Background and aim: Benefits of oral anticoagulants (OAC) in atrial fibrillation (AF) patients with moderate-to-high risk of stroke are independent of AF pattern. We evaluated whether AF clinical subtype influenced OAC use in a representative sample of the Italian older population. Methods: A cross-sectional examination of all subjects aged 65 + years from three general practices in northern, central, and southern Italy started in 2016. A double-screening procedure was followed by clinical and ECG confirmation. Patients were categorized as having paroxysmal, persistent, or permanent AF. OAC use was evaluated in confirmed AF patients. Results: The sample included 6016 subjects. Excluding 235 non-eligible, participation was 78.3%, which left 4528 participants (mean age 74.5 ± 6.8 years, 47.2% men). Overall, 319 AF cases were identified: 43.0% had paroxysmal, 21.3% persistent, and 35.7% permanent AF. Frequency of OAC therapy was 91.2% in permanent, 85.3% in persistent, and only 43.0% in paroxysmal AF (P < 0.001). In multivariate analysis, controlled for baseline variables and risk scales, persistent and permanent AF were associated with a significant increase in the likelihood of receiving OAC compared with paroxysmal AF (P < 0.001). This was confirmed for permanent AF also in multivariate analyses considering separately vitamin K antagonists or direct-acting oral anticoagulants (OR, 4.37, 95% CI, 2.43–7.85; and 1.92, 95% CI, 1.07–3.42, respectively) and for persistent AF and direct-acting oral anticoagulants (OR, 4.33, 95% CI, 2.30–8.15). Conclusions: In a population-based survey, AF pattern was an independent predictor of OAC treatment. Paroxysmal AF is still perceived as carrying a lower risk of vascular events.

BACKGROUND/OBJECTIVES: Atrial fibrillation (AF) subtypes may carry different cardiovascular risk profiles, but information on their frequency from population‐based studies is lacking. We estimated prevalence of AF subtypes in a representative sample of the Italian older population, projecting figures for Italy and the European Union. DESIGN: Cross‐sectional study. SETTING: Three primary care practices in northern, central, and southern Italy. PARTICIPANTS: All individuals aged 65 years or older, for a total sample of 6,016 subjects. Excluding 235 noneligible, participation was 78.3%, which left 4,528 participants. MEASUREMENTS: A double systematic and opportunistic screening procedure identified possible AF cases, followed by clinical and electrocardiogram confirmation. Patients were categorized with paroxysmal, persistent, or permanent AF. Prevalence was calculated by sex and 5‐year age groups. Prevalence figures were applied to population projections for all 28 European Union states to estimate AF subtypes expected in future decades. RESULTS: In the 4,528 participants (mean age = 74.5 ± 6.8 years; 47.2% men), 331 AF cases were identified: 140 (42.3%) paroxysmal, 77 (23.3%) persistent, and 114 (34.4%) permanent. Prevalence was 3.1% (95% confidence interval (CI) = 2.6%–3.6%) for paroxysmal, 1.7% (95% CI = 1.4%–2.1%) for persistent, and 2.5% (95% CI = 2.1%–3.0%) for permanent AF. Italian older persons having AF in 2016 were estimated at approximately 449,000 for paroxysmal, approximately 240,000 for persistent, and approximately 391,000 for permanent AF, projected to increase in 2060 to approximately 785,000, approximately 358,000, and approximately 748,000, respectively. European Union older persons having AF in 2016 were estimated at approximately 3,185,000 for paroxysmal, approximately 1,722,000 for persistent, and approximately 2,710,000 for permanent AF, projected to increase in 2060 to approximately 5,989,000, approximately 2,833,000, and approximately 5,579,000, respectively. CONCLUSION: We provided first projections of AF subtypes for Italy and Europe. The worse cardiovascular risk profile of persistent and permanent forms indicates an increased burden in future decades.

