Evaluation of nonadherence to treatment among patients with schizophrenia attending psychosocial care centers in the south region of Brazil.

INTRODUCTION: The treatment of schizophrenia aims to reduce symptoms, improve quality of life and promote recovery from debilitating effects. Nonadherence to treatment is related to several factors and may lead to persistence of symptoms and relapse. Worldwide, the rate of nonadherence to treatment in individuals with schizophrenia is around 50%. OBJECTIVES: To compare the clinical profile of nonadherent and adherent patients among individuals diagnosed with schizophrenia receiving treatment at psychosocial care centers in a city in southern Brazil. METHOD: The clinical-epidemiological profile of patients with schizophrenia was retrospectively analyzed based on medical records entered into the system between January and December 2016, evaluating data at one-year follow-up. RESULTS: 112 patients were included. The disease was more prevalent in men; mean age was 40.5 years, being lower among men. Most of the sample had a low level of education, was unemployed/retired, did not have children and resided with relatives. The highest rate of diagnosis was among young adults. Psychotic symptoms were most frequently described, and the most commonly prescribed antipsychotic was haloperidol. The nonadherence rate was 15.2%; only one patient required admission to a psychiatric hospital. Among nonadherent patients, the mean time of attendance was 6 months; there were more nonadherent women than men. The most prevalent age range of nonadherence was 41-64 years. Psychosocial and clinical data were similar across the whole sample. CONCLUSION: A nonadherence rate of 15.2% was found among individuals receiving treatment for schizophrenia, suggesting that psychosocial care centers were effective in treating and monitoring these patients.

Olfactory impairment in frontotemporal dementia: A systematic review and meta-analysis.

Frontotemporal dementia (FTD) presents clinically in three variants: one behavioral and two with progressive primary aphasia - non-fluent/agrammatic and semantic. Defined by the degenerative process and cerebral atrophy, olfactory dysfunction occurs in up to 96% of previous FTD case series. OBJECTIVE: the present study aims to critically synthesize data about the relationship between FTD and olfactory impairment to analyze the usefulness of olfactory evaluation tests as a complementary element in early diagnosis. METHODS: a database search was performed using the keywords "olfactory OR smell OR olfaction AND frontotemporal dementia". We included studies that evaluated olfactory function in patients diagnosed with frontotemporal dementia, all subtypes, compared with age-matched healthy controls. For comparative purposes, the effect size was calculated using Cohen's D. The studies selected were categorized according to dementia variant and olfactory test type. A meta-analysis was performed using forest plots - homogeneity was evaluated by statistical tests (i2 and Cochran Q). RESULTS: ten articles met the inclusion criteria. Heterogeneity was classified as low for semantic dementia olfactory identification and behavioral variant olfactory discrimination groups (i2 = 0 and 3.4%, respectively) and as moderate for the behavioral variant olfactory identification group (i2 = 32.6%). CONCLUSION: patients with the frontotemporal dementia behavioral variant seem to present with alterations in odor identification, but with preserved discrimination. Scent identification also seems to be impaired in semantic dementia. Therefore, we conclude that olfactory evaluation in these patients is possibly impacted by cognitive alterations and not by sensory deficits. Application of olfactory tests may prove important in differentiating prodromal states from other types of dementia with more pronounced olfactory impairment.

A demência frontotemporal apresenta-se clinicamente em três variantes: uma comportamental e duas com afasia progressiva primária - não fluente/agramática e semântica. Definida pelo processo degenerativo e atrofia cerebral, apresenta uma prevalência de disfunção olfatória de até 96% em séries anteriores. OBJETIVO: o presente estudo objetiva sintetizar criticamente dados sobre a relação entre DFT e o comprometimento olfatório para analisar a utilidade dos testes de avaliação olfatória como elemento complementar no diagnóstico precoce. MÉTODOS: uma pesquisa de banco de dados foi realizada usando as palavras-chave "olfactory OR smell OR olfaction AND frontotemporal dementia". Foram incluídos estudos que avaliaram a função olfatória em pacientes com diagnóstico de demência frontotemporal, todos os subtipos, em comparação com controles saudáveis ​​pareados por idade. Para fins de comparação, o tamanho do efeito foi calculado usando D de Cohen. Os estudos selecionados foram separados por variante de demência e tipo de teste olfativo. Uma meta-análise foi realizada utilizando gráficos floresta - sua homogeneidade foi avaliada por testes estatísticos (i2 e Cochran Q). RESULTADOS: dez artigos preencheram os critérios de inclusão. A heterogeneidade foi classificada como baixa para os grupos de identificação olfatória em demência semântica e discriminação olfatória em variante comportamental (i2 = 0 e 3.4%, respectivamente) e moderada para identificação olfatória no grupo de variante comportamental (i2 = 32.6%). CONCLUSÃO: pacientes com variante comportamental de demência frontotemporal parecem apresentar alterações na identificação de odores, com discriminação preservada. A identificação de odores parece estar prejudicada, também, na demência semântica. Desta forma, concluímos que a avaliação olfatória nesses pacientes é possivelmente impactada por alterações cognitivas e não por déficits sensoriais propriamente. A aplicação de testes olfatórios pode ser importante na diferenciação de estados prodrômicos de outros tipos de demência com comprometimento olfatório mais pronunciado.

