Uma perspectiva foucaudiana na auditoria à avaliação de desempenho na administração pública

Motivation: Auditing is not merely a collection of technical tasks but also a programmatic idea circulating in organizational environment, an idea which promises a certain style of control and organizational transparency (Power, 1998, p. 122) Performance appraisal within public organization aims to promote this organizational transparency and promote learning and improvement process both for employees and for the organization. However, we suggest that behind its clear intentions, there are some other goals tied to performance appraisal that could be seen as components of a discipline and surveillance systems to make the employee “knowable, calculable and administrative object” (Miller and Rose, 1990, p. 5). Objective: In Portuguese public organizations, performance appraisal follows the SIADAP (Performance Appraisal Systems for Public Administration). The objective of this study is to capture whatever employees of public organizations (appraisers and appraisee) perceived the performance appraisal system (SIADAP) as an appraisal model that promotes equity, learning and improvement or just as an instrument of control to which they feel dominated and watched over. Method: We developed an in-depth qualitative case study using semi-structured interviews with appraisers and their subordinates in the administrative department of a university institute of Medicine. The discourse of the participants was theoretically analyzed based on Foucauldian framework. Prior to qualitative data collection, we collected quantitative data, with a questionnaire, to measure the (un)satisfaction of employees with the all appraisal system. Findings: Although some key points of Foucault perspective were identified, its framework revealed some limitations to capture the all complexity of performance appraisal. Qualitative data revealed a significant tendency in discourses of appraisers and their subordinates considering SIADAP as an instrument that’s aims to introduced political rationalities and limits to the employer’s promotions within their careers. Contribution: This study brings a critical perspectives and new insights about performance appraisals in Portuguese’s public administrations. It is original contribution to management of human recourses in public administration and primary to audit of performance appraisal systems.

O Valor Prognóstico da Resposta Neutrofílica na Era da Reperfusão Mecânica do Enfarte Agudo do Miocárdico

BACKGROUND: In ST-segment elevation myocardial infarction (STEMI) patients treated with primary angioplasty, neutrophil response and its prognostic significance are not entirely understood. METHODS: We retrospectively studied 305 consecutive and non-selected STEMI patients. They were divided into three groups according to the maximum neutrophil percentage in the first 48 hours. We compared baseline demographic characteristics, coronary disease risk factors, cardiac history, clinical presentation, therapeutics administered and clinical evolution. We then assessed survival in the three groups and determined predictors of 30-day mortality. Group 1 (G1) had a mean age of 57 +/- 14 years and showed mean neutrophilia of 73.3%, Group 2 (G2) 61 +/- 13 years and 79.9%, and Group 3 (G3) 66 +/- 13 years and 84.2%. We compared outcomes and 30-day mortality between the groups. RESULTS: Mean age rose with increased neutrophil response. There were no statistically significant baseline differences between the groups except for more smokers in Groups 1 and 2, and more patients presenting with Killip class > or = 2 and fewer with uncomplicated evolution in Group 3. During 30-day follow-up there were 19 deaths (G1=1, G2=3 and G3=15). In univariate analysis mortality predictors were age > or = 75 years, anterior STEMI, maximum creatinine kinase > or = 2500 UI/L, culprit lesion in proximal anterior descending artery, incomplete revascularization, Killip > or = 2 at presentation, and being in G3. After multivariate regression analysis independent predictors were age > or = 75 years, incomplete revascularization and being in G3. CONCLUSION: In myocardial infarction patients undergoing mechanical revascularization, an intense neutrophil response (routinely, easily and inexpensively assessed) is related to worse short-term prognosis.

Candida bloodstream infection: data from a teaching hospital in Mato Grosso do Sul, Brazil

The incidence of Candida bloodstream infection has increased over the past years. In the Center-West region of Brazil, data on candidemia are scarce. This paper reports a retrospective analysis of 96 cases of Candida bloodstream infection at a Brazilian tertiary-care teaching hospital in the state of Mato Grosso do Sul, from January 1998 to December 2006. Demographic, clinical and laboratory data were collected from medical records and from the hospital's laboratory database. Patients' ages ranged from three days to 92 years, with 53 (55.2%) adults and 43 (44.8%) children. Of the latter, 25 (58.1%) were newborns. The risk conditions most often found were: long period of hospitalization, utilization of venous central catheter, and previous use of antibiotics. Fifty-eight (60.4%) patients died during the hospitalization period and eight (13.7%) of them died 30 days after the diagnosis of candidemia. Candida albicans (45.8%) was the most prevalent species, followed by C. parapsilosis (34.4%), C. tropicalis (14.6%) and C. glabrata (5.2%). This is the first report of Candida bloodstream infection in the state of Mato Grosso do Sul and it highlights the importance of considering the possibility of invasive Candida infection in patients exposed to risk factors, particularly among neonates and the elderly.

