RESUMEN
PURPOSE: Nut-enriched diets are related to improve lipid and inflammatory biomarkers in meta-analyses in the context of primary cardiovascular prevention. However, primary studies on secondary cardiovascular prevention are scarce and controversial. This systematic review and meta-analysis aimed to evaluate the effect of nut supplementation on lipid and inflammatory profiles in individuals with atherosclerotic cardiovascular disease, and the frequency of adverse events. METHODS: Six databases were used for research: PubMed, EMBASE, BVS, Cochrane Library, Web of Science, and ClinicalTrials.gov, until February 2023, with no language restrictions. We performed random-effects meta-analyses to compare nut-enriched diets vs. control diets for pre-post intervention changes. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system assessed the evidence's certainty. RESULTS: From the 5187 records identified, eight publications containing data referring to five randomized clinical trials involving 439 participants were included in the final analyses. The nuts evaluated were almonds, pecans, Brazil nuts, and mixed nuts, with doses ranging between 5 g and 85 g (median: 30 g/day). The intervention time varied between 6 and 12 weeks. Compared to nut-free diets, nut intake did not have a statistically significant effect on lipid profile biomarkers, except on the atherogenic index (MD: -0.32 [95% CI -0.58 to -0.06], I2 = 0% - moderate certainty of the evidence). Similarly, there was no effect of nuts on inflammatory profile biomarkers. It was not possible to aggregate data on adverse events. CONCLUSIONS: Nut supplementation did not change lipid and inflammatory profiles in the secondary cardiovascular prevention setting.
RESUMEN
BACKGROUND AND AIM: Increased consumption of ultra-processed foods has been linked to both mortality and cardiovascular risk. Copeptin levels may serve as potential risk markers for cardiovascular death and events. This cross-sectional analysis seeks to assess the potential correlation between the intake of ultra-processed foods and copeptin levels in outpatients diagnosed with type 2 diabetes, based on estimates of cardiovascular risk. METHODS AND RESULTS: Outpatients underwent clinical and nutritional assessments. Dietary information was gathered using a validated quantitative food frequency questionnaire, and the consumption of all foods, beverages, and food products was assessed according to the NOVA food classification system. Fasting plasma-EDTA samples were collected and preserved at -80 °C. Plasma copeptin measurements were analyzed using an enzyme-linked immunosorbent assay based on the competition principle. Participants were categorized into two groups: high risk and very high risk, based on cardiovascular risk calculated by the HEARTS calculator. A total of 190 participants were included in the evaluation, with an average age of 60 ± 9 years, glycated hemoglobin of 8.4 ± 1.4%, and a diabetes duration of 11 (5-19) years. Patients at a very high cardiovascular risk exhibited higher plasma copeptin levels compared to those at high cardiovascular risk. Notably, 92.1% of patients reported consuming more than 10% of total energy intake from ultra-processed foods, although this proportion did not differ between the two groups. CONCLUSION: This patient sample reported elevated consumption of ultra-processed foods; nevertheless, the correlation between ultra-processed foods and plasma copeptin has not been substantiated.

OBJECTIVE: The objective was to evaluate the psychometric properties of the Mindful Eating Questionnaire (MEQ) in Brazilian subjects with type 2 diabetes mellitus (T2DM) and validate a Brazilian version of the MEQ for adults with T2DM (MEQ-DM). METHODOLOGY: Baseline data from the multicentre Nutritional Strategy for Glycaemic Control in Patients with Type 2 Diabetes Mellitus (NUGLIC) trial were used. Construct validity was assessed using exploratory factor analysis (EFA). The root mean square error of approximation (RMSEA), comparative fit index (CFI) and TuckerâLewis index (TLI) fit indices indicated the adequacy of the model. The reliability of the questionnaire was evaluated considering the different factor loadings. Criterion validity was tested by correlating the MEQ-DM with sociodemographic variables, body mass index (BMI) and physical activity levels. RESULTS: A total of 370 participants were included, who were mostly female (60.8 %) and had a median age of 61 (54-67) years. The EFA results supported the two-factor structure of the 25-item MEQ-DM: disinhibition and awareness. The results of the fit indices (RMSEA = 0.04; CFI = 0.95 and TLI = 0.94) and composite reliability (disinhibition = 0.84 and awareness = 0.81) were consistent. The criterion validity analysis indicated a significant association between MEQ-DM scores and age, sex, civil status, education level, BMI and physical activity (p < 0.05). CONCLUSION: When explored with Brazilian adults with T2DM, the MEQ-DM presented a factorial model with two dimensions: disinhibition and awareness. This model must be confirmed in future studies with Brazilians with T2DM.

