Abstract 4140142: Neighborhood Perceptions Associate with Lipid Biomarkers in African-American Women with Cardiovascular-Kidney-Metabolic Syndrome: Data from the Step It Up Digital Health-Enabled, Community-Engaged Physical Activity Intervention

Background: Cardiovascular-kidney metabolic (CKM) syndrome is exacerbated among individuals experiencing chronic exposure to both environmental and psychosocial stressors. Both neighborhood and individual-level stressors increase chronic inflammation resulting in worsened CKM factors, such as hypertension, diabetes, and dys/hyperlipidemia. However, associations between neighborhood perceptions (NP) and lipid profiles remain understudied. Therefore, we examined associations between NP domains and lipid profiles among African-American (AA) women with ≥Stage 1 CKM syndrome (overweight/obesity) residing in resource-limited neighborhoods within the Washington, DC area. Methods: Participants were enrolled in Step It Up, a technology-enabled, community-engaged physical activity (PA) intervention. Fasting blood samples were drawn at baseline to measure lipoproteins using Nuclear Magnetic Resonance (NMR) spectroscopy. Factor analysis of overall NP identified four perception sub-scores: disorder, social cohesion, violence, and safety (higher score=favorable perception). Associations between NP domains and lipoprotein particles were analyzed using multivariable regression adjusting for BMI, ASCVD 10-year risk score, and lipid-lowering therapy. Results: Participants (n=169) had mean age=57.16 ± 12.00 and BMI 35.99 ± 6.57. Perceptions of safety were positively associated with LDL concentrations (LDLc) and large LDL particles (L-LDLp) (β=4.70 [SD=2.41], p=0.05, β= 43.75 [17.70], p= 0.01), respectively). Perceptions about neighborhood violence were positively associated with L-LDLp (marginally) and very-low-density lipoprotein size (VLDLz) (β= 7.10 [3.96], p=0.08, β= 0.31 [0.14], p= 0.02, respectively). No associations were found between disorder and social cohesion with lipid biomarkers. Conclusions: After adjusting for BMI, ASCVD risk, and lipid-lowering therapy, there were significant associations between neighborhood perceptions of safety and violence with lipid profiles among AA women with CKM syndrome. Greater perceived safety was associated with higher LDLc and L-LDLp while more favorable perception about neighborhood violence was associated with higher L-LDLp. Future work should examine whether improving neighborhood resources and perceptions may improve CKM health among urban AA women.

A comparative study of the Anti-Diabetic effects of avocado seed extracts and biosynthesized silver nanoparticles in Alloxan-Induced diabetic Albino mice

In this research, a comparative study of the anti-diabetic effects of Avocado (Persea americana) seed extracts and biosynthesized silver nanoparticles (Ag NPs) in alloxan-induced diabetic albino mice was conducted. The animals were assigned into twenty-one groups of five animals each; the diabetes was induced by intraperitoneal injection of 150 mg/kg of the prepared alloxan monohydrate. After 15–25 days of using 7.5 mg/ml aqueous extract of P. americana seeds, it was found that blood sugar levels dropped significantly. In addition, over the 20–25 days treatment period, levels of blood sugar were reduced considerably when doses of 5.0 or 10 mg/ml of the aqueous extract were introduced. However, throughout this treatment period, animals injected with 2.5, 5.0, 7.5, or 10.0 mg/ml of P. americana seed aqueous extract showed a significant rise in weight. In addition, over 20–25 days of treatment, animals treated with 7.5 and 10.0 mg/ml P. americana seed alcoholic extract showed a substantial decrease in blood sugar levels. Over the 25 days of treatment, animals treated with 7.5 mg/ml P. americana seed in alcoholic extract also showed a noticeable rise in weight. On the other hand, the prepared Ag NPs were synthesized and characterized using color changes, UV–visible spectroscopy, SEM, and AFM analysis. A substantial reduction in blood sugar levels was noted with 2.5 mg/ml of biosynthesized Ag NPs, while mice weights significantly increased. The highest substantial reduction in glycaemia occurred by combining 7.5 mg/ml aqueous extract and 2.5 mg/ml biosynthesized Ag NPs, resulting in a high increase in animal weight across all combination concentrations. Regarding the interaction between combination concentrations and treatment periods, animals’ weight increased significantly in all combined concentrations during the 20–25 days compared to the control. Furthermore, an increase in LDL and VLDL concentrations was observed in the negative control group compared to the positive control and other treated groups.

