RESUMEN
Introduction Endometrial cancer (EC) is the most common gynecological malignancy in developed countries worldwide. Its incidence is rising, making it a significant public health concern. The relationship between lipids, hyperglycemia, and anthropometric risk factors in the development of EC has gained increasing attention in recent years. Understanding the role of dyslipidemia as a part of metabolic syndrome is crucial for developing effective prevention and treatment strategies for EC. We investigate the association between dyslipidemia, hyperglycemia, and EC. This study aims to elucidate the potential contribution of altered lipid profiles and chronic hyperglycemia to endometrial carcinogenesis. By analyzing patients with benign and malignant endometrial pathologies, we seek to identify novel biomarkers and unravel the underlying mechanisms by which these metabolic factors influence the risk of developing EC. Material and methods Our retrospective unicentric study included 390 patients (192 diagnosed with EC and 198 with endometrial hyperplasia), in which we compared the clinical and biochemical characteristics, with a particular focus on lipid profiles and glycemic indices sampled 24-48 hours before surgery. The data obtained from the medical records were analyzed using statistical methods to compare selected metabolic factors between EC and endometrial hyperplasia. Results Our analysis revealed statistically significant differences in metabolic health and lipid profiles between patients diagnosed with EC and those with endometrial hyperplasia. The EC group exhibits trends towards higher levels of triglycerides (TG) and glycated hemoglobin, alongside a higher BMI. Notably, high-density lipoprotein cholesterol levels were lower in the EC group. Conclusion Although the triglycerides-to-fasting blood glucose index and the triglycerides-to-high-density lipoprotein cholesterol ratio did not demonstrate sufficient discriminatory power for predicting myometrial invasion depth in this study, further exploration of cost-effective emerging biomarkers warrants investigation in future studies.
RESUMEN
OBJECTIVE: The connection between triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) ratio and stroke risk is controversial. Our goal was to explore this relationship in individuals aged 45 and older enrolled in the China Health and Retirement Longitudinal Study (CHARLS). METHODS: Our analysis encompassed 10,164 participants from the CHARLS cohorts. We applied the Cox proportional-hazards regression model to evaluate the potential correlation between the TG/HDL-C ratio and stroke incidence. Using a cubic spline function and smooth curve fitting within the Cox model allowed us to unearth a possible non-linear pattern in this relationship. We also conducted thorough sensitivity and subgroup analyses to deepen our understanding of the TG/HDL-C ratio's impact on stroke risk. RESULTS: Adjusting for various risk factors, we observed a significant link between the TG/HDL-C ratio and increased stroke risk in individuals aged 45 and above (HR: 1.03, 95% CI 1.00-1.05, P = 0.0426). The relationship appeared non-linear, with an inflection at a TG/HDL-C ratio of 1.85. Ratios below this threshold indicated a heightened stroke risk (HR: 1.28, 95% CI 1.06-1.54, P = 0.0089), while ratios above it did not show a significant risk increase (HR: 1.01, 95% CI 0.98-1.04, P = 0.6738). Sensitivity analysis confirmed the robustness of these findings. Notably, non-smokers exhibited a stronger correlation between the TG/HDL-C ratio and stroke risk compared to past and current smokers. CONCLUSION: Our investigation revealed a significant, yet non-linear, association between the TG/HDL-C ratio and the incidence of stroke among individuals aged 45 and above. Specifically, we found that stroke risk increased in correlation with TG/HDL-C ratio below the threshold of 1.85. These insights may guide healthcare providers in advising and developing more effective strategies for stroke prevention in this demographic.
