Cross-population validation of statistical distance as a measure of physiological dysregulation during aging
Abstract: Measuring physiological dysregulation during aging could be a key tool both to understand underlying aging mechanisms and to predict clinical outcomes in patients. However, most existing indices are either circular ...
Inflamm‐aging does not simply reflect increases in pro‐inflammatory markers
Abstract: Many biodemographic studies use biomarkers of inflammation to understand or predict chronic disease and aging. Inflamm-aging, i.e. chronic low-grade inflammation during aging, is commonly characterized by ...
The risks of one-at-a-time biomarker epidemiology: Associations of circulating calcium levels with age, mortality, and frailty vary substantially across populations
Abstract: Recent studies have shown contradictory associations between calcium levels and health outcomes. We suspected these conflicting results were the consequence of more general issues with how biomarkers are analyzed ...
Statistical distance as a measure of physiological dysregulation is largely robust to variation in its biomarker composition
Physiological dysregulation may underlie aging and many chronic diseases, but is chal-lenging to quantify because of the complexity of the underlying systems. Recently, we de-scribed a measure of physiological dysregulation, ...
Detection of a novel, integrative aging process suggests complex physiological integration
Abstract: Many studies of aging examine biomarkers one at a time, but complex systems theory and network theory suggest that interpretations of individual markers may be context-dependent. Here, we attempted to detect ...
