Full textThe more common and mild deficiency observed in the general healthy population is probably due in part to insufficient dietary intake of folate. Folate deficiency has been associated with increased risk for colon cancer. In a pilot study presented here, the impact of altered folate intake on tumor multiplicity in the Min mouse, a model for multiple intestinal neoplasia, was assessed. Folate deficient diets did not produce a consistent change in tumor numbers. However, a linear correlation between S-adenosylmethionine and S-adenosylhomocysteine content of preneoplastic tissue and tumor multiplicity was identified.
This thesis contributes to our understanding of the impact of genetic- and/or dietary-induced folate deficiency on cellular and organismal functions.

Full textThe present study seeks to use an animal model to examine how dietary restriction, physiological and non-physiological needs, and nicotine administration influence eating behavior. Diets restricting proteins were fed to rats in order to assess if any abnormalities in feeding behavior result. Following a plan of limited access to the restricted nutrient a physiological rebound occurred, involving increased selection for the restricted nutrient. Non-physiological needs were also be studied by observing the effect of taste modification on the eating behavior. The taste of the restricted nutrient was modified to have a preferred, sweet taste or non-preferred, bitter taste. Non-physiological drives to avoid unpleasant tastes were overridden by the physiological need for the restricted nutrient. Furthermore, the drive to increase consumption of a pleasant tasting food was seen only in protein deficient rats, whereas rats that were not deficient in protein ate as much of the sweet tasting food as the unadultered food. Nicotine administration was seen to suppress the physiological need for the deficient nutrient, and withdrawal of nicotine resulted in a return to the normal physiological drive for the restricted nutrient

Treatments were applied to cultivars Oak Leaf Red Pixie (crisp group without head, reddish leaves), Lucy Brown (American group, smooth, green leaves) and Veronica (crisp group without head, green leaves). Treatments with the omission of Ca, P and S in nutrient solution were applied on the same day that the lettuce seedlings were transplanted from nursery to the channels of final growth. After four days, it were applied the solutions with the omission of N, K and Mg. Visual symptoms of deficiency under the experimental conditions appeared to occur in the following order: N, K, Mg, P and Ca. The omission of S did not show the visual symptoms of nutrient deficiency. Among the cultivars, the symptoms of nutritional deficiency were easily observed in 'Veronica' and 'Lucy Brown' and hardly identified in the 'Red Oak Leaf Pixie

Full textParasitic infection did, however, affect the host nutritional status. Spleen weight was significantly higher in infected mice in both experiments. In the challenge infection, both liver and spleen copper concentrations were significantly higher, and spleen iron concentration significantly lower in the infected mice. That these significant results were seen only in the challenge infection may suggest the role of the host immune response.

Full textFolate deficiency can lower brain SAM levels and cause depression. Thus, methionine, which raises brain SAM, may overcome the effects of folate deficiency. Seven day food records were done by 26 psychiatric outpatients who were stable on lithium treatment. Eight patients had mean daily folate intakes below those recommended. Some of those with low folate intake had high methionine intake consistent with the idea that methionine could substitute metabolically for folate deficiency. Daily methionine intakes ranged from 13 to 304% of the recommended intake. As methionine had behavioral effects in the rat at doses much less than the daily dietary intake this raises the question of whether varying daily intakes of methionine in humans have behavioral implications.

Full textAmong PS mice, a challenge dose of 200 L3 caused more active worm expulsion than infection with 100 L3. Both serum monocyte chemotactic protein-5 and gut fluid leakage were positively correlated with worm expulsion whereas numbers of mucosal mast cells, eosinophils, goblet cells and Paneth cells were unaffected by doses. Among PD mice, worm survival was prolonged and no dose-dependent worm expulsion was observed. In addition, a wide range of Th1 inflammatory cytokines including leptin was elevated in infected PD mice suggesting (1) that PD mice are unable to mount the appropriate Th2 inflammation and (2) that infection in PD mice induces a Th1 inflammation that allows continuing persistence of the parasite.
The shift to Th1 inflammatory responses in PD mice may also explain modifications in mineral distributions in tissues. Despite adequate dietary intakes of minerals in both PD and PS mice, serum iron concentrations were lower after H. bakeri challenge infection. Infection also reduced calcium and iron concentrations as well as the Ca/Zn ratio in the spleen. In contrast, PD resulted in increased iron and calcium concentrations as well as increased Ca/Zn ratio in the spleen and Fe/Zn ratio in the liver, but reduced calcium, zinc, copper and sulfur concentrations, and the Cu/Zn ratio in the liver.
Re-feeding PD mice with a PS diet restored parasite expulsion, regardless of whether the PS diet was provided during the primary or challenge infection. Thus, although PD mice have suppressed Th2 responses and elevated Th1 inflammation, their response to the primary infection is sufficient to ensure that parasite expulsion occurs once protein status is restored.
Together, these studies show that the shift toward Th1 inflammation plays a key role in prolonged parasite survival and mineral redistribution in protein deficient, infected mice.

