RESUMEN
OBJECTIVES: This study aimed to assess the impact of the COVID-19 pandemic on national surveillance of viral hepatitis in Italy. STUDY DESIGN: Interrupted time series analysis. METHODS: Using an interrupted time series analysis with a customised AutoRegressive Integrated Moving Average model on hepatitis cases reported to the Integrated Epidemiological System of Acute Viral Hepatitis from 2006 to 2022, we examined trends in incidence, time to diagnosis and time to epidemiological investigations for hepatitis A, hepatitis B and hepatitis C. RESULTS: The quarterly incidence of hepatitis B (-0.251, P = 0.05) and hepatitis C (-0.243, P = 0.003) significantly decreased with the onset of the pandemic. Surveillance times for hepatitis B (5.496, P < 0.001) and hepatitis C (35.723, P < 0.001), measured as days lost per quarter, significantly increased 12 and 24 months after the pandemic's start. This aligns with a notable rise in quarterly incidence at 36 months for both (0.032, P = 0.030 for hepatitis B; 0.040, P < 0.001 for hepatitis C). CONCLUSIONS: The decrease in reported cases could be due to an increase in infection prevention control and containment measures put in place in a pandemic context. However, a delay in the initiation of epidemiological investigations was observed, which could lead to a further increase in incidence in the future.

BACKGROUND: It is unknown whether COVID-19 patients are at higher risk due to demographic and clinical characteristics associated with higher COVID-19 infection risk and severity of infection, or due to the disease and its management. AIM: To assess the impact of COVID-19 on healthcare-associated infection (HAI) transmission and antimicrobial use (AMU) prevalence during the later stages of the pandemic. METHODS: A point-prevalence survey (PPS) was conducted among 325 acute care hospitals of 19 out of 21 Regions of Italy, during November 2022. Non-COVID-19 patients were matched to COVID-19 patients according to age, sex, and severity of underlying conditions. HAI and AMU prevalence were calculated as the percentage of patients with at least one HAI or prescribed at least one antimicrobial over all included patients, respectively. FINDINGS: In total, 60,403 patients were included, 1897 (3.14%) of which were classified as COVID-19 patients. Crude HAI prevalence was significantly higher among COVID-19 patients compared to non-COVID-19 patients (9.54% vs 8.01%; prevalence rate ratio (PRR): 1.19; 95% confidence interval (CI): 1.04-1.38; P < 0.05), and remained higher in the matched sample; however, statistical significance was not maintained (odds ratio (OR): 1.25; 95% CI: 0.99-1.59; P = 0.067). AMU prevalence was significantly higher among COVID-19 patients prior to matching (46.39% vs 41.52%; PRR: 1.21; 95% CI: 1.11-1.32; P < 0.001), and significantly lower after matching (OR: 0.77; 95% CI: 0.66-0.89; P < 0.001). CONCLUSION: COVID-19 patients could be at higher HAI risk due to underlying clinical conditions and the intensity of healthcare needs. Further efforts should be dedicated to antimicrobial stewardship among COVID-19 patients.

Background: Healthcare-associated infections (HAIs) and multidrug resistance (MDR) are a growing public health threat and pose a risk to patient safety in healthcare facilities. Vancomycin-resistant Enterococci (VRE) are responsible for nosocomial infections and have intrinsic and acquired resistance to many antibiotics, including glycopeptides. VRE carriage can remain undetected, increasing the risk of contact transmission. Identifying colonized patients is crucial for the implementation of preventive measures. Aims: The aims of this study were to evaluate the trend of VRE carriage based on rectal swab results between 2019 and February 2022 in a large Italian trust and the percentage of patients with VRE colonization at the time of hospitalization. Methods: This was a retrospective observational study based on results of rectal swabs performed for screening on admission between January 2019 and February 2022 in four hospitals part of a single trust in Turin, North-Western Italy. The study collected data on the date of specimen collection, type of specimen, isolated pathogen and the date of hospital admission. Descriptive analysis of data was performed, and duplicate samples were not considered. Results: From January 2019 to February 2022 we collected 5025 rectal swabs performed in hospitals of the trust, of which 3037 were performed in 2019 (60%), 741 in 2020 (15%), 611 in 2021 (12%) and 636 in the first two months of 2022 (13%). VRE positivity was found in 162 (3%) rectal swabs, of which 2 cases in both 2019 (0.1%) and 2020 (0.3%), 95 in 2021 (15.5%) and 63 in the first two months of 2022 (9.9%). Furthermore, 52% (84/162) of positive rectal swabs were performed at admission, whereas the remaining 48% (78/162) of positive rectal swabs were performed after 48h. Conclusions: This study found an increasing trend of VRE carriage in the study population during the SARS-CoV-2 pandemic, highlighting the importance of screening patients for VRE carriage to prevent worsening clinical conditions, environmental contamination, and prolonged hospitalization.

