A territory-wide opportunistic, hospital-based HCV screening in the general population from northern Italy: The 1969-1989 birth-cohort.

BACKGROUND AND AIM: The World Health Organization (WHO) goal of Hepatitis C Virus (HCV) elimination by 2030 rose awareness about the need of screening plans, worldwide. In Italy, graduated screening starting from people born in 1969-1989 might be the most-effective strategy. We performed an opportunistic HCV screening study in the general population attending health facilities in Lombardy region, Northern Italy. METHODS: This is a prospective, multicenter, territory-wide, opportunistic study supported by the Regional Government of Lombardy, Italy. Between June 2022 and December 2022, all subjects born in 1969-1989, hospitalized or accessing blood collection centres were offered anti-HCV and HCV-RNA tests. Patients with known anti-HCV positivity and/or previous anti-HCV treatment were excluded. Demographic features were uploaded into a regional web-based platform. RESULTS: In total, 120 193 individuals were screened in 75 centres. Mean age was 44 (±6) years, 65.2% were females, 83.7% were tested at blood collection centres. Anti-HCV tested positive in 604 (0.50%) subjects: mean age 47 (±5), 51.1% females. HCV seroprevalence was higher in males (p < 0.00001), elderly (p < 0.00001) and in- vs. outpatients (p = 0.0009). HCV-RNA was detectable in 125 out of 441 (28.3%) anti-HCV positive subjects. Actively infected patients were 46 (±6) years old, mainly males (56.8%). The overall prevalence of active HCV infection was 0.10%, higher in elderly (p = 0.0003) and in in-patients (p = 0.0007). Among 93 HCV-RNA positive patients, the median age was 48 years, 58% males, 62% Italian born, median HCV-RNA levels were 6,1 log IU/mL, liver stiffness measurement (LSM) values 5.5 (3.1-29.9) kPa and ALT levels 48 U/L. CONCLUSIONS: The prevalence of active HCV infection in the 1969-1989 population attending health facilities in Lombardy was low. Most viremic patients were Italian-born, with mild liver disease but high-HCV-RNA levels. Due to the higher prevalence in the elderly, the extension of such opportunistic screening programs to lower birth cohorts would be warranted.

Adherence to Mediterranean Diet and Risk of Pancreatic Cancer: Systematic Review and Meta-Analysis.

Pancreatic cancer (PC) represents the 6th cause of cancer death. Although the aetiology of PC is not completely understood, numerous risk factors have been identified in association with this cancer, among them diet. However, little is known about the association between the Mediterranean Diet (MedDiet) and the risk of PC. For this reason, we conducted a systematic review with meta-analysis according to the PRISMA guidelines, searching on three databases (PubMed/MEDLINE, Scopus, and EMBASE). The protocol was registered in PROSPERO. Both fixed and random effect models were performed. The Effect size was reported as a hazard ratio (HR) with a 95% Confidence Interval (CI). A total of eight articles were included. The methodological quality of the included meta-analyses was high. Our results show that a higher adherence to the MedDiet is associated with a lower risk of PC [HR:0.82 (0.76-0.88) p < 0.001, based on 1,301,320 subjects]. The results were also confirmed in sensitivity and subgroups analyses (avoidance of potential overlapping effects, type of tools used to assess dietary intake and the diagnosis of PC, prevalence and incidence of PC risk, country where the studies took place, sex, and cancer site). Promoting a higher adherence to the MedDiet could be an effective approach to reduce the risk of PC.

Managing the impact of inter-method bias of prostate specific antigen assays on biopsy referral: the key to move towards precision health in prostate cancer management.

OBJECTIVES: We assessed the inter-method bias of total (tPSA) and free (fPSA) prostate-specific antigen (PSA) immunoassays to establish if tPSA-based risk thresholds for advanced prostate cancer (PCa), obtained from one method (Roche) can be converted into the corresponding concentrations assayed by other methods. Then we evaluated the impact of the bias of tPSA and fPSA on the estimation of the %f/tPSA ratio and performed a re-calibration of the proposed thresholds for the %f/tPSA ratio according to the assay used. METHODS: tPSA and fPSA were measured in 135 and 137 serum samples, respectively by Abbott Alinity i, Beckman Access Dxl, Roche Cobas e801, and Siemens Atellica IM analytical platforms. Scatterplots, Bland-Altman diagrams, Passing-Bablok (PB) were used to inspect and estimate the systematic and proportional bias between the methods. The linear equations with confidence intervals of the parameter estimates were used to transform the tPSA risk thresholds for advanced PCa into the corresponding concentrations measurable by the other analytical methods. To construct a correction coefficient for converting the %f/tPSA ratio from one method to the other, PB and non-parametric boostrapping were used. RESULTS: The inter-method bias is not constant but strictly linear allowing the conversion of PSA results obtained from Roche into the other assays, which underestimate tPSA vs. Roche. Siemens and Abbott vs. Roche and Beckman assays, being characterized by a positive and a negative proportional bias for tPSA and fPSA measurements, tend to overestimate the %f/tPSA ratio. CONCLUSIONS: There is a consistent risk to miss advanced PCa, if appropriate conversion factors are not applied.

