“…Empregando-se equações padronizadas, a MCM obtida pela BIA foi superestimada, quando comparada com os valores obtidos pela pesagem hidrostática 22 . Utilizando a pletismografia de deslocamento aéreo, determinou-se que a MCG é superestimada em mulheres (1,3kg) e subestimada em homens (5,6kg, p<0,05) 23 . Recentemente, foram desenvolvidas equações preditivas de BIA específicas para obesos, com o objetivo de melhorar a precisão e a acurácia da quantificação da gordura corporal 23 .…”

ObjetivoO objetivo da pesquisa foi determinar a perda de massa corporal magra em pacientes após cirurgia bariátrica. MétodosO estudo retrospectivo foi conduzido com 17 prontuários de mulheres obesas submetidas à Derivação Gástrica em Y de Roux com anel de contenção gástrica, incluindo dados obtidos no período pré-operatório imediato e no 1º, 3º, 6º e 12º meses após a cirurgia. Os dados obtidos no prontuário incluíram a idade, medidas de peso, de altura e massa corporal magra e gorda, calculados pela impedância bioelétrica. ResultadosA média de idade das pacientes foi de 43,1, DP=7,7 anos e durante o seguimento houve diminuição significativa do índice de massa corporal [51,2 (40,2-74,1) para 33,7 (24,8-53,4)kg/m 2 ] e da massa corporal gorda [67,5 (51,2-67,4) para 32,1 (16,4-61,9)kg] em 12 meses de seguimento. No primeiro mês após a cirurgia, houve diminuição da massa corporal magra (M=65,3, DP=7,6 para M=59,7, DP=8,1kg), que representou 8,5% em relação aos valores iniciais, sendo que a partir daí, os dados mantiveram-se constantes. ConclusãoA perda de massa corporal magra pode refletir uma alteração no metabolismo proteico durante o pós-operatório imediato da cirurgia bariátrica, que pode implicar em evolução clínica e nutricional desfavoráveis.Termos de indexação: Cirurgia bariátrica. Composição corporal. Impedância elétrica. Nutrição em saúde pública. Perda de peso.

“…Thus, 2 new predictive equations of BF were generated after the BIA measurements were made, and these predicted BF with higher accuracy, precision, limits of agreement, and concordance correlation coefficients than the standard BIA equation. 40 The treatment of choice for extremely obese patients who have already undergone a distinct clinical approach is surgery. This intervention can affect several metabolic aspects of a patient, including insulin sensitivity and metabolic syndrome (MS).…”

“…Furthermore, decreases in postoperative morbidity and length of hospital stay represent important cost savings. 40,42 While preoperative immunonutrition for malnourished patients has been shown to be beneficial, patients who demand adjuvant oncological treatment have been found to have an increased risk of malnutrition and a worse outcome. Gonçalves Dias et al 45 evaluated modifications of diet intake after 3 types of nutrition interventions were administered to 64 male outpatients undergoing head and neck radiotherapy.…”

It is a great honor to present the 2015 Rhoads Lecture and to discuss strategies for high-quality nutrition therapy (NT), as well as to address the problem of malnutrition in Brazilian hospitals.Dr Rhoads is known for his outstanding achievements in nutrition care, and his unquestionable legacy is demonstrated by the translation of his many scientific papers and books into several languages. The importance of artificial nutrition in the overall care of a patient is reflected in Dr Rhoads's own words: "intravenous feeding is one of the rare things in Medicine that has turned out to be better than its sponsors anticipated." Moreover, when Dr Rhoads was awarded for his contributions and leadership in the field of nutrition, in his speech, he referred to a quote by Nobel laureate economist Milton Friedman: "success lies on the degree to which one's ideas and contributions become embedded in the body of knowledge that comprised one's discipline."1 Indeed, we are here to confirm the veracity of this statement regarding Dr Rhoads's scientific contributions.Accumulating evidence supports the utmost relevancy of artificial nutrition, including oral nutrition, enteral nutrition (EN), and parenteral nutrition (PN), as one of the cornerstones of patient care. Nonetheless, for the full success of NT to be achieved, it is imperative that standardized procedures be followed to prevent life-threatening associated complications and, above all, to avoid the "one-size-fits-all" practice of nutrition, which should be condemned by those following the evidence behind science. History of NT in BrazilHere, the steps that have helped Brazil implement an NT practice are presented and discussed. The statements herein are based on the experience and data of the authors, although we also acknowledge and cite the work of other professionals who have contributed to the development of NT practice in Brazil. In combination, these scientific data highlight the importance of applying advances in laboratory research to the clinical setting to improve patient care. First, we review the history of clinical nutrition in Brazil, with a particular emphasis on the role of nutrition screening and nutrition assessment as demonstrated by a malnutrition prevalence study that encompassed 4000 patients.2 Next follows a discussion of to whom, when, and what NT should be administered, particularly regarding immunonutrition and parenteral lipid emulsions. Finally, strategies that have been used to implement hospital clinical nutrition are presented, with a focus on patients with short bowel syndrome (SBS) and obesity. The outcomes, costs, quality control, and education in clinical practice that are currently involved with these strategies are also presented, as well as how these strategies have the potential to affect perspectives.Very briefly, Brazil is a country that has approximately 200 million inhabitants, 10% of whom are elderly. Life expectancy AbstractStrategies for improving nutrition therapy (NT) are of utmost importance in any healthcare system. The ...

“…Mathematic formulas were created for healthy populations of different ethnicities, different age groups, varied degrees of daily physical activity, and populations suffering from particular conditions and diseases (6,7). However, to date no equations have been developed specifically for predicting body composition in TS patients despite its particular anthropometric characteristics (8).…”

Introduction: Cardiovascular disease is one of the main causes for Turner syndrome (TS) mortality and the evaluation of its risk factors such as excess body fat and its distribution is considered one of the major aspects of the adult patient care. Objective: To develop and validate a specific bioelectrical impedance analysis (BIA) equation to predict body composition in TS patients. Subjects and methods: Clinical and anthropometric data, dual-energy X-ray absorptiometry (DXA) for total fat-free mass (FFM) and BIA for resistance and reactance were obtained from 50 adult TS patients. Linear regression analysis was performed with multiple clinical and BIA data to obtain a predicting equation.
