Adicionando a entrevista motivacional e o mapeamento cognitivo à terapia cognitivo-comportamental em grupo: resultados de um ensaio clínico randomizado

OBJECTIVE: Recent factor-analytic studies of obsessive-compulsive disorder identified consistent symptom dimensions. This study was designed in order to observe which obsessive compulsive symptom dimensions could be changed by adding two individual sessions of motivational interviewing and thought mapping of cognitive-behavioral group therapy using a randomized clinical trial. METHOD: Forty outpatients with a primary diagnosis of obsessive-compulsive disorder were randomly assigned to receive cognitive-behavioral group therapy (control group) or motivational interviewing+thought mapping plus cognitive-behavioral group therapy. To evaluate changes in symptomdimensions, the Dimensional Yale-Brown Obsessive-Compulsive Scale was administered at baseline and after treatment. RESULTS: At post-treatment, there were statistically significant differences between cognitive-behavioral group therapy and motivational interviewing+thought mapping+cognitivebehavioral group therapy groups in the mean total Dimensional Yale-Brown Obsessive-Compulsive Scale score, and in the contamination and aggression dimension score. Hoarding showed a statistical trend towards improvement. CONCLUSION: These findings suggest that adding motivational interviewing+thought mapping to cognitive-behavioral group therapy can facilitate changes and bring about a decrease in the scores in different obsessive-compulsive disorder symptom dimensions, as measured by the Dimensional Yale-Brown Obsessive-Compulsive Scale. Nonetheless, additional trials are needed to confirm these results.OBJETIVO: Recentes estudos utilizando análise fatorial no transtorno obsessivocompulsivo identificaram dimensões consistentes dos sintomas. Este estudo foi delineado para observar quais dimensões dos sintomas obsessivo-compulsivos podem ser modificadas adicionando duas sessões individuais de entrevista motivacional e mapeamento cognitivo à terapia cognitivo-comportamental em grupo usando um ensaio clínico randomizado. MÉTODO: Quarenta pacientes ambulatoriais com diagnóstico primário de transtorno obsessivo-compulsivo foram alocados aleatoriamente para receber terapia cognitivo-comportamental em grupo (grupo controle) ou entrevista motivacional+mapeamento cognitivo+terapia cognitivo-comportamental em grupo. Para avaliar mudanças nas dimensões dos sintomas, foi administrada a Escala Dimensional para Sintomas Obsessivo-Compulsivos de Yale-Brown antes do início e após o tratamento. RESULTADOS: Ao final do tratamento houve diferença estatisticamente significativa entre a terapia cognitivo-comportamental em grupo e entrevista motivacional+mapeamento cognitivo+terapia cognitivocomportamental em grupo na média do escore total da Escala Dimensional para Sintomas Obsessivo-Compulsivos de Yale-Brown e no escore da dimensão de contaminação e agressão. Colecionismo apresentou melhora com tendência estatística. CONCLUSÃO: Esses achados sugerem que acrescentar entrevista motivacional+mapeamento cognitivo à terapia cognitivo-comportamental em grupo pode facilitar mudanças na redução dos escores nas diferentes dimensões dos sintomas, como indicado pela Escala Dimensional para Sintomas Obsessivo-Compulsivos de Yale-Brown. No entanto, são necessários estudos adicionais para confirmar estes resultados.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPQ)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

A visão dos professores quanto ao processo de ensino e de aprendizagem do Basquetebol nas aulas de Educação Física: A realidade de Volta Redonda/RJ

A presente pesquisa teve como objetivo geral investigar a visão dos professores acerca do processo de ensino e de aprendizagem do basquetebol nas aulas de Educação Física em ambiente escolar. Participaram da pesquisa docentes das instituições públicas e privadas do município de Volta Redonda/RJ/Brasil em turmas do 6º ao 9º ano do ensino fundamental. Tratou-se de um estudo quanti-qualitativo com análise de conteúdo e, como procedimento de coleta de dados, foram entrevistados sessenta docentes que opinaram acerca da questão investigada. Verificou-se a realidade do desenvolvimento do basquetebol não somente na condição de conteúdo das aulas da Educação Física, mas também numa dimensão que transpõe os limites escolares, onde o esporte representa significativo papel na sociedade. Ações conjuntas no sentido de oportunizar o crescimento do basquetebol como conteúdo das aulas de Educação Física podem representar um caminho para a descrição da sua aplicação em todos os contextos, embora não se deva abrir mão da relevância da disciplina no cenário escolar em favor da obtenção de resultados em competições esportivas

