Assessment of body composition in cystic fibrosis: agreement between skinfold measurement and densitometry / Evaluación de la composición corporal en adultos con fibrosis quística: concordancia entre la densitometría y la antropometría

Introduction: few studies have evaluated body composition (BC) through different techniques, and the degree of agreement between them in adults with cystic fibrosis (CF). Objectives: to describe BC using techniques to assess nutritional status and to test their concordance in CF. Methods: a cross-sectional study in CF patients in a clinically stable situation. Nutritional assessment was performed using skinfold measurement (SM) and densitometry (DXA). Fat-free mass index (FFMI) was also determined. The diagnosis of malnutrition was established if body mass index (BMI) < 18.5 kg/m2. Fat-free mass (FFM) malnutrition was diagnosed when FFMI was < 17 kg/m2 in males and < 15 kg/m2 in females (FFMI: fat-free mass in kg/height in m2). Results: forty-one patients were studied (twenty-two females, 53.7 %); median age was 29.8 (interquartile range, 20.9-33.7); BMI was 21.6 (19.8-23.0). Only four (9.8 %) patients had a BMI < 18.5. By DXA, FFM (kg) results were: median, 52.8 (47.8-56.9) with FFMI of 17.9 (16.7-19.3) in males and 36.7 (33.1-38.9) in females, FFMI of 14.7 (14.2-15.8). Twenty (48.6 %) patients presented FFM malnutrition, with 16.7 % of males and 59.1 % of females being affected. By SM, the FFMI was 18.7 (17.2-20.0) in males and 14.9 (14.2-15.8) in females; moreover, sixteen (39.1 %) patients presented malnutrition of FFM, with 20.8 % of males and 61.8 % of females being affected. For FFM (kg), high concordance was obtained between SM and DXA (intraclass correlation coefficient of 0.950); likewise when they were compared by applying the ESPEN criteria for FFM malnutrition. However, when the techniques were compared to classify malnutrition according to FFMI, the kappa coefficient was only moderate (k = 0.440). The mean difference between FFM by DXA and SM was +1.44 ± 0.62 kg in favor of SM, with greater dispersion as FFM increased. Conclusions: the prevalence of FFM malnutrition is high in adult CF patients, despite a normal BMI, especially in females (AU)

Introducción: pocos estudios han evaluado la composición corporal (BC) mediante diferentes técnicas y el grado de concordancia entre ellas en adultos con fibrosis quística (FQ). Objetivos: describir la BC mediante técnicas de evaluación Nutricional y comprobar su concordancia en la FQ. Métodos: estudio transversal de adultos con FQ en situación de estabilidad clínica. La evaluación Nutricional se realizó mediante medición de pliegues cutáneos (SM) y densitometría (DXA). También se determinó el índice de masa libre de grasa (FFMI). El diagnóstico de desnutrición se estableció si el índice de masa corporal (IMC) era < 18,5 kg/m2. Se diagnosticó desnutrición por masa libre de grasa (FFM) cuando el FFMI era < 17 kg/m2 en los hombres y < 15 kg/m2 en las mujeres (FFMI: masa libre de grasa en kg/estatura en m2). Resultados: se estudiaron cuarenta y un pacientes (veintidós mujeres (53,7 %), con una edad media de 29,8 años (rango intercuartílico, 20,9-33,7) y un IMC de 21,6 (19,8-23,0). Solo cuatro (9,8 %) pacientes tenían un IMC < 18,5. Mediante DXA, los resultados de FFM (kg) fueron (mediana y RIC): 52,8 (47,8-56,9) con FFMI de 17,9 (16,7-19,3) en los varones y 36,7 (33,1-38,9) en las mujeres con FFMI de 14,7 (14,2-15,8). Veinte (48,6 %) pacientes presentaban desnutrición del FFM, con el 16,7 % de varones y el 59,1 % de mujeres afectados. Mediante el SM, el FFMI fue de 18,7 (17,2-20,0) en los varones y de 14,9 (14,2-15,8) en las mujeres; además, dieciséis (39,1 %) pacientes presentaban malnutrición del FFMI, con el 20,8 % de varones y el 61,8 % de mujeres afectados. En el caso de la FFM (kg), se obtuvo una alta concordancia entre el SM y la DXA (coeficiente de correlación intraclase de 0,950); igualmente cuando se compararon las técnicas aplicando los criterios ESPEN para la desnutrición de la FFM. Sin embargo, cuando se compararon las técnicas para clasificar la malnutrición según el FFMI, el coeficiente kappa fue solo moderado (coeficiente kappa = 0,440) (AU)

Osteopenia and Osteoporosis in Patients with Bronchiectasis: Association with Respiratory Parameters, Body Composition, Muscle Strength and Bone Remodeling Biomarkers.

