Intervertebral disc-related diseases of the cervical and lumbar spine are considered to be occupational diseases, if the occupational and medical prerequisites are fulfilled and the causal connection between the prerequisites is likely. The working conditions include occupational burdens with long-term lifting and carrying of heavy loads or long-term activities in an extremely bent position of the torso, long-term carrying of heavy loads on the shoulders and long-term effects of whole-body vibration in a sitting position. ⋯ Furthermore, the medical expert examines the causal connection between the fulfilled prerequisites, whereby the temporal connection (reaching the minimum load dose before realization of the conform damage pattern) and by exclusion of other competing factors are essential. As of 1 January 2021 the necessity to quit the burdening occupation has been omitted by law.

Meta Analysis
Occupational lifting and adverse pregnancy outcome: a systematic review and meta-analysis.
This systematic review was conducted to help clarify the effect of lifting at work on pregnancy outcome, by focusing on specific exposure categories. A search in Medline and Embase identified 51 articles reporting association of spontaneous abortion (SA), preterm delivery (PTD) or small-for-gestational-age (SGA) infant with exposure to occupational lifting. A global validity score was assigned to each study and six potential sources of bias were considered in sensitivity analyses. ⋯ No association was identified with SGA, nor with lower exposure levels and SA or PTD. These results are reassuring for lower levels of exposure; however, observed associations can guide health professionals' recommendations aimed at the prevention of SA and PTD for pregnant women who frequently lift (or ≥10x/day) heavy (or ≥10 kg) loads at work. Résumé.

Background and aims To systemically review the literature to compare freestyle lifting technique, by muscle activity and kinematics, between people with and without low back pain (LBP). Methods Five databases were searched along with manual searches of retrieved articles by a single reviewer. Studies were included if they compared a freestyle lifting activity between participants with and without LBP. ⋯ The cross-sectional nature of the comparisons does not allow for causation to be determined. Implications The changes described may show embodiment of cautious movement, and the drive to protect the back. There may be value in exploring whether adopting a lifting style closer to that of pain-free people could help reduce LBP.

Meta AnalysisThe impact of occupational activities during pregnancy on pregnancy outcomes: a systematic review and metaanalysis.
Data: An increasing number of studies suggest that exposure to physically demanding work during pregnancy could be associated with increased risks of adverse pregnancy outcomes, but the results remain conflicted and inconclusive. The purpose of this study was to examine the influence of occupational activities during pregnancy on maternal and fetal health outcomes. ⋯ Physically demanding work during pregnancy is associated with an increased risk of adverse pregnancy outcomes.

Meta AnalysisTo Flex or Not to Flex? Is There a Relationship Between Lumbar Spine Flexion During Lifting and Low Back Pain? A Systematic Review With Meta-analysis.
To evaluate whether lumbar spine flexion during lifting is a risk factor for low back pain (LBP) onset/persistence or a differentiator of people with and without LBP. ⋯ There was low-quality evidence that greater lumbar spine flexion during lifting was not a risk factor for LBP onset/persistence or a differentiator of people with and without LBP. J Orthop Sports Phys Ther 2020;50(3):121-130. Epub 28 Nov 2019. doi:10.2519/jospt.2020.9218.
