RESUMEN
BACKGROUND: Traditional risk factors used to assess cardiovascular risk miss a significant population who are indeed at risk for future cardiac events. Erectile dysfunction (ED) is an emerging marker for future cardiovascular disease (CVD) and major adverse cardiovascular events (MACE), especially in young and middle-aged men with vasculogenic ED. Cavernous arteries morphological alterations at penile colour doppler ultrasound (P-CDU) are used to find a vasculogenic ED. OBJECTIVES: We investigated the possible relationship between cavernous arteries morphological alterations at P-CDU assessment and future MACE. MATERIALS AND METHODS: We conducted a retrospective cohort study involving 300 ED patients, aged 35-65 years (mean age 54.1 ± 7.1), with a follow-up period of 10 years. Patients underwent vascular evaluation including P-CDU, colour doppler ultrasound of the carotid and lower limbs arteries. At baseline data for glucose metabolism, lipid profile, hypertension and hormonal status were collected. During the follow-up period, the occurrence of MACE was evaluated. RESULTS: We found a strong association between cavernous arteries morphological alterations and CVD with a threefold increased risk of future MACE in comparison to patients with healthy cavernous arteries (RR 3.2, 95% CI 1.17-8.78). This association remained statistically significant after adjustment for CV risk factors (age, glycaemia, total cholesterol, hypertension and smoke). CONCLUSIONS: Morphological alterations of cavernous arteries are independently associated with an increased risk of future MACE. These data contribute to the formulation of the hypothesis that cavernous artery pathology at P-CDU is related to MACE.

BACKGROUND: The severe burden imposed by frailty and disability in old age is a major challenge for healthcare systems in low- and middle-income countries alike. The current study aimed to provide estimates of the prevalence of frailty and disability in older adult populations and to examine their relationship with socioeconomic factors in six countries. METHODS: Focusing on adults aged 50+ years, a frailty index was constructed as the proportion of deficits in 40 variables, and disability was assessed using the World Health Organization Disability Assessment Schedule (WHODAS 2.0), as part of the Study on global AGEing and adult health (SAGE) Wave 1 in China, Ghana, India, Mexico, Russia and South Africa. RESULTS: This study included a total of 34,123 respondents. China had the lowest percentages of older adults with frailty (13.1%) and with disability (69.6%), whereas India had the highest percentages (55.5% and 93.3%, respectively). Both frailty and disability increased with age for all countries, and were more frequent in women, although the sex gap varied across countries. Lower levels of both frailty and disability were observed at higher levels of education and wealth. Both education and income were protective factors for frailty and disability in China, India and Russia, whereas only income was protective in Mexico, and only education in South Africa. CONCLUSIONS: Age-related frailty and disability are increasing concerns for older adult populations in low- and middle-income countries. The results indicate that lower levels of frailty and disability can be achieved for older people, and the study highlights the need for targeted preventive approaches and support programs.

Background: Later years of life are accompanied by many physical; emotional and environmental changes which may impact on the well-being of the individual. Many factors are known to influence the subjective well-being of older adults; but most; if not all of this information was the result of studies in the Western world. This study aimed at obtaining and documenting the predictors of subjective well-being (SWB) among older Ghanaians. Methods: Data for the study was obtained from the WHO SAGE study. The single item measure of life satisfaction was used to determine subjective wellbeing. Descriptive statistics as well as logistic regression analysis were carried out to determine the predictors of SWB. Results: A total of 4724 individuals aged 50 years and above responded to the questionnaires. Of these 50.4 were males. Following multivariate logistic regression analysis; age; sex; educational level; income and ethnic background were found to significantly affect the SWB of older Ghanaians. Being male was associated with higher level of SWB (OR=1.68; CI: 1.39 - 2.03). For those 50 years and above; being younger (50-59 years) was also associated with a high level of SWB (OR=17.72; CI: 10.13-30.98). Earning a low income and having low educational level were both associated with low levels of SWB (OR=0.304; CI: 0.22-0.42; and OR=0.47; CI: 0.37-0.60 respectively). Ewes (p=0.027); Grumas (p=0.002) and Mole-Dagbons (p=0.04) had significantly higher SWB compared to the other ethnic groups. Conclusion: Among older Ghanaians; factors that positively influence SWB are younger age; male sex; high educational level and high income

