Familial dyslipidemia (FD), particularly familial hypercholesterolemia (FH), is a major contributor to premature cardiovascular disease (CVD), especially in regions with high consanguinity and underutilized genetic screening, such as Egypt. This study aimed to assess clinical, biochemical, and genetic factors that differentiate FD patients with and without CVD, and to develop a composite risk score for individualized stratification. A cross-sectional study was conducted on 60 Egyptian patients aged 15-25 years with genetically confirmed FD, equally divided based on CVD status. All participants underwent detailed clinical assessment, lipid profiling, and targeted next-generation sequencing of LDLR, APOB, and PCSK9 genes. Missense variants were evaluated using SIFT, PolyPhen-2, CADD, and ΔΔG stability scores, and classified according to ACMG criteria. Compared to non-CVD patients, those with CVD had significantly higher triglyceride levels (median: 356.5 vs. 236.5 mg/dL; p < 0.001) and a higher frequency of heterozygous pathogenic LDLR variants (30.0% vs. 3.3%; p = 0.006), while homozygous variants were more common in non-CVD patients (26.7% vs. 0%; p = 0.002). Deleterious missense variants were notably more frequent in the CVD group (56.7% vs. 10.0%; p < 0.001). A 10-variable composite risk score integrating clinical, lipid, and bioinformatic predictors effectively distinguished high- and moderate-risk cases (AUC = 0.742; p = 0.022), with 89.5% sensitivity and 81.8% negative predictive value. The study highlights the importance of combining clinical and genomic data for early risk stratification and introduces a pragmatic tool for identifying high-risk youth in resource-limited, consanguineous populations.

Diabetes mellitus and dyslipidemia are major risk factors for atherosclerosis. Hypoechoic plaques, which indicate vulnerable or unstable plaques, may rupture and lead to ischemic stroke, cognitive impairment, increased adverse cardiac events, and even death. This study aimed to investigate the correlation between plasma lipid levels and the characteristics of atherosclerotic plaques in adult patients with type 2 diabetes mellitus. A retrospective analysis was conducted on adult patients with type 2 mellitus who were hospitalized in the Department of Endocrinology at Affiliated Hospital of Hebei University between January 2017 and December 2021.Patients were categorized into two groups based on arterial ultrasound results. Statistical analyses were performed to compare plasma lipid levels and plaque characteristics across the groups. 1) Statistically significant differences were observed among the two groups in terms of gender, hypertension, age, duration of diabetes mellitus, plaque location, triglycerides (TG),total cholesterol (TC), Apolipoprotein A1 (Apo A1),very-low-density lipoprotein (VLDL), VLDL/apolipoprotein B(ApoB), high-density lipoprotein cholesterol (HDL)/ApoA1 ( In clinical practice, the characteristics of atherosclerotic plaques and lipid profiles should be jointly evaluated to guide targeted treatment and effectively reduce the risk of atherosclerotic cardiovascular disease.

Ischemic stroke is frequently associated with symptomatic intracranial atherosclerotic stenosis (sICAS), is a leading cause of global disability and mortality. Current guidelines recommend dual antiplatelet and intensive statin therapies. Proprotein convertase subtilisin 9/kexin type 9 (PCSK9) inhibitors have emerged as a potent lipid-lowering therapy, potentially influenced by genetic variations, particularly in the CYP2C19 gene. This study at Xuzhou Central Hospital from January 2021 to December 2023 included 151 patients divided into a statin group (n = 73) and a PCSK9 inhibitor (PCSK9i) group (n = 78). It evaluated lipid profiles, inflammatory markers, neurological function, and clinical outcomes over a 180-day follow-up period, with additional analysis stratified by CYP2C19 genotype. The PCSK9i group demonstrated significant improvements in lipid parameters compared to the statin group, including greater reductions in low-density lipoprotein cholesterol (LDL-C) (p = 0.008), total cholesterol (TC) (p < 0.001), and triacylglycerols (TAG) (p = 0.041), along with apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) (both p < 0.001). Inflammatory markers, particularly interleukin-6 (IL-6), significantly reduced in the PCSK9i group (p < 0.001). In the PCSK9i group, CYP2C19 rapid metabolizers achieved greater reductions in LDL-C (p = 0.021), ApoB (p = 0.003), and IL-6 levels (p = 0.041) compared to slow metabolizers. Post-treatment modified Rankin Scale (mRS) scores were significantly lower in rapid metabolizers compared to slow metabolizers (p = 0.018), though clinical events occurred infrequently in both subgroups. This study demonstrates that PCSK9 inhibitor therapy combined with statins provides enhanced lipid-lowering and anti-inflammatory effects compared to statin monotherapy in sICAS patients. While the CYP2C19 genotype may influence specific treatment responses, particularly lipid parameters, its impact on clinical outcomes requires further investigation. Show less

