Media hype: Patient and scientific perspectives on misleading medical news

Public Knowledge, Perceptions, and Behavioral Intention Regarding Medical Cannabis in Belgium

Growing evidence on medical cannabis has moved its legislation forward in various countries, which has increased research on stakeholder reactions. While various studies looked at experts and users, research on public perceptions is scarce. This study aims to (1) examine the relationships between knowledge, perceptions, and behavioral intention toward medical cannabis, and (2) identify and profile key segments within the general public. An online survey was conducted among 656 respondents in Belgium. Findings showed that both subjective and objective knowledge are relatively poor, while risk/benefit perceptions and behavioral intention are much more positive. Subjective and objective knowledge as well as social trust have a positive influence on benefit perceptions and a negative influence on risk perceptions. In turn, risk and benefit perceptions are key determinants of behavioral intention, but in opposite directions. Furthermore, cluster analysis identified a cautious (23% of the sample), positive (50%), and enthusiastic cluster (27%). In terms of socio-demographic profile, older and highly educated people were significantly more represented in the latter two clusters. While our study demonstrated that cannabis is well accepted for medical purposes, research is needed to further validate the relationships between knowledge, perceptions, and (intended) behavior in different settings and policy contexts.

Media Framing of Causes, Risks, and Policy Solutions for Cannabis-Impaired Driving: Does Medical vs. Non-Medical Cannabis Context Matter?

Driving under the influence of cannabis (DUIC) is a major cause of preventable death and a growing public health concern. News media coverage of DUIC may influence public perceptions of causal factors for DUIC, risks of DUIC, and potential policy solutions. This study examines Israeli news media coverage of DUIC, and contrasts media coverage according to whether news items refer to cannabis use for medical vs. non-medical purposes. We conducted a quantitative content analysis of news articles related to driving accidents and cannabis use (N = 299) from eleven of the highest circulation newspapers in Israel between 2008 and 2020. We apply attribution theory to analyze media coverage of accidents that were linked to medical cannabis, use compared with non-medical use. News items describing DUIC in the context of non-medical (vs. medical) cannabis use were more likely to: (a) emphasize individual causes (vs. social and political); (b) describe drivers in negative terms (vs. neutral or positive); (c) refer to an increased accident risk due to cannabis use (vs. inconclusive or low risk); and (d) call for increased enforcement rather than education. Results show that Israeli news media coverage of cannabis-impaired driving varied significantly depending on whether it referred to cannabis use for medical purposes, or non-medical purposes. News media coverage may influence public perceptions of the risks of DUIC, the factors that are associated with this issue, and potential policy solutions that may reduce the prevalence of DUIC in Israel.

Perceptions of the benefits of the basic medical insurance system among the insured: a mixed methods research of a northern city in China

Background

The perceptions of the benefits of the basic medical insurance system among the insured not only reflect the system's performance but also the public's basic medical insurance policy literacy, valuable information for countries that have entered the stage of deepening reform. This study aims to examine the factors that affect the perceptions of the benefits of the basic medical insurance system in China, diagnose the key problems, and propose corresponding measures for improvement.

Methods

A mixed method design was used. Data for the quantitative study were obtained from a cross-sectional questionnaire survey (n = 1,045) of residents of Harbin who had enrolled for basic medical insurance system. A quota sampling method was further adopted. A multivariate logistic regression model was then employed to identify the factors influencing the perceptions of the benefits of the basic medical insurance system, followed by semi-structured interviews with 30 conveniently selected key informants. Interpretative phenomenological analysis was used to analyze the interview data.

Results

Approximately 44% of insured persons reported low perceptions of benefits. The logistic regression model showed that low perceptions of the benefits of the basic medical insurance system was positively correlated with the experience of daily drug purchases (OR = 1.967), perceptions of recognition with basic medical insurance system (OR = 1.948), perceptions of the financial burden of participation costs (OR = 1.887), perceptions of the convenience of using basic medical insurance for medical treatment (OR = 1.770), perceptions of the financial burden of daily drug purchases costs (OR = 1.721), perceptions of the financial burden of hospitalization costs (OR = 1.570), and type of basic medical insurance system (OR = 1.456). The results of the qualitative analysis showed that the key problem areas of perceptions of the benefits of the basic medical insurance system were: (I) system design of basic medical insurance; (II) intuitive cognition of the insured; (III) rational cognition of the insured; and (IV) the system environment.

Conclusions

Improving the perceptions of the benefits of the basic medical insurance system of the insured requires joint efforts in improving system design and implementation, exploring effective publicity methods of basic medical insurance system information, supporting public policy literacy, and promoting the health system environment.

