Género y participación… Entre los usos del espacio y la palabra

El presente trabajo sistematiza la experiencia del año 2019 en el Centro Juvenil Lamistá en el marco del Espacio de Formación Integral «Cuerpo y Educación en Malvín Norte». El trabajo tiene como propósito el análisis de los registros de observación participante de la primera parte del semestre en el taller llevado a cabo por el equipo de educadores del centro denominado «Charlas y charlitas», así como también de otros registros de los momentos previos y posteriores a este, de las reuniones con el equipo y de los talleres con el grupo de adolescentes. Además, este trabajo establece continuidades con el trabajo de sistematización y análisis realizado en el Centro Juvenil en el año 2018, presente en el dossier. El análisis se estructura a partir del género en tanto categoría analitica, entendida como aquellas significaciones que se construyen ritualizada y performativamente sobre los cuerpos sexuados. En el trabajo analizamos y reflexionamos sobre la participación en el centro juvenil en función del género, puesto que tanto en los usos del espacio como en los de la palabra, existen diferentes formas de participar que se construyen de acuerdo a cierta ritualización de las prácticas y representaciones sociales vinculadas a lo femenino y a lo masculino. A partir de esto, nos preguntamos ¿Cuál es la relación entre la construcción de los géneros, la ocupación de los espacios y el uso de la palabra enel relacionamiento entre adolescentes del centro? ¿Cómo se configuran en torno a relaciones de poder? ¿De qué manera se implican con el cuerpo estas relaciones de poder

Maths complements for Computational Mechanics a ATENEA Labs

Els estudiants que ingressen als màsters en anglès de la UPC provinents d’altres països sovint tenen carències en coneixements bàsics de matemàtiques que s’imparteixen al primer cicle (Bachelor). El nostre projecte consisteix en crear una eina interactiva i s'ha concebut com una font de consulta per facilitar a aquests estudiants recordar o apendre aquests conceptes bàsics. S'han creat mòduls temàtics on es defineixen conceptes de matemàtiques útils pels estudiants de diferents màsters i s'han creat exercicis interactius d'autoaprenentatge.Peer Reviewe

Mortality risk estimation in acute calculous cholecystitis : beyond the Tokyo Guidelines

Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments. The recommended treatment is the early laparoscopic cholecystectomy; however, the Tokyo Guidelines (TG) advocate for different initial treatments in some subgroups of patients without a strong evidence that all patients will benefit from them. There is no clear consensus in the literature about who is the unfit patient for surgical treatment. The primary aim of the study is to identify the risk factors for mortality in ACC and compare them with Tokyo Guidelines (TG) classification. Retrospective unicentric cohort study of patients emergently admitted with and ACC during 1 January 2011 to 31 December 2016. The study comprised 963 patients. Primary outcome was the mortality after the diagnosis. A propensity score method was used to avoid confounding factors comparing surgical treatment and non-surgical treatment. The overall mortality was 3.6%. Mortality was associated with older age (68 IQR 27 vs. 83 IQR 5.5; P = 0.001) and higher Charlson Comorbidity Index (3.5 5.3 vs. 02; P = 0.001). A logistic regression model isolated four mortality risk factors (ACME): chronic obstructive pulmonary disease (OR 4.66 95% CI 1.7-12.8 P = 0.001), dementia (OR 4.12; 95% CI 1.34-12.7, P = 0.001), age 80 years (OR 1.12: 95% CI 1.02-1.21, P = 0.001) and the need of preoperative vasoactive amines (OR 9.9: 95% CI 3.5-28.3, P = 0.001) which predicted the mortality in a 92% of the patients. The receiver operating characteristic curve yielded an area of 88% significantly higher that 68% (P = 0.003) from the TG classification. When comparing subgroups selected using propensity score matching with the same morbidity and severity of ACC, mortality was higher in the non-surgical treatment group. (26.2% vs. 10.5%). Mortality was higher in ACC patients treated with non-surgical treatment. ACME identifies high-risk patients. The validation to ACME with a prospective multicenter study population could allow us to create a new alternative guideline to TG for treating ACC. Retrospectively registered and recorded in Clinical Trials

Micromón València (Universitat de València)

En Julio de 2017 se creó la red SWI@Spain, auspiciada por el grupo de Docencia y Difusión de la Microbiología (DDM) de la Sociedad Española de Microbiología (SEM), para desarrollar la iniciativa internacional Small World Initiative (SWI) en la península ibérica. En la Universitat de València (UV) se constituyó entonces el grupo de Innovación Docente en Microbiología (IDM) para implementar el proyecto a nivel local. Avalados por el Servei de Formació Permanent i Innovació Educativa (SFPIE) de la UV, el grupo ha llevado a cabo diferentes iniciativas relacionadas con el objetivo fundamental del proyecto: divulgar la problemática actual relacionada con el uso inadecuado de antibióticos, el incremento de bacterias resistentes a éstos y la necesidad de encontrar nuevas moléculas con actividad antibacteriana para combatir las infecciones que provocan

Global Retinoblastoma Presentation and Analysis by National Income Level.

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68]). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs
