PERCEIVED STRESS SCALE (PSS-10) APLICADA A ASSISTENTES SOCIAIS EM PORTUGAL: ESTUDO DAS PROPRIEDADES PSICOMÉTRICAS

Objetivo: O presente estudo examina e avalia as propriedades psicométricas da versão de dez itens da Perceived Stress Scale (PSS-10), aplicada à classe profissional dos assistentes sociais em Portugal. Método: A amostra foi composta por 1369 assistentes sociais, maioritariamente (94,01%) do sexo feminino, com uma média etária de 39,02 anos (DP = 8.99). A consistência interna foi verificada por meio do coeficiente Alfa de Cronbach e a validade de constructo, por análise fatorial exploratória através da rotação varimax de componentes principais da PSS-10 e pela análise factorial confirmatória. Resultados: A versão da PSS-10 exibe propriedades psicométricas satisfatórias, mostrando ser um instrumento claro e confiável para mensurar os níveis de stress percecionados pelos assistentes sociais em Portugal. A análise fatorial exploratória revelou dois fatores neste estudo e a análise fatorial confirmatória produziu resultados satisfatórios. A consistência interna apresentou valor de α = 0,84.  Article visualizations

Social disaffiliation : contemporary ambiguities and multi-realities

Intervenção social. - ISSN 0874-1611. - N. 37 (1.º semestre 2011). - p. 93-108.O presente artigo aborda as multirealidades do conceito de desafiliação social, encarado como processo extremo de exclusão social no seio das ambiguidades presentes nas sociedades contemporâneas. Tem por objectivo ser um contributo para que os estudantes e profissionais de serviço social possam reflectir sobre o fenómeno das desigualdades sociais produzidas pelo processo de globalização, sobretudo, no que diz respeito aos fenómenos da pobreza e da exclusão social. Fenómenos que colocam desafios ao serviço social, na tripla perspectiva da sua actuação: interventiva, política e científica, de forma a que, como ciência social aplicada, a disciplina possa melhor contribuir na resolução destes graves problemas sociais e na promoção de sociedades inclusivas e solidárias

Craques de bola, mandinga e piruetas : experiência sociodesportiva e identidades juvenis no Bairro Padre Cruz

Tese de doutoramento em Serviço Social, Universidade Lusíada de Lisboa, 2020Exame público realizado em 2 de Julho de 2021Tem-se verificado um aumento do interesse das Ciências Sociais pela temática da inclusão social no e pelo desporto. Contudo, o estudo da importância da experiência sociodesportiva na construção de identidades, culturas e espaços informais de capacitação juvenis, em contextos de vulnerabilidade social, é escasso no campo do Serviço Social nacional. ‘Craques de bola, mandinga e piruetas’ consiste numa investigação compreensiva, de cariz etnográfico, que recorrendo à observação in loco num ‘bairro social’ de Lisboa, o Bairro Padre Cruz (BPC) foi capaz de identificar modelos de prática, no que concerne à intervenção preconizada pela comunidade sociodesportiva local, os turning points da construção identitária juvenil e o ideais tipos identitários produzidos no campo da experiência vivenciada pelas juventudes em presença, no âmbito de vários projetos comunitários que recorrem ao futebol de rua, à capoeira, à dança hip hop e ao circo social, como ferramentas colaborativas de mediação e educação informal para a cidadania. Esta imersão permitiu compreender os múltiplos contextos onde as identidades juvenis se desenvolvem, as trajetórias, comunidades e sociabilidades, a vivência e tentativas de superação das vulnerabilidades, nos espaços informais do lazer desportivo. Espera-se contribuir para maior visibilidade dos processos identitários, de auto-regulação e capacitação juvenil possibilitados pela experiência sociodesportiva, trazendo implicações na promoção da inclusão social, na legitimação das identidades juvenis e no desenvolvimento de ferramentas teórico-práticas no campo do Serviço Social comunitário e em contexto urbano.There has been an increase in the interest of the Social Sciences in the theme of social inclusion in and by sport. However, there are limited studies in the national social work field about the importance of the socio-sports experience in the construction of identities, cultures and informal spaces for youth empowerment, in contexts of social vulnerability. 'Ball, mandinga and pirouettes stars' consists of a comprehensive ethnography which, by using on-site observation in a Lisbon “social neighbourhood”, Padre Cruz neighbourhood (BPC), was able to identify the pratice models proposed by the local socio-sports community, the turning points of youth identity construction and the identity ideal types produced by the experiences lived by the youth, within the framework of various community projects that use street soccer, capoeira, hip hop dance and social circus as collaborative tools of mediation and informal education for citizenship. This immersion allowed the understanding of the multiple contexts where youth identities develop, their trajectories, communities and sociabilities, the experience and attempts to overcome vulnerabilities, in the informal spaces of sports leisure. This study is expected to contribute to a greater visibility of the identity processes, self-regulation and youth empowerment made possible by the socio-sports experience, explaining the implications for the promotion of social inclusion, the legitimization of youth identities and for the development of theoretical and practical tools in the field of community social work in and urban context

