Emergent and delayed hybrid external fixation management of tibial pilon fractures: A multicentric retrospective analysis of 80 patients

Objective: To report our experience with the hybrid external fixator in emergency.Methods: We assessed 80 cases of pilon fracture treated with the external fixator during the period of January 2009 and December 2016:55 men (69%) and 30 women (33%) with a mean age of 40 years (range between 16 and 70). About 45 occurred as isolated trauma, 35 instead were politrauma. Each patient underwent standard radiographic examination and a CT examination. There were 28 open fractures (35%), (Gustilo type 1, 2 and 3) while closed fractures showed soft tissue involvement of various grade (2-3 Tscherne classification). In all cases, the external fixation, sometimes associated with other reduction and synthesis techniques, was used. The timing of surgery was dictated by the condition of the soft tissues. For clinical evaluation, the Mazur score with mean follow-ups at 12 months was utilized.Results: The final range of ankle motion was 15 dorsal and 10 plantar flexion. In about 80 cases there was an average Mazur score of83. The mean score was 90; in open fractures 85 to 72. Radiographic healing of fractures in 60 patients occurred in 120 days (mean 105 days), at the time when the external fixator was removed.Conclusion: Pilon fractures are complex and often present complications; the definitive treatment, in emergency or delayed, with hybrid external fixator permits a stable synthesis with minimal soft tissue damage. Weight bearing maybe allowed early and functional recovery is generally good

Gamma-Ray Burst observations by the high-energy charged particle detector on board the CSES-01 satellite between 2019 and 2021

In this paper we report the detection of five strong Gamma-Ray Bursts (GRBs) by the High-Energy Particle Detector (HEPD-01) mounted on board the China Seismo-Electromagnetic Satellite (CSES-01), operational since 2018 on a Sun-synchronous polar orbit at a $\sim$ 507 km altitude and 97$^\circ$ inclination. HEPD-01 was designed to detect high-energy electrons in the energy range 3 - 100 MeV, protons in the range 30 - 300 MeV, and light nuclei in the range 30 - 300 MeV/n. Nonetheless, Monte Carlo simulations have shown HEPD-01 is sensitive to gamma-ray photons in the energy range 300 keV - 50 MeV, even if with a moderate effective area above $\sim$ 5 MeV. A dedicated time correlation analysis between GRBs reported in literature and signals from a set of HEPD-01 trigger configuration masks has confirmed the anticipated detector sensitivity to high-energy photons. A comparison between the simultaneous time profiles of HEPD-01 electron fluxes and photons from GRB190114C, GRB190305A, GRB190928A, GRB200826B and GRB211211A has shown a remarkable similarity, in spite of the different energy ranges. The high-energy response, with peak sensitivity at about 2 MeV, and moderate effective area of the detector in the actual flight configuration explain why these five GRBs, characterised by a fluence above $\sim$ 3 $\times$ 10$^{-5}$ erg cm$^{-2}$ in the energy interval 300 keV - 50 MeV, have been detected.Comment: Accepted for publication in The Astrophysical Journal (ApJ

Russi, V. 2019. “La sinonimia tra proposizioni coordinate: expolitio e interpretatio nella Commedia di Dante”. Open Journal of Humanities 1: 423-449.

This contribution focuses on coordinated synonymous clauses in Dante’s Commedia. After having clarified the rhetorical value of this particolar syntactic construction (with the help of both ancient and modern interpretations), the analysis focuses on its individual occurrences, illustrating the different ways in which the synonymic structure affects the text. All these different forms are shown to be one of the tools with which the author carried out his extraordinary research on vernacular language

VALUATION AND RESCUE OF UNRECOGNIZED OR DECLARED HERITAGE. QUINTA PAREDES NEIGHBORHOOD, BOGOTÁ.

