Hepatitis C epidemiology and treatment outcomes in Italy: Impact of the DAA era and the COVID-19 pandemic.

HCV infection poses a global health threat, with significant morbidity and mortality. This study examines HCV trends in a large Italian region from 2015 to 2022, considering demographic changes, evolving clinical profiles, treatment regimens and outcomes, including the impact of the COVID-19 pandemic. This multicentre retrospective study analysed demographics, clinical histories and risk factors in 6882 HCV patients. The study spanned before and after the direct-acting antiviral (DAA) era, and the COVID-19 period, focusing on treatment outcomes (SVR12, non-SVR12 and patients lost to follow-up). Statistical methods included ANOVA, multinomial logistic regression, Kruskal-Wallis test and chi-square analysis, and were conducted adhering to the intention-to-treat (ITT) principle. The cohort, mainly Italian males (average age 58.88), showed Genotype 1 dominance (56.6%) and a high SVR12 rate (97.5%). The pandemic increased follow-up losses, yet SVR12 rates remained stable, influenced by factors like age, gender, cirrhosis and comorbidities. Despite COVID-19 challenges, the region sustained high SVR12 rates in HCV care, emphasising the importance of sustained efforts in HCV care. Continuous screening and targeted interventions in high-risk populations are crucial for achieving WHO elimination targets. The study highlights the resilience of HCV care during the pandemic and provides insights for future public health strategies.

Evaluating hepatitis C cascade of care surveillance system in Tuscany, Italy, through a population retrospective data-linkage study, 2015-2021.

This comprehensive retrospective data-linkage study aimed at evaluating the impact of Direct-Acting Antivirals (DAAs) on Hepatitis C Virus (HCV) testing, treatment trends, and access to care in Tuscany over six years following their introduction. Utilizing administrative healthcare records, our work reveals a substantial increase in HCV tests in 2017, attributed to the decision to provide universal access to treatment. However, despite efforts to eradicate chronic HCV through a government-led plan, the target of treating 6,221 patients annually was not met, and services contracted after 2018, exacerbated by the COVID-19 pandemic. Key findings indicate a higher prevalence of HCV screening among females in the 33-53 age group, influenced by pregnancy-related recommendations, while diagnostic tests and treatment uptake were more common among males. Problematic substance users constituted a significant proportion of those tested and treated, emphasizing their priority in HCV screening. Our paper underscores the need for decentralized HCV models and alternative testing strategies, such as point-of-care assays, especially in populations accessing harm reduction services, communities, and prisons. The study acknowledges limitations in relying solely on administrative records, advocating for improved data access and timely linkages to accurately monitor HCV care cascades and inform regional plans. Despite challenges, the paper demonstrates the value of administrative record linkages in understanding the access to care pathway for hard-to-reach populations. The findings emphasize the importance of the national HCV elimination strategy and the need for enhanced data collection to assess progress accurately, providing insights for future regional and national interventions.

Vaccines and vaccination in prison settings: availability and model of service delivery in 20 European countries.

Prisons, due to various risk factors, are environments that are conducive to infectious disease transmission, with significantly higher prevalence of infectious diseases within prisons compared to the general population. This underscores the importance of preventive measures, particularly vaccination. As part of the international project "Reaching the hard-to-reach: Increasing access and vaccine uptake among the prison population in Europe" (RISE-Vac), this study aimed to map the availability and delivery framework of vaccination services in prisons across Europe and beyond. A questionnaire designed to collect data on the availability and delivery model of vaccination services in prisons was validated and uploaded in SurveyMonkey in July 2023. Then, it was submitted to potential participants, with at least one representative from each European country. Potential participants emailed an invitation letter by the RISE-Vac partners and by the European Organization of Prison and Correctional Services (EUROPRIS). Twenty European countries responded. Vaccines are available in European countries, although their availability differs by country and type of vaccine. The first dose is offered to people living in prisons (PLP), mostly within one month, COVID-19 is the most widely offered vaccine. In all countries, vaccines are actively offered by healthcare workers; in most countries, there is no evaluation of vaccination status among people who work in prison. The survey shows variance in vaccine availability for PLP and staff across countries and vaccine types. Quality healthcare in prisons is not only a matter of the right to health but also a critical public health investment: enhancing vaccine uptake consistently among PLP and staff should be prioritized.

