Colchicine effect on biomarkers of cardiac remodelling and atherosclerosis in ST-elevation myocardial infarction: A randomized controlled trial.

AIMS: Owing to its underlying inflammatory nature, atherosclerotic cardiovascular disease remains the leading global cause of mortality, particularly post-ST-elevation myocardial infarction (STEMI), a condition with significant risk for further cardiovascular events and mortality. This study aimed to investigate colchicine's effect on inflammation, cardiac remodelling and atherosclerotic risk in STEMI patients. METHODS: We conducted a randomized controlled study on 88 STEMI patients undergoing percutaneous coronary intervention. Eligible patients were randomly assigned to 1 of 2 groups. The control group received the guideline-directed medical therapy for STEMI, and the test group received guideline-directed medical therapy and 0.5 mg colchicine twice daily for 3 months. The soluble suppressor of tumorigenicity (sST2), interleukin-1ß, lipid profile parameters, triglyceride (TG)/high-density lipoprotein (HDL-C) ratio levels and left ventricular ejection fraction were evaluated for patients at baseline and the end of the 3 months. RESULTS: No significant effects were reported for colchicine on sST2, interleukin-1ß levels or left ventricular ejection fraction. Colchicine significantly lowered TG levels vs. controls, 134 (46-353) vs. 176 (72-825) respectively, P = .02, as well as TG/HDL-C ratio levels, 4.16 (2.75-5.24) vs. 5.11 (3.51-8.33),` respectively, P = .024. sST2 levels of the studied cohort were positively correlated with their TG/HDL-C ratio levels (R = .459, P < .001) at the end of follow-up. CONCLUSION: Our study highlights a promising impact of colchicine on atherosclerosis and cardiac remodelling factors in STEMI patients. Colchicine significantly reduced TG levels and TG/HDL-C ratio and was safe and well tolerated. Larger long-term studies powered to assess clinical outcomes of remodelling are necessary to confirm its beneficial effects in STEMI. GOV REGISTRATION ID: NCT06054100.

Impact of metabolic syndrome components on clinical outcomes in hypertriglyceridemia-induced acute pancreatitis.

BACKGROUND: The incidence of hypertriglyceridemia (HTG)-induced acute pancreatitis (AP) is steadily increasing in China, becoming the second leading cause of AP. Clinical complications and outcomes associated with HTG-AP are generally more severe than those seen in AP caused by other etiologies. HTG-AP is closely linked to metabolic dysfunction and frequently coexists with metabolic syndrome or its components. However, the impact of metabolic syndrome components on HTG-AP clinical outcomes remains unclear. AIM: To investigate the impact of metabolic syndrome component burden on clinical outcomes in HTG-AP. METHODS: In this retrospective study of 255 patients diagnosed with HTG-AP at the First Affiliated Hospital of Guangxi Medical University, we collected data on patient demographics, clinical scores, complications, and clinical outcomes. Subsequently, we analyzed the influence of the presence and number of individual metabolic syndrome components, including obesity, hyperglycemia, hypertension, and low high-density lipoprotein cholesterol (HDL-C), on the aforementioned parameters in HTG-AP patients. RESULTS: This study found that metabolic syndrome components were associated with an increased risk of various complications in HTG-AP, with low HDL-C being the most significant risk factor for clinical outcomes. The risk of complications increased with the number of metabolic syndrome components. Adjusted for age and sex, patients with high-component metabolic syndrome had significantly higher risks of renal failure [odds ratio (OR) = 3.02, 95%CI: 1.12-8.11)], SAP (OR = 5.05, 95%CI: 2.04-12.49), and intensive care unit admission (OR = 6.41, 95%CI: 2.42-16.97) compared to those without metabolic syndrome. CONCLUSION: The coexistence of multiple metabolic syndrome components can synergistically worsen the clinical course of HTG-AP, making it crucial to monitor these components for effective disease management.

Gestational diabetes complicated with preterm birth: a retrospective cohort study.

