Valoración nutricional por ecografía del recto femoral y el tejido adiposo preperitoneal como predictores del riesgo de complicaciones del paciente hospitalizado / Nutritional assessment by ultrasound of the rectus femoris and preperitoneal adipose tissue as predictors of hospitalized patient complications

Introducción La desnutrición y la sarcopenia se asocian al aumento del riesgo de eventos adversos y peor evolución en los pacientes hospitalizados. La ecografía constituye una herramienta de utilidad en la evaluación de la composición corporal. Pacientes y métodos Se reclutaron 23 pacientes ingresados en una planta de hospitalización. Se recogieron las variables ecográficas del tejido muscular y tejido adiposo, así como su variación durante el ingreso. Correlacionándose con datos antropométricos, clínicos y analíticos. Resultados Observamos una correlación de las mediciones ecográficas con la duración de la hospitalización (grasa preperitoneal máxima: −0,585, grosor del recto femoral [RF]: −0,539, área del RF: −0,540), la fragilidad (RF: −0,599) y la dependencia (RF: 0,628). La capacidad de contracción del RF se correlacionó con el ejercicio semanal reportado (0,642). Conclusión El grosor del RF y de la grasa preperitoneal se correlacionan con el número de días de ingreso y la capacidad funcional, erigiéndose como variables pronósticas (AU)

Introduction Malnutrition and sarcopenia are associated with increased risk of adverse events and worse outcome in hospitalised patients. Ultrasonography is a useful tool in the assessment of body composition. Patients and methods Twenty-three patients admitted to a hospital ward were recruited. Ultrasonographic variables of muscle tissue and adipose tissue were collected, as well as their variation during admission. These were correlated with anthropometric, clinical and analytical data. Results We observed a correlation of ultrasound measurements with length of hospitalisation (maximum preperitoneal fat −0.585, rectus femoris thickness [RF] −0.539, RF area −0.540), frailty (RF −0.599) and dependency (RF 0.628). RF contractile capacity correlated with reported weekly exercise (0.642). Conclusion RF and preperitoneal fat thickness correlate with the number of days of admission and functional capacity, emerging as prognostic variables (AU)

Nutritional assessment by ultrasound of the rectus femoris and preperitoneal adipose tissue as predictors of hospitalized patient complications.

INTRODUCTION: Malnutrition and sarcopenia are associated with increased risk of adverse events and worse outcome in hospitalised patients. Ultrasonography is a useful tool in the assessment of body composition. PATIENTS AND METHODS: Twenty-three patients admitted to a hospital ward were recruited. Ultrasonographic variables of muscle tissue and adipose tissue were collected, as well as their variation during admission. These were correlated with anthropometric, clinical and analytical data. RESULTS: We observed a correlation of ultrasound measurements with length of hospitalisation (maximum preperitoneal fat -0.585, rectus femoris thickness - RF -0.539, RF area -0.540), frailty (RF -0.599) and dependency (RF 0.628). RF contractile capacity correlated with reported weekly exercise (0.642). CONCLUSION: RF and preperitoneal fat thickness correlate with the number of days of admission and functional capacity, emerging as prognostic variables.
