Mitigating the impact of air pollution on dementia and brain health: Setting the policy agenda.

BACKGROUND: Emerging research suggests exposure to high levels of air pollution at critical points in the life-course is detrimental to brain health, including cognitive decline and dementia. Social determinants play a significant role, including socio-economic deprivation, environmental factors and heightened health and social inequalities. Policies have been proposed more generally, but their benefits for brain health have yet to be fully explored. OBJECTIVE AND METHODS: Over the course of two years, we worked as a consortium of 20+ academics in a participatory and consensus method to develop the first policy agenda for mitigating air pollution's impact on brain health and dementia, including an umbrella review and engaging 11 stakeholder organisations. RESULTS: We identified three policy domains and 14 priority areas. Research and Funding included: (1) embracing a complexities of place approach that (2) highlights vulnerable populations; (3) details the impact of ambient PM2.5 on brain health, including current and historical high-resolution exposure models; (4) emphasises the importance of indoor air pollution; (5) catalogues the multiple pathways to disease for brain health and dementia, including those most at risk; (6) embraces a life course perspective; and (7) radically rethinks funding. Education and Awareness included: (8) making this unrecognised public health issue known; (9) developing educational products; (10) attaching air pollution and brain health to existing strategies and campaigns; and (11) providing publicly available monitoring, assessment and screening tools. Policy Evaluation included: (12) conducting complex systems evaluation; (13) engaging in co-production; and (14) evaluating air quality policies for their brain health benefits. CONCLUSION: Given the pressing issues of brain health, dementia and air pollution, setting a policy agenda is crucial. Policy needs to be matched by scientific evidence and appropriate guidelines, including bespoke strategies to optimise impact and mitigate unintended consequences. The agenda provided here is the first step toward such a plan.

Paleoeconomy more than demography determined prehistoric human impact in Arctic Norway.

Population size has increasingly been taken as the driver of past human environmental impact worldwide, and particularly in the Arctic. However, sedimentary ancient DNA (sedaDNA), pollen and archaeological data show that over the last 12,000 years, paleoeconomy and culture determined human impacts on the terrestrial ecology of Arctic Norway. The large Mortensnes site complex (Ceavccageadgi, 70°N) has yielded the most comprehensive multiproxy record in the Arctic to date. The site saw occupation from the Pioneer period (c. 10,000 cal. years BP) with more intensive use from c. 4,200 to 2,000 cal. years BP and after 1,600 cal. years BP. Here, we combine on-site environmental archaeology with a near-site lake record of plant and animal sedaDNA. The rich animal sedaDNA data (42 taxa) and on-site faunal analyses reveal switches in human dietary composition from early-Holocene fish + marine mammals, to mixed marine + reindeer, then finally to marine + reindeer + domesticates (sheep, cattle, pigs), with highest reindeer concentrations in the last millennium. Archaeological evidence suggests these changes are not directly driven by climate or variation in population densities at the site or in the region, but rather are the result of changing socio-economic activities and culture, probably reflecting settlers' origins. This large settlement only had discernable effects on its hinterland in the last 3,600 years (grazing) and more markedly in the last 1,000 years through reindeer keeping/herding and, possibly domestic stock. Near-site sedaDNA can be linked to and validate the faunal record from archaeological excavations, demonstrating that environmental impacts can be assessed at a landscape scale.

The experience of bereavement on family caregivers of people with dementia in China.

BACKGROUND AND OBJECTIVES: Despite many studies on 'life after care' for family caregivers with dementia in Western societies, little is known about the bereavement experiences of family caregivers in China. The aim of this study was to explore the experience of bereavement on family members of people with dementia in China. It also hopes to inform end-of-life care within communities, providing a theoretical basis for improving the quality of life of bereaved family caregivers. METHODS: Interpretative phenomenological analysis approach was adapted for this study. Purposive sampling was used to recruit former family caregivers of people with dementia. Semi-structured in-depth interviews with 12 bereaved family caregivers were collected. Thematic analysis was used for data analysis. FINDINGS: Five themes were identified: recalling the past life, lack of support, uncertainty of the future, social withdrawal and acceptance and release. CONCLUSION: The experiences of bereavement on family members of people with dementia in China are socially and culturally complex. This article recommends that bereavement should be supported throughout the palliative process of community services and healthcare services. Providing all-round support and education on death and dying can help the family caregivers to pass through grief and help them to maintain their normal life.

