Dear Editor, We would like to reply to "Safety of mRNA BNT162b2 COVID-19 (Pfizer-BioNtech) vaccine in children aged 5-11years: Correspondence" regarding our article entitled "Safety of mRNA BNT162b2 COVID-19 (Pfizer-BioNTech) vaccine in children aged 5-11years: Results from an active pharmacovigilance study in central Italy."

Infections and Colon Surgery: Preliminary Results from a Surveillance Program in an Italian Hospital.

Surgical site infections (SSIs) represent a valid indicator of the healthcare quality. This study described the preliminary results of one-year active surveillance program on colon surgeries in a hospital in Molise region, central Italy. Patients who had undergone colon surgery according to National Healthcare Safety Network were included. Data on intervention, perioperative antibiotic prophylaxis, and SSIs occurrence were collected. Chi-square and Fisher's Exact test were used to evaluate any association between risk factors and SSIs. Sixty-eight patients (mean age 70.6 years) were included, and 44 (64.7%) were males. The most frequent interventions were right (n = 17, 25.0%) and left (n = 15, 22.0%) hemicolectomy. Surgical interventions were largely elective (n = 43, 63.2%) and with laparotomy (n = 56, 82.4%). During hospital stay, 10 (14.7%) SSIs were detected, including five superficial, three deep and two organ/space infections. Three (4.4%) additional SSIs were detected at post-discharge follow-up, for 13 (19.1%; CI95%: 9.7%-28.5%) total cases detected. Metronidazole plus Ceftriaxone (third generation cephalosporin) was the antibiotics combination mostly used (n = 36, 52.9%) for the perioperative antibiotic prophylaxis within 60 minutes of incision. The study underlines the need of improvements of the practices currently adopted, since SSIs could be significantly reduced through a multimodal strategy generating bundles. As third generation cephalosporins may facilitate resistant strains emergence, for perioperative prophylaxis in clean-contaminated interventions with entry into gastrointestinal tract, Cefazolin plus Metronidazole or only second generation cephalosporin are recommended. Due to the large variability of post-intervention antibiotic therapy, antimicrobial stewardship approach is strictly necessary.

Healthcare infections and antimicrobial consumption in pre-COVID-19 era: a point prevalence survey in three hospitals in a region of Central Italy.

Introduction: Healthcare-associated infections (HAIs) are a major global public health concern, increasing the transmission of drug-resistant infections. This point prevalence survey investigated HAIs occurrence and antimicrobial consumption (AMC) in pre-COVID-19 era in the public hospitals of a region of Central Italy. Methods: Data were collected using the protocol standardised by the European Centre for Disease Prevention and Control. Results: Three-hundred and sixty-four patients were included (59.3% male) in the study. Overall, HAIs prevalence was 6.6% (95%CI 4.4-9.5), ranging from 5.2% to 7.1% within the surveyed hospitals, with at least one infection in 24 patients (ten each in medical and surgical specialties wards, and four in intensive care). Risk factors for HAIs were advanced age, having undergone surgery and wearing invasive devices. At time of the survey, 44.7% (95%CI 39.7-49.9) of patients was under treatment with at least one antibiotic, and AMC varied between 43% and 48% within hospitals. In all hospitals, a prevalence higher than 10% was found for the prescription reasons other than prophylaxis or therapy. Conclusions: The results revealed a HAIs prevalence lower than that estimated compared to the most recent national data, in contrast to higher antimicrobial usage. These findings highlight the need to reinforce hygiene practices and develop bundles for HAIs, as a broad implementation of infection prevention and control practices extensively applied to both hub and spoke hospitals could significantly reduce their occurrence, as well as to implement antimicrobial stewardship for prescriptive appropriateness.

Safety of mRNA BNT162b2 COVID-19 (Pfizer-BioNtech) vaccine in children aged 5-11 years: Results from an active pharmacovigilance study in central Italy.