OBJECTIVE: To delineate the clinical characteristics of preterm birth (PTB) in the context of gestational diabetes mellitus (GDM). METHODS: A retrospective cohort study was conducted, including 14,314 pregnant women with GDM who delivered at Fujian Provincial Maternity and Children's Hospital from January 1, 2018, to December 31, 2021. PTB was stratified into late PTB (34-36 weeks of gestation) and early PTB (< 34 weeks) and pregnancy complications were analyzed. RESULTS: Compared to the term birth (TB) cohort, a higher prevalence of premature rupture of membranes, hypertensive diseases of pregnancy (HDP), intrahepatic cholestasis of pregnancy (ICP), anemia and cervical insufficiency was observed in the PTB cohort. Notably, early PTB increased the incidence of HDP, ICP, anemia and cervical insufficiency compared to late PTB. In the early stages of pregnancy, early PTB was characterized by elevated triglyceride (TG) levels and decreased high-density lipoprotein cholesterol (HDL-C) levels compared to late PTB. In the late pregnancy stages, early PTB was associated with increased white blood cell (WBC) and neutrophil counts. No disparities were observed in 75 g oral glucose tolerance test (OGTT) between early and late PTB. CONCLUSION: Enhanced surveillance and management of GDM, particularly in the presence of HDP, ICP and anemia, are imperative to mitigate the risk of PTB. The lipid profile may serve as a predictive tool for early PTB in the early stages of pregnancy, warranting further studies.

Lymphocyte to high density lipoprotein ratio can predict the short-term prognosis of hepatitis B virus-related acute-on-chronic liver failure patients.

Background: Acute-on-chronic liver failure (ACLF) is a syndrome characterized by systemic inflammation, leading to high short-term mortality. The lymphocyte to high-density lipoprotein ratio (LHR) has been introduced as a novel marker of inflammation. However, its role as a prognostic inflammatory biomarker in the context of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) has received limited attention. Methods: We retrospectively included 272 patients with HBV-ACLF who met the definition of APALC. Data on clinical features and laboratory tests were collected from medical records within 24 h. Logistic regression was used to identify risk factors for poor short-term prognosis, and LHR-based prediction (LHRB) models were constructed based on risk factors. Furthermore, the accuracy of the LHRB model was validated through rigorous testing. Results: In the survival and death groups, there were statistical differences in their CTP, MELD, MELD-Na, COSSH-ACLF II scores, and LHR. Multivariate logistic regression identified seven predictors significantly associated with 28-day mortality. Furthermore, statistically significant differences in short-term mortality and certain clinical laboratory tests for poor prognosis were observed between the high and low LHR groups. To assess the predictive performance of various models in terms of short-term mortality, the area under the receiver operating characteristic curve (AUROC) was calculated. The AUROC values for the CTP, MELD, MELD-Na, COSSH-ACLF II, and LHRB models were found to be 0.725, 0.788, 0.772, 0.871, and 0.877, respectively. The results in the validation group were similar to those in the training group, and the validation results suggested excellent performance of the LHRB model. Conclusion: LHR levels have the potential to serve as indicators for the prognosis of HBV-ACLF. Additionally, the recently developed LHRB model offers an accessible risk assessment tool.

The non-HDL-C to APOB ratio as a predictor of inaccurate LDL-C measurement in patients with chronic intrahepatic cholestasis and jaundice: a retrospective study.

Background: Cholestasis is characterized by the accumulation of bile in the liver or biliary system due to obstruction or impaired flow, necessitating lipid profiling to assess lipid metabolism abnormalities. Intrahepatic cholestasis, being the most significant type of cholestasis, further complicates the assessment of lipid abnormalities. However, the accuracy of low-density lipoprotein cholesterol (LDL-C) measurement in intrahepatic cholestasis patients remains uncertain. Objective: This study aimed to evaluate the consistency of the homogeneous assay and the Friedewald formula in detecting LDL-C levels and identify factors influencing LDL-C test results in intrahepatic patients with cholestasis. Methods: Retrospective analysis of laboratory data was conducted on intrahepatic cholestatic patients. Correlations between LDL-C values obtained using the homogeneous method (LDL-C(D)) and the Friedewald formula (LDL-C(F)), as well as associations between high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (ApoA1), LDL-C(D) and LDL-C(F), and apolipoprotein B (ApoB), were analyzed. Logistic regression analyses were employed to identify diagnostic indicators for inaccurate LDL-C measurements in intrahepatic cholestatic patients. Results: Compared to patients with intrahepatic cholestasis without jaundice, the correlation between LDL-C(F) and LDL-C(D) was weaker in those with jaundice. Additionally, HDL-C exhibited a strong correlation with ApoA1 in both jaundice and non-jaundice cholestasis cases. Elevated non-HDL-C to APOB ratio (NH-C/B Ratio) levels (>4.5) were identified as a reliable predictor of inaccurate LDL-C measurements in patients with chronic intrahepatic cholestasis accompanied by jaundice. Conclusions: LDL-C measurement reliability is moderately weaker in patients with intrahepatic cholestasis accompanied by jaundice. Elevated levels of the NH-C/B ratio serve as a significant predictor of inaccurate LDL-C measurements in this chronic patient population, highlighting its clinical relevance for diagnostic assessments.

