Accuracy and safety of ChatGPT-4o responses in rhinoplasty postoperative counseling: a panel-based study
No full textBackgroundChatGPT and other large language models have emerged as new tools for patient education, yet their clinical safety and reliability remain unclear.ObjectiveTo assess the accuracy and safety of ChatGPT-4o's responses to common postoperative questions following rhinoplasty.MethodsTen consensus-based postoperative questions were identified via a modified Delphi process. ChatGPT-4o responses were generated and evaluated by three independent otolaryngologists using a 10-point Likert scale. Reviewers also assessed the presence of critical errors.ResultsThe average Likert score across responses was 8.87 (95% CI, 8.39 to 9.34), No critical errors were detected. Inter-rater reliability was high (ICC(2,k) = 0.876).ConclusionsChatGPT-4o provided clinically accurate and safe answers to common rhinoplasty postoperative questions.SignificanceThese findings suggest that ChatGPT-4o may serve as a useful adjunct for postoperative patient counseling in structured settings, particularly when physician access is limited
Evaluation of the Systemic Inflammation in Patients with Bell's Palsy: Monocyte-to-High-Density Lipoprotein Cholesterol Ratio and Hematologic Indices of Inflammation
Full text linkBackground: We aimed to investigate the prognostic significance of hematological inflammatory indices and monocyte-to-high-density lipoprotein cholesterol ratio (MHR) in the diagnosis and prognosis of Bell's palsy. Method: The study included 156 cases diagnosed with Bell's palsy in the neurology clinic and 156 healthy controls. The patients diagnosed with Bell's palsy were staged according to the House-Brackmann Scoring system. Hematological inflammatory parameters such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) levels, and MHR were calculated from the parameters in the patient files. Result: Hematological inflammatory parameters such as NLR, PLR, SII, SIRI, and MHR were found to be higher in Bell's palsy patients. In addition, these parameters were found to be higher in patients with grade V and above Bell's palsy and in patients who did not respond to treatment, compared to the grade IV group and patients who responded to treatment, respectively. SIRI was an independent predictor of both the diagnosis of the disease and the lack of response to treatment, and this was confirmed by LASSO analysis. Conclusions: This study is among the few that demonstrated predictive models based on hematological inflammatory indices that can aid in both the diagnosis and treatment response assessment of newly diagnosed Bell's palsy patients, validated using the LOOCV method. The findings highlight the potential clinical utility of simple, inexpensive, and practical biomarkers such as NLR, PLR, SII, SIRI, and MHR. These easily accessible parameters may support early diagnosis and prognostic evaluation in routine clinical settings
Predictive value of preoperative neutrophil-to-lymphocyte ratio for post-tonsillectomy hemorrhage: Age-specific insights from a pediatric cohort
No full textObjective: To evaluate the predictive value of preoperative neutrophil-to-lymphocyte ratio (NLR) for postoperative hemorrhage following pediatric tonsillectomy and to explore its age-specific performance. Methods: This retrospective study included 100 pediatric patients who underwent tonsillectomy at a single tertiary center between January 2021 and December 2025. Fifty patients with postoperative hemorrhage and 50 without bleeding were analyzed. Preoperative NLR values were compared between groups. Receiver operating characteristic (ROC) curve analysis and multivariate logistic regression were performed to assess the predictive capacity of NLR. Subgroup analysis was conducted for patients aged ≤7 years. Results: The bleeding group had significantly higher preoperative NLR values compared to controls (2.72 ± 2.21 vs. 1.79 ± 0.72, p = 0.023). ROC analysis yielded an AUC of 0.632 for all patients and 0.697 for those aged ≤7 years. An NLR threshold of 2.35 provided 40 % sensitivity and 86 % specificity for predicting hemorrhage, while an NLR cut-off of 2.08 improved sensitivity (64 %) and specificity (83 %) in younger children. Multivariate analysis confirmed NLR as an independent predictor of postoperative bleeding (OR = 1.68, p = 0.016). Conclusion: Elevated preoperative NLR is associated with an increased risk of postoperative hemorrhage after pediatric tonsillectomy, particularly in children aged ≤7 years. Preoperative NLR measurement may serve as a useful adjunct in perioperative risk stratification
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
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
