RESUMO

Limited evidence suggests that the SARS-CoV-2 infection can accelerate the progression of neurodegenerative diseases, but this has been not verified in the spinocerebellar ataxias (SCA). The objective of this study is to assess the impact of COVID-19 on the mental health and motor features of SCA2. A follow-up study was carried out in 170 Cuban SCA2 subjects and 87 community controls between 2020 and 2021. All subjects underwent a structured questionnaire to assess the risks of exposure to COVID-19, the confirmation of COVID-19 diagnosis, and the Hospital Anxiety and Depression Scale (HADS). Moreover, 36 subjects underwent the Scale for the Assessment and Rating of ataxia (SARA). The risk of exposure to SARS-CoV-2 and the frequency of COVID-19 were similar between the ataxia cohort and the community controls. Within the ataxia group, significantly increased HADS scores existed at the 2nd visit in both groups, but this increase was more evident for the infected group regarding the depression score. Moreover, a significant within-group increase of SARA score was observed in the infected group but not the non-infected group, which was mainly mediated by the significant increase of the speech item score in the infected group. Similar results were observed within the subgroup of preclinical carriers. Our study identified no selective vulnerability nor protection to COVID-19 in SCA2, but once infected, the patients experienced a deterioration of mental health and speech function, even at preclinical disease stage. These findings set rationales for tele-health approaches that minimize the detrimental effect of COVID-19 on SCA2 progression and identify SCA2 individuals as clinical model to elucidate the link between SARS-CoV-2 infection and neurodegeneration.

RESUMO

Introducción: Las tendencias seglares influyen en el crecimiento y desarrollo general del individuo. El brote dentario no escapa a esta realidad. Existen variables que pueden retardarlo o acelerarlo, dentro de las que se encuentran el sexo y el color de la piel. Objetivos: Determinar la cronología y el orden de brote de los dientes permanentes en niños y adolescentes. Métodos: Se realizó un estudio transversal descriptivo desde mayo de 2017 a noviembre de 2020. El universo constituido por 21383 niños y adolescentes entre 5 y 13 años de edad, de la provincia Holguín, Cuba, que no presentaban pérdida prematura de dientes temporales o extracciones de dientes permanentes, ni enfermedades sistémicas que influyen en el crecimiento y desarrollo. En el procesamiento estadístico se utilizaron las medidas de resúmenes para las variables cuantitativas y el test de comparación de las medias. Resultados: La edad de brote de todos los dientes permanentes resultó adelantada en comparación con las tablas para su valoración clínica. El primer diente en brotar fue el primer molar superior, entre los 5,66 años, y el último el segundo molar maxilar, entre los 10,38 años. Al comparar las medias de brote de los dientes permanentes según el sexo, hubo diferencias altamente significativas en la arcada superior: primer premolar (p = 0,000), arcada inferior: canino (p = 0,009), primer premolar (p = 0,000) y segundo molar (p = 0,012). Se encontraron diferencias altamente significativas entre las medias de brote para el color de la piel en el maxilar: incisivo central (p = 0,004), incisivo lateral (p = 0,000), canino (p = 0,002), mandíbula: incisivo central (p = 0,000), incisivo lateral (p = 0,000) y segundo premolar (p = 0,000). Conclusiones: La cronología de brote de todos los dientes permanentes resultó adelantada. Los dientes permanentes siguieron la secuencia de brote, tal como describe Mayoral. Se encontraron diferencias al comparar las medias de brote según el sexo y color de la piel(AU)

Introduction: Secular tendencies influence the overall growth and development of the individual. Tooth eruption does not escape this reality. There are variables that can delay or accelerate it, among which are sex and skin color. Objectives: To determine the chronology and order of eruption of permanent teeth in children and adolescents. Methods: A descriptive cross-sectional study was conducted from May 2017 to November 2020. The universe constituted by 21383 children and adolescents between 5 and 13 years of age, from Holguín province, Cuba, who did not present premature loss of primary teeth or extractions of permanent teeth, nor systemic diseases that influence growth and development. Statistical processing used summary measures for quantitative variables and the comparison test of the average values. Results: The age of teething of all permanent teeth was advanced in comparison with the tables for clinical assessment. The first tooth was the upper first molar at 5.66 years of age and the last tooth was the maxillary second molar at 10.38 years of age. When comparing the teething averages of the permanent teeth according to gender, there were highly significant differences in the upper arch: first premolar (p = 0.000), lower arch: canine (p = 0.009), first premolar (p = 0.000) and second molar (p = 0.012). Highly significant differences were found between bud means for skin color in maxilla: central incisor (p = 0.004), lateral incisor (p = 0.000), canine (p = 0.002), mandible: central incisor (p = 0.000), lateral incisor (p = 0.000) and second premolar (p = 0.000). Conclusions: The teething chronology of all permanent teeth resulted advanced. The permanent teeth followed the teething sequence as described by Mayoral. Differences were found when comparing the teething averages according to gender and skin color(AU)

