Amyloid PET disclosure in subjective cognitive decline: Patient experiences over time.

INTRODUCTION: We disclosed amyloid positron emission tomography (PET) results in individuals with subjective cognitive decline (SCD) and studied patient experiences and outcomes over a 6-month period. METHODS: Fifty-seven participants from the Subjective Cognitive Impairment Cohort (SCIENCe) (66 ± 8 years, 21 [37%] F, Mini-Mental State Examination 29 ± 1, 15 [26%] amyloid positive [A+]) completed questionnaires 1 week prior (T0), 1 day after (T1), and 6 months after amyloid PET disclosure (T2). Questionnaires addressed patient-reported experiences and outcomes. RESULTS: Independent of amyloid status, participants were satisfied with the consultation (scale 1-10; 7.9 ± 1.7) and information provided (scale 1-4; T1: 3.3 ± 0.9, T2: 3.2 ± 0.8). After 6 months, A+ participants reported more information needs (45% vs. 12%, p = 0.02). Independent of amyloid status, decision regret (scale 1-5; A+: 1.5 ± 0.9, A-: 1.4 ± 0.6, p = 0.53) and negative emotions (negative affect, uncertainty, anxiety) were low (all p > 0.15 and Pinteraction > 0.60). DISCUSSION: Participants with SCD valued amyloid PET disclosure positively, regardless of amyloid status. The need for information after 6 months, which was stronger in A+ individuals, underscores the importance of follow-up. HIGHLIGHTS: Participants with subjective cognitive decline (SCD) positively valued amyloid positron emission tomography (PET) disclosure. Participants with SCD experienced low levels of decision regret. We did not observe an increase in negative emotions. After 6 months, amyloid-positive individuals wanted more information.

Awareness and perceptions of contaminants in the Dehcho and sahtú regions of the Northwest Territories.

The development and dissemination of health messaging is a critical component of reducing health disparities. Participants (n = 87) from a human biomonitoring study in six Dene communities responded to a survey about health communication regarding contaminants. The survey included questions on awareness of health messages and risk perceptions related to country foods and contaminants. The vast majority of participants reported eating country foods (99%) and heard that country foods had beneficial nutrients (90%). Seventy per cent of respondents had heard or seen messages about fish with high levels of mercury, and 60% had concerns about the safety or quality of country foods they consumed. Respondents who reported decreasing the number of fish they ate since hearing the messages about fish and mercury had lower (p = 0.04) mercury concentration in hair, compared to those who had not heard the messages. However, no differences in hair mercury were observed for respondents who reported to have changed their fishing location, chosen smaller fish or eaten less predatory fish since hearing the messages. Results indicate the need to examine reasons for self-reported behaviour changes, in addition to awareness. The conclusions of this study can inform the development of messaging and risk management decisions about contaminants within Indigenous populations.

Gender differences in responses to an altruistic message regarding rubella vaccination.

Background: The supplementary immunization activity (SIA) for the rubella vaccination of adult men born between 1962 and 1978 began in 2019 in Japan because of a vaccine gap in the cohort, as vaccination was not mandatory for those born in that period. However, SIA coverage remains low, despite an active campaign and financial support. Methods: We conducted a randomized controlled study based on a 2 (scenario: self-vaccination, child vaccination) × 2 (message: self-interest, group-interest) factorial design, using a Japanese online panel. Participants with children were assigned to the child vaccination scenario in Intervention 1, whereas others were assigned to the self-vaccination scenario. After Intervention 1, all participants were given the same information about rubella. In Intervention 2, participants assigned to self-interest messages received a message emphasizing the risk of rubella, and those assigned to group-interest messages received a message emphasizing herd immunity. After Intervention 2, we evaluated the effects using a questionnaire. Results: Among the 2,206 participants, information regarding rubella was evaluated as more reliable in the group-than in the self-interest message condition, especially among women. Women evaluated the necessity of rubella vaccination for adult men and women to be higher in the child-vaccination scenario and group-interest messages. However, no differences were found among men. By contrast, men exposed to the self-interest message positively evaluated the reliability of the rubella explanation. Conclusion: The findings indicate that emphasizing self-interest messages is more effective for men in promoting herd immunity against rubella.

