Dietitians' practices in dialysis units in Brazil: nutritional assessment and intervention / Práticas de nutricionistas em unidades de diálise no Brasil: avaliação e intervenção nutricionais

ABSTRACT Introduction: The importance of dietitians in dialysis units is indisputable and mandatory in Brazil, but little is known about the practices adopted by these professionals. Objective: To know practices adopted in routine nutritional care, focusing on nutritional assessment tools and treatment strategies for people at risk or diagnosed with malnutrition. Methodology: Electronic questionnaire disseminated on social media and messaging applications. It included questions that covered dietitians' demographic and occupational profile characteristics and of the dialysis unit, use and frequency of nutritional assessment tools, nutritional intervention strategies in cases of risk or diagnosis of malnutrition, prescription and access to oral supplements. Results: Twenty four percent of the Brazilian dialysis units (n = 207) responded electronically. The most used nutritional assessment tools with or without a pre-established frequency were dietary surveys (96%) and Subjective Global Assessment (83%). The strategies in cases of risk or presence of malnutrition used most frequently (almost always/always) were instructions to increase energy and protein intake from foods (97%), and increasing the frequency of visits (88%). The frequency of prescribing commercial supplements with standard and specialized formulas was quite similar. The availability of dietary supplements by the public healthcare system to patients varied between regions. Conclusion: Most dietitians use various nutritional assessment tools and intervention strategies in cases of risk or malnutrition; however, the frequency of use of such tools and strategies varied substantially.

Resumo Introdução: A importância da atuação do nutricionista em unidades de diálise é indiscutível e obrigatória no Brasil, porém pouco sabemos sobre as práticas adotadas por esses profissionais. Objetivo: Conhecer práticas adotadas na rotina dos atendimentos nutricionais, com foco nas ferramentas de avaliação nutricional e nas estratégias de tratamento das pessoas com risco ou diagnóstico de desnutrição. Metodologia: Questionário eletrônico divulgado em mídias sociais e aplicativos de mensagens. Incluiu questões que abrangiam características do perfil demográfico e ocupacional do profissional e da unidade de diálise, utilização e frequência de ferramentas de avaliação nutricional, estratégias de intervenção nutricional em casos de risco ou diagnóstico de desnutrição e prescrição e acesso a suplementos alimentares orais. Resultados: Foram recebidos eletronicamente o equivalente a 24% das unidades de diálise brasileiras (n = 207). As ferramentas de avaliação nutricional mais utilizadas com ou sem frequência pré-estabelecida foram inquéritos dietéticos (96%) e Avaliação Global Subjetiva (83%). As estratégias em casos de risco ou presença de desnutrição utilizadas com mais frequência (quase sempre/sempre) foram a orientação de incremento energético e proteico por meio de alimentos (97%) e o aumento da periodicidade das visitas (88%). A frequência de prescrição de suplemento industrializado de fórmula padrão e especializada foi bastante semelhante. A disponibilização de suplementos alimentares pelo Sistema Único de Saúde aos pacientes variou entre as regiões. Conclusão: A maior parte dos nutricionistas utiliza diversas ferramentas de avaliação nutricional e estratégias de intervenção em casos de risco ou desnutrição, porém a frequência de utilização de tais ferramentas e estratégias foi bastante variada.

Food consumption among adolescents and biological and adiposity outcomes / Consumo alimentar entre adolescentes e desfechos biológicos e de adiposidade

Objective: to investigate the association between macronutrient consumption and biological and adiposity indicators in adolescents. Methods: A total of 77 adolescents were evaluated in relation to anthropometric measurements, sexual maturation, body composition, sociodemographic variables, and food composition. Results: the percentage of lipids in relation to total energy intake was positively related to age (ß = 1.33; 95% CI = 0.37 to 2.28), and inversely related to sexual maturation (ß = -2.44; 95% CI =-4.68 to ­ 0.20). Girls had a higher consumption of lipids than boys (ß= 4.59; 95% CI = 0.62 to 8.57). Age was positively associated with the consumption of saturated (ß = 0.62; 95% CI =0,30 to 0,94) and monounsaturated fatty acids (ß=0.48; 95% CI = 0.16 to 0.79). Sexual maturation was inversely associated with the consumption of saturated (ß=-1.7; 95% CI = -2.46 to -0.95), monounsaturated (ß = -1.59; 95% CI = -2.34 to -0.84), and trans fatty acids (ß = -0.32; 95% CI = -0.34 to -0.00). Fat mass showed a positive association with the consumption of saturated (ß = 0.18; 95%CI = 0.03 to 0.32) and monounsaturated fatty acids (ß = 0.23; 95% CI =0.091 to 0.38). Conclusion: The consumption of lipids was positively related to age and inversely related to sexual maturation; fat mass was positively associated with the consumption of saturated and monounsaturated fatty acids. The findings of this study reinforce the concern regarding a high-fat diet among adolescents, especially older girls.

Objetivo: investigar a associação entre consumo de macronutrientes, indicadores biológicos e de adiposidade em adolescentes. Métodos: foram avaliados 77 adolescentes em relação às medidas antropométricas, maturação sexual, composição corporal, sociodemográficas e composição alimentar. Resultados: O percentual de lipídios em relação à ingestão energética total foi positivamente relacionado à idade (ß = 1,33; IC95% 0,37 a 2,28) e inversamente relacionado à maturação sexual (ß = -2,44; IC95% -4,68 a ­0,20). As meninas apresentaram maior consumo desses lipídios quando comparadas aos meninos (ß= 4,59; IC95% 0,62 a 8,57). A idade associou-se positivamente ao consumo de ácidos graxos saturados (ß = 0,62; IC95% 0,30 a 0,94) e monoinsaturados (ß = 0,48; IC95% 0,16 a 0,79). A maturação sexual foi inversamente associada ao consumo de ácidos graxos saturados (ß=-1,7; IC95% -2,46 a -0,95), monoinsaturados (ß = -1,59; IC95% -2,34 a -0,84) e trans (ß = -0,32; IC95% -0,34 a -0,00). A massa gorda apresentou associação positiva com o consumo de ácidos graxos saturados (ß = 0,18; IC95% 0,03 a 0,32) e monoinsaturados (ß = 0,23; IC95% 0,091 a 0,38). Conclusão: O consumo de lipídios esteve positivamente relacionado com a idade e inversamente relacionado com a maturação sexual; a massa gorda foi positiva associada ao consumo de ácidos graxos saturados e monoinsaturados. Os achados desta pesquisa reforçam a preocupação quanto a uma alimentação hiper lipídica entre adolescentes, especialmente entre as meninas com maior idade.