Despite widespread use of high-intensity statins, ezetimibe, and proprotein convertase subtilisin/kexin type 9 inhibitors, substantial atherosclerotic cardiovascular disease risk persists, especially in people with heterozygous familial hypercholesterolemia or elevated lipoprotein(a) [Lp(a)] levels. Cholesteryl ester transfer protein (CETP) inhibitors block the transfer of hydrophobic cholesteryl esters from high-density lipoprotein to apolipoprotein B (apoB)-containing particles. This process raises high-density lipoprotein-C and lowers low-density lipoprotein-C, apoB, and Lp(a) levels. The first-generation of CETP inhibitors was limited by toxicity, neutral outcomes, or unfavorable pharmacokinetics. Obicetrapib is a next-generation amphipathic CETP inhibitor that selectively targets both CETP's hydrophobic and hydrophilic tunnels. It reduces low-density lipoprotein-C by about 30-51%, apoB by 20-33%, and Lp(a) by 30-57% without causing tissue accumulation or toxicity. Phase 3 trials (BROOKLYN, BROADWAY, TANDEM) show that obicetrapib is effective when added to maximized therapy, with a safety profile similar to placebo. Its consistent reduction of Lp(a) addresses an important unmet need. In addition to lowering atherogenic lipoproteins, early data suggest potential for neuroprotection, such as reductions in p-tau217 seen among APOE4 carriers. A 2025 pooled analysis offers initial evidence that major adverse cardiovascular events are reduced, as studied in the ongoing PREVAIL outcomes trial. This review covers CETP biology and tunnel mechanics, outcomes from earlier CETP inhibitor studies, obicetrapib's pharmacology, and current efficacy and safety data, and will clarify its potential place in lipid management today.

Patients with chronic kidney disease frequently exhibit abnormalities in their lipid metabolism. Confounding factors in observational studies often obscure the causal relationship between these 2 diseases. This study investigated the causal relationships between genetically predicted levels of 6 key lipid parameters (total cholesterol (TC), triglycerides (TG), HDL-C, low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB)) and circulating kidney injury molecule 1 (KIM-1) levels, using a comprehensive bidirectional Mendelian randomization (MR) analysis. Using genome-wide association study data, the primary analysis used the inverse-variance weighted (IVW) method, supported by MR-Egger regression and a weighted median estimator. Sensitivity analyses including heterogeneity, pleiotropy tests, leave-one-out, and reverse causality analyses were conducted. The IVW model revealed the following: TG (odds ratio (OR): 1.1843, 95% confidence interval (CI): 1.1178-1.2547, P = 9.5894e-09), TC (OR: 1.1096, 95% CI: 1.0178-1.2095, P = .0182), and ApoA1 (OR: 1.1820, 95% CI: 1.0741-1.3007, P = .0007) were found to have significant causal relationships with KIM-1, a biomarker of kidney tubular injury, and may be risk factors for renal tubular injury; No significant causal associations were observed between high-density lipoprotein cholesterol (HDL-C), (P = .2929), LDL-C (P = .2178), ApoB (P = .1836), and KIM-1; Horizontal pleiotropy was detected for ApoA1 (P = .0208). However, sensitivity analyses confirmed the robustness of the results after the removal of outliers; significant heterogeneity was observed across all lipid parameters (Cochran Q P < .05), which necessitated the use of random-effects IVW models; and reverse causality analyses (MR-Egger intercept P > .05, Steiger filtering) confirmed no evidence of reverse causation between lipid profiles and KIM-1. TG, HDL-C, and ApoA1 levels may be risk factors for renal tubular injury. However, no significant causal relationships were observed between HDL-C, LDL-C, and ApoB levels and renal tubular injury. To further explore the underlying mechanisms of the associations between TG, HDL-C, ApoA1, and KIM-1 and to inform lipid management strategies in tubulopathy-related conditions. Show less

