Purpose: The objective of this research was to examine the relationship between non-HDL cholesterol/HDL cholesterol ratio (NHHR) and vitamin D in type 2 diabetes mellitus (T2DM). Patients and Methods: This study enrolled 617 T2DM participants. Participants were separated into two groups: no vitamin D deficiency and vitamin D deficiency. Participants were split into two categories: individuals who had a high NHHR and those with a low NHHR, with the median NHHR serving as the cut-off. Eventually, the study participants were classified into two groups by gender, which were further classified into vitamin D deficient and non-vitamin D deficient groups. Results: NHHR values were substantially greater in vitamin D deficient group than in the non-deficient group in both male and female T2DM patients (P<0.05). The high NHHR group displayed substantially lower vitamin D levels than the low NHHR group [16.21 (12.55,21.35) vs 19.05 (14.59,24.07), P<0.001]. NHHR was discovered to be negatively and independently associated with vitamin D levels, and there was no sex difference. Conclusion: For the first time, our research revealed a negative relationship between NHHR and vitamin D in patients with T2DM. Keywords: vitamin D, diabetes, type 2 diabetes, lipid ratio, non-HDL-C /HDL-C

Background The ratio of nonhigh‐density lipoprotein cholesterol (non‐HDL‐C) to high‐density lipoprotein cholesterol (HDL‐C) has been shown associated with various metabolic diseases and atherosclerosis in primary prevention. However, there is limited evidence on the relationship between the non‐HDL‐C/HDL‐C ratio and progression of nonculprit coronary lesion (NCCL) after percutaneous coronary intervention (PCI). Hypothesis Our study aimed to investigate the potential association between the non‐HDL‐C/HDL‐C ratio and NCCL progression in patients with acute coronary syndrome (ACS) undergoing PCI. Methods We conducted a retrospective analysis of ACS patients who underwent coronary angiography twice at a single center from 2016 to 2022. Lipid measurements, demographic, clinical, and other laboratory data were collected from electronic medical records. NCCLs were evaluated using quantitative coronary angiography. The primary outcome was the progression of NCCL. Patients were categorized based on NCCL progression and tertiles of the non‐HDL‐C/HDL‐C ratio. Associations were analyzed using univariate and multivariate logistic regression analysis. Results The study included 329 ACS patients who underwent PCI, with a median follow‐up angiography of 1.09 years. We found NCCL progression in 95 (28.9%) patients with acceptable low‐density lipoprotein cholesterol control (median: 1.81 mmol/L). Patients in the top tertile of the non‐HDL‐C/HDL‐C ratio had a higher risk of NCCL progression. After adjusting for potential confounding factors, the non‐HDL‐C/HDL‐C ratio remained a significant predictor for NCCL progression (adjusted odds ratio: 1.45; 95% confidence interval: 1.14–1.86; p < 0.05). Conclusions The non‐HDL‐C/HDL‐C ratio predicts NCCL progression in ACS patients following PCI, providing a valuable tool for risk assessment and enhancing secondary prevention of atherosclerotic cardiovascular disease.

Purpose The ratio of non-high-density lipoprotein cholesterol (non-HDL-c) to high-density lipoprotein cholesterol (HDL-c) (NHHR) is a novel comprehensive lipid index. The aim of this study was to investigate the relationship between the NHHR and the prevalence of hyperuricaemia (HUA) in the adult population of the U.S. Methods This cross-sectional study collected data from the National Health and Nutrition Examination Survey (NHANES) (2007–2018). HUA was defined as a serum uric acid (SUA) concentration ≥ 7 mg/dL in men and ≥ 6 mg/dL in women. Multivariate logistic regression models and the restricted cubic spline (RCS) method were applied to examine the relationship between the NHHR and the risk of developing HUA. Subgroup analyses and interaction tests were also performed. Results The prevalence of HUA increased with increasing NHHR values (9.01% vs. 13.38% vs. 17.31% vs. 25.79%, P  < 0.001). The NHHR was independently correlated with the risk of developing HUA (OR = 1.10, 95% CI: 1.05–1.16; P  < 0.001). Furthermore, the risk of developing HUA was significantly greater among individuals with the highest NHHR quartile than among those with the lowest NHHR quartile (OR = 1.94, 95% CI: 1.62–2.33; P  < 0.001). This relationship was consistent across subgroups. According to the RCS analysis, an inverted U-shaped relationship existed between the NHHR and the risk of developing HUA. Conclusions The NHHR was closely associated with an increased risk of developing HUA. Further studies on the NHHR could be beneficial for preventing and treating HUA.

