Tomada de decisão de Psicólogos em avaliação Psicologica

Psychological assessment is a procedure that is inserted in all areas of a psychologist s professional field of work. When starting any psychological intervention, it is necessary to carry an analysis of how individual operate in order to identify and define their demands to adequately meet them. It is important to study this practice because the choice of instruments, techniques and procedures to be employed influences the efficiency and effectiveness of the work and the image of the profession towards society in general, also impacting the scientific community. This study aimed to identify, in the subjects, the percentage of professionals in psychology who make use of the Psychological Assessment in the Northeastern region of Brazil; another objectives were to analyze the profile of these professionals in terms of gender, time after graduation, additional training in PA, the state of the country where he/she works; to check how psychologists do their planning when using PA as well as to identify which differences can be observed in terms of time from graduation and additional training in the process of planning the assessment different extents. The instrument used was an online questionnaire and the sample was by adhesion to the application. The attendance was of 159 professionals and most of them were females with a specialist degree. It was found that the majority of the professionals perform the planning of the PA, establishing a method and choosing the most appropriate strategies to be used. It was also verified that most of the subjects fulfill the steps of the whole process, and when planning the techniques of data collection, integrating database from different sources, reporting the results and returning the information, the professional demonstrates his/her goals to understand their demands and accomplish the decision making and/or proposed intervention for individuals assessed. It was found that the undergraduate degree may not have produced a more complete effect in the professional qualification and therefore, of the quality of the actions in PA, and that there is a need for training and continuing education

Variação da pressão sistólica como indicadora precoce de hipovolemia e guia de reposição volêmica com solução hiperosmótica e hiperoncótica no cão

JUSTIFICATIVA E OBJETIVOS: Estudos introduziram novo método para avaliação da pré-carga, baseado na análise da variação da pressão sistólica (VPS) durante ventilação artificial. O objetivo desta pesquisa é avaliar se a VPS e sua derivada delta down (ddown) são indicadoras precoces de hipovolemia e guias de reposição volêmica com solução hiperosmótica e hiperoncótica. MÉTODO: Doze cães foram submetidos a sangramentos parciais de 5% da volemia até se atingir 20% da volemia (14 ml.kg-1). Antes (controle) e após cada sangramento foram realizadas análises hemodinâmicas, respiratórias e sangüíneas. Após, os cães foram submetidos à reposição com solução de NaCl a 7,5% em dextran 70 a 3,75% (SHD) (4 ml.kg-1) e novas análises dos atributos estudados foram realizadas aos 5 e 30 minutos após a reposição. RESULTADOS: A pressão arterial média diminuiu durante o sangramento e aumentou após a reposição, sem retornar aos valores do controle. As pressões da artéria pulmonar e do átrio direito (PAD) diminuíram antes e aumentaram após a reposição para valores semelhantes aos do controle. A pressão da artéria pulmonar ocluída (PAPO) diminuiu após o primeiro sangramento e manteve-se em valores abaixo aos do controle, mesmo após a reposição. O índice cardíaco não se alterou, mas aumentou após a reposição, para valores superiores aos do controle. O índice sistólico (IS) diminuiu antes e aumentou após a reposição, em níveis superiores aos do controle. Os índices de resistência vascular sistêmica (IRVS) e pulmonar (IRVP) não se alteraram antes, mas diminuíram após a reposição, com o IRVS em níveis inferiores aos do controle, e o IRVP em níveis semelhantes aos do controle. Os índices de trabalho sistólico dos ventrículos direito (ITSVD) e esquerdo (ITSVE) diminuíram durante o sangramento, mas aumentaram após a reposição, com o ITSVD em níveis superiores aos do controle e o ITSVE em níveis semelhantes aos do controle. A VPS e ddown aumentaram progressivamente durante o sangramento e diminuíram após a reposição, mas mantendo-se em valores superiores aos do controle. As maiores correlações de VPS e ddown foram com IS, PAPO, PAD e ITSVE. CONCLUSÕES: No cão, nas condições empregadas, a VPS e sua derivada ddown são indicadoras precoces de hipovolemia e guias sensíveis de reposição volêmica com SHD.