Improving Public Health Emergency Communication Along the U.S. Southern Border: Insights From a COVID-19 Pilot Campaign With Truck Drivers.

Tens of thousands of trucks cross the U.S.-Mexico border every day. Cross-border truckers' high mobility puts them at risk of acquiring and transmitting infectious diseases and creates challenges reaching them with emergency public health messaging due to their everchanging locations and limited English proficiency. Despite this community-level transmission risk and documented health disparities related to various infectious and noninfectious diseases experienced by truckers themselves, little has been published to provide practical recommendations on better reaching this audience through innovative outreach methods. This article describes a COVID-19 health promotion campaign that aimed to (1) identify, pilot test, and evaluate effective messages, channels, sources, and settings for reaching truckers on both sides of the U.S.-Mexico border and (2) build capacity and sustainability for messaging around future health emergencies. The pilot program ran for 6 weeks, June to August 2023, in three key commercial border crossings and delivered approximately 50,000,000 impressions, nearly 45% more impressions than expected. Considerations for practitioners include the areas of design, implementation, and evaluation. The results provide insight into how to design health promotion messages that resonate with cross-border truckers and how to place these messages where they will be seen, heard, and understood. This includes working effectively with community health workers (CHW), known locally as promotores; identifying local partners that allow CHW to set up onsite; and, working with partner organizations including employers. Practical insights for building evaluation metrics into traditional and grassroots outreach strategies to facilitate real-time optimization as well as continued learning across efforts are also described.

Psychosocial implications of learning amyloid PET results in an observational cohort.

INTRODUCTION: Information on the psychosocial impact of Alzheimer's disease (AD) biomarker testing in adults at risk of AD is needed to inform best practices for communicating biomarker results. METHODS: Ninety-nine cognitively unimpaired older adults learned amyloid positron emission tomography (PET) results (mean age = 72.0 ± 4.8, 95% White, 28% elevated amyloid). Linear mixed-effects regression models were used to test the main effects and interaction of PET result × time on psychosocial outcomes up to 6 months after learning results. RESULTS: A significant interaction of PET result × time was observed for concern about AD (ß = 0.28, p = 0.02) and intrusive thoughts and avoidance (ß = -0.82, p < 0.001). A main effect of PET result was observed for AD test-related distress (ß = 12.09, p < 0.001). DISCUSSION: Cognitively unimpaired adults learning elevated-amyloid PET results reported mildly intrusive thoughts/avoidance initially following disclosure, but these symptoms decreased over time. Concern about AD dementia and AD biomarker test-related distress remained higher in elevated-amyloid compared to non-elevated-amyloid participants. HIGHLIGHTS: Longitudinal assessment of psychosocial reactions after amyloid PET disclosure was conducted. Transient highly intrusive thoughts or avoidance after learning elevated amyloid results. Persistent test result-related distress after receiving elevated-amyloid results. There is increased concern about AD dementia after receiving elevated-amyloid results. Happiness and relief are experienced after receiving non-elevated-amyloid results.

Dynamics of natural hazard risk awareness: Panel analysis insights from Switzerland.

The analysis of risk awareness should be the initial stage in integrated natural hazard risk management to promote appropriate and effective measures for mitigating risks and strengthening social resilience inside the multi-risk framework. Nevertheless, earlier studies focused on cross-sectional data and overlooked the changes in risk awareness levels and associated independent variables with time. This study analyzes for the first time a balanced nationwide panel dataset of 1612 respondent-year observations from Switzerland (period 2015-2021, including the epidemic of COVID-19) to examine and compare the effects of potential independent variables on the four dimensions of natural hazard risk awareness (NHRA), ranging from the broadest dimension of Relevance to higher dimensions of Perceived Probability of an event, Perceived Threat to life and valuables, and Perceived Situational Threat. The analysis in this study incorporates multiple methods of Random-Effect Model (RE), Generalized Linear Model (GLM), and mediation analysis. Results show that NHRA increased in Switzerland to different extents (up to 23.24%) depending on the dimension. Event memory, perceived information impact and reported individual informed level appeared to be the most consistent independent variables positively influencing panel NHRA. Among these, perceived information impact as an important indicator of risk communication, was also found to serve as a mediator from risk preparedness to risk awareness. By encouraging residents to engage in "Begin Doing Before Thinking" (BDBT) programs to leverage subliminal effects and self-reflection, this study proposes that behavior-cognition feedback loops may facilitate a virtuous cycle. Our promising observations provide recommendations for an effective awareness-rising strategy design and suggest extensive insights from potential short-interval panel analysis in the future.

