Family members' perceptions of nurse caring behaviours in the intensive care unit

La présence de membres de la famille dans les milieux de soins critiques a augmentée graduellement au cours des dernières années. La présente recherche visait à décrire la perception que les membres de la famille avait eu à l’égard des comportements de caring des infirmières lors de leur visite aux soins intensifs. Plus spécifiquement, ce projet avait pour but d’explorer les différences entre les perceptions de membres de la famille dont le proche était hospitalisé pour une blessure traumatique versus une maladie grave non-traumatique. Les différences ont aussi été examinées selon certaines caractéristiques personnelles d’un membre de la famille soit leur genre, leur expérience antérieure de visites aux soins intensifs, leur âge et leur perception de la gravité du problème de santé de leur proche. Le cadre de référence de cette étude était basé sur les facteurs caratifs proposés par Watson (1985). L’importance et la satisfaction des membres de la famille à l’égard des comportements de caring de la part des infirmières ont été mesurées par les versions française et anglaise adaptées du Caring Behaviors Assessment (CBA) (Cronin & Harrison, 1988). Les données ont été analysées en utilisant les techniques d’analyse MANOVA et des tests de corrélation de Pearson. En général, les résultats indiquent que les membres de la famille rapportent des degrés d’importance et de satisfaction similaires selon que leur proche était hospitalisé pour une blessure traumatique ou une maladie grave non-traumatique. Peu de différences émergent selon les caractéristiques personnelles des membres de la famille. Un coefficient de corrélation significatif (0.36, p = 0.012) existe entre la perception des membres de la famille de la gravité du problème de santé, et l’importance de la dimension ‘réponses aux besoins’. Par ailleurs, les comportements de caring regroupés dans la dimension ‘réponses aux besoins’ ont été perçus comme étant les plus importants et les membres de familles étaient très satisfaits des comportements de caring des infirmières. Cette étude fournit des pistes pour l’enseignement, la clinique et la recherche et met en lumière la perception des membres de la famille des soins infirmiers humains chez des proches hospitalisés dans une unité de soins intensifs.

Intracellular trafficking of protease : Activated Receptor 2 (PAR2) by members of sorting nexins family

Le dogme voulant que les récepteurs couplés aux protéines G (GPCRs) activent des voies de signalisation seulement lorsqu’ils sont localisés à la membrane plasmatique, a récemment été remis en question. Des données récentes indiquent que certains GPCRs peuvent également induire une réponse intracellulaire à partir des compartiments intracellulaires dont le noyau. Les récepteurs activés par la protéase (PAR) sont des membres de la famille GPCR. Les PARs sont activés par le clivage de la partie N–terminale du récepteur ce qui permet au ligand attaché sur le récepteur de se lier à sa poche réceptrice. Quatre PARs ont été décrits : PAR1, PAR2, PAR3 et PAR4. PAR2 peut susciter des effets mitogéniques et participer aux processus comme l’angiogenèse et l'inflammation. Alors que beaucoup d'effets intracellulaires de PAR2 peuvent être expliqués lorsqu’il est localisé à la membrane plasmatique, une fonction intracrine de PAR2 a aussi été proposée. Pourtant les mécanismes par lesquels PAR2 peut provoquer l’expression de gènes ciblés sont toujours inconnus. Le but de notre étude était de vérifier l’existence d’une population nucléaire de PAR2. Nous avons également émis l’hypothèse que les voies activées par l’activation de PAR2 dépendent de sa localization cellulaire. En utilisant des techniques de microscopie confocale et de "Western Blot" nous avons démontré la présence d’une population nucléaire de PAR2. À la suite de la stimulation de PAR2, nous avons observé une augmentation de la translocation du récepteur de la membrane plasmatique au noyau. En utilisant la technique de "RT – PCR", nous avons observé des rôles différents de PAR2 à la surface de la cellule et du noyau dans l’initiation de l’expression des gènes. Afin d’identifier les mécanismes responsables de la translocation nucléaire de PAR2, nous avons évalué l’implication des membres de la famille de "Sorting Nexins (SNX)" dans la translocation nucléaire de PAR2. "Sorting Nexins" est un groupe de protéines avec des fonctions de transport bien établies. SNX1 et SNX2 ont été identifiés comme responsables du transfert de PAR1 vers les lysosomes. SNX11 n'a pas encore été étudié et nous avons émis l’hypothèse qu'il pourrait être un autre membre de la famille des SNX impliqué dans la signalisation de PAR2. Pour ce faire, nous avons développé des "knockdowns" stables pour SNX1, SNX2 et SNX11 dans les cellules HEK293. En utilisant les essais d’immunofluorescence, "Western Blot" et de cytométrie en flux, nous avons déterminé que tous les trois membres du groupe SNX sont des partenaires d'interaction de PAR2. Toutefois, seul SNX11 se co-localise avec son partenaire au noyau et est responsable de sa translocation nucléaire. Les expériences de "RT - PCR" sur les lignées de cellule de SNXs "knockdowns" ont démontré que la fonction de PAR2 nucléaire dépend surtout de SNX11; néanmoins SNX1 et SNX2 peuvent aussi l’influencer, suggérant qu'ils font aussi partie du réseau signalétique de PAR2. En conclusion, PAR2 est déplacé de la membrane plasmatique à la membrane nucléaire après sa stimulation avec un agoniste. La translocation nucléaire de PAR2 par un mécanisme impliquant SNX11, initie des effets intracellulaires différents de sa signalisation membranaire. Mots clés : récepteurs couplés à la protéine G, “Sorting Nexins”, récepteurs activés par la protéase, translocation nucléaire, membrane nucléaire, signal nucléaire.