SOIL CONTAMINATION IN PUBLIC SQUARES IN BELO HORIZONTE, MINAS GERAIS, BY CANINE PARASITES IN DIFFERENT DEVELOPMENTAL STAGES

SUMMARY To evaluate soil contamination by parasites in different developmental stages in public squares used as recreation and leisure areas for children in Belo Horizonte (MG, Brazil), 210 soil samples and 141 canine fecal samples were collected from 42 squares in the city. These samples were analyzed by the Caldwell and Caldwell technique and the Hoffman, Pons, and Janer technique. Of the samples analyzed, 89 (42.4%) soil samples and 104 (73.5%) fecal samples were contaminated with Ancylostoma sp., Toxocara sp., Trichuris sp., or Dipylidium sp. eggs; Giardia sp. cysts; or Isospora sp. oocysts. The commonest parasite was Ancylostoma sp., found in 85% soil and 99% fecal samples, followed by Toxocara sp., found in 43.7% soil and 30.7% fecal samples.

DETECTION OF Leptospira spp. AND Brucella abortus ANTIBODIES IN FREE-LIVING JAGUARS (Panthera onca) IN TWO PROTECTED AREAS OF NORTHERN PANTANAL, BRAZIL

 This study aimed to assess the exposure of free-living jaguars (Panthera onca) to Leptospira spp. and Brucella abortus in two conservation units in the Pantanal of Mato Grosso, Brazil. The presence of antibodies in blood samples of eleven jaguars was investigated using autochthonous antigens isolated in Brazil added to reference antigen collection applied to diagnosis of leptospirosis by Microscopic Agglutination Test (MAT). The Rose Bengal test was applied for B. abortus antibodies. Two (18.2%) jaguars were seroreactive for the Leptospira spp. antigen and the serovar considered as most infective in both animals was a Brazilian isolate of serovar Canicola (L01). All jaguars were seronegative for B. abortus. These data indicate that the inclusion of autochthonous antigens in serological studies can significantly increase the number of reactive animals, as well as modify the epidemiological profile of Leptospira spp. infection.

Locally Advanced and Metastatic Prostate Cancer Treated with Intermittent Androgen Monotherapy or Maximal Androgen Blockade: Results from a Randomised Phase 3 Study by the South European Uroncological Group

BACKGROUND: Few randomised studies have compared antiandrogen intermittent hormonal therapy (IHT) with continuous maximal androgen blockade (MAB) therapy for advanced prostate cancer (PCa). OBJECTIVE: To determine whether overall survival (OS) on IHT (cyproterone acetate; CPA) is noninferior to OS on continuous MAB. DESIGN, SETTING, AND PARTICIPANTS: This phase 3 randomised trial compared IHT and continuous MAB in patients with locally advanced or metastatic PCa. INTERVENTION: During induction, patients received CPA 200 mg/d for 2 wk and then monthly depot injections of a luteinising hormone-releasing hormone (LHRH; triptoreline 11.25 mg) analogue plus CPA 200 mg/d. Patients whose prostate-specific antigen (PSA) was <4 ng/ml after 3 mo of induction treatment were randomised to the IHT arm (stopped treatment and restarted on CPA 300 mg/d monotherapy if PSA rose to ≥20 ng/ml or they were symptomatic) or the continuous arm (CPA 200 mg/d plus monthly LHRH analogue). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome measurement was OS. Secondary outcomes included cause-specific survival, time to subjective or objective progression, and quality of life. Time off therapy in the intermittent arm was recorded. RESULTS AND LIMITATIONS: We recruited 1045 patients, of which 918 responded to induction therapy and were randomised (462 to IHT and 456 to continuous MAB). OS was similar between groups (p=0.25), and noninferiority of IHT was demonstrated (hazard ratio [HR]: 0.90; 95% confidence interval [CI], 0.76-1.07). There was a trend for an interaction between PSA and treatment (p=0.05), favouring IHT over continuous therapy in patients with PSA ≤1 ng/ml (HR: 0.79; 95% CI, 0.61-1.02). Men treated with IHT reported better sexual function. Among the 462 patients on IHT, 50% and 28% of patients were off therapy for ≥2.5 yr or >5 yr, respectively, after randomisation. The main limitation is that the length of time for the trial to mature means that other therapies are now available. A second limitation is that T3 patients may now profit from watchful waiting instead of androgen-deprivation therapy. CONCLUSIONS: Noninferiority of IHT in terms of survival and its association with better sexual activity than continuous therapy suggest that IHT should be considered for use in routine clinical practice.

