Evaluation of the cardiovascular health study (CHS) instrument and the Vulnerable Elders Survey-13 (VES-13) in elderly cancer patients. Are we still missing the right screening tool?

BACKGROUND: A geriatric screening tool would be valuable to identify elderly cancer patients who might benefit from a comprehensive geriatric assessment (CGA). This study evaluated the accuracy of the cardiovascular health study (CHS) instrument in predicting abnormality in CGA. The vulnerable elders' survey-13 (VES-13) was also evaluated. PATIENTS AND METHODS: Patients aged ≥ 70 years with solid tumors underwent a CGA after being screened with the CHS and VES-13. Analyses were conducted for the overall population and according to the disease status (early or advanced) and type of early cancer (breast or gastrointestinal, GI). RESULTS: Of 259 patients, 75% were impaired according to the CHS and 47% according to the VES-13. CGA impairment was reported in 171 patients (66%). In the overall population, overall accuracy, sensitivity and specificity of CHS in identifying CGA impairments were 74%, 87% and 49%, respectively. The corresponding figures for the VES-13 were 68%, 62% and 81%. Sensitivity and specificity of CHS in predicting CGA impairments in subgroups were early 81% and 55%, advanced 98% and 29%; early breast 78% and 69%, early GI 87.5% and 19%. CONCLUSIONS: The CHS compared favourably with VES-13 for sensitivity. However, the great variability in specificity observed with the CHS within subgroups limits its applicability in the global population.

Physical performance and creative activities of centenarians.

The human functional autonomy is reduced progressively with advancing age, although a considerable proportion of the centenarians maintain a good level of autosufficiency for the basic performance of the everyday life. Even if males have a lower probability to reach the centenarian age than females do, the male centenarians display generally better functional conditions than the females. Actually, there are no systemic studies on centenarian works or activities; nevertheless, the examples of several representative persons (artists, scientists, explorers, etc.) who remained active even after this age indicate that such a possibility is realistic, and that the maintenance of vital interest and passions, thus preserving competence and professional attitudes, is not in conflict with the reaching of extreme longevity.

Cognitive and functional status in the extreme longevity.

Usually, the effects of cognitive decline are not noted before the age of 70 years, which involve the intellectual capacities, the attention, the processes of elaboration and the memory. The studies on the cognitive disturbances of the elderly are numerous, and document the progressive increase of cerebral deterioration with advancing age. However, only a few studies refer to the significance of the cognitive disturbances in the clinical conditions and autonomy of the long living subjects. For this reason, we studied the cerebral deterioration of an adequate number of centenarians in correlation with their clinical conditions and autonomy. Our centenarian sample derived from the Italian multi-center study on centenarians (IMUSCE), which was an epidemiological study which identified 1173 centenarians (202 males, 971 females) in the age range of 100-109 years. From this sample, we analyzed 346 subjects as far as the cognitive functions and the degree of autonomy by using the psychometric tests of the mini-mental state examination (MMSE) and the instrumental activities of daily living (IADL) for the functional evaluations. In addition, we evaluated the clinical conditions of the subjects dividing them in three groups: Group A (those in good clinical conditions), Group B (those in discrete clinical conditions), and Group C (those in deteriorated clinical conditions). These analyses revealed that 187 (54.1%) of the 346 examined centenarians have shown an MMSE score in the normal range (score ratio from 1.0 to 0.63). The cognitive disorders are present in the centenarians in a clearly higher frequency (13.1%), than found in the common elderly (5.1%). The severe cognitive disorders do not allow a total autonomy or even a slight dependency. Only six subjects (1.7%) of the total sample were totally independent. These subjects had no cognitive disorders, and were in good clinical conditions. The results show that having an MMSE score in the normal range, and being in good clinical conditions are necessary but not sufficient prerequisites for a total autonomy in the IADL scores.

Longevity index (LI%) and centenarity index (CI%): new indicators to evaluate the characteristics of aging process in the Italian population.

Centenarians represent a group of population displaying the most rapid expansion. This progressive increase of the presence of centenarians is a multi-factorial phenomenon, which is due to the improvements of the environmental conditions and the life style and also to the progress of the medical science. In order to obtain a more reliable estimate of the longevity per gender and territorial entities, we propose two new indicators. (i) The ratio between the ultranonagenarians and the total population above 65 years old (called longevity index: LI%); (ii) the ratio between the centenarians and the total population above 90 years old (called centenarity index: CI%). An analysis of the data of the Italian National Office of Statistics (ISTAT, ) using these two indicators demonstrates that the subjects above the age of 90 are more frequent in the regions of Central and Northern Italy, which are more developed regarding the economic conditions and technological progress. Nevertheless, the Southern and Insular regions of Italy have a higher occurrence of centenarians among the ultranonagenarian population, and also a higher prevalence of male centenarians, as compared to the northern regions. This demonstrates that achievement of the threshold of 100 years old does not require only particular socio-economic conditions, but also an adequate climate and environment, as well as a favorable genetic composition.

Red or white wine assumption and serum antioxidant capacity.

The biochemistry of reactive oxygen species is an important field with wide implications. Both preventive and chain breaking antioxidants have a role in the limitation of oxidative stress that accompanies aging and diseases. The potent antioxidant activity of phenolic substances of red wine, in particular, have been proposed as an explanation for the "French Paradox" (the apparent incompatibility of a high fat diet with a low incidence of coronary heart diseases). A lot of researchers emphasize beneficial effects of red wine and insist on lower or no antioxidant effect of white wine. We have been studying the effect of both white and red wine on blood antioxidant capacity in humans. The white wine we have been testing was produced by an ancient Tuscany procedure (the same used for red winemaking) which includes fermentation with grapes juice together with peelings and seeds. A statistically significant increase in total antioxidant capacity (TAC) levels was observed after 2h from red or white wine ingestion. White wine effect appears to be faster than that of the red one, since a significant difference can also be reported after 1h. We can conclude that the big difference in the results of serum TAC due to white wine reported by us, in comparison to those reported by others relatively to white wine produced using the French method, can be explained by the difference in the winemaking procedure we adopted.

Centenarians in Tuscany: The role of the environmental factors.

Statistical data of Italy, issued on 1st January 2005, show that Tuscany has a high percentage of elderly subjects, and that to reach 100 years is a common possibility, mainly for women. Comparable values appear for longevity index (LI%), either calculated on the basis of the various resorts above sea level, or on the basis of the number of inhabitants. However, some differences are observed considering the various provinces: Grosseto Province has the second higher value of >65-year-old subjects, while its LI% is the lowest. Centenarity index (CI%) considerably differs from LI%: if ranking Tuscany according to the various heights of territorial positions, the first displays a negative, while the second one shows a positive correlation with the local height. If comparing for inhabitants number, CI% is maximal in provincial cities, while LI% is higher in smaller communities. All these data indicate that residents in small communities of the mountains reach easily 90 years, while 100 years are more frequently reached in larger cities in the plane areas. In conclusion, the highest province longevity (Lucca) coincides with the highest centenarian sex ratio, and it suggests that in this province the older women may enjoy particular forms of environmental protection, which helps them for reaching 100 years of age. Differences between the results of this study and others performed in Sardinia are discussed.