This survey investigated on adverse events after vaccination with mRNA BNT162b2 (Comirnaty, Pfizer-BioNTech) vaccine in children aged 5-11 years in central Italy through active surveillance reporting. During December 2021-January 2022, parents of children who undergone vaccination were interviewed using a structured questionnaire. 197 out of 208 contacted parents participated (94.7% response rate), of whom 166 (84.3%) had one child. Of the 229 children, the mean age was 8.9 years, 50.7% were female. 193 (84.3%) had at least one adverse event after the first dose (mean age 9.1 years; 54.4% female), and 146 (73.4%) of 199 after the second (mean age 8.9 years; 54.8% female), which was not administered to 30 children due to previous COVID-19 history. Local symptoms after the first and second dose occurred in 183 (94.8%) and 141 (96.6%) recipients (p = .435), respectively, while systemic reactions in 62 (32.1%) and 34 (23.3%) (p = .074). Mild events were reported by 81.7% and 69.8% children after the first and second dose, followed by moderate (3.9% and 10.6%) and severe (1.3% and 0.5%). After each dose, injection site reactions (79.5% and 68.8%) were the most frequent, followed by headache (13.1%) and lymphadenopathy (8.5%) after the first and second dose, respectively. The adverse events were reported to pediatricians only for 5.7% and 3.9% of children and treated for 17.6% and 15.8%. This is the first report about safety profile through active surveillance of mRNA BNT162b2 among children in Italy, revealing temporary and mild-to-moderate symptoms with no serious events after each vaccine dose.

Public health, personalized medicine, and COVID-19 in the pre-vaccination phase: a narrative review of the literature on unfavorable prognostic factors in Italian patients.

OBJECTIVES: to provide an outline of the factors mainly influencing severe disease and fatal outcome among Italian COVID-19 patients in the pre-vaccination phase, also describing the impact of the scenarios driven by variants, vaccines, and available therapies. DESIGN: a literature search was carried out for peer-reviewed articles searching for COVID-19 and prognosis, including severe disease and death. SETTING AND PARTICIPANTS: Italian patients with COVID-19. MAIN OUTCOME MEASURES: the association between risk factors and severe disease and death as the main outcomes was assessed through epidemiological measures, including relative risk, odds ratio, and hazard ratio. RESULTS: advanced age, obesity, overweight, non-0 blood group, and male gender were the factors more associated with severe disease. Fatal outcome mostly correlated with old age, non-0 blood group, and obesity, together with cardiovascular diseases, diabetes, hypertension, cancer, chronic kidney disease, and acute kidney injury. CONCLUSIONS: clinical and epidemiological characteristics of the Italian population, integrated with omics data, could be highly valuable to stratify risk of worse prognosis among patients, and to address targeted prevention and treatment interventions.

A Cross-Sectional Study of Untoward Reactions Following Homologous and Heterologous COVID-19 Booster Immunizations in Recipients Seventeen Years of Age and Older.

A booster dose after primary COVID-19 vaccination series was considered crucial after the emergence of the B.1.617.2 (Delta) and B.1.1.529 (Omicron) variants. Active surveillance was used to investigate reporting of adverse events post-booster dose of either of the licensed mRNA Comirnaty (Pfizer/BioNTech) or Spikevax (Moderna) vaccines in adult (17 years and older) recipients in central Italy. Eligible participants were enrolled and interviewed via phone using a structured questionnaire. Primary outcomes related to the occurrence of adverse events post-booster were stratified by vaccine, and frequency of local/systemic, mild/moderate/severe events. Of a total of 622 participants interviewed, 554 (89.1%) reported at least one adverse event (88.2% and 92.9% after the Comirnaty or Spikevax vaccine, respectively): 63.4% were female, and 78.5% aged 17 to 64 years, regardless of vaccine. 87.7% and 68.2% of all recipients described at least one local or systemic reaction, respectively: 97.3, 38.6 and 4.7% reported mild, moderate, or severe events, respectively. The most frequent adverse reactions were pain, redness, or swelling at the injection site and fatigue, while malaise and fever significantly occurred after the Comirnaty, and vomiting after the Spikevax booster. Compared to the primary vaccination, lymphadenopathy was more common after the booster (p < 0.001), especially after Comirnaty vaccine. The study findings revealed no serious or unexpected adverse events, and are in agreement with data available on booster dose for both mRNA vaccines. The transient, mild to moderate, and common to very common side reactions reported should be used to reassure potential recipients of the lack of safety concerns.

