Comprehensive review of emerging contaminants: Detection technologies, environmental impact, and management strategies.

Emerging contaminants (ECs) are a diverse group of unregulated pollutants increasingly present in the environment. These contaminants, including pharmaceuticals, personal care products, endocrine disruptors, and industrial chemicals, can enter the environment through various pathways and persist, accumulating in the food chain and posing risks to ecosystems and human health. This comprehensive review examines the chemical characteristics, sources, and varieties of ECs. It critically evaluates the current understanding of their environmental and health impacts, highlighting recent advancements and challenges in detection and analysis. The review also assesses existing regulations and policies, identifying shortcomings and proposing potential enhancements. ECs pose significant risks to wildlife and ecosystems by disrupting animal hormones, causing genetic alterations that diminish diversity and resilience, and altering soil nutrient dynamics and the physical environment. Furthermore, ECs present increasing risks to human health, including hormonal disruptions, antibiotic resistance, endocrine disruption, neurological effects, carcinogenic effects, and other long-term impacts. To address these critical issues, the review offers recommendations for future research, emphasizing areas requiring further investigation to comprehend the full implications of these contaminants. It also suggests increased funding and support for research, development of advanced detection technologies, establishment of standardized methods, adoption of precautionary regulations, enhanced public awareness and education, cross-sectoral collaboration, and integration of scientific research into policy-making. By implementing these solutions, we can improve our ability to detect, monitor, and manage ECs, reducing environmental and public health risks.

Strategies for engaging older adults and informal caregivers in health policy development: A scoping review.

BACKGROUND: Care for older adults is high on the global policy agenda. Active involvement of older adults and their informal caregivers in policy-making can lead to cost-effective health and long-term care interventions. Yet, approaches for their involvement in health policy development have yet to be extensively explored. This review maps the literature on strategies for older adults (65+ years) and informal caregivers' involvement in health policy development. METHOD: As part of the European Union TRANS-SENIOR program, a scoping review was conducted using the Joanna Briggs Institute's methodology. Published and grey literature was searched, and eligible studies were screened. Data were extracted from included studies and analysed using the Multidimensional Framework for Patient and Family Engagement in Health and Healthcare. RESULTS: A total of 13 engagement strategies were identified from 11 publications meeting the inclusion criteria. They were categorized as "traditional", "deliberative" and "others", adopting the World Bank's categorization of engagement methods. Older adults and informal caregivers are often consulted to elicit opinions and identify priorities. However, their involvement in policy formulation, implementation and evaluation is unclear from the available literature. Findings indicate that older adults and their informal caregivers do not often have equal influence and shared leadership in policy-making. CONCLUSION: Although approaches for involving older adults and their informal caregivers' involvement were synthesized from literature, we found next to no information about their involvement in policy formulation, implementation and evaluation. Findings will guide future research in addressing identified gaps and guide policy-makers in identifying and incorporating engagement strategies to support evidence-informed policy-making processes that can improve health outcomes for older adults/informal caregivers.

Policy framework that addresses malnutrition in Namibia: A retrospective qualitative review.

BACKGROUND: Although Namibia has made strides in improving the policy enabling environment, eradication of malnutrition is still elusive. OBJECTIVE: This review was aimed at determining the extent to which food and nutrition-related policies in Namibia address malnutrition. METHODS: This study used a qualitative approach by retrospectively analysing policy frameworks that address malnutrition in Namibia from 1991 to 2022. The analysis employed the policy triangle framework to elucidate the contextual factors, content, actors and process involved in the policy development. Moreover, a comparative analysis of Namibian policies and those of other southern African countries was undertaken. RESULTS: The review showed that there is a considerable degree of coherence in policy goals and strategies to address malnutrition despite parallel coordination structures. Policy process involved limited consultations with local communities which might have jeopardised the formulation of community problem-tailored interventions, ownership and participation in policy implementation. There is a strong political commitment to the eradication of malnutrition in Namibia. The Office of the Prime Minister played a leading role in policy development. Influential actors such as the UN agencies elevated the nutrition agenda. Further, the Namibian policy framework was generally similar to those of other southern African countries. CONCLUSIONS: The review showed that Namibia has relevant and comprehensive policies to address malnutrition, however, contextual factors indicated high levels of malnutrition still exist in the communities. Further research is needed to understand the barriers and enablers to optimal nutrition for children under five years in Namibia.

