Abstract
Childhood cancer survivors have a higher risk of developing cardiomyopathy than members of the general population. Screening echocardiograms can facilitate early detection and treatment of cardiomyopathy. Furthermore, motivational interviewing can increase uptake of cardiac screening. However, such approaches are time- and resource-intensive, which limits their reach to the survivors who need them. We describe how we utilized a user-centered design process to translate an in-person motivational interviewing intervention into an eHealth tool to improve cardiac screening among childhood cancer survivors. We used an iterative, three-phase, user-centered design approach: (i) setting the stage (convening advisory boards and reviewing the original intervention), (ii) content programming and development (writing and programming intervention text and flow), and (iii) intervention testing (research team testing and cognitive interviews.) For cognitive interviews, participants were recruited via institutional participant registries and medical records. Data were analyzed using rapid qualitative analysis. During Phase 1, we identified survivor and provider advisors and outlined elements of the in-person intervention to change for the eHealth tool. During Phases 2 and 3, advisors recommended several modifications that guided the final intervention content and flow. Examples include: acknowledging potential hesitation or apprehension surrounding medical screenings, addressing barriers and facilitators to obtaining screening, and improving the tool's usability and appeal. In Phase 3, cognitive interview participants suggested additional refinements to the intervention language. This translation process shows that continued in-depth engagement of community advisors and iterative testing can improve the applicability of an eHealth to survivors' lived experiences and social contexts.

Crucial factors for implementing treatment strategies in intractable atonic postpartum haemorrhage: early phase contrast medium extravasation on dynamic CT. Clin Radiol 2024; 79:73-79. [PMID: 37926646 DOI: 10.1016/j.crad.2023.10.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 10/01/2023] [Accepted: 10/08/2023] [Indexed: 11/07/2023]
Abstract
AIM To identify the relationship between contrast medium extravasation (CME) on dynamic contrast-enhanced computed tomography (DCT) and clinical information in intractable atonic postpartum haemorrhage (PPH) and its relevance to treatment with uterine artery embolisation (UAE). MATERIALS AND METHODS Of 90 patients who underwent DCT to diagnose PPH, 60 diagnosed with intractable atonic PPH were investigated retrospectively. Maternal background and clinical indicators were analysed to compare the positive and negative factors of early phase CME. Regression analysis was used to investigate the factors associated with CME. The sensitivity, specificity, and positive and negative predictive values of early phase CME for predicting UAE were calculated. Clinical outcomes were compared between the two groups according to the timing of the decision to undergo UAE. RESULTS Of the 60 patients with intractable atonic PPH, 21 underwent UAE, 20 of whom had early phase CME on DCT. Pre-DCT clinical parameters and clinical indices were not significantly different in presence of early phase CME. Early phase CME was associated with UAE performance, with a sensitivity of 95%, specificity of 87%, positive predictive value of 80%, and negative predictive value of 97%. In cases where UAE was performed after conservative management, there was a significant increase in blood loss and transfusion volume. CONCLUSION Early phase CME is not indicated by background factors or clinical findings. UAE is not required when CME cannot be detected in the uterine cavity. If early phase CME is present, UAE should be considered immediately.

Exploring Caregiver Interest in and Preferences for Interventions for Children With Risk of Asthma Exacerbation: Web-Based Survey. JMIR Form Res 2023; 7:e46341. [PMID: 37531188 PMCID: PMC10433025 DOI: 10.2196/46341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 06/14/2023] [Accepted: 06/15/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Maintaining control of asthma symptoms is the cornerstone of asthma treatment guidelines in the United States. However, suboptimal asthma control and asthma exacerbations among young people are common and are associated with many negative outcomes. Interventions to improve asthma control are needed. For such interventions to be successful, it is necessary to understand the types of interventions that are appealing to caregivers of children with different levels of risk of exacerbation. OBJECTIVE This study aimed to evaluate whether caregivers of children with high (vs low) risk of asthma exacerbation show different levels of interest in and preferences for potential intervention programs and delivery methods. METHODS We contracted with Ipsos to administer a web-based survey to caregivers of children with asthma who were residing in the United States. Caregivers (N=394) reported their interest (1=not at all; 3=a lot) in 9 possible intervention programs and 8 possible intervention delivery methods. Caregivers also indicated their preferences by selecting the 3 intervention programs and 3 delivery methods that "most" interested them. Finally, caregivers completed 2 open-ended questions asking what other resources might be useful for managing their children's asthma. We classified children as having a high risk of exacerbation if they had an exacerbation in the past 3 months (n=116) and a low risk of exacerbation if otherwise (n=278). RESULTS Caregivers reported higher levels of interest in all intervention programs and delivery methods if they cared for a child with a high risk rather than a low risk of exacerbation. However, regardless of the child's risk status, caregivers expressed the highest levels of interest in programs to increase their child's self-management skills, to help pay for asthma care, and to work with the school to manage asthma. Caregivers expressed the highest levels of interest in delivery methods that maintained personal control over accessing information (websites, videos, printed materials, and smartphone apps). Caregivers' preferences were consistent with their interests; programs and delivery methods that were rated as high in interest were also selected as one of the 3 that "most" interested them. Although most caregivers did not provide additional suggestions for the open-ended questions, a few caregivers suggested intervention programs and delivery methods that we had not included (eg, education about avoiding triggers and medication reminders). CONCLUSIONS Similar interests and preferences among caregivers of children with high and low risk of exacerbation suggest a broad need for support in managing childhood asthma. Providers could help caregivers by directing them toward resources that make asthma care more affordable and by helping their children with asthma self-management. Interventions that accommodate caregivers' concerns about having personal control over access to asthma information are likely to be more successful than interventions that do not.

