Pharmacotherapeutic potential of Vitis vinifera(grape) in age-related neurological diseases / Potencial farmacoterapéutico de Vitis vinifera(uva) en enfermedades neurológicas asociadas a la edad

Age-related neurological disorders (ANDs), including neurodegenerative diseases, are complex illnesses with an increasing risk with advancing years. The central nervous system's neuropathological conditions, including oxidative stress, neuroinflammation, and protein misfolding, are what define ANDs. Due to the rise in age-dependent prevalence, efforts have been made to combat ANDs. Vitis viniferahas a long history of usageto treat a variety of illness symptoms. Because multiple ligand sites may be targeted, Vitis viniferacomponents can be employed to treat ANDs. This is demonstrated by the link between the structure and action of these compounds. This review demonstrates that Vitis viniferaand its constituents, including flavonoids, phenolic compounds, stilbenoidsandaromatic acids, are effective at reducing the neurological symptoms and pathological conditions of ANDs. This is done by acting as an antioxidant and anti-inflammatory. The active Vitis vinifera ingredients have therapeutic effects on ANDs, as this review explains.

Las enfermedades neurológicas asociadas a la edad (AND, por su sigla en inglés) incluyendo las enfermedades neurodegenerativas, son enfermedades complejas con un riesgo creciente con la edad. Las condiciones neuropatológicas del sistema nervioso central, que incluyen el estrés oxidativo, la neuro inflamación, y el plegado erróneo de proteínas, son lo que define las AND. Debido al aumento en la prevalencia dependiente de la edad, se han hecho esfuerzos para combatir las AND. Vitis vinifera tiene una larga historia de uso para el tratamiento de síntomas. Puesto que puede hacer objetivo a muchos sitios ligando, los componentes de Vitis viniferase pueden utilizar para tratar AND. Esto se demuestra por el vínculo entre la estructura y la acción de estos compuestos. Esta revisión demuestra que la Vitis viniferay sus constituyentes, incluídos los flavonoides, componentes fenólicos, estilbenoides, y ácidos aromáticos, son efectivos para reducir los síntomas neurológicos y las condiciones patológicas de AND. Esto se produce por su acción como antioxidante y antiinflamatorio. Los ingredientes activos de Vitis vinifera tienen efectos terapéuticos en AND, y esta revisión lo explica.

Vulnerability Scale for People with Motor Disabilities After an Acquired Neurological Lesion / Escala de vulnerabilidade das pessoas com deficiência motora após lesão neurológica adquirida / Escala de vulnerabilidad de las personas con discapacidad motora tras una lesión neurológica adquirida

Introduction: After an acquired neurological lesion, some people are in situations of greater vulnerability to complications and comorbidities, which can exert impacts on their life and health, compromise their quality of life, and lead to hospitalizations and premature death. Identifying the vulnerability situation can guide nurses in the development of actions to prevent complications, comorbidities, and other conditions after the neurological lesion. Objective: To validate a scale to identify the vulnerability situation of people with motor disabilities after an acquired neurological lesion (Escala de Vulnerabilidade de Pessoas com Deficiência, EVU-PcD). Materials and method: The article presents a methodological development and psychometric study with a quantitative approach. The construct validity stages were as follows: application of the Vulnerability Scale for people with motor disabilities after an acquired neurological lesion (EVU-PcD) and reliability and confirmatory factor analysis. EVU-PcD, initially with 38 items, was applied to 102 individuals with acquired motor disabilities. Reliability was assessed using Cronbach's alpha from 0.7 to 0.9. In the confirmatory factor analysis, the structural equations model for latent variables a path diagram was used. Results: The overall Cronbach's alpha coefficient was 0.86, which was considered excellent. The fit indices, chi-square ratio (1.63), root mean square of approximation errors (0.08) and parsimonious fit quality index (0.61) presented acceptable indicators of adequacy to the final model with three domains and 28 items. Conclusions: The final factor structure of the EVU-PcD scale with 28 items showed satisfactory reliability and validity results to identify the vulnerability of people with motor disabilities after an acquired neurological lesion.

