Adequacy of Fatty Acids Consumption Among Individuals in Secondary Cardiovascular Prevention. / Adequação do Consumo de Ácidos Graxos entre Pacientes em Prevenção Cardiovascular Secundária.

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.

Palm density and grazing effects on plant communities: implications for livestock management in a Butia palm grove.

Some grasslands in ecotones with forests tend to be encroached by woody species, because of changes in climate and land use. Such structural changes in vegetation can be facilitated when the grassland community presents an autochthonous arboreal component, like Butia palms. We aim to identify the responses of taxonomic and functional diversity on grassland community with the occurrence of arborescent/arboreal species (autochthonous and encroaching) to palm density and grazing intensity. The study was conducted in a Butia odorata palm grove under cattle management, in Southern Brazil. To assess the taxonomic and functional composition we performed ordinations analysis with the vegetational data and using path analysis we assessed the causal relationships between variables of interest. Density of Butia odorata and woody plants were strongly positive related, suggesting a facilitation process in the establishment of arborescent plants on the grassland matrix. The abundance of less palatable plants and grazing pressure were inversely related, indicating a selection process induced by higher grazing intensity. We suggest that the grazing intensity management must be based on the autochthonous tree density, applying higher grazing intensity in areas with higher density of encroaching plants, in addition to maintaining other regions conducive to Butia palm regeneration through fallows.

Variations in phase angle and handgrip strength in patients undergoing cardiac surgery: Prospective cohort study.

BACKGROUND: Bioimpedance phase angle (PA) is a measure of cell membrane integrity, whereas handgrip strength (HGS) is an evaluation of functional capacity. Although both are related to the prognosis of patients undergoing cardiac surgery, their changes over time are less known. This study followed variations in PA and HGS for 1 year in these patients, determining associations with clinical outcomes. METHODS: This prospective cohort study included 272 cardiac surgery patients. PA and HGS were measured at six predetermined times. The evaluated outcomes were surgery type; bleeding; time of surgery, cardiopulmonary bypass, aortic cross-clamp, and mechanical ventilation; postoperative (PO) length of stay (LOS) in the intensive care unit (ICU) and hospital; and infections, hospital readmission, reoperation, and mortality. RESULTS: There were reductions in PA and HGS values after surgery, with total recovery beginning at 6 months for PA and 3 months for HGS. In the PA area under the curve (AUC), age, combined surgery, and sex (ß = -9.66, P < 0.001; ß = -252.85, P = 0.005; ß = -216.56, P < 0.001, respectively) were predictors for PA-AUC reduction. Stratified by sex, age (ß = -93.54, P < 0.001) and PO LOS (ß = -46.91, P = 0.003) were predictors for HGS-AUC reduction in women, but only age was a predictor in men (ß = -77.02, P = 0.010). PA and HGS had an effect in hospital LOS and ICU LOS. CONCLUSION: Age, combined surgery, and female sex were predictors of reduced PA-AUC, whereas reduced HGS-AUC was predicted by age in both sexes and PO hospital LOS in women, which suggests that these factors could interfere in prognosis.

Short-Finned Pilot Whale Strandings Associated with Pilot Whale Morbillivirus, Brazil.

Cetacean morbillivirus (CeMV) causes illness and death in cetaceans worldwide; the CeMV strains circulating in the Southern Hemisphere are poorly known. We detected a pilot whale CeMV strain in 3 short-finned pilot whales (Globicephala macrorhynchus) stranded in Brazil during July-October 2020. Our results confirm this virus circulates in this species.

Testosterone Supplementation on Sarcopenia Components in Chronic Patients: A Systematic Review and Meta-Analysis.

