Design of a system to implement occupational stress studies trough wearables devices and assessment tests

[Abstract] Introduction: Stress at work is a factor that has repercussions on both a personal and health level, as well as on productivity at work. Objective: To establish if the wearables are devices capable of determining the level of labor stress of working people in a research center. Methodology: This pilot study followed up different variables during 6 months on 11 participants of a research center. In the study, wearables Xiaomi MiB and 3 were used, which recorded and continuously monitored the physical activity and sleep of the participants. On the other hand, different specific evaluation tests were used to measure work stress, quality of life and sleep quality. Results: The data obtained from the tests and the wearables show that men feel slightly more stressed and sleep worse than women; however, men spend more time sitting and walking than women. Conclusions: It is considered important to replicate the study in larger and more heterogeneous cohorts

Combinando mapas de papel e smartphones na exploração do património cultural

UID/SOC/04647/2013Os mais recentes avanços tecnológicos permitiram o rápido crescimento de dispositivos capazes de Realidade Aumentada (RA). Estes poderão ser a chave para uma nova experiência de exploração do património cultural e histórico, actualmente muito dependente de informação estática ou aplicações móveis que podem não proporcionar uma visão contextualizada aos seus utilizadores. Neste artigo, exploramos novas formas de interacção com os tradicionais mapas de papel turísticos, através de mecanismos de Realidade Aumentada, mostrando informação contextual associada a locais culturais e históricos. Combinando um mapa de papel com um smartphone, o utilizador pode ver representações virtuais de elementos culturais, manipulá-los em 3D, sobrepor cartografia histórica, ver informação multimédia relevante, entre outros. Também analisamos reacções e feedback obtido de um teste preliminar de utilizadores, onde comparámos a nossa abordagem a uma baseada num mapa digital.publishersversionpublishe

Suporte interpares na doença mental

Background Peer support is a mutual aid system based on the belief that someone who faced/overcome adversity can provide support, encouragement and guidance to those who experience similar situations. Objective To conduct a systematic review that describes this concept and characterizes peer supporters, its practice and efficacy. Method Research on ISI Web of Science, EBSCO Psychology and Behavioral Sciences Collection and Medline databases (from 2001 to December 2013) was conducted using as keywords “mental illness”, “mental health”, “psychiatric disability”, “mental health services”, combined with “peer support”, “mutual support”, “self-help groups”, “consumers as providers”, “peer-run services”, “peer-run programs” and “social support”. Results We found 1,566 articles and the application of both the exclusion (studies with children, teenagers and elderly people; disease in comorbidity; peer support associated to physical illnesses or family members/caregivers) and the inclusion criteria (full text scientific papers, peer support or similar groups directed for schizophrenia, depression, bipolar or psychotic disorders) lead to 165 documents, where 22 were excluded due to repetition and 31 to incomplete text. We analyzed 112 documents, identifying as main peer support categories: characterization, peer supporter, practices and efficacy. Discussion Despite an increasing interest about this topic, there is no consensus, suggesting realizing more studies.Contexto O suporte interpares é um sistema de ajuda mútua baseado na crença de que alguém que enfrentou/superou adversidades pode oferecer apoio, encorajamento e orientação a outros que enfrentam situações similares. Objetivo Realizar uma revisão sistemática que caracterize o suporte interpares como prática, analise a sua eficácia e caracterize os pares prestadores de suporte interpares. Método Pesquisa nas bases de dados ISI Web of Science, EBSCO Psychology and Behavioral Sciences Collection e Medline (2001 a dezembro de 2013), utilizando as palavras-chave “mental illness”, “mental health”, “psychiatric disability”, “mental health services”, combinadas com “peer support”, “mutual support”, “self-help groups”, “consumers as providers”, “peer-run services”, “peer-run programs” e “social support”. Resultados Encontraram-se 1.566 artigos e foram aplicados os critérios de exclusão (artigos com crianças, adolescentes e idosos; doença mental em comorbidade; suporte interpares em doenças físicas ou familiares/cuidadores) e de inclusão (revistas científicas com texto integral disponível; suporte interpares ou grupos similares dirigidos a esquizofrenia, depressão, transtorno bipolar e outras perturbações psicóticas), resultando em 165 documentos. Excluíram-se 22 por repetição e 31 por texto incompleto, resultando em 112, os quais se identificaram como principais categorias do suporte interpares: caracterização, prestador de suporte, práticas e eficácia. Conclusão Existe interesse crescente pelo tema, embora alguns domínios não sejam consensuais, sugerindo necessidade de mais estudos

Low-cost GNSS technology for monitoring grazing sheep

Extensive livestock production is supported by natural and biodiverse pastures, characterized by marked seasonal variation of biomass, plant species and growth stage. The use of the food resources and the occupation of grazing space can be very heterogeneous in such conditions due to ruminants grazing behaviour. Successful grazing and pasture management requires an understanding of the adjustment mechanisms behind the grazing behaviour that enables adaptation to grazing conditions. Use of GNSS technology allows a quick and effective grazing data collection which is, however expensive, limiting its application to research purposes. This paper reviews the principles for the application of GNSS technology and evaluates the use of inexpensive commercial GNSS receivers (commercial of the shelf - COTS: CatTrackTM”). Six receivers were used for six data collection period over two months of continuous grazing on a natural pasture. The measured static and dynamic accuracy of the receivers is 14m and 40m, respectively. The precision was 3m and the reliability 80%. The tested equipment allows the differentiation between animal activities (grazing, resting and transit). It also determines sheep locations, allowing the characterization of patterns, pathways and preferred areas. It is concluded that the COTS equipment has a high quality / price ratio, so it can become an important support decision tool essential to a more precise pasture management

Thrombus aspiration in patients with ST-elevation myocardial infarction: results of a national registry of interventional cardiology

BACKGROUND: We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. METHODS: We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). RESULTS: We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). CONCLUSIONS: The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI..info:eu-repo/semantics/publishedVersio

estudos artísticos

A revista de estudos artísticos GAMA encontra, neste terceiro número, um caminho mais definido dentro do projeto global da comunicação de artistas sobre as obras de outros artistas. A Revista GAMA percorre tradições, registos, ações e intervenções artísticas, que assinalaram diversos momentos, com diferentes graus de difusão. Visa-se resgatar, recuperar a arte: é voltar a olhar, pelo escopo particular de um artista, a intervenção de um outro artista, com algum tempo de intervalo entre ambos. Este intervalo é um tempo de sedimentação, de filtragem, ou de recuperação de valores quase esquecidos. O tempo pode fornecer um ponto de vista privilegiado que permite novas interpretações, valorizações, interligações. Permite-se a reativação, o restauro: restauro não no sentido material, mas no sentido da reapresentação do conteúdo possibilitando reforçar um “museu imaginário,” livre de fronteiras e de hierarquias estabelecidas (Malraux). Os objetos de arte anteriores podem ter originado, ou vir a originar, novas obras, na sequência imprevisível dos discursos humanos mais significativos, reagrupando-se em termos de “ação” ou de “orientação,” de “imagem” ou de “palavra,” (Warburg) permitindo “restituir ao discurso o caráter de acontecimento” (Foucault). Entre a história e a memória, o arquivo e a deriva, a viagem e a identidade, a permanência e a resistência, a Revista GAMA vem assinalando um percurso de salvaguarda, de marcação de registos, de preservação de uma riqueza, ora material ora conceptual: a arte detém-se e debruça-se sobre as suas marcas, os seus projetos, os seus registos, as suas transições.

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
