Intermittierende oder Persistierende Rhinitis bei Kindern und Jugendlichen mit Asthma: «The Swiss LARA paediatrics survey [Intermittent or persistent rhinitis in children and adolescents with Asthma: «the Swiss LARA paediatrics survey»].

Asthma and allergic rhinitis are chronic inflammatory airway diseases which often occur concomitantly. The objective of the LARA program was to identify the comorbidities and characteristics of asthma (A), intermittent or persistent rhinitis (IPR) and physician defined atopic dermatitis (AD) in 6- to 16-year old asthmatic Swiss children and adolescents. Overall, 126 general practitioners and paediatricians collected the data of 670 asthmatics. Approximately one third of the asthmatic children in Switzerland had well-controlled asthma. Almost two thirds of these asthmatics suffered from concomitant IPR. The latter presented with significantly less symptoms while the treatment rates with inhaled corticosteroids (approximately 90%) and leukotriene-receptorantagonists (approximately 50%) were comparable. However, there were almost twice as many passive smokers in the less well-controlled group. The prevalence of AD was similar in both groups. IPR and AD may play an important role as risk factors in the future development of asthma.

Allergic rhinitis in patients with asthma: the Swiss LARA (Link Allergic Rhinitis in Asthma) survey.

OBJECTIVE: To determine the characteristics of asthma (A) and allergic rhinitis (AR) among asthma patients in primary care practice. RESEARCH DESIGN AND METHODS: Primary care physicians, pulmonologists, and allergologists were asked to recruit consecutive asthma patients with or without allergic rhinitis from their daily practice. Cross-sectional data on symptoms, severity, treatment and impact on quality of life of A and AR were recorded and examined using descriptive statistics. Patients with and without AR were then compared. RESULTS: 1244 asthma patients were included by 211 physicians. Asthma was controlled in 19%, partially controlled in 27% and not controlled in 54%. Asthma treatment was generally based on inhaled corticosteroids (ICS) with or without long acting beta 2 agonists (78%). A leukotriene receptor antagonist (LTRA) was used by 46% of the patients. Overall, 950 (76%) asthma patients had AR (A + AR) and 294 (24%) did not (A - AR). Compared to patients with A - AR, A + AR patients were generally younger (mean age +/- standard deviation: 42 +/- 16 vs. 50 +/- 19 years, p < 0.001) and fewer used ICS (75% vs. 88%, p < 0.001). LTRA usage was similar in both groups (46% vs. 48%). Asthma was uncontrolled in 53% of A + AR and 57% of A - AR patients. Allergic rhinitis was treated with a mean of 1.9 specific AR medications: antihistamines (77%), nasal steroids (66%) and/or vasoconstrictors (38%), and/or LTRA (42%). Rhinorrhoea, nasal obstruction, or nasal itching were the most frequently reported AR symptoms and the greatest reported degree of impairment was in daily activities/sports (55%). CONCLUSIONS: Allergic rhinitis was more common among younger asthma patients, increased the burden of symptoms and the need for additional medication but was associated with improved asthma control. However, most asthma patients remained suboptimally controlled regardl-ess of concomitant AR.

Star et personnage dans la genèse filmique: Edwige Feuillère chez Autant-Lara (1954-1958)

A 47 ans, Edwige Feuillère est la vedette principale du Blé en herbe (1954), où elle incarne une femme d'âge mûr qui entreprend l'initiation amoureuse d'un jeune homme ; quatre ans plus tard, elle joue dans En cas de malheur le rôle d'une épouse qui, dans l'abnégation la plus complète, accepte les infidélités de son mari et s'efface devant le couple formé par Jean Gabin (54 ans) et Brigitte Bardot (24 ans). La place accordée aux deux personnages interprétés par Feuillère sera examinée en termes de construction de l'image d'une star vieillissante à travers l'étude du triangle amoureux qui structure le récit de ces deux adaptations (qu'il s'agira de comparer aux romans de Colette et de Simenon dont elles sont issues), de la stratégie promotionnelle pratiquée et des discours émis à propos de Feuillère au sein de la réception critique. Le contexte de production des films ainsi que certaines versions non retenues du scénario seront discutées à partir des archives du fonds Claude Autant-Lara de la Cinémathèque suisse.

Jean Aurenche, Pierre Bost et Claude Autant-Lara, auteurs de Douce: genèse d'une pratique scénaristique

A la lumière des archives du fonds Claude Autant-Lara déposé à la Cinémathèque suisse, cet article aborde la naissance d'une collaboration entre le réalisateur et le tandem de scénaristes Jean Aurenche et Pierre Bost, à travers la genèse scénaristique du film Douce (1942-1943). Les discours de réception désignent habituellement "Aurenchébost" comme s'il s'agissait d'un auteur unique avec une méthode de création. Il convient de reconsidérer leur travail dans l'historicité et la contingence des pratiques d'écriture. A ce titre, les documents scénaristiques procèdent à la fois d'une dimension processuelle - un texte en devenir - et une dimension interlocutive - le fruit d'une activité concertée. Cette dernière implique, entre autres, un jeu de formatage et de pagination dans la rédaction de la continuité dialogue et du découpage technique. Enfin, la scénarisation ne se limite pas à des tours d'écriture mais doit être également considérée en termes de rédactions conversationnelles.

Low doses of ionizing radiation promote tumor growth and metastasis by enhancing angiogenesis.