Background Abdominal aortic aneurysms (AAAs) can result in high mortality upon rupture but are usually undiagnosed because of the absence of symptoms in the early stage. Ultrasound screening is regarded as an impactful way to prevent the AAA-related death but cannot be performed efficiently; therefore, a target population, especially in Asia, for this procedure is lacking. Additionally, although dyslipidaemia and atherosclerosis are associated with AAA. However, it remains undetermined whether the non-high-density lipoprotein-cholesterol to high-density lipoprotein-cholesterol ratio (NHHR) is associated with AAA. Therefore, this study was aimed at examining whether NHHR is associated with AAA. Method A total of 9559 participants who underwent AAA screening at Guangdong Provincial People’s Hospital and through screening in two communities in Dongguan, from June 2019 to June 2021 joined in this screening program. The diagnosis of AAA was confirmed by the ultrasound examination of the abdominal aorta rather than any known or suspected AAA. Clinical and laboratory data of participants were collected. The participants were separated into a normal group and an AAA group according to the abdominal aortic status. To eliminate confounding factors, a propensity score matching (PSM) approach was utilized. The independent relationship between NHHR and AAA was assessed through the utilization of multivariable logistic regression analysis. In addition, internal consistency was evaluated through subgroup analysis, which controlled for significant risk factors. Results Of all the participants, 219 (2.29%) participants were diagnosed with AAA. A significant elevation in NHHR was identified in the AAA group when contrasted with that in the normal group ( P  < 0.001). As demonstrated by the results of the multivariable logistic regression analysis, AAA was independently associated with NHHR before (odds ratio [OR], 1.440, P  < 0.001) and after PSM (OR, 1.515, P  < 0.001). Significant extension was observed in the areas under the receiver operating characteristic curves (AUROCs) of NHHR compared to those of single lipid parameters before and after PSM. An accordant association between NHHR and AAA in different subgroups was demonstrated by subgroup analysis. Conclusion In the Chinese population, there is an independent association between NHHR and AAA. NHHR might be propitious to distinguish individuals with high risk of AAA.

Lipid disorders are the most common (even 70%) and worst monitored cardiovascular risk factor (only 1/4 of patients in Poland and CEE countries are on the LDL-C goal). In order to improve this the clear and easy to implement diagnostic criteria for all components of the lipid profile should be introduced. These are the updated guidelines of the two main scientific societies in Poland in the area - the Polish Society of Laboratory Diagnostics (PSLD) and the Polish Lipid Association (PoLA), which, in comparison to those from 2020, introduce few important changes in recommendations (two main lipid targets, new recommendations on LDL-C measurement, new goals for triglycerides, new recommendations on remnants and sdLDL) that should help the practitioners to be early with the lipid disorders diagnosis and monitoring (after therapy initiation), and in the consequence to avoid the first and recurrent cardiovascular events.

Background The relationship between blood lipids and cognitive function has long been a subject of interest, and the association between serum non-high-density lipoprotein cholesterol (non-HDL-C) levels and cognitive impairment remains contentious. Methods We utilized data from the 2011 CHARLS national baseline survey, which after screening, included a final sample of 10,982 participants. Cognitive function was assessed using tests of episodic memory and cognitive intactness. We used multiple logistic regression models to estimate the relationship between non-HDL-C and cognitive impairment. Subsequently, utilizing regression analysis results from fully adjusted models, we explored the nonlinear relationship between non-HDL-C as well as cognitive impairment using smooth curve fitting and sought potential inflection points through saturation threshold effect analysis. Results The results showed that each unit increase in non-HDL-C levels was associated with a 5.5% reduction in the odds of cognitive impairment (OR = 0.945, 95% CI: 0.897–0.996; p  < 0.05). When non-HDL-C was used as a categorical variable, the results showed that or each unit increase in non-HDL-C levels, the odds of cognitive impairment were reduced by 14.2%, 20.9%, and 24% in the Q2, Q3, and Q4 groups, respectively, compared with Q1. In addition, in the fully adjusted model, analysis of the potential nonlinear relationship by smoothed curve fitting and saturation threshold effects revealed a U-shaped relationship between non-HDL-C and the risk of cognitive impairment, with an inflection point of 4.83. Before the inflection point, each unit increase in non-HDL-C levels was associated with a 12.3% decrease in the odds of cognitive impairment. After the tipping point, each unit increase in non-HDL-C levels was associated with an 18.8% increase in the odds of cognitive impairment (All p  < 0.05). Conclusion There exists a U-shaped relationship between non-HDL-C and the risk of cognitive impairment in Chinese middle-aged and elderly individuals, with statistical significance on both sides of the turning points. This suggests that both lower and higher levels of serum non-high-density lipoprotein cholesterol increase the risk of cognitive impairment in middle-aged and elderly individuals.

