RESUMO
INTRODUCTION: The Healthy Eating Index (HEI) is a comprehensive measure to assess diet quality. Because of the various factors that influence the nutritional status of older adults, there is a need to adapt an index that assesses the quality of the diet considering the dietary requirements of aging and health promotion. This study aimed to adapt the HEI for older adults, considering their needs for healthy eating. METHODS: Food consumption data was collected by means of three non-consecutive 24-hour food recalls (R24h). For the adaptation of the Healthy Eating Index for Older Adults (HEI-OA), the components and scoring methodology of HEI-2015 were maintained and Brazilian food intake recommendations for the older population were used, which are in line with international recommendations. The validity of the HEI-OA was assessed by four ideal diets, Mann-Whitney's test, Spearman's correlation analysis and Cronbach's coefficient. RESULTS: Content validity of the HEI-OA was confirmed by the maximum score for diets recommended to older adults and by the score between groups with known differences in diet quality. The HEI-OA total score did not correlate with total energy intake (TEI - total energy value: r = -0.141, p > 0.05). The total HEI-OA score showed a statistically significant correlation with several nutrients. These correlations allowed identifying that these nutrients are closely related to the components of the HEI-OA. The internal consistency value for the HEI-OA total score was 0.327, similar to the 2005 and 2010 versions of the HEI. CONCLUSION: The HEI was successfully adapted for use with older adults, presenting validity and reliability. The HEI-OA can be used to assess diet quality in line with international dietary guidelines for healthy aging.

BACKGROUND: Promising results in improvement of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH) have been identified following probiotic (PRO) treatment. OBJECTIVES: To evaluate PRO supplementation on hepatic fibrosis, inflammatory and metabolic markers, and gut microbiota in NASH patients. METHODS: In a double-blind, placebo-controlled clinical trial, 48 patients with NASH with a median age of 58 y and median BMI of 32.7 kg/m2 were randomly assigned to receive PROs (Lactobacillus acidophilus 1 × 109 colony forming units and Bifidobacterium lactis 1 × 109 colony forming units) or a placebo daily for 6 mo. Serum aminotransferases, total cholesterol and fractions, C-reactive protein, ferritin, interleukin-6, tumor necrosis factor-α, monocyte chemoattractant protein-1, and leptin were assessed. To evaluate liver fibrosis, Fibromax was used. In addition, 16S rRNA gene-based analysis was performed to evaluate gut microbiota composition. All assessments were performed at baseline and after 6 mo. For the assessment of outcomes after treatment, mixed generalized linear models were used to evaluate the main effects of the group-moment interaction. For multiple comparisons, Bonferroni correction was applied (α = 0.05/4 = 0.0125). Results for the outcomes are presented as mean and SE. RESULTS: The AST to Platelet Ratio Index (APRI) score was the primary outcome that decreased over time in the PRO group. Aspartate aminotransferase presented a statistically significant result in the group-moment interaction analyses, but no statistical significance was found after the Bonferroni correction. Liver fibrosis, steatosis, and inflammatory activity presented no statistically significant differences between the groups. No major shifts in gut microbiota composition were identified between groups after PRO treatment. CONCLUSIONS: Patients with NASH who received PRO supplementation for 6 mo presented improvement in the APRI score after treatment. These results draw attention to clinical practice and suggest that supplementation with PROs alone is not sufficient to improve enzymatic liver markers, inflammatory parameters, and gut microbiota in patients with NASH. This trial was registered at clinicaltrials.gov as NCT02764047.

OBJECTIVE: To compare the effect of two programs of Food and Nutrition Education (FNE) on the Nutrition knowledge of elderly women, Brazil. METHODS: Randomized field trial. Community-based elderly women over 60 years (n = 36) participated in a twelve-week intervention in either of two FNE programs: Psychopedagogical Program (PP) or Culinary Workshop Program (CWP). There were three moments of data collection in the study; pre-intervention knowledge data); post intervention and follow up (after 6 months upon intervention completion). A questionnaire about knowledge of food and Nutrition was administered at every data collection moment. RESULTS: In the analysis performed by the Generalized Estimation Equation Models (GEE) there was a significant interaction effect (P = 0.033) in the diabetes block in which the percentage of correct answers in the follow-up moment was higher compared to the pre-intervention moment in the CWP group (65.65% and 45.66%, respectively). In the knowledge blocks: total percentage of correct answers, hypertension, food processing, the evaluation effect was observed, regardless of the intervention performed.Three blocks of knowledge, including the block of the total percentage of correct answers in knowledge in Nutrition, presented a significant evaluation effect, which suggests that the interventions were important for the gain of knowledge, regardless of the type of intervention performed. Elderly-focused FNE programs should include a methodology that encompasses recreational education activities, and practical activities, such as culinary workshops.
