The impact of graduate training on teachers and schools – two case studies: graduate teachers’ perceptions

The main goal of this study is to research the impact of enrolment in Graduate Programmes (GPs) on a set of Basic Education2 and High School3 teachers in Portugal. We seek to understand whether teachers consider this training as an added value, and the extent to which this is reflected in the improvement of their professional performance, in the schools, and in their students’ learning. Preliminary research results show, among other aspects, that the reasons why teachers enrol in GPs are associated mainly with personal fulfilment issues. Moreover, despite the fact that both teachers and school leaders recognize the importance of GPs, they acknowledge that there are still few effects.info:eu-repo/semantics/publishedVersio

The impacts of teachers’ post-graduate training in Portuguese schools

A investigação apresentada teve como problema central estudar o impacto da Formação Pós-Graduada (FPG) de professores do Ensino Básico (EB) e do Ensino Secundário (ES) em dois agrupamentos de escolas em Portugal. Procurámos entender se os professores assumem essa formação como um benefício e de que forma isso se manifesta na melhoria do seu desempenho profissional, das escolas e das aprendizagens dos alunos. Apresentámos, ainda, sugestões para potencializar os efeitos da FPG frequentada por professores.The main aim of the present study was to focus on the impact of post-graduation education on primary and secondary schoo teachers from two school clusters in Portugal.

We also presented suggestions to potentiate the effects of post-graduate training attended by teachers.info:eu-repo/semantics/publishedVersio

Xylanase from Fusarium heterosporum: Properties and influence of thiol compounds on xylanase activity

The properties of xylanase purified from Fusarium heterosporum that was grown in barley-brewing residue under solid-state fermentation and the effects of thiol compounds on the reactivation of the metal ion-inhibited xylanase were investigated. Xylanase was purified to homogeneity by ion exchange chromatography, and its molecular mass was estimated to be 19.5 kDa by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The optimum pH for the xylanase was 5.0, and it was stable in acidic pH (4.5 to 5.5), where it retained more than 87% of its activity after 24 h. The optimum temperature was 50°C, and it had a half-life of 53 min at 45°C. The apparent Km and Vmax values for the xylanase were 5.63 mg/ml and 800 μmol/mg/min, respectively. Ba2+, Ca2+, Mg2+ and the thiol compounds β-mercaptoethanol and dithiothreitol (DTT) enhanced xylanase activity, while Hg2+, Pb2+ and Zn2+ strongly inhibited enzyme activity. Furthermore, this xylanase had an alternative mode of regulation in the presence of thiol compounds because the enzyme was able to recover its catalytic activity after inhibition by heavy metal ions.Keywords: Hemicellulase, fungus, solid-state fermentation, barley brewing residue, thiol compoundsAfrican Journal of Biotechnology, Vol. 13(9), pp. 1047-1055, 26 February, 201

Factor IX Expression within the Normal Range Prevents Spontaneous Bleeds Requiring Treatment Following FLT180a Gene Therapy in Patients with Severe Hemophilia B: Long-Term Follow- up Study of the B-Amaze Program