Uso de cannabidiol para el control de síntomas refractarios en síndromes convulsivos y enfermedades neurodegenerativas / Use of cannabidiol for the control of refractory symptoms in convulsive syndromes and neurodegenerative diseases

Como parte de las terapias alternativas para el control de síntomas refractarios en enfermedades avanzadas destaca el uso de cannabidiol. Este se ha estudiado en patologías como enfermedad de Alzheimer, Parkinson y trastornos convulsivos. Los síndromes convulsivos están presentes en todos los grupos etarios. Dentro de este, la epilepsia es refractaria hasta en un 40 % de los pacientes, quienes han demostrado disminución en la frecuencia de convulsiones con el uso concomitante de cannabidiol y antiepilépticos convencionales, con efectos secundarios leves, como diarrea y somnolencia. Con el objetivo de determinar el uso del cannabidiol para el control de síntomas neurológicos refractarios en pacientes con síndromes convulsivos y enfermedades neurodegenerativas, se realizó una búsqueda bibliográfica en Pubmed, Scopus y Embase. Se incluyeron metaanálisis, artículos originales, revisiones sistemáticas y bibliográficas, y documentos de la Organización Panamericana de la Salud, publicados entre 2017 y 2022. Los efectos del cannabidiol lo convierten en una alternativa, adicional a la terapéutica convencional, para el control de síntomas en trastornos neurológicos, disminuyendo de forma sostenida el número total de episodios con un perfil de seguridad aceptable. Existe limitada información respecto al uso de cannabidiol en enfermedades neurodegenerativas, por lo que no se ha evidenciado su efectividad

As part of the alternative therapies for the control of refractory symptoms in advanced diseases, the use of cannabidiol stands out. It has been studied in pathologies such as Alzheimer's disease, Parkinson's disease, and convulsive disorders. Convulsive syndromes are present in all age groups. Within this group, epilepsy is refractory in up to 40 % of patients, who have shown a decrease in the frequency of seizures with the concomitant use of cannabidiol and conventional antiepileptics, with mild side effects such as diarrhea and drowsiness. To determine the use of cannabidiol for the control of refractory neurological symptoms in patients with seizure syndromes and neurodegenerative diseases, a literature search was performed in PubMed, Scopus, and Embase. Meta-analyses, original articles, systematic and literature reviews, and documents from the Pan American Health Organization, published between 2017 and 2022, were included. The effects of cannabidiol make it an alternative, in addition to conventional therapeutics, for symptom control in neurological disorders, sustainably decreasing the total number of episodes with an acceptable safety profile. There is limited information regarding the use of cannabidiol in neurodegenerative diseases, the reason its effectiveness has not been demonstrated.

Percepções de familiares sobre uma rede de cuidados de saúde mental infantojuvenil / Family perceptions about a children's mental health network / Percepciones familiares sobre una red de atención de salud mental infantojuvenil

Este artigo pretende conhecer como a rede de cuidados em saúde tem se operacionalizado a partir da percepção de familiares de crianças com demanda de cuidado em saúde mental (SM). Foram realizados dois grupos focais, um com familiares da Atenção Básica (AB) e outro com familiares do Centro de Atenção Psicossocial Infantojuvenil (CAPSij), totalizando 15 participantes. Seguiu-se com a análise lexical do tipo classificação hierárquica descendente, com o auxílio do software R Interface, a fim de análises multidimensionais de textos e questionários (IRaMuTeQ), resultando em cinco classes: A Pílula Mágica; Forças e Fraquezas dos serviços; Procurando por ajuda; Aceitando o diagnóstico da criança e Onde procurei ajuda. Os resultados apontam para dificuldades presentes na AB em identificar e manejar situações de Saúde Mental Infantojuvenil (SMIJ), por meio de uma lógica ainda medicalizante. Ressalta-se que a escola é apresentada como lugar de destaque na produção da demanda por cuidado e a família ainda é pouco convocada à construção das ações. Conclui-se, então, que avanços ainda são necessários para operacionalização de um cuidado pautado nas diretrizes da política de SMIJ.(AU)