The prevalence of osteopenia/osteoporosis has not been sufficiently studied in people with bronchiectasis not due to cystic fibrosis (BC), nor has its relationship with other variables (clinical, body composition and bone turnover and inflammation markers) been sufficiently studied. Our aim was to determine the prevalence of osteopenia and osteoporosis and related factors in patients with BC. We did a cross-sectional study in people with BC in a clinically stable state. Spirometric parameters, annual exacerbations and analysis with bone turnover markers (BTM) and inflammation markers were evaluated. Densitometry (DXA) was performed for body composition, bone mineral density (BMD) and handgrip strength. 123 patients were studied (65% women, mean age 49.6 ± 18.8, Body Mass Index (BMI) 24.8 ± 4.7 kg/m2). 62.8% and 62.5% of men and women, respectively, had normal bone mineral density, 30.2% and 22.2% osteopenia and 7% and 15% osteoporosis. 52 patients (56.2%) had low fat-free mass: 68.9% women and 28.6% men. Patients with decreased bone mass had significantly lower muscle strength, maximum expiratory volume in the first second (FEV1%), vitamin D, higher levels of C-terminal telopeptide of type 1 collagen (CTX) and total osteocalcin and underarboxylated osteocalcin (ucOC). We observed significant and negative correlations between BMD and the number of serious exacerbations per year CTX and undercarboxylated osteocalcin. We observed significant positive correlations between BMD, fat free mass index (FFMI) and handgrip dynamometry. The study suggest that the prevalence of osteoporosis was high in relation to the demographic characteristics. Respiratory parameters, body composition, muscle strength and bone remodeling markers were associated with a lower bone mineral density.

Efecto de la rehabilitación respiratoria asociada a suplementación nutricional sobre la actividad física en pacientes con bronquiectasias: estudio aleatorizado / The effect of pulmonary rehabilitation associated with nutritional supplementation on physical activity in patients with bronchiectasis: randomized trial

Introducción: la actividad física está fuertemente relacionada con la mortalidad y la situación respiratoria en patologías respiratorias como la enfermedad pulmonar obstructiva crónica (EPOC) y la fibrosis quística (FQ). Los programas de rehabilitación respiratoria (RR) han demostrado mejorar el grado de actividad física en pacientes con EPOC. No existen trabajos específicos en pacientes con bronquiectasias (BQ). Objetivos: comparar el efecto sobre la actividad física de la RR durante 12 semanas, comparado con RR más un suplemento hiperproteico enriquecido en beta-hidroxi-beta-metilbutirato (HMB) en pacientes con BQ no debidas a FQ. Material y métodos: estudio prospectivo aleatorizado, en el que se aplica un programa de RR estructurado a pacientes con BQ durante tres meses. A uno de los grupos, además, se le asoció un suplemento hiperproteico con HMB. Se valoró el grado de actividad física en situación basal, a los tres y seis meses mediante acelerómetro wGT3X (ActiGraph) y cuestionario IPAQ. Se analizaron los datos mediante una Anova de medidas repetidas (intención de tratar). Resultados: se incluyeron 30 pacientes con BQ no debidas a FQ (15 en cada rama) sin diferencias en variables clínicas entre los grupos. Después de la intervención, un porcentaje significativo de pacientes incrementaron la actividad física medida mediante el cuestionario IPAQ en el grupo suplementado a los 3 y 6 meses. No se observaron diferencias significativas en función del tipo de intervención. En ambos grupos se observó un discreto aumento de la actividad física de intensidad moderada medida por acelerómetro, a los 3 y 6 meses, pero no alcanzó significación estadística. Conclusiones: la RR, unida a suplementación nutricional en pacientes con BQ no debidas a FQ, aumentó el nivel de actividad física medida mediante el cuestionario IPAQ (a los 3 y 6 meses). Sin embargo, no alcanzó la significación estadística mediante acelerómetro. Son necesarios más estudios que evalúen la validez de los diferentes instrumentos de medida

