Άγχος και κατάθλιψη ασθενών με αναφερόμενο θωρακικό άλγος μη καρδιακής αιτιολογίας
No full textΕισαγωγή: Το θωρακικό άλγος αποτελεί ένα από τα συχνότερα αίτια αναζήτησης υπηρεσιών υγείας. Σε πολλές περιπτώσεις το θωρακικό άλγος είναι μη καρδιακής αιτιολογίας και σχετίζεται με την ύπαρξη ψυχοπαθολογίας. Σκοπός: Η εκτίμηση των επιπέδων άγχους και κατάθλιψης ασθενών που προσέρχονται στο ΤΕΠ με αναφερόμενο θωρακικό άλγος μη καρδιακής αιτιολογίας. Υλικό και Μέθοδος: Η μελέτη ήταν συγχρονική και συμμετείχαν 56 ασθενείς με θωρακικό άλγος μη καρδιακής αιτιολογίας, οι οποίοι προσήλθαν στο ΤΕΠ γενικού νοσοκομείου της Αττικής από το Δεκέμβριο του 2017 έως και τον Απρίλιο του 2018. Η εκτίμηση του άγχους και της κατάθλιψης των ασθενών έγινε με τη χρήση της κλίμακας HADS. Η στατιστική ανάλυση περιελάμβανε έλεγχο Mann-Whitney, το έλεγχο Kruskal-Wallis και το συντελεστή συσχέτισης του Spearman. Το αμφίπλευρο επίπεδο στατιστικής σημαντικότητας ορίστηκε στο 0,05. Η ανάλυση των δεδομένων πραγματοποιήθηκε με το IBM SPSS 20.0. Αποτελέσματα: Η μέση ηλικία των ασθενών ήταν 44,4 (±15,4) έτη, με την πλειοψηφία (58,9%) να είναι άντρες. Η βαθμολογία της υποκλίμακας άγχους (HADS-Α) έδειξε ότι 55,3% των ασθενών εμφάνιζαν άγχος, ενώ από την υποκλίμακα της κατάθλιψης (HADS-D) φάνηκε ότι 44,6% είχαν κατάθλιψη. Ως προς τη βαρύτητα των συμπτωμάτων, η πλειοψηφία των συμμετεχόντων είχε μέτρια συμπτωματολογία για το άγχος (25%) και ήπια για την 69 κατάθλιψη (23,2%). Η ύπαρξη άγχους σχετίστηκε θετικά, σε στατιστικά σημαντικό βαθμό, με το γυναικείο φύλο (p=0,002), το χρονικό διάστημα από την πρώτη εμφάνιση του θωρακικού άλγους (p=0,001) και τον αριθμό των επισκέψεων στο Τ.Ε.Π για θωρακικό άλγος το τελευταίο έτος (p=0,004). Αντίθετα, βρέθηκε αρνητική σχέση με το ύψος (p<0,013) και το βάρος (p=0,048). Αναφορικά με την κατάθλιψη προέκυψε στατιστικά σημαντική θετική σχέση με το γυναικείο φύλο (p=0,002), το χρονικό διάστημα από την πρώτη εμφάνιση του θωρακικού άλγους (p<0,001), τον αριθμό των επισκέψεων στο Τ.Ε.Π (p<0,001) και τον αριθμό των παιδιών (p=0,014). Αντίθετα, βρέθηκε αρνητική σχέση με το ύψος (p<0,001) και το βάρος (p=0,036). Συμπεράσματα: Περίπου οι μισοί ασθενείς που προσέρχονται στο ΤΕΠ με θωρακικό άλγος μη καρδιακής αιτιολογίας εμφανίζουν άγχος ή κατάθλιψη. Οι επαγγελματίες υγείας, ανάμεσά τους και οι νοσηλευτές, οφείλουν να λαμβάνουν σοβαρά υπόψη τους τη πιθανότητα ύπαρξης ψυχοπαθολογίας σε αυτούς τους ασθενείς και να διενεργούν τον ενδεδειγμένο διαγνωστικό έλεγχο, ώστε να αποφασίζεται η κατάλληλη θεραπευτική αγωγή.Introduction: Chest pain is one of the most common causes for the usage of health services. In many cases chest pain is non-cardiac and it is related to the existence of psychopathology. Aim: The assessment of the levels of anxiety and depression of patients who visit Emergency Department (ED) with reported non-cardiac chest pain. Material and Methods: The study was cross-sectional and involved 56 patients with non-cardiac chest pain, who arrived at the ED of a General Hospital of Attica, from December 2017 to April 2018. Patient’s anxiety and depression were estimated by the use of HADS scale. The statistical analysis included Mann-Whitney test, Kruskal-Wallis test, and Spearman's correlation coefficient. The two-sided level of statistical significance was set at 0.05. Data analysis was performed with IBM SPSS 20.0. Results: The mean age of patients was 44.4 (±15.4) years, with the majority of them (58.9%) being men. The anxiety score (HADS-A) showed that 55.3% of the patients had anxiety, while the depression subscale (HADS-D) showed that 44.6% were depressed. Concerning the severity of the symptoms, the majority of participants had moderate symptoms for anxiety (25%) and mild for depression (23.2%). Anxiety was significantly associated with female gender (p=0.002), time from the first appearance of chest pain (p=0.001) and the number of visits to the ED for chest pain during the last year (p=0.004). Also, a negative relationship 71 was found with height (p<0.013) and weight (p=0.048). Regarding depression, a statistically significant positive relationship came up with the female sex (p = 0.002), the time from the first occurrence of chest pain (p <0.001), the number of visits to the ED during the last year (p <0.001) and the number of children (p=0.014). In contrast, height (p <0.001) and weight (p=0.036) were negatively correlated with depression. Conclusions: Approximately half of patients who visit ED with chest pain of non-cardiac etiology develop anxiety or depression. Healthcare professionals, nurses among them, should seriously consider the possibility of psychopathology in these patients and carry out the appropriate diagnostic tests to determine the appropriate treatment
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
