Densidade de Neoseiulus californicus (McGregor, 1954) (Acari: Phytoseiidae) no controle do ácaro-vermelho da macieira, Fraiburgo-SC

O controle biológico aplicado de Panonychus ulmi (Koch) (Acari: Tetranychidae) em macieira iniciou em Vacaria (RS), em 1992, com a multiplicação de Neoseiulus californicus em estufas e liberação nas áreas de ocorrência da praga, fazendo com que o equilíbrio entre ambos os ácaros ocorresse semanas após a liberação. O presente trabalho teve o objetivo de verificar o efeito da densidade de N. californicus a ser liberada em pomar de macieira, Malus domestica (Borkh.) Mansf., para o controle do ácaro-vermelho. Foi selecionado um pomar comercial em Fraiburgo (SC) e liberados os fitoseídeos nas densidades de 50.000, 100.000 e 150.000 por ha, originados da criação comercial situada na Renar Maçãs (Fraiburgo). O controle do ácaro foi medido através da injúria, devido à alimentação de P. ulmi, e avaliado por meio de uma escala de sintomas de bronzeamento, e do monitoramento de ovos hibernantes em maio, julho e setembro. O tratamento com 150.000 fitoseídeos reduziu a população de ácaros- vermelhos após 16 dias da liberação, enquanto os demais tratamentos necessitaram de 21 dias. A injúria das folhas foi menor no tratamento com 150.000. Os ovos hibernantes em maio, nas parcelas de 50.000 e 100.000, foram, respectivamente, 75% e 69% maiores do que na parcela com 150.000 fitoseídeos. Concluiu-se que a liberação de 150.000 N. californicus foi mais eficiente no controle de P. ulmi no estágio fenológico reprodutivo da macieira.

Chemotherapy and radiotherapy in nasopharyngeal carcinoma: an update of the MAC-NPC meta-analysis.

BACKGROUND: A previous individual patient data meta-analysis by the Meta-Analysis of Chemotherapy in Nasopharynx Carcinoma (MAC-NPC) collaborative group to assess the addition of chemotherapy to radiotherapy showed that it improves overall survival in nasopharyngeal carcinoma. This benefit was restricted to patients receiving concomitant chemotherapy and radiotherapy. The aim of this study was to update the meta-analysis, include recent trials, and to analyse separately the benefit of concomitant plus adjuvant chemotherapy. METHODS: We searched PubMed, Web of Science, Cochrane Controlled Trials meta-register, ClinicalTrials.gov, and meeting proceedings to identify published or unpublished randomised trials assessing radiotherapy with or without chemotherapy in patients with non-metastatic nasopharyngeal carcinoma and obtained updated data for previously analysed studies. The primary endpoint of interest was overall survival. All trial results were combined and analysed using a fixed-effects model. The statistical analysis plan was pre-specified in a protocol. All data were analysed on an intention-to-treat basis. FINDINGS: We analysed data from 19 trials and 4806 patients. Median follow-up was 7·7 years (IQR 6·2-11·9). We found that the addition of chemotherapy to radiotherapy significantly improved overall survival (hazard ratio [HR] 0·79, 95% CI 0·73-0·86, p<0·0001; absolute benefit at 5 years 6·3%, 95% CI 3·5-9·1). The interaction between treatment effect (benefit of chemotherapy) on overall survival and the timing of chemotherapy was significant (p=0·01) in favour of concomitant plus adjuvant chemotherapy (HR 0·65, 0·56-0·76) and concomitant without adjuvant chemotherapy (0·80, 0·70-0·93) but not adjuvant chemotherapy alone (0·87, 0·68-1·12) or induction chemotherapy alone (0·96, 0·80-1·16). The benefit of the addition of chemotherapy was consistent for all endpoints analysed (all p<0·0001): progression-free survival (HR 0·75, 95% CI 0·69-0·81), locoregional control (0·73, 0·64-0·83), distant control (0·67, 0·59-0·75), and cancer mortality (0·76, 0·69-0·84). INTERPRETATION: Our results confirm that the addition of concomitant chemotherapy to radiotherapy significantly improves survival in patients with locoregionally advanced nasopharyngeal carcinoma. To our knowledge, this is the first analysis that examines the effect of concomitant chemotherapy with and without adjuvant chemotherapy as distinct groups. Further studies on the specific benefits of adjuvant chemotherapy after concomitant chemoradiotherapy are needed.

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.

CTCPS-MAC - Batería Para el Estudio de las Condiciones de Trabajo de Carácter Psicosocial

El estudio de las condiciones de trabajo de carácter psicosocial CTCPS-MAC consta de 75 ítems que agrupan cuatro dimensiones, que se pueden evaluar por separado y un total de 14 factores. Tiene como intención la evaluación de la percepción que tiene la población trabajadora de las condiciones de trabajo de carácter psicosocial en su propio entorno laboral así como de los factores individuales y los síntomas subjetivos y alteraciones de la salud.
