[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.

[Immunonutrition, evidence and experiences]. / Inmunonutrición, evidencias y experiencias.

Introduction: Immunonutrition is a science that encompasses aspects related to nutrition, immunity, infection, inflammation and tissue damage. Immunomodulatory formulas have shown benefits in a wide variety of clinical situations. The objective of this work was to review the available evidence in immunonutrition (IN). For this, a bibliographic search has been carried out with the keywords: immunonutrition, arginine, glutamine, nucleotides, omega-3 fatty acids, ERAS, fast-track. Clinical trials, reviews and clinical practice guidelines have been included. IN has been shown to reduce postoperative fistulae in head and neck cancer patients and in gastric and esophageal cancer patients, infectious complications and hospital stay. Other clinical situations that benefit from the use of IN are pancreatic cancer surgery, colorectal cancer surgery and major burns. More controlled, prospective, and randomized studies are necessary to confirm the potential benefits of IN in other clinical situations such as non-esophageal thoracic surgery, bladder cancer, gynecological surgery, hip fracture, liver pathology and COVID-19, among others.

Introducción: La inmunonutrición es una ciencia que engloba aspectos relacionados con la nutrición, la inmunidad, la infección, la inflamación y el daño tisular. Las fórmulas inmunomoduladoras han demostrado beneficios en una amplia variedad de situaciones clínicas. El objetivo de este trabajo es revisar la evidencia disponible en inmunonutrición (IN). Para ello, se ha realizado una búsqueda bibliográfica con las palabras clave: inmunonutrición, arginina, glutamina, nucleótidos, ácidos grasos omega-3, ERAS, fast-track. Se han incluido ensayos clínicos, revisiones y guías de práctica clínica. La IN ha demostrado reducir las fístulas en el postoperatorio en pacientes con cáncer de cabeza y cuello. En pacientes con cáncer gástrico y cáncer de esófago, la IN se asocia a una disminución de las complicaciones infecciosas y la estancia hospitalaria. Otras situaciones clínicas que se benefician del uso de la IN son la cirugía del cáncer de páncreas, la cirugía del cáncer colorrectal y los grandes quemados. Son necesarios más estudios controlados, prospectivos y aleatorizados para confirmar los potenciales beneficios de la IN en otras situaciones clínicas como la cirugía torácica no esofágica, el cáncer vesical, la cirugía ginecológica, la fractura de cadera, la patología hepática y la COVID-19, entre otros.

Fish Oil Enriched Intravenous Lipid Emulsions Reduce Triglyceride Levels in Non-Critically Ill Patients with TPN and Type 2 Diabetes. A Post-Hoc Analysis of the INSUPAR Study.

There are no studies that have specifically assessed the role of intravenous lipid emulsions (ILE) enriched with fish oil in people with diabetes receiving total parenteral nutrition (TPN). The objective of this study was to assess the metabolic control (glycemic and lipid) and in-hospital complications that occurred in non-critically ill inpatients with TPN and type 2 diabetes with regard to the use of fish oil emulsions compared with other ILEs. We performed a post-hoc analysis of the Insulin in Parenteral Nutrition (INSUPAR) trial that included patients who started with TPN for any cause and that would predictably continue with TPN for at least five days. The study included 161 patients who started with TPN for any cause. There were 80 patients (49.7%) on fish oil enriched ILEs and 81 patients (50.3%) on other ILEs. We found significant decreases in triglyceride levels in the fish oil group compared to the other patients. We did not find any differences in glucose metabolic control: mean capillary glucose, glycemic variability, and insulin dose, except in the number of mild hypoglycemic events that was significantly higher in the fish oil group. We did not observe any differences in other metabolic, liver or infectious complications, in-hospital length of stay or mortality.
