Dementia prevalence among hospitalized older patients: a multicenter study in Iran / Prevalência de demência entre pacientes idosos hospitalizados: um estudo multicêntrico no Irã

ABSTRACT Dementia poses a significant societal and health challenge in the 21st century, with many hospitalized patients experiencing dementia without a documented diagnosis. Objective: To evaluate the prevalence of dementia and its associated risk factors among older patients admitted to hospitals. Methods: The study included older patients (≥ 60 years) admitted to medical departments of a general hospital in three major Iranian cities. Researchers utilized the Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, the Geriatric Depression Scale (GDS), the Mini-Cog test, the 4 A's test (4AT), and the Abbreviated Mental Test Score (AMTS). Among the 420 recruited older inpatients, 228 (54.3%) were female. Results: The mean age of participants was 71.39 years (standard deviation ±7.95), with 30.7% diagnosed with major neurocognitive disorder (dementia). The likelihood of dementia exhibited statistically significant correlations with gender, age, number of children, and occupation. Conclusions: Screening older individuals for cognitive impairment upon hospital admission holds the potential to prevent adverse outcomes and enhance the quality of treatment for patients concurrently dealing with dementia.

RESUMO A demência representa um grande desafio social e de saúde no século 21, com muitos pacientes hospitalizados sofrendo de demência sem um diagnóstico documentado. Objetivo: Avaliar a prevalência de demência e seus fatores de risco associados entre pacientes idosos hospitalizados. Métodos: O estudo incluiu pacientes idosos (≥ 60 anos) internados em um hospital geral em três grandes cidades iranianas. Os pesquisadores utilizaram a escala de Atividades da Vida Diária-Atividades Instrumentais da Vida Diária (Activities of Daily Living-Instrumental Activities of Daily Living - ADL-IADL), a Escala de Depressão Geriátrica, o teste Mini-Cog, o teste dos 4 As (4AT) e o Pontuação do Teste Mental Abreviado (Abbreviated Mental Test Score - AMTS). Dos 420 idosos selecionados, 228 (54,3%) eram do sexo feminino. Resultados: A média de idade dos participantes foi de 71,39 anos (desvio padrão ±7,95), sendo 30,7% diagnosticados com transtorno neurocognitivo maior (demência). A probabilidade de demência apresentou correlações estatisticamente significativas com sexo, idade, número de filhos e ocupação. Conclusões: A triagem de idosos para comprometimento cognitivo na admissão hospitalar tem o potencial de prevenir resultados adversos e melhorar a qualidade do tratamento para pacientes que lidam simultaneamente com demência.

A cross-sectional study to determine the cognitive impairment and depression among elderly in a rural area of West Bengal

Background: The increase in worldwide life expectancy among the elderly is contributing to an increase in cognitive impairment (CI). A more complicated etiology makes CI an essential clinical concern for elderly patients with depression. Ageing populations as a result of demographic change have accelerated the development of certain geriatric conditions, including CI and depression. Aims and Objectives: The objective was to identify the prevalence and contributing factors of CI and depression in the elderly rural community. Materials and Methods: A descriptive, cross-sectional, and community-based study was conducted in rural field practice area of Medical College, Kolkata, among 133 geriatric people during time period of March–June, 2022. The prevalence of CI was measured using the Mini-Mental State Examination (MMSE) scale and depression was assessed using the geriatric depression scale. Data were analyzed in SPSS software version 16. Results: Mean age of the participants was 65.68 (±6.03) years. The prevalence of CI was 86.5%, with a mean MMSE score of 19.27 ± 4.34, and the depression was 77.5% and 7.07 ± 3.39. Conclusion: Almost two-third of the geriatric population is suffering from depression and CI. To handle the issue of CI, depression, and its resulting effects, new and modified geriatric health policies are very much needed.

Mental Health Screening of People Deprived of Liberty, Analyzed Through the Brief Jail Mental Health Screening (BJMHS) in Three Colombian Establishments / Tamizaje de Salud Mental de Personas Privadas de la Libertad, analizada por medio del Brief Jail Mental Health Screening (BJMHS) en tres establecimientos colombianos / Triagem de Saúde Mental de Pessoas Privadas de Liberdade, analisada através do Brief Jail Mental Health Screening (BJMHS) em três estabelecimentos colombianos

Introduction. People deprived of liberty, due to their condition and characteristics, suffer greater changes in their health than the general population, particularly in personality disorders,consumption of psychoactive substances, and suicidal tendencies. The prison system is aware of these risks, and universally, multiple approaches to the subject have been developed, as evidenced by the abundant literature, for its early detection. Objective. Apply the screening instrument, the Brief Jail Mental Health Screening (BJMHS) test, to a sample of people deprived of Liberty upon admission to three Colombian prisons, to establish the prevalence of mental health in these institutions. Methodology. The type of study was cross-sectional in a population of incarcerated individuals in three institutions, two Colombian prisons for men, and one for women, between 2019 and 2020. The final validated sample was 417 people, 22.3% women and 77.7% men, for mental health screening, applied to the admission of the population deprived of liberty in prisons. Results. The global prevalence of mental health was 46.0% with a 95% Confidence interval (41.3% to 50.8%) for the Buen Pastor prison; 46.2% with a 95% Confidence Interval (35.9% to 56.6%), for the Modelo prison 51.5% with a 95% Confidence interval (43.0% to 60.0%); and for the Picota prison with 42.0% with a 95% Confidence interval (34.9% to 49.1%). A greater impact on mental health was found in people accused or convicted of crimes against sexual freedom, integrity and training. against public safety, and against the family. Discussion. Given the unique conditions of the prison population and the universality of mental disorders, early detection of their functional level and degree of impairment is indispensable. Conclusion. The prevalence of mental health found in Colombian prisons has a similar magnitude to the same populations in various parts of the world, showing greater reliability in men than in women.