RESUMEN
OBJECTIVE: The current body of evidence on the association between the ratio of triglycerides to high-density lipoprotein cholesterol (TG/HDL-c) and the reversal of prediabetes to normoglycemia remains limited. The aim of this study is to investigate the association between TG/HDL-c and the reversion to normoglycemia in patients with prediabetes. METHODS: This retrospective cohort study included 15,107 individuals with prediabetes from 32 Chinese districts and 11 cities who completed health checks from 2010 to 2016. The Cox proportional-hazards regression model examined baseline TG/HDL-c and reversion to normoglycemia from prediabetes. Cox proportional hazards regression with cubic spline functions and smooth curve fitting determined the non-linear connection between TG/HDL-c and reversion to normoglycemia. We also ran sensitivity and subgroup analysis. By characterizing progression to diabetes as a competing risk for the reversal of prediabetes to normoglycemic event, a multivariate Cox proportional hazards regression model with competing risks was created. RESULTS: Upon adjusting for covariates, the findings indicate a negative association between TG/HDL-c and the likelihood of returning to normoglycemia (HR = 0.869, 95%CI:0.842-0.897). Additionally, a non-linear relationship between TG/HDL-c and the probability of reversion to normoglycemia was observed, with an inflection point of 1.675. The HR on the left side of the inflection point was 0.748 (95%CI:0.699, 0.801). The robustness of our results was confirmed through competing risks multivariate Cox's regression and a series of sensitivity analyses. CONCLUSION: The present study reveals a negative and non-linear correlation between TG/HDL-c and the reversion to normoglycemia among Chinese individuals with prediabetes. The findings of this study are anticipated to serve as a valuable resource for clinicians in managing dyslipidemia in prediabetic patients. Interventions aimed at reducing the TG/HDL-c ratio through the reduction of TG or elevation of HDL-c levels may substantially enhance the likelihood of achieving normoglycemia in individuals with prediabetes.

Increased triglycerides (TG) and decreased high-density lipoprotein cholesterol (HDL-C) are dyslipidemias characteristic of diabetes. Here, we aimed to examine associations of TG/HDL-C ratio with cardiovascular disease (CVD) and kidney dysfunction among patients with diabetic nephropathy. This retrospective observational study consists of patients with biopsy-proven diabetic nephropathy at Nara Medical University Hospital. Exposure of interest was TG/HDL-C ratio measured at kidney biopsy. Outcome variables were kidney histological findings, incident CVD and end-stage kidney disease (ESKD). Multivariable logistic regression models and Cox proportional hazard models were used to examined these associations. A total of 353 subjects were divided into quartiles based on TG/HDL-C ratio: Quartile 1 (reference), <1.96; Quartile 2, 1.96-3.10; Quartile 3, 3.11-4.55; and Quartile 4, ≥4.56. TG/HDL-C ratio was not a predictor of any histological findings in fully adjusted models. During median follow-up periods of 6.2 and 7.3 years, 152 and 90 subjects developed CVD and ESKD, respectively. Higher TG/HDL-C ratio was independently associated with higher incidences of CVD even after adjustments for potential confounders (hazard ratio [95% confidence interval] for Quartile 3 vs. reference; 1.73 [1.08-2.79] and Quartile 4 vs. reference; 1.86 [1.10-3.17]). Although there was a weak association between TG/HDL-C ratio and ESKD in the univariable model, the association was not significant in fully adjusted models. In conclusion, among patients with biopsy-proven diabetic nephropathy, higher TG/HDL-C ratio was independently associated with higher incidences of CVD but not with kidney outcomes, suggesting different impact of TG/HDL-C ratio on cardiorenal outcomes.

Background: The triglycerides-glucose index (TyG) and the triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) are simple indicators for assessing insulin resistance in epidemiological studies. We aimed to clarify the relationship between indicators of insulin resistance and prognosis in non-diabetic acute myocardial infarction (AMI) patients. Methods: A total of 1,648 AMI patients without diabetes were enrolled from the Department of Cardiology, Zhongda Hospital, between 2012.03 and 2018.12. The medical history, laboratory and imaging data of patients were collected through the medical record system, and all-cause death events were recorded. Pearson analysis was used to study the correlation among different variables. Logistic regression analysis was used to analyze the predictive effect of TyG and TG/HDL-C in in-hospital death of AMI patients. Results: 1. In AMI group, the TyG index was significantly increased in death groups compared to no-death groups (P = 0.025). TG/HDL-C was not significantly increased in the death group of AMI patients (P = 0.588). The patients were respectively divided into Q1-Q4 groups and T1-T4 groups according to the quartiles of TyG and TG/HDL-C. The trends of in-hospital mortality in the Q4 group of TyG and T4 group of TG/HDL-C were higher than in other groups, although these differences were not significant. 2. Pearson correlation analysis showed that TyG was positively correlated with lipid-related markers, including ApoB (r = 0.248, P < 0.001), total cholesterol (TC) (r = 0.270, P < 0.001), low-density lipoprotein cholesterol (LDL-C) (r = 0.238, P < 0.001). Spearman analysis showed that TG/HDL-C was also positively associated with TC (r = 0.107, P < 0.001), ApoB (r = 0.180, P < 0.001) and LDL-C (r = 0.164, P < 0.001). 3. Logistic regression analysis showed that TyG (OR = 3.106, 95% CI [2.122-4.547], P < 0.001) and TG/HDL-C (OR = 1.167, 95% CI [1.062-1.282], P = 0.001) were both important factors to predict the in-hospital death of AMI patients without diabetes. Conclusions: TyG index and TG/HDL-C, as emerged simple markers of insulin resistance, were both important predictors of in-hospital death in AMI patients without diabetes.