Introduction: FLT180a (verbrinacogene setparvovec) is an investigational, liver-directed AAV gene therapy for the treatment of patients with hemophilia B (HB). FLT180a consists of a novel, potent, engineered capsid (AAVS3) containing an expression cassette encoding a Factor IX (FIX) gain-of-function protein variant ('Padua'; FIX-R338L). The B-AMAZE study was designed to identify a dose of FLT180a that maintains FIX activity within the normal range (50-150%) and thereby protect patients with severe HB from spontaneous and traumatic bleeds. Methods: B-AMAZE was a multicentre, open-label Phase 1/2 clinical trial (NCT03369444; sponsored by UCL) that evaluated FLT180a dose levels using an escalating/descending adaptive design in patients with severe (FIX activity &amp;lt;1%) or moderately severe (FIX activity 1-2%) HB who were negative for AAVS3 neutralizing antibodies. A novel regimen of prophylactic corticosteroids with/without tacrolimus was implemented to mitigate the impact of vector-related transaminitis on FIX expression. Patients who completed the 26-week B-AMAZE study were eligible for the ongoing long-term follow-up study (NCT03641703; sponsored by Freeline). Results: Ten HB patients received a single dose of FLT180a. Four FLT180a doses ranging from 3.84e11 vg/kg to 1.28e12 vg/kg were assessed. As of the data cut-off date, all patients have been followed for ≥16 months. FLT180a demonstrated a favorable safety profile, without evidence of inhibitors against FIX, infusion-related or allergic reactions. The most common treatment-related adverse event was transient elevation in alanine aminotransferase. An event of AV fistula thrombosis occurred in a 67-year-old patient who received the highest dose of 1.28e12 vg/kg (total dose of 1.15e14 vg) and had supranormal FIX levels; this patient was treated with anticoagulants. While these FIX levels demonstrate the potency of our proprietary AAVS3 capsid, this dose will not be used in future hemophilia studies. At Week 26 after FLT180a administration, a dose-response relationship was observed with mean FIX activity of 45.0%, 35.5%, 141.5%, and 175.5% for 3.84e11, 6.4e11, 8.32e11, and 1.28e12 vg/kg doses, respectively (Table); FIX activity levels ≥50% were achieved in 7 of 8 patients treated with the three highest doses. One patient (Patient 4) who received 6.4e11 vg/kg lost transgene expression early due to transaminitis and resumed routine factor prophylaxis. The 8.32e11 vg/kg cohort received an extended immune management regimen (9-18 weeks) with prophylactic tacrolimus in addition to prednisolone to prevent breakthrough vector-related transaminitis. However, after cessation of the immune management regimen, transaminitis with concomitant reductions in FIX activity was observed in all patients in the 8.32e11 vg/kg cohort. The combination of prophylactic tacrolimus and prednisolone appeared to have suppressed immune-mediated transaminitis while administered, but recurrence of transaminitis developed soon after cessation. This unique and previously unreported observation suggests that the longer-duration prophylactic immune management regimen may have prevented tolerization to the vector because this was not observed in earlier cohorts where a brief course of tacrolimus was given reactively for breakthrough transaminitis. All patients (including the 8.32e11 vg/kg cohort) have achieved steady state. Patients in the earliest cohort who received the lowest dose (3.84e11 vg/kg) have shown stable FIX activity for &amp;gt;3 years. There were no spontaneous bleeds that required FIX supplementation in patients who maintained FIX activity above 50%; Patient 4 in the 6.4e11 vg/kg cohort experienced two bleeds (cause unknown) after he lost transgene expression, which were treated with exogenous FIX. One patient received exogenous FIX for treatment of a traumatic bleed, but his FIX activity level was 57% at the time of the event. Additional efficacy and safety results with &amp;gt;3.5 years of follow-up will be presented. Conclusions: B-AMAZE is the first HB gene therapy study to achieve normal levels of FIX activity using relatively low vector doses. Results suggest that a dose of 7.7e11 vg/kg, coupled with a short course of prophylactic immune management, has the potential to achieve durable FIX activity in the normal range (50-150%) and thereby prevent spontaneous bleeds and normalize hemostasis in the event of traumatic bleeds

LOCUS (LOng Covid-Understanding Symptoms, events and use of services in Portugal): A three-component study protocol

