Influenza vaccination coverage among medical residents: An Italian multicenter survey

2014

Although influenza vaccination is recognized to be safe and effective, recent studies have confirmed that immunization coverage among health care workers remain generally low, especially among medical residents (MRs). Aim of the present multicenter study was to investigate attitudes and determinants associated with acceptance of influenza vaccination among Italian MRs. A survey was performed in 2012 on MRs attending post-graduate schools of 18 Italian Universities. Each participant was interviewed via an anonymous, self-administered, web-based questionnaire including questions on attitudes regarding influenza vaccination. A total of 2506 MRs were recruited in the survey and 299 (11.9%) of t…

Pandemic influenza A (H1N1) infection in pregnant and nonpregnant women in Spain (2009-2010)

2014

The present study aimed to compare the main features of infection with pandemic influenza A virus in pregnant and nonpregnant women admitted to hospitals in Spain during the first waves of the 2009-2010 influenza pandemic. This was a prospective (November 2009 to June 2010), multicenter observational study. All cases were women of reproductive age who had not been vaccinated against seasonal or pandemic influenza A. Influenza infection was confirmed by reverse transcription-polymerase chain reaction (RT-PCR). The sociodemographic and clinical data of all cases were reviewed. A total of 219 inpatients, including 49 pregnant women and 170 nonpregnant women, were enrolled in the study upon adm…

Thromboembolic events in patients with influenza. A scoping review.

2022

Introduction: Influenza is an acute respiratory infection that usually causes a short-term and self-limiting illness. However, in high-risk populations, this can lead to several complications, with an increase in mortality. Aside from the well-known extrapulmonary complications, several studies have investigated the relationship between influenza and acute cardio and cerebrovascular events. Reviews of the thromboembolic complications associated with influenza are lacking. Objectives: the study aims to conduct a scoping review to analyze the epidemiological and clinical characteristics of patients suffering from influenza and thromboembolic complications. Materials and methods: A computerize…

Noninvasive respiratory support in acute hypoxemic respiratory failure associated with COVID-19 and other viral infections

2020

ABSTRACTIntroductionNoninvasive respiratory support (NRS) such as noninvasive ventilation (NIV) and high flow nasal therapy (HFNT) have been used in the treatment of acute hypoxemic respiratory failure (AHRF) related to the coronavirus disease (COVID-19) and other viral infections. However, there is a lack of consensus in favor of or against NRS use due to the risks of worsening hypoxemia, intubation delay, and aerosols environmental contamination associated with the use of these tools. We aimed to summarize the evidence on the use of NRS in adult patients with COVID-19 and other viral pneumonia (i.e. H1N1, SARS, MERS) and AHRF. We also searched for studies evaluating the risk of aerosoliza…

Second European evidence-based consensus on the prevention, diagnosis and management of opportunistic infections in inflammatory bowel disease

2014

The treatment of inflammatory bowel disease (IBD) has been revolutionised over the past decade by the increasing use of immunomodulators, mainly azathioprine (AZA)/6-mercaptopurine (6-MP) and methotrexate (MTX), together with the advent of biological therapy. Immunomodulators are being used more often and earlier in the course of the disease.1 The introduction of biologic agents, especially inhibitors of the key proinflammatory cytokine, tumor necrosis factor alpha (TNF-α) initiated a new therapeutic era, whose use has grown continuously since their introduction in 1998.2 With such immunomodulation, the potential for opportunistic infection is a key safety concern for patients with IBD. Opp…

Determinants of seasonal influenza vaccination in pregnant women in Valencia, Spain

2016

Background: In most countries the coverage of seasonal influenza vaccination in pregnant women is low. We investigated the acceptance, reasons for rejection and professional involvement related to vaccine information in pregnant women in Valencia, Spain. Methods: Observational retrospective study in 200 pregnant women, 100 vaccinated and 100 unvaccinated, were interviewed during the 2014/2015 vaccination campaign. Electronic medical records, immunization registry and telephone interviews were used to determine reasons for vaccination and immunization rejection. Results: 40.5% of pregnant women in the health department were vaccinated. The midwife was identified as source of information for …

TECNICHE OTTICHE PER IL MONITORAGGIO DEI CORSI D’ACQUA: UNA PROCEDURA AUTOMATICA PER L’INDIVIDUAZIONE DELLA MIGLORE SEQUENZA VIDEO DA PROCESSARE CON …

Misurare con accuratezza le portate di un corso d’acqua è uno dei principali obiettivi dell’idrometria tecnica (Eltner et al., 2020) e rappresenta da decenni una vera e propria sfida per la comunità scientifica. Le osservazioni di deflusso nei corsi d’acqua sono di fondamentale importanza per qualsiasi applicazione idrologica e idraulica (Pizarro et al., 2020) e consentono di comprendere al meglio le dinamiche di processi complessi, come ad esempio le piene lampo (Perks et al., 2016). La portata è una grandezza fisica la cui stima è caratterizzata da considerevole incertezza. Gli approcci tradizionali prevedono una stima indiretta della grandezza, attraverso un metodo velocità-area, che con…

Ultradeep Sequencing Analysis of Population Dynamics of Virus Escape Mutants in RNAi-Mediated Resistant Plants

2012

Plant artificial micro-RNAs (amiRs) have been engineered to target viral genomes and induce their degradation. However, the exceptional evolutionary plasticity of RNA viruses threatens the durability of the resistance conferred by these amiRs. It has recently been shown that viral populations not experiencing strong selective pressure from an antiviral amiR may already contain enough genetic variability in the target sequence to escape plant resistance in an almost deterministic manner. Furthermore, it has also been shown that viral populations exposed to subinhibitory concentrations of the antiviral amiR speed up this process. In this article, we have characterized the molecular evolutiona…

Attitudes, behaviours and perceptions of Italian General Practitioner trainees towards influenza vaccination in Western Sicily (Italy)

2012

Background: General practitioners (GPs) have to be considered as key figures of health promotion among health care workers since they are strongly asked to recommend influenza vaccination to their patients and perform on them. Despite this consideration, GPs have influenza vaccination rates that are significantly below the 75% coverage proposed by International Public Health guidelines. In order to increase future coverage of influenza vaccination within GPs, and through them within the population, the aim of this study was to assess determinants associated with influenza vaccine uptake among GP trainees. Methods: A survey was carried out on GP trainees attending the training course in Comm…
