Higher High-density Lipoprotein Levels Research Articles

High-Density Lipoprotein Correlates with Cognitive Functioning in Schizophrenic Women.

(1) Background: Schizophrenia is a chronic and progressive neuropsychiatric illness. Apart from positive and negative symptoms, 98% of the population diagnosed with schizophrenia have impaired cognitive functioning, which significantly influences the quality of life. The correlation between lipids and cognitive functioning has been well established. Our study aimed to investigate correlations between cognitive functions, the severity of schizophrenia symptoms, and lipid profiles. (2) Methods: Fifty-two women diagnosed with schizophrenia participated in this study. Cognitive functioning was measured using the Wisconsin Card Sorting Test (WCST). The Positive and Negative Symptom Scale (PANSS) was used. The serum lipid profile, including low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and triglycerides was measured. (3) Results: Better cognitive functions were associated with normal HDL levels, while low HDL levels correlated with worse WSCT scores. Only the PANSS negative subscale showed a correlation with HDL levels. Correlations with chronicity of schizophrenia and the patient's age with poorer cognitive functions, but not with symptom severity, were detected. Early/late age at onset did not influence WSCT scores. (4) Conclusions: Our results suggest high HDL levels might be a protective factor against cognitive impairment. The influences of age and illness duration also play a vital role in cognitive performance.

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.

Serum Levels of Adiponectin Are Strongly Associated with Lipoprotein Subclasses in Healthy Volunteers but Not in Patients with Metabolic Syndrome.

Metabolic syndrome (MS) is a widespread disease in developed countries, accompanied, among others, by decreased adiponectin serum levels and perturbed lipoprotein metabolism. The associations between the serum levels of adiponectin and lipoproteins have been extensively studied in the past under healthy conditions, yet it remains unexplored whether the observed associations also exist in patients with MS. Therefore, in the present study, we analyzed the serum levels of lipoprotein subclasses using nuclear magnetic resonance spectroscopy and examined their associations with the serum levels of adiponectin in patients with MS in comparison with healthy volunteers (HVs). In the HVs, the serum levels of adiponectin were significantly negatively correlated with the serum levels of large buoyant-, very-low-density lipoprotein, and intermediate-density lipoprotein, as well as small dense low-density lipoprotein (LDL) and significantly positively correlated with large buoyant high-density lipoprotein (HDL). In patients with MS, however, adiponectin was only significantly correlated with the serum levels of phospholipids in total HDL and large buoyant LDL. As revealed through logistic regression and orthogonal partial least-squares discriminant analyses, high adiponectin serum levels were associated with low levels of small dense LDL and high levels of large buoyant HDL in the HVs as well as high levels of large buoyant LDL and total HDL in patients with MS. We conclude that the presence of MS weakens or abolishes the strong associations between adiponectin and the lipoprotein parameters observed in HVs and disturbs the complex interplay between adiponectin and lipoprotein metabolism.

Metabolic effects of Type 2 Diabetes mellitus might be mitigated by grape pomace flour

