Photovoice como estratégia de intervenção socioeducativa com crianças, jovens e pessoas idosas: perspetivas de futuros Educadores Sociais
O photovoice é uma metodologia de investigação-ação participativa que permite a partilha de conceções e experiências vividas através de fotografias com o propósito de melhorar aspetos das comunidades em que é desenvolvido. O seu uso tem sido privilegiado em comunidades marginalizadas ou em desvantagem. É uma das metodologias apresentadas na formação de Educadores Sociais da Escola Superior de Educação de Viseu, dada a sua difusão quer como ferramenta de intervenção quer como instrumento de investigação. Durante a formação destes profissionais, é importante criar situações e usar metodologias em que os estudantes possam considerar a sua própria atuação e refletir criticamente sobre crenças fundamentais relacionadas com a realidade e com os contextos de intervenção. Várias experiências internacionais e nacionais têm revelado vantagens importantes da utilização pedagógica do photovoice no ensino superior. Este estudo procurou caraterizar as perspetivas de estudantes do 3.º ano da licenciatura no final do seu curso sobre a metodologia enquanto estratégia de intervenção socioeducativa, no que diz respeito à experiência de utilização da metodologia num trabalho realizado no âmbito das unidades curriculares de Intervenção socioeducativa com crianças e jovens e Intervenção socioeducativa com pessoas idosas, e às possibilidades de utilização da metodologia no futuro profissional. Ambos os conjuntos de dados foram sujeitos a uma análise de conteúdo que demonstrou que os participantes consideram vantagens significativas na utilização da metodologia quer como estratégia formativa quer como estratégia de intervenção profissional.info:eu-repo/semantics/publishedVersio
Desenhando as novas fronteiras para a compreensão do transtorno obsessivo-compulsivo: uma revisão de sua relação com o medo e a ansiedade
Anxiety is an important component of the psychopathology of the obsessive-compulsive disorder (OCD). So far, most interventions that have proven to be effective for treating OCD are similar to those developed for other anxiety disorders. However, neurobiological studies of OCD came to conclusions that are not always compatible with those previously associated with other anxiety disorders. OBJECTIVES: The aim of this study is to review the degree of overlap between OCD and other anxiety disorders phenomenology and pathophysiology to support the rationale that guides research in this field. RESULTS: Clues about the neurocircuits involved in the manifestation of anxiety disorders have been obtained through the study of animal anxiety models, and structural and functional neuroimaging in humans. These investigations suggest that in OCD, in addition to dysfunction in cortico-striatal pathways, the functioning of an alternative neurocircuitry, which involves amygdalo-cortical interactions and participates in fear conditioning and extinction processes, may be impaired. CONCLUSION: It is likely that anxiety is a relevant dimension of OCD that impacts on other features of this disorder. Therefore, future studies may benefit from the investigation of the expression of fear and anxiety by OCD patients according to their type of obsessions and compulsions, age of OCD onset, comorbidities, and patterns of treatment response
Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part II: cognitive-behavioral therapy
Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD
Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC
Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
The genetic architecture of the human cerebral cortex
The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Early role of vascular dysregulation on late-onset Alzheimer's disease based on multifactorial data-driven analysis
Multifactorial mechanisms underlying late-onset Alzheimer's disease (LOAD) are poorly characterized from an integrative perspective. Here spatiotemporal alterations in brain amyloid-β deposition, metabolism, vascular, functional activity at rest, structural properties, cognitive integrity and peripheral proteins levels are characterized in relation to LOAD progression. We analyse over 7,700 brain images and tens of plasma and cerebrospinal fluid biomarkers from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Through a multifactorial data-driven analysis, we obtain dynamic LOAD–abnormality indices for all biomarkers, and a tentative temporal ordering of disease progression. Imaging results suggest that intra-brain vascular dysregulation is an early pathological event during disease development. Cognitive decline is noticeable from initial LOAD stages, suggesting early memory deficit associated with the primary disease factors. High abnormality levels are also observed for specific proteins associated with the vascular system's integrity. Although still subjected to the sensitivity of the algorithms and biomarkers employed, our results might contribute to the development of preventive therapeutic interventions
Trajectory in Obsessive-Compulsive Disorders Comorbidities
