Background: Patient and public involvement (PPI) is a critical priority in research, policy, academia and advocacy organizations. PPI in dementia research is gaining momentum. However, these efforts are missing in international projects aimed at those living with advanced dementia in long‐term care (LTC) homes. Additional complexities can arise in enacting PPI within the context of integration of a palliative approach to care and experiences around end‐of‐life in (EOL) dementia. The mySupport study involved implementing the Family Carer Decision Support (FCDS) intervention for care partners of those living with advanced dementia in LTC in six countries. Research Design and Objective: An interpretive description study was conducted to explore the perspectives of international researchers from six countries on engaging people with lived experiences of dementia and EOL care in research processes. The findings from this study informed the development of a PPI strategy and a subsequent toolkit for the FCDS intervention. Findings: Thirty‐eight interviews were completed with project researchers: 12 from the United Kingdom, 8 from Canada, 7 from Ireland, 4 each from Italy and The Netherlands and 3 from the Czech Republic. Four broad themes describe international researchers' perspectives on advancing methods of engagement for people with lived experiences of dementia and EOL in international PPI activities: (1) Groundwork to engage in research; (2) planning for research activities is key; (3) focus on meaningful engagement and (4) having foresight for practical issues shaping PPI. Discussion and Implications: International projects that involve PPI can present many sources of challenges. The findings in this study highlight important considerations for foundational work for incorporating PPI in international projects. Learning from world leaders and those with lived experiences in various regions can be insightful and help share tools and resources. Patient or Public Contribution: PPI was envisioned as a critical part of conducting the mySupport study. The findings from this study informed the development of a PPI strategy and an international Strategic Guiding Council that included family carers of those living with advanced dementia in LTC homes in six countries. This manuscript focused on the perspectives of researchers on their engagement with people with lived experiences of dementia and EOL. The perspectives of persons with lived experiences on engaging in the mySupport research study will be reported in a forthcoming manuscript. [ABSTRACT FROM AUTHOR]

We conducted genomic characterization based on SNP and SilicoDArT markers on the invasive Himalayan balsam (Impatiens glandulifera) plants originating from native and non‐native regions of their distribution. When genetic relationships were explored by PCoA using SNP and SilicoDArT marker data, the first, second, and third principal coordinates explained altogether 37.4% and 31.0% of the variability, respectively. Samples from the UK, Canada, and Pakistan were grouped together, while Indian plants were clearly distinct based on SNP markers but relatively close to the UK–Canada–Pakistan group based on SilicoDArT markers. Constructed trees differentiated individuals into clusters resembling the PCoA patterns. The Bayesian BAPS analysis performed for the SNP data revealed that the individuals were distributed in seven clusters, representing samples from each of the four Finnish populations, India, Pakistan, and the combination of the UK and Canada. Similar clustering was visible in the UPGMA tree. The Indian cluster did not display any ancestral gene flow with the others, while the Pakistani cluster showed ancestral gene flow only with the combined UK and Canada cluster. Furthermore, the latter cluster displayed ancestral gene flow with the Finnish populations varying from 0% to 3.1%. The BAPS analyses conducted for the SilicoDArT data differ slightly: The individuals were distributed in nine clusters, and the Indian cluster exhibited ancestral gene flow with the mixed cluster including Canadian, Pakistani, and UK samples, and one Finnish sample. The AMOVA showed that 45% and 26% of variation was present among the I. glandulifera groups/populations and the rest within them based on SNP and SilicoDArT markers, respectively. The Bayesian BAPS analyses and the gene flow networks were the most informative tools for resolving relationships among native and introduced plants. It is notable that the small sample sizes for non‐Finnish plant materials may affect the accuracy of the gene flow and other estimates. [ABSTRACT FROM AUTHOR]
