Turfgrass is a major vegetation type in urban and peri-urban areas. Being high maintenance ecosystems, turfs can contribute substantially to urban climate change. The object of this study was to evaluate the contribution to GHG emissions by urban turfgrasses in Mediterranean conditions (Tuscany, central Italy). CO2 and CH4 emission fluxes from a mature stand of tall fescue and bermudagrass were evaluated, by static chambers method, for the assessment of C emission under different nitrogen fertilization rates (0 - 50 - 150 kg N ha-1 ). Both species showed a correlation between N fertilization rate and CO2 emissions, whilst, no correlation was observed for CH4. In the case of tall fescue, cumulative CO2 emissions were significantly higher with 150 kg N ha-1 and no differences were observed between 0 and 50 kg N ha-1 . As for bermudagrass differences were found between control and other treatments but no differences were observed on cumulative CO2 emissions between 50 and 150 kg N ha-1 . In both species, N fertilization did not affect CH4 emissions. Results indicate that both N rate and turfgrass species influence C emissions, for this reason they should be considered in the management of green areas in the climatic transition zone.

Despite the remarkable and progressive advances made in the prevention and management of cardiovascular diseases, the recurrence of cardiovascular events remains unacceptably elevated with a notable size of the residual risk. Indeed, in patients who suffered from myocardial infarction or who underwent percutaneous or surgical myocardial revascularization, life-style changes and optimized pharmacological therapy with antiplatelet drugs, lipid lowering agents, beta-blockers, renin angiotensin system inhibitors and antidiabetic drugs, when appropriate, are systematically prescribed but they might be insufficient to protect from further events. In such a context, an increasing body of evidence supports the benefits of cardiac rehabilitation (CR) in the setting of secondary cardiovascular prevention, consisting in the reduction of myocardial oxygen demands, in the inhibition of atherosclerotic plaque progression and in an improvement of exercise performance, quality of life and survival. However, prescription and implementation of CR programs is still not sufficiently considered.The aim of this position paper of the Italian Society of Cardiovascular Prevention (SIPREC) and of the Italian Heart Failure Association (ITAHFA) is to examine the reasons of the insufficient use of this strategy in clinical practice and to propose some feasible solutions to overcome this clinical gap., (© 2024.

Aims: Patients with heart failure (HF) remain often undertreated for multiple reasons, including treatment inertia, contraindications, and intolerance. The OPTIimal PHARMacological therapy for patients with Heart Failure (OPTIPHARM-HF) registry is designed to evaluate the prevalence of evidence-based medical treatment prescription and titration, as well as the causes of its underuse, in a broad real-world population of consecutive patients with HF across the whole ejection fraction spectrum and among different clinical phenotypes., Methods: The OPTIPHARM-HF registry (NCT06192524) is a prospective, multicenter, observational, national study of adult patients with symptomatic HF, as defined by current international guidelines, regardless of ejection fraction. Both outpatients and inpatients with chronic and acute decompensated HF will be recruited. The study will enroll up to 2500 patients with chronic HF at approximately 35 Italian HF centres. Patients will be followed for a maximum duration of 24 months. The primary objective of the OPTIPHARM-HF registry is to assess prescription and adherence to evidence-based guideline-directed medical therapy (GDMT) in patients with HF. The primary outcome is to describe the prevalence of GDMT use according to target guideline recommendation. Secondary objectives include implementation of comorbidity treatment, evaluation of sequence of treatment introduction and up-titration, description of GDMT implementation in the specific HF population, main causes of GDMT underuse, and assessment of cumulative rate of cardiovascular events., Conclusion: The OPTIPHARM-HF registry will provide important implications for improving patient care and adoption of recommended medical therapy into clinical practice among HF patients., (© 2024 The Authors.

Objectives: This study aimed to investigate the psychological impact of the COVID-19 pandemic on healthcare workers (HCWs) in geriatric settings., Design: Online cross-sectional survey., Settings and Participants: 394 geriatric HCWs in Italy., Measurements: The survey was developed by a multidisciplinary team and disseminated in April 2022 to the members of two geriatric scientific societies (Italian Society of Geriatrics and Gerontology and Italian Association of Psychogeriatrics). The survey examined the experiences related to the COVID-19 pandemic, as well as psychological burden and support. Work-related anxiety and distress related to the pandemic were studied using the SAVE-9 scale (Stress and Anxiety to Viral Epidemics)., Results: Three hundred sixty-four participants (92.4%) changed their job activity during the pandemic and about half (50.9%) failed to cope with this change, 58 (14.7%) had increased work-related anxiety, and 39 (9.9%) work-related stress levels. Three hundred forty (86.3%) participants reported acute stress reaction symptoms, including irritability, depressed mood, headache, anxiety, and insomnia, and 262 (66.5%) required psychological support, mainly from friends/relatives (57.9%) and/or colleagues (32.5%). Furthermore, 342 participants (86.8%) recognized they would benefit from informal and formal psychological support in case of future similar emergencies., Conclusions: This study highlights the high psychological burden experienced by geriatric HCWs in Italy during the COVID-19 pandemic and emphasizes the need for supportive interventions., Competing Interests: The authors declared no conflict of interest to disclose.