Towards a national policy on nursing education and training: an imperative framework for integrating nursing education within South Africa's post-school education system.

The aim of this study article is to present an analysis of the first national policy framework, which provides a coherent approach to integrating nursing education into a newly defined band for higher education programmes in South Africa. The significance of this policy framework is ensuring the seamless transition from legacy nursing programmes to NQF-registered nursing programmes. It explores the agenda-setting process, analyses the prevailing context and outlines the rationale for the policy. Walt and Gilson's policy triage analysis process outlines the key elements of the policy development process. Drawing upon Tarlov's two-phased public policy development process, the article outlines the steps completed in the policy development process. Recommendations are proposed to expand access, improve quality and diversify the provisioning of nursing education and training in South Africa.

The prevalence of developmental defects of enamel in people with cystic fibrosis: a systematic review.

BACKGROUND: Oral health impacts systemic health, individual well-being, and quality of life. It is important to identify conditions that may exacerbate oral disease to aid public health and policy development and promote targeted patient treatment strategies. Developmental defects can increase an individual's risk of dental caries, hypersensitivity, premature tooth wear, erosion, and poor aesthetics. As part of an ongoing study assessing oral health in adults with cystic fibrosis at Cork University Dental School and Hospital, a systematic review of available literature was conducted to assess the prevalence of enamel defects in people with cystic fibrosis. AIMS: To critically evaluate the literature to determine if the prevalence of developmental defects of enamel is higher in people with cystic fibrosis (PwCF). METHODS: Data Sources: Three online databases were searched Embase, Scopus, and Web of Science Core Collection. Studies that examined an association between cystic fibrosis and developmental defects of enamel were included in this systematic review. RESULTS: The initial search identified 116 publications from the following databases Embase, Web of Science Core Collection, and Scopus. Eleven studies were included for qualitative analysis. Nine studies concluded that PwCF had a higher prevalence of enamel defects than control people and one study found no difference in cystic fibrosis (CF) status. All studies had a risk of bias that may influence study results and their interpretation. CONCLUSIONS: The results of the systematic review show a consistent pattern that PwCF have a higher prevalence of DDE than people without CF. Genetic dysfunction, chronic systemic infections, and long-term antibiotic use are possible aetiological causes. This review highlights the need for future studies to investigate if DDEs are caused by the underlying CFTR mutation or as a consequence of disease manifestations and/or management.

'Having the dog as part of our family gives us hope': Experiences of the impact of assistance dogs on the occupational engagement of children with autism and their families.

BACKGROUND: Autism is a developmental disorder characterised by changes in social, communication, and behavioural performance. Assistance dogs can support children with autism to engage in everyday occupations. Despite more children being partnered with assistance dogs, there is limited research regarding the impact of assistance dogs on the occupational engagement of children with autism and their families, and further research is needed to fully understand the impact of this type of support within the Australian context. OBJECTIVES: To explore caregiver-reported experiences of an assistance dog on the occupational engagement of children with autism and their families. METHOD: Using a qualitative approach, semi-structured interviews were undertaken with six caregivers of seven children with autism, who each had an assistance dog. Interviews ranged from 45 to 60 minutes in duration. Data were transcribed verbatim and thematically analysed. Trustworthiness was maximised through independent recruitment, research team discussions, member checking, and a researcher reflective journal. FINDINGS: Three themes were identified: participation in everyday occupations prior to and after partnering with an assistance dog, increased engagement in everyday occupations, and impact of the assistance dog on the family unit. Assistance dogs were reported to progress children from community 'isolation' to 'freedom'. Participants reported the dog increased children's capacities through positively influencing completion of routines, increasing independence, and improving therapy engagement. Assistance dogs were viewed as supporting the whole family's occupational engagement. Some challenges were identified with the introduction of the assistance dog to the family unit, and with animal maintenance costs and time demands, public access rights, and limited government funding. CONCLUSION: This research identifies benefits and challenges for children who partner with autism assistance dogs. It provides insights to inform assistance animal referral, assessment, and support of assistance dogs in Australia for children with autism and occupational therapists working with them.