Implementation of COVID-19 vaccination services in prison in six European countries: translating emergency intervention into routine life-course vaccination.

BACKGROUND: Evidence has shown that the risk of transmission of SARS-CoV-2 is much higher in prisons than in the community. The release of the COVID-19 vaccine and the recommendation by WHO to include prisons among priority settings have led to the inclusion of prisons in national COVID-19 vaccination strategies. Evidence on prison health and healthcare services provision is limited and often focuses on a single country or institution due to the multiple challenges of conducting research in prison settings. The present study was done in the framework of the EU-founded project RISE-Vac. It aimed to analyse the best practices and challenges applied in implementing COVID-19 universal vaccination services during the pandemic to support future expansion of routine life course vaccination services for people living in prison (PLP). METHODS: Two online cross-sectional surveys were designed and piloted: survey1 on prison characteristics and (non-COVID-19) immunisation practices; survey2 on the implementation and coverage of COVID-19 vaccination with open-ended questions for thematic analysis. Each RISE-Vac project partner distributed the questionnaire to one or two prisons in their country. Answers were collected from eight European prisons' directors or medical directors between November 2021-May 2022. RESULTS: According to our findings, the implementation modalities of COVID-19 vaccination services in the surveyed prisons were effective in improving PLP vaccination coverage. Strategies for optimal management of the vaccination campaign included: periodic time slot for PLP vaccination; new staff recruitment and task shifting; distribution of informational material both to PLP and prison staff. Key challenges included continuity of care after release, immunisation information system, and vaccine hesitancy. CONCLUSIONS: To the best of our knowledge, this is the first study describing the implementation of COVID-19 vaccination services in European prisons, suggesting that the expansion of vaccination provision in prison is possible. There is no unique solution that will fit every country but commonalities likely to be important in the design and implementation of future vaccination campaigns targeting PLP emerged. Increased availability of vaccination services in prison is not only possible, but feasible and highly desirable, and can contribute to the reduction of health inequalities.

[The peer-review process: critical issues and challenges from an online survey]. / Il processo della revisione tra pari: criticità e sfide emerse da una survey online.

BACKGROUND: the peer-review process, which is the foundation of modern scientific production, represents one of its essential elements. However, despite numerous benefits, it presents several critical issues. OBJECTIVES: to collect the opinions of a group of researchers from the epidemiological scientific community on peer-review processes. DESIGN: cross-sectional study using a questionnaire evaluation. SETTING AND PARTICIPANTS: a 29-question survey was administered to 516 healthcare professionals through the SurveyMonkey platform. The questions focused on the individual characteristics of the respondents and their perceived satisfaction with some characteristics of the review process as well as their propensity of changing some aspects of it. In addition, three open-ended questions were included, allowing respondents to provide comments on the role that reviewers and the review process should play. Descriptive statistics were produced in terms of absolute frequencies and percentages for the information collected through the questionnaire. Secondly, a multiple logistic regression analysis was conducted to assess the willingness to change certain aspects of peer review, adjusting for covariates such as age, sex, being the author of at least one scientific work, being a reviewer of at least one scientific work, and belonging to a specific discipline. The results are expressed as odds ratios (ORs) and their 95% confidence intervals (95%CI). Text analysis and representation using word cloud were also used for an open-ended question. MAIN OUTCOMES MEASURES: level of satisfaction regarding some characteristics of the peer-review process. RESULTS: a total of 516 participants completed the questionnaire. Specifically, 87.2% (N. 450) of the participants were the authors of at least one scientific publication, 78.7% were first authors at least once (N. 406), and 71.5% acted as reviewers within the peer-review process (N. 369). The results obtained from the multiple logistic regression models did not highlight any significant differences in terms of propensity to change for age and sex categories, except for a lower propensity of the under 35 age group towards unmasking, defined as the presence of reviewers and editorial boards names on the publish article (OR <35 years vs 45-54 years: 0.51; 95%CI 0.29-0.89) and a higher propensity for post-formatting proposals, defined as the possibility of formatting the article following journal guidelines after the acceptance, among those under 45 (OR <35 years vs 45-54 years: 1.73; 95%CI 0.90-3.31; OR 35-44 years vs 45-54 years: 2.02; 95%CI 1.10-3.72). Finally, approximately 50% of respondents found it appropriate to receive credits for the revision work performed, while approximately 30% found it appropriate to receive a discount on publication fees for the same journal in which they acted as reviewers. CONCLUSIONS: the peer-review process is considered essential, but imperfect, by the professionals who participated in the questionnaire, thus providing a clear picture of the value that peer-review adds rigorously to each scientific work and the need to continue constructive dialogue on this topic within the scientific community.

