ABSTRACT
CONTEXT: There is growing evidence that insufficient dietary intake is associated with sarcopenia. OBJECTIVE: In this systematic review and meta-analysis, the energy and nutrient intakes by people with and without sarcopenia were compared using only the European Working Group on Sarcopenia in Older People 2010 (EWGSOP1) and 2019 (EWGSOP2) consensus diagnostic criteria. DATA SOURCES: Only observational studies that compared energy and nutrient intake from food alone by individuals with and without sarcopenia were included. Studies were searched in the following databases: Embase, PubMed, Scopus, Web of Science, Lilacs, Ovid, and Scopus. The review followed the PRISMA checklist and submitted the protocol to PROSPERO. DATA EXTRACTION: Data were extracted by 2 authors independently. The methodological quality of the studies was assessed using the Newcastle-Ottawa scale. DATA ANALYSIS: A total of 8648 articles were identified and 12 were selected. Among individuals with sarcopenia, lower intakes of energy and some nutrients, mainly with antioxidant properties, were observed compared with those without sarcopenia. Meta-analyses showed that individuals with sarcopenia consume fewer calories/day than individuals without sarcopenia (n = 10 studies; standardized mean difference (SMD) -0.15; 95% confidence interval: -0.29, -0.01) diagnosed by EWGSOP1 and EWGSOP2. Individuals with sarcopenia consume less omega-3, folate, magnesium, phosphorus, selenium, zinc, and vitamins C, D, and E when compared with those without sarcopenia. CONCLUSION: The results of the present study suggest that insufficient intake of energy and nutrients with antioxidant potential may be associated with sarcopenia. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD 42020195698.
ABSTRACT
BACKGROUND: Sarcopenia is a clinical condition associated with several liver diseases and it includes non-alcoholic fatty liver disease (NAFLD) in its broad spectrum as steatosis, steatohepatitis and fibrosis. However, the criteria to define sarcopenia are diverse, and even those established in consensus have been discussed regarding their performance in making an accurate diagnosis. AIM: To evaluate the prevalence of sarcopenia, using different methods, in patients with NAFLD, and its association with clinical-anthropometric parameters. METHODS: This was an observational study of outpatients with NAFLD. Sarcopenia was defined by the European Working Group Consensus on Sarcopenia in Older People of 2010 (EWGSOP1) and 2018 (EWGSOP2). The skeletal muscle index was used to estimate muscle mass, handgrip strength was assessed using the dynamometer and physical performance by walking a distance of four meters at usual walking speed. The non-invasive fibrosis scores, fibrosis-4 (FIB-4) index and Aspartate aminotransferase to platelet ratio index (APRI), were used to assess the absence and presence of fibrosis. RESULTS: Fifty-seven individuals with NAFLD were evaluated, the mean age (SD) was 52.7 (11.3) years and 75.4% were female. Fibrosis assessed by FIB-4 and APRI was observed in 3.7% and 16.6% of patients with NAFLD, respectively. The diagnosis of sarcopenia was identified only by EWGSOP1 in 3.5% of NAFLD patients, and the prevalence of probable/pre-sarcopenia was higher using the EWGSOP2 consensus at 26.3%, when compared to 1.8% with EWGSOP1. Sarcopenia defined by EWGSOP1, was associated with grade I steatosis, but without overweight (P < 0.05). An association between sarcopenia and fibrosis was not observed (P > 0.05). EWGSOP2 showed a greater number of patients with probable sarcopenia, and who were overweight (12 (80.0%)), with a higher degree of steatosis [11 (73.3%) and presence of fibrosis (1 (6.7%), FIB-4 and 3 (20.0%), APRI] compared to EWGSOP1 [1 (100%), 0 (0.0%), 0 (0.0%), FIB-4 and 0 (0.0%), APRI, respectively]. CONCLUSION: The present study showed that sarcopenia in NAFLD was not predominant in patients without fibrosis, by both diagnostic methods. In addition, the prevalence of probable sarcopenia also depends on the method applied.