Mental health treatment seeking by military members with posttraumatic stress disorder : findings on rates, characteristics, and predictors from a nationally representative Canadian military sample

Objective: The goal of this study was to identify rates, characteristies, and predictors of mental health treatment seeking by military members with posttraumatic stress disorder (PTSD). Method: Our sample was drawn from the 2002 Canadian Community Health Survey-Canadian Forces Supplement (CCHS-CF) dataset. The CCHS-CF is the first epidemiologic survey of PTSD and other mental health conditions in the Canadian military and includes 8441 nationally representative Canadian Forces (CF) members. Of those, 549 who met the criteria for lifetime PTSD were included in our analyses. To identify treatment rates and characteristics, we examined frequency of treatment contact by professional and facility type. To identify predictors of treatment seeking, we conducted a binary logistic regression with lifetime treatment seeking as the outcome variable. Results: About two-thirds of those with PTSD consulted with a professional regarding mental health problems. The most frequently consulted professionals, during both the last year and lifetime, included social workers and counsellors, medical doctors and general practitioners, and psychiatrists. Consultations during the last year most often took place in a CF facility. Treatment seeking was predicted by cumulative lifetime trauma exposure, index traumatic event type, PTSD symptom interference, and comorbid major depressive disorder. Those with comorbid depression were 3.75 times more likely to have sought treatment than those without. Conclusions: Although a significant portion of military members with PTSD sought mental health treatment, 1 in 3 never did. Trauma-related and illness and (or) need factors predicted treatment seeking. Of all the predictors of treatment seeking, comorbid depression most increased the likelihood of seeking treatment.

lntemet utilization and academic activities of faculty members in the universities of Kerala : an analytical study

This thesis Entitled Internet Utilization and Academic Activities of Faculty Members in the Universities of kerala: an analytical study. Today, scientific research is throwing up new discoveries, inventions and vistas by the hour. We are witnessing a veritable knowledge explosion. It is important for members of university faculty members to keep abreast of it for giving up-t-date information to their students about the new development in the subject of their study. The internet is an invaluable tool for achieving it. Most of the universities have sufficient internet facility, but the accessibility to all the faculty members is not adequate. University Libraries also provides standard supplementary service in the internet area. This study indicates differential level of awareness and utilization of the internet services by the faculty members in the areas of teaching, research and publication. However the overall impression is that the awareness and utilization is inadequate. This point to the urgent need to devise programs and schemes to promote internet utilization among the faculty members. The suggestions indicate the key areas that deserve attention by policy makers and administrators. Thanks to the internet, every new development in every field of study is just a click away for faculty members, research scholars and students.