BACKGROUND: We aim to evaluate the four surrogate markers of insulin resistance (IR), including triglyceride-glucose index (TyG), lipid accumulation product index (LAP), visceral adiposity index (VAI), triglycerides to high-density lipoprotein cholesterol ratio (TG/HDL), on prevalence of chronic kidney disease (CKD) and to examine any possible effect modifiers in Chinese hypertensive patients. METHODS: A total of 13,055 hypertensive participants were included in this cross-sectional study. In addition, average age of the study population was 63.81 ± 9.46 years, and 47.66% of them are men. The primary outcome was CKD, defined as eGFR <60 ml/min/1.73 m2. Multivariate logistic regression analysis and the generalized additive model and a fitted smoothing curve (penalized spline method) were used to examine the association between the surrogate markers of IR and CKD. RESULTS: Four surrogate markers of IR were independently and positively associated with CKD in a dose-response fashion. The association between four surrogate markers of IR and the prevalence of CKD was examined as a continuous variable per one unit increment and also as a categorical variable using tertiles with the tertiles (T1) as the reference group. In the fully adjusted model, multivariate logistic analyses showed that the per one unit increments of the TyG, LAP, VAI, and TG/HDL ratios were all significantly associated with 42, 31, 67, and 78% higher risk for CKD, respectively. Consistently, the adjusted ORs (95% CI) for CKD were 1.48 (1.21, 1.81), 1.34 (1.06, 1.69), 1.26 (1.03, 1.53), 1.35 (1.12, 1.63) when comparing the highest tertile to the lowest tertile of the TyG, LAP, VAI, and TG/HDL ratios, respectively. The stratification analysis showed that a significant positive correlation between TyG, VAI, and TG/HDL and CKD in patients over 65 years old. CONCLUSION: Four surrogate markers of IR were independently and positively correlated with CKD, and LAP was better than the other surrogate markers of IR for predicting CKD. Only among participants aged over 65 years were higher levels of TyG, VAI and TG/HDL found to be closely related to the increased prevalence of CKD.
RESUMEN
BACKGROUND: Previous studies show that abnormal lipoprotein metabolism can increase the prevalence of chronic kidney disease (CKD). This study prospectively investigated the association of triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) ratio and renal dysfunction in the Chinese population. METHODS: This longitudinal cohort research examined 7,316 participants (age range: 22-93) from the China Health and Retirement Longitudinal Study (CHARLS), including 6,560 individuals with estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m2 (normal renal function, NRF) group and 756 with eGFR < 60 mL/min/1.73 m2 (impaired renal function, IRF) group. In NRF group, reduction in renal function was defined as eGFR < 60 mL/min/1.73 m2 at exit visit and in IRF group, it was defined as decline in eGFR category, average eGFR decline > 5 mL/min/1.73 m2 per year or > 30 % decrease in eGFR from baseline. RESULTS: The study results showed that TG/HDL-C ratio was positively associated with the risk of renal function decline in the NRF group (OR 1.30, 95 %CI 1.03-1.65, P = 0.03) and the IRF group (OR 1.90, 95 %CI 1.21-3.23, P = 0.02) when adjusting for age, gender, obesity, diabetes, hypertension, waist circumference, drinking, smoking, history of heart disease and stroke, low-density lipoprotein cholesterol and eGFR category. Analysis of the IRF group indicated that relative to the group of TG/HDL-C < 1.60, the group of TG/HDL-C ≥ 2.97 had an increased risk for the decline of eGFR category (OR 1.89, 95 %CI 1.12-3.21, P = 0.02) and > 30 % decline in eGFR (OR 2.56, 95 %CI 1.05-6.38, P = 0.04). CONCLUSIONS: The high TG/HDL-C ratio was an independent risk factor for declining renal function in the Chinese population.