Data concerning the combined prognostic role of natriuretic peptide (NP) and troponin in patients with COVID-19 are lacking. The aim of the study is to evaluate the combined prognostic value of NPs and troponin in hospitalized COVID-19 patients. From March 1, 2020 to April 9, 2020, consecutive patients with COVID-19 and available data on cardiac biomarkers at admission were recruited. Patients admitted for acute coronary syndrome were excluded. Troponin levels were defined as elevated when greater than the 99 th percentile of normal values. NPs were considered elevated if above the limit for ruling in acute heart failure (HF). A total of 341 patients were included in this study, mean age 68 ± 13 years, 72% were men. During a median follow-up period of 14 days, 81 patients (24%) died. In the Cox regression analysis, patients with elevated both NPs and troponin levels had higher risk of death compared with those with normal levels of both (hazard ratio 2.94; 95% confidence interval 1.31 to 6.64; p = 0.009), and this remained significant after adjustment for age, gender, oxygen saturation, HF history, and chronic kidney disease. Interestingly, NPs provided risk stratification also in patients with normal troponin values (hazard ratio 2.86; 95% confidence interval 1.21 to 6.72; p = 0.016 with high NPs levels). These data show the combined prognostic role of troponin and NPs in COVID-19 patients. NPs value may be helpful in identifying patients with a worse prognosis among those with normal troponin values. Further, NPs' cut-point used for diagnosis of acute HF has a predictive role in patients with COVID-19., Competing Interests: Disclosures Prof Piergiuseppe Agostoni reported nonfinancial support from Menarini, Novartis, and Boehringer; grants from Daiichiò Sankyo and Bayer; and grants and nonfinancial support from Actelion outside the submitted work.

Aims: To assess the clinical relevance of a history of atrial fibrillation (AF) in hospitalized patients with coronavirus disease 2019 (COVID-19)., Methods and Results: We enrolled 696 consecutive patients (mean age 67.4 ± 13.2 years, 69.7% males) admitted for COVID-19 in 13 Italian cardiology centres between 1 March and 9 April 2020. One hundred and six patients (15%) had a history of AF and the median hospitalization length was 14 days (interquartile range 9-24). Patients with a history of AF were older and with a higher burden of cardiovascular risk factors. Compared to patients without AF, they showed a higher rate of in-hospital death (38.7% vs. 20.8%; P < 0.001). History of AF was associated with an increased risk of death after adjustment for clinical confounders related to COVID-19 severity and cardiovascular comorbidities, including history of heart failure (HF) and increased plasma troponin [adjusted hazard ratio (HR): 1.73; 95% confidence interval (CI) 1.06-2.84; P = 0.029]. Patients with a history of AF also had more in-hospital clinical events including new-onset AF (36.8% vs. 7.9%; P < 0.001), acute HF (25.3% vs. 6.3%; P < 0.001), and multiorgan failure (13.9% vs. 5.8%; P = 0.010). The association between AF and worse outcome was not modified by previous or concomitant use of anticoagulants or steroid therapy (P for interaction >0.05 for both) and was not related to stroke or bleeding events., Conclusion: Among hospitalized patients with COVID-19, a history of AF contributes to worse clinical course with a higher mortality and in-hospital events including new-onset AF, acute HF, and multiorgan failure. The mortality risk remains significant after adjustment for variables associated with COVID-19 severity and comorbidities., (Published on behalf of the European Society of Cardiology.