Mercury (Hg) is a widespread environmental pollutant with known neurotoxic and cardiometabolic effects, and its influence on lipid metabolism during childhood remains insufficiently understood. Mitochondrial dysfunction is proposed as a potential mechanism linking Hg exposure to metabolic disruption. Mitochondrial DNA copy number (mtDNA-CN) is regarded as an indicator of mitochondrial biogenesis and functional capacity, where lower levels generally suggest mitochondrial damage or dysfunction. In contrast, ribosomal DNA (rDNA) and relative telomere length (RTL) reflect genomic stability and cellular aging. This study investigated the associations between blood Hg levels and serum lipid profiles in children and adolescents and assessed the mediating roles of mtDNA-CN, rDNA, and RTL. A cross-sectional study was performed among 352 children and adolescents aged 6–17 years in eastern China. Blood Hg levels were determined using inductively coupled plasma mass spectrometry (ICP-MS), and serum lipid markers, namely total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB), and lipoprotein(a), were assessed along with the genomic indicators such as mtDNA-CN, rDNA, and RTL. Multivariable linear regression and mediation analyses were conducted. Higher Hg levels were significantly related with increased TC (β = 0.144, Hg exposure in children and adolescents is linked to an atherogenic lipid profile, potentially through mitochondrial dysfunction. MtDNA-CN appears to be a sensitive molecular mediator of Hg-induced lipid disturbances, which highlights the relevance of mitochondrial health in early-life environmental epidemiology and cardiovascular risk prevention. The findings support early prevention strategies and environmentally focused health policies that reduce toxicant exposure and thus promote long-term cardiometabolic health in young populations.

The contribution of circulating group 3 innate lymphoid cells (ILC3s) to lipid dysregulation has remained poorly defined, and the mechanisms through which washed microbiota transplantation (WMT) improves lipid metabolism require further clarification. Peripheral ILC subsets and plasma IL-22 were assessed in hyperlipidemia patients and healthy controls. The lipid-lowering effects of WMT were evaluated in a prospective cohort without lipid-lowering medications. Gut microbial and plasma metabolite profiles before and after WMT were analyzed. A hyperlipidemic mouse model was used to determine whether healthy microbiota promote hepatic ILC3 homing via integrin α4. Hyperlipidemia was characterized by reduced circulating ILC3s, integrin α4 Hyperlipidemia is associated with depletion of circulating ILC3s and reduced IL-22. Restoration of ILC3 subsets and enhancement of integrin α4-dependent hepatic homing are achieved after WMT, accompanying improvements in lipid metabolism. Show less

Atherosclerosis, a chronic inflammatory disease, presents significant "residual risk" even with effective lipid-lowering therapies, primarily due to persistent vascular inflammation. Apolipoprotein B100 (ApoB100) acquires pro-inflammatory properties upon modification and binds to cell-surface enolase 1 (ENO1), an immune modulator upregulated in inflammatory conditions. This interaction induces inflammatory responses via NF-κB activation. Targeting the ApoB100-ENO1 interaction may offer a novel strategy to reduce vascular inflammation and atherosclerosis progression. We developed PP3m, a stabilized ApoB100-derived peptide, to selectively inhibit the ApoB100-ENO1 interaction. Single-cell RNA sequencing (scRNA-seq) data from human atherosclerotic plaques were reanalyzed to characterize ENO1 expression in myeloid cells. In vitro, PP3m's anti-inflammatory effects were evaluated across various macrophage models stimulated by diverse inflammatory stimuli. Outcomes included cytokine secretion, inflammatory gene expression, foam cell formation, oxidized low-density lipoprotein (oxLDL) uptake, and signaling pathways activation. In vivo, Ldlr scRNA-seq analysis revealed that human atherosclerotic plaques harbor significantly more ENO1 macrophages, with ENO1 expression enriched in CD68 The ApoB100-ENO1 axis is a critical driver of macrophage-mediated inflammation in atherosclerosis. The novel peptide PP3m effectively inhibits this interaction, reducing vascular inflammation and plaque progression without altering lipid levels. PP3m represents a promising therapeutic candidate for cardiovascular disease by targeting residual inflammatory risk through a lipid-independent mechanism. Show less

