The role of immune response in ageing and longevity. A focus on B cell compartment

2017

The improvement of the quality of life of elderly people is going to become a priority because of the continuous increase in the number of centenarians. This render the studies of the processes involved in ageing of critical importance. Centenarians are a widely accepted model of successful ageing, a complex process which is influenced by several biological, environmental and lifestyle factors, because they have reached the extreme limits of life span overcoming the major age-related diseases. In centenarians model, several aspects have been studied, as inflammation, immune system, genetics and metabolism, to understand the secret of their long survival. It has been proposed that centenaria…

Bioimpedance: a new approach for studying longevity

2017

Centenarians are the best model to study successful ageing. Unfortunately, they are rare and do not have an aged-matched control population to compare their exceptional characteristics with non-longevous people. Considering the complexity of molecular studies, the opportunity to analyse the centenarian phenotype with anthropometry could be an easy and no invasive interesting solution to identify peculiar measurable variables. In addition to the classic measurements, the bioelectrical impedance could be considered. This method permits to analyse the body composition, in terms of fat free mass and fat mass. Ageing is related to reduced fat free mass and increased body fat. The reduction of th…

Longevity hotspot in Sicily. The exploration of a new possible blu zone

We are conducting a survey in some mountainous Sicilian populations, particularly in villages sited in the Palermo province, part of the Madonie Park. To ascertain the true longevity rate, we checked the born and death registers, analyzing about 37,000 newborns between 1881 and 1917 in a sample of five small municipalities located in Madonie. About 1,700 individuals died at the age of 90 years and over, and about one hundred were centenarians. Therefore, the probability to reach 90 and 100 years old was of 4.6% and 0.22% respectively. Accordingly, we observed significant lower mortality rates for all causes of death when compared to those measured in Palermo town. Therefore, the population …

Phenotypic Aspects of Longevity

2019

Centenarians are individuals who live over the average life span characteristic of their population. The growing number of old people worldwide makes it necessary to identify a good strategy to reach healthy ageing and avoid or delay age-related diseases. The longevity phenotype is the result of a positive combination between genetic, epigenetic, stochastic and lifestyle factors. So, the analysis of all the known parameters that can influence these single elements or their interaction can give new possible elements to delineate a sort of longevity signature. Starting from the easiest biomarkers as the haematochemical values and reaching the study of molecular and cellular components, as the…

LONGEVITY AND THE SECRETS OF CENTENARIANS

2017

Aging of the world populations represents one of the most remarkable success stories of medicine and of humankind. Hence, the search for ways to prolong health expectancy is a primary goal in medicine. Human life expectancy increased extraordinarily during the last century worldwide. Life expectancy at birth has almost doubled in most developed countries over the last century, with the oldest group being the most rapidly growing segment of the population. The number of centenarians in Italy is over 16.000 and the number is over tripled in few years (they were 5.000 in 2001). Among older population, centenarians may be considered the best example of successful aging. The capacity to avoid, d…

Centenarians and diet: what they eat in the Western part of Sicily.

2012

Abstract This paper pays attention to the modifiable lifestyle factors such as diet and nutrition that might influence life extension and successful ageing. Previous data reported that in Sicily, the biggest Mediterranean island, there are some places where there is a high frequency of male centenarians with respect to the Italian average. The present data show that in Sicani Mountain zone there are more centenarians with respect to the Italian average. In fact, in five villages of Sicani Mountains, there were 19 people with an age range of 100–107 years old from a total population of 18,328 inhabitants. So, the centenarian number was 4.32-fold higher than the national average (10.37 vs. 2.…

Myocardial Infarction in Centenarians. Data from The Polish Registry of Acute Coronary Syndromes

2020

Background: There are no data regarding the mortality rate, risks and benefits of particular reperfusion methods and pharmacological treatment complications in patients aged over 100 years with acute coronary syndromes. We sought to assess the treatment of myocardial infarction (MI) in patients older than 100 years and to determine prognostic factors for this group. Methods: Among the 716,566 patients recorded between 2003 and 2018 in the Polish Registry of Acute Coronary Syndromes, 104 patients aged &ge