A Long Way to Go: Patient Perspectives on Digital Health for Parkinson's Disease

Digital health promises to improve healthcare, health, and wellness through the use of digital technologies. The purpose of this commentary is to review and discuss the field of digital health for Parkinson’s disease (PD) focusing on the needs, expectations, and wishes of people with PD (PwP). Our analysis shows that PwP want to use digital technologies to actively manage the full complexity of living with PD on an individual level, including the unpredictability and variability of the condition. Current digital health projects focusing on PD, however, does not live up to the expectations of PwP. We conclude that for digital health to reach its full potential, the right of PwP to access their own data needs to be recognised, PwP should routinely receive personalised feedback based on their data, and active involvement of PwP as an equal partner in digital health development needs to be the norm.

A systematic review on fake news research through the lens of news creation and consumption: Research efforts, challenges, and future directions

BACKGROUND

Although fake news creation and consumption are mutually related and can be changed to one another, our review indicates that a significant amount of research has primarily focused on news creation. To mitigate this research gap, we present a comprehensive survey of fake news research, conducted in the fields of computer and social sciences, through the lens of news creation and consumption with internal and external factors.

METHODS

We collect 2,277 fake news-related literature searching six primary publishers (ACM, IEEE, arXiv, APA, ELSEVIER, and Wiley) from July to September 2020. These articles are screened according to specific inclusion criteria (see Fig 1). Eligible literature are categorized, and temporal trends of fake news research are examined.

RESULTS

As a way to acquire more comprehensive understandings of fake news and identify effective countermeasures, our review suggests (1) developing a computational model that considers the characteristics of news consumption environments leveraging insights from social science, (2) understanding the diversity of news consumers through mental models, and (3) increasing consumers' awareness of the characteristics and impacts of fake news through the support of transparent information access and education.

CONCLUSION

We discuss the importance and direction of supporting one's "digital media literacy" in various news generation and consumption environments through the convergence of computational and social science research.

Content Analysis of Korean Videos Regarding Restless Legs Syndrome on YouTube

OBJECTIVE

To evaluate the accuracy and quality of Korean videos associated with restless legs syndrome (RLS) on YouTube.

METHODS

A YouTube search was performed on April 1, 2020 using the term "restless legs syndrome" in the Korean language. Two reviewers coded the source, content, and demographics of the included videos. Video quality was assessed using the modified DISCERN (mDISCERN) instrument.

RESULTS

Among the 80 videos analyzed, 44 (55.0%) were reliable, and 36 (45.0%) were misleading. There was a trend toward a higher number of mean daily views in the misleading videos than in the reliable videos. Most of the misleading videos (72.2%) advocated complementary and alternative medicine as a primary treatment for RLS. Although the reliable videos had higher mDISCERN scores than the misleading videos, the overall quality of the reliable videos was low.

CONCLUSION

Many Korean videos regarding RLS on YouTube involve a risk of exposure to misinformation and are of unsatisfactory quality.

Weeding through the haze: a survey on cannabis use among people living with Parkinson's disease in the US

Symptomatic management of Parkinson's disease (PD) is complex and many symptoms, especially non-motor symptoms, are not effectively addressed with current medications. In the US, cannabis has become more widely available for medical and recreational use, permitting those in the PD community to try alternative means of symptom control. However, little is known about the attitudes towards, and experiences with, cannabis use among those living with PD. To address this shortcoming, we distributed an anonymous survey to 7,607 people with PD in January 2020 and received 1339 responses (17.6%). 1064 complete responses were available for analysis. Respondents represented 49 states with a mean age of 71.2 years (±8.3) and mean PD duration of 7.4 years (±6.2). About a quarter of respondents (24.5%) reported cannabis use within the previous six months. Age and gender were found to be predictors of cannabis use in this sample (Age OR = 0.95, 95% CI 0.93 to 0.97; Male OR = 1.44, 95% CI 1.03 to 2.03). Users reported learning about cannabis use from the internet/news (30.5%) and friends or other people with PD (26.0%). Cannabis users were more likely to report insufficient control of their non-motor symptoms with prescription medications than non-users (p = 0.03). Cannabis was primarily used for PD (63.6%) and was most often used to treat nonmotor symptoms of anxiety (45.5%), pain (44.0%), and sleep disorders (44.0%). However, nearly a quarter of users (23.0%) also reported they had stopped cannabis use in the previous six months, primarily due to a lack of symptom improvement (35.5%). Three quarters of respondents (75.5%) did not use cannabis, primarily because there was a lack of scientific evidence supporting efficacy (59.9%). Our results suggest that the lack of formal guidance or research evidence about cannabis for PD may in part underlie inconsistencies in both use and reported effectiveness.