Potentially Risk Factors for New Atrial Fibrillation in Patients Undergoing Coronary Artery Bypass Grafting: A Retrospective Cohort Study.

Objective: Our study evaluated the risk factors for new postoperative atrial fibrillation (POAF) by analyzing the data collected from patients who underwent first coronary artery bypass grafting (CABG). Methods: Our study retrospectively collected data from January 2021 to December 2023 at Changzhi People's Hospital. The perioperative period data were collected, and logistic regression was used to analyze the independent predictors of the occurrence of POAF after CABG and the related predictive values of risk factors were analyzed by using the subjects' work characteristic curve (ROC). Results: A total of 169 patients were included, and there are 45 patients in the POAF group, with an incidence of 26.6%, and 124 in the non-POAF group. The POAF group was significantly higher than the non-POAF group in terms of age (69.2±8.8 years vs 62.3±9.3 years) and preoperative LAD (42.7±7.2mm vs 36.8±5.5mm), and the difference was significant (P<0.05). Preoperative HDL-C in the POAF group were lower than non-POAF group (1.0±0.5 mmol/l vs 1.4±0.7 mmol/l, P<0.05). The logistic regression analysis revealed a significant correlation between age, LAD, HDL-C and the occurrence of POAF (P<0.05). According to the ROC curve analysis, age >64.5 years, LAD >41mm, and HDL-C <0.9 mmol/l were the cut-off values for predicting the occurrence of POAF (AUC1=0.733; AUC2=0.741; AUC3=0.647, P < 0.05). The combined age + LAD + HDL-C (AUC = 0.755; P < 0.05) had a higher diagnostic value and high sensitivity. Conclusion: The age, LAD, and HDL-C are independent risk factors for the POAF after CABG, and clinicians should assess these risk factors as much as possible when managing patients in the perioperative period and make corresponding measures to prevent the development of POAF.

Prognostic value of the monocyte-to-high-density lipoprotein-cholesterol ratio in ACS patients: A systematic review and meta-analysis.

BACKGROUND: Globally, diseases of the cardiovascular system stand as the principal contributors to mortality and are anticipated to show an upward trajectory. The occurrence of Acute Coronary Syndrome (ACS) has been linked to underlying inflammatory processes. The monocyte-to-high-density lipoprotein-cholesterol (MHR) ratio has garnered significant attention as a prognostic biomarker, encapsulating the synergistic roles of inflammation and lipid metabolism in the pathophysiology of cardiovascular diseases, including ACS. AIMS: This meta-analysis examines the prognostic MHR ratio in ACS patients. METHODS: We systematically searched PubMed, Embase, Scopus, Web of Science, and the Cochrane Library databases to identify the relevant meta-analyses up to February 26, 2024. The findings were aggregated into risk ratios with 95% confidence intervals. RESULTS: Eleven studies, with 7421 patients, were included. Low MHR levels compared to high MHR levels were associated with statistically significantly lower in-hospital mortality (0.9% vs. 5.5%; respectively; p<0.001), 3-month mortality (4.4% vs. 11.2%; p = 0.02), 6-month follow-up mortality (4.0% vs. 10.2%; p = 0.03), 1-year mortality (4.2%, vs. 10.2%; p<0.001), as well as long-term follow-up mortality (7.5% vs. 13.7%; p<0.001). CONCLUSIONS: MHR has both good predictive properties for mortality and MACE (short- and long-term). Data indicate that MHR may improve in-hospital and long-term cardiovascular risk prediction. It may, therefore, be an effective tool for risk re-estimation and the selection of patients for whom intensive lipid-lowering treatment may be particularly useful.

High-density lipoprotein functionality in cholesterol efflux in early childhood is related to the content ratio of triglyceride to cholesterol.

Cholesterol efflux capacity (CEC), commonly measured as a useful risk marker of atherosclerotic cardiovascular disease, depends on high-density lipoprotein (HDL) functionality and its concentration. We defined the relative HDL functionality in cholesterol efflux, not influenced by HDL concentration, as the ratio of measured CEC to standardized CEC (stCEC) based on HDL-cholesterol (HDL-C) of each individual using the curve regression equation obtained from the correlation. HDL-C, CEC, and CEC/stCEC levels in the < 28-day-old participants (neonates) were significantly low compared to those of the ≥ 28-day-old participants, indicating that the low CEC levels in the neonates depend on not only lower HDL-C but also lower HDL functionality. The low level of CEC/stCEC was remarkable in neonates born at < 34 weeks of gestation and did not improved to the reference level (1.000) until the infantile period. The relatively low or high CEC/stCEC ratios in neonates and infants were associated with lower or higher HDL-TG and HDL-TG/HDL-C ratio, respectively. However, no apparent effect of HDL-TG and HDL-TG/HDL-C ratio on CEC/stCEC was observed in the ≥ 1-year-old participants, indicating that HDL functionality in cholesterol efflux could be associated with the various HDL particles with various lipid compositions, but not just with HDL-TG and HDL-TG/HDL-C ratio.