RESUMO

El objetivo del estudio fue caracterizar el potencial investigador cubano en el ámbito de las ataxias y su evolución temporal. Se realizó una búsqueda en la base de datos Web of Science y se obtuvieron todos los documentos publicados entre 1993 y 2020. Se aplicaron indicadores bibliométricos para explorar la producción, dispersión, distribución y crecimiento anual de los documentos (ley de Price, ley de Lotka, índice de transitoriedad y modelo de Bradford). Se calculó el índice de participación y colaboración de países e instituciones y, por cartografía bibliométrica, se exploraron las redes de coocurrencia de los términos más utilizados. La producción científica de Cuba sobre ataxias hereditarias es alta (219 documentos) y se ajusta a un crecimiento lineal (r= 0,7580). El período estudiado concentra el 47,95 por ciento de los registros con un ritmo anual de publicaciones del 6,6 por ciento y tiempo de duplicidad de 10,8 años. El total de citas fue de 3807 (índice medio: 131,27; índice -h: 31). Se concluye que el crecimiento de la literatura científica cubana sobre ataxias fue lineal para el período estudiado, lo que confirma el incumplimiento de la ley de Price de crecimiento de la literatura científica. El estudio también corrobora la importante red de integración y cooperación internacional entre los diferentes autores y la interdisciplinariedad de los trabajos, evidencia del éxito del Centro para la Investigación y Rehabilitación de las Ataxias Hereditarias (CIRAH), al planificar una estrategia de colaboración científica con objetivos definidos(AU)

The objective of this study was to characterize the Cuban research potential in the field of ataxias and its temporal evolution. A search was carried out in the Web of Science database and all the documents published from 1993 to 2020 were retrieved. Bibliometric indicators were applied to explore the production, dispersion, distribution and annual growth of the documents (Price's law, Lotka's law, transience index and Bradford model). The participation and collaboration index of countries and institutions was calculated and, through bibliometric cartography, the co-occurrence networks of the most used terms were explored. The Cuban scientific production on hereditary ataxias is high (219 documents) and it adjusts to a linear growth (r = 0.7580). The period studied concentrates 47.95percent of the records with an annual publication rate of 6.6percent and 10.8 years' duplication time. The total number of citations was 3807 (mean index: 131.27; h-index: 31). Growth of the Cuban scientific literature on ataxias was concluded to be linear for the period studied, which confirms the non-compliance with Price's law of growth of scientific literature. The study also corroborates the important network of integration and international cooperation among the different authors and the interdisciplinarity of the papers, marking the success of the Center for Research and Rehabilitation of Hereditary Ataxias (CIRAH), when planning a strategy of scientific collaboration with objectives defined(AU)

ABSTRACT Introduction: A biokinematic analysis of gait was performed in patients with hemiplegia, which is the paralysis of one side of the body, recognized in the context of medical sciences and therapeutic physical culture as hemiplegic syndrome. Objective: It consisted of determining the biokinematic modifications that are manifested in the gait of patients with hemiplegia in the "Pedro Díaz Coello" health area of Holguín. Materials and methods: The sample consisted of five patients who received systematic care in the rehabilitation room of the health area of the " Pedro Díaz Coello" polyclinic in the municipality of Holguín. The interviews conducted with medical and physical rehabilitation personnel who work in the health area, with researchers from the Faculty of Physical Culture and Sports of the University of Holguín, the review of normative documents on multidisciplinary work and the observation of rehabilitation sessions, showed the need to address the issue from biomechanics, given the limited quantification of its indicators. In order to analyze the behavior of biokinematic indicators of pathological gait, the videographic technique was used. With the Kinovea software, in version 0.8.27, the controlled indicators were quantified. Results: Together with the qualitative study for each patient, it allowed a comparison of the characteristics of their gait with the normal pattern and the elaboration of a group of recommendations to be considered during the physical rehabilitation process. Conclusions: It was possible to analyze the behavior of the biokinematic indicators of hemiplegic gait in the patients studied, their comparison with normal gait, as well as a set of recommendations to be taken into account in the rehabilitation process

RESUMO

BACKGROUND: Several pieces of evidence have shown the neurotrophic effect of erythropoietin (EPO) and its introduction in the therapeutic practice of neurological diseases. However, its usefulness in the treatment of spinocerebellar ataxia type 2 (SCA2) has not been proven despite the fact that it is endogenously reduced in these patients. OBJECTIVE: The study aims to investigate the safety, tolerability, and clinical effects of a nasally administered recombinant EPO in SCA2 patients. METHODS: Thirty-four patients were enrolled in this double-blind, randomized, placebo-controlled, phase I-II clinical trial of the nasally administered human-recombinant EPO (NeuroEPO) for 6 months. The primary outcome was the change in the spinocerebellar ataxia functional index (SCAFI), while other motor, neuropsychological, and oculomotor measures were assessed. RESULTS: The 6-month changes in SCAFI score were slightly higher in the patients allocated to NeuroEPO treatment than placebo in spite of the important placebo effect observed for this parameter. However, saccade latency was significantly decreased in the NeuroEPO group but not in placebo. The frequency and severity of adverse events were similar between both groups, without evidences of hematopoietic activity of the drug. CONCLUSIONS: This study demonstrated the safety and tolerability of NeuroEPO in SCA2 patients after 6 months of treatments and suggested a small clinical effect of this drug on motor and cognitive abnormalities, but confirmatory studies are warranted. © 2022 International Parkinson and Movement Disorder Society.

