Avaliação da Morbilidade e Mortalidade no Serviço de Ginecologia da Maternidade Dr. Alfredo da Costa. Jan/Set 1991

Foram avaliados todos os internamentos no Serviço de Ginecologia da MAC de 2 de Janeiro a 19 de Setembro de 1991. O critério de selecção baseou-se no registo de morbilidade intra-operatória e no prolongamento de tempo de internamento. Foram estudados os dados relativos à idade, factores de risco associados, risco anestésico, tipo de intervenção cirúrgica, tempo operatório, tipo de complicações e média de tempo de internamento. Verificou-se uma morbilidade global de 5,6%, tendo-se constatado uma maior incidência de complicações no grupo das histerectomias abdominais (16,8%). Nos casos com morbilidade 72% apresentavam um ou mais factores de risco associados. Ocorreram 5 lesões de órgão (0,73%), 33 complicações pós-operatórias (4,8%) e 7 reintervenções (1%). A média de internamento neste grupo de doentes foi de 11 dias.

Neuropsychiatric Features of a Cohort of Patients with Systemic Lupus Erythematosus

In order to establish if neuropsychiatric systemic lupus erythematosus (NPSLE) can be identified by any characteristic other than those used to diagnose the neuropsychiatric (NP) disease itself, we retrospectively reviewed 98 systemic lupus erythematosus (SLE) patients followed over a mean period of 10 years. NPSLE was identified in 22 patients. Stroke and generalized seizures were the most frequent NP manifestations. The NPSLE and non-NPSLE groups were similar with regard to demographic characteristics, ACR criteria, serum autoantibodies, and frequency of hypertension and hypercholesterolemia. Of note, compared to the non-NPSLE group, NPSLE was associated with a higher frequency of smoking (78 versus 26%), organ damage (73 versus 34%), and cumulative mortality rate (14 versus 7%). The series of patients was further analysed according to the presence of antiphospholipid syndrome (APS). Significantly, the interval between the onset of NP disease and SLE diagnosis was shorter in the APS(-) (0.3 ± 1 years) than in the APS(+) (5 ± 7 years) groups. Recurrence and/or persistence of NP events were only documented in the APS(-) group. Overall cumulative mortality was highest in NPSLE and in APS(+) patients with inadequate anticoagulation control, identifying an aspect that requires improved vigilance and the development of novel therapeutic modalities.

Psicopatologia obsessivo-compulsiva na distonia focal primária : aspectos neuropsiquiátricos de uma doença do movimento

