Serum autophagy-related gene 5 level in stroke patients: correlation with CD4+ T cells and cognition impairment during a 3-year follow-up

Abstract Autophagy-related gene (ATG) 5 regulates blood lipids, chronic inflammation, CD4+ T-cell differentiation, and neuronal death and is involved in post-stroke cognitive impairment. This study aimed to explore the correlation of serum ATG5 with CD4+ T cells and cognition impairment in stroke patients. Peripheral blood was collected from 180 stroke patients for serum ATG5 and T helper (Th) 1, Th2, Th17, and regulatory T (Treg) cell detection via enzyme-linked immunosorbent assays and flow cytometry. The Mini-Mental State Examination (MMSE) scale was completed at enrollment, year (Y)1, Y2, and Y3 in stroke patients. Serum ATG5 was also measured in 50 healthy controls (HCs). Serum ATG5 was elevated in stroke patients compared to HCs (P<0.001) and was positively correlated to Th2 cells (P=0.022), Th17 cells (P<0.001), and Th17/Treg ratio (P<0.001) in stroke patients but not correlated with Th1 cells, Th1/Th2 ratio, or Treg cells (all P>0.050). Serum ATG5 (P=0.037), Th1 cells (P=0.022), Th17 cells (P=0.002), and Th17/Treg ratio (P=0.018) were elevated in stroke patients with MMSE score-identified cognition impairment vs those without cognition impairment, whereas Th2 cells, Th1/Th2 ratio, and Treg cells were not different between them (all P>0.050). Importantly, serum ATG5 was negatively linked with MMSE score at enrollment (P=0.004), Y1 (P=0.002), Y2 (P=0.014), and Y3 (P=0.001); moreover, it was positively related to 2-year (P=0.024) and 3-year (P=0.012) MMSE score decline in stroke patients. Serum ATG5 was positively correlated with Th2 and Th17 cells and estimated cognitive function decline in stroke patients.

Asociación entre la salud oral y el deterioro cognitivo leve en adultos mayores

Introducción: En la medida que se incrementa la población de adultos mayores, aumenta la prevalencia, aumenta la prevalencia del deterioro cognitivo. Recientemente, se ha introducido la mala salud oral entre los factores de riesgo potenciales. Objetivo: Determinar la asociación entre la salud oral y el deterioro cognitivo leve en adultos mayores de una comunidad de la provincia de Santiago de Cuba. Métodos: Se realizó un estudio observacional, analítico y retrospectivo, de tipo casos y controles en el período comprendido entre enero y julio del año 2023. La población de estudio estuvo constituida por 257 adultos mayores que vivían en esta comunidad, de los cuales se escogieron 40 casos con diagnóstico de deterioro cognitivo leve, según los criterios de Petersen. Se seleccionaron tres controles por cada caso, 120 adultos mayores con aproximadamente las mismas características que el caso. Se precisó la fuerza de asociación de cada factor de riesgo. Resultados: Se halló una asociación significativa entre padecer deterioro cognitivo leve y presentar un número de 1 a 9 dientes. El dolor oral se presentó con mayor frecuencia en el 72,5 por ciento de los casos. No recordar la última visita al estomatólogo fue causa de deterioro cognitivo leve en el 42,5 por ciento. Cepillarse irregularmente se asoció 4,1 veces más con el riesgo de desarrollar esta afección. Conclusiones : Existe una asociación entre la salud oral y el deterioro cognitivo leve en los adultos mayores. Tener menos dientes y referir dolor oral fueron factores de riesgo importantes para presentar deterioro cognitivo. La visita al estomatólogo y el cepillado de dientes irregular influyeron negativamente en la enfermedad. Sin embargo, el uso de prótesis dentales fue un factor protector para el deterioro cognitivo leve(AU)

