BIMS: Biomedical Information Management System

This final year project presents the design principles and prototype implementation of BIMS (Biomedical Information Management System), a flexible software system which provides an infrastructure to manage all information required by biomedical research projects.The BIMS project was initiated with the motivation to solve several limitations in medical data acquisition of some research projects, in which Universitat Pompeu Fabra takes part. These limitations,based on the lack of control mechanisms to constraint information submitted by clinicians, impact on the data quality, decreasing it.BIMS can easily be adapted to manage information of a wide variety of clinical studies, not being limited to a given clinical specialty. The software can manage both, textual information, like clinical data (measurements, demographics, diagnostics, etc ...), as well as several kinds of medical images (magnetic resonance imaging, computed tomography, etc ...). Moreover, BIMS provides a web - based graphical user interface and is designed to be deployed in a distributed andmultiuser environment. It is built on top of open source software products and frameworks.Specifically, BIMS has been used to represent all clinical data being currently used within the CardioLab platform (an ongoing project managed by Universitat Pompeu Fabra), demonstratingthat it is a solid software system, which could fulfill requirements of a real production environment.

Laparoscopic and open colorectal surgery in everyday practice : retrospective study

Résumé Introduction: La plupart des études disponibles sur la chirurgie colorectale par laparoscopie concernent des patients hautement sélectionnés. Le but de cette étude est d'analyser les résultats à court et à long terme de l'ensemble des patients traités dans un service de chirurgie générale. Méthodes: Il s'agit d'une analyse rétrospective d'un registre prospectif interne au service, dans lequel tous les patients consécutifs opérés pour la première fois du colon et du rectum entre mars 1993 et décembre 1997 ont été enregistrés. Les informations concernant le suivi ont été collectées par questionnaire. Résultats: Un total de 187 patients ont été opérés par laparoscopie et 215 patients par chirurgie ouverte durant la période d'étude. Les informations concernant le suivi ont pu être collectées dans 95% des cas avec une évolution de 1-107 mois (médiane 59 mois), respectivement de 1-104 mois (médiane 53 mois). Une conversion fut nécessaire dans 28 cas (15%) mais ceux-ci restent inclus dans le groupe laparoscopie pour l'analyse par intention de traitement. Dans le groupe laparoscopie, les opérations ont duré plus longtemps (205 vs 150 min, p<0.001) mais l'hospitalisation a été plus courte (8 vs 13 jours, p<0.001). La reprise du transit a été plus rapide après laparoscopie, mais uniquement après intervention sur le colon gauche (3 vs 4 jours, p<0.01). Cependant, la sélection préopératoire (nombre plus élevé d'urgences et de patients avec un risque anesthésiologique élevé dans le groupe de la chirurgie ouverte) a été favorable à la laparoscopie. Le taux de complications (global ainsi que pour chaque complication chirurgicale) a été similaire dans les deux groupes, avec un taux global de 20% environ. Conclusions: Malgré une sélection favorable des cas, uniquement très peu d'avantages à la laparoscopie sur la chirurgie ouverte ont pu être observés. Abstract Background: Most studies available on laparoscopic colorectal surgery focus on highly selected patient groups. The aim of the present study was to review short- and long-term outcome of everyday patients treated in a general surgery department. Methods: Retrospective review was carried out of a prospective database of all consecutive patients having undergone primary laparoscopic (LAP) or open colorectal surgery between March 1993 and December 1997. Follow-up data were completed via questionnaire. Results: A total of 187 patients underwent LAP resection and 215 patients underwent open surgery. Follow up was complete in 95% with a median of 59 months (range, 1-107 months) and 53 months (range, 1-104 months), respectively. There were 28 conversions (15%) in the LAP group and these remained in the LAP group in an intention-to-treat analysis. The LAP operations lasted significantly longer for all types of resections (205 vs 150 min, P<0.001) and hospital stay was shorter (8 vs 13 days, P<0.001). Recovery of intestinal function was faster in the LAP group, but only after left-sided procedures (3 vs 4days, P<0.01). However, preoperative patient selection (more emergency operations and patients with higher American Society of Anesthesiologists (ASA) score in the open group) had a major influence on these elements and favours the LAP group. Surprisingly, the overall surgical complication rate (including long-term complications such as wound hernia) was 20% in both groups with rates of individual complications also being comparable in both groups. Conclusion: Despite a patient selection favourable to the laparoscopy group, only little advantage in postoperative outcome could be shown for the minimally invasive over the open approach in the everyday patient.

