Association of elevated lipoprotein(a) levels with ischemic stroke in young patients - a systematic review and meta-analysis

IntroductionLipoprotein(a) [Lp(a)] is an established independent causal risk factor for cardiovascular disease and atherosclerosis. However, its association with young-onset ischemic stroke is not well-established. A systematic review and meta-analysis was performed to investigate the association of elevated Lp(a) with young ischemic stroke. MethodsFour electronic databases: PubMed (MEDLINE), EMBASE, Scopus and Cochrane Library were systematically searched, profiling studies from inception till 6 Mar 2024. We included studies investigating the relationship between stratified Lp(a) levels and young ischemic stroke. We compared the odds of young stroke patients (age <65 years) having elevated Lp(a) compared to age-matched controls without stroke or transient ischemic attack. ResultsFive case-control studies comprising a total of 1345 patients were included; 57.7 % (776/1345) were females, with a mean age of 41.5 years. Among them, 22.5 % (264/1171) were smokers. Additionally, 16.8 % (197/1171) had hypertension, 5.9 % (69/1171) had diabetes, and 29.2 % (284/971) had hyperlipidemia. Young stroke patients were more likely to have high Lp(a) level than age-matched controls (OR 1.61, 95 %CI 1.24–2.10). Four studies defined a high Lp(a) level as ≥30mg/dL, whilst one study used a Lp(a) level of >23.2mg/dL as the cut-off. A sensitivity analysis excluding this study showed that young stroke patients were still more likely to have Lp(a) ≥30mg/dL than controls (OR 1.43, 95 %CI 1.08–1.88). ConclusionYoung stroke patients are more likely to have elevated Lp(a) compared to age-matched controls, suggesting an association between elevated Lp(a) and young stroke. Further research is warranted to evaluate the causal relationships between Lp(a) and young-onset ischemic stroke, as well as to conduct a cost-benefit analysis of Lp(a) screening in young adults as part of a primary prevention strategy.

Hyperhomocysteinemia-Induced Alterations in Protein Expression and Oxidative Stress Parameters in Rat Heart

Hyperhomocysteinemia (HHcy) is considered an independent risk factor of cardiovascular diseases. Among the proposed mechanisms underlying homocysteine toxicity are altered protein expression and induction of oxidative stress. In the present study, we explored protein abundance and parameters related to oxidative stress in heart homogenates of rats exposed to chronic mild HHcy. Using two-dimensional gel electrophoresis followed by MALDI-TOF/TOF mass spectrometry 22 altered proteins (6 upregulated and 14 downregulated) were identified. For eight proteins the altered abundances were validated by Western blot analysis. Identified proteins are primarily involved in energy metabolism (mainly enzymes of glycolysis, pyruvate dehydrogenase complex, citric acid cycle, and ATP synthase), cardiac muscle contraction (α-actin and myosin light chains), stress response (heat-shock protein β1 and αB-crystallin) and antioxidant defense (glutathione peroxidase 1). Diminished antioxidant defense was confirmed by decreases in total antioxidant capacity and GSH/GSSG ratio. Consistent with the decline in enzymatic and non-enzymatic antioxidant defense the protein oxidative modification, as determined by tyrosine nitration, was significantly increased. These findings suggest that both, altered protein expression and elevated oxidative stress contribute to cardiovascular injury caused by HHcy.

Distribution of cardiovascular disease risk factors between hypertensive and normotensive adults in Garissa County, Kenya

Background: Cardiovascular diseases (CVDs) are diseases affecting the heart and the blood vessels. Globally hypertension is the leading cause of cardiovascular disease and premature death, affecting 26% of the world population with prevalence expected to rise to 29% by 2025. The main study outcome was the distribution of cardiovascular disease risk factors. Secondary outcomes were the knowledge and socio-economic factors and their impact on distribution of cardiovascular disease risk factors. Methods: This was a retrospective case control study. Information regarding the sociodemographic, cardiovascular disease risk factors, knowledge and socioeconomic factors were collected from 140 adult patients (70 hypertensives and 70 normotensives) seeking outpatient services in Garissa County, Kenya. The 95% confidence limit was used and findings whose p≤0.05 was considered statistically significant. Results: Majority of the participants were aged &gt;65 years (28.6%), followed by 56-65 years (24.3%) with a range of 25-75 years and were mainly male (57.1%), had attained at least a primary school education level (39.3%) and employed (53.6%). The prevalence of increased cardiovascular disease risk factors (&gt;3 CVD risk factors) was 72.1% among the study participants with the hypertensive arm having 14.9% higher prevalence. There was statistically significant association between BMI and knowledge with distribution of cardiovascular disease risk factors (p=0.01) and (p=0.05) respectively. Conclusions: The hypertensive arm had marginally higher cardiovascular disease risk factors. High BMI and low knowledge were both associated with increased cardiovascular disease risk factors. Prospective studies with larger sample size and encompassing more counties are recommendable.

