Les comportements face au VIH/sida des hommes qui ont des rapports sexuelles avec des hommes : Enquête Gaysurvey 2014

Depuis 1987, Gaysurvey est une enquête menée périodiquement en Suisse parmi les hommes qui ont des relations sexuelles avec des hommes (HSH). Elle s'inscrit dans le dispositif de surveillance du VIH, établi par l'Office fédéral de la santé publique, en tant qu'instrument de suivi des comportements face au VIH/Sida dans ce groupe-cible. Elle a déjà été réalisée à dix reprises. L'enquête Gaysurvey 2014 était disponible en ligne sur Internet et consistait en un questionnaire anonyme auto-administré. Le nombre de participant est de 834 personnes. Pour sa onzième édition, Gaysurvey reste un instrument pertinent du suivi des comportements des HSH face au VIH/Sida. Certaines tendances observées ces dernières années ont été confirmées, de nouveaux thèmes ont été abordés et de nouveaux éléments de réflexions apportés.

Alterações incidentais dos seios da face na tomografia computadorizada do crânio e órbitas em crianças

OBJETIVO: Avaliar a prevalência e as características das alterações tomográficas incidentais dos seios da face em crianças sem quadro clínico de rinossinusite. MATERIAIS E MÉTODOS: Foram estudados pacientes entre zero e 18 anos de idade, submetidos a tomografia computadorizada do crânio ou órbitas por indicações não relacionadas a doença sinusal. RESULTADOS: Foram incluídas 64 crianças (idade média = 5,7 anos; desvio-padrão = 3,9). Achados incidentais nos seios da face ocorreram em 46 casos (72%). Na maioria (25/46) as alterações eram discretas e o espessamento mucoso foi o achado incidental mais comum. Opacificação completa ou nível líquido foram observados em 12 crianças. Mais de um seio foi afetado em 33 pacientes, ocorrendo com maior freqüência nos seios maxilares, seguidos dos etmoidais. O acometimento bilateral e simétrico foi comum. As anormalidades ocorreram com maior prevalência, intensidade e extensão em crianças abaixo de três anos de idade. CONCLUSÃO: A prevalência de alterações tomográficas incidentais em crianças sem quadro clínico de rinossinusite é alta, predominando as definidas como discretas. A alteração mais encontrada é o espessamento mucoso. Achados incidentais moderados e acentuados tendem a ocorrer em crianças com menos de três anos de idade.

Impact of a Dedicated Noninvasive Ventilation Team on Intubation and Mortality Rates in Severe COPD Exacerbations.

BACKGROUND: Compared with usual care, noninvasive ventilation (NIV) lowers the risk of intubation and death for subjects with respiratory failure secondary to COPD exacerbations, but whether administration of NIV by a specialized, dedicated team improves its efficiency remains uncertain. Our aim was to test whether a dedicated team of respiratory therapists applying all acute NIV treatments would reduce the risk of intubation or death for subjects with COPD admitted for respiratory failure. METHODS: We carried out a retrospective study comparing subjects with COPD admitted to the ICU before (2001-2003) and after (2010-2012) the creation of a dedicated NIV team in a regional acute care hospital. The primary outcome was the risk of intubation or death. The secondary outcomes were the individual components of the primary outcome and ICU/hospital stay. RESULTS: A total of 126 subjects were included: 53 in the first cohort and 73 in the second. There was no significant difference in the demographic characteristics and severity of respiratory failure. Fifteen subjects (28.3%) died or had to undergo tracheal intubation in the first cohort, and only 10 subjects (13.7%) in the second cohort (odds ratio 0.40, 95% CI 0.16-0.99, P = .04). In-hospital mortality (15.1% vs 4.1%, P = .03) and median stay (ICU: 3.1 vs 1.9 d, P = .04; hospital: 11.5 vs 9.6 d, P = .04) were significantly lower in the second cohort, and a trend for a lower intubation risk was observed (20.8% vs 11% P = .13). CONCLUSIONS: The delivery of NIV by a dedicated team was associated with a lower risk of death or intubation in subjects with respiratory failure secondary to COPD exacerbations. Therefore, the implementation of a team administering all NIV treatments on a 24-h basis should be considered in institutions admitting subjects with COPD exacerbations.

Les équipes cyclistes « professionnelles » face aux nouvelles injonctions au professionnalisme

La médiatisation des affaires de dopage a rendu accessibles au public les coulisses de la production de la performance des cyclistes. Confrontées à des contraintes de visibilité de leurs pratiques, les équipes doivent désormais produire des performances crédibles tout en affirmant une identité professionnelle acceptable. Les équipes du cyclisme professionnel sont inégalement armées pour faire face à cette nouvelle donne. Celles qui disposent de ressources technoscientifiques importantes, sont adossées à des sponsors aux visées mondiales, et sont moins liées à leurs ancrages territoriaux, s'y adaptent plus facilement. Certaines de ces équipes mondialisées font évoluer les normes de production de la performance ; elles contribuent ainsi à réduire l'autonomie du travail des autres équipes et modifient ce que signifie être une équipe professionnelle.