RESUMO
Objective: To demonstrate the correlations of the diagnostic criteria for sarcopenia and the levels of Non-alcoholic Fat Liver Disease (NAFLD) assessed by liver biopsy in a physically active population. Methods: Cross-sectional study. Individuals aged >18 years, with NAFLD confirmed by liver biopsy, physically active. Sarcopenia assessment followed EWGSOP2: muscle strength by handgrip, Skeletal Muscle Mass by Bioimpedance, and physical performance by usual gait speed. Statistical Analysis: To test differences between groups in continuous variables, Student's T or Mann-Whitney U Test for independent samples. Pearson and Spearman tests were used for correlations. A 5% significance was considered (p<0.05). Results: 52 patients with NAFLD included, consisting of 35 women and 15 men. There was no difference in age or anthropometric variables. Were found difference statically significant in platelets (higher in women), basal insulin, HOMA-IR and Quick (higher in men). In sarcopenia, the handgrip strength showed difference in favors of men. There was no statistically significant correlation between the sarcopenia and NAFLD levels. Discussion: sarcopenia has been reported as an independent risk factor for NAFLD and its progressions. The physical exercise is one of the most recommended and more effective treatment for both conditions, so is expected that a non-sedentary individual can reduce both indicators. However, there is no consensus about the best method. Also, the both conditions share heterogeneity in diagnosis, prognosis, reason for develop and risk factors across the literature. Conclusion: For populations where most individuals are physically active, it is not possible to find correlation between sarcopenia diagnostic criteria and the stages of NAFLD.
Objetivo: Demonstrar as correlações dos critérios diagnósticos de sarcopenia e dos níveis de doença hepática gordurosa não alcoólica (DHGNA) avaliados por biópsia hepática em uma população fisicamente ativa. Métodos: Estudo transversal. Indivíduos com idade >18 anos, com DHGNA confirmada por biópsia hepática, fisicamente ativos. A avaliação da sarcopenia seguiu o EWGSOP2: força muscular por preensão manual, massa muscular esquelética por bioimpedância e performance física por velocidade usual de marcha. Análise Estatística: Para testar diferenças entre grupos nas variáveis contínuas, teste T de Student ou Teste U de Mann-Whitney para amostras independentes. Os testes de Pearson e Spearman foram utilizados para correlações. Foi considerada significância de 5% (p<0,05). Resultados: Foram incluídos 52 pacientes com DHGNA, sendo 35 mulheres e 15 homens. Não houve diferença na idade ou nas variáveis antropométricas. Foram encontradas diferenças estatisticamente significativas em plaquetas (maior em mulheres), insulina basal, HOMA-IR e Quick (maior em homens). Na sarcopenia, a força de preensão manual apresentou diferença em favor dos homens. Não houve correlação estatisticamente significativa entre os níveis de sarcopenia e DHGNA. Discussão: a sarcopenia tem sido relatada como fator de risco independente para DHGNA e suas progressões. O exercício físico é um dos tratamentos mais recomendados e mais eficazes para ambas as condições, pelo que se espera que um indivíduo não sedentário consiga reduzir ambos os indicadores. No entanto, não há consenso sobre o melhor método. Além disso, ambas as condições compartilham heterogeneidade no diagnóstico, prognóstico, razão de desenvolvimento e fatores de risco em toda a literatura. Conclusão: Para populações onde a maioria dos indivíduos é fisicamente ativo, não é possível encontrar correlação entre os critérios diagnósticos de sarcopenia e os estágios da DHGNA.
