Uncovering the complex genetic architecture of human plasma lipidome using machine learning methods
Sci Rep. 2023 Feb 22;13(1):3078. doi: 10.1038/s41598-023-30168-z. ABSTRACT Genetic architecture of plasma lipidome provides insights into regulation of lipid metabolism and related diseases. We applied an unsupervised machine learning method, PGMRA, to discover phenotype-genotype many-to-many relations between genotype and plasma lipidome (phenotype) in order to identify the genetic architecture of…
Intake and sources of dietary fibre and dietary fibre fractions in Finnish children
Br J Nutr. 2023 Feb 21:1-11. doi: 10.1017/S0007114523000466. Online ahead of print. ABSTRACT The current definition of dietary fibre was adopted by the Codex Alimentarius Commission in 2009, but implementation requires updating food composition databases with values based on appropriate analysis methods. Previous data on population intakes of dietary fibre…
Associations of active commuting to school in childhood and physical activity in adulthood
Sci Rep. 2023 May 11;13(1):7642. doi: 10.1038/s41598-023-33518-z. ABSTRACT This study examined whether active commuting to school in childhood and adolescence predicted active commuting to work and overall physical activity (PA) in adulthood. Participants from the Young Finns Study (N = 2436) were aged 9-18 years in 1980 and followed up…
Workplace Psychosocial Resources and Risk of Sleep Disturbances Among Employees
JAMA Netw Open. 2023 May 1;6(5):e2312514. doi: 10.1001/jamanetworkopen.2023.12514. ABSTRACT IMPORTANCE: Workplace psychosocial resources naturally tend to cluster in some work teams. To inform work-related sleep health promotion interventions, it is important to determine the associations between clustering of workplace resources and sleep disturbances when some resources are high while others…
Gene Set Based Integrated Methylome and Transcriptome Analysis Reveals Potential Molecular Mechanisms Linking Cigarette Smoking and Related Diseases
OMICS. 2023 May;27(5):193-204. doi: 10.1089/omi.2023.0028. Epub 2023 May 5. ABSTRACT Advanced integrative analysis of DNA methylation and transcriptomics data may provide deeper insights into smoke-induced epigenetic alterations, their effects on gene expression and related biological processes, linking cigarette smoking and related diseases. We hypothesize that accumulation of DNA methylation changes…
The relationship of trait-like compassion with epigenetic aging: The population-based prospective Young Finns Study
Front Psychiatry. 2023 Apr 18;14:1018797. doi: 10.3389/fpsyt.2023.1018797. eCollection 2023. ABSTRACT INTRODUCTION: Helping others within and beyond the family has been related to living a healthy and long life. Compassion is a prosocial personality trait characterized by concern for another person who is suffering and the motivation to help. The current…
Possible heterogeneity of initial pancreatic islet beta-cell autoimmunity heralding type 1 diabetes
J Intern Med. 2023 May 4. doi: 10.1111/joim.13648. Online ahead of print. ABSTRACT The etiology of type 1 diabetes (T1D) foreshadows the pancreatic islet beta-cell autoimmune pathogenesis that heralds the clinical onset of T1D. Standardized and harmonized tests of autoantibodies against insulin (IAA), glutamic acid decarboxylase (GADA), islet antigen-2 (IA-2A),…
Physical Activity and the Development of Islet Autoimmunity and Type 1 Diabetes in 5-15-Year-Old Children Followed in the TEDDY Study
Diabetes Care. 2023 May 4:dc230036. doi: 10.2337/dc23-0036. Online ahead of print. ABSTRACT OBJECTIVE: This study investigated physical activity and its association with the development of islet autoimmunity and type 1 diabetes in genetically at-risk children aged 5-15 years. RESEARCH DESIGN AND METHODS: As part of the longitudinal Environmental Determinants of…
Gut microbiota composition and function in pregnancy as determinants of prediabetes at two-year postpartum
Acta Diabetol. 2023 Apr 28. doi: 10.1007/s00592-023-02064-5. Online ahead of print. ABSTRACT AIMS: Deep metagenomics offers an advanced tool for examining the relationship between gut microbiota composition and function and the onset of disease; in this case, does the composition and function of gut microbiota during pregnancy differ in women…