Composição da gordura corporal em pacientes com doenças inflamatórias intestinais: um estudo comparativo entre dobras cutâneas e ultrassonografia / Body fat composition in patients with inflammatory bowel diseases: a comparative study between skinfolds and ultrasonography

ABSTRACT Background: Inflammatory bowel diseases (IBD) are associated with important changes in nutritional status. Objective: The aim of the study was to compare body fat composition between two anthropometric methods: skinfolds and ultrasonography, in patients with IBD. Methods: Single-center cross-sectional study with IBD patients in remission or active disease. For the agreement analysis between the body fat assessment methods, the Bland Altman method was used. Results: A total of 101 patients with IBD were included, 75 with Crohn's disease and 26 with ulcerative colitis. Approximately 56% of the patients with Crohn's disease and 65.4% of those with ulcerative colitis had a body fat composition above normal levels, with no significant difference between the diseases (P=0.63). The Bland-Altman concordance analysis showed that the methods for assessing the percentage of fat by the adipometer and ultrasound were not in full agreement (P=0.001), despite both presented good correlation (CC 0.961; P=0.000). Conclusion: The analysis of body fat percentage in patients with IBD was different between the skinfolds and ultrasound. Both methods can be used to assess the of body fat percentage of patients with IBD. However, monitoring of body fat sequentially and longitudinally should always be performed using the same method throughout the disease course. Prospective longitudinal studies are warranted to precisely define the role of these two methods of measuring body composition in patients with IBD.

RESUMO Contexto: As doenças inflamatórias intestinais (DII) estão associadas a alterações importantes no estado nutricional. Objetivo: O objetivo do estudo foi comparar a composição da gordura corporal entre dois métodos antropométricos: dobras cutâneas e ultrassonografia, em pacientes com DII. Métodos: Estudo transversal de centro único com pacientes com DII em remissão ou doença ativa. Para a análise de concordância entre os métodos de avaliação da gordura corporal foi utilizado o método de Bland-Altman. Resultados: Foram incluídos 101 pacientes com DII, 75 com doença de Crohn e 26 com colite ulcerativa. Aproximadamente 56% dos pacientes com doença de Crohn e 65,4% daqueles com colite ulcerativa apresentaram composição de gordura corporal acima dos níveis normais, sem diferença significativa entre as doenças (P=0,63). A análise de concordância de Bland-Altman mostrou que os métodos de avaliação do percentual de gordura pelo adipômetro e ultrassonografia não foram totalmente concordantes (P=0,001), apesar de ambos apresentarem boa correlação (CC 0,961; P=0,000). Conclusão: A análise do percentual de gordura corporal em pacientes com DII foi diferente entre as dobras cutâneas e a ultrassonografia. Ambos os métodos podem ser usados para avaliar o percentual de gordura corporal de pacientes com DII. Entretanto, o monitoramento da gordura corporal de forma sequencial e longitudinal deve ser sempre realizado utilizando o mesmo método durante todo o curso da doença. Estudos longitudinais prospectivos são necessários para definir com precisão o papel desses dois métodos de medição da composição corporal em pacientes com DII.

Estado nutricional, força muscular e capacidade funcional em portadores de mieloma múltiplo / Nutritional status, muscle strength and functional capacity in patients with multiple myeloma

O mieloma múltiplo é uma neoplasia maligna caracterizada pela proliferação clonal de plasmócitos na medula óssea. O objetivo deste trabalho foi avaliar as possíveis associações entre o estado nutricional, força muscular e capacidade funcional de pacientes ambulatoriais portadores de mieloma múltiplo. Trata-se de estudo transversal realizado em amostra não probabilística de pacientes com mieloma múltiplo atendidos no Hospital das Clínicas, em Goiânia. Os dados foram coletados entre agosto e dezembro de 2015, utilizando-se de entrevistas e informações dos prontuários. O estado nutricional foi avaliado aplicando-se a Avaliação Subjetiva Global Produzida pelo Próprio Paciente; a força muscular medida por meio da Força do Aperto de Mão e a capacidade funcional, pela Escala de Performance de Karnofsky. O estudo foi aprovado pelo Comitê de Ética e Pesquisa do referido hospital. Foram avaliados 52 pacientes, em que 48,1% estavam desnutridos, 30,8% apresentavam baixa força muscular e 73,1%, comprometimento da capacidade funcional. A força muscular e a capacidade funcional foram menores nos desnutridos. Observou-se que aqueles que utilizavam corticoides apresentaram 18% menos chance de se tornarem desnutridos (OR=0,18; IC=0,05-0,62; p=0,011) porém, é importante considerar as possíveis causas de viés; por outro lado, os pacientes com baixa força muscular ou faziam quimioterapia apresentaram, aproximadamente, quatro vezes mais chances de desnutrição, respectivamente (OR=3,46; IC=0,99-12,08; p=0,047) (OR=3,64; IC=1,13-11,69; p=0,027). Concluiu-se que a desnutrição é comum nos pacientes portadores de mieloma múltiplo, indicando a necessidade premente de intervenção nutricional apropriada e precoce.

