Compreender as conceções de aprendizagem da população reclusa: um estudo fenomenográfico

Dissertação de mestrado integrado em Psicologia (área de especialização em Psicologia da Justiça)Baixos níveis de ensino, abandono escolar precoce e historial limitado de emprego, contribuem para o envolvimento criminal. O sistema prisional português oferece a possibilidade de os reclusos continuarem a sua formação escolar, contudo a taxa de adesão é reduzida e a de desistência elevada. Por estes motivos é importante analisar a forma como os reclusos percecionam a aprendizagem e o modo como aprendem. Este estudo fenomenográfico com 30 reclusos Portugueses, de idades compreendidas entre os 20 e os 58 anos de idade, revelou que estes interpretam a sua aprendizagem como aprender para saber, para se integrar, para perceber o propósito, para beneficiar, para se corrigir e para evoluir. Consequentemente, referem que o processo de aprendizagem ocorre fazendo coisas, pedindo ajuda, dando exemplo aos seus filhos, participando frequente e assiduamente nas aulas, refletindo nos seus erros e tornando o seu tempo útil. A aprendizagem é percebida pelos reclusos alunos como oportunidade de mudança e evolução. As implicações para os processos educativos e práticas escolares em meio prisional são também consideradas.Low levels of education, early school leaving and limited employment history, contribute to the criminal involvement. The Portuguese prison system offers the possibility of inmates completing their education. However the rate of adhesion is reduced and the rate of dropout is high. For these reasons, it is important to analyze how the inmates perceived their learning as well as how they learn. Data from a phenomenographic study of 30 Portuguese inmates students, ranging from 20 to 58 years of age, revealed that they understand their learning as learning to know, to integrate, to seeing purpose, to benefit, to correct themselves and to evolve. Consequently, they notice their learning process occurs doing things, asking for help, giving example to their children, participating assiduously in the classroom, reflecting on their mistakes and making their time useful. Hence, learning is perceived as an opportunity for change and evolve. The implications for educational processes and school practices in prison are considered

From August 2016 to September 2019, 6162 neonates and juveniles of 5 different shark species were observed in SRB using beach gillnet-based bycatch surveys, namely milk (Rhizoprionodon acutus; n= 4908), scalloped hammerhead (Sphyrna lewini; n= 1035), blacktip (Carcharhinus limbatus; n=115), Atlantic weasel (Paragaleus pectoralis; n= 93) and nurse (Ginglymostoma cirratum; n= 12) sharks. Except for nurse sharks, significant seasonal variations in shark relative abundance were observed, with higher levels being recorded during summer and autumn. These findings, together with local knowledge (interviews to fishermen), denote the consistent use of SRB by juvenile sharks and its preference relative to other areas in the region. Ensuring the protection and conservation of SRB nursery area is especially relevant as, according to IUCN, all identified shark species are threatened with extinction over the near-future – in particular, scalloped hammerheads (critically endangered) and Atlantic weasel sharks (endangered). The effective protection of SRB will not only support the conservation of shark populations, but also of other charismatic fauna (e.g., loggerhead turtles) and broader benthic and pelagic ecosystems.Publisher PDFPeer reviewe

The differentiation of stem cells into hepatocyte-like cells (HLC) has been adopted due to its human origin and availability. Our aim was to study the usefulness of an in vitro 3D model of mesenchymal stem cell-derived HLCs. 3D spheroids (3D-HLC) or monolayer (2D-HLC) cultures of HLCs were treated with the hepatotoxic drug nevirapine (NVP) for 3 and 10 days followed by analyses of Phase I and II metabolites, biotransformation enzymes and drug transporters involved in NVP disposition. To ascertain the toxic effects of NVP and its major metabolites, the changes in the glutathione net flux were also investigated. Phase I enzymes were induced in both systems yielding all known correspondent NVP metabolites. However, 3D-HLCs showed higher biocompetence in producing Phase II NVP metabolites and upregulating Phase II enzymes and MRP7. Accordingly, NVP-exposure led to decreased glutathione availability and alterations in the intracellular dynamics disfavoring free reduced glutathione and glutathionylated protein pools. Overall, these results demonstrate the adequacy of the 3D-HLC model for studying the bioactivation/metabolism of NVP representing a further step to unveil toxicity mechanisms associated with glutathione net flux changes.publishersversionpublishe

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

Ureteroneocystostomy after failed dextranomer/hyaluronic acid copolymer injection for vesicoureteral reflux treatment

To report our experience of open ureteroneocystostomy after failed endoscopic treatment.Purpose To report our experience of open ureteroneocystostomy after failed endoscopic treatment. Material and methods Clinical charts of 787 children who entered our dextranomer/hyaluronic acid copolymer (DxHA) endoscopic injection program for vesicoureteral reflux (VUR) treatment between May 2000 and December 2009 were reviewed. Fifty-one of these patients were submitted to open ureteroneocystostomy for complete resolution of VUR. Results Twenty-eight patients (55%) were female. Median age at surgery was 65 months (range: 26–182). Median time going from first endoscopic injection until open surgery was 13 months (range 1–58). Surgical ureteral reimplantation was bilateral in 62.7% of the cases. Of a total of 83 operated ureters, nine were duplex ureters, nine were megaureters, six were ectopic, and two had periureteral diverticulum. Mean operative time was 70 min (range 45–120 min). There were no intra-operative complications. Follow-up VCUG showed complete resolution of VUR in 98% of patients. There was only one right-sided grade III VUR that persisted after bilateral reimplantation. It resolved with a single subureteral DxHA injection. Conclusions Ureteroneocystostomy after a failed endoscopic treatment can achieve successful results in a high percentage of patients with minimal complications

Phaeodactylum tricornutum extracts as structuring agents for food applications: Physicochemical and functional properties

Microalgae are a promising and sustainable ingredient for functional food development, due to their rich nutritional and health-promoting effects. Moreover, microalgae generally contain large amounts of structural biopolymers such as proteins and polysaccharides, which might display interesting technological features and rheological properties. This study aims at unravelling Phaeodactylum tricornutum extracts (PTE) potential role as structuring agents for food applications. Distilled water and a mixture of water/ethanol (75/25, v v1) were used as solvents. Extracts physicochemical properties were analysed regarding protein folding, molecular weight distribution, polymer interactions, and their main functional groups. PTE thermal properties, rheological behaviour, and emulsifying capacities were also evaluated. PTE showed different gelling mechanisms, with 40°C aqueous purified extracts reporting the strongest gel character. Moreover, 80°C ethanolic purified extracts showed the greatest emulsifying potential, with an initial emulsification index (EI) of around 90%. This EI decreased to 60% after 10 days, but remained constant for the following 15 days, showing an interesting emulsion stability. Overall, these findings suggest that PTE have a great potential for further application as thickening or emulsifier food ingredients.
