A 2-year point-prevalence surveillance of healthcare-associated infections and antimicrobial use in Ferrara University Hospital, Italy.

BACKGROUND: Healthcare-Associated Infections (HAIs) represent one of the leading issues to patient safety as well as a significant economic burden. Similarly, Antimicrobial Use (AMU) and Resistance (AMR) represent a growing threat to global public health and the sustainability of healthcare services. METHODS: A Point Prevalence Survey (PPS) following the 2016 ECDC protocol for HAI prevalence and AMU was conducted at Ferrara University Hospital (FUH). Data were collected by a team of trained independent surveyors in 2016 and 2018. Risk factors independently associated with HAI were assessed by a multivariate logistic regression model. RESULTS: Of the 1102 patients surveyed, 115 (10.4%) had an active HAI and 487 (44.2%) were on at least 1 systemic antimicrobial agent. Factors independently associated with increased HAI risk were a "Rapidly Fatal" McCabe score (expected fatal outcome within 1 year), presence of medical devices (PVC, CVC, indwelling urinary catheter or mechanically assisted ventilation) and a length of hospital stay of at least 1 week. The most frequent types of HAI were pneumonia, bloodstream infections, and urinary tract infections. Antimicrobial resistance to third-generation cephalosporins was observed in about 60% of Enterobacteriaceae. CONCLUSIONS: The survey reports a high prevalence of HAI and AMU in FUH. Repeated PPSs are useful to control HAIs and AMU in large acute-care hospitals, highlighting the main problematic factors and allowing planning for improvement actions.

Identifying people at risk for influenza with low vaccine uptake based on deprivation status: a systematic review.

BACKGROUND: Influenza vaccination is an important public health intervention for controlling disease burden, but coverage rates are still low also in risk groups. In order to identify non-vaccinating subgroups, deprivation and socio-economic indices, i.e. measures used to synthetically describe people's socio-economic status while taking into account several dimensions, may be used. We aimed to synthetize evidence from studies investigating association between deprivation/socio-economic indices and influenza vaccination coverage in population at risk-persons ≥65 years of age, individuals with comorbidities, pregnant women and health-care workers. METHODS: We searched PubMed, ISI WoS, CINAHL and Scopus to identify observational studies published up to October 10th 2017 in English or Italian. Studies reporting quantitative estimates of the association between deprivation/socio-economic indices and influenza vaccination coverage in populations at risk were included. RESULTS: A total of 1474 articles were identified and 12 were eventually included in the final review. Studies were mostly cross-sectional, performed in European countries, from 2004 to 2017. Seven studies focussed on deprivation and five on socio-economic indices. Studies on deprivation indices and vaccination coverage showed that people from the most deprived areas had lower coverage. Regarding socio-economic condition, results were contrasting, even though it may also be concluded that people from lower groups have lower vaccination coverage. CONCLUSIONS: Our work supports the possibility to identify people likely to have lower influenza vaccination coverage based on deprivation/socio-economic indices. Efforts should be performed in order to further strengthen robustness, transferability and suitability of these indices in addressing public health problems.

Diagnostic anticipation to reduce emergency department length of stay: a retrospective cohort study in Ferrara University hospital, Italy.

BACKGROUND: Emergency Department (ED) crowding reduces staff satisfaction and healthcare quality and safety, which in turn increase costs. Despite a number of proposed solutions, ED length of stay (LOS) - a main cause of overcrowding - remains a major issue worldwide. This retrospective cohort study was aimed at evaluating the effectiveness on ED LOS of a procedure called "Diagnostic Anticipation" (DA), which consisted in anticipating the ordering of blood tests by nurses, at triage, following a diagnostic algorithm approved by physicians. METHODS: In the second half of 2019, the ED of the University Hospital of Ferrara, Italy, adopted the DA protocol on alternate weeks for all patients with chest pain, abdominal pain, and non-traumatic bleeding. A retrospective cohort study on DA impact was conducted. Using ED electronic data, LOS independent predictors (age, sex, NEDOCS and Priority Color Code, imaging tests, specialistic consultations, hospital admission) were evaluated through multiple regression. RESULTS: During the weeks when DA was adopted, as compared to control weeks, the mean LOS was shorter by 18.2 min for chest pain, but longer by 15.7 min for abdominal pain, and 33.3 for non-traumatic bleeding. At multivariate analysis, adjusting for age, gender, triage priority, specialist consultations, imaging test, hospitalization and ED crowding, the difference in visit time was significant for chest pain only (p < 0.001). CONCLUSIONS: The impact of DA varied by patients' condition, being significant for chest pain only. Further research is needed before the implementation, estimating the potential proportion of inappropriate blood tests and ED crowding status.