Street sweeping services are integral to municipal solid waste management systems. The environmental impact of municipal solid waste management has been widely debated in the literature, but the specific impact of street sweeping services has not been fully studied. The aim of this study is to fill this literature gap by applying the life cycle assessment (LCA) methodology to compare the effects of different types of street sweeping services provided in two medium-sized Italian cities. The results show that fuel consumption is by far the largest contributor in all environmental impact categories, followed by the material consumption of the equipment. The study provides managerial and policy implications. The results can enable managers to lessen the environmental impact of sweeping services, and the findings can be applied by policy makers through Green Public Procurement procedures.

Background: Dementia, including Alzheimer's disease (AD), is one of the most burdensome medical conditions. In order to better understand the epidemiology of dementia in Italy, we conducted a systematic search of studies published between 1980 and April 2014 investigating the prevalence of dementia and AD in Italy and then evaluated the quality of the selected studies. Methods: A systematic search was performed using PubMed/Medline and Embase to identify Italian population-based studies on the prevalence of dementia among people aged ≥60 years. The quality of the studies was scored according to Alzheimer's Disease International (ADI) criteria. Results: Sixteen articles on the prevalence of dementia and AD in Italy were eligible and 75% of them were published before the year 2000. Only one study was a national survey, whereas most of the studies were locally based (Northern Italy and Tuscany). Overall, the 16 studies were attributed a mean ADI quality score of 7.6 (median 7.75). Conclusions: Available studies on the prevalence of dementia and AD in Italy are generally old, of weak quality, and do not include all regions of Italy. The important limitations of the few eligible studies included in our analysis, mostly related to their heterogeneous design, make our systematic review difficult to interpret from an epidemiologic point of view. Full implementation of a Dementia National Plan is highly needed to better understand the epidemiology of the disease and monitor dementia patients. [ABSTRACT FROM AUTHOR]

Stroke knowledge improves public behavior in terms of prevention, symptom recognition, and timely response. Contemporary data on stroke awareness in the Italian general population are lacking. This study surveyed public knowledge of risk factors, warning signs, and proper reactions to stroke among Italian adults. A population-based telephone survey was carried out in a sample of 1,000 residents aged ≥18 years in May-June 2010. The questionnaire included close-ended questions focused on stroke symptoms, risk factors, and treatment options. We examined the prevalence and distribution of stroke knowledge in the community and generated multivariable logistic regression models. Among the 1,000 participants (481 men, mean age 48.8 ± 17.2), only the 55.8 % correctly identified the brain as the affected organ in stroke. The most common risk factor for stroke identified by respondents was hypertension (67.6 %), the most common warning sign was hemiparesis (68.7 %), the 43.5 % could list >1 warning sign. Multivariate analyses indicate that education and previous stroke experience are the only independent predictors of stroke knowledge. Only 26.2 % reported to know about the availability of t-PA treatment. An ambulance would be called by 59 % of respondents in the event of a stroke. Respondents with a high level of education are more likely to call an ambulance in case of stroke. This study provides the first comprehensive data describing stroke knowledge among Italian adults: the general level is suboptimal and is associated only with education and previous family experience of stroke. Public education could potentially improve treatment and prevention. [ABSTRACT FROM AUTHOR]

Background and purpose The lack of a wide implementation of stroke units ( SU)s in Italy appears to accompany the underuse of the operating units. Community awareness of acute stroke care options may affect stroke resource use. Our aim was to determine the level of knowledge about SUs and tissue-plasminogen activator (t- PA) treatment amongst Italian adults and investigate its relationship to local stroke services implementation. Methods A nation-based telephone survey was carried out in a sample of 1000 residents aged >18 years in May-June 2010. The questionnaire included close-ended questions regarding knowledge of SUs and t- PA treatment. Number and location of both SUs and t- PA treatments were provided by a concurrent national hospital-based survey. The prevalence and distribution of acute stroke care awareness in the community was examined and multivariate analyses were generated. Results Amongst the 1000 participants (474 men, mean age 48.8 ± 17.2), only 26.2% reported knowing about the availability of t- PA treatment and only 15% were aware of the existence of SUs. Awareness of both SUs and t- PA was significantly associated only with education. These associations remained significant in the multivariate analyses. The degree of stroke services implementation (in terms of SUs/inhabitant rates and number of t- PA treatments) was not associated with SU and t- PA awareness. Conclusions This is the first European study that explored public knowledge about t- PA treatment and SUs. Italian adults proved insufficiently educated about SUs and t- PA; there is no higher awareness in areas with a greater supply of stroke services. This might partially explain the underuse of Italian SUs. [ABSTRACT FROM AUTHOR]

