Outpatient paediatric hand surgery: strategy in healthcare implementation and cost-efficient manner
No full textThe increasingly cost of health care is a relevant problem as well as prolonged waiting time for admission also in emergencies. Effective cost containment measures and expenditure controls are needed to achieve and maintain clinical and organizational appropriateness. Outpatient management has proven to be the most useful method for lower-cost treatment in less severe pathologies, requiring surgery without hospitalization. The current study provided to evaluate how this model was successfully applied also to the paediatric population in hand surgery. Methods. A retrospective cohort study of 645 patients from 8 to 18 years (mean age 14.9) was performed in children treated in outpatient setting from 2015 to 2019. The direct costs were evaluated as well as the mean waiting time for surgery, comparing the data with the previous five-year period. The mean reduction in waiting time for children emergencies was 57% (from 72 to 31 h) due to the Outpatient setting into a dedicated Day-Surgery Service organizational model. The visual graphed data showed a general clear growing trend towards outpatient surgery in adults and children. The overall effect was a 29.2% of reduction in spending between expected and achieved costs, recovering resources toward the increasing technology and innovation expenditures. Outpatient paediatric hand surgery was an effective and attractive option which leaded to decreased individual and social costs, with increased clinical and organizational appropriateness. Thus, reduced delay in treatment and provided benefits for children and familiars.The increasingly cost of health care is a relevant problem as well as prolonged waiting time for admission also in emergencies.

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
Custom-Made Total Talonavicular Replacement in a Professional Rock Climber
No full textProfessional athletes are often eager to resume sporting activities at preinjury levels. When facing the challenge of restoring joint function after a complex articular fracture, innovative solutions must be explored. We describe the results of what we believe to be the first custom-made talonavicular prosthesis implanted in a professional rock climber who had developed post-traumatic ankle and talonavicular arthritis as sequelae of a complex talar and navicular fracture. Using computed tomography scan reconstruction of the contralateral healthy ankle and direct metal laser sintering, a custom-made talonavicular prosthesis was obtained and implanted using an anteromedial approach. The patient was clinically and radiographically evaluated every 6 months after surgery for 30months. A 3-dimensional videofluoroscopic analysis was performed to assess the range of motion about the prosthesis. At the last follow-up visit, the functional scores were excellent (Tegner activity scale score of 9 of 10), and he had completely resumed his sporting activity. The American Orthopaedic Foot and Ankle Society score had increased from 36 to 81 points, and no signs of radiolucency were observed on the radiographs. The 3-dimensional videofluoroscopic analysis showed 15° of dorsiflexion and 4° of plantar flexion at the ankle. A customized solution is an option when the patient's expectations are not likely to be met by standard treatment, such as arthrodesis. A custom-made talonavicular prosthesis can be an effective solution for complex ankle injury sequelae in patients demanding high functionality
Regenerative treatment in osteochondral lesions of the talus: autologous chondrocyte implantation versus one-step bone marrow derived cells transplantation
No full textPurpose Osteochondral lesions of the talus (OLT) usually require surgical treatment. Regenerative techniques for hyaline cartilage restoration, like autologous chondrocytes implantation (ACI) or bone marrow derived cells transplantation (BMDCT), should be preferred. The aim of this work is comparing two clusters with OLT, treated with ACI or BMDCT.Methods Eighty patients were treated with regenerative techniques, 40 with ACI and 40 with BMDCT. The two groups were homogenous regarding age, lesion size and depth, previous surgeries, etiology of the lesion, subchondral bone graft, final follow-up and pre-operative AOFAS score. The two procedures were performed arthroscopically. The scaffold was a hyaluronic acid membrane in all the cases, loaded with previously cultured chondrocytes (ACI) or with bone marrow concentrated cells, harvested in the same surgical session (BMDCT). All the patients were clinically and radiologically evaluated, using MRI Mocart score and T2 mapping sequence.Results Clinical results were similar in both groups at 48 months. No statistically significant influence was reported after evaluation of all the pre-operative parameters. The rate of return to sport activity showed slightly better results for BMDCT than ACI. MRI Mocart score was similar in both groups. MRI T2 mapping evaluation highlighted a higher presence of hyaline like values in the BMDCT group, and lower incidence of fibrocartilage as well.Conclusions To date, ACI and BMDCT showed to be effective regenerative techniques for the treatment of OLT. BMDCT could be preferred over ACI for the single step procedure, patients' discomfort and lower costs
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