A SARS-CoV-2 Outbreak Among Nursing Home Residents Vaccinated with a Booster Dose of mRNA COVID-19 Vaccine.

This study describes a SARS-CoV-2 outbreak caused by the Delta (B.1.617.2) variant in a nursing home in Central Italy during October-November 2021. Trained interviewers collected data from residents, staff, and administration officers with an agreed informed consent procedure. Thirty-two (44.5%) out of 72 residents (median age 89 years) and six (26.1%) of 23 healthcare workers were found to be infected with SARS-CoV-2. Infections occurred more often among residents with a higher index of independence in daily living activities, suggesting an increased risk for those with more interactions. Twenty-five infected residents (78.1%) received the booster dose of mRNA anti-COVID-19 vaccine > 7 days before SARS-CoV-2 onset. Half of the infected residents had mild symptoms, and only three required hospitalisation, one of whom died from COVID-19 complications. The study underlines the effectiveness of a booster dose in providing a high protection against severe disease and hospitalisation even among vulnerable individuals infected with the Delta variant of concern.

Active Surveillance of Adverse Events in Healthcare Workers Recipients After Vaccination with COVID-19 BNT162b2 Vaccine (Pfizer-BioNTech, Comirnaty): A Cross-Sectional Study.

In this cross-sectional study, adverse events after the first and second dose of BNT162b2 mRNA (Pfizer-BioNTech, Comirnaty) vaccine against coronavirus disease 2019 were investigated among employees of clinics in central Italy. A 42-items questionnaire was administrated to vaccine recipients. Adverse events were classified based on severity and occurrence as reported in the literature. A descriptive/univariate analysis using Chi-square or Fisher's Exact tests was performed. Odds ratio (OR) and 95% confidence intervals were calculated to assess risk factors. 340 individuals (61.5% females; median age 49 years) participated. Adverse events were reported by 279 (82%) and 281 (82.6%) individuals as induced by the first and second dose, respectively. Mild reactions were mainly reported (80.9% and 80.3%), followed by moderate (11.8% and 37.1%) and severe (3.8% and 4.7%). Adverse events were identical to those already described as very common (81.8% and 80.6%), although vaccine-coincidental events not cited in the literature were reported by 6% and 15.6% following each dose. Age ≤ 55 years was a risk factor for any adverse event after each injection (ORs: 2.942 and 2.818), as well as female sex for those mild (ORs: 1.856 and 2.818) and common (ORs: 3.452 and 2.145). Findings were consistent with national reports as most of the adverse events were mild and associated with female sex and young age, while investigations are needed for reactions not described elsewhere. Data are useful to support the vaccine safety profile, also because largely targeted healthcare personnel more skilled than general population in self-diagnosis of health-related issues.

Awareness, knowledge and training gaps regarding asbestos among General Practitioners: a pilot study.

General Practitioners (GPs) have good knowledge of health status and sociocultural backgrounds of their patients, thus could be decisive in early detection of cases of asbestos-related diseases (ARDs). In this cross-sectional pilot study, we investigated perception and knowledge on asbestos risk amongst a sample of GPs practicing in Molise region, central Italy, who have anonymously completed a 29-items questionnaire specifically developed for this research. Based on GPs' answers, we obtained scores and classified awareness and knowledge into four percentage quartile classes including inadequate (0-24%), poor (25-49%), moderate (50-74%) and high (75-100%), and scarce (0-24%), sufficient (25-49%), good (50-74%) and optimal (75-100%), respectively. Twenty-eight GPs (median age 63 years; 82% male) participated. Perception and knowledge among participants varied from 62 to 84% and from 18 to 42%, respectively, with 65 and 42% showing an adequate level, respectively. Our survey revealed a satisfactory perception and knowledge of general features about this topic, while a poor awareness of detailed aspects, underlining the need of continuing medical education in the field of occupational medicine. The study remarks that criteria for ARDs diagnosis should be better specified, introducing a detailed list to harmonize medical protocols for symptoms identification and patients' examination. Hence, increasing awareness of asbestos risk and ARDs among GPs represents a crucial opportunity, because of their prominent position to promptly take care of patients and provide targeted information.