Environmental contamination by Toxocara sp eggs in public areas of Salvador, Bahia state, Brazil

A survey ofparasite eggs and cysts in soil and dog feces collected in public places of 23 boroughs of Salvador, a city in the Northeast of Brazil, was performed. High degree of contamination by Toxocara sp eggs was observed in all boroughs studied; other parasites found included: Ascaris lumbricoides, hookworms, whipworms and protozoan cysts. Parks andpublic gardens were more contaminated than streets and beachesfor all parasites, including Toxocara sp.

Atherogenesis and atherosclerosis in primary antiphospholipid syndrome

ABSTRACT: In the late seventies the term “Haematological Stress Syndrome” defined some haematological abnormalities appearing in the course of acute and chronic disorders, such as raised plasma levels of fibrinogen (FNG) and factor VIII, reduced fibrinolytic activity and hyperviscosity. In the early nineties the “Membrane stress syndrome hypothesis” proposed the unification of the concepts of haematological stress syndrome with those of oxidation, inflammation and immune activation to explain the pathogenesis of the antiphospholipid syndrome (APS) Antiphospholipid antibodies, coagulation, fibrinolysis and thrombosis. This chapter investigated the occurrence of the “Haematological Stress Syndrome” and thrombosis in 144 participants positive for aPL detected by clotting and immune tests. Among the clotting assays for the detection of lupus anticoagulant, dilute Russell's viper venom time better correlated with a history of venous thrombosis than activated partial thromboplastin time (p<0.0002 vs p<0.009) and was the only test correlated with a history of arterial thrombosis (p<0.01). By regression analysis, serum levels of IgG anticardiolipin antibodies (aCL) associated with the number of venous occlusions (p<0.001). With regards to FNG and von Willebrand factor (vWF), the former rose by 36% (95% CI; 21%, 53%) and the latter by 50% (95% CI; 29%, 75%) at the first venous occlusion and remained unchanged after subsequent occlusions. At variance FNG rose by 45% (95% CI; 31%, 60%) per arterial occlusion and vWF by 27% (95% CI; 10%, 47%) per arterial occlusion throughout. The coagulation/fibrinolytic balance was cross-sectionally evaluated on 18 thrombotic PAPS patients, 18 subjects with persistence of idiopathic aPL and in healthy controls. Markers of thrombin generation prothrombin fragment 1+2 (F1+2), thrombin-antithrombin complex (TAT) and of fibrin turnover D-Dimer (D-D) were higher in thrombotic (p=0.006)and non-thrombotic subjects (p=0.0001) than in controls as were those of D-D (p<0.0001 and p=0.003 respectively). TAT levels did not differ. Gender analysed data revealed blunted tPA release (hence a negative venous occlusion test) in thrombotic females but neither in thrombotic males (p=0.01) nor in asymptomatic subjects of either sex. Also, in both patient groups females had higher mean PAI than males (p<0.0002) and control females (p<0.02). The activity of factor XIII (FXIIIa) was evaluated was evaluated in 29 patients with PAPS, 14 persistent carriers of aPL without thrombosis, 24 thrombotic patients with inherited thrombophilia, 28 healthy controls and 32 patients with mitral and aortic valve prosthesis as controls for FXIII only. FXIIIa was highest in PAPS (p=0.001), particularly in patients with multiple (n=12) than single occlusion (p=0.02) and in correlation with PAI (p=0.003) and FNG (p=0.005). Moreover FXIIIa was strongly associated with IgG aCL and IgG anti-2GPI (p=0.005 for both) in the PAPS group and to a lesser degree in the aPL group (FXIIIa with IgG aCL, p=0.02, with IgG anti-2GPI, p=0.04). Altogether these results indicate: 1) a differential relationship of aPL, vWF and FNG with venous and arterial thrombosis; 2) heightened thrombin generation, accelerated fibrin turnover and fibrinolysis abnormalities also in asymptomatic carriers of aPLs; 3) enhanced FXIIIa that may contribute to atherothrombosis via increased fibrin/fibrinogen cross-linking. Lipid profile, lipid peroxidation and anti-lipoprotein antibodies in thrombotic primary antiphospholipid syndrome. Given the atherogenic lipid profile of SLE, the same possibility was explored in PAPS by comparing high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (CHO), apolipoprotein AI (ApoAI), apolipoprotein B (ApoB), triglycerides (TG), anti-lipoprotein antibodies, beta-2-glycoprotein I complexed to oxidized low-density lipoprotein (oxLDL-2GPI) and C-reactive protein (CRP) in 34 thrombotic PAPS patients compared to 36 thrombotic patients with inherited thrombophilia (IT), to 18 subjects persistently positive for antiphospholipid antibodies (aPL) with no underlying autoimmune or non-autoimmune disorders and to 28 healthy controls. Average concentrations of HDL (p<0.0001), LDL (p<0.0001), CHO (p=0.0002), ApoAI (p=0.002) were lower in PAPS whereas average TRY was higher (p=0.01) than other groups. Moreover PAPS showed higher IgG anti-HDL (p=0.01) and IgG anti-ApoAI (p<0.0001) as well as greater average oxLDL-2GPI (p=0.001) and CRP (p=0.003). Within PAPS, IgG anti-HDL correlated negatively to HDL (p=0.004) and was an independent predictor of oxLDL-2GPI (p=0.009). HDL and ApoAI correlated negatively with CRP (p=0.001 and p=0.007, respectively). IgG anti-HDL may hamper the antioxidant and anti-inflammatory effect of HDL favouring low-grade inflammation and enhanced oxidation in thrombotic PAPS. Indeed plasma 8-epi-prostaglandin F2α (a very specific marker of lipid peroxidation) was significantly higher in 10 patients with PAPS than 10 age and sex matched healthy subjects (p=0.0002) and strongly related to the titre of plasma IgG aCL (r=0.89, p=0.0004). Hence oxidative stress, a major player in atherogenesis, also characterises PAPS. Nitric oxide and nitrative stress in thrombotic primary antiphosholipid syndrome. Oxidative stress goes hand in hand with nitrative stress and to address the latter plasma nitrotyrosine (NT, marker of nitrative stress), nitrite (NO2-) and nitrate (NO3-) were measured in 46 thrombotic PAPS patients, 21 asymptomatic but persistent carriers of antiphospholipid antibodies (PCaPL), 38 patients with inherited thrombophilia (IT), 33 patients with systemic lupus erythematosus (SLE) and 29 healthy controls (CTR). Average crude NT was higher in PAPS and SLE (p=0.01) whereas average plasma NO2- was lower in PAPS and average NO3- highest in SLE (p<0.0001). In PAPS, IgG aCL titer and number of vascular occlusions negatively predicted NO2-, (p=0.03 and p=0.001, respectively) whereas arterial occlusions and smoking positively predicted NO3- (p=0.05 and p=0.005). Moreover CRP (an inflammatory marker) positively predicted NT (p=0.004). Nitric oxide metabolites relates to type and number of vascular occlusions and to aPL titers, whereas nitrative stress relates to low grade marker) positively predicted NT (p=0.004). Nitric oxide metabolites relates to type and number of vascular occlusions and to aPL titers, whereas nitrative stress relates to low grade inflammation and both phenomena may have implications for thrombosis and atherosclerosis in PAPS Inflammation and immune activation in thrombotic primary antiphospholipid syndrome. To investigate inflammation and immune activation in thrombotic PAPS high-sensitivity CRP (hs-CRP), serum amyloid A (SAA), oxLDL-2GPI, CRP bound to oxLDL-2GPI (CRP-oxLDL-2GPI) (as inflammatory markers) neopterin (NPT) and soluble CD14 (sCD14) (as immune activation markers) were measured by ELISA in 41 PAPS patients, in 44 patients with inherited thrombophilia (IT) and 39 controls (CTR). Compared to other groups, PAPS presented with higher plasma concentrations of inflammatory, hs-CRP (p=0.0004), SAA (p<0.01), CRP-oxLDL-2GPI (p=0.0004) and immune activation markers, NPT (p<0.0001) and sCD14 (p=0.007). By regression analysis SAA independently predicted thrombosis number (p=0.003) and NPT independently predicted thrombosis type (arterial, p=0.03) and number (p=0.04). These data confirm that low-grade inflammation and immune activation occur and relate to vascular features of PAPS. Antiphosholipid antibodies, haemostatic variables and atherosclerosis in thrombotic primary antiphospholipid syndrome To evaluate whether IgG aCL titre, haemostatic variables and the lipid profile bore any relationship to the intima media thickness (IMT) of carotid arteries high-resolution sonography was applied to the common carotid (CC), carotid bifurcation (CB) and internal carotid (IC) of 42 aPL subjects, 29 with primary thrombotic antiphospholipid syndrome and 13 with persistence of aPL in the absence of any underlying disorder. The following were measured: plasma FNG, vWF, PAI, homocysteine (HC), CHO, TG, HDL, LDL, platelet numbers and aCL of IgG and IgM isotype. By multiple regression analysis, IgG aCL titre independently predicted IMT at all carotid segments examined (p always <0.005). Plasma FNG and HC independently predicted IMT at the CB (p=0.001 and p<0.0001, respectively) and IC (p=0.03 and p<0.0001, respectively). These data strongly support an atherogenic role for IgG aCL in patients with aPL in addition to traditional risk factors. The atherosclerosis hypothesis was investigated in an age and sex-matched case-double-control study including 49 thrombotic PAPS patients (18 M, 31 F, mean age 37 ± 11), 49 thrombotic patients for IT and 49 healthy subjects. Average IMT was always greater in PAPS than control patients (CC: p=0.004, CB: p=0.013, IC: p=0.001). By dividing participants into age tertiles the IMT was greater in the second (CC: p=0.003, CB: p=0.023, IC: p=0.003) and third tertiles (CC: p=0.03, CB: p=0.004, IC: p=0.007). Conclusion: Coagulation activation, fibrinolysis depression, hightened fibrin turnover, oxidative and nitrative stress in parallel with low grade inflammation and immune activation characterise thrombotic PAPS: all these are early atherogenic processes and contribute to the demonstrated premature atherosclerosis that should be considered a clinical feature of PAPS.