This article aims to know how the healthcare network has been operationalized from the perception of family members of children with demand for mental health care (MH). Two focus groups were held, one with family members from Primary Care (PC) and the other with family members from the Child Psychosocial Care Center (CAPSij), totaling 15 participants. A lexical analysis of the descending hierarchical classification type was performed with the help of the software R Interface for multidimensional analyzes of texts and questionnaires (IRAMUTEQ), resulting in five classes: The Magic Pill; Strengths and Weaknesses of services; Looking for help; Accepting the child's diagnosis; and Where did I look for help. The results point to difficulties present in PC in identifying and managing situations of mental health in children and adolescents (MHCA), with a medicalization logic. Note that the school is presented as a prominent place in producing the demand for care, and the family is still not very much involved in the actions. It is, thus, concluded that advances are still needed for operationalization of care guided by MHCA policy guidelines.(AU)

Este artículo tuvo por objetivo conocer cómo opera una red asistencial a partir de la percepción de familiares de niños con demanda de atención en salud mental (SM). Se realizaron dos grupos focales, uno con familiares de Atención Primaria (AP) y otro con familiares del Centro de Atención Psicosocial Infantojuvenil (CAPSij), totalizando 15 participantes. Se realizó análisis léxico del tipo clasificación jerárquica descendente con la ayuda del software Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires (IRAMUTEQ), lo que resultó en cinco clases: "La píldora mágica"; "Fortalezas y debilidades de los servicios"; "En busca de ayuda"; "Aceptar el diagnóstico del niño" y "¿Dónde busqué ayuda?". Los resultados apuntan las dificultades presentes en AP para identificar y manejar situaciones de salud mental infantojuvenil (SMIJ) mediante una lógica aún medicalizante. La escuela tiene un lugar destacado en la producción de la demanda de cuidados y la familia aún no está muy involucrada en la construcción de acciones. Se concluye que se necesitan avances para ofertar una atención guiada por lineamientos de la política del SMIJ.(AU)

Pattern and determinants of outcomes of neurological emergencies admitted into children emergency ward in a tertiary hospital in Port Harcourt, Nigeria

Background: Neurological emergencies are life-threatening central nervous system disorders, significantly contributing to childhood morbidity and mortality. The sequelae may be irreversible and may impact negatively on the quality of life of affected children and their families. This study identified the morbidity pattern and determinants of the outcomes of children with neurological emergencies in the Children Emergency Room (CHER) of the Rivers State University Teaching Hospital (RSUTH). Method: A 4-year retrospective study was carried out in the CHER. Data on demography, diagnosis and outcomes of children with neurological disorders were extracted from the records. Data analysed with SPSS 24 were expressed in percentages and frequency tables. Results: Of the 3040 children admitted in the CHER, 364(12%) aged 0-15 years had neurological emergencies, commoner among males (59.3%) and children aged less than five years (70.9%). Meningitis (40.2%) and febrile convulsion (28.2%) were the topmost diagnoses made. Raised intracranial pressure (17.4%) and head injuries (25.5%) were significantly more prevalent among children aged five years and above. The mortality rate was 61(16.8%) and more among adolescents (30.6%). All the mortalities took place within the first 48hours of admission especially among those with head injuries (46.5%) and perinatal asphyxia (95%), (p < 0.05). Conclusion: Meningitis and febrile convulsion were the commonest neurologic emergencies seen in this study. Mortality rate was high, especially in the first 48 hours of admission and mainly from perinatal asphyxia and head injuries. Education on the prevention and management of neurologic emergencies should be strengthened.