A thematic analysis of Chinese people with dementia and family caregivers' experiences of home care in China.

Ageing in place is a key principle of older care services in many countries, especially in China where the social convention, cultural expectation and legal obligation emphasise that looking after parents is the children's responsibility. As a result, the majority of older, frail Chinese have been cared for at home by their families. Previous studies have argued that being cared for at home contributes positively to the well-being and quality of life of older people and to economic cost. However, due to the sociocultural, economic and demographic changes in China, older people and their family caregivers are facing many challenges as they 'age in place' at home. This study aims to explore the meaning of family supported home care in China from the perspectives of people with dementia and family caregivers. The study is based on qualitative data collected from 24 people with dementia and family caregivers recruited from one mental health centre in Shandong province, China. Three main themes and nine subthemes were found: home care may create a sense of social isolation; home care is a burden; home care versus institutional care. The study suggests that while home care may bring social and psychological benefits, it also can be a barrier to building social connection, receiving social support, and other related services in China.

Tensions in dementia care in China: An interpretative phenomenological study from Shandong province.

AIMS: The study aims to analyse the tensions and the challenges of dementia care that are experienced by people with dementia and their family caregivers in China. BACKGROUND: China has the largest dementia population in the world; however, dementia care services and related support services are still developing. Caring for a person with dementia is very challenging, as evidenced by many studies. As the majority of people with dementia are looked after by their family in their homes in China, it is very important to understand what people with dementia and their family caregivers are experiencing in the context of dementia care services that are in the process of developing. DESIGN: Interpretative phenomenological analysis (IPA) was used. METHOD: Semi-structured individual interviews with 24 participants (10 people with dementia and 14 unrelated family caregivers) recruited from a mental health centre in Shandong Province. FINDINGS: Three main themes emerged that highlighted unmet need: (a) Lack of support services, (b) Insufficient institutional care and (c) Social attitude and social stigma towards dementia. CONCLUSIONS: These themes reveal the challenges that the participants face in the context of dementia care services that are in the process of development in China; and how their lived experiences have been affected by the constraints of social support, public services, healthcare access, long-term care services and social stigma. IMPLICATIONS FOR PRACTICE: This study highlights the tensions that are identified by people with dementia and family caregivers. The research recommends that more support services would be beneficial for this group and would also enhance family support dementia care in China. Looking after an older family member is a culturally, socially and legally embodied norm in Chinese society, so it is important to address education for dementia awareness and the sustainability of family support care services in China by providing dementia services and resources to support both people with dementia and family caregivers.

Nursing students' learning dynamics with clinical information and communication technology: A constructive grounded theory approach.

BACKGROUND: The learning of nursing students can be facilitated through direct and/or indirect experiences of using clinical information and communication technology during clinical placements. However, nursing students experience difficulties in using technology for learning. Despite the difficulties, nursing students' learning dynamics with technology in real clinical contexts is poorly understood. OBJECTIVES: To develop a theoretical model by identifying nursing students' learning dynamics with clinical information and communication technology and the factors influencing the dynamics. DESIGN: A constructivist grounded theory approach was employed in order to develop the theoretical model. SETTINGS: This research was conducted by recruiting nursing students from four universities in Seoul, South Korea. PARTICIPANTS: Sixteen fourth year nursing students were recruited by purposive sampling. METHODS: This research collected qualitative interview data in up to four rounds of interviews using open-ended and semi-structured interview questions. A total of 23 interviews were conducted. The data were transcribed verbatim. All interview data were analysed using three coding methods; initial, focused, and theoretical coding. NVivo 11 was used for data management. RESULTS: This research developed a theoretical model of nursing students' learning dynamics with clinical information and communication technology. The model explains three dynamics that influence nursing students' use of clinical information and communication technology (interpersonal, organisational and emotional dynamics) and the students' responses regarding the dynamics for learning in clinical contexts. CONCLUSIONS: Nursing educators can use the theoretical model to understand how best to support nursing students in navigating their clinical environments to build competency in using clinical information and communication technology.