Associação da autopercepção de sentimentos depressivos e do desempenho cognitivo com a prevalência de depressão em idosos quilombolas / Association of self-perceived depressive feelings and cognitive performance with prevalence of depression among quilombola elderly people

Resumo Objetivo Analisar a associação da autopercepção de sentimentos depressivos e desempenho cognitivo comprometido com a prevalência de depressão em idosos quilombolas. Métodos Estudo transversal realizado com 168 idosos de 11 comunidades de Bequimão-MA. Foram investigadas condições socioeconômicas e de saúde, como autopercepção de sentimentos depressivos, desempenho cognitivo comprometido pelo Mini Mental (MEEM) e prevalência de depressão pela Escala de Depressão Geriátrica (GDS-30). Razões de prevalência bruta e ajustada foram calculadas com intervalo de confiança de 95% por regressão de Poisson com variância robusta. Resultados A maioria dos idosos era do sexo feminino (59,5%), tinham até 69 anos (50,6%), não tinham escolaridade (54,2%) e estavam no mais baixo estrato socioeconômico (classe E= 83,7%). O relato de sentir-se "para baixo" ou "sem perspectiva" foi feito por 45,7% dos idosos; 12,1% apresentaram desempenho cognitivo comprometido e 46,4% foram identificados com depressão pela GDS-30. Foram identificados com depressão com base na GDS-30, 65,0% dos idosos que relataram autopercepção de sentimentos depressivos, e 70% daqueles com desempenho cognitivo comprometido. Na análise ajustada por condições socioeconômicas, a depressão avaliada pela GDS-30 esteve associada à autopercepção de sentimentos depressivos (RP= 2,02; IC 95%: 1,26-3,26), mas não ao MEEM (RP= 1,64; IC 95%: 0.90-3.01). Conclusão Verificou-se alta prevalência de autopercepção de sentimentos depressivos e de depressão identificada pela GDS-30. A associação entre essas variáveis aponta para a importância da triagem e manejo da saúde mental dos idosos quilombolas.

Abstract Objective To analyze the association of self-perceived depressive feelings and cognitive performance with prevalence of depressive symptoms among quilombola elderly people. Methods Cross-sectional study conducted with elderly people from 11 communities in Bequimão-MA. Socioeconomic and health conditions, self-perception of depressive feelings, cognitive performance by the Mini-Mental State Examination (MMSE) and prevalence of depressive symptoms by the Geriatric Depression Scale (GDS-30) were investigated. Crude and adjusted prevalence ratios were calculated with a confidence interval of 95% by Poisson regression with robust variance. Results A total of 59.5% of the elderly people were females, 50.6% were up to 69 years old and 83.7% were classified in socioeconomic status E. Moreover, 45.7% reported feeling "down" or "without perspective"; 12.1% had altered cognitive performance and 46.4% were screened as depressed by the GDS-30. Based on the GDS-30, 65.0% of the elderly people reported perception of depressive feelings associated depression, as well as 70% of them showed altered cognitive performance. In the adjusted analysis, depression evaluated by the GDS-30 was associated with self-perceived depressive feelings (PR= 2.02; 95% CI: 1.26-3.26), but not with the MMSE (PR= 1.64; 95% CI: 0.90-3.01). Conclusion There was a high prevalence of self-perceived depressive feelings and depressive symptoms identified by the GDS-30. The association between these variables points to the importance of monitoring the mental health of quilombola elderly people.

Educational disparities in Brazil may interfere with the cognitive performance of Parkinson's disease patients / As disparidades educacionais brasileiras podem interferir na performance cognitiva de pacientes com doença de Parkinson

ABSTRACT. The prevalence of cognitive impairment in Parkinson's disease (PD) is about 20% to 60%. The Mini-Mental Status Examination (MMSE) is the most used cognitive screening test. Objective: To evaluate the influence of clinical and demographic characteristics, specifically the education level, on the MMSE score in PD patients of a northeast Brazilian sample. Methods: We performed a cross-sectional study of 198 PD patients at a Movement Disorders outpatient clinic in Fortaleza, CE, Brazil. Participants were assessed by detailed clinical history, modified Hoehn and Yahr staging (HY), geriatric depression scale (GDS) and MMSE. Results: We found that 68% of patients had MMSE scores below the Brazilian thresholds, which were based in Brucki et al. study (2003). There was a statistically significant difference in the bivariate analysis between educational level and cut-off classification for MMSE. More years of formal schooling were associated with more patients scoring below threshold. We found that 75%, 68.8%, and 79.7% of individuals with more than 11, 9 to 11, and 4 to 8 years of formal schooling, respectively, were below the suggested Brazilian Brucki's threshold. GDS and age were negatively correlated with total MMSE and all its domains. There was no correlation between disease duration and MMSE. Subjects with hallucinations had lower scores. Conclusion: Most of the sample had lower performance according to Brazilian thresholds, but there was no control group and no neuropsychological test in this study. Further studies in northeast Brazil are needed to review MMSE cut-off values.