Type 2 diabetes mellitus (T2DM) is a multifaceted metabolic disorder characterized by insulin resistance and pancreatic β-cell dysfunction, leading to varying metabolic insults. Grape pomace, a byproduct of the winemaking industry, is under investigation as a potential therapy for T2DM due to its abundant content of bioactive polyphenols and dietary fiber. Within the current backdrop of environmental concerns, the conversion of grape pomace into a safe and applicable form, with the aim of promoting sustainable management of environmental waste, acts as a catalyst for the emergence of viable alternatives. Grape pomace flour (GPF) represents an economical and feasible solution. We hypothesized that dietary supplementation of GPF would improve the glycemic control and the associated risk factors in T2DM-induced animals. In this sense, the present study, approved by CEUA UFPel No 033578/2022-14, aimed to evaluate the effect of the GPF from ‘Arinto’ and ‘Touriga Nacional’ grape varieties on biochemical and histopathological parameters in an animal model of T2DM. To induce T2DM, rats were given a high-fat diet and a Streptozotocin (STZ) injection (35 mg/kg). The rats were divided into five groups: Control (CT), T2DM, T2DM+Metformin (Met) (250 mg/kg), T2DM+'Arinto' GPF 10% (WGPF), and T2DM+'Touriga Nacional' GPF 10% (RGPF). Results showed that Met, WGPF, and RGPF groups had significantly lower blood glucose ( p<0.05, P<0.001, and p<0.01, respectively) and triglyceride levels ( p<0.001) compared to the T2DM group. Also, we observed a significant increase in serum cholesterol levels in the T2DM when compared to the CT ( p<0.01), that was reversed in the treated groups. Additionally, the T2DM+RGPF group had higher levels of high-density lipoprotein (HDL) compared to the control group ( p<0.05). Histopathological analysis revealed structural changes in the pancreas in the T2DM animals, while tissue damage was not observed in the Met and GPF supplementation groups. In conclusion, both 'Arinto' and 'Touriga Nacional' GPF demonstrated protective effects against increased blood glucose, triglycerides, and cholesterol levels in a T2DM animal model. 'Touriga Nacional' GPF also increased HDL levels and showed protective effects on pancreatic cell structure. This suggests that GPF could be a promising dietary option for T2DM and its complications.

Exploring the bi-directional relationship between periodontitis and dyslipidemia: a comprehensive systematic review and meta-analysis.

As periodontitis and dyslipidemia are diseases that occur with high incidence, the relationship between them has attracted much attention. Previous studies on these diseases have tended to focus on lipid parameters and periodontitis, we aimed to investigate the relationship between dyslipidemia and periodontitis. A comprehensive search to identify the studies investigating the relationship between dyslipidemia and periodontitis was performed on PubMed, Web of Science and Cochrane Library before the date of August, 2023. Studies were considered eligible if they contained data on abnormal blood lipid parameters and periodontitis. Studies that reported mean differences and 95% confidence intervals or odds ratios were used. A total of 73 publications were included in the meta-analysis. Hyper total cholesterol (TC), triglycerides (TGs), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and lower high-density lipoprotein (HDL) levels are risk factors for periodontitis. Periodontal disease is a risk factor for high TG and low HDL levels. Three months after periodontal treatment, the levels of TC, TG and HDL were significantly improved, and statin treatment only improved gingival index (GI) levels compared to that of the dietary control. The findings reported here suggest that the mutual promotion of periodontitis and dyslipidemia can be confirmed. Non-surgical periodontal therapy may improve lipid abnormalities. It can't be demonstrated whether systematic application of statins have a better effect on the improvement in periodontal status in patients with dyslipidemia compared to that of the control.

Metabolic Profile and Long-Term Risk of Depression, Anxiety, and Stress-Related Disorders

Biomarkers of lipid, apolipoprotein, and carbohydrate metabolism have been previously suggested to be associated with the risk for depression, anxiety, and stress-related disorders, but results are inconsistent. To examine whether the biomarkers of carbohydrate, lipid, and apolipoprotein metabolism are associated with the risk of depression, anxiety, and stress-related disorders. This population-based cohort study with longitudinal data collection assessed 211 200 participants from the Apolipoprotein-Related Mortality Risk (AMORIS) cohort who underwent occupational health screening between January 1, 1985, and December 31, 1996, mainly in the Stockholm region in Sweden. Statistical analysis was performed during 2022 to 2023. Lipid, apolipoprotein, and carbohydrate biomarkers measured in blood. The associations between biomarker levels and the risk of developing depression, anxiety, and stress-related disorders through the end of 2020 were examined using Cox proportional hazards regression models. In addition, nested case-control analyses were conducted within the cohort, including all incident cases of depression, anxiety, and stress-related disorders, and up to 10 control individuals per case who were individually matched to the case by year of birth, sex, and year of enrollment to the AMORIS cohort, using incidence density sampling. Population trajectories were used to illustrate the temporal trends in biomarker levels for cases and controls. A total of 211 200 individuals (mean [SD] age at first biomarker measurement, 42.1 [12.6] years; 122 535 [58.0%] male; 188 895 [89.4%] born in Sweden) participated in the study. During a mean (SD) follow-up of 21.0 (6.7) years, a total of 16 256 individuals were diagnosed with depression, anxiety, or stress-related disorders. High levels of glucose (hazard ratio [HR], 1.30; 95% CI, 1.20-1.41) and triglycerides (HR, 1.15; 95% CI, 1.10-1.20) were associated with an increased subsequent risk of all tested psychiatric disorders, whereas high levels of high-density lipoprotein (HR, 0.88; 95% CI, 0.80-0.97) were associated with a reduced risk. These results were similar for male and female participants as well as for all tested disorders. The nested case-control analyses demonstrated that patients with depression, anxiety, or stress-related disorders had higher levels of glucose, triglycerides, and total cholesterol during the 20 years preceding diagnosis, as well as higher levels of apolipoprotein A-I and apolipoprotein B during the 10 years preceding diagnosis, compared with control participants. In this cohort study of more than 200 000 participants, high levels of glucose and triglycerides and low levels of high-density lipoprotein were associated with future risk of depression, anxiety, and stress-related disorders. These findings may support closer follow-up of individuals with metabolic dysregulations for the prevention and diagnosis of psychiatric disorders.

