Risques et bénéfices d'une approche interventionnelle face aux corps étrangers digestifs [Digestive foreign body management].

Foreign body (FB) ingestion is a frequent reason for gastroenterology consulting. Eighty percent of these ingestions are accidental and observed among paediatric subjects. However, intentional repetitive ingestions are also observed, especially amongst prisoners or psychiatric patients. Most FBs pass throughout the digestive tract without any complication and without any need for surgical or endoscopic intervention. Nevertheless, around 10-20% of cases require an endoscopy examination and 1% will lead to a surgical intervention. Management approaches should favor inter-disciplinarity, balance benefits and risks of FB removal based on its location, and integrate psychiatric comorbidities into the decision process.

Avaliação da exposição dos médicos à radiação em procedimentos hemodinâmicos intervencionistas

OBJETIVO: Este trabalho avalia a distribuição de dose recebida por médicos envolvidos em procedimentos hemodinâmicos de angioplastia coronária e coronariografia. A influência de alguns fatores, como o modo de fluoroscopia pulsado ou contínuo e o local de acesso à veia e/ou artéria, foi investigada. MATERIAIS E MÉTODOS: Para esta avaliação foram feitas medições utilizando dosímetros termoluminescentes de LiF:Mg,Ti, posicionados em sete diferentes pontos do corpo dos profissionais: mãos, joelho, pescoço, testa e tórax, por dentro e por fora do avental de chumbo. A dose foi avaliada, por exame, nos médicos que executaram os procedimentos (30 de angioplastia e 60 de coronariografia). Os dosímetros termoluminescentes foram calibrados na grandeza operacional equivalente de dose pessoal, Hp(d), nas profundidades de 0,07, 3 e 10 mm. RESULTADOS: Os resultados mostram a importância do uso do protetor de tireóide e avental de chumbo para a redução da dose recebida pelos médicos. As doses dos profissionais que executaram procedimentos por via braquial usando modo contínuo de fluoroscopia foram mais altas do que os que executaram por via femoral e modo pulsado de fluoroscopia. CONCLUSÃO: Este estudo mostra a necessidade de medidas adicionais de proteção e a implementação de mecanismos de treinamento em proteção radiológica para os médicos que trabalham com cardiologia intervencionista.

The Changing Face of Psychiatric Nursing –Care or Control?

This report has been written as part of the project “Toward improved quality – developing nurse’s continuing vocational training in hospitals and inpatient units”. Its overall goal is to ensure high quality, ethically appropriate and therapeutically effective interventions to enable nurses to manage distressed and disturbed patients in European psychiatric hospitals and inpatient units. In this large-scale, multinational projects there are all together six European countries involved: Finland, Ireland, England, Portugal, Italy and Lithuania. The project work plan were during autumn 2006 and spring 2007. The content of this publication was produced in the first stage of the project aiming to collect the preliminary source material for the project. The literature review was carried out in the project stage, providing the groundwork for the next steps for the project. This project aims to develop an interactive multinational portal with training material. Therefore, it is important to share an understanding of basic information, psychiatric nurse’s continuing vocational education, laws and ethical codes and patient restriction used in mental health care. In this publication, the purpose of the material produced here is to understand nurses’ educational need related to vocational continuing education and to be used in further project stages as an empirical data collection. The data were collected as a preliminary source material for latter phases where nurse’s perceptions of the current practice, nurse’s attitudes to mental illness, prevalence of use of seclusion room and existing and desired vocational training provision will be collected in six different European countries. The following organisations are involved in this project: University of Turku, Dublin City University, St. Vincent Hospital, National Council for the Professional Development of Nursing and Midwifery, University of Padova, Klaipeda College - Health Faculty, Klaipeda Psychiatric Hospital, Escola Superior de Enfermagem de Lisboa, Centro Hospitalar Psiquiátrico de Lisboa, Omnia Vocational Institution the Espoo Region, Kellokoski psychiatric hospital, Hyvinkää hospital area, Pirkanmaa Hospital District, Kingston University & St. George’s Medical School and South West London & St. George’s Mental Health NHS Trust. A wide variety of different countries, organisations and individuals in this project give us a strong confidence that theoretical, practical, ethical and political issues around the topic of interest will be taken account during this project lifetime. We are aware the content of this book will be partially outdated almost as soon as it has been published. We still hope that this publication will encourage nurses and different professions working in mental health care field to have a basic understanding of similarities and differences between different European countries related in mental health care. We also hope that this publication will inspirate and motivate nurses in maintaining and developing the quality of psychiatric care in Europe.

Le rôle des associations de patients face au don d'organes en Suisse romande [Organ donation and the role of patients' associations in Western Switzerland].

In the context of lay mobilization in health-related areas, this article addresses the role and activities of patients' associations in connection with organ donation, on the basis of interviews carried out with thirty members of transplant patients' associations in the French-speaking part of Switzerland. First, we describe the three main categories of activities conducted by these associations. While self-help and public awareness activities are predominant, policy-oriented actions are marginal. Then, we examine the factors likely to explain why these associations have a limited capacity to be active, especially in the public sphere. Such a lack of social visibility is all the more important in the current political context, characterized by the implementation of a national action plan designed to improve organ donation.