Updated Understanding of the Glial-Vascular Unit in Central Nervous System Disorders / 神经科学通报·英文版

The concept of the glial-vascular unit (GVU) was raised recently to emphasize the close associations between brain cells and cerebral vessels, and their coordinated reactions to diverse neurological insults from a "glio-centric" view. GVU is a multicellular structure composed of glial cells, perivascular cells, and perivascular space. Each component is closely linked, collectively forming the GVU. The central roles of glial and perivascular cells and their multi-level interconnections in the GVU under normal conditions and in central nervous system (CNS) disorders have not been elucidated in detail. Here, we comprehensively review the intensive interactions between glial cells and perivascular cells in the niche of perivascular space, which take part in the modulation of cerebral blood flow and angiogenesis, formation of the blood-brain barrier, and clearance of neurotoxic wastes. Next, we discuss dysfunctions of the GVU in various neurological diseases, including ischemic stroke, spinal cord injury, Alzheimer's disease, and major depression disorder. In addition, we highlight the possible therapies targeting the GVU, which may have potential clinical applications.

Gut microbiota: a new insight into neurological diseases / 中华医学杂志(英文版)

In the last decade, it has become increasingly recognized that a balanced gut microbiota plays an important role in maintaining the health of the host. Numerous clinical and preclinical studies have shown that changes in gut microbiota composition are associated with a variety of neurological diseases, e.g., Parkinson's disease, Alzheimer's disease, and myasthenia gravis. However, the underlying molecular mechanisms are complex and remain unclear. Behavioral phenotypes can be transmitted from humans to animals through gut microbiota transplantation, indicating that the gut microbiota may be an important regulator of neurological diseases. However, further research is required to determine whether animal-based findings can be extended to humans and to elucidate the relevant potential mechanisms by which the gut microbiota regulates neurological diseases. Such investigations may aid in the development of new microbiota-based strategies for diagnosis and treatment and improve the clinical management of neurological disorders. In this review, we describe the dysbiosis of gut microbiota and the corresponding mechanisms in common neurological diseases, and discuss the potential roles that the intestinal microbiome may play in the diagnosis and treatment of neurological disorders.

Correlation between four limbs perfusion index and lactic acid in patients with severe neurological diseases / 中华危重病急救医学

OBJECTIVE@#To observe the correlation between the four limbs perfusion index (PI) and blood lactic acid in patients with neurosis, and evaluate the predictive value of PI on microcirculation perfusion metabolic disorder in patients with neurosis.@*METHODS@#A prospective observational study was conducted. Adult patients admitted to the department of neurological intensive care unit (NICU) of the First Affiliated Hospital of Xinjiang Medical University from July 1 to August 20 in 2020 were enrolled. Under the condition of indoor temperature controlled at 25 centigrade, all patients were placed in the supine position, and the blood pressure, heart rate, PI of both fingers and thumb toes and arterial blood lactic acid were measured within 24 hours and 24-48 hours after NICU. The difference of four limbs PI at different time periods and its correlation with lactic acid were compared. Receiver operator characteristic curve (ROC curve) was used to evaluate the predictive value of four limbs PI on patients with microcirculatory perfusion metabolic disorder.@*RESULTS@#A total of 44 patients with neurosis were enrolled, including 28 males and 16 females; average age (61.2±16.5) years old. There were no significant differences in PI of the left index finger and the right index finger [2.57 (1.44, 4.79) vs. 2.70 (1.25, 5.33)], PI of the left toe and the right toe [2.09 (0.85, 4.76) vs. 1.88 (0.74, 4.32)] within 24 hours after entering the NICU, and the PI of the left index finger and the right index finger [3.17 (1.49, 5.07) vs. 3.14 (1.33, 5.36)], PI of the left toe and the right toe [2.07 (0.75, 5.20) vs. 2.07 (0.68, 4.67)] at 24-48 hours after NICU admission (all P > 0.05). However, compared to the PI of the upper and lower limbs on the same side, except for the 24-48 hours after ICU of the PI difference between the left index finger and the left toe (P > 0.05), the PI of the toe was lower than that of the index finger at the other time periods (all P < 0.05). The correlation analysis showed that the PI value of four limbs of patients in both time periods were significantly negatively correlated with arterial blood lactic acid (the r values of the left index finger, the right index finger, the left toe and the right toe were -0.549, -0.482, -0.392 and -0.343 respectively within 24 hours after entering the NICU; the r values of the left index finger, the right index finger, the left toe and the right toe were -0.331, -0.292, -0.402 and -0.442 respectively after entering the NICU 24-48 hours, all P < 0.05). Taking lactic acid ≥ 2 mmol/L as the diagnostic standard for metabolic disorder of microcirculation perfusion (total 27 times, accounting for 30.7%). The efficacy of four limbs PI in predicting microcirculation perfusion metabolic disorder were compared. ROC curve analysis showed that the area under the curve (AUC) and 95% confidence interval (95%CI) of left index finger, right index finger, left toe and right toe predicting microcirculation perfusion metabolic disorder were 0.729 (0.609-0.850), 0.767 (0.662-0.871), 0.722 (0.609-0.835), 0.718 (0.593-0.842), respectively. There was no significant difference in AUC compare with each other (all P > 0.05). The cut-off value of PI of right index finger for predicting microcirculation perfusion metabolic disorder was 2.46, the sensitivity was 70.4%, the specificity was 75.4%, the positive likelihood ratio was 2.86, and the negative likelihood ratio was 0.30.@*CONCLUSIONS@#There are no significant differences in PI of bilateral index fingers, bilateral toes in patients with neurosis. However, unilateral upper and lower limbs showed lower PI in the toe than in the index finger. There is a significantly negatively correlation between PI and arterial blood lactic acid in all four limbs. PI can predict the metabolic disorder of microcirculation perfusion, and its cut-off value is 2.46.