The potential of platelet to high-density lipoprotein cholesterol ratio (PHR) as a novel biomarker for heart failure.

Heart failure (HF) is closely linked to platelet counts and lipid levels. The platelet-to-high-density lipoprotein cholesterol ratio (PHR) is a novel marker for assessing cardiovascular disease. This study investigates the relationship between PHR and HF. We analyzed data from ten consecutive NHANES survey cycles (1998-2018), focusing on self-reported HF diagnoses with complete PHR information. PHR was calculated as platelet count divided by HDL-C (mmol/L). A multivariate logistic regression model was used to examine the association between PHR and HF, with subgroup analyses to identify potential influencing factors. RCS curve plotting and threshold effect analysis were employed to describe non-linear relationships. The study included 31,410 adults aged 20-85 years. The multivariate logistic regression indicated that individuals with the highest PHR had 82% increased likelihood of HF compared to those with the lowest PHR (OR = 1.82; 95% CI, 1.37-2.40, P < 0.001). Subgroup analyses revealed no significant interactions between PHR and specific subgroups (P > 0.05), except in those with alcohol consumption (yes/no) and BMI subgroups (P < 0.05). The association between PHR and HF was non-linear, with a notable turning point at 281.53. Elevated PHR is significantly associated with HF, suggesting it may serve as an effective clinical indicator for monitoring HF risk. Larger prospective cohort studies are needed to validate these findings and further assess the clinical utility of PHR in cardiovascular risk assessment.

Cabozantinib-encapsulated and maytansine-conjugated high-density lipoprotein for immunotherapy in colorectal cancer.

Advanced colorectal cancer (CRC) responds poorly to current adjuvant therapies, partially due to its immunosuppressive intestinal microenvironment. We found that myeloid-derived suppressor cells (MDSCs) were enriched in orthotopic tumors due to treatment-induced succinate release, which activated tuft cells and upregulated interleukin 25 (IL-25) and interleukin 13 (IL-13). We engineered a cabozantinib (Cabo)-encapsulated and maytansine (DM1)-conjugated synthetic high-density lipoprotein (ECCD-sHDL) to modulate the tumor microenvironment. DM1 induced immunogenic cell death and promoted the maturation of dendritic cells. Meanwhile, Cabo alleviated DM1-induced succinate release, preventing tuft cell activation, downregulating IL-25 and IL-13 secretion, and reducing intratumoral MDSC infiltration. ECCD-sHDL increased the densities of active cytotoxic T lymphocytes (CTLs) and M1 macrophages in the tumors, effectively inhibiting tumor growth and metastasis, thereby prolonging survival in murine CRC models. Our study sheds light on the mechanism of treatment-induced immunosuppression in orthotopic CRC and demonstrates that this combinatorial therapy could be an effective treatment for CRC.

Relation between peripheral blood inflammatory indices and severity of central retinal artery occlusion.

Background: Central retinal artery occlusion (CRAO) has been identified as an acute emergency resulting in vision loss, with its pathogenesis potentially involving systemic inflammation and abnormal lipid metabolism. Over recent years, it has been established that peripheral blood inflammatory indices, including the neutrophil-to-lymphocyte ratio (NLR), the systemic immunoinflammatory index (SII), and the monocyte-to-high-density lipoprotein ratio (MHR), play significant roles in assessing systemic inflammation and lipid metabolism. However, the role of these indices in assessing the severity of CRAO has rarely been explored. This study aimd to investigate the relationship between these inflammatory indices and the severity of CRAO. Methods: This was a retrospective clinical study with a total of 49 CRAO patients and 50 age- and sex-matched controls involved. The patients with CRAO were divided into three groups (13 with incomplete CRAO, 16 with subtotal CRAO and 20 with total CRAO). Data were compared across these groups, and additionally, correlation analysis, restricted cubic spline plots, and receiver operating characteristic curve analysis were performed. Results: The values of NLR, SII and MHR were significantly higher in the CRAO group compared to controls (NLR: 2.49(1.71,3.44) vs 1.60(1.24,1.97), P<0.001; SII: 606.46(410.25,864.35) vs 403.91(332.90,524.31), P=0.001; MHR: 0.33(0.26,0.44) vs 0.25(0.21,0.34), P<0.001). MHR was also significantly higher in total CRAO than in incomplete CRAO and subtotal CRAO (0.41(0.32,0.60) vs 0.29(0.21,0.43), P=0.036; 0.41(0.32,0.60) vs 0.29(0.23,0.38), P=0.017). Significant positive associations were found between MHR, NLR, SII and both the incidence (all P<0.001) and severity (P<0.001, P<0.001, P=0.003, respectively) of CRAO. MHR had a linear relationship with both the occurrence and severity of CRAO (P-overall=0.013, P-non-linear=0.427 and P-overall=0.013, P-non-linear=0.825). Combining MHR and NLR significantly improved diagnostic efficacy for CRAO and total CRAO, with area under the curve of 0.816 and 0.827, respectively, compared to using MHR alone (0.705 and 0.816). Conclusion: Elevated levels of peripheral blood NLR, SII, and MHR are positively associated with CRAO incidence, highlighting their potential as early predictive markers. The combined NLR and MHR index further enhances diagnostic accuracy and may facilitate timely assessment of CRAO severity by ophthalmologists and internists.