BACKGROUND: Sarcopenia is a progressive and generalized skeletal muscle disorder with unfavorable muscle changes throughout life, which can be associated with chronic disease. Testosterone supplementation is emerging as a possible therapy; however, it is still necessary to explore its effectiveness. OBJECTIVES: This systematic review and meta-analysis aimed to evaluate and summarize the evidence related to the effect of testosterone supplementation on sarcopenia components of chronic disease patients. METHODS: We performed a systematic review and meta-analysis with studies that assessed the effect of testosterone supplementation on sarcopenia components of chronic disease patients. Papers were identified using Medical Subject Heading (MeSH) terms, combining "sarcopenia", "muscular atrophy", and "testosterone", searching MEDLINE, EMBASE, and Cochrane Library databases, and also hand searching. RESULTS: The database search resulted in 1602 applicable citations that could be included. Of those, 1560 were removed at the first phase, by reading the title and abstract, and a total of 17 studies were finally included after full-text assessment and manual searches of previous review references. With regard to the effects of testosterone supplementation on sarcopenia components, when taken together, the evaluated studies presented an increase in muscle mass and/or muscle strength, but results for muscle functional capacity were inconsistent. CONCLUSION: Testosterone supplementation increased the muscle mass and muscle strength in chronic disease patients. However, current evidence does not indicate that those patients could benefit from testosterone supplementation in order to improve their muscle function.

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

Background Complex percutaneous coronary intervention (PCI) is associated with higher ischemic risk, which can be mitigated by long-term dual antiplatelet therapy (DAPT). However, concomitant high bleeding risk (HBR) may be present, making it unclear whether short- or long-term DAPT should be prioritized. Objectives This study investigated the effects of ischemic (by PCI complexity) and bleeding (by PRECISE-DAPT [PRE dicting bleeding Complications in patients undergoing stent Implantation and Sub sequent Dual Anti Platelet Therapy] score) risks on clinical outcomes and on the impact of DAPT duration after coronary stenting. Methods Complex PCI was defined as ≥3 stents implanted and/or ≥3 lesions treated, bifurcation stenting and/or stent length >60 mm, and/or chronic total occlusion revascularization. Ischemic and bleeding outcomes in high (≥25) or non-high (<25) PRECISE-DAPT strata were evaluated based on randomly allocated duration of DAPT. Results Among 14,963 patients from 8 randomized trials, 3,118 underwent complex PCI and experienced a higher rate of ischemic, but not bleeding, events. Long-term DAPT in non-HBR patients reduced ischemic events in both complex (absolute risk difference: −3.86%; 95% confidence interval: −7.71 to +0.06) and noncomplex PCI strata (absolute risk difference: −1.14%; 95% confidence interval: −2.26 to −0.02), but not among HBR patients, regardless of complex PCI features. The bleeding risk according to the Thrombolysis In Myocardial Infarction scale was increased by long-term DAPT only in HBR patients, regardless of PCI complexity. Conclusions Patients who underwent complex PCI had a higher risk of ischemic events, but benefitted from long-term DAPT only if HBR features were not present. These data suggested that when concordant, bleeding, more than ischemic risk, should inform decision-making on the duration of DAPT. (AU)

Periodontitis and tooth loss have negative impact on dietary intake: A cross-sectional study with stable coronary artery disease patients.

BACKGROUND: Despite the association between cardiovascular diseases and periodontitis, there are scarce data on the impact of oral health in the dietary intake of patients with coronary artery disease (CAD). The aim of this study was to assess the association between dietary intake with periodontitis and present teeth in individuals with stable CAD. METHODS: This cross-sectional study included 115 patients with stable CAD (76 males, aged 61.0 ± 8.3 years) who were under cardiovascular care in an outpatient clinic for at least 3 months. Dietary intake was recorded applying a food frequency questionnaire previously validated. Periodontal examinations were performed by two calibrated examiners in six sites per tooth from all present teeth. Blood samples were collected to determine serum levels of lipids. Multivariable logistic and linear regression models were fitted to evaluate the association between dietary outcomes and oral health variables. RESULTS: Individuals with periodontitis had significantly higher percentage of total energy intake from fried foods, sweets, and beans, and also had lower consumption of fruits than those without periodontitis. Presence of periodontitis was associated with lower percentage of individuals who reached the nutritional recommendation of monounsaturated fatty acids and higher blood concentration of triglycerides. Having a greater number of present teeth (≥20 teeth) was associated with higher intake of fibers and total calories. CONCLUSION: In patients with stable CAD, the presence of periodontitis and tooth loss were associated with a poor dietary intake of nutrients and healthy foods, which are important for cardiovascular prevention.

Phase angle and mortality: a systematic review.

