Exposure to vehicular traffic is associated to a higher risk of hospitalization for bronchiolitis during the first year of life
No full textBACKGROUND: The most common cause of hospitalization for children younger than age one is bronchiolitis. Several prenatal and environmental risk factors may affect the incidence of hospitalization for bronchiolitis. The aim of this study was to investigate the relation between exposure to vehicular traffic and the incidence of hospitalization for bronchiolitis in children during their first year of life in Italy. METHODS: A multicenter prospective birth cohort study, where equal numbers of newborns of 33-34, 35-37 and .38 wGA were recruited at birth (1814 children) in 30 Italian neonatology units. Two interviewer-administered questionnaires were used to collect data. The first interview was carried out at the end of the Italian epidemic season. The second interview was carried out when the child was one year old. Data on possible prenatal, perinatal, and postnatal/environmental risk factors and on vehicular traffic density in the zone of residence were collected. On each interview, parents were also asked about any hospitalizations of the child. The outcome measure was the hospitalization for bronchiolitis (International Health Service ICD-9 code 466). RESULTS: Univariate analysis demonstrated that exposure to air pollution due to vehicular traffic, was significantly associated with an increased risk of hospitalization for bronchiolitis. The adjusted risk from logistic regression model confirmed that children exposed to air pollution due to vehicular traffic were at increased risk of hospitalization for bronchiolitis. CONCLUSIONS: Exposure to air pollution due to vehicular traffic may increase the risk of hospitalization for bronchiolitis in the first year of life
Delirium in nursing home residents: is there a role of antidepressants? A cross sectional study
No full textBackground Delirium is strongly associated with poor health outcomes, yet it is frequently underdiagnosed. Limited research on delirium has been conducted in Nursing Homes (NHs). Our aim is to assess delirium prevalence and its associated factors, in particular pharmacological prescription, in this care setting. Methods Data from the Italian "Delirium Day" 2016 Edition, a national multicenter point-prevalence study on patients aged 65 and older were analyzed to examine the associations between the prevalence of delirium and its subtypes with demographics and information about medical history and pharmacological treatment. Delirium was assessed using the Assessment test for delirium and cognitive impairment (4AT). Motor subtype was evaluated using the Delirium Motor Subtype Scale (DMSS). Results 955 residents, from 32 Italian NHs with a mean age of 84.72 +/- 7.78 years were included. According to the 4AT, delirium was present in 260 (27.2%) NHs residents, mainly hyperactive (35.4%) or mixed subtypes (20.7%). Antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with lower delirium prevalence in univariate and multivariate analyses. Conclusions The high prevalence of delirium in NHs highlights the need to systematically assess its occurrence in this care settings. The inverse association between SSRIs and delirium might imply a possible preventive role of this class of therapeutic agents against delirium in NHs, yet further studies are warranted to ascertain any causal relationship between SSRIs intake and reduced delirium incidence
Virtual environments for cognitive and physical training in elderly with mild cognitive impairment: A pilot study
No full textThis work aims at providing an evaluation of the acceptability and the usability of a virtual reality-based intervention developed for the physical and cognitive training of mild cognitive impaired elderlies. To perform this evaluation, participants enrolled in the intervention group (n = 4) of a randomized controlled trial to test the system were interviewed, and their adherence and their performances in the virtual environments for cognitive training were evaluated. In spite of the small sample, the active participation and the unanimous positive judgement of all the participants led to the conclusion that the training program was well accepted and enjoyable. Participants also claimed reduced level of anxiety in their ADL. On the basis of these encouraging results, a second trial, with enlarged sample and with a system implementing the improvements required to overcome the limitations and the problems highlighted with this pilot study, will be performed in the next future
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