OBJECTIVE: To explore the trends of vitamin intake over a 10-year follow-up in a group of successfully aging elderly people. DESIGN: Longitudinal study. SETTING: City of Padua, Italy. PARTICIPANTS: 78 (34M/44F) free-living and still well-functioning survivors among the Italian participants in the SENECA multicenter project, aged 70-75 y at the baseline. MEASUREMENTS: data were collected by means of a modified validated dietary history, both at baseline and then 10 y later. The dietary intake of vitamins B1, B2, A and C were considered, calculating the percentages of individuals with an intake below the lowest European Recommended Dietary Intake (RDI). RESULTS: mean energy and macronutrient intake were consistent with dietary guidelines at both time points. There was no decline in total energy intake after a decade. At baseline, the intake of all vitamins exceeded the Lowest European RDI, with the exception of vitamin B1, for which 44% of the men and 60% of the women were already deficient. After a decade, the prevalence of vitamin B2 and vitamin A deficiencies rose to 50% of the sample. Vitamin C deficiencies rose in a decade from 3% to 6% in men and from 2.3% to 4.5% in women and it was the least prevalent. CONCLUSION: despite an adequate nutritional/functional status and a total energy intake that could be expected to cover the recommendations for micronutrients too, a considerable proportion of our successfully aging elderly were already deficient in, or at high risk of becoming deficient in several essential vitamins. Multivitamin supplementation may be necessary, even in healthy individuals, to ensure an adequate micronutrient intake in the elderly.

AIM: The DALY measure represents a new tool for improving the capacity of local health unit to assess population health needs and priorities. Our study aimed to increase the validity of the Disability Adjusted Life Years (DALY), by incorporating local estimates of the disease incidence and applying population-specific disability weights. METHODS: This is a prospective cohort study enrolling subjects aged 45+ years, first-time admitted to the hospital with principal diagnosis of 490-492, 496 ICD IX-CM codes and followed for one year to evaluate the vital status. A subset was administered the Saint George Respiratory Questionnaire to estimate the distribution of the chronic obstructive pulmonary disease (COPD)-related disability. RESULTS: Estimates of total DALY (per 1000) for COPD varied between 2.1 to 3.4 years among men and between 1.0 to 2.3 years among women; percentages of years of life lost due to a premature mortality were between 60 and 70%. CONCLUSION: The DALY represents a new tool for improving the capacity to assess population health needs and priorities. Policy makers owning such a further element of evaluation may be better oriented in allocating resources for COPD among the different health care chapters: prevention, emergency, chronicity and rehabilitation.

OBJECTIVE: To explore the trends of food preferences and nutrient intake over a 10-year follow-up in a group of successfully aging elderly. DESIGN: Longitudinal study. SETTING: City of Padua, Italy. PARTICIPANTS: Randomly stratified sample of 97 men and 94 women born between 1913 and 1918. MEASUREMENTS: The study involved a dietary assessment conducted in 1988/89 and repeated in 1999. Data were collected by means of a modified validated dietary history. RESULTS: Nutrient and energy intake remained fairly stable over a decade, despite changes in eating habits, with a higher intake of sweets and a lower consumption of soft drinks in both genders. All individuals significantly increased their daily intake of water. CONCLUSION: Despite changes in eating habits, no significant decline in total energy and macronutrient intake was recorded in a decade in our elderly. The increased daily consumption of water and decreased use of soft drinks would suggest that these people were still receptive to nutritional advice even in very old age, while the increase in their sweet-eating might be because aging itself increases a person's sweet tooth, and this could be regarded as an age-related effect on dietary habits.