RESUMO

BACKGROUND: Body weight changes occur frequently during advanced stages of Spinocerebellar Ataxia type 2 (SCA2), nevertheless limited information exists on biomarkers of nutritional status of these patients. OBJECTIVE.: To assess changes in surrogate nutritional markers of SCA2 patients; to explore their associations with expanded CAG repeats and disease severity. METHODS: One-hundred-thirteen SCA2 patients and 50 healthy controls underwent a comprehensive anthropometrical and biochemical assessment protocol of the nutritional status. Neurological and genotype assessments were also performed. RESULTS: A decrease in weight, body mass index (BMI), cutaneous skinfold thickness, fat mass, arm muscle circumference, calf circumference and skeletal muscle mass was observed in SCA2 patients compared to the controls. The total/HDL cholesterol ratio was significantly reduced in patients. BMI was correlated with the age at onset. Overall, anthropometric measures were correlated with clinical markers of disease severity and were more evident in severe and moderate cases. CONCLUSIONS: Using anthropometric measures in the assessment of the nutritional status of SCA2 patients might provide hints about pathophysiological mechanisms that underlie metabolic abnormalities in SCA2. Anthropometric are close related with disease severity and progression, and trigger preventive therapies aimed to ameliorate weight loss and wasting in these patients.

RESUMO

Although there are no convincing evidences of detrimental effect of SARS-CoV2 infection on the cerebellum, the COVID-19 pandemic could impact the life quality of patients with cerebellar ataxias, but few studies have addressed this concern. To assess the motor and mental health changes caused by the COVID-19 pandemics in Cuban patients with cerebellar ataxias, three hundred four patients with cerebellar ataxias and 167 healthy controls were interviewed for risks of exposure to COVID-19, and the self-perception of the pandemics' impact on the disease progression and on the mental health. All subjects underwent the Hospital Anxiety and Depression Scale. The patients reported low exposition to SARS-CoV2 infection, but one case was confirmed with a mild COVID-19. Overall, depressive and anxiety symptoms were significantly and marginally increased in patients, respectively, with higher scores in cases with severe and moderate ataxia. Positive patient's impression of psychopathological changes was associated to increased age, age at onset, and anxiety. Sixty-seven patients had a positive self-perception of ataxia progression, which was mainly influenced by higher anxiety scores but not by the adherence to at-home exercise programs. However, the practice of physical exercise was related with lower depression and anxiety scores, but this therapeutical effect was not significantly influenced by the disease stage. We demonstrated the negative effect of the COVID-19 pandemic on the mental and motor deficits in Cuban patients with cerebellar ataxias and the positive effect of the at-home physical exercise programs on their mental well-being. These findings give rationales to develop tele-medicine approaches to minimize these health impacts and to study the long-term effects of such sequelae and accordingly define their treatments.

RESUMO

BACKGROUND: The search for valid preclinical biomarkers of cerebellar dysfunction is a key research goal for the upcoming era of early interventional approaches in spinocerebellar ataxias. This study aims to describe novel preclinical biomarkers of subtle gait and postural sway abnormalities in prodromal spinocerebellar ataxia type 2 (pre-SCA2). METHODS: Thirty pre-SCA2 patients and their matched healthy controls underwent quantitative assessments of gait and postural sway using a wearable sensor-based system and semiquantitative evaluation of cerebellar features by SARA (Scale for the Assessment and Rating of Ataxia) score. RESULTS: Quantitative analysis of natural gait showed a significantly larger variability of the swing period, toe-off angle and toe-out angle in pre-SCA2, and larger mean coronal and transverse ranges of motion of the trunk at the lumbar location and of the sagittal range of motion of the trunk at the sternum location compared to controls. During tandem gait, pre-SCA2 subjects showed larger lumbar, trunk, and arm ranges of motion than controls. Postural sway analysis showed excessive body oscillation that was increased in tandem stance. Overall, these abnormalities were detected in pre-SCA2 patients without clinical evidence of abnormalities in SARA. The toe-off angle and swing time variability were significantly correlated with the time to ataxia onset, whereas the toe-off angle and transverse range of motion at trunk position during tandem gait were significantly associated with the SARA score. CONCLUSIONS: This study demonstrates early alteration of gait and postural sway control in prodromal SCA2 using a wearable sensor-based system. This offers new pathophysiological hints into this early disease stage and provides novel potential biomarkers for future clinical trials. © 2020 International Parkinson and Movement Disorder Society.