Introduction: physical activity is closely related to mortality and respiratory status for respiratory diseases such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF).Pulmonary rehabilitation (PR) programs have been shown to improve the level of physical activity in COPD patients. There are no specific studies on patients with bronchiectasis. Objectives: study the effect of PR on physical activity over 12 weeks, in comparison with PR plus a hyperproteic supplement enriched in beta-hydroxy-beta-methylbutyrate (HMB) in patients with non CF bronchiectasis. Material and methods: prospective, randomized study in which a structured PR program is applied in bronchiectasis patients for three months. Additionally, one of the groups received a hyperproteic supplement with HMB. The degree of physical activity was evaluated at baseline and after three and six months using the wGT3X (ActiGraph) accelerometer and the IPAQ (International Physical Activity Questionnaire).Data was analyzed using a repeated measures ANOVA (intention to treat). Results: 30 patients with non-CF bronchiectasis (15 in each group)were included, without differences in clinical variables between groups. After intervention, a significant percentage of patients in the supplement group increased their average physical activity according to the IPAQ after 3 and 6 months. Significant differences depending on type of intervention were not observed. A slight increase in average moderate intensity physical activity measured by accelerometer was observed at 3 and 6 months, but it did not reach statistical significance. Conclusions: PR, along with nutritional supplements, in non-CF bronchiectasis patients increased the level of physical activity measured by the IPAQ (at 3 and 6 months).However, it did not reach statistical significance according to accelerometer measurements. Further studies are needed to evaluate the validity of the different measurement instruments

Depression and anxiety symptoms in Spanish adult patients with cystic fibrosis: associations with health-related quality of life.

BACKGROUND: Cystic fibrosis (CF) is a chronic disease with an impact on the quality of life. Self-reported symptoms of depression and anxiety were assessed in the Spanish cohort of the International Epidemiological Study on Depression and Anxiety in patients with CF (International Depression-Anxiety Epidemiological Study) and their relationship with health status and health-related quality of life (HRQoL) was evaluated. METHODS: This cross-sectional study recruited adult patients with CF at 10 Spanish centers. Patients completed the Hospital Anxiety and Depression Scale (HADS) and the Revised Cystic Fibrosis Questionnaire. Demographic and health data were recorded from medical charts. Logistic regression was used to determine the predictors of elevated symptoms of depression and anxiety (HADS≥8). RESULTS: Of the 336 participants recruited (mean age, 28.1years; 48.2% women), 41 (12.2%) had elevated depression-related scores, and 100 (29.7%) had elevated anxiety-related scores (HADS≥8). After adjusting for confounders, only less education, intravenous antibiotics, psychiatric medications and psychotherapy were significantly associated with elevated psychological symptoms. Specifically, regardless of lung function, patients who were depressed or anxious reported worse HRQoL. CONCLUSIONS: The prevalence of elevated symptoms of depression and anxiety was high in Spanish adult patients with CF, and these symptoms were associated with a decreased HRQoL.

Hypovitaminosis D and incidence of obesity: a prospective study.

The aim of this study was to assess the relationship between obesity and vitamin D status cross-sectionally, the relationship between obesity and the incidence of hypovitaminosis D prospectively and inversely the relationship between vitamin D status and incidence of obesity in a population-based cohort study in Spain. At baseline (1996-1998), 1226 subjects were evaluated and follow-up assessments were performed in 2002-2004 and 2005-2007, participants undergoing an interview and clinical examination with an oral glucose tolerance test. At the second visit, 25-hydroxyvitamin D and intact parathyroid hormone concentrations were also measured. Prevalence of obesity at the three visits was 28.1, 36.2 and 39.5%, respectively. The prevalence of vitamin D deficiency (25-hydroxyvitamin D ≤ 20 ng/ml (≤ 50 nmol/l)) was 34.7%. Neither obesity at baseline (OR=0.98, 95% CI: 0.69-1.40, P=0.93) nor the development of obesity between baseline and the second evaluation (OR=0.80, 95% CI: 0.48-1.33, P=0.39) were significantly associated with vitamin D status. In subjects who were non-obese (BMI <30 kg/m²) at the second evaluation, 25-hydroxyvitamin D values ≤ 17 ng/ml (≤ 42.5 nmol/l) were significantly associated with an increased risk of developing obesity in the next 4 years (OR=2.35, 95% CI: 1.03-5.4, P=0.040 after diverse adjustments). We conclude that vitamin D deficiency is associated with an increased risk of developing obesity.

