Dementia is recognised as the biggest health crisis of our time in terms of high personal and social costs and wider impact on health and social care systems. Increases in people living with dementia and multi-morbidities presents critical challenges for home care worldwide. Health-care systems struggle to provide adequate home-care services, delivering limited care restricted to a single-condition focus. This study explored the experiences and expectations of home care from the multiple perspectives of people living with dementia and multi-morbidities and home-care workers providing support. Findings draw from qualititative semi-structured interviews with people with dementia (N = 2), their partners (N = 2), other partners or family carers (N = 6) and home-care workers (N = 26). Three themes are identified: (a) the preference for and value of home; (b) inadequate home-care provision and enhanced care burden; and (c) limited training and education. Despite continued calls for home-care investment, the focus on reduction in costs hides key questions and further dialogue is required exploring how people with dementia can be supported to live independently and flourish at home. This study considers these complex experiences and care requirements through the prism of disability and human rights frameworks. This paper concludes with consideration of more recent human social rights debate. We discuss critically what this may mean for people living with dementia and consider the implications for co-requisite policy development to optimise available home-care support.

Little is known about the extent to which aging trajectories of different body systems share common sources of variance. We here present a large twin study investigating the trajectories of change in five systems: cardiovascular, respiratory, skeletal, morphometric, and metabolic. Longitudinal clinical data were collected on 3,508 female twins in the TwinsUK registry (complete pairs:740 monozygotic (MZ), 986 dizygotic (DZ), mean age at entry 48.9 ± 10.4, range 18–75 years; mean follow-up 10.2 ± 2.8 years, range 4–17.8 years). Panel data on multiple age-related variables were used to estimate biological ages for each individual at each time point, in linear mixed effects models. A weighted average approach was used to combine variables within predefined body system groups. Aging trajectories for each system in each individual were then constructed using linear modeling. Multivariate structural equation modeling of these aging trajectories showed low genetic effects (heritability), ranging from 2% in metabolic aging to 22% in cardiovascular aging. However, we found a significant effect of shared environmental factors on the variations in aging trajectories in cardiovascular (54%), skeletal (34%), morphometric (53%), and metabolic systems (53%). The remainder was due to environmental factors unique to each individual plus error. Multivariate Cholesky decomposition showed that among aging trajectories for various body systems there were significant and substantial correlations between the unique environmental latent factors as well as shared environmental factors. However, there was no evidence for a single common factor for aging. This study, the first of its kind in aging, suggests that diverse organ systems share non-genetic sources of variance for aging trajectories. Confirmatory studies are needed using population-based twin cohorts and alternative methods of handling missing data.
