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.

Diálogos entre educação popular e educação alimentar e nutricional: reflexões a partir das trajetórias de três docentes universitários / Dialogues between popular education and food and nutritional education: reflections from the trajectories of three university professors

Resumo Este ensaio explora as convergências e singularidades do diálogo entre a educação popular (EP) e a educação alimentar e nutricional (EAN) a partir de fragmentos biográficos do percurso formativo da graduação em Nutrição de três docentes universitários que constituíram as suas trajetórias acadêmico-profissional mediados pela Educação Popular. Inspirando-se na autobiografia, as narrativas revelaram que as indignações iniciais com as desigualdades sociais foram mobilizadoras do percurso formativo, possibilitando a compreensão dos fenômenos da fome, do sofrimento e do cuidado humano. Assim, o exercício de buscarem espaços e oportunidades na qual pudessem conhecer e experienciar o trabalho social em contextos de vulnerabilidades mostrou-se decisivo nas construções pessoais e profissionais, revelando as contradições dos modelos tradicionais de formação e foram o ponto de partida para a gênese do pensamento crítico. Assim, pretende-se oferecer pistas para compreender as interfaces entre EP e EAN, na convergência de ações em torno da luta contra a fome e pelo Direito à Alimentação, sem, entretanto, reduzir-se uma à outra, quando a alimentação e nutrição se projetam no horizonte das práticas.

Abstract This essay explores the convergences and singularities of popular education and Food and Nutrition Education based on biographical fragments of the undergraduate training program in Nutrition of three university professors who established their academic and professional trajectories at these crossroads of knowledge and actions mediated by popular education. Inspired by the autobiographical method, the narratives revealed that the initial indignations with social inequalities were mobilizing the routes in the formative path toward understanding hunger, suffering, and human care. To this end, seeking spaces and opportunities to learn about and experience social work in contexts of vulnerabilities was a decisive factor in their personal and professional constructions, revealing the contradictions of traditional training models and the starting point for the genesis of critical thinking. Thus, clues are offered to understand the interfaces of Popular Education (PE) and Food and Nutrition Education (FNE) in the converging actions around the fight against hunger and the right to food without, however, reducing one to the other when food and Nutrition are projected on the horizon of practices.

Percepção do peso corporal e dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos / Perception of body weight and difficulties encounteredby people with visual impairment in acquiring, preparing and consuming food

Objetivo: investigar a percepção do peso corporal e as dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos. Metodologia: estudo observacional transversal, com adultos e idosos com deficiência visual em Pelotas/RS, realizado no período de abril a maio de 2023. Foi utilizado um questionário composto de 42 itens. Os dados coletados foram analisados por análise descritiva e analítica, e apresentados como média ± desvio padrão ou percentual. Resultados: a amostra contou com 20 pessoas, predominantemente do sexo feminino e idosas. Em relação ao consumo alimentar, 50% dos participantes consomem feijão, 75% frutas e hortaliças, 50% bebidas adoçadas, biscoitos recheados e doces. Referente à percepção do peso corporal, percebeu-se que a maior parte do grupo sente que está acima do peso adequado e se sentem "insatisfeitos(as)". Sobre as dificuldades encontradas, 85% dos participantes relataram dificuldade extrema para identificar a validade dos alimentos, 70% para comprar alimentos frescos e perecíveis e 40% para usar a faca para cortar e descascar os alimentos. Conclusão: verificou-se que a maior parte do grupo sente que está acima do peso adequado e estão "insatisfeitos(as)" em relação ao peso corporal. Além disso, dependem de outra pessoa para escolher os alimentos a serem comprados, saber o prazo de validade, preparar alimentos que precisam ser porcionados, servir refeições no prato, cortar carnes, descascar vegetais e frutas, utilizar faca, entre outros. Esta dependência pode influenciar diretamente no seu consumo alimentar quando essas pessoas se encontram sozinhas, optando por consumir alimentos industrializados de fácil preparo ou prontos.

