Estudo sobre o insight em pessoas com psicose

Para além das variáveis clínicas e sociodemográficas existem concerteza importantes componentes individuais que desempenham um contributo importante no nível de insight apresentado por cada pessoa doente, por exemplo, o nível de inteligência, personalidade, cultura, experiências passadas, memória, etc. A natureza clínica, emocional e/ou intelectual do termo ajuda-nos a compreender a complexidade da dificuldade que existe na sua tradução e, inclusive, na sua compreensão. Daí que as definições atribuídas ao conceito sejam muito distintas e variem consoante a formação teórica do autor/investigador. Pretende-se, a partir dessa identificação/compreensão, promover a qualidade de vida destas pessoas através do desenvolvimento de novas aprendizagens que possibilitem uma cooperação activa. É igualmente fundamental ir ao encontro das capacidade intactas de maneira a possibilitar a aquisição de novos(s) comportamento(s) que tenham um impacte positivo nas queixas, sinais, sintomas, incapacidade e disfuncionalidade apresentados pelo/a utente. Uma vez que a própria conceptualização do termo traduzirá aquilo que se pretende avaliar,será efectuada uma reflexão detalhada acerca dos instrumentos e definições que têm sido mais utilizadas para explorar o insight nas psicoses.Procurei, no meu trabalho de investigação, realçar e promover a importância que cada sujeito, alvo de intervenção, desempenha ao longo do seu processo de recuperação e na prevenção de recaídas. No seguimento dos objectivos acima descritos, para além da revisão teórica efectuada ao fenómeno em termos de conceptualização e estudos desenvolvidos na área de investigação, foi,neste estudo, realizada a contribuição para a validação do instrumento “Assessment of Insight in Psychosis: a re-standartization of a New Scale” de Marková & Berrios (2003).O fenómeno de insight escolhido pela Insight Scale, relata menos as mudanças vividas em relação à doença mental, e mais a actual consciência e articulação de tais mudanças. Tendo como base uma abordagem psicopedagógica, o fenómeno do insight aqui explorado assentou numa perspectiva reabilitativa, actual e multidimensional, que fosse para além das dimensões clínicas tradicionais. Neste sentido é apresentada uma escala original, intitulada “Escala de Avaliação do Insight e Identificação das Necessidades em Pessoas com Psicose”, bem como um modelo de intervenção psicopedagógico breve, assente nos pressupostos descritos ao longo do trabalho.-----------------------------------------ABSTRACT: The importance of insight in people with mental illnesses was first studied in psychiatry, in the first decades of the 20th century, by people as important as Lewis (1934) and Jaspers (1959). However, this field of investigation was left unexplored for many years. Only in the last decade has this phenomenon become the object of numerous scientific investigations, having been given special attention by its investigators. For this reason a significant number of instruments for evalauting insight in psychotic disorders were developed. Since then many papers have been published, which has allowed for a more in depth knowledge on the subject. Therefore, in recent years, the concept of insight has been developed in an attempt to clarify its compexity. A once dichotomic phenomenon, described in terms of presence or absence, became considered multidimensional, which made the identification of different levels of insight and different dimensions possible. Current concepts categorize insight into five dimensions: the awareness of the patient in relation to his/her mental illness, the awareness of the patient in relation to the social consequences of his/her illness, the awareness of the need for treatment, the awareness of the symptoms and the explanation of those symptoms in relation to the illness. The lack of insight in psychiatry, in general terms, and as this phenomenon has been described, the lack of awareness of having a mental illness, represents one of the most common symptoms of schizophrenia and affects a big part of the population that suffer from this illness. It is estimated that bewteen 50 and 80 per cent of patients with schizophrenia do not believe that they are ill, which, consequently has a big impact in the process of adherence to treatment. It is still not possible, however, to identify all the factors that determine the lack of insight in schizophrenics. There are psychological, social and cultural influences that almost certainly play their role in the lack of insight registered in this pathology.Since the impact of scizophrenia is felt in many aspects of the individual’s life, its effective treatment should be directed at various levels, including the improvement of insight. One of the objectives of this study is to explore the relationship between the level of insight in psychosis and the clinical and sociodemographic variables, the psychopathology and its global functioning. As well as the clinical and sociodemographic variables, there are of course important individual components that contribute to the level of insight seen in each patient, for example, their level of inteligence, personality, culture, past experiences, memory, etc. The clinical, emotional and/or intelectual nature of the term helps us understand the difficulty that lies in its interpretation as well as in its comprehension. Therefore, the definitions attributed to the term are very different and vary according to the theoretical training of the investigator. It is intended, from this identification/understanding, to promote the quality of life of these people through the development of new findings that might enable an active cooperation. It is equally fundamental to observe their unimpaired capacities in order to enable the acquisition of new behaviour(s) that have a positive impact on the complaints, signs, symptoms, incapacity and disfunctioning seen in the patient.As the actual comprehension of the term explains what we intend to evaluate, a detailed reflection is made on the instruments and definitions that have been used the most to explore insight in psychosis.In this investigation I tried to underline and promote the importance that each subject, undergoing medical intervention, plays during his/her process of recovery and prevention of relapses. Considering the above mentioned objectives, as well as a theoretical review of the phenomenon in terms of conceptualization and investigative studies developed, this study contributed to the validation of the instrument.The insight phenomenon chosen by the “Insight Scale”, records less changes experienced in relation to the mental illness and more actual awareness and articulation of these changes. Based on a psychopedagogical approach, the insight phenomenon explored here settled on a rehabilitation, current and multidimensional perspective that would go beyond the traditional clinical dimensions. For this reason an original scale entitled “Insight Evaluation Scale and Need Identification in Psychosis Patients” is presented, as well as a psychopedagogical intervention model soon to be used with admitted patients based on the presuppositions described in this study.