We aimed to evaluate the association of the ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (non-HDL-C/HDL-C) and its dynamic changes with incident type 2 diabetes mellitus (T2DM). A total of 11,487 nondiabetic participants ≥18 years old in rural China were recruited in 2007–2008 and followed up in 2013–2014. A Cox proportional-hazards model was used to assess the risk of incident T2DM by quartiles of baseline non-HDL-C/HDL-C ratio and dynamic absolute and relative changes in non-HDL-C/HDL-C ratio, estimating hazard ratios (HRs) and 95% confidence intervals (CIs). Risk of incident T2DM was increased with quartiles 2, 3, and 4 versus quartile 1 of baseline non-HDL-C/HDL-C ratio (HR 1.46 [95% CI 1.08–1.98], 1.51 [1.12–2.03], and 2.16 [1.62–2.88], Ptrend < 0.001). As compared with stable non-HDL-C/HDL-C ratio during follow-up, an absolute gain in non-HDL-C/HDL-C ratio was associated with increased risk of T2DM (HR 1.67 [95% CI 1.25–2.24] for quartile 3 and 2.00 [1.52–2.61] for quartile 4). A relative increase in non-HDL-C/HDL-C ratio was also associated with increased risk of T2DM (HR 1.56 [95% CI 1.19–2.04] for quartile 3 and 1.97 [1.49–2.60] for quartile 4). Subgroup analyses showed that the association of non-HDL-C/HDL-C ratio with T2DM risk remained consistent. Increased non-HDL-C/HDL-C ratio is associated with increased risk of incident T2DM among rural Chinese adults, so the index may be an important indicator for identifying individuals at T2DM risk. •Our study explored non-HDL-C/HDL-C as a novel indicator for identifying subjects at T2DM risk based on large simple size.•We found a positive association of baseline non-HDL-C/HDL-C and its dynamic gains during follow-up with risk of T2DM.•Monitoring and reducing non-HDL-C/HDL-C ratio may be helpful to prevent and control incident T2DM.

Type 2 diabetes is widely associated with dyslipidaemia in uncontrolled patients. Prediction parameters of cardiovascular diseases have controversial issue. Therefore, the aims of this study were to investigate i) the possibility of prediction of cardiovascular diseases (CVDs) from lipoprotein ratios (TG/HDL ratio, TC/HDL ratio) and/or non-HDL level ii) the role of TyG index in prediction of CVDs in uncontrolled DM. 107 participants were recruited in this study, 34 participants were DM (32%; control) and 73 participants were uncontrolled DM (68%). HbA1c, Fasting plasma glucose, lipid profile were measured. In this study the mean age of control DM group was (50.2±2.2), and (54.1±1.6) for uncontrolled group. Weight was higher in uncontrolled DM group. FPG and HbA1c were higher in uncontrolled group. Neither LDL-C nor LDL/HDL ratio showed a significant difference between controlled DM and Uncontrolled DM. TG/HDL was elevated in uncontrolled DM. non-HDL and TyG index were significantly increased in the uncontrolled group. We concluded that neither LDL-C nor LDL/HDL ratio have a predictive role for CVDs as proposed previously. TG/HDL ratio, non-HDL, and TyG index pointed out as a useful predictive parameters for CVDs in uncontrolled T2D.

Purpose NHHR, the ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol, is a novel lipid marker associated with the risk of heart diseases and various health conditions. However, there is limited evidence regarding the relationship between NHHR and the onset of hypertension and heart diseases. The aim of this study was to investigate the association between NHHR and the new-onset hypertension and heart diseases among the Chinese middle-aged and older general population. Methods This prospective cohort study utilized data from a nationally representative sample of Chinese residents aged 45 and older, sourced from the China Health and Retirement Longitudinal Study (CHARLS). The primary outcomes of the study were new-onset hypertension and heart diseases. To investigate the relationship between the NHHR and the risk of new-onset hypertension and heart diseases, multivariate logistic regression models and the restricted cubic spline (RCS) method were employed. Additionally, the mediating effects of hypertension on the association between NHHR and heart diseases were assessed using the bootstrap method. Results A total of 5349 participants were included in the final analysis and three groups of NHHR were identified, including low-stable, medium-stable, and high-stable NHHR. By 2020, 1,631 participants (30.5%) had been newly diagnosed with hypertension, while 1233 (23.1%) developed heart diseases. Compared to those with a low-stable NHHR, individuals in the other two groups showed a significantly increased risk of developing hypertension and heart diseases. The findings remained consistent across various sensitivity analyses. According to the RCS analysis, a partial U-shaped relationship existed between the NHHR and the risk of developing hypertension and heart diseases (P for nonlinear < 0.001). Furthermore, hypertension was found to partially mediate the association between NHHR and heart diseases. Conclusion The NHHR was closely associated with an increased risk of developing hypertension and heart diseases. In addition, the NHHR partially mediated the development of heart diseases by promoting hypertension progression. In the prevention and treatment of heart diseases, managing both lipid levels and blood pressure is crucial.