Prevalence and clinical correlates of impaired fasting blood glucose in children and adolescents with depressive disorder and relationship with triglyceride and high-density lipoprotein ratio.

Depressive disorder is a significant public health problem worldwide, which adversely affects children and adolescents' health. Impaired fasting blood glucose (IFG) is more common in depressive disorder, which becomes a clinical problem that needs to be focused on. The study purposed to determine the prevalence and related factors of IFG in Chinese children and adolescents with depressive disorder and the relationship between triglyceride and high-density lipoprotein cholesterol (TG/HDL-C) ratio and IFG. This research encompassed 756 individuals aged 8 to 18 with major depressive disorders, all diagnosed under DSM-5 criteria at the Third People's Hospital of Fuyang from January 2020 to December 2021. We detected fasting blood glucose (FBG) and lipid levels and assessed the suicidal behaviors and depressive symptoms severity of each participant. The sociodemographic and included study variables were collected and analyzed. Our study employed multiple logistic regression to discern independent factors affecting IFG in conjunction with depressive disorders among children and adolescents. The prevalence of IFG was 6.5% (49/756). IFG was positively correlated with FBG, BMI, TG, TG/HDL-C, and was negatively correlated with gender and the type of antidepressant drug taken. Binary logistic analysis showed that male (OR = 2.57, 95% CI: 1.43-4.63, P = 0.002) and higher levels of TG (OR = 1.63, 95% CI: 1.11-2.38, P = 0.013) were independently associated with IFG in children and adolescents with depressive disorder. The incidence of IFG in children and adolescents with depressive disorder was high and was positively related to the TG/HDL-C ratio. The evaluation and management of IFG in pediatric depression should extend beyond pharmacological interventions. Comprehensive strategies in both assessment and management of IFG are essential to address this condition effectively in young patients facing depressive disorders.

Exploring the impact of HDL and LMNA gene expression on immunotherapy outcomes in NSCLC: a comprehensive analysis using clinical & gene data.

Objectives: Analyzing the impact of peripheral lipid levels on the efficacy of immune checkpoint inhibitor therapy in non-small cell lung cancer (NSCLC) patient populations and exploring whether it can serve as a biomarker for broadening precise selection of individuals benefiting from immunotherapy. Methods: We retrospectively collected clinical data from 201 cases of NSCLC patients receiving immune checkpoint inhibitor therapy. The clinical information included biochemical indicators like total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). We utilized machine learning algorithms and Cox proportional hazards regression models to investigate independent predictors for both short-term and long-term efficacy of immunotherapy. Additionally, we concurrently developed a survival prediction model. Analyzing the Genes of Patients with Treatment Differences to Uncover Mechanisms. Results: Correlation analysis revealed a significant positive association between HDL and ORR, DCR, and PFS. T-test results indicated that the high-HDL group exhibited higher DCR (81.97% vs. 45.57%) and ORR (61.48% vs. 16.46%). Kruskal-Wallis test showed that the high-HDL group had a longer median PFS (11 months vs. 6 months). Utilizing six machine learning algorithms, we constructed models to predict disease relief and stability. The model built using the random forest algorithm demonstrated superior performance, with AUC values of 0.858 and 0.802. Furthermore, both univariate and multivariate Cox analyses identified HDL and LDL as independent risk factors for predicting PFS. In patients with poor immunotherapy response, there is upregulation of BCL2L11, AKT1, and LMNA expression. Conclusion: HDL and LDL are independent factors influencing the survival prognosis of NSCLC patients undergoing immune checkpoint inhibitor therapy. HDL is expected to become new biomarkers for predicting the immunotherapy efficacy in patients with NSCLC. In patients with poor immunotherapy response, upregulation of the LMNA gene leads to apoptosis resistance and abnormal lipid metabolism.

