RESUMEN Objetivo Evaluar el cumplimiento de los lineamientos para la desnutrición aguda, moderada y severa en menores de cinco años del Departamento de Córdoba (Colombia). Materiales y Métodos Se realizó un estudio descriptivo correlacional de corte transversal. Participaron 23 Unidades Primarias Generadoras de Datos (UPGD) de instituciones públicas que diligenciaron una encuesta física de acuerdo con los lineamientos de la normativa vigente, con un nivel de confianza de 95% y un máximo error permisible de 5%. Resultados El 83% de las UPGD públicas no realiza búsquedas activas institucionales. El 74% no realiza mantenimiento de los equipos de medidas antropométricas. El 78% no garantiza la prescripción de la Fórmula Terapéutica Lista para el Consumo (FTLC). El 83% no presta la atención en salud con calidad. El 78% de los profesionales no está adherido al lineamiento técnico. Conclusiones Los resultados son concluyentes, no hay adherencia e implementación de los lineamientos en las UPGD públicas y esto se refleja en la atención y los casos notificados al Sistema de Vigilancia Epidemiológica. Algunos reactivos se cumplen en su totalidad, pero estos no se reflejan en la atención integral.

ABSTRACT Objective To evaluate compliance with the guidelines for the management of acute, moderate, and severe malnutrition in children under five years of age in the department of Córdoba (Colombia). Materials and Methods A cross-sectional correlational descriptive study was conducted with 23 Primary Data Generating Units (UPGD) from public institutions participating. The study involved completing a physical survey in accordance with the guidelines of the current standard, with a confidence level of 95% and a maximum permissible error of 5% Results 83% of the public UPGD do not carry out active institutional searches.74% do not perform maintenance on anthropometric measurement equipment. 78% do not guarantee the prescription of the therapeutic formula ready for consumption. Additionally, 83% do not provide quality healthcare, and 78% of professionals do not adhere to the technical guideline. Conclusions The results are conclusive: there is a lack of adherence to and implementation of guidelines in public UPGD, and this is reflected in the quality of care provided and in the cases reported to the Epidemiological Surveillance System. While some criteria are fully met, they do not contribute to comprehensive care.

Effects of perinatal protein restriction on the oxidative balance in the hypothalamus of 60-day-old rats / Efeitos da restrição proteica perinatal sobre o balanço oxidativo no hipotálamo de ratos de 60 dias de idade

ABSTRACT Objective Evaluate the effects of maternal low-protein diet on the oxidative stress in the hypothalamus of 60-day-old rats. Methods Male Wistar rats were divided into two experimental groups according to the mother's diet during pregnancy and lactation; control group (NP:17% casein n=6) and a malnourished group (LP:8% casein n=6). At 60 days of life, the rats were sacrificed for the collection of the hypothalamus for further biochemical analysis. Results Our results showed an increase in oxidative stress in malnourished group, observed through an increase in carbonyl content (p=0.0357), a reduction in the activity of the glutathione-S-transferase enzyme (p=0.0257), and a reduction in the non-enzymatic antioxidant capacity evidenced by the decrease in the ratio reduced glutathione/oxidized glutathione (p=0.0406) and total thiol levels (p=0.0166). Conclusion A low-protein diet during pregnancy and lactation is closely associated with increased oxidative stress and reduced antioxidant capacity in the hypothalamus of sixty-day-old rats.

RESUMO Objetivo Avaliar os efeitos da restrição proteica materna sobre o estresse oxidativo no hipotálamo de ratos de 60 dias de idade. Métodos Ratos Wistar machos foram divididos em dois grupos experimentais de acordo com a dieta da mãe durante a gestação e lactação: grupo controle (NP: 17% caseína n=6) e grupo desnutrido (LP: 8% caseína n=6). Aos 60 dias de vida, os ratos foram sacrificados para coleta do hipotálamo para posterior análise bioquímica. Resultados Os resultados demonstraram aumento do estresse oxidativo no grupo desnutrido, observado através do aumento do conteúdo de cabonilas (p=0,0357) e redução da atividade da enzima glutationa-S-transferase (p=0,0257) e da capacidade antioxidante não enzimática, evidenciada pela queda da razão glutationa reduzida/glutationa oxidada (p=0,0406) e dos níveis de tióis totais (p=0,0166). Conclusão Uma dieta com baixo teor de proteínas durante a gestação e lactação está intimamente associada ao aumento do estresse oxidativo e à redução da capacidade antioxidante no hipotálamo de ratos de 60 dias de vida.

Eye movement impairments in children with malnutrition.

Malnutrition is characterised by deficient nutrient ingestion and absorption and is still one of the most important causes of morbidity and mortality in children worldwide. Our main rationale was that protein-energy malnutrition (PEM) may affect eye movement in children with malnutrition. Twenty children without PEM (mean age = 10.8; SD = 1.0 years) and 18 children with PEM (mean age = 10.9; SD = 1.2 years) were included in the present study. We applied three types of tests: one that consisted of a maze and two versions of the Spot the Seven Errors test using boats and elephants. Our results indicated that children with PEM exhibited performance deficits in the maze test (p < .001) and Spot the Seven Errors test for both boats (p < .001) and elephants (p < .001). These data suggest that nutritional impairments during the first year of life (i.e., a critical period) can directly impact eye movement. Eye tracking is a reliable technique to investigate higher-order processes, but our results should be interpreted with caution. Our findings highlight the relevance of cognitive development in malnourished children, which can negatively affect their development. Screening, assessment and rehabilitation strategies are essential in this at-risk population.