Objective: to investigate the perception of body weight and the difficulties encountered by people with visual impairments in acquiring, preparing and consuming food. Methodology: cross-sectional observational study, with adults and elderly people with visual impairment in Pelotas/RS, carried out from April to May 2023. A questionnaire composed of 42 items was used. The collected data were analyzed using descriptive and analytical analysis, and presented as mean ± standard deviation or percentage. Results: the sample included 20 people, predominantly female and elderly. Regarding food consumption, 50% of participants consume beans, 75% fruits and vegetables, 50% sweetened drinks, stuffed cookies and sweets. Regarding the perception of body weight, it was noticed that the majority of the group feels that they are overweight and feel "dissatisfied". Regarding the difficulties encountered, 85% of participants reported extreme difficulty in identifying the expiration date of food, 70% in purchasing fresh and perishable foods and 40% in using a knife to cut and peel food. Conclusion: it was found that the majority of the group feels that they are overweight and are "dissatisfied" with their body weight. Furthermore, they depend on someone else to choose the food to be purchased, know the expiration date, prepare food that needs to be portioned, serve meals on the plate, cut meat, peel vegetables and fruits, use a knife, among others. This dependence can directly influence their food consumption when these people are alone, choosing to consume easily prepared or ready-made processed foods.

A nomogram combining prognostic nutritional index and platelet lymphocyte ratio predicts postoperative pulmonary infection following D2 radical gastrectomy for gastric cancer.

Introduction: Introduction: the prognostic nutritional index (PNI) and platelet-lymphocyte ratio (PLR) have been found to correlate with outcomes following radical gastrectomy for gastric cancer (GC). Objectives: to construct a nomogram combining PNI and PLR for individually forecasting the risk of postoperative pulmonary infection (POI) following D2 radical gastrectomy for GC. Methods: retrospectively, clinical data was gathered from 404 patients treated with D2 radical gastrectomy for GC. The study used multivariate logistic regression analysis to screen independent risk factors for POI after surgery. Subsequently, a nomogram was developed based on the above factors to forecast the POI probability accurately. Results: the multivariate logistic regression analysis identified age, PNI, PLR, CA199 level, ASA score, and ICU treatment as independent risk variables for POI following D2 radical gastrectomy (p < 0.001 or 0.05). The nomogram's area under the receiver operating characteristic curve (AUC) for predicting the risk of POI was 0.736 (95 % confidence interval (CI) = 0.678-0.794). The nomogram was internally validated using the bootstrap approach, involving repeated sampling 1000 times. The result yielded a concordance index (c-index) of 0.707 (95 % CI = 0.705-0.709). The calibration curves demonstrated an excellent concordance between the predicted values of the nomogram and the observed values. The nomogram's clinical value was shown to be high using decision analysis curves. Conclusions: a nomogram combining PNI and PLR is a dependable tool for forecasting the probability of POI following D2 radical gastrectomy for GC.

Introducción: Introducción: se ha observado que el índice nutricional pronóstico (INP) y el cociente plaquetas/linfocitos (PLR) se correlacionan con los resultados tras la gastrectomía radical por cáncer gástrico (CG). Objetivos: diseñar un nomograma que combine el INP y la RPL para predecir individualmente el riesgo de infección pulmonar postoperatoria (POI) tras una gastrectomía radical D2 por CG. Métodos: de forma retrospectiva, se recopilaron datos clínicos de 404 pacientes tratados con gastrectomía radical D2 por CG. El estudio utilizó un análisis de regresión logística multivariante para detectar factores de riesgo independientes de IOP tras la cirugía. Posteriormente, se desarrolló un nomograma basado en los factores mencionados para pronosticar con precisión la probabilidad de POI. Resultados: el análisis de regresión logística multivariante identificó la edad, el INP, el PLR, el nivel de CA199, la puntuación ASA y el tratamiento en la UCI como variables de riesgo independientes para el POI tras la gastrectomía radical D2 (p < 0,001 o 0,05). El área bajo la curva ROC (característica operativa del receptor) AUC del nomograma para predecir el riesgo de POI fue de 0,736 (intervalo de confianza [IC] del 95 % = 0,678-0,794). El nomograma se validó internamente mediante el método bootstrap, que consiste en repetir el muestreo 1000 veces. El resultado fue un índice de concordancia (índice c) de 0,707 (IC del 95 % = 0,705-0,709). Las curvas de calibración demostraron una excelente concordancia entre los valores predichos del nomograma y los valores observados. El valor clínico del nomograma se demostró elevado mediante curvas de análisis de decisión. Conclusiones: un nomograma que combina INP y PLR es una herramienta fiable para predecir la probabilidad de POI tras gastrectomía radical D2 por CG.

Individualized nutritional intervention improves the nutritional status of liver cancer patients after transcatheter arterial chemoembolization.