Afasia primaria progresiva y sus variantes: diagnóstico, evolución, características imagenológicas y manejo / Progressive primary aphasia and its variants: diagnosis, evolution, imaging characteristics and management

RESUMEN INTRODUCCIÓN: Las demencias son un conjunto de trastornos neurocognitivos, en personas con edad menor a 65 años sobresale la demencia frontotemporal, síndrome neurodegenerativo heterogéneo que tiene dos grandes variantes: conductual y afasia primaria progresiva. En esta última se describen tres variantes: no fluente, semántica y logopénica, que exigen en la práctica conocimientos actualizados para su diferenciación y comprensión. El objetivo de este escrito es hacer una revisión narrativa sobre las tres variantes clínicas de la afasia primaria progresiva, profundizando en diagnóstico, evolución, características imagenológicas y manejo. MATERIALES Y MÉTODOS: Artículo de revisión narrativa a partir del estado del arte en literatura biomédica sobre demencia frontotemporal, afasia primaria progresiva y sus variantes. RESULTADOS: El compromiso del lenguaje y de otras funciones cognitivas, así como los hallazgos imagenológicos, son heterogéneos en las tres variantes. Semiológicamente, la afasia primaria progresiva no fluente se caracteriza por apraxia del habla, la variante logopénica por fallas en la nominación y la variante semántica por fallas en el significado del mensaje. El compromiso imagenológico en la afasia primaria progresiva no fluente es más frontoinsular y corticosubcortical; en la variante semántica es habitualmente temporal del lado dominante; y en la variante logopénica priman alteraciones temporoparietales. No hay tratamiento específico, pero se puede vincular algunas opciones farmacológicas con procesos/técnicas de rehabilitación del lenguaje. CONCLUSIÓN: Si bien se trata de una forma heterogénea de demencia, tiene características clínicas (síntomas, signos y evolución) e imagenológicas importantes a la hora de su detección y diagnóstico en ambientes clínicos.