The Effect of Time-Restricted Eating on Cardiometabolic Risk Factors: A Systematic Review and Meta-Analysis.

Background/Objectives: Endogenous metabolic pathways periodically adjust with fluctuations in day and night, a biological process known as circadian rhythm. Time-restricted eating (TRE) aligns the time of food intake with the circadian rhythm. This study aims to investigate the effects of TRE on body weight, body composition and cardiometabolic risk factors. Methods: We reviewed articles from PubMed and Cochrane libraries for clinical trials that compare TRE with regular diet without calorie restriction. We conducted a meta-analysis of 26 studies. Results: Participants who followed TRE demonstrated reduction in body weight [mean-MD: -1.622 kg, (95% confidence interval (CI -2.302 to -0.941)], body mass index (BMI) [MD: -0.919 kg/m2 (95% CI: -1.189 to -0.650)], waist circumference [MD: -2.015 cm (95% CI: -3.212 to -0.819] and whole-body fat mass (WBFM) [MD: -0.662 kg (95% CI: -0.795 to -0.530)]. Improvements in cardiometabolic risk factors such as a decrease in insulin concentrations [MD: -0.458 mIU/L, (95% CI: -0.843 to -0.073)], total cholesterol [MD: -2.889 mg/dL (95% CI: -5.447 to -0.330) and LDL concentrations [MD: -2.717 mg/dL (95% CI: -4.412 to -1.021)] were observed. Conclusions: TRE is beneficial for weight loss and improvements in cardiometabolic risk factors. Further large-scale clinical trials are needed to confirm these findings.

Glutathione s-transferase pi is a marker of loop diuretic resistance in patients with congestive heart failure exacerbation

Abstract Background Loop diuretic resistance (LDR) in patients with heart failure (HF) exacerbation is associated with worse clinical outcomes, greater symptom burden and mortality. Diagnosis and treatment of LDR remains a significant clinical dilemma. Purpose To assess the ability of different urine biomarkers to predict LDR in patients with HF exacerbation. Methods Consecutive patients with congestive HF exacerbation were prospectively included in the study. HF was diagnosed according to ESC 2021 HF Guidelines definition. Congestion was defined as a presence of one or more of the following signs: edema, ascites, pleural effusion. LDR was defined as persistent congestion on the 4th day of hospital stay despite high i.v. loop diuretic dose. Urine biomarkers released from different parts of the nephron (Kidney Injury Molecule-1 - KIM-1, N-acetyl-β-D-glucosaminidase - NAG, uromodulin, glutathione S-transferase Pi - pi-GST, aquaporin-2), transthoracic echo, clinical and biochemical parameters were evaluated on the 1st and 4th day of hospital stay. Results are presented as mean ±standard deviation or median (interquartile range). Results 40 patients were included in the study with median age 84 (72,8; 86) years, median left ventricle ejection fraction (EF) 35.3 (26,5; 49) %, median NT-proBNP 8967.5 (3024; 15241) pg/ml. LDR was found in 14 (35%) patients. Univariate analysis identified the following risk factors for LDR: urine pi-GST concentration on admission and on the 4th day, right ventricle to pulmonary circulation coupling index (TAPSE/PASP ratio), presence of mitral regurgitation, serum creatine concentration, serum urea concentration, serum LDL concentration. Logistic regression analysis identified pi-GST concentration as a significant independent risk factor for LDR in this population: odds ratio (OR) 5.75 [95% confidence interval (CI) 1.271–25.990]. Conclusions Urine pi-GST on admission and after 4 days of treatment might be a marker for a development of LDR in patients with congestive HF exacerbation.

Population Pharmacokinetic and Pharmacodynamic of Atorvastatin in Chinese Lung Transplant Recipients.