RESUMO. A prevalência de comprometimento cognitivo na doença de Parkinson (DP) é de cerca de 20 a 60%. O Miniexame do Estado Mental (MEEM) é o teste de rastreio cognitivo mais utilizado. Objetivo: Avaliar a influência de características clínicas e demográficas, especificamente a escolaridade, no escore do MEEM em pacientes com DP de uma amostra do nordeste brasileiro. Métodos: Realizamos um estudo transversal com 198 pacientes com DP em um ambulatório de Distúrbios do Movimento em Fortaleza. Os participantes foram avaliados por história clínica detalhada, estadiamento modificado de Hoehn e Yahr (HY), escala de depressão geriátrica (EDG) e MEEM. Resultados: Encontramos 68% dos pacientes com escores do MEEM abaixo dos limiares brasileiros baseados em estudo de Brucki et al. (2003). Houve diferença estatisticamente significativa na análise bivariada entre a escolaridade e a classificação de corte para o MEEM. Mais anos de escolaridade foram associados a mais pacientes com pontuação abaixo do limiar. Constatamos que 75, 68,8 e 79,7% dos indivíduos com mais de 11, nove a 11 e quatro a oito anos de escolaridade, respectivamente, estavam abaixo dos limiares sugeridos pelo estudo brasileiro de Brucki et al. (2003). A EDG e a idade correlacionaram-se negativamente com o MEEM total e todos os seus domínios. Não houve correlação entre a duração da doença e o MEEM. Indivíduos com alucinações tiveram pontuações mais baixas. Conclusão: A maioria da amostra apresentou desempenho inferior aos limiares, mas não houve grupo controle e nem teste neuropsicológico neste estudo. Mais estudos no nordeste do Brasil são necessários para revisar os valores de corte do MEEM.

Galvanic vestibular stimulation to improve postural instability, voluntary attention, and quality of life in Parkinson's disease patients / Estimulação vestibular galvânica na melhora da atenção voluntária e da qualidade de vida em pacientes com doença de Parkinson e desequilíbrio corporal

ABSTRACT Galvanic vestibular stimulation (GVS) influences body balance and has proved to be useful to improve patients' mood, quality of life, and cognitive skills. This study aimed to present three cases of patients with Parkinson's disease and postural instability who had been submitted to GVS to improve their balance, by assessing the impact of this intervention on their cognition, mood, and quality of life. Patients were assessed before and after GVS sessions concerning P300 latency and scores on the 15-item Geriatric Depression Scale (GDS-15) and the 39-item quality-of-life Parkinson's Disease Questionnaire (PDQ-39). The three patients' P300 latency improved, possibly indicating improved attention. Their PDQ-39 score also improved, possibly indicating a positive impact on their quality of life. Their GDS-15 score did not change before and after the intervention. None of the patients had any intervention side effects. This three-case experimental pilot study has shown that GVS is a safe method, possibly useful to improve attention and, therefore, the quality of life of patients presented with Parkinson's disease.

RESUMO A Estimulação Vestibular Galvânica (EVG) atua no equilíbrio corporal e tem se mostrado útil na melhora do humor, da qualidade de vida e de habilidades cognitivas. O objetivo deste estudo foi apresentar três casos de pacientes com doença de Parkinson e instabilidade postural que foram submetidos à EVG para melhorar o equilíbrio e avaliar o impacto dessa intervenção na cognição, no humor e na qualidade de vida. Os pacientes foram avaliados antes e após as sessões de EVG quanto a latência do potencial evocado P300, pontuação na escala de depressão geriátrica de 15 itens (EDG-15) e pelo questionário de qualidade de vida na doença de Parkinson de 39 itens (PDQ-39). Os três pacientes apresentaram melhora na latência do P300, indicando possível melhora na atenção. Apresentaram melhora na pontuação do PDQ-39, indicando possível impacto positivo na qualidade de vida. A pontuação na EDG-15 não modificou antes e após a intervenção. Nenhum paciente apresentou efeitos colaterais decorrentes da intervenção. Com base neste estudo piloto experimental de três casos, a EVG mostrou-se um método seguro e possivelmente útil para melhorar a atenção e, consequentemente, a qualidade de vida de pacientes com doença de Parkinson.