Temporal trends in herpes zoster-related hospitalizations in Italy, 2001-2013: differences between regions that have or have not implemented varicella vaccination.

BACKGROUND: Herpes zoster (HZ) has a relevant impact on the population in terms of incidence and complications. AIMS: The aim of this study was to estimate the HZ-related hospitalization rates in Italy in the period 2001-2013, and to evaluate the trend of hospitalizations in the course of time pointing out any differences between regions that have or have not introduced universal childhood varicella immunization (UVI). METHODS: A retrospective analysis was conducted on hospital discharge records contained in the national database of the Ministry of Health for the period January 2001-December 2013. The comparison of hospitalization rates of "pilot" versus "not pilot" regions was performed taking into account as "pilot" regions the three that first introduced UVI (Sicily, Veneto, and Apulia). The average annual percentage change in hospitalization rates was used to highlight any significant change in time trends. RESULTS: In the period 2001-2013, 93,808 HZ-related hospitalizations were registered altogether. Complicated HZ was diagnosed in 53.2% of cases; a relevant part (32.5%) of hospitalizations involved subjects with at least one co-morbidity. In the three Italian "pilot" regions, a greater decrease of HZ-related hospitalization rates occurred in comparison to other regions. DISCUSSION: A good understanding of the epidemiology of HZ disease is required to assess the overall impact of the varicella immunization programs and to establish the most appropriate health strategies against HZ. CONCLUSIONS: The data obtained confirm the epidemiological impact of HZ and its complications and the need of a preventive approach.

Pedestrian Inattention Blindness While Playing Pokémon Go as an Emerging Health-Risk Behavior: A Case Report.

BACKGROUND: Cases of trauma resulting from the use of mobile phones while driving motor vehicles have become quite common in recent years. Road injuries incurred by people playing video games on mobile phones (or other media devices) while walking have also become a cause for concern. Pokémon Go has been the world's most popular game since it was launched in July 2016, with more than 15 million players trying to catch all Pokémon available in the game; however, the case detailed here is the first reported accident in the medical literature caused by a pedestrian distracted by the game while crossing a street. OBJECTIVE: We aim to provide additional information on the innovative nature of distractions that generate risks in road-users, and to explore the underreporting of pedestrian-motor vehicle collisions due to mobile device usage. METHODS: We included in this case report a 25-year-old male who suddenly crossed a road while playing Pokémon Go and was hit by a van, reporting several injuries and being assisted by the Emergency Medical Service of our hospital (Padova, Italy). The patient's history, the circumstances in which the collision happened, imaging data, and clinical course information were recorded per our hospital's privacy policy. RESULTS: The patient hit by the van was playing Pokémon Go on his mobile phone while crossing a street, despite red traffic lights, which he did not notice due to of the distraction induced by the game. CONCLUSIONS: Mobile videogames that imply movement (ie, walking, running, cycling) to play are an effective way to improve physical activity practice, especially in adolescents and young adults. Nevertheless, cases like the one presented here point out that these games could pose a significant risk to users who play while walking, cycling, or driving in unsafe areas such as city streets, because players become distracted and may ignore surrounding hazards. Comprehensive, multilevel interventions are needed to reduce accidents caused by distraction, and to stress findings on the positive and negative effects of video games, which are becoming a source of public health concern. Health care providers should be aware of their chief role in these possible prevention strategies, based on their direct interactions with road incident victims.

[Incidence of biological accidents at work and immune status for vaccine-preventable diseases among resident physicians in specialist training at Ferrara University Hospital]. / Studio di incidenza sugli infortuni biologici nei medici in formazione specialistica dell'Azienda Ospedaliero - Universitaria di Ferrara e stato immunitario nei confronti delle principali infezioni prevenibili.