Algoritmo treansgenético na solução do problema do Caixeiro Viajante

The Traveling Purchaser Problem is a variant of the Traveling Salesman Problem, where there is a set of markets and a set of products. Each product is available on a subset of markets and its unit cost depends on the market where it is available. The objective is to buy all the products, departing and returning to a domicile, at the least possible cost defined as the summation of the weights of the edges in the tour and the cost paid to acquire the products. A Transgenetic Algorithm, an evolutionary algorithm with basis on endosymbiosis, is applied to the Capacited and Uncapacited versions of this problem. Evolution in Transgenetic Algorithms is simulated with the interaction and information sharing between populations of individuals from distinct species. The computational results show that this is a very effective approach for the TPP regarding solution quality and runtime. Seventeen and nine new best results are presented for instances of the capacited and uncapacited versions, respectively

Impacto do racionamento nos resultados das empresas concessionárias do serviço público de distribuição de energia elétrica: um estudo nas empresas privadas da Região Nordeste

This work verifies the impact caused by the Emergencial Program of Reduction of Consumption of Electric Energy (energy-rationing program) in the results of the concessionary private companies of the public service of electric energy distribution localized in the Northeast Area. As the rationing invigorated from June 2001 to February 2002, its effects are diluted in the results presented by these companies in the second semester of 2001 and first quarter of 2002, with prominence for the last quarter of 2001, when the revenue of extraordinary tariff restore was instituted by the National Agency of Electric Energy (ANEEL), consequence of the so-called General Agreement of the Electric Sector made between the federal government and the companies of the electric sector. The structure of a generic electric sector and a historical review of the Brazilian electric sector from the time it was controlled by the private enterprises, including the State control period, about 1960, and returning to the control of the private enterprises in 1990, under a new regulation structure are presented. An explanation of the models of economic regulation that Brazil used for the electric sector is made, with prominence for the price cap that is the actual effective model. The process of tariff revision foreseen in the concession contracts signed by the federal government and the concessionary companies is presented, highlighting its two stages: the tariff rebalancing that defines the new price cap and the calculation of the factor X that establishes the efficiency goals for the companies. There is made a presentation of the Emergencial Program of Reduction of Consumption of Electric Energy and of the consequent General Agreement of the Electric Sector, which created the revenue of extraordinary tariff restore. A conceptual revision on reviews is presented, regarding to concepts, accomplishment and recognition. A brief review of the six companies that made part of the worked sample is also presented. Analyzing the quarters historical review and of amount of sold energy, it was possible to conclude that the energy-rationing altered the results of the studied companies significantly and that alteration was masked by the accounting process of the revenue of extraordinary tariff restore

Hematological changes in sheep inoculated with natural and Cobalt60-irradiated Crotalus durissus terrificus venom (Laurenti, 1768)

Natural (NV) and Cobalto60-irradiated (IrV) Crotalus durissus terrificus venom were used to evaluate serum production capacity of sheep and possible hematological and biochemical effects. Freeze-dried venom aliquots were diluted in acidified saline solution (NaCl 150 mM, pH 3.0) and irradiated by a Cobalt 60 source at a dose of 5.54 x 102 Gy/h and a concentration of 2.000 Gy. Twelve sheep were divided into two groups of six animals. One group received irradiated venom (IrV) and the other natural venom (NV). Three antigen doses (venom) were administered at monthly intervals. Blood samples were collected weekly for analysis of serum neutralization potency and capacity, complete blood count (CBC), total plasma protein, fibrinogen, albumin, and globulin. At the end of the experiment, the animals were challenged with a LD50 for sheep and showed no signs of envenoming. The two groups did not present clinical alterations. Results of the total leukocyte count did not present interaction or time factor effect for both groups, but there was a different action between them, with the NV group presenting more cells than the IrV group. The leukocyte increase to 13,000/ml indicates that slight leukocytosis occurred in the week after the first inoculation in the NV group. There was no statistically significant difference between groups in the absolute count of segmented neutrophils, eosinophils, and lymphocytes but there were statistically significant oscillations in values at the different collecting times. The NV group presented an increase in the absolute neutrophil count after the first inoculation that persisted for 5 weeks. In the IrV group, the increase in neutrophils occurred only in the first week returning to normal in the following weeks. The alterations in the neutrophil count are indicative of systemic inflammatory response related to cytokine release; response was more marked in the NV group, showing its greater toxicity.

Bone mineral density of tibae and femura of broiler breeders: growth, development and production