Access to effective acute stroke services is a crucial factor to reduce stroke-related death and disability, but is limited in different parts of Italy. Our study addresses this inequality across the Italian regions by examining the regional legislations issued to adopt and implement the State-Regional Council agreement 03/02/2005 as to the acute stroke management. All decrees and resolutions as to acute stroke were collected from each region and examined by the means of a check list including quantitative and qualitative characteristics, selected in accordance with the recommendations from the State-Regional Council document. Each completed check list was then sent to each regional reference person, who filled in the section on the implementation of the indications and compliance, with the collaboration of stroke specialists if necessary. The study was carried out from November 2009 to September 2010. The documents and information were collected from 19 regions. Our survey revealed disparities both in terms of number of decrees and resolutions and of topics covered by the regional legislations about stroke care. Most legislations lacked practical and economical details. This feedback from national and regional stroke regulations revealed a need of more concrete indications. Involvement of various stakeholders (legislators, consumers, providers) might possibly ensure that policies are actually adopted, implemented and maintained. Although considerable challenges are present to the development of standard and optimal stroke care more widely across Italian regions, the potential gains from such developments are substantial.

The Stroke Units (SUs) have been demonstrated to be efficient and cost effective for acute stroke care. Nevertheless, the level of stroke unit implementation in Italy does not correspond to expectations yet. This study is a survey, which aims at assessing the current status of in-hospital stroke care in the Italian regions and at updating SUs. The survey was conducted by means of a semi-structured questionnaire, based on 18 stroke care 'quality indicators', submitted to all the Italian centres that had taken part in the SITS-MOST study, and to other centres advised by the coordinator of SITS studies and by regional opinion leaders of stroke. SUs were defined as acute wards, with stroke-dedicated beds and dedicated teams that had been formally authorised to administer rt-PA. A statistical analysis was performed by a descriptive statistics and logistic regression model. The study was carried out from November 2009 to September 2010. A total of 168 forms were sent out and 153 replies received. Seven centres, which had not performed any thrombolytic treatment, and 16 which did not fulfil the criteria for the definition of SU were excluded from the study. Most of the centres reported more than 100 stroke patient admissions per year, i.e., 122 (84 %) from 100 to 500, 18 (12 %) more than 500. The 19 % of the centres admitted more than 30 % of patients within 3 h from the symptom onset and only 30 % admitted more than 30 % of patients within 4.5 h. The mean number of thrombolyses performed in the last 6 months was 10 for centres with a doctor on duty 24 h a day, 6 for those that have a doctor on duty from 8 a.m. to 8 p.m. and a doctor on call for night, and 5 for centres with a doctor on call 24 h a day. The territorial distribution of the SUs is remarkably heterogeneous: 87 SUs (67 %) are located in the North of Italy, 28 (22 %) in the central part of Italy and only 15 (11 %) in the South. The last few years have witnessed a rise in both the diffusion of SUs and access to thrombolytic therapy in Italy. Despite this, there are a few large areas, mostly in the south, where the requirements of healthcare legislation are not met, and access to a dedicated SU and thrombolytic treatment is still limited and poor.

