During the COVID-19 pandemic, frail older individuals have been identified as a particularly vulnerable group for poor health outcomes, including cognitive decline and dementia. We aimed to reflect on the interaction between frailty and COVID-19 with regards to health consequences.Using a rapid literature review approach, we aimed to identify what it means to be a frail older individual in the COVID-19 pandemic from the perspective of three different settings: community, hospitals, and nursing homes. Four researchers from 4 countries (Ireland, France, Germany, and Brazil) reviewed articles from the MEDLINE database and grey literature including public policy briefs from their countries.In the community, some governments advised to practice "cocooning", i.e. stay-at-home-orders for older individuals. This brought unprecedented restrictions to lifestyles, leading to a potential frailty cascade among older adults. Social frailty likely caused mental ill-health, cognitive and functional decline, increasing the risk for dementia. In hospitals, frailty affected from disease onset to survivorship. The clinical presentation was rather atypical, and the biological findings were more heterogenous. Some resource allocation strategies based on the Clinical Frailty Scale remained questionable and should take into account patients' and carers' needs. A quarter of patients had increased care needs at discharge. However, availability of rehabilitation and support services in the community has been reduced. Frail older adults living in nursing homes were the most vulnerable group. Isolating residents and limiting the spread of COVID-19 was a key difficulty. Reduced visits from relatives, cancelled physical activities, and lack of social engagement worsened cognitive, behavioral, and physical conditions of the residents. There were also positive aspects such as the boom of digital literacy and telemedicine and a renewed debate on age and ageing.The COVID-19 pandemic spotlights the ageing population that is rapidly growing worldwide. Prolonged lifestyle restrictions during the pandemic led to poor health outcomes in frail older individuals, including cognitive decline and dementia. Lessons learned from how frail older individuals are getting through the pandemic provide a unique chance to improve health outcomes, community and health services and how we want to live as ageing societies.

Knowledge of environmental and genetic factors for healthy aging in elderly people is controversial. In addition to this evidence, few studies have been designed for this population.To investigate the relationship between the most frequent apolipoprotein E (APOE) genotypes and mortality in very elderly individuals living in a community and to evaluate survival according to cardiovascular risk factors.A sample of 74 elderly individuals aged ≥ 80 years, from the Veranópolis Project cohort, was selected for APOE genotyping. At baseline, anthropometric variables, glucose and lipid levels, blood pressure, and lifestyle variables (smoking, alcohol consumption, and physical activity) were collected. The Bayer Activities of Daily Living Scale was applied to their caregivers. Total study follow-up was 21 years. Two-sided p0.05 was considered statistically significant.There was no association between APOE genotypes and mortality. However, the risk of death in elderly smokers was 2.30 times higher (hazard ratio [HR], 95% CI 1.01 to 5.24); in individuals with diabetes, it was 3.95 times higher (HR, 95% CI 1.27 to 12.30) than in individuals without diabetes. Subjects who practiced vigorous physical activity had a 51% reduction in risk of death (HR = 0.49, 95% CI 0.27 to 0.88). For an increase of 1 mmHg in systolic blood pressure, there was a 2% reduction (HR = 0.98, 95% CI 0.97 to 0.99) in risk of death.In this sample population, APOE genotypes were not associated with mortality. However, classic cardiovascular risk factors may be important for overall mortality in the very elderly.O conhecimento dos fatores ambientais e genéticos para um envelhecimento bem-sucedido em idosos longevos é controverso. Acrescenta-se a esta evidência, o fato de serem poucos os estudos delineados com essa população.Investigar a relação entre os genótipos mais frequentes da apolipoproteína E (APOE) e a mortalidade em idosos longevos que vivem em comunidade e sua sobrevida de acordo com os fatores de risco cardiovascular.Uma amostra de 74 idosos com 80 anos ou mais da coorte do Projeto Veranópolis foi selecionada para genotipagem da APOE. Na linha de base, foram coletadas variáveis antropométricas, dosagens sanguíneas de glicose e lipídeos, pressão arterial e variáveis de estilo de vida (tabagismo, consumo de álcool e atividade física). A escala Bayer de Atividades da Vida Diária foi aplicada aos cuidadores dos idosos. O tempo de seguimento total do estudo foi 21 anos. Um p0,05 bicaudal foi considerado estatisticamente significativo.Não encontramos associação entre os genótipos da APOE e mortalidade. Entretanto, o risco de morte em idosos fumantes foi 2,30 vezes (hazard ratio [HR]; intervalo de confiança de 95% [IC 95%] 1,01 a 5,24); em diabéticos, 3,95 vezes (HR; IC 95% 1,27 a 12,30) do risco dos não diabéticos. Indivíduos que praticavam atividade física vigorosa tiveram uma redução no risco de óbito em 51% (HR = 0,49; IC 95% 0,27 a 0,88). Para o aumento de 1 mmHg na pressão arterial sistólica houve uma redução de 2% (HR = 0,98; IC 95% 0,97 a 0,99) no risco de morte.Nesta amostra de longevos, não houve associação entre os genótipos da APOE e mortalidade. Entretanto, os fatores de risco cardiovasculares clássicos podem ser importantes para a mortalidade geral em pessoas muito idosas.