Desnutrição na cirrose: associação com a etiologia e disfunção hepatocelular / Malnutrition in cirrhosis: association with etiology and hepatocellular dysfunction

ABSTRACT BACKGROUND: The protein-energy malnutrition alters the prognosis of patients with cirrhosis. Its prevalence may vary according to the etiology of liver disease, it´s severity and the evaluation of the method applied. The infection by the hepatitis C virus (HCV) and alcoholism are the main etiologies of cirrhosis and result in a significant morbidity and mortality. OBJECTIVE: To evaluate the nutritional status of patients with cirrhosis according the liver disease etiology and severity. METHODS: It is a prospective study, in which the sample was for convenience and consisted of patients with cirrhosis, infected by HCV or alcoholic etiology. The nutritional status evaluation was carried out through anthropometry, food consumption, bioelectrical impedance (BIA) and subjective global assessment (SGA). The anthropometric data evaluated were weight, height, body mass index (BMI), triceps skinfold (TSF), circumference of the arm (CA), non-dominant handshake strength (FAM) and the adductor pollicis muscle thickness (APM). Patients were classified according to the severity of liver disease, using the Child-Pugh and Model for End-stage Liver Diseases (MELD) scores. RESULTS: Ninety patients with cirrhosis were evaluated, 47 with HCV and 43 with alcoholic etiology. The prevalence of protein-calorie malnutrition ranged from 10.9% to 54.3% in the HCV group and from 4.7% to 20.9% in the alcoholic group, depending on the method used for evaluation. The group with HCV infection presented a higher malnutrition prevalence in comparison to the alcoholic in the following evaluations: TSF (P<0.001), phase angle (PA) (P=0.016) and SGA (P=0.010). PA values were lower in patients with viral cirrhosis (5.68±1.05) when compared to those with alcoholic etiology (6.61±2.31) (P=0.016). When all patients were analyzed, regardless of etiology, an inversely correlation was observed among Child-Pugh score and PA values (P=0.018). CONCLUSION: HCV cirrhosis showed worse nutritional parameters in comparison to alcoholic etiology; however, the PA was associated with worse liver function in both etiologies.

RESUMO CONTEXTO: A desnutrição proteico-calórica altera o prognóstico dos pacientes com cirrose. Sua prevalência pode variar de acordo com a etiologia da hepatopatia, gravidade da doença e o método de avaliação empregado. A infeção pelo vírus da hepatite C (VHC) e o alcoolismo, estão entre as principais etiologias da cirrose e acarretam significativa morbidade e mortalidade. OBJETIVO: Avaliar o estado nutricional do paciente com cirrose de acordo com a etiologia e gravidade da hepatopatia. MÉTODOS: Estudo prospectivo, em que a amostra foi por conveniência constituída de pacientes com cirrose, infectados pelo vírus da hepatite C (VHC) ou etiologia alcoólica. A avaliação do estado nutricional foi realizada através da antropometria, consumo alimentar, bioimpedância elétrica (BIA) e da avaliação subjetiva global (ASG). Os dados antropométricos avaliados foram: peso, altura, índice de massa corporal (IMC), prega cutânea triciptal (PCT), circunferências do braço (CB), força do aperto de mão não dominante (FAM) e a espessura do músculo adutor do polegar (MAP). Os pacientes foram classificados de acordo com a gravidade da hepatopatia, através do escore Child-Pugh e Model for End-stage Liver Diseases (MELD). RESULTADOS: Foram avaliados 90 pacientes com cirrose, 47 com etiologia pelo VHC e 43 com etiologia alcoólica. A prevalência de desnutrição proteico-calórica variou de 10,9% a 54,3% no grupo do VHC e de 4,7% a 20,9% no grupo dos alcoolistas, dependendo do método utilizado para avaliação. O grupo com infecção pelo VHC apresentou maior prevalência de desnutrição em relação ao de etiologia alcoólica nas seguintes avaliações: PCT (P<0,001), ângulo de fase (AF) (P=0,016) e ASG (P=0,010). Os valores do AF foram menores nos pacientes com cirrose viral (5,68±1,05) quando comparados aos com etiologia alcoólica (6,61±2,31) (P=0,016). Quando analisados todos os pacientes, independente da etiologia da hepatopatia, observou-se uma correlação inversamente proporcional entre a classificação de Child-Pugh e os valores de AF (P=0,018). CONCLUSÃO: A cirrose pelo VHC demonstrou piores parâmetros nutricionais em relação à etiologia alcoólica; entretanto, em ambas etiologias o AF foi associado com pior função hepática em ambas etiologias.

Stunting and overweight among children in Northeast Brazil: prevalence, trends (1992-2005-2015) and associated risk factors from repeated cross-sectional surveys.

