RESUMO

Menopause is a stage of hormonal imbalance in women which, in addition to other physiopathological consequences, poses a risk of deficiency of key micronutrients such as magnesium and vitamin D. A study was made of the influence of a magnesium intervention upon vitamin D status in a postmenopausal population from the province of Granada (Spain). Fifty-two healthy postmenopausal women between 44-76 years of age were included. Two randomized groups-placebo and magnesium (500 mg/day)-were treated during eight weeks. Nutrient intake was assessed using questionnaires based on 72-h recall. Vitamin D was analyzed by liquid chromatography-tandem mass spectrometry. Baseline vitamin D proved deficient in over 80% of the subjects. The administration of magnesium resulted in significantly increased vitamin D levels in the intervention group versus the controls (p < 0.05). Magnesium supplementation improved vitamin D status in the studied postmenopausal women.

Introduction: Cancer is the name given to a set of diseases that have in common the disorderly growth of cells. Impaired nutritional status is frequent in oncologic patients and negatively interferes in the patient's daily life abilities. Objective:To evaluate the nutritional status and functional capacity of oncologic patients undergoing chemotherapy treatment. Method: Cross-sectional design, observational epidemiological study, with a sample obtained by convenience from 213 individuals undergoing outpatient chemotherapy treatment. The interviewees answered to the Patient-Generated Subjective Global Assessment (PG-SGA); functional ability was verified using handgrip strength (HGS) (hand dynamometry) and through the Eastern Cooperative Oncology Group (ECOG) scale for performance scale. Results: 213 patients were evaluated, 56.3%, elderly and 54.0%, females. Excluding head and neck neoplasms, there was a higher prevalence of well-nourished individuals according to PG-SGA (p=0.004); in relation to the body mass index (BMI), except for individuals with breast cancer, the highest prevalence was eutrophy (p=0.010). Individuals with adequate HGS (54.9%) were well nourished according to the SGA (91.5%) (p≤0.0001) and overweight according to the BMI (46.2%) (p=0.010). Still, fully active individuals (69.0%), were well nourished according to SGA (89.8%) (p≤0.0001) and eutrophic according to BMI (44.2%) (p=0.003), showing a significant difference in the assessment of nutritional status with functional capacity. Conclusion: The study demonstrated that the majority of cancer patients undergoing chemotherapy had satisfactory nutritional status, adequate muscle strength and were fully active.

RESUMO

BACKGROUND: Zinc is an essential micronutrient for human beings and its deficiency affects their normal growth and development. OBJECTIVE: The main aim was to evaluate the effect of two doses of zinc supplementation (ZS) on the nutritional status in chronic kidney disease (CKD) children. METHODS: A randomized-trial multicentric study was conducted in 48 CKD (23 females) patients under 18-years-old, for a year. At random, participants took 30 or 15 mg/day of ZS, respectively. Anthropometric measurements and biochemical analysis were performed. Hypozincemia was determined by serum zinc concentration (SZC) using atomic absorption spectrophotometry. The positive or negative change in patients' body mass index (BMI) Z-score, serum albumin, zinc and C-reactive protein (CRP) levels were used to evaluate the effect of ZS. RESULTS: Mean SZC was normal before and after ZS. Despite ZS, there were no significant changes in serum albumin, zinc and CRP levels. A positive and significant association was observed between SZC and serum albumin before (p = 0.000) and after (p = 0.007) ZS. In both groups of ZS, there was a small but positive and significant change in body mass and normalization in BMI Z-score, hypoalbuminemia, hypozincemia and high CRP, especially with 30 mg/day of ZS. CONCLUSIONS: Zinc supplementation may be beneficial for nutritional status in children and adolescents with CKD.

