Major Amputation In Non-Healing Ulcers: Outcomes and Economic Issues. Data from a Cohort of Patients with Diabetic Foot Ulcers
No full text: Background: Foot ulcers have a relevant economic impact on Health Care Systems and the cost-effectivenesseffectiveness of options is not clear. The aim of this study was the assessment of costs for ulcers treatment after 6, 12, and 18 months of follow-up, compared to those for major amputation. Methods: A retrospective study was carried out on 196 types 2 diabetic patients with foot ulcers. The principal endpoints were 1) the proportion of recovered patients among those with ulcers not healed after 6 and 12 months; 2) the assessment of direct costs for treatment of ulcers 6, 12, and 18 months of follow-up, as compared to the cost of major amputation. The economic evaluation was performed considering the perspective of the local health system. Results: Out of 196 patients, 85(46.2%), 131(71.6%), and 140(85.9%) healed within 6, 12, and 18 months, respectively. The average health cost during the 18-month follow-up was 5402€ per patient. We calculated hypothetical costs for three different scenarios, in which patients who did not heal within 6 months underwent a major amputation at 6, 1,2, or 18 months. Costs for the standard of care for all these scenarios (6,094, 7,256, and 7649€ for 6, 12, or 18 months, respectively) were significantly lower than that for major amputations (21,065€). Conclusions: A conservative approach appears more convenient than major amputations in ulcers not healing after 6 months, irrespective of the estimated risk of individual patients
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
Project Financing nel Settore Sanitario: Un'Analisi della Gestione dei Servizi Non Core presso l'Ospedale San Luca di Lucca
No full textTitolo: Il Project Financing nel Settore Ospedaliero: Un'Analisi sulla Gestione dei Servizi Non Core
Abstract:
Il presente studio propone un'analisi esaustiva sull'impiego del project financing nel settore ospedaliero, con particolare attenzione alla gestione dei servizi non core. Il project financing, come strumento di finanziamento di grandi progetti infrastrutturali, è stato ampiamente adottato nel contesto sanitario per affrontare le sfide di modernizzazione e ampliamento delle strutture ospedaliere. Tuttavia, la gestione dei servizi non core all'interno di questi progetti rappresenta un aspetto critico spesso trascurato nelle analisi convenzionali. Attraverso uno studio approfondito della letteratura e l'analisi di casi studio empirici, questo lavoro esplora le dinamiche gestionali, le sfide e le best practices associate alla gestione dei servizi non core nei progetti di project financing ospedaliero. Le dimensioni strategiche, manageriali e di controllo vengono esaminate allo scopo di identificare i fattori chiave di successo e fornire raccomandazioni pratiche per migliorare l'efficienza e l'efficacia della gestione dei servizi non core all'interno di progetti di project financing nel settore ospedaliero
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
Adherence to and early adverse events of COVID-19 vaccine in a cohort of 600 Italian breastfeeding and pregnant physicians
Full text linkPregnant and breastfeeding women (PBW) have been excluded from COVID-19 vaccine registry and the majority of post-marketing trials, despite the recognized increased risk of severe infections and complications. The lack of efficacy and safety data prevented the formulation of specific indications/guidelines for vaccination and could have also contributed to increased vaccine hesitancy (VH) in PBW. The aim of this cross-sectional study is to assess the rate and predictors of VH, and early adverse events (AEFI) following COVID-19 vaccine in PBW with a cross-sectional study. In January 2021, a purposely designed questionnaire was administered to 600 PBW part of a Facebook group of physicians, immunized with two doses of Comirnaty®. Thirty-eight (29%) pregnant women and 13 (2.8%) breastfeeders were hesitant. The only statistically significant negative predictor of COVID-19 VH appeared to be having had the flu shot in 2020/2021 (OR: 0.35; 95% CI: 0.13–0.97; p = .044). Approximately 27% of PBW reported hesitancy toward the 2020/2021 season influenza vaccine. Among the vaccinated subjects, 51.6% of pregnant and 75.2% of breastfeeding women reported at least one symptom after the first, and 82.4% and 81.6%, respectively, after the second dose. Nausea/vomiting, fatigue, headache and arthralgia/myalgia were the most common symptoms; dizziness, shivering, syncope and limb paresthesia were rarely reported. Among infants of breastfeeding mothers, six experienced fever, five rash and four moderate and self-limiting diarrhea. Preliminary data on mRNA COVID-19 vaccine in PBW and in their infants are reassuring since AEFI, although frequent, are typically mild and similar to those occurring in the general population, and in PBW after other vaccines. Larger studies with longer follow-up after vaccination are strongly recommended to develop recommendations in these patients