A Coronavirus Outbreak Linked to a Funeral Among a Romani Community in Central Italy.

Background: The epidemic dynamics of COVID-19 in the Molise region, central Italy, has dramatically changed from the beginning of May 2020, which was when infections were reported amongst Romani people. The aims of this study were to describe the characteristics of an outbreak that occurred in the Romani community and the interventions implemented for control. Methods: A retrospective analysis of outbreak data was performed to describe the SARS-CoV-2 transmission dynamics. Results: A young Romani woman was the first case reported and epidemiological investigation established a possible link with the funeral of a deceased member of this community. In total, 150 close contacts within 34 family groups in two cities were traced, and 109 (72.7%) Romani individuals were found to be infected by COVID-19. The patient's median age was 31 years, 58% were female, and the highest (20.2%) incidence occurred in the 0-9 years age group. A total of 26 (23.8%) patients developed typical SARS-CoV-2 symptoms, 15 (57.8%) were hospitalized, and 21 (22.1%) had comorbidities [most commonly hypertension (28.6%) and/or coronary heart diseases (23.8%)]. The outbreak was effectively controlled through compulsory quarantine and enhanced active surveillance. Conclusions: This is the first study providing insight into COVID-19 transmission dynamics among a Romani population living in Italy. These findings support general conclusions about the role of crowded social gatherings in SARS-CoV-2 spread, the high communicability among close contacts and household settings, and the impact of asymptomatic carriers. These features are of relevance to certain Romani customs where family gatherings are a fundamental pillar of their lives. Although difficulties emerged in interacting with Romani people related to cultural drivers, beliefs, and lifestyle, the outbreak management was effective and should be considered as a valuable model applicable to similar incidents occurring in minority populations.

Healthcare-Associated Infections and Antibiotics Consumption: A Comparison of Point Prevalence Studies and Intervention Strategies.

This study compares healthcare-associated infections (HAIs) prevalence and antimicrobial consumption (AMC) from surveys conducted in 2016 and 2019 in an Italian hospital for acute care. HAIs prevalence was 7.1% in both surveys, while patients were under antibiotic treatment slightly increased from 2016 to 2019, from 42.6% to 43.7%, respectively. In the survey of 2016, HAIs risk factors were fatal McCabe score and hospitalization longer than two weeks, while CVC and urinary catheter in that conducted in 2019. In both surveys, CVC and peripheral venous catheter resulted associated to AMC. HAIs and AMC remained stable although the hospital undergone a complexity reduction in the second survey, remarking that critical actions are strictly required implementing infection control practices and antimicrobial stewardship.

Precision Medicine and Public Health: New Challenges for Effective and Sustainable Health.

The development of high-throughput omics technologies represents an unmissable opportunity for evidence-based prevention of adverse effects on human health. However, the applicability and access to multi-omics tests are limited. In Italy, this is due to the rapid increase of knowledge and the high levels of skill and economic investment initially necessary. The fields of human genetics and public health have highlighted the relevance of an implementation strategy at a national level in Italy, including integration in sanitary regulations and governance instruments. In this review, the emerging field of public health genomics is discussed, including the polygenic scores approach, epigenetic modulation, nutrigenomics, and microbiomes implications. Moreover, the Italian state of implementation is presented. The omics sciences have important implications for the prevention of both communicable and noncommunicable diseases, especially because they can be used to assess the health status during the whole course of life. An effective population health gain is possible if omics tools are implemented for each person after a preliminary assessment of effectiveness in the medium to long term.

Pidotimod and Immunological Activation in Individuals Infected with HIV.