Multiple myeloma is a malignant neoplasm characterized by the clonal proliferation of plasma cells in the bone marrow. The objective of this study was to evaluate possible associations between nutritional status, muscle strength and functional capacity of outpatients with multiple myeloma. This is a cross-sectional study carried out on a non-probabilistic sample of patients with multiple myeloma treated at Hospital das Clínicas, in Goiânia. Data were collected between August and December 2015, using interviews and information from medical records. Nutritional status was assessed using the Patient Generated Subjective Global Assessment; muscular strength measured using Hand Grip Strength and functional capacity, using the Karnofsky Performance Scale. The study was approved by the Ethics and Research Committee of that hospital. 52 patients were evaluated, of which 48.1% were malnourished, 30.8% had low muscle strength and 73.1% had impaired functional capacity. Muscle strength and functional capacity were lower in malnourished individuals. It was observed that those who used corticosteroids were 18% less likely to become malnourished (OR=0.18; CI=0.05-0.62; p=0.011), however, it is important to consider the possible causes of bias; on the other hand, patients with low muscle strength or undergoing chemotherapy were approximately four times more likely to be malnourished, respectively (OR=3.46; CI=0.99-12.08; p=0.047) (OR=3.64; CI=1.13-11.69; p=0.027). It was concluded that malnutrition is common in patients with multiple myeloma, indicating the pressing need for appropriate and early nutritional intervention.

Índice de massa corporal e desfechos clínicos: um estudo retrospectivo durante a pandemia de Covid-19 / Body mass index and clinical outcomes: a retrospective study in Covid-19 / Índice de masa corporal y resultado clínico: un estudio retrospectivo durante la pandemia de Covid-19

A COVID-19 é uma doença respiratória aguda provocada pela infecção do vírus SARS-CoV-2, que pode causar uma grave insuficiência respiratória hipoxêmica, complicações e mortes, principalmente na população com condições crônicas de saúde. Os mecanismos pelos quais a obesidade pode aumentar a gravidade da COVID-19 incluem mecanismos físicos, inflamação crônica e uma função imunológica prejudicada. Além disso, o índice de massa corporal elevado é um fator de risco para várias condições médicas que têm sido sugeridas para aumentar o risco de gravidade da COVID-19. Objetivo: analisar a associação entre o índice de massa corporal e desfechos clínicos dos casos confirmados de COVID-19. Metodologia: Estudo transversal, com coleta de dados de prontuários, conduzido de março de 2020 a dezembro 2021. Foram analisados os registros de prontuários, exames bioquímicos e de imagem de pacientes internados com COVID-19 em três hospitais da cidade de Francisco Beltrão (PR). As variáveis analisadas foram o diagnóstico nutricional, idade, sexo, necessidade de internação em UTI, comorbidades, dias de hospitalização, complicações, exames laboratoriais e desfecho. Os critérios para inclusão no estudo foram, pacientes hospitalizados com diagnóstico para COVID-19, com presença de diagnóstico nutricional relatado. Resultados: No ano de 2020 foram analisados 292 prontuários e no ano de 2021 foram 860 prontuários. Destes, somente 413 possuíam diagnóstico nutricional, sendo assim incluídos no presente estudo. Foram classificados como peso normal 78 (18,9%), com sobrepeso 153 (37%)e como obeso 182 (44,1%) participantes. A maior prevalência de obesidade foi encontrada no sexo feminino (52,5%), portadores de diabetes (27,6%), pacientes com estado geral comprometido (67,9%), que apresentaram complicações pulmonares (54,5%) e arritmias (23%). A média de idade encontrada em pacientes com obesidade foi mais jovem (55,54) em comparação com os classificados com sobrepeso (59,08) e normal (62,51). Observou-se que quanto maior o IMC menor foram os valores encontrados para idade (rho = -0,190), leucócitos (rho = -0,109), ureia (rho = -0,145) e D-dímero (rho = -0,155). Conclusão: Este estudo fornece evidências de que o sobrepeso e/ou obesidade então associadas a um pior quadro clínico durante a internação dos pacientes com COVID-19. Em relação a frequência de óbito, não houve diferença estatística em relação ao diagnóstico nutricional.

COVID-19 is an acute respiratory disease caused by SARS-CoV-2 virus infection, which can cause severe hypoxemic respiratory failure, complications, and deaths, especially in the population with chronic health conditions. The mechanisms by which obesity may increase the severity of COVID-19 include physical mechanisms, chronic inflammation, and impaired immune function. In addition, high body mass index is a risk factor for several medical conditions that have been suggested to increase the risk of COVID-19 severity. Objective: to analyze the association between body mass index and clinical outcomes of confirmed cases of COVID-19. Methodology: Cross-sectional study, with data collection from medical records, conducted from March 2020 to December 2021. The records of medical records, biochemical and imaging tests of patients hospitalized with COVID-19 in three hospitals in the city of Francisco Beltrão (PR) were analyzed. The variables analyzed were nutritional diagnosis, age, gender, need for ICU admission, comorbidities, days of hospitalization, complications, laboratory tests and outcome. The inclusion criteria for the study were, hospitalized patients with diagnosis for COVID-19, with presence of nutritional diagnosis reported. Results: In the year 2020, 292 medical records were analyzed and in the year 2021 there were 860 medical records. Of these, only 413 had nutritional diagnosis, thus being included in this study. Were classified as normal weight 78 (18.9%), overweight 153 (37%), and obese 182 (44.1%) participants. The highest prevalence of obesity was found in females (52.5%), patients with diabetes (27.6%), patients with impaired general condition (67.9%), who presented pulmonary complications (54.5%) and arrhythmias (23%). The mean age found in obese patients was younger (55.54) compared to those classified as overweight (59.08) and normal (62.51). It was observed that the higher the BMI the lower were the values found for age (rho = -0.190), leukocytes (rho = -0.109), urea (rho = -0.145) and D-dimer (rho = -0.155). Conclusion: This study provides evidence that overweight and/or obesity then associated with a worse clinical picture during hospitalization of patients with COVID-19. Regarding the frequency of death, there was no statistical difference in relation to nutritional diagnosis.