AIM: To study the influence of peripheral neuropathy on intermittent claudication in patients with Type 2 diabetes (T2DM). METHODS: Twenty-five patients with T2DM were grouped according to the ankle/brachial index (ABI): 10 with ABI > 0.9 without peripheral artery disease (PAD; group T2DM) and 15 with ABI < 0.9 with PAD (group T2DM + PAD). Twelve individuals without T2DM with PAD (group PAD without T2DM) were also enrolled. Tests for peripheral neuropathy were performed in all patients. ABI, rate pressure product, prothrombin fragments 1 + 2 (F1+2), thrombin-anti-thrombin complex (TAT), and d-dimer were measured before and after a treadmill test. During exercise both initial and absolute claudication distance and electrocardiogram readings were recorded. RESULTS: We found mild peripheral neuropathy in 20% of group T2DM and 46.7% of group T2DM + PAD (P < 0.01). After exercise, the rate pressure product increased in each group; ABI fell in T2DM + PAD (P < 0.0001) and in PAD without T2DM (P = 0.0005); the fall was greater in the latter group. Initial and absolute claudication distances were similar in PAD patients. In group T2DM + PAD, absolute claudication distance was longer in the subgroup without peripheral neuropathy (P < 0.05), whereas ABI and rate pressure products were similar. F1+2 values at rest were higher in group T2DM + PAD. After exercise, F1+2 values and TAT increased only in group PAD without T2DM. CONCLUSION: Only group PAD without T2DM experienced muscular ischaemia, whereas group T2DM + PAD did not. Mild peripheral neuropathy may have prevented them from reaching the point of muscular ischaemia during the treadmill test, because they stopped exercising with the early onset of pain. Reaching a false absolute claudication distance may induce ischaemic preconditioning. These findings suggest a possible protective role of mild peripheral neuropathy in T2DM patients with intermittent claudication, by preventing further activation of coagulation during treadmill testing.

The Mini-Mental State Examination (MMSE) is one of the most commonly used instruments in the evaluation of global cognitive status, but only few studies have investigated the relationship among its components in terms of factorial structure. We have considered data from the Italian Longitudinal Study on Aging (ILSA), carried out in Italy in 1992 on a sample of 5,632 subjects aged 65-84 years, and followed up in 1996. The aim of our study was to investigate static factorial structure in three groups of elderly (subjects with a diagnosis of dementia at baseline; subjects free of dementia at baseline, but incident cases at follow-up; subjects who never developed dementia during the 4-year follow-up). Considering our results, we could hypothesize that MMSE static structure reflects the cognitive profile of elderly, and is thus influenced by subjects' potential to develop dementia.

PURPOSE: To assess the effect of education on Disability Free Life Expectancy among older Italians, using a hierarchical model as indicator of disability, with estimates based on the multistate life table method and IMaCh software. METHODS: Data were obtained from the Italian Longitudinal Study on Aging which considered a random sample of 5632 individuals. RESULTS: Total life expectancy ranged from 16.5 years for men aged 65 years to 6 years for men aged 80. The age range for women was 19.6 and 8.4 years, respectively. For both sexes, increasing age was associated with a lower probability of recovery from a mild state of disability, with a greater probability of worsening for all individuals presenting an independent state at baseline, and with a greater probability of dying except for women from a mild state of disability. A medium/high educational level was associated with a greater probability of recovery only in men with a mild state of disability at baseline, and with a lower probability of worsening in both sexes, except for men with a mild state of disability at baseline. DISCUSSION: The positive effects of high education are well established in most research work and, being a modifiable factor, strategies focused on increasing level of education and, hence strengthening access to information and use of health services would produce significant benefits.

BACKGROUND AND OBJECTIVES: Our aim was to construct a harmonized measure of activities of daily living (ADL) across six countries, and to evaluate the reliability and validity of this measure. METHODS: A population of 9,297 persons, aged 65-89 years, was drawn from the Comparison of Longitudinal European Studies on Aging (CLESA) study, which includes data from five European countries and Israel. Because the number, type, and response format of the ADL items differed across the six studies, a four-item scale was constructed to harmonize the data, using items common to most countries. A procedure was devised to substitute or construct items that were not available in two of the countries. RESULTS: Cronbach's alpha for the four-item ADL measure varied from 0.81 in Spain to 0.92 in Finland, and was similar to the alpha of scales including five or six items. Kappa scores between substituted or constructed items and the actual items varied from 0.50 to 0.78. In all countries, the percentage of persons with ADL disability differed significantly across age and was associated with chronic diseases, poor self-rated health, global disability, and home help utilization. CONCLUSION: The harmonized four-item ADL measure seems a reliable and valid instrument for comparing ADL disability in older people across countries.

