Do Degree Programs Affect Health Profession Students' Attitudes and Opinions Toward Vaccinations? An Italian Multicenter Study

2019

Abstract Background Healthcare workers' attitudes toward vaccination have been widely described in the literature, but a restricted amount of studies assessed healthcare students' knowledge, attitudes, and opinions on this issue. This study aimed to estimate the influence of a degree course on knowledge and immunization behavior among healthcare students and to compare medical students with students from other health profession degree programs to identify possible differences. Methods A multicenter, cross-sectional study was performed in 2018 in 14 Italian Universities (3,131 students were interviewed). A validated questionnaire was used to assess knowledge, attitudes, and opinions toward v…

Fulminant bilateral Haemophilus influenzae keratitis in a patient with hypovitaminosis A treated with contaminated autologous serum

2011

We report on a patient with hypovitaminosis A treated with autologous serum (AS) who had bilateral infectious ulcers positive for Haemophilus influenzae. The patient suffered a perforation of his right eye and total healing of his left eye with a residual leukoma. In cases of severe malnutrition, serum levels of vitamins and bacteriostatic and growth factors are reduced, so AS would not only be ineffective but also increase the risk of secondary corneal infection. The prophylactic use of a topical antibiotic would be useful in treatment with AS, especially in patients who do not use and adequately store the eye drops, as in our patient.

Vaccination Against Influenza: Attitude of Health Care Personnel in a Multidisciplinary Hospital in Latvia

2019

Abstract Health care personnel (HCP) are at high risk of acquiring influenza due to exposure to patients. However, vaccination in HCP is lower than 40% for most European countries. The aim of this study was to determine the attitude towards influenza vaccination and possible reasons for this attitude in HCP. A cross-sectional study was performed in a multidisciplinary hospital of Latvia. The sample (n = 1099) included doctors (239), nurses (418), care services (236), administrative staff (108), and technical support staff (98). Five questions addressed vaccination of planned patients and HCP, knowledge of etiological anti-influenza drugs, and their storage at the hospital for immediate use.…

The relevance for Public Health of the mid-term and interim analyses of seasonal influenza vaccination effectiveness

2019

Worldwide, influenza is commonly recognized as a respiratory virus that causes a high number of deaths every year, especially among elderly adults and people with chronic illnesses. In order to reduce morbidity and mortality, many countries have implemented, in the last decades, universal influenza vaccination programs with special attention on groups at increased risk of developing the disease, such as pregnant women, children aged 6–59 months, elderly adults and individuals with specific chronic medical conditions. In real-world conditions, observational (nonrandomized) studies on vaccine effectiveness (VE) could measure,the risk reduction of contracting a disease and are considered the g…

Rac1 and PAK1 are upstream of IKK-ε and TBK-1 in the viral activation of interferon regulatory factor-3

2004

The anti-viral type I interferon (IFN) response is initiated by the immediate induction of IFN beta, which is mainly controlled by the IFN-regulatory factor-3 (IRF-3). The signaling pathways mediating viral IRF-3 activation are only poorly defined. We show that the Rho GTPase Rac1 is activated upon virus infection and controls IRF-3 phosphorylation and activity. Inhibition of Rac1 leads to reduced IFN beta promoter activity and to enhanced virus production. As a downstream mediator of Rac signaling towards IRF-3, we have identified the kinase p21-activated kinase (PAK1). Furthermore, both Rac1 and PAK1 regulate the recently described IRF-3 activators, I kappa B kinase- and TANK-binding kina…

Immunogenicity and safety of a quadrivalent high-dose inactivated influenza vaccine compared with a standard-dose quadrivalent influenza vaccine in h…

2021

A quadrivalent high-dose inactivated influenza vaccine (IIV4-HD) is licensed for adults ≥65 y of age based on immunogenicity and efficacy studies. However, IIV4-HD has not been evaluated in adults aged 60–64 y. This study compared immunogenicity and safety of IIV4-HD with a standard-dose quadrivalent influenza vaccine (IIV4-SD) in adults aged ≥60 y. This Phase III, randomized, modified double-blind, active-controlled study enrolled 1,528 participants aged ≥60 y, randomized 1:1 to a single injection of IIV4-HD or IIV4-SD. Hemagglutination inhibition (HAI) geometric mean titers (GMTs) were measured at baseline and D 28 and seroconversion assessed. Safety was described for 180 d after vaccinat…

Bayesian temporal and spatio-temporal Markov switching models for the detection of influenza outbreaks

2017

Influenza is a disease which affects millions of people every year and causes hundreds of thousends of deads every year. This disease causes substantial direct and indirect costs every year. The influenza epidemic have a particular behavior which shapes the statistical methods for their detection. Seasonal epidemics happen virtually every year in the temperate parts of the globe during the cold months and extend throughout whole regions, countries and even continents. Besides the seasonal epidemics, some nonseasonal epidemics can be observed at unexpected times, usually caused by strains which jump the barrier between animals and humans, as happened with the well known Swine Flu epidemic, w…

2014

Introduzione: Nel corso della stagione influenzale, gli Operatori Sanitari (OS) rappresentano una delle categorie lavorative maggiormente investite dalla responsabilità di limitare la diffusione della patologia influenzale tra i pazienti ospedalizzati e contemporaneamente di proteggere se stessi garantendo la continuità dell'assistenza sanitaria nei periodi di maggiore assenteismo lavorativo e sovraccarico delle attività assistenziali (picco influenzale stagionale). La vaccinazione antinfluenzale, ormai riconosciuta sicura ed efficace, rappresenta ancora oggi una argomento di dibattito tra gli OS, nonostante le raccomandazioni dei Center for Disease Control and Prevention Statunitense ed Eu…