Introduction: Introduction: to explore the effect of individualized nutritional intervention on the nutritional status of patients with liver cancer after transcatheter arterial chemoembolization (TACE). Methods: 56 patients who underwent TACE in our hospital from March 2022 to March 2023 were selected as the study subjects. The patients were randomly divided into a control group (28 cases) and an intervention group (28 cases). The control group received routine dietary intervention, while the intervention group received individualized nutritional intervention. We analyzed the body mass index (BMI), nutritional risk screening 2002 (NRS 2002), nutritional status, liver function status, and incidence of complications in two groups of patients before TACE, 3 days after TACE, and 1 month after TACE. Results: on the third day after TACE, the nutritional related indicators of both groups of patients showed a significantly decrease compared to those before TACE (p < 0.05), while the majority of liver function indicators significantly increased (p < 0.05). Compared with those at 3 days after TACE, the nutritional status of the intervention group patients significantly improved (p < 0.05) and liver function indicators significantly decreased (p < 0.05) 1 month after TACE. One month after TACE, all nutritional indicators in the intervention group were significantly higher than those in the control group (p < 0.05), and AST was significantly lower than that in the control group (p < 0.05). The incidence of gastrointestinal complications and electrolyte disorders in the intervention group were significantly lower than that in the control group (p < 0.05). Conclusion Individualized nutritional intervention can effectively improve nutritional status, improve liver function, and reduce the incidence of postoperative complications in liver cancer patients after TACE. It was worth promoting.

Introducción: Introducción: explorar el efecto de la intervención nutricional individualizada sobre el estado nutricional de los pacientes con cáncer de hígado después de la quimioembolización arterial (TACE). Métodos: se seleccionaron como sujetos de estudio 56 pacientes sometidos a TACE en nuestro hospital entre marzo de 2022 y marzo de 2023. Los pacientes se dividieron aleatoriamente en un grupo de control (28 casos) y un grupo de intervención (28 casos). El grupo de control recibió una intervención dietética rutinaria, mientras que el grupo de intervención recibió una intervención nutricional individualizada. Se analizó el índice de masa corporal (IMC), el cribado del riesgo nutricional 2002 (NRS 2002), el estado nutricional, el estado de la función hepática y la incidencia de complicaciones en dos grupos de pacientes antes de la TACE, 3 días después de la TACE y 1 mes después de la TACE. Resultados: al tercer día después de la TACE, los indicadores relacionados con la nutrición de ambos grupos de pacientes mostraron una disminución significativa en comparación con los de antes de la TACE (p < 0.05), mientras que la mayoría de los indicadores de la función hepática aumentaron significativamente (p < 0.05). En comparación con los 3 días después de la TACE, el estado nutricional de los pacientes del grupo de intervención mejoró significativamente (p < 0.05) y los indicadores de la función hepática disminuyeron significativamente (p < 0.05) 1 mes después de la TACE. Un mes después de la TACE, todos los indicadores nutricionales del grupo de intervención fueron significativamente superiores a los del grupo de control (p < 0.05), y la AST fue significativamente inferior a la del grupo de control (p < 0.05). La incidencia de complicaciones gastrointestinales y trastornos electrolíticos en el grupo de intervención fue significativamente inferior a la del grupo de control (p < 0.05). Conclusión: la intervención nutricional individualizada puede mejorar eficazmente el estado nutricional, mejorar la función hepática y reducir la incidencia de complicaciones postoperatorias en pacientes con cáncer de hígado tras TACE. Merece la pena promoverlo.

Nutritional status and its relationship with COVID-19 prognosis in hemodialysis patients.

Introduction: Introduction: among the groups more affected by the COVID-19 pandemic were patients undergoing chronic hemodialysis (HD) treatment due to their comorbidities, advanced age, impaired innate and adaptive immune function, and increased nutritional risk due to their underlying inflammatory state. All of these factors contribute to a higher risk of severe complications and worse outcomes compared to the general population when infected with SARS-CoV-2. Objective: the objective of this study was to describe the nutritional characteristics of and their potential association with the prognosis of COVID-19 in patients undergoing chronic HD treatment. Method: a descriptive, retrospective, observational design. All cases of COVID-19 in patients undergoing chronic treatment at the Hemodialysis Unit of Hospital de Manises, Valencia, Spain, from the start of the pandemic to before vaccination were included. Results: for that, 189 patients were studied, who received chronic HD treatment in the hospital unit, 22 patients were diagnosed with COVID-19 (12 %) in that period. The mean age was 71 years, 10 were women, the Charlson index was 6.59 points, diabetes mellitus 10, vintage HD 51.6 months, 2 patients had previously received a currently non-functioning kidney transplant, 16 had arteriovenous fistula as vascular access, and 6 had central vascular access. The mean dialysis session time was 220.14 minutes and the initial value of the single dose of the Kt/V pool was 1.7. 16 patients had body composition measurement, a strong association (p < 0.05) was identified between mortality and BMI, as well as mortality and FTI. Furthermore, the differences between deceased and surviving groups in the serum levels of various variables related to nutritional status were analyzed, finding significant differences with p < 0.05 in the value of triglycerides and ferritin. Conclusions: higher body mass index and higher body fat content, along with lower baseline levels of triglycerides and ferritin, were significantly associated with higher COVID-19 mortality in patients on chronic hemodialysis. These findings suggest that the initial nutritional status of these patients can significantly influence the prognosis of SARS-CoV-2 infection.