Floor and ceiling effects on the Montreal Cognitive Assessment in patients with Parkinson's disease in Brazil / Efeitos solo e teto na Avaliação Cognitiva de Montreal em pacientes com doença de Parkinson no Brasil

ABSTRACT Parkinson's disease (PD) is a common neurodegenerative disease associated with cognitive impairment. The Montreal Cognitive Assessment (MoCA) has been used as a recommended global cognition scale for patients with PD, but there are some concerns about its application, partially due to the floor and ceiling effects. Objective: To explore the floor and ceiling effects on the MoCA in patients with PD in Brazil. Methods: Cross-sectional study with data from patients with PD from five Brazilian Movement Disorders Clinics, excluding individuals with a possible diagnosis of dementia. We analyzed the total score of the MoCA, as well as its seven cognitive domains. The floor and ceiling effects were evaluated for the total MoCA score and domains. Multivariate analyses were performed to detect factors associated with floor and ceiling effects. Results: We evaluated data from 366 patients with PD and approximately 19% of individuals had less than five years of education. For the total MoCA score, there was no floor or ceiling effect. There was a floor effect in the abstraction and delayed memory recall domains in 20% of our sample. The ceiling effect was demonstrated in all domains (80.8% more common in naming and 89% orientation), except delayed recall. Education was the main factor associated with the floor and ceiling effects, independent of region, sex, age at evaluation, and disease duration. Conclusion: The floor and ceiling effects are present in specific domains of the MoCA in Brazil, with a strong impact on education. Further adaptations of the MoCA structure for underrepresented populations may reduce these negative effects.

RESUMO A doença de Parkinson (DP) é uma doença neurodegenerativa comum associada ao declínio cognitivo. A Avaliação Cognitiva de Montreal (Montreal Cognitive Assessment — MoCA) tem sido usada como uma escala de cognição global recomendada para pacientes com DP, mas existem algumas preocupações sobre sua aplicação, em parte pelos efeitos solo e teto. Objetivo: Explorar os efeitos solo e teto na MoCA em pacientes com DP no Brasil. Métodos: Estudo transversal com dados de pacientes com DP oriundos de cinco Clínicas de Distúrbios de Movimento no Brasil, excluindo-se pessoas com possível diagnóstico de demência. Nós analisamos a pontuação total da MoCA, assim como a de seus sete domínios cognitivos. Os efeitos solo e teto foram avaliados para a pontuação total da MoCA e seus domínios. Foram feitas análises multivariadas para a detecção de fatores associados os efeitos solo e teto. Resultados: Nós avaliamos dados de 366 pacientes com DP, e aproximadamente 19% das pessoas tinham menos que cinco anos de escolaridade. Para a pontuação total do MoCA, não houve efeito solo ou teto. Houve efeito solo nos domínios abstração e memória de evocação tardia em 20% de nossa amostra. O efeito teto foi demonstrado em todos os domínios (80,8% mais comum em nomeação e 89% orientação), com exceção de memória de evocação tardia. A educação foi o principal fator associado aos efeitos solo e teto, independentemente de região, sexo, idade na avaliação e duração da doença. Conclusão: Os efeitos solo e teto estão presentes em domínios específicos da MoCA no Brasil, com forte impacto da educação. Adaptações adicionais à estrutura da MoCA para populações vulneráveis podem reduzir esses efeitos negativos.

Normalization of Rowland Universal Dementia Assessment Scale (RUDAS) in Chilean older people / Normalização da Escala Universal de Avaliação de Demência de Rowland (RUDAS) em idosos chilenos

ABSTRACT Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive screening that evaluates older people with low educational levels. In Chile, there are no normative data to assess this population. Objective: To obtain normative data on RUDAS in older Chilean people with up to 12 years of schooling, and to determine whether age and schooling years influence a person's performance on RUDAS and on the items that constitute it. Methods: A group of cognitively healthy people 60 years old or over, with up to 12 schooling years was evaluated (n=135). Multiple regression models were applied to obtain normative data on RUDAS, according to age and schooling years, and to measure the effects of schooling on different items. Results: Regression analysis showed that none of the items had schooling as a significant predictor, except for the visuoconstruction item. The variables age and schooling explained 12.6% (R^2=0.126) of the RUDAS total score variance. The item visuoconstruction was the most associated with the educational level (OR=1,147). Conclusion: This study showed that RUDAS is a recommended instrument for evaluating older people with low educational levels. However, more studies are needed to prove the validity of the RUDAS on Chilean older people.

RESUMO RUDAS é uma triagem cognitiva que avalia idosos com baixa escolaridade. No Chile não existem dados normativos para avaliar essa população. Objetivo: Obter dados normativos sobre RUDAS em idosos chilenos com até 12 anos de escolaridade. Além disso, determinar se a idade e a escolaridade influenciam o desempenho de uma pessoa no RUDAS e nos itens que o constituem. Métodos: Foi avaliado um grupo de pessoas cognitivamente saudáveis, com 60 anos ou mais e até 12 anos de escolaridade (n=135). Modelos de regressão múltipla foram utilizados para obter dados normativos do RUDAS, segundo idade e anos de escolaridade, e para mensurar os efeitos da escolaridade em diferentes itens. Resultados: A análise de regressão mostrou que nenhum dos itens teve a escolaridade como preditor significativo, exceto o item visuoconstrução. As variáveis idade e escolaridade explicam 12,6% (R^2=0,126) da variância do escore total do RUDAS. O item visuoconstrução é o mais associado ao nível de escolaridade (OR=1,147). Conclusão: Este estudo mostrou que o RUDAS é um instrumento recomendado para a avaliação de idosos com baixa escolaridade. No entanto, são necessários mais estudos para comprovar a validade do RUDAS em idosos chilenos.