BACKGROUND: A study involving children from Alagoas (Northeast Brazil) revealed that, as a consequence of a drastic reduction in the prevalence of stunting between 1992 to 2005, (22.5 to 11.4%) combined with an increase in overweight prevalence (6.7 to 9.3%), the prevalence of these two conditions in 2005 was very close. If these trends were maintained, it is very likely that, at this time, the childhood overweight prevalence has already exceeded that of the stunting. However, no study is available to confirm this hypothesis. The identification of these changes is relevant to the planning and evaluation of public policies. This study aimed to investigate the prevalence, time trends and associated factors with stunting and overweight in children from Alagoas. METHODS: Independent cross-sectional household surveys were conducted in 1992 (n = 1231), 2005 (n = 1381) and 2015 (n = 988). Data were collected from probabilistic samples of children aged 0-60 months. Stunting was defined by stature-for-age < - 2 sd and overweight by weight-for-stature > 2 sd. RESULTS: Between 1992, 2005 and 2015, the stunting prevalence was 22.6, 11.2 and 3.2% (reduction of 85.8%), while the overweight prevalence was 6.9, 7.5 and 14.9% (increase of 115.9%), respectively. After multivariate analysis, the following positive associations with stunting were observed in 1992: age group > 24 months (28.3% vs 14.5%), mother with ≥2 children (28.8% vs 12.8%), low birth weight (28.3% vs 15.7%) and mother with low schooling (29.3% vs 7.2%). In 2015 there was a higher prevalence of stunting in males (4.2% vs 2.2%), in children < 24 months (4.6% vs 2.2%), with low birth weight (8.6% vs 3.0%) and in those who had mothers with low schooling (7.0% vs 2.6%). Regarding overweight, in 1992 there was higher prevalence for male (9.1% vs 4.7%) and in children whose mothers had ≤2 children (8.9% vs 5.8%), while in 2015 only birth weight >  4 kg was associated to overweight (27.3% vs 14.2%). CONCLUSIONS: During the analyzed period, there was a significant decrease in stunting prevalence. At the same time, a substantial increase was observed in the overweight prevalence. Currently, stunting is a problem of low magnitude, while overweight has become a worrying public health problem.

Etiología y mecanismos de desnutrición en el paciente cirrótico / Etiology and mechanisms of undernourishment in the cirrhotic patient

RESUMEN El hígado juega un rol en la homeostasis calórica; está comprometido en el proceso digestivo, y es frecuente encontrar desnutrición en la cirrosis, por incapacidad para satisfacer sus requerimientos de macro y micronutrientes. La patogénesis de desnutrición en la cirrosis es multifactorial, compleja y difícil de ser comprendida, incluye ingesta reducida de nutrientes, biosíntesis disminuida, aumento de la perdida de proteína, absorción intestinal deficiente, disturbios en la utilización del substrato, anormalidades en el metabolismo de carbohidratos, lípidos y proteínas así como aumento de citoquinas pro inflamatorias, resultando en hipermetabolismo y aumento del gasto proteína-energía y de los requerimientos. La evaluación nutricional es trascendental para un enfoque clínico-terapéutico, por su implicancia pronóstica y la respuesta al trasplante hepático. Aún con la evidencia de la prevalencia de desnutrición en cirróticos, continúa poco reconocida, poco diagnosticada y muy poco tratada. Existe controversia si la desnutrición puede ser revertida en cirróticos; aunque hay un acuerdo sobre la necesidad de mejorar la ingesta de alimentos evitando las limitaciones y restricciones no basadas en la evidencia.

ABSTRACT The liver plays a role in the caloric homeostasis; it is involved in the digestive process, so it is not surprising to find malnutrition in cirrhosis, because they have an inability to meet their macro and micronutrient requirements. The pathogenesis of malnutrition is multifactorial and complex and frequently difficult to understand and includes reduced nutrient intake, decreased protein biosynthesis and increased loss, poor intestinal absorption, disturbances in the use of the substrate, abnormalities in the metabolism of carbohydrates, lipids and proteins and increased of pro-inflammatory cytokines resulting in a hypermetabolic state as well as increase in protein-energy expenditure and requirements. The evaluation of nutritional status is transcendental for a clinical-therapeutic approach, due to its influence on the prognosis and response to liver transplantation. Despite the evidence on the prevalence of malnutrition in liver cirrhosis, this condition remains poorly recognized, poorly diagnosed and poorly treated. It is controversial, if malnutrition can be reversed in cirrhotic; there is an agreement about the need to improve the food intake, avoiding limitations and restrictions that are not based on evidence.

Anorexia nervosa con desenlace fatal: a propósito de un caso / Anorexia nervosa with fatal outcome: A case report

Resumen La Anorexia Nervosa (AN) es el trastorno psiquiátrico con mayor nivel de mortalidad directa y, a la vez, causa de múltiples y riesgosas complicaciones somáticas tales como: bradicardia, hipotensión ortostática, arritmias cardiacas, hipoglicemia, falla hepática, alteraciones hidroelectrolíticas y hormonales, osteopenia, dilatación gástrica y, finalmente, muerte súbita por diferentes causas. A pesar de su prevalencia relativamente baja, afecta a personas jóvenes con larga expectativa de vida. Su manejo, cuando llega a niveles de gravedad severa (IMC < 15), es complejo, pues requiere trabajo conjunto de psiquiatría y otras especialidades médicas y puede tener consecuencias ominosas. Se presenta y discute el caso de una paciente mujer de 19 años cuyo IMC llegó a 11 y que, lamentablemente, falleció mientras recibía atención hospitalaria. Se revisan las principales complicaciones médicas de la AN, remarcándose la necesidad de considerar los parámetros pertinentes para una atención hospitalaria oportuna que pueda evitar desenlaces fatales.