The aim of this study was to follow-up the physiological variations in the development of the bone tissue, associating them with the egg production curve. This study was carried out in the facilities of the Faculdade de Medicina Veterinária e Zootecnia of the UNESP, Botucatu, Brazil. Twenty-three families of Ross broiler breeders were used, each family consisting of 13 females and 1 male, distributed in 23 pens of 5.0m² each. The management was that recommended by the genetic company manual (Agroceres Ross, 2003), with daily feeding until 6th week of age; and birds were fed according to a 5:2 schedule (5 days fed, 2 days of fasting) between 7 and 17 weeks of age, returning to daily feeding starting at 18 weeks of age. Birds did not receive afternoon calcium supplementation. on the fourth week of rearing, 84 females were removed for bone analyses of the right tibia and femur, using optical densitometry in radiographic images technique. These analyses were sequentially carried out in 4, 8, 12, 15, 20, 24, 30, 35, 42, 47, and 52 week-old birds. The egg production curve of the birds was followed-up and associated to bone mineral density results. For bone mineral density evaluation (BMD) birds were divided by weight categories as light, intermediate, or heavy within each data age. BMD values of the tibias were not influenced by weight range, but by the age at collection. on the other hand, interactions were found among femur BMD values and weight and age categories. There was no correlation between eggshell quality and femur BMD. A negative correlation (-0.15) was observed between tibia BMD and eggshell percentage. It was possible to conclude that the egg production has little influence on bone mineral density of the birds probably because there was no need of bone mineral mobilization during the production period, since the observed egg production was below that observed under commercial conditions.

Urinary fluoride output in children following the use of a dual-fluoride varnish formulation

Objective: This study evaluated the bioavailability of fluoride after topical application of a dual-fluoride varnish commercially available in Brazil, when compared to Duraphat T. Material and methods: The urinary fluoride output was evaluated in seven 5-year-old children after application of the fluoride varnishes, in two different phases. In the first phase (I), children received topical application of the fluoride varnish Duofluorid XII (2.92% fluorine, calcium fluoride + 2.71% fluorine, sodium fluoride, FGM (TM)). After 1-month interval (phase II), the same amount (0.2 mL) of the fluoride varnish Duraphat (2.26% fluorine, sodium fluoride, Colgate T) was applied. Before each application all the volunteers brushed their teeth with placebo dentifrice for 7 days. Urinary collections were carried out 24 h prior up to 48 h after the applications. Fluoride intake from the diet was also estimated. Fluoride concentration in diet samples and urine was analyzed with the fluoride ion-specific electrode and a miniature calomel reference electrode coupled to a potentiometer. Data were tested by ANOVA and Tukey's post hoc test (p < 0.05). Results: There were significant differences in the urinary fluoride output between phases I and II. The use of Duofluorid XII did not significantly increase the urinary fluoride output, when compared to baseline levels. The application of Duraphat caused a transitory increase in the urinary fluoride output, returning to baseline levels 48 h after its use. Conclusions: The tested varnish formulation, which has been shown to be effective in in vitro studies, also can be considered safe.

Efeitos cardiovasculares de duas doses de dexmedetomidina: estudo experimental em cães

JUSTIFICATIVA E OBJETIVOS: A dexmedetomidina é um novo agonista alfa2-adrenérgico, havendo, atualmente, crescente interesse no seu uso em Anestesiologia, por reduzir o consumo de anestésicos e promover estabilidade hemodinâmica. O objetivo desta pesquisa foi estudar os efeitos cardiovasculares da dexmedetomidina no cão anestesiado, empregando-se duas doses distintas e semelhantes àquelas utilizadas em Anestesiologia. MÉTODO: 36 cães adultos anestesiados com propofol, fentanil e isoflurano foram divididos em três grupos: G1, injeção de 20 ml de solução de cloreto de sódio a 0,9%, em 10 minutos, seguida de injeção de 20 ml da mesma solução, em 1 hora; G2, injeção de 20 ml de solução de cloreto de sódio a 0,9% contendo dexmedetomidina (1 µg.kg-1), em 10 minutos, seguida de injeção de 20 ml da mesma solução, em 1 hora e G3, injeção de 20 ml de solução de cloreto de sódio a 0,9% contendo dexmedetomidina (2 µg.kg-1) em 10 minutos, seguida de injeção de 20 ml da mesma solução, em 1 hora. Estudaram-se os atributos cardiovasculares em quatro momentos: M1, controle; M2, após a injeção inicial de 20 ml da solução em estudo, em 10 minutos, coincidindo com o início da injeção da mesma solução, em 1 hora; M3, 60 minutos após M2 e M4, 60 minutos após M3. RESULTADOS: A freqüência cardíaca (FC) diminuiu no G2, no M2, retornando aos valores basais no M3, enquanto no G3 diminuiu no M2, mantendo-se baixa durante todo o experimento. No G1 houve aumento progressivo da FC. em nenhum grupo houve alteração da pressão arterial. A resistência vascular sistêmica (RVS) manteve-se estável no G2 e G3, enquanto no G1 apresentou redução em M2, mantendo-se baixa ao longo do experimento. O índice cardíaco (IC) não apresentou alterações significativas no G2 e G3, mas aumentou progressivamente no G1. CONCLUSÕES: Conclui-se que no cão, nas condições experimentais empregadas, a dexmedetomidina diminui a FC de forma dose-dependente, inibe a redução da RVS produzida pelo isoflurano e impede a ocorrência de resposta hiperdinâmica durante o experimento.