Full textPrimary immunodeficiencies (PID) include a heterogeneous group of diseases with immunological system disturbance, increasing susceptibility to infections. The therapeutic advances have increased life span of these patients, as well as the nutritional needs. The aim of this study was to compare the nutritional status of patients from different immunodeficiency groups evaluated by the following Z scores means: weight for age, height for age, body mass index (BMI) for age and the percentiles distribution of upper arm muscle circumference (UAMC) and triceps skin fold thickness (TSF) for age. Laboratorial exams related to nutritional status were also carried out. Among patients from Allergy and Immunology Unit from ICr-HCFMUSP, 72 patients with definitive or probable diagnosis were evaluated, with age from 3 to 19 years allocated in 3 PID groups: humoral (n=44), phagocytes (n=12) and cellular or combined (n=19). These three groups were described through age, gender, weight and height. Through these data, were determined the weight for age, height for age, and BMI for age Z scores. There were calculated for each Z score: the mean, standard-deviation and confidence interval 95%, being the obtained means compared by ANOVA and after, the Tukey-Kramer post hoc test. There were evaluated for intake food: a 24-hour recall and a food frequency questionnaire. It was observed that the cellular or combined and phagocyte groups presented lower height for age and BMI for age Z score means than the humoral group. The weight for age Z score means didnt show significant statistical difference, however the humoral group had the highest mean. Among the subgroups from humoral group was not found significant statistical difference. The UAMC was below the 15th percentile mean in 25% of the humoral group, 55.5% from the phagocyte group and 68.4% from the cellular or combined group. About TSF, 18.1% of patients from humoral group, 11% from phagocyte group and 36.8% from the cellular or combined group were below 15th percentile. The protein intake exceeded the RDA in 77%, 100% and 84.2% in patients from humoral, phagocyte and cellular or combined groups, respectively. The humoral, phagocyte and cellular or combined groups presented high cholesterol levels. In conclusion, it was observed more severe nutritional impairment in cellular or combined and phagocyte PID than the humoral group. The high cholesterol level and the UAMC reduction may suggest a metabolic disturbance related to chronic inflammation in PID patients, with risk for cardiovascular chronic disease in the future.

Full textENGLISH ABSTRACT: Pregnancy and growth have been found to have a detrimental effect on the micronutrient status of adolescent girls. Dietary studies in adolescents have shown serious shortfalls in their dietary iron and folate intake. The competition for nutrients between the fetus and a pregnant adolescent may carry the risk of complications such as intrauterine growth retardation, pre-eclampsia, both maternal and fetal intrapartum mortality, the increased risk of birth injuries and low birth weight. The aim of the study was to assess the nutritional status of rural black, pregnant teenagers attending the antenatal clinic at Siloam Hospital in the Limpopo Province, with special emphasis on iron and folic acid intake, and evaluation of the newborn babies in terms of weight status and neural tube defects. The nutritional status was determined in 40 pregnant and 40 non-pregnant adolescent girls. The pregnant girls were selected during their first visit to the antenatal clinic, and the non-pregnant girls were selected from nearby schools. The demographic and dietary history questionnaires were used to collect information from the subjects. The dietary intake of the subjects was collected by the completion of a pre-tested quantified food frequency questionnaire. The anthropometric questionnaire was used to get information from the pregnant adolescents and the control group. The infant anthropometric measurements questionnaire provided information on the infant and the outcome of birth. Blood was collected from the pregnant adolescent girls and the control subjects. Anaemia was observed in 57.5% of the pregnant and 27.5% of the non-pregnant adolescents (haemoglobin