Caregivers' Attitudes Toward COVID-19 Vaccination in Children and Adolescents With a History of SARS-CoV-2 Infection.

Background: Limited data are available on the attitudes of caregivers toward COVID-19 vaccination in children and adolescents with a history of SARS-CoV-2 infection or Long Covid symptoms. The aim of this study was to investigate the vaccine hesitancy among caregivers of children and adolescents with a documented history of SARS-CoV-2 infection and to explore the possible associations between COVID-19 manifestations and the acceptance of the vaccine. Methods: Caregivers of children or adolescents with a microbiologically confirmed diagnosis of SARS-CoV-2 infection evaluated in two University Hospitals were interviewed. Results: We were able to contact 132 caregivers and 9 declined to participate. 68 caregivers (56%) were in favor of COVID-19 vaccination for their child. In the multiple logistic regression, child's age (OR 1.17, 95%CI 1.06-1.28) and hospitalization due to COVID-19 (OR 3.25, 95%CI 1.06-9.95) were positively associated with being in favor of COVID-19 vaccination. On the contrary, the occurrence of child's Long Covid was associated with a higher likelihood of being against the vaccination (OR 0.28, 95%CI 0.10-0.80). Conclusions: This preliminary study shows that only about half of the interviewed parents of children and adolescents with a previous SARS-CoV-2 infection are willing to vaccinate them to prevent a repeated COVID-19 infection. These findings might help healthcare workers to provide tailored information to caregivers of children with a previous SARS-CoV-2 infection.

Correlation between fall risk increasing drugs (FRIDs) and fall events at a rehabilitation hospital.

Background and aim Falls and fall-related injuries are a major public health issue which needs global attention due to its clinical and socioeconomic impact. Important risk factors for falls are polypharmacy and the assumption of so-called Fall Risk Increasing Drugs (FRIDs). Aims of our study were to investigate the associations between falls and the use of medications among inpatients by conducting a retrospective case-control study in a rehabilitation hospital in Northern Italy in 2018. Methods A Conditional Logistic Regression was performed to analyze the impact that 13 types of FRIDs individually and the number of administrated FRIDs had on the risk of falling. A second regression model was obtained adjusting the case-control matching for CIRS, Morse and Barthel scores. Results We identified 148 cases and 444 controls. 3 types of FRIDs were significantly correlated (p < 0,05) with an increased risk of falling: Antipsychotics, Antidepressants, Diuretics. Antidepressants were the only type of FRID significantly correlated (p=0,008) even in the model adjusted for CIRS, Morse and Barthel scores. The unadjusted model showed that the addition of one type of FRID to therapy was significantly associated with the fall event (p<0.05). Conclusion Assumption of drugs, in particular antidepressant and polypharmacy, can play a role in hospital falling. The fall risk assessment tools available, suffer from low specificity and sensitivity and do not assess these risk factors. A holistic approach with a multidimensional evaluation of the patient through screening tools, functional assessment tools and a full medical evaluation should be pursued to improve prediction.

Side effects among healthcare workers from a large Milan university hospital after second dose of BNT162b2 mRNA COVID-19 vaccine.

