Published: Guidelines for back-friendly manual patient handling

titel_dollyConcrete recommendations for specific activities in the care sector are given in the fifth publication within the framework of the Dortmund Lumbar Load Study 3 (DOLLY 3).

In DOLLY 3, the third Dortmund Lumbar Load Study, the load on the lumbar spine through manual patient handling was investigated. The current publication (part 5) contains concrete recommendations in the form of task-specific practical action instructions. These are based on pair-wise comparisons of task executions combined with varied spinal loadings, in order to identify the essential differences of posture and force development of the caregiver with respect to a back-friendly handling of patients. In summary, the newly developed scientifically substantiated actions instructions provide an effective basis to limit the biomechanical overload risk for the spine of healthcare workers.

The Dortmund Lumbar Load Studies – DOLLY

The akronym ”DOLLY” originates from the english title ”The Dortmund Lumbar Load Study”. The DOLLYs represent comprehensive investigations regarding the occupationally induced load on the lumbar spine in diverse vocational fields. The initial DOLLY demonstrates a monitoring of lumbar load for complete working shifts, DOLLY 2 provides a lumbar-load register for a variety of typical manual materials handling tasks. DOLLY 3 focuses on care activities. This 5-part study was conducted by the Leibniz Research Centre for Working Environment and Human Factors (IfADo) in intensive cooperation with the German Social Accident Insurance Institution for the Health and Welfare Services (BGW):

  • Part 1: Developing the (laboratory) methodology and exemplary applications
  • Part 2: Deriving relevant criteria for occupational-disease evaluations
  • Part 3: Load reduction via ”small aids” and ”optimized working mode”
  • Part 4: Load modulation while handling obese persons
  • Part 5: Action instructions for back-friendly patient handling

Blueprint for stemm cell differentitaion into liver cells (hepatocytes)

Stem cell research gets more and more important because these cells can be directed to differentiate into practically all mature cell types. This represents a potential solution for therapeutics of severely damaged organs and also an alternative to animal drug and toxicity testing. Nonetheless an essential question still remains: How similar are differentiated stem cells to the desired mature cells, e.g. liver cells? Scientists at IfADo – Leibniz Research Centre for Working Environment and Human Factors in cooperation with partners from EU and UK developed a method for precisely assessing the degree of stem cell-differentiation into mature liver cells (i.e. hepatocytes) based on whole-genome gene expression analysis and statistical models.
