ABSTRACT Introduction: Urgent blood component transfusions may be life-saving for patients in hemorrhagic shock. Measures to reduce the time taken to provide these transfusions, such as uncrossmatched transfusion or abbreviated testing, are available. However, transport time is still an additional delay and the use of a pneumatic tube system (PTS) may be an alternative to shorten the transport time of blood components. Objectives: To assess pneumatic tube system transportation of blood components based on a validation protocol. Methods: Pre- and post-transport quality control laboratory parameters, visual appearance, transport time and temperature of the packed red blood cells (RBCs), thawed fresh plasma (TFP), cryoprecipitate (CR), and platelet concentrate (PC) were evaluated. Parameters were compared between transport via pneumatic tube and courier. Results: A total of 23 units of RBCs, 50 units of TFP, 30 units of CR and ten units of PC were evaluated. No statistically significant differences were found between pre- and post-transport laboratory results. There was also no difference in laboratory parameters between transport modalities (PTS versus courier). All blood components transported matched regulatory requirements for quality criteria. The temperature during transport remained stable and the transport time via PTS was significantly shorter than the courier’s transport time (p < 0.05). Conclusion: The PTS was considered a fast, safe and reliable means of transportation for blood components, also securing quality prerequisites.

ABSTRACT Introduction: As a result of the coronavirus pandemic, many students are worried that they may lose their academic term. Objective: Validate a scale to measure the perception of possible academic impacts among Peruvian university students. Method: A validation process was conducted of a test measuring the perception of university students about possible academic impacts. The validation was based on a scientific bibliography search, development of a preliminary overview, validation of the test by 59 experts: epidemiologists, researchers and physicians, exploratory factor analysis, and statistical analysis. Results: In terms of relevance, item 7 was found to be more essential or important than the others (V = 1.00; CI 95 %: 0.73-0.96). Item 8 (M = 3.80; /= 1.152) exhibits the highest mean, and item 6 the lowest (M = 3.03; SD = 1.342). AFE relevance is justified by the KMO index (0.85) and Bartlett's test (12577.0; gl = 28; p = / 0.001), both of which were found to be acceptable and significant. A Cronbach's α coefficient of 0.899 was obtained, with a confidence interval of 95%, SD 0.882-0.898, indicating a good consistency level. Conclusions: A single factor scale was validated which measures the perception of university students about the possible impacts of the coronavirus pandemic on their studies. It is necessary to evaluate each reality, and the tool may serve as a base scale for that purpose.

RESUMEN Introducción: La pandemia del coronavirus ha generado que muchos estudiantes teman perder el ciclo. Objetivo: Validar una escala que mida la percepción de posibles repercusiones académicas en estudiantes universitarios en el Perú. Metodología: Se realizó un proceso de validación de un test que mide la percepción acerca de las posibles repercusiones académicas en estudiantes universitarios. La validación se realizó mediante búsqueda de literatura científica, construcción del primer bosquejo, validación del test por expertos (59 expertos: epidemiólogos, investigadores, médicos), análisis factorial exploratorio y estadístico. Resultados: Respecto a la relevancia se observa que el ítem 7 es más esencial o importante que los demás (V = 1,00; IC 95 %: 0,73-0,96). El ítem 8 (M = 3,80; /= 1,152) presenta la mayor media y, la más baja, el ítem 6 (M = 3,03; DE = 1,342). La pertinencia del AFE se justifica con el índice KMO (0,85) y la prueba de Bartlett (12577,0; gl = 28; p = / 0,001) siendo aceptables y significativos. Se obtuvo un coeficiente α de Cronbach de 0,899 con un intervalo de confianza del 95 % de 0,882-0,898; indicando que la consistencia del instrumento es buena. Conclusiones: Se validó una escala de factor único que mide la percepción que tienen los estudiantes universitarios acerca de las posibles repercusiones de la pandemia del coronavirus en sus estudios. Es necesario evaluar cada realidad y el instrumento puede servir como una escala base para ello.

Resumo O presente trabalho recorre à fenomenologia semiótica para analisar diários pessoais em blogs com o objetivo de definir e verificar suas potencialidades como movimento contínuo e sustentado para mudanças pessoais e autoinovação. A análise justapõe, por métodos quanti e qualitativos, dados cronológicos e linguísticos de textos autorreferenciados (semiótica) com o sentido de conversas internas reveladas em discurso (fenomenologia). Foi tomado um domínio específico para postagens aleatórias de blogueiros que apresentassem termos autorreferentes, como "eu sinto" "eu penso", "eu acredito", "minha vida" etc. A partir disso, foram selecionadas postagens com autodescrições densas e díspares de pensamentos e sentimentos pessoais. Foram analisadas, aproximadamente, 150 postagens heterogêneas das quais retirou-se 12 postagens homogêneas, sendo 9 escritas por mulheres e 3 por homens, todos falantes nativos da língua inglesa. Concluiu-se que o texto de blog pessoal enseja bem-estar psicológico por meio de autoclarificações dialógicas, além de facilitar a emergência de novas perspectivas ou autoatualização podendo, assim, conduzir à autoinovação.