RESUMO

The dispersal of insects is determinant in the colonization of new areas and the propagation of insecticide resistance. Nutritional status and reproductive characteristics determine the colonization capacity after the dispersal event. Studies about of the effects of dispersal on reproduction in triatomines are few and none in resistant insects. The aim was to determine the effects of nutritional state and dispersal on the subsequent reproductive potential in Triatoma infestans (Klug, 1834) susceptible and resistant to deltamethrin. Three nutritional states were obtained with the number of feeds (NF) offered (0, 1 or 2). The resistant females were evaluated only with NF1. The experimental arena was 10 m long and contained two shelters. Groups of 30 virgin females of each NF were released in one of the shelters and were able to move during 3 days/nights. Females without possibility of dispersal were the controls. The reproductive parameters were determined on the couples between the experimental females and males from the breeding. The results showed that most of the females dispersed by walking. The dispersal had effects on the reproduction of the deltamethrin-susceptible females and this depended on the number of feeds. Fecundity, fertility and the proportion of females that oviposited were higher in females dispersed with two feeds but was lower in females dispersed with less feeds. In addition, the effect of the dispersal on the reproduction and the life time also depended of the toxicological phenotype. The resistant insect oviposited in higher proportion and showed greater fecundity and more weeks of life when they dispersed that when they did not do it, and was opposite to that observed in susceptible ones. Finally, the resistance to insecticide had an effect on the reproduction and the life span and this effect depended on whether the insects dispersed or not.

RESUMO

A soy protein-based supplement may optimize bone health, support physical growth, and stimulate bone formation. This study aimed to assess the effect of a daily soy protein supplement (SPS) on nutritional status, bone formation markers, lipid profile, and daily energy and macronutrient intake in children. One hundred seven participants (62 girls), ages 2 to 9, started the study and were randomly assigned to lunch fruit juice with (n = 57, intervention group) or without (n = 50, control group) addition of 45 g (230 Kcal) of a commercial SPS during 12 months; 84 children (51 girls, 33 boys) completed the study (45 and 39 intervention and control, respectively). Nutritional assessment included anthropometry and nutrient intakes; initial and final blood samples were taken; insulin-like growth factor-I (IGF-I), osteocalcin, bone specific alkaline phosphatase (BAP), insulin-like growth factor binding protein-3 (IGFBP-3), cholesterol, triglycerides, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were analyzed. Statistically significant changes (p < .05) in body mass index and weight for age Z scores were observed between groups while changes in body composition were not. Changes in energy, total protein, and carbohydrate intakes were significantly higher in the intervention group (p < .01). Calorie intake changes were statistically significant between groups (p < .001), and BAP decreased in both groups, with values within normal ranges. Osteocalcin, IGFBP-3, and lipid profile were not different between groups. IGF-I levels and IGF/IGFBP-3 ratio increased significantly in both groups. In conclusion, changes in macronutrient and energy intake and nutritional status in the intervention group compared to control group may ensure harmonious and adequate bone health and development.

RESUMO

Objective: To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. Methods: Cross-sectional study with 108 crack users. Anthropometric data were assessed through body mass index (BMI) and bioimpedance (BIA) measurements. A blood test to analyze hematocrit, hemoglobin, glucose, and lipid profiles was also performed. Crack use was determined through a standardized interview. Results: Based on BMI and BIA, most individuals were eutrophic (about 70%). Regarding hematological parameters, we found that hemoglobin and hematocrit levels were below normal for 32.4 and 30.6% of patients, respectively. Considering normal parameters, a large part of the sample (60.2%) had low levels of HDL cholesterol and high levels of triglycerides (38%). There were no significant correlations between drug profile and nutritional variables. Conclusion: This is a pioneering study that examines the nutritional status of crack users. Our results showed that most crack users present normal anthropometric findings and the prevalence of underweight is low. However, blood analysis showed changes and a specific type of malnutrition.