BACKGROUND: The improvements in HIV infection therapy and the large availability of antiretroviral drugs have led to an increased survival among HIV infected people, and simultaneously to a raised morbidity and mortality due to not-AIDS-related events in this group compared to the general population. An increased systemic inflammation and a persistent immune activation play a pivotal role in determining high rates of non-AIDS comorbidities. In the last years, many natural or synthetic immunomodulatory molecules acting by different mechanisms have been conceived. Pidotimod is a synthetic dipeptide molecule showing immunomodulatory properties. The aim of this pilot study was to evaluate the effects of Pidotimod supplementation on residual inflammation in HIV infected population. METHODS: Forty HIV positive individuals under cART were enrolled: 30 were treated with Pidotimod supplementation (study group) and 10 served as control group (without Pidotimod supplementation). For all participants, Cystatin C, PCR, ESR, microalbuminuria, TNF-α, INF-γ, IL-4, IL-10, IL1ß, IL-18 and IL-2 were measured at enrolment (T0), 4 weeks after of Pidotimod supplementation (T1), and 4 weeks after completing supplementation (T2). RESULTS: In HIV positive participants treated with Pidotimod, the evaluation of cytokine levels showed that IL-10, IFN gamma, and IL-4 were significantly higher at enrolment compared to the control group. The increase under Pidotimod treatment persisted after supplementation suspension, while the pro-inflammatory cytokines levels were reduced. Salivary IgA also increased during 4 weeks of supplementation and persisted at 4 weeks after completing supplementation. On the other hand, the Cystatin C and microalbuminuria levels decreased over time, at a greater extent the Cystatin C serum levels. CONCLUSION: The study findings showed that the HIV population receiving Pidotimod achieved a rebalancing of pro-inflammatory and anti-inflammatory cytokines as well as a significant reduction in cystatin C levels. The treatment further allowed for an increase in salivary IgA levels at all the analyzed times, as a secondary event to a remodulation of the immunological status obtained with pidotimod. This approach could represent a new way to design new intervention strategies aimed at improving the persistent immune activation status in the virologically suppressed HIV population.

Carbapenem-Resistant KPC- and TEM-Producing Escherichia coli ST131 Isolated from a Hospitalized Patient with Urinary Tract Infection: First Isolation in Molise Region, Central Italy, July 2018.

In July 2018, a Klebsiella pneumoniae carbapenemase (KPC)-producing Escherichia coli ST131 was isolated from a patient admitted to the Vascular Surgery Unit of the main hospital of Molise region, Central Italy. Sequencing and alignment with the available sequences revealed that the isolate harbored the KPC-2 variant and TEM-1 beta-lactamase. This observation raises great concerns about the spread of carbapenem resistance in national and local settings with high endemicity level of KPC in K. pneumoniae, and underlines the importance of strengthening a proactive surveillance.

Human Papillomavirus Infections, Cervical Cancer and MicroRNAs: An Overview and Implications for Public Health.

Human Papillomavirus (HPV) is among the most common sexually transmitted infections in both females and males across the world that generally do not cause symptoms and are characterized by high rates of clearance. Persistent infections due at least to twelve well-recognized High-Risk (HR) or oncogenic genotypes, although less frequent, can occur, leading to diseases and malignancies, principally cervical cancer. Three vaccination strategies are currently available for preventing certain HR HPVs-associated diseases, infections due to HPV6 and HPV11 low-risk types, as well as for providing cross-protection against non-vaccine genotypes. Nevertheless, the limited vaccine coverage hampers reducing the burden of HPV-related diseases globally. For HR HPV types, especially HPV16 and HPV18, the E6 and E7 oncoproteins are needed for cancer development. As for other tumors, even in cervical cancer, non-coding microRNAs (miRNAs) are involved in posttranscriptional regulation, resulting in aberrant expression profiles. In this study, we provide a summary of the epidemiological background for HPV occurrence and available immunization programs. In addition, we present an overview of the most relevant evidence of miRNAs deregulation in cervical cancer, underlining that targeting these biomolecules could lead to wide translational perspectives, allowing better diagnosis, prognosis and therapeutics, and with valuable applications in the field of prevention. The literature on this topic is rapidly growing, but advanced investigations are required to achieve more consistent findings on the up-regulated and down-regulated miRNAs in cervical carcinogenesis. Because the expression of miRNAs is heterogeneously reported, it may be valuable to assess factors and risks related to individual susceptibility.