Abstract
INTRODUCTION The spectrum of bladder health and the factors that promote bladder health and prevent lower urinary tract symptoms (LUTS) among women are not well understood. This manuscript describes the rationale, aims, study design, sampling strategy, and data collection for the RISE FOR HEALTH (RISE) study, a novel study of bladder health in women conducted by the Prevention of Lower Urinary Tract Symptom (PLUS) Research Consortium. METHODS AND RESULTS RISE is a population-based, multicenter, prospective longitudinal cohort study of community-dwelling, English- and Spanish-speaking adult women based in the United States. Its goal is to inform the distribution of bladder health and the individual factors (biologic, behavioral, and psychosocial) and multilevel factors (interpersonal, institutional, community, and societal) that promote bladder health and/or prevent LUTS in women across the life course. Key study development activities included the: (1) development of a conceptual framework and philosophy to guide subsequent activities, (2) creation of a study design and sampling strategy, prioritizing diversity, equity, and inclusion, and (3) selection and development of data collection components. Community members and cross-cultural experts shaped and ensured the appropriateness of all study procedures and materials. RISE participants will be selected by simple random sampling of individuals identified by a marketing database who reside in the 50 counties surrounding nine PLUS clinical research centers. Participants will complete self-administered surveys at baseline (mailed paper or electronic) to capture bladder health and LUTS, knowledge about bladder health, and factors hypothesized to promote bladder health and prevent LUTS. A subset of participants will complete an in-person assessment to augment data with objective measures including urogenital microbiome specimens. Initial longitudinal follow-up is planned at 1 year. DISCUSSION Findings from RISE will begin to build the necessary evidence base to support much-needed, new bladder health promotion and LUTS prevention interventions in women.

Abstract
BACKGROUND The promise of precision medicine could be stymied if people do not accept the legitimacy of personalized risk information. We tested 4 explanations for skepticism of personalized diabetes risk information. METHOD We recruited participants (N = 356; Mage = 48.6 [s = 9.8], 85.1% women, 59.0% non-Hispanic white) from community locations (e.g., barbershops, churches) for a risk communication intervention. Participants received personalized information about their risk of developing diabetes and heart disease, stroke, colon cancer, and/or breast cancer (women). Then they completed survey items. We combined 2 items (recalled risk, perceived risk) to create a trichotomous risk skepticism variable (acceptance, overestimation, underestimation). Additional items assessed possible explanations for risk skepticism: 1) information evaluation skills (education, graph literacy, numeracy), 2) motivated reasoning (negative affect toward the information, spontaneous self-affirmation, information avoidance); 3) Bayesian updating (surprise), and 4) personal relevance (racial/ethnic identity). We used multinomial logistic regression for data analysis. RESULTS Of the participants, 18% believed that their diabetes risk was lower than the information provided, 40% believed their risk was higher, and 42% accepted the information. Information evaluation skills were not supported as a risk skepticism explanation. Motivated reasoning received some support; higher diabetes risk and more negative affect toward the information were associated with risk underestimation, but spontaneous self-affirmation and information avoidance were not moderators. For Bayesian updating, more surprise was associated with overestimation. For personal relevance, belonging to a marginalized racial/ethnic group was associated with underestimation. CONCLUSION There are likely multiple cognitive, affective, and motivational explanations for risk skepticism. Understanding these explanations and developing interventions that address them will increase the effectiveness of precision medicine and facilitate its widespread implementation.

Adapting a Research and Community Capacity-Building Program to Address Rural Cancer Burden and Facilitate Partnership Development Between Rural Community Stakeholders and an Urban Comprehensive Cancer Center. JOURNAL OF CANCER EDUCATION : THE OFFICIAL JOURNAL OF THE AMERICAN ASSOCIATION FOR CANCER EDUCATION 2023:10.1007/s13187-022-02256-7.

Abstract
While rural-urban cancer disparities persist, the research building capacity between rural communities and high-quality cancer centers remains limited. Thus, we describe how a National Cancer Institute-designated cancer center partnered with rural community stakeholders to adapt a cancer prevention-focused research and community capacity-building workshop. The workshop's goal was to strengthen community-academic partnerships and facilitate the development of sustainable well-resourced rural cancer-focused research. Researchers from the Siteman Cancer Center partnered with community leaders from rural counties in southern Illinois. We adapted the workshop from an existing evidence-based program. We analyzed changes in knowledge and research capacity and relevance to their community work. From February to May 2019, community partners guided all elements of the workshop development. Workshop participants were mostly White race (93%), had a college degree or beyond (75%), reported living in a rural community (93%), and represented an academic, faith-based, or healthcare institution (78%). Participants' mean knowledge scores of the presented content increased significantly after each session, from 9.3 to 9.9 for session 1 (p = 0.05) and 6.8 to 9.7 (p < 0.001) for session two. Through the workshop, participant scores also increased in research capacity skills, confidence, and their understanding of conducting research in the community. The workshop, co-curated and led by rural community leaders and researchers from Siteman Cancer Center, successfully increased knowledge of and interest in building cancer research capacity. Lessons from our work can inform the implementation of similar programs that address rural cancer health through research and community capacity building between rural community partners and urban cancer centers.

Abstract
Rural residents in underserved areas face many barriers to health services, including colonoscopies for colorectal cancer (CRC) screening, but rural healthcare providers may assist patients navigating these challenges due to familiarity with local contexts. In 2017 to 2018, we interviewed clinical practitioners and staff (n = 40) at 13 primary care and gastroenterology locations across rural Southern Illinois. We used a semi-structured interview guide that addressed system, provider, and patient levels including domains related to barriers, facilitators, and needs for intervention. This article focuses on 3 main elements related to distance and transportation that emerged from inductive coding. First, providers described long distance travel for care as normalized but not necessarily preferable. Second, they identified and described distance-related challenges specific to CRC screening, and third, providers discussed strategies, mostly related to transportation, they use to navigate those challenges. Finally, they suggested a variety of broader solutions to reduce distance and transportation barriers to screening. Overall, distance to care remains a challenge to increasing CRC screening and contributes to disparities in rural communities. To increase early detection and reduce rural cancer disparities, efforts to increase screening and follow-up must address ways to help patients and providers navigate this distance within their local communities and contexts.