RESUMO: pela contracção involuntária de grupos musculares de extensão variável, originando movimentos involuntários e posturas anómalas, por vezes dolorosas. O tratamento convencional consiste em injecções localizadas de toxina botulínica, podendo, em casos refractários, estar indicado o tratamento por estimulação cerebral profunda. A neurobiologia da distonia focal primária permanece incompletamente compreendida. Os estudos de neuro-imagem estrutural e funcional revelam alterações subtis da anatomia e funcionamento do estriado e das vias cortico-basais, com destaque para o aumento do volume, da actividade metabólica e da neuroplasticidade do putamen e de áreas corticais motoras, pré-motoras e sensitivas. O conjunto destas alterações aponta para uma disrupção da regulação inibitória de programas motores automáticos sustentados pelo estriado e pelas vias ortico-subcorticais. Nos últimos anos tem crescido o interesse pelas manifestações psiquiátricas e cognitivas da distonia (estas últimas muito pouco estudadas). Tem despertado particular interesse a possível associação entre distonia focal primária e perturbação obsessivo-compulsiva (POC), cuja neurobiologia parece notavelmente sobreponível à da distonia primária. Com efeito, os estudos de neuro-imagem estrutural e funcional na POC revelam consistentemente aumento do volume e actividade do estriado e do córtex órbito-frontal, apontando mais uma vez para uma disfunção do controlo inibitório, no estriado, de programas comportamentais e cognitivos automáticos. Objectivos: 1. Explorar a prevalência e intensidade de psicopatologia em geral, e de psicopatologia obsessivo-compulsiva em particular, numa amostra de indivíduos com distonia focal primária; 2. Explorar a ocorrência, natureza e intensidade de alterações do funcionamento cognitivo numa amostra de indivíduos com distonia focal primária; 3. Investigar a associação entre a gravidade da distonia focal, a intensidade da psicopatologia, e a intensidade das alterações cognitivas. Metodologia: Estudo de tipo transversal, caso-controlo, observacional e descritivo, com objectivos puramente exploratórios. Casos: 45 indivíduos com distonia focal primária (15 casos de blefaroespasmo, 15 de cãibra do escrivão, 15 de distonia cervical espasmódica), recrutados através da Associação Portuguesa de Distonia. Critérios de inclusão: idade = 18; distonia focal primária pura (excluindo casos de distonia psicogénica possível ou provável de acordo com os critérios de Fahn e Williams); Metabolismo do cobre e Ressonância Magnética Nuclear sem alterações. Controlos doentes: 46 casos consecutivos recrutados a partir da consulta externa do Hospital Egas Moniz: 15 doentes com espasmo hemifacial, 14 com espondilartropatia cervical, 17 com síndrome do canal cárpico. Controlos saudáveis: 30 voluntários. Critérios de exclusão para todos os grupos: Mini-Mental State Examination patológico, tratamento actual com anti-colinérgicos, antipsicóticos, inibidores selectivos da recaptação da serotonina, antidepressivos tri- ou tetracíclicos. Avaliação: Avaliação neurológica: história e exame médico e neurológico completos. Cotação da gravidade da distonia com a Unified Dystonia Rating Scale. Avaliação psicopatológica: Symptom Check-List-90-Revised; entrevista psiquiátrica de 60 minutos incluindo a Mini-International Neuropsychiatric Interview (MINI), versão 4.4 (validada em Português), complementada com os módulos da MINI Plus versão 5.0.0 para depressão ao longo da vida e dependência/ abuso do álcool e outras substâncias ao longo da vida; Yale-Brown Obsessive-Compulsive Symptom Checklist e a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Avaliação neuropsicológica: Wisconsin Card Sorting Test (WCST; flexibilidade cognitiva); Teste de Stroop (inibição de resposta); Block Assembly Test (capacidade visuo-construtiva); Teste de Retenção Visual de Benton (memória de trabalho visuo-espacial). Análise estatística:os dados foram analisados com a aplicação informática SPSS for Windows, versão 13. Para a comparação de proporções utilizaram-se o teste do Chi-quadrado e o teste de Fisher. Para a comparação de variáveis quantitativas entre dois grupos utilizou-se o teste t de Student ou o teste U de Mann-Whitney (teste de Wilcoxon no caso de amostras emparelhadas). Para comparações de médias entre três grupos recorreu-se à Análise de Variância a um factor (variáveis de intervalo e de rácio), ou ao teste de Kruskal-Wallis (variáveis ordinais). Para o estudo da associação entre variáveis foram utilizados os coeficientes de correlação de Pearson ou de Spearman, a análise de correlações canónicas, a análise de trajectórias e a regressão logística. Adoptou-se um Alpha de 0.05. Resultados: Os doentes com distonia focal primária apresentaram uma pontuação média na Y- -BOCS significativamente superior à dos dois grupos de controlo. Em 24.4% dos doentes com distonia a pontuação na Y-BOCS foi superior a 16. Estes doentes eram predominantemente mulheres, tinham uma maior duração média da doença e referiam predominantemente sintomas obsessivo-compulsivos (SOC) de contaminação e lavagem. Os dois grupos com doença crónica apresentaram pontuações médias superiores às dos indivíduos saudáveis nas escalas de ansiedade, somatização e psicopatologia geral. Os doentes com distonia tratados com toxina botulínica apresentaram pontuações inferiores às dos doentes não tratados nas escalas de ansiedade generalizada, fobia, somatização e depressão, mas não na Y-BOCS. Sessenta por cento dos doentes com distonia apresentavam pelo menos um diagnóstico psiquiátrico actual ou pregresso. O risco de apresentar um diagnóstico psiquiátrico actual era menor nos doentes tratados com toxina botulínica, aumentando com a gravidade da doença. A prevalência de POC foi 8,3% e a de depressão major 37,7%. No WCST e na Prova de Benton, os doentes com distonia focal primária demonstraram um desempenho inferior ao de ambos os grupos de controlo, cometendo sobretudo erros perseverativos. Os doentes com distonia e pontuação na Y-BOCS > 16 cometeram mais erros e respostas perseverativas no WCST do que os restantes doentes com distonia. As análises de correlações e de trajectórias revelaram que nos doentes com distonia a gravidade da distonia foi, juntamente com a idade e a escolaridade, o factor que mais interagiu com o desempenho cognitivo. Discussão: o nosso estudo é o primeiro a descrever, nos mesmos doentes com distonia focal primária, SOC significativos e alterações cognitivas. Os nossos resultados confirmam a hipótese de uma associação clínica específica entre distonia focal primária e psicopatologia obsessivo-compulsiva. Confirmam igualmente que a distonia focal primária está associada a um maior risco de desenvolver morbilidade psiquiátrica ansiosa e depressiva. O tratamento com toxina botulínica reduz este risco, mas não influencia os SOC. Entre os doentes com distonia, os que têm SOC significativos poderão diconstituir um grupo particular com maior duração da doença (mas não uma maior gravidade), predomínio do sexo feminino e predomínio de SOC de contaminação e limpeza. Em termos cognitivos, os indivíduos com distonia focal primária apresentam défices significativos de flexibilidade cognitiva (particularmente acentuados nos doentes com SOC significativos) e de memória de trabalho visuo-espacial. Estes últimos devem-se essencialmente a um défice executivo e não a uma incapacidade visuo-construtiva ou visuo-perceptiva. A disfunção cognitiva não é explicável pela psicopatologia depressiva nem pela incapacidade motora, já que os controlos com doença periférica crónica tiveram um desempenho superior ao dos doentes com distonia. No seu conjunto os nossos resultados sugerem que os SOC que ocorrem na distonia focal primária constituem uma das manifestações clínicas da neurobiologia desta doença do movimento. O predomínio de sintomas relacionados com higiene e o perfil disexecutivo de alterações cognitivas–perseveração e dificuldades executivas de memória de trabalho visuo-espacial – apontam para a via cortico-basal dorso-lateral e para as áreas corticais que lhe estão associadas como estando implicadas na tripla associação entre sintomas motores, obsessivo-compulsivos e cognitivos. Conclusões: A distonia focal primária é um síndrome neuropsiquiátrico complexo com importantes manifestações não motoras, nomeadamente compromisso cognitivo do tipo disexecutivo e sintomas obsessivo-compulsivos. Clinicamente estas manifestações representam necessidades de tratamento que vão muito para além da simples incapacidade motora, devendo ser activamente exploradas e tratadas.