The let-7b-5p, miR-326, and miR-125a-3p are associated with left ventricular systolic dysfunction in post-myocardial infarction.

Background: Acute ST-elevation myocardial infarction (STEMI) can lead to adverse cardiac remodeling, resulting in left ventricular systolic dysfunction (LVSd) and heart failure. Epigenetic regulators, such as microRNAs, may be involved in the physiopathology of LVSd. Objective: This study explored microRNAs in peripheral blood mononuclear cells (PBMC) of post-myocardial infarction patients with LVSd. Methods: Post-STEMI patients were grouped as having (LVSd, n = 9) or not LVSd (non-LVSd, n = 16). The expression of 61 microRNAs was analyzed in PBMC by RT-qPCR and the differentially expressed microRNAs were identified. Principal Component Analysis stratified the microRNAs based on the development of dysfunction. Predictive variables of LVSd were investigated through logistic regression analysis. A system biology approach was used to explore the regulatory molecular network of the disease and an enrichment analysis was performed. Results: The let-7b-5p (AUC: 0.807; 95% CI: 0.63-0.98; p = 0.013), miR-125a-3p (AUC: 0.800; 95% CI: 0.61-0.99; p = 0.036) and miR-326 (AUC: 0.783; 95% CI: 0.54-1.00; p = 0.028) were upregulated in LVSd (p < 0.05) and discriminated LVSd from non-LVSd. Multivariate logistic regression analysis showed let-7b-5p (OR: 16.00; 95% CI: 1.54-166.05; p = 0.020) and miR-326 (OR: 28.00; 95% CI: 2.42-323.70; p = 0.008) as predictors of LVSd. The enrichment analysis revealed association of the targets of these three microRNAs with immunological response, cell-cell adhesion, and cardiac changes. Conclusion: LVSd alters the expression of let-7b-5p, miR-326, and miR-125a-3p in PBMC from post-STEMI, indicating their potential involvement in the cardiac dysfunction physiopathology and highlighting these miRNAs as possible LVSd biomarkers.

Are Phosphatidylcholine and Lysophosphatidylcholine Body Levels Potentially Reliable Biomarkers in Obesity? A Review of Human Studies.

Phosphatidylcholines (PCs) are the major components of biological membranes in animals and are a class of phospholipids that incorporate choline as a headgroup. Lysophosphatidylcholines (LPCs) are a class of lipid biomolecules derived from the cleavage of PCs, and are the main components of oxidized low-density lipoproteins (oxLDLs) that are involved in the pathogenesis of atherosclerosis. Since obesity is associated with a state of chronic low-grade inflammation, one can anticipate that the lipidomic profile changes in this context and both PCs and LPCs are gaining attention as hypothetically reliable biomarkers of obesity. Thus, a literature search is performed on PubMed, Latin American and Caribbean Health Science Literature (LILACS), and Excerpta Medica DataBASE (Embase) to obtain the findings of population studies to clarify this hypothesis. The search strategy resulted in a total of 2403 reports and 21 studies were included according to the eligibility criteria. Controversial data on the associations of PCs and LPCs with body mass index (BMI) and body fat parameters have been identified. There is an inverse relationship between BMI and most species of PCs, and a majority of studies exhibited negative associations between BMI and LPCs. Other findings regarding the differences between PCs and LPCs in obesity are presented, and the associated uncertainties are discussed in detail.

Plasma Concentration of Essential and Toxic Trace Elements After Brazil Nut Intake: Results from a Randomized Controlled Trial.

