Nonalcoholic fatty liver disease in adolescents with phenylketonuria

Abstract Objective: This study aimed to investigate non-alcoholic fatty liver disease (NAFLD) occurrence and factors associated with the disease in phenylketonuria (PKU) patients undergoing exclusive dietary treatment. Method: This cross-sectional study included 101 adolescents 10 to < 20 years of age with PKU, who were undergoing exclusive dietary treatment and monitored since early diagnosis at a single reference service. Anthropometric and biochemical assessments were performed and food intake was documented, and an ultrasound diagnosis of NAFLD was established. Data were evaluated using the Student's t-test for continuous variables, the chi-square for categorical variables, and logistic regression using the Wald chi-squared test; differences with p < 0.05 were considered to be statistically significant. Results: NAFLD was detected in 26 (25.7%) teenagers. There was no difference in prevalence between the sexes or nutritional status. The final logistic regression model revealed low sensitivity (26.1%) and high specificity (94.7%). The specificity suggested a lower likelihood of NAFLD in older adolescents, in the presence of normal or high levels of alkaline phosphatase, lower carbohydrate intake, and adequate protein and lipid intake. Conclusions: The prevalence of NAFLD in adolescents with PKU was higher than that found in healthy Brazilian adolescents and similar to that found in obese Brazilian children, suggesting a higher risk for NAFLD in patients with PKU treated exclusively by dietary modification.

Influence of blood phenylalanine level variations on the development of executive functions and social cognition in children with phenylketonuria

Abstract Objective: To investigate the performance of 27 children with phenylketonuria (PKU) in tests of Executive Functions (EF) and Social Cognition (SC), and their associations with metabolic control inferred by phenylalanine (Phe) levels. Methods: The PKU group was dichotomized according to baseline Phe-levels into; "classical PKU"(n = 14), with Phe-levels above 1200 µmol/L (> 20 mg/dL); and "mild PKU" (n = 13) with Phe-between 360 and 1200 µmol/L (6-20 mg/dL). The neuropsychological assessment focused on the EF and SC subtests of the NEPSY-II battery and intellectual performance. Children were compared to age-matched healthy participants. Results: Participants with PKU presented significantly lower Intellectual Quotient (IQ) compared to controls (p = 0.001). Regarding EF analysis adjusted by age and IQ, significant differences between groups were observed only in the executive attention subtests (p = 0.029). The SC set of variables was significantly different between groups (p = 0.003), as in the affective recognition task (p < 0.001). In the PKU group, the relative variation of Phe-achieved 32.1 ± 21.0%. Relative Phe-variation was correlated only with measures of Working Memory (p < 0.001), Verbal Fluency (p = 0.004), Inhibitory Control (p = 0.035) and Theory of Mind (p = 0.003). Conclusions: Phonological Verbal Fluency, Working Memory, Inhibitory Control, and Theory of Mind were shown to be most vulnerable when there is non-ideal metabolic control. Variations in the level of Phe-may have a selective negative effect on Executive Functions and Social Cognition, but not on intellectual performance.

Overweight/obesity in adolescents with phenylketonuria: protective and predisposing factors

Abstract Objective: To estimate the prevalence and factors associated with overweight/obesity development in adolescents with early diagnosed phenylketonuria treated exclusively by diet. Methodology: In this cross-sectional study anthropometric measurements, serum phenylalanine levels, and 10 metabolites associated with lipid and carbohydrate metabolism were analyzed in 101 adolescents aged 10-20 years. Adolescents were categorized into overweight/obesity and eutrophic/low body mass index groups. These patients were compared using Student's t-test, Pearson's chi-square test, Wald's chi-square test for multivariate analysis. Further, to verify whether the prevalence of overweight/obesity found in the study population was similar to that in the general population, the authors compared the nutritional status of 46 patients aged 13-17 years with that of healthy students of the same age from the National School Health Survey using the chi-square test for adherence. The significance threshold was p < 0.5. Results: The prevalence of overweight/obesity in adolescents was 27.7%. There was no difference in prevalence between sexes. Older age was a protective factor and Increased Homeostasis Model Assessment Insulin Resistance index and high phenylalanine and low-density lipoprotein cholesterol levels were predictive factors for overweight/obesity. The equality hypothesis was not rejected in the comparison of nutritional states of 46 patients aged 13-17 years and healthy students of the same age. Conclusion: The prevalence of overweight/obesity in phenylketonuria adolescents was similar to what is found in healthy adolescents.

