RESUMO. A obesidade sarcopênica (SO), coocorrência de sarcopenia e obesidade, está associada à perda funcional, à fragilidade e à incapacidade em idosos. Recentemente, verificou-se que a SO está associada ao desempenho cognitivo reduzido em adultos. No entanto, não foram feitos estudos de SO em idosos com doença de Alzheimer (AD). Objetivo: Verificar a ocorrência de obesidade sarcopênica e fatores associados em 43 adultos idosos com doença de Alzheimer. Métodos: Aplicamos o miniexame do estado mental (MEEM) e a avaliação clínica da demência (CDR). A SO foi verificada utilizando a absorciometria de dupla emissão de raios X. Resultados: Foram classificadas cinco idosas com SO. As mulheres idosas tinham maior gordura corporal e menor massa muscular em comparação com os homens. Houve relação significativa, ajustada por idade e educação, entre gordura corporal e desempenho cognitivo apenas nos homens (r=0,65; p<0,01). Os homens com obesidade e com mais de 75 anos tiveram melhor desempenho cognitivo em comparação com os homens não obesos <75 anos (p=0,010) e com as mulheres com obesidade >75 anos (p=0,033). Conclusões: As mulheres com AD tinham maior gordura corporal e menor massa muscular do que os homens. A SO ocorreu em mulheres mais velhas com AD. Os homens com maior gordura corporal apresentaram melhor desempenho cognitivo, independentemente da idade e da educação.

ABSTRACT. Sarcopenic obesity (SO), the co-occurrence of sarcopenia and obesity, is associated with functional loss, frailty, and incapacity in older adults. Recently, SO was associated with reduced cognitive performance in adults. However, no SO studies have been done with older adults with Alzheimer’s disease (AD). Objective: The objective of this study was to verify the occurrence of SO and associated factors in 43 older adults with AD. Methods: We applied the Mini-Mental State Examination (MMSE) and Clinical Dementia Rating (CDR). SO was verified by using dual-emission X-ray absorptiometry. Results: We found five women with SO. Women had higher body fat and lower muscle mass compared with men. There was a significant relationship between body fat and cognitive performance only in men (r=0.65; p<0.01) adjusted by age and education. Men with obesity and aged >75 years had better cognitive performance compared with non-obese men aged <75 years (p=0.010) and women with obesity aged >75 years (p=0.033). Conclusions: Women with AD had higher body fat and lower muscle mass than men. SO occurs in older women with AD. Men with higher body fat showed better cognitive performance, independent of age and education.

Abstract Background and aims: home enteral nutrition (HEN) is an established treatment for clinically stable patients. The objective of this study was to determine the frequency and the situation of patients in HEN, in the capital city in the south of Brazil. Methods: in this retrospective study, we recorded all new cases of HEN in adults in Curitiba, Brazil, from January 2006 to December 2015. Data were collected by a dietitian from medical records of patients attending public health settings. The following data were analyzed: clinical diagnosis, diet prescribed during hospitalization and at discharge, and feeding access types. Kaplan-Meier and Cox regression analyses were used to calculate survival. Results: a total of 1,231 patients were included. There was a 425% increase in the frequency of HEN over the years studied. The mean age was 66.7 years, and 54.4% were men. Neurological diseases were the most prevalent (46.4%), followed by cancer (33.6%). Eight hundred and one patients (65.1%) died during this period. Mean HEN duration was 180 days (95% CI 163.6-193.4), with a significant difference between neurological diseases (median: 180 days) and cancer (median: 210 days) (p < 0.05). Neurological disease was an independent risk factor for mortality in patients on HEN (HR: 1.17; CI: 1.08-1.27). Conclusions: the study shows an increase in HEN. Neurological diseases prevailed and presented a risk of mortality, and more than half of the patients with NED died in this period.

Resumen Introducción y objetivos: la nutrición enteral domiciliaria (NED) es un tratamiento establecido para pacientes clínicamente estables. El objetivo de este estudio fue determinar la frecuencia y la situación de los pacientes con NED en la capital del sur de Brasil. Métodos: en este estudio retrospectivo se registraron todos los nuevos casos de NED en adultos en Curitiba, Brasil, de enero de 2006 a diciembre de 2015. Los datos fueron recolectados por un nutricionista de historiales clínicos de pacientes que frecuentan establecimientos de salud pública. Se analizaron los siguientes datos: diagnóstico clínico, dieta prescrita durante la estancia hospitalaria y en el momento del alta y acceso alimenticio. Se utilizaron los análisis de Kaplan-Meier y regresión de Cox para calcular la supervivencia. Resultados: fueron incluidos 1.231 pacientes. Hubo un aumento del 425% en la frecuencia de NED a lo largo de los años estudiados. La edad media fue de 66,7 años y el 54,4% eran hombres. Las enfermedades neurológicas fueron las más prevalentes (46,4%), seguidas de las neoplasias (33,6%). Durante este periodo murieron 801 pacientes (65,1%). La duración media de la NED fue de 180 días (IC 95%, 163,6-193,4), con una diferencia significativa entre enfermedades neurológicas (mediana: 180 días) y cáncer (mediana: 210 días) (p < 0,05). La enfermedad neurológica fue un factor de riesgo independiente para la mortalidad en pacientes en NED (HR: 1,17; IC: 1,08-1,27). Conclusiones: el estudio muestra un aumento en la NED. Las enfermedades neurológicas prevalecieron y presentaron riesgo de mortalidad y más de la mitad de los pacientes murieron durante la NED.