Full textIron deficiency anemia is currently the most prevalent nutritional problem in the world. Its incidence is more significant in developing countries, where 36 per cent of the population develops this pathology. A substancial part of Brazilian population is affected by it. Even in the State of São Paulo the situation is the same: 35 per cent o f the children aged six to sixty months had iron deficiency anemia in the 80\'s in the city of São Paulo; and in Osasco, a town in the metropolitan area of São Paulo, 51 per cent of the school children aged 7-8 are anemic. Aiming at assessing the role of the diet as one of the determining causes for the anemia which is prevalent among teenagers in the town of Osasco, State of São Paulo, Brazil, a study was carried out with 509 students from 5th and 8th grade in the public school network in Osasco. The prevelence of anemia was checked through blood hemoglobin sampling, using digital puncture and the cyanomethahemoglobin method. The results have shown a discrete 5,3 per cent , regardless the sex o f the students. The nutritional profile, identified through anthropometric measurement, indicated that 17,3 per cent of the teenagers were under percentil 10 for weight/age and 4,7 per cent under percentile 3. The proportion of undernourished youngsters was higher among students in 5th grade. Boys showed worse nourishment conditions than girls. The nutritional practice, known through the records of the teenagers\' food intake during three alternating days, proved similar to that of 1974/75, in São Paulo. It was noted that the intake of foods containing Vitamin C is low - Viatmin C being an important element for the absortion of iron - and there is a trend of replacing the traditional dinner by a light meal. Most teenagers\' energy intake is adequa te whereas iron\'s is inadequate. The teenagers\' diet may be considered good, thus explaining the discrete prevalence of anemia among this group. Nevertheless, the low density of iron and bioavaiable iron in the diet are indications of the probable substantial proportion of iron deficient teenagers among the population.

Full textChildren infected by HIV/Aids present malnutrition and nutritional deficiency, as anaemia by iron deficiency and hypovitaminosis A, causing damage to growing and developmente. The food fortification is seen as promising strategy to the combat of nutritional deficiency. Objective: Developing and testing the efficiency of a corn snack and bovine lung. rich in iron and vitamin, in the reduction of de anaemia and hypovitaminosis A, in children with HIV/Aids. Metodology: At first, a transversal study was carried out to characterize the nutritional state and hematology alterations - anaemia and dyslipidemia, in 63 children, with age between 5-10 years old, with HIV/Aids from the Unit of Infectology from Children Institute. At the same time, the snack rich and vitamin A, was developed through the thermoplastic extrusion, using as raw material: corn grits ingeminated and bovine lung lyophilized no fat (m/m, 90:10), as source of heme iron, in highly bioavailability. In the fragrance, bacon, onion and parsley and strawberry flavors, it was used fat substitute and retinol acetate to fortification. The acceptance of the snack, through sensorial evaluation with hedonic facial scale, had been done by 53 healthy children and infected by HIV/Aids, with ages between 2-10 years old, in the Civil Anima Association, SP. Finally, the nutritional intervention was done during 2 months; it was offered 3 portions of 30g/week of strenghtened snack to 18 children with HIV/Aids, with ages between 5-10 years old. To nutritional evaluation, it was followed: food consumption through the 24-hour diary, weight, height, hemoglobin, total iron, ferreting e serum retinol, at the beginning and in the ending of the intervention. Results: The slight, moderate or severe malnutrition was found in 46% of the cases; being the most frequency when considered, the z-score of height-for-age 39,7% of malnutrited, reflecting commitment of long duration (stunting) in the growing of these children. The prevalence of anaemia was 19%, end more of 66% between the AZT treated; there was association between anaemia the AZT use (zidovudina) in the anti retroviral therapy (ARVT) (p=0,022). The prevalence of hypercholesterolemia e hypertrigliceridemia, considering low values and increased, were respctively 53,5 and 51,7%; with tendency to major frequencies in the groups with protease inhibitors (PI) in ARVT. The strengthened snack developed, per each 100g, guaranteed 5,07 mg of iron and 780 µg RE of A vitamin, representing respectively 56% and even 78% of DRIS to children with age between 7-10 years old. The result of sensorial evaluation, showed around 80% of acceptance to all tested flavors. The nutritional intervention, resulted in growth of the hemoglobin average of 12,45 +/- 1,34 g/dL to 12,56 +/- 1,33 g/dL, without statistics significance; and increasing of serum retinol of 0,447 +/- 0,124 to 0,928 +/- 0,415 (p«0,01). Conclusion: Besides the studies of prevalence of nutritional deficiency in vulnerable groups, such as children with HIV/Aids, the nutritional intervention are relevant, because contribute as co-positive factors in the didease treatments, through the improvement of the nutrition state of the individual.