BACKGROUND: Hydroxychloroquine and azithromycin have been used to treat patients with coronavirus disease 2019 (Covid-19). However, evidence on the safety and efficacy of these therapies is limited. METHODS: We conducted a multicenter, randomized, open-label, three-group, controlled trial involving hospitalized patients with suspected or confirmed Covid-19 who were receiving either no supplemental oxygen or a maximum of 4 liters per minute of supplemental oxygen. Patients were randomly assigned in a 1:1:1 ratio to receive standard care, standard care plus hydroxychloroquine at a dose of 400 mg twice daily, or standard care plus hydroxychloroquine at a dose of 400 mg twice daily plus azithromycin at a dose of 500 mg once daily for 7 days. The primary outcome was clinical status at 15 days as assessed with the use of a seven-level ordinal scale (with levels ranging from one to seven and higher scores indicating a worse condition) in the modified intention-to-treat population (patients with a confirmed diagnosis of Covid-19). Safety was also assessed. RESULTS: A total of 667 patients underwent randomization; 504 patients had confirmed Covid-19 and were included in the modified intention-to-treat analysis. As compared with standard care, the proportional odds of having a higher score on the seven-point ordinal scale at 15 days was not affected by either hydroxychloroquine alone (odds ratio, 1.21; 95% confidence interval [CI], 0.69 to 2.11; P = 1.00) or hydroxychloroquine plus azithromycin (odds ratio, 0.99; 95% CI, 0.57 to 1.73; P = 1.00). Prolongation of the corrected QT interval and elevation of liver-enzyme levels were more frequent in patients receiving hydroxychloroquine, alone or with azithromycin, than in those who were not receiving either agent. CONCLUSIONS: Among patients hospitalized with mild-to-moderate Covid-19, the use of hydroxychloroquine, alone or with azithromycin, did not improve clinical status at 15 days as compared with standard care.

BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Consumption of food in its natural form has an inverse relationship with cardiometabolic risk factors; however, the relationship between consumption of unprocessed or minimally processed foods and the presence of cardiovascular diseases (CVD) remains unclear in individuals receiving secondary care for CVD. Thus, we aimed to evaluate the association between the consumption of unprocessed or minimally processed foods and the presence of CVD and cardiometabolic risk factors in individuals with established CVD. Baseline data from 2357 participants in a Brazilian multicentre study showed that the consumption of unprocessed or minimally processed foods corresponded to most of the daily caloric intake (69.3%). Furthermore, regression analyses showed that higher consumption of unprocessed or minimally processed foods (>78.0% of caloric intake) was associated with a lower prevalence of elevated waist circumference (WC1; PR: 0.889; CI: 0.822-0.961; WC2; PR: 0.914; CI: 0.873-0.957) and overweight (PR: 0.930; CI: 0.870-0.994), but also was associated with simultaneous occurrence of coronary and peripheral artery disease and stroke (OR: 2.802; CI: 1.241-6.325) when compared with a lower intake (<62.8% of caloric intake). These findings reinforce the importance of nutritional guidance that considers the profile of the target population and the composition and quality of the meals consumed.