A Study to Observe the Impact of Depression, Anxiety, and Stress Levels on the Cardiovascular Profile in Elderly Patients Attending a Peripheral Medical College of a Developing Country

Background: Cardiovascular disease is one of the leading causes of death worldwide, more so in an aging population with mental health issues. Objectives: We aimed to study the influence of depression, anxiety, and stress levels on the cardiovascular profile in elderly patients attending a peripheral medical college in West Bengal. Methodology and Participants: This cross-sectional study was conducted in a peripheral medical college among 197 elderly participants. The cardiovascular profile was examined and Depression, Anxiety, and Stress Scale-21 scores were estimated. Results: One hundred and thirty-four (68%) were male and 63 (32%) were female and male–female participants were age and body mass index (BMI) matched. Males had significantly higher waist/hip ratio, heart rates, systolic blood pressure (BP), and diastolic BP. The female population demonstrated significantly higher levels of high-density lipoprotein (HDL), whereas males had higher levels of total cholesterol, triglycerides, and very low-density lipoprotein (VLDL) cholesterol. One hundred and third-eight (70.1%) had normal electrocardiogram findings, 30 (15.2%) had left axis deviation, 13 (6.6%) had right axis deviation, and 16 (8.2%) had ischemic heart disease. The mean ± standard deviation (SD) score of depression for males was 10.66 ± 6.81 and for females 16.22 ± 7.17 (P < 0.0001). The mean ± SD of the stress score for males was 10.67 ± 6.71 and for females 15.17 ± 6.45 (P < 0.001). BMI, heart rate, triglyceride, VLDL, and low-density lipoprotein (LDL) cholesterol showed a significant positive correlation with depression scores. A significant positive correlation was observed between anxiety scores and waist/hip ratio. Stress scores had significant positive correlations with age, triglyceride, LDL, and VLDL levels and a negative correlation with HDL levels. Conclusions: Increased depression anxiety and stress levels were found to worsen the cardiovascular profile among the elderly population and more so among males.

Comparative Effects of Fermented and Unfermented Parkia biglobosa Bean Seeds in Diabetic Induced Experimental Rats

Aims: The present work investigates the hypoglycemic effect of fermented seeds of Parkia biglobosa (PB, African locust beans) in alloxan-induced diabetic rats. Its effect was compared with that of unfermented Parkia biglobosa.
 Methodology: In order to assess the hypoglycemic effects of the fermented seeds on experimental animals, fasting blood sugar (FBS), total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were determined. The microbiota analysis of the fecal sample was also determined.
 Result: Alloxan administered to the rats significantly increased the FBS of the test animals. However, dietary supplementation with fermented PB for three weeks ameliorated the FBS of the rats like that of the unfermented group. The animals fed with fermented Parkia biglobosa gained weight like those fed with unfermented Parkia biglobosa. High levels of HDL and low levels of LDL were observed in animals treated with fermented Parkia biglobosa compared with low levels of HDL and high levels of LDL observed in animals treated with unfermented Parkia biglobosa.
 Conclusion: The results of this present study demonstrate that both fermented and unfermented seeds of Parkia biglobosa exert a hypoglycemic effect. Hence, Parkia biglobosa has an anti-diabetic property with fermented form seemingly better.