BACKGROUND: In Italy, healthcare workers (HCWs) were among the first to receive COVID-19 vaccination. Aim of the present study is to evaluate frequency and severity of adverse events (AEs) following the second dose of BNT162b2 vaccine among HCWs of a large university hospital in Milan, Italy. METHODS: One month after having received the second dose of vaccine, HCWs filled-in a form about type, severity, and duration of post-vaccination local and systemic symptoms. We calculated the overall frequency of AEs and used multivariable Poisson regression models (adjusted for sex, age, BMI, smoking, allergy history, previous SARS-CoV-2 infection, anti-hypertensive therapy, and occupation) to calculate risk ratios (RR) and 95% confidence intervals (CI) of AEs according to selected variables. RESULTS: We included 3659 HCWs. Overall, 2801 (76.6%) experienced at least one local event, with pain at injection site being the most frequent (2788, 76.2%). Systemic events were reported by 2080 (56.8%) HCWs, with fatigue (52.3%), muscle pain (42.2%), headache (37.7%), joint pain (31.9%), and fever (26.2%) being the most frequent. Risks of systemic events were associated with female gender (RR=1.14, CI: 1.06-1.23), age (strong decrease with increasing age, p-trend<0.001), allergy history (RR=1.13, CI: 1.05-1.20), and current smoking (RR=0.90, CI: 0.84-0.97). HCWs with previous SARS-CoV-2 infection (even if symptomatic) were not at increased risk. CONCLUSIONS: Both local and systemic acute effects after second dose of BNT162b2 vaccine were frequently reported. However, symptoms were mostly light/mild and of short duration. Thus, our findings support the safety of COVID-19 vaccination in adults in relatively good health.

[Women's perception, preconceptions, and information preferences for the limitations of breast cancer screening and overdiagnosis: a think-aloud study on the new information materials of the Agency for Health Protection of the Metropolitan Area of Milan]. / Percezione, pregiudizi e preferenze informative delle donne milanesi sui limiti dello screening mammografico e sulla sovradiagnosi: indagine think-aloud sul nuovo materiale comunicativo dell'Agenzia di tutela della salute della Città Metropolitana di Milano.

BACKGROUND: communicating breast cancer screening (BCS) limits and overdiagnosis implies providing complete and balanced information to allow informed decision-making. OBJECTIVES: to describe women's perceptions, preconceptions, and information preferences regarding the breast cancer screening (BCS) programme paper and web information materials of the Agency for Health Protection of the Metropolitan Area of Milan (Lombardy Region, Northern Italy). DESIGN: qualitative, descriptive study. SETTING AND PARTICIPANTS: participants' voluntary recruitment took place in the registration departments of three hospitals. Participants were purposively recruited based on sociodemographic characteristics of the target population of the programme (44 women aged 40-74 years, living in the Metropolitan Area of Milan). In each material type subgroup, different health literacy levels and age classes were included, until thematic saturation was reached. MAIN OUTCOME MEASURES: thematic analysis of qualitative data collected during think-aloud interviews. RESULTS: the thematic analysis identified 5 main themes: 1. validation of the information reported in the materials, according to the interviewees' personal experiences;2. information preferences of particular subgroups of women, which led to a tailored approach for the web materials;3. negative emotions elicited while receiving information regarding BCS limits, which guided the rewriting of certain definitions; 4. disproportioned risk perception, with greater weight attributed to the risk of false negative results than the risk of overdiagnosis; 5. organizational preferences regarding the type and frequency of the provided tests and the age limits of the programme. CONCLUSIONS: in the present sample of women living in the Metropolitan Area of Milan, knowledge and comprehension of overdiagnosis are scarce. The main reasons for distrust in the BCS programme rely on the preexisting beliefs regarding the most appropriate tests and age limits. These beliefs were established from previously received information, inconsistent with that officially provided by the programme.

Screening of women with aesthetic prostheses in dedicated sessions of a population-based breast cancer screening programme.

BACKGROUND: Women with aesthetic prostheses must be included in the target population of mammography screening programmes. Breast implants are radiopaque and partially obscure the breast tissue. This can be avoided with the use of the Eklund technique, which causes an increased radiation exposure. In this study, augmented women undergoing a dedicated protocol within a population-based screening programme were compared according to selected indicators with the standard screening population. Essential dosimetric parameters and their time trend were also assessed. MATERIALS AND METHODS: The study was conducted in a screening centre in Milan in the years 2009-2016. The screening protocol for women with breast implants included a double-read mammography with the Eklund views, ultrasound and clinical breast examination. RESULTS: A total of 28,794 women were enrolled, including 588 (2%) women with breast implants and 28,206 (98%) undergoing the standard screening protocol. The invasive assessment rate was 9.0‰ for women with breast implants vs. 15‰ in the standard cohort. The surgical referral rate was 2.2% vs. 0.9%. The detection rate was similar in the two groups (4.0 and 4.5‰, respectively). There were significant differences in the average glandular dose according to the mammography equipment. The use of the Eklund views increased over time. CONCLUSIONS: Screening of augmented women according to a specific protocol in the contexts of population-based programmes is feasible. Observed differences in screening indicators relative to the standard screening population require further research. The increasing use of Eklund views probably results from quality assurance measures associated with screening programmes.

