Background And Objective: During 2020, the only instruments for fighting against the pandemic peaks were lockdowns, physical distancing, closure of schools and non-essential businesses, and travel restrictions. The new vaccination strategy adopted in Italy in 2021 represented a new perspective for policymakers.
Objective: The aim of this study was to estimate the effects of the national immunisation strategy for coronavirus disease 2019 (COVID-19) in Italy on the national healthcare system.
Methods: An epidemiological scenario analysis was developed in order to simulate the impact of the COVID-19 pandemic on the Italian national healthcare system in 2021. Hospitalisations, intensive care unit (ICU) admissions and death rates were modelled based on 2020 data. Costs were estimated using hospital admissions from the Policlinico of Tor Vergata Hospital in Rome. Two scenarios were tested, one with vaccination and the second without.
Results: The roll-out of vaccinations to protect against COVID-19 was estimated to prevent 52,115 deaths in 2021, 45.2% less than what was expected in the absence of immunisation. Based on the assumptions underlying the two epidemiological scenarios, our model predicted an overall reduction of 2.4 million hospital admissions and 259,000 ICU admissions (74.9% and 71.3% less, respectively, than the world without vaccinations between June and December 2021). Overall, in Italy, the model estimated over €3.0 billion costs of hospitalisations due to COVID-19 in 2020. In 2021, vaccines prevented around 36% of the overall costs.
Conclusions: This is the first study highlighting the effect of vaccines on the Italian healthcare system in terms of avoided cases, hospitalisations and costs. Our results have the potential to inform policymakers and the general population on the benefits of vaccinations.

Perspectives and experiences regarding pre-exposure prophylaxis (PrEP) in a community sample of Veterans with unhealthy alcohol use: overall and across sexual orientation and gender identity.

Background: Unhealthy alcohol use is an independent, modifiable risk factor for HIV, but limited research addresses alcohol use and HIV prevention synergistically. Groups that experience chronic stigma, discrimination, and/or other marginalization, such as sexual and gender minoritized groups, may have enhanced HIV risk related to unhealthy alcohol use. We described awareness of and experiences with pre-exposure prophylaxis (PrEP) among a community sample of Veterans reporting unhealthy alcohol use (relative to those without), overall and across self-reported sexual orientation and gender identity.

Background: Because cirrhosis is often unrecognized, we aimed to develop a stepwise screening algorithm for cirrhosis in the Veterans Health Administration (VHA) and assess this approach's feasibility and acceptability.
Methods: VHA hepatology clinicians ("champions") were invited to participate in a pilot program from June 2020 to October 2022. The VHA Corporate Data Warehouse was queried to identify Veterans with possible undiagnosed cirrhosis using Fibrosis-4 (FIB-4) ≥ 3.
Does drug dispensing influence patients' medication knowledge and medication adherence? A systematic review and meta-analysis.

Laboratory of Innovation for Healthcare (Linc), Postgraduate Program in Pharmaceutical Sciences, Federal University of Espírito Santo, Vitória, ES, Brazil.
Background: Inadequate medication knowledge and medication nonadherence by patients are considered an issue in healthcare, as they can lead to negative outcomes, such as therapeutic failures and hospitalization. Even though drug dispensing, which has pharmacist counseling as a core element, is a service traditionally performed by pharmacists, there is still no evidence about the influence of this service on these health outcomes.
Objective: To evaluate the influence of drug dispensing on patients' medication knowledge and medication adherence.
To what extent are digital health interventions targeting HIV care cascade among mobile populations feasible, acceptable, and effective? A mixed methods systematic review protocol.

Introduction: Human mobility is associated with an increased risk of HIV acquisition and disengagement from HIV care, leading to poorer health outcomes among highly mobile individuals compared to less mobile individuals. Mobile individuals, broadly defined as those who temporally, seasonally, or permanently move from one place to another for voluntary or involuntary reasons, face many challenges in accessing HIV care services. These challenges include logistical difficulties, interruptions in HIV care continuity, and limited access to services across different locations, which together hinder timely testing, treatment initiation, and viral suppression.

Introduction: Several adverse drug reactions (ADRs) go unreported within a healthcare setting despite the risks they cause. We therefore decided to conduct this study in order to recognize the obstacles that hinder the healthcare professionals (HCPs) in a tertiary care hospital in Kattankulathur, Tamil Nadu from reporting ADRs and what strategies ought to be implemented.
Methods: We carried out a cross-sectional study among the HCPs such as doctors, pharmacists and nurses within our institution.