Brazil nut (BN) is a good source of essential nutrients, but little is known about the content of other components, such as toxic elements. Moreover, the high consumption of BN could probably contribute to increased levels of toxic and essential elements in the blood. Thus, this study aimed to evaluate the concentration of essential and toxic trace elements in BN and their concentration in plasma of obese women after regular intake of BN. A randomized controlled clinical trial was carried out with 55 subjects that were randomly assigned to either the Brazil nut group (BN) (n = 29) or the control group (CO) (n = 26) and followed up for 2 months. The BN group consumed one unit of Brazil nut per day, and the CO group did not receive any intervention. The concentration of essential elements (zinc, copper, manganese, and cobalt) and toxic (barium, lead, and cadmium) in BN samples and plasma of obese women (before and after the intervention) were determined by inductively coupled plasma mass spectrometry. Barium followed by copper, and manganese were the trace elements present in higher amounts in Brazil nuts. After the BN intervention period was observed an increase in plasma cadmium (p = 0.002) and a reduction of plasma manganese (p < 0.001) levels. In conclusion, our findings suggest that the regular consumption of BN from the Brazilian Amazon rainforest contributes to the intake of essential trace elements and can be considered safe regarding the content of heavy metals.

Previous vitamin D status and total cholesterol are associated with SARS-CoV-2 infection.

BACKGROUND: The relationship of vitamin D status and other biochemical parameters with the risk of SARS-CoV-2 infection remains inconclusive, especially in regions with high solar incidence. Therefore, we aimed to associate the 25-hydroxyvitamin D (25(OH)D) concentrations and lipid profile prior to the SARS-CoV-2 tests in a population from a sunny region in Brazil (5 degrees S, 35 degrees W). METHODS: This retrospective cohort study enrolled 1634 patients tested for SARS-CoV-2 of a private medical laboratory with 25(OH)D concentration and lipid profile measured ≥ 7 days before the date of the first SARS-CoV-2 RT-PCR test and were categorized according to 25(OH)D sufficiency (≥30 ng/mL) or insufficiency (<30 ng/mL). Multiple logistic regression analyses were performed to assess risk factors associated with positive tests for SARS-CoV-2. RESULTS: Average serum 25(OH)D was 33.6 ng/mL. Vitamin D deficiency (<20 ng/mL) was only found in 2.6% of the participants. Multivariate analysis demonstrated that patients > 49 y with insufficient 25(OH)D (<30 ng/mL) presented increased odds to test positive for SARS-CoV-2 (OR: 2.02, 95 %CI: 1.15 to 3.55, P = 0.015). The same is observed among those with total cholesterol > 190 mg/dL (OR: 1.90, 95 %CI: 1.10 to 3.28, P = 0.020). CONCLUSIONS: Previous insufficient 25(OH)D (<30 ng/mL) concentration and high total cholesterol were associated with SARS-CoV-2 infection among adults > 48 y in the study population. Further studies should be conducted to confirm whether measurement of 25(OH)D and lipid profile could be useful to identify patients who are more susceptible to COVID-19.

Zinc nutritional status influences ZnT1 and ZIP4 gene expression in children with a high risk of zinc deficiency.

INTRODUCTION: Subclinical deficiency of zinc is associated with impairment of immune system function, growth, and cognitive development in children. Although plasma zinc is the best available biomarker of the risk of zinc deficiency in populations, its sensitivity for early detection of deficiency is limited. Therefore, we aimed to investigate zinc deficiency among preschool children and its relationship with whole blood gene expression of zinc transporters ZIP4 and ZnT1. MATERIAL AND METHODS: This cross-sectional study included 139 children aged 32-76 months enrolled in philanthropic day-care centers. We performed an anthropometric evaluation, weighed food record and dietary record for dietary assessment, blood sample collection for zinc, and whole blood gene expression analyses of ZnT1 (SLC30A1) and ZIP4 (SLC39A4). RESULTS: Zinc deficiency was observed in 26.6 % of the children despite adequate zinc intake and a phytate:zinc molar ratio < 18. Usual zinc intake did not affect whole blood gene expression of zinc transporters, but zinc status influenced ZnT1 and ZIP4 whole blood mRNA. Children with zinc deficiency exhibited 37.1 % higher ZnT1 expression and 45.3 % lower ZIP4 expression than children with adequate zinc (p < 0.05). CONCLUSION: Children with plasma zinc deficiency exhibited higher expression of ZnT1 and lower expression of ZIP4 in whole blood mRNA, reinforcing the existence of strong regulation of mineral homeostasis according to the nutritional status, indicating that this analysis may be useful in the evaluation of dietary interventions.