Avaliação de preparações antigênicas de Strongyloides stercoralis para o imunodiagnóstico da estrongiloidíase

Preparações antigênicas de Strongyloides stercoralis para o imunodiagnóstico da estrongiloidíase têm sido tradicionalmente obtidas pela extração de antígenos do parasita com solução salina. No presente trabalho, após obtenção da preparação antigênica de S. stercoralis com extração salina, a fração residual foi solubilizada com uréia, e as duas preparações foram avaliadas para o imunodiagnóstico da estrongiloidíase, através de uma técnica imunoenzimática. Não foram encontradas diferenças significativas entre as duas preparações, em termos de atividade antigência específica e reatividade cruzada. A dificuldade de obtenção de larvas de S. stercoralis tem sido um fator limitante para o desenvolvimento de reações mais sensíveis e específicas que possam ser empregadas no imunodiagnóstico da estrongiloidíase. A possibilidade de um maior rendimento, em termos de material antigênico ativo, abre perspectivas de fracionamento do extrato bruto do parasita, na tentativa de se encontrar frações com maior atividade antigênica específica e menor reatividade cruzada.

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.

Prevalência de helmintos intestinais em três mesorregiões do Estado de Minas Gerais

Foi realizado um levantamento das helmintoses intestinais em 18.973 escolares do primeiro grau (7 a 14 anos), da rede pública do Estado de Minas Gerais, utilizando o método de Kato-Katz de exame de fezes (duas lâminas por amostra). Foram estudadas 3 mesorregiões: Triângulo Mineiro/Alto Paranaíba (60 municípios), Noroeste de Minas (13) e Sul/Sudoeste (144). Entre os escolares examinados, 15.545 (82%) estavam negativos, 2.863 (15%) monoparasitados e 565 (3%) poliparasitados. A prevalência de A. lumbricoides foi de 10,3%, de T. trichiura 4,7%, de ancilostomídeos 2,9%, de E. vermicularis 1,2%, de H. nana 0,4% e de Taenia sp 0,2%. As maiores prevalências de helmintos/mesorregião foram de 24,2% para T. trichiura e 18,7% para A. lumbricoides (Sul/Sudoeste) e 12,1% para ancilostomídeos e 0,7% para Taenia sp (Noroeste de Minas). As helmintoses intestinais continuam sendo um grave problema de saúde pública, inclusive em áreas onde as condições socioeconômicas são mais favoráveis.
