Nutritional factors and pressure injury risk in hospitalised patients post-stroke.

OBJECTIVE: This study aimed to analyse the nutritional factors and pressure injury (PI) risk in hospitalised patients post-stroke. METHOD: The research employed a descriptive observational method in which patients ≥18 years of age were followed for six days. Nutritional evaluation was based on anthropometric and dietary factors. The nutritional risk was assessed via anthropometric measurements, Braden nutrition subscale and daily dietary intake. PI risk was evaluated through the Braden Scale. The Wilcoxon test, paired t-test, and Kruskal-Wallis test were applied and corrected with Bonferroni correction or analysis of variance, followed by the post hoc Tukey test. RESULTS: During their hospital stays, the participating 59 patients had an increase in sensory perception (p=0.02) and nutrition (p=0.005) scores. It was observed that patients at high risk of PI did not meet daily nutritional recommendations for calories, proteins, carbohydrates, lipids and micronutrients (zinc, selenium and copper) compared with patients at low-to-moderate risk. Weight (p<0.001), body mass index (p<0.001), calf (p=0.01) and arm (p=0.04) circumferences, and subscapular (p=0.003) and triceps (p<0.001) skinfolds decreased during the six days of hospitalisation. CONCLUSION: From the findings of this study, it was concluded that nutritional factors, such as unmet recommended daily nutritional requirements of macronutrients and micronutrients, and nutritional status are associated with a higher risk of developing a PI.

Night fasting as an alternative to improve nutritional support and glycaemic control in hospitalised patients with exclusive enteral nutrition.

BACKGROUND: Enteral nutrition (EN) assists in the nutritional status of hospitalised patients unable to feed orally. The aim of this study was to determine which method-continuous EN or discontinuous EN, a diet in which the infusion is discontinued for 4h during the night,-is more effective in meeting nutrient recommendations and improving glycaemic control and biochemical parameters related to protein anabolism. METHODS: Patients were divided into two groups: discontinuous (EN administered in mL/h, 18h/day, 4-h night fasting) and continuous (EN administered in mL/h, 22h/day). All patients with EN receive the diet over a 22-h daily period, in which the diet is suspended for two hours/day for daily hospital routines such as bathing, and physiotherapy, and followed for seven days. Evaluated data: prescribed and administered volume, calories, protein, and fibre; capillary blood glucose; erythrogram; serum albumin. RESULTS: 52 patients were followed-up, with 23 (44.2%) in the discontinuous group and 29 (55.8%) in the continuous group. Compared with the continuous group, the discontinuous group received volumes closer to those prescribed, equal or higher calories, and more protein. The capillary glucose values were within the reference range in the discontinuous group, while the continuous group presented elevated values. Both groups presented hypoalbuminaemia, haemoglobin, and haematocrit below the reference values; however, in the discontinuous group, the serum albumin values improved during hospitalisation relative to the continuous. CONCLUSIONS: The method involving discontinuation of EN for 4h was more effective in meeting nutrient recommendations compared with the continuous method. Additionally, in the discontinuous group, we observed a better control of glycaemia when compared to that of the continuous group.

Introdução: A hiperglicemia pode estar presente em até 38% dos pacientes hospitalizados.O controle glicêmico está associado a melhores desfechos clínicos. Objetivo: avaliar o comportamento da variabilidade glicêmica em pacientes hospitalizados com Diabetes Mellitus 2. Metodologia: Estudo transversal, composto por pacientes hospi-talizados com e sem diabetes, adultos e idosos, de ambos os gêneros, em terapia nutricional enteral. As glicemias foram medidas por testes de glicemia capilar e classificadas como normoglicemia, hiperglicemia e variabilidade glicêmica, avaliados a partir do desvio-padrão glicêmico e coeficiente de variação glicêmico. Foram avaliados dados bioquímicos como Proteína C-reativa. A análise de variância de duas vias (ANOVA) foi utilizada para comparar os grupos, além da correlação de Spearman. Resultados: Participaram 85 indivíduos, com diabetes mellitus 2 (20%; n= 17), e sem diabetes mellitus (80%; n = 68), sendo 34% (n = 29) adultos e 66% (n=56) idosos. Adultos e idosos com diabetes mellitus apresentaram hiperglicemia em relação aos pacientes não diabéticos (p<0,01), valores supe-riores de desvio-padrão glicêmico (p<0,01) e coeficiente de variação glicêmica em relação aos pacientes sem dia-betes (p= 0,03), no entanto, não foram classificados com variabilidade glicêmica. Os valores da Proteína C-reativa foram correlacionados com o desvio-padrão glicêmico (R= 0,29; p= 0,0065), no entanto, a quantidade de carboi-dratos infundida na dieta enteral não se correlacionou estatisticamente com as glicemias nem com a variabilidade glicêmica dos pacientes (p>0,05). Conclusão: pacientes hospitalizados com ou sem diabetes mellitus 2 não apre-sentaram variabilidade glicêmica, demonstrando um controle glicêmico na hospitalização. (AU)