Brazil nut intake increases circulating miR-454-3p and miR-584-5p in obese women.

The Brazil nut is an excellent source of selenium (Se), an essential micronutrient for human health. In this study, we hypothesized that Brazil nut intake modulates circulating microRNAs (miRNAs) in obese women and aimed to evaluate the effects of this nut intake on circulating miRNAs in women with obesity or metabolic syndrome (MetS). A randomized controlled clinical trial was conducted on 54 subjects recruited from the Clinical Hospital in São Paulo, Brazil. Patients were randomly assigned to 2 groups: a Brazil nut group (BN group, n = 29) and a control group (CO group, n = 25); both were monitored for 2 months. BN group members were instructed to consume 1 Brazil nut (approximately 1261 µg/Se) per day; CO group members were instructed not to consume any. Biochemical parameters related to Se status and 25 circulating miRNAs in plasma were evaluated in all patients both at baseline and after 2 months. Expression levels of 2 miRNAs (miR-454-3p and miR-584-5p) were significantly increased after Brazil nut intake. To investigate the effect of MetS on circulating miRNAs at baseline, we performed comparisons between women with MetS (n = 23) and women without MetS (others, n = 31). Circulating miR-375 levels were significantly lower (P = .012) in women with MetS. In conclusion, our findings suggested that a daily intake of 1 Brazil nut increased circulating miR-454-3p and miR-584-5p expression levels in obese women, and our network analysis indicated a link between Se intake, vitamin D metabolism, and calcium homeostasis.

Consumption of Brazil nuts with high selenium levels increased inflammation biomarkers in obese women: A randomized controlled trial.

OBJECTIVE: Increased inflammatory response is an important factor in the pathophysiology of obesity. The mineral selenium (Se), of which one of the main food sources is the Brazil nut, has important antioxidant and anti-inflammatory functions through the action of selenoproteins. Thus, the evaluation of the influence of this micronutrient in this context is of great relevance. The aim of this study was to evaluate the effects of Brazil nut intake with high Se concentrations on inflammatory biomarkers and its relation to Se status in obese women. METHODS: A randomized controlled clinical trial was carried out with 55 women recruited at Clinical Hospital in São Paulo, Brazil. Patients were randomly assigned to either the Brazil nut group (BN) or the control group (CO) and followed up for 2 mo. The BN group consumed 1 unit/d of Brazil nuts (∼ 1261 µg/Se); the CO group did not receive any intervention. At baseline and after 2 mo, analysis of biochemical parameters related to Se status, oxidative stress, and inflammatory biomarkers were performed. RESULTS: At baseline, both groups did not present Se deficiency. In the BN group, a significant increase (P < 0.05) in all Se biomarkers and in gene expression of several proinflammatory parameters (interleukin-6, tumor necrosis factor-α, and Toll-like receptors 2 and 4) were observed after the intervention period. No changes were observed for the CO group. CONCLUSION: Although there were no changes in plasma inflammatory biomarkers levels, a significant increase in gene expression may be an indication of a proinflammatory stimulus in obesity, induced by the consumption of Brazil nuts with high Se levels.

Erythrocyte SOD1 activity, but not SOD1 polymorphisms, is associated with ICU mortality in patients with septic shock.

