- Saúde Ocupacional aplicada à DançaPublication . Santos, Mónica; Almeida, Armando; Lopes, CatarinaIntrodução/ enquadramento/ objetivos O setor da Dança está pouco retratado em contexto de Saúde Ocupacional e a bibliografia é razoavelmente escassa. Neste setor o profissional pode apenas efetuar ensaios e atuações (a solo ou em equipa), pode dar aulas para eventuais futuros colegas e/ ou para leigos ou acumular ambas as vertentes. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em agosto de 2020 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo A dança é uma arte complexa, cujo instrumento é o corpo. Conjuga movimento com a emoção, servindo também como forma de comunicação. Em alguns estilos de dança a rotina de treinos é muito exigente e competitiva, de forma a aperfeiçoar departamentos como força, resistência, velocidade, flexibilidade, equilíbrio e controlo. Aos treinos intensos, por vezes, associam-se algias e lesões concretas. Por exemplo, no Ballet clássico, a exigência técnica é muito elevada e desafiante e, na bibliografia selecionada, é certamente a dança mais estudada neste contexto. A escassa bibliografia encontrada incide sobretudo nas principais lesões associadas (quer acidentes de trabalho, quer doenças profissionais); sendo que alguns artigos também destacam o eventual consumo de substâncias psicoativas em algumas modalidades específicas. Discussão e Conclusões Os autores elaboraram uma descrição dos principais Fatores de Risco/ Riscos Laborais deste setor, no geral; bem como listaram as Medidas de Proteção (coletivas e individuais) que consideram ser mais adequadas. O setor da dança está muito pouco estudado pela Saúde Ocupacional, sendo pertinente a análise da realidade portuguesa, sobretudo em alguns estilos muito desenvolvidos no nosso país e sobre os quais não se encontrou qualquer bibliografia específica (mesmo em contexto internacional).
- Brief report on double-chamber syringes patents and implications for infusion therapy safety and efficiencyPublication . Sousa, Liliana B.; Santos-Costa, Paulo; Marques, Inês A.; Cruz, Arménio; Salgueiro-Oliveira, Anabela; Parreira, PedroThis review aimed to map the existing patents of double-chamber syringes that can be used for intravenous drug administration and catheter flush. A search was conducted in the Google patents database for records published prior to 28 October 2020, using several search terms related to double-chamber syringes (DCS). Study eligibility and data extraction were performed by two independent reviewers. Of the initial 26,110 patents found, 24 were included in this review. The 24 DCS that were found display two or more independent chambers that allow for the administration of multiple solutions. While some of the DCS have designated one of the chambers as the flushing chamber, most patents only allow for the sequential use of the flushing chamber after intravenous drug administration. Most DCS were developed for drug reconstitution, usually with a freeze-dried drug in one chamber. Some patents were designed for safety purposes, with a parallel post-injection safety sheath chamber for enclosing a sharpened needle tip. None of the DCS found allow for a preand post-intravenous drug administration flush. Given the current standards of care in infusion therapy, future devices must allow for the sequential use of the flushing chamber to promote a pre-administration patency assessment and a post-administration device flush.
- How good are RGB cameras retrieving colors of natural scenes and paintings? — a study based on hyperspectral imagingPublication . Linhares, João M. M.; Monteiro, José A. R.; Bailão, Ana; Cardeira, Liliana; Kondo, Taisei; Nakauchi, Shigeki; Picollo, Marcello; Cucci, Costanza; Casini, Andrea; Stefani, Lorenzo; Nascimento, Sérgio Miguel CardosoRGB digital cameras (RGB) compress the spectral information into a trichromatic system capable of approximately representing the actual colors of objects. Although RGB digital cameras follow the same compression philosophy as the human eye (OBS), the spectral sensitivity is different. To what extent they provide the same chromatic experiences is still an open question, especially with complex images. We addressed this question by comparing the actual colors derived from spectral imaging with those obtained with RGB cameras. The data from hyperspectral imaging of 50 natural scenes and 89 paintings was used to estimate the chromatic differences between OBS and RGB. The corresponding color errors were estimated and analyzed in the color spaces CIELAB (using the color difference formulas ∆E* ab and CIEDE2000), Jzazbz, and iCAM06. In CIELAB the most frequent error (using ∆E* ab) found was 5 for both paintings and natural scenes, a similarity that held for the other spaces tested. In addition, the distribution of errors across the color space shows that the errors are small in the achromatic region and increase with saturation. Overall, the results indicate that the chromatic errors estimated are close to the acceptance error and therefore RGB digital cameras are able to produce quite realistic colors of complex scenarios.
- “Follow the whistle: physical activity is calling you”: evaluation of implementation and impact of a Portuguese nationwide mass media campaign to promote physical activityPublication . Silva, Marlene Nunes; Godinho, Cristina; Salavisa, Marta; Owen, Katherine; Santos, Rute; Silva, Catarina Santos; Mendes, Romeu; Teixeira, Pedro J.; Freitas, Graça; Bauman, AdrianTo raise perceived capability (C), opportunity (O) and motivation (M) for physical activity (PA) behaviour (B) among adults, the Portuguese Directorate-General of Health developed a mass media campaign named “Follow the Whistle”, based on behaviour change theory and social marketing principles. Comprehensive formative and process evaluation suggests this media-led campaign used best-practice principles. The campaign adopted a population-wide approach, had clear behavioural goals, and clear multi-strategy implementation. We assessed campaign awareness and initial impact using pre (n = 878, 57% women) and post-campaign (n = 1319, 58% women) independent adult population samples via an online questionnaire, comprising socio-demographic factors, campaign awareness and recall, and psychosocial and behavioural measures linked to the COM-B model. PA was assessed with IPAQ and the Activity Choice Index. The post-campaign recall was typical of levels following national campaigns (24%). Post-campaign measures were higher for key theory-based targets (all p < 0.05), namely self-efficacy, perceived opportunities to be more active and intrinsic motivation. The impact on social norms and self-efficacy was moderated by campaign awareness. Concerning PA, effects were found for vigorous activity (p < 0.01), but not for incidental activity. Overall the campaign impacted key theory-based intermediate outcomes, but did not influence incidental activity, which highlights the need for sustained and repeated campaign efforts.
