Valutazioni odontoiatriche in bambini e adolescenti obesi
No full textSCOPO DEL LAVORO
L’analisi del campione ha come scopo l’indagine di un’eventuale correlazione tra obesità infantile e adolescenziale e sviluppo di malocclusioni di tipo scheletrico o dentale e la valutazione dell’influenza del fattore obesità nell’insorgenza di disturbi respiratori.
MATERIALI E METODI
Il campione preso in esame è formato di 20 pazienti facenti parte della fascia d’età tra i 10 e i 16 anni e con un BMI>20 kg/m2. I dati sono stati raccolti mediante esame clinico e compilazione del questionario RDC-TMD, a cui sono state aggiunte valutazioni sul tipo di respirazione e rilevazioni ortodontiche. I test prevedevano l’utilizzo di un calibro di precisione e di un kit prima visita (specchietto, pinzetta, sonda) e i dati sono stati inseriti in un database informatico.
RISULTATI
I risultati mostrano una respirazione di tipo nasale nell’80% dei casi; dal punto di vista anatomico è rilevante il riscontro di un palato ogivale nel 55% dei casi e ortodonticamente è stata notata una Classe molare di tipo II nel 30% dei casi e una Classe canina di tipo II nel 40% del campione. Un quarto dei pazienti rivelava la presenza di morso incrociato. Le analisi sui disturbi temporomandibolari risultano negative nella quasi totalità dei casi, mostrando anzi un’elasticità articolare superiore allo standard nei movimenti di apertura attiva e assistita.
CONCLUSIONI
Lo studio conferma quanto rilevato dalla revisione della letteratura, appurando l’assenza di TMD in età giovanile ma mostrando malocclusioni, specie di Classe II nel campione preso in esame. Il tipo di respirazione appare nella norma, nonostante si possano notare lievi anomalie anatomiche di sviluppo.AIM OF THE WORK
The aim of this study was to evaluate a possible correlation between obesity in childhood and adolescence and skeletal or dental malocclusions, and to investigate the influence of obesity on the onset of breathing disorders.
MATERIALS AND METHODS
The sample was composed of 20 patients aged ranging from 10 to 16 years old and having a BMI >20Kg/m2. Data were collected through clinical examination and RDC-TMD questionnaire, adding breathing and orthodontic evaluations. Clinical examinations were performed using caliper, dental probe, mirror and tweezers; data were recorded in an electronic database.
RESULTS
The evaluations showed nasal breathing in 80% of sample; anatomically the ogival palate was detected in 55% of cases; orthodontically a II molar Class was detected in 30% and a II canine Class in 40% of the sample. One fourth of the children examined showed cross bite. TMD test resulted negative in almost all cases, showing interestingly a more flexible joint than standard during active and assisted opening movement.
CONCLUSION
The study confirms the findings reported in the literature about the absence of TMD in young age but showing malocclusion, particularly of Class II in the sample examined. The type of breathing is normal, although it may be noted light developmental anatomical anomalies
Physical activity levels across COVID-19 outbreak in youngsters of Northwestern Lombardy
No full textBACKGROUND: Italy early experienced one of the most suffering impact of the COVID-19 outbreak in terms of number of cases and death toll. Progressively, more compelling national restrictions hardened citizens' lifestyle and habits, including limiting mobility and outdoor physical activity (PA ). In a second phase, people were allowed to perform outdoor activities close to their houses and thereafter motor or sports activity were gradually reintroduced. These drastic changes raised the question on how to cope and exploit the residual oppor tunities of PA under circumstances of home confinement. METHODS: International Physical Activity Questionnaires were administered to 1568 youngsters from North-western Italian high schools, before, during, and after lockdown enacted by Italian Government to contrast the COVID-19 pandemic. RESULTS: Student's PA levels were significantly different before (1676.37±20.6 MET-min/week) and after (1774.50±33.93 MET-min/week) the governmental restrictions (TIME effect: F=3.49; ηp2=0.005 P=0.03). There was a significant TIME∗CATEGORY interaction effect (F=8.37; ηp2=0.021; P<0.001). In particular, only highly active students (>2520 MET-min/week) increased their PA during (3467.48±55.85 MET-min/ week) and after (3515.73±65.75 MET-min/week) the lockdown measures with respect to their baseline levels (3151.43±42.41 MET-min/week). CONCLUSIONS: Lockdown measures, including isolation, impacted negatively on the PA levels of the already inactive or moderately active young population. Government actions should enhance strategies to control physical inactivity during pandemics like COVID-19
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
