Background & Aims: Diet is a modifiable risk factor, which may influence the gene expression and the concentration of inflammatory biomarkers related to obesity and atherosclerosis. In this substudy from Brazilian Cardioprotective Nutritional (BALANCE) Program, we hypothesized that a nutritional intervention based on the usual Brazilian diet modulates the expression of genes involved with atherosclerosis and inflammatory biomarkers in male patients, in the secondary prevention for cardiovascular disease.

Methods: Six male patients, aged 45 years or older, obese, were selected to follow a qualitative-quantitative food plan for 6 months. Glycemia, insulinemia, lipid profile, plasma concentration of inflammatory biomarkers (interleukin (IL) -1β), IL-6, IL-8, IL-10, IL-12, tumor necrosis factor alpha, C-reactive protein and adiponectin, and expression of 84 atherosclerosis-related genes in total peripheral blood cells, were measured.

Results: After nutritional intervention, the participants reduced weight (p < 0.04), waist circumference (p < 0.04), Homeostasis Model Assessment index for insulin resistance (p = 0.046) and overall leukocyte count (p = 0.046) and neutrophils (p = 0.028). There was no significant modification in the plasma concentration of the inflammatory biomarkers, however, there was a significant increase in the expression of Apo A1 (p = 0.011), ELN (p = 0.017) and IL4 (p = 0.037) genes.

Conclusions: The BALANCE Program, the qualitative-quantitative food plan composed of Brazilian usual foods, did not reduce the concentration of inflammatory biomarkers, but increased in total peripheral blood cells the expression of genes involved in reducing the risk of cardiometabolic in obese patients, in secondary prevention for cardiovascular disease. The clinical trial is registered at https://clinicaltrials.gov/ and the unique identifier is NCT01620398.

Association between plasma fatty acids and inflammatory markers in patients with and without insulin resistance and in secondary prevention of cardiovascular disease, a cross-sectional study.

Nutr J 2018 02 21;17(1):26. Epub 2018 Feb 21.

Department of Nutrition, School of Public Health, University of São Paulo, São Paulo, Brazil.

Background: Proinflammatory biomarkers levels are increased among patients with cardiovascular disease, and it is known that both the presence of insulin resistance and diet may influence those levels. However, these associations are not well studied among patients with established cardiovascular disease. Our objective is to compare inflammatory biomarker levels among cardiovascular disease secondary prevention patients with and without insulin resistance, and to evaluate if there is any association between plasma fatty acid levels and inflammatory biomarker levels among them.

Methods: In this cross-sectional sub-study from the BALANCE Program Trial, we collected data from 359 patients with established cardiovascular disease. Plasma fatty acids and inflammatory biomarkers (interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12, high sensitive C-reactive protein (hs-CRP), adiponectin, and tumor necrosis factor (TNF)-alpha) were measured. Biomarkers and plasma fatty acid levels of subjects across insulin resistant and not insulin resistant groups were compared, and general linear models were used to examine the association between plasma fatty acids and inflammatory biomarkers.

Results: Subjects with insulin resistance had a higher concentration of hs-CRP (p = 0.002) and IL-6 (p = 0.002) than subjects without insulin resistance. Among subjects without insulin resistance there was a positive association between stearic fatty acid and IL-6 (p = 0.032), and a negative association between alpha-linolenic fatty acid and pro-inflammatory biomarkers (p < 0.05). Among those with insulin resistance there was a positive association between monounsaturated fatty acids and arachidonic fatty acid and adiponectin (p < 0.05), and a negative association between monounsaturated and polyunsaturated fatty acids and pro-inflammatory biomarkers (p < 0.05), as well as a negative association between polyunsaturated fatty acids and adiponectin (p < 0.05). Our study has not found any association between hs-CRP and plasma fatty acids.

Conclusions: Subjects in secondary prevention for cardiovascular disease with insulin resistance have a higher concentration of hs-CRP and IL-6 than individuals without insulin resistance, and these inflammatory biomarkers are positively associated with saturated fatty acids and negatively associated with unsaturated fatty acids.

Screening tool for oropharyngeal dysphagia in stroke - Part I: evidence of validity based on the content and response processes.

Codas 2017 Aug 17;29(4):e20170009. Epub 2017 Aug 17.

Universidade Estadual Paulista - UNESP - Marília (SP), Brasil.

Purpose: The aim of the present study was to identify the evidence of validity based on the content and response process of the Rastreamento de Disfagia Orofaríngea no Acidente Vascular Encefálico (RADAVE; "Screening Tool for Oropharyngeal Dysphagia in Stroke").

Methods: The criteria used to elaborate the questions were based on a literature review. A group of judges consisting of 19 different health professionals evaluated the relevance and representativeness of the questions, and the results were analyzed using the Content Validity Index. In order to evidence validity based on the response processes, 23 health professionals administered the screening tool and analyzed the questions using a structured scale and cognitive interview.

Results: The RADAVE structured to be applied in two stages. The first version consisted of 18 questions in stage I and 11 questions in stage II. Eight questions in stage I and four in stage II did not reach the minimum Content Validity Index, requiring reformulation by the authors. The cognitive interview demonstrated some misconceptions. New adjustments were made and the final version was produced with 12 questions in stage I and six questions in stage II.

Conclusion: It was possible to develop a screening tool for dysphagia in stroke with adequate evidence of validity based on content and response processes. Both validity evidences obtained so far allowed to adjust the screening tool in relation to its construct. The next studies will analyze the other evidences of validity and the measures of accuracy.

Association between polyunsaturated fatty acids and inflammatory markers in patients in secondary prevention of cardiovascular disease.

Nutrition 2017 May 28;37:30-36. Epub 2016 Dec 28.

Department of Nutrition, School of Public Health, University of São Paulo, São Paulo, Brazil. Electronic address:

Objective: The aim of this study was to assess the association between polyunsaturated fatty acids (PUFAs) and inflammatory biomarkers among patients in secondary prevention of cardiovascular disease (CVD).

Methods: In this cross-sectional substudy from BALANCE Program Trial, we have collected data from 364 patients with established CVD. Twenty-four-hour dietary recalls and plasma FA concentrations were analyzed to estimate the FA intake. Inflammatory biomarkers measurement consisted of interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12, C-reactive protein, adiponectin, and tumor necrosis factor-α. After log-transformation of inflammatory biomarkers, multivariate-adjusted general linear model was used to examine the effect of FA intake. The association was adjusted for body mass index, waist circumference, energy, smoking status, age, total cholesterol, low-density lipoprotein cholesterol, physical activity, and calcium channel blockers.

Results: PUFAs were inversely associated with C-reactive protein levels (P = 0.006) and with IL-1 β. The increase of 1 g/1000 kcal in PUFAs, omega-3, and omega-6 reduces, on average, 6%, 48%, and 8% respectively, the mean concentration of IL-1 β.

Conclusion: Omega-3 and omega-6 FA intakes are inversely associated with inflammatory biomarkers among CVD patients. Additional studies on omega-3 and omega-6 intake in relation to inflammatory biomarkers in patients in secondary prevention of CVD are needed, particularly regarding dietary patterns that are rich in some sources of PUFA.