The objective of our study was to evaluate the influence of the superoxide dismutase 1 (SOD1) polymorphisms on erythrocyte SOD1 activity and the mortality of patients with septic shock. We prospectively evaluated 175 patients aged over 18 years with septic shock upon ICU admission. However, 38 patients were excluded. Thus, 137 patients were enrolled in the study. Blood samples were taken within the first 24 h of the patient's admission to determine erythrocyte SOD1 activity and nine SOD1 gene polymorphisms. The mean patient age was 63 ±â€¯16 years, 58% were men, and ICU mortality rate was 66%. The patients who died were older and more severely ill, with higher Acute Physiology and Chronic Health Evaluation (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores, as well as higher lactate, urea, and protein carbonyl levels. In the logistic regression model, erythrocyte SOD1 activity was associated with ICU mortality. This relationship was also maintained in the highest tertile of SOD1 activity (odds ratio [OR]: 0.02; 95% confidence interval [CI]: 0.00-0.78; p = 0.037). Only SNP rs2070424 of the SOD1 gene influenced erythrocyte SOD1 activity. For patients with the AA allele, the activity of SOD1 was lower in relation to G-carriers (A/G+G/G genotype) (p = 0.019). None of the nine SOD1 SNPs were associated with ICU mortality. In conclusion, the SNP rs2070424 of the SOD1 gene interferes with erythrocyte SOD1 activity, and higher activity of SOD1 was associated with decreased mortality in patients with septic shock.

Expressão de microRNA circulantes em mulheres com excesso de peso suplementadas com castanha-do-brasil / Expression of circulating microRNAs in overweight and obese women supplemented with Brazil nut

O aumento excessivo de peso corporal acompanhado do acúmulo de gordura visceral eleva o risco de morbidade por hipertensão, diabetes mellitus tipo 2 e doença cardiovascular (DCV). O estresse oxidativo e a inflamação desempenham papel etiológico nestas comorbidades. Neste contexto, os microRNA (miRNA) atuam na regulação pós-transcricional no intuito de manter a homeostase celular sob condições de estresse fisiológico. A expressão de miRNA pode ser modulada por nutrientes e compostos bioativos provenientes da alimentação, atuando sobre processos inflamatórios, reduzindo o risco e/ou atenuando a progressão das DCV. A castanha-do-brasil é a maior fonte alimentar de selênio, sendo considerada um alimento com potencial função antioxidante podendo ser utilizado em pacientes com elevado risco cardiovascular. Dessa forma, o objetivo do presente estudo foi avaliar a expressão de microRNA circulantes em mulheres com excesso de peso antes e após o consumo da castanha-do-brasil. Para isso, foram selecionadas 72 mulheres com excesso de peso que frequentam o serviço de endocrinologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP). As participantes foram distribuídas aleatoriamente em dois grupos: grupo intervenção (grupo Brazil Nut - BN), que consumiu uma unidade de castanha-do-brasil durante 60 dias, e grupo controle (CO), que não recebeu intervenção durante o mesmo período. Ao início e ao final da intervenção foram realizadas avaliações antropométricas e coleta de sangue. Foram incluídas no estudo 54 participantes: 29 do grupo BN e 25 do grupo CO. Nenhuma das variáveis antropométricas e bioquímicas apresentou variação significativa entre os grupos durante o período de intervenção. Conforme esperado, apenas o grupo BN apresentou um aumento significativo do selênio plasmático e eritrocitário durante o período de intervenção (> 200%; P<0,001). Foram avaliados 25 miRNA plasmáticos antes e após a intervenção. Dois miRNA (miR-454-3p e miR-584-5p) apresentaram aumento significativo (fold change maior que 2,2; P<0,05) após a ingestão de castanha-do-brasil. A análise dos seus possíveis alvos pelo software Ingenuity Pathway Analysis (IPA®, Qiagen) apontou que ambos estão relacionados com a via de ativação do VDR/RXR, podendo apresentar efeitos sobre a homeostase do cálcio, regulação do crescimento e função imune. O miR-454-3p apresentou, ainda, correlação positiva com a variação do selênio plasmático (r=0,432; P=0,005) e diversos miRNA apesentaram correlação significativa com parâmetros relacionados à síndrome metabólica e à resistência à insulina. Dessa forma, podemos concluir que o consumo da castanha-do-brasil por 60 dias é capaz de modular a expressão de miRNA circulantes em mulheres com excesso de peso, particularmente do miR-454-3p e do miR-584-5p, podendo estes serem utilizados como possíveis biomarcadores de ingestão e auxiliar, ainda, no entendimento dos mecanismos pelos quais o selênio exerce seu efeito na saúde dessa população

