Background: Multiple sclerosis (MS) is a complex disorder of the central nervous system whose cause is currently unknown. Evidence is increasing that DNA methylation alterations could be involved in inflammatory and neurodegenerative diseases and could contribute to MS pathogenesis. Repetitive elements Alu, LINE-1 and SAT-α, are widely known as estimators of global DNA methylation. We investigated Alu, LINE-1 and SAT-a methylation levels to evaluate their difference in a case-control setup and their role as a marker of disability. Results: We obtained blood samples from 51 MS patients and 137 healthy volunteers matched by gender, age and smoking. Methylation was assessed using bisulfite-PCR-pyrosequencing. For all participants, medical history, physical and neurological examinations and screening laboratory tests were collected. All repetitive elements were hypermethylated in MS patients compared to healthy controls. A lower Expanded Disability Status Scale (EDSS) score was associated with a lower levels of LINE-1 methylation for 'EDSS = 1.0' and '1.5 ≤ EDSS ≤ 2.5' compared to an EDSS higher than 3, while Alu was associated with a higher level of methylation in these groups: 'EDSS = 1.0' and '1.5 ≤ EDSS ≤ 2.5'. Conclusions: MS patients exhibit an hypermethylation in repetitive elements compared to healthy controls. Alu and LINE-1 were associated with degree of EDSS score. Forthcoming studies focusing on epigenetics and the multifactorial pathogenetic mechanism of MS could elucidate these links further. [ABSTRACT FROM AUTHOR]

The prognostic value of plasma renin activity (PRA) in chronic heart failure (HF) has been assessed before the widespread use of angiotensin-converting enzyme inhibitors (ACEi) and beta-blockers, which exert opposite effects on renin secretion. We evaluated the association between PRA and outcome in patients with chronic HF treated with ACEi and beta-blockers. [ABSTRACT FROM AUTHOR]

Abstract Exposure to ambient air particles matter (PM) has been associated with increased risk of lung cancer. Aberrant tumor suppressor gene promoter methylation has emerged as a promising biomarker for cancers, including lung cancer. Whether exposure to PM is associated with peripheral blood leukocyte (PBL) DNA methylation in tumor suppressor genes has not been evaluated. In 63 male healthy steel workers with well-characterized exposure to metal-rich particles nearby Brescia, Italy, we evaluated whether exposure to PM and metal components was associated with PBL DNA methylation in 4 tumor suppressor genes (i.e., APC, p16, p53 and RASSF1A). Blood samples were obtained on the 1st (baseline) and 4th day (post-exposure) of the same work week and DNA methylation was measured using pyrosequencing. A linear mixed model was used to examine the correlations of the exposure with promoter methylation levels. Mean promoter DNA methylation levels of APC or p16 were significantly higher in post-exposure samples compared to that in baseline samples (p-values = 0.005 for APC, and p-value = 0.006 for p16). By contrast, the mean levels of p53 or RASSF1A promoter methylation was decreased in post-exposure samples compared to that in baseline samples (p-value = 0.015 for p53; and p-value < 0.001 for RASSF1A). In post-exposure samples, APC methylation was positively associated with PM10 (β = 0.27, 95% CI: 0.13-0.40), and PM1 (β = 0.23, 95% CI: 0.09-0.38). In summary, ambient PM exposure was associated with PBL DNA methylation levels of tumor suppressor genes of APC, p16, p53 and RASSF1A, suggesting that such methylation alterations may reflect processes related to PM-induced lung carcinogenesis.

The EASY-NET network program (NET-2016-02364191)-effectiveness of audit and feedback (A&F) strategies to improve health practice and equity in various clinical and organizational settings), piloted a novel and more structured A&F strategy. This study compared the effectiveness of the novel strategy against the sole periodic dissemination of indicators in enhancing the appropriateness and timeliness of emergency health interventions for patients diagnosed with acute myocardial infarction (AMI) and ischemic stroke in the Lazio Region. The efficacy of the intervention was assessed through a prospective quasi-experimental design employing a pre- and post-intervention (2021-2022) comparison with a control group. Participating hospitals in the Lazio Region, where professional teams voluntarily engaged in the intervention, constituted the exposed group, while the control group exclusively engaged in routine reporting activities. Effectiveness analysis was conducted at the patient level, utilizing regional health information systems to compute process and outcome indicators. The effectiveness of the intervention was evaluated using difference-in-difference models, comparing pre- and post-intervention periods between exposed and control groups. Estimates were calculated in terms of the difference in percentage points (PP) between absolute risks. Sixteen facilities for the AMI pathway and thirteen for the stroke pathway participated in the intervention. The intervention yielded a reduction in the proportion of 30-day readmissions following hospitalization for ischemic stroke by 0.54 pp in the exposed patients demonstrating a significant difference of -3.80 pp (95% CI: -6.57; -1.03; 5453 patients, 63.7% cases) in the exposed group compared to controls. However, no statistically significant differences attributable to the implemented A&F intervention were observed in other indicators considered. These results represent the first evidence in Italy of the impact of A&F interventions in an emergency setting, utilizing aggregated data from hospitals involved in the Lazio Region's emergency network.