Objetivo: demostrar las correlaciones de los criterios diagnósticos de sarcopenia y los niveles de enfermedad del hígado graso no alcohólico (EHGNA) evaluados mediante biopsia hepática en una población físicamente activa. Métodos: Estudio transversal. Individuos mayores de 18 años, con EHGNA confirmada mediante biopsia hepática, físicamente activos. La evaluación de la sarcopenia siguió el EWGSOP2: fuerza muscular mediante agarre manual, masa muscular esquelética mediante bioimpedancia y rendimiento físico mediante velocidad de marcha habitual. Análisis estadístico: Para probar diferencias entre grupos en variables continuas, prueba T de Student o U de Mann-Whitney para muestras independientes. Para las correlaciones se utilizaron las pruebas de Pearson y Spearman. Se consideró una significancia del 5% (p<0,05). Resultados: Se incluyeron 52 pacientes con EHGNA, 35 mujeres y 15 hombres. No hubo diferencia en la edad ni en variables antropométricas. Se encontraron diferencias estadísticamente significativas en plaquetas (mayor en mujeres), insulina basal, HOMA- IR y Quick (mayor en hombres). En la sarcopenia, la fuerza de prensión manual mostró diferencia a favor de los hombres. No hubo correlación estadísticamente significativa entre la sarcopenia y los niveles de NAFLD. Discusión: la sarcopenia ha sido reportada como un factor de riesgo independiente para NAFLD y sus progresiones. El ejercicio físico es uno de los tratamientos más recomendados y efectivos para ambas afecciones, por lo que se espera que una persona no sedentaria pueda reducir ambos indicadores. Sin embargo, no hay consenso sobre cuál es el mejor método. Además, ambas afecciones comparten heterogeneidad en el diagnóstico, pronóstico, motivo de desarrollo y factores de riesgo en la literatura. Conclusión: Para poblaciones donde la mayoría de las personas son físicamente activas, no es posible encontrar correlación entre los criterios de diagnóstico de sarcopenia y las etapas de NAFLD.
RESUMO
BACKGROUND: Social networks have been pointed out as 1 of the greatest means of spreading information. A large part of the population is already present on these platforms, looking up subjects such as health, nutrition, and food. To reach this audience, it may be important for dietitians to explore social networks. However, there is a gap in scientific studies on exploring the ways in which these platforms are used by dietitians in Brazil, and the roles they play in the profession have not been well defined. OBJECTIVE: This study aims to describe the roles that social networks play in dietitians' practice in Brazil and their mode of use of social networks. This study also aims to identify professionals' perceptions and opinions regarding the use of these tools, as well as changes in behavior on social network usage caused by the COVID-19 pandemic. METHODS: We carried out a quantitative cross-sectional study, collecting data through an online questionnaire, submitted between October 2020 and January 2021 to dietitians registered on the Federal Council of Dietitians. All participants included in the study answered questions about the use of social networks in their professional context. RESULTS: In total, 264 (91.7%) of the 288 participants reported using social networks for professional practice. Instagram was the social network most often used by professionals (224/264, 84.8%). Dietitians (N=288) related to the use of social networks (always to almost always) for sharing information about their services (n=114-72 [39.6%-25%], respectively), following the work of other dietitians (n=172-64 [59.7%-22.2%], respectively), and writing about topics related to food and nutrition (n=166-53 [57.6%-18.4%], respectively). The roles played by social networks in the professional context of dietitians were attracting more clients (210/289, 72.7%) and keeping in touch with them (195/289, 67.5%). Furthermore, 227 (78.5%) of the 289 dietitians strongly agreed that social networks are good tools to promote their services. During the COVID-19 pandemic, 216 (74.7%) of the 289 participants noticed changes in their behavior, feelings, or beliefs on the use of social networks related to professional practice, and 149 (51.6%) have increased the frequency of sharing information about nutrition and health in general on social networks. CONCLUSIONS: The main roles of social networks in the professional context of dietitians are to attract clients and to facilitate the contact between professional and client. The modes of use reported by the professionals included sharing information about their services, following the work of professional colleagues, and writing about topics related to nutrition. Most of them reported believing that social networks are an effective way to disseminate their services. Moreover, most professionals claimed to have noticed changes in their behaviors or beliefs on social media during the COVID-19 pandemic.
