The place for dementia-friendly communities in England and its relationship with epidemiological need.

OBJECTIVES: The dementia-friendly community (DFC) initiative was set up to enable people living with dementia to remain active, engaged, and valued members of society. Dementia prevalence varies nationally and is strongly associated with the age and sex distribution of the population and level of social deprivation. As part of a wider project to evaluate DFCs, we examined whether there is a relationship between provision of DFCs and epidemiological need. METHODS: Dementia-friendly communities were identified through the formal recognition process of DFC status by the Alzheimer's Society and mapped against areas defined by English Clinical Commissioning Groups. We tested whether provision of a DFC was associated with: (1) dementia prevalence, (2) number of known cases, and (3) known plus estimated number of unknown cases. RESULTS: Of the 209 English Clinical Commissioning Group areas, 115 had at least one DFC. The presence of a DFC was significantly associated with number of known dementia cases (mean difference = 577; 95% CI, 249 to 905; P = 0.001) and unknown dementia cases (mean difference = 881; 95% CI, 349 to 1413; P = 0.001) but not prevalence (mean difference = 0.03; 95% CI, -0.09 to 0.16; P = 0.61). This remains true when controlling for potential confounding variables. CONCLUSIONS: Our findings suggest that DFC provision is consistent with epidemiological-based need. Dementia-friendly communities are located in areas where they can have the greatest impact. A retrospective understanding of how DFCs have developed in England can inform how equivalent international initiatives might be designed and implemented.NIHR Policy Research Programme, PR-R15-0116-2100

National Institute for Health Research Policy Research Programme Project Dementia Friendly Communities: The DEMCOM evaluation (PR-R15-0116- 21003)

Final Report: National Institute for Health Research Policy Research Programme Project Dementia Friendly Communities: The DEMCOM evaluation (PR-R15-0116- 21003) As the number of people living with dementia is increasing globally, Dementia Friendly Communities (DFCs) offer one way of providing the infrastructure and support that can enable people affected by dementia to live well. There is no universally agreed definition of a DFC, and DFCs need not be geographical entities. This study adopted a broad definition, recognising that becoming a DFC is an ongoing process only fully achieved when living with dementia is normalised into a community’s culture, language, infrastructure and activities. A DFC can involve a wide range of people, organisations and geographical areas. A DFC recognises that a person with dementia is more than their diagnosis and that everyone has a role in supporting their independence and inclusion. DFCs in England can apply for official recognition by Alzheimer’s Society as working towards dementia friendly status. A growing number of national and international frameworks and guidance is available to communities seeking to become dementia friendly. Evaluations of DFCs are largely descriptive. While work exists on identifying core outcomes of DFC initiatives, there are very few studies that have tested DFC effectiveness or compared current practice with known need. Evidence on cost effectiveness, cost benefit, social value and social return on investment (SRoI) of DFCs is also missing. This study addresses key gaps in the evidence

Comparing airborne algorithms for greenhouse gas flux measurements over the Alberta oil sands

To combat global warming, Canada has committed to reducing greenhouse gases to be (GHGs) 40 %–45 % below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. Airborne methods can provide regional and area source measurements with small error if ideal conditions for sampling are met. In this study, two airborne mass-balance box-flight algorithms were compared to assess the extent of their agreement and their performance under various conditions. The Scientific Aviation’s (SciAv) Gaussian algorithm and the Environment and Climate Change Canada’s top-down emission rate retrieval algorithm (TERRA) were applied to data from five samples. Estimates were compared using standard procedures, by systematically testing other method fits, and by investigating the effects on the estimates when method assumptions were not met. Results indicate that in standard scenarios the SciAv and TERRA mass-balance box-flight methods produce similar estimates that agree (3%–25%) within algorithm uncertainties (4%– 34%). Implementing a sample-specific surface extrapolation procedure for the SciAv algorithm may improve emission estimation. Algorithms disagreed when non-ideal conditions occurred (i.e., under non-stationary atmospheric conditions). Overall, the results provide confidence in the box-flight methods and indicate that emissions estimates are not overly sensitive to the choice of algorithm but demonstrate that fundamental algorithm assumptions should be assessed for each flight. Using a different method, the Airborne Visible InfraRed Imaging Spectrometer – Next Generation (AVIRIS-NG) independently mapped individual plumes with emissions 5 times larger than the source SciAv sampled three days later. The range in estimates highlights the utility of increased sampling to get a more complete understanding of the temporal variability of emissions and to identify emission sources within facilities. In addition, hourly on-site activity data would provide insight to the observed temporal variability in emissions and make a comparison to reported emissions more straightforward

Genetic mechanisms of critical illness in COVID-19.

Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 ×  10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice

The influence of maternal vulnerability and parenting stress on chronic pain in adolescents in a general population sample: The TRAILS study

Investigating possible psychosocial predictors of unexplained chronic pain in adolescents is crucial in understanding its development and prevention. A general population sample of adolescents (n=2230) from the TRAILS cohort study was investigated longitudinally to assess the influence of maternal vulnerability, in terms of anxiety, depression and stress, and parenting stress at age 10-12years, on the presence of chronic pain at age 12-15years. Of these adolescents, 269 (12.9%) reported experiencing chronic pain, of which 77% reported severe chronic pain and 22% reported multiple chronic pain. Maternal anxiety, maternal stress and higher levels of parenting stress were related to chronic pain at a later age. Subgroup analyses showed similar results for adolescents with severe chronic pain. Mediation analyses indicated that parenting stress mediates the effect between maternal anxiety, or stress, and chronic pain. The findings suggest that interventions to diminish maternal feelings of anxiety and stress, while in turn adjusting maternal behaviour, may prevent the development of chronic pain in adolescenc

A suite of evaluation resources for Dementia Friendly Communities: Development and guidance for use.