Cardiovascular disease (CVD) remains a major global health concern and a leading cause of morbidity and mortality worldwide. Early-diagnosis and prompt medical attention are crucial in managing and reducing overall impact on health-and-wellbeing, necessitating the development of innovative diagnostics, which transcend traditional methodologies. Raman spectroscopy uniquely provides molecular fingerprinting and structural information, offering insights into biochemical composition. Integration of Raman spectroscopy with advanced machine learning is established as a powerful clinical adjunct for point-of-care detection of CVDs. A non-invasive, label-free spectroscopic platform coupled with neural network algorithm, 'SKiNET' has been developed to accurately detect the biomolecular changes within plasma of CVD versus healthy cohorts, enabling rapid diagnosis and longer-term monitoring, where the real-time capabilities provide dynamic assessment of progression, aligning treatment strategies with evolving states. CVD has been detected and classified via SKiNET with 88.6 %-accuracy, 92.9 %-specificity and 85.1 %-sensitivity and with 83.8 %-accuracy. The hybrid RS-SKiNET bio-molecularly specific detection signposted a comprehensive panel of CVD-indicative biomarkers, including SIL-6, IL-9, LpA, ApoB, PCSK9 and NT-ProBNP, offering important insights into disease mechanisms and risk-stratification. This multidimensional technique holds potential for improved patient-and-healthcare management for CVDs, laying the platform toward high-throughput biomolecular profiling of CVD-indicative macromolecular biomarkers, particularly vital for widespread point-of-care diagnostics and monitoring.

Familial hypercholesterolaemia (FH) is an autosomal dominant genetic disorder, characterised by markedly elevated levels of low-density lipoprotein cholesterol (LDL-C) from birth, which confers a substantially increased risk of premature atherosclerotic cardiovascular disease (ASCVD). Pathogenic variants primarily occur in the genes encoding the low-density lipoprotein receptor (LDLR), apolipoprotein B (ApoB), low-density lipoprotein receptor adaptor protein 1 (LDLRAP1), or proprotein convertase subtilisin/kexin type 9 (PCSK9). Early diagnosis, based on clinical criteria, family history, and genetic testing, is imperative to promptly initiate aggressive therapeutic strategies. Standard treatment involves lifestyle modifications and high-intensity pharmacotherapy, primarily with statins, often in combination with ezetimibe. For patients who do not achieve their therapeutic goals or are intolerant, PCSK9 inhibitors represent a significant evolution in the treatment paradigm. In this article, we present a case of homozygous familial hypercholesterolaemia. Show less

To analyze the potential therapeutic value and mechanism of luteolin in age-related macular degeneration (AMD) using network pharmacology and cellular experiments. SHD-compound targets were retrieved from the TCMSP database, while AMD-related targets were extracted from OMIM and DisGeNET databases. Overlapping targets were identified via Venny 2.1. A PPI network was constructed using the STRING database, followed by functional enrichment analysis of overlapping targets via Metascape. Pharmacological networks were mapped using Cytoscape. For cellular experiments, the optimal concentration of luteolin was determined by CCK-8 assay. Human umbilical vein endothelial cells (HUVECs) were divided into: Control group (Without any intervention), Model group (VEGF165-induced model), and Treatment group (VEGF165-induced + luteolin). Angiogenesis was evaluated via scratch, transwell migration, invasion, and tube formation assays. VEGFA protein expression was assessed by Western blot. We identified 157 SHD-compound targets and 87 AMD-related targets, yielding 6 overlapping targets (ESR1, PON1, SOD1, APOB, VEGFA, IL6). PPI networks and enrichment analysis revealed that luteolin in SHD may inhibit AMD neovascularization via VEGFA signaling pathways. The concentration of luteolin (25 µmol/L) used in the experiments was selected based on the dose-response results. In vitro assays showed the Treatment group exhibited: significantly reduced horizontal migration (scratch assay, p < 0.05), decreased vertical migration (transwell assay, p < 0.05), suppressed invasion (p < 0.05), and inhibited tube formation (p < 0.05). Western blot confirmed reduced VEGFA expression in the treatment group (p < 0.05). Luteolin alleviates angiogenesis in HUVECs by inhibiting VEGFA expression, highlighting its potential as a therapeutic candidate for neovascular AMD. Show less