Cognition has already been considered as a component of frailty, and it has been demonstrated that it is associated with adverse health outcomes. We estimated the prevalence of frailty syndrome in an Italian older population and its predictive role on all-cause mortality and disability in nondemented subjects and in demented patients. We evaluated 2,581 individuals recruited from the Italian Longitudinal Study on Aging, a population-based sample of 5,632 subjects, aged 65-84 years old. Participants received identical baseline evaluation at the 1st survey (1992-1993) and were followed at 2nd (1995-1996) and 3rd survey (2000-2001). A phenotype of frailty according to partially modified measurement of Cardiovascular Health Study criteria was operationalized. The overall prevalence of frailty syndrome in this population-based study was 7.6% (95% confidence interval (CI) 6.55-8.57). Frail individuals noncomorbid or nondisable were 9.1% and 39.3%, respectively, confirming an overlap but not concordance in the co-occurrence among these conditions. Frailty was associated with a significantly increased risk of all-cause mortality over a 3-year follow-up (hazard ratio (HR) 1.98, 95% confidence interval (CI) 1.52-2.60) and over a 7-year follow-up (HR 1.74, 95% CI 1.44-2.16), but with significant increased risk of disability only over a 3-year follow-up (HR 1.32, 95% CI 1.06-1.86 over a 3-year follow-up and HR 1.16, 95% CI 0.88-1.56 over a 7-year follow-up). Frail demented patients were at higher risk of all-cause mortality over 3- (HR 3.33, 95% CI 1.28-8.29) and 7-year follow-up periods (HR 1.89, 95% CI 1.10-3.44), but not of disability. Frailty syndrome was a short-term predictor of disability in nondemented older subjects and short- and long-term predictor of all-cause mortality in nondemented and demented patients.

OBJECTIVES: To examine risk and predictors of motor-performance (MP) decline targeting subjects performing normally at an initial observation. DESIGN: Cohort study. SETTING: A subsample of the Italian Longitudinal Study on Aging (aged 65–84). PARTICIPANTS: One thousand fifty-two subjects (mean age±standard deviation=71±5, 69% men) with normal MP at baseline. MEASUREMENTS: Six tests (standing up from a chair, stepping up, tandem walk, standing on one leg, walking speed, and steps turning 180°) were used to assess MP at baseline and after 3 years. Baseline characteristics were potential predictors of MP decline. RESULTS: Of the 1,052 subjects performing normally at baseline, 166 (15.8%) had declined in MP at follow-up. Older age, female sex, lower education, symptoms of distal symmetrical neuropathy, cognitive impairment without dementia, parkinsonism, heart failure, anemia, depressive symptoms, worse Mini-Mental State Examination score, and lost activities of daily living and instrumental activities of daily living (IADLs) were significantly associated with MP decline in univariate comparisons. Older age (odds ratio (OR)=3.84, 95% confidence interval (CI)=2.14–6.88 comparing age classes ≥80 with 65–69), female sex (OR=1.50, 95% CI=1.03–2.20), distal symmetric neuropathy (OR=2.00, 95% CI=1.03–3.87), depressive symptoms (OR=1.85, 95% CI=1.17–2.24), and baseline IADLs (OR=1.22, 95% CI=1.08–1.37 for each lost activity) independently predicted MP decline after regression analysis. CONCLUSION: In a population-based cohort of elderly people with normal MP, one-sixth declined in 3 years. Age, sex, distal symmetrical neuropathy, depressive symptoms, and baseline IADLs independently predicted this decline. Distal symmetrical neuropathy is underestimated in the clinical and epidemiological evaluation of motor decline in older people. [ABSTRACT FROM AUTHOR]

Background and Purpose: Data on stroke morbidity are lacking in southern Italy, an area with about 20 million inhabitants and a mean income lower than the rest of the country. Therefore a population-based stroke register was established to determine incidence and case fatality in the Province of Vibo Valentia, Calabria. Methods: The survey was conducted among the 179,186 residents. Standard definitions and multiple case-finding procedures were employed. All identified cases of first-ever stroke were followed at 28 days, 3 and 12 months. The registration started on January 1, 1996, and ended on December 31, 1996. Results: A total of 321 first-ever-in-a-lifetime strokes were identified. The crude annual incidence rate was 1.79 (95% CI 1.60-1.99) per 1,000 inhabitants. Rates age-standardized to the 1996 Italian population and to the standard European population were, respectively, 1.99 (95% CI 1.79-2.20) and 1.36 (95% CI 1.19-1.53) per 1,000 inhabitants. A subtype diagnosis was reached in 96% of patients. The crude annual incidence rates per 1,000 inhabitants were 1.31 for cerebral infarction, 0.35 for intracerebral hemorrhage, 0.06 for subarachnoid hemorrhage, and 0.07 for unspecified stroke. Overall case fatality was 23.7% at 28 days, 27.4% at 3 months and 40.2% at 12 months. Conclusions: This is the first prospective population-based stroke register established in southern Italy. Incidence and case fatality were comparable to those previously reported in northern and central Italy and other industrialized countries. Our estimates are useful for developing management services and allocating resources. [ABSTRACT FROM AUTHOR]