Atorvastatin is a widely prescribed cholesterol-lowering drug that inhibits 3-hydroxy-3-methylglutaryl coenzyme A reductase to reduce lipid levels. This study aimed to establish a population pharmacokinetic and pharmacodynamic model for atorvastatin in Chinese lung transplant recipients (LTRs), particularly those using voriconazole (VOR) and with different genotypes. It evaluated precise dosing regimens and analyzed the correlation between atorvastatin exposure and clinical outcomes. A nonlinear mixed-effects model was used for the population pharmacokinetic/pharmacodynamic (PK/PD) analysis. A one-compartment population PK model was developed, incorporating VOR, SLCO2A1 rs76906503, and SLC22A8 rs2187383 to assess apparent clearance and volume of distribution. LDL-C was modeled as a biomarker to evaluate atorvastatin efficacy. A Monte Carlo simulation was conducted to assess various dosing schemes and the effects of different covariates on achieving the target LDL concentration. The correlation between atorvastatin exposure and clinical outcomes was also evaluated. Results indicated that the average probability of target attainment for optimal dosing regimens across various covariate results exceeded 45.8%. Dosages of 10, 20, and 40 mg were deemed suitable for LTRs. A lower dose was recommended for LTRs taking VOR or with mutant-type genotypes to avoid overexposure and adverse reactions. The population PK/PD model offers valuable guidance for evaluating atorvastatin dosing regimens in clinical settings, particularly for LTRs using VOR and those with different genotypes.

A Physiological Study of the Effect of Bee Pollen on Albino Rats Induced Hypothyroidism

The current study aimed to evaluate the therapeutic role of bee pollen (BP) in reducing the harmful effects resulting from hypothyroidism compared to the drug thyroxine on some physiological indicators and improving their levels, which included weight gain (gm), hormone level (T3, T4, TSH), level TPO, cholesterol levels, HDL, LDL, VLDL, and liver enzymes ALT, AST, Hypothyroidism was induced in (24) male rats using the drug carbimazole (CBZ) Which lasted for (15) days at 30 mg/kg of body weight. A random sample was chosen to confirm the occurrence of hypothyroidism, as the results of examining blood samples that were drawn from the animals showed a high concentration of the TSH hormone and Low concentrations of thyroid hormones in the serum compared to the negative control., and this indicates the occurrence of hypothyroidism. Then the animals in which hypothyroidism was induced were separated into 3 experimental collections in addition to the control group and a fifth group. Each group consists of (8) animals. The dosing period lasted thirty days orally. The negative control group, G1, was provided with a diet and water freely. G2 was continued to be dosed with the drug (CBZ) at a concentration of 30 mg/kg of body weight. G3 was continued to be dosed with the drug (CBZ) at a concentration of 30 mg/kg and solution (BP). At a concentration of 200 mg/kg body weight, G4 was dosed with levothyroxine at a concentration of 20 mg/kg body weight, while G5 was dosed with BP solution only at a concentration of 200 mg/kg body weight. At the end of the experiment, the animals were sacrificed and blood samples were obtained. The results were less than 0.05 in group G2 in body weight, the concentration of thyroid hormones T3 and T4, and the concentration of TPO and HDL, and a significant increase (P<0.05) in the concentration of TSH, Cholesterol, LDL, and VLDL, respectively, with an increase in the concentration of liver enzymes. AST and ALT compared to the control group. As for the G3 and G4 groups, the result appeared an original increase a total body weight and the concentration of the hormones T3, T4, and the TPO enzyme, a noticeable improvement in the lipid profile, and a low level of the ALT enzyme and the and thyroid-stimulating hormone compared to the G2 group. As for the group G5 has witnessed an increase in T4 concentration and a decrease in ALT concentration and body weight, and the concentrations of T3, TSH, and TPO are closer to control. We conclude from the current study that BP has a role in reducing the effects of hypothyroidism, increasing weight gain, and improving the lipid profile and the level of ALT liver enzymes. AST and Thyroid peroxidase (TPO) level.

Concentric remodeling and the metabolic-associated steatotic liver disease in patients with type 1 diabetes: an exploratory study.

Diabetic cardiomyopathy in young patients with type 1 diabetes (T1D) usually presents as asymptomatic diastolic heart dysfunction with left ventricle (LV) remodeling. Its prevalence seems to be underestimated. One of the factors seemingly influencing LV remodeling is a metabolic-associated steatotic liver disease (MASLD), which was extensively investigated in patients with type 2 diabetes but not with T1D. This study aimed to describe the correlation between MASLD risk and relative wall thickness (RWT) in young patients with T1D without heart failure symptoms or treatment. Study participants were recruited at the inpatient diabetology department, in admission order. Patients underwent a set of laboratory tests and echocardiographic examinations. The risk of MASLD was estimated using fatty liver index (FLI). Acquired data was then statistically analyzed. The study group consisted of 55 patients. 25 participants had RWT > 0.42, suggesting LV remodeling. Study participants did not differ in HbA1c, NT-proBNP, HDL, LDL, non-HDL, and uric acid concentrations. However, patients with RWT > 0.42 had higher FLI (40.97 vs. 13.82, p < 0.01) and BMI (27.3 vs. 22.5, p < 0.01) and differed in transaminase concentrations. Moreover, patients with RWT > 0.42 had significantly higher LV mass index (85.6 vs. 68.2g/m2) and altered mitral ring velocities. In univariable logistic regression, FLI correlated with LV remodeling risk (OR 1.028, p = 0.05). The optimal cutoff point for FLI predicting the RWT > 0.42 was 26.38 (OR 10.6, p = 0.04, sensitivity 0.857, specificity 0.657). FLI correlates with RWT in patients with T1D independently of diabetes metabolic control and hypothetically may support recognizing T1D patients with a higher risk of LV remodeling.

