ABSTRACT
Introducción: El índice de riesgo nutricional geriátrico es un instrumento simple y exacto que permite identificar a pacientes hospitalizados con este riesgo. Objetivo: Valorar la prevalencia de riesgo nutricional en pacientes ingresados por presentar una enfermedad vascular. Métodos: Se evaluaron de forma transversal 102 pacientes mayores de 18 años (65 % hombres) ingresados de forma consecutiva entre octubre y diciembre de 2018 en el Instituto Nacional de Angiología y Cirugía Vascular en La Habana Cuba, independientemente de la enfermedad de base y que estuvieran de acuerdo en participar en el estudio. La variable principal de salida fue la proporción de pacientes con riesgo nutricional: riesgo alto (< 82), moderado (82-92), bajo (93-98) y sin riesgo (> 98); las variables secundarias resultaron la edad, el sexo, el índice de masa corporal y la concentración de albúmina. Resultados: El 12,9 por ciento (intervalo de confianza 95 por ciento: 6,2-19,6); el 16,8 por ciento (9,4-24,2) y el 22,8 por ciento (14,5-31,3) de los pacientes presentaron un riesgo nutricional alto, moderado y ligero, respectivamente. Solo el 47,5 por ciento (37,6-57,4), de los pacientes no presentó riesgo nutricional. La edad y el sexo no mostraron correlación con el riesgo nutricional; la concentración de albúmina y el índice de masa corporal y el índice de riesgo nutricional sí se asociaron de forma importante (R2: 0,98 y 0,59, respectivamente). Conclusiones: La prevalencia de pacientes con riesgo nutricional es elevada en el ámbito hospitalario y puede evaluarse por intermedio del índice de riesgo nutricional geriátrico(AU)
Introduction: The Geriatric nutritional risk index is a simple and accurate instrument that allows identifying hospitalized patients with this risk. Objective: To assess the prevalence of nutritional risk in patients admitted for presenting a vascular disease. Methods: There were evaluated in cross-sectional way 102 patients older than 18 years (65% male) admitted consecutively from October to December, 2018 at the National Institute of Angiology and Vascular Surgery in Havana, Cuba, regardless of the underlying disease and who agreed to participate in the study. The main variable was the proportion of patients with nutritional risk: high risk (<82), moderate (82-92), low (93-98) and without risk (>98); secondary variables were age, sex, body mass index and the concentration of albumin. Results: The 12.9 percent (95 percent confidence interval: 6,2-19,6); the 16.8 percent (9,4-24,2) and the 22.8 percent (14,5-31,3) of the patients had high, moderate, and light nutritional risks, respectively. Only 47.5 percent (37,6-57,4) of the patients did not present nutritional risk. The age and sex showed no correlation with the nutritional risk; the concentration of albumin and body mass index and the index of nutritional risk were significantly associated (R2: 0.98 and 0.59, respectively). Conclusions: The prevalence of patients with nutritional risk is high in the hospital scope and it can be evaluated through the geriatric nutritional risk index(AU)

INTRODUCTION AND OBJECTIVES: Malnutrition has been shown to affect clinical outcomes in patients with heart failure. The aim of this study was to analyze the impact of preoperative nutritional status assessed by the nutritional risk index (NRI) on the prognosis of patients with a continuous-flow left ventricular assist device (cf-LVAD). METHODS: We performed a retrospective study of 279 patients who underwent cf-LVAD implantation between 2009 and 2015 in our center. Preoperative NRI was calculated and the patients were followed-up for 1 year. The association between preoperative NRI and postoperative clinical events was analyzed using multivariable logistic regression. RESULTS: The prevalence of severe (NRI <83.5), moderate (83.5 ≤ NRI <97.5) and mild (97.5 ≤ NRI <100) nutritional risk was 5.4%, 21.5%, and 9.3%. Mortality rates 1 year after cf-LVAD implantation in these 3 categories were 53.3%, 31.7%, 23.1% vs 18.0% (P <.001) in patients with a normal IRN. A normal preoperative NRI value was an independent predictor of lower risk of death from any cause during follow-up (aHR per 1 unit, 0.961; 95%CI, 0.941-0.981; P <.001) was and a predictor for a lower risk of postoperative infections (aOR, 0.968; 95%CI, 0.946-0.991; P=.007), respiratory failure (aOR, 0,961; 95%CI, 0.936-0.987; P=.004), and right heart failure (aOR, 0.963; 95%CI, 0.934-0.992; P=.014). CONCLUSIONS: Malnourished patients are at increased risk for postoperative complications and death after cf-LVAD implantation. Assessment of nutritional risk could improve patient selection and the early initiation of nutritional support.