Introduction: Hyperglycemia may be present in up to 38% of hospitalized patients. Glycemic control is associated with better clinical outcomes. Objective: assess the behavior of glycemic variability in hospitalized patients with Diabetes Mellitus 2. Methodology: Cross-sectional study composed of hospitalized patients with and without diabetes, adults and elderly, of both genders, undergoing enteral nutritional therapy. Blood glucose was measured by capillary blood glucose tests and classified as normoglycemia, hyperglycemia, and glycemic variability, assessed from the glycemic standard deviation and glycemic variation coefficient. Biochemical data such as C-reactive protein were assessed. Two-way analysis of variance (ANOVA) was used to compare the groups, in addition to Spearman's correlation. Results: Eighty-five individuals with diabetes mellitus 2 (20%; n=17) and without diabetes mellitus (80%; n=68) participated in the study; 34% (n=29) were adults, and 66% (n=56) were elderly. Adults and elderly people with diabetes mellitus presented hyperglycemia concerning non-diabetic patients (p<0.01), higher values of glycemic standard deviation (p<0.01), and glycemic variation coefficient concerning patients without diabetes (p= 0.03); however, they were not classified with glycemic variability. The C-reactive protein values were correlated with the glycemic standard deviation (R= 0.29; p= 0.0065); however, the amount of carbohydrates infused in the enteral diet was not statistically correlated with glycemia or with the glycemic variability of patients (p>0.05). Conclusion: hospitalized patients with or without diabetes mellitus 2 did not show glycemic variability, demonstrating glycemic control during hospitalization. (AU)

Fatores associados com a presença de anemia em pacientes hospitalizados / Factors associated with the presence of anemia in hospitalized patients

Introdução: Anemia é definida pela diminuição da concentração de hemoglobina circulante no sangue, podendo ser desencadeada por mecanismos fisiopatológicos e deficiências alimentares. Objetivou-se avaliar fatores associados à presença e ao tipo de anemia em pacientes hospitalizados. Métodos: Estudo retrospectivo, quantitativo realizado em hospital municipal da região central do Rio Grande do Sul. Fizeram parte do estudo pacientes hospitalizados em diferentes clínicas, com idade superior a 18 anos. Os dados foram coletados de fichas preenchidas pelos acadêmicos do curso de Nutrição durante o estágio curricular. As fichas eram compostas pelos seguintes dados: diagnóstico médico, doenças associadas, dados antropométricos como Índice de Massa Corporal (IMC) e exames laboratoriais como o hemograma. Resultados: A amostra foi composta por 100 indivíduos hospitalizados, 39% adultos e 61% idosos; 76% dos pacientes apresentaram anemia, sendo 35,4% (n= 34) anemia leve, 29% (n=28) moderada e 11,6% (n=11) grave. Percebeu-se que os idosos estão mais anêmicos em relação aos adultos. Doenças hematológicas, infecciosas, gastroenterológicas e pneumológicas tiveram maiores associações com a presença de anemia nos pacientes. Parâmetros como volume corpuscular médio e amplitude de distribuição dos eritrócitos encontraram-se normais nos pacientes. Além disso, observou-se relação inversamente proporcional da gravidade de anemia com o estado nutricional dos pacientes. Conclusão: A maioria dos pacientes hospitalizados estava anêmica, principalmente idosos. Alterações observadas no eritrograma foram semelhantes às encontradas na anemia por doença crônica. O baixo IMC e doenças associadas com alterações na eritropoiese, perda sanguínea e estimulação do sistema imunológico tiveram maiores associações com a presença de anemia nesses pacientes.

Introduction: Anemia is defined as a decreased concentration of circulating blood hemoglobin, and it can be triggered by pathophysiological mechanisms and nutritional deficiencies. We aimed to evaluate factors associated with the presence and type of anemia in hospitalized patients. Methods: This is a retrospective, quantitative study performed in a municipal hospital in central Rio Grande do Sul. The study participants were patients hospitalized at different healthcare institutions and aged 18 years or older. Data were collected through forms filled out by undergraduate nutrition students at their academic internship period. The forms included the following data: medical diagnosis, associated diseases, anthropometric data such as body mass index (BMI), and laboratory examinations such as blood counts. Results: The sample comprised 100 hospitalized individuals, of which 39% were adults and 61% were older adults; 76% of the patients presented anemia, where 35.4% (n=34) had mild anemia, 29% (n=28) had moderate anemia, and 11.6% (n = 11) had severe anemia. We noticed that older adults were more severely anemic than adults. Blood disorders and infectious, gastrointestinal, and respiratory diseases were more strongly associated with the presence of anemia in these patients. Parameters such as mean corpuscular volume and red cell distribution width were normal. Moreover, we observed an inversely proportional relationship between anemia severity and the patients' nutritional status. Conclusion: Most hospitalized patients were anemic, especially the older adults. Alterations seen in the erythrogram were similar to those found in anemia of chronic disease. Low BMI and diseases linked to changes in erythropoiesis, blood loss, and stimulation of the immune system were more strongly associated with the presence of anemia in these patients.

Low Food Consumption Interferes with the Nutritional Status of Surgical Patients with Neoplasia of the Gastrointestinal Tract.