Prevalence of SARS-CoV-2 in an area of unrestricted viral circulation: Mass seroepidemiological screening in Castiglione d'Adda, Italy.

Castiglione D'Adda is one of the municipalities more precociously and severely affected by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) epidemic in Lombardy. With our study we aimed to understand the diffusion of the infection by mass serological screening. We searched for SARS-CoV-2 IgGs in the entire population on a voluntary basis using lateral flow immunochromatographic tests (RICT) on capillary blood (rapid tests). We then performed chemioluminescent serological assays (CLIA) and naso-pharyngeal swabs (NPS) in a randomized representative sample and in each subject with a positive rapid test. Factors associated with RICT IgG positivity were assessed by uni- and multivariate logistic regression models. Out of the 4143 participants, 918 (22·2%) showed RICT IgG positivity. In multivariable analysis, IgG positivity increases with age, with a significant non-linear effect (p = 0·0404). We found 22 positive NPSs out of the 1330 performed. Albeit relevant, the IgG prevalence is lower than expected and suggests that a large part of the population remains susceptible to the infection. The observed differences in prevalence might reflect a different infection susceptibility by age group. A limited persistence of active infections could be found after several weeks after the epidemic peak in the area.

Three-year analysis of repeated laboratory tests for the markers total cholesterol, ferritin, vitamin D, vitamin B12 , and folate, in a large research and teaching hospital in Italy.

RATIONALE, AIMS AND OBJECTIVES: The increasing number of diagnostic tests requests all over the world is a problem that can partially be explained by inappropriate testing. Impact on the total costs of health systems becomes relevant when tests are performed in a large amount. In this paper, retesting of total cholesterol, ferritin, vitamin B12 , vitamin D, and folate is assessed. METHODS: The Quality Unit of Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico di Milano (Fondazione) decided to perform a first assessment of the appropriate use of the laboratory tests cholesterol, ferritin, vitamin B12 , vitamin D, and folate focusing on the retesting interval for the same patient in the time period January 1, 2012, to December 31, 2014, in every care setting. The minimum retesting intervals were chosen following the ACB recommendations. The Fondazione is a research and teaching hospital with 3 emergency units (adult, pediatric, and obstetric), kidney, liver, lung, cornea, and bone marrow transplant centers and a medical school. Record linkage of laboratory records selected for the time interval January 1, 2012, to December 31, 2014, was applied using tax code. For each marker, the distribution of retesting intervals was evaluated for every year and the total period. With the same record linkage variable, requests on inpatients were identified from hospital discharge records. A cost analysis of inappropriate retesting was performed for every test. RESULTS: We examined 466 035 requests for 113 019 patients. Proportions of tests judged potentially inappropriate varied between 8.1% for 1,25-dihydroxy vitamin D and 37.1% for total cholesterol. The rates of inappropriate tests from year to year never showed significant decrease, and the maximum increase corresponded to an odds ratio of 1.85 (95% CI, 1.36-2.51) for 1,25-dihydroxy vitamin D from 2012 to 2013. Calculated loss of money was approximately €500 000 in the 3 years. CONCLUSIONS: Inappropriate requests represent a waste of time and money resources. Our analysis highlighted economically unacceptable rates of inappropriate retesting, with no evidence of decreasing trend. Actions to raise awareness in clinicians or automated electronic solutions are necessary to limit unnecessary test repetitions.

Knowledge, attitudes, and smoking behaviours among physicians specializing in public health: a multicentre study.

BACKGROUND: Healthcare professionals have an important role to play both as advisers-influencing smoking cessation-and as role models. However, many of them continue to smoke. The aims of this study were to examine smoking prevalence, knowledge, attitudes, and behaviours among four cohorts physicians specializing in public health, according to the Global Health Profession Students Survey (GHPSS) approach. MATERIALS AND METHODS: A multicentre cross-sectional study was carried out in 24 Italian schools of public health. The survey was conducted between January and April 2012 and it was carried out a census of students in the selected schools for each years of course (from first to fourth year of attendance), therefore among four cohorts of physicians specializing in Public Health (for a total of n. 459 medical doctors). The GHPSS questionnaires were self-administered via a special website which is created ad hoc for the survey. Logistic regression model was used to identify possible associations with tobacco smoking status. Hosmer-Lemeshow test was performed. The level of significance was P ≤ 0.05. RESULTS: A total of 388 answered the questionnaire on the website (85%), of which 81 (20.9%) declared to be smokers, 309 (79.6%) considered health professionals as behavioural models for patients, and 375 (96.6%) affirmed that health professionals have a role in giving advice or information about smoking cessation. Although 388 (89.7%) heard about smoking related issues during undergraduate courses, only 17% received specific smoking cessation training during specialization. CONCLUSIONS: The present study highlights the importance of focusing attention on smoking cessation training, given the high prevalence of smokers among physicians specializing in public health, their key role both as advisers and behavioural models, and the limited tobacco training offered in public health schools.