Subjective Probability Increases Across Communication Chains: Introducing the Probability Escalation Effect.

A severity effect has previously been documented, whereby numerical translations of verbal probability expressions are higher for severe outcomes than for non-severe outcomes. Recent work has additionally shown the same effect in the opposite direction (translating numerical probabilities into words). Here, we aimed to test whether these effects lead to an escalation of subjective probabilities across a communication chain. In four 'communication chain' studies, participants at each communication stage either translated a verbal probability expression into a number, or a number into a verbal expression (where the probability to be translated was yoked to a previous participant). Across these four studies, we found a general Probability Escalation Effect, whereby subjective probabilities increased with subsequent communications for severe, non-severe and positive events. Having ruled out some alternative explanations, we propose that the most likely explanation is in terms of communications directing attention towards an event's occurrence. Probability estimates of focal outcomes increase across communication stages.

The Use of Injury and Fatality Narratives to Convey Agricultural Safety and Health Messages and to Develop Effective Resources Through Collaborative, Multi-Disciplinary Approaches (Tell a Story, Save a Life).

OBJECTIVE: Storytelling engages audiences, passes down traditions and history, educates, and helps people understand and interpret their environment. Many of those who work in agriculture have been part of the storytelling tradition since childhood. Research has demonstrated the emotional impact of personal stories and how prevention information is conveyed effectively "farmer to farmer" through this method of communication. METHODS: Since 2016, the Telling the Story Project has provided a space for those directly or indirectly involved in an agricultural incident to share their story and unique perspectives on how similar incidents can be avoided. RESULTS: This collaborative project, developed between the National Institute for Occupational Safety and Health (NIOSH) Agriculture Safety Centers, has resulted in 11 stories on a dedicated website, safety and health resources, and educational guides. The stories and educational guidelines have been marketed extensively through traditional and social media sources, employed in safety training, and embraced by educators in agricultural programs. The website has provided a national and international reach with more than 35,000 visits. CONCLUSION: Qualitative thematic analysis of the stories provided data on the circumstances leading up to each incident, valuable information on how the storytellers interpreted the aftermath, and a novel perspective on how safety professionals can create messaging that will resonate with the farming community.

Why COVID-19 Symptomatic Patients Did Not Seek Healthcare Service at the Early Phase of the Pandemic in Bangladesh: Evidence From a Cross-Sectional Study.

Objective The health-seeking behavior (HSB) of patients during an outbreak is crucial in mitigating the spread of disease. Poor HSB can increase mortality and make contact tracing more difficult. In this study, we aimed to examine the status of HSB among Bangladeshi educated individuals during the early phase of the COVID-19 pandemic when infection was spreading quickly, and social distancing measures were tightened across the country. Methods We conducted a cross-sectional survey online among Bangladeshi individuals using a virtual snowball sampling method to capture suspected COVID-19 patients who did not undergo COVID-19 diagnostic testing. Descriptive and inferential analyses were performed with statistical significance defined as p<0.05. Results The study consisted of 390 participants with 44.9% having a bachelor's degree, followed by 25.9% with a master's or PhD degree. Commonly reported symptoms among the participants included fever (77.7%), cough (50.5%), headache (46.2%), body pain (36.4%), sore throat (35.6%), anosmia (31.3%), anorexia (13.8%), diarrhea (11.4%), and dyspnea (11.3%). The most common reasons for not taking the COVID-19 test were limited testing facilities (48%), the risk of infection from the test center (46%), fear of social stigma (19%), considering COVID-19 infection as innocuous (18%), and fear of forced quarantine (5%). In regression analysis, participants who lived in rural areas were found to be 2.5 times more likely to buy medications from nearby pharmacies. Males were more likely to self-medicate, with male participants being 3.2 times more likely than female participants to consider COVID-19 infection as harmless (AOR: 3.2, CI: 1.28-7.98). Smokers were more likely to seek help from government hotlines and to use drugs at home. Respondents with higher monthly income were less likely to fear forced quarantine (AOR: 0.27, CI: 0.4-2.02) but more likely to consider the risk of infection at the test center (AOR: 1.75, CI: 0.88-3.49). Conclusion Our study highlights that non-compliance with public health guidelines by educated people during an epidemic indicates a general lack of health literacy and distrust in the healthcare system. Along with improved infrastructure, efforts to enhance public health risk communication and health literacy are necessary to rebuild public trust in the healthcare service.