Background: Entering dialysis is a critical moment in patients' healthcare journey, and little is known about drug therapy around it. A study funded by the Italian Medicines Agency offered the opportunity to leverage data from the Lazio Regional Dialysis and Transplant Registry (RRDTL) and perform an observational study on drug use patterns before and after initiating chronic dialysis., Methods: Individuals initiating dialysis in 2016-2020 were identified from RRDTL, excluding patients with prior renal transplantation, stopping dialysis early, or dying within 12 months. Use of study drugs, predefined by clinicians, in the two years around the index date was retrieved from the drug claims register and described by semester. For each drug group, proportions of users (min 2 claims in 6 months) by semester, and intensity of treatment in terms of Defined Daily Doses (DDDs) for cardiovascular and antidiabetic agents were compared across semesters, stratifying by sex and age., Results: In our cohort of 3,882 patients we observed a general increase in drug use after initiating dialysis, with the mean number rising from 5.5 to 6.2. Cardiovascular agents accounted for the highest proportions, along with proton pump inhibitors and antithrombotics over all semesters. Dialysis-specific therapies showed the most evident increase, in particular anti-anaemics (iron 4-fold, erythropoietins almost 2-fold), anti-parathyroids (6-fold), and chelating agents (4-fold). Use of cardiovascular and antidiabetic drugs was characterised by significant variations in terms of patterns and intensity, with some differences between sexes and age groups., Conclusions: Entering dialysis is associated with increased use of specific drugs and goes along with adaptations of chronic therapies., (© 2024.

Within the EASY-NET network program (NET-2016-02364191), Work Package 1 Lazio evaluates the effectiveness of a structured audit and feedback (A&F) intervention compared with the web-based regional periodic publication of indicators in improving the appropriateness and timeliness of emergency healthcare for acute myocardial infarction (AMI). This work describes the A&F methodology and presents the results of the first feedback delivered. The intervention involves sending periodic reports via e-mail to participating hospitals. The feedback reports include a set of volume and quality (process and outcome) indicators, calculated by facility through the health information system of the Lazio Region and compared with regional mean, target values and values calculated for hospitals with similar volumes of activity. Health managers and clinicians of each participating hospital represent the "feedback recipients". They are invited to organize clinical and organizational audit meetings to identify possible critical issues in the care pathway and define, where necessary, improvement actions. A total of 16 facilities are involved. Twelve facilities present high volumes in all volume indicators, while three facilities present low volumes for each indicator. Concerning the quality indicators, four facilities do not present critical indicators or had average results, three facilities do not present critical indicators but show average results in at least one of the indicators and six facilities present a critical value for at least one of the indicators. The first report highlighted some critical issues in some facilities on several indicators. During the audit meetings, each facility analyzes these issues, defining appropriate improvement actions. The outcome of these actions will be monitored through subsequent reporting to support the continuous care quality improvement process.

Background: . In the last decades some studies observed a moderate progressive decrease in short-term mortality in incident hemodialysis patients. The aim of the study is to analyse the mortality trends in patients starting hemodialysis using the Lazio Regional Dialysis and Transplant Registry., Methods: . Patients who started chronic hemodialysis between 2008 and 2016 were included. Annual 1-year and 3-year Crude Mortality Rate*100 Person Years (CMR*100PY) overall, by gender and age classes were calculated. Cumulative survival estimates at 1 year and 3 years since the date of starting hemodialysis were presented as Kaplan-Meier curves for the three periods and compared using the log-rank test. The association between periods of incidence in hemodialysis and 1-year and 3-year mortality were investigated by means of unadjusted and adjusted Cox regression models. Potential determinants of both mortality outcomes were also investigated., Results: . Among 6,997 hemodialysis patients (64.5% males, 66.1% over 65 years old) 923 died within 1 year and 2,253 within 3 years form incidence; CMR*100PY were 14.1 (95%CI: 13.2-15.0) and 13.7 (95%CI: 13.2-14.3), respectively; both remained unchanged over the years. Even after stratification by gender and age classes no significant changes emerged. Kaplan-Meier mortality curves did not show any statistically significant differences in survival at 1 year and 3 years from hemodialysis incidence across periods. No statistically significant associations were found between periods and 1-year and 3-year mortality. Factors associated with a greater increase in mortality are: being over 65 years, born in Italy, not being self-sufficient, having systemic versus undetermined nephropathy, having heart disease, peripheral vascular disease, cancer, liver disease, dementia and psychiatric illness, and receiving dialysis by catheter rather than fistula., Conclusions: . The study shows that the mortality rate in patients with end-stage renal disease starting hemodialysis in the Lazio region was stable over 9 years., (© 2023. The Author(s).)

