Memory T-cell responses following SARS-CoV-2 infection have been extensively investigated but many studies have been small with a limited range of disease severity. Here we analyze SARS-CoV-2 reactive T-cell responses in 768 convalescent SARS-CoV-2-infected (cases) and 500 uninfected (controls) Icelanders. The T-cell responses are stable three to eight months after SARS-CoV-2 infection, irrespective of disease severity and even those with the mildest symptoms induce broad and persistent T-cell responses. Robust CD4+ T-cell responses are detected against all measured proteins (M, N, S and S1) while the N protein induces strongest CD8+ T-cell responses. CD4+ T-cell responses correlate with disease severity, humoral responses and age, whereas CD8+ T-cell responses correlate with age and functional antibodies. Further, CD8+ T-cell responses associate with several class I HLA alleles. Our results, provide new insight into HLA restriction of CD8+ T-cell immunity and other factors contributing to heterogeneity of T-cell responses following SARS-CoV-2 infection.
FinTech Development and Regulatory Scrutiny: A Contradiction? The Case of Latvia
(2022-08-23) Rupeika-Apoga, Ramona; Wendt, Stefan
The purpose of this study is to examine whether FinTech companies believe that the growing dependence on regulation represents a potential risk for their development. In 2021, we conducted a survey among Latvian FinTech companies to ascertain their attitude toward regulatory scrutiny. We received 31 responses, representing a 33% response rate. The responses show that regulation is still one of the most pressing issues for FinTech companies, even though it is not necessarily regulation per se that causes concerns, but the lack of a regulatory framework that would be suitable for the special situation of the FinTech sector. However, regulation is now regarded as less problematic than it was in a previous survey in 2019, when respondents saw regulation as the most pressing issue. Moreover, the FinTech industry anticipates better support from the regulator, such as more realistic sandbox approaches and a willingness to consider new business models. According to the survey responses, the UK, Estonian, and Lithuanian regulators can serve as inspiration in this regard. Latvian FinTech companies expect regulators to be more flexible and open in their communication. This study is intended to advance regulatory reform by aiding the understanding of the requirements of fast-evolving FinTech companies.
How Much Information Do Icelandic Men Receive on Pros and Cons of Prostate-Specific Antigen Testing Prior to Undergoing Testing?
(2022-05-25) Eiriksdottir, Valgerdur Kristin; Baldursdottir, Birna; Fridriksson, Jon Orn; Valdimarsdottir, Heiddis B.; Department of Psychology
Prostate-specific antigen (PSA) testing for asymptomatic men is neither encouraged nor discouraged in most countries; however, shared decision-making is emphasized prior to PSA testing. The objective of this study was to examine to what extent Icelandic men receive information about the pros and cons of PSA testing. Furthermore, to explore if patient–provider communication about pros and cons of PSA testing has improved in the last decade during which time more emphasis has been placed on shared decision-making. All Icelandic men diagnosed with prostate cancer in the years 2015 to 2020 were invited to participate, and a total of 471 out of 1002 men participated (response rate 47.0%). Participants’ age ranged from 51 to 95 years (M = 71.9, SD = 7.3). Only half of the men received information about the pros and cons of PSA testing, a third did not receive any information prior to testing and, alarmingly, 22.2% of the men did not even know that they were being tested. A majority of the participants lacked knowledge about the testing with half of the men reporting that they had no knowledge about pros and cons of PSA testing prior to testing. The findings have major public health relevance as they indicate that information provided prior to PSA testing continue to be deficient and that there is a pressing need for interventions that educate men about the benefits and limitations of PSA testing before men undergo medical procedures that can seriously affect their quality of life.
A year of Covid-19 : Experiences and lessons learnt by small European island states - Cyprus, Iceland and Malta

Background: COVID-19 became a global pandemic within weeks, as every country including small states and islands experienced a surge in cases. Small islands are known to face several challenges in the quest to curb the viral spread, but with the absence of land boarders and small population size, these factors should have played to their advantage to minimize the spread. The aim of this article was to compare and contrast the COVID19 situation, restrictions, preparedness, management and the healthcare systems between the small population island states of Cyprus, Iceland and Malta. Methods: Data were obtained from Ministry of Health websites and COVID dashboards of the three respective Island states in Europe. Comparisons were made between the reported cases, deaths, excess deaths, years of life lost, swabbing rates, restrictive measures, vaccination roll-out and healthcare system structures. Results: Cyprus and Malta contained the COVID-19 spread better than Iceland during the first wave. However, a significantly higher viral spread and mortality rates were observed in Malta during the second waves. Similar healthcare preparedness and services, restrictions and relaxation measures were implemented across the three islands with some exceptions. Covid-19 vaccination has initiated across all Islands with Malta leading the vaccination roll-out. Conclusion: The small population size and island status proved to be an asset during the first wave of COVID-19, but different governance approaches led to a different COVID-19 outcomes, including high mortality rates during the transition phases and the subsequent waves.
Investor Characteristics and their Impact on the Decision to use a Robo-advisor
(2022) Oehler, Andreas; Horn, Matthias; Wendt, Stefan
We survey 231 undergraduate students to analyze how retail investors’ characteristics influence their decision to use a robo-advisor. Characteristics such as the willingness to take risk, extraversion, and optimism are significant in univariate tests but the willingness to take risk and the internal locus of control are significant in multivariate settings. Participants who use the robo-advisor invest more and are more likely to also invest on their own in both stocks and bonds. We also find statistically significant differences between participants who exclusively use the robo-advisor for investments in stocks and bonds and participants who use the robo-advisor and invest some money in stocks and bonds on their own.
