Myth-busting the provider-user relationship for digital sequence information.
Ontology highlight
ABSTRACT: Background
The United Nations Convention on Biological Diversity (CBD) formally recognized the sovereign rights of nations over their biological diversity. Implicit within the treaty is the idea that mega-biodiverse countries will provide genetic resources and grant access to them and scientists in high-income countries will use these resources and share back benefits. However, little research has been conducted on how this framework is reflected in real-life scientific practice.Result
Currently, parties to the CBD are debating whether digital sequence information (DSI) should be regulated under a new benefit-sharing framework. At this critical time point in the upcoming international negotiations, we test the fundamental hypothesis of provision and use of DSI by looking at the global patterns of access and use in scientific publications.Conclusion
Our data reject the provider-user relationship and suggest a far more complex information flow for DSI. Therefore, any new policy decisions on DSI should be aware of the high level of use of DSI across low- and middle-income countries and seek to preserve open access to this crucial common good.

Project description:BackgroundCOVID-19 misinformation is a danger to public health. A range of formats are used by health campaigns to correct beliefs but data on their effectiveness is limited. We aimed to identify A) whether three commonly used myth-busting formats are effective for correcting COVID-19 myths, immediately and after a delay, and B) which is the most effective.MethodsWe tested whether three common correction formats could reduce beliefs in COVID-19 myths: (i) question-answer, ii) fact-only, (ii) fact-myth. n = 2215 participants (n = 1291 after attrition), UK representative of age and gender, were randomly assigned to one of the three formats. n = 11 myths were acquired from fact-checker websites and piloted to ensure believability. Participants rated myth belief at baseline, were shown correction images (the intervention), and then rated myth beliefs immediately post-intervention and after a delay of at least 6 days. A partial replication, n = 2084 UK representative, was also completed with immediate myth rating only. Analysis used mixed models with participants and myths as random effects.ResultsMyth agreement ratings were significantly lower than baseline for all correction formats, both immediately and after the delay; all β's > 0.30, p's < .001. Thus, all formats were effective at lowering beliefs in COVID-19 misinformation. Correction formats only differed where baseline myth agreement was high, with question-answer and fact-myth more effective than fact-only immediately; β = 0.040, p = .022 (replication set: β = 0.053, p = .0075) and β = - 0.051, p = .0059 (replication set: β = - 0.061, p < .001), respectively. After the delay however, question-answer was more effective than fact-myth, β = 0.040, p =. 031.ConclusionOur results imply that COVID-19 myths can be effectively corrected using materials and formats typical of health campaigns. Campaign designers can use our results to choose between correction formats. When myth belief was high, question-answer format was more effective than a fact-only format immediately post-intervention, and after delay, more effective than fact-myth format.

Project description:ObjectivesIn the United Kingdom, three people die every day awaiting an organ transplant. To address this, Scotland and England plan to follow Wales and introduce opt-out donor consent. However, emotional barriers, myths, and misconceptions may deter potential registrants. Our objectives were to estimate the number of people who plan to opt-out of the donor register and to test whether emotional barriers (e.g., medical mistrust) differentiated participants within this group. Finally, in an experimental manipulation, we tested whether intention to donate decreased by making emotional barriers more salient and increased following a widely used myth-busting intervention.DesignMixed between-within design.MethodsUK residents (n = 1,202) were asked whether they would choose opt-in, deemed consent, or opt-out/not sure if legislation changes to opt-out. Participants also completed measures of donor intentions at baseline, following a 12-item emotional barriers questionnaire and again, following a 9-item myth-busting intervention.ResultsFindings indicate that 66.1% of participants selected to opt-in to the donor register, 24.3% selected deemed consent, and 9.4% selected opt-out/not sure. Emotional barriers, notably fears surrounding bodily integrity, were significantly elevated in participants who selected opt-out/not sure. Increasing the salience of emotional barriers reduced donor intentions in the opt-out/not sure group. However, dispelling organ donation myths did not increase intention within this group.ConclusionsIf opt-out legislation is introduced in Scotland and England, approximately 10% of participants plan to opt-out or are not sure. Dispelling organ donation myths with facts may not be the best method of overcoming emotional barriers and increasing donor intentions for those planning to opt-out. Statement of contribution What is already known about this subject? In the United Kingdom, three people die every day waiting for an organ transplant. Although 90% of the UK population support organ donation, only 38% are registered donors. To address this, Scotland and England have recently proposed to introduce an opt-out system of donor consent. To date, limited research has investigated public attitudes and intentions regarding opt-out consent laws in Scotland and England. Emotional barriers (e.g., medical mistrust) are key factors that may deter potential registrants. However, no research has examined these barriers in relation to proposed opt-out consent laws. Myth-busting is widely used around the world as part of campaigns promoting organ donation. The NHS currently use a myth-busting feature on their webpage to dispel harmful myths about organ donation; however, there is limited evidence of the impact this has on intentions to become an organ donor. What does this study add? Approximately 10% of UK participants plan to opt-out or are unsure of their decision, if the law changes to opt-out. Emotional barriers, notably, bodily integrity fears, are significantly elevated in people who plan to opt-out. Increasing the salience of emotional barriers reduced donor intentions for people who plan to opt-out. A myth-busting intervention had no effect on donor intentions for people who plan to opt-out of the donor register.

