Noces : un dispositif complexe et une réception plurivoque

Noces est un film réalisé par Philippe Béziat. Issu d'une coproduction franco-suisse, il est sorti en France le 8 février 2012 et en Suisse romande le 26 septembre de la même année. Il met en scène, dans le Lavaux, une production contemporaine de l'oeuvre Les Noces, des répétitions à la présentation de la pièce dans son intégralité. La particularité de cette représentation, qui constitue l'aboutissement du film, réside dans le fait qu'elle n'est pas jouée devant un public, et était d'emblée prévue pour être exclusivement filmée1. Cette «cantate-ballet» a été composée par Igor Stravinsky lors de son séjour à Morges et le livret a été adapté en français par Charles-Ferdinand Ramuz à partir de contes et chansons populaires russes. La création du spectacle est encadrée par les Souvenirs sur Igor Strawinsky2, ouvrage dans lequel le poète vaudois évoque sa collaboration avec le compositeur et dépeint le lieu où ce projet a été développé. Constatant la diversité des discours critiques portés sur le film lors de sa sortie, le présent article cherche à identifier les logiques de réception ainsi que les aspects du film qui, parce que susceptibles de produire des lectures plurivoques, peuvent conduire à élaborer des avis opposés. 1Philippe Béziat revendique cette particularité de Noces dans l'interview qui figure dans le dossier de presse du film : « Mais le dispositif de représentation est absolument unique et ne peut être que cinématographique. On ne peut pas imaginer donner ces Noces comme ça dans une salle de concert ou dans une salle d'opéra. On n'entendrait pas ce que le spectateur du film entend, avec un son direct, spatialisé, et toujours du point de vue de la caméra. Un point de vue idéal parce qu'au centre de tout. ». 2Charles-Ferdinand Ramuz, Souvenirs sur Igor Strawinsky, Lausanne, Editions de l'Aire, 1978 [1929].

A Bulletin on Iowa Open Meetings and Public Records Laws By Attorney General Tom Miller

L'évaluation des difficultés et des besoins des patients psychiatriques. Les échelles lausannoises ELADEB.

Il existe de multiples instruments d'évaluation du fonctionnement social, de la qualité de vie ou des besoins des patients psychiatriques qui peuvent aider dans l'élaboration des stratégies de traitement. Néanmoins, nombre d'entre eux ne répondent pas toujours aux attentes des cliniciens ou des chercheurs. En réponse à ces limitations, nous avons élaboré une nouvelle échelle de mesure subjective des difficultés et du besoin d'aide, intitulée ELADEB. Sur la base d'une activité de tri de cartes, il est possible en quelques minutes de dresser le profil de difficultés des patients, et de mettre en évidence les domaines dans lesquels ils estiment avoir besoin d'une aide supplémentaire par rapport à celle qui existe peut-être déjà.

Nursing Activities Score (NAS) como instrumento para medir carga de trabalho de enfermagem em UTI adulto

Pesquisa de campo, prospectiva, quantitativa, descritiva-exploratória, realizada na UTI geral/adulto de um hospital privado do município de São Paulo. Objetivos: avaliar o NAS - Nursing Activities Score - como medida de carga de trabalho de enfermagem; sua aplicabilidade por turnos e sua correspondência com o quantitativo de enfermagem efetivo. Classificados 33 pacientes: idade média: 70,4 anos (+/-16,5), 66,7% do sexo masculino; permanência média na UTI: 17 dias (+/- 20,4); SAPSII: 41,7 (+/-17,9); risco de morte: (RM) 33,5% (+/- 26,8); 63,6% transferidos para Unidades de Cuidados Semi-Intensivos, 18,2% evoluíram a óbito. Obtiveram-se 396 medidas por turnos (134-manhã; 132-tarde; 130-noturno), média de 55,4 (+/-12,3) e 147 medidas de NAS de 24h, média de 69,6 (+/-18,2). O instrumento mostrou-se mais adequado à aplicação em 24 horas que por turnos, tendendo a refletir o número de profissionais efetivo, revelando-se interessante instrumento de classificação de pacientes e carga de trabalho de enfermagem em terapia intensiva.

