 breeding pairs [5 nests/ha]. Thirty-three (68 %) from a total of 48 monitored nest trees were reused for at least 2 nesting seasons; a mean annual reuse was 62 ± 0.08 % nest trees [range 56–71 %] (Monterrubio-Rico et al. 2006). In contrast, Myiopsitta monachus (Boddaert, 1873) [Aves: Psittacidae] is a nonmigratory Psittacidae, that uses its nest year-round for roosting and breeding (Navarro et al. 1992). In this way, the food sources of Psitticimex uritui (Lent & Abalos, 1946) [Hemiptera: Cimicidae] are available all the time. The nests of M. monachus from western and northern Argentina are also colonized by great numbers of Argas monachus Keirans, Radovsky, & Clifford, 1973 [Acari: Argasidae], exclusively specific to this parrot (Turienzo & Di Iorio pers. obs.).

Vocação para o chão: inespecificidade e queda na poesia de Maria Isabel Iorio
No full textA partir de poemas do livro Aos outros só atiro o meu corpo (2019), o artigo apresenta uma leitura da produção da artista Maria Isabel Iorio em diálogo com o conceito de inespecificidade na arte, desenvolvido por Florencia Garramuño. Para localizar o movimento da queda e a presença do chão na poesia da autora, o texto utiliza como referência o teórico e dramaturgista da dança André Lepecki. Além disso, propõe que mesmo na inespecificidade há espaço para a singularidade, destacando vestígios de uma experiência sapatão em constante disputa e transformação