The hospital as a work environment is particularly characterized by various risks for healthcare workers (HCWs). The main risk is represented by biological accidents, associated with the parenteral transmission of pathogens. Biological injuries can occur during the care service and the manipulation of biological fluids. Hepatitis B (and hepatitis D), hepatitis C and HIV are the most common infections transmitted by biological injuries. Physicians should acquire awareness of the risks associated with their professional activity during their training as medical residents (MRs). Some infectious diseases are preventable by vaccination and the "National Immunization Plan 2017-2019" (PNPV) recommends HCWs vaccination against hepatitis B, influenza, measles -mumps -rubella, chicken pox, and pertussis. Besides, not only HCWs' vaccination can prevent the disease in healthcare professionals, but it also may reduce the transmission to patients. Therefore, active immunization of HCWs by recommended vaccinations plays an important role to prevent disease cases, complications and death in patients. An increased awareness of risk behaviors is the first important point to address in order to reduce biological accidents and infectious diseases transmission, so as to reduce their frequency. Besides, HCWs' vaccination is useful to reinforce protection and to prevent the transmission of some infectious diseases in case of exposure. The aim of this five-year incidence study is to investigate the MRs' biological accidents characteristics and to analyze the MRs' immune status at the University of Ferrara in the period 2011-2015. Data on MRs' biological accidents and immune status at Azienda Ospedaliero-Universitaria of Ferrara in 2011-2015 were analyzed by Microsoft Excel 2007 Software. In this study, the percentage of MRs' biological injuries compared to the total number of MRs showed an annual variability, with a peak in 2011 (11.9%). During the analyzed period, there were 190 biological injuries among the MRs: 81% were percutaneous injuries and blood was the biological fluid involved in 86.3% of cases. The most frequent lesion was puncture (62.6%), occurred in 41.1% of cases by suture needles; 46.3% of accidents occurred in the operating block. These data can be explained by the more invasive and at risk activities carried out in these Operative Units. The high injuries percentage in MRs may be related to less work experience and inadequate training or informations about personal protective equipment use. Among MRs, 93.7%, 93.3% and 96.6% were immune to measles, chicken pox and hepatitis B, respectively; only in the case of rubella, 11.9% of MRs was not immune. This research showed, accordingly to published data, high adhesion to hepatitis B vaccination. However, the healthcare workers' vaccine coverage is still sub-optimal; active immunization by recommended vaccines should be implemented for both parenteral and airborne diseases. As a matter of fact, the recent measles outbreak has involved healthcare workers (4689 cases of measles, 305 in HCWs). Finally, the General Directorates of Health-care settings should improve healthcare personnel adhesion to vaccinations, such as influenza, by promotion activities in the workplace. A proposal in order to achieve coverage objectives could be making vaccinations mandatory, as well as already implemented in other countries.

Varicella-zoster virus: pathogenesis, incidence patterns and vaccination programs.

Varicella or chickenpox is a common and highly contagious exanthematic disease caused by the varicella-zoster virus (VZV) that during primary infection has the ability to establish latency. VZV reactivation, even decades after primary infection, causes herpes zoster. In healthy immunocompetent subjects, children in particular, varicella results in mild to moderate illness and for this reason, regardless its high morbidity, it is not considered a public health priority. Varicella still represents the most widespread vaccine preventable childhood infectious disease in industrialized countries; due to its relevant burden on healthcare resources several countries has introduced varicella vaccination into the recommended routine childhood national immunization schedule. Nowadays, live attenuated monovalent and combined MMRV vaccines are licensed worldwide. The use of several millions of doses has demonstrated the excellent safety and efficacy level of varicella vaccines as well as of combined MMRV vaccines. Universal vaccination adopted in many countries with a two-dose strategy has allowed to significantly reducing morbidity and mortality of this infectious disease. Anyway, an ample international debate is ongoing on the time range to be used between the two doses, and on the safety issues related to the use as first-dose of MMRV vaccine. Taking into account the availability of a zoster vaccine in subjects older than 50 years of age, it will be relevant to clarify if an impact on exogenous boosters and on the epidemiology of herpes zoster can occur after the adoption of extensive varicella immunization.