An Examination of Iowa's School Liaison Program, 2001

In the early 1990’s the Chief Juvenile Court Officers (JCOs) and other key players desired to provide services, such as school support, family support, and community support to both juvenile court and at-risk youths within the school setting. With strong support from both Iowa’s Attorney General and Governor the Iowa State Legislature first appropriated funds for school liaisons in 1994. The liaison program is currently funded with 75 percent state dollars appropriated to the Department of Human Services and a minimum of 25 percent match from the local school districts. In some cases the schools do not actually match funds with “school money,” rather they may utilize community money from other sources, such as the local decategorization process. In 1994, the state legislature funded this effort at $400,000. Since that time the amount has grown to more than $3,000,000. In the early years there were just a handful of liaisons working in a few school districts, but by the beginning of the 2000-2001 school year there were 304 schools served by 147 liaisons. The cost per liaison, including salary and benefits, was estimated at approximately $34,324 including both the DHS and school contributions. It was a desire of the Chief JCOs to place the liaisons under the school districts and thus allow them to be independent of the juvenile court. Agreements were developed between the schools and juvenile court regarding employee status, funding, information sharing, and other such issues.

An easy and safe procedure for temporal artery biopsy.

BACKGROUND: Temporal arteritis is a very serious form of vasculitis. Early treatment is essential to avoid blindness. Surgical biopsy of the temporal artery is the gold standard for the diagnosis, but facial nerve injuries may occur. OBJECTIVE: To describe a simple and safe procedure for temporal artery biopsy. METHODS: Case report. RESULTS: A 62-year-old-woman with presumed temporal arteritis was referred. Precise localization of temporal arteries and its branches was obtained with color duplex ultrasonography. Arterial wall thickening (halo sign) was observed in the affected arterial segments. A frontal branch was precisely localized and infiltrated with 1% lidocaine. About 1 cm was removed for histopathologic examination. Thirty minutes was required to perform this outpatient procedure. The diagnosis of temporal arteritis was confirmed, and the patient was rapidly and successfully treated with prednisone. CONCLUSIONS: Color duplex ultrasonography allows precise localization of temporal arteries and its branches. This echocardiography-guided surgical procedure is easy and safe. Most dermatologic surgeons can perform it.

Cell-free reconstitution of vacuole membrane fragmentation reveals regulation of vacuole size and number by TORC1.

Size and copy number of organelles are influenced by an equilibrium of membrane fusion and fission. We studied this equilibrium on vacuoles-the lysosomes of yeast. Vacuole fusion can readily be reconstituted and quantified in vitro, but it had not been possible to study fission of the organelle in a similar way. Here we present a cell-free system that reconstitutes fragmentation of purified yeast vacuoles (lysosomes) into smaller vesicles. Fragmentation in vitro reproduces physiological aspects. It requires the dynamin-like GTPase Vps1p, V-ATPase pump activity, cytosolic proteins, and ATP and GTP hydrolysis. We used the in vitro system to show that the vacuole-associated TOR complex 1 (TORC1) stimulates vacuole fragmentation but not the opposing reaction of vacuole fusion. Under nutrient restriction, TORC1 is inactivated, and the continuing fusion activity then dominates the fusion/fission equilibrium, decreasing the copy number and increasing the volume of the vacuolar compartment. This result can explain why nutrient restriction not only induces autophagy and a massive buildup of vacuolar/lysosomal hydrolases, but also leads to a concomitant increase in volume of the vacuolar compartment by coalescence of the organelles into a single large compartment.

