A Brazilian regional basic diet-induced chronic malnutrition drives liver inflammation with higher ApoA-I activity in C57BL6J mice

Malnutrition is still considered endemic in many developing countries. Malnutrition-enteric infections may cause lasting deleterious effects on lipid metabolism, especially in children living in poor settings. The regional basic diet (RBD), produced to mimic the Brazilian northeastern dietary characteristics (rich in carbohydrate and low in protein) has been used in experimental malnutrition models, but few studies have explored the effect of chronic RBD on liver function, a central organ involved in cholesterol metabolism. This study aimed to investigate whether RBD leads to liver inflammatory changes and altered reverse cholesterol metabolism in C57BL6/J mice compared to the control group, receiving a standard chow diet. To evaluate liver inflammation, ionized calcium-binding adapter protein-1 (IBA-1) positive cell counting, interleukin (IL)-1β immunohistochemistry, and tumor necrosis factor (TNF)-α and IL-10 transcription levels were analyzed. In addition, we assessed reverse cholesterol transport by measuring liver apolipoprotein (Apo)E, ApoA-I, and lecithin-cholesterol acyltransferase (LCAT) by RT-PCR. Furthermore, serum alanine aminotransferase (ALT) was measured to assess liver function. RBD markedly impaired body weight gain compared with the control group (P<0.05). Higher hepatic TNF-α (P<0.0001) and IL-10 (P=0.001) mRNA levels were found in RBD-challenged mice, although without detectable non-alcoholic fatty liver disease. Marked IBA-1 immunolabeling and increased number of positive-IBA-1 cells were found in the undernourished group. No statistical difference in serum ALT was found. There was also a significant increase in ApoA mRNA expression in the undernourished group, but not ApoE and LCAT, compared with the control. Altogether our findings suggested that chronic RBD-induced malnutrition leads to liver inflammation with increased ApoA-I activity.

Vitamin d deficiency and paratohommonium increase in late postoperative gastric bypass in roux-en-y / Deficiência de vitamina d e elevação do paratohôrmonio no pós-operatório tardio de bypass gástrico em y-de- roux

ABSTRACT Background : Roux-en-Y gastric bypass patients can experience changes in calcium metabolism and hyperparathyroidism secondary to vitamin D deficiency. Aim : To evaluate nutritional deficiencies related to the calcium metabolism of patients undergoing gastric bypass with a 10-year follow-up. Method : This is a longitudinal retrospective study of patients submitted to Roux-en-Y gastric bypass at a multidisciplinary clinic located in the Brazilian southeast region. The study investigated the results of the following biochemical tests: serum calcium, ionized calcium, vitamin D, and parathormone (PTH). The generalized estimating equations (GEE) determined the nutritional deficiencies using a significance level of 5%. Results : Among the patients who finished the study (120 months), 82.86% (n=29) had vitamin D deficiency, and 41.94% (n=13) had high PTH. Postoperative time had a significant effect on PTH (p=0.0059). The percentages of patients with vitamin D, serum calcium, and ionized calcium deficiencies did not change significantly over time. Conclusion : One of the outcomes was vitamin D deficiency associated with secondary hyperparathyroidism. These findings reaffirm the importance of monitoring the bone metabolism of patients submitted to Roux-en-Y gastric bypass. HEADINGS: Calcium deficiency. Vitamin D deficiency. Secondary hyperparathyroidism.

Resumo Racional: Pacientes submetidos ao bypass gástrico em Y-de-Roux, podem apresentar alterações do metabolismo do cálcio e hiperparatireoidismo secundário à deficiência de vitamina D. Objetivo: Avaliar as deficiências nutricionais relacionadas ao metabolismo do cálcio de pacientes submetidos à bypass gástrico em Y-de-Roux, com seguimento de 10 anos. Método: Um estudo retrospectivo longitudinal foi conduzido com pacientes submetidos à bypass gástrico em Y-de-Roux, em uma Clínica Multidisciplinar no Sudeste do Brasil. Investigou-se a frequência do acompanhamento médico e nutricional e os exames bioquímicos de cálcio sérico, cálcio iônico, vitamina D e paratormônio (PTH). Para a análise das deficiências nutricionais, foram utilizadas as Equações de Estimativas Generalizadas (EEG), com nível de significância de 5%. Resultados: Dos pacientes que permaneceram no estudo até o final (120 meses), 82,86% (29), apresentaram níveis de deficiência de vitamina D e 41,94% (13) apresentaram PTH elevado. O efeito do tempo foi significativo para o PTH (p=0,0059). Para a vitamina D, cálcio sérico e cálcio iônico, o percentual de deficiência manteve-se constante ao longo do tempo, sem diferença significativa entre os tempos. Conclusão: A deficiência de vitamina D, associada ao hiperparatireoidismo secundário, foi um desfecho encontrado. Tais achados reafirmam a importância do cuidado com o metabolismo ósseo, em pacientes submetidos à bypass gástrico em Y-de-Roux.

¿Puede usarse el receptor soluble de transferrina para diagnosticar anemia ferropénica y evaluar la respuesta al hierro en lactantes con desnutrición aguda moderada? / Can soluble transferrin receptor be used in diagnosing iron deficiency anemia and assessing iron response in infants with moderate acute malnutrition?

Objetivo. Evaluar la eficacia del receptor soluble de transferrina (RST) en el diagnóstico de la anemia ferropénica (AF) y en la evaluación de la respuesta al hierro en los lactantes con desnutrición aguda moderada (DAM). Población y métodos. Se reclutó a lactantes con valores de hemoglobina (Hb) inferiores a los valores umbrales de anemia para su edad y con anemia hipocrómica/microcítica observada en el frotis de sangre periférica. La DAM se definió como un puntaje Z de peso/estatura de entre < -2 y -3. Se compararon los valores del hemograma, los parámetros férricos y el RST entre 41 lactantes con DAM y anemia (grupo DA), 32 lactantes con anemia sin DAM (grupo A) y controles saludables (n= 30). Una vez completado el tratamiento de la anemia y la desnutrición, se repitieron las evaluaciones. Resultados. Además de los índices hematológicos compatibles con AF, los valores de hierro sérico (Fe) y saturación de transferrina (ST) eran significativamente menores, mientras que el valor de transferrina era significativamente mayor en los grupos DA y A en comparación con los controles (p < 0,001). Los valores de ferritina y proteína C-reactiva (PCR) eran significativamente más elevados en el grupo DA (p < 0,05 para la ferritina, p < 0,01 para la PCR). El valor medio del RST fue similar en ambos grupos (DA y A) (p > 0,05) y significativamente mayor que en los controles (p < 0,001). Después del tratamiento con hierro, el RST disminuyó en los grupos DA y A (p < 0,001) a valores similares a los observados en los controles. El RST se correlacionó negativamente con la Hb durante todo el estudio (grupo DA: r= -0,350, p < 0,05; grupo A: r= -0,683, p < 0,01). Conclusiones. Dado que los valores del RST en los grupos DA y A disminuyeron después del tratamiento con hierro, consideramos que este parámetro no estuvo afectado por la DAM ni la inflamación y puede usarse, por sí solo, para detectar la AF y supervisar la respuesta al tratamiento en los lactantes con DAM.