Objectives – To investigate the association of major lifestyle-related risk factors with the prevalent cases of Parkinson's disease (PD) identified by the Italian Longitudinal Study on Aging. Methods – A total of 5632 individuals randomly selected from the population registers of eight centers were screened for parkinsonism using both a questionnaire and a neurologic examination. Screened positives underwent a structured clinical work-up for the diagnosis of parkinsonism and parkinsonism subtypes. Results – We identified 113 prevalent cases of PD. Age, male gender, and pesticide-use license were significantly related to PD. Heavy smoking was inversely related to PD. Age (OR = 1.1; 95% CI, 1.06–1.15) and pesticide-use license (OR = 3.7; 95% CI, 1.6–8.6) kept their significant correlation with the disease in the multivariate analysis to adjust for all the variables under investigation. Multivariate analyses were made for men and women separately: pesticide exposure was positively associated with PD only in men. Conclusions – Pesticide exposure might represent a candidate for environmental factors involved in PD. [ABSTRACT FROM AUTHOR]

Background: Epidemiological data are essential to estimate the burden of stroke. We evaluated stroke incidence in older Italians and the effect of first-ever stroke on survival and activities of daily living (ADL). Methods: The analysis was performed in the Italian Longitudinal Study on Aging (ILSA) sample, consisting of 5,632 individuals aged 65-84. The ILSA aims at major cardiovascular and neurological age-associated diseases. The baseline survey was performed in 1992 to detect prevalent diseases. The longitudinal examination started on September 1995 aiming at incidence, function and survival. Results: Complete follow-up data were achieved for 77% of the baseline stroke-free cohort (4,164 persons; 50.9% males; mean age 74.5 ± 5.7 years). Incidence for firstever stroke was 9.51 (95% CI: 7.75-11.27) per 1,000 person years and 12.99 (95% CI: 10.99-14.98) including recurrent stroke (total incidence). Crude mortality was 49.2% among first stroke patients and 15% among persons without stroke. The first-ever stroke mortality risk ratio, adjusted for demographics and comorbidity, was 2.40 (95% CI: 1.62-3.54). In survivors, impairment of at least one ADL was present in 67.6% of first-ever stroke patients vs. 31.6% of individuals without stroke. The comorbidity-adjusted OR was 2.63 (95% CI: 1.20-5.78) in the total cohort, and 4.00 (95% CI: 1.39-11.46) in individuals without disability at baseline. Conclusions: The ILSA provides the first data on stroke incidence in Italy on a national basis. Overall, 153,000 new cases can be expected annually in the Italian elderly population. Firstever stroke still has a strong effect on survival and function of older persons. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To estimate the incidence of dementia, Alzheimer's disease (AD), and vascular dementia (VaD) in older Italians and evaluate the relationship of age, gender, and education to developing dementia. DESIGN: Cohort incidence study in the context of the Italian Longitudinal Study on Aging. SETTING: Population sample from eight Italian municipalities. PARTICIPANTS: A dementia-free cohort of 3,208 individuals (aged 65–84), individuated after a baseline evaluation performed in 1992 / 93, aimed at detecting prevalent cases. MEASUREMENTS: The dementia-free cohort was reexamined in 1995 to identify incident cases. The Mini-Mental State Examination (cutoff 23 / 24) was employed to screen for dementia. Trained neurologists evaluated the individuals who screened positive. Final diagnoses had to meet Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria for dementia, National Institute of Neurological and Communicative Disorders and Stroke—Alzheimer's Disease and Related Disorders Association criteria for AD, and International Classification of Diseases, Tenth Revision criteria for VaD. RESULTS: Before the follow-up examination, 382 individuals had died (232 had reliable information). Of the 2,826 survivors, 2,266 completed the study. Overall, 127 new dementia cases were identified. Average incidence rates per 1,000 person-years were 12.47 (95% confidence interval (CI) = 10.23–14.72) for dementia, 6.55 (95% CI = 4.92–8.17) for AD, and 3.30 (95% CI = 2.14–4.45) for VaD. Both AD and VaD showed age-dependent patterns. Education was protective against dementia and AD. Women carried a significantly higher risk of developing AD (hazard ratio = 1.67, 95% CI = 1.02–2.75), and men of developing VaD (hazard ratio = 2.23, 95% CI = 1.06–4.71). CONCLUSIONS: Incidence of dementia in Italy paralleled that in most industrialized countries. About 150,000 new cases per year are expected. A significant... [ABSTRACT FROM AUTHOR]

