A Web-Based Self-management App for Living Well With Dementia: User-Centered Development Study

Background: Self-management, autonomy, and quality of life are key constructs in enabling people to live well with dementia. This population often becomes isolated following diagnosis, but it is important for them to feel encouraged to maintain their daily activities and stay socially active. Promoting Independence in Dementia (PRIDE) fosters social inclusion and greater dementia self-management through an interactive handbook. Objective: This study aimed to develop a paper-based PRIDE manual on a web-based platform. Methods: Two overarching stages were used to create the web-based version of PRIDE. The first was Preliminary Development, which encompassed tendering, preliminary development work, consultations, beta version of the website, user testing and consultation on beta version, and production of the final web-based prototype. The second stage was Development of the Final PRIDE App, which included 2 sprints and further user testing. Results: Through a lengthy development process, modifications were made to app areas such as the log-in process, content layout, and aesthetic appearance. Feedback from the target population was incorporated into the process to achieve a dementia-friendly product. The finished PRIDE app has defined areas for reading dementia-related topics, creating activity plans, and logging these completed activities. Conclusions: The PRIDE app has evolved from its initial prototype into a more dementia-friendly and usable program that is suitable for further testing. The finished version will be tested in a reach, effectiveness, adoption, implementation, and maintenance study, with its potential reach, effectiveness, and adoption explored. Feedback gathered during the reach, effectiveness, adoption, implementation, and maintenance study will lead to any further developments in the app to increase its applicability to the target audience and usability

‘Priming’ exercise and O2 uptake kinetics during treadmill running

We tested the hypothesis that priming exercise would speed kinetics during treadmill running. Eight subjects completed a square-wave protocol, involving two bouts of treadmill running at 70% of the difference between the running speeds at lactate threshold (LT) and max, separated by 6-min of walking at 4 km h−1, on two occasions. Oxygen uptake was measured breath-by-breath and subsequently modelled using non-linear regression techniques. Heart rate and blood lactate concentration were significantly elevated prior to the second exercise bout compared to the first. However, kinetics was not significantly different between the first and second exercise bouts (mean ± S.D., phase II time constant, Bout 1: 16 ± 3 s vs. Bout 2: 16 ± 4 s; slow component amplitude, Bout 1: 0.24 ± 0.10 L min−1vs. Bout 2: 0.20 ± 0.12 L min−1; mean response time, Bout 1: 34 ± 4 s vs. Bout 2: 34 ± 6 s; P > 0.05 for all comparisons). These results indicate that, contrary to previous findings with other exercise modalities, priming exercise does not alter kinetics during high-intensity treadmill running, at least in physically active young subjects. We speculate that the relatively fast kinetics and the relatively small slow component in the control (‘un-primed’) condition negated any enhancement of kinetics by priming exercise in this exercise modality

Honey bee foraging distance depends on month and forage type

To investigate the distances at which honey bee foragers collect nectar and pollen, we analysed 5,484 decoded waggle dances made to natural forage sites to determine monthly foraging distance for each forage type. Firstly, we found significantly fewer overall dances made for pollen (16.8 %) than for non-pollen, presumably nectar (83.2 %; P < 2.2 × 10−23). When we analysed distance against month and forage type, there was a significant interaction between the two factors, which demonstrates that in some months, one forage type is collected at farther distances, but this would reverse in other months. Overall, these data suggest that distance, as a proxy for forage availability, is not significantly and consistently driven by need for one type of forage over the other

Outcomes from a collaborative project developing and evaluating a community rehabilitation worker program for Northwestern Ontario First Nations

Introduction: Major inequities exist in levels of health and wellbeing, availability, and access to healthcare services between seniors of Indigenous and non-Indigenous background in Ontario. First Nations elders are 45-55% more frail than the average senior in Ontario. Additionally, needed rehabilitation services are not easily accessible or available in the first language of most First Nations elders within their home communities. A literature review demonstrated community-based rehabilitation assistant models had been successfully developed and implemented in regions facing similar equity and access challenges. Building on these findings, a needs assessment was conducted to capture unique needs and requirements in Northwestern Ontario relating to rehabilitation among First Nations elders. Methods: The needs assessment resulted in four First Nations, three Indigenous health organizations, three rehabilitation health organizations, and two academic institutions iteratively developing and evaluating curriculum for a Community Rehabilitation Worker (CRW) program in treaty territories 5, 9, and Robinson-Superior. The goal of the program is to train local CRWs, familiar with local languages and cultures, to provide rehabilitative services that support ageing in place, health, wellbeing, and quality of life for First Nations elders. The study employed a community participatory action research approach aligning with the OCAP&amp;reg; (Ownership, Control, Access, and Possession) framework for working with Indigenous populations. Seventeen community partners were active participants in the program development, evaluation, and adaptation of the CRW curriculum. Feedback was received through advisory committee meetings, surveys, and individual and group interviews. Results: All 101 participants agreed, across all curriculum modules, that (1) the time allotment was realistic; (2) instructional materials, activities, and resources were appropriate and easy to understand; (3) evaluation activities accurately measured learning; and (4) participants identifying as Indigenous felt that Indigenous culture was adequately reflected. The qualitative findings highlighted the importance of incorporating culture, spirituality, traditions, local language use, and reintegration of First Nations elders into traditional activities and community activities for both the CRW curriculum and rehabilitation efforts. The need for locally available First Nations, elder-focused mental health support, transportation options, and gathering spaces such as those commonly seen in urban areas was also highlighted. Conclusion: The process of iteratively developing and evaluating a CRW program resulted in a Northwestern Ontario college welcoming the first cohort of students to the CRW program in March 2022. The program is co-facilitated with a First Nations Elder and includes components of local culture, language, and the reintegration of First Nations elders into community as part of the rehabilitation efforts. In addition, to appropriately support the quality of life, health, and wellbeing of First Nations elders, the project team called upon provincial and federal governments to work with First Nations to make available dedicated funding to address inequities in resources available to First Nations elders in Northwestern Ontario urban and First Nations remote communities. This included elder-focused transportation options, mental health services, and gathering places. The program implementation will be evaluated with the first cohort of CRWs for further adaptations considering potential scale and spread. As such, the project and findings may also represent a resource for others wishing to pursue similar development using participatory approaches in rural and remote communities both nationally and internationally.

