[Organoleptic evaluation of a diabetes-specific oral nutritional supplement with extra virgin olive oil in patients at nutritional risk and type 2 diabetes mellitus: Double-blind, randomized, crossover and multicenter clinical trial (DIACARE)]. / Evaluación sensorial de un suplemento nutricional oral específico para diabetes con aceite de oliva virgen extra en pacientes en riesgo nutricional y diabetes mellitus tipo 2: ensayo clínico doble ciego, aleatorizado, cruzado y multicéntrico (DIACARE.

Introduction: Introduction: oral nutritional supplements specific for diabetes (DSF) usually have a composition that favors their palatability and simultaneous glycemic and metabolic control. Objetive: to compare the sensory acceptability of a DSF with respect to a standard oral nutritional supplement (STF) in patients at risk of malnutrition with type 2 diabetes mellitus. Method: randomized, double-blind, crossover, multicenter, controlled, double-blind clinical trial. Odor, taste and perceived texture of a DSF and a STD were evaluated using a scale of 1 to 4. Results: twenty-nine patients were recruited and 58 organoleptic evaluations of the supplements were registered. A better evaluation of DSF was observed with respect to STD, although no statistically significant differences were reached: odor, 0.04 (CI 95 %) -0.49 to 0.56 (p = 0.092); taste, 0.14 (CI 95 %), -0.35 to 0.63 (p = 0.561); texture, 0.14 (CI 95 %), -0.43 to 0.72 (p = 0.619). No differences were found when analyzed by order of randomization, sex, degree of malnutrition, greater or lesser degree of complexity, greater or lesser time of evolution of diabetes, or by being older or younger. Conclusions: the specific nutritional supplement for diabetic patients formulated with extra virgin olive oil, EPA and DHA, a specific mixture of carbohydrates, and fiber, presented an adequate sensory acceptance by malnourished patients with type 2 diabetes mellitus.

Introducción: Introducción: las fórmulas nutricionales específicas para diabetes (FED) suelen presentar una composición que favorece simultáneamente su palatabilidad y el control glucémico y metabólico. Objetivo: comparar la aceptación sensorial de un FED respecto a un suplemento nutricional oral estándar (FE) en pacientes en riesgo de desnutrición con diabetes mellitus tipo 2. Método: ensayo clínico, aleatorizado, doble ciego, cruzado, multicéntrico y controlado. Se evaluó, a través de una escala del 1 al 4, el olor, el sabor y la textura percibida de un FED y de un FE. Resultados: se reclutaron a 29 pacientes y 58 evaluaciones sensoriales de los suplementos. Se observó una mejor valoración de la FED respecto a la FE, aunque no se alcanzaron diferencias estadísticamente significativas: olor, 0,04 (IC 95 %), de -0,49 a 0,56 (p = 0,092); sabor, 0,14 (IC 95 %), de -0,35 a 0,63 (p = 0,561); textura, 0,14, (IC 95 %), de -0,43 a 0,72 (p = 0,619). No se encontraron diferencias cuando se analizaron por orden de aleatorización, sexo, grado de desnutrición, mayor o menor grado de complejidad, mayor o menor tiempo de evolución de la diabetes, ni por ser más o menos mayores. Conclusiones: el suplemento nutricional específico para paciente con diabetes, formulado con aceite de oliva virgen extra, EPA y DHA, una mezcla específica en hidratos de carbono, fibra soluble e insoluble, presentó una adecuada aceptación sensorial del paciente desnutrido con diabetes mellitus tipo 2.

Glycaemic and insulinaemic impact of a diabetes-specific oral nutritional supplement with extra-virgin olive oil in patients with type 2 diabetes mellitus at nutritional risk: a randomized, double-blind, crossover, multicentre clinical trial (DIACARE).

