RESUMO

OBJECTIVE: To explore the potential associations between high-density lipoprotein (HDL) levels and inflammasome components in the context of systemic lupus erythematosus (SLE). METHODS: A cross-sectional study was conducted. A group of 50 patients with SLE and 50 healthy controls matched by sex and similar age ranges were enrolled. Serum HDL cholesterol (HDL-C) and C reactive protein (CRP) levels were quantified. Serum cytokine levels, including IL-1ß and IL-6, were determined by ELISA. The gene expression of inflammasome-related genes in peripheral blood mononuclear cells was measured by quantitative real-time PCR. RESULTS: HDL-C levels were lower in the patients with SLE (p<0.05), and on segregation according to disease activity, those with active SLE had the lowest HDL-C levels. Patients with SLE presented higher concentrations of the serum inflammatory cytokines IL-1ß and IL-6 (p<0.0001) but similar levels of CRP to those in controls. A similar scenario was observed for the gene expression of inflammasome components, where all the evaluated markers were significantly upregulated in the SLE population. These results revealed significant negative correlations between HDL levels and disease activity, serum IL-6 and IL-1ß levels and the mRNA expression of NLRP3, IL-1ß and IL-18. In addition, significant positive correlations were found between disease activity and serum IL-1ß and between disease activity and the mRNA expression of IL-18, and interestingly, significant positive correlations were also observed between active SLE and serum IL-1ß and the mRNA expression of NLRP3. CONCLUSION: Our results suggest that HDL is essential for SLE beyond atherosclerosis and is related to inflammation regulation, possibly mediated by inflammasome immunomodulation.

RESUMO

OBJECTIVE: The clinical utility of high-density lipoprotein cholesterol (HDL-C) in risk classification is limited, especially in midlife women. Novel metrics of HDL may better reflect this risk. We clustered a comprehensive profile of HDL metrics into favorable and unfavorable clusters and assessed how these two clusters are related to future subclinical atherosclerosis (carotid intima media thickness [cIMT], interadventitial diameter [IAD], and carotid plaque presence) in midlife women. METHODS: Four hundred sixty-one women (baseline age: 50.4 [2.7] years; 272 White, 137 Black, 52 Chinese) from the Study of Women's Health Across the Nation HDL ancillary study who had baseline measures of HDL cholesterol efflux capacity (HDL-CEC), lipid contents (HDL-phospholipids [HDL-PL] and HDL triglycerides [HDL-Tg]), and HDL particle (HDL-P) distribution and size, followed by carotid ultrasound (average 12.9 [SD: 2.6] years later), were included. Using latent cluster analysis, women were clustered into a favorable (high HDL-CEC, HDL-PL, large and medium HDL-P, less HDL-Tg and small HDL-P, larger size) or an unfavorable HDL cluster (low HDL-CEC, HDL-PL, large and medium HDL-P, more HDL-Tg, and small HDL-P, smaller size) and then linked to future subclinical atherosclerosis using linear or logistic regression. RESULTS: The favorable HDL cluster was associated with lower cIMT, IAD, and odds of carotid plaque presence. These associations were attenuated by body mass index, except in Chinese women where the association with cIMT persisted (0.72 [0.63, 0.83]). CONCLUSIONS: The association between favorable HDL clusters and a better postmenopausal subclinical atherosclerosis profile is largely explained by body mass index; however, racial/ethnic differences may exist.

RESUMO

OBJECTIVE: The aim of this article is to investigate the effect of intermittent fasting, associated or not with coconut oil intake, on the gut-liver axis of obese rats. METHODS: A total of 50 rats were divided into five groups: control, obese, obese with intermittent fasting, obese with intermittent fasting plus coconut oil, and obese with caloric restriction. The rats were induced to obesity with a high-sugar diet for 17 wk. The respective interventions were carried out in the last 4 wk. RESULTS: The groups with intermittent fasting protocols had reduced total cholesterol (on average 54.31%), low-density lipoprotein (on average 53.39%), and triacylglycerols (on average 23.94%) versus the obese group; and the obese with intermittent fasting plus coconut oil group had the highest high-density lipoprotein compared with all groups. The obese with intermittent fasting plus coconut oil and obese with caloric restriction groups had lower metabolic load compared with the other groups. The obese group had high citric and succinic acid concentrations, which affected the hepatic tricarboxylic acid cycle, while all the interventions had reduced concentrations of these acids. No histologic changes were observed in the intestine or liver of the groups. CONCLUSION: Intermittent fasting, especially when associated with coconut oil, had effects comparable with caloric restriction in modulating the parameters of the gut-liver axis.