Excessive body weight gain accompanied by visceral fat accumulation raises the morbidity risk due to hypertension, type 2 diabetes mellitus and cardiovascular disease (CVD). Oxidative stress and inflammation play etiological role in these comorbidities. In this context, microRNAs (miRNAs) act in post-transcriptional regulation in order to maintain cellular homeostasis under physiological stress. MicroRNAs expression can be modulated by nutrients and bioactive compounds from the diet, acting on inflammatory processes, reducing the risk and/or attenuating the progression of CVD. Brazil nut is the major food source of selenium, being considered a food with potential antioxidant function to be used in patients with high cardiovascular risk. Thus, the present study aimed to evaluate the expression of circulating miRNAs in overweight and obese women before and after Brazil nuts intake. Thus, we selected 72 overweight and obese women recruited at Division of Endocrinology and Metabolism from the Clinical Hospital (School of Medicine, University of São Paulo, São Paulo, Brazil). Participants were randomly assigned to two groups: intervention group (Brazil Nut - BN group), which consumed one Brazil nut for 60 days, and control group (CO), which received no intervention during the same period. At the baseline and at the end of the intervention were performed anthropometric assessments and blood collection. The study included 54 participants: 29 from the BN group and 25 from the CO group. None of the anthropometric and biochemical variables presented significant variation between the groups during the intervention period. As expected, only the BN group showed a significant increase in plasma and erythrocyte selenium during the intervention period (> 200%; P<0.001). We evaluated 25 circulating miRNAs before and after the intervention. Two miRNAs (miR-454-3p and miR-584-5p) presented a significant increase (fold change greater than 2.2; P <0.05) after Brazil nuts intake. The analysis of potential targets by the Ingenuity Pathway Analysis software (IPA®, Qiagen) indicated that both are related to the VDR/RXR activation pathway, and may have effects on calcium homeostasis, growth regulation and immune function. Furthermore, miR-454-3p presented a positive correlation with plasma selenium (r = 0.432, P = 0.005) and several miRNAs showed a significant correlation with parameters related to metabolic syndrome and insulin resistance. Thus, we conclude that Brazil nut inatke for 60 days is capable of modulating circulating miRNAs in overweight and obese women, particularly miR-454-3p and miR-584-5p, and these may be used as possible biomarkers of intake and help to understand the mechanisms by which selenium exerts its effect on health of this population

Intervenção nutricional educativa como ferramenta eficaz para mudança de hábitos alimentares e peso corporal entre praticantes de atividade física / Educational nutritional intervention as an effective tool for changing eating habits and body weight among those who practice physical activities

O presente estudo avaliou a eficácia de dois métodos de intervenção nutricional educativa entre mulheres praticantes de atividade física regular visando à adoção de práticas alimentares saudáveis. A população foi constituída de 52 mulheres de 19 a 59 anos, frequentadoras do Programa Academia da Cidade (Aracaju, SE). O estudo teve delineamento de comparação de dois grupos de intervenção e foi do tipo pré-teste/pós-teste. As ações educativas foram baseadas em dois protocolos, uma com ação menos intensiva (Grupo P1) e outra mais intensiva (Grupo P2), num período de dois meses. As variáveis analisadas foram as de conhecimento nutricional, medidas antropométricas e mudanças nos hábitos alimentares. As modificações identificadas foram melhora nos hábitos alimentares e redução do peso e Índice de Massa Corpórea para o Grupo P2. As modificações citadas referiram-se, principalmente, ao aumento do consumo de frutas, verduras e legumes, redução de gordura das preparações, redução do volume do alimento ingerido por refeição e aumento do fracionamento da dieta. Em relação aos conhecimentos em nutrição apenas 2 das 12 perguntas apresentaram aumento significativo da nota. A intervenção nutricional mais intensiva mostrou-se eficaz para mudanças de hábitos alimentares com repercussão na perda de peso corporal.