[Italian Association of Epidemiology: How has the demographic, educational, and occupational profile of members changed in recent years]. / Associazione Italiana di Epidemiologia: com'è cambiato il profilo demografico, formativo e occupazionale dei soci e delle socie negli ultimi anni.

In recent years, the number of members of the Italian Association of Epidemiology (AIE) has increased considerably, and their profile has undergone many changes. The aim of this work is to describe the characteristics of the members, with particular attention to those who have been continuously enrolled. To evaluate these characteristics, the data from membership forms submitted to the Association and information available on the new website in the personal profile area (period 2016-2024) were used. The characteristics considered were: gender, age, education, and job position of the member, Region, and type of affiliated institution. Members with at least three registrations during the period considered, including at least one in the last three years (2022-2024), are considered continuous members.In 2024, AIE counts 557 members, of whom 340 (61.0%) are female and 182 (32.7%) are under 35 years old. This data confirms the growing trend observed since 2015, when the number of members was just above 300, considering that each year there is a quota of new members amounting to about 30%. A total of 382 members can be considered continuous. Over 90% of these members work in 8 Regions (Lazio, Piedmont, Emilia-Romagna, Lombardy, Tuscany, Veneto, Puglia, and Sicily), while the other regions are scarcely or not represented at all. Over time, and with the arrival of new members, the Association is shifting towards the academic world, while the proportion of professionals working in public health institutions has decreased. Members are overall highly educated; however, while older cohorts have predominantly a medical and biological education, younger cohorts increasingly have statistical/mathematical education. Seventy percent of the members have a permanent contract, 5% have a fixed-term contract, and 13% have an atypical contract. Precarious contracts tend to be lower among medical graduates and remain higher in other health professions and non-health-related degrees.AIE is dealing with a period of dynamism and openness, marked by the increase in the number of the members and the transformation of their occupational and educational profile. It is crucial to support and promote the ongoing positive changes, such as the wider geographic representativeness and the entry of new recruits, also facilitated by multiple activities carried out by AIE, including congresses, working groups, webinars, training courses, and collaborations with other scientific societies. At the same time, it might be useful to open a discussion on the meaning and consequences of the increase of academic members and the reduction, at least in relative terms, of individuals coming from public health. Finally, it will be necessary to approach some critical issues, such as the still poor multidisciplinarity and the persistence of job insecurity, especially among graduates in educational pathways that still do not fit into the professional profiles recognized by the NHS.

Modulation of synapse-related gene expression in the cerebellum and prefrontal cortex of rats subjected to the contextual fear conditioning paradigm.

The contextual fear conditioning (CFC) paradigm is the most productive approach for understanding the neurobiology of learning and memory as it allows to follow the evolution of memory traces of a conditioned stimulus and a specific context. The formation of long-term memory involves alterations in synaptic efficacy and neural transmission. It is known that the prefrontal cortex (PFC) exerts top-down control over subcortical structures to regulate behavioural responses. Moreover, cerebellar structures are involved in storing conditioned responses. The purpose of this research was to determine if the response to conditioning and stressful challenge is associated with alterations in synapse-related genes mRNA levels in the PFC, cerebellar vermis (V), and hemispheres (H) of young adult male rats. Four groups of Wistar rats were examined: naïve, CFC, shock only (SO), and exploration (EXPL). The behavioural response was evaluated by measuring the total freezing duration. Real-Time PCR was employed to quantify mRNA levels of some genes involved in synaptic plasticity. The results obtained from this study showed alterations in gene expression in different synapse-related genes after exposure to stressful stimuli and positioning to new environment. In conclusion, conditioning behavioural stimuli change the expression profile of molecules involved in neural transmission.

Long-term exposure to low-level arsenic in drinking water is associated with cause-specific mortality and hospitalization in the Mt. Amiata area (Tuscany, Italy).