Inclusive Recruitment Strategies to Maximize Sociodemographic Diversity among Participants: A St. Louis Case Study. MDM Policy Pract 2023; 8:23814683231183646. [PMID: 37440792 PMCID: PMC10334001 DOI: 10.1177/23814683231183646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 05/19/2023] [Indexed: 07/15/2023] Open
Abstract
Background. Sociodemographically diverse study samples are critical for research related to health decision making. However, not all researchers have the training, capacity, and funding to engage research methods that recruit the most diverse populations. Objective and Methods. We used participant-generated data, staff salary data, and participant observation to examine the effectiveness and cost of strategies that we used for screening, enrolling, and retaining a sociodemographically diverse sample for a risk communication and behavior change randomized controlled trial. Results. It took approximately 646 hours to contact 1,626 individuals and enroll 554 participants (505 of whom completed the baseline survey; 45.2% were members of a underrepresented racial/ethnic group, 19.4% had no college education, 49.5% were age 30-49 y). Retention at 90-d follow-up was 93%. The total cost was USD$19,898.50. The average cost was $35.92 per participant enrolled. In-person recruitment was most successful in identifying the largest proportion of screened and eligible participants who were members of underrepresented racial/ethnic populations (32.8% and 27.8%, respectively) and with no college experience (39.7% and 33.5%, respectively); it also had the highest total cost ($8,079.17). Existing research pools identified the largest proportion of younger participants (ages 30-49 y; 39.3% and 43.4% for screened and eligible, respectively). Existing listservs yielded the smallest proportion of individuals with no college experience and the fewest members of underrepresented racial/ethnic populations but had the lowest total cost ($290.33). Newspaper ads identified the fewest younger individuals and also had the highest cost per participant enrolled ($166.21). Word of mouth had the lowest cost per participant enrolled ($10.47). Conclusion. Results help medical decision-making researchers formulate recruitment plans that increase sociodemographic diversity in study samples. We also ask funders to accommodate increased costs required to maximize sociodemographic diversity in medical decision-making research. Highlights We provide concrete strategies for recruiting, enrolling, and retaining a sociodemographically diverse study sample.We offer cost estimates for all stages of study recruitment and found that in-person recruitment was the most effective, but also the most expensive, way to identify Black participants and participants with no college experience.It is critical for investigators to have access to institutional infrastructure and resources to support conducting research that is inclusive of diverse sociodemographic groups.An intentionally diverse recruitment staff supports a diverse study sample.

Abstract
INTRODUCTION Community engagement is increasingly recognized as a critical component of research, but few studies provide details on how to successfully incorporate community perspectives in urological research. This manuscript describes the community engagement strategy used by the Prevention of Lower Urinary Tract Symptoms Research Consortium (PLUS) to design RISE FOR HEALTH (RISE), a multicenter, population-based, prospective cohort study to promote bladder health. METHODS AND RESULTS The PLUS Community Engagement Subcommittee, guided by a set of antiracist community engagement principles and practices, organized, implemented, and communicated findings for all RISE community engagement activities. Community engagement was conducted through a diverse network of community partners at PLUS clinical research centers called Rapid Assessment Partners (RAPs). Via online surveys (4), virtual discussion groups (14), and one-on-one interviews (12), RAPs provided input on RISE processes and materials, including in-person visit procedures, specimen collection instructions, survey data collection instruments, recruitment materials, the study website, and the study name. This process resulted in significant changes to these aspects of the study design with reciprocal benefits for the community partners. DISCUSSION Meaningful community engagement improved the design and implementation of RISE. PLUS will continue to engage community partners to interpret the RISE study results, disseminate RISE findings, and inform other PLUS studies toward the development of interventions to promote bladder health. Future urological studies would also benefit from community participation in determining priority research questions to address.

Interpersonal comparison among caregivers of children with asthma. Psychol Health 2022:1-20. [PMID: 36147010 PMCID: PMC10030381 DOI: 10.1080/08870446.2022.2125514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 09/11/2022] [Accepted: 09/12/2022] [Indexed: 10/14/2022]
Abstract
Objective: We examined the extent to which caregivers of children with asthma used interpersonal comparisons-a novel comparison process that parallels social comparison and temporal comparison-to form judgments about their child. Methods & Measures: Using semi-structured interviews adapted from the McGill Illness Narrative Interview, we examined the interpersonal comparisons that caregivers of a child with asthma (n = 41) made regarding their child. Results: Interpersonal comparisons influenced caregiver thoughts, feelings, and behavior. They helped caregivers distinguish asthma from other breathing problems, evaluate the severity of the asthma, and understand their child's experience. However, they also created uncertainty by highlighting the complex, unpredictable nature of asthma. Interpersonal comparisons were a source of gratitude and hope, but also worry and frustration. Finally, interpersonal comparisons influenced caregivers' decisions and actions, resulting in decisions that aligned with and, at times, ran counter to biomedical models of asthma care. In some instances, caregivers used interpersonal comparisons to motivate their child's behavior. Conclusion: The interpersonal comparisons served as a source of information for caregivers trying to understand and manage their child's asthma. Investigating these comparisons also expands how we think about other comparison theories.

