Aging Clinical Trial
Official title:
Biological Aging, Medication, Malnutrition and Inflammation Among Acutely Ill and Healthy Elderly.
In this study, the investigators will investigate and characterize acute medical patients in order to optimize patient courses in the acute care departments, especially with regard to polypharmacy and undernourishment. In addition, the investigators will investigate underlying immunological mechanisms of chronic inflammation and biological aging in this population to improve the current knowledge and possibilities for preventing chronic diseases and acute hospitalization.
Malnutrition:
Malnutrition among elderly is associated with frailty, including loss of weight, muscle mass,
function and quality of life and also with an increased number of hospital admissions. In
this study, the investigators aim to describe the development of and the risk factors for
malnutrition from admission to 4 weeks after discharge, in addition the investigators wish to
characterize the inflammatory state of the malnourished patients.
Inappropriate polypharmacy:
The broad variation among elderly in health, number of chronic diseases, organ function,
biological age and function makes the prescription of drugs to this population a very complex
task with a high risk of inappropriate medication. 5-30% of all non-elective admissions are
caused by inappropriate medications, and many of these are preventable. Therefore, the
investigators aim to investigate the feasibility of a pharmacist-geriatrician medication
review in the acute care department and the effect on the Medication Appropriateness Index
score (MAI-score) .
Chronic inflammation and biological aging:
Chronic inflammation and biological aging promote the development of age-related chronic
diseases. There is a large variation in the rate of aging between individuals, in particular
among the elderly. This means that the chronological age of a person often does not reflect
its true state of aging, the biological age. This challenges the ability to provide
appropriate care and to predict responses to treatment and interventions in elderly patients.
The underlying causes and mechanisms of biological aging and chronic inflammation are not
well understood. There are currently no validated methods for measuring biological age and no
measures of chronic inflammation which can be used in an acute setting. Here, the
investigators aim to test a novel model for chronic inflammation and investigate the role of
the NLRP3 inflammasome, NFkB (nuclear factor kappa light chain enhancer of activated B cells)
and miRNAs in biological aging and chronic inflammation.
The study is prospective with 3 groups of study participants: one group is included in the
Acute Medical Department and two healthy control groups (one young and one older). The
follow-up comprises two predefined examinations and any readmissions at our hospital.
Furthermore, participants are followed in the national registries.
