Conhecimentos sobre a RNCCI: um estudo exploratório sobre a perceção dos alunos do curso de enfermagem

A Rede Nacional de Cuidados Continuados (RNCCI) foi criada em 2006 pelo decreto-lei nº 101/2006, no âmbito do Ministério da Saúde e da Segurança Social. A RNCCI tem como missão prestar os cuidados adequados, de saúde e apoio social, a todas as pessoas que, independentemente da idade, se encontrem em situação de dependência, e articula-se com os serviços de saúde e sociais já existentes. Para cumprir a sua missão, a RNCCI, necessita de uma equipa multidisciplinar, na qual integram vários profissionais, tais como: médicos, enfermeiros, assistentes sociais, psicólogos, entre muitos outros, de entre estes os enfermeiros são os profissionais que maior percentagem detêm na constituição da mesma. Daí que seja pertinente a realização de estudos de investigação, com enfermeiros e estudantes de enfermagem, nesta nova valência de cuidados. O presente estudo incide sobre os conhecimentos dos estudantes de enfermagem sobre a RNCCI, que frequentam o terceiro e quarto ano na Escola Superior de Saúde do Instituto Politécnico de Bragança. Sendo a questão de investigação deste estudo: “Quais os conhecimentos dos alunos de enfermagem do terceiro e quarto ano da licenciatura em enfermagem sobre a RNCCI?”. Foi realizado um estudo de natureza quantitativa, descritivo, correlacional, num plano transversal. Optou-se por um processo de amostragem não probabilística de conveniência, que refletisse a distribuição da população por ano de escolaridade. Assim, considerou-se uma amostra de 120 alunos (75 % da população), selecionados acidentalmente, visando a disponibilidade, rapidez e o menor custo na recolha de dados. Concluiu-se que os alunos de enfermagem de uma forma geral apresentam conhecimentos sobre a RNCCI. Destacando-se uma percentagem de 90% de respostas corretas referentes sobre a RNCCI. No entanto 75% dos alunos responderam erradamente às afirmações relacionados com o processo de referenciação e tipologia das respostas da RNCCI. Comparando estes resultados com estudos realizados com enfermeiros que exercem funções na RNCCI, verifica-se que os alunos não apresentam conhecimentos suficientes para desencadear funções ou processos relacionados com a RNCCI, apesar de terem conhecimentos gerais da mesma, pois apresentam consideráveis falhas desde logo no processo de referenciação, assim como profissionais que já trabalham na área. Tais factos constatados salientam a importância de formação teórica e/ou prática, no plano curricular da licenciatura de enfermagem, preparando os futuros enfermeiros para exercerem as suas funções na RNCCI, e não só. Pois os enfermeiros que trabalham nos cuidados de saúde primários e secundários, também eles necessitam de ter conhecimentos sobre a RNCCI, verificando-se muito frequentemente é durante o internamento que se inicia o processo de referenciação. Sugerindo que o conhecimento dos alunos sobre a RNCCI, são adquiridos na sua maioria durante a realização do ensino clínico, onde acompanham este tipo de atividades. Embora a formação base da licenciatura, permita uma vasta aquisição de competências teórico-práticas, e a integração de formação sobre a RNCCI, seja considerada pelos alunos de enfermagem, como importante ou muito importante, a mesma pode considerar-se atualmente praticamente inexistente.

Les mécanismes sous-jacents aux effets pathologiques cardiaques de l’angiotensine II dans le remodelage électrique et contractile entre les sexes