Abstract
Observations by several cameras on the Perseverance rover showed a 22° scattering halo around the Sun over several hours during northern midsummer (solar longitude 142°). Such a halo has not previously been seen beyond Earth. The halo occurred during the aphelion cloud belt season and the cloudiest time yet observed from the Perseverance site. The halo required crystalline water-ice cloud particles in the form of hexagonal columns large enough for refraction to be significant, at least 11 μm in diameter and length. From a possible 40-50 km altitude, and over the 3.3 hr duration of the halo, particles could have fallen 3-12 km, causing downward transport of water and dust. Halo-forming clouds are likely rare due to the high supersaturation of water that is required but may be more common in northern subtropical regions during northern midsummer.

Abstract
Background Motivational interviewing (MI) can increase health-promoting behaviors and decrease health-damaging behaviors. However, MI is often resource intensive, precluding its use with people with limited financial or time resources. Mobile health–based versions of MI interventions or technology-delivered adaptations of MI (TAMIs) might increase reach. Objective We aimed to understand the characteristics of existing TAMIs. We were particularly interested in the inclusion of people from marginalized sociodemographic groups, whether the TAMI addressed sociocontextual factors, and how behavioral and health outcomes were reported. Methods We employed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews to conduct our scoping review. We searched PubMed, CINAHL, and PsycInfo from January 1, 1996, to April 6, 2022, to identify studies that described interventions incorporating MI into a mobile or electronic health platform. For inclusion, the study was required to (1) describe methods/outcomes of an MI intervention, (2) feature an intervention delivered automatically via a mobile or electronic health platform, and (3) report a behavioral or health outcome. The exclusion criteria were (1) publication in a language other than English and (2) description of only in-person intervention delivery (ie, no TAMI). We charted results using Excel (Microsoft Corp). Results Thirty-four studies reported the use of TAMIs. Sample sizes ranged from 10 to 2069 participants aged 13 to 70 years. Most studies (n=27) directed interventions toward individuals engaging in behaviors that increased chronic disease risk. Most studies (n=22) oversampled individuals from marginalized sociodemographic groups, but few (n=3) were designed specifically with marginalized groups in mind. TAMIs used text messaging (n=8), web-based intervention (n=22), app + text messaging (n=1), and web-based intervention + text messaging (n=3) as delivery platforms. Of the 34 studies, 30 (88%) were randomized controlled trials reporting behavioral and health-related outcomes, 23 of which reported statistically significant improvements in targeted behaviors with TAMI use. TAMIs improved targeted health behaviors in the remaining 4 studies. Moreover, 11 (32%) studies assessed TAMI feasibility, acceptability, or satisfaction, and all rated TAMIs highly in this regard. Among 20 studies with a disproportionately high number of people from marginalized racial or ethnic groups compared with the general US population, 16 (80%) reported increased engagement in health behaviors or better health outcomes. However, no TAMIs included elements that addressed sociocontextual influences on behavior or health outcomes. Conclusions Our findings suggest that TAMIs may improve some health promotion and disease management behaviors. However, few TAMIs were designed specifically for people from marginalized sociodemographic groups, and none included elements to help address sociocontextual challenges. Research is needed to determine how TAMIs affect individual health outcomes and how to incorporate elements that address sociocontextual factors, and to identify the best practices for implementing TAMIs into clinical practice.

Towards emplaced understandings of risk: How caregivers of children with asthma identify and manage asthma-related risk across different places. Health Place 2022; 75:102787.

Abstract
In the United States, pediatric asthma is distributed geographically across lines of racialized segregation. We draw on emplacement, or the theory that embodied experiences and the material world are mutually informed, to situate such geographic trends within the narratives of 41 caregivers of children with asthma. Results suggest that caregivers identified and managed asthma-related risk with regard to the relational and structural conditions of three categories of locations: (1) houses, (2) neighborhoods, and (3) schools and other childhood institutions. Within each type of location, caregivers used emplaced knowledge and emplaced caregiving tactics to respond to asthma-related risk. Based on our findings, we identify critical intervention topics that are consistent with families' everyday lived experiences of place.

RATIONALE Many studies propose that patients', caregivers', and children's asthma management practices may diverge from biomedical recommendations because their understandings of asthma (i.e., conceptual models) are different from biomedical perspectives. However, little research in this area has examined conceptual models of asthma using embodiment theory, which suggests that caregivers' and children's experiences of the physical body shape their perspectives and consequent management strategies. OBJECTIVE We investigated how two embodied processes of symptom perception-detection and interpretation-may influence caregiver or patient conceptions of asthma. METHODS We interviewed 41 caregivers of children with asthma in Gainesville, Florida, and St. Louis, Missouri, and conducted ethnographic visits or virtual interviews with 19 children with asthma aged 6-16. RESULTS Four aspects of asthma's embodied experience shaped conceptual models via processes of detection and interpretation: 1) symptoms are experienced in the context of other bodily processes; 2) acute symptoms and exacerbations are more salient than their absence; 3) the embodied experience of asthma is one of integrated physiological and emotional processes; and 4) caregivers and children acquire embodied practices of perceiving symptoms that produce embodied knowledge. CONCLUSION Participant narratives suggest that embodied experiences of asthma shape caregivers' and children's understandings of asthma in ways that differ from the biomedical model. We argue that a focus on embodied experiences may provide important ground for mutual understanding and communication between providers and caregivers and/or patients.