Study ProtocolApproximately 10% of patients experience symptoms of Post COVID-19 Condition (PCC) after a SARS-CoV-2 infection. Akin acute COVID-19, PCC may impact a multitude of organs and systems, such as the cardiovascular, respiratory, musculoskeletal, and neurological systems. The frequency and associated risk factors of PCC are still unclear among both community and hospital settings in individuals with a history of COVID-19. The LOCUS study was designed to clarify the PCC’s burden and associated risk factors. LOCUS is a multi-component study that encompasses three complementary building blocks. The “Cardiovascular and respiratory events following COVID-19” component is set to estimate the incidence of cardiovascular and respiratory events after COVID-19 in eight Portuguese hospitals via electronic health records consultation. The “Physical and mental symptoms following COVID-19” component aims to address the community prevalence of self-reported PCC symptoms through a questionnaire-based approach. Finally, the "Treating and living with Post COVID-19 Condition" component will employ semi-structured interviews and focus groups to characterise reported experiences of using or working in healthcare and community services for the treatment of PCC symptoms. This multi-component study represents an innovative approach to exploring the health consequences of PCC. Its results are expected to provide a key contribution to the optimisation of healthcare services design.This study is sponsored by Pfizer (grant code #68639655).info:eu-repo/semantics/publishedVersio

INSTRUMENTOS DE AVALIAÇÃO DA INCAPACIDADE E FUNCIONALIDADE DE TRABALHADORES COM DISTÚRBIOS MUSCULOESQUELÉTICOS RELACIONADOS AO TRABALHO: ANÁLISE DAS PROPOSTAS EXISTENTES

Trata-se de uma revisão da literatura sobre instrumentos de avaliação de incapacidade e funcionalidade de trabalhadores com Distúrbios Musculoesqueléticos (DME) com vista ao retorno ao trabalho em uma perspectiva biopsicossocial. Abrange o período de dez anos, com levantamento bibliográfico nas bases de dados do Pubmed, Scopus, Psycoinfo, CINAHL, utilizando palavras-chaves relacionadas a protocolos de avaliação de incapacidade e funcionalidade para trabalhadores com DME. Apenas oito artigos abordavam o tema de interesse. Os artigos foram analisados nas dimensões biomédica, psicossocial e relacionada ao trabalho. Foram identificados 23 instrumentos para avaliação de incapacidade. Dentre os instrumentos com itens em mais de uma dimensão, foram encontrados seis que incorporaram as dimensões biomédica e psicossocial, três com itens de todas as dimensões e apenas um instrumento com itens das dimensões psicossocial e relacionada ao trabalho. Essa revisão mostra que são escassos os relatos sobre a existência e uso de instrumentos validados que tratem das dimensões biomédica, psicossocial e relacionada ao trabalho.  Os instrumentos que utilizam uma abordagem compreensiva incluindo entrevista em profundidade e instrumentos validados podem ser um facilitador para o levantamento das demandas biopsicossociais do trabalhador doente

Poor Sleep quality and health-related quality of life impact in adolescents with and without chronic immunosuppressive conditions during COVID-19 quarantine

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18)&nbsp;vs. 15 (10-18) years,&nbsp;p=0.847] and frequency of female sex (62%&nbsp;vs. 58%,&nbsp;p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38%&nbsp;vs. 48%,&nbsp;p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8;&nbsp;p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5;&nbsp;p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99;&nbsp;p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8;&nbsp;p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4;&nbsp;p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98;&nbsp;p&lt;0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality

Viral genetic clustering and transmission dynamics of the 2022 mpox outbreak in Portugal

Pathogen genome sequencing during epidemics enhances our ability to identify and understand suspected clusters and investigate their relationships. Here, we combine genomic and epidemiological data of the 2022 mpox outbreak to better understand early viral spread, diversification and transmission dynamics. By sequencing 52% of the confirmed cases in Portugal, we identified the mpox virus sublineages with the highest impact on case numbers and fitted them into a global context, finding evidence that several international sublineages probably emerged or spread early in Portugal. We estimated a 62% infection reporting rate and that 1.3% of the population of men who have sex with men in Portugal were infected. We infer the critical role played by sexual networks and superspreader gatherings, such as sauna attendance, in the dissemination of mpox virus. Overall, our findings highlight genomic epidemiology as a tool for the real-time monitoring and control of mpox epidemics, and can guide future vaccine policy in a highly susceptible population.info:eu-repo/semantics/publishedVersio
