Caractérisation des unités de soins aigus chirurgicaux au sein des départements de chirurgie générale au Canada

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.

Étude sur le rôle de SIGIRR chez les cas pédiatriques dans la maladie de Crohn.

Il est admis que la maladie de Crohn (MC) résulte de facteurs immunologiques, environnementaux et génétiques. SIGIRR, un récepteur anti-inflammatoire, n’a jamais été étudié dans le contexte de la MC, et de nombreuses découvertes à son sujet ont mené plusieurs à s’intéresser quant à son utilité dans l’atténuation de maladies inflammatoires. Récemment, l’IL-37 a été identifié comme ligand d’un complexe formé de SIGIRR-IL-18Rα. SIGIRR et l’IL-37 pourraient alors être des acteurs de la dérégulation de l’inflammation retrouvée chez la MC. Nous les avons étudiés dans le contexte de la MC pédiatrique, afin d’y caractériser leurs effets. Nous avons identifié une diminution de l’expression de SIGIRR sur certains types de cellules immunitaires. De plus, les personnes atteintes de la MC ont des concentrations de protéines altérées, soit SIGIRR soluble, l’IL-37, l’IL-18BP, et l’IL-18, et tendent à revenir à la normale lorsque l’inflammation est contrôlée par médication. De plus, la concentration de l’IL-18 libre suit le même patron. Par analyse de régression linéaire de SIGIRR soluble et l’IL-37, de l’IL-18BP et l’IL-18, ainsi que l’IL-37 et l’IL-18, des tendances divergentes ont été identifiées entre les patients non traités aux contrôles et patients traités. Nos résultats suggèrent que le système IL-37-SIGIRR est compromis chez les patients de la MC. Étant donné que ce système est un facteur crucial dans la régulation négative de l’inflammation, il sera intéressant de déterminer si SIGIRR et l’IL-37 peuvent constituer des cibles thérapeutiques importantes dans l’atténuation et la résolution de l’inflammation chez les patients atteints de la MC.

Health-related quality of life in Huntington's disease: a comparison of two generic instruments, SF-36 and SIP

Whereas several clinical endpoints in monitoring the response to treatment in patients with Huntington's disease (HD) have been explored, there has been a paucity of research in the quality of life in such patients. The aim of this study was to validate the use of two generic health-related quality of life instruments (the Short Form 36 health survey questionnaire [SF-36] and the Sickness Impact Profile [SIP]) and to evaluate their psychometric properties. We found that both instruments demonstrated acceptable convergent validity and reliability for patients and carers. However, there was an advantage in using the SF-36 because of its more robust construct validity and test-retest reliability; furthermore, motor symptoms appeared to influence some strictly nonmotor dimensions of the SIP. On a pragmatic level, the SF-36 is shorter and quicker to administer and, therefore, easier for patients at various stages of the disease to complete. Thus, the SF-36 would appear to be the recommended instrument of choice for patients with HD and their carers, although further work needs to be done to investigate the sensitivity of this instrument longitudinally.

A controlled trial of sip-feed supplements in elderly orthopaedic patients

The potential nutritional and clinical benefits of sip-feed supplements were investigated by means of a controlled trial in elderly female patients admitted for orthopaedic surgery. A nutritional risk assessment procedure (Nutritional Risk Questionnaire, NRQ) was used to identify patients who might benefit from supplementation. Patients identified as high risk who did not receive supplements showed significant losses in triceps skinfold thickness (TSF) and mid-upper arm muscle circumference (MUAMC) measurements during hospitalization. Such changes were not observed in high-risk supplemented patients, but significant losses of MUAMC were also recorded in a group of patients who failed to comply with the supplement. No differences in biochemical parameters, muscle function, or clinical outcome were observed between supplemented and unsupplemented and non-compliant patients. The problems of poor compliance to sip-feed supplements and failure to observe clinical benefit in supplemented patients are discussed.

Établir des priorités en soins de santé. Comment passer des besoins vitaux aux taux de remboursement?

Choisir est consubstantiel à l’existence humaine, mais dans le cadre de biens collectifs comme les soins de santé, dans le cadre de budgets forcément limités et objet de réduction, choisir devient un devoir éthique. Nous proposons une approche susceptible d’être féconde dans la détermination du « paquet de soins ». Cette approche est fondée sur le concept de « besoin vital » qui doit être rencontré afin d’éviter un « endommagement grave » qui altère la capacité d’agent de la personne. Nous formulons ensuite une critique de la plupart des variables focales, qui déterminent chacune une forme d’égalitarisme, avant de considérer quelques questions éthiques liées à la fixation de priorités en santé. La prise en considération des préférences de la population apparaît comme un élément incontournable à la légitimation des décisions. Elle peut s’avérer féconde si elle bénéficie d’une forme de care que nous qualifions d’informationnel.

An Upgrade of Network Traffic Recognition System for SIP/VoIP Traffic Recognition

The purpose of this project is to update the tool of Network Traffic Recognition System (NTRS) which is proprietary software of Ericsson AB and Tsinghua University, and to implement the updated tool to finish SIP/VoIP traffic recognition. Basing on the original NTRS, I analyze the traffic recognition principal of NTRS, and redesign the structure and module of the tool according to characteristics of SIP/VoIP traffic, and then finally I program to achieve the upgrade. After the final test with our SIP data trace files in the updated system, a satisfactory result is derived. The result presents that our updated system holds a rate of recognition on a confident level in the SIP session recognition as well as the VoIP call recognition. In the comparison with the software of Wireshark, our updated system has a result which is extremely close to Wireshark’s output, and the working time is much less than Wireshark. In the aspect of practicability, the memory overflow problem is avoided, and the updated system can output the specific information of SIP/VoIP traffic recognition, such as SIP type, SIP state, VoIP state, etc. The upgrade fulfills the demand of this project.

Uma arquitetura baseada em SCTP e SIP para suporte a aplicações VoIP móveis e a especificação formal do seu módulo de controle

New versions of SCTP protocol allow the implementation of handover procedures in the transport layer, as well as the supply of a partially reliable communication service. A communication architecture is proposed herein, integrating SCTP with the session initiation protocol, SIP, besides additional protocols. This architecture is intended to handle voice applications over IP networks with mobility requirements. User localization procedures are specified in the application layer as well, using SIP, as an alternative mean to the mechanisms used by traditional protocols, that support mobility in the network layer. The SDL formal specification language is used to specify the operation of a control module, which coordinates the operation of the system component protocols. This formal specification is intended to prevent ambiguities and inconsistencies in the definition of this module, assisting in the correct implementation of the elements of this architecture