Academic contributions to the development of evidence and policy systems: an EPPI Centre collective autoethnography.

BACKGROUND: Evidence for policy systems emerging around the world combine the fields of research synthesis, evidence-informed policy and public engagement with research. We conducted this retrospective collective autoethnography to understand the role of academics in developing such systems. METHODS: We constructed a timeline of EPPI Centre work and associated events since 1990. We employed: Transition Theory to reveal emerging and influential innovations; and Transformative Social Innovation theory to track their increasing depth, reach and embeddedness in research and policy organisations. FINDINGS: The EPPI Centre, alongside other small research units, collaborated with national and international organisations at the research-policy interface to incubate, spread and embed new ways of working with evidence and policy. Sustainable change arising from research-policy interactions was less about uptake and embedding of innovations, but more about co-developing and tailoring innovations with organisations to suit their missions and structures for creating new knowledge or using knowledge for decisions. Both spreading and embedding innovation relied on mutual learning that both accommodated and challenged established assumptions and values of collaborating organisations as they adapted to closer ways of working. The incubation, spread and embedding of innovations have been iterative, with new ways of working inspiring further innovation as they spread and embedded. Institutionalising evidence for policy required change in both institutions generating evidence and institutions developing policy. CONCLUSIONS: Key mechanisms for academic contributions to advancing evidence for policy were: contract research focusing attention at the research-policy interface; a willingness to work in unfamiliar fields; inclusive ways of working to move from conflict to consensus; and incentives and opportunities for reflection and consolidating learning.

Representations of clinical practice guidelines and health equity in healthcare literature: An integrative review.

AIM: This paper reports an integrative review of international health literature that discusses health equity in relation to clinical practice guidelines (CPGs). BACKGROUND: Healthcare professionals (HCPs), policy makers, and decision makers rely on sound empirical evidence to make fiscally responsible and appropriate decisions about the allocation of health resources and health service delivery. CPGs provide statements and recommendations that aim to standardize care with an implicit goal of achieving equity of care among diverse populations. Developers of CPGs must be careful not to exacerbate inequity when making recommendations. As such, it is important to determine how equity is discussed within the context of CPGs. DESIGN: This integrative review was conducted according to integrative review methods as outlined by Whittemore and Knafl (2005), and Toronto and Remington (2020). These authors outlined a systematic process for the identification of relevant literature across health disciplines to examine the state of knowledge pertaining to a phenomenon such as health equity. SEARCH METHODS: The computerized databases PubMed, CINAHL, Cochrane, Embase, Medline, and Web of Science were searched using a combination of keywords. Search parameters included international peer-reviewed published, full-text, English language articles, editorials, and reports over the last decade (January 2011 to February 2022). A reference search of included articles was conducted to identify any additional articles. Dissertations and theses were not included. SEARCH OUTCOME: A total of 139 peer-reviewed English language articles were identified. RESULTS: The findings of this review revealed five main ways in which health equity is in context of CPGs including if they target or exacerbate inequity among disadvantaged populations, equity and CPG development, implementation, and evaluation, and checklists and tools to assist developers and users of CPG to consider equity. Although critical appraisal tools exist to assist users of CPGs assess and to evaluate how well CPGs address issues of equity, the definition of equity and how CPG development panels should incorporate and articulate it remains unclear and haphazard. As such, recommendations intended to be implemented by HCPs to optimize health equity remains diverse and unclear. CONCLUSION: The way equity is discussed within the reviewed health literature has implications for their uptake by and utility for HCPs. The ability of HCPs to implement CPGs may be hindered without an appreciation and integration of equity considerations across the various phases of CPG conceptualization, development, implementation, and evaluation, and their relevance and appropriateness to diverse geographic and socioeconomic contexts with variable access to health human resources and services. This situation could be improved if equity were more clearly articulated within all aspects of the CPG process. CLINICAL RELEVANCE: Understanding how equity is discussed in the literature relative to CPGs has implications for their uptake by and utility for HCPs in their goal of providing equitable health care. Successful implementation of CPGs with consideration equity could be improved if equity were more clearly articulated within all aspects of the CPG process including conceptualization, development, implementation, and evaluation.