Background: Audit and Feedback (A&F) is one of the most common strategies used to improve quality in healthcare. However, there is still lack of awareness regarding the enabling factors and barriers that could influence its effectiveness. The aim of this study was to develop a questionnaire to measure the knowledge, attitudes and behaviors of general practitioners (GPs) regarding A&F. The study was performed in the context of the EASY-NET program (project code NET-2016-02364191)., Methods: The survey was developed according to two steps. Firstly, a scoping review was performed in order to map the literature on the existing similar instruments with the aim of identifying the sub-domains and possible items to include in a preliminary version of the questionnaire. In the second phase, the questionnaire was reviewed by a multidisciplinary group of experts and administrated to a convenience sample in a pilot survey., Results: Ten papers were included in the scoping review. The survey target and development methodology were heterogenous among the studies. The knowledge, attitudes and behaviors domains were assessed in six, nine and seven studies, respectively. In the first step, 126 pertinent items were extracted and categorized as follows: 8 investigated knowledge, 93 investigated attitudes, and 25 investigated behaviors. Then, 2 sub-domains were identified for knowledge, 14 for attitudes and 7 for behavior. Based on these results, a first version of the survey was developed via consensus among two authors and then revised by the multidisciplinary group of experts in the field of A&F. The final version of the survey included 36 items: 8 in the knowledge domain, 19 in the attitudes domain and 9 in the behaviors domain. The results of the pilot study among 15 GPs suggested a good acceptability and item relevance and accuracy, with positive answers totaling 100% and 93.3% in the proposed questions., Conclusions: The methodology used has shown to be a good strategy for the development of the survey. The survey will be administrated before and after the implementation of an A&F intervention to assess both baseline characteristics and changes after the intervention.

This article proposes a focus on Audit & Feedback (A&F)'s sustainability. If on one side, it is essential to ask how to bring A&F interventions out of research programs into clinical practices and contexts of care. On the other, it is fundamental to ensure that the experiences gained within care contexts can inform research, helping to define the research objectives and questions whose development can support paths of change. The reflection starts from two research programs on A&F carried out in the United Kingdom, respectively, at the regional level (Aspire) in the field of primary care and at the national level (Affinitie and Enact) in the field of the transfusion system. Aspire raised awareness of the importance of establishing a primary care implementation laboratory, which randomizes practices to different types of feedback to evaluate the effectiveness, also to improve patient care. The national Affinitie and Enact programs served to 'inform' recommendations to improve the conditions for sustainable collaboration between A&F researchers and audit programs. They represent an example to understand how to incorporate research results within a national clinical audit program. Finally, starting from the complex experience of the Easy-Net research program, the reflection moves on to how it was possible to make A&F interventions sustainable in Italy beyond research projects, in clinical-care contexts in which the resources provisions make continuous and structured interventions difficult and impractical. The Easy-Net program envisages different clinical care settings, study designs, interventions, and recipients, which require different actions to adapt research results to the specific realities to which A&F's interventions are addressed.

Background: A crucial step for planning effective public health policies for migrants with dementia is the collection of data on the local dimensions of the phenomenon and patients' characteristics., Objective: This study aimed to identify and characterize migrants with dementia in the Lazio region using health administrative databases., Methods: Residents with dementia aged 50 years or older, living in the Lazio region as of December 31, 2018, were identified using a validated algorithm based on hospital discharge(s), claims for antidementia drugs, and co-payment exemption for dementia. Migrants were defined as people born abroad and grouped in migrants from High Migratory Pressure Countries (HMPCs) and Highly Developed Countries (HDCs). Overall and age-specific prevalence rates were estimated in native- and foreign-born patients., Results: Dementia was ascertained in 38,460 residents. Among them, 37,280 (96.9%) were born in Italy, 337 (0.9%) were migrants from HDCs, and 843 (2.2%) from HMPCs. Dementia prevalence was higher among natives (1.15%, 95% CI 1.14-1.16) relative to migrants from HDCs (0.60%, 95% CI 0.54-0.67) and HMPCs (0.29%, 95% CI 0.27-0.31). The prevalence of comorbidities did not differ between groups. Migrants with dementia had a lower likelihood of receiving antidementia treatments compared with natives (51.6% in migrants from HDCs, 49.3% in migrants from HMPCs, and 53.5% among Italians)., Conclusion: Routinely collected data in healthcare administrative databases can support the identification of migrants with dementia. Migrants exhibited a lower age-standardized prevalence of registered dementia and lower access to dedicated treatments than Italians. These findings are suggestive of underdiagnosis and undertreatment of dementia in migrants.

Audit and Feedback (A&F) is an effective multidimensional strategy for improving the quality of care. The optimal methods for its implementation remain unclear. This study aimed to map the state of art of A&F strategies in the hospitals involved in a time-dependent emergency network. For these purposes, a structured questionnaire was defined and discussed within the research group. This consists of 29 questions in three sections: (1) characteristics of the structure, (2) internal feedback systems, and (3) external feedback systems. All structures involved in the network were invited to participate in the e-survey by indicating a Health Management representative and a clinical representative for the Cardiovascular (CaV) and/or for the Cerebrovascular area (CeV). Of 20 structures invited, a total of 13 (65%) responded to the survey, 11 for the CaV area and 8 for the CeV area. A total of 10 of 11 (91%) facilities for the CaV area and 8/11 (75%) for the CeV area reported that they perform A&F activities. All facilities perform at least one of the activities defined as "assimilating A&F procedures." The most frequent is the presentation and discussion of clinical cases (82% CaV and 88% CeV) and the least is the identification of responsible for improvement actions (45% CaV and 38% CeV). In 4/10 (40%) facilities for the CaV area and 4/8 (50%) for the CEV area, corrective actions are suggested or planned when the feedback is returned. These results confirm the need to define, in a synergistic way with the relevant stakeholders, an effective and agreed A&F intervention to improve the level of implementation of A&F strategies.