BACKGROUND: Healthcare-associated infections (HAIs) represent a major Public Health issue. Hospital-based prevalence studies are a common tool of HAI surveillance, but data quality problems and non-representativeness can undermine their reliability. METHODS: This study proposes three algorithms that, given a convenience sample and variables relevant for the outcome of the study, select a subsample with specific distributional characteristics, boosting either representativeness (Probability and Distance procedures) or risk factors' balance (Uniformity procedure). A "Quality Score" (QS) was also developed to grade sampled units according to data completeness and reliability. The methodologies were evaluated through bootstrapping on a convenience sample of 135 hospitals collected during the 2016 Italian Point Prevalence Survey (PPS) on HAIs. RESULTS: The QS highlighted wide variations in data quality among hospitals (median QS 52.9 points, range 7.98-628, lower meaning better quality), with most problems ascribable to ward and hospital-related data reporting. Both Distance and Probability procedures produced subsamples with lower distributional bias (Log-likelihood score increased from 7.3 to 29 points). The Uniformity procedure increased the homogeneity of the sample characteristics (e.g., - 58.4% in geographical variability). The procedures selected hospitals with higher data quality, especially the Probability procedure (lower QS in 100% of bootstrap simulations). The Distance procedure produced lower HAI prevalence estimates (6.98% compared to 7.44% in the convenience sample), more in line with the European median. CONCLUSIONS: The QS and the subsampling procedures proposed in this study could represent effective tools to improve the quality of prevalence studies, decreasing the biases that can arise due to non-probabilistic sample collection.

BACKGROUND: Healthcare-associated infections (HAIs) are an increasing public health threat. Measuring disease burden in disability-adjusted life-years (DALYs) allows the combination of morbidity and mortality into one figure, as it represents the summation of years lived with disability and years of life lost. AIM: To evaluate the incidence, attributable deaths and burden of the most significant HAIs in Italy. METHODS: Prevalence data from the study sample of the 2016 national Point Prevalence Survey of HAIs in acute-care settings were used to estimate the incidence of five HAIs. The methodology from the Burden of Communicable Diseases in Europe (BCoDE)-project was employed for DALY calculations, adapting the disease models to the Italian population. FINDINGS: We estimated a total of 641,065 (95% uncertainty interval, UI 585,543.00-699,207.90) new yearly cases of HAIs and 29,375 (95% UI 23,705.97-35,905.80) deaths in Italy in 2016. The total annual DALYs were estimated to be 424,657.45 (95% UI 346,240.35-513,357.28), corresponding to 702.53 DALYs (95% UI 575.22-844.66) per 100,000 general population. Bloodstream infections accounted for the majority of total DALYs (59%), healthcare-associated pneumonia for 29%, surgical site infections for 9%, CDI for 2% and urinary tract infections accounted for less than 1% of total DALYs. CONCLUSION: Results of this study suggest HAIs have a substantial burden in Italy. Reducing the burden of HAIs through infection prevention and control efforts is an achievable goal. This study provides data that could be used to guide policy-makers in the implementation of these measures.

