RESUMO
BACKGROUND: The high-density lipoprotein cholesterol to apolipoprotein A-I index (HDL-C/ApoA-I) may be practical and useful in clinical practice as a marker of atherosclerosis. This study aimed to investigate the association between the HDL-C/ApoA-I index with cardiometabolic risk factors and subclinical atherosclerosis. METHODS: In this cross-sectional sub-analysis of the GEA study, 1,363 individuals, women (51.3%) and men (48.7%) between 20 and 75 years old, without coronary heart disease or diabetes mellitus were included. We defined an adverse cardiometabolic profile as excess adipose tissue metrics, non-alcoholic liver fat measured by non-contrasted tomography, metabolic syndrome, dyslipidemias, and insulin resistance. The population was stratified by quartiles of the HDL-C/Apo-AI index, and its dose-relationship associations were analysed using Tobit regression, binomial, and multinomial logistic regression analysis. RESULTS: Body mass index, visceral and pericardial fat, metabolic syndrome, fatty liver, high blood pressure, and CAC were inversely associated with the HDL-C/ApoA-I index. The CAC > 0 prevalence was higher in quartile 1 (29.2%) than in the last quartile (22%) of HDL-C/ApoA-I index (p = 0.035). The probability of having CAC > 0 was higher when the HDL-C/ApoA-I index was less than 0.28 (p < 0.001). This association was independent of classical coronary risk factors, visceral and pericardial fat measurements. CONCLUSION: The HDL-C/ApoA-I index is inversely associated with an adverse cardiometabolic profile and CAC score, making it a potentially useful and practical biomarker of coronary atherosclerosis. Overall, these findings suggest that the HDL-C/ApoA-I index could be useful for evaluating the probability of having higher cardiometabolic risk factors and subclinical atherosclerosis in adults without CAD.

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 (Ï3 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.

INTRODUCTION: Risk scores are essential in primary prevention to detect high-risk patients. The most common scores exclude hypertriglyceridemia and abdominal obesity in their risk assessment. We examined the triglyceride/HDL-cholesterol (TG/HDL-c) ratio as a cardiovascular (CV) risk marker in a middle-class urban Mexican population sample. AIM: Our aim was to test the concept of a scoring system reflecting Mexican population characteristics. METHODS: A total of 2602 healthy adults from the Lindavista primary prevention program were considered, evaluating gender, age, blood pressure, smoking, body mass index, waist circumference, lipid profile, and fasting glucose. According to the abnormality, a score from -3 to +3 was assigned. RESULTS: The summation of eleven variables yielded the Lindavista score (LS), which was calibrated versus the TG/HDL ratio and ACC ASCVD Risk Estimator Plus score to determine its correlation with risk categories. The TG/HDL-c ratio had a linear correlation with LS and high-risk ACC ASCVD categories. CONCLUSIONS: Compared with LS and TG/HDL-c, the ACC ASCVD system underestimates the high-risk category. The high prevalence of obesity and lipid triad in the Mexican population requires a scale that considers those traits. The TG/HDL-c ratio is a practical, easy, and economical instrument to categorize risk in Mexicans.
RESUMO
Relatively little is known about how the diet of chronically undernourished children may impact cardiometabolic biomarkers. The objective of this exploratory study was to characterise relationships between dietary patterns and the cardiometabolic profile of 153 3-5-year-old Peruvian children with a high prevalence of chronic undernutrition. We collected monthly dietary recalls from children when they were 9-24 months old. At 3-5 years, additional dietary recalls were collected, and blood pressure, height, weight, subscapular skinfolds and fasting plasma glucose, insulin and lipid profiles were assessed. Nutrient intakes were expressed as average density per 100 kcals (i) from 9 to 24 months and (ii) at follow-up. The treelet transform and sparse reduced rank regress'ion (RRR) were used to summarize nutrient intake data. Linear regression models were then used to compare these factors to cardiometabolic outcomes and anthropometry. Linear regression models adjusting for subscapular skinfold-for-age Z-scores (SSFZ) were then used to test whether observed relationships were mediated by body composition. 26 % of children were stunted at 3-5 years old. Both treelet transform and sparse RRR-derived child dietary factors are related to protein intake and associated with total cholesterol and SSFZ. Associations between dietary factors and insulin were attenuated after adjusting for SSFZ, suggesting that body composition mediated these relationships. Dietary factors in early childhood, influenced by protein intake, are associated with cholesterol profiles, fasting glucose and body fat in a chronically undernourished population.

