Construcción de un diccionario didáctico digital para la mejora del aprendizaje del latín y estudio preliminar de su extensión a otras lenguas

Los objetivos de este proyecto son la creación de una versión digital, disponible en línea y en abierto, de un diccionario basado en un modelo inédito lexicográfico y cognitivo y el estudio preliminar de su generalización a otras lenguas. La eficacia didáctica del modelo de diccionario ha sido probada en este curso académico experimentalmente para la enseñanza presencial del latín utilizando una versión en papel. La idea es construir una versión digital para que el alumno pueda utilizarlo tanto para el trabajo en el aula como para el trabajo personal y estudiar si es viable su aplicación general al estudio de otras lenguas, especialmente de las lenguas modernas. El diccionario en formato digital proporcionaría, frente al papel, tres ventajas significativas: (1) aumentar su accesibilidad lo que facilitaría su uso en cualquier momento y lugar, (2) ayudar al alumno con dificultades a nivelarse puesto que podría usarlo para repetir los ejercicios de aprendizaje tantas veces como lo necesite, y, (3), servir de base para llevar a cabo acciones educativas basadas en la autoformación en línea que faciliten y fomenten el aprendizaje del latín en particular y de otras lenguas si el resultado del estudio preliminar es positivo respecto a su generalización

Women in Science: A Student Workshop at a University in Mexico

Women have participated in science since the earliest of times. However, their valuable contributions are not as widely acknowledged throughout our history and women still face several barriers throughout their professional career. We developed and hosted a half-day Women in Science seminar organized by students, for students. The main goal was to promote ways to involve more women in research activities and to strengthen the scientific community within our medical school. The workshop consisted of three main sections, where we shared relevant statistics, resources, and strategies among a community of students interested in science. At the end of the workshop, participants shared their insights proving the necessity and utility of such events to strengthen the development of science as an inclusive field

The occupation of Benzu Cave (Ceuta) by Neolithic and Bronze Age Societies

Abstract This study presents the results of the archaeological investigation in Benzú Cave, located on the North African shore of the Strait of Gibraltar. The archaeological deposits, approximately 1 m deep, belong to two occupational levels dated to theNeolithic and the Bronze Age. Awide range of artifacts was found, and this led to an interdisciplinary study that led us to reach new conclusions concerning the material life, subsistence economy, and environment of the Neolithic and Bronze Age societies in northern Africa and the southern Iberian Peninsula.Résumé Cette étude présente les résultats des recherches archéologiques menées dans la grotte de Benzú, située sur la rive nord-africaine du détroit de Gibraltar. Les gisements archéologiques, d'environ un mètre de profondeur, appartiennent à deux niveaux d'occupation datant du néolithique et de l'âge du bronze. Une large gamme d'artefacts ont été trouvés, ce qui a conduit à une étude interdisciplinaire qui nous a amenés à tirer de nouvelles conclusions concernant la vie matérielle, l'économie de subsistance et l'environnement des sociétés du Néolithique et de l'Age du Bronze en Afrique du Nord et au sud de la Péninsule Ibérique

Comprehensive description of clinical characteristics of a large systemic Lupus Erythematosus Cohort from the Spanish Rheumatology Society Lupus Registry (RELESSER) with emphasis on complete versus incomplete lupus differences

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement and pronounced racial and ethnic heterogeneity. The aims of the present work were (1) to describe the cumulative clinical characteristics of those patients included in the Spanish Rheumatology Society SLE Registry (RELESSER), focusing on the differences between patients who fulfilled the 1997 ACR-SLE criteria versus those with less than 4 criteria (hereafter designated as incomplete SLE (iSLE)) and (2) to compare SLE patient characteristics with those documented in other multicentric SLE registries. RELESSER is a multicenter hospital-based registry, with a collection of data from a large, representative sample of adult patients with SLE (1997 ACR criteria) seen at Spanish rheumatology departments. The registry includes demographic data, comprehensive descriptions of clinical manifestations, as well as information about disease activity and severity, cumulative damage, comorbidities, treatments and mortality, using variables with highly standardized definitions. A total of 4.024 SLE patients (91% with ≥4 ACR criteria) were included. Ninety percent were women with a mean age at diagnosis of 35.4 years and a median duration of disease of 11.0 years. As expected, most SLE manifestations were more frequent in SLE patients than in iSLE ones and every one of the ACR criteria was also associated with SLE condition; this was particularly true of malar rash, oral ulcers and renal disorder. The analysis-adjusted by gender, age at diagnosis, and disease duration-revealed that higher disease activity, damage and SLE severity index are associated with SLE [OR: 1.14; 95% CI: 1.08-1.20 (P < 0.001); 1.29; 95% CI: 1.15-1.44 (P < 0.001); and 2.10; 95% CI: 1.83-2.42 (P < 0.001), respectively]. These results support the hypothesis that iSLE behaves as a relative stable and mild disease. SLE patients from the RELESSER register do not appear to differ substantially from other Caucasian populations and although activity [median SELENA-SLEDA: 2 (IQ: 0-4)], damage [median SLICC/ACR/DI: 1 (IQ: 0-2)], and severity [median KATZ index: 2 (IQ: 1-3)] scores were low, 1 of every 4 deaths was due to SLE activity. RELESSER represents the largest European SLE registry established to date, providing comprehensive, reliable and updated information on SLE in the southern European population

