Percepción del dolor en pacientes postoperados de cirugía cardiaca

Pain is defined as an unpleasant sensory or emotional experience, associated with tissue damage, that is a reality linked to the surgical procedure and the postoperative period. Objective: Knowing the degree of pain experienced by patients after cardiac surgery, depending on the type of intervention they underwent, over the post-operative period in an intensive care unit (ICU). Method: Descriptive observational study. Pain was assessed by the visual analog scale (VAS), going from 0 to 10, thereby obtaining the first VAS1 assessment at 2 h post-extubation and every 8 hours thereafter up to 48 hours or until discharge to floor VAS7. It included patients having undergone cardiac surgery [valve surgery, bypass, combined procedure (including valve surgery and bypass) and mediastinitis]. Data were processed using Spss.v 20. Results: 120 patients 70 years old on average (standard deviation (SD): 13.3 years old) were included, out of which 70% were male. 40.8% of them had underwent bypass coronary revascularization. Patients subjected to the bypass technique showed an VAS1 mean value of 4.35 (SD: 2.45), unlike those subjected to valve surgery, who showed a mean value of 2.89 (SD: 2.27), those subjected to the combined procedure, who showed a mean value of 3.87 (SD: 2.90), and those with mediastinitis, who showed a mean value of 3.33 (SD: 3.51); (p < 0.031). 28.5% of patients had underwent revascularization (n = 49 ) by an internal mam mary artery (IMA) graft. These patients showed a mean value for VAS1 of 5.4 (SD: 1.89), unlike those who had underwent a combined procedure [IMA and saphenous vein (SV)], who showed a mean value of 3.9 (SD: 2.6), and those who had underwent a SV procedure , who showed a mean value of 3.5 (SD: 2.1); (p < 0.045). Conclusions: Patients having underwent bypass and IMA procedures perceive more pain than in other cardiac surgery and graft interventions

Confirmatory factor analysis of an inventory of perception of insecurity and fear of crime

This paper focuses on the study of the factorial structure of an inventory to estimate the subjective perception of insecurity and fear of crime. Made from the review of the literature on the subject and the results obtained in previous works, this factor structure shows that this attitude towards insecurity and fear of crime is identified through a number of latent factors which are schematically summarized in (a) personal safety, (b) the perception of personal and social control, (c) the presence of threatening people or situations, (d) the processes of identity and space appropriation, (e) satisfaction with the environment, and (f) the environmental and the use of space. Such factors are relevant dimensions to analyze the phenomenon. Method: A sample of 571 participants in a neighborhood of Barcelona was evaluated with the proposed inventory, which yielded data from the distributions of all the items provided. The administration was conducted by researchers specially trained for it and the results were analyzed by using standard procedures in the confirmatory factor analysis (CFA) from the hypothesized theoretical structure. The analysis was performed by decatypes according to the different response scales prepared in the inventory and their ordinal nature, and by estimating the polychoric correlation coefficients. The results show an acceptable fit of the proposed model, an appropriate behavior of the residuals and statistically significant estimates of the factor loadings. This would indicate the goodness of the proposed factor structure.

New technologies and nursing: use and perception of primary healthcare nurses about electronic health record in Catalonia, Spain

This study was aimed to analyze and assess the use and perception of electronic health records (EHRs) by nurses. The study sample included 113 nurses from different shifts of primary health facilities in Catalonia, Spain, devoted to adult as well as pediatric outpatients using EHRs throughout the year 2010. A majority of the sample (87.5%) were women and 12.5% were men. The average age was 44.27 years and the average time working in primary healthcare was 47.15 months. A majority (80.4%) received specific training on the use of the EHR and 19.6% did not. The use of the application required side technical support (mean: 3.42) and it is considered necessary to learn more about the performance of the application (mean: 3.50). The relationship between the average ratings that nurses have about the EHR and age shows that there is no statistically significant linear relationship (r = - 0.002, p-value = 0.984). As to how long they have used the EHRs, there are significant differences (r= -0.304, p-value = 0.00), so the more time the nurse takes using the EHR, the greater degree of satisfaction is shown. In addition, there are significant differences between nurses" perceptions regarding the EHR and gender (t = - 0.421, p-value = 0.675). Nurses assessed as positive the contribution of the EHRs in their nursing care day work (average score: 2.55/5). Considering that the usability of the EHR device is assessed as satisfactory, the results of the perception of nurses show that we must also take into account the training and emphasize the need for a side technical support in the implementation process of the EHR. Doing so, the positive perception that nurses have in regard to information and communication technology in general and with respect to the EHR in particular may be increased.

