Utilisation des formulaires de niveaux d’interventions médicales (NIM) en fin de vie chez les patients qui décèdent en milieu hospitalier au Québec

Ce mémoire porte sur l’utilisation des niveaux d’interventions médicales (NIM) en centre hospitalier (CH) au Québec. Les NIM sont des formulaires organisés sous forme d’échelle, qui ont été développés afin de faciliter la prise de décision en lien avec la réanimation, les traitements de maintien en vie et de prolongation de la vie, et les soins à offrir. L’objectif de ce mémoire est d’offrir un portrait de l’utilisation actuelle des NIM au Québec en CH afin d’émettre des recommandations pour les professionnels de la santé, les institutions et les décideurs politiques. Dans un premier temps, un article de recension des écrits est présenté afin de situer les concepts associés aux NIM avec les problèmes actuellement vécus, par exemple le grand nombre de patients qui décèdent en CH, les problèmes de communication entre les professionnels de la santé, les patients et leur famille, les difficultés liées à la prise de décision en fin de vie et les délais liés aux ordonnances de non-réanimation. Dans un deuxième temps, le second article présente les résultats de recherche. Afin d’établir le portrait de l’utilisation des NIM en CH, un audit de 299 dossiers de patients adultes, décédés dans trois CH a été entrepris. Le cadre éthique d’analyse des résultats est l’approche par principes. Bien que l’utilisation des NIM peut différer sur certains aspects selon l’hôpital, les NIM sont un système efficace pour promouvoir le respect de l’autonomie des patients, la bienfaisance et le caring, mais ceux-ci ne protègent pas contre les problèmes d’iniquité dans l’accès aux soins palliatifs. Afin de faciliter et promouvoir leur utilisation, il est recommandé de standardiser les échelles de NIM à travers la province et les institutions et d’émettre des lignes directrices d’utilisation claires. Également, une plus grande formation pour les professionnels de la santé et l’inclusion d’un membre de l’équipe interdisciplinaire permettraient aux professionnels d’être mieux outillés pour les discussions difficiles et pour la prise de décision, et encourageraient la pratique interdisciplinaire.

Sub-Lethal effects of heavy metals on perna indica ( Kuriakose & Nair) and donax incarnatus gmelin

The present scientific investigation of the effects of copper, mercury and cadmium has focussed on their effects on two commercially important marine bivalve species, Perna indica (brown mussel) and Donax incarnatus (wedge clam), conspicuous representatives of the tropical intertidal areas. The investigation centred around delineating the cause and effects of heavy metal stress, individually and in combination on these species under laboratory conditions. A clear understanding of the cause and effect can be had only if laboratory experiments are conducted employing sub-lethal concentrations of the above toxicants. Therefore, during the course of the investigation, sub-lethal concentrations of copper, mercury and cadmium were employed to assess the concentration dependent effects on survival, ventilation rate, O:N ratio and tissues. The results obtained are compared with the already available information and partitioned in sections to make a meaningful presentation.The thesis is presented in five chapters comprising INTRODUCTION, ACUTE TOXICITY, VENTILATION RATE, OXYGEN : NITROGEN RATIO and HISTOPATHOLOGY. Each chapter has been divided into various sections such as INTRODUCTION, REVIEW OF LITERATURE, MATERIAL AND METHODS, RESULTS and DISCUSSION

Toxicity, accumulation and depuration of heavy metalsin the brown mussel perna indica

