Serum IL-15 and IL-15Rα levels are decreased in lean and obese physically active humans.

Circulating IL-15 presence is required to stimulate anti-adipogenic effects of the IL-15/IL-15Rα axis in adipose tissue. Although exercise increases blood IL-15 expression post-exercise, it remains inconclusive whether physical activity can alter the baseline concentrations of this cytokine. The aim of this study was to determine whether physical activity regulates circulating IL-15 and IL-15Rα in lean and obese individuals. Two hundred and seventy-six participants were divided into five groups according to physical activity (PA), body mass and type 2 diabetes mellitus (T2DM) diagnosis: (a) lean PA (N = 25); (b) lean non-PA (N = 28); (c) obese PA (N = 64); (d) obese non-PA (N = 79); and (e) obese non-PA with T2DM (N = 80). Serum IL-15 and IL-15Rα, blood glucose/lipid profile and body composition were measured. Serum IL-15 and IL-15Rα decreased in PA participants compared to non-PA (P < .05), while IL-15 and IL-15Rα increased in obese with T2DM compared to obese without T2DM (P < .05). No differences were observed between lean non-PA and obese PA. Serum IL-15Rα was associated with fasting glucose (R2 = .063), insulin (R2 = .082), HbA1c (R2 = .108), and HOMA (R2 = .057) in obese participants. Circulating IL-15 and IL-15Rα are reduced in lean and obese participants who perform physical activity regularly (≥180 min/week), suggesting a regulative role of physical activity on the circulating concentrations of IL-15 and IL-15Rα at baseline. Moreover, the relationship observed between IL-15Rα and glucose profile may indicate a role of the alpha receptor in glucose metabolism.

[Prevalence of obesity among children in Ceuta. PONCE study 2005]. / Prevalencia de obesidad infantil en Ceuta. Estudio PONCE 2005.

The continuous increasing of overweight and obesity, among children and adolescents, constitutes an important public health problem. It is necessary to know and quantify this problem in order to delimit its magnitude and to identify the main risk groups. The enKid study (1998-2000) has estimated an obesity prevalence in Spain of 13,9% within the population group aged 2-22 years. Up to now, there was no data available about the city of Ceuta. In this study, it has been estimated an obesity prevalence of 8,75% among the Ceuta population group aged 6-13 years.

[Bilateral corneal ulceration as a result of caloric-protein malnutrition and vitamin A deficit in a patient with chronic alcoholism, chronic pancreatitis and cholecystostomy]. / Ulcera corneal bilateral como consecuencia de malnutrición calórico- protéica y déficit de vitamina A en un paciente con alcoholismo crónico, pancreatitis crónica y colecistostomía.

Since the discovery of vitamins, there has been an increasing interest at relating vitamins with particular diseases. In particular, for vitamin A its singular importance has been determined in multiple vital functions, and its relationship with diseases, both in deficit and in excess, is nowadays completely demonstrated. In developed countries, vitamin deficiency-related diseases have been greatly reduced; however, in some patients with particular features they must be kept in mind. This is the case of a 45 year-old man, with a history of chronic alcoholism, non insulin-dependent diabetes meIlitus and cholecystectomy with a high biliary drainage secondary to emphysematous cholecystitis and perivesicular abscess. He complains of bilateral ocular pain, photophobia, and decreased visual acuity besides a history of pasty, sticky and foul-smelling feces. He is admitted in the Ophthalmology Department and bilateral corneal ulceration is diagnosed. A consultation to the Nutrition Department is made because of cachexia. Severe caloric and mil protein hyponutrition is observed with a BMI of 18.2 and a 23% weight loss for the last 6 months, fat-soluble vitamins (A, D and E) deficit, mild fat malabsorption, and macrocytic and hypochromic anemia. The patient's diet is supplemented with a special hyperproteinic and hypercaloric diet for diabetics, deficient vitamins and pancreatic enzymes to improve absorption are administered, and glycemia is controlled with insulin. Four months later, the patient is assessed and has a BMI of 20, anemia has resolved and from an ophthalmologic viewpoint the course is favorable, the ulcers improve and visual acuity is almost completely recovered. In chronic alcoholic patients with a low dietary intake and clinical complications with nutritional repercussions (pancreatitis that produces malabsorption or cholecystectomy with biliary percutaneous drainage) we should not forget that micronutrients deficits may explain the etiology of other associated diseases, in the present case corneal ulceration.