O enxofre (S) ? um nutriente essencial para crescimento e metabolismo das plantas, e sua defici?ncia pode limitar a produtividade de muitas culturas. A adapta??o de t?cnicas espec?ficas de an?lise espectral para a determina??o do estresse nutricional causado por este nutriente pode permitir a detec??o precoce da sua defici?ncia e suplementa??o de precis?o na aduba??o corretiva das plantas. Esse experimento foi conduzido com o objetivo de determinar se a reflect?ncia foliar obtida atrav?s do mini espectr?metro pode ser utilizada para detectar a defici?ncia de S em mudas de Eucalyptus urophylla. Durante 90 dias as mudas foram cultivadas em solu??o nutritiva de Clark modificada completa (sem omiss?o de S) e com omiss?o de S. Os sintomas visuais de defici?ncia de S foram observados e fotografados semanalmente. A cada 15 dias foram avaliados altura e di?metro das plantas e leituras nas folhas diagn?sticos, com o mini espectr?metro. Ao final de cada avalia??o, amostras de folhas diagn?sticos foram preparadas e submetidas ?s an?lises qu?micas do material vegetal dos teores de nutrientes, posteriormente as mudas foram separadas em ra?zes, caule e folhas para obten??o da massa seca total e dos seus componentes. Ap?s calcular a primeira derivada das reflect?ncias obtidas nas leituras com o mini espectr?metro, obteve-se a posi??o dos pontos de inflex?o. Foi realizado ainda um estudo de regress?o linear m?ltipla entre os teores de nutrientes das folhas diagn?sticos como vari?veis dependentes, e a produ??o de massa seca da parte a?rea e valores obtidos para o IPP como vari?veis independentes. A defici?ncia de S causou altera??es nas propriedades morfol?gicas e fisiol?gicas das plantas de Eucalyptus, o que refletiu nas mudan?as das propriedades espectrais foliares da esp?cie em quest?o. Os sintomas visuais de defici?ncia de S iniciaram-se aos 28 dias ap?s a aplica??o dos tratamentos (DAT), intensificando-se ao longo do experimento. Foi observado clorose nas folhas novas, caule mais delgado e redu??o no crescimento das mudas quando comparados ao tratamento completo. A an?lise nutricional detectou redu??o nas concentra??es de S foliar e defici?ncia do nutriente nas plantas aos 45 DAT. Contudo, somente aos 75 dias a defici?ncia de S alterou a reflect?ncia das mudas com omiss?o de S, deslocando o ponto de inflex?o para comprimentos de ondas mais curtos (? 700 ?m), ou seja, quando o aparelho (mini espectr?metro) conseguiu detectar defici?ncia nutricional de S nas plantas de Eucalyptus. A defici?ncia de S tamb?m reduziu a altura, di?metro e produ??o de massa seca total e dos seus componentes aos 75 DAT. A posi??o do ponto de inflex?o e a massa seca da parte a?rea apresentaram alta correla??o com a concentra??o de S foliar. As an?lises de regress?o linear m?ltipla e de correla??o simples indicaram que os valores de reflect?ncia foliar estimados pelo mini espectr?metro e pela massa seca da parte a?rea estavam estreitamente correlacionados com as concentra??es de S nas folhas das mudas de Eucalyptus (r2=0,99). Os resultados obtidos sugerem que a reflect?ncia espectral demonstra alto potencial como ferramenta diagn?stico para estimar a concentra??o de S foliar em Eucalyptus por meio do mini espectr?metro.

Sulfur (S) is an essential nutrient for plant growth and metabolism, its deficiency can limit the productivity of many crops. The adaptation of specific remote sensing and spectral analysis techniques for the determination of nutrient stress in plants could allow early detection and precise supplementation for corrective fertilization. This experiment was conducted with the objective of determining if the leaf reflectance obtained through the mini spectrometer can be used to detect S deficiency in Eucalyptus urophylla seedlings. During 90 days the seedlings were grown in complete nutrient solution of Clark (without omission of S) and with omission of S. The visual symptoms of S deficiency were observed and photographed weekly. Every 15 days, plants height and diameter were evaluated, and readings on the diagnostic leaf were taken with the mini spectrometer. At the end of each evaluation the samples of the diagnostic leaves were prepared and submitted to the chemical analyzes of nutrient contents of the plant material, later the seedlings were separated into roots, stem and leaves to obtain the mass of total dry matter and its components. After calculating the first derivative of the reflectances obtained in the readings with the mini-spectrometer, the position of the inflection points was obtained. A multiple linear regression study was carried out between the nutrient contents of the diagnostic leaves as dependent variables and the shoot dry matter yield and values obtained for the position of the inflection points as independent variables. Sulfur deficiency caused changes in the morphological and physiological properties of Eucalyptus plants, which reflected changes in the leaf spectral properties of the species. The visual symptoms of S deficiency began at 28 days after application of the treatments, intensifying throughout the experiment. It was observed chlorosis in the new leaves, slender stem and reduction in the growth of the seedlings when compared to the complete treatment. Nutritional analysis detected a reduction in the foliar S concentrations and nutrient deficiency in plants at 45 days after application of the treatments. However, only at 75 days S deficiency altered the reflectance of the seedlings under S omission, shifting the inflection point to shorter wavelengths (? 700 ?m),that is, when the device (mini spectrometer) was able to detect nutritional deficiency of S in Eucalyptus plants. Sulfur deficiency also reduced the height, diameter and yield of total dry mass and its components at 75 days after application of the treatments. The position of the inflection point and the shoot dry mass presented a high correlation with the concentration of leaf sulfur. Multiple linear regression and simple correlation analyzes indicated that leaf reflectance values estimated by the mini spectrometer and through MSPA were closely correlated with the concentrations of S in the leaves of the Eucalyptus seedlings (r2 = 0.99).The results obtained suggest that the spectral reflectance demonstrates high potential as a diagnostic tool to estimate the leaf sulfur concentration in Eucalyptus using the mini-spectrometer.