In this thesis certain important aspects of heavy metal toxicity have been worked out. Recent studies have clearly shown that when experimental media contained more than one heavy metals, such metals could conspicuously influence the toxic reaction of the animals both in terms of quantity and nature. The experimental results available on individual metal toxicity show that, in majority of such results, unrealistically high concentrations of dissolved metals are involved. A remarkable number of factors have been shown to influence metal toxicity such as various environmental factors particularly temperature and salinity, the condition of the organism and the ability of some of the marine organisms to adapt to metallic contamination. Further, some of the more sensitive functions like embryonic and larval development, growth and fecundity, oxygen utilization and the function of various enzymes are found to be demonstrably sensitive in the presence of heavy metals. However, some of the above functions could be compensated for by adaptive process. If it is assumed that the presence of a single metal in higher concentrations could affect the life function of marine animals, more than one metal in the experimental media should manifest such effects in a greater scale. Commonly known as synergism or more than additivity, majority of heavy metals bring about synergistic reaction .The work presented in this thesis comprises lethal and sublethal toxicities of different salt forms of copper and silver on the brown mussel Perna indica. during the present investigation sublethal concentrations of copper and silver in their dent effects on survival, oxygen consumption, filtration, accumulation and depuration on Perna indica. The results are presented under different sections to make the presentation meaningful .

Niveles de hemoglobina en los que se indica transfundir en el Hospital Universitario Fundación Santa Fe de Bogotá

Introducción: En los pacientes críticamente enfermos la terapia transfusional es una práctica común. Dentro de los estudios realizados no se han incluido a las ciudades a mayor altura. Este estudio pretende determinar los niveles de hemoglobina sobre los cuales se está transfundiendo a los pacientes en la unidad de cuidados intensivos del Hospital Universitario Fundación Santa Fe de Bogotá a 2600 metros sobre el nivel del mar, para determinar si los niveles de hemoglobina a los que se transfunde a nuestra altura son los óptimos. Métodos: Se realizó un estudio descriptivo retrospectivo, de los pacientes que fueron hospitalizados en la Unidad de Cuidado Intensivo del Hospital Universitario Fundación Santa Fe de Bogotá a partir del 01 de Junio de 2011 y hasta el 31 de Mayo de 2012. Resultados: Del total de los registros analizados el 13,8% de los pacientes presentaron una hemoglobina ≤ 7 y todos fueron transfundidos con glóbulos rojos; y en el rango de 7,1-9 se presentó el mayor porcentaje de transfusión. Se observó que los pacientes con hemoglobina ≤ 7 tienen 18,8 veces mayor riego de fallecimiento, lo que fue estadísticamente significativo (p:0,000). Conclusiones: Encontramos que la terapia transfusional en la unidad de cuidado intensivo, se realiza de acuerdo a recomendaciones dadas por las guías de manejo universalmente aceptadas. Dentro de los resultados de nuestro estudio podemos resaltar una tasa de mortalidad más alta en los pacientes en los cuales se instaura terapia transfusional con un nivel de hemoglobina por debajo de 7g/dl.

Política de educação em cidadania e relações internacionais : aplicação de um modelo indiano no Brasil

Este trabalho teve por objetivo apresentar os aspectos relacionados com o impacto provocado pelo Programa de Educação em Valores Humanos nas crianças e seus familiares, nos professores, coordenadores, diretores e voluntários que vivenciaram essa metodologia educacional criada por Sathya Sai Baba, nas escolas de Vila Isabel e Ribeirão Preto no ano de 2008. Em primeiro momento, foi necessário definir, mesmo de uma maneira geral, o conceito de valor, chegando ao específico de valores humanos. Buscou-se a relação direta com as religiões, traçando um paralelo entre a sua origem e a influência das religiões nos valores humanos e principalmente na maneira de se comportar dos indivíduos socialmente. Discutiu-se a educação no Brasil, com sua cronologia e influências, a educação na Índia e traçou-se um paralelo entre ambas. Viu-se que a educação brasileira precisava passar por uma transformação e que a implantação de um programa como este está relacionada ao querer por parte da gestão, já que ele agrega valor ao conteúdo formal. Por fim, apresentou-se a parte central do trabalho que é o Programa de Educação em Valores Humanos – PEVH, com sua origem, metodologias, técnicas, organizações mundiais e brasileiras que trabalham parcialmente ou na íntegra com o programa e os impactos provocados por quem vive os valores humanos. Os dados foram apresentados através da pesquisa bibliográfica e de campo que, juntos, confirmaram a importância do resgate dos valores humanos e da sua prática cotidiana na transformação da sociedade, por meio do processo educacional.