[Assessment of home parenteral nutrition programme in terminal oncological patients]. / Evaluación de un programa de nutrición parenteral domiciliaria en pacientes oncológicos terminales.

BACKGROUND AND GOALS: The assessment of the acceptance of the diets served at the hospital allows the introduction of adjustments to improve the quality of the service provided to hospitalized patients by preventing the complications derived from incorrect nutrition and enhancing their stay in hospital. The goal of the present study was to analyze the acceptance of the menus offered by the Hospital's catering service. SCOPE OF THE STUDY: Menus provided by the catering service of the "Sant Joan de Reus" University Hospital. MATERIAL AND METHODS: A total of 160 tray meals consumed were assessed, all chosen at random and corresponding to standard diets and special diets, including puréed food. The assessment was made by two dieticians in the hospital's kitchens. A visual scale was used with the following scores: 0 for a full plate, 1 for residual food amounting to over 75%, 2 from 50% to 75%, 3 more than or equal to 25% and 4 for empty plates. RESULTS: A total of 68 trays containing a standard diet were analyzed, together with 34 containing special diets and 41 with puréed food. The remains on 36 different courses from the standard diet were analyzed. The mean acceptance score was 3.01 +/- 1.30 in the case of the first courses, 3.24 +/- 1.11 in second courses and 3.53 +/- 0.96 for the desserts. As for special diets, a total of 27 different courses were analyzed. The mean acceptance score was 2.87 +/- 1.38 in the case of the first courses, 3.02 +/- 1.27 in second courses and 3.49 +/- 1.22 for the desserts. The first courses of puréed diets received the worst score of all the dishes served, although the overall mean score was good, 2.76 +/- 1.5. CONCLUSIONS: In general, a good level of acceptance has been observed for the set meals served in the hospital. Knowing which courses have lower acceptance scores allows changes to be proposed to the hospital menus, with their replacement by others with foreseeably better acceptance.

Evaluación de un programa de nutrición parenteral domiciliaria en pacientes oncológicos terminales / Assessment of home parenteral nutrition programme in terminal oncological patients

A pesar de que el cáncer constituye en la mayoría de las series publicadas la patología de base más frecuente para la indicación de Nutrición Parenteral Domiciliaria (NPD), su utilización en pacientes terminales sigue siendo objeto de controversias. Nuestro objetivo ha sido revisar la evolución de los pacientes con cáncer tratados con NPD procedentes del Hospital La Paz con el fin de estudiar su indicación, evolución y complicaciones. Revisamos un total de 9 pacientes oncológicos terminales que habían sido tratados con NPD entre enero de 2000 y diciembre del 2002. Con una edad media de 60,4 años (44-81), el cáncer de base más frecuente era el adenocarcinoma gástrico (44%). La obstrucción intestinal en el contexto de una carcinomatosis peritoneal fue el motivo de indicación en el 89% de los casos y la mediana de supervivencia de 71 días (23-131). La infección del catéter representó la complicación más frecuente con 1,4 episodios/paciente. La existencia de un Equipo de Soporte Domiciliario facilitó el seguimiento de los pacientes, estimándose la NPD como tratamiento proporcionado en el 67% de los casos. El 56% de los pacientes no estaban suficientemente informados de su enfermedad de base. Aunque la NPD es un recurso terapéutico más, del que podemos disponer en algunos pacientes oncológicos terminales, debemos afinar la indicación lo más posible teniendo en cuenta una serie de "garantías sistemáticas" que incluyen el cumplimiento de los criterios clínicos pertinentes, el consentimiento informado y la colegiación en la decisión de todos los profesionales implicados en el seguimiento del paciente. Proponemos un algoritmo de actuación para ayudar a mejorar el proceso de toma de decisiones en estos pacientes (AU)

[Complications of enteral nutrition at home. Results of a multicentre trial]. / Complicaciones de la nutrición enteral domiciliaria. Resultados de un estudio multicéntrico.