Introdução: O transtorno obsessivo-compulsivo (TOC) é uma doença de etiologia complexa, podendo ser influenciada por inúmeros fatores genéticos e ambientais. A falta de homogeneidade na descrição do transtorno dificulta a pesquisa de fatores etiológicos. Um dos subgrupos de TOC com características mais homogêneas é o TOC de início precoce. O objetivo principal deste estudo é investigar o efeito da idade de início dos diversos sintomas nas características clínicas dos transtornos psiquiátricos do Eixo I na trajetória evolutiva de pacientes com TOC. Metodologia: 1001 pacientes com TOC de acordo com os critérios do DSM-IV foram avaliados de forma direta com os instrumentos: Escala Dimensional para Avaliação de Presença e Gravidade de Sintomas Obsessivo-Compulsivos (DY-BOCS), Escala Yale-Brown de Sintomas Obsessivo-Compulsivos (Y-BOCS), Entrevista Clínica Estruturada para o DSM-IV - Transtornos do Eixo I (SCID-I/P), Inventários de Ansiedade e de Depressão de Beck, Questionário de História Natural do TOC e Escala de Crenças de Brown. Para comparação das variáveis categoriais foram realizados os testes qui-quadrado e para variáveis numéricas testes não paramétricos de Kruskal-Wallis e testes paramétricos tipo ANOVA. Foram considerados para todos os testes nível de significância de 5%. O estudo das idades de início das comorbidades foi realizado utilizando a abordagem bayesiana. Resultados: Pacientes com início precoce tiveram maior frequência de Ansiedade de Separação (p<0,001); Transtorno de Déficit de Atenção e Hiperatividade (p=0,031); Tiques (p=0,009); Espectro Obsessivo-Compulsivo (OC) (p<0,001); Transtornos do Impulso (p=0,005); e do Humor (p=0,020). Além disso, tiveram maior gravidade em todas as medidas de escore nas escalas Y-BOCS (p<0,001) e DY-BOCS (p<0,001), curso com piora progressiva do TOC (p<0,001) e maior frequência de história familiar de TOC (p<0,001) e transtornos de Tiques (p=0,013). Pacientes com TOC que apresentaram ansiedade de separação como primeiro diagnóstico tiveram uma tendência a apresentar maior frequência de: Transtornos Ansiosos (p=0,058), Somatoformes (p=0,056), TEPT (p=0,004), maior gravidade na dimensão Sexual/Religioso (p=0,053) e escores mais elevados nas escalas Beck depressão (p=0,005) e Beck ansiedade (p<0,001). Pacientes com TOC que apresentaram TDAH como primeiro diagnóstico tiveram maior frequência de Abuso de Substância (p<0,001) e apresentaram um curso com piora mais progressiva do TOC comparados com os outros grupos (p=0,033). Pacientes com TOC que apresentaram transtornos de tiques como primeiro diagnóstico tiveram maior frequência de Transtornos do Espectro OC (p=0,034). Conclusão: O TOC é um transtorno heterogêneo que pode compreender diversos subtipos de acordo com a abordagem escolhidaIntroduction: Obsessive-Compulsive Disorder (OCD) has a complex etiology, and can be influenced by several genetic and environmental factors. The lack of homogeneity in the description of the disorders complicates the search for etiological factors. The main goal of this study is to verify the effect of age at onset of several symptoms in the clinical characteristics of Axis I psychiatric disorders in the trajectory of OCD patients. Methodology: 1,001 consecutive OCD patients were evaluated at a single time point. Standardized instruments were used: Structured Clinical Interview for Diagnosis of Axis I, according to DSM-IV and for impulse-control disorders; Yale-Brown Obsessive-Compulsive Scale, Dimensional Yale-Brown Obsessive-Compulsive Scale, Beck Depression and Anxiety Inventories and Brown Beliefs assessment Scale; and the Natural History Questionnaire. Chi-square test was used for categorical variables, and Kruskal-Wallis and ANOVA tests were used for continuous variables. For all the tests the significant level was considered p <.05. To analyze the distribution of comorbidities according to age at onset a Bayesian approach was used. Results: Patients with early age at onset had higher frequency of separation anxiety disorder (p<0.001), attention deficit hyperactivity disorder (ADHD) (p=0.031); tic disorders (p<0.009); obsessive-compulsive spectrum disorders (p<0.001); impulse-control disorders (p=0.005) and mood disorders (p=0.020). Besides, they presented higher severity of all measures of Y-BOCS score (p<0.001) and DY-BOCS score (p<0.001), OCD course with progressive worsening (p<0.001) and higher frequency of family history of OCD (p<0.001) and tic disorders (p=0.013). OCD patients who presented separation anxiety disorder as the first manifested diagnosis had higher frequencies of: anxiety disorders (p=0.058), somatoform disorders (p=0.056), post-traumatic stress disorder (p=0.004), higher frequency of Sexual/Religious dimension (p=0.053) and higher scores on Beck depression (p=0.005) and Beck anxiety (p<0.001). OCD patients who presented ADHD as first manifested diagnosis presented higher frequency of substance abuse (p<0.001) and presented more OCD course with progressive worsening (p=0.033). OCD patients who presented tic disorder as first manifested diagnosis presented higher frequency of OC spectrum disorders (p=0.034). Conclusion: We can conclude that OCD is a heterogeneous disorder and may include several subtypes according to the chosen approac
