    Abstract Introduction: More than two years after SARS-CoV-2 emerged in Wuhan, China, COVID-19 has become one of the most severe pandemics in modern human history. Prior to the widespread availability of specific vaccines in 2021, public opinion surveys indicated significant vaccine hesitancy in 26 European countries.
    Materials and methods: Epidemiological data on COVID-19 morbidity and mortality for 26 European countries were collected in November 2021 and compared with the proportions of people willing to receive the SARS-CoV-2 vaccine according to public opinion surveys analysed in 2020. Correlations between various variables were calculated using the Pearson correlation test and visualized with the R programming language.
    Results: Paired Student's
    Conclusion: Encouraging widespread immunization through vaccination was crucial for rapidly improving the epidemiological situation in Europe.

  5. Article ; Online: Using Twitter for sentiment analysis towards AstraZeneca/Oxford, Pfizer/BioNTech and Moderna COVID-19 vaccines.

    Marcec, Robert / Likic, Robert

    2021  Volume 98, Issue 1161, Page(s) 544–550

    Abstract Introduction: A worldwide vaccination campaign is underway to bring an end to the SARS-CoV-2 pandemic; however, its success relies heavily on the actual willingness of individuals to get vaccinated. Social media platforms such as Twitter may prove to be a valuable source of information on the attitudes and sentiment towards SARS-CoV-2 vaccination that can be tracked almost instantaneously.
    Materials and methods: The Twitter academic Application Programming Interface was used to retrieve all English-language tweets mentioning AstraZeneca/Oxford, Pfizer/BioNTech and Moderna vaccines in 4 months from 1 December 2020 to 31 March 2021. Sentiment analysis was performed using the AFINN lexicon to calculate the daily average sentiment of tweets which was evaluated longitudinally and comparatively for each vaccine throughout the 4 months.
    Results: A total of 701 891 tweets have been retrieved and included in the daily sentiment analysis. The sentiment regarding Pfizer and Moderna vaccines appeared positive and stable throughout the 4 months, with no significant differences in sentiment between the months. In contrast, the sentiment regarding the AstraZeneca/Oxford vaccine seems to be decreasing over time, with a significant decrease when comparing December with March (p<0.0000000001, mean difference=-0.746, 95% CI=-0.915 to -0.577).
    Conclusion: Lexicon-based Twitter sentiment analysis is a valuable and easily implemented tool to track the sentiment regarding SARS-CoV-2 vaccines. It is worrisome that the sentiment regarding the AstraZeneca/Oxford vaccine appears to be turning negative over time, as this may boost hesitancy rates towards this specific SARS-CoV-2 vaccine.

    Abstract Objectives: Benzodiazepines (BZDs) are widely prescribed in Croatia to treat anxiety, insomnia, mood disorders, and epileptic seizures. Long-term BZD use is associated with memory loss, Alzheimer's disease, dependence, addiction, falls in elderly populations, and increased traffic accident risk.
    Methods: Drug consumption data were obtained from the Agency for Medicinal Products and Medical Devices of Croatia website. Autoregressive integrated moving average models, constructed using R programming language, forecasted diazepam, alprazolam, and overall BZD utilization and financial costs at a national level over 10 years.
    Results: BZD consumption increased by up to 18.6% between 2012 and 2020. During the same period, diazepam utilization rose by 29.1%, and alprazolam consumption increased by 19.4%. Our model predicts that, by 2032, BZD, diazepam, and alprazolam utilization will increase substantially. The total projected financial expenditure for BZDs in 2032 is estimated at 14.22 million euros, with diazepam and alprazolam expenditures at 7.39 and 4.12 million euros, respectively. These increases will result in significant growth in healthcare spending and a rise in adverse effects related to long-term use.
    Conclusions: National healthcare decision makers should consider implementing regulatory and legislative measures to quantify, specify, and limit monthly BZD use for each patient. This would help control the negative side effects of prolonged BZD use while continuing to provide treatment for patients who genuinely need it.
