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
Tongue Mucoceles: a retrospective clinic-pathological evaluation of 240 cases
No full textBackground: Minor salivary glands can be found in the ventral and anterior part of the tongue; these glands can rarely develop mucoceles that, due to their rarity and their unusual clinical appearance, may present an interesting differential diagnosis. Mucoceles appear as an exophytic, sometimes pedunculated, lesion, which is a feature that is due to the absence of a capsule; thus, the glands are right beneath the mucosa and over the muscle tissue. The aim of this article is to retrospectively present and discuss the anatomy, pathology, clinical features and therapy of several cases of Blandin-Nunh mucoceles collected from two different institutions. Methods: A retrospective case review was carried out in two university institutions, retrieving all cases of tongue mucoceles from 1999 to today. Two oral pathologists reviewed all the slides, confirming the diagnosis. Demographic data of the patient, anatomic location and clinical appearance were retrieved from clinical charts, together with the type of surgical procedure and possible relapses. Results: A total of 240 cases of tongue mucoceles were gathered from the archives: the mean age was 22 years (DS = 14,7; Range 2–83), 126 were females (52,5%, mean age 22,7 years, DS = 16,5; Range 2–83), and 114 were males (47,5%, mean age 20,9 years, DS = 12,4; Range 3–73); in all cases, a history of trauma was reported. The ventral surface was the most frequent location (224 cases – 93,3%), and in the great majority (235 cases – 97,9%), pathology revealed mucous spillage with a wall formed by fibrous connective and granulation tissue with no epithelium lining the cavity. Superficial mucocele and sclerosing sialoadenitis were the more frequent pathological variants (21 cases – 8,8%). All lesions were treated with excision and enucleation of the servicing gland. The healing was uneventful in all cases, but there were four recurrences and two cases of sensory paraesthesia of the border of the tongue, all in males, except one case of paraesthesia in a female. Conclusions: Tongue mucoceles must be differentiated from many benign and malignant lesions. For this reason, surgical removal of the lesion and of the associated gland with a pathological exam is mandatory. In fact, the anatomical location of the glands and the possible pathological variants must be considered to reach a correct diagnosis and diminish possible relapses.

Overview on osteoporosis, periodontitis and oral dysbiosis: The emerging role of oral microbiota
Full text linkOsteoporosis (OP) is a bone disease consisting of a progressive loss of bone mineral density (BMD) and therefore resulting in greater susceptibility to fractures. OP shares a number of risk factors and demographic characteristics with periodontitis (PD), a bacteria-induced chronic inflammation of periodontal structures that leads to loss of alveolar bone and teeth. In the last decade, with the advent of gut and oral microbiome studies and profiling, a growing diagnostic and prognostic significance has been attributed to dysbiosis associated with various systemic and organ-specific pathologies. This evidence has inspired research on modulating the microbiota to restore health by the use of prebiotics and probiotics. The aim of this work is to overview the bidirectional interrelationships between OP and PD, reporting the most recent evidence on triggering factors and, mainly, the role of gut and oral dysbiosis in the onset and progression of both OP and PD, with the perspective in their therapy
A Teacher-Configurable Scoring System for Serious Games
No full textSerious Games (SGs) are versatile tools that entertain while addressing serious issues through digital or analog gameplay. However, ensuring continuous supervision during gameplay can be challenging. To overcome this, we propose a flexible scoring system that automates procedure evaluation, empowering learners and promoting independent skill development. By conceptualizing procedures as ordered actions with specific information, our approach enriches the learning experience, making SGs more effective educational instruments. This research advances SGs, allowing students to take control of their learning journey and improving information retention through practical experiences. With this innovative scoring mechanism, SGs hold the promise of becoming even more impactful in addressing critical educational challenges
