Background & Aims: To evaluate the effect of the Brazilian Cardioprotective Diet Program (BALANCE Program) on inflammatory biomarkers, involved in the pathophysiology of the atherosclerosis, on inflammatory biomarkers, cardiovascular risk factors, and on plasma fatty acids in cardiovascular disease secondary prevention patients.

Methods: In this substudy of the BALANCE Program randomized clinical trial, a total of 369 patients aged 45 years or older, who have experienced cardiovascular disease in the previous 10 years, were included. These patients were randomized into two groups and followed up for six months: BALANCE Program group and control group (conventional nutrition advice). In the initial and six-month final visits, anthropometry (body weight, height and waist circumference), food intake evaluation by 24-h dietary recall, plasma inflammatory biomarkers (IL-6, IL-8, IL-10, IL-12, tumor necrosis factor-α, adiponectin, and C-reactive protein levels), blood pressure, glycemia, insulinemia, lipid profile, and plasma fatty acids levels were evaluated.

Results: The BALANCE Program group showed increased plasma alpha-linolenic acid levels (P = 0.008), reduction in waist circumference (P = 0.049) and BMI (P = 0.032). No difference was observed among plasma inflammatory biomarkers and clinical data.

Conclusion: After six months of follow-up, BALANCE Program led to a significant reduction on BMI and waist circumference in individuals in secondary prevention for cardiovascular disease. Although plasmatic alpha-linolenic acid has increased, there was no impact on plasma inflammatory biomarkers.

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial.

Am Heart J 2019 09 21;215:187-197. Epub 2019 Jun 21.

Hospital Universitário Pedro Ernesto, Rio de Janeiro-RJ, Brazil.

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD.

Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels.

Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P < .01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P = .15). Secondary end points did not differ between groups after follow-up.

Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death.

Effects of oral supplementation with probiotics or synbiotics in overweight and obese adults: a systematic review and meta-analyses of randomized trials.

Nutr Rev 2019 06;77(6):430-450

Research Institute at Hospital do Coração, São Paulo, Brazil.

Context: Recent evidence suggests that modulation of the gut microbiota may contribute to body weight control.

Objective: This systematic review aimed to assess the effects of oral supplementation with probiotics or synbiotics on body weight, body mass index (BMI), and waist circumference in overweight and obese adults (BMI ≥ 25 kg/m2).

Data Sources: Five electronic databases-PubMed, Embase, Cochrane Library/CENTRAL, LILACS, and Web of Science-were searched from inception to August 2017. No language restrictions were applied.

Study Selection: Randomized and quasi-randomized parallel trials that assessed the effects of oral supplementation with probiotics or synbiotics vs any other intervention but bariatric surgery or fecal transplantation in overweight or obese adults were selected.

Data Extraction: Three teams of 2 authors independently assessed risk of bias and extracted data from the included trials. Data were pooled using inverse-variance random-effects meta-analyses. The quality of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system.

Results: Nineteen randomized trials (28 publications, 1412 participants) were included. There were no differences in mean body weight change [mean difference (MD), -0.54 kg; 95%CI, -1.09 to 0.01; I2 = 0%; moderate quality of evidence) or mean BMI change (MD, -0.19 kg/m2; 95%CI, -0.43 to 0.04; I2 = 51%; low quality of evidence) between groups who received probiotics or synbiotics and control groups. Oral supplementation with probiotics or synbiotics reduced mean waist circumference compared with control (MD, -0.82 cm; 95%CI, -1.43 to -0.21; I2 = 46%; low quality of evidence).

Conclusions: The findings suggest that oral supplementation with probiotics or synbiotics has a small effect to reduce waist circumference but no effect on body weight or BMI, although the quality of evidence is low to moderate. Therefore, the current evidence is not definitive. Large-scale trials are needed and may help to better inform clinical practice.