Nutritional support strongly influence the nutritional status of the surgical neoplastic patients. This study aimed to evaluate the influence of food consumption on the perioperative nutritional status of hospitalized patients with neoplasia of the upper (UGIT) and lower (LGIT) gastrointestinal tract. METHOD: Observational, longitudinal, and prospective study. Data collected: food consumption, Subjective Global Assessment, anthropometry, laboratory tests. RESULTS: Eighty patients were followed up: 43 (54%) in the UGIT and 37 (46%) in the LGIT. The consumption in the perioperative period was lower than the usual consumption in the UGIT and LGIT groups, respectively, of energy (14.2 ± 6.5; 22.8 ± 11.2 Kcal/kg/d, p < 0.001; 13.6 ± 1.2; 19.0 ± 2.0 Kcal/kg/d; p = 0.014), protein (1.1 ± 0.7; 0.6 ± 0.3 g/kg/d, p < 0.001; 0.8 ± 0.1; 0.5 ± 0.1 g/kg/d; p = 0.058), selenium, zinc and copper. Most patients presented in the UGIT and LGIT groups, respectively, worsening malnutrition and muscle depletion according to the Subjective Global Assessment (61.9%; 51.4%) and hypoalbuminemia, mainly in the UGIT in the postoperative. CONCLUSION: Low food consumption during the perioperative period associated with prolongation of the postoperative fasting period worsens the nutritional status of patients undergoing surgery of the gastrointestinal tract for neoplasia, especially in the UGIT group.

Increased postoperative fasting time aggravates the nutritional status in patients with gastrointestinal tract neoplasia

ABSTRACT Surgical patients with gastrointestinal cancer often suffer from malnutrition. This study aimed to evaluate the influence of fasting time on the nutritional status of patients hospitalized with preoperative and postoperative gastrointestinal tract neoplasms. Observational, longitudinal, and prospective study conducted in the surgical unit at a public-school hospital. The patients were divided into groups: upper (UGIT) and lower (LGIT) gastrointestinal tract. Follow-up started within 72 h of hospitalization with reassessment 72 h after surgery. Data collected: sex, age, type and duration of surgery, preoperative (compared with 8 h) and postoperative (compared with 24 h) fasting time, food acceptance, Subjective Global Assessment, anthropometry, and laboratory tests. Analyses: Student t, Wilcoxon, and chi-square tests. Fifty-one patients were followed up, 29 (57%) UGIT and 22 (43%) LGIT. The preoperative fasting time was 8.2±2.8 h in UGIT and 8.1±2.2 h in LGIT groups, respectively; however, postoperative fasting times in UGIT (60.4±40.7 h) and LGIT groups (57.6±38.2 h) were longer than 24 h (P<0.001). Although eutrophic in the preoperative period, in the postoperative most patients in the UGIT and LGIT groups presented, respectively, malnutrition (71%; 59%; P<0.001), severe weight loss (79%; 80%), a significant correlation between triceps skinfold and postoperative fasting time (r= -0.306; P= 0.03), and hemoglobin and albumin values (r= 0.633; P<0.001), additionally low dietary acceptance, especially in the UGIT group. Prolonging postoperative fasting time worsened the nutritional status of surgical patients, especially in the UGIT group.

RESUMEN Los pacientes quirúrgicos con cáncer gastrointestinal a menudo sufren desnutrición. El objetivo de este estudio fue evaluar la influencia del tiempo de ayuno en estado nutricional de pacientes hospitalizados con neoplasias del tracto gastrointestinal preoperatorio y posoperatorio. Estudio observacional, longitudinal y prospectivo realizado en unidad quirúrgica de un hospital escolar público. Los pacientes fueron divididos en grupos: tracto gastrointestinal superior (UGIT) y inferior (LGIT). El seguimiento se inició dentro del 72 h de la hospitalización con reevaluación 72 h después de la cirugía. Datos recolectados: sexo, edad, tipo y duración de la cirugía, tiempo de ayuno preoperatorio (comparado con 8 h) y postoperatorio (comparado con 24 h), aceptación de dieta, Evaluación Subjetiva Global, antropometría y pruebas de laboratorio. Análisis: pruebas de T, Wilcoxon y chi-cuadrado. Se siguió 51 pacientes, 29 (57%) en UGIT y 22 (43%) en LGIT. El tiempo de ayuno preoperatorio fue 8,2±2,8 h (UGIT) y 8,1±2,2 h (LGIT); sin embargo, los tiempos de ayuno posoperatorio en UGIT (60,4±40,7 h) y LGIT (57,6±38,2 h) fueron superiores a 24 h (P<0,001). Aunque eutróficos en preoperatorio, en postoperatorio la mayoría de los pacientes (UGIT y LGIT, respectivamente) presentaron desnutrición (71%; 59%; P<0,001), pérdida de peso severa (79%; 80%), correlación significativa entre pliegue cutáneo del tríceps y tiempo de ayuno posoperatorio (r= -0.306; P= 0.03), valores de hemoglobina y albúmina (r= 0,633; P<0,001), y baja aceptación de dieta, especialmente del UGIT. La prolongación del ayuno postoperatorio empeoró el estado nutricional de los pacientes quirúrgicos, especialmente del UGIT.

Relation of micronutrients with antioxidant properties in patients with chronic diseases and exclusive enteral nutrition

ABSTRACT Objective: To evaluate the intake of micronutrients with antioxidant properties through exclusive enteral nutrition therapy (ENT) in hospitalized patients with chronic diseases compared to the estimated average requirement (EAR). Methods: This prospective, longitudinal, descriptive, observational study was performed in a public hospital, with adult and elderly patients. The adequacy of the volume of ENT prescribed and offered was considered satisfactory when >80%. The adequacy of micronutrients with antioxidant properties was performed according to the estimated average need (EAR). Data were considered statistically significant when p<0.05. Results: Of the 53 included patients, 58.5% were male. Most of patients (45.3%) were in the neurology clinic, and the main cause was cerebral vascular accident (18.9%). The volume administered was less than the prescribed volume of ENT in both male and female patients. However, recommendations for micronutrients with antioxidant properties, such as vitamin A, vitamin C, vitamin E, zinc, selenium, copper and iron, are according to EAR and did not exceed the tolerable intake limit (upper limit, UL), (p<0.05). The present study shows a very large variability in the concentration of micronutrients in each enteral diet. It is necessary to consider the pathologies that affect the patient, as some health conditions may be able to require specific amounts of micronutrients. Conclusions: Patients received a lower volume of enteral nutrition therapy compared to the prescribed volume. The micronutrient concentrations were consistent with daily EAR recommendations and did not exceed the tolerable intake limit (UL) for healthy individuals.

