Promotors of Robustness

Aging is a complex multifactorial process. Chronological age is only one of the biopsychosocial factors associated with it. Age-related diseases and functional loss increase with increasing age, but are neither unavoidable nor fully interdependent.

Research Focus

Within the global efforts to shift from lifespan to health span, we focus on specific biomolecular-phenotypical-clinical profiles of frailty and robustness as well as their trajectories overtime. To improve clinical decision-making in advanced age, we dedicate particular attention to multiple organ dysfunction and the weakest links of the organism as a main determinant of frailty and atypical disease presentation; over 80% of the older population suffers from at least one chronic condition in Europe and over half of the German 65+ population suffers from multimorbidity with disastrous consequences for accelerated aging and disability. Therefore, maintenance of overall health, quality of life, wellbeing and biopsychosocial functional integrity as well as disclosing its promoters are an absolute public health priority. Medical actions usually take little or no account of aging physiology, decreased organ reserve, and increased vulnerability. In fact, they display a broad spectrum of iatrogenic implications – with iatrogenic complications being one of the most prominent clinical syndromes with advancing age. Our research focuses on uncovering signatures of the individual, heterogeneous, multifactorial and dynamic oscillatory balance between aging accelerating and decelerating determinants.   

Understanding mechanisms of multidimensional health beyond organ-centered medicine and deficit-oriented coding systems is crucial to manage complexity of aging and maintain biopsychosocial robustness and quality of life.

Our Goals

  • Measuring the above cited individual, heterogeneous, multifactorial and dynamic oscillatory balance between aging accelerating and decelerating determinants is an ambitious goal. To achieve it, disentangling complexity of aging is crucial. We use a highly accurate scaled tool derived from the Comprehensive Geriatric Assessment, the Multidimensional Prognostic Index (MPI).
     
  • Since 2016 we conduct prospective observational studies with the aim of phenotyping older adults admitted to various healthcare settings – general practice, internal medicine and surgical wards, intermediate and intensive care, emergency department, geriatric hospitals, long-term care facilities – by measuring their multiple chronic conditions, medications, nutritional status, mobility, cognition, daily functions and social aspects. By doing so, a continuous number from o to 1 is delivered with 0 meaning no frailty and low risk for poor outcomes and 1 meaning severe frailty and highest mortality risk up to two years after the measurement. This way we could establish the largest multisectoral healthcare cohort and show that the MPI not only assist in clinical routine decision-making, but it can also be considered a proxy of physiological beyond chronological age: it correlates with the well-established MetaboHealth score and lutein plasma levels among several lipophilic micronutrients; it associates with high-variability transcriptome aging clocks, as well as with genetic expression typical of a fasting-like transcriptional program countered in transgenic killifish with more youthful feeding and fasting response, improved metabolic health and longevity.
     
  • In contrast to the sad, unacceptable knowledge that it takes on average 17-20 years for clinical innovations to translate into practice, we have established an agile mechanism to transfer the information derived from the MPI database to the population – awareness and education. Therefore, we provide MD students with gerontologic competencies and skills to expect, recognize, and adequately manage older prefrail and frail adults; we train residents as well as physiotherapists, occupational therapists, neuropsychologists, and nurses on risk for and occurrence of frailty and other age-related syndromes; we empower citizens on best available practices to achieve and maintain health and robustness.