Recommendations of the GARIN group for managing non-critically ill patients with diabetes or stress hyperglycaemia and artificial nutrition / Recomendaciones del grupo GARIN para el manejo de pacientes no críticos con diabetes o hiperglucemia de estrés y nutrición artificial

Background & aims: By means of this update, the GARIN working group aims to define its position regarding the treatment of patients with diabetes or stress hyperglycaemia and artificial nutrition. In this area there are many aspects of uncertainty, especially in non-critically ill patients. Methods: Bibliographical review, and specific questions in advance were discussed and answered at a meeting in the form of conclusions. Results: We propose a definition of stress hyperglycaemia. The indications and access routes for artificial nutrition are no different in patients with diabetes/stress hyperglycaemia than in non-diabetics. The objective must be to keep pre-prandial blood glucose levels between 100 and 140 mg/dl and post-prandial levels between 140 and 180 mg/dl. Hyperglycemia can be prevented through systematic monitoring of capillary glycaemias and adequately calculate energy-protein needs. We recommend using enteral formulas designed for patients with diabetes (high monounsaturated fat) to facilitate metabolic control. The best drug treatment for treating hyperglycaemia/diabetes in hospitalised patients is insulin and we make recommendations for adapt the theoretical insulin action to the nutrition infusion regimen. We also addressed recommendations for future investigation. Conclusions: This recommendations about artificial nutrition in patients with diabetes or stress hyperglycaemia can add value to clinical work (AU)

Introducción y objetivos: En el tratamiento de los pacientes con diabetes o hiperglucemia de estrés y la nutrición artificial existen muchas áreas de incertidumbre, sobre todo en pacientes no críticos. El grupo de trabajo GARIN tiene como objetivo definir su posición en este campo. Material y métodos: Revisión bibliográfica previa y reunión presencial en la que se discutieron y contestaron preguntas específicas sobre el tema. Resultados: Proponemos una definición de hiperglucemia de estrés. Las indicaciones y las rutas de acceso a la nutrición artificial no difieren en los pacientes con hiperglucemia de estrés o diabetes respecto a los no diabéticos. El objetivo debe ser mantener los niveles de glucemia preprandial entre 100 y 140 mg/dl y postprandial entre 140 y 180 mg/dl. La hiperglucemia puede prevenirse a través de una monitorización sistemática de las glucemias capilares y un cálculo adecuado de las necesidades energético-proteicas. Recomendamos el uso de fórmulas enterales diseñadas para pacientes con diabetes (alto contenido en grasas monoinsaturadas) para facilitar el control metabólico. El mejor tratamiento farmacológico para tratar la hiperglucemia/diabetes en pacientes hospitalizados es la insulina, aconsejando adaptar la acción teórica de la insulina al régimen de infusión de la nutrición. También realizamos recomendaciones para investigaciones futuras. Conclusiones: Estas recomendaciones aportan respuestas concretas sobre cuestiones comunes en la asistencia a pacientes con diabetes o hiperglucemia de estrés y nutrición artificial (AU)

Diarrea crónica refractaria y mal absorción secundaria a hipogammaglobulinemia común variable, infestación crónica por giardialambila y gastrectomía total por adenocarcinoma gástrico: un manejo nutricional complejo / Chonic diarrhea and malabsorption due to common variable immunodeficiency, gastrectomy and giardiasis infection: a difficult nutritional management

El adenocarcinoma gástrico es una de las causas más frecuentes de mortalidad en el mundo, siendo la cirugía el único tratamiento potencialmente curativo, aunque los efectos adversos digestivos y nutricionales son frecuentes y abundantes. La hipogammaglobulinemia variable comunes causa de frecuentes manifestaciones digestivas, derivándose las más importantes en diarrea crónica causada porgiardiasis, hiperplasia nodular linfoide o atrofia vellosa, siendo frecuente la mal absorción y la desnutrición. Los déficits nutricionales secundarios a la mal absorción (postgastrectomía y asociada a la atrofia vellosa y la giardiasis por hipogammaglobulinemia variable común) son asi mismo frecuentes. Presentamos el caso de un paciente gastrectomizado por adenocarcinoma gástrico y con hipogammaglobulinemia variable común e infestación crónica por giardiasis que presenta una importante diarrea crónica refractaria a tratamiento y mal absorción (AU)