What is the shape of an air bubble on a liquid surface?

We have calculated the equilibrium shape of the axially symmetric meniscus along which a spherical bubble contacts a flat liquid surface by analytically integrating the Young-Laplace equation in the presence of gravity, in the limit of large Bond numbers. This method has the advantage that it provides semianalytical expressions for key geometrical properties of the bubble in terms of the Bond number. Results are in good overall agreement with experimental data and are consistent with fully numerical (Surface Evolver) calculations. In particular, we are able to describe how the bubble shape changes from hemispherical, with a flat, shallow bottom, to lenticular, with a deeper, curved bottom, as the Bond number is decreased.

Reversible current power supply for fast-field cycling nuclear magnetic resonance equipment

The Fast Field-Cycling Nuclear Magnetic Resonance (FFC-NMR) is a technique used to study the molecular dynamics of different types of materials. The main elements of this equipment are a magnet and its power supply. The magnet used as reference in this work is basically a ferromagnetic core with two sets of coils and an air-gap where the materials' sample is placed. The power supply should supply the magnet being the magnet current controlled in order to perform cycles. One of the technical issues of this type of solution is the compensation of the non-linearities associated to the magnetic characteristic of the magnet and to parasitic magnetic fields. To overcome this problem, this paper describes and discusses a solution for the FFC-NMR power supply based on a four quadrant DC/DC converter.