Progress on low protein diet for patients with chronic kidney disease / 中华全科医师杂志

Nutrition therapy is considered as the basis for prevention and management of chronic kidney disease (CKD), throughout the three-tier prevention strategies of CKD. The primary objective is to delay the disease progression, correct metabolic disorders, and improve the outcomes of CKD. Low protein diet has been recognized as an important therapeutic measure in CKD, but the quantity, quality and source of protein are always the points of contention. Recently, both domestic and foreign guidelines have been updated on the amount of protein intake. In addition to quantity, attention has been paid to the type and diversity of proteins. With the rise of plant-based food consumption and the concept of vegetarian diet, the scientific community began to review the benefits of plant protein again, and a plant-based diet is recommend extensively. Whether the plant-based dietary pattern is also suitable for CKD patients who need a low-protein diet, and whether it could meet the nutritional needs of CKD patients are hot topics, this article reviews the recent progress of these research hotspots.

Nutrición en las enfermedades inflamatorias del intestino. Una revisión / Nutrition in inflammatory bowel disease. A review / Nutrição em doenças inflamatórias intestinais. Uma revisão

Resumen: Existe evidencia epidemiológica en humanos, a partir de estudios de cohortes de grandes poblaciones, de que la dieta ejerce una fuerte influencia en el desarrollo y curso de la enfermedad inflamatoria intestinal (EII). Además, la mayoría de los tratamientos médicos basados en la evidencia para las EII están dirigidos a suprimir la respuesta inmunitaria y conllevan riesgos de efectos secundarios importantes. La evidencia actual ha demostrado varios factores dietéticos que probablemente protejan contra los brotes, como la fibra, el zinc y la vitamina D en ambas formas de EII y una alta proporción de Ácidos grasos poliinsaturados (AGPI) n -3 / n -6 en la dieta en la CU. Otros factores aumentan el riesgo de brotes, son los alimentos que contienen ácido mirístico, las carnes rojas y el azúcar. Esta revisión explorará las interacciones de la dieta y el sistema inmunológico en el contexto de la enfermedad de Crohn (EC) y la colitis ulcerosa (CU), centrándose en el papel de la dieta en la patogénesis, en particular la interacción con el sistema inmunológico del paciente. Al mismo tiempo se analizará el rol de la nutrición médica como intervención terapéutica.

Abstract: There is vast epidemiological evidence based on cohort studies of large populations of humans, that diet exerts a strong influence on the development and outcome of inflammatory bowel disease. Besides, most evidence-based medical therapies for this condition aim to suppress the immune response and entail significant side effects. Current evidence has proved that several diet factors probably protect against outbreaks, as in the case of fibre, zinc and vitamin D in both forms of inflammatory bowel disease and a high proportion of polyunsaturated fatty acids (PUFAs) n -3 / n -6 in the ICU diet. Other foods also impact the outbreak risk, such as those containing myristic acid, red meats and sugar. This review will explore diet interactions and the immune system within the context of Crohn's disease and ulcerative colitis, focusing on the role of diet in the pathogenesis, in particular in terms of its interaction with the patient's immune system. Simultaneously, the role of medical nutrition will be analysed as a therapeutic intervention.