RESUMEN Objetivo: Evaluar la ingesta de micronutrientes con propiedades antioxidantes a través de la terapia de nutrición enteral exclusiva (ENT) en pacientes hospitalizados con enfermedades crónicas en comparación con el requerimiento promedio estimado (RPE). Métodos: Prospectivo, longitudinal, descriptivo y de observación, se realizó en un hospital público con pacientes adultos y ancianos. La adecuación del volumen de ENT prescrito y ofrecido se consideró satisfactoria cuando fue >80%. La adecuación de micronutrientes con propiedades antioxidantes se realizó de acuerdo con la RPE. Se consideraron estadísticamente significativos p<0,05. Resultados: De los 53 pacientes incluidos, 58,5% eran hombres. La mayoría de los pacientes (45,3%) se encontraban en la consulta de neurología y la principal causa fue el accidente vascular cerebral (18,9%). El volumen administrado fue menor que el volumen prescrito de ENT tanto en pacientes masculinos como femeninos. Sin embargo, las recomendaciones de micronutrientes con propiedades antioxidantes, como vitamina A, vitamina C, vitamina E, zinc, selenio, cobre y hierro, están de acuerdo con la RPE y no superan el límite de ingesta tolerable (UL), (p<0,05). El presente estudio muestra una variabilidad muy grande en la concentración de micronutrientes en cada dieta enteral. Es necesario considerar las patologías que afectan al paciente, ya que algunas condiciones de salud pueden requerir cantidades específicas de micronutrientes. Conclusiones: Los pacientes recibieron un volumen menor de ENT en comparación con el volumen prescrito. Las concentraciones de micronutrientes fueron consistentes con las recomendaciones diarias de la RPE y no excedieron el límite de ingesta tolerable (UL) para individuos sanos.

Dysphagia, Immobility, and Diet Acceptance: Main Factors Associated with Increased Risk of Pressure Injury in Patients Hospitalized after Stroke.

OBJECTIVE: To determine the predisposing factors for PI in patients hospitalized after stroke. METHODS: This 7-day longitudinal study followed up with patients hospitalized after stroke. Assessments included mobility, nutrition, and the presence of dysphagia and anemia. The nutrition evaluation was based on anthropometric, biochemical, and dietary determinants. Pressure injury (PI) risk was assessed via the Braden Scale. Mann-Whitney and Kruskal-Wallis tests were applied. RESULTS: Patients who were bedridden showed a greater risk of PI development upon admission (P = .004) and 7 days later (P < .001) compared with patients who could ambulate. Patients who were not dysphagic presented a lower risk of PI development in relation to patients who were dysphagic on admission (P = .047) and 7 days later (P < .001). On admission, patients with good and average diet acceptance had a lower PI risk (P = .002; P = .034) compared with those with a low acceptance. Body mass index was lower in patients at a high risk of developing PI compared with those at moderate risk (P = .02). Hemoglobin and hematocrit were statistically lower among patients who were at high risk of PI compared with patients who were low risk. CONCLUSIONS: Predisposing factors such as immobility, dysphagia, low diet acceptance, nutrition risk, and anemia are associated with a greater risk of PI development.

Biochemical and nutritional profile of patients with exclusive enteral nutrition during hospitalization / Perfil bioquímico y nutricional de pacientes con nutrición enteral exclusiva durante hospitalización

BACKGROUND: Enteral nutrition therapy (ENT) is intended to restore the nutritional status of patients. OBJECTIVE: The objective of this study was to evaluate the biochemical and nutritional profile of hospitalized patients with exclusive enteral nutrition. METHODS: It is a longitudinal study, with a sample of 42 hospitalized young and elder adults, with exclusive ENT, for at least seven days. The patients were submitted to nutritional, anthropometric (Body Mass Index, corrected arm muscle area and arm muscle circumference) and biochemical evaluation as albumin, hemoglobin, C-reactive protein, vitamin C, Iron, Zinc and Copper serum. Results and DISCUSSION: It was observed that anthropometric parameters such as weight, BMI, muscle area and circumference increased during hospitalization time only in the elderly (P= 0.016; P=0.018; P = 0.021; P = 0.020). The percentage of adequacy in energy, protein and micronutrients with vitamin C, iron, zinc and copper were adequate during hospitalization for both age groups, according to the estimated average needs. Serum levels of these micronutrients were within normal values for both age groups, with the exception of zinc, which decreased during hospitalization in the elderly. This may be associated with the greater need for this mineral in this age group or with a implicate in its absorption. CONCLUSION: The ENT influence the weight and muscle mass gain in hospitalized elderly patients and, although the appropriate administration of micronutrients, the absorption of zinc was affected. Therefore, monitoring of enteral nutrition is essential in order to avoid worsening nutritional status during hospitalization