Establishing non-fasting reference values for plasma lipids levels based on age, sex, and puberty stage in a French-Canadian pediatric population

BackgroundDyslipidemias, including familial hypercholesterolemia (FH), are a significant risk factor for cardiovascular diseases. FH is a genetic disorder resulting in elevated levels of low-density lipoprotein cholesterol (LDL-C) and an increased probability of early cardiovascular disorders. Heterozygous familial hypercholesterolemia (HeFH) is the most common form, affecting approximately 1 in 250 individuals worldwide, with a higher prevalence among the French-Canadian population. Childhood is a critical period for screening risk factors, but the recommendation for non-fasting screening remains controversial due to a lack of specific reference values for this state. This study aims to establish reference values for lipid levels in non-fasting children from Sherbrooke, Quebec, Canada, that will be specific for sex, age, and pubertal stages.MethodsBlood samples and corresponding anthropometric data were collected from 356 healthy children aged from 6 to 13. They were categorized either into two age groups: Cohort 6–8 and Cohort 9–13, or into pubertal stages. Reference values, specifically the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentiles were determined using the CLSI C28-A3 guidelines.ResultsLipid profiles did not significantly differ between sexes, except for higher levels of high-density lipoprotein (HDL-C) in boys within Cohort 6–8. HDL-C levels significantly increased, while LDL-C and non-HDL-C levels significantly decreased in both sexes with age. Non-fasting age- and pubertal stages-specific reference values were established.ConclusionThis study established reference intervals for lipid markers in non-fasting state within the pediatric French-Canadian population. These findings could be used in dyslipidemia screening in daily practice.

The prevalence and correlates of biomarker positive unhealthy alcohol use among women living with and without HIV in San Francisco, California.

The objective of this study was to identify the prevalence and correlates of phosphatidylethanol (PEth) levels suggestive of unhealthy alcohol use among women living with and without HIV who self-reported no or low-risk drinking. We analyzed data from a cross-sectional study among women enrolled in the San Francisco Bay Area site of the Women's Interagency HIV Study (WIHS). Between October 2017 and March 2018, PEth was tested from dried blood spots in 192 women enrolled in the San Francisco site of the WIHS. Using multivariable logistic regression, we identified the correlates of PEth levels suggestive of unhealthy alcohol use (>50 ng/ml) among the 168 women who reported no or low-risk drinking (<7 drinks per week) in the past six months, while controlling for age in years and race/ethnicity. Among the 168 women in the analysis sample, the median age was 55; 51% identified as Black/African American, 47% were living with HIV and 28% had PEth levels ≥50 ng/ml which are suggestive of unhealthy alcohol use. Factors independently associated with PEth levels ≥50 ng/ml in adjusted models were: identifying as Black/African American (adjusted odds ratio [aOR] = 8.34, 95% CI = 2.06-33.72), having an alanine transaminase to aspartate aminotransferase ratio > 1 (aOR = 3.10, 95% CI = 1.18-8.13), higher high-density lipoprotein levels (aOR = 1.31 per 10 mg/dL increase, 95% CI = 1.01-1.70), and consuming a greater number of drinks per week in the past six months (aOR = 1.40, 95% CI = 1.10-1.78). Nearly a third of women in this study had PEth levels suggestive of unhealthy alcohol use and potentially under-reported their use. To optimize alcohol related health care, there is a need to consider approaches to improve ascertainment of unhealthy alcohol use, especially among Black/African American women and those living with liver disease, so that interventions can be initiated.

Significance of monitoring the levels of thyroid hormone antibodies and glucose and lipid metabolism antibodies in patients suffer from type 2 diabetes.