Resumo: Há evidências epidemiológicas em seres humanos de estudos de coorte de grandes populações que a dieta tem uma forte influência no desenvolvimento e no curso da Doença Inflamatória Intestinal (DII). Além disso, a maioria dos tratamentos médicos baseados em evidências para DII têm como objetivo suprimir a resposta imunológica e acarretam riscos de efeitos colaterais significativos. A evidência atual mostrou vários fatores dietéticos que provavelmente protegem contra surtos, como fibra, zinco e vitamina D em ambas as formas de DII e uma alta proporção de ácidos graxos poliinsaturados (PUFAs) n -3 / n -6 na dieta na colite ulcerativa (UC). Outros fatores que aumentam o risco de surtos são os alimentos que contêm ácido mirístico, a carne vermelha e o açúcar. Esta revisão explora as interações da dieta e do sistema imunológico no contexto da Doença de Crohn (DC) e da Colite Ulcerativa (UC), com foco no papel da dieta na patogênese, em particular na interação com o sistema imunológico do paciente. Ao mesmo tempo, faz-se uma análise do papel da nutrição médica como intervenção terapêutica.

Nueva ecuación para la estimación de la natriuresis diaria a partir de parámetros en plasma y orina aislada en población chilena / A new equation to estimate daily natriuresis from parameters in plasma and spot urine sample in the Chilean population

Background: Excessive sodium intake is associated with increased cardiovascular morbidity and mortality. Daily sodium intake is usually inferred from sodium excretion in a 24-hour urine collection, which is cumbersome and prone to errors. Different formulas have attempted to estimate 24-hour urinary sodium from a spot urine sample. Unfortunately, their concordances are insufficient and have not been tested in our population. Aim: To develop an equation to predict 24-hour urine sodium from parameters in plasma and spot urine samples. To validate the equation and compare it with other formulas in Chilean population. Material and Methods: Analysis of 24-hour urine collections, plasma sample and spot urine sample from 174 adult outpatients (81% females) with an estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73m2. These were collected between 2015 and 2019 using standardized methods and educating patients about the correct method to collect 24 h urine samples. In all these patients, creatinine and electrolytes were measured in plasma and urine. A new equation was developed using a multiple linear regression model. Results: Twenty-four-hour urine sodium excretion was significantly correlated with age, weight, height, eGFR, plasma osmolarity, urine electrolytes and parameters obtained from spot urine sample, among others. The new equation had a linear correlation with 24-hour natriuresis of 0.91 and the concordance was 0.9. The predictive capacity of the new equation was better than the existing formulas. Conclusions: We developed a formula to accurately predict daily natriuresis in the Chilean population.

Hospital admission flow and nutritional support in a cohort of pediatric patients with COVID-19 / Fluxo de admissão hospitalar e suporte nutricional em uma coorte de pacientes pediátricos com COVID-19

Abstract In view of the current panorama of hospital nutritional care, it is necessary to review nutritional care practices in hospital units, in order to ensure nutritional monitoring and quality of care. Therefore, it is necessary to build flows of nutritional assistance practices at the pediatric hospital level, based on the recommendations of the Federal Council of Nutritionists and the Brazilian Society of Parenteral and Enteral Nutrition, aiming at not generating a deficit in the nutritional monitoring of the patient and in reducing the risk of contamination of the professional. When individual protection equipment is available, nutritional admission will be made in person and during hospitalization, monitoring can be performed using secondary data from electronic medical records and / or telecommunication with the multidisciplinary team. The implementation of nutritional routines in hospitals in times of Covid-19 pandemic generates more assertive conducts for the prevention and treatment of malnutrition and other nutritional implications, also guaranteeing the safety of professionals in assistance in pediatric units..

Resumo Diante do panorama atual da assistência nutricional hospitalar, torna-se necessário a revisão das práticas de assistência nutricional em unidades hospitalares, visando garantir monitoramento nutricional e qualidade assistencial. Portanto, faz-se necessário a construção de fluxos de práticas da assistência nutricional em nível hospitalar pediátrico, baseados nas recomendações do Conselho Federal de Nutricionistas e da Sociedade Brasileira de Nutrição Parenteral e Enteral, visando não gerar déficit no monitoramento nutricional ao paciente e em reduzir o risco de contaminação do profissional. Quando há a disponibilidade de equipamento de proteção individual a admissão nutricional será feita presencialmente e durante o internamento poderá ser realizado monitoramento por meio de dados secundários provenientes do prontuário eletrônico e/ou telecomunicação com a equipe multidisciplinar. A implantação de rotinas nutricionais em âmbito hospitalar em tempos de pandemia da COVID-19 gera condutas mais assertivas para a prevenção e tratamento da desnutrição e de outras implicações nutricionais, garantindo também a segurança do profissional na assistência em unidades pediátricas.