Boroxazolidones: Synthesis, In Silico and In Vitro Evaluation as ACE/AChE Dual Inhibitors, and In Vivo Testing of Antihypertensive Activity.

Systemic arterial hypertension is a serious chronic health problem caused by multiple factors. It is a major risk factor for Cardiovascular Diseases (CVDs), including heart failure, coronary heart disease, and myocardial infarction. Hypertension can be effectively treated with inhibitors of the Angiotensin Converting Enzyme (ACE), such as captopril, enalapril, and lisinopril. However, these drugs are associated with significant adverse reactions (e.g., persistent coughing, skin rashes, and angioedema). Considering the recent insights obtained by our group into the antihypertensive effect of boroxazolidones, the aim of the current contribution was to design and synthesize a series of these compounds derived from α-amino acids and evaluate them (in silico and in vitro) as inhibitors of ACE and acetylcholinesterase (AChE). The best candidates were examined for their in vivo antihypertensive activity to regulate high blood pressure in male spontaneously hypertensive rats. Although boron-containing compounds were once thought to be toxic in any medical context, they have increasingly been used as antibiotics, antiseptics, and antineoplastic agents. BXZHis, BXZ-Lys, BXZ-Orn, BXZ-Phe, and BXZ-Pro were selected in silico as promising ACE and AChE inhibitors. After synthesis, these molecules were tested in vitro as ACE and AChE inhibitors, finding that most were effective at micromolar concentrations. The two best candidates, BXZ-Lys and BXZ-His, were evaluated in vivo with spontaneously hypertensive rats. BXZ-Lys significantly decreased systolic, diastolic, and mean blood pressure, being more potent than a common ACE inhibitor, captopril. Future research is required to elucidate the mechanism of action of this antihypertensive effect.

Therapeutic Efficacy of Selenium Pre-treatment in Mitigating Cadmium-Induced Cardiotoxicity in Zebrafish (Danio rerio)

Cardiovascular diseases are a rampant public health threat. Environmental contaminants, such as Cadmium (Cd), a toxic metal, are risk factors for cardiovascular diseases. Given that human exposure to Cd is increasing, there is a need for therapies to ameliorate Cd toxicity. Selenium (Se), an essential trace element, has been proposed to rescue the effects of Cd toxicity, with mixed effects. Se's narrow therapeutic window necessitates precise dosing to avoid toxicity. Here, we assessed the effects of various waterborne Cd and Se concentrations and sequences on cardiac function using zebrafish (Danio rerio). We showed that Cd induced pericardial edemas and modified heart rates in zebrafish larvae in a concentration-dependent manner. To identify the therapeutic range of Se for Cd-induced cardiotoxicity, zebrafish embryos were treated with 0, 10, 50, 100, 150, or 200 μg/L Se for 1–4 days prior to exposure to 2.5 and 5 μg/L Cd. We found that a 50 µg/L Se pre-treatment before 2.5 μg/L Cd, but not 5 μg/L Cd, reduced the prevalence of pericardial edemas and ameliorated Cd-induced bradycardia in zebrafish. Zebrafish exposed to 10 and 50 μg/L of Se for up to 4 days showed typical heart morphology, whereas other Se-exposed and control fish presented pericardial edemas. Longer Se pre-treatment durations led to fewer incidences of pericardial edemas. Overall, this study highlights the importance of optimizing Se concentrations and pre-treatment periods to harness its protective effects against Cd-induced cardiotoxicity. These findings provide insights into potential therapeutic strategies for reducing Cd-related cardiovascular damage in humans.Graphical

Integration of network pharmacology, UHPLC-Q exactive orbitrap HRMS technique and metabolomics to elucidate the active ingredients and mechanisms of compound danshen pills in treating hypercholesterolemic rats