[Evaluation of chlorine dioxide concentrations needed to effectively control contamination by Legionella spp in hospital hot water distribution systems]. / La determinazione della concentrazione efficace di biossido di cloro (ClO2) per il controllo della contaminazione da Legionella spp nei circuiti dell'acqua calda sanitaria.

This aim of the study was to identify effective levels of ClO2 for control of Legionella spp. contamination in the hot water (45-55 °C.) distribution system of a 579-bed hospital in Ravenna (Italy). Overall, 663 hot water samples were collected from the hospital's sinks and shower taps and were analyzed. Trend line analysis, which describes the trend in the number of positive samples collected according to disinfectant concentration, shows that the lowest number of positive samples was achieved with concentrations of ClO2 between 0.22 and 0, 32 mg /l.

[A survey on injuries among nurses and nursing students: a descriptive epidemiologic analysis between 2002 and 2012 at a University Hospital]. / Indagine sugli infortune tra il personale infermieristico e gli studenti del corso di laurea in infermieristica: analisi epidemiologica descrittiva nel period 2002-2012 in un'Azienda Ospedaliero-Universitaria.

BACKGROUND: Biological risk is the main occupational hazard in hospitals (40-50% of the total). More than 130,000 injuries occur every year in Italy and nurses are the most affected occupational category. OBJECTIVES: This study evaluated the incidence of injuries related to biological risk in nurses and nursing students in the University Hospital of Ferrara, how they occur, the knowledge on the topic and on behaviour during the department's activity. METHODS: A retrospective study involving a sample of 8 departments (selected for the occurrence of more than 30 biological injuries between 1st January 2002 and 31 December 2012) recorded injuries related to biological risk; subsequently a cross-sectional survey was carried out through a questionnaire administered to nurses and nursing students. RESULTS: 909 biological accidents were reported (81.18% in nurses and 18.82% in students). Blood was the main biological material involved (83.72% of cases), mostly by percutaneous exposure (84.16%). According to the questionnaire, 53% of subjects reported having had at least one injury during their career, and 5.72% did not report it; 46% reported doing risky procedures (re-capping needles) and 95.45% that they had been informed about the correct use of PPE. CONCLUSIONS: The lower percentage of injuries in students could be linked to good university training and to less risky procedures being performed. Re-capping needles remains one of the most dangerous manoeuvers practised. Ongoing training on the correct use of PPE is essential to train prepared and aware health professionals.

Knowledge about tuberculosis among undergraduate health care students in 15 Italian universities: a cross-sectional study.

BACKGROUND: The Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health conducted a multicentre survey aiming to evaluate undergraduate health care students' knowledge of tuberculosis and tuberculosis control measures in Italy. METHODS: In October 2012-June 2013, a sample of medical and nursing students from 15 Italian universities were enrolled on a voluntary basis and asked to complete an anonymous questionnaire investigating both general knowledge of tuberculosis (aetiology, clinical presentation, outcome, screening methods) and personal experiences and practices related to tuberculosis prevention. Data were analysed through multivariable regression using Stata software. RESULTS: The sample consisted of 2,220 students in nursing (72.6%) and medicine (27.4%) courses. Our findings clearly showed that medical students had a better knowledge of tuberculosis than did nursing students.Although the vast majority of the sample (up to 95%) answered questions about tuberculosis aetiology correctly, only 60% of the students gave the correct responses regarding clinical aspects and vaccine details. Overall, 66.9% of the students had been screened for tuberculosis, but less than 20% of those with a negative result on the tuberculin skin test were vaccinated. Multivariable regression analysis showed that age and type of study programme (nursing vs. medical course) were determinants of answering the questions correctly. CONCLUSIONS: Although our data showed sufficient knowledge on tuberculosis, this survey underlines the considerable need for improvement in knowledge about the disease, especially among nursing students. In light of the scientific recommendations concerning tuberculosis knowledge among students, progress of current health care curricula aimed to develop students' skills in this field is needed.

Active surveillance of adverse events after immunization (AEFI) from the Local Health Unitof Ferrara, Italy.