Correlation of Serum Vitamin D and High-Density Lipoprotein (HDL) Cholesterol Levels With Disease Activity in Rheumatoid Arthritis: A Single-Center Experience From Eastern India.

Background Rheumatoid arthritis (RA) is a progressive, symmetric, and erosive polyarthritis with a variety of extraarticular manifestations such as mononeuritis multiplex, central nervous system vasculitis, Felty's syndrome, dyslipidemia, carditis, and interstitial lung disease. Vitamin D plays a role in both adaptive and innate immunity, and its deficiency leads to the development of many autoimmune disorders. Additionally, RA patients have a lipid paradox consisting particularly of dysfunctional and low levels of high-density lipoprotein (HDL) with reduced low-density lipoprotein lowering effect, which increases cardiovascular morbidity and potentiates widespread systemic inflammation. Both are modifiable risk factors. Although there are numerous studies on vitamin D and HDL cholesterol in disease progression in RA, there is sparse literature from India studying both these factors in combination. In this study, we tried to establish the correlation of serum vitamin D and HDL cholesterol levels, if any, with disease activity using the Disease Activity Score 28 Erythrocyte Sedimentation Rate (DAS28 ESR) score. Methods A descriptive cross-sectional study comprising 80 patients was conducted at a tertiary care center in Eastern India over 12 months. Newly diagnosed RA patients aged >17 years satisfying the diagnostic criteria were included. Serum vitamin D level and HDL cholesterol were measured. Then, the DAS28 ESR score was calculated, and a correlation was looked for between serum vitamin D and HDL cholesterol. Results Patients aged 35-43 years accounted for 32 (42.5%) of participants, of whom 58 (72.5%) were females. Almost half, 38 (47.5%), had vitamin D deficiency. The mean vitamin D level was 22.988 ± 10.01 ng/ml. The mean HDL cholesterol level was 42.3 ± 7.23 mg/dl. The mean DAS28-ESR score was 3.81 ± 1.19. A statistically significant inverse correlation was found between vitamin D levels and DAS28 ESR score (p -0.0003) and HDL (p -0.000349). Conclusions Vitamin D deficiency and low HDL cholesterol levels are more common in RA patients. These factors may contribute to increased disease activity. Both are treatable factors in addition to conventional therapies.

Risk of Colorectal Cancer among Patients with One or Multiple Metabolic Syndrome Components.

Background/Objectives: Dysfunctions of metabolic syndrome (MetS) have been identified as a significant risk factor for colorectal cancer (CRC). However, current colon cancer guidelines do not classify patients with MetS as high risk, thereby leaving these individuals vulnerable. Consequently, we explored the relationship between MetS, its individual components, and the development of CRC in a cohort of patients with MetS to assess the necessity for CRC screening in these individuals. Methods: This study included patients ages 18 and older that received a service from the Marshall-Health (MH) practice plan, Cabell-Huntington Hospital (CHH), MU/JCESOM's Edwards Comprehensive Cancer Center (ECCC), or the University of Kentucky HealthCare (UKHC) system between 2010 and 2018. We implemented log-binomial regression models to assess the individual and collective effects of MetS components after adjusting other CRC risk factors. Results: Given that CRC prevalence increases in the older population (aged 65 years and above), and that multiple components of MetS are observed within the same population, we analyzed the concurrent impact of all MetS components on CRC. Log-binomial regression models were implemented to assess the risk of CRC due to MetS components after adjusting other risk factors. Conclusions: We identified specific components that markedly increased CRC risk, suggesting that individuals with these components should be prioritized for early screening. These findings could significantly influence early CRC screening protocols, with the ultimate aim to reduce mortality associated with the disease.

Apolipoprotein A-I Mimetic Peptide Restores VEGF-induced Angiogenesis in Hypercholesterolemic Ischemic Heart by Reducing HDL Proinflammatory Properties.