Feeding milk thistle (Silybum mariamum) seed powder to fattening lambs: Effects on growth performance, digestibility and rumen metabolism

This experiment was conducted to evaluate the effect of milk thistle (Silybum marianum) seed powder supplementation in the diet on weight gain, feed conversion efficiency, and physiological parameters in fattening lambs. In this experiment, thirty crossbred Shawl × Romanov male lambs were divided into three groups based on a completely randomized design. The experimental treatments included a control group receiving a diet without milk thistle seed powder (MSP), a group receiving a diet containing 1 % MSP, and a group receiving a diet containing 2 % MSP. Animals fed the diet containing 2 % MSP exhibited higher nutrient intake, average daily gain, and final body weight compared to the other treatment groups (P < 0.05). Lambs receiving the 2 % MSP diet had the most favorable feed conversion ratio (P < 0.05). The apparent digestibility of dry matter, organic matter, and crude protein was highest in lambs fed the diet containing MSP compared to the control group (P < 0.05). Ruminal NH3-N concentration and populations of total protozoa and Entodinium genus were lowest in lambs fed the MSP-containing diets (P < 0.05). The molar concentrations of acetate and valerate in the rumen fluid of lambs receiving the diet containing 2 % MSP were lower compared to the control group, while propionate concentration was higher (P < 0.05). Feeding the diet containing 2 % MSP reduced serum cholesterol, triglycerides, LDL, and liver enzyme activities compared to the control group (P < 0.05). Based on these results, supplementing lamb diets with 2 % MSP increased growth performance measures, nutrient digestibility coefficients, and reduced blood cholesterol and LDL concentrations.

Exploring correlations: Human seminal plasma and blood serum biochemistry in relation to semen quality.

Male infertility is a pressing global issue, prompting the need for biomarkers correlating with seminal parameters for diagnosis. Our study investigated 10 biochemical and energetic parameters in the seminal plasma and blood sera of fertile (25 subjects) and infertile (88 subjects) Polish men, correlations between their levels in seminal plasma and semen quality, and correlations between blood sera and seminal plasma levels of examined parameters. Infertile men displayed elevated seminal plasma glucose and fructose but reduced HDL levels compared to fertile men. We observed also weak negative correlations between seminal plasma triglycerides and sperm concentration in both groups. Moreover, infertile men exhibited positive correlations between seminal plasma HDL/LDL concentrations and sperm concentration. Fertile men showed moderate negative correlations between glucose/triglycerides concentrations and sperm count and between seminal plasma triglycerides levels and sperm vitality. Semen volume correlated with triglycerides (negative) and fructose (positive) concentrations in infertile men. Sperm motility correlated negatively with total cholesterol, LDL, and triglycerides concentrations in fertile men, and weakly with AMP-activated protein kinase in infertile men. Weak negative correlations between seminal plasma fructose/AMP-activated protein kinase concentrations and sperm progressive motility were observed in infertile men, whereas in fertile men seminal plasma AMP-activated protein kinase levels were positively correlated with progressive motility. Correlation analysis between blood serum and seminal plasma parameters revealed intriguing connections, notably regarding LDL, AMP-activated protein kinase, and carnitine, suggesting systemic influences on seminal plasma composition. These findings emphasize the complex interplay between metabolic factors and sperm parameters, offering promising directions for future research in male infertility diagnostics and therapeutics.

