Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Recently, numerous signaling proteins derived from adipose tissue and/or skeletal muscle have been described and are involved in the pathogenesis of obesity and the pathophysiology of aging. Current evidence suggests a role for the FGF-Klotho system, circulating cell-free DNA (cfDNA), miR-499, and exosomes not only in the pathophysiology of obesity, but also in the association with sarcopenic obesity (OS) and in a accelerated aging.

The investigator´s hypothesis is that obesity, especially OS, might be the cause of advanced aging, reflected in lower levels of the FGF-Klotho system, higher concentrations of cfDNA and a change in the profiles of miRNAs and exosomes, which could have an impact on risk. cardiovascular and metabolic.

For this, a descriptive cross-sectional study is proposed in 50 patients with obesity, who will be classified as OS or not, and 25 healthy controls, between 50-60 years old. The determinations are made by the IBIOMED of the University of León.

To study the evolution of aging markers over a year of follow-up, a second part of the study will analyze the possible differences according to the treatments assigned to each patient in the context of real life (lifestyle changes, drugs, bariatric surgery).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Descriptive cross-sectional study in patients with obesity attended in the High-Risk Obesity consultation of the University Assistance Complex of León, with a control group of healthy people of the same age group without obesity or cardiovascular risk factors that will be selected among volunteers from the CAULE and University of Leon staff.

The second part of the study will be a one-year prospective longitudinal follow-up study of the patients included in the first part of the study.
