Structure of the Branched-chain Amino Acid and GTP-sensing Global Regulator, CodY, from Bacillus subtilis.

CodY is a branched-chain amino acid (BCAA) and GTP sensor and a global regulator of transcription in low G + C Gram-positive bacteria. It controls the expression of over 100 genes and operons, principally by repressing during growth genes whose products are required for adaptations to nutrient limitation. However, the mechanism by which BCAA binding regulates transcriptional changes is not clear. It is known that CodY consists of a GAF (cGMP-stimulated phosphodiesterases, adenylate cyclases, FhlA) domain that binds BCAAs and a winged helix-turn-helix (wHTH) domain that binds to DNA, but the way in which these domains interact and the structural basis of the BCAA dependence of this interaction are unknown. To gain new insights, we determined the crystal structure of unliganded CodY from Bacillus subtilis revealing a 10-turn α-helix linking otherwise discrete GAF and wHTH domains. The structure of CodY in complex with isoleucine revealed a reorganized GAF domain. In both complexes CodY was tetrameric. Size exclusion chromatography with multiangle laser light scattering (SEC-MALLS) experiments showed that CodY is a dimer at concentrations found in bacterial cells. Comparison of structures of dimers of unliganded CodY and CodY-Ile derived from the tetramers showed a splaying of the wHTH domains when Ile was bound; splaying is likely to account for the increased affinity of Ile-bound CodY for DNA. Electrophoretic mobility shift and SEC-MALLS analyses of CodY binding to 19-36-bp operator fragments are consistent with isoleucine-dependent binding of two CodY dimers per duplex. The implications of these observations for effector control of CodY activity are discussed.

A mixed-method evaluation of peer-education workshops for school-aged children to teach about antibiotics, microbes and hygiene.

Background: Delivering health topics in schools through peer education is known to be beneficial for all students involved. In this study, we have evaluated a peer-education workshop that aims to educate primary and secondary school students on hygiene, the spread of infection and antibiotics. Methods: Four schools in south-west England, in a range of localities, took part in peer-education workshops, with students completing before, after and knowledge-retention questionnaires. Mixed-effect logistic regression and mixed-effect linear regression were used to analyse the data. Data were analysed by topic, region and peer/non-peer-educator status. Qualitative interviews and focus groups with students and educators were conducted to assess changes in participants' skills, confidence and behaviour. Results: Qualitative data indicated improvements in peer-educator skills and behaviour, including confidence, team-working and communication. There was a significant improvement in knowledge for all topics covered in the intervention, although this varied by region. In the antibiotics topic, peer-educators' knowledge increased in the retention questionnaire, whereas non-peer-educators' knowledge decreased. Knowledge declined in the retention questionnaires for the other topics, although this was mostly not significant. Conclusions: This study indicates that peer education is an effective way to educate young people on important topics around health and hygiene, and to concurrently improve communication skills. Its use should be encouraged across schools to help in the implementation of the National Institute for Health and Care Excellence (NICE) guidance that recommends children are taught in an age-appropriate manner about hygiene and antibiotics.

School Nurses' perspectives on the role of the school nurse in health education and health promotion in England: a qualitative study.

BACKGROUND: The role of the school nurse is complex with many possible elements identified by previous research. The aim of this study is to understand perceptions of the role of the school nurse in order to support school nurses in the delivery of health education. METHODS: The study used an inductive, qualitative research design involving semi-structured interviews and focus groups. Participants were recruited from four NHS trusts across England and final sample size was thirty one school nurses. Three focus groups and two interviews took place in person, and three interviews were over the phone. Data was thematically analysed. RESULTS: School nurses described six main themes. Four themes directly related to the school nurse role: the main roles of a school nurse, school nurses' role in health education, prioritisation of workload and activities, and community work. A further two other themes related to the delivery of health education: the school nursing system and educational resources. CONCLUSIONS: The role of the school nurse in England is very diverse and the school nurse role in health education is primarily to advise and support schools, rather than to directly deliver education. The study identified that tailored public health educational resources are needed to support school nurses.

Practice adaptive reserve and colorectal cancer screening best practices at community health center clinics in 7 states.

