Resumo Objetivo: realizar uma revisão na literatura sobre a terapia nutricional utilizada no tratamento da lesão por pressão. Métodos: revisão sistemática nas bases de dados PubMed, Lilacs e SciELO, selecionando publicações realizadas nos últimos cinco anos, na língua inglesa e portuguesa. Resultado: foram analisados três artigos que pesquisaram o uso de diferentes doses de arginina, mistura de aminoácidos e suplemento nutricional enriquecido com arginina, zinco e antioxidantes. Nos estudos, houve redução na área das feridas nos grupos de intervenção, entretanto não foi significativa em todas as pesquisas. Conclusão: a intervenção nutricional deve ser considerada parte integrante do tratamento da lesão por pressão. O uso de determinados nutrientes podem interferir positivamente no processo de cicatrização das lesões por pressão. Devido à heterogeneidade das metodologias usadas, do pequeno tamanho da amostra, a diversidade no tempo de intervenção e de nutrientes utilizados, recomendam-se estudos cientificamente mais rigorosos para criar um modelo de intervenção nutricional baseado em evidências no tratamento de lesão por pressão.

Abstract Objective: to review literature on the use of nutritional therapy in the treatment of pressure injuries. Methods: a systematic review of the PubMed, Lilacs and Scielo databases was performed, with studies in the English and Portuguese languages published in the last five years selected. Result: three articles that investigated the use of different doses of arginine, a mixture of amino acids and nutritional supplements enriched with arginine, zinc and antioxidants were analyzed. The studies found that there was a reduction in the area of wounds in the intervention groups, although the difference in size was not significant in all the articles. Conclusion: nutritional intervention should be considered an integral part of the treatment of pressure injuries. The use of certain nutrients may positively affect the healing process of such injuries. Due to the heterogeneity of the methodologies used, the small sample size and the range of intervention times and nutrients used, more scientifically rigorous studies are recommended to create an evidence based nutritional intervention model for the treatment of pressure injuries.

Introduction and aims: Microbial contamination of enteral feeding and infant formulas can result in a risk of worsening of the clinical condition of the patients, who are already weakened and susceptible to pathogens. The objective was to evaluate aspects of the management of quality hygienic - sanitary of enteral feeding and infant formulas in hospitals, focusing on the structure, process and outcome. Methods: An observational, descriptive, prospective, with quantitative and qualitative variables study was done. The survey was conducted for 12 months and 227 samples of enteral feeding and 176 of infant formula were collected in Nutrition and Dietetic Services of Health Secretary / Federal District. In evaluating the operating conditions, the Tool 2 was applied to: Enteral Nutrition Preparation. Data were analyzed from the unified Donabedian's triad for evaluation of health services. Results: The results obtained with the Tool 2 demonstrated that the Storage Block complies with legal requirements. Moreover, Dressing Block is a risk factor for the contamination. From the 403 samples, 56% corresponded to samples of Enteral Nutrition and 44% to samples of Infant Formulas. The data indicate that from 227 samples of Enteral Nutrition, 6.2% were in disagreement with the legislation, while from 176 samples of Infant Formulas, 4.6% were also in disagreement with the legislation. Conclusion: The ineffective implementation of the sanitary and hygienic requirements during the preparation results in a microbiologically unsafe product to patients in debilitated health state, and the count of mesophilic microorganisms can be a good indicator of microbiological safety.

Introducción y objetivo: La contaminación microbiológica de dietas enterales y fórmulas infantiles puede conducir a una situación de riesgo de agravación del cuadro clínico de pacientes, ya debilitados y susceptibles a los agentes patógenos. El objetivo fue evaluar aspectos de la gestión de calidad de condiciones sanitarias de dietas enterales y fórmulas infantiles en los hospitales, centrándose en estructura, proceso y resultado. Métodos: Fue hecho un estudio observacional, descriptivo, prospectivo, con variables cuantitativas y cualitativas. La encuesta fue por 12 meses y se recogieron 227 muestras de dietas enterales y 176 de fórmulas infantiles en los Servicios de Nutrición y Dietética de la Secretaría de Estado de Salud del Distrito Federal. Los datos fueron analizados a partir de la Tríada de Donabedian para la evaluación de los servicios de salud por medio de un cuestionario. Resultados: Los resultados obtenidos muestran que en Bloque Almacenamiento cumple con los requisitos legales. Por otro lado, el Bloque Vestuario es un factor de riesgo de contaminación. De las 403 muestras, 56% eran muestras de Nutrición Enteral y 44%, muestras de Fórmulas Infantiles. Los datos indican que de 227 muestras de Nutrición Enteral, un 6,2% estaban en desacuerdo con la ley, mientras que de las 176 muestras de las Fórmulas Infantiles, 4,6% también estaban en desacuerdo con la legislación. Conclusión: La falta de aplicación efectiva de requisitos higiénicos sanitários durante la preparación resulta en producto microbiológicamente inseguro para pacientes debilitados, y el recuento de mesófilos totales puede ser un buen indicador de la seguridad microbiológica.

This study to assessed 47 cystic fibrosis (CF) patients assisted by a program of Home Enteral Nutrition. Anthropometric measurements included weight, height, triceps skinfold thickness, waist circunference and spirometry was also performed. Enzymes, nutritional and fat-soluble vitamin supplementations were recorded. There were no associations with enzymes and vitamin supplements between groups that did or did not have a nutritional deficit. Spirometry of patients without nutritional deficit, utilizing the European and American Consensus, showed that the ratio of FEV1 ≥ 80% was statistically greater than the ratio of FEV1<80% (p=0.0459 and 0.0230, respectively). The proportion of patients without nutritional deficit was statistically lower in those who use supplements compared to those who did not. than when considers both Consensus (p=0.0210 and 0.0098, respectively). CF patients with FEV1 <80% and arm circumference <5th percentile showed statistically significant. The associations between nutritional deficits and altered pattern of spirometry are common situations among CF patients.

El presente estudio evaluó 47 pacientes con fibrosis quística (FQ) con la asistencia de un Programa de Nutrición Enteral Domiciliaria. Se tomaron medidas antropométricas de peso, talla, pliegue del tricipital y circunferencia de cintura y espirometría. Se registraron las enzimas y suplementos de vitaminas solubles en grasa. No encontraron asociaciones con el uso de suplementos de vitaminas y enzimas entre los grupos que teníamos no tenían déficit nutricional. La espirometría de los pacientes "sin déficit nutricional", para el consenso americano y europeo, tiene uma tasa VEF1 ≥ 80% estadísdicamente superior a la tasa de VEF1 < 80% (0.0459 y 0.0230, respectivamente).La tasa de pacientes com FQ "sin déficit nutricional" y usando suplementos fue estadísticamente más bajos que los que no usaban , cuando se consideran los dos consenso (p=0.0210 y 0.0098, respectivamente). La prueba de función pulmonar de los pacientes con FQ com VEF 1 < 80% y circunferencia del brazo < percentil 5 mostraron una asociación estadísticamente significativa (p= 0.0021).Las asociaciones entre déficit nu-tricional y espirometría se encontraron muy frecuentemente entre los pacientes con FQ.
