Prevalence and Management of Complications of Laser Ablation for Benign Thyroid Nodules
No full textContext Percutaneous laser ablation (LA) is today regarded as a valuable therapy for symptomatic, benign solid (noncystic) thyroid nodules (STNs).Objective We assessed the prevalence of complications from LA for benign and STNs and their management.Methods We conducted a systematic review with meta-analysis of data from published studies on LA of STNs, in addition to author institutions. A random effects meta-analysis was performed on the prevalence rates.Results The literature search yielded 1351 studies, of which 38 studies were included, in addition to our institutional experience (4745 STNs in total). The overall quality of each included study was judged as fair. The prevalence of "overall" complications of LA was 23% ([CI, 17%-30%], I2 93.7%, 1208 of 4702 thyroid nodules [TNs]). The prevalence of "minor" complications of LA was 21% ([CI, 15%-27%], I2 93.7%, 1159 of 4702 TNs). The prevalence of "major" complications of LA was 2% ([CI, 1%-3%], I2 54.0%, 49 of 4745 TNs). Sensitivity analyses did not modify the results, except for dysphonia, whose pooled prevalence was higher when using local anesthesia (2%; CI, [1%-3%], I2 25.2; P = .010) or conscious sedation (2%; CI, [1%-4%], I2 27.2; P = .014). The pooled prevalence rate of local pain was 15% (CI, [12%-20%], I2 89.3). Local pain was transient and typically mild to moderate, sometimes severe, requiring analgesics for 1 to 5 days up to 1 month. The pooled prevalence rate of dysphonia was 2% (CI, [1%-2%], I2 30.3). All cases of dysphonia were transient except for one permanent case.Conclusion LA for benign and noncystic STNs can be considered a generally safe technique. Major complications are rare
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
Unilateral Graves' disease: a case report with concomitant thyroid cancer and systematic review of literature
No full textINTRODUCTION: Unilateral uptake (i.e., increased radiotracer in one lobe) on a thyroid scan in a patient with Graves' disease (GD) is the distinctive feature of unilateral GD (UGD), representing a rare entity and variant of GD with few documented cases to date. Considering the diagnostic and therapeutical implications of the knowledge of this form of GD, this study was designed to bring more light on the UGD entity within the bilobar thyroid gland. EVIDENCE ACQUISITION: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in reporting this systematic review. We developed a search strategy combining terms for Graves or Hyperthyroidism and unilateral systematically and searched PubMed from inception through August 25, 2024. The inclusion criteria were: 1) patients with Graves' hyperthyroidism due to a unilateral involvement in bilobar thyroid gland; 2) articles written in English or any language with an English abstract. EVIDENCE SYNTHESIS: A total of 10 articles met inclusion criteria, in addition to our institutional experience (comprising 27 individual patients in total). All the included studies were case reports/series. Of the 27 patient cases, 20 (74.1%) were female and the mean age of patients was 44.5 +/- 10.6 years. 24 patients (88.9%) had overt hyperthyroidism, two (7.4%) subclinical hyperthyroidism, one (3.7%) had initially normal thyroid function. Orbitopathy was present in two cases out of ten (20%). thyrotropin receptor antibodies (TRAb) or thyroid stimulating immunoglobulin (TSI) were positive in 9 cases out of 12 (75%). Right thyroid lobe was involved in 17 cases (63.0%), while the left one in 10 cases (37.0%). Antithyroid drugs ATDs were adopted by 13 patients (68.4%). Four patients (21.1%) underwent surgery, while radioactive iodine (RAI) was performed in two cases. Two cases (15.4%) received a 12-month course of ATD therapy, one of whom recurred. In two out of three cases after hemithyroidectomy hyperthyroidism recurred due to the involvement of the contralateral lobe of the thyroid gland. CONCLUSIONS: Clinicians should be aware of the possibility that GD can present in the bilobar thyroid gland with unilateral gland involvement at scintigraphy. Ultrasound examination is indicated to detect the presence of contralateral thyroid tissue, and to exclude the possibility of a hyperfunctioning nodule or hemiagenesis. When choosing surgery, total thyroidectomy seems to be the appropriate treatment. Further investigation is needed to determine the natural course of UGD and its best management. Future guidelines should consider this form of GD
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
