Sistematização da assistencia de enfermagem numa UTI geral: um contributo para a sua implementação

Enquadramento: A Sistematização da Assistência de Enfermagem (SAE) contribui de forma significativa para a qualidade da assistência prestada ao cliente e, as ações de enfermagem, são delineadas e individualizadas, transmitindo maior segurança, estabilidade e veracidade para o cliente e toda a equipe envolvida neste processo. Objetivo: O estudo teve como objetivo identificar os conhecimentos da equipe de enfermagem sobre a SAE e a sua participação nesse processo, revestindo-se em benefícios por sensibilizar a equipe de enfermagem da UTI Geral para a implementação de um modelo de SAE composto pelas etapas do PE: Histórico, Diagnóstico, Prescrição e Evolução de Enfermagem. Metodologia: Trata-se de um estudo descritivo de abordagem quantitativa. Para a colheita de dados utilizamos um questionário elaborado para o efeito. O estudo decorreu entre o período setembro a dezembro de 2014, no Hospital Agamenon Magalhães, Recife, Brasil, numa amostra de 650 profissionais de enfermagem. Resultados: Pelos resultados do estudo verificamos que 84,4% (190) dos profissionais inquiridos demonstram ter conhecimentos sobre a SAE, 97,8% (220) concordam sobre a sua importância no planeamento da assistência e, consequentemente, com a implementação do processo, embora 41,8% (94) não manifestem motivação para trabalhar com a mesma. Conclusão: O estudo da SAE e sua implementação é de suma importância desenvolvendo competências, treinamentos e motivações para que o cuidado possa ser de qualidade. Também há necessidade de estimular e preparar os profissionais de enfermagem para atuarem de forma sistematizada junto do paciente, através do processo de enfermagem, numa relação interpessoal e marcada pela competência científica, técnica e ética.

Rastreio auditivo neonatal universal em Portugal : ponto da situação

Este estudo surgiu com o intuito de conhecer a realidade portuguesa dos programas de deteção e intervenção auditiva precoce no sentido de: compreender o funcionamento dos diferentes programas; analisar o seu nível de eficácia; propor estratégias para melhorar a sua funcionalidade. Para a concretização da investigação foram contatadas 57 hospitais/maternidades. Destas foram obtidas 40 respostas, sendo que em 3 instituições não é atualmente realizado o rastreio auditivo neonatal; 4 não responderam por opção ao questionário; 37 responderam ao questionário, 13 não deram resposta. Todos os dados recolhidos foram posteriormente utilizados para tratamento estatístico, assegurando a sua confidencialidade. Os protocolos de funcionamento dos programas da amostra em estudo são distintos, indo todos ao encontro das recomendações publicadas pelo Grupo de Rastreio e Intervenção da Surdez Infantil. Em 86,5% das instituições estudadas, os programas implementados são universais e a taxa de cobertura está entre os 92% e os 100%, sendo a sua média de 97,8%. Da amostra recolhida, seis instituições referiram não possuir os dados estatísticos do rastreio atualizados e disponíveis. A existência de uma base de dados nacional permitiria conhecer a realidade de todas as instituições, obtendo assim um melhor conhecimento sobre a qualidade de cada programa.

Experimental infections of neonatal mice with cysts of Giardia lamblia clone GS/M-83-H7 are associated with an antigenic reset of the parasite.

Transmission of the protozoan parasite Giardia lamblia from one to another host individuum occurs through peroral ingestion of cysts which, following excystation in the small intestine, release two trophozoites each. Many studies have focused on the major surface antigen, VSP (for variant surface protein), which is responsible for the antigenic variability of the parasite. By using trophozoites of G. lamblia clone GS/M-83-H7 (expressing VSP H7) and the neonatal mouse model for experimental infections, we quantitatively assessed the process of antigenic variation of the parasite on the transcriptional level. In the present study, variant-specific regions identified on different GS/M-83-H7 vsp sequences served as targets for quantitative reverse transcription-PCR to monitor alterations in vsp mRNA levels during infection. Respective results demonstrated that antigenic switching of both the duodenal trophozoite and the cecal cyst populations was associated with a massive reduction in vsp H7 mRNA levels but not with a simultaneous increase in transcripts of any of the subvariant vsp genes analyzed. Most importantly, we also explored giardial variant-type formation and vsp mRNA levels after infection of mice with cysts. This infection mode led to an antigenic reset of the parasite in that a VSP H7-negative inoculum "converted" into a population of intestinal trophozoites that essentially consisted of the original VSP H7 type. This antigenic reset appears to be associated with excystation rather than with a selective process which favors expansion of a residual population of VSP H7 types within the antigenically diversified cyst inoculum. Based on these findings, the VSP H7 type has to be regarded as a predominant variant of G. lamblia clone GS/M-83-H7 which (re-)emerges during early-stage infection and may contribute to an optimal establishment of the parasite within the intestine of the experimental murine host.

