Identification des stratégies déployées par les infirmières pour offrir des soins palliatifs en fin de vie dans des unités de soins aigus

La réalité veut que beaucoup de personnes en fin de vie meurent dans des unités de soins aigus. Aussi, les infirmières qui travaillent dans ce milieu ont à prodiguer des soins infirmiers à une clientèle à la fois de soins aigus et de soins palliatifs. Par contre, celles-ci ont à faire face, entre autres, à des contraintes et obstacles organisationnels et environnementaux qui viennent compliquer la prestation de soins infirmiers palliatifs au travers d’une clientèle majoritairement de soins aigus. Il importe donc de savoir comment elles y parviennent. Cette étude exploratoire descriptive a pour but d’explorer et de décrire les stratégies que les infirmières de milieux de soins aigus déploient pour favoriser une pratique optimale de soins palliatifs de fin de vie. Le cadre de référence utilisé est le profil des compétences générales et spécifiques en soins palliatifs attribué aux infirmières du MSSS (2008). Huit participantes (infirmières) travaillant dans des unités de médecine et de cardiologie dans les établissements du CHU de Québec ont été rencontrées. Beaucoup de stratégies ont été identifiées, dont une plus propice à ce milieu soit, « Optimiser le temps passé auprès du patient et sa famille ». La stratégie « Faire de l’enseignement et donner aux proches de l’information » est celle qui revient le plus souvent dans le discours de ces infirmières. Également, on note des divergences quant aux obstacles et aux facteurs favorables mentionnés dans la littérature générale en soins palliatifs.

Time-resolved fluorescence observation of di-tyrosine formation in horseradish peroxidase upon ultrasound treatment leading to enzyme inactivation

The application of ultrasound to a solution can induce cavitional phenomena and generate high localised temperatures and pressures. These are dependent of the frequency used and have enabled ultrasound application in areas such as synthetic, green and food chemistry. High frequency (100 kHz to 1 MHz) in particular is promising in food chemistry as a means to inactivate enzymes, replacing the need to use periods of high temperature. A plant enzyme, horseradish peroxidase, was studied using time-resolved fluorescence techniques as a means to assess the effect of high frequency (378 kHz and 583 kHz) ultrasound treatment at equivalent acoustic powers. This uncovered the fluorescence emission from a newly formed species, attributed to the formation of di-tyrosine within the horseradish peroxidase structure caused by auto-oxidation, and linked to enzyme inactivation.

Dinoflagelados (Peridiniales, Prorocentrales) do microplâncton na plataforma continental e talude do extremo sul do Brasil (inverno 2005, verão 2007)

This study aimed at identifying morpho-species of microplankton dinoflagellates (> 20 μm) of the order Peridiniales and Prorocentrales off Santa Marta Grande Cape, CSMG (SC, 28º 40’ S) and Albardão-Chui, AC ( r S, 34º 40’ S) during oceanographic cruises conducted in winter 2005 and summer 2007. Plankton samples were obtained by vertical net (mesh size 20 μm) hauls preserved with formaldehyde 4% and analyzed using the inverted microscope equipped with a digital camera. The identification of Peridiniales species was based on the number and morphology of thecal plates enhanced with Calco Fluor White M r 2 whenever necessary and the identification of Prorocentrales was based on cell size, shape, presence of apical processes, pore pattern and marks at the intercalary band. We identified 25 species, including Protoperidinium (11), Prorocentrum (6), Corythodinium (3), Podolampas (2), Oxytoxum (2) and Heterocapsa (1). Prorocentrum species were widely distributed on the continental shelf of southern Brazil, while Peridiniales species were mainly found off Albardão-Chui during winter, especially under the influence of the plume of La Plata River. Oxytoxum milneri was the first time recorded in southern Brazil, while Protoperidinium cassum var. cassum , P. curtipes and Heterocapsa triquetra , were first registered in Brazil.

Facteurs influençant la prescription de la médication cardioprotectrice recommandée chez les patients avec une maladie artérielle périphérique

Introduction : Les guides de pratique recommandent que les patients avec une maladie artérielle périphérique (MAP) soient traités médicalement afin de réduire la survenue d’évènements cardiovasculaires majeurs. Objectif : Identifier les facteurs associés à la prescription des thérapies préventives recommandées. Méthode : Les patients avec une MAP (n=362) traités consécutivement par angiodilatation fémoropoplitée entre 2008 et 2010 dans un centre tertiaire (CHU de Québec, Canada) ont été inclus dans l’étude. L’issue clinique primaire était la prescription de trois thérapies combinées. Résultats : Au total, 52% des patients recevaient la thérapie combinée. La présence d’au moins trois facteurs de risque cardiovasculaire (Rapport de cotes (RC)=4,51; IC 95% : 2,76-7,37) était le facteur le plus fortement associé à la prise des thérapies combinées. Conclusion : La prise en charge du risque cardiovasculaire des patients avec une MAP est encore sous-optimale. Une meilleure compréhension des barrières et des facilitateurs à l’application des recommandations est toujours nécessaire.

Measurement of the doubly-polarized He3→(γ→,n)pp reaction at 16.5 MeV and its implications for the GDH sum rule

We report new measurements of the double-polarized photodisintegration of 3He at an incident photon energy of 16.5 MeV, carried out at the High Intensity γ-ray Source (HIγS) facility located at Triangle Universities Nuclear Laboratory (TUNL). The spin-dependent double-differential cross sections and the contribution from the three-body channel to the Gerasimov–Drell–Hearn (GDH) integrand were extracted and compared with the state-of-the-art three-body calculations. The calculations, which include the Coulomb interaction and are in good agreement with the results of previous measurements at 12.8 and 14.7 MeV, deviate from the new cross section results at 16.5 MeV. The GDH integrand was found to be about one standard deviation larger than the maximum value predicted by the theories.