Participant outcomes and preferences in Alzheimer's disease clinical trials: The electronic Person-Specific Outcome Measure (ePSOM) development program.

INTRODUCTION: Current pharmacological interventions for Alzheimer's dementia delay symptom progression for about a year. Although the outcomes in earlier disease states may include changes in biomarkers, the clinical effectiveness of any intervention can ultimately only be assessed by a patient's self-reported well-being. A better understanding of earlier manifestations of Alzheimer's disease and the drive for relevant outcome measures, allied to technological advances in artificial intelligence, have mediated the electronic Person-Specific Outcome Measure (ePSOM) development program. METHODS: There are 4 sequential stages in the ePSOM development program-(1) literature review, (2) focus group study, (3) national survey, and (4) development of an app for capturing person-specific outcomes. Here, we report the overall approach to the program incorporating our literature review on patient-reported outcome measures and patient preferences in the Alzheimer's disease population. RESULTS: Alzheimer's disease trials do not use any patient-reported outcome measures. Quality of life measures are often used as proxies for this, but they do not capture individual needs. Therefore, trials currently fail to reflect the participant's aspirations for effect but rather default to clinicostatistical measure of cognition and function. There is no implementation of patient preferences despite evidence that understanding preferences may influence adherence to treatment. DISCUSSION: It is important to consider preferences for an intervention and use PROMs for the measure of effectiveness given that both risk and benefit are judged by the recipient of the treatment. The ePSOM development program will deliver the methodology for incorporating meaningful outcomes in clinical trials to expand upon current biological and clinical measurements of effectiveness.

How do Korean nursing students build knowledge? A constructivist grounded theory study.

INTRODUCTION: Nursing is a knowledge-intensive profession. Therefore, to cope with the demands of the nursing role, nursing students need to become competent in managing information to build nursing knowledge. However, nursing students' knowledge building process is poorly understood. This research aimed to explore (1) nursing students' dynamics of how they process nursing information for knowledge building and (2) nursing students' learning context in South Korea for their knowledge building. METHODS: A constructivist grounded theory approach was used for this research. Data collection was achieved through four rounds of intensive individual and group interviews with 16 fourth year nursing students in South Korea. The collected data were coded by initial, focused and theoretical coding methods. Constant comparison analysis between data, codes, memos and categories was applied. RESULTS: This research identified knowledge building dynamics consisting of three cognitive processes: connecting with information, deciding to accept information and building knowledge. Five motivational factors, including learners' interest, necessity of information, volition to learn, utility of information and the frequency of information that influence the processes were discovered. Moreover, four knowledge stages of memorising, understanding, synthesising and applying and creating emerged. CONCLUSIONS: This is the first empirical study on knowledge building dynamics in educational environments for healthcare professionals. The findings of this research provide nursing educators with a practical model that can be used to improve nursing curricula in facilitating students' knowledge building processes. Moreover, a deeper understanding of sociocultural influences on nursing education can assist educators to adapt and generalise the findings to their pedagogical contexts, providing a culturally sensitive and relevant approach to nursing education.

A Seat Around the Table: Participatory Data Analysis With People Living With Dementia.

The involvement of "people with experience" in research has developed considerably in the last decade. However, involvement as co-analysts at the point of data analysis and synthesis has received very little attention-in particular, there is very little work that involves people living with dementia as co-analysts. In this qualitative secondary data analysis project, we (a) analyzed data through two theoretical lenses: Douglas's cultural theory of risk and Tronto's Ethic of Care, and (b) analyzed data in workshops with people living with dementia. The design involved cycles of presenting, interpreting, representing and reinterpreting the data, and findings between multiple stakeholders. We explore ways of involving people with experience as co-analysts and explore the role of reflexivity, multiple voicing, literary styling, and performance in participatory data analysis.

Nursing students' learning dynamics and influencing factors in clinical contexts.