-------------- ABSTRACT: Introduction: primary focal dystonia is an idiopathic movement disorder that manifests as involuntary, sustained contraction of muscular groups, leading to abnormal and often painful postures of the affected body part. Treatment is symptomatic, usually with local intramuscular injections of botulinum toxin. The neurobiology of primary focal dystonia remains unclear. Structural and functional neuroimaging studies have revealed subtle changes in striatal and cortical-basal pathway anatomy and function. The most consistent findings involve increased volume and metabolic activity of the putamen and of motor, pre-motor and somato-sensitive cortical areas. As a whole, these changes have been interpreted as reflecting a failure of striatal inhibitory control over automatic motor programs sustained by cortical-basal pathways. The last years have witnessed an increasing interest for the possible non-motor – mainly psychiatric and cognitive – manifestations of primary focal dystonia. The possible association of primary focal dystonia with obsessive-compulsive disorder (OCD) has raised particular interest. The neurobiology of the two disorders has indeed remarkable similarities: structural and functional neuroimaging studies in OCD have revealed increased volume and metabolic activity of the striatum and orbital-frontal cortex, again pointing to a disruption of inhibitory control of automatic cognitive and behavioural programs by the striatum. Objectives: 1. To explore the prevalence and severity of psychopathology – with a special emphasis on obsessive-compulsive symptoms (OCS) – in a sample of patients with primary focal dystonia;2. To explore the nature and severity of possible cognitive dysfunction in a sample of patients with primary focal dystonia; 3. To explore the possible association between dystonia severity, psychiatric symptom severity, and cognitive performance, in a sample of patients with primary focal dystonia. Methods: cross-sectional, case-control, descriptive study. Cases: forty-five consecutive, primary pure focal dystonia patients recruited from the Portuguese Dystonia Association case register (fifteen patients with blepharospasm, 15 with cervical dystonia and 15 with writer’s cramp). Inclusion criteria were: age = 18; primary pure focal, late-onset dystonia (excluding possible or probable psychogenic dystonia according to the Fahn & Williams criteria); normal copper metabolism and Magnetic Resonance Imaging. Diseased controls: forty-six consecutive subjects from our hospital case register (15 patients with hemi-facial spasm; 14 with cervical spondilarthropathy and cervical spinal root compression; 17 with carpal tunnel syndrome). Healthy controls were 30 volunteers.Exclusion criteria for all groups: Mini-Mental State Examination score below the validated cut-off for the Portuguese population (<23 for education between 1 and 11 years; <28 for education >11 years); use of anti-cholinergics, neuroleptics, selective serotonin reuptake inhibitors, triciclic or tetraciclic antidepressants. Assessment: neurological assessment: complete medical and neurological history and physical examination; dystonia severity scoring with the Unified Dystonia Rating Scale. Psychiatric assessment:Symptom Check-List-90-Revised; 60 minute-long psychiatric interview, including Mini-International Neuropsychiatric Interview (MINI), version 4.4 (validated Portuguese version), extended with the sections for life-time major depressive disorder and life-time alcohol and substance abuse disorder from MINI-Plus version 5.0.0; Yale-Brown Obsessive-Compulsive Symptom Checklist and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Cognitive assessment: Wisconsin Card Sorting Test (WCST; cognitive set-shifting ability); Stroop Test (response inhibition); Block Assembly Test(visual-constructive ability); Benton’s Visual Retention Test (visual-spatial working memory). Statistic analysis: Data were analyzed with SPSS for Windows version 13. Proportions were compared using Chi-Square test, or Fisher’s exact test when appropriate. Student’s t-test or Mann-Whitney’s U test (or Wilcoxon’s teste in the case of matched samples) were used for two-group comparisons. P-values were corrected for multiple comparisons. One-way ANOVA with Bonferroni post-hoc analysis (interval data), or the Kruskal-Wallis Test (ordinal data), were used for three-group comparisons. Associations were analysed with Pearson’s or Spearman’s correlation coefficients, canonical correlations, path analysis and logistic regression analysis. Alpha was set at 0.05. Results: Dystonia patients had higher Yale-Brown Obsessive-Compulsive Symptom scores than both control groups. 24.4% of primary dystonia patients had a Y-BOCS score > 16. These patients were predominantly women; they had longer disease duration, and showed a predominance of hygiene-related OCS. The two groups with chronic disease had higher anxiety, somatization and global psychopathology scores than healthy subjects. Primary dystonia patients undergoing treatment with botulinum toxin had lower anxiety, phobia, somatization and depression scores than their untreated counterparts, but similar Y-BOCS scores. Sixty percent of primary dystonia patients had at least one lifetime psychiatric diagnosis. The odds of having a currently active psychiatric diagnosis were lower in botulinum toxin treated patients, and increased with dystonia severity. The prevalence of OCD was 6.7%, and the lifetime prevalence of major depression was 37.7%. Primary dystonia patients had a lower performance than the two control groups in both the WCST and Benton’s Visual Retention Test, mainly due to an excess of perseveration errors. Primary dystonia patients with Y-BOCS score > 16 had much higher perseveration error and perseveration response scores than dystonia patients with Y-BOCS = 16. Correlation and path analysis showed that, in the primary dystonia group, dystonia severity, along with age and education, was the main factor influencing cognitive performance. Discussion: our study is the first description ever of concomitant significant OCS and cognitive impairment in primary dystonia patients. Our results confirm that primary dystonia is specifically associated with obsessive-compulsive psychopathology. They also confirm that primary focal dystonia patients are at a higher risk of developing anxious and depressive psychiatric morbidity. Treatment with botulinum toxin decreases this risk, but does not influence OCS. Primary focal dystonia patients with significant OCS may constitute a particular subgroup. They are predominantly women, with higher disease duration (but not severity) and a predominance of hygiene related OCS.In terms of cognitive performance, primary focal dystonia patients have significant deficits involving set-shifting ability and visual-spatial working memory. The latter result from an essentially executive deficit, rather than from a primary visual-constructive apraxia or perceptual deficit. Furthermore, cognitive flexibility difficulties were more prominent in the subset of primary dystonia patients with significant OCS. The cognitive dysfunction found in dystonia patients is not attributable to depressive psychopathology or motor disability, as their performance was significantly lower than that of similarly impaired diseased controls. Our results suggest that OCS in primary focal dystonia are a direct, primary manifestation of the motor disorder’s neurobiology. The predominance of hygiene-related symptoms and the disexecutive pattern of cognitive impairment – set-shifting and visual-spatial working memory deficits – suggest that the dorsal-lateral cortical-basal pathway may play a decisive role in the triple association of motor dysfunction, OCS and cognitive impairment. Conclusions: primary focal dystonia is a complex neuropsychiatric syndrome with significant non- -motor manifestations, namely cognitive executive deficits and obsessive-compulsive symptoms.Clinically, our results show that PFD patients may have needs for care that extend far beyond a merely motor disability and must be actively searched for and treated.