BACKGROUND: Enhancing the capability of community health centers to implement best practices (BPs) may mitigate health disparities. This study investigated the association of practice adaptive reserve (PAR) with the implementation of patient-centered medical home (PCMH) colorectal cancer (CRC) screening BPs at community health center clinics in 7 states. METHODS: A convenience sample of clinic staff participated in a self-administered, online survey. Eight PCMH CRC screening BPs were scored as a composite ranging from 0 to 32. The PAR composite score was scaled from 0 to 1 and then categorized into 3 levels. Multilevel analyses examined the relation between PAR and self-reported implementation of PCMH BPs. RESULTS: There were 296 respondents, and 59% reported 6 or more PCMH BPs at their clinics. The mean PAR score was 0.66 (standard deviation, 0.18), and the PCMH BP mean scores were significantly higher for respondents who reported higher clinic PAR categories. In comparison with the lowest PAR level, adjusted PCMH BP means were 25.0% higher at the middle PAR level (difference, 3.2; standard error, 1.3; t = 2.44; P = .015) and 63.2% higher at the highest PAR level (difference, 8.0; standard error, 1.9; t = 4.86; P < .0001). CONCLUSIONS: A higher adaptive reserve, as measured by the PAR score, was positively associated with self-reported implementation of PCMH CRC screening BPs by clinic staff. Future research is needed to determine the PAR levels most conducive to implementing CRC screening and to develop interventions that enhance PAR in primary care settings.

Decreased Cancer Mortality-to-Incidence Ratios with Increased Accessibility of Federally Qualified Health Centers.

Federally qualified health centers (FQHCs) offer primary and preventive healthcare, including cancer screening, for the nation's most vulnerable population. The purpose of this study was to explore the relationship between access to FQHCs and cancer mortality-to-incidence ratios (MIRs). One-way analysis of variance was conducted to compare the mean MIRs for breast, cervical, prostate, and colorectal cancers for each U.S. county for 2006-2010 by access to FQHCs (direct access, in-county FQHC; indirect access, adjacent-county FQHC; no access, no FQHC either in the county or in adjacent counties). ArcMap 10.1 software was used to map cancer MIRs and FQHC access levels. The mean MIRs for breast, cervical, and prostate cancer differed significantly across FQHC access levels (p < 0.05). In urban and healthcare professional shortage areas, mean MIRs decreased as FQHC access increased. A trend of lower breast and prostate cancer MIRs in direct access to FQHCs was found for all racial groups, but this trend was significant for whites only. States with a large proportion of rural and medically underserved areas had high mean MIRs, with correspondingly more direct FQHC access. Expanding FQHCs to more underserved areas and concentrations of disparity populations may have an important role in reducing cancer morbidity and mortality, as well as racial-ethnic disparities, in the United States.

Innovative and community-driven communication practices of the South Carolina cancer prevention and control research network.

The South Carolina Cancer Prevention and Control Research Network (SC-CPCRN) is 1 of 10 networks funded by the Centers for Disease Control and Prevention and the National Cancer Institute (NCI) that works to reduce cancer-related health disparities. In partnership with federally qualified health centers and community stakeholders, the SC-CPCRN uses evidence-based approaches (eg, NCI Research-tested Intervention Programs) to disseminate and implement cancer prevention and control messages, programs, and interventions. We describe the innovative stakeholder- and community-driven communication efforts conducted by the SC-CPCRN to improve overall health and reduce cancer-related health disparities among high-risk and disparate populations in South Carolina. We describe how our communication efforts are aligned with 5 core values recommended for dissemination and implementation science: 1) rigor and relevance, 2) efficiency and speed, 3) collaboration, 4) improved capacity, and 5) cumulative knowledge.

Provider communication and role modeling related to patients' perceptions and use of a federally qualified health center-based farmers' market.

Farmers' markets have the potential to improve the health of underserved communities, shape people's perceptions, values, and behaviors about healthy eating, and serve as a social space for both community members and vendors. This study explored the influence of health care provider communication and role modeling for diabetic patients within the context of a farmers' market located at a federally qualified health center. Although provider communication about diet decreased over time, communication strategies included: providing patients with "prescriptions" and vouchers for market purchases; educating patients about diet; and modeling healthy purchases. Data from patient interviews and provider surveys revealed that patients enjoyed social aspects of the market including interactions with their health care provider, and providers distributed prescriptions and vouchers to patients, shopped at the market, and believed that the market had potential to improve the health of staff and patients of the federally qualified health center. Provider modeling of healthy behaviors may influence patients' food-related perceptions and dietary behaviors.

Assessing readiness for establishing a farmers' market at a community health center.

Farmers' markets are community health promotion interventions that increase access to fresh fruits and vegetables. As farmers' markets continue to develop, it is important to strategically locate them in settings that are accessible to populations disparately affected by health disparities. One potential setting is a community health center. The goal of this analysis is to extend existing research on community readiness to identify indicators of preparedness among community health centers for establishing onsite farmers' markets. The sampling frame for the readiness assessment included all community health centers in South Carolina (N = 20) representing 163 practice sites. Data collection included two brief online surveys, in-depth key informant interviews, and secondary analysis of contextual data. Five themes related to readiness for establishing a farmers market at a community health center were identified: capacity, social capital, awareness of health problems and solutions, logistical factors, and sustainability. Findings from this study provide guidance to researchers and community health center staff as they explore the development of environmental interventions focused on reducing diet-related health conditions by improving access to healthy foods.