Conclusión: Este estudio proporciona evidencia de que el sobrepeso y/u obesidad se asocia con una peor condición clínica durante la hospitalización de pacientes con COVID-19. En cuanto a la frecuencia de muerte, no hubo diferencia estadística en relación al diagnóstico nutricional.

Analysis of muscle mass by computed tomography in patients with head and neck cancer: a prospective study / Análise da massa muscular por tomografia computadorizada em pacientes com câncer de cabeça e pescoço: um estudo prospectivo

Abstract Objective: To evaluate the preoperative muscle mass of patients with head and neck cancer (HNC) with computed tomography (CT), comparing the results obtained through analysis of cross-sectional areas at the level of the third lumbar vertebra (L3) with those obtained through analysis of cross-sectional areas at the levels of the third cervical and fourth thoracic vertebrae (C3 and T4, respectively). Materials and Methods: A total of 63 patients with HNC were evaluated preoperatively. Using CT, we assessed muscle mass at L3, as well as at C3 and T4. Results: Most (73.0%) of the patients had low muscle mass at L3, whereas 50.8% had a normal body mass index. The cross-sectional area at L3 correlated strongly with those at C3 and T4 (r = 0.831 and r = 0.763, respectively; p < 0.001 for both). In addition, the muscle mass index at L3 correlated strongly with those at C3 and T4 (r = 0.781 and r = 0.715, respectively; p < 0.001 for both). Conclusion: Low muscle mass appears to be highly prevalent in patients with HNC. Measurements at C3 and T4 could represent alternative means of assessing muscle mass in such patients.

Resumo Objetivo: Avaliar e comparar a massa muscular de pacientes com câncer de cabeça e pescoço (CCP) durante o período pré-operatório com tomografia computadorizada (TC), por meio da análise das áreas transversais no nível da terceira vértebra lombar (L3) em comparação com níveis cervical (C3) e torácico (T4). Materiais e Métodos: Sessenta e três pacientes com CCP foram avaliados no pré-operatório. A TC foi utilizada para avaliar a massa muscular de L3, assim como as secções transversais de C3 e T4. Resultados: A maioria dos pacientes (73,0%) tinha baixa massa muscular analisada pela TC de L3, mas índice de massa corpórea normal (50,8%). Também foi observada forte correlação entre as áreas e o índice de massa muscular (IMM) de L3 com C3 (área: r = 0,831, p < 0,001; IMM: r = 0,781, p < 0,001) e T4 (área: r = 0,763, p < 0,001; IMM: r = 0,715, p < 0,001). Conclusão: A baixa massa muscular é altamente prevalente em pacientes com CCP. As análises de TC em C3 e T4 podem representar opção para avaliar a massa muscular em pacientes com CCP.

Relação entre o estado nutricional e prática regular de atividade física de idosos residentes em uma instituição privada no município de Taubaté/SP / Relationship between nutritional status and regular practice of physical activity of elderly residents in a private institution in the municipality of Taubaté/SP

Objetivo ­ Avaliar a relação do estado nutricional de idosos institucionalizados com a prática de atividade física. Com o aumento da população idosa, cresce a importância das condições de dependência, que em algum momento irão apresentar a necessidade de cuidados específicos. Diante disso, é necessário que tenham acompanhamento a todo momento ou na maioria do tempo, o que muitas vezes resulta na institucionalização destes idosos, por diversos motivos, como a indisponibilidade de algum familiar para acompanhá-lo ou a falta de recursos para oferecer os cuidados necessários. Nestas instituições, o idoso é observado de maneira multidisciplinar, onde definem-se suas necessidades visando melhorar as condições de vida deste paciente. Neste contexto, a avaliação do estado nutricional é de extrema importância tendo em vista que sua inadequação pode refletir na piora de sua saúde de modo geral e aumentar o risco de mortalidade, e a avaliação pode facilitar a tomada de decisões e intervenções que previnam a evolução ou o desenvolvimento de patologias futuras e, por conseguinte, impedir que os idosos venham a se debilitar. Métodos ­ A metodologia empregada engloba uma entrevista padronizada, aplicação da Mini Avaliação Nutricional ­ MAN, do Questionário Internacional de Atividade Física (IPAQ) versão curta e avaliação antropométrica. Resultados ­ Foi possível evidenciar a prevalência dos idosos residentes na instituição sendo do sexo masculino, e o estado nutricional em relação ao IMC foi de sobrepeso/obesidade e com nível de atividade física classificado como sedentário. Conclusão ­ Sugerem-se novos estudos para determinar as causas e o impacto do sobrepeso/obesidade e sedentarismo em idosos institucionalizados com o intuito de direcionar os cuidados e a atenção à saúde do idoso, ao envelhecimento com qualidade de vida. Por fim, diante da amostra insuficiente os resultados do estudo indicaram que a institucionalização do idoso é uma questão de extenso debate, uma vez que a equipe de saúde que assiste o idoso precisa de conhecimentos, aptidão, tempo e qualidades para que possam suprir as necessidades dos idosos.

