ABSTRACT
Introduction: Patients who are at risk of malnutrition are potential candidates for the use of enteral nutritional therapy (ENT), since it allows a more effective control of the patient's nutrition. When oral food intake is impossible or insufficient, enteral nutrition is the most appropriate physiological option aiming at the maintenance of gastrointestinal trophism. Studies show us that the protein-caloric needs of the hospitalized patients are seldom reached in the feeding tube supply, staying routinely between 70% and 80% of their needs. Methods: A descriptive study was conducted based on secondary data collected by the Multidisciplinary Team of Nutritional Therapy of a university hospital in Brazil to compare the caloric intake received by the hospitalized patients when in enteral nutritional therapy with their real needs. Results: A total of 43 adult inpatients who were in exclusive enteral nutrition were assessed. It was observed that the mean caloric intake received by the patients was 1,767±271kcal/day, reaching 94% of the estimated caloric needs, which were 321kcal/day. In relation to the nutritional status of the analyzed patients, it was found that 38% were at nutritional risk. Conclusion: The creation of protocols of nutritional support is of great importance to guide professionals in the prescription of ENT, aiming to improve the nutritional intake offered to hospitalized patients (AU)

CONTEXT: Intestinal metaplasia of the stomach is a lesion in which metaplasia of gastric epithelial cells occurs for an intestinal phenotype. Gastric intestinal metaplasia is a lesion associated with an increase in the risk of gastric carcinoma development. Epidemiologic studies indicate a relation between dietary habits and stomach cancer development, some habits increasing the risk for it, and others have a protective effect, suggesting that antioxidants, such as vitamins A, C, and E, decrease the risk of this type of cancer. The relationship of these alimentary factors and intestinal metaplasia is unknown. METHODS: It is a case-control, observational study in which 320 patients with functional dyspepsia, divided in two groups, were assessed. The case I group (individuals with intestinal metaplasia) had their dietary pattern compared to that of the control group, constituted of individuals similar to those in the case group but without intestinal metaplasia, through a food frequency questionnaire. RESULTS: The analysis of the dietary pattern of functional dyspeptic patients with intestinal metaplasia, and its comparison with those without intestinal metaplasia, showed a higher frequency of canned and smoked foods consumption in the first group and, on the other hand, a higher consumption of fruits and vegetables in patients without intestinal metaplasia. No effect of salt consumption was detected. CONCLUSIONS: The results obtained in this study suggest changes in the diet, with a decrease in the consumption of smoked and canned foods, and an increase in the consumption of fruits and vegetables, can lead to a diminution of gastric intestinal metaplasia cases.
CONTEXTO: A metaplasia intestinal do estômago é uma lesão onde ocorre a metaplasia das células epiteliais gástricas para um fenótipo intestinal. A metaplasia intestinal gástrica é considerada uma lesão associada ao aumento do risco de desenvolvimento de carcinoma gástrico. Estudos epidemiológicos indicam uma relação entre hábitos alimentares e o risco de desenvolvimento de câncer de estômago: tanto podendo ter efeito carcinogênico gástrico, como fator protetor, sugerindo que os antioxidantes como as vitaminas A, C e E diminuem o risco desse tipo de câncer. Não se conhece a influência desses fatores alimentares na metaplasia intestinal gástrica. MATERIAL: Trata-se de estudo caso-controle, observacional, para o qual foram avaliados 320 pacientes com dispepsia funcional, separados em dois grupos, um grupo de casos I (indivíduos com metaplasia intestinal) teve seus hábitos alimentares comparados aos do grupo de casos-controle (sem metaplasia intestinal), através de um questionário de frequência de consumo alimentar. RESULTADOS: Ao analisarmos o padrão alimentar dos pacientes dispépticos funcionais com metaplasia intestinal e compará-lo com o padrão daqueles que não possuem metaplasia intestinal, constatou-se que os pacientes com metaplasia intestinal consomem mais alimentos como os enlatados e defumados, enquanto os pacientes sem metaplasia intestinal apresentam consumo expressivamente maior de frutas em geral e vegetais. Diferença no padrão de consumo de sal não foi identificada. CONCLUSÕES: Através dos resultados obtidos no presente estudo podemos supor que a modificação da dieta, por meio da diminuição na ingestão de alimentos como defumados e enlatados e acréscimo na ingestão de frutas e vegetais pode levar a diminuição de casos de metaplasia intestinal.
