ABSTRACT

ABSTRACT Objective To evaluate the agreement between the modified version of the Nutritional Risk in the Critically Ill Score (without Interleukin-6) and a variant composed of C-Reactive Protein as well as its capacity to predict mortality. Methods A prospective cohort study was carried out with 315 patients in an Intensive Care Unit of a university hospital from October 2017 to April 2018. The agreement between the instruments was evaluated using the Kappa test. The predictive capacity for estimating mortality was assessed with the Receiver Operating Characteristic curve. Results The critical patients involved in the study had a mean age of 60.8±16.3 years and 53.5% were female. Most patients had C-Reactive Protein levels ?10mg/dL (n=263, 83.5%) and their admission in the Intensive Care Unit was medical (n=219, 69.5%). The prevalence of mortality was observed in 41.0% of the evaluated patients. The proportions at high nutritional risk according to Nutritional Risk in the Critically Ill without Interleukin-6 and with C-Reactive Protein were 57.5% and 55.6%, respectively. The tools showed strong and significant agreement(Kappa=0.935; p=0.020) and satisfactory performances in predicting mortality (area under the curve 0.695 [0.636-0.754] and 0.699 [0.640-0.758]). Conclusion Both versions of the Nutritional Risk in the Critically Ill tool show a satisfactory agreement and performance as predictors of mortality in critically ill patients. Further analysis of this variant and the association between nutrition adequacy and mortality is needed.


RESUMO Objetivo Avaliar a concordância entre a versão modificada do Escore de Risco Nutricional em Pacientes Críticos (sem Interleucina-6) e uma variante composta de Proteína C-Reativa, bem como a capacidade de ambas as versões para predizer mortalidade em pacientes críticos. Métodos Trata-se de um estudo de coorte prospectivo em 315 pacientes admitidos em uma Unidade de Tratamento Intensivo de um hospital universitário brasileiro no período de outubro de 2017 a abril de 2018. A concordância entre os instrumentos foi avaliada pelo teste Kappa. A capacidade preditiva de mortalidade foi avaliada pela curva Receiver Operating Characteristic. Resultados Os pacientes apresentaram idade média de 60,8±16,3 anos, dos quais 53,5% eram mulheres. A maioria dos pacientes apresentou níveis de Proteína C-Reativa ?10mg/dL (n=263; 83,5%). O tipo de admissão na Unidade de Terepia Intensiva foi clínica (n=219; 69,5%), sendo que a prevalência da mortalidade foi observada em41,0% dos pacientes avaliados. O alto risco nutricional, avaliado pelo Nutritional Risk in the Critically Ill sem Interleucina-6 e pela variante com Proteína C-Reativa, foi demonstrado em 57,5% e 55,6% dos pacientes críticos, respectivamente. Os instrumentos demostraram concordância forte e significativa (Kappa=0,935; p=0,020) e desempenho satisfatório para predizer mortalidade (área sob a curva 0,695 [0,636-0,774] e 0,699 [0,640-0,758]). Conclusão Ambas as versões do Escore de Risco Nutricional em Pacientes Críticos apresentam boa concordância e desempenho satisfatório como preditores de mortalidade em pacientes críticos. É ainda necessária uma análise mais aprofundada desta variante, bem como da associação entre adequação nutricional e mortalidade.