Malnutrición asociada con factores sociodemográficos en adultos mayores de Medellín (Colombia) / Malnutrition Associated with Sociodemographic Factors in Older Adults in Medellin, Colombia / Má nutrição associada a fatores sociodemográficos em idosos em Medellín-Colômbia

Introducción: los adultos mayores (AM) presentan riesgo de malnutrición (exceso o déficit de peso) debido a cambios fisiológicos, alimentarios, psicológicos y sociales derivados del envejecimiento. Objetivo: estimar la frecuencia de malnutrición por antropometría y el Mini Nutritional Assessment (MNA) en AM de Medellín (Colombia) y explorar su asociación con factores sociodemográficos. Materiales y métodos: estudio trans- versal con 1187 adultos ≥60 años, derivado del proyecto Propuesta técnica para el desarrollo del perfil de seguridad alimentaria y nutricional 2015, realizado en hogares de zona urbana y rural. Se tomaron como variables independientes las sociodemográficas, y como dependientes, las antropométricas y el MNA. La asociación entre malnutrición y variables sociodemográficas se determinó por modelos de regresión logística binaria y multinomial. Resultados: 65.2 % fueron mujeres, la edad promedio fue 70.0 ± 8.0 años; 61.5 % de estrato socioeconómico bajo, 65.9 % con nivel educativo primaria o inferior. Según el índice de masa corporal, 57.6 % presentó malnutrición, 20.8 % déficit de peso y 36.8 % exceso de peso. Según el MNA, 41.4 % tenía riesgo de desnutrición, y 5.4 %, desnutrición. Ambas condiciones se presentaron con mayor frecuencia en mujeres (OR = 2.0; IC95 %: 1.5-2.6), edades ≥75 años (OR = 1.7; IC95 %: 1.2-2.4), estrato socioeconómico bajo (OR = 3.2; IC95 %: 1.5-6.8), del área rural (OR = 1.7; IC95 %: 1.1-2.5), con estudios de primaria (OR = 2.1; IC95 %: 1.1-4.4) o sin educación (OR = 3.4; IC95 %: 1.5-7.5). Conclusión: la malnutrición en AM de Medellín es elevada y constituye un problema de salud pública, más frecuente en mujeres, edades avanzadas, zonas rurales, estratos socioeconómicos bajos y niveles educativos inferiores; condiciones que deben tenerse en cuenta para la implementación de políticas públicas

Introduction: Older adults (OA) are at risk of malnutrition (overnutrition or undernutrition) due to physio- logical, feeding, psychological, and social changes associated with aging. This study aimed to estimate the frequency of malnutrition using anthropometry and the Mini-Nutritional Assessment (MNA) among OA in Medellin, Colombia, and explore the association of malnutrition with sociodemographic factors. Methods: A cross-sectional study derived from the Technical Proposal for the Development of the Food and Nutrition Security Profile, 2015 was performed with 1187 adults aged ≥60 years old among urban and rural households. The sociodemographic characteristics were considered as independent variables, and anthropometric and MNA data were defined as dependent variables. To establish the association between malnutrition and sociodemographic variables, binary and multinomial logistic regression models were used. Results: The average age of the participants was 70.0 ± 8.0 years old; 65.2% were women; 61.5% were of low socioeconomic status; and 65.9% attained primary education or lower. Based on body mass index, 57.6% had malnutrition, 20.8% were undernutrition, and 36.8% were overweight/obese. According to the MNA, 5.4% had malnutrition, while 41.4% were at risk of malnutrition. Both conditions occurred more frequently in women (OR = 2.0; 95% confidence interval [CI]: 1.5­2.6), aged ≥75 years old (OR = 1.7; 95% CI: 1.2­2.4), with low socioeconomic status (OR = 3.2; 95% CI: 1.5­6.8), from rural areas (OR = 1.7; 95% CI: 1.1­2.5), with primary education (OR = 2.1; 95% CI: 1.1­4.4) or no education (OR = 3.4; 95% CI: 1.5­7.5). Conclusion: Malnutrition among OA in Medellin, Colombia, is high, especially among women living in rural areas with low socioeconomic status and education level. The study findings indicate a public health problem. These conditions must be considered in the implementation of public policies

Introdução: os idosos (AM de adultos mayores) estão sob risco de má nutrição (excesso de peso ou desnu- trição) devido às alterações fisiológicas, dietéticas, psicológicas e sociais decorrentes do envelhecimento. O objetivo deste estudo foi estimar a frequência de má nutrição por antropometria e pelo Mini Nutritional Assessment (MNA) em AM de Medellín-Colômbia e explorar sua associação com fatores sociodemográficos. Materiais e métodos: estudo transversal com 1187 adultos ≥ 60 anos, derivados do projeto Proposta técnica para elaboração do perfil de Segurança Alimentar e Nutricional 2015, realizado em domicílios de áreas urbanas e rurais. Variáveis sociodemográficas foram consideradas como variáveis independentes e as variáveis antropométricas e MNA como variáveis dependentes. A associação entre a má nutrição e as variáveis sociodemográficas foi determinada por modelos de regressão logística binária e multinomial. Resultados: 65.2% eram mulheres, idade média 70.0 ± 8.0 anos; 61.5% de estrato socioeconômico baixo, 65.9% com nível de escolaridade fundamental ou inferior. De acordo com o índice de massa corporal (IMC), 57.6% apresentaram desnutrição, 20.8% magreza e 36.8% excesso de peso. Segundo o MNA, 41.4% estavam em risco de desnutrição e 5.4% já apresentavam desnutrição. Ambas as condições ocorreram com maior frequência em mulheres (or = 2.0; Ic 95%: 1.5-2.6), idade ≥ 75 anos (or = 1.7; Ic 95%: 1.2-2.4), baixo nível socioeconômico (or = 3.2; Ic 95%: 1.5-6.8), da zona rural (or = 1.7; Ic 95%: 1.1-2.5), com ensino fundamental (or = 2.1; Ic 95%: 1.1-4.4) ou sem escolaridade (or = 3.4; Ic 95%: 1.5-7.5).