O uso terapêutico dos alimentos em meados do século XIX / The therapeutic use of food in the mid-19th century

Introdução: No decorrer do século XIX surgiram as primeiras informações a respeito das substâncias químicas contidas nos alimentos. A partir dessas descobertas, a higiene alimentar como meio terapêutico estabeleceu critérios para a prescrição de azote (nitrogênio) e carbone (carbono), bem como recomendações alimentares nos diferentes ciclos de vida e estados de convalescença. Objetivos: Este trabalhou buscou analisar como e para que fins eram prescritos alguns alimentos cuja composição química era caracterizada pela presença do azote (nitrogênio) e carbone (carbono). Método: Foram utilizados como fonte de pesquisa os cadernos de visitas (prontuários) de embarcações encontrados no Arquivo Histórico da Marinha Portuguesa, os tratados médicos do período e publicações referentes à história da ciência e nutrição. Resultados e discussão: Nos cadernos de visitas consultados (anos 1859 e1863), as refeições à base de alimentos de origem animal (ricos em azote), como os caldos de carne e de galinha, foram as mais prescritas aos doentes, pois se pautavam nos princípios da dieta fibrinosa, que promovia a reparação tecidual e crescimento da matéria orgânica. Considerações finais: Ao longo dos dois últimos séculos, muitas teorias a respeito da função dos alimentos se modificaram, mas parte significativa de seus pressupostos foram constituídos no decorrer do século XIX.

Introduction: During the 19th century, emerged the first information about the chemical substances contained in food. From these discoveries, food hygiene as a therapeutic mean established criteria for the prescription of nitrogen (nitrogen) and carbon (carbon), as well as dietary recommendations in the different life cycles and convalescent states. Objectives: This work sought to analyze how and for what purposes some foods whose chemical composition was characterized by the presence of nitrogen (nitrogen) and carbon (carbon)were prescribed . Methodology: The visiting notebooks (medical records) of vessels found in the Historical Archive of the Portuguese Navy, medical treaties of the period and publications referring to the history of science and nutrition were used as a research source. Results and discussion: In the consulted notebooks (years 1859 and 1863), meals based on animal foods (rich in nitrogen), such as meat and chicken broths, were the most prescribed to patients, as they were based on principles of the fibrinous diet, which promoted tissue repair and growth of organic matter. Final considerations: Over the past two centuries, many theories about the function of food have changed, but a significant part of their assumptions were made during the 19th century.

Efeitos da restrição de carboidratos no manejo do diabetes mellitus: revisão de literatura científica / Effects of carbohydrate-restricted diets in the management of diabetes mellitus: review of scientific literature

O objetivo do presente estudo foi avaliar, por meio de uma revisão da literatura, evidências da utilização de dietas com restrição de carboidratos no manejo do diabetes mellitus (DM). As buscas eletrônicas e manuais foram até abril de 2019, e incluíram trabalhos publicados a partir de 2008. Foram excluídos estudos de pesquisas in vitro e em animais, revisões de literatura, livros, monografias, dissertações, teses, estudos de caso e relatos de caso. Os artigos remanescentes foram submetidos à análise de sua qualidade metodológica pela Escala JADAD cinco pontos. Um total de 19 estudos randomizados e com qualidade média de três pontos foram selecionados e analisados quanto aos tipos de dieta utilizadas, adesão, tipo de DM, tempo de intervenção, consumo reportado de carboidratos e resultados observados para os grupos controle e intervenção. Dentre os parâmetros escolhidos para mensurar os possíveis efeitos das dietas, destacaram-se alteração de peso e IMC, Hb1Ac, variabilidade ou controle glicêmico, perfil lipídico e alteração nas doses de insulina ou medicação utilizadas. Em quatro estudos não foram observadas vantagens significativas de uma dieta restrita em carboidratos, e 15 trabalhos relataram melhoras em um ou mais parâmetros. Tais resultados podem representar uma grande vantagem na adoção desta estratégia alimentar no manejo do DM e na prevenção de complicações da doença. Contudo, existem limitações nos estudos, que precisam ter suas hipóteses verificadas no longo prazo, e pesquisas adicionais devem ser realizadas para configurar uma estratégia oficial no controle do DM. (AU)