ABSTRACT INTRODUCTION: Dementias are a group of neurocognitive disorders, and in people under 65 years of age, frontotemporal dementia stands out, a heterogeneous neurodegenerative syndrome that has two major variants: behavioral and primary progressive aphasia. In the latter, three variants are described: non-fluent, semantic and logopenic, which require up-to-date knowledge in practice for their differentiation and understanding. The objective is to carry out a narrative review on the three clinical variants of primary progressive aphasia, delving into diagnosis, evolution, imaging characteristics and management. MATERIALS AND METHODS: Narrative review article based on the state of the art in biomedical literature on frontotemporal dementia, primary progressive aphasia and its variants. RESULTS: The compromise of language and other cognitive functions, as well as the imaging findings, are heterogeneous in the three variants. Semiologically, non-fluent progressive primary aphasia is characterized by apraxia of speech, the logopenic variant by failures in the nomination and the semantic variant by failures in the meaning of the message. Imaging involvement in non-fluent progressive primary aphasia is mainly frontoinsular and cortico-subcortical; in the semantic variant it is usually temporary on the dominant side; and in the logopenic variant, temporo-parietal alterations prevail. There is no specific treatment, but some pharmacological options can be linked with language rehabilitation processes / techniques. CONCLUSION: although Frontotemporal dementia is an heterogenous disorder, there are important clinical and imagenologic features that are useful to the diagnostic approach in the clinical field.

Introdução: Devido à COVID-19, os pacientes com doenças neurológicas deixaram de frequentar presencialmente as consultas fonoaudiológicas em ambulatórios. Objetivo: Descrever o relato da experiência fonoaudiológica em pacientes com doença neurológica com disartria e/ou disfagia durante a pandemia da COVID-19 através da telessaúde. Método: Trata-se de um relato de experiência. Foram incluídos pacientes do ambulatório de fonoaudiologia de um hospital universitário, que ficaram privados do acompanhamento fonoaudiológico em período pandêmico e que tinham diagnóstico de disfagia e/ou disartria (prévios à pandemia). No total, 43 pacientes foram convidados a participar do estudo. Os indivíduos foram separados de acordo com seu diagnóstico fonoaudiológico: disfagia, disartria e disfagia/disartria. No início, todos foram reavaliados em videochamadas: disfagia (Northwestern dysphagia patient check sheet, Escala Funcional de Ingestão Via Oral e Instrumento de Autoavaliação da Alimentação); disartria (coleta de fala e questionário de autopercepção Radbould Oral Inventory Motor for Parkinson's disease). Após, os pacientes foram alocados aleatoriamente: teleatendimento fonoaudiológico por quatro semanas consecutivas, sendo o outro grupo controle, sem intervenções e/ou orientações. Todos foram reavaliados para a comparação pré e pós-acompanhamento fonoaudiológico. Resultados: Nove participantes concluíram todas as etapas do estudo, sendo 6 (66,66%) homens. A média de idade foi de 60,44 anos (±16,13). Os participantes possuíam diagnóstico médico de doença neurológica, sendo 2 neurogenética (22,22%), 5 neurodegenerativa (55,5%) e 2 neurológicas (22,22%). Não foram observadas diferenças descritivas entre os grupos nas avaliações pré e pós-intervenção. A perda na amostra aconteceu devido à falta de dispositivos tecnológicos e à sobrecarga dos cuidadores. Conclusões: A experiência em tele fonoaudiologia, apesar de ter sido positiva, revelou a dificuldade da sua implementação em pacientes neurológicos de baixa condições sócio financeiras e educacional.