Gastric cancer is a frequent cause of cancer-related mortality in the world. Surgery is the only potentially curative therapy, although the adverse effects of surgery are common and considerable. Common variable immunodeficiency is in many cases cause of gastro intestinal system problems such as chronic diarrhea caused by infestation with giardia lamblia, nodular lymphoid hiperplasia ad loss of villi leading frequently to malapsortion and malnutrition. Nutritional deficiencies due to malapsorption (postgastrectomy and secondary to loss of villi, giardiasis andc ommon variable immunodeficiency ) are common. We present the case of a patient with gastric cancer who underwent a gastrectomy with common variable hipogammaglobulinemia and chronic infestation by giardia lamblia, with serious diarrhea resistant to treatment and malabsorption (AU)

It has been well documented in medical literature that hyponutrition is a common issue at all healthcare levels, from primary to specialized health care, as well as geriatric healthcare facilities. This problem is not limited to countries with scarce economic resources or limited social development; it is also a universal issue in Europe. Hyponutrition increases the rates of morbidity, mortality, hospital admissions, and hospital stay. These higher figures also represent a higher use of healthcare resources. In spite of this, hyponutrition may often go undetected and the patient may not receive the necessary treatment. This problem requires the cooperation of multiple agents such as the Governments, the healthcare professionals, and the citizens themselves. The VIII Discussion Forum concludes on the need to establish a clear-cut plant for action (similar to the European Alliance for Health Nutrition) and the creation of a platform (coalition) encompassing the voices of healthcare professionals associations, institutions, professional colleges, patients associations, the pharmaceutical companies, and insurance companies. The goals of this platform will be to inform about the extent of this issue, to identity and promote leaders that will convey the aims of this initiative to regional and national healthcare authorities, to present solutions and to collaborate in their implementation, and finally to assess/control the actions taken.

Está muy bien documentado en la literatura médica que la desnutrición es un problema común en todos los niveles de atención sanitaria, desde atención primaria a especializada y en centros de atención geriátrica. Este problema no se limita a países con pocos recursos económicoso con limitado desarrollo social y económico. Tambiénes un problema universal en Europa. La desnutrición aumenta las cifras de morbilidad, mortalidad, ingresos hospitalarios y duración de la estancia. Estas cifras más elevadas suponen lógicamente un aumento deluso de recursos sanitarios. A pesar de esto, el problema de la desnutrición a menudo puede pasar desapercibido y el paciente no recibir el tratamiento necesario. Este problema requiere la cooperación de múltiples agentes tales como los Gobiernos de los Estados, los profesionales de la salud y los mismos ciudadanos. El VIII Foro de Debate concluye con la necesidad de establecer un claro plan de actuación (a semejanza de la European Alliance for Health Nutrition) y la creación de una plataforma (coalición) que reúna las voces de asociaciones de profesionales sanitarios, instituciones, colegios profesionales, asociaciones de pacientes, industria y entidades aseguradoras. Los fines de esta plataforma consistirán en informar de la extensión del problema, identificar y potenciar líderes que transmitan los fines de esta iniciativa ante las autoridades autonómicas y nacionales, propuesta de soluciones y colaboración en su puesta en marcha y finalmente, evaluación/control de las acciones desarrolladas (AU)

Vitamin D deficiency in Spain: a population-based cohort study.