Obesidade como fator de risco para a hipertensão entre profissionais de enfermagem de uma instituição filantrópica

Analisou-se a presença de obesidade relacionada com níveis de pressão alterados entre os profissionais de enfermagem de uma instituição filantrópica, tendo em vista a detecção precoce de possíveis hipertensos. A população constituiu-se de 147 profissionais de enfermagem com idade de 20-70 anos. Realizou-se entrevista estruturada, individual, pelo pesquisador no local de trabalho desses profissionais. 91,8% eram mulheres; 29,2% possuíam idade superior a 40 anos; 11,6% apresentaram PAS>140mmHg e 6,8% PAD>90mmHg; 12,2% apresentaram obesidade grau I-II; 38,1% das mulheres, RCQ>0,85, 12,2% com idade 40-49 anos; 2,1% dos homens apresentaram RCQ>1,0, 1,4% encontravam-se na faixa etária 40-49 anos. É possível identificar que, embora os profissionais de enfermagem conheçam a gravidade da doença e a importância da mudança nos hábitos de vida, ainda apresentam dificuldade para tal comportamento, o que sugere a necessidade de implementação de programas educativos no local de trabalho, de modo a contribuir e favorecer a mudança de comportamento destes profissionais.

Pédiatrie [Current progress in pediatrics: obesity and diagnosis approach to the febrile child]

The literature shows that obesity is a public health problem concerning especially the general paediatrician. While prevention has probably more chances of success than treatment, drugs or, in case of failure, the surgical approach are reserved for extreme cases. In the domain of infectiology the different laboratory tests allow only partially to diagnose severe infections. But in the context of a potential influenza pandemic rapid virologic tests become more and more important. They allow a more precise diagnosis and a reduction of hospitalisations and of antibiotic prescriptions. A review of the north American experience with the pneumococal vaccine shows that the heptavalent vaccine will change our approach in infants with fever in whom we suspect a severe infection.

Gender differences in paediatric patients of the swiss inflammatory bowel disease cohort study.

PURPOSE: Gender differences in paediatric patients with inflammatory bowel disease (IBD) are frequently reported as a secondary outcome and the results are divergent. To assess gender differences by analysing data collected within the Swiss IBD cohort study database since 2008, related to children with IBD, using the Montreal classification for a systematic approach. METHODS: Data on gender, age, anthropometrics, disease location at diagnosis, disease behaviour, and therapy of 196 patients, 105 with Crohn's disease (CD) and 91 with ulcerative or indeterminate colitis (UC/IC) were retrieved and analysed. RESULTS: THE CRUDE GENDER RATIO (MALE : female) of patients with CD diagnosed at <10 years of age was 2.57, the adjusted ratio was 2.42, and in patients with UC/IC it was 0.68 and 0.64 respectively. The non-adjusted gender ratio of patients diagnosed at ≥10 years was 1.58 for CD and 0.88 for UC/IC. Boys with UC/IC diagnosed <10 years of age had a longer diagnostic delay, and in girls diagnosed with UC/IC >10 years a more important use of azathioprine was observed. No other gender difference was found after analysis of age, disease location and behaviour at diagnosis, duration of disease, familial occurrence of IBD, prevalence of extra-intestinal manifestations, complications, and requirement for surgery. CONCLUSION: CD in children <10 years affects predominantly boys with a sex ratio of 2.57; the impact of sex-hormones on the development of CD in pre-pubertal male patients should be investigated.

Transcriptional regulation of MDR1, a gene involved in antifungal drug resistance in Candida albicans