Creating Age-Friendly Environments in a Smart Society in China: A Policy Review.

Technology is increasingly being integrated into Age-Friendly Environments (AFEs). This study explores how technology is manifested in AFE policies in China. We conducted a content analysis of 176 policies spanning seven years to identify the relationship between technology and AFEs and the characteristics of policy development. The findings indicate that technology plays a role in advancing a smart age-friendly society, particularly in terms of enhancing community support and health services and promoting social inclusion. The findings also reveal a list of policy actions and changes in collaborative leadership and strategic priorities throughout policy development. This study emphasizes the need for ongoing policy attention to technology as an integrated component of AFE policies.

Building on the Health Policy Analysis Triangle: Elucidation of the Elements.

The health policy triangle first presented in the 20th century by Walt and Gilson has been extensively used at local, national, regional, and international levels to assess health policies related to communicable and non-communicable diseases, physical and mental health, antenatal and postnatal care, and human resources, services, and systems. However, the framework lacks intricate details for the four pillars in the triangle viz: 'content,' 'context', 'actors', and 'processes. We propose a checklist of elements to be considered for each pillar; to ease and enhance the process of policy analyses for researchers and policymakers across the globe, including low- and middle-income countries. We suggest using Leichter's categorization of situational, structural, cultural, and environmental factors for comprehensive contextual assessment. Kingdon's multiple streams framework can be applied to determine the 'window of opportunity' allowing the politics, policy, and problem streams to unite, giving birth to the formulation of policies. Lastly, stakeholders' analyses expounding the power, influence, interest, and involvement of intrinsic, extrinsic, implicit, and explicit players should be applied to explore the 'actors' in policy analyses. Robust policy analyses for generating evidence are of paramount importance for policymakers for informed decision-making. Our approach of dis-entangling and elaborating the pillars of the triangle will be helpful for health systems researchers at sub-national, national, regional and global levels to serve as a basis for evidence-based informed decision-making.

First Nations Australians' self-determination in health and alcohol policy development: a Delphi study.

BACKGROUND: Recognition of the role of structural, cultural, political and social determinants of health is increasing. A key principle of each of these is self-determination, and according to the United Nations (2007), this is a right of Indigenous Peoples. For First Nations Australians, opportunities to exercise this right appear to be limited. This paper explores First Nations Australian communities' responses to reducing alcohol-related harms and improving the health and well-being of their communities, with a focus on understanding perceptions and experiences of their self-determination. It is noted that while including First Nations Australians in policies is not in and of itself self-determination, recognition of this right in the processes of developing health and alcohol policies is a critical element. This study aims to identify expert opinion on what is needed for First Nations Australians' self-determination in the development of health- and alcohol-related policy. METHODS: This study used the Delphi technique to translate an expert panel's opinions into group consensus. Perspectives were sought from First Nations Australians (n = 9) and non-Indigenous Peoples (n = 11) with experience in developing, evaluating and/or advocating for alcohol interventions led by First Nations Australians. Using a web-based survey, this study employed three survey rounds to identify and then gain consensus regarding the elements required for First Nations Australians' self-determination in policy development. RESULTS: Twenty panellists (n = 9 First Nations Australian) participated in at least one of the three surveys. Following the qualitative round 1 survey, six main themes, 60 subthemes and six examples of policy were identified for ranking in round 2. In round 2, consensus was reached with 67% of elements (n = 40/60). Elements that did not reach consensus were repeated in round 3, with additional elements (n = 5). Overall, consensus was reached on two thirds of elements (66%, n = 43/65). CONCLUSIONS: Self-determination is complex, with different meaning in each context. Despite some evidence of self-determination, systemic change in many areas is needed, including in government. This study has identified a starting point, with the identification of elements and structural changes necessary to facilitate First Nations Australian community-led policy development approaches, which are vital to ensuring self-determination.