Introduction: Along with the increase in the population of older adults, the prevalence of cognitive impairment is increasing. Recently, poor oral health has been introduced among potential risk factors. Objective: To determine the association between oral health and mild cognitive impairment in older adults in a community in the province of Santiago de Cuba. Methods: An observational, analytical and retrospective case-control study was carried out from January to July 2023. The study population consisted of 257 older adults living in this community, from which 40 cases were selected with a diagnosis of mild cognitive impairment, according to Petersen's criteria. Three controls were selected for each case, 120 older adults with approximately the same characteristics as the case. The strength of association of each risk factor was determined. Results: A significant association was found between having mild cognitive impairment and having 1 to 9 teeth. Oral pain was more frequent in 72.5 percent of the cases. Not remembering the last visit to the dentist was a cause of mild cognitive impairment in 42.5 percent. Irregular brushing was 4.1 times more associated with the risk of developing this condition. Conclusions: There is an association between oral health and mild cognitive impairment in older adults. Having fewer teeth and reporting oral pain were important risk factors for cognitive impairment. Visiting the dentist and irregular tooth brushing had a negative influence on the disease. However, the use of dental prosthetics was a protective factor for mild cognitive impairment(AU)

Prevalence and influencing factors of mild cognitive impairment in the elderly in Songjiang District, Shanghai / 环境与职业医学

Background With the aging of China's population, cognitive impairment in the elderly is receiving increasing public attention. Screening and intervention of people with mild cognitive impairment (MCI) are of great significance to prevent and reduce the occurrence of cognitive impairment. Objective To understand the prevalence and explore potential influencing factors of MCI in the elderly in Songjiang District, Shanghai, and to provide scientific basis for promoting early screening of cognitive impairment and precise intervention of MCI in the elderly in this area. Methods A cross-sectional study design was adopted. From August to October 2022, using multi-stage random sampling, 1800 elderly residents aged 60 years and above were screened for cognitive impairment in 6 neighborhood/village committees in 6 towns in Songjiang District. The survey questionnaires included a sociodemographic questionnaire, a health status and lifestyle questionnaire, the Instrumental Activities of Daily Living (IADL), the Patient Health Questionnaire (PHQ-9), and the Mini-Mental State Examination (MMSE). Prevalence rates of MCI among the elderly by selected social demographic characteristics, health status, and lifestyle were estimated, and potential influencing factors of MCI were evaluated by binary logistic regression. Results A total of 209 elderly residents with MCI and 1591 healthy elderly residents were detected, and the prevalence of MCI in the elderly aged 60 and above was 11.6% in Songjiang District. Being physically active (OR=0.556, 95%CI: 0.399, 0.774) reduced the risk of MCI. Illiteracy (OR=1.810, 95%CI: 1.239, 2.644), primary school education level (OR=3.454, 95%CI: 2.342, 5.092), non-participation in social activities (OR=1.945, 95%CI: 1.360, 2.781), IADL damaged (OR=3.173, 95%CI: 2.137, 4.712), and depression (OR=1.957, 95%CI: 1.112, 3.443) increased the risk of MCI (P＜0.05). Conclusion The prevalence of MCI among the elderly in Songjiang District is lower than the national average. Educational level, physical activity, participation in social activities, IADL, and depression may be the influencing factors of MCI in the elderly. It is recommended to carry out early screening, early detection, and early intervention for cognitive impairment in the elderly. Improving involvement in physical exercise and increasing participation in social activities are encouraged. Special attention should be paid to the needs of vulnerable groups such as low education level and disabled elderly during a community MCI intervention program.