This study aimed to evaluate, through a literature review, evidence of the use of diets with carbohydrate restriction in the management of diabetes mellitus (DM). Electronic and manual searches were conducted until April 2019, including works published from 2008 onwards. Studies on in vitro and animal research, literature reviews, books, monographs, dissertations, theses, case studies and case reports were excluded. The remaining articles were submitted to analysis of their methodological quality by the five-point JADAD Scale. Nineteen randomized studies with an average quality of three points were selected and analyzed regarding the types of diet used, adherence, type of DM, time of intervention, reported consumption of carbohydrates and results observed for the control and intervention group. Among the parameters chosen to measure the possible effects of diets, weight and BMI changes, Hb1Ac, variability or glycemic control, lipid profile and changes in insulin doses or medication used stood out. In four studies, no significant advantages were observed from a carbohydraterestricted diet, and 15 studies reported improvements in one or more parameters. Such results can represent a great advantage in adopting this dietary strategy in the management of DM and in preventing complications of the disease. However, there are limitations in the studies, which need to have their hypotheses verified in the long term, and additional research must be carried out to configure an official strategy in the control of DM.

Barreras estructurales en la atención nutricia a personas con enfermedad renal crónica en México / Structural barriers in care nutrition for people with chronic kidney disease in Mexico

Resumen Este trabajo se propone describir las barreras estructurales que el personal de salud identifica para brindar atención nutricia a personas con enfermedad renal crónica (ERC). Se llevó a cabo un estudio cualitativo en la ciudad de San Luis Potosí, México. Se entrevistó a 21 profesionales de salud (nutriólogos, enfermeras y nefrólogos) que trabajan en unidades de hemodiálisis. Se realizó un análisis crítico del discurso. Los participantes del estudio señalan diversas barreras estructurales que obstaculizan la inclusión de la terapia nutricional en el tratamiento de la ERC: la falta de cobertura universal de salud en México, lo que genera que no todas las personas con ERC accedan a un tratamiento nutricio; la infraestructura inadecuada en las unidades de hemodiálisis, donde los nutriólogos carecen de un espacio físico para dar consulta o asesoría; la ausencia de normativa y protocolos para la atención nutricia y; la falta de recursos humanos en nutrición especializados en ERC. Como conclusión, se destaca que la atención nutricia para los enfermos renales en México es incipiente y poco sistematizada. Se requiere instituir una atención universal, así como modificar la normativa nacional para incluir al personal de nutrición especializado en el tratamiento interdisciplinar en beneficio de quienes padecen dicha enfermedad.

Abstract This study describes the structural barriers that the health personnel identifies to provide nutritional care to people with chronic kidney disease. A qualitative study was carried out in San Luis Potosí, Mexico. We interviewed 21 health professionals (nutritionists, nurses and nephrologists) who work in hemodialysis units. Critical discourse analysis was performed. The study participants point out various structural barriers that hinder the inclusion of diet therapy in the treatment of CKD: the lack of universal health coverage in Mexico, which means that not all people with CKD have access to nutritional treatment; inadequate infrastructure in hemodialysis units, where nutritionists lack a physical space to provide appointment or advice; absence of regulations and protocols for nutritional care; lack of human resources in nutrition, specialized in CKD. In conclusion, it is highlighted that nutritional care for kidney patients in Mexico is incipient and little systematized. It is necessary to institute universal care, as well as modify the national regulations to include specialized nutrition personnel to interdisciplinary treatment for the benefit of those who suffer from the disease.