The associations between prevalence, incidence and recovery from activities of daily living (ADL) disability and social ties among community-dwelling persons over 65 in Finland, The Netherlands and Spain are examined. Data were harmonized in the CLESA study. The baseline sample was composed of 3,648 subjects between 65 and 85 years old, living in Finland, The Netherlands and Spain. Disability in four activities of daily living was determined at baseline and at follow-up. Social participation, number of family ties and presence of friends were added to obtain a social ties index. Logistic regressions were fitted to the prevalence, incidence and recovery data to estimate the associations between disability and social ties, adjusting for education, co-morbidity and self-rated health. The modifying effects of country, age and sex were tested in all models. For every country, the social ties index, having friends and social participation were negatively associated with ADL disability prevalence. ADL incidence was negatively related to the number of family ties, with a stronger relationship in Spain than in The Netherlands or Finland. ADL recovery was associated with the social ties index. No age or gender differences in these associations were found. Social ties appear to generate a beneficial effect on the maintenance and restoration of ADL function. While social ties play an important role in maintaining and restoring function in all three countries, family ties appear to generate a stronger effect on protection from disability incidence than does social participation, and the strength of this effect varies by culture.
RESUMEN
The improvement in cognitive performances due to cholinesterase inhibitors (ChEls) is not homogeneous among Alzheimer's disease (AD) subjects. Aim of this study is to evaluate whether a specific pattern of change in mini mental state examination (MMSE) could be observed in AD subjects after 9-month treatment with ChEls. From September 2000 to September 2002, 99 subjects enrolled in the CRONOS project. They have never been previously treated with ChEls. All of them completed both the 3- and the 9-month follow-up. The multidimensional assessment included MMSE, activity of daily living (ADL), instrumental activity of daily living (IADL), somatic health status, according to design of the CRONOSproject. The MMSE was analyzed both as a total score and disaggregated in 11 items. All subjects were divided in 2 groups according to the degree of change in MMSE total score from baseline to the 9th month. Subjects with a change = -1 were defined as non-responders(NR), whereas those with a change >0 as responders (R). At start, no statistically significant differences were found between the 2 groups. MMSE score was significantly higher in the R group both at 3 (p < 0.0001) and 9 months (p < 0.0001), while functional status (ADL and IADL) was significantly lower in NR group at 9 months (p = 0.025; p =0.018, respectively). In MMSE qualitative analysis of 3-month, NR significantly worsened in temporal (p = 0.05) and spatial orientation (p = 0.001), and in delayed recall items (p = 0.0005) in comparison to their counterpart. At 9-month the differences between the 2 groups were observed also for registration (p < 0.001), attention (p = 0.0005), obeying oral commands (p < 0.0005), reading and obeying commands (p = 0.0005), writing a sentence (p = 0.0005) and copying a design (p = 0.05). In a multivariate regression model, after adjustment for demographic (age, education, gender) and clinical factors (duration of disease), only the change at 3 months in 5 MMSE items (temporal and spatial orientation,delayed recall, obeying an oral command and reading and obeying command) is associated with global cognitive change observed at 9 months. Data suggest that the change in cognitive performances of AD subjects treated with ChEls involves few and specific MMSE items at 3-month, while it tend to generalize to almost all the others at 9-month treatment.

