Six years of activity of the Italian vaccine portal "VaccinarSì": a web traffic evaluation using Google Analytics.

BACKGROUND: Despite the scientific consensus about vaccines safety and effectiveness, there is still a discrepancy between scientific evidence and perception by the general population. The "VaccinarSì" portal was created in 2013 by Italian specialists in Public Health to provide evidence-based information regarding vaccination. STUDY DESIGN: The purpose of this study was to analyse the web traffic on "VaccinarSì" platform during a six-year period (May 8, 2013-May 8, 2019). Moreover, we compared the first six-month with the last six-month period of the website activity, to identify potential areas of improvements. METHODS: This is a descriptive study using Google Analytics data. We collected data regarding the following: total number of sessions to the portal, total number of pages viewed, total number of users and the number of new visitors, geographical locations and demography of users as well as user access mode (type of device used and way of access). We also collected some data that were informative about the possibility to infer the level of visitors' engagement with the portal, such as thee number of returning users, bounce rate, number of pages visited per session and mean session duration. RESULTS: Throughout the relevant period, the portal has consistently increased its popularity, with a remarkable increment of monthly connections (ending up to more than 80,000/month) from all over Italy. Visitors were mainly female (71.1%), aged between 25 and 44 years (64.7%). Healthcare professionals were responsible for a considerable proportion of accesses (50.6%). The mobile has become the dominant device used to access the portal, accounting for 77.8% of total connection in the last six months. Similarly, in the last period, organic search accounted for 92% of all connections. Measles and MPR vaccine, as well as chickenpox and hexavalent vaccine, have remained the most appealing topics of interest among visitors over the years. The page that attracted more visitors over the six years was "real risks and benefits of vaccination", accounting for 5.67% of total sessions with a high mean duration spent of 05:08 minutes. CONCLUSION: During the six years of activity, overall, the level of users' engagement with the portal has dropped with an increased bounce rate and a lower average number of pages visited per session and a lower mean duration of each connection. The lowest engagement involved connections accessed through mobile devices. Results helped "Vaccinarsi" developers to speculate about future strategies to further increase the platform popularity and optimize visitors' engagement.

Cysteamine as a novel disease-modifying compound for Parkinson's disease: Over a decade of research supporting a clinical trial.

To date, medical and surgical interventions offered to patients with Parkinson's disease (PD) serve only to manage clinical symptoms; they have not shown the capacity to halt nor reverse degenerative processes. There is therefore an urgent need to identify and/or develop therapeutic strategies that will demonstrate 'disease modifying' capacities. The molecule cystamine, and its reduced form cysteamine, act via a number of pathways determined to be critical to the pathogenesis of PD. In particular, cystamine is capable of crossing the blood-brain barrier, and both agents (cystamine and cysteamine) can promote the secretion of neurotrophic factors, inhibit oxidative stress, reduce inflammatory responses and importantly, have already been trialed in humans for a number of other clinical indications. In the last decade, our laboratory has accumulated compelling evidence that both cystamine and cysteamine can halt, and even reverse, ongoing neurodegenerative processes in a number of different models of PD, and as such, should now be taken forward to clinical trials in PD.

[Improving vaccination social marketing by monitoring the web]. / Migliorare il marketing sociale in tema di vaccinazioni "presidiando" il Web.

Immunisation is one of the most important and cost- effective interventions in Public Health because of their significant positive impact on population health.However, since Jenner's discovery there always been a lively debate between supporters and opponents of vaccination; Today the antivaccination movement spreads its message mostly on the web, disseminating inaccurate data through blogs and forums, increasing vaccine rejection.In this context, the Società Italiana di Igiene (SItI) created a web project in order to fight the misinformation on the web regarding vaccinations, through a series of information tools, including scientific articles, educational information, video and multimedia presentations The web portal (http://www.vaccinarsi.org) was published in May 2013 and now is already available over one hundred web pages related to vaccinations Recently a Forum, a periodic newsletter and a Twitter page have been created. There has been an average of 10,000 hits per month. Currently our users are mostly healthcare professionals. The visibility of the site is very good and it currently ranks first in the Google's search engine, taping the word "vaccinarsi" The results of the first four months of activity are extremely encouraging and show the importance of this project; furthermore the application for quality certification by independent international Organizations has been submitted.

Molecular analysis of Klebsiella pneumoniae strains isolated in pediatric wards by ribotyping, pulsed field gel electrophoresis and antimicrobial susceptibilities.

The purpose of this study was to investigate the usefulness of different molecular typing techniques in the surveillance and control of the spread of extended-spectrum-beta-lactamase-(ESBL) producing Klebsiella pneumoniae in the pediatric department of the "Agostino Gemelli" hospital of the Catholic University in Rome, over a period of nine months. The strains were characterized by ribotyping using HindIII as restriction enzyme and pulsed field gel electrophoresis (PFGE) using XbaI as endonuclease. Sixty six K. pneumoniae clinical strains were isolated during this period, the first 32 were isolated in the summer of 1998. Among these first isolates, ribotyping generated 26 different patterns whereas PFGE produced 16 patterns. The remaining 34 strains were isolated during January and April 1999 and all of them were ESBL producers. Ribotyping clustered the strains into 6 patterns whereas PFGE generated only 3 patterns. PCR revealed the presence in 10 isolates of both bla(TEM) and bla(SHV) genes and 24 strains carried only the bla(SHV) gene. In our experience ribotyping revealed a higher power of differentiation with respect to PFGE and was of great help in the surveillance of the infection.