Mental imagery-based self-regulation: Effects on physical activity behaviour and its cognitive and affective precursors over time. Br J Health Psychol 2021; 27:484-500. [PMID: 34523193 PMCID: PMC8918432 DOI: 10.1111/bjhp.12558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 08/24/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES (1) Test whether a mental imagery-based self-regulation intervention increases physical activity behaviour over 90 days; (2) Examine cognitive and affective precursors of change in physical activity behaviour. DESIGN A randomized control trial with participants (N = 500) randomized to one of six intervention conditions in a 3 (risk communication format: bulleted list, table, risk ladder) x 2 (mental imagery behaviour: physical activity, active control [sleep hygiene]) factorial design. METHODS After receiving personalized risk estimates via a website on a smartphone, participants listened to an audiorecording that guided them through a mental imagery activity related to improving physical activity (intervention group) or sleep hygiene behaviour (active control). Participants received text message reminders to complete the imagery for 3 weeks post-intervention, 4 weekly text surveys to assess behaviour and its cognitive and affective precursors, and a mailed survey 90 days post-baseline. RESULTS Physical activity increased over 90 days by 19.5 more minutes per week (95%CI: 2.0, 37.1) in the physical activity than the active control condition. This effect was driven by participants in the risk ladder condition, who exercised 54.8 more minutes (95%CI 15.6, 94.0) in the physical activity condition than participants in the active control sleep hygiene group. Goal planning positively predicted physical activity behaviour (b = 12.2 minutes per week, p = 0.002), but self-efficacy, image clarity, and affective attitudes towards behaviours did not (p > 0.05). CONCLUSIONS Mental imagery-based self-regulation interventions can increase physical activity behaviour, particularly when supported by personalized disease risk information presented in an easy-to-understand format.

Abstract
BACKGROUND Personalized medicine may increase the amount of probabilistic information patients encounter. Little guidance exists about communicating risk for multiple diseases simultaneously or about communicating how changes in risk factors affect risk (hereafter "risk reduction"). PURPOSE To determine how to communicate personalized risk and risk reduction information for up to 5 diseases associated with insufficient physical activity in a way laypeople can understand and that increases intentions. METHODS We recruited 500 participants with <150 min weekly of physical activity from community settings. Participants completed risk assessments for diabetes, heart disease, stroke, colon cancer, and breast cancer (women only) on a smartphone. Then, they were randomly assigned to view personalized risk and risk reduction information organized as a bulleted list, a simplified table, or a specialized vertical bar graph ("risk ladder"). Last, they completed a questionnaire assessing outcomes. Personalized risk and risk reduction information was presented as categories (e.g., "very low"). Our analytic sample (N = 372) included 41.3% individuals from underrepresented racial/ethnic backgrounds, 15.9% with vocational-technical training or less, 84.7% women, 43.8% aged 50 to 64 y, and 71.8% who were overweight/obese. RESULTS Analyses of covariance with post hoc comparisons showed that the risk ladder elicited higher gist comprehension than the bulleted list (P = 0.01). There were no significant main effects on verbatim comprehension or physical activity intentions and no moderation by sex, race/ethnicity, education, numeracy, or graph literacy (P > 0.05). Sequential mediation analyses revealed a small beneficial indirect effect of risk ladder versus list on intentions through gist comprehension and then through perceived risk (bIndirectEffect = 0.02, 95% confidence interval: 0.00, 0.04). CONCLUSION Risk ladders can communicate the gist meaning of multiple pieces of risk information to individuals from many sociodemographic backgrounds and with varying levels of facility with numbers and graphs.

Abstract
BACKGROUND Structural determinants of health are social, economic, and environmental forces that generate unequal opportunities for resources and unequally distribute exposure to risk. For example, economic constraint, racial discrimination and segregation, and environmental injustice shape population-level asthma prevalence and severity. Structural determinants are especially relevant to consider in clinical settings because they affect everyday household asthma management. OBJECTIVE To examine how structural determinants shape everyday household management of pediatric asthma and offer a framework for providers to understand asthma management in social context. DESIGN Qualitative interviews of caregivers for children with asthma. PARTICIPANTS Participants included 41 caregivers in two U.S. cities: St. Louis, Missouri (n = 25) and Gainesville, Florida (n = 16). Most caregivers were women (83%), Black (73%) and/or had low socioeconomic status (SES; 78%). Caregivers cared for children with asthma aged 0-4 (32%), 5-11 (68%) and 12-17 (54%). APPROACH We carried out narrative interviews with caregivers using an adapted McGill Illness Narrative Interview and using qualitative analysis techniques (e.g. inductive and deductive coding, constant comparison). KEY RESULTS Caregivers highlighted three ways that structural determinants complicated asthma management at home: 1) housing situations, 2) competing household illnesses and issues, and 3) multi-household care. CONCLUSIONS By connecting social, economic, and environmental injustices to the everyday circumstances of asthma management, our study can help providers understand how social contexts challenge asthma management and can open conversations about barriers to adherence and strategies for supporting asthma management at home. We offer recommendations for medical system reform, clinical interactions, and policy advocacy.

Location and Setting of the Mars InSight Lander, Instruments, and Landing Site. EARTH AND SPACE SCIENCE (HOBOKEN, N.J.) 2020; 7:e2020EA001248.

Abstract
Knowing precisely where a spacecraft lands on Mars is important for understanding the regional and local context, setting, and the offset between the inertial and cartographic frames. For the InSight spacecraft, the payload of geophysical and environmental sensors also particularly benefits from knowing exactly where the instruments are located. A ~30 cm/pixel image acquired from orbit after landing clearly resolves the lander and the large circular solar panels. This image was carefully georeferenced to a hierarchically generated and coregistered set of decreasing resolution orthoimages and digital elevation models to the established positive east, planetocentric coordinate system. The lander is located at 4.502384°N, 135.623447°E at an elevation of -2,613.426 m with respect to the geoid in Elysium Planitia. Instrument locations (and the magnetometer orientation) are derived by transforming from Instrument Deployment Arm, spacecraft mechanical, and site frames into the cartographic frame. A viewshed created from 1.5 m above the lander and the high-resolution orbital digital elevation model shows the lander is on a shallow regional slope down to the east that reveals crater rims on the east horizon ~400 m and 2.4 km away. A slope up to the north limits the horizon to about 50 m away where three rocks and an eolian bedform are visible on the rim of a degraded crater rim. Azimuths to rocks and craters identified in both surface panoramas and high-resolution orbital images reveal that north in the site frame and the cartographic frame are the same (within 1°).

