HEBE - Healthy Aging Versus Inflamm-aging: the Role of Physical Exercise in Modulating the Biomarkers of Age-associated and Environmentally Determined Chronic Diseases. Research Line 1. Proof of Concept
The main objective of this clinical trial is to test the effects of the personalized intervention based on physical exercise, on clinical variables and circulating markers, in a population of employees of the University of Milan (UMilan).
The HEBE study will include two phases:
PHASE 1:
All UMilan employees will be asked to voluntarily complete an anonymous online questionnaire, in order to gather information about their lifestyle (physical activity, diet, cigarette smoking, etc) (zero time: T0); at the end of the compilation, indications on how to improve the lifestyle will be provided. These indications will also be present and available for consultation in a special section of the site on the "HEBE" site, with UMilan domain (www.hebe.unimi.it).
After 6 months, all UMilan employees will receive a second invitation to voluntarily complete the same questionnaire, in order to evaluate any changes, in terms of lifestyle improvement (time one: T1).
PHASE 2:
100 eligible subjects who have expressed their availability in the initial questionnaire, will be identified to undergo a lifestyle improvement protocol based mainly on the prescription of a personalized exercise program, which will define modalities, intensity, duration, frequency and progression of the exercise. For each subject, at T0 and T1 (after 6 months), biological samples will be collected (blood, urine, saliva and nasal swab), which will be used to: i) set up a biobank shared by the members of the HEBE consortium; ii) identify biomarkers able to monitor the effect of physical exercise on the characteristics of the frailty under examination. Furthermore, both at T0 and T1 questionnaires will be completed and carried out clinical evaluations (anamnesis, physical examination, tests for the study of the autonomic nervous system, bio-impedance test, evaluation/estimate of maximal oxygen consumption, ECG).
Non-communicable diseases (NCDs) are the cause of premature aging and death of 41 million people each year, accounting for 71% of all deaths globally. NCDs are closely linked to rapid urbanization and globalization. In this context, unsustainable lifestyles, characterized by a lack of physical activity, trigger the progression of NCDs. To date, it is estimated that around 41% of Europeans (and as many as 60% of Italians) do not engage in any type of physical activity (even light) during the week and this increases the risk of chronic diseases: 86% of deaths are attributable to cardiovascular disease, cancer, chronic respiratory disease and type 2 diabetes, a disease from which approximately 52 million people suffer in Europe (8.4% of men and 7.8% of women among 20 and 79 years of age).
Over the years, the progressive increase in the number of senescent cells can lead to tissue/organ dysfunction. In an attempt to respond to this process, senescent cells undergo metabolic modifications leading to increased secretion of soluble factors (e.g. cytokines, chemokines, growth factors, metalloproteases), which thus modulate their microenvironment through the removal of damaged cells by the recruitment of phagocytes and stimulating cell differentiation and proliferation for tissue renewal. The secretion of pro-inflammatory molecules and the activation of immune cells contributes to the generation of a low-grade chronic pro-inflammatory state known as "inflammaging", which is at the root of most age-related diseases. Furthermore, upregulation of mitogenic and pro-angiogenic pathways dangerously increases the risk of oncogenic transformation. The modulation of the complex of alterations that make up inflammaging could therefore be the key to guaranteeing healthy aging and reducing the risk of developing early NCD. A very promising approach to controlling inflammaging involves focusing on reducing the risk factors associated with these diseases by proposing alternative development models.
The main challenge of the HEBE project as a whole therefore consists in addressing three fundamental questions:
General objectives of the trial
The main objective of this study is the evaluation of the effects of the personalized intervention based on physical exercise, on clinical parameters and circulating markers, in a population of employees of the University of Milan (UMilan).
In Research Line 1- a pilot study will be conducted involving UMilan employees which will include two phases:
PHASE 1:
All UMilan employees will be asked to voluntarily complete an anonymous online questionnaire, in order to gather information about their lifestyle (physical activity, diet, cigarette smoking, etc.) (zero time: T0); at the end of the compilation, indications on how to improve the lifestyle will be provided. These indications will also be present and available for consultation in a special section of the site on the "HEBE" site, with UMilan domain (www.hebe.unimi.it), in a special section.
After 6 months, all UMilan employees will receive a second invitation to voluntarily complete the same questionnaire, in order to evaluate any changes, in terms of lifestyle improvement (time one: T1).
PHASE 2:
100 eligible subjects who have expressed their availability in the initial questionnaire, will be identified to undergo a lifestyle improvement protocol based mainly on the prescription of a personalized exercise program, which will define modalities, intensity, duration, frequency, and progression of the exercise. For each subject, at T0 and T1 (after 6 months), biological samples will be collected (blood, urine, saliva and nasal swab), which will be used to: i) set up a biobank shared by the members of the HEBE consortium; ii) identify biomarkers able to monitor the effect of physical exercise on the characteristics of the frailty under examination. Furthermore, both at T0 and T1 questionnaires will be completed and carried out clinical evaluations (anamnesis, physical examination, tests for the study of the autonomic nervous system, bio-impedance test, evaluation/estimate of maximal oxygen consumption, ECG) useful for: i) verifying the clinical conditions of the subject; ii) obtain useful parameters for the customized definition of the intervention program; iii) verify the effectiveness of the intervention at T1; iv) assess the association between clinical indicators and biomarkers.
