Influence of manufacturing parameters on the mechanical properties of projection stereolithography–manufactured specimens
This study focuses on the impact of different fabrication parameters (build orientation, layer thickness and post-curing time) on the mechanical properties of parts fabricated through projection stereolithography technology. A Titan 2 HR printer (Kudo3D Inc.©) was used to print the specimens. Three different resins have been investigated. Specimens have been organised in 7 families for each material. Besides the different chemical compositions of the resins, the results globally show that the most influential factor on the mechanical properties (ultimate tensile strength, Young’s modulus, elongation at break) is the build orientation. Contrarily, the effect of the post-curing time has proved to be highly dependent on the chemical composition of polymers, playing a significant role only for resins that do not complete the polymerisation process during printing and therefore require a subsequent treatment time. Layer thickness in this application has shown a relevant influence on the mechanical characteristics of the studied resins.
Apport de l’échographie clinique dans la prise en charge des douleurs abdominales aiguës non traumatiques chez l’adulte dans les services d’urgence : une étude rétrospective monocentrique dans un centre hospitalier général
Objectif : Déterminer si la réalisation d’une échographie clinique en médecine d’urgence (ECMU) modifie la prise en charge des patients présentant une douleur abdominale aiguë d’origine non traumatique. Matériel et méthodes : Étude rétrospective, monocentrique, incluant les patients qui ont consulté aux urgences pour douleur abdominale aiguë d’origine non traumatique entre le 1 er juin 2019 et le 31 octobre 2019. Les données recueillies étaient le nombre d’examens complémentaires d’imagerie réalisés, le temps de prise en charge, le taux d’hospitalisation, le diagnostic et le taux de reconsultation à 30 jours. Le critère de jugement principal était le recours aux examens complémentaires d’imagerie spécialisée (parmi lesquels : échographie spécialisée, tomodensitométrie abdominopelvienne et abdomen sans préparation) chez les patients ayant bénéficié d’une échographie clinique (groupe « ECMU ») comparativement aux patients n’ayant pas bénéficié d’échographie (groupe « sans ECMU »). Résultats : Mille cinquante-trois patients ont été inclus. Parmi ces patients, 16 % ont bénéficié d’une échographie clinique par le médecin urgentiste. Il existait une réduction significative du recours à l’échographie spécialisée dans le groupe ECMU (4 % dans le groupe « avec ECMU » versus 9 % dans le groupe « sans ECMU », OR = 0,45, IC 95 % : [0,17–1,00], p = 0,04), sans différence significative entre les deux groupes concernant le temps de prise en charge, l’orientation, le taux de reconsultation à 30 jours et la concordance diagnostique. Conclusion : La réalisation d’une ECMU dans l’exploration des douleurs abdominales aiguës d’origine non traumatique entraînait une réduction significative du nombre d’échographies spécialisées, sans pour autant diminuer le temps de prise en charge ni la concordance entre le diagnostic posé aux urgences et celui en fin d’hospitalisation. Objective : To determine if point of care ultrasonography (POCUS) has an impact on the management of nontraumatic acute abdominal pain. Methods : This was a single-center retrospective study, including patients who were admitted in the emergency room of the hospital of Saint-Lô, France, for non-traumatic acute abdominal pain, between 01 June 2019 and 31 October 2019. The data collected were the number of subsequent imaging tests performed, the length of stay, the hospitalization rate, the diagnosis, and the reconsultation rate within 30 days. The primary outcome was the realization of an imaging test (among radiologist ultrasonography, abdominopelvic scanner, and plain abdominal X ray) in patients who underwent a point of care ultrasonography (POCUS group) as compared to those who did not (non-POCUS group). Results : One thousand fifty-three patients were included. Sixteen percent of those patients underwent POCUS. There were significantly fewer prescriptions for radiologist ultrasonography in the POCUS group (4% in the POCUS group versus 9% in the non-POCUS group, OR = 0.45, IC 95%: [0.17-1.00], P = 0.04). There was no significant difference between the two groups concerning the length of stay, hospitalization, reconsultation rates and diagnosis agreement. Conclusion : POCUS in the exploration of non-traumatic acute abdominal pain reduced the prescription of radiologist ultrasonography, without reducing the length of stay and the agreement between the emergency and the hospitalization diagnosis.
