Palabras clave:Ictus. Mini Nutritional Assessment. Malnutrición. Dependencia. ResumenObjetivo: valorar el estado nutricional (EN) del paciente a los tres meses de sufrir un ictus y establecer la relación del EN con la recuperación funcional y las complicaciones en este periodo. Material y métodos: estudio observacional y transversal que evaluó el EN de pacientes mayores de 65 años a los tres meses de presentar un ictus. El EN se valoró mediante el Mini Nutritional Assessment (MNA). Se recogieron datos sociodemográficos, antropométricos, factores de riesgo cardiovascular, así como el estado funcional (mediante el índice de Barthel y la escala de Rankin modificada) y las complicaciones presentadas. Resultados: incluimos 103 pacientes, con edad media de 75,81 (± 6,73) años. La puntuación en el MNA fue de 23,13 puntos (± 4,47); el 8,2% presentaba malnutrición y el 38,1%, riesgo de malnutrición. No se observaron diferencias en el EN entre mujeres y hombres (p = 0,076) ni relación del EN con la edad. El estado nutricional deficitario se asoció a peor situación funcional (r = 0,608; p < 0,001), al desarrollo de complicaciones (infección urinaria y fiebre) (p = 0,044) y a la disfagia (p = 0,014). Además, aquellos pacientes con mejor EN presentaban mejor calidad de vida (r = 0,506; p < 0,001). También se relacionó con peor nivel socioeconómico (p = 0,020) y mayor institucionalización en centros sociosanitarios (p = 0,004). Conclusiones: el riesgo de desnutrición a corto plazo es frecuente en los supervivientes a un ictus. Este EN se asocia con una peor situación funcional y calidad de vida autopercibida y mayor tasa de complicaciones. Es fundamental detectar precozmente el riesgo de desnutrición en pacientes que han sufrido un ictus. Key words:Stroke. Mini Nutritional Assessment. Malnutrition. Disability. AbstractObjective: To assess the nutritional status (NS) of patients at three months of suffering a stroke, and to establish the relationship between functional recovery and complications in this period. Material and methods: A cross-sectional observational study evaluating the NS of patients older than 65 years at three months of having a stroke. The NS was assessed using the Mini Nutritional Assessment (MNA). Sociodemographic and anthropometric data, cardiovascular risk factors, as well as functional status (through the Barthel index and the modified Rankin scale) and the presented complications were collected. Results: One hundred and three patients were included, with a medium age of 75.81 (± 6.73). The MNA score was 23.13 points (± 4.47); 8.2% had malnutrition and 38.1% had risk of malnutrition. There were no differences in the NS between women and men (p = 0.076) neither relation of the NS with age. NS deficiency was associated with poorer function (r = 0.608; p < 0.001), the development of complications (urinary tract infection and fever) (p = 0.044) and dysphagia (p = 0.014). In addition, those patients with better nutritional status had a better quality of life (r = 0.506; p < 0.001). It was also associated wit...

Introduction: Malnutrition has been associated with a worse outcome in stroke. Its frequency is not well established and sometimes the impact is not considered. Objective: To explore gender differences on nutritional status (NS) after acute stroke and its impact on stroke outcome at 90 days. Methods: We evaluated consecutive acute stroke patients admitted to the Stroke Unit. We analyzed baseline demographics, vascular risk factors, analytic and anthropometric parameters, and stroke characteristics. We determined NS at baseline and 90 days by Mini Nutritional Assessment (MNA) scale to detect patients at malnutrition risk (MR). We divided groups by gender. Chi square test was applied for qualitative variables and T student for quantitative. A probability value of <0.05 was considered significant for all tests. Results: We included 95 patients, 45 women (47,4%). Differences were found comparing women vs men and age (77,9 ± 1,02 vs 75,1 ± 0,9), alcohol consumption (6,7% vs 60%), smoking (4,4% vs 26%) and body mass index (30,1 ± 5,1 vs 27,3 ± 4,5); p<0.05. There were no significant differences related to gender and stroke type (ischemic 88,9% vs 84%, p=0.49) nor stroke severity at baseline (NIHSS 5±4 vs 4±4 p=0.18), neither in risk factors (hypertension, diabetes, atrial fibrillation, dislipidemia), comorbidities nor socioeconomic differences. There were no gender differences in the occurrence of in-hospital complications (27,3% vs 16,3%; p=0,2), dysphagia (6,7% vs 6,0%; p=0.89) nor in NIHSS scoring at discharge (3±3 vs 2±3; p=0.08). On admission, MR was present in 28,5% of the patients. There were no differences between gender and DR (31,1% vs 26%; p=0.58). At 90 days, MR increased to 46,4%. We found significant gender differences (57,8% vs 32%; p=0.024). In the adjusted analysis, female gender was associated with a worst NS at 90days [OR 3,56 (1,1-11,5)]. Modified Rankin scale (mRs) score at 90 days was <=2 in 77,8% of women and 82% of men, p=0.607. MNA score at 90 days was independently associated with a better outcome (mRs<=2) at 90 days adjusted by gender OR 0,13 (0,14-0,46). Conclusion: In our series, female gender was independently related to worse nutritional status at 90 days after the stroke.