INTRODUCTION AND OBJECTIVES: To study the prognostic impact of preoperative nutritional status, as assessed through the nutritional risk index (NRI), on postoperative outcomes after heart transplantation (HT). METHODS: We conducted a retrospective, single-center study of 574 patients who underwent HT from 1991 to 2014. Preoperative NRI was calculated as 1.519 × serum albumin (g/L) + 41.7 × (body weight [kg] / ideal body weight [kg]). The association between preoperative NRI and postoperative outcomes was analyzed by means of multivariable logistic regression and multivariable Cox regression. RESULTS: Mean NRI before HT was 100.9 ± 9.9. According to this parameter, the prevalence of severe nutritional risk (NRI < 83.5), moderate nutritional risk (83.5 ≤ NRI < 97.5), and mild nutritional risk (97.5 ≤ NRI < 100) was 5%, 22%, and 10%, respectively. One year post-transplant mortality rates in these 4 categories were 18.2%, 25.3%, 7.9% and 10.2% (P < .001), respectively. The NRI was independently associated with a lower risk of postoperative infection (adjusted OR, 0.97; 95%CI, 0.95-1.00; P = .027) and prolonged postoperative ventilator support (adjusted OR, 0.96; 95%CI, 0.94-0.98; P = .001). Patients at moderate or severe nutritional risk had significantly higher 1-year post-HT mortality (adjusted HR, 1.55; 95%CI, 1.22-1.97; P < .001). CONCLUSIONS: Malnourished patients have a higher risk of postoperative complications and mortality after HT. Preoperative NRI determination may help to identify HT candidates who might benefit from nutritional intervention.

Se realizó un estudio descriptivo y prospectivo de 11 pacientes con fibrosis quística, atendidos en la consulta integral del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, desde mayo de 2011 hasta febrero de 2012, para evaluar el estado y el índice de riesgo nutricionales, según el protocolo de evaluación para estos casos, a partir del Consenso de Norteamérica (2005). Se utilizó el método estadístico de comparación de proporciones. La mayoría de los afectados fueron clasificados como desnutridos (63,6 %), todos presentaron riesgo nutricional por bajo peso y 3, desnutrición proteicoenergética severa (27,6 %); también se obtuvo que más de la mitad tuvieron mayor morbilidad e ingresos en el período evaluado. Finalmente, el método de evaluación nutricional fue muy útil para determinar grado y tipo de desnutrición, pues el diagnóstico precoz y la intervención nutricional oportuna mejoran la calidad de vida.
A descriptive and prospective study of 11 patients with cystic fibrosis, assisted in the comprehensive department of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago from Cuba was carried out from May, 2011 to February, 2012, to evaluate the status and the nutritional risk index, according to the evaluation protocol for these cases, from the Consensus of North America (2005). The statistical method for comparison of ratios was used. Most of those affected were classified as undernourished (63.6%), all presented nutritional risk due to underweight and 3 had severe protein energy malnutrition (27.6%); it was also obtained that more than half had higher morbidity and admissions in the evaluated period. Finally, the method of nutritional evaluation was very useful to determine degree and type of malnutrition, because the early diagnosis and the opportune nutritional intervention improve the life quality.

In 1999 the Mullen and Buzby's formula was adapted, eliminating hypersensitivity skin tests and removing the alfa factor with coefficients similar to the original, obtaining a new formula called adapted Nutritional Prognostic index (aNPI). Objective: To determine the behavior of this new formula and the nutritional risk index with post surgical complications. Methodology: 110 elective patients for surgery were studied by carrying out pre- and post-operational evaluation. Results: the average age was 50 years old; 52 percent showed signs of being overweight or obese; 89,15 percent had normal serum albumin and 60 percent showed a deficit of transferrine; 75ú percent had low risk NPIa and 62,7 percent had a normal NRI. The main surgeries were hysterectomies and cholecystectomies, 92 percent were without complications (p=0,001). It was found a statistically significant relationship between each classification of nutritional index with the presence o absence of complications (p=0.001). When comparing these indexes, the statistical difference is maintained (p= 0.00). The same was observed when comparing the classification ofthis two indexes with complications (p=0.00). When comparing these two indexes, the multiple regression analysis did not show any significant difference with the type of complication, although there was a significant difference with serum albumin levels and the type of surgery. Conclusion: in this study the a NPI and NRI behaved similarly with the majority of variables under study.
En 1999 se adaptó la formula de Mullen y Buzby suprimiendo las pruebas de hipersensibilidad cutánea removiendo el factor alfa con coeficientes similares a la fórmula original, obteniéndose una nueva fórmula denominada índice de Pronóstico Nutricional adaptado (INPa). Objetivo: Determinar el comportamiento de las fórmulas IPNa e IRN, con complicaciones postquirúrgicas. Metodología: Se estudiaron prospectivamente 110 pacientes de cirugías electivas realizando una valoración prequirúrgica y postquirúrgica. Resultados: La edad promedio fue 50 años; 52 por ciento con sobrepeso y obesidad; 89,15 por ciento la albuminemia fue normal, 60 por ciento con déficit de transferrina. El 75,5 por ciento presentaron un IPNa con bajo riesgo, y 62,7 por ciento un IRN normal. Las cirugías predominantes fueron histerectomías y colecistectomías, 92 por ciento sin complicaciones. Se encontró una relación estadísticamente entre la clasificación de cada uno de los índices nutricionales con la presencia o ausencia de complicaciones (p= 0,001). Al comparar estos dos índices, la diferencia estadística se mantiene (p=0,00), sin embargo, el análisis de regresión múltiple no mostró diferencia significativa de éstos índices con el tipo de complicaciones obteniendo significancia con albuminemia y tipo de cirugía. Conclusión: En este estudio el IPNa y el IRN se comportaron de manera semejante en la mayoría de las variables estudiadas.