BACKGROUND: Arsenic in drinking water is a global public health concern. This study aims to investigate the association between chronic low-level exposure to arsenic in drinking water and health outcomes in the volcanic area of Mt. Amiata in Italy, using a residential cohort study design. METHODS: Chronic exposure to arsenic in drinking water was evaluated using monitoring data collected by the water supplier. A time-weighted average arsenic exposure was estimated for the period 2005-2010. The population-based cohort included people living in five municipalities in the Mt. Amiata area between 01/01/1998 and 31/12/2019. Residence addresses were georeferenced and each subject was matched with arsenic exposure and socio-economic status. Mortality and hospital discharge data were selected from administrative health databases. Cox proportional hazard models were used to test the associations between arsenic exposure and outcomes, with age as the temporal axis and adjusting for gender, socio-economic status and calendar period. RESULTS: The residential cohort was composed of 30,910 subjects for a total of 407,213 person-years. Analyses reported risk increases associated with exposure to arsenic concentrations in drinking water > 10 µg/l for non-accidental mortality (HR = 1.07 95%CI:1.01-1.13) and malignant neoplasms in women (HR = 1.14 95%CI:0.97-1.35). Long-term exposure to arsenic concentrations > 10 µg/l resulted positively associated with several hospitalization outcomes: non-accidental causes (HR = 1.06 95%CI:1.03-1.09), malignant neoplasms (HR = 1.10 95%CI:1.02-1.19), lung cancer (HR = 1.85 95%CI:1.14-3.02) and breast cancer (HR = 1.23 95%CI:0.99-1.51), endocrine disorders (HR = 1.13 95%CI:1.02-1.26), cardiovascular (HR = 1.12 95%CI:1.06-1.18) and respiratory diseases (HR = 1.10 95%CI:1.03-1.18). Some risk excesses were also observed for an exposure to arsenic levels below the regulatory standard, with evidence of exposure-related trends. CONCLUSIONS: Our population-based cohort study in the volcanic area of Mt. Amiata showed that chronic exposure to arsenic concentrations in drinking water above the current regulatory limit was associated with a plurality of outcomes, in terms of both mortality and hospitalization. Moreover, some signs of associations emerge even at very low levels of exposure, ​​below the current regulatory limit, highlighting the need to monitor arsenic concentrations continuously and implement policies to reduce concentrations in the environment as far as possible.

Potential effects of Alliaceae and Brassicaceae edible plants on blood glucose levels in patients with type 2 diabetes: A systematic review and meta-analysis of clinical trials.

Type 2 diabetes (T2D) is one of the main leading causes of mortality worldwide, and its global prevalence will increase within the next years. Many pre-clinical studies demonstrated the potential effects of edible plants from Alliaceae and Brassicaceae on the regulation of blood glucose levels. Of note, secondary metabolites from Alliaceae and Brassicaceae share the ability to slowly release hydrogen sulfide (H2S), which is emerging as a crucial modulator of the "glucose-insulin system". However, the results of clinical studies evaluating the effects of such edible plants on glycaemic control in patients with T2D are quite conflicting. We performed a systematic review and meta-analysis of controlled clinical trials, both parallel and cross-over, searching four databases (Pubmed, Embase, Scopus and the Cochrane library). Only English-written papers evaluating the effects of Alliaceae and Brassicaceae on glycaemic parameters in diabetic patients have been included. 16 studies met the inclusion criteria, and 12 were included in the random-effects meta-analysis. Consumption of Alliaceae or Brassicaceae significantly reduced fasting blood glucose (FBG) levels compared with the placebo group (mean reduction: -12.67 mg/dl [95% confidence interval (CI) - 19.66; - 5.68]). Moreover, Alliaceae and Brassicaceae significantly improved the effects of standard antidiabetic therapy (mean reduction in FBG levels in patients receiving combination therapy compared with patients only receiving standard antidiabetic therapy: -6.75 mg/dl [-12.62; -0.88]). Overall, the regular consumption of these edible plants was safe and well-tolerated. We suggest that edible plants containing organosulfur compounds are endowed with promising nutraceutical potential in the treatment of T2D.

Health effects associated with short-term exposure to hydrogen sulfide from geothermal power plants: a case-crossover study in the geothermal areas in Tuscany.