Clinical impact of high-profile animal-based research reported in the UK national press

OBJECTIVES

We evaluated animal-based biomedical 'breakthroughs' reported in the UK national press in 1995 (25 years prior to the conclusion of this study). Based on evidence of overspeculative reporting of biomedical research in other areas (eg, press releases and scientific papers), we specifically examined animal research in the media, asking, 'In a given year, what proportion of animal research "breakthroughs"' published in the UK national press had translated, more than 20 years later, to approved interventions?'

METHODS

We searched the Nexis media database (LexisNexis.com) for animal-based biomedical reports in the UK national press. The only restrictions were that the intervention should be specific, such as a named drug, gene, biomedical pathway, to facilitate follow-up, and that there should be claims of some clinical promise.

MAIN OUTCOME MEASURES

Were any interventions approved for human use? If so, when and by which agency? If not, why, and how far did development proceed? Were any other, directly related interventions approved? Did any of the reports overstate human relevance?

RESULTS

Overspeculation and exaggeration of human relevance was evident in all the articles examined. Of 27 unique published 'breakthroughs', only one had clearly resulted in human benefit. Twenty were classified as failures, three were inconclusive and three were partially successful.

CONCLUSIONS

The results of animal-based preclinical research studies are commonly overstated in media reports, to prematurely imply often-imminent 'breakthroughs' relevant to human medicine.

Comparison of Patient and Expert Perceptions of the Attainment of Research Milestones in Parkinson's Disease

Background

Commentators suggest that patients have unrealistic expectations about the pace of research advances and that such expectations interfere with patient decision‐making.

Objective

The objective of this study was to compare expert expectations about the timing of research milestone attainment with those of patients who follow Parkinson's disease (PD) research.

Methods

Patients with PD and experts were asked to provide forecasts about 11 milestones in PD research in an online survey. PD experts were identified from a Michael J. Fox Foundation database, highly ranked neurology centers in the United States and Canada, and corresponding authors of articles on PD in top medical journals. Patients with PD were recruited through the Michael J. Fox Foundation. We tested whether patient forecasts differed on average from expert forecasts. We also tested whether differences between patient forecasts and the average expert forecasts were associated with any demographic factors.

Results

A total of 256 patients and 249 PD experts completed the survey. For 9 of the 11 milestones, patients' forecasts were on average higher than those of experts. Only exercise therapy met our 10% difference threshold for practical significance. Education was the only demographic that predicted patient deviations from expert forecasts on milestone forecasts. Patients offered significantly higher forecasts than experts that the clinical trials used in milestone queries would report positive primary outcomes.

Conclusions

Differences between patient and expert expectations about research milestones were generally minor, suggesting that there is little cause for concern that patients who follow PD research are unduly swayed by inaccurate representations of research advancement in the media or elsewhere. © 2020 The Authors.

Human-Computer Interaction, Ethics, and Biomedical Informatics

Objectives : To provide an overview of recent work at the intersection of Biomedical Informatics, Human-Computer Interaction, and Ethics.

Methods : Search terms for Human-Computer Interaction, Biomedical Informatics, and Ethics were used to identify relevant papers published between 2017 and 2019.Relevant papers were identified through multiple methods, including database searches, manual reviews of citations, recent publications, and special collections, as well as through peer recommendations. Identified articles were reviewed and organized into broad themes.

Results : We identified relevant papers at the intersection of Biomedical Informatics, Human-Computer Interactions, and Ethics in over a dozen journals. The content of these papers was organized into three broad themes: ethical issues associated with systems in use, systems design, and responsible conduct of research.

Conclusions : The results of this overview demonstrate an active interest in exploring the ethical implications of Human-Computer Interaction concerns in Biomedical Informatics. Papers emphasizing ethical concerns associated with patient-facing tools, mobile devices, social media, privacy, inclusivity, and e-consent reflect the growing prominence of these topics in biomedical informatics research. New questions in these areas will likely continue to arise with the growth of precision medicine and citizen science.