Disability-free life expectancy (DFLE) was compared in six countries taking part in the Cross-national Determinants of Quality of Life and Health Services for the Elderly (CLESA) project. Data from six existing longitudinal studies were used: TamELSA (Tampere, Finland), CALAS (Israel), ILSA (Italy), LASA (The Netherlands), Aging in Leganés (Leganés, Spain) and SATSA (Sweden). A harmonised four-item disability measure (bathing, dressing, transferring, toileting) was used to calculate DFLE; the harmonised measure was dichotomised into 'independent in all four activities' vs. 'dependent in at least one'. Calculations of DFLE were made using the multistate life table approach and the IMaCh program (INED/EuroREVES, http://eurorevesinedfr/imach/) for subjects aged 65-89 years. Prevalence ratios of disability varied significantly across countries, with Italy and Leganés having the highest percentages among men and among women, respectively, while The Netherlands presented the lowest for both sexes. At 75 years of age the estimated total life expectancy among men ranged from 7.8 years in Tampere and Sweden to 9.0 years in Israel; among women it ranged from 9.5 years in Israel to 11.6 years in Italy. For both sexes Italy showed the lowest total life expectancy without disability (72% among men, 61% among women) and Sweden the highest (89% among men and 71% among women). The results yielded a north/south gradient, with residents in Tampere, The Netherlands and Sweden expected to spend a higher percentage of their lives without disability than those in Italy, Israel and Leganés.
RESUMEN
BACKGROUND AND AIM: To evaluate the role of lipoprotein abnormalities as risk factors for macroangiopathy in Type 2 diabetes. METHODS AND RESULTS: This prospective nine-year follow-up study involved 113 Type 2 diabetic patients (50 men and 63 women, mean age 66.9 +/- 9.9 years), 37 of whom had clinical signs of coronary heart disease (CHD) and cerebrovascular disease (CVD) at baseline. During the follow-up, 32 patients died: 17 of CHD, five of CVD, and 10 of non-vascular causes. The patients who died because of vascular disease were more frequently smokers, and had baseline symptoms of vascular disease; they were also significantly different from the other patients insofar as they were older, and had higher fasting plasma glucose levels, lower fasting C-peptide levels, and lower apoprotein (apo) AII, apo CII, apo CIII and apo E levels. Univariate analysis showed that baseline symptoms of vascular disease, current smoking, age, high fasting plasma glucose levels, low fasting C-peptide levels, and low apo AII, apo CII, apo CIII and apo E levels [but not cholesterol, triglyceride, high-density lipoprotein (HDL)-cholesterol or qualitative low-density lipoprotein or HDL abnormalities] were associated with cardiovascular mortality. Multivariate analysis showed that only age, smoking, glycated hemoglobin (HbA1c) and fasting C-peptide levels were significant independent determinants of macrovascular death. CONCLUSIONS: In Type 2 normolipidemic diabetic patients, only age, smoking, HbA1c and fasting C-peptide levels are independent vascular risk factors. The differences in apo concentrations between patients with and without vascular disease may reflect qualitative abnormalities in plasma lipoproteins related to vascular disease.

Dementia is known to be associated with excess mortality. Physical disability, as a marker of dementia severity, is often considered the last step on the way from disease to death. The objective of this study was to investigate the direct effect of dementia on mortality in a population-based study, carried out in Italy, with a sample of 5,632 individuals aged 65-84 years. At 4-year follow-up, 998 participants had died. The independent predictors of death were: age (75-84 years; HR 2.63, CI = 2.11-3.27), male sex (HR 1.45, CI = 1.22-1.74), coronary heart disease (HR 1.61, CI = 1.34-1.94), moderate and severe instrumental activities of daily living disability (HR 1.98, CI = 1.30-3.03 and HR 3.26, CI = 2.09-5.09, respectively), diabetes in subjects with a survival time greater than 23 months (HR 0.68, CI = 0.43-1.08) and dementia (HR 2.07, CI = 1.62-2.66). These data provide evidence that dementia per se, independently from physical disability, is a strong predictor of death in the elderly.