RESUMO
BACKGROUND: To evaluate the performance of a non-invasive test (Fibromax™, Ferring Pharmaceutical, Saint-Prex, Switzerland) and inflamatory markers (IL-1ß, IL-6, IL-8, TNF-α, MCP-1) in the diagnosis and staging of patients with non-alcoholic fatty liver disease. METHODS: Patients older than 18 years with steatosis were prospectively evaluated at a tertiary hospital in southern Brazil. Liver biopsy, Fibromax™ test and inflamatory markers (IL-1ß, IL-6, IL-8, TNF-α, MCP-1) were performed. Measures of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were used, considering liver biopsy as the gold standard. RESULTS: Seventy-three Fibromax™ tests were analyzed. SteatoTest presented a sensitivity of 95.5% and PPV of 97.0% for the diagnosis of steatosis. NashTest obtained a sensitivity of 83.3%, specificity of 37.5%, PPV of 90.9% and NPV of 23.1% for the diagnosis of non-alcoholic steatohepatitis (NASH). FibroTest presented a sensitivity of 38.9%, specificity of 92.7%, PPV of 63.6% and NPV of 82.3% to evaluate advanced fibrosis. In the evaluation of patients with grade 2 and 3 steatosis, ROC analyses showed an area under the curve (AUROC) for SteatoTest of 0.68 (P=0.015). NashTest AUROC was 0.59 (P=0.417) for the evaluation of NASH. FibroTest AUROC was 0.79 (P<0.001) for advanced fibrosis. Kappa coefficient values for SteatoTest, NashTest and FibroTest were not statistically significant. Thirty-seven patients performed also analysis of the inflamatory markers, showing that patients with inflammatory activity grade 2-3 on liver biopsy had significantly higher levels of IL6 (P=0.016) and lower TNF-α (P=0.034), but there was no other difference when analysed fibrosis or steatosis. CONCLUSIONS: The Fibromax™ test and the inflamatory markers (IL-1ß, IL-6, IL-8, TNF-α, MCP-1) did not present a satisfactory performance to be considered a good alternative to replace liver biopsy in the evaluation of non-alcoholic fatty liver disease.

INTRODUCTION AND AIM: The gold-standard for fibrosis diagnosis in non-alcoholic fatty liver disease (NAFLD) is liver biopsy, despite its invasive approach, sampling limitations and variability among observers. The objective was to validate the performance of non-invasive methods (Fibroscan™; APRI, FIB4 and NAFLD score) comparing with liver biopsy in the evaluation of liver fibrosis in patients with NAFLD. MATERIAL AND METHODS: NAFLD patients ≥18 years of age who were submitted to liver biopsy were included and evaluated at two reference tertiary hospitals in Brazil with transient hepatic elastography (THE) assessment through Fibroscan™, APRI, FIB4 and NAFLD scores were determined. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values for the diagnosis of advanced fibrosis were calculated to evaluate the performance of these non-invasive methods in NAFLD patients, adopting liver biopsy as the gold standard. RESULTS: A total of 104 patients were studied. At three different cutoff values (7.9, 8.7 and 9.6kPa) THE presented the highest sensitivity values (95%, 90% and 85% respectively), and the highest NPV (98%, 96.4% and 95.1% respectively) for the diagnosis of advanced fibrosis. It also presented the highest AUROC (0.87; CI 95% 0.78-0.97). CONCLUSION: When compared to the gold standard, transient hepatic elastography presented the best performance for the diagnosis and exclusion of advanced fibrosis in patients with NAFLD, overcoming APRI, FIB4 and NAFLD score.

A cross-sectional study was conducted to evaluate and compare dietary intake, type of assistance (Basic Health Units - UBS and Family Health Strategies - ESF) and participation in the "Bolsa Família" Program (PBF) among users of the Brazilian Unified Health System, (SUS). The sample was composed of individuals of both sexes between 18 and 78 years of age in Porto Alegre, state of Rio Grande do Sul. Socioeconomic, clinical and food consumption data were collected via a questionnaire adapted from the SISVAN and VIGITEL national surveys. The analyses were conducted using R3.1 software. Of the 187 patients, 91 were affiliated to the ESF, 96 to UBS and 40 were registered with the PBF. A healthy eating pattern was identified in only 41% of SUS users. It was observed that 55% did not consume raw salad (37% p = 0.04) and vegetable consumption was lower among the PBF users (67.5% versus 75.9%; p = 0.02). There was no significant difference in food consumption considering the kind of assistance (ESF or UBS). A healthy consumption pattern was not associated with demographic and socioeconomic variables. The majority of beneficiaries of the PBF did not admit to healthy eating patterns. Therefore, effective health promotion and prevention is needed for this population, mainly among the beneficiaries of the PBF.
