Clinical and non-clinical predictors of vocational recovery for Australians with psychotic disorders

Clinical and non-clinical predictors of vocational recovery were examined among 782 Australians diagnosed with DSM III R psychotic disorders, using data from the study on low-prevalence disorders, part of the National Survey of Mental Health and Wellbeing, Australia 1997-1998. Of the six significant clinical predictors, self-reported course of illness emerged as a potentially practical predictor of vocational recovery. Five non-clinical variables, age, education and skills, marital status, premorbid work adjustment, and use of a vocational service in the previous year, also contributed to the prediction of vocational recovery. The implications of these findings for both rehabilitation professionals and researchers are discussed.

Public policy and the prevention of substance-use disorders

Drug prevention has traditionally focused on influencing individual attitudes and behaviours. In particular, efforts have been directed towards adolescents in the school setting. However, evaluations of school-based drug education have identified limited success. There is increasing recognition that drug abuse is one of a number of risk behaviours, including truancy, delinquency and mental health problems, which share common antecedents that begin in the early years of childhood. Furthermore, these behaviours are shaped by macroenvironmental influences including the economic, social, cultural, and physical environment. Drug prevention needs to adopt a broader perspective: with greater collaboration in related programmes such as crime prevention and suicide prevention; with greater attention to the macroenvironmental influences on problem behaviours; and with greater attention to healthy development in the first years of childhood.

Alcohol and other drug use disorders among older-aged people

In Australia people aged 65 years or older currently comprise 12.1% of the population. This has been estimated to rise to 24.2% by 2051. Until recently there has been relatively little research on alcohol and other drug use disorders among these individuals but, given the ageing population, this issue is likely to become of increasing importance and prominence. Epidemiological research shows a strong age-related decline in the prevalence of alcohol and other drug use disorders with age. Possible reasons for this include: age-related declines in the use and misuse of alcohol and other drugs; increased mortality among those with a lifetime history of alcohol and other drug use disorders; historical differences in exposure to and use of alcohol and other drugs. Despite the age-related decline in the prevalence of these disorders, they do still occur among those aged 65 years or older and, given historical changes in exposure to and use of illicit drugs, it likely that the prevalence of these disorders among older-aged individuals will rise. Specific issues faced by older-aged individuals with alcohol and other drug use problems are discussed. These include: interactions with prescribed medications, under-recognition and treatment of alcohol and drug problems, unintentional injury and social isolation. Finally, a brief discussion of treatment issues is provided.

Will chymase inhibitors be the next major development for the treatment of cardiovascular disorders?

Chymase is contained in the secretory granules of mast cells. In addition to the synthesis of angiotensin II, chymase is involved in transforming growth factor-beta activation and cleaves Type I procollagen to produce collagen. NK301 and BCEAB are orally-active inhibitors of chymase. NK301 was tested in a dog model of vascular intimal hyperplasia after balloon injury and shown to reduce the increased chymase activity in the injured arteries and prevent intimal thickening. In a hamster model of cardiac fibrosis associated with cardiomyopathy, BCEAB reduced the increased cardiac chymase activity in cardiomyopathy and reduced fibrosis. Chymase inhibitors may be an important development for the treatment of cardiovascular injury associated with mast cell degranulation.

Alunos com paralisia cerebral na escola : linguagem, comunicação alternativa e processos de comunicativos