Introducción: Introducción: entre los grupos más afectados por la pandemia de COVID-19 se encuentran los pacientes en tratamiento crónico de hemodiálisis (HD) por sus comorbilidades, edad avanzada, deterioro de la función inmune innata y adaptativa, y mayor riesgo nutricional por su estado inflamatorio de base. Todos estos factores contribuyen a un mayor riesgo de complicaciones graves y peores resultados en comparación con la población general cuando se infectan con SARS-CoV-2. Objetivo: el objetivo de este estudio es describir las características nutricionales y su potencial asociación con el pronóstico de COVID-19 en pacientes en tratamiento crónico de HD. Método: diseño observacional retrospectivo y descriptivo. Se incluyeron todos los casos de COVID-19 en pacientes en tratamiento crónico en la Unidad de Hemodiálisis del Hospital de Manises, Valencia, desde el inicio de la pandemia hasta antes de la vacunación. Resultados: de 189 pacientes que recibieron tratamiento de HD crónica en la unidad hospitalaria, 22 pacientes fueron diagnosticados con COVID-19 (12 %) en ese período. La edad media fue de 71 años, 10 eran mujeres, índice de Charlson de 6,59 puntos, diabetes mellitus 10, tiempo en diálisis 51,6 meses, 2 pacientes habían recibido previamente un trasplante renal actualmente no funcionante, 16 tenían fístula arteriovenosa como acceso vascular, y 6 tenían acceso vascular central. El tiempo medio de la sesión de diálisis fue de 220,14 minutos y el valor inicial de la dosis única del pool de Kt/V fue de 1,7. Tenían medición de la composición corporal 16 pacientes, se identificó una fuerte asociación (p < 0,05) entre mortalidad e IMC, así como mortalidad y FTI. Además las diferencias entre los grupos de fallecidos y sobrevivientes en los niveles séricos de diversas variables relacionadas con el estado nutricional fueron analizados, encontrando diferencias significativas con p < 0,05 en el valor de triglicéridos y ferritina. Conclusiones: un índice de masa corporal más alto y un mayor contenido de grasa corporal, junto con niveles basales más bajos de triglicéridos y ferritina, se asocian significativamente a una mayor mortalidad por COVID-19 entre los pacientes en hemodiálisis crónica. Estos hallazgos sugieren que el estado nutricional inicial de estos pacientes puede influir significativamente en el pronóstico de la infección por SARS-CoV-2.

No se encontró diferencias estadísticamente significativas en cuanto a las variables de estudio según rangos de edad (< 19 años vs >=19 años).Conclusiones: La composición corporal permitió cuantificar las reservas corporales del organismo de los estudiantes, el porcentaje de estos componentes corporales fue variable y depende del sexo. Un bajo porcentaje de estudiantes presentaron adecuados consumos de frutas, vegetales y fibra, los hombres tienen un mayor nivel de actividad física.(AU)

Introduction: In the current epidemiological and nutri-tional context, knowledge about the eating habits, lifestyles,and nutritional conditions of young university students is ur-gently needed.Objective: To identify body composition, eating habits,and physical activity in university students. Materials and Methods: Observational-cross-sectionalstudy. The population consisted of university students between16 and 25 years of age (n = 118). The variables studied were:age, sex, weight, height, BMI, body fat mass, skeletal musclemass, visceral fat, waist circumference, dietary habits, andphysical activity. Body composition was measured by anthro-pometry and bioelectrical impedance. Food consumption wasobtained with the Block Screening Questionnaire. The shortInternational Physical Activity Questionnaire (IPAQ) was usedto assess physical activity. Chi-Square and T-Student tests wereused as hypothesis contrasts. To determine associations be-tween variables, a p-value <0.05 was considered statisticallysignificant.Results: Skeletal muscle mass was higher in males (38%)than in females (25%), while body fat was higher in females(37%) than in males (24%). These differences were statisti-cally significant. Regarding dietary habits, 19% had a diet highand very high in fat, and less than 1% had normal consump-tion of fruits, vegetables, and fiber. Regarding physical activity,46% indicated high physical activity, 52% moderate, and2.5% low activity. It was observed that men had more highphysical activity than women; however, women had moremoderate and low physical activity than men (p = 0.0299). Nostatistically significant differences were found for the studyvariables according to age ranges.Conclusions: Body composition was variable and sex-de-pendent. A minimum percentage of university students hadadequate intakes of fruits, vegetables, and fiber. Men had ahigher level of physical activity than women.(AU)