Foi realizado estudo transversal com objetivo de avaliar e comparar o consumo alimentar de usuários do Sistema Único de Saúde (SUS), segundo tipo de assistência (Unidades Básicas de Saúde-UBS e Estratégias de Saúde da Família-ESF) e participação no Programa Bolsa Família (PBF). A amostra foi composta por indivíduos de 18 a 78 anos, de ambos sexos, de Porto Alegre-RS. Foram coletados dados socioeconômicos, clínicos e de consumo alimentar através de questionário adaptado dos inquéritos nacionais SISVAN e VIGITEL. As análises foram realizadas no software R3.1. Dos 187 entrevistados, 91 pertenciam à ESF, 96 à UBS e 40 eram beneficiários do PBF. O padrão alimentar saudável foi identificado em apenas 41% dos usuários do SUS. Entre os beneficiários do PBF, consumo de hortaliças foi menor (67,5% vs 75,9;p = 0,02) e 55% não consumiam salada crua (37%;p = 0,04). Não houve diferença significativa no consumo considerando o tipo de assistência recebida (ESF ou UBS). O padrão de consumo saudável não foi associado às variáveis demográficas e socioeconômicas. A maioria dos beneficiados pelo PBF também não demonstrou padrão alimentar saudável. Portanto, maiores esforços para efetiva promoção e prevenção da saúde são necessários para essa população, principalmente entre os beneficiados pelo PBF.

BACKGROUND: Although widely applied, there is no consensus about the characteristics of the diets prescribed in the immediate preoperative period of bariatric surgery (BS). The objective of this study was to perform a survey on preoperative dietary management in BS centers. METHODS: This was a cross-sectional study with BS Brazilian centers. Only BS centers with certificate of excellence by Surgical Review Corporation were included. An electronic questionnaire was applied to assess details about the dietary management in the immediate preoperative period of BS. RESULTS: Of the 15 centers invited, 80% (n = 12) answered the questionnaire. Preoperative weight loss was required to patients in all 12 centers. For 8.3% (n = 1), this request was applied to all patients; 91.7% (n = 11) of the centers requested weight loss in specific cases. Ten (83.3%) centers prescribed restrictive diets; none of these adopted a standard dietary protocol. The caloric value of the diets ranged from 800 to 2000 kcal/day. The duration of the diet ranged from 10 to 20 days in 40% (n = 4) of the centers and from 20 to 90 days in 60% (n = 6) of the centers. Dietary prescription was based on team consensus in 100% (n = 12) of the centers. In 33.3% (n = 4) of the centers, scientific evidence supporting dietary prescription was cited. CONCLUSION: This study identified the frequent practice of requesting preoperative weight loss and the diversity of diets used in the immediate preoperative period by Brazilian BS centers. Future guideline proposal is needed on preoperative BS diets.

AIM: To perform a systematic review to evaluate the incidence and prevalence of non-alcoholic fatty liver disease (NAFLD) in adult patients with sarcopenia. METHODS: Randomized clinical trials, cross-sectional or cohort studies including adult patients (over 18 years) with sarcopenia were selected. The primary outcomes of interest were the prevalence or incidence of NAFLD in sarcopenic patients. In the screening process, 44 full-text articles were included in the review and 41 studies were excluded. RESULTS: Three cross-sectional studies were included. The authors attempted to perform a systematic review, but due to the differences between the studies, a qualitative synthesis was provided. The diagnosis of NAFLD was made by non-invasive methods (image methods or any surrogate markers) in all three evaluated studies. All the studies suggested that there was an independent association between sarcopenia and NAFLD. CONCLUSION: Sarcopenia is independently associated with NAFLD and possibly to an advanced fibrosis.
