ABSTRACT
Among lifestyle factors, nutrition is one of the most important determinants of health, and represents a pivotal element of cancer risk. Nonetheless, epidemiological evidences of the relationship between several cancers and specific foods and nutrients is still inadequate, and solid conclusions are missing. Indeed, caloric restriction without malnutrition is associated to cancer prevention. Food may be also the primary route of exposure to contaminants such as metals, persistent organic pollutants, and pesticides. Exposuredisease associations and the interplay with genetic susceptibility requires further studies on genetic variation, environment, lifestyle, and chronic disease in order to eliminate and reduce associated health risks, thus contributing to improve health outcomes for the population. A primary nutritional approach for Active and Healthy Ageing (AHA) has been developed by the Nutrition group of the European Innovation Partnership (EIP) on AHA. The working group on lifestyles of the Italian Ministry of Health has developed a comprehensive approach to adequate nutrition using a consensus methodology to collect and integrate the available evidences from the literature and from the Italian experiences at the regional level, to raise the interest of other experts and relevant stakeholders to outline and scale-up joint strategies for a primary nutritional approach to cancer prevention.
ABSTRACT
INTRODUCTION: In Italy, Tubercolosis (TB) has increasingly become a disease for specific population subgroups such as immigrants. The objective of this paper is to describe the trend in TB incidence from 1999 to 2008 in Umbria: a low-incidence Italian region with high immigrants rates. METHODS: Data were obtained from the Regional Information System for Infectious Diseases. Using a linear regressions model we estimated trends for number of cases and incidence rates; with a logistic regression model we estimated the effect of a set of covariates on the probability of being affected by TB. RESULT: 590 TB cases were reported of whom 254 (43%) were foreign. In 2008 39.7 new cases per 100.000 were registered among foreign-born subjects. TB incidence among Italians was 3.8/100.000 Italians. But a linear regression analysis showed a statistically significant decreasing trend in the notification rate among foreign-born people (coef: -7.32, r2:0.57, p < 0.05). The probability to be affected by extra-pulmonary is significantly larger in foreign patients (OR = 0.72, CI = 0.48-1.07). Foreign unskilled workers report a higher probability to be affected by TB (OR = 19.05, CI = 6.01-60.4). DISCUSSION: Increasing immigration rates may affect TB epidemiology. The analysis of incidence trends is an important toolfor monitoring tuberculosis disease control and to identify specific sub-group at risk.

We have undertaken the present study to evaluate the acute effects of propranolol and verapamil on the diastolic function in patients with hypertrophic cardiomyopathy. We used a non imaging isotope device, the nuclear stethoscope, that has been so far mainly employed for assessment of systolic function, although fitted for detecting diastolic filling rates and times as well. Relative cardiac output, ejection fraction, rapid and slow filling times and rates were measured in five patients suffering from hypertrophic cardiomyopathy in basal conditions and 10.20 and 30 minutes after i.v. administration for either propranolol or verapamil, with a time interval of at least 24 hours between the two acute drug studies. With respect to the baseline values only verapamil showed a significant improvement in rapid and maximum filling rates, suggesting that diastolic function is more beneficially affected by Ca-entry blockers rather than beta-blockers in hypertrophic cardiomyopathy.
