RESUMEN

OBJECTIVE: To evaluate the provision of imaging at diagnosis of myeloma from the service user perspective with a specific focus on how the experiences of patients align with the National Institute for Health and Care Excellence (NICE) guidelines (NG35, 2016) on first-line imaging practice for myeloma in the United Kingdom. METHODS: A national survey was performed to evaluate access to imaging from the patient's perspective. Patients with myeloma who received their diagnosis between 2017 and March 2022 were invited to participate. Data were collected using an online survey from 895 patients and carers between 4 and 14 March 2022. RESULTS: Most patients had more than one imaging test. First-line MRI was used in 69.2% of respondents. First-line skeletal survey (SS, whole body X-rays) remained common (48.7% of respondents). 18F-fluorodexyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was used least often (23.1% of respondents). SS was used more often in East England (57.9%) and Scotland (61.2%) than in South East England (36.3%). CONCLUSIONS: Despite NICE recommendations, first-line MRI was not used in a third of patients surveyed, with geographical variation in imaging practice. Patients are still undergoing multiple imaging tests at diagnosis. Healthcare professionals should continue to emphasize the superiority of MRI compared to SS to drive for improvements in care. ADVANCES IN KNOWLEDGE: Current recommendations on first-line imaging for myeloma are not provided consistently across the United Kingdom. There is a need to drive change and support healthcare professionals to deliver guidance-based recommendations to improve experience and outcomes for patients.

RESUMEN

Health-related misinformation is a major threat to public health and particularly worrisome for populations experiencing health disparities. This study sets out to examine the prevalence, socio-psychological predictors, and consequences of beliefs in COVID-19 vaccine misinformation among unvaccinated Black Americans. We conducted an online national survey with Black Americans who had not been vaccinated against COVID-19 (N = 800) between February and March 2021. Results showed that beliefs in COVID-19 vaccine misinformation were prevalent among unvaccinated Black Americans with 13-19% of participants agreeing or strongly agreeing with various false claims about COVID-19 vaccines and 35-55% unsure about the veracity of these claims. Conservative ideology, conspiracy thinking mind-set, religiosity, and racial consciousness in health care settings predicted greater beliefs in COVID-19 vaccine misinformation, which were associated with lower vaccine confidence and acceptance. Theoretical and practical implications of the findings are discussed.

RESUMEN

Four-dimensional flow MRI is a powerful phase contrast technique used for assessing three-dimensional (3D) blood flow dynamics. By acquiring a time-resolved velocity field, it enables flexible retrospective analysis of blood flow that can include qualitative 3D visualization of complex flow patterns, comprehensive assessment of multiple vessels, reliable placement of analysis planes, and calculation of advanced hemodynamic parameters. This technique provides several advantages over routine two-dimensional flow imaging techniques, allowing it to become part of clinical practice at major academic medical centers. In this review, we present the current state-of-the-art cardiovascular, neurovascular, and abdominal applications.

RESUMEN

BACKGROUND: Guided by the 5C (confidence, complacency, constraints, calculation, and collective responsibility) model of vaccination behavior, we examine the psychological antecedents of COVID-19 vaccine acceptance (i.e. attitudes and intentions toward COVID-19 vaccination) among Black Americans, a group disproportionately affected by the coronavirus pandemic. METHOD: We conducted a national survey of Black Americans (N = 1,497) in February/March 2021. RESULTS: We found that, among the five psychological antecedents, three (confidence, calculation - or extensive information searching, and collective responsibility) significantly predicted attitudes toward COVID-19 vaccination and had indirect effects on vaccination intentions through vaccination attitudes. Two antecedents (confidence and collective responsibility) also directly predicted vaccination intentions. Our analysis suggests that a partially mediated model produced better fit than a fully mediated model. CONCLUSIONS: Developing culturally tailored interventions for Black Americans that build confidence in COVID-19 vaccines, highlight collective responsibility, and attend to Black Americans' information sources is key to boosting Black Americans' COVID-19 vaccine acceptance. Future research is needed to understand how historical and ongoing racism affects the psychological antecedents of COVID-19 vaccine acceptance among Black Americans.