Objective. To evaluate the efficacy of soluble transferrin receptor (sTfR) in diagnosing iron deficiency anemia (IDA) and evaluating iron response in infants with moderate acute malnutrition (MAM). Population and methods. Infants withhemoglobin (Hb) levels lower than threshold values for anemia for their ages and hypochromic/ microcytic anemia on peripheral smear were recruited. MAM was defined as weight/height z score < -2 to -3. Complete blood count (CBC), iron parameters and sTfR were compared among 41 infants with MAM and anemia (MA group), 32 infants with anemia without MAM (group A), and healthy controls (n= 30). Following anemia and malnutrition treatment, tests were repeated. Results. Besides hematological indices compatible with IDA, serum iron (Fe) and transferrin saturation (TS) were significantly lower, while transferrin was significantly higher in MA and A groups compared to controls (p <0.001). Ferritin and C-reactive protein (CRP) were significantly higher in MA group (p <0.05 ferritin, p <0.01 for CRP). Mean sTfR was similar in both MA and A groups (p >0.05) and significantly higher than controls (p <0.001). Following iron treatment, sTfR decreased inboth MA and A groups (p <0.001) to similar values as controls. sTfR was negatively correlated to Hb throughout the study (for MA group, r= -0.350, p <0.05; for A group, r= -0.683, p <0.01). Conclusions. As sTfR values in both MA and A groups decreased following iron treatment, we believe that this parameter was not influenced by MAM or inflammation; and it alone can be used to detect IDA and monitor treatment response in infants with MAM.

Trace elements in plasma and nutritional assessment in patients with compensated cirrhosis on a liver transplant list

ABSTRACT Background - In chronic liver disease, trace element levels in plasma are usually low. However, the specific cause and functional implications of this abnormality are yet not well understood. These element levels may decrease as a result of abnormal liver function in patients with cirrhosis and/or malnutrition. Objective - To evaluate the nutritional status and the profile of trace elements in plasma of patients with cirrhosis on a liver transplant list and to correlate them with disease severity. Methods - This cross-sectional study evaluated 31 male patients diagnosed with compensated liver cirrhosis on a waiting list for liver transplant. Nutritional status was objectively evaluated through anthropometry using Mendenhall score and Blackburn classification, subjectively through the Detsky questionnaire and severity of the disease by MELD and CTP score. Trace elements (Zn, Se, Cu, Ca, Fe, Mg and Mn) in plasma were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Statistical analysis was performed using Mann-Whitney test. Results - According to the nutritional assessment 19 (61.3%) were malnourished and 12 (38.7%) were overweight. Regarding disease severity 12 (39%) were classified as Child A, 17 (55%), Child B and 2 (6%) Child C, with 46.9% of patients with MELD score >17. The trace element analysis indicated that 31 (100%) had Mn levels above the reference range, 23 (74.2%) low levels of Cu, 29 (93.5%) with deficiency of Se, and 31 (100%) low levels of Ca and Mg. Disease severity did not show statistical difference between the studied trace elements, in contrast to the nutritional status, in which the malnourished group showed higher levels of Mn (P=0.01) and Fe (P=0.01) and low levels of Zn (P=0.03) when compared to the overweight group. Conclusion - The results showed that the trace elements in plasma are altered in chronic liver disease; without significant correlation to disease severity, but correlated to nutritional status. Malnutrition is present in the patients studied, nonetheless a new scenario with an increase in the prevalence of overweight was verified regardless of the degree of hepatic decompensation.

RESUMO Contexto - Na doença hepática crônica os níveis plasmáticos de oligoelementos normalmente apresentam-se baixos, mas a causa específica e implicações funcionais desta anormalidade ainda não estão bem esclarecidas. Estes elementos podem estar diminuídos em consequência da função hepática alterada em pacientes com cirrose e/ou desnutrição. Objetivo - Avaliar o estado nutricional e o perfil de oligoelementos plasmáticos dos pacientes com cirrose hepática em lista para transplante e correlacionar com a gravidade da doença. Métodos - Trata-se de um estudo transversal, no qual foram avaliados 31 pacientes do sexo masculino com diagnóstico de cirrose hepática compensada em lista de espera para transplante de fígado. O estado nutricional foi avaliado objetivamente por medidas antropométricas através do escore de Mendenhall e classificado segundo Blackburn, subjetivamente por um questionário sistematizado por Detsky e a gravidade da doença pelo escore MELD e CTP. Os oligoelementos plasmáticos (Zn, Se, Cu, Ca, Fe, Mg e Mn) foram analisados pelo método de espectrometria de massas com fonte de plasma indutivamente acoplado (ICP-MS). Para análise estatística foi utilizado o Teste de Mann-Whitney. Resultados - De acordo com a avaliação nutricional 19 (61,3%) estavam com desnutrição e 12 (38,7%) com sobrepeso. Em relação à gravidade da doença 12 (39%) foram classificados como Child A, 17 (55%), Child B e 2 (6%) Child C, sendo 46,9% dos pacientes com o escore MELD >17. Na análise dos oligoelementos 31 (100%) apresentaram níveis de Mn acima dos valores de referência, 23 (74,2%) níveis baixos de Cu, 29 (93,5%) com deficiência de Se, e 31 (100%) níveis baixos de Ca e Mg. Em relação à gravidade da doença não houve diferença estatística entre os oligoelementos estudados, já em relação ao estado nutricional o grupo desnutrido apresentou níveis maiores de Mn (P=0,01) e Fe (P=0,01) e níveis diminuídos de Zn (P=0,03) quando comparado ao grupo sobrepeso. Conclusão - Os resultados mostraram que os oligoelementos estão alterados na doença hepática crônica, sem associação significativa com a gravidade da doença, mas sim com o estado nutricional. A desnutrição está presente nos pacientes estudados, porém um novo cenário com aumento na prevalência de sobrepeso foi verificado independente do grau de descompensação hepática.