Situación Nutricional de embarazadas y lactantes haitianos atendidos en el CESFAM "Los Castaños" de la comuna de La Florida, Región Metropolitana, Chile

En Chile, al 31 de diciembre del 2020 un 12,5% de los extranjeros eran de nacionalidad haitiana. Se desconoce el estado nutricional (EN) en embarazadas y lactantes; así como también la prevalencia de lactancia materna exclusiva (LME) de la población haitiana en Chile. Los objetivos de este trabajo fueron comparar: (i) el EN de embarazadas haitianas y chilenas, (ii) el EN de lactantes y (iii) la duración de la LME en hijos de madres haitianas y chilenas. Para esto se analizó la base de datos de la población haitiana y chilena atendidos entre los años 2016-2019 en el Centro de Salud Familiar (CESFAM) "Los Castaños" ubicado en la comuna de La Florida. En la etapa pre-gestacional, las embarazadas haitianas presentaron mayor prevalencia de bajo peso en comparación a embarazadas chilenas (p= 0,0003), mientras que al término del embarazo presentaron una mayor prevalencia de estado nutricional normal (p= 0,0001) y menor prevalencia de obesidad (p= 0,0001). Respecto al estado nutricional de los lactantes, sólo se observaron diferencias en el primer mes de vida, donde un 82% de los lactantes haitianos tenían un EN normopeso en comparación al 24% en los lactantes chilenos (p= 0,0001). No se observaron diferencias significativas en la prevalencia de LME hasta los 6 meses entre lactantes haitianos y chilenos (35,3% vs 30%, respectivamente). Es importante mencionar que ninguno de los dos grupos de lactantes cumplió con la meta establecida por la Organización Mundial de la Salud (OMS) que propone LME en los primeros seis meses de vida hasta al menos 50%. En conclusión, se evidencian diferencias en el EN de las embarazadas y lactantes de ambos países, mientras que la prevalencia de LME en ambos grupos fue similar.

In Chile, until December 31st, 2020, 12.5% of foreign residents were from Haiti. The nutritional status (NS) in pregnant women and infants is unknown; as well as the prevalence of exclusive breastfeeding (EBF) of the Haitian population residing in Chile. This study aimed to compare: (i) the NS of Haitian and Chilean pregnant women, (ii) the NS of infants, and (iii) the duration of EBF in children of Haitian and Chilean mothers. We analyzed the database of the Haitian and Chilean population attended between the years 2016-2019 at the Primary Care Health Center (CESFAM) "Los Castaños" located in the commune of La Florida. During the pregestational stage, the Haitian pregnant women had a higher prevalence of low weight compared to the Chilean pregnant women (p= 0,0003), whereas, at the end of the pregnancy, they had a higher prevalence of normal nutritional status (p= 0,0001) and a lower prevalence of obesity and a tendency at the end of pregnancy. Whereas at the end of the pregnancy, Chilean women had a higher prevalence of obesity. Regarding the nutritional status of the infants, differences were only observed in the first month of life, where 82% of Haitian infants had a normal weight compared to 24% of Chilean infants (p= 0.0001). No significant differences were observed in the prevalence of EBF up to 6 months between Haitian and Chilean infants (35.3% vs. 30%, respectively). It is important to mention that neither of the two groups of infants met the goal established by the World Health Organization (WHO) that proposes EBF for the first six months of life up to at least 50%. In conclusion, there are differences in the NE of pregnant and lactating women in both countries, while the prevalence of EBF in both groups was similar.

Association between phase angle of bioelectrical impedance analysis and nutritional parameters in older adults

INTRODUCTION: Phase angle (PhA) is a Bioelectrical impedance analysis (BIA) parameter representing an indicator of cellular health and has been suggested as a biomarker of nutritional status. OBJECTIVE: To evaluate the association between PhA and nutritional parameters in older adults. METHODS: A cross-sectional study was conducted with community-dwelling older adults. Body mass index (BMI), arm muscle circumference (AMC), calf circumference (CC), body fat percentage (BF%), appendicular skeletal muscle mass (ASMM), serum albumin, mini-nutritional assessment (MNA), and PhA were assessed. Kolmogorov­Smirnov test, Spearman's correlation coefficient, chi-square test, and Poisson regression models were performed. RESULTS: 144 participants were included in the study, and most of them were female, aged ≥80 years, and underweight. Most older adults with lower PhA were women, aged range 80­89 years, and with reduced ASMM (p<0.05). PhA presented a significant correlation with age (r=­0.417; p<0.001), ASMM (r=0.427; p<0.001), AMC (r=0.195; p=0.019) and BF% (r=­0.223; p=0.007). Older adults with lower PhA present reduced ASMM (PR: 1.25; 95%CI: 1.04­1.50), and hypoalbuminemia (PR: 1.50; 95%CI: 1.11­2.03). CONCLUSION: PhA is related to commonly nutritional indicators used in clinical practice and could be an important biomarker of muscle mass reserves in community-living older adults of both sexes.

Nutritional status and food environment of the elderly population residing in tea gardens of a block of Darjeeling District, West Bengal, India

Objectives: In India, poverty, illiteracy, and difficult terrains make the tea garden elderly population more vulnerable to malnutrition. The food environment shows the interface through which consumers interact with their food system. Hence, the present study was done to assess the nutrition status and identify the sociodemographic and food environmental factors affecting the nutritional status of the elderly population residing in tea gardens of Naxalbari block, Darjeeling district, West Bengal, India. Materials and Methods: A community-based cross‑sectional study was conducted in all tea gardens of Naxalbari block, Darjeeling, from March 2022 to September 2022, among older people aged 60 years and above selected by simple random sampling. Using the predesigned, pretested questionnaire, the Mini Nutritional Assessment tool for nutritional assessment and the elderly population’s perceived food environment was determined based on five points Likert’s scale. Perceived food environment clusters were identified using a two‑stage cluster analysis. Binary logistic regression was used to determine predictors of nutritional status. Results: Out of the 294 study participants, the majority of 190 (64.6%) of the older people were at the risk of malnutrition, 18 (6.1%) malnourished, and 86 (29.3%) had normal nutritional status. Binary logistics regression showed older people who were illiterate (adjusted odds ratio [AOR] 14.864; 95% confidence interval [CI]; 4.311–51.457) and not working (AOR 3.775; 95% CI; 1.753–8.128) had significantly higher odds of being undernourished. Older people who perceived a favorable food environment (AOR 0.408; 95% CI; 0.214–0.775) had significantly lesser odds of being undernourished. Conclusion: Tea garden older population is at higher risk of malnutrition. Illiteracy, working status, and perceived favorable food environment plays important role in altering the nutritional status of the elderly. Prior interventions such as awareness regarding food nutrition and developing elderly friendly food environment are needed.

