Objective This study evaluated the knowledge and practices of pediatricians and nutritionists about cow’s milk protein allergy in infants, with an emphasis on issues related to the exclusion diet and nutritional status. Methods A cross-sectional, descriptive study was performed with a convenience sample of 204 pediatricians and 202 nutritionists randomly invited in scientific events in the city of São Paulo, from November 2014 to March 2016. Results Between 1.5% and 21.0% of respondents indicated inadequate products for the treatment of cow’s milk protein allergy, including goat’s milk, beverages or juices based on soy extract, lactose-free milk formula and partially hydrolyzed formula. The daily calcium recommendation for children between zero and 36 months of age was correctly indicated by 27.0% of pediatricians and 46.0% of nutritionists (p=0.001). Additionally, 96.1% of pediatricians and 82.7% of dietitians (p<0.001) provided guidance on about labels of industrialized products. Conclusion Pediatricians and nutritionists present gaps in knowledge about cow’s milk protein allergy treatment in infants and educational strategies that increase the knowledge of the professionals are important for the management of cow’s milk protein allergy.
Objective: To evaluate the outcome of food intake and nutritional status post discontinuation of a cow’s-milk-free diet after a negative oral food challenge.Methods: This was a prospective, uncontrolled study that evaluated food intake and nutritional status of a cohort of 80 infants and children under 5 years of age. Food intake and nutritional status were evaluated on the day of the oral food challenge test and after 30 days. Weight and height were measured on the day of the test and after 30 days.Results: The mean age of the patients was 18.7 ± 12.4 months, and 58.7% were male. After discontinuation of the elimination diet, the children showed daily intake increases in (P < 0.001), protein (P < 0.001), carbohydrates (P = 0.042), calcium from foods (P < 0.001), calcium from foods and supplements (P < 0.001), phosphorus (P < 0.001), and vitamin D from foods (P = 0.006). The Z-scores (n = 76) on the day of the oral food challenge test and 30 days after restarting the consumption of cow’s milk were as follows: weight-for-age (P < 0.001) and height-for-age (P < 0.001), respectively.Conclusion: Cow’s milk protein in the diet was associated with increased intake of energy, proteins, carbohydrates, calcium, phosphorus, and vitamin D, in addition to an increase in the Z-scores for weight-for-age and height-for-age.
RESUMENObjetivo: Levantamiento en la literatura científica sobre la eficacia de la suplementación de creatina en la ganancia de fuerza e hipertrofia muscular en practicantes de entrenamiento de fuerza. Métodos: Se realizó un levantamiento bibliográfico, basado en artículos científicos obtenidos en las bases de datos de la Biblioteca Virtual en Salud (Bvs), en el portal Scientific Eletronic Library Online (Scielo), Lilacs, Bireme y Pubmed. Resultados: Estudios encontrados mostraron que la cretina puede ser utilizada como ayuda ergogénica en el entrenamiento de fuerza, pero su eficacia sigue siendo controvertida. Consideraciones finales: Suplementación de creatina debe ser realizada con cautela por el profesional de la salud, siendo necesaria una evaluación cuidadosa tomando en consideración las necesidades y particularidades de cada individuo, el tipo de actividad física, la dosis a ser utilizada y el tiempo de duración de la suplementación.Palabras clave: Suplementos nutricionales, Efectos ergogénicos, Creatina. INTRODUÇÃONas últimas décadas, houve uma crescente preocupação com a estética corporal e, principalmente, com o crescimento muscular, levando os praticantes de musculação utilizar cada vez mais suplementos nutricionais como forma de auxílio ergogênico, associados ao treinamento (KREIDER et al., 2010).
Objective: To compare the effectiveness of extensively hydrolyzed protein-based formula (EHF) or amino acid–based formula (AAF) in reversing the weight and height deficit in infants on a cow’s milk protein elimination diet. Methods: Infants from a retrospective cohort who were fed EHF (n = 17) or AAF (n = 16) for at least 2 months on a cow’s milk protein elimination diet were included. The weight and height values recorded in the infants’ medical records were obtained. Results: The mean age of the infants at the start of EHF and AAF were 5.8 ± 2.6 and 4.4 ± 2.5 months, respectively (P = 0.061). There was no difference between the groups in terms of the monthly weight gain (373.0 ± 212.2 and 453.1 ± 138.5 g, P = 0.223, respectively, for EHF and AAF), while the monthly increase in height was greater in the group fed with AAF (1.3 ± 0.5 and 1.8 ± 0.6, P = 0.030). A comparison between the difference in the initial z-score and in the oral challenge test of weight-for-age (+0.7 ± 1.2 and +1.3 ± 1.4, P = 0.262, respectively, for the EHF and AAF groups), height-for-age (+0.2 ± 1.1 and +1.2 ± 1.8, P = 0.090), and body mass index (BMI)-for-age (+0.7 ± 1.3 and +0.7 ± 1.5, P = 0.971) did not reveal a statistically significant difference between the groups. Correlation coefficients showed that the greater the initial nutritional deficit, the greater the positive variation between the beginning of each formula and the oral challenge test. Conclusion: EHF and AAF provided similar increases in the weight-for-age, height-for-age, and BMI-for-age z-scores in both groups. The monthly increase in height was greater in infants who received AAF.