Impact of deficient nutrition in bone mass after bariatric surgery / Impacto da deficiência nutricional na massa óssea após cirurgia bariátrica

Background : Essential nutrients are considered for the prevention of the bone loss that occurs after bariatric surgery. Aim : Evaluate nutrients involved in bone metabolism, and relate to serum concentrations of calcium, vitamin D, and parathyroid hormone, and the use of supplements and sun exposure on the bone mass of patients who had undergone gastric bypass surgery. Methods : An observational study, with patients who had undergone the surgery 12 or more months previously, operated group (OG), compared to a control group (CG). Results : Were included 56 in OG and 27 in the CG. The mean age was 36.4±8.5 years. The individuals in the OG, compared to CG, consumed inadequate amounts of protein and daily calcium. The OG had a higher prevalence of low sun exposure, lower levels of 25OH Vitamin D (21.3±10.9 vs. 32.1±11.8 ng/dl), and increased serum levels of parathyroid hormone (68.1±32.9 vs. 39.9±11.9 pg/ml, p<0.001). Secondary hyperparathyroidism was present only in the OG (41.7%). The mean lumbar spine bone mineral density was lower in the OG. Four individuals from the OG had low bone mineral density for chronological age, and no one from the CG. Conclusion : The dietary components that affect bone mass in patients undergoing bariatric surgery were inadequate. The supplementation was insufficient and the sun exposure was low. These changes were accompanied by secondary hyperparathyroidism and a high prevalence of low bone mass in lumbar spine in these subjects.

Racional : Alguns nutrientes são essenciais para a prevenção da perda de massa óssea que ocorre após a cirurgia bariátrica. Objetivo : Avaliar nos pacientes que foram submetidos à cirurgia bariárica pela técnica de bypass gástrico os nutrientes envolvidos no metabolismo ósseo e sua relação com: a concentração sérica de cálcio; a vitamina D e paratormônio; o uso de suplementos alimentares e a exposição solar. Métodos : Estudo observacional com pacientes que foram previamente submetidos à cirurgia, 12 meses ou mais que compuseram o grupo operado (OG), em comparação a um grupo controle (GC). Resultados : Foram avaliados 56 pacientes no OG e 27 no GC. A média de idade foi de 36,4±8,5 anos. Os indivíduos do OG, em comparação com o CG, consumiram diariamente quantidades insuficientes de proteína e cálcio. O OG apresentou maior prevalência de baixa exposição solar, níveis mais baixos de 25OH vitamina D (21,3±10,9 vs 32,1±11,8 ng/ dL) e aumento dos níveis séricos de paratormônio (68,1±32,9 vs 39,9±11,9 pg/ml, p<0,001). Hiperparatiroidismo secundário foi presente apenas no OG (41,7%). A densidade mineral óssea da coluna lombar foi significativamente menor no OG. Quatro indivíduos do OG tiveram baixa densidade mineral óssea comparado com a idade cronológica, e nenhum do CG. Conclusão : Os componentes da dieta que afetam a massa óssea em pacientes submetidos à cirurgia bariátrica estavam inadequados. A suplementação alimentar foi insuficiente e a exposição solar baixa. Estas alterações foram acompanhadas de hiperparatireoidismo secundário e alta prevalência de baixa massa óssea em coluna lombar nestes pacientes.

Efecto biológico de la recuperación nutricional en las concentraciones séricas de citocinas inflamatorias en el niño desnutrido grave / Biological effect of nutritional recovery on serum concentrations of inflammation cytokines in the malnourished child

El niño con desnutrición grave tiene una disfunción de la respuesta inmune que puede aumentar de manera significativa la morbilidad y la mortalidad por infecciones. El objetivo de la presente investigación fue evaluar el efecto de la recuperación nutricional en las concentraciones séricas de citocinas inflamatorias; tales como: interleucina 12 (IL-12), interleucina 17 (IL-17), interferón gamma (IFN-γ) y factor de necrosis tumoral alfa (TNF-α). En un estudio de tipo prospectivo y longitudinal, se seleccionó la población con base a criterios clínicos y antropométricos, constituida por 24 niños desnutridos graves en edades comprendidas entre 1 y 2 años, quienes formaban parte de un programa de recuperación nutricional. La concentración sérica de las citocinas investigadas se determinó antes y después del tratamiento nutricional, empleando la técnica de Inmunoanálisis Enzimático (ELISA) de doble anticuerpo. Para establecer comparaciones se utilizó la t de Student, y se consideró una p<0,05 como estadísticamente significante. Se observó una diferencia en las concentraciones de IL-12, IL-17, IFN-γ y TNF-α antes y después del tratamiento (p<0,05), lo cual parece indicar que la desnutrición per se provoca un estado inflamatorio y que 2 meses de apoyo nutricional intensivo, favorecen no solo la recuperación clínica del niño desnutrido grave, sino también la recuperación de su respuesta inmunitaria en cuanto a la producción de mediadores solubles como son las citocinas.

Children with severe malnutrition have a dysfunction of the immune response that can significantly increase morbidity and mortality from infections. The aim of this investigation was to evaluate the effect of nutritional recovery in serum measurements of inflammatory cytokines; such as interleukin 12 (IL-12), interleukin 17 (IL-17), interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α). In a prospective and longitudinal study, 24 severe malnourished children aged between 1 and 2 years-old, who were part of a program of nutritional recovery, were selected based on clinical and anthropometric criteria. Serum measurements of cytokines were determined before and after dietary treatment, using the technique of sandwich Enzyme-Linked ImmunoSorbent Assay (ELISA). For comparisons, Student’s t test was used, considered p <0.05 as statistically significant. A difference was observed in the concentrations of IL-12, IL-17, IFN-γ and TNF-α before and after treatment (p <0.05), which suggests that malnutrition provokes an inflammatory state and two months of intensive nutritional support, not only promotes the clinical recovery of severe malnourished children, but also the recovery of the immune response with regard to the production of soluble mediators, such as cytokines.

Survival and mortality among users and non-users of hydroxyurea with sickle cell disease / Sobrevida e mortalidade em usuários e não usuários de hidroxiureia com doença falciforme / Sobrevida y mortalidad en usuarios y no usuarios de hidroxiurea con enfermedad falciforme

OBJECTIVE: to estimate survival, mortality and cause of death among users or not of hydroxyurea with sickle cell disease. METHOD: cohort study with retrospective data collection, from 1980 to 2010 of patients receiving inpatient treatment in two Brazilian public hospitals. The survival probability was determined using the Kaplan-Meier estimator, survival calculations (SPSS version 10.0), comparison between survival curves, using the log rank method. The level of significance was p=0.05. RESULTS: of 63 patients, 87% had sickle cell anemia, with 39 using hydroxyurea, with a mean time of use of the drug of 20.0±10.0 years and a mean dose of 17.37±5.4 to 20.94±7.2 mg/kg/day, raising the fetal hemoglobin. In the comparison between those using hydroxyurea and those not, the survival curve was greater among the users (p=0.014). A total of 10 deaths occurred, with a mean age of 28.1 years old, and with Acute Respiratory Failure as the main cause. CONCLUSION: the survival curve is greater among the users of hydroxyurea. The results indicate the importance of the nurse incorporating therapeutic advances of hydroxyurea in her care actions. .

