Infective Endocarditis Following Dental Procedures: A Retrospective Literature Review of Reported Cases and Clinical Outcomes
No full textInfective endocarditis (IE) remains a serious and potentially life-threatening complication associated with bacteremia following invasive dental procedures. Although preventive strategies exist, cases continue to be reported, particularly among individuals with known risk factors. This study aims to systematically review the reported cases and epidemiological evidence of IE following dental interventions. A retrospective literature review was conducted using studies indexed in PubMed that reported cases of IE following dental procedures. Three studies were included: two case reports detailing individual clinical outcomes, and one population-based observational study assessing post-procedural risk. Extracted data included patient demographics, type of dental procedure, time from procedure to infection onset, microbiological findings, risk factors, clinical management, and outcomes. Across all three studies, a clear correlation was observed between invasive dental procedures— particularly tooth extractions—and the onset of IE. The case reports identified patients with prosthetic heart valves and children with congenital heart disease as high-risk groups. Oral anaerobic flora, including Prevotella species, was implicated in cases involving prosthetic valves. The epidemiological study demonstrated a transient increase in IE incidence within 1–3 months following invasive dental treatments. Clinical outcomes ranged from full recovery with antibiotic therapy and surgical intervention, to significant morbidity in pediatric cases, despite prophylactic measures. Invasive dental procedures can precipitate infective endocarditis, especially in patients with pre-existing cardiac risk factors. Increased awareness of at-risk populations, stringent infection control, and adherence to prophylactic guidelines remain essential for prevention. Further population-based research is needed to better refine risk stratification and optimize prophylactic strategies
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
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
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
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

Clear Aligners and CAD/CAM Technology: A Digital Approach to Ortho-Prosthetic Treatment – Case Presentations
No full textThe rapid advancements in digital dentistry have paved the way for a more adequate and efficient approach to orthodontic–prosthetic treatment. The use of clear aligners in combination with CAD/CAM technology has transformed treatment planning, patient communication, and clinical management of cases requiring a multidisciplinary approach. This technology enables precise coordination between orthodontic tooth movements and the design of prosthetic restorations, ensuring optimal functional and aesthetic outcomes. Digitalization has facilitated the application of intraoral scanning, orthodontic treatment planning with aligner software, 3D printing, as well as the design and fabrication of prosthetic restorations using CAD/CAM technology. This paper presents clinical cases in which a standardized workflow was applied. Initially, a clinical examination was conducted to assess the case, followed by orthodontic treatment with clear aligners. Upon achieving the final orthodontic outcome (controlled tooth or arch movements), the workflow continued with prosthetic rehabilitation, where high-quality aesthetic zirconia crowns and bridges were fabricated. Based on the treated clinical cases, we can conclude that the integration of digital technology has ensured very accurate treatment, superior functional and aesthetic outcomes