ABSTRACT
BACKGROUND: Supplementation with probiotics, prebiotics and symbiotics has shown positive effects on clinical markers and risk factors for non-alcoholic fatty liver disease (NAFLD). OBJECTIVE: To evaluate the effect of supplementation with probiotic, prebiotic or symbiotic on intestinal microbiota in NAFLD patients. METHODS: Two investigators conducted independently search for articles in the Medline databases, via PubMed, Web of Science, Embase, Scopus, Lilacs, Central Cochrane Library, Clinical Trials.gov and on the Ovid platform for the gray literature search. RESULTS: A total of 3,423 papers were identified by searching the electronic databases; 1,560 of them were duplicate and they were excluded; 1,825 articles were excluded after reading the title and abstract. A total of 39 articles were select to reading, however only four articles met the eligibility criteria to include in this systematic review. Three of the included studies that used prebiotic or symbiotic supplementation showed that after the intervention there were changes in the intestinal microbiota pattern. Only in one study such changes were not observed. A high risk of bias was observed in most assessments. CONCLUSION: Although there is a possible change in the gut microbiota of individuals with NAFLD after supplementation with symbiotics or prebiotics, a clinical indication as part of NAFLD treatment is not yet possible.

RESUMO Contexto A suplementação com probióticos, prebióticos e simbióticos mostrou efeitos positivos sobre marcadores clínicos e fatores de risco para doença hepática gordurosa não alcoólica (DHGNA). Objetivo Avaliar o efeito da suplementação com probióticos, prebióticos ou simbióticos na microbiota intestinal em pacientes com DHGNA. Métodos Dois pesquisadores realizaram buscas independentes de artigos nas bases de dados Medline, via PubMed, Web of Science, Embase, Scopus, Lilacs, Biblioteca Central Cochrane, Clinical Trials.gov e na plataforma Ovid para busca de literatura cinza. Os títulos e resumos foram lidos para excluir artigos irrelevantes. Em seguida, os artigos selecionados foram lidos na íntegra e avaliados de acordo com os critérios de elegibilidade. O risco de viés foi avaliado de acordo com a Cochrane. Resultados Um total de 3.423 artigos foram identificado por meio de busca nas bases de dados eletrônicas; 1.560 deles eram duplicados e foram excluídos; 1.825 artigos foram excluídos após a leitura do título e do resumo. Um total de 39 artigos foram selecionado para leitura, porém apenas quatro artigos atenderam aos critérios de elegibilidade para inclusão nesta revisão sistemática. Três dos estudos incluídos que utilizaram suplementação de prebióticos ou simbióticos mostraram que após a intervenção ocorreram mudanças no padrão da microbiota intestinal. Apenas em um estudo tais mudanças não foram observadas. Um elevado risco de viés foi observado na maioria das avaliações. Conclusão Embora haja uma possível alteração na microbiota intestinal de indivíduos com DHGNA após a suplementação com simbióticos ou prebióticos, uma indicação clínica como parte do tratamento da DHGNA ainda não é possível.
ABSTRACT
OBJECTIVE: This study aims to evaluate the role of anthropometric clinical indicators of visceral adiposity as predictors of NAFLD, identifying the cutoff points based on gender. METHODS: This was a cross-sectional study conducted in patients with or without NAFLD. Waist circumference (WC), body mass index (BMI), waist-to-height ratio (WHtR), Conicity Index (C Index), and lipid accumulation product (LAP) were evaluated. RESULTS: A total of 107 individuals were evaluated, of which 46.7% were diagnosed with NAFLD. Individuals with NAFLD presented higher values of WC, BMI, C Index, LAP, and WHtR when compared with those without NAFLD (p<0.05). For the total sample, the indicators WC, BMI, WHtR, LAP, and C Index had an area under the receiver operator characteristic curve (AUC) above 0.87, with no difference in the prediction of NAFLD in both sexes. WHtR (AUC=0.934) was the indicator of visceral adiposity with the best discriminatory power for NAFLD, followed by LAP (0.919), WC (0.912), C Index (0.907), and BMI (0.877). CONCLUSIONS: The anthropometric clinical indicators of visceral adiposity showed high performance, especially the WHtR indicator, as NAFLD predictors.