Web-assisted tobacco intervention in Portuguese : intentions to make behavioural changes and behavioural changes

ABSTRACT - The problem of how to support “intentions to make behavioural changes” (IBC) and “behaviour changes” (BC) in smoking cessation when there is a scarcity of resources is a pressing issue in public health terms. The present research focuses on the use of information and communications technologies and their role in smoking cessation. It is developed in Portugal after the ratification of WHO Framework Convention on Tobacco Control (on 8 November 2005). The prevalence of smokers over fifteen years of age within the population stood at 20.9% (30.9% for men and 11.8% for women). While the strategy of helping people to quit smoking has been emphasised at National Health Service (NHS) level, the uptake of cessation assistance has exceeded the capacity of the service. This induced the search of new theoretical and practical venues to offer alternative options to people willing to stop smoking. Among these, the National Health Plan (NHP) of Portugal (2004-2010), identifies the use of information technologies in smoking cessation. eHealth and the importance of health literacy as a means of empowering people to make behavioural changes is recurrently considered an option worth investigating. The overall objective of this research is to understand, in the Portuguese context, the use of the Internet to help people to stop smoking. Research questions consider factors that may contribute to “intentions to make behavioural changes” (IBC) and “behavioural changes” (BC) while using a Web-Assisted Tobacco Intervention Probe (WATIP). Also consideration is given to the trade-off on the use of the Web as a tool for smoking cessation: can it reach a vast number of people for a small cost (efficiency) demonstrating to work in the domain of smoking cessation (efficacy)”? In addition to the introduction, there is a second chapter in which the use of tobacco is discussed as a public health menace. The health gains achieved by stopping smoking and the means of quitting are also examined, as is the use of the Internet in smoking cessation. Then, several research issues are introduced. These include background theory and the theoretical framework for the Sense of Coherence. The research model is also discussed. A presentation of the methods, materials and of the Web-Assisted Tobacco Intervention Probe (WATIP) follows. In chapter four the results of the use of the Web-Assisted Tobacco Intervention Probe (WATIP) are presented. This study is divided into two sections. The first describes results related to quality control in relation to the Web-Assisted Tobacco Intervention Probe (WATIP) and gives an overview of its users. Of these, 3,150 answered initial eligibility questions. In the end, 1,463 met all eligibility requirements, completed intake, decided on a day to quit smoking (Dday) and declared their “intentions to make behavioural changes” (IBC) while a second targeted group of 650 did not decide on a Dday. With two quit attempts made before joining the platform, most of the participants had experienced past failures while wanting to stop. The smoking rate averaged 21 cigarettes per day. With a mean age of 35, of the participants 55% were males. Among several other considerations, gender and the Sense of Coherence (SOC) influenced the success of participants in their IBC and endeavour to set quit dates. The results of comparing males and females showed that, for current smokers, establishing a Dday was related to gender differences, not favouring males (OR=0.76, p<0.005). Belonging to higher Socio-economic strata (SES) was associated with the intention to consider IBC (when compared to lower SES condition) (OR=1.57, p<0.001) and higher number of school years (OR=0.70, p<0.005) favoured the decision to smoking cessation. Those who demonstrated higher confidence in their likelihood of success in stopping in the shortest time had a higher rate of setting a Dday (OR=0.51, p<0.001). There were differences between groups in IBC reflecting the high and low levels of the SOC score (OR=1.43, p=0.006), as those who considered setting a Dday had higher levels of SOC. After adjusting for all variables, stages of readiness to change and SOC were kept in the model. This is the first Arm of this research where the focus is a discussion of the system’s implications for the participants’ “intentions to make behavioural changes” (IBC). Moreover, a second section of this study (second Arm) offers input collected from 77 in-depth interviews with the Web-Assisted Tobacco Intervention Probe (WATIP) users. Here, “Behaviour Change” (BC) and the usability of the platform are explored a year after IBC was declared. A percentage of 32.9% of self-reported, 12-month quitters in continuous abstinence from smoking from Dday to the 12-month follow- up point of the use of the Web-Assisted Tobacco Intervention Probe (WATIP) has been assessed. Comparing the Sense of Coherence (SOC) scores of participants by their respective means, according to the two groups, there was a significant difference in these scores of non smokers (BC) (M=144,66, SD=22,52) and Sense of Coherence (SOC) of smokers (noBC) (M=131,51, SD=21,43) p=0.014. This WATIP strategy and its contents benefit from the strengthening of the smoker’s sense of coherence (SOC), so that the person’s progress towards a life without tobacco may be experienced as comprehensible, manageable and meaningful. In this sample the sense of coherence (SOC) effect is moderate although it is associated with the day to quit smoking (Dday). Some of the limitations of this research have to do with self-selection bias, sample size (power) and self-reporting (no biochemical validation). The enrolment of participants was therefore not representative of the smoking population. It is not possible to verify the Web-Assisted Tobacco Intervention Probe (WATIP) evaluation of external validity; consequently, the results obtained cannot be applied generalized. No participation bias is provided. Another limitation of this study is the associated limitations of interviews. Interviewees’ perception that fabricating answers could benefit them more than telling the simple truth in response to questions is a risk that is not evaluated (with no external validation like measuring participants’ carbon monoxide levels). What emerges in this analysis is the relevance of the process that leads to the establishment of the quit day (Dday) to stop using tobacco. In addition, technological issues, when tailoring is the focus, are key elements for scrutiny. The high number of dropouts of users of the web platform mandates future research that should concentrate on the matters of the user-centred design of portals. The focus on gains in health through patient-centred care needs more research, so that technology usability be considered within the context of best practices in smoking cessation.