Aims: Myocardial injury (MI) in coronavirus disease-19 (COVID-19) is quite prevalent at admission and affects prognosis. Little is known about troponin trajectories and their prognostic role. We aimed to describe the early in-hospital evolution of MI and its prognostic impact., Methods and Results: We performed an analysis from an Italian multicentre study enrolling COVID-19 patients, hospitalized from 1 March to 9 April 2020. MI was defined as increased troponin level. The first troponin was tested within 24 h from admission, the second one between 24 and 48 h. Elevated troponin was defined as values above the 99th percentile of normal values. Patients were divided in four groups: normal, normal then elevated, elevated then normal, and elevated. The outcome was in-hospital death. The study population included 197 patients; 41% had normal troponin at both evaluations, 44% had elevated troponin at both assessments, 8% had normal then elevated troponin, and 7% had elevated then normal troponin. During hospitalization, 49 (25%) patients died. Patients with incident MI, with persistent MI, and with MI only at admission had a higher risk of death compared with those with normal troponin at both evaluations (P < 0.001). At multivariable analysis, patients with normal troponin at admission and MI injury on Day 2 had the highest mortality risk (hazard ratio 3.78, 95% confidence interval 1.10-13.09, P = 0.035)., Conclusions: In patients admitted for COVID-19, re-test MI on Day 2 provides a prognostic value. A non-negligible proportion of patients with incident MI on Day 2 is identified at high risk of death only by the second measurement., (© 2021 The Authors.

Background: Pulmonary embolism (PE) has been described in coronavirus disease 2019 (COVID-19) critically ill patients, but the evidence from more heterogeneous cohorts is limited., Methods: Data were retrospectively obtained from consecutive COVID-19 patients admitted to 13 Cardiology Units in Italy, from March 1st to April 9th, 2020, and followed until in-hospital death, discharge, or April 23rd, 2020. The association of baseline variables with computed tomography-confirmed PE was investigated by Cox hazards regression analysis. The relationship between D-dimer levels and PE incidence was evaluated using restricted cubic splines models., Results: The study included 689 patients (67.3 ± 13.2 year-old, 69.4% males), of whom 43.6% were non-invasively ventilated and 15.8% invasively. 52 (7.5%) had PE over 15 (9-24) days of follow-up. Compared with those without PE, these subjects had younger age, higher BMI, less often heart failure and chronic kidney disease, more severe cardio-pulmonary involvement, and higher admission D-dimer [4344 (1099-15,118) vs. 818.5 (417-1460) ng/mL, p < 0.001]. They also received more frequently darunavir/ritonavir, tocilizumab and ventilation support. Furthermore, they faced more bleeding episodes requiring transfusion (15.6% vs. 5.1%, p < 0.001) and non-significantly higher in-hospital mortality (34.6% vs. 22.9%, p = 0.06). In multivariate regression, only D-dimer was associated with PE (HR 1.72, 95% CI 1.13-2.62; p = 0.01). The relation between D-dimer concentrations and PE incidence was linear, without inflection point. Only two subjects had a baseline D-dimer < 500 ng/mL., Conclusions: PE occurs in a sizable proportion of hospitalized COVID-19 patients. The implications of bleeding events and the role of D-dimer in this population need to be clarified.

Background: Glucocorticoid therapy has emerged as an effective therapeutic option in hospitalized patients with coronavirus disease 2019 (COVID-19). This study aimed to focus on the impact of relevant clinical and laboratory factors on the protective effect of glucocorticoids on mortality., Methods: A sub-analysis was performed of the multicenter Cardio-COVID-Italy registry, enrolling consecutive patients with COVID-19 admitted to 13 Italian cardiology units between 01 March 2020 and 09 April 2020. The primary endpoint was in-hospital mortality., Results: A total of 706 COVID-19 patients were included (349 treated with glucocorticoids, 357 not treated with glucocorticoids). After adjustment for relevant covariates, use of glucocorticoids was associated with a lower risk of in-hospital mortality (adjusted HR 0.44; 95% CI 0.26-0.72; p = 0.001). A significant interaction was observed between the protective effect of glucocorticoids on mortality and PaO 2 /FiO 2 ratio on admission (p = 0.042), oxygen saturation on admission (p = 0.017), and peak CRP (0.023). Such protective effects of glucocorticoids were mainly observed in patients with lower PaO 2 /FiO 2 ratio (<300), lower oxygen saturation (<90%), and higher CRP (>100 mg/L)., Conclusions: The protective effects of glucocorticoids on mortality in COVID-19 were more evident among patients with worse respiratory parameters and higher systemic inflammation., (Copyright © 2021 The Authors.

