ABSTRACT
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.

ABSTRACT
OBJECTIVE: To evaluate the association of glycemic-control formulae (GCF) with measurements of glycemic control and clinical outcomes compared to standard enteral formulae (SF) in critically ill patients. DATA SOURCES: MEDLINE, EMBASE, Scopus and the Cochrane Central Register of Controlled Trials were searched from inception up to January, 2021. STUDY SELECTION: RCTs that assessed the effects of GCF relative to SF in adult critically ill patients. DATA EXTRACTION: Measurements of glycemic control were the primary outcomes. Secondary outcomes included insulin requirements, mechanical ventilation (MV), length of intensive care unit (ICU) stay and mortality. Two authors independently extracted data and assessed risk of bias using the Cochrane's RoB 2 tool and the GRADE approach was used to assess the quality of evidence. DATA SYNTHESIS: Ten studies (12 reports, 685 patients) were included. The use of GCFs was associated with lower blood glucose (WMD, -16.06 mg/dL; 95% CI -23.48 to -8.63; I2 = 47%) and lower daily administered insulin (WMD, -7.20 IU; 95% CI -13.92 to -0.48; I2 = 53%). Glycemic variability, measured by the coefficient of variation, was also associated with the use of GCFs (WMD, -6.84%; 95% CI, -13.57 to -0.11; I2 = 95%). In contrast, analyses for length of ICU stay (WMD, -0.12, 95% CI -1.77 to 1.52; I2 = 0%), duration of MV (WMD, -0.34 days; 95% CI, -1.72 to 1.04; I2 = 0%) and mortality (RR, 1.13; 95% CI 0.82 to 1.56; I2 = 0%) were not statistically significant. Quality of evidence ranged from low to very low, and only one study was judged as at low risk of bias. CONCLUSIONS: In this meta-analysis, GCFs were significantly associated with lower insulin requirements and improved glycemic control. Although results for clinical outcomes were not statistically significant, there is insufficient evidence to confirm or exclude important differences due to serious imprecision in the effect estimates and overall low quality of evidence. The effects of GCFs on clinical outcomes require confirmation in larger randomized trials.

BACKGROUND AND OBJECTIVE: Recent studies have related the consumption of ultra-processed foods with the development of cardiovascular diseases and have considered this relation with excessive sodium intake. While Brazilian studies have analysed that this consumption may have no direct relationship with the processing, but rather with the addition of salt. The purpose of this study is to investigate the contribution of the consumption of processed products in the daily intake of sodium ingestion by atherosclerotic disease patients. METHODS: A sub study, conducted with data from 630 cardiopathic patients who take part in "Effect of Brazilian Cardioprotective Food Program study on the reduction of events and risk factors in secondary prevention of cardiovascular disease part". Food was classified as: unprocessed or minimally processed foods, processed culinary ingredients, processed foods, ultra-processed food and beverages. Twenty-four-hour food recall (R24h) was collected from patients, and the estimation of total calories and sodium intake were calculated, as well as the percentage of sodium contribution according to the categories already mentioned. For the adequacy ratio analysis, the daily values of sodium intake were used to compared to the recommendations of the World Health Organization (<2000 mg / day). RESULTS: The average sodium intake was 1970.87 mg for women and 2642.86 mg for men, being higher for males' patients aged 60-79. It was observed that 64% of the studied population demonstrated sodium intake > 2000 mg. When considered levels > 3001 mg, a higher incidence of consumption was observed in the male group. Only 21.1% were intaking sodium within the recommended amount. Industrialized foods contributed to 33% of the mineral intake. CONCLUSION: These findings have demonstrated that the majority of the studied patients exceeded the dietary sodium recommendation. It has also indicated that patient's male, have presented increased consumption of the mineral. Consequently, warning for the necessity of greater investments in the nutritional re-education of these patients.