O estudo assume como problema de investigação analisar as contribuições da Comunicação Alternativa e Ampliada (CAA) aos processos comunicativos de alunos sem fala articulada no contexto da escola, destacando nesses processos o papel potencializador dos interlocutores. Fundamenta-se na abordagem de linguagem e na noção de enunciado discutidas por Bakhtin e nas contribuições de Vigotski sobre a relação entre desenvolvimento e aprendizagem, postulando que a aquisição e o desenvolvimento da linguagem ocorrem no curso das aprendizagens, ao longo da vida. As análises e reflexões empreendidas evidenciam uma discussão acerca da linguagem que se desloca da dimensão orgânica para a dimensão da constituição do sujeito como humano. Sob essa visão, outros conceitos, como os de língua, fala, interação verbal, dialogia, enunciação, aprendizagem e desenvolvimento são problematizados e também considerados como elementos fundantes e presentes nas relações comunicativas entre os sujeitos sem fala articulada e seus interlocutores. Na primeira etapa, o estudo busca conhecer as formas organizativo-pedagógicas de cinco Secretarias Municipais de Educação da Região Metropolitana de Vitória e da Secretaria de Estado da Educação no que diz respeito à identificação dos alunos com Paralisia Cerebral, sem fala articulada, ao acompanhamento técnico-pedagógico e à formação de professores que atuam na Educação Especial. Na segunda etapa, objetiva conhecer a processualidade da organização do trabalho pedagógico instituída nos contextos escolares e investiga os processos comunicativos em/com dois alunos com severos comprometimentos motores e de fala em duas escolas de Ensino Fundamental, localizadas no município de Serra e de Vitória. Nesta etapa, opta pela pesquisa- ação colaborativo-crítica por contribuir, teórica e metodologicamente, para sustentar os fazeres individuais e coletivos nos lócus de investigação. Os resultados revelam que, institucionalmente, ainda não se conhece quem são e quantos são os alunos com Paralisia Cerebral sem fala articulada no contexto de suas reais necessidades. Esse desconhecimento é atribuído pelas gestoras das Secretarias Municipais de Educação investigadas ao considerarem que, via de regra, são tomadas apenas as informações do Educacenso-INEP. As identificações pontuais, quando ocorrem, são decorrentes de estratégias internas adotadas, sendo uma delas o assessoramento pedagógico das equipes às escolas. No que tange ao ensino, à aprendizagem e à avaliação, o estudo constata que são atravessados por concepções equivocadas sobre os sujeitos com Paralisia Cerebral sustentadas, sobretudo, pela baixa expectativa e pelo pouco “esforço” quanto à sua escolarização. Constata também que o uso dos recursos de CAA potencializa os processos comunicativos dos alunos investigados e, movimentados pela linguagem, possibilita-lhes enunciar e fixar posições, opiniões e decisões, assegurando-lhes mais autonomia e fluidez do processo comunicacional. As formas de mediação dos interlocutores assim como as dinâmicas dialógicas por eles utilizadas com os alunos se constituem como elementos importantes nos processos de comunicação e interação. A espera do outro, o apoio e o incentivo à reformulação daquilo que se quer expressar, as modificações e alterações no jogo dialógico são exemplos dessa mediação. Quanto às ações de reorganização do trabalho pedagógico, o estudo registra maior articulação e colaboração entre professores da classe, professora da Educação Especial e estagiária no planejamento das aulas, dos conteúdos, com a inserção no notebook para um dos alunos; o uso das pranchas de comunicação, por ambos os alunos e seus interlocutores, como ação inovadora nos contextos escolares; a realização de atividades pelos alunos, com gradativa autonomia, a partir da disponibilização de recursos de TA/CAA (pasta de conteúdos temáticos, figuras imantadas, quadro metálico, ponteira, plano inclinado, notebook); a proposição de ações intencionais de alfabetização, a partir da reorganização de espaços-tempos no cotidiano da escola. Conclui que as discussões teóricas e práticas das questões relacionadas com a linguagem, com os processos cognitivos e com o uso de recursos de TA/CAA alavancam mudanças na concepção dos profissionais das escolas pesquisadas que, ainda, sob uma visão reducionista quanto às formas de comunicação e de interação verbal, “impõem” limites à escolarização dos alunos com deficiência.

A network society communicative model for optimizing the Refugee Status Determination (RSD) procedures

This article recommends a new way to improve Refugee Status Determination (RSD) procedures by proposing a network society communicative model based on active involvement and dialogue among all implementing partners. This model, named after proposals from Castells, Habermas, Apel, Chimni, and Betts, would be mediated by the United Nations High Commissioner for Refugees (UNHCR), whose role would be modeled after that of the International Committee of the Red Cross (ICRC) practice.

Analysis of the return on preventive measures in musculoskeletal disorders through the benefitecost ratio: A case study in a hospital

Work-related musculoskeletal disorders (WMSDs) are among the most costly health problems that society is facing today. Prevention involves investments and it is important for organizations to make a cost ebenefit analysis of ergonomic projects. Return on prevention is a recent concern in the domain of occupational safety and health (OSH). There are many studies concerning the return on the prevention of WMSDs, in terms of the benefits for the organization in which the preventive measures are implemented. However, it is also important to perform an analysis of the impact of each measure on society (externalities). A model to perform a financial and economic costebenefit analysis related to OSH projects was developed and it was applied in the case of the prevention of WMSDs in a Portuguese hospital. An analysis of the accidents and corresponding costs has been made in six of the services of the hospital. Financial and an economic costebenefit analysis have been made and the benefitecost ratio (B/C) has been calculated. While the B/C financial ratio, considering only the benefits to the hospital, is around 2, the economic B/C ratio, taking into account all the external benefits that have been quantified, is higher than 14. Relevance to industry: Both the economic and the financial B/C ratio are important support tools for decision makers in public and private organizations, helping them to define which preventive measures should be implemented, taking into account the costs involved and the resulting quantified benefits, for the organization, for the workers and for the society.