Programas de cuidados integrados para pessoas com esquizofrenia ou perturbação esquizoafetiva : estudo sobre a exequibilidade, implementação e resultados de um programa de cuidados integrados para pessoas com esquizofrenia ou perturbação esquizoafectiva em Portugal

RESUMO: De acordo com o estado da arte, existem intervenções psicofarmacológicas, psicológicas e psicossocias, com evidência científica dos seus resultados, no tratamento de pessoas com esquizofrenia e perturbação esquizoafectiva. No entanto, muitos destes doentes, não procuram ajuda dos serviços de saúde mental, não recebem os referidos cuidados ou não são detectados nem seguidos por estes. Esta realidade levou ao desenvolvimento de programas integrados, intervenções e estudos mais específicos, nomeadamente para tentar ultrapassar os obstáculos na acessibilidade aos cuidados de saúde e na continuidade de seguimento destes doentes. No conjunto das dificuldades apuradas, as questões da exequibilidade (feasibility) e da implementação, têm tido particular relevo na literatura científica recente, bem como a melhor forma de vencer as respectivas barreiras e adaptar essas intervenções às varias realidades, culturas e recursos. Objectivos: Objectivos gerais:1) Avaliar a exequibilidade e a implementação inicial de um programa de cuidados integrados, para pessoas com esquizofrenia ou perturbação esquizoafectiva, no contexto clínico das equipas de saúde mental comunitárias de um departamento de psiquiatria do Serviço Nacional de Saúde, em Portugal, com os recursos materiais e humanos existentes; 2) Avaliar o impacto deste programa, nestes doentes e na respectiva prestação de cuidados de saúde mental. Metodologia. Elaborámos um programa de cuidados integrados (Programa Integrar) com base no modelo clínico de case management, com seguimento mantido e integrado. Cada doente passou a ter um terapeuta de referência, um plano individual de cuidados e manteve o seguimento com o seu psiquiatra assistente. Foram seleccionadas intervenções, nomeadamente, psicoeducativas, familiares, estratégias para lidar com os sintomas e a doença, prevenção de recaídas e intervenções para melhorar o funcionamento social e ocupacional. A estas intervenções foi sempre associado o tratamento psicofarmacológico. O estudo delineado incluiu dois componentes: avaliação da exequibilidade e implementação inicial do programa de cuidados integrados (componente A) e avaliação do impacto deste programa (componente B), através de um estudo de intervenção, prospectivo, naturalista, não aleatorizado e não ontrolado. A amostra do estudo resultou das sucessivas referenciações, para o Programa Integrar, de pessoas com os diagnósticos de esquizofrenia ou perturbação esquizoafectiva, seguidas nas cinco equipas de saúde mental comunitárias do Departamento de Psiquiatria do Centro Hospitalar de Lisboa Ocidental, com uma área assistencial correspondente a uma população de, aproximadamente, 400 000 pessoas. Definimos etapas, estratégias, parâmetros e indicadores para o estudo da exequibilidade do programa. Efectuámos a monitorização e a avaliação de tarefas, procedimentos e intervenções recomendadas aos terapeutas de referência. Realizámos duas avaliações, uma no início do programa e outra após um ano de intervenção. Foram avaliadas as seguintes dimensões (com indicação do acrónimo do instrumento de avaliação utilizado entre parêntesis): psicopatologia (BPRS), depressão (MADRS), necessidades (CAN), incapacidade (DAS), actividade social e ocupacional (SOFAS), atitude em relação à medicação (DAI), insight (SAI), qualidade de vida (WHOQOL-S) e satisfação (POCS). Resultados: Dos 146 doentes que foram incluídos no estudo, 97 (66%) eram do sexo masculino e 49 (34%) do sexo feminino, com uma idade média de 36 anos. Destes oentes,116 (79,4%)tinham o diagnóstico (ICD10) de esquizofrenia e 30 (20,6%) de perturbação esquizoafectiva. Os restantes dados sociodemográficos eram típicos de populações afins em serviços de saúde mental nacionais. Do total de doentes (146) que iniciaram o estudo, 26 (18%) abandonaram o seguimento neste programa. Para o componente A da investigação (estudo de exequibilidade) salientamos: exerceram funções a totalidade (15) dos terapeutas de referência que receberam formação, 76 % efectuaram o número mínimo recomendado de sessões / ano por doente (≥18), 44,9 fizeram o número mínimo de sessões familiares pretendido (≥ 3). Nas intervenções mais específicas foram atingidos os objectivos em mais de 75% dos doentes, à excepção das intervenções domiciliárias (19,4%), prevenção do abuso de substâncias (45,4%) e do risco de suicídio (34,3%). O plano individual de cuidados foi realizado em 98 % dos doentes e em 38,9 % dos casos ocorreu a participação da família. Neste plano, a média de objectivos definidos foi de 5 e a média de objectivos atingidos correspondeu a 3 (p= 0,001). Na primeira avaliação, estavam a frequentar estruturas de reabilitação psicossocial 42 doentes (28,8%) e,12 meses após, esse número passou para 80 (74,1%).Também aumentou o número de doentes com actividade profissional a tempo completo, de 8 (7,4%) para 18 (16,7%). No componente B do estudo (avaliação do impacto do programa), em termos de psicopatologia, e para as pontuações médias globais do BPRS, ocorreu uma diminuição entre a primeira e a segunda avaliação (p=0,001), tal como nas subescalas: sintomas positivos (p=0,003), sintomas negativos (p=0,002), sintomas de mania (p=0,002) e sintomas de depressão/ansiedade (p=0,001). Na avaliação da depressão (p= 0,001) e da incapacidade (p=0,003), as diferenças foram significativas e favoráveis. O mesmo não sucedeu na atitude em relação à medicação (p=0,690) nem na escala de avaliação do insight (p=0,079). Em relação ao funcionamento social e ocupacional, qualidade de vida e satisfação dos doentes, ocorreu uma melhoria significativa da primeira para a segunda avaliação As necessidades sem resposta mais frequentes, na