Abstract This work is a semiotic phenomenological approach of writing in personal journal blogs to define and verify their potential as continuous and sustained movement toward personal change or self-innovation. The analysis juxtaposes, by quantitative and qualitative methods, chronological self-referential text data (semiotics) with the meaning of internal conversation disclosed in discourse (phenomenology). We take a specific blog domain for posts from random bloggers that would present self-referent terms as "I feel", "I think", "I believe", "my life", etc. Then we selected those posts with dense self-descriptions and expression of disparate personal thoughts and feelings. Approximately 150 posts were analyzed, resulting in a final sample of 12 homogeneous posts from a heterogeneous group of bloggers, nine females and three males, all native English speakers. We conclude that personal blog texts help convey psychological well-being through dialogical self-clarification, facilitate the emergence of new perspectives or self-actualizing, and can lead to self-innovation.

O consumo de álcool na adolescência é um fenômeno multideterminado, sendo que nele as relações familiares têm um papel destacado, tanto como fator protetor quanto como de risco. As adolescentes têm mudado seu padrão de consumo e aos poucos vem igualando ao dos meninos. Foi realizado levantamento bibliográfico na base Web of Science, entre 2006-2011, com os descritores girls, alcohol, family, com o objetivo de apresentar uma revisão sistemática do tema. Exibem-se dados bibliométricos, que indicam uma tendência de crescimento da produção científica nos últimos anos. Aprofundam-se os resultados em uma análise qualitativa, destacando-se o papel que a proximidade emocional com os pais e o monitoramento parental exercem enquanto fatores de proteção para as adolescentes.

Alcohol consumption by teenagers is a multi-determined phenomenon. Family relations play a prominent role in it and can be both a protection and a risk factor. Teenager girls have been changing their consumption pattern, becoming more and more similar to boys'. A bibliographic survey was carried out at Web of Science database, from 2006 to 2011, with the descriptors girls, alcohol and family, aiming to present a systematic review of the topic. Bibliometric data are shown, indicating a trend of growth in scientific production in the last years. The results are deepened through qualitative analyses of some articles. The role of emotional proximity with parents and parental monitoring is highlighted as protection factors for girls.

O presente estudo teve por objetivo identificar quais os projetos que pais e mães manifestam ter para seus filhos, assim como as estratégias que utilizam no processo educativo a fim de concretizá-los. Foram entrevistados, em suas residências, oito casais que coabitavam, de nível socioeconômico-cultural médio, com pelo menos um filho em idade escolar, residentes em Porto Alegre. A partir da análise de conteúdo das entrevistas, foi possível constatar projetos tais como: formação profissional, formação pessoal e constituir família. Também se encontrou uma categoria de respostas a qual denominamos de liberdade para que os filhos construam seus próprios projetos. Quanto às estratégias para concretizar tais projetos, identificou-se: investimento na formação profissional, em conforto, diálogo, cuidado, tratamento igualitário entre os filhos, respeito pelos interesses dos filhos e instrumentalização pedagógica. Os entrevistados evidenciaram a valorização da formação profissional de seus filhos. Todos os pais e mães entrevistados prospectam seus filhos numa vida adulta.

This study aimed to identify fathers and mothers' desired projects related to their children, and strategies used to achieve them in the educative process. Eight couples, with an average social-economic-cultural level, were home interviewed. They had at least one school age child and lived at Porto Alegre. Interview content analysis made possible to identify projects such as: professional training, personal development, family constitution. It was also possible to identify a category of answers that was called freedom for the children to build their own projects. Professional training investment, comfort investment, dialogue, care, egalitarian treatment between children, respect by children's interests and pedagogical instrumentalization were perceived as strategies used by these parents to achieve their projects. Professional training was seen by the participants as highly worth it. All parents interviewed prospect their children in an adult life.

Falhas de memória são comuns no cotidiano. Contudo, elas podem indicar ocorrências de problemas cognitivos, principalmente entre idosos. O artigo traz a tradução e a adaptação do Prospective and Retrospective Memory Questionnaire (PRMQ). O instrumento, no original constituído de 16 itens, avalia auto-relatos de falhas de memória prospectiva e retrospectiva. O estudo contou com 642 participantes, com idade variando entre 16 e 81 anos, recrutados em uma universidade e em grupos comunitários. A análise fatorial exploratória dos dados do PRMQ apontou a validade de construto apenas para oito itens. Então, optou-se por reconsiderar mais dois itens que apresentaram carga fatorial aceitável e compor uma escala de 10 itens, sendo cinco para cada dimensão da memória. A correlação para validade convergente e discriminante foi realizada com o Questionário de Percepção Subjetiva de Queixas de Memória para idosos (MAC-Q), em uma amostra de 38 participantes idosos, com idade média de 69 anos. O PRMQ-10 apresentou validade e confiabilidade (a = 0,80), com boas perspectivas para uso em pesquisa.

Memory failures are common in daily life. However, these failures could indicate cognitive problems, mainly in elders. This study presents the translation and adaptation of the Prospective and Retrospective Memory Questionnaire (PRMQ) to Portuguese. The questionnaire measures prospective and retrospective self-report memory failures through 16 items. There were 642 participants aged between 16 and 81 years recruited in a university and in community groups. The exploratory factor analysis revealed the construct validity only for eight items. So, it was reconsidered two of the original 16 items that showed acceptable factorial load and tested a questionnaire of 10 items. Convergent and concurrent validity was tested in a sample of 38 participants aged around 69 years, through the Elders' Subjective Perception of Memory Complaints Questionnaire (MAC-Q). As a result the reduced PRMQ with 10 items showed both validity and confidence (a = 0,80). At this point the questionnaire seems promising for research using.