Ethnopharmacological relevanceHypercholesterolemia (HLC) was a key risk factor for cardiovascular disease (CVD) characterized by elevated cholesterol levels, particularly LDL. While traditional Chinese medicine preparations Compound Danshen Pills(CDP) has been clinically used for hypercholesterolemia and coronary heart disease, its specific therapeutic effect on HLC remains understudied, necessitating further investigation into its mechanisms. Aim of the studyThe aim of this study was to explore the potential of CDP in treating HLC and elucidate its underlying mechanisms and active components. Materials and methodsA hypercholesterolemic lipemia rat model induced by a high-fat diet was employed. Network pharmacology combined with UHPLC-Q exactive orbitrap HRMS technique was used to predict the active components, targets and mechanisms of CDP for HLC. Histological analysis and serum biochemical assays were used to assess the therapeutic effect of CDP and its main active ingredient Sa B on hypercholesterolemic lipemia rat model. Immunofluorescence assays and western blotting were used to verify the mechanism of CDP and Sa B in the treatment of HLC. Metabolomics approach was used to demonstrate that CDP and Sa B affected the metabolic profile of HLC. ResultsOur findings demonstrated that both CDP and its main active ingredient Sa B significantly ameliorated hypercholesterolemic lipemic lesions, reducing levels of TC, LDL, AST, ALT, and ALP. Histological analysis revealed a decrease in lipid droplet accumulation and collagen fiber deposition in the liver, as well as reduced collagen fiber deposition in the aorta. Network pharmacology predicted potential targets such as PPARα and CYP27A1. Immunofluorescence assays and western blotting confirmed that CDP and Sa B upregulated the expression of Adipor1, PPARα and CYP27A1. Metabolomics analyses further indicated improvements in ABC transporters metabolic pathways, with differential metabolites such as riboflavin, taurine, and choline showed regression in levels after CDP treatment and riboflavin, L-Threonine, Thiamine, L-Leucine, and Adenosine showed improved expression after Sa B treatment. ConclusionCDP and Sa B have been shown to alleviate high-fat diet-induced hypercholesterolemia by activating the PPAR pathway and improving hepatic lipid metabolism. Our study demonstrated, for the first time, the complex mechanism of CDP, Sa B in the treatment of hypercholesterolemia at the protein and metabolic levels and provided a new reference that could elucidate the pharmacological effects of traditional Chinese medicine on hypercholesterolemia from multiple perspectives.

The Buddy System: African American Women with Self-Reported Hypertension and Their Experiences in a Peer (Dyadic) Support Intervention

INTRODUCTION: Hypertension is the leading modifiable risk factor for cardiovascular disease, and it disproportionately affects African American women, who face increased risks of heart disease, kidney disease, and stroke. The Dietary Approaches to Stop Hypertension (DASH) diet effectively reduces blood pressure, but African American women often face challenges with adhering to it. Peer support, a proven mechanism for improving health behaviors through social connections and community resources, may help these women better manage their diet and hypertension. This qualitative study explored the experiences of African American women participating in an eight-week peer (dyadic) support intervention to improve DASH diet adherence and lowering systolic blood pressure, with an emphasis on understanding the dyadic relationship. METHODS: A purposive sample of 40 African American women (20 dyads) was recruited for five focus groups that were conducted both online and in person. Content analysis was used to identify themes related to the nature and quality of peer interactions and relationships from the perspectives of the 34 women who completed the intervention (Mean age = 71.38 years; SD = 8.38). RESULTS: Four subthemes emerged: emotional support, shared experiences, informational/inspirational support, and accountability. The participants reported forming strong, supportive relationships that were crucial in improving diet and blood pressure management. CONCLUSION: This study underscores the benefits of peer support in managing hypertension among older African American women, suggesting the need for future randomized controlled trials to examine the effectiveness of the DASH diet with and without peer support.

Cardiovascular disease risk in people of African ancestry with HIV in the United Kingdom.