RESUMO

Introdução: A prevalência de doenças cardiovasculares tem crescido em todo o mundo. Além da hipercolesterolemia, fatores como o envelhecimento, menopausa, diferenças no metabolismo do colesterol entre homens e mulheres e entre etnias, provavelmente contribuem para as prevalências dessas doenças. Objetivo: Avaliar a influência da menopausa, da idade (adolescentes, adultos e idosos), do sexo e da etnia sobre as subfrações lipoproteicas aterogênicas. Métodos: Trata-se de um estudo transversal, de base populacional e amostra probabilística de residentes da cidade de São Paulo. Foram utilizados dados de participantes "ISA-CAPITAL 2015" que tiveram coleta de dados bioquímicos. Foram realizadas análises de partículas de LDL e HDL respectivamente, em 827 amostras. O tamanho das partículas de LDL e HDL foi determinado pelo sistema Lipoprint® System (Quantimetrix Corporation. Todos os testes estatísticos foram realizados com o auxílio do programa SPSS 16. Foi considerado significativo p<0,05. Resultados: As análises com adolescentes mostraram que as meninas apesar de possuírem maior IMC, CC e concentração de TG, apresentaram melhor perfil de subfrações de LDL (LDL grande% 17,8; LDL pequena% 1,7) do que os meninos (LDL grande% 13,5; LDL pequena% 3,4) p<0,001 e p=0,002, respectivamente. Entre os indivíduos adultos, foi identificado um perfil mais aterogênico entre homens, com maior percentual de LDL pequena, quando comparados às mulheres (4,9% vs 2,7%; p<0,001, respectivamente). Com relação à população idosa, os resultados demonstraram que apesar do avanço da idade, as idosas quando comparadas aos idosos possuíam maior concentração LDL grande (32,5mg/dL vs 28,5mg/dL; p=0,007 respectivamente). As mulheres idosas tiveram uma piora das subfrações lipoproteicas se comparadas com as mulheres adultas (razão de LDL mg/dL=12,3 mulheres adultas vs 10,7 mulheres idosas; p=0,002) se aproximando ao perfil mais aterogênico encontrado entre os homens (razão de LDLmg/dL=9,9 homens adultos vs 9,0 homens idosos; p=0,027). Entretanto, quando pareadas por homens de mesma idade, as mulheres idosas, ainda assim, demonstraram um perfil menos aterogênico do que os homens idosos (razão de LDL mg/dL=10,7 mulheres idosas vs 9,0 homens idosos; p=0,001). Ao analisar a presença de menopausa, foi identificado que as mulheres no período pós menopausa tiveram piora do perfil lipídico clássico com aumento do IMC (p=0,025), CC (p<0,001), glicose (p<0,001), PAS (p<0,001), PAD (p=0,005) e TG (p<0,001), assim como tiveram piora do perfil lipoproteico com diminuição de LDL grande% quando comparadas com as mulheres no período pré menopausa (17,6% vs 14,6%; p=0,001). Quanto à etnia, foi identificado que os indivíduos brancos apresentaram valores maiores para IMC (p=0,005), CC (p=0,001), glicose (p=0,015) e TG (p=0,010). Após ajustes para etnia, idade e IMC, houve associação positiva com HDL grande (=0,122; R2=0,013; p=0,001), demonstrando maior aterogenicidade entre os indivíduos brancos. Conclusão: Em todas as faixas etárias o sexo feminino apresentou perfil menos aterogênico quando comparado ao masculino. A presença de menopausa e da etnia branca demonstrou um perfil lipídico clássico e lipoproteico mais aterogênico.