Background and objectives: Insulin resistance (IR) is frequently associated with chronic low-grade inflammation and has an important role as a mediator in the development of liver disease. Thus, this study aimed to explore the relationship between two indexes of IR and abnormal liver function parameters. Materials and Methods: This cross-sectional study obtained data of 41,510 men and 92,357 women aged ≥30 years from a private health screening institute in Taiwan. Two IR indexes namely triglyceride-glucose (TyG) index and triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) ratio were used to examine their relationship to predict abnormal liver function parameters (aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP)). Results: Positive trend was shown for the association of TyG index in the highest quintile (Q5) and risk of high AST (OR = 1.45, 95% CI: 1.33-1.57), high ALT (OR = 1.85, 95% CI: 1.73-1.97), high GGT (OR = 2.04, 95% CI: 1.93-2.15), and high ALP (OR = 1.13, 95% CI: 1.07-1.19) compared with the median quintile (Q3) in the fully adjusted model. Similarly, participants in the Q5 of the TG/HDL-C ratio were associated with 1.38 (95% CI: 1.27-1.49), 1.71 (95% CI: 1.61-1.82), 1.75 (95% CI: 1.66-1.84), and 1.21 (1.16-1.27) odds for having high AST, ALT, GGT, and ALP respectively. The AUC (95% CI) value of the TyG index for predicting high AST, high ALT, and high GGT was 0.699 (0.692-0.705), 0.738 (0.734-0.742), and 0.752 (0.749-0.755), respectively. Meanwhile, the AUC (95% CI) of the TG/HDL-C ratio for predicting high AST, high ALT, and high GGT was 0.680 (0.673-0.686), 0.738 (0.734-0.742), 0.734 (0.731-0.738), respectively. Conclusions: Our study supported that the TyG index and TG/HDL-C ratio may be useful as non-invasive methods to predict the existence of impaired liver function in the early stage.

BACKGROUND: Elevated triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) ratio has been utilised as a predictor of outcomes in patients with adverse cardiometabolic risk profiles. In this study, we examined the prognostic value of elevated TG/HDL-C level in an Australian population of patients with high clinical suspicion of coronary artery disease (CAD) presenting for coronary angiography. METHODS: Follow-up data was collected for 482 patients who underwent coronary angiography in a prospective cohort study. The primary endpoint was all-cause mortality and the secondary endpoint was a major adverse cardiac event (MACE). Patients were stratified into two groups according to their baseline TG/HDL-C ratio, using a TG/HDL-C ratio cut point of 2.5. RESULTS: The mean follow-up period was 5.1 ± 1.2 years, with 49 all-cause deaths. Coronary artery disease on coronary angiography was more prevalent in patients with TG/HDL-C ratio ≥2.5 (83.6% vs. 69.4%, p = 0.03). On the Kaplan-Meier analysis, patients with TG/HDL-C ratio ≥2.5 had worse long-term prognosis (p = 0.04). On multivariate Cox regression adjusting for established cardiovascular risk factors and CAD on coronary angiography, TG/HDL-C ratio ≥2.5 was an independent predictor of long-term all-cause mortality (hazard ratio [HR] 2.10, 95% confidence interval [CI] 1.04-4.20, p = 0.04). On multivariate logistic regression adjusting for known cardiovascular risk factors and CAD on coronary angiography, TG/HDL-C ratio ≥2.5 was strongly associated with an increased risk of long-term MACE (odds ratio [OR] 2.72, 95% CI 1.42-5.20, p = 0.002). CONCLUSIONS: Elevated TG/HDL-C ratio is an independent predictor of long-term all-cause mortality and is strongly associated with an increased risk of MACE.