BACKGROUND: Heater-cooler units (HCUs) used during cardiopulmonary bypass may become colonized with non-tuberculous mycobacteria (NTM), including Mycobacterium chimaera. Recently, a worldwide investigation conducted in hospitalized infected patients has detected M. chimaera in several Stockert 3T HCUs manufactured by LivaNova. AIM: Microbiological surveillance on Stockert 3T (LivaNova) and Maquet HCU40 (Getinge) devices as well as an evaluation of the efficacy of their recommended decontamination protocols. METHODS: A total of 308 water samples were collected from 29 HCUs: 264 samples were collected from 17 Stockert 3T HCUs and 44 samples from 12 Maquet HCU40 devices. Samples were tested for total viable counts (TVCs) at both 22 and 36°C, Pseudomonas aeruginosa, coliform bacteria, and NTM. The microbiological surveillance began in June 2017 and ran until October 2019. FINDINGS: A total of 308 HCU water samples were analysed, 65.5% of which yielded NTM. The most frequently colonized device with NTM was the Stockert 3T (88.2%), with a frequency of positive samples of 59.5% (157/264). The Maquet HCU40 devices less frequently yielded NTM (33.3%), with a frequency of positive water samples of 13.6% (6/44). Disinfection procedures were effective in reducing TVCs of bacteria with the exception of NTM species. NTM were detected in both pre-disinfection (50.1%) and post-disinfection (55.7%) samples, and no significant association was found between disinfection and NTM results both in Stockert 3T and Maquet HCU40 devices. CONCLUSION: This study suggests that manufacturers' procedures for disinfection are ineffective and/or inadequate. Until effective disinfection protocols become available, the only way to minimize the risk of NTM contamination is to closely monitor the water quality in the HCU, keep it as clean as possible, and treat it like any other biohazardous material.

BACKGROUND: On March 11, 2020, the World Health Organization characterized the novel coronavirus disease 2019 (COVID-19) outbreak as a pandemic. The first cases in Italy were reported on January 30, 2020, and the outbreak quickly escalated. On March 19, 2020, deaths in Italy surpassed those in China. The Italian government implemented progressively restrictive measures leading to a nationwide lockdown on March 8, 2020. This study aimed to assess the impact of mitigation measures implemented in Italy on the spread of COVID-19. METHODS: Publicly available data were used to evaluate changes in the growth curve of the number of patients hospitalized in intensive care (IC) at three time intervals between February 19, 2020, and April 9, 2020, after the implementation of progressive measures: (1) containment and travel restrictions, (2) lockdown of the epicenter of the outbreak, and (3) school closures and nationwide lockdown. The models that showed the highest reliability according to the Akaike information criterion and based on data from the three time intervals were projected to assess how the epidemic would have evolved if no other measure had been implemented. RESULTS: The most reliable models were (1) exponential, (2) quadratic, and (3) cubic (R2 = 0.99, >0.99, and > 0.99 respectively), indicating a progressive decrease in the growth of the curve. CONCLUSION: This study suggests the measures were effective in flattening the epidemic curve and bought valuable time, allowing for the number of IC beds to be nearly doubled before the national health system reached maximum capacity.

BACKGROUND: Invasive non-tuberculous mycobacteria (NTM) infections are emerging worldwide in patients undergoing open-chest cardiac bypass surgery exposed to contaminated heater-cooler units (HCUs). Although this outbreak has been investigated by culturing bacteria isolated from HCU aerosol and water samples, these conventional methods have low-analytic sensitivity, high rates of sample contamination, and long turnaround time. AIM: To develop a simple and effective method to detect NTM in HCUs by real-time polymerase chain reaction (PCR), with a short laboratory turnaround time and reliable culture results. METHODS: A total of 281 water samples collected from various HCUs at seven Italian hospitals were simultaneously screened for NTM by a propidium monoazide (PMA)-PCR assay and by conventional culture testing. The results were analysed with culture testing as the reference method. FINDINGS: (i) The agreement between culture testing and PMA-PCR was 85.0% with a cycle threshold (CT) cut-off value of <38 vs 80.0% with a CT of <43, with a moderate Cohen's κ-coefficient; (ii) the CT cut-off value of <42 was deemed more suitable for predicting positive specimens; (iii) given the low concentration of target DNA in water samples, the minimum volume to be tested was 1 L. CONCLUSION: The use of PMA-PCR for fast detection of NTM from environmental samples is highly recommended in order to ascertain whether HCUs may represent a potential source of human exposure to NTM. This reliable and simple method reduces laboratory turnaround time compared to conventional methods (one to two days vs eight weeks, respectively), thereby improving control strategies and effective management of HCUs.