Developing and validating intracity spatiotemporal air quality health index in eastern China.

BACKGROUND: Recently pilot published city-level air quality health index (AQHI) provides a useful tool for communicating short-term health risks of ambient air pollution, but fails to account for intracity spatial heterogeneity in exposure and associated population health impacts. This study aims to develop the intracity spatiotemporal AQHI (ST-AQHI) via refined air pollution-related health risk assessments. METHODS: A three-stage analysis was conducted through integrating province-wide death surveillance data and high-resolution gridded estimates of air pollution and climate factors spanning 2016-2019 in Jiangsu Province, eastern China. First, an individual-level case-crossover design was employed to quantify the short-term risk of nonaccidental mortality associated with residential exposure to individual pollutant (i.e., PM2.5, NO2, O3, and SO2). Second, we accumulated and scaled the excess risks arising from multiple pollutants to formulate daily gridded ST-AQHI estimates at 0.1° × 0.1°, dividing exposure-related risks into low (0-3), moderate (4-6), high (7-9), and extreme high (10+) levels. Finally, the effectiveness of ST-AQHI as composite risk communication was validated through checking the dose-response associations of individual ST-AQHI exposure with deaths from nonaccidental and major cardiopulmonary causes via repeating case-crossover analyses. RESULTS: We analyzed a total of 1,905,209 nonaccidental death cases, comprising 785,567 from circulatory diseases and 247,336 from respiratory diseases. In the first-stage analysis, for each 10-µg/m3 rise in PM2.5, NO2, O3, and SO2 exposure at lag-01 day, population risk of nonaccidental death was increased by 0.8% (95% confidence interval: 0.7%, 0.9%), 1.9% (1.7%, 2.0%), 0.4% (0.3%, 0.5%), and 4.1% (3.7%, 4.5%), respectively. Spatiotemporal distribution of ST-AQHI exhibited a consistent declining trend throughout the study period (2016-2019), with annual average ST-AQHI decreasing from 5.2 ± 1.3 to 4.0 ± 1.0 and high-risk days dropping from 15.8% (58 days) to 1.6% (6 days). Exposure associated health risks showed great intracity- and between-city heterogeneities. In the validation analysis, ST-AQHI demonstrated approximately linear, threshold-free associations with multiple death events from nonaccidental and major cardiopulmonary causes, suggesting excellent performance in predicting exposure-related health risks. Specifically, each 1-unit rise in ST-AQHI was significantly associated with an excess risk of 2.0% (1.8%, 2.1%) for nonaccidental mortality, 2.3% (2.1%, 2.6%) for overall circulatory mortality, and 2.7% (2.3%, 3.1%) for overall respiratory mortality, as well as 1.7%-3.0% for major cardiopulmonary sub-causes. CONCLUSIONS: ST-AQHI developed in this study performed well in predicting intracity spatiotemporal heterogeneity of death risks related to multiple air pollutants, and may hold significant practical importance in communicating air pollution-related health risks to the public at the community scales.

Public Willingness to Mask and Vaccinate in the Future: Results From a 2023 Nationally Representative Survey of US Adults.

The enduring spread of COVID-19 and other respiratory viruses highlights a need for greater focus on long-term public willingness to perform protective behaviors. Although COVID-19 is no longer considered a public health emergency of international concern, it is unknown whether people in the United States plan to continue protective behaviors to protect themselves and others against infection. To inform planning and communications, we used a nationally representative survey of 1,936 US adults to examine attitudes and intentions toward future vaccination and mask-wearing. A majority believed COVID-19 vaccines were safe (73%) and effective in protecting against serious illness (72%). One-third (33%) had strong intentions to get an updated COVID-19 vaccine most years in the future. Among those with weaker intentions (n=1,287), many cited concerns about safety (71%) and efficacy (64%), lack of trust in institutions (64%), or beliefs that prior vaccination or infection protected them (62%). Approximately two-thirds (69%) of respondents believed masks were effective in protecting the wearer from getting COVID-19, and a majority appeared moderately receptive to future public mask-wearing, particularly when there was proximate risk of infection from COVID-19 (67%) or other respiratory viruses (59%). Men, non-Hispanic White adults, younger adults, rural residents, and adults with higher incomes, without college degrees, and without serious medical conditions or physical limitations were more likely to indicate resistance toward future COVID-19 vaccination and/or mask-wearing. Findings support tailored messaging to address concerns and opportunities among different populations, as well as support for communications programs and community engagement to motivate future uptake.