BACKGROUND/OBJECTIVES: The phase angle, expressed through bioelectrical impedance, has been studied as a prognostic marker in several health conditions. As this issue is still conflicting, the question whether this parameter correlates with mortality in the most diverse clinical situations remains. Therefore, this study aimed to evaluate the relationship between phase angle and mortality through a systematic review of the literature. SUBJECTS/METHODS: This research was conducted in electronic databases (Pubmed, Embase, Cochrane, Lilacs, Scielo, e Scopus), and included studies that had phase angle as a variable of interest and mortality/survival as an outcome. Data were extracted independently by two reviewers and disagreements were assessed by a third reviewer. RESULTS: Forty-eight of 455 papers were assessed and an amount of 42 showed a correlation between phase angle and mortality. CONCLUSIONS: Phase angle seems to be a good indicator for mortality in many clinical situations and can be used in screening individuals prone to this outcome.

Different Dietary Patterns and New-Onset Diabetes Mellitus After Kidney Transplantation: A Cross-Sectional Study.

OBJECTIVE: To verify the association of dietary patterns and dietary components with new-onset diabetes mellitus after transplantation (NODAT). DESIGN: Cross-sectional study. SUBJECTS: Adult kidney transplant recipients, without history of diabetes before transplantation, who received a kidney transplant and were followed up for at least 1 year. One hundred and sixteen subjects recruited between January 2013 and August 2014. Diagnosis of NODAT was established according to the American Diabetes Association criteria for type 2 diabetes. METHODS: Demographic, clinical, and anthropometric data were collected. Dietary intake was assessed by food frequency questionnaire, administered by a registered dietitian. Dietary patterns were identified by cluster analysis. Chi-square test was used to verify the association between dietary patterns and NODAT. Total energy, fiber, and cholesterol intake were calculated. Consumption of macronutrients, carbohydrates, proteins, and fats (total fats and saturated, monounsaturated, polyunsaturated and trans fatty acids), were expressed in percentage of total energy intake. RESULTS: Twenty-eight patients developed NODAT in the follow-up period. They presented higher body mass index and body fat percentage, as well as higher levels of triglycerides and urinary protein/creatinine ratio than the non-NODAT group. Two dietary patterns, I and II, were identified. Pattern II was characterized by higher intake of total, saturated, monounsaturated, and trans fats than pattern I. No association between the dietary patterns and NODAT was identified (P = .905), and there was no difference in the distribution of macronutrients, dietary fiber, and dietary cholesterol between the groups with and without NODAT. CONCLUSION: Posttransplant dietary patterns were not different between patients with and without NODAT. Further larger and prospective studies are needed to evaluate a possible relationship between dietary components and NODAT incidence in kidney transplant recipients.

Short-term Effects of High-Dose Caffeine on Cardiac Arrhythmias in Patients With Heart Failure: A Randomized Clinical Trial.

IMPORTANCE: The presumed proarrhythmic action of caffeine is controversial. Few studies have assessed the effect of high doses of caffeine in patients with heart failure due to left ventricular systolic dysfunction at high risk for ventricular arrhythmias. OBJECTIVE: To compare the effect of high-dose caffeine or placebo on the frequency of supraventricular and ventricular arrhythmias, both at rest and during a symptom-limited exercise test. DESIGN, SETTING, AND PARTICIPANTS: Double-blinded randomized clinical trial with a crossover design conducted at the heart failure and cardiac transplant clinic of a tertiary-care university hospital. The trial included patients with chronic heart failure with moderate-to-severe systolic dysfunction (left ventricular ejection fraction <45%) and New York Heart Association functional class I to III between March 5, 2013, and October 2, 2015. INTERVENTIONS: Caffeine (100 mg) or lactose capsules, in addition to 5 doses of 100 mL decaffeinated coffee at 1-hour intervals, for a total of 500 mg of caffeine or placebo during a 5-hour protocol. After a 1-week washout period, the protocol was repeated. MAIN OUTCOMES AND MEASURES: Number and percentage of ventricular and supraventricular premature beats assessed by continuous electrocardiographic monitoring. RESULTS: We enrolled 51 patients (37 [74%] male; mean [SD] age, 60.6 [10.9] years) with predominantly moderate-to-severe left ventricular systolic dysfunction (mean [SD] left ventricular ejection fraction, 29% [7%]); 31 [61%] had an implantable cardioverter-defibrillator device. No significant differences between the caffeine and placebo groups were observed in the number of ventricular (185 vs 239 beats, respectively; P = .47) and supraventricular premature beats (6 vs 6 beats, respectively; P = .44), as well as in couplets, bigeminal cycles, or nonsustained tachycardia during continuous electrocardiographic monitoring. Exercise test-derived variables, such as ventricular and supraventricular premature beats, duration of exercise, estimated peak oxygen consumption, and heart rate, were not influenced by caffeine ingestion. We observed no increases in ventricular premature beats (91 vs 223 vs 207 beats, respectively) in patients with higher levels of plasma caffeine concentration compared with lower plasma levels (P = .91) or with the placebo group (P = .74). CONCLUSIONS AND RELEVANCE: Acute ingestion of high doses of caffeine did not induce arrhythmias in patients with systolic heart failure and at high risk for ventricular arrhythmias. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02045992.