RESUMO

OBJECTIVE: To analyze the nutritional status of selenium and verify the effect of its supplementation in pediatric patients during 14 days of parenteral nutrition (PN). METHOD: This is a series of cases with patients followed for two weeks while using PN. Data collection was performed at the beginning (T0), in the 7th (T1) and 14th days of PN (T2). The supplemented group received 2 µg/kg/day of selenous acid. Weight and height were measured for nutritional status assessment. Tests requested: plasma selenium, albumin, pre-albumin, C-reactive protein (CRP), total cholesterol and HDL-cholesterol. RESULTS: Fourteen (14) patients with inflammatory process and with low or very low weight for their ages were evaluated. In both groups (with and without supplementation), all patients had low selenium levels. Median plasma selenium concentrations were 17.4 µg/L (T0), 23.0 µg/L (T1) and 20.7 µg/L (T2). Increase and reduction of selenium occurred both in patients with high CRP and in those presenting normalization of this parameter. CONCLUSION: Lower plasma selenium levels have been detected since the start of the research and supplementation (2 µg/kg/day of selenous acid) was not to enough to approach the reference values.

RESUMO

Intestinal obstruction leads to blockage of the movement of intestinal contents. After relieving the obstruction, patients might still suffer with compromised immune function and nutritional deficiency. This study aimed to evaluate the effects of Sijunzi decoction on restoring the immune function and nutritional status after relieving the obstruction. Experimental rabbits (2.5±0.2 kg) were randomly divided into normal control group, 2-day intestinal obstruction group, 2-day natural recovery group, 4-day natural recovery group, 2-day treated group, and 4-day treated group. Sijunzi decoction was given twice a day to the treated groups. The concentration of markers was analyzed to evaluate the immune function and nutritional status. The concentration of interleukin-2, immunoglobulins and complement components of the treated groups were significantly higher than the natural recovery group (P<0.05). The levels of CD4+ and CD4+/CD8+ increased then decreased in the treated groups. The levels of tumor necrosis factor-α and CD8+ were significantly lower than the natural recovery group. The level of total protein in the treated groups also increased then decreased after relieving the obstruction. The levels of albumin, prealbumin and insulin-like growth factor-1 were significantly higher in the treated groups than in the natural recovery group (P<0.05). Transferrin level in the treated groups was significantly higher than the obstruction group (P<0.05). Sijunzi decoction can lessen the inflammatory response and improve the nutrition absorption after relieving the obstruction.

RESUMO

BACKGROUND: This investigation determines the nutritional state of serum and red blood cell (RBC) folate concentration and their relation with intake of folate, B6 ,and B12 , with serum vitamin B12 , and with genetic variants after provision of 400 µg/day of folic acid for 3 months to a group of 34 Colombian women of reproductive age. METHODS: We evaluated nutrient intake using 24-hr recall, assessing the levels of serum folate, RBC folate, serum B12 , and homocysteine, as well as determining genetic variants of the enzyme MTHFR (C677T and A1298C) and CßS (844ins68pb). RESULTS: The results show that following intake of 400 µg/day of folic acid, the risk of folate deficiency as seen in regular dietary intake disappears and the nutritional status of this nutrient is increased (p < 0.001). With respect to vitamin B12, the risk of serum deficiency with folic acid consumption increased slightly, and those that were found to be B12 deficient after supplementation also had decreased levels of serum homocysteine. Genetic factors did not influence the nutritional status of folate, although an association was found between the intake of nutrients and biochemical indicators. CONCLUSION: Given the results of our study, subsequent studies evaluating folic acid supplementation should also consider evaluating the status of B12 and B6 , and serum and RBC folate, as they participate interdependently in the cycle of folate and methionine and in homocysteine metabolism.Birth Defects Research 109:564-573, 2017.© 2017 Wiley Periodicals, Inc.