On the use of the term "real risk".

The term "real risk" and variations of this term are commonly used in everyday speech and writing, and in the scientific literature. There are mainly two types of use: i) in statements about what the real risk related to an activity is and ii) in statements about the risk related to an activity being real. The former type of use has been extensively discussed in the literature, whereas the latter type has received less attention. In the present study, we review both types of use and analyze and discuss potential meanings of type ii) statements. We conclude that it is reasonable to interpret a statement about the risk being real as reflecting a judgement that there is some risk and that the knowledge supporting this statement is relatively strong. However, such a statement does not convey whether the risk is small or large and needs to be supplemented by a characterization of the risk.

Updated review on contaminant communication experiences in the circumpolar Arctic.

Arctic populations are amongst the highest exposed populations to long-range transported contaminants globally, with the main exposure pathway being through the diet. Dietary advice is an important immediate means to address potential exposure and help minimize adverse health effects. The objective of this work is to enable easier access to dietary advice and communication guidance on contaminants with a focus on the Arctic. This manuscript is part of a special issue summarizing the Arctic Monitoring and Assessment Programme's Assessment 2021: Human Health in the Arctic. The information was derived with internet searches, and by contacting relevant experts directly. Results include risk communication efforts in European Arctic countries, effectiveness evaluation studies for several Arctic countries, experience of social media use, and the advantages and challenges of using social media in risk communication. We found that current risk communication activities in most Arctic countries emphasize the importance of a nutritious diet. Contaminant-related restrictions are mostly based on mercury; a limited amount of dietary advice is based on other contaminants. While more information on effectiveness evaluation was available, specific information, particularly from Arctic countries other than Canada, is still very limited.

Information needs persist after genetic counseling and testing for BRCA1/2 and Lynch Syndrome.

PURPOSE: Research has shown that cancer genetic risk is often not well understood by patients undergoing genetic testing and counseling. We describe the barriers to understanding genetic risk and the needs of high-risk persons and cancer survivors who have undergone genetic testing. METHODS: Using data from an internet survey of adults living in the USA who responded 'yes' to having ever had a genetic test to determine cancer risk (N = 696), we conducted bivariate analyses and multivariable logistic regression models to evaluate associations between demographic, clinical, and communication-related variables by our key outcome of having vs. not having enough information about genetics and cancer to speak with family. Percentages for yes and no responses to queries about unmet informational needs were calculated. Patient satisfaction with counseling and percentage disclosure of genetic risk status to family were also calculated. RESULTS: We found that a lack of resources provided by provider to inform family members and a lack of materials provided along with genetic test results were strongly associated with not having enough information about genetics and cancer (OR 4.54 95% CI 2.40-8.59 and OR 2.19 95% CI 1.16-4.14 respectively). Among participants undergoing genetic counseling, almost half reported needing more information on what genetic risk means for them and their family and how genetic testing results might impact future screening. CONCLUSION: High levels of satisfaction with genetic counseling may not give a full picture of the patient-provider interaction and may miss potential unmet needs of the patient. Accessible resources and ongoing opportunities for updating family history information could reinforce knowledge about genetic risk.

Risk Communication on Zoonoses and Antimicrobial Resistance-How Do Exotic Pet Owners Perceive the Communication of Their Veterinarians?