Effects of metabolic syndrome on kidney transplantation outcomes: a systematic review and meta-analysis.

Metabolic syndrome (MS) has been associated with proteinuria and reduced glomerular filtration rate. Immunosuppressive agents increase the incidence of traditional risk factors for cardiovascular disease (CVD) and have known effects on MS components after kidney transplantation. The purpose of this meta-analysis was to evaluate the impact of MS on relevant outcomes after kidney transplantation. MEDLINE, EMBASE, and Cochrane Library were searched up to November 7, 2015. Papers that compared patients with and without MS and assessed one of the following outcomes, graft loss, death by cardiovascular disease, and all-cause mortality, were included. Of 585 studies identified, five studies including 1269 patients were evaluated. MS was identified as a risk factor for graft loss [relative risk, 3.06; 95% confidence interval (CI), 2.17, 4.32; I² = 0%; P heterogeneity = 0.72] and death by CVD (relative risk, 3.53; 95% CI, 1.27, 9.85; I² = 0%; P heterogeneity = 0.40). Results on the association between MS and all-cause mortality were inconclusive (relative risk, 2.61; 95% CI, 0.70, 9.81; I² = 58%; P heterogeneity = 0.09). Graft loss and death by CVD were associated with the presence of MS after transplantation. Randomized clinical trials should be conducted to define whether interventions on each MS component would result in better outcomes after transplantation.

The Brazilian Cardioprotective Nutritional Program to reduce events and risk factors in secondary prevention for cardiovascular disease: study protocol (The BALANCE Program Trial).

This article reports the rationale for the Brazilian Cardioprotective Nutritional Program (BALANCE Program) Trial. This pragmatic, multicenter, nationwide, randomized, concealed, controlled trial was designed to investigate the effects of the BALANCE Program in reducing cardiovascular events. The BALANCE Program consists of a prescribed diet guided by nutritional content recommendations from Brazilian national guidelines using a unique nutritional education strategy, which includes suggestions of affordable foods. In addition, the Program focuses on intensive follow-up through one-on-one visits, group sessions, and phone calls. In this trial, participants 45 years or older with any evidence of established cardiovascular disease will be randomized to the BALANCE or control groups. Those in the BALANCE group will receive the afore mentioned program interventions, while controls will be given generic advice on how to follow a low-fat, low-energy, low-sodium, and low-cholesterol diet, with a view to achieving Brazilian nutritional guideline recommendations. The primary outcome is a composite of death (any cause), cardiac arrest, acute myocardial infarction, stroke, myocardial revascularization, amputation for peripheral arterial disease, or hospitalization for unstable angina. A total of 2468 patients will be enrolled in 34 sites and followed up for up to 48 months. If the BALANCE Program is found to decrease cardiovascular events and reduce risk factors, this may represent an advance in the care of patients with cardiovascular disease.

Vitamin D insufficiency is associated with lower physical function in patients with heart failure and diabetes.