This article is the first of a series that aims to describe the Audit & Feedback (A&F) methodology. Some key elements focus on what A&F is and how it works. While it is an effective tool for promoting change in professional behaviour and improving the quality of care, there is still substantial uncertainty concerning how to implement A&F interventions to maximize its effects. The article explains how to design effective A&F on relevant issues, considering the available literature and direct experiences conducted in the National Health System (NHS). A&F interventions should aim to achieve clear, attainable, and evaluable objectives, which concern aspects of care for which there is solid evidence of literature and potential space for improvement. Based on data that measure any distance between what is expected and observed in local practice, the feedback must turn to those who can pursue the proposed change and who must trust the data collection and analysis process. Feedback should be provided more than once, in verbal and written form, and might include explicit objectives and an action plan. When planning A&F interventions, it is essential to provide specific data (e.g., aggregated at the level of a team, department, or individual doctor) rather than general, sending them directly to the professional or department involved rather than generically to the healthcare organization involved. In addition, it is essential to simplify the message so that the staff who receives the feedback can quickly understand the quality of the performance addressed and how to change it. Finally, it is necessary to encourage collaboration between the various healthcare professionals responsible for the quality of care and competence for improvement interventions (health professions, health management, quality expert personnel, and methodologists). Networking between staff improves the knowledge and effectiveness of A&F. This article finally proposes practical examples of two main aspects of A&F planning from the context of the EASY-NET program: how to increase the participation and involvement of the recipients of the intervention and the related pros and cons regarding the choice between the use of routinely available data from health information systems (SIS) and data collected ad hoc.

Background: Chronic kidney disease (CKD) is a common condition, characterized by high burden of comorbidities, mortality and costs. There is a need for developing and validating algorithm for the diagnosis of CKD based on administrative data. Methods: We validated our previously developed algorithm that used administrative data of the Lazio Region (central Italy) to define the presence of CKD on the basis of serum creatinine measurements performed between 2012 and 2015 at the Policlinico Gemelli Hospital. CKD and advanced CKD were defined according to eGFR (<60 and <30 mL/min/1.73 m2, respectively). Sensitivity, specificity, positive and negative predictive values (PPV/NPV) were computed. Results: During the time span of the study, 30,493 adult participants residing in the Lazio Region had undergone at least 2 serum creatinine measurements separated by at least 3 months. CKD and advanced CKD were present in 11.1% and 2.0% of the study population, respectively. The performance of the algorithm in the identification of CKD was high, with a sensitivity of 51.0%, specificity of 96.5%, PPV of 64.5% and NPV of 94.0%. Using advanced CKD, sensitivity was 62.9% (95% CI 59.0, 66.8), specificity 98.1%, PPV 40.4% and NPV 99.3%. Conclusion: The algorithm based on administrative data has high specificity and adequate performance for more advanced CKD; it can be used to obtain estimates of prevalence of CKD and to perform epidemiological research.

Evidence on social determinants of health on the risk of SARS-CoV-2 infection and adverse outcomes is still limited. Therefore, this work investigates educational disparities in the incidence of infection and mortality within 30 days of the onset of infection during 2020 in Rome, with particular attention to changes in socioeconomic inequalities over time. A cohort of 1,538,231 residents in Rome on 1 January 2020, aged 35+, followed from 1 March to 31 December 2020, were considered. Cumulative incidence and mortality rates by education were estimated. Multivariable log-binomial and Cox regression models were used to investigate educational disparities in the incidence of SARS-CoV-2 infection and mortality during the entire study period and in three phases of the pandemic. During 2020, there were 47,736 incident cases and 2281 deaths. The association between education and the incidence of infection changed over time. Till May 2020, low- and medium-educated individuals had a lower risk of infection than that of the highly educated. However, there was no evidence of an association between education and the incidence of SARS-CoV-2 infection during the summer. Lastly, low-educated adults had a 25% higher risk of infection from September to December than that of the highly educated. Similarly, there was substantial evidence of educational inequalities in mortality within 30 days of the onset of infection in the last term of 2020. In Rome, social inequalities in COVID-19 appeared in the last term of 2020, and they strengthen the need for monitoring inequalities emerging from this pandemic.