Background: Insulin resistance (IR) is the common pathophysiology of prehypertension and prediabetes. Recognition of IR in one of the two disease states is critical for carrying out preventive strategies of another disease state. This study aimed to explore which simple IR indexes were significantly associated with prehypertension in subjects with normoglycemia. Methods: A total of 108,370 adults without elevated fasting plasma glucose and hypertension were included in this study. The three simple IR indexes [triglycerides to high-density lipoprotein cholesterol ratio, the product of fasting triglycerides and glucose, and metabolic score for IR (METS-IR)] were calculated. Partial correlation was used to analyze the correlation between the three indicators and blood pressure (BP) levels, and logistic regression analysis was used to explore their association with prehypertension. Results: Among the three indicators, only METS-IR had positive correlations with systolic and diastolic blood pressure levels. Furthermore, METS-IR was also significantly associated with prehypertension, irrespective of the categorization of waist circumference (WC). The odds ratios of the highest quartile were 2.223 (95% confidence interval [CI]: 2.044-2.417) in all subjects, 2.022 (95% CI: 1.501-2.725) in elevated WC subgroup, and 1.815 (95% CI: 1.620-2.034) in normal WC subgroup. Conclusions: METS-IR was associated with prehypertension in normoglycemic Chinese subjects, which bypasses the impact of WC and might be valuable for the management of prehypertension and the prevention of prediabetes in different ethnic groups.

Raised triglycerides (TG) and reduced high density lipoprotein cholesterol (HDL-c) are components of metabolic syndrome. Both high TG and metabolic syndrome have been reported to be risk factors of endometrial cancer. Therefore, triglycerides-to-high density lipoprotein cholesterol ratio (TG/HDL-c ratio) may be a useful biological indicator in managing endometrial cancer. We aimed to explore the association between pretreatment TG/HDL-c ratio and endometrial cancer in postmenopausal women, and to evaluate its potential role in the disease. Pretreatment serum lipid profile and TG/HDL-c ratio were retrospectively analyzed for 167 postmenopausal women with endometrial cancer and 464 matched noncancer controls. Compared with controls, pretreatment TG/HDL-c ratio in endometrial cancer patients significantly elevated regardless of whether patients had diabetes or overweight/obesity (P < 0.05). Further analyses showed that pretreatment TG/HDL-c ratio increased significantly with advanced tumor stage. Interestingly, TG/HDL-c ratio of type I endometrial cancer patients was higher than those with type II endometrial cancer. A positive association was found between pretreatment TG/HDL-c ratio and tumor stage (adjusted r = 0.176, P = 0.027) in endometrial cancer group. Receiver operating characteristic curve analysis yielded the cut-off value of 1.52 for TG/HDL-c ratio to discriminate patients with cancer from controls (area under the curve, 0.689; sensitivity, 51.5%; specificity, 84.1%). Multivariate logistic regression model identified TG/HDL-c ratio ≥ 1.52 (odds ratio = 4.123; P < 0.001) as an independent predictor of endometrial cancer. TG/HDL-c ratio was positively associated with endometrial cancer clinical features, such as tumor stage and pathogenetic type. Accordingly, pretreatment TG/HDL-c ratio might be a potential marker for endometrial cancer.