Introduction. In recent years, cholesterol has received interest in the study of infection due to evidence of a relationship between low plasma cholesterol levels and tuberculosis (TB).Hypothesis/Gap Statement. Plasma lipid profiles of serum amyloid A (SAA), apolipoprotein A-I and high-density lipoprotein cholesterol (HDL-C) are biomarkers associated with symptomatic TB patients.Objective. We aimed to evaluate plasma lipid profiles of apolipoprotein A-I, SAA and the size of HDL as biomarkers to diagnose symptomatic TB patients.Methodology. Patients with TB symptoms attending the Instituto Brasileiro para a Investigação da Tuberculose/Fundação José Silveira (IBIT/FJS) between September 2015 and August 2016 for diagnosis of TB were studied. From 129 patients, 97 were classified as pulmonary TB and 32 as negative-bacilloscopy (non-TB group). Medical history, fasting serum and plasma were obtained. Total cholesterol (TC), HDL-C, apolipoprotein A-I and SAA were measured by enzymatic or immunochemical reaction assays. HDL size was measured by laser light-scattering.Results. In TB patients, TC (147.0±37 vs. 168±44 mg dL-1), HDL-C (37±14 vs. 55±18 mg dL-1) and apolipoprotein A-I (102±41 vs. 156±47 mg dL-1) concentrations were lower (P<0.0001), while HDL particle size (10.16±1.02 vs. 9.62±0.67 nm) and SAA levels (280±36 vs. 19±8 mg L-1) were higher (P<0.0001). Using receiver-operating characteristic curve analysis for predicting TB, the cutoff values were <83.85 mg L-1 for SAA (sensitivity=96.88â%, specificity=78.43â%, P<0.0001), >44.50 mg dL-1 for HDL-C (sensitivity=75â%, specificity=72.16â%, P<0.001) and >118.5 mg dL-1 for apolipoprotein A-I (sensitivity=83.83â%, specificity=72.22â%, P<0.001).Conclusion. SAA, HDL-C and apolipoprotein A-I are associated with TB infection and could be used as laboratory biomarkers, especially in patients who are negative for alcohol-acid-resistant bacilli.

BACKGROUND: It has already been established that the consumption of alcoholic beverages increases high-density lipoprotein cholesterol (HDL-C) levels in dose-response. METHODS AND RESULTS: A cross-sectional analysis was carried out with 6132 participants of both sexes aged between 35 and 74 years, who were active and retired workers from six Brazilian states. Heavy drinkers were categorized by sex: men > 210 g/week and women > 140 g/week; moderate drinkers: men ≤ 209 g/week and women ≤ 139 g/week. The HDL-C level was dichotomized into normal (40 mg/dL-82.9 mg/dL) and extremely high (≥83 mg/dL). We used binary logistic regression to assess associations between baseline alcohol intake and HDL-C, which were adjusted for sex, age, income, physical activity, kilocalories and body mass index (BMI), and we found an positive association between extremely high HDL-C and the excessive consumption of alcoholic beverages. These participants were mostly women with a high income, lower waist circumference, kilocalorie consumption and also a higher consumption in all categories of alcoholic beverages. CONCLUSION: Excessive alcohol consumption was associated with a higher probability of extremely high HDL-C.

INTRODUCTION: Obesity has been shown to be associated with low levels of soluble receptor for advanced glycation end products (sRAGE). OBJECTIVE: To evaluate the levels of sRAGE and its association with the lipid index in children with obesity. METHODS: Cross-sectional study of children with obesity aged between six and 11 years. Anthropometric measurements, glucose, lipid profile, insulin and sRAGE were evaluated; body mass index, total cholesterol/high-density cholesterol (TC/HDL-C), triglycerides/glucose (TG/glucose), and triglycerides/HDL-C (TG-HDL-C) ratios and HOMA-IR were also calculated. RESULTS: Eighty children were studied, among which 50% were males and 50% females. Females had higher values for waist circumference, HOMA-IR, and TG/HDL-C and TG/glucose ratios. No significant differences were found for sRAGE. When the variables were compared according to TG/HDL-C ratio tertiles, higher TC/HDL, TG/glucose, and sRAGE values were found at upper tertile. A significant correlation was observed between sRAGE and HOMA-IR (p < 0.03) in males, and between sRAGE and TG/HDL-C (p < 0.01) and TG/glucose ratios (p < 0.008) in females. CONCLUSIONS: The female gender showed more cardiovascular risk factors and higher sRAGE at TG/HDL-C upper tertile. Further studies are required to test the possible predictive effect of higher risk for developing metabolic and cardiovascular complications.
INTRODUCCIÓN: Se ha mostrado que la obesidad está asociada a niveles bajos de la forma soluble del receptor para productos finales de glicación avanzada (sRAGE). OBJETIVO: Evaluar los niveles de sRAGE y su asociación con el índice lipídico en niños con obesidad. MÉTODOS: Estudio transversal de niños de seis a 11 años de edad con obesidad. Se evaluaron medidas antropométricas, glucosa, perfil lipídico, insulina y sRAGE; también se calculó índice de masa corporal, colesterol total/C-HDL, triglicéridos/glucosa, triglicéridos/C-HDL y HOMA-IR. RESULTADOS: Se estudiaron 80 niños, 50 % hombres y 50 % mujeres. Las mujeres presentaron mayor perímetro de cintura, HOMA-IR, triglicéridos/C-HDL y triglicéridos/glucosa. No se encontraron diferencias significativas en sRAGE. Al comparar las variables conforme a los terciles de la relación triglicéridos/C-HDL, en el tercil superior se encontraron mayores valores de colesterol total/HDL, triglicéridos/glucosa y sRAGE. Se observó correlación significativa entre sRAGE y HOMA-IR (p < 0.03) en los hombres y entre sRAGE, triglicéridos/C-HDL (p < 0.01) y triglicéridos/glucosa (p < 0.008) en las mujeres. CONCLUSIONES: El sexo femenino mostró más factores de riesgo cardiovascular y mayor sRAGE en el tercil superior de triglicéridos/C-HDL. Se requieren más estudios para probar el posible efecto predictor de mayor riesgo para desarrollar complicaciones metabólicas y cardiovasculares.