Internationale Beziehungen und Soziologie : das ‚Scharnier’ der Differenzierung

Meta-analysis of the heterogeneous symptoms of obsessive-compulsive disorder (OCD) has found a four-factor structure of symptom dimensions consisting of cleaning, forbidden thoughts, symmetry, and hoarding. Research into age of onset of symptom dimensions has yielded inconsistent results, and it is unknown whether symptoms along these dimensions differ in their clinical course. We assessed age of onset and clinical course of different OCD symptom dimensions in a large cohort of adult patients. Nine-hundred fifty-five subjects were assessed using the Dimensional Yale-Brown Obsessive-Compulsive Scale. For age of onset analysis, we tested across three methods of classification: (1) primary (more severe) symptom dimension (2) clinically significant symptoms within a dimension or (3) any symptoms within a dimension. Age of onset was defined as the earliest age of onset reported for any individual item within a symptom dimension. For analysis of different types of clinical course, we used chi-square tests to assess for differences between primary symptom dimensions. OCD symptoms in the symmetry dimension had an earlier age of onset than other OCD symptom dimensions. These findings remained significant across all three methods of classification and controlling for gender and comorbid tics. No significant differences were found between the other dimensions. Subjects with primary OCD symptoms in the forbidden thoughts dimension were more likely to report a waxing-and-waning course, whereas symmetry symptoms were less likely to be associated with a waxing-and-waning course. © 2013

Mechanical behaviour of corrugated laminates

The present research work intends to perform a wide set of structural analyses upon corrugated composite laminated panels and based on these analyses, to assess their mechanical response in correspondence to the constructive solutions, which may range from the composite materials selection to the geometrical features and other modelling parameters. To improve the mechanical performance of those panels one may consider enhancing their geometrical characteristics, their corrugation shape configuration and the materials used to build them. In this latter case, when considering materials selection, laminated composites may also constitute an important alternative. In any case it is considered necessary to assess the impact that each of these parameters may have in the static and in the free vibration behaviour of the structures, in a comprehensive and detailed way. To achieve the main objective of this research work, a comprehensive and diversified set of case studies is considered in order to characterize the influence that each of the modelling, material and geometrical parameters and characteristics may have in the mechanical response of a corrugated panel. This study allowed concluding that for the wide set of design parameters considered, the fibre orientation and corrugation parameters are the ones responsible for the majority of the significantly improved performances.info:eu-repo/semantics/publishedVersio

Early intervention for obsessive compulsive disorder : An expert consensus statement

© 2019 Elsevier B.V.and ECNP. All rights reserved.Obsessive-compulsive disorder (OCD) is common, emerges early in life and tends to run a chronic, impairing course. Despite the availability of effective treatments, the duration of untreated illness (DUI) is high (up to around 10 years in adults) and is associated with considerable suffering for the individual and their families. This consensus statement represents the views of an international group of expert clinicians, including child and adult psychiatrists, psychologists and neuroscientists, working both in high and low and middle income countries, as well as those with the experience of living with OCD. The statement draws together evidence from epidemiological, clinical, health economic and brain imaging studies documenting the negative impact associated with treatment delay on clinical outcomes, and supporting the importance of early clinical intervention. It draws parallels between OCD and other disorders for which early intervention is recognized as beneficial, such as psychotic disorders and impulsive-compulsive disorders associated with problematic usage of the Internet, for which early intervention may prevent the development of later addictive disorders. It also generates new heuristics for exploring the brain-based mechanisms moderating the ‘toxic’ effect of an extended DUI in OCD. The statement concludes that there is a global unmet need for early intervention services for OC related disorders to reduce the unnecessary suffering and costly disability associated with under-treatment. New clinical staging models for OCD that may be used to facilitate primary, secondary and tertiary prevention within this context are proposed.Peer reviewe