ABSTRACT

RESUMO Objetivo: Avaliar possíveis associações do risco nutricional com os desfechos clínicos desfavoráveis em pacientes críticos internados na unidade de terapia intensiva. Métodos: Estudo de coorte, prospectivo, realizado em 200 pacientes em unidade de terapia intensiva de hospital universitário. O risco nutricional foi avaliado pelos escores NRS-2002 e NUTRIC. Pacientes com escore ≥ 5 foram considerados de alto risco nutricional. Os dados e desfechos clínicos foram obtidos de registros clínicos dos pacientes. Utilizou-se análise de regressão logística múltipla para calcular os riscos relativos e seus respectivos intervalos de confiança de 95% para os desfechos clínicos. Resultados: Os pacientes críticos apresentaram idade de 59,4 ± 16,5 anos, e 53,5% eram do sexo feminino. O alto risco nutricional, segundo NRS-2002 e NUTRIC, foi de 55% e 36,5%, respectivamente. Em modelos de regressão logística múltipla, ajustados por sexo e motivo de internação, o alto risco nutricional avaliado pelo NRS-2002 associou-se positivamente ao uso de ventilação mecânica (RR = 2,34; IC95% 1,31 - 4,19; p = 0,004); presença de infecção (RR = 2,21; IC95% 1,24 - 3,94; p = 0,007) e óbito (RR = 1,86; IC95% 1,01 - 3,41; p = 0,045). Quando avaliado pelo NUTRIC, o risco nutricional foi associado à terapia de substituição renal (RR = 2,10; IC95% 1,02 - 4,15; p = 0,040) e óbito (RR = 3,48; IC95% 1,88 - 6,44; p < 0,001). Conclusão: Em pacientes gravemente doentes, o alto risco nutricional foi positivamente associado a um maior risco de desfechos clínicos desfavoráveis, incluindo óbito hospitalar.


ABSTRACT Objective: To evaluate possible associations between nutritional risk and the clinical outcomes of critical patients admitted to an intensive care unit. Methods: A prospective study was carried out with a cohort comprising 200 patients admitted to a university hospital intensive care unit. Nutritional risk was assessed with the NRS-2002 and NUTRIC scores. Patients with scores ≥ 5 were considered at high nutritional risk. Clinical data and outcome measures were obtained from patients' medical records. Multiple logistic regression analysis was used to calculate odds ratios and their respective 95% confidence intervals (for clinical outcomes). Results: This sample of critical patients had a mean age of 59.4 ± 16.5 years and 53.5% were female. The proportions at high nutritional risk according to NRS-2002 and NUTRIC were 55% and 36.5%, respectively. Multiple logistic regression models adjusted for gender and type of admission indicated that high nutritional risk assessed by the NRS-2002 was positively associated with use of mechanical ventilation (OR = 2.34; 95%CI 1.31 - 4.19; p = 0.004); presence of infection (OR = 2.21; 95%CI 1.24 - 3.94; p = 0.007), and death (OR = 1.86; 95%CI 1.01 - 3.41; p = 0.045). When evaluated by NUTRIC, nutritional risk was associated with renal replacement therapy (OR = 2.10; 95%CI 1.02 - 4.15; p = 0.040) and death (OR = 3.48; 95%CI 1.88 - 6.44; p < 0.001). Conclusion: In critically ill patients, high nutritional risk was positively associated with an increased risk of clinical outcomes including hospital death.

ABSTRACT

ABSTRACT Objectives: The aims of this study are to investigate which of the seven selected predictive equation for estimating basal metabolic rate (BMR) is the best alternative to indirect calorimetry (IC) and to evaluate the dietary energy intake in patients with type 2 diabetes. Subjects and methods: Twenty-one patients with type 2 diabetes participated in this diagnostic test study. Clinical and laboratorial variables were evaluated as well as body composition by absorptiometry dual X-ray emission (DXA) and BMR measured by IC and estimated by prediction equations. Dietary intake was evaluated by a quantitative food frequency questionnaire. Data were analyzed using Bland-Altman plots, paired t-tests, and Pearson's correlation coefficients. Results: Patients were 62 (48-70) years old, have had diabetes for 8 (2-36) yeas, and 52.4% were females. The mean body composition comprised a fat-free mass of 49.8 ± 9.4 kg and a fat mass of 28.3 ± 7.2 kg. The energy intake was 2134.3 ± 730.2 kcal/day and the BMR by IC was 1745 ± 315 kcal/day. There was a wide variation in the accuracy of BMR values predicted by equations when compared to IC BMR measurement. Harris-Benedict, Oxford, FAO/WHO/UNO equations produced the smallest differences to IC, with a general bias of < 8%. The FAO/WHO/UNO equation provided the best BMR prediction in comparison to measured BMR. Conclusion: In patients with type 2 diabetes, the equation of the FAO/WHO/UNO was the one closest to the BMR values as measured by IC.