Effect of transcranial direct current stimulation on cognitive function and quality of life in patients with Parkinson's disease: a meta-analysis / 中国康复理论与实践

ObjectiveTo evaluate the effect of transcranial direct current stimulation (tDCS) on the cognitive function and quality of life in patients with Parkinson's disease. MethodsRandomized controlled trials (RCTs) on tDCS for Parkinson's disease were searched in PubMed, Web of Science, Embase, Cochrane Library, CNKI, CBM, VIP and Wanfang Data from the inception to September, 2023. Control group was administered standard Parkinson's medications or placebo, physical therapy, and cognitive rehabilitation, while treatment group received tDCS additionally. The quality of the researches was evaluated using the Cochrane Risk of Bias Tool. Data synthesis and analysis were performed using RevMan 5.4 and Stata 17.0, with heterogeneity and sensitivity analyses. ResultsEight articles were included. tDCS significantly improved the scores of Montreal Cognitive Assessment (MD = 2.00, 95%CI 1.13 to 2.87, P < 0.001). However, there was no significant difference in the scores of Parkinson's Disease Questionnaire (MD = 0.73, 95%CI -5.78 to 7.23, P = 0.830), Beck Depression Inventory-Ⅱ(MD = -0.77, 95%CI -7.14 to 5.60, P = 0.810), and Unified Parkinson Disease Rating Scale-Ⅲ (MD = 1.60, 95%CI -0.77 to 3.97, P = 0.190). ConclusiontDCS may improve cognitive function of patients with Parkinson's disease.

Impact of subjective vertical perception impairment on function in stroke patients: a retrospective study / 中国康复理论与实践

ObjectiveTo explore the impact of subjective vertical perception impairment after stroke on visuospatial cognition, balance, walking and activities of daily living, to investigate the mediating role of visuospatial cognition and lateropulsion. MethodsFrom February to December, 2023, 96 stroke patients were selected from the Rehabilitation Medicine Center of the First Affiliated Hospital of Nanjing Medical University. They were divided into vertical perception impairment group (n = 53) and non-vertical perception impairment group (n = 43). They were assessed with National Institutes of Health Stroke Scale (NIHSS), the Scale for Contraversive Pushing (SCP), Burke Lateropulsion Scale (BLS), Line Bisection Test (LBT), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Subjective Visual Vertical (SVV), Berg Balance Scale (BBS), Holden Functional Ambulation Categories (FAC) and Barthel Index (BI). ResultsScores of SVV orientation, SVV uncertainty, NIHSS, SCT, SCP, BLS, BBS, FAC and BI were worse in the vertical perception impairment group than in the non-vertical perception impairment group (|t| > 2.414, Z = -3.481, P < 0.05). Scores of SVV were correlated with SCT, BLS and BBS (|r| ≥ 0.273, P < 0.05). After controlling for age and gender, SVV orientation score did not directly impact BBS score (β = -0.011, P = 0.920). However, it exerted a partial mediating effect through BLS (effect = -0.173, 95%CI -0.278 to -0.076) and a chain-mediated effect through SCT and BLS (effect = -0.073, 95%CI -0.137 to -0.027), impacting BBS score. ConclusionSubjective vertical perception impairment results in poorer visuospatial cognition, balance, walking and activities of daily living in stroke patients. This influence on balance function is mediated through the mediating effects of visuospatial cognition and lateropulsion.

Effects of long-term noise exposure during sleep on cognitive function and biological clock-related mechanisms in mice / 环境与职业医学

