Avaliação da suplementação com vitamina E, na forma natural ou sintética, em mulheres no pós-parto imediato e sua concentração no colostro

The Vitamin E consists of eight chemically homologous forms, designated alpha, beta, gamma and delta tocopherols and tocotrienols. Biologically, the alpha-tocopherol (α-TOH) is the most important. Commercially, are found two types of α-TOH a natural (RRR-alpha-tocopherol) and another synthetic (all-rac-alpha-tocopherol). Both forms are absorbed in the intestine, the liver is a preference in favor of forms 2R, due to transfer protein α-TOH. It has higher affinity to these stereoisomers. Newborns are considered high risk for vitamin E deficiency, mainly premature, these have breast milk as a food source for maintenance of serum α-TOH. Clinical signs such as thrombocytosis, hemolytic anemia, retrolental fibroplasia, intraventricular hemorrhage, bronchopulmonary dysplasia and spinocerebellar degeneration can be found in case of a low intake of α-TOH. Thus, maternal supplementation on postpartum with α-TOH can be an efficient way to increase levels of vitamin E in breast milk and thus the consequently increase the supply of micronutrient for the newborn. However, most studies with vitamin E supplementation have been conducted in animals and little is known about the effect of maternal supplementation in humans, as well as on its efficiency to increase levels of α-TOH in human milk, depending on the shape natural or synthetic. The study included 109 women, divided into three groups: control without supplementation (GC) (n=36), supplemented with natural capsule (GNAT) (n=40) and the synthetic capsule (GSINT) (n=33). Blood samples were collected for determination of maternal nutritional status, and colostrums at initial contact and after 24 hours post-supplementation. Analyses were performed by High Performance Liquid Chromatography. Values of α-TOH in serum below 499.6mg/dL were considered deficient. We used the Kruskal-Wallis test and Tukey test to confirm the increase of alpha-tocopherol in milk and efficiency of administered capsules. Daily consumption of α-TOH was based on daily intake of 500 mL of colostrum by the newborn and compared with the nutritional requirement for children from 0 to 6 months of age, 4 mg / day. The mothers had mean concentration of serum α-TOH in 1016 ± 52, 1236 ± 51 and 1083 ± 61 mg / dL, in CG, GNAT and GSINT respectively. There were no women with deficiiency. The GC did not change the concentrations of α-TOH in colostrum. While women supplemented with natural and synthetic forms increased concentrations of α-TOH colostrum in 57.6% and 39%, respectively. By comparing supplemented groups, it was observed a significant difference (p=0.04), the natural capsule more efficient than the synthetic, approximately 49.6%. Individually, 21.1% of the women provided below 4mg/day of α-TOH, after supplementation for this index declined4.1%. Thus, maternal supplementation postpartum raised the levels of alpha-tocopherol in colostrum, and increased efficiency was observed with the natural form

Alimentación y desarrollo infantil I: el estado nutritivo de los niños en edad escolar de un suburbio madrileño (Rev Clin Esp 1944; XII:87-94)

El estudio clínico del estado nutritivo de un grupo de niños en edad escolar, habitantes de un suburbio madrileño revela la existencia, relativamente rara, de signos carenciales específicos, que contrasta vivamente con el considerable retraso que se observa en su desarrollo somático. Los hechos parecen demostrar que el problema nutritivo de estos niños es sobre todo un problema cuantitativo. El retraso de la evolución está en relación con la insuficiencia global de la dieta y con el déficit de calcio que es probablemente el elemento individual con mayor grado de carencia en las dietas. La anemia que presenta el 98% de los niños no parece deberse únicamente a una deficiencia de hierro porque la dieta parece tener una cantidad adecuada; probablemente esté más en relación con el exiguo contenido de proteínas animales de la ración.

Acute hemorrhagic necrotizing pancreatitis in falciparum malaria

Malaria is a pathology caused by a parasite called Plasmodium, characteristic of tropical countries. The most frequent symptomatology includes cerebral malaria, jaundice, convulsive crisis, anemia, hypoglycemia, kidney failure and metabolic acidosis, among others. We are presenting the case of a patient diagnosed with malaria who suffered from acute hemorrhagic necrotizing pancreatitis and evolved poorly, as an example of this combination of symptoms, rarely found in our country.

Endoscopy as a diagnostic and therapeutic alternative technique of taeniasis

Despite a low incidence in developed countries, gastrointestinal taeniasis should be suspected in patients with abdominal pain, diarrhea, anemia, and/or malabsorption of unknown origin, even more so if they come from endemic regions or areas with poor hygienic and alimentary habits. Diagnosis is traditionally reached by identifying the parasite in stools, but more recently both serological and immunological approaches are also available. Based on a patient diagnosed by gastroscopy, a literature review was undertaken of patients diagnosed by endoscopy. We discuss endoscopy as diagnostic modality, and the effectiveness and safety that endoscopic treatment may provide in view of the potential risk for neurocysticercosis.