ABSTRACT

ABSTRACT Objective To evaluate the nutritional status and functional capacity of hospitalized adult patients. Methods Cross-sectional study of adult oncology patients at Hospital de Clínicas de Porto Alegre. Patients were evaluated according to Solid Tumors and Hematologic Tumors. The nutritional status was obtained using Patient Generated Subjective Global Assessment, and the functional capacity was evaluated by Handgrip Strength using a Jamar® dynamometer - and the Performance Index of the Eastern Cooperative Oncology Group. Results This study evaluated 76 patients (56±17 years old, 35.5% female), 63.2% with Solid Tumors and 36.8% with Hematologic Tumors. According to the Patient Generated Subjective Global Assessment, 53.9% of the patients were moderately and severely malnourished and demonstrated functional capacity, according to the Handgrip Strength and Performance Index of the Eastern Cooperative Oncology Group, of 47.9% and 32.2%, respectively. The functional capacity instruments showed a moderate agreement (Kappa=0.427, p<0.001) and positive correlation (r=0.136, p=0.028). Severely malnourished patients had a lower Handgrip Strength when compared to well nourished (24.0±10.4 vs. 34.2±16.6kg, p=0.015). The results were confirmed among moderately and severely malnourished patients, who were rated at the 40 percentile, considered low functional capacity. Conclusion In this study, hospitalized oncological patients presented poor nutritional status and low functional capacity. The Patient Generated Subjective Global Assessment identifies the nutritional specification earlier. In addition, Handgrip Strength dynamometry can be a useful tool to evaluate the low functional capacity and nutritional status. It can be included in cancer patient's evaluation, along with other nutritional assessment tools.


RESUMO Objetivo Avaliar o estado nutricional e capacidade funcional de pacientes adultos oncológicos hospitalizados. Métodos Estudo transversal em pacientes oncológicos adultos do Hospital de Clínicas de Porto Alegre. Os pacientes foram divididos de acordo com a presença de Tumores Sólidos e Tumores Hematológicos. O estado nutricional foi identificado pela Avaliação Subjetiva Global Produzida pelo Paciente e a capacidade funcional pela Força do Aperto de Mão - medida por dinamometria - e pelo Índice de Desempenho do Eastern Cooperative Oncology Group. Resultados Foram avaliados 76 pacientes (56±17 anos, 35,5% do sexo feminino), 63,2% apresentaram Tumores Sólidos e 36,8% Tumores Hematológicos. De acordo com a Avaliação Subjetiva Global Produzida pelo Paciente, 53,9% dos pacientes estavam moderadamente e gravemente desnutridos e demonstraram baixa capacidade funcional de acordo com a Força do Aperto de Mão e Índice de Desempenho do Eastern Cooperative Oncology Group, 47,9% e 32,2%, respectivamente. Os instrumentos de capacidade funcional demonstraram uma concordância moderada (Kappa=0,427; p<0,001) e correlação positiva (r=0,136; p=0,028). Pacientes gravemente desnutridos demonstraram ter uma menor Força do Aperto de Mão quando comparados aos bem nutridos (24,0±10,4 vs. 34,2±16,6kg; p=0,015). Resultados foram confirmados entre pacientes moderadamente e gravemente desnutridos que apresentaram Força do Aperto de Mão abaixo do percentil 40, considerado uma baixa capacidade funcional. Conclusão Neste estudo, os pacientes oncológicos hospitalizados, independentes do tipo de tumor, apresentaram comprometimento do estado nutricional e baixa capacidade funcional. A Avaliação Subjetiva Global Produzida pelo Paciente identifica de forma mais precoce a necessidade de uma intervenção nutricional especifica. Ainda, a Força do Aperto de Mão deve ser considerada para complementar a avaliação nutricional neste grupo de pacientes.