Combination of Tocilizumab and Steroids to Improve Mortality in Patients with Severe COVID-19 Infection : A Spanish, Multicenter, Cohort Study

We aimed to determine the impact of tocilizumab use on severe COVID-19 (coronavirus disease 19) pneumonia mortality. We performed a multicentre retrospective cohort study in 18 tertiary hospitals in Spain from March to April 2020. Consecutive patients admitted with severe COVID-19 treated with tocilizumab were compared to patients not treated with tocilizumab, adjusting by inverse probability of the treatment weights (IPTW). Tocilizumab's effect in patients receiving steroids during the 48 h following inclusion was analysed. During the study period, 506 patients with severe COVID-19 fulfilled the inclusion criteria. Among them, 268 were treated with tocilizumab and 238 patients were not. Median time to tocilizumab treatment from onset of symptoms was 11 days [interquartile range (IQR) 8-14]. Global mortality was 23.7%. Mortality was lower in patients treated with tocilizumab than in controls: 16.8% versus 31.5%, hazard ratio (HR) 0.514 [95% confidence interval (95% CI) 0.355-0.744], p < 0.001; weighted HR 0.741 (95% CI 0.619-0.887), p = 0.001. Tocilizumab treatment reduced mortality by 14.7% relative to no tocilizumab treatment [relative risk reduction (RRR) 46.7%]. We calculated a number necessary to treat of 7. Among patients treated with steroids, mortality was lower in those treated with tocilizumab than in those treated with steroids alone [10.9% versus 40.2%, HR 0.511 (95% CI 0.352-0.741), p = 0.036; weighted HR 0.6 (95% CI 0.449-0.804), p < 0.001] (interaction p = 0.094). These results show that survival of patients with severe COVID-19 is higher in those treated with tocilizumab than in those not treated and that tocilizumab's effect adds to that of steroids administered to non-intubated patients with COVID-19 during the first 48 h of presenting with respiratory failure despite oxygen therapy. Randomised controlled studies are needed to confirm these results.

Post-Hospital Syndrome and Hyponatremia

Introduction: Post-hospital syndrome (PHS) is defined as a period of vulnerability during the first 30 days after a patient is discharged from hospital, in which multiple factors come into play. Hyponatremia is the most frequent hydroelectrolytic disorder in hospitalized patients and may be related to the appearance of PHS. Objective: The objective is to estimate the prevalence of PHS that is assessed as the rate of readmissions in the first 30 days after discharge, in patients with hyponatremia. Material and Methods: It is a descriptive observational study of patients with hyponatremia who were discharged from 1 September 2010 to 2 February 2020 at the Internal Medicine Service of the Hospital University of San Juan (Alicante, Spain). Results: Of the 25 included patients, 5 (20%) were readmitted within a month of discharge, after a mean of 11.4 days (standard deviation [SD] 5.1). The overall mortality of the study was 20% (n = 5), with one case of death in the first 30 days post-hospitalization (4%). In 12 patients (48%) the origin of the hyponatremia was undetermined. The most frequently recorded etiology for the condition was pharmacological (n = 7, 28%), and there was pronounced variability in its clinical and laboratory study. The most widely used corrective measure was drug withdrawal, in 16 patients (64%). Water intake restriction was the most common treatment after discharge (5 patients, 20%), followed by urea (2 patients, 8%), while tolvaptan was not used. Conclusion: Hyponatremia may be the cause of PHS, which could increase the rate of early readmission. Hyponatremia is an underdiagnosed and undertreated entity, so it is necessary to apply an appropriate system to optimize its management and, in future studies, to assess its impact on PHS

Ecotoxicity of insecticides of frequent use in tomatoes on Trichogramma achaeae (Hymenoptera: Trichogrammatidae)

Since Tuta absoluta(Meyrick) (Lepidoptera: Gelechiidae) was detected in 2006 as a new pest in tomato crops in Spain, several natural enemies have been reported tocontrol this pest. In biological control programs, the native parasitoid Trichogramma achaeae Nagaraja&Nagarkatti (Hymenoptera: Trichogrammatidae) is used against T.absoluta. However, the most common control practice is based on use of pesticides,and in the frame of Integrated Pest Management (IPM) programs, the knowledge on the activity of insecticides towards beneficial insects is needed for its joint use. In thiswork, we evaluated lethal and sublethal effects of insecticides commonly applied on tomato crops on adults of T. achaeae. Pesticides were sprayed on tomato plants or T. Absoluta eggs till run off at their maximum field recommended concentration. Mortality was scored after 24, 48 and 72 hours, as well as beneficial capacity and percentage of emergence