Introduction: Introduction: there is controversy about the usefulness of specific enteral nutrition formulas in malnourished patients with diabetes. The effects on blood glucose and other aspects of metabolic control are not fully understood in the scientific literature. Objective: the aim of the study was to compare the glycaemic and insulinaemic response of patients with type 2 diabetes at risk of malnutrition after oral feed between a diabetes-specific formula with AOVE (DSF) and a standard one (STF). Methods: A randomized, double-blind, crossover, multicentre clinical trial was conducted in patients with type 2 diabetes at risk of malnutrition (SGA). The patients were randomized to receive either DSF or STF, a week apart. A glycaemia and insulinaemia curve was made at times 0 minutes, 30 min, 60 min, 90 min, 120 min, and 180 min after the patients drank 200 ml of the oral nutritional supplement (ONS). The principal variables were the area under the curve (AUC0-t) of glucose and insulin. Results: 29 patients (51 % women) were included, who were on average 68.84 (SD 11.37) years old. Regarding the degree of malnutrition, 86.2 % presented moderate malnutrition (B) and 13.8 % severe (C). When the patients received the DSF, they had a lower mean of glucose AUC0-t (-3,325.34 mg/min/dl [95 % CI: -4,3608.34 to -2,290.07]; p = 0.016) and also a lower mean of insulin AUC0-t (-451.14 uU/min/ml [95 % CI: -875,10 to -27.17]; p = 0.038). There were no differences in the degree of malnutrition. Conclusion: compared with STF, DSF with AOVE showed a better glycaemic and insulinaemic response in patients with type 2 diabetes at risk of malnutrition.

Introducción: Introducción: la utilidad de las fórmulas específicas de nutrición enteral en el paciente desnutrido con diabetes resulta controvertida. Sus efectos sobre la glucosa en sangre y otros aspectos del control metabólico no se conocen del todo en la literatura científica. Objetivo: el objetivo del estudio fue comparar la respuesta glucémica e insulinémica de los pacientes con diabetes tipo 2 (DM2) en riesgo de desnutrición tras la ingesta oral de una fórmula específica para diabetes (DSF) con aceite de oliva virgen extra (AOVE) y una estándar (STF). Métodos: ensayo clínico aleatorizado, doble ciego, cruzado y multicéntrico enpacientes con DM2 en riesgo de desnutrición (SGA). Los pacientes se asignaron aleatoriamente para recibir DSF o STF con una semana de diferencia. Se realizó una curva de glucemia e insulinemia en los siguientes tiempos: 0 minutos, 30 min, 60 min, 90 min, 120 min y 180 min tras la ingesta de 200 ml del suplemento nutricional oral (SNO). Las variables principales fueron el área bajo la curva (AUC0-t) de glucosa e insulina. Resultados: se incluyeron 29 pacientes (51 % mujeres), con una edad media de 68,84 años (DE 11,37). En cuanto al grado de desnutrición, el 86,2 % presentaba desnutrición moderada (B) y el 13,8 %, severa (C). Cuando los pacientes recibieron DSF tuvieron una media más baja de AUC0-t de glucosa (-3325,34 mg/min/dl [IC 95 %: de -4.3608,34 a -2.290,07]; p = 0,016) y también una media más baja de AUC0-t de insulina (-451,14 uU/min/ml [IC 95 %: de -875,10 a -27,17]; p = 0,038) respecto a cuando recibieron STF. No hubo diferencias por el grado de desnutrición. Conclusión: la fórmula con AOVE específica para diabetes mostró una mejor respuesta glucémica e insulinémica en pacientes con diabetes tipo 2 en riesgo de desnutrición respecto a una fórmula estándar.

Nutritional ultrasound®: Conceptualisation, technical considerations and standardisation.

Nutritional ultrasound® is a new concept that uses ultrasound to assess body composition. It is composed of the evaluation of fat-free mass and fat mass. It is an emerging, economical, portable, non-invasive technique that evaluates the musculoskeletal area with linear, broadband, multifrequency probes, with a depth field of 20-100mm. It quantifies muscle modifications in malnutrition and provides information on functional changes (echogenicity). Although there are no validated specific cut-off points, the anterior rectum area of the quadriceps can be used as a criterion for malnutrition. The distribution of adipose tissue provides information on the energy reserve and the inflammatory pattern. It is important to integrate nutritional ultrasound® measures in clinical practice adapted to different settings and pathologies. It is necessary to establish training plans in nutritional ultrasound® for use by Endocrinology and Nutrition Specialists, with the aim of improving the diagnosis and treatment of their patients.