Abstract
Abstract
Introduction: The relative dearth of financial and human resources in rural areas complicates the delivery of timely medical expertise and treatment to its inhabitants. Travel distances between patients and their providers pose transportation barriers that contribute to low colorectal cancer screening rates in rural areas. Increasing applications of telemedicine technologies in health care may reduce or mitigate problems associated with transportation and insufficient availability of local providers. The objective of this study was to conduct a scoping review to compare types of telemedicine interventions for colorectal cancer screening in rural areas to those that have been studied more broadly, evaluate the quality of existing evidence, and suggest opportune areas for further investigation and application.
Methods: Searches were conducted in Ovid Medline, EMBASE, and Cochrane databases with the guidance of a librarian. We included peer-reviewed full text articles in English and Spanish about telemedicine interventions in CRC screening. Telemedicine interventions for CRC screening were operationally defined as the use of telephone and Internet-based technologies to aid patient decision making, reduce transportation barriers, and circumvent lack of local human resources from the first moment of screening awareness through cancer diagnosis. We did not exclude articles based on study design type. Risk of bias was assessed through measures including randomization, blinding, and incomplete outcome reporting. Quality was defined by factors such as risk of bias and representativeness of sampled populations.
Results: Of 2223 non-duplicate studies, 167 articles fell into the following intervention categories: feasibility and logistics, decision aids, reminders, motivational interviewing, and remote expert evaluation. Reminders were the most robust area of the literature, with more RCTs and large-scale studies conducted. Many studies compared the efficacy of automated screening reminders with those performed by staff. Common outcomes that were measured in all categories except remote expert evaluation were patient acceptability and CRC screening completion within designated time frames. Articles about decision aids exhibited heterogeneity of dissemination method and types of informational materials included. Studies on remote expert evaluation were variable in scope and reported results for interobserver reliability and sensitivity. Of the studies included, nine took place or were targeted for application in rural or remote areas. Of those nine studies, five were about reminders, reflecting trends in the wider literature.
Discussion: Given the paucity of CRC screening interventions that were studied in rural areas, further investigation is needed to determine whether broadly studied telemedicine interventions are applicable, particularly since underserved populations in rural areas stand to benefit disproportionately from evidence-based telemedicine interventions.

Abstract
Abstract
Introduction: Despite the widespread availability of preventative tests and procedures, colorectal cancer (CRC) remains one of the leading causes of cancer deaths in the United States. While national CRC screening rates have increased, they have languished in rural areas. Routine screening is most effective in reducing CRC mortality when accompanied by timely diagnostic follow-up, but transportation barriers are a hindrance to continuity of care. Distances between homes and providers exacerbate the problem in rural areas. We examined reported transportation barriers in seven counties at both patient and clinic levels as part of a collaborative endeavor with a rural health system in Southern Illinois to characterize current conditions and design multilevel interventions to increase screening and follow-up in rural populations.
Methods: Semistructured interviews and focus groups were conducted with six patients and forty providers across eleven primary care sites and two colonoscopy providers. Interview domains included screening barriers and facilitators. Interview transcripts and field notes underwent text analysis with inductive codes. Themes such as financial resources, transport reliability, and time constraints were used to create subcategories and refine analysis. Transportation was discussed at multiple levels of influence in screening decisions, planning, and completion. Here we present a detailed analysis of how distance and transportation were discussed.
Results: Limited regional provider availability dictates that medical visits require long travel times for many patients. Patients described travel distance and discomfort during transit to colonoscopies as obstacles. Those who had an easier time arranging transportation relied on social support, but encountered issues coordinating time off work. Staff had varying knowledge of available transportation and clinics had different levels of resources to support patients. Travel assistance included referral to transport services, public transport vouchers, and reimbursement. Some clinics did not offer travel assistance, or only provided help in cases of urgent medical need. Outsourced transport service reliability was variable and often required advance notice, which affected colonoscopy scheduling. Some sites that offered transport assistance cited poor communication among clinic staff and role specialization as reasons that patient needs were not met.
Discussion: Patient need communication and provider and staff education regarding community transportation present opportunities to reduce transportation barriers. Evidence-based interventions such as dedicated non-emergency medical transport services are needed to address reliability, infrastructure needs, and the hardships of taking time off work for appointments. In designing multilevel interventions, researchers must consider differences in financial and human resources across sites and limited staff and patient time.

Abstract
PURPOSE Rural health networks have the potential to improve health care quality and access. Despite this, the use of network analysis to study rural health networks is limited. The purpose of this study was to use network analysis to understand how a network of rural breast cancer care providers deliver services and to demonstrate the value of this methodology in this research area. METHODS Leaders at 47 Federally Qualified Health Centers and Rural Health Clinics across 10 adjacent rural counties were asked where they refer patients for mammograms or breast biopsies. These clinics and the 22 referral providers that respondents named comprised the network. The network was analyzed graphically and statistically with exponential random graph modeling. FINDINGS Most (96%, n = 45) of the clinics and referral sites (95%, n = 21) are connected to each other. Two clinics of the same type were 62% less likely to refer patients to the same providers as 2 clinics of different types (OR = 0.38, 95% CI = 0.29-0.50). Clinics in the same county have approximately 8 times higher odds of referring patients to the same providers compared to clinics in different counties (OR = 7.80, CI = 4.57-13.31). CONCLUSIONS This study found that geographic location of resources is an important factor in rural health care providers' referral decisions and demonstrated the usefulness of network analysis for understanding rural health networks. These results can be used to guide delivery of patient care and strengthen the network by building resources that take location into account.

