Visual analysis of electroencephalography (EEG) background and reactivity during therapeutic hypothermia provides important outcome information, but is time-consuming and not always consistent between reviewers. Automated EEG analysis may help quantify the brain damage. Forty-six comatose patients in therapeutic hypothermia, after cardiac arrest, were included in the study. EEG background was quantified with burst-suppression ratio (BSR) and approximate entropy, both used to monitor anesthesia. Reactivity was detected through change in the power spectrum of signal before and after stimulation. Automatic results obtained almost perfect agreement (discontinuity) to substantial agreement (background reactivity) with a visual score from EEG-certified neurologists. Burst-suppression ratio was more suited to distinguish continuous EEG background from burst-suppression than approximate entropy in this specific population. Automatic EEG background and reactivity measures were significantly related to good and poor outcome. We conclude that quantitative EEG measurements can provide promising information regarding current state of the patient and clinical outcome, but further work is needed before routine application in a clinical setting.

Les dernières recommandations américaines concernant la prise en charge des dyslipidémies en prévention cardiovasculaire ont soulevé de nombreuses questions par leurs différences avec nos approches habituelles. Entre autres, elles ont éradiqué la nécessité de « cible » de LDL-C à atteindre en fonction du niveau de risque cardiovasculaire et ont proposé plutôt une stratégie basée sur l’intensité de la réduction relative du LDL-C. L’examen critique et la comparaison des recommandations font apparaitre, toutefois, plus de similitudes que de différences, tout en encourageant à repenser certains aspects de notre pratique et à raviver notre motivation pour le plus grand bien des patients.

The inverse dynamics of flexible multibody systems is formulated as a two-point boundary value problem for an index-3 differential-algebraic equation (DAE). This DAE represents the equation of motion with kinematic and trajectory constraints. For so-called nonminimum phase systems, the remaining dynamics of the inverse model is unstable. Therefore, boundary conditions are imposed not only at the initial time but also at the final time in order to obtain a bounded solution of the inverse model. The numerical solution strategy is based on a reformulation of the DAE in index-2 form and a multiple shooting algorithm, which is known for its robustness and its ability to solve unstable problems. The paper also describes the time integration and sensitivity analysis methods that are used in each shooting phase. The proposed approach does not require a reformulation of the problem in input-output normal form known from nonlinear control theory. It can deal with serial and parallel kinematic topology, minimum phase and nonminimum phase systems, and rigid and flexible mechanisms. [less ▲]

Tendon lesions are among the most frequent musculoskeletal pathologies. Vascular endothelial growth factor (VEGF) is known to regulate angiogenesis. VEGF-111, a biologically active and proteolysis-resistant splice variant of this family, was recently identified. This study aimed at evaluating whether VEGF-111 could have a therapeutic interest in tendon pathologies. Surgical section of one Achilles tendon of rats was performed before a local injection of either saline or VEGF-111. After 5, 15 and 30 days, the Achilles tendons of 10 rats of both groups were sampled and submitted to a biomechanical tensile test. The force necessary to induce tendon rupture was greater for tendons of the VEGF-111 group (p<0.05) while the section areas of the tendons were similar. The mechanical stress was similar at 5 and 15 days in the both groups but was improved for the VEGF-111 group at day 30 (p <0.001). No difference was observed in the mRNA expression of collagen III, tenomodulin and MMP-9. In conclusion, we observed that a local injection of VEGF-111 improves the early phases of the healing process of rat tendons after a surgical section. Further confirmatory experimentations are needed to consolidate our results. [less ▲]

Recent progress in computer science and stringent requirements of the design of “greener” buildings put forwards the research and applications of simulation-based optimization methods in the building sector. This paper provides an overview on this subject, aiming at clarifying recent advances and outlining potential challenges and obstacles in building design optimization. Key discussions are focused on handling discontinuous multi-modal building optimization problems, the performance and selection of optimization algorithms, multi-objective optimization, the application of surrogate models, optimization under uncertainty and the propagation of optimization techniques into real-world design challenges. This paper also gives bibliographic information on the issues of simulation programs, optimization tools, efficiency of optimization methods, and trends in optimization studies. The review indicates that future researches should be oriented towards improving the efficiency of search techniques and approximation methods (surrogate models) for large-scale building optimization problems; and reducing time and effort for such activities. Further effort is also required to quantify the robustness in optimal solutions so as to improve building performance stability. [less ▲]

Higher education institutions have been actively attempting to integrate sustainability in their curricula, research, operations, and outreach activities over the last decades. Despite the efforts undertaken, it is currently still challenging for their internal and external stakeholders to assess an institution’s sustainability-related activities and the extent of their implementation within the different activities of higher education. Since sustainability reporting in higher education is currently still in its early stages, and because a holistic view of sustainability integration in higher education on a management level is often lacking, this paper researches possible contributions of management control to sustainability reporting and the sustainability integration process in higher education. The paper adheres to a management control approach by applying Simons’ (1995) Levers of Control Framework to the field of sustainability in higher education, in search for a theoretical framework for reporting and integrating sustainability on a strategic level into higher education institutions. The research stresses the need for a holistic approach and for further in-depth study into certain aspects of the control framework, i.e., practical implementation of vision and mission statements, the concept of materiality, staff development, diagnostic indicator development, and the study of stakeholder engagement processes in higher education [less ▲]

La culture de sécurité en santé publique a 40 ans de retard Le rapport de l’IOM (Institute of Medicine), publié en 1999, met le doigt sur les risques auxquels les patients s’exposent en rentrant dans un secteur hospitalier. Ces nombres éloquents ne sont pas l’apanage d’un système de santé publique particulier, par ailleurs fortement décrié et propre aux Etats Unis d’Amérique. Les statistiques dans d’autres systèmes de santé sont identiques et l’OMS clame aujourd’hui que, lorsque vous êtes admis dans un hôpital, vous avez 10% de risque d’en sortir moins bien qu’à l’entrée (European Union Network for Patient Safety). Et pourtant, tous les acteurs du terrain se gargarisent avec le slogan «priorité à la sécurité». Malheureusement, il s’agit là souvent simplement d’un slogan qui ne se reflète pas dans nos pratiques journalières. Et c’est là que le secteur de la santé se différencie singulièrement des autres domaines d’activités industrielles dits à haut risque (aviation civile, centrales atomiques, industrie alimentaire), qui ont depuis longue date un «management du risque opérationnel» organisé, structuré et prospectif. Un des principes de base du management du risque est la mesure: dans les écoles managériales on apprend que l’on ne peut manager ce que l’on ne mesure pas. Mesurons-nous les risques en santé publique? Avons-nous des indicateurs fiables, reproductibles, transparents qui nous donnent une idée de la sécurité et de la qualité de nos pratiques? L’incidence des risques systémiques – et je préfère utiliser ce terme plutôt que celui d’«erreur médicale» – est certainement sous-estimée, car il n’y pas en santé publique une culture de sécurité qui prône la déclaration spontanée et transparente de tous les événements, qu’ils soient indésirables (sans effet délétère pour le patient) ou greffés d’effet mineur (incident) ou majeur (accident).