Ulcerative colitis in the postpartum period

We describe a scarcely reported case in which ulcerative colitis (UC) occurred in the postpartum period. The aims of this case report are to reinforce the recent assertion that a diet is a ubiquitous environmental factor in inflammatory bowel disease (IBD) and that a plant-based diet (PBD) is recommended for IBD. A 29-year-old woman normally delivered her first child. She first noticed bloody diarrhea 4.5 months after delivery. She was diagnosed with UC (left-sided colitis, moderate severity). Sulfasalazine induced remission. She then experienced and learned about PBD during an educational hospitalization. She resumed breast-feeding and stopped medication. An interview and questionnaire revealed a change in her diet 3 months after delivery, from a sound diet (plant-based diet score: 25) to an unhealthy diet (score: 9). It happened along with a change in residence, from her parent's home where her mother prepared traditional Japanese meals to her home where she prepared meals by herself. A feeling of release from childbirth prompted her to eat sweets and cheese despite being aware that the quality of the meals deteriorated. We described a scarcely reported case in which UC occurred in the postpartum period. It happened along with a change in her diet, from a sound diet to an unhealthy diet due to a feeling of release from childbirth. She replaced an omnivorous diet by PBD and stopped medication. The critical role of diet is largely ignored by healthcare professionals. We believe that greater appreciation of diet will change and improve management of IBD.

Evidence related to sodium restriction in patients with heart failure / Pruebas relacionadas con la restricción de sodio en pacientes con insuficiencia cardíaca / Evidências relacionadas à restrição de sódio em pacientes com insuficiência cardíaca

ABSTRACT Objectives: to analyze the scientific production about sodium restriction in patients with heart failure. Methods: integrative literature review from articles published from 2007 to 2017, located in the CINAHL and Scopus databases. Results: thirteen studies were analyzed. Sodium intake restriction was associated with lower unfavorable clinical outcomes in patients with marked symptomatology. The 24-hour urine sodium dosage was the main tool to assess adherence to the low sodium diet. Conclusions: based on the studies included in this review, in symptomatic patients, dietary sodium restriction should be encouraged in clinical practice as a protective measure for health. However, in asymptomatic patients, it should be well studied.

RESUMEN Objetivo: analizar la producción científica sobre la restricción de sodio en pacientes con insuficiencia cardíaca. Métodos: revisión integral de la literatura de artículos publicados de 2007 a 2017, ubicados en las bases de datos CINAHL y Scopus. Resultados: se analizaron trece estudios. La restricción en la ingesta de sodio se asoció con resultados clínicos desfavorables más bajos en pacientes con marcada sintomatología. La dosis de sodio en orina de 24 horas fue la herramienta principal para evaluar el cumplimiento de la dieta baja en sodio. Conclusión: según los estudios incluidos en esta revisión, en pacientes sintomáticos, se debe fomentar la restricción de sodio en la dieta en la práctica clínica como medida de protección para la salud. Sin embargo, en pacientes asintomáticos, debe estudiarse bien.

RESUMO Objetivos: analisar a produção científica acerca da restrição de sódio em pacientes com insuficiência cardíaca. Métodos: revisão integrativa da literatura, a partir de artigos publicados no período de 2007 a 2017, localizados nas bases de dados CINAHL e Scopus. Resultados: foram analisados 13 estudos. A restrição no consumo de sódio se mostrou associada a menores desfechos clínicos desfavoráveis em pacientes com sintomatologia acentuada. A dosagem de sódio na urina coletada em 24 horas foi a ferramenta principal para avaliar adesão à dieta com baixo teor de sódio. Conclusões: com base nos estudos incluídos nesta revisão, em pacientes sintomáticos, a restrição de sódio na dieta deve ser encorajada na prática clínica como medida protetora à saúde. No entanto, em pacientes assintomáticos, deve ser bem estudada.