The association of thyroid hormone antibodies and glycolipid metabolism indicators with Type 2 diabetes mellitus (T2DM) was explored. As the disease worsens, the levels of thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPOAb), and thyroid-stimulating hormone (TSH) was increased, and the levels of total tri-iodothyronine (TT3) and total thyroxine (TT4) was decreased (P < 0.001). The severe, medium, and light group had higher level of high-density lipoprotein (HDL), lower level of total cholesterol (TC), low-density lipoprotein (LDL), glycosylated hemoglobin (HbA1c), triacylglycerol (TAG), and fasting blood sugar (FBG) than the control group (P ＜ 0.05). The level of HDL was lower in the severe group than the light group and the medium group, but the levels of TC, LDL, HbA1c, TAG, and FBG were increased with the progress of T2DM (P ＜ 0.001). The levels of TGAb, TPOAb, and TSH in patients with T2DM were positively correlated with the levels of TC, LDL, HbA1c, TAG, and FBG (P < 0.05), and were negatively correlated with HDL levels (P < 0.05). The life quality score was lower in the severe group than the light and the medium group (P < 0.001). Among the above indicators, the predictive value of TT3, TT4, and HbA1c in T2DM was better. Clinically, detecting the levels of thyroid hormone antibodies and glycolipid metabolism indicators had a certain predictive value for the severity of T2DM. Main findings: The results of this study found that the thyroid hormone antibody and glycolipid metabolism levels in T2DM patients were abnormal, and had different degrees of impact on the quality of life of patients. Thus, monitoring these indicators had certain predictive value for the severity of the disease, and also had a certain degree of suggestive effect on the evaluation of diabetic vascular complications. Clinically, attention should be paid to the screening of thyroid disease in diabetic patients, and the assessment and prognosis of thyroid function on diabetes, the control of diabetes, and the prevention and treatment of complications have important clinical significance.

Association between osteoporosis and cardiovascular disease in elderly people: evidence from a retrospective study

Objective This study aimed to investigate the associations between osteoporosis, biochemical indexes, bone mineral density (BMD), and cardiovascular disease. Methods A cross-sectional study design was used to examine the relationships between these parameters. Logistic regression and correlation analyses were conducted to assess the associations between elevated levels of triglyceride, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), homocysteine, and the presence of osteoporosis. Additionally, correlations between BMD and biochemical indexes were analyzed. The incidence of cardiovascular disease and its correlation with BMD were evaluated. Receiver operating characteristic (ROC) analysis was performed to determine the utility of BMD in identifying cardiovascular disease. Results The results revealed that elevated triglyceride, total cholesterol, and LDL levels were positively associated with osteoporosis, while higher HDL levels and homocysteine were negatively associated. Correlation analysis demonstrated negative correlations between triglyceride levels and BMD, and positive correlations between total cholesterol and HDL levels with BMD. LDL levels showed a weak negative correlation, and homocysteine levels exhibited a strong negative correlation with BMD. The osteoporosis group had lower BMD and a higher incidence of cardiovascular disease compared to the non-osteoporosis group. Logistic regression analysis confirmed the correlation between lower BMD and increased risk of cardiovascular disease. Conclusion This study provides evidence supporting the associations between osteoporosis, biochemical indexes, BMD, and cardiovascular disease. Aberrations in lipid profiles and homocysteine levels may contribute to osteoporosis development. Lower BMD, particularly in individuals with osteoporosis, appears to increase the risk of cardiovascular disease. BMD shows promise as a diagnostic tool for identifying individuals at risk of cardiovascular disease. Further research is needed to elucidate the underlying mechanisms and establish the clinical implications of these relationships. Future longitudinal studies are necessary to determine causality and long-term prognostic implications.

Serum high-density lipoprotein level and prognosis of ovarian cancer.