Radiotherapy is a widely used treatment option in cancer. However, recent evidence suggests that doses of ionizing radiation (IR) delivered inside the tumor target volume, during fractionated radiotherapy, can promote tumor invasion and metastasis. Furthermore, the tissues that surround the tumor area are also exposed to low doses of IR that are lower than those delivered inside the tumor mass, because external radiotherapy is delivered to the tumor through multiple radiation beams, in order to prevent damage of organs at risk. The biological effects of these low doses of IR on the healthy tissue surrounding the tumor area, and in particular on the vasculature remain largely to be determined. We found that doses of IR lower or equal to 0.8 Gy enhance endothelial cell migration without impinging on cell proliferation or survival. Moreover, we show that low-dose IR induces a rapid phosphorylation of several endothelial cell proteins, including the Vascular Endothelial Growth Factor (VEGF) Receptor-2 and induces VEGF production in hypoxia mimicking conditions. By activating the VEGF Receptor-2, low-dose IR enhances endothelial cell migration and prevents endothelial cell death promoted by an anti-angiogenic drug, bevacizumab. In addition, we observed that low-dose IR accelerates embryonic angiogenic sprouting during zebrafish development and promotes adult angiogenesis during zebrafish fin regeneration and in the murine Matrigel assay. Using murine experimental models of leukemia and orthotopic breast cancer, we show that low-dose IR promotes tumor growth and metastasis and that these effects were prevented by the administration of a VEGF receptor-tyrosine kinase inhibitor immediately before IR exposure. These findings demonstrate a new mechanism to the understanding of the potential pro-metastatic effect of IR and may provide a new rationale basis to the improvement of current radiotherapy protocols.

Protocol for the modeling the epidemiologic transition study: a longitudinal observational study of energy balance and change in body weight, diabetes and cardiovascular disease risk.

ABSTRACT: BACKGROUND: The prevalence of obesity has increased in societies of all socio-cultural backgrounds. To date, guidelines set forward to prevent obesity have universally emphasized optimal levels of physical activity. However there are few empirical data to support the assertion that low levels of energy expenditure in activity is a causal factor in the current obesity epidemic are very limited. METHODS: The Modeling the Epidemiologic Transition Study (METS) is a cohort study designed to assess the association between physical activity levels and relative weight, weight gain and diabetes and cardiovascular disease risk in five population-based samples at different stages of economic development. Twenty-five hundred young adults, ages 25-45, were enrolled in the study; 500 from sites in Ghana, South Africa, Seychelles, Jamaica and the United States. At baseline, physical activity levels were assessed using accelerometry and a questionnaire in all participants and by doubly labeled water in a subsample of 75 per site. We assessed dietary intake using two separate 24-h recalls, body composition using bioelectrical impedance analysis, and health history, social and economic indicators by questionnaire. Blood pressure was measured and blood samples collected for measurement of lipids, glucose, insulin and adipokines. Full examination including physical activity using accelerometry, anthropometric data and fasting glucose will take place at 12 and 24 months. The distribution of the main variables and the associations between physical activity, independent of energy intake, glucose metabolism and anthropometric measures will be assessed using cross-section and longitudinal analysis within and between sites. DISCUSSION: METS will provide insight on the relative contribution of physical activity and diet to excess weight, age-related weight gain and incident glucose impairment in five populations' samples of young adults at different stages of economic development. These data should be useful for the development of empirically-based public health policy aimed at the prevention of obesity and associated chronic diseases.

Mito, tragedia y metateatro en el teatro espanol del siglo XX : ensayo sobre el cuerpo y la conciencia en el drama

RÉSUMÉMythe, tragédie et méta-théâtre sont des termes techniques provenant de disciplines comme l'anthropologie, l'histoire, la théorie et la critique littéraires. Malgré le fait que l'on puisse les assigner à des périodes historiques déterminées, ce sont des notions qui ont encore un sens à la fois actuel (elles sont indispensables pour comprendre le théâtre contemporain) et concret (à travers les différentes poétiques qui les reconfigurent, elles affectent le spectateur d'une certaine façon, ont un effet déterminé sur son corps et sa conscience). Je propose donc de les définir synthétiquement en fonction de l'effet qu'ils produisent sur le spectateur qui est conçu comme une unité de corps et de conscience. Le corps étant défini comme le lieu des émotions, la conscience sera la connaissance que le sujet acquiert de soi et du monde en fonction de ces émotions. Or, le mûthos génère des émotions que la tragédie purge à travers le phénomène de la catharsis. En revanche, le méta-théâtre interrompt le processus émotif de la conscience. Tout en appuyant mes définitions sur des notions de psychologie, neurologie et physique quantique, j'oppose tragédie et méta-théâtre de la façon suivante: la tragédie produit une forme de conscience incarnée chez le spectateur, alors que le méta-théâtre n'aboutit qu'à une forme de conscience cartésienne ou vision désincarnée. J'applique ensuite cette conception à une série de pièces importantes de l'histoire du théâtre espagnol au XXe siècle qui comportent toutes une part de réécriture d'un ou de plusieurs mythes. Je constate une généralisation du traitement méta-théâtral de la réécriture, au détriment non du tragique, mais de la tragédie proprement dite. Par conséquent, je diagnostique un déficit d'incarnation dans le théâtre espagnol au XXe siècle.
