UCSD Performance-Based Skills Assessment (UPSA): validation of a Brazilian version in patients with schizophrenia

AbstractThe UCSD Performance-based Skills Assessment (UPSA) is a measure of Functional Capacity and assesses skills involved in community tasks. It has good psychometrics properties, and is currently recommended as a co-primary assessment of cognition in the MATRICS Project. To our knowledge so far, there are no studies in western developing countries concerning Functional Capacity in Schizophrenia. The aims of this study were to translate, culturally adapt and validate the UPSA to assess Functional Capacity in community-dwelling patients with Schizophrenia living in Brazil. Eighty-two subjects (52 patients, 30 controls) were evaluated using: the Brazilian version of the UPSA (UPSA-1-BR), PANSS, Personal and Social Performance (PSP) and Global Assessment of Functioning (GAF). In the reliability test, UPSA-1-BR showed good Internal Consistency (Cronbach’s alpha of 0.88) and strong correlation between test and retest (4-month gap; r = 0.91; p < 0.01). Spearman’s rho values showed a moderate correlation between UPSA-1-BR and both PSP (0.50; p < 0.01) and GAF (0.46; p < 0.01) scores. UPSA-1-BR is capable of differentiating people with and without Schizophrenia. Patients scored lower than controls (58.9 versus 79.1), with an AUC of 0.79 (95%IC: 0.69–0.89). Sensitivity and specificity values of 0.71 and 0.70, respectively, were found in the cut-off point of 73.5, for separation of patients and controls, with predictive values of 80% (positive) and 58% (negative). UPSA-B-BR was also evaluated. UPSA-1-BR and its brief version presented adequate psychometric properties and proved to be valid and reliable instruments in the assessment of Functional Capacity in subjects with Schizophrenia

Analysis of the backpack loading efects on the human gait

Gait is a simple activity of daily life and one of the main abilities of the human being. Often during leisure, labour and sports activities, loads are carried over (e.g. backpack) during gait. These circumstantial loads can generate instability and increase biomechanicalstress over the human tissues and systems, especially on the locomotor, balance and postural regulation systems. According to Wearing (2006), subjects that carry a transitory or intermittent load will be able to find relatively efficient solutions to compensate its effects.info:eu-repo/semantics/publishedVersio

O projecto nacional de educação pelos pares da Fundação Portuguesa “A comunidade contra a sida” em escolas EB2/3 do Porto

O Projecto Nacional de Educação pelos Pares, focado na sexualidade e prevenção do VIH/ SIDA, foi criado pela Fundação Portuguesa “A Comunidade Contra a SIDA” no âmbito do Centro de Aconselhamento e Orientação de Jovens (CAOJ). O processo de aprendizagem, desenvolvido a partir do diagnóstico das necessidades de formação do público-alvo, recorre a metodologias activas que visam educar os adolescentes para uma vivência gratificante da sua sexualidade e prepará-los para assumirem o seu papel de “pares educadores” de colegas mais jovens. Esta educação de pares dirigida a alunos que frequentam o 3º ciclo do Ensino Básico é dinamizada, numa primeira fase, por jovens voluntários universitários organizados em Brigadas Universitárias de Intervenção (BUI) e no Teatro Universitário de Intervenção (TUI). Estes voluntários, com o acompanhamento de professores destacados para o CAOJ, responsáveis pela sua formação pedagógica, desenvolvem o projecto com alunos do 7º ao 9º ano de escolaridade. No terceiro ano de formação, os alunos do 3º ciclo organizados em Brigadas Escolares de Intervenção (BEI) iniciam a sua acção como educadores dos colegas mais novos, geralmente dos 2º e 1º ciclos. Esta comunicação, pretende mostrar a dinâmica deste Projecto desenvolvido em cinco escolas EB2/3 do Porto e discutir, com base em evidências recolhidas junto dos professores, voluntários e alunos envolvidos, alguns resultados obtidos neste ano lectivo

Contributos da biomecânica para o estudo do rendimento desportivo em natação

Na actualidade, o progresso do rendimento desportivo ao mais alto nível só é susceptível de ser conseguido através de uma combinação (que diríamos necessariamente feliz) de um vasto conjunto de factores: é necessário desde logo um pouco de sorte (como em tudo na vida – mesmo que seja para cozinhar a sopa de pedra requerida), mas sobretudo um praticante talentoso e motivado, condições de treino adequadas, um envolvimento global propício, uma equipa directiva competente e motivada e uma equipa técnica pluridisciplinar devidamente habilitada e coordenada. No quadro das habilitações desta deve-se destacar a sua sensibilidade e vocação para a contínua avaliação do seu próprio desempenho e do desempenho do seu nadador, para a consideração, ponderação e experimentação de novas opções, para a inovação tecnológica e científica. Apesar de no universo desportivo a inércia científica (e tecnológica) ser ainda superior à verificada noutros domínios da sociedade contemporânea (às vezes por estrito exercício de um carácter “bota de elástico”), são já muitos (e de há muito) os exemplos frutuosos da sua incorporação no quotidiano, seja como background cultural apenas, seja como prática efectiva. No futuro serão cada vez mais; e serão cada vez menos os espaços para o “por acaso”, para o “surpreendente”, para a geração espontânea do campeão apesar de quem o treina. No futuro – e num futuro que se já vem fazendo presente – não haverá nadadores ou treinadores de sucesso que não apelem, mais ou menos exuberantemente, a auxiliares científicos e tecnológicos para o treino

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