The consumption of nuts and extra-virgin olive oil has been associated with suppression of inflammatory pathways that contribute to atherosclerosis, but its role on the modulation of the inflammatory profile in patients with established coronary artery disease (CAD) is unclear. The aim of this study was to evaluate the effects of adding pecan nuts or extra-virgin olive oil to a healthy diet on inflammatory markers in patients with stable CAD. In this randomised clinical trial, 204 patients were enrolled to three study groups: sixty seven to control group (CG: healthy diet), sixty eight to pecan nuts group (PNG: 30 g/d of pecans + healthy diet) and sixty nine to extra-virgin olive oil group (OOG: 30 ml/d of extra-virgin olive oil + healthy diet). High-sensitivity C-reactive protein (hs-CRP, in mg/l), fibrinogen (mg/dl), IL 2, 4, 6, 10 (pg/ml) and interferon-γ (IFN-γ, in pg/ml), IL-6/IL-10, IL-2/IL-4 and IFN-/γIL-4 ratios were evaluated at baseline and after the follow-up (12 weeks). As main results, after adjustment for sex, statin used and relative body weight variation, there were no differences between groups regarding inflammatory markers at the end of the study. IL-6 levels (primary outcome) were reduced in 12 weeks when compared with baseline in all study groups (CG: difference: -0·593 (se = 0·159) pg/dL; PNG: difference: -0·335 (se = 0·143) pg/dl; OOG: IL-6 difference: -0·325 (se = 0·143) pg/dl). In conclusion, there was no significant effect of including pecan nuts or extra virgin olive oil to a healthy diet on inflammatory markers in individuals with CAD.

This study aimed to evaluate the association between legume intake and blood pressure, as well as the mediating role of cardiometabolic risk factors in patients in secondary cardiovascular prevention. Socio-demographic, anthropometric, clinical and food intake data were collected from the baseline of the multicentre study Brazilian Cardioprotective Nutritional Program Trial - BALANCE (RCT: NCT01620398). The relationships between variables were explored through path analysis. In total, 2247 individuals with a median age of 63·0 (45-91) years, 58·8 % (n 1321) male and 96·5 % (n 2168) with diagnosis of hypertension were included. Negative associations were observed between histidine intake and systolic blood pressure (SBP) (standardised coefficient (SC) = -0·057; P = 0·012) and between legume intake and BMI (SC = -0·061; P = 0·006). BMI was positively associated with triglycerides-glucose (TyG) index (SC = 0·173; P < 0·001), SBP (SC = 0·144; P < 0·001) and diastolic blood pressure (DBP) (SC = 0·177; P < 0·001), and TyG index was positively associated with DBP (SC = 0·079; P = 0·001). A negative indirect effect was observed between the intake of legumes, SBP and DBP, mediated by BMI (SC = -0·009; P = 0·011; SC = -0·011; P = 0·010, respectively). In addition, an indirect negative effect was found between the intake of legumes and the DBP, mediated simultaneously by BMI and TyG index (SC = -0·001; P = 0·037). In conclusion, legume intake presented a negative indirect association with blood pressure, mediated by insulin resistance (TyG) and adiposity (BMI) in individuals of secondary care in cardiology.

The consumption of ultra-processed foods (UPF) has been associated with cardiometabolic risk factors. However, there is scarce literature on the association between UPF consumption, cardiovascular events, and cardiometabolic risk factors in subjects undergoing secondary care for cardiovascular diseases (CVD). Thus, we aimed to evaluate the association between UPF consumption, CVD, and cardiometabolic risk factors in subjects with established CVD. Baseline data from 2,357 subjects participating in a Brazilian multicenter study were analysed finding a mean UPF consumption of 18.7% of their energy intake. Higher figures of UPF consumption were founded associated with an increased presence of high waist circumference, overweight, peripheral arterial disease, and with a decreased odds of the simultaneous presence of coronary arterial disease, peripheral arterial diseases, and stroke when comparing among tertiles of UPF contribution to energy intake. These associations were observed when analyzing the whole sample and women but not men. Thus, these findings should help improve strategies for CVD patients in secondary care.

Objective: This study aimed to evaluate the validity of calf circumference (CC) in identifying malnourished patients and patients at nutritional risk and determine the association between CC and clinical outcomes of hospitalized patients.Methods: A prospective cohort study was conducted involving patients admitted to the emergency department of a tertiary hospital in the first 48 hours of admission. Nutritional risk was determined using Nutritional Risk Screening, malnutrition was diagnosed using subjective global assessment, and CC was manually measured. Brazilian cutoff points for CC were used to identify low muscle mass. The outcomes of interest were length of emergency care and hospital stay, occurrence of infection, and death, besides nutritional risk and malnutrition.Results: In total, 528 patients (52.76 ± 16.18 years; 54.6% females) were followed up for 9.0 (3.0-19.0) days; 39.6% of them had reduced CC values. The accuracy of CC in identifying patients at nutritional risk and malnourished patients was 67.7% and 54.1%, respectively. The cutoff value of 36.5 cm was highly accurate in identifying nutritional risk [AUC-ROC curve = 0.764 (95% CI: 0.704-0.825) for men, and AUC-ROC curve = 0.716 (95% CI: 0.659-0.774) for women]. Patients with low CC had a 1.59-fold (95% CI: 1.07-2.36) greater likelihood of a long hospital stay than patients with normal CC.Conclusions: Low CC values have satisfactory validity in identifying nutritional risk and are associated with long hospital stay.