Background: A systematic examination of low-dose CT (LDCT) scan, beside lung nodules, may disclose the presence of undiagnosed diseases, improving the efficacy and the cost/efficacy of these programs. The study was aimed at evaluating the association between LDCT scan findings and non-oncologic and oncologic diseases., Methods: The LDCT scan of participants to the "Un Respiro per la vita" ® lung cancer screening program were checked and abnormal findings, beside lung nodules, recorded. First admission to the acute care because of cardiovascular (CD), respiratory (RD) and oncological diseases (OD) in the following three years were retrieved. The association of LDCT scan abnormal findings with CD, RD and OD was assessed through univariable and multivariable logistic regression models., Results: Mean age of 746 participants was 62 years (SD:5), 62% were male. 11 (1.5%) received a diagnosis of lung cancer. 16.1% participants were admitted to the acute care in the following three years: 8.6% for CD, 4.3% for RD and 5.2% for OD. Valve calcification (OR 2.02, p:0.02) and mucus plugs (OR 3.37, p:0.04) were positively associated with CD, while sub-pleural fibrosis had a protective role (OR 0.47, p:0.01). Lung nodules > 8 mm (OR 5.54, p: < 0.01), tracheal deviation (OR 6.04, p:0.01) and mucus plugs (OR 4.00, p:0.04) were positively associated with OD admissions. Centrilobular emphysema OR for RD admissions was 1.97 (p:0.06)., Conclusions: The observed association between selected LDCT findings and ensuing CD, RD and OD suggests that the information potential of LCDT goes beyond the screening of lung cancer., (© 2022.

Patients with end-stage kidney disease represent a frail population and might be at higher risk of SARS-CoV-2 infection. The Lazio Regional Dialysis and Transplant Registry collected information on dialysis patients with a positive swab. The study investigated incidence of SARS-CoV-2 infection, mortality and their potential associated factors in patients undergoing maintenance hemodialysis (MHD) in the Lazio region. Method: The occurrence of infection was assessed among MHD patients included in the RRDTL from 1 March to 30 November 2020. The adjusted cumulative incidence of infection and mortality risk within 30 days of infection onset were estimated. Logistic and Cox regression models were applied to identify factors associated with infection and mortality, respectively. Results: The MHD cohort counted 4942 patients; 256 (5.2%) had COVID-19. The adjusted cumulative incidence was 5.1%. Factors associated with infection included: being born abroad, educational level, cystic renal disease/familial nephropathy, vascular disease and being treated in a dialysis center located in Local Health Authority (LHA) Rome 2. Among infected patients, 59 (23.0%) died within 30 days; the adjusted mortality risk was 21.0%. Factors associated with 30-day mortality included: age, malnutrition and fever at the time of swab. Conclusions : Factors associated with infection seem to reflect socioeconomic conditions. Factors associated with mortality, in addition to age, are related to clinical characteristics and symptoms at the time of swab.

(1) Background: Interest in gender disparities in epidemiology, clinical features, prognosis and health care in chronic kidney disease patients is increasing. Aims of the study were to evaluate the association between gender and vascular access (arteriovenous fistula (AVF) or central venous catheter (CVC)) used at the start of hemodialysis (HD) and to investigate the association between gender and 1-year mortality. (2) Methods: The study includes 9068 adult chronic HD patients (64.7% males) registered in the Lazio Regional Dialysis Register (January 2008-December 2018). Multivariable logistic regression models were used to investigate the associations between gender and type of vascular access (AVF vs. CVC) and between gender and 1-year mortality. Interactions between gender and socio-demographic and clinical variables were tested adding the interaction terms in the final model. (3) Results: Females were older, had lower educational level and lower rate of self-sufficiency compared to males. Overall, CVC was used in 51.2% of patients. Females were less likely to use AVF for HD initiation than males. 1354 out of 8215 (16.5%) individuals died at the end of the follow-up period. Interaction term between gender and vascular access was significant in the adjusted model. From stratified analyses by vascular access, OR female vs. male (AVF) = 0.65; 95% CI 0.48-0.87 and OR female vs. male (CVC) = 0.88; 95% CI 0.75-1.04 were found. (4) Conclusions: This prospective population-based cohort study in a large Italian Region showed that in females starting chronic HD AVF was less common respect to men. The better 1-year survival of females is more evident among those women with AVF. Reducing gender disparity in access to AVF represents a key point in the management of HD patients.

Background: The factors associated with the inability to start hemodialysis with an arteriovenous fistula (AVF) in chronic kidney disease patients are not fully understood., Aim: Evaluating factors associated with type of vascular access at the first chronic hemodialysis and at 1 year after it., Methods: The study cohort includes patients registered in the Regional Dialysis and Transplant Registry of Lazio undergoing first hemodialysis between 2008 and 2015. Logistic regression models were used to evaluate the association between socio-demographic, clinical and care/organizational factors, and vascular access at first hemodialysis. Cox regression models were used to assess the odds of switching to AVF during the first year of hemodialysis among patients starting dialysis with central venous catheter (CVC)., Results: In the cohort of 6208 incident hemodialysis patients, 52.7% had an AVF and 47.3% had a CVC. Among the 2939 incident patients with CVC, 27.4% switched to FAV after 1 year. A higher probability of starting dialysis with AVF was observed among males (OR = 1.83; 95% CI 1.63-2.06), while a lower probability was observed among patients aged >85 years (OR 0.64; IC 95% 0.51-0.80). Patients with early referral to a nephrologist had a triple probability of start dialysis with AVF. We observed a higher odds of switch to AVF among males (HR = 1.62; 95% CI 1.40-1.89) and a lower odds among patients over 65 years., Conclusion: The observed high rate of AVF at the start of hemodialysis and of the switch from CVC to AVF in the first year, although declining since 2008, is a positive outcome. However, over one-third of patients maintain the CVC as vascular access for the first year because of unmodifiable factors, such as gender, age, comorbidity. The present study suggests that logistics/management and assistance/welfare problems may contribute to the delay or lack of AVF placement in incident hemodialysis patients or within the first year of dialysis.