Background Environmental noise pollution is serious, and there are few studies on the effects of long-term noise exposure during sleep on cognitive function and possible biological clock mechanism. Objective To explore the cognitive impairment induced by noise exposure during sleep in mice and possible biological clock mechanism, and to provide a theoretical basis for the protection against noise exposure. Methods Twenty male C57BL/6J mice were randomly divided into a control group and a noise-exposed group, 10 mice in each group. The noise-exposed group was exposed to sleep-period noise using a noise generator for 12 h (08:00–20:00) per day for a total of 30 d. The calibrated noise intensity was set at 90 dB. No intervention was imposed on the control group. At the end of the noise exposure, cognitive function of mice was examined using the new object recognition experiment and the open field test, and the hippocampal tissue damage of mice were evaluated by Nissl staining, ionized calcium binding adaptor molecule 1 (Iba1) immunofluorescence staining, and real-time fluorescence quantitative PCR for inflammatory factors and biological clock genes. Oxidative stress indicators in the hippocampus of mice were also detected by assay kit. Results After noise exposure during sleep period, the results of new object recognition experiment showed that the discrimination index of mice in the noise-exposed group was 0.06±0.04, which was significantly lower than that of the control group (0.65±0.13) (P<0.05). The results of open field test showed that the central activity distance of the noise-exposed group was (242.20±176.10) mm, which was significantly lower than that of the control group, (1548.00±790.30) mm (P < 0.05), and the central activity time of the noise-exposed group was (0.87±0.64) s, which was significantly lower than that of the control group, (6.00±2.86) s (P < 0.05). The Nissl staining results showed that compared with the control group, neurons in the hippocampus of the noise-exposed mice were shrunken, deeply stained, disorganized, and loosely connected. The immunofluorescence results showed that microglia in the hippocampus of the noise-exposed mice were activated and the expression of Iba1 was significantly increased compared with those of the control group (P<0.05). The real-time PCR results of showed that the mRNA levels of the biological clock genes Clock, Per2, and Rev-erbα were significantly increased compared with those of the control group (P<0.05), and the mRNA level of Per1 was significantly decreased compared with that of the control group (P<0.05); and the mRNA levels of IL-18, IL-6, iNOS, and NLRP3 in the hippocampal tissues of mice were significantly increased compared with those of the control group (P<0.05). The results of oxidative stress evaluation showed that compared with the control group, reduced glutathione content was significantly reduced in the noise-exposed group (P<0.001). Conclusion Noise exposure during sleep period can lead to the destabilization of biological clock genes in hippocampal tissues and trigger hippocampal neuroinflammation, which can lead to the activation of microglia and cause cognitive impairment in mice.

Regulating PI3K/Akt Signaling Pathway by Traditional Chinese Medicine to Improve Cognitive Impairment： A Review / 中国实验方剂学杂志

Cognitive impairment refers to the abnormality of the hippocampus， cortex and other parts of the brain， which is manifested by the decline of cognitive abilities such as learning， memory and attention. With the increase in people's work pressure and bad living habits， the incidence of cognitive impairment is getting higher and higher， which seriously affects people's normal life. However， there are adverse reactions such as gastrointestinal reactions and extrapyramidal reactions in Western drug treatment for cognitive impairment. Therefore， the development of a drug with relatively minimal adverse reactions is of great significance. Traditional Chinese medicine （TCM） has the characteristics of "multi-component， multi-pathway and multi-target"， and the incidence of adverse reactions is relatively low. Studies have shown that the pathogenesis of cognitive impairment is closely related to oxidative stress， inflammation， apoptosis， autophagy and other processes of neurons in the cerebral cortex and hippocampus. Phosphatidylinositol 3-kinase （PI3K）-protein kinase B （Akt） signal pathway plays an important role in the transmission of intracellular and intracellular signals， and in the regulation of cellular inflammation， apoptosis， autophagy， etc. TCM monomers， TCM extracts， and TCM compounds exert anti-inflammatory， antioxidant， anti-apoptotic and autophagy regulation effects by regulating the PI3K/Akt signaling pathway to improve cognitive impairment. This review first summarized the composition and regulatory process of the PI3K/Akt signaling pathway， and then discussed the research progress on the improvement of cognitive impairment through the improvement of oxidative stress， inflammation， apoptosis and autophagy of neurons. Finally， the recent research status of the regulation of this signaling pathway by TCM extracts， TCM monomers and TCM compounds to improve cognitive impairment was summarized. This study provides a theoretical basis for the future study of new TCM related to cognitive impairment.