The endophytic fungus Piriformospora indica protects wheat from Fusarium crown rot disease in simulated UK autumn conditions

The root endophytic fungus Piriformospora indica (Sebacinacea) forms mutualistic symbioses with a broad range of host plants, increasing their biomass production and resistance to fungal pathogens. We evaluated the effect of P. indica on Fusarium crown rot disease of wheat, under in vitro and glasshouse conditions. Interaction of P. indica and Fusarium isolates under axenic culture conditions indicated no direct antagonistic activity of P. indica against Fusarium isolates. Seedlings of wheat were inoculated with P. indica and pathogenic Fusarium culmorum or F. graminearum and grown in sterilised soil-free medium or in a non-sterilised mix of soil and sand. Fusarium alone reduced emergence and led to visible browning and reduced root growth. Roots of seedlings in pots inoculated with both Fusarium isolates and P. indica were free of visible symptoms; seed emergence and root biomass were equivalent to the uninoculated. DNA was quantified by real-time polymerase chain reaction (qPCR). The ratio of Fusarium DNA to wheat DNA rose rapidly in the plants inoculated with Fusarium alone; isolates and species were not significantly different. P. indica inoculation reduced the ratio of Fusarium to host DNA in the root systems. The reduction increased with time. The ratio of P. indica to wheat DNA initially rose but then declined in root systems without Fusarium. With Fusarium, the ratio rose throughout the experiment. The absolute amount of Fusarium DNA in root systems increased in the absence of P. indica but was static in plants co-inoculated with P. indica.

Piriformospora indica reduces Fusarium head blight disease severity and mycotoxin DON contamination in wheat under UK weather conditions

Piriformospora indica (Sebacinaceae) is a cultivable root endophytic fungus. It colonises the roots of a wide range of host plants. In many settings colonisation promotes host growth, increases yield and protects the host from fungal diseases. We evaluated the effect of P. indica on Fusarium head blight (FHB) disease of winter (cv. Battalion) and spring (cv. Paragon, Mulika, Zircon, Granary, KWS Willow and KWS Kilburn) wheat and consequent contamination by the mycotoxin deoxynivalenol (DON) under UK weather conditions. Interactions of P. indica with an arbuscular mycorrhizal fungus (Funneliformis mosseae), fungicide application (Aviator Xpro) and low and high fertiliser levels were considered. P. indica application reduced FHB disease severity and incidence by 70%. It decreased mycotoxin DON concentration of winter and spring wheat samples by 70% and 80% respectively. P. indica also increased above ground biomass, 1000 grain weight and total grain weight. P. indica reduced disease severity and increased yield in both high and low fertiliser levels. The effect of P. indica was compatible with F. mosseae and foliar fungicide application. P. indica did not have any effects on plant tissue nutrients. These results suggest that P. indica might be useful in biological control of Fusarium diseases of wheat.

Crystalline structure of mangiferin, a C-glycosyl-substituted 9H-xanthen-9-one isolated from the stem bark of Mangifera indica

The crystalline structure of mangiferin (= 2-beta-D-glucopyranosyl-1,3,6,7-tetrahydroxy-9H-xanthen-9-one; 1), a biologically active xanthenone C-glycoside, isolated from the stem bark of Mangifera indica (Anacardiaceae), was unambiguously determined by single-crystal X-ray diffraction (XRD). The crystal structure is summarized as follows: triclinic, P1, a = 7.6575(5), b = 11.2094(8), c = 11.8749(8) angstrom, alpha = 79.967(5), beta = 87.988(4), gamma = 72.164(4)degrees, V = 955.3(1) angstrom(3), and Z = 2. The structure also shows two molecules in the asymmetric unit cell and five crystallization H2O molecules. The packing is stabilized by several intermolecular H-bonds involving either the two symmetry-independent mangiferin molecules 1a and 1b, or the H2O ones.