Abstract: Guidelines for the treatment of rheumatoid arthritis (RA) recommend the use of conventional synthetic disease modifying anti-rheumatic drugs (cs-DMARDs) at the onset of the disease and only in the case of therapeutic failure, the addition of a biological drug (b-DMARD) is suggested.The study aimed to evaluate determinants for first-line biological treatment in patients with RA in clinical practice.A cohort of patients with RA, resident in Lazio, a central Italian Region, where Rome is located, and with at least one disease modifying anti-rheumatic drugs (DMARD) prescription between 2010 and 2016 was selected using health information systems linkable with each other by an individual unique anonymous identifier. In particular RA cohort was defined retrieving all patients with at least a RA disease code in regional data claims (hospital discharge, exemption code, emergency department access, or therapeutic plan). Only new users were included and the first-line treatment was identified: cs-DMARD or b-DMARD.Descriptive analysis according to type of DMARD treatment was performed. Through multivariate logistic regression models (odds ratio [OR]; confidence interval [CI95%]) determinants of therapy such as age, comorbidity, and comedication were investigated.Finally, switching during the first year of treatment from cs-DAMARDs to b-DMARDs was analyzed.DMARD-new users with RA were 5641; 7.1% of them with b-DMARD as first-line treatment. Considering the year of dispensing, this percentage ranged from 4.9% (2011) to 8.2% (2015). Among cs-DMARD the most prescribed active agent was methotrexate (59.3%), while among b-DMARD it was etarnecept (37.0%), followed by adalimumab (21.2%). The average age of the cohort was 54 years with 77% of women. Determinants of first-line b-DMARD use were: age (OR<30vs>65 = 3.7; 2.6-5.2, OR[30-45)vs>65 = 1.7; 1.2-2.4, OR[45-55)vs>65 = 1.6; 1.1-2.4, OR[55-65)vs>65 = 1.2; 0.8-1.7), cancers (OR = 2.3; 1.3-4.2), cardio-cerebrovascular disease (OR = 1.4; 1.0-1.9), use of non-steroidal anti-inflammatory drugs (NSAIDs) (OR = 0.6; 0.4-0.7) and corticosteroids (OR = 0.6; 0.5-0.7) in the 6 months preceding diagnosis.In the first year of treatment, we observed a percentage of switch from cs-DMARDs to b-DMARDs of 7.9%.In clinical practice, about 7% of patients with RA are prescribed with a b-DMARD as first-line treatment.

Background: Human exposure to air pollutants, and specifically to particulate matter (PM) and volatile organic compounds (VOCs), may pose a relevant risk on human health., Aim: To evaluate the personal exposure of adults living and working in Milan (Italy) by environmental and biological monitoring., Methods: Personal exposure of 51 volunteer adults to PM 2.5 , PM 2.5 - 10 and selected VOCs, including benzene, toluene, ethylbenzene, o-xylene, m + p-xylene, methyl tert-butyl ether, naphthalene, hexane, cyclohexane, heptane, and limonene was assessed along a 24-h period via personal cascade impactors and radial diffusive samplers. Urine spot samples were collected to investigate the corresponding urinary biomarkers. Time-activity patterns were filled in by participants to explore the performed activities. Multiple regression models were applied to investigate the association between personal exposure, biomarker levels, and tobacco smoke, traffic exposure, commuting mode, cooking activities, and personal characteristics., Results: Median personal exposure to PM 2.5 , PM 2.5 - , respectively. Median levels of urinary benzene, toluene, ethylbenzene o-xylene, m + p-xylene, naphthalene, hexane, and heptane were 78.0, 88.1, 21.5, 15.2, 43.9, 21.0, 11.0, and 22.5 ng/L, respectively. For personal exposure, multiple regression models explained up to 67% (PM 10 , benzene, toluene, ethylbenzene o-xylene, m + p-xylene, methyl tert-butyl ether, naphthalene, hexane, cyclohexane, heptane, and limonene were 36.1, 7.8, 2.3, 7.8, 2.1, 1.8, 4.7, 0.8, 0.3, 1.4, 2.5, 1.6, and 59.9 μg/m 3 , respectively. Median levels of urinary benzene, toluene, ethylbenzene o-xylene, m + p-xylene, naphthalene, hexane, and heptane were 78.0, 88.1, 21.5, 15.2, 43.9, 21.0, 11.0, and 22.5 ng/L, respectively. For personal exposure, multiple regression models explained up to 67% (PM 2.5 ) and 61% (benzene) of variability, with major contribution from commuting mode and environmental exposure. For biological monitoring, multiple regression analysis explained up to 74% of urinary benzene, with a major contribution given by creatinine, and secondary contributions by commuting mode, personal exposure to airborne benzene and smoking., Conclusions: Personal exposure to air pollutants was lower than that measured in the past in Milan. Personal exposure was mainly driven by traffic variables, while internal dose was mainly driven by personal characteristics and smoking habit., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