Aims: To assess the prognostic value of a history of heart failure (HF) in patients with coronavirus disease 2019 (COVID-19)., Methods and Results: We enrolled 692 consecutive patients admitted for COVID-19 in 13 Italian cardiology centres between 1 March and 9 April 2020. Mean age was 67.4 ± 13.2 years, 69.5% of patients were males, 90 (13.0%) had a history of HF, median hospitalization length was 14 days (interquartile range 9-24). In-hospital death occurred in 37 of 90 patients (41.1%) with HF history vs. 126 of those with no HF history (20.9%). The increased risk of death associated with HF history remained significant after adjustment for clinical variables related to COVID-19 and HF severity, including comorbidities, oxygen saturation, lymphocyte count and plasma troponin [adjusted hazard ratio (HR) for death: 2.25; 95% confidence interval (CI) 1.26-4.02; P = 0.006 at multivariable Cox regression model including 404 patients]. Patients with a history of HF also had more in-hospital complications including acute HF (33.3% vs. 5.1%, P < 0.001), acute renal failure (28.1% vs. 12.9%, P < 0.001), multiorgan failure (15.9% vs. 5.8%, P = 0.004) and sepsis (18.4% vs. 8.9%, P = 0.006). Other independent predictors of outcome were age, sex, oxygen saturation and oxygen partial pressure at arterial gas analysis/fraction of inspired oxygen ratio (PaO 2 /FiO 2 ). In-hospital treatment with corticosteroids and heparin had beneficial effects (adjusted HR for death: 0.46; 95% CI 0.29-0.74; P = 0.001; n = 404 for corticosteroids, and adjusted HR 0.41; 95% CI 0.25-0.67; P < 0.001; n = 364 for heparin)., Conclusions: Hospitalized patients with COVID-19 and a history of HF have an extremely poor outcome with higher mortality and in-hospital complications. HF history is an independent predictor of increased in-hospital mortality., (© 2020 European Society of Cardiology.)

Importance: Myocardial injury, detected by elevated plasma troponin levels, has been associated with mortality in patients hospitalized with coronavirus disease 2019 (COVID-19). However, the initial data were reported from single-center or 2-center studies in Chinese populations. Compared with these patients, European and US patients are older, with more comorbidities and higher mortality rates., Objective: To evaluate the prevalence and prognostic value of myocardial injury, detected by elevated plasma troponin levels, in a large population of White Italian patients with COVID-19., Design, Setting, and Participants: This is a multicenter, cross-sectional study enrolling consecutive patients with laboratory-confirmed COVID-19 who were hospitalized in 13 Italian cardiology units from March 1 to April 9, 2020. Patients admitted for acute coronary syndrome were excluded. Elevated troponin levels were defined as values greater than the 99th percentile of normal values., Main Outcomes and Measures: Clinical characteristics and outcomes stratified as elevated or normal cardiac troponin levels at admission, defined as troponin T or troponin I at a level greater than the 99th percentile of normal values., Results: A total of 614 patients with COVID-19 were included in this study (mean age [SD], 67 [13] years; 70.8% male), of whom 148 patients (24.1%) died during the hospitalization. Elevated troponin levels were found in 278 patients (45.3%). These patients were older (mean [SD] age, 64.0 [13.6] years vs 71.3 [12.0] years; P < .001) and had higher prevalence of hypertension (168 patients [50.5%] vs 182 patients [65.9%]; P < .001), heart failure (24 [7.2%]; 63 [22.8%]; P < .001), coronary artery disease (50 [15.0%] vs 87 [31.5%]; P < .001), and atrial fibrillation (33 [9.9%] vs 67 [24.3%]; P < .001). Elevated troponin levels were associated with an increased in-hospital mortality (37% vs 13%; HR, 1.71 [95% CI, 1.13-2.59]; P = .01 via multivariable Cox regression analysis), and this was independent from concomitant cardiac disease. Elevated troponin levels were also associated with a higher risk of in-hospital complications: heart failure (44 patients [19.2%] vs 7 patients [2.9%]; P < .001), sepsis (31 [11.7%] vs 21 [6.4%]; P = .03), acute kidney failure (41 [20.8%] vs 13 [6.2%]; P < .001), multiorgan failure (21 [10.9%] vs 6 [2.9%]; P = .003), pulmonary embolism (27 [9.9%] vs 17 [5.2%]; P = .04), delirium (13 [6.8%] vs 3 [1.5%]; P = .02), and major bleeding (16 [7.0%] vs 4 [1.6%]; P = .008)., Conclusions and Relevance: In this multicenter, cross-sectional study of Italian patients with COVID-19, elevated troponin was an independent variable associated with in-hospital mortality and a greater risk of cardiovascular and noncardiovascular complications during a hospitalization for COVID-19.