RESUMO
INTRODUCTION:: Validation of food frequency questionnaires (FFQs) is recommended for accurate measurement of habitual food consumption. We assessed the relative validity of a FFQ in patients coinfected with hepatitis C virus and human immunodeficiency virus. METHODS:: Each patient responded to a FFQ and three 24-hour food recalls. Pearson's correlation and weighted Kappa index analyses were performed to identify the FFQ relative validity and concordance. RESULTS:: De-attenuated correlation coefficients ranged from 0.35 (vitamin B1) to 0.81 (selenium). The concordance index ranged from 0.07 (vitamin C) to 0.51 (calcium). CONCLUSIONS:: The FFQ showed satisfactory relative validity for most nutrients.

ABSTRACT BACKGROUND Vitamin D is known for its immunomodulatory, anti-inflammatory and antifibrotic properties, which are quite relevant in the pathogenesis and treatment of many causes of chronic liver disease. OBJECTIVE This study aimed to evaluate the association between serum vitamin D levels and the histopathological findings in patients with chronic hepatitis C virus infection. METHODS Cross-sectional study composed of patients with chronic hepatitis C. All patients underwent vitamin D 25 dosage and anthropometric data analysis. Liver biopsy was performed in a maximum 36-month period before inclusion in the study. RESULTS Of the 74 patients included in the study, 45 (60.8%) were women, mean age was 57.03±9.24 years, and 63 (85.1%) were white. No association was observed between the serum levels of vitamin D and inflammatory activity (P=0.699) nor with the degree of liver fibrosis (P=0.269). CONCLUSION In this study, no association was observed between vitamin D and inflammatory activity, as well as the degree of liver fibrosis, in patients with chronic hepatitis C.
RESUMO CONTEXTO A vitamina D é conhecida por possuir propriedades imunomoduladoras, anti-inflamatórias e antifibróticas, relevantes na patogênese e tratamento de muitas causas de doença hepática crônica. OBJETIVO Este estudo tem como objetivo avaliar a associação entre os níveis séricos de vitamina D e os achados histopatológicos em pacientes com infecção crônica do vírus da hepatite C. MÉTODOS Estudo transversal, composto por pacientes com hepatite C crônica. Todos os pacientes foram submetidos à dosagem de vitamina D 25 e análise de dados antropométricos. A biópsia hepática foi realizada em um período máximo de 36 meses antes da inclusão no estudo. RESULTADOS Dos 74 pacientes incluídos no estudo, 45 (60,8%) eram mulheres, média de idade de 57,03±9,24 anos e 63 (85,1%) eram brancos. Não foi observada associação entre os níveis séricos de vitamina D e atividade inflamatória (P=0,699), nem com o grau de fibrose hepática (P=0,269). CONCLUSÃO No presente estudo, não foi observada associação entre a vitamina D e a atividade inflamatória, bem como com o grau de fibrose hepática, em pacientes com hepatite C crônica.

BACKGROUND: Caffeine consumption has been associated to decreased levels of liver enzymes and lower risk of fibrosis in patients with hepatitis C virus. Objectives This study aimed to evaluate the association between caffeine consumption and inflammatory activity or degree of liver fibrosis in patients with hepatitis C virus infection. METHODS: A cross-sectional study of patients with chronic hepatitis C virus infection treated in an outpatient Gastroenterology Unit of Santa Casa Hospital (Porto Alegre - Brasil). Patients were interviewed regarding the consumption of caffeine and anthropometric assessment was performed. Liver biopsy was performed in a maximum period of 36 months before inclusion in the study. RESULTS: There were 113 patients, 67 (59.3%) females, 48 (42.5%) were aged between 52 and 62 years, and 101 (89.4%) were white. The average caffeine consumption was 251.41 ± 232.32 mg/day, and 70 (62%) patients consumed up to 250 mg/day of caffeine. There was no association between caffeine consumption and inflammatory activity on liver biopsy. On the other hand, when evaluating the caffeine consumption liver fibrosis an inverse association was observed. CONCLUSIONS: The greater consumption of caffeine was associated with lower liver fibrosis. There was no association between caffeine consumption and inflammatory activity.