We sought to compare construct and predictive validity of four sets of heart failure (HF) diagnostic criteria in an epidemiologic setting.The prevalence estimates of HF vary broadly depending on the diagnostic criteria.Data were collected in a survey of community dwellers who were ≥65 years of age living in Dicomano, Italy. At baseline, HF was diagnosed with the criteria of the Framingham, Boston, and Gothenburg studies and of the European Society of Cardiology (ESC). Left ventricular mass index and ejection fraction, left atrium systolic dimension, lower extremity mobility disability, summary physical performance score, and 6-min walk test were compared between HF and non-HF participants to test for construct validity of each set of criteria. Predictive validity was evaluated with follow-up assessment of cardiovascular mortality, incident disability, and HF-related hospitalizations. Comparisons were adjusted for demographics, comorbidity, and psychoaffective status.Of 553 participants, 11.9%, 10.7%, 20.8%, and 9.0% had HF, according to Framingham, Boston, Gothenburg, and ESC criteria, respectively. In terms of construct validity, Framingham and Boston criteria discriminated HF from non-HF participants better than Gothenburg and ESC criteria across the measures of cardiac function and global performance. The Boston criteria showed a superior predictive validity because they indicated a significantly greater adjusted risk of cardiovascular death (hazard ratio3.9, 95% confidence interval 1.2 to 13.2), incident disability, and hospitalizations in participants with HF.The Boston criteria are preferable to Framingham, Gothenburg, and ESC criteria for the diagnosis of HF in older community dwellers because they have good construct validity and more accurately predict cardiovascular death, incident disability, and hospitalizations.

Objectives Cognitive frailty, a condition describing the simultaneous presence of physical frailty and mild cognitive impairment, has been recently defined by an international consensus group. We estimated the predictive role of a “reversible” cognitive frailty model on incident dementia, its subtypes, and all-cause mortality in nondemented older individuals. We verified if vascular risk factors or depressive symptoms could modify this predictive role. Design Longitudinal population-based study with 3.5- and 7-year of median follow-up. Setting Eight Italian municipalities included in the Italian Longitudinal Study on Aging. Participants In 2150 older individuals from the Italian Longitudinal Study on Aging, we operationalized reversible cognitive frailty with the presence of physical frailty and pre-mild cognitive impairment subjective cognitive decline, diagnosed with a self-report measure based on item 14 of the Geriatric Depression Scale. Measurements Incidence of dementia, its subtypes, and all-cause mortality. Results Over a 3.5-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia [hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.02–5.18], particularly vascular dementia (VaD), and all-cause mortality (HR 1.74, 95% CI 1.07–2.83). Over a 7-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia (HR 2.12, 95% CI 1.12–4.03), particularly VaD, and all-cause mortality (HR 1.39, 95% CI 1.03–2.00). Vascular risk factors and depressive symptoms did not have any effect modifier on the relationship between reversible cognitive frailty and incident dementia and all-cause mortality. Conclusions A model of reversible cognitive frailty was a short- and long-term predictor of all-cause mortality and overall dementia, particularly VaD. The absence of vascular risk factors and depressive symptoms did not modify the predictive role of reversible cognitive frailty on these outcomes. [ABSTRACT FROM AUTHOR]
