A Violência no Local de Trabalho em Instituições de Saúde: Um Estudo Monocêntrico sobre Causas, Consequências e Estratégias de Prevenção
Introduction: Workplace violence is one of the main risk factors in the professional world. Healthcare workers are at higher risk when
compared to other sectors. Our study aimed to characterize physical and verbal violence in a public hospital and to define occupational
health prevention and surveillance strategies.
Material and Methods: Single center observational cross-sectional study, carried amongst healthcare workers in a public hospital in
Lisbon. A qualitative survey was carried out through six in-depth interviews. A quantitative survey was carried through questionnaires
delivered to 32 workers. A significance level of 5% was accepted in the assessment of statistical differences. The Mann-Whitney test
and the Fisher’s exact test were used to calculate p values.
Results: The main results are: (1) 41 violence incidents were reported in the quantitative phase; (2) 5/21 [23.81%] victims notified
the incident to the occupational health department; (3) 18/21 [85.71%] victims reported a permanent state of hypervigilance; (4) 22/28
[78.57%] participants self-reported poor or no familiarity with internal reporting procedures; (5) 24/28 [85.71%] participants believed it
is possible to minimize workplace violence.
Discussion: Workplace violence is favored by unrestricted access to working areas, absence of security guards and police officers
or scarce intervention. The low notification rate contributes to organizational lack of action. The state of hypervigilance reported in our
study reflects the negative effects of threatening occupational stressors on mental health.
Conclusion: Our results show that workplace violence is a relevant risk factor that significantly impacts workers’ health in a noxious
manner, deserving a tailored occupational health approach whose priority areas and strategies have been determined.Introdução: A violência no local de trabalho é um dos principais fatores de risco no mundo do trabalho. Os trabalhadores da saúde
apresentam um risco superior. O nosso estudo teve como objetivo caracterizar a violência física e verbal num hospital público e definir
estratégias de prevenção e vigilância em saúde ocupacional.
Material e Métodos: Estudo observacional transversal monocêntrico, conduzido num hospital público em Lisboa com trabalhadores
da saúde. Foi realizado um inquérito qualitativo com entrevistas em profundidade a seis trabalhadores e um inquérito quantitativo
com questionários a 32 trabalhadores. Aceitou-se um nível de significância de 5% na avaliação das diferenças estatísticas. O teste de
Mann-Whitney e o teste exato de Fisher foram usados para calcular os valores de p.
Resultados: Os principais resultados são: (1) 41 episódios reportados na fase quantitativa; (2) 5/21 [23,81%] vítimas notificaram o incidente; (3) 18/21 [85.71%] vítimas reportaram estados de hipervigilância permanente; (4) 22/28 [78,57%] participantes não conheciam
ou conheciam mal os procedimentos de notificação; (5) 24/28 [85,71%] consideravam possível minimizar o problema.
Discussão: A violência é favorecida pelo acesso livre às zonas de trabalho, ausência de agentes de segurança e polícia ou falta da
respetiva intervenção. A baixa notificação contribui para a ausência de medidas organizacionais. O estado de hipervigilância relatado
reflete o efeito prejudicial da exposição a fontes de stress e ameaça.
Conclusão: A violência no local de trabalho é um fator de risco relevante, com impacto negativo na saúde dos trabalhadores e merece
uma abordagem individualizada no âmbito da saúde ocupacional, cujas áreas e estratégias prioritárias foram definidas neste estudo.

Improving real estate CRM user experience and satisfaction: A user-centered design approach
Despite the growth in CRM installations, e-CRM projects still have a significant failure rate, even after substantial investments in CRM technology. High rates of failure mean that the current requirements for developing and designing CRM need to be analysed. It's not enough to just look at data related to a service's efficiency; it's also crucial to consider the impact on the user experience and their overall level of satisfaction. Given that CRM is a people-centric business strategy, it's pertinent to wonder how much progress may be made in a similarly people-centric field like Real Estate through the development and use of a user-centred design approach. This study aims to seamlessly integrate a mobile customer relationship management (m-CRM) system with an electronic customer relationship management (e-CRM) system to increase customer loyalty, satisfaction, and performance through a user-friendly interface. User research, preliminary interviews, five usability interviews, and satisfaction surveys confirmed the functionality implemented and for each iteration, an expert was used to evaluate it. For this artifact's creation and assessment, the DSR technique was used, with each interview serving as a data point for the model. It was determined that the Desktop interface solution may improve this CRM’s ease of use and user satisfaction, thereby benefiting the real estate industry through strengthened connections and more straightforward oversight of professionals' performances.info:eu-repo/semantics/publishedVersio
Impact of ActiGraph® cutoffs on time spent in moderate to vigorous physical activities in COPD
ActiGraphs® are often used to assess time in moderate to vigorous physical activities (MVPA) in people with COPD. Different cutoffs can be used to quantify MVPA. If they yield similar or different MVPA results is yet unknown. There are no cutoffs specifically developed, nor validated, for COPD, but Troiano and Freedson cutoffs are the most used. Recently, Santos-Lozano proposed a cutoff specific for older people, that has been used in COPD. This study aimed to explore MVPA results quantified with different cutoffs in COPD.