Research Progress on Mechanisms of Triggeringreceptor Expressed on Myeloid Cells-2 in Cognitive Dysfunction / 中山大学学报(医学科学版)

The neuroimmune system is crucial for the development， aging， and damage of the central nervous system， and has gradually become a research hotspot. Triggeringreceptor expressed on myeloid cells-2 （TREM2） is a transmembrane receptor of the immunoglobulin superfamily and is mainly expressed in the microglia in the central nervous system. An increasing number of studies indicate that TREM2 has great potential to improve cognitive dysfunction related to Alzheimer's disease， vascular dementia， Parkinson's disease， postoperative cognitive impairment， obesity， etc. However， there is a lack of a systematic summary of the specific role of TREM2 in cognitive dysfunction. This paper reviews the progress in the latest research on the related mechanisms of TREM2 in cognitive dysfunction， in order to provide new strategies for the treatment of cognitive dysfunction.

Alertamientos y movimientos periódicos de las piernas durante las etapas de sueño y deterioro cognitivo leve en adultos mayores. Estudio preliminar / Arousals and periodic leg movements during sleep stages and mild cognitive impairment in older adults: a preliminary study

RESUMEN La fragmentación del sueño puede asociarse con distintas enfermedades, entre ellas, la demencia. En este sentido, la fragmentación de sueño, indicada por el índice de alertamientos y/o movimientos periódicos de las piernas (MPP), podría ser un marcador temprano de deterioro cognitivo leve (DCL), un síndrome precursor de la demencia. El objetivo del presente estudio fue medir el índice de prevalencia de los alertamientos y de los MPP durante el sueño en un grupo control y un grupo con DCL, así como determinar si hay diferencia entre los grupos en ambos índices y establecer si existe una correlación entre los dos fenómenos. En 9 participantes (3 mujeres controles y 3 mujeres con DCL; y 3 hombres con DCL) (edad: 69.1 ± 5; años de educación: 8 ± 2) se registró una noche de polisomnografía. Se obtuvieron los índices por hora de alertamientos y para cada etapa de sueño, así como los MPP globales y por hora; además se realizaron análisis entre y dentro de cada grupo. Se encontró una correlación positiva y un mayor número de MPP que de alertamientos durante toda la noche en los participantes con DCL. Conocer la prevalencia y asociación de ambos fenómenos contribuye en la formulación de una evaluación más cuidadosa y profunda de los adultos mayores en riesgo de desarrollar DCL y/o demencia.

ABSTRACT Sleep fragmentation may be associated with several diseases, including dementia. In this sense, sleep fragmentation, indicated by the rates of arousals and/or periodic leg movements (PLM), could be an early marker of Mild Cognitive Impairment (MCI), a syndromic stage prior to dementia. Therefore, the objective of this study was to compare the index of PLM with that of arousals and correlate both indexes in people with MCI and without MCI during all sleep stages. In 9 participants (3 control women and 3 women with MCI; and 3 men with MCI) (ages: 69.1 ± 5; years of education: 8 ± 2), one night of polysomnography was performed. Hourly rates of arousals and PLM were scored from each sleep stage. Analyses were performed within and between PLM and arousals for each group. Significant differences and a positive correlation were found between the arousal and the PLM rates for the group with MCI during the whole night. Knowledge of the prevalence and the association of both phenomena may contribute to a more careful and thorough evaluation of older adults at risk of developing MCI and/or dementia.

Associação entre autopercepção auditiva e comprometimento cognitivo em idosos brasileiros: estudo populacional / Association between self-perceived hearing status and cognitive impairment in the older Brazilian population: a population-based study

