Magnitude, geographic distribution and trends of anemia in preschoolers, Brazil

OBJECTIVE To assess the magnitude, geographical distribution and trends of the prevalence of nutritional anemia among preschoolers and to identify risk groups in the state of Paraiba, Brazil. METHODS A cross-sectional survey with multistage random sampling procedure was conducted in 8 urban municipalities of three mid-regions (Zona da Mata, Agreste and Sertão) in the state of Paraíba in 1992. A total of 1,287 preschoolers of both sexes were selected. Hemoglobin was determined by the cyanometahemoglobin method in venous blood, employing <11 g/dl as the cut-off for anemia. Statistical analysis of proportions employed the chi Square test, whereas for means Mann-Whitney and Kruskal-Wallis were the choice, all with confidence interval of 95%. RESULTS The prevalence of anemia was 36.4% (CI 33.7 - 39.1) in the state of Paraiba, greater (p=0.00) than that observed (19.3%, CI 17.3 - 21.5) in 1982. Only 1.0% (CI 0.61 - 1.8) and 6.8% (CI 5.5 - 8.3) of anemia cases were classified as severe and moderate, respectively. Boys presented lower mean hemoglobin concentration (p=0.00), and children under age 3 comprised the biological group of highest susceptibility for deficiency status (p= 0.00). It was found that the second year of life is the most critical for developing nutritional deficiency (p= 0.00). The Agreste mid-region revealed to be the geographical area of highest risk (p= 0.00), outlining a new epidemiological dynamics when compared to the year 1982, when the drought-ridden Sertão region were the geographical area at greatest risk of deficiency. CONCLUSIONS According to international epidemiological criteria, anemia in the studied regions represents a public health problem of moderate degree Assuming the analytical comparability of the 1982 and 1992 cross-sectional surveys, it suggests an increasingly prevalence of nutritional anemia (+88.5%) in all 3 mid-regions in a 10-year-period (1982-92).

Effect of vitamin D3 supplementation and influence of BsmI polymorphism of the VDR gene of the inflammatory profile and oxidative stress in elderly women with vitamin D insufficiency: Vitamin D3 megadose reduces inflammatory markers.

OBJECTIVE This study aimed to evaluate the effect of vitamin D3 megadose supplementation and influence of BsmI polymorphism in the VDR gene on the inflammatory profile and oxidative stress in elderly women with vitamin D deficiency. METHODS A double blind, randomized, placebo-controlled trial was conducted with 40 elderly women (aged 68±6 years) diagnosed with vitamin D insufficiency (24.7±3.1 ng/mL). Participants were distributed into a supplementation group that received 200,000 IU of vitamin D3 (SG; n=20) and a placebo group (PG; n=20). Blood samples were collected at baseline and after intervention to analyse the 25(OH)D, parathyroid hormone, serum calcium, ultra-sensitive C-reactive protein (us-CRP), alpha 1-acid glycoprotein (AGP-A), total antioxidant capacity (TAC), and malondialdehyde (MDA) levels, as well as the renal and hepatic function, and genotyping was performed for BsmI polymorphism. RESULTS Four weeks after supplementation, elderly women in the SG group showed a significant increase in the serum concentration of 25(OH)D (25.29±2.8 to 31.48±6.0; p=0.0001), which was followed by increased TAC (65.25±15.66 to 71.83±10.71; p=0.03) and decreased serum PTH (46.32±13.2 to 35.45±11.0; p=0.009), us-CRP (0.38±0.3 to 0.19±0.1; p=0.007) and AGP-A levels (75.3±15.4 to 61.1±5.9; p=0.005). Changes in BP, ANAC and MDA were not observed. The 25(OH)D and PTH, us-CRP and AGP-A levels of participants with the BB/Bb genotype were more responsive to supplementation, but their other markers did not change. CONCLUSIONS Supplementation with a vitamin D3 megadose reduced inflammatory markers and increased the total antioxidant capacity in elderly women with vitamin D insufficiency. The 25(OH)D, PTH, us-CRP and AGP-A levels of elderly patients with the BB/Bb genotype were more responsive to supplementation compared with those with the bb genotype.

Berinjela (Solanum melongena L.): mito ou realidade no combate as dislipidemias?

High cholesterol is considered one of the most important factors for the coronary arterial disease development. As a result, effective treatments with medicine were developed to fight it; even so, they present high cost and collateral effects. Considering this fact, patients have required treatments using popular and scientific well-known food whose effect is to decrease the fat rate. Several researches are being carried out with eggplant with the objective of investigating their possible effects in the reduction of the blood fat. The species Solanum melongena has been the target of several studies due to its popular use in weight-loss diets, as it increases the elimination of fat and fights the exceeding cholesterol. This work aims at showing a literature review about the species Solanum melongena, of the family Solanaceae, associated with the reduction of fats by the organism. For this purpose twenty-five references were consulted.