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 (nâ¯=â¯1,266) or the control group (nâ¯=â¯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⯱â¯8.4 vs 24.7⯱â¯8.6, Pâ¯<â¯.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; Pâ¯=â¯.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.

The aim of this study was to investigate whether carbohydrate mouth rinse (CMR) improves physical performance of cyclists during a 30-km time trial test and its influence on water balance compared to other strategies of fluid intake. Eleven recreationally trained male cyclists completed a 30 km time trial cycle ergometer under three experimental interventions: (a) CMR, (b) drinking to replace all weight loss (DWL), and (c) drinking "ad libitum" (DAL). Time to complete the 30 km time trial, heart rate, average power, velocity, weight loss, urine color, urine density and pH were evaluated. Statistical analysis was performed using repeated measures analysis of variance (RM-ANOVA) and generalized estimating equations (GEE) with Bonferroni adjustment (p < 0.05). Time to complete the 30 km time trial was similar among CMR 54.5 ± 2.9 min, DWL 53.6 ± 3.9 min and DAL 54.5 ± 2.5 min (p = 0.13). CMR (1.7 ± 0.4%) elicited similar water loss compared to the DAL (1.4 ± 0.6%) intervention, but it was higher than the DWL intervention (0.6 ± 0.6%) (p < 0.01). CMR did not improve the performance of recreationally trained cyclists in a 30 km time trial test compared to other fluid intake strategies. Furthermore, CMR causes higher water loss compared to DWL intervention.

Dietary modifications are essential strategies for cardiovascular disease prevention. However, studies are needed to investigate the diet quality of individuals undergoing secondary prevention in cardiology and who received dietary intervention based on cardiovascular disease management. We prospectively evaluated the diet quality in the Brazilian Cardioprotective Nutritional Program Trial (BALANCE Program Trial). We hypothesized that the BALANCE Program could improve patients' dietary pattern according to different indices of diet quality such as the Dietary Inflammatory Index (DII); the dietary total antioxidant capacity; overall, healthful, and unhealthful Plant-Based Diet Index (PDI, hPDI, and uPDI, respectively); and modified Alternative Healthy Eating Index (mAHEI). This multicenter randomized, controlled trial included patients aged ≥45 years randomly assigned to either the experimental or control group. Data from 2185 participants at baseline and after 12, 24, 36, and 48 months showed that the intervention group (n = 1077) had lower mean values of DII and higher dietary total antioxidant capacity, PDI, hPDI, and mAHEI than the control group. The results also showed differences between the follow-up times for DII, hPDI, and uPDI (48 months vs baseline) and for PDI and mAHEI (24 months vs baseline), regardless of group. The interaction analysis demonstrated that the intervention group showed better results than the control group at 12, 24, 36, and 48 months for the DII and at months 12, 36, and 48 for the mAHEI. Our results provide prospective evidence that the BALANCE Program improved the diet quality in those in secondary cardiovascular prevention according to different indices, with the intervention group showing better results than the control group.