L’insuffisance cardiaque (IC) est associée à un taux de mortalité et d’hospitalisations élevé causant un fardeau économique important. Les deux causes majeures de décès de l’IC sont les arythmies ventriculaires létales et les sidérations myocardiques. Il est maintenant reconnu que l’angiotensine II (ANGII) est l'un des principaux médiateurs de l’IC. Ses effets délétères découlent de l’activation du récepteur de type 1 de l’ANGII (AT1) et entraînent le développement d’hypertrophie. Toutefois, son rôle dans la genèse d’arythmies demeure incompris. De ce fait, l'étude des mécanismes électriques et contractiles sous-jacents aux effets pathologiques de l’ANGII s’avère essentielle afin de mieux comprendre et soigner cette pathologie. Il est souvent perçu que les femmes sont protégées envers les maladies cardiovasculaires. Cependant, le nombre total de femmes décédant d’IC est plus grand que le nombre d’hommes. Également, l’impact des facteurs de risque diffère entre chaque sexe. Ces différences existent, mais les mécanismes sous-jacents sont encore peu connus. De plus, les femmes reçoivent fréquemment un diagnostic ou un traitement inapproprié en raison d’un manque d’information sur les différences entre les sexes dans la manifestation d’une pathologie. Ce manque de données peut découler du fait que les sujets de sexe féminin sont souvent sous-représentés dans les essais cliniques ou la recherche fondamentale ce qui a grandement limité l’avancement de nos connaissances sur ~50 % de la population. Ainsi, il semble plus que nécessaire d’approfondir notre compréhension des différences entre les sexes, notamment dans la progression de l’IC. L’utilisation d’un modèle de souris transgénique surexprimant le récepteur AT1 (souris AT1R) a permis d’étudier les changements électriques, structurels et contractiles avant et après le développement d’hypertrophie. Premièrement, chez les souris AT1R mâles, un ralentissement de la conduction ventriculaire a été observé indépendamment de l’hypertrophie. Ce résultat était expliqué par une réduction de la densité du courant Na+, mais pas de l’expression du canal. Ensuite, le rôle des protéines kinases C (PKC) dans la régulation du canal Na+ par l’ANGII a été exploré. Les évidences ont suggéré que la PKCα était responsable de la modulation de la diminution du courant Na+ chez les souris AT1R mâles et dans les cardiomyocytes humains dérivés de cellules souches induites pluripotentes (hiPSC-CM) en réponse à un traitement chronique à l’ANGII. Ensuite, les différences entre les sexes ont été comparées chez la souris AT1R. Une plus grande mortalité a été constatée chez les femelles AT1R suggérant qu’elles sont plus sensibles à la surexpression de AT1R. Le remodelage électrique ventriculaire a donc été comparé entre les souris AT1R des deux sexes. Les courants ioniques étaient altérés de façon similaire entre les sexes excluant ainsi leur implication dans la mortalité plus élevée chez les femelles. Ensuite, l’homéostasie calcique et la fonction cardiaque ont été étudiées. Il a été démontré que les femelles développaient une hypertrophie et une dilatation ventriculaire plus sévère que les mâles. De plus, les femelles AT1R avaient de petits transitoires calciques, une extrusion du Ca2+ plus lente ainsi qu’une augmentation de la fréquence des étincelles Ca2+ pouvant participer à des troubles contractiles et à la venue de post-dépolarisations précoces. En conclusion, l’ANGII est impliquée dans le remodelage électrique, structurel et calcique associé à l'émergence de l’IC. De surcroît, ces altérations affectent plus sévèrement les femelles soulignant la présence de différences entre les sexes dans le développement de l’IC.

Quand le tabac s’affiche au Parlement. Débats sur les limitations en matière de publicité de la cigarette dans les cantons romands

Cette contribution porte sur les politiques d’interdiction de la publicité pour les cigarettes, l’un des axes-clé de la prévention structurelle du tabagisme. Nous nous intéressons à la rapide et récente dissémination de ces politiques dans les cantons suisses, qui contraste avec l’immobilisme fédéral. Nous attirons alors l’attention sur le rôle moteur du niveau d’action cantonal, au sein d’un domaine de santé publique qui avait pourtant connu, cette dernière décennie, ses plus formidables avancées dans le sillage de mouvements d’essence supranationaux. L’analyse des débats parlementaires romands nous permet finalement d’élaborer une typologie des argumentaires en présence, et de mettre en évidence les axes les plus à mêmes de provoquer une scission gauche/droite.

Community-based interventions for the prevention of burns and scalds in children

Background Burns and scalds are a significant cause of morbidity and mortality in children. Successful counter-measures to prevent burn and scald-related injury have been identified. However, evidence indicating the successful roll-out of these counter-measures into the wider community is lacking. Community-based interventions in the form of multi-strategy, multi-focused programmes are hypothesised to result in a reduction in population-wide injury rates. This review tests this hypothesis with regards to burn and scald injury in children. Objectives To assess the effects of community-based interventions, defined as coordinated, multi-strategy initiatives, for reducing burns and scalds in children aged 14 years and under. Search strategy We searched the Cochrane Injuries Group's specialised register, CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, National Research Register and the Web of Knowledge. We also handsearched selected journals and checked the reference lists of selected publications. The searches were last updated in May 2007. Selection criteria Included studies were those that reported changes in medically attended burn and scald-related injury rates in a paediatric population (aged 14 years and under), following the implementation of a controlled community-based intervention. Data collection and analysis Two authors independently assess studies for eligibility and extracted data. Due to heterogeneity between the included studies, a pooled analysis was not appropriate. Main results Of 39 identified studies, four met the criteria for inclusion. Two of the included studies reported a significant decrease in paediatric burn and scald injury in the intervention compared with the control communities. The failure of the other two studies to show a positive result may have been due to limited time-frame for the intervention and/or failure to adequately implement the counter-measures in the communities. Authors' conclusions There are a very limited number of research studies allowing conclusions to be drawn about the effectiveness of community-based injury prevention programmes to prevent burns and scalds in children. There is a pressing need to evaluate high-quality community-based intervention programmes based on efficacious counter-measures to reduce burns and scalds in children. It is important that a framework for considering the problem of burns and scalds in children from a prevention perspective be articulated, and that an evidence-based suite of interventions be combined to create programme guidelines suitable for implementation in communities throughout the world.