Asociación de fuerza prensil y extensores de rodilla con estado nutricional de adultos mayores pertenecientes a la comunidad / Association of grip strength and knee extensors with nutritional status of community-dwelling older adults

Antecedentes y objetivo: Determinar la asociación de fuerza prensil de mano y extensores de rodilla con el estado nutricional de adultos mayores de la comunidad. Material y métodos: Estudio observacional transversal. Se analizó peso y talla de 847 adultos mayores según índice de masa corporal y se clasificaron en cuatro categorías nutricionales según el Ministerio de Salud de Chile. Se evaluó la fuerza prensil de mano y extensores de rodilla para ambas extremidades. La fuerza fue normalizada por masa corporal y se utilizó la correlación de Spearman entre índice de masa corporal y fuerza muscular. Resultados: La muestra fue de 582 mujeres y 265 hombres con edad promedio de 71,72±7,09. Las mujeres presentaron un índice de masa corporal de 30,03±5,48 y los hombres 27,64±4,05, la categoría más numerosa fue normopeso (n = 288) y la menor bajo peso (n = 74). La fuerza prensil de mano presentó mayor correlación que extensores de rodilla, específicamente, fuerza prensil de mano derecha (r: -0,40). La mayor correlación y significancia la presentó la categoría obesa para todas las mediciones de fuerza, resultando la fuerza prensil de mano derecha como la más alta (r: -0,29). Conclusiones: El aumento del estado nutricional de los adultos mayores influye negativamente sobre la fuerza muscular. La mejor asociación entre índice de masa corporal y fuerza muscular fue la prensión de mano derecha. Resalta el hallazgo del aumento de la esperanza de vida a medida que disminuye el IMC de la muestra. Futuros estudios deberían generar percentiles y valores normalizados en población chilena.(AU)

Aim: To determine the association of hand grip strength and knee extensor strength with the nutritional status of community-dwelling older adults. Material and methods: Observational cross-sectional study. Weight and height of 847 older adults were analyzed according to body mass index and classified into four nutritional categories according to the Chilean Ministry of Health. Hand grip and knee extensors strength for both extremities were evaluated. Strength was normalized by body mass. Spearman's correlation between body mass index and muscle strength was used. Results: The sample was 582 women, 265 men and an average age of 71.72±7.09. The women had a BMI of 30.03±5.48 and the men of 27.64 ± 4.05, the most numerous category was normal weight (n = 288) and the lowest low weight (n = 74). Hand grip strength presented a higher correlation than knee extensors, specifically, right hand grip strength (r: −0.40). The highest correlation and significance were presented by the obese category for all strength measurements, with right hand grip strength being the highest (r: −0.29). Conclusions: The increase in the nutritional status of older adults has a negative influence on muscle strength. The best association between body mass index and muscle strength was the right hand grip. The finding of the increase in life expectancy as the nutritional status of the sample decreases stands out. Future studies are needed to generate percentiles and normalized values in the Chilean population.(AU)

¿Cómo detectar a los pacientes mayores no institucionalizados en riesgo de malnutrición durante su hospitalización? Comparación de 8 herramientas de cribado de malnutrición o de riesgo nutricional / How to detect non-institutionalized older patients at risk of malnutrition during their hospitalization? Comparison of 8 screening tools for malnutrition or nutritional risk