Sodium-hyaluronate mouthwash on radiotherapy-induced xerostomia: a randomised clinical trial
No full textIntroduction Radiotherapy-induced xerostomia (RIX) is one of the most common adverse effects of radiotherapy (RT) in head and neck cancer patients (HNC) and a major determinant of survivors' quality of life. The primary objective was to evaluate the reduction of patients' xerostomia symptoms after the utilisation of a sodium-hyaluronate mouthwash compared to a placebo solution. The secondary objectives were to evaluate the improvement of quality of life and to evaluate the patients' satisfaction.Methods The protocol was approved by the ethical committee (Ref. 50,053/19) and registered at ClinicalTrials.gov (ID: NCT05103124). The study was a double-blind randomised clinical trial (RCT) with a crossover design and was conducted at the Fondazione Policlinico Universitario A. Gemelli, Rome.Results Thirty-two patients completed the study protocol. Lower values of the modified Xerostomia Questionnaire (XQ) were retrieved when comparing the baseline scores to the ones after the treatment, when compared with placebo (Mann-Whitney U test = 0.01); higher values of patients' satisfaction (Likert scale) and modified XQ were retrieved for the sodium-hyaluronate mouthwash (Mann-Whitney U test = 0.001).ConclusionsThis RCT highlights the advantages of treating RIX with the sodium-hyaluronate mouthwash since it seems to be clinically effective in reducing its symptoms, without any reported adverse events.ClinicalTrials.gov: NCT05103124 in 17/10/2021.Conclusions This RCT highlights the advantages of treating RIX with the sodium-hyaluronate mouthwash since it seems to be clinically effective in reducing its symptoms, without any reported adverse events.ClinicalTrials.gov: NCT05103124 in 17/10/2021
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
Oral juvenile xanthogranuloma: An unusual presentation in an adult patient and a systematic analysis of published cases
No full textObjective. The purpose of this study was to describe an unusual case of intraoral juvenile xanthogranuloma (JXG) and to perform a systematic review to investigate the available literature regarding oral JXGs. Study design. We present a new case of oral JXG arising in a 36-year-old Italian woman and conducted a systematic literature review in PubMed, Web of Science, and Scopus, according to the PRISMA guidelines. Results. Our review of the English-language literature yielded 34 cases of oral JXG, which included our case report. Conclusions. JXG is a non-Langerhans cell histiocytosis. Oral JXG has been reported, but it is a rare manifestation. Because of the rarity of oral lesions and possible variations in the clinical and histologic presentation, the correct diagnosis can be challenging, requiring a careful clinical and histopathologic evaluation with adjuvant immunohistochemical studies
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
The association between periodontitis and sleep duration
No full textAIM:
Due to its potential to influence systemic inflammation and oxidative stress, and to predispose to bacterial infections, sleep duration could potentially be a risk factor for periodontitis. The aim of this cross-sectional study was to evaluate if there was in 2012 an association between periodontitis and sleep duration in a representative sample of the South Korean population.
MATERIALS AND METHODS:
A total of 5812 subjects representative of 39.4 million of adults were examined. Multivariate logistic regressions were applied controlling for age, gender, education, smoking status, alcoholism and consumption frequency of coffee, tea, chocolate and red wine.
RESULTS:
Compared to the group sleeping ≤5 h/day, the adjusted odds ratios for periodontitis prevalence defined as Community Periodontal Index (CPI) = 4 were OR = 2.46 (95% CI: 1.20-5.06) in the 6 h/day sleepers group, OR = 2.66 (95% CI: 1.35-5.25) in the 7 h/day sleepers group, OR = 2.29 (95% CI: 1.13-4.63) in the 8 h/day sleepers group and OR = 4.27 (95% CI: 1.83-9.97) in the ≥9 h/day sleepers group. The association has shown to be highlighted in middle-aged people, females, non-smokers, lower educated, with lower lead and higher cadmium blood levels and with higher carotene dietary intake ones and to be partially mediated by lipid profile alterations, diabetes, serum Vitamin D levels and WBC count.
CONCLUSIONS:
A novel, direct and independent association between sleep duration and the prevalence of periodontitis was found. However, it needs to be investigated how the factors influencing the sleep duration affect this association