Reducing cancer disparities through innovative partnerships: a collaboration of the South Carolina Cancer Prevention and Control Research Network and Federally Qualified Health Centers.

The South Carolina Cancer Prevention and Control Research Network, in partnership with the South Carolina Primary Health Care Association, and Federally Qualified Health Centers (FQHCs), aims to promote evidence-based cancer interventions in community-based primary care settings. Partnership activities include (1) examining FQHCs' readiness and capacity for conducting research, (2) developing a cancer-focused data sharing network, and (3) integrating a farmers' market within an FQHC. These activities identify unique opportunities for public health and primary care collaborations.

Evaluation of an Educational Health Website on Infections and Antibiotics in England: Mixed Methods, User-Centered Approach.

BACKGROUND: e-Bug, an educational health website for teachers and students, aims to help control antibiotic resistance by educating young people about microbes, hygiene, and antibiotic resistance, reducing the incidence of infection and, therefore, the need for antibiotics. The teachers' section of the e-Bug website has not been evaluated since it was launched in 2009, and worldwide page views have been steadily decreasing since 2013. OBJECTIVE: This study aimed to apply GoodWeb, a comprehensive framework utilizing methodologies and attributes that are relevant to the digital era, to evaluate and suggest improvements to the e-Bug website. METHODS: Electronic questionnaires and face-to-face completion of task scenarios were used to assess content, ease of use, interactivity, technical adequacy, appearance, effectiveness, efficiency, and learnability of the teachers' section of the e-Bug website. RESULTS: A total of 106 teachers evaluated the e-Bug website; 97.1% (103/106) of them reported that they would use e-Bug, and 98.1% (104/106) of them reported that they would recommend it to others. Participants thought that there was a niche for e-Bug because of the way the resources fit into the national curriculum. Suggestions for improvements included changing the menu indication by highlighting the current page or deactivating links, improving home page indication, and providing a preview of resources when hovering the mouse over hyperlinks. Additional features requested by users included a search function and access to training opportunities. CONCLUSIONS: This paper reports that the GoodWeb framework was successfully applied to evaluate the e-Bug website, and therefore, it could be used to guide future website evaluations in other fields. Results from this study will be used to appraise the current quality and inform any future changes, modifications, and additions to e-Bug.

International promotion of e-Bug, an infection prevention and control educational intervention: survey of partners across 14 countries.

BACKGROUND: Antimicrobial resistance (AMR) is a global threat to public health. e-Bug is an educational resource developed and promoted by a network of international partners. e-Bug seeks to reduce the spread of infection and use of antimicrobials in young people and the community, so helping to control AMR. This study aimed to explore how e-Bug is promoted by international partners and observe barriers to promotion, including the extent of education about antibiotics in schools. METHODS: A total of 29 e-Bug partners were invited to complete online questionnaires on (i) methods they use to promote e-Bug; and (ii) antibiotic topics covered in the national curriculum in their countries. RESULTS: Fourteen and 15 of 29 e-Bug partners across Europe and Palestine completed the promotional activities and curriculum questionnaires respectively. The most frequently reported methods of promotion included endorsement and collaboration with government and non-government sectors and involvement in national and global health awareness campaigns. Barriers to promotion included a lack of time and funding. The curriculum survey data showed variation in antibiotic education across Europe and Palestine, lack of antibiotic education for children under 11 years of age and little change in antibiotic topics included in the curriculum since 2006. CONCLUSIONS: Future and existing e-Bug partners should be encouraged to follow promotional activities reported in this paper, including ministry endorsement, educator training, international campaigns and youth programmes. We encourage all countries to increase antibiotic topics in the school curriculum across all ages.

Cervical cancer screening behaviors and proximity to federally qualified health centers in South Carolina.

