- Background & aims Nutritional therapy has traditionally been evaluated by changes in weight and in food intake, while body composition and function may be of greater clinical significance. We investigated relationships between total body skeletal muscle mass (TBSMM), energy balance and exercise capacity in 41 patients before, 6 and 12 months after curatively intended major upper gastrointestinal surgery. Methods TBSMM and body energy content were assessed by DXA. Exercise capacity was measured on a treadmill. Energy balance was defined as the difference in body energy content at two points in time. Results During the first postoperative year average weight loss was 7% although 1 our of 3 patients remained weight stable (WS). Average TBSMM decreased significantly at 6 months (0.9 kg, p < 0.01), but was regained at 12 months, as was exercise capacity. 72% of weight losing patients (WL) lost TBSMM compared to 17% of WS patients, p < 0.01. Both TBSMM and changes in TBSMM, but not changes in energy content, were correlated to exercise capacity, r2 = 0.49, p < 0.001 and r2 = 0.15, p < 0.05 respectively. Conclusions TBSMM and exercise capacity were clearly related in cancer patients after major upper gastrointestinal surgery, as were changes in TBSMM and exercise capacity. Energy balance was not directly correlated to exercise capacity, but more WS than WL patients increased their TBSMM indicating a possible influence by energy balance.

- Dietary pattern analysis represents a useful improvement in the investigation of diet and health relationships. Particularly, the Mediterranean diet pattern has been associated with reduced mortality risk in several studies involving both younger and elderly population groups. In this research, relationships between dietary macronutrient composition, as well as the Mediterranean diet, and total mortality were assessed in 1,037 seventy-year-old subjects (540 females) information. Diet macronutrient composition was not associated with mortality, while a refined version of the modified Mediterranean diet index showed a significant inverse association (HR=0.93, 95% CI: 0.89; 0.98). As expected, inactive subjects, smokers and those with a higher waist circumference had a higher mortality, while a reduced risk characterized married and more educated people. Sensitivity analyses (which confirmed our results) consisted of: exclusion of one food group at a time in the Mediterranean diet index, exclusion of early deaths, censoring at fixed follow-up time, adjusting for activities of daily living and main cardiovascular risk factors including weight/waist circumference changes at follow up. In conclusion, we can reasonably state that a higher adherence to a Mediterranean diet pattern, especially by consuming wholegrain cereals, foods rich in polyunsaturated fatty acids, and a limited amount of alcohol, predicts increased longevity in the elderly.