VEGF-induced angiogenesis is impaired in hypercholesterolemia. Previous studies showed that an apolipoprotein A-I(ApoA-I) mimetic peptide, D-4F, is able to reduce HDL proinflammatory index in hypercholesterolemia. Whether D-4F promotes angiogenesis in hypercholesterolemia remains unclear. Low-density lipoprotein receptor null (LDLr-/-) mice and LDLr-/-/ApoA-I-/- mice were fed with high-fat diet with or without D-4F (1mg/kg·d). C57BL/6 mice fed with normal diet served as control. The myocardial infarction was induced by ligation coronary artery, and the VEGFA-AAV 9 was injected in heart. The plasma HDL proinflammatory index, cardiac function, infarct size, and angiogenesis related signaling pathways were examined. The HDL proinflammatory index increases in hypercholesterolemic mice. VEGFA stimulates angiogenesis and improves cardiac function in ischemic heart of C57BL/6 mice, but not in hypercholesterolemic mice. D-4F reduces HDL proinflammatory index. D-4F combined with VEGFA stimulates the expression of CD31 and eNOS, activates ERK1/2, reduces infarct size, and improves cardiac function in ischemic heart in hypercholesterolemic LDLr-/- mice but not in hypercholesterolemic LDLr-/-/ApoA-I-/- mice. D-4F restores the VEGF-induced angiogenesis by reducing HDL proinflammatory properties in hypercholesterolemic ischemic heart.

The High-Sensitivity C-Reactive Protein to High-Density Lipoprotein Cholesterol Ratio and the Risk of Contrast-Induced Acute Kidney Injury in Patients Undergoing Percutaneous Coronary Intervention.

Background: The high-sensitivity C-reactive protein to high-density lipoprotein cholesterol ratio (CHR) is a novel biomarker associated with coronary artery disease (CAD) risk. This study aimed to analyze the relationship between CHR and contrast-induced acute kidney injury (CI-AKI). Methods: This retrospective cross-sectional research included 10,917 individuals who underwent PCI. CI-AKI was diagnosed using the Kidney Disease: Improving Global Outcomes (KIDIGO) standard. Univariate and multivariable logistic regression analyses were conducted to examine the association between CHR and CI-AKI, followed by a receiver operating characteristic (ROC) curve of participants to assess the clinical diagnostic performance of CHR on CI-AKI. Results: A total of 1037 patients (9.50%) developed CI-AKI after PCI. The age of individuals averaged 64.1 ± 11.1 years old, with 2511 females (23.0%). A multivariate logistic regression study revealed that higher CHR levels were linked to higher CI-AKI incidence rates ([Q4 vs. Q1]: odds ratio (OR) = 1.89, 95% confidence interval (CI) [1.42 to 2.54], p < 0.001). A restricted cubic spline analysis revealed a linear association between CHR and CI-AKI. ROC analysis indicated that CHR was an excellent predictor of CI-AKI (area under ROC curve = 0.606, 95% CI [0.588 to 0.624]). Conclusions: A high CHR level is strongly associated with increased CI-AKI incidence, suggesting that CHR may be an independent risk factor for CI-AKI.

The Predictive Value of SII Combined with UHR for Contrast-Induced Acute Kidney Injury in Patients with Acute Myocardial Infarction After Percutaneous Coronary Intervention.

Background: Contrast-induced acute kidney injury (CI-AKI) refers to the acute renal dysfunction caused by the injection of contrast agents. CI-AKI is currently a common complication after percutaneous coronary intervention (PCI). Objective: To investigate the predictive value of the combined systemic inflammatory index (SII) and urate/high-density lipoprotein cholesterol ratio (UHR) for CI-AKI after PCI in patients with AMI. Methods: A total of 1222 patients with AMI who underwent PCI were randomly divided into a training group and a validation group in an 8:2 ratio. According to the definition of CI-AKI diagnostic criteria, the training group was divided into CI-AKI group and non-CI-AKI group. Collect patient's blood and biochemical data, then calculate SII and UHR. The risk factors for CI-AKI were identified using LASSO and multivariate logistic regression analyses. A predictive column was created by using R language.Evaluate the predictive value of SII, UHR and their combination for CI-AKI after PCI using the area under the ROC curve (AUC). Results: Diabetes, Cystatin C, Diuretics, UHR, and LnSII were independent risk factors for CI-AKI in AMI patients after PCI. The ROC curve showed that the AUC of UHR and SII combined for predicting CI-AKI in AMI patients after PCI was 0.761 (95% CI: 0.709-0.812), with a sensitivity of 65.20% and a specificity of 76.70%, which was better than the prediction by either factor alone. Conclusion: High SII and high UHR are risk factors for AMI, and their combination can improve the accuracy of predicting CI-AKI in AMI patients after PCI.The prognosis of CI-AKI in AMI patients is worse than in the general population.

Maternal Lipids in Pregnancy and Later Life Dyslipidemia: The POUCHmoms Longitudinal Cohort Study.