Contexto O consumo de cafeína tem sido relacionado à diminuição dos níveis de enzimas hepáticas e menor risco de fibrose em pacientes portadores do vírus da hepatite C. Objetivo O presente estudo tem por objetivo avaliar a associação do consumo da cafeína com a atividade inflamatória e o grau de fibrose hepática em pacientes com infecção pelo vírus da hepatite C. Métodos Estudo transversal, constituído por pacientes com infecção pelo vírus da hepatite C atendidos no ambulatório de Gastroenterologia do Complexo Hospitalar Santa Casa (Porto Alegre - Brasil). Os pacientes foram entrevistados e avaliados individualmente quanto ao consumo de cafeína e antropometria. A biópsia hepática foi realizada em um período de no máximo 36 meses antes da inclusão no estudo. Resultados Foram avaliados 113 pacientes, sendo 67 (59,3%) do sexo feminino, 48 (42,5%) apresentavam idade entre 52 e 62 anos, e 101 (89,4%) eram de cor branca. O consumo médio de cafeína foi de 251,41 ± 232,32 mg/dia, sendo que 70 (62%) pacientes consumiam até 250 mg/dia de cafeína. Não houve associação entre o consumo de cafeína e a atividade inflamatória na biópsia hepática. Por outro lado, quando avaliada a associação entre o consumo de cafeína e fibrose hepática observou-se relação inversa. Conclusões O maior consumo de cafeína apresentou associação com menor grau de fibrose hepática. Não houve associação entre o consumo de cafeína e a atividade inflamatória. .

Non-alcoholic fatty liver disease (NAFLD) is defined as a spectrum of liver diseases ranging from simple steatosis to steatohepatitis (NASH). Alterations in intestinal microbiota and inflammatory response may play a key role in disease progression and development of complications in liver diseases, mainly in cirrhosis and NASH. The aim of this study was to perform a systematic review on randomized clinical trials (RCTs) testing probiotics, prebiotics or both (synbiotics) in the treatment of NAFLD in adult patients. After the screening process, 9 full-text articles were included in the review and 6 studies were excluded. Three randomized controlled trials were finally included in the qualitative synthesis. All patients in all the 3 studies were randomized to receive different formulations of probiotics, synbiotics or placebo. Reductions in aminotransferases were observed in the treated group in 2 of the studies. However, in one study reductions were also detected in the control group. In conclusion, the available evidence precludes, for the moment, recommendations on the use of pre and probiotics in clinical practice.

The assessment of the relationship between food intake and sociodemographic factors is crucial for developing effective public health policies. The present study aimed to examine dietary patterns in pregnant women and the association between these patterns and sociodemographic characteristics. Pregnant women attending general practices in southern Brazil (n = 712) answered a questionnaire and a food-frequency questionnaire with 88 items. Three dietary patterns were identified using cluster analysis. The association between the dietary patterns and sociodemographic variables was analyzed using the chi-square test and adjusted standardized residuals (p < 0,05). The restricted pattern was associated with lower maternal age, not living with a partner and being a non-working student. The varied pattern was associated with older maternal age, living with a partner, being employed and higher levels of education and income. The common-Brazilian dietary pattern included traditional Brazilian food items and was associated with lower levels of education and income, being unemployed and being a non-student.

OBJECTIVE: To evaluate dietary quality in a sample of pregnant women based on one simple and objective parameter. METHODS: Pregnant women (n = 712), between 16 and 36 weeks, attending primary care clinics in Porto Alegre and Bento Gonçalves, Southern Brazil, in 2010 were recruited to take part. The Healthy Eating Index for Brazilian Pregnancy (HEIP-B) was created, derived from the American instrument called Alternate Healthy Eating Index for Pregnancy (AHEI-P). Questionnaires on frequency of consumption and on socio-demographic factors were completed. Focused principal component analysis (ACPF) was used to assess the relationship between the index and nutrients relevant to pregnancy. RESULTS: The median (interquartile range) of AHEI-P and HEIP-B were 66.6 (57.8-72.4) and 67.4 (60.0-73.4), respectively. The HEIP-B showed a good positive correlation with nutrients which are specifically recommended for pregnancy: folate (r = 0.8; p < 0.001), calcium (r = 0.6; p < 0.001) and iron (r = 0.7; p < 0.001). CONCLUSIONS: The quality of the diet of the pregnant women in this study was classified as within the "improvements needed" cut off point, which demonstrates the need for more specific education on nutrition for this stage of life. The index showed good correlations and, thus, may be considered an effective tool for assessing the quality of nutrition during pregnancy.