BACKGROUND: Awareness of healthcare-associated infections (HAIs) and antimicrobial use in long-term care facilities (LTCFs) is increasing. In 2017, the third national point prevalence survey (PPS) was conducted in Italy as part of the third 'Healthcare-Associated Infections in European Long-Term Care Facilities' (HALT3) study. AIM: To report the results of HALT3 and analyse the resident population of LTCFs, implementation of good practices, prevalence of infections and antimicrobial use. METHODS: The survey was designed as a PPS, carried out from April to June 2017. All residents who lived full-time in the institution were included. All facilities were asked to complete an institutional questionnaire, a ward list for all residents, and a resident questionnaire for those residents presenting with signs/symptoms of active infection and/or receiving an antimicrobial agent. FINDINGS: In total, 418 facilities took part in the study; 24,132 residents were eligible, and most were aged >85 years, disoriented and incontinent. The prevalence of HAIs was 3.9%, and 50% of the institutions reported that they had a professional trained in infection control on their staff. Only 26.4% of infections were confirmed by a microbiological sample, and 26.9% of the isolated micro-organisms were resistant to at least one antimicrobial class. In total, 1022 residents received at least one antimicrobial agent, and cephalosporins were prescribed most commonly. CONCLUSION: The number of infection control and antimicrobial stewardship measures implemented was found to be considerably higher in this study compared with previous studies. This could lead to a reduction in the prevalence of HAIs, antimicrobial use and antimicrobial resistance. Further studies are needed to monitor these aspects.

BACKGROUND: Antimicrobial stewardship programs and comprehensive infection control programs represent the main strategies to limit the emergence and transmission of multi-drug resistant bacteria in hospital settings. The purpose of this study was to describe strategies implemented in Italian children's hospitals for controlling antibiotic resistance. STUDY DESIGN: Cross sectional multicenter study. METHODS: Four tertiary care Italian children's hospitals were invited to participate in a survey aimed at collecting information on activities implemented as of December 2015 using a self-administered online questionnaire. The questionnaire was divided in three sections focalizing on: i) policies for prevention and control of hospital-acquired infection, ii) prevention and control of multi-drug resistant bacteria, and iii) antibiotic prescribing policies and Antimicrobial stewardship programs. Questionnaires were compiled between May and July 2016. RESULTS: All hospitals had multidisciplinary infection control committee, procedures on hand hygiene, isolation measures, disinfection/sterilization, waste disposal and prevention on infections associated to invasive procedures. All sites screened patients for multi-drug resistant bacteria colonization in selected units, and adopted contact precautions for colonized patients. Screening during hospitalization, or in case of infections in the same ward were not universally implemented. All hospitals had policies on surgical prophylaxis, while policies on medical prophylaxis and treatment of bacterial infections varied among sites. Two sites recommended to review the appropriateness of antibiotic prescribing after 48-72 hours and one recommended de-escalation therapy. CONCLUSIONS: This study highlighted several areas of improvement, such as actions for screening patients in case of occurrence of multi-drug resistant bacteria, antimicrobial stewardship programs and implementation of policies targeting antibiotic prescriptions for therapeutic purposes and medical prophylaxis.

The creation of guidelines is a methodologically complex activity that requires technical expertise, resources and time. Methods of guideline production must meet at least these three criteria: multidisciplinarity, systematic review, and ranked recommendations. In May 2015, the new "Guidelines for the prevention and control of Legionnaire's disease" were published on the website of the Italian Ministry of Health in order to "gather, update and integrate in a single document all the previous national recommendations published". The critical review of the document has led us to conclude that this document does not comply with these three criteria, and we emphasize that guidelines should make decision-making easier, considering the various scientific approaches to a health problem and choosing the one considered most effective. Therefore, the persons responsible for the development of guidelines should strive to widely adopt and use current standards for the development of guidelines as a means to improve patient care and health outcomes.