INTRODUCCIÓN: La terapia de nutrición enteral (TNE) tiene la finalidad de recuperar el estado nutricional de los pacientes. Objectivo: Se evaluó el perfil bioquímico y nutricional de pacientes hospitalizados con nutrición enteral exclusiva. MÉTODOS: Estudio longitudinal, con muestra compuesta por 42 adultos y ancianos hospitalizados, con TNE exclusiva, por lo menos siete días. Los pacientes fueron sometidos a evaluación nutricional, antropométrica (Índice de Masa Corporal, área muscular del brazo corregida y circunferencia del brazo) y bioquímica como albúmina, proteína C-reactiva, vitamina C, hierro zinc y cobre sérico. Resultados y DISCUSIÓN: Se observó que los parámetros antropométricos como el peso, IMC, área y circunferencia muscular del brazo aumentaron durante el tiempo de internación solo en los ancianos (P= 0.016; P=0.018; P = 0.021; P = 0.020). El porcentaje de adecuación de energía, proteica y micronutrientes como vitamina C, hierro, zinc y cobre fueron adecuados durante el tiempo de internación para ambos grupos de edad, de acuerdo con las necesidades medias estimadas. Los niveles séricos de estos micronutrientes se mantuvieron dentro de los valores normales para ambos grupos de edad, a excepción del zinc, que disminuyó durante la hospitalización en ancianos. Esto puede asociarse a la mayor necesidad de este mineral en este grupo de edad o a un deterioro en su absorción. CONCLUSIÓN: La TNE influye en el aumento de peso y la masa muscular en ancianos y, apesar de la administración adecuada de micronutrientes, se observó un deterioro en la absorción de zinc. Por lo tanto, el monitoreo de la nutrición enteral es esencial para evitar el empeoramiento del estado nutricional durante la hospitalización

Association of anemia and malnutrition in hospitalized patients with exclusive enteral nutrition.

INTRODUCTION: enteral nutrition therapy maintains and/or regains the nutritional status of the common patient in hospital settings, where anemia and malnutrition are food related and are very common diseases. OBJECTIVE: to determine and associate the presence of anemia and malnutrition in hospitalized patients with exclusive enteral nutrition. METHODS: a prospective, cross-sectional study with patients receiving exclusive enteral nutrition up to 72 hours after hospitalization. A nutritional evaluation was performed, consisting of anthropometric data, such as weight, circumferences, and skinfolds; dietary evaluation (data were collected through an electronic medical record) and biochemistry data (hemogram, albumin, C-reactive protein, capillary glucose monitoring). RESULTS: the population consists of 77 individuals. As the patients presented greater severity of anemia, corrected arm muscle area, calf circumference and serum albumin levels were reduced while C-reactive protein increased significantly (p < 0.05). In relation to the low weight classification according to the body mass index (BMI), it was observed that the anthropometric parameters such as corrected arm muscle area (R = 0.74, p < 0.001), adductor pollicis muscle thickness (R = 0.23, p = 0.046) and calf circumference (R = 0.81, p < 0.001) decreased as did biochemical parameters albumin (R = 0.26; p = 0.048) and capillary blood glucose (R = 0.34, p = 0.018). CONCLUSION: anemia has an important relation with anthropometric markers that evaluate the depletion of lean mass; the BMI has a strong association with all the anthropometric parameters evaluated, as well as the albumin and capillary blood glucose, except with the values of hemoglobin.

Introducción: la terapia de nutrición enteral mantiene y/o recupera el estado nutricional del paciente en cuidados hospitalarios, donde la anemia y la desnutrición están relacionadas con los alimentos y son enfermedades muy comunes. Objetivo: determinar y asociar la presencia de anemia y malnutrición en pacientes hospitalizados con nutrición enteral exclusiva. Métodos: estudio transversal prospectivo con pacientes que recibieron nutrición enteral exclusiva hasta 72 horas tras la hospitalización. Se realizó una evaluación nutricional por medio de datos antropométricos tales como peso, circunferencias y pliegues cutáneos, evaluación dietética (datos recogidos a través de un expediente médico electrónico) y datos bioquímicos (hemograma, albúmina, proteína C reactiva, monitorización capilar de glucosa). Resultados: la muestra está compuesta de 77 personas. En los pacientes que presentaban una anemia de mayor gravedad, el área del músculo del brazo corregida, la circunferencia de la pantorrilla y los niveles de albúmina sérica se redujeron, mientras que la proteína C-reactiva aumentó significativamente (p < 0,05). Con relación a la clasificación de bajo peso según el IMC, se observó que los parámetros antropométricos, como el área del músculo del brazo corregida (R = 0,74, p < 0,001), el espesor del músculo aductor del pulgar (R = 0,23, p = 0,046) y la circunferencia de la pantorrilla (R = 0,81, p < 0,001) disminuyeron, al igual que los parámetros bioquímicos de albúmina (R = 0,26, p = 0,048) y glucosa en sangre capilar (R = 0,34, p = 0,018). Conclusión: la anemia tiene una relación importante con marcadores antropométricos que evalúan el agotamiento de la masa magra; el IMC tiene una fuerte asociación con todos los parámetros antropométricos evaluados, así como con la albúmina y la glucosa en sangre capilar, excepto con los valores de hemoglobina

Perfil nutricional de idosos hospitalizados com anemia / Nutritional profile of elderly patients hospitalized with anemia