Background: the Covid-19 pandemic has provoked a huge of clinical and epidemiological research initiatives, especially in the most involved countries. However, this very large effort was characterized by several methodological weaknesses, both in the field of discovering effective treatments (with too many small and uncontrolled trials) and in the field of identifying preventable risks and prognostic factors (with too few large, representative and well-designed cohorts or case-control studies)., Objectives: in response to the fragmented and uncoordinated research production on Covid-19, the   italian Association of Epidemiology (AIE) stimulated the formation of a working group (WG) with the aims of identifying the most important gaps in knowledge and to propose a structured research agenda of clinical and epidemiological studies considered at high priority on Covid-19, including recommendations on the preferable methodology., Methods: the WG was composed by 25 subjects, mainly epidemiologists, statisticians, and other experts in specific fields, who have voluntarily agreed to the proposal. The agreement on a list of main research questions and on the structure of the specific documents to be produced were defined through few meetings and cycles of document exchanges., Results: twelve main research questions on Covid-19 were identified, covering aetiology, prognosis, interventions, follow-up and impact on general and specific populations (children, pregnant women). For each of them, a two-page form was developed, structured in: background, main topics, methods (with recommendations on preferred study design and warnings for bias prevention) and an essential bibliography., Conclusions: this research agenda represents an initial contribution to direct clinical and epidemiological research efforts on high priority topics with a focus on methodological aspects. Further development and refinements of this agenda by Public Health Authorities are encouraged.

Objectives: to investigate the association between real estate prices, education, and mortality., Design: cohort study., Setting and Participants: residents in Rome at the 2011 Italian Census, not living in institutions, and living in the address reported in the Census survey. People aged 18-99 years were followed from 2011 to 2016 using anonymous record linkage procedures with administrative databases. The Census includes several individual information, such as gender, age, education, residential neighbourhood. Data and cause of death were collected from mortality register. Real estate prices (euros/m2) were available for each neighbourhood., Main Outcome Measures: adjusted Cox regression models (hazard ratios - HRs and 95%CIs) were used to estimate the association among individual education, real estate price in the neighbourhood, and mortality., Results: the subjects selected were 2,051,376 (54% women, 22.5% with high education level). During the follow-up, 127,352 subjects died. Taking into account gender, age, marital status, and real estate prices, education level was strongly associated with all-cause mortality; compared to highly educated the higher mortality, risk was 35% (95%CI 32%-37%) for low education level and 16% (95%CI 14%-19%) for medium education level. Taking into account the same factors and education level, each increase of 1,000 euros in price/m2 was inversely associated with mortality (HR 0.96, 95%CI 0.96-0.97)., Conclusions: there is an independent association between the two indicators and mortality in Rome. A simple indicator such as real estate prices can be used to tackle inequalities.

We are presenting here the findings of the reaction to the COVID-19 epidemic during the period March to June 2020 of those centres participating in the research EASY-NET which is on-going in Italy, funded by the Ministry of Health and co-founded by the Regional Health Authorities. The objective of EASY-NET is to evaluate the effectiveness of the audit and feedback (A&F) strategies in different clinical and organizational settings in seven regions. As a negative consequence of the COVID-19 epidemic, the activities of the project have suddenly slowed down; nevertheless, the COVID-19 epidemic represented an opportunity to apply the A&F methodology and support the healthcare within the regional authorities in order to manage and monitor the impact of this new disease. The reaction to the crisis on behalf of EASY-NET was inconsistent across the participating regions for various reasons. Factors which influenced the reaction levels in relation to the rapidity and efficiency of the implementation of the A&F strategies were as follows: the varying epidemiological impact of the COVID-19 epidemic in the various territories, the different clinical and organizational context and availability of expert research teams together with A&F procedures which had already been tested before the start of the epidemic.

