Intraoperative indocyanine green imaging as an adjunctive technique to reduce any circumflex artery damage during mitral valve surgery: a feasibility study
No full text: Iatrogenic injuries to the circumflex coronary artery during mitral valve surgery are probably underestimated (reported rates of 0.3-1.8%). This complication arises from the artery's close proximity to the mitral annulus, particularly at the anterolateral commissure. The study aimed to assess this risk in a patient group prone to such injury. The surgical procedure utilized a minimally invasive approach and indocyanine green-based fluorescence imaging. This technique allows a real-time visualization of the circumflex artery, aiding precise placement of annular sutures and minimizing the risk of injury. The method, applied in 6 patients, integrates preoperative assessments with intraoperative fluorescence imaging, ensuring accurate arterial depiction and preventing iatrogenic damage. The study highlights the safety and efficacy of fluorescence imaging, especially in identifying vessel anomalies, indicating potential applications in various cardiac procedures
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
Infective endocarditis and litigation for compensation on healthcare-associated infections: An Italian sample analysis
Full text linkBackground: Litigation related to Healthcare-Associated Infections (HAIs) in Italy represent a growing field of interest in establishing the medico-legal link between infection and the healthcare environment and practices for compensation; it is little explored in the cardiovascular surgery regarding infective endocarditis (IE). Methods: We retrospectively analysed the civil judgements on infective endocarditis in the Italian region Emilia-Romagna from 2016 to July 2024 using Ministry of Justice national official database. The search was conducted on the online database on July 31, 2024, using the free word "endocarditis”. Two authors independently analysed the full-text judgements:, those IE without relevance in the reason for the claim were excluded. Main items were the timeline and outcome, with complaint motivation and liability ascertainment. In-court confirmation of healthcare causal link was reported. Results: Twenty-five judgments were retrieved. After screening for inclusion, nineteen judgements (11 of first instance and 8 of appeal) were included, for overall 15 cases of infective endocarditis. Of the fifteen cases, median age 60.5 years, 73 % males, median time for claim 6 years, for judgement 10 years and, if appealed, 16.5 years. Annual distribution of the claims was linear over time. Eleven (67 %) infective endocarditis were confirmed as healthcare-associated in trial. The prevalent reason for liability was improper or delayed diagnosis and/or treatment of the IE. Valvular surgery resulted in 40 %, while the more frequent pathogens were Staphylococcus aureus (40 %) and epidermidis (30 %). Of fifteen cases, 73 % was decided in favour of the patient-claimant, with an average cost of €289.872, plus an additional €55.296 in case of appeal. Only in 25 % the appeal's judge changed decision. In all cases, technical advisors were appointed. Conclusions: This sample provides an initial insight into litigation for compensation related to infective endocarditis, highlighting specific characteristics compared to HAIs management in court. Medico-legal reasoning should be integrated into infection prevention and control policies and overall clinical risk management strategies
Litigation in Cardiovascular Surgery: Risk Management Considerations in the Italian Context
Full text linkBackground/Objectives: Malpractice in cardiovascular surgery was addressed from the forensic pathology perspective, offering reflections on risk prevention in the Italian context. Litigation and risk management in healthcare, following the Italian law on safety of care, clinical risk management and professional liability, should be viewed in an integrated manner. Methods: We conducted a narrative review on litigation data and the principal areas of complaint in Italy regarding the cardiovascular field. The aim is to discuss human, communicative, organisational, technological and regulatory factors that may play a role in this phenomenon. Results: We discuss the importance of information and consent and the management and monitoring of competences, particularly in specialised activities, given the current human capital deficit. Furthermore, we focus on the centrality of the surgical indication focusing on benefit-risk balance in light of clinical guidelines and team-based evaluation, such as by an emergency heart team, to better tailor care to patients. At the facility level, the minimum volume of activity and the requirements for human resources, specialisations, technologies and organisation standards needed for health activity authorisation are highlighted as foundational to risk prevention. Furthermore, we discussed the availability of the minimum diagnostic and care tools in compliance with guidelines and the role of company clinical and organisational protocols. Conclusions: In the surgical, time-sensitive, highly specialised and technologically advanced sector, the importance of enterprise risk prevention and broad, value-based governance to ensure healthcare quality and safety is emphasised
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
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
