Importance of serum anticholinergic activity in the assessment of elderly patients with delirium
No full textTo evaluate the importance of serum anticholinergic activity (SAA) in elderly patients who developed delirium following hospital admission, we performed a cross-sectional study with consecutively referred inpatients in a university geriatric medical ward. Sixty-one patients aged 66 to 95 years (mean age: 79.2 +/- 11.6; 54% females) were recruited. Delirium was assessed by means of the Confusion Assessment Method, SAA determination, questionnaire for current drug treatment, past medical history and clinical examination, and blood chemistries. Patients were divided into two groups according to the absence (N = 49) or the presence (N = 12) of delirium. Delirious patients showed a significantly higher SAA(23.0 vs 3.9 pmol/mL atropine equivalents, P < .004); they were using antibiotics (P < .05), neuroleptics (P < .002), barbiturates (P < .004), and benzodiazepines (P < .005) more frequently. Subjects with delirium were more likely to have infections and a lower Body Mass Index; they had higher plasma glucose and creatinine. The multivariate analysis identified SAA and use of neuroleptics, and benzodiazepines as the most important features independently associated with delirium. SAA may be a suitable marker for identifying people at risk of developing delirium. Moreover, neuroleptics and benzodiazepines must be carefully used in the elderly because of their relationship with the onset of delirium.To evaluate the importance of serum anticholinergic activity (SAA) in elderly patients who developed delirium following hospital admission, we performed a cross-sectional study with consecutively referred inpatients in a university geriatric medical ward.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

No full textVariations on the Author
Get PDF“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