BACKGROUND: Vitamin D deficiency is common worldwide. No homogenous reference values have yet been established and no studies of values have been conducted in Spain involving a large number of participants. OBJECTIVE: To study the population concentrations of vitamin D in a representative sample of the Spanish population. SUBJECTS/METHODS: The study involved two cohorts from Spain, the Asturias study and the Pizarra study, which are two prospective, population-based studies involving 2260 participants. In 1262 subjects (age: 20-83 years) we studied 25-hydroxyvitamin D, intact parathyroid hormone (iPTH), calcium, phosphorus and creatinine. RESULTS: The median population values of 25-hydroxyvitamin D and iPTH were 22.46 ng/ml and 42.29 pg/ml, respectively. The values of 25-hydroxyvitamin D were significantly higher in summer and correlated with age (ß = -0.05 ± 0.01, P < 0.0001), creatinine (ß = 6.42 ± 1.17, P < 0.0001) and iPTH (-0.07 ± 0.01, P < 0.0001), but not with calcium, phosphorus or sex. The increase in iPTH with age was seen whatever the values of 25-hydroxyvitamin D, and was greater in the older persons. The concentration of iPTH rose continuously with effect from 25-hydroxyvitamin D values below ≈30 ng/ml. Values above ≈35 ng/ml were associated with a significantly lower concentration of iPTH. CONCLUSIONS: One-third (33.9%) of the Spanish population may be at risk for Vitamin D deficiency. The 25-hydroxyvitamin D values above 30 ng/ml can safely discard 'hyper PTH'. The increase in iPTH concentration is greater in older persons for similar values of 25-hydroxyvitamin D.

Gastric cancer is a frequent cause of cancer-related mortality in the world. Surgery is the only potentially curative therapy, although the adverse effects of surgery are common and considerable. Common variable immunodeficiency is in many cases cause of gastrointestinal system problems such as chronic diarrhea caused by infestation with giardia lamblia, nodular lymphoid hiperplasia ad loss of villi leading frequently to malapsortion and malnutrition. Nutritional deficiencies due to malapsorption (postgastrectomy and secondary to loss of villi, giardiasis and common variable inmunodeficiency) are common. We present the case of a patient with gastric cancer who underwent a gastrectomy with common variable hipogammaglobulinemia and chronic infestation by giardia lamblia, with serious diarrhea resistant to treatment and malabsorption.

Se presenta el caso de una mujer de 35 años con síndrome de intestino corto severo secundario a isquemia intestinal aguda en la edad adulta, que presenta a los 5 años de evolución episodios de mareos con inestabilidad en la marcha y pérdida de fuerza en las manos, llegándose al diagnóstico de acidosis D-láctica. La acidosis D-láctica representa una complicación infrecuente, pero importante por su sintomatología, de este síndrome. Se debe a un cambio en la flora intestinal debido a un sobre crecimiento de bacterias acidolácticas, que producen D-lactato. Debe sospecharse en aquellos casos de acidosis sin causa aparente y manifestaciones neurológicas sin focalidad en pacientes con síndrome de intestino corto o intervenidos de by-pass yeyuno-ileal. El tratamiento apropiado resuelve con frecuencia los síntomas neurológicos y previene o reduce las recurrencias (AU)

The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagnosis was D-lactic acidosis. D-lactic acidosisis a rare complication, but important for their symptoms, of this syndrome. It is due to a change in intestinal flora secondary to an overgrowth of lactic acid bacteria that produce D-lactate. D-lactic acidosis should be looked for in cases of metabolic acidosis in which the identity of acidosis is not apparent, neurological manifestations without focality and the patient has short bowel syndrome or patients who have had jejunoileal bypass surgery. Appropiate treatment usually results in resolution of neurologic symptoms and prevents or reduces further recurrences (AU)

[Costs versus benefits of oral nutritional supplements]. / Costes frente a beneficios de los suplementos nutricionales orales.

Health economics pretends to assign resources that are short in essence and that may be used for other purposes. Health costs analysis pretends to compare the pros and cons of several options among which an election can be made in order to obtain greater benefits with lower costs. The current legislation on prescription of enteral nutrition entails confusing definitions about the administration route and the requirements of home-based enteral nutrition, without a specific regulation comprising the prescription of oral supplements (OS). From the year 2000 to 2007, the consumption of homebased enteral nutrition in Andalusia increased considerably; the costs generated being multiplied by 37. Although the number of persons that daily consumed supplements was higher than the number of diets through nasogastric tube (DT) during the years evaluated, the costs derived from OS surpassed those of DT from the year 2005 due to the combination of two factors: a progressive increase in the number of persons to whom supplements were prescribed, and on the other hand the incorporation of more expensive specific formulations. The use of oral supplements seems to be cost/effective in hospitalized surgical patients (during the pre- and postsurgical period) and possibly in hospitalized malnourished elderly, especially after performing a hyponutrition screening. Although they may be effective, under other circumstances, such as ambulatory patients, studies with an adequate methodology are necessary in order to adopt clinical decisions based on evidence and cost analysis.