Lipid-lowering therapy is typically initiated at high low-density lipoprotein(LDL) cholesterol marked by elevated apolipoprotein B(apoB). We tested the hypothesis that elevated apoB alternatively due to high remnant cholesterol confers equally high risk of atherosclerotic cardiovascular disease(ASCVD) but less initiation of lipid-lowering therapy, compared to elevated apoB due to high LDL cholesterol. From the Copenhagen General Population Study, 94 299 lipid-lowering therapy naïve adults without a history of ASCVD were included in 2003-2015. Discordance groups were formed by median levels of remnant cholesterol, LDL cholesterol and apoB. In the national Danish health registries, individuals were followed for a prescription of lipid-lowering therapy and for incident ASCVD until December 2021. During a median follow-up of 12 years, 9269 developed ASCVD. Compared to individuals with concordant low values of remnant cholesterol, apoB, and LDL cholesterol, those with high remnant cholesterol and high apoB but low LDL cholesterol had a hazard ratio(HR) of 1.45 (95% confidence interval: 1.34-1.56) for ASCVD and an odds ratio(OR) of 3.0 (2.5-3.6) for starting lipid-lowering therapy within one year. Correspondingly, those with low remnant cholesterol but high apoB and high LDL cholesterol had a HR of 1.20 (1.11-1.30) for ASCVD and an OR of 5.1 (4.3-5.9) for starting lipid-lowering therapy. In a primary prevention setting, elevated apoB due to high remnant cholesterol confers high risk of ASCVD but less initiation of lipid-lowering therapy compared to elevated apoB due to high LDL cholesterol, representing a guideline-based limitation and an unmet medical need.

Chronic hyperglycemia inflicts serious cellular damage by inducing oxidative stress through the excessive production of free radicals. This oxidative milieu may impair the cellular redox capacity and disrupt the insulin-like growth factor (IGF) system, thereby increasing the risk of cardiovascular complications. This study aimed to investigate plasma levels of components of the IGF system and antioxidant biomarkers in young adults with type 1 diabetes mellitus (T1DM) compared to age-matched healthy controls in Brazil. This study included 129 patients with T1DM (76 female, 53 male; mean age 26.97 ± 0.6 years) and 95 healthy controls (61 female, 34 male; mean age 27.35 ± 0.68 years). Young Brazilian adults with T1DM had significantly lower mean IGF-I and higher mean IGFBP-1 levels compared to healthy controls. The T1DM group showed a more atherogenic profile, characterized by a significantly elevated ApoB/ApoA1 ratio and increased oxidized LDL levels. However, a subset of patients with significantly better glycemic control exhibited serum IGF-I and IGFBP-1 levels within the normal range observed in controls, which may indicate the presence of residual functional beta-cell activity or reflect better glycemic control in this subgroup. Antioxidant components and oxidative stress biomarkers were significantly upregulated in the T1DM group compared to the control group, suggesting a compensatory adaptive response. No significant correlation was observed between biomarkers of oxidative stress and the IGF-system. Show less