45 Years of the mini-mental state examination (MMSE): A perspective from ibero-america / 45 años del mini-mental state examination (mmse): una perspectiva histórica desde iberoamérica

ABSTRACT The Mini-Mental State Examination (MMSE) was created by Marshal Folstein et al. in 1975 as an instrument for brief (5-10 min) assessment of mental status in hospitalized patients. It is considered the most widely used test for standardized cognitive assessment in the clinical setting, especially with the elderly population. It has countless translations in different languages, and according to the different international (PubMed) and regional (SciELO, Redalyc, and Dialnet) scientific databases, it has been widely used by the scientific community. This article describes the historical evolution of the MMSE, highlights its evaluative properties, and provides bibliometric data on its impact on scientific publications, with a special focus on Ibero-America.

The reliability of neurobehavioral tests in a thai adult population / A confiabilidade dos testes neurocomportamentais em uma população adulta tailandesa

ABSTRACT Early detection of decline in neurobehavioral (NB) performance requires reliable methods of testing. Although NB tests have been shown to be consistent and reliable in Western countries, there has been limited research in Asian populations. Objective: The purpose of this study was to investigate the test-retest reliability of NB tests in a Thai adult population and examine the impact of demographic data on NB tests. The aspects of the tests chosen were memory, attention, hand-eye coordination, motor speed, and dexterity. Methods: The three NB tests used were digit span, Purdue Pegboard, and visual-motor integration. All three were administered to a population of 30 Thai adults. Results: The outcomes of all Pearson's correlation coefficient tests (r) were positive and greater than 0.60, and subtest-retest reliability correlation coefficients ranged from 0.63 (p<0.001) to 0.81 (p<0.001). Interestingly, the outcomes of all of these tests were not affected by demographic data, with the exception of the Purdue Pegboard test, in which performance on the preferred hand and both hands assessment was weakly associated with age (β=-0.09, p<0.001 and β=-0.08, p<0.05, respectively). Conclusions: NB tests have adequate reliability and are useful for the evaluation of clinical memory, attention, hand-eye coordination, motor speed, and dexterity in Thai adults. These tests were not affected by demographic data. However, further studies to measure the validity of the digit span, Purdue Pegboard, and visual-motor integration tests are needed.

RESUMO A detecção precoce do declínio no desempenho neurocomportamental (NC) requer métodos confiáveis de teste. Embora os testes NC tenham se mostrado consistentes e confiáveis em países ocidentais, as pesquisas em populações asiáticas ainda são limitadas. Objetivo: O objetivo deste estudo foi investigar a confiabilidade de teste-reteste dos testes NC em uma população adulta tailandesa e o impacto dos dados demográficos nos testes NC. Os aspectos dos testes escolhidos foram memória, atenção, coordenação óculo-manual, velocidade motora e destreza. Métodos: Os três testes RC utilizados foram o digit span, o Purdue Pegboard e a integração visomotora. Todos os três foram usados em uma população de 30 adultos tailandeses. Resultados: Os resultados de todos os testes de coeficiente de correlação de Pearson (r) foram positivos e superiores a 0,60, e os coeficientes de correlação de confiabilidade subteste-reteste variaram de 0,63 (p<0,001) a 0,81 (p<0,001). Curiosamente, os resultados de todos esses testes não foram afetados pelos dados demográficos, com exceção do teste Purdue Pegboard, no qual o desempenho na mão preferida e a avaliação de ambas as mãos foi fracamente associado à idade (β=-0,09, p<0,001 e β=-0,08, p<0,05, respectivamente). Conclusão: Os testes NC apresentam confiabilidade adequada e são úteis para avaliação da memória clínica, atenção, coordenação óculo-manual, velocidade motora e destreza em adultos tailandeses. Esses testes não foram afetados por dados demográficos. No entanto, são necessários mais estudos para medir a validade dos testes de digit span, Purdue Pegboard e IVM.

ABSTRACT Background Cognitive impairment in patients with neurocysticercosis is frequent, therefore, it is very useful to have prognostic instruments to establish a better management of it. Objective to propose a predictive scale of cognitive impairment in adult patients with neurocysticercosis. Methods study with a correlational, prospective and cross-sectional design, which included 93 patients with neurocysticercosis. Through data provided by previous research, the variables were selected, which were related to the appearance of cognitive impairment in the bivariate analysis (p<0.05). As a multivariate analysis technique, a multidimensional scaling (PROXSCAL) was performed (s-stress < 0.001 and Tucker's congruence coefficient > 0.999). The prognostic performance of each of the variables was determined by means of sensitivity, specificity, and positive and negative predictive values, with their respective 9 5% confidence intervals. Results a scale with a dichotomous format was developed, which included 7 factors (4 clinical and 3 tomographic), with which a score of 0 to 7 points was obtained for the prediction of cognitive impairment in adult patients with neurocysticercosis, with a probability of: 0-1 point: 75.3 %; 2-3 points: 95 %; ≥ 4 points: 96 %. Conclusion The proposed instrument has an acceptable prognostic accuracy; it is simple, reproducible and requires little time for its application. Despite its limitations, it could improve the quality of care for patients with neurocysticercosis, since it allows guiding the management of this condition.