Abstract
Controlling rabies in skunk populations is an important public health concern in many parts of the United States due to the potential for skunk rabies outbreaks in urban centres and the possible role for skunks in raccoon rabies variant circulation. Oral rabies vaccination (ORV) programmes have supported wildlife rabies control efforts globally but using ORV to control rabies in skunk populations has proven more challenging than with other target species, like foxes, coyotes and raccoons. A review of published studies found that some ORV constructs are immunogenic in skunks and protect against virulent rabies virus challenges, especially when delivered by direct installation into the oral cavity. However, in field ORV programmes using currently available vaccine-bait formats and distribution methods targeting other rabies reservoir species, skunks often fail to seroconvert. Field effectiveness of ORV in skunks appears to be limited by poor bait uptake or inadequate ingestion of vaccine rather than from poor vaccine efficacy. Observations of captive skunks revealed vaccine spillage when handling and biting into baits such that modification of bait formats might improve field effectiveness. In addition, a dose-response relationship between bait distribution density and post-baiting seroconversion among skunks was observed across the limited number of field studies. Additional research is needed to identify opportunities to modify ORV baits and distribution strategies to improve the viability of ORV as a rabies control strategy in skunks.

Abstract
BACKGROUND While there is convincing evidence on interventions to improve bowel preparation for patients, the evidence on how to implement these evidence-based practices (EBPs) in outpatient colonoscopy settings is less certain. The Strategies to Improve Colonoscopy (STIC) study compares the effect of two implementation strategies, physician education alone versus physician education plus an implementation toolkit for staff, on adoption of three EBPs (split-dosing of bowel preparation, low-literacy education, teach-back) to improve pre-procedure and intra-procedure quality measures. The implementation toolkit contains a staff education module, website containing tools to support staff in delivering EBPs, tailored patient education materials, and brief consultation with staff to determine how the EBPs can be integrated into the existing workflow. Given adaptations to the implementation plan and intentional flexibility in the delivery of the EBPs, we utilize a pragmatic study to balance external validity with demonstrating effectiveness of the implementation strategies. METHODS/DESIGN Participants will include all outpatient colonoscopy physicians, staff, and patients from a convenience sample of six endoscopy settings. Aim #1 will explore the relative effect of two strategies to implement patient-level EBPs on adoption and clinical quality outcomes. We will assess the change in level and trends of clinical quality outcomes (i.e., adequacy of bowel preparation, adenoma detection) using segmented regression analysis of interrupted time series data with two groups (intervention and delayed start). Aim #2 will examine the influence of organizational readiness to change on EBP implementation. We use a PRECIS diagram to reflect the extent to which each indicator of the study was pragmatic versus explanatory, revealing a largely pragmatic study. DISCUSSION Implementation challenges have already motivated several adaptations to the original plan, reflecting the nature of implementation in real-world healthcare settings. The pragmatic study responds to the evolving needs of its healthcare partners and allows for flexibility in intervention delivery, thereby informing clinical decision-making in real-world settings. The current study will provide information about what works (intervention effectiveness), for whom it works (influence of Medicaid versus other insurance), in which contexts it works (setting characteristics that influence implementation), and how it works best (comparison of implementation strategies).

Abstract
Additional Middle Paleolithic human remains from layers 17, 18, and 22 of the Gruta da Oliveira, Portugal consist of a proximal manual phalanx 2 (Oliveira 5), a partial postcanine tooth (Oliveira 6), a humeral diaphysis (Oliveira 7), a distal mandibular molar (Oliveira 8), and a mandibular premolar (P(3) ) (Oliveira 9). Oliveira 5, 6, and 8 are unremarkable for Late Pleistocene humans. The Oliveira 7 right humerus is moderately robust or the individual had the stocky body proportions of other European (including Iberian) Neandertals. The Oliveira 9 P(3) has a large and symmetrical crown and lacks a distal accessory ridge and accessory lingual cusps, overlapping both Neandertal and recent human ranges of variation. It contrasts with at least recent human P(3) s in having relatively thin enamel. These join the Oliveira 1 to 4 remains in further documenting early MIS 3 Neandertal morphology in western Iberia.

Abstract
BACKGROUND The use of mitochondrial DNA (mtDNA) damage as a reliable and highly sensitive biomarker of ultraviolet (UV) radiation exposure in both the dermis and epidermis has now been well developed by our group and others. We have previously identified a 3895-bp mtDNA deletion which occurred more frequently and to a higher level in usually sun-exposed skin as opposed to occasionally sun-exposed skin. This work focused on older-aged individuals and, in particular, perilesional, histologically normal skin biopsies taken from patients with skin cancer. OBJECTIVES To develop novel, less-invasive methods of obtaining skin samples (i.e. epidermis) from volunteers covering a much wider age range and larger number of individuals (n = 239). METHODS The 3895-bp deletion was quantified by a specific real-time polymerase chain reaction assay in normal human epidermis samples taken from three body sites with differing sun exposure. RESULTS The results show a statistical increase of the level of the 3895-bp deletion with increasing sun exposure in the epidermal swabs of human skin (P < 0·001) and with increasing age of the donor in the needle biopsy samples. CONCLUSIONS These data suggest that the upper layers of the epidermis are an accessible and reliable site for assessing mtDNA damage caused by UV exposure.