Resumo Saúde cognitiva é um fator importante para qualidade de vida e a autonomia dos idosos, sendo influenciada pela capacidade auditiva. O objetivo deste artigo é analisar a associação entre autopercepção auditiva e comprometimento cognitivo em idosos brasileiros. Trata-se de um estudo transversal de base populacional com 4.977 idosos que participaram do ELSI Brasil 2015. Comprometimento cognitivo (desfecho, categorizado como sim e não) e a variável de interesse (autopercepção auditiva, categorizada como boa, regular e ruim), ambos obtidos de forma autorreferida. Para a cognição foram considerados os domínios orientação temporal, memória (curto e longo prazo) e linguagem (recente e tardia). Foi utilizada a regressão de Poisson com estimativa de variância robusta para aferir a associação nas análises bruta e ajustada. Variáveis sociodemográficas, de estilo de vida e de histórico clínico foram utilizadas para ajuste das análises. Dos participantes, 31,8% relataram audição regular ou ruim e 42% apresentaram comprometimento cognitivo. Na análise ajustada, idosos com audição ruim apresentaram maior força de associação com comprometimento cognitivo, em comparação com seus pares com audição boa. Em idosos brasileiros, quanto pior a autopercepção auditiva, maior a associação com o comprometimento cognitivo.

Abstract Cognitive health plays an important role in the quality of life and autonomy of older adults. and it is influenced by hearing ability. This article aims to analyze the association between self-perceived hearing status and cognitive impairment in Brazilian older adults. This cross-sectional population-based study was conducted with 4,977 older adults who participated in ELSI Brazil 2015. The cognitive impairment status (outcome. categorized as "yes" and "no") and variable of interest (self-perceived hearing status. categorized as "good" "fair" and "poor") were obtained using a self-report method. The following domains were considered for cognition: temporal orientation. memory (short and long term). and language (recent and late). Poisson regression with robust variance estimation was used to assess the self-perceived hearing status-cognitive impairment association in the crude and adjusted analyses. Sociodemographic. lifestyle. and medical history variables were used to adjust the analyses. We found that 31.8% of the participants reported fair or poor hearing and 42% had cognitive impairment. In the adjusted analysis. older adults with poor hearing were revealed to have a stronger association with cognitive impairment than their peers with good hearing. Therefore. in older Brazilian adults. lower self-perceived hearing status is associated higher levels of cognitive impairment.

Secuelas cognitivas en encefalitis inmunomediadas: cohorte de pacientes en Argentina / Cognitive sequelae in immunomediated encephalitis: cohort of patients in Argentina

Resumen Introducción: Las encefalitis inmunomediadas son un desorden neurológico de origen autoinmune. Actual mente es escasa la descripción de las secuelas cognitivas crónicas. El objetivo del presente trabajo fue caracterizar la secuela cognitiva de diferentes tipos de encefalitis inmunomediadas en una cohorte de un centro único de Argentina. Métodos: Estudio prospectivo, observacional, trans versal, de pacientes en seguimiento en un hospital de la Ciudad de Buenos Aires, con diagnóstico de encefalitis inmunomediada probable y definitiva. Se evaluaron variables epidemiológicas, clínicas, paraclínicas y tra tamiento. Se determinó la secuela cognitiva a través de una evaluación neurocognitiva realizada a partir del año de la presentación clínica. Resultados: Fueron incluidos 15 pacientes, todos con resultado disminuido en al menos un test. La memoria fue el dominio más afectado. Aquellos que se encon traban bajo tratamiento inmunosupresor al momento de evaluarse presentaron menores resultados en el aprendizaje seriado (media -2.94; desvío estándar 1.54) versus los que se encontraban sin tratamiento (media -1.18; desvío estándar 1.40; p = 0.05) y en la prueba de reconocimiento (media -10.34; desvío estándar 8.02) ver sus sin tratamiento (media -1.39; desvío estándar 2.21; p = 0.003). Los pacientes con estatus epiléptico tuvieron resultados deficitarios en la prueba de reconocimiento (media -7.2; desvío estándar 7.91) en comparación a los que no lo tenían (media -1.47; desvío estándar 2.34; p = 0.05). Conclusión: Nuestros resultados demuestran que, a pesar del curso monofásico de la enfermedad, todos los pacientes presentan daño cognitivo persistente más allá del año del inicio del cuadro.