El trabajo de grado evalúa y propone un ejemplo para modernizar la arquitectura de una de las manzanas del barrio Quinta Paredes. Esta propuesta aborda la necesidad de preservar la arquitectura existente, al mismo tiempo que se busca aumentar la disponibilidad de viviendas, manteniendo la alta calidad que caracteriza a estas edificaciones. La estrategia consiste en realizar modificaciones en el interior de las casas a través de nuevas distribuciones espaciales y la actualización de las redes. Asimismo, se propone intervenir los antejardines, integrándolos para crear un espacio público-privado que fomente la vida en comunidad y que sea gestionado de manera especial para satisfacer las necesidades de los residentes. En relación con las fachadas, se persigue la conservación estética del conjunto mediante ajustes en los materiales, reparaciones o modificaciones que resalten el lenguaje arquitectónico presente en las edificaciones.The thesis appreciates and illustrates an approach to modernize the architecture within one of the blocks in the Quinta Paredes neighborhood. This initiative addresses the imperative to both conserve the existing architectural character and augment the housing capacity, all while preserving the inherent quality of these structures. This is achieved through alterations to the interior layouts, introducing new spatial arrangements, and upgrading networks. Additionally, the front gardens are to be reimagined, integrated to establish a public-private space conducive to community life. The houses requiring special management are adapted to fulfill the unique needs of the block's residents, transforming into facilities that enhance the overall quality of life in the neighborhood. Concerning the facades, the emphasis lies in aesthetically conserving the system through adjustments in materials, repairs, or modifications aimed at accentuating the inherent architectural languageArquitecto (a)Pregrad

The experience of leaving and forcibly returning to the home of young university students

El presente estudio tuvo como objetivo describir la experiencia de salir del hogar de jóvenes universitarios y su regreso forzoso a causa de la pandemia del Covid 19. Se implementó un método de tipo cualitativo con estudio de caso múltiple, en cuatro jóvenes con edades entre los 22 y 25 años provenientes de la ciudad de Villavicencio que residen en Bogotá debido a sus estudios universitarios. La elección de los participantes se realizó de manera no probabilística y por cuotas, ya que se buscó intencionalmente seleccionar dos personas de ambos sexos. Las entrevistas evidenciaron que, tanto la salida del hogar de los jóvenes, como su regreso forzoso, constituyen transiciones en las cuales los jóvenes atraviesan un momento inicial de desequilibrio que conlleva a un ajuste conductual, cognitivo y emocional y a un crecimiento personal en el proceso de desarrollo de los universitarios. Adicionalmente, a pesar de los momentos difíciles y los desacuerdos que en un principio los jóvenes pudieron mantener con sus padres al regresar al hogar, luego de cierto lapso de tiempo, existe una adaptación en la reciente convivencia en condiciones de confinamiento obligatorio.Estudiantes universitariosThe present study aimed to describe the experience of young university students of leaving home and their forced return due to the Covid 19 pandemic. A qualitative method with a multiple case study was implemented in four young people aged between 22 and 25 years from the city of Villavicencio who reside in Bogota due to their university studies. The choice of participants was carried out in a non-probabilistic quota sampling, since it was intentionally sought to select two people of both sexes. The interviews showed that leaving home and the forced return of young people are transitions which go through an initial moment of imbalance that lead to a behavioral, cognitive and emotional adjustment and personal growth in the development process of the university students. Additionally, despite the difficult moments and the disagreements that the young people maintained with their parents at first, it is possible to observe that, after a certain period of time, there is an adaptation in the recent coexistence at home.Psicólogo (a)Pregrad

Continuous Femoral Catheter for Postoperative Analgesia After Total Knee Arthroplasty

Introduction: Postoperative pain management in the total knee replacement (TKR) represent a fundamental step for a positive outcome, allowing rapid mobilization, already on the first day. Further, continuous peripheral nerve block techniques have been reported to allow effective and safe control of acute postoperative pain, ensuring the implementation and completion of an accurate and intensive joint rehabilitation program. Aim: The aim of this study was to assess early mobility and compliance of patients that underwent TKR surgery using the femoral block. Methods: For the study, all patients that underwent TKR from 2015 to 2018 with ASA score between II-III was evaluated. Patients underwent vital parameters monitoring and were treated initially with midazolam (0.05mg / kg) e.v. combined sciatic block + femoral perineural catheter positioning using a peripheral nerve stimulation-assisted technique. Results: Intraoperatively, satisfactory analgesia was guaranteed in all patients, associated with a complete muscle relaxation of the affected limb. High patient compliance, associated with good control of acute postoperative pain was obtained in the first 24 hours after surgery (VAS 0- 1). The ROM outcomes were good in all rehabilitation stages, managing to reach 90 degrees bending on the seventh day with an average KSS score of 88-90. Patient satisfaction and impact on quality of life were assessed with the SF-36 showing average scores of 78. Conclusion: Continuous femoral nerve blocking ensures good postoperative analgesia in TKR allowing an early joint mobilization, a rapid functional recovery of the knee and increasing patient compliance during the post-operative rehabilitation program