Clinical placements are essential for students to develop clinical skills to qualify as nurses. However, various difficulties encountered by nursing students during their clinical education detract from developing clinical competencies. This constructivist grounded theory study aims to explore nursing students' experiences in clinical nursing education, and to identify the factors that influence the clinical education students receive. Twenty-one individual and six group semi-structured interviews were conducted with sixteen fourth year nursing students and four registered nurses. This research identified six factors that influence nursing students' clinical education: interpersonal, socio-cultural, instructional, environmental, emotional and physical factors. The research has developed a dynamic model of learning in clinical contexts, which offers opportunities to understand how students' learning is influenced multifactorially during clinical placements. The understanding and application of the model can improve nursing instructional design, and subsequently, nursing students' learning in clinical contexts.

Pathological and phylogenetic characterization of Amphibiothecum sp. infection in an isolated amphibian (Lissotriton helveticus) population on the island of Rum (Scotland).

Outbreaks of cutaneous infectious disease in amphibians are increasingly being attributed to an overlooked group of fungal-like pathogens, the Dermocystids. During the last 10 years on the Isle of Rum, Scotland, palmate newts (Lissotriton helveticus) have been reportedly afflicted by unusual skin lesions. Here we present pathological and molecular findings confirming that the pathogen associated with these lesions is a novel organism of the order Dermocystida, and represents the first formally reported, and potentially lethal, case of amphibian Dermocystid infection in the UK. Whilst the gross pathology and the parasite cyst morphology were synonymous to those described in a study from infected L. helveticus in France, we observed a more extreme clinical outcome on Rum involving severe subcutaneous oedema. Phylogenetic topologies supported synonymy between Dermocystid sequences from Rum and France and as well as their distinction from Amphibiocystidium spp. Phylogenetic analysis also suggested that the amphibian-infecting Dermocystids are not monophyletic. We conclude that the L. helveticus-infecting pathogen represents a single, novel species; Amphibiothecum meredithae.

Narrative citizenship, resilience and inclusion with dementia: On the inside or on the outside of physical and social places.

There has been little research that addresses the importance of place in enabling resilience and citizenship - most to date focussing on these as a characteristic of the individual. This paper reports on findings from a qualitative study that aimed to explore the everyday experiences of living with dementia within rural and semi-urban communities. Data collection included a sequence of four research diaries and interviews with 13 families living at home with dementia and interviews with service providers and commissioners (a total of 57 diaries, 69 interviews with people living with dementia and 6 interviews with service providers and commissioners). Key themes identified included: Others Knowing and Responding; Socially Withdrawing and Feeling Excluded; Sustaining and Changing Activities; Belonging and Estrangement from Place; Engaging Services and Supports. The study found that familiarity with people and place can be supportive, and these factors support a narrative citizenship in which people can tell a story of inclusion and feeling on the inside. However, this familiarity with place may also create a social barrier and a sense of estrangement, or being on the outside. Narrative citizenship allows us to explore how people with dementia position themselves in relation to others and in so doing, negotiate their own and other's understandings of dementia. It also allows for people to tell stories about themselves in relation to their sense of belonging in a social and physical place, which augment the personal and political approaches to citizenship and thus offers an approach that enhances individualised yet collective understandings of living with dementia.

"We're all thrown in the same boat ": A qualitative analysis of peer support in dementia care.

Peer support is well established in fields such as the disability movement and mental health and is increasingly recognised as one way of enabling support by and for people with a diagnosis of dementia and their immediate carers. It was central to the implementation of the National Dementia Strategy (NDS) for England, when 40 demonstration sites were established. This mixed-methods study included in-depth qualitative interviews with people living with dementia (n = 101) and staff/stakeholders (n = 82) at 8 of the 40 sites. Data analysis was a five-stage process: coding framework developed (using 25 transcripts); further development of the framework (using a further 70 transcripts); development of emerging themes; modelling of themes and verification of models based on the entire data set. Peer support had positive emotional and social impact that was rooted in identification with others, a commonality of experience and reciprocity of support. There was also a contrast between the quality of peer support and support from professionals. This emphasises the significance of lived experience and promoting a strength-based approach to interpersonal support that is enabling and challenges a deficit approach to understanding dementia.

Nursing students' attitudes towards information and communication technology: an exploratory and confirmatory factor analytic approach.

