Silvia Coretti,1 Federica Romano,1 Valentina Orlando,2 Paola Codella,1 Sabrina Prete,1 Eugenio Di Brino,1 Matteo Ruggeri1 1Post-Graduate School of Economics and Management (ALTEMS), Università Cattolica del Sacro Cuore, Rome, Italy; 2Center of Pharmacoeconomics (CIRFF), Department of Pharmacy, Federico II University, Naples, Italy Background: Hepatitis C is a liver infection caused by hepatitis C virus. Its main complications are cirrhosis and liver cancer. According to the World Health Organization (WHO), more than 185 million people worldwide are infected with hepatitis C virus and, of these, 350,000 die every year. Due to the high disease prevalence and the existence of effective (and expensive) medical treatments able to dramatically change the prognosis, early detection programs can potentially prevent the development of serious chronic conditions, improve health, and save resources. Objective: To summarize the available evidence on the cost-effectiveness of screening programs for hepatitis C. Methods: A literature search was performed on PubMed and Scopus search engines. Trip database was queried to identify reports produced by the major Health Technology Assessment (HTA) agencies. Three reviewers dealt with study selection and data extraction blindly. Results: Ten papers eventually met the inclusion criteria. In studies focusing on asymptomatic cohorts of individuals at general risk the cost/quality adjusted life year of screening programs ranged between US 50,000/quality adjusted life year gained, while in those focusing on specific risk factors the incremental cost-effectiveness ratio ranged between 128,424/quality adjusted life year gained. Age of the target population and disease prevalence were the main cost-effectiveness drivers. Conclusion: Our results suggest that, especially in the long run, screening programs represent a cost-effective strategy for the management of hepatitis C.

Economic assessment of an anti-HCV screening program in Italy
The progression of hepatitis C virus (HCV) disease usually occurs over a 10-year period. HCV-related complications as well as the highly debilitating effects on patients represent a significant item of expenditure for the National Health Service. Early detection of HCV infection is an excellent opportunity to improve patients' quality of life and to rationalize resource allocation
Economic Analysis and Budget Impact of Tenofovir and Entecavir in the First-Line Treatment of Hepatitis B Virus in Italy
Background: Chronic hepatitis B is a common, progressive disease, particularly when viral replication is detected. Oral antivirals can suppress viral replication and prevent or delay the development of cirrhosis and liver-related complications. The treatments of chronic hepatitis B cannot totally cure the disease but can prevent its progression to hepatocellular carcinoma, decreasing the levels of both morbidity and mortality. To date, there are several therapies indicated by the international guidelines as first-line treatments for the management of hepatitis B; two of the most effective are those based on either tenofovir or entecavir. Objective: The aim of this study is to evaluate the cost-effectiveness of tenofovir and entecavir in the treatment of naïve patients with chronic hepatitis B. The two treatments are compared with the “no treatment” and to one another. Methods: The cost-effectiveness analysis was conducted using a Markov model; patients entered one of the following health states: chronic hepatitis, cirrhosis (compensated or decompensated), hepatocellular carcinoma, liver transplantation or death. The analysis was carried out from the perspective of the Italian National Health Service by considering a life-time horizon with cycles lasting 1 year and with costs and QALYs (quality-adjusted life years) discounted at a rate of 3.5%. The results of the model were analysed in terms of incremental cost-effectiveness ratio (ICER). Results: ICERs for tenofovir and entecavir emerging from the comparison versus “no treatment” were equal to €10,274.73 and €16,300.44 per QALY gained, respectively, on the life-time horizon. Tenofovir was dominant in the direct comparison with entecavir, indicating more QALYs and a lower consumption of resources. The Monte Carlo simulation demonstrated that in 97% (tenofovir) and in 85% (entecavir) of the scenarios performed, the cost per QALY fell below the threshold of €30,000/QALY. The budget impact analysis showed savings for tenofovir amounting to 33% compared to entecavir in the first year on treatment and to 31% in following years. Conclusions: Entecavir and tenofovir are recommended for the treatment of patients with chronic Hepatitis B in the Italian Health System. In particular, tenofovir appeared to be the more cost-effective drug for the management of chronic hepatitis B virus (HBV) infections. These results could help decision makers and clinicians to address their decision when choosing a first-line treatment for the management of people affected by chronic HBV
Candida Bloodstream Infections in Italy: Changing Epidemiology during 16 Years of Surveillance.