Full textEvery individual is born with a genetic potential for growth, which may or not be attained, depending on their living conditions. It could be said that growth is influenced by intrinsic (genetic and metabolic) and extrinsic factors (environmental factors such as diet, health, hygiene, housing and access to health services). Outstanding among the nutritional factors are vitamin and oligoelement deficiencies which may be associated with malnutrition or depend on insufficient absorption. Since calcium is the one of main mineral bone tissue component, we suggest that this is the main nutrient for adequate bone formation and, considering that vitamin D plays an important role in calcium metabolism, a diet with an insufficient amount of these nutrients can influence the formation of the skeleton. This review of the literature aims to emphasize the nutritional importance of calcium and vitamin D in the growth and development process, helping health care professionals update the recommendations and dietary sources of both nutrients. Thus, in children and adolescents, the low intake or low absorption of calcium and vitamin D may limit their stature development, and it will be necessary to supply sufficient amounts of both during the critical growth phase.

Full textWith the purpose of determining the dose, the more reccomended source and the application form of boron in eucalyptus forests with higher and lower initial growth, a field experiment was carried out at \'Siderúrgica Alterosa\', starting in May 2006, in \'Morada Nova de Minas\', State of Minas Gerais, Brazil. Ten treatments were tested in two genetic materials and two levels of fertilization, totalizing 40 treatments. According to the results, we concluded that (a) in relation to dose; the boron deficiency symptoms are minimized with doses superior to 8 kg.ha-1, however, in relation to volumetric increment, there was response only untill the dose of 7 kg.ha-1; (b) in relation to source; for each dose, the boric acid showed good performance regardless of clone or level of fertilization; and (c) in relation to application; the combined form by soil and foliar spraying was the only way to prevent the drying of the pointer of the trees during the water deficit, and the located application without spraying presented worst result when compared to application in total area.

Iron deficiency is considered the main cause of the nutritionais anemias, which affects approximately 0,5 billion people around the world, mainly in developing countries. The lack of studies on iron deficiency anemia and nutritional status in leprosy and the importance of this information before the treatment with drugs with hemolytic potential, was the reason for this study. After the approval of the Committee of Ethics in Research, eighty two patients paucibacillary and multibacillary leprosy clinical vials, new cases and without treatment were studied. To verify the status of iron in their bodies, biochemical, dietary and evaluation of the status nutritional parameters were used. Nine patients (11%) presented hemoglobin concentration below normal level and four of them (4,9%) iron deficiency anemia accordcing to the sex and the age. The nutritional evaluation for BMI revealed that 46,3% were classified as eutrophic, of 53,7% with dystrolphic BMI 48,8% presented overweight and obesity. The dietary evaluation demonstrated that the appropriate energy consumption reached 15,9 %, the diet being normoprotein, normoglycidic and normolipidic kind. Women presented smaller indexes of iron ingestion, mainly those whose age ranged from 18 to 50 years. The results showed a little occurrence of iron deficiency anemia, probably due to the consumption of foods with iron bioavailability.
A deficiência de ferro é considerada como a principal responsável pelas anemias nutricionais, afetando aproximadamente 0,5 bilhão de pessoas no mundo, principalmente em países em desenvolvimento. A escassez de estudos sobre anemia ferropênica e estado nutricional em hansenianos e a importância dessas informações antes do tratamento com drogas com potencial hemolítico, levaram a realização deste estudo. Após aprovação do Comitê de Ética em Pesquisa, estudaram-se oitenta e dois pacientes com hanseníase das formas clínicas paucibacilar e multibacilar, casos novos e sem tratamento. Para verificar o status de ferro no organismo utilizaram-se parâmetros bioquímicos, dietéticos e avaliação do estado nutricional. Nove pacientes (11%) apresentaram concentração de hemoglobina abaixo de ponto de corte e quatro deles (4,9%) anemia ferropênica segundo sexo e idade. A avaliação nutricional pelo IMC revelou que 46,3% foram classificados como eutróficos. Dos 53,7% com IMC distrófico, 48,8% apresentaram sobrepeso e obesidade. A avaliação dietética demonstrou que o consumo adequado de energia atingiu 15,9 %, sendo a dieta da maioria normoproteica, normoglicídica e normolipídica. As mulheres apresentaram menor índice de ingestão de ferro, principalmente no estágio de vida de 18 a 50 anos. Os resultados demonstram pouca ocorrência de anemia ferropênica, provavelmente decorrente do consumo de alimentos fontes de ferro biodisponível.

