ABSTRACT
BACKGROUND: Oropharyngeal dysphagia (OD) is common among older adults. Some studies have evaluated the efficacy of a texture-modified diet on mortality but with short-term follow-up. We aimed to evaluate the effect of a texture-modified diet and controlled bolus volume on all-cause mortality after 12 months in older persons with OD. METHODS: This secondary analysis of a randomized clinical trial included patients aged ≥60 years with a diagnosis of OD. They were concurrently and randomly assigned to receive either a texture-modified food diet and controlled bolus volume (intervention group) or standard treatment (control group) with 12 months of follow-up. Secondary outcomes were oral intake, weight, handgrip strength, phase angle, and aspiration pneumonia. Kaplan-Meier analysis and the Cox proportional hazards model were used for mortality analysis. RESULTS: A total of 127 participants (intervention group: 64 and control group: 63) were recruited, with a mean age of 76 years. The probability of all-cause mortality was significantly lower in the intervention group (n = 8, 12%) than in the control group (n = 18, 29%) (hazard ratio = 0.36 [95% CI = 0.16-0.86]; P = 0.01). There were 5 (7.9%) and 10 (16.1%) aspiration pneumonia events in the intervention and control groups, respectively (not significant) in 12 months of follow-up. Changes were observed in protein consumption (P = 0.01), body weight (P = 0.04), body mass index (P = 0.004), handgrip strength (P = 0.02), and phase angle (P = 0.04) between the treatment groups. CONCLUSION: Compared with the standard treatment, the dietary intervention improved efficacy by limiting nutrition complications, aspiration pneumonia, and all-cause mortality.
ABSTRACT
INTRODUCTION: oropharyngeal dysphagia (OD) has complications such as malnutrition and dehydration. Body composition is an important factor for nutritional status. OBJECTIVE: to evaluate the presence of cachexia, phase angle, muscle strength, and nutritional risk according to the type of feeding regimen tolerated by patients, determined with the volume-viscosity swallow test (V-VST). METHODS: this cross-sectional study included hospitalized adults of both sexes with a diagnosis of OD established by the Eating Assessment Tool and V-VST. Nutritional risk status was assesed using the Nutritional Risk Screening-2002 tool. Phase angle and cachexia were determined through bioelectrical impedance vector analysis (BIVA), and functional capacity through handgrip strength (HGS) and anthropometric parameters. RESULTS: seventy-nine patients with a median age of 73 years (56-79 yrs) were included; 79.9 % of patients were categorized at nutritional risk. According to the V-VST, 27 (34.2 %) patients tolerated nectar viscosity; 27 (34.2 %) belonged to the spoon-thick and 25 (31.6 %) to the exclusive tube feeding groups. In the exclusive tube feeding group a lower phase angle (3.7° ± 0.9) and lower HGS of 9 kg (5-15) were observed in comparison to the nectar and spoon-thick groups (in both, 4.6° ± 1.1, p = 0.005), which featured 20 kg (16-31) and 19 kg (14-26), respectively (p = 0.03). CONCLUSION: nutritional risk was present in 79.9 % of the study population. BIVA allows to evaluate the integrity of muscle mass and tissue hydration, both related to phase angle. A lower phase angle and HGS were observed in the exclusive tube feeding group. These factors are considered important for prognosis
INTRODUCCIÓN: la disfagia orofaríngea (DO) tiene complicaciones tales como la desnutrición y la deshidratación. La composición corporal es un factor importante en el estado nutricional. OBJETIVO: evaluar la presencia de caquexia, el ángulo de fase (AF), la fuerza muscular y el riesgo nutricional según el tipo de alimentación tolerado por los pacientes de acuerdo con la prueba de exploración clínica del volumen-viscosidad (MECV-V). MATERIAL Y MÉTODOS: estudio transversal de pacientes hospitalizados, con DO determinada por el tamiz Eating Assessment Tool y la MECV-V. El riesgo nutricional se evaluó con la herramienta Nutritional Risk Screening-2002. La composición corporal se determinó mediante impedancia eléctrica y la fuerza de prensión por dinamometría, entre otros parámetros antropométricos. RESULTADOS: se incluyeron 79 pacientes con una mediana de edad de 73 años (56-79 años). El 79,9 % de los pacientes presentaban riesgo nutricional. Según el MECV-V, 27 (34,2 %) toleraron la viscosidad néctar y 27 (34,2 %) la viscosidad puré, y 25 (31,6 %) requirieron alimentación exclusiva por sonda. En el grupo de alimentación por sonda se observaron un AF menor (3,7° ± 0,9) y una fuerza de presión más baja de 9 kg (5-15) en comparación con los grupos de néctar y puré (en los dos parámetros: 4,6° ± 1,1, p = 0,005), con 20 kg (16-31) y 19 kg (14-26) (p = 0,03), respectivamente. CONCLUSIÓN: la impedancia eléctrica permite evaluar la integridad y la hidratación de los tejidos, ambas relacionadas con el AF. Se observó que el AF y la fuerza de prensión fueron menores en el grupo con nutrición exclusiva por sonda. Estos factores se consideran importantes para el pronóstico de estos pacientes

BACKGROUND/OBJECTIVES: Oropharyngeal dysphagia (OD) is a common problem in elderly population that negatively affects the oral intake and body composition resulting in clinical complications as malnutrition and dehydration. The aim of this study was to design, implement, and evaluate the effect of texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume in older adults with OD on body composition and oral intake. SUBJECTS/METHODS: Randomized clinical trial, simple blind. Patients ≥ 65 years, admitted at a national institute, who had a confirmed diagnosis of OD were included. A texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume, was compared to isocaloric standard treatment for 12 weeks. Body composition was evaluated by bioelectrical impedance, muscular functionality was evaluated by handgrip strength, and daily energy and protein intake by 24-h recall and evaluated by Food Processor Nutrition Analysis® software. RESULTS: Twenty participants were included per group, with mean age 76 years. After 12 weeks, the consumption of energy (29 ± 10 to 40 ± 15 kcal/kg, p = 0.009) and protein (1.3 ± 0.6 to 1.8 ± 0.7 g/kg, p = 0.03), as well as phase angle (4.4 ± 1.8 to 5.5 ± 2.5°, p = 0.05), body weight (56 ± 10 to 60 ± 10 kg, p < 0.001), and handgrip strength (18 ± 11 to 21 ± 13 kg, p = 0.004) increased in the intervention group. In control group there were no changes. CONCLUSIONS: The dietary intervention improved oral intake, weight, handgrip strength, and phase angle, which can prevent or limit the nutritional complications associated with the OD.