Lipid overaccumulation in the liver predisposes ducks to metabolic disorders. The molecular mechanism of oleic acid (OA)-induced hepatic steatosis in ducks is not fully elucidated. A cellular model of steatosis was established by treating primary duck hepatocytes with OA. Transcriptome sequencing was performed to identify key signaling pathways and candidate genes. The role of Apolipoprotein A1 (APOA1) was investigated through overexpression and knockdown experiments. Intracellular triglycerides (TGs) were quantified commercially; lipid droplets were visualized by Oil Red O staining. Intracellular TG accumulation was induced by OA treatment in a dose-dependent manner. Through transcriptome analysis, 1045 differentially expressed genes (DEGs) were identified, with APOA1 being recognized as a key candidate within the peroxisome proliferator-activated receptor (PPAR) signaling pathway. The content of TGs and lipid droplets was increased by APOA1 overexpression, whereas these effects were suppressed by APOA1 knockdown. The expression of acetyl-CoA carboxylase alpha (ACACA) and fatty acid synthase (FASN) was upregulated by APOA1. Conversely, the expression of carnitine O-palmitoyltransferase 1 (CPT1), acyl-CoA oxidase 1 (ACOX1), and apolipoprotein B (APOB) was downregulated. This study demonstrates that OA upregulates APOA1, suggesting the involvement of the PPAR pathway and providing a theoretical basis for modulating hepatic fat deposition. Show less

Gingival crevicular fluid (GCF) reflects both local periodontal inflammation and systemic conditions. This review highlights the role of oxidative stress, oxidised low-density lipoprotein (oxLDL), and apolipoprotein B (apoB) as molecular links between periodontitis and metabolic disorders. Elevated GCF levels of oxLDL and apoB indicate enhanced vascular permeability and local oxidative modification, particularly in diabetes. Furthermore, oxLDL promotes the formation of neutrophil extracellular trap (NET) via connecting oxidative stress with immune-mediated tissue injury. These insights establish GCF as a valuable, non-invasive biomarker for understanding the interplay between periodontal and systemic diseases. Show less

Rotator cuff tear is the most common tendon injury. Currently, arthroscopic rotator cuff repair (ARCR) is the primary method for diagnosing and treating rotator cuff tear. One of the major complications following ARCR is retear. This study aims to evaluate the correlation between systemic lipid metabolism and retear occurrence after ARCR through a retrospective analysis of postoperative patients. This retrospective study reviewed consecutive patients of a single surgeon who underwent ARCR from January 2021 to January 2022. Eligibility for inclusion required complete sequential follow-up data, encompassing preoperative laboratory tests and a series of postoperative magnetic resonance imaging (MRI) evaluations at 1, 2, 3, and 6 months. Exclusion criteria included patients with incomplete laboratory tests, a history of tumors, prior shoulder surgeries, isolated subscapularis tendon tears, the rotator cuff related muscles are not clearly or completely displayed in MRI, absence of follow-up MRI, or those under treatment with lipid-lowering medications. Logistic regression analysis was employed to identify preoperative factors associated with retear, with statistical significance adjudged at P < .05. From the initial cohort of 400 patients who underwent ARCR during the study period, 202 met both inclusion and exclusion criteria. These patients were subsequently divided into a training group (n = 122) and a test group (n = 80), maintaining a ratio of 6:4. Statistical analysis revealed significant risk factors for post-ARCR retear including high body mass index (>27.1; odds ratio (OR): 5.994, 95% confidential interval (CI): 1.762-13.980; P = .042), subscapularis muscle fatty infiltration of Grades 3 and 4 (OR: 8.509, 95%CI: 3.811-17.702; P = .009), serum apolipoprotein B (ApoB) levels exceeding 1.4 g/L (OR: 9.658, 95%CI: 3.520-21.753; P = .028), and an ApoB/A1 ratio greater than 1.8 (OR: 5.098, 95%CI: 1.787-10.496; P = .016). Conversely, the serum high-density lipoprotein level above 1.2 mmol/L (OR: -3.342, 95%CI: -7.466 to 0.659; P = .039) served as a protective factor. The model incorporating these 5 factors predicted retear with a sensitivity of 78.3% and specificity of 98.0% (area under the curve = 0.924, accuracy = 90.3%). Moreover, a new model comprising 3 lipid metabolism-related factors including high-density lipoprotein, ApoB and the ApoB/A1 ratio showed a sensitivity of 80.5% and specificity of 83.2% (area under the curve = 0.866, accuracy = 85.8%) for predicting retear after ARCR. A predictive model utilizing key systemic lipid metabolism markers including HDL, ApoB, and the ApoB/A1 ratio, demonstrates effective forecasting of retear incidence following ARCR. Show less

