Quand les diplômés de doctorat français partis à l'étranger auto évaluent leurs compétences
2016
Article paru en décembre 2018; International audience; La France se caractérise par un taux de chômage des jeunes docteurs élevé dans les premières années après la thèse, ce qui peut conduire certains d'entre eux à s'expatrier. Ce travail s'interroge sur la manière dont les jeunes docteurs partis à l'étranger perçoivent les compétences acquises dans leur formation doctorale, lorsqu'ils se comparent à leurs collègues de travail. A partir d'une enquête statistique et des éclairages plus qualitatifs, les résultats indiquent qu'ils valorisent globalement les compétences acquises durant leur doctorat même s'ils jugent que certaines d'entre elles comme les compétences relationnelles ou la gestion…

Plasmonic Stripes in Aqueous Environment Co-Integrated With Si3N4 Photonics
2018
We demonstrate the design, fabrication, and the experimental characterization of gold-based plasmonic stripes butt-coupled with low-pressure-chemical-vapor-deposition (LPCVD)-based Si3N4 waveguides for the excitation of surface-plasmon-polariton (SPP) modes in aqueous environment. Plasmonic gold stripes, in aqueous environment, with cross-sectional dimensions of 100 nm × 7 μm were interfaced with 360 nm × 800 nm Si3N4 waveguides cladded with low-temperature-oxide, exploiting linear photonic tapers with appropriate vertical (VO) and longitudinal (LO) offsets between the plasmonic and photonic waveguide facets. An interface insertion loss of 2.3 ± 0.3 dB and a plas…
Incidence of peripheral intravenous catheter failure and complications in paediatric patients: Systematic review and meta analysis.
2020
Background: Most paediatric patients have at least one peripheral intravenous catheter insertion during their hospitalisation. Despite the important function of peripheral intravenous catheters for delivery of intravenous therapy, failure and complications rates are widely reported; however these results have not been synthesised. Objective: To provide an overall estimate of peripheral intravenous catheter failure and related complications in the paediatric population. Design: Systematic review and meta-analysis Data sources: The electronic databases, Cochrane Central Register of Controlled Trials, US National Library of Medicine National Institutes of Health, Cumulative Index of Nursing an…
The subway tunneling technique for distal shunt catheter insertion.
2019
Dear Editor,We read with interest the article by Osman et al. titled ‘Trocar assisted distal shunt tube insertion with intra-operative X-Ray confirmation’. The authors purpose their technique to pl...
Technical and surgical aspects of the sphenopalatine ganglion (SPG) microstimulator insertion procedure
2015
Cluster headache (CH) is a debilitating, severe form of headache. A novel non-systemic therapy has been developed that produces therapeutic electrical stimulation to the sphenopalatine ganglion (SPG). A transoral surgical technique for inserting the Pulsante SPG Microstimulator into the pterygopalatine fossa (PPF) is presented herein. Technical aspects include detailed descriptions of the preoperative planning using computed tomography or cone beam computed tomography scans for presurgical digital microstimulator insertion into the patient specific anatomy and intraoperative verification of microstimulator placement. Surgical aspects include techniques to insert the microstimulator into the…
Needle Insertion Difficulty Algorithm (NIDA): A novel pilot study to predict Huber needle insertion difficulty in totally implanted devices.
2021
Safeguarding of venous assets in cancer patients provides for positioning vascular devices. In totally implanted central venous access devices, hereinafter referred as TIVADs, it’s necessary introducing Huber needle, into subcutaneous port, to use it. This procedure is not easy for all implanted devices. The procedural difficulty is to be attributed both to the type of the implanted port and to the skill of the clinician. The degree of patient satisfaction is variable and related with the clinician performing the maneuver. It follows a professional dissatisfaction of the clinician and a hesitation of the patient. Moreover, the incorrect positioning of the Huber needle into the port, could …
The Orogastric Tube Guide® as a novel strategy for gastric tube insertion: a prospective, randomized controlled clinical trial
2020
BACKGROUND Gastric tube insertion, either orally or nasally, is daily practice in anesthesia and intensive care. "Blind" insertion represents the common conventional method and is associated with low first-pass success and frequent complications. This trial aimed to evaluate the novel gastric tube guide as a rigid conduit in regard to insertion success rate, time required and associated complications versus the conventional "blind" insertion method. We hypothesized that the insertion success rate is higher using the Orogastric tube guide. METHODS This trial was approved by ethics committee prior to patient recruitment. In a randomized order, anesthetists performed oral insertion of a gastri…
Vibrio vulnificus: from water to host
2017
Vibrio vulnificus is an aquatic pathogen autochthonous from temperate, tropical and subtropical ecosystems where it lives either as a sessile cell, forming biofilms or as a free-swimming cell. From these locations, the pathogen can occasionally infect humans and fish causing a disease named vibriosis. The most severe form of human and fish vibriosis is associated with the pathogen’s ability to spread from the infection site to the bloodstream and multiply, process known as invasion. Before invasion, the pathogen has to colonize the mucosal host surface, process that involves not only bacterial attachment/adhesion but also resistance to mucosal immunity, commensal microbiota (competitors) an…
Single-mode Bragg gratings in tapered few-modes and multimode fibers
2019
We propose the implementation of fiber Bragg gratings in tapered few-mode and multimode fibers to accomplish single-mode operation by reducing the core diameter, while preserving the core-cladding structure. The gratings present a single reflection band, and the device shows low insertion losses after the taper fabrication and the fiber Bragg gratings inscription. The excitation of high-order odd modes in the core of the fiber has been identified as the main loss mechanism; it can be prevented by means of symmetric illumination of the fibers. We also demonstrate the excitation of high-order cladding modes (cladding-air modes) along the taper transitions; these modes can be removed without a…
