Nonagenarians are a fast-growing population deserving specific research. We explored the prevalence and characteristics of functionally independent nonagenarians from a rural community-dwelling Italian population. Data were collected in the Mugello Study; 475 persons aged ≥90 years (median age, 92) underwent a home-based clinical and functional assessment, including psychosocial, clinical, functional, and lifestyle history and status and physical and instrumental examinations. Sixty-eight (15%) persons reported no need for help in basic and instrumental daily living activities. Among variables significantly associated with independent functionality after age- and gender-adjusted cross-sectional analysis, lower body mass index (BMI; p =.034) and depressive symptoms (p =.028), higher current physical activity (p <.001), better cognitive status (p =.033), and lower medication intake (p =.048) were associated with reporting no disability in the logistic regression analysis. Disability was mainly associated with current lifestyle-related potentially modifiable factors. Thus, lifestyle-oriented multidimensional interventions, should be developed and evaluated for their potential effects on functionality, even in the oldest old. [ABSTRACT FROM AUTHOR]

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.

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]

The evolution to bipedalism forced humans to develop suitable strategies for dynamically controlling their balance, ensuring stability, and preventing falling. The natural aging process and traumatic events such as lower-limb loss can alter the human ability to control stability significantly increasing the risk of fall and reducing the overall autonomy. Accordingly, there is an urgent need, from both end-users and society, for novel solutions that can counteract the lack of balance, thus preventing falls among older and fragile citizens. In this study, we show a novel ecological approach relying on a wearable robotic device (the Active Pelvis Orthosis, APO) aimed at facilitating balance recovery after unexpected slippages. Specifically, if the APO detects signs of balance loss, then it supplies counteracting torques at the hips to assist balance recovery. Experimental tests conducted on eight elderly persons and two transfemoral amputees revealed that stability against falls improved due to the 'assisting when needed' behavior of the APO. Interestingly, our approach required a very limited personalization for each subject, and this makes it promising for real-life applications. Our findings demonstrate the potential of closed-loop controlled wearable robots to assist elderly and disabled subjects and to improve their quality of life. [ABSTRACT FROM AUTHOR]