Deficiências de micronutrientes no pré-operatório de cirurgia bariátrica

INTRODUCAO: Achados epidemiologicos tem demonstrado o aumento da prevalencia de obesidade em diversos segmentos da populacao mundial. Neste contexto, a cirurgia bariatrica e aceita, atualmente, como a ferramenta mais eficaz no tratamento e controle da obesidade morbida. Varios estudos vem avaliando o estado nutricional apos operacoes bariatricas, principalmente as mistas, detectando reducao no consumo alimentar de proteinas, vitaminas e minerais. No entanto, outros investigam a presenca de deficiencias nutricionais antes da realizacao da operacao, que podem ser agravadas com o procedimento cirurgico, resultando em complicacoes pos-operatorias graves. OBJETIVO: Analisar a literatura para as deficiencias de micronutrientes em pacientes obesos antes da cirurgia bariatrica. METODO: Realizou-se revisao sistematica em bases eletronicos, a saber: PubMed/Medline, Scielo, Lilacs e Bireme. As seguintes palavras-chave foram utilizadas individualmente ou em associacao: bariatric surgery, obesity, preoperative, gastric bypass, vitamin deficiencies, mineral deficiencies and absorption nutrient. Foram incluidos 40 artigos de revisao e originais, publicados entre 2005 a 2012. RESULTADOS: Encontrou-se como consenso o fato de que a combinacao de deficiencias nutricionais no pre-operatorio, as restricoes e ma absorcao induzidas pela cirurgia bariatrica podem levar a importante deficits nutricionais durante o periodo pos-operatorio tardio, principalmente de micronutrientes, resultando em complicacoes graves. CONCLUSAO: A alta ocorrencia de deficiencia de micronutrientes no pre-operatorio detectada em obesos morbidos candidatos a cirurgia bariatrica, somado a um processo disabsortivo, pode envolver pior prognostico durante o periodo pos-operatorio tardio. Avaliacao pre-operatoria dos parâmetros nutricionais e da ingestao de alimentos e recomendado em conjunto com as intervencoes.

Uso de probióticos na rinite alérgica

UNLABELLED Probiotics are live microorganisms used as supplementary food, usually lactic acid bacteria that can change either the composition and/or the metabolic activities of the gut microbiota modulating the immune system in a way that benefits the persons health. AIM To review the use of Probiotics (Lactobacillus and Bifidobacterium) in allergic rhinitis patients. MATERIALS AND METHODS Pubmed original articles were used as data source. RESULTS Results indicate that probiotics, Lactobacillus and Bifidobacterium appear to prevent allergy recurrences, alleviate the severity of symptoms and improve the quality of life of patients with allergic rhinitis. This happens because of the immune system modulation through the induction of cytokine production which cause a dominant TH1 response in allergic patients by modulating the TH1/TH2 balance effect. CONCLUSION The use of probiotic bacteria could be an effective and safe way to prevent and/or treat allergic rhinitis, but its underlying mechanisms remain unclear. Therefore, clinical studies using probiotics and dietary intervention should be the focus of future research to enable a more widespread use.

Programa de intervenção nutricional associado à atividade física: discurso de idosas obesas

Obesity is a complex nutritional problem with social and psychological dimensions, which affects individuals of all ages. In addition to presenting risk factors for some diseases, obesity may interfere with the quality of life of the elderly. This qualitative study of an exploratory nature investigated the discourse of obese elderly women regarding their participation in a nutritional intervention program associated with physical activity. Eighteen obese elderly women attending Centers of Reference and Citizenship in the city of João Pessoa, state of Paraiba, Brazil were enlisted in the study. Interviews using a series of questions that addressed the core issue pertaining to the scope of the study was the technique used for data collection. The data obtained were analyzed by the collective subject discourse (CSD) technique. The following central ideas emerged from CSD: changes in lifestyle, in eating habits, in health and in self-esteem. The core ideas reflected the value attributed to the aforesaid program for promotion of health of the group of elderly women who participated in the study. It is hoped that this research might elicit further investigation in the area of health of the elderly.

