Profil clinico-biologique des patients atteints d'un syndrome de Cushing paranéoplasique dans le cadre d'un carcinome pulmonaire à petites cellules
No full textNous avons étudié 783 dossiers des patients atteints de carcinome pulmonaire à petites cellules (CPC), dont 25 (3.19 %) avec un syndrome de Cushing paranéoplasique (SCP). La médiane de survie du groupe SCP est de 4.7 mois. Le SCP se voit surtout dans les formes étendues du CPC, est accompagné d un status de performance altéré. Il est important de traiter le SCP avant l administration du traitement anticancéreux pour essayer de limiter les risques infectieux liés au SCP. La médiane de survie de ce sous-groupe est de 2.9 mois. Une cortisolémie élevée est un facteur de mauvais pronostique au sein de la cohorte SCP. Le SCP influence la survie par le biais de complications infectieuses et métaboliques, il existe une tendance à la chimiosensibilité moins importante de CPC accompagné d un SCP. Il existe une différence statistiquement significative de la survie en fonction de la présentation clinique ou biologique du SCP. Cette différence semble être liée à la vitesse de l imprégnation cortisolique plutôt qu un taux de cortisolémie au disgnostic. La vitesse d'imprégnation et donc de l apparition des complications métaboliques et infectieuses du SCP est plus rapide dans le sous-groupe du SCP à présentation biologique. Le syndrome de Cushing paranéoplasique lorsqu il est présent dans un cadre de carcinome neuroendocrine à petites cellules pulmonaire est un facteur indépendant de mauvais pronostique, au même titre que les facteurs déjà connus comme le sexe masculin, PS altéré, âge avancé, forme étendue du CPC ou une maladie réfractaire au traitement antinéoplasique.GRENOBLE1-BU Médecine pharm.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
First- and second-line therapy for advanced nonsmall cell lung cancer.
No full textThe objectives for the treatment of advanced nonsmall cell lung cancer are palliative and include improvement of survival, symptom control, quality of life and cost. The level of evidence of these benefits is based on multiple randomised trials and meta-analyses. Cisplatin-based chemotherapy with one of the regimens shown to be effective should be preferred. Carboplatin may be substituted for cisplatin if medical contraindications exist. Nonplatinum-based regimens are indicated as first-line treatment for advanced nonsmall cell lung cancer in patients for whom platinum-based chemotherapy is contraindicated. Single drug chemotherapy may be considered in patients with poor performance status. The choice of the active drugs depends on the patient's medical condition. There is no conclusive evidence that high doses of cisplatin (100-120 mg.m(-2)) provide better results than standard lower doses (50-60 mg.m(-2)) in terms of survival. The optimal duration of chemotherapy is poorly documented in advanced nonsmall cell lung cancer. A minimum of four to six cycles is advised in responding patients. Second-line chemotherapy is now accepted as a standard and should be offered to patients with good performance status and failing platinum-based first-line chemotherapy. Evidence is in favour of docetaxel and in the case of adenocarcinoma and adequate renal function, pemetrexed is recommended.Journal ArticleReviewSCOPUS: re.jinfo:eu-repo/semantics/publishe
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