Pesquisas genéticas, prognósticos morais e discriminação genética : um estudo de caso sobre traço falciforme

O debate sobre ética em pesquisa pode ser aplicado tanto ao âmbito da metodologia científica como a outras áreas do saber, como é o caso dos esportes. No campo da saúde esportiva brasileira, têm sido comuns pesquisas que fazem testes genéticos para identificar atletas com traço falciforme. Apesar da persistência de confederações esportivas brasileiras em discriminar atletas com essa característica hereditária, o traço falciforme não é uma doença. Este artigo relata o caso de uma atleta de futebol vítima de discriminação genética: identificada com o traço falciforme, ela foi considerada inapta a participar de um campeonato pela Confederação Brasileira de Futebol. O artigo analisa as repercussões da pesquisa genética para identificação do traço falciforme na ausência de cuidados éticos voltados à preservação dos direitos de quem se submete aos testes. Além disso, mostra a situação de vulnerabilidade à qual estão expostas pessoas envolvidas em pesquisas que fazem testes genéticos sem cuidados éticos ou mesmo justificativas razoáveis e cujos resultados são interpretados sob a racionalidade do determinismo biológico e do reducionismo genético. As confederações esportivas brasileiras interessadas em identificar atletas com o traço falciforme deveriam submeter esse objetivo de estudo à avaliação de Comitês de Ética em Pesquisa, pois esse é um procedimento com potencial de acarretar prejuízos aos atletas. O teste genético não pode ser considerado um ato de assistência em saúde, visto que não há doença a ser tratada. _______________________________________________________________________________ ABSTRACT

Evaluation of Neurodevelopment and Factors Affecting it in Children With Acyanotic Congenital Cardiac Disease

Background: The rate of congenital heart disease is 0.8% in all live births. The majority of this, however, is acyanotic congenital heart disease. The survival rate of children with cardiac disease has increased with the developments provided in recent years and their lifetime is extended. Objectives: This study aims to evaluate neurodevelopment of children with uncomplicated acyanotic congenital heart disease in preschool period and determine the factors affecting their neurodevelopmental process. Patients and Methods: 132 children with acyanotic congenital heart disease aged 6 - 72 months were involved in the study. Mental development and intelligence levels of patients under 2 years old were assessed by using Bayley Development Scale-III, and Stanford Binet Intelligence test was employed for patients over 2 years old. Denver Developmental Screening Test II was applied to all patients for their personal-social, fine motor, gross motor and language development. Results: The average age of patients (67 girls, 65 boys) included in the study was 35.2 ± 19.6 months. It was determined that there were subnormal mental level in 13 (10%) patients and at least one specific developmental disorder in 33 (25%) patients. Bayley Mental Development Scale score of patients who had received incubator care in perinatal period was found significantly low (88 ± 4.2) compared to those with no incubator care (93.17 ± 8.5) (P = 0.028). Low educational level of father was established to be linked with low mental development scores at the age of 2 and following that age (P < 0.05). Iron deficiency anemia was discovered to be related to low psychometric test scores at every age (P < 0.05). Conclusions: Neurodevelopmental problems in children with acyanotic congenital heart disease were found higher compared to those in society. Mental development and intelligence levels of patients were determined to be closely associated with receiving incubator care, father’s educational level and iron deficiency anemia.

Las especies patógenas observadas son: Entamoeba histolytica 85%, Giardia lamblia 3,8%, Trichomona intestinalis 1,3% y Taenia saginata 2,5%.Según las características socioeconómicas, el 100% de la población consume agua potable. El 83% se lavan las manos antes de comer, el 71% lava las frutas antes de consumirlas, el 100% utiliza el servicio sanitario, a su vez el 42% presentan dolor abdominal, el 12% presentan diarrea, el 14% tiene prurito anal y el 46% tiene falta de apetito. Conclusiones: Los hábitos de higiene personal y de alimentación no se están llevando de la forma correcta por ello existe un porcentaje alto de parasitismo, por más que se cuente con los servicios básicos, esto no garantiza un parasitismo negativo

Alimentos fortificados con hierro en niños entre 6 a 23 meses del Hospital Vicente Corral Moscoso en la ciudad de Cuenca-Ecuador 2015

ANTECEDENTES: Los niños de 6 a 23 meses son vulnerables a déficit por micronutrientes por esto la OMS recomienda la fortificación con hierro. En Ecuador el 62% de niños de 6 a 11 meses y el 32,4% de niños de 12 a 23 meses, presentan anemia por déficit de hierro OBJETIVO GENERAL: Describir la fortificación con hierro de los alimentos de los niños y niñas de 6 a 23 meses de edad, en su hogares, previo a su ingreso en el Hospital Vicente Corral Moscoso en un periodo de 5 meses en el año 2015 METODOLOGÍA: Estudio descriptivo en 171 niños de 6 a 23 meses ingresados en el Hospital Vicente Corral Moscoso de Cuenca en el 2015. Se recolectaron los datos demográficos acerca de la alimentación fortificada con hierro. RESULTADOS: El 50,8% de los niños estuvieron entre 6 y 12 meses de edad, el 64,1% tuvo estado nutricional normal, el 42,1% fueron hospitalizados por neumonía, el 58,5% viven en zonas urbanas, el 53,85% tiene familias nucleares, el 56,1% con nivel de instrucción básica, el 64,3% de las cuidadoras se dedicaba a quehaceres domésticos. El 52% de niños recibió alimentos fortificados con hierro. Podemos decir que no se encontró relación estadística entre la ingesta de alimentos fortificados y las variables demográficas. CONCLUSIONES: El porcentaje de niños que reciben alimentos fortificados con hierro fue del 52%, por lo tanto es importante promover la ingesta de alimentos fortificados con hierro, para obtener un crecimiento y desarrollo óptimo en los niños