Rectus Femoris Muscle and Phase Angle as Prognostic Factor for 12-Month Mortality in a Longitudinal Cohort of Patients with Cancer (AnyVida Trial).

BACKGROUND: Cancer-related malnutrition is still unrecognized and undertreated in clinical practice. The morphofunctional assessment of disease-related malnutrition (DRM) is a new approach that focuses on evaluating changes in body composition and function. The aim of this study is to evaluate the prognostic value of classic and emerging assessment of malnutrition at 12-months survival in cancer patients. METHODS: We conducted a prospective study on cancer outpatients. Bioelectrical impedance with phase angle (PhA), nutritional ultrasound by rectus femoris cross-sectional area (RFCSA), hand grip strength, and "Timed Up and Go Test" (TUG) were evaluated as predictors of mortality. RESULTS: Fifty-seven patients were included. The non-survivors had lower PhA values than the survivors (4.7° vs. 5.4°; p < 0.001), and we had the same results with RFCSA 2.98 cm2/m2 vs. 4.27 cm2/m2 (p = 0.03). Cut-off points were identified using the ROC (receiver operating characteristic) curves for PhA (≤5.6° cancer patients, ≤5.9° men, ≤5.3° women), RFCSA (≤4.47 cm2/m2 cancer patients, ≤4.47° men, ≤2.73° women) and rectus femoris-Y-axis (RF-Y-axis; ≤1.3 cm cancer patients, ≤1.06 men, ≤1 women). In multivariate logistic regression analysis, we found that high PhA was significantly associated with a lower mortality hazard ratio (HR: 0.42 95% CI: 0.21-0.84, p = 0.014). Likewise, high RFCSA was associated with a decrease in mortality risk in the crude model (HR: 0.61 95% CI: 0.39-0.96, p = 0.031). This trend was also maintained in the adjusted models by the confounding variables. CONCLUSIONS: Low PhA and RFCSA values are significant independent predictors of mortality in cancer patients. These cut-off points are clinical data that can be used for nutritional assessment and the prediction of clinical outcomes.

Predictors of Sarcopenia in Outpatients with Post-Critical SARS-CoV2 Disease. Nutritional Ultrasound of Rectus Femoris Muscle, a Potential Tool.

Background and Objectives: The loss of muscle mass in post-critical COVID-19 outpatients is difficult to assess due to the limitations of techniques and the high prevalence of obesity. Ultrasound is an emerging technique for evaluating body composition. The aim is to evaluate sarcopenia and its risk factors, determining ultrasound usefulness as a potential tool for this purpose according to established techniques, such as the bioimpedance vector analysis (BIVA), handgrip strength, and timed up-and-go test. Methods: This is a transversal study of 30 post-critical COVID-19 outpatients. We evaluated nutritional status by ultrasound (Rectus Femoris-cross-sectional-area (RF-CSA), thickness, and subcutaneous-adipose-tissue), BIVA, handgrip strength, timed up-and-go test, and clinical variables during admission. Results: According to The European Society for Clinical Nutrition and Metabolism and the European Association for the Study of Obesity (ESPEN&EASO) Consensus for Sarcopenic and Obesity, in terms of excess fat mass and decreased lean mass, the prevalence of class-1 sarcopenic obesity was 23.4% (n = 7), and class-2 sarcopenic obesity was 33.3% (n = 10) in our study. A total of 46.7% (n = 14) of patients had a handgrip strength below the 10th percentile, and 30% (n = 9) achieved a time greater than 10s in the timed up-and-go test. There were strong correlations between the different techniques that evaluated the morphological (BIVA, Ultrasound) and functional measurements of muscle. Intensive care unit stay, mechanical ventilation, and age all conditioned the presence of sarcopenia in COVID-19 outpatients (R2 = 0.488, p = 0.002). Predictive models for sarcopenic diagnosis based on a skeletal muscle index estimation were established by RF-CSA (R2 0.792, standard error of estimate (SEE) 1.10, p < 0.001), muscle-thickness (R2 0.774, SEE 1.14, p < 0.001), and handgrip strength (R2 0.856, SEE 0.92, p < 0.001). RF-CSA/weight of 5.3 cm2/kg × 100 was the cut-off value for predicting sarcopenia in post-critical COVID-19 outpatients, with 88.2 sensitivity and 69.2% specificity. Conclusion: More than half of the post-critical COVID-19 survivors had sarcopenic obesity and functional impairment of handgrip strength. Intensive care unit stay, age, and mechanical ventilation all predict sarcopenia. An ultrasound, when applied to the assessment of body composition in post-critical COVID-19 patients, provided the possibility of assessing sarcopenia in this population.