Evolution of the biochemical profile of children treated or undergoing treatment for moderate or severe stunting: consequences of metabolic programming? / Evolução do perfil bioquímico de crianças tratadas ou em tratamento para déficit estatural moderado ou grave: consequências da programação metabólica?

OBJECTIVE: to evaluate changes in the biochemical profile of children treated or being treated for moderate or severe stunting in a nutrition recovery and education center. METHODS: this was a retrospective longitudinal study of 263 children treated at this center between August of 2008 to August of 2011, aged 1 to 6 years, diagnosed with moderate (z-score of height-for-age [HAZ] < -2) or severe stunting (HAZ < -3). Data were collected on socioeconomic conditions, dietary habits, and biochemical changes, as well as height according to age. RESULTS: the nutritional intervention showed an increase in HAZ of children with moderate (0.51 ± 0.4, p = 0.001) and severe (0.91 ± 0.7, p = 0.001) stunting during the monitoring. Increased levels of insulin-like growth factor 1 (IGF-1) (initial: 71.7 ng/dL; final: 90.4 ng/dL; p = 0.01) were also observed, as well as a reduction in triglycerides (TG) in both severely (initial: 91.8 mg/dL; final: 79.1 mg/dL; p = 0.01) and in moderately malnourished children (initial: 109.2 mg/dL; final 88.7 mg/dL; p = 0.01), and a significant increase in high-density lipoprotein cholesterol HDL-C only in the third year of intervention (initial: 31.4 mg/dL; final: 42.2 mg/dL). The values of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels remained high throughout the treatment (initial: 165.1 mg/dL; final: 163.5 mg/dL and initial: 109.0 mg/dL; final: 107.3 mg/dL, respectively). CONCLUSION: the nutritional treatment for children with short stature was effective in reducing stunting and improving TG and HDL-C after three years of intervention. However, the levels of LDL-C and TC remained high even in treated children. It is therefore speculated that these changes may result from metabolic programming due to malnutrition. .

OBJETIVO: avaliar as mudanças no perfil bioquímico de crianças tratadas ou em tratamento para déficit estatural moderado ou grave em um centro de recuperação e educação nutricional. MÉTODOS: estudo longitudinal retrospectivo com 263 crianças semi-internas no Centro no período de agosto/2008 a agosto/2011, com idade entre 1 e 6 anos e diagnóstico de déficit estatural moderado, escore-Z da altura-para-idade (AIZ) < -2 e grave (AIZ < -3). Foram coletados dados socioeconômicos, dietéticos e bioquímicos e a evolução estatural segundo a idade. RESULTADOS: com a intervenção nutricional observou-se incremento no escore-z das crianças com déficit estatural moderado (0,51 ± 0,4; p = 0,001) e grave (0,91 ± 0,7; p = 0,001) durante o período de acompanhamento. Observou-se, ainda, aumento nos níveis de fator de crescimento insulina-símile (IGF-1) (inicial: 71,7 ng/dL; final: 90,4 ng/dL; p = 0,01), redução nos triglicérides (TG) tanto nas crianças graves (inicial: 91,8 mg/dL; final: 79,1 mg/dL; p = 0,01) como nas moderadamente desnutridas (109,2 mg/dL para 88,7 mg/dL; p = 0,01) e aumento significativo do lipoproteína de alta densidade (HDL-C) apenas no terceiro ano de intervenção (inicial: 31,4 mg/dL; final: 42,2 mg/dL). Os valores de colesterol total (CT) e lipoproteína de baixa densidade (LDL-C) continuaram elevados durante todo o tratamento (inicial: 165,1 mg/dL; final: 163,5 mg/dL e inicial: 109,0 mg/dL; final: 107,3 mg/dL, respectivamente). CONCLUSÃO: o tratamento nutricional para as crianças de baixa estatura mostrou-se eficaz na redução do déficit estatural e dos TG e melhora dos níveis de HDL-C após três anos de intervenção. Porém, os níveis de LDL-C e CT mostraram-se sempre elevados mesmo nas ...

Preoperative Nutritional Status of the Surgical Patients in Jeju

BACKGROUND: To assess the preoperative nutritional status of patients with various disorders and to provide data for pre- and postoperative patient management plans, particularly in the elderly. There is no published information on age-matched and disease-matched preoperative nutritional/immunologic status for orthopedic patients, especially in the elderly, in Jeju. METHODS: In total, 331 patients with four categories of orthopedic conditions were assessed: 92 elective surgery patients, 59 arthroplasty patients, 145 patients with fractures, and 35 infection patients. Malnutrition was defined as body mass index (BMI) below 18 kg/m2 of expected body weight (below 20% of normal), serum albumin/globulin ratio below 1.5 (normal range, 1.5 to 2.3), albumin level below 3.5 g/dL, total lymphocyte count below 1,500 cells/mm3, and lymphocyte/monocyte ratio below 5 versus 1. RESULTS: In 92 elective surgery patients, the average BMI was 23 kg/m2, hemoglobin was 15 g/dL, lymphocytes (2,486 cells)/monocytes (465 cells) ratio was 6.1, and the albumin (4.4 g/dL)/globulin (2.5 g/dL) ratio as a protein quotient was 1.7. Among the 59 hip and knee arthroplasty patients, the average BMI was 25 kg/m2, hemoglobin was 12 g/dL, lymphocytes (2,038 cells)/monocytes (391 cells) ratio was 6.6, and albumin (4.1 g/dL)/globulin (2.4 g/dL) ratio was 1.6. No subject showed malnutrition. Among the 145 fracture patients, the average BMI was 23 kg/m2. The hemoglobin level was 13 g/dL, monocytes (495 cells)/lymphocytes (1,905 cells) ratio was 1 versus 4.6, and albumin (4.1 d/gL)/globulin (2.5 d/gL) ratio was 1.6. However, both ratios decreased after 70 years of age. Among the 17 of 35 infection patients, albumin levels were below 3.5 g/dL, the average BMI was 22 kg/m2, lymphocytes (1,532 cells)/monocytes (545 cells) ratio was 2.4 versus 1, and albumin (3.0 g/dL)/globulin (3.3 g/dL) ratio was 0.9, while in 18 patients albumin levels were over 3.5 g/dL, the average BMI was 22 kg/m2, hemoglobin was 12 g/dL, lymphocytes (1,998 cells)/monocytes (583 cells) ratio was 3 versus 1, and albumin/globulin ratio was 1.4. Thus, in the infection group, approximately 50% of the patients showed poor nutrition and immunosuppression. CONCLUSIONS: It was found that nutritional and immune condition deteriorated gradually to some degree in elderly patients over 60 years of age.