Summary Anorexia Nervosa (AN) is the psychiatric disorder with the highest direct mortality level and, at the same time, the cause of multiple and risky somatic complications such as bradycardia, orthostatic hypotension, cardiac arrhythmias, hypoglycemia, liver failure, hydro-electrolytic and hormonal disorders, osteopenia, gastric dilation and, finally, sudden death from different causes. Despite its relatively low prevalence, it affects young people with a long life expectancy. Its medical management, when reaching a high severity level (BMI <15), is complex as it requires joint work between psychiatry and other medical specialties, and can even have ominous consequences. The case of a 19-year-old woman whose BMI was around 11, and who unfortunately died while receiving hospital care, is discussed. The main complications of AN are reviewed, and the need to consider the relevant parameters for a timely hospital care are highlighted, in order to avoid fatal outcomes.

Nutritional Treatment of a Young Infant with Cystic Fibrosis Presenting with Severe Kwashiorkor Dermatosis.

Kwashiorkor in infancy is typically associated to an underlying disease. Edema, a striking feature of this type of malnutrition, can be difficult to assess in this age group. The typical dermatosis of Kwashiorkor is not fully explained the deficiency of one isolated vitamin or micronutrient. This article presents an infant with cystic fibrosis, who developed Kwashiorkor in the third month of life with extensive cutaneous manifestations. An early, individualized and aggressive nutritional intervention with optimized supplementationof sulfur amino acids, vitamins and micronutrients was established, with impressively recovery of overall nutrition and skin manifestations in a relatively short period of time.

Prognóstico e avaliação nutricional de doentes com doença hepática crônica com recurso à antropometria e avaliação global subjetiva / Outcome and nutritional assessment of chronic liver disease patients using anthropometry and subjective global assessment

ABSTRACT BACKGROUND: Protein-calorie malnutrition is common in chronic liver disease (CLD) but adequate clinical tools for nutritional assessment are not defined. OBJECTIVE: In CLD patients, it was aimed: 1. Characterize protein-calorie malnutrition; 2. Compare several clinical, anthropometric and functional tools; 3. Study the association malnutrition/CLD severity and malnutrition/outcome. METHODS: Observational, prospective study. Consecutive CLD ambulatory/hospitalised patients were recruited from 01-03-2012 to 31-08-2012, studied according with age, gender, etiology, alcohol consumption and CLD severity defined by Child-Turcotte-Pugh. Nutritional assessment used subjective global assessment, anthropometry, namely body-mass index (BMI), triceps skinfold, mid upper arm circumference, mid arm muscular circumference and handgrip strength. Patients were followed during two years and survival data was recorded. RESULTS: A total of 130 CLD patients (80 men), aged 22-89 years (mean 60 years) were included. Most suffered from alcoholic cirrhosis (45%). Hospitalised patients presented more severe disease ( P <0.001) and worst nutritional status defined by BMI ( P =0.002), mid upper arm circumference ( P <0.001), mid arm muscular circumference ( P <0.001), triceps skinfold ( P =0.07) and subjective global assessment ( P <0.001). A third presented deficient/low handgrip strength. Alcohol consumption ( P =0.03) and malnutrition detected by BMI ( P =0.03), mid upper arm circumference ( P =0.001), triceps skinfold ( P =0.06), mid arm muscular circumference ( P =0.02) and subjective global assessment ( P <0.001) were associated with CLD severity. From 25 patients deceased during follow-up, 17 patients were severely malnourished according with triceps skinfold. Malnutrition defined by triceps skinfold predicted mortality ( P <0.001). CONCLUSION: Protein-calorie malnutrition is common in CLD patients and alcohol plays an important role. Triceps skinfold is the most efficient anthropometric parameter and is associated with mortality. Nutritional assessment should be considered mandatory in the routine care of CLD patients.