This study aimed to investigate the prognostic value of serum high-density lipoprotein (HDL) level in patients with ovarian cancer. This study enrolled 152 patients diagnosed with ovarian cancer and 119 patients with benign ovarian tumors. The associations of patient characteristics and disease with survival were determined using Cox regression analysis, t tests, analysis of variance for multiple-group comparisons, and chi-square tests. The potential association between HDL levels and the clinical characteristics of the disease was also analyzed. The diagnostic value of HDL was estimated using receiver operating characteristic curve analysis and calculation of the area under the curve. Progression-free survival and overall survival were determined using the Kaplan-Meier method, and their associations with patient and pathological variables, including HDL, were determined using the log-rank test. The median serum HDL was 1.15 mm measured in 152 patients with ovarian cancer and 1.30 mm in 119 patients with benign ovarian tumors (P = .000054). The receiver operating characteristic curve analysis yielded an area under the curve of 0.735 for serum HDL levels. Serum HDL levels were significantly associated with tumor pathological types (non-serous vs serous, P < .05). No association was observed between serum HDL levels and patient age, age at menarche or marriage, number of children, tumor grade, or clinical stage (P > .05). Patients with high serum HDL levels had a longer progression-free survival and overall survival than those with low serum HDL levels. Serum HDL levels are an independent prognostic factor for ovarian cancer.

Diet quality indices and their relationship with dyslipidemia in adults: A cross-sectional study

Food habits may influence a range of modifiable risk factors of cardiovascular diseases (CVDs) including dyslipidemia. This study was conducted to find whether healthy eating index (HEI) and dietary quality index-international (DQI-I) were associated with the risk of dyslipidemia among the Iranian adults in Shiraz. In this study, 236 participants with the age of 20-50 years were recruited from Shiraz medical centers through random cluster sampling. The HEI-2015 and DQI-I scores were computed using dietary intakes based on a 168-item food frequency questionnaire (FFQ). Logistic regression was utilized to estimate the relation between HEI-2015 and DQI-I score and lipid profile. Individuals in the greatest adherence to the HEI-2015 was associated with reduced odds ratio (OR) of total cholesterol (TC) and low-density lipoprotein (LDL) in the crude model (OR: 0.46 and OR: 0.30). This association was significant after adjustment for potential confounders (OR: 0.40 and OR: 0.31). Also, we observed significant association between DQI-I with TC and LDL in crude model (OR: 0.42 and OR: 0.45). In the adjusted model, participants in the last tertile of DQI-I were 55%, 58% and 57% less likely to have abnormal TC (OR: 0.45), LDL (OR: 0.42) and high-density lipoprotein (HDL) (OR: 0.43), compared those in the first tertile. In conclusion, higher adherence to DQI-I score was related to lower LDL and total cholesterol and higher HDL levels. Furthermore, in participants with higher adherence of HEI-2015 score, LDL and total cholesterol level were lower.

Interplay between Lipid Profile and Weight-Related Outcomes in Healthy Overweight Adults: In-sights from Comprehensive Analyses

Background: The escalating prevalence of overweight and obesity has heightened concerns about cardiovascular health. The intricate interplay between lipid profile variables and weight-related outcomes plays a pivotal role in shaping cardiovascular risks among individuals with excess body weight. This study investigates the associations between lipid profile variables and weight-related indicators in a cohort of healthy, overweight adults, shedding light on potential implications for cardiovascular risk management. Methods: The prevalence of metabolic syndrome, risk factors, and related lifestyle in adult Myanmar citizens were examined in the Inter-University Consortium for Political and Social Research Study (ICPSR146521) using prospective data. The patient’s lipid profiles and demographic data were statistically analyzed using the statistical MedCalc tool. Statistical significance was determined using a 0.05 p-value. Results: Results demonstrate that while BMI is influenced by multiple factors beyond lipid profile variables, waist circumference exhibits moderate association with these variables. Notably, triglycerides significantly correlated with waist circumference, suggesting a potential role in visceral fat accumulation. Additionally, the study highlights the impact of high-density lipoprotein (HDL) cholesterol levels on body weight, indicating that higher HDL levels are associated with lower body weights among healthy overweight adults. Conclusion: This study provides comprehensive insights into the complex relationship between lipid profile variables and weight-related outcomes among healthy, overweight adults. These findings underscore the importance of weight management strategies for cardiovascular health and suggest potential avenues for targeted interventions. By understanding the interplay between lipid profiles and obesity, clinicians and public health professionals can develop more effective strategies to mitigate cardiovascular risks in this demographic

Associations between neighborhood socioeconomic deprivation, IFNγ, and high-density lipoprotein particle size: Data from the Washington, D.C. cardiovascular health and needs assessment