Análise comparativa entre a albumina pré- e pós-dialise como indicadores do risco nutricional e de morbimortalidade em hemodiálise / A comparative analysis of pre- and post-dialysis albumin as indicators of nutritional and morbi-mortality risks in haemodialysis patients

INTRODUÇÃO: A albumina pré-diálise pode ter sua utilidade questionada na avaliação do estado proteico devido ao efeito dilucional nesse período. OBJETIVOS: Avaliar se a albumina sérica dosada no período pós-diálise (pós-HD) seria um melhor marcador do estado nutricional e do risco de mortalidade, comparada à albumina pré-diálise. MÉTODOS: Investigou-se a correlação entre a albumina pré- e pós-HD e: o índice de massa corpórea (IMC), a adequação da circunferência muscular do braço (CMB) e da prega tricipital (PCT) ao percentil 50 (P50), proteína C-reativa ultrassensível (hs-PCR), o ângulo de fase (PA), o PNA (equivalente proteico do aparecimento de nitrogênio), o índice de adequação da diálise (Kt/V) e o estado de hidratação (correlação de Pearson). A concordância no diagnóstico do estado nutricional segundo a albumina pré- e pós-HD e o PA foi testada pelo coeficiente Kappa (K) (Bland-Altman). RESULTADOS: Foram incluídos 58 pacientes em hemodiálise (HD) (30 do sexo feminino, com idade média de 49 anos). O IMC, o PA e a hs-PCR apresentaram correlação significativa com a albumina pré- e pós-HD, enquanto a adequação da CMB ao P50 e o PNA o fizeram apenas com a albumina pós-HD. A concordância no diagnóstico de desnutrição, segundo o PA < 5 e albumina pré- e pós-HD < 3,2 g/dL foi regular (K = 0,432). Quando o ponto de corte da albumina para desnutrição foi de 3,7 g/dL (desnutrição leve ou risco de desnutrição), os diagnósticos foram concordantes somente no período pós-HD (K = 0,544). CONCLUSÃO: A albumina pós-diálise parece ser um melhor marcador do estado nutricional e de risco de mortalidade nos casos de desnutrição leve ou risco de desnutrição e nas situações de médio a baixo risco de mortalidade. O estado de hiper-hidratação pré-diálise pode representar um fator de confusão na interpretação clínica da albumina.

INTRODUCTION: Pre-dialysis albumin is likely to be falsely low due to a dilution effect, making its usefulness in assessing protein status questionable. OBJEVTIVES: The purpose of this study was to assess whether post-dialysis albumin would be a better marker of malnutrition and risk of mortality, when compared to pre-dialysis albumin. METHODS: We evaluated the correlation between pre- and post-dialysis albumin and the following parameters: body mass index (BMI), adequacy of muscle arm circumference (MAC) and tricipital skinfold (TS) to the 50th percentile (P50), C-reactive protein (CRP), phase angle (PA), protein equivalent of nitrogen appearance (PNA), the Kt/V index of dialysis adequacy, and the hydration status (Pearson's correlation coefficient). Agreement in the nutritional status according to pre- and post-dialysis (post-HD) albumin and PA was estimated according to the Kappa (K) coefficient (Bland-Altman). RESULTS: A total of 58 haemodialysis (HD) patients were included in this study (30 female; mean age: 49 years). BMI, PA and CRP had a significant correlation with pre- and post-HD albumin, while MAC and PNA correlated only with post-HD albumin. Agreement in the diagnosis of malnutrition according to PA < 5 and pre- and post-HD albumin < 3.2 g/dL was regular (K = 0.432). When using an albumin cut-off value of 3.7 g/dL for malnutrition (mild malnutrition or risk of malnutrition), the diagnosis was concordant only in the post-HD period (K = 0.544). CONCLUSIONS: Post-dialysis albumin levels may be a better marker of protein status and mortality risk in cases of mild malnutrition or risk of malnutrition and in patients with low/medium mortality risk. Pre-dialysis fluid overload may be a confounding factor when evaluating albumin levels.

Malnutrición en niños colombianos con infección por VIH/SIDA / Malnutrition in Colombian children with HIV/AIDS infection

Introducción: La desnutrición (DNT) es una de las complicaciones más tempranas que se presenta en niños con infección por VIH/SIDA, asociada a su morbimortalidad. Igualmente como consecuencia de la terapia antriretroviral y otros medicamentos utilizados, se han encontrado problemas de resistencia a la insulina y obesidad. Objetivo: Determinar la prevalencia de malnutrición (MNT) en niños con infección por VIH/SIDA por carga viral de la Clínica de VIH/SIDA del Hospital Universitario del Valle de Cali, Colombia (HUV) y su posible asociación con algunos factores de riesgo. Metodología: Estudio descriptivo, observacional de corte transversal, con análisis de casos y controles, a quienes se les tomaron datos como carga viral, %CD4, peso y talla. Se categorizó la carga viral (copias/ml) en: <400, ≥400-<300000, ≥30000-<1 millón y ≥1 millón; y el %CD4 en: <15%, ≥15%-<25% y ≥25%. Se consideró DNT global (déficit P/E≥10%), DNT crónica (déficit T/E≥5%), DNT aguda (déficit P/T≥10%) y sobrepeso (exceso P/T≥10%). Resultados: Fueron incluidos 111 niños entre 0 meses y 15 años de edad, con predominio del género masculino (51,3%), con modo de transmisión vertical en 91,8%. El 58.5% tenían entre ≥400-<300000 copias/ml de carga viral; y el 59% presentaron %CD4 ≥25%. La valoración nutricional evidenció DNT global en 64%, DNT aguda en 58%, DNT crónica en 22% y sobrepeso en 18%. Hubo riesgo de 1.7, 1.5 y 2.0 veces más de presentar DNT global, aguda y crónica, respectivamente, si la carga viral era ≥400 copias/ml. Conclusión: En niños con infección por VIH/SIDA por carga viral de la Clínica Pediátrica de VIH/SIDA del HUV de Cali, Colombia, la prevalencia de MNT fue superior al 18%, con una relación positiva superior a 1.5 veces entre carga viral y los diferentes tipos de DNT.