OBJECTIVE: Maternal lipid levels increase in normal pregnancies. Here, we examine whether pregnancies with the highest total cholesterol, low-density lipoprotein (LDL) or triglyceride levels or the lowest high-density lipoprotein (HDL) levels predict future dyslipidemia post-pregnancy. DESIGN: Longitudinal cohort study. SETTING: Five communities in Michigan, USA. SAMPLE: Pregnant women (n = 649) with blood lipid levels measured at mid-pregnancy in the Pregnancy Outcomes and Community Health (POUCH) Study and at the POUCHmoms Study follow-up, 7-15 years later. METHODS: Maternal mid-pregnancy lipid levels were defined as 'high' (upper quartile of triglycerides ≥ 216 mg/dL, LDL ≥ 145 mg/dL and total cholesterol ≥ 256 mg/dL) or 'low' (lower quartile, HDL < 58 mg/dL) using whole sample lipid distributions. At follow-up, dyslipidemia was classified by the clinical cutoffs of triglycerides and total cholesterol ≥ 200 mg/dL, LDL ≥ 130 mg/dL and HDL < 50 mg/dL. Weighted regression models estimated the risk of dyslipidemia at follow-up in relation to pregnancy lipid levels, adjusted for baseline confounders. MAIN OUTCOME MEASURE: Dyslipidemia later in life. RESULTS: Mid-pregnancy triglycerides, LDL, and total cholesterol levels at the upper quartile were associated with at least threefold increase in the risk of abnormal triglycerides, LDL and total cholesterol levels later in life. Women with low mid-pregnancy HDL levels had just over a twofold increased risk of abnormally low HDL levels at follow-up. These associations persisted following adjustment for covariates, i.e. demographics, lifestyle, and years of follow-up. CONCLUSIONS: Higher mid-pregnancy LDL, total cholesterol and triglycerides and lower levels of HDL may signal future dyslipidemia risk and the need for closer lipid monitoring to ensure timely interventions that can attenuate cardiovascular disease risk.

Association between high-density lipoprotein-related inflammation index and periodontitis: insights from NHANES 2009-2014.

BACKGROUND: Periodontitis, a persistent inflammatory condition, significantly impairs individuals' overall quality of life. Lymphocyte-to-high-density lipoprotein cholesterol ratio (LHR), monocyte-to-high-density lipoprotein cholesterol ratio (MHR), neutrophil-to-high-density lipoprotein cholesterol ratio (NHR), and platelet-to-high-density lipoprotein cholesterol ratio (PHR) are new convenient and economical biomarkers. However, whether the above high-density lipoprotein-related inflammatory biomarkers are associated with periodontitis has rarely been investigated. Therefore, the research endeavor focused on uncovering potential relationships. METHODS: The research encompassed a diverse and extensive sample, comprising 9,470 participants, selected from the National Health and Nutrition Examination Survey spanning the years 2009 to 2014. The association between high-density lipoprotein-related inflammatory biomarkers and periodontitis was explored utilizing a multivariable logistic regression model with weighted analysis. Additionally, the study employed smoothed curve fitting to explore potential nonlinear relationships. Further stratified analyses and interaction tests were performed. RESULTS: This study indicated no apparent association between MHR and PHR with periodontitis, whereas LHR and NHR demonstrated a statistically significant positive relationship with the prevalence of periodontitis. In the fully adjusted model, participants belonging to the highest tertile of both LHR and NHR showed a notably higher likelihood of having periodontitis compared to those in the lowest tertile (LHR: OR = 1.22, 95% CI: 1.06, 1.39; NHR: OR = 1.27, 95% CI: 1.09, 1.49). Furthermore, smooth curve fitting was employed to investigate the potential nonlinear relationship between LHR, NHR, and periodontitis. The results indicated that there was a significant increase in the occurrence of periodontitis when Log2 (LHR) exceeded 1.01 and Log2(NHR) surpassed 2.16 (Log2(LHR): OR = 1.42; 95% CI: 1.19, 1.69; Log2(NHR): OR = 1.40; 95% CI: 1.15, 1.71). The subgroup analysis revealed that the associations between periodontitis and either LHR or NHR, separately, were more pronounced among individuals under the age of 50 and those without hypertension. CONCLUSIONS: This cross-sectional study revealed a positive relationship between LHR、NHR and periodontitis, particularly when these indicators exceeded their thresholds. LHR and NHR may serve as potential inflammatory markers for identifying periodontitis, thereby facilitating early warning for both patients and dentists, and enabling early intervention in the oral environment. Besides, extensive prospective cohort investigations are essential to confirm and solidify this observation.