Project description:We sought to determine if clinical data validate the dogma that bactericidal antibiotics are more clinically effective than bacteriostatic agents. We performed a systematic literature review of published, randomized, controlled trials (RCTs) that compared a bacteriostatic agent to a bactericidal agent in the treatment of clinical, bacterial infections. Of 56 identified trials published since 1985, 49 found no significant difference in efficacy between bacteriostatic and bactericidal agents. In 6 trials it was found that the bacteriostatic agent was superior to the bactericidal agent in efficacy. Only 1 trial found that the bactericidal agent was superior; in that case, the inferiority of the static agent was explainable by underdosing of the drug based on pharmacokinetic-pharmacodynamic analysis. Thus, virtually all available data from high-quality, RCTs demonstrate no intrinsic superiority of bactericidal compared to bacteriostatic agents. Other drug characteristics such as optimal dosing, pharmacokinetics, and tissue penetration may be more important efficacy drivers.

Project description:Monosodium glutamate (MSG), also referred to as Vetsin or E621, is a flavour enhancer frequently used in Asian cuisine and abundantly present in the famous Chinese dish Peking duck. MSG is notorious for triggering the onset of the so-called 'Chinese restaurant syndrome' (CRS), a complex of unpleasant symptoms, which might include flushing, sweating and the onset of atrial fibrillation (AF). This study aims to determine the effects of MSG on the occurrence of AF.We conducted a placebo self-controlled single-arm study in the Academic Medical Centre in Amsterdam. We included paroxysmal AF patients who reported a consistent onset of AF upon MSG intake. During three admissions, participants were subsequently administered: placebo, 1.5?g and 3?g MSG. If AF was recorded after the dose of 1.5?g MSG, patients were given another placebo instead of 3?g MSG. The primary outcome was the onset of AF registered by 24-hour Holter monitoring. The secondary outcomes were any other arrhythmia and the onset of CRS defined as two or more symptoms of CRS after MSG intake.Six men participated in the study. Both 1.5?g and 3?g MSG were unrelated to CRS, arrhythmias or AF occurrence.Peking duck can be put on the Christmas menu without risking guests to be admitted to the emergency department with new episodes of AF.

Project description:Ever since the introduction of the Watson-Crick model, numerous efforts have been made to fully characterize the digital information content of the DNA. However, it became increasingly evident that variations of DNA configuration also provide an "analog" type of information related to the physicochemical properties of the DNA, such as thermodynamic stability and supercoiling. Hence, the parallel investigation of the digital information contained in the base sequence with associated analog parameters is very important for understanding the coding capacity of the DNA. In this paper, we represented analog information by its thermodynamic stability and compare it with digital information using Shannon and Gibbs entropy measures on the complete genome sequences of several bacteria, including Escherichia coli (E. coli), Bacillus subtilis (B. subtilis), Streptomyces coelicolor (S. coelicolor), and Salmonella typhimurium (S. typhimurium). Furthermore, the link to the broader classes of functional gene groups (anabolic and catabolic) is examined. Obtained results demonstrate the couplings between thermodynamic stability and digital sequence organization in the bacterial genomes. In addition, our data suggest a determinative role of the genome-wide distribution of DNA thermodynamic stability in the spatial organization of functional gene groups.

Project description:BACKGROUND:"Digital Partners" is an intergenerational information and communications technology learning project carried out in the municipalities of Vic and Centelles (Catalonia) from April to May 2018. Within the framework of the introduction of community service as a subject in secondary education, the Centre for Health and Social Studies (University of Vic) created a training space with 38 intergenerational partners (aged 14-15 years and >65 years), with the aim of improving the senior users' digital skills in terms of use of smartphones and tablets, thus helping reduce the digital divide in the territory. OBJECTIVE:The aim of this paper is to evaluate the satisfaction of both junior and senior participants toward the intervention and to explore its main drivers. METHODS:Participants who volunteered to participate in the study were interviewed. Quantitative and qualitative data gathered in paper-based ad hoc surveys were used to assess participants' satisfaction. RESULTS:The experience shows a broad satisfaction of both junior and senior users. The project's strengths include the format of working in couples; randomly pairing individuals by operating system; the ability to practice with the device itself; individuals' free choice to decide what they wish to learn, develop, or practice; and the availability of voluntary practice material that facilitates communication and learning. With regard to aspects that could be improved, there is a need to review the timetabling flexibility of meetings to avoid hurrying the elderly and to extend the project's duration, if necessary. CONCLUSIONS:This activity can serve to create mutual learning through the use of mobile devices and generate security and motivation on the part of the seniors, thus reducing the digital divide and improving social inclusion.