Impact of emotional intelligence on work performance: The mediating role of occupational stress among nurses.

INTRODUCTION: An occupational stress was reported as an inhibitor of optimal performance among nurses. Emotional intelligence (EI) has emerged as a successful behavioral buffer against occupational stress and as a facilitator for better performance. This study aimed to investigate the potential relationship between nurses' EI and their work performance; and to examine the mediating role of occupational stress. DESIGN: A predictive correlational design was adopted. METHOD: Self-reported questionnaires were administered to 391 full-time bedside nurses recruited from one of the big hospitals in Saudi Arabia, between April and June 2021. Data were coded and analyzed using IBM SPSS version 25.0. Simple and multiple linear regression analyses were used to test the hypotheses. The significance level for all tests was set at p ≤ 0.05. Bonferroni correction method was used to control the family-wise error rate. RESULTS: The findings revealed an affirmative association between nurses' EI and work performance (ß = 0.69, p < 0.001; r2  = 0.483). Additionally, an inverse association was established between nurses' EI and their perception of occupational stress (ß = -0.54, p < 0.001; r2  = 0.286), and between nurses' perception of occupational stress and work performance (ß = -0.52; p < 0.001; r2  = 0.226). Additionally, our results showed that occupational stress played a mediating role in the relationship between nurses' EI and work performance. CONCLUSION: This study presented a novel framework that includes two factors affecting work performance among nurses in Saudi Arabia. Our results suggest that EI is vital for effective work performance among nurses. Additionally, EI was found to be a useful coping strategy against occupational stress. CLINICAL RELEVANCE: EI has been described as a valuable asset for better performance and effective group cohesiveness among nurses. Optimal nursesá¾½ performance leads to meeting patientsá¾½ needs and organizational goals.

Barriers and facilitators to the introduction of import duties designed to prevent noncommunicable disease in Tonga: a case study.

BACKGROUND: In Tonga, import duties were lowered on tinned fish and seafood in 2013 and raised on soft drinks, dripping and other animal fats. Additional import duties were applied to soft drinks and dripping and other fats in 2016 and duties were also applied to high fat meats, mutton flaps and turkey tails. The objective of this study was to describe barriers to and facilitators of these import duties from a policy-maker perspective. METHODS: A case study was conducted to analyse implementation of policies originally modelled by the Pacific Obesity Prevention in Communities project to reduce mortality in the Kingdom of Tonga. Policymakers (n = 15) from the Ministries of Revenue, Health, Finance and Labour and Commerce involved in the development and implementation of Tonga's food-related policies participated in key-informant interviews. RESULTS: The main facilitator of import duties were strong leadership and management, cross-sector collaboration, awareness raising and advocacy, nature of the policy, and the effective use of data to model policy impacts and inform the general public. The absence of clear lines of responsibility and a decline in collaboration over time were identified as barriers to implementation of the import duties. CONCLUSION: In a small Island state implementing import duties to prevent non-communicable disease can be straight forward providing policymakers and the community have a shared understanding of the health and economic costs of NCDs.

Promoting Community Health Worker Leadership in Policy Development: Results from a Louisiana Workforce Study.

Community health workers (CHWs) are effective in improving public health, and many states are developing policy to support the workforce. In 2019, the Louisiana legislature created the CHW Workforce Study Committee (Committee) of at least half CHWs to study the workforce and provide the state with policy recommendations. The Committee followed national best practices in CHW engagement. A CHW and an academic team identified CHWs and employers statewide, administered a survey in partnership with a CHW professional association, and conducted in-depth interviews with CHWs and employers. Descriptive statistics were used to summarize survey data and applied thematic analysis was used to interpret interview transcripts. Sixty-five CHWs and 37 employers participated in the survey. Twenty-one CHWs and 15 employers completed interviews. Survey data indicated that Louisiana CHW roles and activities are consistent with national research. Interviews revealed a lack of knowledge about CHWs among key stakeholders, CHW workforce challenges including lack of community and professional resources, and differing ideas about the value of common workforce development practices such as standardized training and credentialing. Findings suggest a need for widespread education about CHWs and support for CHW participation in professional associations to address common workforce challenges. CHW co-leadership and partnering with a CHW professional association enabled successful study execution and full participation of CHWs in the formation of Committee recommendations. A subset of Committee members, made up of at least half CHWs, continues to meet to expand and support the workforce.