ABSTRACT Upregulation of the Major Facilitator transporter gene MDR1 (Multi_drug Resistance 1) is one of the mechanisms observed in Candida albicans clinical isolates developing resistance to azole antifungal agents. To better understand this phenomenon, the cis-acting regulatory elements present in a modulatable reporter system under the control of the MDR1 promoter were characterized. In an azole-susceptible strain, transcription of this reporter is transiently upregulated in response to either benomyl or H2O2, whereas its expression is constitutively high in an azole-resistant strain (FR2). Two cis-acting regulatory elements, that are necessary and sufficient to convey the same transcriptional responses to a heterologous promoter (CDR2), were identified within the MDR1promoter. The first element, called BRE (for Benomyl Response Element, -296 to -260 with respect to the ATG start codon), is required for benomyl-dependent MDR1 upregulation and for constitutive high expression of MDR1 in FR2. The second element, termed HRE (for H2O2 Response Element, -561 to -520), is required for H2O2-dependent MDR1 upregulation, but is dispensable for constitutive high expression. Two potential binding sites (TTAG/CTAA) for the blip transcription factor Cap1p lie within the HRE. Moreover, inactivation of CAP1 abolished the transient response to H2O2 and diminished significantly the transient response to benomyl. Cap1p, which has been previously implicated in cellular responses to oxidative stress, may thus play a transacting and positive regulatory role in benomyl- and H2O2-dependent transcription of MDR1. However, it is not the only transcription factor involved in the response of MDR1 to benomyl. A minimal BRE element (-290 to -273) that is sufficient to detect in vitro sequence-specific binding of protein complexes in crude extracts prepared from C. albicans was also delimited. Genome-wide transcript profiling analyses undertaken with a matched pair of clinical isolates, one of which being azole-resistant and upregulating MDR1, and with an azole-susceptible strain exposed to benomyl, revealed that genes specifically upregulated by benomyl harbour in their promoters Cap1p binding site(s). This strengthened the idea that Cap1p plays a role in benomyl-dependent upregulation of MDR1. BRE-like sequences were also identified in several genes co-regulated with MDR1 in both conditions, which was consistent with the involvement of the BRE in both processes. A set of 147 mutants lacking a single transcription factor gene was next screened for loss of MDR1response to benomyl. Unfortunately, none of the tested mutants showed a loss of benomyl-dependent MDR1 upregulation. Nevertheless, a significant diminution of the response was observed in the mutants in which the MADS-box transcription factor Mcm1p and the C2H2 zinc finger transcription factor orf19.13374p were inactivated, suggesting that Mcm1p and orf19.13374p are involved in MDR1response to benomyl. Interestingly, the BRE contains a perfect match to the binding consensus of Mcm1p, raising the possibility that MDR1may be a direct target of this transcriptional activator. In conclusion, while the identity of the trans-acting factors that bind to the BRE and HRE remains to be confirmed, the tools we have developed during characterization of the cis-acting elements of the MDR1promoter should now serve to elucidate the nature of the components that modulate its activity. RESUME La surexpression du gène MDR1 (pour Résistance Multidrogue 1), qui code pour un transporteur de la famille des Major Facilitators, est l'un des mécanismes observés dans les isolats cliniques de la levure Candida albicans développant une résistance aux agents antifongiques appelés azoles. Pour mieux comprendre ce phénomène, les éléments de régulation agissant en cis dans un système rapporteur modulable sous le contrôle du promoteur MDR1 ont été caractérisés. Dans une souche sensible aux azoles, la transcription de ce rapporteur est transitoirement surélevée en réponse soit au bénomyl soit à l'agent oxydant H2O2, alors que son expression est constitutivement élevée dans une souche résistante aux azoles (souche FR2). Deux éléments de régulation agissant en cis, nécessaires et suffisants pour transmettre les mêmes réponses transcriptionnelles à un promoteur hétérologue (CDR2), ont été identifiés dans le promoteur MDR1. Le premier élément, appelé BRE (pour Elément de Réponse au Bénomyl, de -296 à -260 par rapport au codon d'initiation ATG) est requis pour la surexpression de MDR1dépendante du bénomyl et pour l'expression constitutive de MDR1 dans FR2. Le deuxième élément, appelé HRE (pour Elément de Réponse à l'H2O2, de -561 à -520), est requis pour la surexpression de MDR1 dépendante de l'H2O2, mais n'est pas impliqué dans l'expression constitutive du gène MDR1. Deux sites de fixation potentiels (TTAG/CTAA) pour le facteur de transcription Cap1p ont été identifiés dans l'élément HRE. De plus, l'inactivation de CAP1 abolit la réponse transitoire à l'H2O2 et diminua significativement la réponse transitoire au bénomyl. Cap1p, qui est impliqué dans les réponses de la cellule au stress oxydatif, doit donc jouer un rôle positif en trans dans la surexpression de MDR1 dépendante du bénomyl et de l'H2O2. Cependant, ce n'est pas le seul facteur de transcription impliqué dans la réponse au bénomyl. Un élément BRE d'une longueur minimale (de -290 à -273) a également été défini et est suffisant pour détecter une interaction spécifique in vitro avec des protéines provenant d'extraits bruts de C. albicans. L'analyse du profil de transcription d'une paire d'isolats cliniques comprenant une souche résistante aux azoles surexprimant MDR1, et d'une souche sensible aux azoles exposée au bénomyl, a révélé que les gènes spécifiquement surexprimés par le bénomyl contiennent dans leurs promoteurs un ou plusieurs sites de fixation pour Cap1p. Ceci renforce l'idée que Cap1p joue un rôle dans la surexpression de MDR1dépendante du bénomyl. Une ou deux séquences ressemblant à l'élément BRE ont également été identifiées dans la plupart des gènes corégulés avec MDR1 dans ces deux conditions, ce qui était attendu compte-tenu du rôle joué par cet élément dans les deux processus. Une collection de 147 mutants dans lesquels un seul facteur de transcription est inactivé a été testée pour la perte de réponse au bénomyl de MDR1. Malheureusement, la surexpression de MDR1 dépendante du bénomyl n'a été perdue dans aucun des mutants testés. Néanmoins, une diminution significative de la réponse a été observée chez des mutants dans lesquels le facteur de transcription à MADS-box Mcm1p et le facteur de transcription à doigts de zinc de type C2H2 orf19.13374p ont été inactivés, suggérant que Mcm1p et orf19.13374p sont impliqués dans la réponse de MDR1au bénomyl. Il est intéressant de noter que la BRE contient une séquence qui s'aligne parfaitement avec la séquence consensus du site de fixation de Mcm1p, ce qui soulève la possibilité que MDR1 pourrait être une cible directe de cet activateur transcriptionnel. En conclusion, alors que l'identité des facteurs agissant en trans en se fixant à la BRE et à la HRE reste à être confirmée, les outils que nous avons développés au cours de la caractérisation des éléments agissant en cis sur le promoteur MDR1 peut maintenant servir à élucider la nature des composants modulant son activité.