AIM: In spite of the increasing number of home enteral nutrition (HEN) patients, only few articles had reported the frequency of complications related to this treatment. Our multicentric study analyzes the HEN complications in relation to access device and time of treatment. METHOD: 92 HEN patients from 8 hospitals were randomly selected. Patients were distributed in relation to the time of treatment and access device (nasogastric tube and percutaneous or surgical gastrostomies). After an educational program, they were filled in an initial questionnaire and repeated it the days 15 and 30. They received a mean of 1650 Kcal of enteral solution. A total of 2760 HEN prospective days were analyzed. RESULTS: In prospective study 42% of patients had some complication (112 episodes). The most frequent were gastrointestinal (55%) and mechanical (29%); 0.16 complications of patient-year were registered. The most common complications were: extraction (15%), constipation (13%), vomiting (12%) and diarrhoea (10%). The gastrostomy group had more gastrointestinal complications. In retrospective evaluation, percutaneous gastrostomy group had the lowest ratio of complications and nasogastric tube group required more tube replacements (4 vs 2) and had 1.96 episodes/patient (percutaneous group 1.85 and surgical gastrostomy 3.1 episodes/patient). CONCLUSION: HEN is safe with low incidence of complications. An adequate educational program is very important and we expect, in the future, to establish an proper National Home Care System.

Complicaciones de la nutrición enteral domiciliaria. Resultados de un estudio multicéntrico / Complications of enteral nutrition at home. Results of a multi-centre trial

Objetivo: A pesar del número creciente de nutrición enteral domiciliaria (NED), sólo algunos artículos recogen la frecuencia de sus complicaciones. Este estudio multicéntrico analiza estas complicaciones en relación a la vía de acceso y la duración del soporte nutricional. Método: Seleccionamos aleatoriamente 92 pacientes con NED de 8 hospitales y se distribuyeron en relación a la duración del soporte y a la vía de acceso: sonda nasogástrica (SNG) y gastrostomías percutánea o quirúrgica. Tras un programa educativo, los pacientes completaron un cuestionario inicial que se repitió en los días 15 y 30.Recibieron una media de 1.650 kcal de fórmula enteral. Se analizaron un total de 2.760 días prospectivos de NED. Resultados: En la fase prospectiva, el 42 por ciento de los pacientes tuvo alguna complicación (112 episodios). Los más frecuentes fueron digestivos (55 por ciento) y mecánicos (29 por ciento); se registraron 0,16 complicaciones por paciente-año. Las complicaciones más comunes fueron: extracción (15 por ciento), estreñimiento (13 por ciento), vómitos (12 por ciento) y diarrea (10 por ciento). El grupo de gastrostomía tuvo más complicaciones digestivas. En el análisis retrospectivo, el grupo de gastrostomía percutánea tuvo menos complicaciones y el de SNG requirió más recambios de sondas (4 frente a 2) y tuvieron 1,96 complicaciones/paciente (grupo de gastrostomía percutánea 1,85 y quirúrgica 3,1). Conclusión: La NED es segura y presenta una baja incidencia de complicaciones. Un programa educativo adecuado es muy útil y esperamos, en el futuro, contribuir a un mejor sistema de atención domiciliaria (AU)

[Nutritional evaluation in patients with total gastrectomy]. / Evaluación nutricional en pacientes con gastrectomía total.

Gastric cancer continues to be the second cause of cancer-related mortality in the world. Surgery is the only potentially curative therapy, although the adverse effects of surgery are considerable and include digestive symptoms, loss of appetite and malnutrition. Our study included 45 patients subjected to gastrectomy who were under treatment at our unit during 2000. The data given here refer to their first visit following surgery. The most frequent complications were diarrhoea (31%), pain (29%) and early dumping (24%). Other complications found were late dumping, nausea/vomiting and dysphagia. Anorexia appeared in 49% and 29% presented a negative attitude towards food. These complications give rise to insufficient food intake, leading to malnutrition, mainly marasmic in nature. Only 7% of the patients were normonourished, with 86% presenting slight or moderate malnutrition and 7% severe malnutrition. The mean Body Mass Index (BMI) of these patients was 20 +/- 3 kg/m2. The most frequent analytical alterations were anaemia with ferropenia and b12 deficit, and a reduction in the levels of zinc and retinol transporting protein. Many patients had impaired quality of life; 43% did not leave home and only 13% were able to work. Three groups were established depending on the time that had passed since the gastrectomy was performed before the first nutritional assessment (less than 3 months, from three months to a year, and over one year), without significant differences being found in any of the parameters studied. In this article we include recommendations for the nutritional handling and treatment of patients following gastrectomy.

[Changes in carbohydrate metabolism in the HIV/AIDS patient]. / Alteraciones del metabolismo hidrocarbonado en el paciente VIH/SIDA.