OBJECTIVE: Thirty-four geothermal power plants for the production of electricity are currently active in the geothermal areas in Tuscany. The present study aimed to investigate the association between short-term exposure to hydrogen sulfide (H2S) and acute health outcomes. METHODS: This study used individual data on non-accidental, cardiovascular and respiratory mortality, urgent hospital admissions (HA) and emergency department (ED) visits for cardiorespiratory diseases occurring from 2000 to 2017. All cases were georeferenced and matched to daily H2S data, derived from 18 monitoring sites. A case-crossover design following the matched pair interval approach was applied and conditional logistic regression models were fitted to estimate odds ratios and their 90% confidence intervals, adjusting for a set of time-dependent variables, such as influenza epidemics, holidays and temperature. RESULTS: A total of 8054 deaths, 30,527 HA and 15,263 ED visits occurred. Mortality for non-accidental (OR = 1.11, 90% CI 1.02-1.22) and cardiovascular causes (OR = 1.22, 90% CI 1.03-1.44) were associated with an increase of 10 µg/m3 of H2S daily levels only among men. Hospital admissions for respiratory diseases were positively associated with H2S exposure: OR = 1.11 (90% CI 1.00-1.22) among women. No associations were observed in ED visits analyses. CONCLUSIONS: In this case-crossover study in the Tuscan geothermal areas, short-term exposure to H2S was weakly associated with some mortality and morbidity outcomes. Our findings did not show a clear pattern as the results were not homogeneous between mortality and morbidity data or between men and women.

Vaccination against emerging and reemerging infectious diseases in places of detention: a global multistage scoping review.

Background: Despite the elevated risks of infection transmission, people in prisons frequently encounter significant barriers in accessing essential healthcare services in many countries. The present scoping review aimed to evaluate the state of availability and model of delivery of vaccination services within correctional facilities across the globe. Methods: Following the methodological framework for scoping reviews and adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews criteria, we conducted a systematic search across four peer-reviewed literature databases (Medline via PubMed, Web of Science, the Cochrane Library, Science Direct, and EBSCO), as well as 14 sources of grey literature. Two researchers meticulously examined the identified papers independently to extract pertinent data published between 2012 and 2022. The quality of the selected publications was assessed using established quality assessment tools. Results: Of the 11,281 identified papers 52 met the inclusion criteria. With the exception of one, all the included publications presented data from high-income countries, predominantly originating from the United States. Across the world, the most prevalent vaccines available in prison settings were COVID-19 and HBV vaccines, typically distributed in response to health crises such as pandemics, epidemics, and local outbreaks. Vaccine coverage and uptake rates within correctional facilities displayed noteworthy disparities among various countries and regions. Besides, individual and organizational barriers and facilitating factors of vaccination in prison settings emerged and discussed in the text. Discussion: The lack of vaccination services combined with low rates of vaccination coverage and uptake among people living and working in correctional facilities represents a cause for concern. Prisons are not isolated from the broader community, therefore, efforts to increase vaccine uptake among people who live and work in prisons will yield broader public health benefits.

Integrated environmental and clinical surveillance for the prevention of acute respiratory infections (ARIs) in indoor environments and vulnerable communities (Stell-ARI): Protocol.

The epidemiological relevance of viral acute respiratory infections (ARIs) has been dramatically highlighted by COVID-19. However, other viruses cannot be neglected, such as influenza virus, respiratory syncytial virus, human adenovirus. These viruses thrive in closed spaces, influenced by human and environmental factors. High-risk closed communities are the most vulnerable settings, where the real extent of viral ARIs is often difficult to evaluate, due to the natural disease progression and case identification complexities. During the COVID-19 pandemic, wastewater-based epidemiology has demonstrated its great potential for monitoring the circulation and evolution of the virus in the environment. The "Prevention of ARIs in indoor environments and vulnerable communities" study (Stell-ARI) addresses the urgent need for integrated surveillance and early detection of ARIs within enclosed and vulnerable communities such as long-term care facilities, prisons and primary schools. The rapid transmission of ARIs in such environments underscores the importance of comprehensive surveillance strategies to minimise the risk of outbreaks and safeguard community health, enabling proactive prevention and control strategies to protect the health of vulnerable populations. This study consists of designing and validating tools for integrated clinical and environmental-based surveillance for each setting, coupled with analytical methods for environmental matrices. The clinical surveillance involves specialized questionnaires and nasopharyngeal swabs for virus identification, while the environmental surveillance includes air and surface microbiological and chemical monitoring, and virological analysis of wastewater. Integrating this information and the collection of behavioural and environmental risk factors into predictive and risk assessment models will provide a useful tool for early warning, risk assessment and informed decision-making. The study aims to integrate clinical, behavioural, and environmental data to establish and validate a predictive model and risk assessment tool for the early warning and risk management of viral ARIs in closed and vulnerable communities prior to the onset of an outbreak.

