Delirium episode as a sign of undetected dementia among community dwelling elderly subjects: a 2 year follow up study

ABSTRACT Objective: to investigate the association between frailty with hospitalization and institutionalization in a follow-up study of elderly residents. Method: the follow-up study was performed in 2008 and 2013 with elderly of both genders, aged 65 years and older who were living in the community-dwelling. The sampling procedure performed was probabilistic, with dual-stage clustering. In 2008, 515 elderly people were interviewed and, in 2013, 262. We used the socioeconomic and demographic data, self-reported morbidity, specific data of hospitalization and institutionalization. Frailty was measured by the Edmonton Frail Scale (EFS), and functional capacity through the Functional Independence Measure. Results: we found the mean gross EFS score was higher among resident elderly who were hospitalized and institutionalized and was statistically significant in both investigated years. Conclusion: the confirmation of association between frailty and hospitalization and institutionalization reinforces the importance of the subject, and highlights frailty as an important tool for risk estimates for these adverse events.

The Difference

We investigated the possible influence of TERC and TERT genetic variation and leukocyte telomere length (LTL) on human lifespan. Four polymorphisms of TERT and three polymorphisms of TERC were examined in a sample of elderly subjects (70–100 years). After nine years of follow-up, mortality data were collected, and sub-samples of long-lived/not long-lived were defined. TERT VNTR MNS16A L/L genotype and TERT rs2853691 A/G or G/G genotypes were found to be associated with a significantly higher risk to die before the age of 90 years, and with a significantly lower age at death. The association between lifespan and LTL at baseline was analyzed in a subsample of 163 subjects. Age at baseline was inversely associated with LTL (p < 0.0001). Mean LTL was greater in the subjects still living than in those no longer living at follow-up (0.79 T/S ± 0.09 vs 0.63 T/S ± 0.08, p < 0.0001). Comparison of age classes showed that, among the 70–79-year-olds, the difference in mean LTL between those still living and those no longer living at follow-up was greater than among the 80–90-year-olds. Our data provide evidence that shorter LTL at baseline may predict a shorter lifespan, but the reliability of LTL as a lifespan biomarker seems to be limited to a specific age (70–79 years).