Full textInadequate intake of dietary iron can cause structural changes in the Central Nervous System (CNS) and, thus, in the optic nerve with impaired myelination process. These changes generated by postnatal iron deficiency anemia are not satisfactorily reversed after replacement iron. The tactile stimulation and environmental enrichment can reduce and/or prevent the damaging effects of malnutrition on the CNS. The objective of this study was to evaluate structural and quantitatively the optic nerve of Wistar rats with iron deficiency anaemia submitted to tactile stimulation and nutritional recovery. We used 4 groups: Control (C), Anemic (A), Recovered Not Stimulated (RN) and Recovered Stimulated (R), randomly composed of 1 adult female rat and 6 male newborns. These groups were divided according to the variable diet provided, the amount of iron/kg in the diet (with appropriate levels of iron (C), deficient in iron (A) and with recovery of the appropriate level of iron (R)). The Control (C) group was fed with ration containing 35 mg iron/kg diet and the Anemic (A) group, with 4 mg iron/kg diet, and the Recovered groups (RN and RE) with 4 mg iron/kg diet from day 0 to day 21, and 35 mg iron/kg from day 22. The Recovered groups were classified according variable stimulation: Stimulated (E), group submitted to tactile stimulation from day 0 to day 32, and Not Stimulated (N). During the breastfeeding period, the mother rats fed the diet given to each group, and after lactation period the puppies received the same diets of their mothers. At day 21, the female rats were euthanized and at day 32 all juveniles were anesthetized and perfused transcardially with a buffered saline solution (PBS) 0,05M, pH 7,3, having their optic nerves dissected, and selected fragments were fixed in osmium tetroxide 1% and phosphate buffer 0,1 M, pH 7,3, and then processed for embedding in Araldite. Were selected 2 areas of the total area of optic nerve cross-section which approximately corresponded to 30% of the nerve to perform morphological and morphometric analysis. In the morphological analysis the optic nerve of the animals in RE group showed a very similar structural aspect to the characteristics of the optic nerves in group C, and looking better than in groups A and RN, with lot of myelinated nerve fibers well grouped and compacted and this organization was present uniformly across the nerve, resulting in reduced interstitial space. In the morphometric analysis, the number of blood vessels, dietary factors, recovery and stimulation showed no interference, since all groups showed no statistically significant difference. Regarding to the number of astrocytes, the stimulation did not influence it and, regarding to diet, the group A presented a higher number of cells than groups C and RN. In assessing the number of oligodendrocytes, in relation to diet factor, RN group had a greater number of oligodendrocytes that C and A groups, which showed no significant statistically difference between them. As for the stimulation factor, the RE group had fewer oligodendrocytes than the RN. With the results can be concluded that: 1- the used diet was effective in the development of mild iron deficiency anaemia in mothers and severe in young rats; 2- the association of tactile stimulation and nutritional recovery techniques resulted in a structural reorganization of the optic nerve, similar to C group and 3- this association did not affect the number of blood vessels, however it resulted in a normalization of the number of astrocytes and oligodendrocytes