Applicability of Modified Pediatric Nutritional Risk Screening Tool in children with cerebral palsy / 中华实用儿科临床杂志

Objective:To explore the scheme of assigning rational scores to the Modified Pediatric Nutritional Risk Screening Tool for children with cerebral palsy(CP) at different Gross Motor Function Classification System(GMFCS) levels.Methods:The clinical data of 360 children with CP hospitalized in the Department of Children′s Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January to October 2019 were analyzed retrospectively.All the CP children at different GMFCS levels who met the inclusion criteria were subject to nutrition screening and assessment by using the Modified Pediatric Nutritional Risk Screening Tool and the Subjective Global Nutritional Assessment(SGNA) scale.The distribution of malnutrition rates assessed by the SGNA scale among the children at different GMFCS levels was examined.Data between groups were compared by the χ2 test.Children at different GMFCS levels were divided into different subgroups according to the statistical difference.Then, 0 or 1 score was assigned to the Modified Pediatric Nutritional Risk Screening Tool in different subgroups, and different combinations were formed.The nutritional risk screening results of different combinations were evaluated by using the SGNA scale assessment results as a reference. Results:In children with CP, the risk detection rate and incidence rate of malnutrition were 58.1%(209/360) and 36.9%(133/360), respectively.There was no significant difference in the incidence rate of malnutrition between GMFCS Ⅱ and GMFCS Ⅲ, as well as between GMFCS Ⅳ and GMFCS Ⅴ(all P>0.05). Therefore, children with CP were divided into 3 subgroups, namely, group Ⅰ, group Ⅱ to Ⅲ, and group Ⅳ to Ⅴ.Different CP disease scores were given to the Modified Pediatric Nutritional Risk Screening Tool in 3 subgroups, forming 3 different protocols[protocol 1 (0, 0, 1 point); protocol 2(0, 1, 1 point); current protocol (1, 1, 1 point)]. Taking the SGNA scale assessment results as a reference, the sensitivity of protocol 1, protocol 2 and current protocol were 85.7%, 92.5%, and 93.2% respectively.The specificity protocol 1, protocol 2 and current protocol were 81.1%, 78.0%, and 62.6%, respectively.And the Youden indexes of above three protocols were 0.668, 0.705, and 0.558, respectively.The Youden index of protocol 2 was relatively high. Conclusions:The Modified Pediatric Nutritional Risk Screening Tool can effectively identify the risk of malnutrition in children with CP.The scheme of assigning 0 points to children with GMFCS grade Ⅰ and 1 point to children with GMFCS grade Ⅱ to Ⅴ is more reasonable.

Application of NRS 2002 and PG-SGA in Patients With Gastrointestinal Malignancies / 胃肠病学

Background:At present,domestic guidelines and consensus recommend the use of nutritional risk screening 2002(NRS 2002)and patient-generated subjective global assessment(PG-SGA)for nutritional risk screening and assessment of patients with gastrointestinal cancer during the perioperative period.However,PG-SGA has higher professional requirements,complex content and time-consuming.In the current busy situation of medical staff,NRS 2002 is more used for screening alone.Aims:To explore the consistency of NRS 2002 and PG-SGA in the assessment of nutritional status and clinical outcomes in patients with gastrointestinal malignancies,and to explore the accuracy of screening using NRS 2002 alone,so as to provide guidance for the establishment of clinical nutritional screening and assessment standards.Methods:A retrospective analysis was conducted on 157 patients with gastrointestinal malignancies who underwent radical operation in the Department of Gastrointestinal Surgery of Xiangya Hospital,Central South University from January 2020 to October 2022.Nutritional screening and evaluation were performed by NRS 2002 and PG-SGA scales and demographic data and nutrition-related laboratory indicators were collected to observe short-term postoperative clinical outcomes.Results:Patients with nutritional risk or malnutrition had lower body mass index(BMI),lymphocytes and prealbumin(P<0.05).The correlation and consistency of NRS 2002 and PG-SGA scales were good(r=0.728,κ=0.46)and the areas under the curve(AUC)for predicting postoperative complications were 0.691 and 0.702,respectively.In addition,nutritional risk and postoperative complications were significantly increased in patients with malnutrition(P<0.05).Conclusions:Therefore,gastrointestinal surgeons can only use NRS2002 to perform nutritional screening of patients and make corresponding nutritional treatment according to the screening results in the case of busy clinical work.

Advances in nutrition support during perioperative period of adult liver transplantation / 中华消化外科杂志

The most common complication in patients with end-stage liver disease is mal-nutrition, which is caused by the metabolic disorders of sugar, protein and fat for the metabolic dys-function of liver during the perioperative period of liver transplantation. Nutritional support is very important during the liver transplantation.Perioperative nutritional support can improve the nutri-tional status of patients, increase the chance of liver transplantation, reduce postoperative mortality and improve outcome. By reviewing the recent interventions of perioperative nutrition support for liver transplantation, and analyzing nutritional screening and nutritional assessment tools and their advantages and disadvantages, the authors emphasize the rational assessment of early nutrition, provide reasonable and personalized parenteral and enteral nutrition support, especially for energy, protein and other nutrients. We also emphasize the importance of long-term reasonable nutrition support, monitoring and diet nutrition education in order to provide reference and suggestion for improving the nutritional status of liver transplantation patients and to provide evidence-based basis for constructing standardized perioperative nutrition support program of liver transplantation.

