The ratio of non-high-density lipoprotein cholesterol to high-density (NHHR) is a novel marker related atherosclerosis, but its role in diabetic kidney disease (DKD) remains unclear. This study investigated the relationship between NHHR and DKD risk patients with type 2 diabetes mellitus (T2DM) evaluated potential as for early screening. Data from adults T2DM participating National Health Nutrition Examination Surveys (NHANES) 1999 2018 were analyzed. Demographic information, laboratory tests, other relevant information collected. To evaluate correlation levels risk, weighted multivariable logistic regression restricted cubic spline (RCS) analyses employed. Furthermore, threshold effect analysis was employed further explore at different levels, subgroup validated results. enrolled total 3,243 participants, comprising 1,258 individuals (38.79%) 1,985 without (61.21%). showed that higher exhibited 45% reduction developing comparison those lower (Q2 vs. Q1: OR 0.55, 95% CI 0.40-0.76).

Patients with diabetic nephropathy (DN) often present lipid profile abnormalities. While associations between these parameters and DN have been suggested, confounding factors obscure causal relationships. This study employed bidirectional Mendelian randomization (MR) to explore links. Using genome-wide association (GWAS) data, the primary analysis used inverse-variance weighted (IVW) method, which was supported by MR-Egger regression a median estimator (WME). Sensitivity analyses, including heterogeneity, pleiotropy tests, leave-one-out, reverse causality were conducted. The IVW model revealed following: (1) relationships triglycerides (TG) (OR: 1.5807, 95% CI: 1.2578–1.9865, P = 0.0001), high-density lipoprotein cholesterol (HDL-C) 0.7342, 0.5729–0.9409, 0.0146), apolipoprotein A1 (ApoA1) 0.6506, 0.5190–0.8156, 0.0002) DN; (2) TG 1.0607, 1.0143–1.1093, 0.0098), HDL-C 0.9453, 0.9053–1.9871, 0.0109), B (ApoB) 1.0672, 0.0070–1.1310, 0.0280) urinary albumin–creatinine ratio (UACR); (3) no relationship total (TC), low-density (LDL-C), ApoB DN, or TC, LDL-C, ApoA1 UACR; (4) none of results showed causality. is risk factor for protective both; protects against UACR.

This study introduces SMOTE-PCA-HDBSCAN, novel oversampling framework that integrates the Synthetic Minority Oversampling Technique (SMOTE) generate synthetic samples, Principal Component Analysis (PCA) enhance data separability, Hierarchical Density-Based Spatial Clustering of Applications with Noise (HDBSCAN) remove noise. The cleaned is then merged original dataset form balanced, noise-reduced training set. Comparative evaluations against SMOTE, SMOTE-DBSCAN, SMOTE-PCA-DBSCAN, SMOTE-ENN, SMOTE-Tomek Links reveal SMOTE-PCA-HDBSCAN consistently improves sensitivity classes (Clean: 4.76% 28.57%; Polluted: 38.09% 61.90%) while maintaining high majority class.