Desporto, lazer e intervenção social : reflexões e práticas críticas

Intervenção social. - ISSN 0874-1611. - N. 47-48 (1.º e 2.º semestre de 2016). - p. 185-189O Serviço Social como disciplina interdisciplinar promove o debate com outras ciências sociais. A operacionalização de práticas de lazer desportivo no âmbito da profissão permite abordagens inovadoras numa perspetiva crítica. Através dos contributos teóricos e da promoção do debate codisciplinar das ciências do desporto e sociais, sobretudo entre a sociologia, a antropologia e a motricidade humana, produz novos olhares, que se cruzam com práticas profissionais dos assistentes sociais e que permitem refletir e desafiar visões hegemónicas do fenómeno desportivo e da sua influência na vida social. Estas práticas encaradas como elementos de mediação social da experiência sociodesportiva dos sujeitos, no mundo contemporâneo, permitem repensar e refletir sobre o lugar do desporto e do lazer na vida humana e produzir conhecimento colaborativo no campo do serviço social. É, assim, objetivo deste simpósio trazer ao debate a temática do ‘desporto, lazer e intervenção social’ de forma a dar a conhecer reflexões e práticas críticas, que se têm vindo a afirmar no campo das perspetivas críticas do desporto e do serviço social. Correntes que encontram no campo sociodesportivo, promovido nos espaços e agires da intervenção social, um espaço de partilha inovador. Pretende-se estimular a intervenção e a investigação interdisciplinar no campo do serviço social, apresentando a par das reflexões teóricas sobre o tema, exemplos de saberes da ação e de coprodução de conhecimento promovidos em comunidades de práticas sociodesportivas. Em suma, a realização deste simpósio estimula a reflexividade crítica sobre o modo como o fenómeno desportivo pode ser ferramenta de transformação do mundo, no âmbito do agir profissional dos interventores sociais, possibilitando a discussão de novos e alternativos domínios teóricos, advindos das práticas do serviço social

Hepatic Osteodystrophy: The Mechanism of Bone Loss in Hepatocellular Disease and the Effects of Pamidronate Treatment

OBJECTIVES: The present study was designed to evaluate the bone phenotypes and mechanisms involved in bone disorders associated with hepatic osteodystrophy. Hepatocellular disease was induced by carbon tetrachloride (CCl4). In addition, the effects of disodium pamidronate on bone tissue were evaluated. METHODS: The study included 4 groups of 15 mice: a) C = mice subjected to vehicle injections; b) C+P = mice subjected to vehicle and pamidronate injections; c) CCl4+V = mice subjected to CCl4 and vehicle injections; and d) CCl4+P = mice subjected to CCl4 and pamidronate injections. CCl4 or vehicle was administered for 8 weeks, while pamidronate or vehicle was injected at the end of the fourth week. Bone histomorphometry and biomechanical analysis were performed in tibiae, while femora were used for micro-computed tomography and gene expression. RESULTS: CCl4 mice exhibited decreased bone volume/trabecular volume and trabecular numbers, as well as increased trabecular separation, as determined by bone histomorphometry and micro-computed tomography, but these changes were not detected in the group treated with pamidronate. CCl4 mice showed increased numbers of osteoclasts and resorption surface. High serum levels of receptor activator of nuclear factor-κB ligand and the increased expression of tartrate-resistant acid phosphatase in the bones of CCl4 mice supported the enhancement of bone resorption in these mice. CONCLUSION: Taken together, these results suggest that bone resorption is the main mechanism of bone loss in chronic hepatocellular disease in mice

The Ternary Rab27a–Myrip–Myosin VIIa Complex Regulates Melanosome Motility in the Retinal Pigment Epithelium

The retinal pigment epithelium (RPE) contains melanosomes similar to those found in the skin melanocytes, which undergo dramatic light-dependent movements in fish and amphibians. In mammals, those movements are more subtle and appear to be regulated by the Rab27a GTPase and the unconventional myosin, Myosin VIIa (MyoVIIa). Here we address the hypothesis that a recently identified Rab27a- and MyoVIIa-interacting protein, Myrip, promotes the formation of a functional tripartite complex. In heterologous cultured cells, all three proteins co-immunoprecipitated following overexpression. Rab27a and Myrip localize to the peripheral membrane of RPE melanosomes as observed by immunofluorescence and immunoelectron microscopy. Melanosome dynamics were studied using live-cell imaging of mouse RPE primary cultures. Wild-type RPE melanosomes exhibited either stationary or slow movement interrupted by bursts of fast movement, with a peripheral directionality trend. Nocodazole treatment led to melanosome paralysis, suggesting that movement requires microtubule motors. Significant and similar alterations in melanosome dynamics were observed when any one of the three components of the complex was missing, as studied in ashen- (Rab27a defective) and shaker-1 (MyoVIIa mutant)-derived RPE cells, and in wild-type RPE cells transduced with adenovirus carrying specific sequences to knockdown Myrip expression. We observed a significant increase in the number of motile melanosomes, exhibiting more frequent and prolonged bursts of fast movement, and inversion of directionality. Similar alterations were observed upon cytochalasin D treatment, suggesting that the Rab27a–Myrip–MyoVIIa complex regulates tethering of melanosomes onto actin filaments, a process that ensures melanosome movement towards the cell periphery

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