Abstract Introduction: Autoimmune encephalitis represents a group of immune-mediated neurological disorders. At present, the description of the chronic cognitive sequela is scarce. The objective of this study was to characterize the cognitive after effects of different types of autoimmune encephalitis in a cohort from a single center in Argentina. Methods: Prospective, observational, cross-sectional study of patients under follow-up at a hospital in Buenos Aires city, with a diagnosis of probable and definitive immune-mediated encephalitis. Epidemiological, clini cal, paraclinical and treatment related variables were evaluated. Cognitive sequela was determined through a neurocognitive evaluation performed at least a year after the clinical presentation. Results: Fifteen patients were included. All had di minished results in at least one test. Memory was the most affected domain. Patients who were under im munosuppressive treatment at the time of evaluation presented lower results in serial learning (mean -2.94; standard deviation 1.54) versus those who weren't under treatment (mean -1.18; standard deviation 1.40; p = 0.05). The same pattern was observed on the recognition test of treatment group (mean -10.34; standard deviation 8.02) versus treatment-free group (mean -1.39; standard deviation 2.21; p =0.003). Patients with status epilepticus had poorer results in the recognition test (mean -7.2; standard deviation 7.91) compared to those without it (mean -1.47; standard deviation 2.34; p = 0.05). Conclusion: Our results show that, despite the mo nophasic course of this disease, all patients had persis tent cognitive damage beyond the year of onset. Larger prospective studies are required to confirm our findings.

Pain in older adults with dementia: Brazilian validation of Pain Intensity Measure for Persons with Dementia (PIMD) / Dor em idosos com demência: validação da versão brasileira do instrumento Pain Intensity Measure for Persons with Dementia (PIMD)

Abstract Background Although there are several ways to assess pain in dementia, there is still a need for tools with better items to assess the presence of pain intensity in these individuals. Objective To validate to Brazilian version of the "Pain Intensity Measure for Persons with Dementia - PIMD-p. Methods Older adults, all demented with impaired verbal communication and exposed to potentially painful situations, were selected from an outpatient clinic and long-term care facility (LTCF). The PIMD-p was applied independently by 2 researchers (E1 and E2) on the same day. Within 14 days, the instrument was reapplied by one of the 2 researchers (E3). The pain intensity reported by participants' caregivers and LTCF nurses were recorded on a verbal numeric pain scale. For the statistical analysis, Cronbach's Alpha, Spearman's Coefficient and intraclass correlation Index were calculated. Results A total of 50 older individuals were selected (mean age 86 years), majority with musculoskeletal pain. The PIMD-p demonstrated good internal consistency according to Cronbach's α (0.838), excellent intra and interobserver reproducibility (0.927 and 0.970, respectively; p < 0.001), and convergent validity (strong significant correlations between reported pain intensities and pain indicators on the PIMD-p (except for expressive eyes; corr = 0.106 and p = 0.462). A ROC curve was plotted to determine the best cut-off for the PIMD-P, and a score of 7.5 predicted moderate-to-severe pain, with 77.8% sensitivity and 95.7% specificity (p < 0.001). Conclusion The PIMD-p showed satisfactory psychometric properties for measuring intensity of pain in demented older adults with impaired verbal communication.