A genome-wide association study identifies risk alleles in plasminogen and P4HA2 associated with giant cell arteritis

Giant cell arteritis (GCA) is the most common form of vasculitis in individuals older than 50 years in Western countries. To shed light onto the genetic background influencing susceptibility for GCA, we performed a genome-wide association screening in a well-powered study cohort. After imputation, 1,844,133 genetic variants were analysed in 2,134 cases and 9,125 unaffected controls from ten independent populations of European ancestry. Our data confirmed HLA class II as the strongest associated region (independent signals: rs9268905, P = 1.94E-54, per-allele OR = 1.79; and rs9275592, P = 1.14E-40, OR = 2.08). Additionally, PLG and P4HA2 were identified as GCA risk genes at the genome-wide level of significance (rs4252134, P = 1.23E-10, OR = 1.28; and rs128738, P = 4.60E-09, OR = 1.32, respectively). Interestingly, we observed that the association peaks overlapped with different regulatory elements related to cell types and tissues involved in the pathophysiology of GCA. PLG and P4HA2 are involved in vascular remodelling and angiogenesis, suggesting a high relevance of these processes for the pathogenic mechanisms underlying this type of vasculitis

Exploring women’s decisions of where to give birth in the Peruvian Amazon; why do women continue to give birth at home? A qualitative study

Background Despite improvements in maternal mortality globally, hundreds of women continue to die daily. The World Health Organisation therefore advises all women in low-and-middle income countries to give birth in healthcare facilities. Barriers to seeking intrapartum care have been described in Thaddeus and Maine’s Three Delays Model, however these decisions are complex and often unique to different settings. Loreto, a rural province in Peru has one of the highest homebirth rates in the country at 31.8%. The aim of this study was to explore facilitators and barriers to facility births and explore women’s experiences of intrapartum care in Amazonian Peru. Methods Through purposive sampling, postnatal women were recruited for semi-structured interviews (n = 25). Interviews were transcribed verbatim and thematically analysed. A combination of deductive and inductive coding was used. Analytical triangulation was undertaken, and data saturation was used to determine when no further interviews were necessary. Results Five themes were generated from the data: 1) Financial barriers; 2) Accessing care; 3) Fear of healthcare facilities; 4) Importance of seeking care and 5) Comfort and traditions of home. Generally, participants realised the importance of seeking skilled care however barriers persisted, across all areas of the Three Delays Model. Barriers identified included fear of healthcare facilities and interventions, direct and indirect costs, continuation of daily activities, distance and availability of transport. Women who delivered in healthcare facilities had mixed experiences, many reporting good attention, however a selection experienced poor treatment including abusive behaviour. Conclusion Despite free care, women continue to face barriers seeking obstetric care in Amazonian Peru, including fear of hospitals, cost and availability of transport. However, women accessing care do not always receive positive care experiences highlighting implications for changes in accessibility and provision of care. Minimising these barriers is critical to improve maternal and neonatal outcomes in rural Peru

Hypothermic preservation of lung allograft inhibits cytokine-induced chemoattractant-1, endothelial leucocyte adhesion molecule, vascular cell adhesion molecule-1 and intracellular adhesion molecule-1 expression

Organ dysfunction is a major clinical problem after lung transplantation. Prolonged cold ischaemia and reperfusion injury are believed to play a central role in this complication. The influence of cold preservation on subsequent warm reperfusion was studied in an isolated, ventilated and perfused rat lung. Rat lungs were flushed with cold Perfadex-solution and stored at 4°C for different time periods. Thereafter lungs were perfused and ventilated for up to 3 h. Physiological parameters, production of inflammatory mediators and leucocyte infiltration were measured before and after perfusion. Lungs subjected to a cold ischaemia time of up to 6 h showed stable physiological conditions when perfused for 3 h. However, cold-ischaemia time beyond 6 h resulted in profound tissue oedema, thereby impairing ventilation and perfusion. Warm reperfusion and ventilation per se induced a strong inflammatory response, as demonstrated by a significant up-regulation of chemokines and adhesion molecules (cytokine-induced chemoattractant-1, intracellular adhesion molecule and endothelial leucocyte adhesion molecule), accompanied by enhanced leucocyte infiltration. Although the up-regulation of inflammatory mediators was blunted in lungs that were subjected to cold ischaemia, this did not influence leucocyte infiltration. In fact, cold ischaemia time correlated with leucocyte sequestration. Although cold preservation inhibits the expression of inflammatory mediators it does not affect leucocyte sequestration during warm reperfusion. Cold preservation might cause impairment of the endothelial barrier function, as evidenced by tissue oedema and profound leucocyte infiltration