RESUMO

RESUMO O leite materno é o alimento ideal para qualquer recém-nascido devido à sua composição nutricional balanceada e à sua capacidade de gerar imunidade. Seu uso tem sido muito incentivado nas Unidades de Terapia Intensiva (UTI) e Unidades Intermediárias (UI), sendo ofertados tanto o leite materno extraído diretamente do seio materno, quanto o proveniente de bancos de leite humano. Dessa forma, este estudo teve como propósito acompanhar e comparar recém-nascidos com e sem o uso de aditivo fortificante do leite materno, em UTI neonatal. O estudo foi observacional do tipo coorte, com grupo controle, realizado em uma maternidade pública, nas unidades de terapia intensiva e terapia intermediária neonatais. Foram acompanhados 26 recém-nascidos pré-termo, divididos em dois grupos, um deles constituído por 13 recém-nascidos em aleitamento materno exclusivo (grupo controle) e outro composto por 13 recém-nascidos em uso de leite materno, com aditivo fortificante. Para a análise de dados, foi utilizada estatística descritiva simples, calculando-se distribuições de frequências, cálculo das médias, desvio-padrão e realizações dos testes estatísticos. O ganho de peso médio no período do estudo foi significativamente maior no grupo que recebeu leite materno com aditivo. Em relação ao comprimento e ao perímetro cefálico não foram observadas diferenças estatísticas significativas entre os grupos. Constata-se que o uso de aditivo no leite materno humano cru ou processado proporciona melhor ganho de peso, favorecendo a recuperação do estado nutricional.

RESUMEN La leche materna es el alimento ideal para cualquier recién nacido debido a su composición nutricional balanceada y a su capacidad de generar inmunidad. Su uso ha sido muy fomentado en las Unidades de Cuidados Intensivos y Unidades Intermediarias, siendo ofertadas, tanto la leche materna, extraída directamente del seno materno, como la proveniente de bancos de leche humana. El propósito del estudio fue el de acompañar y comparar a los recién nacidos con y sin el uso de aditivo fortificante de la leche materna, en UCI neonatal. Este estudio fue observacional del tipo cohorte, con grupo control, realizado en una maternidad pública, en las unidades de cuidados intensivos y cuidados intermediarios neonatales. Fueron acompañados 26 recién nacidos pretérmino, divididos en dos grupos, uno de ellos constituido por 13 recién nacidos en lactancia materna exclusiva (grupo control) y otro compuesto por 13 recién nacidos en uso de leche materna, añadido de aditivo fortificante. Para el análisis de datos fue utilizada estadística descriptiva simple calculando distribuciones de frecuencias, cálculo de los promedios, desviación típica y realizaciones de las pruebas estadísticas. El aumento de peso promedio en el período del estudio fue significativamente mayor en el grupo que recibió leche materna con aditivo. En relación a la longitud y al perímetro cefálico no fueron observadas diferencias estadísticas significativas entre los grupos. Se constata que el uso de aditivo en la leche materna humana cruda o procesada proporciona mejor aumento de peso, favoreciendo la recuperación del estado nutricional.

ABSTRACT Breast milk is the ideal food for any newborn regarding the balanced nutritional composition and its ability to generate immunity. Its use has been greatly encouraged in intensive care units and Intermediate Unit, both the milk extracted directly from the mother's womb, as the one from the milk bank. The purpose of the study was to monitor and to compare infants with and without use of breast milk fortifier in neonatal intensive care unit. It was an observational cohort study with a control group, performed in a public hospital, in intensive care units and neonatal intermediate unit. They were followed 26 preterm infants, divided into two groups consisting of 13 preterm infants in exclusively breastfed (control group) and 13 preterm infants in use of breast milk fortifier with additive added. The average weight gain was significantly higher in the group receiving breast milk containing additive. In relation to the length and head circumference, significant differences were not observed. For data analysis, we used simple descriptive statistics by calculating frequency distributions, calculation of averages, standard deviation and achievements of the statistical tests. The average weight gain during the study period was significantly higher in the group receiving breast milk with additives. Regarding the length and head circumference, statistical differences were not significant between groups. It appears that the additive used in raw or processed human breast milk provides better weight gain, facilitating recovery of nutritional status.