Morbid obesity, a chronic and multifactorial disease, causes metabolic disorders and increases the risk of morbidity. Its prevalence has been increasing, with alarming data in Brazil and elsewhere. Globally, Brazil ranks second in number of bariatric surgeries, but surgical treatment is a challenge for the patients and the teams that provide care for these patients. Given the above, the present study aimed to assess changes in nutritional status and identify nutritional deficiencies before and 10 years after Roux-en-Y gastric bypass. This retrospective study lasted two years and included 166 patients submitted to Roux-en-Y gastric bypass at a private clinic. The statistical analyses included the chi-square, Fisher?s, Mann-Whitney, and Wilcoxon tests, analysis of variance (ANOVA), and generalized estimating equations. The significance level was set at 5%. At the ten-year follow-up, the percentage of excess weight loss (%EWL), body mass index (BMI), and weight regain were 51.64?18.03 (p<0.0001), 32.53?4.83 kg/m2 (p<0.0001), and 41% (p<0.0001), respectively, and the lipid and blood glucose profiles had improved (p<0.0001). Iron-deficiency anemia was found in 37.5% and 45.0% of the patients who attended the 10-year follow-up based on ferritin levels <15 ug/L and <30 ug/L, respectively. The effect of time was significant for hemoglobin, ferritin, iron overload (p<0.0001), and hematocrit (p=0.0007). Vitamin D deficiency was found in 29 patients (82.86%), and high parathormone (PTH), in 13 (41.94%). The effect of time was significant for PTH (p=0.0059). In conclusion, gastric bypass was a surgical success and improved the metabolic profile. Weight regain increased over time. The nutritional outcomes were iron-deficiency anemia and vitamin D deficiency associated with secondary hyperparathyroidism. These findings reaffirm the importance of multidisciplinary care and monitoring of nutritional deficiencies for the treatment of morbid obesity.
A obesidade m?rbida considerada uma doen?a cr?nica e multifatorial, que ocasiona desordens metab?licas e aumenta o risco de morbidade, vem crescendo, com dados alarmantes no Brasil e no Mundo. O Brasil ? o segundo Pa?s que mais realiza cirurgia bari?trica, sendo o tratamento cir?rgico, um desafio para os pacientes e para as equipes envolvidas no cuidado destes pacientes. Diante do exposto, o presente trabalho teve como objetivo avaliar a evolu??o do estado nutricional e identificar as defici?ncias nutricionais no pr? e no p?s-operat?rio de pacientes submetidos ao bypass g?strico em Y-de-Roux, com 10 anos de seguimento. O estudo realizado em dois anos, com delineamento retrospectivo longitudinal, envolveu 166 pacientes submetidos ao bypass g?strico em Y-de-Roux, em uma cl?nica privada. Na an?lise estat?stica, utilizou-se os testes Qui-Quadrado, Fisher, Mann-Whitney, Anova, Wilcoxon e Equa??es de Estimativas Generalizadas. O n?vel de signific?ncia adotado foi de 5%. Os resultados deste estudo, ap?s 10 anos de seguimento, demostraram percentual de perda do excesso de peso (%PEP) de 51,64?18,03 (p<0,0001); Indice de Massa Corporal (IMC) de 32,53?4,83 kg/m2 (p<0,0001); reganho de peso de 41% (p<0,0001). O perfil lip?dico e glic?mico diminuiu ao longo de 10 anos de seguimento (p<0,0001). Dos pacientes que permaneceram no estudo at? o final de 120 meses, 37,5% e 45,0%, apresentaram diagn?stico de anemia ferropriva, considerando-se os crit?rios utilizados de ferritina <15 ug/L e ferritina <30 ug/L, respectivamente. O efeito do tempo foi significativo para a hemoglobina, ferritina e sobrecarga de ferro, (p<0,0001) e hemat?crito (p=0,0007). Em rela??o ao metabolismo do c?lcio, 82,86% (29), apresentaram n?veis de defici?ncia de vitamina D e 41,94% (13) apresentaram PTH elevado. O efeito do tempo foi significativo para o PTH (p=0,0059). Em conclus?o, pacientes submetidos ao bypass g?strico, apresentaram sucesso cir?rgico e melhora do perfil metab?lico. O reganho de peso aumentou com o tempo de seguimento. A anemia ferropriva e a defici?ncia de vitamina D, associada ao hiperparatireoidismo secund?rio, foram desfechos nutricionais encontrados Tais achados reafirmam a import?ncia do cuidado multidisciplinar e ? aten??o ?s defici?ncias nutricionais para o tratamento da obesidade m?rbida.