Introduction: Due to COVID-19, patients with neurological disease no longer attend face-to-face speech therapy consultations in outpatient clinics. Objective: To describe the report of the speech therapy experience patients with neurological disease with dysarthria and/or dysphagia during the COVID-19 pandemic through telehealth. Method: This is an experience report. Patients from the speech therapy outpatient clinic of a university hospital who were deprived of speech therapy during a pandemic period and had a diagnosis of dysphagia and/or dysarthria (prior to the pandemic) were included. In total, 43 patients were invited to participate in the study. Individuals were separated according to their speech-language diagnosis: dysphagia, dysarthria, and dysphagia/dysarthria. In the beginning, all were reassessed in video calls: dysphagia (Northwestern dysphagia patient check sheet, Functional Oral Intake Scale, and Food Self-Assessment Instrument); dysarthria (speech collection and self-perception questionnaire Radbould Oral Motor Inventory for Parkinson's disease). Afterward, the patients were randomly allocated: speech therapy telecare for four consecutive weeks, with the other being a control group, without interventions and/or guidance. All were reassessed for comparison before and after speech therapy follow-up. Results:Nine participants completed all stages of the study, 6 (66.66%) men. The mean age was 60.44 years (±16.13). Participants had a medical diagnosis of neurological disease, 2 of which were neurogenetic (22.22%), five neurodegenerative (55.5%), and two neurologic (22.22%). No descriptive differences were observed between groups in pre- and post-intervention assessments. The loss in the sample happened due to the lack of technological devices and the overload of caregivers. Conclusions: The experience in telehealth was positive, revealing the difficulty of its implementation in neurological patients with low socio-financial and educational conditions.

Introducción: Debido al COVID-19, los pacientes con enfermedades neurologicas ya no asisten a consultas de logopedia presenciales en consultas externas. Objetivo: Describir el relato de la experiencia fonoaudiológica en pacientes con enfermedades neurologicas con disartria y/o disfagia durante la pandemia de COVID-19 a través de telesalud. Método: Este es un relato de experiencia. Se incluyeron pacientes de la consulta externa de logopedia de un hospital universitario, que fueron privados de logopedia durante un período de pandemia y que tenían diagnóstico de disfagia y/o disartria (previo a la pandemia). En total, 43 pacientes fueron invitados a participar en el estudio. Los individuos se separaron según su diagnóstico del habla y el lenguaje: disfagia, disartria y disfagia/disartria. Al principio, todos fueron reevaluados en videollamadas: disfagia (Northwestern dysphagia patient check sheet), Escala de ingesta oral funcional e Instrumento de autoevaluación de alimentos); disartria (cuestionario de recogida de voz y autopercepción Radbould Oral Motor Inventory for Parkinson's disease). Posteriormente, los pacientes fueron asignados aleatoriamente: teleasistencia logopédica durante cuatro semanas consecutivas, siendo el otro grupo control, sin intervenciones y/u orientaciones. Todos fueron reevaluados para compararlos antes y después del seguimiento con logopedia. Resultados: Nueve participantes completaron todas las etapas del estudio, 6 (66,66%) hombres. La edad media fue de 60,44 años (±16,13). Los participantes tenían diagnóstico médico de enfermedad neurológica, 2 de ellas neurogenéticas (22,22%), 5 neurodegenerativas (55,5%) y 2 neurológica (22,22%). No se observaron diferencias descriptivas entre los grupos en las evaluaciones previas y posteriores a la intervención. La pérdida en la muestra ocurrió por la falta de dispositivos tecnológicos y la sobrecarga de cuidadores. Conclusiones: La experiencia en telefonoaudiología, a pesar de ser positiva, reveló la dificultad de su implementación en pacientes neurológicos de baja condición socioeconómica y educativa.

Cognitive Alterations in Elderly Patients with Heart Failure'

Abstract Background: Among the various pathologies that affect the elderly, Heart Failure (HF) stands out. Recently, an attempt has been made to verify the existence of cognitive impairment associated with HF. Objectives: To compare the cognitive performance of elderly people with heart failure with that of age-matched individuals without this pathology. Check the existence of marked impairment in some cognitive functions in the clinical group. Methods: The sample consisted of 78 elderly people, whose inclusion criterion was the presence of HF and no HF (control group); age over 60 years, both sexes, and any level of education. The control group consisted of 37 individuals (with a median age of 68 years - Interquartile range of 12) and the HF group, with 41 individuals (with a median age of 67 years - Interquartile range of 11). The subjects were matched in terms of education level, with a predominance of elderly people with 0 to 4 years of education (65.9% in the Clinical Group and 59.5% in the Control Group). Eleven neuropsychological tests covering cognitive functions were used: attention, language, memory, mood, and executive function. Statistical analysis was performed using SPSS software, version 23, with a significance level of 5%. The Chi-square test and the Mann-Whitney test were applied. Results: The results showed significant differences between the groups, mainly in executive functions, which include the ability to plan, switch, and recall previously stored information. Conclusion: Our study showed differences between the cognitive performance of elderly people with HF and elderly people without HF. The main alteration was found in the so-called executive functions, attention, and memory.