Aims: The aims of this study were to evaluate if the risk of cardiovascular events and all-cause mortality was higher in the presence of hyperkalaemia (HK) in patients with heart failure (HF) treated with renin-angiotensin-aldosterone system inhibitors (RAASi), and to investigate in this cohort the increased risk of cardiovascular events and all-cause mortality among HK patients with non-optimal adherence to RAASi therapy., Methods and Results: In this retrospective cohort study based on administrative databases of five Italian Local Health Units, all adult patients with a HF diagnosis between January 2010 and December 2017 were included only if they were prescribed RAASi therapy during the first 3 months after the index date, that corresponded to the date of first HF diagnosis during the inclusion period. Patients were considered to have HK if serum potassium level was ≥5.5 mmol/L. A propensity score matching was applied before evaluation of hazard ratios. Patients with HK were 37% (P < 0.001) and 70% (P < 0.001), respectively, more at risk of cardiovascular events and of dying for all-cause mortality compared to non-HK patients. Among the HK group, patients non-adherent to RAASi therapy had a 39% (P = 0.105) higher risk of cardiovascular events and a twofold increased risk (P < 0.001) of all-cause death., Conclusion: Findings from this real-world study showed that in a cohort of HF patients under RAASi therapy, subjects with HK had an enhanced risk of cardiovascular events or death compared to patients without HK. Moreover, in HK patients, sub-optimal adherence to RAASi therapy was associated with an increased risk of all-cause mortality., (© 2020 The Authors.

In the past few years, new oral anticoagulants (NOACs) targeting directly a single activated clotting factor, have been developed for the treatment of non-valvular atrial fibrillation (AF), which are currently recommended as first-line therapy in AF. The aim of this study is to provide an overall picture on the extent to which oral anticoagulation (OAC) with NOACs correspond to actually prescribed OAC therapy in an unselected, real world, population of consecutive patients with AF in Italy. Compliance with the therapy and quality of life were also assessed. A 50 cardiology unit network located in different geographic areas of Italy enrolled a total of 1742 consecutive outpatients with AF (54.6% males, 45.4% females, mean age 72.5 years). NOACs were prescribed in 56.1% patients and VKA in 43.9% (P < 0.0001). NOACs were significantly more prescribed than VKA in patients with high thrombo-embolic risk score (i.e., CHA 2 DS 2 -VASc > 2) (78.2 vs 67.3%, P < 0.0001), but also patients at low risk (i.e., CHA 2 DS 2 -VASc < 1 and HAS-BLED < 3) were still under OAC therapy with either NOACs (27%) or VKA (73%). Adherence to therapy (Morisky test) was greater in patients taking NOACs as was the quality of life. The ISPAF-2 study shows that in an Italian population of real-world patients with AF the prescription of OAC according to current guidelines and stroke-risk scoring system is rather high although it still needs to be improved. Contrary to recommendations, in a high proportion of low-risk patients, anticoagulation therapy, with either NOACs and VKA is still prescribed, and this exposes patients to unjustified risks.

Background: The Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (GICR-IACPR) and the Italian Society of Cardiologists of Accredited Hospitals (SICOA) developed the ISYDE.13 survey with the purpose to take a detailed snapshot of number, distribution, facilities, staffing levels, organization, and program details of cardiac rehabilitation (CR) units in Italy., Methods: The study was carried out using a web-based questionnaire running on the GICR-IACPR website for 4 weeks from September 2 to 29, 2013., Results: Out of 221 CR centers existing in Italy (+14% vs 2008), 191 (86%) participated in the survey. On a national basis, there is a CR unit every 268 852 inhabitants. The majority of CR units are located in public hospitals (57.1%), the remaining 42.9% in private hospitals; 130 CR centers (68%) provide inpatients care and account for 3527 beds (5.9 per 100 000 inhabitants): of these 374 are day-hospital beds and 408 are sub-intensive beds. Forty-one of the Italian in-hospital CR centers offer also outpatient programs and 61 centers (32%) offer only outpatient CR programs; 131 of the CR units (68.6%) are linked to dedicated cardiology divisions and in 77% of cases the head is a cardiologist. Home-based programs are offered by 9 centers (4.7%) and CR programs with telecare supervision by 16 (8.4%). Long-term secondary prevention follow-up programs are provided by 94 of CR services (49.2%). During one week of activity, the 191 centers completed 1335 inpatient CR programs and 971 outpatient CR programs. According to these data, it may be assumed that in Italy approximately 100 000 patients are referred annually to CR programs., Conclusions: ISYDE.13 showed an incremental trend of CR provision in Italy, particularly in outpatient programs. However, at present, the national network of CR units covers only one third of the potential requirements defined by current secondary prevention recommendations.

Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. First data on implementation of telemedicine for the diagnosis and treatment of acute myocardial infarction date from more than 10 years ago. Telemedicine has a potential broad application to the cardiovascular disease continuum and in many branches of cardiology, at least including heart failure, ischemic heart disease and arrhythmias. Telemedicine might have an important role as part of a strategy for the delivery of effective health care for patients with cardiovascular disease. In this document the Working Group on Telecardiology and Informatics of the Italian Society of Cardiology intends to remark some key-points regarding potential benefit achievable with the implementation of telemedicine support in the continuum of cardiovascular disease., (Copyright © 2015 Elsevier Ireland Ltd.

Background: Atrial fibrillation (AF) is associated with a high risk of stroke and other thrombo-embolic events and their prevention relies on antithrombotic therapy, at present mainly with vitamin K antagonists (VKA). The aim of this study was to provide an overall picture on the extent to which current recommendations on oral anticoagulation (OAC) therapy with VKA in AF correspond to actually prescribed OAC in an unselected, real world, population of consecutive patients with AF in Italy. Secondary objective was to assess the rate of "optimal" anticoagulation., Methods: Sixty-three cardiology units located in different geographic areas of Italy enrolled a total of 2046 outpatients with nonvalvular AF (54% males and 46% females, age 73.3±10.2 years)., Results: OAC with VKAs was prescribed in 1394 (68%) of patients and was progressively more frequent on going from paroxysmal (46%) to persistent (71%) and permanent AF (78%)(P<0.001). A high prescription rate (88%) occurred in patients with CHA2DS2-VASc >2. In patients with CHA2DS2-VASc=0 and HAS-BLED<3, still 59% were on OAC, whereas in 33% of patients with CHA2DS2-VASc ≥2 and HAS-BLED<3, OAC therapy was not prescribed. In patients with CHA2DS2-VASc ≥2 and HAS-BLED>3, the preference was towards OAC prescription. 66% of patients were at target for INR., Conclusions: The ISPAF study shows that in an Italian population of real world patients with AF adherence to current guidelines on OAC therapy based on stroke-risk scoring system is rather high, although rate of prescription should be increased. However, contrary to recommendations, in a high proportion of low-risk patients OAC therapy is still prescribed, and this might expose patients to unjustified risks., (© 2013.)

In 2003-2006, the distribution of macronutrients and pollutants of environmental interest was investigated in surficial sediments collected from 10 southern Italy harbors selected in four different regions. About 167 stations were sampled to determine levels of total organic carbon, total nitrogen, total phosphorous, trace elements (Al, Cd, Pb, Ni, Cr, Cu, Zn, Hg, As), short- and long-chain aliphatic hydrocarbons (Hy C > 12 and Hy C < 12), and concentrations of persistent organic pollutants (polychlorinated biphenyls, polycyclic aromatic hydrocarbons [PAHs], p-p-Dichlorodiphenyldichloroethylene (4,4'-DDE), and Hexachlorobenzene (HCB). General relationships between studied variables and harbors systems were explored by multivariate statistical approaches. Results show that wide fluctuations are reported for all variables both among harbors and inside each studied system. Principal components analysis suggests that major significance in explaining total average variability is due to lead, copper, zinc, silts, sands, and PAHs. No significance has been observed when testing nonmetric multidimensional scaling distributions relating with the factor "region," while performing analyses on factor "main human activity," a higher significance is observed. These results suggest a strong relationship between the main human use of marine systems and observed pollution levels in sediments.