Introduction: The prevalence of cardiovascular diseases has increased throughout the world. In addition to hypercholesterolemia, factors such as aging, menopause, differences in cholesterol metabolism between men and women and between ethnicities probably contribute to the prevalence of these diseases. Objective: To evaluate the influence of menopause, age (adolescents, adults and elderly), sex and ethnicity on atherogenic lipoprotein subfractions. Methods: This is a cross-sectional, population-based study with a probabilistic sample of residents of the city of São Paulo. Data from "ISA-CAPITAL 2015" participants who had biochemical data collected were used. LDL and HDL particle analyzes were carried out respectively in 827 samples. The size of LDL and HDL particles was determined using the Lipoprint® System (Quantimetrix Corporation. All statistical tests were performed with the aid of the SPSS 16 program. Was considered significant p<0.05. Results: Analyzes with adolescents showed that girls, despite having higher BMI, WC and TG concentration, presented a better profile of LDL subfractions (LDL large% 17.8; LDL small% 1.7) than boys (LDL large% 13.5; LDL small% 3.4) p<0.001 and p=0.002, respectively. Among adult individuals, a more atherogenic profile was identified among men, with a higher percentage of LDL small, when compared to women (4.9% vs 2.7%; p<0.001, respectively). Regarding the elderly population, the results demonstrated that despite advancing age, elderly women, when compared to elderly men, had a higher large LDL concentration (32.5mg/dL vs 28.5mg/dL; p=0.007 respectively). Elderly women had a worsening of lipoprotein subfractions compared to adult women (LDL ratio mg/dL=12.3 adult women vs 10.7 elderly women; p=0.002) approaching the more atherogenic profile found among men (LDLmg/dL ratio=9.9 adult men vs 9.0 elderly men; p=0.027). However, when paired with men of the same age, elderly women still demonstrated a less atherogenic profile than elderly men (LDL ratio mg/dL=10.7 elderly women vs 9.0 elderly men; p=0.001). When analyzing the presence of menopause, it was identified that women in the postmenopausal period had a worsening of the classic lipid profile with an increase in BMI (p=0.025), WC (p<0.001), glucose (p<0.001), SBP (p< 0.001), DBP (p=0.005) and TG (p<0.001), as well as a worsening of the lipoprotein profile with a reduction in LDL large when compared to women in the premenopausal period (17.6% vs 14.6%; p=0.001). Regarding ethnicity, it was identified that white individuals presented higher values for BMI (p=0.005), WC (p=0.001), glucose (p=0.015) and TG (p=0.010). After adjustments for ethnicity, age and BMI, there was a positive association with HDL large (=0.122; R2=0.013; p=0.001), demonstrating greater atherogenicity among white individuals. Conclusion: In all age groups, females presented a less atherogenic profile when compared to males. The presence of menopause and white ethnicity demonstrated a more atherogenic classic lipid and lipoprotein profile.

RESUMO

The effects of regular physical activity on two important anti-atherosclerosis functions of high-density lipoprotein (HDL), namely its capacity to receive both forms of cholesterol and its anti-oxidant function, were investigated in this study comparing older adults with young individuals. One-hundred and eight healthy adult individuals were enrolled and separated into the following groups: active older (60-80 yrs, n = 24); inactive older (60-79 yrs, n = 21); active young (20-34 yrs, n = 39); and inactive young (20-35 yrs, n = 24). All performed cardiopulmonary tests. Blood samples were collected in order to assess the following measures: lipid profile, HDL anti-oxidant capacity, paraoxonase-1 activity, HDL subfractions, and lipid transfer to HDL. Comparing active older and active young groups with inactive older and inactive young groups, respectively, the active groups presented higher HDL-C levels (p < 0.01 for both comparisons), unesterified cholesterol transfer (p < 0.01, p < 0.05), and intermediate and larger HDL subfractions (p < 0.001, p < 0.01) than the respective inactive groups. In addition, the active young group showed higher esterified cholesterol transfer than the inactive young group (p < 0.05). As expected, the two active groups had higher VO2peak than the inactive groups; VO2peak was higher in the two younger than in the two older groups (p < 0.05). No differences in unesterified and esterified cholesterol transfers and HDL subfractions were found between active young and active older groups. HDL anti-oxidant capacity and paraoxonase-1 activity were equal in all four study groups. Our data highlight and strengthen the benefits of regular practice of physical activity on an important HDL function, the capacity of HDL to receive cholesterol, despite the age-dependent decrease in VO2peak.

RESUMO

(1) Background: Previous studies have enriched high-density lipoproteins (HDL) using cholesteryl esters in rabbits with a three-quarter reduction in functional renal mass, suggesting that the kidneys participate in the cholesterol homeostasis of these lipoproteins. However, the possible role of the kidneys in lipoprotein metabolism is still controversial. To understand the role of the kidneys in regulating the HDL lipid content, we determined the turnover of HDL-cholesteryl esters in rabbits with a three-quarter renal mass reduction. (2) Methods: HDL subclass characterization was conducted, and the kinetics of plasma HDL-cholesteryl esters, labeled with tritium, were studied in rabbits with a 75% reduction in functional renal mass (Ntx). (3) Results: The reduced renal mass triggered the enrichment of cholesterol, specifically cholesteryl esters, in HDL subclasses. The exchange of cholesteryl esters between HDL and apo B-containing lipoproteins (VLDL/LDL) was not significantly modified in Ntx rabbits. Moreover, the cholesteryl esters of HDL and VLDL/LDL fluxes from the plasmatic compartment tended to decrease, but they only reached statistical significance when both fluxes were added to the Nxt group. Accordingly, the fractional catabolic rate (FCR) of the HDL-cholesteryl esters was lower in Ntx rabbits, concomitantly with its accumulation in HDL subclasses, probably because of the reduced mass of renal cells requiring this lipid from lipoproteins.