Introduction: Vaccine vigilance implies the collection, evaluation, analysis and communication of adverse events following immunization (AEFI) and is a useful tool for vaccine monitoring allowing, even after approval and marketing, to check its safety/tolerability. The multiregional project "Active surveillance of adverse vaccine reactions", joined by the AUSL of Ferrara, is aimed at making parents of children, who have undergone at least one vaccination provided by the regional vaccination calendar in the first 24 months of life, aware of the reporting of any AEFI via mobile phone-SMS. Methods: An analysis of the project data, collected in the period March 2018 - May 2019, was carried out, to evaluate the effectiveness of the reporting tool and the type and frequency of AEFI. Anonymized data were analyzed by number, gender, distribution by age, type of vaccine, adverse event, severity and outcome. Results: A total of 1,494 consents and 983 SMS messages were obtained from parents. The vaccine doses carried out were 1,984 (28.3% hexavalent, 28% PCV13, 17% anti-rotavirus, 14.3% Men-B). Almost all (99.5%) AEFI were classified as "not serious". Based on the Organ System Class (SOC), most reports are related to "General Disorders and Administration Site Conditions" (52.3%), followed by "Psychiatric Disorders" (26.5%) and "Metabolic and nutrition disorders" (12.5%). Conclusions: The reported AEFI are in line with the ones reported in the literature. Reporting via SMS is a valid vaccine surveillance tool contributing to the qualitative and quantitative improvement of the information transmitted.

COVID-19: opinions and behavior of Italian general population during the first epidemic phase.

BACKGROUND AND AIM: On January 9, 2020, the World Health Organization (WHO) declared that Chinese health authorities had identified a new coronavirus strain never before isolated in humans, the 2019-nCoV later redefined SARS-CoV-2, that still today represent a public health problem. The present survey started on 10 February 2020 with the aim of a) assessing the risk perception in healthcare workers and young students, following the evolution of attitudes, perception and knowledge over time, b) provide useful information to the general population during survey. RESULTS: A study sample consisting of 4116 Italian individuals of both sexes was enrolled. High levels of risk perception, low perception of self-efficacy and low levels of knowledge scores (24.55 ± 5.76 SD) were obtained indicating the need for continuous population monitoring as well as further communication strategies carried out at institution levels. CONCLUSION: The results of the present study could help public health authorities in carrying out informative campaigns for general population and could be an important tool in evaluating public knowledge and misperceptions during the management of the COVID-19.

Trends in influenza coverage rates in five consecutive immunisation seasons in the Local Health Unit of Ferrara (North Italy).

Seasonal influenza epidemics yearly affects 5-15% of the world's population, resulting in 3-5 million serious cases and up to 650,000 deaths. Elderly, pregnant women and individuals with underlying conditions are at increased risk of complications. According to the Italian National Immunisation Prevention Plan 2017-2019, these categories benefit from free vaccination but coverage rate in Italy are below desirable levels. The study considered the coverage rate in five consecutive influenza seasons (2010/2011-2014/2015) in Local Health Unit (LHU) of Ferrara (Italy). The amount of delivered vaccinations was not constant, with a decreasing trend. Coverage rose with increasing age, but the 75% target of over-65 years old individuals immunised was never achieved. In addition to age, coverage rates varied also according to District (the area of residence within the LHU). The District with the lowest vaccination coverage was the Western District. Higher levels of immunisation were observed in South-Eastern District in the pediatric age and in North-Central District in adult age group with a statistically significant difference. In the considered timespan, the percentage of immunisations delivered by the General Practitioners (GPs) increased. The trend in the LHU of Ferrara was similar to regional and national data, conditioned in the 2014/2015 season by the spreading of worrying news, although unfounded, on the safety of the vaccine. The GPs were essential in ensuring vaccine uptake, growing the percentage of delivered doses and achieving as much as possible effective elderly immunisation.

Human Papilloma Virus Vaccination: Focus on the Italian Situation.