Pattern of neurological disorders managed in neurology clinics in Kano, Nigeria

To determine the pattern of neurological disorders managed in some neurology clinics in Kano, Nigeria. Materials and Methods: A five-year retrospective descriptive survey (2016-2020) of patients with neurological disorders attending neurology out-patient clinics at three selected hospitals in Kano metropolis. A research proforma was used to collect information on socio-demographic and health characteristics of the participants. Case folders and outpatient registers were used as a source of information about the patients. Data obtained was analyzed using IBM Statistical package for social science (SPSS) version 20 and results presented using descriptive statistics of frequency and percentage. Results: Out of the 433 cases with neurological disorders surveyed, 58% were adult and 42% were pediatric. Males (54.3%) were found to be more affected. Majority (83.4%) of the participants were from an urban area, with married (79.7%) individuals mostly affected. Stroke was the most prevalent (33.7%) neurological disorder. Hypokinesia (5.1%) and hyperkinesia(3%) as a primary and secondary movement disorder respectively were the most prevalent forms of movement disorder. Psychotic symptoms, weakness, paresthesia, fever, vomiting and convulsion were the most common manifestations that comes with the neurological disorders. Of the common neurological disorders, stroke was most associated with motor (56.2%), sensory (36.4%) and psychiatric (43.5%) manifestations. Conclusion: Paediatric age group contributed close to half of neurological disorders. Stroke was the most prevalent form of neurological disorder and most associated with motor, sensory and psychiatric manifestations. Hypokinesia and hyperkinesia had close prevalence and were the most common primary and secondary movement disorders respectively.

The p21-activated kinases in neural cytoskeletal remodeling and related neurological disorders

The serine/threonine p21-activated kinases (PAKs), as main effectors of the Rho GTPases Cdc42 and Rac, represent a group of important molecular switches linking the complex cytoskeletal networks to broad neural activity. PAKs show wide expression in the brain, but they differ in specific cell types, brain regions, and developmental stages. PAKs play an essential and differential role in controlling neural cytoskeletal remodeling and are related to the development and fate of neurons as well as the structural and functional plasticity of dendritic spines. PAK-mediated actin signaling and interacting functional networks represent a common pathway frequently affected in multiple neurodevelopmental and neurodegenerative disorders. Considering specific small-molecule agonists and inhibitors for PAKs have been developed in cancer treatment, comprehensive knowledge about the role of PAKs in neural cytoskeletal remodeling will promote our understanding of the complex mechanisms underlying neurological diseases, which may also represent potential therapeutic targets of these diseases.

Epigenetic regulation of microglia-mediated innate immune memory and neurological diseases / 生理学报

Microglia have the ability to mediate innate immune memory and can be reprogrammed by primary stimuli to enhance or inhibit the immune response of microglia to secondary stimuli. Inflammatory stimulation is an important factor for microglia to mediate innate immune memory. Single or repeated stimulation can induce microglia to form different phenotypes. Microglia-mediated innate immune response is involved in the regulation of immune memory. Enhancer modification is a key pathway of microglia epigenetic regulation, and the H3K27ac enhancer marker is closely related to immune training. TGF-β1 mediates the interaction between IL-10 and IL-1β, thereby influencing the microglial phenotype. Microglia glycolysis activity is increased after immune training, and oxidative phosphorylation is associated with immune tolerance. Innate immune memory is closely associated with neurodegenerative diseases, brain tumors, brain damage and psychosis. Further study on the mechanism of microglia-mediated innate immune memory is helpful to understand the occurrence and development of central nervous system diseases and provide new options for the treatment of central nervous system diseases.