Project description:It is a common belief that reptile eggs should not be turned after oviposition once the embryo has attached itself to the inner membrane of the shell as it might kill developing embryos. Here, we used 338 eggs from 32 clutches of the water snake Natrix maura to (1) thoroughly describe natural clutch arrangement, (2) experimentally assess the effects of natural embryo positioning and (3) egg turning on embryo metabolism, hatching success, and hatchling phenotype. Clutches contained, on average, 59% of embryos located at the top, 28% at the bottom, and 14% on a side of the egg. Larger females laid larger clutches with higher proportion of top located embryos. Top embryos displayed higher metabolic rates (heart rates), shorter incubation time, and produced lighter and shorter snakes than bottom embryos. Egg turning did not significantly influence egg development, hatching success or hatchling phenotypes. However, post-birth mortality was significantly higher in turned (37.5%) compared to unturned (4.5%) embryos, providing support to the common belief that eggs should not be moved from their natural position.

Project description:The Sharing Economy (SE) is a growing ecosystem focusing on peer-to-peer enterprise. In the SE the information available to assist individuals (users) in making decisions focuses predominantly on community-generated trust and reputation information. However, how such information impacts user judgement is still being understood. To explore such effects, we constructed an artificial SE accommodation platform where we varied the elements related to hosts' digital identity, measuring users' perceptions and decisions to interact. Across three studies, we find that trust and reputation information increases not only the users' perceived trustworthiness, credibility, and sociability of hosts, but also the propensity to rent a private room in their home. This effect is seen when providing users both with complete profiles and profiles with partial user-selected information. Closer investigations reveal that three elements relating to the host's digital identity are sufficient to produce such positive perceptions and increased rental decisions, regardless of which three elements are presented. Our findings have relevant implications for human judgment and privacy in the SE, and question its current culture of ever increasing information-sharing.

Project description:BACKGROUND:Innovation spread is a key policy objective for health systems world-wide, but adoption success varies enormously. We have developed a set of short generic user-reported measures to help understand how and why healthcare innovations spread. This work builds on the literature and on practical experience in developing and using patient-reported outcome measures. MEASURES:The Innovation Readiness Score measures user perceptions of how much they are open to and up-to-date with new ideas, and whether their organisations are receptive to and capable of innovation. It is based on Rogers' classification of innovativeness (innovator, early adopter, early majority, etc).The Digital Confidence Score rates users' digital literacy and confidence to use digital products, with dimensions of familiarity, social pressure, support and digital self-efficacy.The Innovation Adoption Score rates the adoption process in terms of coherence and reflective thought before, during and after implementation. It is based on Normalisation Process Theory.The User Satisfaction measure assesses a digital product in terms of usefulness, ease of use, support and satisfaction.The Behaviour Change measure covers user perceptions of their capability, opportunity and motivation to change behaviour, based on the COM-B model.These measures have been mapped onto Greenhalgh's NASSS Framework (non-adoption, abandonment and challenges to scale-up, spread and sustainability of health and care technologies). CONCLUSION:These tools measure different aspects of digital health innovations and may help predict the success of innovation dissemination, diffusion and spread programmes.

Project description:ObjectivesThe objective of this randomised controlled trial in Kenya was to assess the effect of delivering sexual and reproductive health (SRH) information via text message to young people on their ability to reject contraception-related myths and misconceptions.Design and settingA three-arm, unblinded randomised controlled trial with a ratio of 1:1:1 in Kwale County, Kenya.Participants and interventionsA total of 740 youth aged 18-24 years were randomised. Intervention arm participants could access informational SRH text messages on-demand. Contact arm participants received once weekly texts instructing them to study on an SRH topic on their own. Control arm participants received standard care. The intervention period was 7 weeks.Primary outcomeWe assessed change myths believed at baseline and endline using an index of 10 contraception-related myths. We assessed change across arms using difference of difference analysis.ResultsAcross arms, <5% of participants did not have any formal education, <10% were living alone, about 50% were single and >80% had never given birth. Between baseline and endline, there was a statistically significant drop in the average absolute number of myths and misconceptions believed by intervention arm (11.1%, 95% CI 17.1% to 5.2%), contact arm (14.4%, 95% CI 20.5% to 8.4%) and control arm (11.3%, 95% CI 17.4% to 5.2%) participants. However, we observed no statistically significant difference in the magnitude of change across arms.ConclusionsWe are unable to conclusively state that the text message intervention was better than text message 'contact' or no intervention at all. Digital health likely has potential for improving SRH-related outcomes when used as part of multifaceted interventions. Additional studies with physical and geographical separation of different arms is warranted.Trial registration numberISRCTN85156148.