Treatments used for obsessive-compulsive disorder-An international perspective

© 2019 John Wiley & Sons, Ltd.OBJECTIVE: The objective of this study was to characterise international trends in the use of psychotropic medication, psychological therapies, and novel therapies used to treat obsessive-compulsive disorder (OCD). METHODS: Researchers in the field of OCD were invited to contribute summary statistics on the characteristics of their samples. Consistency of summary statistics across countries was evaluated. RESULTS: The study surveyed 19 expert centres from 15 countries (Argentina, Australia, Brazil, China, Germany, Greece, India, Italy, Japan, Mexico, Portugal, South Africa, Spain, the United Kingdom, and the United States) providing a total sample of 7,340 participants. Fluoxetine (n = 972; 13.2%) and fluvoxamine (n = 913; 12.4%) were the most commonly used selective serotonin reuptake inhibitor medications. Risperidone (n = 428; 7.3%) and aripiprazole (n = 415; 7.1%) were the most commonly used antipsychotic agents. Neurostimulation techniques such as transcranial magnetic stimulation, deep brain stimulation, gamma knife surgery, and psychosurgery were used in less than 1% of the sample. There was significant variation in the use and accessibility of exposure and response prevention for OCD. CONCLUSIONS: The variation between countries in treatments used for OCD needs further evaluation. Exposure and response prevention is not used as frequently as guidelines suggest and appears difficult to access in most countries. Updated treatment guidelines are recommended.Peer reviewe

Brain structural correlates of sensory phenomena in patients with obsessive-compulsive disorder

Background: sensory phenomena (SP) are uncomfortable feelings, including bodily sensations, sense of inner tension, 'just-right' perceptions, feelings of incompleteness, or 'urge-only' phenomena, which have been described to precede, trigger or accompany repetitive behaviours in individuals with obsessive-compulsive disorder (OCD). Sensory phenomena are also observed in individuals with tic disorders, and previous research suggests that sensorimotor cortex abnormalities underpin the presence of SP in such patients. However, to our knowledge, no studies have assessed the neural correlates of SP in patients with OCD. Methods: we assessed the presence of SP using the University of São Paulo Sensory Phenomena Scale in patients with OCD and healthy controls from specialized units in São Paulo, Brazil, and Barcelona. All participants underwent a structural magnetic resonance examination, and brain images were examined using DARTEL voxel-based morphometry. We evaluated grey matter volume differences between patients with and without SP and healthy controls within the sensorimotor and premotor cortices. Results: we included 106 patients with OCD and 87 controls in our study. Patients with SP (67% of the sample) showed grey matter volume increases in the left sensorimotor cortex in comparison to patients without SP and bilateral sensorimotor cortex grey matter volume increases in comparison to controls. No differences were observed between patients without SP and controls. Limitations: most patients were medicated. Participant recruitment and image acquisition were performed in 2 different centres. Conclusion: we have identified a structural correlate of SP in patients with OCD involving grey matter volume increases within the sensorimotor cortex; this finding is in agreement with those of tic disorder studies showing that abnormal activity and volume increases within this region are associated with the urges preceding tic onset

Toward identifying reproducible brain signatures of obsessive-compulsive profiles: rationale and methods for a new global initiative

Background Obsessive-compulsive disorder (OCD) has a lifetime prevalence of 2–3% and is a leading cause of global disability. Brain circuit abnormalities in individuals with OCD have been identified, but important knowledge gaps remain. The goal of the new global initiative described in this paper is to identify robust and reproducible brain signatures of measurable behaviors and clinical symptoms that are common in individuals with OCD. A global approach was chosen to accelerate discovery, to increase rigor and transparency, and to ensure generalizability of results. Methods We will study 250 medication-free adults with OCD, 100 unaffected adult siblings of individuals with OCD, and 250 healthy control subjects at five expert research sites across five countries (Brazil, India, Netherlands, South Africa, and the U.S.). All participants will receive clinical evaluation, neurocognitive assessment, and magnetic resonance imaging (MRI). The imaging will examine multiple brain circuits hypothesized to underlie OCD behaviors, focusing on morphometry (T1-weighted MRI), structural connectivity (Diffusion Tensor Imaging), and functional connectivity (resting-state fMRI). In addition to analyzing each imaging modality separately, we will also use multi-modal fusion with machine learning statistical methods in an attempt to derive imaging signatures that distinguish individuals with OCD from unaffected siblings and healthy controls (Aim #1). Then we will examine how these imaging signatures link to behavioral performance on neurocognitive tasks that probe these same circuits as well as to clinical profiles (Aim #2). Finally, we will explore how specific environmental features (childhood trauma, socioeconomic status, and religiosity) moderate these brain-behavior associations. Discussion Using harmonized methods for data collection and analysis, we will conduct the largest neurocognitive and multimodal-imaging study in medication-free subjects with OCD to date. By recruiting a large, ethno-culturally diverse sample, we will test whether there are robust biosignatures of core OCD features that transcend countries and cultures. If so, future studies can use these brain signatures to reveal trans-diagnostic disease dimensions, chart when these signatures arise during development, and identify treatments that target these circuit abnormalities directly. The long-term goal of this research is to change not only how we conceptualize OCD but also how we diagnose and treat it