Microglial Cells Prevent Hemorrhage in Neonatal Focal Arterial Stroke

Perinatal stroke leads to significant morbidity and long-term neurological and cognitive deficits. The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. To understand whether microglial cells limit injury after neonatal stroke by preserving neurovascular integrity, we subjected postnatal day 7 (P7) rats depleted of microglial cells, rats with inhibited microglial TGFbr2/ALK5 signaling, and corresponding controls, to transient middle cerebral artery occlusion (tMCAO). Microglial depletion by intracerebral injection of liposome-encapsulated clodronate at P5 significantly reduced vessel coverage and triggered hemorrhages in injured regions 24 h after tMCAO. Lack of microglia did not alter expression or intracellular redistribution of several tight junction proteins, did not affect degradation of collagen IV induced by the tMCAO, but altered cell types producing TGFβ1 and the phosphorylation and intracellular distribution of SMAD2/3. Selective inhibition of TGFbr2/ALK5 signaling in microglia via intracerebral liposome-encapsulated SB-431542 delivery triggered hemorrhages after tMCAO, demonstrating that TGFβ1/TGFbr2/ALK5 signaling in microglia protects from hemorrhages. Consistent with observations in neonatal rats, depletion of microglia before tMCAO in P9 Cx3cr1(GFP/+)/Ccr2(RFP/+) mice exacerbated injury and induced hemorrhages at 24 h. The effects were independent of infiltration of Ccr2(RFP/+) monocytes into injured regions. Cumulatively, in two species, we show that microglial cells protect neonatal brain from hemorrhage after acute ischemic stroke. SIGNIFICANCE STATEMENT The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. We assessed whether microglial cells preserve neurovascular integrity after neonatal stroke. In neonatal rats, microglial depletion or pharmacological inhibition of TGFbr2/ALK5 signaling in microglia triggered hemorrhages in injured regions. The effect was not associated with additional changes in expression or intracellular redistribution of several tight junction proteins or collagen IV degradation induced by stroke. Consistent with observations in neonatal rats, microglial depletion in neonatal mice exacerbated stroke injury and induced hemorrhages. The effects were independent of infiltration of monocytes into injured regions. Thus, microglia protect neonatal brain from ischemia-induced hemorrhages, and this effect is consistent across two species.

Comparison of IgG concentrations by radial immunodiffusion, electrophoretic gamma globulin concentrations and total globulins in neonatal foals

REASONS FOR PERFORMING STUDY: Failure of transfer of passive immunity (FTPI) in foals is associated with a risk of infection and death. The current diagnostic gold standard is quantification of immunoglobulins using radial immunodiffusion (IgG-RID). Routine diagnosis is often performed using semi-quantitative tests. Concentrations of serum electrophoretic gamma globulins (EGG) and total globulins may be useful to assess FTPI, but few studies have investigated their use. OBJECTIVES: To assess agreement between IgG-RID and EGG, and evaluate the accuracy of total globulin concentration to diagnose FTPI based on both IgG-RID and EGG. STUDY DESIGN: Prospective study. METHODS: 360 serum samples were harvested at 6-24 hours post natum from 60 German Warmblood foals. Concentrations of EGG, IgG-RID and total globulin concentration (calculated from total proteins and albumin) were measured. Agreement between EGG and IgG-RID was assessed using Bland-Altman plots and Passing-Bablok regression. The accuracy of total globulin concentration was assessed using rank correlation and ROC curve analysis. RESULTS: Good agreement was found with slightly lower EGG than IgG-RID concentrations (Bland-Altman systemic bias, -1.9 g/L) which was more pronounced at higher concentrations (regression equation: IgG-RID = -0.78 +1.28xEGG). Correlations between total globulin concentration and EGG, and total globulin concentration and IgG-RID were 0.93 and 0.79, respectively. The area under the curve was 0.982 and 0.952 for EGG <4 g/L and <8 g/L, and 0.953 and 0.899 for IgG-RID <4 g/L and <8 g/L. Sensitivities and specificities of total globulin concentration in the diagnosis of FTPI were comparable to commonly used screening tests, but cut-offs could be selected to achieve sensitivities of >95% with 71.2% (IgG-RID) and 90.5% (EGG) specificity for <4 g/L, and >90% with 66.0% (IgG-RID) and 87.9% (EGG) specificity for <8 g/L. CONCLUSIONS: There is good agreement between EGG and IgG-RID, with slightly more conservative estimates of immunoglobulins obtained using EGG. Total globulins may be a useful and economic quantitative screening test with cut-offs achieving high sensitivities, but analyser-specific cut-offs may be necessary.