Décision de baisser les salaires ou non: Le rôle de l'empathie face à une recommandation d'un supérieur hiérarchique (The role of Empathy in wage cut decisions).

En entreprise, les supérieurs hiérarchiques ont une influence non négligeable sur la prise de décision de leurs subordonnés. Ces derniers tendent à se conformer à l'avis de leur supérieur pour prendre leurs décisions. Toutefois, cette conformité des subordonnés à l'avis de leur supérieur peut devenir un problème lorsque l'avis reçu est questionnable d'un point de vue éthique. Les études antérieures menées à ce sujet ont démontré que le contenu n'a pas d'impact, c'est-à-dire que du moment qu'un avis est donné par un supérieur hiérarchique, les subordonnés tendent à se conformer à cet avis quelque soit son contenu. Dans la présente expérience, nous nous sommes intéressés à ce phénomène de conformité dans une prise de décision ayant des conséquences sur des personnes. En particulier, nous avons étudié le rôle de l'empathie, définit comme l'habilité de ressentir les émotions des autres ou de se mettre à leur place. Notre première hypothèse concerne l'effet principal de l'avis du supérieur : les participants tiennent compte de l'avis de leur supérieur dans leur prise de décision. Notre seconde hypothèse concerne le rôle modérateur de l'empathie: les participants haut en empathie sont moins sensibles à l'avis de leur supérieur que les participants bas en empathie étant donné qu'ils anticipent les conséquences de leur décision vis-à-vis des personnes concernées. Cent-douze étudiants ont participé à un exercice de mise en situation. Dans la peau d'un chef de Département d'une entreprise, ils devaient entre autres réfléchir au problème du niveau des salaires du personnel peu qualifié et en particulier au fait que cette catégorie de salariés était surpayée par rapport à ce qui se pratiquait sur le marché du travail. Cette expérience était composée de deux conditions, où l'avis du supérieur était manipulé. Dans la condition 1, l'avis du supérieur était de baisser les salaires, alors que dans la condition 2 l'avis était de garder les salaires constants. Les résultats ont confirmé nos hypothèses. Les participants recevant l'avis de leur supérieur de baisser les salaires ont effectivement pris la décision de baisser les salaires. Il a aussi été démontré que le niveau d'empathie modère cette relation. Les participants haut en empathie ont eu tendance à ne pas suivre l'avis donné contrairement aux participants bas en empathie. Cela démontre ainsi l'influence que peut avoir le contexte sur les individus et leur prise de décision mais aussi que les caractéristiques personnelles ont une influence non négligeable.

Entraînement à faire face au stress professionnel pour les personnes avec un retard intellectuel : une étude pilote / Training to cope with workplace stress for people with mild intellectual disability: a pilot study

Cette étude pilote cherche à tester la faisabilité de l'entraînement à la cohérence cardiaque avec des personnes atteintes d'un retard intellectuel dans le cadre d'un atelier protégé. Un entraînement à la cohérence cardiaque est proposé aux participants volontaires pour une durée de deux semaines à la prise de travail, matin et après-midi. Une appréciation des effets de ces exercices respiratoires est effectuée avant et après entraînement par la mesure d'indices de variabilité cardiaque et une évaluation de la perception du stress professionnel. La comparaison des valeurs récoltées pré et post-entraînement révèle une amélioration significative dans l'activation de la branche parasympathique. L'évaluation des valeurs du RMSSD sont inversement corrélées à l'évaluation des participants de leurs stress perçu. Ensemble, nos résultats indiquent que la population atteinte de retard intellectuel est réceptive à l'apprentissage de la cohérence cardiaque et que la baisse de leur stress est liée à une hausse de l'activité inhibitrice parasympathique, plutôt qu'à une diminution de l'activité excitatrice sympathique. Les considérations offertes par cette étude exploratoire doivent être étayées, mais permettent d'ores et déjà d'ouvrir de nouvelles perspectives dans la prise en charge de populations pour lesquelles la gestion du stress est mal adaptée.