However, it detects calcified plaques and may miss non-calcified or soft plaques. This study compared the diagnostic accuracy of CAC scoring with coronary computed tomography angiography (CCTA) for detecting CAD in asymptomatic individuals with risk factors. Eighteen asymptomatic adults with a CAC score of 0 underwent CCTA to evaluate for subclinical CAD. Clinical, biochemical, and lifestyle risk factors were assessed. Diagnostic agreement between CAC and CCTA was analyzed using the Wilcoxon signed rank test. The cohort had a mean age of 51.4 ± 10.6 years, 88.8% were male, and mean body mass index (BMI) was 27.7 ± 3.6 kg/m CCTA detected non-calcified atherosclerosis missed by CAC and demonstrated superior sensitivity for early CAD detection in asymptomatic individuals.

Chronic heart failure (CHF) is frequently complicated by depression, which worsens prognosis but remains underdiagnosed due to symptom overlap and a lack of objective screening tools. Although biomarkers reflecting lipid metabolism, insulin resistance, inflammation, and neuro-immuno-endocrine imbalance have been implicated in both CHF and depression, their predictive value for psychiatric outcomes in CHF patients is unclear. This study aimed to develop and validate interpretable machine learning (ML) models for predicting depression risk in CHF patients via the use of clinical and biomarker data. We retrospectively enrolled 3, 110 CHF patients admitted between January 2015 and December 2024 at Guang'anmen Hospital. Demographic, clinical, and laboratory indicators, including apolipoprotein B (ApoB), the triglyceride-glucose (TyG) index, and a novel glycated TyG (gTyG) index, were collected. Logistic regression and restricted cubic spline analyses were used to assess dose-response associations between biomarkers and depression. Eight ML algorithms were trained and evaluated, with model interpretability assessed via SHapley Additive exPlanation (SHAP). Among the 3, 110 patients, 37.3% had comorbid depression. Elevated ApoB and gTyG indices were strongly associated with depression risk in both the unadjusted and fully adjusted models (ApoB Q4 vs. Q1: OR 5.41, 95% CI 3.72-7.87; gTyG Q4 vs. Q1: OR 2.88, 95% CI 1.88-4.41; both P < 0.001), demonstrating clear nonlinear dose-response relationships. The TyG index was associated with depression in the crude analyses but lost significance after adjustment. Among the ML models, the RF model achieved the best performance (AUC 0.933 in training, accuracy 0.814, sensitivity 0.939). SHAP analysis revealed that the ApoB and gTyG indices were the most influential predictors. A user-friendly web application was developed for individualized risk prediction. This study demonstrated that the ApoB and gTyG index are robust biomarkers for predicting depression risk in CHF patients. The RF model provided the highest predictive accuracy and interpretability, highlighting its potential utility for early risk stratification and targeted intervention. The incorporation of these biomarkers into routine clinical practice may facilitate timely identification and management of depression in CHF patients, ultimately improving patient outcomes.

In recent years, special attention has been paid to the role of endotoxemia in the pathogenesis of chronic inflammatory processes and vascular complications of type 1 diabetes mellitus (DM1) - increased levels of circulating bacterial lipopolysaccharide (LPS). Endotoxemia occurs due to increased permeability of the intestinal barrier ("leaky gut syndrome") and/or decreased activity of its elimination systems. Correction of endotoxemia is a promising direction in the complex therapy of DM1. Traditional approaches include strict glycemic control and the use of certain pharmacological agents, however, the search for effective non-pharmacological methods, such as the use of natural mineral waters, remains relevant. Despite the theoretical background, data on the effect of a course of mineral water intake on markers of endotoxemia and systemic inflammation in patients with DM1 are extremely limited. to evaluate the effect of mineral waters on the state of LPS-binding systems, the level of circulating lipopolysaccharide and markers of inflammation in patients with type 1 diabetes mellitus. The study included 53 patients with a verified diagnosis of type 1 diabetes mellitus. The intervention group ( In patients of group 1, after the use of mineral waters, a significant decrease in circulating LPS ( The study demonstrates that a 30-day course of taking "Krymskaya" mineral water in addition to standard insulin therapy in patients with type 1 diabetes mellitus leads to a statistically significant decrease in the level of circulating lipopolysaccharide (LPS), a key trigger of endotoxemia and chronic inflammation. The results obtained justify the expediency of further studying the use of mineral waters, in particular bicarbonate-chloride-sodium, as a component of complex non-pharmacological therapy aimed at correcting endotoxemia and improving the metabolic profile in patients with type 1 diabetes mellitus.