IntroductionNeighborhood socioeconomic deprivation is associated with increased cardiovascular risk factors, including inflammation. Inflammation plays an important role in modifying the cardioprotective function of high-density lipoprotein (HDL). Moreover, recent studies suggest that very high HDL is associated with adverse cardiovascular disease (CVD) outcomes. Thus, we sought to explore the relationships between neighborhood socioeconomic deprivation as a marker of chronic stress, inflammation, proprotein convertase subtilisin/kexin type 9 (PCSK9) (a core component of the HDL proteome), HDL characterisitcs, and biological aging as a predictor of CVD and all-cause mortality. MethodsSixty African American subjects were recruited to the NIH Clinical Center as part of a community-based participatory research-designed observational study. Neighborhood deprivation index (NDI), a marker of neighborhood socioeconomic deprivation, was measured using US Census data. HDL characteristics (cholesterol, particle number, size, subspecies) were determined from NMR lipoprotein profiling, and plasma cytokines (IL-1β, IL-6, IL-8, TNFα, IFNγ) were measured using an ELISA-based multiplex technique. Epigenetic clock biomarkers of aging were measured using DNA methylation data obtained from participants' buffy coat samples. We used linear regression modeling adjusted for atherosclerotic cardiovascular disease (ASCVD) risk score, body mass index (BMI), and lipid-lowering medication use to investigate relationships of interest. ResultsNDI directly associated with large HDL particle count (H7P) and IFNγ and trended toward significance with HDL-C and PCSK9. IFNγ and PCSK9 then directly associated with H7P. H7P also directly associated with higher DNA methylation phenotypic age (PhenoAge). ConclusionWe highlight associations between neighborhood socioeconomic deprivation, IFNγ, PCSK9, HDL subspecies, and epigenetic biomarkers of aging. Taken together, our findings suggest indirect pathways linking neighborhood deprivation-related stress and inflammation to HDL and immune epigenetic changes. Moreover, these results add to recent work showing the pathogenicity of high HDL levels and underscore the need to understand how chronic stress-related inflammation and lipoprotein subspecies relate to CVD risk across diverse populations.

Association between a Marine Healing Program and Metabolic Syndrome Components and Mental Health Indicators.

Background and Objectives: Metabolic syndrome is a growing health concern globally, and its prevalence continues to increase. This study investigated whether a marine healing program could improve metabolic syndrome indicators and mental health in adults with a metabolic syndrome and those at risk of developing it. Materials and Methods: This study enrolled 30 participants who were assigned to either the experimental or control groups. The duration of the study was set at 4 weeks. Both groups received metabolic syndrome management education, and the experimental group additionally participated in two marine healing programs. Anthropometric indicators, biochemical indicators, and mental health indicators were collected before and after the intervention. Results: The findings indicate that the experimental group had significantly lower systolic blood pressure, triglycerides, and body weight, as well as higher levels of high-density lipoprotein (HDL-C) and uric acid. Mental health indicators (Hospital Anxiety and Depression Scale and quality of life measures) additionally showed improvement. Pre-post comparisons between the experimental group and the control group showed that the experimental group had significantly decreased by 1.05 kg in body weight, whereas the control group increased by 0.29 kg in body weight. In addition, HDL-C decreased by 0.91 mg/dL in the control group and increased by 3.7 mg/dL in the experimental group. Conclusions: Overall, these results suggest that marine healing programs could improve metabolic syndrome indicators such as body weight and HDL-C better than the control treatment.

Effect of Avocado Consumption on Risk Factors of Cardiovascular Diseases: A Systematic Review and Meta-Analysis.