Testes de rastreio para alterações psiquiátricas em esclerose múltipla - Revisão sistemática com metanálise / Screening tools for psychiatric disorders in multiple sclerosis - Systematic review and metanalysis

RESUMO Objetivo Realizar uma revisão sistemática com metanálise visando evidenciar as ferramentas de rastreio psiquiátrico mais adequadas na abordagem de pacientes adultos com esclerose múltipla avaliadas por estudos de acurácia diagnóstica. Métodos As bases de dados Medline, SciELO, PubMed e Lilacs foram utilizadas para pesquisa de artigos referentes ao tema proposto. Para essa busca, foram utilizados os termos " multiple sclerosis psychiatric symptoms " e " multiple sclerosis psychiatric screening ", sendo incluídos artigos na língua portuguesa e inglesa publicados entre 2007 e 2017. A qualidade dos estudos incluídos foi avaliada utilizando o método QUADAS. Uma metanálise foi conduzida com o auxílio do programa RevMan 5.3. Resultados Sete artigos foram selecionados para análise. A concordância dos revisores foi calculada com um kappa de 0,95. A maioria dos estudos selecionados realizou avaliação de ferramentas de rastreio para depressão, tendo apenas dois deles abordado a busca de transtornos de ansiedade. O rastreio de transtorno depressivo foi realizado a partir da avaliação de 11 instrumentos diferentes, enquanto o de ansiedade, por apenas dois. A maior parte dos testes analisados apresentou boa acurácia, e a ferramenta BAI foi a única com desempenho regular na análise da curva ROC (0,77 de área sob a curva). Os demais testes apresentaram desempenho bom ou excelente, cursando com mais de 83% na avaliação de área sob a curva. Conclusões As ferramentas HADS ( Hospital Anxiety and Depression Scale ), CESD ( Center for Epidemiological Scale - Depression ) e PHQ-9 ( Patient Health Questionnaire-9 ) parecem ser as mais indicadas para o rastreio psiquiátrico de pacientes com esclerose múltipla.

ABSTRACT Objective To conduct a systematic review with meta-analysis aimed to highlight the most appropriate psychiatric screening tools for clinical approach of multiple sclerosis adult patients evaluated by diagnostic accuracy studies. Methods Medline, SciELO, PubMed e Lilacs databases were searched using the terms "multiple sclerosis psychiatric symptoms" and "multiple sclerosis psychiatric screening" for articles related to the proposed theme. Articles in Portuguese and English language published between 2007 and 2017 were included. The quality of included studies was assessed using the QUADAS method. A meta-analysis was conducted using RevMan 5.3. Results Seven papers were selected for analysis. The reviewers' rating were in agreement with a 0.95 kappa. Most of the selected studies performed screening tools for depression, with only two of them addressing the search for anxiety disorders. Screening for depressive disorder was performed by the evaluation of 11 different instruments, while anxiety by only two. Most of the tests presented good accuracy - the BAI tool was the only one with a regular performance in the ROC analysis (0.77 AUC). The other tests presented with good or excellent performance, presenting more than 83% in the evaluation of AUC. Conclusions The HADS (Hospital Anxiety and Depression Scale), CESD (Center for Epidemiological Scale - Depression) and PHQ-9 (Patient Health Questionnaire-9) tools seem to be the most suitable for the psychiatric screening of patients with multiple sclerosis.