Current Sheet Regulation of Solar Near-Relativistic Electron Injection Histories

We present a sample of three large near-relativistic (>50 keV) electron events observed in 2001 by both the ACE and the Ulysses spacecraft, when Ulysses was at high-northern latitudes (>60°) and close to 2 AU. Despite the large latitudinal distance between the two spacecraft, electrons injected near the Sun reached both heliospheric locations. All three events were associated with large solar flares, strong decametric type II radio bursts and accompanied by wide (>212°) and fast (>1400 km s-1) coronal mass ejections (CMEs). We use advanced interplanetary transport simulations and make use of the directional intensities observed in situ by the spacecraft to infer the electron injection profile close to the Sun and the interplanetary transport conditions at both low and high latitudes. For the three selected events, we find similar interplanetary transport conditions at different heliolatitudes for a given event, with values of the mean free path ranging from 0.04 AU to 0.27 AU. We find differences in the injection profiles inferred for each spacecraft. We investigate the role that sector boundaries of the heliospheric current sheet (HCS) have on determining the characteristics of the electron injection profiles. Extended injection profiles, associated with coronal shocks, are found if the magnetic footpoints of the spacecraft lay in the same magnetic sector as the associated flare, while intermittent sparse injection episodes appear when the spacecraft footpoints are in the opposite sector or a wrap in the HCS bounded the CME structure.

Sentiment de finitude de vie et de coping chez le patient face à l'annonce d'un cancer digestif étude descriptive correlationnelle

Problématique. Le cancer digestif est une maladie qui s'accompagne de nombreux décès. L'annonce d'un tel diagnostic engendre une crise existentielle composée d'un sentiment de finitude de la vie. Des réactions psychosociales accompagnent cette mauvaise nouvelle. Un concept particulier appelé le transitoriness est omniprésent. La personne lutte pour continuer à vivre. Elle adopte des stratégies de coping pour s'ajuster aux difficultés imposées par ce sentiment de finitude de vie. But. Décrire le niveau de sentiment de finitude de vie et les stratégies de coping utilisées face à l'annonce du diagnostic d'un cancer digestif et explorer la présence d'associations entre les variables. Méthode. Cette étude descriptive corrélationnelle a été conduite auprès de 40 personnes hospitalisées pour une intervention chirurgicale, recrutées selon un échantillonnage de convenance. Le protocole de recherche a été avalisé par le comité cantonal d'éthique. Les données ont été recueillies par un formulaire de données sociodémographiques et de santé ainsi que deux instruments de mesure : le SEKT (Subjektive Einschätzung von Krankheitssituation und Todesnähe) a permis de mesurer le sentiment de finitude de vie et le JCS (Jalowiec Coping Scale) a été employé pour recueillir les stratégies de coping. Les deux instruments de mesure n'étant pas disponibles en français, une procédure de traduction et retraduction a été effectuée et avalisée par un comité d'expert. Des analyses descriptives et corrélationnelles ont été réalisées. Résultats. L'échantillon est composé majoritairement d'hommes (51%), âgés entre 56- 74 ans (52,5%), mariés (45%) et avec enfants âgés de plus de 20 ans (60%). Il apparaît une forte proportion de personnes d'une autre nationalité (40%) que la suisse et avec une formation obligatoire (40%). Le sentiment de finitude de vie est présent: 62% réalisent que le cancer représente une menace pour leur vie. Les préoccupations autour de la mort sont « quelquefois » présentes (32,5%). Les personnes se sentent « un peu » à « proche » de la mort et le score total de la proximité est de M = 3,37 (ĒT= 1,77 ; rang: 0-8). Le style de coping privilégié est l'optimisme (M = 2,10), puis l'indépendance (M = 1,95) et l'affrontement de la situation (M =1,80). Aucune relation entre le sentiment de finitude de vie et le score total de coping n'apparaît, si ce n'est une probabilité p< 0,08 entre le sentiment de finitude de vie et les styles de coping expression des émotions et indépendance. La relation entre le sentiment de finitude de vie et la variable sociodémographique la nationalité présente une probabilité marginale (p= 0,058). Certains facteurs sociodémographiques influencent l'utilisation des différentes stratégies de coping : affrontement de la situation (p= 0,0007), coping palliatif (p= 0,0449) et niveau de formation; optimisme et genre (p= 0,0424) ; expression des émotions et âge (p= 0,045); indépendance et nationalité (p= 0,0319); soutien social et nombre d'enfants (p= 0,0016). Conclusion. Les professionnels de la santé doivent être sensibilisés aux spécificités du transitoriness et aux facteurs influençant l'utilisation de stratégies de coping efficaces afin de détecter les personnes vulnérables et de cibler leurs interventions de soins pour diminuer le risque de détresse et son impact sur la qualité de vie du patient.

Shared feature extraction for nearest neighbor face recognition

In this paper, we propose a new supervised linearfeature extraction technique for multiclass classification problemsthat is specially suited to the nearest neighbor classifier (NN).The problem of finding the optimal linear projection matrix isdefined as a classification problem and the Adaboost algorithmis used to compute it in an iterative way. This strategy allowsthe introduction of a multitask learning (MTL) criterion in themethod and results in a solution that makes no assumptions aboutthe data distribution and that is specially appropriated to solvethe small sample size problem. The performance of the methodis illustrated by an application to the face recognition problem.The experiments show that the representation obtained followingthe multitask approach improves the classic feature extractionalgorithms when using the NN classifier, especially when we havea few examples from each class