ABSTRACT

ABSTRACT Objective The present investigation sought to evaluate the potential association between dietary fiber intake and blood pressure (BP) in adult patients with type 1 diabetes (T1D). Subjects and methods A cross-sectional study was carried out in 111 outpatients with T1D from Porto Alegre, Brazil. Patients were predominantly male (56%) and white (88%), with a mean age of 40 ± 10 years, diabetes duration of 18 ± 9 years, BMI 24.8 ± 3.85 kg/m2, and HbA1c 9.0 ± 2.0%. After clinical and laboratory evaluation, dietary intake was evaluated by 3-day weighed-diet records, whose reliability was confirmed by 24-h urinary nitrogen output. Patients were stratified into two groups according to adequacy of fiber intake in relation to American Diabetes Association (ADA) recommendations: below recommended daily intake (< 14g fiber/1000 kcal) or at/above recommended intake (≥ 14g/1000 kcal). Results Patients in the higher fiber intake group exhibited significantly lower systolic (SBP) (115.9 ± 12.2 vs 125.1 ± 25.0 mmHg, p = 0.016) and diastolic blood pressure (DBP) (72.9 ± 9.2 vs 78.5 ± 9.3 mmHg, p = 0.009), higher energy intake (2164.0 ± 626.0 vs 1632.8 ± 502.0 kcal, p < 0.001), and lower BMI (24.4 ± 3.5 vs 26.2 ± 4.8, p = 0.044). Linear regression modelling, adjusted for age, energy intake, sodium intake, and BMI, indicated that higher fiber intake was associated with lower SBP and DBP levels. No significant between-group differences were observed with regard to duration of diabetes, glycemic control, insulin dosage, or presence of hypertension, nephropathy, or retinopathy. Conclusion We conclude that fiber consumption meeting or exceeding current ADA recommendations is associated with lower SBP and DBP in patients with T1D.

ABSTRACT

Introdução: O câncer é uma doença crônica não transmissível e afeta, de modo crescente, a população mundial. A presença da desnutrição é elevada e o estado nutricional tem um papel importante no desfecho clínico e na qualidade de vida de pacientes com câncer. O objetivo desse estudo foi identificar a prevalência dos tipos de câncer, alterações do estado nutricional e tempo de internação de pacientes adultos hospitalizados. Método: Estudo retrospectivo observacional com análise de 354 prontuários de pacientes (idade 60,6±13,8 anos; 34,2% do sexo feminino) com qualquer tipo de câncer, internados no Hospital de Clínicas de Porto Alegre. Resultados: Foi observada maior prevalência de quatro tipos de cânceres: próstata (48,8%), tireoide (26%), digestivo (19%) e ovário e mama (6,2%). Pacientes com câncer digestivo apresentaram maior tempo de internação (aproximadamente 10 dias), menor índice de massa corporal (IMC) (24,8±5,3 kg/ m²), maior prevalência de desnutrição (75%) e associação aos principais sintomas vinculados ao estado nutricional quando comparados aos pacientes com outros tipos de câncer. Indicadores do estado nutricional (IMC, presença da desnutrição, perda de peso e percentual de perda de peso em 6 meses) foram associados a um maior período de internação (p≤0,001). Conclusão: Pacientes com câncer digestivo demonstraram ter pior estado nutricional durante o seu período de internação, apresentando maior risco nutricional associado à presença da desnutrição e maior perda de peso, o que refletiu em maior tempo de permanência hospitalar.(AU)


