O enfermeiro no cuidado à vítima de trauma com dor: o quinto sinal vital

Estudo qualitativo que avaliou o conhecimento do enfermeiro acerca da dor na vítima de trauma. Desenvolvido em um hospital público, por meio da aplicação de questionário e teste de conhecimento e tratados pela Análise de Conteúdo. A amostra compreendeu 27 enfermeiros, em sua quase totalidade de mulheres (92,6%), idade média 31 ±10,3 anos e maioria com formação inferior a 1 ano (51,8%). Os resultados evidenciaram a dor como sensação desagradável, sinal de alerta e uma experiência subjetiva. A avaliação da dor é vista por aspectos subjetivos e objetivos. A maioria (59,3%) desconhece os instrumentos de avaliação e dentre os que conhecem a escala numérica foi a mais referida. As estratégias de controle de dor mencionadas foram medidas em farmacológicas, não farmacológicas e combinadas. Todos os enfermeiros consideraram a avaliação da dor importante e um caminho para o tratamento humanizado e qualificado, que orienta a conduta terapêutica e restabelece o bem-estar do paciente.

Capacity to within one bit of a class of Gaussian multicast channels with interference

This paper studies the fundamental operational limits of a class of Gaussian multicast channels with an interference setting. In particular, the paper considers two base stations multicasting separate messages to distinct sets of users. In the presence of channel state information at the transmitters and at the respective receivers, the capacity region of the Gaussian multicast channel with interference is characterized to within one bit. At the crux of this result is an extension to the multicast channel with interference of the Han-Kobayashi or the Chong-Motani-Garg achievable region for the interference channel.

Asymptotic capacity of static multiuser channels with an unknown number of users

We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel capacity and spectral efficiency in the large-system limit.

Work capacity evaluation among nursing aides

Work force aging generates the need to develop studied with the purpose to evaluate work capacity. The objective of this study was to analyze the work capacity of the nursing aides of a public health institute. A cross-sectional study was developed on the work capacity of these professionals regarding their demographic, work and lifestyle characteristics (n=241). A univariate logistic regression analysis was performed with inadequate work capacity (score below 37) as the dependent variable. There was an association with age (the eldest), work time at the institution (the oldest), body mass index (obesity) and item 1 of the work capacities index: present work capacity. This information can be used to create preventive measures and restore work capacity.

Nonshivering thermogenesis capacity associated to mitochondrial DNA haplotypes and gender in the greater white-toothed shrew, Crocidura russula.

A selection gradient was recently suggested as one possible cause for a clinal distribution of mitochondrial DNA (mtDNA) haplotypes along an altitudinal transect in the greater white-toothed shrew, Crocidura russula (Ehinger et al. 2002). One mtDNA haplotype (H1) rare in lowland, became widespread when approaching the altitudinal margin of the distribution. As H1 differs from the main lowland haplotype by several nonsynonymous mutations (including on ATP6), and as mitochondria play a crucial role in metabolism and thermogenesis, distribution patterns might stem from differences in the thermogenic capacity of different mtDNA haplotypes. In order to test this hypothesis, we measured the nonshivering thermogenesis (NST) associated with different mtDNA haplotypes. Sixty-two shrews, half of which had the H1 haplotype, were acclimated in November at semioutdoor conditions and measured for NST throughout winter. Our results showed the crucial role of NST for winter survival in C. russula. The individuals that survived winter displayed a higher significant increase in NST during acclimation, associated with a significant gain in body mass, presumably from brown fat accumulation. The NST capacity (ratio of NST to basal metabolic rate) was exceptionally high for such a small species. NST was significantly affected by a gender x haplotype interaction after winter-acclimation: females bearing the H1 haplotype displayed a better thermogenesis at the onset of the breeding season, while the reverse was true for males. Altogether, our results suggest a sexually antagonistic cyto-nuclear selection on thermogenesis.