Nurses' and midwives' perspectives on participation in national policy development, review and reforms in Ghana: a qualitative study.

BACKGROUND: The World Health Organization has admonished member countries to strive towards achieving universal health coverage (UHC) through actionable health policies and strategies. Nurses and midwives have instrumental roles in achieving UHC via health policy development and implementation. However, there is a paucity of empirical data on nurses and midwives' participation in policy development in Ghana. The current study explored nurses and midwives' participation in policy development, reviews and reforms in Ghana. METHODS: A qualitative descriptive exploratory design was adopted for this study. One-on-one individual interviews were conducted after 30 participants were purposefully selected. Data was audiotaped with permission, transcribed and analyzed inductively using the content analysis procedures. RESULTS: Two main themes emerged from the data: participation in policy development and perspectives on policy reviews and reforms. The findings showed that during health policy development and reviews, nurses in Ghana were overlooked and unacknowledged. Policy reforms regarding bridging the pre-service preparation gap, staff development and motivation mechanisms and influence on admission into nursing schools were raised. CONCLUSION: The authors concluded that nurses and midwives are crucial members of the healthcare systems and their inputs in policy development and reviews would improve health delivery in Ghana.

Partnership Through Integration: Perianesthesia Policy Standardization.

PURPOSE: To develop system-wide perianesthesia policies, through partnerships, across 11 acute care hospitals and 1 ambulatory surgery center. DESIGN: A partnership culture was created and maintained throughout the development and integration of multiple site-based policies into system policies. METHODS: Policies were built using evidence-based practice and professional organizational standards with an emphasis on quality, safety, and standardization of patient care. Early and ongoing partnerships with key stakeholders were maintained in order to effectively develop the policies. FINDINGS: More than 50 independent policies across 11 acute care hospitals and 1 ambulatory surgery center were integrated and updated into 4 main perianesthesia nursing policies. CONCLUSIONS: Flexibility and partnership with key stakeholders throughout the policy process was instrumental for early detection of barriers and the successful development of perianesthesia nursing policies.

Participation of nurse managers in the health policy process: a qualitative study of barriers and facilitators.

AIM: To explore the barriers and facilitators concerning nurse managers' participation in the health policy-making process. BACKGROUND: Despite encouragement for participation in policy-making, nurse managers are seldom involved in this process. METHODS: A qualitative descriptive research design based on purposive sampling was conducted. Semi-structured one-to-one interviews were conducted with nurse managers and key informants (n = 16). Interviews were digitally recorded, transcribed verbatim, and analyzed by thematic analysis. The Standards for Reporting Qualitative Research (SRQR) checklist was applied to study reporting. FINDINGS: Three levels of barriers were found to nurse managers' participation in health policy-making. The individual level included weakness in characteristics of nurse managers, and the organizational level constituted the inefficient structure. In addition, the environment-related level encompassed external barriers to the organization. Finally, three facilitators with the potential were identified for improving nurse managers' participation in the policy-making process, including improvements in collaboration and communication, governmental and non-governmental organizational activities, and reforms in the health policy-making process. CONCLUSION: Nurse managers need to use the window of opportunity to participate in health policy-making. More importantly, they should be informed about health policy in order to meet the demands of the rapidly changing healthcare environment. Drawing upon their professional organizations and positions, nurse leaders require to network and make a space to stimulate their participation in the policy. IMPLICATIONS FOR NURSING POLICY AND HEALTH POLICY: Nurse managers need to develop political skills and utilize strategies to help their participation in health policy-making, leading to better implementation of policies, efficiency, and effectiveness in the health system.

