Causal effects of circulating lipids and lipid-lowering drugs on the risk of atopic dermatitis: a mendelian randomization study.

Lipid metabolism disorders are frequently noted in atopic dermatitis (AD) patients, prompting the long-term use of lipid-lowering drugs. However, the causal effects of circulating lipids and different lipid-lowering drugs on the risk of AD are not thoroughly understood. Using publicly available genome-wide association studies (GWAS) summary data from two different cohorts, a series of Mendelian randomization (MR) analyses were conducted to explore the causal effects of genetically proxied circulating lipids and lipid-lowering drugs on the risk of AD.

Generalized Centered 2-D Principal Component Analysis.

Most existing robust principal component analysis (PCA) and 2-D PCA (2DPCA) methods involving the l -norm can mitigate the sensitivity to outliers in the domains of image analysis and pattern recognition. However, existing approaches neither preserve the structural information of data in the optimization objective nor have the robustness of generalized performance. To address the above problems, we propose two novel center-weight-based models, namely, centered PCA (C-PCA) and generalized centered 2DPCA with l -norm minimization (GC-2DPCA), which are developed for vector- and matrix-based data, respectively.