Our objective was to describe the prevalence of cardiovascular disease (CVD) risk factors in people of African ancestry with HIV in the UK. We conducted a cross-sectional analysis of CVD risk factors in Black people with HIV aged ≥40 years and estimated the 10-year CVD risk using QRISK®3-2018. Correlations between body mass index (BMI) and CVD risk factors were described using Pearson correlation coefficients, and factors associated with 10-year CVD risk ≥5% were described using logistic regression. We included 833 Black people with HIV and a median age of 54 years; 54% were female, 50% were living with obesity (BMI ≥30 kg/m2), 61% had hypertension, and 19% had diabetes mellitus. CVD risk >5% ranged from 2% in female participants aged 40-49 years to 99% in men aged ≥60 years, and use of statins ranged from 7% in those with CVD risk <2.5% to 64% in those with CVD risk ≥20%. BMI was correlated (R2 0.1-0.2) with triglycerides and diastolic blood pressure in women and with glycated haemoglobin, systolic and diastolic blood pressure, and total:high-density lipoprotein (HDL) cholesterol ratio in men. In both female and male participants, older age, blood pressure, diabetes mellitus, and kidney disease were strongly associated with CVD risk ≥5%, whereas obesity, total:HDL cholesterol, triglycerides, and smoking status were variably associated with CVD risk ≥5%. We report a high burden of CVD risk factors, including obesity, hypertension, and diabetes mellitus, in people of African ancestry with HIV in the UK. BMI-focused interventions in these populations may improve CVD risk while also addressing other important health issues.

Exploring the interplay between kidney function and urinary metabolites in young adults: the African-PREDICT study

The exposure to modifiable risk factors at young ages have been linked to premature fatal and non-fatal cardiovascular and kidney outcomes. The use of urinary metabolomics has shown strong predictability of kidney function and cardiovascular disease (CVD). We therefore determined the associations between estimated glomerular filtration rate (eGFR) and urinary metabolites in young adults with and without CVD risk factors. Apparently healthy Black and White sexes were included (aged 20–30 years) and categorised by the presence or absence of risk factors, i.e., obesity, physical inactivity, smoking, excessive alcohol intake, masked hypertension, hyperglycemia, dyslipidemia and low socio-economic status, forming the CVD risk group (N = 1036), CVD risk clusters (i.e. presenting with 1 CVD risk factor (N = 344), 2 CVD risk factors (N = 360) and 3 + CVD risk factors (N = 332)) and the control group (N = 166). eGFR was calculated with CKD-EPI equations. A targeted metabolomics approach using liquid chromatography-tandem mass spectrometry was used to measure amino acids and acylcarnitines. Lower cystatin C-based eGFR were indicated in the CVD risk group, 2 and 3 + CVD risk clusters compared to the control group (all P ≤ 0.033). In the CVD risk group, eGFR associated positively with histidine, lysine, asparagine, glycine, serine, glutamine, dimethylglycine, threonine, alanine, creatine, cystine, methionine, tyrosine, pyroglutamic acid, leucine/isoleucine, aspartic acid, tryptophan, glutamic acid, free carnitine, acetylcarnitine, propionylcarnitine, isovalerylcarnitine, octanoylcarnitine and decanoylcarnitine (all P ≤ 0.044), with similar results found in the CVD risk clusters, particularly the 2 CVD risk cluster. eGFR was positively associated with metabolites linked to aromatic amino acid and branched-chain amino acid metabolism, energy metabolism and oxidative stress. These findings may indicate altered reabsorption of these metabolites or altered metabolic regulation to preserve renal health in the setting of CVD risk factors at this young age without established CVD.

Variations in antihypertensive medication treatment and blood pressure control among Veterans with HIV and existing hypertension