Should I pay for your risky behaviours? Evidence from London.

We investigate the extent to which respondents from a general population sample in London (July-August 2011) agree or disagree with the NHS covering the healthcare costs related to five risky health behaviours: overeating, unhealthy diet, sedentary life, excess of alcohol, and smoking. For each behaviour, we also directly explore the main factors associated with the likelihood to agree or disagree. Half of the respondents (N=146) manifest agreement with the idea. Wider agreement exists for covering the costs associated smoking, heavy drinking, and sedentary lives than with overeating, or poor diets. With the exception of alcohol drinking and sedentary life, there is an almost one-to-one relationship between the agreement that the NHS should pay the healthcare costs associated with a specific behaviour, and the respondents' actual engagement in that behaviour. Those at higher risk of depending on publicly funded healthcare, are more likely to agree.

Feasibility study for the introduction of a new treatment method for benign thyroid nodules in a teaching and research hospital.

RATIONALE, AIMS AND OBJECTIVES: Numerous scientific publications have confirmed that percutaneous laser thermal ablation (LTA) represents a possible therapeutic option in selected patients with benign thyroid nodules. A study was carried out to evaluate the feasibility of adopting the LTA technique to treat benign thyroid nodules in a teaching and research hospital in northern Italy. METHODS: A cost analysis from a company's perspective determined the impact of adoption of the new technique on the overall Hospital budget, considering currently available equipment, infrastructure and personnel, equipment costs and treatment tariffs. RESULTS: The cost analysis shows that, strictly from an economic point of view, any provision of the LTA technique will result as a loss on the Hospital's balance sheet. However, it does not estimate the extent of the impact on the overall budget because it did not evaluate the savings that such a technique would make with respect to alternative therapeutic treatments. Therefore, the Hospital policy management decided to extend the current agreement with a private authorized health care structure that already carries out LTA. Also, although difficult to express in economic terms, this new technique would undoubtedly raise the profile and enhance the reputation of the Hospital. CONCLUSIONS: Using the new technique in these patients could cut costs for the entire regional health care system, widen the experience of the Hospital's endocrinology team and offer the potential for the procedure also to be provided by operators on a freelance basis within the Hospital.

Payment for performance (P4P): any future in Italy?

BACKGROUND: Pay for Performance (P4P) programs, based on provision of financial incentives for service quality, have been widely adopted to enhance quality of care and to promote a more efficient use of health care resources whilst improving patient outcomes. In Italy, as in other countries, the growing concern over the quality of health services provided and the scarcity of resources would make P4P programs a useful means of improving their performance. The aim of this paper is to evaluate whether it is possible to implement P4P programs in the Lombardy Region, in Italy, based on the existing data set. METHODS: Thirteen quality measures were identified regarding four clinical conditions (acute myocardial infarction (AMI), heart failure (HF), ischemic stroke and hip and knee replacement) on the basis of an international literature review. Data was collected using the database of three institutions, which included hospital discharge records (Scheda di Dimissione ospedaliera-SDO-) and letters of discharge. The study population was identified using both the Principal ICD-9-CM diagnosis codes and the discharge date. A Statistical Analysis System (SAS) program was used for the text analysis. RESULTS: It was possible to calculate almost all the parameters pertaining to the three hospitals as all the data required was available with the exception of inpatient mortality in two hospitals and smoking cessation advice/counseling in one hospital. CONCLUSIONS: On the ground of this analysis, we believe that it is possible to implement a P4P program in the Lombardy Region. However, for this program to be initiated, all necessary data must be available in electronic format and uniformly collected. Moreover, several other factors must be assessed: which clinical conditions should be included, the threshold for each quality parameter, the amount of financial incentives offered and how they will be provided.
