Abstract The need to promote the right to nutritional care, to fight against malnutrition and to advance in education and research in clinical nutrition has led all the FELANPE's societies to sign on May 3rd, during the 33rd Congress of the Colombian Clinical Nutrition Association (ACNC) in the city of Cartagena, the International Declaration on the Right to Nutritional Care and the Fight against Malnutrition, "Declaration of Cartagena". The Declaration provides a coherent framework of 13 principles which can serve as a guide for societies, schools and associations affiliated to FELANPE in the development of action plans. In addition, it will serve as an instrument to promote, through governments, the formulation of policies and legislation in the field of clinical nutrition. We believe that the general framework of principles proposed by the Declaration can contribute to raise awareness about the magnitude of this problem and to promote cooperation networks among Latin-American countries. Although this Declaration does not have a binding legal effect, it has an undeniable moral strength and it can provide practical guidance to States. An implementation program will allow developing a toolkit to transform principles into actions.

Resumen Frente a la necesidad de promover el derecho al cuidado nutricional, de luchar contra la malnutrición y de avanzar en temas de educación e investigación en nutrición clínica, las sociedades que constituyen la FELANPE firmaron la Declaración Internacional sobre el Derecho al Cuidado Nutricional y la Lucha contra la Malnutrición, "Declaración de Cartagena", el 3 de mayo del presente año en la ciudad de Cartagena, en el marco del 33º Congreso de la Asociación Colombiana de Nutrición Clínica. La Declaración proporciona un marco coherente de 13 principios, los cuales podrán servir de guía a las sociedades afiliadas a la FELANPE en el desarrollo de los planes de acción. Además, servirá como un instrumento para que promuevan, a través de los gobiernos, la formulación de políticas y legislaciones en el campo de la nutrición clínica. Consideramos que el marco general de principios propuesto por la Declaración puede contribuir a crear conciencia acerca de la magnitud de este problema y a forjar redes de cooperación entre los países de la región. Aunque esta Declaración no tiene un efecto jurídico vinculante (obligatorio), tiene una fuerza moral innegable y puede proporcionar orientación práctica a los estados. Un plan de implementación permitirá desarrollar la caja de herramientas necesaria para transformar los principios en acciones.

O objetivo do presente trabalho foi testar a composição química do líquido hidático bovino (BHCF) obtido de cistos hidáticos férteis (FC) e não férteis (NFC). Oito lotes de FC e 5 de NFC foram preparados e testados quanto à composição química, proteínas totais, proteínas derivadas do hospedeiro, conteúdo de carbohidratos e lipídeos. Não foram observadas diferenças entre os dois primeiros parâmetros sendo que o conteúdo de carbohidratos e lipídeos foi maior nos lotes FC do que nos NFC. Por SDS-PAGE foram observadas bandas de 38 e 116 kD somente nos BHCF do FC. Foram preparados dois «pools» de BHCF, um de FC (PFC) e outro de NFC (PNFC). Os padrões de reconhecimento dos antígenos foram analisados por imunoblot. As condições físico-químicas para adsorção dos antígenos na superfície das placas de poliestireno (ELISA plates) foram otimizadas. O valor de diagnóstico de ambos tipos de BHCF bem como a importância diagnóstica da oxidação das moléculas de carbohidratos com periodato foram analisadas por ELISA usando 42 amostras de soro de pacientes com hidatidose, 41 de pacientes com outras doenças e 15 de doadores aparentemente saudáveis. A reatividade de todos soros contra antígenos nativos foi analisada com e sem fosforilcolina livre. A melhor eficiência diagnóstica foi observada usando BHCF de PFC tratado com periodato usando tampão glicina com forte força iônica para sensibilizar as placas de ELISA.

The aim of this work was to assess the influence in the diagnostic value for human hydatid disease of the composition of bovine hydatid cyst fluid (BHCF) obtained from fertile (FC) and non-fertile cysts (NFC). Eight batches from FC and 5 from NFC were prepared and analysed with respect to chemical composition: total protein, host-derived protein, carbohydrate and lipid contents. No differences were observed in the first two parameters but carbohydrate and lipid contents were shown to be higher in batches from FC than in those from NFC. Bands of 38 and 116 kD in SDS-PAGE profiles were observed to be present in BHCF from FC only. Two pools were prepared from BHCF batches obtained from FC (PFC) and NFC (PNFC), respectively. Antigen recognition patterns were analysed by immunoblot. Physicochemical conditions for adsorption of antigens to the polystyrene surface (ELISA plates) were optimized. The diagnostic value of both types of BHCF as well as the diagnostic relevance of oxidation of their carbohydrate moieties with periodate were assessed by ELISA using 42 serum samples from hydatid patients, 41 from patients with other disorders, and 15 from healthy donors. Reactivity of all sera against native antigen were tested with and without free phosphorylcholine. The best diagnostic efficiency was observed using BHCF from periodate-treated PFC using glycine buffer with strong ionic strength to coat ELISA plates.
