PROCEEDINGS OF THE LLL YOUNG RESEARCHERS CONFERENCE 1

International audienceThis publication gathers papers of the young linguistics researchers international conference which took place at the University François-Rabelais de Tours on the 26th and 27th of May 2014. These two days were organized by PhD students from the Laboratoire Ligérien de Linguistique (UMR 7270 CNRS - BNF) and were focused on the articulation between data and theory.Ce recueil réunit les actes des journées d’étude internationales des jeunes chercheurs en linguistique s’étant tenues à l’Université François Rabelais de Tours les 26 et 27 mars 2014.

Interface Dipole : Effects on Threshold Voltage and Mobility for both Amorphous and Poly-crystalline Organic Field Effect Transistors

We report a detailed comparison on the role of a self-assembled monolayer (SAM) of dipolar molecules on the threshold voltage and charge carrier mobility of organic field-effect transistor (OFET) made of both amorphous and polycrystalline organic semiconductors. We show that the same relationship between the threshold voltage and the dipole-induced charges in the SAM holds when both types of devices are fabricated on strictly identical base substrates. Charge carrier mobilities, almost constant for amorphous OFET, are not affected by the dipole in the SAMs, while for polycrystalline OFET (pentacene) the large variation of charge carrier mobilities is related to change in the organic film structure (mostly grain size).Comment: Full paper and supporting informatio

Conscious surgery: influence of the environment on patient anxiety

Aims: i) To investigate anxiety arising from the experience of the clinical environment during surgery under local/ regional anaesthesia and, ii) to uncover the specific aspects patients find anxiety provoking and possibly dissuade them from opting for such anaesthesia. Background: Operating theatres have historical been designed for safe, efficient surgery on the unconscious patient and not primarily designed for the care of the ‘awake’ patient. However, with the rise in day surgery, the quantity of surgery performed under local/ regional anaesthesia is increasing. Method: As part of a larger study investigating anxiety within modern elective day surgery, adult patients undergoing surgery and local/ regional anaesthesia (n=214) were provided with a questionnaire on the day of surgery for return by mail 24 - 48 hours following surgery. Findings: The experience of being awake, possibly feeling surgeon, seeing body cut open or surgery being more painful were anxiety provoking aspects. Utilising factor analysis ‘intra-operative apprehension’, ‘anaesthetic information provision and ‘health control’ were identified as central features. Moreover, when employing multiple regression, apprehension associated with the intra-operative experience and anaesthetic information provision were significantly associated with an increase in the overall level of anxiety. Conclusions: Although the surrounding clinical environment has previously been a cause of apprehension, the sensations associated with the physical act of surgery on the conscious self appear also to have a considerable influence. Focusing care upon managing patient intra-operative experience and providing anaesthetic information in advance may help limit anxiety and expel the apparent misapprehensions associated with conscious surgery

Reproducibility of blood tests of liver fibrosis in clinical practice

Objectives:To evaluate the inter-laboratory reproducibility of blood test for liver fibrosis: FibroMeter, Fibrotest, APRI and their composites variables. Design and methods: Four studies, including 147 patients, were performed: study #1 included 2 metachronous blood samples and 2 laboratories; studies #2, #3 and #4 included synchronous samples with assays delayed at day 1 in 12 laboratories, at day 0 in 10 laboratories and at day 0 or 1 in 2 laboratories, respectively. Agreement was evaluated by the intraclass correlation coefficient (ric). Results: In studies #1, #2 and #4, ric for FibroMeter was 0.893, 0.942 and 0.991, respectively. In study #3, the ric were: FibroMeter: 0.963, Fibrotest: 0.984, APRI: 0.949. Large simulated variations in composite variables had a weak impact on FibroMeter. Conclusions: When blood marker limits are controlled, inter-laboratory agreement of blood tests is excellent in clinical practice conditions. Blood tests are robust against the variability of composite blood variables

Estimation of Nuwiq® (simoctocog alfa) activity using one-stage and chromogenic assays-Results from an international comparative field study.

BACKGROUND Accurate determination of coagulation factor VIII activity (FVIII:C) is essential for effective and safe FVIII replacement therapy. FVIII C can be measured by one-stage and chromogenic substrate assays (OSAs and CSAs, respectively); however, there is significant interlaboratory and interassay variability. AIMS This international comparative field study characterized the behaviour of OSAs and CSAs used in routine laboratory practice to measure the activity of Nuwiq® (human-cl rhFVIII, simoctocog alfa), a fourth-generation recombinant human FVIII produced in a human cell line. METHODS FVIII-deficient plasma was spiked with Nuwiq® or Advate® at 1, 5, 30 and 100 international units (IU)/dL. Participating laboratories analysed the samples using their routine procedures and equipment. Accuracy, inter- and intralaboratory variation, CSA:OSA ratio and the impact of different OSA and CSA reagents were assessed. RESULTS Forty-nine laboratories from 9 countries provided results. Mean absolute FVIII:C was comparable for both products at all concentrations with both OSA and CSA, with interproduct ratios (Nuwiq® :Advate® ) of 1.02-1.13. Mean recoveries ranged from 97% to 191% for Nuwiq® , and from 93% to 172% for Advate® , with higher recoveries at lower concentrations. Subgroup analyses by OSA and CSA reagents showed minor variations depending on reagents, but no marked differences between the two products. CSA:OSA ratios based on overall means ranged from 0.99 to 1.17 for Nuwiq® and from 1.01 to 1.17 for Advate® . CONCLUSIONS Both OSAs and CSAs are suitable for the measurement of FVIII:C of Nuwiq® in routine laboratory practice, without the need for a product-specific reference standard