Cognitive impairment and elevated peripheral cytokines in breast cancer patients receiving chemotherapy / Comprometimento cognitivo e citocinas periféricas elevadas em pacientes com câncer de mama recebendo quimioterapia

Abstract Background Anthracyclines-based regimen (5-fluorouracil, doxorubicin, and cyclophosphamide (FAC); cyclophosphamide, epirubicin, and 5-fluorouracil [CEF]) and non-anthracycline based regimens (cyclophosphamide, methotrexate, and 5-fluorouracil [CMF]) are widely used as neoadjuvant chemotherapy for breast cancer patients. Objective The present study was conducted to observe the effects of FAC, CEF, and CMF regimen on cognition and circulatory proinflammatory cytokines (interleukin 6 [IL-6] and interleukin 1β [IL-1β]) for the duration of three cycles of chemotherapy in breast cancer patients. Methods Eighty newly diagnosed HER-2 negative breast cancer patients were enrolled and divided into 3 groups as FAC- (n= 27), CEF- (n= 26), and CMF- (n= 27) receiving patients. Serum IL-6 and IL-1β levels were measured by using enzyme-linked immunosorbent assay (ELISA), and cognition was assessed using the Mini-Mental State examination (MMSE) questionnaire. Results Anthracycline-based regimen was found to increase the levels of IL-6, IL-1β, and decreased MMSE scores compared with CMF regimen (p< 0.05). Conclusion Anthracycline-based regimen caused comparatively higher peripheral inflammation, which could be the reason for more decline in cognition in anthracycline-receiving patients than non-anthracycline group.

Resumo Antecedentes Regime baseado em antraciclinas (5-fluorouracil, doxorrubicina e ciclofosfamida [FAC]; ciclofosfamida, epirrubicina e 5-fluorouracil [CEF]) e regimes não baseados em antraciclina (ciclofosfamida, metotrexato e 5-fluorouracil (CMF]) são amplamente utilizados como quimioterapia neoadjuvante para pacientes com câncer de mama. Objetivo O presente estudo foi realizado para observar os efeitos do regime FAC, CEF e CMF na cognição e citocinas pró-inflamatórias circulatórias (interleucina 6 [IL-6] e interleucina 1β [IL-1β]) durante três ciclos de quimioterapia em pacientes com câncer de mama. Métodos Oitenta pacientes recém-diagnosticadas com câncer de mama HER-2 negativo foram recrutadas e divididas em 3 grupos de pacientes que receberam FAC (n= 27), CEF (n= 26) ou CMF (n= 27). Os níveis séricos de IL-6 e IL-1β foram medidos por enzyme-linked immunosorbent assay (ELISA) e a cognição foi avaliada por meio do questionário Mini-Mental State Examination (MMSE). Resultados O regime baseado em antraciclinas aumentou os níveis de IL-6, IL-1β e diminuiu os escores do MMSE em comparação com o regime CMF (p< 0,05). Conclusão O regime baseado em antraciclinas causou inflamação periférica comparativamente mais alta, o que pode ser a razão para maior declínio na cognição em pacientes que receberam antraciclinas do que no grupo que não recebeu antraciclina.

Correlación entre estado cognitivo y hallazgos tomográficos en pacientes con neurocisticercosis. Ecuador, 2019 - 2020

RESUMEN Fundamento: Muchos pacientes con neurocisticercosis manifiestan deterioro cognitivo, con afectaciones importantes en su calidad de vida. Objetivo determinar la correlación entre el estado cognitivo y los hallazgos tomográficos en pacientes con neurocisticercosis. Métodos estudio correlacional, prospectivo y transversal, que incluyó a 93 pacientes con diagnóstico de neurocisticercosis atendidos en dos hospitales ecuatorianos, desde mayo de 2019 a mayo de 2020. Para la valoración cognitiva se utilizó el Mini-Mental State Examination, de Folstein. Se estimó el riesgo relativo y la prueba de Chi cuadrado, considerando significación estadística si p<0,05. Para el análisis multivariado se utilizó un modelo de regresión logística binaria. Resultados entre los hallazgos tomográficos, se destacaron las lesiones mayores de 1 cm (32,2 %), las múltiples (30,1 %), localizadas en la región parietal (34,4 %) y las subaracnoideas (46,2 %). La evaluación cognitiva mostró resultados normales en 74,2 % de los casos, así como demencia leve a moderada en 9,7 % de los pacientes. El área más afectada fue la del lenguaje (54,8 %). La demencia se asoció principalmente con el tamaño de la lesión mayor de un 1 centímetro [RR: 7,35; IC 95 %: 1,62-33,3], seguido del número de lesiones (múltiples o racemosa) y la topografía mixta. En el análisis multivariado estas perdieron la correlación. Conclusión El déficit cognitivo tuvo una prevalencia menor a la descrita en la literatura especializada, y se asoció con variables tomográficas como el tamaño, número y localización de las lesiones; en el análisis multivariado, ninguno de estos factores mantuvo su significación estadística.