Potential ergogenic activity of grape juice in runners

Recent studies have indicated that certain food products have ergogenic potential similar to that of sports supplements. The present study aimed to investigate the potential ergogenic effect of integral purple grape juice on the performance of recreational runners. Twenty-eight volunteers of both sexes (age, 39.8 ± 8.5 years; peak oxygen consumption, 43.2 ± 8.5 mL/(kg·min)) were randomized into either a group that received grape juice (grape juice group (GJG), n = 15; 10 mL/(kg·min) for 28 days) or a group that received an isocaloric, isoglycemic, and isovolumetric control beverage (control group (CG), n = 13). A time-to-exhaustion exercise test, anaerobic threshold test, and aerobic capacity test were performed, together with assessments of markers of oxidative stress, inflammation, immune response, and muscle injury, performed at baseline and 48 h after the supplementation protocol. The GJG showed a significant increase (15.3%) in running time-to-exhaustion (p = 0.002) without significant improvements in either anaerobic threshold (3.6%; p = 0.511) or aerobic capacity (2.2%; p = 0.605). In addition, GJG exhibited significant increases in total antioxidant capacity (38.7%; p = 0.009), vitamin A (11.8%; p = 0.016), and uric acid (28.2%; p = 0.005), whereas α-1-acid glycoprotein significantly decreased (20.2%; p = 0.006) and high-sensitivity C-reactive protein levels remained unchanged. In contrast, no significant changes occurred in any of these variables in the CG. In conclusion, supplementation with purple grape juice shows an ergogenic effect in recreational runners by promoting increased time-to-exhaustion, accompanied by increased antioxidant activity and a possible reduction in inflammatory markers.

Concentrações de 25-hidroxivitamina D e níveis pressóricos em idosos hipertensos

OBJECTIVE: To evaluate the prevalence of inadequate vitamin D status and its relationship with associated factors in 91 elderly hypertensive patients in Joao Pessoa, PB/BR. MATERIALS AND METHODS: In a cross-sectional study, levels of 25-hydroxyvitamin D of 91 elderly patients were compared with biochemical, anthropometric, and dietary data, type of skin, exposure to sunlight, and blood pressure. RESULTS: The prevalence of inadequate vitamin concentrations (25-hydroxyvitamin D < 29 ng/mL) was 33%. The concentration of serum 25-hydroxyvitamin D was inversely associated with systolic blood pressure and positively associated with weekly fish consumption. The other variables showed no significant association with 25-hydroxyvitamin D. CONCLUSION: The prevalence of inadequate vitamin D concentrations was related with higher blood pressure in elderly patients. Moreover, greater fish weekly consumption influenced greater 25-hydroxyvitamin D concentration.

Supplementation with Watermelon Extract Reduces Total Cholesterol and LDL Cholesterol in Adults with Dyslipidemia under the Influence of the MTHFR C677T Polymorphism

Dyslipidemia and genetic polymorphisms are associated with increased risk for developing cardiovascular diseases, and watermelon appears to have the potential to improve hyperlipidemia due to the presence of nutrients such as arginine and citrulline. Objective: To test the hypolipidemic effect of watermelon extract (Citrullus lanatus) and the influence of the methylenetetrahydrofolate reductase genotype (MTHFR C677T) on supplementation response. Methods: This is an experimental clinical phase II randomized and double-blind study. Forty-three subjects with dyslipidemia were randomly divided into 2 groups: experimental (n = 22) and control (n = 21) groups. The subjects were supplemented daily for 42 days with 6 g of watermelon extract or a mixture of carbohydrates (sucrose/glucose/fructose). Results: The use of watermelon extract reduced plasma total cholesterol (p < 0.05) and low-density lipoprotein (p < 0.01) without modifying triglycerides, high-density lipoprotein, and very low-density lipoprotein values. Only carriers of the T allele (MTHFR C677T) showed decreasing concentrations of low-density lipoprotein (p < 0.01). No changes in anthropometric parameters analyzed were observed. This is the first study to demonstrate the beneficial effect of the consumption of watermelon extract in reducing plasma levels of lipids in humans. The MTHFR C677T polymorphism did not affect the plasma lipid concentration but made individuals more responsive to treatment with watermelon. Conclusions: The consumption of this functional food represents an alternative therapy in the combined treatment of patients with dyslipidemia, promoting health and minimizing the development of risk factors for cardiovascular diseases.

Relation between glucose levels, high-sensitivity C-reactive protein (hs-CRP), body mass index (BMI) and serum and dietary retinol in elderly in population-based study

The aim of this study was to evaluate the relationships between fasting glucose levels, hs-CRP, BMI and serum retinol and diet in elderly people. For this study, a cross-sectional, epidemiological, population-based format was adopted. One hundred and sixty-three individuals between 60 and 90 years of age participated; the participants were from different socioeconomic and health backgrounds, except for the individuals diagnosed with diabetes. Most subjects had serum concentrations in the reference ranges for all variables. There was not a significant relationship between fasting glucose and serum retinol or diet. There was a significant correlation between hs-CRP and BMI (r=0.22, p=0.0082) and hs-CRP and total calorie intake (p=0.0091), which reinforces the notion that an increased intake of calories results in being overweight and/or obese. Considering the importance of vitamin A in various physiological processes, more studies on these relationships are necessary to establish a recommendation of vitamin A for the treatment and prevention of changes in fasting glucose and obesity in the elderly population.