Metodological issues in measuring the detection of emotional disorders by primary care physicians: a review of the literature

A series of studies in the field of Epidemiological Psychiatry have been performed over the last two decades, and these have focused on the ability of primary care physicians to detect emotional disorders in the patients that attend their practices. The scientific methodology utilized in these studies is the subject of this review, which contains a discussion concerning: a) interviewer awareness bias; b) accuracy of the instruments and c) medical and psychological concepts involved in defining minor emotional disorders. Suggestions for change in the methodology are made in each of the sections of the review.

Smoking, consumption of alcohol and sedentary life style in population grouping and their relationships with lipemic disorders

The study, part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetis mellitus in a population of the metropolitan area of the southeastern region of Brazil", had the following objectives: a) the characterization and distribution among typical human socio-economic groupings, of the prevalence of some particular habits which constitute aspects of life-style-the use of tobacco, the use of alcohol and sedentary activity; b) the establishment of the interrelation between the above-mentioned habits and some lipemic disorders. The prevalence of the habits cited behaved in the following manner: the use of tobacco predominated among men, distributed uniformly throughout the social strata; among the women the average percentage of smokers was 18,9%, a significant difference occurring among the highest socio-economic class, where the average was of 40.2%. The sedentary style of life presented high prevalence, among both men and women with exception of the women of the highest socio-economic level and of the skilled working class. The use of alcohol, as one would expect, is a habit basically practised by the men, without any statistically significant differences between classes. For the purpose of establishing associations between these risk fictors and lipemic conditions four situations were chosen, of the following characteristics: 1- total cholesterol > or = 220 mg/dl and triglycerides > or = 150 mg/dl; 2- HDL cholesterol <35 mg/dl for men and <45 mg/dl for women and triglycerides levels > or = 150 mg/dl; 3- HDL cholesterol <35 mg/dl for men and <45 mg/dl for women and triglycerides levels <150 mg/dl; 4- total cholesterol 220 mg/dl with triglycerides levels <150 mg/dl. Six models of multiple (backward) regression were established, with seven independent variables- age, sex, use of tobacco, consumption of alcohol, light physical activity, hypertension and obesity. Significant associations (P<0,05) were revealed with hypercholesterolemia, accompanied by triglyceride levels > or = 150 mg/dl, and the following independent variables: age, use of tobacco and the interactions between obesity and smoking, age and sedentary lifestyle, sex and obesity (R2=22%); the standardized B coefficient showed that the variables with the greatest weight in the forecasting of the variation in the levels of cholesterol were smoking and the interaction between obesity and smoking. The hypercholesterolemia accompanied by triglycerides levels <150 mg/dl showed a positive association between total cholesterol and sex and the interactions obesity/smoking and sex/obesity. As regards HDL cholesterol accompanied by triglyceride/ levels > or = 150 mg/dl was inversely associated with obesity and the interaction smoking/ age and directly with age (R=31%). The standardized B coeffients, indicated that the variables obesity and the interactions smoking/age possessed a weight three times greater than age alone in accounting for the variation in the serum levels of HDL cholesterol. When accompanied by triglycerides <150 mg/dl there was no association between and the independent variables and the set of them presented R equal to 22%. The sum of top, in the population stutied in this project, the component habits of life-style (smoking, alcohol consumption and sedentary activity) which constitute risk factors which determine morbidity from atherosclerotic cardiovascular diseases are be found distributed through all the typical social groupings of this particular form of social organization. On the other hand, the seven independent variables used in the multiple regression models for the explanation of the lipemic conditions considered presented multiple determination coefficients which varied, approximately, between 20% and 30%. Thus it is important that in the genetic epidemiology the study of the morbidities in question be emphasized.

Predicting the revolving door phenomenon among patients with schizophrenic, affective disorders and non-organic psychoses

OBJECTIVE: The aim of the study was to identify the variables that predict the revolving door phenomenon in psychiatric hospital at the moment of a second admission. METHODS: The sample consisted of 3,093 patients who have been followed during 5 to 24 years after their first hospital admission due to schizophrenia, and affective or psychotic disorders. Those who had had four or more admissions during the study period were considered as revolving door patients. Logistic regression analyses were used to assess the impact of gender, age, marital status, urban conditions, diagnosis, mean period of stay on the first admission, interval between the first and second admissions on the patterns of hospitalization. RESULTS: The variables with the highest predictive power for readmission were the interval between first and second admissions, and the length of stay in the first admission. CONCLUSIONS: These data may help public health planners in providing optimal care to a small group of patients with more effective utilization of the available services.