ABSTRACT Background Many patients with neurocysticercosis manifest cognitive damage, with important effects on their quality of life. Objective to determine the correlation between cognitive status and tomographic findings in patients with neurocysticercosis. Method correlational, prospective and cross-sectional study, which included 93 patients diagnosed with neurocysticercosis treated in two Ecuadorian hospitals, from May 2019 to May 2020. The Folstein Mini-Mental State Examination was used for cognitive assessment. The relative risk and the Chi square test were estimated, considering statistical significance if p<0.05. For the multivariate analysis, a binary logistic regression model was used. Results among the tomographic findings, lesions greater than 1 cm (32.2%), multiple (30.1%), located in the parietal region (34.4%) and subarachnoid (46.2%) enhance. The cognitive evaluation showed normal results in 74.2% of the cases, as well as mild to moderate dementia in 9.7% of the patients. The most affected area was the language (54.8%). Dementia was mainly associated with lesion size greater than 1 centimeter [RR: 7.35; 95% CI: 1.62-33.3], followed by the number of lesions (multiple or racemose) and the mixed topography. In the multivariate analysis, these lost the correlation. Conclusion The cognitive deficit had a lower prevalence than that described in the specialized literature, and was associated with tomographic variables such as the size, number and location of the lesions; in multivariate analysis, none of these factors maintained their statistical significance.

Changes in personality traits in patients with Alzheimer's Disease / Mudanças nos traços de personalidade em pacientes com doença de alzheimer

ABSTRACT. Changes in personality traits in patients with Alzheimer's disease (AD) are extremely common throughout the course of the pathology, and these behavioral changes present themselves as challenges in clinical management and as a significant cause of caregivers' burden. Objective: Using a personality inventory based on the five-factor model of personality, this study aimed to assesses the change in these factors by comparing the premorbid and current personality of individuals recently diagnosed with AD. Methods: A total of 30 AD patients were recruited, and their respective family members responded to the personality inventory at home through a hosted site. The patients were also divided into two groups according to the Clinical Dementia Rating (CDR): mild dementia (CDR 1) and moderate dementia (CDR 2). Results: Among all patients, there was a significant increase in neuroticism factor levels and a significant decrease in the extraversion, conscientiousness, openness, and socialization factors. When comparing the groups, only the extraversion factor showed a difference, with CDR 1 group accusing a higher change in scores. Higher scores in the factor neuroticism in the premorbid personality correlated with the current severity of the disease. Conclusions: This research draws the attention of family members and health professionals to changes in personality traits or behavior of relatives or patients, because it can reflect an underlying neurodegenerative process.

RESUMO. Mudanças em traços de personalidade em pacientes com doença de Alzheimer (DA) são extremamente comuns ao longo do curso da referida patologia, e essas alterações comportamentais apresentam-se como desafios no manejo clínico e como causa significativa de esgotamento dos cuidadores. Objetivo: Por meio de um inventário de personalidade baseado nos cinco fatores de personalidade, este estudo avalia a mudança nos escores desses fatores comparando a personalidade pré-mórbida e a atual dos indivíduos com DA. Métodos: O total de 30 pacientes com DA foi recrutado, e seus familiares responderam ao inventário de personalidade. Os pacientes também foram divididos em dois grupos conforme a avaliação clínica da demência: demência leve (CDR1) e demência moderada (CDR2). Resultados: Em todos os pacientes, houve aumento significativo nos escores do fator neuroticismo e decréscimos significativos nos fatores extroversão, realização, abertura e socialização. Quando feita a comparação entre grupos, apenas o fator extroversão apresentou diferença, com o grupo CDR 1 mostrando maiores mudanças nos escores. Os níveis do fator neuroticismo da personalidade pré-mórbida correlacionaram-se com a gravidade da doença no momento do diagnóstico. Conclusões: Este estudo procura esclarecer aos familiares e profissionais de saúde que mudanças em traços de personalidade de seus parentes ou pacientes podem refletir processos neurodegenerativos subjacentes.

Depression among and access to mental care of young Filipino ophthalmologists during the COVID-19 pandemic

Objective@#This study determined the prevalence of depression among young ophthalmologists during the COVID-19 pandemic and determined their access to mental healthcare. @*Methodology@#In this cross-sectional study, members of the Philippine Network of Young Ophthalmologists were surveyed using an online Patient Health Questionnaire-9 (PHQ-9), a short self-administered tool which included questions related to their current work to assess depression. The respondents were also asked if there was available, accessible, affordable, adequate, and acceptable mental healthcare to them answerable by yes, no, or maybe. @*Results@#Seventy (70) respondents were included in the analysis. The mean age was 33±5 years with 54% being female. Forty-five (45) or 64% were resident trainees with a mean number of years in the training of 2±1 years. The median score for the PHQ-9 was 6.5 (3,12). Forty-two (42) or 60% of the respondents had some degree of depression. Nine (9) or 13% of the respondents had no available service, 6 (9%) had no accessible service, 7 (10%) had no affordable service, and 4 (6%) had no adequate service for mental healthcare for them. @*Conclusion@#More than half of the ophthalmologists-in-training and newly practicing suffered from some degree of depression based on the PHQ-9 questionnaire. A significant proportion was either not sure or do not have available, accessible, affordable, and adequate mental healthcare services for them.