The objective was to critically analyze studies that evaluated the predictive capacity of indicators of visceral adiposity in non-alcoholic fatty liver disease (NAFLD). The bibliographic research was carried out using the electronic database PubMed, LILACS and SciELO, references of selected articles. Although we found few studies, they have already used several indicators of visceral adiposity as waist circumference, waist-to-hip ratio, waist-to-height ratio, Lipid accumulation product, Body Shape Index, Body Roundness Index and most them were good predictors of NAFLD. Thus, the anthropometric indicators may contribute for the diagnosis of NAFLD in a simple, low-cost and non-invasive way, allowing early therapeutic measures to prevent the evolution to non-alcoholic steatohepatitis.
ABSTRACT
Introduction: Calcium deficiency is considered a risk factor for the development of osteoporosis in inflammatory bowel disease (IBD) patients. Various dietary restrictions, including milk products are reported by these patients. Objective: To evaluate dairy product and dietary calcium intake by IBD patients. Methods: This cross-sectional study enrolled 65 outpatients with IBD recruited from one reference center for IBD. Asemi-structured questionnaire (to collect demographic, socioeconomic and clinical data) and a quantitative food frequency questionnaire were administered. With regard to clinical data, we evaluated the anthropometric nutritional status, the disease classification, the disease activity index and the presence of gastrointestinal symptoms. Self reported modifications in the use of dairy products were evaluated. Results: The IBD patients ages ranged from 20-75years and 67.0% were diagnosed with ulcerative colitis. The majority (64.7%) reported restricting dairy products. The frequency of gastrointestinal symptoms was higher among the Crohns disease patients who restricted dairy products than among those with no restrictions (100%vs 42.9%; p = 0.013); this result was not observed among the UC (ulcerative colitis) patients. Disease activity was also more frequent in the IBD patients who restricted dairy products than in those with no restrictions (23.8%vs 4.5%; p = 0.031), and among the UC patients, extensive disease was more common in the patients who restricted dairy products than in those with no restrictions (42.9%vs 20.0%; p = 0.03).Conclusion: Restricting dairy products is common among IBD patients, possibly due to disease activity, the presence of gastrointestinal symptoms and the extension of the disease (AU)
Introducción: Se considera que la deficiencia de calcio es un factor de riesgo para el desarrollo de osteoporosis en pacientes con enfermedad inflamatoria intestinal (EII). En estos pacientes se han notificado diversas restricciones dietéticas. Objetivo: Evaluar la ingesta de productos lácteos y calcio de la dieta en pacientes con EII. Métodos: En este estudio cruzado se reclutaron 65 pacientes ambulatorios con EII procedentes de un centro de referencia para EII. Se administraron un cuestionario semi-estructurado (que recogía datos demográficos, socio-económicos y clínicos) y un cuestionario de frecuencia de consumo de alimento. Con respecto a los datos clínicos, evaluamos el estado nutricional antropométrico, la clasificación de la enfermedad, el índice de actividad de la enfermedad y la presencia de síntomas gastrointestinales. Se evaluaron las modificaciones auto-notificadas en el uso de los productos lácteos. Resultados: Las edades de los pacientes con EII variaban entre los 20 y 75 años y el 67,0% fueron diagnosticados de colitis ulcerosa. La mayoría (64,7 %) notificaban una restricción de los productos lácteos. La frecuencia de síntomas gastrointestinales fue mayor en los pacientes con enfermedad de Crohn que restringían los productos lácteos que en aquellos que no lo hacían (100% frente a 42,9%; p = 0,013); este resultado no se observó en los pacientes con colitis ulcerosa CU. La actividad de la enfermedad también fue más frecuente en los pacientes con EII que restringían los productos lácteos que en aquellos sin restricción (23,8% frente a 4,5%; p = 0,031) y, en los pacientes con CU, la enfermedad extensa fue más habitual en pacientes que restringían los productos lácteos que en aquellos que no lo hacían (42,9 % frente a 20,0%; p = 0,03). Conclusión: La restricción de productos lácteos es habitual en pacientes con EII, posiblemente debido a la actividad de la enfermedad, la presencia de síntomas gastrointestinales y la extensión de la enfermedad (AU)