BACKGROUND: The inverse relationship of insulin level to high-density lipoprotein (HDL)-cholesterol and its positive association with hypertriglyceridemia has been demonstrated in several studies; however, the relationship of insulin to low-density lipoprotein (LDL)-cholesterol in elderly persons is not clear. This study investigates the relationships of fasting plasma insulin and selected metabolic and biological risk factors in an aged population. METHODS: The present study is based on a cross-sectional analysis of the data collected at baseline of the Italian Longitudinal Study on Aging in 1992 on a random sample of 5632 Italians aged 65-84 years. Analyses were performed to compare the distribution of risk factors, such as blood level of lipids, creatinine, albumin, fibrinogen, apolipoprotein A-1 and B, blood pressure, and body mass index (BMI), by quartiles of insulin, in both diabetic and nondiabetic participants. RESULTS: Significantly higher levels of triglycerides and BMI and lower levels of HDL-cholesterol were found in the upper quartile of insulin among nondiabetic individuals. In men, we also found significantly higher levels of systolic and diastolic blood pressure. The same trend for these variables, although not significant for HDL-cholesterol and blood pressure, was seen in diabetic men. In diabetic women, total and LDL-cholesterol were significantly lower in the highest insulin quartile (p <.001), while no significant differences were seen in nondiabetic women or in men. We also found higher levels of white blood cells in the highest insulin quartile of diabetic women. CONCLUSIONS: These results, apparently in disagreement with earlier reports on the clustering of cardiovascular disease risk factors in hyperinsulinemic individuals, could be due to the high frequency of chronic inflammation and the high prevalence of urinary infections in older diabetic women.

BACKGROUND: Urinary incontinence (UI) is a common problem in elderly people, due mainly to functional impairments and concurrent medical diseases. Few studies, however, have assessed the prevalence of UI in noninstitutionalized individuals. The objectives of the present work were to estimate the prevalence of UI in a community-based population of elderly Italians and to determine the associated physical, social, and psychological factors. METHODS: A random sample of noninstitutionalized men (n = 867) and women (n = 1531), aged 65 years and older, from the Veneto region of northeastern Italy, were interviewed at home, using an extensive multidisciplinary questionnaire, to assess their quality of life and social, biological, and psychological correlates. RESULTS: The prevalence rate of UI was of 11.2% among men and of 21.6% among women. Among those reporting the condition, approximately 53% of women and 59% of men reported experiencing incontinence daily or weekly. Association of UI was found for participants older than 70 years in both men (odds ratio [OR] 2.49, 95% confidence interval [CI] 1.45-4.28) and women (OR 1.49, 95% CI 1.11-2.02). Three of the medical conditions investigated were associated with increases in the odds in women, namely chronic obstructive pulmonary disease (OR 1.53, 95% CI 1.11-2.12), Parkinsonism (OR 2.27, 95% CI 1.14-4.54), and hip fracture (OR 1.38,95% CI 1.02-1.88), whereas chronic diarrhea was the only condition associated with UI in men (OR 6.92, 95% CI 2.22-21.5). Participants with a physical disability were two times more likely to report incontinence, and the odds were increased by 50% in women who had sleep disturbances. CONCLUSIONS: Incontinence is highly prevalent in the Italian elderly population, and several common chronic conditions are significantly associated with it. Moreover, very few people with incontinence seek health care or are aware of potential treatments.

Carbohydrates (CHO) are a major determinant of post-prandial blood glucose in the diet of people with Type 1 diabetes mellitus, but patients frequently fail to evaluate CHO food content. Poor education is thought to contribute heavily to this failure. Our aim was to plan and evaluate a simple educational program to improve dietary knowledge and teach how to count CHO in Type 1 diabetic subjects. Forty-eight patients (age 27+/-1 yr, diabetes duration 11+/-1 yr, HbA1c 9%) attended 4 interactive meetings held at monthly intervals. The targets of the course were: 1) to identify sources of CHO, fats and proteins; 2) to count CHO and to split them among meals; 3) to assume CHO-rich foods without changing daily calorie or carbohydrate intake; 4) to modify the diet so as to correct hypoglycaemic events. To evaluate the effect of the course, patients completed a 7-day food record and answered a questionnaire covering the targets of the course at baseline, at the end of the course and 7 months later. After the course dietary knowledge improved significantly. The number of patients who weighed foods, estimated CHO food content and correctly distributed CHO among meals also increased. After the course patients reacted better when faced with hypoglycaemia. The knowledge acquired persisted 7 months after the end of the course. Therefore, we conclude that a simple teaching program can improve diet knowledge in Type 1 diabetics and establish a sustained habit of counting CHO.