Vitamin D deficiency is frequent among patients with heart failure (HF) and diabetes, disorders associated with exercise intolerance and muscle weakness. This study aims to search for associations between vitamin D sufficiency and physical function indexes in patients with HF and diabetes. A cross-sectional study of 146 HF patients, 39.7% with diabetes, at a Brazilian tertiary outpatient clinic was performed. Patients underwent clinical evaluation, 6-minute walk test (6 MWT), handgrip strength, physical activity level (IPAQ), and biochemical evaluations including serum 25-hydroxyvitamin D. Classification was done according to vitamin D status (≥ 30 ng/dL, sufficient) and presence/absence of diabetes in vitamin sufficient, no diabetes (DS-C, n = 25), vitamin sufficient, diabetes (DS-DM, n = 18), vitamin deficient, no diabetes (DD-C, n = 63), and vitamin deficient, diabetes (DD-DM, n = 40). Patients age was 55.4 ± 8 yrs; 70.5% had vitamin D deficiency. Clinical characteristics were similar among groups. Total time expended in physical activity was similar among groups (P = 0.26). DS-C covered higher distances in the 6 MWT (392 ± 60 m) versus DD-DM (309 ± 116 m); P = 0.024. Handgrip strength was similar among groups but tended to lower levels in DD-DM (P = 0.074) even after being adjusted to physical activity (P = 0.069). Vitamin D deficiency can influence physical function in HF diabetic patients.

Influence of VKORC1 gene polymorphisms on the effect of oral vitamin K supplementation in over-anticoagulated patients.

Significant inter-individual variability on the effect of vitamin K to reverse overanticoagulation has been identified. Genetic polymorphisms of the vitamin K epoxide reductase complex subunit 1 (VKORC1) gene might explain in part this variability. The objective of this study was to evaluate the influence of VKORC1 -1639G>A and 3730G>A polymorphisms on the effect of oral vitamin K supplementation in overanticoagulated patients. We performed an interventional trial of oral vitamin K supplementation in over-anticoagulated outpatients (international normalized ratio [INR] ≥ 4). Subjects received vitamin K (2.5-5.0 mg) according to baseline INR and were genotyped by real time polymerase chain reaction (PCR). INR values were determined at 3, 6, 24 and 72 h after supplementation. We evaluated 33 outpatients, 61 % were males, with a mean age of 62 ± 12 years old. There was a significant decrease in INR values over time for both polymorphisms after oral vitamin K. At 3 h after supplementation, patients carrying the G allele for the -1639G>A polymorphism had a greater decrease in INR values compared to AA patients (p < 0.05 for difference among groups; p < 0.001 for time variation; p = 0.001 for time × group interaction), with differences of -1.01 for GG versus AA (p = 0.003) and -0.84 for GA versus AA (p = 0.024). Mean INR value at 24 h was 1.9 ± 0.6 and at 72 h was 2.1 ± 0.7, with no differences among genotypes. No significant interaction was identified between the 3730G>A polymorphism and vitamin K supplementation. Our study indicated that the VKORC1 -1639G>A polymorphism plays a role in the response to acute vitamin K supplementation in over-anticoagulated patients, with faster decrease of INR value in patients carrying the G allele.

Association between 276G/T adiponectin gene polymorphism and new-onset diabetes after kidney transplantation.

BACKGROUND: New-onset diabetes after transplantation (NODAT) is a well-recognized complication of kidney transplantation and is associated with poor outcomes. Both adiponectin and chemokine ligand 5 (CCL5) proteins are related to glucose metabolism and genetic variations in their genes can lead to development of NODAT. The aim of this study was to investigate the association of adiponectin and CCL5 genes polymorphisms with NODAT in a population of Caucasian kidney transplant recipients. METHODS: Two hundred seventy Caucasian kidney transplant recipients (83 with NODAT and 187 without NODAT) were included in a nested case-control study. Patients with pretransplantation diabetes mellitus and multiorgan transplantation were excluded. NODAT diagnosis was determined by American Diabetes Association criteria. Subjects were genotyped for 276G/T adiponectin gene polymorphism (rs1501299) and rs2280789 and rs3817655 CCL5 gene polymorphisms by real-time polymerase chain reaction. RESULTS: The TT genotype of 276G/T adiponectin gene polymorphism was significantly more frequent in NODAT than non-NODAT patients compared with GG/GT genotypes (recessive model; P=0.031). TT genotype was identified as an independent risk factor for NODAT in Caucasian kidney transplant recipients after adjusting for age at transplantation, pretransplantation body mass index, and use of tacrolimus (TT vs. GG/GT, hazard ratio=1.88, 95% confidence interval=1.03-3.45, P=0.041). There were no differences in genotype distribution and allele frequency of rs2280789 and rs3817655 CCL5 gene polymorphisms between NODAT and non-NODAT groups. CONCLUSIONS: The 276G/T adiponectin gene polymorphism is associated with NODAT in Caucasian kidney transplant recipients.
