Turmeric supplementation with piperine is more effective than turmeric alone in attenuating oxidative stress and inflammation in hemodialysis patients: A randomized, double-blind clinical trial.

PURPOSE: Turmeric has renop rotective effects that can act to reduce oxidative stress and inflammation in hemodialysis (HD) patients. Piperine has been indicated as a bioavailability enhancer of turmeric and consequently of its biological effects. However, data on the efficacy of the turmeric/piperine combination in HD patients are limited. We aimed to verify whether turmeric supplementation in combination with piperine has a superior effect to turmeric alone in increasing antioxidant capacity and reducing oxidative stress and inflammation in HD patients. METHODS: This randomized, double-blind clinical trial was conducted in HD patients (age 20-75 years). Patients were supplemented with turmeric (3 g/day) or turmeric/piperine (3 g turmeric + 2 mg piperine/day) for 12 weeks. Malondialdehyde (MDA), antioxidant enzymes catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), high-sensitivity C-reactive protein (hs-CRP), and ferritin were evaluated at baseline and the end of the study. RESULTS: There was a reduction in the MDA and ferritin levels in the turmeric/piperine group and in the comparison between groups at the end of the study [MDA: -0.08(-0.14/0.01) nmol/mL versus -0.003(-0.10/0.26) nmol/mL, p = 0.003; ferritin: -193.80 ±â€¯157.29 mg/mL versus 51.99 ±â€¯293.25 mg/mL, p = 0.018]. In addition, GPx activity reduced in the turmeric group (p = 0.029). No changes were observed for CAT, GR, and hs-CRP. CONCLUSION: Turmeric plus piperine was superior to turmeric alone in decreasing MDA and ferritin levels. The use of a combination of turmeric and piperine as a dietary intervention may be beneficial for modulating the status oxidative and inflammation in HD patients.

Antioxidant and anti-inflammatory response to curcumin supplementation in hemodialysis patients: A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND AND OBJECTIVES: Hemodialysis (HD) patients are vulnerable to malnutrition and cardiovascular complications due to many factors, including oxidative stress and inflammation. Curcumin supplementation is associated with attenuation of proinflammatory cytokines and increased activity of antioxidant enzymes, but its effects in HD patients are unknown. This study aimed to evaluate the effect of curcumin supplementation on oxidative stress and inflammation in HD patients. METHODS: This randomized, double-blind, placebo-controlled trial enrolled 43 HD patients and divided them into two groups: supplemented with curcumin (1 g/day) or placebo (corn starch) for 12 weeks. Demographic information and blood samples were taken at the start and the end of the study to determine serum malondialdehyde (MDA) concentrations, antioxidant enzyme activity, and high-sensitivity C-reactive protein (hs-CRP). RESULTS: The curcumin group showed a significant increase in catalase activity [Δ = 1.13 ± 2.87 versus Δ = -1.08 ± 2.68; p = 0.048] and preserved glutathione peroxidase activity [Δ = -4.23 ± 11.50 versus Δ = -14.44 ± 13.96; p < 0.01] compared with the placebo group. However, no significant changes were found in MDA concentrations, glutathione reductase activity, and hs-CRP concentrations after the intervention. CONCLUSION: Curcumin supplementation for 12 weeks had potential effects on antioxidant response, but it was not enough to reduce oxidative stress markers and inflammation in HD patients. This trial was registered at EnsaiosClínicos.gov.br under registration number RBR-2t5zpd.

Effect of Extra Virgin Olive Oil and Traditional Brazilian Diet on the Bone Health Parameters of Severely Obese Adults: A Randomized Controlled Trial.

Dietary interventions can stabilize and/or reverse bone mass loss. However, there are no reports on its effects on bone mineral density (BMD) in severely obese people, despite the vulnerability of this group to bone loss. We examine the effect of extra virgin olive oil supplementation and the traditional Brazilian diet (DieTBra) on BMD and levels of calcium, vitamin D, and parathyroid hormone (PTH) in severely obese adults. A randomized controlled trial followed-up with severely obese adults (n = 111, with mean body mass index 43.6 kg/m2 ± 4.5 kg/m2) for 12 weeks. Study participants received either olive oil (52 mL/day), DieTBra, or olive oil + DieTBra (52 mL/day + DieTBra). BMD was assessed by total spine and hip dual-energy X-ray absorptiometry. After interventions, BMD means for total spine (p = 0.016) and total hip (p = 0.029) were higher in the DieTBra group than in the olive oil + DieTBra group. Final mean calcium levels were higher in the olive oil group compared to the olive oil + DieTBra group (p = 0.026). Findings suggest that DieTBra and extra virgin olive oil have positive effects on bone health in severely obese adults. The major study was registered at ClinicalTrials.gov (NCT02463435).