Human papilloma virus (HPV) is a viral agent whose transmission occurs mainly by sexual means. It causes different pathological conditions in both males and females, ranging from benign pathologies up to cancers. The introduction of vaccination has certainly had a major impact in terms of reducing the incidence of both HPV infections and diseases but in the European Union and the European Economic Area (EU/EEA) there are still about more than 13,000 deaths due to cervical cancer each year. To date in Europe and in Italy there are three vaccines available (bi-, tetra-, and nonvalent vaccines). The vaccination campaign started irregularly in Europe and Italy in 2007, with pre-adolescent girls as the primary target. Later, other cohorts were introduced such as 12-year-old boys, additional cohorts of >25-year-old women, women who already underwent cervical surgery and other subjects entitled to free vaccination. The COVID-19 pandemic has strongly impacted on public health services, particularly on vaccinations that, especially during the first pandemic phase, have been often delayed and/or canceled. The most affected vaccinations by the pandemic have been the non-mandatory ones, particularly those addressing the adolescent and adult population, such as immunization against papillomavirus. To date the achievement of the coverage target set by the Italian National Immunization Plan (NIP) has not yet been achieved. The aim of this work is to summarize the current situation in Italy and to discuss the strategies that have been implemented to increase overall vaccination coverage rates.

The Epidemiological Characteristics of the COVID-19 Pandemic in Europe: Focus on Italy.

Starting from December 2019, SARS-CoV-2 has forcefully entered our lives and profoundly changed all the habits of the world population. The COVID-19 pandemic has violently impacted the European continent, first involving only some European countries, Italy in particular, and then spreading to all member states, albeit in different ways and times. The ways SARS-CoV-2 spreads are still partly unknown; to quantify and adequately respond to the pandemic, various parameters and reporting systems have been introduced at national and European levels to promptly recognize the most alarming epidemiological situations and therefore limit the impact of the virus on the health of the population. The relevant key points to implement adequate measures to face the epidemic include identifying the population groups most involved in terms of morbidity and mortality, identifying the events mostly related to the spreading of the virus and recognizing the various viral mutations. The main objective of this work is to summarize the epidemiological situation of the COVID-19 pandemic in Europe and Italy almost a year after the first reported case in our continent. The secondary objectives include the definition of the epidemiological parameters used to monitor the epidemic, the explanation of superspreading events and the description of how the epidemic has impacted on health and social structures, with a particular focus on Italy.

Value of Immunizations during the COVID-19 Emergency.

Recent estimates by World Health Organization (WHO, Geneva, Switzerland) and United Nations International Children's Emergency Fund (UNICEF) show a significant decline in vaccinal coverage rates in both pediatric and adult populations. The interruption of vaccination services is reported in at least 68 countries, with the involvement of about 80 million children worldwide. The situation is alarming if we consider that already in the period preceding the pandemic, immunization programs slowed down in various areas of the world. For these reasons, there is the risk of overloading health systems, already under pressure from the pandemic emergency, by employing human and economic resources for the management of epidemic outbreaks from vaccine-preventable diseases. The restoration and integration of vaccination services, the immunization of susceptible individuals as well as the adoption of adequate monitoring and surveillance measures are the main activities adopted by different countries to address the current global health emergency.

Coronavirus: Update Related to the Current Outbreak of COVID-19.

In December 2019, some cases of viral pneumonia were epidemiologically related to a new coronavirus in the province of Hubei, China. Subsequently, there has been an increase in infections attributable to this virus throughout China and worldwide. The World Health Organization (WHO) has officially named the infection coronavirus disease 2019 (COVID-19), and the virus has been classified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This appears to be a virus from Rhinolophus bats, but the intermediate host has not yet been identified. The mechanism of infection of SARS-CoV-2 is not yet known; it appears to have affinity for cells located in the lower airways, where it replicates. The interhuman transmission of coronaviruses mainly occurs through saliva droplets and direct and indirect contact via surfaces. As of March 10, 2020, the number of cases worldwide was 113,702. Along with severe acute respiratory syndrome (SARS) and Middle Eastern respiratory syndrome (MERS), COVID-19 appears to cause a severe clinical picture in humans, ranging from mild malaise to death by sepsis/acute respiratory distress syndrome. The prognosis is worse in elderly patients with comorbidities. To date, there is no specific therapy for COVID-19. Prevention of SARS-CoV-2 infection implies strategies that limit the spread of the virus. WHO and other international and national bodies have developed continuously updated strategic objectives and provisions to contain the spread of the virus and infection.