Effect on an Oral Nutritional Supplement with ß-Hydroxy-ß-methylbutyrate and Vitamin D on Morphofunctional Aspects, Body Composition, and Phase Angle in Malnourished Patients.

This is a retrospective study of data from clinical practice to observe the effect of a high-calorie, high-protein oral nutritional supplement (ONS) with ß-hydroxy-ß-methylbutyrate (HMB) on nutritional status, body weight, and muscle-related parameters in 283 adult patients with or at risk of malnutrition under standard of care, 63% being cancer patients. They were recommended to increase physical activity and energy and protein intake from regular diet plus two servings per day of a specialized ONS enriched with HMB or standard ONS for up to 6 months. Dietary records, adherence and tolerance to ONS, nutritional status, body composition, handgrip strength, and blood analysis at the beginning and the end of the intervention were recorded. This program improved nutritional status from 100% malnourished or at risk of malnutrition at baseline to 80% well-nourished at final visit. It also increased body weight by 3.6-3.8 kg, fat-free mass by 0.9 to 1.3 kg, and handgrip strength by 4.7 to 6.2 kg. In a subgroup of patients (n = 43), phase angle (PhA), and body cell mass (BCM) increased only in the patients receiving the ONS enriched with HMB (0.95 (0.13) vs. -0.36 (0.4), and 2.98 (0.5) vs. -0.6 (1.5) kg, mean difference (SE) from baseline for PhA and BCM, respectively), suggesting the potential efficacy of this supplement on muscle health.

Morphofunctional assessment of patient's nutritional status: a global approach / Evaluación morfofuncional del estado nutricional de los pacientes: un nuevo enfoque

Disease-related malnutrition represents an imbalance between the intake and the requirements of energy and nutrients. It produces a series of metabolic and functional changes in the body. There are multiple limitations in the classic parameters for nutrition assessment including body mass index, weight loss, food intake, or standard laboratory parameters such as albumin or lymphocytes. We can establish some points of interest in this new approach to nutrition focused on the assessment of nutritional status by evaluating changes in composition and function using parameters such as PhA and other electrical measurements of bioimpedance, dynamometry, functional tests, muscle ultrasound, or laboratory parameters such as CRP/prealbumin.Each of these parameters has a number of uses and limitations that should be understood when evaluating its ability to diagnose malnutrition as related to disease, its concordance with other tests, and its prognostic value. Emerging nutritional param­eters for future use should be sensitive, specific, and interrelated to allow a better understanding of each patient's status at different time points during their disease.

La nueva visión global de la nutrición clínica debería integrar diferentes aspectos de composición y función del organismo para poder establecer un diagnóstico más preciso de la situación nutricional y un plan terapéutico individualizado. Los parámetros nutricionales emergentes deben ser sensibles y específicos, y estar relacionados entre sí, de forma que permitan un mejor conocimiento de la situación particular de cada paciente en los diferentes momentos evolutivos de su proceso patológico.
