Animated PowerPoint Videos: An Underutilized Anatomy Educational Tool?

The subject of anatomy is an integral component of medical and dental education which are constantly evolving. Hence, educators continuously attempt to take advantage of technological advancements to create resources that will improve students’ higher cognitive skills. This article describes the creation of an e-learning resource in the form of an animated PowerPoint video that was designed based on evidence-based principles and educational theories to introduce the concept of tooth anatomy. Additionally, it outlines how this resource can be potentially integrated into a broader educational system as well as encourage anatomy and medical educators to use less complex technological equipment to create accessible educational resources

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Des dieux et des plantes. Monde végétal et religion en Grèce ancienne

L’ouvrage présent rend hommage à l’emblématique ouvrage Prairies et Jardins… d’André Motte (1973) en proposant une moisson toute fraîche de questionnements et de points de vue sur les verts paysages du monde polythéiste des anciens Grecs, ainsi que les espèces et les plantes isolées qui ont poussé sur son sol. Les auteurs du volume, attentifs aux renouvellements à l’œuvre dans l’étude de la religion grecque ancienne, grâce aux recherches de plusieurs décennies, montrent qu’à la pluralité des dieux et des enceintes sacrées correspondent un regard diversifié et une façon dynamique d’envisager l’élément végétal constitutif de l’expérience religieuse. En refusant les approches naturalistes réductrices et les aperçus conventionnels, les études ici rassemblées tiennent compte, notamment, du dialogue perpétuel entre quête théorique ou poétique, réalités rituelles ou politiques, qui régit le polythéisme grec ancien. Elles abordent aussi la dimension locale des récits et des cultes. Sont ainsi mis en perspective des plantes réelles et imaginaires, à travers le vocabulaire concret du végétal, les récits et les croyances indigènes, la topographie des sanctuaires, les calendriers des fêtes, les épiclèses et les attributs divins, les gestes rituels et la pharmacopée. Loin d’épuiser le thème en question, cette promenade interdisciplinaire a l’ambition d’en révéler la complexité en ouvrant des pistes captivantes
