Healthy Aging and Dietary Patterns.

A number of factors contribute to the complex process of aging, which finally define whether someone will or not develop age-associated chronic diseases in late life. These determinants comprise genetic susceptibility as well as various behavioral, environmental, and dietary factors, all of which have been shown to influence specific pathways regulating the aging process and the extension of life, which makes longevity a multidimensional phenomenon. Although a "miraculous elixir" or a "nutrition pill" are not plausible, researchers agree on the notion that nutritional factors have major impact on the risk of age-associated chronic non-communicable diseases and mortality. In recent years nutrition research in relation to health outcomes has considerably changed from focusing exclusively on single nutrients to considering combinations of foods rather than nutrients in isolation. Although research on specific nutrients is scientifically valid providing crucial evidence on the mechanisms by which nutrition impacts health, the recent switch targeting the multifaceted synergistic interplay among nutrients, other dietary constituents, and whole foods, has promoted emerging interest on the actions of total dietary patterns. This narrative review aims to describe some specific dietary patterns with evidence of associations with reduction in the incidence of chronic diseases allowing older adults to live a long-lasting and healthier life, and confirming the powerful impact nutrition can exert on healthy aging.

Benign pancreatic hyperenzymemia-Gullo's syndrome: focus on this clinical challenge. A monocentric retrospective study.

BACKGROUND: An abnormal and chronic rise of pancreatic enzymes in the blood is most often due to pancreatic diseases, primarily inflammatory or neoplastic, or to numerous extra-pancreatic pathologies. Benign chronic pancreatic hyperenzymemia was described for the first time - as a separate nosological entity - in 1996 by Lucio Gullo et al. They demonstrated the existence of a benign chronic pancreatic hyperenzymemia in asymptomatic subjects and without clinical implications; however, a follow-up of at least 1-2 years is necessary during which no specific symptomatology or morpho-functional impairment of the pancreas should occur, also evaluated through the aid of instrumental diagnostic investigations such as ultrasonography (US), computed tomography (CT) or magnetic resonance cholangio pancreatography (MRCP). METHODS: This study was performed with the analysis of a group of 43 subjects arrived at the observation of the Gastroenterology Team of Policlinico Hospital G. Rodolico in Catania-Italy which presented a chronic pancreatic hyperenzymemia, in order to establish the actual benignity of this condition over time. RESULTS: During the follow-up, pancreatic alterations and hyperenzymemia were found in 10 patients, while hyperenzymemia was not associated with pancreatic modification in 33 patients. CONCLUSIONS: Because of this enzymatic elevation - often conspicuous and lasting - the patient is often particularly anxious. For the same reason, the patient frequently undergoes very expensive laboratory and instrumental diagnostic methods. Good knowledge of the syndrome makes it possible to manage the event more rationally, also to reduce management costs to a minimum.