CONCLUSION: The population presented poor eating habits, especially young and overweight women. Therefore, educational nutrition strategies are very important and highly recommended for the promotion of healthier lifestyles.

Perfil de saúde, estado nutricional e nível de conhecimento em nutrição de usuárias do Programa Academia da Cidade - Aracaju, SE / Profile of health, nutritional status and knowledge of level in nutrition Academia da Cidade Program of users - Aracaju, SE

Condições sócio-econômicas desfavoráveis, hábitos alimentares inadequados e sedentarismo representam fatores de risco para o desenvolvimento da obesidade e das doenças crônicas não transmissíveis na população. Assim, o objetivo desse estudo foi avaliar o perfil de saúde, o estado nutricional e o nível de conhecimento nutricional de mulheres praticantes de atividade física do Programa Academia da Cidade, Aracaju, SE. Foram coletados dados sócio-econômicos, condições de saúde, nutrição e conhecimento nutricional. O questionário é composto por 12 questões divididas por assunto em 3 grupos de perguntas. As medidas antropométricas aferidas foram massa corporal, estatura, perímetro da cintura e quadril. Foram avaliadas 191 usuárias do programa com média de idade de 51,9 (±9,02) anos, estando 75,4% com excesso de peso de acordo com o índice de massa corporal e 57,7 % com alto risco de desenvolvimento para doenças crônicas não transmissíveis, segundo a relação cintura-quadril. Foi observado que mulheres com maior gordura central (RCQ?0,85cm) apresentaram maior prevalência de hipertensão e diabetes (p<0,05). Cerca de 64,8 % da população apresentou conhecimento nutricional moderado com nota média de 7,0. Indivíduos com maior renda apresentaram notas significativamente maiores no conhecimento nutricional total e no grupo 2 de perguntas (alimentos fonte de fibras e gorduras) . A população estudada apresentou alta prevalência de sobrepeso e obesidade, colocando em risco seu quadro de saúde. O moderado conhecimento em nutrição e a obtenção de notas inferiores entre aqueles com menor renda mostra a necessidade do desenvolvimento de ações de educação nutricional nesta população para promoção de hábitos alimentares saudáveis.

Inadequate socioeconomic conditions, dietary habits and physical inactivity are risk factors for developing obesity and chronic diseases in population. Therefore, the aim of this study was to evaluate the health profile, nutritional status and nutritional knowledge level of women who practice physical activity from the Academia da Cidade Program, Aracaju, SE. Were collected socio-economics data, health and nutrition profiles, besides the application of a questionnaire of nutritional knowledge evaluation. The questionnaire consists of 12 questions divided by subject into three groups of questions. The anthropometric data measured were body weight, height, waist and hip circumference. Were evaluated 191 users of the program with a mean age of 51,9 years, being 45.1% overweight according to body mass index and 57.7% with high risk, according to waist-to-hip ratio risk for development of chronic diseases. Women with greater central fat (WHR ? 0.85 cm) showed a higher prevalence of hypertension and diabetes (p <0.05). About 64.8% of the population presented moderate nutritional knowledge with an average score of 7,0. Individuals with higher incomes had significantly higher scores of total nutrition knowledge and in group 2 (food source of fiber and fat) of questions. The studied population had high prevalence of overweight and abdominal obesity. The moderate knowledge in nutrition and getting lower scores among those with lower income shows the necessity of developing nutritional education activities in this population to promote healthy eating habits.