BackgroundHypertension is a leading risk factor for cardiovascular disease among patients living with HIV (PLWH). Understanding the predictors and patterns of antihypertensive medication prescription and blood pressure (BP) control among PLWH with hypertension (HTN) is important to improve the primary prevention efforts for this high-risk population. We sought to assess important patient-level correlates (eg, race) and inter-facility variations in antihypertension medication prescriptions and BP control among Veterans living with HIV (VLWH) and HTN. MethodsWe studied VLWH with a diagnosis of HTN who received care in the Veterans Health Administration (VHA) from January 2018 to December 2019. We evaluated HTN treatment and blood pressure control across demographic variables, including race, and by medical comorbidities. Data were also compared among VHA facilities. Predictors of HTN treatment and control were assessed in 2-level hierarchical multivariate logistic regression models to estimate odds ratios (ORs). The VHA facility random-effects parameters from the hierarchical models were used to calculate the median odds ratios to characterize the variation across the different VHA facilities. ResultsA total of 17,468 VLWH with HTN (mean age 61 years, 97% male, 54% Black, 40% White) who received care within the VHA facilities in 2018-2019 were included. 73% were prescribed antihypertension medications with higher prescription rates among Black vs White patients (75% vs 71%) and higher prescription rates among patients with a history of cardiovascular disease, diabetes, and kidney disease (>80%), and those receiving antiretroviral therapy and with controlled HIV viral load (∼75%). Only 27% of VLWH with HTN had optimal BP control of systolic BP <130 mmHg and diastolic BP <80 mmHg, with a lower rate of control among Black vs White patients (24% v. 31%). In multivariate regression, Black patients had a higher likelihood of HTN medication prescription (OR 1.32, 95% CI: 1.22-1.42) but were less likely to have optimal BP control (OR 0.82; 0.76-0.88). Important positive correlates of antihypertensive prescription and optimal BP control included: number of outpatient visits in prior year, and histories of diabetes, coronary artery disease, and heart failure. There was about 10% variability in both antihypertensive prescription and BP control patterns between VHA facilities for patients with similar characteristics. There was increased inter-facility variation in antihypertensive prescription among those with a history of heart failure and those not receiving antiretroviral therapy. ConclusionIn a retrospective analysis of large VHA data, we found that VLWH with HTN have suboptimal antihypertensive medication prescription and BP control. Black VLWH had higher HTN medication prescription rates but lower optimal BP control.

Benefits of SGLT2 inhibitors on renal and cardiovascular protection, in diabetic patients

Introduction: Type 2 Diabetes Mellitus is major risk factors for both cardiovascular and renal diseases. Managing cardiovascular risk and the progression of renal disease is therefore essential in treating diabetic patient. Sodium-glucose cotransporter-2 inhibitors have been linked to a substantial decrease in cardiovascular and renal mortality, reduced hospitalizations for heart failure and slower progression of renal damage and albuminuria. Objectives: Our study aimed to evaluate the impact of SGLT2i on cardiovascular and renal protection in diabetic patients. Methods: Our study involved elderly patients, with type 2 diabetes, who were divided in two groups, one group received SGLT2i, while the other did not. Data were collected at the start of treatment, as well as at 3, 6, 9 and 12 months thereafter. During each evaluation, we assessed HbA1C, BMI, GFR and renal parameters, uric acid, NTproBNP, echocardiography, and both PAS and PAD values, in both groups. Results: Out of 300 elderly diabetic patients included in the study, 200 were started on dapagliflozin 10 mg. At 12 months, HbA1c, weight, systolic blood pressure, NTproBNP, uric acid, albuminuria, were decreases in group with dapagliflozin versus the other group without it, and estimated glomerular filtration rate was higher (75.3 – 87.19mL/min/1.73m2; p&lt;0.005). Follow up in patients with SGLT2i showed a significant decrease in left ventricular end-diastolic dimension (LV-EDD) (62.86 mm to 54.85 mm; P&lt; 0.001) and improvement in LV-EF. Conclusions: The use of Dapagliflozin demonstrated metabolic benefits in patients with T2DM, including notable decreases in HbA1c, blood pressure, weight, uric acid, and NTproBNP. Additionally, cardiovascular and renal benefits were observed. Therefore, SGLT2i have a significant impact on both cardiovascular and renal protection in diabetic patients.

Awareness of cholesterol levels in 46,309 Italian children and adolescents unveils the tip of the iceberg.

Cardiovascular diseases (CVD) risk factors include high cholesterol. Childrenwith total cholesterol (TC) levels ≥ 170mg/dLare usually considered hypercholesterolemic. This study aimed at investigating the awareness of TC levels in a large Italian paediatric population and at looking for a possible correlation between their TC and TC in their parents' blood. A survey was carried out in 46,309 subjects (mean age 9.7 ± 2.3years; age range 6-14years) to check the awareness of their own TC levels by using a personal and family medical history questionnaire. In 95.67% of the sample TC value was unknown. In 2.69% TC was < 170mg/dL, whereas 1.64% were hypercholesterolemic (TC ≥ 170mg/dL). A statistically significant correlation was found between children with normal TC values and physiological TC values in both parents (p < 0.0001). Again, a significant association between children with high TC and their parents with high TC was detected when parents were analysed separately (i.e. children with TC ≥ 170mg/dl vs maternal TC ≥ 200mg/dL: OR 2.01 (95% CI 1.61-2.49, p < 0.001); children with TC ≥ 200mg/dl vs maternal TC ≥ 240mg/dL: OR 3.14 (95% CI 2.14-4.6, p < 0.001); children with TC ≥ 170mg/dl vs paternal TC ≥ 200mg/dL: OR 2.39 (95% CI 1.91-2.98, p < 0.001); children with TC ≥ 200mg/dl vs paternal TC ≥ 240mg/dL: OR 3.85 (95% CI 2.70-5,.50, p < 0.001). Just a minority of the investigated young patients knew their TC. This is worrisome. Children with normal TC values are more likely to be born from healthy parents with physiological TC. In addition, high TC in the enrolled subjects is significantly associated with high TC in their parents. Overall, these findings seem to highlight the importance of health education and genetics in TC pathogenesis.