Identidad, percepción de vitalidad etnolingüística y comunicación intergrupal en Cataluña: An identity and ethnolinguistic perception vitality study in Catalonia

Catalan has drawn considerable attention given its impressive institutional support and increased usage since the restoration of the Generalitat of Catalonia. We report a study on 112 Catalan-speaking students who were administered the"subjective vitality questionnaire". Results show (and these are compared with reports 20 years ago) that it continues to gain momentum and status, even with the International stature of Spanish. The theoretical and pragmatic significance of these findings are discussed in terms of vitality"s role in shaping Language choices (Catalan vs. Castilian) in everyday communication as well as the societal level in forging Language policies for communicating in Catalan in business, political, educational, and media arenas

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioural response dynamics to pheromone in Drosophila

Background: Insects respond to the spatial and temporal dynamics of a pheromone plume, which implies not only a strong response to"odor on", but also to"odor off". This requires mechanisms geared toward a fast signal termination. Several mechanisms may contribute to signal termination, among which odorant-degrading enzymes. These enzymes putatively play a role in signal dynamics by a rapid inactivation of odorants in the vicinity of the sensory receptors, although direct in vivo experimental evidences are lacking. Here we verified the role of an extracellular carboxylesterase, esterase-6 (Est-6), in the sensory physiological and behavioral dynamics of Drosophila melanogaster response to its pheromone, cis-vaccenyl acetate (cVA). Est-6 was previously linked to post-mating effects in the reproductive system of females. As Est-6 is also known to hydrolyze cVA in vitro and is expressed in the main olfactory organ, the antenna, we tested here its role in olfaction as a putative odorant-degrading enzyme. Results: We first confirm that Est-6 is highly expressed in olfactory sensilla, including cVA-sensitive sensilla, and we show that expression is likely associated with non-neuronal cells. Our electrophysiological approaches show that the dynamics of olfactory receptor neuron (ORN) responses is strongly influenced by Est-6, as in Est-6° null mutants (lacking the Est-6 gene) cVA-sensitive ORN showed increased firing rate and prolonged activity in response to cVA. Est-6° mutant males had a lower threshold of behavioral response to cVA, as revealed by the analysis of two cVAinduced behaviors. In particular, mutant males exhibited a strong decrease of male-male courtship, in association with a delay in courtship initiation. Conclusions: Our study presents evidence that Est-6 plays a role in the physiological and behavioral dynamics of sex pheromone response in Drosophila males and supports a role of Est-6 as an odorant-degrading enzyme (ODE) in male antennae. Our results also expand the role of Est-6 in Drosophila biology, from reproduction to olfaction, and highlight the role of ODEs in insect olfaction. Keywords: carboxylesterase, esterase 6, olfaction, pheromone, signal termination

Risk perception and stages of smoking acquisition = Percepción de riesgo y etapas de iniciación en el consumo de tabaco

The purpose of this descriptive survey was to investigate the risk perceptions of smoking in a sample of 1,510 Spanish adolescents(49.1% males; mean age = 14.03; SD = 1.28). In addition, the present research categorised adolescents into one of the fourstages of smoking acquisition, as described by the Transtheoretical Model of Change (TMC): Precontemplation (notthinking about trying smoking in the next 6 months), Contemplation (thinking about trying smoking in the next 6 months), Preparation (thinking about starting smoking in the next 30 days) and Action (smokers), by gender and age. The results showed that age and risk perceptions are important variables in the progression through the stages of change towards regular tobacco consumption (Action stage). These results clearly demonstrate the importance of starting antismoking campaigns at an early age to prevent smoking acquisition or the thought of starting in the near future. These findings also highlight the need to continuously remind adolescents about the negative consequences of smoking

Effect of reducing and replacing pork fat on the physicochemical, instrumental and sensory characteristics throughout storage time of small caliber non-acid fermented sausages with reduced sodium content

The effect of pork fat reduction (from 44% to 20% final fat content) and its partial substitution by sunflower oil (3% addition) on the physicochemical, instrumental and sensory properties throughout storage time of small caliber non-acid fermented sausages (fuet type) with reduced sodium content (with partial substitution of NaCl by KCl and K-lactate) and without direct addition of nitrate and nitrite (natural nitrate source used instead), was studied. Results showed that sausages with reduced fat (10% initial fat content) and with acceptable sensory characteristics can be obtained by adding to the shoulder lean (8% fat content) during the grinding, either 3.3% backfat (3% fat content) or 3% sunflower oil, both previously finely comminuted with lean. Furthermore, sunflower oil showed to be suitable for partial pork backfat substitution in very lean fermented sausages, conferring desirable sensory properties similar to those of sausages with standard fat content. The sensory quality of the sausages was maintained after three-month cold storage in modified atmosphere.

Un estudio transversal sobre la percepción de la vitalidad etnolingüística en jóvenes y adultos de Catalunya = A cross-sectional study on ethnolinguistic vitality perception in young and adulthood people from Catalonia

El estudio utiliza un diseño transversal en el campo de la percepción de la vitalidad etnolingüística. Es el primero que compara la percepción de la vitalidad etnolingüística, así como los factores asociados, entre adultos jóvenes y adultos, en relación con los grupos castellanohablantes y catalanohablantes de la Comunidad Autónoma de Cataluña. Para ello, se aplicó el 'Cuestionario de vitalidad etnolingüística subjetiva' (CVS) a una muestra de 527 participantes, 268 jóvenes y 259 adultos, de los cuales se seleccionó una submuestra de individuos que tenían el catalán como lengua materna y se identificaban como catalanes (n=301). En ambas muestras se aduce una tendencia a descriminar favorablemente la vitalidad percibida por el grupo catalán, aspecto que se acentúa significativa en el grupo de jóvenes estudiados en relación al grupo de edad de los adultos. Se discuten los resultados según las repercusiones teóricas y pragmáticas de los estudios realizados en el ámbito de la comunicación intergrupal
