Cardiovascular risk during physical activity in the mountains.

Objective: Several previous studies evaluated the cardiovascular risk associated with exercise, but only a few papers considered this risk during physical activity in the mountains. The aim of this study was to assess the cardiovascular risk in a population practising physical activity in the mountains.

Methods: We used an observational study design.

Metabolic and cardiovascular parameters in type 1 diabetes at extreme altitude.

Purpose: The American Diabetes Association states that physical activity can be performed by individuals with Type 1 diabetes. Nevertheless, extreme altitude mountaineering represents a demanding challenge. We present the metabolic and cardiovascular parameters found in individuals with Type 1 diabetes during the ascent to Cho Oyu located at a height of 8201 m.

Cancer mortality trends in two cohorts of elderly people having different life-styles.

We analyzed cancer mortality trends in 3282 elderly subjects from two general Italian populations with different life-style patterns taking part in the Cardiovascular Study in the Elderly (CASTEL). The aim of the study was to evaluate which predictors were able to influence cancer mortality. Age, gender, tobacco smoking, the presence of respiratory symptoms, increased serum levels of ALT and ALP, and the town of residence were powerful predictors.

24-hour leg and forearm haemodynamics in transected spinal cord subjects.

Objective: A circadian rhythm of blood pressure has been demonstrated both in subjects who are physically active during the day and in those confined to bed. The study of the circadian rhythm of arterial flow and peripheral resistance, on the other hand, is limited to pioneer experiments. This paper is aimed at demonstrating that leg peripheral resistance has circadian fluctuations which are modulated by spinal neural traffic.