RESUMO

BACKGROUND: The prevalence of obesity has increased at an alarming rate worldwide. Some studies have observed an association between iron (Fe) deficiency (ID) and obesity, however more research is needed. OBJECTIVE: To assess whether body mass index (BMI) is associated with both Fe absorption and Fe status. METHODS: A cross sectional sample of 318 Chilean childbearing age women was studied. The women received either a single dose of 0.5mg of Fe (n=137, group 1) or 3mg of Fe plus ascorbic acid (1:2 molar ratio) (n=181, group 2), both as FeSO4 with labeled radioisotopes. Fe absorption was assessed through radio Fe erythrocyte incorporation. Fe status was determined by hemoglobin (Hb), mean corpuscular volume, serum Fe, total iron binding capacity, transferrin saturation, erythrocyte Zn protoporphyrin and serum ferritin (SF). RESULTS: 29%, 47% and 24% of the women were classified as normal, overweight or obese, respectively. Fe absorption was significantly lower in obese women (p<0.05). In group 1, the geometric mean and range ±1 SD of the percentage of Fe absorption for normal-weight women was 32.9% vs. 19.7% in obese. For group 2, this percentage was 36% vs. 30%, respectively (2-way ANOVA: BMI classification and Fe dose p<0.05; interaction p=0.34). Although Fe absorption was lower in obese women, they had higher SF (p<0.01) and Hb (p<0.05) concentrations. CONCLUSION: Although we did not observe a relationship between BMI and Fe status, obese women displayed lower Fe absorption compared with overweight and normal weight women, possibly due to subclinical inflammation associated with obesity.

RESUMO

The recognized antagonistic actions between zinc and iron prompted us to study this subject in children. A convenience sample was used. Thirty healthy children between 8 and 9 years of age were studied with the aim of establishing the effect of a 3-mo oral zinc supplementation on iron status. Fifteen individuals were given a placebo (control group), and 15 were given 10 mg Zn/day (experimental group). Blood samples were collected at 0, 60, 120, 180 and 210 min after a 12-h overnight fast, before and after placebo or zinc supplementation. This supplementation was associated with significant improvements in energy, protein, fat, carbohydrate, fiber, calcium, iron, and zinc intake in accordance with the recommendations for age and sex. The basal serum zinc concentration significantly increased after oral zinc supplementation (p < 0.001). However, basal serum iron concentrations and area under the iron curves significantly decreased in the experimental group (p < 0.0001) and remained at the same level throughout the 210-min study. The values obtained for hemoglobin, mean corpuscular volume, ferritin, transferrin, transferrin saturation, ceruloplasmin and total protein were within normal reference ranges. In conclusion, the decrease in serum iron was likely due to the effects of chronic zinc administration, and the decrease in serum iron was not sufficient to cause anemia.

RESUMO

BACKGROUND: Breast cancer (BC) represents the highest incidence of malignancy in women throughout the world. Medicinal fungi can stimulate the body, reduce side-effects associated with chemotherapy and improve the quality of life in patients with cancer. AIM: To evaluate the effects of dietary supplementation of Agaricus sylvaticus on clinical and nutritional parameters in BC patients undergoing chemotherapy. MATERIALS AND METHODS: A randomized, placebo-controlled, double-blind, clinical trial was carried out at the Oncology Clinic, Hospital of the Federal District-Brazil from September 2007 to July 2009. Forty six patients with BC, Stage II and III, were randomly assigned to receive either nutritional supplement with A. sylvaticus (2.1 g/day) or placebo. Patients were evaluated during treatment period. RESULTS: Patient supplemented with A. sylvaticus improved in clinical parameters and gastrointestinal functions. Poor appetite decreased by 20% with no changes in bowel functions (92.8%), nausea and vomiting (80%). CONCLUSION: Dietary supplementation with A. sylvaticus improved nutritional status and reduced abnormal bowel functions, nausea, vomiting, and anorexia in patients with BC receiving chemotherapy.