Influenza coverage rates in subjects with chronic heart diseases: results obtained in four consecutive immunisation seasons in the Local Health Unit of Ferrara (North Italy)".

BACKGROUND: Seasonal influenza epidemics yearly affects 5-15% of the world's population, resulting in 3-5 million serious cases and up to 650,000 deaths. According to the 2017-2019 Italian National Immunisation Plan, free immunisation is offered to the categories at increased risk of experience the complications of the infection (over 65 years old subjects, pregnant women and individuals with underlying conditions, including chronic heart diseases). Rising evidence suggests that influenza can trigger adverse cardiovascular events therefore the vaccination is recommended for secondary prevention of cardiovascular diseases. Despite this, the influenza coverage rate in subjects with chronic heart disease is underestimated. METHODS: The study investigated the coverage rate in four consecutive influenza seasons (from 2011/2012 to 2014/2015) in subjects that benefit from exemption from paying healthcare costs for chronic heart disease living in Local Health Unit (LHU) of Ferrara (Italy), comparing the databases of exemptions and immunisations. RESULTS: The levels of influenza vaccine uptake were unstable, reaching the 50.3% in 2011/2012 immunisation season and falling to 42.2% in the following year. Coverage rates increased with increasing age, without achieving the 75% target, neither in over 65 years old subjects. The logistic regression analysis showed that influenza coverage rates were statistically significant different (p < 0.0001, 0.003 only for category of disease in 2011/2012 immunisation season) according to age, district of residence, category of chronic heart disease and length of exemption, but not influenced by gender. CONCLUSIONS: The recommendation of influenza immunisation was weakly followed in individuals with chronic heart diseases. A collaboration between cardiologists, GPs, scientific societies and patient associations could successfully support influenza vaccine uptake.

Viral Respiratory Infections in Hematological Patients.

Viral infections of the respiratory system represent one of the most important complications in hematological patients in terms of both the severity of the clinical picture and its related impact on the duration of hospitalization, and of mortality. The most implicated viruses are those that commonly cause community-based respiratory diseases: respiratory syncytial virus, Influenza virus and rhinovirus. However, in some cases the clinical picture may be triggered by first infection with or reactivation of pathogens normally not responsible for clinically relevant diseases in immunocompetent subjects. This issue is currently being taken into greater consideration within the scientific community. However, the strong heterogeneity in the epidemiology and clinical expression of these infections and the lack of adequate therapeutic options imply that there is currently no uniform consensus on the best management of these patients. The main purpose of this review is to highlight which viruses are currently most implicated in the onset of these infections, what is their incidence in so heterogeneous and fragile patients and the factors that lead to disease's onset and evolution. Possible or available clinical management options, diagnostic and therapeutic tools, and preventive and prophylaxis measures are also discussed.

Impact of Pertussis on the Italian population: Analysis of hospital discharge records in the period 2001-2014.

OBJECTIVES: The study aimed to analyze and update the impact of pertussis on the Italian population by evaluating pertussis-related hospital admissions in the period 2001-2014. DESIGN OR METHODS: Hospital Discharge Records (HDR) were provided by the National Archive of HDR data of the Ministry of Health. Only hospitalizations included in the primary diagnosis were evaluated. Significant trends over the considered years were assessed as average annual percent changes (AAPC) applying the Joinpoint model. RESULTS: A total of 7,102 hospital admissions for pertussis (main diagnosis) were registered; the trend of hospitalizations progressively decreased from >1/100,000 inhabitants in the years 2001-2004 to 0.64/100,000 inhabitants in 2014. A great part of hospitalizations (63.6%) involved subjects <1 year of life; almost 20% of cases were registered in the age class 5-14 years. The Joinpoint analysis showed a statistically significant variation in some age classes. CONCLUSIONS: Even if this study shows a decreasing trend in the number of pertussis-related hospitalizations, the impact of the disease in Italy in terms of hospital admissions continues to be relevant, especially in the <1 year age class. Pertussis therefore continues to be, in Italy as well as in other European countries, an important public health issue.