The combined impact of migraine and gestational diabetes on long-term risk of premature myocardial infarction and stroke: A population-based cohort study.

To examine the combined impact of migraine and gestational diabetes mellitus (GDM) on the risks of premature (persons aged ≤60 years) major adverse cardiovascular and cerebrovascular events (MACCE) based on a composite endpoint of fatal and non-fatal myocardial infarction (MI) and stroke. Migraine and GDM are risk factors for cardiovascular disease. It is unknown how the combination of migraine and GDM may affect cardiovascular disease risk. In a Danish population-based cohort longitudinal study, we established four cohorts among women with at least one pregnancy during 1996-2018: women with migraine, women with GDM, women with both migraine and GDM, and women free of migraine and free of GDM. Risks of premature MACCE and component endpoints were assessed for each cohort. We included 1,307,456 women free of migraine and free of GDM, 56,811 women with migraine, 24,700 women with GDM, and 1484 women with migraine and GDM. The 20-year absolute risk of MACCE was 1.3% (MI: 0.4%, ischemic stroke: 0.6%, hemorrhagic stroke: 0.3%) among women free of migraine and free of GDM, 2.3% (MI: 0.8%, ischemic stroke: 1.2%, hemorrhagic stroke: 0.5%) among women with migraine, 2.2% (MI: 1.0%, ischemic stroke: 1.0%, hemorrhagic stroke: 0.4%) among women with GDM, and 3.7% (MI: 1.7%, ischemic stroke: 1.7%, hemorrhagic stroke: 0.3%) among women with both migraine and GDM. The 20-year adjusted hazard ratio of premature MACCE was 1.65 (95% confidence interval [CI] 1.49-1.82) for women with migraine; 1.64 (95% CI 1.37-1.96) for women with GDM; and 2.35 (95% CI 1.03-5.36) for women with both GDM and migraine when compared with women free of migraine and free of GDM. Migraine and GDM were each independently associated with an increased risk of MACCE. Risk of premature MACCE was greatest among women with both migraine and GDM, although this risk estimate was imprecise.

Public health and system approach in eliminating disparities in hypertensive disorders and cardiovascular outcomes in non-Hispanic Black women across the pregnancy life course

Hypertension is one of the leading risk factors for cardiovascular disease. The ACC/AHA/Multisociety hypertension guideline covered all aspects of the recommendations for optimal blood pressure diagnosis and management to improve cardiovascular outcomes. Despite this, there remains a growing prevalence of hypertension within the United States, largely in non-Hispanic Black women at earlier stages of their life course. This highlights the evident racial disparities, but offers a targeted opportunity for improved outcomes. With hypertension increasingly seen in the antenatal and immediate postpartum period, and obstetrics societies weighing in on the need to alter pharmacotherapy initiation goals, national initiatives have purposefully targeted pregnant and postpartum women in an effort to improve outcomes. This same energy must also re-focus health care efforts across the entire health continuum. Public health and system strategies are in place to do so, with the strongest enforcing initiatives as early as childhood with a greater focus on primordial prevention.

Association between serum remnant cholesterol level and metabolic dysfunction-associated steatotic liver histology.