INTRODUCTION: Lack of participation in cervical cancer screening in underserved populations has been attributed to access to care, particularly among women in rural areas. Federally Qualified Health Centers (FQHCs) were created to address this need in medically underserved populations. This study observed proximity to three health centers in relation to cervical cancer screening rates in South Carolina. METHODS: Data were obtained from FQHC patient visits (from 3 centers) between 2007-2010 and were limited to women eligible for cervical cancer screening (n = 24,393). ArcGIS was used to geocode patients addresses and FQHC locations, and distance was calculated. Modified Poisson regression was used to estimate relative risk of obtaining cervical cancer screening within one yearor ever, stratified by residential area. RESULTS: Findings differed markedly by center and urban/rural status. At two health clinics, rural residents living the furthest away from the clinic (∼9 miles difference between quartile 4 and quartile 1) were more likely to be ever screened (RRs = 1.05 and 1.03, p-values < 0.05), while urban residents living the furthest away were less likely to be ever screened (RR = 0.85, p-value < 0.05). At the third center, only urban residents living the furthest away were more likely to be ever screened (RR = 1.02, p-value < 0.05). CONCLUSIONS: Increased travel distance significantly increased the likelihood of cervical cancer screening at two FQHC sites while significantly decreasing the likelihood of screening at the 3rd site. These findings underscore the importance of contextual and environmental factors that impact use of cervical cancer screening services.

A Comprehensive Framework to Evaluate Websites: Literature Review and Development of GoodWeb.

BACKGROUND: Attention is turning toward increasing the quality of websites and quality evaluation to attract new users and retain existing users. OBJECTIVE: This scoping study aimed to review and define existing worldwide methodologies and techniques to evaluate websites and provide a framework of appropriate website attributes that could be applied to any future website evaluations. METHODS: We systematically searched electronic databases and gray literature for studies of website evaluation. The results were exported to EndNote software, duplicates were removed, and eligible studies were identified. The results have been presented in narrative form. RESULTS: A total of 69 studies met the inclusion criteria. The extracted data included type of website, aim or purpose of the study, study populations (users and experts), sample size, setting (controlled environment and remotely assessed), website attributes evaluated, process of methodology, and process of analysis. Methods of evaluation varied and included questionnaires, observed website browsing, interviews or focus groups, and Web usage analysis. Evaluations using both users and experts and controlled and remote settings are represented. Website attributes that were examined included usability or ease of use, content, design criteria, functionality, appearance, interactivity, satisfaction, and loyalty. Website evaluation methods should be tailored to the needs of specific websites and individual aims of evaluations. GoodWeb, a website evaluation guide, has been presented with a case scenario. CONCLUSIONS: This scoping study supports the open debate of defining the quality of websites, and there are numerous approaches and models to evaluate it. However, as this study provides a framework of the existing literature of website evaluation, it presents a guide of options for evaluating websites, including which attributes to analyze and options for appropriate methods.

Using debate to educate young people in schools about antibiotic use and resistance: A before and after evaluation using a questionnaire survey.

INTRODUCTION: The use of debating as an educational tool is increasing in popularity. Students who take part in debates can develop a range of skills such as confidence and communication as well as gaining a greater understanding of the topic discussed. Within this study we have evaluated an antibiotic-resistant debate kit, assessing the ability of the debate lesson to improve student knowledge and awareness around antibiotics. METHODS: The debate lesson was delivered in seven schools across South West England to 235 students aged 13-16 years. Change in student knowledge was measured using before and after knowledge questionnaires. Student and teacher feedback and suggestions for improvements for the lesson were also collected through questionnaires and interviews. RESULTS: Quantitative questionnaires found a significant improvement in knowledge for most areas covered in the debate, particularly around the use of antibiotics to treat colds and bacteria developing resistance. Teachers felt their students engaged well with the debate session and made suggestions for minor modifications that could improve the lesson. CONCLUSIONS: The results suggest that the e-Bug antibiotic resistant debate kit is able to improve knowledge in young people around antibiotics and antibiotic resistance. Furthermore, the lesson was enjoyed by students and therefore this resource should be promoted more widely to teachers and schools.

Young People's Knowledge of Antibiotics and Vaccinations and Increasing This Knowledge Through Gaming: Mixed-Methods Study Using e-Bug.

BACKGROUND: e-Bug, led by Public Health England, educates young people about important topics: microbes, infection prevention, and antibiotics. Body Busters and Stop the Spread are 2 new e-Bug educational games. OBJECTIVE: This study aimed to determine students' baseline knowledge, views on the games, and knowledge improvement. METHODS: Students in 5 UK educational provisions were observed playing 2 e-Bug games. Before and after knowledge and evaluation questionnaires were completed, and student focus groups were conducted. RESULTS: A total of 123 junior and 350 senior students completed the questionnaires. Vaccination baseline knowledge was high. Knowledge increased significantly about antibiotic use, appropriate sneezing behaviors, and vaccinations. In total, 26 student focus groups were conducted. Body Busters was engaging and enjoyable, whereas Stop the Spread was fast-paced and challenging but increased vaccination and health behavior intentions. CONCLUSIONS: e-Bug games are an effective learning tool for students to enhance knowledge about microbes, infection prevention, and antibiotics. Game-suggested improvements should help increase enjoyment.