RESUMO CONTEXTO: A desnutrição calórico-proteica é frequente na doença hepática crônica (DHC), no entanto, ferramentas clínicas adequadas para avaliação nutricional destes doentes não estão definidas. OBJETIVO: Em doentes com DHC, pretendeu-se: 1. Caracterizar a desnutrição calórico-proteica; 2. Comparar diferentes ferramentas clínicas, antropométricas e funcionais de avaliação nutricional; 3. Estudar a associação desnutrição/gravidade da DHC e desnutrição/prognóstico. MÉTODOS: Estudo observacional e prospetivo. Foram recrutados doentes ambulatórios/hospitalizados de 01-03-2012 a 31-08-2012 e estudados tendo em conta a idade, gênero, etiologia, consumo alcoólico e gravidade da DHC definida pelo score Child-Turcotte-Pugh. A avaliação nutricional incluiu a utilização da avaliação global subjetiva, antropometria nomeadamente índice de massa corporal (IMC), perímetro braquial, circunferência muscular do braço, prega cutânea tricipital e dinamometria. Os doentes foram seguidos durante 2 anos e foi registada a respectiva sobrevida. RESULTADOS: Foram incluídos 130 doentes com DHC (80 homens) com idade 22-89 anos (média 60 anos). A maioria apresentava cirrose alcoólica (45%). Os doentes hospitalizados apresentaram doença hepática mais severa ( P <0,001) e pior estado nutricional, definido pelo IMC ( P =0,002), perímetro braquial ( P <0,001), circunferência muscular do braço ( P <0,001), prega cutânea tricipital ( P =0,07) e avaliação global subjetiva ( P <0,001). Um terço apresentava força de preensão manual deficiente/baixa. O consumo alcoólico ( P =0,03) e a desnutrição detetada pelo IMC ( P =0,03), perímetro braquial ( P =0,001), prega cutânea tricipital ( P =0,06), circunferência muscular do braço ( P =0,02) e avaliação global subjetiva ( P <0,001) encontraram-se associados à gravidade da DHC. Dos 25 doentes que faleceram durante o seguimento, 17 apresentavam desnutrição severa definida pela prega cutânea tricipital. A desnutrição definida pela prega cutânea tricipital revelou ser um fator preditivo de mortalidade ( P <0,001). CONCLUSÃO: A desnutrição calórico-proteica é comum na DHC para a qual o álcool desempenha um papel importante. A prega cutânea tricipital é o parâmetro antropométrico mais eficiente e encontra-se associado à mortalidade. A avaliação nutricional deve ser considerada mandatória na abordagem rotineira de doentes com DHC.

Short Stature Is Associated With Overweight but Not With High Energy Intake in Low-Income Quilombola Women.

BACKGROUND: Population exposed to chronic undernutrition in early life seems to be more susceptible to obesity in adulthood due to the development of mechanisms that improve the efficiency of energy use. Therefore, these individuals have relatively reduced energy requirements (thrifty phenotype). OBJECTIVE: To investigate, among women living on severe socioeconomic vulnerability, whether short stature, a marker for undernutrition in early life, is associated with excess body weight but not with a high energy intake. METHODS: This cross-sectional study, carried out between July and November 2008, evaluated 1308 women from all (N = 39) Quilombola communities of Alagoas. Adequacy of energy intake was estimated by the ratio between energetic ingestion and the estimated energy requirement (EER). RESULTS: The prevalence of short stature (≤ 154.8 cm) was 43.0% and 52.4% had excess body weight (body mass index ≥ 25 kg/m2), being that 33.1% were overweight and 19.3% obese. Excess body weight was higher among women with short stature (56.6% vs 49.2%; P = .008), even after adjusting for age, energy intake, and per capita income (prevalence ratio = 1.16; 95% confidence interval = 1.04; 1.28). The ratio of energy intake/EER was independent of women's stature. CONCLUSION: Excess body weight among Quilombola women represents a serious health problem. Short stature was significantly associated with excess body weight but not with a high energy intake. "Thrifty phenotype" may be one of the plausible explanations for this finding.

Introduction: Anastomotic leak is one of the main complications of patients submitted to gastrointestinal surgery. It occurs in approximately in 3.4% to 15% of cases. In Colombia the overall incidence of anastomotic leak is not known. Material and methods: A prospective cohort study that included patients undergoing anastamosis and who were followed up for up to 30 days. A descriptive analysis of the information was performed. The variables were analyzed with the chi-square test and the Kaplan-Meller graphs were used to determine the time to the event. Data analyses was performed on STATA 13. Results: 195 patients were admitted. 47.1% were male, and the median age of the study group was 60 years (ICR: 48-70). The incidence of anastomotic failure was 10.8% and the incidence rate was 10.2 per 1000 person-years; 29.7% of the patients presented postoperative complications and a mortality rate of 9.7%. The median hospital stay was 8 days (ICR: 5 - 16). Conclusion: The incidence of anastomotic leak observed appears in accordance with reports published in the world literature. The history of abdominal surgery as well as emergency surgery were the most frequent factors among the patients who developed anastomosis leak

Severe protein-calorie malnutrition in two brothers due to abuse by starvation / Desnutrição proteico-calórica grave em dois irmãos devido ao abuso por privação alimentar

Abstract Objective: To describe the case of two siblings with severe protein-calorie malnutrition due to abuse by starvation. Cases description: The two patients were simultaneously referred to the Hospital Municipal, where they were admitted to the Pediatric Gastroenterology clinic of a university hospital for diagnostic investigation of the cause of severe malnutrition and screening tests for Celiac Disease, Cystic Fibrosis and Environmental enteropathy among others. The exams were all normal, and after detailed research on the interactions of this family, we reached the conclusion that the malnutrition was due to abuse by starvation. The children spent approximately two months in the hospital, receiving a high-protein and high-calorie diet, with significant nutritional recovery. Comments: Abuse by starvation, although rare, should always be considered of as one of the causes of child malnutrition and pediatrician should be aware of the child's development, as well as the family interactions, to prevent more severe nutritional and emotional consequences in the future.