RESUMEN

Stanford type B aortic dissection (TBAD) is a potentially fatal condition involving a tear in the descending aorta. As TBAD can be managed with medical therapy or surgical repair, identifying predictors of adverse outcomes is important to risk-stratify patients for preemptive surgical procedures. 4D flow magnetic resonance imaging (MRI) has shown to be useful in characterizing the complex hemodynamics seen in TBAD patients and correlating flow patterns with adverse outcomes. We report a case of a 58-year-old man who presented to the hospital with acute TBAD and a large primary entry tear. He was initially managed with medical therapy due to his stable clinical status and computed tomographic angiography showing a stable dissection. However, 4D flow MRI showed high velocity flow through the entry tear, which foreshadowed the later clinical decompensation of the patient. Our case demonstrates that performing 4D flow MRI on TBAD patients is feasible and can provide valuable information in the decision to pursue medical or surgical management.

RESUMEN

Immunomodulation by colchicine is a well-established therapy for targeting inflammatory pathways in gout, pericarditis and Behchet's disease. In more recent times, evidence has emerged demonstrating a potential role for colchicine in several cardiac conditions. This article aims to summarise the evidence behind the established guidelines for use of low-dose colchicine in pericarditis and examine the evolving evidence for its use in cardiovascular disease and most recently COVID-19.

RESUMEN

In this study we examine the role of moral values in predicting COVID-19 vaccine hesitancy among Black Americans. Guided by moral foundations theory, we assess the associations between six moral foundations (care, fairness, loyalty, authority, purity, liberty) and attitudes and intentions toward COVID-19 vaccination. Results of a national survey of Black Americans (N = 1,497) indicate that the care and loyalty moral foundations consistently predicted less vaccine hesitancy with overall more favorable attitudes and intentions toward COVID-19 vaccination, whereas the purity and liberty moral foundations were consistently associated with greater vaccine hesitancy. Relationships between the foundations and vaccine hesitancy were mediated by perceived vaccine effectiveness and safety. Implications of the findings for COVID-19 vaccine communication are discussed.

RESUMEN

The COVID-19 pandemic brought widespread attention to an "infodemic" of potential health misinformation. This claim has not been assessed based on evidence. We evaluated if health misinformation became more common during the pandemic. We gathered about 325 million posts sharing URLs from Twitter and Facebook during the beginning of the pandemic (March 8-May 1, 2020) compared to the same period in 2019. We relied on source credibility as an accepted proxy for misinformation across this database. Human annotators also coded a subsample of 3000 posts with URLs for misinformation. Posts about COVID-19 were 0.37 times as likely to link to "not credible" sources and 1.13 times more likely to link to "more credible" sources than prior to the pandemic. Posts linking to "not credible" sources were 3.67 times more likely to include misinformation compared to posts from "more credible" sources. Thus, during the earliest stages of the pandemic, when claims of an infodemic emerged, social media contained proportionally less misinformation than expected based on the prior year. Our results suggest that widespread health misinformation is not unique to COVID-19. Rather, it is a systemic feature of online health communication that can adversely impact public health behaviors and must therefore be addressed.

RESUMEN

'Trust is among the most important factors in human life, as it pervades' all domains of society [1] and related decision-making processes. This includes people's trust in science, and in clinical and public health solutions. Unequivocally, community and patient trust are foundational to the adoption and maintenance of health-related behaviors, social norms, and policies. Yet, trust has to be earned and developed over time and through multiple interactions. Trust is about dialogue and human connection. It's about listening and knowing that one interaction will not be enough to build trust. It is also influenced by a variety of social, economic, cultural, and political factors, past experiences, and the history of specific communities and patient groups. It should be at the core of the health and social systems with which people interact. More recently, trust in evidence-based information has also been affected by misinformation, not only on social media but also in a variety of community, institutional, and patient settings. Ultimately, we are in the midst of a global trust crisis that precedes the COVID-19 pandemic and is often rooted in the health, racial, and social inequities many groups experience [2].