Prevalence and factors associated with Metabolic Syndrome in elderly users of the Unified Health System / Prevalência e fatores associados à Síndrome Metabólica em idosos usuários do Sistema Único de Saúde

OBJECTIVE: To evaluate the prevalence and factors associated with metabolic syndrome in the elderly. METHODS: Cross-sectional study, with 133 individuals randomly selected in the Unified Health System in Goiania, Goiás. The following variables were researched: anthropometric (BMI, waist circumference, fat percentage by Dual X-ray absorptiometry), sociodemographic (gender, age, color, income, marital status and years of schooling), lifestyle (physical activity, smoking and risk alcohol consumption) and food intake (risk and protective foods). The metabolic syndrome was assessed according to harmonized criteria proposed by the World Health Organization (WHO). The combinations were tested by Poisson regression for confounding factors. RESULTS: The prevalence of metabolic syndrome was 58.65% (95%CI 49.8 - 67.1), with 60.5% (95%CI 49.01 - 71.18) for females and 55.7% (95%CI 41.33 - 69.53) for males. Hypertension was the most prevalent component of the syndrome in both men, with 80.8% (95%CI 64.5 - 90.4), and women, with 85.2% (95%CI 75.5 - 92.1). After the multivariate analysis, only the excess of weight measured by body mass index (prevalence ratio = 1.66; p < 0.01) remained associated with the metabolic syndrome. CONCLUSIONS: The prevalence of metabolic syndrome in this sample was high, indicating the need for systematic actions by health workers in the control of risk factors through prevention strategies and comprehensive care to the elderly. .

OBJETIVO: Avaliar a prevalência e os fatores associados à síndrome metabólica em idosos. MÉTODOS: Estudo transversal que incluiu 133 idosos, selecionados aleatoriamente entre os usuários da atenção básica do Sistema Único de Saúde em Goiânia, Goiás. Foram pesquisadas variáveis antropométricas (índice de massa corporal, circunferência da cintura e percentual de gordura por meio da Dual X-ray absorptiometry), sociodemográficas (sexo, idade, cor, renda, estado civil e anos de estudo), de estilo de vida (prática de atividade física, tabagismo e consumo alcoólico de risco) e consumo alimentar (alimentos protetores e de risco). A síndrome metabólica foi avaliada segundo o critério harmonizado proposto pela OMS. As associações foram testadas por meio da regressão de Poisson, para o controle dos fatores de confusão. RESULTADOS: A prevalência da síndrome metabólica encontrada foi de 58,65% (IC95% 49,8 - 67,1), sendo 60,5 % (IC95% 49,01 - 71,18) para as mulheres e 55,7% (IC95% 41,33 - 69,53) para homens. A hipertensão arterial foi o componente da síndrome mais prevalente tanto para homens, 80,8 % (IC95% 64,5 - 90,4), quanto para mulheres, 85,2 % (IC95% 75,5 - 92,1). Após análise multivariada, apenas o excesso de peso corporal medido pelo Índice de Massa Corporal (razão de prevalência = 1,66; p < 0,01), permaneceu associado à síndrome metabólica. CONCLUSÕES: A prevalência de síndrome metabólica nesta amostra foi alta, evidenciando a necessidade de atuação sistemática dos profissionais de saúde no controle dos fatores de risco, por meio de estratégias de prevenção e atenção integral ao idoso. .

Prevalence of cardiovascular risk factors in elderly individuals treated in the Brazilian Public Health System in Goiânia.

BACKGROUND: Cardiovascular risk factors (CVRF) present a high prevalence and have an impact on the morbimortality of the elderly; however, this question is still unknown by the elderly treated in the Brazilian Public Health System (SUS). OBJECTIVE: To investigate the prevalence of CVRF among the elderly treated by SUS in the city of Goiânia, state of Goiás, Brazil. METHODS: Cross-sectional study using a multiple-stage sampling method, carried out through a home-based interview with 418 elderly individuals aged > 60 years treated by SUS in the city of Goiânia, state of Goiás, Brazil. Socioeconomic and demographic data, as well as data on lifestyle, weight, height, waist circumference, blood pressure and medications used were collected. The studied CVRF were: arterial hypertension, diabetes mellitus, total obesity, central obesity, dyslipidemias, smoking, sedentary lifestyle and alcohol consumption. The Chi-square test was used for the analyses of the associations, with significance being set at 5%. RESULTS: The prevalences of the CVRF were: 80.4% of arterial hypertension; 83.3% of central obesity; 59.8% of sedentary lifestyle; 32.2% of total obesity; 23.4% of dyslipidemias; 19.1% of diabetes mellitus; 10.0% of smoking and 5.9% of alcohol consumption. As for the simultaneity, 2.4% of the elderly did not present CVRF. The simultaneity of two or more CVRF occurred in 87.3% of the elderly and was more frequent among women. CONCLUSION: The CVRF occur simultaneously in more than half of the elderly individuals, and the most prevalent ones were: arterial hypertension, central obesity and sedentary lifestyle. It is necessary to foster the strategies of health promotion and prevention of cardiovascular injury in elderly individuals treated by SUS in the city of Goiânia, especially among those with simultaneous CVRF.