"But Dr Google said…" - Training medical students how to communicate with E-patients

Purpose: Patients who have access to information online may feel empowered and also confront their physicians with more detailed questions. Medical students are not well-prepared for dealing with so-called "e-patients." We created a teaching module to deal with this, and evaluate its effectiveness.Method: Senior medical students had to manage encounters with standardized patients (SPE) in a cross-over design. They received blended-learning teaching on e-patients and a control intervention according to their randomization group (EI/LI = early/late intervention). Each SPE was rated by two blinded video raters, the SP and the student.Results: N = 46 students could be included. After the intervention, each group (EI, LI) significantly improved their competency in dealing with e-patients as judged by expert video raters (EI: M_T0 = 9.75 (2.51) versus M_T1 = 16.60 (2.80); LI: M_T0 = 8.70 (2.14) versus M_T2 = 15.20 (2.84); both p < 0.001) and SP (EI: M_T0 = 24.13 (4.83) versus M_T1 = 26.52 (3.06); LI: M_T0 = 23.37 (3.10) versus M_T2 = 27.47 (4.38); both p < 0.001). Students' rating showed a similar non-significant trend.Conclusions: Students, SP and expert video raters determined that blended-learning teaching can improve students' competencies when dealing with e-patients. Within the study period, this effect was lasting; however, further studies should look at long-term outcomes.

Targeting α-Synuclein in Parkinson's Disease: Progress Towards the Development of Disease-Modifying Therapeutics

Parkinson's disease (PD), the second most common neurodegenerative movement disorder, is characterized by progressive motor and non-motor symptoms [1]. Despite treatment with pharmacologic and surgical therapies, the disease will continue to relentlessly advance. Hence, there is a great deal of interest in potential disease-modifying therapies with the hope that the neurodegenerative process can be slowed or halted. The purpose of this review is to highlight the role toxic α-synuclein (α-syn) plays in PD pathogenesis and critically review the relevant literature about therapeutic modalities targeting α-syn. Toxic α-syn plays a key role in PD pathogenesis, disrupting important cellular functions, and, thus, targeting α-syn is a reasonable disease-modifying strategy. Current approaches under investigation include decreasing α-syn production with RNA interference (RNAi), inhibiting α-syn aggregation, promoting intracellular degradation of α-syn aggregates (via enhancing autophagy and enhancing lysosomal degradation), and promoting extracellular degradation of α-syn via active and passive immunization.

Participant perspectives on a phase I/II ocular gene therapy trial (NCT02077361)

Background: To learn from the experiences of potential clinical trial participants, participants in a Phase 1 ocular gene therapy trial, and their partners to improve communications and trial conduct. Materials and methods: Primary and secondary qualitative analysis of semi-structured interviews of potential participants (n = 20), clinical trial participants (n = 2) and their partners (n = 2) in a gene therapy clinical trial for choroideremia (NCT02077361). Analysis included: 1) thematic analysis of transcribed entrance and exit semi-structured interviews with trial participants and their partners; and 2) secondary qualitative analysis of interviews with potential trial participants, conducted prior to the initiation of the clinical trial. Results: Participants and partners who had received information during the consent process had a better understanding of the risks and benefits of participation in a Phase 1 gene therapy clinical trial than potential trial participants. However, participants and partners reported deficiencies in communication throughout the trial. Results highlight additional opportunities for trial staff to reinforce initial information about the trial, communicate logistical information and individual outcome data, and express appreciation for participation. Conclusions: Our study enabled clinical trial participants to describe their experiences in a clinical trial for a novel gene therapy. We provide practical recommendations to future clinical trial staff on communications and conduct participant perspectives. Communications strategies should address changing information needs over the course of the trial, express appreciation for participation and enable feedback from participants and their supporting family members, friends, or caregivers.

Pros and Cons of Marijuana in Treatment of Parkinson's Disease

Parkinson's disease (PD) is the second most common neurodegenerative disorder of adult onset in the United States. It is a debilitating condition and presents with both motor and non-motor symptoms. Current treatment options are scarce and include replacement of dopamine deficiency with levodopa which targets only motor symptoms of the disorder, does not halt its progression, and is associated with side effects of its own, including dyskinesia. With medical marijuana gaining popularity and being legalized in the United States, we examined the pros and cons of marijuana in the treatment of Parkinson's disease.

