    The role of probiotics in preventing dental caries: a systematic review of clinical evidence

    No full text
    Background: Probiotics have emerged as a promising adjunctive strategy for oral health, particularly in the prevention of dental caries, a multifactorial disease driven by ecological imbalances in the oral microbiome. Methods: A systematic search of PubMed, Scopus, and Web of Science was conducted for studies published between January 2014 and January 2025, focusing on the use of probiotics for caries prevention in children and young adults. Clinical trials and observational studies were included, and a qualitative synthesis was performed based on the extracted outcomes. Results: Twenty-one studies met the inclusion criteria. Most clinical trials reported a significant reduction in Streptococcus mutans levels following administration of probiotic strains, particularly Lactobacillus paracasei, Lactobacillus rhamnosus, and Bifidobacterium lactis. Several studies also demonstrated a decreased incidence of new carious lesions and an improvement in salivary immune markers. However, a minority of studies found no significant effect, highlighting potential variability due to strain type, dosage, delivery method, and population characteristics. Conclusion: The current evidence supports the potential of specific probiotic strains to reduce cariogenic bacterial loads and contribute to caries prevention. Further standardized, long-term trials are needed to clarify the most effective formulations and regimens for clinical application

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Imaging techniques for evaluating temporomandibular joint involvement in juvenile idiopathic arthritis: a systematic review

    Full text link
    Objective Juvenile idiopathic arthritis (JIA) encompasses a group of chronic inflammatory disorders affecting children and adolescents, characterized by persistent arthritis of unknown etiology. Its pathogenesis is multifactorial, involving genetic, environmental, and immunological factors. This systematic review evaluates current diagnostic approaches for detecting temporomandibular joint (TMJ) involvement in JIA. Materials and Methods Following PRISMA guidelines and registered in PROSPERO (CRD 529873), a comprehensive search was conducted in PubMed, Scopus, and Web of Science for studies published between January 1, 2013, and August 1, 2024. Search Terms Included (Imaging OR CBCT OR cone beam OR MRI OR ultrasound OR magnetic resonance imaging) AND (juvenile idiopathic arthritis OR JIA) AND (temporomandibular joint OR TMJ). Studies focusing on TMJ diagnostic techniques in JIA patients were included. Results Out of 528 records, 18 studies met the inclusion criteria. The results emphasize the critical role of advanced imaging—particularly magnetic resonance imaging (MRI), cone beam computed tomography (CBCT), and ultrasound (US)—in detecting early TMJ changes. While MRI remains the gold standard for evaluating soft tissue and inflammatory activity, CBCT and US offer complementary insights. The review highlights the need for standardized diagnostic protocols and further studies to refine imaging strategies and improve clinical outcomes in JIA

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    Advancing Postoperative Pain Management in Oral Cancer Patients: A Systematic Review

    Full text link
    The goal of this review is to shed light on the management of orofacial discomfort after a cancer diagnosis in the head and neck region. A search was conducted on PubMed, Scopus, and Web of Science to identify studies on postoperative pain control in oral cancer. The review included open-access research, investigations into pain management, randomized clinical trials, retrospective studies, case-control studies, prospective studies, English-written studies, and full-text publications. Exclusion criteria included animal studies; in vitro studies; off-topic studies; reviews, case reports, letters, or comments; and non-English language. Three reviewers independently accessed databases and assigned a quality rating to the chosen articles. The review explores postoperative pain management in oral cancer patients; highlighting persistent opioid use; the efficacy of adjuvant drugs, such as gabapentin; and a multimodal approach. It emphasizes the need for personalized pain management, recognizing individual pain perception and tailoring interventions. Integrating pharmacological and non-pharmacological strategies is crucial for comprehensive pain management. The review also serves as a guide for future research, emphasizing the need for standardized methodologies and diverse participant populations

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We 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