Cholesin receptor signalling is active in cardiovascular system-associated adipose tissue and correlates with SGLT2i treatment in patients with diabetes

BackgroundRecently deorphanized G protein-coupled receptor 146 (GPR146) was shown to respond to signal from a newly identified hormone—cholesin—and to play a role in hepatic lipid metabolism. However, the importance of its biological activity in human organism remains elusive, mainly due to the lack of studies on human tissues up to this point. This study aimed to identify the cholesin receptor-associated genes and clinical factors linked with their expression in cardiovascular system and associated adipose tissues.MethodsRight cardiac auricle, aortic wall, saphenous vein, and adipose tissue (periaortic-PAT, epicardial-EAT, thymic-TAT) samples were collected during coronary artery bypass grafting. Clinical records of the study participants were assessed for the presence of diabetes, medications taken and serum cholesterol levels. GPR146 mRNA expression in all gathered tissues was assessed with qPCR, and RNA seqencing was performed in selected tissues of 20 individuals to identify pathways associated with GPR146 expression.ResultsWe included 46 participants [37 male, 23 with type 2 diabetes, median age 68.50 (Q1–Q3: 63.00–72.00) years, BMI 28.39 (26.06–31.49) kg/m2]. GPR146 expression in adipose tissues significantly correlated with BMI, c-peptide, total cholesterol, and LDL concentrations. Selected metabolic pathways were significantly and positively enriched in GPR146-dependent manner. GPR146-coexpressed genes contained key regulators of lipid metabolism involved in such pathways as fatty acid metabolism, tricarboxilic acid cycle and peroxisomal metabolism. Those genes correlated positively with serum concentrations of LDL, HDL, and total cholesterol. SGLT2i treatment was associated with inversion of GPR146-related signature in EAT, suggesting potential impact on cholesin-GPR146 network.ConclusionsGPR146 expression is associated with serum lipids and metabolically-relevant transcriptomic changes in EAT similar to SGLT2i-associated ones.Graphical abstract

Maternal Lipid Profile Changes in Gestational Diabetes Mellitus

Introduction: Pregnancy is commonly recognized as a state of physiological and temporary insulin resistance. This condition is driven by high concentrations of steroid hormones such as progesterone, estrogens, prolactin, cortisol and placenta-derived human placental lactogen. All of these are diabetogenic and combined cause for decreased sensitivity of insulin receptors within target tissues. Women with prior GDM are at greater risk for developing hypertension, hyperlipidaemia and electrocardiogram abnormalities. Materials and Methods: seventy five patients with Gestational diabetes mellitus and 75 healthy Normal pregnant women were enrolled for the study after the institutional ethical committee’s clearance was obtained. The fasting blood samples of the study subjects were evaluated for the glucose, lipid profile, Glycated Haemoglobin (HbA1c), Malondialdehyde (MDA) and calculated BMI. Results: Lipid peroxidation is enhanced in GDM group as MDA values have elevated significantly (p &lt; 0.0001) compared to normal pregnancy. Total cholesterol (p&lt; 0.001) and LDL (p = 0.001) are found to be significantly higher in GDM, but there are no significant differences in triglycerides and HDL between normal and diabetic pregnant women. Obesity is observed in GDM group as their BMI (p &lt; 0.001) is significantly higher than that of the control group. Conclusions: It was found that GDM is associated with hyperlipidaemia as evidenced by the significantly elevated total cholesterol and LDL concentrations. Obesity and lipid peroxidation are significantly high in GDM. Keywords: Gestational diabetes mellitus, HbA1c, lipid profile, lipid peroxidation, BMI.

Determining the Effectiveness of Lactobacillus Casei in Camel Milk on Lipid and Sugar Parameters in Type 1 Diabetic Rats

Introduction: Nutritional interventions are one of the most effective methods of diabetes prevention and control. Along with usual treatments, camel milk has had positive effects on the blood sugar of diabetic patients. The present study was conducted with the aim of investigating the effect of lactobacillus casei present in camel milk on the sugar and lipid profile of type 1 diabetic rats. Methods: This was of an intervention study and carried out by an experimental trial method. 32 mice were randomly divided into four groups of eight. After making diabetic, the rats were gavage with 2cc of the product prepared for each group every other day. Evaluations (weight, serum concentrations of glucose, FBS, urea, creatinine, uric acid, LDL, HDL, TG, cholesterol, as well as liver enzymes AST, ALT, and ALP) were performed after 30 days of receiving gavage. In order to analyze the data, SPSS16 software was used. Results: The mean weight and serum concentration of LDL in the treatment group with standard and native Lactobacillus casei probiotics was significantly lower than the diabetic control group (P&lt;0.05) and the mean HDL in the treatment group with standard and native Lactobacillus casei probiotics was higher than the diabetic control group (P&lt;0.05), but there was no significant difference between the native Lactobacillus casei probiotic group and the standard. Urea, uric acid, FBS, Cr, TG, cholesterol, AST, ALT and ALP was not significantly different between the standard and native Lactobacillus casei probiotic group and the diabetic control one (P&gt;0.05). Conclusion: It seems that lactobacillus casei probiotics from camel milk may be able to improve weight loss and improve lipid profile (increase in HDL, decrease in LDL and LDL/HDL ratio) in type 1 diabetic rats, which requires more extensive studies in this field.