Antecedentes: La prevalencia de malnutrición es elevada entre la población mayor. El ingreso hospitalario es una ventana de oportunidad para su detección. Objetivo: Valorar la concordancia de distintas escalas nutricionales en pacientes hospitalizados.Método: Estudio prospectivo en pacientes mayores de 65años no institucionalizados ingresados en un servicio de Medicina Interna. Se compararon 5 encuestas de cribado de malnutrición (MNA, MST, MUST, NRS-2000 y CONUT) y 3 encuestas de cribado de riesgo nutricional (SCREEN3, 8 y 14). Como patrón de referencia se utilizó la definición de malnutrición de la Iniciativa Global para el Liderazgo en Malnutrición (GLIM). Resultados: Se incluyeron 85 pacientes (37% mujeres, mediana de edad 83años). El 48% (IC95%: 38-59%) de los pacientes fueron clasificados como malnutridos según criterios GLIM. La escala SCREEN3 fue la más sensible (93%; IC95%: 87-98) y MUST la más específica (91%; IC95%: 85-99). La escala más eficaz para excluir la sospecha de malnutrición fue SCREEN3 (LR− 0,17; IC95%: 0,05-0,53) y la mejor para confirmarla fue MST (LR+ 7,08; IC95%: 3,06-16,39). La concordancia entre las distintas escalas fue baja o muy baja, con índices kappa entre 0,082 y 0,465.Conclusiones: Se precisa un abordaje integral para detectar la malnutrición en adultos mayores ingresados. Las escalas más sensibles son más útiles en el cribado inicial. Las herramientas de riesgo nutricional podrían ser eficaces en esta etapa. En un segundo paso se debe confirmar la malnutrición de acuerdo con criterios establecidos como los de la GLIM.(AU)

Background: The prevalence of malnutrition is high among the elderly population. Hospital admission is a window of opportunity for its detection. Objective: To assess the concordance of different nutritional scales in hospitalized patients. Methods: Prospective study in non-institutionalized patients over 65years of age admitted to an internal medicine department. Five malnutrition screening surveys (MNA, MST, MUST, NRS-2000 and CONUT) and three nutritional risk screening surveys (SCREEN3, 8 and 14) were compared. As gold standard we use the Global Leadership Initiative for Malnutrition (GLIM) definition of malnutrition. Results: Eighty-five patients (37% female, median age 83years) were included. Forty-eight percent (95%CI: 38-59%) of patients were classified as malnourished according to GLIM criteria. The SCREEN3 scale was the most sensitive (93%; 95%CI: 87-98) and MUST the most specific (91%; 95%CI: 85-99). The most effective scale for excluding suspected malnutrition was SCREEN3 (LR− 0.17; 95%CI: 0.05-0.53) and the best for confirming it was MST (LR+ 7.08; 95%CI: 3.06-16.39). Concordance between the different scales was low or very low with kappa indices between 0.082 and 0.465. Conclusions: A comprehensive approach is needed to detect malnutrition in hospitalized patients. More sensitive scales are more useful in initial screening. Nutritional risk tools could be effective at this stage. In a second step, malnutrition should be confirmed according to established criteria such as GLIM.(AU)

Association between nutritional risk status and both diaphragmatic dysfunction and diaphragm atrophy in medical intensive care unit patients / Asociación entre el estado de riesgo nutricional y la disfunción diafragmática y la atrofi a del diafragma en pacientes de la unidad de cuidados intensivos médicos

Aim: critical illness often leads to malnutrition and diaphragmatic dysfunction (DD), common in intensive care units (ICU). Ultrasonography (US) is a potent tool for detecting DD. This study examines the connection between malnutrition risk and DD in ICU patients using ultrasonographic diaphragm measurements in medical ICU patients. Methods: we assessed nutritional risk using risk screening tools and mid-upper arm circumference measurements (MUAC). Diaphragm atrophy (DA) and DD were evaluated by measuring diaphragmatic excursion (DE), thickness, and thickening fraction (TF) by US. We then compared these diaphragmatic measurements in patients based on their nutritional risk scores. Results: of the fifty patients studied, 54 % to 78 % were at risk of malnutrition, 28 % exhibited diaphragm atrophy (DA), and 24 % showed DD upon ICU admission. Malnutrition risk diagnosed by all nutritional risk screening tools was significantly more frequent in patients with DD, while diagnosed by MUAC was considerably higher in patients with DA. A total of 16 patients (32 %) died during their ICU stay, with DD, DA, and malnutrition risks (as identified by the mNUTRIC Score) being more prevalent among non-survivors (p < 0.05). Malnutrition risk (as determined by the mNUTRIC Score) was an independent risk factor for DD [OR (95 % CI): 6.6 (1.3-34), p = 0.03]. Conclusion: malnutrition risk may be significantly associated with DD and DA in medical ICU patients upon ICU admission.(AU)