RESUMEN

OBJECTIVE: Examine predictors of social media use among a nationally representative sample of adults with children in the household. METHODS: Data were collected from the Health Information National Trends (HINTS) Survey from 2017 to 2020 (N = 3559). Multivariate logistic regression models assessed the association between sociodemographic variables and social networking site (SNS) use, SNS use to share health information, participation in online forum or support groups for health issues and watching health-related videos on YouTube. RESULTS: Older adults and men were significantly less likely to use social media (p<.05). Non-Hispanic African American (aOR: 1.83; 95%CI: 1.30-2.57), Hispanic (aOR: 2.16; 95%CI: 1.56-2.99), and Asian (aOR: 2.82; 95%CI: 1.67-4.75) adults were more likely to watch health-related videos on YouTube. CONCLUSIONS: Racial/ethnic minorities with children in the household were more likely to seek health information on YouTube, highlighting opportunities to disseminate culturally relevant, accurate messages on the platform. Effective health communication targeted to specific demographics can help counter misinformation and promote health behavior particularly during public health emergencies. PRACTICE IMPLICATIONS: Providers need to foster trust so that patients are comfortable to ask questions in addition to seeking information online. Providers can direct patients to credible resources to counter misinformation exposure and promote healthy behavior.

RESUMEN

Coordination of efforts to assess the challenges and pain points felt by industries from around the globe working to reduce COVID-19 transmission in the indoor environment as well as innovative solutions applied to meet these challenges is mandatory. Indoor infectious viral disease transmission (such as coronavirus, norovirus, influenza) is a complex problem that needs better integration of our current knowledge and intervention strategies. Critical to providing a reduction in transmission is to map the four core technical areas of environmental microbiology, transmission science, building science, and social science. To that end a three-stage science and innovation Summit was held to gather information on current standards, policies and procedures applied to reduce transmission in built spaces, as well as the technical challenges, science needs, and research priorities. The Summit elucidated steps than can be taken to reduce transmission of SARS-CoV-2 indoors and calls for significant investments in research to enhance our knowledge of viral pathogen persistence and transport in the built environment, risk assessment and mitigation strategy such as processes and procedures to reduce the risk of exposure and infection through building systems operations, biosurveillance capacity, communication form leadership, and stakeholder engagement for optimal response. These findings reflect the effective application of existing knowledge and standards, emerging science, and lessons-learned from current efforts to confront SARS-CoV-2.

RESUMEN

Given the social and economic upheavals caused by the COVID-19 pandemic, political leaders, health officials, and members of the public are eager for solutions. One of the most promising, if they can be successfully developed, is vaccines. While the technological development of such countermeasures is currently underway, a key social gap remains. Past experience in routine and crisis contexts demonstrates that uptake of vaccines is more complicated than simply making the technology available. Vaccine uptake, and especially the widespread acceptance of vaccines, is a social endeavor that requires consideration of human factors. To provide a starting place for this critical component of a future COVID-19 vaccination campaign in the United States, the 23-person Working Group on Readying Populations for COVID-19 Vaccines was formed. One outcome of this group is a synthesis of the major challenges and opportunities associated with a future COVID-19 vaccination campaign and empirically-informed recommendations to advance public understanding of, access to, and acceptance of vaccines that protect against SARS-CoV-2. While not inclusive of all possible steps than could or should be done to facilitate COVID-19 vaccination, the working group believes that the recommendations provided are essential for a successful vaccination program.

RESUMEN

PURPOSE: Explore acceptability of vaccines in development: cancer, Type II diabetes, Alzheimer's disease, Lyme disease, Ebola, and obesity. Research questions: To what extent does acceptability vary by vaccine type? To what extent does acceptability of vaccines in development vary by race and other key demographics? To what extent are general vaccine hesitancy and key demographics associated with acceptability of vaccines in development? DESIGN: Cross-sectional online survey administered through GfK's KnowledgePanel in 2015. Analysis completed in 2020. SUBJECTS: Nationally representative sample of Black and White American adults (n = 1,643). MEASURES: Willingness to accept a novel vaccine was measured on a 4-point Likert scale. Independent variables included demographics (e.g. age, race, gender) and measures of vaccine hesitancy, trust, and the "Three C's" of vaccine confidence, complacency, and convenience. ANALYSIS: Exploratory analysis including descriptive statistics and regression modeling. RESULTS: Acceptability varied from 77% for a cancer vaccine to 55% for an obesity vaccine. White race, male gender, older age, having a chronic health condition, and higher socioeconomic status were associated with higher acceptability. Higher vaccine confidence and lower vaccine hesitancy were predictors for acceptability. CONCLUSION: The success of a vaccine depends on widespread public acceptance. Vaccine hesitancy may hinder acceptance of future vaccines, with significant differences by demographics. Future social science research is necessary to better understand and address vaccine hesitancy.

