IMPAIRED ORAL HEALTH-RELATED QUALITY OF LIFE IN INDIVIDUALS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE: A SYSTEMATIC REVIEW
No full textBackground: Chronic obstructive pulmonary disease (COPD) has been associated with various health implications, including potential effects on oral health and Oral Health-Related Quality of Life (OHRQoL). Understanding the relationship between COPD and dental health is crucial for optimizing patient care and well-being. This review aims to assess the existing literature on the impact of COPD on oral health and OHRQoL. Methods: The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search was conducted in the databases, resulting in 304 records. Data extraction was done by 2 reviewers separately. Data extraction variables included study ID, sample, age, gender ratio, type of study, respiratory evaluation, OHRQoL assessment, and inferences. Newcastle Ottawa scale was employed to assess the methodological quality of the included studies. Results: The final selection included 3 studies eligible for qualitative synthesis. OHIP-5 and OHIP-14 were used to assess OHRQoL These studies provided valuable insights into the association between COPD and dental health. OHRQoL was negatively impacted among COPD sufferers. In addition, COPD patients demonstrated significantly fewer teeth and higher plaque index (PI) as compared to control cohorts. The risk of bias was low in the included studies. But the literature available was scarce, which warrants further longitudinal studies with a larger sample size in this regard. Conclusion: The evidence from the selected studies suggests a significant association between COPD and various dental health parameters, as well as their impact on OHRQoL. Dental health assessments should be integrated into COPD management to better understand disease severity and exacerbation risk. An interdisciplinary approach involving both respiratory and oral health professionals is crucial for comprehensive patient care. Future research should explore the underlying mechanisms and conduct longitudinal studies to establish causal relationships. These findings contribute to our understanding of the complex interplay between COPD and oral health and have implications for improving patient outcomes and quality of life
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
Variations 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
Craniofacial Morphology in Children With Obesity or Down Syndrome With and Without Obstructive Sleep Apnea
No full textIntroduction: Obstructive Sleep Apnea (OSA) is common in children. Risk factors include adenotonsillar hypertrophy, obesity, and craniofacial abnormalities (e.g. Down Syndrome, DS). The aim was to describe the craniofacial morphology in children with suspected OSA referred for polysomnography (PSG) in 2 cohorts: DS and obesity.
Methods: Cross-sectional study of children with DS or obesity referred for PSG at SickKids, Toronto. Orthodontic examinations, PSG, lateral cephalograms, and sleep questionnaires were completed.
Results: 42 children (20 DS, 22 obese) aged 5-18 (11.9 +3.6) were included. DS with OSA (Obstructive-Apnea-Hypopnea-Index (OAHI) >1) had increased palatal depth (p=0.04); OAHI was correlated with intercanine distance (r=0.48, p=0.03). ANB angle was increased in Obesity with OSA (p=0.03); OAHI was correlated with ANB (r=0.58, pM.Sc
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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

Dentofacial Morphology in Obese and Non-obese Children with and without Obstructive Sleep Apnea
Get PDFIntroduction: Several craniofacial abnormalities have been suggested to contribute to obstructive sleep apnea. These characteristics vary significantly among the literature and are limited by the infrequent use of polysomnogprahy, the gold standard for diagnosing and quantifying obstructive sleep apnea.
Objective: To compare the prevalence of facial and/or dental imbalances in children with and without obstructive sleep apnea in cohorts of obese and non-obese children.
Methods: A prospective, cross-sectional study of children (ages 4-16) who were referred for a polysomnogram at The Hospital for SickKids. Facial features and malocclusion was assessed clinically by one dentist, blinded to the PSG results.
Results/Conclusions: Horizontal excess (overjet) was the only dentofacial finding which was significantly more common in children with obstructive sleep apnea as compared to those without obstructive sleep apnea (p=0.04). Dentofacial characteristics were also not different between children using positive airway pressure therapy and children not on positive airway pressure therapyM.Sc

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