Social and medical vulnerability factors of emergency department frequent users in a universal health insurance system.

OBJECTIVES: The objectives were to identify the social and medical factors associated with emergency department (ED) frequent use and to determine if frequent users were more likely to have a combination of these factors in a universal health insurance system. METHODS: This was a retrospective chart review case-control study comparing randomized samples of frequent users and nonfrequent users at the Lausanne University Hospital, Switzerland. The authors defined frequent users as patients with four or more ED visits within the previous 12 months. Adult patients who visited the ED between April 2008 and March 2009 (study period) were included, and patients leaving the ED without medical discharge were excluded. For each patient, the first ED electronic record within the study period was considered for data extraction. Along with basic demographics, variables of interest included social (employment or housing status) and medical (ED primary diagnosis) characteristics. Significant social and medical factors were used to construct a logistic regression model, to determine factors associated with frequent ED use. In addition, comparison of the combination of social and medical factors was examined. RESULTS: A total of 359 of 1,591 frequent and 360 of 34,263 nonfrequent users were selected. Frequent users accounted for less than a 20th of all ED patients (4.4%), but for 12.1% of all visits (5,813 of 48,117), with a maximum of 73 ED visits. No difference in terms of age or sex occurred, but more frequent users had a nationality other than Swiss or European (n = 117 [32.6%] vs. n = 83 [23.1%], p = 0.003). Adjusted multivariate analysis showed that social and specific medical vulnerability factors most increased the risk of frequent ED use: being under guardianship (adjusted odds ratio [OR] = 15.8; 95% confidence interval [CI] = 1.7 to 147.3), living closer to the ED (adjusted OR = 4.6; 95% CI = 2.8 to 7.6), being uninsured (adjusted OR = 2.5; 95% CI = 1.1 to 5.8), being unemployed or dependent on government welfare (adjusted OR = 2.1; 95% CI = 1.3 to 3.4), the number of psychiatric hospitalizations (adjusted OR = 4.6; 95% CI = 1.5 to 14.1), and the use of five or more clinical departments over 12 months (adjusted OR = 4.5; 95% CI = 2.5 to 8.1). Having two of four social factors increased the odds of frequent ED use (adjusted = OR 5.4; 95% CI = 2.9 to 9.9), and similar results were found for medical factors (adjusted OR = 7.9; 95% CI = 4.6 to 13.4). A combination of social and medical factors was markedly associated with ED frequent use, as frequent users were 10 times more likely to have three of them (on a total of eight factors; 95% CI = 5.1 to 19.6). CONCLUSIONS: Frequent users accounted for a moderate proportion of visits at the Lausanne ED. Social and medical vulnerability factors were associated with frequent ED use. In addition, frequent users were more likely to have both social and medical vulnerabilities than were other patients. Case management strategies might address the vulnerability factors of frequent users to prevent inequities in health care and related costs.

