To investigate agreement and reliability among clinicians when diagnosing low back-related leg pain (LBLP) in primary care consulters. ⋯ Reliability was fair among clinicians from different backgrounds when diagnosing LBLP but improved substantially with high confidence in clinical diagnosis.

Several types of stem cells have been successfully demonstrated to exist in the human degenerated intervertebral disc (IVD), which is composed of annulus fibrosus (AF), nucleus pulposus (NP) and cartilage endplate (CEP). However, the differences in the biological characteristics among these and bone marrow derived mesenchymal stem cells (BM-MSCs) remain unclear. ⋯ Our data indicated that all the four types of stem cells shared some similar biological properties (regarding shape, proliferation ability and immunophenotypic expression). CESCs, which had the strongest osteogenic and chondrogenic potentials, may serve as excellent seed cells for NP/cartilage or bone tissue engineering.

To investigate whether axial loading of the spine during MRI (alMRI) instantaneously induces changes in biochemical disc features as reflected by altered quantitative T2 values in patients with chronic low back pain (LBP). ⋯ alMRI instantaneously induces T2-value changes in lumbar discs and is, thus, a feasible method to reveal dynamic, biochemical disc features in patients with chronic LBP.

Observational Study
Emotional distress drives health services overuse in patients with acute low back pain: a longitudinal observational study.
To determine whether emotional distress reported at the initial consultation affects subsequent healthcare use either directly or indirectly via moderating the influence of symptoms. ⋯ Emotional distress in the acute stage of low back pain increased subsequent consultation rates. Interventions that target emotional distress during the initial consultation are likely to reduce costly and potentially inappropriate future healthcare use for patients with non-specific low back pain.

Investigation of self-reported of low back pain (LBP) over the last month and associated health-related quality of life (HRQoL) in a sample of a community-dwelling population aged ≥65. ⋯ LBP appears to be a more permanent condition in the older groups. LBP may be a part of the definition of a subgroup of elderly at risk of becoming frail in relation with higher levels of functional limitations, psychological difficulties and social restrictions, hence globally impaired HRQoL.