Full textThe aim was evaluate the association between iron deficiency and severe early childhood caries in children between 24 and 36 months; rising hematological indicators that can be related to early establishment of the disease. At intraoral exam the caries index (def) praised by WHO, and the presence of active white spots (AWP) were evaluated. All the children were submitted to a bloody collection, being the samples frozen and sent to processing at Hemomar Analysis Laboratory (São Luís, Maranhão, Brazil), for the evaluation of hemoglobin, ferritin and serumal iron levels. The obtained information was consolidated in data bank of STATA 9.0 program. The Poisson regression model was applied to the association between dependent variables (def and AWP) and others, being the prevalence ratio and confidence interval (IC 95%). It was certified that the higher the number of caries cavities in children, the lower are the hemoglobin levels in serum. About caries activity (AWP), it was observed that the higher the number of initial lesions, the lower is the levels in serum of hemoglobin, ferritin and serumal iron. The data show that the levels in serum of the marked variables of iron deficiency anemia are lower when the number of caries lesions in children with severe early childhood caries is higher.
O objetivo foi avaliar a associação entre deficiência de ferro e cárie de estabelecimento precoce severa em crianças de 24 a 36 meses; levantando-se indicadores de riscos hematológicos que possam estar relacionados ao estabelecimento precoce da doença. No exame clínico intra-bucal foram avaliados os índices de cárie (ceo), preconizado pela OMS, e presença de manchas brancas ativas (MBA).Todas as crianças foram submetidas a uma coleta de sangue , sendo as amostras mantidas refrigeradas e enviadas para processamento no Laboratório de Análises do Hemomar (São Luís-MA), para avaliação dos níveis de hemoglobina, ferritina e ferro sérico.As informações obtidas foram consolidadas em bancos de dados do programa STATA 9.0.Foi aplicada uma regressão de Poisson para associação entre as variáveis dependentes (ceo e MBA) e demais variáveis, sendo a razão das prevalências (IR) e intervalo de confiança (IC 95%).Foi observado que quanto maior o número de cavidades de cárie nas crianças, menores foram os níveis séricos da hemoglobina. Em se tratando da atividade da doença cárie (MBA), foi encontrado que quanto maior o número de lesões iniciais, menores foram os níveis séricos de hemoglobina, ferritina e ferro sérico. Os dados mostram que os níveis séricos das variáveis marcadoras da anemia ferropriva são menores quanto maior o número de lesões cariosas em crianças com cárie precoce severa.

Full textObjective: To investigate the nutritional status, food consumption and complementary feeding practices in children aged between 6 and 24 months living in Acrelândia, Acre State, Westhern Brazilian Amazon. Methods: A population-based, cross-sectional study was conducted within an urban area of Acrelândia. Information on sociodemographic conditions, morbidity and breast feeding were collected using structured questionnaires. Food consumption and practices were analyzed based on food history data. Anthropometric assessment entailed weight and height measurements according to the 2007 World Health Organization (WHO) standard distribution curve. Stool samples were obtained and subjected to parasitological examination. Assessment of hemoglobin, ferritin, soluble transferrin receptor, Vitamin B12 and retinol serum levels was performed on fasting venous blood samples. Results: Of the total 166 children studied, the prevalence of stunted height/age and anemia was 12% and 40%, respectively. Out of the anemic children, 95% presented with iron-deficient anemia. The overall prevalence of iron deficiency was 44%. Intestinal parasites were detected in 26% of the stool samples, where 80% of these infections were caused by Giardia lamblia. Vitamin A and B12 serum levels were below normal thresh holds in 15% and 12% of children, respectively. Breast feeding was started by the vast majority of mothers (99%) although exclusive breast feeding up to the sixth month was reported by only 10% of participants. The intake of cows milk was high from the first months of life, where 70% of the children studied were consuming cows milk at 8 months of age. The frequency of porridge (cows milk and maize flour) consumption increased with age: 37% of the children aged between 6 and 8 months, 48% between 9 and 11 months and 64% between 12 and 24 months, reported regular porridge consumption. Food consumption at levels below WHO recommendations (2004) were observed for the following nutrients (% of children): folic acid (33%), Vitamin C (40%), Vitamin A (42%), zinc (46%) and iron (71%). The bioavailability of iron in the diet was approximately 8%, with 78% of the childrens diets being classified as having low or very low bioavailability. The foods which contributed most to total energy ingested were cow\'s milk and mother\'s breast milk, and in terms of iron, were the thickening agents used in porridge making. Conclusion: These results suggest that interventions should be introduced to promote exclusive breast feeding up to the sixth month, along with the introduction of healthy complementary foods and feeding practices. Improvements in bioavailability of iron in the diet are essential, through higher total iron consumption (meat, beans and meat/bean stock) and Vitamin C (encouragement to consume more fruit and vegetables) from the outset of introducing complementary food, while consumption of foods rich in iron inhibitors such as coffee, tea, thickeners and cows milk should be avoided. As child age increases, porridge consumption should be gradually substituted by encouraging the consumption of alternative foods available to the family.
