Applied Clinical Biosemiomics to Promote Longevity (Part 2.- in silico Capillaroscopy of Premature Aging)

Premature aging is a multifactorial process determined by the cumulative interaction among environmental exposures, lifestyle habits, metabolic alterations, and molecular mechanisms capable of modifying cellular homeostasis. The objective of this research was to develop a mechanistic, observational, analytical, and proposal-oriented model that integrates risk factors, cellular senescence, microcirculation, and Applied Clinical Biosemiomics to study premature biological aging. The methodology was structured in eight progressive stages: multivariable modeling of exogenous and endogenous factors; experimental in vivo–in silico correlation; epidemiological and longitudinal analysis; corroboration using biomarkers; correlation of capillaroscopic patterns with age; construction of the Integrated Index of Premature Biological Aging (IIEBP); integration of omics sciences; and evaluation of clinical, pharmacological, and nutraceutical interventions. The IIEBP proposes five domains: exposome burden, metabolic, molecular, senescent, and morphofunctional. Under the methodology of the ATDM System, capillaroscopy is proposed as a tool for transforming qualitative morphofunctional characteristics into quantifiable variables and correlating them with risk factors and independent biomarkers. Applied Clinical Biosemiomics organizes these relationships through the sequence exposure–molecular perturbation–cellular response–tissue modification–capillaroscopic sign, maintaining the distinction between an observable sign and a causal mechanism. In vivo–in silico integration will allow hypotheses on the convergence, progression, and potential reversibility of alterations to be generated and tested. The model thus establishes a stepwise strategy to identify modifiable mechanisms, develop integrated biomarkers, and evaluate interventions aimed at preventing functional deterioration, reducing the acceleration of biological aging, and promoting healthy longevity.