Introduction: Undernutrition (UNT) is a complication that occurs earlier in children with HIV/AIDS associated morbidity and mortality. Also as a result of anti-retroviral therapies and other drugs used, have encountered problems of insulin resistance and obesity. Objective: To determine the prevalence of malnutrition (MNT) in children diagnosed with HIV/AIDS by viral load in the Pediatric Clinic HIV/AIDS at the Hospital Universitario del Valle in Cali, Colombia (HUV) and its possible association with certain risk factors. Methodology: A descriptive cross-sectional study, with case-control analysis, whose data were taken as viral load, CD4%, weight and height. Were categorized viral load (copies / ml): <400, ≥ 400 - <300000, ≥ 30000 - <1 million and ≥ 1 million, and the %CD4 <15%, ≥ 15% - <25% ≥ 25%. UNT is considered global (low W/A≥10%), chronic (low H/A≥5%), acute (low W/H≥10%) and overweight (excess W/H≥10%). Results: We included 111 children from 0 months to 15 years old with male predominance (51.3%), mode of transmission in 91.8%. 58.5% were aged ≥ 400 - <300,000 copies/ml viral load, and 59% had CD4% ≥25%. Nutritional assessment showed 64% global UNT, 58% acute UNT, 22% chronic UNT and 18% overweight. Risk was 1.7, 1.5 and 2.0 times the present global, acute and chronic UNT, respectively, if the viral load was ≥ 400 copies / ml. Conclusion: In children diagnosed with HIV/AIDS by viral load of Pediatric Clinic HIV/AIDS at the HUV in Cali, Colombia, the prevalence of MNT was higher than 18%, with a positive relationship more than 1.5 times between viral load and the different types of UNT.

Clinical and nutritional status of surgical patients with and without malignant diseases: cross-sectional study / Estado clínico e nutricional de pacientes cirúrgicos com e sem doenças malignas: estudo transversal

CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2 percent females and 49.8 percent males). The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5 percent. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001), furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001) and experienced recent weight changes (P<0.0002). Lymphocyte count also differed statistically between the groups (P = 0.0131), which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.

CONTEXTO: A desnutrição em pacientes com doenças malignas é frequentemente observada durante a hospitalização e pode acarretar num aumento do período de internação. OBJETIVO: Comparar o estado nutricional, valores de linfócitos e hemoglobina e o tempo de internação em pacientes com e sem doenças malignas. MÉTODOS: Estudo comparativo com 928 pacientes cirúrgicos com e sem doenças malignas (50,2 por cento do sexo feminino e 49,8 por cento do sexo masculino), sendo analisados os indicadores do estado nutricional como índice de massa corporal, perda de peso recente, contagem de linfócitos, hemoglobina e o tempo de internação. Foi aplicado o teste qui ao quadrado para comparação de proporções e para a comparação de medidas contínuas entre dois grupos e foi aplicado também o teste de Mann-Whitney, com nível de significância de 5 por cento. RESULTADOS: Os pacientes com doenças malignas ficaram internados por mais tempo (P<0.0001), sendo constatado ainda neste grupo, maior percentual de pacientes com índice de massa corporal <18.5 (P<0.0001) e alteração de peso (P = 0.0002). Na contagem de linfócitos, constatou-se diferença estatística entre os grupos (P = 0,0131), sendo os menores valores encontrados entre os pacientes com doenças malignas (P = 0.01). CONCLUSÃO: A contagem de linfócitos, os valores de hemoglobina e a perda ponderal são achados importantes de depleção nutricional em pacientes com doenças malignas.

Importância da avaliação bioquímica mensal na triagem de pacientes com desnutrição em hemodiálise / Importance of the monthly biochemical evaluation to identify patients on hemodialysis with malnutrition

INTRODUÇÃO: A desnutrição é uma complicação frequente nos pacientes em hemodiálise, sendo o diagnóstico precoce importante para reduzir as taxas de morbidade e mortalidade do tratamento. OBJETIVO: Investigar a utilidade dos exames bioquímicos mensais realizados na hemodiálise para triagem de pacientes com desnutrição. MÉTODOS: O diagnóstico nutricional de 252 pacientes foi feito através da avaliação objetiva e subjetiva global, classificando-os em desnutridos e não desnutridos. Paralelamente, durante 4 meses consecutivos, as concentrates de creatinina, fósforo, ureia pré-e pósdiálise e o Kt/V foram registradas para cálculo das médias. Após análise dessas variáveis através da curva ROC, calculouse a sensibilidade e a especificidade na identificação dos pacientes com desnutrição. RESULTADOS: Na curva ROC, a área sob a curva para a ureia foi de 0,683, para o fósforo 0,71, para o Kt/V 0,724 e para a creatinina 0,765. Para valores de ureia < 90 mg/dL; fósforo < 4,2 mg/dL; Kt/V > 1,6 e creatinina < 6,5 mg/dL, a especificidade variou entre 80 por cento e 88 por cento e a sensibilidade entre 26 por cento e 51 por cento . O valor preditivo negativo variou entre 90 por cento e 92 por cento e o valor preditivo positivo entre 23 por cento e 32 por cento. A associação de dois ou mais desses índices não modificou de forma significante esses valores. CONCLUSÕES: Nossos resultados sugerem que valores de ureia < 90 mg/dL, creatinina < 6,5 mg/dL, fósforo < 4,2 mg/dL e Kt/V > 1,6 podem ser utilizados para triagem de pacientes com desnutrição.

INTRODUCTION: Malnutrition is a frequent complication in patients on hemodialysis and early diagnosis is important to reduce the morbidity and mortality of treatment. OBJECTIVE: To investigate the usefulness of biochemical tests performed monthly in order to identify hemodialysis patients with malnutrition. METHODS: The nutritional status of 252 patients was evaluated by objective and subjective global assessment, and the patients classified as malnourished and not malnourished. Then, during 4 consecutive months, serum creatinine, phosphorus, urea pre-and post-dialysis and Kt/V were recorded for calculation of averages. After analysis of these variables by the RO C curve we calculated the sensitivity and specificity of these parameters to identify patients with malnutrition. RESULTS: In ROC curve, the area under the curve for urea was 0.683, 0.71 for phosphorus, 0.724 for Kt/V and 0.765 for creatinine. For values of urea < 90 mg/dL, phosphorus < 4.2 mg/dL, Kt/V > 1.6 and creatinine < 6.5 mg/dL, the specificity ranged between 80 percent and 88 percent and sensitivity between 26 percent and 51 percent. The negative predictive value ranged between 90 percent and 92 percent and positive predictive value between 23 percent and 32 percent. The association of two or more of these índices did not change significantly these values. CONCLUSIONS: Our results suggest that serum urea < 90 mg/dL, creatinine < 6.5 mg/dL, phosphorus < 4.2 mg/dL, and Kt/V > 1.6 can be used for screening patients with malnutrition. However, using these cutoffs the parameters tend to overestimate the number of patients with malnutrition.