Introduction: Cancer is a chronic disease and affect, increasingly, the world population. The presence of malnutrition is high and nutritional status plays an important role in clinical outcome and quality of life of cancer patients. The aim of this study was to identify the prevalence of cancers, nutritional status changes and length of stay of hospitalized adult patients. Methods: An observational retrospective study with analysis of 354 records of patients (age 60.6±13.8 years; 34.2% female) with any type of cancer, admitted to the Hospital de Clínicas de Porto Alegre. Results: Was observed a higher prevalence of four types of cancers: prostate (48.8%), thyroid (26%), digestive (19%) and ovarian and breast (6.2%). Patients with digestive cancer had longer hospital stay (about 10 days), lower body mass index (BMI) (24.8±5.3 kg/m²), a higher prevalence of malnutrition (75%) and association with the main symptoms linked nutritional status when compared to patients with other cancers. The indicators of nutritional status (BMI, presence of malnutrition, weight loss and percentage of weight loss at 6 months) were associated with increased hospital stay (p≤0.001). Conclusion: The patients with digestive cancer showed a poor nutritional status during their hospital stay, showing a higher nutritional risk associated with the presence of malnutrition and increased weight loss which resulted in a longer hospital stay time.(AU)

ABSTRACT

RESUMOObjetivo:Revisar sistematicamente os principais métodos para avaliação do risco nutricional utilizados em pacientes oncológicos graves e apresentar aqueles que melhor avaliam os riscos e preveem desfechos clínicos relevantes neste grupo de pacientes, além de discutir as vantagens e as desvantagens destes métodos, segundo a literatura atual.Métodos:O estudo consistiu de uma revisão sistemática com base na análise de artigos obtidos nas bases de dados PubMed, LILACS e SciELO, realizando as buscas com os termos em inglês: “nutritional risk assessment”, “critically ill” e “cancer”.Resultados:Apenas 6 (17,7%) dos 34 artigos inicialmente obtidos cumpriam os critérios para inclusão e foram selecionados para revisão. Os principais desfechos destes estudos foram que o gasto de energia em repouso se associou com subnutrição e superalimentação. O escore elevado da Avaliação Subjetiva Global - Produzida pelo Paciente associou- se de forma significante com baixa ingestão de alimentos, perda de peso e desnutrição. Em termos de marcadores bioquímicos, níveis mais elevados de creatinina, albumina e ureia se associaram de forma significante com mortalidade mais baixa. Os piores índices de sobrevivência foram encontrados para pacientes com condições de desempenho piores, conforme avaliação usando o Eastern Cooperative Oncologic Group performance status, escore prognóstico de Glasgow elevado, baixa albumina/hipoalbuminemia, elevado escore da Avaliação Subjetiva Global - Produzida Pelo Paciente e para níveis elevados de fosfatase alcalina. Valores de avaliação do Índice de Risco Nutricional Geriátrico inferiores a 87 se associaram de forma significante com mortalidade. O escore pelo índice prognóstico inflamatório nutricional se associou com condição nutricional anormal em pacientes oncológicos graves. Dentre os estudos revisados que avaliaram apenas peso e índice de massa corporal, não se encontrou qualquer desfecho clínico significante.Conclusão:Nenhum dos métodos revisados ajudou a definir o risco entre esses pacientes. Portanto, sugere-se a avaliação por meio da quantificação da perda de peso e dos níveis séricos, preferivelmente em combinação com outros métodos utilizando escores como o Eastern Cooperative Oncologic Group performance status, o escore prognóstico de Glasgow e a Avaliação Subjetiva Global - Produzida Pelo Paciente, já que seu uso é simples, factível e útil em tais casos.


ABSTRACTObjective:To systematically review the main methods for nutritional risk assessment used in critically ill cancer patients and present the methods that better assess risks and predict relevant clinical outcomes in this group of patients, as well as to discuss the pros and cons of these methods according to the current literature.Methods:The study consisted of a systematic review based on analysis of manuscripts retrieved from the PubMed, LILACS and SciELO databases by searching for the key words “nutritional risk assessment”, “critically ill” and “cancer”.Results:Only 6 (17.7%) of 34 initially retrieved papers met the inclusion criteria and were selected for the review. The main outcomes of these studies were that resting energy expenditure was associated with undernourishment and overfeeding. The high Patient-Generated Subjective Global Assessment score was significantly associated with low food intake, weight loss and malnutrition. In terms of biochemical markers, higher levels of creatinine, albumin and urea were significantly associated with lower mortality. The worst survival was found for patients with worse Eastern Cooperative Oncologic Group - performance status, high Glasgow Prognostic Score, low albumin, high Patient-Generated Subjective Global Assessment score and high alkaline phosphatase levels. Geriatric Nutritional Risk Index values < 87 were significantly associated with mortality. A high Prognostic Inflammatory and Nutritional Index score was associated with abnormal nutritional status in critically ill cancer patients. Among the reviewed studies that examined weight and body mass index alone, no significant clinical outcome was found.Conclusion:None of the methods reviewed helped to define risk among these patients. Therefore, assessment by a combination of weight loss and serum measurements, preferably in combination with other methods using scores such as Eastern Cooperative Oncologic Group - performance status, Glasgow Prognostic Score and Patient-Generated Subjective Global Assessment, is suggested given that their use is simple, feasible and useful in such cases.