primeira avaliação, corresponderam aos itens: actividades diárias, contactos sociais, relações íntimas, relacionamento sexual, benefícios sociais, sintomas psicóticos, sofrimento psicológico, informação sobre a doença / tratamento e gestão/problemas de dinheiro. Para todos estes últimos nove itens, verificou-se uma diferença estatisticamente significativa, entre a primeira e a segunda avaliação, com diminuição destas necessidades, excepto nas relações íntimas, relacionamento sexual e nos problemas de dinheiro. Na distribuição dos três estados de necessidades, para todos os itens, diminuíram as necessidades sem resposta e as necessidades com resposta parcial e aumentaram as situações em que deixaram de se verificar necessidades relevantes. Dos resultados obtidos para outros indicadores clínicos e de utilização dos cuidados, será importante referir que na comparação do ano anterior com o ano em que decorreu o programa, o número de doentes da amostra internados diminuiu 64,1%, bem como a média do número de internamentos (p=0,001). Em relação à duração dos internamentos, no ano anterior ao programa, os 39 doentes internados, tiveram um total de dias de internamento de 1522, sendo que, no ano do programa, para os 14 doentes internados, o total foi de 523 dias. Em termos absolutos, ocorreu uma redução de 999 dias (menos 65,6% dias). Também se verificou uma diminuição de 45,6 % de recaídas (p=0,001).Discussão e conclusões A exequibilidade do programa de cuidados integrados permitiu a aplicação do modelo clínico de case management, com seguimento mantido e integrado, através do qual cada doente passou a ter um terapeuta de referência assim como, em 98% casos, um plano individual de cuidados. As famílias continuaram a ser o principal suporte para os doentes, mas surgiram dificuldades quando se pretendeu uma participação mais activa destas no tratamento.A diminuição do número e da duração dos internamentos constituíram importantes resultados com implicações não só em termos clínicos mas também económicos. Os valores obtidos, para as diferentes variáveis, também sugerem o impacto favorável do Programa Integrar a nível da psicopatologia, das necessidades, da incapacidade, do funcionamento social e ocupacional, da qualidade de vida e da satisfação dos doentes. O mesmo não sucedeu para o insight e para a mudança de atitudes dos doentes em relação à medicação, resultados que devem ser igualmente considerados em futuros reajustamentos deste programa ou no desenvolvimento de novos programas. Como principais conclusões podemos referir que: 1) Foi possível a exequibilidade de um programa de cuidados integrados inovador e a implementação inicial desse programa, para doentes com esquizofrenia ou perturbação esquizoafectiva, com os recursos humanos e materiais existentes, no contexto clínico das equipas de saúde mental comunitárias, de um departamento de psiquiatria e saúde mental, em Portugal; 2) Na avaliação do impacto do programa, os resultados obtidos indiciam potencialidades de aplicação, deste programa de cuidados integrados, com vista à melhoria clínica e psicossocial destes doentes. Devem ser realizados estudos de replicação, ou complementares à presente investigação, no entanto, os dados obtidos são encorajadores para o desenvolvimento de programas similares, a nível nacional e internacional, que possam beneficiar um grupo mais alargado de doentes.------------ABSTRACT: Although there are psychological and psychosocial interventions well supported by scientific evidence, which show benefit when combined with psychopharmacological treatments, we know that a significant number of people with schizophrenia or schizoaffective disorders, do not seek help from mental health services, do not receive the care mentioned and are not detected or followed-up by them. This reality led to the development of integrated programs, interventions and more specific studies, to try to overcome the obstacles in the accessibility to the health services and on the follow-up of these patients. Amongst the barriers identified, feasibility and implementation of those programs have been of special relevance in recent scientific literature, as well as the best way to overcome such difficulties and adapt the interventions to the various realities, cultures and resources. Objectives: General objectives were defined: 1) Assessment of the feasibility and initial implementation of an integrated care program, for people with schizophrenia or schizoaffective disorder, in the clinical setting of community mental health teams, in a psychiatric department from the national health service in Portugal; 2) Impact evaluation of the integrated care program, for these patients and their mental health care delivery. Methods: We drew up an integrated care program (Program Integrar) based on the clinical case management model, with continuous and integrated follow-up. Each patient got one case manager, an individual care plan and kept the same psychiatrist. Were selected the appropriated interventions, namely: psycho-educative, family-based interventions, strategies for dealing with the symptoms and the disorder, relapse prevention and interventions to improve social and occupational functioning. These interventions were always associated with psychopharmacological treatment. The investigation was outline with two parts: assessment of the feasibility and initial implementation of the Program Integrar (part A of the study) and impact evaluation of the program (part B of the study). We designed a naturalistic, prospective, intervention study, non-randomized and without control group. Our chosen sample was made with successive referrals of patients with the diagnosis of schizophrenia or schizoaffective disorder, followedup in one of the five community mental health teams of the Psychiatric Department of Centro Hospitalar Lisboa Ocidental, with a catchment area for a population of about 400 