ABSTRACT
ABSTRACT Institutionalization has been associated with social isolation, psychological and cognitive changes, and decreased levels of physical activity in older adults. Objectives: The aim of this study was to estimate the prevalence of dementia, mild cognitive impairment (MCI), and functional dependence in older adults dwelling in two different Brazilian long-term care facilities (LTCFs). Methods: This is a cross-sectional study with 185 older people of both sexes, aged 60 years or over, residing in two LTCFs in the city of Montes Claros-MG, Brazil. The diagnosis of MCI and dementia was performed using the Diagnostic and Statistical Manual of Mental Disorders. Results: Prevalence rates of dementia, MCI, and functional dependence in institutionalized older participants were 62.3, 15.1, and 78.9%, respectively. There was a significant reduction of the Mini-Mental State Examination scores according to the increase of the institutionalization period in LCTFs and the age of older adults (p<0.001). Conclusions: Prevalence of dementia and functional dependence of older adults residing in LTCFs exhibited higher rates compared to the other older population worldwide. A higher institutionalization period is related to a greater cognitive decline.
RESUMO A institucionalização tem sido associada ao isolamento social, a alterações psicológicas e cognitivas e à diminuição dos níveis de atividade física em idosos. Objetivos: Estimar a prevalência de demência, declínio cognitivo leve (DCL) e dependência funcional em idosos residentes em duas instituições de longa permanência (ILPI) brasileiras. Métodos: Estudo transversal com 185 idosos de ambos os sexos, com 60 anos ou mais, residentes em duas ILPI. O diagnóstico de DCL e demência foi realizado por meio do Manual Diagnóstico e Estatístico de Transtornos Mentais. Resultados: As taxas de prevalência de demência, DCL e dependência funcional em participantes idosos institucionalizados foram 62,3, 15,1 e 78,9%, respectivamente. Houve redução significativa dos escores do miniexame do estado mental de acordo com o aumento do período de institucionalização nas ILPI e a idade dos idosos (p<0,001). Conclusões: A prevalência de demência e dependência funcional de idosos residentes em ILPI foi mais elevada em comparação com outras populações idosas em todo o mundo. Um período maior de institucionalização está relacionado a maior declínio cognitivo.

ABSTRACT Objective: This study comprises a systematic review and meta-analysis that aimed to estimate the prevalence of dementia in long-term care institutions (LTCIs). Methods: We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Original transversal and longitudinal articles published until July 2020 were eligible in this review. Databases PubMed/MedLine, Web of Science, Scopus and ScienceDirect were searched. Overall prevalence and confidence intervals were estimated. Heterogeneity was calculated according to the index of heterogeneity (I2). Results: One hundred seventy-five studies were found in all databases and 19 studies were meta-analyses, resulting in an overall prevalence of 53% (CI 46-59%; p < 0.01) of demented older adults living in LTCIs. Conclusion: Prevalence of dementia is higher in older adults living in LTCIs than those living in general communities. This data shows a worrying reality that needs to be changed. There is a need for a better understanding of the elements that cause this increase in dementia in LTCFs to direct actions to improve the quality of life and health of institutionalized elderly.
RESUMO Objetivo: Esta revisão sistemática e metanálise objetiva estimar a prevalência de demência em instituições de longa permanência para idosos (ILPIs). Métodos: Utilizou-se o Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Artigos originais transversais e longitudinais publicados até julho de 2020 foram elegíveis para esta revisão. As buscas foram conduzidas por meio das bases de dados do PubMed/MedLine, Web of Science, Scopus e Science Direct. A prevalência geral e o intervalo de confiança foram estimados. A heterogeneidade foi calculada de acordo com o índice de heterogeneidade (I2). Resultados: Cento e setenta e cinco estudos foram encontrados em todas as bases de dados e 19 estudos foram analisados, resultando em uma prevalência geral de idosos com demência de 53% (IC 46-59%; p < 0,01) que habitam em ILPIs. Conclusão: A prevalência de demência é maior em idosos moradores de ILPIs que em idosos da população geral. Tal dado mostra uma realidade preocupante e que precisa ser modificada. Há necessidade de melhor entendimento dos elementos que causam esse aumento de demência nas ILPIs para direcionar ações para melhorar a qualidade de vida e a saúde dos idosos institucionalizados.

ABSTRACT
Background: Spatial navigation is a prodromal dementia marker. Exercise used alongside virtual reality improves many cognitive functions, but effects on spatial navigation are still unclear. Objective: To investigate the effect of virtual reality-based physical exercise with 2D exergames on spatial navigation in institutionalized non-robust older persons. Method: A total of 14 older persons (aged ⧠60) were randomly allocated to the exergame (EG) and active control (ACG) groups. EG performed exercises with 2D exergames, while the ACG used the same movements as the EG, but without the use of virtual reality. Spatial navigation was assessed through the Floor Maze Test, where the immediate maze time (IMT) and delayed maze time (DMT) were recorded. Results: Spatial navigation was enhanced in EG participants compared to ACG individuals. A significant (p = 0.01) IMT reduction between groups was observed, while DMT time without prior planning was significantly different at the significance threshold (p = 0.07). Conclusions: Virtual reality-based exercise improves the spatial navigation of institutionalized non-robust older persons. This study should be replicated to confirm the findings reported herein. Clinical Trial Registration: This study was registered in the Brazilian Registry of Clinical Trials (Protocol RBR-8dv3kg - https://ensaiosclinicos.gov.br/rg/RBR-8dv3kg).
ABSTRACT
OBJECTIVE AND METHOD: To investigate trends in the scientific evolution of the journal CNS & Neurological Disorders - Drug Targets in the neuroscience scope, we compared the contribution of publications between this journal and others from different geographical regions of the world. To track research output we conducted a bibliometric analysis of neuroscience research based on the SCimago Journal and Country Rank® from 2003 to 2017. Journal rankings were verified according to the following inclusion criteria: journals publishing the neuroscience scope and sub-areas; geographical location and journal trajectory. Additionally, the total number of original, peer-reviewed and conference articles was analyzed using bibliometric tools. RESULTS: Results showed that Europe, North America and the Middle East have been the greatest contributors of neuroscience publications. Nevertheless, there is a huge discrepancy in the number of journals per region. Until 2017, Europe was on top with 85 journals in the neuroscience field. Moreover, research on neuroscience displayed a swift expanding trend, with significant growth in recent years. CONCLUSION: In spite of CNS & Neurological Disorders - Drug Targets being a recent journal, it is an international journal emphasizing quality and innovations, and it is a hallmark on the scientific production in neuroscience. Research articles on the scope of the potential role of endocannabinoid systems in central appetite control and in obesity management and the potential of minocycline use in schizophrenia are paramount examples of innovation. Final results will help scientific researchers to know the current interests in neuroscience and provide useful information for further investigation and publication strategies.