ABSTRACT

Objective To examine the association between nutritional status and dietary factors in children and adolescents with cystic fibrosis that are carriers of delta F508 mutation. Methods Cross-sectional study of cystic fibrosis children and adolescents. Nutritional status (body mass index percentile) and dietary intake (3-day diet records presented as a percentage of estimated energy requirement) were assessed. Results Thirty six patients (median of 8.6; interquartile range 6.8-12.5 years; 50% male). The Poisson regression analysis showed that the carriers for delta F508 mutation had 60% lower prevalence ratio of body mass index ≥25° (PR=0.4; 95%IC=0.2-0.8) and 90% lower prevalence ratio (PR=0.1; confidence interval 95%IC=0.02-0.3) of ≥150% of estimated energy requirement when compared with non-delta F508 mutation carriers. The model was adjusted for lung function, estimated energy requirement, and body mass index. Conclusion Carriers for delta F508 mutation showed lower body mass index percentile and lower daily caloric consumption when compared with patients without this mutation. .


Objetivo Avaliar a associação entre estado nutricional e fatores dietéticos na fibrose cística em crianças e adolescentes portadores da mutação delta F508. Métodos Estudo transversal com crianças e adolescentes com fibrose cística. Foram avaliados o estado nutricional (índice de massa corporal em percentil) e consumo alimentar (três registros alimentares apresentados em porcentagem da necessidade de energia estimada). Resultados Foi avaliado um total de 36 pacientes (mediana de 8,6; intervalo interquartil de 6,8-12,5 anos; 50% do sexo masculino). Na regressão de Poisson, pacientes com a mutação delta F508 apresentaram uma razão de pre-valência 60% menor de índice de massa corporal ≥25° (RP=0,4; IC95%=0,2-0,8) e uma razão de prevalência 90% menor de ≥150% da necessidade de energia estimada (RP=0,1; IC95%=0,02-0,3) quando comparados à queles com ausência dessa mutação. Modelo ajustado para função pulmonar, necessidade de energia estimada e índice de massa corporal. Conclusão Pacientes portadores da mutação delta F508 apresentaram um menor percentil de índice de massa corporal e menor consumo calórico diário quando comparados à queles sem a mutação. .

ABSTRACT

O diabetes melito tipo 1 (DM1) está associado ao desenvolvimento de complicações crônicas de elevada morbi-mortalidade em indivíduos jovens em idade produtiva. A terapia intensiva com insulina comprovadamente diminui o aparecimento das complicações crônicas da doença. Entretanto, essa terapia ainda está associada ao aumento da incidência de hipoglicemia. Em pacientes com “DM1 lábil”, os quais apresentam hipoglicemias graves sem sintomas de alerta, o transplante de ilhotas pancreáticas humanas é uma das melhores alternativas para restaurar a secreção de insulina e a percepção da hipoglicemia. Cerca de 80% dos pacientes que receberam transplante de ilhotas de mais de um doador, submetidos ao tratamento imunossupressor do protocolo de Edmonton, adquiriram independência de insulina após 1 ano do transplante. Porém, apenas 10% destes pacientes permaneceram livres de insulina após 5 anos. Entretanto, mesmo aqueles pacientes que necessitaram utilizar novamente insulina tiveram a normalização da homeostase glicêmica e da percepção da hipoglicemia, com prevenção da hipoglicemia grave. Sendo assim, o transplante de ilhotas é capaz de diminuir os níveis de glicose plasmática e HbA1c, reduzir a ocorrência de hipoglicemias graves e melhorar a qualidade de vida dos pacientes. O objetivo deste artigo foi fazer uma breve revisão da literatura sobre o isolamento e transplante de ilhotas pancreáticas humanas e relatar a implantação de um laboratório de isolamento de ilhotas humanas no Serviço de Endocrinologia do Hospital de Clínicas de Porto Alegre.


