Les épilepsies génétiques généralisées (ÉGGs) sont un groupe de syndromes épileptiques hétérogènes qui se manifestent habituellement durant les périodes de l’enfance et de l’adolescence. Les ÉGGs représentent 30% de toutes les épilepsies. Il n’existe présentement aucun remède à l’épilepsie génétique généralisée. Au sein de ce groupe d’épilepsies, les sujets sont le plus souvent dépourvus de lésions cérébrales, ce qui signifie que les facteurs génétiques jouent un rôle important dans l’étiologie de la maladie. Au cours des dernières années, plusieurs gènes impliqués dans des formes familiales d’ÉGG ont été identifiés. La majorité d'entre elles codent pour des canaux ioniques incluant le récepteur-ligand GABAA (RGABAA). De ce groupe, des mutations ont été identifiées dans quatre sous-unités du récepteur GABAA. Dans un premier temps, l’objectif général de cette thèse vise l’évaluation de la composante génétique de notre cohorte d’ÉGG expliquée par les gènes codant pour les sous-unités du récepteur GABAA. Puis, dans un second souffle, le rôle des variants identifiés est défini et analysé afin de mieux cerner leurs impacts dans la pathogénèse de ce phénotype. La première partie du projet consiste en une analyse exhaustive des mutations existantes dans la partie codante des 19 gènes GABRA pour des patients atteints d’ÉGG. En criblant des familles québécoises avec ÉGG, nous avons identifié 22 variants rares incluant 19 faux-sens et 3 non-sens dans 14 sous-unités du RGABAA. En séquençant ces gènes dans une grande cohorte de cas et de contrôles, nous avons établi le profil des variations rares pour ceux-ci. Ces données suggèrent qu’une proportion significative (8%) des patients atteints d’ÉGG ont des variants rares sur les gènes du RGABAA. La deuxième partie porte directement sur certains gènes identifiés lors de la première partie. De ce groupe, cinq nouvelles mutations ont été découvertes dans des gènes déjà associés à l’épilepsie (GABRA1 et GABRG2). Nous avons constaté l’impact de ces mutations dans les mécanismes génétiques de l’épilepsie, en mesurant les effets des variants sur la structure et la fonction du récepteur GABAA. La troisième partie se concentre sur notre hypothèse, voulant que les RGABAA mutants altèrent l’effet du GABA durant le développement du système nerveux central (SNC). L’objectif principal vise à déterminer la contribution relative de chacune des sous-unités mutées dans le développement du SNC. Ainsi, nous avons démontré qu’une telle perte de fonction a un impact significatif sur le développement des synapses GABAergiques et glutamatergiques ainsi que sur la plasticité des circuits corticaux. Nos résultats nous ont permis de préciser comment les mutations dans les gènes GABRA peuvent mener à l’ÉGG. Éventuellement, la caractérisation moléculaire de ces mutations contribuera à l’élaboration de nouveaux outils diagnostiques et facilitera la mise au point de traitements mieux ciblés pour les gens atteints de cette condition neurologique chronique.

Introduction : The acute care surgery (ACS) units are dedicated to the prompt management of surgical emergencies. It is a systemic way of organizing on-call services to diminish conflict between urgent care and elective obligations. The aim of this study was to define the characteristics of an ACS unit and to find common criteria in units with reported good functioning. Methods : As of July 1st 2014, 22 Canadian hospitals reported having an ACS unit. A survey with questions about the organization of the ACS units, the population it serves, the number of emergencies and trauma cases treated per year, and the satisfaction about the implementation of this ACS unit was sent to those hospitals. Results : The survey’s response rate was 73%. The majority of hospitals were tertiary or quaternary centers, served a population of more than 200 000 and had their ACS unit for more than three years. The median number of surgeons participating in an ACS unit was 8.5 and the majority were doing seven day rotations. The median number of operating room days was 2.5 per week. Most ACS units (85%) had an estimated annual volume of more than 2500 emergency consultations (including both trauma and non-trauma) and 80% operated over 1000 cases per year. Nearly all the respondents (94%) were satisfied with the implementation of the ACS unit in their hospital. Conclusion : Most surgeons felt that the implementation of an ACS unit resulted in positive outcomes. However, there should be a sizeable catchment population and number of surgical emergencies to justify the resulting financial and human resources.

Learning contents adaptation has been a subject of interest in the research area of the adaptive hypermedia systems. Defining which variables and which standards can be considered to model adaptive content delivery processes is one of the main challenges in pedagogical design over e-learning environments. In this paper some specifications, architectures and technologies that can be used in contents adaptation processes considering characteristics of the context are described and a proposal to integrate some of these characteristics in the design of units of learning using adaptation conditions in a structure of IMS-Learning Design (IMS-LD) is presented. The key contribution of this work is the generation of instructional designs considering the context, which can be used in Learning Management Systems (LMSs) and diverse mobile devices

Transitional provisions are defined as the set of regulations that rule juridical relationships on the occasion of a legislative change. Out of this context of law succession, their indiscriminate application can lead to serious inconsistencies. The analysis of a Spanish private law example is offered to illustrate this fact. It concerns the administrative authorization for the demolition of rented buildings in the cities. A regulation repealed more than fifteen years ago and however widespread utilised on ancient constructions that, after recent urban development, have acquired great economic value; something that in the end explains the current importance of such provisions. What is happening in Spain: denaturalization of the original  figure due to a mixture of formalist interpretations and speculative market interests, is presented here to call the attention on the necessary limitation of transitional provisions’ effects.

Introduction: During the past years, alveolar recruitment maneuvers (RM) have produced growing interest due to their beneficial potential in pulmonary protection, and have been introduced in clinical practice. Objective: To describe and analyze the knowledge of MR and its application at seven intensive care units in the city of Cali, Colombia. Methods and materials: Descriptive Cross-Sectional Study with an intentional sample of 64 professionals working in seven intensive care units and who apply MR. The self-completed survey was made up of thirteen questions, and the application period was two months. Results: Out of 64 professionals surveyed, 77.8% of them follow a protocol guide; 54.7% employes during RM the ideal Positive end-expiratory pressure (PEEP), which maintains a saturation > 90% and a PaO2 > 60 mmHg; 42.1% tolerates airway pressures between 35 and 50 cmH2O; 48.4% perform RM with a progressive increase of the PEEP and a low tidal volume. Conclusions: Regarding the knowledge related to RM, heterogeneity was found in the answers. There is currently no consensus about which is the most effective and secure way to implement an MR. This study can be the starting point to create awareness towards the revision of knowledge, capacities and abilities that are required to perform RM.