Involvement of Jordanian Head Nurses' in Health Policy Development: A Cross-Sectional Study.

BACKGROUND: Despite the importance of involving nurses in health policy, nurse's involvement faces many challenges. Literature showed that there is a low level of nurses' and nurse leaders' involvement in health policy development. AIM: The aims of this study were to examine (a) the level of Jordanian head nurses' involvement in health policy development and their perceived benefits and barriers; (b) the relationships between level of knowledge, competence, and interest in health policy and the level of involvement in health policy development; and (c) the relationship between the level of self-efficacy (efficacy expectation and outcome expectation) and the level of involvement in health policy development. METHODS: A cross-sectional descriptive correlational study design was adopted in this study. A convenience sampling of 250 participants from hospitals affiliated to three health sectors in Jordan (private, governmental, and university) were recruited to complete a self-administered questionnaire. Descriptive statistics and Pearson correlation coefficient were used to answer the study questions. RESULTS: The results revealed a moderate level of involvement of head nurses in the policy development. The most frequent cited political activity was "providing written reports, consultations, research." "Lack of time" was the most perceived barrier, while "improving the health of the public" was the most perceived benefit. Workshops or sessions at conferences is the most indicated source of knowledge. Participants had an excellent level of skills with positive relationships between the competence and both of the levels of professional and personal involvement in health policy. Participants reported a low level of confidence in performing political activities as well as the impact of such activities on health outcomes. Positive relationship was indicated between self-efficacy and the levels of professional and personal involvement in political activities.Implications: Health policies affect nurses and their practice. Overcoming the barriers and enhancing the levels of head nurses' knowledge and competence regarding health policies can help activating their roles in health policy development process. This will help in activating nurses' role in health policy development, which in turn will have a positive impact on health outcomes.

Access to Care as a Barrier to Mammography for Black Women.

Racial disparities in breast cancer screening, morbidity, and mortality persist for Black women. This study examines Black women's mammography beliefs and experiences with specific focus on barriers to mammography access in an urban city in the South East, United States. This retrospective, qualitative study used Penchansky and Thomas' conceptualization of health care access as the framework for the data analysis. In-depth, semistructured interviews were conducted with 39 Black women. Structural and personal factors continue to create barriers to mammography among Black women. Barriers to mammography were identified for each of the Penchansky and Thomas five dimensions of access to care: accessibility, affordability, availability, accommodation, and acceptability. Clinical practice strategies to increase mammography screening in Black women must be multifactorial, patient-centered, and culturally congruent. Policy development must address the structural barriers to mammography screening through expansion of health insurance coverage and increased accessibility to health care.

Alternative observational designs to estimate the effectiveness of one dose of oral cholera vaccine in Lusaka, Zambia.

We conducted a matched case-control (MCC), test-negative case-control (TNCC) and case-cohort study in 2016 in Lusaka, Zambia, following a mass vaccination campaign. Confirmed cholera cases served as cases in all three study designs. In the TNCC, control-subjects were cases with negative cholera culture and polymerase chain reaction results. Matched controls by age and sex were selected among neighbours of the confirmed cases in the MCC study. For the case-cohort study, we recruited a cohort of randomly selected individuals living in areas considered at-risk of cholera. We recruited 211 suspected cases (66 confirmed cholera cases and 145 non-cholera diarrhoea cases), 1055 matched controls and a cohort of 921. Adjusted vaccine effectiveness of one dose of oral cholera vaccine (OCV) was 88.9% (95% confidence interval (CI) 42.7-97.8) in the MCC study, 80.2% (95% CI: 16.9-95.3) in the TNCC design and 89.4% (95% CI: 64.6-96.9) in the case-cohort study. Three study designs confirmed the short-term effectiveness of single dose OCV. Major healthcare-seeking behaviour bias did not appear to affect our estimates. Most of the protection among vaccinated individuals could be attributed to the direct effect of the vaccine.