BACKGROUND: We conducted a systematic review and meta-analysis to examine the effect of dietary intake of cocoa on anthropometric measurements, lipid and glycemic profiles, and blood pressure levels in adults, with and without comorbidities. METHODS: The databases used were MEDLINE (PubMed), EMBASE, Web of Science, Cochrane, LILACS, and SciELO. The eligible studies were randomized clinical trials (RCTs) involving adults undergoing cocoa consumption (cocoa extract or ≥70% cocoa dark chocolate) for ≥4 weeks that evaluated at least one of the following markers: body weight, body mass index (BMI), waist/abdominal circumference, total cholesterol, LDL-c, triglycerides, HDL-c, blood glucose, glycated hemoglobin (HbA1c), and systolic and diastolic blood pressure (SBP/DBP). RESULTS: Thirty-one studies were included, totaling 1986 participants. Cocoa consumption showed no effects on body weight, BMI, waist circumference, triglycerides, HDL-c and HbA1c. Yet, there was a reduction in total cholesterol (-8.35 mg/dL, 95% CI -14.01; -2.69 mg/dL), LDL-c (-9.47 mg/dL, 95% CI -13.75; -5.20 mg/dL), fasting blood glucose (-4.91 mg/dL, 95% CI -8.29; -1.52 mg/dL), SBP (-2.52 mmHg, 95% CI -4.17; -0.88 mmHg), and DBP (-1.58 mmHg, 95% CI -2.54; -0.62 mmHg). CONCLUSIONS: The consumption of cocoa showed protective effects on major cardiometabolic risk markers that have a clinical impact in terms of cardiovascular risk reduction.

OBJECTIVE: The Wheel of Cardiovascular Health Diet was recently elaborated based on current nutritional recommendations for healthy eating and was made for person-centered nutritional counseling, thus it may be an interesting tool to improve food awareness. However, its validity is yet to be tested. We hypothesized that the self-perception of patients diagnosed with chronic diseases, evaluated by the Wheel of Cardiovascular Health Diet, is satisfactory in assessing the quality of their diets, compared with the Healthy Eating Index-2020. METHODS: This is a cross-sectional analysis of adults with uncontrolled hypertension or type 2 diabetes. The patients answered the Wheel of Cardiovascular Health Diet, and then, based on the food frequency questionnaire, we analyzed the Healthy Eating Index-2020. RESULTS: A total of 330 patients were included in the study: 91.5% had hypertension, 58.5% had type 2 diabetes, and the median age was 58 (50-65) years. The mean difference observed between the percentage of the graphic area assessed by the patients' self-perception from the Wheel of Cardiovascular Health Diet and Healthy Eating Index-2020 was -10.0% (95%CI -35.3 to 15.3), and a moderate correlation was observed. Linear Regression models showed that a 10-point increase in patients' self-perception in the Wheel of Cardiovascular Health Diet is associated with a 2.9% increase (95%CI 2.08 to 3.70) in the diet quality by the Healthy Eating Index-2020 and is associated with lower BMI values: ß = -0.42 kg/m2 (95%CI -0.83 to -0.01). CONCLUSION: The Wheel of Cardiovascular Health Diet performed satisfactorily regarding validity and reliability by BMI and was associated with higher overall dietary quality, with the Healthy Eating Index-2020 as a relative reference.