RESUMO

OBJECTIVE: The aim of this study was to discover the prevalence of overweight, obesity and cardiovascular risk in our HIV/AIDS outpatients according to sex, antiretroviral therapy and other variables. SUBJECTS AND METHODS: Patients underwent an anthropometric assessment. Body mass index and waist circumference were used to classify their nutritional status and their cardiovascular risk. RESULTS: The majority of the 345 patients (58.8%) were males. Obesity was detected in 8.3% of them; 34.2% were overweight, and 5.2% malnourished. Near half of them (51.3%) had some cardiovascular risk, with increased risk in 24.6% of them, and substantially increased risk in 26.7% of them. CONCLUSIONS: Overweight and obesity were highly prevalent. Women were more frequently obese (OR = 3.53; IC 95%, 1.47 < OR < 8.69), and their cardiovascular risk was often higher (OR = 6.97; IC 95%, 4.16 < OR < 11.76). The prevalence of obesity and cardiovascular risk did not change according to antiretroviral therapy or other variables.

RESUMO

An increase in the capacity of athletic performance depends on adequate nutrition, which ensures optimal function of the musculoskeletal system, including tendon stability. However, little is known about the status of tendons and extracellular matrix modifications during malnutrition and nutritional recovery when leucine is used in response to exercise conditioning. The purpose of this study was to evaluate the collagen content and biomechanical aspects of the deep digital flexor tendon (DDFT) in malnourished rats submitted to nutritional recovery (control diet or leucine-rich diet) and aerobic physical activity. After 60 days of undernourishment (6% protein diet), the malnourished rats were subsequently nutritionally recovered with a control diet or leucine-rich diet and trained or not (swimming, without overload) for 5 weeks. The biomechanical analysis and quantification of hydroxyproline were assessed in the DDFT in all experimental groups. The leucine-rich diet increased hydroxyproline content in the tension region, independently of the training. In the compression region, hydroxyproline content was higher in the malnourished and leucine-trained groups. Biomechanical analysis showed a lower load in the malnourished and all-trained groups. The lowest stress was observed with control-trained animals. The nutritional-recovered groups showed higher strain values corresponding to control group, while the lowest values were observed in malnourished and trained groups. The results suggest that a leucine-rich diet stimulates collagen synthesis of the DDFT, especially when in combination with physical exercise, and seems to determine the increase of resistance and the biomechanical characteristics of tendons.

RESUMO

Lithium salts exert electrophysiological and behavioral effects in animals and humans and have been used clinically in the treatment of bipolar disorders. Little is known about the lithium/nutrition interaction in the developing brain. This work aimed to determine, in adult rats, whether treatment with a single dose of lithium chloride (LiCl) would influence the propagation of the brain excitability-related phenomenon known as cortical spreading depression (CSD). Male well-nourished (W; fed a lab chow diet with 22% protein; n=22) and previously protein-malnourished rats (M; fed a low-quality 8% protein diet; proteins mostly from vegetable source; n=20) were treated at 75-80 days of age with a single intraperitoneal injection of either 50 mg/kg LiCl (n=9 W and 10 M rats) or saline (n=13 W and 10 M rats). When the pups were 90-110 days, CSD was elicited at the frontal cortex and recorded during 4 hours at two cortical parietal points. In malnourished, but not in well-nourished rats, lithium treatment lowered CSD velocities (P < 0.05), in comparison with saline-injected animals. In a third group (n=23), in which the low-protein diet was quantitatively corrected to 22%, the lithium effect disappeared (n=12), compared to saline (n=11). Our results demonstrate a facilitating effect of malnutrition on the CSD-impairing action of a single lithium administration, suggesting a lithium/nutrition interaction.
