L’architecture de l’information dans le discours scientifique

As the title suggests, we would like to study a peculiarity of the mathematical scientific discourse, namely the informational organization. Our theoretical framework is discourse analysis, more precisely, discourse analysis of the Geneva School under the direction of prof. Eddy Roulet. We used the same theoretical framework to characterize the mathematical discourse in French (see Toma 2009, Toma 2017). This general issue brings us to at least two particular goals: on the one hand, we must fram the specificity of the texture of the mathematical discourse (in the framework of the semantic and syntactic modules) and, on the other hand, we must grasp the flow of information in mathematical discourse (in the context of informational and topical organization)

Midline mandibular osteotomy in an asymmetric patient.

Abstract This case report shows the possibility of the application of a mandibular osteotomy to resolve mandibular asymmetry with independent and discordant movements of both bony segments. The authors report the case of a 25-year-old woman referred for mandibular asymmetry, with a transverse excess of the right hemi mandible and vertical defect of the left one. The patient underwent a bilateral sagittal split osteotomy, midline osteotomy, and genioplasty, which corrected the mandibular asymmetry with contraction of the entire right hemi mandible. A slight left vertical increase was also obtained through the surgically created lateral open bite. In the follow-up assessment, the patient's face appeared symmetrical with normalization of the bizygomatic-bigonial relationships, and the facial shape corresponded to ideal anthropometric features. This technique resulted in resolution of mandibular asymmetry. In addition, mandibular osteotomy permits the esthetic management of the shape of the entire mandibular body in relation to the other third of the face

Localização inicial da ponta de cateter central de inserção periférica (PICC) em recém-nascidos

This is a cross-sectional study aiming to identify the initial tip position of peripherally inserted central catheters (PICC) and to verify the prevalence of success in inserting such catheters in neonates. The study was carried out in the neonatal care unit of Hospital das Clínicas, Universidade de São Paulo. Data were collected prospectively from March to September 2006. 37 neonates underwent PICC insertion were included in the study. The rate of success for this procedure was 72.3% (27 neonates). Of them, four (14.8%) had the catheter tips placed in the axilary or inominate veins. Three others (11.1%) had them placed in a jugular vein. When these catheters were removed, 13 (48.2%) catheter tip were placed in the right atrium, and they were relocated to the superior vena cava.Estudio transversal con recolección prospectiva de datos. La finalidad fue identificar la posición inicial de la punta del catéter central de inserción periférica (PICC) y verificar la prevalencia de éxitos durante su introducción en neonatos. Los datos fueron recolectados en un servicio de neonatología anexo a la maternidad del Hospital de las Clínicas de la Facultad de Medicina de la Universidad de São Paulo, entre marzo y setiembre del 2006. De los 37 neonatos sometidos a introducción del catéter PICC, la tasa de éxito fue de 72.3% (27 neonatos), de ellos, cuatro (14.8%) estaban con las puntas de los catéteres alojadas en las venas axilar o no determinada, tres (11.1%) localizadas en la vena yugular. Siendo estos últimos retirados por desviación en su trayecto. El 48.2% (13) se encontraba con las puntas en el atrio derecho, siendo estos catéteres nuevamente posicionados en la vena cava superior.Estudo transversal com coleta prospectiva de dados, que objetivouidentificar o posicionamento inicial da ponta do cateter central de inserção periférica (PICC) e verificar a prevalência de sucesso de sua inserção em neonatos.

West Nile virus transmission. results from the integrated surveillance system in Italy, 2008 to 2015

IIn Italy a national Plan for the surveillance of imported and autochthonous human vector-borne diseases (chikungunya, dengue, Zika virus disease and West Nile virus (WNV) disease) that integrates human and veterinary (animals and vectors) surveillance, is issued and revised annually according with the observed epidemiological changes. Here we describe results of the WNV integrated veterinary and human surveillance systems in Italy from 2008 to 2015. A real time data exchange protocol is in place between the surveillance systems to rapidly identify occurrence of human and animal cases and to define and update the map of affected areas i.e. provinces during the vector activity period from June to October. WNV continues to cause severe illnesses in Italy during every transmission season, albeit cases are sporadic and the epidemiology varies by virus lineage and geographic area. The integration of surveillance activities and a multidisciplinary approach made it possible and have been fundamental in supporting implementation of and/or strengthening preventive measures aimed at reducing the risk of transmission of WNV trough blood, tissues and organ donation and to implementing further measures for vector control

Terminologia e interculturalità. Problematiche e prospettive

La terminologia contribuisce al consolidamento di patrimoni linguistici e culturali mentre la sua diffusione intra- e interlinguistica favorisce la costruzione di dialoghi interdisciplinari, evolvendo in parallelo a nuovi bisogni e contesti. Queste dinamiche si innestano nelle problematiche della comunicazione interculturale, tanto nelle pratiche dell’espressione quanto in quelle della traduzione interlinguistica. In questo volume, studiose e studiosi, specialiste e specialisti di terminologia presentano le loro riflessioni su queste tematiche, indagando la dimensione culturale e interculturale della ricerca terminologica e delle sue pratiche, interrogando tutti i fenomeni relativi all’incontro fra culture in atto nella realizzazione discorsiva di ambito specialistico. Tali riflessioni considerano ogni dimensione della testualità, fino agli spazi digitali, che offrono strumenti di analisi oltre i limiti della materialità, offrendo così un panorama ampio nel dibattito in corso, un terreno fertile per la verifica teorica alle questioni di ricerca in ambito terminologico

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