RESUMEN

BACKGROUND: Though human papillomavirus (HPV) vaccination is a safe and effective method of protecting against associated cancers, uptake rates remain low among adolescents. Few studies have examined how social media use contributes to HPV-related knowledge gaps among parents and caregivers. OBJECTIVE: To investigate the association between social media use and HPV-related awareness and knowledge with a focus on differences by gender and race/ethnicity among a nationally representative sample of adults with children in the household. METHODS: We used data from the Health Information National Trends (HINTS) Survey (2017-2019) (N = 2,720). Multivariate logistic regressions were used to examine the association of social media use on HPV awareness and knowledge outcomes. RESULTS: Compared to non-users, engaging in one, two, three, or four social media behaviors were associated with greater HPV awareness (aOR: 2.09; 95%CI: 1.18-3.70, aOR: 2.49; 95%CI: 1.40-4.42, aOR: 2.64; 95%CI: 1.15-6.05, and aOR: 2.44; 95%CI: 1.11-5.36, respectively). Increased social media use was associated with increased HPV vaccine awareness. Men, African American, Hispanic, and Asian American respondents were less likely to be aware of HPV or HPV vaccine. Social media use was not associated with cancer knowledge. CONCLUSIONS: Increased social media use is associated with an increased awareness of HPV and HPV vaccine for adults with children in the household. Social media-based efforts can be utilized to increase knowledge of the benefits of HPV vaccination as cancer prevention, which may be a precursor to reducing HPV vaccine hesitancy and encouraging uptake to decrease cancer incidence rates among vulnerable populations.

RESUMEN

Objectives. To understand changes in how Facebook pages frame vaccine opposition.Methods. We categorized 204 Facebook pages expressing vaccine opposition, extracting public posts through November 20, 2019. We analyzed posts from October 2009 through October 2019 to examine if pages' content was coalescing.Results. Activity in pages promoting vaccine choice as a civil liberty increased in January 2015, April 2016, and January 2019 (t[76] = 11.33 [P < .001]; t[46] = 7.88 [P < .001]; and t[41] = 17.27 [P < .001], respectively). The 2019 increase was strongest in pages mentioning US states (t[41] = 19.06; P < .001). Discussion about vaccine safety decreased (rs[119] = -0.61; P < .001) while discussion about civil liberties increased (rs[119] = 0.33; Py < .001]). Page categories increasingly resembled one another (civil liberties: rs[119] = -0.50 [P < .001]; alternative medicine: rs[84] = -0.77 [P < .001]; conspiracy theories: rs[119] = -0.46 [P < .001]; morality: rs[106] = -0.65 [P < .001]; safety and efficacy: rs[119] = -0.46 [P < .001]).Conclusions. The "Disneyland" measles outbreak drew vaccine opposition into the political mainstream, followed by promotional campaigns conducted in pages framing vaccine refusal as a civil right. Political mobilization in state-focused pages followed in 2019.Public Health Implications. Policymakers should expect increasing attempts to alter state legislation associated with vaccine exemptions, potentially accompanied by fiercer lobbying from specific celebrities.

RESUMEN

Objectives. To adapt and extend an existing typology of vaccine misinformation to classify the major topics of discussion across the total vaccine discourse on Twitter.Methods. Using 1.8 million vaccine-relevant tweets compiled from 2014 to 2017, we adapted an existing typology to Twitter data, first in a manual content analysis and then using latent Dirichlet allocation (LDA) topic modeling to extract 100 topics from the data set.Results. Manual annotation identified 22% of the data set as antivaccine, of which safety concerns and conspiracies were the most common themes. Seventeen percent of content was identified as provaccine, with roughly equal proportions of vaccine promotion, criticizing antivaccine beliefs, and vaccine safety and effectiveness. Of the 100 LDA topics, 48 contained provaccine sentiment and 28 contained antivaccine sentiment, with 9 containing both.Conclusions. Our updated typology successfully combines manual annotation with machine-learning methods to estimate the distribution of vaccine arguments, with greater detail on the most distinctive topics of discussion. With this information, communication efforts can be developed to better promote vaccines and avoid amplifying antivaccine rhetoric on Twitter.