Comparativa de las Ingestas Dietéticas de Referencia (IDR) de los diferentes países de la Unión Europea, de Estados Unidos (EEUU) y de la Organización Mundial de la Salud (OMS) / Comparison of dietary reference intakes (DRI) between different countries of the European Union, The United States and the world health organization

Antecedentes: En España, existen varios organismos y sociedades científicas que han editado sus propios de valores de referencia sobre la ingesta recomendada de nutrientes, que no siempre coinciden en los contenidos y formas presentadas. Objetivo: Revisar los conceptos, datos y la metodología que han seguido otros países o grupos de países para obtener y documentar sus propios Valores de Referencia, con objeto de ofrecer una información básica que facilite el establecimiento de los valores de referencia que mejor puedan adaptarse a la población española, en base a la mejor evidencia científica disponible en la actualidad. Ámbito: Revisión de la información disponible en los distintos países (o grupos de países) de la Unión Europea, Estados Unidos y la Organización Mundial de la Salud. Los datos estudiados corresponden a poblaciones sanas. Conclusiones: Las ingestas de referencia difieren notablemente entre los distintos países estudiados en cuanto a grupos de población, tipo de nutrientes incluidos, metodología y periodicidad de las revisiones publicadas. Sin embargo, la mayoría definen de manera semejante los conceptos más importantes, aunque tengan distintas denominaciones en cada país. Por otro lado, en la mayoría de los casos estudiados existe un único organismo científico encargado de la publicación y actualización de los valores de ingestas dietéticas de referencia, no siendo así en España. En este contexto, parece conveniente alcanzar un acuerdo entre todos los organismos y sociedades científicas españolas implicadas en esta tarea, con objeto de establecer unos valores de referencia únicos para todo el país, con el consenso de todos (AU)

Background: In Spain, there are some organizations and scientific societies that have edited reference values of recommended nutrient intake, but whose data does not always agree in terms of format and content. Aims: To review the definitions, data and methodology that other countries or groups of countries have followed to obtain and document their own reference values in order to offer basic information to facilitate the establishment of the best reference values for the Spanish population. Field: Review of the available information in different countries (or groups of countries) from the European Union, the United States and World Health Organization. The analysed data concerned to healthy populations. Conclusions: Reference intakes differ among the examined countries according to population groups, included nutrients, methodology and frequency of published reviews. However, most of the countries define major concepts in the same way, although with different names in each country. On the other hand, most of the studied cases represent only a scientific organization in charge of the publication and update of the values of dietary reference intakes, but not in Spain. In that context, it looks convenient to reach a consensus among all Spanish organizations and scientific societies that are involved in this task, in order to establish an acceptable reference values (AU)

Costes frente a beneficios de los suplementos nutricionales orales / Costs versus benefits of oral nutritional supplements

La economía de la salud pretende asignar unos recursos que son, por definición, escasos y que, a su vez, pueden ser invertidos para otros usos. El análisis de costes en salud pretende comparar los pro y los contras de diversas opciones entre las que se puede elegir, para obtener los mayores beneficios con menores costes. La legislación actual sobre prescripción de nutrición enteral recoge definiciones confusas acerca de la vía de administración y los requerimientos en la nutrición enteral domiciliaria, no existiendo una normativa específica que recoja la prescripción de suplementos orales (SO). Desde el año 2000 a 2007, el consumo de nutrición enteral domiciliaria en Andalucía aumentó notablemente, multiplicándose los costes generados por 37. Aunque el número de personas que consumieron diariamente suplementos fue superior al de las dietas por sonda (DS) durante todos los años evaluados, los costes derivados de los SO superaron a los de las DS a partir del año 2005, debido a la combinación de dos factores: incremento progresivo del número de personas a las que se les prescribieron suplementos y, por otro lado, por la incorporación de formulaciones específicas más caras. El empleo de suplementos orales parece ser coste/efectivo en pacientes quirúrgicos hospitalizados (en el pre y post operatorio) y, posiblemente, en ancianos malnutridos hospitalizados, especialmente tras realización de cribado de desnutrición. Aunque podrían ser eficaces, en otras circunstancias, como en pacientes ambulatorios, son necesarios más trabajos con metodología adecuada, para poder realizar decisiones clínicas basadas en la evidencia y en los análisis de costes (AU)