AIM: The aim of this study was to develop and psychometrically test a shortened version of the Information Technology Attitude Scales for Health, in the investigation of nursing students with clinical placement experiences. BACKGROUND: Nurses and nursing students need to develop high levels of competency in information and communication technology. However, they encounter statistically significant barriers in the use of the technology. Although some instruments have been developed to measure factors that influence nurses' attitudes towards technology, the validity is questionable and few studies have been developed to test the attitudes of nursing students, in particular. DESIGN: A cross-sectional survey design was performed. METHODS: The Information Technology Attitude Scales for Health was used to collect data from October 2012-December 2012. A panel of experts reviewed the content of the instrument and a pilot study was conducted. Following this, a total of 508 nursing students, who were engaged in clinical placements, were recruited from six universities in South Korea. Exploratory and confirmatory factor analyses were performed and reliability and construct validity were assessed. RESULTS: The resulting instrument consisted of 19 items across four factors. Reliability of the four factors was acceptable and the validity was supported. CONCLUSIONS: The instrument was shown to be both valid and reliable for measuring nursing students' attitudes towards technology, thus aiding in the current understandings of this aspect. Through these measurements and understandings, nursing educators and students are able to be more reflexive of their attitudes and can thus seek to develop them positively.

Dementia and relationships: experiences of partners in minority ethnic communities.

AIM: This article is a report of a study aimed at examining the experiences of partners of people with dementia in two minority ethnic communities. BACKGROUND: Cultural background is important in how people perceive the effects of dementia and respond to them. To date there has been little research on the experiences of minority ethnic partners in the U.K. METHOD: Using a constructivist grounded theory approach data collection took place in London, England, over an 18-month period between 2007 and 2009. A total of 43 in-depth interviews were conducted with seven Greek Cypriot and six African Caribbean partners of people with dementia. FINDINGS: The outcomes of the study revealed partners of people with dementia engaged in an ongoing process of 'redefining relationships'. Greek Cypriot partners tended to emphasize family relationships whilst African Caribbean partners tended to view themselves primarily as an individual or as part of a couple. CONCLUSION: Increased understanding of how dementia is experienced by partners of people from specific ethnic groups with dementia can equip nurses to give culturally appropriate advice and support. The study findings suggest that ethnicity alone cannot account for individual responses to dementia in a partner, and therefore awareness of cultural factors needs to be balanced with sensitivity to the unique life experience and relationships of the individuals.

Information in dementia care: sense making and a public health direction for the UK?

Providing information is a core focus of policy and practice in dementia care. Information is a vehicle through which people can be enabled or disabled, so it is essential that we ensure that information is available in a way that is accessible and relevant for people with dementia and that it enables personal aspiration and collective identity to be advanced in a way that is to the benefit of those living with dementia. People with dementia need information to support autonomy in making decisions and in acting on those decisions. Information must be provided in a way that is appropriate to the individual and to achieve that requires knowledge of the needs of that individual. However, maintaining autonomy includes, but involves much more than, the provision of information - others need to listen and hear their views and be prepared to act on them. As professionals, we must be aware that the (dementia) information we provide may disrupt the biographical narrative that people with dementia value. Thus, a person-centred approach encourages the sharing of knowledge and information. The (mis)use of information also impacts on the way that society disables, discriminates and applies barriers against people with disability.

Reframing risk management in dementia care through collaborative learning.

Risk management is a complex aspect of practice which can lead to an emphasis on maintaining physical safety, which impacts on the well-being of people with dementia. Education for practitioners in risk management is particularly challenging because of its conceptual nature and diverse perceptions of risk between and within professional groups. The practice development research reported here formed one part of a multisite study and contributed to developing a risk assessment and management framework for use by practitioners in partnership with people with dementia and their families. Practice development research uses learning theories in the process of the research, and in so doing its intent is to not only create new knowledge but to view the research process as also a process of learning for those involved. Twenty practitioners from varying professions participated in five Collaborative Learning Groups, each of at least 2 hours duration, which were held over a 7-month period. Data analysis highlighted contradictions in the care system and in the professional's intention to practice in a person-centred way. These were expressed through the themes of: Seeking Certainty; Making Judgements; Team Working; Managing Complexity; Gathering and Using Information.