Monensin and functional oils (FO) were supplemented to a high-concentrate diet abruptly fed to 12 ruminally cannulated Zebu steers to study their effects on rumen fermentation, blood metabolites, and , , and relative population. A randomized complete block design with repeated measures over time within 2 experimental periods of 21 d each was used. Treatments were a control (CTR; with no additives), FO (included at 400 mg/kg), and monensin included at 30 mg/kg (M30) or 40 mg/kg (M40). All steers were fed the same high-concentrate basal diet, which consisted of 92.25% concentrate. The first 60 h after transition showed a treatment and hour interaction for ruminal propionate proportion ( = 0.028), and no change in acetate molar proportion ( = 0.633), rumen pH ( = 0.370), and time the rumen pH remained below 5.6 ( = 0.242) were observed. The acetate:propionate ratio decreased ( = 0.020) when monensin was fed in both concentrations (2.30 for the M30 treatment and 2.32 for the M40 treatment) compared with when the CTR was fed (2.85), without being different when the FO (2.71) treatment was fed. Only the M30 treatment did not show pH below 5.2 (P=0.047) over the 60 h after the abrupt transition. Within the entire period, DMI ( = 0.008) and mean ruminal pH ( = 0.040) as well as molar proportions of propionate ( = 0.034) and valerate ( = 0.031) had significant interactions between treatment and day. Total VFA concentration was greater ( = 0.017) for the M30 (117.36 m) and CTR treatments (115.77 m) compared with the M40 treatment (105.02 m), without being different for the FO treatment (111.55 m). Treatments did not change feed behavior parameters. Blood HCO ( = 0.006) and total carbon dioxide ( = 0.003) were greater for the M30 (27.8 and 29.3 mmol/L, respectively) and FO treatments (28.3 and 29.7 mmol/L, respectively) compared with the CTR treatment (25.7 and 26.9 mmol/L, respectively). ( < 0.0001) and ( < 0.0001) decreased their population throughout days, whereas ( = 0.026) increased its population. Independent of ciliated protozoa genera, the greatest ( < 0.0001) protozoa counts were observed for the CTR treatment (52.7 × 10/mL), intermediate for the FO treatment (35.3 x10/mL), and least for steers fed monensin in both concentrations (15 × 10/mL for the M30 treatment and 14 × 10/mL for the M40 treatment). Feed additives had different effects to reduce the subacute acidosis. The use of the FO and M40 treatments did not change most of the rumen fermentation variables, especially in the first week after abrupt transition, when the M30 treatment provided higher protection against acidosis.

INTRODUCTION: The aim of the presents study was to compare the level of knowledge about Human Papilloma Virus (HPV) in vaccinated and non-vaccinated girls and to highlight the reasons why non-vaccinated girls refuse vaccination. METHODS: A cross-sectional study was conducted from October 2012 to June 2013 in Turin (Piemonte Region, Italy). Questionnaires were administered to girls attending secondary and high schools randomly selected. RESULTS: A total of 576 were compiled. The principle sources of information were parents and health workers. The main reported reasons for non-adherence to vaccination were the disagreement of the parents among the 11-12 years group (45.3%) and the lack of evidence on efficacy among the 18 years group (26.8%). By comparing the level of knowledge there was a statistically significant difference between groups: vaccinated girls reported higher score than the unvaccinated group in several questions (p ≤ 0.05). CONCLUSIONS: Our findings show a lack of information about HPV infection. Parents, school and health care workers have a central role in girl's education and choices about HPV vaccination. The communication campaign for the prevention of cervical cancer must therefore be characterised by messages able to clarify and consolidate messages that may have been partially received or misunderstood.

In 2008, Piedmont region, Italy, recommended delivering written information on healthcare-associated infection (HCAI) to every patient admitted to hospitals. We interviewed 363 patients admitted to five hospitals to evaluate whether patients who received written information were more informed about HCAI than the other patients. We found no statistically significant difference between the two groups. We did observe that knowledge of HCAI was significantly lower among women and significantly higher among patients with higher education and those admitted to a surgical ward.

We assessed the persistence of hepatitis B surface antigen antibody (anti-HBs) and immune memory in a cohort of 571 teenagers vaccinated against hepatitis B as infants, 17 years earlier. Vaccinees were followed-up in 2003 and in 2010 (i.e. 10 years and 17 years after primary vaccination, respectively). When tested in 2003, 199 vaccinees (group A) had anti-HBs <10 mIU/mL and were boosted, 372 (group B) were not boosted because they had anti-HBs ≥10 mIU/mL (n = 344) or refused booster (n = 28) despite anti-HBs <10 mIU/mL. In 2010, 72.9% (416/571) of participants had anti-HBs ≥10 mIU/mL (67.3% in group A vs. 75.8% in group B; p 0.03). The geometric mean concentrations (GMCs) were similar in both groups. Between 2003 and 2010, anti-HBs concentrations in previously boosted individuals markedly declined with GMC dropping from 486 to 27.7 mIU/mL (p <0.001). Fifteen vaccinees showed a marked increase of antibody, possibly due to natural booster. In 2010, 96 individuals (37 of group A and 59 of group B) with anti-HBs <10 mIU/mL were boosted; all vaccinees of the former group and all but two of the latter had an anamnestic response. Post-booster GMC was higher in group B (895.6 vs. 492.2 mIU/mL; p 0.039). This finding shows that the immune memory for HBsAg persists beyond the time at which anti-HBs disappears, conferring long-term protection.