Type 1 diabetes mellitus (DM1) is associated with chronic complications of high morbidity and mortality in young adults in a productive age. Insulin therapy has proved to reduce the chronic complications of diabetes. However, this therapy is still associated to an increased incidence of hypoglycemia. In patients with “brittle DM1”, who have severe hypoglycemia without any symptoms (hypoglycemia unawareness), the pancreatic islet transplantation is one of the best alternatives for restoring insulin secretion and hypoglycemia perception. About 80% of the patients who received islet transplantation from more than one donor, on immunosuppressive treatment with the Edmonton’s protocol, maintained insulin independence 1 year after transplantation. Nevertheless, only 10% of these patients remained free of insulin after 5 years post-transplantation. However, even those patients who returned to insulin treatment had a normalization of the glucose homeostasis and hypoglycemia perception. Therefore, islet transplantation is able to diminish plasmatic glucose and HbA1c levels, to reduce the occurrence of severe hypoglycemia, and to improve the quality of life of the patients. The purpose of this paper is to briefly review islet isolation and transplantation process, and report the establishing of a human islet isolation laboratory in the Endocrine Service at Hospital de Clínicas de Porto Alegre.

ABSTRACT

A genômica nutricional avalia o efeito da variação genética na interação entre dieta e doenças crônicas. O objetivo deste manuscrito foi revisar os principais polimorfismos associados à obesidade, ao diabetes melito e também aos fatores da dieta. As principais interações entre polimorfismos genéticos e dieta foram: para obesidade: interleucina-6 (IL-6) com consumo energético; receptor ativado por proliferador de peroxissoma gama 2 (PPAR-gama2) e fat mass and obesity associated (FTO) com consumo de gorduras; receptor β-adrenérgico 2 (ADRB2) e receptor da melanocortina-4 (MCR4) com consumo de carboidratos; para perda de peso: proteínas desacopladoras (UCPs) com restrição calórica; para leptinemia: receptor da leptina (LEPR) com restrição calórica; para diabetes melito: PPAR-gama2 com consumo de gordura; para hipertrigliceridemia: proteína transportadora de ácidos graxos 2 (FABP2) com consumo de gordura. Os dados apresentados sugerem que a genômica nutricional é importante ao desenvolvimento da obesidade e do diabetes melito.


Nutritional genomics evaluates the effects of genetic variation in the interaction between diet and chronic diseases. The aim of this manuscript was to review the most important genetic polymorphisms associated with obesity, diabetes mellitus, and dietary factors. The main interactions among genetic polymorphisms and diet were: for obesity: interleukin-6 (IL-6) with daily intake; peroxisome proliferator-activated receptor gamma 2 (PPAR-gama2) and fat mass and obesity associated (FTO) with fat intake; β-adrenergic receptor 2 (ADRB2) and melanocortin receptor 4 (MCR4) with carbohydrate intake; or reduction in body weight: uncoupling proteins (UCPs) with restriction of energy; for leptinemia: leptin receptor (LEPR) with restriction of energy; for diabetes mellitus: PPAR-gama2 with fat intake; for hypertriglyceridemia: fatty acid-binding protein 2 (FABP2) with fat intake. The data demonstrated suggest that nutritional genomics is important for the development of obesity and diabetes mellitus.