[Evidence synthesis 2.0: how artificial intelligence is making systematic reviews more efficient.] / La sintesi delle evidenze 2.0: come l'intelligenza artificiale sta rendendo più efficienti le revisioni sistematiche.

Systematic reviews (SRs) are essential tools for synthesising the available scientific evidence on a given topic, and in some healthcare fields they represent the core for public health decisions according to the principles of evidence-based medicine. However, keeping up to date with the volume of scientific production is not always easy given the estimated annual increase in scientific publications of 4.10%. Indeed, SRs take a long time, with an average time of eleven months from design to submission to a scientific journal; to make more efficient this process and timely achieve evidence collection, systems such as living systematic reviews and artificial intelligence tools have been developed for the automation of SRs. These tools can be divided into three categories: visualisation tools, active learning tools and automated tools with Natural Language Processing (NLP). Nlp makes it possible to reduce the time spent and human error, for example, in the screening of primary studies; there are already many tools that apply to all stages of a SR, currently the most widely used are those with "human-in-the-loop" where the reviewer is involved in the various steps to verify the goodness of the work performed by the model. At this time of transition in SRs, new approaches are emerging and are increasingly appreciated by the community of reviewers; leaving some more basic but also error-prone tasks to machine learning tools can increase the efficiency of the reviewer and the overall quality of the review itself.

Adherence to Oral Antidiabetic Drugs in Patients with Type 2 Diabetes: Systematic Review and Meta-Analysis.

Poor adherence to oral antidiabetic drugs (OADs) in patients with type 2 diabetes (T2D) can lead to therapy failure and risk of complications. The aim of this study was to produce an adherence proportion to OADs and estimate the association between good adherence and good glycemic control in patients with T2D. We searched in MEDLINE, Scopus, and CENTRAL databases to find observational studies on therapeutic adherence in OAD users. We calculated the proportion of adherent patients to the total number of participants for each study and pooled study-specific adherence proportions using random effect models with Freeman-Tukey transformation. We also calculated the odds ratio (OR) of having good glycemic control and good adherence and pooled study-specific OR with the generic inverse variance method. A total of 156 studies (10,041,928 patients) were included in the systematic review and meta-analysis. The pooled proportion of adherent patients was 54% (95% confidence interval, CI: 51-58%). We observed a significant association between good glycemic control and good adherence (OR: 1.33; 95% CI: 1.17-1.51). This study demonstrated that adherence to OADs in patients with T2D is sub-optimal. Improving therapeutic adherence through health-promoting programs and prescription of personalized therapies could be an effective strategy to reduce the risk of complications.

Levels and determinants of urinary and blood metals in the geothermal area of Mt. Amiata in Tuscany (Italy).

Natural sources and anthropogenic activities are responsible for the widespread presence of heavy metals in the environment in the volcanic and geothermal area of Mt. Amiata (Tuscany, Italy). This study evaluates the extent of the population exposure to metals and describes the major individual and environmental determinants. A human biomonitoring survey was carried out to determine the concentrations of arsenic (As), mercury (Hg), thallium (Tl), antimony (Sb), cadmium (Cd), nickel (Ni), chromium (Cr), cobalt (Co), vanadium (V), and manganese (Mn). The associations between socio-demographics, lifestyle, diet, environmental exposure, and metal concentrations were evaluated using multiple log-linear regression models, adjusted for urinary creatinine. A total of 2034 urine and blood samples were collected. Adjusted geometric averages were higher in women (except for blood Hg) and younger subjects (except for Tl and Cd). Smoking was associated with Cd, As, and V. Some dietary habits (rice, fish, and wine consumption) were associated with As, Hg, Co, and Ni. Amalgam dental fillings and contact lenses were associated with Hg levels, piercing with As, Co, and Ni. Among environmental determinants, urinary As levels were higher in subjects using the aqueduct water for drinking/cooking. The consumption of locally grown fruits and vegetables was associated with Hg, Tl, and Co. Exposure to geothermal plant emissions was associated only with Tl.