#980 Lipid spectrum in patients with coronary artery disease with contrast-induced nephropathy during X-ray endovascular procedures

Abstract Background and Aims Study of the main indicators of the lipid spectrum in patients with coronary artery disease with contrast-induced nephropathy (CIN), which developed during X-ray endovascular procedures (ERP). Method The study included 303 patients with stable forms of coronary artery disease who underwent X-ray endovascular procedures (REP). The average age of the patients was 53.79 ± 1.27 years. Based on the results, all patients were divided into 2 groups - patients with an uncomplicated postoperative period of REP (CIN− group, 206 patients, 67.99%) and patients who developed contrast-induced nephropathy (CIN+ group, 97 patients, 32.01%). Kidney filtration function was assessed by the clearance of endogenous cystatin C with calculation of the glomerular filtration rate (eGFRcys=90.63 × cystatin C – 1.192). Three fractions of lipoproteins were selected as indicators of the lipid spectrum: cholesterol containing LDL and HDL, as an anti-atherogenic factor, and VLDL, the main triglyceride-containing fraction. Results It was found that in patients in the CIN+ group, the LDL level was significantly higher than that characteristic of the CIN− group (p&amp;lt;0.001) and CG (p&amp;lt;0.001). At the same time, in the CIN− and CG groups, the LDL concentration was comparable, despite the use of statins in the groups of patients with coronary artery disease. The concentration of the second studied atherogenic fraction, VLDL, was also increased in patients with IHD compared with the CG (p&amp;lt;0.001 compared with both groups of patients with IHD) with a maximum increase in patients of the CIN+ group (p&amp;lt;0.01 significance of the difference between the CIN+ and KIN−). The concentration of the antiatherogenic fraction of the lipid spectrum—HDL—was significantly and comparable reduced in both groups of patients with coronary artery disease (p&amp;lt;0.001 when comparing both groups of patients with CG). Conclusion In the course of this study, it was found that one of the risk factors for the development of CIN in patients with coronary artery disease after REP is an increased concentration of atherogenic lipoproteins in the peripheral blood. A decrease in the level of anti-atherogenic HDL in the present study was not associated with the risk of developing CIN, but serves as a marker of impaired glomerular function kidney.

Association of Apolipoprotein E (APOE) Polymorphisms With Serological Lipid and Inflammatory Markers.

Background The study aims to assess the association of apolipoprotein E (APOE) gene polymorphisms with serological lipid and inflammatory markers to determine their potential role in predicting the risk of cardiovascular diseases (CVDs) and Alzheimer's disease (AD). Methodology A total of 915 individuals underwent testing for lipid and inflammatory biomarkers at Vibrant America Clinical Laboratory. Clinical data, blood lipid and inflammatory profiles, and APOE genotyping were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results Compared to the E3/E3 genotype, individuals with E2/E3 genotypes showed higher levels of high-density lipoprotein (HDL), triglycerides, apolipoprotein A (APOA), high-sensitivity C-reactive protein (hs-CRP), and myeloperoxidase (MPO). E2/E4 genotype carriers had higher levels of HDL, triglycerides, Lp(a), and N-terminal pro b-type natriuretic peptide (BNPNT). E3/E4 genotypes were associated with elevated levels of total cholesterol, LDL, Lp(a), hs-CRP, small-density low-density lipoprotein (SDLDL), oxidized LDL (OXLDL), MPO, LDL-CAL, PLAC, and APOB. The E4/E4 group displayed higher concentrations of total cholesterol, LDL, APOB, Lp(a), hs-CRP, SDLDL, OXLDL, MPO, LDLCAL, and PLAC compared to E3/E3 carriers. These findings highlight the potential atherogenic effect of the ε4 allele and the protective effect of the ε2 allele based on lipid and inflammatory marker profiles. Conclusions This study provides strong evidence linking APOE gene polymorphism to abnormal serum lipid and inflammatory profiles. Individuals carrying the ε4 alleles exhibited dysregulated lipid metabolism and abnormal inflammatory markers, increasing their risk of CVD and AD. Early detection and prompt diagnosis are crucial for implementing therapeutic, dietary, and lifestyle interventions to mitigate risks and prevent or delay lipid and inflammation-related disorders.