Estimated remnant cholesterol (Rem-C) level, a risk factor for cardiovascular disease (CVD), is associated with metabolic dysfunction-associated steatotic liver disease (MASLD) diagnosed via ultrasonography. However, the relationship between accurate serum Rem-C level measurements and histological findings of MASLD remains unclear. We aimed to elucidate the relationship between accurately measured serum Rem-C levels and histological findings of MASLD. Cross-sectional single-center observational study. We assessed 222 patients (94 men and 128 women; age 20-80) who were diagnosed with MASLD via liver biopsy with available medical history, physical examination, and biochemical measurement data. Serum ester-type cholesterol and free cholesterol contents in the remnant lipoproteins were measured using an enzymatic method. Serum Rem-C levels were significantly higher in patients with NAFLD activity score (NAS) 5-8, ＞66% steatosis grade, lobular inflammation with ≥5 foci, and many cells/prominent ballooning cells (a contiguous patch of hepatocytes showing prominent ballooning injury) than in patients with NAS 1-4, <33% steatosis grade, lobular inflammation with <2 foci, and few ballooning cells (several scattered balloon cells), respectively. While univariate analysis revealed no significant association between Rem-C levels and advanced fibrosis, a significant association between Rem-C levels and NAS was evident. This relationship remained significant in multivariate analysis adjusted for confounders. Furthermore, in the analysis by sex, these relationships were significant for men but not for women. High serum Rem-C levels were associated with high NAS, but not with fibrosis stage, particularly in men. Controlling serum Rem-C level may improve MASLD activity.

Synergistic effects of glucose tolerance and BMI on cardiovascular events and all-cause mortality in a healthy population: CA.ME.LI.A study 7 years follow-up.

The CA.ME.LI.A (CArdiovascular risks, MEtabolic syndrome, LIver and Autoimmune disease) epidemiological study was conducted in Abbiategrasso (Milan, Italy) to identify risk factors for metabolic and cardiovascular disease in an apparently healthy population of northern Italy. The population (n = 2,545, 1,251 men, 1,254 women) was stratified according to body mass index [normal body weight (NBW): <25 kg/m2; overweight-obese (OWO): ≥25 kg/m2] and according to fasting blood glucose [normal fasting glucose: <100 mg/dL; impaired fasting glucose (IFG): 100-125 mg/dL; diabetes mellitus (DM): ≥126 mg/dL]. The incidence of cardiovascular (CV) events and overall mortality were studied by the Kaplan-Meier method using the log rank test. Univariate analysis was conducted with time-dependent Cox models. During the 7-yr follow-up period, 80 deaths and 149 CV events occurred. IFG [hazard ratio (HR): 2.81; confidence interval (CI): 1.37-5.77; P = 0.005], DM (HR: 4.88; CI: 1.47-16; P = 0.010), or OWO (HR: 2.78; CI:1.68-4.59; P < 0.001) all produced significant increases in CV events and deaths. In the combination IFG/OWO (HR: 5.51; CI: 3.34-9.08; P < 0.001), there was an apparent additive effect of the two conditions, whereas in the combination DM/OWO (HR: 12.71; CI: 7.48-22; P < 0.001), there was an apparent multiplicative effect on the risk for CV events and deaths. In males, the DM/NBW group had a higher incidence of cardiovascular events and deaths than the IFG/OWO group. In contrast, in females, the IFG/OWO group had a higher incidence of cardiovascular events and deaths than the DM/NBW group. In women, there was a greater incidence of CV events in the IFG/OWO group (HR: 6.23; CI: 2.88-13; P < 0.001) than in men in the same group (HR: 4.27; CI: 2.15-8.47; P < 0.001). Consistent with these data, also all-cause mortality was progressively increased by IFG/DM and OWO, with an apparently exponential effect in the combination DM/OWO (HR: 11.78; CI: 6.11-23; P < 0.001). IFG/DM and OWO, alone or in combination, had major effects in increasing mortality for all causes and CV events. The relative contributions of hyperglycemia and overweight/obesity on cardiovascular events and deaths were apparently, to a certain extent, sex dependent. Females were more affected by overweight/obesity either alone or combined with IFG, as compared with males.NEW & NOTEWORTHY For the first time, the combined effects of glucose tolerance and BMI have been investigated in an apparently healthy large population sample of a city in the north of Italy. We found that there are synergistic effects of glucose levels with BMI to increase not only cardiovascular events and deaths but also cancer-related deaths and all-cause mortality.

Exploring the cardiovascular health behaviors of college students and the areas that need increased public health efforts.

