Perché una lezione di cardiologia agli psichiatri e di psichiatria ai cardiologi?
No full textLe interazioni tra i farmaci psichiatrici e cardiologici devono richiamare l’attenzione sia dello psichiatra che del cardiologo. Ad esempio possiamo citare le più note interazioni:
• Beta-bloccanti con fenotiazine /SSRI= Ipotensione e cardiotossicità
• Ca-antagonisti e BDZ= Prolungata sedazione
• Ca-antagonisti e litio= Tossicità da litio
• Clonidina e fenotiazine= Ipotensione e Delirium
• Diuretici e litio= tossicità
• Warfarin e carbamazepina= Riduzione del livello di Warfarin
• Warfarin e alcuni SSRI= Aumento o riduzione dell’attività del Warfarin
• Così come molti farmaci psichiatrici antisicotici, antidepressivi, stabilizzanti dell’umore hanno influenza sul funzionamento cardiaco che deve essere sempre monitorato prima della prescrizione.
• La Depressione presenta anche molte comorbilità con le malattia cardiologiche da cui deriva con:
• Amplificazione dei sintomi somatici
• Minore aderenza al trattamento della malattia organica
• Peggiore prognosi
• Aumento del ricorso alle strutture sanitarie
Vengono illustrati diversi casi clinici paradigmatici, tra cui:
Donna di 48 anni che riferisce ansia. Assume BDZ cronicamente per problemi di insonnia e a volte sintomatologia ansiosa acuta
In PS manifesta i seguenti sintomi:
Dispnea
Fame d’aria
Oppressione precordiale
Tachicardia
Tremori
Paura di morire.
Viene posta diagnosi di attacco di panico, soprattutto a causa dell’assunzione di farmaci psichiatrici e richiesta la consulenza psichiatrica. Il tracciato ECG richiesto poi insieme allo psichiatra dimostrerà che era in atto un infarto miocardico acuto.
L’attenzione che deve essere posta sulla diagnosi differenziale è evidentemente di estrema importanza. La discussione dei diversi casi permetterà di illustrarne la significatività clinica
Late Cenozoic tectono‐stratigraphic sequences of the Crotone Basin: insights on the geodynamic history of the Calabrian arc and Tyrrhenian Sea
No full textThe Crotone Basin was generated in the late Cenozoic as a forearc basin of the Ionian arc-trench system. New data are gained through detailed field mapping, high-resolution stratigraphic analysis of a key area and examination of offshore well data and seismic reflection profiles. Major unconformities divide the basin fill into major sequences, which reveal a three-stage internal organization thought to reflect geodynamic events of the Calabrian arc and backarc area closely. The first stage is characterized by extensional block faulting and uplift followed by rapid drowning during high subsidence and transtension in the basin along a major NNW- to NW-striking fault system. This stage is interpreted to reflect resumption of rollback after an episode of slab tearing triggered by transitory docking of continental lithosphere in the trench. The initial uplift is inferred to reflect decoupling and rebound after the transitory coupling phase. The second stage is characterized by increased subsidence and continued extension/transtension. This trend presumably reflects a decreasing rate of rollback resulting from a tendency towards viscous coupling after acceleration of slab downwelling. The third stage is characterized by short-lived transpression along major shear zones and local inversion of former basins. This is inferred to reflect entrance into the trench of buoyant continental lithosphere, resulting in significant deceleration of slab rollback and consequently a break in, or slowing of, backarc extension, and predominance of the effects of compression related to Africa–Europe convergence. Overall, the above evolution resulted in the formation of a progressively narrower and rapidly retreating slab, inducing extreme rates of backarc extension, and may have played a critical role in determining the intermittent nature of the backarc rifting
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Sedimentology, palynostratigraphy and sequence stratigraphy of a continental to shallow marine rift-related succession: Upper Permian of the eastern Southern Alps (Italy)
No full textThe Upper Permian deposits (Val Gardena Sandstones) of the eastern Southern Alps display the typical features of early rift succession onset of sedimentation after a long period of subaerial erosion, and upward fining trend from red beds through evaporites to marine carbonates