Resumo Objetivo: Descrever os casos de dois irmãos acometidos de desnutrição proteico-calórica grave causada por abuso por privação alimentar. Descrição dos caso: Os dois pacientes vieram simultaneamente encaminhados de hospital municipal, onde estavam internados, ao Ambulatório de Gastrenterologia Pediátrica de um hospital universitário para investigação diagnóstica da causa de desnutrição grave. Foram feitos exames para pesquisa de doença celíaca, fibrose cística e enteropatia ambiental, entre outras. Os exames mostraram-se todos normais e, após investigação detalhada sobre o relacionamento dessa família, chegou-se à conclusão de que a desnutrição tinha como causa o abuso por privação alimentar. As crianças passaram cerca de 2 meses internadas, receberam uma dieta hiperproteica e hipercalórica, com recuperação nutricional significativa. Comentários: O abuso por privação alimentar, embora raro, deve sempre ser pensado como uma das causas de desnutrição infantil, deve o pediatra estar atento ao desenvolvimento da criança, bem como ao seu relacionamento familiar, para evitar consequências nutricionais e emocionais mais graves no futuro.

Acidose metabólica e sua associação com o estado nutricional em hemodiálise / Metabolic acidosis and its association with nutritional status in hemodialysis

Resumo Introdução: A acidose metabólica é frequente em pacientes dialíticos e participa na patogênese da desnutrição energético-proteica destes pacientes. Objetivos: Avaliar a prevalência de acidose metabólica em hemodiálise e pesquisar sua associação com o estado nutricional. Métodos: Foi realizado um estudo transversal em pacientes em hemodiálise em um único centro. O estado nutricional foi avaliado por meio de indicadores antropométricos, bioquímicos e da bioimpedância elétrica multifrequencial. Acidose metabólica foi definida como bicarbonato sérico (BIC) < 22 mEq/L, e os pacientes foram divididos em 3 grupos, segundo o BIC (< 15,15-21,9 e ≥ 22). A associação entre o BIC e as variáveis contínuas foi pesquisada com o teste de Kruskal Wallis. A correlação linear entre o BIC e as variáveis do estudo também foi testada. Resultados: Foram avaliados 95 pacientes, 59% masculinos, idade média 52,3 anos. A prevalência de acidose metabólica foi 94,7%. O IMC, o ganho de peso interdialítico e o PTH foram significativamente diferentes entre os 3 grupos de BIC. O BIC apresentou correlação negativa significativa com ureia, fósforo e ganho de peso interdialítico. Não houve correlação significativa com albumina, ângulo de fase e índice de massa magra. Conclusão: A prevalência de acidose metabólica foi elevada na população em estudo, e um BIC mais baixo correlacionou-se com valores maiores de ureia, PTH, fósforo, ganho de peso interdialítico e menores de IMC. A avaliação do estado metabólico em hemodiálise deve ser implementada rotineiramente, considerando-se os efeitos negativos da acidose no estado nutricional, inflamatório e na doença óssea.

Abstract Introduction: Metabolic acidosis is a common problem in dialysis patients and plays an important role in the pathogenesis of protein-energy malnutrition in these patients. Objectives: To assess the prevalence of metabolic acidosis in hemodialysis and search their association with nutritional status. Methods: A cross-sectional study was performed in hemodialysis patients at a single center. Nutritional status was assessed by anthropometric, biochemical and multifrequency bioelectrical impedance analysis. Metabolic acidosis was defined as serum bicarbonate (BIC) < 22 mEq/L and patients were divided into 3 groups according to BIC (< 15.15 to 21.9 and ≥ 22). The association between BIC and continuous variables was investigated using the Kruskal Wallis test. The linear correlation between BIC and the variables of the study was also tested. Results: We studied 95 patients, 59% male, mean age 52.3 years. The prevalence of metabolic acidosis was 94.7%. BMI, interdialytic weight gain and PTH were significantly different among the 3 groups of BIC. The BIC was negatively correlated with urea, phosphorus and interdialytic weight gain. There was no significant correlation with albumin, phase angle and lean body mass index. Conclusion: The prevalence of metabolic acidosis was high in this population, and a lower BIC correlated with higher levels of urea, PTH, phosphorus, interdialytic weight gain and lower BMI. The evaluation of acid-basic status should be routinely implemented in dialysis patients by considering the negative effects of acidosis on the nutritional status, inflammation and bone disease.

NUTRITIONAL STATUS AND DIETARY INTAKE IN NON-CIRRHOTIC ADULT CHRONIC HEPATITIS C PATIENTS / Estado nutricional e ingestão dietética de adultos portadores de hepatite C crônica

BackgroundThe hepatitis C virus is one of the main causes of liver disease worldwide and may develop nutritional deficiencies.ObjectiveThe objective of this study was to assess and compare different nutritional status methods of adult patients with chronic hepatitis C virus, and to describe inadequacies in dietary intake.MethodsA cross-sectional study was conducted with adult outpatients with hepatitis C virus at a Brazilian hospital. Nutritional assessment included the 24-hour dietary recall, anthropometry (body weight, height, body mass index, triceps skinfold, mid-upper arm circumference, mid-arm muscle circumference, mid-upper arm muscle area, adductor policis muscle), Subjective Global Assessment, Royal Free Hospital Global Assessment and handgrip strength.ResultsA total of 94 outpatients (ages 30 to 76 years), was included, 46 were men. The prevalence of malnutrition as measured by the different methods was 6.4% (body mass index); 60.6% (handgrip strength), and 53.2% (Royal Free Hospital Global Assessment). There was correlation between mid-upper arm circumference and mid-arm muscle circumference (r=0.821), mid-upper arm circumference and triceps skinfold (r=0.575) and mid-upper arm circumference and mid-upper arm muscle area (r=0.781). Energy and protein intakes were below recommended levels in 49 (52.1%) and 44 (46.8%) of patients, respectively. Inadequate calcium, potassium, zinc and vitamin C intakes occurred in 92.6%, 97.9%, 63.8% and 60.6% of patients. There was an association between dietary energy and protein intake with Royal Free Hospital Global Assessment (P<0.001) and a tendency for them to be associated with handgrip strength (P=0.076 and P=0.054).ConclusionMalnutrition is frequently in hepatitis C virus patients. They have high prevalence of inadequate energy, protein and micronutrients intake, even in the absence of cirrhosis.