Association between prognostic nutritional index and cognitive impairment in maintenance hemodialysis patients / 中华肾脏病杂志

Objective:To explore the relationship between prognostic nutritional index (PNI) and cognitive impairment (CI) in maintenance hemodialysis (MHD) patients.Methods:It was a multicenter cross-sectional study that included adult patients who received MHD treatment at 18 hemodialysis centers in Guizhou province from June to October 2020 as the study subjects. Cognitive function was assessed with the mini-mental state examination score. According to the scale score, the patients were divided into CI group (≤27 scores) and non-CI group (>27 scores), and the differences between the two groups were compared. The patients were divided into Q1 (PNI<38.0), Q2 (38.0≤PNI<40.4), Q3 (40.4≤PNI<43.0), and Q4 (PNI≥43.0) groups based on the PNI quartiles. The PNI was estimated based on the serum albumin and lymphocyte count. Multivariate logistic regression analysis was used to analyze the correlation between PNI and CI, and subgroup analysis was conducted.Results:A total of 1 740 MHD patients were enrolled in the study, with 1 021 males (62.9%) and 719 females (37.1%). The age was (55±15) years old. There were 411 patients (23.6%) with CI. The age, C-reactive protein, and the proportions of females, current smoking/drinking and diabetes in the CI group were significantly higher than those in the non-CI group, and the education level, blood lymphocyte count, blood prealbumin, serum albumin, serum creatinine, blood uric acid and PNI were significantly lower than those in the non-CI group (all P<0.05). The risk of CI in Q1 group was 1.88 times higher than that of Q4 group after adjusting for confounding factors such as sex, age, body mass index, education level, comorbidities, current smoking/drinking, dialysis age and C-reactive protein ( OR=1.88, 95% CI 1.17-2.30, P=0.008). Subgroup analysis showed that there was an interaction between age and PNI on CI ( P=0.040 for interaction). Q1 group in the patients aged 18 to 45 years old had a higher risk of CI compared to Q4 group ( OR=3.30, 95% CI 1.19-9.10). Conclusions:Low PNI significantly increases the risk of CI in MHD patients, in particularly in the patients aged <45 years old.

Progress on nutritional assessment and nutritional support for liver transplant recipients / 器官移植

Patients with end-stage liver disease after liver transplantation constantly suffer from malnutrition due to primary diseases and transplantation-related factors. Malnutrition will worsen clinical condition of the patients, increase the incidence of complication, length of hospital stay and medical expense after transplantation, and lower the survival rate. Sufficient nutritional support at all stages of liver transplantation is of significance. Accurate assessment of nutritional status and timely intervention are prerequisites for perioperative nutritional treatment in liver transplantation. In this article, the latest nutritional risk screening indexes and evaluation tools, nutritional support methods and other perioperative nutritional intervention measures for liver transplantation were reviewed, aiming to deepen the understanding and cognition of perioperative nutritional therapy for liver transplantation and provide reference for improving nutritional status and clinical prognosis of liver transplant recipients.

Nutritional status of patients with pulmonary tuberculosis and anti-tuberculosis treatment effect / 中国热带医学

@#Abstract: Objective To investigate the nutritional status of patients with pulmonary tuberculosis and its effects on conventional anti-tuberculosis treatment, so as to provide a basis for improving the efficacy of conventional treatment of pulmonary tuberculosis. Methods The relevant data of 168 patients with pulmonary tuberculosis admitted to Suining Central Hospital from April 2020 to April 2022 were retrospectively analyzed. Nutritional status of the patients before treatment was investigated using the Mini Nutritional Assessment (MNA) score, and the influencing factors of nutritional status before treatment were analyzed. Therapeutic effects of anti-tuberculosis drugs in the non-nutritional risk group and the nutritional risk group were comparatively analyzed. Results Among the 168 patients, 64 were assessed as having good nutritional status before treatment, 59 had the risk of malnutrition and 45 were malnourished according to the MNA score. Univariate analysis and linear regression analysis showed that age, underlying diseases, and clinical symptoms were factors affecting the MNA score before treatment (t=3.173, 3.718, 2.018, P all<0.05); whereas gender and education level were not factors affecting MNA score before treatment (t=0.065, 0.059, P all>0.05). According to the MNA score before treatment, the patients were dividedinto a non-nutritional risk group (MNA score > 23.5) and a nutritional risk group (MNA score ≤23.5). The negative conversion rate of sputum bacteria, effective rate of focal absorption in the non-nutritional risk group were 92.19% (59/64)and90.63% (58/64) , respectively, which were significantly higher than corresponding 79.85% (82/104)and76.92% (80/104) in the nutritional risk group. The drug resistance rate, adverse reaction rate, and average treatment cost of the no nutritional risk group and nutritional risk group were 7.81% (5/64) and 21.15% (12/104), 15.63% (10/64) and 31.73% (33/104), (0.62±0.13) million yuan and (0.89±0.26) million yuan, respectively, with significant differences (χ2=5.228, 5.071, 7.685, 5.396, 7.728, P all<0.05). Conclusions Patients with pulmonary tuberculosis exhibit poor nutritional status before treatment. The patients’nutritional status is easily affected by age, underlying diseases, and clinical symptoms, thereby affecting the effect of anti-tuberculosis treatment. Therefore, early nutritional intervention for tuberculosis patients should be recommended in order to prevent malnutrition and enhance the effectiveness of anti-tuberculosis treatment.