Bacillus sp. ORAs2 and Pseudomonas sp. ORAs5, two arsenic-resistant bacterial strains previously isolated from sediments of the Orbetello Lagoon, Italy, were tested for their adaptation to mixed contaminants on the level of membrane fatty acid composition. The two bacterial strains were characterized by high levels of arsenic resistance, and Pseudomonas sp. ORAs5 was also shown to be solvent-tolerant. The bacterial strains were exposed to mixtures of two toxic compounds: arsenic at fixed concentrations and toluene in variable amounts or, alternatively, toluene at constant values along with arsenic added at variable concentrations. Both strains react to the contaminants by changing the composition of their membrane fatty acids. Bacillus sp. strain ORAs2 showed a correlation between growth rate decreases and fatty acids degree of saturation increases in both cases, although pointedly in the presence of 1, 2, and 3 mM of toluene and different additions of arsenic, counteracting membranes fluidity induced by toxic compounds. In Pseudomonas sp. ORAs5, adaptive changes in membrane composition was observed both in terms of increases in the degree of saturation and in the trans/cis ratio of unsaturated fatty acids in the presence of varying toluene and constant arsenic concentrations, whereas only minor changes occurred with increasing arsenic and constant toluene concentrations. Thus, on the level of membrane composition, Bacillus sp. ORAs2 showed a higher potential for adaptation to the presence of mixed pollutants, suggesting its probable suitability for bioremediation purposes.

Aims: The aim of this study was to isolate arsenic-resistant bacteria from contaminated sediment of the Orbetello Lagoon, Italy, to characterize isolates for As(III), As(V), heavy metals resistance, and from the phylogenetic point of view., Methods and Results: Enrichment cultures were carried out in the presence of 6.75 mmol l(-1) of As(III), allowing isolation of ten bacterial strains. Four isolates, ORAs1, ORAs2, ORAs5 and ORAs6, showed minimum inhibitory concentration values equal or superior to 16.68 mmol l(-1) and 133.47 mmol l(-1) in the presence of As(III) and As(V), respectively. Isolate ORAs2 showed values of 1.8 mmol l(-1) in the presence of Cd(II) and 7.7 mmol l(-1) of Zn(II), and isolate ORAs1 pointed out a value of 8.0 mmol l(-1) in the presence of Cu(II). Analysis of 16S rRNA gene sequences revealed that they can be grouped in the three genera Aeromonas, Bacillus and Pseudomonas. Phylogenetic analysis of the four more arsenic-resistant strains was also performed., Conclusion: Isolates are highly resistant to both As(III) and As(V) and they could represent good candidates for bioremediation processes of native polluted sediments., Significance and Impact of the Study: This study provides original results on levels of resistance to arsenic and to assigning genera of bacterial strains isolated from arsenic-polluted sediments.

Background: Atrial fibrillation (AF) is the most common sustained cardiac tachyarrhythmia and is often an occasional diagnosis in the absence of known cardiac disease. The aim of this study is to describe an Italian patient population with AF followed by their General Practitioners (GPs) using a telecardiology service., Methods: A total of 655 Italian GPs were equipped with a portable electrocardiographer. The ECG tracing of all consecutive patients (7516) received between January and September 2001 was included into the study., Results: AF was detected in 719 patients (9.%) (77+/-12 years). In 448 patients, it was a known chronic condition, while in 271 patients, it was a new diagnosis. In the chronic AF, the principal reason for the teleconsultation was a routine control by the GPs, but an uncontrolled cardiac rate was present in 29% of the cases, while an antiplatelet or anticoagulation therapy was administered in only 46.2% cases. The teleconsultation alone provided a solution to the GPs' requests in 348 patients (77.6%) (154 cases (34.5%) required no further action while 194 patients (43.5%) needed therapy adjustments only), while 47 patients (10.5%) required hospitalization and 51 patients needed further diagnostic tests. In 271 cases, a first evidence of atrial fibrillation was recorded: in 259 patients, GPs requested a teleconsultation in the presence of symptoms (mainly palpitation, dyspnoea and fatigue) and in 12 for routine control; in this case, 121 patients (46.9%) needed Emergency Department (ED) admission, 113 patients (39.1%) needed therapy adjustments and, for 19 patients (7.5%), further diagnostic tests were prescribed., Conclusion: In Italy, many patients, in particular the elderly, with AF are followed by their GPs on a routine basis; a telecardiology service may provide a useful tool in the home management of chronic AF and in the first detection of new cases of AF.

The use of telemedicine appears particularly promising in cardiovascular disease, because the cost/effectiveness ratio of an early, tailored intervention, in terms of life-saving and functional recovery is demonstrated. Boario Home Care project was born in 1998, with the aim of applying the new models of disease management and the new technology on the territory. In the first phase the project was to realize a telematic network for the General Practitioners in a mountain territory; In the second phase the project was extended to the regional and then national territory and the number of enrolled GPs increased. In the third phase, that is nowadays, the structure of the Service Center has been implemented with new broad band technologies (HDLS) and with an innovative teleworking model has been adopted for the professional figures involved. Four different types of services are now available: General Practitioners, Home Telenursing for chronic patients, Tele-diagnosis for palpitations and Call Center Services for hospitals. In conclusion, Boario Home Care project has reached its maturity and many results even if we can consider them preliminary in the field of Telemedicine. Boario Home Care project won e-health Awards with the honourable mention and it was presented at the "eHealth 2003: ICT for Health" in Brussels, Belgium.