Comparison of the Friedewald and Vujovic methods with the calculated LDL concentration in a biochemical auto-analyzer.

To compare the concentration of Low-Density Lipoprotein (LDL-c) obtained using the Friedewald formula with those obtained directly with the RAYTO CHEMRAY 120 autoanalyzer. Cross-sectional study. We evaluated outpatients with a medical request for a lipid profile study (total cholesterol, triglycerides, LDL, and HDL). The analyses were carried out in a RAYTO CHEMRAY 120 autoanalyzer under the principle of spectrophotometry. We obtained LDL-c using the Friedewald and Vujovic formulas. We evaluated 199 individuals whose direct LDL concentration averages were measured by the RAYTO CHEMRAY 120 equipment. Those calculated by the Friedewald and Vujovic formulas were 129.97 ± 32.66, 119.28 ± 30.44, and 127.01 ± 32.01, respectively, and in all cases, significant differences (P < 0.001) were observed with the RAYTO analyzer. In both cases a low positive bias was found with the RAYTO analyzer.. The Passing-Bablok and Deming's regressions showed a linear correlation between both methods (Friedewald and Vujovic) with the LDL values obtained with the Rayto autoanalyzer. Our study found that the Friedewald and Vujovic methods are good predictors of LDL cholesterol levels and have a low level of bias. Therefore, they could be used as potential predictors.

Supplementation of Salvia hispanica L. seed ameliorated liver function enzymes, hyperlipidemia, and oxidative stress in high fat diet fed Swiss albino mice

BackgroundSalvia hispanica L. (Chia) seed improves liver marker enzymes, lipid profile and antioxidant enzyme activity. PurposeThe aim of the research work was to evaluate the hepatic and antioxidant enzymes activity of chia seed supplementation in high fat diet fed mice. MethodsLiver marker enzymes, lipid profile, oxidative stress, antioxidant enzyme activity, and histology were evaluated for chia seed supplementation in high fat diet fed mice. Here, ALT, AST, and ALP were done for liver marker enzymes test. Cholesterol, triglyceride, HDL, and LDL were measured for lipid profiles. MDA, NO, AOPP, and MPO were done for oxidative stress test. Catalase and SOD were performed for measuring antioxidant enzyme activity. Hematoxylin and eosin and Prussian blue staining were done for histology purposes. ResultsIn high fat diet fed mice liver marker enzymes were significantly reduced by supplementation of chia seed. Lipid profiles like cholesterol, triglyceride, LDL concentration were declined and HDL concentration was increased significantly by chia seed supplementation in high fat diet fed mice. High fat diet increased oxidative stress markers such as MDA, NO, AOPP, and MPO which was significantly decreased by the supplementation of chia seed. Antioxidant enzyme activity and histology were also improved by the supplementation of chia seed. ConclusionAccording to this study, chia seed supplementation can reduce liver fibrosis, hyperlipidemia, oxidative stress, and improve antioxidant enzyme activity in mice fed a high-fat diet.

Purple Sweet Potato Extract and Aerobic Exercise Reduce Lipid Profiles in Hyperlipidemic Rats Model

Obesity and dyslipidemia are the major risk factors for cardiovascular disease. It has been shown that dietary supplementation combined with exercise at appropriate intensity improves lipid profile and reduces the risk of cardiovascular disease. This study investigates the effect of purple sweet potato extract and swimming training on the lipid profile of a hyperlipidemic rat model. Twenty-five male Wistar rats were grouped into standard diet and high-fat diet and given their respective diet for two weeks. Afterward, they were randomly divided into five weight-matched groups; normal control (C; n=5), high-fat diet (HF; n=5), exercise (E; n=5), purple sweet potato extract (PSP; n=5), and exercise combined with purple sweet potato extract (EPSP; n=5). Purple sweet potato extract was given 100 mg/day through oral gavage for three weeks. Swimming exercise was performed for 30 minutes/day, five days a week, for three weeks at an intensity of 6% of body weight. At the end of the experimental period, intracardiac blood samples were drawn to measure lipid profiles. Data analysis technique using a one-way ANOVA test with a significant level of 5%. The findings revealed that the concentration of TC and LDL was highest in HF. The combination of exercise and purple sweet potato extract significantly reduced LDL and increased HDL levels compared to exercise or PSP alone (p ≤ 0.05). It indicates that purple sweet potato extract combined with swimming exercise is shown to be effective in improving lipid profiles in hyperlipidemic rat models. Keyword: Aerobic exercise, hyperlipidemia, lipid profile, purple sweet potato.