Abstract
Oral vaccination programmes conducted in rabies infected countries from Eastern Europe and Eurasia should not be restricted to foxes but should target other major rabies vectors such as dogs and raccoon dogs as well. The objective of this experimental trial was to assess the protection induced by the vaccine by challenging these different species, which had been previously vaccinated intramuscularly with the square V-RG baits (produced in the US). Different parameters were evaluated such as attractiveness of the baits and induction of neutralising antibodies as an indicator for immunogenicity and protection after rabies challenge. The acceptability of the square bait was satisfactory in dogs, foxes and raccoon dogs, confirming previous laboratory and field studies conducted with the rectangular baits. Only one vaccinated dog out of nine seroconverted after vaccination and among them one dog died of rabies. Eight of ten vaccinated foxes seroconverted after vaccination and survived the rabies challenge. All vaccinated raccoon dogs seroconverted after challenge and all survived the challenge. These trials demonstrated that the square presentation of the V-RG vaccine was attractive, immunogenic and efficacious.

Abstract
AbstractTwelve extracts of 11 Guatemalan medicinal plants were initially screened in vitro for potential macrofilaricidal activity against Brugia pahangi, a lymphatic dwelling filarial worm, using concentrations from 125 to 1000 μg ml−1 of each extract that could be dissolved in the culture medium. Of 12 extracts used, the ethanol extract of leaves of Neurolaena lobata showed the strongest activity against the motility of adult worms. Subsequently, the extract of N. lobata was extensively examined in vitro for macro- and micro-filaricidal effects using a series of concentrations of 500, 250, 100, 50 and 10 μg ml−1. The effects were assessed by worm motility, microfilarial release by female worms and a MTT assay. The effect on the motility of adult worms was observed in a concentration- and time-dependent manner. The time required to stop motility of both sexes of adult worms was 6 h at 500 μg ml−1, 24 h at 250 μg ml−1, and 3 days for females and 4 days for males at 100 μg ml−1. The movement of females ceased at 4 days at a concentration of 50 μg ml−1 whereas the motility of males was only reduced. The loss of worm's viability was confirmed by the MTT assay and was similar to the motility results. These concentrations, including 10 μg ml−1, prevented microfilarial release by females in a concentration- and time-dependent manner. Concentrations higher than 100 μg ml−1 even induced mortality of the microfilariae. The present study suggested that the ethanol extract of Neurolaena lobata has potential macro- and micro-filaricidal activities.

Abstract
Ongoing excavations in the Middle Paleolithic levels at the Gruta da Oliveira, Portugal have yielded four fragmentary human remains, a manual phalanx and an ulna from levels 9 and 10, and a humerus and a tibia from levels 18 and 19. The first two remains date to approximately 39 ka 14C BP ( approximately 43.5 ka cal BP), whereas the latter two derive from earlier in oxygen isotope stage 3. The preserved portions of the phalanx, humerus, and tibia align them morphologically with the Neandertals. In addition, the Oliveira 4 tibial diaphysis shows evidence of carnivore (probably canid) gnawing.

Abstract
People in the Katayama area of Hiroshima Prefecture had been afraid of a curious disease for a long time. The causative agent for the disease had not been identified through the beginning of the 20th century when it turned out that a human parasitic trematode, Schistosoma japonicum, had been afflicting the inhabitants, causing this disease. This was made clear mainly by two medical doctors, Akira Fujinami and Ryuzo Yoshida, much before 1909. The memoir on the disease described by a herb doctor, Yoshinao Fujii (1847), was made known by A. Fujinami to medical scientists in 1909.

Abstract
The preparation, testing and use of a variety of cholesterol-, deoxycorticosterone (DOC)- and pregnenolone-binding 1,6-diaminohexyl (EAH)-Sepharose 4B supports for affinity column chromatography of cytochromes P-450(scc) and P-450(17 alpha) from bovine adrenal and pig testis are described. EAH-Sepharose 4B has free amino groups at the end of a 10-atom spacer arm. Hydroxyl groups of cholesterol (3 beta), deoxycorticosterone (21 beta) and pregnenolone (3 beta) are linked to succinic anhydride in pyridine through an ester linkage. These coupling ligands of hemisuccinate were synthesized by a general procedure. Free amino groups of EAH-Sepharose 4B were used to couple ligands, containing carboxyl groups, by the carbodiimide coupling method. Both the purified cytochromes P-450(scc) and P-450(17 alpha) were found to be homogeneous and estimated to have a molecular weight of 52,000 on polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The carbon monoxide difference spectra with peaks at 450 and 448 nm exhibit the absorption spectra of typical cytochromes P-450(scc) and P-450(17 alpha), respectively. Cytochromes P-450(scc) and P-450(17 alpha) were determined to have isoelectric points of 8.0 and 6.5 in isoelectric focusing on a pH gradient gel. Cytochrome P-450s can be purified between 425- and 1000-fold from the crude extracts.

Abstract
The purification process for cytochrome P450 is very complicated, involving five or more column chromatography steps for the final preparation. This paper describes a reduction in the number of the steps; it can be easily purified from pig testis microsomes with improved the yield. As the first step, DEAE-Toyopearl column chromatography is performed only once and then, as the second step, the partially purified cytochrome P450 is completely purified by a preparative Ampholine PAG-plate Gel for Isoelectric Focusing. The combination reduced the purification to a two-step procedure.

Abstract
Adult testicular cytochrome P-450 was purified by a two-step procedure utilizing hydroxylapatite and deoxycorticosterone affinity column chromatography. Cytochrome P-450 was determined to have an isoelectric point of 6.5 on analytical isoelectric focusing. The purified cytochrome P-450 was found to be homogeneous and its molecular mass was estimated to be 52000 on polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The carbon monoxide difference spectrum with a peak at 448 nm exhibited the absorption spectrum of a typical cytochrome P-450. A 1000-fold purification was achieved with a yield of 5%.