Resumo Antecedentes Embora existam várias formas de estimar a dor na demência ainda há necessidade de ferramentas com melhores itens para avaliação da presença e intensidade da dor nesses indivíduos. Objetivo Analisar as propriedades psicométricas de uma ferramenta de avaliação da dor em idosos dementados, a "Pain Intensity Measure for Persons with Dementia Portuguese - PIMD-p". Métodos Idosos expostos a situações potencialmente dolorosas, sendo esses dementados e com prejuízo na comunicação verbal, foram selecionados em uma unidade ambulatorial e uma instituição de longa permanência, em São Paulo. A PIMD-p foi aplicada por 2 pesquisadores (E1 e E2), de forma separada, num mesmo dia, e, com intervalo de no máximo 14 dias, essa foi reaplicada por apenas um deles (E3), e ainda, foi obtida a intensidade álgica inferida pelos cuidadores dos idosos participantes. Na análise estatística foram utilizados o Alfa de Cronbach, o Coeficiente de Spearman e o Índice de Correlação Intraclasses. Resultados Selecionada uma amostra de 50 idosos com média de idade de 86 anos, a maioria portadora de demência moderada e de dor de origem musculoesquelética. Apuradas para a PIMD-p uma boa consistência interna, segundo o alfa Cronbach (0,838); excelentes reprodutibilidades intra e interobservador (0,927 e 0,970, respectivamente; p < 0,001); e uma validade convergente, essa última obtida com as fortes e significativas correlações entre as intensidades dolorosas inferidas e os indicadores de dor do instrumento em estudo (exceto para o indicador "olhar expressivo"; corr = 0,106 e p = 0,462). Conclusão A PIMD-p se mostrou ser uma ferramenta com propriedades de medida adequadas para avaliar a presença e intensidade álgicas em idosos com demência e com prejuízo na comunicação verbal.

A relação entre o comprometimento motor e os sintomas depressivos na doença de Parkinson / The relationship between motor impairment and depressive symptoms in Parkinson's disease

Trata-se de um estudo transversal retrospectivo que incluiu 27 pessoas com doença de Parkinson (DP), diagnosticados por neurologista. O objetivo do estudo foi analisar o tipo de correlação entre o grau de comprometimento motor e grau de depressão em pessoas com DP, tendo como hipótese que quanto maior o grau de comprometimento motor proporcionado pela doença, maior o grau de depressão. Foram utilizados os instrumentos Inventário de Depressão de Beck (BDI II) para a medida de sintomas depressivos e do grau de depressão, e a escala Hoehn & Yahr foi aplicada para identificação do grau de comprometimento motor. Foram excluídos indivíduos que não preencheram um dos instrumentos do estudo, selecionando apenas as pessoas com DP que preencheram ambos os instrumentos. Verificou-se uma correlação positiva e significativa entre os resultados do BDI -II e a escala Hoehn & Yahr modificada (r = 0,41, p = 0,035). O estudo identificou, portanto, uma associação crescente e positiva entre o grau de comprometimento motor das pessoas com DP e a presença de sintomas de depressão. Com isso, foi possível concluir que, uma pessoa com DP e maior grau de comprometimento motor, tende a apresentar maior número de sintomas depressivos e, consequentemente maior grau de depressão e vice-versa. Portanto, deve-se dedicar maior atenção à saúde mental dos casos em que a doença se expressa com maior comprometimento motor.

This is a retrospective cross-sectional study that included 27 people with Parkinson's disease (PD), diagnosed by a neurologist. The objective of the study was to analyze the type of correlation between the degree of physical impairment and degree of depression in people with PD, having as hypothesis that the greater the degree of physical impairment provided by the disease, the greater the degree of depression. The Beck Depression Inventory (BDI II) was used to measure depressive symptoms and the degree of depression, and the modified Hoehn & Yahr scale was applied to identify the degree of physical impairment. Individuals who did not complete one of the study instruments were excluded, selecting only those people with PD who completed both instruments. A positive and significant correlation can be verified between the results of the BDI -II and the Hoehn & Yahr scale (r = 0.41, p = 0.035). The study identified, therefore, an increasing and positive association between the degree of motor impairment of people with PD and the presence of symptoms of depression. With this, it was possible to conclude that, a person with PD and a higher degree of motor impairment, tends to present a higher number of depressive symptoms and, consequently, a higher level of depression and vice versa. Thus, the more physically compromised the person with PD is, the greater the association with a more severe depression. Therefore, greater attention should be paid to mental health in cases in which the disease is expressed with greater physical impairment.