Molecular Epidemiological Insights into Colistin-Resistant and Carbapenemases-Producing Clinical Klebsiella pneumoniae Isolates.

PURPOSE: Carbapenemases-producing Klebsiella pneumoniae are challenging antimicrobial therapy of hospitalised patients, which is further complicated by colistin resistance. This study describes molecular epidemiological insights into colistin-resistant and carbapenemases-producing clinical K. pneumoniae. PATIENTS AND METHODS: Cultures collected from 26 hospitalised patients during 2014-2017 in the main hospital in Molise Region, central Italy, were characterized. The minimum inhibitory concentration for 19 antibiotics was determined, including carbapenems and colistin. Prevalence of resistance-associated genes was investigated through PCR, detecting bla KPC, bla GES, bla VIM, bla IMP, bla NDM, bla OXA-48, bla CTX-M, bla TEM, bla SHV, and mcr-1,2,3,4,5,6,7,8. The mgrB gene was also analysed in colistin-resistant strains by PCR and sequencing assays. K. pneumoniae were typed by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). RESULTS: Twenty out of 26 K. pneumoniae were phenotypically resistant to carbapenems and 19 were resistant to colistin. All isolates harbored bla KPC, and bla SHV, bla TEM and bla VIM were further the most common resistance-associated genes. In colistin-resistant strains, mcr-1,2,3,4,5,6,7,8 variants were not detected, while mutations and insertion elements in mgrB were observed in 68.4% (n=13) in 31.6% (n=6) isolates, respectively. PFGE revealed 12 clusters and 18 pulsotypes at 85% and 95% cut-off, while the Sequence Types ST512 (n=13, 50%), ST101 (n=10, 38.5%), ST307 (n=2, 7.7%) plus a novel ST were detected using MLST. CONCLUSION: All K. pneumoniae showed a multidrug-resistant phenotype, particularly to carbapenems and colistin. According to national data, bla KPC was the prevailing carbapenemase, followed by bla VIM, while bla TEM and bla SHV were among the most frequent beta-lactamases. Consistent with previous reports in Italy, ST512 was the most common clone, particularly during 2014-15, whilst ST101 became dominant in 2016-17. Colistin resistance was mainly associated with deleterious mutations and transposon in the mgrB gene. Improvements of surveillance, compliance with infection prevention procedures and antimicrobial stewardship are essential to limit the spread of resistant K. pneumoniae.

Characterization of Listeria monocytogenes serovar 1/2a, 1/2b, 1/2c and 4b by high resolution melting analysis for epidemiological investigations.

This study aimed to characterize serovar 1/2a, 1/2b, 1/2c and 4b of Listeria monocytogenes cultures based on High Resolution Melting (HRM) profiles, targeting 53 fragments in the region comprising prs, Listeria Pathogenicity Island-1 (LIPI-1) and ldh loci, and 28 fragments of inlAB operon. Fifty L. monocytogenes cultures (28 of lineage I, 22 of lineage II) were tested. Real time PCR and EvaGreen-based HRM assays were performed, and the HRM profile for each amplicon was compared to that of L. monocytogenes EGD-e strain. Considering all fragments tested, 45 HRM profiles were identified (Diversity Index = 99.35). Similarity analysis identified two main clusters: the first consisted of 25 cultures, including all 1/2a and 1/2c strains, except for three isolates from food of serovar 4b; the second group only included 1/2b and 4b isolates. Eighteen out of targeted amplicons showed constant HRM characteristics irrespective of the serovar/lineage, and hlyA displayed the most stable melting behavior. Conversely, thirteen amplicons were specific for 1/2b and 4b isolates, showing major variations within actA, followed by prs, prfA, mpl and plcB genes. A fragment targeting an intragenic region (part of plcA and part of an unknown gene) had a melting profile allowing differentiation between 4b and 1/2b isolates showing different Tm variants. Amplicons of inlA and inlB exhibited the largest intra-strain melting differences, and one inlB fragment could allow discriminating between 4b and 1/2b cultures, as well as between lineages. A greater level of genetic diversity amongst 1/2a cultures compared to 1/2c, 1/2b and 4b isolates was observed, with variations identified in LIPI-1, as well as within inlA and inlB genes. Sequencing analysis of amplicons with differential HRM profile from EGD-e confirmed point mutations. The study findings underlines that HRM-based approach may be useful for bacterial subtyping for epidemiological purposes when sequencing-based methods are not available.