Behavior of geopolymer concrete exposed to elevated temperatures

The research in the area of geopolymer is gaining momentum during the past 20 years. Studies confirm that geopolymer concrete has good compressive strength, tensile strength, flexural strength, modulus of elasticity and durability. These properties are comparable with OPC concrete.There are many occasions where concrete is exposed to elevated temperatures like fire exposure from thermal processor, exposure from furnaces, nuclear exposure, etc.. In such cases, understanding of the behaviour of concrete and structural members exposed to elevated temperatures is vital. Even though many research reports are available about the behaviour of OPC concrete at elevated temperatures, there is limited information available about the behaviour of geopolymer concrete after exposure to elevated temperatures. A preliminary study was carried out for the selection of a mix proportion. The important variable considered in the present study include alkali/fly ash ratio, percentage of total aggregate content, fine aggregate to total aggregate ratio, molarity of sodium hydroxide, sodium silicate to sodium hydroxide ratio, curing temperature and curing period. Influence of different variables on engineering properties of geopolymer concrete was investigated. The study on interface shear strength of reinforced and unreinforced geopolymer concrete as well as OPC concrete was also carried out. Engineering properties of fly ash based geopolymer concrete after exposure to elevated temperatures (ambient to 800 °C) were studied and the corresponding results were compared with those of conventional concrete. Scanning Electron Microscope analysis, Fourier Transform Infrared analysis, X-ray powder Diffractometer analysis and Thermogravimetric analysis of geopolymer mortar or paste at ambient temperature and after exposure to elevated temperature were also carried out in the present research work. Experimental study was conducted on geopolymer concrete beams after exposure to elevated temperatures (ambient to 800 °C). Load deflection characteristics, ductility and moment-curvature behaviour of the geopolymer concrete beams after exposure to elevated temperatures were investigated. Based on the present study, major conclusions derived could be summarized as follows. There is a definite proportion for various ingredients to achieve maximum strength properties. Geopolymer concrete with total aggregate content of 70% by volume, ratio of fine aggregate to total aggregate of 0.35, NaOH molarity 10, Na2SiO3/NaOH ratio of 2.5 and alkali to fly ash ratio of 0.55 gave maximum compressive strength in the present study. An early strength development in geopolymer concrete could be achieved by the proper selection of curing temperature and the period of curing. With 24 hours of curing at 100 °C, 96.4% of the 28th day cube compressive strength could be achieved in 7 days in the present study. The interface shear strength of geopolymer concrete is lower to that of OPC concrete. Compared to OPC concrete, a reduction in the interface shear strength by 33% and 29% was observed for unreinforced and reinforced geopolymer specimens respectively. The interface shear strength of geopolymer concrete is lower than ordinary Portland cement concrete. The interface shear strength of geopolymer concrete can be approximately estimated as 50% of the value obtained based on the available equations for the calculation of interface shear strength of ordinary portland cement concrete (method used in Mattock and ACI). Fly ash based geopolymer concrete undergoes a high rate of strength loss (compressive strength, tensile strength and modulus of elasticity) during its early heating period (up to 200 °C) compared to OPC concrete. At a temperature exposure beyond 600 °C, the unreacted crystalline materials in geopolymer concrete get transformed into amorphous state and undergo polymerization. As a result, there is no further strength loss (compressive strength, tensile strength and modulus of elasticity) in geopolymer concrete, whereas, OPC concrete continues to lose its strength properties at a faster rate beyond a temperature exposure of 600 °C. At present no equation is available to predict the strength properties of geopolymer concrete after exposure to elevated temperatures. Based on the study carried out, new equations have been proposed to predict the residual strengths (cube compressive strength, split tensile strength and modulus of elasticity) of geopolymer concrete after exposure to elevated temperatures (upto 800 °C). These equations could be used for material modelling until better refined equations are available. Compared to OPC concrete, geopolymer concrete shows better resistance against surface cracking when exposed to elevated temperatures. In the present study, while OPC concrete started developing cracks at 400 °C, geopolymer concrete did not show any visible cracks up to 600 °C and developed only minor cracks at an exposure temperatureof 800 °C. Geopolymer concrete beams develop crack at an early load stages if they are exposed to elevated temperatures. Even though the material strength of the geopolymer concrete does not decrease beyond 600 °C, the flexural strength of corresponding beam reduces rapidly after 600 °C temperature exposure, primarily due to the rapid loss of the strength of steel. With increase in temperature, the curvature at yield point of geopolymer concrete beam increases and thereby the ductility reduces. In the present study, compared to the ductility at ambient temperature, the ductility of geopolymer concrete beams reduces by 63.8% at 800 °C temperature exposure. Appropriate equations have been proposed to predict the service load crack width of geopolymer concrete beam exposed to elevated temperatures. These equations could be used to limit the service load on geopolymer concrete beams exposed to elevated temperatures (up to 800 °C) for a predefined crack width (between 0.1mm and 0.3 mm) or vice versa. The moment-curvature relationship of geopolymer concrete beams at ambient temperature is similar to that of RCC beams and this could be predicted using strain compatibility approach Once exposed to an elevated temperature, the strain compatibility approach underestimates the curvature of geopolymer concrete beams between the first cracking and yielding point.