Orientação espacial em adultos com deficiência visual: efeitos de um treinamento de navegação

O objetivo deste estudo foi demonstrar se um programa de navegação pode ajudar indivíduos com deficiência visual a melhorar a acurácia na orientação dinâmica. Nove participantes com deficiência visual retornaram a um ponto de partida após percorrer rotas em linha reta e triangular. Pré e pós-avaliações foram feitas entre um período de 4 meses, durante o qual o treinamento com navegação foi realizado. Entre pré e pós-teste, erros relativos de desvios angulares (ERDA) foram diferentes apenas na tarefa em linha reta. O valor de ERDA foi maior na tarefa em linha reta possivelmente por causa da magnitude do giro inicial antes de retornar ao ponto de partida (i.e., 180º) em contraste com a tarefa triângulo (i.e., 45º). Conclui-se que, em tarefas de orientação, os erros no desvio angular dependem da amplitude do giro inicial ao retornar para o ponto de partida. Ainda, a acurácia na manutenção da direção é influenciada por um treinamento específico com navegação.

Treino musical e capacidade da memória operacional em crianças iniciantes, veteranas e sem conhecimentos musicais

A memória operacional e a atividade musical ativam áreas encefálicas recíprocas e homólogas, contudo não há evidências se o treino musical pode ampliar a capacidade da memória operacional. Objetivo: Avaliar o desempenho do treino musical sob a memória operacional em crianças de 9 e 10 anos de idade, praticantes de treino musical e sem experiência musical. PARTICIPANTES: Crianças Iniciantes (n=20), Veteranas (n=20) e Grupo Controle (n=20). MATERIAIS: Instrumentos computadorizados para avaliação da memória operacional. RESULTADOS: Crianças veteranas apresentaram melhores pontuações no BCPR (Teste de Repetição de Pseudopalavras para crianças brasileiras) e em subtestes da AWMA (Avaliação Automatizada da Memória Operacional). CONCLUSÃO: O treino musical parece ter contribuído para o desenvolvimento da memória operacional em crianças veteranas no programa de treino musical.

Um transtorno delirante somático atípico

This paper describes the case of a 38 year-old single man with a previous history of social phobia and alcoholism, who presented an unusual pathological belief during the last 9 years. He believe that the muscles of his arms were loose, separated from the bones, and that a green fluid flowed from his shoulders, running under the skin towards his fingers, and returning to the shoulders. He also reported pain, weakness and sensations of loose and fluffy muscles, besides having visual and kinesthetic hallucinations and judgement impairment. No other psychopathological manifestations were observed. There was a worsening of the complaints and depressive symptoms with the use of pimozide and no improvement with fluoxetine, venlafaxine or risperidone. He is presently taking sulpiride. Psychopathological issues and difficulties in diagnosis and treatment are discussed.

Effect of fish density during transportation on stress and mortality of juvenile Tambaqui Colossoma macropomum

The increased demand for juvenile tambaqui Colossoma macropomum for grow-out ponds and stocking programs in the Amazon state of Brazil has increased the transportation of this species. This study was designed to determine the optimum density of juvenile tambaqui during transportation in closed containers. Fish (51.9 ± 3.3 g and 14.9 ± 0.4 cm) were packed in sealed plastic bags and transported for 10 h at four densities: 78, 156, 234, and 312 kg/m3. After transportation, fish from each density were kept in separate 500-L tanks for 96 h. Mortality, 96-h cumulative mortality, water quality, and blood parameters (hematocrit, plasma cortisol, and glucose) were monitored. Fish mortality after transportation was significantly lower at densities of 78 and 156 kg/m3 than at 234 and 312 kg/m3. Cumulative mortality was significantly lower at a density of 78 kg/m3. Dissolved oxygen after 10 h of transportation remained high at a density of 78 kg/m3, but reached critically low values at all other densities. Ammonia concentration was highest at the lowest density and was lower at higher densities. Carbon dioxide concentration was lowest at the density of 78 kg/m3 but higher in the other treatments. Plasma glucose and cortisol increased significantly immediately after transportation at densities of 156, 234, and 312 kg/m3, returning to control values by 24 h. The best density for juvenile tambaqui during a 10-h transportation haul in a closed container was 78 kg/m3. At this density there was no fish mortality, water quality was kept within acceptable values, and fish were not stressed.
