Summary: Machine and deep learning survival models have comparable or better prediction capabilities for time-to-event compared to classical statistical learning methods, but they are too complex for human interpretation. This paper introduces SurvSHAP(t), the first time-dependent explanation method for interpreting survival black-box models, based on SHapley Additive exPlanations with solid theoretical foundations. The proposed method aims to improve precision diagnostics and support decision-making by domain experts.

Summary: In this study, it is pointed out that the Cox network has estimation bias when dealing with high-dimensional datasets. To address this issue, the Deep Bayesian Perturbation Cox Network (DBP) is proposed, which uses Bayesian prior knowledge to optimize the training process of the neural network. The comparison with previous models and simulation experiments demonstrate that the DBP method improves the prediction performance and can guide the discovery of disease-related genes.

Summary: The study found that reduced CFTR expression is associated with increased mortality in colorectal cancer patients. This suggests that CFTR may serve as a potential biomarker for prognosis and that individuals with low CFTR expression may benefit from more aggressive treatment. Furthermore, molecular therapies targeting CFTR activity developed for cystic fibrosis may also be applicable for colorectal cancer patients with low CFTR expression.

Summary: This study demonstrates how MRI data from the UK Biobank (UKBB) and German National Cohort (NAKO) can be jointly analyzed to derive comprehensive quantitative image-based phenotypes across the general adult population. The researchers extracted image-derived features of abdominal organs from T1-weighted Dixon MRI data and used causal discovery and batch effect correction methods to harmonize data from UKBB and NAKO. They performed quantile regression on the harmonized data, providing quantitative models for the variation of image-derived features stratified by sex and dependent on age, height, and weight.

Summary: This study conducted a pooled analysis of 19 studies and found that higher levels of seafood-derived omega 3 polyunsaturated fatty acids (n-3 PUFAs) were associated with a lower risk of incident chronic kidney disease (CKD). However, no association was found for plant-derived n-3 PUFAs. These results highlight the beneficial role of seafood-derived n-3 PUFAs in preventing CKD.

Summary: This research aimed to identify candidate metabolite biomarkers of Metabolic Syndrome (MetS) and its associated risk factors. The study identified 56 specific metabolites related to MetS, with 13 of them being positively associated and 43 being negatively associated. The majority of these metabolites were associated with low HDL-C and hypertension. Additionally, one lipid metabolite, lysoPC a C18:2, was negatively associated with MetS and its five components. The study also revealed impaired metabolism of branched-chain and aromatic amino acids, as well as accelerated Glycine catabolism through metabolic networks.

Summary: This study compared the concentration of a specific metabolite in the urine of vegans and omnivores, and found that the difference disappeared when adjusted for creatinine. However, after adjusting for creatinine, the concentration in omnivores was found to be 26% lower than in vegans. This may be due to the consumption of meat and fish as exogenous sources of creatinine.

Summary: Epidemiological studies have shown that the intake of dairy products increases levels of odd-chain fatty acids (OCFA) in humans, particularly C17:0, which is associated with a lower risk of type 2 diabetes. However, feeding mice with high-fat diets supplemented with milk fat or C17:0 did not improve lipid accumulation and insulin resistance in the liver. In fact, milk fat intake worsened liver inflammation. Treatment of primary hepatocytes with C15:0 and C17:0 suppressed JAK2/STAT3 signaling, but only C15:0 enhanced insulin-stimulated phosphorylation of AKT. Therefore, milk fat and C17:0 may not provide health benefits, while C15:0 shows promise for further studies.

Summary: This study evaluated the different associations of magnetic resonance imaging (MRI)-based paravertebral myosteatosis with lumbar disc degeneration in individuals with impaired glucose metabolism and normoglycaemic controls. The results showed a significant positive association between paravertebral myosteatosis and intervertebral disc degeneration in individuals with impaired glucose metabolism. No significant associations were found in the normoglycaemic controls. These findings emphasize the potential link between skeletal muscle and spinal-related diseases.