Introdução: O envelhecimento é um processo natural de todo o ser humano, que acaba desencadeando modificações funcionais e anatômicas no corpo como a diminuição da palatabilidade. Desse modo, o objetivo deste estudo foi identificar o perfil nutricional de idosos hospitalizados com anemia. Métodos: O estudo do tipo transversal, desenvolvido com idosos de ambos os sexos com idade igual ou superior a 60 anos internados em um hospital do município de Santa Maria/RS. Foram coletados dos prontuários: motivo de internação, diagnóstico e doenças associadas e dados antropométricos: peso, altura, IMC, circunferência do braço, dobra cutânea tricipital e espessura do músculo adutor do polegar, além de dados bioquímicos como o hemograma. Resultados: Em relação aos dados antropométricos, não se observou diferença estatisticamente significativa no peso atual, dobra cutânea tricipital e espessura do músculo adutor do polegar, apesar de esses parâmetros estarem mais altos em idosos sem anemia, em comparação aos idosos com anemia. No entanto, a circunferência do braço foi significativamente maior em pacientes sem anemia, em relação aos sem anemia. Os valores de hematócrito, hemoglobina, volume corpuscular médio e hemoglobina corpuscular média foram estatisticamente menores em idosos com anemia. Verificou-se correlação positiva significativa do peso com a hemoglobina dos idosos hospitalizados e da circunferência do braço com a hemoglobina desses idosos. Conclusões: Conclui-se que os parâmetros antropométricos possuem uma importante associação com o hemograma e, desta forma, a avaliação nutricional completa pode contribuir para realizar um diagnóstico e tratamento mais precoce, a fim de diminuir o tempo de internação desses pacientes (AU)

Introduction: Aging is a natural process of every human being, one which eventually triggers a number of functional and anatomical changes in the body such as reduction of palatability. The aim of this study was to identify the nutritional profile of hospitalized elderly patients with anemia. Methods: The cross-sectional study was carried out with elderly patients of both sexes aged 60 years or over admitted to a hospital in the city of Santa Maria, RS. The following data were collected from the medical records: reason for hospitalization, diagnosis and associated diseases, and anthropometric data (weight, height, BMI, arm circumference, triceps skinfold thickness, and thumb adductor muscle thickness) as well as biochemical data such as complete blood count. Results: No statistically significant difference was found for current weight, triceps skinfold thickness and thumb adductor muscle thickness, although these parameters were higher in the elderly without anemia than in the elderly with anemia. However, arm circumference was significantly higher in patients without anemia, compared to those without anemia. The values of hematocrit, hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin were statistically lower in the elderly patients with anemia. There was a significant positive correlation of weight with hemoglobin and of arm circumference with hemoglobin in these hospitalized elderly. Conclusions: It is concluded that the anthropometric parameters have an important association with total blood count, so a complete nutritional evaluation can contribute to earlier diagnosis and treatment, in order to reduce the hospitalization time of these patients (AU)

Risco nutricional em pacientes hospitalizados durante o período de internação / Nutritional risk in hospitalized patients during hospital stay

Introdução: A desnutrição e a perda de massa muscular em pacientes hospitalizados interferem no progresso dos pacientes, pois, aumentam o tempo de internação, os riscos de morbimortalidade, causando grande impacto na qualidade de vida destes indivíduos. Objetivos: Analisar o risco nutricional em pacientes hospitalizados durante o período de internação. Métodos: Foram analisadas as fichas de indivíduos internados em diferentes clínicas, sendo estes divididos em três grupos o grupo 1 teve um tempo de internação entre sete a 14 dias com média de idade de 49,2 ± 12,7 anos; grupo 2 com tempo de internação de 15 a 29 dias com média de idade de 51,8 ± 16 anos; grupo 3 com tempo de internação ≥ 30 dias com idade média de 50 ± 15 anos. Resultados: Fizeram parte do estudo adultos e idosos de ambos os sexos, onde o grupo 1 apresentou uma amostra de 41% (n=49); o grupo 2 com 35% (n=41) e; o grupo 3 com 23% (n=27). Foi identificado que pacientes com tempo de internação > 15 dias perderam de peso, reduziram IMC (kg/m²) e aumentaram seu percentual de perda de peso. Porém o IMC (kg/m²) tanto do momento da internação quanto o mais próximo da alta se mantiveram sempre adequados nos diferentes tempos de internação em adultos e idosos. Foi evidenciada também uma correlação entre dados bioquímicos e o peso. Discussão: Os pacientes não se encontravam desnutridos no momento da internação, um fator positivo provavelmente favorecido pelo estado nutricional encontrado no momento da internação, e também pelo acompanhamento nutricional deste indivíduo durante o período que esteve internado. Conclusão: A análise em conjunto dos dados encontrados no presente trabalho permite sugerir que os pacientes com um período de internação > 15 dias apresentaram maior risco nutricional, pois, perderam mais peso e consequentemente ocorreu alteração do IMC (kg/m²), percentual de perda de peso e de parâmetros bioquímicos, embora não o suficiente para serem considerados desnutridos