Analysis of visual scores of brain magnetic resonance imaging features of dementia with Lewy bodies / 中华老年医学杂志

Objective:To assess the practical value of visual scores of magnetic resonance imaging(MRI)features in the diagnosis and classification of dementia with Lewy bodies(DLB).Methods:In this study, 102 DLB patients were prospectively recruited, with 102 cognitively normal elderly people as the normal control group(NC).All included subjects underwent MRI examinations and neuropsychological assessments.Based on the clinical dementia rating(CDR)scale, DLB patients were divided into a mild(CDR=1.0), a moderate(CDR=2.0)and a severe(CDR=3.0)group.The results of MRI were scored visually and the rating scales included medial temporal lobe atrophy(MTA), global cortical atrophy-frontal subscale(GCA-F), posterior cortical atrophy(PCA), white matter lesions(the Fazekas scale), cerebral microbleeds(CMBs), and the Evans Index(EI).Statistical differences were compared between the DLB and NC groups and between DLB patients with different degrees of cognitive impairment.Results:In terms of neuropsychology, the Mini-Mental State Examination(MMSE) score of the DLB group[16.0(11.0, 21.0)]was statistically significantly lower than that of the NC group[29.0(28.0, 30.0)]( Z=-12.31, P<0.001), the Montreal Cognitive Assessment(MoCA)score of the DLB group[9.5(6.0, 15.0)]was statistically significantly lower than that of the NC group[28.0(27.0, 29.0)]( Z=-12.40, P<0.001), and the Activities of Daily Living(ADL)score of the DLB group[32.0(23.8, 40.0)]was statistically significantly higher than that of the NC group[20.0(20.0, 20.0)]( Z=-11.98, P<0.001).The scores of all MRI visual assessment scales in DLB patients were statistically significantly higher than those in the NC group( P<0.001).There were significant differences in MTA scores between DLB patients with different degrees of cognitive impairment( P0<0.001).The MTA score of the mild group[1.0(1.0, 1.0)]was statistically significantly lower than that of the moderate group[2.0(1.0, 2.0)]( P1<0.001, P2<0.001); The MTA score of the moderate group[2.0(1.0, 2.0)]was statistically significantly lower than that of the severe group[2.0(2.0, 3.0)]( P1=0.003, P2=0.010). Conclusions:This study has for the first time after comprehensively evaluated the value of various visual scores in DLB diagnosis, MTA can be used to help diagnose DLB and distinguish the severity of DLB, providing a new supplemental tool for clinical diagnosis.

Early and late interventional embolization can improve neurological function, mental state and living ability of patients with intracranial aneurysm / 中国基层医药

Objective:To investigate the application value of early and late interventional embolization in intracranial aneurysms.Methods:Eighty-two patients with intracranial aneurysm who received treatment in Wenzhou People's Hospital from October 2015 to February 2020 were included in this study. These patients were divided into early (≤ 3 days) and late (> 3 days) groups, with 41 patients in each group, according to time from disease onset to surgery. The early group was subjected to early interventional embolization, and the late group was treated with late interventional embolization. The effects of embolization and National Institutes of Health Stroke Scale score pre- and post-treatment, as well as modified Barthel index, Mini-Mental State Exam score, matrix metalloproteinase-9 level, and soluble intercellular adhesion molecule-1 level post-treatment and prognosis were compared between the two groups.Results:The embolization effects in the early group were statistically superior to those in the late group ( P = 0.046). After treatment, National Institutes of Health Stroke Scale score in the early group was significantly lower than that in the late group [(4.02 ± 1.64) points vs. (6.81 ± 2.02) points, t = 6.86, P < 0.01]. Mini-Mental State Exam score and modified Barthel index in the early group were (28.09 ± 1.35) points and (81.12 ± 9.67) points, respectively, which were significantly higher than (26.01 ± 1.19) points and (73.02 ± 8.19) points in the late group ( t = 7.40, 4.09, both P < 0.001). After treatment, matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels in the early group were (420.33 ± 29.40) μg/L and (403.70 ± 23.28) ug/L, respectively, which were significantly lower than (491.30 ± 31.19) μg/mL and (496.37 ± 30.46) μg/L in the late group ( t = 10.60, 15.47, both P < 0.001). Prognosis in the early group was superior to that in the late group ( P = 0.049). Conclusion:Early interventional embolization has better efficacy than late interventional embolization in the treatment of intracranial aneurysm. The former can effectively improve neurological function and mental state, enhance living ability, and improve prognosis, which may be related to the regulation of matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels.