BACKGROUND: Achieving nutritional goals established by scientific societies is a constant challenge and not always achieved. OBJECTIVE: To investigate the dietary adequacy of individuals with cardiovascular disease (CVD), participants in the Cardioprotective Brazilian Food Program residing in the Northeast region of Brazil, according to the recommendations of the Brazilian Society of Cardiology (SBC). METHODS: Cross-sectional analysis with data from the study implementing the Brazilian Cardioprotective Diet (DICA BR), which evaluated individuals with CVD treated in specialized cardiovascular health centers in eight states in the Northeast region. Food consumption was obtained by 24-hour dietary records and dietary adequacy followed SBC recommendations. Values of p < 0.05 were considered significant. RESULTS: 647 patients were studied, with a mean (standard deviation) age of 63.1 (9.4) years, 50.2% of whom were female. When evaluating food intake, a low adequacy of carbohydrates (52.3%), proteins (70.9%), lipids (38.8%), and fiber (22.4%) was observed. It was observed that the majority of women consumed a low-protein diet (59.2%) and the elderly had a greater inadequacy in carbohydrate consumption (52.6%). Regarding sodium intake, men had a higher intake (72.9%), while the elderly showed a 13% reduction. Furthermore, it was shown that men ate more fiber (28.1%) and individuals with higher education had a high consumption of saturated fatty acids (70.5%). CONCLUSIONS: Most individuals did not achieve the recommended dietary therapy goals for secondary cardiovascular prevention. The findings of the present study reinforce the need to implement structured strategies to encourage healthy eating habits in these individuals.
FUNDAMENTO: Alcançar as metas nutricionais estabelecidas pelas sociedades científicas é um desafio constante e nem sempre alcançado. OBJETIVO: Investigar a adequação alimentar de indivíduos com doença cardiovascular (DCV), participantes do Programa Alimentar Brasileiro Cardioprotetor residentes da região Nordeste do Brasil, segundo as recomendações da Sociedade Brasileira de Cardiologia (SBC). MÉTODOS: Análise transversal com dados do estudo de implementação da Dieta Cardioprotetora Brasileira (DICA BR) que avaliou indivíduos com DCV, atendidos em centros especializados em saúde cardiovascular em oito estados do Nordeste. O consumo alimentar foi obtido por recordatório alimentar de 24 horas e a adequação da dieta seguiu as recomendações da SBC. Foram considerados significantes valores de p < 0,05. RESULTADOS: Foram estudados 647 pacientes, com média (desvio padrão) de idade de 63,1 (9,4) anos, sendo 50,2% do sexo feminino. Na avaliação da ingestão alimentar, observou-se baixa adequação de carboidratos (52,3%), proteínas (70,9%), lipídios (38,8%) e fibras (22,4%). Observou-se que a maioria das mulheres consumia dieta hipoproteica (59,2%) e idosos tinham maior inadequação no consumo de carboidratos (52,6%). Em relação a ingestão de sódio, os homens apresentaram maior ingestão (72,9%), enquanto os idosos apresentaram redução de 13%. Além disso, foi demonstrado que os homens ingeriam mais fibras (28,1%) e indivíduos com maior escolaridade tinham um consumo elevado de ácidos graxos saturados (70,5%). CONCLUSÕES: A maioria dos indivíduos não alcançou as metas dietoterápicas preconizadas para prevenção cardiovascular secundária. Os achados do presente estudo reforçam a necessidade de implementação de estratégias estruturadas, a fim de estimular hábitos alimentares saudáveis nesses indivíduos.

CONTEXT: Nut-enriched diets have a positive impact on cardiovascular risk factors, such as body mass, blood pressure, and fasting blood glucose. However, studies in individuals undergoing secondary cardiovascular prevention show controversial results. OBJECTIVE: This systematic review with meta-analysis assessed the effect of nut supplementation on anthropometric, glycemic, and blood pressure indices in patients with atherosclerotic cardiovascular disease, as well as the frequency of adverse events. DATA SOURCES: Six databases were used for the search-PubMed, Cochrane Library, EMBASE, BVS (Biblioteca Virtual da Saude), Web of Science, and ClinicalTrials.gov-until February 2023, with no language restrictions. DATA EXTRACTION: The Cochrane Handbook for Systematic Reviews of Interventions methodology and the PICOS (Population, Intervention, Comparison, Outcome, Setting/design) strategy were used. Seven independent reviewers were involved in data extraction and resolution of disagreements. Certainty of the evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. DATA ANALYSIS: From 5187 records identified, 6 publications containing data referring to 5 randomized clinical trials (n = 436) were included in the final analyses. The nuts evaluated were almonds, pecans, Brazil nuts, and mixed nuts, with portions that varied between 5 g and 85 g (median: 30 g/day). The intervention period varied between 6 and 12 weeks. The nuts had no effect on fasting glucose and anthropometric indices, although the certainty of the evidence for most of these outcomes was low or very low. They also had no effect on systolic (mean difference [MD]: -1.16 mmHg [95% CI, -5.68 to 3.35], I2 = 0%-moderate certainty of evidence) or diastolic (MD: 0.10 mmHg [95% CI, -2.30 to 2.51], I2 = 0%-high certainty of evidence) blood pressure. It was not possible to aggregate data on adverse events. CONCLUSION: Nut supplementation had no effect on blood pressure, fasting glucose, or anthropometric profile in the context of atherosclerotic cardiovascular disease.

