RESUMO
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.

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.

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.

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.

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.
RESUMO
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.
RESUMO
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.

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.