Layerwise mixed models for analysis of multilayered piezoelectric composite plates using least-squares formulation

This work provides an assessment of layerwise mixed models using least-squares formulation for the coupled electromechanical static analysis of multilayered plates. In agreement with three-dimensional (3D) exact solutions, due to compatibility and equilibrium conditions at the layers interfaces, certain mechanical and electrical variables must fulfill interlaminar C-0 continuity, namely: displacements, in-plane strains, transverse stresses, electric potential, in-plane electric field components and transverse electric displacement (if no potential is imposed between layers). Hence, two layerwise mixed least-squares models are here investigated, with two different sets of chosen independent variables: Model A, developed earlier, fulfills a priori the interiaminar C-0 continuity of all those aforementioned variables, taken as independent variables; Model B, here newly developed, rather reduces the number of independent variables, but also fulfills a priori the interlaminar C-0 continuity of displacements, transverse stresses, electric potential and transverse electric displacement, taken as independent variables. The predictive capabilities of both models are assessed by comparison with 3D exact solutions, considering multilayered piezoelectric composite plates of different aspect ratios, under an applied transverse load or surface potential. It is shown that both models are able to predict an accurate quasi-3D description of the static electromechanical analysis of multilayered plates for all aspect ratios.

A many-core co-processor for embedded parallel computing on FPGA

Single processor architectures are unable to provide the required performance of high performance embedded systems. Parallel processing based on general-purpose processors can achieve these performances with a considerable increase of required resources. However, in many cases, simplified optimized parallel cores can be used instead of general-purpose processors achieving better performance at lower resource utilization. In this paper, we propose a configurable many-core architecture to serve as a co-processor for high-performance embedded computing on Field-Programmable Gate Arrays. The architecture consists of an array of configurable simple cores with support for floating-point operations interconnected with a configurable interconnection network. For each core it is possible to configure the size of the internal memory, the supported operations and number of interfacing ports. The architecture was tested in a ZYNQ-7020 FPGA in the execution of several parallel algorithms. The results show that the proposed many-core architecture achieves better performance than that achieved with a parallel generalpurpose processor and that up to 32 floating-point cores can be implemented in a ZYNQ-7020 SoC FPGA.

System-on-chip field-programmable gate array design for onboard real-time hyperspectral unmixing

Hyperspectral instruments have been incorporated in satellite missions, providing large amounts of data of high spectral resolution of the Earth surface. This data can be used in remote sensing applications that often require a real-time or near-real-time response. To avoid delays between hyperspectral image acquisition and its interpretation, the last usually done on a ground station, onboard systems have emerged to process data, reducing the volume of information to transfer from the satellite to the ground station. For this purpose, compact reconfigurable hardware modules, such as field-programmable gate arrays (FPGAs), are widely used. This paper proposes an FPGA-based architecture for hyperspectral unmixing. This method based on the vertex component analysis (VCA) and it works without a dimensionality reduction preprocessing step. The architecture has been designed for a low-cost Xilinx Zynq board with a Zynq-7020 system-on-chip FPGA-based on the Artix-7 FPGA programmable logic and tested using real hyperspectral data. Experimental results indicate that the proposed implementation can achieve real-time processing, while maintaining the methods accuracy, which indicate the potential of the proposed platform to implement high-performance, low-cost embedded systems, opening perspectives for onboard hyperspectral image processing.

Production of Shistosoma mansoni cercariae by Biomphalaria glabrata from a focus in Belo Horizonte, Minas Gerais

The snail density, levels of infection and the monthly production of Schistosoma mansoni cercariae by Biomphalaria glabrata were determined in a focus of Barreiro de Baixo (Belo Horizonte, MG, Brazil). During a period of 38 months (1984 to 1987) 5,366 snails were collected of which 324 (6.03%) were infected with S. mansoni. The total number of cercariae shed was 5,667,312. Each snail shed an average of 17,422 cercariae during the time that it was under study in the laboratory. The greatest longevity of infected snails was 218 days. Natural cure was observed in 42 (12.9%) of the infected specimens about 130 days after collection. The average snail density in the focus during the period of study was 16.3 snails per scoop. The shedding of cercariae by snails collected from the field was compared with laboratory bred specimens infected in mass with the LE strain of S. mansoni from Belo Horizonte. The laboratory infected snails shed an average of 6,061 cercariae each, a value 2.8 times less than the field specimens due to a shorter life span. The prevalence of schistosomiasis in the focus was 14.3%.
