Summary: Higher cardiorespiratory fitness is associated with lower risk of type 2 diabetes. Genetic determinants in cardiorespiratory fitness and candidate genes related to cardiac muscle development and muscle contractility were identified. Higher genetically predicted fitness is causally associated with lower risk of type 2 diabetes independent of adiposity.

Summary: This study aims to make the Type 2 Diabetes Knowledge Portal (T2DKP) more accessible and useful to both new and existing users. It evaluates the comprehensiveness of T2DKP by comparing its datasets with other repositories, guides researchers unfamiliar with human genetic data on how to interpret and use the data through T2DKP, and discusses the importance of democratizing access to complex disease genetic results.

Summary: This study aims to identify biomarkers of cardiomyopathy in T2DM patients and explore the associations between functional status, metabolomic profile, and myocardial fibrosis. The results show that patients with well-controlled T2DM exhibit myocardial fibrosis, which is associated with reduced exercise tolerance and specific metabolites.

Summary: Epigenetic marks the genome through DNA methylation, histone modification, or non-coding RNAs, guiding cells to respond to environmental cues and maintain stable gene expression. Studies have revealed associations between DNA methylation and conditions such as body mass index, obesity, and Type 2 Diabetes, highlighting the potential therapeutic value of epigenetic research.

Summary: This study investigated the impact of functional mitral regurgitation (FMR) on left atrial (LA) compliance in type 2 diabetes mellitus (T2DM) patients. The results showed that FMR may aggravate LA and left ventricular (LV) dysfunction in T2DM patients, and the degree of regurgitation was found to be an independent determinant of LA strain.

Summary: Type 2 diabetes accounts for nearly 90% of global diabetes cases, with an increasing number of affected individuals, particularly among young people. Early detection and proactive management are crucial for preventing complications and reducing mortality. Technology and precision medicine offer potential improvements to treatment outcomes but face significant barriers.

Summary: This paper proposes a novel deep learning framework that effectively handles neuroimaging and genetic data simultaneously, achieving state-of-the-art performance in Alzheimer's disease and mild cognitive impairment identification. Unlike existing methods, the framework learns the relationship between imaging phenotypes and genotypes in a nonlinear way without prior neuroscientific knowledge.

Summary: Type 2 diabetes is highly prevalent and contributes to cardiovascular disease. Despite significant progress in identifying genetic variation associated with T2D risk, the promise of precision medicine has not been fully realized. Recent studies have identified sub-groups of individuals with differential risk for intermediate phenotypes, which could aid in patient stratification and bridging the gap towards precision medicine for T2D.

Summary: Biomarkers are important for early detection and stratification of diabetes and its complications. In this study, we used NMR spectrometry to analyze metabolic parameters in plasma samples of healthy volunteers and diabetic patients. Our results showed independent associations between diabetes and branched-chain amino acids, lactate, linoleic acid, and HDL diameter. Additionally, we found imbalances in the concentrations of free cholesterol in different lipoprotein subclasses in diabetic subjects compared to non-diabetic controls, which may reflect disturbances in cholesterol transfer processes.

Summary: The reduced thickness of retinal pigment epithelium (RPE) is identified as a significant risk factor for future type 2 diabetes mellitus (T2DM) and its microvascular phenotypes. Analyses of circulating plasma metabolites reveal a wide range of metabolic fingerprints associated with the reduced RPE, which can improve predictability and clinical utility for stratifying future T2DM and related microvascular phenotypes, highlighting the promising role of retinas as a window to systemic health.

Summary: The study found a significant association between genetically predicted malaria risk and the prevalence of iron deficiency in African children, with a potential 49% reduction in ID if malaria episodes are halved as an intervention. Using HbAS as an instrumental variable in Mendelian randomization analyses, a 30% reduction in ID risk was observed in children living in malaria-endemic areas.

Summary: This study found that optimism was not associated with leukocyte telomere length among African American adults, and there was no evidence of effect modification by sex, age, body mass index, income, or chronic conditions. Future studies should explore alternate biological and behavioral mechanisms that may explain the association between optimism and health.

Summary: Genotype-phenotype association studies often require harmonization of data from multiple sources, which can be challenging due to data heterogeneity. A centralized system for phenotype harmonization was developed and successfully used to harmonize 63 phenotypes in the TOPMed program. The harmonized data and associated documentation have been made available for controlled access by the scientific community.

Summary: This study uses promoter capture Hi-C data to identify and characterize cell type-specific super-interactive promoters (SIPs) in blood lineage cell types. The study finds that the interaction regions of SIPs are more likely to overlap with cell type-specific ATAC-seq peaks and GWAS variants for relevant blood cell traits. Furthermore, SIP genes tend to express at a higher level in the corresponding cell type and SIP subnetworks help interpret GWAS variants. The study highlights the potential of using promoter-centric analyses to identify important genes and their regulatory regions.

Summary: This study examined the age-related changes in brain function and baseline brain structure that support motor skill acquisition. The findings showed that older adults experienced decreases in functional connectivity during motor skill acquisition, while younger adults experienced increases. Additionally, regardless of age group, lower baseline microstructure in a frontoparietal tract was associated with slower motor skill acquisition.

Recent studies have shown that even light exercise can improve memory and this improvement is mediated by the ascending arousal system. This study aimed to investigate the effects of light-intensity exercise on hippocampal memory function in healthy older adults and found that pupil dilation during exercise played a role in the memory improvement.

Summary: This study investigated the effects of age on the robustness and resilience of auditory system using the desert locust. The researchers found that gene expression changes were mainly influenced by age rather than noise exposure. Both young and aged locusts were able to recover their auditory nerve function within 48 hours of noise exposure, but the recovery of transduction current magnitude was impaired in aged locusts. Key genes responsible for robustness to noise exposure in young locusts and potential candidates for compensatory mechanisms in auditory neurons of aged locusts were identified.
