Background and Aim: Adherence to the Mediterranean Diet (MD) has been associated with a longer and better life. The aim of this study was to examine the effects of adherence to the MD, and of nutritional habits on endothelial progenitor (EPCs) and circulating progenitor (CPCs) cells in a cohort of nonagenarians enrolled within the Mugello Study, an epidemiological study aimed at investigating both clinically relevant geriatric items and various health issues, including those related to nutritional status.Methods and Results: Four hundred twenty-one nonagenarians (306 F, 115 M, mean age: 93.1 ± 3.2 years) were evaluated. Adherence to MD was assessed through the Mediterranean Diet Score. Elderly subjects who were in the fourth quartile of the Mediterranean diet score showed significantly higher EPCs than subjects grouped into the other three quartiles. After adjustment for confounders, elderly subjects who were in the highest quartile of adherence to the MD score reported to have EPCs' levels significantly higher than those who reported lower values of adherence to the MD. Furthermore, by analyzing different food categories, it was reported that daily consumption of olive oil and a higher consumption of fruit and vegetables showed higher CPCs CD34+ and EPCs CD34+/KDR+ than subjects with not daily or lower consumption.Conclusion: Our results support the hypothesis that the adherence to MD, as well as a daily consumption of olive oil and fruit and vegetables, characteristics of MD, may protect against the development of endothelial dysfunction through increasing EPCs and CPCs in older age.

Abstract: Background and aims: Whether uric acid (UA) serves as risk factor for cardiovascular diseases or as antioxidant defense has not yet been completely clarified. In this study we investigated the effects of UA on functional recovery in patients receiving cardiac rehabilitation. Methods and results: 306 patients, 209 men and 97 women, age range 25–87 years (mean 68 ± 11), performed the 6-min walk test (6mWT) before and after the rehabilitation, and the increase in walking distance was considered as the outcome measure of the study. Baseline UA serum levels ranged from 1.0 to 10.9 mg/dL (mean 5.2 ± 1.7). As there was a significant (p = 0.005) age*UA levels interaction, patients were divided into two subgroups, less then 65 years (n. 103, 68 men and 35 women, mean age 56 ± 9) and 65 years or more (n. 203, 141 men and 62 women, mean age 74 ± 5). After adjusting for relevant confounders, higher UA levels remained independent positive predictors of the increase in walking distance in older (p < 0.001) but not in younger patients (p = 0.807). Conclusions: Our findings show an independent association of higher UA levels with better functional recovery after cardiac rehabilitation selectively in elderly patients, suggesting that higher UA levels might reflect the decline in antioxidant defenses that occurs with advancing age. Future studies aimed at understanding the several contradictions concerning UA should, probably, address the issue within this perspective. [Copyright &y& Elsevier]

Abstract: Background and Aim: Previous studies have shown that increased levels of C-reactive protein (CRP) predict cardiovascular events, including stroke, myocardial infarction and death from cardiovascular causes. Previous studies have also shown that increased levels of CRP are strong predictors of the progression of pre-existing carotid artery plaques. However, whether CRP is involved in the development of new plaques, that may or may not be associated with clinical events, in subjects with clean carotid arteries has been scarcely investigated. Methods and Results: 486 “InCHIANTI” Study participants (200 men and 286 women, 72% aged 65 years and over) free from carotid artery plaques at baseline, also underwent carotid artery scan three years later. We tested the association of baseline characteristics, cardiovascular risk factors and inflammatory markers with the development of new carotid artery plaques. Older participants were significantly more likely to develop new plaques. Independent of age, the relative risks of developing new plaques associated with heavy smoking and family history of atherosclerosis were 1.7 (95%CI 1.5–1.9) and 1.9 (95%CI 1.2–3.1), respectively. Participants with high (>3 μg/mL) and moderate (≥1 and ≤3 μg/mL) CRP levels had a relative risk of 2.2 (95%CI 1.9–2.6) and 1.9 (95%CI 1.6–2.3) respectively, when compared with subjects with low (<1 μg/mL) CRP levels. Surprisingly, risk factors such as hypertension, diabetes, dyslipidemia and overweight/obesity were not significant predictors of the development of new carotid artery plaques. Conclusions: High CRP levels independently predict the development of new plaques in older persons with carotid arteries free from atherosclerotic lesions. [Copyright &y& Elsevier]