Heterozygous familial hypercholesterolemia (HeFH) is the most prevalent inherited dyslipidemia, and it predisposes individuals to premature atherosclerotic cardiovascular disease. Genetic testing can provide a definitive diagnosis. The spectrum of causal DNA variants in Ontario patients with hypercholesterolemia is not fully defined. In Southwestern Ontario patients with a clinical diagnosis of HeFH, we performed targeted next-generation DNA sequencing and bioinformatic analysis to determine the qualitative and quantitative spectrum of pathogenic and likely pathogenic (P/LP) variants. We observed 101 unique P/LP variants in 254 patients, of which 6 were novel This study provides a comprehensive overview of the clinical and genetic spectrum of HeFH in Southwestern Ontario. The P/LP variant diversity reflects historical colonization and later migration patterns both from across the world and interprovincially from Quebec. Show less

To explore the correlation between different traditional Chinese medicine (TCM) constitution types and apolipoprotein B (ApoB) in patients with hyperuricemia (HUA) and to investigate the relationships between TCM constitutions, uric acid levels, and various cardiovascular risk factors. A cross-sectional study involving 683 patients diagnosed with HUA was conducted. Patients' TCM constitutions were classified using the standardise "Classification and Determination of TCM Constitution" questionnaire. Serum uric acid (UA), lipid profiles, ApoB, and homocysteine (Hcy) levels were measured. Among 683 HUA patients, phlegm-dampness (22.99% ) and damp-heat constitution (20.06% ) were the most common TCM constitution types. UA, ApoB, and Hcy levels in patients with phlegm-damp constitution were significantly higher than those in other constitutions (P< 0.05). UA levels were negatively correlated with HDL-C (r=-0.472, P= 0.027) and positively correlated with ApoB (r= 0.618, P= 0.012) and Hcy (r= 0.492, P= 0.018). Phlegm-damp and damp-heat constitutions are the most common TCM constitution types in HUA patients and are associated with higher levels of UA, ApoB, and Hcy. These constitutional types are independently associated with increased cardiovascular risk. Show less

Recently, we reported that a pemafibrate extended-release (XR) formulation lowered low-density lipoprotein cholesterol (LDL-C) and cholesterol synthesis and absorption markers in a phase 2 clinical pharmacology study. Here we describe our post-hoc analysis of that study, discuss the mechanism by which pemafibrate lowers LDL-C, and suggest which patients may respond favorably to pemafibrate treatment. In the phase 2 study, patients with hypertriglyceridemia received treatment with pemafibrate immediate-release (IR) 0.2 mg/day or XR 0.4 mg/day or 0.8 mg/day. This post-hoc subgroup analysis examined the percentage change in LDL-C, apolipoprotein B (ApoB), non-HDL-C, and cholesterol synthesis and absorption markers, in subgroups by baseline LDL-C, and then determined the correlation between the percentage change in LDL-C and the percentage change in cholesterol synthesis and absorption markers. Our analysis included 60 patients who received two of three formulations of the drug. A total of 78.3% (47/60) were male, 16.7% (10/60) had type 2 diabetes mellitus, and 10% (6/60) received concomitant statins. The percentage of LDL-C lowering was greater in the population with high baseline LDL-C, and similar trends were noted for the ApoB, non-HDL-C, and cholesterol synthesis and absorption markers. The percentage change in LDL-C was positively correlated with the percentage change in lathosterol, β-sitosterol, and campesterol. In patients with hypertriglyceridemia, results suggested that pemafibrate lowered LDL-C by inhibiting cholesterol synthesis in the liver and cholesterol absorption from the intestinal tract. This lowering effect was greater in populations with higher baseline LDL-C. Show less