Radioproteção, dose e risco em exames radiográficos nos seios da face de crianças, em hospitais de Belo Horizonte, MG

OBJETIVO: Avaliar a freqüência das incidências radiográficas realizadas nos seios da face de pacientes pediátricos em hospitais de Belo Horizonte, MG, as condições de radioproteção, as técnicas radiográficas empregadas, o kerma no ar de entrada e as doses nos órgãos mais expostos. MATERIAIS E MÉTODOS: Foram coletados os dados dos pacientes e parâmetros de técnica radiográfica empregados em exames de crianças de 1 a 16 anos de idade, em cinco salas de quatro hospitais da cidade, observando, também, aspectos de proteção radiológica. O kerma no ar de entrada foi estimado a partir dos rendimentos dos tubos de raios-x e as doses nos órgãos utilizando o software PCXMC. RESULTADOS: Os valores médios do kerma no ar de entrada para as cinco salas foram, respectivamente, 1.398 µGy, 829 µGy, 877 µGy, 1.168 µGy e 3.886 µGy para pacientes entre 1 e 5 anos de idade. CONCLUSÃO: Foi constatado que as incidências mento-naso e fronto-naso são comumente solicitadas em conjunto, na maioria dos hospitais, o que confere dose significativa para os pacientes. Os riscos para os pacientes podem ser diminuídos mediante a utilização de cilindros de colimação, a não-utilização de grades antiespalhamento, o emprego de altos valores de tensão e baixos valores de tempo.

Association of Hematological Variables with Team-Sport Specific Fitness Performance.

PURPOSE: We investigated association of hematological variables with specific fitness performance in elite team-sport players. METHODS: Hemoglobin mass (Hbmass) was measured in 25 elite field hockey players using the optimized (2 min) CO-rebreathing method. Hemoglobin concentration ([Hb]), hematocrit and mean corpuscular hemoglobin concentration (MCHC) were analyzed in venous blood. Fitness performance evaluation included a repeated-sprint ability (RSA) test (8 x 20 m sprints, 20 s of rest) and the Yo-Yo intermittent recovery level 2 (YYIR2). RESULTS: Hbmass was largely correlated (r = 0.62, P<0.01) with YYIR2 total distance covered (YYIR2TD) but not with any RSA-derived parameters (r ranging from -0.06 to -0.32; all P>0.05). [Hb] and MCHC displayed moderate correlations with both YYIR2TD (r = 0.44 and 0.41; both P<0.01) and RSA sprint decrement score (r = -0.41 and -0.44; both P<0.05). YYIR2TD correlated with RSA best and total sprint times (r = -0.46, P<0.05 and -0.60, P<0.01; respectively), but not with RSA sprint decrement score (r = -0.19, P>0.05). CONCLUSION: Hbmass is positively correlated with specific aerobic fitness, but not with RSA, in elite team-sport players. Additionally, the negative relationships between YYIR2 and RSA tests performance imply that different hematological mechanisms may be at play. Overall, these results indicate that these two fitness tests should not be used interchangeably as they reflect different hematological mechanisms.

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.

Screening of mental health and substance users in frequent users of a general Swiss emergency department.

BACKGROUND: The objectives of this study were to determine the proportions of psychiatric and substance use disorders suffered by emergency departments' (EDs') frequent users compared to the mainstream ED population, to evaluate how effectively these disorders were diagnosed in both groups of patients by ED physicians, and to determine if these disorders were predictive of a frequent use of ED services. METHODS: This study is a cross-sectional study with concurrent and retrospective data collection. Between November 2009 and June 2010, patients' mental health and substance use disorders were identified prospectively in face-to-face research interviews using a screening questionnaire (i.e. researcher screening). These data were compared to the data obtained from a retrospective medical chart review performed in August 2011, searching for mental health and substance use disorders diagnosed by ED physicians and recorded in the patients' ED medical files (i.e. ED physician diagnosis). The sample consisted of 399 eligible adult patients (≥18 years old) admitted to the urban, general ED of a University Hospital. Among them, 389 patients completed the researcher screening. Two hundred and twenty frequent users defined by >4 ED visits in the previous twelve months were included and compared to 169 patients with ≤4 ED visits in the same period (control group). RESULTS: Researcher screening showed that ED frequent users were more likely than members of the control group to have an anxiety, depressive disorder, post-traumatic stress disorder (PTSD), or suffer from alcohol, illicit drug abuse/addiction. Reviewing the ED physician diagnosis, we found that the proportions of mental health and substance use disorders diagnosed by ED physicians were low both among ED frequent users and in the control group. Using multiple logistic regression analyses to predict frequent ED use, we found that ED patients who screened positive for psychiatric disorders only and those who screened positive for both psychiatric and substance use disorders were more likely to be ED frequent users compared to ED patients with no disorder. CONCLUSIONS: This study found high proportions of screened mental health and/or substance use disorders in ED frequent users, but it showed low rates of detection of such disorders in day-to-day ED activities which can be a cause for concern. Active screening for these disorders in this population, followed by an intervention and/or a referral for treatment by a case-management team may constitute a relevant intervention for integration into a general ED setting.

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.