Exotic animals traded and kept as pets can transmit a variety of diseases to humans and other animals, and vice versa. Therefore, it is essential for pet owners, particularly vulnerable groups, to be informed about associated risks. Veterinarians play a crucial role in informing pet owners about health risks associated with zoonotic pathogens and antimicrobial resistance (AMR) and should, therefore, have good communication skills to effectively transfer information to pet owners. Thus, exotic pet owners in Germany were surveyed on animal husbandry, veterinary consultation and risk communication. To evaluate the perception of communication, a self-developed questionnaire was used to derive a communication score. The perception of veterinarian communication received a high average score showing a high level of satisfaction. The duration of the veterinarian-client relationship was associated with better communication perception, and the frequency of communication on zoonoses and AMR was associated with the presence of a permanent veterinarian. However, the results indicated that the frequency of disseminated information on zoonoses and/or AMR from veterinarians was lower than desired by the pet owners. Therefore, more educational material on zoonoses and AMR should be made available, and the awareness concerning risk communication should be increased by further education and training at universities.

Utilizing social media for community risk communication in megacities: analysing the impact of WeChat group information interaction and perception on communication satisfaction during the COVID-19 pandemic in Shanghai.

BACKGROUND: Against the backdrop of the global public health crisis, the COVID-19 pandemic has exposed significant disparities in the supply and demand of risk information related to public health crises, posing severe challenges to risk governance in megacities. Shanghai, China, introduced community WeChat groups for community communication, effectively facilitating the dissemination and response of grassroots information and providing a new path for interactive governance in the community. METHODS: This study collected 1006 questionnaires from residents of 350 communities in Shanghai through an online survey between June 10 and July 10, 2022. Multiple linear regression analysis was conducted to examine the impact of different participants (including the community, core residents, and the combined community and core residents) on community risk communication, perceived communication quality, and dissemination themes related to COVID-19 on community communication satisfaction. Additionally, in-depth interviews were conducted with 20 core residents from different types of communities, focusing on the specific methods of risk communication through community WeChat groups and their ability to disseminate information, respond to, and solve problems. RESULTS: Perceived information coverage and perceived response efficiency are significantly positively correlated with communication satisfaction. Notably, the speed of community information response has the greatest impact on communication satisfaction. Regarding COVID-19-related information dissemination themes, "community outbreaks, supplies, nucleic acids, outbreak prevention measures, and scientific content" all have a significant impact on communication effectiveness, with "nucleic acid testing information" having the greatest impact. Although the statistical data indicate that the participation of core residents in risk communication does not significantly affect communication satisfaction, it seems to be related to the size of the community, and the interview results further validate this conclusion. CONCLUSION: In the future, grassroots communities should consider the affordances of social media, recognize the significant correlation between risk communication and grassroots trust, and formulate more detailed and targeted risk communication strategies. In particular, incorporating core residents into "semiformal" grassroots organizations can improve community service quality, thereby enhancing community resilience in the face of public health emergencies.

Icon Arrays for Medical Risk Communication: Do Icon Type and Color Influence Cardiovascular Risk Perception and Recall?

BACKGROUND: Icon arrays have been shown to be an effective method for communicating medical risk information. However, in practice, icon arrays used to visualize personal risks often differ in the type and color of the icons. The aim of this study was to examine the influence of icon type and color on the perception and recall of cardiovascular risk, as little is known about how color affects the perception of icon arrays. METHODS: A total of 866 participants aged 40 to 90 years representative of the German population in terms of gender and age completed an online experiment. Using a 2 × 2 between-subjects design, participants were randomly assigned to 1 of 4 experimental groups. They received their hypothetical 10-year cardiovascular risk using an icon array that varied by icon type (smiley v. person) and color (black/white v. red/yellow). We measured risk perception, emotional response, intentions of taking action to reduce the risk (e.g., increasing one's physical activity), risk recall, and graph evaluation/trustworthiness, as well as numeracy and graphical literacy. RESULTS: Icon arrays using person icons were evaluated more positively. There was no effect of icons or color on risk perception, emotional response, intentions of taking action to reduce the risk, or trustworthiness of the graph. While more numerate/graphical literate participants were more likely to correctly recall the presented risk estimate, icon type and color did not influence the probability of correct recall. CONCLUSIONS: Differences in the perception of the tested icon arrays were rather small, suggesting that they may be equally suitable for communicating medical risks. Further research on the robustness of these results across other colors, icons, and risk domains could add to guidelines on the design of visual aids. HIGHLIGHTS: The use of different icons and colors did not influence the perception and the probability of recalling the 10-year cardiovascular risk, the emotional response, or the intentions to reduce the presented risk.Icon arrays with person icons were evaluated more positively.There was no evidence to suggest that the effectiveness of the studied icon arrays varied based on individuals' levels of numerical or graphical literacy, nor did it differ between people with or without a history of CVD or on medication for an increased CVD risk.