Introduction: Malnutrition and muscle mass loss affect the progress of hospitalized patients because they increase hospitalization time, morbidity and mortality risks, and cause major impact on the quality of life of these individuals. Aim: Analyzing the nutritional risk in hospitalized patients during hospitalization. Methods: medical records of individuals hospitalized in different clinics were analyzed. The patients were divided in three groups, namely: group 1 - patients at mean age 49.2 ± 12.7 years hospitalized between 7-14 days; group 2 - patients at mean age 51.8 ± 16 years hospitalized between 15-29 days; group 3 - patients at mean age 50 ± 15 years hospitalized for more than 30 days. Results: Adults and seniors from both genders participated in the study; group 1 comprised 49 patients (41%); group 2, 41 patients (35%) and; group 3, 27 patients (23%). Patients hospitalized for more than 15 days showed weight loss, reduced BMI (kg/m²) and higher weight loss percentage. However, the BMI (kg/m²) of both the adult and the elderly patients at the time of hospital admission and close to discharge remained appropriate. There was also correlation between the biochemical data and weight. Discussion: Patients were not undernourished at the time they were hospitalized. It is a positive factor, which was probably favored by their nutritional status at the time of hospitalization as well as by the nutritional monitoring of these individuals during the period they remained hospitalized. Conclusion: The joint analysis of the data found in the current study allows suggesting that the patients hospitalized for more than 15 days showed greater nutritional risk because they lost more weight. Consequently, they underwent changes in the BMI (kg/m²), in the weight loss percentage and in the biochemical parameters. However, these changes were not significant enough for the patients to be considered malnourished

EFFECT OF ANTIOXIDANT POTENTIAL ON SEVERITY OF CIRRHOSIS IN HUMANS.

BACKGROUND/AIMS: to examine the relationship between the antioxidant potential and severity parameters of cirrhosis in humans. METHODS: fifteen patients with hepatic cirrhosis (nine subjects - Child group B, and six subjects - Child group C) and nine control subjects were enrolled in the study. The main criteria taken into account to characterize the diagnosis of cirrhosis and its complications were the AST: ALT ratio, AST to platelet ratio index, Bonacini score, Meld score and Child classification. Those parameters were determined based on laboratory results and patient's clinical records. Se, Zn, ascorbic acid (AA) levels and oxidative stress parameters were measured in blood samples of cirrhotic patients. RESULTS: the analysis of plasma levels of Se and AA showed low concentrations in cirrhotic patients compared with control subjects (P < 0.05). Though, there was a positive correlation between plasma of Se and severity parameters of cirrhosis in patients of Child group B and C. In the activity of the antioxidant enzymes only catalase was lower in patients of Child group C compared with control group. CONCLUSION: we found low plasma levels of Se and AA among cirrhotic patients. However, is not clear why selenium levels tend to increase with the severity of liver cirrhosis.

Introducción/Objetivos: examinar la relación entre los potenciales antioxidantes y los parámetros de gravedad de la cirrosis en los seres humanos. Métodos: quince pacientes con cirrosis hepática (nueve sujetos - grupo Child B, y seis sujetos - grupo Child C) y nueve sujetos control fueron incluidos en el estudio. Los principales criterios que se tuvieron en cuenta para caracterizar el diagnóstico de la cirrosis y sus complicaciones fueron la AST: relación de ALT, AST índice de la relación de plaquetas, clasificación Bonacini, clasificación MELD y clasificación de Child. Estos parámetros fueron determinados con base en los resultados de laboratorio y los registros clínicos del paciente. Se midieron los niveles de Zn, ácido ascórbico (AA) y los parámetros de estrés oxidativo en muestras de sangre de pacientes cirróticos. Resultados: el análisis de los niveles plasmáticos de Se y AA mostraron bajas concentraciones en los pacientes cirróticos en comparación con los sujetos control (P < 0,05); sin embargo, hubo una correlación positiva entre el plasma de Se y los parámetros de gravedad de la cirrosis en pacientes del grupo Child B y C. En la actividad de las enzimas antioxidantes catalasa solamente fue menor en los pacientes del grupo Child C, en comparación con el grupo control. Conclusión: se encontraron niveles bajos en plasma de Se y AA en pacientes cirróticos. Sin embargo, no está claro por qué los niveles de selenio tienden a aumentar con la gravedad de la cirrosis hepática.

Effect of Uncaria tomentosa Extract on Apoptosis Triggered by Oxaliplatin Exposure on HT29 Cells.

Background/Aim. The use of herbal products as a supplement to minimize the effects of chemotherapy for cancer treatment requires further attention with respect to the activity and toxicity of chemotherapy. Uncaria tomentosa extract, which contains oxindole alkaloids, is one of these herbal products. The objective of this study was to evaluate whether Uncaria tomentosa extract modulates apoptosis induced by chemotherapy exposure. Materials and Methods. Colorectal adenocarcinoma cells (HT29 cells) were grown in the presence of oxaliplatin and/or Uncaria tomentosa extract. Results. The hydroalcoholic extract of Uncaria tomentosa enhanced chemotherapy-induced apoptosis, with an increase in the percentage of Annexin positive cells, an increase in caspase activities, and an increase of DNA fragments in culture of the neoplastic cells. Moreover, antioxidant activity may be related to apoptosis. Conclusion. Uncaria tomentosa extract has a role for cancer patients as a complementary therapy. Further studies evaluating these beneficial effects with other chemotherapy drugs are recommended.