Is cannabis a gateway drug? Testing hypotheses about the relationship between cannabis use and the use of other illicit drugs

We outline and evaluate competing explanations of three relationships that have consistently been found between cannabis use and the use of other illicit drugs, namely, ( 1) that cannabis use typically precedes the use of other illicit drugs; and that ( 2) the earlier cannabis is used, and ( 3) the more regularly it is used, the more likely a young person is to use other illicit drugs. We consider three major competing explanations of these patterns: ( 1) that the relationship is due to the fact that there is a shared illicit market for cannabis and other drugs which makes it more likely that other illicit drugs will be used if cannabis is used; ( 2) that they are explained by the characteristics of those who use cannabis; and ( 3) that they reflect a causal relationship in which the pharmacological effects of cannabis on brain function increase the likelihood of using other illicit drugs. These explanations are evaluated in the light of evidence from longitudinal epidemiological studies, simulation studies, discordant twin studies and animal studies. The available evidence indicates that the association reflects in part but is not wholly explained by: ( 1) the selective recruitment to heavy cannabis use of persons with pre-existing traits ( that may be in part genetic) that predispose to the use of a variety of different drugs; ( 2) the affiliation of cannabis users with drug using peers in settings that provide more opportunities to use other illicit drugs at an earlier age; ( 3) supported by socialisation into an illicit drug subculture with favourable attitudes towards the use of other illicit drugs. Animal studies have raised the possibility that regular cannabis use may have pharmacological effects on brain function that increase the likelihood of using other drugs. We conclude with suggestions for the type of research studies that will enable a decision to be made about the relative contributions that social context, individual characteristics, and drug effects make to the relationship between cannabis use and the use of other drugs.

Community-based programmes to prevent falls in children: A systematic review

Objective: We systematically reviewed the literature to examine the evidence for the effectiveness of community-based interventions to reduce fall-related injury in children aged 0-16 years. Methods: We performed a comprehensive search of the literature using the following study selection criteria: community-based intervention study; target population was children aged 0-16 years; outcome measure was fall-related injury rates; and either a community control or historical control was used in the study design. Quality assessment and data abstraction were guided by a standardized procedure and performed independently by two authors. Results: Only six studies fitting the inclusion criteria were identified in our search and only two of these used a trial design with a contemporary community control. Neither of the high quality evaluation studies showed an effect from the intervention and while authors of the remaining studies reported effective falls prevention programmes, the pre- and post-intervention design, uncontrolled for background secular trends, makes causal inferences from these studies difficult. Conclusion: There is a paucity of research studies from which evidence regarding the effectiveness of community-based intervention programmes for the prevention of fall-related injury in children could be based.

Assessing facial approximation accuracy: How do resemblance ratings of disparate faces compare to recognition tests?

In the past, the accuracy of facial approximations has been assessed by resemblance ratings (i.e., the comparison of a facial approximation directly to a target individual) and recognition tests (e.g., the comparison of a facial approximation to a photo array of faces including foils and a target individual). Recently, several research studies have indicated that recognition tests hold major strengths in contrast to resemblance ratings. However, resemblance ratings remain popularly employed and/or are given weighting when judging facial approximations, thus indicating that no consensus has been reached. This study aims to further investigate the matter by comparing the results of resemblance ratings and recognition tests for two facial approximations which clearly differed in their morphological appearance. One facial approximation was constructed by an experienced practitioner privy to the appearance of the target individual (practitioner had direct access to an antemortem frontal photograph during face construction), while the other facial approximation was constructed by a novice under blind conditions. Both facial approximations, whilst clearly morphologically different, were given similar resemblance scores even though recognition test results produced vastly different results. One facial approximation was correctly recognized almost without exception while the other was not correctly recognized above chance rates. These results suggest that resemblance ratings are insensitive measures of the accuracy of facial approximations and lend further weight to the use of recognition tests in facial approximation assessment.

Frequent detection of human rhinoviruses, paramyxoviruses, coronaviruses, and bocavirus during acute respiratory tract infections

Viruses are the major cause of pediatric acute respiratory tract infection (ARTI) and yet many suspected cases of infection remain uncharacterized. We employed 17 PCR assays and retrospectively screened 315 specimens selected by season from a predominantly pediatric hospital-based population. Before the Brisbane respiratory virus research study commenced, one or more predominantly viral pathogens had been detected in 15.2% (n = 48) of all specimens. The Brisbane study made an additional 206 viral detections, resulting in the identification of a microbe in 67.0% of specimens. After our study, the majority of microbes detected were RNA viruses (89.9%). Overall, human rhinoviruses (HRVs) were the most frequently identified target (n=140) followed by human adenoviruses (HAdVs; n = 25), human metapneumovirus (HMPV; n=18), human bocavirus (HBoV; n = 15), human respiratory syncytial virus (HRSV; n = 12), human coronaviruses (HCoVs; n = 11), and human herpesvirus-6 (n = 11). HRVs were the sole microbe detected in 37.8% (n = 31) of patients with suspected lower respiratory tract infection (LRTI). Genotyping of the HRV VP4/VP2 region resulted in a proposed subdivision of HRV type A into sublineages A1 and A2. Most of the genotyped HAdV strains were found to be type C. This study describes the high microbial burden imposed by HRVs, HMPV, HRSV, HCoVs, and the newly identified virus, HBoV on a predominantly paediatric hospital population with suspected acute respiratory tract infections and proposes a new formulation of viral targets for future diagnostic research studies.