Participants wore the ActiGraph wGT3X for 7 days and data were included if they had used it for at least 8h (7am to 10pm) for 4 days (Choi algorithm for non-wear time). MVPA was estimated using the cutoffs from Troiano, Freedson and Santos-Lozano. Differences between cutoffs were explored with Friedman Test, followed by post-hoc comparisons.
107 people with COPD (79%♂; 68±8y; FEV1pp 49±17) were included. MVPA was affected by cutoffs (χ2(2)=194.56, p<0.001). Santos-Lozano cutoff yielded the highest MVPA estimates, followed by Freedson and Troiano cutoffs (median [Interquatile Range] = 57[30-90] vs 16[4-38] vs 8[2-22] (Fig.1). All cutoffs differed significantly from each other (p<0.001).
The cutoff selection affects MVPA estimates in people with COPD and may mislead the classification of these patients as physically (in)active. Future studies should develop MVPA cutoffs adapted to people with COPD.CENTR(AR): pulmões em andamento by Programa de Parcerias para o Impacto, Portugal Inovação Social through Programa Operacional Inclusão Social e Emprego (POISE-03-4639-FSE-000597).

Influence of human biology and health (hbh) teaching–learning process on students’ conceptions of the covid-19 vaccine
The COVID‐19 pandemic created the need for universal vaccination. This study aimed to
compare university students’ (pre‐service teachers) conceptions who had already learned the im‐
mune system and vaccination topics in the “Human Biology and Health (HBH)” curricular unit with
those who had not yet taken part in it. It also intended to verify the influence of secondary school
background, perception of one’s own health, feeling at risk for COVID‐19 and their own experience
with it and scientific knowledge related to SARS‐CoV‐2 vaccination. It was a cross‐sectional study
with a mixed methodology for data analysis. A questionnaire was applied online to a sample of 102
university students. Results show that students who had already taken the subject on the immune
system and vaccination had more acceptable conceptions about the vaccine and wanted to be vac‐
cinated but not in the initial moment of the national vaccination process. The fear of adverse reac‐
tions seemed to be the major hesitancy factor. Furthermore, students’ argumentation showed that
their conceptions progressed towards more socio‐scientific reasoning.info:eu-repo/semantics/publishedVersio
Damage threshold of CuCrFeTiV high entropy alloys for nuclear fusion reactors
A CuCrFeTiV high entropy alloy was prepared and irradiated with swift heavy ions in order to check its adequacy for use as a thermal barrier in future nuclear fusion reactors. The alloy was prepared from the elemental powders by ball milling, followed by consolidation by spark plasma sintering at 1178 K and 65 MPa. The samples were then irradiated at room temperature with 300 keV Ar+ ions with fluences in the 3 × 1015 to 3 × 1018 Ar+/cm2 range to mimic neutron-induced damage accumulation during a duty cycle of a fusion reactor. Structural changes were investigated by X-ray diffraction, and scanning electron microscopy and scanning transmission electron microscopy, both coupled with X-ray energy dispersive spectroscopy. Surface irradiation damage was detected for high fluences (3 × 1018 Ar+/cm2) with formation of blisters of up to 1 μm in diameter. Cross-sectional scanning transmission electron microscopy showed the presence of intergranular cavities only in the sample irradiated with 3 × 1018 Ar+/cm2, while all irradiation experiments produced intragranular nanometric-sized bubbles with increased density for higher Ar+ fluence. The Williamson-Hall method revealed a decrease in the average crystallite size and an increase in residual strain with increasing fluence, consistent with the formation of Ar+ bubbles at the irradiated surface.publishedVersio