BACKGROUND AND AIMS: The objective of this study was to evaluate the ability of lipid variables to predict the development of chronic kidney disease (CKD). We investigated the longitudinal association between lipid profiles and incident CKD in a large apparently healthy cohort. METHODS: A retrospective longitudinal analysis of 10,288 subjects who had participated in comprehensive health check-ups at least four times over a 7-year period was conducted. The risk of incident CKD associated with lipid variables was analyzed using adjusted hazard ratio (HR) for CKD per 1 standard deviation (SD) increase in lipid level. The development of CKD was defined as estimated glomerular filtration rate <60 ml/min/1.73 m(2). RESULTS: Over a mean follow-up of 56.5 ± 14.3 months, 356 (3.5%) subjects developed CKD. The multivariate adjusted HRs for incident CKD per 1 SD increase in baseline lipid level were 1.29 (95% confidence interval [CI], 1.17-1.41) for triglycerides (TG), 0.77 (0.68-0.88) for high-density lipoprotein cholesterol (HDL-C), 1.22 (1.12-1.32) for the TG/HDL-C ratio, 0.82 (0.73-0.92) for the low-density lipoprotein cholesterol/apolipoprotein B (LDL-C/apoB) ratio, and 0.74 (0.66-0.83) for the HDL-C/apoA-1 ratio. No longitudinal association was found between incident CKD and baseline total cholesterol, LDL-C, non-HDL-C, the LDL-C/HDL-C ratio, apoB, apoA-I, or the apoB/apoA-I ratio. CONCLUSIONS: The LDL-C/apoB and HDL-C/apoA-1 ratios as well as TG and HDL-C concentrations independently predicted an increased risk for developing CKD. Our findings suggest that particle size of HDLs and LDLs may contribute to the development of CKD.

BACKGROUND: The impact of the triglycerides to high-density lipoprotein cholesterol (TG:HDL-C) ratio on chronic kidney disease (CKD) is unclear. STUDY DESIGN: Longitudinal cohort study. SETTING & PARTICIPANTS: 124,700 participants aged 39 to 74 years in the Japanese Specific Health Check and Guidance System, including 50,392 men, 74,308 women, 102,900 without CKD, and 21,800 with CKD. PREDICTOR: Quartiles of TG:HDL-C ratio. OUTCOMES & MEASUREMENTS: Changes in estimated glomerular filtration rate (eGFR) and urinary protein excretion during the 2-year study period. Incident CKD in participants without CKD, and progression of CKD in participants with CKD. RESULTS: In the entire study population, higher quartile of TG:HDL-C ratio at baseline was significantly associated with greater decline in eGFR and increase in urinary protein excretion during the 2-year study period, even after adjustment for confounding factors. A higher ratio was associated with higher risk of incident CKD in participants without CKD and higher risk of rapid decline in eGFR and increase in urinary protein excretion in participants with CKD. Higher TG:HDL-C ratio was more strongly associated with decline in eGFR (P for interaction = 0.002) and with incident CKD (P for interaction = 0.05) in participants with diabetes than without diabetes. LIMITATIONS: Short observation period and single measurement of all variables. CONCLUSIONS: A higher TG:HDL-C ratio affects the decline in eGFR and incidence and progression of CKD in the Japanese population.

OBJECTIVES: To investigate the relationship between triglycerides to high-density lipoprotein cholesterol ratio (TG/HDL-C) and chronic kidney disease (CKD). METHODS: We used data from 216,007 Japanese adults who participated in a nationwide health checkup program. Men (n = 88,516) and women (n = 127,491) were grouped into quartiles based on their TG/HDL-C levels (<1.26, 1.26-1.98, 1.99-3.18, and >3.18 in men; <0.96, 0.96-1.44, 1.45-2.22, and >2.22 in women). We cross-sectionally assessed the association of TG/HDL-C levels with CKD [defined as an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m(2) (low eGFR) and/or proteinuria (defined as urinary protein ≥ 1+ on dipstick testing)], low eGFR, and proteinuria. RESULTS: The prevalence of CKD, low eGFR, and proteinuria increased significantly with elevating quartiles of TG/HDL-C in both genders (all P for trend <0.001). Participants in the highest quartile of TG/HDL-C had a significantly greater risk of CKD than those in the lowest quartile after adjustment for the relevant confounding factors (odds ratio: 1.57, 95% confidence interval: 1.49-1.65 in men; 1.41, 1.34-1.48 in women, respectively). Furthermore, there were significant associations with low eGFR and proteinuria. In stratified analysis, the risk of CKD increased linearly with greater TG/HDL-C levels in participants with and without hypertension, diabetes, and obesity. Moreover, higher TG/HDL-C levels were relevant for CKD, especially in participants with hypertension and diabetes (P for interaction <0.001, respectively). CONCLUSIONS: An elevated TG/HDL-C is associated with the risk of CKD in the Japanese population.