ABSTRACT

O controle glicêmico intensificado pode prevenir e/ou retardar o aparecimento das complicações crônicas do diabetes melito (DM). O carboidrato da dieta é o principal determinante da glicemia pós-prandial, sendo o índice glicêmico (IG) e a carga glicêmica úteis para prever a resposta glicêmica aos alimentos. O objetivo deste manuscrito foi revisar criticamente o papel das dietas de baixo IG na prevenção e controle metabólico do diabetes melito tipo 2 (DMT2). O risco para desenvolvimento de DMT2 com dietas de alto IG variou de 1,21 a 1,59. A redução de 12 a 32 unidades no IG da dieta diminuiu em 0,39 a 0,50 pontos percentuais a HbA1c. Os efeitos dessas dietas no perfil lipídico e peso corporal no DMT2 permanecem controversos. Em conclusão, as evidências atuais indicam que a incorporação do IG no planejamento dietético de pacientes com DMT2 contribui para a melhora do controle glicêmico.


The tight glycemic control can prevent and/or delay the development of chronic complications of diabetes mellitus (DM). Dietary carbohydrates are the main determinant of postprandial blood glucose and glycemic index (GI) and glycemic load are used to predict blood glucose response to foods. The aim of this paper was to critically review the role of low GI diets in type 2 diabetes mellitus (T2DM) prevention and metabolic control. The risk for development of T2DM with high GI diets ranged from 1.21 to 1.59.The reduction from 12-32 units in the GI of diets decreased 0.39-0.50 percent in HbA1c values. However, the effects of these diets on lipid profile and body weight in patients with T2DM remain controversial. In conclusion, the current evidence indicates that the inclusion of GI in the dietary planning for patients with T2DM contributes to the improvement of glycemic control.

ABSTRACT

O papel da dieta na síndrome metabólica (SM) tem sido estudado em relação a cada um de seus componentes: obesidade, níveis pressóricos elevados, dislipidemia e alterações no metabolismo da glicose. Entretanto, poucos estudos avaliaram os efeitos da dieta na presença da SM como uma entidade clínica independente. O objetivo deste manuscrito foi revisar a importância dos fatores dietéticos e as recomendações dietoterápicas na SM. Estudos recentes demonstraram que o consumo de grãos integrais foi associado negativamente com SM. Já alimentos com alto índice glicêmico foram associados positivamente com resistência à insulina e prevalência de SM. O seguimento de uma dieta mediterrânea foi capaz de reduzir o número de componentes da SM. Também a adoção da dieta DASH melhorou o perfil de todos os componentes da SM. Recomenda-se, para pacientes com SM, um valor energético total compatível com a obtenção e/ou manutenção do peso corporal desejável. O conteúdo de gordura, em especial o consumo de gordura saturada, e colesterol deve ser reduzido e o consumo de grãos integrais, frutas e vegetais, aumentado. Provavelmente as fibras alimentares têm um papel importante no manejo dietoterápico da SM. Novos estudos que avaliem o papel da dieta na presença e no desenvolvimento da SM são necessários.


The role of diet in metabolic syndrome (MS) has been studied regarding each one of its components: obesity, high blood pressure, dyslipidemia, and abnormal glucose metabolism. However, few studies evaluated the effects of diet in the presence of MS as a unique independent disease. The aim of this manuscript was to review the role of dietary factors and dietary recommendations for MS. Recently some studies demonstrated that intake of whole-grain foods were negatively associated with MS. Foods with high glycemic index were positively associated with insulin resistance and the prevalence of MS. Following a Mediterranean-style diet caused a reduction in the number of MS components. Also, the adoption of the DASH diet improved the profile of all MS components. A total daily energy intake to obtain and/or to maintain a desirable weight is recommended for patients with MS. The fat content, especially from saturated fat, and cholesterol must be reduced and the intake of whole-grain foods, fruits, and vegetables must be increased. Probably, dietary fibers have an important role in the management of MS. New studies to evaluate the role of diet in the presence and development of MS are needed.
