From the 3rd decade in life, almost all parts of our body have an ongoing declining capacity. This includes our: immune system, brain, muscles, aerobic capacity and bones. The consequences are inevitable: - dependence on help from others and vulnerability/ fragility. The age where we reach this state in life depends on the speed of the aging process. In some people, this process is accelerated; that is, they age prematurely turning “old” at an early age. The speed of the ageing process is related to several causes such as life style, genetics, illness etc. which may interact synergistically.
Our main focus is to identify and understand low functional level and accelerated functional decline in the older person by measures of cognitive function, muscle strength, basic mobility, functional independency and immunological biomarkers.
We believe that acutely admitted older medical patient is essential to this research.
Definition of chronic inflammation and development of chronic inflammation risk score. Register-based study using biomarker data from the Danish population-based studies Inter99 (n=5,538) and Monica10 (n=2,602) to develop models for chronic inflammation as a pre-pathological process, predictive of chronic diseases and premature mortality. Project leader: Line Jee Hartmann Rasmussen.
(part of the FAM-CPH study). Cross-sectional and longitudinal investigation of differences in chronic inflammation and biological age between acutely admitted and healthy persons above 65 years, and between younger and older persons. Immune cells will be investigated with flow cytometry (NF-κB and NLRP3 inflammasome activity) and ELISA and Luminex (cytokines) methods. Patients have been included and inclusion of controls is on-going. Project leaders: Juliette Tavenier, Line Jee Hartmann Rasmussen.
MicroRNAs as biomarkers of biological aging in acutely admitted elderly patients. Screening of microRNAs in patients from the DISABLMENT study (acutely admitted patients above 65 years, n=369) to identify a profile of microRNAs associated with biological aging (assessed using physical, physiological, cognitive, and immunological markers, and mortality). The microRNA-profile will be validated in the FAM-CPH study. Project leader: Juliette Tavenier.
Epidemiological strategies aiming to adapt trajectories for older people with multimorbidity: a national register-based study and a prospective clinical cohort study to investigate the hypothesis that older persons can be grouped into homogeneous patterns of multimorbidity, and that these patterns are related to the ageing process, with the use of latent class models. Study 1: Prevalence and overlap of Disease Management Program diseases in older hospitalized patients. Study 2: Ageing process among acutely admitted older medical patients (≥ 65 years) – an explorative latent variable model of multimorbidity: a prospective cohort study. 369 patients will be enrolled. Study 3: Development of patterns of multimorbidity in Denmark among older people (≤ 65 years) – a nationwide registry study. Project leader: Helle Gybel Juul-Larsen.
