Non smoking for successful aging: therapeutic perspectives.

The smoke of cigarettes represents an important accelerator of the aging process, and there is no doubt that smoke is an important risk factor for many diseases, in particular for cardiovascular, neoplastic and respiratory diseases. Smoking plays an important role also in the development of other pathological conditions being particularly frequent in geriatric ages, such as dementia, osteoporosis, diabetes, erectile dysfunction, senile macular degeneration, nuclear cataract and alterations of skin. This means that smoke compromises not only life expectancy, but also the quality of the life, favoring the occurrence of non-autonomy.

Is interleukin-22 a possible indicator of chronic heart failure's progression?

Chronic heart failure (CHF) is a complex and heterogeneous clinical syndrome and because of its rising incidence and prevalence, it can be considered a global epidemic. Interleukin (IL)-22 is a pro-inflammatory cytokine, belonging to the IL-10 family. Forty-seven consecutive older patients, hospitalized with an admitting diagnosis of CHF at the Geriatric Medicine Unit (University of Messina, Italy), from 01/01/06 to 30/06/06, were enrolled in the study.

Smoking, health and ageing.

On March 19, 2008 a Symposium on Pathophysiology of Ageing and Age-Related diseases was held in Palermo, Italy. Here, the lecture of V. Nicita-Mauro on Smoking, health and ageing is summarized.

Smoking, aging and the centenarians.

The smoke of cigarettes represents an important accelerator of the aging process, both directly through complex mechanisms mediated prevalently by excessive formation of free radicals, and indirectly by favoring the appearance of various pathologies in which smoke is a recognized risk factor. This means that smoke compromises not only life expectancy, but also the quality of the life, favoring the occurrence of non-autosufficiency. Smoking is an important risk factor for many diseases, such as cancer, cardiovascular and respiratory diseases.

Vascular aging and geriatric patient.

Advancing age is associated with changes in structure and function of different segments of the vascular system and is the dominant risk factor for cardiovascular diseases. The oxidative stress represents a key event of vascular aging, mainly characterized by endothelium dysfunction and reduced arterial elasticity. Age-related changes include intimal and medial thickening, arterial calcification, increased deposition of matrix substances, thus leading to a reduced compliance and increased wall stiffness, that significantly contributes to an increase in systolic blood pressure.