Nutritional care in peptic ulcer / Cuidados nutricionais na úlcera péptica

INTRODUCTION: Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease. AIM: To update nutritional therapy in adults' peptic ulcer. METHODS: Exploratory review without restrictions with primary sources indexed in Scielo, PubMed, Medline, ISI, and Scopus databases. RESULTS: Dietotherapy, as well as caloric distribution, should be adjusted to the patient's needs aiming to normalize the nutritional status and promote healing. Recommended nutrients can be different in the acute phase and in the recovery phase, and there is a greater need of protein and some micronutrients, such as vitamin A, zinc, selenium, and vitamin C in the recovery phase. In addition, some studies have shown that vitamin C has a beneficial effect in eradication of H. pylori. Fibers and probiotics also play a important role in the treatment of peptic ulcer, because they reduce the side effects of antibiotics and help reduce treatment time. CONCLUSION: A balanced diet is vital in the treatment of peptic ulcer, once food can prevent, treat or even alleviate the symptoms involving this pathology. However, there are few papers that innovate dietotherapy; so additional studies addressing more specifically the dietotherapy for treatment of peptic ulcer are necessary. .

INTRODUÇÃO: A úlcera péptica é uma lesão que ocorre na mucosa do trato gastrointestinal, sendo caracterizada por um desequilíbrio entre fatores agressores e protetores da mucosa gástrica, tendo como principal fator etiológico o H. pylori. A dietoterapia é fundamental na prevenção e tratamento dessa patologia. OBJETIVO: Rever a terapia nutricional na úlcera péptica em adultos. MÉTODOS: A metodologia utilizada foi um estudo exploratório de revisão do conhecimento disponível na literatura científica. RESULTADOS: A dietoterapia bem como a distribuição calórica deve ser ajustada as necessidades do paciente com objetivo de normalizar o estado nutricional e promover a cicatrização. As recomendações de nutrientes podem ser diferenciadas nas fases aguda e de recuperação, havendo uma maior necessidade proteica e de alguns micronutrientes como vitamina A, zinco, selênio e vitamina C na fase de recuperação. Além disso, alguns estudos evidenciam que a vitamina C tem efeito benéfico na erradicação do H. pylori. As fibras e probióticos também possuem um importante papel no tratamento da úlcera péptica, reduzindo os efeitos colaterais dos antibióticos e auxiliando na redução do tempo de tratamento. CONCLUSÃO: Percebe-se que poucos são os trabalhos que evidenciam a terapia nutricional da úlcera e não há consenso sobre o tema. Com isso, mais estudos são necessários para abordar com maior especificidade o tratamento dietoterápico da úlcera péptica. Dieta equilibrada é fundamental no tratamento da úlcera péptica, uma vez que o alimento pode prevenir, tratar ou mesmo aliviar os sintomas que envolvem esta doença. No entanto, existem poucos trabalhos que inovam dietoterapia; assim, são necessários estudos adicionais abordando mais especificamente a dietoterapia para o tratamento de úlcera péptica. .

Consumo de alimentos com propriedades antioxidantes por idosos institucionalizados / Consumption of food with antioxidant properties institutionalized elderly

Objetivos: Analisar o consumo de micronutrientes com propriedades antioxidantes em idosos institucionalizados.Métodos: Realizou-se um estudo transversal com residentes de uma instituição de longa permanência para idosos do sexo masculino. O consumo alimentar foi avaliado por meio de observação direta das refeições realizadas e foi calculado no software dietWin Profissional 2008.A adequação dos macronutrientes seguiu as recomendações da Sociedade Brasileira de Alimentação e Nutrição e o consumo de micronutrientes foi analisado de acordo com a Ingestão Dietética de Referência. Os testes utilizados foram correlação de Sperman e descritiva simples. O nível de significância utilizado foi p<0,05.Resultados: O estudo incluiu 28 idosos do sexo masculino. A ingestão média de carboidratos e lipídios era adequada, porém o consumo médiode proteínas foi um pouco elevado. A ingestão média dos micronutrientes era inadequada, com exceção do consumo médio de zinco e ferro. O micronutriente com maior percentual de inadequação foi o tocoferol. Houve correlação positiva entre consumo de Tocoferol e lipídios e correlações negativas entre o consumo médio de vitamina C e a idade, entre o consumo médio de selênio e os níveis sanguíneos de leucócitos e entre triglicerídeos e consumo de zinco.Conclusões: Encontrou-se inadequação no consumo da maioria dos micronutrientes com propriedades antioxidantes. É importante estabelecerestratégias de educação nutricional e adequação do cardápio dos idosos institucionalizados para corrigir essas deficiências.

Aims: To analyze the consumption of micronutrients with antioxidant properties in institutionalized elderly.Methods: We conducted a cross-sectional study with residents of an institution for the aged male. Dietary intake was assessed by directobservation of meals and was calculated in DietWin Profisional 2008 software. Adequacy of macronutrients followed the recommendationsof the Brazilian Society of Food and Nutrition and micronutrient intake was analyzed according to the Dietary Reference Intakes. The tests used were Spearman correlation and descriptive statistics. The level of significance was p<0.05.Results: The study included 28 elderly males. The average intake of carbohydrates and lipids was adequate but the average protein intake was slightly elevated. The average intake of micronutrients was inadequate, except for the average intake of zinc and iron. Tocopherol was the micronutrient with the highest percentage of inadequacy. There was a positive correlation between consumption of tocopherol and lipids and negative correlations between the average intake of vitamin C and age, between the average selenium intake and blood levels of leukocytes and between triglycerides and zinc intake.Conclusions: The intake of most micronutrients with antioxidant properties was inadequate. It is important to establish strategies for nutrition education and adjustment of the menu of institutionalized elderly to correct these deficits.