Background: In chronic heart failure, several hormonal systems are activated with diagnostic and prognostic implications. We tested the hypotheses that serum Chromogranin-A (CgA) -- a 49 kDa acid protein present in the secretor granules of neuroendocrine cells -- is increased in chronic heart failure and that CgA levels are a predictive factor for mortality., Method and Results: In 160 patients with chronic heart failure, we measured serum CgA and other neuroendocrine hormones. The results showed that CgA is increased in chronic heart failure and the increase is related to the clinical severity of the syndrome: CgA levels in New York Heart Failure (NYHA) class II (median 146.9 ng x ml(-1), inter-quartiles 108.3-265.5) were significantly higher (P<0.05) than in class I (median 109.7 ng x ml(-1), inter-quartiles 96.7-137.6), and significantly lower (P<0.05) than in class III (median 279.0 ng x ml(-1), inter-quartiles 203.6-516.1). Class IV patients showed the highest serum levels of CgA (median 545.0 ng. ml(-1), inter-quartiles 231.8-1068.3), being statistically significantly different from class III patients (P<0.001). The association between survival and some recognized variables of prognostic significance, including CgA was also studied. The results showed that ejection fraction, noradrenaline, atrial natriuretic peptide, NYHA class and CgA were significant univariate prognosticators; however, in the multivariate analysis by the Cox proportional-hazard model, CgA and NYHA class were the only independent predictive factors for mortality (P<0.005, RR=1.22, 95% CI=1.06-1.41 and P=0.04, RR=1.58, 95% CI=1.02-2.46, respectively)., Conclusions: CgA is a pro-hormone, precursor of several active fragments likely to exert biological effects in chronic heart failure. CgA serum levels are increased in patients with chronic heart failure and are a predictive factor for mortality., (Copyright 2001 The European Society of Cardiology.)

Background: Rising health care costs resulted in increasing pressure on the health care system and stimulated new strategies for improving the efficiency of care. A telecardiology service provides a useful support to general practitioners in the management of cardiac patients and contributes to the optimization of health care costs in terms of appropriateness of hospital admission and diagnostic testing. The aim of our study was to evaluate the reduction in the number of referrals to the Emergency Department and to cardiological evaluation resulting from the employment of a telecardiology service by general practitioners., Methods: Eight hundred and ninety-one consecutive calls arrived to the receiving station of the telecardiology service were analyzed. One hundred and fifty general practitioners received a portable electrocardiographer (Card-Guard 7100, Rehovot, Israel) transferring, by a mobile or fixed telephone, a 12-lead ECG to a receiving station, where a cardiologist was available for reporting and for interactive teleconsultation. At the onset of the phone call, a question was asked to the general practitioner: "What would you have done without the telecardiology service?". The possible answers were: "No actions"; "Referral to the Emergency Department"; "Cardiological consultancy"; "Further investigations". Then we collected the history, risk factors, symptoms and therapy of the patients; the general practitioner sent the ECG tracing by phone., Results: Eight hundred and ninety-one patients were enrolled (402 males, 489 females, mean age 59 +/- 19 years); 465 (52%) patients were symptomatic; 36.4% had no evidence of previous cardiac disease, 35.1% had systemic hypertension, 10.6% had ischemic cardiac disease, 3.7% had atrial fibrillation, and 11.9% other diseases. ECG was normal in 55%. The general practitioners would have sent to the Emergency Department 106 patients (11.9%), and requested further investigations in 717 patients (80.5%). The cardiologist of the telecardiology service solved the problems of the general practitioners in 657 cases (73.7%), sent 56 patients (6.3%) to the Emergency Department, and asked for further investigations in 178 patients (20%), with a reduction of 47% of Emergency Department admission (p < 0.001) and of 95% of further investigations (p < 0.0001) respectively. The cost analysis showed a reduction, between the two modalities, varying from Itl 22,760,000 and Itl 140,060,000 for 891 calls., Conclusions: Telemedicine is a useful tool for the support of general practitioners' daily activity, with a possible cost reduction due to increased appropriateness of hospital admission and of diagnostic testing.
