A recidiva de peso ocorreu em 18 (39%) dos indivíduos, a partir principalmente dos 12 meses após a cirurgia. Observou-se que a renda familiar mensal superior a 4000 reais e a frequência a consultas com nutricionista inferior a três vezes no pré-operatório estiveram associadas a maior chance de recidiva de peso. Conclusões: Nessa amostra, a baixa assiduidade às consultas nutricionais no pré-operatório, bem como a renda familiar elevada foram fatores de risco para recidiva de peso no pós-operatório tardio de cirurgia bariátrica. DESCRITORES: cirurgia bariátrica; obesidade; programas de nutrição. ABSTRACT Aims:To evaluate risk factors for weight regain in patients undergoing bariatric surgery. Methods: Cross-sectional study using self-administered online questionnaire. The questionnaire asked about factors that can be associated with weight regain after bariatric surgery. Weight, height, sex, age, education, income, and nutrition appointment attendance before and after surgery were registered. Body mass index, weight loss, and loss of excess weight in the immediate postoperative period and at 6, 12, and 24 months postoperatively, as well as at the time of completing the questionnaire, were evaluated. Weight regain was evaluated according to the lowest weight achieved since surgery. The Three Factor Eating Questionnaire-21 was used to classify eating behavior into Emotional Eating, Cognitive Dietary Restraint, or Uncontrolled Eating. Results: The questionnaire was answered by 46 individuals who underwent bariatric surgery, with a mean age of 38±8.78 years and a median of three postoperative years. Forty-three (93.5%) patients were female. The mean loss of excess weight and current weight loss were 78.56±16.12% and 35.24±8.19%, respectively. The current body mass index was 27.35±3.98 kg/m 2 . Emotional eating was observed in 18 (39.13%), cognitive restraint in 24 (52.17%), and emotional eating associated with cognitive restraint in 4 (8.69%) of the respondents. Eighteen individuals (39%) regained weight, especially after 12 months. A monthly family income greater than 4000 Brazilian Reals and nutrition appointments fewer than three in the preoperative period were associated with a larger probability of weight regain. Conclusions: In this sample, low nutrition appointment attendance in the preoperative period and a high family income were risk factors for weight regain in the late postoperative period of bariatric surgery.

Resumo O estudo teve por objetivo avaliar a comercialização de alimentos em cantinas comerciais localizadas no âmbito escolar de diferentes redes de ensino, tipos de administração e presença ou não de profissional técnico (nutricionista). O estudo do tipo observacional foi realizado em 111 cantinas, sendo 35 estabelecimentos de ensino privado e 76 de ensino público de Curitiba, Paraná, Brasil. Para realizar estas avaliações, foi elaborada uma lista de verificação contendo um conjunto de condutas baseada nas legislações estaduais do Paraná. De acordo com as legislações vigentes, constatou-se que 97,37% das cantinas das instituições públicas e 94,29% das privadas comercializavam alimentos considerados proibidos por apresentarem baixo valor nutricional. Os principais alimentos proibidos comercializados nas cantinas foram os salgadinhos industrializados, os chocolates, as balas e os sucos artificiais. Esses também foram os alimentos e bebidas mais vendidos, segundo os responsáveis. Além disso, 73,87% das cantinas não possuíam supervisão técnica, 89,19% não disponibilizavam dois tipos de frutas e apenas 1,80% tinha mural educativo, conforme exigido pelas legislações vigentes. Conclui-se que as cantinas, independentemente da rede ensino e do tipo de administração, estão em desacordo com as legislações vigentes, tanto na comercialização de alimentos proibidos como na ausência de dois tipos de frutas e na ausência de mural educativo. Os resultados mostraram que a supervisão frequente do responsável técnico se faz necessária para contribuir nas escolhas dos alimentos comercializados e, consequentemente, melhorar a qualidade nutricional dos produtos expostos para venda.

This article aims to develop a literature review of food nutrients and substances that can impact on thyroid function. A literature review using association between hypothyroidism descriptors, iodine, selenium, zinc, soy, gluten and flavonoids was held in Pubmed database in 2014. It was found 172 articles and 42 were elected, besides material needed to achieve the objective of this study. It was observed that iodide participates in the reaction organification and subsequently engages tyrosyl residues to form the thyroid hormones. Excessive or deficient amounts of iodine contribute to thyroid dysfunction, including hypothyroidism. Selenium and zinc are co-factors for deiodination reactions, which convert thyroxine (T4) in triiodothyronine (T3) peripherally. Deficiency of these minerals can be developed on restrictive diets or unbalanced diet at any stage of life, collaborating with decreased production of thyroid hormones. Furthermore, intaken substances, such as thiocyanate and isothiocyanate can compete with iodide for the entry in thyroid follicles and compromise hormones synthesis, as well as soy, which can inhibit thyroid peroxidase, enzyme responsible for the oxidation of iodide and formation of thyroid hormones, when there is iodine deficiency. In vivo studies that show the type and amount of flavonoids that may interfere with the conversion of T4 to T3 should be performed, as well as studies to elucidate the role of the exemption of gluten in the reversal of subclinical hypothyroidism.

AIMS: To verify the relationships between the dialysis adequacy index (Kt/V) and nutritional parameters of individuals with chronic renal disease on hemodialysis.METHODS: A retrospective study was performed at a hemodialysis institute. Data on sex, age, biochemical tests, dry weight, height, arm circumference (AC) and triceps skin fold (TSF) were collected from the medical charts. Nutritional risk index (NRI), body mass index (BMI), arm muscle circumference (AMC), corrected arm muscle area (AMAc), Kt/V and urea reduction rate (URR). The Mann-Whitney test and the Spearman correlation were used for the statistical analysis, and a p<0.05 was considered significant.RESULTS: A total of 164 patients were evaluated, with a mean age of 58±14.4 years, of which 96 (59%) were male. The median time on hemodialysis was 35.0 (5-234). Among the 164 patients, 60 (37%) presented nutritional risk. In the evaluation of nutritional status, the mean values obtained were 25.0±4.5 kg/m2 for BMI, 99.0±12.3% for CB adequacy, 86.7±14.5% for WBC adequacy, 122.9±66.8% for CBA adequacy and 1.4±0.4 for Kt/V. The median adequacy for PCT was 107.8% (11.5%-305.4%). There was no correlation of Kt/V with serum albumin, CB, CMB, AMAc and NRI. Kt/V had a low positive correlation with time on hemodialysis (r = 0.2197) and a low negative correlation with PCT (r = -0.1692) and with BMI (r = -01970). The correlation between Kt/V and dry weight was moderate and negative (r = -0.3710) and between Kt/V and URR the correlation was strongly positive (r = 0.81129).CONCLUSIONS: Adequate dialysis efficiency and good nutritional status were observed in most patients of the evaluated sample, with significant correlations between dialysis adequacy and parameters of nutritional status assessment.