High cholesterol levels are a significant risk factor for heart disease, the leading cause of death worldwide. Lowering cholesterol plays a crucial role in maintaining good health. One approach to reducing cholesterol is through dietary modifications, and avocados have been recognized as a potential food choice for this purpose. Avocados are rich in monounsaturated fatty acids (MUFAs), fiber, and plant sterols, which have cholesterol-lowering effects. Incorporating avocados into a low-fat diet can be beneficial. This study design followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and conducted databases in Cochrane, SCOPUS, PubMed, and Web of Science up until May 2023, combining keywords related to avocados and cardiovascular diseases (CVDs). The study focused on randomized clinical trials (RCTs) and excluded observational studies, meta-analyses, surveys, abstracts, and reviews. Seven RCTs were included in the study, all reporting total cholesterol (TC) levels. The findings of the study showed that individuals who followed an avocado diet experienced reduced TC levels compared to those who followed a habitual diet or a low-fat diet. The avocado group exhibited lower TC levels compared to the control group in both the habitual diet and low-fat diet subgroups. When considering high-density lipoprotein (HDL) levels, the control group had higher HDL levels than the avocado group in the habitual diet subgroup, while the avocado group had higher HDL levels than the control group in the low-fat diet subgroup. In both the habitual diet and low-fat diet subgroups, the avocado group had lower levels of low-density lipoprotein (LDL) compared to the control group. The study concluded that incorporating avocados into the diet can be a beneficial dietary strategy for individuals aiming to lower their cholesterol levels and promote heart health. The avocado diet was associated with decreased LDL levels, but it did not significantly impact triglyceride (TG) levels or fasting glucose levels.

The Association of the Levels of High-Density Lipoprotein and Apolipoprotein A1 with SARS-CoV-2 Infection and COVID-19 Severity: An Analysis of the N3C Database.

This study analyzed data from the National COVID Cohort Collaborative (N3C) database to investigate whether high-density lipoprotein (HDL) and its major protein component, apolipoprotein A1 (apoA1), are associated with severe COVID-19 sequelae, specifically acute kidney injury (AKI) and severe COVID-19 disease as defined by the infection resulting in hospitalization, extracorporeal membrane oxygenation (ECMO), invasive ventilation, or death. Our study included a total of 1,415,302 subjects with HDL values and 3589 subjects with apoA1 values. Higher levels of both HDL and apoA1 were associated with a lower incidence of infection as well as a lower incidence of severe disease. Higher HDL levels were also associated with a lower incidence of developing AKI. Most comorbidities were negatively correlated with SARS-CoV-2 infection, presumably due to the behavioral changes that occurred as a result of the precautions taken by individuals with underlying comorbidities. The presence of comorbidities, however, was associated with developing severe COVID-19 disease and AKI. African American and Hispanic populations experienced worse outcomes, including a higher incidence of infection and the development of severe disease, as well as AKI. Smoking and being male were associated with a lower incidence of infection, while they were risk factors for the development of severe disease and AKI. The results on cholesterol and diabetes drugs warrant further research, given that the database included multiple drugs in each category impeding for analysis of specific medications. Despite the current limitations in the N3C data, this study is the first to investigate the roles of HDL and apoA1 on the outcomes of COVID-19 using the US population data.

Cardiorespiratory Endurance is Associated with Metabolic Syndrome Severity in Men

Maintaining a good level of fitness through regular exercise is essential for the treatment and prevention of metabolic syndrome (MS). However, the question of which components of physical fitness have the greatest impact remains controversial. We studied the relationship between cardiorespiratory endurance and MS severity z-score in men. The study involved 44 untrained men (38.7±5.6 years). Anthropometric parameters (height, weight, BMI), glucose level, triglyceride level, high-density lipoprotein level, blood pressure, and MS severity z-score were assessed. We also assessed the level of cardiorespiratory endurance in a 12-minute Cooper test. The results of our study showed an inverse relationship between the z-score of MS severity and cardiorespiratory endurance in men, which was (r=–0.84; p˂0.05). People in the highest quartile of cardiorespiratory endurance (quartile 1) had a significantly lower MS severity z-score compared to people in the lowest quartile of cardiorespiratory endurance (quartile 4) (p˂0.01). In addition, people who demonstrated the highest cardiorespiratory endurance (quartile 1) had statistically significantly lower fasting plasma glucose levels and abdominal girth (p˂0.05), as well as statistically significantly lower levels of triglycerides, systolic blood pressure and higher levels of high-density lipoprotein (p˂0.01) compared to people in the lowest quartile of cardiorespiratory endurance (quartile 4). The obtained data confirm the protective role of cardiorespiratory endurance against MS in men.