Trending ticks: using Google Trends data to understand tickborne disease prevention.

Introduction: Ticks and pathogens they carry seriously impact human and animal health, with some diseases like Lyme and Alpha-gal syndrome posing risks. Searching for health information online can change people's health and preventive behaviors, allowing them to face the tick risks. This study aimed to predict the potential risks of tickborne diseases by examining individuals' online search behavior. Methods: By scrutinizing the search trends across various geographical areas and timeframes within the United States, we determined outdoor activities associated with potential risks of tick-related diseases. Google Trends was used as the data collection and analysis tool due to its accessibility to big data on people's online searching behaviors. We interact with vast amounts of population search data and provide inferences between population behavior and health-related phenomena. Data were collected in the United States from April 2022 to March 2023, with some terms about outdoor activities and tick risks. Results and Discussion: Results highlighted the public's risk susceptibility and severity when participating in activities. Our results found that searches for terms related to tick risk were associated with the five-year average Lyme Disease incidence rates by state, reflecting the predictability of online health searching for tickborne disease risks. Geographically, the results revealed that the states with the highest relative search volumes for tick-related terms were predominantly located in the Eastern region. Periodically, terms can be found to have higher search records during summer. In addition, the results showed that terms related to outdoor activities, such as "corn maze," "hunting," "u-pick," and "park," have moderate associations with tick-related terms. This study provided recommendations for effective communication strategies to encourage the public's adoption of health-promoting behaviors. Displaying warnings in the online search results of individuals who are at high risk for tick exposure or collaborating with outdoor activity locations to disseminate physical preventive messages may help mitigate the risks associated with tickborne diseases.

Severity influences categorical likelihood communications: A case study with Southeast Asian weather forecasters.

Risk assessments are common in multiple domains, from finance to medicine. They require evaluating an event's potential severity and likelihood. We investigate the possible dependence of likelihood and severity within the domain of impact-based weather forecasting (IBF), following predictions derived from considering asymmetric loss functions. In a collaboration between UK psychologists and partners from four meteorological organisations in Southeast Asia, we conducted two studies (N = 363) eliciting weather warnings from forecasters. Forecasters provided warnings denoting higher likelihoods for high severity impacts than low severity impacts, despite these impacts being described as having the same explicit numerical likelihood of occurrence. This 'Severity effect' is pervasive, and we find it can have a continued influence even for an updated forecast. It is additionally observed when translating warnings made on a risk matrix to numerical probabilities.

Risk perception in long-term evacuees of Futaba town, Fukushima: a cross-sectional study reveals greater concerns outside the prefecture, 12 years after the accident.

For over 12 years since the 2011 East Japan Earthquake, the decontamination of radioactive materials is still incomplete. Although evacuation orders had been lifted in ~15% of Futaba town, the site of the Fukushima Daiichi Nuclear Power Plant, by August 2022, anxiety regarding the effects of nuclear radiation persists among evacuees, and their intention to return (ITR) remains low. As of August 2023, only 90 residents lived there. As the only town with government functions relocated outside Fukushima Prefecture, Futaba has more residents who evacuated outside the prefecture. Although numerous factors affect risk perception and ITR to the place of previous residence, the impact of evacuation destination on risk perception remains unknown. Therefore, this study aimed to evaluate the impact of evacuation destination on radiation risk perception. In 2022, a survey was conducted on 404 evacuees aged >18 years. The responses were compared between groups outside and inside Fukushima using the chi-square test and multivariate logistic regression analysis. Significant relationships were found between the evacuation destination and risk perception of genetic effects in the next generation (odds ratio [OR] = 1.92, 95% confidence interval [CI]: 1.15-3.20) and of the health effects of radiation (OR = 1.76, 95%CI: 1.10-2.84), which were both higher in those who had evacuated outside Fukushima. These findings stress the importance of evacuation destination choice and information access for evacuees' risk perception. Enhanced education and support efforts are necessary to help evacuees not only in Fukushima but also throughout Japan.