Healthcare-associated infections point prevalence survey and antimicrobials use in acute care hospitals (PPS 2016-2017) and long-term care facilities (HALT-3): a comprehensive report of the first experience in Molise Region, Central Italy, and targeted intervention strategies.

BACKGROUND: Healthcare associated infections (HAIs) are a major public health concern both in acute hospitals and long-term care facilities (LTCFs), considering the clinical presentations and related costs. The study describes the first regional experience on HAIs and antimicrobials consumption obtained through point prevalence survey (PPS) 2016-2017 in the "Antonio Cardarelli" acute hospital, and in the LTCF of Larino municipality (Healthcare-associated infections and Antimicrobial use in European Long-Term care facilities, HALT-3) of Molise Region, Central Italy, both coordinated by the European Center for Disease Control (ECDC). METHODS: PPS was carried out during 24-26 November 2016, while HALT-3 on 29 June 2017. Standardized protocols and software provided by ECDC were used to collect facilities information, patients/residents, HAIs and antibiotic consumption data. RESULTS: An active HAI was found in 16 (7.1%) of 224 admitted patients in the acute hospital, and 50% occurred in a clinical specialty ward. Bundles, checklist for HAIs prevention and antimicrobial stewardship were lacking. Among 29 LTCF residents the HAIs prevalence was 3.4%. Surveillance programs for HAIs and antimicrobial stewardship strategy were not available. CONCLUSION: The overall results identified the need and types of interventions to be implemented in both settings, either at organizational or individual level, to improve antibiotic prescription practice and limit risk factors involved in potentially preventable infections.

[Biological risk in agriculture and construction workplaces: a survey on perception, knowledge and prevention measures.] / Il rischio biologico nei lavoratori dei settori agricoltura ed edilizia: percezione, conoscenze e misure di prevenzione.

OBJECTIVES: Despite the potential presence in many workplaces, biological risk is little known and largely underestimated, except in healthcare environments. Objectives: To evaluate perception, knowledge and behaviors adopted for protection and prevention of biological risk, related also to the occupational activity, among construction and agricultural workers. METHODS: Workers were recruited at farms and construction companies of Molise Region, Central Italy, which were visited within the surveillance activities planned by local institutions. A questionnaire was administered to workers to collect sociodemographic and occupational data, and concerning risk perception and knowledge, and awareness of available prevention measures, also related to the work activity. RESULTS: total of 143 workers (73.4% males, 42.9±10.7 years old) were interviewed, and 56.6% were construction workers. Only 24% of workers believed that infectious diseases could be frequent and health threatening in carrying out the work activities; half of them declared to be exposed to biological hazards, but 70% were unworried. An underestimation of the severity of some pathologies, such as listeriosis, leptospirosis and viral hepatitis emerged, and only 70% of workers believed that tetanus is highly or very highly dangerous for health. Furthermore, 33% of workers said to have scarce or insufficient knowledge of biological risk, and 97.2%, 80.4% and 45.5% were aware that a vaccine is available for tetanus, hepatitis B and A, respectively. All workers undergone the tetanus vaccination and 39.2% the anti-hepatitis B. CONCLUSIONS: Despite the high probability of exposure to biological agents, the results of the survey revealed a lack of perception and knowledge of the risk, as well as a poor awareness of available preventive measures among construction and agricultural workers. These data point out the need to activate information and training programs on exposure to biological agents and on both emerging and re-emerging infectious diseases potentially related to work activities, and to provide prevention procedures specific for these workplaces.
