This study explored the concept of ‘giving up’ from the perspective of care staff working in care homes, and their everyday communication and hidden knowledge concerning what they think about this taboo topic and the context it reflects. Moving to a care home is a major transition where cumulative losses can pose risks to mental health in later life. If not recognised, this vulnerability can lead to depression which extends to suicide ideation and behaviours in the form of self-harm and self-neglect. Care homes are a significant place of care until death, yet a discourse of silence means that self-harm and suicide is under-reported or not attended to with specialist expertise. The layperson's concept of an older person ‘giving up’ on life is hardly discussed in the literature. This co-produced qualitative study used an inductive approach to explore this phenomenon through focus groups with 33 care staff across four care homes in South-East England. Findings paint a complex picture, highlighting tensions in providing the right support and creating spaces to respond to such challenging situations. ‘Giving up’ requires skilled detailed assessment to respond to risks alongside improved training and support for paid carers, to achieve a more holistic strategy which capitalises on significant relationships within a wider context.

Despite the fact that urbanisation, population ageing and international migration constitute major societal developments of our time, little attention has been paid to studying them together in a comprehensive manner. In this paper, we argue that, when treating age and ethnicity as practical processes for addressing and identifying with social groups, it is necessary to do so from a ‘doing’ perspective. The question we ask focuses on which social memberships are made relevant or irrelevant in residential environments and how that relevance or irrelevance is established. Drawing upon a quantitative study among individuals of Turkish migrant origin living in Vienna, Austria, we find that it is rather common for the respondents to have been assigned to multiple intersecting social groups and that they were treated unfairly in their own neighbourhoods. However, such ascriptions do not necessarily correspond to objective categorisations of research or subjective identifications. Hence, the discrimination that is present in a neighbourhood does not necessarily lead to decreased place attachment or a diminishing sense of home. In fact, we find that the ‘satisfaction paradox’ is quite common in environmental gerontology and that it may actually intersect with the ‘immigration paradox’. Applying processual intersectionality is not only fruitful for research, it can also improve the conceptualisation of age-friendly cities.

n-3 Fatty acids are associated with better cardiovascular and cognitive health. However, the concentration of EPA, DPA and DHA in different plasma lipid pools differs and factors influencing this heterogeneity are poorly understood. Our aim was to evaluate the association of oily fish intake, sex, age, BMI and APOE genotype with concentrations of EPA, DPA and DHA in plasma phosphatidylcholine (PC), NEFA, cholesteryl esters (CE) and TAG. Healthy adults (148 male, 158 female, age 20–71 years) were recruited according to APOE genotype, sex and age. The fatty acid composition was determined by GC. Oily fish intake was positively associated with EPA in PC, CE and TAG, DPA in TAG, and DHA in all fractions (P≤0·008). There was a positive association between age and EPA in PC, CE and TAG, DPA in NEFA and CE, and DHA in PC and CE (P≤0·034). DPA was higher in TAG in males than females (P<0·001). There was a positive association between BMI and DPA and DHA in TAG (P<0·006 and 0·02, respectively). APOE genotype×sex interactions were observed: the APOE4 allele associated with higher EPA in males (P=0·002), and there was also evidence for higher DPA and DHA (P≤0·032). In conclusion, EPA, DPA and DHA in plasma lipids are associated with oily fish intake, sex, age, BMI and APOE genotype. Such insights may be used to better understand the link between plasma fatty acid profiles and dietary exposure and may influence intake recommendations across population subgroups.