Exposure to low levels of hydrogen sulphide and its impact on chronic obstructive pulmonary disease and lung function in the geothermal area of Mt. Amiata in Italy: The cross-sectional InVETTA study.

BACKGROUND: The geothermal power plants for electricity production currently active in Italy are all located in Mt. Amiata area in the Tuscany region. A cross-sectional survey was conducted in the framework of the regional project "InVETTA-Biomonitoring Survey and Epidemiological Evaluations for the Protection of Health in the Amiata Territories", using objective measures of lung function to investigate the role of hydrogen sulphide (H2S) in affecting the respiratory health of the population living in this area. METHODS: 2018 adults aged 18-70 were enrolled during 2017-2019. Home and workplace addresses of participants were geocoded. Dispersion modelling was used to evaluate the spatial variability of exposure to H2S from the geothermal power plants' emissions. We estimated average long-term historical exposure to H2S and more recent exposure indicators. Chronic Obstructive Pulmonary Disease (COPD) was defined according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Multivariable logistic regressions were performed to investigate associations between outcome and exposure. RESULTS: Our findings did not showed any evidence of an association between increasing H2S exposure and lung function impairments. Some risk reductions were observed: a -32.8% (p = 0.003) for FEV1<80% and a -51.7% (p = 0.001) risk decrease for FVC<80% were associated with interquartile increase (13.8 µg/m3) of H2S levels. CONCLUSION: Our study provides no evidence that chronic exposure to low levels of H2S is associated with decrements in pulmonary function, suggesting that ambient H2S exposure may benefit lung function.

[A national overview of the topics covered by young people in epidemiology: a comparison before and after the Covid-19.] / Un quadro nazionale delle tematiche trattate dai giovani in epidemiologia: un confronto prima e dopo il Covid-19.

INTRODUCTION: Epidemiology is increasingly involved on a wide variety of topics and to engage different professionals and disciplines in an increasingly active way. A fundamental role is played by young researchers active in Italian epidemiology who create opportunities for meeting and discussion, in the name of multidisciplinarity and integration of different skills. OBJECTIVE: The aim of this paper is to provide a detailed description of the topics most frequently studied in epidemiology by young people and to highlight any changes in these topics in the pre- and post-Covid-19 workplaces. METHODS: All abstracts submitted in the years 2019 and 2022 by young participants in the Maccacaro Prize, an annual award aimed at Italian association of epidemiology (Aie) conference addressed to people under 35 years of age, were considered. In addition to the comparison of the topics, a comparison of the related work structures and their geographical location was carried out by grouping the research centres into three Italian geographical regions: north, centre and south/islands. RESULTS: Between 2019 and 2022, the number of abstracts participating in the Maccacaro Prize increased. The interest in topics related to infectious diseases, vaccines, and pharmaco-epidemiology has sharply increased, while in environmental and maternal and child epidemiology it has moderately increased. Social epidemiology, health promotion and prevention, as well as clinical and evaluative epidemiology, have experienced a decrease in interest. Finally, after analysing the geographical distribution of reference centres, it was discovered that certain regions, such as Piedmont, Lombardy, Veneto, Emilia-Romagna, Tuscany and Latium, have a strong and consistent presence of young people in the field of epidemiology. Conversely, there is a small number of young professionals working in this field in other Italian regions, especially in Southern regions. CONCLUSIONS: The pandemic has changed our personal and working habits, but it has also played a fundamental role in making epidemiology known. The increase in young people joining an association such as the Aie is a clear sign of the growing interest in this discipline.

Presepsin for the Diagnosis of Neonatal Early-Onset Sepsis: A Systematic Review and Meta-analysis.