Cardiovascular disease (CVD) is a leading cause of death worldwide among adults. Traditionally, the disease has been considered as a condition affecting older adults. However, its risk factors (e.g., poor diet, sedentary behavior, inadequate sleep, and obesity) are increasingly being identified in younger populations. There is a need to increase the evidence of CVD risk factors in this population to further support preventive programs in this demographic. This study investigates the prevalence of CVD risk factors in young adult, college students. Data was used from the American College Health Association's National College Health Assessment (ACHA-NCHA) II-C. The sample included data from 426,259 students, ages 18-25. Data was reviewed on race, nutrition, physical activity, tobacco use, sleep, weight, and history of chronic disease. Descriptive statistics were utilized to examine the prevalence of CVD risk factors. There was a notable prevalence of CVD risk factors, such as insufficient nutrition, obesity, insufficient physical activity, and inadequate sleep, among college students. CVD-related risk factors are on the rise within this demographic. There is a pressing need for the expansion of public health initiatives aimed at enhancing CVD awareness and prevention among college students.

Effectiveness of cascade screening for elevated lipoprotein(a), an underdiagnosed family disorder.

Elevated lipoprotein(a) [Lp(a)] is a prevalent, independent, genetic risk factor for cardiovascular disease. Though crucial for adequate risk assessment, detection of individuals at increased risk because of elevated Lp(a) is severely lacking in practice. In this light, several consensus statements have recommended familial cascade screening strategies to increase detection of elevated Lp(a). This review aims to synthesize findings from recent research into the effectiveness of cascade screening for elevated Lp(a). Cascade screening is an effective method for identifying individuals with elevated Lp(a) and is superior to opportunistic screening. Cascade screening identifies approximately one new case of elevated Lp(a) ≥ 125 nmol/L for every two first-degree relatives screened. The number needed to screen (NNS) ranged from 1.3 to 2.9, depending on Lp(a) threshold values and selected population. Cascade screening appears to be a promising strategy for identifying individuals with elevated Lp(a). However, several challenges persist regarding the implementation of this strategy in clinical practice. Deciding on threshold values for initiating cascade screening, considering the implications of ethnicity-related variability of Lp(a) levels, and further research into the clinical relevance of cascade screening are crucial steps. Understanding these factors will be essential for optimizing cascade screening protocols and enhancing its effectiveness in clinical practice. http://links.lww.com/COL/A31.

Assessment of glycemic control and correlation of HbA1c level with lipid profile and duration of diabetes in type 2 diabetes mellitus patients

Background &amp; Objectives: The prevalence of Type 2 diabetes mellitus, or Type 2 DM, is rising globally. A periodic estimation of HbA1c has been recommended to track the state of glycemic control of Type 2 DM patients, in order to control the diabetes associated disorders. The main consequence and cause of death in Type 2 diabetes has been identified as cardiovascular disease (CVD).Optimization of glycemic status along with decreasing CVD risk factors are critical to preventing morbidity and mortality in patients with Type 2 DM. Since there is a lack of data on these CVD risk factors, in Madhesh Province, Nepal, we aimed to evaluate the glycemic status, estimate the lipid profile, and ascertain their correlation, including duration of Type 2 DM among patients in tertiary care hospitals in Madhesh Province, Nepal. Materials and Methods: The tertiary care hospital based cross-sectional study was conducted on 139 Type 2 DM patients, in Madhesh Province, Nepal. In order to gather information of the participants, a systematic questionnaire was introduced. A physical and clinical examination was performed, and an appropriate volume of blood was drawn with prior written consent. The lipid profile parameters, HbA1C, Fasting and post prandial serum glucose were estimated. Results: In 84 (60.3%) and 106 (76.3%) cases, there was an increased fasting and postprandial blood sugar. The mean±SD HbA1c level was 8.40±0.8%. More than half (52.5%) of the patients had poor glycemic control, while 22.3% had inadequate glycemic control, in reference to HbA1c &gt;8% and 7 to 8%, respectively. A substantial increased level of LDL-C, triglycerides and total cholesterol was observed in 122 patients and 85.6% had reduced HDL-C. A significant strong positive association was found between HbA1c level and total cholesterol and triglycerides, in contrast, no discernible association with duration of disease observed. Conclusion: Glycemic control was inadequate. Triglycerides and total cholesterol were significantly positively correlated with HbA1c, but not with HDL-C, LDL-C, or the course of diabetes.
