Does the Multidimensional Prognostic Index (MPI), based on a Comprehensive Geriatric Assessment (CGA), predict mortality in cancer patients? Results of a prospective observational trial.

OBJECTIVE: Despite the lack of definitive data on the impact of Comprehensive Geriatric Assessment (CGA) in the geriatric oncology setting, the broad use of any form of CGA is strongly recommended before any treatment decision in elderly cancer patients (ECP); currently there is no consensus about the best format for this geriatric assessment. The aim of this study was to firstly test the Multidimensional Prognostic Index (MPI) in ECP with locally advanced or metastatic disease. MATERIALS AND METHODS: Patients aged ≥70years with inoperable or metastatic solid cancer consecutively admitted to our Program of Geriatric Oncology were assessed by a multidisciplinary team and received a basal CGA to calculate the MPI score. RESULTS: A hundred and sixty patients entered the study. In the Cox's regression model, MPI, CIRS-SI, BSA, GDS, MMSE, chemotherapy and a diagnosis of primary lung cancer were associated with mortality at 6 and 12months. The ROC curves confirmed the prognostic value of MPI, with the best discriminatory power for mortality at both 6 and 12months. CONCLUSION: The present study is the first to indicate that the MPI retains its prognostic value even in elderly cancer patients with advanced stage of disease. The CIRS-SI and the GDS may potentiate the prognostic value of MPI.

Quantitative ultrasound criteria for risk stratification in clinical practice: a comparative assessment.

This study aimed to compare two different classifications of the risk of fracture/osteoporosis (OP) based on quantitative ultrasound (QUS). Analyses were based on data from the Epidemiological Study on the Prevalence of Osteoporosis, a cross-sectional study conducted in 2000 aimed at assessing the risk of OP in a representative sample of the Italian population. Subjects were classified into 5 groups considering the cross-classification found in previous studies; logistic regression models were defined separately for women and men to study the fracture risk attributable to groups defined by the cross-classification, adjusting for traditional risk factors. Eight-thousand six-hundred eighty-one subjects were considered in the analyses. Logistic regression models revealed that the two classifications seem to be able to identify a common core of individuals at low and at high risk of fractures, and the importance of a multidimensional assessment in older patients to evaluate clinical risk factors together with a simple, inexpensive, radiation-free device such as QUS.

Tooth loss in the elderly and its association with nutritional status, socio-economic and lifestyle factors.

OBJECTIVE: Tooth loss impacts on general health and is a risk factor for malnutrition, disability, loss of self-sufficiency, and deterioration in quality of life. The present study was carried out to evaluate the prevalence of edentulism and its association with social and lifestyle factors in a population of elderly Italians. MATERIAL AND METHODS: Dental, social, and disease conditions were evaluated in a large community-based cohort (3054) of elderly subjects (> or =65 years) of both sexes in northern Italy. Logistic regression analyses with stepwise forward selection were performed to estimate the independent contribution of nutritional, socio-economic, and lifestyle variables to dental status. Adjusted ORs and 95% CI were estimated for variables significantly associated with edentulism. RESULTS: The prevalence of edentulism was about 44.0%. It was more pronounced in females and it was twice as prevalent in the 90+ years age group. Among edentulous subjects, 17.5% wore no prostheses. Difficulties in chewing and in swallowing were reported by 47.6% and 13.7% of the subjects, respectively. Multivariate analysis indicates that edentulism was associated with age in both sexes. For women, independently associated risk factors were: years since menopause >23 (OR = 1.81; 95% CI: 1.37-2.40), number of children >3 (OR = 1.95; 95% CI: 1.36-2.80), and living alone (OR = 1.47; 95% CI: 1.15-1.88). For men, these were serum albumin <40 g/l (OR = 1.79; 95% CI: 1.22-2.63), current smoking (OR = 4.01; 95% CI: 2.59-6.20), and former smoking (OR = 3.42; 95% CI: 2.42-4.82). CONCLUSIONS: The prevalence of edentulism among the elderly Italian population studied was at the high end among Western countries, and higher in women than in men. In women, tooth loss correlated with aging, female events (pregnancies, menopausal status), and living alone. In men, aging and smoking are important determinants of edentulism, which is associated with the risk condition of hypoalbuminemia. Difficulty in chewing was associated with dentition type. In our study, the high prevalence of edentulous subjects without prostheses suggests a need for educational and social measures to improve patients' attitudes to dental care and to encourage the use of prostheses among the elderly.

Predictors of transitions in vitality: the italian longitudinal study on aging.

It is widely acknowledged that there is a strong need to identify which modifiable risk factors predict healthy aging to use this information as the scientific basis for systematic interventions. Data from a 4-year longitudinal study on aging among 5632 older Italians were used. The definition of vitality was based on both cognitive and physical status, and the envisaged transitions were: positive or nonpositive stable, positive or negative transition, lost, and deceased. Predictors associated with different vitality trajectories were investigated by multinomial logistic analysis with a six-level outcome. Age and educational level were predictors of being "positive stable," whereas the other factors behaved differently according to comparison group. For example, being overweight is a common predictor except when compared to the deceased group, as is depressive symptomatology except when compared to the "positive transition" group. Interventions are warranted to reduce social inequalities, promote adequate body weight, and prevent and treat depressive symptoms.