Condutas para o manejo da anorexia em cuidados paliativos: revisão integrativa / Management approach for anorexia in palliative care: an integrative literature review / Conducta para el manejo de anorexia en cuidado paliativo: revisión integradora

Objetivo: Identificar as evidências científicas acerca das condutas para o manejo da anorexia em cuidados paliativos. Métodos: Trata-se de uma revisão integrativa, cujo levantamento bibliográfico dos dados deu-se através da pesquisa em quatro bases de dados/bibliotecas virtuais. Incluíram-se artigos em português, inglês e espanhol, publicados nos últimos dez anos e com o texto completo disponível. Resultados: Foram elegíveis 25 artigos, e foram atribuídos dois eixos temáticos para melhor ilustrar os dados encontrados: o manejo farmacológico e o não-farmacológico. Corticosteroides, progestinas, anamorelina e dronabinol foram os fármacos mais pesquisados para o controle da anorexia, com maiores evidências de eficácia nos 3 primeiros. No contexto não-farmacológico, o aconselhamento nutricional foi a medida mais indicada, incluindo a fortificação de alimentos e uso de suplementos e a nutrição artificial mais controversa. Conclusão: Os achados desta revisão podem colaborar para a elaboração de protocolos para o manejo da anorexia em cuidados paliativos

Objective: The study's main goal has been to identify scientific evidence on the management of anorexia in palliative care. Methods: This is an integrative review, whose data collection occurred by researching four databases/virtual libraries. Articles in Portuguese, English, and Spanish, published over the last ten years and with the full text available, were included. Results: 25 articles were selected, and two thematic axes were assigned to better illustrate the data found: pharmacological and non-pharmacological management. Corticosteroids, progestins, anamorelin, and dronabinol were the most-researched drugs for the control of anorexia, with greater evidence of effectiveness for the first three. In the non-pharmacological treatment, nutritional counseling was the most recommended measure, including the fortification of foods and the use of supplements and the more-controversial artificial nutrition. Conclusion: The findings of this review may aid in the development of protocols for the treatment of anorexia in palliative care

Autism spectrum disorder: a systematic review about nutritional interventions / Transtorno do espectro autista: uma revisão sistemática sobre intervenções nutricionais

ABSTRACT Objective: To identify and analyze the scientific evidence of nutritional interventions performed in children and adolescents with Autism Spectrum Disorder. Data sources: A systematic review was conducted in the MEDLINE, Cochrane Library, Embase, LILACS, Google Scholar, PubMed, PsycINFO and Periódicos CAPES databases, using a search strategy to identify studies published between January 2003 and March 2018, in Portuguese, English and Spanish. Were included studies that described nutritional interventions in children and adolescents with autism spectrum disorders and assessed autistic behavior and/or gastrointestinal symptoms. We excluded other review articles and studies that did not include a control group in the research design. The studies were reviewed for descriptive information, and the quality of evidence was assessed through the GRADE system. Data synthesis: 18 studies were included in the review, being 16 randomized clinical trials, 1 case-control study and 1 open-label trial. As a result, the implementation of a gluten-free and casein-free diet was the most used intervention among the studies. Of the total, 10 studies showed a positive association of intervention with the evaluated results, while 8 did not find of a significant association. Conclusions: Although some authors report progress in the symptoms associated with autism in individuals with Autistic Spectrum Disorder undergoing nutritional interventions, there is little scientific evidence to support the use of nutritional supplements or dietary therapies in children and adolescents with autism.

RESUMO Objetivo: Identificar e analisar as evidências científicas de intervenções nutricionais realizadas em crianças e adolescentes com Transtorno do Espectro Autista. Fontes de dados: Realizou-se uma revisão sistemática nas bases de dados MEDLINE, Cochrane Library, Embase, LILACS, Google Acadêmico, PubMed, PsycINFO e Periódicos CAPES utilizando estratégia de busca abrangente para identificar estudos publicados entre janeiro de 2003 e março de 2018, em língua portuguesa, inglesa e espanhola. Foram incluídos estudos que descreveram intervenções nutricionais em crianças e adolescentes com Transtorno do Espectro Autista e avaliaram sintomas comportamentais e/ou sintomas gastrintestinais, sendo excluídos artigos de revisão e estudos que não incluíram um grupo controle em seu delineamento. Os estudos foram examinados para obter informações descritivas, e a qualidade de evidência foi avaliada por meio do Sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation). Síntese dos dados: Dezoito estudos foram incluídos na revisão (16 ensaios clínicos randomizados, um estudo de caso-controle e um ensaio clínico aberto). As intervenções e os resultados variaram, entretanto a implementação de uma dieta livre de glúten e caseína foi a intervenção mais utilizada entre os estudos. Do total, dez estudos encontraram associação positiva entre intervenção e resultados avaliados, enquanto oito não encontraram associação significativa. Conclusões: Embora alguns autores exponham progressos nos sintomas associados ao autismo em indivíduos com esse transtorno submetidos a intervenções nutricionais, há poucas evidências científicas para apoiar o uso destas em crianças e adolescentes com autismo.