RESUMO

The objective of this study was to evaluate the influence of different heat-stress-reducing systems, i.e., sprinkler + artificial shade, shower + artificial shade, and artificial shade, on serum mineral, hormonal, hematological, and metabolite profiles, on milk production, and milk composition in lactating cows and pubertal heifers of Holstein and Jersey breeds. For this purpose, 12 animals were used: 3 Holstein cows with an average (mean ± SD) body weight of 600 ± 30 kg, 53 ± 11 months of age, and milk yield of 27 ± 3.5 kg/day; 3 Jersey cows with an average body weight of 370 ± 11 kg, 40 ± 6 months of age, and milk production of 11 ± 1.5 kg/day; 3 Holstein heifers (325 ± 25 kg and 16 ± 0.6 months of age); and 3 Jersey heifers (250 ± 25 kg and 13 ± 0.6 months of age). Animals were used in a replicated 3 × 3 Latin square design with a 3 × 2 × 2 factorial arrangement of treatments that included three treatments (sprinkler + artificial shade, shower + artificial shade, and artificial shade), two breeds (Holstein, Jersey), and two physiological stages (lactating cows, heifers). The experimental treatments influenced (P < 0.05) the concentrations of triiodothyronine, with the shower and shade systems showing greater and similar concentrations (99.5 and 96.3 µg/dL, respectively) when compared with sprinkler treatment (89.2 µg/dL). There was an effect (P < 0.05) of breed on the concentrations of Na + , K + , hemoglobin, hematocrit and mean corpuscular volume levels with the Holsteins having lower levels of Na + , K + , hemoglobin, hematocrit and mean corpuscular volume (101.1, 4.0 ng/mL, 11.2 g/dL, 24.7%, and 42.3 µm3, respectively) than the Jerseys (106.5 and 4.3 ng/mL, 12.4 g/dL, 27.7%, and 46.3 µm3, respectively. Total cholesterol and high-density lipoproteins were influenced by physiological stage (P < 0.05). Concentrations of cholesterol and high-density lipoproteins were higher for cows (94.1, and 56.9 mg/dL, respectively) than for heifers (56.9 and 42,9 mf/dL, respectively). Milk production and fat content were affected (P < 0.05) by breed (P < 0.05), with Holstein cows producing more milk (23.9 kg/day) than Jersey cows (12.0 kg/day), but Jersey cows had higher fat concentration (4.6%) than Holstein cows (3.0%). Therefore, the three different thermal-stress-reducing-systems tested were able to maintain the serum biomarkers within normal physiological ranges. However, the most appropriate thermal-stress-reducing-systems would be a sprinkler systema because it uses less water compared with the shower system.

RESUMO

Previous studies have highlighted the role of lifestyle on HDL-C concentrations in adults. To our knowledge, the health and nutritional status of emerging adults have been understudied. The present study aimed to explore the most important lifestyle factors, including micronutrient intake adequacy and the percentage of energy from food processing, according to HDL-C concentrations in emerging adults. In this context, a cross-sectional analysis was conducted on 261 Mexican emerging adults who were apparently healthy. Lifestyle factors were collected through a structured survey and the prevalence of micronutrient intake inadequacy was estimated using the estimated average requirement cut-point method. The percentage of energy from ultra-processed foods was assessed using the NOVA system. HDL-C was determined using the enzymatic colorimetric method. Statistical analyses were conducted in SPSS. The results revealed that lifestyle factors do not differ according to HDL-C status. The participants showed a poor nutritional diet that was energy-dense and micronutrient-inadequate. Nearly half of their energy came from processed and ultra-processed foods. Most participants did not meet the recommendations for key nutrients (ϖ3 fatty acids and phytosterols) that promote a healthy lipid status. In conclusion, regardless of their HDL-C levels, emerging adults exhibited lifestyle-related risk factors. The persistence of these findings over time could contribute to the development of metabolic disorders in the future. It is crucial to increase understanding and to develop effective nutritional interventions during this critical phase of life.