RESUMEN
OBJECTIVE: To evaluate the effectiveness of a nutritional strategy based on two components and adapted for the public health system on blood pressure, cardiometabolic features, self-care, qualify of life and diet quality in individuals with hypertension. METHODS: NUPRESS was an open-label, parallel-group, superiority randomized controlled clinical trial in which participants at least 21âyears with hypertension and poorly controlled blood pressure were randomly assigned (1â:â1 allocation ratio) to either an individualized dietary prescription according to nutritional guidelines (control group, n â=â205); or a two-component nutrition strategy, including a goal-directed nutritional counseling and mindfulness techniques (NUPRESS [intervention] group, n â=â205). Primary outcomes were SBP (mmHg) after 24 weeks of follow up and blood pressure control, defined as either having SBP more than 140âmmHg at baseline and achieving 140âmmHg or less after follow-up or having SBP 140âmmHg or less at baseline and reducing the frequency of antihypertensive drugs in use after follow-up. RESULTS: In total, 410 participants were randomized and submitted to an intention-to-treat analysis regarding primary outcomes. Both groups decreased blood pressure, but after adjusting for baseline values, there was no significant difference between them on SBP [intervention-control difference: -0.03 (-3.01; 2.94); P â=â0.98] nor blood pressure control [odds ratio 1.27 (0.82; 1.97); P â=â0.28]. No differences between groups were also detected regarding secondary and tertiary outcomes. CONCLUSION: There was no difference between a two-component nutritional strategy and an established dietary intervention on blood pressure in participants with hypertension.

BACKGROUND: Adhering to a diet adequate in macronutrients is crucial for the secondary prevention of cardiovascular diseases. OBJECTIVE: To assess the prevalence of adherence to recommendations for the consumption of dietary fatty acids for the prevention and treatment of cardiovascular diseases and to estimate whether the presence of certain cardiovascular risk factors would be associated with adherence. METHODS: Cross-sectional study using baseline data from 2,358 participants included in the "Brazilian Cardioprotective Nutritional Program Trial". Dietary intake and cardiovascular risk factors were assessed. Adequate intake of polyunsaturated fatty acids (PUFA) was considered as ≥10% of total daily energy intake; for monounsaturated fatty acids (MUFA), 20%; and for saturated fatty acids (SFA), <7% according to the Brazilian Society of Cardiology. A significance level of 5% was considered in the statistical analysis. RESULTS: No participant adhered to all recommendations simultaneously, and more than half (1,482 [62.9%]) did not adhere to any recommendation. Adherence exclusively to the SFA recommendation was the most prevalent, fulfilled by 659 (28%) participants, followed by adherence exclusively to the PUFA (178 [7.6%]) and MUFA (5 [0.2%]) recommendations. There was no association between the number of comorbidities and adherence to nutritional recommendations (p = 0.269). Participants from the Brazilian Northeast region showed a higher proportion of adherence to SFA consumption recommendations (38.42%) and lower adherence to PUFA intake (3.52%) (p <0.001) compared to other regions. CONCLUSIONS: Among the evaluated sample, there was low adherence to nutritional recommendations for dietary fatty acid consumption.
FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.

BACKGROUND: Genetic variants of the FTO gene rs9939609 A/T and the MC4R gene rs17782313 C/T have been associated with obesity. Individuals with mutations in MC4R gene have lower blood pressure (BP), independently of obesity. This study aimed to investigate the association of FTO rs9939609 and MC4R rs17782313 with anthropometric indexes, BP, and type 2 diabetes mellitus among hypertensive patients. METHODS: We genotyped 217 individuals (86 men and 131 women) with hypertension (systolic or diastolic BP ≥ 140/90 mmHg or using antihypertensive drugs). Diabetes mellitus was diagnosed according to the American Diabetes Association criteria. Waist and neck circumferences (cm), Body Adiposity Index (BAI,%), Lipid Accumulation Product Index (LAP, cm.mmol.l) and body mass index (BMI, kg/m²) were analyzed using analysis of covariance or modified Poisson's regression. RESULTS: Rare allele frequencies were 0.40 for A for FTO rs9939609 and 0.18 for C for MC4R rs17782313. A positive association of FTO rs9939609 and MC4R rs17782313 with BMI was observed in the overall sample. Among men and women, neck circumference was associated with the FTO genotype and, for women, MC4R genotype. In contrast, in men we found a negative association of MC4R rs17782313 with diastolic BP (TT 90.1 ±12.2, TC/CC 83.2 ±12.1; P = 0.03) and borderline association for systolic BP after controlling for age and BMI. CONCLUSIONS: Common genetic variants of FTO rs9939609 have positive associations with BMI and neck circumference and MC4R rs17782313 in women, but a negative association with diastolic and mean blood pressure in men with hypertension.