000 people. Different stages, strategies, criteria and indicators for studying the feasibility of the program and its implementation were set and the tasks, procedures and recommended interventions of the case managers were monitored and evaluated. We did two assessments with an interval of one year and we evaluated the following dimensions (the acronym of the assessment instrument used in brackets): psychopathology (BPRS), depression (MADRS), needs (CAN), disability (DAS), social and occupational functioning (SOFAS), attitude toward medication (DAI), insight (SAI), quality of life (WHOQOL-S) and satisfaction (POCS). Results: Of the 146 patients who started the study, 97 (66%) were male and 49 (34%) females with a mean age of 36 years. Of these, 116 (79,4%) were diagnosed (ICD10) with schizophrenia and 30 (20,6%) with schizoaffective disorder. The other socio-demographic data were typical of populations within Portuguese mental health services. Of all patients (146), who started the program, 26 (18%) of patients left the program (program dropout rate). Of the regarding part A of the study, which focused on feasibility, the following is of note: all professionals who had been trained for this purpose (15) acted as case manager, 76% did the recommended minimum number of sessions / year per patient (≥18) and 44,9% did the minimum number of family sessions desired (≥ 3). For the more specific interventions the parameters set out were met for more than 75% of patients, with the exception of domiciliar interventions (19.4%), prevention of substance abuse (45.4%) and suicide risk prevention(34.3%). The individual care plan was done for 98% of patients and in 38,9% of cases this involved family participation. For this plan the mean objectives defined were 5 and in average was achieved 3 (p=0,001). On the first assessment, 42 patients (28.8%) were attending psychosocial rehabilitation structures and 12 months later that number rose up to 80 (74,1%). Regarding their employment status, in the first assessment 8 (7,4%) were in full time employment and in the second evaluation the number rise to 18 (16,7%). For part B of the study (impact program evaluation), in terms of psychopathology, global mean scores for the BPRS, decreased (p=0,001), as did the four sub scales: positive symptoms (p=0,003); negative symptoms (p=0,002); manic symptoms (p=0,002) and symptoms of depression/anxiety (p=0,001). Both in the evaluation of depression (p=0,001), as in the assessment of disability (p=0,003), the differences were significant. However, this was not the case with attitudes towards medication (p=0,690) and with insight evaluation (p=0,079). In relation to social and occupational functioning, quality of life and patient satisfaction there was a statistically significant improvement from the first to the second assessment. The most commonly unmet needs in the first assessment were daily activities, social contacts, intimate relationships, sexual relations, social benefits, psychotic symptoms,psychological distress, information about the disorder / treatment and money problems money management. Of these, in the second assessment, all of those nine unmet needs showed significant improvement, excepted intimate relationships, sexual relations and Money problems / money management. In the distribution of the three states of needs for all items, it happened a decreased in unmet needs and partially met needs and increased in the situations where relevant needs were no longer found. For other clinical indicators it is important to note, when we compared the year prior to this program and the year after, there were fewer hospitalizations (reduction of 64,1% of admissions) and in the mean number of admissions (p=0,001). Regarding the length of hospitalization in the year prior to the program, the 39 patients admitted had a total of 1522 hospital days, and in the year of the program for the 14 hospitalized patients, the total was 523 days. In absolute terms, there was a reduction of 999 days (65,6%). There was also a 45,6% reduction of relapses (p = 0,001). Discussion and Conclusions: The feasibility of the integrated care program allowed the application of the clinical case management model, with continuous follow-up. Each patient got a case manager and in 98% of the cases they also got an individual plan of care. Families continued to be the main support for patients but, difficulties occurred when it was claimed a more active participation. The decrease in the number and duration of admissions were important findings with implications not only in clinical terms but also in economic field. The achieved results for the different variables can also indicate the favorable impact of this program, at the level of psychopathology, needs, disability, social and occupationa functioning, quality of life and patient satisfaction. The same did not happen for the evaluation of insight and in the changes of attitudes towards medication. These data should also be considered for future readjustments of this program and for the developing of new programs.Finally, the two-overview conclusions are: 1) It was possible the feasibility of an integrated care program and initial implementation of this innovative program, for patients with schizophrenia or schizoaffective disorder, with the human and material resources available in the clinical context of the community mental health teams, in a psychiatry and mental health department of the national health service in Portugal; 2) In assessing the impact of the program, the results suggest potential application of this integrated care program, to improve clinical state and psychosocial variables for these patients. There should be done studies to replicate these results, however the results obtained are promising for the development of similar programs at nationally and internationally level, that could benefit a wider group of patients.