Objectives: Socioeconomic inequalities have a strong impact on population health all over the world. Occupational status is a powerful determinant of health in rich societies. We aimed at investigating the association between occupation and mortality in a large metropolitan study., Design: Cohort study., Setting: Rome, capital of Italy., Participants: We used the Rome Longitudinal Study, the administrative cohort of residents in Rome at the 2001 general census, followed until 2015. We selected residents aged 15-65 years at baseline. For each subject, we had information on sex, age and occupation (occupational status and type of job) according to the Italian General Census recognition., Main Outcome Measures: We investigated all-cause, cancer, cardiovascular and accidental mortality, major causes of death in the working-age population. We used Cox proportional hazards models to investigate the association between occupation and all-cause and cause-specific mortality in men and women., Results: We selected 1 466 726 subjects (52.1% women). 42 715 men and 29 915 women died during the follow-up. In men, 47.8% of deaths were due to cancer, 26.7% to cardiovascular causes and 6.4% to accidents, whereas in women 57.8% of deaths were due to cancer, 19.3% to cardiovascular causes and 3.5% to accidents. We found an association between occupational variables and mortality, more evident in men than in women. Compared with employed, unemployed had a higher risk of mortality for all causes with an HR=1.99 (95% CI 1.92 to 2.06) in men and an HR=1.49 (95% CI 1.39 to 1.60) in women. Compared with high-qualified non-manual workers, non-specialised manual workers had a higher mortality risk (HR=1.68, 95% CI 1.59 to 1.77 and HR=1.30, 95% CI 1.20 to 1.40, for men and women, respectively)., Conclusions: This study shows the importance of occupational variables as social health determinants and provides evidence for policy-makers on the necessity of integrated and preventive policies aimed at improving the safety of the living and the working environment., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Introduction: Due to the ongoing demographic and epidemiological transitions, estimating the phenomenon of dementia in migrants and minority groups, exploring its characteristics and challenges and implementing dedicated healthcare policies, constitute emerging and urgent matters for Western countries. In the present paper we describe the rationale and design of the 'Dementia in immigrants and ethnic minorities living in Italy: clinical-epidemiological aspects and public health perspectives" (ImmiDem) project., Methods and Analysis: Three main aims will be pursued by the ImmiDem project. First, a survey of all Italian dementia services will be conducted with dedicated questionnaires in order to estimate and describe the proportion and characteristics of migrants seeking help for cognitive disturbances. The different clinical approaches for diagnosing dementia and the challenges encountered in the assessment of cognitive functioning and in the provision of care in these groups of individuals will also be investigated. Second, record linkage procedures of data routinely collected in regional Health Information Systems will be conducted in order to identify and monitor migrant individuals with dementia living in the Lazio region. Third, tailored national and local care-coordination pathways and/or good practices dedicated to migrants affected by dementia and cognitive disorders will be identified and promoted., Ethics and Dissemination: The study protocol was approved by the Ethics Committee of the Italian National Institute of Health (protocol 10749; 5 April 2018). The project was launched in November 2018 and will end in November 2021. The findings of the project will be disseminated through scientific peer-reviewed journals as well as to the public via the Dementia Observatory website (https://demenze.iss.it)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background/objectives: The pathologic relationship linking obesity and lipid dismetabolism with earlier onset of aging-related disorders, including cardiovascular disease (CVD) and type-2 diabetes (T2D), is not fully elucidate. Chronic inflammatory state, in obese individuals, may accelerate cellular aging. However, leukocyte telomere length (LTL), the cellular biological aging indicator, is elusively linked with obesity. Recent studies indicate that sterol 27-hydroxylase (CYP27A1) is an emerging antiatherogenic enzyme, that, by converting extrahepatic cholesterol to 27-hydroxycholesterol, facilitates cholesterol removal via high-density lipoprotein-cholesterol (HDL-C). We tested the hypothesis that obese subjects who carry at least three copies of CYP27A1 low-hydroxylation (LH) activity genome-wide-validated alleles (rs4674345A, rs1554622A, and rs4674338G) present premature aging, as reflected in shorter LTL and higher levels of CVD/T2D risk factors, including reduced HDL-C., Subjects/methods: Obese subjects from SPHERE project { n  = 1,457; overweight [body mass index (BMI) 25-30 kg/m 2 ] 65.8% and severe-obese (BMI > 30 kg/m 2 ) 34.2%} were characterized for the presence from 0 to 6 LH-CYP27A1 allele copy number. Univariate and multivariable sex-age-smoking-adjusted linear-regression models were performed to compare CVD/T2D risk factors and biological aging (LTL) in relation to the combined BMI-LH groups: overweight-LH: 0-2, overweight-LH: 3-6, severe-obese-LH: 0-2, and severe-obese-LH: 3-6., Results: Higher LTL attrition was found in severe-obese than overweight individuals ( p  < 0.001). Multivariable model reveals that among severe-obese patients those with LH: 3-6 present higher LTL attrition than LH: 0-2 ( p  < 0.05). Univariate and multivariable models remarkably show that insulin resistance is higher both in overweight-LH: 3-6 vs overweight-LH: 0-2 ( p  < 0.001) and in severe-obese-LH: 3-6 vs severe-obese-LH: 0-2 ( p  < 0.0001), and HDL-C is lower in overweight-LH: 3-6 than overweight-LH: 0-2 ( p  < 0.05 and p  < 001). Finally, most of the well-known (i.e., blood pressure, heart rate, waist to hip, triglycerides, and HDL-C) and novel CVD risk factors [i.e., inflammation markers (C-reactive protein, leukocytes, and chemoattractant protein-1), fibrinogen, and glucose homeostasis (i.e., insulin resistance, and glycated hemoglobin)] are substantially ( p  < 0.0001) altered in severe-obese-LH: 0-2 vs overweight-LH: 0-2, pointing to the fact that obesity leads to worsen the CVD/T2D risk factor profile., Conclusion: Our study supports evidence that CYP27A1 genetic characterization identifies persons at higher risk to develop CVD and T2D, on which better converge preventive measures, and opens new perspectives on mechanisms that link obesity with aging-related disorders.
