Loneliness describes a complex experience, the subjective incongruence between one’s desired and perceived social connections. The study of loneliness has increased but mostly through quantitative methods, leaving a gap in the personal experience and understanding of what it means to be lonely. The everyday language used to articulate the personal experience of loneliness remains underexamined. To address this gap, we conducted 18 semi-structured life story interviews with older adult mental health service users. Interviews were conducted via telephone and lasted on average 45 min. Participants were included on the basis of being objectively classified as lonely and ranged in age from 66 to 84. This paper provides a thematic analysis of responses to the question “What does loneliness mean to you?” Responses include subjective and objective aspects, as well as frequency, duration, and intensity, and social, emotional, and existential loneliness. Loneliness is a multidimensional, personal experience, rather than a single construct. Participants discussed loneliness alongside social isolation, depression, grief, feelings of emptiness, purpose, meaning, boredom and hopelessness. These insights are important for informing how we frame loneliness in research, policy, and practice, and for highlighting that our language needs to be sufficiently inclusive to capture the complexity of loneliness, not only for work with mental health service users but in public health.

Carers supporting people with an intellectual disability often rely on others to manage the burden of care. This research aims to compare the differences between carer groups and understand the predictors of loneliness changes and burden for carers of people with an intellectual disability. Data from the international CLIC study were analysed. In total, 3930 carers responded from four groups; people who care for those with mental health difficulties (n = 491), dementia (n = 1888), physical disabilities (n = 1147), and Intellectual disabilities (n = 404). Cross tabulation and the chi-squared test were used to compare group compositions and binary logistic regression to model predictors within the intellectual disability group. A total of 65% of those caring for people with an intellectual disability experienced increased burden, and 35% of carers of people with an intellectual disability and another condition experienced more severe loneliness. Becoming severely lonely was predicted by feeling burdened by caring (AOR, 15.89) and worsening mental health (AOR, 2.13) Feeling burden was predicted by being aged between 35 and 44 (AOR, 4.24), poor mental health (AOR, 3.51), and feelings of severe loneliness prior to the pandemic (AOR, 2.45). These findings demonstrate that those who were already struggling with caring experienced the greatest difficulties during the COVID-19 lockdowns.

Background: In low- and middle-income countries, including sub-Saharan Africa little is known about the experiences with caring for people living with dementia. The purpose of this systematic review and narrative synthesis was to examine the experiences with caring for older people living with dementia at home. Results: In total, 366 abstracts were identified and following screening, 19 studies were included in the synthesis. Six themes were identified: conceptualising dementia, caregiving arrangements, the impact of caregiving, caregiver identity and role, managing caregiving, unmet caregiver needs. Conclusion: There is a dearth of research in relation to caregiving for older people living with dementia in sub-Saharan Africa. There is need for better information campaigns and support programs directed at family and professional caregivers in this context.

The COVID-19 global pandemic and subsequent public health social measures have challenged our social and economic life, with increasing concerns around potentially rising levels of social isolation and loneliness. This paper is based on cross-sectional online survey data (available in 10 languages, from 2 June to 16 November 2020) with 20,398 respondents from 101 different countries. It aims to help increase our understanding of the global risk factors that are associated with social isolation and loneliness, irrespective of culture or country, to support evidence-based policy, services and public health interventions. We found the prevalence of severe loneliness was 21% during COVID-19 with 6% retrospectively reporting severe loneliness prior to the pandemic. A fifth were defined as isolated based on their usual connections, with 13% reporting a substantial increase in isolation during COVID-19. Personal finances and mental health were overarching and consistently cross-cutting predictors of loneliness and social isolation, both before and during the pandemic. With the likelihood of future waves of COVID-19 and related restrictions, it must be a public health priority to address the root causes of loneliness and social isolation and, in particular, address the needs of specific groups such as carers or those living alone.

Vitamin D deficiency is often associated with adverse health outcomes in older adults. The circulating 25-hydroxyvitamin D (25(OH)D) status predominately relies on UV exposure. However, the extent of which northerly latitude exasperates deficiency is less explored in ageing. We aimed to investigate vitamin D deficiency in community-dwelling, older adults, residing at latitudes 50–55° north. This study was comprised of 6004 adults, aged >50 years from wave 6 (2012–2013) of the English Longitudinal Study of Ageing (ELSA). Deficiency was categorised by two criteria: Institute of Medicine (IOM) (<30 nmol/L) and Endocrine Society (ES) (50 years had 25(OH)D concentrations <50 nmol/L. These findings demonstrate that low vitamin D status is highly prevalent in older English adults and the crucial importance of public health strategies throughout midlife and older age to achieve optimal vitamin D status.

Background: BIOMARKAPD seeks to diminish the barriers associated with the clinical use of cerebrospinal fluid (CSF) biomarker analysis by reducing variation in CSF laboratory methodologies and generating consensus recommendations on their clinical in

Aim: Neurofilament light (NfL) chain, a putative cerebrospinal fluid biomarker, can support neurodegenerative disease diagnosis and indicate disease severity and prognosis. Universal validation protocols when used to measure biomarkers can reduce pre and analytical laboratory variation, thus increasing end-user confidence in the consistency of validation data across sites. Methodology: Here, a commercially available NfL ELISA (UmanDiagnostics, Umeå, Sweden) was validated in a multicentered setting using comprehensive newly developed standard operating procedures. Results: The data showed good assay sensitivity and intra and interassay precision. Interlaboratory precision was, however, suboptimal. Conclusion: The UmanDiagnostics assay is suitable for the quantification of NfL in human cerebrospinal fluid. However, sources of interlaboratory variation in the data require further investigation.

A frailty paradigm would be useful in primary care to identify older people at risk, but appropriate metrics at that level are lacking. We created and validated a simple instrument for frailty screening in Europeans aged ≥50. Our study is based on the first wave of the Survey of Health, Ageing and Retirement in Europe (SHARE, http://www.share-project.org), a large population-based survey conducted in 2004-2005 in twelve European countries.