Constraint reasoning with local search for continuous optimization

Optimization is a very important field for getting the best possible value for the optimization function. Continuous optimization is optimization over real intervals. There are many global and local search techniques. Global search techniques try to get the global optima of the optimization problem. However, local search techniques are used more since they try to find a local minimal solution within an area of the search space. In Continuous Constraint Satisfaction Problems (CCSP)s, constraints are viewed as relations between variables, and the computations are supported by interval analysis. The continuous constraint programming framework provides branch-and-prune algorithms for covering sets of solutions for the constraints with sets of interval boxes which are the Cartesian product of intervals. These algorithms begin with an initial crude cover of the feasible space (the Cartesian product of the initial variable domains) which is recursively refined by interleaving pruning and branching steps until a stopping criterion is satisfied. In this work, we try to find a convenient way to use the advantages in CCSP branchand- prune with local search of global optimization applied locally over each pruned branch of the CCSP. We apply local search techniques of continuous optimization over the pruned boxes outputted by the CCSP techniques. We mainly use steepest descent technique with different characteristics such as penalty calculation and step length. We implement two main different local search algorithms. We use “Procure”, which is a constraint reasoning and global optimization framework, to implement our techniques, then we produce and introduce our results over a set of benchmarks.

Occurrence of severe dengue in Rio de Janeiro: an ecological study

Introduction This study aimed to analyze the relationship between the incidence of severe dengue during the 2008 epidemic in Rio de Janeiro, Brazil, and socioeconomic indicators, as well as indicators of health service availability and previous circulation of the dengue virus serotype-3 (DENV-3). Methods In this ecological study, the units of analysis were the districts of Rio de Janeiro. The data were incorporated into generalized linear models, and the incidence of severe dengue in each district was the outcome variable. Results The districts with more cases of dengue fever in the 2001 epidemic and a higher percentage of residents who declared their skin color or race as black had higher incidence rates of severe dengue in the 2008 epidemic [incidence rate ratio (IRR)= 1.21; 95% confidence interval (95%CI)= 1.05-1.40 and IRR= 1.34; 95%CI= 1.16-1.54, respectively]. In contrast, the districts with Family Health Strategy (FHS) clinics were more likely to have lower incidence rates of severe dengue in the 2008 epidemic (IRR= 0.81; 95%CI= 0.70-0.93). Conclusions At the ecological level, our findings suggest the persistence of health inequalities in this region of Brazil that are possibly due to greater social vulnerability among the self-declared black population. Additionally, the protective effect of FHS clinics may be due to the ease of access to other levels of care in the health system or to a reduced vulnerability to dengue transmission that is afforded by local practices to promote health.

EDP inovcity pilot study proposal: A set-top box interface

In this work I propose an additional test to be implemented in EDP’s residential electricity use feedback trials, under InovCity’s project scope. The proposed product to be tested consists of an interface between the smart meter and the television, through a set-top box. I provide a theoretical framework of the importance of feedback, an analysis of results from past studies involving smart metering, and a detailed description of my proposal. The results of a self-developed questionnaire related to the proposal and segmentation issues are also analyzed. Finally, general conclusions are drawn and potential future improvements and challenges are presented.

How aspiring filmmakers cope with unexpected events on set

Making the transition between plans and unexpected occurrences is something organizations are used to doing every day. However, not much is known about how actors cope with unanticipated events and how they accommodate them within predefined schedules. In this study, we draw on an inductive analysis of aspiring filmmakers’ film sets to elaborate on how they plan their shooting activities every day, only to adjust them when unforeseen complications arise. We discover that film crews anchor their expectations for the day based on a planned shooting schedule, yet they incorporate a built-in assumption that it will inevitably be disrupted. We argue that they resort to triage processes and “troubleshooting protocols” that help decipher incoming problems. Familiar problems are solved by making use of experience obtained from past situations, whereas unprecedented problems are solved through a tacit protocol used as a tool to quickly devise an appropriate game plan. This study contributes to the literature on sense-making and provides valuable information about the unexplored world of filmmaking.

Regret associated with past and future messes under a maximizing mind-set

Promotions can make you happy if you get the “best” deal or miserable if you miss it. Previous research on this topic has shown that people favor products associated with a past miss to products associated with a future miss, and people in a maximizing mind-set, i.e. people who search for the best in different domains, feel more regret in a consumption domain. This research confirms that consumers prefer purchasing a product associated with a past miss (Experiments 1 and 2) and that regret levels are higher when participants come across the future miss, under the maximizing mind-set (Experiment 2). These studies add to the notion that information on regret might prompt people to make decisions towards a more optimistic outcome.