BACKGROUND: A point prevalence survey (PPS) was conducted in Italy in 2010, as part of the first European PPS in Long Term Care Facilities (LTCFs), conducted within the HALT Project. METHODS: The PPS was aimed at estimating the prevalence of infections, antimicrobial resistance, and antibiotic use and to assess the status of infections control programs in this setting. RESULTS: Ninety two LTCFs, located in 11 different Italian regions, participated to the study: 9391 residents were enrolled, 9285 of whom were eligible according to the study criteria. The prevalence of residents with signs/symptoms of infection was 6.5% (606 residents); 438 residents were on antimicrobial treatment (4.7%) and 526 had signs/symptoms (5.7%) but in 324 residents only (3.5/100 residents) the infection satisfied the modified McGeer criteria and was considered confirmed. The most frequent infection site was the respiratory tract (1.27/100 residents). Mostly of the antibiotics were prescribed for respiratory tract infections (42.8% of the antibiotics) and for urinary tract infections (26.6%). The most frequently prescribed classes were quinolones, followed by penicillin plus beta-lactamase inhibitor and 3rd generation cephalosporins. Few infection had a microbiological confirmation, but among the 143 isolated microorganisms 24% were multidrug resistant. CONCLUSIONS: The burden of infections and antimicrobial resistance in LTCFs is significant and infection control and surveillance program are urgently needed.

SUMMARYA prospective cohort study with a 1-year telephone follow-up was performed to estimate the incidence of surgical-site infections (SSIs) in hip and knee prostheses. Twenty-five public hospitals equipped with orthopaedic units in two Italian regions were involved. An 8-month surveillance period was set to obtain significant data at a regional level and data were collected by the infection control nurses of each centre. One-year follow-up was completed in 75% of cases. SSIs were recorded in 45 cases (incidence rate 1·9/100 person-years, 95% CI 1·4-2·5). Thirty-six percent of SSIs were diagnosed during hospitalization and 95·3% within 90 days post-operation. This incidence is similar to that reported by European and USA surveillance systems. The proposed investigative method proved to be reliable and feasible. A prolonged surveillance for at least 3 months post-operation yields a good estimate of SSI in joint replacements.

Uveitis is a complex intraocular inflammatory disease resulting from several aetiological entities that are linked to geographical, genetic and socioeconomic variables. The purpose of this study was to provide an overview of the distribution patterns of uveitis as seen in a nationwide referral centre at a community hospital in Reggio Emilia, northern Italy, and to compare our data with those reported in previously published international series. The records of 1064 patients of Italian origin with uveitis referred to the Immunology Ocular Unit of the Arcispedale S. Maria Nuova Hospital in Reggio Emilia from 2002 to 2008 were classified and analysed. Data regarding sex, race, residence, age at presentation and at onset of uveitis, ocular involvement, clinical characteristics, ocular condition, and systemic disease associations were collected. The mean age at onset of uveitis was 41 years (range: 1-94), and the male-to-female ratio was 1:1.2. Anterior uveitis was the most common location (51.2%), followed by posterior uveitis (23.4%), panuveitis (19.6%), and intermediate uveitis (5.8%). The most frequent entities included Fuchs uveitis (22.7%), herpetic anterior uveitis (9.9%), toxoplasmosis (6.9%), HLA-B27-associated anterior uveitis (5.3%), and Behçet's disease (5.3%). The distribution we observed of the most common disease entities conformed to previous international series. In our series, Fuchs uveitis represented the most common diagnosis (22.7%, 45% of anterior uveitis). The high percentage of specific diagnosis (74%) can be explained by the establishment of new disease categories over time as well as by a systematic multi-disciplinary diagnostic approach.