Objetivo: las enfermedades graves a menudo conducen a desnutrición y disfunción diafragmática (DD), comunes en las unidades de cuidados intensivos (UCI). La ultrasonografía (US) es una herramienta poderosa para detectar la DD. Este estudio examina la conexión entre riesgo de desnutrición y DD en pacientes de UCI utilizando mediciones ultrasonográficas del diafragma.Métodos: evaluamos el riesgo nutricional utilizando herramientas de evaluación de riesgos y mediciones de la circunferencia del brazo en su punto medio superior (MUAC). La atrofia del diafragma (DA) y la DD se evaluaron midiendo la excursión diafragmática (DE), el grosor y la fracción de engrosamiento (TF) por ecografía. Luego, comparamos estas mediciones diafragmáticas en pacientes según sus puntuaciones de riesgo nutricional. Resultados: de los cincuenta pacientes estudiados, entre el 54 % y el 78 % estaban en riesgo de desnutrición, el 28 % presentaban atrofia del diafragma (DA) y el 24 % mostraban DD al ingreso en la UCI. El riesgo de desnutrición diagnosticado por todas las herramientas de evaluación del riesgo nutricional fue significativamente más frecuente en los pacientes con DD, mientras que el diagnosticado por el MUAC fue considerablemente mayor en los pacientes con DA. Un total de 16 pacientes (32 %) fallecieron durante su estancia en la UCI, siendo la DD, la DA y los riesgos de desnutrición (según lo identificado por la puntuación mNUTRIC) más prevalentes entre los no sobrevivientes (p < 0,05). El riesgo de desnutrición (según lo determinado por la puntuación mNUTRIC) fue un factor de riesgo independiente de la DD [OR (95 % CI): 6,6 (1,3-34), p = 0,03]. Conclusión: en este estudio se encontró una asociación significativa entre el riesgo de desnutrición y la disfunción diafragmática, así como con la atrofia diafragmática al ingreso en la UCI.(AU)

Alteraciones somatométricas y menor puntaje aPGar en recién nacidos indígenas / Somatometric alterations and lower APGAR score in indigenous newborns

Introducción: la población indígena es vulnerable y poco se conoce sobre sus indicadores somatométricos y APGAR al nacimiento. Objetivo: explorar la asociación de la condición de recién nacido indígena (RNI) sobre parámetros somatométricos y APGAR al nacimiento. Métodos: estudio transversal exploratorio que empleó el registro de recién nacidos (RN) de una clínica privada. La condición de RNI se determinó por la condición indígena materna. Se consideraron la puntuación APGAR al primer minuto y los indicadores nutricionales derivados del peso, la talla y los perímetros. El análisis estadístico empleó regresiones logísticas. Resultados: el análisis exploratorio involucró a 7413 RN (1,8 % de RNI). El 52 % de los RN eran de sexo masculino y el 8,1 % fueron pretérmino (< 37 semanas). Los RNI, respecto a los RN no indígenas, presentaron mayor riesgo de desnutrición (8 % vs. 6,3 %; p < 0,001), mayor exceso de peso (7,3 % vs. 1,8 %; p < 0,001), menor perímetro cefálico (33,6 cm vs. 34,1 cm; p = 0,017), menor perímetro abdominal (30,9 cm vs. 31,5 cm; p = 0,011) y bajo puntaje APGAR < 7 (8,7 % vs. 1,2 %). La condición de indígena se asoció de manera independiente con el bajo peso (< 2500 g) al nacimiento (OR: 0,4; IC 95 %: 0,2; 0,9), perímetro cefálico en exceso (OR: 2,7; IC 95 %: 1,5; 4,7) y puntaje de APGAR < 7 puntos (OR: 8,3; IC 95 %: 4,2; 16,5). Conclusiones: la condición de indígena se asocia con indicadores que impactan negativamente en la salud de los recién nacidos, como son el perímetro cefálico y el bajo desempeño en la escala APGAR. Estos resultados deben tomarse como un llamado para mejorar la atención prenatal de la población indígena.(AU)