Prenatal multiple micronutrient supplementation impact on biochemical indicators during pregnancy and postpartum / Efecto de la suplementación prenatal con micronutrimentos múltiples en indicadores bioquímicos durante el embarazo y el posparto

Objective. The objective of this analysis was to test the impact of daily supplementation with multiple micronutrients (MM) during pregnancy on Zn, vitamin A and folate status compared to iron only (Fe). Material and Methods. The study was carried out during 1997-2000 in a semi-urban community in Morelos state, Mexico. Women were randomly assigned to MM (n= 249) or Fe (n= 258) and received supplements daily (6 d/wk) under supervision by the field team from recruitment (approximately 9 weeks pregnancy) until delivery. Blood samples were collected on a sub-sample of women at baseline, 32 weeks pregnancy and one month postpartum (1PP) and assessed for serum zinc, retinol and whole blood folate (baseline and 1PP only). A breast milk sample was extracted at 1PP and assessed for retinol content. Result. At baseline there was no significant difference between supplementation groups in mean Zn, retinol or folate concentrations or the prevalence of deficiencies (Zn 12.2%, vitamin A 2.8%, folate 5.3%). Mean change in Zn and retinol concentrations from baseline to 32 weeks pregnancy did not differ between groups or between baseline and 1PP for Zn, retinol or folate. At 1PP, there was a tendency (p= 0.09) towards a lower prevalence of folate deficiency/depletion in the MM group (10.0%) than the Fe group (18.5%). Conclusions. MM supplementation during pregnancy did not improve zinc or vitamin A status compared to Fe only. There is some indication that folate status may have improved with MM supplementation despite low prevalence of deficiency. While lack of response in serum retinol may be explained by generally adequate status, the lack of impact on zinc status requires further exploration.

Objetivo. Evaluar el efecto de la suplementación diaria con múltiples micronutrimentos (MM) durante el embarazo en el estado de zinc, vitamina A y folato comparado con la suplementación sólo con hierro (Fe). Material y métodos. El estudio se realizó en una comunidad semiurbana en el estado de Morelos, México, entre 1997 y 2000. Las mujeres fueron asignadas aleatoriamente a recibir un suplemento de MM (n= 249) o Fe (n= 258) diariamente (6 días/semana), cuyo consumo fue supervisado por personal de campo, desde la evaluación basal (aproximadamente 9 semanas de gestación) hasta el parto. En una submuestra de mujeres participantes, se tomaron muestras de sangre venosa, a las 9 y 32 semanas de embarazo y al mes posparto (1PP). Se midieron las concentraciones séricas de zinc y retinol y la concentración de folato en sangre total, esta última sólo en la evaluación basal y al 1PP. Además se colectó una muestra de leche materna al 1PP, en donde se midió la concentración de retinol. Resultados. En la evaluación basal no hubo diferencias significativas entre grupos en las concentraciones promedio de zinc y retinol, ni en la concentración de folato o en la prevalencia de deficiencias (Zn 12.2%, vitamina A 2.8%, folato 5.3%). El cambio promedio en zinc y retinol de la evaluación basal a la semana 32 de embarazo, no fue diferente entre grupos, tampoco entre la evaluación basal y al 1PP en zinc, retinol o folato. Al 1PP hubo una tendencia (p= 0.09) a menor prevalencia de deficiencia/depleción de folato en el grupo de MM (10.0%) que en el grupo Fe (18.5%). Conclusiones. La suplementación con MM durante el embarazo no mejoró el estado de zinc y vitamina A comparada con la suplementación sólo con Fe. Sin embargo, el estado de folato puede haber mejorado con la suplementación con MM, a pesar de la baja prevalencia de deficiencia de folato. La falta de efecto...

Ethanol in low chronic dose level attenuates major organic effects in malnourished rats

The aim of the present study was to evaluate the chronic toxicity of ethanol low blood levels in malnourished rats. Female Wistar rats (220 g) were subjected to either an ad libitum diet (W, well-nourished, n=10) or food restriction (M, malnourished, n=10). Water (WW and MW) or ethanol solution (W5 percent and M5 percent) was offered to half of each nutritional group (n=5) as the only fluid source. The treatment was continued for two months. After sacrifice, blood biochemical parameters and macroscopic, histologic and morphometric evaluation of the liver were performed. Results indicated that: Ethanol consumption was higher in malnourished rats and minimized body weight loss in malnourished rats, while it decreased the body weight gain in well-nourished ones. Behavioral ethanol intoxication was more severe in malnourished rats. Malnutrition decreased hematocrit and hemoglobin but, on the other hand, ethanol was a protective factor of that effect (hemoglobin: MW 10.6 mg/dl / ME 13.02 mg/dl, p< 0.05). Ethanol increased the relative liver weight of both well-nourished and malnourished rats. Ethanol intake minimized iron pigment, collagen area and binuclear hepatocyte/ field increased by malnutrition. These data are in accordance with previous reports which showed ethanol as an important source of calories and, even chronically, ethanol still attenuates the effects of malnutrition.

Programação neonatal do perfil lipídico em ratos e ovelhas / Neonatal programming to lipids profile in rats and sheeps

A nutrição na lactação é um importante fator de impressão para futuras alterações hormonais e metabólicas no desenvolvimento, que vai regular a composição corporal, a homeostase glicêmica e o perfil hormonal dos animais, caracterizando o processo de programação. Nesta etapa crítica da vida, a desnutrição ou o excesso de nutrientes modificam a secreção e ação de vários hormônios, especialmente a prolactina, leptina e hormônios tireóideos. Apesar dos diversos estudos epidemiológicos mostrando que o perfil lipídico pode ser programado por alterações nutricionais na gestação e lactação, contribuindo para maior risco de doenças cardiovasculares, poucos estudos exerimentais foram realizados. Assim, avaliamos a programação do perfil lipídico em diversos modelos de impressão nutricional e hormonal em ratos e ovelhas, relacionando a programação da massa e composição corporal e homeostase glicêmica. Estudamos seis modelos de programação, a saber: a) desnutrição protéica materna na lactação (dieta com 8 porcento de proteína); b) bloqueio da prolactina no fim da lactação, com o uso de bromocriptina; c) supernutrição na lactação por redução da ninhada (3 vs. 10 filhotes); d) injeção de leptina aos filhotes (8ug/100g peso corporal/dia, nos dez primeiros dias de lactação); e) exposição materna à nicotina (6 mg/kg de massa corporal/dia) na lactação; f) desnutrição protéica e calórica materna de ovelhas na lactação. Os ratos programados pela restrição protéica materna ganham menos massa corporal, menos gordura total e visceral, apresentam menor glicemia e insulinemia e a única alteração programada no perfil lipídico foi a menor concentração sérica de colesterol total (16 porcento). Os ratos cuja prolactina materna foi bloqueada ganharam mais massa corporal, maior gordura total e visceral, apresentaram maior índice de resistência à insulina e menor adiponectinemia, que se refletiu em um perfil lipídico bastante alterado, com elevação do colesterol total (30 porcento)...