Long Term Therapy with Lenalidomide in a patient with POEMS Syndrome

Lenalidomide is an effective therapy against malignant plasma cells and a potent agent against proinflammatory and proangiogenic cytokines. The use of lenalidomide in POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein with plasma cells, skin changes) has been reported, but its benefit in long-term use is not well established. A 55-year-old man with POEMS and debilitating polyneuropathy was treated with lenalidomide and dexamethasone followed by maintenance lenalidomide. He remains in haematologic remission and in complete recovery of functional status 3.5 years after diagnosis. This case supports the long-term use of lenalidomide in patients with POEMS syndrome.

La pêche au calmar à Nhatrang

Squid fishing is a very important economic activity in many far eastern countries. One of the reasons seems to be an easy process for conservation (dried squid) and high demand from the Chinese market.

Impacts of Deepwater Horizon oil and associated dispersant on early development of the Eastern oyster Crassostrea virginica

The explosion of the Deepwater Horizon (DWH) oil platform resulted in large amounts of crude oil and dispersant Corexit 9500A® released into the Gulf of Mexico and coincided with the spawning season of the oyster, Crassostrea virginica. The effects of exposing gametes and embryos of C. virginica to dispersant alone (Corexit), mechanically (HEWAF) and chemically dispersed (CEWAF) DWH oil were evaluated. Fertilization success and the morphological development, growth, and survival of larvae were assessed. Gamete exposure reduced fertilization (HEWAF: EC201 h = 1650 μg tPAH50 L− 1; CEWAF: EC201 h = 19.4 μg tPAH50 L− 1; Corexit: EC201 h = 6.9 mg L− 1). CEWAF and Corexit showed a similar toxicity on early life stages at equivalent nominal concentrations. Oysters exposed from gametes to CEWAF and Corexit experienced more deleterious effects than oysters exposed from embryos. Results suggest the presence of oil and dispersant during oyster spawning season may interfere with larval development and subsequent recruitment.

The Evolution of Massive Young Stellar Objects in the Large Magellanic Cloud

This thesis presents an analysis of the largest catalog to date of infrared spectra of massive young stellar objects in the Large Magellanic Cloud. Evidenced by their very different spectral features, the luminous objects span a range of evolutionary states from those most embedded in their natal molecular material to those that have dissipated and ionized their surroundings to form compact HII regions and photodissociation regions. We quantify the contributions of the various spectral features using the statistical method of principal component analysis. Using this analysis, we classify the YSO spectra into several distinct groups based upon their dominant spectral features: silicate absorption (S Group), silicate absorption and fine-structure line emission (SE), polycyclic aromatic hydrocarbon (PAH) emission (P Group), PAH and fine-structure line emission (PE), and only fine-structure line emission (E). Based upon the relative numbers of sources in each category, we are able to estimate the amount of time massive YSOs spend in each evolutionary stage. We find that approximately 50% of the sources have ionic fine-structure lines, indicating that a compact HII region forms about half-way through the YSO lifetime probed in our study. Of the 277 YSOs we collected spectra for, 41 have ice absorption features, indicating they are surrounded by cold ice-bearing dust particles. We have decomposed the shape of the ice features to probe the composition and thermal history of the ice. We find that most the CO2 ice is embedded a polar ice matrix that has been thermally processed by the embedded YSO. The amount of thermal processing may be correlated with the luminosity of the YSO. Using the Australia Telescope Compact Array, we imaged the dense gas around a subsample of our sources in the HII complexes N44, N105, N113, and N159 using HCO+ and HCN as dense gas tracers. We find that the molecular material in star forming environments is highly clumpy, with clumps that range from subparsec to ~2 parsecs in size and with masses between 10^2 to 10^4 solar masses. We find that there are varying levels of star formation in the clumps, with the lower-mass clumps tending to be without massive YSOs. These YSO-less clumps could either represent an earlier stage of clump to the more massive YSO-bearing ones or clumps that will never form a massive star. Clumps with massive YSOs at their centers have masses larger than those with massive YSOs at their edges, and we suggest that the difference is evolutionary: edge YSO clumps are more advanced than those with YSOs at their centers. Clumps with YSOs at their edges may have had a significant fraction of their mass disrupted or destroyed by the forming massive star. We find that the strength of the silicate absorption seen in YSO IR spectra feature is well-correlated with the on-source HCO+ and HCN flux densities, such that the strength of the feature is indicative of the embeddedness of the YSO. We estimate that ~40% of the entire spectral sample has strong silicate absorption features, implying that the YSOs are embedded in circumstellar material for about 40% of the time probed in our study.

La pêche aux matières explosives

Fishing with explosives dates back to previous times. It was practiced by few Vietnamese fishermen. The practice is widespread in the country during the last fifteen years due to the increasing availability of explosives. Certainly this method gives some significant advantages: it is easy to apply, inexpensive and promptly profitable. But we cannot underestimate the incalculable damages caused by bursting, disorder and desolation. Some of our fishermen, attracted by immediate gain, accomplished a work of terrible devastation. The following paper does not aim to encourage fishermen to develop and modernize fishing methods but it gives the results of an investigation on dangerous fishing methods.