Houve associação significativa entre o consumo de energia e proteína com o Avaliação Subjetiva do Royal Free Hospital (P<0,001) e uma tendência de associação com a dinamometria (P=0,076 e P=0,054).ConclusãoDesnutrição é frequente em portadores crônicos de hepatite C. Pacientes com vírus da hepatite C têm alta prevalência de ingestão energética e proteica inadequada.

Influência da L-glutamina sobre aspectos imunomodulatórios de células tronco mesenquimais medulares em situação de desnutrição proteico-energética / The influence of L-glutamine on imunumodulatory aspects of bone marrow mesenchymal stem cells under protein-energy malnutrition

A desnutrição proteico-energética (DPE) altera a hemopoese e, portanto, a geração de células imunológicas, bem como compromete o sistema imune. Desta forma, indivíduos desnutridos apresentam maior susceptibilidade a infecções. As células tronco mesenquimais (CTMs) possuem propriedades imunomodulatórias e são importantes na formação do estroma medular que sustenta a hemopoese. Visto que a L-glutamina (GLUT) é o aminoácido condicionalmente essencial mais consumido por CTMs, e que também apresenta capacidade imunomoduladora, investigou-se, neste trabalho, se a GLUT exerceria efeito sobre aspectos imunomodulatórios das CTMs em um modelo experimental de DPE. Para tanto, utilizou-se camundongos da linhagem BALB/c, os quais receberam rações normoproteica ou hipoproteica isocalóricas contendo, respectivamente, 12% e 2% de proteína por um período de 5 semanas. Após o isolamento e a caracterização de CTMs provenientes dos grupos controle (CTMct) e desnutrido (CTMdesn), cultivou-se essas células em 0, 0,6, 2 e 10mM GLUT, a fim de determinar a influência deste aminoácido sobre a expressão de fatores de transcrição e produção de citocinas por CTMct e CTMdesn. Adicionalmente, avaliou-se o efeito dos sobrenadantes das culturas de CTMct e CTMdesn sobre a proliferação e produção de citocinas por macrófagos e linfócitos esplênicos. Os animais desnutridos apresentaram anemia, leucopenia, hipoplasia medular e diminuição na concentração de proteínas séricas, albumina e préa-lbumina. A DPE não modificou a morfologia e o fenótipo das CTMs, bem como não alterou a expressão de proteínas reguladoras do ciclo celular. Por outro lado, a expressão de NFkB e STAT-3 e a produção de IL-1ß, IL-6, IL-10 e TGF-ß por CTMs foram alteradas pela DPE e variaram de acordo com as concentrações de GLUT testadas. O aumento na concentração de GLUT diminuiu a expressão de NFkB e induziu a expressão de STAT-3 por CTMs obtidas de ambos os grupos. Quanto a produção de citocinas por essas células, observou-se uma diminuição nos níveis de IL-ß e IL-6 e uma elevação nos níveis de IL-10 e TGF-ß com o aumento na concentração de GLUT. Variações na concentração desse aminoácido não alteraram a produção de IL-17 ou IFN-γ por CTMct e CTMdesn. Ademais, a concentração de GLUT alterou, de forma diretamente proporcional, a taxa de proliferação das CTMs. Os meios condicionados de CTMct e CTMdesn diminuíram a proliferação de macrófagos e linfócitos esplênicos estimulados com LPS, induziram aumento na produção da citocina antiinflamatória IL-10 por ambos os tipos celulares e diminuíram a produção das citocinas pró-inflamatórias IL-12 e TNF-α por macrófagos e IL-17 por linfócitos. Portanto, conclui-se que a GLUT possui efeito sobre a proliferação das CTMs, bem como a capacidade de imunomodular estas células

