| 1 | Assessment of resting energy expenditure in patients with cirrhosis显示文摘BACKGROUND Malnutrition affects 20%to 50%of patients with cirrhosis.It may be associated with serious complications and has a direct impact on prognosis.Resting energy expenditure(REE)is an important parameter to guide the optimization of therapy and recovery of nutritional status in patients with cirrhosis.However,the REE of patients with cirrhosis is still unclear,casting doubt upon the optimal nutritional management approach.AIM To identify the best method that predicts the REE of cirrhotic patients,using indirect calorimetry(IC)as the gold standard.METHODS An observational study was performed on 90 patients with cirrhosis.REE was assessed by IC,bioelectrical impedance analysis(BIA),and predictive formulas,which were compared using Bland-Altman plots and the Student’s t-test.RESULTS REE values measured by IC(1607.72±257.4 kcal)differed significantly from those determined by all other methods(BIA:1790.48±352.1 kcal;Harris&Benedict equation:2373.54±254.9 kcal;IOM equation:1648.95±185.6 kcal;Cunningham equation:1764.29±246.2 kcal),except the Food and Agriculture Organization of the United Nations,World Health Organization,and United Nations University(FAO/WHO/UNU)(1616.07±214.6 kcal)and McArdle(1611.30±241.8 kcal)equations.We found no significant association when comparing IC and 24-h dietary recall among different Child-Pugh classes of cirrhosis.CONCLUSION The IOM and FAO/WHO/UNU equations have the best agreement with the CI.These results indicate a possibility of different tools for the clinical practice on cirrhotic patients. | Shaiane Ferreira Cláudio Augusto Marroni Jessica Taina Stein Roberta Rayn Ana Cristhina Henz Natália P Schmidt Randhall B Carteri Sabrina Alves Fernandes | 2022 | World Journal of Hepatology2022，14，4： | 0 |
| 2 | Resting energy expenditure in cirrhotic patients with and without hepatocellular carcinoma显示文摘BACKGROUND The diagnosis of malnutrition in patients with independent hepatocellular carcinoma(HCC)varies from 20%to 50%,is related to important complications and has a direct impact on the prognosis.Determination of the resting energy expenditure(REE)has become an important parameter in this population,as it allows therapeutic adjustments to recover their nutritional status.The REE in cirrhosis,with and without HCC,is not clearly defined,and requires the identification and definition of the best nutritional approach.AIM To evaluate the REE of patients with cirrhosis,with and without HCC.METHODS This is a prospective observational study evaluating the REE of 118 patients,33 with cirrhosis and hepatocellular carcinoma and a control group of 85 patients with cirrhosis without HCC,using indirect calorimetry(IC),bioimpedance,and predictive formulas.RESULTS The REE determined by IC in cirrhotic patients with HCC was 1643±364 and in those without HCC was 1526±277(P=0.064).The REE value as assessed by bioimpedance was 1529±501 for those with HCC and 1660±385 for those without HCC(P=0.136).When comparing the values of REE determined by IC and predictive formulas in cirrhotics with HCC,it was observed that only the formulas of the Food and Agriculture Organization(FAO)/World Health Organization(WHO)(1985)and Cunningham(1980)presented values similar to those determined by IC.When comparing the REE values determined by IC and predictive formulas in cirrhotics without HCC,it was observed that the formulas of Schofield(1985),FAO/WHO(1985),WHO(2000),Institute of Medicine(IOM)(2005)and Katch and McArdie(1996)presented values similar to those determined by IC.CONCLUSION The FAO/WHO formula(1985)could be used for cirrhotic patients with or without HCC;as it is the one with the values closest to those obtained by IC in these cirrhotic patients. | Ana Cristhina Henz Claudio Augusto Marroni Daniella Miranda da Silva Joise Munari Teixeira ThiagoThoméSilveira Shaiane Ferreira Andresa ThoméSilveira Natalia Perin Schmidt Jessica Taina Stein Roberta Goulart Rayn Sabrina Alves Fernandes | 2021 | World Journal of Gastrointestinal Pharmacology and Therapeutics2021，12，1： | 0 |