Over the last few years, there has been a considerable reduction in the mortality and morbidity associated with HIV patients, due to the use of protease inhibitors which have led to a true revolution in the treatment of this infection. A new problem has arisen with the increased life expectancy: the onset of a plurimetabolic syndrome characterized by hypertriglyceridaemia, hypercholesterolaemia and hyperglycaemia; in addition to anomalies in composition and distribution of body fat (central obesity and loss of peripheral fat) due to the associated lipodystrophy. As a result of the metabolic alterations, there is an increase in the risk of cardiovascular disease. Hyperglycaemia is the result of insulin resistance and is detected in between 13.6% and 46% of patients, possibly leading to type 2 diabetes (diagnosed in between 2.4% and 7% of the patients). These alterations have been documented as potentially related with the use of protease inhibitors and other drugs used in the handling of HIV patients. The appropriate treatment of altered metabolism of carbohydrate requires: 1) a customized dietary approach depending on individual BMI and lipid alterations; 2) a physical exercise programme; 3) the use of insulin sensitization drugs: metformin and thiazolidinediones and, where the therapeutic goals are not achieved or there is a contraindication for oral hypoglycaemic drugs; 4) insulin therapy with regimens similar to other diabetic patients.

[Fiber and enteral nutrition]. / Fibra y nutrición enteral.

Dietary fibre is a mixture of various substances and is essential for maintaining appropriate intestinal functionality and it is currently considered to be a necessary part of a healthy diet. Current recommendations for fibre consumption by adults range from 20 to 35 g/day. Enteral nutrition is an emerging therapeutic variation in both hospital and domestic settings. To a great extent, this development has been made possible thanks to the design of new formulas that adapt better and better to the clinicla conditions or our patients. The type of fibre used in these preparations varies greatly. Some have only one source of fibre while others use differnet combinations. There are currently 32 formulas available on the Spanish market, without counting the modules or specific preparations of individual types of fibre. Despite the enormous advances in the knowledge of the beneficial effects of fibre, the fact of the matter is that enteral nutrition that we routinely prescribe in normal clinical practice does not contain fibre. The are several explanations for this, perhaps the most plausible is that these formulas may lead to problems in their administration and tolerance. It is necessary to choose the correct calibre of catheter and define the best infusion method and timing. Another difficulty may be the gastrointestinal tolerance of the formulas containing fibre. No large-scale problems of intolerance have however been described in healthy volunteers nor in patients with acute or chronic pathologies, although it is of fundamental importance to monitor the rhythm of depositions in all patients with enteral nutrition (EN) and ensure proper intake of liquids, which would also be useful to prevent occlusion of the catheter. The theoretical benefits of EN with fibre with a view to maintaining or improving normal intestinal structure and function are very varied. Nonetheless, it has noit yet been possible to prove many of these effects in controlled clinical trials. At the present time, there are sufficient reasons of a physiological nature for using EN with fibre in many patients, particularly in those predisposed to constipation or suffering from diarrhoea, in those requiring long-term EN and in some intestinal pathologies. In the near future, fibre can be expected to form part of EN as standard component and we should define its optimal composition for different pathologies. In the meantime, we need to continue working intensely in this highly promising area of knowledge.

[Home enteral nutrition. Annual report 1999. NADYA-SENPE Group]. / Nutrición enteral domiciliaria. Informe anual 1999. Grupo NADYA-SENPE.

GOAL: During 1999, as in previous years, the NADYA-SENPE Group has maintained an annual register of patients with Artificial Nutrition at Home in order to keep up to date our available knowledge of this therapy. The present paper analyzes the results of the sixth National Register of patients under treatment with Enteral Nutrition at Home corresponding to 1999, produced with the co-operation of twenty-three centres in the Spanish national health network. MATERIAL AND METHODS: The data were collected through a closed questionnaire included on our web site (www.nadya-senpe.com). Apart from epidemiological information, the form includes the indication that led to the prescription of nutrition, nutritional treatment, access path, complications and admissions to hospital, follow-up of the treatment, patients' quality of life and progress. All of the data are processed by the co-ordinating team. The Nutrition Unit at La Paz Teaching Hospital in Madrid has acted as the group co-ordinator. RESULTS: During 1999, a total of 2,262 patients at the twenty-three collaborating centres followed treatment with Home Enteral Nutrition (NED in its Spanish acronym). The mean age was 63.6 (19.67 years (males: 57.6%; females: 42.3%). The mean time with nutritional treatment is 5.89 (4.25 months. The neurological alterations (37.5%) and neoplasias (36.8%) were the most frequent indications for NED. Most patients used oral administration (50.7%), the use of artificial routes is less frequent, with 5NG being used on 27.9% and PEG on 12.7%. The polymeric formulas are the ones most commonly used (87.7%). The number of complications recorded amounted to 1,403 episodes, representing 0.62 complications per patient per year, of which 40.8% were gastro-intestinal (0.26 complications per patient per year) and 18.7% were mechanical complications, with only 9 recorded cases of bronchoaspiration. It was necessary to admit patients to hospital on 836 occasions (0.38 admissions per patient), albeit generally for causes not associated with nutrition (86.1%). At year-end, 51.4% of patients continued to receive nutritional support. CONCLUSIONS: Enteral nutrition at home is a safe technique whose use is growing in Spain. It requires the existence of appropriately equipped nutrition teams as well as the collaboration of the Primary Health Care services and the suitable training of patients and relatives. It is essential to progress more deeply into the development and application of clinical routes that provide a clear and concise methodology covering all nutrition-related aspects. In itself, nutrition is a therapeutic alternative regardless of whether access is obtained through a natural or an artificial route. It is necessary for the persons responsible for health-care administration to realize that the appropriate nutrition of patients leads to an improvement in their general health, a shorter course for their illness and, therefore, a reduction in costs.