A Practical Approach to Establishing a Practice-Based Research Network Stakeholder Engagement Infrastructure.

INTRODUCTION: While there have been several articles detailing the importance of stakeholder engagement in research broadly and in practice-based research networks (PBRNs) specifically, few of these articles offer a replicable engagement approach that is detailed enough to translate to another setting. The goal of this article is to offer a detailed example of building stakeholder engagement infrastructure that could be replicated or translated to other settings. APPROACH: We offer a review of 1 regional PBRN's approach to building a stakeholder engagement infrastructure over a 2-year period by describing engagement activities deployed across a large, regional PBRN including a needs assessment around research and training conducted in each state of the network and a centralized conference where themes from that needs assessment were leveraged to produce a stakeholder-defined research agenda and elect a steering committee. RESULTS: Products from this process include the stakeholder-defined research agenda as well as a multi-level organizational framework for assessing facilitators and barriers in a large PBRN and an example of a framework of individualized stakeholder group preferences for engagement modalities. CONCLUSIONS: This article presents a detailed timeline and replicable approach to building a stakeholder engagement infrastructure in a regional PBRN. This article details a practical process that is embedded in the lived values of practice-based research.

A mixed methods pilot of Beat the Bugs: A community education course on hygiene, self-care and antibiotics.

Background: e-Bug is an international health education resource which support World Health Organization (WHO) public health recommendations by educating young people about microbes, hygiene and antibiotics use. The e-Bug team collaborated with Kingfisher Treasure Seekers to develop a six-session course for community groups called Beat the Bugs covering: microbes; hygiene; antibiotic use; and self-care. A pilot was used to inform further development and evaluation. Methods: Pilot courses with 9-12 adults with learning difficulties and young parents were delivered by community leaders and observed by researchers. Participants completed before and after knowledge questionnaires. Two participant focus groups and two course leader interviews explored views on the course and retention of knowledge. Results: Completed questionnaires and qualitative results showed an improvement in participant knowledge in each session; microbes and antibiotics sessions showed the greatest knowledge improvement. Self-care showed the greatest knowledge retention and participants reported behaviour change including an increase in appropriate hand-washing and tooth-brushing. Conclusion: The Beat the Bugs course is a useful intervention for communities to give individuals the knowledge and confidence to manage their own infection and change behaviour around hygiene, self-care and antibiotics. Beat the Bugs is freely available to download.

Can Gaming Increase Antibiotic Awareness in Children? A Mixed-Methods Approach.

BACKGROUND: e-Bug is a pan-European educational resource for junior and senior school children, which contains activities covering prudent antibiotic use and the spread, treatment, and prevention of infection. Teaching resources for children aged 7-15 years are complemented by a student website that hosts games and interactive activities for the children to continue their learning at home. OBJECTIVE: The aim of this study was to appraise young people's opinions of 3 antibiotic games on the e-Bug student website, exploring children's views and suggestions for improvements, and analyzing change in their knowledge around the learning outcomes covered. The 3 games selected for evaluation all contained elements and learning outcomes relating to antibiotics, the correct use of antibiotics, and bacteria and viruses. METHODS: A mixed methodological approach was undertaken, wherein 153 pupils aged 9-11 years in primary schools and summer schools in the Bristol and Gloucestershire area completed a questionnaire with antibiotic and microbe questions, before and after playing 3 e-Bug games for a total of 15 minutes. The after questionnaire also contained open-ended and Likert scale questions. In addition, 6 focus groups with 48 students and think-aloud sessions with 4 students who had all played the games were performed. RESULTS: The questionnaire data showed a significant increase in knowledge for 2 out of 7 questions (P=.01 and P<.001), whereas all questions showed a small level of increase. The two areas of significant knowledge improvement focused around the use of antibiotics for bacterial versus viral infections and ensuring the course of antibiotics is completed. Qualitative data showed that the e-Bug game "Body Busters" was the most popular, closely followed by "Doctor Doctor," and "Microbe Mania" the least popular. CONCLUSIONS: This study shows that 2 of the e-Bug antibiotic educational games are valuable. "Body Busters" effectively increased antibiotic knowledge in children and had the greatest flow and enjoyment. "Doctor Doctor" also resulted in increased knowledge, but was less enjoyable. "Microbe Mania" had neither flow nor knowledge gain and therefore needs much modification and review. The results from the qualitative part of this study will be very important to inform future modifications and improvements to the e-Bug games.