Metabolic biomarkers in patients with type 2 diabetes mellitus and heart failure with preserved ejection fraction

BACKGROUND: Half of all patients with chronic heart failure (CHF) have preserved ejection fraction (CHF-nEF). The drug’s use effective for treatment of CHF with reduced ejection fraction (CHF-nFV) reduces the hospitalization incidence but does not affect the cardiovascular incidence or overall mortality in patients with CHF-nFV. Finding differences between CSN-SFV and CSN-nFV biomarkers is a pressing scientific problem.AIM: To study the metabolic disorders biomarkers intergenic relationships, myocardial damage, and to evaluate their role in the CHF development in patients with DM2.MATERIALS AND METHODS: We studied the lipid and carbohydrate metabolism disorder genes polymorphisms frequencies in patients with CHF-CFV and DM2 (48 patients), CHF-NFV and DM2 (46) and patients with metabolic syndrome (MS) without CHF (68), mean age of patients was 69,7±5,3 yo. DNA was isolated from venous blood according to the manufacturer’s methodology. Gene polymorphisms were determined by real time PCR. The studied polymorphisms correlations with clinical and laboratory data and associations between clinical and laboratory tests were identified by regression analysis.RESULTS: In the control group, PPARG, APOC3 C3238G rs5128, LIPC -250 G&gt;A rs2070895, APOA1 G-75A rs670, FABP2 Ala54Thr G&gt;A rs1799883, ADRB2 5318 C&gt;G rs1042714 genes polymorphisms, along with co-dependent ADRB3, FTO, FABP2 genes polymorphic form a gene network regulating plasma concentrations of LDL, uric acid and CAD. Gene polymorphisms have been found to be associated with clinical and/or laboratory parameters in patients with CHF-CFV: PPARGC1AGly482Ser G&gt;A rs8192678 with CAD; PPARGT-2821C rs12497191 with glycated hemoglobin level; FTO A&gt;T rs9939609 (α-ketoglutarate dependent dioxygenase gene) with waist circumference; LEPR A&gt;G rs1137101 (leptin receptor gene) with MAP. The following polymorphisms were found to be associated in patients with CHF-nFV: LIPC-250 G&gt;A rs2070895 (liver triglyceride lipase gene) with MAP; PPARGC1A Gly482Ser G&gt;A rs8192678 with MAP; FTO A&gt;T rs9939609 with waist volume.CONCLUSIONS: From the study results, it is evident that patients with DM2 having CHF with different PV differ significantly among themselves by the presence of polymorphic genes prone to network interactions. The greatest number of such interactions is observed in the group of CHF-sFV, which determines a more complex course of this variant of CHF than in patients with CHF-nFV.

Could Tumor Necrosis Factor Serve as a Marker for Cardiovascular Risk Factors and Left Ventricular Hypertrophy in Patients with Early-Onset Coronary Artery Disease?

Introduction: Tumor necrosis factor (TNF), a pro-inflammatory cytokine, can be produced by cardiomyocytes, leading to metabolic disorders in the myocardium. The objective of this study was to assess the relationship between plasma levels of the TNF cytokine and the presence of known biochemical and clinical risk factors for cardiovascular disease, along with the parameters of cardiac morphology in patients diagnosed with coronary artery disease (CAD) at a young age. Materials and Methods: The study group included 75 men aged up to 50 years and 25 women aged up to 55 years. The plasma TNF concentration was measured by use of the ELISA assay. Echocardiography and electrocardiographic examinations were performed in all patients. Results: We observed positive correlations for TNF with the BMI ratio, weight, waist and hip circumference. We also found negative correlations for TNF with HDL levels and ApoA concentrations, and positive correlations with the ApoB/ApoA1 ratio, Apo B, IL6, LDL and TG concentrations. These results suggest an association between higher plasma TNF concentrations and components of metabolic syndrome, including dyslipidemia. TNF may be a potential risk factor for impaired diastolic function. Conclusions: While TNF may be useful for diagnosing certain risks in CAD patients, the TNF measurement cannot be used as a surrogate test for echocardiography.