Consenso sobre diagnóstico y tratamiento de las alteraciones del metabolismo hidrocarbonado en la fibrosis quística / Consensus on the diagnosis and management of cystic fibrosis related diabetes

La alteración del metabolismo hidrocarbonado es una complicación frecuente de la fibrosis quística. La diabetes relacionada con fibrosis quística (DRFQ) se debe a una disminución en la secreción de la insulina secundaria a la insuficiencia pancreática. Los pacientes con fibrosis quística y diabetes presentan mayor morbilidad y mortalidad y el mismo riesgo de las complicaciones crónicas de la diabetes que los pacientes con diabetes tipo 1o 2.El diagnóstico precoz y el tratamiento adecuado de la diabetes de estos pacientes es imprescindible. En mayo de 2000tuvo lugar en Madrid una conferencia de consenso sobre DRFQ para definir las pautas para su diagnóstico y tratamiento (AU)

[Consensus on the diagnosis and management of changes in carbohydrate metabolism in cystic fibrosis]. / Consenso sobre diagnóstico y tratamiento de las alteraciones del metabolismo hidrocarbonado en la fibrosis quística.

Abnormal glucose tolerance and diabetes mellitus are a common complication of cystic fibrosis (CF). Cystic fibrosis related diabetes (CFRD) is due to decreased insulin secretion, secondary to pancreatic insufficiency. Patients with CFRD have increased morbidity and mortality and are subject to the same microvascular complications as patients with other types of diabetes. Prompt diagnosis and aggressive management of CFRD is important.A consensus conference on CFRD was held in Madrid in May 2000to define the current standards for the diagnosis and management of this disease in Spain.

[Evaluation of the cost of home enteral nutrition in relation to different access routes]. / Evaluación del coste de la nutrición enteral domiciliaria con relación a diferentes vías de acceso.

UNLABELLED: When home enteral nutrition is needed, there is still, despite the undisputed increase in the quality of life that can be achieved with a Percutaneous Endoscopic Gastrostomy (PEG), a reservation in its use because this technique and its maintenance is considered to be very costly. We aim to assess the true cost of home enteral nutrition using the oral route, a nasogastric tube, and PEG. PATIENTS AND METHODS: The data of 65 patients who required home enteral nutrition during 1996, were analyzed retrospectively. The access route was a nasogastric tube in 20 cases, 18 patients had PEG, and 27 candidates used an oral route. The average age was 56 years. 50% were men and 50% were women. The most common diagnoses that led to the indication were oropharyngeal-maxillofacial neoplasms and neurological disorders. In all cases the material and formula used was assessed, as were the associated complications and the cost of the at home enteral nutrition. RESULTS: The average duration of the treatment was 175 +/- 128 days, and this was similar in all three groups. The average formula/day cost was slightly higher in the patients using the oral access route. The average total day cost and the average material/day cost was slightly higher in patients with a PEG. Patients with a PEG presented fewer complications than those with a nasogastric tube. The cost derived from possible complications must be higher in the nasogastric tube group, especially considering the repeated tube changes due to obstruction or loss. CONCLUSIONS: The cost of home enteral nutrition is slightly lower if one uses a nasogastric tube. The greater incidence of complications that were mild but required a tube change, in this case a nasogastric tube, suggests higher indirect costs. The oral route is associated with the need for special formulae that are more expensive.