Importance: Neonatal early-onset sepsis (EOS) is a severe disease, particularly in preterm infants. Timely diagnosis can be challenging owing to unspecific presentation and questionable performance of the common markers of infection. Presepsin was recently proven to be a promising biomarker for the diagnosis of EOS. Objective: To assess presepsin accuracy for the diagnosis of EOS. Data Sources: PubMed Medline, EMBASE, Web of Science, and Google Scholar. No publication date restrictions were applied. The literature search was limited to the English language. Articles were checked for duplication. Study Selection: Inclusion criteria were studies that (1) included term or preterm newborns (defined as newborns with gestational age ≥37 weeks or <37 weeks, respectively); (2) included a diagnosis of EOS, defined as culture-proven sepsis for primary analysis and as either clinical or culture-proven sepsis for secondary analysis; and (3) assessed presepsin values during the initial workup for suspected EOS. Exclusion criteria were studies that (1) did not include EOS cases; (2) lacked data on presepsin sensitivity and/or specificity; and (3) were case reports, commentaries, or reviews. Two independent reviewers performed the study selection. Data Extraction and Synthesis: Two independent reviewers performed data extraction and quality assessment. Quality assessment was performed using the Quality Assessment for Studies of Diagnostic Accuracy 2 tool, and data were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were pooled using a random-effects model. Main Outcomes and Measures: The outcomes of interest for both the primary and secondary analyses were presepsin sensitivity, specificity, and diagnostic odds ratio for the diagnosis of EOS. Results: A total of 12 studies of 245 (4.9%) met inclusion criteria for the primary analysis. Twenty-three studies of 245 (9.4%) met the inclusion criteria for the secondary analysis. In the primary analysis, among 12 studies and 828 newborns of any gestational age, pooled sensitivity and specificity were 0.93 (95% CI, 0.86-0.95) and 0.91 (95% CI, 0.85-0.95), respectively; pooled diagnostic odds ratio was 131.69 (95% CI, 54.93-310.94). Subgroup analysis showed that presepsin specificity was associated with the inclusion of only EOS or all neonatal sepsis. Presepsin accuracy was not associated with gestational age, measurement with chemiluminescence enzyme immunoassay or enzyme-linked immunosorbent assay testing, country where the study was performed, or risk of bias judgment. In the secondary analysis, among 23 studies and 1866 newborns, accuracy was significantly associated with only test type. Conclusions and Relevance: Results of this systematic review and meta-analysis suggest that presepsin was an accurate biomarker of EOS. Clinical trials are warranted to assess its usefulness and safety to reduce early antibiotic exposure, particularly in preterm newborns.

Efficacy of Plant Sterol-Enriched Food for Primary Prevention and Treatment of Hypercholesterolemia: A Systematic Literature Review.

Plant sterols/phytosterols (PSs) are molecules with a similar structure to cholesterol that have a recognized effect on elevated LDL concentrations (LDL-c). PSs are used as a natural therapy against elevated LDL-c in combination with a healthy diet and exercise. A systematic review was performed to evaluate the efficacy of PS-enriched foods in the treatment of hypercholesterolemia. Randomized controlled clinical studies reporting the use of PS-enriched foods to reduce LDL-c among adult individuals were retrieved and assessed for risk of bias. Meta-analyses were performed to assess changes in LDL-c by treatment, food matrix, LDL-c range, sterols dosage and risk of bias (RoB). In the 13 studies analyzed, LDL-c in PS-treated participants decreased by an average of 12.14 (8.98; 15.29) mg/dL. PS administration was statistically more effective in patients with LDL-c ≥ 140 mg/dL and for PS dosages > 2 g/day. It can be concluded that PSs can be used as an important primary prevention measure for hypercholesterolemia and as tertiary prevention for cardiovascular events in patients who already have mild to moderate LDL-c. However, in severe hypercholesterolemia and in cases of familial hypercholesterolemia, it is necessary to combine dietary treatment with the use of statins.

Adherence and Persistence to Biological Drugs for Psoriasis: Systematic Review with Meta-Analysis.

Despite the large number of biologics currently available for moderate-to-severe psoriasis, poor adherence and persistence to therapy represent the main issues for both the clinical and economic management of psoriasis. However, the data about adherence and persistence to biologics in psoriasis patients are conflicting. Our aim was to produce summary estimates of adherence and persistence to biologics in adult patients with psoriasis. We performed a systematic review and meta-analysis of observational studies, searching two databases (PubMed and Embase). Sixty-two records met the inclusion criteria, and a meta-analysis was conducted on fifty-five studies. Overall, the proportion of adherent and persistent patients to biological therapy was 0.61 (95% confidence interval: 0.48-0.73) and 0.63 (0.57-0.68), respectively. The highest proportions were found for ustekinumab, while the lowest ones were found for etanercept. The proportions of adherence and persistence to biological drugs in psoriasis patients are sub-optimal. Notably, both proportions largely differ between drugs, suggesting that a more rational use of biologics might ensure better management of psoriasis.