Protein-energy malnutrition (PEM) alters hemopoiesis and, therefore, the generation of immune cells, and compromises the immune system. In this way, malnourished individuals are more susceptible to infections. Mesenchymal stem cells (MSCs) have immunomodulatory properties and are important in the formation of bone marrow stroma that supports hemopoiesis. Since L-glutamine (GLUT) is a conditionally essential amino acid, which is most consumed by MSCs, and present immunomodulatory capacity, this work investigated whether GLUT would have an effect on immunomodulatory aspects of MSCs in a PEM experimental model. For this purpose, BALB/c mice were used, which received isocaloric normoproteic or hypoproteic diets, containing respectively, 12% and 2% of protein for a period of 5 weeks. After isolation and characterization of MSCs from control (MSCct) and malnourished (MSCmaln) groups, these cells were cultured with 0, 0.6, 2 and GLUT 10mM in order to determine the influence of this amino acid on the expression of transcription factors and cytokine production by MSCct and MSCmaln. Besides that, the effect of MSCct and MSCmaln culture supernatants on proliferation and cytokine production by macrophages and splenic lymphocytes was evaluated. Malnourished animals presented anemia, leucopenia, marrow hypoplasia and decreased concentration of serum proteins, albumin and prealbumin. PEM did not change morphology and phenotype of MSCs or altered the expression of cell cycle regulatory proteins. On the other hand, the expression of NFkB and STAT-3 and the production of IL-1ß, IL-6, IL-10 and TGF-ß by MSCs were modified by PEM and varied according to the tested GLUT concentrations. An increase in GLUT concentration decreased NFkB expression and induced STAT-3 expression by MSCs obtained from both groups. Regarding the production of cytokines by these cells, an increase in GLUT concentration resulted in decreased IL-1ß and IL-6 levels and increased IL- 10 and TGF-ß levels. Changes in the concentration of this aminoacid did not alter IL- 17 or IFN-γ production by MSCct and MSCmaln. Furthermore, the concentration of GLUT changed, in direct proportion, the proliferation of MSCs. The conditioned media MSCct and MSCmaln decreased the proliferation of macrophages and splenic lymphocytes stimulated with LPS, induced an increase in the production of the antiinflammatory cytokine IL-10 by both cell types, and decreased the production of proinflammatory cytokines IL-12 and TNF-α by macrophages and IL-17 by lymphocytes. Therefore, it can be concluded that GLUT has an effect on the proliferation of MSCs and it has the capacity to immunomodulate these cells

Caracterización de niños de hasta 9 años con desnutrición proteicoenergética / Characterization of children up to 9 years with protein-energy malnutrition

Se realizó un estudio descriptivo, longitudinal y prospectivo de 32 niños de hasta 9 años con desnutrición proteicoenergética, atendidos en la consulta de nutrición del Policlínico Universitario "Josué País García" de Santiago de Cuba, desde junio del 2012 hasta mayo del 2013, con vistas a caracterizarles. Entre las variables analizadas sobresalieron: edad, sexo, tipo de lactancia, hábitos alimentarios, condiciones de hacinamiento y percápita económico.

Among the analyzed variables there were: age, sex, nursing type, alimentary habits, hacination conditions and economy per capita. The age group 1-3 years, the male sex, the mixed maternal nursing, the regular alimentary habits, the poor per capita economy and those affected exposed to hacination conditions prevailed in the series.

Principales enfermedades asociadas al estado nutricional en el niño menor de un año / Main diseases associated with nutritional status in children under one year of age

Introducción: la nutrición tiene una importancia trascendental durante el período prenatal y los primeros años de la vida, incluida su influencia sobre el crecimiento, el desarrollo físico y mental. La desnutrición proteico-energética favorece las infecciones, disminuye la resistencia a casi todas las enfermedades, actúa como causa coadyuvante de morbilidad y mortalidad infantiles y repercute sobre el desarrollo psíquico. Objetivo: conocer las principales enfermedades asociadas al estado nutricional en los ni ños menores de un año ingresados en el Hospital Pediátrico «José Luis Miranda¼ de la provincia de Villa Clara, desde enero de 1997 hasta diciembre de 2010. Métodos: Se seleccionaron 361 niños con el diagnóstico de desnutrición proteico-energética y 361 con el estado nutricional normal. Se evaluaron diversas variables: edad, causas por las que enfermaron e ingresaron, así como los ingresos en las salas de cuidados especiales. Resultados: en ambos grupos predominaron los ni ños menores de seis meses (66 %), las enfermedades diarreicas (74 %) y los ingresos por esta causa (78 %); el ingreso de forma directa a las unidades de terapia fue mayor en los niños desnutridos. Se produjeron ocho fallecimientos. Conclusiones: existió relación entre el estado nutricional, la función inmunitaria, la morbilidad y la mortalidad por enfermedades infecciosas, sobre todo por diarreas. Estos resultados permitirían diseñar estrategias de intervención con vistas a mejorar este indicador.

Introduction: nutrition is of great and important significance during prenatal period and the first years of life, because of its influence over children's growth, as well as, their physical and mental development. Protein-energy malnutrition in infants brings about some infections; reduces the resistance to almost all of the diseases, works as a cause of adjuvant morbidity and infant mortality, and affects their psychological development. Objective: to know about the main diseases associated with nutritional status in children under one year of age, who were admitted at "José Luis Miranda" Pediatric Hospital in Villa Clara province, from January, 1997 to December, 2010. Methods: a number of 361 children diagnosed with protein-energy malnutrition were selected, as well as, 361children with a normal nutritional state. Diverse variables were evaluated, such as, age, the causes of getting sick and being admitted to the hospital, and admissions to special care units. Results: in both groups predominated children under six months (66 %), bacterial diarrheal diseases (74 %) and admissions due to this cause (78 %); the admission to special care units was higher in malnourished children. Eight children died. Conclusions: there was a relationship among nutritional status, immunological function, morbidity and mortality due to infectious diseases, mainly because of diarrheas. These results will allow us to design intervention strategies in order to improve this indicator.