Although considerable progress has been made in the management of patients with invasive fungal infections, Candida bloodstream infections are still widespread in hospital settings. Incidence rates vary geographically, often because of different patient populations. The aim of the present study was to describe the epidemiology of candidemia, to analyze the trend of species distribution, and to measure the in vitro susceptibility to antifungal drugs in a university Italian hospital from 1998 to 2013. The antifungal susceptibility for all Candida isolates was evaluated by broth microdilution assay (CLSI M27-A3 document). Of 394 episodes of candidemia, the average incidence was 3.06/10 000 admissions. C. albicans and non-albicans Candida species caused 44.2% and 55.8% of the episodes, respectively. C. parapsilosis (62.2%) was the most common non-albicans. C. albicans predominated in almost all departments whereas C. parapsilosis was found in adult and paediatric oncohaematology units (34.8% and 77.6%, resp.). Overall, mortality occurred in 111 (28.2%) patients. Death occurred most often in intensive care units (47.1%) and specialist surgeries (43.7%). Most of the isolates were susceptible to antifungal drugs, but there was an upward trend for azole (P<0.05). In conclusion, this study emphasizes the importance of monitoring local epidemiologic data and the diversity of patient groups affected
New professional roles and patient satisfaction: evidence from a European survey along three clinical pathways
This paper reports the results of an empirical analysis exploring the impact of new professions (eg a physician associate) and new professional roles on patient experiences of and satisfaction with care. A sub set of data from a patient survey conducted as part of the MUNROS programme of work was used. The overall survey aim was to describe and quantify the use of new professionals and new roles for established health care professionals other than medical doctors, in primary and secondary care sectors in three care pathways in nine European countries Ordered logit models were used to investigate the association between: (1) patient satisfaction with the last visit; (2) with their care provider; (3) with the information provided and a set of covariates explaining the involvement of new professional roles in three clinical pathways: type 2 diabetes, heart disease and breast cancer. For patients with breast cancer, high levels of satisfaction are associated with the involvement of new professions/professional roles in the provision of conditions specific education and monitoring. For patients with heart disease, the involvement of new professions/professional roles is likely to have a negative impact on satisfaction. For patients with Type 2 diabetes results are ambivalent. Patients belonging to countries experiencing innovative models of healthcare delivery and with high levels of involvement of new professions/professional roles are generally more satisfied. In conclusion, the introduction of new professions does not affect patient satisfaction negatively, therefore introducing new health professional roles is a pursuable strategy from a patient satisfaction perspective, at least for breast cancer and type 2 diabetes
Insect-based diet, a promising nutritional source, modulates gut microbiota composition and SCFAs production in laying hens. [Borrelli L. and Coretti L. co-first authors]
Insects could be potential nutritional sources both for humans and animals. Among these, Hermetia illucens, with good amount of chitin and proteins, represents a suitable diet replacement for laying hens. Little is known about insect diet effects on the microbial ecology of the gastrointestinal tract and bacterial metabolites production. In this study we investigated the effect of H. illucens larvae meal administration on cecal microbiota and short chain fatty acids (SCFAs) production in laying hens. 16S rDNA sequencing showed strong differences between cecal microbiota of soybean (SD) and insect diet (ID) groups both in type and relative abundance (unweighted and weighted beta diversity) of microbial species. In particular, Bacteroides plebeius, Elusimicrobium minutum, Alkaliphilus transvaalensis, Christensenella minuta, Vallitalea guaymasensis and Flavonifractor plautii represented the principal contributors of changes in gut microbiota composition of ID group (FDR p-values < 0.05). Of these, F. plautii, C. minuta and A. transvaalensis have the potential to degrade the chitin's insect meal and correlated with the observed high levels of gut SCFAs produced in ID group. These microorganisms may thus connect the chitin degradation with high SCFAs production. Our results suggest H. illucens as a potential prebiotic by well feeding gut microbiota
