RESUMEN
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.
RESUMEN
Twenty-five subjects with no pelvic floor dysfunctions at defecography were examined with direct coronal CT scans of the pelvis at rest and on straining. Three compartments with different characteristics were delimited by two planes-the anterior one being tangent to the ischiatic foramen and the posterior one to the ischial tuberosities. At rest, the average length of the levator ani muscle and the surface of the supralevator space were significantly lower posteriorly than in the other two compartments (48.3 mm +/- 7.9; 48.8 mm +/- 7; 42.6 mm +/- 9.4, p < 0.05 and 70.6 cm2 +/- 7.5; 66.9 cm2 +/- 11.2; 27.2 cm2 +/- 4.8, p < 0.01, respectively). On straining, maximum muscle lengthening occurred posteriorly, as indicated by similar average values (63.7 mm +/- 12.7; 63.3 mm +/- 9.5 and 60.5 mm +/- 14) and the corresponding increase (+12.5%) in the supralevator space occurred in the middle compartment (73.8 cm2 +/- 7.6; 75.3 cm2 +/- 11.6 and 30.2 cm2 +/- 5.2). To conclude, our method proved reliable enough (intra- and interobserver correlation index > 80%) and promising for future clinical applications and studies of pelvic floor dysfunctions.
