Multinational evaluation of AnthropoAge as a measure of biological age in the USA, England, Mexico, Costa Rica, and China: a population-based longitudinal study

1 year ago
We validated AnthropoAge, a biological age (BA) metric, for prediction of mortality and age-related outcomes using harmonized data from the US, England, Mexico, Costa Rica, and China. We estimated AnthropoAge and AnthropoAgeAccel as proxies of BA and age acceleration using body mass index and waist-to-height ratio. We compared mortality prediction of AnthropoAge vs. chronological age (CA) using Cox models and assessed its association with age-related outcomes with generalized estimating...

Mechano-energetic uncoupling in heart failure

1 year ago
Heart failure (HF) is a major global and life-threatening disease. Despite advances in therapies, the prevalence of HF is increasing owing to an ageing population and the pervasive pandemic of obesity and metabolic disorders, which have transformed the pathophysiology of HF. Changes in cardiac energy metabolism and the related energy deficit crucially contribute to the severity and type of HF. Furthermore, perturbations in excitation-contraction coupling, mitochondrial function and oxidative...

Cardiac intermediary metabolism in heart failure: substrate use, signalling roles and therapeutic targets

1 year ago
The number of patients with heart failure is expected to rise sharply owing to ageing populations, poor dietary habits, unhealthy lifestyles and improved survival rates from conditions such as hypertension and myocardial infarction. Heart failure is classified into two main types: heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). These forms fundamentally differ, especially in how metabolism is regulated, but they also have shared...

The future of biomarkers for vascular contributions to cognitive impairment and dementia (VCID): proceedings of the 2025 annual workshop of the Albert research institute for white matter and cognition

1 year ago
Advances in biomarkers and pathophysiology of vascular contributions to cognitive impairment and dementia (VCID) are expected to bring greater mechanistic insights, more targeted treatments, and potentially disease-modifying therapies. The 2025 Annual Workshop of the Albert Research Institute for White Matter and Cognition, sponsored by the Leo and Anne Albert Charitable Trust since 2015, focused on novel biomarkers for VCID. The meeting highlighted the complexity of dementia, emphasizing that...

Saliva as a potential diagnostic medium: DNA methylation biomarkers for disorders beyond the oral cavity

1 year ago
Saliva is an accessible biofluid with potential for non-invasive disease diagnostics. This study explores how genetic susceptibility to common diseases is reflected in DNA methylation (DNAm) and gene expression profiles in saliva. We constructed cis-mQTL (n = 345) and cis-eQTL (n = 277) datasets and examined correlations between DNAm and gene expression. Saliva QTLs were integrated with summary statistics from 36 genome-wide association studies (GWAS) using Summary-based Mendelian Randomization...