BACKGROUND AND AIMS: Physical activity in older adults improves fitness, but few studies have examined the short- and long-term effects on physical performance. This analysis is preliminary to a RCT investigating physical activity effects on performance over time in older persons with musculoskeletal impairment. METHODS: Fifty sedentary participants, aged 65+, with musculoskeletal impairment and difficulties in complex mobility, but independent in basic activities of daily living (ADLs) were randomly assigned to 3- monthly, twice-a-week, supervised physical exercise (E) or unsupervised regular walking (W), and advised to keep active. Assessments: baseline (T0), discharge (T1), 6 (T2) and 9 (T3) months from baseline. Outcome: Summary of Performance Score (SPS), strength, flexibility; general mental health (GMH), vitality, and selfreported disability. RESULTS: All participants completed follow-ups. At T3, only 12 E and 2 W participants reported exercising regularly. Each outcome, except for GMH, trunk flexibility and basic ADLs, changed over time significantly more in E than in W. After training, E increased SPS (1 point), along with muscle strength, flexibility, vitality, and reduced difficulties in complex mobility. At 9 months, all parameters, except passive hip flexion and shoulder abduction, had reverted to baseline levels. In the same time-frame, W progressively decreased SPS, knee flexion/ extension strength and passive flexion, and increased difficulties in basic and complex mobility. CONCLUSIONS: In this physically impaired sample, a 3- month exercise program, compared with unsupervised regular walking, was associated with improved performance, fitness and vitality after discharge, and to delayed physical decline in the next 6-month follow-up.

Summary: Objective: To describe prevalence, characteristics and correlates of hip pain (HP) and knee pain (KP) in an Italian community based cohort aged 65 and older (65+). Method: Baseline survey (1998–2000), population-based study in the Chianti area (Tuscany, Italy); 1299 persons aged 65+ were selected from the city registry of Greve in Chianti and Bagno a Ripoli (multistage sampling method); 1006 participants (564 women and 442 men, age 75.2±7.1) provided information for this analysis. Persons reporting HP/KP in the past 4 weeks were recorded and their Western Ontario and McMaster University Osteoarthritis Index pain score (WPS-range 0–20) calculated. Potential correlates of HP/KP, including clinical, lifestyle and psycho-social features and physical measures, were tested in age- and gender-adjusted regression analyses and then entered a multivariate regression model. Results: HP was reported by 11.9% participants, while 22.4% reported KP and 7.2% both conditions. Climbing/descending stairs and walking were the activities eliciting more severe pain in either condition. Average WPSs were 5.6±3.5 for HP and 5.4±10.4 for KP. Both HP and KP were related to back pain, reduced hip abduction, reduced muscle power and increased trunk flexibility. HP was also related to KP and poor self-rated health (SRH), while KP to HP, foot pain, high body mass index, reduced knee passive flexion and knee extension torque, low education. Conclusion: In a community sample of an Italian persons aged 65+, the prevalence of KP almost doubled that of HP. While both conditions were related to pain in other joints and specific joint impairment, only HP was related to poor SRH, and only KP to mechanical overload. [Copyright &y& Elsevier]

Abstract: Background and aims: Nutritional therapy is a cornerstone of the treatment of type 2 diabetes. The aim of this study was to assess differences in dietary habits between subjects with and without known type 2 diabetes. Methods and Results: In a sample of 1242 predominantly elderly subjects enrolled in the InCHIANTI study, total energy and macronutrient intake was assessed cross-sectionally using the EPIC self-reported questionnaire. Results were compared in subjects with (N =109) and without known diabetes, and differences were adjusted for age, sex, and reported comorbidities. Subjects with known diabetes reported a significantly lower (p <0.001) total energy and soluble carbohydrate intake in comparison with the rest of the sample (1793±481 vs 2040±624kCal/day, and 66.9±22.3 vs. 93.5±34.9g/day, respectively). Conversely, consumption of total and saturated fats, dietary fibres and proteins was not significantly different. Conclusion: Known diabetes is associated with a reduction of soluble carbohydrate consumption and total energy intake without any further modification of dietary habits. These data suggest that the diagnosis of diabetes could induce some changes in nutritional style. However, corrections in dietary habits do not appear to be consistent with current guidelines and recommendations. [Copyright &y& Elsevier]