RESUMO

Background: Several indexes have been developed to define the risk attributable to lipid metabolism with a single value. The total cholesterol/high-density lipoprotein (TC/HDL-C) and low-density lipoprotein/high-density lipoprotein (LDL-C/HDL-C) ratios are the most used. The higher the value of these ratios, the greater the probability of cardiovascular events. Objective: To identify whether the TC/HDL-C and LDL-C/HDL-C ratios are early prognostic markers of mortality and major cardiovascular events in patients with ST-elevation acute coronary syndrome. Material and methods: 265 patients with ST-segment elevation acute coronary ischemic syndrome were included, divided into 4 groups according to the values of the atherogenic indices. Mortality and major cardiovascular events at 30-day follow-up were analyzed. Comparison of the groups was performed using the chi-squared test or ANOVA, depending on the case (p < 0.05). Results: The cut-off point for the TC/HDL-C index was 6.9 and for the LDL-C/HDL-C it was 2.7. The comparative analysis of groups showed that cardiovascular death and arrhythmia were higher in group 3 (p = 0.006 and p = 0.003, respectively). Conclusions: TC/HDL-C and LDL-C/HDL-C indexes can be used as prognostic markers of cardiovascular mortality in the first 30 days of follow-up.


Introducción: se han elaborado diferentes índices para definir el riesgo atribuible al metabolismo lipídico con un solo valor. Los coeficientes colesterol total/lipoproteínas de alta densidad (CT/C-HDL) y lipoproteínas de baja densidad/lipoproteínas de alta densidad (C-LDL/C-HDL) son los más utilizados. A mayor valor de estos cocientes, la probabilidad de eventos cardiovasculares es mayor. Objetivo: identificar si los índices CT/C-HDL y C-LDL/C-HDL son marcadores pronósticos tempranos de mortalidad y evento cardiovascular mayor en pacientes con síndrome isquémico coronario agudo con elevación del ST. Material y métodos: se incluyeron 265 pacientes con síndrome isquémico coronario agudo con elevación del segmento ST, divididos en 4 grupos según los valores de los índices aterogénicos. Se analizó la mortalidad y el evento cardiovascular mayor en los 30 días de seguimiento. Se identificó el punto de corte de cada índice mediante un análisis de curva ROC. La comparación de los grupos se hizo con chi cuadrada o ANOVA, según fuera el caso (p < 0.05). Resultados: el punto de corte para el índice CT/C-HDL fue de 6.9 y para el C-LDL/C-HDL de 2.7. El análisis comparativo de los grupos demostró que la muerte cardiovascular y arritmia fue mayor en el grupo 3 (p = 0.006 y p = 0.003, respectivamente). Conclusiones: los índices CT/C-HDL y C-LDL/C-HDL pueden ser utilizados como marcadores pronósticos de mortalidad cardiovascular en los primeros 30 días de seguimiento.

RESUMO

Adolescence is a complex period of human development in which young people are susceptible to unhealthy behaviors, such as physical inactivity and an unbalanced diet. This study aimed to analyze the effects of 12 weeks of multi-disciplinary family and individual intervention on cardiometabolic risk parameters in overweight and obese adolescents and compare sub-groups, considering possible differences between sexes (males vs. females vs. intervention approach). Forty-three adolescents (13.73 ± 2.46 years old) of both sexes were divided into two groups: family group (FG) (n = 21; 14.24 ± 2.61 years old) and individual group (IG) (n = 22; 13.23 ± 2.27 years old). The following parameters were evaluated: anthropometry (body weight, height, waist circumference (WC), hip circumference (HC), abdominal circumference (AC), calculation of body mass index (BMI), and waist-hip ratio (WHR)), body composition (fat mass (FM), lean mass (LM), fat-free mass (FFM), skeletal muscle mass (SMM), body fat percentage (BF), and visceral fat), biochemical measures (fasting glucose, triglycerides (TG), total cholesterol (TC), low-density lipoproteins (LDL-c), and high-density lipoproteins (HDL-c)), and the measurement of systolic and diastolic blood pressure (SBP and DBP) before and after the interventions. The multi-disciplinary interventions occurred for 12 weeks (three days a week lasting 1 h and 30 min, in which 30 min were dedicated to theoretical interventions (nutrition: nutritional education and psychology: psychoeducation) and 1 h to physical exercises. A time effect was observed for LM, FFM, SMM, FM, and HDL-c, with higher values after intervention and a significant decrease for FM, BF, visceral fat, fasting glucose, TG, TC, LDL-c, and DBP (p < 0.05). However, no group, sub-group, or interaction effects were observed when comparing FG, IG, or sexes (p > 0.05). The responses of the present study show that both multi-disciplinary approaches (family and individual) promoted improvement in the body composition indicators, biochemical markers, and DBP of overweight and obese adolescents independently of the intervention group. Given this finding, health professionals, families, and adolescents could choose the type of intervention based on their preferences.