Introduction: the indigenous population is vulnerable and there is limited understanding of their somatometric indicators and APGAR score at birth. Aim: the objective of the study was to explore the association of the condition of indigenous newborn (INB) on somatometric parameters and APGAR score at birth. Methods: this study employed an exploratory cross-sectional design, utilizing the registry of newborns (NB) from a private clinic. The APGAR score at one minute after birth, as well as nutritional indicators derived from measurements of weight, height, and perimeters, were taken into consideration. The statistical analysis involved the use of logistic regressions. Results: the analysis included 7413 NB (1.8 % INB), 52 % were male and 8.1 % were born preterm (gestational age < 37 weeks). In comparison to non-indigenous NB, the INB group showed a higher risk of malnutrition (8 % vs. 6.3 %; p < 0.001), a greater prevalence of excess weight (7.3 % vs. 1.8 %; p < 0.001), smaller head circumference (33.6 cm vs. 34.1 cm; p = 0.017), smaller abdominal circumference (30.9 cm vs. 31.5 cm; p = 0.011), and a higher occurrence of low APGAR scores (< 7) (8.7 % vs. 1.2 %; p < 0.001). Furthermore, the indigenous condition was independently associated with low birth weight (< 2.500 g) (OR, 0.4; 95 % CI, 0.2; 0.9), excess head circumference (OR, 2.7; 95 % CI, 1.5; 4.7), and APGAR score < 7 points (OR, 8.3; 95 % CI, 4.2; 16.5). Conclusions: the indigenous condition was associated with factors that have adverse effects on the health of NB, including reduced head circumference and suboptimal performance on the APGAR scale. These results emphasize the importance of improving access to and quality of prenatal healthcare services for indigenous communities.(AU)

Evolución nutricional durante las primeras etapas del trasplante de precursores hematopoyéticos: importancia del ángulo de fase / Nutritional evolution during the early stages of hematopoietic stem cell transplantation: importance of the phase angle

Introducción: el objetivo de este estudio es comparar los cambios en la antropometría, dinamometría e indicadores de la impedancia bioeléctrica (BIA) de pacientes sometidos a trasplante de precursores hematopoyéticos (TPH) autólogo y alogénico luego del periodo de acondicionamiento y una semana postrasplante, así como evaluar si estos cambios precoces se asocian con el desarrollo de complicaciones posteriores. Metodología: estudio de cohorte prospectivo. El estado nutricional se evaluó mediante antropometría, dinamometría y BIA en tres momentos diferentes definidos: T1, momento del ingreso; T2, después del periodo de acondicionamiento mieloablativo; y T3, día + 8 post-TPH. Resultados: un total de 40 pacientes fueron evaluados, 17 recibieron TPH autólogo (TAU) y 23, TPH alogénico (TAL). Los pacientes con TAL presentaron una mayor mortalidad y estadía hospitalaria en comparación con los pacientes con TAU. Aquellos que desarrollaron enfermedad injerto contra huésped (EICH) presentan un menor ángulo de fase (AF) que aquellos que no desarrollaron esta complicación (T2: AF TAL con EICH 4,8° vs. AF TAL sin EICH 5,5°, p = 0,007). Los pacientes que fallecieron durante la estadía hospitalaria son todos del grupo TAL y tenían un AF menor a 5° en T3. Peso, índice de masa corporal (IMC) e índice de masa libre de grasa (IMLG) no mostraron un impacto significativo y todos ellos estaban influidos por el agua corporal total. Conclusiones: la evaluación nutricional precoz de estos pacientes mediante AF parece prometedora, ya que no se ve alterado por la retención de agua y se puede evaluar antes que los cambios antropométricos sucedan.(AU)

Introduction: the aim of this study is to compare the changes in anthropometry, dynamometry and bioelectrical impedance analysis (BIA) of patients undergoing autologous and allogeneic hematopoietic stem cell transplantation (HSCT) after the conditioning period and one-week post-transplantation, and to assess whether these early changes are associated with the development of later complications. Methods: prospective cohort study. Nutritional status was assessed by anthropometry, dynamometry and BIA at three different defined times: T1, time of admission; T2, after the myeloablative conditioning period; and T3, day + 8 post-HSCT.Results: forty patients were evaluated, 17 received autologous HSCT (TAU) and 23 received allogeneic HSCT (TAL). Patients with TAL had higher mortality and hospital stay compared to patients with TAU. Those who developed graft versus host disease (GVHD) presented a lower phase angle (PA) than those who did not develop this complication (T2: TAL PA with GVHD 4.8° vs TAL PA without GVHD 5.5°, p = 0.007). The patients who died during the hospital stay are all from the TAL group and had PA less than 5° at T3. Weight, body mass index (BMI) and fat-free mass index (FMI) did not show a significant impact, and all of them were influenced by total body water. Conclusions: early nutritional evaluation of these patients by phase angle seems promising, since it is not altered by water retention and can be evaluated before anthropometric changes occur.(AU)