Functional chromatin features are associated with structural mutations in cancer.

BACKGROUND: Structural mutations (SMs) play a major role in cancer development. In some cancers, such as breast and ovarian, DNA double-strand breaks (DSBs) occur more frequently in transcribed regions, while in other cancer types such as prostate, there is a consistent depletion of breakpoints in transcribed regions. Despite such regularity, little is understood about the mechanisms driving these effects. A few works have suggested that protein binding may be relevant, e.g. in studies of androgen receptor binding and active chromatin in specific cell types. We hypothesized that this behavior might be general, i.e. that correlation between protein-DNA binding (and open chromatin) and breakpoint locations is common across divergent cancers. RESULTS: We investigated this hypothesis by comprehensively analyzing the relationship among 457 ENCODE protein binding ChIP-seq experiments, 125 DnaseI and 24 FAIRE experiments, and 14,600 SMs from 8 diverse cancer datasets covering 147 samples. In most cancers, including breast and ovarian, we found enrichment of protein binding and open chromatin in the vicinity of SM breakpoints at distances up to 200 kb. Furthermore, for all cancer types we observed an enhanced enrichment in regions distant from genes when compared to regions proximal to genes, suggesting that the SM-induction mechanism is independent from the bias of DSBs to occur near transcribed regions. We also observed a stronger effect for sites with more than one protein bound. CONCLUSIONS: Protein binding and open chromatin state are associated with nearby SM breakpoints in many cancer datasets. These observations suggest a consistent mechanism underlying SM locations across different cancers.

Vivências de amamentação da criança portuguesa em idade escolar

Estudo descritivo e transversal, utilizando um questionário, com 1.078 crianças entre 7 e 12 anos de idade, dos terceiros e quartos anos do primeiro ciclo do ensino básico, de escolas públicas, para estudar as vivências de amamentação. A maioria delas, 918 (85,2%), sabia que tinha sido amamentada e 895 (83,0%) usaram chupeta. Um pequeno número viu a mãe amamentar e presenciou o pai junto da mãe quando amamentava ou respondeu que na escola os enfermeiros passaram algum conteúdo sobre amamentação. Além disso, a maioria das meninas não brincava de amamentar suas bonecas e 771 (71,5%) crianças disseram que esses brinquedos tinham mamadeira, e outras, chupetas, sendo que nas brincadeiras fingiam alimentar as bonecas com a mamadeira. Elas dizem que gostariam de amamentar, mas que teriam vergonha de fazê-lo em público. Os livros e desenhos animados com que estas crianças têm contato não apresentam figuras de mulheres amamentando. Grande número das crianças considera o leite materno como o melhor alimento para o bebê, mas verificou-se a presença de falsos conceitos e que nem todos sabiam o que era amamentar.