Interaction between Musca domestica L. and its predator Muscina stabulans (Fallén) (Diptera, Muscidae): effects of prey density and food source abundance

Interaction between Musca domestica L. and its predator Muscina stabulans (Fallén) (Diptera, Muscidae): Effects of prey density and food source abundance. The objective of this work was to evaluate the influence of prey density and food source abundance on the predatory behavior of Muscina stabulans over M. domestica. Three predator/prey proportions were evaluated (1:1, 1:3 and 1:6), using 100 third instar predator larvae against second instar prey larvae. Each proportion was maintained using three different levels of food substrate (25, 50 and 100 g). The experiments were carried out in triplicate in BOD incubators (25ºC, UR 70% ± 10% and 12 h photoperiod). The mortality of the M. domestica larvae was 100% under all conditions, except in the 1:6 predator/prey proportion, at the 50g and 100g food substrate levels, where it was 99.99% and 99.22%, respectively. There was a significant increase in the development period of M. stabulans in relation to the increase in prey density and decrease in quantity of food substrate. An increase in the proportion of individuals and a reduction in the amount of resource slowed down larval development. Muscina stabulans pupal weight was proportional to the increase in prey density and the amount of food substrate. The proportion or the density influenced the survival of M. stabulans, with no difference in relation to the amount of food source and consequently in the interaction of the factors. There was no difference between the 1:1 and 1:3 predator-prey densities, with both differing from the 1:6 density.

Este trabalho foi realizado no âmbito dos regulamentos dos cursos de graduação para a obtenção do grau de licenciatura na universidade Jean Piaget de Cabo Verde. Nele abordamos os conceitos de Bussines Process Management (BPM), Bussines Process Automation (BPA) e Open Source, cujo seu principal objectivo é dar a conhecer o estudo e implementação de automatização de processo de negócio usando ferramentas de BPM Open Source e o seu impacto depois da implementação. No presente trabalho fez-se uma investigação sobre algumas ferramentas Open Source usadas na automatização de processos de negócio, e implementado um processo BPM no framework Activiti para automatização do processo de negócio segunda via dos números dos clientes da Unitel T+. Para a automatização do processo Segunda Via foi integrado os frameworks Activiti e o Liferay, visto que dado a realidade de uma operadora de telecomunicação existe uma plataforma de gestão dos dados dos clientes implementado no Liferay, e havia necessidade de integrar estes dois frameworks distintos. Um dos maiores desafios na integração dos dois frameworks foi a autenticação. Para dar resposta a este problema, obter maior nível de segurança e sincronizar os frameworks foi utilizado o Hook que permite uma única autenticação e balanceamento (sincronização) dos dados no Activiti e no Liferay.

ET-1 and NOS III gene expression regulation by plaque-free and plaque-prone hemodynamic conditions

Résumé: Les environnements hémodynamiques, favorisant ou protégeant contre la formation de la plaque, induisent tout deux une augmentation de la production d'anion superoxide dans les cellules endothéliales (ECs). Par ailleurs, une régulation différente de l'expression des gènes a été décrite dans les cellules exposées à ces différentes conditions. Dans le but d'investiguer le rôle de l'augmentation du stress oxydatif dans l'expression des gènes régulée par le flux, nous avons d'abord exposé les EC à un flux unidirectionnel, non pulsé. Dans ces conditions, l'état oxydatif des cellules endothéliales est augmenté de façon transitoire. L'expression du gène de l'endothéline 1 (ET-1) est aussi induite de façon transitoire par un tel flux, alors que l'expression du gène de la nitiric oxyde synthase endothéliale (NOS III) est stimulé de façon durable. Au contraire, un flux unidirectionnel pulsé, qui induit une augmentation durable de la production d'anion superoxide, augmente aussi de façon durable l'expression des gènes de ET-1 comme de NOS III. Un flux oscillatoire (favorisant la plaque), qui lui aussi ,a des effets à long terme sur la production d'anion superoxide, a uniquement augmenté l'expression de ET-1. De plus, l'utilisation d'un antioxydant, a seulement partiellement inhibé la stimulation de l'expression du gène NOS III par le flux unidirectionnel pulsé, alors qu'il a complètement abrogé la stimulation de l'expression du gène ET-1 par le flux unidirectionnel pulsé et oscillatoire. Ceci suggère que les forces mécaniques régulent l'expression des gènes dans les EC par un double mécanisme dépendant et indépendant du stress oxidatif des cellules. Par ailleurs, ces résultats supportent ultérieurement l'hypothèse que la balance entre la réponse oxidative et anti-oxidante dans les cellules endothéliales exposées à un environnement hémodynamique est une des clés de la prédisposition à un dysfonctionnement endothélial observé dans des régions exposées à des flux perturbés. Abstract: Both plaque-free and plaque-prone hemodynamic environments induce an increase in the oxidative state of endothelial cells (ECs), whereas differential gene expression regulation was described in cells exposed to these conditions. In order to investigate the role of the increased oxidative state in flow-regulation of gene expression, we first exposed EC to non-pulsed unidirectional shear stress. These conditions only slightly increases ECs oxidative state and endothelin-1 (ET-1) mRNA expression, whereas endothelial nitric oxide synthase (NOS III) mRNA level were significantly up-regulated. On the contrary, both ET-1 and NOS III gene expression were significantly induced in EC exposed to pulsed-unidirectional flow (plaque-free). Only ET-1 gene expression was up-regulated by oscillatory flow (plaque-prone). Moreover, use of an antioxidant only partially inhibited NOS III gene up-regulation by unidirectional flow, whereas it completely abrogated ET-1 gene up-regulation by unidirectional and oscillatory flows. Thus suggesting that mechanical forces regulate gene expression in ECs both via oxidative stress-dependent and -independent mechanisms.