Application and evaluation of mobile nutrition management service for breast cancer patients / 한국영양학회지

PURPOSE: This study evaluated the effects of nutrition management application in a mobile device on obesity management of patients with breast cancer.METHODS: Fifty subjects, who were breast cancer survivors, aged 30 years and older, participated in an obesity management program for four weeks. They were divided randomly into two groups: a control group (n = 25) and a treatment group (n = 25). The treatment group was provided an application for nutrition management and diet consultant, while the control group maintained their ordinary life without any nutrition management.RESULTS: The weight of the treatment group decreased by 0.8 kg, but the change was not significant. In contrast, the waist-hip ratio of the treatment group decreased significantly from 0.75 to 0.71 (p = 0.012). The Nutrition Quotients of the treatment group increased significantly from 61.3 to 69.6 points (p < 0.001), whereas that of the control group decreased significantly from 61.5 to 59.0 (p = 0.002).CONCLUSION: This mobile nutrition management application for breast cancer patients is effective in managing obesity and dietary habits. These results can be used as basic information to prepare an obesity management program for breast cancer patients.

Self-Reported Diet Management and Adherence to Dietary Guidelines in Korean Adults with Hypertension

BACKGROUND AND OBJECTIVES: Although dietary management is strongly recommended in patients with hypertension, little is known about how many manage their diet and follow the guidelines for hypertension. We investigated the prevalence of dietary management among adults with known hypertension and evaluated their compliance to the dietary guidelines.METHODS: Data from the Korea National Health and Nutrition Examination Survey 2013–2016 were used. Among 15,870 adults aged 30–79 years, 4,162 reported a physician-diagnosed hypertension. Diet management behavior was defined by self-report response. Actual dietary intake was assessed by a 24-hour dietary recall. Dietary quality was evaluated using the Korean Healthy Eating Index (KHEI).RESULTS: Among adults with hypertension, 28.0% reported that they were managing their diet. Those with hypertension consumed significantly less dietary sodium (p value<0.01), but also less potassium (p value<0.01), resulting in no difference of sodium-to-potassium ratio compared to those without hypertension (p value=0.66). Among those with hypertension, diet-managing adults had better KHEI score (66.9, p value<0.01) and consumed less sodium (3,354.3 mg, p value<0.01) than not-managing adults (63.6 score and 3,554.5 mg, respectively). However, total KHEI score was rather lower in those with hypertension (p value<0.01) than those without hypertension and their sodium intake was still over the recommended amount.CONCLUSIONS: More than two-thirds of Korean adults with hypertension did not manage their diet in daily life. More effective strategies are needed to increase the level of compliance with dietary recommendations for people with high blood pressure.

The glucose transporter type 1 deficiency syndrome / 中华神经科杂志

Glucose transporter type 1 deficiency syndrome is a rare neurometabolic disorder caused by mutations of the solute carrier family 2 facilitated glucose transporter member 1 (SLC2A1) gene, characterized by complex manifestations including early onset epilepsy, motor and mental retardation, and movement disorders and so on. Ketogenic-diet is most suitable therapy and should be commenced as early as possible because timing the initiation of the diet may prevent seizure, movement disorder, and cognitive impairment. This review aims to improve the clinicians′ understanding of glucose transporter type 1 deficiency syndrome to ensure the diagnosis as early as possible.