Medical Cannabis Use in Glioma Patients Treated at a Comprehensive Cancer Center in Florida

Background: Glioma is a devastating primary tumor of the central nervous system with difficult-to-manage symptoms. Cannabis products have been postulated to potentially benefit glioma patients. Recent state legalization allowed investigators an opportunity to study glioma patients' adoption of medical marijuana (MM). Objective: Our goals were to: (1) determine the prevalence of marijuana use, both through physician recommendation and self-medication, and (2) evaluate its perceived risks and benefits in glioma patients. Design: Self-report data were collected and descriptive analyses were conducted. Setting/Subjects: Participants were adult, English-speaking patients undergoing treatment for primary non-recurrent malignant glioma in neuro-oncology clinics at an NCI-designated Comprehensive Cancer Center. Measurements: The survey on MM was adapted from previous research and included questions on knowledge and attitudes toward MM; use, frequency, type, and sourcing of MM; and reasons for use of MM and perceived symptom relief among users. Results: A total of 73 patients were surveyed. The majority of participants were aware that MM was legal in the state, and most reported learning of this through the media. Over 70% of participants reported having considered using MM, and a third reported using marijuana products after their diagnosis. Most received recommendations from friends/family rather than a medical provider, and only half of the users had obtained a physician's recommendation. Users generally reported benefits. Conclusions: With the increasing national conversation that accompanies legalization, glioma patients are pursuing marijuana for the treatment for their symptoms. More research and education is needed to bring health care providers into the conversation.

Engagement with medical cannabis information from online and mass media sources: Is it related to medical cannabis attitudes and support for legalization?

BACKGROUND

The legalization of medical and recreational cannabis is a topic of continued debate in countries around the world. It has been suggested that medical cannabis legalization influences cannabis legalization for recreational purposes through increased media attention toward the positive health effects of cannabis. However, the nature of media coverage is likely to vary across mass media and online sources (internet and social media). In addition, effects of information engagement on attitudes may vary depending on whether information was actively sought or obtained incidentally during patterns of regular media use (scanned).

METHODS

This study uses data from an online survey of Israeli adults (N = 554) to test the association between information seeking and scanning about medical cannabis (from mass media and online sources) and attitudes toward medical cannabis. Furthermore, we test indirect effects of media engagement on attitudes toward cannabis legalization through medical cannabis attitudes.

RESULTS

Seeking and scanning for information about medical cannabis from online sources, but not from mass media sources, were associated with positive attitudes toward medical cannabis. Engagement with medical cannabis information from online sources was also indirectly associated with greater support for cannabis legalization, through positive attitudes related to medical cannabis.

CONCLUSION

The results suggest that one mechanism through which medical cannabis legalization is associated with cannabis legalization for all purposes is public engagement with information about medical cannabis in the media, particularly from the internet and social media channels. As increasingly more jurisdictions are expected to legalize medical cannabis, with resulting increase in media attention, support for recreational cannabis legalization may be expected to grow.

Examining effects of medical cannabis narratives on beliefs, attitudes, and intentions related to recreational cannabis: A web-based randomized experiment

BACKGROUND

This experimental study tests effects of exposure to video narratives about successful symptom relief with Medical Cannabis (MC) on attitudes, beliefs, and intentions related to recreational cannabis use.

METHODS

Patient video testimonials were modeled after those found in extant media coverage. Israeli participants (N = 396) recruited through an online survey company were randomly assigned to view a narrative or a non-narrative video containing equivalent information about MC. Video content was further manipulated based on whether the protagonist had a stigmatized disease or not, and whether attribution of responsibility for his disease was internal or external.

RESULTS

Exposure to patient testimonials indirectly increased positive attitudes, beliefs and intentions related to recreational cannabis use through changing attitudes, beliefs and intentions related to MC. Furthermore, exposure to narratives in which the patient was presented as not to blame for contracting his illness (external attribution) was associated with more positive attitudes, beliefs and intentions toward MC, a factor that was significantly associated with more positive attitudes, beliefs and intentions related to recreational cannabis use.

CONCLUSIONS

These results suggest that narrative news media coverage of MC may influence public attitudes toward recreational cannabis. Because such media stories continue to be commonplace, it is important to examine potential spillover effects of this coverage on public perceptions of recreational cannabis. Cannabis prevention programs should address the role of media coverage in shaping public opinion and address the distinction between medical and recreational cannabis use.

Progress toward an integrated understanding of Parkinson's disease

Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease, affecting over 10 million individuals worldwide. While numerous effective symptomatic treatments are currently available, no curative or disease-modifying therapies exist. An integrated, comprehensive understanding of PD pathogenic mechanisms will likely address this unmet clinical need. Here, we highlight recent progress in PD research with an emphasis on promising translational findings, including (i) advances in our understanding of disease susceptibility, (ii) improved knowledge of cellular dysfunction, and (iii) insights into mechanisms of spread and propagation of PD pathology. We emphasize connections between these previously disparate strands of PD research and the development of an emerging systems-level understanding that will enable the next generation of PD therapeutics.