Peer reviewed: TrueFunder: National Institute for Health Research (NIHR) Applied Research Collaboration East of England (ARC EoE)OBJECTIVES: In the context of a growing number of dementia friendly communities (DFCs) globally, a need remains for robust evaluation, and for tools to capture relevant evidence. This paper reports the development of a suite of evaluation resources for DFCs through a national study in England. METHODS: Fieldwork took place in six diverse case study sites across England. A mixed methods design was adopted that entailed documentary analysis, focus groups, interviews, observations, and a survey. Participants were people affected by dementia and practice-based stakeholders. A national stakeholder workshop was held to obtain input beyond the research sites. A workshop at the end of the study served to check the resonance of the findings and emerging outputs with stakeholders from the case study DFCs. RESULTS: The study had three key outputs for the evaluation of DFCs: First, an evaluation framework that highlights thematic areas to be considered in evaluating DFCs. Second, a Theory of Change that presents inputs into a DFC and short, medium and longer term outcomes. Third, a matrix for assessing a DFC's degree of maturity, which enables a sense of the kinds of outcomes a DFC might realistically aspire to. These three outputs form a suite of interlinking and complementary evaluation resources for DFCs. CONCLUSIONS: The study has contributed evidence-based resources for monitoring and evaluation that complement existing frameworks. They can be applied to arrive at a detailed assessment of how well a DFC works for people affected by dementia, and at insights into the underlying factors that can guide future policy and practice

A survey of the experience of living with dementia in a dementia-friendly community

Dementia-friendly communities (DFCs) are one way in which people living with dementia can be supported to be active, engaged and valued citizens. Quantitative evaluations of the experiences of those with dementia living within these communities are scarce. This article reports findings from a survey of people living with dementia on their experience of living in a DFC. Two-hundred and forty people living with dementia completed a cross-sectional survey in six DFCs across England. Around half of respondents reported they were aware they were living in a DFC. Being aware of living in a DFC was associated with taking part in leisure activities (p = 0.042), community centre attendance (p = 0.009), being involved in organised activities or groups (p < 0.001), feeling understood (p = 0.008), and feeling valued for their own contributions to the community (p = 0.002). This study illustrates the contribution that surveys can make in facilitating the expression of views and experiences of people living with dementia. Awareness of living within a DFC is associated with greater involvement in, and belonging to, the wider community

Food parenting practices and their association with child nutrition risk status: comparing mothers and fathers

In Canada, little is known about how food parenting practices are associated with young children’s dietary intakes and no studies have examined food parenting practices of Canadian fathers. This study aimed to examine associations between food parenting practices and preschool-age children’s nutrition risk. We conducted a cross-sectional analysis of 31 two-parent families; 31 mothers, 31 fathers and 40 preschool-age children. Parents completed an adapted version of the Comprehensive Feeding Practices Questionnaire. We calculated children’s nutrition risk using their NutriSTEP® score. To account for sibling association, we used generalized estimating equations, adjusting for child age, sex, household income, and parental BMI. Both mothers’ and fathers’ involvement of children in meal preparation were associated with lower child nutrition risk (mother β=-3.45, p=0.02; father β=-1.74, p=0.01), as were their healthy home environment scores (mother β=-8.36, pThe accepted manuscript in pdf format is listed with the files at the bottom of this page.

Dementia-friendly communities: The involvement of people living with dementia.

BACKGROUND: Dementia Friendly Communities (DFCs) offer an approach to community engagement to improve the lives of people living with dementia and their family supporters. The involvement of those living with dementia is key to creating successful DFCs. This paper examines how people affected by dementia were involved in developing and designing DFCs in England, and the impact of their involvement. METHODS: This study used a mixed method case study design in six DFCs in England. Data collection involved documentary analysis, a survey, and interviews and focus groups with service providers and people living with dementia and their supporters. FINDINGS: All six DFCs aspired to involve people living with dementia and their family supporters, but often relied on a small number of people living with dementia. The range of involvement activities in DFCs included Steering Group meetings, wider public consultations, and enabling feedback through data collection methods such as surveys and 'ad hoc' conversations. Organisations within the DFCs with experience of public consultation offered structured opportunities for involvement. There was no evidence of people living with dementia initiating or co-leading the organisation, its direction and/or the activities of the DFCs. CONCLUSION: The involvement of people living with dementia in DFCs went beyond rhetoric, with some evidence of context sensitive and meaningful participation. Approaches towards involvement should focus on involvement in strategic planning, and on harnessing expertise in delivering different involvement activities to optimise participation of a greater breadth of people living with dementia. Engagement with local organisations who work with, and for, people living with dementia, and dedicating the resources needed for involvement work, are crucial for creating DFCs. The success of DFCs are determined by how the needs of people living with dementia are identified, discussed and reviewed by those within the community who are most affected