Nutritional status on lactation is an important imprinting factor for future hormonal and metabolic changes during development, regulating body composition, glucose homeostasis and hormonal profile in animals, characterizing the programming effect. In this critical period of life, malnutrition or overnutrition changes the secretion and action of several hormones, such as prolactin, leptin and thyroid hormones. Although several epidemiologic studies confirm the programming effect upon the lipids profile in humans, caused by nutritional imprinting during gestation of lactation that can contribute to a higher risk of cardiovascular diseases, few experimental data was reported. Thus, our main objective was to study the lipid profile in several models of nutritional and hormonal imprinting in rats and ovine, related to the programming of body mass and composition and glucose homeostasis. We studied 6 models of programming: a) maternal protein malnutrition (8 percent protein); b) prolactin blockade at the end of lactation by bromocriptine c) early overnutrition on lactation by litter size reduction (3 vs. 10 pups); d) leptin injection to the pups (8 ug/100g body weight/day, for the first 10 days of lactation); e) maternal nicotine administration (6mg/Kg body mass/day) during lactation; f) ewes maternal protein (8 percent) or energie (60 percent) restriction during lactation. The programmed offspring whose mother were protein-restricted during lactation gain less body mass, and when they were 180 days-old, showed lower total and visceral fat mass, lower serum glucose and insulin and lower total cholesterol (-16 percent). The prolactin blockadge programmed for higher body mass, total and visceral fat mass, higher insulin resistance index and lower serum adiponectin, these effects were associated to several changes in the lipid profile, such as higher total cholesterol (30 percent), LDL-c (1,5X), VDLc (46 percent), triglycerides (49 percent) and lower HDLc...

Hospital malnutrition and inflammatory response in critically ill children and adolescents admitted to a tertiary intensive care unit

Critical illness has a major impact on the nutritional status of both children and adults. A retrospective study was conducted to evaluate the incidence of hospital malnutrition at a pediatric tertiary intensive care unit (PICU). Serum concentrations of IL-6 in subgroups of well-nourished and malnourished patients were also evaluated in an attempt to identify those with a potential nutritional risk. METHODS: A total of 1077 patients were enrolled. Nutritional status was evaluated by Z-score (weight for age). We compared mortality, sepsis incidence, and length of hospital stay for nourished and malnourished patients. We had a subgroup of 15 patients with severe malnutrition (MN) and another with 14 well-nourished patients (WN). Cytokine IL-6 determinations were performed by enzyme-linked immunosorbent assay. RESULTS: 53 percent of patients were classified with moderate or severe malnutrition. Similar amounts of C- reactive protein (CRP) were observed in WN and MN patients. Both groups were able to increase IL-6 concentrations in response to inflammatory systemic response and the levels followed a similar evolution during the study. However, the mean values of serum IL-6 were significantly different between WN and MN patients across time, throughout the study (p = 0.043). DISCUSSION: a considerable proportion of malnourished patients need specialized nutritional therapy during an intensive care unit (ICU) stay. Malnutrition in children remains largely unrecognized by healthcare workers on admission. CONCLUSIONS: The incidence of malnutrition was very high. Malnourished patients maintain the capacity to release inflammatory markers such as CRP and IL-6, which can be considered favorable for combating infections On the other hand, this capacity might also have a significant impact on nutritional status during hospitalization.

Estado nutricional e anemia em crianças Suruí, Amazônia, Brasil / Nutritional status and anemia in Suruí Indian children, Brazilian Amazon

OBJETIVO: Analisar o perfil nutricional de crianças indígenas Suruí menores de 10 anos através da antropometria e da dosagem de hemoglobina. MÉTODOS: A pesquisa foi conduzida em fevereiro-março de 2005 na Terra Indígena Sete de Setembro, na fronteira de Rondônia com Mato Grosso. Estatura e peso foram obtidos segundo técnicas padronizadas e comparados à referência do National Center for Health Statistics (n = 284). A concentração da hemoglobina foi determinada utilizando beta-hemoglobinômetro portátil (Hemocue) (n = 268). RESULTADOS: As porcentagens de crianças com déficit (escore z < -2) nos índices estatura para idade, peso para idade e peso para estatura foram 25,4, 8,1 e 0 por cento, respectivamente. Nas menores de 5 anos, foram 31,4, 12,4 e 0 por cento, respectivamente. A ampla maioria das crianças estava anêmica (80,6 por cento), alcançando 84,0 por cento naquelas de 6 a 59 meses de idade. CONCLUSÕES: Os resultados apontam para um quadro de alta prevalência de desnutrição e anemia nas crianças Suruí. A comparação com resultados de inquérito anterior indica que houve redução expressiva na prevalência de baixa estatura para idade entre 1987 e 2005 (de 46,3 para 26,7 por cento nas crianças menores de 9 anos). Por sua vez, 3,9 por cento das crianças apresentaram sobrepeso em 2005, o que não foi observado em 1987. As prevalências de anemia não se modificaram substancialmente entre os dois períodos. Apesar das melhoras observadas no perfil antropométrico, as prevalências de déficits nutricionais ainda permanecem muito mais elevadas que as observadas na população brasileira em geral. Impõe-se a necessidade da implantação de atividades sistemáticas e regulares de monitoramento do crescimento e desenvolvimento das crianças indígenas, com ênfase na vigilância nutricional.

OBJECTIVE: To assess the nutritional status of Suruí Indian children aged less than 10 years by means of anthropometric measurements and determination of hemoglobin concentration levels. METHODS: The study was carried out from February to March 2005 in the Sete de Setembro Indian Reservation, located on the boundary between the states of Rondônia and Mato Grosso, Amazonia, Brazil. Height and weight were measured according to standard procedures and then compared with the National Center for Health Statistics reference values (n = 284). Hemoglobin concentration was determined by a portable beta-hemoglobinometer (Hemocue) (n = 268). RESULTS: The percentages of children > -2 z scores for height for age, weight for age and weight for height were 25.4, 8.1 and 0 percent, respectively. For children aged less than 5 years, the percentages were 31.4, 12.4 and 0 percent. Most children had anemia (80.6 percent), with a rate of up to 84.0 percent among those aged 6 to 59 months. CONCLUSIONS: There is a high prevalence of protein-energy undernutrition and anemia among Suruí children. Comparison with a previous survey indicated that the prevalence of height for age deficit significantly decreased between 1987 and 2005 (from 46.3 to 26.7 percent in children younger than 9 years). On the other hand, 3.9 percent of the children were overweight in 2005, a finding that had not been reported in 1987. The prevalence of anemia did not change remarkably between these years. Despite the improvement in anthropometric parameters, the prevalence of nutritional deficit has been persistently higher than that observed in the Brazilian population at large. It is therefore necessary that systematic and regular monitoring of indigenous children's growth and development be implemented, focusing mainly on nutritional surveillance.