RESUMO
Resumo Fundamento Além da doença arterial coronariana, a lipoproteína de não alta densidade (não-HDL-C) fornece informações preditivas de curto e longo prazo para muitas doenças inflamatórias crônicas, como acidente vascular cerebral, hemodiálise, pós-transplante renal, hepatoesteatose não alcoólica e vírus da imunodeficiência humana. Objetivos Este estudo examinou o valor preditivo do não-HDL-C medido antes do SARS-CoV-2 para mortalidade na infecção por COVID-19. Métodos Este estudo incluiu retrospectivamente 1.435 pacientes diagnosticados com COVID-19 e tratados na enfermaria de doenças torácicas em um único centro entre janeiro de 2020 e junho de 2022. Todos os pacientes incluídos no estudo apresentavam características clínicas e radiológicas e sinais de pneumonia por COVID-19. O diagnóstico de COVID-19 de todos os pacientes foi confirmado por uma reação em cadeia da polimerase estudada a partir de um swab orofaríngeo. A significância estatística foi estabelecida em p < 0,05. Resultados Os pacientes do estudo, incluindo 1.435 indivíduos, foram divididos em 712 pacientes no grupo de não sobreviventes e 723 no grupo de sobreviventes. Embora não tenha havido diferença entre os grupos em relação ao sexo, houve uma diferença de idade estatisticamente significativa. O grupo que não sobreviveu era mais velho. Idade, lactato desidrogenase (LDH), proteína C reativa (PCR), triglicerídeos, D-dímero e não-HDL-C foram fatores de risco independentes para mortalidade em análises de regressão. Na análise de correlação, idade, PCR e LDH foram positivamente correlacionados com não-HDL-C. Na análise ROC, a sensibilidade para não-HDL-C foi de 61,6% e a especificidade foi de 89,2%. Conclusão Acreditamos que o nível de não HDL-C estudado antes da infecção por COVID-19 pode ser usado como um biomarcador prognóstico para a doença.
Abstract Background In addition to coronary artery disease, non-high-density lipoprotein(non-HDL-C) provides short and long-term predictive information for many chronic inflammatory diseases such as stroke, hemodialysis, post-renal transplant, non-alcoholic hepatosteatosis, and human immunodeficiency virus. Objectives This study examined the predictive value of non-HDL-C measured before SARS-CoV-2 for mortality in COVID-19 infection. Methods This study retrospectively included 1435 patients diagnosed with COVID-19 and treated in the thoracic diseases ward in a single center between January 2020 and June 2022. All patients included in the study had clinical and radiological features and signs of COVID-19 pneumonia. The COVID-19 diagnosis of all patients was confirmed by a polymerase chain reaction studied from an oropharyngeal swab. Statistical significance was set at p < 0.05. Results The study patients, including 1435 subjects, were divided into 712 patients in the non-surviving group and 723 in the surviving group. While there was no difference between the groups regarding gender, there was a statistically significant age difference. The non-surviving group was older. Age, lactate dehydrogenase(LDH), C reactive protein(CRP), triglycerides, D-dimer, and non-HDL-C were independent risk factors for mortality in regression analyses. In correlation analysis, age, CRP, and LDH were positively correlated with non-HDL-C. In the ROC analysis, sensitivity for non-HDL-C was 61.6%, and specificity was 89.2%. Conclusion We believe that the non-HDL-C level studied before COVID-19 infection can be used as a prognostic biomarker for the disease.
